  5. A mechanical model of overnight hair curling.

    PubMed

    Xiao, Hang; Chen, Xi

    2015-09-01

    Based on the observation of overnight hair curling procedure, we establish a mechanical model to describe the temporary wave formation of straight hair (initial curvature is zero), which incorporates the contact between hair and hair roller. Systematic studies are carried out to explore the effects of radius ratio between hair and hair roller, hair's average axial strain, creep time, Poisson's ratio and gravity on the curl retention. The variation of curl retention with respect to time obtained from our numerical model is validated by a simple theoretical model and by overnight curling experiments on hair samples. The results of simulation show that overnight hair curling is suitable to create a wavy hairstyle within about 7 hours, while the combined usage with hair fixatives enables a wavy hairstyle with desired curvature that lasts for a day or more.

    Post-learning sleep is beneficial for human memory. However, it may be that not all memories benefit equally from sleep. Here, we manipulated a spatial learning task using monetary reward and performance feedback, asking whether enhancing the salience of the task would augment overnight memory consolidation and alter its incorporation into dreaming. Contrary to our hypothesis, we found that the addition of reward impaired overnight consolidation of spatial memory. Our findings seemingly contradict prior reports that enhancing the reward value of learned information augments sleep-dependent memory processing. Given that the reward followed a negative reinforcement paradigm, consolidation may have been impaired via a stress-related mechanism.

  8. The overnight effect on the Taiwan stock market

    NASA Astrophysics Data System (ADS)

    Tsai, Kuo-Ting; Lih, Jiann-Shing; Ko, Jing-Yuan

    2012-12-01

    This study examines statistical regularities among three components of stocks and indices: daytime (trading hour) return, overnight (off-hour session) return, and total (close-to-close) return. Owing to the fact that the Taiwan Stock Exchange (TWSE) has the longest non-trading periods among major markets, the TWSE is selected to explore the correlation among the three components and compare it with major markets such as the New York Stock Exchange (NYSE) and the National Association of Securities Dealers Automated Quotation (NASDAQ). Analysis results indicate a negative cross correlation between the sign of daytime return and the sign of overnight return; possibly explaining why most stocks feature a negative cross correlation between daytime return and overnight return [F. Wang, S.-J. Shieh, S. Havlin, H.E. Stanley, Statistical analysis of the overnight and daytime return, Phys. Rev. E 79 (2009) 056109]. Additionally, the cross correlation between the magnitude of returns is analyzed. According to those results, a larger magnitude of overnight return implies a higher probability that the sign of the following daytime return is the opposite of the sign of overnight return. Namely, the predictability of daytime return might be improved when a stock undergoes a large magnitude of overnight return. Furthermore, the cross correlations of 29 indices of worldwide markets are discussed.

  10. 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.

  12. Substantial overnight reaeration by convective cooling discovered in pond ecosystems

    NASA Astrophysics Data System (ADS)

    Holgerson, Meredith A.; Zappa, Christopher J.; Raymond, Peter A.

    2016-08-01

    Trends in freshwater dissolved oxygen (DO) reflect whole-ecosystem properties and influence organismal survival and behavior. Here we show that small ponds have unique oxygen dynamics that differ from larger lakes. We discovered that ponds undersaturated in DO experienced substantial increases in oxygen concentration overnight. Nighttime increases in DO occurred on 45% of the nights sampled and resulted in DO saturation increasing 12-fold (22% saturation) on average. Oxygen spikes were likely to occur when ponds became at least 1.8°C warmer than the air and later in the season when oxygen levels were low (<31% saturation) and the air was warm (≥5.8°C). We demonstrate that overnight increases in surface water DO resulted from atmospheric oxygen invasion as opposed to internal production. Convective cooling enhanced turbulence and air-water gas exchange, leading to intense bursts of oxygen invasion during nighttime hours. This mechanism has not been demonstrated before and has important implications for the biogeochemistry of these systems, as well as understanding how organisms survive in hypoxic small ponds.

  14. Hybrid optimal online-overnight charging coordination of plug-in electric vehicles in smart grid

    Optimal coordinated charging of plugged-in electric vehicles (PEVs) in smart grid (SG) can be beneficial for both consumers and utilities. This paper proposes a hybrid optimal online followed by overnight charging coordination of high and low priority PEVs using discrete particle swarm optimization (DPSO) that considers the benefits of both consumers and electric utilities. Objective functions are online minimization of total cost (associated with grid losses and energy generation) and overnight valley filling through minimization of the total load levels. The constraints include substation transformer loading, node voltage regulations and the requested final battery state of charge levels (SOCreq). The main challenge is optimal selection of the overnight starting time (toptimal-overnight,start) to guarantee charging of all vehicle batteries to the SOCreq levels before the requested plug-out times (treq) which is done by simultaneously solving the online and overnight objective functions. The online-overnight PEV coordination approach is implemented on a 449-node SG; results are compared for uncoordinated and coordinated battery charging as well as a modified strategy using cost minimizations for both online and overnight coordination. The impact of toptimal-overnight,start on performance of the proposed PEV coordination is investigated.

  17. A comparison of overnight and 24 hour collection to measure urinary catecholamines.

    PubMed

    White, I R; Brunner, E J; Barron, J L

    1995-02-01

    The period of urine collection used to measure excretion of catecholamines varies in epidemiological practice. We set out to compare overnight with 24 hour collection. Twenty-four subjects each collected urine for 24 hours, with the overnight urine being separately collected. The correlation of overnight and 24 hour catecholamines was highest when both measures were standardised for creatinine excretion and when creatinine excretion was adjusted for urine flow rate. The observed correlations were 0.74 for dopamine, 0.81 for noradrenaline and 0.54 for adrenaline. The use of overnight collections may therefore require a sample size up to 1.5 times as large (for noradrenaline) or 3.4 times as large (for adrenaline) to achieve the same power as with 24 hour collections. However, the figures given exaggerate the advantage of 24 hour collections if these incorporate measurement errors that are not present in overnight collections.

  18. Metabolic characteristics of human subcutaneous abdominal adipose tissueafter overnight fast

    PubMed Central

    Humphreys, Sandy M.

    2012-01-01

    Subcutaneous abdominal adipose tissue is one of the largest fat depots and contributes the major proportion of circulating nonesterified fatty acids (NEFA). Little is known about aspects of human adipose tissue metabolism in vivo other than lipolysis. Here we collated data from 331 experiments in 255 healthy volunteers over a 23-year period, in which subcutaneous abdominal adipose tissue metabolism was studied by measurements of arterio-venous differences after an overnight fast. NEFA and glycerol were released in a ratio of 2.7:1, different (P < 0.001) from the value of 3.0 that would indicate no fatty acid re-esterification. Fatty acid re-esterification was 10.2 ± 1.4%. Extraction of triacylglycerol (TG) (fractional extraction 5.7 ± 0.4%) indicated intravascular lipolysis by lipoprotein lipase, and this contributed 21 ± 3% of the glycerol released. Glucose uptake (fractional extraction 2.6 ± 0.3%) was partitioned around 20–25% for provision of glycerol 3-phosphate and 30% into lactate production. There was release of lactate and pyruvate, with extraction of the ketone bodies 3-hydroxybutyrate and acetoacetate, although these were small numerically compared with TG and glucose uptake. NEFA release (expressed per 100 g tissue) correlated inversely with measures of fat mass (e.g., with BMI, rs = −0.24, P < 0.001). We examined within-person variability. Systemic NEFA concentrations, NEFA release, fatty acid re-esterification, and adipose tissue blood flow were all more consistent within than between individuals. This picture of human adipose tissue metabolism in the fasted state should contribute to a greater understanding of adipose tissue physiology and pathophysiology. PMID:22167523

    Glucose metabolism serves as the central source of energy for the human brain. Little is known about the effects of blood glucose level (BGL) on higher-order cognitive functions within a physiological range (e.g., after overnight fasting). In this randomized, placebo-controlled, double blind study, we assessed the impact of overnight fasting (14 h) on brain activation during a working memory task. We sought to mimic BGLs that occur naturally in healthy humans after overnight fasting. After standardized periods of food restriction, 40 (20 male) healthy participants were randomly assigned to receive either glucagon to balance the BGL or placebo (NaCl). A parametric fMRI paradigm, including 2-back and 0-back tasks, was used. Subclinically low BGL following overnight fasting was found to be linked to reduced involvement of the bilateral dorsal midline thalamus and the bilateral basal ganglia, suggesting high sensitivity of those regions to minimal changes in BGLs. Our results indicate that overnight fasting leads to physiologically low levels of glucose, impacting brain activation during working memory tasks even when there are no differences in cognitive performance.

    We examined learning and retention in nonverbal and verbal declarative memory in Hungarian children with (n = 21) and without (n = 21) SLI. Recognition memory was tested both 10 minutes and one day after encoding. On nonverbal items, only the children with SLI improved overnight, with no resulting group differences in performance. In the verbal domain, the children with SLI consistently showed worse performance than the typically-developing children, but the two groups showed similar overnight changes. The findings suggest the possibility of spared or even enhanced declarative memory consolidation in SLI. PMID:28046095

  4. Substance use in rural adolescents: The impact of social capital, anti-social capital, and social capital deprivation.

    2016-01-01

    Middle- and high-school substance use is a pressing public health problem in the United States. Despite similar or, in some cases, elevated rates of substance use among rural youth, much of the extant research on adolescent substance use has focused on urban areas. The current study aims to uncover forms of social capital (e.g., ethnic identity), social capital deprivation (e.g., parent-child conflict), and anti-social capital (e.g., delinquent friends) that impact the use of alcohol, cigarettes, and marijuana in a sample of middle- and high-school students from the rural south. It was hypothesized that social capital factors would be associated with decreased substance use while social capital deprivation and anti-social capital factors would be associated with increased substance use. The hypotheses were tested using logistic regression models with generalized estimating equations. The findings indicated that for middle school youth, anti-social capital in the form of aggression and delinquent friends was significantly associated with an increased likelihood of using alcohol, cigarettes, and marijuana. For high school students, anti-social capital in the form of aggression and delinquent friends and social capital deprivation in the form of neighborhood crime were significantly associated with an increased likelihood of using alcohol, cigarettes, and marijuana. Violent behavior was also significantly associated with an increased likelihood of using marijuana. Females reported less substance use in both middle and high school; reports of use increased with age. Implications are discussed. Given the salience of social capital deprivation, substance use programs should emphasize the skills necessary to avoid or disengage from antisocial relationships.

    Children with chronic heart disease (CHD) are often turned away from recreational summer overnight experiences because of complicated medical histories and medication regimens. The purpose of this qualitative study was to evaluate the psychosocial impact of a five-day overnight recreational experience for children with CHD and their parents. Thirty-six children with CHD between the age of 8 and 15 years and their parents participated in the study. Data were collected from the children using photovoice interviews. Parent data were collected using a post camp survey. Results included the following external outcome themes: inclusion in a peer group and the importance of friendship, fun, and safety. Internal or personal outcome themes included counselor as a role model, increased self-confidence, and the realization of life's possibilities. Parent themes included increased child independence, increased child confidence, and child feelings of normalcy related to belonging to a peer group. Findings from this study can be used to encourage families of children with CHD to allow participation in a well-supervised overnight recreational experience. Such an experience can foster the child's overall development, provide peer group support, and reduce parent anxiety about overnight separation from the child.

    Study Objectives: Patients with postural tachycardia syndrome (POTS) commonly complain of fatigue, unrefreshing sleep, daytime sleepiness, and diminished quality of life. The study objective was to assess objective sleep quality in POTS patients using overnight polysomnography. Methods: We studied 16 patients with POTS and 15 healthy control subjects performing daytime autonomic functions tests and overnight polysomnography at the Vanderbilt Clinical Research Center. Results: There were no significant differences in the objective sleep parameters including sleep efficiency, sleep onset latency, wake time after sleep onset, REM latency, percentage of time spent in N1, N2, N3, and REM sleep, arousal index, apnea-hypopnea index, or periodic leg movement index in POTS patients as compared with healthy control subjects. There were significant negative correlations between sleep efficiency and the change in HR from supine to stand (rs = −0.527; p = 0.036) Conclusions: POTS patients do not have significant differences in objective sleep parameters as compared to control subjects based on overnight polysomnograms. Activation of the sympathetic nervous system may contribute significantly to the hyper arousal state and worsening of subjective estimates of sleep quality as previously reported in POTS patients.

    1996-01-01

    To document the psychophysiological effects of flying overnight cargo operations, 41 B-727 crew members (average age 38 yr) were monitored before, during, and after one of two typical 8-day trip patterns. During daytime layovers, the average sleep episode was 3 hr (41%) shorter than nighttime sleeps and was rated as lighter, less restorative, and poorer overall. Sleep was frequently split into several episodes and totaled 1.2 hr less per 24 hr than on pretrip days. Each trip pattern included a night off, which was an effective countermeasure against the accumulating sleep debt. The organization of sleep during daytime layovers reflected the interaction of duty timing with circadian physiology. The circadian temperature rhythm did not adapt completely to the inverted wake-rest schedule on duty days, being delayed by about 3 hr. Highest subjective fatigue and lowest activation occurred around the time of the temperature minimum. On duty days, reports of headaches increased by 400%, of congested nose by 200%, and of burning eyes by 900%. Crew members also reported eating more snacks. Compared with daytime short-haul air-transport operations, the overnight cargo trips included fewer duty and flight hours, and had longer layovers. Overnight cargo crews also averaged 5.4 yr younger than their daytime short-haul counterparts. On trips, both groups lost a comparable amount of sleep per 24 hr, but the overnight cargo crews had shorter individual sleep episodes and more broken sleep. These data clearly demonstrate that overnight cargo operations, like other night work, involve physiological disruption not found in comparable daytime operations.

    Aggression is a universal social behavior important for the acquisition of food, mates, territory, and social status. Aggression in Drosophila is context-dependent and can thus be expected to involve inputs from multiple sensory modalities. Here, we use mechanical disruption and genetic approaches in Drosophila melanogaster to identify hearing as an important sensory modality in the context of intermale aggressive behavior. We demonstrate that neuronal silencing and targeted knockdown of hearing genes in the fly's auditory organ elicit abnormal aggression. Further, we show that exposure to courtship or aggression song has opposite effects on aggression. Our data define the importance of hearing in the control of Drosophila intermale aggression and open perspectives to decipher how hearing and other sensory modalities are integrated at the neural circuit level.

    In summer 2012, an outbreak of hantavirus infections occurred among overnight visitors to Yosemite National Park in California, USA. An investigation encompassing clinical, epidemiologic, laboratory, and environmental factors identified 10 cases among residents of 3 states. Eight case-patients experienced hantavirus pulmonary syndrome, of whom 5 required intensive care with ventilatory support and 3 died. Staying overnight in a signature tent cabin (9 case-patients) was significantly associated with becoming infected with hantavirus (p<0.001). Rodent nests and tunnels were observed in the foam insulation of the cabin walls. Rodent trapping in the implicated area resulted in high trap success rate (51%), and antibodies reactive to Sin Nombre virus were detected in 10 (14%) of 73 captured deer mice. All signature tent cabins were closed and subsequently dismantled. Continuous public awareness and rodent control and exclusion are key measures in minimizing the risk for hantavirus infection in areas inhabited by deer mice. PMID:24565589

    This investigation explored the generalization of phonetic learning across talkers following training on a nonnative (Hindi dental and retroflex) contrast. Participants were trained in two groups, either in the morning or in the evening. Discrimination and identification performance was assessed in the trained talker and an untrained talker three times over 24 h following training. Results suggest that overnight consolidation promotes generalization across talkers in identification, but not necessarily discrimination, of nonnative speech sounds.

    Skeletal muscle satellite cell (SC) content has been reported to increase following a single bout of exercise. Data on muscle fibre type-specific SC content and/or SC activation status are presently lacking. The objective of the study was to determine the impact of a single bout of exercise on muscle fibre type-specific SC content and activation status following subsequent overnight recovery. Eight healthy men (age, 20 ± 1 years) performed a single bout of combined endurance- and resistance-type exercise. Muscle biopsies were collected before and immediately after exercise, and following 9 h of postexercise, overnight recovery. Muscle fibre type-specific SC and myonuclear content and SC activation status were determined by immunohistochemical analyses. Satellite cell activation status was assessed by immunohistochemical staining for both Delta-like homologue 1 (DLK1) and Ki-67. Muscle fibre size and fibre area per nucleus were greater in type II compared with type I muscle fibres (P < 0.05). At baseline, no differences were observed in the percentage of SCs staining positive for DLK1 and/or Ki67 between fibre types. No significant changes were observed in SC content following 9 h of postexercise, overnight recovery; however, the percentage of DLK1-positive SCs increased significantly during overnight recovery, from 22 ± 5 to 41 ± 5% and from 24 ± 6 to 51 ± 9% in the type I and II muscle fibres, respectively. No changes were observed in the percentage of Ki-67-positive SCs. A single bout of exercise activates both type I and II skeletal muscle fibre SCs within a single night of postexercise recovery, preceding the subsequent increase in SC content.

    Calcium-binding protein B (S100B), a primary product of astrocytes, is a proposed marker of Parkinson's Disease (PD) pathophysiology, diagnosis and progression. However, it has also been implicated in sleep disruption, which is very common in PD. To explore the relationship between S100B, disease severity, sleep symptoms and polysomnography (PSG) findings, overnight changes in serum S100B levels were investigated for the first time in PD. 17 fully treated, non-demented, moderately advanced PD patients underwent PSG and clinical assessment of sleep symptoms. Serum S100B samples were collected immediately before and after the PSG. Results are shown as median [interquartile range]. Night and morning S100B levels were similar, but uncorrelated (rs=-0.277, p=0.28). Morning S100B levels, as opposed to night levels, positively correlated with the Unified Parkinson's Disease rating scale (UPDRS) subsections I and II (rs=0.547, p=0.023; rs=0.542, p=0.025). Compared to those with overnight S100B reduction, patients with overnight S100B elevation had higher H&Y scores (2.5 [0.87] vs. 2 [0.25], p=0.035) and worse total Pittsburgh Sleep Quality Index (PSQI) and Parkinson's Disease Sleep Scores (10 [3.2] vs. 8 [4.5], p=0.037; 92.9 [39] vs. 131.4 [28], p=0.034). Correlation between morning S100B levels and total UPDRS score was strengthened after controlling for total PSQI score (rs=0.531, p=0.034; partial rs=0.699, p=0.004, respectively). Overnight S100B variation and morning S100B were associated with PD severity and perceived sleep disruption. S100B is proposed as a putative biomarker for sleep-related neuroinflammation in PD. Noradrenergic-astrocytic dysfunction is hypothesized as a possible mechanism underlying these findings.

    It has been suggested that liking for the taste, flavour and aroma of, for example, coffee and tea is acquired through the process of classical conditioning, involving association of these orosensory cues with the psychopharmacological consequences of caffeine ingestion. Accordingly, this study investigated caffeine reinforcement by assessing changes in preference for a novel drink consumed with or without caffeine. Particular care was taken to use "ecologically valid" procedures; that is, overnight caffeine abstinence followed by a cup-of-coffee equivalent dose of caffeine (70 mg) at breakfast. Caffeine had no significant effects on drink preference or mood in subjects with habitually low intakes of caffeine. In contrast, moderate users of caffeine developed a relative dislike for the drink lacking caffeine and showed somewhat lowered mood following overnight caffeine abstinence (e.g., less lively, clearheaded and cheerful), which was significantly improved by caffeine. These together with other recent results strongly suggest that, in everyday life, caffeine reinforcement can occur as the result of the alleviation by caffeine of the adverse effects of overnight caffeine abstinence (negative reinforcement). They also demonstrate the utility of this flavour-conditioning procedure, which could be applied in the wider investigation of the reinforcing properties of drugs.

    Study Objective: To determine the effectiveness of continuous positive airway pressure (CPAP) therapy in alleviating known impairments in the overnight consolidation of motor skill learning in patients with obstructive sleep apnea (OSA). Methods: Twenty-five patients with untreated moderate-severe OSA, 13 first-night CPAP users, 17 compliant CPAP users, and 14 healthy control patients were trained on a motor sequence learning task (Sequential Finger Tapping Task, SFTT) and were subsequently tested prior to and after polysomnographic recorded sleep. Measures of subjective sleepiness (Karolinska Sleepiness Scale) and sustained attention (Psychomotor Vigilance Task) were also completed before and after sleep. Results: Typical analyses of overnight improvement on the SFTT show significantly greater overnight gains in motor task speed in controls (+11.6 ± 4.7%, p = 0.007) and compliant CPAP users (+8.9 ± 4.3%, p = 0.008) compared to patients with OSA (−4.86 ± 4.5%). Additional analyses suggest that these improvements in motor performance occurred prior to the sleep episode, as all groups significantly improved (15% to 22%) over a 10-min presleep rest period. Thereafter, performance in all groups significantly deteriorated over sleep (6% to 16%) with trends toward patients with OSA showing greater losses in performance compared to control patients and compliant CPAP users. No between-group differences in subjective sleepiness and sustained attention were found presleep and postsleep. Conclusions: The current data suggest impairments in overnight motor learning in patients with OSA may be a combination of deficient stabilization of memory over a sleep episode as well as increased vulnerability to time on task fatigue effects. Compliant CPAP usage possibly offsets both of these impediments to learning outcomes by improving both sleep quality and subsequent daytime function.

    Background With the advent of sodium glucose co-transporter 2 inhibitors to control glucose and treat diabetes, laboratory data aided by either timed or spot glucose levels in the urine could be used as an alternative marker of drug response. The aim of this study was to assess the agreement between overnight urinary glucose excretion (UGE) and morning spot urinary glucose-to-creatinine ratio (UGCR). Methods In this prospective cross-sectional study, we enrolled a total of 215 participants with either normal glucose tolerance (NGT), pre-diabetes, or type 2 diabetes mellitus (T2DM). To exclude external factors such as food intake and physical activity, urine samples collected overnight at an 8-hr interval and the first-voided morning spot urine were collected and compared. Results The median values of overnight 8-hr UGE in participants with NGT (N=14), pre-diabetes (N=41), and T2DM (N=160) were 35.0 mg, 35.6 mg, and 653.4 mg, respectively. In participants with T2DM, the median values of overnight 8-hr UGCR and first-voided morning spot UGCR (M-UGCR) were 1.37 mg/mg and 0.16 mg/mg, respectively. Quantitative analyses using an intraclass correlation coefficient (ICC) demonstrated a good reliability of measurement of the overnight 8-hr UGCR and M-UGCR (ICC=0.943, P<0.001). The M-UGCR was also significantly related to the overnight 8-hr UGE (r=0.828, P<0.001). Conclusions M-UGCR and overnight 8-hr UGCR showed good agreement, suggesting that M-UGCR be used as a simple index for estimating overnight amounts of UGE in patients with T2DM. PMID:27834060

    In addition to aerobic endurance and anaerobic capacity, high power-to-weight ratio (PWR) is important for cycling performance. Cyclists often try to lose weight before race season to improve body composition and optimize PWR. Research has demonstrated body fat-reducing benefits of exercise after fasting overnight. We hypothesized that fasted-state exercise in calorie-restricted trained cyclists would not result in performance decrements and that their PWR would improve significantly. We also hypothesized that substrate use during fasted-state submaximal endurance cycling would shift to greater reliance on fat. Ten trained, competitive cyclists completed a protocol consisting of baseline testing, 3 weeks of caloric restriction (CR), and post-CR testing. The testing sessions measured pre- and post-CR values for resting metabolic rate (RMR), body composition, VO2, PWR and power-to-lean weight ratio (PLWR), and power output, as well as 2-hour submaximal cycling performance, rating of perceived exertion (RPE), and respiratory exchange ratio (RER). There were no significant differences between baseline and post-CR for submaximal trial RER, power output, VO2, RMR, VO2max, or workload at VO2max. However, RPE was significantly lower, and PWR was significantly higher post-CR, whereas RER did not change. The cyclists' PWR and body composition improved significantly, and their overall weight, fat weight, and body fat percentage decreased. Lean mass was maintained. The cyclists' RPE decreased significantly during 2 hours of submaximal cycling post-CR, and there was no decrement in submaximal or maximal cycling performance after 3 weeks of CR combined with overnight fasting. Caloric restriction (up to 40% for 3 weeks) and exercising after fasting overnight can improve a cyclist's PWR without compromising endurance cycling performance.

    Viewing aggression in its healthy form, in contrast to its extreme and inappropriate versions, and sport as a health-promoting exercise in psychological development and maturation may allow participants and spectators alike to retain an interest in aggression and sport and derive further enjoyment from them. In addition, it will benefit all involved with sport to have a broader understanding of human aggression. Physicians, mental health professionals, and other health care providers can be influential in this process, and should be willing to get involved and speak out when issues and problems arise.

  11. An overnight chill induces a delayed inhibition of photosynthesis at midday in mango (Mangifera indica L.).

    The effect of a cold night on photosynthesis in herbaceous chilling-sensitive crops, like tomato, has been extensively studied and is well characterized. This investigation examined the behaviour of the sub-tropical fruit tree, mango, to enable comparison with these well-studied systems. Unlike tomato, chilling between 5 degrees C and 7 degrees C overnight produced no significant inhibition of light-saturated CO(2) assimilation (A:) during the first hours following rewarming, measured either under controlled environment conditions or in the field. By midday, however, there was a substantial decline in A:, which could not be attributed to photoinhibition of PSII, but rather was associated with an increase in stomatal limitation of A: and lower Rubisco activity. Overnight chilling of tomato can cause severe disruption in the circadian regulation of key photosynthetic enzymes and is considered to be a major factor underlying the dysfunction of photosynthesis in chilling-sensitive herbaceous plants. Examination of the gas exchange of mango leaves maintained under constant conditions for 2 d, demonstrated that large depressions in A: during the subjective night were primarily the result of stomatal closure. Chilling did not disrupt the ability of mango leaves to produce a circadian rhythm in stomatal conductance. Rather, the midday increase in stomatal limitation of A: appeared to be the result of altered guard cell sensitivity to CO(2) following the dark chill.

    Background and objectives Obstructive sleep apnea is associated with significantly increased cardiovascular morbidity and mortality. Fluid overload may promote obstructive sleep apnea in patients with ESRD through an overnight fluid shift from the legs to the neck soft tissues. Body fluid shift and severity of obstructive sleep apnea before and after hemodialysis were compared in patients with ESRD. Design, setting, participants, & measurements Seventeen patients with hemodialysis and moderate to severe obstructive sleep apnea were included. Polysomnographies were performed the night before and after hemodialysis to assess obstructive sleep apnea, and bioimpedance was used to measure fluid overload and leg fluid volume. Results The mean overnight rostral fluid shift was 1.27±0.41 L prehemodialysis; it correlated positively with fluid overload volume (r=0.39; P=0.02) and was significantly lower posthemodialysis (0.78±0.38 L; P<0.001). There was no significant difference in the mean obstructive apnea-hypopnea index before and after hemodialysis (46.8±22.0 versus 42.1±18.6 per hour; P=0.21), but obstructive apnea-hypopnea index was significantly lower posthemodialysis (−10.1±10.8 per hour) in the group of 12 patients, with a concomitant reduction of fluid overload compared with participants without change in fluid overload (obstructive apnea-hypopnea index +8.2±16.1 per hour; P<0.01). A lower fluid overload after hemodialysis was significantly correlated (r=0.49; P=0.04) with a lower obstructive apnea-hypopnea index. Fluid overload—assessed by bioimpedance—was the best predictor of the change in obstructive apnea-hypopnea index observed after hemodialysis (standardized r=−0.68; P=0.01) in multivariate regression analysis. Conclusions Fluid overload influences overnight rostral fluid shift and obstructive sleep apnea severity in patients with ESRD undergoing intermittent hemodialysis. Although no benefit of hemodialysis on obstructive sleep apnea severity

    Porter, M E

    1992-01-01

    The U.S. system of allocating investment capital is failing, putting American companies at a serious disadvantage and threatening the long-term growth of the nation's economy. The problem, says Michael Porter, goes beyond the usual formulation of the issue: accusations of "short-termism" by U.S. managers, ineffective corporate governance by directors, or a high cost of capital. The problem involves the external capital allocation system by which capital is provided to companies, as well as the system by which companies allocate capital internally. America's system is marked by fluid capital and a financial focus. Other countries--notably Japan and Germany--have systems with dedicated capital and a focus on corporate position. In global competition, where investment increasingly determines a company's capacity to upgrade and innovate, the U.S. system does not measure up. These conclusions come out of a two-year research project sponsored by the Harvard Business School and the Council on Competitiveness. Porter recommends five far-reaching reforms to make the U.S. system superior to Japan's and Germany's: 1. Improve the present macroeconomic environment. 2. Expand true ownership throughout the system so that directors, managers, employees, and even customers and suppliers hold positions as owners. 3. Align the goals of capital providers, corporations, directors, managers, employees, customers, suppliers, and society. 4. Improve the information used in decision making. 5. Foster more productive modes of interaction and influence among capital providers, corporations, and business units.

    Several lines of evidence show that the daily amount of melatonin produced differs greatly between individuals. Any polymorphism in the gene of arylalkylamine N-acetyltransferase (AA-NAT), a critical enzyme involved in melatonin biosynthesis, may contribute to the variability of melatonin production. The present study investigated the possible association between overnight melatonin excretion and a commonly occurring -263G/C polymorphism in the promoter region of the human AA-NAT gene. However, we found that -263G/C variant had no effect on the overnight 6-OHMS excretion. In this study, individual genotyping for -263G/C was determined by denaturing high performance liquid chromatography (DHPLC) and confirmed by sequencing. The overnight urinary 6-hydroxymelatonin sulfate (6-OHMS) excretion was quantified by enzyme-linked immunosorbent assay (ELISA).

    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.

    Urinary mutagenicity was evaluated in relation to environmental mutagen exposure (i.e., diet, indoor/outdoor activities, residential area etc.) on the day prior to sample collection, and also considering factors that contribute to the variability of Salmonella mutagenicity assay results. Overnight urine samples from 283 healthy non-smoking residents of northeast Italy (46% males, 20-62 years) were analyzed for mutagenicity on sensitive Salmonella typhimurium strain YG1024 with S9 mix employing the preincubation version of the plate incorporation assay (i.e., the Salmonella reverse mutation test). Urinary mutagenicity varied between 0.02 and 9.84 rev/ equiv. ml, and 7% of samples were positive (i.e., sample elicited a two-fold increase in revertants). There was an evident increase in mutagenicity in subjects with increased intake of mutagen-rich meals (n = 80) (P < 0.01 and positive urine 13% vs. 5%, P = 0.025). Indoor-exposed subjects (n = 65) also showed a higher percentage of positive urine (14% vs. 5%, P = 0.015). In particular, those subjects exposed to cooking fumes the previous evening (n = 28) revealed higher urinary mutagenicity (P = 0.035, positive urine 25% vs. 5%, P < 0.001) than non-indoor exposed. The sources of variability of the mutagenicity assay, mainly the histidine content of the urine concentrate (z = 4.06, P < 0.0001), and to a lesser extent bacterial inoculum size (z = 2.33, P = 0.019), also significantly influenced urinary mutagenicity values. In a linear multiple regression analysis, their effects were still significant (i.e., histidine content P = 0.026 and inoculum size P = 0.021), but the effects of diet, indoor exposure, and other environmental exposures (i.e., traffic and heating system exhausts, residential area) were not. It is concluded that the previous day's exposure to mutagen-rich meals and cooking fumes may influence the presence of mutagenic activity in the overnight urine of non-smoking subjects. This mutagenic activity, which

    Thirty-four flight crew members were monitored before, during, and after two 8-day overnight cargo duty patterns which involved multiple flights at night crossing no more than one time zone per 24 h. Rectal temperature, heart rate, and wrist activity were recorded every 2 min. Sleep quantity and quality, and nap timing, were noted in a logbook. To reduce the masking effects of physical activity on temperature, 0.28 C was added to each subject's raw temperature data whenever he reported being asleep. For both masked and unmasked data, daily temperature minima were estimated from the multiple complex demodulated waveform. The temperature minima did not show a progressive adaptation to night duty, which was interrupted by a night off after 5 nights on one trip pattern and after 3 nights on the other. On duty days, the average temperature minimum delayed by about 3 h, occurring near the end of the duty period. Daytime sleep episodes averaged 2.9 h shorter than nighttime sleep episodes, and were rated as lighter, less restorative, and poorer overall. Fifty-three percent of subjects slept more than once per 24 h while they were on night duty, compared to 17% when able to sleep at night. The total sleep per 24 h on duty days averaged 1.2 h less than pretrip. Twenty-nine percent of subjects lost more than 2 h of sleep per 24 h across the 8-day duty patterns. After night duty, subjects awoke around 1400 local time, even when they had slept 2-3 h less than a normal nocturnal sleep episode. Consequently, the duration of morning sleep episodes was correlated with the off-duty time (multiple r(sup 2)=0.44, F=37.23, p less than 0.0001). Anecdotally, crew members complained of being unable to sleep longer and not feeling well-rested. These wakeups were clustered 6 h after the temperature minimum, which suggests that they may have been a response to the circadian wakeup signal. Daytime layovers in which crew members were able to sleep again in the evening ended later (0200

    Although sleep facilitates learning and memory, the roles of dreaming and habitual levels of recalling dreams remain unknown. This study examined if performance and overnight improvement on a rapid eye movement sleep-sensitive visuomotor task is associated differentially with habitually high or low dream recall frequency. As a relation between dream production and visuospatial skills has been demonstrated previously, one possibility is that frequency of dream recall will be linked to performance on visuomotor tasks such as the Mirror Tracing Task. We expected that habitually low dream recallers would perform more poorly on the Mirror Tracing Task than would high recallers and would show less task improvement following a night of sleep. Fifteen low and 20 high dream recallers slept one night each in the laboratory and performed the Mirror Tracing Task before and after sleep. Low recallers had overall worse baseline performance but a greater evening-to-morning improvement than did high recallers. Greater improvements in completion time in low recallers were associated with Stage 2 rather than rapid eye movement sleep. Findings support the separate notions that dreaming is related to visuomotor processes and that different levels of visuomotor skill engage different sleep- and dream-related consolidation mechanisms.

    The use of lentiviral vectors for the transduction of hematopoietic stem cells has evoked much interest owing to their ability to stably integrate into the genome of nondividing cells. However, published large animal studies have reported highly variable gene transfer rates of typically less than 1%. Here we report the use of lentiviral vectors for the transduction of canine CD34(+) hematopoietic repopulating cells using a very short, 18-hour transduction protocol. We compared lentiviral transduction of hematopoietic repopulating cells from either stem cell factor (SCF)- and granulocyte-colony stimulating factor (G-CSF)-primed marrow or mobilized peripheral blood in a competitive repopulation assay in 3 dogs. All dogs engrafted rapidly within 9 days. Transgene expression was detected in all lineages (B cells, T cells, granulocytes, and red blood cells as well as platelets) indicating multilineage engraftment of transduced cells, with overall long-term marking levels of up to 12%. Gene transfer levels in mobilized peripheral blood cells were slightly higher than in primed marrow cells. In conclusion, we show efficient lentiviral transduction of canine repopulating cells using an overnight transduction protocol. These results have important implications for the design of stem cell gene therapy protocols, especially for those diseases in which the maintenance of stem cells in culture is a major limitation.

  11. Corneal deswelling following overnight wear of rigid and hydrogel contact lenses.

    1988-01-01

    The edema response over a 24-hour sleep/wake cycle of ten subjects wearing a rigid gas-permeable (RGP) lens in one eye and a hydrogel lens in the other was evaluated. Lenses that result in equivalent amounts of overnight edema were selected. There was no significant difference in the rates of deswelling during the initial hour. However, at three and five hours after eye opening, the amount of residual edema was greater in the eye wearing the hydrogel lens. We suggest that when an RGP lens provides the same closed-eye level of oxygen as a hydrogel lens, the greater tear exchange of the RGP lens will result in a greater open-eye oxygen supply, leading to less daytime edema. This suggests that the more complete deswelling we observed with RGP lenses can be attributed to a lower stimulus to open-eye swelling. Biomicroscopy, subjective vision, and patient comfort were also rated on waking and ten hours after eye opening. On eye opening there was significantly more back-surface debris (P = 0.01) with the RGP lenses. Patients wearing RGPs rated comfort as poorer and vision as better but only the latter attained statistical significance.

  12. Room air conditioning by means of overnight cooling of the concrete ceiling

    Active control of the storage mass of an office building in Horgen, Switzerland, by means of a water-carrying pipe system installed in the core of the concrete ceilings has already proven successful over a period of three summers. Comfort measurements in practice and under load-simulated operating conditions have confirmed the suitability of the system for small and medium loads. During the day, only the supply air volume of the mechanical ventilation system is cooled to a temperature of 19 C (66.2 F); the heat stored in the concrete mass is discharged overnight. However, the proportion of cooling water generated in the free-cooling mode remained below expectations. This is attributable to the clearly lower inner thermal loads and the facade insulation, which is no longer up-to-date. Since the building already dispenses a part of its heat via the facade on cooler summer nights, the utilization efficiency of the free concrete core-cooling system diminishes somewhat in importance. The experience gained, however, is recommendation enough for the employment of the embedded pipework system, not only for the cooling but also for the heating of well-insulated buildings with small and medium cooling loads.

    Background Large increases in salivary fluoride were reported 1 h after a calcium pre-rinse/NaF rinse. Aims This study examined the persistence of these increases. Methods 12 subjects rinsed in the evening with water, with a 228 μg/g (ppm) F rinse or with 150 mmol/l calcium lactate followed by a 228 μg/g F rinse. In a second experiment these same patients rinsed with a 912 μg/g F rinse. Saliva samples were obtained the morning after rinsing, centrifuged and the supernatants analyzed. Results The Ca pre-rinse/228 μg/g F rinse induced an increase in overnight salivary F over the 912 μg/g F rinse (≈2.5 times) and a statistically significant increase over the 228 μg/g F rinse (≈5.5 times). Conclusions The results suggest that a Ca pretreatment may increase the cariostatic effect of topical F agents. PMID:18781069

    Drinking water quality is routinely monitored in the distribution network but not inside households at the point of consumption. Fluctuating temperatures, residence times (stagnation), pipe materials and decreasing pipe diameters can promote bacterial growth in buildings. To test the influence of stagnation in households on the bacterial cell concentrations and composition, water was sampled from 10 separate households after overnight stagnation and after flushing the taps. Cell concentrations, measured by flow cytometry, increased (2-3-fold) in all water samples after stagnation. This increase was also observed in adenosine tri-phosphate (ATP) concentrations (2-18-fold) and heterotrophic plate counts (4-580-fold). An observed increase in cell biovolume and ATP-per-cell concentrations furthermore suggests that the increase in cell concentrations was due to microbial growth. After 5 min flushing of the taps, cell concentrations and water temperature decreased to the level generally found in the drinking water network. Denaturing gradient gel electrophoresis also showed a change in the microbial composition after stagnation. This study showed that water stagnation in household pipes results in considerable microbial changes. While hygienic risk was not directly assessed, it emphasizes the need for the development of good material validation methods, recommendations and spot tests for in-house water installations. However, a simple mitigation strategy would be a short flushing of taps prior to use.

  15. Hot rocks or no hot rocks: overnight retreat availability and selection by a diurnal lizard.

    PubMed

    Sabo, John L

    2003-08-01

    I used radio telemetry to determine the effects of substrate size and composition on overnight retreat site selection by western fence lizards (Sceloporus occidentalis). In watersheds of northern California (USA), these lizards occupy two habitat types differing in substrate characteristics: rocky cobble bars found in the dry, active channels of rivers and grassy upland meadows. Rocky substrates, found almost exclusively on cobble bars, provided warmer potential retreat sites than all available retreat sites on meadows during the first 5 h of inactivity. Only cobble and sand substrates provided retreats with temperatures within the preferred daily active range (32-36 degrees C) during the inactive period for these lizards (1900-0900 hours). Females on a cobble bar used rocks as retreats on >90% of nights during the breeding season whereas females on a meadow used wood (>70% of nights) and burrows (>25% of nights). In contrast to females, cobble bar males used rocks significantly less frequently (<70%) and slept in the open air significantly more frequently (25% vs. <1%). Cobble bar females further, showed a significant preference for cobbles 15 cm thick, whereas the rocks used by males did not differ significantly in thickness from those measured in randomly placed transects. Rocks 15 cm thick were the warmest retreats commonly available on this habitat type. Thus, thermal microenvironments available to and chosen by gravid female lizards differ considerably between river and non-river habitats.

    Overnight studies were performed in 10 patients with severe chronic left heart failure (New York Heart Association grades III and IV) without pulmonary disease and in eight controls. Transcutaneous oxygen (Po2) and carbon dioxide tensions (Pco2) and oxygen saturation were measured and the electro-cardiogram was recorded. During sleep mean oxygen saturation fell to 92.7% (minimum 86.1%) from 95.1% when awake. During the night oxygen saturation was below 95% for 62% of the time, below 90% for 6% of the time, and below 85% for 1% of the time. In four patients there were oxygen desaturation dips (a fall of greater than 4% in oxygen saturation from a stable baseline that lasted greater than 30 s) with concurrent increases in Pco2. Two patients had bradycardia during the dips: in one there was non-sustained ventricular tachycardia during the dips and in the other there was ST depression (greater than 0.1 mV at 80 ms after the J point) during a dip. In the controls the fall in mean oxygen saturation from 95.4% when they were awake to 94.4% when they were asleep was less than the fall in patients with heart failure and there were no desaturation dips or arrhythmias. Thus patients with severe heart failure had episodes of oxygen desaturation during sleep, some of which were associated with arrhythmia. Such episodes may be related to the increased risk of sudden death in chronic heart failure. PMID:1907836

    Approximately, 90% of patients with Angelman syndrome present with epileptic seizures. Obtaining an electroencephalogram (EEG) with sleep improves the chances of detecting ictal, interictal, and benign abnormal rhythms in Angelman syndrome. However, electroencephalograms, even when obtained during sleep, can be challenging in this population because of tactile sensitivities as well as anxiety related to a novel environment. We tested the hypothesis that 1 hour of sleep on an electroencephalogram would provide as much information as an entire night of electroencephalogram recording, yet more than a routine electroencephalogram conducted during the day. Overnight polysomnograms were collected in 14 children with Angelman syndrome seen at Vanderbilt University. All patients who obtained sleep within the first hour of the overnight electroencephalogram had interictal discharges recorded. Our results show that when sleep is obtained, a 1-hour electroencephalogram yields just as much information as recording an entire night.

    New sensors for real-time continuous glucose monitoring (CGM) and pumps for continuous subcutaneous insulin infusion (CSII), possibly mounted on the same device, opened new scenarios for Type-1 diabetes treatment. However, possible failures of either CGM or CSII can expose diabetic patients to risks that can be dangerous especially overnight. In this contribution we present a proof-of-concept method, developed in a state-space context and implemented through a Kalman estimator, to detect in real time possible overnight failures of the sensor-pump system by simultaneously using CGM and CSII data. The method is tested on two simulated and one real subject. Results show that the method is able to correctly generate alerts for sensor-pump failures and stimulates further investigation on its development.

    1999-04-01

    This study represents the first systematic investigation of the effects on infant attachment to mother and to father of the increasingly common practice of overnight visitation (time-sharing) with the father in separated and divorced families. There were 145 infants (ages 12 to 20 months) and their mothers (and 83 fathers) who participated in the study. Parents completed questionnaires, were interviewed about their relationship with the baby, and were observed with their infants in the Strange Situation. Infants in separated/divorced families who had regular overnight visits with father (n = 44) were significantly less likely to be classified as secure and more likely to be classified as disorganized or unclassifiable in their attachment to mother than infants in a married comparison group (n = 52). Attachment classification to father was unrelated to visiting (time-sharing) arrangements, but infants were significantly more likely to be classified disorganized/unclassifiable with father in the separated/divorced groups (n = 39) than in dual-parent families (n = 44). Disorganized attachment to mother in the Overnight group was associated with maternal reports of low parent communication and high parent conflict, and with low maternal psychological protection of the infant, assessed from maternal interviews. Consistent with Bowlby's and Rutter's context-sensitive views of the effects of separation, the results suggest that repeated overnight separations from the primary caregiver are associated with disruption in mother-infant attachment when the conditions of visitation are poor, i.e. when parents are unable to provide adequate psychological support to the child.

  2. The nature of human aggression.

    PubMed

    Archer, John

    2009-01-01

    Human aggression is viewed from four explanatory perspectives, derived from the ethological tradition. The first consists of its adaptive value, which can be seen throughout the animal kingdom, involving resource competition and protection of the self and offspring, which has been viewed from a cost-benefit perspective. The second concerns the phylogenetic origin of aggression, which in humans involves brain mechanisms that are associated with anger and inhibition, the emotional expression of anger, and how aggressive actions are manifest. The third concerns the origin of aggression in development and its subsequent modification through experience. An evolutionary approach to development yields conclusions that are contrary to the influential social learning perspective, notably that physical aggression occurs early in life, and its subsequent development is characterized by learned inhibition. The fourth explanation concerns the motivational mechanisms controlling aggression: approached from an evolutionary background, these mechanisms range from the inflexible reflex-like responses to those incorporating rational decision-making.

    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.

    For 416 college students, questioned about their experiences with aggression and television viewing, only very weak correlations between preference for violent shows and aggression were observed.

    Purpose. To investigate the effects of 30 nights of overnight orthokeratology (OOK) on corneal epithelial permeability (Pdc) and corneal biomechanical properties. Methods. BE Retainer and Paragon CRT lenses were used. Visits were scheduled approximately 4 hours after awakening at baseline and after 1, 5, 10, 14, and 30 days of treatment. Pdc was measured at baseline and at day 30, whereas corneal biomechanical properties and visual acuities (VAs) were measured at all visits. Results. Thirty-nine neophytes and soft contact lens wearers completed the study. There was no difference in Pdc between baseline (ln[Pdc] [95% confidence interval (CI)] = −2.65 [−2.80 to −2.50]) and day 30 (ln[Pdc][CI] = −2.68 [−2.85 to −2.50]) (P = 0.88). Corneal hysteresis (CH) and corneal resistance factor (CRF) reduced significantly from baseline (CH [CI] = 10.89 [10.59–11.19] mm Hg and CRF [CI] = 10.35 [9.99–10.72] mm Hg) to day 30 (CH [CI] = 10.59 [10.31–10.87] mm Hg and CRF [CI] = 9.58 [9.26–9.89] mm Hg) (P = 0.001 for CH and P < 0.001 for CRF). Posttreatment VA did not reach baseline targets, and the difference was worse with low-contrast letters. Asian individuals (n = 18) had significantly worse VA than non-Asian individuals (n = 21) under most conditions through day 5, and the difference extended through day 14 with low-contrast letters under mesopic conditions. The percentage of participants who achieved 20/20 uncorrected was 17% Asian and 40% non-Asian individuals after day 1 and reached 69% Asian and 83% non-Asian individuals at day 30. Conclusions. Thirty nights of OOK did not alter Pdc when measured 4 hours after awakening. OOK caused CH and CRF to decrease, but the changes were not clinically significant compared with diseased and postsurgical cases. Asian individuals, who had lower baseline CH in this study, responded slower to OOK based on early uncorrected VA and overrefraction measurements. PMID:23652492

    Study Objectives: Arousal intensity and heart rate (HR) response to arousal during polysomnography (PSG) vary considerably between patients with sleep disorders. Our objective was to determine the range of these arousal characteristics in healthy young adults and whether they are consistent on repeated testing. Design: Post hoc analysis of 56 preexisting PSG files recorded from 28 healthy adults on 2 consecutive nights. Setting: Academic medical center and Research and Development Laboratory (YRT Limited, Winnipeg, Manitoba, Canada). Participants: Twenty-eight healthy young adults. Interventions: None. Measurements and Results: Arousals were identified using an automatic system followed by manual editing. The intensity of arousals was scaled (between 0 and 9) using an automatic algorithm based on the change in the electroencephalography (EEG) signals' wavelet characteristics. 4,751 arousals in 28 pairs of PSGs (night 1 and night 2) were scaled. HR responses (ΔHR) to all arousals were determined and averaged at each arousal scale per file. Overall average arousal intensity ranged 3.0–7.1 in different subjects, and average ΔHR ranged 1.9–18.3 beats.min−1. Heart rate response at a given arousal intensity, expressed as ΔHR at a moderate arousal scale of 5.0 (ΔHR5), ranged 4.1–18.1 beats.min−1. There was a strong correlation between arousal intensity and ΔHR within each subject. More importantly, there were excellent intraclass correlations (ICC) between night 1 and night 2 results for all three variables (ICC = 0.72 for average intensity, 0.92 for average ΔHR4, and 0.91 for ΔHR5). Conclusions: Average arousal intensity and heart rate response to arousal are highly variable among healthy young adults and stable within individuals.

    Background: The Predictive Hypoglycemia Minimizer System (“Hypo Minimizer”), consisting of a zone model predictive controller (the “controller”) and a safety supervision module (the “safety module”), aims to mitigate hypoglycemia by preemptively modulating insulin delivery based on continuous glucose monitor (CGM) measurements. The “aggressiveness factor,” a pivotal variable in the system, governs the speed and magnitude of the controller’s insulin dosing characteristics in response to changes in CGM levels. Methods: Twelve adults with type 1 diabetes were studied in closed-loop in a clinical research center for approximately 24 hours. This analysis focused primarily on the effect of the aggressiveness factor on the automated insulin-delivery characteristics of the controller, and secondarily on the glucose control results. Results: As aggressiveness increased from “conservative” to “medium” to “aggressive,” the controller recommended less insulin (–3.3% vs –14.4% vs –19.5% relative to basal) with a higher frequency (5.3% vs 14.4% vs 20.3%) during the critical times when the CGM was reading 90-120 mg/dl and decreasing. Blood glucose analyses indicated that the most aggressive setting resulted in the most desirable combination of the least time spent <70 mg/dl and the most time spent 70-180 mg/dl, particularly in the overnight period. Hyperglycemia, diabetic ketoacidosis, or severe hypoglycemia did not occur with any of the aggressiveness values. Conclusion: The Hypo Minimizer’s controller took preemptive action to prevent hypoglycemia based on predicted changes in CGM glucose levels. The most aggressive setting was quickest to take action to reduce insulin delivery below basal and achieved the best glucose metrics. PMID:26134834

    2016-02-01

    This selective review provides a model of the neurobiology of impulsive aggression from a cognitive neuroscience perspective. It is argued that prototypical cases of impulsive aggression, those associated with anger, involve the recruitment of the acute threat response system structures; that is, the amygdala, hypothalamus, and periaqueductal gray. It is argued that whether the recruitment of these structures results in impulsive aggression or not reflects the functional roles of ventromedial frontal cortex and dorsomedial frontal and anterior insula cortex in response selection. It is also argued that impulsive aggression may occur because of impaired decision making. The aggression may not be accompanied by anger, but it will reflect disrupted evaluation of the rewards/benefits of the action.

The aggression may not be accompanied by anger, but it will reflect disrupted evaluation of the rewards/benefits of the action. PMID:26465707

  19. False memories for aggressive acts.

    Can people develop false memories for committing aggressive acts? How does this process compare to developing false memories for victimhood? In the current research we used a simple false feedback procedure to implant false memories for committing aggressive acts (causing a black eye or spreading malicious gossip) or for victimhood (receiving a black eye). We then compared these false memories to other subjects' true memories for equivalent events. False aggressive memories were all too easy to implant, particularly in the minds of individuals with a proclivity towards aggression. Once implanted, the false memories were indistinguishable from true memories for the same events, on several dimensions, including emotional content. Implications for aggression-related memory more generally as well as false confessions are discussed.

    The goal of this investigation was to determine whether permissive beliefs about aggression moderate the relation between acute alcohol intoxication and aggression in two large experiments. Participants in Study 1 were 328 (163 men and 165 women) social drinkers and those in Study 2 were 518 (252 men and 266 women) social drinkers. Beliefs about aggression were assessed using a well-validated self-report measure. Following the consumption of either an alcohol or a placebo beverage, participants were tested on a laboratory task in which electric shocks were received from, and administered to, a fictitious opponent under the guise of a competitive reaction-time task. Aggression was operationalized as the combined mean responses for shock intensity and duration across all trials. Our central finding was that alcohol increased aggression in persons with more approving beliefs about aggression than in those who did not hold such beliefs. Our results are discussed within the context of Huesmann's (1988) cognitive script model of aggression. Suggestions for violence prevention efforts are put forth as well.

    Young men with superior upper-body strength typically show a greater proclivity for physical aggression. The traditional interpretation is that young men calibrate their attitudes and behaviors to their physical formidability. Physical strength is thus viewed as a causal antecedent of aggressive behavior. The present study is the first to examine this phenomenon within a developmental framework. We demonstrate that males' antisocial tendencies temporally precede their physical formidability. We capitalize on the fact that physical strength is a male secondary sex characteristic. In two longitudinal cohorts of children, we estimate adolescent change in upper-body strength using the “slope” parameter from a latent growth model. Boys, but not girls, with greater antisocial tendencies in childhood attained larger increases in physical strength between the ages of 11 and 17. These results support sexual selection theory, indicating an adaptive congruence between male-typical behavioral dispositions and subsequent physical masculinization during puberty. PMID:25717041

    This study investigated whether cognitions and emotions elicited by media violence mediate aggressive behavior. Eighty undergraduates, 40 men and 40 women, participated in the experiment. First, subjects were exposed to one of four violent videos which varied in levels of violence and entertainment. Subjects' heart rate and eyeblink rate were continuously recorded while they watched the video. After watching it, subjects described their thoughts which occurred while watching it and rated their affective reactions to it. Finally, their aggressive behavior was measured. Results showed that (1) videos high in violence elicited more aggressive thoughts, more thoughts of negative affect, stronger negative affects, and stronger empty-powerless affects, whereas videos high in entertainment elicited stronger positive affects; (2) no significant differences were found among the videos in terms of physiological reactions and aggressive behavior; and (3) cognitions and emotions elicited by media violence did not mediate aggressive behavior.

    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

    Introduction: Aggressive fibromatosis (AF) is a heterogeneous group of mesenchymal tumors that have locally infiltrative growth and a tendency to relapse. The clinical picture is often conditioned by the obstruction of the ureter or small intestine. Diagnosis is based on clinical, radiological and histological parameters. A case report: We report a case of male patient, aged 35 years, with the retroperitoneal fibromatosis. He reported to the physician because of frequent urination with the feeling of pressure and pain. Computed tomography revealed the tumor mass on the front wall of the bladder with diameter of 70mm with signs of infiltration of the musculature of the anterior abdominal wall. Endoscopic transurethral biopsy showed proliferative lesion binders by type of fibromatosis. The tumor was surgically removed in a classical way. The patient feels well and has no recurrence thirty-six months after the operative procedure. Conclusion: The complete tumor resection is the therapeutic choice for the primary tumor as well as for a relapse. PMID:27147794

  6. From aggressiveness to creativity.

    PubMed

    Mrevlje, Gorazd V

    2004-02-01

    Psychology has a long tradition of considering human creativity as a distinct human characteristic and a special kind of human activity. After explaining the key motives for such an attitude, the author discusses those forms of healthy aggressiveness that stand out as necessary and constitutive elements of the creative process. Taking the well-known statement of C. G. Jung's 'The person who does not build (create), will demolish and destroy' as a starting point, the author compares the basic premises for understanding the process of human creativity, at the same time drawing on Freud's psychology of the individual and Jung's principle of the collective unconscious as well as his notion of 'complexes'. In doing so, the author somewhat boldly paraphrases Jung's dictum: 'In order to be creative, rather than just constructive, one must occasionally also destroy'. With reference to Wallas, Taylor and Neumann (Wallas 1926; Taylor 1959;;Neumann 2001), the author goes on to explore those concepts which help us to investigate the phenomenon of human creativity, drawing distinctions between emergent, expressive, productive, inventive and innovative creativity. The second part of the article discusses the importance of intelligence, originality, nonconformity, subversiveness and free-mindedness for the creative process of human beings. The author concludes with a further explanation of Erich Neumann's argument that human creativity cannot be understood solely as a result of sociogenetic factors, and argues that it is only by taking into consideration Jung's perception of creativity that a global ontological understanding of these processes can be achieved.

  7. More aggressive cartoons are funnier.

    1983-04-01

    Independent rankings of humor and aggressiveness were obtained for sets of cartoons drawn randomly from two different magazines. The correlation of median humor and median aggressiveness rankings ranged from .49 to .90 in six studies involving six different sets of cartoons and six different groups of subjects, including children and adults, high and low socioeconomic status (SES) individuals, and native- and foreign-born individuals. This correlation is consistent with Freudian, arousal, and superiority theories of humor. Another prediction of Freudian theory, that high-SES subjects should be more appreciative of aggressive humor than low-SES subjects, was not supported.

    Consistent with the relative recency of research on workplace aggression and the considerable media attention given to high-profile incidents, numerous myths about the nature of workplace aggression have emerged. In this review, we examine these myths from an evidence-based perspective, bringing greater clarity to our understanding of the predictors of workplace aggression. We conclude by pointing to the need for more research focusing on construct validity and prevention issues as well as for methodologies that minimize the likelihood of mono-method bias and that strengthen the ability to make causal inferences.

    This work aims to define the aggression in all its forms, with notes on management and rapid tranquilization. The pathological aggression is described as a non-homogeneous phenomenon, it is variable in according to social, psychological and biological agents. The distinction of violence between affective aggression and predatory aggression can be functional to the prediction of outcome of any treatment. In general, a pattern of predatory violence tend to match with patients unresponsive and not compliant to treatment, a low probability to predict future violence and, therefore, a difficulty in managing risk. The affective aggressor, however, shows increased probability of treatment response, with more predictability of violent actions in reaction to situations perceived as threatening and, therefore, greater management of future violence risk. Those who act affective violence tend to show a wide range of emotional and cognitive problems, while those who act with predatory patterns show greater inclination to aggression and antisocial behavior. Aggression that occurs in psychiatry mostly appears to be affective, therefore susceptible to modulation through treatments.

    The plasma free amino acid (PFAA) profile is affected by various nutritional conditions, such as the dietary energy balance. Regarding the clinical use of PFAA profiling, it is of concern that differences in food ingestion patterns may generate systematic errors in a plasma amino acid profile and constitute a confounding factor in assessment. In this study, the overnight impact of the dietary energy balance on the postprandial plasma amino acid profile was investigated to elucidate in particular the effects of high protein meals typical in Japanese cuisine. We conducted diet-controlled, crossover trials in eleven healthy male volunteers aged 40-61 y. They consumed either a normal meal (meal N) or high protein meal (meal H) at dinner. Forearm venous blood was collected, and plasma amino acid concentrations were measured before dinner and the next morning. We found that a high protein meal in the evening that contained 40% energy would significantly increase the PFAA concentration the next morning, even more than 12 hours after the meal. Among amino acids, the most significant difference was observed in the branched-chain amino acids (BCAAs) and in some urea-cycle related compounds. If the subject consumed the high protein diet at dinner, the PFAA profile after overnight fasting might be still affected by the meal even 12 hours after the meal, suggesting that the PFAA profile does not reflect the subject's health condition, but rather the acute effect of high protein ingestion.

    Provoked vestibulodynia (PVD) is a highly prevalent and debilitating condition yet its management relies mainly on non-empirically validated interventions. Among the many causes of PVD, there is growing evidence that pelvic floor muscle (PFM) dysfunctions play an important role in its pathophysiology. Multimodal physiotherapy, which addresses these dysfunctions, is judged by experts to be highly effective and is recommended as a first-line treatment. However, the effectiveness of this promising intervention has been evaluated through only two small uncontrolled trials. The proposed bi-center, single-blind, parallel group, randomized controlled trial (RCT) aims to evaluate the efficacy of multimodal physiotherapy and compare it to a frequently used first-line treatment, topical overnight application of lidocaine, in women with PVD. A total of 212 women diagnosed with PVD according to a standardized protocol were eligible for the study and were randomly assigned to either multimodal physiotherapy or lidocaine treatment for 10weeks. The primary outcome measure is pain during intercourse (assessed with a numerical rating scale). Secondary measures include sexual function, pain quality, psychological factors (including pain catastrophizing, anxiety, depression and fear of pain), PFM morphology and function, and patients' global impression of change. Assessments are made at baseline, post-treatment and at the 6-month follow-up. This manuscript presents and discusses the rationale, design and methodology of the first RCT investigating physiotherapy in comparison to a commonly prescribed first-line treatment, overnight topical lidocaine, for women with PVD.

  12. Quantifying Aggressive Behavior in Zebrafish.

    2016-01-01

    Aggression is a complex behavior that influences social relationships and can be seen as adaptive or maladaptive depending on the context and intensity of expression. A model organism suitable for genetic dissection of the underlying neural mechanisms of aggressive behavior is still needed. Zebrafish has already proven to be a powerful vertebrate model organism for the study of normal and pathological brain function. Despite the fact that zebrafish is a gregarious species that forms shoals, when allowed to interact in pairs, both males and females express aggressive behavior and establish dominance hierarchies. Here, we describe two protocols that can be used to quantify aggressive behavior in zebrafish, using two different paradigms: (1) staged fights between real opponents and (2) mirror-elicited fights. We also discuss the methodology for the behavior analysis, the expected results for both paradigms, and the advantages and disadvantages of each paradigm in face of the specific goals of the study.

  13. Vasopressin/oxytocin and aggression.

    PubMed

    Ferris, Craig F

    2005-01-01

    Vasopressin/oxytocin and related peptides comprise a phylogenetically old superfamily of chemical signals in both vertebrates and invertebrates. Each peptide isoform has its own distinct receptor subtype and specific cellular action. The conservation and dispersion of vasopressin/oxytocin signalling systems across the animal kingdom attests to their functional significance in evolution. Indeed, they are involved in the physiology of fluid balance, carbohydrate metabolism, thermoregulation, immunity and reproduction. In addition, these peptides evolved a role in social behaviours related to aggression and affiliation. The focus of this chapter is the role of vasopressin/oxytocin as chemical signals in the brain altering aggressive responding in a context- and species-dependent manner. There is compelling evidence from several mammalian species including humans that vasopressin enhances aggression. The activity of the vasopressin appears linked to the serotonin system providing a mechanism for enhancing and suppressing aggressive behaviour.

    2001-03-01

    The science of ethology is concerned with the way external stimuli and internal events cause animals to fight in a particular way. The classification of dog breeds with respect to their relative danger to humans makes no sense, as both, the complex antecedent conditions in which aggressive behaviour occurs, and its ramifying consequences in the individual dog's ecological and social environment, are not considered. From a biological point of view, environmental and learning effects are always superimposed upon genetic influences. Based on the recent developments in the study of ethology, aggression of wolves (Canis lupus L.) and domesticated dogs (Canis lupus f. familiaris) was put into context with respect to other aspects of the lifestyle of wild and domestic canids. Aggressive behaviour does not occur in a biological vacuum. This is also true for domestic dogs and their relationship to human partners. Individual dogs can become highly aggressive and dangerous. Their development and social situation will be presented and discussed in case studies. Finally, there is the question about defining "normal aggression" versus symptoms for maladaptive aggression resp. danger to humans as conspecifics. It is possible to protect the safety of the public and at the the same time practise animal care. Effective animal control legislation must focus on responsible ownership and socialisation of pups f.e. Problems are not unique to some breeds.

    Objective 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. Method Data were collected using self-administered questionnaires and from a sample of community college students aged 15-25 (N = 1056; 43% male). A structural equation modeling method was used to simultaneously assess the associations between listening to various genres of music, alcohol use, illicit drug use, and aggressive behaviors, taking into account respondents’ age, gender, race/ethnicity, and level of sensation seeking. Results 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. Additionally, alcohol and illicit drug use were positively associated with listening to musical genres of techno and reggae. Control variables such as sensation seeking, age, gender and race/ethnicity were significantly related to substance use and aggressive behaviors. Conclusion 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. Conversely, music listening preference may reflect some personal predispositions or lifestyle preferences. Alternatively, substance use, aggression and music preference are independent constructs, but share common “third factors.” PMID:16608146

    A sample of 98 drivers responded to a Swedish version of the UK Driving Anger Scale [UK DAS; [Lajunen, T., Parker, D., Stradling, S.G., 1998. Dimensions of driver anger, aggressive and highway code violations and their mediation by safety orientation in UK drivers. Transport. Res. Part F 1, 107-121]. The results indicated that the Swedish version, like the British original, measures three sources of driver irritation: "progress impeded", "reckless driving", and "direct hostility". Structural equation modelling was used to investigate the relationships between the three sources of self-reported driver irritation, aggressive actions, speed, sex, age, and annual mileage. The models suggested a positive relationship between the amount of driver irritation and frequency of aggressive actions for all three sources of irritation. Female drivers tended to become more irritated than male drivers, while the male drivers tended to act aggressively more often. Surprisingly, drivers who reported that they enjoy fast speeds did not become more irritated than slower drivers when obstructed. The important conclusions are that experienced irritation often leads to openly aggressively actions, and that expression of aggressive behaviours may be a cause of other drivers' feeling of irritation.

    Gathering information, necessary forms, and financial calculations needed to generate a "capital investment proposal" is an extremely complex and difficult process. The intent of the capital investment proposal is to ensure management that the proposed investment has been thoroughly investigated and will have a positive impact on corporate goals. Meeting this requirement typically takes four or five experts a total of 12 hours to generate a "Capital Package." A Capital Expert System was therefore developed using "Personal Consultant." The completed system is hybrid and as such does not depend solely on rules but incorporates several different software packages that communicate through variables and functions passed from one to another. This paper describes the use of expert system techniques, methodology in building the knowledge base, contexts, LISP functions, data base, and special challenges that had to be overcome to create this system. The Capital Expert System is the successful result of a unique integration of artificial intelligence with business accounting, financial forms generation, and investment proposal expertise.

    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.

    All managed care stakeholders--health plan members, employers, providers, community organizations, and government entitites--share a common interest in reducing healthcare costs while improving the quality of care health plan members receive. Although capitation is a usually thought of primarily as a payment mechanism, it can be a powerful tool providers and health plans can use to accomplish these strategic objectives and others, such as restoring and maintaining the health of plan members or improving a community's health status. For capitation to work effectively as a strategic tool, its use must be tied to a corporate agenda of partnering with stakeholders to achieve broader strategic goals. Health plans and providers must develop a partnership strategy in which each stakeholder has well-defined roles and responsibilities. The capitation structure must reinforce interdependence, shift focus from meeting organizational needs to meeting customer needs, and develop risk-driven care strategies.

    In this paper, we study the fuzzification of Weingartner's pure capital rationing model and its analysis. We develop a primal-dual pair based on t-norm/t-conorm relation for the constraints and objective function for a fully fuzzified pure capital rationing problem except project selection variables. We define the [alpha]-interval under which the weak duality is proved. We perform sensitivity analysis for a change in a budget level or in a cash flow level of a non-basic as well as a basic variable. We analyze the problem based on duality and complementary slackness results. We illustrate the proposed model by computational analysis, and interpret the results.

    Background Partial or total overnight sleep deprivation produces immediate mood improvement in about 50% of patients with depression, but not in healthy controls. Our objectives were to compare the neurochemical changes that accompanied partial overnight sleep deprivation in healthy and depressed participants, and to compare baseline neurochemical profiles and overnight neurochemical changes between those depressed participants who did and did not respond to sleep loss with mood improvement. Methods We studied 2 brain regions (left dorsal prefrontal area and pons) in 12 women with unipolar depression and in 15 healthy women using proton magnetic resonance spectroscopy acquired at 1.5 T. The scans took place at baseline and 24 hours later after a night with sleep restricted to a maximum of 2.5 hours (22:30–01:00). We assessed 3 neurochemical signals (referenced to internal water): N-acetylaspartate (NAA), choline compounds (Cho) and creatine-plus-phosphocreatine (tCr). Results In both groups combined, sleep restriction caused a 20.1% decrease in pontine tCr (F1–16 = 5.07, p = 0.039, Cohen’s d = 0.54) and an 11.3% increase in prefrontal Cho (F1–21 = 5.24, p = 0.033, Cohen’s d = 0.46). Follow-up tests revealed that prefrontal Cho increases were significant only among depressed participants (17.9% increase, t9 = −3.35, p = 0.008, Cohen’s d = 1.06). Five depressed patients showed at least 30% improvement in mood, whereas 6 showed no change or worsening in mood after sleep restriction. Baseline pontine Cho levels distinguished subsequent responders from nonresponders to sleep restriction among depressed participants (z = 2.61, p = 0.008). Limitations A limitation of this study is the relatively small sample size. Conclusion Sleep restriction altered levels of pontine tCr and prefrontal Cho in both groups combined, suggesting effects on phospholipid and creatine metabolism. Baseline levels of pontine Cho were linked to subsequent mood responses to sleep loss

    Aggressiveness criteria proposed in the scientific literature a decade ago provide a quality judgment and are a reference in the care of patients with advanced cancer, but their use is not generalized in the evaluation of Oncology Services. In this paper we analyze the therapeutic aggressiveness, according to standard criteria, in 1.001 patients with advanced cancer who died in our Institution between 2010 and 2013. The results seem to show that aggressiveness at the end of life is present more frequently than experts recommend. About 25% of patients fulfill at least one criterion of aggressiveness. This result could be explained by a liquid Oncology which does not prioritize the patient as a moral subject in the clinical appointment. Medical care is oriented to necessities and must be articulated in a model focused on dignity and communication. Its implementation through Advanced Care Planning, consideration of patient's values and preferences, and Limitation of therapeutic effort are ways to reduce aggressiveness and improve clinical practice at the end of life. We need to encourage synergic and proactive attitudes, adding the best of cancer research with the best clinical care for the benefit of human being, moral subject and main goal of Medicine.

    2016-04-01

    The purpose of this study was to compare whole-body fat oxidation kinetics after prior exercise with overnight fasting in elite endurance athletes. Thirteen highly trained athletes (9 men and 4 women; maximal oxygen uptake: 66 ± 1 mL·min(-1)·kg(-1)) performed 3 identical submaximal incremental tests on a cycle ergometer using a cross-over design. A control test (CON) was performed 3 h after a standardized breakfast, a fasting test (FAST) 12 h after a standardized evening meal, and a postexercise test (EXER) after standardized breakfast, endurance exercise, and 2 h fasting recovery. The test consisted of 3 min each at 30%, 40%, 50%, 60%, 70%, and 80% of maximal oxygen uptake and fat oxidation rates were measured through indirect calorimetry. During CON, maximal fat oxidation rate was 0.51 ± 0.04 g·min(-1) compared with 0.69 ± 0.04 g·min(-1) in FAST (P < 0.01), and 0.89 ± 0.05 g·min(-1) in EXER (P < 0.01). Across all intensities, EXER was significantly higher than FAST and FAST was higher than CON (P < 0.01). Blood insulin levels were lower and free fatty acid and cortisol levels were higher at the start of EXER compared with CON and FAST (P < 0.05). Plasma nuclear magnetic resonance-metabolomics showed similar changes in both EXER and FAST, including increased levels of fatty acids and succinate. In conclusion, prior exercise significantly increases whole-body fat oxidation during submaximal exercise compared with overnight fasting. Already high rates of maximal fat oxidation in elite endurance athletes were increased by approximately 75% after prior exercise and fasting recovery.

    Objective To explore the experiences of adolescents with type 1 diabetes mellitus (T1DM) and their parents taking part in an overnight closed loop study at home, using qualitative and quantitative research methods. Research design and methods Adolescents aged 12–18 years on insulin pump therapy were recruited to a pilot closed loop study in the home setting. Following training on the use of a study insulin pump and continuous glucose monitoring (CGM), participants were randomized to receive either real-time CGM combined with overnight closed loop or real-time CGM alone followed by the alternative treatment for an additional 21 days with a 2–3-week washout period in between study arms. Semistructured interviews were performed to explore participants’ perceptions of the impact of the closed loop technology. At study entry and again at the end of each 21-day crossover arm of the trial, participants completed the Diabetes Technology Questionnaire (DTQ) and Hypoglycemia Fear Survey (HFS; also completed by parents). Results 15 adolescents and 13 parents were interviewed. Key positive themes included reassurance/peace of mind, confidence, ‘time off’ from diabetes demands, safety, and improved diabetes control. Key negative themes included difficulties with calibration, alarms, and size of the devices. DTQ results reflected these findings. HFS scores were mixed. Conclusions Closed loop insulin delivery represents cutting-edge technology in the treatment of T1DM. Results indicate that the psychological and physical benefits of the closed loop system outweighed the practical challenges reported. Further research from longitudinal studies is required to determine the long-term psychosocial benefit of the closed loop technology. PMID:25452866

    Background Patient safety and sleep experts advocate a protected sleep period for residents. Objective We examined whether interns scheduled for a protected sleep period during overnight call would have better end-of-rotation assessments of burnout, depression, and empathy scores compared with interns without protected sleep periods and whether the amount of sleep obtained during on call predicted end-of-rotation assessments. Methods We conducted a randomized, controlled trial with internal medicine interns at the Philadelphia Veterans Affairs Medical Center (PVAMC) and the Hospital of the University of Pennsylvania (HUP) in academic year 2009–2010. Four-week blocks were randomly assigned to either overnight call permitted under the 2003 duty hour standards or a protected sleep period from 12:30 am to 5:30 am. Participants wore wrist actigraphs. At the beginning and end of the rotations, they completed the Beck Depression Inventory (BDI-II), Maslach Burnout Inventory (MBI-HSS), and Interpersonal Reactivity Index (IRI). Results A total of 106 interns participated. There were no significant differences between groups in end-of-rotation BDI-II, MBI-HSS, or IRI scores at either location (P > .05). Amount of sleep while on call significantly predicted lower MBI-Emotional Exhaustion (P < .003), MBI-Depersonalization (P < .003), and IRI-Personal Distress (P < .006) at PVAMC, and higher IRI-Perspective Taking (P < .008) at HUP. Conclusions A protected sleep period produced few consistent improvements in depression, burnout, or empathy, although depression was already low at baseline. Possibly the amount of protected time was too small to affect these emotional states or sleep may not be directly related to these scores. PMID:24949128

    Sentürk, S; Yalçin, E; Pentürk, S

    2003-09-01

    Serum lipids and lipoprotein concentrations have been associated with dominance aggression in humans. The aim of this study was to investigate the link between serum lipids, including cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC) to HDL-C ratio and dominance aggression in dogs. Levels of serum TC, triglyceride and HDL-C were significantly lower in dogs with dominance aggression compared with non-aggressive dogs (P < 0.001). These results suggest that a relationship exists between serum lipid profile and dominance aggression in dogs, and hypocholesterolaemia exists in dogs with dominance aggression.

    Aggressive behavior is widely present throughout the animal kingdom and is crucial to ensure survival and reproduction. Aggressive actions serve to acquire territory, food, or mates and in defense against predators or rivals; while in some species these behaviors are involved in establishing a social hierarchy. Aggression is a complex behavior, influenced by a broad range of genetic and environmental factors. Recent studies in Drosophila provide insight into the genetic basis and control of aggression. The state of the art on aggression in Drosophila and the many opportunities provided by this model organism to unravel the genetic and neurobiological basis of aggression are reviewed. PMID:22513455

  20. Aggressive periodontitis: The unsolved mystery.

    PubMed

    Clark, Danielle; Febbraio, Maria; Levin, Liran

    2017-01-01

    Aggressive periodontal disease is an oral health mystery. Our current understanding of this disease is that specific bacteria invade the oral cavity and the host reacts with an inflammatory response leading to mass destruction of the alveolar bone. Aggressive periodontal disease is typically observed in a population under the age of 30 and occurs so rapidly that it is difficult to treat. Unfortunately, the consequence of this disease frequently involves tooth extractions. As a result, the aftermath is chewing disability and damage to self-esteem due to an altered self-image. Furthermore, patients are encumbered by frequent dental appointments which have an economic impact in regards to both personal financial strain and absent days in the workplace. Aggressive periodontal disease has a tremendous effect on patients' overall quality of life and needs to be investigated more extensively in order to develop methods for earlier definitive diagnosis and effective treatments. One of the mysteries of aggressive periodontal disease is the relatively nominal amount of plaque present on the tooth surface in relation to the large amount of bone loss. There seems to be a hidden factor that lies between the response by the patient's immune system and the bacterial threat that is present. A better mechanistic understanding of this disease is essential to provide meaningful care and better outcomes for patients.

  5. [Slipped capital femoral epiphysis].

    PubMed

    Klein, C; Haraux, E; Leroux, J; Gouron, R

    2017-03-01

    Slipped capital femoral epiphysis (SFCE) is a disorder of the hip, characterized by a displacement of the capital femoral epiphysis from the metaphysic through the femoral growth plate. The epiphysis slips posteriorly and inferiorly. SCFE occurs during puberty and metabolic and epidemiologic risk factors, such as obesity are frequently found. Most chronic slips are diagnosed late. Sagittal hip X-rays show epiphysis slip. In case of untreated SCFE, a slip progression arises with an acute slip risk. Treatment is indicated to prevent slip worsening. The clinical and radiological classification is useful to guide treatment and it is predictive of the prognosis. In situ fixation of stable and moderately displaced SCFE with cannulated screws gives excellent results. Major complications are chondrolysis and osteonecrosis and the major sequelae are femoroacetabular impingement and early arthritis.

  7. Personal standards for judging aggression by a relationship partner: How much aggression is too much?

    PubMed

    Arriaga, Ximena B; Capezza, Nicole M; Daly, Christine A

    2016-01-01

    What determines whether people tolerate partner aggression? This research examined how norms, relationship experiences, and commitment predict personal standards for judging aggressive acts by a partner. Studies 1a and 1b (n = 689) revealed that experiencing aggression in a current relationship and greater commitment predicted greater tolerance for common partner aggression. Study 2 longitudinally tracked individuals who had never experienced partner aggression (n = 52). Once aggression occurred, individuals adopted more tolerant standards, but only if they were highly committed. Study 3 involved experimentally manipulating the relevance of partner aggression among individuals who reported current partner aggression (n = 73); they were more tolerant of aggressive acts imagined to occur by their partner (vs. the same acts by a stranger), but only if they were highly committed. Personal standards for judging partner aggression are dynamic. They shift toward greater tolerance when committed people experience aggression in a current relationship.

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

    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.

  10. Predicting and preventing supervisory workplace aggression.

    PubMed

    Dupré, Kathryne E; Barling, Julian

    2006-01-01

    The authors examined factors that lead to and prevent aggression toward supervisors at work using two samples: doctoral students and correctional service guards. The results supported that perceived interpersonal injustice mediates the relationship between perceptions of supervisory control over work performance and psychological aggression directed at supervisors, and further that psychological aggression toward supervisors is positively associated with physical acts of aggression directed at supervisors, supporting the notion of an escalation of aggressive workplace behaviors. Moreover, employees' perceptions of organizational sanctions (i.e., negative consequences for disobeying organizational policies) against aggression appear to play an important role in the prevention of workplace aggression by moderating the relationship between injustice and aggression targeting supervisors.

  16. Relations of parenting quality, interparental conflict, and overnights with mental health problems of children in divorcing families with high legal conflict.

    PubMed

    Sandler, Irwin N; Wheeler, Lorey A; Braver, Sanford L

    2013-12-01

    The current study examined the associations between child mental health problems and the quality of maternal and paternal parenting, and how these associations were moderated by three contextual factors: quality of parenting by the other parent, interparental conflict, and the number of overnights parents had with the child. Data for the current study came from a sample of divorcing families who are in high legal conflict over developing or maintaining a parenting plan following divorce. Analyses revealed that the associations between child mental health problems and positive maternal and paternal parenting were moderated by the quality of parenting provided by the other parent and by the number of overnights children spent with parents, but not by the level of interparental conflict. When parenting by the other parent and number of overnights were considered together in the same model, only number of overnights moderated the relations between parenting and child-behavior problems. The results support the proposition that the well-being of children in high-conflict divorcing families is better when they spend adequate time with at least one parent who provides high-quality parenting.

  17. Bone resorption is suppressed immediately after the third and fourth days of multiday cycling but persistently increased following overnight recovery.

    PubMed

    2014-01-01

    Previous studies suggest that seasoned cyclists may incur a low bone mineral density. This study investigated the effect of multiday cycling on bone turnover. Ten male cyclists completed 4 consecutive days of cycling for 3 h·day(-1). Sweat calcium excretion during exercise and serum calcium, cortisol, bone formation marker (bone alkaline phosphotase (bone-ALP)), bone resorptive marker (C-terminal telopeptide of type I collagen (β-CTX)), and parathyroid hormone concentration were measured before and immediately postexercise each day. Serum β-CTX concentration increased from pre- to postcycling on days 1 and 2 (p = 0.01) (day 1: 0.31 ± 0.14 to 0.60 ± 0.4 ng·mL(-1); day 2: 0.58 ± 0.26 to 0.87 ± 0.42 ng·mL(-1)), while serum bone-ALP concentration remained unchanged. Conversely, on days 3 and 4 both serum β-CTX (day 3: 0.60 ± 0.26 to 0.43 ± 0.26 ng·mL(-1), p < 0.05; day 4: 0.63 ± 0.21 to 0.43 ± 0.22 ng·mL(-1), p < 0.001) and bone-ALP (p < 0.01) response to exercise was suppressed. Interestingly, calcium lost to sweat and postexercise serum cortisol concentration were also significantly lower on days 3 and 4 than on day 1 (p < 0.05). However, both serum β-CTX (102%-124%) and bone-ALP (25%-29%) remained persistently elevated after 21 h of overnight recovery on all successive days compared with day 1 pre-exercise, where the percentage increase was greater for β-CTX (p < 0.05). Bone resorption, immediately following prolonged cycling, is acutely reduced by the third and fourth consecutive days and is coincident to reduced sweat calcium excretion and cortisol concentration. However, multiday cycling imposes a persistent increase in bone resorption following overnight recovery.

    Background Appropriate oral hygiene is required to maintain oral health in denture wearers. This study aims to compare the role of denture cleaning methods in combination with overnight storage conditions on biofilm mass and composition on acrylic removable dentures. Methods In a cross-over randomized controlled trial in 13 older people, 4 conditions with 2 different mechanical cleaning methods and 2 overnight storage conditions were considered: (i) brushing and immersion in water without a cleansing tablet, (ii) brushing and immersion in water with a cleansing tablet, (iii) ultrasonic cleaning and immersion in water without a cleansing tablet, and (iv) ultrasonic cleaning and immersion in water with a cleansing tablet. Each test condition was performed for 5 consecutive days, preceded by a 2-days wash-out period. Biofilm samples were taken at baseline (control) and at the end of each test period from a standardized region. Total and individual levels of selected oral bacteria (n = 20), and of Candida albicans were identified using the Polymerase Chain Reaction (PCR) technique. Denture biofilm coverage was scored using an analogue denture plaque score. Paired t-tests and Wilcoxon-signed rank tests were used to compare the test conditions. The level of significance was set at α< 5%. Results Overnight denture storage in water with a cleansing tablet significantly reduced the total bacterial count (p<0.01). The difference in total bacterial level between the two mechanical cleaning methods was not statistically significant. No significant effect was observed on the amount of Candida albicans nor on the analogue plaque scores. Conclusions The use of cleansing tablets during overnight denture storage in addition to mechanical denture cleaning did not affect Candida albicans count, but reduced the total bacterial count on acrylic removable dentures compared to overnight storage in water. This effect was more pronounced when combined with ultrasonic cleaning compared to

    2013-01-01

    Although there have been hundreds of studies on media violence, few have focused on literature, with none examining novels. Accordingly, the aim of the current study was to examine whether reading physical and relational aggression in books was associated with aggressive behavior in adolescents. Participants consisted of 223 adolescents who completed a variety of measures detailing their media use and aggressive behavior. A non-recursive structural equation model revealed that reading aggression in books was positively associated with aggressive behavior, even after controlling for exposure to aggression in other forms of media. Associations were only found for congruent forms of aggression. Implications regarding books as a form of media are discussed.

  5. Effects of overnight captivity on antioxidant capacity and clinical chemistry of wild southern hairy-nosed wombats (Lasiorhinus latifrons).

    PubMed

    2014-09-01

    An animal's antioxidant capacity is measured by its ability to quench reactive oxygen species (ROS). During everyday metabolism, antioxidants and ROS are in equilibrium with one another. In times of stress, an animal produces more ROS and therefore uses its antioxidant capacity more readily in order to maintain this equilibrium. When the production of ROS exceeds the antioxidant capacity, an animal will experience extensive oxidative stress, which can ultimately affect that animal's health. During experimental study of wild animals, it is often necessary to capture them for a short period of time. In order to obtain a measurement of the effects of short-term captivity on oxidative capacity in wild animals, a population of southern hairy-nosed wombats (Lasiorhinus latifrons) in Swan Reach, South Australia (34.57 degrees S, 139.60 degrees E), was studied. To assess the variation in antioxidant capacity, two assays, the ferric reducing ability of plasma and the trolox equivalent antioxidant capacity, were performed. A third assay, thiobarbituric acid reactive substances, was used to measure the effects of ROS. Measurements of the specific antioxidants uric acid, ascorbic acid, retinol, alpha-tocopherol, and superoxide dismutase were also performed. The biochemical parameters albumin, total protein, cholinesterase, creatinine, and urea were measured as indicators for health. Results showed a significant reduction in antioxidant capacity during the overnight period of captivity.

    Previous studies suggest that sleep-specific brain activity patterns such as sleep spindles and electroencephalographic slow-wave activity contribute to the consolidation of novel memories. The generation of both sleep spindles and slow-wave activity relies on synchronized oscillations in a thalamo-cortical network that might be implicated in synaptic strengthening (spindles) and downscaling (slow-wave activity) during sleep. This study further examined the association between electroencephalographic power during non-rapid eye movement sleep in the spindle (sigma, 12-16 Hz) and slow-wave frequency range (0.1-3.5 Hz) and overnight memory consolidation in 20 healthy subjects (10 men, 27.1 ± 4.6 years). We found that both electroencephalographic sigma power and slow-wave activity were positively correlated with the pre-post-sleep consolidation of declarative (word list) and procedural (mirror-tracing) memories. These results, although only correlative in nature, are consistent with the view that processes of synaptic strengthening (sleep spindles) and synaptic downscaling (slow-wave activity) might act in concert to promote synaptic plasticity and the consolidation of both declarative and procedural memories during sleep.

  7. Social capital and psychological distress.

    PubMed

    Song, Lijun

    2011-12-01

    The author proposes a conceptual model to explain the diverse roles of social capital--resources embedded in social networks--in the social production of health. Using a unique national U.S. sample, the author estimated a path analysis model to examine the direct and indirect effects of social capital on psychological distress and its intervening effects on the relationships between other structural antecedents and psychological distress. The results show that social capital is inversely associated with psychological distress, and part of that effect is indirect through subjective social status. Social capital also acts as an intervening mechanism to link seven social factors (age, gender, race-ethnicity, education, occupational prestige, annual family income, and voluntary participation) with psychological distress. This study develops the theory of social capital as network resources and demonstrates the complex functions of social capital as a distinct social determinant of health.

  8. Orthodontic Management in Aggressive Periodontitis.

    2017-01-01

    Aggressive periodontitis is a type of periodontitis with early onset and rapid progression and mostly affecting young adults who occupy a large percentage of orthodontic patients. The role of the orthodontist is important in screening the disease, making a provisional diagnosis, and referring it to a periodontist for immediate treatment. The orthodontist should be aware of the disease not only before starting the appliance therapy, but also during and after the active mechanotherapy. The orthodontic treatment plan, biomechanics, and appliance system may need to be modified to deal with the teeth having reduced periodontal support. With proper force application and oral hygiene maintenance, orthodontic tooth movement is possible without any deleterious effect in the tooth with reduced bone support. With proper motivation and interdisciplinary approach, orthodontic treatment is possible in patients with controlled aggressive periodontitis.

    The June 2005 Clinical Journal of Oncology Nursing editorial titled "Communication: Whose Problem Is It?" (Griffin-Sobel, 2005) was written to begin a dialogue about a phenomenon frequently experienced yet rarely discussed: workplace aggression, also known as disruptive behavior. Prompted by a groundbreaking study published in the American Journal of Nursing by Rosenstein and O'Daniel (2005), the editorial challenged oncology nurses to begin to fix problems of communication. After reflecting on both of the articles and considering my own experience as a nurse manager, clinician, and scholar, I decided to explore the topic as it relates to nurse-to-nurse workplace aggression. The following is a summary of interviews with nurse managers, nurse practitioners, and nurse scientists about root causes and effective strategies to manage these sometimes complicated situations. This article is meant to continue the dialogue about the very sensitive issue. Confidentiality has been maintained, and I welcome your comments.

    In analysis of the results of treatment of 48 episodes of spontaneous pneumothorax, aggressive treatment by means of closed intercostal drainage with constant suction was found to achieve the aims of therapy more effectively than conservative measures of bed rest with or without needle aspiration. In general, full expansion of the lung was more quickly restored, recurrence was of lesser incidence, the period in hospital was shorter and the time away from work was reduced. ImagesFigure 1.

    Structural equation modeling with latent variables was used to evaluate the direct and mediated effects of a neighborhood risk factor (negative teen behaviors) on the parent-report aggressive behavior of 213 students in grades 3 through 5 attending a school in a low-income, rural community. Contagion and social control hypotheses were examined as well as hypotheses about whether the neighborhood served as a microsystem or exosystem for rural pre-adolescents. Analyses took into account the clustering of students and ordinal nature of the data. Findings suggest that rural neighborhoods may operate as both a microsystem and exosystem for children, with direct contagion effects on their aggressive behaviors as well as indirect social control effects through parenting practices. Direct effects on aggression were also found for parenting practices and child reports of friends' negative behaviors. Pre-adolescence may be a transitional stage, when influences of the neighborhood on child behavior begin to compete with influences of caregivers. Findings can inform the timing and targets of violence prevention in rural communities.

    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.

    The purpose of this study was to examine the acute effects of alcohol on aggressive behavior in men and women in a laboratory setting. Participants were 526 (261 men and 265 women) healthy social drinkers between 21 and 35 years of age. They were randomly assigned to either an alcohol or a placebo group. Aggression was measured using a modified version of the Taylor Aggression Paradigm in which electric shocks are received from, and delivered to, a same gender fictitious opponent during a supposed competitive interpersonal task. Aggression was operationalized as the intensity and duration of shocks that participants administered to their "opponent." Overall, men were more aggressive than women. Alcohol increased aggression for both men and women but this effect was stronger for men. This is one of the first laboratory studies to demonstrate that alcohol increases aggression in women.

    In the treatment of violent-aggressive behavior, four major groups of drugs emerged: 1. Major tranquilizers in the treatment of aggressive-violent behavior associated with psychotic syndromes. 2. Anti-epileptic drugs such as diphenylhydantoin and barbiturates in the treatment of aggressive-violent behavior within the epileptic syndrome. 3. Psychostimulants in the treatment of aggressive behavior of adolescents and children within behavior disturbances. 4. Anti-male hormones such as cyproterone acetate in the treatment of violent-aggressive behavior associated with pathological sexual hyperactivity. Whereas each category of drug is predominantly effective in one type of aggressive syndrome, it may also be effective in other conditions as well. Aggression as a result of a personality disorder is most difficult to treat with drugs.

    Children who grow up in aggressive households are at risk of having problems with physiological regulation, but researchers have not investigated physiology as a mechanism in the intergenerational transmission of aggression. In this article, we posit that physiological regulation, particularly during stressful interpersonal interactions, may shed light on sensitivity to conflict, It can also inform our understanding of associations between childhood exposure to aggression in families of origin and aggression against partners in adolescence or adulthood. In support of this model, we highlight findings showing that childhood exposure to family aggression relates to physiological regulation across the life span, and that reactions to physiological stress concurrently relate to aggression against intimate partners. Emerging evidence from research on biological processes during stressful interpersonal interactions raises questions about what is adaptive for individuals from aggressive families, particularly as past family experiences intersect with the challenges of new relationships.

    Pigs in modern farming practice may be exposed to a number of stressors, including social stressors such as mixing or isolation. This may potentially affect both cognitive abilities and stress physiology of the animals. We tested the hypothesis that overnight social isolation in pigs impairs performance in a cognitive holeboard (HB) task (Experiment 1) and the Pig Gambling Task (PGT) (Experiment 2), a decision-making task inspired by the Iowa Gambling Task. In addition, we tested the effect of overnight social isolation on salivary cortisol levels. A within-subjects approach was used in which performance in the two behavioral tasks and cortisol levels were first determined during normal social housing, followed by performance and cortisol levels after experiencing stress induced by overnight social isolation. A total of 19 female pigs with a birth weight closest to their respective litter average was selected from 10 different litters and placed in two pens after weaning. Following habituation, pigs were trained in the HB task, starting at 10 weeks of age. Then, the pigs were isolated overnight, five individuals per night, at 15, 16, and 17 weeks of age. Between these three isolations, social housing and training in the HB continued. Starting 6 weeks after the end of the HB experiment, at approximately 23 weeks of age, the pigs were trained in the PGT. The effects of overnight social isolation on performance in this task were assessed once, when the pigs were 25 weeks old. Salivary cortisol was measured from samples collected 15 min after the start of isolation and at the end of the isolation period and compared to baseline values collected before the start of social isolation. Our results did not confirm the hypothesis that isolation impaired HB performance and decision-making in the PGT. Unexpectedly, overnight social isolation decreased cortisol levels below baseline values, an effect that was not associated with changes in performance of the

    Research into the relationship between alcohol and aggression has previously focused on men. However, in recent years there has been an increase in binge drinking and violent crime among women, behaviours which have been labelled 'ladette' culture in the UK. The current study advances the literature in this area by investigating the relationship between alcohol consumption and aggressive behaviour of females in licensed premises, including the type of aggression and motivations for aggressive incidents. Ninety-three female university students completed the Student Alcohol Questionnaire (SAQ; Engs, 2002), the Aggression Questionnaire (Buss & Perry, 1992) and a questionnaire developed to measure self-reported aggressive incidents. Females who had been involved in an aggressive incident reported spending more time on average in licensed premises per week and higher levels of aggression as well as consuming significantly more alcohol on the day of the incident than females who had not been involved in an aggressive incident. Contrary to expectations, however, those who had been involved in an aggressive incident did not report drinking more beer (a male-orientated drink) than those who had not. Verbally aggressive incidents were reported more than physically aggressive incidents, and aggression was commonly motivated by an emotional reaction or to address a grievance. The finding that average alcohol consumption per week was significantly associated with female aggression in licensed premises highlights the importance of developing interventions to reduce alcohol consumption among young females.

    Using a recently created preemptive strike game (PSG) with 176 participants, we investigated if the motivations of spite and/or fear promotes aggression that requires a small cost to the aggressor and imposes a larger cost on the opponent, and confirmed the earlier finding that fear does but spite does not promote intergroup aggression when the groups are characterized as minimal groups; additionally, the rate of intergroup aggression did not vary according to the group membership of the opponent. The PSG represents a situation in which both the motivations of spite and of fear can logically drive players to choose an option of aggression against an opponent. Participants decide whether or not to attack another participant, who also has the same capability. The decision is made in real time, using a computer. We discuss theoretical implications of our findings on the evolutionary foundations of intragroup cooperation and intergroup aggression. The evolutionary model of intergroup aggression, or the parochial altruism model, posits that intragroup cooperation and intergroup aggression have co-evolved, and thus it predicts both intragroup cooperation and intergroup aggression to emerge even in a minimal group devoid of a history of intergroup relationships. The finding that only intragroup cooperation but not intergroup aggression emerged in the minimal group experiments strongly suggests that intergroup aggression involves a psychological mechanism that is independent from that of intragroup cooperation. We further discuss the implications of these findings on real-world politics and military strategy. PMID:28174553

    The prevalence of behaviour problems is reported from a questionnaire study among members of the Danish Kennel Club (DKC). In total, 4359 dog owners were included in the analyses. With logistic regression, we analysed four behaviour problems: dominance towards the owner, interdog dominance aggression, separation anxiety and shooting phobia. Compared to Labrador Retrievers, the following breeds and breed groups had higher odds of being reported to have interdog dominance aggression: Belgian Sheepdogs, Dachshunds, Dalmatians, German Shepherds, Hovawarts, Pinschers, Rottweilers, Scent dogs and Spitz dogs. Poodles, retrieving/flushing dogs, Sheepdogs, Spitz dogs and terriers had higher odds of shooting phobia. The odds of interdog dominance aggression were higher among dogs owned by younger dog owners compared to dogs owned by older dog owners. Dogs living in the capital area of Copenhagen had increased odds of interdog dominance aggression as compared to dogs living in other parts of Denmark. Dogs belonging to owners with limited knowledge of the breed before acquiring the dog had higher odds of interdog dominance aggression. Dogs attending obedience training classes had reduced odds of shooting phobia. Dogs belonging to dog breeders had reduced odds of being reported to have the investigated behaviour problems.

    Large organizations, including the US Army Medical Department and the Army Nurse Corps, are people-based organizations. Consequently, effective and efficient management of the human capital within these organizations is a strategic goal for the leadership. Over time, the Department of Defense has used many different systems and strategies to manage people throughout their service life-cycle. The current system in use is called Human Capital Management. In the near future, the Army's human capital will be managed based on skills, knowledge, and behaviors through various measurement tools. This article elaborates the human capital management strategy within the Army Nurse Corps, which identifies, develops, and implements key talent management strategies under the umbrella of the Corps' human capital goals. The talent management strategy solutions are aligned under the Nurse Corps business strategy captured by the 2008 Army Nurse Corps Campaign Plan, and are implemented within the context of the culture and core values of the organization.

  7. Measuring social capital: further insights.

    PubMed

    Carrillo Álvarez, Elena; Riera Romaní, Jordi

    Social capital is defined as the resources available to individuals and groups through membership in social networks. However, multiple definitions, distinct dimensions and subtypes of social capital have been used to investigate and theorise about its relationship to health on different scales, creating a confusing picture. This heterogeneity makes it necessary to systematise social capital measures in order to build a stronger foundation in terms of how these associations between the different aspects of social capital and each specific health indicator develop. We aim to provide an overview of the measurement approaches used to measure social capital in its different dimensions and scales, as well as the mechanisms through which it is presumed to influence health. Understanding the mechanisms through which these relationships develop may help to refine the existing measures or to identify new, more appropriate ones.

    2011-06-01

    In the Canadian Animal Genetic Resource Program, bull semen is donated in frozen or fresh (diluted) states. This study was designed to assess the cryopreservation of diluted bull semen shipped at 4°C overnight, and to determine the post-thaw quality of shipped semen using different straw volumes and freezing rates. Semen was collected from four breeding bulls (three ejaculates per bull). Semen was diluted in Tris-citric acid-egg yolk-glycerol (TEYG) extender, cooled to 4°C and frozen as per routine (control semen). After cooling to 4°C, a part of semen was removed and shipped overnight to the research laboratory via express courier (shipped semen). Semen was packaged in 0.25 or 0.5 ml straws and frozen in a programmable freezer using three freezing rates, i.e., -10, -25 or -40°C/min. Control semen was also shipped to the research laboratory. Post-thaw sperm motility characteristics were assessed using CASA, and post-thaw sperm plasma membrane, mitochondrial membrane potential and normal acrosomes were assessed using flow cytometry. Post-thaw sperm quality was greater in shipped semen as compared to control (P<0.001). The shipped semen packaged in 0.25 ml straws had better post-thaw sperm quality than in 0.5 ml straws (P<0.001). Freezing rate had no effect on post-thaw sperm quality. In conclusion, bull semen can be shipped overnight for subsequent cryopreservation and gene banking. Overnight shipping of semen was found advantageous for bull semen cryopreservation. Semen packaging in 0.25 ml straws yielded better post-thaw quality than 0.5 ml straws.

  14. Sleep deprivation suppresses aggression in Drosophila

    2015-01-01

    Sleep disturbances negatively impact numerous functions and have been linked to aggression and violence. However, a clear effect of sleep deprivation on aggressive behaviors remains unclear. We find that acute sleep deprivation profoundly suppresses aggressive behaviors in the fruit fly, while other social behaviors are unaffected. This suppression is recovered following post-deprivation sleep rebound, and occurs regardless of the approach to achieve sleep loss. Genetic and pharmacologic approaches suggest octopamine signaling transmits changes in aggression upon sleep deprivation, and reduced aggression places sleep-deprived flies at a competitive disadvantage for obtaining a reproductive partner. These findings demonstrate an interaction between two phylogenetically conserved behaviors, and suggest that previous sleep experiences strongly modulate aggression with consequences for reproductive fitness.

    2004-11-01

    The primary goal of this investigation was to determine whether executive functioning (EF) would moderate the alcohol-aggression relation. Participants were 310 (152 men and 158 women) healthy social drinkers between 21 and 35 years of age. EF as well as non-EF skills were measured with 13 validated neuropsychological tests. Following the consumption of either an alcoholic or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm (S. Taylor, 1967), in which mild electric shocks were received from, and administered to, a fictitious opponent. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent. EF was negatively related to aggressive behavior for men, regardless of beverage group, even when controlling for non-EF skills. Furthermore, alcohol increased aggression only for men with lower EF scores. Finally, the mere belief that alcohol was consumed suppressed aggression for women but not for men.

    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.

Daily averaged blood glucose levels were highly correlated with Hb A(1c), as determined with a hand-held automated device using an immunodetection method. R(2) values were 0.90, 0.95, and 0.99 in KK/HIJ, C57BL/6J, and DBA/2J, respectively. Six-hour fasting blood glucose correlated more closely with the level of daily averaged blood glucose and with Hb A(1c) than did blood glucose following an overnight fast. To validate the immunoassay-determined Hb A(1c), we also measured total glycosylated hemoglobin using boronate HPLC. Hb A(1c) values correlated well with total glycosylated hemoglobin in all three strains but were relatively lower than total glycosylated hemoglobin in diabetic DBA/2J mice. These results show that 6-h fasting glucose provides a superior index of glycemic control and correlates more closely with Hb A(1c) than overnight-fasted blood glucose in these strains of mice.

    The purpose of the present study was to ascertain whether children beginning martial arts training were more aggressive than their peers. 150 8-yr.-old children were administered the Buss-Perry Aggression Questionnaire. Analysis showed that children beginning martial arts training did not score more aggressive than their peers but scored higher on the Anger scale. This difference, however, appeared only in children practicing judo.

  1. Genetics of human aggressive behaviour.

    Craig, Ian W; Halton, Kelly E

    2009-07-01

    A consideration of the evolutionary, physiological and anthropological aspects of aggression suggests that individual differences in such behaviour will have important genetic as well as environmental underpinning. Surveys of the likely pathways controlling the physiological and neuronal processes involved highlight, as obvious targets to investigate, genes implicated in sexual differentiation, anxiety, stress response and the serotonin neurotransmitter pathway. To date, however, association studies on single candidates have provided little evidence for any such loci with a major effect size. This may be because genes do not operate independently, but function against a background in which other genetic and environmental factors are crucial. Indeed, a series of recent studies, particularly concentrating on the serotonin and norepinephrine metabolising enzyme, monoamine oxidase A, has emphasised the necessity of examining gene by environmental interactions if the contributions of individual loci are to be understood. These findings will have major significance for the interpretation and analysis of data from detailed whole genome association studies. Functional imaging studies of genetic variants affecting serotonin pathways have also provided valuable insights into potential links between genes, brain and aggressive behaviour.

  2. Aggressive lymphoma in the elderly.

    2000-02-01

    Persons 65 years of age and older are the fastest growing segment of the United States population. Over the next 30 years they will comprise approximately 20% of the population. There will be a parallel rise in the number of patients with non-Hodgkin's lymphoma. Age has long been known to be an adverse prognostic factor. Clinical trials of older patients are complicated by the effect of comorbid illness, particularly its effect on overall survival. CHOP (cyclophosphamide, Adriamycin, vincristine, prednisone) remains the standard therapy for all patients with aggressive non-Hodgkin's lymphoma. There are a number of regimens which may be beneficial for older patients with significant comorbidity and poor performance status. The randomized trials in the elderly has reaffirmed CHOP and emphasize the need for adequate dosing, maintaining schedule and anthracyclines. Relapsed patients have a poor prognosis but selected fit older patients may benefit from aggressive reinduction regimens and possibly bone marrow transplantation. Future research should include defining the role of comorbidity, measurement of organ dysfunction and assessment of performance status with geriatric functional scales. New drug treatments should also be explored.

    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.

  4. Aggression and coexistence in female caribou

    2014-01-01

    Female caribou (Rangifer tarandus) are highly gregarious, yet there has been little study of the behavioral mechanisms that foster coexistence. Quantifying patterns of aggression between male and female, particularly in the only cervid taxa where both sexes grow antlers, should provide insight into these mechanisms. We asked if patterns of aggression by male and female caribou followed the pattern typically noted in other polygynous cervids, in which males display higher frequencies and intensity of aggression. From June to August in 2011 and 2012, we measured the frequency and intensity of aggression across a range of group sizes through focal animal sampling of 170 caribou (64 males and 106 females) on Adak Island in the Aleutian Archipelago, Alaska. Males in same-sex and mixed-sex groups and females in mixed-sex groups had higher frequencies of aggression than females in same-sex groups. Group size did not influence frequency of aggression. Males displayed more intense aggression than females. Frequent aggression in mixed-sex groups probably reflects lower tolerance of males for animals in close proximity. Female caribou were less aggressive and more gregarious than males, as in other polygynous cervid species.

    2014-10-01

    Using conservation of resources theory, we examined the relationship between intimate partner aggression enacted against heterosexual women and 3 types of work-related outcomes for these women: withdrawal while at work (i.e., cognitive distraction, work neglect), withdrawal from work (i.e., partial absenteeism, intentions to quit), and performance. In Study 1, we compared withdrawal both at and from work across 3 clinically categorized groups of women (n = 50), showing that experiencing physical aggression is related to higher work neglect. We replicated and extended these findings in Study 2 using a community sample of employed women (n = 249) by considering the incremental variance explained by both physical aggression and psychological aggression on these same outcomes. Results showed that physical aggression predicted higher levels of withdrawal both at and from work, with psychological aggression predicting additional variance in partial absenteeism over and above the effects of physical aggression. Study 3 extended the model to include academic performance as an outcome in a sample of female college students (n = 122) in dating relationships. Controlling for the women's conscientiousness, psychological aggression predicted lower academic performance after accounting for the effects of physical aggression. We discuss theoretical and practical implications of these results, as well as directions for future research.

    2015-05-01

    The present study enriches our knowledge on the relationship between security personnel and situational cues that may provoke aggression, such as arms and uniforms. The study examined 259 security personnel who completed an aggression questionnaire (AGQ). The study aimed (a) to compare the tendency toward aggression of security personnel who carry or do not carry arms and/or wear a uniform and (b) to compare the tendency toward aggression of men and women security personnel who carry or do not carry arms and/or wear a uniform. The findings indicated no main effect for aggression cueing classification. However, uniformed men had higher scores of physical aggression than women, and women scored significantly higher on anger than men when not carrying any aggressive cues. The findings also revealed that in general, men security personnel reported much higher physical aggression than women, while women showed slightly higher means of verbal aggression than men. The findings are discussed in light of the gender theory and research.

    The present study examined the longitudinal course of men’s physical and psychological aggression toward a partner across 10 years, using a community sample of young couples (N = 194) from at-risk backgrounds. Findings indicated that men’s aggression decreased over time and that women’s antisocial behavior and depressive symptoms predicted changes in men’s aggression. This suggests the importance of studying social processes within the dyad to have a better understanding of men’s aggression toward a partner. PMID:19122790

    PubMed

    Ohbuchi, K

    1987-06-01

    In this review, the author theoretically and empirically examined motives and interpersonal functions of aggression. A factor-analysis of Averill's questionnaire items on anger revealed that motives involved in aggressive responses were clustered into two groups: the hostile and the instrumental. It was also clarified that an individual is likely to engage in aggression particularly when some hostile motives are evoked. Concerning the interpersonal functions, the author proposed that aggression might serve four principal goals. (1) Aggression can be generated as an avoidance response to an aversive stimulus, such as frustration, annoyance, or pain, and so on. It depends on the severity of the stimulus. It was however emphasized that aggression is also mediated by social cognition, such as an attribution of intent to a harm-doer. (2) Aggression can be used as a means of coercing the other person into doing something. An individual is likely to use such a power strategy if he/she is lacking in self-confidence or a perspective for influencing the target person by more peaceful strategies. (3) Aggression can be interpreted as a punishment when it is directed toward a transgressor. In this case, aggression is motivated by restoration of a social justice, and thus its intensity is determined by the perceived moral responsibility of the transgressor. Further, it was indicated that aggression is intensified if it is justified as a sanctional conduct against the immoral. (4) Aggression can be also evoked when an individual's social identity is threatened. It was suggested that impression management motives are involved in aggression by an unexpected finding that the presence of audience or the identifiability rather facilitated retaliative aggression. The aggression-inhibition effect of apology was also explained in terms of impression management. In conclusion, it was presented that aggression is a behavioral strategy as an attempt to resolve interpersonal conflicts

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

    PubMed

    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.

    Coyne, Sarah M; Nelson, David A; Graham-Kevan, Nicola; Tew, Emily; Meng, K Nathan; Olsen, Joseph A

    2011-01-01

    Various studies have found that viewing physical or relational aggression in the media can impact subsequent engagement in aggressive behavior. However, this has rarely been examined in the context of relationships. Accordingly, the aim of this study was to examine the connection between viewing various types of aggression in the media and perpetration of aggression against a romantic partner. A total of 369 young adults completed a variety of questionnaires asking for their perpetration of various forms of relationship aggression. Participants' exposure to both physical and relational aggression in the media was also assessed. As a whole, we found a relationship between viewing aggression in the media and perpetration of aggression; however, this depended on the sex of the participant and the type of aggression measured. Specifically, exposure to physical violence in the media was related to engagement in physical aggression against their partner only for men. However, exposure to relational aggression in the media was related to romantic relational aggression for both men and women.

    Background Aggression is a major public health issue and is integral to several mental health disorders. Antiepileptic drugs may reduce aggression by acting on the central nervous system to reduce neuronal hyper-excitability associated with aggression. Objectives To evaluate the efficacy of antiepileptic drugs in reducing aggression and associated impulsivity. Search methods We searched CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, metaRegister of Controlled Trials (mRCT) and ClinicalTrials.gov to April 2009. We also searched Cochrane Schizophrenia Group’s register of trials on aggression, National Research Record and handsearched for studies. Selection criteria Prospective, placebo-controlled trials of antiepileptic drugs taken regularly by individuals with recurrent aggression to reduce the frequency or intensity of aggressive outbursts. Data collection and analysis Three authors independently selected studies and two authors independently extracted data. We calculated standardised mean differences (SMDs), with odds ratios (ORs) for dichotomous data. Main results Fourteen studies with data from 672 participants met the inclusion criteria. Five different antiepileptic drugs were examined. Sodium valproate/divalproex was superior to placebo for outpatient men with recurrent impulsive aggression, for impulsively aggressive adults with cluster B personality disorders, and for youths with conduct disorder, but not for children and adolescents with pervasive developmental disorder. Carbamazepine was superior to placebo in reducing acts of self-directed aggression in women with borderline personality disorder, but not in children with conduct disorder. Oxcarbazepine was superior to placebo for verbal aggression and aggression against objects in adult outpatients. Phenytoin was superior to placebo on the frequency of aggressive acts in male prisoners and in outpatient men including those with personality disorder, but not on the frequency of ‘behavioral incidents’ in

    The Research Domain Criteria (RDoC) address three types of aggression: frustrative non-reward, defensive aggression and offensive/proactive aggression. This review sought to present the evidence for genetic underpinnings of aggression and to determine to what degree prior studies have examined phenotypes that fit into the RDoC framework. Although the constructs of defensive and offensive aggression have been widely used in the animal genetics literature, the human literature is mostly agnostic with regard to all the RDoC constructs. We know from twin studies that about half the variance in behavior may be explained by genetic risk factors. This is true for both dimensional, trait-like, measures of aggression and categorical definitions of psychopathology. The non-shared environment seems to have a moderate influence with the effects of shared environment being unclear. Human molecular genetic studies of aggression are in an early stage. The most promising candidates are in the dopaminergic and serotonergic systems along with hormonal regulators. Genome-wide association studies have not yet achieved genome-wide significance, but current samples are too small to detect variants having the small effects one would expect for a complex disorder. The strongest molecular evidence for a genetic basis for aggression comes from animal models comparing aggressive and non-aggressive strains or documenting the effects of gene knockouts. Although we have learned much from these prior studies, future studies should improve the measurement of aggression by using a systematic method of measurement such as that proposed by the RDoC initiative.

    Krahé, Barbara; Möller, Ingrid; Huesmann, L Rowell; Kirwil, Lucyna; Felber, Juliane; Berger, Anja

    2011-04-01

    This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content.

    Liu, Jianghong; Lewis, Gary; Evans, Lois

    2012-01-01

    Aggressive behavior is the observable manifestation of aggression and is often associated with developmental transitions and a range of medical and psychiatric diagnoses across the lifespan. As healthcare professionals involved in the medical and psychosocial care of patients from birth through death, nurses frequently encounter—and may serve as—both victims and perpetrators of aggressive behavior in the workplace. While the nursing literature has continually reported research on prevention and treatment approaches, less emphasis has been given to understanding the etiology, including contextual precipitants of aggressive behavior. This paper provides a brief review of the biological, social, and environmental risk factors that purportedly give rise to aggressive behavior. Further, many researchers have focused specifically on aggressive behavior in adolescence and adulthood. Less attention has been given to understanding the etiology of such behavior in young children and older adults. This paper emphasizes the unique risk factors for aggressive behavior across the developmental spectrum, including childhood, adolescence, adulthood, and late life. Appreciation of the risk factors of aggressive behavior, and, in particular, how they relate to age-specific manifestations, can aid nurses in better design and implementation of prevention and treatment programs.

    2000-01-01

    The ruffe, Gymnocephalus cernuus, is a nonindigenous percid in the Great Lakes. Ruffe are aggressive benthivores and forage over soft substrates. Laboratory studies in pools (100 cm in diameter, 15 cm water depth) were conducted to determine whether fish density (low = 2, medium = 4, high = 6 ruffe per pool) changed foraging and aggressive behaviors with a limited food supply of chironomid larvae. All fish densities demonstrated a hierarchy based on aggressive interactions, but ruffe were most aggressive at low and high fish densities. Time spent in foraging was lowest at the low fish density. The best forager at the low fish density was the most aggressive individual, but the second most aggressive fish at the medium and high fish density was the best forager and also the one chased most frequently. A medium fish density offered the best energetic benefits to ruffe by providing the lowest ratio of time spent in aggression to that spent foraging. Based on our results, ruffe should grow best at an intermediate density. With high ruffe densities, we would also expect disparity in size as the more aggressive fish are able to garner a disproportionate amount of the resources. Alternatively, as the Great Lakes are a fairly open system, ruffe could migrate out of one area to colonize another as populations exceed optimal densities.

    2005-04-01

    The present study examined the relationship between aggression and game location in rugby league. We videotaped a random sample of 21 professional rugby league games played in the 2000 Super League season. Trained observers recorded the frequency of aggressive behaviours. Consistent with previous research, which used territoriality theories as a basis for prediction, we hypothesized that the home team would behave more aggressively than the away team. The results showed no significant difference in the frequency of aggressive behaviours exhibited by the home and away teams. However, the away teams engaged in substantially more aggressive behaviours in games they lost compared with games they won. No significant differences in the pattern of aggressive behaviours for home and away teams emerged as a function of game time (i.e. first or second half) or game situation (i.e. when teams were winning, losing or drawing). The findings suggest that while home and away teams do not display different levels of aggression, the cost of behaving aggressively (in terms of game outcome) may be greater for the away team.

    Today vertebral hemangioma is not completely understood entity, neither its pathogenesis nor optimal treatment is determined. Nowadays in majority of clinics in this country ineffective radiotherapy remains the first-line treatment. We analyzed results of treatment of 205 patients (286 lesions) with aggressive hemangiomas operated in Department of Neurosurgery of Military Medical Academy and Department of Nuclear Medicine of of Russian Scientific Center of Radiological and Surgical Technologies (Saint-Petersburg, Russia) since 1999 till 2009. Percutaneus vertebroplasty was performed in 167 lesions, radiotherapy was applied in 119 aggressive hemangiomas. Vertebroplasty is more effective for treatment of aggressive hemangiomas in comparison with radiotherapy. Signs of hemangiomas aggression, indications for surgery, and tactics of management were determined. Use of percutaneous vertebroplasty for treatment of aggressive hemangiomas resulted in fast recovery of the patients. This procedure is minimally invasive, it reduces hospital stay and duration of recovery.

    Aggressive/attacking and helpful/emphatic/prosocial behaviors are extremely important in human relationships. Both high levels of aggression and deficits of prosociality play important role in the development and conservation of mental disorders. We review the measurement options and clinical importance of aggressive and prosocial behavior. The typical developmental pathways and the genetic and environmental background of these behaviors are presented. The clinical tools used in the measurement of aggression and prosociality are summarized in the present paper, with specific attention on questionnaires applied in Hungarian practice. The connections between diagnostic categories (conduct disorder, oppositional-defiant disorder, attention deficit and hyperactive disorder, autism spectrum disorders) and the two behaviors are evaluated. In the end, we present those additional research projects that explore the cognitive-emotional background of aggressive or prosocial behavior with clinical relevance either in the diagnosis or in the treatment of child psychiatric diseases.

  4. Secular trends in physiological capital: implications for equity in health care.

    PubMed

    Fogel, Robert W

    2003-01-01

    Over the past three centuries, there has been a rapid accumulation of physiological capital in Organisation for Economic Cooperation and Development (OECD) countries. Enhanced physiological capital is tied to long-term reduction in environmental hazards and to the conquest of chronic malnutrition, since both nutritional status and the quality of the external and intrauterine environments appear to be linked to the quality of organ development and to the onset of chronic diseases later in life. Data on heights and birth weights suggest that physiological capital has become more equally distributed, thereby reducing socioeconomic disparities in the burden of disease. These developments have a number of health care policy implications: (1) enhanced physiological capital has done more to reduce inequities in health status than has wider access to health care; (2) the main contribution of more advanced medical treatment so far has been to retard depreciation in individuals' physiological capital; (3) prenatal and early childhood care and environmental issues are key for interventions aimed at enhancing physiological capital and at affecting its rate of depreciation; (4) lifestyle change is the most important issue affecting health equity in rich countries; and (5) greater access to clinical care should be promoted through aggressive outreach, since expanded insurance coverage by itself is inadequate.

  6. When do normative beliefs about aggression predict aggressive behavior? An application of I3 theory.

    PubMed

    2015-01-01

    I(3) theory assumes that aggressive behavior is dependent on three orthogonal processes (i.e., Instigator, Impellance, and Inhibition). Previous studies showed that Impellance (trait aggressiveness, retaliation tendencies) better predicted aggression when Instigator was strong and Inhibition was weak. In the current study, we predicted that another Impellance (i.e., normative beliefs about aggression) might predict aggression when Instigator was absent and Inhibition was high (i.e., the perfect calm proposition). In two experiments, participants first completed the normative beliefs about aggression questionnaire. Two weeks later, participants' self-control resources were manipulated either using the Stroop task (study 1, N = 148) or through an "e-crossing" task (study 2, N = 180). Afterwards, with or without being provoked, participants played a game with an ostensible partner where they had a chance to aggress against them. Study 1 found that normative beliefs about aggression negatively and significantly predicted aggressive behavior only when provocation was absent and self-control resources were not depleted. In Study 2, normative beliefs about aggression negatively predicted aggressive behavior at marginal significance level only in the "no-provocation and no-depletion" condition. In conclusion, the current study provides partial support for the perfect calm proposition and I(3) theory.

    The present study examined the importance of psychopathy-linked narcissism in predicting proactive and reactive aggression and conduct problems in a group of 160 moderately to highly aggressive children (mean age of 10 years, 9 months). Children's self-report of self-esteem and parent and teacher report of dimensions of psychopathy [narcissism, callous-unemotional (CU) traits, and impulsivity], proactive and reactive aggression, and conduct problems were collected. Composites of parent and teacher ratings of children's behavior were used. Consistent with the study's hypotheses, narcissism predicted unique variance in both proactive and reactive aggression, even when controlling for other dimensions of psychopathy, demographic variables associated with narcissism, and the alternative subtype of aggression. As hypothesized, impulsivity was significantly associated with only reactive aggression. CU traits were not related to proactive or reactive aggression once the control variables were entered. All dimensions of psychopathy predicted unique variance in conduct problems. Consistent with prediction, narcissism was not significantly related to general self-esteem, providing support that narcissism and self-esteem are different constructs. Furthermore, narcissism and self-esteem related differentially to proactive aggression, reactive aggression, and conduct problems. Furthermore, narcissism but not self-esteem accounted for unique variance in aggression and conduct problems. The importance of narcissism in the prediction of aggressive behaviors and clinical implications are discussed.

  8. Transmission line capital costs

    The displacement or deferral of conventional AC transmission line installation is a key benefit associated with several technologies being developed with the support of the U.S. Department of Energy`s Office of Energy Management (OEM). Previous benefits assessments conducted within OEM have been based on significantly different assumptions for the average cost per mile of AC transmission line. In response to this uncertainty, an investigation of transmission line capital cost data was initiated. The objective of this study was to develop a database for preparing preliminary estimates of transmission line costs. An extensive search of potential data sources identified databases maintained by the Bonneville Power Administration (BPA) and the Western Area Power Administration (WAPA) as superior sources of transmission line cost data. The BPA and WAPA data were adjusted to a common basis and combined together. The composite database covers voltage levels from 13.8 to 765 W, with cost estimates for a given voltage level varying depending on conductor size, tower material type, tower frame type, and number of circuits. Reported transmission line costs vary significantly, even for a given voltage level. This can usually be explained by variation in the design factors noted above and variation in environmental and land (right-of-way) costs, which are extremely site-specific. Cost estimates prepared from the composite database were compared to cost data collected by the Federal Energy Regulatory Commission (FERC) for investor-owned utilities from across the United States. The comparison was hampered because the only design specifications included with the FERC data were voltage level and line length. Working within this limitation, the FERC data were not found to differ significantly from the composite database. Therefore, the composite database was judged to be a reasonable proxy for estimating national average costs.

    Researching the correlates of men's sexually aggressive behavior (i.e., verbal coercion and rape) is critical to both understanding and preventing sexual aggression. This study examined 120 men who completed an anonymous online questionnaire. The study aimed to determine the relative importance of two potential correlates of men's self-reported use of sexual aggression: (a) perceptions that male peers use and support sexual aggression and (b) perceptions of punishment likelihood associated with sexual aggression. Results revealed that perceptions of male friends' acceptance of sexual aggression were strongly associated with individual men's reports of using verbal coercion and rape. Perceptions of punishment likelihood were negatively correlated with verbal coercion but not with rape through intoxication and force. Implications for sexual aggression prevention are discussed.

    Research suggests that early classroom experiences influence the socialization of aggression. Tracking changes in the aggressive behavior of 4179 children from kindergarten to second-grade (ages 5–8) this study examined the impact of two important features of the classroom context–aggregate peer aggression and climates characterized by supportive teacher-student interactions. The aggregate aggression scores of children assigned to first-grade classrooms predicted the level of classroom aggression (assessed by teacher ratings) and quality of classroom climate (assessed by observers) that emerged by the end of grade 1. HLM analyses revealed that first-grade classroom aggression and quality of classroom climate made independent contributions to changes in student aggression, as students moved from kindergarten to second grade. Implications for policy and practice are discussed. PMID:21434887

    Types of perpetrators of workplace aggression can vary considerably, and recent research has demonstrated that aggression from different perpetrator categories has different implications for victims. We extended research on multifoci aggression and explored affective and cognitive pathways linking verbal aggression from four perpetrator types--supervisors, coworkers, customers, and significant others--and employee morale and turnover intention. Data from a sample of 446 working adults indicated that both emotional strain and employees' corresponding judgments of their social exchange relationships with these perpetrators served as the mechanisms for the association between aggression from supervisors, coworkers, and customers and morale and turnover intention. Coworker aggression had a direct association with turnover intention and significant other aggression was related to turnover intention only through emotional strain. The theoretical and practical implications of these findings are discussed.

    Aggression and violence are widespread in UK Mental Health Trusts, and are accompanied by negative psychological and physiological consequences for both staff and other patients. Patients who are younger, male, and have a history of substance use and psychosis diagnoses are more likely to display aggression; however, patient factors are not solely responsible for violence, and there are complex circumstances that lead to aggression. Indeed, patient-staff interactions lead to a sizeable portion of aggression and violence on inpatient units, thus they cannot be viewed without considering other forms of conflict and containment that occur before, during, and after the aggressive incident. For this reason, we examined sequences of aggressive incidents in conjunction with other conflict and containment methods used to explore whether there were particular profiles to aggressive incidents. In the present study, 522 adult psychiatric inpatients from 84 acute wards were recruited, and there were 1422 incidents of aggression (verbal, physical against objects, and physical). Cluster analysis revealed that aggressive incident sequences could be classified into four separate groups: solo aggression, aggression-rule breaking, aggression-medication, and aggression-containment. Contrary to our expectations, we did not find physical aggression dominant in the aggression-containment cluster, and while verbal aggression occurred primarily in solo aggression, physical aggression also occurred here. This indicates that the management of aggression is variable, and although some patient factors are linked with different clusters, these do not entirely explain the variation.

    The aim of this study was to identify implicit cognitive predictors of aggressive behavior. Specifically, the predictive value of an attentional bias for aggressive stimuli and automatic association of the self and aggression was examined for reactive and proactive aggressive behavior in a non-clinical sample (N = 90). An Emotional Stroop Task was used to measure an attentional bias. With an idiographic Single-Target Implicit Association Test, automatic associations were assessed between words referring to the self (e.g., the participants' name) and words referring to aggression (e.g., fighting). The Taylor Aggression Paradigm (TAP) was used to measure reactive and proactive aggressive behavior. Furthermore, self-reported aggressiveness was assessed with the Reactive Proactive Aggression Questionnaire (RPQ). Results showed that heightened attentional interference for aggressive words significantly predicted more reactive aggression, while lower attentional bias towards aggressive words predicted higher levels of proactive aggression. A stronger self-aggression association resulted in more proactive aggression, but not reactive aggression. Self-reports on aggression did not additionally predict behavioral aggression. This implies that the cognitive tests employed in our study have the potential to discriminate between reactive and proactive aggression. Aggr.

    The conventional technique for percutaneous nephrolithotomy (PNL) ends by placing a nephrostomy tube within the access tract. However, feasibility and safety of tubeless PNL have been widely demonstrated. In this modification, a ureteral stent is usually left in place instead of the nephrostomy tube. The aim of this study is to compare the use of a postoperative indwelling double-J stent versus an overnight-externalized ureteral catheter in patients undergoing tubeless PNL. Sixty-eight patients undergoing tubeless PNL were randomized either for a postoperative double-J stent (group 1) or for an overnight-externalized ureteral catheter (group 2). Outcomes evaluated included postoperative pain, hospital stay length, incidence of hemorrhagic complications, residual lithiasis and urinary leakage. Groups were similar according to age, sex, body mass index and stone burden. There were no significant differences in terms of postoperative pain, incidence of perirenal hematomas, residual lithiasis and urinary leakage. However, patients in group 1 presented longer hospital stays (3.7 ± 1.7 vs. 1.9 ± 0.3 days; p < 0.001) and greater hematocrit drops (4.9 ± 2.2 vs. 2.1 ± 1.8 %; p < 0.001). Our results confirm that among patients undergoing tubeless PNL, both alternatives (i.e. leaving a double-J stent or an overnight-externalized ureteral catheter) are reliable and safe. However, further considerations, like the need of double-J stent removal under cystoscopy, need to be taken into account when deciding which modality to use.

    Aggression and violence represent a significant public health concern and a clinical challenge for the mental healthcare provider. A great deal has been revealed regarding the neurobiology of violence and aggression, and an integration of this body of knowledge will ultimately serve to advance clinical diagnostics and therapeutic interventions. We will review here the latest findings regarding the neurobiology of aggression and violence. First, we will introduce the construct of aggression, with a focus on issues related to its heterogeneity, as well as the importance of refining the aggression phenotype in order to reduce pathophysiologic variability. Next we will examine the neuroanatomy of aggression and violence, focusing on regional volumes, functional studies, and interregional connectivity. Significant emphasis will be on the amygdala, as well as amygdala-frontal circuitry. Then we will turn our attention to the neurochemistry and molecular genetics of aggression and violence, examining the extensive findings on the serotonergic system, as well as the growing literature on the dopaminergic and vasopressinergic systems. We will also address the contribution of steroid hormones, namely, cortisol and testosterone. Finally, we will summarize these findings with a focus on reconciling inconsistencies and potential clinical implications; and, then we will suggest areas of focus for future directions in the field.

    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.

    Although fairly frequent in psychiatric in-patient, episodes of aggression/violence are mainly limited to verbal aggression, but the level of general health is significantly lower in nurses who report 'frequent' exposure to violent incidents, and there is disagreement between patients and staff concerning predictors of these episodes. We searched the Pubmed, Embase and PsychInfo databases for English, Italian, French or German language papers published between 1 January 1990 and 31 March 2010 using the key words "aggress*" (aggression or aggressive) "violen*" (violence or violent) and "in-patient" or "psychiatric wards", and the inclusion criterion of an adult population (excluding all studies of selected samples such as a specific psychiatric diagnosis other than psychosis, adolescents or the elderly, men/women only, personality disorders and mental retardation). The variables that were most frequently associated with aggression or violence in the 66 identified studies of unselected psychiatric populations were the existence of previous episodes, the presence of impulsiveness/hostility, a longer period of hospitalisation, non-voluntary admission, and aggressor and victim of the same gender; weaker evidence indicated alcohol/drug misuse, a diagnosis of psychosis, a younger age and the risk of suicide. Alcohol/drug misuse, hostility, paranoid thoughts and acute psychosis were the factors most frequently involved in 12 studies of psychotic patients. Harmony among staff (a good working climate) seems to be more useful in preventing aggression than some of the other strategies used in psychiatric wards, such as the presence of male nurses.

  1. 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.

  2. Testosterone and aggressive behavior in man.

    PubMed

    Batrinos, Menelaos L

    2012-01-01

    Atavistic residues of aggressive behavior prevailing in animal life, determined by testosterone, remain attenuated in man and suppressed through familial and social inhibitions. However, it still manifests itself in various intensities and forms from; thoughts, anger, verbal aggressiveness, competition, dominance behavior, to physical violence. Testosterone plays a significant role in the arousal of these behavioral manifestations in the brain centers involved in aggression and on the development of the muscular system that enables their realization. There is evidence that testosterone levels are higher in individuals with aggressive behavior, such as prisoners who have committed violent crimes. Several field studies have also shown that testosterone levels increase during the aggressive phases of sports games. In more sensitive laboratory paradigms, it has been observed that participant's testosterone rises in the winners of; competitions, dominance trials or in confrontations with factitious opponents. Aggressive behavior arises in the brain through interplay between subcortical structures in the amygdala and the hypothalamus in which emotions are born and the prefrontal cognitive centers where emotions are perceived and controlled. The action of testosterone on the brain begins in the embryonic stage. Earlier in development at the DNA level, the number of CAG repeats in the androgen receptor gene seems to play a role in the expression of aggressive behavior. Neuroimaging techniques in adult males have shown that testosterone activates the amygdala enhancing its emotional activity and its resistance to prefrontal restraining control. This effect is opposed by the action of cortisol which facilitates prefrontal area cognitive control on impulsive tendencies aroused in the subcortical structures. The degree of impulsivity is regulated by serotonin inhibiting receptors, and with the intervention of this neurotransmitter the major agents of the neuroendocrine

    Aggression is commonly reported in individuals with Huntington's disease (HD). While correlating factors for aggression are often speculated about, features that are associated with, and contribute to, aggression in this population have not been clearly determined. This systematic review investigates rates of aggression and treatment options for aggression in HD. A number of key findings were revealed. Studies reporting on rates of aggression revealed that its prevalence is high, falling between 22 and 66 percent in the majority of studies. Aggression may be more common in males with HD, and is also found in higher rates in individuals who experience frequent falls, have obsessive-compulsive symptoms and suicidal ideation. There is little research investigating antecedents for aggression in HD. A wide variety of psychotropic medications have been reported in the literature to treat individuals with HD and aggressive behaviour. However, due to methodological limitations, no treatment recommendations can be made, based on the current literature. Two non-medication therapies have been investigated, behaviour support and sensory modulation intervention. However, again, due to methodological limitations with these studies, further research is needed before they can be recommended as frontline interventions. This review highlights the need for further methodologically rigorous studies investigating the treatment of aggression in HD.

    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.

    Accumulating evidence suggests that emotion dysregulation is associated with psychopathology. This paper provides a review of recent longitudinal studies that investigate the relationship between emotion regulation and aggressive behavior in childhood age. While there is substantial evidence for assuming a close relation of emotion regulation and aggressive behavior, moderating and mediating factors like gender and peer rejection have been established. Furthermore, results suggest emotion dysregulation as an important risk factor of aggressive behavior. Several directions for future research are pointed out to further validate and refine the reviewed relationships.

  7. Financial capital and intellectual capital in physician practice management.

    PubMed

    Robinson, J C

    1998-01-01

    Medical groups need financial resources yet most retain no earnings and have no reserves. Physician practice management (PPM) companies have recognized the need for investment and the scarcity of indigenous capital in the physician sector and are rushing to fill the void. Resources are being contributed by venture capitalists, bond underwriters, private investors, pharmaceutical manufacturers, health plans, hospital systems, and public equity markets. The potential contribution of PPM firms is to nurture the intellectual capital of leading physician organizations and diffuse it throughout the health care system. The risk is that short-term financial imperatives will impede necessary long-term investments.

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

    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.

    Our long term interest is to develop a developmental model of impulsive aggression based on a confluence of social, psychological and biological features. This approach incorporates neurobiological research, which has identified language processing deficits as a unique characteristic of impulsive aggressors and extends it to include emotional deficits. As an initial test of this hypothesis, we examined whether empathy and alexithymia were associated with impulsive aggression. Regressions were performed to explore the associations among impaired empathy, alexithymia, impulsive aggression, verbal and physical general aggression. Among impulsive aggressive veterans (n=38) recruited from a VA trauma clinic, alexithymia predicted impulsive aggression and empathic deficits predicted verbal aggression. Neither emotional awareness deficit predicted general physical aggression in this middle-aged sample. Results suggested that empathic deficits were associated with general verbal aggression, but alexithymia was uniquely associated with impulsive aggression. Consideration of alexithymia in impulsive aggression has implications for its etiology, prevention and treatment.

I discuss a range of micro evidence, which finds that health is both human capital itself and an input to producing other forms of human capital. I use a standard model to integrate these results, and suggest a re-interpretation of much of the micro literature. I then discuss the aggregate implications of micro estimates, but note the complications in extrapolating to general equilibrium, especially because of health’s effect on population size. I also review the macro evidence on this topic, which consists of either cross-country comparisons or measuring responses to health shocks. Micro estimates are 1–2 orders of magnitude smaller than the cross-country relationship, but nevertheless imply high benefit-to-cost ratios from improving certain forms of health. PMID:24147187

    This paper provides estimates of the cost of equity and debt capital to for-profit and non-profit hospitals in the U.S. for the years 1972-83. The cost of equity is estimated using, alternatively, the Capital Asset Pricing Model and Arbitrage Pricing Theory. We find that the cost of equity capital, using either model, substantially exceeded anticipated inflation. The cost of debt capital was much lower. Accounting for the corporate tax shield on debt and capital paybacks by cost-based insurers lowered the net cost of capital to hospitals.

  13. Human capital, schooling and health.

    2003-06-01

    A consensus has been forged in the last decade that recent periods of sustained growth in total factor productivity and reduced poverty are closely associated with improvements in a population's child nutrition, adult health, and schooling, particularly in low-income countries. Estimates of the productive returns from these three forms of human capital investment are nonetheless qualified by a number of limitations in our data and analytical methods. This paper reviews the problems that occupy researchers in this field and summarizes accumulating evidence of empirical regularities. Social experiments must be designed to assess how randomized policy interventions motivate families and individuals to invest in human capital, and then measure the changed wage opportunities of those who have been induced to make these investments. Statistical estimation of wage functions that seek to represent the relationship between wage rates and a variety of human capital stocks may yield biased estimates of private rates of return from these investments for a variety of reasons. The paper summarizes several of these problems and illustrates how data and statistical methods can be used to deal with some of them. The measures of labor productivity and the proxies specified for schooling and adult health are first discussed, and then the functional relationships between human capital and wages are described. Three types of estimation problem are discussed: (1) bias due to omitted variables, such as ability or frailty; (2) bias due to the measurement of an aggregation of multiple sources of human capital, e.g. genetic and socially reproducible variation, which may contribute to different gains in worker productivity; and (3) errors in measurement of the human capital stocks. Empirical examples and illustrative estimates are surveyed.

    The long-term effect of an AA solution based on Travasol, a solution for total parenteral nutrition, given intraperitoneally over a 6-month period was studied in 5 patients 22 to 75 years old, having been on continuous ambulatory peritoneal dialysis (CAPD) for 3 to 57 months. A low oral protein intake (less than 0.8 g/kg bw/day) and/or a low serum albumin (less than 35 g/L) were used as inclusion criteria. Two liters of 1% AA solution were infused overnight, while a glucose Dianeal was used for the other exchanges. During the study, BUN increased from 22.04 mM/L to 28.06 mM/L the first month and remained at these levels, indicating the increased protein intake. However, average oral total energy and protein intake, body weight (bw), serum creatinine, cholesterol, triglycerides, total proteins, albumin, transferrin, skinfold thickness, total body potassium, and plasma AA levels remained basically unchanged. The average total body nitrogen decreased from 1.746 to 1.554 Kg, but this decrease did not reach statistical significance (p greater than 0.05). We conclude that intraperitoneal overnight administration of 2 L of 1% AA based on Travasol over 6 months did not improve the nutritional status of CAPD patients. This ineffectiveness might be due to the AA composition of the solution, the timing of administration, or to a low caloric intake and/or that our patients were not severely malnourished.

    The wealth and value of organizations are increasingly based on intellectual capital. Although acquiring talented individuals and investing in employee learning adds value to the organization, reaping the benefits of intellectual capital involves translating the wisdom of employees into reusable and sustained actions. This requires a culture that creates employee commitment, encourages learning, fosters sharing, and involves employees in decision making. An infrastructure to recognize and embed promising and best practices through social networks, evidence-based practice, customization of innovations, and use of information technology results in increased productivity, stronger financial performance, better patient outcomes, and greater employee and customer satisfaction.

    PubMed Central

    Takahashi, Aki; Quadros, Isabel M.; de Almeida, Rosa M. M.; Miczek, Klaus A.

    2013-01-01

    Serotonin (5-HT) has long been considered as a key transmitter in the neurocircuitry controlling aggression. Impaired regulation of each subtype of 5-HT receptor, 5-HT transporter, synthetic and metabolic enzymes has been linked particularly to impulsive aggression. The current summary focuses mostly on recent findings from pharmacological and genetic studies. The pharmacological treatments and genetic manipulations or polymorphisms of a specific target (e.g., 5-HT1A receptor) can often result in inconsistent results on aggression, due to “phasic” effects of pharmacological agents vs “trait”-like effects of genetic manipulations. Also, the local administration of a drug using the intracranial microinjection technique has shown that activation of specific subtypes of 5-HT receptors (5-HT1A and 5-HT1B) in mesocorticolimbic areas can reduce species-typical and other aggressive behaviors, but the same receptors in the medial prefrontal cortex or septal area promote escalated forms of aggression. Thus, there are receptor populations in specific brain regions that preferentially modulate specific types of aggression. Genetic studies have shown important gene × environment interactions; it is likely that the polymorphisms in the genes of 5-HT transporters (e.g., MAO A) or rate-limiting synthetic and metabolic enzymes of 5-HT determine the vulnerability to adverse environmental factors that escalate aggression. We also discuss the interaction between the 5-HT system and other systems. Modulation of 5-HT neurons in the dorsal raphe nucleus by GABA, glutamate, and CRF profoundly regulate aggressive behaviors. Also, interactions of the 5-HT system with other neuropeptides (arginine vasopressin, oxytocin, neuropeptide Y, opioid) have emerged as important neurobiological determinants of aggression. Studies of aggression in genetically modified mice identified several molecules that affect the 5-HT system directly (e.g., Tph2, 5-HT1B, 5-HT transporter, Pet1, MAOA) or

  1. Female competition and aggression: interdisciplinary perspectives

    PubMed Central

    Stockley, Paula; Campbell, Anne

    2013-01-01

    This paper introduces a Theme Issue combining interdisciplinary perspectives in the study of female competition and aggression. Despite a history of being largely overlooked, evidence is now accumulating for the widespread evolutionary significance of female competition. Here, we provide a synthesis of contributions to this Theme Issue on humans and other vertebrates, and highlight directions for future research. Females compete for resources needed to survive and reproduce, and for preferred mates. Although female aggression takes diverse forms, under most circumstances relatively low-risk competitive strategies are favoured, most probably due to constraints of offspring production and care. In social species, dominance relationships and threats of punishment can resolve social conflict without resort to direct aggression, and coalitions or alliances may reduce risk of retaliation. Consistent with these trends, indirect aggression is a low cost but effective form of competition among young women. Costs are also minimized by flexibility in expression of competitive traits, with aggressive behaviour and competitive signalling tailored to social and ecological conditions. Future research on female competition and the proximate mediators of female aggression will be greatly enhanced by opportunities for interdisciplinary exchange, as evidenced by contributions to this Theme Issue.

    Our recent studies showed that brain areas that are activated in a model of escalated aggression overlap with those that promote predatory aggression in cats. This finding raised the interesting possibility that the brain mechanisms that control certain types of abnormal aggression include those involved in predation. However, the mechanisms of predatory aggression are poorly known in rats, a species that is in many respects different from cats. To get more insights into such mechanisms, here we studied the brain activation patterns associated with spontaneous muricide in rats. Subjects not exposed to mice, and those which did not show muricide were used as controls. We found that muricide increased the activation of the central and basolateral amygdala, and lateral hypothalamus as compared to both controls; in addition, a ventral shift in periaqueductal gray activation was observed. Interestingly, these are the brain regions from where predatory aggression can be elicited, or enhanced by electrical stimulation in cats. The analysis of more than 10 other brain regions showed that brain areas that inhibited (or were neutral to) cat predatory aggression were not affected by muricide. Brain activation patterns partly overlapped with those seen earlier in the cockroach hunting model of rat predatory aggression, and were highly similar with those observed in the glucocorticoid dysfunction model of escalated aggression. These findings show that the brain mechanisms underlying predation are evolutionarily conservative, and indirectly support our earlier assumption regarding the involvement of predation-related brain mechanisms in certain forms of escalated social aggression in rats.

    This study assessed the association between indirectly measured behavioural approach- and avoidance-related tendencies on the one hand, and reactive versus proactive aggression on the other hand. Reactive aggression (i.e. the impulsive, anger-driven aggression expressed in response to threatening stimuli) was differentiated from proactive aggression (i.e. the more controlled aggression motivated towards obtaining specific goals). A mixed sample of 118 patients and healthy controls filled out a self-report measure to assess their degree of reactive and proactive aggression, and then performed an Approach Avoidance Task in which they were asked to pull or push a joystick in response to a format-feature of a series of pictures, irrespective of their contents. The pictorial stimuli used in this task included attack-related scenes and angry faces, along with neutral, positive and negative control stimuli. The results were controlled for the level of personality disorder pathology, gender, and age. The findings indicated that reactive but not proactive aggression was related to the relative behavioural tendency to approach attack-related scenes, along with positive stimuli. These findings reflect the hyper-reactivity of the approach-related reward system in reactive aggression, and further our knowledge into the distinct correlates and precursors of reactive and proactive aggression.

    Although alcohol consumption is involved in most acts of violence, most people do not become violent when they drink. Individuals also respond differently to alcohol on laboratory measures of aggression. The objective of this study was to determine whether individual differences in the effects of alcohol on a laboratory measure of aggression are related to specific personality traits and/or serotonin function, as measured by prolactin response to pharmacochallenge. Psychometric scales for impulsiveness, aggression, and anger, as well as a probe for suspiciousness, were administered to 10 healthy male social drinkers. Trait serotonin function was determined by citalopram challenge. The effect of alcohol on the Point Subtraction Aggression Paradigm was determined by comparing aggression scores with and without 1 g/kg alcohol. Impulsivity scores were significantly correlated with the change in aggressive responding after alcohol. Aggression, anger, and suspiciousness scores were not. Prolactin response did not predict the effect of alcohol on aggressive responding. The results suggest that trait impulsiveness may mediate the effects of alcohol on aggression in normal males.

    Abstract Intimate partner aggression is a leading cause of injury among women of child-bearing age. Research suggests that pregnancy and the postpartum period are times of increased vulnerability to aggression. Since rural women are at an increased risk of intimate partner aggression, research is needed to examine the role of pregnancy and the presence of children on intimate partner aggression among this vulnerable population. The purpose of this study is to examine the association between young children and intimate partner aggression victimization and perpetration among a rural sample. This analysis utilized data from biologic females of child-bearing age from the Keokuk County Rural Health Study, a cohort study of over 1,000 rural families conducted from 1994 to 2011. Crude and adjusted logistic regression was used to determine the relationship between having a young child and experiencing four forms of intimate partner aggression: verbal aggression perpetration, verbal aggression victimization, physical aggression perpetration, and physical aggression victimization. Having young children was significantly associated with increased odds of perpetrating verbal aggression but not victimization of verbal aggression or perpetration and victimization of physical aggression. This significant relationship persisted after adjustment for education, employment, or location of residence but not age or marital status. The increased odds of perpetrating verbal aggression among mothers in a rural area highlight the need for interventions designed for rural parents. One method of reducing intimate partner aggression may be to incorporate intimate partner aggression prevention activities into existing child abuse intervention activities. PMID:27626037

    We report a study aimed at understanding the effects of classroom normative influences on individual aggressive behavior, using samples of 614 and 427 urban elementary school children. Participants were assessed with measures of aggressive behavior and normative beliefs about aggression. We tested hypotheses related to the effects of personal normative beliefs, descriptive classroom norms (the central tendency of classmates' aggressive behavior), injunctive classroom normative beliefs (classmates' beliefs about the acceptability of aggression), and norm salience (student and teacher sanctions against aggression) on longitudinal changes in aggressive behavior and beliefs. injunctive norms affected individual normative beliefs and aggression, but descriptive norms had no effect on either. In classrooms where students and teachers made norms against aggression salient, aggressive behavior diminished over time. Implications for classroom behavior management and further research are discussed.

    The objective of this study was to develop a questionnaire to assess child-to-parent aggression in adolescents and to document the extent of the problem. The questionnaire developed in this study, the Child-to-Parent Aggression Questionnaire (CPAQ), includes forms of physical and psychological aggression directed at both the mother and the father. It also includes open questions about the reasons for the aggressive acts. The CPAQ was completed by a sample of 2719 adolescents (age range: 13-18 years old, 51.4% girls). Confirmatory factor analysis supported a four-factor correlated structure (physical aggression against mother, physical aggression against father, psychological aggression against mother, and psychological aggression against father). Psychological and physical aggression against the mother was more frequent than against the father. However, there were no differences with regard to severe forms of aggression. Girls scored significantly higher on all indicators of psychological aggression, including severe psychological aggression. Nevertheless, except for the prevalence of physical aggression against mothers, which was higher in females, there were no significant differences in physical aggression against parents. Finally, the reasons provided by the adolescents for the aggression included both instrumental (e.g., to obtain permission to get home late and to access their computers) and reactive reasons (e.g., anger and self-defense). These findings highlight the complexity of child-to-parent aggression in adolescence.

    Individuals with greater social capital have better health outcomes. Investment in social capital likely increases one’s own social capital, bearing great implications for disease prevention and health promotion. In this study, the authors developed and validated the Social Capital Investment Inventory (SCII). Direct effects of social capital investment on perceived stress, and indirect effects through social capital were examined. 397 Participants from Beijing and Wuhan, China completed surveys. Analyses demonstrated that the SCII has a single factor structure and strong internal consistency. Structural equation modeling showed that individuals who invested more in social capital had greater bonding social capital, and subsequently less perceived stress. Results suggest that disease prevention and health promotion programs should consider approaches to encourage social capital investment; individuals may be able to reduce stress by increasing their investment in social capital. Future research is needed to provide additional empirical support for the SCII and observed structural relationships. PMID:25648725

    Thomas, Duane E; Bierman, Karen L

    2006-01-01

    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.

    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.

  12. Unsanctioned aggression in rugby union: relationships among aggressiveness, anger, athletic identity, and professionalization.

    PubMed

    Maxwell, J P; Visek, A J

    2009-01-01

    Aggressive players who intentionally cause injury to their opponents are common in many sports, particularly collision sports such as Rugby Union. Although some acts of aggression fall within the rules (sanctioned), others do not (unsanctioned), with the latter tending to be less acceptable than the former. This study attempts to identify characteristics of players who are more likely to employ unsanctioned methods in order to injure an opponent. Male Rugby Union players completed questionnaires assessing aggressiveness, anger, past aggression, professionalization, and athletic identity. Players were assigned to one of two groups based on self-reported past unsanctioned aggression. Results indicated that demographic variables (e.g., age, playing position, or level of play) were not predictive of group membership. Measures of aggressiveness and professionalization were significant predictors; high scores on both indicated a greater probability of reporting the use of unsanctioned aggressive force for the sole purpose of causing injury or pain. In addition, players who had been taught how to execute aggressive illegal plays without detection were also more likely to report using excessive force to injure an opponent. Results provide further support that highly professionalized players may be more likely to use methods outside the constitutive rules of Rugby Union in order to intentionally injure their opponents. Results are discussed within the context of the increasing win-at-all-cost attitude that is becoming more prevalent in sport and its implications for youth athletes.

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

    PubMed

    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.

  15. Cool and hot executive function as predictors of aggression in early childhood: Differentiating between the function and form of aggression.

    PubMed

    Poland, Sarah E; Monks, Claire P; Tsermentseli, Stella

    2016-06-01

    Executive function (EF) has been implicated in childhood aggression. Understanding of the role of EF in aggression has been hindered, however, by the lack of research taking into account the function and form of aggression and the almost exclusive focus on cool EF. This study examined the role of cool and hot EF in teacher reported aggression, differentiating between reactive and proactive as well as physical and relational aggression. Children (N = 106) completed laboratory tasks measuring cool (inhibition, planning, working memory) and hot EF (affective decision-making, delay of gratification). Cool, but not hot, EF significantly contributed to understanding of childhood aggression. Inhibition was a central predictor of childhood aggression. Planning and working memory, in contrast, were significant independent predictors of proactive relational aggression only. Added to this, prosocial behaviour moderated the relationship between working memory and reactive relational aggression. This study therefore suggests that cool EF, particularly inhibition, is associated with childhood aggression across the different functions and forms.

    Background Risk assessment instruments have become a preferred means for predicting future aggression, claiming to predict long-term aggression risk. Aims To investigate the predictive value over 12 months and 4 years of two commonly applied instruments (Historical, Clinical and Risk Management - 20 (HCR-20) and Violence Risk Appraisal Guide (VRAG)). Method Participants were adult male psychiatric patients detained in a high secure hospital. All had a diagnosis of personality disorder. The focus was on aggression in hospital. Results The actuarial risk assessment (VRAG) was generally performing better than the structured risk assessment (HCR-20), although neither approach performed particularly well overall. Any value in their predictive potential appeared focused on the longer time period under study (4 years) and was specific to certain types of aggression. Conclusions The value of these instruments for assessing aggression in hospital among patients with personality disorder in a high secure psychiatric setting is considered.

  4. Day Care vs Overnight Stay after Laparoscopic Cholecystectomy even with Co-morbidity and a Possible Second Surgery: A Patient’s Choice

    PubMed Central

    2016-01-01

    Introduction Laparoscopic Cholecystectomy (LC) has become the gold standard for symptomatic gall stone disease. It is being practiced as a day care procedure in healthy individuals in American Society of Anaesthesialogists (ASA) grade I and II. It is not yet established in presence of co-morbidity and when a second surgery is added. In most of the study, patient’s choice and the psycho-social factors were not considered in deciding the day care procedure. Aim To find the safety of LC and a second surgery as day care in presence of compensated co-morbidity. To study the choice of the patient whether to stay in hospital or go home after declaring them fit for day care. Materials and Methods All the patients of symptomatic cholelithiasis with co-morbidity and associations were evaluated and made uncompromising for elective surgery. All the LC were done at 8mmHg CO2 peumo-peritoneal pressure using harmonic scalpel as the energy source for dissection of gall bladder from the liver bed. Cases with conversion and placement of drain were excluded. Results A total of 1029 out of 1042 patients was included from Jan 2005 to Jan 2015. The age range was 38 to 91years (mean 44.65, SD 14.15). There were 634 females and 395 males. A total of 121(11.7%) of them had co-morbidity and associations. A total of 72(7%) had undergone a second surgery. Only 0.8% had real day care. A total of 95.7% had overnight stay even after fulfilling all the criteria. Only 0.2% needed re-admission in 30 days and one required intervention. Conclusion Patients like to stay over night in the hospital even if found fit for day care after LC. Overnight stay makes them happy, psycho-socially confident in developing nation and best suited for all patients including co-morbidity. PMID:27891393

  5. Mood and psychomotor performance effects of the first, but not of subsequent, cup-of-coffee equivalent doses of caffeine consumed after overnight caffeine abstinence.

    PubMed

    Robelin, M; Rogers, P J

    1998-11-01

    Moderate caffeine consumers (n = 64, mean caffeine intake 453 mg/day) were deprived of caffeine overnight and semi-randomly allocated to four treatment groups, designated PPP, CPP, CCP and CCC, where P is placebo and C is caffeine (1.2 mg/kg, giving an amount of caffeine similar to that consumed in a serving of ground coffee). Caffeine or placebo (i.e. no caffeine) were administered double-blind in novel fruit juice drinks at 10:15, 11:30 and 13:00 h on the test day. Before (baseline), and 45 min after each of these times the participants completed a mood questionnaire and begun psychomotor performance tests lasting 25 min (1-min tapping task, and a long-duration simple reaction time task (SRT). Caffeine significantly increased energetic mood and improved psychomotor performance relative to placebo. Caffeine had particularly marked effects on SRT performance, ameliorating the slowing of performance with time on task and removing the post-lunch dip in performance. However, the three caffeine treatments, CPP, CCP and CCC, were equally effective. That is, mood and performance were improved to the same extent by one, two and three spaced doses (totalling 86, 172 and 258 mg) of caffeine. This result is consistent with previous findings indicating a flat dose-response relationship for the psychoactive effects of caffeine; and because of the adverse effects (e.g. fatigue) associated with overnight caffeine deprivation, it suggests that there is little net benefit to be gained from frequent caffeine use. At the very least, it appears that the psychostimulant effects of caffeine cannot on their own account for the typical pattern of consumption of caffeine-containing drinks.

  6. An online failure detection method of the glucose sensor-insulin pump system: improved overnight safety of type-1 diabetic subjects.

    PubMed

    Facchinetti, Andrea; Del Favero, Simone; Sparacino, Giovanni; Cobelli, Claudio

    2013-02-01

    Sensors for real-time continuous glucose monitoring (CGM) and pumps for continuous subcutaneous insulin infusion (CSII) have opened new scenarios for Type-1 diabetes treatment. However, occasional failures of either CGM or CSII may expose diabetic patients to possibly severe risks, especially overnight (e.g., inappropriate insulin administration). In this contribution, we present a method to detect in real time such failures by simultaneously using CGM and CSII data streams and a black-box model of the glucose-insulin system. First, an individualized state-space model of the glucose-insulin system is identified offline from CGM and CSII data collected during a previous monitoring. Then, this model, CGM and CSII real-time data streams are used online to obtain predictions of future glucose concentrations together with their confidence intervals by exploiting a Kalman filtering approach. If glucose values measured by the CGM sensor are not consistent with the predictions, a failure alert is generated in order to mitigate the risks for patient safety. The method is tested on 100 virtual patients created by using the UVA/Padova Type-1 diabetic simulator. Three different types of failures have been simulated: spike in the CGM profile, loss of sensitivity of glucose sensor, and failure in the pump delivery of insulin. Results show that, in all cases, the method is able to correctly generate alerts, with a very limited number of false negatives and a number of false positives, on average, lower than 10%. The use of the method in three subjects supports the simulation results, demonstrating that the accuracy of the method in generating alerts in presence of failures of the CGM sensor-CSII pump system can significantly improve safety of Type-1 diabetic patients overnight.

  7. The socializing effect of classroom aggression on the development of aggression and social rejection: A two-wave multilevel analysis.

    PubMed

    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.

    This study examined the relationships between personality and aggression using the general aggression (GAM, Anderson and Bushman [2002] Annual Review of Psychology, 53, 27-51) and five factor models (FFMs) (Costa and McCrae [1992] Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI) professional manual. Odessa, FL: Psychological Assessment Resources). Specifically, it examined Ferguson and Dyck's (Ferguson and Dyck [2012] Aggression and Violent Behavior, 17, 220-228) criticisms that the GAM has questionable validity in clinical populations and disproportionately focuses on aggression-related knowledge structures to the detriment of other inputs, specifically personality variables. Fifty-five male offenders attending a community forensic mental health service for pre-sentence psychiatric and/or psychological evaluation were assessed for aggressive script rehearsal, aggression-supportive normative beliefs, FFM personality traits, trait anger and past aggressive behavior. With regard to relationships between five factor variables and aggression, results suggested that only agreeableness and conscientiousness were related to aggression. However, these relationships were: (1) weak in comparison with those between script rehearsal, normative beliefs and trait anger with aggression and (2) were not significant predictors in hierarchical regression analysis when all of the significant univariate predictors, including GAM-specified variables were regressed onto life history of aggression; normative beliefs supporting aggression, aggressive script rehearsal, and trait anger were significantly related to aggression in this regression analysis. These results provide further support for the application of the GAM to aggressive populations.

  9. Toward a nosology of human aggressive behavior.

    1993-01-01

    General attempts have been made to catalog or categorize research literature on aggressive behavior. In the animal literature this category has been delineated by clearly observed and described patterns of behavior. These include offensive and defensive expressions in animals and the characterization of attack behaviors by typography into defensive and offensive. The human literature is considerably deficient in the description and categorization of human aggressive behavior. Current nosologies offer no utilitarian schema for characterizing violent behavior in clinical populations regarding the typography of the violence, its prediction, or guidance as to its treatment. The generation of databased nosologies may provide a mechanism for the development of research and clinically relevant nosologies based upon cluster analyses of treatment outcomes and behavioral characteristics. This strategy may provide a more effective approach for further research concerning clinical aggressive or destructive behaviors.

  10. Human aggression and the lunar synodic cycle.

    Lieber, A L

    1978-05-01

    Data on five aggressive and/or violent human behaviors were examined by computer to determine whether a relationship exists between the lunar syndoic cycle and human aggression. Homicides, suicides, fatal traffic accidents, aggravated assaults and psychiatric emergency room visits occurring in Dade County, Florida all show lunar periodicities. Homicides and aggravated assaults demonstrate statistically significant clustering of cases around full moon. Psychiatric emergency room visits cluster around first quarter and shows a significantly decreased frequency around new and full moon. The suicide curve shows correlations with both aggravated assaults and fatal traffic accidents, suggesting a self-destructive component for each of these behaviors. The existence of a biological rhythm of human aggression which resonates with the lunar synodic cycle is postulated.

  11. Capital, population and urban patterns.

    Zhang, W

    1994-04-01

    The author develops an approach to urban dynamics with endogenous capital and population growth, synthesizing the Alonso location model, the two-sector neoclassical growth model, and endogenous population theory. A dynamic model for an isolated island economy with endogenous capital, population, and residential structure is developed on the basis of Alonso's residential model and the two-sector neoclassical growth model. The model describes the interdependence between residential structure, economic growth, population growth, and economic structure over time and space. It has a unique long-run equilibrium, which may be either stable or unstable, depending upon the population dynamics. Applying the Hopf theorem, the author also shows that when the system is unstable, the economic geography exhibits permanent endogenous oscillations.

    This study focused on verbal and physical aggression against nursing staff, in real time, by elderly patients. The aggressive incidents were recorded at the end of each shift when they were more likely to be accurately remembered. Before beginning the study, nursing staff were taught how to use the Modified Overt Aggression Scale (MOAS) to identify aggressive acts. High rates of verbal and physical aggression among the elderly were observed by nurses, and data show that 75% of nursing staff experienced aggression on their shift. They either experienced aggression themselves or observed aggression on every single shift; that is at least five violent incidents in a work-week. Even if one is not the target of aggression, such observation is associated with elevated levels of stress.

    In 4 experimental studies, we show that customer verbal aggression impaired the cognitive performance of the targets of this aggression. In Study 1, customers' verbal aggression reduced recall of customers' requests. Study 2 extended these findings by showing that customer verbal aggression impaired recognition memory and working memory among employees of a cellular communication provider. In Study 3, the ability to take another's perspective attenuated the negative effects of customer verbal aggression on participants' cognitive performance. Study 4 linked customer verbal aggression to quality of task performance, showing a particularly negative influence of aggressive requests delivered by high-status customers. Together, these studies suggest that the effects of even minor aggression from customers can strongly affect the immediate cognitive performance of customer service employees and reduce their task performance. The implications for research on aggression and for the practice of customer service are discussed.

  14. Predictors of Aggressive Inflammatory Bowel Disease

    Inflammatory bowel disease comprises a group of conditions characterized by idiopathic inflammation of the gastrointestinal tract. The natural course of disease can range from an indolent course with prolonged periods of remission to aggressive, incapacitating disease. Predicting which patients are more susceptible to developing severe disease is important, especially when choosing therapeutic agents and treatment strategies. This paper reviews current evidence on the main demographic, clinical, endoscopic, histologic, serologic, and genetic markers that predict aggressive inflammatory bowel disease. In ulcerative colitis, we considered disease to be aggressive when patients had a high relapse rate, need for admission and/or surgery, development of colon cancer, or extraintestinal manifestations. We defined aggressive Crohn's disease as having a high relapse rate, development of penetrating disease, need for repeat surgery, or multiple admissions for flares. In Crohn's disease, involvement of the upper gastrointestinal tract and ileum, penetrating disease, early age at diagnosis, smoking, extensive ulceration of the mucosa, high titers of serum antibodies, and mutations of the NOD2 gene are markers of aggressive disease. In ulcerative colitis, patients with more extensive involvement of the colon (pancolitis) have more symptomatology and are at higher risk for needing a colectomy and developing colon cancer. Also, plasmocytic infiltration of the colonic mucosa and crypt atrophy predict treatment failure. As with diagnosis, no single method can predict disease aggressiveness. Multiple serologic and genetic tests are being developed to refine the accuracy of prediction. Endoscopic findings can also predict the future course of disease. At present, clinical manifestations are the most useful way to make therapeutic decisions. PMID:22298958

    Research has shown that exposure to violent media increases aggression. However, the neural underpinnings of violent-media-related aggression are poorly understood. Additionally, few experiments have tested hypotheses concerning how to reduce violent-media-related aggression. In this experiment, we focused on a brain area involved in the regulation of aggressive impulses-the right ventrolateral prefrontal cortex (rVLPFC). We tested the hypothesis that brain polarization through anodal transcranial direct current stimulation (tDCS) over rVLPFC reduces aggression related to violent video games. Participants (N = 79) were randomly assigned to play a violent or a nonviolent video game while receiving anodal or sham stimulation. Afterward, participants aggressed against an ostensible partner using the Taylor aggression paradigm (Taylor Journal of Personality, 35, 297-310, 1967), which measures both unprovoked and provoked aggression. Among those who received sham stimulation, unprovoked aggression was significantly higher for violent-game players than for nonviolent-game players. Among those who received anodal stimulation, unprovoked aggression did not differ for violent- and nonviolent-game players. Thus, anodal stimulation reduced unprovoked aggression in violent-game players. No significant effects were found for provoked aggression, suggesting tit-for-tat responding. This experiment sheds light on one possible neural underpinning of violent-media-related aggression-the rVLPFC, a brain area involved in regulating negative feelings and aggressive impulses.

  16. Trait modulation of alcohol-induced laboratory aggression.

    Modest alcohol and aggressive trait effects on laboratory-induced aggression among men have been reported with some consistency in the literature. Relationships between aggressive personality traits and laboratory-induced aggression appear to become less consistent under the influence of alcohol. Several research teams have found suggestions that the effects of alcohol on laboratory aggression may be reduced or even reversed among individuals with aggressive personality traits. This study examined the effects of alcohol on the aggressive responding on the Point Subtraction Aggression Paradigm (PSAP) of eight undergraduate men who generated evidence on the Million Clinical Multiaxial Inventory-II (MCMI-II) of sadistic-aggressive personality disorder features. This sample was compared with a group of 18 undergraduate male peers without MCMI-II elevations described in a previous study. Neither alcohol ingestion (0.8 ml/kg) nor aggressive personality traits predicted laboratory behavior in isolation, but alcohol was found to selectively attenuate (d = 0.75) PSAP responding for the sadistic-aggressive as opposed to the control subjects (i.e., a significant aggressive trait by alcohol interaction). The possible value of this counterintuitive response tendency in identifying men at elevated risk for alcohol-related aggression was discussed. Large, immediate reductions in laboratory-based aggressive responding while under the influence of alcohol might provide a paradoxical high risk indicator that has not been previously identified.

  17. The role of alcohol and steroid hormones in human aggression.

    PubMed

    von der Pahlen, Bettina

    2005-01-01

    The association between alcohol and aggressive behavior is well established although a direct causal relationship has proven hard to demonstrate. There are, however, indications that alcohol facilitates aggression in individuals who already have a predisposition to behave aggressively. Aggressive personality disorders have in turn been explained by elevated testosterone level. A one-to-one relation between increased levels of testosterone and aggression has been, nevertheless, difficult to reveal. Two metabolites of testosterone, estradiol and 5alpha-dihydrotestosterone (DHT), have been studied much less in human aggressive behavior. Estradiol might reduce androgenic effects and have a counterbalancing influence on aggression. DHT, again, has a much higher affinity than testosterone to androgen receptors, and there are indications that some of the effects of testosterone-mediating aggressive behavior occur after aromatization. Disregard of seasonal and circadian fluctuations in male testosterone production might be responsible for some of the inconclusive testosterone-aggression results. In addition, increasing age decreases both aggressive behavior and testosterone production in males. Cortisol has yielded conflicting results as a mediator in aggressive behavior. Both higher and lower levels have been reported in aggressive and abusive men. Finally, the acute and chronic effects of alcohol influence the steroid hormone levels in various ways. The present understanding of the etiology of aggression is still vague. It is clear that a multidimensional approach, combining both biological and psychosocial factors, will be necessary for the development of a more general concept of human aggression in the future.

  18. Siblicidal aggression and resource monopolization in birds.

    PubMed

    1984-08-17

    In Texas, great egret Casmerodius albus chicks attack younger nestmates, often fatally (siblicide). By contrast, the young of neighboring great blue herons Ardea herodias seldom strike or kill siblings. These interspecific differences seem related to prey size: only fish provided by egret parents are small enough for chicks to monopolize (a process facilitated by aggression). Experimentally cross-fostered heron chicks raised on small prey by egret parents became siblicidal, but the reverse procedure of cross-fostering egret chicks did not reduce aggression or siblicide.

    Vertebral hemangiomas are common lesions and usually considered benign. A rare subset of them, however, are characterized by extra-osseous extension, bone expansion, disturbance of blood flow, and occasionally compression fractures and thereby referred to as aggressive hemangiomas. We present a case of a 67-year-old woman with progressive paraplegia and an infiltrative mass of T4 vertebra causing mass effect on the spinal cord. Multiple conventional imaging modalities were utilized to suggest the diagnosis of aggressive hemangioma. Final pathologic diagnosis after decompressive surgery confirmed the diagnosis of an osseous hemangioma.

    Sector of Social Behavior Neurogenetics, Institute of Cytology and Genetics, Siberian Branch, Effects of sodium valproate on the aggressive behavior of male mice with 2- and 20-day positive fighting experience have been studied. It is established that valproate administered in a singe dose of 100 mg/kg has no effect on the behavior of male mice with a 2-day experience of aggression. The treatment of mice with 300 mg/kg of valproate significantly decreased the level of aggressive motivation and the percentage of animals demonstrating attacks and threats. In male mice with a 20-day experience of aggression, valproate decreased the time of hostile behavior in a dose-dependent manner. Valproate in a single dose of 300 mg/kg significantly decreased the level of aggressive motivation, but also produced a toxic effect, whereby 73% of aggressive males demonstrated long-term immobility and 45% exhibited movement abnormalities (falls) upon the treatment. It is suggested that changes in the brain neurochemical activity, which are caused by a prolonged experience of aggression, modify the effects of sodium valproate.

    Oro-facial clefts are one of the most common birth defects and may be associated with other genetic anomalies. Aggressive periodontitis is a rare condition that progresses rapidly, but affects only a small percentage of the population. Most of the cases of aggressive periodontitis are familial. Even though, literature has documented the association of various genetic disorders with aggressive periodontitis, the aggressive periodontitis in patients with isolated cleft lip (CL) have never been addressed. Here, we report a rare case of isolated CL with generalized aggressive periodontitis. The concomitant presentation of isolated CL with aggressive periodontitis in an individual has clinical significance for multi-disciplinary care. PMID:25810600

    Various researchers distinguished two categories of aggressive behaviour, namely reactive and proactive aggression. Reactive aggression is an aggressive response to a perceived threat or provocation, whereas proactive aggression is behaviour that anticipates a reward. In the present study, including both a sample of disruptive behaviour disordered (DBD) and normal control (NC) children, we observed reactive and proactive aggressive behaviour during an experimental dyadic play session. DBD children showed more observed reactive and proactive aggression. Subsequently, we investigated whether the observed measures correlated with parent-rated measures of reactive and proactive aggression in. We distinguished in both NC and DBD children a subgroup showing a rise in cortisol level, i.e. responders, and a subgroup who did not show a rise in cortisol, i.e. non-responders. Results suggest that differences in the cortisol response affects the correspondence between observed and parent-rated reactive and proactive aggression since only DBD non-responders showed the expected correlations.

    2008-10-01

    In introducing this Special Issue on Social Capital and Health, this article tracks the popularization of the term and sheds light on the controversy surrounding the term and its definitions. It sets out four mechanisms that link social capital with health: making information available to community members, impacting social norms, enhancing the health care services and their accessibility in a community, and offering psychosocial support networks. Approaches to the measurement of social capital include the Social Capital Community Benchmark Survey (SCCBS) developed by Robert Putnam, and the Petris Social Capital Index (PSCI), which looks at community voluntary organizations using public data available for the entire United States. The article defines community social capital (CSC) as the extent and density of trust, cooperation, and associational links and activity within a given population. Four articles on CSC are introduced in two categories: those that address behaviors -- particularly utilization of health services and use of tobacco, alcohol, and drugs; and those that look at links between social capital and physical or mental health. Policy implications include: funding and/or tax subsidies that would support the creation of social capital; laws and regulations; and generation of enthusiasm among communities and leaders to develop social capital. The next steps in the research programme are to continue testing the mechanisms; to look for natural experiments; and to find better public policies to foster social capital.

  4. Where's the capital? A geographical essay.

    PubMed

    Jones, Gareth A

    2014-12-01

    This paper is inspired by Thomas Piketty's book Capital in the Twenty-First Century. Piketty does a wonderful job of tracing income and wealth over time, and relating changes to trends of economic and population growth, and drawing out the implications for inequality, inheritance and even democracy. But, he says relatively little about where capital is located, how capital accumulation in one place relies on activities elsewhere, how capital is urbanized with advanced capitalism and what life is like in spaces without capital. This paper asks 'where is the geography in Capital' or 'where is the geography of capital in Capital'? Following Piketty's lead, the paper develops its analysis through a number of important novels. It examines, first, the debate that Jane Austen ignored colonialism and slavery in her treatment of nineteenth century Britain, second, how Balzac and then Zola provide insight to the urban political economy of capital later in the century, and third, how Katherine Boo attends to inequality as the everyday suffering of the poor.

    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.

    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 focus of this article is on the examination of variables that moderate the influence of exposure to TV violence. The research on the relationship between TV violence and aggressive behavior of the audience has largely focused on addressing the social policy issue of whether witnessing TV violence fosters aggressive behavior in viewers, particularly children. There has been a dearth of research addressing the conditions that enhance the aggression stimulating effects of media violence, those that mitigate these effects, and those that may even result in reduced aggression after one witnesses media violence. To illustrate the importance of potential moderating factors, we present longitudinal correlational data relating the degree of viewing TV violence to various social behaviors and cognitive attributes of White and African-American male and female elementary-school-age children. Although TV violence viewing was associated with lower cognitive attributes and negative social behaviors in White males and females and African-American females, a very different pattern of relationships was found for African-American males.

  4. Modeling aggressive driver behavior at unsignalized intersections.

    PubMed

    Kaysi, Isam A; Abbany, Ali S

    2007-07-01

    The processing of vehicles at unsignalized intersections is a complex and highly interactive process, whereby each driver makes individual decisions about when, where, and how to complete the required maneuver, subject to his perceptions of distances, velocities, and own car's performance. Typically, the performance of priority-unsignalized intersections has been modeled with probabilistic approaches that consider the distribution of gaps in the major-traffic stream and their acceptance by the drivers of minor street vehicles based on the driver's "critical gap". This paper investigates the aggressive behavior of minor street vehicles at intersections that are priority-unsignalized but operate with little respect of control measures. The objective is to formulate a behavioral model that predicts the probability that a driver performs an aggressive maneuver as a function of a set of driver and traffic attributes. Parameters that were tested and modeled include driver characteristics (gender and age), car characteristics (performance and model year), and traffic attributes (number of rejected gaps, total waiting time at head of queue, and major-traffic speed). Binary probit models are developed and tested, based on a collected data set from an unsignalized intersection in the city of Beirut, to determine which of the studied variables are statistically significant in determining the aggressiveness of a specific driver. Primary conclusions reveal that age, car performance, and average speed on the major road are the major determinants of aggressive behavior. Another striking conclusion is that the total waiting time of the driver while waiting for an acceptable gap is of little significance in incurring the "forcing" behavior. The obtained model is incorporated in a simple simulation framework that reflects driver behavior and traffic stream interactions in estimating delay and conflict measures at unsignalized intersections. The simulation results were then compared

    The burgeoning interest in social capital within the technology community represents a welcome move towards a concern for the social elements of technological adaptation and capacity. Since technology plays an ever larger role in our daily life, it is necessary to articulate social capital and its relationship to technological literacy. A nationwide data was collected by area sampling, and position generator was used to measure social capital. Regression model was constructed for technological literacy. Age, gender, education, income, web access, and social capital were included as independent variables. The results show that age, gender, education, web access, and social capital were good predictors of technological literacy. It is concluded that social capital is helpful in coping with rapid technological change. Theoretical and empirical implications and future research are discussed. PMID:22619593

    Aggressive behavior is a common problem among children with autism spectrum disorder (ASD) and could negatively affect family functioning and school and social competence. The aim of the present study was to investigate the relationship between aggressive behavior, such as self-aggression and other-aggression, with verbal communication ability and IQ level in children with ASD. The sample examined in this study included 88 children with a diagnosis of ASD. For the purposes of our study, much attention was focused on individual items of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview–Revised that were useful to evaluate the aggressive behavior. We have not found any association between aggressive behavior (other-aggression and self-aggression) and the absence of language or low IQ in children with ASD. Thus, the degree of severity of autism is probably the most important risk factor for this behavior. PMID:27336016

    Mothers in numerous species exhibit heightened aggression in defense of their young. This shift typically coincides with the duration of lactation in nonhuman mammals, which suggests that human mothers may display similarly accentuated aggressiveness while breast feeding. Here we report the first behavioral evidence for heightened aggression in lactating humans. Breast-feeding mothers inflicted louder and longer punitive sound bursts on unduly aggressive confederates than did formula-feeding mothers or women who had never been pregnant. Maternal aggression in other mammals is thought to be facilitated by the buffering effect of lactation on stress responses. Consistent with the animal literature, our results showed that while lactating women were aggressing, they exhibited lower systolic blood pressure than did formula-feeding or never-pregnant women while they were aggressing. Mediation analyses indicated that reduced arousal during lactation may disinhibit female aggression. Together, our results highlight the contributions of breast feeding to both protecting infants and buffering maternal stress.

    Appetitive aggression refers to positive feelings being associated with the perpetration of violent behavior and has been shown to provide resilience against the development of PTSD in combatants returning from the battlefield. Until this point, appetitive aggression has been primarily researched in males. This study investigates appetitive aggression in females. Female and male combatants and civilians from Burundi were assessed for levels of appetitive aggression. In contrast to non-combatants, no sex difference in appetitive aggression could be detected for combatants. Furthermore, each of the female and male combatant groups displayed substantially higher levels of appetitive aggression than each of the male and female civilian control groups. This study demonstrates that in violent contexts, such as armed conflict, in which individuals perpetrate numerous aggressive acts against others, the likelihood for an experience of appetitive aggression increases- regardless of whether the individuals are male or female.

    The present study examined specialized associations between parental control and child aggression in a sample of 600 8- to 10-years old children. Parental control dimensions and aggression subtypes were assessed using multiple informants (i.e. children, mothers, fathers, peers, and teachers). In line with expectations, parental physical punishment was positively associated with overt aggression, whereas parental psychological control was positively associated with relational aggression in both girls and boys. In addition, this study demonstrated that if both parents employed similar parenting strategies, it appeared to have a cumulative effect on child aggressive behaviour. Associations involving overt aggression were more pronounced for boys than girls, whereas associations involving relational aggression were not moderated by gender. Overall, the present study contributes to an emerging research field by supporting the hypothesis of specialized associations between parental control and child aggression.

    2016-01-01

    The present study examined relationships between three key executive functions (working memory, inhibition, and mental set-shifting) and multiple types of aggression in a general population sample of 9-year-old children. One hundred and forty-eight children completed a battery of executive function tasks and were rated on aggression by their primary teachers. All executive function (EF) composites were related to a composite measure of aggression. Working memory (WM) was most consistently related to the different types of aggression (overt, relational, reactive, and proactive), whereas inhibition and mental set-shifting only were related to relational and reactive aggression, respectively. Specificity in relations (studied as independent contributions) was generally low with the exception of the relation between WM and relational aggression. Taken together, our results highlight the roles of WM and relational aggression in EF-aggression relations in middle childhood.

    Neighborhood characteristics have been shown to impact child well-being. However, it remains unclear how these factors combine with family characteristics to influence child development. The current study helps develop that understanding by investigating how neighborhoods directly impact child and adolescent behavior problems as well as moderate the influence of family characteristics on behavior. Using multilevel linear models, we examined the relationship among neighborhood conditions (poverty and social capital) and maternal depression on child and adolescent behavior problems. The sample included 741 children, age 5–11, and 564 adolescents, age 12–17. Outcomes were internalizing (e.g. anxious/depressed) and externalizing (e.g. aggressive/hyperactive) behavior problems. Neighborhood poverty and maternal depression were both positively associated with behavior problems for children and adolescents. However, while neighborhood social capital was not directly associated with behavior problems, the interaction of social capital and maternal depression was significantly related to behavior problems for adolescents. This interaction showed that living in neighborhoods with higher levels of social capital attenuated the relationship between maternal depression and adolescent behavior problems and confirmed the expectation that raising healthy well-adjusted children depends not only on the family, but also the context in which the family lives.

    This study examined aggressive and pro-social classroom descriptive norms as predictors of change in aggression and victimization during middle childhood. Participants included 948 children in third through fifth grade. Measures of teacher-reported aggressive and peer-reported pro-social descriptive norms were completed at the onset of the study. Children completed self-report measures of aggression and victimization on three occasions during one academic year. Multilevel growth models were analyzed to determine the amount of student-reported change in aggression and victimization attributable to the classroom norm variables. Results indicated that students in classrooms with higher initial mean levels of aggression reported larger increases in aggression and victimization over the school year. In contrast, boys with higher initial levels of aggression reported smaller increases in aggression than boys with lower initial levels of aggression, and both boys and girls with higher initial aggression reported declining victimization over the school year. Pro-social classroom norms were unrelated to change in aggression and victimization. The implications of the findings for future studies on the influence of classroom social norms as well as interventions for aggression and victimization are discussed.

  17. Piketty's capital and social policy.

    PubMed

    Piachaud, David

    2014-12-01

    Piketty's Capital (2014) primarily describes and analyses changes in the distribution of wealth and annual incomes. This paper focuses on his policy proposals that make up Part Four of the book. Piketty defends the 'social state' but he discusses it largely in terms of distribution and redistribution between tax units. This neglects the important role of social policy in promoting recognition and redistribution of income and opportunities that is related to gender, race, disability and sexual orientation. Nor does Piketty consider inequalities in health which effect life-time incomes, nor the impact of housing policies on house prices and the distribution of wealth. It is argued that Piketty's approach to social security is simplistic and plays down the complexity of competing policy goals. On taxation, Piketty defends progressive taxation and proposes a global capital levy. The latter proposal runs into formidable problems in seeking global taxation in a world of nation states. Rather than seeking a policy that is, for the foreseeable future, wholly politically impractical, a case is made for less idealistic but more practical and urgent tax coordination between nations to address the widespread avoidance of taxation that large corporations and the very wealthy are now permitted - taxation on which the future of the social state depends. The importance of human and social capital, which are largely set aside by Piketty, are discussed. Finally,it is argued that his approach to policy is to describe trends and propose amelioration of growing inequality rather than to identify causes of the trends and propose policies that might address the causes. Nevertheless, the importance of his work in bringing issues of inequality to the fore, especially among economists, is recognized and applauded.

    As consumers continue to demand the most advanced technology at the lowest cost, healthcare organizations are turning to leasing as a way of acquiring equipment with a minimum amount of capital investment. Institutions considering leasing should determine their balance sheet constraints, compare the relative costs of debt financing and leasing, and assess the residual value of the equipment at the end of its use. Comparing potential lessors requires careful analysis of rate structures and the capability of the companies to commit to a contract promptly.

For the United States, the author focuses on Robert Putnam's understanding of both concepts, showing that the apolitical analysis of the Progressive Era, of the progressive developments in Northern Italy, and of the situation of labor unions in the United States is not only insufficient but wrong. The critique also includes the difference between U.S. communitarianism and its European versions, Christian democracy and New Labour, and the limitations of both approaches. The uses and misuses of these concepts in the political debate are discussed.

    Theories and measures of women's aggression in intimate relationships are only beginning to be developed. This study provides a first step in conceptualizing the measurement of women's aggression by examining how well three widely used measures (i.e., the Revised Conflict Tactics Scales (CTS), the Sexual Experiences Survey [SES], and the Psychological Maltreatment of Women Inventory [PMWI]) perform in assessing women's perpetration of and victimization by aggression in their intimate relationships with men. These constructs were examined in a diverse sample of 412 African American, Latina, and White women who had all recently used physical aggression against a male intimate partner. The factor structures and psychometric properties of perpetration and victimization models using these measures were compared. Results indicate that the factor structure of women's perpetration differs from that of women's victimization in theoretically meaningful ways. In the victimization model, all factors performed well in contributing to the measurement of the latent victimization construct. In contrast, the perpetration model performed well in assessing women's physical and psychological aggression but performed poorly in assessing women's sexual aggression, coercive control, and jealous monitoring. Findings suggest that the power and control model of intimate partner violence (IPV) may apply well to women's victimization but not as well to their perpetration of violence.

    A cross-sectional study was performed in order to examine the association between canine aggression to familiar people and serum concentrations of total thyroxine (TT4), free thyroxine (fT4), thyroxine autoantibodies (T4AA), total triiodothyronine (TT3), free triiodothyronine (fT3), triiodothyronine autoantibodies (T3AA), thyroid stimulating hormone (TSH), and thyroglobulin autoantibodies (TgAA). The subjects were 31 dogs historically aggressive to familiar people and 31 dogs with no history of aggression. Behavioral evaluation and physical examination were completed for each dog in addition to a complete blood count, serum chemistry panel, TT4, fT4 by equilibrium dialysis, TT3, fT3, TgAA, T3AA, and T4AA. Significant differences were found between the two groups with respect to only T4AA, which was increased in the aggressive group, but the concentrations for both groups were within the normal reference range. There were no differences between the two groups in the thyroid analytes most commonly measured by veterinary practitioners evaluating thyroid function in dogs. The results of this study revealed no significant difference between aggressive and non-aggressive dogs in the thyroid concentrations most commonly used to diagnose canine hypothyroidism.

    With operating margins showing some improvement in 2003, Y2K being a distant memory, and many critical capital investment decisions delayed as long as possible, hospitals have been on a relative spending spree, building new facilities, renovating operating rooms and inpatient units, and investing in new medical and information technologies. However, with pressure on both cost and revenue expected to continue, if not increase, this spending spree may be short-lived, and hospitals must improve their capital planning efforts; align them with their mission, vision, and strategies; and ensure that capital is available when unplanned or even expected needs arise. This article explores some of the challenges that hospitals face in their capital planning efforts and, more importantly, suggests the necessity for hospitals to integrate capital and strategic planning. Capital planning must be driven by an organization's strategies; however, we also argue that an organization's ability to execute its strategies is highly dependent on the existence of a cohesive capital prioritization and planning process. In this article, we explore a number of issues critical to developing a comprehensive capital plan, including estimating capital costs, evaluating and designing strategies to contend with risk, saving for the proverbial "rainy day," and recognizing the role and value of philanthropy, while challenging some conventional thinking of hospital executives with respect to investment, growth, and planning.

    2015-02-01

    Lateralisation (i.e. different functional and/or structural specialisations of the left and right sides of the brain) of aggression has been examined in several vertebrate species, while evidence for invertebrates is scarce. In this study, we investigated lateralisation of aggressive displays (boxing with forelegs and wing strikes) in the Mediterranean fruit fly, Ceratitis capitata. We attempted to answer the following questions: (1) do medflies show lateralisation of aggressive displays at the population-level; (2) are there sex differences in lateralisation of aggressive displays; and (3) does lateralisation of aggression enhance fighting success? Results showed left-biased population-level lateralisation of aggressive displays, with no consistent differences among sexes. In both male-male and female-female conflicts, aggressive behaviours performed with left body parts led to greater fighting success than those performed with right body parts. As we found left-biased preferential use of body parts for both wing strikes and boxing, we predicted that the left foreleg/wing is quicker in exploring/striking than the right one. We characterised wing strike and boxing using high-speed videos, calculating mean velocity of aggressive displays. For both sexes, aggressive displays that led to success were faster than unsuccessful ones. However, left wing/legs were not faster than right ones while performing aggressive acts. Further research is needed on proximate causes allowing enhanced fighting success of lateralised aggressive behaviour. This is the first report supporting the adaptive role of lateralisation of aggressive displays in insects.

    Accurately predicting inpatient aggression is an important endeavor. The current study investigated inpatient aggression over a six-month time period in a sample of 152 male forensic patients. We assessed constructs of psychopathy, anger, and active symptoms of mental illness and tested their ability to predict reactive and instrumental aggression. Across all levels of analyses, anger and active symptoms of mental illness predicted reactive aggression. Traits of psychopathy, which demonstrated no relationship to reactive aggression, were a robust predictor of instrumental aggression. This study (a) reestablishes psychopathy as a clinically useful construct in predicting inpatient instrumental aggression, (b) provides some validation for the reactive/instrumental aggression paradigm in forensic inpatients, and (c) makes recommendations for integrating risk assessment results into treatment interventions.

  6. Partner aggression among men and women in substance use disorder treatment: correlates of psychological and physical aggression and injury.

    PubMed

    Chermack, Stephen T; Murray, Regan L; Walton, Maureen A; Booth, Brenda A; Wryobeck, John; Blow, Frederic C

    2008-11-01

    This study examined intimate partner aggression in a sample of 489 participants enrolled in substance use disorder treatment, and expands on prior research by including measures of various forms of aggression, a mixed gender sample (76% men, 24% women), and measurement of several potential risk domains. Aggression measures included both participant-partner and partner-to-participant psychological aggression, physical aggression and injury. Analyses focused on the role of distal and proximal risk factors, including demographics, history of childhood physical and sexual abuse, and family history of problems with alcohol, drugs and depression, as well as recent substance use and symptoms of depression. Overall rates of participant-partner psychological aggression (77%), physical aggression (54%) and injuring partners (33%) were high, as were rates of partner-to-participant psychological aggression (73%), physical aggression (51%), and injury (33%). Several distal (family history variables, physical abuse) and proximal factors (binge drinking, several different drugs, depressive symptoms) were bivariately related to most of the aggression measures. However, according to multivariate analyses predicting aggression and injury measures, binge drinking and cocaine use were the drugs significantly associated with most measures, depression symptoms also were related to most aggression and injury measures, and a history of reported childhood physical abuse was related to all frequency of aggression and injury measures among those reporting such behaviors. Overall, the high rates of aggression among both men and women observed in this study further illustrate the need for interventions targeting substance use and aggression, and for further research regarding the inter-relationships among substance, aggression and depressive symptoms.

  8. Differences in Dry Eye Questionnaire Symptoms in Two Different Modalities of Contact Lens Wear: Silicone-Hydrogel in Daily Wear Basis and Overnight Orthokeratology

    PubMed Central

    Rico-del-Viejo, Laura; Martin-Gil, Alba

    2016-01-01

    Purpose. To compare the ocular surface symptoms and signs in an adult population of silicone-hydrogel (Si-Hy) contact lens (CL) wearers with another modality of CL wear, overnight orthokeratology (OK). Materials and Methods. This was a prospective and comparative study in which 31 myopic subjects were fitted with the same Si-Hy CL and 23 underwent OK treatment for 3 months. Dry eye questionnaire (DEQ) was filled in at the beginning of the study and then after 15 days, 1 month, and 3 months using each CL modality. The tear quality was evaluated with noninvasive tear break-up time. Tear production was measured with Schirmer test. Tear samples were collected with Schirmer strips being frozen to analyze the dinucleotide diadenosine tetraphosphate (Ap4A) concentration with High-Performance Liquid Chromatography (HPLC). Results. After refitting with ortho-k, a reduction in discomfort and dryness symptoms at the end of the day (p < 0.05, χ2) was observed. No significant changes were observed in Ap4A concentration in any group. Bulbar redness, limbal redness, and conjunctival staining increased significantly in the Si-Hy group (p < 0.05, Kruskal–Wallis test). Conclusion. Discomfort and dryness symptoms at the end of the day are lower in the OK CL group than in the Si-Hy CL group. PMID:27689073

  10. Aggression Norms in the Classroom Social Network: Contexts of Aggressive Behavior and Social Preference in Middle Childhood.

    PubMed

    Jackson, Daisy R; Cappella, Elise; Neal, Jennifer Watling

    2015-12-01

    In a cross-sectional sample of African-American 2nd-4th grade students (N = 681), we examine the moderating effects of classroom overt and relational aggression norms on peers' social acceptance of classmates who exhibit overt and relational aggression in urban schools. Extending theory and research on classroom norms, we integrate social network data to adjust aggression norms based on children's direct and indirect connections in the classroom. Results of multilevel models indicate that network-based classroom aggression norms moderated relations between children's aggressive behavior and their social preference. Specifically, children benefited socially when their form of aggressive behavior fit with what was normative in the classroom social context. The moderating effect of classroom aggression norms was stronger for the association between overt aggression and social preference than relational aggression and social preference. Relationally aggressive youth were socially preferred by peers regardless of the classroom norm, although this positive association was magnified in classrooms with higher levels of relational aggression. Future research focused on aggression norms within classroom social networks are discussed and implications for school prevention efforts are considered.

  11. Workplace victimization: aggression from the target's perspective.

    PubMed

    Aquino, Karl; Thau, Stefan

    2009-01-01

    This article reviews research on workplace victimization, which we define as acts of aggression perpetrated by one or more members of an organization that cause psychological, emotional, or physical harm to their intended target. We compare several types of victimizing behaviors that have been introduced into the organizational psychology literature to illustrate differences and similarities among them. We then review studies looking at who is likely to become a victim of aggression. Predictors include personality, demographic, behavioral, structural, and organizational variables. We also review research on coping strategies for victimization, which include problem-focused and emotion-focused strategies. We conclude with a summary of challenges for victimization research. These include addressing the proliferation of constructs and terms into the literature, attempting to clarify inconclusive findings, and using theory to guide the selection of study variables.

  12. The impact of social desirability on psychometric measures of aggression.

    PubMed

    Vigil-Colet, Andreu; Ruiz-Pamies, Mireia; Anguiano-Carrasco, Cristina; Lorenzo-Seva, Urbano

    2012-05-01

    Although many studies have focused on the effects of social desirability in personality measures, few have analysed its effects on such highly undesirable behaviour as aggressiveness. The present study analyzes the impact of social desirability on measures of direct and indirect aggression and on the relationships between both kinds of aggression with impulsivity, using a method that enables the content factors of the measures to be isolated from social desirability. Results showed that aggression measures are highly affected by social desirability and that the relationships between the two forms of aggression and impulsivity are due to the content measured by the tests and not to a common social desirability factor.

  13. Psychotherapeutic approaches to aggressive and violent patients.

    PubMed

    Alpert, J E; Spillmann, M K

    1997-06-01

    Behavioral and cognitive-behavioral strategies and a broad range of group, family, couples, and milieu treatment approaches have been developed for the psychotherapy of aggressive and violent patients. These methods have been carried out in diverse settings ranging from hospitals and prisons to individual outpatient practices and have been applied across diverse populations including adults with mental retardation, dementia, and brain injury; children with attention deficit and conduct disorders and autism; recurrent violent offenders with antisocial personality disorder; and individuals with chronic psychotic disorders, mood disorders, or medical illnesses such as hypertension. Bridging these different strategies are the underlying principles of psychotherapy with aggressive and violent patients. These include ensuring the safety of clinician, patient, and potential victims as the foremost concern; developing a finely detailed assessment of aggressive and violent acts and of the antecedents, assumptions, and consequences that are attached to them; formulating well-defined goals and striving for clear communication to achieve consistency in the pursuit of these goals between therapist and patient, and among therapist and other clinicians, staff, and relevant family members or agencies; specifying ahead of time well-considered outcome measures to be used to gauge the effectiveness of treatment; and maintaining a healthy vigilance for countertransferential and similar reactions and a willingness to use consultation as an integral part of treatment.

  14. The evolution of humor from male aggression

    PubMed Central

    Shuster, Sam

    2012-01-01

    The response to seeing a man riding a unicycle was reported to be consistently related to the viewer’s sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15–69 years, with 2–40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection. PMID:22359467

  15. Preemptive strikes: Fear, hope, and defensive aggression.

    PubMed

    Halevy, Nir

    2017-02-01

    Preemptive strikes are costly and harmful. Existing models of defensive aggression focus narrowly on the role fear plays in motivating preemptive strikes. Theoretically integrating the literatures on conflict, decision making, and emotion, the current research investigated how specific emotions associated with certainty or uncertainty, including fear, anger, disgust, hope, and happiness, influence preemptive strikes. Study 1 demonstrated that hope negatively predicts defensive exits from relationships in choice dilemmas. Studies 2 and 3 experimentally manipulated risk of being attacked in an incentivized, interactive decision making task-the Preemptive Strike Game. Risk of being attacked fueled preemptive strikes; reduced feelings of hope partially mediated this effect in Study 3. Studies 4 and 5 investigated preemptive strikes under uncertainty (rather than risk). In Study 4, reasoning about the factors that make one trustful of others curbed preemptive strikes; cogitating about the factors that underlie discrete emotions, however, did not influence defensive aggression. Study 5 demonstrated that the valence and uncertainty appraisals of incidental emotions interact in shaping preemptive strikes. Specifically, recalling an autobiographical emotional experience that produced hope significantly decreased attack rates relative to fear, happiness, and a control condition. Fear, anger, disgust, and happiness were either unrelated to preemptive strikes or showed inconsistent relationships with preemptive strikes across the 5 studies. These findings shed light on how emotions shape defensive aggression, advance knowledge on strategic choice under risk and uncertainty, and demonstrate hope's positive effects on social interactions and relationships.

  16. Racial disparity in capital punishment and its impact on family members of capital defendants.

    PubMed

    Schweizer, Jennifer

    2013-01-01

    A review of the literature was conducted to explore the continuing racial disparity in capital punishment and its effects on family members of African American capital defendants. Statistical studies conducted on both the state and national level conclude that racial bias influences all stages of the death penalty process, with race of the victim being one of the most significant factors. This racial bias places an added burden on family members of African American capital defendants. While research has explored the impact of capital punishment on family members of capital defendants, the unique experiences of family members of African American defendants has not been addressed in the research literature.

  17. Patient characteristics associated with aggression in mental health units.

    PubMed

    Podubinski, Tegan; Lee, Stuart; Hollander, Yitzchak; Daffern, Michael

    2017-04-01

    Aggression in mental health units is a significant and pervasive problem. However, the characteristics of patients associated with increased aggression propensity remain unclear and there are few attempts to expand understanding of these characteristics by drawing upon contemporary aggression theory. This study assessed the influence of interpersonal (hostile-dominance) and personality (psychopathy), General Aggression Model-specified (aggressive script rehearsal, attitudes towards violence, and trait anger), and clinical (psychiatric symptoms) factors on aggression during psychiatric hospitalization in 200 inpatients (132 men and 68 women; 19-64 years, M=38.32 years, S.D.=11.13 years). Patient characteristics were assessed on admission using structured interviews and self-report psychological tests. Patients' files were reviewed and nurses were interviewed after patients were discharged to establish whether patients were aggressive during their hospital stay. Results of univariate analyses showed that higher levels of interpersonal hostile-dominance, psychopathy and aggressive script rehearsal, positive attitudes towards violence, trait anger, and disorganized and excited type psychiatric symptoms all predicted aggression. In the final multivariable logistic regression model, only hostile-dominance remained as a significant predictor of aggressive behavior. This important personality characteristic should be considered in violence risk assessments and aggression prevention strategies.

  18. The Social Values of Aggressive-Prosocial Youth.

    PubMed

    McDonald, Kristina L; Benish-Weisman, Maya; O'Brien, Christopher T; Ungvary, Stephen

    2015-12-01

    Recent research has identified youth who utilize both aggressive and prosocial behavior with peers. Although the social values and motivations associated with aggression and prosocial behavior have been well studied, the values of youth who utilize both aggression and prosocial behavior are unknown. The current study identified groups of adolescents based on peer nominations of aggression and prosocial behavior from both Israel (n = 569; 56.94% Arab, 43.06% Jewish; 53.78% female) and the United States (n = 342; 67.54% African-American; 32.46% European-American; 50.88% female). Self-enhancement, self-transcendence, openness-to-change, and conservation values predicted behavioral group membership. Power values predicted membership in the aggressive group relative to the aggressive-prosocial, prosocial, and low-both groups. For Israeli boys, openness-to-change values predicted membership in the aggressive-prosocial group relative to the prosocial group. The values of aggressive-prosocial youth were more similar to the values of prosocial peers than to aggressive peers, suggesting that motivational interventions for aggressive-prosocial youth should differ in important ways than those for aggressive youth.

  19. Neural mediators of the intergenerational transmission of family aggression.

    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.

  20. Reducing proactive aggression through non-invasive brain stimulation.

    2015-10-01

    Aggressive behavior poses a threat to human collaboration and social safety. It is of utmost importance to identify the functional mechanisms underlying aggression and to develop potential interventions capable of reducing dysfunctional aggressive behavior already at a brain level. We here experimentally shifted fronto-cortical asymmetry to manipulate the underlying motivational emotional states in both male and female participants while assessing the behavioral effects on proactive and reactive aggression. Thirty-two healthy volunteers received either anodal transcranial direct current stimulation to increase neural activity within right dorsolateral prefrontal cortex, or sham stimulation. Aggressive behavior was measured with the Taylor Aggression Paradigm. We revealed a general gender effect, showing that men displayed more behavioral aggression than women. After the induction of right fronto-hemispheric dominance, proactive aggression was reduced in men. This study demonstrates that non-invasive brain stimulation can reduce aggression in men. This is a relevant and promising step to better understand how cortical brain states connect to impulsive actions and to examine the causal role of the prefrontal cortex in aggression. Ultimately, such findings could help to examine whether the brain can be a direct target for potential supportive interventions in clinical settings dealing with overly aggressive patients and/or violent offenders.
