Building energy simulations can be used to predict a building's interior conditions, along with the energy use associated with keeping these conditions comfortable. These models simulate the loads on the building (e.g., internal gains, envelope heat transfer), determine the operation of the space conditioning equipment, and then calculate the building's temperature and humidity throughout the year. The indoor temperature and humidity are affected not only by the loads and the space conditioning equipment, but also by the capacitance of the building materials, which buffer changes in temperature and humidity. This research developed an empirical method to extract whole-house model inputsmore » for use with a more accurate moisture capacitance model (the effective moisture penetration depth model). The experimental approach was to subject the materials in the house to a square-wave relative humidity profile, measure all of the moisture transfer terms (e.g., infiltration, air conditioner condensate) and calculate the only unmeasured term: the moisture absorption into the materials. After validating the method with laboratory measurements, we performed the tests in a field house. A least-squares fit of an analytical solution to the measured moisture absorption curves was used to determine the three independent model parameters representing the moisture buffering potential of this house and its furnishings. Follow on tests with realistic latent and sensible loads showed good agreement with the derived parameters, especially compared to the commonly-used effective capacitance approach. These results show that the EMPD model, once the inputs are known, is an accurate moisture buffering model.« less

1. The aim of this study was to investigate if male-to-female aggression of common pheasants in the course of the breeding season was related to the concentration of plasma testosterone and/or other biochemical plasma indicators in male pheasants housed in breeding cages. The influence of season on the concentration of testosterone and biochemical indicators was also investigated. 2. Males were divided into non-aggressive and aggressive groups during the breeding season based on ethological evaluation. At the beginning, in the middle and at the end of the breeding season, a blood sample was taken from all males on the same day and the concentration of selected biochemical indicators and the total circulating testosterone in the plasma were determined. 3. Male-to-female aggression during the breeding season of pheasants was not influenced by the total plasma testosterone of males. 4. The concentration of total plasma testosterone in males decreased gradually during the breeding season. 5. Male-to-female aggression of pheasants did not have a significant effect on any of the assessed biochemical indicators. 6. The influence of the breeding season affected the activities of alanine aminotransferase and aspartate aminotransferase as well as the concentrations of glucose, magnesium, potassium and chloride in the blood plasma of cage-housed male pheasants.

Group formation of rhesus monkeys, often leads to victims of repeated attacks by the high ranking animal. We reported a case of an injured middle ranking monkey from repetitive and persistent aggression. 4-male rhesus group was formed by a rapid group formation strategy 2 years ago. One monkey in the group suddenly showed depressive and reluctant movement. Physical examination revealed multiple bite wounds and scars in the dorsal skin. Overall increased opacity of the dorsal soft tissue and some free air was observed on radiographic examination. An unidentified anaerobic gram negative bacillus was isolated from the bacterial culture. Reconstructive surgery was performed and in consequence, the wound was clearly reconstructed one week later. Eventually, the afflicted monkey was separated and housed apart from the hierarchical group. This case report indicate that group formation in rhesus monkeys is essentially required sufficient time and stages, as well as more attention and a progressive contact program to reduce animal stress and fatal accidents.

Background Research shows that children with Attention Deficit/Hyperactivity Disorder are at elevated risk of criminality. However, several issues still need to be addressed in order to verify whether hyperactivity in itself plays a role in the prediction of criminality. In particular, co-occurrence with other behaviors as well as the internal heterogeneity in ADHD symptoms (hyperactivity and inattention) should be taken into account. The aim of this study was to assess the unique and interactive contributions of hyperactivity to the development of criminality, whilst considering inattention, physical aggression and family adversity. Methodology/Principal Findings We monitored the development of a population-based sample of kindergarten children (N = 2,741). Hyperactivity, inattention, and physical aggression were assessed annually between the ages of 6 and 12 years by mothers and teachers. Information on the presence, the age at first charge and the type of criminal charge was obtained from official records when the participants were aged 25 years. We used survival analysis models to predict the development of criminality in adolescence and adulthood: high childhood hyperactivity was highly predictive when bivariate analyses were used; however, with multivariate analyses, high hyperactivity was only marginally significant (Hazard Ratio: 1.38; 95% CI: 0.94–2.02). Sensitivity analyses revealed that hyperactivity was not a consistent predictor. High physical aggression was strongly predictive (Hazard Ratio: 3.44; 95% CI: 2.43–4.87) and its role was consistent in sensitivity analyses and for different types of crime. Inattention was not predictive of later criminality. Conclusions/Significance Although the contribution of childhood hyperactivity to criminality may be detected in large samples using multi-informant longitudinal designs, our results show that it is not a strong predictor of later criminality. Crime prevention should instead target children with

Calcium and dairy product intakes have been positively associated with prostate cancer risk. An imbalance in concentrations of calcium and magnesium has been associated with multiple chronic diseases, although few studies have examined the relation with prostate cancer aggressiveness. The goal of this study was to examine the association between dietary intakes of calcium and magnesium, the calcium-to-magnesium ratio (Ca:Mg), and dairy products and prostate cancer aggressiveness. Dietary intake was assessed with the use of an interviewer-administered modified National Cancer Institute Diet History Questionnaire in 996 African American and 1064 European American men with a recent histologically confirmed diagnosis of prostate cancer from the North Carolina-Louisiana Prostate Cancer Project (PCaP). High-aggressive disease was defined as Gleason sum ≥8, or prostate-specific antigen (PSA) >20 ng/mL, or Gleason score ≥7 and clinical stage T3-T4. The comparison group was all other prostate cancer cases. Logistic regression was used to determine the adjusted ORs and 95% CIs for high-aggressive prostate cancer by tertile of diet and supplement exposures. There was a positive association across tertiles of dietary Ca:Mg intake, with odds of high-aggressive prostate cancer in the upper tertiles as follows-OR for tertile 2 compared with tertile 1: 1.38 (95% CI: 1.01, 1.88); OR for tertile 3 compared with tertile 1: 1.46 (95% CI: 1.06, 2.02). When stratified by race, the positive association was more pronounced in African American men (OR for tertile 3 compared with tertile 2: 1.62; 95% CI: 1.04, 2.53). Men who reported the highest daily consumption of whole-fat milk had a 74% increased odds of high-aggressive prostate cancer compared with non-whole-fat milk drinkers, which was attenuated after adjustment for potential mediating factors, such as saturated fat and Ca:Mg intake. Among both African American and European American men diagnosed with prostate cancer, a higher Ca

Researchers studying the murine response to stress generally use mice housed under standard, nationally mandated conditions as controls. Few investigators are concerned whether basic physical aspects of mouse housing could be an additional source of stress, capable of influencing the subsequent impact of an experimentally applied stressor. We have recently become aware of the potential for housing conditions to impact important physiological and immunological properties in mice. Here we sought to determine whether housing mice at standard temperature (ST; 22 °C) vs. thermoneutral temperature (TT; 30 °C) influences baseline expression of heat shock proteins (HSPs) and their typical induction following a whole body heating. There were no significant differences in baseline expression of HSPs at ST and TT. However, in several cases, the induction of Hsp70, Hsp110 and Hsp90 in tissues of mice maintained at ST was greater than at TT following 6 h of heating (which elevated core body temperature to 39.5 °C). This loss of HSP induction was also seen when mice housed at ST were treated with propranolol, a β-adrenergic receptor antagonist, used clinically to treat hypertension and stress. Taken together, these data show that housing temperature significantly influences the expression of HSPs in mice after whole body heating and thus should be considered when stress responses are studied in mice.

Building America Case Study: Sealed Crawl Spaces with Integrated Whole-House Ventilation in a Cold Climate, Ithaca, New York

DOE Office of Scientific and Technical Information (OSTI.GOV)

"9One method of code-compliance for crawlspaces is to seal and insulate the crawlspace, rather than venting to the outdoors. However, codes require mechanical ventilation; either via conditioned supply air from the HVAC system, or a continuous exhaust ventilation strategy. As the CARB's building partner, Ithaca Neighborhood Housing Services, intended to use the unvented crawlspace in a recent development, CARB was interested in investigating a hybrid ventilation method that includes the exhaust air from the crawlspace as a portion of an ASHRAE 62.2 compliant whole-house ventilation strategy. This hybrid ventilation method was evaluated through a series of long-term monitoring tests thatmore » observed temperature, humidity, and pressure conditions through the home and crawlspace. Additionally, CARB worked with NREL to perform multi-point tracer gas testing on six separate ventilation strategies - varying portions of 62.2 required flow supplied by the crawlspace fan and an upstairs bathroom fan. The intent of the tracer gas testing was to identify effective Reciprocal Age of Air (RAoA), which is equivalent to the air change rate in well-mixed zones, for each strategy while characterizing localized infiltration rates in several areas of the home.« less

Few studies have focused on the neuroanatomy of aggressive behavior in children younger than 10 years. Here, we explored the neuroanatomical correlates of aggression in a population-based sample of 6- to 9-year-old children using a multiple-informant approach. Magnetic resonance (MR) scans were acquired from 566 children from the Generation R study who participated in the Berkeley Puppet Interview and whose parents had completed the Child Behavior Checklist. Linear regression analyses were used to examine associations between aggression and amygdala and hippocampal volume. We performed surface-based analyses to study the association between aggression and cortical thickness, surface area, and gyrification. Aggressive behavior was associated with smaller amygdala (p < .05) but not hippocampal volume. Aggression was associated with a thinner cortex in the left precentral cortex (p < .01) and in a cluster including the right inferior parietal, supramarginal, and postcentral cortex (p < .001). Gender moderated the association between aggression and cortical thickness in the right medial posterior cortex (p = .001) and the right prefrontal cortex (p < .001). Aggression was associated with decreased gyrification in a large cluster including the right precentral, postcentral, frontal, and parietal cortex (p = .01). Moreover, aggression was associated with decreased gyrification in the right occipital and parietal cortex (p = .02). We found novel evidence that childhood aggressive behavior is related to decreased amygdala volume, decreased sensorimotor cortical thickness, and decreased global right hemisphere gyrification. Aggression is related to cortical thickness in regions associated with the default mode network, with negative associations in boys and positive associations in girls.

This cross-sectional, population-based study aimed to evaluate the prevalence of weapons possession and associated factors and involvement in physical aggression among adolescents 15 to 18 years of age (n = 960) in the city of Pelotas, Rio Grande do Sul State, Brazil. Ninety of the city's 448 census tracts were selected, and 86 houses in each tract were visited. The statistical analysis used Poisson regression. Prevalence rates in the sample were 22.8% for involvement in fights with physical aggression and 9.6% for weapons possession in the previous 12 months. The study concluded that young males that use alcohol and/or illegal drugs and present minor psychiatric disorders show a higher probability of weapons possession and involvement in physical fights.

Phthalates are widely used as plasticizers in household products. Several studies have reported an association between phthalate exposure and an increased risk of allergies. The present study estimated phthalate exposure in children aged 6-12years and assessed potential correlations with allergies. House dust samples were collected from floors and multi-surface objects >35cm above the floor. Urine samples were collected from the first morning void of the day. Daily phthalate intake (DI dust and DI) was estimated using both house dust and urinary metabolite concentrations. Exposure to di-2-ethylhexyl phthalate (DEHP) in floor dust was associated with parental-reported rhino-conjunctivitis. After stratification by gender, this trend was found to only occur in boys. Furthermore, urinary mono-isobutyl phthalate was inversely associated with parental-reported wheeze in boys. DI dust of benzyl butyl phthalate (BBzP) and DEHP were significantly correlated with DI_BBzP and DI_DEHP, respectively. These correlations were stronger with floor than with multi-surface dust. Our results suggest that, among Japanese children, house dust from low surfaces, such as living room floors, might play a meaningful role in the indoor environmental exposure pathway for BBzP and DEHP.

2013-05-01

Data were collected from 121 staff members (20 direct support staff teams) on background characteristics of the individual staff members and their teams (gender, age, years of work experience, position and education), the frequency and form of aggression of clients with an intellectual disability (verbal or physical), staff members' attitudes towards aggression, and the types of behavioural interventions they executed (providing personal space and behavioural boundary-setting, restricting freedom and the use of coercive measures). Additionally, client group characteristics (age of clients, type of care and client's level of intellectual disability) were assessed. Multilevel analyses (individual and contextual level) were performed to examine the relations between all studied variables and the behavioural interventions. The results showed that for providing personal space and behavioural boundary-setting as well as for restricting freedom, the proportion of variance explained by the context (staff team and client group characteristics) was three times larger than the proportion of variance explained by individual staff member characteristics. For using coercive measures, the context even accounted for 66% of the variance, whereas only 8% was explained by individual staff member characteristics. A negative attitude towards aggression of the direct support team as a whole proved to be an especially strong predictor of using coercive measures. To diminish the use of coercive measures, interventions should therefore be directed towards influencing the attitude of direct support teams instead of individual staff members.

2018-05-01

Gender differences in play behavior and physical aggression have been consistently reported. Theoretical perspectives concerning evolutionary, social, and social-cognitive mechanisms suggest that male-typical play behavior during childhood increases subsequent physical aggression. The evidence supporting these connections is limited, however. The present study investigated the association between gender-typed play behavior in early childhood and physical aggression in early adolescence using a sample drawn from a longitudinal, population study, the Avon Longitudinal Study of Parents and Children. Based on gender-typed play behavior as measured by the Pre-School Activities Inventory at age 3.5 years, samples of masculine (64 boys, 60 girls), feminine (80 boys, 66 girls), and randomly selected control children (55 boys, 67 girls) were recruited at age 13 years and administered the Reinisch Aggression Inventory. After controlling for a range of sociodemographic variables, maternal characteristics, and behavioral problems, including hyperactivity and conduct problems at age 3.5, significant group differences in physical aggression at age 13 were found among children classified as masculine, control, and feminine at age 3.5. Masculine children exhibited significantly more physical aggression than control children or feminine children, and control children exhibited significantly more physical aggression than feminine children. The association between gender-typed play behavior and physical aggression was not moderated by sex. These results suggest that the degree of childhood gender-typed play behavior independently predicts the degree of physical aggression at adolescence in boys and in girls.

The UK-DALE dataset, domestic appliance-level electricity demand and whole-house demand from five UK homes.

Many countries are rolling out smart electricity meters. These measure a home's total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the 'ground truth' demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

The current study examined multilevel risk factors and developmental assets on longitudinal trajectories of aggressive behavior in a diverse sample of rural adolescents. Using ecological and social capital theories, we explored the impact of positive and negative proximal processes, social capital, and contextual characteristics (i.e., school and neighborhood) on adolescent aggression. Data came from the Rural Adaptation Project, which is a 5-year longitudinal panel study of more than 4,000 middle and high school students from 40 public schools in two rural, low income counties in North Carolina. A three-level HLM model (N = 4,056 at Wave 1, 4,251 at Wave 2, and 4,256 at Wave 3) was estimated to predict factors affecting the change trajectories of aggression. Results indicated that negative proximal processes in the form of parent-adolescent conflict, friend rejection, peer pressure, delinquent friends, and school hassles were significant predictors of aggression. In addition, social capital in the form of ethnic identity, religious orientation, and school satisfaction served as buffers against aggression. Negative proximal processes were more salient predictors than positive proximal processes. School and neighborhood characteristics had a minimal impact on aggression. Overall, rates of aggression did not change significantly over the 3-year study window. Findings highlight the need to intervene in order to decrease negative interactions in the peer and parent domains. © 2015 Wiley Periodicals, Inc.

Introducing a new cat into a household with one or more resident cats can be a significant source of stress for the cats involved. These studies sought to determine if rabbit maternal-neonatal pheromone (2-methyl-2-butenal [2M2B]) in litter impacted cat social behaviors and litter box use. Study 1 determined that cats preferred to eliminate in litter containing 2M2B; other semiochemicals tested did not change litter box use. Cats prone to aggression were identified in an intermediate pilot study, and eight pairs of these cats were selected for Study 2. In Study 2, cat pairs were provided litter containing either vehicle or 2M2B for 24 hours. Cats experiencing control litter displayed more aggression during the first 6 hours (p < .01) and spent more time using the litter box 12 hours and 18 hours after pairing compared with cats experiencing litter with 2M2B (p = .02). These results suggest 2M2B-infused cat litter may act as an interomone in cats housed domestically to prevent initial occurrences of aggression and may improve cat welfare in multicat households.

Seven-year-olds' aggressive choices in a computer game can be predicted in infancy.

2018-05-01

Concerns about the relationship between computer games and children's aggression have been expressed for decades, but it is not yet clear whether the content of such games evokes aggression or a prior history of aggression promotes children's interest in aggressive games. Two hundred and sixty-six 7-year-old children from a nationally representative longitudinal sample in the UK played a novel computer game (CAMGAME) in which the child's avatar encountered a series of social challenges that might evoke aggressive, prosocial or neutral behaviour. Aggressive choices during the game were predicted by well-known risk factors for aggressive conduct problems and the children's own early angry aggressiveness as infants. These findings suggest that children who are predisposed to aggression bring those tendencies to virtual as well as real environments. © 2017 The Authors.

2016-01-01

Background We hypothesized intrauterine growth restricted offspring (IUGR) demonstrate higher rates of aggression and higher dominance ranks than control (CTR) offspring with normal weight at term; if aggressive behavior is advantageous during resource scarcity, developmental programming may lead to an association between aggression and IUGR. Methods We studied 22 group-housed baboons (ages 3-5 years). CTR (male n=8, female n=5) mothers ate ad libitum. IUGR (male n=4, female n=5) mothers were fed 70% feed eaten by CTR mothers during pregnancy and lactation. Results IUGR showed higher rates of aggressive displays (p<0.01) and friendly displays (p<0.02). Dominance ranks and physical aggression rates did not differ between groups. Conclusions High rates of IUGR aggressive display might reflect developmental programming of behavioral phenotypes enhancing fitness. Friendly displays may reflect reconciliation. Potential mechanisms include neurodevelopment and learning. Exploration of IUGR as a risk factor for behavioral patterns is important for developing diagnostic and therapeutic strategies.

In order to quantify the performance of a combined whole-house dehumidifier (WHD) AC system, researchers from the Consortium of Advanced Residential Buildings (CARB) team monitored the operation of two Lennox AC systems coupled with a Honeywell DH150 TrueDRY whole-house dehumidifier for a six-month period. By using a WHD to control moisture levels (latent cooling) and optimizing a central AC to control temperature (sensible cooling), improvements in comfort can be achieved while reducing utility costs. Indoor comfort for this study was defined as maintaining indoor conditions at below 60% RH and a humidity ratio of 0.012 lbm/lbm while at common drymore » bulb set point temperatures of 74°-80°F. In addition to enhanced comfort, controlling moisture to these levels can reduce the risk of other potential issues such as mold growth, pests, and building component degradation. Because a standard AC must also reduce dry bulb air temperature in order to remove moisture, a WHD is typically needed to support these latent loads when sensible heat removal is not desired.« less

Many countries are rolling out smart electricity meters. These measure a home’s total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the ‘ground truth’ demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

The number of deteriorated multi-family housing complexes in South Korea continues to rise, and consequently their electricity consumption is also increasing. This needs to be addressed as part of the nation's efforts to reduce energy consumption. The objective of this research was to develop a decision support model for determining the need to improve multi-family housing complexes. In this research, 1664 cases located in Seoul were selected for model development. The research team collected the characteristics and electricity energy consumption data of these projects in 2009-2010. The following were carried out in this research: (i) using the Decision Tree, multi-family housing complexes were clustered based on their electricity energy consumption; (ii) using Case-Based Reasoning, similar cases were retrieved from the same cluster; and (iii) using a combination of Multiple Regression Analysis, Artificial Neural Network, and Genetic Algorithm, the prediction performance of the developed model was improved. The results of this research can be used as follows: (i) as basic research data for continuously managing several energy consumption data of multi-family housing complexes; (ii) as advanced research data for predicting energy consumption based on the project characteristics; (iii) as practical research data for selecting the most optimal multi-family housing complex with the most potential in terms of energy savings; and (iv) as consistent and objective criteria for incentives and penalties.

Effects of viewing relational aggression on television on aggressive behavior in adolescents: A three-year longitudinal study.

PubMed

Coyne, Sarah M

2016-02-01

Most researchers on media and aggression have examined the behavioral effects of viewing physical aggression in the media. Conversely, in the current study, I examined longitudinal associations between viewing relational aggression on TV and subsequent aggressive behavior. Participants included 467 adolescents who completed a number of different questionnaires involving media and aggression at 3 different time points. Results revealed that viewing relational aggression on TV was longitudinally associated with future relational aggression. However, early levels of relational aggression did not predict future exposure to televised relational aggression. Conversely, there was a bidirectional relationship between TV violence and physical aggression over time. No longitudinal evidence was found for a general effect of viewing TV, as all significant media effects were specific to the type of aggression viewed. These results support the general aggression model and suggest that viewing relational aggression in the media can have a long-term effect on aggressive behavior during adolescence.

The goal was to examine the association between the use of corporal punishment (CP) against 3-year-old children and subsequent aggressive behavior among those children. Respondents (N = 2461) participated in the Fragile Families and Child Well-being Study (1998-2005), a population-based, birth cohort study of children born in 20 large US cities. Maternal reports of CP, children's aggressive behaviors at 3 and 5 years of age, and a host of key demographic features and potential confounding factors, including maternal child physical maltreatment, psychological maltreatment, and neglect, intimate partner aggression victimization, stress, depression, substance use, and consideration of abortion, were assessed. Frequent use of CP (ie, mother's use of spanking more than twice in the previous month) when the child was 3 years of age was associated with increased risk for higher levels of child aggression when the child was 5 years of age (adjusted odds ratio: 1.49 [95% confidence interval: 1.2-1.8]; P < .0001), even with controlling for the child's level of aggression at age 3 and the aforementioned potential confounding factors and key demographic features. Despite American Academy of Pediatrics recommendations to the contrary, most parents in the United States approve of and have used CP as a form of child discipline. The current findings suggest that even minor forms of CP, such as spanking, increase risk for increased child aggressive behavior. Importantly, these findings cannot be attributed to possible confounding effects of a host of other maternal parenting risk factors.

This study investigated the aggressive behaviour of all mentally ill patients within a whole psychiatric hospital with a catchment area of 325 000 inhabitants over a 1-year period (i) to assess the 1-year prevalence and characteristics of aggressive episodes and index inpatients, and (ii) to identify predictors of patients at risk by a multivariate approach. Staff Observation of Aggression Scale was used to assess aggressive behaviour. Characteristics of index inpatients were compared with those of non-index inpatients. Logistic regression analysis was applied to identify risk factors. A total of 171 out of 2210 admitted patients (7.7%) exhibited 441 aggressive incidents (1.7 incidents per bed per year). Logistic regression analyses revealed as major risk factors of aggression: diagnoses (organic brain syndromes OR = 3.6, schizophrenia OR = 2.9), poor psychosocial living conditions (OR = 2.2), and critical behaviour leading to involuntary admission (OR = 3.3). Predictors of aggressive behaviour can be useful to identify inpatients at risk. Nevertheless, additional situational determinants have to be recognized. Training for professionals should include preventive and de-escalating strategies to reduce the incidence of aggressive behaviour in psychiatric hospitals. The application of de-escalating interventions prior to admission might be effective in preventing aggressive behaviour during inpatient treatment especially for patients with severe mental disorders.

2010-08-01

The primary purpose of this longitudinal study was to examine, in a sample of Chinese children (initial M age = 8 years, N = 1,140), contributions of aggression to the development of social competence and academic achievement. Five waves of panel data on aggression and social and school performance were collected from peer evaluations, teacher ratings, and school records in Grades 2 to 5. Structural equation modeling revealed that aggression had unique effects on later social competence and academic achievement after their stabilities were controlled, particularly in the junior grades. Aggression also had significant indirect effects on social and academic outcomes through multiple pathways. Social competence and academic achievement contributed to the development of each other, but not aggression. The results indicate cascade effects of aggression in Chinese children from a developmental perspective.

Few studies have examined clinical correlates of aggression after first-time traumatic brain injury (TBI) within the first year after injury. The authors aimed to identify the rates of aggression at 6 and 12 months post-TBI and establish clinical and demographic correlates. A total of 103 subjects with first-time TBI were seen within 12 months postinjury and evaluated for aggression. Post-TBI social functioning and new-onset depression (within 3 months of the TBI) may serve as particularly important predictors for aggression within the first year of TBI, as these factors may afford intervention and subsequent decreased risk of aggression.

2017-01-01

Objective An analysis of airborne nicotine measurements collected in 49 low-income, multi-unit residences across the Greater Boston Area. Methods Nicotine concentrations were determined using passive monitors placed in homes over a one-week sampling period and air exchange rates (AER) were sampled using the perfluorocarbon tracer technique. Residents were surveyed through a questionnaire about smoking behaviour and a visual inspection was conducted to collect information on housing characteristics contributing to secondhand smoke (SHS) exposure. Using a mass balance model to account for the air exchange rate, volume of the home and sorption and re-emission of nicotine on indoor surfaces, the effective smoking rate (SReff) was determined for each residence. Results Nicotine levels ranged from the limit of detection to 26.92 µg/m3, with a mean of 2.20 µg/m3 and median of 0.13 µg/m3. Nicotine measurements were significantly associated with the number of smokers in the household and the number of cigarettes smoked in the home. The results of this study suggest that questionnaire reports can provide a valid estimate of residential exposure to tobacco smoke. In addition, this study found evidence that tobacco smoke contamination in low-income housing developments is not limited to homes with smokers (either residing in the home or visiting). The frequent report of tobacco smoke odour coming from other apartments or hallways resulted in increased levels of nicotine concentrations and SReff in non-smoking homes, suggestive of SHS infiltration from neighbouring units. Conclusion These findings have important implications for smoking regulations in multi-unit homes and highlight the need to reduce involuntary exposure to tobacco smoke among low-income housing residents.

2017-01-01

Using a risk-resilience framework, this study examined how varying levels of exposure to a natural disaster (EF-4 tornado) and children's characteristics (sex; anxiety) influenced the behavioral and psychological adjustment of children who shared a common risk factor predisaster (elevated aggression) prior to exposure through 1-year postdisaster. Participants included 360 children in Grades 4-6 (65% male; 78% African American) and their parents from predominantly low-income households who were already participating in a longitudinal study of indicated prevention effects for externalizing outcomes when the tornado occurred in 2011. Fourth-grade children who were screened for overt aggressive behavior were recruited in 3 annual cohorts (120 per year, beginning in 2009). Parent-rated aggression and internalizing problems were assessed prior to the tornado (Wave 1), within a half-year after the tornado (Wave 2), and at a 1-year follow-up (Wave 3). Children and parents rated their exposure to aspects of tornado-related traumatic experiences at Wave 3. Children displayed less reduction on aggression and internalizing problems if the children had experienced distress after the tornado or fears for their life, in combination with their pre-tornado level of anxiety. Higher levels of children's and parents' exposure to the tornado interacted with children's lower baseline child anxiety to predict less reduction in aggression and internalizing problems 1 year after the tornado. Higher levels of disaster exposure negatively affected at-risk children's level of improvement in aggression and internalizing problems, when life threat (parent- and child-reported) and child-reported distress after the tornado were moderated by baseline anxiety.

The present study examined sibling influence over reactive and proactive aggression in a sample of 452 same-sex twins (113 male dyads, 113 female dyads). Between and within siblings influence processes were examined as a function of relative levels of parental coercion and hostility to test the hypothesis that aggression contagion between twins occurs only among dyads who experience parental coerciveness. Teacher reports of reactive and proactive aggression were collected for each twin in kindergarten (M = 6.04 years; SD = 0.27) and in first grade (M = 7.08 years; SD = 0.27). Families were divided into relatively low, average, and relatively high parental coercion-hostility groups on the basis of maternal reports collected when the children were 5 years old. In families with relatively high levels of parental coercion-hostility, there was evidence of between-sibling influence, such that one twin’s reactive aggression at age 6 predicted increases in the other twin’s reactive aggression from ages 6 to 7, and one twin’s proactive aggression at age 6 predicted increases in the other twin’s proactive aggression from ages 6 to 7. There was also evidence of within-sibling influence such that a child’s level of reactive aggression at age 6 predicted increases in the same child’s proactive aggression at age 7, regardless of parental coercion-hostility. The findings provide new information about the etiology of reactive and proactive aggression and individual differences in their developmental interplay. PMID:25683448

International animal welfare organizations and federal, regional, and institutional oversight bodies encourage social housing of gregarious species, such as New Zealand white rabbits (Oryctolagus cuniculus), to promote animal wellbeing in research, teaching, testing and farming settings. At our institution, 2 groups of female New Zealand white rabbits (approximate age, 11 wk; mean weight, 2.35 kg), compatibly paired at the vendor for 5 wk, were paired in caging or group-housed in a floor pen. The rabbits appeared compatible, demonstrating primarily affiliative behaviors throughout 6 wk of daily observations. However, occult aggression that occurred between daily observations or nocturnally resulted in skin wounding. The skin injuries, first identified during prestudy clipping of fur from the back of each rabbit 6 wk after arrival, disqualified every animal from participation in skin toxicology and muscle implantation studies. Success meeting scientific research requirements while promoting animal welfare and health when socially housing New Zealand white rabbits requires examining the behavioral repertoire of their wild counterparts, European rabbits. Factors including age, sex, and housing density influence territoriality, dominance hierarchy, social ranking, and natural, agonistic, injurious, behavioral tendencies. IACUC and other relevant oversight bodies, researchers, and animal care staff should consider this case study and the species-specific natural history of New Zealand white rabbits when assessing the harm and benefit of social housing in regard to research utility and animal welfare.

Androgen levels, parenting styles and aggressive behavior in 5-6-year-old boys and girls. This study explores the relationship between androgen levels, parenting styles, and physical, verbal, and indirect aggression measures in 5-6-year-old children. 129 children (60 boys and 69 girls) were assessed in relation to their aggression levels using a peer-rating technique. Parents completed the Parenting Styles and Dimensions Questionnaire, from which the different parenting styles were obtained. Testosterone, androstenedione and dehydroepiandrosterone (DHEA) were measured using an enzymoimmunoassay technique in saliva samples. A regression analysis indicated that the directive mother-androstenedione interaction at the age of 5 was predictive of physical aggression at the age of 6. In specific terms, the results showed that, in boys with high androstenedione levels, directive maternal behavior is associated with physical aggression. The results are subsequently discussed in light of postulates related to parenting characteristic of developmental psychology and we suggest a potential link of our results with the hypothesis of maternal dominance.

The Hood River Passive Project was developed by Root Design Build of Hood River Oregon using the Passive House Planning Package (PHPP) to meet all of the requirements for certification under the European Passive House standards. The Passive House design approach has been gaining momentum among residential designers for custom homes and BEopt modeling indicates that these designs may actually exceed the goal of the U.S. Department of Energy's (DOE) Building America program to "reduce home energy use by 30%-50%" (compared to 2009 energy codes for new homes). This report documents the short term test results of the Shift Housemore » and compares the results of PHPP and BEopt modeling of the project. The design includes high R-Value assemblies, extremely tight construction, high performance doors and windows, solar thermal DHW, heat recovery ventilation, moveable external shutters and a high performance ductless mini-split heat pump. Cost analysis indicates that many of the measures implemented in this project did not meet the BA standard for cost neutrality. The ductless mini-split heat pump, lighting and advanced air leakage control were the most cost effective measures. The future challenge will be to value engineer the performance levels indicated here in modeling using production based practices at a significantly lower cost.« less

Recent advances in the treatment of cancer have focused on targeting genomic aberrations with selective therapeutic agents. In radioiodine resistant aggressive papillary thyroid cancers, there remain few effective therapeutic options. A 62-year-old man who underwent multiple operations for papillary thyroid cancer and whose metastases progressed despite standard treatments provided tumor tissue. We analyzed tumor and whole blood DNA by whole genome sequencing, achieving 80× or greater coverage over 94 % of the exome and 90 % of the genome. We determined somatic mutations and structural alterations. We found a total of 57 somatic mutations in 55 genes of the cancer genome. There was notably a lack of mutations in NRAS and BRAF, and no RET/PTC rearrangement. There was a mutation in the TRAPP oncogene and a loss of heterozygosity of the p16, p18, and RB1 tumor suppressor genes. The oncogenic driver for this tumor is a translocation involving the genes for anaplastic lymphoma receptor tyrosine kinase (ALK) and echinoderm microtubule associated protein like 4 (EML4). The EML4-ALK translocation has been reported in approximately 5 % of lung cancers, as well as in pediatric neuroblastoma, and is a therapeutic target for crizotinib. This is the first report of the whole genomic sequencing of a papillary thyroid cancer in which we identified an EML4-ALK translocation of a TRAPP oncogene mutation. These findings suggest that this tumor has a more distinct oncogenesis than BRAF mutant papillary thyroid cancer. Whole genome sequencing can elucidate an oncogenic context and expose potential therapeutic vulnerabilities in rare cancers.

How environmental and physiological signals interact to influence neural circuits underlying developmentally programmed social interactions such as male territorial aggression is poorly understood. We have tested the influence of sensory cues, social context, and sex hormones on progesterone receptor (PR)-expressing neurons in the ventromedial hypothalamus (VMH) that are critical for male territorial aggression. We find that these neurons can drive aggressive displays in solitary males independent of pheromonal input, gonadal hormones, opponents, or social context. By contrast, these neurons cannot elicit aggression in socially housed males that intrude in another male's territory unless their pheromone-sensing is disabled. This modulation of aggression cannot be accounted for by linear integration of environmental and physiological signals. Together, our studies suggest that fundamentally non-linear computations enable social context to exert a dominant influence on developmentally hard-wired hypothalamus-mediated male territorial aggression.

Whole-house mechanical ventilation is a critical component to a comprehensive strategy for good indoor air quality (IAQ). However, due to lack of integration with standard heating and cooling systems, and perceptions from a portion of the homebuilding industry about risks related to increased energy use, increased cost, and decreased comfort, voluntary and code-required adoption varies among regions. Smart ventilation controls (SVC) balance energy consumption, comfort, and IAQ by optimizing mechanical ventilation operation to reduce the heating and/or cooling loads, improve management of indoor moisture, and maintain IAQ equivalence according to ASHRAE 62.2.

Generalized aggressive periodontitis (GAgP) is a distinct type of periodontal disease associated with considerably more rapid periodontal tissue destruction than chronic periodontitis. This study presents the 5-year follow-up of a patient with GAgP. A 29-year-old man reported experiencing increasing gingival recession. He was treated using cause-related therapy, provisional splints, and flap surgery combined with allograft grafting and was followed up for 5 years. This case study shows that elimination of infectious microorganisms and meticulous long-term maintenance provide an effective treatment modality for aggressive periodontitis cases. This treatment modality can restore the masticatory function and provide the GAgP patient with improved quality of life.

Objectives Aggression and social tension among housemate cats is common and puts cats at risk of injury or relinquishment. The aim of this study was to evaluate the effectiveness of a new pheromone product in reducing aggression between housemate cats. Methods A new pheromone product (Feliway Friends) containing a proprietary cat-appeasing pheromone was evaluated for efficacy in reducing aggression between housemate cats via a randomized, double-blind, placebo-controlled pilot trial of 45 multi-cat households (pheromone [n = 20], placebo [n = 25]) reporting aggression for at least 2 weeks. Each household had 2-5 cats. Participants attended an educational training meeting on day (D) -7 and the veterinary behaviorist described behaviors to be monitored for 7 weeks using the Oakland Feline Social Interaction Scale (OFSIS), which assessed the frequency and intensity of 12 representative aggressive interactions. Participants were also provided with instructions for handling aggressive events, including classical conditioning, redirection by positive reinforcement and not punishing or startling the cat for aggressive displays. Punishment techniques were strongly discouraged. Plug-in diffusers with the pheromone product or placebo were utilized from D0-D28. Participants completed a daily diary of aggressive events and weekly OFSIS assessments through to D42. Results Evolution of the OFSIS-Aggression score according to treatment group in the full analysis set population revealed a significant effect on time and treatment group. The OFSIS-Aggression score decreased over time from D0-D28 in both groups (time factor P = 0.0001) with a significant difference in favor of the verum P = 0.06); similar results were found considering the D0-D42 period (time factor P = 0.0001 [D0] and P = 0.04 [D42]). Conclusions and relevance The OFSIS provided a quantifiable measure of the frequency and intensity of 12 inter-cat interactions reflecting conflict between cats. The cat

Intergenerational Transmission of Aggression in Romantic Relationships: The Moderating Role of Attachment Security

This prospective study used longitudinal, multi-reporter data to examine the influence of parents’ marital relationship functioning on subsequent adolescent romantic relationships. Consistent with Bryant and Conger’s model for the development of early adult romantic relationships (DEARR; 2002), we found that interactional styles, more specifically paternal aggression and satisfaction, exhibited in parents’ marital relationship when their adolescents were age 13, were predictive of qualities of the adolescent’s romantic relationships five years later. Continuities were domain specific: paternal satisfaction predicted adolescent satisfaction and paternal aggression predicted adolescent aggression. Attachment security moderated the link between paternal aggression and subsequent adolescent aggression, with continuities between negative conflictual styles across relationships reduced for secure adolescents. Results are interpreted as suggesting that attachment may help attenuated the transmission of destructive conflict strategies across generations. PMID:20001139

A sample of 10-12-year-olds selected for displaying aggressive behaviours was trained over three sessions to endorse benign rather than hostile attributions in response to ambiguous social scenarios. Compared to a test-retest control group (n = 18), children receiving CBM-I (n = 16) were less likely to endorse hostile attributions and more likely to endorse benign attributions in response to a new set of ambiguous social situations. Furthermore, aggressive behaviour scores reduced more in the trained group than in the untrained controls. Children who received attribution training also reported less perceived anger and showed a trend to report more self-control than those in the control group. Implications of these findings are discussed.

Objective Using a risk-resilience framework, this study examined how varying levels of exposure to a natural disaster (EF-4 tornado) and children’s characteristics (sex; anxiety) influenced the behavioral and psychological adjustment of children who shared a common risk factor predisaster (elevated aggression) prior to exposure through one-year postdisaster. Method Participants included 360 children in 4th–6th grades (65% male; 78% African American) and their parents from predominantly low-income households who were already participating in a longitudinal study of indicated prevention effects for externalizing outcomes when the tornado occurred in 2011. Fourth-grade children who were screened for overt aggressive behavior were recruited in three annual cohorts (120 per year, beginning in 2009). Parent-rated aggression and internalizing problems were assessed prior to the tornado (Wave 1), within a half-year after the tornado (Wave 2), and at a one-year follow-up (Wave 3). Children and parents rated their exposure to aspects of tornado-related traumatic experiences at Wave 3. Results Children displayed less reduction on aggression and internalizing problems if the children had experienced distress after the tornado or fears for their life, in combination with their pre-tornado level of anxiety. Higher levels of children’s and parents’ exposure to the tornado interacted with children’s lower baseline child anxiety to predict less reduction in aggression and internalizing problems one year after the tornado. Conclusion Higher levels of disaster exposure negatively affected at-risk children’s level of improvement in aggression and internalizing problems, when life threat (parent- and child-reported) and child-reported distress after the tornado were moderated by baseline anxiety.

On a Thermodynamic Approach to Material Selection for Service in Aggressive Multi-Component Gaseous and/or Vapor Environments

Glazoff, Michael Vasily; Marschman, Steven Craig; Soelberg, Nicholas Ray

This report fulfills the M4 milestone, M4FT-15IN08020110 UNF Analysis Support, under Work Package Number FT-15IN080201. The issue of materials selection for many engineering applications represents an important problem, particularly in cases where material failure is possible as a result of corrosive environments. For example, 304 dual purpose or 316 stainless steel is used in the construction of many used nuclear fuel storage canisters. Deployed all over the world, these canisters are housed inside shielded enclosures and cooled passively by convective airflow. When located along seaboards or particular industrial areas, salt, other corrosive chemicals, and moisture can become entrained in themore » air that cools the canisters. It is important to develop an understanding of what impact, if any, that chemical environment will have on those canisters. In many cases of corrosion in aggressive gaseous environments, the material selection process is based on some general recommendations, anecdotal evidence, and/or the past experience of that particular project’s participants. For gaseous mixtures, the theoretical basis is practically limited to the construction of the so-called “Ellingham diagrams” for pure metals. These plots predict the equilibrium temperature between different individual metals, their respective oxides, and oxygen gas. Similar diagrams can be constructed for the reactions with sulfur, nitrogen, carbon, etc. In the generalization of this approach by Richardson and Jeffes, additional scales can be superimposed upon an Ellingham diagram that would correspond to different gaseous mixtures, e.g. CO/CO 2, or H 2/H 2O. However, while the general approach to predicting the stability of a multi-component heterogeneous alloy (e.g., steel or a superalloy) in a multi-component aggressive gaseous environment was developed in very general form, actual examples of its applications to concrete real-life problems are practically absent.

Parents’ Aggressive Influences and Children's Aggressive Problem Solutions with Peers

PubMed Central

Duman, Sarah; Margolin, Gayla

2009-01-01

This study examined children's aggressive and assertive solutions to hypothetical peer scenarios in relation to parents’ responses to similar hypothetical social scenarios and parents’ actual marital aggression. The study included 118 9−10 year old children, and their mothers and fathers. Children's aggressive solutions correlated with same-sex parents’ actual marital aggression. For children with mothers who exhibit low actual marital aggression, mothers’ aggressive solutions to hypothetical situations corresponded with children's tendencies to propose aggressive but not assertive solutions. In a 3-way interaction, fathers’ aggressive solutions to peer scenarios and marital aggression, combined, exacerbated girls’ aggressive problem solving, but had the opposite effect for boys. Discussion addresses the complexity, particularly with respect to parent and child gender combinations, in understanding parents’ aggressive influences on children's peer relationships.

The purpose of this study was to evaluate the relationship between the number of periods children were exposed to familial homelessness and childhood aggression and victimization. Survey data were obtained from 4,297 fifth-grade children and their caregivers in three U.S. cities. Children and primary caregivers were surveyed longitudinally in 7th and 10th grades. Family homelessness, measured at each wave as unstable housing, was self-reported by the caregiver. Children were categorized into four mutually exclusive groups: victim only, aggressor only, victim-aggressor, and neither victim nor aggressor at each time point using validated measures. Multinomial, multilevel mixed models were used to evaluate the relationship among periods of homelessness and longitudinal victimization, aggression, and victim aggression compared to children who were nonvictims and nonaggressors. Results suggest that children who experienced family homelessness were more likely than domiciled children to report aggression and victim aggression but not victimization only. Multivariate analyses suggested that even brief periods of homelessness were positively associated with aggression and victim aggression (relative to neither) compared to children who were never homeless. Furthermore, childhood victimization and victim aggression significantly decreased from 5th grade to 10th grade while aggression significantly increased in 10th grade. Children who experienced family homelessness for brief periods of time were significantly more likely to be a victim-aggressor or aggressor compared to those who were never homeless. Prevention efforts should target housing security and other important factors that may reduce children's likelihood of aggression and associated victimization.

Youth worldwide play violent video games many hours per week. Previous research suggests that such exposure can increase physical aggression. We tested whether high exposure to violent video games increases physical aggression over time in both high- (United States) and low- (Japan) violence cultures. We hypothesized that the amount of exposure to violent video games early in a school year would predict changes in physical aggressiveness assessed later in the school year, even after statistically controlling for gender and previous physical aggressiveness. In 3 independent samples, participants' video game habits and physically aggressive behavior tendencies were assessed at 2 points in time, separated by 3 to 6 months. One sample consisted of 181 Japanese junior high students ranging in age from 12 to 15 years. A second Japanese sample consisted of 1050 students ranging in age from 13 to 18 years. The third sample consisted of 364 United States 3rd-, 4th-, and 5th-graders ranging in age from 9 to 12 years. RESULTS. Habitual violent video game play early in the school year predicted later aggression, even after controlling for gender and previous aggressiveness in each sample. Those who played a lot of violent video games became relatively more physically aggressive. Multisample structure equation modeling revealed that this longitudinal effect was of a similar magnitude in the United States and Japan for similar-aged youth and was smaller (but still significant) in the sample that included older youth. These longitudinal results confirm earlier experimental and cross-sectional studies that had suggested that playing violent video games is a significant risk factor for later physically aggressive behavior and that this violent video game effect on youth generalizes across very different cultures. As a whole, the research strongly suggests reducing the exposure of youth to this risk factor.

Arnocky, Steven; Vaillancourt, Tracy

2012-05-25

Adolescent peer-aggression has recently been considered from the evolutionary perspective of intrasexual competition for mates. We tested the hypothesis that peer-nominated physical aggression, indirect aggression, along with self-reported bullying behaviors at Time 1 would predict Time 2 dating status (one year later), and that Time 1 peer- and self-reported peer victimization would negatively predict Time 2 dating status. Participants were 310 adolescents who were in grades 6 through 9 (ages 11-14) at Time 1.  Results showed that for both boys and girls, peer-nominated indirect aggression was predictive of dating one year later even when controlling for age, peer-rated attractiveness, and peer-perceived popularity, as well as initial dating status. For both sexes, self-reported peer victimization was negatively related to having a dating partner at Time 2. Findings are discussed within the framework of intrasexual competition.

The effect of aggressive medical therapy on quantitative coronary plaque burden is not generally known, especially in ethnic Chinese. We reasoned that Cardiac CT could conveniently quantify early coronary atherosclerosis in our patient population, and hypothesized that serial observation could differentiate the efficacy of aggressive medical therapy regarding progression and regression of the atherosclerotic process, as well as evaluating the additional impact of life-style modification and the relative effects of the application of statin therapy. We employed a standardized Cardiac CT protocol to serially scan 113 westernized Hong Kong Chinese individuals (64 men and 49 women) with Chest Pain and positive coronary risk factors. In all cases included for this serial investigation, subsequent evaluation showed no significantly-obstructive coronary disease by functional studies and angiography. After stringent risk factor modification, including aggressive statin therapy to achieve LDL-cholesterol lowering conforming to N.C.E.P. ATP III guidelines, serial CT scans were performed 1-12 years apart for changes in coronary artery calcification (CAC), using the Agatston Score (AS) for quantification. At baseline, the mean AS was 1413.6 for males (mean age 54.4 years) and 2293.3 for females (mean age 62.4 years). The average increase of AS in the entire study population was 24% per year, contrasting with 16.4% per year on strict risk factor modification plus statin therapy, as opposed to 33.2% per year for historical control patients (p < 0.001). Additionally, 20.4% of the 113 patients demonstrated decreasing calcium scores. Medical therapy also yielded a remarkably low adverse event rate during the follow-up period --- 2 deaths, 2 strokes and only 1 case requiring PCI. This study revealed that aggressive medical therapy can positively influence coronary plaque aiding in serial regression of calcium scores.

2016-04-01

The aim of this study was to assess the reciprocal associations among social information processing (SIP) in dating conflicts and the perpetration of dating aggression. A first step involved the development of a measure (The Social Information Processing Questionnaire in Dating Conflicts, SIPQ-DC) to assess social information in scenarios of conflict with dating partners. A sample of 1,272 adolescents (653 girls, 619 boys; Mage = 14.74 years, SD = 1.21) completed measures of SIP and dating aggression perpetration in two different times, which were spaced 1 year apart. Confirmatory factor analyses provided support for a model with five correlated factors for the SIPQ-DC, namely, hostile attribution, anger, aggressive response access, anticipation of positive consequences for oneself, and anticipation of negative consequences for partners. Although the perpetration of dating aggression at T1 was cross-sectionally associated with all the SIP components, anger was the only component that predicted the residual increase in dating aggression behavior over time. The perpetration of dating aggression predicted a worsening of cognitive-emotional processes involved in dating conflicts. Some longitudinal paths were significant only in male adolescents. In conclusion, relationships among SIP and aggression are reciprocal. Gender differences in longitudinal paths can contribute to explaining men's higher perpetration of violence in adulthood. © The Author(s) 2014.

Young men's intimate partner violence and relationship functioning: long-term outcomes associated with suicide attempt and aggression in adolescence.

PubMed

Kerr, D C R; Capaldi, D M

2011-04-01

Longitudinal research supports that suicidal thoughts and behaviors in adolescence predict maladjustment in young adulthood. Prior research supports links between suicide attempt and aggression, perhaps because of a propensity for impulsive behavior in states of high negative affect that underlies both problems. Such vulnerability may increase risk for intimate partner violence and generally poor young adulthood relational adjustment. A total of 153 men participated in annual assessments from ages 10-32 years and with a romantic partner at three assessments from ages 18-25 years. Multi-method/multi-informant constructs were formed for parent/family risk factors, adolescent psychopathology (e.g. suicide-attempt history, mother-, father-, teacher- and self-reported physical aggression) and young adulthood relational distress (jealousy and low relationship satisfaction) and maladaptive relationship behavior (observed, self- and partner-reported physical and psychological aggression toward a partner, partner-reported injury, official domestic violence arrest records and relationship instability). Across informants, adolescent aggression was correlated with suicide-attempt history. With few exceptions, aggression and a suicide attempt in adolescence each predicted negative romantic relationship outcomes after controlling for measured confounds. Adolescent aggression predicted young adulthood aggression toward a partner, in part, via relationship dissatisfaction. Boys' aggression and suicide-attempt history in adolescence each predict poor relationship outcomes, including partner violence, in young adulthood. Findings are consistent with the theory of a trait-like vulnerability, such as impulsive aggression, that undermines adaptation across multiple domains in adolescence and young adulthood. Prevention and intervention approaches can target common causes of diverse public health problems.

Children's exposure to violent political conflict stimulates aggression at peers by increasing emotional distress, aggressive script rehearsal, and normative beliefs favoring aggression.

We examine the hypothesis that children's exposure to ethnic-political conflict and violence over the course of a year stimulates their increased aggression toward their own in-group peers in subsequent years. In addition, we examine what social cognitive and emotional processes mediate these effects and how these effects are moderated by gender, age, and ethnic group. To accomplish these aims, we collected three waves of data from 901 Israeli and 600 Palestinian youths (three age cohorts: 8, 11, and 14 years old) and their parents at 1-year intervals. Exposure to ethnic-political violence was correlated with aggression at in-group peers among all age cohorts. Using a cross-lagged structural equation model from Year 1 to Year 3, we found that the relation between exposure and aggression is more plausibly due to exposure to ethnic-political violence stimulating later aggression at peers than vice versa, and this effect was not moderated significantly by gender, age cohort, or ethnic group. Using three-wave structural equation models, we then showed that this effect was significantly mediated by changes in normative beliefs about aggression, aggressive script rehearsal, and emotional distress produced by the exposure. Again the best fitting model did not allow for moderation by gender, age cohort, or ethnic group. The findings are consistent with recent theorizing that exposure to violence leads to changes both in emotional processes promoting aggression and in the acquisition through observational learning of social cognitions promoting aggression.

Partner aggression in high-risk families from birth to age 3 years: associations with harsh parenting and child maladjustment.

PubMed

Graham, Alice M; Kim, Hyoun K; Fisher, Philip A

2012-02-01

Aggression between partners represents a potential guiding force in family dynamics. However, research examining the influence of partner aggression (physically and psychologically aggressive acts by both partners) on harsh parenting and young child adjustment has been limited by a frequent focus on low-risk samples and by the examination of partner aggression at a single time point. Especially in the context of multiple risk factors and around transitions such as childbirth, partner aggression might be better understood as a dynamic process. In the present study, longitudinal trajectories of partner aggression from birth to age 3 years in a large, high-risk, and ethnically diverse sample (N = 461) were examined. Specific risk factors were tested as predictors of aggression over time, and the longitudinal effects of partner aggression on maternal harsh parenting and child maladjustment were examined. Partner aggression decreased over time, with higher maternal depression and lower maternal age predicting greater decreases in partner aggression. While taking into account contextual and psychosocial risk factors, higher partner aggression measured at birth and a smaller decrease over time independently predicted higher levels of maternal harsh parenting at age 3 years. Initial level of partner aggression and change over time predicted child maladjustment indirectly (via maternal harsh parenting). The implications of understanding change in partner aggression over time as a path to harsh parenting and young children's maladjustment in the context of multiple risk factors are discussed.

Childhood aggression and its resulting consequences inflict a huge burden on affected children, their relatives, teachers, peers and society as a whole. Aggression during childhood rarely occurs in isolation and is correlated with other symptoms of childhood psychopathology. In this paper, we aim to describe and improve the understanding of the co-occurrence of aggression with other forms of childhood psychopathology. We focus on the co-occurrence of aggression and other childhood behavioural and emotional problems, including other externalising problems, attention problems and anxiety-depression. The data were brought together within the EU-ACTION (Aggression in Children: unravelling gene-environment interplay to inform Treatment and InterventiON strategies) project. We analysed the co-occurrence of aggression and other childhood behavioural and emotional problems as a function of the child's age (ages 3 through 16 years), gender, the person rating the behaviour (father, mother or self) and assessment instrument. The data came from six large population-based European cohort studies from the Netherlands (2x), the UK, Finland and Sweden (2x). Multiple assessment instruments, including the Child Behaviour Checklist (CBCL), the Strengths and Difficulties Questionnaire (SDQ) and Multidimensional Peer Nomination Inventory (MPNI), were used. There was a good representation of boys and girls in each age category, with data for 30,523 3- to 4-year-olds (49.5% boys), 20,958 5- to 6-year-olds (49.6% boys), 18,291 7- to 8-year-olds (49.0% boys), 27,218 9- to 10-year-olds (49.4% boys), 18,543 12- to 13-year-olds (48.9% boys) and 10,088 15- to 16-year-olds (46.6% boys). We replicated the well-established gender differences in average aggression scores at most ages for parental ratings. The gender differences decreased with age and were not present for self-reports. Aggression co-occurred with the majority of other behavioural and social problems, from both externalising and

AUTONOMY AND RELATEDNESS IN MOTHER-TEEN INTERACTIONS AS PREDICTORS OF INVOLVEMENT IN ADOLESCENT DATING AGGRESSION.

Niolon, Phyllis Holditch; Kuperminc, Gabriel P; Allen, Joseph P

2015-04-01

This multi-method, longitudinal study examines the negotiation of autonomy and relatedness between teens and their mothers as etiologic predictors of perpetration and victimization of dating aggression two years later. Observations of 88 mid-adolescents and their mothers discussing a topic of disagreement were coded for each individual's demonstrations of autonomy and relatedness using a validated coding system. Adolescents self-reported on perpetration and victimization of physical and psychological dating aggression two years later. We hypothesized that mother's and adolescents' behaviors supporting autonomy and relatedness would longitudinally predict lower reporting of dating aggression, and that their behaviors inhibiting autonomy and relatedness would predict higher reporting of dating aggression. Hypotheses were not supported; main findings were characterized by interactions of sex and risk status with autonomy. Maternal behaviors supporting autonomy predicted higher reports of perpetration and victimization of physical dating aggression for girls, but not for boys. Adolescent behaviors supporting autonomy predicted higher reports of perpetration of physical dating aggression for high-risk adolescents, but not for low-risk adolescents. Results indicate that autonomy is a dynamic developmental process, operating differently as a function of social contexts in predicting dating aggression. Examination of these and other developmental processes within parent-child relationships is important in predicting dating aggression, but may depend on social context.

Assessing the whole-body absorption in a human in a realistic environment requires a statistical approach covering all possible exposure situations. This article describes the development of a statistical multi-path exposure method for heterogeneous realistic human body models. The method is applied for the 6-year-old Virtual Family boy (VFB) exposed to the GSM downlink at 950 MHz. It is shown that the whole-body SAR does not differ significantly over the different environments at an operating frequency of 950 MHz. Furthermore, the whole-body SAR in the VFB for multi-path exposure exceeds the whole-body SAR for worst-case single-incident plane wave exposure by 3.6%. Moreover, the ICNIRP reference levels are not conservative with the basic restrictions in 0.3% of the exposure samples for the VFB at the GSM downlink of 950 MHz. The homogeneous spheroid with the dielectric properties of the head suggested by the IEC underestimates the absorption compared to realistic human body models. Moreover, the variation in the whole-body SAR for realistic human body models is larger than for homogeneous spheroid models. This is mainly due to the heterogeneity of the tissues and the irregular shape of the realistic human body model compared to homogeneous spheroid human body models.

The incidence of oligometastases to the brain in good performance status patients is increasing due to improvements in systemic therapy and MRI screening, but specific management pathways are often lacking. We established a multi-disciplinary brain metastases clinic with specific referral guidelines and standard follow-up for good prognosis patients with the view that improving the process of care may improve outcomes. We evaluated patient demographic and outcome data for patients first seen between February 2007 and November 2011. The clinic was feasible to run and referrals were appropriate. 87% of patients referred received a localised therapy during their treatment course. 114 patients were seen and patient numbers increased during the 5 years that the clinic has been running as relationships between clinicians were developed. Median follow-up for those still alive was 23.1 months (6.1-79.1 months). Primary treatments were: surgery alone 52%, surgery plus whole brain radiotherapy (WBRT) 9%, radiosurgery 14%, WBRT alone 23%, supportive care 2%. 43% received subsequent treatment for brain metastases. 25%, 11% and 15% respectively developed local neurological progression only, new brain metastases only or both. Median overall survival following brain metastases diagnosis was 16.0 months (range 1-79.1 months). Breast (32%) and NSCLC (26%) were the most common primary tumours with median survivals of 26 and 16.9 months respectively (HR 0.6, p=0.07). Overall one year survival was 55% and two year survival 31.5%. 85 patients died of whom 37 (44%) had a neurological death. Careful patient selection and multi-disciplinary management identifies a subset of patients with oligometastatic brain disease who benefit from aggressive local treatment. A dedicated joint neurosurgical/ neuro-oncology clinic for such patients is feasible and effective. It also offers the opportunity to better define management strategies and further research in this field. Consideration should be

Bidirectional Associations between Peer Victimization and Functions of Aggression in Middle Childhood: Further Evaluation across Informants and Academic Years.

Cooley, John L; Fite, Paula J; Pederson, Casey A

2018-01-01

The current 3-wave study examined bidirectional associations between peer victimization and functions of aggression across informants over a 1-year period in middle childhood, with attention to potential gender differences. Participants included 198 children (51% girls) in the third and fourth grades and their homeroom teachers. Peer victimization was assessed using both child- and teacher-reports, and teachers provided ratings of reactive and proactive aggression. Cross-classified multilevel cross-lagged models indicated that child-reports, but not teacher-reports, of peer victimization predicted higher levels of reactive aggression within and across academic years. Further, reactive aggression predicted subsequent increases in child- and teacher-reports of peer victimization across each wave of data. Several gender differences, particularly in the crossed paths between proactive aggression and peer victimization, also emerged. Whereas peer victimization was found to partially account for the stability of reactive aggression over time, reactive aggression did not account for the stability of peer victimization. Taken together with previous research, the current findings suggest that child-reports of peer victimization may help identify youth who are risk for exhibiting increased reactive aggression over time. Further, they highlight the need to target reactively aggressive behavior for the prevention of peer victimization in middle childhood.

Biomarkers to Distinguish Aggressive Cancers from Non-aggressive or Non-progressing Cancer — EDRN Public Portal

Cancer.gov

Distinguishing aggressive cancers from non-aggressive or non-progressing cancers is an issue of both clinical and public health importance particularly for those cancers with an available screening test. With respect to breast cancer, mammographic screening has been shown in randomized trials to reduce breast cancer mortality, but given the limitations of its sensitivity and specificity some breast cancers are missed by screening. These so called interval detected breast cancers diagnosed between regular screenings are known to have a more aggressive clinical profile. In addition, of those cancers detected by mammography some are indolent while others are more likely to recur despite treatment. The pilot study proposed herein is highly responsive to the EDRN supplement titled “Biomarkers to Distinguish Aggressive Cancers from Nonaggressive or Non-progressing Cancers” in that it addresses both of the research objectives related to these issues outlined in the notice for this supplement: Aim 1: To identify biomarkers in tumor tissue related to risk of interval detected vs. mammography screen detected breast cancer focusing on early stage invasive disease. We will compare gene expression profiles using the whole genome-cDNA-mediated Annealing, Selection, extension and Ligation (DASL) assay of 50 screen detected cancers to those of 50 interval detected cancers. Through this approach we will advance our understanding of the molecular characteristics of interval vs. screen detected breast cancers and discover novel biomarkers that distinguish between them. Aim 2: To identify biomarkers in tumor tissue related to risk of cancer recurrence among patients with screen detected early stage invasive breast cancer. Using the DASL assay we will compare gene expression profiles from screen detected early stage breast cancer that either recurred within five years or never recurred within five years. These two groups of patients will be matched on multiple factors including

OBJECTIVE To examine the association between maternal use of corporal punishment (CP) against their 3-year-old children and subsequent aggressive behavior among those children two years later. METHODS Respondents participated in waves 1, 3, and 5 of the Fragile Families and Child Wellbeing Study (1998–2005), a population-based longitudinal birth cohort study of children (and their parents) born in one of 20 large U.S. cities (n=2,461), with oversampling of unmarried couples. Maternal reports of CP, children’s aggressive behaviors at 3 and 5 years of age, and a host of key demographics and potential confounding factors were assessed including: child physical maltreatment, psychological maltreatment, and neglect, intimate partner aggression and violence, and maternal stress, depression, substance use, and consideration of abortion. RESULTS Multiple logistic regression analyses revealed that frequent use of CP (i.e., maternal use of spanking more than twice in the prior month) when the child was 3 years-old was associated with increased risk for higher levels of child aggression when the child was 5 years-old (adjusted odds ratio = 1.49 [CI=1.2–1.8] p<0.0001), even after simultaneously controlling for the child’s level of aggression at 3 years of age as well as all of the aforementioned confounding factors and key demographics. CONCLUSIONS Despite American Academy of Pediatrics recommendations to the contrary, most parents in the U.S. approve of and have used CP as a form of child discipline. The current findings support a growing body of evidence that even minor forms of CP, such as spanking, raise risk for increased subsequent child aggressive behavior. Importantly, these findings cannot be attributed to the possible confounding effects of a host of other maternal parenting risk factors. Increased and improved efforts to reduce the use of CP and promote the use of alternative, effective non-physical forms of child discipline among U.S. parents are warranted

Adolescents' aggressive behavior is a growing social problem with important implications for psychosocial adjustment. The teaching of emotional skills has an important impact on reducing aggression in schools. However, little scientific evidence has shown the explanatory mechanism through which this training reduces aggression during adolescence. This article aims to provide evidence for the effectiveness of a 3-year longitudinal intervention among adolescents in nine Spanish schools. A total of 476 adolescents participated. Results showed a reduction in physical and verbal aggression in Time 2 through the reduction in negative affect, anger, and hostile feelings, compared with an active control group. The training seems to be crucial for dealing with the emotional and cognitive components of aggression and, thus, their behavioral manifestations. © 2017 The Authors.

Because zoos typically house animals for extended periods of time, longitudinal studies can play an important role in evaluating and optimizing animal care and management. For example, information on patterns of aggression and mating behavior across years can be used to monitor well-being, assess response to changes to group composition, and promote successful reproduction. Here, we report on patterns of aggression and pair bonding by American flamingos (Phoenicopterus ruber) at the Audubon Zoo, New Orleans USA across 4 years (2012-2015), a period that included a simultaneous introduction and removal of individuals in 2014. At the population level, overall rates and social network indices of aggressive interactions were relatively stable over the study period, without a strong signal of the 2014 replacement event. At the individual level, flamingos exhibited a high degree of within-individual consistency in levels of aggression initiated (W = 0.530, P < 0.001), and received (W = 0.369, P = 0.042). In terms of pair bonds, females re-paired with the same individuals across years more frequently (between 58% and 100% from year to year) than they switched mates, and no bonds were established between pre-existing and introduced individuals. These findings indicate a high degree of stability in aggression and pair bonding behavior in this population of captive flamingos, at both the population and individual level. Longitudinal studies such as this one provide an opportunity to better our understanding of flamingos and other long-lived, group-living animals along with their management needs, especially in terms of maintaining social cohesion in captivity and improving captive breeding programs. © 2016 Wiley Periodicals, Inc.

The neurotransmitter serotonin (5-HT) has been linked to the underlying biological processes related to aggressive behaviour. However, only a few studies on this subject involving young people have been published so far. We aimed to investigate the effects of acute tryptophan depletion (ATD) on reactive aggression and decision-time for aggressive responses in a sample of young people with Attention deficit hyperactivity disorder (n = 20), a population at risk for aggressive behaviour. The study design was a double-blind within-subject crossover design. Aggression was assessed using a Point subtraction aggression game (PSAG) with high (HP) and low provocation (LP) trials 2.5 h after the intake of ATD and a tryptophan-balanced control condition. A chi-square comparison was used to identify the effect of ATD on increased aggression after LP. Boys were more likely to respond with an increased aggressive response after HP under ATD as represented by an increased relative risk and odds ratios. Girls had a higher relative risk than boys of an increased point subtraction under ATD after LP. No significant gender differences in decision-time were detected. An effect of ATD on increased aggression was found in the whole sample after LP. Research involving larger samples is needed to confirm the present preliminary findings. © 2012 John Wiley & Sons A/S.

2012-01-01

This study assessed girls’ and boys’ dominance-related behaviors (aggressive, commanding, submissive, and neutral behaviors) as they naturally occurred during interactions with male and female peers and evaluated the possibility that such behaviors elicit aggression from peers. Using a focal observational procedure, young girls’ and boys’ (N = 170; 54% boys) naturally occurring dominance-related behaviors and male and female peers’ aggressive responses to those behaviors were recorded multiple times each week across the academic year. Findings suggested that same-gender aggression occurred at similar rates as other-gender aggression once tendencies toward gender segregated play were controlled. Additionally, there were both gender-based similarities and differences in children’s use of dominance-related behaviors in peer interactions and as antecedents for peers’ aggression. The findings have implications for the literatures on aggression and gendered peer interactions. PMID:22369337

We investigated the reliability and (convergent and discriminant) validity of an observational measure of physical aggression in toddlers and preschoolers, originally developed by Keenan and Shaw [1994]. The observation instrument is based on a developmental definition of aggression. Physical aggression was observed twice in a laboratory setting, the first time when children were 1-3 years old, and again 1 year later. Observed physical aggression was significantly related to concurrent mother-rated physical aggression for 2- to 4-year-olds, but not to maternal ratings of nonaggressive externalizing problems, indicating the measure's discriminant validity. However, we did not find significant 1-year stability of observed physical aggression in any of the age groups, whereas mother-rated physical aggression was significantly stable for all ages. The observational measure shows promise, but may have assessed state rather than trait aggression in our study. Copyright 2008 Wiley-Liss, Inc.

Considerable research has investigated the deleterious effects of teachers responding aggressively to students who misbehave, but the mechanism underlying this dysfunctional behaviour remains unknown. This study investigated whether the mechanism underlying teacher aggression follows I 3 theory or General Aggression Model (GAM) metatheory of human aggression. I 3 theory explains exceptional, catastrophic events of human aggression, whereas the GAM explains common human aggression behaviours. A total of 249 Australian teachers participated in this study, including 142 primary school teachers (Mdn [age] = 35-39 years; Mdn [years teaching] = 10-14 years; 84% female) and 107 secondary school teachers (Mdn [age] = 45-49 years; Mdn [years teaching] = 15-19 years; 65% female). Participants completed four online self-report questionnaires, which assessed caregiving responsiveness, trait self-control, misbehaviour provocation, and teacher aggression. Analyses revealed that the GAM most accurately captures the mechanism underlying teacher aggression, with lower caregiving responsiveness appearing to indirectly lead to teacher aggression via higher misbehaviour provocation and lower trait self-control in serial, controlling for gender, age, years teaching, and current role (primary, secondary). This study indicates that teacher aggression proceeds from 'the person in the situation'. Specifically, lower caregiving responsiveness appears to negatively shape a teacher's affective, cognitive, and arousal states, which influence how they perceive and interpret student misbehaviour. These internal states, in turn, appear to negatively influence appraisal and decision processes, leading to immediate appraisal and impulsive actions. These results raise the possibility that teacher aggression is a form of countertransference. © 2017 The British Psychological Society.

International studies show that aggressive behavior against primary care physicians is not an uncommon occurrence. There has been no systematic study to date of the nature and frequency of such occurrences in Germany. A four-page questionnaire was sent to a nationwide random sample of 1500 primary care physicians. It contained questions about the type, frequency, severity, and site of aggressive behavior against the physician. 831 (59%) of 1408 correctly delivered questionnaires could be included in the analysis. 91% of the respondents (95% confidence interval [CI], 89%-93%) said they had been the object of aggressive behavior at some time in their career as a primary care physician, 73% (95% CI, 70%-76%) in the previous 12 months. Severe aggression or violence had been experienced by 23% (95% CI, 20%-25%) in their entire career and 11% (95% CI, 8%-13%) in the previous year. The vast majority of respondents said they felt safe in their offices. 66% of female and 34% of male respondents said they did not feel safe making house visits while on on-call duty. The frequency and extent of aggression and violence against primary care physicians in Germany is comparable to those reported by international studies. Strategies for dealing with this problem should be developed. In particular, the issue of safety on emergency call needs to be addressed.

Drawing on the framework of social domain theory, this multi-method, multi-informant longitudinal study examined whether callous-unemotional (CU) tendencies moderated the association between U.S. 4 to 7 year olds' (n = 135; Mage = 5.65, 50% male; 75% White) ability to differentiate hypothetical, prototypical moral and conventional transgressions along theoretical criteria and teacher (n = 49) and parent (n = 128, 91% mothers) ratings of physical aggression. Deficits in domain distinction ability were associated with greater teacher-reported aggression both concurrently and 9 months later, but only for children high in CU traits. No main effects or interactions were found for parent reports. These findings build on a growing body of research demonstrating that children who use aggression in a deliberate and callous manner show deficits in their basic understanding of moral norms.

Objective This multi-method, longitudinal study examines the negotiation of autonomy and relatedness between teens and their mothers as etiologic predictors of perpetration and victimization of dating aggression two years later. Method Observations of 88 mid-adolescents and their mothers discussing a topic of disagreement were coded for each individual’s demonstrations of autonomy and relatedness using a validated coding system. Adolescents self-reported on perpetration and victimization of physical and psychological dating aggression two years later. We hypothesized that mother’s and adolescents’ behaviors supporting autonomy and relatedness would longitudinally predict lower reporting of dating aggression, and that their behaviors inhibiting autonomy and relatedness would predict higher reporting of dating aggression. Results Hypotheses were not supported; main findings were characterized by interactions of sex and risk status with autonomy. Maternal behaviors supporting autonomy predicted higher reports of perpetration and victimization of physical dating aggression for girls, but not for boys. Adolescent behaviors supporting autonomy predicted higher reports of perpetration of physical dating aggression for high-risk adolescents, but not for low-risk adolescents. Conclusions Results indicate that autonomy is a dynamic developmental process, operating differently as a function of social contexts in predicting dating aggression. Examination of these and other developmental processes within parent-child relationships is important in predicting dating aggression, but may depend on social context. PMID:25914852

Little attention has been paid to the motivation to respond to provocation and to the interaction between this motivation, alcohol, the drinking environment, and individual characteristics. Undergraduates at six Canadian universities (N = 1,232) read three vignettes describing conflict situations with social environmental manipulations while imagining themselves as either sober or intoxicated. Self-ratings assessed likelihood of assertive and aggressive responses and motivational indices of anger, offensiveness of the instigator's actions, and importance to respond to the provocation. Respondents also completed a measure of trait aggression. Multi-group structural equation models supported the hypothesis that perceived likelihood of reactive aggression is influenced by perceived alcohol intoxication, gender, trait aggression, social environmental factors, and motivation to respond to the provocation. In addition, a number of interactions were found among the predictors. These results provide insight into the types of factors that may influence aggression in drinking situations.

This study had two aims. The first was to assess and compare various types of aggressive behavior toward others reported by borderline patients and axis II comparison subjects over time. The second was to determine the best baseline and time-varying predictors of aggressive behavior in these borderline patients. At baseline, a series of interviews and self-report measures were administered to 290 borderline patients and 72 axis II comparison subjects. Measures assessing aggression toward others, axis I and II disorders as well as adult adversity were re-administered every two years over the course of ten years. It was found that borderline patients reported significantly higher rates of verbal, emotional, and physical aggression toward others than comparison subjects but the rates of these forms of aggression toward others declined significantly for those in both study groups. Multivariate analyses indicated that the strongest predictors of adult aggression towards others were severity of adult adversity and a substance use disorder. Taken together, these results suggest that borderline patients commonly report aggression toward others but that this aggression declines significantly over time. These results also suggest that this aggression toward others is most strongly associated with adult experiences of adversity and concurrent substance abuse. Copyright © 2017 Elsevier Ireland Ltd.

Endogenous Price Bubbles in a Multi-Agent System of the Housing Market

PubMed Central

2015-01-01

Economic history shows a large number of boom-bust cycles, with the U.S. real estate market as one of the latest examples. Classical economic models have not been able to provide a full explanation for this type of market dynamics. Therefore, we analyze home prices in the U.S. using an alternative approach, a multi-agent complex system. Instead of the classical assumptions of agent rationality and market efficiency, agents in the model are heterogeneous, adaptive, and boundedly rational. We estimate the multi-agent system with historical house prices for the U.S. market. The model fits the data well and a deterministic version of the model can endogenously produce boom-and-bust cycles on the basis of the estimated coefficients. This implies that trading between agents themselves can create major price swings in absence of fundamental news. PMID:26107740

With the frequent occurrence of campus violence, scholars have devoted increasing attention to college students' aggression. This study aims to estimate the prevalence of aggression in Chinese university students and identify factors that could influence their aggression. We can thus find methods to reduce the incidence of college students' aggression in the future. A multi-stage stratified sampling procedure was used to select university students (N = 4565) aged 16-25 years in Harbin. The Aggression Questionnaire, the Adolescent Self-Rating Life Events Checklist and the Social Support Revalued Scale were used to collect data. Females reported lower levels of aggression than males (p < .001). A multiple linear regression analysis was conducted to determine the influence of factors of aggression, and the model was highly significant (R 2  = .233, Ad R 2  = .230, p < .01). The results show that the aggression is affected by gender, family-level and school-level variables. Aggression scores are significantly correlated with not only family-level or school-level variables independently, but their combination as well. We find that the risk factors for aggression include a dissatisfying profession, higher levels of study pressure, poor parental relationships, poor interpersonal relationships, the presence of siblings, punishment, health maladjustment, less subjective support, and lower levels of utilization of social support.

Agreeableness and alcohol-related aggression: the mediating effect of trait aggressivity.

Miller, Cameron A; Parrott, Dominic J; Giancola, Peter R

2009-12-01

This study investigated the mediating effect of trait aggressivity on the relation between agreeableness and alcohol-related aggression in a laboratory setting. Participants were 116 healthy male social drinkers between 21 and 30 years of age. Agreeableness and trait aggressivity were measured using the Big Five Inventory and the Buss-Perry Aggression Questionnaire, respectively. Following the consumption of an alcohol or no-alcohol control beverage, participants completed a modified version of the Taylor Aggression Paradigm, in which electric shocks were received from and administered to a fictitious opponent during a competitive task. Aggression was operationalized as the proportion of the most extreme shocks delivered to the fictitious opponent under conditions of low and high provocation. Results indicated that lower levels of agreeableness were associated with higher levels of trait aggressivity. In turn, higher levels of trait aggressivity predicted extreme aggression in intoxicated, but not sober, participants under low, but not high, provocation. Findings highlight the importance of examining determinants of intoxicated aggression within a broader theoretical framework of personality.

A developmental cascade model was tested to examine longitudinal associations among firstborn children’s aggression, Theory-of-Mind, and antagonism toward their younger sibling during the first year of siblinghood. Aggression and Theory-of-Mind were assessed before the birth of a sibling, and 4 and 12 months after the birth, and antagonism was examined at 4 and 12 months in a sample of 208 firstborn children (initial M age = 30 months, 56% girls) from primarily European American, middle- class families. Firstborns’ aggression consistently predicted high sibling antagonism both directly and through poorer Theory-of-Mind. Results highlight the importance of examining longitudinal influences across behavioral, social-cognitive, and relational factors that are closely intertwined even from the early years of life.

Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed in Barcelona Zoo. The 2-year study presented in this article examined the effects of introducing changes in the exhibit of the drill to improve his welfare by analyzing scan behaviors. First, a partial visual barrier was applied and proved to be insufficient to decrease the long-term stress indicators assessed. Next, a feeding enrichment program was implemented. The results supported the hypothesis that feeding and explorative activities would increase, whereas apathetic and stereotypic behaviors would decrease. However, visitor-directed aggression did not vary, indicating that more profound structural modifications were needed to reduce the negative impact of the agonistic interactions between the drill and the public. The study emphasized the usefulness of environmental enrichment evaluations in assessing captive animal welfare.

This study assessed the prevalence, clinical characteristics, and demographics of chronic and aggressive periodontitis in a representative sample drawn from a subpopulation in Morocco. Eight hundred and thirty students representative of 12+ years old attending schools in the Province of Benslimane, Morocco were selected by a multi-phased, probability sampling. Their age was 12-25 years (mean: 16.1 years) and comprised of 50% males and 50% females. Chronic and aggressive periodontitis were determined clinically. A total of 31% and 10.1% of the subjects had ≥4 mm and ≥6 mm attachment loss, respectively; 4.9% had aggressive periodontitis, and 6.4% had chronic periodontitis. Subjects with chronic periodontitis typically had 4-5 mm attachment loss affecting a few molars or premolars. Subjects with aggressive periodontitis had ≥5 mm attachment loss affecting multiple teeth, and 68% and 73% of these subjects had ≥6 mm attachment loss affecting maxillary and mandibular molars respectively. Attachment loss and periodontitis were significantly more prevalent in the 19-25 years group, than the 12-18 years age group. There were no significant differences in disease prevalence by gender or ethnic groups (Arab versus Berber). This young Moroccan population is at high risk of destructive periodontal disease, and further studies are indicated to investigate the biological and environmental factors that may contribute to the increased risk of disease in this population. © 2016 John Wiley & Sons A/S.

Introduction Housing First is a complex housing and support intervention for homeless individuals with mental health problems. It has a sufficient knowledge base and interest to warrant a test of wide-scale implementation in various settings. This protocol describes the quantitative design of a Canadian five city, $110 million demonstration project and provides the rationale for key scientific decisions. Methods A pragmatic, mixed methods, multi-site field trial of the effectiveness of Housing First in Vancouver, Winnipeg, Toronto, Montreal and Moncton, is randomising approximately 2500 participants, stratified by high and moderate need levels, into intervention and treatment as usual groups. Quantitative outcome measures are being collected over a 2-year period and a qualitative process evaluation is being completed. Primary outcomes are housing stability, social functioning and, for the economic analyses, quality of life. Hierarchical linear modelling is the primary data analytic strategy. Ethics and dissemination Research ethics board approval has been obtained from 11 institutions and a safety and adverse events committee is in place. The results of the multi-site analyses of outcomes at 12 months and 2 years will be reported in a series of core scientific journal papers. Extensive knowledge exchange activities with non-academic audiences will occur throughout the duration of the project. Trial registration number This study has been registered with the International Standard Randomised Control Trial Number Register and assigned ISRCTN42520374. PMID:22102645

Improving Comfort in Hot-Humid Climates with a Whole-House Dehumidifier, Windermere, Florida (Fact Sheet)

DOE Office of Scientific and Technical Information (OSTI.GOV)

2013-11-01

Maintaining comfort in a home can be challenging in hot-humid climates. At the common summer temperature set point of 75 degrees F, the perceived air temperature can vary by 11 degrees F because higher indoor humidity reduces comfort. Often the air conditioner (AC) thermostat set point is lower than the desirable cooling level to try to increase moisture removal so that the interior air is not humid or "muggy." However, this method is not always effective in maintaining indoor relative humidity (RH) or comfort. In order to quantify the performance of a combined whole-house dehumidifier (WHD) AC system, researchers frommore » the U.S. Department of Energy's Building America team Consortium of Advanced Residential Buildings (CARB) monitored the operation of two Lennox AC systems coupled with a Honeywell DH150 TrueDRY whole-house dehumidifier for a six-month period. By using a WHD to control moisture levels (latent cooling) and optimizing a central AC to control temperature (sensible cooling), improvements in comfort can be achieved while reducing utility costs. Indoor comfort for this study was defined as maintaining indoor conditions at below 60% RH and a humidity ratio of 0.012 lbm/lbm while at common dry bulb set point temperatures of 74 degrees -80 degrees F. In addition to enhanced comfort, controlling moisture to these levels can reduce the risk of other potential issues such as mold growth, pests, and building component degradation. Because a standard AC must also reduce dry bulb air temperature in order to remove moisture, a WHD is typically needed to support these latent loads when sensible heat removal is not desired.« less

The impact of classroom aggression on the development of aggressive behavior problems in children

PubMed Central

Thomas, Duane E.; Bierman, Karen L.

2009-01-01

Prior research suggests that exposure to elementary classrooms characterized by high levels of student aggression may contribute to the development of child aggressive behavior problems. To explore this process in more detail, this study followed a longitudinal sample of 4,907 children and examined demographic factors associated with exposure to high-aggression classrooms, including school context factors (school size, student poverty levels, and rural vs. urban location) and child ethnicity (African American, European American). The developmental impact of different temporal patterns of exposure (e.g., primacy, recency, chronicity) to high-aggression classrooms was evaluated on child aggression. Analyses revealed that African American children attending large, urban schools that served socioeconomically disadvantaged students were more likely than other students to be exposed to high-aggressive classroom contexts. Hierarchical regressions demonstrated cumulative effects for temporal exposure, whereby children with multiple years of exposure showed higher levels of aggressive behavior after 3 years than children with primacy, less recent, and less chronic exposure, controlling for initial levels of aggression. Implications are discussed for developmental research and preventive interventions. PMID:16600064

National report on aggressions to physicians in Spain 2010-2015: violence in the workplace-ecological study.

PubMed

2018-06-04

Aggressions against health staff is a phenomenon that is not widely studied worldwide. To date, there is no national study analyzing this situation in Spain. Our objective is to describe and analyze aggressions to physicians of the whole Spanish territory in the period 2010-2015, through an observational analytical study by conglomerates (ecological) with all aggressions to physicians identified by the 52 official medical associations of Spain over 6 years of study. There were 2419 aggressions on physicians, 51% on men. Primary care is the area that concentrates more incidents (54%) and the public sector is the most affected (89%). A third of the assaults were concentrated on professionals aged 46-55 years old. Cumulative incidence decreased from 20 aggressions × 10,000 physicians in 2010 to 15 × 10,000 physicians in 2015. The importance and seriousness of the problem of aggressions against physicians is verified through notifications to the registry. The collection method is different from others based on surveys, and therefore the figures are significantly lower than other studies. The scant denunciation by attacked physicians in Spain makes deceiving the real dimensions of the phenomenon.

The objective of this study was to examine associations between maternal and paternal use of corporal punishment (CP) for 3-year-old children and intimate partner aggression or violence (IPAV) in a population-based sample. The study sample (N=1997) was derived from wave 3 of the Fragile Families and Child Wellbeing Study. Mother and father reports regarding their use of CP and their IPAV victimization were analyzed. IPAV included coercion and nonphysical and physical aggression. Approximately 65% of the children were spanked at least once in the previous month by 1 or both parents. Of couples who reported any family aggression (87%), 54% reported that both CP and IPAV occurred. The most prevalent patterns of co-occurrence involved both parents as aggressors either toward each other (ie, bilateral IPAV) or toward the child. The presence of bilateral IPAV essentially doubled the odds that 1 or both parents would use CP, even after controlling for potential confounders such as parenting stress, depression, and alcohol or other drug use. Of the 5 patterns of co-occurring family aggression assessed, the "single aggressor" model, in which only 1 parent aggressed in the family, received the least amount of empirical support. Despite American Academy of Pediatrics' recommendations against the use of CP, CP use remains common in the United States. CP prevention efforts should carefully consider assumptions made about patterns of co-occurring aggression in families, given that adult victims of IPAV, including even minor, nonphysical aggression between parents, have increased odds of using CP with their children.

Introduction. Emotionally dependent subjects may engage in controlling, restrictive, and aggressive behaviours, which limit their partner's autonomy. The underlying causes of such behaviours are not solely based on levels of aggression, but act as a mean of maintaining the subject's own sense of self-worth, identity, and general functioning. Objective. The aim of the paper is to explore the correlation between affective dependency and reactive/proactive aggression and to evaluate individual differences as predisposing factors for aggressive behaviour and emotional dependency. Methods. The Spouse-Specific Dependency Scale (SSDS) and the Reactive Proactive Questionnaire (RPQ) were administered to a sample of 3375 subjects. Results. In the whole sample, a positive correlation between emotional dependency and proactive aggression was identified. Differences with regard to sex, age group, and geographical distribution were evidenced for the scores of the different scales. Conclusion. A fundamental distinction between reactive and proactive aggression was observed, anchoring proactive aggression more strictly to emotional dependency. Sociocultural and demographical variables, together with the previous structuring of attachment styles, help to determine the scope, frequency, and intensity of the demands made to the partner, as well as to feed the fears of loss, abandonment, or betrayal.

Ventromedial Hypothalamus and the Generation of Aggression

2017-01-01

Aggression is a costly behavior, sometimes with severe consequences including death. Yet aggression is prevalent across animal species ranging from insects to humans, demonstrating its essential role in the survival of individuals and groups. The question of how the brain decides when to generate this costly behavior has intrigued neuroscientists for over a century and has led to the identification of relevant neural substrates. Various lesion and electric stimulation experiments have revealed that the hypothalamus, an ancient structure situated deep in the brain, is essential for expressing aggressive behaviors. More recently, studies using precise circuit manipulation tools have identified a small subnucleus in the medial hypothalamus, the ventrolateral part of the ventromedial hypothalamus (VMHvl), as a key structure for driving both aggression and aggression-seeking behaviors. Here, we provide an updated summary of the evidence that supports a role of the VMHvl in aggressive behaviors. We will consider our recent findings detailing the physiological response properties of populations of VMHvl cells during aggressive behaviors and provide new understanding regarding the role of the VMHvl embedded within the larger whole-brain circuit for social sensation and action.

The living and working arrangements of migrant farmworkers in North Carolina are shaped by grower provided housing, codified by the US Department of Labor's H-2A temporary worker program. Growers typically dictate all facets about residences, living conditions, and even food acquirements. Farmworker camps likely contribute to aggression because of the forced relationships among a small group of people that live, work and recreate together for extended time periods. Participants in the study consisted of 371 farmworkers living in 183 camps. The Revised Conflict Tactics Scale was used to assess aggression among migrant farmworkers. Results indicated that aggressive acts were prevalent among the farmworkers, but the frequency of aggressive acts was low. The most common aggressive act was minor psychological aggression. Results also indicated that alcohol misuse was a common characteristic for both victims and perpetrators and the majority of aggressive acts occurred later in the agricultural season.

Rohlf, Helena; Krahé, Barbara; Busching, Robert

2016-10-01

The current study examined the moderating effect of classroom aggression on the development of individual aggression and on the path from individual aggression to social rejection over time. The study included 1,284 elementary school children and consisted of two data waves 10months apart. At both time points, teachers assessed the children's physical and relational aggression and their social rejection status. Multi-level analyses revealed that the classroom level of relational aggression moderated the link between individual relational aggression at T1 and T2 (b=-0.18, 95% CI [-0.32, -0.05], p<.01) and the link between T1 relational aggression and T2 social rejection (b=-0.12, 95% CI [-0.23, -0.003], p<.01). Being in a classroom where relational aggression was prevalent increased relational aggression among children with a low level of relational aggression at T1. Furthermore, a high individual level of relational aggression predicted greater social rejection in classrooms with a low level of relational aggression. Children were mainly influenced by their same-gender peers. Boys as a group had a greater influence than girls on their peers of either gender in the domain of relational aggression, whereas girls as a group had a greater influence in the domain of physical aggression. The contributions of analyzing cross-level interaction to understanding the developmental patterns of aggression and social rejection in middle childhood are discussed.

Aggressive behavior is one of the most challenging symptoms in psychiatry, and biological markers for aggression lack of large sample validations. Serotonin (5-HT) and other neuroactive compounds deriving from Tryptophan (Trp), including kynurenine (Kyn), have not yet been investigated in large cohorts of aggressive individuals to validate their potential as biomarkers of aggression. In 361 male inmates we measured serum levels of Trp, 5-hydroxytryptophan, 5-HT, Kyn, the ratios 5-HT/Trp∗1000 and Kyn/Trp∗1000, and performed Structured Clinical Interview for DSM-IV Axis-I and -II Disorders (SCID-I and -II), global assessment of functioning (GAF), and scales for aggressive behavior, impulsivity, adult attention-deficit/hyperactivity disorder (ADHD), and intelligent quotient (IQ). Aggressive compared to non-aggressive inmates exhibited lower Trp and Kyn serum levels but higher levels of 5-HT and 5-HT/Trp∗1000, higher levels of impulsivity and ADHD indices, lower IQ and GAF, higher prevalence of mood disorders, drug abuse/dependence, and borderline, conduct and antisocial behaviors. Interestingly, Kyn/Trp∗1000 was positively correlated to the number of severe aggressive acts (r=0.593, P<0.001). After adjusting for confounding factors, logistic regression analysis indicated that 5-HT/Trp∗1000, antisocial behavior, and GAF were predictors of aggressive behavior. The model combining these three predictors had an area under the ROC curve of 0.851 (95% CI 0.806-0.895). This study indicates that while circulating Trp is reduced in aggressive individuals, the combination of biological (5-HT/Trp ratio) and psychopathological (antisocial behavior and GAF) markers discriminates between aggressive and non-aggressive behavior suggesting the potential of a multi-marker approach in psychiatry given the heterogenic nature of mental diseases.

Chen, P.; Coccaro, E. F.; Lee, R.; Jacobson, K. C.

2014-01-01

Background Associations between early life maltreatment, social information processing (SIP) and aggression in childhood and adolescence have been widely documented. Few studies have examined the importance of childhood maltreatment independent of SIP in the etiology of adult aggression. Furthermore, moderating effects of childhood maltreatment on the SIP–aggression links have not been explored. Method Hierarchical, multi-level models were fitted to data from n=2752 twins aged 20–55 years from the PennTwins Cohort. Adult aggression was assessed with the Life History of Aggression questionnaire. Childhood maltreatment was measured using the Childhood Trauma Questionnaire. Two aspects of SIP were examined : hostile attribution biases (HAB) ; negative emotional responses (NER). Results Childhood maltreatment was positively correlated with adult aggression, independently of HAB and NER. In addition, childhood maltreatment moderated the relationships between both aspects of SIP and adult aggression. Specifically, the relationship between NER and aggression was stronger among individuals with higher levels of childhood maltreatment and NER was not associated with aggression for adults who experienced low levels of childhood maltreatment. Moderating effects of childhood maltreatment on the NER–aggression link were supported for total childhood maltreatment, emotional neglect and emotional abuse. In contrast, HAB was more strongly associated with adult aggression at lower levels of emotional abuse and physical neglect. Conclusions The current study provides insight into the mechanisms by which early life experiences influence adult aggression. Our findings suggest that childhood maltreatment may not only lead to increased levels of aggression in adulthood but may also modify the associations between SIP and adult aggression. PMID:22008562

In some communities, local government and non-profit entities have funds to purchase and renovate distressed, foreclosed homes for resale in the affordable housing market. Numerous opportunities to improve whole house energy efficiency are inherent in these comprehensive renovations. BA-PIRC worked together in a multiyear field study making recommendations in individual homes, meanwhile compiling improvement costs, projected energy savings, practical challenges, and labor force factors surrounding common energy-related renovation measures. The field study, Phase 1 of this research, resulted in a set of best practices appropriate to the current labor pool and market conditions in central Florida to achieve projected annualmore » energy savings of 15%-30% and higher. This case study describes Phase 2 of the work where researchers worked with a local government partner to implement and refine the "current best practices". A simulation study was conducted to characterize savings potential under three sets of conditions representing varying replacement needs for energy-related equipment and envelope components. The three scenarios apply readily to the general remodeling industry as for renovation of foreclosed homes for the affordable housing market. The new local government partner, the City of Melbourne, implemented the best practices in a community-scale renovation program that included ten homes in 2012.« less

A COGNITIVE PERSPECTIVE ON AGGRESSIVE MIMICRY

PubMed Central

JACKSON, ROBERT R.; CROSS, FIONA R.

2013-01-01

We use the term ‘aggressive mimic’ for predators that communicate with their prey by making signals to indirectly manipulate prey behaviour. For understanding why the aggressive mimic’s signals work, it is important to appreciate that these signals interface with the prey’s perceptual system, and that the aggressive mimic can be envisaged as playing mind games with its prey. Examples of aggressive mimicry vary from instances in which specifying a model is straight forward to instances where a concise characterisation of the model is difficult. However, the less straightforward examples of aggressive mimicry may be the more interesting examples in the context of animal cognition. In particular, there are spiders that prey on other spiders by entering their prey’s web and making signals. Web invasion brings about especially intimate contact with their prey’s perceptual system because the prey spider’s web is an important component of the prey spider’s sensory apparatus. For the web-invading spider, often there is also a large element of risk when practising aggressive mimicry because the intended prey is also a potential predator. This element of risk, combined with exceptionally intimate interfacing with prey perceptual systems, may have favoured the web-invading aggressive mimic’s strategy becoming strikingly cognitive in character. Yet a high level of flexibility may be widespread among aggressive mimics in general and, on the whole, we propose that research on aggressive mimicry holds exceptional potential for advancing our understanding of animal cognition.

We studied the social and cognitive performance of piglets raised pre-weaning either in a conventional system with a sow in a farrowing crate (FC) or in a multi-suckling (MS) system in which 5 sows and their piglets could interact in a more physically enriched and spacious environment. After weaning at 4 weeks of age, 8 groups of 4 litter-mates per pre-weaning housing treatment were studied under equal and enriched post-weaning housing conditions. From each pen, one pair consisting of a dominant and a submissive pig was selected, based on a feed competition test (FCT) 2 weeks post-weaning. This pair was used in an informed forager test (IFT) which measured aspects of spatial learning and foraging strategies in a competitive context. During individual training, submissive (informed) pigs learned to remember a bait location in a testing arena with 8 buckets (the same bucket was baited in a search visit and a subsequent relocation visit), whereas dominant (non-informed) pigs always found the bait in a random bucket (search visits only). After learning their task, the informed pigs' individual search visit was followed by a pairwise relocation visit in which they were accompanied by the non-informed pig. Effects of pre-weaning housing treatment were not distinctly present regarding the occurrence of aggression in the FCT and the learning performance during individual training in the IFT. During paired visits, informed and non-informed pigs changed their behaviour in response to being tested pairwise instead of individually, but MS and FC pigs showed few distinct behavioural differences.

To explore the usefulness of whole-lesion histogram analysis of apparent diffusion coefficient (ADC) derived from reduced field-of-view (r-FOV) diffusion-weighted imaging (DWI) in differentiating malignant and benign thyroid nodules and stratifying papillary thyroid cancer (PTC) with aggressive histological features. This Institutional Review Board-approved, retrospective study included 93 patients with 101 pathologically proven thyroid nodules. All patients underwent preoperative r-FOV DWI at 3T. The whole-lesion ADC assessments were performed for each patient. Histogram-derived ADC parameters between different subgroups (pathologic type, extrathyroidal extension, lymph node metastasis) were compared. Receiver operating characteristic curve analysis was used to determine optimal histogram parameters in differentiating benign and malignant nodules and predicting aggressiveness of PTC. Mean ADC, median ADC, 5 th percentile ADC, 25 th percentile ADC, 75 th percentile ADC, 95 th percentile ADC (all P < 0.001), and kurtosis (P = 0.001) were significantly lower in malignant thyroid nodules, and mean ADC achieved the highest AUC (0.919) with a cutoff value of 1842.78 × 10 -6 mm 2 /s in differentiating malignant and benign nodules. Compared to the PTCs without extrathyroidal extension, PTCs with extrathyroidal extension showed significantly lower median ADC, 5 th percentile ADC, and 25 th percentile ADC. The 5 th percentile ADC achieved the highest AUC (0.757) with cutoff value of 911.5 × 10 -6 mm 2 /s for differentiating between PTCs with and without extrathyroidal extension. Whole-lesion ADC histogram analysis might help to differentiate malignant nodules from benign ones and show the PTCs with extrathyroidal extension. J. Magn. Reson.

Objective Stimulant treatment improves impulse control among children with attention-deficit/hyperactivity disorder (ADHD). Decreased aggression often accompanies stimulant pharmacotherapy, suggesting that impulsiveness is integral to their aggressive behavior. However, children with high callous-unemotional (CU) traits and proactive aggression may benefit less from ADHD pharmacotherapy because their aggressive behavior seems more purposeful and deliberate. This study’s objective was to determine if pretreatment CU traits and proactive aggression affect treatment outcomes among aggressive children with ADHD receiving stimulant monotherapy. Method We implemented a stimulant optimization protocol with 160 6- to 13-year-olds (mean [SD] age of 9.31 [2.02] years; 78.75% males) with ADHD, oppositional defiant or conduct disorder, and significant aggressive behavior. Family-focused behavioral intervention was provided concurrently. Primary outcome was the Retrospective Modified Overt Aggression Scale. The Antisocial Process Screening Device and the Aggression Scale, also completed by parents, measured CU traits and proactive aggression, respectively. Analyses examined moderating effects of CU traits and proactive aggression on outcomes. Results 82 children (51%) experienced remission of aggressive behavior. Neither CU traits nor proactive aggression predicted remission (CU traits: odds ratio=0.94, 95% CI=0.80–1.11; proactive aggression, odds ratio=1.05, 95% CI=0.86–1.29). Children whose overall aggression remitted showed decreases in CU traits (effect size=−0.379, 95% CI=−0.60 to −0.16) and proactive aggression (effect size=−0.463, 95% CI=−0.69 to −0.23). Conclusions Findings suggest that pretreatment CU traits and proactive aggression do not forecast worse outcomes for aggressive children with ADHD receiving optimized stimulant pharmacotherapy. With such treatment, CU traits and proactive aggression may decline alongside other behavioral improvements

Intra- Versus Intersex Aggression: Testing Theories of Sex Differences Using Aggression Networks.

Wölfer, Ralf; Hewstone, Miles

2015-08-01

Two theories offer competing explanations of sex differences in aggressive behavior: sexual-selection theory and social-role theory. While each theory has specific strengths and limitations depending on the victim's sex, research hardly differentiates between intrasex and intersex aggression. In the present study, 11,307 students (mean age = 14.96 years; 50% girls, 50% boys) from 597 school classes provided social-network data (aggression and friendship networks) as well as physical (body mass index) and psychosocial (gender and masculinity norms) information. Aggression networks were used to disentangle intra- and intersex aggression, whereas their class-aggregated sex differences were analyzed using contextual predictors derived from sexual-selection and social-role theories. As expected, results revealed that sexual-selection theory predicted male-biased sex differences in intrasex aggression, whereas social-role theory predicted male-biased sex differences in intersex aggression. Findings suggest the value of explaining sex differences separately for intra- and intersex aggression with a dual-theory framework covering both evolutionary and normative components. © The Author(s) 2015.

Greenbuilt Retrofit Test House Final Report

DOE Office of Scientific and Technical Information (OSTI.GOV)

2014-06-01

The Greenbuilt house is a 1980's era house in the Sacramento area that was a prominent part of Sacramento Municipal Utility District's (SMUD) Energy Efficient Remodel Demonstration Program. The house underwent an extensive remodel, aimed at improving overall energy efficiency with a goal of reducing the home's energy use by 50%. NREL researchers performed a number of tests on the major systems touched by the retrofit to ensure they were working as planned. Additionally, SMUD rented the house from Greenbuilt Construction for a year to allow NREL to perform a number of tests on the cooling system and the watermore » heating system. The goal of the space conditioning tests was to find the best ways to cut cooling loads and shift the summer peak. The water heating system, comprised of an add-on heat pump water heater and an integrated collector-storage solar water heater, was operated with a number of different draw profiles to see how varying hot water draw volume and schedule affected the performance of the system as a whole. All the experiments were performed with the house empty, with a simulated occupancy schedule running in the house to mimic the load imposed by real occupants.« less

Interactions between zoo-housed great apes and local wildlife.

Ross, S R; Holmes, A N; Lonsdorf, E V

2009-06-01

Although there are published reports of wild chimpanzees, bonobos, and orangutans hunting and consuming vertebrate prey, data pertaining to captive apes remain sparse. In this survey-based study, we evaluate the prevalence and nature of interactions between captive great apes and various indigenous wildlife species that range into their enclosures in North America. Our hypotheses were threefold: (a) facilities housing chimpanzees will report the most frequent and most aggressive interactions with local wildlife; (b) facilities housing orangutans and bonobos will report intermediate frequencies of these interactions with low levels of aggression and killing; and (c) facilities housing gorillas will report the lowest frequency of interactions and no reports of killing local wildlife. Chimpanzees and bonobos demonstrated the most aggressive behavior toward wildlife, which matched our predictions for chimpanzees, but not bonobos. This fits well with expectations for chimpanzees based on their natural history of hunting and consuming prey in wild settings, and also supports new field data on bonobos. Captive gorillas and orangutans were reported to be much less likely to chase, catch and kill wildlife than chimpanzees and bonobos. Gorillas were the least likely to engage in aggressive interactions with local wildlife, matching our predictions based on natural history. However unlike wild gorillas, captive gorillas were reported to kill (and in one case, eat) local wildlife. These results suggest that some behavioral patterns seen in captive groups of apes may be useful for modeling corresponding activities in the wild that may not be as easily observed and quantified. Furthermore, the data highlight the potential for disease transmission in some captive settings, and we outline the associated implications for ape health and safety.

Housing First is a groundbreaking approach to ending chronic homelessness among people with mental illness. This article presents one-year findings from a multisite randomized controlled trial (RCT) comparing Housing First with treatment as usual. The study was a nonblind, parallel-group RCT conducted in five Canadian cities. A sample of 950 high-need participants with severe mental illness, who were either absolutely homeless or precariously housed, was randomly assigned to Housing First (N=469) or treatment as usual (N=481). Housing First participants received a rent supplement, assistance to find housing, and assertive community treatment. Treatment-as-usual participants had access to all other existing programs. At one-year follow-up, 73% of Housing First participants and 31% of treatment-as-usual participants resided in stable housing (p<.001, odds ratio=6.35, covariate adjusted difference=42%, 95% confidence interval [CI]=36%-48%). Improvement in overall quality of life was significantly greater among Housing First participants compared with treatment-as-usual participants (p<.001, d=.31, CI=.16-.46). Housing First participants also showed greater improvements in community functioning compared with treatment-as-usual participants (p=.003, d=.25, CI=.09-.41). Compared with treatment as usual, Housing First produced greater improvements in housing stability, quality of life, and community functioning after one year of enrollment. The study provides support for adopting Housing First as an approach for ending chronic homelessness among persons with severe mental illness, even if they are actively symptomatic or using substances.

We examined, first, the relations between children's exposure to military violence and their aggressive behavior and the role of age and gender in that relation in two Palestinian samples. Second, we tested parenting practices as a moderator of the relation between exposure to military violence and aggressive behavior, and third, whether exposure to military violence of different nature (direct victimization versus witnessing) has specific associations with different forms of aggression (reactive, proactive and aggression-enjoyment). Study I was conducted in a relatively calm military-political atmosphere in Palestine-Gaza, and included 640 children, aged 6-16 years whose parents (N=622) and teachers (N=457) provided reports. Older children (> or =12 years) provided self-reports (N=211). Study II included 225 Palestinian children aged 10-14-year, who participated during a high-violence period of the Al Aqsa Intifada characterized by air raids, killing and destruction. Results showed that witnessing severe military violence was associated with children's aggressive and antisocial behavior (parent-reported) in study I, and with proactive, reactive and aggression-enjoyment (child-reported) in the study II. As hypothesized, good and supporting parenting practices could moderate the link between exposure to military violence and aggressive behavior. Aggr. Copyright 2007 Wiley-Liss, Inc.

Cruel intentions on television and in real life: can viewing indirect aggression increase viewers' subsequent indirect aggression?

PubMed

Coyne, Sarah M; Archer, John; Eslea, Mike

2004-07-01

Numerous studies have shown that viewing violence in the media can influence an individual's subsequent aggression, but none have examined the effect of viewing indirect aggression. This study examines the immediate effect of viewing indirect and direct aggression on subsequent indirect aggression among 199 children ages 11 to 14 years. They were shown an indirect, direct, or no-aggression video and their subsequent indirect aggression was measured by negative evaluation of a confederate and responses to a vignette. Participants viewing indirect or direct aggression gave a more negative evaluation of and less money to a confederate than participants viewing no-aggression. Participants viewing indirect aggression gave less money to the confederate than those viewing direct aggression. Participants viewing indirect aggression gave more indirectly aggressive responses to an ambiguous situation and participants viewing direct aggression gave more directly aggressive responses. This study provides the first evidence that viewing indirect aggression in the media can have an immediate impact on subsequent aggression.

Nursing and aggression in the workplace: a systematic review.

PubMed

Edward, Karen-leigh; Ousey, Karen; Warelow, Philip; Lui, Steve

Personal experiences of aggression or violence in the workplace lead to serious consequences for nurses, their patients, patient care and the organisation as a whole. While there is a plethora of research on this topic, no review is available that identifies types of aggression encountered, individuals perceived to be most at risk and coping strategies for victims. The aim of this systematic review was to examine occupational anxiety related to actual aggression in the workplace for nurses. Databases (MEDLINE, CINAHL and PsycINFO) were searched, resulting in 1543 titles and abstracts. After removal of duplicates and non-relevant titles, 137 papers were read in full. Physical aggression was found to be most frequent in mental health, nursing homes and emergency departments while verbal aggression was more commonly experienced by general nurses. Nurses exposed to verbal or physical abuse often experienced a negative psychological impact post incident.

The aim of the research is a diagnosis of the level of the psychiatric help in social welfare houses. The research was conducted in the form of a questionnaire. The questionnaire was sent at random to 60 houses of social welfare for people with psychic disorders on the whole territory of Poland. 37 responses were received. All the houses in question provide their inhabitants with regular contact with a psychiatrist, 86% inside the social welfare house. 92% of inhabitants have no problems with obtaining referral to psychiatric hospital, however, 70% inhabitants of the social welfare houses have problems with being admitted to hospital. Half of the houses in question use direct compulsion. All the places studied possess therapeutic-caring teams, in 97% of the houses treatment is based on the individual plan. 14% of the houses do not allow the patients to have access to the medical documentation concerning them. In every house integrated pharmacotherapy is used together with various forms of therapy, 76% of the houses involve the family of the patient into the therapeutic process. 78% of those studied note the existence of different factors reducing the quality of the psychiatric care offered. The level of psychiatric care in the social welfare houses is adjusted to the health needs of the patients in the majority of the houses studied. However, the inhabitants have to face the difficulties connected with being admitted to psychiatric hospitals and can have problems with gaining access to medical documentation concerning them. Treatment and rehabilitation of psychic disorders is based on individualized and multi-directional therapeutic interaction. Preparation of the staff providing psychiatric care, especially therapeutic-caring ones, is diversified in individual houses (half of the therapeutic teams do not have a psychiatrist, whose presence seems to be indispensable). The most essential factors reducing the quality of psychiatric care include insufficient financial

The prevalence of verbal aggression against nurses.

PubMed

McLaughlin, Sue; Gorley, Lyn; Moseley, Laurence

There have been many anecdotal and press reports of verbal aggression against nurses. The authors undertook a structured review of the published literature on the topic. They found that no consistent definitions or time periods had been used, a consistent estimate of prevalence was impossible to establish, studies had been retrospective, and the commonest form of measurement had been self-report. There had been no culmination of replicable knowledge. The claim of most studies is that verbal aggression is commonplace in nursing. The best available evidence suggests that verbal aggression is often viewed as 'part of the job'. Consequences can range from emotional effects such as anger and humiliation, through to intent to leave the profession and for some it may have a negative psychological impact. Further research is needed to investigate the multi-faceted nature of verbal aggression. This must be guided by clear definitions and incorporate standardized measures of the effects of verbal aggression so that nurses can compare findings and fully understand all of the complexities and consequences.

Kachadourian, Lorig K; Quigley, Brian M; Leonard, Kenneth E

2014-01-01

Objective: Alcohol aggression expectancies have been found to be associated with increases in aggressive behavior. However, research has not consistently examined evaluations of such behavior. This is unfortunate as both expectancies and evaluations may play a role in whether such behavior will occur. Given this, the current study cross-sectionally examined the associations between alcohol aggression expectancies, evaluations of alcohol-related aggression, indicators of excessive drinking, and alcohol-related verbal and physical aggression. Method: The sample consisted of 280 married and cohabiting couples. These couples reported on excessive drinking indicators, alcohol expectancies and evaluations, and alcohol-related verbal and physical aggression during the past year. Results: Findings showed that verbal aggression was positively associated with indicators of excessive drinking among females and with alcohol aggression expectancies for females who evaluated such aggression positively. For males, aggression expectancies and indicators of excessive drinking were positively associated with verbal aggression. For physical aggression, results showed that indicators of excessive drinking and aggression expectancies were associated with physical aggression for females. For males, aggression expectancies were positively associated and evaluations were negatively associated with physical aggression. Conclusions: These findings add to previous research on alcohol aggression expectancies in close relationships and emphasize the importance of considering evaluations of alcohol-related behavior and how they may play a role in intimate-partner violence and aggression.

Stimulant treatment improves impulse control among children with attention-deficit/hyperactivity disorder (ADHD). Decreased aggression often accompanies stimulant pharmacotherapy, suggesting that impulsiveness is integral to aggressive behavior in these children. However, children with high callous-unemotional (CU) traits and proactive aggression may benefit less from ADHD pharmacotherapy, because their aggressive behavior seems more purposeful and deliberate. This study's objective was to determine whether pretreatment CU traits and proactive aggression affect treatment outcomes among aggressive children with ADHD receiving stimulant monotherapy. We implemented a stimulant optimization protocol with 160 children 6 to 13 years of age (mean [SD] age of 9.31 [2.02] years; 78.75% male) with ADHD, oppositional defiant or conduct disorder, and significant aggressive behavior. Family-focused behavioral intervention was provided concurrently. The primary outcome was the Retrospective Modified Overt Aggression Scale. The Antisocial Process Screening Device and the Aggression Scale, also completed by parents, measured CU traits and proactive aggression, respectively. Analyses examined moderating effects of CU traits and proactive aggression on outcomes. In all, 82 children (51%) experienced remission of aggressive behavior. Neither CU traits nor proactive aggression predicted remission (CU traits: odds ratio [OR] = 0.94, 95% CI = 0.80-1.11; proactive aggression, OR = 1.05, 95% CI = 0.86-1.29). Children whose overall aggression remitted showed decreases in CU traits (effect size = -0.379, 95% CI = -0.60 to -0.16) and proactive aggression (effect size = -0.463, 95% CI = -0.69 to -0.23). Findings suggest that pretreatment CU traits and proactive aggression do not forecast worse outcomes for aggressive children with ADHD receiving optimized stimulant pharmacotherapy. With such treatment, CU traits and proactive aggression may decline alongside other behavioral improvements

Cat aggression redirected to people: 14 cases (1981-1987).

PubMed

Chapman, B L; Voith, V L

1990-03-15

Among 27 cases of cat aggression manifested toward people, 14 cases were diagnosed as redirected or probable redirected aggression, because the cat was already highly aroused by other stimuli before attacking a person. A detailed behavioral history enabled identification of arousing stimuli. The most common arousing stimulus was the presence of another cat. Other arousing stimuli included high-pitched noises, visitors in the house, a dog, an unusual odor, and being outdoors unexpectedly. Medical problems or other behavioral abnormalities were not detected in any of the cats that could explain their aggressive behavior. Management consisted of avoidance or elimination of arousing stimuli wherever possible and extensive client education. On follow-up there was no recurrence of redirected attacks in 4 cats, variable decreases in the severity and frequency of attacks in 5 cats, and no change in 1 cat. Three cats were euthanatized, including one that had shown some improvement. Follow-up information was not available for the 2 remaining cases. Redirected aggression in cats is not well documented and may be misdiagnosed as idiopathic aggression or other behavioral abnormality. Although redirected attacks may be sudden, severe, and frightening, with careful management, a favorable outcome is possible.

This study reports the development of the Reactive–Proactive Aggression Questionnaire (RPQ), and the differential correlates of these two forms of aggression. Antisocial, psychosocial and personality measures were obtained at ages 7 and 16 years in schoolboys, while the RPQ was administered to 334 of the boys at age 16 years. Confirmatory factor analysis indicated a significant fit for a two-factor proactive–reactive model that replicated from one independent subsample to another. Proactive aggression was uniquely characterized at age 7 by initiation of fights, strong-arm tactics, delinquency, poor school motivation, poor peer relationships, single-parent status, psychosocial adversity, substance-abusing parents, and hyperactivity, and at age 16 by a psychopathic personality, blunted affect, delinquency, and serious violent offending. Reactive aggression was uniquely characterized at age 16 by impulsivity, hostility, social anxiety, lack of close friends, unusual perceptual experiences, and ideas of reference. Findings confirm and extend the differential correlates of proactive–reactive aggression, and demonstrate that this brief but reliable and valid self-report instrument can be used to assess proactive and reactive aggression in child and adolescent samples.

Alcohol-related aggression during the college years: theories, risk factors and policy implications.

PubMed

Giancola, Peter R

2002-03-01

The purpose of this article is to present an overview of the research literature on alcohol-related aggression with a focus on college students. Data from both survey studies and experimental laboratory investigations conducted on college students are reviewed. Various methodological approaches to studying the alcohol-aggression relation, and their associated limitations, are then presented and discussed. The literature indicates that alcohol consumption facilitates aggressive behavior and increases the risk of being the victim of a violent act, particularly in heavy drinkers. Results from these studies are then placed into a context by reviewing 12 influential theories of aggression and alcohol-related aggression. On the basis of these theories and empirical data, a preliminary risk profile is presented to help identify which factors are likely to be important in predicting who will and who will not become aggressive after drinking alcohol. Although much research is still needed to elucidate the intricate causes of alcohol-related aggression, current prevention efforts might focus on modifying key risk factors such as poor cognitive functioning and inaccurate expectations about the effects of alcohol. Other prevention efforts directed specifically at college students might focus on helping them to identify risky situations that might facilitate the expression of intoxicated aggression.

120 Years of U.S. Residential Housing Stock and Floor Space.

Residential buildings are a key driver of energy consumption and also impact transportation and land-use. Energy consumption in the residential sector accounts for one-fifth of total U.S. energy consumption and energy-related CO2 emissions, with floor space a major driver of building energy demands. In this work a consistent, vintage-disaggregated, annual long-term series of U.S. housing stock and residential floor space for 1891-2010 is presented. An attempt was made to minimize the effects of the incompleteness and inconsistencies present in the national housing survey data. Over the 1891-2010 period, floor space increased almost tenfold, from approximately 24,700 to 235,150 million square feet, corresponding to a doubling of floor space per capita from approximately 400 to 800 square feet. While population increased five times over the period, a 50% decrease in household size contributed towards a tenfold increase in the number of housing units and floor space, while average floor space per unit remains surprisingly constant, as a result of housing retirement dynamics. In the last 30 years, however, these trends appear to be changing, as household size shows signs of leveling off, or even increasing again, while average floor space per unit has been increasing. GDP and total floor space show a remarkably constant growth trend over the period and total residential sector primary energy consumption and floor space show a similar growth trend over the last 60 years, decoupling only within the last decade.

This short-term longitudinal study examined the associations among relational aggression, physical aggression, and peer status (i.e., acceptance, rejection, and perceived popularity) across three time points, six months apart, in a Taiwanese sample. Participants were 198 fifth grade students (94 girls and 104 boys; Mean age = 10.35 years) from Taipei, Taiwan. Study variables were assessed using peer nomination procedure. Results from the cross-lagged structural equation models demonstrated that there were longitudinal associations between relational aggression and each of the peer status constructs while only one longitudinal association was found for physical aggression such that physical aggression positively predicted subsequent peer rejection. The longitudinal associations did not vary with gender. Results also showed high stabilities of relational aggression, physical aggression, and the three peer status constructs over 1 year as well as high concurrent association between relational and physical aggression. In addition, relational aggression and physical aggression were concurrently related to less acceptance, more rejection, and less perceived popularity, especially at the outset of the study. Findings of this study demonstrated both similarities and differences in relation to previous literature in primarily Western cultures. This study also highlights the bidirectional and complex nature of the association between aggression and peer status, which appears to depend on the form of aggression and on the particular indicator of peer status under study.

Since the Great East Japan Earthquake in 2011, many of the affected have been forced to live in temporary housing or at a relative's house. Special attention needs to be paid to the negative health impacts resulting from such changes in living conditions. This study examined the association between future housing prospects and the risk of psychological distress 1 year after the earthquake. In 2012, a questionnaire was completed by a cross-sectional study of people aged 20 years or older living in Shichigahama Town, Miyagi, northeastern Japan, an area that had been severely inundated by the tsunami. Future housing prospects post-earthquake were classified into four categories: already settled in permanent housing, moving to new housing, under consideration, or unable to make any plans. Psychological distress was evaluated using the Kessler 6 scale, defined as ≥5 points out of 24. We performed multiple logistic regression analyses adjusted for potential confounding factors. Of the 3614 individuals studied, subjects whose future housing was under consideration (odds ratio [OR] = 2.1, 95% confidence interval [CI] = 1.6-2.7, P < 0.01) and those who were unable to make any future housing plans (OR = 1.9, 95%CI = 1.4-2.5, P < 0.01) exhibited a significantly higher risk of psychological distress compared with subjects who had already settled in permanent housing. In this study, subjects whose future housing prospects were under consideration and those who were unable to make any future housing plans were at a higher risk of psychological distress 1 year after the earthquake disaster. © 2015 The Authors.

A Testosterone-Related Structural Brain Phenotype Predicts Aggressive Behavior From Childhood to Adulthood

Structural covariance, the examination of anatomic correlations between brain regions, has emerged recently as a valid and useful measure of developmental brain changes. Yet the exact biological processes leading to changes in covariance, and the relation between such covariance and behavior, remain largely unexplored. The steroid hormone testosterone represents a compelling mechanism through which this structural covariance may be developmentally regulated in humans. Although steroid hormone receptors can be found throughout the central nervous system, the amygdala represents a key target for testosterone-specific effects, given its high density of androgen receptors. In addition, testosterone has been found to impact cortical thickness (CTh) across the whole brain, suggesting that it may also regulate the structural relationship, or covariance, between the amygdala and CTh. Here we examined testosterone-related covariance between amygdala volumes and whole-brain CTh, as well as its relationship to aggression levels, in a longitudinal sample of children, adolescents, and young adults 6 to 22 years old. We found: (1) testosterone-specific modulation of the covariance between the amygdala and medial prefrontal cortex (mPFC); (2) a significant relationship between amygdala-mPFC covariance and levels of aggression; and (3) mediation effects of amygdala-mPFC covariance on the relationship between testosterone and aggression. These effects were independent of sex, age, pubertal stage, estradiol levels and anxious-depressed symptoms. These findings are consistent with prior evidence that testosterone targets the neural circuits regulating affect and impulse regulation, and show, for the first time in humans, how androgen-dependent organizational effects may regulate a very specific, aggression-related structural brain phenotype from childhood to young adulthood.

Oleamide (cis-9,10-octadecenoamide) is an endogenous sleep-inducing lipid and prototypic member of a new class of biological signaling molecules identified in recent years. In the present study, the anxiolytic-like effect of oleamide was studied in several experimental models of anxiety in group-housed and socially isolated mice. As the results show, socially isolated mice exhibited an anxiogenic-like profile in the elevated plus-maze test, the light/dark test, and the hole-board test, which could be significantly reversed by oleamide (10 or 20 mg/kg, i.p.). Moreover, oleamide significantly reduced the anxiety levels in grouped-housed mice. In the isolation-induced aggressive test, oleamide markedly reduced the attacking duration and increased the attacking latency. It is concluded that oleamide has an anxiolytic-like effect in socially isolated or group-housed mice, which suggests that fatty acid amides might be involved in the regulation of anxiety-related behavior in mice.

Background: Youth indulgence themselves in various aggressive behaviors leading to significant psychosocial dysfunctions. The present study assesses the prevalence of aggression among youth and to assess the risk factors of aggression among youth. Materials and Methods: Anger Data sheet, Resilience Scale and Buss-Perry Aggression Scale, were administered on 5476 participants using survey design. Data was collected from different communities (college, residential, apartments and workplace) of Bangalore, Jammu, Indore, Kerala, Rajasthan, Sikkim and Delhi. 47% were female and 53% were male. The mean age of the sample was 20.2 years. Comparative analysis was carried out by Pearson correlation coefficient and Chi-square was also carried out. Results: About 17.7% of the youth has high mean aggression score on Buss-Perry Aggression Scale. Males have high mean score on aggression than females. Males experienced more verbal aggression, physical aggression and anger than females. Younger age group (16-19 years) experienced more aggression than older age group (20-26 years). The risk factors of the youth aggressions were identified as physical abuse in childhood, substance abuse such as alcohol and tobacco, negative peer influence, family violence, academic disturbance, psychological problems attention deficit-hyperactivity disorder, suspicious, loneliness, mood disturbance, negative childhood experience and TV and media. Conclusion: The study document, the presence of correlates of risk factors of aggression among youth and implies usages of management strategies to help them to handle aggression. PMID:24701010

The Overlap of Youth Violence Among Aggressive Adolescents with Past-Year Alcohol Use—A Latent Class Analysis: Aggression and Victimization in Peer and Dating Violence in an Inner City Emergency Department Sample

Objective: The purpose of this study was to identify overlap and violence types between peer and dating aggression and victimization using latent class analysis (LCA) among a sample of aggressive adolescents with a history of alcohol use and to identify risk and protective factors associated with each violence class. Method: From September 2006 to September 2009, a systematic sample of patients (14–18 years old) seeking care in an urban emergency department were approached. Adolescents reporting any past-year alcohol use and aggression completed a survey using validated measures including types of violence (severe and moderate aggression, severe and moderate victimization with both peers and dating partners). Using LCA, violence classes were identified; correlates of membership in each LCA class were determined. Results: Among this sample (n = 694), LCA identified three classes described as (a) peer aggression (PA) (52.2%), (b) peer aggression + peer victimization (PAPV) (18.6%), and (c) multiple domains of violence (MDV) (29.3%). Compared with those in the PA class, those in the PAPV class were more likely to be male, report injury in a fight, and have delinquent peers. Compared with the PA class, those in the MDV class were more likely to be female, African American, report injury in a fight, carry a weapon, experience negative consequences from alcohol use, and have delinquent peers and more family conflict. Compared with the PAPV class, those in the MDV class were likely to be female, African American, receive public assistance, carry a weapon, experience negative consequences from alcohol use, and use marijuana. Conclusions: There is extensive overlap of victimization and aggression in both peer and dating relationships. Also, those with high rates of violence across relationships have increased alcohol misuse and marijuana use. Thus, violence-prevention efforts should consider addressing concomitant substance use.

This study examined specific forms of emotional reactivity to conflict and temperamental emotionality as explanatory mechanisms in pathways among interparental aggression and child psychological problems. Participants of the multi-method, longitudinal study included 201 two-year-old children and their mothers who had experienced elevated violence in the home. Consistent with emotional security theory, autoregressive structural equation model analyses indicated that children’s fearful reactivity to conflict was the only consistent mediator in the associations among interparental aggression and their internalizing and externalizing symptoms one year later. Pathways remained significant across maternal and observer ratings of children’s symptoms and with the inclusion of other predictors and mediators, including children’s sad and angry forms of reactivity to conflict, temperamental emotionality, gender, and socioeconomic status.

Who is violent?: factors associated with aggressive behaviors in Latin America and Spain.

PubMed

Orpinas, P

1999-01-01

The main purpose of this paper was to evaluate the strength of the association between: 1) aggressive behaviors and 2) attitudes and self-efficacy for alternatives to violence, in different cities of the Region of the Americas and Spain. Results were based on a cross-sectional house-hold survey of a sample of the population aged 18 to 70 years. The survey was conducted in eight metropolitan areas of Latin America and Spain: Rio de Janeiro, Brazil; Salvador, Bahia, Brazil; Santiago, Chile; Cali, Colombia; San José, Costa Rica; San Salvador, El Salvador; Caracas, Venezuela; and Madrid, Spain. Each sample of approximately 1,200 respondents per city was stratified by clusters and was proportional in terms of socioeconomic position and population density. In all cities and for all targets of aggression studied, people who reported using aggression were less likely to feel confident that they could solve conflicts without violence, and they were more likely to hold attitudes supporting violence. Young persons were also more likely to commit aggression against all the targets. In addition, aggression toward nonfamily members was found most frequently among young men who reported binge drinking, who either carried a firearm or would have liked to carry one, or who perceived the police as inefficient. Additional studies need to be done in each country to describe more specific attitudes associated with aggression within each subculture. Future prevention programs should focus on modifying attitudes that support violence, increasing self-efficacy in solving problems without using violence, supporting the development of a police system that people can trust, regulating firearms and access to alcohol, and raising people's education levels.

2004-12-01

In order to evaluate the special injury pattern of aggressive inline skating, a field study was conducted in a local, non-commercial skate park equipped with all the typical features like ramps, halfpipes, gully areas. 66 unselected aggressive inline skaters were randomly enrolled and interviewed concerning their skating habits and their skating injury history. Average age was 15 (10 to 41) years, skating was performed since 2.1 (0.1 to 6) years, as aggressive skating since 1.3 (0.1 to 4) years. Medical treatment in a doctor's practice or in a hospital had been necessary in 66 cases, averaging 1.4 times per skater and year, averaging one injury per 586 hours of aggressive skating. The injury pattern reflected the regions typically injured in fitness skating, too, with a higher percentage of injuries concerning knee, tibia and ankle region. The use of protective devices varied from 41 % (wrist guards) to 94 % (knee pads), with an average of 69 %. Only 32 % of skaters wore all protective devices. As the personal thrill is an important motivation for aggressive skating, safer skating campaigns are quite unlikely to decrease the risk of injury in aggressive skaters.

Predictors of aggression on the psychiatric inpatient service: self-esteem, narcissism, and theory of mind deficits.

2007-05-01

Aggressive behavior committed by inpatients has significant negative effects on patients, clinical staff, the therapeutic milieu, and inpatient community as whole. Past research examining nonpsychiatric patient groups has suggested that elevated self-esteem and narcissism levels as well as self-serving theory of mind (ToM) biases may be robust predictors of aggressive behavior. In the present study, we examined whether these constructs were useful in predicting aggressive acts committed by psychiatric inpatients. Severity of psychiatric symptoms, demographic variables and patients' anger, and hostility severity were also examined. We found patients who committed acts of aggression were differentiated from their nonaggressive counterparts by exhibiting significantly higher levels of self-esteem and narcissistic superiority. In addition, aggressors demonstrated self-serving ToM biases, attributing more positive attributes to themselves, relative to their perceptions of how others viewed them. Aggressors also showed increased psychosis, fewer depressive symptoms, and had significantly fewer years of formal education than their nonaggressive peers. These results support and extend the view that in addition to clinical variables, specific personality traits and self-serving attributions are linked to aggressive behavior in acutely ill psychiatric patients.

A longitudinal test of video game violence influences on dating and aggression: a 3-year longitudinal study of adolescents.

2012-02-01

In 2011 the field of video game violence experienced serious reversals with repudiations of the current research by the US Supreme Court and the Australian Government as non-compelling and fundamentally flawed. Scholars too have been calling for higher quality research on this issue. The current study seeks to answer this call by providing longitudinal data on youth aggression and dating violence as potential consequences of violent video game exposure using well-validated clinical outcome measures and controlling for other relevant predictors of youth aggression. A sample of 165, mainly Hispanic youth, were tested at 3 intervals, an initial interview, and 1-year and 3-year intervals. Results indicated that exposure to video game violence was not related to any of the negative outcomes. Depression, antisocial personality traits, exposure to family violence and peer influences were the best predictors of aggression-related outcomes. The current study supports a growing body of evidence pointing away from video game violence use as a predictor of youth aggression. Public policy efforts, including funding, would best be served by redirecting them toward other prevention programs for youth violence. Copyright © 2011 Elsevier Ltd. All rights reserved.

2011-01-01

The effects of chronic intra-peritoneal administration of 10 mg/kg (t.i.w., for 5 weeks) of sildenafil on competitive aggression, sexual behaviour and body weight gain was tested in CD1 subordinate male mice in two experimental contexts: 1) "low levels of aggression", i.e. housing in dyads of siblings 2) "high levels of aggression", i.e. exposure to a model of chronic psychosocial stress with an unfamiliar mice. Subordinate mice in both experimental contexts were injected with sildenafil or saline. After 2 weeks of sildenafil administration, a subgroup of subordinates exposed to "high levels of aggression" began to counterattack their dominant counterparts at higher rates than saline-injected subordinates. This effect was essentially similar but faster in subordinates subjected to "low levels of aggression". As far as sexual behaviour is concerned, in both experimental contexts, sildenafil-injected subordinated mice showed significant lower latencies to mount a proceptive female when compared to saline-injected subjects. Furthermore, in the "high levels of aggression" context, Sildenafil reduced stress-induced body weight gain. Sildenafil showed no effects in individually housed males serving as controls. In conclusion, chronic Sildenafil treatment counteracts the inhibitory effects of social subordination on male competitive aggression, sexual behaviour and body weight gain. Overall our data suggests that sildenafil could be acting in the central nervous system to modulate sexual and agonistic motivation. Copyright © 2010 Elsevier B.V. All rights reserved.

Effects of childhood aggression on parenting during adolescence: the role of parental psychological need satisfaction.

2013-01-01

The current study examined the explanatory role of satisfaction of parental psychological needs in effects of childhood aggression on various adolescent-perceived parenting behaviors in middle adolescence. Research questions were examined in a large multi-informant, prospective community study of ethnic majority Belgian families (N = 609, 49.7% girls). Aggression was rated by parents when children were in middle childhood (M age = 7.5 years) using the Child Behavior Checklist. Parents reported on satisfaction of their needs for autonomy, competence, and relatedness when children were in preadolescence (M age = 10.5 years) and early adolescence (M age = 13.5 years) using the Parenting Stress Index. Parenting behaviors were rated by adolescents in early adolescence (M age = 13.5 years) and in middle adolescence (M age = 15.5 years), using the Parenting Scale (overreactive discipline), the Psychological Control Scale, Youth Self-Report (psychological control), and the Parenting Practices Questionnaire (warmth). Mediation of associations from aggression to parenting by parents' psychological needs was examined using multiple mediation structural equation modeling analyses. Childhood aggression was related to decreased satisfaction of parents' needs for competence, relatedness, and autonomy in early adolescence. Satisfaction of parents' needs for relatedness and, to a lesser extent, competence affected later parenting, and satisfaction of all three needs affected changes in parenting. Relations were specific for the different parenting constructs but similar across parental gender. Targeting parents' psychological needs may aid effectiveness of interventions that are aimed at decreasing (psychologically, overreactive) controlling parenting and at increasing supportive parenting.

To Group or Not to Group? Good Practice for Housing Male Laboratory Mice

Kappel, Sarah; Hawkins, Penny; Mendl, Michael T.

2017-01-01

Simple Summary Wild mice live in territories inhabited by one adult male, several females, and their offspring. This cannot be replicated in the laboratory, so male mice are usually housed in single-sex groups or individually. However, there can be serious animal welfare problems associated with both these approaches, such as lack of social contact when housed individually or aggression between males when kept in groups. Group housing is widely recommended to give male laboratory mice the opportunity to behave as ‘social animals’, but social stress can be detrimental to the welfare of these animals, even without injurious fighting. All of this can also affect the quality of the science, giving rise to ethical concerns. This review discusses whether it is in the best welfare interests of male mice to be housed in groups, or alone. We conclude that it is not possible to give general recommendations for good practice for housing male laboratory mice, as responses to single- and group-housing can be highly context-dependent. The welfare implications of housing protocols should be researched and considered in each case. Abstract It is widely recommended to group-house male laboratory mice because they are ‘social animals’, but male mice do not naturally share territories and aggression can be a serious welfare problem. Even without aggression, not all animals within a group will be in a state of positive welfare. Rather, many male mice may be negatively affected by the stress of repeated social defeat and subordination, raising concerns about welfare and also research validity. However, individual housing may not be an appropriate solution, given the welfare implications associated with no social contact. An essential question is whether it is in the best welfare interests of male mice to be group- or singly housed. This review explores the likely impacts—positive and negative—of both housing conditions, presents results of a survey of current practice and

Aggression and Violence among Iranian Adolescents and Youth: A 10-year Systematic Review

Sadeghi, Saeid; Farajzadegan, Ziba; Kelishadi, Roya; Heidari, Kamal

2014-01-01

Background: Although the overwhelming majority of Iranian adolescents are well-adjusted, a substantial group exhibits high levels of maladjustment and deficient functioning. Escalation of criminal violence among the youth population has become a major public policy issue and a serious public health problem. In reviewing a 10-year literature, this article aimed to describe and propose primary assumptions regarding the correlates of aggressive and violent behaviors in Iranian adolescents and youth. Methods: Bibliographic databases such as PubMed and Google Scholar along with Iranian databases including PubMed, IranMedex, Magiran, Irandoc, Psychoinfo, and Emrofor Scientific Information Database, and Magiran constituted the databases which we searched for the relevant literature. Overall 98 articles met the inclusion criteria, allowing us to initiate the discussion. Results: Reportedly, prevalence of violence and aggression among the Iranian adolescents and youth ranged from 30% to 65.5% while males being 2½ times more affected than females. The role of gender, family environment, family size, socioeconomic status, and victimization in perpetuating the circumstances was apparent. Conclusions: Relatively high prevalence of violence and aggression among Iranian youth and adolescents is a warning sign and a great challenge to the social system. Reviewed studies suffer from certain methodological and conceptual limitations. Undertaking community-based studies to estimate the actual extent of the problem is warranted. PMID:26157572

120 years of U.S. residential housing stock and floor space

Moura, Maria Cecilia P.; Smith, Steven J.; Belzer, David B.

Residential buildings are a key driver of energy consumption and also impact transportation and land-use. Energy consumption in the residential sector accounts for one-fifth of total U.S. energy consumption and energy-related CO₂ emissions, with floor space a major driver of building energy demands. In this work a consistent, vintage-disaggregated, annual long-term series of U.S. housing stock and residential floor space for 1891–2010 is presented. An attempt was made to minimize the effects of the incompleteness and inconsistencies present in the national housing survey data. Over the 1891–2010 period, floor space increased almost tenfold, from approximately 24,700 to 235,150 million squaremore » feet, corresponding to a doubling of floor space per capita from approximately 400 to 800 square feet. While population increased five times over the period, a 50% decrease in household size contributed towards a tenfold increase in the number of housing units and floor space, while average floor space per unit remains surprisingly constant, as a result of housing retirement dynamics. In the last 30 years, however, these trends appear to be changing, as household size shows signs of leveling off, or even increasing again, while average floor space per unit has been increasing. GDP and total floor space show a remarkably constant growth trend over the period and total residential sector primary energy consumption and floor space show a similar growth trend over the last 60 years, decoupling only within the last decade.« less

Effect of Enrichment Devices on Aggression in Manipulated Nude Mice.

2015-11-01

Agonistic behavior in group-housed male mice is a recurring problem in many animal research facilities. Common management procedures, such as the removal of aggressors, are moderately successful but often fail, owing to recurrence of aggressive behavior among cagemates. Studies have incorporated enrichment devices to attenuate aggression, but such devices have had mixed results. However, these studies did not include research manipulations when assessing the benefits of various enrichment devices. We obtained 100 male athymic nude mice and studied the efficacy of various enrichment devices, including cotton squares, paper rolls, shredded paper, nylon bones, and a mouse house and wheel combination in the reduction of fighting during an ongoing study that involved randomization followed by prostate and intratibial injections. Groups were evaluated according to a numerical grading system for wound assessment. Examination of the data revealed that the enrichment devices had no effect on the presence of wounds, thus none of the devices tested affected fighting in nude mice. However, when mice began experimental use, fight wounds increased significantly at cage change and after randomization, reflecting a disruption of existing social hierarchies. Therefore, in the context of an actual research study that involves common manipulations, the specific enrichment device had less effect on aggression in male nude mice than did the destruction and reconstruction of social structures within each group.

There is a largely unmet need for evidence-based interventions that reduce future aggression and incarceration in clinically aggressive juvenile offenders serving probation. We addressed this gap using a group randomized controlled trial. Offenders both with and without clinical aggression were included, enabling comparison of intervention effects. Juveniles 13 to 17 years old (N = 310, mean = 16 years, 90% African-American, 66% male) on probation were assigned to a 2-week intervention targeting psychosocial factors implicated in risky behavior (e.g., learning strategies to manage "hot" emotions that prompt risk taking) or to an equally intensive health promotion control. Participants completed aggression measures at baseline, 6-, and 12-month follow-up and reported on incarceration at 12 months. Spline regression tested symptom change. Among clinically aggressive offenders (n = 71), the intervention arm showed significantly greater reductions in aggression over the first 6 months compared with controls. Juveniles from the intervention no longer met clinical criteria, on average, but clinically significant symptoms persisted in the control group. By 12 months, participants from the intervention appeared to maintain treatment gains, but their symptom levels no longer differed significantly from those in the control. However, the intervention group was nearly 4 times less likely than controls to report incarceration. Intervention effects were significantly stronger for offenders with clinical than with nonclinical (n = 239) baseline aggression. A 2-week intervention expedited improvements in aggression and reduced incarceration in clinically aggressive juvenile offenders. The findings underscore the importance of directing intervention resources to the most aggressive youth.

2012-01-01

Background The aim of this study was to identify what is most important to the quality of life (QoL) of those who experience homelessness by directly soliciting the views of homeless and hard-to-house Canadians themselves. These individuals live within a unique social context that differs considerably from that of the general population. To understand the life areas that are most important to them, it is critical to have direct input from target populations of homeless and hard-to-house persons. Methods Focus groups were conducted with 140 individuals aged 15 to 73 years who were homeless or hard-to-house to explore the circumstances in which they were living and to capture what they find to be important and relevant domains of QoL. Participants were recruited in Toronto, Ottawa, Montreal, and Vancouver. Content analysis was used to analyze the data. Results Six major content themes emerged: Health/health care; Living conditions; Financial situation; Employment situation; Relationships; and Recreational and leisure activities. These themes were linked to broader concepts that included having choices, stability, respect, and the same rights as other members of society. Conclusions These findings not only aid our understanding of QoL in this group, but may be used to develop measures that capture QoL in this population and help programs and policies become more effective in improving the life situation for persons who are homeless and hard-to-house.

A comparison of the effectiveness of whole house (point-of-entry) and point-of-use arsenic water treatment systems in reducing arsenic exposure from well water was conducted. The non-randomized observational study recruited 49 subjects having elevated arsenic in their residential home well water in New Jersey. The subjects obtained either point-of-entry or point-of-use arsenic water treatment. Prior ingestion exposure to arsenic in well water was calculated by measuring arsenic concentrations in the well water and obtaining water-use histories for each subject, including years of residence with the current well and amount of water consumed from the well per day. A series of urine samples were collected from the subjects, some starting before water treatment was installed and continuing for at least nine months after treatment had begun. Urine samples were analyzed and speciated for inorganic-related arsenic concentrations. A two-phase clearance of inorganic-related arsenic from urine and the likelihood of a significant body burden from chronic exposure to arsenic in drinking water were identified. After nine months of water treatment the adjusted mean of the urinary inorganic-related arsenic concentrations were significantly lower (p < 0.0005) in the point-of-entry treatment group (2.5 μg/g creatinine) than in the point-of-use treatment group (7.2 μg/g creatinine). The results suggest that whole house arsenic water treatment systems provide a more effective reduction of arsenic exposure from well water than that obtained by point-of-use treatment.

In 2009, Transformations, Inc. partnered with Building America team Building Science Corporation (BSC) to build new net zero energy houses in three developments in Massachusetts. The company has been developing strategies for cost-effective super-insulated homes in the New England market since 2006. After years of using various construction techniques, it has developed a specific set of assemblies and specifications that achieve a 44.9% reduction in energy use compared with a home built to the 2009 International Residential Code, qualifying the houses for the DOE’s Challenge Home. The super-insulated houses provide data for several research topics in a cold climate. BSCmore » studied the moisture risks in double stud walls insulated with open cell spray foam and cellulose. The mini-split air source heat pump (ASHP) research focused on the range of temperatures experienced in bedrooms as well as the homeowners’ perceptions of equipment performance. BSC also examined the developer’s financing options for the photovoltaic (PV) systems, which take advantage of Solar Renewable Energy Certificates, local incentives, and state and federal tax credits.« less

Aggressive and nonaggressive children's moral judgments and moral emotion attributions in situations involving retaliation and unprovoked aggression.

PubMed

Gasser, Luciano; Malti, Tina; Gutzwiller-Helfenfinger, Eveline

2012-01-01

The authors investigated 7- and 9-year-old children's moral understanding of retaliation as compared to unprovoked aggression with regard to their aggressive behavior status. Based on peer ratings, 48 children were selected as overtly aggressive and 91 as nonaggressive. Their moral understanding of retaliation and unprovoked aggression was assessed by an interview including questions about their moral judgments and emotion attributions. Aggressive children judged retaliations as less serious than did nonaggressive children. They also referred less often to the harmful consequences of retaliation and were more likely to excuse the retaliation because of the provocation. In unprovoked aggressive situations younger aggressive children, compared with the younger nonaggressive children, attributed more happiness to transgressors, more anger to victims, and less sadness to transgressors and victims. The results are discussed in terms of previous research on aggressive children's moral understanding of retaliation and unprovoked aggression.

2008-11-01

A novel method for determining whole house particle removal and clean air delivery rates attributable to central and portable ventilation/air cleaning systems is described. The method is used to characterize total and air-cleaner-specific particle removal rates during operation of four in-duct air cleaners and two portable air-cleaning devices in a fully instrumented test home. Operation of in-duct and portable air cleaners typically increased particle removal rates over the baseline rates determined in the absence of operating a central fan or an indoor air cleaner. Removal rates of 0.3- to 0.5-microm particles ranged from 1.5 hr(-1) during operation of an in-duct, 5-in. pleated media filter to 7.2 hr(-1) for an in-duct electrostatic air cleaner in comparison to a baseline rate of 0 hr(-1) when the air handler was operating without a filter. Removal rates for total particulate matter less than 2.5 microm in aerodynamic diameter (PM2.5) mass concentrations were 0.5 hr(-1) under baseline conditions, 0.5 hr(-1) during operation of three portable ionic air cleaners, 1 hr(-1) for an in-duct 1-in. media filter, 2.4 hr(-1) for a single high-efficiency particle arrestance (HEPA) portable air cleaner, 4.6 hr(-1) for an in-duct 5-in. media filter, 4.7 hr(-1) during operation of five portable HEPA filters, 6.1 hr(-1) for a conventional in-duct electronic air cleaner, and 7.5 hr(-1) for a high efficiency in-duct electrostatic air cleaner. Corresponding whole house clean air delivery rates for PM2.5 attributable to the air cleaner independent of losses within the central ventilation system ranged from 2 m3/min for the conventional media filter to 32 m3/min for the high efficiency in-duct electrostatic device. Except for the portable ionic air cleaner, the devices considered here increased particle removal indoors over baseline deposition rates.

Adults exhibiting severe impulsive and aggressive behaviors have multiple indices of low serotonin (5-HT) neurotransmission. It remains unclear though whether low 5-HT mediates the behavior or instead reflects a pre-existing vulnerability trait. In the present study, positron emission tomography with the tracer alpha-[(11)C]methyl-L-tryptophan ((11)C-AMT) was used to compare 5-HT synthesis capacity in two groups of adult males from a 21-year longitudinal study (mean age +/- SD: 27.1+/-0.7): individuals with a history of childhood-limited high physical aggression (C-LHPA; N = 8) and individuals with normal (low) patterns of physical aggression (LPA; N = 18). The C-LHPA males had significantly lower trapping of (11)C-AMT bilaterally in the orbitofrontal cortex and self-reported more impulsiveness. Despite this, in adulthood there were no group differences in plasma tryptophan levels, genotyping, aggression, emotional intelligence, working memory, computerized measures of impulsivity, psychosocial functioning/adjustment, and personal and family history of mood and substance abuse disorders. These results force a re-examination of the low 5-HT hypothesis as central in the biology of violence. They suggest that low 5-HT does not mediate current behavior and should be considered a vulnerability factor for impulsive-aggressive behavior that may or may not be expressed depending on other biological factors, experience, and environmental support during development.

2014-11-18

Mental health professionals are often asked to give advice about managing children's aggression. Good quality evidence on contributory environmental factors such as seeing aggression on television and in video games is relatively lacking, although societal and professional concerns are high. This study investigated possible associations between seeing aggression in such media and the aggressive behaviour of children attending specialist outpatient child and adolescent mental health services (CAMHS). In this mixed methods study, forty-seven British children aged 7-11 years with behavioural/emotional difficulties attending CAMHS and their carers participated in a survey; twenty purposively-selected children and a parent/carer of theirs participated in a qualitative study, involving semi-structured interviews, analysed using the Framework Analysis Approach; findings were integrated. Children attending CAMHS exhibit clinically significant aggression, of varying types and frequency. They see aggression in multiple real and virtual settings. Verbal aggression was often seen, frequently exhibited and strongly associated with poor peer relationships and low prosocial behaviour. Children did not think seeing aggression influences their own behaviour but believed it influences others. Carers regarded aggression as resulting from a combination of inner and environmental factors and seeing aggression in real-life as having more impact than television/video games. There is yet no definitive evidence for or against a direct relationship between aggression seen in the media and aggression in children with behavioural/emotional difficulties. Future research should take an ecological perspective, investigating individual, developmental and environmental factors. Carers, professional organisations and policy makers should address aggression seen in all relevant area of children's lives, primarily real-life and secondly virtual environments.

Young men’s intimate partner violence and relationship functioning: Long-term outcomes associated with suicide attempt and aggression in adolescence

Kerr, David C. R.; Capaldi, Deborah M.

2010-01-01

Background Longitudinal research supports that suicidal thoughts and behaviors in adolescence predict maladjustment in young adulthood. Prior research supports links between suicide attempt and aggression, perhaps because of a propensity for impulsive behavior in states of high negative affect that underlies both problems. Such vulnerability may increase risk for intimate partner violence and generally poor young adulthood relational adjustment. Method 153 men participated in annual assessments from ages 10 to 32 years and with a romantic partner at three assessments from ages 18 to 25 years. Multimethod/multi-informant constructs were formed for parent/family risk factors, adolescent psychopathology (e.g., suicide attempt history; mother-, father-, teacher-, and self-reported physical aggression), and young adulthood relational distress (jealousy and low relationship satisfaction) and maladaptive relationship behavior (observed, self-, and partner-reported physical and psychological aggression toward a partner, partner-reported injury, official domestic violence arrest records, and relationship instability). Results Across informants, adolescent aggression was correlated with suicide attempt history. With few exceptions, aggression and a suicide attempt in adolescence each predicted negative romantic relationship outcomes after controlling for measured confounds. Adolescent aggression predicted young adulthood aggression toward a partner, in part, via relationship dissatisfaction. Conclusions Boys’ aggression and suicide attempt history in adolescence each predict poor relationship outcomes, including partner violence, in young adulthood. Findings are consistent with the theory of a trait-like vulnerability, such as impulsive aggression, that undermines adaptation across multiple domains in adolescence and young adulthood. Prevention and intervention approaches can target common causes of diverse public health problems. PMID:20540815

2012-01-01

Individual and organizational characteristics associated with aggressive behavior among nursing home residents were examined among a sample of 5,494 residents from 23 facilities using the Minimum Data Set 2.0 and the Organizational Social Context scale. On admission, some individual level variables (age, sex, depression, activities of daily life [ADL] impairments, and cognitive impairments) and no organizational level variables were associated with aggressive behaviors. Over time, aggressive behaviors were linked with some individual characteristics (age, sex, and ADL impairments) and several organizational level variables (stressful climates, less rigid cultures, more resistant cultures, geographic location, facility size and staffing patterns). Findings suggest multi-faceted change strategies are needed.

Regular airtightness tests were performed on 24 new houses, over periods of up to three years, to evaluate their air barrier systems and to search for evidence, air barrier degradation. Ten of the houses were constructed with polyethylene air barriers while the remaining 14 used an early version of the Airtight Drywall Approach (ADA). The 24 project houses were architecturally similar and of approximately equal size and general layout; stucco was the predominate exterior wall finish. All were exposed to similar terrain shielding. The study found that the airtightness of the polyethylene air barrier houses remained stable over their respectivemore » monitoring periods. Although two of the ten houses demonstrated possible, albeit slight, evidence of airtightness degradation, the magnitude of these changes was small and judged not to be of practical significance. With respect to the critical issue of air barrier degradation, no evidence could be found to indicate polyethylene is unsuited for use as an air barrier material in residential construction. For example, all but one of the polyethylene houses met the airtightness requirements of the Canadian R-2000 Standard for energy efficient housing at the end of their monitoring periods. The study found that the airtightness of the 14 ADA houses also remained stable over their monitoring periods. Although six of the 14 houses displayed possible, but slight, evidence of airtightness degradation, the magnitude of the changes was small and not of practical significance. It was concluded that no evidence could be found to indicate that the ADA system is unsuited for use in residential construction. All 14 ADA houses met the airtightness requirements of the R-2000 Program at the end of their respective monitoring periods.« less

Intervention for aggressive victims of school bullying in Hong Kong: a longitudinal mixed-methods study.

2012-08-01

The distinction between aggressive and passive victims of school bullying is well documented. Aggressive victims exhibit restlessness and hot-temperedness, are easily provoked, and take revenge when irritated, whereas passive victims are quiet and timid when attacked or insulted and withdraw rather than retaliate. To date, there has been no evidence-based evaluative study examining interventions designed specifically to reduce aggressive victimization, and neither has there been an inclusive assessment screening of high-risk aggressive victims prior to intervention. This study addressed these research gaps by employing multi-stage assessment procedures and a mixed-mode methodology in a one-year longitudinal design. Data were collected from student self-reports, parent and teacher rating scales, and individual structured interviews with students, parents and teachers. A total of 269 potential high-risk aggressive victims were identified from among 5,089 schoolchildren, 68 of whom were screened out and randomly assigned to 10 treatment groups, with 39 completing a one-year follow-up study. Multivariate analysis of variance identified significant improvements in physical and verbal victimization (F(2,47, 93.99) = 10.73, p < 0.01), verbal victimization (F(2.74, 104.14) = 12.80, p < 0.01) and social exclusion scores at the three follow-up assessments compared to the pre-treatment scores, and the qualitative results were consistent, showing participants' cognition, emotion, and behavior to have been positively reconstructed by the group intervention. The consistent quantitative and qualitative results confirm that the cognitive-behavioral group therapy program reported herein is effective in reducing aggressive victims' anxious and depressed emotions and reactive cognition. © 2012 The Author.

The purpose of this study was to examine whether homeless or vulnerably housed individuals experienced response shift over a 12-month time period in their self-reported physical and mental health status. Data were obtained from the Health and Housing in Transition study, a longitudinal multi-site cohort study in Canada (N = 1190 at baseline). Multi-group confirmatory factor analysis (MG-CFA) and methods for response shift detection at the item level, based on the approach by Oort, were used to test for reconceptualization, reprioritization, and recalibration response shift on the SF-12 in four groups of individuals who were homeless (n = 170), housed (n = 437), or who reported a change in their housing status [from homeless to housed (n = 285) or housed to homeless (n = 73)] over a 12-month time period. Mean and variance adjusted weighted-least squares estimation was used to accommodate the ordinal and binary distributions of the SF-12 items. Using MG-CFA, a strict invariance model showed that the measurement model was equivalent for the four groups at baseline. Although we found small but statistically significant response shift for several measurement model parameters, the impact on the predicted average mental and physical health scores within each of the groups was small. Response shift does not appear to be a significant concern when using the SF-12 to obtain change scores over a 12-month period in this population.

We investigated tenant healthcare utilisation associated with upgrading 8558 council houses to a national quality standard. Homes received multiple internal and external improvements and were analysed using repeated measures of healthcare utilisation. The primary outcome was emergency hospital admissions for cardiorespiratory conditions and injuries for residents aged 60 years and over. Secondary outcomes included each of the separate conditions, for tenants aged 60 and over, and for all ages. Council home address and intervention records for eight housing cointerventions were anonymously linked to demographic data, hospital admissions and deaths for individuals in a dynamic cohort. Counts of health events were analysed using multilevel regression models to investigate associations between receipt of each housing improvement, adjusting for potential confounding factors and regional trends. Residents aged 60 years and over living in homes when improvements were made were associated with up to 39% fewer admissions compared with those living in homes that were not upgraded (incidence rate ratio=0.61, 95% CI 0.53 to 0.72). Reduced admissions were associated with electrical systems, windows and doors, wall insulation, and garden paths. There were small non-significant reductions for the primary outcome associated with upgrading heating, adequate loft insulation, new kitchens and new bathrooms. Results suggest that hospital admissions can be avoided through improving whole home quality standards. This is the first large-scale longitudinal evaluation of a whole home intervention that has evaluated multiple improvement elements using individual-level objective routine health data. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2013-09-01

Transmission of aggressive behaviors to children through modeling by adults has long been a commonly held psychological concept; however, with the advent of technological innovations during the last 30 years, video media-television, movies, video games, and the Internet-has become the primary model for transmitting aggressiveness to children. This review explores the acquisition of aggressive behaviors by children through modeling behaviors in violent video media. The impact of aggressive behaviors on the child, the family, and society is addressed. Suggestive action plans to curb this societal ill are presented.

Caregivers in nursing homes often experience aggressive behavior of residents. The aim of this study was to explore the caregivers' experiences with aggressive behavior from residents and to identify environmental factors as well as caregiver and resident characteristics related to aggressive behavior in Swiss nursing homes. A retrospective cross-sectional survey was conducted between November 2010 and April 2011 with a sample of caregivers working in various nursing homes in the German-speaking part of Switzerland. In total, 814 caregivers (response rate 51.8%) of 21 nursing homes participated in the study. Data were collected using the German version of the Survey of Violence Experienced by Staff (SOVES-G-R). Standard descriptive statistics were used to describe and summarize the date. To identify risk factors related to the experience of aggression by residents, multilevel logistic regression analysis was applied. The prevalence of participants reporting an aggressive incident during the 12-month period prior to data collection was 81.6%. Of these, 76.5% had experienced verbal aggression, 27.6% threats, and 54.0% physical aggression. The predictive variables in the multiple regression model for physical aggression were: staff education level (odds ratio [OR]= 1.82), gender (OR = 1.82), age (< 30 years vs. 30-45 years: OR = 1.46; < 30 years vs. > 45 years: OR = 2.13), and confidence in managing physical aggression (OR = 1.49). The predictive variables for threatening behavior were staff education level (registered nurses vs. non-registered nurses: OR = 1.70; nonstudent vs. student: OR = 1.89) and age (< 30 years vs. 30-45 years: OR = 2.00; < 30 years vs. > 45 years: OR = 2.04). Caregivers in nursing homes are at high risk for experiencing aggressive behavior. The identified risk factors are in line with earlier investigations, but some contradictory results also were observed. The high risk for registered nurses exposed to aggressive behavior and the increased

Hemorrhagic shock requires early aggressive treatment, including transfusion of packed red blood cells and hemostatic resuscitation. In austere environments, when component therapy is not available, warm fresh whole-blood transfusion is a convenient treatment. It provides red blood cells, clotting factors, and functional platelets. Therefore it is commonly used in military practice to treat hemorrhagic shock in combat casualties. At Bouffard Hospital Center in Djibouti, the supply of packed red blood cells is limited, and apheresis platelets are unavailable. We used whole blood transfusion in two civilian patients with life-threatening non-traumatic hemorrhages. One had massive bleeding caused by disseminated intravascular coagulation due to septic shock; the second was a 39 year-old pregnant woman with uterine rupture. In both cases, whole blood transfusion (twelve and ten 500 mL bags respectively), combined with etiological treatment, enabled coagulopathy correction, hemorrhage control, and satisfactory recovery.

Aggressive behaviour in adolescent psychiatric settings: what are risk factors, possible interventions and implications for nursing practice? A literature review.

2009-09-01

This study was aimed to identify the risk factors of aggressive behaviour in adolescents (1318 years), and to describe available intervention strategies. The findings are evaluated on the basis of their implications for nursing practice. Aggressive behaviour in adolescent psychiatric settings is a neglected research area. The consequences of aggressive behaviour on nurses, other patients and the therapeutic environment can be profound. For the development and implementation of innovative intervention strategies aimed at preventing aggressive behaviour in adolescent psychiatric patients, knowledge of risk factors and evidence-based interventions for aggressive behaviour are of the utmost importance. A systematic search of PubMed, Cinahl, PsychINFO and Cochrane Systematic Reviews (19912007) was employed. The risk factors for aggressive behaviour comprise personal and environmental risk factors. Some risk factors can be influenced by nursing intervention strategies. Available intervention programmes range from interpersonal skills training to massage therapy, parent management training, functional family therapy and multi-systemic therapy. The most effective programmes combine interpersonal skills training with parent management training. No specific nursing intervention programmes were found for dealing with aggressive behaviour in adolescent patients. Nursing staff can assist in achieving a systematic improvement in the treatment outcomes of existing intervention programmes for the prevention of aggression. There is a need for specific nursing intervention programmes to deal with aggressive behaviour in adolescent psychiatric settings.

2015-03-01

Existing research on aggression tends to narrowly focus on peers; less is known about sibling aggression, most likely due to its historical acceptance. Aggression is characterized by its forms (i.e., physical vs. social or relational aggression) and its functions (i.e., the motivations behind the aggressive act and categorized as proactive vs. reactive aggression). We use data from a two-wave study of middle (n = 197; M age = 12.63 years at Wave 1) and older (n = 159; M age = 16.50 years at Wave 1) adolescents to assess the extent to which proactive and reactive functions of sibling aggression make unique or conditional contributions to adolescent adjustment (i.e., depression, delinquency, and substance use). We find that proactive sibling aggression increases risk for problem substance use and delinquent behavior, reactive sibling aggression increases risk for depressed mood and delinquent behavior, and such results are observed even with statistical adjustments for sociodemographic and family variables, stressful life events, and prior adjustment. Few conditional effects of proactive or reactive sibling aggression by sex or grade are observed; yet, for all three outcomes, the harmful effects of reactive sibling aggression are strongest among adolescents who report low levels of proactive sibling aggression. The results speak to the importance of understanding the proactive and reactive functions of sibling aggressive behaviors for adolescent adjustment. © The Author(s) 2014.

Is Housing a Health Insult?

PubMed Central

Baker, Emma; Beer, Andrew; Lester, Laurence; Pevalin, David; Whitehead, Christine; Bentley, Rebecca

2017-01-01

In seeking to understand the relationship between housing and health, research attention is often focussed on separate components of people’s whole housing ‘bundles’. We propose in this paper that such conceptual and methodological abstraction of elements of the housing and health relationship limits our ability to understand the scale of the accumulated effect of housing on health and thereby contributes to the under-recognition of adequate housing as a social policy tool and powerful health intervention. In this paper, we propose and describe an index to capture the means by which housing bundles influence health. We conceptualise the index as reflecting accumulated housing “insults to health”—an Index of Housing Insults (IHI). We apply the index to a sample of 1000 low-income households in Australia. The analysis shows a graded association between housing insults and health on all outcome measures. Further, after controlling for possible confounders, the IHI is shown to provide additional predictive power to the explanation of levels of mental health, general health and clinical depression beyond more traditional proxy measures. Overall, this paper reinforces the need to look not just at separate housing components but to embrace a broader understanding of the relationship between housing and health. PMID:28587139

Moderating effects of family environment on the association between children's aggressive beliefs and their aggression trajectories from childhood to adolescence.

PubMed

Andreas, Jasmina Burdzovic; Watson, Malcolm W

2009-01-01

This study explored how children's aggressive beliefs and their family environments combine to influence the development of child aggression from middle childhood into adolescence. We utilized a "variable-centered" empirical approach, specifically examining whether children's aggressive beliefs represent a risk factor for their aggressive behaviors and whether this risk can be moderated by children's family environment. These questions were tested with individual growth modeling, using the data from a community-representative sample of 440 mother-child dyads, interviewed four times over a 6-year study period. The accelerated longitudinal design of the study enabled examination of children's aggression trajectories from age 7 to age 19. The results supported the hypothesis that elevated aggressive beliefs in children represent a risk factor for aggression, as higher aggressive beliefs were associated with greater aggression at the youngest age, as well as with increased aggression over time. However, as hypothesized, family environment moderated this association, such that changes in children's aggression over time were contingent upon the interaction of their aggressive beliefs with family environment. Specifically, aggression was reduced in children with high aggressive beliefs if they experienced better than average family environment, which included less family conflict and more family cohesion.

Aggression is a violent behavior emitted against another organism that may lead to its harm or death and thus is of public health significance, which necessitates the search for agents with anti-aggressive property. This study investigated the effect of Jobelyn® (JB), a unique African polyherbal formulation, on intruder- and isolation-induced aggressive behaviors in mice. Male mice that showed aggression after being housed individually with female counterparts for 3 weeks or kept in isolation for 4 weeks were treated orally (p.o.) with JB (5, 10 or 50 mg/kg), haloperidol (HP) (1 mg/kg), fluoxetine (FL) (10 mg/kg), p-chlorophenylalanine (PCPA) (20 mg/kg), mianserin (MS) (50 mg/kg) or distilled water (10 mL/kg) 60 min before being tested for aggression. Interaction studies involving oral administration of PCPA (20 mg/kg), FL (10 mg/kg) or MS (50 mg/kg) to aggressive mice that had received JB (5 or 10 mg/kg, p.o.) 30 min earlier were assessed. The effect of JB (5, 10 or 50 mg/kg, p.o.) on defensive behaviors was also evaluated. JB (5, 10 or 50 mg/kg) decreased aggressive behaviors without impairing the defensive mechanisms of mice. PCPA (20 mg/kg), an inhibitor of 5-hydroxytryptamine (5-HT) biosynthesis, increased aggressive responses and reduced the anti-aggressive effect of JB. FL (10 mg/kg), a 5-HT reuptake inhibitor, significantly suppressed aggression but did not alter the effect of JB on aggression. MS (50 mg/kg), a 5-HT receptor antagonist, reduced aggression and enhanced the effect of JB on aggression. These findings suggest that JB has anti-aggressive activity, which may be related to the enhancement of serotonergic system.

Skin conductance fear conditioning impairments and aggression: a longitudinal study.

PubMed

Gao, Yu; Tuvblad, Catherine; Schell, Anne; Baker, Laura; Raine, Adrian

2015-02-01

Autonomic fear conditioning deficits have been linked to child aggression and adult criminal behavior. However, it is unknown if fear conditioning deficits are specific to certain subtypes of aggression, and longitudinal research is rare. In the current study, reactive and proactive aggression were assessed in a sample of males and females when aged 10, 12, 15, and 18 years old. Skin conductance fear conditioning data were collected when they were 18 years old. Individuals who were persistently high on proactive aggression measures had significantly poorer conditioned responses at 18 years old when compared to others. This association was not found for reactive aggression. Consistent with prior literature, findings suggest that persistent antisocial individuals have unique neurobiological characteristics and that poor autonomic fear conditioning is associated with the presence of increased instrumental aggressive behavior. © 2014 Society for Psychophysiological Research.

Life Course Associations between Victimization and Aggression: Distinct and Cumulative Contributions

Logan-Greene, Patricia; Nurius, Paula S.; Hooven, Carole; Thompson, Elaine Adams

2014-01-01

The connections between early maltreatment and later aggression are well established in the literature, however gaps remain in our understanding of developmental processes. This study investigates the cascading lifecourse linkages between victimization experiences from childhood through early adulthood andlater aggressive behavior. The diverse, at-risk sample is of particular importance to child and adolescent specialists, as it represents highly vulnerable youth accessible through conventional school settings. In addition to direct pathways from proximal life periods, path analysis revealed significant indirect mediated pathways through which earlier life victimizationcontributes to aggressive behaviors in later life periods as well as revictimization. Multivariateregressions support theorized cumulative effects of multi-form victimization as well as distinct contributions of victimization domains (emotional, witnessing, physical, property, and sexual) in explaining aggressive behavior.Consistent with theorizing about the developmental impact of early maltreatment, results bolster the importance of interrupting pathways from victimization to revictimization and later aggression. Findings are evaluated in light of implications for early identification and prevention programming. PMID:26190899

Psychopharmacological treatment of aggression in schizophrenic patients.

PubMed

Brieden, T; Ujeyl, M; Naber, D

2002-05-01

Aggressive behavior is frequently observed in schizophrenic patients. More than 50 % of all psychiatric patients and 10 % of schizophrenic patients show aggressive symptoms varying from threatening behavior and agitation to assault. The pharmacological treatment of acute, persisting and repetitive aggression is a serious problem for other patients and staff members. Not only is violent behavior from mentally ill patients the most detrimental factor in their stigmatization, aggression is also a considerable direct source of danger for the patients themselves. Based on rather limited evidence, a wide variety of medications for the pharmacological treatment of aggression has been recommended: typical and atypical antipsychotics, benzodiazepines, mood stabilizers, beta-blockers and selective serotonin reuptake inhibitors (SSRIs). Most clinical information on treating aggression has been collected for atypical neuroleptics, particularly for clozapine. Several retrospective and open studies indicate its efficacy. Treatment duration of 6 months is recommended to induce a stable reduction of physical and verbal aggression. Severe side effects have very rarely been seen. At the moment, clozapine seems to be the first choice in aggression treatment. Within the last few years, about 10 articles were published showing that this is the most effective antiaggressive agent in the treatment of aggression and agitation in psychiatric patients, independent of psychiatric diagnosis. However, clozapine, like all the other substances used, does not have an established indication for the treatment of aggressive symptoms. Noncompliance with medication makes it difficult to choose the right preparation for the medication: tablets, liquids, intramuscular injections and readily soluble "FDDFs" are available. Ethical, juridical and methodological problems prevent controlled studies from establishing a reference in the treatment of aggression in mentally ill patients. This review summarizes

Toward a refined view of aggressive fantasy as a risk factor for aggression: interaction effects involving cognitive and situational variables.

PubMed

Smith, Craig E; Fischer, Kurt W; Watson, Malcolm W

2009-01-01

Over three decades of research have established a positive connection between fantasizing about aggression and enacting aggression. Such findings have provided strong evidence against the catharsis view of aggressive fantasy. However, little attention has been paid to the potentially nuanced nature of the link between fantasy aggression and actual aggression. In the present article, we examined the influence of four variables in the aggressive fantasy-aggressive behavior link: gender, exposure to violence, fantasy absorption, and level of fantasy about harm befalling loved ones and the self (dysphoric fantasy). Using data from a diverse, community-based sample of 7-14-year olds and their mothers, we replicated the general finding that aggressive fantasy is positively associated with real-world aggressive behavior. However, we also found that the interaction of aggressive fantasy and exposure to violence related significantly to aggression, as did the relation between aggressive fantasy and dysphoric fantasy. When exposure to violence was low, even high levels of aggressive fantasizing did not predict aggressive behavior, and, when aggressive fantasizing was low, even high levels of exposure to violence did not predict aggressive behavior. Similarly, when dysphoric fantasy was high, the connection between fantasy aggression and real aggression was markedly attenuated. The implications of these findings for intervention efforts and future research are considered. Copyright 2009 Wiley-Liss, Inc.

Relations between parental psychological control and childhood relational aggression: reciprocal in nature?

2009-01-01

Using a cross-lagged panel design, this study examined the directionality of relations between parental psychological control and child relational aggression. Data were collected from a proportionally stratified sample of 600 Flemish 8- to 10-year-old children at 3 measurement points with 1-year intervals. Reciprocal effects were evident in mother-child dyads. Maternal psychological control was positively related to child relational aggression 1 year later, and child relational aggression was positively related to maternal psychological control 1 year later. The father-child dyads were best represented by unidirectional parent effects. Paternal psychological control was positively related to child relational aggression 1 year later. Surprisingly, these effects emerged only for relational aggression as indexed by mother and father reports and not for relational aggression as indexed by teacher and peer measures.

Chronic lead exposure is associated with neurological ill-health including anti-social behavior such as aggressive behavior. The main aim of this study was to examine the association between lead exposure at 13years old and dimensions of aggressive behavior during mid-adolescence. The study sample included 508 males and 578 females in mid-adolescence (age 14 to 15years) from the Birth to Twenty Plus cohort in Johannesburg, South Africa. Blood samples collected at age 13years were used to measure blood lead levels. Seventeen items characterizing aggression from the Youth Self Report questionnaire were used to examine aggressive behavior. Principal Component Analysis was used to derive composite variables from the original data for aggressive behavior; and data were examined for an association between blood lead levels and dimensionality of direct and indirect aggression and disobedience during mid-adolescence. We also examined the dimensions of aggression during mid-adolescence in relation to gender and socio-demographic factors. Blood lead levels ranged from 1 to 28.1μg/dL. Seventy two percent of males and 47.7% of females in the study had blood lead levels ≥5μg/dL. There was a positive association between elevated blood lead levels and direct aggression (p<0.05). Being male was positively associated with direct aggression (p<0.001) but, negatively associated with indirect aggression (p<0.001). Maternal education and age at birth were negatively associated with direct aggression during mid-adolescence. The significant association between elevated blood lead levels and direct aggressive behavior observed in this study may shed light on a possible environmental toxicological contribution to aggressive behavior in South African youth; and most importantly the type of aggressive behavior associated to lead exposure.

Although research on the relation between testosterone and aggression in humans is inconclusive, guidelines (including the World Professional Association for Transgender Health Standards of Care, edition 7) have warned for an increase in aggression in transgender men taking testosterone treatment. To investigate the association between levels of testosterone and aggression in treatment-seeking transgender people and explore the role of mental health psychopathology (anxiety and depressive symptoms) and social support in aggression in this population. Every transgender person invited for assessment at a national transgender health clinic in the United Kingdom during a 3-year period (2012-2015) completed self-report measures for interpersonal problems, including levels of aggression (Inventory of Interpersonal Problems [IIP-32]), symptoms of anxiety and depression (Hospital Anxiety and Depression Scale [HADS]), social support (Multidimensional Scale of Perceived Social Support), and experiences of transphobia before and 1 year after the initiation of gender-affirming hormonal therapy. Correlations between prospective scores for the IIP-32 factor "too aggressive" and prospective levels of sex steroids, prospective psychological (HADS), and baseline psychosocial measurements were tested. Prospective scores for the factor "too aggressive" were not correlated to prospective serum testosterone levels. Results of 140 people (56 transgender men, 84 transgender women) were analyzed. A prospective increase in scores for the factor "too aggressive" of the IIP-32 in transgender men 1 year after being treated with testosterone treatment or a decrease of the IIP-32 aggression scores in transgender women 1 year after gender-affirming hormonal therapy was not found. However, a positive correlation was found between increasing HADS anxiety scores and increasing scores for the IIP-32 "too aggressive" score in the entire study population and a positive correlation with lower support

Behavioral characterization of escalated aggression induced by GABAB receptor activation in the dorsal raphé nucleus

2013-01-01

Rationale Pharmacological activation of GABAB receptors in the dorsal raphé nucleus (DRN) can escalate territorial aggression in male mice. Objectives We characterized this escalated aggression in terms of its behavioral and environmental determinants. Methods Aggressive behavior of resident male (CFW or ICR mouse) was assessed in confrontations with a group-housed intruder. Either baclofen (0.06 nmol/0.2 μl) or vehicle (saline) was microinjected into the DRN ten minutes before the confrontation. We examined baclofen-heightened aggression in five situations: aggression in a neutral arena and after social instigation (experiment 1), aggression during the light phase of the cycle (experiment 2), aggression without prior fighting experience (experiment 3), aggression toward a female (experiment 4), and aggression after defeat experiences (experiment 5). In addition, we examined the body targets towards which bites are directed and the duration of aggressive bursts after baclofen treatment. Results Regardless of the past social experience, baclofen escalated aggressive behaviors. Even in the neutral arena and after defeat experiences, where aggressive behaviors were inhibited, baclofen significantly increased aggression. Baclofen increased attack bites directed at vulnerable body areas of male intruders but not toward a female and only in the dark. Also, baclofen prolonged the duration of aggressive bursts. Conclusions For baclofen to escalate aggression, specific stimulation (male intruder) and tonic level of serotonin (dark cycle) are required. Once aggressive behavior is triggered, intra-DRN baclofen escalates the level of aggression to abnormal levels and renders it difficult to terminate. Also, baclofen counteracts the effects of novelty or past experiences of defeat. PMID:22395428

2015-07-28

We tested a model that children's tendency to attribute hostile intent to others in response to provocation is a key psychological process that statistically accounts for individual differences in reactive aggressive behavior and that this mechanism contributes to global group differences in children's chronic aggressive behavior problems. Participants were 1,299 children (mean age at year 1 = 8.3 y; 51% girls) from 12 diverse ecological-context groups in nine countries worldwide, followed across 4 y. In year 3, each child was presented with each of 10 hypothetical vignettes depicting an ambiguous provocation toward the child and was asked to attribute the likely intent of the provocateur (coded as benign or hostile) and to predict his or her own behavioral response (coded as nonaggression or reactive aggression). Mothers and children independently rated the child's chronic aggressive behavior problems in years 2, 3, and 4. In every ecological group, in those situations in which a child attributed hostile intent to a peer, that child was more likely to report that he or she would respond with reactive aggression than in situations when that same child attributed benign intent. Across children, hostile attributional bias scores predicted higher mother- and child-rated chronic aggressive behavior problems, even controlling for prior aggression. Ecological group differences in the tendency for children to attribute hostile intent statistically accounted for a significant portion of group differences in chronic aggressive behavior problems. The findings suggest a psychological mechanism for group differences in aggressive behavior and point to potential interventions to reduce aggressive behavior.

Predicting aggression in children with ADHD

PubMed Central

2014-01-01

Objective The present study uses structural equation modeling of latent traits to examine the extent to which family factors, cognitive factors and perceptions of rejection in mother-child relations differentially correlate with aggression at home and at school. Methods Data were collected from 476 school-age (7–15 years old) children with a diagnosis of ADHD who had previously shown different types of aggressive behavior, as well as from their parents and teachers. Structural equation modeling was used to examine the differential relationships between maternal rejection, family, cognitive factors and aggression in home and school settings. Results Family factors influenced aggression reported at home (.68) and at school (.44); maternal rejection seems to be related to aggression at home (.21). Cognitive factors influenced aggression reported at school (.-05) and at home (-.12). Conclusions Both genetic and environmental factors contribute to the development of aggressive behavior in ADHD. Identifying key risk factors will advance the development of appropriate clinical interventions and prevention strategies and will provide information to guide the targeting of resources to those children at highest risk.

2018-05-01

To the authors' knowledge, the survival benefit of local therapy in the setting of advanced prostate cancer remains unknown. The authors investigated whether prostate-directed treatment with either surgery or radiotherapy versus conservative treatment in the setting of locally advanced or metastatic disease was associated with improved survival within a cohort of men from the Centers for Disease Control and Prevention's (CDC) Breast and Prostate Cancer Data Quality and Patterns of Care Study (CDC POC-BP). Men diagnosed with locally advanced (cT3-T4 or N+ and M0) or metastatic prostate cancer were identified. The authors compared survival by treatment type, categorized as conservative (androgen deprivation therapy only) versus aggressive (radical prostatectomy or any type of radiotherapy). Nine-year overall survival and prostate cancer-specific survival were estimated using the Kaplan-Meier method. The Cox proportional hazards model was used to determine factors independently associated with 9-year prostate cancer-specific survival. For men with advanced, nonmetastatic prostate cancer, conservative treatment alone was associated with a 4 times higher likelihood of prostate cancer mortality compared with men treated with surgery (hazard ratio, 4.18; 95% confidence interval, 1.44-12.14). In contrast, no difference was found between conservative versus aggressive treatment after adjusting for covariates for men with metastatic disease. The 9-year prostate cancer-specific survival rate was 27% for those receiving aggressive treatment versus 24% for men undergoing conservative treatment. The authors did not observe a survival advantage with local therapy in addition to standard androgen deprivation therapy for men with metastatic prostate cancer. However, the results of the current study did affirm advantages in the setting of locally advanced disease. Aggressive local therapy in the setting of metastatic disease needs to be studied carefully before clinical adoption

Everyday marital conflict and child aggression.

PubMed

Cummings, E Mark; Goeke-Morey, Marcie C; Papp, Lauren M

2004-04-01

Children's immediate aggressive responding to exposure to marital conflict was examined. Participants were 108 families with 8- to 16-year-old children (53 boys, 55 girls), with diary records of children's reactions to marital conflict in the home completed by 103 mothers (n = 578 records) and 95 fathers (n = 377 records) during a 15-day period. Child responses to analog presentations of marital conflict tactics were also obtained. Exposure to destructive conflict tactics and negative parental emotionality increased the likelihood of aggressive behavior in children when they witnessed marital conflict, whereas constructive conflict tactics and positive parental emotionality decreased the probability of aggression. Conflict topics presumed to be threatening to the child (child- or marital-related) also heightened the likelihood of aggression. Aggressive responding to conflict in both home and laboratory predicted externalizing behavior problems. Fathers' and mothers' separate diary reports, and child responses to analog presentation of conflict, provided generally consistent findings. An exposure hypothesis for marital conflict as an influence on child aggression is discussed.

Neural mediators of the intergenerational transmission of family aggression

2015-01-01

Youth exposed to family aggression may become more aggressive themselves, but the mechanisms of intergenerational transmission are understudied. In a longitudinal study, we found that adolescents’ reduced neural activation when rating their parents’ emotions, assessed via magnetic resonance imaging, mediated the association between parents’ past aggression and adolescents’ subsequent aggressive behavior toward parents. A subsample of 21 youth, drawn from the larger study, underwent magnetic resonance imaging scanning proximate to the second of two assessments of the family environment. At Time 1 (when youth were on average 15.51 years old) we measured parents’ aggressive marital and parent–child conflict behaviors, and at Time 2 (≈2 years later), we measured youth aggression directed toward parents. Youth from more aggressive families showed relatively less activation to parent stimuli in brain areas associated with salience and socioemotional processing, including the insula and limbic structures. Activation patterns in these same areas were also associated with youths’ subsequent parent-directed aggression. The association between parents’ aggression and youths’ subsequent parent-directed aggression was statistically mediated by signal change coefficients in the insula, right amygdala, thalamus, and putamen. These signal change coefficients were also positively associated with scores on a mentalizing measure. Hypoarousal of the emotional brain to family stimuli may support the intergenerational transmission of family aggression. PMID:26073067

One-year housing arrangements among homeless adults with serious mental illness in the ACCESS program.

PubMed

Mares, Alvin S; Rosenheck, Robert A

2004-05-01

This study examined the various living arrangements among formerly homeless adults with mental illness 12 months after they entered case management. The study surveyed 5,325 clients who received intensive case management services in the Access to Community Care and Effective Services and Supports (ACCESS) program. Living arrangements 12 months after program entry were classified into six types on the basis of residential setting, the presence of others in the home, and stability (living in the same place for 60 days). Differences in perceived housing quality, unmet housing needs, and overall satisfaction were compared across living arrangements by using analysis of covariance. One year after entering case management, 37 percent of clients had been independently housed during the previous 60 days (29 percent lived alone in their own place and 8 percent lived with others in their own place), 52 percent had been dependently housed during the previous 60 days (11 percent lived in someone else's place, 10 percent lived in an institution, and 31 percent lived in multiple places), and 11 percent had literally been homeless during the previous 60 days. Clients with less severe mental health and addiction problems at baseline and those in communities that had higher social capital and more affordable housing were more likely to become independently housed, to show greater clinical improvement, and to have greater access to housing services. After the analysis adjusted for potentially confounding factors, independently housed clients were more satisfied with life overall. However, no significant association was found between specific living arrangements and either perceived housing quality or perceived unmet needs for housing. Living independently was positively associated with satisfaction of life overall, but it was not associated with the perception that the quality of housing was better or that there was less of a need for permanent housing.

2013-01-01

This study's objective is to analyze temperament and parenting variables as they relate to proactive and reactive aggression in children. To be specific, profiles based on these variables were analyzed in children with high levels of proactive versus reactive aggression. The sample was made up of two groups: 482 children (52.3% boys) between 1 and 3 years-old, and 422 children (42.42% boys) 3 to 6 years-old. Statistical analyses of the two age groups included: Pearson's correlations to explore the relationships among variables, Cluster Analysis to create groups with different levels of aggression, and finally discriminant analysis to determine which variables discriminate between groups. The results show that high levels of frustration/negative affect in the 1-3 year-old group and low effortful control in children 3 to 6 years old are the most relevant variables in differentiating between aggressive and non-aggressive subjects. Nevertheless, differential profiles of subjects with high levels of proactive versus reactive aggression were not observed. The implications of these different types of aggression in terms of development and prevention are discussed.

Several authors consider high and frequent conflicts between friends during childhood as a serious risk for subsequent conduct problems such as generalized physical aggression toward others (e.g., Kupersmidt, Burchinal, & Patterson, 1995; Sebanc, 2003). Although it seems logical to assume that friendship conflict could have some negative consequences on children's behaviors, some scholars have suggested that a certain amount of conflict between friends may actually promote social adjustment (e.g., Laursen & Pursell, 2009). The aim of this study was to investigate the role of friendship conflict in regard to the development of generalized physical aggression toward others in the early school years (i.e., from kindergarten to Grade 1), as well as the moderating role of relational (i.e., shared positive affect and dyadic conflict resolution skills) and personal (i.e., children's sex and genetic liability for aggression) characteristics in this context. The sample included 745 twins assessed through teacher, peer, child, and friend ratings in kindergarten and Grade 1. Friendship conflict in kindergarten was linearly related to an increase in boys' but not girls' generalized physical aggression. However, shared positive affect and conflict resolution skills mitigated the prospective associations between friendship conflict and generalized physical aggression. These results were independent of children's sex, genetic risk for physical aggression, and initial levels of generalized physical aggression in kindergarten. Fostering a positive relationship between friends at school entry may buffer against the risk associated with experiencing friendship conflict.

The Relational Neurobehavioral Approach (RNA) is a set of non-aversive intervention methods to manage individuals with brain injury-related aggression. New data on interventions used in the RNA and on how the RNA interventions can be used with patients with acquired brain injury (ABI) who have differing levels of functional impairment are provided in this paper. The study was conducted over a 6-week period in a secure 65-bed program for individuals with ABI that is housed in two units of a skilled nursing facility (SNF). Implementation of the RNA was compared between two units that housed patients with differing levels of functional impairment (n = 65 adults). Since this was a hierarchical clustered dataset, Generalized Estimating Equations regression was used in the analyses. RNA interventions used to manage the 495 aggressive incidents included the following: Aggression ignored, Closer observation, Talking to patient, Reassurance, Physical distraction, Isolation without seclusion, Immediate medication by mouth, Holding patient. Different interventions were implemented differentially by staff based on level of functional impairment and without use of seclusion or mechanical restraint. The RNA can be used to non-aversively manage aggression in patients with brain injury and with differing levels of functional impairment. Programs adopting the RNA can potentially manage brain injury-related aggression without seclusion or mechanical restraint. Implications for Rehabilitation The Relational Neurobehavioral Approach (RNA) is a set of non-aversive intervention methods to manage individuals with brain injury-related aggression. RNA methods can be used to manage aggression in patients with brain injury who have differing levels of functional impairment. Successful implementation of the RNA may allow for the management of brain injury-related aggression without seclusion or mechanical restraint.

The primary aim of the current article was the evaluation of the factorial composition of the Aggression Questionnaire (AQ(29)) in the Greek population. The translated questionnaire was administered to the following three heterogeneous adult samples: a general population sample from Athens, a sample of young male conscripts and a sample of individuals facing problems related to substance use. Factor analysis highlighted a structure similar to the one proposed by Buss and Perry [Buss, A.F., Perry, M., 1992. The Aggression Questionnaire. Journal of Personality and Social Psychology 63, 452-459]. However, the refined 12-item version of Bryant and Smith [Bryant, F.B., Smith, B.D., 2001. Refining the architecture of aggression: a measurement model for the Buss-Perry Aggression Questionnaire. Journal of Research in Personality 35, 138-167] provided a better fit to our data. Therefore, the refined model was implemented in further analysis. Multiple group confirmatory factor analysis was applied in order to assess the variability of the 12-item AQ across gender and samples. The percentage of factor loading invariance between males and females and across the three samples defined above was high (higher than 75%). The reliability (internal consistency) of the scale was satisfactory in all cases. Content validity of the 12-item AQ was confirmed by comparison with the Symptom Check-List 90 Revised.

Using data from two American and one Finnish long-term longitudinal studies, we examined continuity of general aggression from age 8 to physical aggression in early adulthood (age 21–30) and whether continuity of aggression differed by country, sex, and parent occupational status. In all samples, childhood aggression was assessed via peer nominations and early adulthood aggression via self-reports. Multi-group structural equation models revealed significant continuity in aggression in the American samples but not in the Finnish sample. These relations did not differ by sex but did differ by parent occupational status: whereas there was no significant continuity among American children from professional family-of-origin backgrounds, there was significant continuity among American children from non-professional backgrounds.

Purpose To investigate whether parents’ previous physical aggression (PPA) exhibited during early adolescence is associated with adolescents’ subsequent parent-directed aggression even beyond parents’ concurrent physical aggression (CPA); to investigate whether adolescents’ emotion dysregulation and attitudes condoning child-to-parent aggression moderate associations. Methods Adolescents (N = 93) and their parents participated in a prospective, longitudinal study. Adolescents and parents reported at waves 1–3 on four types of parents’ PPA (mother-to-adolescent, father-to-adolescent, mother-to-father, father-to-mother). Wave 3 assessments also included adolescents’ emotion dysregulation, attitudes condoning aggression, and externalizing behaviors. At waves 4 and 5, adolescents and parents reported on adolescents’ parent-directed physical aggression, property damage, and verbal aggression, and on parents’ CPA Results Parents’ PPA emerged as a significant indicator of adolescents’ parent-directed physical aggression (odds ratio [OR]: 1.25, 95% confidence interval [CI]: 1.0–1.55; p = .047), property damage (OR: 1.29, 95% CI: 1.1–1.5, p = .002), and verbal aggression (OR: 1.35, 95% CI: 1.15–1.6, p < .001) even controlling for adolescents’ sex, externalizing behaviors, and family income. When controlling for parents’ CPA, previous mother-to-adolescent aggression still predicted adolescents’ parent-directed physical aggression (OR: 5.56, 95% CI: 1.82–17.0, p = .003), and father-to-mother aggression predicted adolescents’ parent-directed verbal aggression (OR: 1.86, 95% CI: 1.0–3.3, p = .036). Emotion dysregulation and attitudes condoning aggression did not produce direct or moderated effects. Conclusions Adolescents’ parent-directed aggression deserves greater attention in discourse about lasting, adverse effects of even minor forms of parents’ physical aggression. Future research should investigate parent-directed aggression as

A critically appraised topic (CAT) to compare the effects of single and multi-cat housing on physiological and behavioural measures of stress in domestic cats in confined environments.

PubMed

Finka, Lauren R; Ellis, Sarah Lh; Stavisky, Jenny

2014-03-22

Domestic cats have evolved from solitary, asocial predators and whilst they may display social behaviours, they can still exist as solitary survivors. Over-population and relinquishment of pet cats are ubiquitous problems worldwide, and rehoming centres (also known as rescues/ shelters) aim to ameliorate this by holding cats in confinement for a variable period until a new home is found. The provision of optimal housing for large numbers of cats in close confinement, such as in rehoming centres, is therefore inherently difficult. Under these conditions there is the potential for individuals to develop signs of physical and psychological ill health, and thus experience compromised welfare. Available information regarding housing practices that maximise welfare currently provides conflicting results, and as a consequence there are no unanimous housing recommendations. The aim of this study was therefore to review the evidence on the impact of single housing compared to multi-cat housing on stress in confined cats, as measured by physiological and/or behavioural outcomes. The review was conducted using a Critically Appraised Topic (CAT) format. A systematic search of electronic databases (CAB Abstracts, Zoological Records and Medline) was carried out to identify peer-reviewed literature comparing single and multi-cat housing in confined environments. A total of 959 papers were initially identified, six of which met sufficient criteria based on their relevance to be included within this review. All of the studies had significant limitations in design and methodology, including a lack of information on how groups were assigned, inconsistent handling and enrichment provision between groups, and lack of information on the socialisation status of cats. Whilst some studies suggested that single housing may be less stressful for cats, others suggested group housing was less stressful. Several other important factors were however identified as potential mediators of stress

, estimated to comprise ~14% of the sample, followed a rising trajectory of high physical aggression. Best predictors before or at birth of the high physical aggression trajectory group, controlling for the levels of the other risk factors, were having young siblings (odds ratio [OR]: 4.00; confidence interval [CI]: 2.2–7.4), mothers with high levels of antisocial behavior before the end of high school (OR: 3.1; CI: 1.1–8.6), mothers who started having children early (OR: 3.1; CI: 1.4–6.8), families with low income (OR: 2.6; CI: 1.3–5.2), and mothers who smoked during pregnancy (OR: 2.2; CI: 1.1–4.1). Best predictors at 5 months of age were mothers’ coercive parenting behavior (OR: 2.3; CI: 1.1–4.7) and family dysfunction (OR: 2.2; CI: 1.2–4.1). The OR for a high-aggression trajectory was 10.9 for children whose mother reported both high levels of antisocial behavior and early childbearing. Conclusions Most children have initiated the use of physical aggression during infancy, and most will learn to use alternatives in the following years before they enter primary school. Humans seem to learn to regulate the use of physical aggression during the preschool years. Those who do not, seem to be at highest risk of serious violent behavior during adolescence and adulthood. Results from the present study indicate that children who are at highest risk of not learning to regulate physical aggression in early childhood have mothers with a history of antisocial behavior during their school years, mothers who start childbearing early and who smoke during pregnancy, and parents who have low income and have serious problems living together. All of these variables are relatively easy to measure during pregnancy. Preventive interventions should target families with high-risk profiles on these variables. Experiments with such programs have shown long-term impacts on child abuse and child antisocial behavior. However, these impacts were not observed in families with physical

Social determinants of aggression in a sample of Chinese primary school children.

Ekblad, S

1986-05-01

The aim of the present study was to relate children's aggression levels to social determinants of interest (i.e., child-rearing measures, day-care attendance, peer group influence, and TV-watching) in a sample of Chinese children in the People's Republic of China. A sample of 290 primary school students (155 boys and 135 girls, mean age 10.3) in grade four in Beijing were investigated using the Multi-Faceted Aggression Inventory. The children's parents were asked about child-rearing measures and day-care experience for the child. Teachers rated the children's aggression, school achievement level, and membership in the Young Pioneers. Despite acknowledged limitations, the findings in this study gave evidence that according to a person-environment interaction perspective, the Chinese children's individual differences in aggression were influenced by the restricted environment. As aggressive behaviour is undesired and suppressed in the Chinese culture in and outside the home, the Chinese children seemed to show lower levels and less variation of aggression behaviour than children in permissive environments (e.g., Sweden). However, when analysing sex differences in aggression environmental influences alone might not explain the differences.

2018-06-01

A chondroblastoma-like osteosarcoma (CLO) in the proximal epiphysis and metaphysis of the tibia in a 30-year-old male is presented. With a wrong diagnosis of chondroblastoma, an aggressive curettage was performed. Later, the patient refused en-bloc resection. Seven years after surgery, there has been no local recurrence, and the patient is living an ordinary and active life. CLO is a very uncommon and controversial histologic subtype of osteosarcoma that can be misdiagnosed as chondroblastoma and therefore incorrectly treated. However, aggressive curettage with its functional advantages could be a reasonable option in selected cases.

2015-10-01

The perpetration and receipt of electronic aggression have largely been assessed with self-report questionnaires. Using a sample of 573 adolescents, the current study compared the psychometric properties of a peer-nomination measure of electronic aggression and victimization to the more widely used self-report approach. Estimates of the reliability, stability, and concordance of peer- and self-report assessments were adequate, mirroring those from research on aggressive exchanges in school. Analyses of validity and utility revealed that peer-nominations, compared to self-reports, provide overlapping and distinct information on adolescents' social, emotional, and academic adjustment. Overall, these findings provide evidence that peer-nominations are a reliable, valid, and useful means for measuring electronic aggression and victimization. Future work will benefit from their incorporation into multi-method assessments. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

Moderating effects of family environment on the association between children’s aggressive beliefs and their aggression trajectories from childhood to adolescence

ANDREAS, JASMINA BURDZOVIC; WATSON, MALCOLM W.

2009-01-01

This study explored how children’s aggressive beliefs and their family environments combine to influence the development of child aggression from middle childhood into adolescence. We utilized a “variable-centered” empirical approach, specifically examining whether children’s aggressive beliefs represent a risk factor for their aggressive behaviors and whether this risk can be moderated by children’s family environment. These questions were tested with individual growth modeling, using the data from a community-representative sample of 440 mother–child dyads, interviewed four times over a 6-year study period. The accelerated longitudinal design of the study enabled examination of children’s aggression trajectories from age 7 to age 19. The results supported the hypothesis that elevated aggressive beliefs in children represent a risk factor for aggression, as higher aggressive beliefs were associated with greater aggression at the youngest age, as well as with increased aggression over time. However, as hypothesized, family environment moderated this association, such that changes in children’s aggression over time were contingent upon the interaction of their aggressive beliefs with family environment. Specifically, aggression was reduced in children with high aggressive beliefs if they experienced better than average family environment, which included less family conflict and more family cohesion.

Automated diagnosis of Alzheimer's disease with multi-atlas based whole brain segmentations

NASA Astrophysics Data System (ADS)

Luo, Yuan; Tang, Xiaoying

2017-03-01

Voxel-based analysis is widely used in quantitative analysis of structural brain magnetic resonance imaging (MRI) and automated disease detection, such as Alzheimer's disease (AD). However, noise at the voxel level may cause low sensitivity to AD-induced structural abnormalities. This can be addressed with the use of a whole brain structural segmentation approach which greatly reduces the dimension of features (the number of voxels). In this paper, we propose an automatic AD diagnosis system that combines such whole brain segmen- tations with advanced machine learning methods. We used a multi-atlas segmentation technique to parcellate T1-weighted images into 54 distinct brain regions and extract their structural volumes to serve as the features for principal-component-analysis-based dimension reduction and support-vector-machine-based classification. The relationship between the number of retained principal components (PCs) and the diagnosis accuracy was systematically evaluated, in a leave-one-out fashion, based on 28 AD subjects and 23 age-matched healthy subjects. Our approach yielded pretty good classification results with 96.08% overall accuracy being achieved using the three foremost PCs. In addition, our approach yielded 96.43% specificity, 100% sensitivity, and 0.9891 area under the receiver operating characteristic curve.

The aim was to develop a new model to identify residential buildings with higher frequencies of "SBS" than expected, "risk buildings". In 2005, 481 multi-family buildings with 10,506 dwellings in Stockholm were studied by a new stratified random sampling. A standardised self-administered questionnaire was used to assess "SBS", atopy and personal factors. The response rate was 73%. Statistical analysis was performed by multiple logistic regressions. Dwellers owning their building reported less "SBS" than those renting. There was a strong relationship between socio-economic factors and ownership. The regression model, ended up with high explanatory values for age, gender, atopy and ownership. Applying our model, 9% of all residential buildings in Stockholm were classified as "risk buildings" with the highest proportion in houses built 1961-1975 (26%) and lowest in houses built 1985-1990 (4%). To identify "risk buildings", it is necessary to adjust for ownership and population characteristics.

Life Course Associations between Victimization and Aggression: Distinctive and Cumulative Contributions

Logan-Greene, Patricia; Nurius, Paula S.; Hooven, Carole; Thompson, Elaine Adams

2014-01-01

The connections between early maltreatment and later aggression are well established in the literature, however gaps remain in our understanding of developmental processes. This study investigates the cascading life course linkages between victimization experiences from childhood through early adulthood and later aggressive behavior. The diverse, at-risk sample is of particular importance to child and adolescent specialists, as it represents highly vulnerable youth accessible through conventional school settings. In addition to direct pathways from proximal life periods, path analysis revealed significant indirect mediated pathways through which earlier life victimization contributes to aggressive behaviors in later life periods as well as revictimization. Multivariate regressions support theorized cumulative effects of multi-form victimization as well as distinct contributions of victimization domains (emotional, witnessing, physical, property, and sexual) in explaining aggressive behavior. Consistent with theorizing about the developmental impact of early maltreatment, results bolster the importance of interrupting pathways from victimization to revictimization and later aggression. Findings are evaluated in light of implications for early identification and prevention programming. PMID:26190900

Individual and peer group normative beliefs about relational aggression.

2010-01-01

Studies show that children who use relational aggression process social information in unique ways; however, findings have been inconsistent and limited by methodological weaknesses. This short-term longitudinal study examined developmental changes in 245 (49% female; ages 8-13) 3rd through 8th graders' normative beliefs about relational aggression and tested the hypothesis that individual and classroom-level norms predict relational aggression 1 year later. Results showed that the transition to middle school was marked by increased approval of relational aggression, and individual norms predicted future relational aggression. Importantly, a contextual model showed that students in peer groups highly supportive of relational aggression became increasingly aggressive. Findings extend social information processing theories of relational aggression to focus on the role of peer group cognitions.

2017-06-01

This study aimed to assess the reliability and validity of the Chinese version of the Driver Aggression Indicators Scale (DAIS), which measures aggressive driving behaviors. Besides, demographic variables (sex and age) and the big five personality traits were examined as potential impact factors of aggressive driving. A total of 422 participants completed the DAIS, Big Five Personality Inventory (BFPI), and the socio-demographic scale. First, psychometric results confirmed that the DAIS had a stable two-factor structure and acceptable internal consistency. Then, agreeableness and conscientiousness were negatively correlated with hostile aggression and revenge committed by the drivers themselves, while neuroticism was positively correlated with aggressive driving committed by the drivers themselves. Meanwhile, more agreeable drivers may perceive less hostile aggression and revenge. More neurotic drivers may perceive more aggressive warning. Finally, the effects of age and sex on aggressive driving were not same as most studies. We found that older age group perceived and committed more hostile acts of aggression and revenge than younger age groups. Female drivers of 49-60 years perceived more aggressive warnings committed by other drivers. Copyright © 2017 Elsevier Ltd. All rights reserved.

A 25 years experience of group-housed sows–reproduction in animal welfare-friendly systems

PubMed Central

2014-01-01

Since January 1 2013, group housing of sows has been compulsory within the European Union (EU) in all pig holdings with more than ten sows. Sows and gilts need to be kept in groups from 4 weeks after service to 1 week before the expected time of farrowing (Article 3(4) of Directive 2008/120/EC on the protection of pigs). The legislation regarding group housing was adopted already in 2001 and a long transitional period was allowed to give member states and producers enough time for adaptation. Even so, group housing of sows still seems to be uncommon in the EU, and is also uncommon in commercial pig farming systems in the rest of the world. In this review we share our experience of the Swedish 25 years of animal welfare legislation stipulating that sows must be loose-housed which de facto means group housed. The two most important concerns related to reproductive function among group-housed sows are the occurrence of lactational oestrus when sows are group-housed during lactation, and the stress that is associated with group housing during mating and gestation. Field and clinical observations in non-lactating, group-housed sows in Sweden suggest that by making basic facts known about the pig reproductive physiology related to mating, we might achieve application of efficient batch-wise breeding without pharmacological interventions. Group housing of lactating sows has some production disadvantages and somewhat lower productivity would likely have to be expected. Recordings of behavioural indicators in different housing systems suggest a lower welfare level in stalled animals compared with group-housed ones. However, there are no consistent effects on the reproductive performance associated with different housing systems. Experimental studies suggest that the most sensitive period, regarding disturbance of reproductive functions by external stressors, is the time around oestrus. We conclude that by keeping sows according to the pig welfare-friendly Directive 2008

There have been many presentations of thermographic residential building analyses at the past ThermosInse conferences. A number of these papers have dealt with evaluation of insulation voids and more recently a few have described air leakage detection 2,3 during the colder winter months. This paper will focus on the thermographic application in the House Doctor instrumented energy analysis approach as developed by Princeton University. The central theme will be the application to a year-round research or commercial activity. Some of the conditions that could create thermographic problems, as well as techniques that may be used to lessen these difficulties, thereby extending the thermographic "season" is discussed. Our experiences in summer thermography with and without the use of a building pressurization system is also covered.

Genetic and Environmental Stability Differs in Reactive and Proactive Aggression

Tuvblad, Catherine; Raine, Adrian; Zheng, Mo; Baker, Laura A.

2009-01-01

The aim of this study was to examine stability and change in genetic and environmental influences on reactive (impulsive and affective) and proactive (planned and instrumental) aggression from childhood to early adolescence. The sample was drawn from an ongoing longitudinal twin study of risk factors for antisocial behavior at the University of Southern California (USC). The twins were measured on two occasions: ages 9–10 years (N = 1,241) and 11–14 years (N = 874). Reactive and proactive aggressive behaviors were rated by parents. The stability in reactive aggression was due to genetic and nonshared environmental influences, whereas the continuity in proactive aggression was primarily genetically mediated. Change in both reactive and proactive aggression between the two occasions was mainly explained by nonshared environmental influences, although some evidence for new genetic variance at the second occasion was found for both forms of aggression. These results suggest that proactive and reactive aggression differ in their genetic and environmental stability, and provide further evidence for some distinction between reactive and proactive forms of aggression.

Policy Design of Multi-Year Crop Insurance Contracts with Partial Payments

PubMed Central

Chen, Ying-Erh; Goodwin, Barry K.

2015-01-01

Current crop insurance is designed to mitigate monetary fluctuations resulting from yield losses for a specific year. However, yield realization tendency can vary from year to year and may depend on the correlation of yield realizations across years. When the current single-year Yield Protection (YP) and Area Risk Protection Insurance (ARPI) contracts are extended to multiple periods, actuarially fair premium rate is expected to decrease as poor yield realizations in a year can be offset by another year’s better yield realizations. In this study, we first use simulations to demonstrate how significant premium savings are possible when coverage is based on the sum of yields across years rather than on a year-by-year basis. We then describe the design of a multi-year framework of crop insurance and model the insurance using a copula approach. Insurance terms are extended to more than a year and the premium, liability, and indemnity are determined by a multi-year term. Moreover, partial payment is provided at the end of each term to offset the possibility of significant loss in a single term. County-level data obtained from the U.S. Department of Agriculture are used to demonstrate the implementations of the proposed multi-year crop insurance. The proposed multi-year plan would benefit farmers by offering insurance guarantees across years for significantly lower costs. PMID:26695074

The company they keep: drinking group attitudes and male bar aggression.

The purpose of this study was to assess (a) similarities in self-reported bar-aggression-related attitudes and behaviors among members of young male groups recruited on their way to bars and (b) group-level variables associated with individual members' self-reported likelihood of perpetrating physical bar aggression in the past year, controlling for individual attitudes. Young, male, natural drinking groups recruited on their way to a bar district Thursday, Friday, and Saturday nights (n = 167, 53 groups) completed an online survey that measured whether they had perpetrated physical aggression at a bar in the past year and constructs associated with bar aggression, including attitudes toward male bar aggression and frequency of heavy episodic drinking in the past year. Intraclass correlations and chi-square tests demonstrated significant within-group similarity on bar-aggression-related attitudes and behaviors (ps < .01). Hierarchical linear modeling revealed that group attitudes toward bar aggression were significantly associated with individuals' likelihood of perpetrating physical bar aggression, controlling for individual attitudes (p < .01); however, the link between group heavy episodic drinking and self-reported bar aggression was nonsignificant in the full model. This study suggests that the most important group influence on young men's bar aggression is the attitudes of other group members. These attitudes were associated with group members' likelihood of engaging in bar aggression over and above individuals' own attitudes. A better understanding of how group attitudes and behavior affect the behavior of individual group members is needed to inform aggression-prevention programming.

Psychological Aggression, Physical Aggression, and Injury in Nonpartner Relationships Among Men and Women in Treatment for Substance-Use Disorders*

Objective: This study focused on the prevalence and predictors of psychological aggression, physical aggression, and injury rates in nonintimate partner relationships in a substance-use disorder treatment sample. Method: The sample included 489 (76% men, 24% women) participants who completed screening measures for inclusion in a randomized control trial for an aggression-prevention treatment. Primary outcome measures included rates of past-year psychological aggression, physical aggression, and injury (both from the participant to nonpartners and from nonpartners to the participant). Potential predictors included individual factors (e.g., age, gender), developmental factors (e.g., family history of drug use, childhood physical abuse), and recent factors (e.g., depression, cocaine use). Results: Rates of participant-tononpartner psychological aggression (83%), physical aggression (61%), and injury (47%) were high, as were rates of nonpartner-to-participant aggression. Bivariate analyses revealed significant relationships between the aggression outcomes and most of the individual, developmental, and recent factors. However, multivariate analyses (zero-inflated Poisson regression) revealed that age, treatment status, current symptoms of depression, heavy periods of drinking, and cocaine use were related most frequently to the occurrence of aggression to and from nonpartners. Conclusions: Nonpartner aggression may be as common within a substance-use disorder sample as partner aggression, and it is associated with heavy drinking episodes, cocaine use, and depressive symptoms. The findings highlight the need for the development of effective violence interventions addressing violence in nonpartner relationship types. PMID:18925348

This study aims to explore the frequency of aggressive behaviors among a nationally representative sample of Iranian children and adolescents. This nationwide study was performed on a multi-stage sample of 6-18 years students, living in 30 provinces in Iran. Students were asked to confidentially report the frequency of aggressive behaviors including physical fighting, bullying and being bullied in the previous 12 months, using the questionnaire of the World Health Organization Global School Health Survey. In this cross-sectional study, 13,486 students completed the study (90.6% participation rate); they consisted of 49.2% girls and 75.6% urban residents. The mean age of participants was 12.47 years (95% confidence interval: 12.29, 12.65). In total, physical fight was more prevalent among boys than girls (48% vs. 31%, P < 0.001). Higher rates of involvement in two other behaviors namely being bullied and bulling to other classmates had a higher frequency among boys compared to girls (29% vs. 25%, P < 0.001 for being bullied) and (20% vs. 14%, P < 0.001 for bulling to others). Physical fighting was more prevalent among rural residents (40% vs. 39%, respectively, P = 0.61), while being bullied was more common among urban students (27% vs. 26%, respectively, P = 0.69). Although in this study the frequency of aggressive behaviors was lower than many other populations, still these findings emphasize on the importance of designing preventive interventions that target the students, especially in early adolescence, and to increase their awareness toward aggressive behaviors. Implications for future research and aggression prevention programming are recommended.

Background Frameworks for studying the ecology of human behavior suggest that multiple levels of the environment influence behavior and that these levels interact. Applied to studies of weapons aggression, this suggests proximal risk factor (e.g., substance use) effects may differ across neighborhoods. Objectives To estimate how the association between weapons aggression and substance use varies as a function of several community-level variables. Methods Individual-level measures (demographics, behavioral measures) were obtained from a survey of youth aged 14–24 years old seeking care at a Level-1 ED in Flint, Michigan. Community-level variables were obtained from public sources. Logistic generalized additive models were used to test whether community-level variables (crime rates, alcohol outlets, demographics) modify the link between individual-level substance use variables and the primary outcome measure: self-reported past 6-month weapon (firearm/knife) related aggression. Results The effect of marijuana misuse on weapons aggression varied significantly as a function of five community-level variables: racial composition, vacant housing rates, female headed household rates, density of package alcohol outlets, and nearby drug crime rates. The effect of high-risk alcohol use did not depend on any of the eight community variables tested. Conclusions The relationship between marijuana misuse and weapons aggression differed across neighborhoods with generally less association in more disadvantaged neighborhoods, while high-risk alcohol use showed a consistently high association with weapons aggression that did not vary across neighborhoods. The results aid in understanding the contributions of alcohol and marijuana use to the etiology of weapon-related aggression among urban youth, but further study in the general population is required.

2014-01-01

The current study explored longitudinal associations between interparental aggression, the development of child attention skills, and early childhood behavior problems in a diverse sample of 636 families living in predominately low-income, nonmetropolitan communities. The results of latent-variable, cross-lagged longitudinal models revealed that maternal-reported interparental aggression in infancy predicted reduced observed attention skills in toddlerhood; no association was observed, however, between attention in infancy and interparental aggression during the toddler years. Further, reduced toddler attention and high interparental aggression were both associated with increased risk for attention-deficit/hyperactivity disorder symptoms and conduct problems at 3 years of age. Processes largely operated in similar ways regardless of child gender or low-income status, although a few differences were observed. Overall, the results suggest that interparental aggression undermines attention development, putting children’s early behavioral adjustment at risk. PMID:23786696

Multi-unit housing environments remain significant sources of secondhand smoke (SHS) exposure, especially for vulnerable populations in subsidized housing. In Philadelphia, the largest US housing authority to implement smoke-free policies, we measured baseline resident smoking-related behaviors and attitudes, and longitudinal exposures to airborne nicotine, during policy development and implementation. In 4 communities, we collected data in 2013, 2014, and 2016, before and after introduction of comprehensive smoke-free policies, interviewing persons in 172 households, and monitoring air-borne nicotine in non-smoking homes and public areas. Average nicotine level differences across years were estimated with multi-level models. Fifty-six percent of respondents smoked. Only 37% of households were smoke-free, with another 41% restricting smoking by area or time of day. The number of locations with detectable nicotine did not differ before and after policy implementation, with approximately 20% of non-smoking homes and 70%-80% of public areas having detectable nicotine. However, public area nicotine levels were lower in 2016, after policy implementation, than in 2013 and 2014 (-0.19 μg/m 3 , p = .03). Findings suggest that initial policy implementation was associated with reduced SHS exposure in Philadelphia. As HUD strengthens smoke-free policies, SHS monitoring can be useful to educate stakeholders and build support for policy enforcement.

2006-01-01

The concept of aggression is important to nursing because further knowledge of aggression can help generate a better theoretical model to drive more effective intervention and prevention approaches. This paper outlines a conceptual analysis of aggression. First, the different forms of aggression are reviewed, including the clinical classification and the stimulus-based classification. Then the manifestations and measurement of aggression are described. Finally, the causes and consequences of aggression are outlined. It is argued that a better understanding of aggression and the causal factors underlying it are essential for learning how to prevent negative aggression in the future. PMID:15371137

Sense of control and adolescents' aggression: The role of aggressive cues.

PubMed

Guo, Xucheng; Egan, Vincent; Zhang, Jianxin

2016-12-01

The misperception of aggressive cues is considered a risk factor for inducing adolescent aggression. Poor coping with life stress is also considered a major influence on aggression. The current study examined the relationship between subjective sense of control and adolescent aggression, considering influences upon the perception of these aggressive cues. In Study 1, 60 participants took part in a 2 (sense of control: high sense of control vs. low sense of control) × 2 (aggressive cue: aggressive vs. neutral) between-subjects contextual experiment. The result found that a lower sense of control led to an increase in adolescents' aggression; only in the low-sense-of-control condition did exposure to aggressive cues boost aggression. In Study 2, the catalytic effect of aggressive cues was further explored by an experiment in which 40 adolescents were randomly assigned to a low- or high-sense-of-control condition to test the importance of aggressive cues. The results suggest that adolescents in the low-sense-of-control condition show a higher salience for aggressive cues. © 2016 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

A multi-gate screening process identified 891 children with aggressive-disruptive behavior problems at school entry. Fast Track provided a multi-component preventive intervention in the context of a randomized-controlled design. In addition to psychosocial support and skill training for parents and children, the intervention included intensive reading tutoring in first grade, behavioral management consultation with teachers, and the provision of homework support (as needed) through tenth grade. This study examined the impact of the intervention, as well as the impact of the child's initial aggressive-disruptive behaviors and associated school readiness skills (cognitive ability, reading readiness, attention problems) on academic progress and educational placements during elementary school (Grades 1-4) and during the secondary school years (Grades 7-10), as well as high school graduation. Child behavior problems and skills at school entry predicted school difficulties (low grades, grade retention, placement in a self-contained classroom, behavior disorder classification, and failure to graduate). Disappointingly, intervention did not significantly improve these long-term school outcomes. © 2013 Wiley Periodicals, Inc.

The primary research objective was to explore the relationship between trajectories of maternal verbal aggression (VA) experienced by low-income, community middle school students across a three-year period and outcomes that have been found to be related to VA in previous work, including a negative view of self and social problems. Longitudinal data were collected from 421 youth (51.8% male) attending two middle schools over 3 years using a multiple-informant survey design. K-means cluster analysis was used to identify trajectories of VA using youth ratings of the Conflict Tactics Scale: Parent-Child (Straus, Hamby, Finkelhor, Moore, & Runyan, 1998). Dependent variables were self-reported depression, self-esteem, delinquency, and peer victimization as well as peer-rated aggression and sensitive-isolated reputation. Four trajectory groups of VA were identified: Low Stable, Increasing, Decreasing, and High Stable. The 3-year average occurrence of VA was: 1.31, 9.18, 10.24, and 31.14 instances, respectively. Gender-specific MANOVAs revealed dramatic differences between the High Stable and Low Stable groups. High Stable boys reported significantly more depressive symptoms, delinquency, peer overt and relational victimization, and were less likely to have a sensitive/isolated reputation than Low Stable boys. High Stable girls reported significantly more depressive symptoms, low self-esteem, delinquency, peer overt and relational victimization and were rated by peers as having more aggressive/disruptive and relationally aggressive reputations than Low Stable girls. Girls in the High Stable group were more likely than other youth to report levels of depressive symptoms and delinquency >1 SD above the mean, while boys in the High Stable group were more likely to report levels of delinquency >1 SD above the mean. The Increasing and Decreasing groups also demonstrated significantly poorer functioning than the Low Stable group on most outcomes. Growth curve analysis revealed

Alcohol and cannabis use have been implicated in aggression. Alcohol consumption is known to facilitate aggression, whereas a causal link between cannabis and aggression has not been clearly demonstrated. This study investigated the acute effects of alcohol and cannabis on subjective aggression in alcohol and cannabis users, respectively, following aggression exposure. Drug-free controls served as a reference. It was hypothesized that aggression exposure would increase subjective aggression in alcohol users during alcohol intoxication, whereas it was expected to decrease subjective aggression in cannabis users during cannabis intoxication. Heavy alcohol (n = 20) and regular cannabis users (n = 21), and controls (n = 20) were included in a mixed factorial study. Alcohol and cannabis users received single doses of alcohol and placebo or cannabis and placebo, respectively. Subjective aggression was assessed before and after aggression exposure consisting of administrations of the point-subtraction aggression paradigm (PSAP) and the single category implicit association test (SC-IAT). Testosterone and cortisol levels in response to alcohol/cannabis treatment and aggression exposure were recorded as secondary outcome measures. Subjective aggression significantly increased following aggression exposure in all groups while being sober. Alcohol intoxication increased subjective aggression whereas cannabis decreased the subjective aggression following aggression exposure. Aggressive responses during the PSAP increased following alcohol and decreased following cannabis relative to placebo. Changes in aggressive feeling or response were not correlated to the neuroendocrine response to treatments. It is concluded that alcohol facilitates feelings of aggression whereas cannabis diminishes aggressive feelings in heavy alcohol and regular cannabis users, respectively.

Male CB1KO mice exhibit stronger aggressive responses than wild-type mice. This study was designed to examine the role of cannabinoid CB2r in social and aggressive behavior. The social interaction test and resident-intruder paradigm were performed in mice lacking CB2r (CB2KO) and in wild-type (WT) littermates. The effects of the CB2r selective agonist JWH133 (1 and 2 mg/kg) on aggression were also evaluated in Oncins France 1 (OF1) mice. Gene expression analyses of monoamine oxidase-A (MAO-A), catechol-o-methyltransferase (COMT), 5-hydroxytryptamine transporter (5-HTT), and 5-HT1B receptor (5HT1Br) in the dorsal raphe nuclei (DR) and the amygdala (AMY) were carried out using real-time PCR. Group-housed CB2KO mice exhibited higher levels of aggression in the social interaction test and displayed more aggression than resident WT mice. Isolation increased aggressive behavior in WT mice but did not affect CB2KO animals; however, the latter mice exhibited higher levels of social interaction with their WT counterparts. MAO-A and 5-HTT gene expression was significantly higher in grouped CB2KO mice. The expression of 5HT1Br, COMT, and MAO-A in the AMY was more pronounced in CB2KO mice than in WT counterparts. Acute administration of the CB2 agonist JWH133 significantly reduced the level of aggression in aggressive isolated OF1 mice, an effect that decreased after pretreatment with the CB2 receptor antagonist AM630. Our results suggest that CB2r is implicated in social interaction and aggressive behavior and deserves further consideration as a potential new target for the management of aggression.

Evaluations of associations between sleep at night and aggressive behaviour in Psychiatric Intensive Care Units (PICU) are lacking. The aims were to explore if sleep duration or night-to-night variations in sleep duration correlated with aggressive behaviour and aggressive incidents the next day and through the whole admission. Fifty consecutive patients admitted to a PICU were included (521 nights) and the nurses registered the time patients were sleeping, aggressive behaviour with The Brøset Violence Checklist (BVC) and aggressive incidents with The Staff Observation Aggression Scale-Revised (SOAS-R). At admission, short sleep duration the first night correlated with aggressive behaviour the next day and admissions with violent incidents had a median of 4.0 h difference in sleep from night one to night two compared to 2.1 h for the rest of the admissions. During the stay, large absolute difference in sleep duration between two nights correlated with aggressive behaviour the next day and short sleep duration was associated with violent incidents. Short sleep duration and night-to-night variations in sleep duration are both associated with increased risk for aggression in PICUs. This observation might help to predict and prevent aggressive incidents. Copyright © 2018 Elsevier B.V. All rights reserved.

Neurobiological factors in aggressive behavior.

PubMed

Garza-Treviño, E S

1994-07-01

The author's aim was to review literature in the neurosciences and psychiatric clinical research reports about biological factors in aggression and the pathophysiological mechanisms that accompany aggression in neuropsychiatric syndromes. Studies were located through computer searches of relevant experimental reports and review articles mainly from the last 25 years. Several studies using neuroimaging and neurophysiological and neuropathological research techniques have identified lesions in the limbic structures, temporal lobes, and frontal lobes of the brain in abnormally aggressive individuals. Several reports have associated deficiency or dysregulation of serotonin with homicidal, suicidal, and impulsive behavior. However, few studies have focused on polypeptides or second messenger systems, although abnormalities in these systems have been reported in patients with neuropsychiatric syndromes who have shown aggressive behavior. Even fewer studies focus on the correlation of brain structures and metabolic markers. The understanding of aggressive behavior in psychiatric patients is fragmented. Some explanations are speculative and extrapolated to clinical psychiatric syndromes from experimental data on the neurophysiology of cats, rats, and other mammals. Identification of biochemical markers that can be used in predicting patients' response to pharmacological interventions may be the next step in developing more rational treatment of violent patients.

Is aggressive treatment of traumatic brain injury cost-effective?

2012-05-01

The object of this study was to determine whether aggressive treatment of severe traumatic brain injury (TBI), including invasive intracranial monitoring and decompressive craniectomy, is cost-effective. A decision-analytical model was created to compare costs, outcomes, and cost-effectiveness of 3 strategies for treating a patient with severe TBI. The aggressive-care approach is compared with "routine care," in which Brain Trauma Foundation guidelines are not followed. A "comfort care" category, in which a single day in the ICU is followed by routine floor care, is included for comparison only. Probabilities of each treatment resulting in various Glasgow Outcome Scale (GOS) scores were obtained from the literature. The GOS scores were converted to quality-adjusted life years (QALYs), based on expected longevity and calculated quality of life associated with each GOS category. Estimated direct (acute and long-term medical care) and indirect (loss of productivity) costs were calculated from the perspective of society. Sensitivity analyses employed a 2D Monte Carlo simulation of 1000 trials, each with 1000 patients. The model was also used to estimate these values for patients 40, 60, and 80 years of age. For the average 20-year-old, aggressive care yields 11.7 (± 1.6 [SD]) QALYs, compared with routine care (10.0 ± 1.5 QALYs). This difference is highly significant (p < 0.0001). Although the differences in effectiveness between the 2 strategies diminish with advancing age, aggressive care remains significantly better at all ages. When all costs are considered, aggressive care is also significantly less costly than routine care ($1,264,000 ± $118,000 vs $1,361,000 ± $107,000) for the average 20-year-old. Aggressive care remains significantly less costly until age 80, at which age it costs more than routine care. However, even in the 80-year-old, aggressive care is likely the more cost-effective approach. Comfort care is associated with poorer outcomes at all ages

The members of the Swain family- Dr. Charles "Bill" Swain, wife Elaine, daughter Carol, 17, son "Chuck", 12, and dog Susie have an interesting assignment. They are active participants in an important NASA research program involving the application of space-age technology to home construction. b' Transplanted Floridians, the Swains now reside in NASA's Tech House, loatedat Langley Research Center, Hampton, Virginia. Their job is to use and help evaluate the variety of advanced technology systems in Tech House. A contemporary three-bedroom home, Tech House incorporates NASA technology, the latest commercial building techniques and other innovations, all designed to reduce energy and water consumption and to provide new levels of comfort, convenience, security and fire safety. Tech House equipment performed well in initial tests, but a house is not a home until it has people. That's where the Swains come in. NASA wants to see how the various systems work under actual living conditions, to confirm the effectiveness of the innovations or to determine necessary modifications for improvement. The Swains are occupying the house for a year, during which NASA engineers are computer monitoring the equipment and assembling a record of day-to-day performance. . Tech House is a laboratory rather than a mass production prototype, but its many benefits may influence home design and construction. In a period of sharply rising utility costs, widespread adoption of Tech House features could provide large-scale savings to homeowners and potentially enormous national benefit in resources conservation. Most innovations are aerospace spinoffs: Some of the equipment is now commercially available; other systems are expected to be in production within a few years. Around 1980, a Tech House-type of home could be built for $45-50,000 (1 976 dollars). It is estimated that the homeowner would save well over $20,000 (again 1976 dollars) in utility costs over the average mortgage span of 20 years.

This study investigated whether young people's substance use and aggressive behaviors are related to their listening to music containing messages of substance use and violence. Using self-administered questionnaires, data were collected from a sample of community-college students, ages 15-25 years (N=1056; 57% female). A structural equation model (maximum likelihood method) was used to simultaneously assess the associations between listening to various genres of music and students' alcohol use, illicit-drug use, and aggressive behaviors. Respondents' age, gender, race/ethnicity, and level of sensation seeking were included in the analyses as control variables. Listening to rap music was significantly and positively associated with alcohol use, problematic alcohol use, illicit-drug use, and aggressive behaviors when all other variables were controlled. In addition, alcohol and illicit-drug use were positively associated with listening to musical genres of techno and reggae. Control variables (e.g., sensation seeking, age, gender and race/ethnicity) were significantly related to substance use and aggressive behaviors. The findings suggest that young people's substance use and aggressive behaviors may be related to their frequent exposure to music containing references to substance use and violence. Music listening preference, conversely, may reflect some personal predispositions or lifestyle preferences. There is also the possibility that substance use, aggression, and music preference are independent constructs that share common "third factors".

Light-sheet fluorescence microscopy (LSFM) uses an additional laser-sheet to illuminate selective planes of the sample, thereby enabling three-dimensional imaging at high spatial-temporal resolution. These advantages make LSFM a promising tool for high-quality brain visualization. However, even by the use of LSFM, the spatial resolution remains insufficient to resolve the neural structures across a mesoscale whole mouse brain in three dimensions. At the same time, the thick-tissue scattering prevents a clear observation from the deep of brain. Here we use multi-view LSFM strategy to solve this challenge, surpassing the resolution limit of standard light-sheet microscope under a large field-of-view (FOV). As demonstrated by the imaging of optically-cleared mouse brain labelled with thy1-GFP, we achieve a brain-wide, isotropic cellular resolution of 3μm. Besides the resolution enhancement, multi-view braining imaging can also recover complete signals from deep tissue scattering and attenuation. The identification of long distance neural projections across encephalic regions can be identified and annotated as a result.

The cryptomnesic origins of Jung's dream of the multi-storeyed house.

PubMed

Myers, Steve

2009-09-01

Jung first recounted his dream of the multi-storeyed house in the 1925 seminars to illustrate the concept of the collective unconscious and explain the influence of phylogeny on his split with Freud. However, his telling the story of the dream belies a cryptomnesic influence of the early writings of psychoanalysis because Josef Breuer used a similar image to illustrate the structure of the psyche which Edouard Claparède associated with a phylogenetic inheritance. When telling the story of the dream, Jung misrepresented Freud's position, creating the impression of there being a bigger difference between their theories than was actually the case, and giving the dream a fictional significance for the breakdown of their relationship. In fact, Jung followed Freud into the fields of mythology and phylogenetics, and their split was due primarily to their different attitudes towards sexuality rather than phylogeny. The dream image has therefore led to a misunderstanding of Freudian theory when viewed from within a Jungian perspective. Freud believed there was a phylogenetic layer in the psyche, though he held a different view to Jung on its nature and importance.

Signaling aggression.

PubMed

van Staaden, Moira J; Searcy, William A; Hanlon, Roger T

2011-01-01

From psychological and sociological standpoints, aggression is regarded as intentional behavior aimed at inflicting pain and manifested by hostility and attacking behaviors. In contrast, biologists define aggression as behavior associated with attack or escalation toward attack, omitting any stipulation about intentions and goals. Certain animal signals are strongly associated with escalation toward attack and have the same function as physical attack in intimidating opponents and winning contests, and ethologists therefore consider them an integral part of aggressive behavior. Aggressive signals have been molded by evolution to make them ever more effective in mediating interactions between the contestants. Early theoretical analyses of aggressive signaling suggested that signals could never be honest about fighting ability or aggressive intentions because weak individuals would exaggerate such signals whenever they were effective in influencing the behavior of opponents. More recent game theory models, however, demonstrate that given the right costs and constraints, aggressive signals are both reliable about strength and intentions and effective in influencing contest outcomes. Here, we review the role of signaling in lieu of physical violence, considering threat displays from an ethological perspective as an adaptive outcome of evolutionary selection pressures. Fighting prowess is conveyed by performance signals whose production is constrained by physical ability and thus limited to just some individuals, whereas aggressive intent is encoded in strategic signals that all signalers are able to produce. We illustrate recent advances in the study of aggressive signaling with case studies of charismatic taxa that employ a range of sensory modalities, viz. visual and chemical signaling in cephalopod behavior, and indicators of aggressive intent in the territorial calls of songbirds.

Rungee, J. P., II; Bales, R. C.

2017-12-01

Analysis of measured evapotranspiration shows multi-year regolith water storage can support evapotranspiration for years into a multi-year dry period. Measurements at 25 flux-tower sites in the semi-arid western United States, distributed across five primary land-cover types, show both resilience and vulnerability to multi-year dry periods. Average evapotranspiration ranged from about 700+200 mm per water year (October-September) in evergreen needleleaf forests to 350+150 mm per water year in grasslands and open shrublands. On average, in California's Mediterranean climate almost half of the water-year evapotranspiration is supported by seasonal and/or multi-year regolith water storage, compared to a characteristic 20 to 30 percent value of energy-limited and inland sites. Below 35oN latitude, water-year evapotranspiration exceeded estimated precipitation in over half of the years on record. For non-energy-limited sites, water-year evapotranspiration increased with precipitation up to a maximum water-year evapotranspiration value of about 900, 750, 600, 425 and 300 mm per water year for evergreen needleleaf forests, mixed forests, woody savannas, grasslands and open shrublands, respectively. There were 15 multi-year dry periods on record that exhibited either an attenuation in evapotranspiration, defined as an annual value below 80% of the wet-year average, or withdrawal from multi-year storage. A multi-year dry period was defined as three or more consecutive water years in which all water-year precipitation values and the mean period value were in the lower 50 and 35 percent of the historical record, respectively. For sites exhibiting evapotranspiration attenuation, resistance to multi-year dry periods ranged from 9 to 49 months, drafting as much as 444 mm of regolith storage. At some mountain sites regolith storage provided up to 678 mm, almost the equivalent of the average water-year evapotranspiration for these sites, over the extent of the multi-year dry

This study examined the direct and indirect associations between maternal cocaine use during pregnancy and mother-toddler aggression in an interactive context at 2 years of child age. We hypothesized that in addition to direct effects of cocaine exposure on maternal and child aggression, the association between maternal cocaine use and mother-toddler aggression may be indirect via higher maternal psychiatric symptoms, negative affect, or poor infant autonomic regulation at 13 months. Participants consisted of 220 (119 cocaine exposed, 101 non-cocaine exposed) mother-toddler dyads participating in an ongoing longitudinal study of prenatal cocaine exposure. Results indicated that mothers who used cocaine during pregnancy displayed higher levels of aggression toward their toddlers compared to mothers in the control group. Results from model testing indicated significant indirect associations between maternal cocaine use and maternal aggression via higher maternal negative affect as well as lower infant autonomic regulation at 13 months. Although there were no direct associations between cocaine exposure and toddler aggression, there was a significant indirect effect via lower infant autonomic regulation at 13 months. Results highlight the importance of including maternal aggression in predictive models of prenatal cocaine exposure examining child aggression. Results also emphasize the important role of infant regulation as a mechanism partially explaining associations between cocaine exposure and mother-toddler aggression. PMID:21396441

This study compared the development until 9 wk of age of piglets raised in either a multi-litter (ML) system or a conventional single-litter (SL) system. The ML system consisted of a multi-suckling system with 5 sows and their litters before weaning, followed by housing in a pen with enrichment in a group of 40 piglets after weaning. In the SL system, piglets were housed with a crated sow before weaning, followed by postweaning housing in groups of 10 littermates in a standard pen. Fifty litters were used in 5 batches and piglets were weaned at 4 wk of age. Preweaning mortality was higher in the ML system than in the SL system (3.22 ± 0.42 vs. 1.52 ± 0.25 piglets per litter, < 0.01), mainly due to crushing before grouping of litters. Litter size at grouping did not differ between systems. ML piglets showed more feed-directed behavior at 2 wk of age (6.80 ± 0.96 vs. 2.35 ± 0.59, < 0.01), suggesting an earlier start of feed exploration, possibly due to social learning from the floor-fed sows and other piglets. Moreover, before weaning, ML piglets showed less damaging oral manipulation (e.g., tail biting) than SL piglets (1.4 ± 0.2 vs. 3.6 ± 0.3 freq/h, < 0.001), which was likely related to the more enriched environment in the ML system. After weaning, ML piglets ate 81% more feed between d 1 and 2 (0.29 ± 0.02 vs. 0.16 ± 0.03 kg/piglet, < 0.01) and had an 82% higher weight gain until d 5 than SL piglets (1.35 ± 0.21 vs. 0.75 ± 0.17 kg, < 0.05) despite a similar weaning weight (ML: 8.4 ± 0.2 kg, SL: 8.3 ± 0.2 kg). Within the first 2 wk after weaning, ML piglets had a lower fecal consistency score (0.27 ± 0.03 vs. 0.39 ± 0.03, < 0.05), indicating a lower occurrence of diarrhea compared with SL piglets. Over the entire 5-wk postweaning phase, ML piglets had a 24% higher weight gain ( < 0.05) and showed more play behavior (4.0 ± 0.3 vs. 2.8 ± 0.3 freq/h, < 0.05) and less damaging oral manipulation (1.8 ± 0.3 vs. 3.5 ± 0.4 freq/h, < 0.01) than SL piglets

Background Allergic rhinitis is the most common allergic disorder. Although the management of the disease is successful in many patients, based on guidelines, some of them remain with symptoms uncontrolled with pharmacotherapy. Presently, there is no substantiated information on the control of allergic rhinitis in patients who underwent sublingual immunotherapy. Objective The purpose of this prospective follow-up study was to assess the control of allergic rhinitis in adults after a three-year course of house dust mite sublingual immunotherapy. Methods This prospective real-life study was designed to include adults with moderate to severe allergic rhinitis sensitized to house dust mite who underwent a three-year course of sublingual immunotherapy. Control of symptoms was assessed by Rhinitis Control Assessment Test (RCAT) after three years of house dust mite sublingual immunotherapy. Additionally, patients assessed their symptoms by utilizing a visual analog scale. Results A total number of 86 consecutively enrolled patients (46 (53.49%) men; mean age 26.10 years (SD = 5.85)) with moderate to severe allergic rhinitis and clinically relevant sensitization to house dust mite were evaluated. When assessed by RCAT on the third year, 74 (86.05%) had well-controlled symptoms and 20 (27.03%) of them were completely controlled. A significant reduction in visual analog scale scores-from 7.52 cm at baseline to 2.31 cm-was established ( P < 0.0001). There was a strong negative correlation between RCAT scores and visual analog scale (r = -0.65; P < 0.01). Conclusion This study provided evidence that a three-year course of house dust mite sublingual immunotherapy appears effective in controlling the symptoms of allergic rhinitis.

The duplication of genes can occur through various mechanisms and is thought to make a major contribution to the evolutionary diversification of organisms. There is increasing evidence for a large-scale duplication of genes in some chelicerate lineages including two rounds of whole genome duplication (WGD) in horseshoe crabs. To investigate this further, we sequenced and analyzed the genome of the common house spider Parasteatoda tepidariorum. We found pervasive duplication of both coding and non-coding genes in this spider, including two clusters of Hox genes. Analysis of synteny conservation across the P. tepidariorum genome suggests that there has been an ancient WGD in spiders. Comparison with the genomes of other chelicerates, including that of the newly sequenced bark scorpion Centruroides sculpturatus, suggests that this event occurred in the common ancestor of spiders and scorpions, and is probably independent of the WGDs in horseshoe crabs. Furthermore, characterization of the sequence and expression of the Hox paralogs in P. tepidariorum suggests that many have been subject to neo-functionalization and/or sub-functionalization since their duplication. Our results reveal that spiders and scorpions are likely the descendants of a polyploid ancestor that lived more than 450 MYA. Given the extensive morphological diversity and ecological adaptations found among these animals, rivaling those of vertebrates, our study of the ancient WGD event in Arachnopulmonata provides a new comparative platform to explore common and divergent evolutionary outcomes of polyploidization events across eukaryotes.

The mismatch between conventional house price modeling and regulated markets: insights from The Netherlands.

PubMed

Tu, Qi; de Haan, Jan; Boelhouwer, Peter

2017-01-01

House price modeling has been frequently used to investigate the dynamics of housing markets, especially competitive markets; yet less attention has been given to markets that have experienced considerable interventions. The aim of this study is to demonstrate a mismatch between conventional house price models and the case of the Netherlands and to provide reasons of such mismatch. We first describe and classify the conventional house price models into asset-pricing house price model, stock-flow model, multi-period utility model, and repayment model. These models are subsequently applied to the Netherlands, where considerable government interventions took place. As expected, the empirical results are unsatisfactory to explain the Dutch house price development. The degree of mismatch of the repayment model and the multi-period utility model, however, seems to be fairly limited.

Sublingual immunotherapy in patients with allergic rhinitis sensitised to house dust mites is safe, but its efficacy is controversial and sublingual immunotherapy with Blomia tropicalis has not yet been studied. This study sought to evaluate the efficacy of sublingual immunotherapy with house dust mite extract in children and adults with house dust mite allergic rhinitis over a period of two years. A prospective observational study was conducted of children and adults diagnosed with house dust mite allergic rhinitis who were treated with sublingual immunotherapy from 2008 to 2012. Total Nasal Symptom Scores, Mini Rhinoconjunctivitis Quality of Life scores and medication usage scores were assessed prospectively. Thirty-nine patients, comprising 24 children and 15 adults, were studied. Total Nasal Symptom Scores and Mini Rhinoconjunctivitis Quality of Life scores dropped significantly at three months into therapy, and continued to improve. Medication usage scores improved at one year into immunotherapy. Sublingual immunotherapy with house dust mite extracts, including B tropicalis, is efficacious as a treatment for patients with house dust mite allergic rhinitis.

Background: This study aims to explore the frequency of aggressive behaviors among a nationally representative sample of Iranian children and adolescents. Methods: This nationwide study was performed on a multi-stage sample of 6–18 years students, living in 30 provinces in Iran. Students were asked to confidentially report the frequency of aggressive behaviors including physical fighting, bullying and being bullied in the previous 12 months, using the questionnaire of the World Health Organization Global School Health Survey. Results: In this cross-sectional study, 13,486 students completed the study (90.6% participation rate); they consisted of 49.2% girls and 75.6% urban residents. The mean age of participants was 12.47 years (95% confidence interval: 12.29, 12.65). In total, physical fight was more prevalent among boys than girls (48% vs. 31%, P < 0.001). Higher rates of involvement in two other behaviors namely being bullied and bulling to other classmates had a higher frequency among boys compared to girls (29% vs. 25%, P < 0.001 for being bullied) and (20% vs. 14%, P < 0.001 for bulling to others). Physical fighting was more prevalent among rural residents (40% vs. 39%, respectively, P = 0.61), while being bullied was more common among urban students (27% vs. 26%, respectively, P = 0.69). Conclusions: Although in this study the frequency of aggressive behaviors was lower than many other populations, still these findings emphasize on the importance of designing preventive interventions that target the students, especially in early adolescence, and to increase their awareness toward aggressive behaviors. Implications for future research and aggression prevention programming are recommended. PMID:25789141

Wright, Michelle F; Li, Yan

2013-01-01

This longitudinal study examined normative beliefs about aggression (e.g., face-to-face, cyber) in relation to the engagement in cyber aggression 6 months later among 126 (69 women) young adults. Participants completed electronically administered measures assessing their normative beliefs, face-to-face and cyber aggression at Time 1, and cyber aggression 6 months later (Time 2). We found that men reported more cyber relational and verbal aggression when compared to women. After controlling for each other, Time 1 face-to-face relational aggression was positively related to Time 2 cyber relational aggression, whereas Time 1 face-to-face verbal aggression was positively related to Time 2 cyber verbal aggression. Normative beliefs regarding cyber aggression was positively related to both forms of cyber aggression 6 months later, after controlling for normative beliefs about face-to-face aggression. Furthermore, a significant two-way interaction between Time 1 cyber relational aggression and normative beliefs about cyber relational aggression was found. Follow-up analysis showed that Time 1 cyber relational aggression was more strongly related to Time 2 cyber relational aggression when young adults held higher normative beliefs about cyber relational aggression. A similar two-way interaction was found for cyber verbal aggression such that the association between Time 1 and Time 2 cyber verbal aggression was stronger at higher levels of normative beliefs about cyber verbal aggression. Results are discussed in terms of the social cognitive and behavioral mechanisms associated with the engagement of cyber aggression. © 2013 Wiley Periodicals, Inc.

Some human behaviors, including aggression and activity level, differ on average for males and females. Here we report findings from two studies investigating possible relations between prenatal androgen and children's aggression and activity level. For study 1, aggression and activity level scores for 43 girls and 38 boys, aged 4 to 11years, with congenital adrenal hyperplasia (CAH, a genetic condition causing increased adrenal androgen production beginning prenatally) were compared to those of similarly-aged, unaffected relatives (41 girls, 31 boys). Girls with CAH scored higher on aggression than unaffected girls, d=0.69, and unaffected boys scored higher on activity level than unaffected girls, d=0.50. No other group differences were significant. For study 2, the relationship of amniotic fluid testosterone to aggression and activity level was investigated in typically-developing children (48 girls, 44 boys), aged 3 to 5years. Boys scored higher than girls on aggression, d=0.41, and activity level, d=0.50. However, amniotic fluid testosterone was not a significant predictor of aggression or activity level for either sex. The results of the two studies provide some support for an influence of prenatal androgen exposure on children's aggressive behavior, but not activity level. The within-sex variation in amniotic fluid testosterone may not be sufficient to allow reliable assessment of relations to aggression or activity level. Copyright © 2017 Elsevier Inc.

In unaneasthetized and unrestrained cats, muscarine and carbachol were injected into the cerebral ventricles. The kind of aggressive behaviour depended on the cholinomimetic drug and was classified as fear and an irritable kind of aggression. Muscarine induced the fear kind of aggression. The aggressive behaviour was usually preceded by attempts to escape and the attack was relevant to the situation. For the attack the presence of some threatening agent was needed. The aggression was accompanied by intense motor but less autonomic activation. On the other hand, carbachol induced an irritable kind of aggression and had the following characteristics: for the attack the presence of some threatening agent was not needed; the attack was not relevant to the situation; the aggression was not preceded by attempts to escape; and the aggressive behaviour was accompanied by intense motor and autonomic activation. It is concluded that cholinoceptive mechanisms are involved in the control of aggressive behaviour.

Implicit cognitive aggression among young male prisoners: Association with dispositional and current aggression.

PubMed

Ireland, Jane L; Adams, Christine

2015-01-01

The current study explores associations between implicit and explicit aggression in young adult male prisoners, seeking to apply the Reflection-Impulsive Model and indicate parity with elements of the General Aggression Model and social cognition. Implicit cognitive aggressive processing is not an area that has been examined among prisoners. Two hundred and sixty two prisoners completed an implicit cognitive aggression measure (Puzzle Test) and explicit aggression measures, covering current behaviour (DIPC-R) and aggression disposition (AQ). It was predicted that dispositional aggression would be predicted by implicit cognitive aggression, and that implicit cognitive aggression would predict current engagement in aggressive behaviour. It was also predicted that more impulsive implicit cognitive processing would associate with aggressive behaviour whereas cognitively effortful implicit cognitive processing would not. Implicit aggressive cognitive processing was associated with increased dispositional aggression but not current reports of aggressive behaviour. Impulsive implicit cognitive processing of an aggressive nature predicted increased dispositional aggression whereas more cognitively effortful implicit cognitive aggression did not. The article concludes by outlining the importance of accounting for implicit cognitive processing among prisoners and the need to separate such processing into facets (i.e. impulsive vs. cognitively effortful). Implications for future research and practice in this novel area of study are indicated. Copyright © 2015 Elsevier Ltd. All rights reserved.

To assess the prevalence of verbally and physically aggressive behaviors in dating relationships in a sample of Spanish adolescents. Cross-sectional self-report data were obtained with The Modified Conflict Tactics Scale (MCTS) from a representative sample of 2416 adolescents and young adults of both genders, between ages of 16 and 20 years. The results showed that a significantly higher percentage of women engaged in verbal aggression (95.3% vs. 92.8%), whereas the males engaged in more severe physical aggression (4.6% vs. 2.0%) and produced worse consequences for their female partners' health (especially slight cuts/slight bruises, broken nose, black eye, broken bone and requiring medical treatment/hospitalization). Justification for aggression also revealed differential results. Whereas women said they attacked their partners while under the influence of emotional states of intense anger (22.4% vs. 13.9%), the males said they did so in response to aggression received (13.0% vs. 6.6%). The analysis of the group differences as a function of age showed that verbal aggression was very high and was not different across the age groups. In contrast, physical aggression decreased significantly across the age groups, but health consequences became more severe with age (e.g., broken nose, black eye, broken bone, went from 1% at 16 years to 4.5% at 20 years of age). These differential tendencies of aggression typology for men and women help clinicians to develop preventive interventions for every age, with the aim of diminishing their continuity in future relationships.

Our objectives were to describe and test refined procedures for quantifying excreta produced from whole pens of dairy heifers. Previous research efforts attempting to make whole-pen measurements of excreta output have been complicated by the use of organic bedding, which requires cumbersome analytical techniques to quantify excreta apart from the bedding. Research pens equipped with sand-bedded freestalls offer a unique opportunity for refinement of whole-pen fecal collection methods, primarily because sand-bedded freestall systems contain no organic bedding; therefore, concentrations of ash within the manure, sand, and feces can be used to correct for contamination of manure by sand bedding. This study was conducted on a subset of heifers from a larger production-scale feeding trial evaluating ensiled eastern gamagrass [Tripsacum dactyloides (L.) L.] haylage (EGG) that was incorporated into a corn silage/alfalfa haylage-based blended diet at rates of 0, 9.1, 18.3, or 27.4% of total DM. The diet without EGG also was offered on a limit-fed basis. Eighty Holstein dairy heifers were blocked (heavy weight, 424 ± 15.9 kg; light weight, 324 ± 22.4 kg) and then assigned to 10 individual pens containing 8 heifers/pen. One pen per block was assigned to each of the 5 research diets, and whole-pen fecal collections were conducted twice for each pen. Grab fecal samples also were gathered from individual heifers within each pen, and subsequent analysis of these whole-pen composites allowed reasonable estimates of OM and NDF excreta output. Under the conditions of our experimental design, pooled SEM for the excreta DM, OM, NDF, and NDF (ash corrected) output were 0.113, 0.085, 0.093, and 0.075 kg·heifer(-1)·d(-1), respectively. For DM excretion, this represented about one-third of the SEM reported for previous whole-pen collections from bedded-pack housing systems. Subsequent calculations of apparent DM and OM digestibilities indicated that the technique was sensitive, and

Past aggression is a potent predictor of future aggression and informs the prediction of violent criminal recidivism. However, aggression is a heterogeneous construct and different types of aggression may confer different levels of risk for future violence. In this prospective study of 91 adults in a pretrial diversion program, we examined a) premeditated versus impulsive aggression in the prediction of violent recidivism during a one-year follow-up period, and b) whether either type of aggression would have incremental validity in the prediction of violent recidivism after taking into account frequency of past general aggression. Findings indicate that premeditated, but not impulsive, aggression predicts violent recidivism. Moreover, premeditated aggression remained a predictor of recidivism even with general aggression frequency in the model. Results provide preliminary evidence that the assessment of premeditated aggression provides relevant information for the management of violent offenders. PMID:25043811

Previous research has indicated that peer popularity is associated with aggressive behavior. However, it is not yet clear whether popularity is uniquely related to different functions of aggression. In this study, we examined associations between peer-perceived popularity, and reactive and proactive aggression using a cross-sectional and a longitudinal design. Yearly sociometric measures of popularity, and reactive and proactive aggression were gathered from 266 seventh and eight grade adolescents (Mage grade 7 = 12.80, SDage  = .40). Popularity was positively correlated with proactive aggression and negatively correlated with reactive aggression, both concurrently as over time. Curvilinear trends indicated that a significant minority of low versus high popular adolescents showed both functions of aggression. Somewhat stronger effects of popularity on proactive aggression were found for boys than girls. Stably popular adolescents showed the highest levels of proactive aggression, whereas stably unpopular youth showed the highest levels of reactive aggression. Implications and directions for future research are discussed. © 2015 Wiley Periodicals, Inc.

The Cyber Aggression in Relationships Scale: A New Multidimensional Measure of Technology-Based Intimate Partner Aggression.

PubMed

Watkins, Laura E; Maldonado, Rosalita C; DiLillo, David

2018-07-01

The purpose of this study was to develop and provide initial validation for a measure of adult cyber intimate partner aggression (IPA): the Cyber Aggression in Relationships Scale (CARS). Drawing on recent conceptual models of cyber IPA, items from previous research exploring general cyber aggression and cyber IPA were modified and new items were generated for inclusion in the CARS. Two samples of adults 18 years or older were recruited online. We used item factor analysis to test the factor structure, model fit, and invariance of the measure structure across women and men. Results confirmed that three-factor models for both perpetration and victimization demonstrated good model fit, and that, in general, the CARS measures partner cyber aggression similarly for women and men. The CARS also demonstrated validity through significant associations with in-person IPA, trait anger, and jealousy. Findings suggest the CARS is a useful tool for assessing cyber IPA in both research and clinical settings.

Evaluation of aggression in Australian after-hours doctor home-visit services.

Minimizing the risks and distress arising from aggression in after-hours house call (AHHC) services will help improve service quality in the industry. Unfortunately, no national study has ever evaluated this in Australian AHHCs. Apart from reducing this gap, findings from this work will have global relevance given the rising popularity of the AHHC industry worldwide. A survey of all 300 doctors employed by the National Home Doctor Service, Australia's largest AHHC service provider. A validated electronic questionnaire was used to examine the doctors' experiences over a 12-month period. There were 168 valid responses (56% response rate). Aggression prevalence was 47.1%, and just over half (51.8%) of the cases came from the patients. "Verbal aggression" was the commonest (48.3%). Others are "threats" (26.6%), "vexatious complaints" (13.3%), "property damage" (4.2%), "physical violence" (4.2%), "sexual harassment" (2.8%), and "stalking" (0.7%). Majority of the respondents were concerned (90.2%) and apprehensive (75.2%) regarding the risks. Doctors who have experienced aggression were more likely to express apprehension (OR = 3.99; CI = 1.54-10.31; P = 0.004), while those that have attained Postgraduate Fellowships (Vocationally Registered) were less likely to report experiences of aggression (OR = 0.28; CI = 0.09-0.84; P = 0.02). Even though a higher proportion of females were concerned (92.3% vs 89.6%) and apprehensive (82.1% vs 73.6%) compared with males, these differences were not statistically significant (Fisher's Exact Tests: P = 1.000 and 0.469, respectively). Aggression in Australian AHHC affects nearly 1-in-2 practitioners, with high levels of concern and apprehension being expressed. Concerned companies should do more to ensure that their doctors attain PG fellowships, as this is linked to lower reports of aggression. Where possible, family and friends need to be involved in patient care, as nearly half of the reported aggressions come from

Objectives Multi-unit housing environments remain significant sources of secondhand smoke (SHS) exposure, especially for vulnerable populations in subsidized housing. In Philadelphia, the largest US housing authority to implement smoke-free policies, we measured baseline resident smoking-related behaviors and attitudes, and longitudinal exposures to airborne nicotine, during policy development and implementation. Methods In 4 communities, we collected data in 2013, 2014, and 2016, before and after introduction of comprehensive smoke-free policies, interviewing persons in 172 households, and monitoring air-borne nicotine in non-smoking homes and public areas. Average nicotine level differences across years were estimated with multi-level models. Results Fifty-six percent of respondents smoked. Only 37% of households were smoke-free, with another 41% restricting smoking by area or time of day. The number of locations with detectable nicotine did not differ before and after policy implementation, with approximately 20% of non-smoking homes and 70%–80% of public areas having detectable nicotine. However, public area nicotine levels were lower in 2016, after policy implementation, than in 2013 and 2014 (−0.19 μg/m3, p = .03). Conclusions Findings suggest that initial policy implementation was associated with reduced SHS exposure in Philadelphia. As HUD strengthens smoke-free policies, SHS monitoring can be useful to educate stakeholders and build support for policy enforcement. PMID:28944277

OBJECTIVES To determine if aggressive treatment initiated early in the course of rheumatoid factor positive or negative polyarticular juvenile idiopathic arthritis (poly-JIA) can induce clinical inactive disease (CID) within 6 months. METHODS Between May 2007 and October 2010 a multi-center, prospective, double blind, randomized, placebo controlled trial of two aggressive treatments was conducted in 85 children aged 2 to 16 years with polyarticular JIA of less than 12 months duration. Patients received either methotrexate 0.5 mg/kg/wk SQ (40 mg max), etanercept 0.8 mg/kg/wk (50 mg max), prednisolone 0.5 mg/kg/d (60 mg max) tapered to 0 by 17 weeks (Arm 1), or methotrexate (same dose as Arm 1), etanercept placebo, and prednisolone placebo (Arm 2). The primary outcome was CID at 6 months. An exploratory phase determined the rate of clinical remission on medication (6 months of continuous CID) at 12 months. RESULTS By 6 months, 17 of 42 (40%) of patients in Arm 1 and 10 of 43 (23%) in Arm 2 had achieved CID (X2 = 2.91; p = 0.088). After 12 months, 9 patients in Arm 1 and 3 in Arm 2 achieved clinical remission on medication (p = 0.0534). There were no significant inter-arm differences in adverse events. CONCLUSIONS Although this study did not meet its primary endpoint, early aggressive therapy in this cohort of children with recent onset polyarticular JIA resulted in substantial proportions of patients in both arms achieving CID by 6 months and clinical remission on medication within 12 months of treatment.

A 16-year-old boy, who had been initially examined for bilateral blepharedema and slight eruption, presented with rapidly deteriorating symptoms in associating with headache and consciousness disturbance. He was diagnosed to have primary cutaneous CD8-positive aggressive epidermotropic cytotoxic T-cell lymphoma (PCAE-CTL) by a biopsy of the skin and brain. After whole-brain radiation and some courses of chemotherapy, cord blood transplantation was performed with myeloablative conditioning. After transplantation, the cerebral dysfunction gradually improved. Disease remission was confirmed by the disappearance of any abnormal findings on electroencephalogram and magnetic resonance imaging. PCAE-CTL is reported to be an extremely aggressive disease with a poor prognosis, but the timely performance of cord blood transplantation is considered to be a promising treatment strategy.

Reciprocal influences between maternal discipline techniques and aggression in children and adolescents.

Sheehan, Michael J; Watson, Malcolm W

2008-01-01

Most studies assessing the link between parental discipline and child aggression have focused primarily on discipline as a cause and aggression as an outcome. In addition to the pathway from discipline to aggression, however, aggressive behavior on the part of the child may lead to future use of discipline by the parent. In this study, structural equation modeling was used to assess reciprocal influences over time between a mothers' use of discipline and aggression in children. Data were drawn from the Springfield Child Development Project, a longitudinal study of middle childhood and adolescence, focusing on antecedents of aggression. The original sample consisted of 440 mother-child dyads living in the city of Springfield, MA. Children in the sample were between 7 and 14 years of age at the first data collection period and between 12 and 19 years of age at the final data collection period. Four hypotheses were tested: (1) a mother's use of aggressive discipline predicts an increase in later child aggression, (2) child aggression predicts an increase in later use of aggressive discipline, (3) the use of reasoning predicts a decrease in later child aggression, and (4) child aggression predicts an increase in later use of reasoning. All hypotheses except number 3 were supported to some degree. Results suggest that children's early aggressive behavior leads to an increase in their mothers' use of both reasoning and aggressive discipline; in turn, increased use of aggressive discipline leads to an increase in aggression during both childhood and adolescence.

Neurogenomic Mechanisms of Aggression in Songbirds

Maney, Donna L.; Goodson, James L.

2017-01-01

Our understanding of the biological basis of aggression in all vertebrates, including humans, has been built largely upon discoveries first made in birds. A voluminous literature now indicates that hormonal mechanisms are shared between humans and a number of avian species. Research on genetics mechanisms in birds has lagged behind the more typical laboratory species because the necessary tools have been lacking until recently. Over the past 30 years, three major technical advances have propelled forward our understanding of the hormonal, neural, and genetic bases of aggression in birds: (1) the development of assays to measure plasma levels of hormones in free-living individuals, or “field endocrinology”; (2) the immunohistochemical labeling of immediate early gene products to map neural responses to social stimuli; and (3) the sequencing of the zebra finch genome, which makes available a tremendous set of genomic tools for studying gene sequences, expression, and chromosomal structure in species for which we already have large datasets on aggressive behavior. This combination of hormonal, neuroendocrine, and genetic tools has established songbirds as powerful models for understanding the neural basis and evolution of aggression in vertebrates. In this chapter, we discuss the contributions of field endocrinology toward a theoretical framework linking aggression with sex steroids, explore evidence that the neural substrates of aggression are conserved across vertebrate species, and describe a promising new songbird model for studying the molecular genetic mechanisms underlying aggression.

Aggression in toddlers: associations with parenting and marital relations.

Brook, J S; Zheng, L; Whiteman, M; Brook, D W

2001-06-01

This study examined the relation among parenting factors, marital relations, and toddler aggression. A structured questionnaire was administered to both parents of 254 2-year-olds. The authors used correlation and hierarchical multiple regression analyses to assess the extent to which certain personality traits, drug use, parenting style, and marital conflicts were related to the toddlers' aggressive behavior. Results showed that the maternal child-rearing and parental aggression domains had a direct effect on toddler aggression. The domain of maternal child rearing also served as a mediator for the domains of marital relations, paternal child rearing, parental aggression, and parental drug use. The findings indicated that maternal child-rearing practices, personality attributes, and drug use were more important than paternal attributes in relation to toddler aggression. Implications for prevention among families at risk are discussed.

Although the genus Clavibacter was originally proposed to accommodate all phytopathogenic coryneform bacteria containing B2γ diaminobutyrate in the peptidoglycan, reclassification of all but one species into other genera has resulted in the current monospecific status of the genus. The single species in the genus, Clavibacter michiganensis, has multiple subspecies, which are all highly host-specific plant pathogens. Whole genome analysis based on average nucleotide identity and digital DNA-DNA hybridization as well as multi-locus sequence analysis (MLSA) of seven housekeeping genes support raising each of the C. michiganensis subspecies to species status. On the basis of whole genome and MLSA data, we propose the establishment of two new species and three new combinations: Clavibacter capsici sp. nov., comb. nov. and Clavibacter tessellarius sp. nov., comb. nov., and Clavibacter insidiosus comb. nov., Clavibacter nebraskensis comb. nov. and Clavibacter sepedonicus comb. nov.

Motivational drive and alprazolam misuse: A recipe for aggression?

2016-06-30

Benzodiazepine-related aggression has received insufficient research attention, in particular little is known about the motivational factors which may contribute to the development of this paradoxical response. The revised Reinforcement Sensitivity Theory provides a theoretical framework from which to understand the relevant underlying motivational processes. The current study aimed to identify the role of approach and avoidance motivational tendencies in the occurrence of benzodiazepine-related aggression. Data regarding benzodiazepine and other substance use, approach and avoidance motivation, and general and physical aggressive behaviour were collected via self-report questionnaires. Participants were a convenience sample (n=204) who reported using benzodiazepines in the previous year. Participants were primarily male (62.7%), aged 18-51 years old. Hierarchical multiple regressions indicated that general and physical aggression were predicted by alprazolam use and Drive, a facet of approach motivation. Overall, lower diazepam use significantly predicted higher levels of general aggression. However, when diazepam-preferring participants were examined in isolation of the larger sample (23.5% of sample), problematic (dependent) diazepam use was associated with greater aggression scores, as was dependence risk for alprazolam-preferring participants (39.7% of sample). The findings highlight the importance of motivational factors and benzodiazepine use patterns in understanding benzodiazepine-related aggression, with implications for violent offender rehabilitation.

Bad nights or bad bars? Multi-level analysis of environmental predictors of aggression in late-night large-capacity bars and clubs.

2006-11-01

To clarify environmental predictors of bar-room aggression by differentiating relationships due to nightly variations versus across bar variations, frequency versus severity of aggression and patron versus staff aggression. Male-female pairs of researcher-observers conducted 1334 observations in 118 large capacity (> 300) bars and clubs in Toronto, Canada. Observers independently rated aspects of the environment (e.g. crowding) at every visit and wrote detailed narratives of each incident of aggression that occurred. Measures of severity of aggression for the visit were calculated by aggregating ratings for each person in aggressive incidents. Although bivariate analyses confirmed the significance of most environmental predictors of aggression identified in previous research, multivariate analyses identified the following key visit-level predictors (controlling for bar-level relationships): rowdiness/permissive environment and people hanging around after closing predicted both frequency and severity of aggression; sexual activity, contact and competition and people with two or more drinks at closing predicted frequency but not severity of aggression; lack of staff monitoring predicted more severe patron aggression, while having more and better coordinated staff predicted more severe staff aggression. Intoxication of patrons was significantly associated with more frequent and severe patron aggression at the bar level (but not at the visit level) in the multivariate analyses and negatively associated with severity of staff aggression at the visit level. The results demonstrate clearly the importance of the immediate environment (not just the type of bar or characteristics of usual patrons) and the importance of specific environmental factors, including staff behaviour, in predicting both frequency and severity of aggression.

A three-year study (1999-2001) was initiated in the UK to assess the effect of improving housing conditions in 3-4 bedroom, single-family unit, social rented sector houses on the health of the occupants. The houses were randomised into two groups. Phase I houses received extensive upgrading including wet central heating, on demand ventilation, double-glazed doors, cavity wall and roof/loft insulation. An identical intervention for Phase II houses was delayed for one year. As part of this randomised waiting list study, discrete measurements were made of indoor environmental variables in each house, to assess the short-term effects of improving housing conditions on the indoor environment. Variables representative of indoor environmental conditions were measured in the living room, bedroom and outdoors in each of the three years of the study. In 2000, there was a significant difference between the changes from 1999 to 2000 between Phase I (upgraded) and II (not then upgraded) houses for bedroom temperatures (p=0.002). Changes in wall surface dampness and wall dampness in Phase I houses were also significantly different to the change in Phase II houses in 2000 (p=0.001), but by 2001 the Phase I houses had reverted to the same dampness levels they had before upgrading. The housing upgrades increased bedroom temperatures in all houses. Other indoor environmental variables were not affected.

Does Humor Explain Why Relationally Aggressive Adolescents Are Popular?

The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents’ gender and their friends’ levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; Mage = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

This study examines whether maternal warmth moderates the association between maternal use of spanking and increased child aggression between ages 1 and 5. Participants were 3,279 pairs of mothers and their children from a cohort study of urban families from 20 U.S. cities. Maternal spanking was assessed when the child was 1 year, 3 years, and 5 years of age. Maternal warmth and child aggressive behavior were measured at 3 years and 5 years of age. Models controlled for demographic characteristics (measured at the child's birth), child emotionality (measured at age 1), and maternal psychosocial risk factors (measured when children were 3 years old). Cross-lagged path models examined the within-time and longitudinal associations between spanking and child aggression. Results indicated that maternal spanking at age 1 was associated with higher levels of child aggression at age 3; similarly, maternal spanking at age 3 predicted increases in child aggression by age 5. Maternal warmth when children were 3 years old did not predict changes in child aggression between 3 and 5 years old. Furthermore, maternal warmth did not moderate the association between spanking and increased child aggression over time. Beginning as early as age 1, maternal spanking is predictive of child behavior problems, and maternal warmth does not counteract the negative consequences of the use of spanking.

Objective The spillover hypothesis suggests that childhood aggression results from spillover of inter-parental conflict to poor parenting, which promotes aggressive child behavior. This study was designed to examine the spillover hypothesis in non-genetically related parent – child dyads from the toddler period through age 6. Method A sample of 361 sets of children, adoptive parents, and birth parents from the Early Growth and Development Study (EGDS) was assessed from child age 9 months to 6 years on measures of adoptive parent financial strain, antisocial traits, marital hostility, hostile parenting, and child aggression. Structural equation modeling was used to examine links from financial strain, parent antisocial traits, and marital hostility in infancy and toddlerhood to hostile parenting and child aggression at age 4.5 and 6 years. Results Spillover of marital conflict from child age 18 to 27 months was associated with more parental hostility in mothers and fathers at 27 months. In turn, adoptive fathers’ parental hostility, but not mothers’, was associated with aggression in children at age 4.5 years. However, there was no significant spillover from hostile parenting at 4.5 years to child aggression at 6 years. Birth mother antisocial traits were unassociated with child aggression. Conclusion This study is the first to examine spillover of marital hostility to parenting to child aggression from toddlerhood through age 6 years in an adoption design, highlighting the impact of these environmental factors from the toddler to preschool period. The findings support the potential benefit of early identification of marital hostility. PMID:26903257

Objective We analyzed the relationship between health status and housing quality over time. Methods We combined data from two nationally representative longitudinal surveys of the U.S. population and its housing, the National Health and Nutrition Examination Survey and the American Housing Survey, respectively. We identified housing and health trends from approximately 1970 to 2000, after excluding those trends for which data were missing or where we found no plausible association or change in trend. Results Changes in housing include construction type, proportion of rental versus home ownership, age, density, size, moisture, pests, broken windows, ventilation and air conditioning, and water leaks. Changes in health measures include asthma, respiratory illness, obesity and diabetes, and lead poisoning, among others. The results suggest ecologic trends in childhood lead poisoning follow housing age, water leaks, and ventilation; asthma follows ventilation, windows, and age; overweight trends follow ventilation; blood pressure trends follow community measures; and health disparities have not changed greatly. Conclusions Housing trends are consistent with certain health trends over time. Future national longitudinal surveys should include health, housing, and community metrics within a single integrated design, instead of separate surveys, in order to develop reliable indicators of how housing changes affect population health and how to best target resources. Little progress has been made in reducing the health and housing disparities of disadvantaged groups, with the notable exception of childhood lead poisoning caused by exposure to lead-based paint hazards. Use of these and other data sets to create reliable integrated indicators of health and housing quality are needed. PMID:19440499

Distinguishing between relational and physical aggression has become a key feature of many developmental studies in North America and Western Europe, but very little information is available on relational aggression in more diverse cultural contexts. This study examined the factor structure of, gender differences in, and associations between relational and physical aggression in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Children ages 7 to 10 years (N = 1410) reported on their relationally and physically aggressive behavior. Relational and physical aggression shared a common factor structure across countries. Unsurprisingly, boys reported being more physically aggressive than girls across all nine countries; surprisingly, there were no significant gender differences in relational aggression. In all nine countries, relational and physical aggression were significantly correlated (average r = .49). The countries differed significantly in the mean levels of both relational and physical aggression that children reported using and with respect to whether children reported using more physical than relational aggression or more relational than physical aggression. Despite mean level differences in relational and physical aggression across countries, the findings provided support for cross-country similarities in associations between relational and physical aggression, as well as links between gender and aggression.

To examine the use of the Prostate Health Index (PHI) as a continuous variable in multivariable risk assessment for aggressive prostate cancer in a large multicentre US study. The study population included 728 men, with prostate-specific antigen (PSA) levels of 2-10 ng/mL and a negative digital rectal examination, enrolled in a prospective, multi-site early detection trial. The primary endpoint was aggressive prostate cancer, defined as biopsy Gleason score ≥7. First, we evaluated whether the addition of PHI improves the performance of currently available risk calculators (the Prostate Cancer Prevention Trial [PCPT] and European Randomised Study of Screening for Prostate Cancer [ERSPC] risk calculators). We also designed and internally validated a new PHI-based multivariable predictive model, and created a nomogram. Of 728 men undergoing biopsy, 118 (16.2%) had aggressive prostate cancer. The PHI predicted the risk of aggressive prostate cancer across the spectrum of values. Adding PHI significantly improved the predictive accuracy of the PCPT and ERSPC risk calculators for aggressive disease. A new model was created using age, previous biopsy, prostate volume, PSA and PHI, with an area under the curve of 0.746. The bootstrap-corrected model showed good calibration with observed risk for aggressive prostate cancer and had net benefit on decision-curve analysis. Using PHI as part of multivariable risk assessment leads to a significant improvement in the detection of aggressive prostate cancer, potentially reducing harms from unnecessary prostate biopsy and overdiagnosis. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

Laboratories working towards accreditation by the International Standards Organization (ISO) 15189 standard are required to demonstrate the validity of their analytical methods. The different guidelines set by various accreditation organizations make it difficult to provide objective evidence that an in-house method is fit for the intended purpose. Besides, the required performance characteristics tests and acceptance criteria are not always detailed. The laboratory must choose the most suitable validation protocol and set the acceptance criteria. Therefore, we propose a validation protocol to evaluate the performance of an in-house method. As an example, we validated the process for the detection and quantification of lead in whole blood by electrothermal absorption spectrometry. The fundamental parameters tested were, selectivity, calibration model, precision, accuracy (and uncertainty of measurement), contamination, stability of the sample, reference interval, and analytical interference. We have developed a protocol that has been applied successfully to quantify lead in whole blood by electrothermal atomic absorption spectrometry (ETAAS). In particular, our method is selective, linear, accurate, and precise, making it suitable for use in routine diagnostics.

Although the ubiquitin-editing enzyme A20 is a key player in inflammation and autoimmunity, its role in cancer metastasis remains unknown. Here we show that A20 monoubiquitylates Snail1 at three lysine residues and thereby promotes metastasis of aggressive basal-like breast cancers. A20 is significantly upregulated in human basal-like breast cancers and its expression level is inversely correlated with metastasis-free patient survival. A20 facilitates TGF-β1-induced epithelial-mesenchymal transition (EMT) of breast cancer cells through multi-monoubiquitylation of Snail1. Monoubiquitylated Snail1 has reduced affinity for glycogen synthase kinase 3β (GSK3β), and is thus stabilized in the nucleus through decreased phosphorylation. Knockdown of A20 or overexpression of Snail1 with mutation of the monoubiquitylated lysine residues into arginine abolishes lung metastasis in mouse xenograft and orthotopic breast cancer models, indicating that A20 and monoubiquitylated Snail1 are required for metastasis. Our findings uncover an essential role of the A20-Snail1 axis in TGF-β1-induced EMT and metastasis of basal-like breast cancers.

One-sided and mutually aggressive couples: Differences in attachment, conflict prevalence, and coping.

This study investigated concurrent links between adolescent romantic couples' reports of aggression (relational and physical) and relationship functioning (e.g., attachment security, conflict prevalence, coping strategies, jealousy, and affiliative and romantic relationship quality) using a pattern-oriented approach. The sample included 194 romantic partner dyads (Mage=16.99 years for females and Mage=18.41 years for males). A hierarchical cluster analysis identified five distinct subgroups of dyads based on male and female reports of relational and physical aggression, ranging from nonaggressive couples (42%), to those characterized by aggressive females (18%), aggressive males (14%), physically aggressive females (20%), and mutually aggressive females and males (6%). Clusters in which one partner was perceived as either relationally or physically aggressive were characterized by higher rates of conflict, less adaptive coping, and more jealousy (particularly in males). The mutually aggressive couples showed the least adaptive relationship functioning, with high rates of conflict, a deficit in reflection and emotion regulation in conflict situations, and a lack of affiliative relationship qualities. The discussion focuses on the formative character of aggression in these early romantic relations, the aggravating impact of mutual aggression on relationship functioning, and the gender-specific functions of aggression in relationships characterized by unilateral aggression.

Runions, Kevin C; Bak, Michal; Shaw, Thérèse

2017-01-01

Aggression in online contexts has received much attention over the last decade, yet there is a need for measures identifying the proximal psychological drivers of cyber-aggressive behavior. The purpose of this study was to present data on the newly developed Cyber-Aggression Typology Questionnaire (CATQ) designed to distinguish between four distinct types of cyber-aggression on dimensions of motivational valence and self-control. A sample 314 undergraduate students participated in the study. The results confirmed the predicted four-factor structure providing evidence for distinct and independent impulsive-aversive, controlled-aversive, impulsive-appetitive, and controlled-appetitive cyber-aggression types. Further analyses with the Berlin Cyberbullying Questionnaire, Reactive Proactive Aggression Questionnaire, and the Behavior Inhibition and Activation Systems Scale provide support for convergent and divergent validity. Understanding the motivations facilitating cyber-aggressive behavior could aid researchers in the development of new prevention and intervention strategies that focus on individual differences in maladaptive proximal drivers of aggression.

Patients with hepatocellular carcinoma (HCC) have a high-risk of multi-centric (MC) tumor occurrence due to a strong carcinogenic background in the liver. In addition, they have a high risk of intrahepatic metastasis (IM). Liver tumors withIM or MC are profoundly different in their development and clinical outcome. However, clinically or pathologically discriminating between IM and MC can be challenging. This study investigated whether IM or MC could be diagnosed at the molecular level. We performed whole genome and RNA sequencing analyses of 49 tumors including two extra-hepatic metastases, and one nodule-in-nodule tumor from 23 HCC patients. Sequencing-based molecular diagnosis using somatic single nucleotide variation information showed higher sensitivity compared to previous techniques due to the inclusion of a larger number of mutation events. This proved useful in cases, which showed inconsistent clinical diagnoses. In addition, whole genome sequencing offered advantages in profiling of other genetic alterations, such as structural variations, copy number alterations, and variant allele frequencies, and helped to confirm the IM/MCdiagnosis. Divergent alterations between IM tumors with sorafenib treatment, long time-intervals, or tumor-in-tumor nodules indicated high intra-tumor heterogeneity, evolution, and clonal switching of liver cancers. It is important to analyze the differences between IM tumors, in addition to IM/MC diagnosis, before selecting a therapeutic strategy for multiple tumors in the liver. Whole genome sequencing of multiple liver tumors enabled the accuratediagnosis ofmulti-centric occurrence and intrahepatic metastasis using somatic single nucleotide variation information. In addition, genetic discrepancies between tumors help us to understand the physical changes during recurrence and cancer spread. Copyright © 2016 European Association for the Study of the Liver.

Whole-body iron transport and metabolism: Mechanistic, multi-scale model to improve treatment of anemia in chronic kidney disease

PubMed Central

Sarkar, Joydeep

2018-01-01

Iron plays vital roles in the human body including enzymatic processes, oxygen-transport via hemoglobin and immune response. Iron metabolism is characterized by ~95% recycling and minor replenishment through diet. Anemia of chronic kidney disease (CKD) is characterized by a lack of synthesis of erythropoietin leading to reduced red blood cell (RBC) formation and aberrant iron recycling. Treatment of CKD anemia aims to normalize RBC count and serum hemoglobin. Clinically, the various fluxes of iron transport and accumulation are not measured so that changes during disease (e.g., CKD) and treatment are unknown. Unwanted iron accumulation in patients is known to lead to adverse effects. Current whole-body models lack the mechanistic details of iron transport related to RBC maturation, transferrin (Tf and TfR) dynamics and assume passive iron efflux from macrophages. Hence, they are not predictive of whole-body iron dynamics and cannot be used to design individualized patient treatment. For prediction, we developed a mechanistic, multi-scale computational model of whole-body iron metabolism incorporating four compartments containing major pools of iron and RBC generation process. The model accounts for multiple forms of iron in vivo, mechanisms involved in iron uptake and release and their regulation. Furthermore, the model is interfaced with drug pharmacokinetics to allow simulation of treatment dynamics. We calibrated our model with experimental and clinical data from peer-reviewed literature to reliably simulate CKD anemia and the effects of current treatment involving combination of epoietin-alpha and iron dextran. This in silico whole-body model of iron metabolism predicts that a year of treatment can potentially lead to 90% downregulation of ferroportin (FPN) levels, 15-fold increase in iron stores with only a 20% increase in iron flux from the reticulo-endothelial system (RES). Model simulations quantified unmeasured iron fluxes, previously unknown effects of

This report describes the long-term outcomes of nonsurgical periodontal therapy and supportive periodontal treatment (SPT) of a 21-year-old patient affected by generalized aggressive periodontitis at multiple teeth with a compromised prognosis. After 25 years of SPT, no teeth had been extracted and no periodontal pockets associated with bleeding on probing were present. Radiographic analysis showed an improvement in infrabony defects, demonstrating long-term improvement is possible with nonsurgical periodontal treatment provided that smoking is not present and the patient is included in a strict SPT.

Although the genus Clavibacter was originally proposed to accommodate all phytopathogenic coryneform bacteria containing B2γ diaminobutyrate in the peptidoglycan, reclassification of all but one species into other genera has resulted in the current monospecific status of the genus. The single species in the genus, Clavibacter michiganensis, has multiple subspecies, which are all highly host-specific plant pathogens. Whole genome analysis based on average nucleotide identity and digital DNA–DNA hybridization as well as multi-locus sequence analysis (MLSA) of seven housekeeping genes support raising each of the C. michiganensis subspecies to species status. On the basis of whole genome and MLSA data, we propose the establishment of two new species and three new combinations: Clavibacter capsici sp. nov., comb. nov. and Clavibacter tessellarius sp. nov., comb. nov., and Clavibacter insidiosus comb. nov., Clavibacter nebraskensis comb. nov. and Clavibacter sepedonicus comb. nov.

Mortality rates among these people were substantially higher than rates in the poorest income fifth, with the highest rate ratios seen at younger ages. Among those who were homeless or marginally housed, the probability of survival to age 75 was 32% (95% confidence interval 30% to 34%) in men and 60% (56% to 63%) in women. Remaining life expectancy at age 25 was 42 years (42 to 43) and 52 years (50 to 53), respectively. Compared with the entire cohort, mortality rate ratios for men and women, respectively, were 11.5 (8.8 to 15.0) and 9.2 (5.5 to 15.2) for drug related deaths, 6.4 (5.3 to 7.7) and 8.2 (5.0 to 13.4) for alcohol related deaths, 4.8 (3.9 to 5.9) and 3.8 (2.7 to 5.4) for mental disorders, and 2.3 (1.8 to 3.1) and 5.6 (3.2 to 9.6) for suicide. For both sexes, the largest differences in mortality rates were for smoking related diseases, ischaemic heart disease, and respiratory diseases. Living in shelters, rooming houses, and hotels is associated with much higher mortality than expected on the basis of low income alone. Reducing the excessively high rates of premature mortality in this population would require interventions to address deaths related to smoking, alcohol, and drugs, and mental disorders and suicide, among other causes.

Focus on aggressive behaviour in mental illness.

2017-01-01

Aggression is a behaviour with evolutionary origins, but in today’s society it is often both destructive and maladaptive. Increase of aggressive behaviour has been observed in a number of serious mental illnesses, and it represents a clinical challenge for mental healthcare provider. These phenomena can lead to harmful behaviours, including violence, thus representing a serious public health concern. Aggression is often a reason for psychiatric hospitalization, and it often leads to prolonged hospital stays, suffering by patients and their victims, and increased stigmatization. Moreover, it has an effect on healthcare use and costs in terms of longer length of stay, more readmissions and higher drug use. In this review, based on a selective search of 2010-2016 pertinent literature on PubMed, we analyze and summarize information from original articles, reviews, and book chapters about aggression and psychiatric disorders, discussing neurobiological basis and therapy of aggressive behaviour. A great challenge has been revealed regarding the neurobiology of aggression, and an integration of this body of knowledge will ultimately improve clinical diagnostics and therapeutic interventions. The great heterogeneity of aggressive behaviour still hampers our understanding of its causal mechanisms. Still, over the past years, the identification of specific subtypes of aggression has released possibilities for new and individualized treatment approaches. Neuroimaging studies may help to further elucidate the interrelationship between neurocognitive functioning, personality traits, and antisocial and violent behaviour. Recent studies point toward manipulable neurobehavioral targets and suggest that cognitive, pharmacological, neuromodulatory, and neurofeedback treatment approaches can be developed to ameliorate urgency and aggression in schizophrenia. These combined approaches could improve treatment efficacy. As current pharmacological and therapeutic interventions are

To evaluate MRI derived whole-tumour histogram analysis parameters in predicting pancreatic neuroendocrine neoplasm (panNEN) grade and aggressiveness. Pre-operative MR of 42 consecutive patients with panNEN >1 cm were retrospectively analysed. T1-/T2-weighted images and ADC maps were analysed. Histogram-derived parameters were compared to histopathological features using the Mann-Whitney U test. Diagnostic accuracy was assessed by ROC-AUC analysis; sensitivity and specificity were assessed for each histogram parameter. ADC entropy was significantly higher in G2-3 tumours with ROC-AUC 0.757; sensitivity and specificity were 83.3 % (95 % CI: 61.2-94.5) and 61.1 % (95 % CI: 36.1-81.7). ADC kurtosis was higher in panNENs with vascular involvement, nodal and hepatic metastases (p= .008, .021 and .008; ROC-AUC= 0.820, 0.709 and 0.820); sensitivity and specificity were: 85.7/74.3 % (95 % CI: 42-99.2 /56.4-86.9), 36.8/96.5 % (95 % CI: 17.2-61.4 /76-99.8) and 100/62.8 % (95 % CI: 56.1-100/44.9-78.1). No significant differences between groups were found for other histogram-derived parameters (p >.05). Whole-tumour histogram analysis of ADC maps may be helpful in predicting tumour grade, vascular involvement, nodal and liver metastases in panNENs. ADC entropy and ADC kurtosis are the most accurate parameters for identification of panNENs with malignant behaviour. • Whole-tumour ADC histogram analysis can predict aggressiveness in pancreatic neuroendocrine neoplasms. • ADC entropy and kurtosis are higher in aggressive tumours. • ADC histogram analysis can quantify tumour diffusion heterogeneity. • Non-invasive quantification of tumour heterogeneity can provide adjunctive information for prognostication.

Patients younger than 55 years of age with papillary thyroid carcinoma (PTC) have excellent survival. Diffuse sclerosing variant (DSV) and tall cell variant (TCV) of PTC are associated with aggressiveness; the survival of patients <55 years of age with these variants is still unclear. We aim to investigate the clinicopathological features and survival of these variants in the age group <55 years. All adult patients (<55 years old) with DSV, TCV and conventional PTC (CPTC) came from the Surveillance, Epidemiology, and End Results program (1988-2013). Kaplan-Meier method and log-rank test were used to analyze the survival. Prognostic factors associated with survival were analyzed by Cox multivariate regression. There were 280 DSV, 615 TCV, and 56287 CPTC in the age group <55 years. DSV and TCV were associated with multifocality, extrathyroidal extension, lymph node and distant metastasis (all p < 0.05). The 10-year disease-specific survival (DSS) of TCV was worse than CPTC (96.3 vs. 99.4%, p < 0.01), but there was no significant difference between DSV and CPTC (99.5 vs. 99.4%, p > 0.05). Cox multivariate regression showed TCV was the independent predictor of DSS (HR: 5.39, p < 0.01). In the age group <55 years, DSV and TCV are more likely to exhibit aggressive characteristics than CPTC. Patient <55 years of age with DSV have excellent survival likewise, while patients <55 years of age with TCV carry worse survival. Further investigation for the recurrence risk of patients <55 years with these variants would contribute to optimal clinical management making.

Previous studies that operationalized reactive aggression using behavioral observations in general populations have not taken into account the type of stimulus that elicits reactive aggression. In the present study we define a specific form of reactive aggression, i.e., reactive aggression in response to neutral behavior of a peer, which we will call unprovoked reactive aggression. We were specifically interested in children with severe aggressive behavior problems, since they may respond with reactive aggression even though the opponent did not clearly provoke them, but instead showed neutral behavior. Children with a disruptive behavior disorder (DBD) and normal control (NC) children participated in separate play sessions in which they played with a normal peer (NP). Children with DBD showed more unprovoked reactive aggression than NC children, during a cooperative game. Moreover, for children with DBD, unprovoked reactive aggressive behavior in this game correlated with parent-rated reactive aggression. Results of this study suggest that an unprovoked reactive form of aggression can be identified in children with DBD. Copyright (c) 2008. Published by Elsevier Ireland Ltd.

Due to its potential environmental and public health impacts, emissions of ammonia (NH3) as well as several other gases from US livestock farms may be regulated. Broiler houses are important sources of NH3 emissions. However, there are no emissions data from roaster (8-12 wk old broilers, ˜4 kg ea.) houses. Producers treat the litter in broiler houses with acidifiers, such as sodium bisulfate (SBS, NaHSO4) to reduce ammonia production and protect bird health. However, there is very little data on the effect of acidifiers, particularly at high application rates on ammonia emissions. The impact of different SBS application rates [High (0.95-1.46 kg m-2, whole house), Medium (0.73 kg m-2, whole house), Low (0.37-0.49 kg m-2, whole house), and Control (0.37-0.49 kg m-2, brood chamber)] on ammonia emissions was evaluated in commercial roaster houses over 22 months spanning eight flocks. Ammonia emission from each fan was measured with an acid scrubber that operated only when the fan operated. Emissions were calculated using >95% measured data with the rest being estimated using robust methods. Exhaust ammonia-N concentrations were inversely correlated with the SBS application rates. Emission rates on animal unit (AU, where 1 AU = 500 kg live-mass) basis (ER, g d-1 AU-1) were reduced by 27, 13, and 5%, respectively, in the High, Medium, and Low treatments vs. the Control treatment (mean: 100 g d-1 AU-1, range: 86-114 g d-1 AU-1). Emission rates for the Control treatment measured in this study on roasters were mostly higher than ERs in the literature. Differences in ERs are not only due to diet, environmental and management conditions, but also due to measurement methods.

The purpose of the present study was to extend previous knowledge concerning the link between self-esteem and aggression by examining the mediating role of emotion dysregulation among offenders and community participants. A sample of 153 incarcerated violent offenders and a community sample of 197 individuals completed self-report measures of self-esteem level, emotion dysregulation, and trait aggression. Offenders reported lower levels of self-esteem than community participants, as well as greater levels of emotional nonacceptance and hostility. Bootstrapping analyses were performed to test whether emotion dysregulation mediated the association between self-esteem level and aggression. In the offender sample, mediation models were significant for three of the four aspects of trait aggression that were considered. Emotion dysregulation fully mediated the links that low self-esteem had with physical aggression, anger, and hostility. The same pattern (with the addition of full mediation for verbal aggression) was confirmed in the community sample. Our findings suggest that emotion dysregulation may play an important role in the connection between low self-esteem and aggression. Alternative models of the associations among these variables were tested and discussed. As a whole, the present results are consistent with those of other studies and suggest that it may be beneficial to include emotion regulation modules as part of prevention and treatment programs for violent offenders. © 2015 Wiley Periodicals, Inc.

Empathy and anger are two social emotions that modulate an individual's risk for aggression. Empathy is an emotional reaction to another individual's emotional state. Anger is an emotional reaction to threat, frustration or social provocation. Reduced empathy, seen in psychopathy, increases the risk for goal-directed aggression. Atypically increased anger (i.e. irritability), seen in conditions like disruptive mood dysregulation disorder and borderline personality disorder, increases the risk for reactive aggression. In this paper, I will outline core neurocognitive functions that correspond to empathy and which are compromised in individuals with psychopathic traits. In addition, I will outline neurocognitive functions involved in either the generation or regulation of anger and which are compromised in psychiatric conditions at increased risk for irritability/reactive aggression. It can be hoped that improved understanding of empathy and anger will lead to better assessment tools and improved interventions to reduce aggression risk.This article is part of the theme issue 'Diverse perspectives on diversity: multi-disciplinary approaches to taxonomies of individual differences'. © 2018 The Author(s).

Dating aggression occurs frequently in early to mid-adolescence and has negative repercussions for psychosocial adjustment and physical health. The patterns of behavior learned during this developmental timeframe may persist in future dating relationships, underscoring the need to identify risk factors for this outcome. The current study examined longitudinal relations between beliefs supporting aggression, anger regulation, and dating aggression. Participants were 176 middle school students in sixth, seventh, and eighth grade (50 % female; 82 % African American). No direct effects were found between beliefs supporting reactive or proactive aggression and dating aggression. Beliefs supporting reactive aggression predicted increased rates of anger dysregulation, and beliefs supporting proactive aggression led to subsequent increases in anger inhibition. Anger dysregulation and inhibition were associated with higher frequencies of dating aggression. An indirect effect was found for the relation between beliefs supporting reactive aggression and dating aggression via anger dysregulation. Another indirect effect emerged for the relation between beliefs supporting proactive aggression and dating aggression through anger inhibition. The study's findings suggested that beliefs supporting proactive and reactive aggression were differentially related to emotion regulation processes, and identified anger dysregulation and inhibition as risk factors for dating aggression among adolescents.
