The authors examined the hypothesized influence of maternal and paternal hostility on youth delinquency over time. The investigation addressed significant gaps in earlier research on parental hostility, including the neglect of father effects, especially in African American families. Using prospective, longitudinal data from community samples of European American (n = 422) and African American (n = 272) 2-parent families, the authors examined the independent effects of paternal and maternal hostility on youth delinquency. The results indicated that paternal hostility significantly predicted relative increases in youth delinquent behaviors above and beyond the effects of maternal hostility; conversely, maternal hostility did not predict youth delinquency after controlling for paternal hostility. Multiple-group analyses yielded similar results for both ethnic groups and for boys and girls. These results underscore the importance of including both parents in research on diverse families. Neglecting fathers provides an incomplete account of parenting in relation to youth development.

Psychosocial antecedents of hostility in persons with coronary heart disease.

Sofhauser, Cynthia D

2003-09-01

Although it is known that hostility precedes coronary heart disease (CHD), little is known about factors that influence the development and progression of hostile characteristics. The relations among hostility, self-esteem, self-concept, and psychosocial residual were conceptualized within the modeling and role-modeling theoretical framework and examined in a sample of 85 persons with CHD. There were significant associations between all variables. Regression analyses revealed that self-esteem, mistrust residual, isolation residual, and self-concept contributed significantly, accounting for 31% of the variation in hostility scores. These findings provide support for the belief that the development of hostility in persons with CHD is related to beliefs and attitudes about the self and others. Persons with self-esteem need deficits, and a subsequent build up of negative psychosocial residual, have poor self-concepts. This poor self-concept is hostile in nature and reflects a mistrust of others and a deep sense of isolation.

Invention of a tunable damper for use with an acoustic waveguide in hostile environments

International Nuclear Information System (INIS)

Rogers, S.C.

1984-06-01

A damper was invented to remove undesirable stress pulses from an acoustic waveguide. Designed to be tunable, the damper was constructed to withstand a corrosive or otherwise hostile environment. It serves to simplify the design and enhance the performance of a water-level measurement system, of which the damper and acoustic waveguide are integral parts. An experimental damper was constructed and applied to an existing level probe and measurement system. The resulting damper, properly tuned, causes acoustic stress pulses that pass into it along the waveguide to be attenuated

Hostile reconnaissance is vital to successful terrorist activity. Individuals carrying out this activity are likely to experience raised levels of stress and this will manifest itself at biological, physiological, psychological and behavioural levels, providing an opportunity for detection. A field trial was undertaken in an ecologically valid environment measuring variables considered likely to be salient during hostile intent. The parameters examined in the field trial varied in a predictable manner and suggest that stressed individuals secrete a volatile steroid based marker that could form the basis for remote detection. Thus, overall the findings of this research provide a validated model of hostile intent that can be used by other researchers to test interventions aimed at detecting or deterring hostile intent.

Temperature-compensated pressure detectors and transmitter for use in hostile environment

International Nuclear Information System (INIS)

Di Noia, E.J.; Breunich, T.R.

1984-01-01

A pressure or differential pressure detector suitable for use in a hostile environment, for example, under high pressure, temperature, and radiation conditions in the containment vessel of a nuclear generating plant includes as a transducer a linear variable differential transformer (LVDT) disposed within a detector housing designed to withstand temperatures of about 260 deg C. A signal detecting and conditioning circuit remote from the detector housing includes a demodulator for producing X and Y demodulated signals respectively from A and B secondary windings of the LVDT, a summing circuit for producing a temperature analog voltage X + Y, a subtractor for providing a differential pressure analog voltage X - Y, and a multiplier for multiplying the differential pressure analog voltage X - Y by a temperature compensation voltage X + Y - Ref based on the temperature analog voltage to provide a resulting temperature-compensated differential pressure analog signal.

Emergence of microbial networks as response to hostile environments

Directory of Open Access Journals (Sweden)

Dario eMadeo

2014-08-01

Full Text Available The majority of microorganisms live in complex communities under varying conditions. One pivotal question in evolutionary biology is the emergence of cooperative traits and their sustainment in altered environments or in the presence of free-riders. Co-occurrence patterns in the spatial distribution of biofilms can help define species' identities, and systems biology tools are revealing networks of interacting microorganisms. However, networks of inter-dependencies involving micro-organisms in the planktonic phase may be just as important, with the added complexity that they are not bounded in space. An integrated approach linking imaging, ``Omics'' and modeling has the potential to enable new hypothesis and working models. In order to understand how cooperation can emerge and be maintained without abilities like memory or recognition we use evolutionary game theory as the natural framework to model cell-cell interactions arising from evolutive decisions. We consider a finite population distributed in a spatial domain (biofilm, and divided into two interacting classes with different traits. This interaction can be weighted by distance, and produces physical connections between two elements allowing them to exchange finite amounts of energy and matter. Available strategies to each individual of one class in the population are the propensities or ``willingness'' to connect any individual of the other class. Following evolutionary game theory, we propose a mathematical model which explains the patterns of connections which emerge when individuals are able to find connection strategies that asymptotically optimize their fitness. The process explains the formation of a network for efficiently exchanging energy and matter among individuals and thus ensuring their survival in hostile environments.

2011-10-01

Hostile behaviour is becoming a way of life in South Africa. Hostility prevails at all settings, including in the health sector. In a forensic ward psychiatric nurses are subjected to hostile behaviour by the patients. The aim of the present study was to explore and describe the psychiatric nurses' experiences of hostile behaviour by patients in a forensic ward and make recommendations for nurse managers to empower these psychiatric nurses to cope with the patients' aggression. Qualitative, in-depth, phenomenological interviews were conducted with nine psychiatric nurses exposed to hostility from patients in a forensic ward. Recommendations were derived from the results from nurse managers to assist psychiatric nurses. It became apparent from the findings that psychiatric nurses in a forensic ward work in a stressful environment. Hostile behaviour in the forensic ward is consistently experienced by the psychiatric nurses as hindering therapeutic relationships. The psychiatric nurses experienced being disempowered. Psychiatric nurses experience hostile behaviour by patients in a forensic ward as disempowering. IMPLICATIONS FOR NURSE MANAGEMENT: Nurse managers can facilitate psychiatric nurses' empowerment by providing them access to: information, support, resources, opportunity and growth. © 2011 Blackwell Publishing Ltd.

Hostility and hearing protection behavior: the mediating role of personal beliefs and low frustration tolerance.

Science.gov (United States)

Rabinowitz, S; Melamed, S; Feiner, M; Weisberg, E; Ribak, J

1996-10-01

The authors examined whether hostility would negatively be associated with occupational health behavior, namely, the use of hearing protection devices (HPDs). Also examined as possible mediators were the protection motivation theory (PMT) components and low frustration tolerance (LFT). Participants were 226 male industrial workers, all exposed to potentially hearing-damaging noise. Hostility was negatively related to HPD use. It moderately correlated with the PMT components: negatively with perceived susceptibility, severity, effectiveness, and self-efficacy and positively with perceived barriers. Hostility correlated highly with LFT. Regression analyses confirmed the mediating role of perceived barriers, low self-efficacy, and LFT in the negative relationship between hostility and the use of HPDs. Thus, intrapsychic characteristics of hostile people may be significant for hearing protection behavior.

Muris, Peter; Meesters, Cor; Morren, Mattijn; Moorman, Lidwine

2004-09-01

To examine relationships between self-reported attachment style and parental rearing behaviors, on the one hand, and anger/hostility, on the other hand, in a sample of nonclinical adolescents (N=441). Participants completed (a) a single-item measure of attachment style; (b) a questionnaire measuring perceptions of parental rearing behaviors; and (c) two scales assessing anger and hostility. Self-reported attachment style was related to anger/hostility. That is, adolescents who defined themselves as avoidantly or ambivalently attached displayed higher levels of anger/hostility than adolescents who classified themselves as securely attached. Furthermore, perceived parental rearing was also related to anger/hostility. More specifically, low levels of emotional warmth and high levels of rejection, control, and inconsistency were accompanied by high levels of anger/hostility. Finally, regression analyses showed that both attachment status and parental rearing behaviors accounted for a unique and significant proportion of the variance in anger/hostility. These findings are in keeping with the notion that family environment factors such as attachment style and parental rearing are involved in the development of anger/hostility in youths.

Do Hostile School Environments Promote Social Deviance by Shaping Neural Responses to Social Exclusion?

Schriber, Roberta A; Rogers, Christina R; Ferrer, Emilio; Conger, Rand D; Robins, Richard W; Hastings, Paul D; Guyer, Amanda E

2018-03-01

The present study examined adolescents' neural responses to social exclusion as a mediator of past exposure to a hostile school environment (HSE) and later social deviance, and whether family connectedness buffered these associations. Participants (166 Mexican-origin adolescents, 54.4% female) reported on their HSE exposure and family connectedness across Grades 9-11. Six months later, neural responses to social exclusion were measured. Finally, social deviance was self-reported in Grades 9 and 12. The HSE-social deviance link was mediated by greater reactivity to social deviance in subgenual anterior cingulate cortex, a region from the social pain network also implicated in social susceptibility. However, youths with stronger family bonds were protected from this neurobiologically mediated path. These findings suggest a complex interplay of risk and protective factors that impact adolescent behavior through the brain. © 2018 Society for Research on Adolescence.

Defensive measures against hostile takeovers in Slovenia

Directory of Open Access Journals (Sweden)

Andrej Bertoncel

2005-12-01

Full Text Available This article summarizes the corporate takeover regime and defensive measures against hostile takeover bids in Slovenia. Although takeover legislation does not differentiate between hostile and friendly takeover, it prescribes the limitation of powers for the management of the target company, with the intention of preventing the use of defensive measures against the hostile takeover. In light of an expected rise in hostile takeover bids in Slovenia, the Corporate Act and the Takeover Act are analysed and accordingly the array of possible preventive measures as well as ad-hoc measures against hostile bids identified and evaluated for their anti-takeover effectiveness. A hostile takeover in Slovenia usually involves a hostile public tender offer at a substantial premium over the prevailing market price for a substantial percentage of the target company’s stock. Managers of target companies use in takeover battles a variety of defensive tactics, which could be controversial because they pose a conflict of interest for management. Duty of neutrality of the management of the target company during takeover process is therefore discussed in connection with the limitation of use of applicable ad hoc defence mechanisms in that period.

Assunta, M; Chapman, S

2004-12-01

To review how tobacco transnational companies conducted their business in the hostile environment of Singapore, attempting to counter some of the government's tobacco control measures; to compare the Malaysian and the Singaporean governments' stance on tobacco control and the direct bearing of this on the way the tobacco companies conduct their business. Systematic keyword and opportunistic website searches of formerly private internal industry documents. The comprehensive prohibition on advertising did not prevent the companies from advertising cigarettes to Singaporeans. Both British American Tobacco and Philip Morris used Malaysian television to advertise into Singapore. To launch a new brand of cigarettes, Alpine, Philip Morris used a non-tobacco product, the Alpine wine cooler. Other creative strategies such as innovative packaging and display units at retailers were explored to overcome the restrictions. Philip Morris experimented with developing a prototype cigarette using aroma and sweetened tipping paper to target the young and health conscious. The industry sought to weaken the strong pack warnings. The industry distributed anti-smoking posters for youth to retailers but privately salivated over their market potential.

Protection against hostile algorithms in UNIX software

1996-03-01

Protection against hostile algorithms contained in Unix software is a growing concern without easy answers. Traditional methods used against similar attacks in other operating system environments such as MS-DOS or Macintosh are insufficient in the more complex environment provided by Unix. Additionally, Unix provides a special and significant problem in this regard due to its open and heterogeneous nature. These problems are expected to become both more common and pronounced as 32 bit multiprocess network operating systems become popular. Therefore, the problems experienced today are a good indicator of the problems and the solutions that will be experienced in the future, no matter which operating system becomes predominate.

The challenge of executive team building in the aftermath of a hostile takeover

International Nuclear Information System (INIS)

Scott, R. G.

1997-01-01

In a hostile takeover, the executives of the acquired company are likely to have strong feelings that they may be unwanted by and considered disloyal to the the new company. They are likely to be filled with a sense that the 'new company' will 'get even with them' for the resistance put up to the merger. Therefore, the new company must be conscious of and sensitive to the fact that a strained environment exists and one of its first priorities should be to reduce that strain. Experience shows that a well informed Transition Team can minimize the emotional impacts of a hostile takeover and contribute significantly to the eventual success of the merger. To assure success, the Transition Team should be appointed early in the negotiating phase. It should have ready access to the negotiating team and the CEO to keep them fully informed of risk management issues caused by human resource. It should be involved in the strategic planning process during the pre-merger stage. It should have major responsibility for developing human resource impact studies, the development of organizational structure, the integration and implementation planning and monitoring of the progress of implementation. A list of Transition Team responsibilities and a list of proven techniques for turning a hostile environment into a productive win/win team environment are also included

Patient characteristics and attitudes can affect how patients react to the physician's communication style, and this reaction can then influence consultation outcomes. The goal of the present study was to investigate whether the attitude of a sexist male patient affects how he perceives a female physician's nonverbal communication and whether this then results in expecting less positive consultation outcomes. Participants were analog patients who viewed four videotaped male and four videotaped female physicians in a consultation with one of their patients. Physician videos were preselected to represent a range of high and low patient-centered physician nonverbal behavior. Participants filled in questionnaires to assess how patient-centered they perceived the female and male physicians' nonverbal communication to be, and participants indicated how positive they expected the consultation outcomes to be. Moreover, we assessed the participants' sexist attitudes with a questionnaire measuring hostile and benevolent sexism. Students (N = 60) from a French-speaking university in Switzerland were recruited on campus. The main outcome measures were the extent to which analog patients expect the consultation outcomes to be positive (high satisfaction, increased trust in the physician, intention to adhere to treatment recommendations, and perceived physician competence) and the extent to which analog patients perceive physicians as patient-centered (judged from the physicians' nonverbal cues). Male analog patients' hostile sexism was negatively related to perceiving the physicians as patient-centered, and male analog patients' hostile sexism was also negatively related to expected positive consultation outcomes. For male patients viewing female physicians, mediation analysis revealed that perceived physician patient-centeredness mediated the negative relationship between hostile sexism and expected positive consultation outcomes. Male hostile sexist patients perceive a female

Hostility and Anger in Chronic Pain

Full Text Available Introduction: The affective component of pain incorporates various emotions, primarily negative in quality. A great emphasis has been traditionally given to the role of depression and anxiety in chronic pain. More recently, the focus has been directed towards hostility and anger, as fundamental components of the emotional experience of chronic pain. Objective: The aim of this article is to present a literature’s review about the association between chronic pain, anger and hostility. Discussion: Patients with several chronic disorders are characterized by high levels of trait anger and hostility. On the other hand, the manner in which angry feelings are typically handled (anger management style, especially the marked tendency to suppress or express angry feelings, is a particularly important determinant of the chronic pain severity. Conclusion: Hostility and anger are involved in the development, maintenance and treatment of chronic pain. Further research is needed to clarify its relationship with chronic pain and to evaluate the effects of anger management on treatment outcomes.

Socially disruptive behavior during peer interactions in early childhood is detrimental to children’s social, emotional, and academic development. Few studies have investigated the developmental underpinnings of children’s socially disruptive behavior using genetically-sensitive research designs that allow examination of parent-on-child and child-on-parent (evocative genotype-environment correlation) effects when examining family process and child outcome associations. Using an adoption-at-birth design, the present study controlled for passive genotype-environment correlation and directly examined evocative genotype-environment correlation (rGE) while examining the associations between family processes and children’s peer behavior. Specifically, the present study examined the evocative effect of genetic influences underlying toddler low social motivation on mother-child and father-child hostility, and the subsequent influence of parent hostility on disruptive peer behavior during the preschool period. Participants were 316 linked triads of birth mothers, adoptive parents, and adopted children. Path analysis showed that birth mother low behavioral motivation predicted toddler low social motivation, which predicted both adoptive mother-child and father-child hostility, suggesting the presence of an evocative genotype-environment association. In addition, both mother-child and father-child hostility predicted children’s later disruptive peer behavior. Results highlight the importance of considering genetically-influenced child attributes on parental hostility that in turn link to later child social behavior. Implications for intervention programs focusing on early family processes and the precursors of disrupted child social development are discussed. PMID:24364829

Anxious and Hostile: Consequences of Anxious Adult Attachment in Predicting Male-Perpetrated Sexual Assault.

Barbaro, Nicole; Parkhill, Michele R; Nguyen, David

2018-07-01

Attachment theory has increasingly been utilized to understand the etiology of sexual violence, and anxious attachment appears to be especially informative in this domain. We investigate the influence of general anxious attachment and specific anxious attachment on hostile masculine attitudes to predict male-perpetrated sexual assault. We hypothesize that hostile masculinity will mediate the relationship between general anxious attachment style and sexual assault perpetration (Hypothesis 1) and the relationship between specific anxious attachment to the assaulted woman and sexual assault perpetration (Hypothesis 2). Men ( N = 193) completed the Sexual Experiences Survey (SES) to determine sexual assault history and completed measures of general attachment style, specific attachment to the woman involved in the sexual activity, and measures of hostile masculine attitudes. Results support the hypothesized mediation models, such that general anxious attachment and specific anxious attachment are significantly associated with hostile masculinity, which in turn, predicts the likelihood of male-perpetrated sexual assault. The findings suggest that the unique characteristics of anxious attachment may escalate into hostile masculinity, which then increases the likelihood of sexual assault perpetration. This research is the first to investigate attachment bonds to the woman involved in the sexual activity and likelihood of sexual assault perpetration against the same woman.

Neural Correlates of Hostile Jokes: Cognitive and Motivational Processes in Humor Appreciation

Yu-Chen Chan

2016-10-01

Full Text Available Hostile jokes provide aggressive catharsis and a feeling of superiority. Behavioral research has found that hostile jokes are perceived as funnier than non-hostile jokes. The purpose of the present study was to identify the neural correlates of the interaction between type and humor by comparing hostile jokes (HJs, non-hostile jokes (NJs, and their corresponding hostile sentences (HSs and non-hostile sentences (NSs. Hostile jokes primarily showed activation in the dorsomedial prefrontal cortex (dmPFC and midbrain compared with the corresponding hostile baseline. Conversely, non-hostile jokes primarily revealed activation in the ventromedial PFC (vmPFC, amygdala, midbrain, ventral anterior cingulate cortex, and nucleus accumbens (NAcc compared with the corresponding non-hostile baseline. These results support the critical role of the medial prefrontal cortex (mPFC for the neural correlates of social cognition and socio-emotional processing in response to different types of jokes. Moreover, the processing of hostile jokes showed increased activation in the dmPFC, which suggested cognitive operations of social motivation, whereas the processing of non-hostile jokes displayed increased activation in the vmPFC, which suggested social-affective engagement. Hostile jokes versus non-hostile jokes primarily showed increased activation in the dmPFC and midbrain, whereas non-hostile jokes versus hostile jokes primarily displayed greater activation in the amygdala and midbrain. The psychophysiological interaction (PPI analysis demonstrated functional coupling of the dmPFC-dlPFC and midbrain-dmPFC for hostile jokes and functional coupling of the vmPFC-midbrain and amygdala-midbrain-NAcc for non-hostile jokes. Surprisingly, the neural correlates of hostile jokes were not perceived as funnier than non-hostile jokes. Future studies could further investigate the neural correlates of potentially important traits of high-hostility tendencies in humor appreciation

The goal of the current study is to clarify the relationship between social information processing (e.g., visual attention to cues of hostility, hostility attribution bias, and facial expression emotion labeling) and aggressive tendencies. Thirty adults were recruited in the eye-tracking study that measured various components in social information processing. Baseline aggressive tendencies were measured using the Buss-Perry Aggression Questionnaire (AQ). Visual attention towards hostile objects was measured as the proportion of eye gaze fixation duration on cues of hostility. Hostility attribution bias was measured with the rating results for emotions of characters in the images. The results show that the eye gaze duration on hostile characters was significantly inversely correlated with the AQ score and less eye contact with an angry face. The eye gaze duration on hostile object was not significantly associated with hostility attribution bias, although hostility attribution bias was significantly positively associated with the AQ score. Our findings suggest that eye gaze fixation time towards non-hostile cues may predict aggressive tendencies.

A collaborative smartphone sensing platform for detecting and tracking hostile drones

In recent years, not only United States Armed Services but other Law-enforcement agencies have shown increasing interest in employing drones for various surveillance and reconnaissance purposes. Further, recent advancements in autonomous drone control and navigation technology have tremendously increased the geographic extent of dronebased missions beyond the conventional line-of-sight coverage. Without any sophisticated requirement on data links to control them remotely (human-in-loop), drones are proving to be a reliable and effective means of securing personnel and soldiers operating in hostile environments. However, this autonomous breed of drones can potentially prove to be a significant threat when acquired by antisocial groups who wish to target property and life in urban settlements. To further escalate the issue, the standard detection techniques like RADARs, RF data link signature scanners, etc..., prove futile as the drones are smaller in size to evade successful detection by a RADAR based system in urban environment and being autonomous, have the capability of operating without a traceable active data link (RF). Hence, towards investigating possible practical solutions for the issue, the research team at AFRL's Tec^Edge Labs under SATE and YATE programs has developed a highly scalable, geographically distributable and easily deployable smartphone-based collaborative platform that can aid in detecting and tracking unidentified hostile drones. In its current state, this collaborative platform built on the paradigm of "Human-as-Sensors", consists primarily of an intelligent Smartphone application that leverages appropriate sensors on the device to capture a drone's attributes (flight direction, orientation, shape, color, etc..,) with real-time collaboration capabilities through a highly composable sensor cloud and an intelligent processing module (based on a Probabilistic model) that can estimate and predict the possible flight path of a hostile drone

2011-01-01

The Life Style Index (LSI) was designed to assess defense mechanisms, assuming that their use is related to specific emotional states and diagnostic concepts. Aiming to further investigate the psychometric properties of the Greek version of the LSI, the aim of the present study was to investigate the relationship of specific defense mechanisms with dimensions of psychological distress and hostility features in three different populations. The sample comprised 1261 adults (410 healthy participants, 723 medical patients and 128 psychiatric patients). Along with defense mechanisms (LSI), Psychological Distress (General Health Questionnaire, GHQ-28) and Hostility features (Hostility and Direction of Hostility Questionnaire, HDHQ) were also assessed. The results showed that increased psychological distress is related with increased use of all defenses except Denial, with which psychological distress is negatively associated. Regression is constantly related with psychological distress and differentiates psychiatric patients from the other groups of participants, while Compensation and Reaction Formation are related to depressive symptomatology. In medical patients, Repression was found to increase the physical dimension of psychological distress and the social dysfunction. On the contrary,Denial was negatively associated with these dimensions of psychological distress. In the psychiatric patient and healthy participant samples, Projection plays the most detrimental role. Regarding hostility and direction of hostility, those who were found to introvert their hostility presented with higher scores in Denial, indicating that they possibly 'deny' their hostility, and the degree of the Denial was found to be negatively associated with the degree of Introverted Hostility. Those who directed their hostility towards the others, presented with higher rates of Projection, while neither Denial nor Reaction Formation seemed sufficient enough to temper the degree of Extroverted

Hostile people tend to view the world as a hostile place. Although there are individual differences in hostile world-views, situational factors can also play a role. For example, scenes of violence in the mass media might influence people to view the world as a hostile place. This meta-analysis aggregates, for the first time, all studies that have investigated the link between exposure to violent media and hostile appraisals (e.g., perceiving the ambiguous actions by others as aggressive actions). This meta-analysis included 37 independent studies involving 10,410 participants. The results showed a "small" to "moderate" sized average correlation between exposure to violent media and hostile appraisals (r +  = .20, 95%CI = .14, .26). Significant correlations were found in experimental, cross-sectional, and longitudinal studies, indicating a triangulation of evidence. Effects were not correlated with participant gender. Effects were also stable over time. However, the link between exposure to violent media and hostile appraisals was positively related to age, perhaps because violent media can have cumulative effects over time. There was no evidence of publication bias. The findings from this meta-analysis are consistent with the General Aggression Model (e.g., Anderson, & Bushman, 2002; Annual Review of Psychology 53:27-51). These results compliment those from previous meta-analyses showing that violent media can increase aggressive thoughts, angry feelings, physiological arousal, and aggressive behavior. These findings also have practical significance, because people who view the world in a hostile manner are more likely to behave aggressively themselves. Aggr.

Extant research has examined both genetic and environmental risk involved in the transmission of callous-unemotional traits in youth populations, yet no study has examined the intergenerational similarity of these traits between parents and their offspring. The current study examined whether the association between parent callous-unemotional traits and child callous-unemotional traits was mediated by parenting behavior and whether this association was moderated by household environment. Participants included 115 dyads of adolescents (48% female; Mean age = 13.97) and their primary caregivers (87% female; Mean age = 42.54). Measures of callous-unemotional traits, hostile parenting, and household chaos were collected from both adolescents and parents. A two group structural equation modeling revealed that hostile parenting serves as a mediating process in the association between parent and adolescent callous-unemotional traits, but only in the context of high household chaos. Our findings suggest that hostile parenting practices are a mediating process that may explain intergenerational similarity in callous-unemotional traits. Additionally, household chaos may exacerbate the effects of hostile parenting on callous-unemotional traits within adolescents, resulting in heightened vulnerability to intergenerational transmission of callous-unemotional traits.

The authors tested a model, inspired by affective events theory (H. M. Weiss & R. Cropanzano, 1996), that examines the dynamic nature of emotions at work, work attitudes, and workplace deviance. Sixty-four employees completed daily surveys over 3 weeks, reporting their mood, job satisfaction, perceived interpersonal treatment, and deviance. Supervisors and significant others also evaluated employees' workplace deviance and trait hostility, respectively. Over half of the total variance in workplace deviance was within-individual, and this intraindividual variance was predicted by momentary hostility, interpersonal justice, and job satisfaction. Moreover, trait hostility moderated the interpersonal justice-state hostility relation such that perceived injustice was more strongly related to state hostility for individuals high in trait hostility.

Evidence for an association between hostility and peptic ulcer mainly relies on cross-sectional studies. Prospective studies are rare and have not used a validated measure of hostility. This prospective study aimed to examine the association between hostility and peptic ulcer in the large-scale French GAZEL cohort. In 1993, 14,674 participants completed the Buss and Durkee Hostility Inventory. Participants were annually followed-up from 1994 to 2011. Diagnosis of peptic ulcer was self-reported. The association between hostility scores and ulcer incidence was measured by hazard ratios (HR) and 95% confidence intervals computed through Cox regression. Among 13,539 participants free of peptic ulcer history at baseline, 816 reported a peptic ulcer during a mean follow-up of 16.8 years. Adjusting for potential confounders, including smoking, occupational grade, and a proxy for nonsteroidal anti-inflammatory drug exposure, ulcer incidence was positively associated with total hostility (HR per SD: 1.23, confidence interval: 1.14-1.31), behavioral hostility (HR per SD: 1.13, confidence interval: 1.05-1.21), cognitive hostility (HR per SD: 1.26, confidence interval: 1.18-1.35), and irritability (HR per SD: 1.20, confidence interval: 1.12-1.29). The risk of peptic ulcer increased from the lowest to the highest quartile for all hostility measures (p for linear trend peptic ulcer. Should these results be replicated, further studies would be needed to explore the underlying mechanisms.

Social class rank, threat vigilance, and hostile reactivity.

Lower-class individuals, because of their lower rank in society, are theorized to be more vigilant to social threats relative to their high-ranking upper-class counterparts. This class-related vigilance to threat, the authors predicted, would shape the emotional content of social interactions in systematic ways. In Study 1, participants engaged in a teasing interaction with a close friend. Lower-class participants--measured in terms of social class rank in society and within the friendship--more accurately tracked the hostile emotions of their friend. As a result, lower-class individuals experienced more hostile emotion contagion relative to upper-class participants. In Study 2, lower-class participants manipulated to experience lower subjective socioeconomic rank showed more hostile reactivity to ambiguous social scenarios relative to upper-class participants and to lower-class participants experiencing elevated socioeconomic rank. The results suggest that class affects expectations, perception, and experience of hostile emotion, particularly in situations in which lower-class individuals perceive their subordinate rank.

There is growing social concern about school violence but little is known about how this situation is experienced in the schools. The objective of this study was to know the perception that School's head masters have of the school-based hostility, on their causes, how they value current preventive strategies, and their recommendations to develop future preventive interventions. We conducted an exploratory study with 14 semistructured interviews of School's head masters. Interviews were conducted at the Schools between May and June 2003 in 1 independent school, 9 state comprehensive schools, and 4 other comprehensive schools within the city of Alicante. The perception of the head masters is that the prevalence of violence is low, more verbal than physical and within gender. They identify lack of punctuality, absenteeism and lack of interest as forms of hostility. As causes they identified age, family problems, school environment, society, media (TV and video-games) and poor language skills. Preventive methods in use were, on one hand, extra-lessons and transversal contents foreseen in the Education Law and common to all schools, and, on the other hand, ideological and pedagogical contents which were specific of some centres. Recommendations focused in demands for increased economic support and skilled human resources. School-based violence is not perceived as an alarming school issue, nor by its magnitude neither by the immediate causes and students' characteristics to which it is associated. A heavier emphasis is placed on external and environmental causes perceived as much more difficult to confront.

Full Text Available Background. It was hypothesized that television viewing is predictive of cardiometabolic risk. Moreover, people with hostile personality type may be more susceptible to TV-induced negative emotions and harmful health habits which increase occurrence of cardiometabolic risk. Purpose. The prospective association of TV viewing on cardiometabolic risk was examined along with whether hostile personality trait was a modifier. Methods. A total of 3,269 Black and White participants in the coronary artery risk development in young adults (CARDIA study were assessed from age 23 to age 35. A cross-lagged panel model at exam years 5, 10, 15, and 20, covering 15 years, was used to test whether hours of daily TV viewing predicted cardiometabolic risk, controlling confounding variables. Multiple group analysis of additional cross-lagged panel models stratified by high and low levels of hostility was used to evaluate whether the association was modified by the hostile personality trait. Results. The cross-lagged association of TV viewing at years 5 and 15 on clustered cardiometabolic risk score at years 10 and 20 was significant (B=0.058 and 0.051, but not at 10 to 15 years. This association was significant for those with high hostility (B=0.068 for exam years 5 to 10 and 0.057 for exam years 15 to 20 but not low hostility. Conclusion. These findings indicate that TV viewing is positively associated with cardiometabolic risk. Further, they indicate that hostility might be a modifier for the association between TV viewing and cardiometabolic risk.

Both hostile parenting and parental psychopathology have been shown to predict depression in the offspring. However, whether and how they interact in predicting the longitudinal course of depression from adolescence to adulthood remains unclear. Participants were from the prospective Cardiovascular Risk in Young Finns study, aged 3-18 years at baseline in 1980. We used multilevel modeling for repeated measurements to examine the associations of hostile parenting (i.e., parental intolerance and emotional distance) and parental history of psychopathology with trajectories of depressive symptoms across five study phases from 1992 to 2012. On average, depressive symptoms decreased in a curvilinear pattern with age. A relatively steep decreasing trend was also observed among offspring of parents with a history of psychopathology but low intolerance. By contrast, among the offspring of parents with a history of psychopathology and high intolerance there was a rising trend in depressive symptoms starting from young adulthood. There was no similar interaction between parental history of psychopathology, emotional distance, and age. Non-standardized, parental self-report scales were used to measure hostile parenting. The observed effects were small, and the depressive symptoms scale applied in the study may not be used for measuring clinical depression. Parental psychopathology might render individuals sensitive to the unfavorable characteristics of the caregiving environment. Intolerance towards the child can exacerbate the effects of parental psychopathology and have a long-term significance on the developmental trajectory of depressive symptoms over the life-course.

Investigate (1) the association of child adiposity with parent-to-child and parent-to-parent hostility, (2) the mediation of these associations by dietary behaviours and (3) moderation by gender. One hundred thirty-five couples with 6- to 14-year-old children completed measures of emotional and physical aggression, overreactive discipline and child diet. Parent-to-parent hostility was also coded from laboratory observations. Child adiposity was a combination of body mass index and waist-to-hip ratio. Mother-to-child hostility was associated with child adiposity. This association was concentrated in boys and was not significantly explained by child dietary factors. Mother-to-father hostility was not significantly associated with boys' or girls' adiposity. Girls' adiposity was not significantly associated with family hostility. Fathers' hostility was not linked to child adiposity. This is the first study to take a family-level approach to understanding the relation of hostility to child adiposity by examining relations among adiposity and both mothers' and fathers' hostility directed toward one another and toward their children. Our findings highlight the potential role played by mothers' emotional hostility in boys' adiposity and suggest that, if this role is further substantiated, mother-son emotional hostility may be a promising target for the prevention of child obesity.

Hostile attribution biases for relationally provocative situations and event-related potentials.

Godleski, Stephanie A; Ostrov, Jamie M; Houston, Rebecca J; Schlienz, Nicolas J

2010-04-01

This exploratory study investigates how hostile attribution biases for relationally provocative situations may be related to neurocognitive processing using the P300 event-related potential. Participants were 112 (45 women) emerging adults enrolled in a large, public university in upstate New York. Participants completed self-report measures on relational aggression and hostile attribution biases and performed an auditory perseveration task to elicit the P300. It was found that hostile attribution biases for relational provocation situations was associated with a larger P300 amplitude above and beyond the role of hostile attribution biases for instrumental situations, relational aggression, and gender. Larger P300 amplitude is interpreted to reflect greater allocation of cognitive resources or enhanced "attending" to salient stimuli. Implications for methodological approaches to studying aggression and hostile attribution biases and for theory are discussed, as well as implications for the fields of developmental psychology and psychopathology.

The purpose of this study was to examine the effects of gender on the relationship between multidimensional hostility and psychosomatic symptoms in Chinese culture. The participants in this study were 398 Chinese college students (40% female) recruited from Taiwan. Four dimensions of multidimensional hostility-hostility cognition, hostility affect, expressive hostility behavior, and suppressive hostility behavior-were measured by the Chinese Hostility Inventory. After controlling for the effects of depression and anxiety, the results of path analysis revealed that the multidimensional hostility predicted psychosomatic symptoms directly, and predicted psychosomatic symptoms indirectly through negative health behavior. Furthermore, gender moderated the relationships between multidimensional hostility and health outcomes. Expressive hostility exacerbated psychosomatic symptom in females but buffered it in males, while affective hostility exacerbated psychosomatic symptoms in males. Additionally, suppressive hostility behavior was correlated to psychosomatic symptoms indirectly through negative health behavior in females. Moreover, expressive hostility was correlated to psychosomatic symptoms indirectly through negative health behavior more in males than in females.

Adolescent and Parental Contributions to Parent-Adolescent Hostility Across Early Adolescence.

Early adolescence is characterized by increases in parent-adolescent hostility, yet little is known about what predicts these changes. Utilizing a fairly large sample (N = 416, 51 % girls, 91 % European American), this study examined the conjoint and unique influences of adolescent social anxiety symptoms and parental intrusiveness on changes in parent-adolescent hostility across early adolescence. Higher mother and father intrusiveness were associated with increased mother- and father-adolescent hostility. An examination of reciprocal effects revealed that mother- and father-adolescent hostility predicted increased mother and father intrusiveness. Significant associations were not substantiated for adolescent social anxiety symptoms. These findings suggest that intrusive parenting has important implications for subsequent parent-adolescent interactions and that similar patterns may characterize some aspects of mother- and father-adolescent relationships.

Hostility in association with depression seems to be connected to suicidal behavior. This study aimed to evaluate hostility and its dimensions in relation to depression in patients who suffered from diagnosed depression with and without a suicide attempt history. The study included 168 participants; 58 patients with depression and suicide attempt history, 55 patients with depression without a suicide attempt history and 55 healthy controls. Hostility was assessed with the Hostility and Direction of Hostility Questionnaire, while depression with the Beck Depression Inventory (BDI). Patients with depression and a suicide attempt history compared with the patients without attempt history presented statistically significantly higher total hostility (28.71 ± 6.43 vs 24.20 ± 7.66), extroverted hostility (17.16 ± 4.37 vs 14.15 ± 4.63), acting out hostility (6.03 ± 2.09 vs 4.73 ± 1.93), and self criticism (6.95 ± 2.12 vs 5.89 ± 2.32). No statistically significant differences were found between the two clinical groups in depression according to the BDI. Moreover depressive patients with suicide attempt history scored higher in all the hostility dimensions than the controls. Therefore, it could be suggested that hostility and especially its extrapunitive dimensions are associated with suicidal behavior, since no differences in depression were recorded between the two clinical groups.

Previous research has indicated that training in the martial arts leads to a reduction in levels of hostility. However, such research has only compared hostility within martial arts groups. The present research compares two martial arts groups and two other sporting groups on levels of assaultive, verbal and indirect hostility. Moderated multiple regression analyses revealed a significant interaction between length of training in the respondent's stated sport and whether that sport was a martial art in predicting assaultive and verbal hostility. The form of the interaction suggests that participation in the martial arts is associated, over time, with decreased feelings of assaultive and verbal hostility. PMID:1422642

Insights into Sexism: Male Status and Performance Moderates Female-Directed Hostile and Amicable Behaviour.

Directory of Open Access Journals (Sweden)

Michael M Kasumovic

Full Text Available Gender inequality and sexist behaviour is prevalent in almost all workplaces and rampant in online environments. Although there is much research dedicated to understanding sexist behaviour, we have almost no insight into what triggers this behaviour and the individuals that initiate it. Although social constructionist theory argues that sexism is a response towards women entering a male dominated arena, this perspective doesn't explain why only a subset of males behave in this way. We argue that a clearer understanding of sexist behaviour can be gained through an evolutionary perspective that considers evolved differences in intra-sexual competition. We hypothesised that female-initiated disruption of a male hierarchy incites hostile behaviour from poor performing males who stand to lose the most status. To test this hypothesis, we used an online first-person shooter video game that removes signals of dominance but provides information on gender, individual performance, and skill. We show that lower-skilled players were more hostile towards a female-voiced teammate, especially when performing poorly. In contrast, lower-skilled players behaved submissively towards a male-voiced player in the identical scenario. This difference in gender-directed behaviour became more extreme with poorer focal-player performance. We suggest that low-status males increase female-directed hostility to minimize the loss of status as a consequence of hierarchical reconfiguration resulting from the entrance of a woman into the competitive arena. Higher-skilled players, in contrast, were more positive towards a female relative to a male teammate. As higher-skilled players have less to fear from hierarchical reorganization, we argue that these males behave more positively in an attempt to support and garner a female player's attention. Our results provide the clearest picture of inter-sexual competition to date, highlighting the importance of considering an evolutionary

2016-01-01

Hostile jokes (HJs) provide aggressive catharsis and a feeling of superiority. Behavioral research has found that HJs are perceived as funnier than non-hostile jokes (NJs). The purpose of the present study was to identify the neural correlates of the interaction between type and humor by comparing HJs, NJs, and their corresponding hostile sentences (HSs) and non-hostile sentences (NSs). HJs primarily showed activation in the dorsomedial prefrontal cortex (dmPFC) and midbrain compared with the corresponding hostile baseline. Conversely, NJs primarily revealed activation in the ventromedial PFC (vmPFC), amygdala, midbrain, ventral anterior cingulate cortex, and nucleus accumbens (NAcc) compared with the corresponding non-hostile baseline. These results support the critical role of the medial PFC (mPFC) for the neural correlates of social cognition and socio-emotional processing in response to different types of jokes. Moreover, the processing of HJs showed increased activation in the dmPFC, which suggested cognitive operations of social motivation, whereas the processing of NJs displayed increased activation in the vmPFC, which suggested social-affective engagement. HJs versus NJs primarily showed increased activation in the dmPFC and midbrain, whereas NJs versus HJs primarily displayed greater activation in the amygdala and midbrain. The psychophysiological interaction (PPI) analysis demonstrated functional coupling of the dmPFC-dlPFC and midbrain-dmPFC for HJs and functional coupling of the vmPFC-midbrain and amygdala-midbrain-NAcc for NJs. Surprisingly, HJs were not perceived as funnier than NJs. Future studies could further investigate the neural correlates of potentially important traits of high-hostility tendencies in humor appreciation based on the psychoanalytic and superiority theories of humor.

Analyze This! Thematic Analysis: Hostility, Attribution of Intent, and Interpersonal Perception Bias.

Karadenizova, Zhana; Dahle, Klaus-Peter

2017-11-01

Research suggests that aggressive individuals exhibit a strong tendency to attribute hostile intent to the behavior of others when confronted with an ambiguous social situation. The vignettes method has become a standard procedure to assess hostile attributions. Vignettes represent incomplete ambiguous social stories, in which the subjects experience a negative outcome and are asked to attribute intent to the provocateur's action. This article explores the ways in which subjects perceive ambiguous social situations and other people's intentions, their tendency to refer negative outcome to oneself, and the components defining hostility in the interpersonal relationships. The sample consisted of male adolescent violent offenders ( N = 45) recruited from the Social Therapy Department of the German correctional facility for juvenile offenders in Berlin. All offenders were incarcerated for a violent or sexual crime and were currently undergoing individual and group psychotherapy. The five hypothetical vignettes used in this study were originally designed to assess hostile attributions in both institutional and noninstitutional social situations. Participants' responses were analyzed using thematic analysis. Thematic analysis revealed three key themes regarding the social perception-positive, negative, and neutral-and two themes regarding the components of hostility-provocateur-related personality features and relationship type. Although the vignettes were originally developed to detect hostility-prone perception bias, they seem to be able to reveal a wider set of different attributions of intent, both positive and negative. Thus, vignettes are not limited to assessment of hostility specifically. They much rather seem to be a measure which is sensitive to diverse attributions of intent in general. The diagnostic qualities of the vignettes, their area of application, limitations of the study, and future perspective are discussed.

These results support the critical role of the medial PFC (mPFC) for the neural correlates of social cognition and socio-emotional processing in response to different types of jokes. Moreover, the processing of HJs showed increased activation in the dmPFC, which suggested cognitive operations of social motivation, whereas the processing of NJs displayed increased activation in the vmPFC, which suggested social-affective engagement. HJs versus NJs primarily showed increased activation in the dmPFC and midbrain, whereas NJs versus HJs primarily displayed greater activation in the amygdala and midbrain. The psychophysiological interaction (PPI) analysis demonstrated functional coupling of the dmPFC–dlPFC and midbrain–dmPFC for HJs and functional coupling of the vmPFC–midbrain and amygdala–midbrain–NAcc for NJs. Surprisingly, HJs were not perceived as funnier than NJs. Future studies could further investigate the neural correlates of potentially important traits of high-hostility tendencies in humor appreciation based on the psychoanalytic and superiority theories of humor.

This study sought to determine the role of hostility in moderating the effects of positive social interactions on ambulatory blood pressure (ABP). Participants (341 adults) completed the Cook-Medley Hostility Scale and underwent ABP monitoring, assessed every 45 min during waking hours across 6 days. An electronic diary measuring mood and social interactions was completed at each ABP assessment. The dependent variables from the ABP monitor included systolic blood pressure, diastolic blood pressure, and heart rate. Different patterns of ambulatory diastolic blood pressure (ADBP) responding to social interactions perceived as intimate or supportive among high- versus low-hostile individuals were observed. Higher intimacy ratings were linked to reductions in ADBP among low-hostile but not high-hostile individuals. Conversely, high-hostile, but not low-hostile, individuals showed increases in ADBP to situations rated high in social support. Although findings for ambulatory systolic blood pressure were nonsignificant, the pattern of results was similar to ADBP. Hostile individuals may find offers of support stressful and may fail to benefit from intimacy during daily life. The pathogenic effects of hostility may be mediated in part by responses to social interactions, both positive and negative. (c) 2008 APA, all rights reserved

Three hundred seventy-one male substance-abusing volunteers for drug studies were administered the Buss-Durkee Hostility Inventory (B-D). One hundred nineteen of these subjects were readministered the B-D with the instruction to answer the items in terms of their behavior while drinking alcohol, with 67 of these subjects also completing a heroin use condition. Expectancies for hostility under alcohol or heroin were generally uncorrelated with other measures of personality, psychopathology, antisocial personality, impulsiveness, or criminality; but expectancies for hostility under alcohol were predictive of diagnoses of alcohol, opioid, and marijuana abuse and dependence over and above the influence of these other measures.

Hostility, driving anger, and dangerous driving: the emerging role of hemispheric preference.

Science.gov (United States)

Gidron, Yori; Gaygısız, Esma; Lajunen, Timo

2014-12-01

Various studies have implicated psychosocial variables (e.g., hostility) in risk of dangerous driving and traffic accidents. However, whether these variables are related to more basic neurobiological factors, and whether such associations have implications for the modification of psychosocial risk factors in the context of driving, have not been examined in depth. This study examined the relationship between hemispheric preference (HP), hostility and self-reported dangerous driving, and the ability to affect driving anger via hemisphere activating cognitive exercises (HACE). In Study 1, 254 Turkish students completed questionnaires of hostility, HP and driving behavior. In Study 2, we conducted a "proof of concept" experimental study, and tested effects of left, right and neutral HACE on driving anger, by exposing N=650 Turkish students to written scenarios including either logical (left hemisphere), visuo-spatial (right hemisphere) or "mild doses" of both types of contents (control). In Study 1, left-HP was associated with higher hostility and with more dangerous driving, and hostility mediated the relationship between L-HP and reported driving behavior. In Study 2, only right-HACE led to immediate significant reductions in self-reported driving anger. Left-HP is related to hostility and to dangerous driving, and it may be possible to partly reduce driving anger by right-HACE. Future studies must replicate these findings with objective measures, more enduring interventions and longer follow-ups. Copyright © 2014. Published by Elsevier Ltd.

Sanz, Jesús; García-Vera, María Paz; Magán, Inés

2010-06-01

This study was aimed at examining the relationships of the personality dimensions of the five-factor model or Big Five with trait anger and with two specific traits of hostility (mistrust and confrontational attitude), and identifying the similarities and differences between trait anger and hostility in the framework of the Big Five. In a sample of 353 male and female adults, the Big Five explained a significant percentage of individual differences in trait anger and hostility after controlling the effects due to the relationship between both constructs and content overlapping across scales. In addition, trait anger was primarily associated with neuroticism, whereas mistrust and confrontational attitude were principally related to low agreeableness. These findings are discussed in the context of the anger-hostility-aggression syndrome and the capability of the Big Five for organizing and clarifying related personality constructs.

Flash fire and slow burn: women's cardiovascular reactivity and recovery following hostile and benevolent sexism.

Salomon, Kristen; Burgess, Kaleena D; Bosson, Jennifer K

2015-04-01

Women's cardiovascular responses to sexist treatment are documented, but researchers have yet to consider these responses separately as a function of sexism type (hostile vs. benevolent). This study demonstrates distinct effects of hostile and benevolent sexism for women's cardiovascular responses that indicate increased risk for cardiovascular disease. Female participants performed a demanding insight task after exposure to a male researcher who offered them a hostilely sexist, benevolently sexist, or nonsexist comment. Women displayed heightened cardiovascular reactivity (increases from baseline) during the task following hostile sexism, and they displayed impaired cardiovascular recovery (return to baseline after the task) following benevolent sexism. The effects seen in the hostile condition were mediated by self-reported anger. These findings indicate that women's affective responses to hostile and benevolent sexism differ but that exposure to both forms of sexism may have negative cardiovascular consequences.

Me against we: in-group transgression, collective shame, and in-group-directed hostility.

Piff, Paul K; Martinez, Andres G; Keltner, Dacher

2012-01-01

People can experience great distress when a group to which they belong (in-group) is perceived to have committed an immoral act. We hypothesised that people would direct hostility toward a transgressing in-group whose actions threaten their self-image and evoke collective shame. Consistent with this theorising, three studies found that reminders of in-group transgression provoked several expressions of in-group-directed hostility, including in-group-directed hostile emotion (Studies 1 and 2), in-group-directed derogation (Study 2), and in-group-directed punishment (Study 3). Across studies, collective shame-but not the related group-based emotion collective guilt-mediated the relationship between in-group transgression and in-group-directed hostility. Implications for group-based emotion, social identity, and group behaviour are discussed.

Traits of optimism and cynical hostility are features of personality that could influence the risk of falls and fractures by influencing risk-taking behaviors, health behaviors, or inflammation. To test the hypothesis that personality influences falls and fracture risk, we studied 87,342 women enrolled in WHI-OS. Optimism was assessed by the Life Orientation Test-Revised and cynical hostility, the cynicism subscale of the Cook-Medley questionnaire. Higher scores indicate greater optimism and hostility. Optimism and hostility were correlated at r = -0. 31, p optimism and hostility with tests for trends; Q1 formed the referent group. The average follow-up for fractures was 11.4 years and for falls was 7.6 years. In multivariable (MV)-adjusted models, women with the highest optimism scores (Q4) were 11% less likely to report ≥2 falls in the past year (odds ratio [OR] = 0.89; 95% confidence intervals [CI] 0.85-0.90). Women in Q4 for hostility had a 12% higher risk of ≥2 falls (OR = 1.12; 95% CI 1.07-1.17). Higher optimism scores were also associated with a 10% lower risk of fractures, but this association was attenuated in MV models. Women with the greatest hostility (Q4) had a modest increased risk of any fracture (MV-adjusted hazard ratio = 1. 05; 95% CI 1.01-1.09), but there was no association with specific fracture sites. In conclusion, optimism was independently associated with a decreased risk of ≥2 falls, and hostility with an increased risk of ≥2 falls, independent of traditional risk factors. The magnitude of the association was similar to aging 5 years. Whether interventions aimed at attitudes could reduce fall risks remains to be determined. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and Mineral Research.

This paper examines the steps to be taken by a corporation and its board in order to be properly prepared before a hostile takeover bid is made. The procedures and steps to be followed in responding to a bid with a view to maximizing value for shareholders are also outlined. Reasons why a company may become target for a hostile takeover bid are reviewed, followed by a more detailed examination of the responsibilities of a board in responding to a takeover bid. These responsibilities include the adoption of a shareholders' rights plan ('poison pill'), review of executive employment contracts, making sure that a corporate indemnification agreement and directors' and officers' liability insurance plan are in place, implementation of structural deterrents, investor communication plans, preparing the 'black book', creating or updating the list of 'white knights', designating a data room, entering into confidentiality agreements with white knights, preparation of a response timetable, review of recent takeover bids, strategies for dealing with hostile bidders, strategies for enticing one or more a white knights to enter the bidding. Sample copy of a confidentiality agreement is contained in Schedule A. A list of break-up fees in recent Canadian mergers and acquisitions transactions is provided in Schedule B. 24 refs

  Previous studies have linked marital conflict, parenting, and externalizing problems in early childhood. However, these studies have not examined whether genes account for these links nor have they examined whether contextual factors such as parental personality or financial distress might account for links between marital conflict and parenting. We used an adoption design to allow for a clear examination of environmental impact rather than shared genes of parents and children, and assessments of parental personality and financial strain to assess the effects of context on relationships between marriage and parenting of both mothers and fathers.   Participants were 308 adoption-linked families comprised of an adopted child, her/his biological mother (BM), adoptive mother (AM) and adoptive father (AF). BMs were assessed 3-6 and 18 months postpartum and adoptive families were assessed when the child was 18 and 27 months old. Structural equations models were used to examine associations between marital hostility, fathers' and mothers' parenting hostility, and child aggressive behavior at 27 months of age. In addition, the contribution of financial strain and adoptive parent personality traits was examined to determine the associations with the spillover of marital hostility to hostile parenting.   A hostile marital relationship was significantly associated with hostile parenting in fathers and mothers, which were associated with aggressive behavior in toddlers. Subjective financial strain was uniquely associated with marital hostility and child aggression. Antisocial personality traits were related to a more hostile/conflicted marital relationship and to hostile parenting.   Results clarify mechanisms that may account for the success of early parent-child prevention programs that include a focus on parental economic strain and personality in addition to parent training. © 2011 The Authors.

Full Text Available Background: The aim of the study was to assess the relationship between the exposure to workplace bullying and hostile behavior and occupational burnout in a sample of Polish teachers. Material and Methods: In our research we studied a nationwide random sample of 1214 teachers. The frequency and type of hostile behaviors against employees was measured with the use of MDM Questionnaire, (“Mobbing, dręczenie, molestowanie” – “Bullying, harrasement, maltreatment” by Mościcka, Drabek, Merecz, developed in the Department of Occupational Psychology of the Nofer Institute of Occupational Medicine in Łódź (Poland, and the level of burnout was assessed with Maslach Burnout Inventory – General Survey (MBI-GS. Results: As many as 63% of teachers experienced hostile behavior in their workplace and 7% of them experienced workplace bullying. Employees affected by bullying and hostile behavior reported more symptoms of professional burnout, such as emotional exhaustion, cynicism, and lower level of professional efficacy. Conclusions: The majority of teachers in this study experienced some form of hostile behavior in the workplace. One in ten respondents was the subject of workplace bullying. The experience of hostile behavior and bullying at work was significantly connected with symptoms of professional burnout. Therefore, it is desirable to take care of good interpersonal relationships in educational institutions, strengthen teachers’ abilities to cope with difficult interpersonal situations, and implement procedures to prevent bullying and hostile behavior in the workplace.

In the present research, we examine the ways in which exposure to hostile sexism influences women's competitive collective action intentions. Prior to testing our main model, our first study experimentally induced high versus low levels of security-comfort with the aim of providing experimental evidence for the proposed causal link between these emotions and intentions to engage in social competition. Results showed that lower levels of security-comfort reduced women's readiness to compete socially with men. Experiment 2 investigated the effect of hostile sexism on women's emotional reactions and readiness to engage in social competition. Consistent with the proposed model, results showed that exposure to hostile beliefs about women (1) increased anger-frustration and (2) decreased security-comfort. More specifically, exposure to hostile sexism had a positive indirect effect on social competition intentions through anger-frustration, and a negative indirect effect through security-comfort. © 2015 The British Psychological Society.

A Mutual Hostility Explanation for the Co-Occurrence of Delinquency and Depressive Mood in Adolescence.

Different interpersonal experiences are related to delinquency and depressive mood. In many studies, delinquency has been associated with exposing others to hostility, while depressive mood has been associated with being a victim of others' hostility. In this study, we proposed that adolescents with a co-occurrence of high delinquency and depressive mood may be both perpetrators and victims in their relations with parents at home, peers and teachers at school, and other people encountered in leisure time. We studied a normative sample of 1452 mid-adolescents (50.61% boys and 49.38% girls). Cluster analyses found a group with a co-occurrence of high delinquency and high depressive mood. Adolescents in this cluster group were highest on being exposed to hostility, exposing others to hostility, and being involved in mutually hostile interactions with others in different everyday contexts. The findings were especially strong when we examined being a victim and a perpetrator across contexts. The results were similar for boys and girls. We conclude that the co-occurrence of high delinquency and depressive mood among some adolescents is intimately linked to the mutually hostile interactions that these adolescents experience in their everyday interpersonal contexts.

Hostile Attribution Bias as a Mediator of the Relationships of Psychopathy and Narcissism With Aggression.

Science.gov (United States)

Law, Helen; Falkenbach, Diana M

2017-11-01

Hostile attribution bias (HAB), the tendency to perceive hostility in ambiguous situations, has been linked to aggressive outcomes, such as reactive aggression. HAB has been connected to personality types involving hostile beliefs and reactive aggression, including narcissism and psychopathy. Specifically, secondary psychopathy is associated with HAB and reactive aggression. Despite research and theory connecting these constructs, few studies have examined if HAB mediates the relationships among psychopathy, narcissism, and aggression. The current study explores this possible mediation in an urban college sample. Narcissism was associated with aggression but not hostile aggression or HAB. Reactive aggression and HAB were both associated with psychopathy, but there were no mediation relationships. The associations with aggression may be, therefore, due to underlying traits of secondary psychopathy rather than the hostile attributions to which the traits contribute; consequently, treatments focused on reducing aggressive responses by correcting interpretations of social situations may not be successful.

There is an international nursing shortage. Improving the practice environment has been shown to be a successful strategy against this phenomenon, as the practice environment is associated with retention and job satisfaction. The Israeli nurse practice environment has not been measured. The purpose of this study was to measure practice environment characteristics, retention and job satisfaction and to evaluate the association between these variables. A demographic questionnaire, the Practice Environment Scale, and a Job Satisfaction Questionnaire were administered to Israeli acute and intensive care nurses working in 7 hospitals across the country. Retention was measured by intent to leave the organization and work experience. A convenience sample of registered nurses was obtained using a bi-phasic, stratified, cluster design. Data were collected based on the preferences of each unit, either distribution during various shifts or at staff meetings; or via staff mailboxes. Descriptive statistics were used to describe the sample and results of the questionnaires. Pearson Product Moment Correlations were used to determine significant associations among the variables. A multiple regression model was designed where the criterion variable was the practice environment. Analyses of variance determined differences between groups on nurse practice environment characteristics. 610 nurses reported moderate levels of practice environment characteristics, where the lowest scoring characteristic was 'appropriate staffing and resources'. Approximately 9% of the sample reported their intention to leave and the level of job satisfaction was high. A statistically significant, negative, weak correlation was found between intention to leave and practice environment characteristics, with a moderate correlation between job satisfaction and practice environment characteristics. 'Appropriate staffing and resources' was the only characteristic found to be statistically different based on

The present study examined the associations between authoritarian parenting beliefs, attributions of hostile intent, negative affect, and harsh parenting practices. General population parents (N=183; 31.1% fathers) completed self-report measures of authoritarian parenting beliefs and read vignettes describing children engaging in transgressions. Following each vignette, parents indicated the extent to which they would attribute hostile intent to the child, feel negative affect, and respond with harsh parenting practices (e.g., yelling, hitting). As hypothesized, parents who subscribed to higher levels of authoritarian beliefs attributed more hostile intent to the child and expected to feel more negative affect in response to the transgressions. In turn, higher levels of hostile attributions and negative affect were associated with increased likelihood of harsh parenting practices. Results from a path analysis revealed that the association between authoritarian parenting beliefs and harsh parenting practices was fully explained by attributions of hostile intent and negative affect.

Televised relational and physical aggression and children's hostile intent attributions.

Science.gov (United States)

Martins, Nicole

2013-12-01

An experiment was conducted with 150 children (mean age=10.1years) in third to fifth grades to test whether exposure to different forms of aggression in the media affected hostile attributional biases in response to different forms of provocation scenarios. Children were randomly assigned to watch a clip containing physical aggression, relational aggression, or no aggression. After exposure, children were asked to respond to a series of written provocation scenarios where a character caused some form of harm (instrumental or relational) to a target person, but the intent of the provocateur was ambiguous. Results revealed that exposure to relationally aggressive portrayals resulted in a hostile attributional bias in response to relational scenarios, whereas exposure to portrayals of physical aggression was associated with a hostile attributional bias in response to instrumental scenarios. Moreover, these biases were shown to be specific to the exposure condition (physical or relational) and not simply associated with exposure to aggression in general. The findings are discussed in terms of the general aggression model and children's social information processing. Copyright © 2013 Elsevier Inc. All rights reserved.

Developmental precursors of young school-age children's hostile attribution bias.

This prospective longitudinal study provides evidence of preschool-age precursors of hostile attribution bias in young school-age children, a topic that has received little empirical attention. We examined multiple risk domains, including laboratory and observational assessments of children's social-cognition, general cognitive functioning, effortful control, and peer aggression. Preschoolers (N = 231) with a more advanced theory-of-mind, better emotion understanding, and higher IQ made fewer hostile attributions of intent in the early school years. Further exploration of these significant predictors revealed that only certain components of these capacities (i.e., nonstereotypical emotion understanding, false-belief explanation, and verbal IQ) were robust predictors of a hostile attribution bias in young school-age children and were especially strong predictors among children with more advanced effortful control. These relations were prospective in nature-the effects of preschool variables persisted after accounting for similar variables at school age. We conclude by discussing the implications of our findings for future research and prevention. PsycINFO Database Record (c) 2013 APA, all rights reserved.

There is abundant evidence linking hostile proximal aortic neck anatomy to poor outcome after endovascular aortic aneurysm repair (EVAR), yet the definition of hostile anatomy varies from study to study. This current analysis was undertaken to identify anatomic criteria that are most predictive of success or failure at the aortic neck after EVAR. The study group comprised 221 patients in the Aneurysm Treatment using the Heli-FX Aortic Securement System Global Registry (ANCHOR) clinical trial, a population enriched with patients with challenging aortic neck anatomy and failure of sealing. Imaging protocols were not protocol specified but were performed according to the institution's standard of care. Core laboratory analysis assessed the three-dimensional centerline-reformatted computed tomography scans. Failure at the aortic neck was defined by type Ia endoleak occurring at the time of the initial endograft implantation or during follow-up. Receiver operating characteristic curve analysis was used to assess the value of each anatomic measure in the classification of aortic neck success and failure and to identify optimal thresholds of discrimination. Binary logistic regression was performed after excluding highly intercorrelated variables, creating a final model with significant predictors of outcome after EVAR. Among the 221 patients, 121 (54.8%) remained free of type Ia endoleak and 100 (45.2%) did not. Type Ia endoleaks presented immediately after endograft deployment in 58 (58.0%) or during follow-up in 42 (42.0%). Receiver operating characteristic curve analysis identified 12 variables where the classification of patients with type Ia endoleak was significantly more accurate than chance alone. Increased aortic neck diameter at the lowest renal artery (P = .013) and at 5 mm (P = .008), 10 mm (P = .008), and 15 mm (P = .010) distally; aneurysm sac diameter (P = .001), common iliac artery diameters (right, P = .012; left, P = .032), and a conical (P = .049) neck

High-speed uncooled MWIR hostile fire indication sensor

Hostile fire indication (HFI) systems require high-resolution sensor operation at extremely high speeds to capture hostile fire events, including rocket-propelled grenades, anti-aircraft artillery, heavy machine guns, anti-tank guided missiles and small arms. HFI must also be conducted in a waveband with large available signal and low background clutter, in particular the mid-wavelength infrared (MWIR). The shortcoming of current HFI sensors in the MWIR is the bandwidth of the sensor is not sufficient to achieve the required frame rate at the high sensor resolution. Furthermore, current HFI sensors require cryogenic cooling that contributes to size, weight, and power (SWAP) in aircraft-mounted applications where these factors are at a premium. Based on its uncooled photomechanical infrared imaging technology, Agiltron has developed a low-SWAP, high-speed MWIR HFI sensor that breaks the bandwidth bottleneck typical of current infrared sensors. This accomplishment is made possible by using a commercial-off-the-shelf, high-performance visible imager as the readout integrated circuit and physically separating this visible imager from the MWIR-optimized photomechanical sensor chip. With this approach, we have achieved high-resolution operation of our MWIR HFI sensor at 1000 fps, which is unprecedented for an uncooled infrared sensor. We have field tested our MWIR HFI sensor for detecting all hostile fire events mentioned above at several test ranges under a wide range of environmental conditions. The field testing results will be presented.

Detection of Hidden Hostile/Terrorist Groups in Harsh Territories by Using Animals as Mobile Biological Sensors.

Terrorism is the greatest threat to national security and cannot be defeated by conventional military force alone. In critical areas such as Iraq, Afghanistan and Turkey, regular forces cannot reach these hostile/terrorist groups, the instigators of terrorism. These groups have a clear understanding of the relative ineffectiveness of counter-guerrilla operations and rely on guerrilla warfare to avoid major combat as their primary means of continuing the conflict with the governmental structures. In Internal Security Operations, detection of terrorist and hostile groups in their hiding places such as caves, lairs, etc. can only be achieved by professionally trained people such as Special Forces or intelligence units with the necessary experience and tools suitable for collecting accurate information in these often harsh, rugged and mountainous countries. To assist these forces, commercial micro-sensors with wireless interfaces could be utilized to study and monitor a variety of phenomena and environments from a certain distance for military purposes. In order to locate hidden terrorist groups and enable more effective use of conventional military resources, this paper proposes an active remote sensing model implanted into animals capable of living in these environments. By using these mobile sensor devices, improving communications for data transfer from the source, and developing better ways to monitor and detect threats, terrorist ability to carry out attacks can be severely disrupted.

In Internal Security Operations, detection of terrorist and hostile groups in their hiding places such as caves, lairs, etc. can only be achieved by professionally trained people such as Special Forces or intelligence units with the necessary experience and tools suitable for collecting accurate information in these often harsh, rugged and mountainous countries. To assist these forces, commercial micro-sensors with wireless interfaces could be utilized to study and monitor a variety of phenomena and environments from a certain distance for military purposes. In order to locate hidden terrorist groups and enable more effective use of conventional military resources, this paper proposes an active remote sensing model implanted into animals capable of living in these environments. By using these mobile sensor devices, improving communications for data transfer from the source, and developing better ways to monitor and detect threats, terrorist ability to carry out attacks can be severely disrupted.

Collective narcissism moderates the effect of in-group image threat on intergroup hostility.

Results of 4 experiments demonstrated that under in-group image threat collective narcissism predicts retaliatory intergroup hostility. Under in-group criticism (vs. praise) collective narcissists expressed intention to harm the offending out-group but not other, nonoffending out-groups. This effect was specific to collective narcissism and was replicated in studies that accounted for the overlap between collective narcissism and individual narcissism, in-group positivity (in-group identification, blind and constructive patriotism), social dominance orientation, and right wing authoritarianism. The link between collective narcissism and retaliatory intergroup hostility under in-group image threat was found in the context of national identity and international relations and in the context of a social identity defined by university affiliation. Study 4 demonstrated that the relationship between collective narcissism and intergroup hostility was mediated by the perception of in-group criticism as personally threatening. The results advance our understanding of the mechanism driving the link between collective narcissism and intergroup hostility. They indicate that threatened egotism theory can be extended into the intergroup domain. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Ambivalent Sexism in Close Relationships: (Hostile) Power and (Benevolent) Romance Shape Relationship Ideals

2013-01-01

Gender-based structural power and heterosexual dependency produce ambivalent gender ideologies, with hostility and benevolence separately shaping close-relationship ideals. The relative importance of romanticized benevolent versus more overtly power-based hostile sexism, however, may be culturally dependent. Testing this, northeast US (N=311) and central Chinese (N=290) undergraduates rated prescriptions and proscriptions (ideals) for partners and completed Ambivalent Sexism and Ambivalence toward Men Inventories (ideologies). Multiple regressions analyses conducted on group-specific relationship ideals revealed that benevolent ideologies predicted partner ideals, in both countries, especially for US culture’s romance-oriented relationships. Hostile attitudes predicted men’s ideals, both American and Chinese, suggesting both societies’ dominant-partner advantage. PMID:23914004

Hostility and social support explain physical activity beyond negative affect among young men, but not women, in college.

We examined social support as a moderator of cynical hostility in relation to physical activity and body mass index among college students (n = 859; M = 18.71 years (SD = 1.22); 60% women, 84% White). After controlling for negative affect in hierarchical linear regression models, greater hostility was associated with lesser physical activity among those with low social support, as expected. Greater hostility was also associated with greater physical activity among those high in social support, ps men only. Hostility and social support were unrelated to body mass index, ps > .05. Young men with a hostile disposition and low social support may be at risk for a sedentary lifestyle for reasons other than negative affect.

Theory of Mind (ToM) is a social perceptual skill that refers to the ability to take someone else's perspective and infer what others think. The current study examined the effect of potential hostility biases, as well as controlled (slow) versus automatic (fast) processing on ToM performance in psychopathy. ToM abilities (as assessed with the Reading the Mind in the Eyes Test; RMET; Baron-Cohen, Wheelwright, Hill, Raste, & Plumb, 2001), was compared between 39 PCL-R diagnosed psychopathic offenders, 37 non-psychopathic offenders, and 26 nonoffender controls. Contrary to our hypothesis, psychopathic individuals presented with intact overall RMET performance when restrictions were imposed on how long task stimuli could be processed. In addition, psychopaths did not over-ascribe hostility to task stimuli (i.e., lack of hostility bias). However, there was a significant three-way interaction between hostility, processing speed, and psychopathy: when there was no time limit on stimulus presentation, psychopathic offenders made fewer errors in identifying more hostile eye stimuli compared to nonoffender controls, who seemed to be less accurate in detecting hostility. Psychopaths' more realistic appraisal of others' malevolent mental states is discussed in the light of theories that stress its potential adaptive function. Copyright © 2015 Elsevier Ltd.

Individuals with chronic pain may experience negative responses from spouse, family, and friends. Responses such as overt criticism and hostility may be associated with worsening pain and function for chronic pain sufferers. We used a laboratory procedure to evaluate whether variability in spouse criticism/hostility exhibited toward chronic low back pain (CLBP) patients during a conflictual discussion predicted variability in patient pain and function during a subsequent pain-induction task. Chronic low back pain patients (n = 71) and their spouses (n = 71) participated in a 10-minute discussion followed by the patient undergoing a 10-minute structured pain behavior task (SPBT). Spouse criticism/hostility perceived by patients and patient Beck Depression Inventory-II (BDI) scores correlated significantly and positively with pain intensity during the SPBT, whereas perceived spouse hostility, patient BDI scores, and spouse trait hostility correlated significantly and positively with observed pain behaviors during the SPBT. Spouse criticism/hostility coded by raters from video recordings interacted significantly with patient BDI scores, such that observed spouse criticism/hostility was related significantly and positively with pain behaviors only for patients with high BDI scores. Patient sex interacted significantly with observed spouse criticism/hostility, such that observed spouse criticism/hostility was related significantly and positively with pain behaviors only for female patients. Results support the hypothesis that spouse criticism and hostility-actually expressed or perceived-may worsen CLBP patient symptoms. Further, women patients and patients high in depressive symptoms appeared most vulnerable to spouse criticism/hostility. Thus, negative marital communication patterns may be appropriate targets for intervention, especially among these 2 at risk groups.

Background: Patients diagnosed with schizophrenia may be hostile or exhibit aggressive behavior, which can occasion their admission to psychiatric hospital. Antipsychotic medications are often used to treat hostility and aggression in such patients. Paliperidone ER is effective and well tolerated in the treatment of schizophrenia. However, there are no data available for paliperidone ER with regard to its efficacy on hostility and aggression among Thai patients. This study was a part of the PERFEcT study, a 6-month, open-label, multicenter, multicountry, prospective trial to explore the safety, efficacy, and functionality of paliperidone ER tablets. The current study included only the data obtained from Thai participants. Materials and methods: Flexible dosing of paliperidone ER in a range of 3–12 mg/day was used, allowing investigators to adjust the dosage of each subject individually. The 199 Thai patients had a stable Clinical Global Impression – severity score before enrollment. Demographic

The usual posting schedule will resume in January.The Threatening Magnetic and Plasma Environment of the TRAPPIST-1 PlanetsPublished July2017Main takeaway:Modelsof the magnetic environment surrounding the seven planets of the TRAPPIST-1 system suggest that this isnot a pleasant place to be for life. In particular, the simulations run byCecilia Garraffo (Harvard-Smithsonian Center for Astrophysics) and collaborators indicate that all planets in the system are bombarded by a stellar wind with a pressure thats 1,000 to 100,000 times the pressureof what we experience on Earth.Why its interesting:Simulations of the magnetic environment around the planet TRAPPIST-1 f, for a variety of different assumed planetary magnetic fields. Red field lines are those that have connected between the star and the planet. [Garraffo et al. 2017]The discovery of seven Earth-sized planets in the nearby TRAPPIST-1 system particularly given many of the planets apparent location in the stars habitable zone gave us hope that these planets might be an interesting place to look for life. But the issue of habitability is more complicated than whether or not the planets can support liquid water. Garraffo and collaborators models suggest that these planets likely have their atmospheres eroded or completely stripped by the stellar wind, renderingprospects for life on these planets low.Why the TRAPPIST-1 systemis still awesome:We may be bummed that the magnetically active host star impedes chances for life on the TRAPPIST-1 planets, but theenvironment it produces isstill pretty awesome. According to the authors models, the planets pass through wildly changing wind pressure changes as they orbit. In the process, their magnetospheres are compressed, and their magnetic field lines connect with the stellar

Extending color psychology to the personality realm: interpersonal hostility varies by red preferences and perceptual biases.

Fetterman, Adam K; Liu, Tianwei; Robinson, Michael D

2015-02-01

The color psychology literature has made a convincing case that color is not just about aesthetics, but also about meaning. This work has involved situational manipulations of color, rendering it uncertain as to whether color-meaning associations can be used to characterize how people differ from each other. The present research focuses on the idea that the color red is linked to, or associated with, individual differences in interpersonal hostility. Across four studies (N = 376 undergraduates), red preferences and perceptual biases were measured along with individual differences in interpersonal hostility. It was found that (a) a preference for the color red was higher as interpersonal hostility increased, (b) hostile people were biased to see the color red more frequently than nonhostile people, and (c) there was a relationship between a preference for the color red and hostile social decision making. These studies represent an important extension of the color psychology literature, highlighting the need to attend to person-based, as well as situation-based, factors. © 2014 Wiley Periodicals, Inc.

Alcohol Use, Hostile Sexism, and Religious Self-Regulation: Investigating Risk and Protective Factors of IPV Perpetration.

Science.gov (United States)

Lynch, Kellie R; Renzetti, Claire M

2017-05-01

Research suggests that the relationship between alcohol use and intimate partner violence (IPV) is moderated by a range of other factors. Therefore, we investigated the relationship between alcohol use, hostile sexism, and religious self-regulation with perpetration. Using a national sample of 255 men, we found that hostile sexism was associated with physical violence toward a partner and alcohol use was positively associated with psychological abuse toward a partner. With regard to religious self-regulation, we found that introjected religious self-regulation was positively associated with hostile sexism and positively associated with perpetrating physical IPV. Identified religious self-regulation was negatively associated with physical violence perpetration. We also found significant interactions among our independent measures on physical IPV perpetration. These analyses suggest that increased alcohol consumption elevates the risk for physical violence perpetration among men who are high in introjected religious self-regulation and low in hostile sexism, while reducing the risk for perpetration in men who are high in identified religious self-regulation and low in hostile sexism. Implications and limitations of the findings are discussed.

The 5-HTTLPR polymorphism has been associated both with depression and aggression/hostility. The multidirectional association between depression, aggression and the s allele may be important, since all these phenomena are related to suicidal behavior. Our aim was to investigate the association between 5-HTTLPR and aggressive/hostile traits in depressed patients and controls. 137 depressive and 118 control women completed the Buss-Durkee Hostility Inventory and were genotyped for 5-HTTLPR. BDHI scores in the different groups were investigated by Generalized Linear Model Analysis. Association between dependent and independent variables in the model was tested by the likelihood ratio Chi-square statistic. Diagnosis and genotype showed a significant association with several aggressive/hostile traits. Interaction of the two main effects was also significant in case of several subscales. Post hoc analyses indicated a significant association between BDHI subscales and s allele only in the depressed group. Only women were studied and since gender differences are present both in aggressive behavior and putatively in the behavioral effects of 5-HTTLPR genotype, our findings pertain only to females. Our results indicate a robust relationship between aggression/hostility and 5-HTTLPR genotype, but this association is more marked in the presence of depression. The presence of the s allele thus not only contributes to a higher risk of depression, but in depressives also leads to higher aggression/hostility. Our results have important implications for suicide research, since the s allele is associated with violent suicide, and this association may be mediated through the emergence of increased aggression/hostility in depressed patients carrying the s allele.

Impulsivity is a multidimensional construct and has been previously associated with suicidal behaviour in borderline personality disorder (BPD). This study examined the associations between suicidal behaviour and impulsivity-related personality traits, as well as history of childhood sexual abuse, in 76 patients diagnosed with BPD using both the Structured Interview for Diagnostic and Statistical Manual of Mental Disorders III (DSM-III) Axis-II diagnoses and the self-personality questionnaire. Impulsivity-related traits were measured using the Barratt Impulsiveness Scale-11 (BIS-11), the Buss-Durkee Hostility Inventory (BDHI) and the Temperament and Character Inventory-Revised (TCI-R). We found that hostility and childhood sexual abuse, but not impulsivity or other temperament traits, significantly predicted the presence, number and severity of previous suicide attempts. Hostility traits and childhood sexual abuse showed an impact on suicide attempts in BPD. Our results support previous findings indicating that high levels of hostility and having suffered sexual abuse during childhood lead to an increased risk for suicidal behaviour in BPD. © 2013 Elsevier Ireland Ltd.

To: (1) determine the association between Internet addiction and depression, self-reported symptoms of attention deficit and hyperactivity disorder (ADHD), social phobia, and hostility for adolescents; and (2) evaluate the sex differences of association between Internet addiction and the above-mentioned psychiatric symptoms among adolescents. A total of 2114 students (1204 male and 910 female) were recruited for the study. Internet addiction, symptoms of ADHD, depression, social phobia, and hostility were evaluated by the self-report questionnaire. The results demonstrated that adolescents with Internet addiction had higher ADHD symptoms, depression, social phobia, and hostility. Higher ADHD symptoms, depression, and hostility are associated with Internet addiction in male adolescents, and only higher ADHD symptoms and depression are associated with Internet addiction in female students. These results suggest that Internet addiction is associated with symptoms of ADHD and depressive disorders. However, hostility was associated with Internet addiction only in males. Effective evaluation of, and treatment for ADHD and depressive disorders are required for adolescents with Internet addiction. More attention should be paid to male adolescents with high hostility in intervention of Internet addiction.

Negative affect intensity and hostility have both been implicated in alcohol use disorders (AUD) and post-traumatic stress disorder (PTSD) when they occur separately, but have neither been compared nor explored among those with dual diagnosis AUD and PTSD. This study is a secondary analysis designed to compare levels of negative affect intensity and hostility among those with AUD to those with dual diagnosis AUD and PTSD. Participants (n = 113) were recruited from the placebo-controlled groups of two distinct 12-week clinical trials (NCT00342563 and NCT00744055). The Short Affect Intensity Scale and Buss-Durkee Hostility Inventory were administered at weeks 0, 4, 8 and 12 to all study participants to assess negative affect intensity and hostility levels, respectively. Dual diagnosis AUD and PTSD individuals showed significantly higher levels of negative affect intensity and hostility than individuals with single diagnosis AUD. These levels remained relatively stable over the course of the study in spite of all study participants showing clinically significant improvements in AUD severity and PTSD symptomology (for those with dual diagnosis). Our results indicate that individuals with dual diagnosis AUD and PTSD have higher levels of negative affect and higher levels of hostility compared to individuals with single diagnosis AUD. In addition, these heightened levels of negative affect intensity and hostility appear to function somewhat independently of diagnosis severity and symptomology improvement. To our knowledge, this is the first study to compare negative affect intensity and hostility levels between single diagnosis AUD and dual diagnosis AUD and PTSD individuals.

Creating a 'hostile environment for migrants': the British government's use of health service data to restrict immigration is a very bad idea.

Science.gov (United States)

Hiam, Lucinda; Steele, Sarah; McKee, Martin

2018-04-01

In January 2017, the UK Government made public a Memorandum of Understanding (MoU) between the Department of Health, National Health Service (NHS) Digital and the Home Office. This Memorandum allows for the more expedited sharing of a patient's non-clinical data, specifically from the NHS England to the Home Office. The Government justified the MoU as in the 'public interest to support effective immigration enforcement'. In this review, we seek to unpack this justification by providing, first, a background to the MoU, placing it in the context of creating a 'hostile environment' for migrants - a project initially sought by Theresa May in her time as Home Secretary. We then explore the potential impact of data sharing on individual health, public health and on health professionals. We conclude that the MoU could threaten both individual and public health, while placing health professionals in an unworkable position both practically and in terms of their duties to patients around confidentiality. As such, we agree with colleagues' position that it should be suspended, at least until a full consultation and health impact assessment can be carried out.

2017-01-01

The present study examined the relations between child maltreatment and reactive and proactive functions of aggression, and whether hostile attribution biases partially accounted for these associations in a sample of 339 college students (mean age = 19; 51% male). Child maltreatment was associated with reactive, but not proactive, aggression, and instrumental hostile attribution biases accounted for this association. Relational hostile attributions were correlated with both reactive and proactive aggression, but did not play a role in the link between child maltreatment and reactive aggression. PMID:29386881

The relationship between adult reactive and proactive aggression, hostile interpretation bias, and antisocial personality disorder.

Lobbestael, Jill; Cima, Maaike; Arntz, Arnoud

2013-02-01

Reactive aggression (RA) refers to angry responses to provocation or frustration, while proactive aggression (PA) denotes nonemotional, instrumental, and unprovoked aggression. The current study examined personality-related and cognitive correlates of both aggressive types. Respectively, the predictive values of antisocial personality disorder (ASPD), and of hostile interpretation bias, which is the tendency to interpret ambiguous stimuli in a hostile manner, were studied. The sample consisted of n = 37 male adult patients with mixed diagnoses and n = 29 male nonpatients that responded to vignettes and pictures of ambiguous situations, using both open and closed answer formats. ASPD was assessed by means of the Structured Clinical Interview for DSM-IV Axis II disorders (SCID-II), and the Reactive Proactive Questionnaire (RPQ) measured RA and PA. Results showed that although both RA and PA types were predicted by ASPD traits, RA was additionally predicted by a hostile interpretation bias. These findings suggest that reducing hostile bias is a promising avenue for clinical treatment of ASPD-patients high in RA.

Assessment of uncertainties in measurement of pH in hostile environments characteristic of nuclear repositories

1991-10-01

This report focuses on evaluation and characteristics of sputtered thin film pH electrodes which can be used to assess the corrosivity of hot (100 degree C) aqueous solutions present in nuclear repositories. Sputtered thin films have the advantages of high temperature capability, ruggedness, and low cost. The iridium oxide films were found to have a linear, 58 mV/pH, response to changes in pH. They had little hysteresis but drifted approximately 0.2 V over a period of two days exposure to pH 2--12 solutions. The films were found to be insensitive to interference from most ions such as alkali ions but had redox sensitivity to ferri-/ferrocyanide ions. Although special surface treatments were needed for the films for good adherence at 200 degree C the films were not degraded after 20 hours exposure at pH 4, 7, and 10 at 200 degree C. Ruthenium oxide sputtered films performed equally well to the iridium oxide films in parallel tests. The report also contains information on electrochemistry and testing of thin film electrodes and the characterization of the thin films by x-ray photoemission spectroscopy, ultraviolet photoemission spectroscopy, and ion scattering spectroscopy. 123 refs., 29 figs., 7 tabs

With the inexorable increase in the use of mobile devices, wireless connectivity is expected by users anywhere, anytime. In general, this requirement is addressed in office buildings or public locations through the use of Wi-Fi technology but Wi-Fi is not well adapted for use in large experiment halls and complex underground environments, especially those where radiation exposure is an issue, such as the LHC tunnel and experimental caverns. 4G/LTE technology, however, looks to be well adapted to addressing mobility needs in such areas. We report here the studies CERN has undertaken on the use of 4G/LTE in the LHC tunnel, presenting results on the data throughput that can be achieved and discussing issues such as the provision of a consistent user experience.

In adolescent populations worldwide, Internet addiction is prevalent and is often comorbid with depression, hostility, and social anxiety of adolescents. This study aimed at evaluating the exacerbation of depression, hostility, and social anxiety in the course of getting addiction to Internet or remitting from Internet addiction among adolescents. This study recruited 2293 adolescents in grade 7 to assess their depression, hostility, social anxiety and Internet addiction. The same assessments were repeated one year later. The incidence group was defined as subjects classified as non-addicted in the first assessment and as addicted in the second assessment. The remission group was defined as subjects classified as addicted in the first assessment and as non-addicted in the second assessment. The incidence group exhibited increased depression and hostility more than the non-addiction group and the effect of on depression was stronger among adolescent girls. Further, the remission group showed decreased depression, hostility, and social anxiety more than the persistent addiction group. Depression and hostility worsen in the addiction process for the Internet among adolescents. Intervention of Internet addiction should be provided to prevent its negative effect on mental health. Depression, hostility, and social anxiety decreased in the process of remission. It suggested that the negative consequences could be reversed if Internet addiction could be remitted within a short duration. Copyright © 2014 Elsevier Inc. All rights reserved.

The propaganda of extreme hostility: denunciation and the regulation of the group.

Science.gov (United States)

Finlay, W M L

2007-06-01

This paper discusses how those espousing racist or separatist ideologies seek to persuade others to conform to their beliefs. Using examples from Nazi Germany, White Power movements in the USA and the extreme fringes of Zionist politics, it illustrates how notions of identity are linked to positions of hostility, hatred or separatism from other groups. In particular, it describes how those who maintain relations with other groups or who oppose hostility are discounted through accounts of social influence. The effectiveness of this rhetoric in terms of creating climates of social and self-censure, and of silencing dissent in situations of conflict, is discussed.

The Refugees: Threatening or Beneficial? Exploring the Effects of Positive and Negative Attitudes and Communication on Hostile Media Perceptions

Directory of Open Access Journals (Sweden)

Dorothee Arlt

2016-07-01

Full Text Available In the actual debate on refugees in Germany the media’s role was heavily disputed. To understand this controversy, this study examines hostile media perceptions from the audience perspective. Building up on previous research on the hostile media phenomenon and considering literature on pro- and anti-immigrant attitudes, this study explores the effect of positive and negative attitudes towards refugees as well as of mainstream media, social media and interpersonal communication on hostile media perceptions. Using survey data (N=1005 and applying structural equation modelling, several hypotheses on the effects of attitudes and communication variables were tested. The results demonstrate that perceptions of media bias are strongly influenced by people’s negative and positive attitudes towards refugees and the basic hostile media hypothesis was confirmed. Moreover, our findings reveal that the perceived intensity of media coverage on contested aspects of the refugee issue also has an effect on perceptions of hostility. However, the various communication variables did not prove to have direct effects, whereas mainstream media use, social media use, and interpersonal communication with refugees had indirect effects on the hostile media perception.

External built residential environment characteristics include aspects of building design such as types of walls, doors and windows, green spaces, density of houses per unit area, and waste disposal facilities. Neighborhoods that are characterized by poor quality external built environment can contribute to psychosocial stress and increase the likelihood of mental health disorders. This study investigated the relationship between characteristics of external built residential environment and mental health disorders in selected residences of Nakuru Municipality, Kenya. External built residential environment characteristics were investigated for 544 residents living in different residential areas that were categorized by their socioeconomic status. Medically validated interview schedules were used to determine mental health of residents in the respective neighborhoods. The relationship between characteristics of the external built residential environment and mental health of residents was determined by multivariable logistic regression analyses and chi-square tests. The results show that walling materials used on buildings, density of dwelling units, state of street lighting, types of doors, states of roofs, and states of windows are some built external residential environment characteristics that affect mental health of adult males and females. Urban residential areas that are characterized by poor quality external built environment substantially expose the population to daily stressors and inconveniences that increase the likelihood of developing mental health disorders.

We examined direct and indirect pathways from marital hostility to toddler anger/frustration via harsh parenting and parental depressive symptoms, with an additional focus on the moderating role of genetic influences as inferred from birth parent anger/frustration. Participants were 361 linked triads of birth mothers, adoptive parents, and adopted children who were 9 (T1) and 18 (T2) months old across the study period. Results indicated an indirect effect from T1 marital hostility to T2 toddler anger/frustration via T2 parental harsh discipline. Results also indicated that the association between marital hostility and toddler anger was moderated by birth mother anger/frustration. For children whose birth mothers reported high levels of anger/frustration, adoptive parents' marital hostility at T1 predicted toddler anger/frustration at T2. This relation did not hold for children whose birth mothers reported low levels of anger/frustration. The results suggest that children whose birth mothers report elevated frustration might inherit an emotional lability that makes them more sensitive to the effects of marital hostility.

Although research has shown links between family-of-origin violence (FOV), intimate partner violence (IPV), and hostility, research has not examined whether hostility mediates the relationship between FOV and IPV. The current study examined whether hostility mediates FOV and IPV perpetration in 302 men arrested for domestic violence. Results demonstrated that hostility fully mediated the relationship between father-to-participant FOV and physical and psychological IPV, and the relationship between mother-to-participant FOV and physical IPV. Results indicated that hostility fully mediated the relationship between experiencing and witnessing FOV and physical IPV (composite FOV), and partially mediated the relationship between composite FOV and psychological aggression. © The Author(s) 2015.

Maternal attitudinal inflexibility: longitudinal relations with mother-infant disrupted interaction and childhood hostile-aggressive behavior problems.

2009-12-01

: The Personal Attitude Scale (PAS; Hooley, 2000) is a method that is under development for identifying individuals high in Expressed Emotion based on personality traits of inflexibility, intolerance, and norm-forming. In the current study, the goal was to measure the association between this maternal attitudinal inflexibility, early hostile or disrupted mother-infant interactions, and hostile-aggressive behavior problems in the child. In a prospective longitudinal study of 76 low-income mothers and their infants, it was predicted that maternal PAS scores, assessed at child age 20, would be related to difficulties in early observed mother-infant interaction and to hostile-aggressive behavioral difficulties in the child. Results indicated that maternal difficulties in interacting with the infant in the laboratory were associated with maternal PAS scores assessed 20 years later. Hostile-aggressive behavior problems in the child at age five were also predictive of PAS scores of mothers. However, contrary to prediction, these behavior problems did not mediate the association between mother-infant interaction difficulties and maternal PAS scores, indicating that the child's hostile-aggressive behavior problems did not produce the link between quality of early interaction and later maternal attitudinal inflexibility. The current results validate the PAS against observable mother-child interactions and child hostile-aggressive behavior problems and indicate the importance of future work investigating the maternal attitudes that are associated with, and may potentially precede, parent-infant interactive difficulties. These findings regarding the inflexible attitudes of mothers whose interactions with their infants are also disrupted have important clinical implications. First, once the stability of the PAS has been established, this measure may offer a valuable screening tool for the prenatal identification of parents at risk for difficult interactions with their children

The social nature of benevolent sexism and the antisocial nature of hostile sexism: Is benevolent sexism more likely to manifest in public contexts and hostile sexism in private contexts?

Chisango, Tadios; Mayekiso, Thokozile; Thomae, Manuela

Previous research converges on demonstrating that benevolent sexism (BS) is socially approved, whereas hostile sexism (HS) is socially disapproved. We postulated that a sample of married women would be likely to report that their husbands express hostile sexist attitudes and engage in related actions towards them more in private than public contexts, where they lie concealed from public censure. By contrast, the women would report that their husbands would be likely to express benevolent sexist attitudes and engage in related actions more in public than private contexts, where they are reinforced not only by their target (i.e. wife), but also by significant others and the society at large. We tested these hypotheses with a sample of Black, heterosexually married Zimbabwean women (n = 109, mean age = 31.83). Results supported our hypotheses: the women reported hostile sexist attitudes and actions to be more likely to occur in private than public contexts; on the other hand, they reported benevolent sexist attitudes and actions to be more likely in public than private contexts. We conclude that differences in social approval of BS and HS account for these results. © 2014 International Union of Psychological Science.

Iraq and Afghanistan War veterans were grouped by level of posttraumatic stress disorder (PTSD) symptomatology and compared on self-report measures of trait anger, hostility, and aggression. Veterans who screened positive for PTSD reported significantly greater anger and hostility than those in the subthreshold-PTSD and non-PTSD groups. Veterans in the subthreshold-PTSD group reported significantly greater anger and hostility than those in the non-PTSD group. The PTSD and subthreshold-PTSD groups did not differ with respect to aggression, though both groups were significantly more likely to have endorsed aggression than the non-PTSD group. These findings suggest that providers should screen for anger and aggression among Iraq and Afghanistan War veterans who exhibit symptoms of PTSD and incorporate relevant anger treatments into early intervention strategies.

Using built environment characteristics to predict walking for exercise

Directory of Open Access Journals (Sweden)

Siscovick David S

2008-02-01

Full Text Available Abstract Background Environments conducive to walking may help people avoid sedentary lifestyles and associated diseases. Recent studies developed walkability models combining several built environment characteristics to optimally predict walking. Developing and testing such models with the same data could lead to overestimating one's ability to predict walking in an independent sample of the population. More accurate estimates of model fit can be obtained by splitting a single study population into training and validation sets (holdout approach or through developing and evaluating models in different populations. We used these two approaches to test whether built environment characteristics near the home predict walking for exercise. Study participants lived in western Washington State and were adult members of a health maintenance organization. The physical activity data used in this study were collected by telephone interview and were selected for their relevance to cardiovascular disease. In order to limit confounding by prior health conditions, the sample was restricted to participants in good self-reported health and without a documented history of cardiovascular disease. Results For 1,608 participants meeting the inclusion criteria, the mean age was 64 years, 90 percent were white, 37 percent had a college degree, and 62 percent of participants reported that they walked for exercise. Single built environment characteristics, such as residential density or connectivity, did not significantly predict walking for exercise. Regression models using multiple built environment characteristics to predict walking were not successful at predicting walking for exercise in an independent population sample. In the validation set, none of the logistic models had a C-statistic confidence interval excluding the null value of 0.5, and none of the linear models explained more than one percent of the variance in time spent walking for exercise. We did not

In 4 Phase III registration trials (3 in patients with partial seizures, N=1480; 1 in patients with PGTCS, N=163), perampanel administered to patients already receiving 1-3 concomitant antiepileptic drugs (AEDs) demonstrated statistically superior efficacy compared to placebo in reducing seizure frequency. However, use of perampanel in these studies was associated with a risk of psychiatric and behavioral adverse reactions, including aggression, hostility, irritability, anger, and homicidal ideation and threats. The present study is a post hoc analysis of pooled data from these 4 trials to determine if concomitant treatment with levetiracetam and/or topiramate increased the risk of hostility- and aggression-related AEs. Treatment-emergent AEs (TEAEs) were determined using a "Narrow & Broad" search based on the Medical Dictionary for Regulatory Activities (MedDRA) standard MedDRA query (SMQ) for hostility- and aggression-related events. The rate of hostility- and aggression-related TEAEs was observed to be similar among perampanel-treated patients: a) receiving levetiracetam (N=340) compared to those not receiving levetiracetam (N=779); b) receiving topiramate (N=223) compared to those not receiving topiramate (N=896); and c) receiving both levetiracetam and topiramate (N=47) compared to those not receiving levetiracetam and topiramate (N=1072). Severe and serious TEAEs related to hostility and aggression were rare and occurred at a similar rate regardless of concomitant levetiracetam and/or topiramate therapy. Taken together, these results suggest that concomitant treatment with levetiracetam and/or topiramate has no appreciable effect on the occurrence of hostility- or aggression-related TEAEs in patients receiving perampanel.

2015-12-01

This study investigated the effects of trait-level hostility, interface types, and character identification on aggressive thoughts and overall game experience after playing a violent video game. Results showed that the mapping interface made participants with high trait-level hostility more readily accessible to aggressive contracts, yet it did not have any significant impact for participants with low trait-level hostility. Participants with low trait-level hostility reported more positive game experience in the mapping interface condition, while participants with high trait-level hostility in the same condition reported more negative game experience. Results also indicated that character identification has moderating effects on activating aggressive thoughts and mediating effects on overall game experience. Implications regarding possible ways of reducing potentially negative outcomes from violent games are discussed.

Modern Instrumentation of a Historical Landslide to Understand Dynamic Processes Governing Slope Movement in a Hostile Environment.

Science.gov (United States)

Johnson, K. A.

2017-12-01

The Milepost 6.2 Landslide on Many Glacier Road in Glacier National Park, Montana, has been moving since construction of the roadway in the early 1900's. Movement of the slide has a direct impact on Park operations and requires regrading and reconstruction of the road on a nearly annual basis. Prior attempts to stabilize the slope were not effective. Despite the history of this slide, very little quality data was available to delineate the depth and shape of the slide or the groundwater pressures that influence slope stability due to only seasonal data collection and a hostile winter environment. Landslide dynamics are further complicated where the toe of the slide becomes submerged seasonally by Lake Sherburne. In addition, due to irrigation use the lake levels fluctuate rapidly with seasonal rise and drops commonly greater than 30 feet in elevation. Five Shape Accelerometer Array inclinometers (SAAs) were installed to depths between 60 and 200 feet, along with 10 vibrating wire piezometers, one tipping bucket rain gauge, and onsite data acquisition system with a real-time satellite communication link enabling year-round data collection. Measurements of groundwater pressures and slide dynamics were used to develop a well constrained 2-D dynamic model of slide movement. Movement is controlled by clayey zones in glacial till deposits that mantle the valley slopes, along with water pressures from groundwater in the slope and fluctuating lake levels at the toe of the slope. The SAAs document slide plane locations and rates of slide movement as it changes through the year in response to the dynamic hydrologic setting. SAAs document sliding of over 3 feet and continue to operate and generate additional data. The data collected enabled the design of an extensive horizontal drain system to lower the groundwater pressures and stabilize the slope. Continuous year-round monitoring allowed comparison of slope movement in response to changes in lake elevation and precipitation

Full Text Available If teachers and teacher educators are willing to support the learning of students, it is important for them to learn what motivates students to engage in learning. Students have their own preferences on design characteristics of powerful learning environments in vocational education. We developed an instrument - the Inventory Powerful Learning Environments in Vocational Education - to measure students’ preferences on characteristics of powerful learning environments in vocational education. We investigated whether student preferences on the design of their learning environments are in line with what is described in the literature as beneficial for learning. Data of 544 students show that the preferences of students support most characteristics of PLEs in vocational education. Looking through the eyes of students, teachers have to challenge their students and encourage them to take their learning in their own hands. Adaptive learning support is needed. Remarkable, students do not prefer having reflective dialogues with teachers or peers.

The DIII-D Computing Environment: Characteristics and Recent Changes

International Nuclear Information System (INIS)

McHarg, B.B. Jr.

1999-01-01

The DIII-D tokamak national fusion research facility along with its predecessor Doublet III has been operating for over 21 years. The DIII-D computing environment consists of real-time systems controlling the tokamak, heating systems, and diagnostics, and systems acquiring experimental data from instrumentation; major data analysis server nodes performing short term and long term data access and data analysis; and systems providing mechanisms for remote collaboration and the dissemination of information over the world wide web. Computer systems for the facility have undergone incredible changes over the course of time as the computer industry has changed dramatically. Yet there are certain valuable characteristics of the DIII-D computing environment that have been developed over time and have been maintained to this day. Some of these characteristics include: continuous computer infrastructure improvements, distributed data and data access, computing platform integration, and remote collaborations. These characteristics are being carried forward as well as new characteristics resulting from recent changes which have included: a dedicated storage system and a hierarchical storage management system for raw shot data, various further infrastructure improvements including deployment of Fast Ethernet, the introduction of MDSplus, LSF and common IDL based tools, and improvements to remote collaboration capabilities. This paper will describe this computing environment, important characteristics that over the years have contributed to the success of DIII-D computing systems, and recent changes to computer systems

Hostile and benevolent reactions toward pregnant women: complementary interpersonal punishments and rewards that maintain traditional roles.

2007-11-01

A naturalistic field study investigated behavior toward pregnant (vs. nonpregnant) women in nontraditional (job applicant) and traditional (store customer) roles. Female confederates, who sometimes wore a pregnancy prosthesis, posed as job applicants or customers at retail stores. Store employees exhibited more hostile behavior (e.g., rudeness) toward pregnant (vs. nonpregnant) applicants and more benevolent behavior (e.g., touching, overfriendliness) toward pregnant (vs. nonpregnant) customers. A second experiment revealed that pregnant women are especially likely to encounter hostility (from both men and women) when applying for masculine as compared with feminine jobs. The combination of benevolence toward pregnant women in traditional roles and hostility toward those who seek nontraditional roles suggests a system of complementary interpersonal rewards and punishments that may discourage pregnant women from pursuing work that violates gender norms.

The effects of racial stressors and hostility on cardiovascular reactivity in African American and Caucasian men.

Science.gov (United States)

Fang, C Y; Myers, H F

2001-01-01

This study examined the effects of race-related stressors and hostility on cardiovascular reactivity in 31 African American and 31 Caucasian men. Participants viewed 3 film excerpts that depicted neutral, anger-provoking (but race-neutral), and racist situations. Participants exhibited significantly greater diastolic blood pressure reactivity to anger-provoking and racist stimuli compared with neutral stimuli. In addition, high hostility was associated with higher recovery systolic and diastolic blood pressure levels after exposure to the films. Although the results failed to confirm previous reports of greater reactivity to racism in African Americans, the findings suggest that diastolic blood pressure levels may remain elevated after exposure to racist stimuli. These results indicate that even indirect exposure to interpersonal conflict elicits significant reactivity, which can persist after exposure to the stressor, especially among high-hostile men.

However, effective management of hostility and/or agitation symptoms may prevent patients from becoming violent. This analysis investigated the efficacy of the antipsychotic asenapine on hostility and agitation in patients with bipolar I disorder.Methods: Data were pooled from three randomized, double-blind, placebo-controlled, Phase III trials of asenapine in adults with manic or mixed episodes of bipolar I disorder (NCT00159744, NCT00159796, and NCT00764478. Post hoc analyses assessed the changes from baseline to day 21 on the Young Mania Rating Scale (YMRS and the Positive and Negative Syndrome Scale (PANSS hostility-related item scores in asenapine- or placebo-treated patients with at least minimal or mild symptom severity and on the PANSS-excited component (PANSS-EC total score in agitated patients. Changes were adjusted for improvements in overall mania symptoms to investigate direct effects on hostility.Results: Significantly greater changes in favor of asenapine versus placebo were observed in YMRS hostility-related item scores (irritability: least squares mean difference [95% confidence interval] =–0.5 [–0.87, –0.22], P=0.001; disruptive–aggressive behavior: –0.7 [–0.99, –0.37], P<0.0001, PANSS hostility item score (–0.2 [–0.44, –0.04]; P=0.0181, and PANSS-EC total score (–1.4 [–2.4, –0.4]; P=0.0055.

Sensor data fusion is the combination of two or more information streams. We describe a sensor that fuses sonar and visual data to create a three dimensional(3D) model of the environment. A laser slit beam from laser source is slitted by a set of cylindrical lenses and the line image of the slit beam on the object is used to estimate the object parameters. Surface modeling routine and transferring the resulting surfaces to a IGRIP via a standard graphic software. The results suggest that the information of the multisensor system is significant compared to each sensor acting alone and this performance of this environmental modeling scheme would be suitable for reconstruction of data.

The impact of violent video games (VVGs) on youth remains unclear given inconsistent results in past literature. Most previous experimental studies have been done with college students, not youth. The current study examined the impact of VVGs in an experimental study of teens (12-18). Participants were randomized to play either a violent or non-violent video game. Teens also reported their levels of stress and hostility both before and after video game play. Hostility levels neither decreased nor increased following violent game play, and Bayesian analyzes confirmed that results are supportive of the null hypothesis. By contrast, VVG exposure increased stress, but only for girls. The impact of VVGs on teen hostility is minimal. However, players unfamiliar with such games may find them unpleasant. These results are put into the context of Uses and Gratifications Theory with suggestions for how medical professionals should address the issue of VVG play with concerned parents.

Feeling and thinking of others: affective and cognitive empathy and emotion comprehension in prosocial/hostile preschoolers.

2012-01-01

This study aims at investigating the affective and cognitive components of empathy in relation to both emotion comprehension and prosocial/hostile behaviors in preschoolers. A total of 219 children (54% boys; aged between 3 and 6: mean age 4.10) and 20 teachers (two for each class: group A and group B) took part in this research. Pupils' empathy and hostile/prosocial roles were assessed by teacher reports [Belacchi and Farina, 2010] and children's emotion comprehension by a nonverbal test [Test of Emotion Comprehension: Pons and Harris, 2000; adapted by Albanese and Molina; 2008]. As expected, the results showed a significant influence of gender, with girls being more empathic than boys, according to all of the teachers' perception. Contrary to our expectations, no systematic age influence emerged. Regarding the relations of children's emotion comprehension with both empathy measures and their prosocial/hostile attitudes, we have found: (1) a low significant relation with the total empathy measure, according to all the teachers, but with the cognitive empathy only according to teachers B; (2) a robust negative relationship of both affective and cognitive empathy with Hostile roles and with Outsider role, contrary to a positive correlation of only affective empathy with Prosocial roles. No relationships emerged between empathy measures and Victim role. © 2012 Wiley Periodicals, Inc.

This study explored the possibility that an increase in state narcissism would foster aggressive responding by increasing anger and hostile attributional bias following unexpected provocation among 162 college students from China. We created a guided-imagination manipulation to heighten narcissism and investigated its effects on anger, aroused hostile attribution bias, and aggressive responses following a provocation with a 2 (narcissism/neutral manipulation) × 2 (unexpected provocation/positive evaluation condition) between-subjects design. We found that the manipulation did increase self-reported state narcissism. The increase in state narcissism in turn heightened aggression, and this relation was mediated by increased anger. Regardless of the level of state narcissism, individuals were more aggressive after being provoked and this effect of provocation was mediated by hostile attributional bias. The findings indicate that narcissism can be temporarily heightened in a nonclinical sample of individuals, and that the effect of state narcissism on aggression is mediated by anger. Differences between state and trait narcissism and possible influences of culture are discussed. Aggr. Behav. 42:333-345, 2016. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

The Behavioral Health and Performance (BHP) Element addresses human health risks in the NASA Human Research Program (HRP), including the Risk of Adverse Behavioral Conditions and the Risk of Psychiatric Disorders. BHP supports and conducts research to help characteristics and mitigate the Behavioral Medicine risk for exploration missions, and in some instances, current Flight Medical Operations. The Behavioral Health and Performance (BHP) Element identified research gaps within the Behavioral Medicine Risk, including Gap BMed6: What psychosocial characteristics predict success in an isolated, confined environment (ICE)? To address this gap, we conducted an extensive and exhaustive literature review to identify the following: 1) psychosocial characteristics that predict success in ICE environments; 2) characteristics that are most malleable; and 3) specific countermeasures that could enhance malleable characteristics.

A revised version of the three-factor theory of child abuse (Lesnik-Oberstein, Cohen, & Koers, 1982) is presented. Further, we report on a research designed to test three main hypotheses derived from Factor I (1) (a high level of hostility in abusive parents) and its sources. The three main hypotheses are: (1) that psychologically abusive mothers have a high level of hostile feelings (Factor I); (2) that the high level of hostile feelings in abusive mothers is associated with low marital coping skills (resulting in affectionless, violent marriages), a negative childhood upbringing (punitive, uncaring, over controlling), a high level of stress (objective stress), and a high level of strain (low self-esteem, depression, neurotic symptoms, social anxiety, feelings of being wronged); and (3) that maternal psychological child abuse is associated with low marital coping skills, a negative childhood upbringing, a high level of stress and a high level of strain. Forty-four psychologically abusing mothers were compared with 128 nonabusing mothers on a variety of measures and were matched for age and educational level. All the mothers had children who were hospitalized for medical symptoms. The three hypotheses were supported, with the exception of the component of hypothesis 2 concerning the association between objective stress and maternal hostility. The positive results are consistent with the three-factor theory.

Hoffman, C D; Moon, M

1999-12-01

Women's (N = 364) personal characteristics and gender role attitudes were examined in relation to their support for father involvement with children. The respondents completed measures of trust, attitudes toward women, hostility, self-esteem, and father involvement. Nontraditional gender role attitudes, positive ratings of their own interpersonal trust, and low hostility toward men were predictive of the respondents' support for father involvement. Participant demographics (including age, marital status, and number of children) were unrelated to their views of father involvement. Results indicate the importance of considering the characteristics and attitudes women bring to the co-parental relationship in the examination of factors influencing father involvement with children. Findings are discussed within the context of mothers' primary child-care and gatekeeping roles.

The aim of this study is to examine characteristics of the nursing practice environment associated with lower RN turnover. Identifying characteristics of the practice environment that contribute to lower RN turnover is important for meeting the national quality strategy priority of reducing healthcare costs. Data from 1002 adult care units in 162 National Database of Nursing Quality Indicators participating hospitals were analyzed using multivariate linear regression. The Practice Environment Scale of the Nursing Work Index was used to measure practice environment characteristics. RN turnover was measured at the unit level. Nursing units with higher overall ratings of the nursing practice environment had lower rates of RN turnover. Units with higher RN perceived staffing and resource adequacy experienced significantly lower RN turnover. Unit managers and hospital administrators should consider RN perception of staffing and resource adequacy and the overall practice environment when developing targeted strategies for decreasing RN turnover.

Lisco, Claire G; Parrott, Dominic J; Tharp, Andra Teten

2012-11-01

Research indicates that men's heavy episodic drinking is a significant risk factor for their perpetration of sexual aggression toward intimate partners. The aim of this investigation was to examine how hostile sexism (i.e., antipathy toward women) and benevolent sexism (i.e., subjectively positive, yet patriarchal, views of women) influence the relation between men's heavy episodic drinking and their perpetration of sexual aggression toward intimate partners. Participants were 205 heterosexual drinking men who completed self-report measures of quantity of alcohol consumption during the past 12 months, hostile sexism, and sexual aggression toward an intimate partner during the past 12 months. Men's heavy episodic drinking was positively associated with sexual aggression perpetration toward intimate partners amongst men who endorsed high, but not low, levels of hostile sexism. No such interactive effect emerged for men's endorsement of benevolent sexism. These results have important implications for understanding cumulative risk factors for the perpetration of sexual aggression toward intimates. Copyright © 2012 Elsevier Ltd. All rights reserved.

Automatic early warning systems for the environment

Directory of Open Access Journals (Sweden)

Lesjak Martin

2003-01-01

Full Text Available Computerized, continuous monitoring environmental early warning systems are complex networks that merge measurements with the information technology. Accuracy, consistency, reliability and data quality are their most important features. Several effects may disturb their characteristics: hostile environment, unreliable communications, poor quality of equipment nonqualified users or service personnel. According to our experiences, a number of measures should be taken to enhance system performances and to maintain them at the desired level. In the paper, we are presenting an analysis of system requirements, possible disturbances and corrective measures that give the main directives for the design, construction and exploitation of the environmental early warning systems. Procedures which ensure data integrity and quality are mentioned. Finally, the contemporary system approach based on the LAN/WAN network topology with Intranet/Internet software is proposed, together with case descriptions of two already operating systems, based on computer-network principle.

Hostile behavior during marital conflict alters pituitary and adrenal hormones.

Malarkey, W B; Kiecolt-Glaser, J K; Pearl, D; Glaser, R

1994-01-01

We evaluated hormonal changes and problem-solving behaviors in 90 newlywed couples who were admitted to a hospital research unit for 24 hours. The subjects were selected on the basis of stringent mental and physical health criteria, and admissions were scheduled during the follicular phase of the woman's menstrual cycle. For frequent, unobtrusive endocrine sampling during the interaction tasks, a long polyethylene tube was attached to a heparin well, allowing nurses to draw blood samples at set intervals, out of subjects' sight. Five blood samples were obtained before, during, and after a 30-minute structured problem-solving or conflict task. The conflict session was recorded on videotapes that were later scored for problem-solving behaviors using the Marital Interaction Coding System (MICS). Marital conflict and MICS-coded hostile or negative behavior during conflict was closely linked to changes in serum hormonal levels across five of the six hormones we studied, in spite of the high marital satisfaction of our newlywed couples and the healthy lifestyles demanded by our exclusion criteria. Hostile behavior was associated with decreased levels of prolactin (PRL) and increases in epinephrine (EPI), norepinephrine (NEPI), ACTH, and growth hormone (GH), but not cortisol. These data suggest that the endocrine system may be an important mediator between personal relationships and health.

Copahue Geothermal System: A Volcanic Environment with Rich Extreme Prokaryotic Biodiversity.

The Copahue geothermal system is a natural extreme environment located at the northern end of the Cordillera de los Andes in Neuquén province in Argentina. The geochemistry and consequently the biodiversity of the area are dominated by the activity of the Copahue volcano. The main characteristic of Copahue is the extreme acidity of its aquatic environments; ponds and hot springs of moderate and high temperature as well as Río Agrio. In spite of being an apparently hostile location, the prokaryotic biodiversity detected by molecular ecology techniques as well as cultivation shows a rich and diverse environment dominated by acidophilic, sulphur oxidising bacteria or archaea, depending on the conditions of the particular niche studied. In microbial biofilms, found in the borders of the ponds where thermal activity is less intense, the species found are completely different, with a high presence of cyanobacteria and other photosynthetic species. Our results, collected during more than 10 years of work in Copahue, have enabled us to outline geomicrobiological models for the different environments found in the ponds and Río Agrio. Besides, Copahue seems to be the habitat of novel, not yet characterised autochthonous species, especially in the domain Archaea.

Reading activity is a part of daily learning activities that are usually done by college students and takes place in the facilities that are provided by the campus. However, students tend to have a perception of a particular location that is considered appropriate with the activities undertaken. This study identified students’ perceptions of reading space characteristics in campus environment which are considered able to accommodate reading activity. Exploratory qualitative research methods were used to collect data from selected types of space and the reasons for the students in choosing the specifics space to do their reading. The results showed that students do not only use library facilities as a support unit of academic activities. This study found that students tend to use some places with non-library function, such as students’ union room, hallway, and classroom. Students perceive reading space by its physical and social characteristics. The physical consist of ambiance, quiet place, tranquility, availability of facilities, the level of coolness, lighting, location accessibility, connection with nature, convenience furniture, air quality, aesthetics, the flexibility of activities, the crowd of place, the level of shade, outdoor, ownership, and indoor. While the social characteristics of the reading space are to have privacy, favorable reading position, and the presence of others.

Popinako A.V.

2014-07-01

Full Text Available Based on the analysis of psychosocial models of alcoholism and depression the general and specific factors of occurrence and course of illness are identified in the present study. The authors put forward hypotheses regarding the mechanisms of activation of psychological addiction to alcohol as an ineffective coping strategy. The necessity of empirical research needed to refine the techniques and targets of patient care within the psychiatric and psychological care is justified. The results of the pilot study show that depressed patients who are subject to alcohol dependence feature marked distress in interpersonal relations, coupled with hostility and aim at gaining profit and pleasure by manipulating other people. These patients are hostile to others, while in interpersonal relationships personal safety is important to them, so they may be more likely to resort to manipulation. In their attitudes with respect to health the communication of these patients is characterized by hedonistic tendencies and histrionic traits in interpersonal contacts.

Disruption in the parent-child relationship is a commonly hypothesized risk factor through which maternal depression may increase risk for offspring psychopathology. However, maternal depression is commonly accompanied by other psychopathology, including antisocial behaviour. Few studies have examined the role of co-occurring psychopathology in depressed mothers. Using a longitudinal study of offspring of mothers with recurrent depression, we aimed to test whether maternal warmth/hostility mediated links between maternal depression severity and child outcomes, and how far direct and indirect pathways were robust to controls for co-occurring maternal antisocial behaviour. Mothers with a history of recurrent major depressive disorder and their adolescent offspring (9-17 years at baseline) were assessed three times between 2007 and 2010. Mothers completed questionnaires assessing their own depression severity and antisocial behaviour at Time 1 (T1). The parent-child relationship was assessed using parent-rated questionnaire and interviewer-rated 5-min speech sample at Time 2 (T2). Offspring symptoms of depression and disruptive behaviours were assessed using the Child and Adolescent Psychiatric Assessment at Time 3 (T3). Maternal hostility and warmth, respectively, mediated the association between maternal depression severity and risk for offspring psychopathology. However, the effects were attenuated when maternal antisocial behaviour was included in the analysis. In tests of the full theoretical model, maternal antisocial behaviour predicted both maternal hostility and low warmth, maternal hostility predicted offspring disruptive behaviour disorder symptoms, but not depression, and maternal warmth was not associated with either child outcome. Parenting interventions aimed at reducing hostility may be beneficial for preventing or reducing adolescent disruptive behaviours in offspring of depressed mothers, especially when depressed mothers report co

Glaciers and Ice Sheets As Analog Environments of Potentially Habitable Icy Worlds

Eva Garcia-Lopez

2017-07-01

Full Text Available Icy worlds in the solar system and beyond have attracted a remarkable attention as possible habitats for life. The current consideration about whether life exists beyond Earth is based on our knowledge of life in terrestrial cold environments. On Earth, glaciers and ice sheets have been considered uninhabited for a long time as they seemed too hostile to harbor life. However, these environments are unique biomes dominated by microbial communities which maintain active biochemical routes. Thanks to techniques such as microscopy and more recently DNA sequencing methods, a great biodiversity of prokaryote and eukaryote microorganisms have been discovered. These microorganisms are adapted to a harsh environment, in which the most extreme features are the lack of liquid water, extremely cold temperatures, high solar radiation and nutrient shortage. Here we compare the environmental characteristics of icy worlds, and the environmental characteristics of terrestrial glaciers and ice sheets in order to address some interesting questions: (i which are the characteristics of habitability known for the frozen worlds, and which could be compatible with life, (ii what are the environmental characteristics of terrestrial glaciers and ice sheets that can be life-limiting, (iii What are the microbial communities of prokaryotic and eukaryotic microorganisms that can live in them, and (iv taking into account these observations, could any of these planets or satellites meet the conditions of habitability? In this review, the icy worlds are considered from the point of view of astrobiological exploration. With the aim of determining whether icy worlds could be potentially habitable, they have been compared with the environmental features of glaciers and ice sheets on Earth. We also reviewed some field and laboratory investigations about microorganisms that live in analog environments of icy worlds, where they are not only viable but also metabolically active.

Full Text Available Aircraft aluminum alloy is easy to initiate pitting corrosion in the service environment, the pitting corrosion topography characteristics could directly affect the fatigue mechanical property of structure material. In order to obtain the pitting corrosion topography characteristics of LC4 aluminum alloy in the service environment, the accelerated corrosion test was carried out along the accelerated corrosion test environment spectrum which imitated the service environment spectrum, and the corrosion topography characteristic parameters of corrosion pit depth H,corrosion pit surface length L and corrosion pit surface width W were defined respectively. During the corrosion test process,the three parameters of typical corrosion pit were successively measured in different equivalent corrosion years for obtaining the corrosion pit damage size data, then the data were analysed through the statistics method and fractal theory. Further more in order to gain the pit topography characteristics in the same equivalent corrosion year and the topography evolution laws during different equivalent corrosion years were gained. The analysis results indicate that LC4 aluminum alloy corrosion pit topography characteristics in the service environment include the following:firstly, the pit topography characteristic parameters conform to the lognormal distributions in the same equivalent corrosion years; secondly,the pit topography characteristic parameters gradually reflect the fractal feature in accordance with the equivalent corrosion year increment, and the pits tend to be shallow, long and moderate wide topography character.

2014-05-01

Full Text Available The article examines Slovenian translations of military jargon in the non-fiction novel Hostile Waters. In the introductory part, jargon is presented as a linguistic category as well as its main features in the novel. Next, select examples from the original text are compared to their Slovenian equivalents. The focus is on collocations and lexically dense nominal phrases. The comparison finds that most translation shifts in the target text occur because of incorrect interpretation of technical jargon expressions in the original. As a result, the target text reader perceives certain situations differently than the source text reader.

Using data from 195 dyads of mothers and children (age range = 8–12 years; M = 10.63) in four countries (China, India, the Philippines, and Thailand), this study examined children’s perceptions of maternal hostility as a mediator of the links between physical discipline and harsh verbal discipline and children’s adjustment. Both physical discipline and harsh verbal discipline had direct effects on mothers’ reports of children’s anxiety and aggression; three of these four links were mediated by children’s perceptions of maternal hostility. In contrast, there were no significant direct effects of physical discipline and harsh verbal discipline on children’s reports of their own anxiety and aggression. Instead, both physical discipline and harsh verbal discipline had indirect effects on the outcomes through children’s perceptions of maternal hostility. We identified a significant interaction between perceived normativeness and use of harsh verbal discipline on children’s perception of maternal hostility, but children’s perception of the normativeness of physical discipline did not moderate the relation between physical discipline and perceived maternal hostility. The effects of harsh verbal discipline were more adverse when children perceived that form of discipline as being nonnormative than when children perceived that form of discipline as being normative. Results are largely consistent with a theoretical model positing that the meaning children attach to parents’ discipline strategies is important in understanding associations between discipline and children’s adjustment, and that cultural context is associated with children’s interpretations of their parents’ behavior.

Erik Lykke Mortensen

2012-01-01

Full Text Available Certain personality traits are likely to be associated with stress and distress through the lifespan, and as a consequence these traits may influence the rate of age-related cognitive decline. The present study uses data from the Glostrup 1914 cohort to analyze potential effects of personality on decline in general intelligence over a 30-year period. The Minnesota Multiphasic Personality Inventory was administered at a 50-year baseline exam, and from this inventory the Obvious Depression Scale and an abbreviated version of the Cook-Medley Hostility Scale were derived. At the 50-year baseline and at the 60-, 70-, and 80-year followups the full version of Wechsler's Adult Intelligence Scale (WAIS was administered to 673, 513, 136, and 184 participants. Mixed effects statistical models were used to evaluate both the effect of the personality scores on level of intelligence and the interaction between the personality scores and the time since followup. Analyses were adjusted for demographic background and a wide range of lifestyle factors. Both obvious depression and hostility were negatively associated with level of intelligence, but personality scores did not influence rate of decline in general intelligence.

Martinez-Pecino, Roberto; Durán, Mercedes

2016-04-25

Cyberbullying is attracting social, political, and academic interest as the use of electronic devices such as computers and mobile phones by young people has increased dramatically. However, little is known about the factors involved in their perpetration, particularly in the context of college students' dating relationships. The aim of this study is to examine the involvement of college students in cyberbullying in the context of their dating relationships and to explore the impact of sexism on males' cyberbullying of their girlfriends. Participants are 219 undergraduate students from a university in the south of Spain. Results showed that 48.4% of participants reported having bullied their partners during the last year via mobile phone and 37.5% via Internet. Males reported a greater extent of cyberbullying of their girlfriends through both means. Regression analyses indicated that males' levels of hostile sexism are related to males' cyberbullying of their girlfriends. These findings suggest a modernization in the forms of violence toward women among college students and also expand current literature by revealing the influence of participants' hostile sexism on this type of cyber aggression against women in dating relationships. © The Author(s) 2016.

2016-01-01

Our team is specialized in ultrasonic measurements in hostile environment especially under high temperatures. There is a need for acoustic transducers capable of continuous measurement at temperatures up to 700°C. To improve the performances of acoustic sensors we focus our works on the realisation and characterisation of transducer backings able to operate under very high temperature. Commercially, they are produced by the incorporation of tungsten powder in a plastic matrix, which limits the working temperature. The realisation of ultrasonic transducers for non-destructive measures at high temperatures requires adequate materials, manufacturing and assembly processes. To produce the backings, composites were made using very ductile metals such as tin and tungsten. These composites are manufactured by uniaxial hot pressing. First, we studied the influence of temperature and pressure on the densification of tin pellets. Then, several specimens made of tin/W were made and characterised by measuring the specific weight, speed and attenuation of sound. The acoustic measures were realised by ultrasonic spectroscopy. This test-bench was designed and tested on control samples of PMMA and on standard backings (epoxy / tungsten). (paper)

Copahue Geothermal System: A Volcanic Environment with Rich Extreme Prokaryotic Biodiversity

María Sofía Urbieta

2015-07-01

Full Text Available The Copahue geothermal system is a natural extreme environment located at the northern end of the Cordillera de los Andes in Neuquén province in Argentina. The geochemistry and consequently the biodiversity of the area are dominated by the activity of the Copahue volcano. The main characteristic of Copahue is the extreme acidity of its aquatic environments; ponds and hot springs of moderate and high temperature as well as Río Agrio. In spite of being an apparently hostile location, the prokaryotic biodiversity detected by molecular ecology techniques as well as cultivation shows a rich and diverse environment dominated by acidophilic, sulphur oxidising bacteria or archaea, depending on the conditions of the particular niche studied. In microbial biofilms, found in the borders of the ponds where thermal activity is less intense, the species found are completely different, with a high presence of cyanobacteria and other photosynthetic species. Our results, collected during more than 10 years of work in Copahue, have enabled us to outline geomicrobiological models for the different environments found in the ponds and Río Agrio. Besides, Copahue seems to be the habitat of novel, not yet characterised autochthonous species, especially in the domain Archaea.

Luiz Felipe Sales Maurício

Full Text Available ABSTRACT Objective: assess the autonomy, control over environment, and organizational support of nurses' work process and the relationships between physicians and nurses in critical care units. Method: cross-sectional study conducted with 162 nurses working in the intensive care units and emergency service of a university hospital. The workers' satisfaction with their work environment was assessed using Brazilian Nursing Work Index - Revised, translated and adapted for the Brazilian culture. Results: average age was 31.6 ± 3.9 years; 80.2% were women; 68.5% Caucasians and 71.6% worked in intensive care units. The nurses considered autonomy (2.38 ± 0.64 and their relationship with physicians (2.24 ± 0.62 to be characteristics of the work environment that favored professional practice. Control over environment (2.78 ± 0.62 and organizational support (2.51 ± 0.54, however, were considered to be unfavorable. No statistically significant differences were found between the units based on the scores obtained by the professionals on the Brazilian Nursing Work Index - Revised. Conclusion: autonomy, relationship between physicians and nurses, and organizational support were considered by the units to be characteristics that favored nurses' professional practices. On the other hand, control over environment and organizational support were considered unfavorable.

The London Spikes Controversy: Homelessness, Urban Securitisation and the Question of ‘Hostile Architecture’

Directory of Open Access Journals (Sweden)

James Petty

2016-03-01

Full Text Available This article examines an ostensibly new feature of the securitised urban landscape: ‘hostile architecture’. Following controversy in 2014 London over ‘anti-homeless spikes’– metal studs implanted at ground level designed to discourage the homeless from sleeping in otherwise unrestricted spaces – certain visible methods of environmental social control were temporarily subject to intense public scrutiny and debate. While contests over public and urban spaces are not new, the spikes controversy emerged in the context of broader socio-political and governmental shifts toward neoliberal arrangements. Using the spikes issue as a case study, I contextualise hostile architecture within these broader processes and in wider patterns of urban securitisation. The article then offers an explanatory framework for understanding the controversy itself. Ultimately the article questions whether the public backlash against the use of spikes indicates genuine resistance to patterns of urban securitisation or, counterintuitively, a broader public distaste for both the homeless and the mechanisms that regulate them.

Suicide rates are higher in East-Asians than other populations, and especially high in Koreans. However, little is known about suicidality risk and melancholic features in Asian patients with major depressive disorder (MDD). Drug-free MDD outpatients were included from 13 centers across five ethnicities consisting of Chinese (n=290), Korean (n=101), Thai (n=102), Indian (n=27), and Malay (n=27). All were interviewed using the Mini-International Neuropsychiatric Interview (M.I.N.I.), the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Symptoms Checklist 90-Revised (SCL-90-R). Of 547 subjects, 177 MDD patients showed melancholic features (32.4%). These melancholic MDD patients revealed significantly higher suicidality risk (pdepression (pdifference in higher hostility. Adjusted odds ratios of melancholic features and hostility for moderate to high suicidality risk were 1.79 (95% CI=1.15-2.79) and 2.45 (95% CI=1.37-4.38), after adjusting for age, sex, education years, and depression severity. Post-hoc analyses showed that suicidality risk was higher in Korean and Chinese than that of Thai, Indian and Malay in MDD subjects with melancholic features, although depression severity showed no significant differences among the ethnicities. Suicidality risk is associated with both melancholic features and hostility and it shows cross-ethnic differences in Asian MDD patients, independent of depression severity.

Hostility/anger as a mediator between college students' emotion regulation abilities and symptoms of depression, social anxiety, and generalized anxiety.

Science.gov (United States)

Asberg, Kia

2013-01-01

Internalizing problems are common among college students and have been linked consistently to deficits in emotion regulation (ER). Also, hostility/anger (animosity toward others, phenomenological aspect of anger) is an important feature of internalizing problems, but has received limited attention as a mediator between ER and outcomes. Results (N = 160) indicated that although college students' ER abilities corresponded with all three types of internalizing symptoms, hostility/anger mediated fully the relationship for symptoms of depression and social anxiety, but not generalized anxiety (GAD). The stronger interpersonal aspect inherent in depression and social anxiety relative to GAD may in part explain findings, but findings must be viewed in lieu of limitations, which include self-report, a non-clinical sample, and a cross-sectional design. Overall, hostility/anger may be important to address in interventions and programs aimed at reducing internalizing problems, especially among those who demonstrate ER deficits and are prone to depression and social anxiety.

Distrustful, Conventional, Entitled, and Dysregulated: PID-5 Personality Facets Predict Hostile Masculinity and Sexual Violence in Community Men.

Russell, Tiffany D; King, Alan R

2017-01-01

Psychopathy and narcissism are known predictors of sexual violence, but they are broad personality constructs with limited utility in intervention and prevention efforts. The Personality Inventory for DSM-5 (PID-5) assesses 25 specific personality facets residing in five higher order domains. The goal of this research was to test the PID-5 in a sexual aggression model, which also included hostile masculinity, juvenile delinquency, and five sexual assault indices. A nationwide sample of adult men ( N = 512) completed the online survey. Hostile masculinity and juvenile delinquency were expected to have direct paths to sexual violence in a structural equation model. Hostile masculinity was also hypothesized as a mediator between sexual violence and PID-5 facets related to narcissism and psychopathy. These hypotheses were largely supported. Overall, 29.5% of men reported perpetrating sexual violence at least once, and 24.2% reported multiple assaults. In the sexually violent sample, 45.7% endorsed completed rape as their most severe act. PID-5 Suspiciousness, Cognitive and Perceptual Dysregulation, Grandiosity, and a lack of Eccentricity emerged as indirect predictors of sexual violence. These PID-5 facets were mediated by hostile masculinity, which had a reliable path to sexual violence. Juvenile delinquency had a direct and indirect path to sexual assault. The model accounted for 48% of the variance in latent sexual violence, and the five sexual violence index R 2 s ranged from .53 to .82. This research adds specificity to sexual violence models by demonstrating the underlying maladaptive personality trait structures associated with sexual assault. It also provides a more precise personality profile for clinical use and prevention programs.

Virtual-reality solutions have successfully been used to train distributed teams. This study aimed to investigate the correlation between user characteristics and sense of presence in an online virtual-reality environment where distributed teams are trained. A greater sense of presence has the potential to make training in the virtual environment more effective, leading to the formation of teams that perform better in a real environment. Being able to identify, before starting online training, those user characteristics that are predictors of a greater sense of presence can lead to the selection of trainees who would benefit most from the online simulated training. This is an observational study with a retrospective postsurvey of participants' user characteristics and degree of sense of presence. Twenty-nine members from 3 Air Force National Guard Medical Service expeditionary medical support teams participated in an online virtual environment training exercise and completed the Independent Television Commission-Sense of Presence Inventory survey, which measures sense of presence and user characteristics. Nonparametric statistics were applied to determine the statistical significance of user characteristics to sense of presence. Comparing user characteristics to the 4 scales of the Independent Television Commission-Sense of Presence Inventory using Kendall τ test gave the following results: the user characteristics "how often you play video games" (τ(26)=-0.458, Pvirtual environment experience such as dizziness, nausea, headache, and eyestrain. The user characteristic "knowledge of virtual reality" was significantly related to engagement (τ(26)=0.463, Pvirtual environments and experience with gaming environments report a higher sense of presence that indicates that they will likely benefit more from online virtual training. Future research studies could include a larger population of expeditionary medical support, and the results obtained could be used to create

Correlates and consequences of exposure to video game violence: hostile personality, empathy, and aggressive behavior.

Bartholow, Bruce D; Sestir, Marc A; Davis, Edward B

2005-11-01

Research has shown that exposure to violent video games causes increases in aggression, but the mechanisms of this effect have remained elusive. Also, potential differences in short-term and long-term exposure are not well understood. An initial correlational study shows that video game violence exposure (VVE) is positively correlated with self-reports of aggressive behavior and that this relation is robust to controlling for multiple aspects of personality. A lab experiment showed that individuals low in VVE behave more aggressively after playing a violent video game than after a nonviolent game but that those high in VVE display relatively high levels of aggression regardless of game content. Mediational analyses show that trait hostility, empathy, and hostile perceptions partially account for the VVE effect on aggression. These findings suggest that repeated exposure to video game violence increases aggressive behavior in part via changes in cognitive and personality factors associated with desensitization.

For extreme operating conditions in aerospace, nuclear power plants and medical applications, novel materials have become more competitive over traditional materials because of the unique characteristics. Extensive research programmes are being undertaken to develop high performance and knowledge-intensive new materials, since existing materials cannot meet the stringent technological requirements of advanced materials for emerging industries. The technologies of intermetallic compounds, nanostructural materials, advanced composites, and photonics materials are presented. In addition, medical biomaterial implants of high functional performance based on biocompatibility, resistance against corrosion and degradation, and for applications in hostile environment of human body are discussed. The opportunities for African researchers to collaborate in international research programmes to develop local raw materials into high performance materials are also highlighted. (au)

Job characteristics, burnout and negative workhome interference in a nursing environment

FE Koekemoer

2006-04-01

Full Text Available The objectives of this study were 1 to determine which job characteristics are associated with burnout and 2 to determine the mediating role of negative work-home interference (WHI in the relationship between job characteristics and burnout within a nursing environment. Random samples (n = 300 were taken of nurses working in the Johannesburg, Klerksdorp, Krugersdorp, Pretoria and Potchefstroom areas. The results of the regression analyses indicated that the main job characteristics that predict exhaustion were pressure and a lack of autonomy, role clarity, colleague support and financial support. A lack of role clarity, colleague support and financial support were the main job characteristics that predict mental distance. Negative WHI played a partially mediating role in the relationship between job characteristics and burnout.

Characteristics of a productive research environment: literature review.

Science.gov (United States)

Bland, C J; Ruffin, M T

1992-06-01

What environmental factors stimulate and maintain research productivity? To answer this question, the authors conducted an extensive review of articles and books on research productivity published from the mid-1960s through 1990. This review revealed that a consistent set of 12 characteristics was found in research-conducive environments: (1) clear goals that serve a coordinating function, (2) research emphasis, (3) distinctive culture, (4) positive group climate, (5) assertive participative governance, (6) decentralized organization, (7) frequent communication, (8) accessible resources, particularly human, (9) sufficient size, age, and diversity of the research group, (10) appropriate rewards, (11) concentration on recruitment and selection, and (12) leadership with research expertise and skill in both initiating appropriate organizational structure and using participatory management practices. Some of these characteristics are not surprising, although some findings were unexpected, such as that participative governance correlated consistently with research productivity. The differential impact of each of these 12 characteristics is unclear. It is clear, however, that the leader has a disproportionate impact through his or her influence on all of the other characteristics. Yet, an overarching feature of these characteristics is their interdependency. These factors do not operate in research groups as isolated characteristics. Rather, they are like fine threads of a whole fabric: individual, yet when interwoven, providing a strong, supportive, and stimulating backdrop for the researcher. The authors conclude that while at a distance the productive research enterprise looks like a highly robust entity, upon closer inspection it is revealed to be a delicate structure highly dependent on the existence and effective working of numerous individual, organizational, and leadership characteristics.

Interpersonal discrimination and depressive symptomatology: examination of several personality-related characteristics as potential confounders in a racial/ethnic heterogeneous adult sample

Science.gov (United States)

2013-01-01

Background Research suggests that reports of interpersonal discrimination result in poor mental health. Because personality characteristics may either confound or mediate the link between these reports and mental health, there is a need to disentangle its role in order to better understand the nature of discrimination-mental health association. We examined whether hostility, anger repression and expression, pessimism, optimism, and self-esteem served as confounders in the association between perceived interpersonal discrimination and CESD-based depressive symptoms in a race/ethnic heterogeneous probability-based sample of community-dwelling adults. Methods We employed a series of ordinary least squares regression analyses to examine the potential confounding effect of hostility, anger repression and expression, pessimism, optimism, and self-esteem between interpersonal discrimination and depressive symptoms. Results Hostility, anger repression, pessimism and self-esteem were significant as possible confounders of the relationship between interpersonal discrimination and depressive symptoms, together accounting for approximately 38% of the total association (beta: 0.1892, p interpersonal discrimination remained a positive predictor of depressive symptoms (beta: 0.1176, p personality characteristics in the association between reports of interpersonal discrimination and mental health, our results suggest that personality-related characteristics may serve as potential confounders. Nevertheless, our results also suggest that, net of these characteristics, reports of interpersonal discrimination are associated with poor mental health. PMID:24256578

Diagnostics in the hostile environments of a prototype fusion reactor

International Nuclear Information System (INIS)

Osher, J.E.

1982-01-01

Various facets of a thermonuclear type plasma that will likely require special considerations or hardening of applied diagnostic instrumentation are reviewed. The discussion will include both on-line diagnostic instrumentation requirements for satisfactory operation and considerations to reduce integrated radiation damage sufficiently for a reasonable diagnostic lifetime. Several new diagnostics aimed specifically at measurements of the plasma characteristics most appropriate to a thermonculear reactor type plasma are discussed. This will include instrumentation needed to make quantitative energy flow measurements during long term operation with the expected high input power sources, and locally very high wall power loadings. The second part of this lecture will broaden diagnostics to include materials damage measurements needed for engineering design studies. This will include needed diagnostic instrumentation to assess first wall damage, sputtering erosion at walls (and high power beam dumps), and radiation damage to components such as insulators

 The human body is a hostile environment for Aspergillus species, which originally live outside the human body. There are lots of elimination mechanisms against Aspergillus inhaled into the human body, such as high body temperature, soluble lung components, mucociliary clearance mechanism, or responses of phagocytes. Aspergillus fumigatus, which is the primary causative agent of human infections among the human pathogenic species of Aspergillus, defend itself from the hostile human body environment by various mechanisms, such as thermotolerance, mycotoxin production, and characteristic morphological features. Here we review mechanisms of defense in Aspergillus against elimination from the human body.

Full Text Available The purpose of the research, carried out in a sample of Slovene students, was to determine how subjects with migraine differ from subjects with migrainous disorder, subjects with non-migrainous headaches and subjects without recurrent headaches. The existence of migraine was assessed by UCSD migraine questionnaire, aggressiveness by Buss-Durkee hostility inventory and characteristics of object-relations by Bell object relations and reality testing inventory - form O. Subjects with migraine express significantly more negativism, indirect aggressiveness, irritability, hostility, suspicion and feelings of guilt than subject without recurrent headaches, while there are no differences in physical and verbal aggressiveness. There are less significant differences among subjects with different types of headache (migraine, migrainous disorder, non-migrainous headaches. Subjects with migraine and subjects without recurrent headaches differ significantly in characteristics of object-relations, subjects with migraine having more disturbed object-relations. Subject with different types of headaches do not differ in characteristics of object-relations. It is concluded that subjects with migraine have a raised level of aggressiveness, especially of indirect forms, which can indicate non-neutralized aggressiveness, and their object-relations are more disturbed.

Commercial fiber optics cables, both bundled and single-fiber, were evaluated for application in an in-line photometer being developed for monitoring uranium and plutonium concentrations in high radiation environments in nuclear fuel reprocessing plants. The relative attenuation of the optical signals due to both the radiation damage and to the couplings between lengths of optical cable was determined for specimen cables. An ultraviolet-enhanced fiber bundle demonstrated good radiation resistance to a total dose of 10 8 rads, which is the dose estimated to be received during a 1-y lifetime of the in-cell portion of the photometer. The photometer was designed to use a single-fiber optical cable with adequate radiation shielding

The language of racism. Textual testimonies of Jewish-Arab hostility in the Israeli Academia

Directory of Open Access Journals (Sweden)

Tamar Heger

2015-02-01

Full Text Available The persistent Jewish Arab conflict is present in every aspect of life in Israeli society and its echoes penetrate the everyday reality of higher educational institutions. Feelings of mutual hostility among Arab and Jewish students, faculty and administration are common experiences on Israeli campuses. This article analyzes two textual expressions of this mutual resentment which were circulated in 2011 in Tel Hai College, Israel. One of the texts was produced by Muslim Arab student association and the other by a Zionist Jewish organization. Both groups are present on every campus in Israel. Despite the significant difference of the political location occupied by each organization in the Israeli power structure, we argue that these texts share similar attitudes to the conflict and parallel operational strategies. The paper demonstrates the attempts by these texts to encourage the mutual hostility between Jews and Arabs by employing racist and violent discourse. The article tries to explain the silence of the college administration and faculty in the face of these racist acts, subsequently outlining a vision of a responsible academia which will banish any acts of racism.

A controlled study of Hostile-Helpless states of mind among borderline and dysthymic women

LYONS-RUTH, KARLEN; MELNICK, SHARON; PATRICK, MATTHEW; HOBSON, R. PETER

2008-01-01

The aim of this study was to determine whether women with borderline personality disorder (BPD) are more likely than those with dysthymia to manifest contradictory Hostile-Helpless (HH) states of mind. A reliable rater blind to diagnosis evaluated features of such mental representations in transcripts of Adult Attachment Interviews from 12 women with BPD and 11 women with dysthymia of similar socioeconomic status (SES), all awaiting psychotherapy. In keeping with three hierarchical (non-independent) a priori predictions regarding the mental representations of women with BPD, the results were that (a) all those with BPD, compared with half the group with dysthymia, displayed HH states of mind; (b) those with BPD manifested a significantly higher frequency of globally devaluing representations; and (c) they exhibited a strong trend toward identifying with the devalued hostile caregiver (58% BPD vs. 18% dysthymic). In addition, significantly more BPD than dysthymic patients made reference to controlling behavior towards attachment figures in childhood. These findings offer fresh insights into the nature of BPD and extend previous evidence concerning affected individuals’ patterns of thinking and feeling about childhood attachment figures.

In addition to the type of family, the authors consider the educational tactics of mothers. The combined effects of the type of family and educational tactics on psychological characteristics of the adolescent were investigated. Adolescence was chosen as a period, when on the one hand, a relatively stable personality structure is developed, and on the other hand, the importance of the immediate social environment is extremely high. For our study we selected the psychological characteristics, to the utmost revealing the reaction of children to their parents' divorce: the level of subjective control (degree of responsibility for their own lives, and the sovereignty of the psychological space (clearnesse of psychological boundaries. It is shown that the largest influence on the psychological characteristics of adolescents, regardless of the type of family, is rendered by hostility in maternal education. The dependence of psychological characteristics of maternal directiveness occurs only at high values ​​of such educational tactics that highlights the consistency of the obtained results with the classical

Although the introduction of computerized working environment to the nuclear facilities, the study on the human factors impacts of computers and automation has not been enough like the other industries. It is necessary to prepare the way to cope with the negative aspects in spite of many positive aspects of computerization in nuclear. This study is an empirical study including the survey of the human factor concerning, especially to the cognitive response of operators' and the experiments on the error proneness. At first, we survey the design and its changes of operator interface and interaction in nuclear power plants, and conclude five human factor issues. We discuss situation awareness issues as one of the major human factor concerning, and the assessment method. Secondly, a questionnaire and interviews survey to the operator's response characteristics are performed for possible criterion measures tot he in-depth study on the cognitive characteristics. Finally, several experiments are conducted to test the error proneness. The issues and findings of this study could be utilized to any further study on the cognitive characteristic of operators to the computerized work environment

To examine the influence of neighborhood environment on childhood overweight and obesity in Shelby County Schools, Tennessee, and whether and to what extent that influence varies by age, gender, and the specific environment characteristics. 41,283 students were surveyed covering both individual-level covariates and several objective measures of neighborhood environment. Multilevel logistic regressions were used to examine the influence of neighborhood-level variables on overweight+obesity and obesity with adjustment of individual-level covariates. Further, a stratified analysis for each of the six groups by school level and gender. For both overweight+obesity and obesity, younger children were less sensitive to neighborhood characteristics than older children, and boys are less sensitive than girls. For girls in middle and high schools, the risk of overweight+obesity and obesity were positively associated with population density, and negatively associated with percent of poverty and percent of unhealthy food. Boys' risk of overweight+obesity and obesity were positively associated with distance to park. Neighborhood environment plays an important role in childhood overweight and obesity, and the effects vary by age, gender, and the specific neighborhood characteristic. Intervention programs tailored to specific groups may be more effective than ones targeted to children as a whole. Copyright © 2018 Elsevier Inc. All rights reserved.

Effective Engagement of Hostile Audiences on Climate Change

Science.gov (United States)

Denning, A.

2011-12-01

In 2010 and 2011, I gave invited presentations of mainstream climate science to large conferences dismissive of climate change organized by the HEartland Institute. In this presentation I review some of the common objections raised by such audiences and outline effective strategies to rebut them in public venues or the media. Respectful engagement on a human level is much more effective than appeals from authority, scientific consensus, or numerical models. Starting from a base of agreement on basic facts helps establish a basis of trust, which is then nurtured through personal anecdotes and humor. The basic science of climate change is presented in a non-confrontational way with frequent use of examples from everyday life to explain physical principles. Although a hard core of hostile individuals may not be swayed by such an approach, my experience was that this type of engagement can be very effective with ordinary people. I strongly encourage more climate scientists to work with public audiences and the media.

Online antisocial behavior, such as cyberbullying, harassment, and trolling, is a widespread problem that threatens free discussion and has negative physical and mental health consequences for victims and communities. While prior work has proposed automated methods to identify hostile comments in online discussions, these methods work retrospectively on comments that have already been posted, making it difficult to intervene before an interaction escalates. In this paper we instead consider t...

Purpose. The principal anatomic contraindication to endovascular aneurysm repair (EVR) is an unfavorable proximal aortic neck. With increasing experience, a greater proportion of patients with unfavorable neck anatomy are being offered EVR. This study aimed to evaluate outcomes in patients with challenging proximal aortic neck anatomy. Methods. Prospectively collected data from 147 consecutive patients who underwent EVR between December 1997 and April 2005 were supplemented with a retrospective review of medical records and radiological images. Unfavorable anatomic features were defined as neck diameter >28 mm, angulation >60 deg., circumferential thrombus >50%, and length 30 days) (p = 0.57), distal type I endoleak (p = 0.40), type III endoleak (p 0.51), secondary interventions (p = 1.0), aneurysm sac expansion (p = 0.44), or 30 day mortality (p = 0.70). The good neck group had a significantly increased incidence of type II endoleak (p = 0.023). By multivariate analysis, the incidence of intraoperative adjunctive procedures was significantly increased in the presence of severe angulation (p = 0.041, OR 3.08, 95% CI 1.05-9.04). Conclusion. Patients with severely hostile proximal aortic neck anatomy may be treated with EVR, although severely angulated necks require additional intraoperative procedures. Early outcomes are encouraging and suggest that indications for EVR may be expanded to include patients with hostile neck anatomy

Deep geological disposal is currently accepted as the most appropriate method for permanently removing spent nuclear fuel from the living sphere of humans. For implementation of deep geological disposal, we need to understand the geological changes that have taken place over the past 100,000 years, encompassing active faults, volcanic activity, elevation, ubsidence, which as yet have not been considered in assessing the site characteristics for general facilities, as well as to investigate and analyze the geological structures, fracture systems and seismic responses regarding deep geological environment about 500 meters or more underground. In regions with high seismic activity, such as Japan, the Western United States and Taiwan, borehole seismometers installed deep underground are used to monitor seismic activity during the course of seismic wave propagation at various depths and to study the stress changes due to earthquakes and analyze the connection to fault movements. Korea Hydro and Nuclear Power Co., Ltd. (KHNP) have installed the deep borehole earthquake observatory at depths of about 300 to 600 meters in order to study the seismic response characteristics in deep geological environment on June, 2014 in Andong area. This paper will show the status of deep borehole earthquake observatory and the results of background noise response characteristics of these deep borehole seismic data as a basic data analysis. We present here the status of deep borehole seismometer installation by KHNP. In order to basic data analysis for the borehole seismic observation data, this study shows the results of the orientation of seismometer and background noise characteristics by using a probability density function. Together with the ground motion data recorded by the borehole seismometers can be utilized as basic data for seismic response characteristics studies with regard to spent nuclear fuel disposal depth and as the input data for seismic hazard assessment that

Hostile Attribution Bias Mediates the Relationship Between Structural Variations in the Left Middle Frontal Gyrus and Trait Angry Rumination

Full Text Available Angry rumination is a common mental phenomenon which may lead to negative social behaviors such as aggression. Although numerous neuroimaging studies have focused on brain area activation during angry rumination, to our knowledge no study has examined the neuroanatomical and cognitive mechanisms of this process. In this study, we conducted a voxel-based morphometry analysis, using a region of interest analysis to identify the structural and cognitive mechanisms underlying individual differences in trait angry rumination (as measured by the Angry Rumination Scale in a sample of 82 undergraduate students. We found that angry rumination was positively correlated with gray matter density in the left middle frontal gyrus (left-MFG, which is implicated in inhibition control, working memory, and emotional regulation. The mediation analysis further revealed that hostile attribution bias (as measured by the Social Information Processing–Attribution Bias Questionnaire acted as a cognitive mechanism underlying the positive association between the left-MFG gray matter density and trait angry rumination. These findings suggest that hostile attribution bias may contribute to trait angry rumination, while the left-MFG may play an important role in the development of hostile attribution bias and trait angry rumination. The study reveals the brain mechanisms of trait angry rumination and plays a role in revealing the cognitive mechanisms of the development of trait angry rumination.

Preventing alcohol-related harm in drinking environments is a growing international priority. Factors relating to the physical, social and staffing environments in bars can contribute to increased alcohol consumption and harm. Understanding the relationships between such factors and intoxication in European drinking environments is critical to developing appropriate interventions. We undertook a quantitative observational study in 60 bars in four European cities, in The Netherlands, Slovenia, Spain and the UK (n = 237 observational visits). Using a structured observational schedule, researchers recorded characteristics of the bar environment and rated customer intoxication levels. All physical bar characteristics showed associations with intoxication before interactions between them were controlled for. Hierarchical modelling found significant independent associations between intoxication and use of plastic glassware, promotion of non-alcoholic drinks (often energy drinks), permissive environments, poor washroom facilities, the presence of a dance floor, customer sexual activity/competitiveness and later observational time. Findings suggest that prevention efforts should focus on raising and enforcing managerial standards in bars. While harm reduction measures such as plastic glassware are often promoted for high risk bars, such measures are inadequate to address public health concerns and insufficient to demonstrate social responsibility.

Coelho, D.; Rizzo, F.; Kranzmann, A.; Monteiro, M.; Caminha, I.

2014-01-01

In the oxyfuel process, pure oxygen is burned in boilers with recycled gas producing a gas rich in CO_2, making it easer to capture the CO_2 in the end of the process. The present work investigates the high temperature corrosion characteristics of a model Fe-Cr-Co alloy in typical oxyfuel process environment. Samples were oxidized at 600°C during 1000 hours in single atmosphere condition, where the samples is exposed to the same gas in all faces, and in a dual atmosphere condition, where the sample is exposed to water vapor in one side and to oxyfuel gas in the other. Samples where characterized by SEM and EDX. Results showed that corrosion is higher in a dual atmosphere condition than in single condition. (author)

This study examined the interactive effects of injunctive norm exposure and hostile and benevolent sexist attitudes on men's sexually aggressive responses during a behavioral analogue paradigm in which they interacted online with a bogus female partner. Heterosexual adult men (n = 201), recruited from an online sample, read fictional information regarding other men's approval of misogynistic, paternalistic, or egalitarian treatment of women, or non-gender-relevant control information. Through a media preference survey, men then learned that their female partner disliked sexual content in films, after which they had an opportunity to send her up to 120 sec' worth of either a sexually explicit or nonsexual film clip. Validating the online sexual aggression paradigm, men with a 1-year history of sexual assault exhibited more sexually aggressive responding during the film selection paradigm. Moreover, exposure to injunctive norm information produced a boomerang effect, such that men high in hostile sexist attitudes showed an increase in sexual aggression when confronted with paternalism and gender equality norms. Conversely, exposure to paternalism and gender equality norms suppressed the otherwise protective function of high benevolent sexism in reducing men's sexually aggressive tendencies. The implications of these results for social norms interventions are discussed. © 2015 Wiley Periodicals, Inc.

To evaluate the outcomes and find the prognostic factors of endovascular abdominal aortic aneurysm repair (EVAR) in patients with hostile neck anatomy of the abdominal aorta. This study was performed on 100 patients with abdominal aneurysm who were treated with EVAR between March 2006 and December 2010. We divided the patients into two groups: good neck anatomy (GNA), and hostile neck anatomy (HNA) and then compared the primary success rate and the incidence rate of complications with EVAR between the two groups. Our aim was to determine the factors related to the complications of EVAR among HNA types. There were no significant differences of primary success rate and incidence rate of complications between the two groups. Among the types of HNA, the short neck angle [odd ratio (OR), 4.23; 95% confidence interval (CI), 1.21-18.70; p = 0.023] and large neck angle (OR, 2.58; 95% CI, 0.15-11.85; p = 0.031) showed a low primary success rate. The short neck angle (OR, 2.32; 95% CI, 1.18-12.29; p = 0.002) and large neck angle (OR, 4.67; 95% CI, 0.14-19.07; p = 0.032) showed a high incidence rate of early type 1 complication. In the case of the large neck angle (OR, 3.78; 95% CI, 0.96-20.80; p = 0.047), the large neck thrombus (OR, 2.23; 95% CI, 0.24-7.12; p = 0.035) and large neck calcification (OR, 2.50; 95% CI, 0.08-18.37; p 0.043) showed a high incidence rate of complications within a year. The results suggest that patients with hostile neck anatomy can be treated with EVAR successfully, although there was a higher incidence of complications in patients with a short neck length, severe neck angulation, circumferential thrombosis, and calcified proximal neck.

Diehl, Charlotte; Rees, Jonas; Bohner, Gerd

2012-01-01

We combine evolutionary and sociocultural accounts of sexual harassment, proposing that sexuality-related and hostility-related motives lead to different types of harassment. Specifically, men's short-term mating orientation (STMO) was hypothesized to predict only unwanted sexual attention but not gender harassment, whereas men's hostile sexism (HS) was hypothesized to predict both unwanted sexual attention and gender harassment. As part of an alleged computer-chat task, 100 male students could send sexualized personal remarks (representing unwanted sexual attention), sexist jokes (representing gender harassment), or nonharassing material to an attractive female target. Independently, participants' STMO, HS, and sexual harassment myth acceptance (SHMA) were assessed. Correlational and path analyses revealed that STMO specifically predicted unwanted sexual attention, whereas HS predicted both unwanted sexual attention and gender harassment. Furthermore, SHMA fully mediated the effect of HS on gender harassment, but did not mediate effects of STMO or HS on unwanted sexual attention. Results are discussed in relation to motivational explanations for sexual harassment and antiharassment interventions. © 2012 Wiley Periodicals, Inc.

A Least Squares Collocation Method for Accuracy Improvement of Mobile LiDAR Systems

Qingzhou Mao

2015-06-01

Full Text Available In environments that are hostile to Global Navigation Satellites Systems (GNSS, the precision achieved by a mobile light detection and ranging (LiDAR system (MLS can deteriorate into the sub-meter or even the meter range due to errors in the positioning and orientation system (POS. This paper proposes a novel least squares collocation (LSC-based method to improve the accuracy of the MLS in these hostile environments. Through a thorough consideration of the characteristics of POS errors, the proposed LSC-based method effectively corrects these errors using LiDAR control points, thereby improving the accuracy of the MLS. This method is also applied to the calibration of misalignment between the laser scanner and the POS. Several datasets from different scenarios have been adopted in order to evaluate the effectiveness of the proposed method. The results from experiments indicate that this method would represent a significant improvement in terms of the accuracy of the MLS in environments that are essentially hostile to GNSS and is also effective regarding the calibration of misalignment.

Cognitive theories of aggression propose that biased information processing is causally related to aggression. To test these ideas, the current study investigated the effects of a novel cognitive bias modification paradigm (CBM-I) designed to target interpretations associated with aggressive behavior. Participants aged 18-33 years old were randomly assigned to either a single session of positive training (n = 40) aimed at increasing prosocial interpretations or negative training (n = 40) aimed at increasing hostile interpretations. The results revealed that the positive training resulted in an increase in prosocial interpretations while the negative training seemed to have no effect on interpretations. Importantly, in the positive condition, a positive change in interpretations was related to lower anger and verbal aggression scores after the training. In this condition, participants also reported an increase in happiness. In the negative training no such effects were found. However, the better participants performed on the negative training, the more their interpretations were changed in a negative direction and the more aggression they showed on the behavioral aggression task. Participants were healthy university students. Therefore, results should be confirmed within a clinical population. These findings provide support for the idea that this novel CBM-I paradigm can be used to modify interpretations, and suggests that these interpretations are related to mood and aggressive behavior.

Full Text Available The paper presents the results of a study of the psychological characteristics of boys and girls from complete and incomplete families. In addition to the type of family, the authors consider the educational tactics of mothers. The combined effects of the type of family and educational tactics on psychological characteristics of the adolescent were investigated. Adolescence was chosen as a period, when on the one hand, a relatively stable personality structure is developed, and on the other hand, the importance of the immediate social environment is extremely high. For our study we selected the psychological characteristics, to the utmost revealing the reaction of children to their parents' divorce: the level of subjective control (degree of responsibility for their own lives, and the sovereignty of the psychological space (clearnesse of psychological boundaries. It is shown that the largest influence on the psychological characteristics of adolescents, regardless of the type of family, is rendered by hostility in maternal education. The dependence of psychological characteristics of maternal directiveness occurs only at high values of such educational tactics that highlights the consistency of the obtained results with the classical studies of single-parent families.DOI: http://dx.doi.org/10.12731/2218-7405-2013-3-6

Environmental characteristics within preschools that influence children's motor competence are largely unknown. The purpose of the present study was to examine the contribution of various preschool environmental characteristics to children's locomotor, object control, and total gross motor scores. Cross-sectional, observational study of 3-5 year-old children (n=229) from 22 preschools in South Carolina. The Children's Activity and Movement in Preschool Study (CHAMPS) Motor Skills Protocol assessed MC. Preschool directors provided information regarding policies and practices. The research team measured playgrounds and classrooms, and the Early Childhood Environment Rating Scale-Revised assessed preschool quality. Time spent in open space and electronic media use were also assessed using direct observation. The aforementioned variables predicted children's object control, locomotor, and total gross motor scores. Classroom size/child ratio, teacher education, playground size, electronic media use, and trips to outside organizations emerged as significant predictors of locomotor score and total motor score. The object control model was non-significant. Preschools may be able to promote motor competence by allowing children more time in open spaces, structured activity experiences, and by expanding existing outdoor playground space whenever possible.

Interpersonal responsibility is an indigenous Chinese personality construct, which is regarded to have positive social functions. Two studies were designed to explore the relationship among interpersonal responsibility, proposal allocation ratio, and responders’ hostile decisions in an ultimatum game. Study 1 was a scenario study using a hypothetical ultimatum game with a valid sample of 551 high school students. Study 2 was an experimental study which recruited 54 undergraduate students to play the incentivized ultimatum game online. The results of the two studies showed a significantly negative correlation between interpersonal responsibility and responders’ rejection responses only when the proposal allocation ratio was 3:7. In addition, in Study 2, interpersonal responsibility had negative effects on responders’ rejection responses under the offer of 3:7, even after controlling for the Big Five personality traits. Taken together, proposal allocation ratio might moderate the effects of interpersonal responsibility on hostile decision-making in the ultimatum game. The social function of interpersonal responsibility might be beyond the Big Five. PMID:29184518

Young people have a particular attitude on the questions about environment and energy, and also about technology. Several inquiries show that young people are more aware of environmental questions than their elders. Their anxiety is bigger against pollution than the average of French people and it seems that they are more attentive to dangers for the planet: it is the sign of a broader opening on the world. Young people are ready to adhere to a group or association for environment and have sympathy for ecologists; they have hostility against nuclear energy. Age and education level have to be specified to complicate the question. This contribution gives some elements about the opinion of young people between 15-25 years old on environment, technology and nuclear energy in France. (N.C.)

Longer you play, the more hostile you feel: examination of first person shooter video games and aggression during video game play.

This study investigated the effects of video game play on aggression. Using the General Aggression Model, as applied to video games by Anderson and Bushman, [2002] this study measured physiological arousal, state hostility, and how aggressively participants would respond to three hypothetical scenarios. In addition, this study measured each of these variables multiple times to gauge how aggression would change with increased video game play. Results showed a significant increase from baseline in hostility and aggression (based on two of the three story stems), which is consistent with the General Aggression Model. This study adds to the existing literature on video games and aggression by showing that increased play of a violent first person shooter video game can significantly increase aggression from baseline. 2007 Wiley-Liss, Inc.

This study examined associations between blood pressure (BP) and dispositional variables pertaining to anger and hostility. Black and White 25- to 44-year old male and female normotensives and unmedicated mild to moderate hypertensives completed four reliable self-report scales--the Cook-Medley Hostility (Ho) Scale, the Trait Anger subscale of the State-Trait Anger Scale (STAS-T), and the Cognitive Anger and Somatic Anger subscales of the Cognitive-Somatic Anger Scale--plus the Framingham Anger Scale and the Harburg Anger Scale. They also engaged in three laboratory tasks--Type A Structured Interview (SI), a video game, and a cold pressor task--that elicit cardiovascular reactivity. Ambulatory BP readings at home and at work were also obtained from most subjects. Blacks had significantly higher Ho and lower STAS-T scores than did Whites. Women reported higher levels of somatic anger than did men. White women showed significant positive correlations between STAS-T and systolic BP (SBP) and diastolic BP (DBP) both at rest in the laboratory and during the SI. Black women revealed significant positive relationships between STAS-T and SBP and DBP at rest in the laboratory and at work as well as with DBP during the cold pressor test. For Black men, cognitive anger and DBP at rest were positively related. In contrast, White men revealed significant negative correlations between Ho scores and SBP at rest and during the video game; these men also showed significant negative relationships between somatic anger and SBP and DBP reactivity during the cold pressor test. Women, but not men, showed significant positive relationships between all four anger measures and ambulatory BP at work. Whereas main effects relating anger and cardiovascular measures were not apparent as a function of race, Blacks demonstrated significantly greater SBP and DBP reactivity than Whites during the cold pressor test, with the converse occurring during the SI. Men demonstrated significantly greater

Eleven JR, 18 private and 10 subway lines were surveyed, which cover 97% of whole train lines in Tokyo district in terms of annual number of passengers. The characteristics of environmental radiation field on train lines were discussed. The mean absorbed dose rate in air due to γ-rays on the subway lines was higher than those on the JR and private lines. It is due to the difference in the radioactivity concentration and the distribution of surrounding materials as the γ-ray sources. On the other hand, the mean dose rate due to cosmic-rays on the subway lines was lower than those on the JR and private lines. It is due to the shielding effect of the upper materials such as soil or building materials of tunnels. The mean dose rates for the JR, private and subway lines were calculated using these obtained data. Though the ratio of mean dose rate of γ-rays to that of cosmic-rays for the subway lines was different from those for the JR and private lines, the sum of γ- and cosmic-ray dose rates for the JR, private and subway lines were comparable, 40∼50 nGy/h for any of them. These data will be useful for a precise and realistic evaluation of collective dose, considering the life style of the public and the variation characteristics of environmental radiation. (author)

Although the introduction of computerized working environment to the nuclear facilities, the study on the human factors impacts of computers and automation has not been enough like the other industries. It is necessary to prepare the way to cope with the negative aspects in spite of many positive aspects of computerization in nuclear. This study is an empirical study including the survey of the human factor concerning, especially to the cognitive response of operators' and the experiments on the error proneness. At first, we survey the design and its changes of operator interface and interaction in nuclear power plants, and conclude five human factor issues. We discuss situation awareness issues as one of the major human factor concerning, and the assessment method. Secondly, a questionnaire and interviews survey to the operator's response characteristics are performed for possible criterion measures to the in-depth study on the cognitive characteristics. Finally, several experiments are conducted to test the error proneness. The issues and findings of this study could be utilized to any further study on the cognitive characteristic of operators to the computerized work environment.

Pornari, Chrisa D; Wood, Jane

2010-01-01

This study investigated the relationship between cognitive mechanisms, applied by people to rationalize and justify harmful acts, and engagement in traditional peer and cyber aggression among school children. We examined the contribution of moral disengagement (MD), hostile attribution bias, and outcome expectancies, and we further explored the individual contribution of each MD mechanism. Our aim was to identify shared and unique cognitive factors of the two forms of aggression. Three hundred and thirty-nine secondary school children completed self-report measures that assessed MD, hostile attribution bias, outcome expectancies, and their roles and involvement in traditional and cyber aggression. We found that the MD total score positively related to both forms of peer-directed aggression. Furthermore, traditional peer aggression positively related to children's moral justification, euphemistic language, displacement of responsibility and outcome expectancies, and negatively associated with hostile attribution bias. Moral justification also related positively to cyber aggression. Cyber aggression and cyber victimization were associated with high levels of traditional peer aggression and victimization, respectively. The results suggest that MD is a common feature of both traditional and cyber peer aggression, but it seems that traditional forms of aggression demand a higher level of rationalization or justification. Moreover, the data suggest that the expectation of positive outcomes from harmful behavior facilitates engagement in traditional peer aggression. The differential contribution of specific cognitive mechanisms indicates the need for future research to elaborate on the current findings, in order to advance theory and inform existing and future school interventions tackling aggression and bullying.

Overall, Nickola C; Fletcher, Garth J O; Simpson, Jeffry A; Fillo, Jennifer

2015-05-01

In the current research, we tested the extent to which attachment insecurity produces inaccurate and biased perceptions of intimate partners' emotions and whether more negative perceptions of partners' emotions elicit the damaging behavior often associated with attachment insecurity. Perceptions of partners' emotions as well as partners' actual emotions were assessed multiple times in couples' conflict discussions (Study 1) and daily during a 3-week period in 2 independent samples (Study 2). Using partners' reports of their own emotional experiences as the accuracy benchmark, we simultaneously tested whether attachment insecurity was associated with the degree to which individuals (a) accurately detected shifts in their partners' negative emotions (tracking accuracy), and (b) perceived their partners were feeling more negative relationship-related emotions than they actually experienced (directional bias). Highly avoidant perceivers were equally accurate at tracking their partners' changing emotions compared to less avoidant individuals (tracking accuracy), but they overestimated the intensity of their partners' negative emotions to a greater extent than less avoidant individuals (directional bias). In addition, more negative perceptions of partners' emotions triggered more hostile and defensive behavior in highly avoidant perceivers both during conflict discussions (Study 1) and in daily life (Study 2). In contrast, attachment anxiety was not associated with tracking accuracy, directional bias, or hostile reactions to perceptions of their partners' negative emotions. These findings demonstrate the importance of assessing biased perceptions in actual relationship interactions and reveal that biased perceptions play an important role in activating the defenses of avoidantly attached people.

Study to optimize a disposal tunnel layout taking into account heterogeneous characteristics of the geological environment

International Nuclear Information System (INIS)

Suyama, Yasuhiro; Toida, Masaru; Yanagizawa, Koichi

2007-01-01

The geological environment has spatially heterogeneous characteristics with varied host rock types, fractures and so on. In this case the generic disposal tunnel layout, which has been designed by JNC, is not the most suitable for HLW disposal in Japan. The existence of spatially heterogeneous characteristics means that in the repository region there exist sub-regions that are more favorable from the perspective of long-term safety and ones that are less favorable. In order that the spatially heterogeneous environment itself may be utilized most effectively as an NBS, an alternative design of disposal tunnel layout is required. Focusing on the geological environment with spatially heterogeneous characteristics, the authors have developed an alternative design of disposal tunnel layout. The alternative design adopts an optimization approach using a 'variable disposal tunnel layout'. The optimization approach minimizes the number of locations where major water conducting fractures are intersected, and maximizes the number of emplacement locations for waste packages. This paper will outline the variable disposal tunnel layout and its applicability. (author)

For many years, some urban architecture has aimed to exclude unwanted groups of people from some locations. This type of architecture is called "defensive" or "hostile" architecture and includes benches that cannot be slept on, spikes in the ground that cannot be stood on, and pieces of metal that hinder one's ability to skateboard. These defensive measures have sparked public outrage, with many thinking such measures lead to suffering, are disrespectful, and violate people's rights. In this ...

Resentment of paternalism as system change sentiment: hostile sexism toward men and actual behavior in the 2008 U.S. presidential election.

Science.gov (United States)

Tate, Charlotte Chuck

2014-01-01

Taking inspiration from Glick and colleagues (2004), this study tested the idea that resentment of paternalism (which is part of the hostile sexism toward men construct) might approximate desire for system change by correlating this variable with actual behavior associated with system change in a single culture. Specifically, voting behavior in the 2008 U.S. presidential election was predicted from political party affiliation, measures of hostile and benevolent sexism toward both women and men, and egalitarian racial attitudes using a U.S. college student sample. Results indicated that the only significant predictors of voting behavior were political party affiliation, resentment of paternalism, and egalitarian racial attitudes. Higher levels of resentment of paternalism were in fact associated with voting for the ticket that represented system change-holding the other predictors constant.

The purpose of this research was to begin to characterize and compare the school and home language environments of 10 preschool-aged children with Autism Spectrum Disorders (ASD). Naturalistic language samples were collected from each child, utilizing Language ENvironment Analysis (LENA) digital voice recorder technology, at 3-month intervals over the course of one year. LENA software was used to identify 15-min segments of each sample that represented the highest number of adult words used during interactions with each child for all school and home language samples. Selected segments were transcribed and analyzed using Systematic Analysis of Language Transcripts (SALT). LENA data was utilized to evaluate quantitative characteristics of the school and home language environments and SALT data was utilized to evaluate quantitative and qualitative characteristics of language environment. Results revealed many similarities in home and school language environments including the degree of semantic richness, and complexity of adult language, types of utterances, and pragmatic functions of utterances used by adults during interactions with child participants. Study implications and recommendations for future research are discussed. The reader will be able to, (1) describe how two language sampling technologies can be utilized together to collect and analyze language samples, (2) describe characteristics of the school and home language environments of young children with ASD, and (3) identify environmental factors that may lead to more positive expressive language outcomes of young children with ASD.

Full Text Available Michael R Woodford1, Amy R Krentzman2, Maurice N Gattis31School of Social Work, University of Michigan, Ann Arbor, MI, USA; 2Department of Psychiatry, University of Michigan, Ann Arbor, MI, USA; 3School of Social Work, University of Wisconsin-Madison, Madison, WI, USAPurpose: Research suggests that discrimination contributes to increased substance use among sexual minorities. Subtle discrimination and witnessing mistreatment, however, have received little attention. Using minority stress theory as a conceptual framework the authors examined the intersection of sexual orientation, experiencing and witnessing incivility and hostility, and students' alcohol and drug use. The authors hypothesized that experiencing/witnessing incivility/hostility would mediate the relationship between sexual minority status and drinking and drug use, as well as problematic use of these substances.Methods: Data were taken from a campus climate survey (n = 2497; age mean [M] = 23.19 years; 61% female; 17% sexual minorities. Controlling for demographics, logistic regressions depicted specifications for each path of the mediation analysis and bootstrapping was used to assess the significance of each sexual minority-mistreatment-drinking/drug use path.Results: Experiencing incivility mediated the relationship between sexual minority status and problematic drinking. Sexual minority college students were more likely to personally experience incivility (adjusted odds ratio [AOR] = 1.87; 95% confidence interval [CI] = 1.51–2.33, which was associated with greater odds of problematic drinking (AOR = 1.64; 95% CI = 1.35–2.00. The mediation path was significant at P < 0.001. Further, witnessing hostility mediated the relationship between sexual minority status and problematic drinking. Sexual minority college students were more likely to witness hostility (AOR = 1.87, 95% CI = 1.48–2.36, which was associated with greater odds of problematic drinking (AOR = 1.53; 95% CI = 1

People are strongly motivated to feel accepted by others. Yet when faced with acute peer rejection they often aggress against the very peers they desire acceptance from, which may lead to further rejection. The present experiment tests three potential mediators of aggressive responses to acute peer rejection in the critical developmental stage of early adolescence. Participants (N=185, M(age)=11.5 years) completed personal profiles that were allegedly evaluated online by peers. After receiving negative or neutral peer feedback, participants could aggress against the same peers who had evaluated them. Rejected participants attributed more hostile intent to the peers, were angrier, showed a greater reduction in state self-esteem, and were more aggressive. Mediational analyses showed that hostile intent attributions mediated the acute peer rejection-aggression relationship, whereas increases in anger and decreases in state self-esteem did not. Thus, acute peer rejection evokes hostile intent attributions that, in turn, lead to aggressive reactions. © 2011 by the Society for Personality and Social Psychology, Inc

Stressful childhood environments arising from deficient nurturing attitudes are hypothesized to contribute to later stress vulnerability. We examined whether deficient nurturing attitudes predict adulthood work stress. Participants were 443 women and 380 men from the prospective Cardiovascular Risk in Young Finns Study. Work stress was assessed as job strain and effort-reward imbalance in 2001 when the participants were from 24 to 39 years old. Deficient maternal nurturance (intolerance and low emotional warmth) was assessed based on mothers' reports when the participants were at the age of 3-18 years and again at the age of 6-21 years. Linear regressions showed that deficient emotional warmth in childhood predicted lower adulthood job control and higher job strain. These associations were not explained by age, gender, socioeconomic circumstances, maternal mental problems or participant hostility, and depressive symptoms. Deficient nurturing attitudes in childhood might affect sensitivity to work stress and selection into stressful work conditions in adulthood. More attention should be paid to pre-employment factors in work stress research.

An investigation into the impact of cryogenic environment on mechanical stresses in FRP composites

Science.gov (United States)

Fifo, O.; Basu, B.

2015-07-01

Fibre reinforced polymer (FRP) composites are fast becoming a highly utilised engineering material for high performance applications due to their light weight and high strength. Carbon fibre and other high strength fibres are commonly used in design of aerospace structures, wind turbine blades, etc. and potentially for propellant tanks of launch vehicles. For the aforementioned fields of application, stability of the material is essential over a wide range of temperature particularly for structures in hostile environments. Many studies have been conducted, experimentally, over the last decade to investigate the mechanical behaviour of FRP materials at varying subzero temperature. Likewise, tests on aging and cycling effect (room to low temperature) on the mechanical response of FRP have been reported. However, a relatively lesser focused area has been the mechanical behaviour of FRP composites under cryogenic environment. This article reports a finite element method of investigating the changes in the mechanical characteristics of an FRP material when temperature based analysis falls below zero. The simulated tests are carried out using a finite element package with close material properties used in the cited literatures. Tensile test was conducted and the results indicate that the mechanical responses agree with those reported in the literature sited.

The home environment is likely to influence children's diet and activity patterns and ultimately, their weight trajectories. Identifying family characteristics associated with a more 'obesogenic' home can provide insight into the determinants, and has implications for targeting and tailoring strategies to promote healthier lifestyles. The present study examined maternal characteristics associated with a more obesogenic home environment in 1113 families with preschool children. Primary caregivers (99% mothers) from the Gemini cohort completed the Home Environment Interview (HEI) when their children were 4 years old. Maternal demographics and BMI were assessed in the Gemini baseline questionnaire when the children were on average 8 months old. Maternal eating style was assessed when the children were on average 2 years old, using the Dutch Eating Behaviour Questionnaire (DEBQ). Responses to the HEI were standardised and summed to create a composite score of the obesogenic quality of the home; this was categorised into tertiles. Multivariate ordinal logistic regression showed that mothers who were younger (adjusted OR; 95% CI = 0.96; 0.94-0.98), less educated (1.97; 1.40-2.77), and had lower incomes (1.89; 1.43-2.49) at baseline were more likely to live in an obesogenic home environment at 4 years, as were mothers who scored higher on the DEBQ External Eating scale (1.40; 1.16-1.70) at 2 years, and had a higher baseline BMI (1.05; 1.02-1.08). Using a novel, composite measure of the home environment, this study finds that families who are more socio-economically deprived, and where the mothers are themselves heavier and have a more food responsive eating style, tend to provide a home environment with the hallmarks of a higher risk of weight gain.

Full Text Available Sexual harassment has been widely studied in the workforce, but the factors that contribute to hostile educational environments for women have received less attention. The present study focuses on male dominance, gender harassment, gender threats, masculinity, and their influences on creating a hostile environment for women in academia. One hundred and forty-two male participants from a private university in the Southwestern United States self-reported their masculinity, completed a group task with a female confederate leader serving as a gender threat in half the conditions, and had their subsequent affect, perceptions of leadership effectiveness, and behavioral aggression measured. Men from male-dominated majors and men who had received a gender threat did not differ from men from gender-equivalent majors and men who had not received a gender threat on affect, perceptions of leadership effectiveness, or behavioral aggression (ps > 0.201, ηp2s ≤ 0.007. However, post-hoc analyses revealed that as masculinity increased among men from male-dominated majors under gender threat, they became significantly more behaviorally aggressive (b = 5.92, p = 0.003 and perceived their female leader as less effective (b = −0.83, p = 0.076. Implications and suggestions for future research are discussed.

Modern mining support, for the entire period of their use, is the important part of the mining complex, which includes all the devices in the excavation during his normal use. Therefore, during the design of the support, it is an important task to choose the shape and to select the dimensions of a support as well as its strength characteristics. According to the rules, the design process of a support must take into account, inter alia, the type and the dimensions of the expected means of transport, the number and size of pipelines, and the type of additional equipment used excavation area. The support design must ensure the functionality of the excavation process and job security, while maintaining the economic viability of the entire project. Among others it should ensure the selection of a support for specific natural conditions. It is also important to take into consideration the economic characteristics of the project. The article presents an algorithm of integrative approach and its formalized description in the form of integration the areas of different construction characteristics optimization of a V-type mining support.

The aim of this study was to evaluate the effect of ambient temperature on the physical and chemical characteristics of the longissimus dorsi muscle by comparing the quality of meat from pigs reared in a controlled and in an uncontrolled environment, the latter provided with a shallow pool. Twenty castrated male pigs of the Topigs line were randomly allotted to two treatments: a controlled environment, with constant temperature (22 °C) and relative humidity (70%); and an uncontrolled environment in a conventional shed for rearing pigs equipped with a shallow pool, where pigs were subject to climatic variations. Meat from pigs kept in the controlled environment showed a greater capacity to retain intracellular water, higher tenderness, and lower cholesterol levels than meat from pigs reared in the uncontrolled environment, but displayed higher lipid oxidation and a lower concentration of DHA. Treatments had no effect on color, pH, chemical composition, or fatty acid profile (except DHA concentration). Rearing pigs in sheds equipped with a shallow pool minimizes the effects of environmental heat on meat quality, allowing the production of high-quality meat in warm climate regions without expensive investments. Animals reared in an uncontrolled environment equipped with a shallow pool are able to produce meat with characteristics within the quality standards and with similar quality to that of meat from animals raised in controlled environment.

To assess turnover intention among experienced nurses and explore the effects of work environment, job characteristics and work engagement on turnover intention. The nursing shortage is an urgent concern in China. A high turnover rate of experienced nurses could have serious effects on the quality of care, costs and the efficiency of hospitals. It is crucial to explore the predictors of turnover intention and develop strategies tailored to experienced nurses. A descriptive, cross-sectional survey design. A total of 778 experienced nurses from seven hospitals was surveyed on their work engagement, job characteristics, work environment and turnover intention in March-May 2017. Structural equation modelling was used to test a theoretical model and the hypotheses. The results showed that 35.9% of experienced nurses had high-level turnover intention. The final model explained 50% of the variance in experienced nurses' turnover intention and demonstrated that: (1) work environment was positively associated with higher work engagement and lower turnover intention and work engagement partially mediated the relationship between work environment and turnover intention; and (2) job characteristics were positively related to higher work engagement and lower turnover intention and work engagement fully mediated the relationship between job characteristics and turnover intention. The study confirms the intrinsic and extrinsic motivators on work engagement posited by job demands-resources model. Theory-driven strategies to improve work environment, enhance job characteristics and promote wok engagement are needed to address the nursing shortage and high turnover intention among experienced nurses. © 2018 John Wiley & Sons Ltd.

Poison pills: A defensive measure against a hostile takeover or a demonstration of power of the target company

Directory of Open Access Journals (Sweden)

Jovanović-Zattila Milena

2014-01-01

Full Text Available The balance of power is particularly at stake in hostile takeovers, which makes the issue of establishing the balance of power one of the most controversial issues in the contemporary company law. In the circumstances of direct market competition and the need to have a dominant market position, companies are necessarily forced to constantly upgrade and advance their offensive and defensive methods, techniques and strategies. In order to prevent a hostile takeover, the target company may resort to an array of defence mechanisms, the most prominent of which are 'poison pills'. In spite of being perceived as the most powerful tool for obstructing hostile takeovers (and commonly designated as the 'Holy Grail' among the defensive mechanisms, there are many pros and cons underlying their application. One of the positive effects of using the poison pills is that the fear of takeovers makes the target company management more disciplined and efficient in business operations. The negative consequences are reflected in the relationship between the company board of directors and the shareholders. The target company management makes a unilateral decision on using a poison pill and this decision does not have to be approved by the shareholders in the General Meeting; however, this is highly inconsistent with the basic principles of corporate governance. The asymmetry of information, where the management (an agent has disproportionately more relevant information at its disposal than the shareholders (principals, generates a conflict between the management and the shareholders. In company law, this agency problem is generally known as the principal-agent problem, which is most prominent in a takeover. Poison pills are often associated with the discrimination of the target company shareholders, but not necessarily. The controversial nature of this defensive measure which can be applied by the target company has given rise to numerous debates on the need to

Radar operation in a hostile electromagnetic environment

Radar ISR does not always involve cooperative or even friendly targets. An adversary has numerous techniques available to him to counter the effectiveness of a radar ISR sensor. These generally fall under the banner of jamming, spoofing, or otherwise interfering with the EM signals required by the radar sensor. Consequently mitigation techniques are prudent to retain efficacy of the radar sensor. We discuss in general terms a number of mitigation techniques.

Experimentally studying the influence of social environments on mental health and behavior is challenging, as social context is difficult to standardize in laboratory settings. Virtual Reality (VR) enables studying social interaction in terms of interpersonal distance in a more ecologically valid manner. Regulation of interpersonal distance may be abnormal in patients with psychotic disorders and influenced by environmental stress, symptoms or distress. To investigate interpersonal distance in people with a psychotic disorder and at ultrahigh risk for psychosis (UHR) compared to siblings and controls in virtual social environments, and explore the relationship between clinical characteristics and interpersonal distance. Nineteen UHR patients, 52 patients with psychotic disorders, 40 siblings of patients with a psychotic disorder and 47 controls were exposed to virtual cafés. In five virtual café visits, participants were exposed to different levels of social stress, in terms of crowdedness, ethnicity and hostility. Measures on interpersonal distance, distress and state paranoia were obtained. Baseline measures included trait paranoia, social anxiety, depressive, positive and negative symptoms. Interpersonal distance increased when social stressors were present in the environment. No difference in interpersonal distance regulation was found between the groups. Social anxiety and distress were positively associated with interpersonal distance in the total sample. This VR paradigm indicates that interpersonal distance regulation in response to environmental social stressors is unaltered in people with psychosis or UHR. Environmental stress, social anxiety and distress trigger both people with and without psychosis to maintain larger interpersonal distances in social situations. Copyright © 2017 Elsevier B.V.

One dimensional nanowire field effect transistors (NW-FETs) are a promising platform for sensor applications. The transport characteristics of NW-FETs are strongly modified in liquid environment due to the charging of surface functional groups accompanied with protonation or deprotonation. In order to investigate the influence of surface charges and ionic concentrations on the transport characteristics of Schottky-barrier NW-FETs, we have combined the modified Poisson-Boltzmann theory with the Landauer-Büttiker transport formalism. For a typical device, the model is able to capture the reduction of the sensitivity of NW-FETs in ionic solutions due to the screening from counter ions as well as a local gating from surface functional groups. Our approach allows to model, to investigate, and to optimize realistic Schottky-barrier NW-FET devices in liquid environment.

Full Text Available The purpose of this research is to investigate whether there are differences in the level of computer literacy, the amount of implementation of ICT in teaching and learning-assessment processes and the attitudes of teachers from computerized schools in comparison to teachers in non-computerized schools. In addition, the research investigates the characteristics of Israeli school teachers in a 21st century computer-based learning environment. A quantitative research methodology was used. The research sample included 811 elementary school teachers from the Jewish sector of whom 402 teachers were from the computerized school sample and 409 were teachers from the non-computerized school sample. The research findings show that teachers from the computerized school sample are more familiar with ICT, tend to use ICT more and have a more positive attitude towards ICT than teachers in the non-computerized school sample. The main conclusion which can be drawn from this research is that positive attitudes of teachers towards ICT are not sufficient for the integration of technology to occur. Future emphasis on new teaching skills of collective Technological Pedagogical Content Knowledge is necessary to promote the implementation of optimal pedagogy in innovative environments.

Full Text Available This paper investigates the output characteristics of photovoltaic solar cells working in hostile working conditions. Examined cells, produced by different innovative procedures, are available in the market. The goal was to investigate stability of electric characteristics of solar cells, which are used today in photovoltaic solar modules for charging rechargeable batteries which, coupled with batteries, supply various electronic systems such as radio repeaters on mountains tops, airplanes, mobile communication stations and other remote facilities. Charging of rechargeable batteries requires up to 25 % higher voltage compared to nominal output voltage of the battery. This paper presents results of research of solar cells, which also apply to cases in which continuous power supply is required. [Projekat Ministarstva nauke Republike Srbije, br. III 171007

Effects of Weapons on Aggressive Thoughts, Angry Feelings, Hostile Appraisals, and Aggressive Behavior: A Meta-Analytic Review of the Weapons Effect Literature.

Benjamin, Arlin J; Kepes, Sven; Bushman, Brad J

2017-09-01

Guns are associated with aggression. A landmark 1967 study showed that simply seeing a gun can increase aggression-called the "weapons effect." This meta-analysis integrates the findings of weapons effect studies conducted from 1967 to 2017. It includes 162 effect-size estimates from 78 independent studies involving 7,668 participants. The theoretical framework used to explain the weapons effect was the General Aggression Model (GAM), which proposes three routes to aggression-cognitive, affective, and arousal. The GAM also proposes that hostile appraisals can facilitate aggression. As predicted by the GAM, the mere presence of weapons increased aggressive thoughts, hostile appraisals, and aggression, suggesting a cognitive route from weapons to aggression. Weapons did not significantly increase angry feelings. Only one study tested the effects of weapons on arousal. These findings also contribute to the debate about social priming by showing that incidental exposure to a stimulus (weapon) can affect subsequent related behavior (aggression).

To identify the effects of workplace bullying in the radiation therapy department on job performance and explore the environment and morale of individuals who work with a bully. A quantitative research study was designed to assess the prevalence and effects of bullying in the radiation therapy workplace. A total of 308 radiation therapists participated in the study for a return rate of 46%. Of those, 194 indicated that workplace bullying was present either in their current workplace or in a previous radiation therapy environment and that it negatively affected job performance and satisfaction. Findings of this study indicate a need for evaluation of the radiation therapy workplace, education on how to identify and prevent bullying behavior, and better communication among members of the radiation therapy environment. Participants indicated that working in a hostile environment led to forgetfulness, ineffective communication, and perceived discrepancies in promotion and treatment by management. Any bullying behavior contributes to an overall toxic work environment, which is unhealthy and unsafe for patients and therapists. Those who manage therapists should promote a culture of safety and embrace their staff's independence.

A lack of relationship between direct care staffing levels and quality of care, as found in prior studies, underscores the importance of considering the quality of the work environment instead of only considering staff ratios. Only a few studies, however, have combined direct care staffing with work environment characteristics when assessing the relationship with quality of care in nursing homes. To examine the relationship between direct care staffing levels, work environment characteristics and perceived quality of care in Dutch nursing homes. Cross-sectional, observational study in cooperation with the Dutch Prevalence Measurement of Care Problems. Twenty-four somatic and 31 psychogeriatric wards from 21 nursing homes in the Netherlands. Forty-one ward managers and 274 staff members (registered nurses or certified nurse assistants) from the 55 participating wards. Ward rosters were discussed with managers to obtain an insight into direct care staffing levels (i.e, total direct care staff hours per resident per day). Participating staff members completed a questionnaire on work environment characteristics (i.e., ward culture, team climate, communication and coordination, role model availability, and multidisciplinary collaboration) and they rated the quality of care in their ward. Data were analyzed using multilevel linear regression analyses (random intercept). Separate analyses were conducted for somatic and psychogeriatric wards. In general, staff members were satisfied with the quality of care in their wards. Staff members from psychogeriatric wards scored higher on the statement 'In the event that a family member had to be admitted to a nursing home now, I would recommend this ward'. A better team climate was related to better perceived quality of care in both ward types (p≤0.020). In somatic wards, there was a positive association between multidisciplinary collaboration and agreement by staff of ward recommendation for a family member (p=0.028). In

2017-12-01

Full Text Available The modernization of work relationships and the new demands of the market about the worker profile contributed for establishment of human relations from a utilitarian logic, which favors the competition and hostility, and allows the configuration of a scenario conducive to psychological violence situations at work, especially to moral harassment occurrence. Based on these premises, the paper analyzes the characteristics and reach of the moral harassment in the workplace to show that prevention through compliance programs is more effective to promote ergonomic ethics and, consequently, to mitigate moral harassment cases.

Effects of Gene × Attachment Interaction on Adolescents’ Emotion Regulation and Aggressive Hostile Behavior Towards their Mothers during a Computer Game

Zimmermann, Peter; Spangler, Gottfried

2016-01-01

Adolescence is a time of increased emotionality and major changes in emotion regulation often elicited in autonomy-relevant situations. Both genetic as well as social factors may lead to inter-individual differences in emotional processes in adolescence. We investigated whether both 5-HTTLPR and attachment security influence adolescents’ observed emotionality, emotional dysregulation, and their aggressive hostile autonomy while interacting with their mothers. Eighty-eight adolescents at age 12 were observed in interaction with their mothers during a standardized, emotion eliciting computer game task. They were genotyped for the 5-HTTLPR, a repeat polymorphism in the promoter region of the serotonin transporter gene. Concurrent attachment quality was assessed by the Late Childhood Attachment Interview (LCAI). Results revealed a significant gene × attachment effect showing that ss/sl carriers of 5-HTTLPR show increased emotional dysregulation and aggressive hostile autonomy towards their mothers. The results of the study suggest that secure attachment in adolescence moderates the genetically based higher tendency for emotional dysregulation and aggressive reactions to restrictions of autonomy during emotional social interactions with their mothers.

Subjective Evaluation of Media Content as a Moderator of Media Effects on European Identity: Mere Exposure and the Hostile Media Phenomenon

Directory of Open Access Journals (Sweden)

Waqas Ejaz

2017-05-01

Full Text Available This paper posits that the concept of European identity is an important indicator of the legitimacy of the European Union (EU. It further assumes that the exposure to EU related media content can influence the feeling of European identity. In order to verify this assumption, we combined the mere-exposure-theory and the hostile media phenomenon. We assume that these theoretical concepts could help to understand the influence of media on people’s levels of attachment to the EU. Regression analyses are performed on secondary data that were collected in a Eurobarometer survey in 2013. Our findings revealed that media exposure affected the respondents’ identification with Europe, as well as the modifications of this effect based on their assessments of EU media coverage. The results of the current study not only validate assumptions about the mere-exposure effects on identity but also confirm the theoretical assumption that perceived hostility reduces such effects, whereas exposure to information that is perceived as neutral promotes the effects of media exposure on the feeling of European identity.

Full Text Available The aim of the present study was to evaluate the possible effect of environmental factors on meiosis, meiotic index, pollenviability and in vitro germination of pollen from stock plants of the rootstocks Trifoliate, ‘Swingle’, ‘Troyer’, ‘Fepagro C13’, ‘FepagroC37’ and ‘Fepagro C41’ grown in a protected environment in comparison with stock plants grown in the field. The results showed thatvalues for the characteristics analyzed in 2008, 2009 and 2010 were always higher in the field than in the greenhouse conditions. Inthe field, the average of normal meiotic cells was 60.05%, 44.44% and 60.12%, respectively, and in the greenhouse, 52.75%, 30.95%and 52.82%, respectively. Mean pollen viability in the field was 90.28%, 56.23% and 74.74%, and, in the greenhouse, 64.25%, 41.41%and 66.71%, respectively. As temperature oscillations were higher in the greenhouse than in the field, we suggest that this negativelyaffects the reproductive characteristics analyzed.

Lateral hostilities among emergency and critical care nurses. Survey in five hospitals of Tuscany Region. Introduction. Lateral hostilities (LHs) are a kind of workplace violence. They are defined as varieties of cruel, rude, antagonistic interactions between people at the same hierarchical level. Nurses are affected by LH from 5.7% to 65%, leading to reduced work motivation, psycho-physical disorders, and in some cases, drop out of the nursing profession. Objective. To quantify the LHs among nurses in the emergency departments (ED) and intensive care units (ICU) in 5 hospitals of Tuscany (Italy). To show the impact on the quality of their psycho-physical and professional lives. Method. Exploratory-descriptive study, through closed-ended questionnaire. Results. 360/444 nurses (81%); 294 (81.6%) were victims of LHs during the past 12 months. Gossiping, complaints shared with others without discussing with the concerned person, and sarcastic comments were the most reported LHs. LHs occur more in EDs than ICUs (respectively 90% and 77%; p=0.0038). No statistically significant differences were observed for gender, age, or years of experience. The 17.7% of nurses asked to be moved from the ward, and 6.9% left it; 6.9% respondents had thought to leave the nursing profession; 235 (65.2%) experienced at least one LHs related disorder during the last year. Most reported symptoms were low morale, anxiety, and sleep disturbances. Conclusions. The incidence of LH and related disorders is high in EDs and ICUs, determining a low professional and psycho-physical quality of life.

The aim of this study was to estimate the associations between neighbourhood built environment characteristics and transportation walking (TW), recreational walking (RW), and moderate-intensity (MPA) and vigorous-intensity physical activity (VPA) in adults independent of sociodemographic characteristics and residential self-selection (i.e. the reasons related to physical activity associated with a person's choice of neighbourhood). In 2007 and 2008, 4423 Calgary adults completed land-based telephone interviews capturing physical activity, sociodemographic characteristics and reasons for residential self-selection. Using spatial data, we estimated population density, proportion of green space, path/cycleway length, business density, bus stop density, city-managed tree density, sidewalk length, park type mix and recreational destination mix within a 1.6 km street network distance from the participants' geolocated residential postal code. Generalized linear models estimated the associations between neighbourhood built environment characteristics and weekly neighbourhood-based physical activity participation (≥ 10 minutes/week; odds ratios [ORs]) and, among those who reported participation, duration of activity (unstandardized beta coefficients [B]). The sample included more women (59.7%) than men (40.3%) and the mean (standard deviation) age was 47.1 (15.6) years. TW participation was associated with intersection (OR = 1.11; 95% CI: 1.03 to 1.20) and business (OR = 1.52; 1.29 to 1.78) density, and sidewalk length (OR = 1.19; 1.09 to 1.29), while TW minutes was associated with business (B = 19.24 minutes/week; 11.28 to 27.20) and tree (B = 6.51; 2.29 to 10.72 minutes/week) density, and recreational destination mix (B = -8.88 minutes/ week; -12.49 to -5.28). RW participation was associated with path/cycleway length (OR = 1.17; 1.05 to 1.31). MPA participation was associated with recreational destination mix (OR = 1.09; 1.01 to 1.17) and sidewalk length (OR = 1.10; 1

This study investigated the contribution of child characteristics and parenting environment to the relationship between family SES/demographic characteristics and maternal language to infants.1157 children were drawn from a representative sample of 1292 infants born to mothers in rural Appalachian counties and rural counties in southern minority U.S. communities. Mothers and their 6-8 month old babies were videotaped at home while talking about a wordless picture book. Mothers' language output and complexity were analyzed. Child temperament, age, and parenting environment (knowledge of child development and observed mother-child engagement) were predictors of maternal language. Furthermore, their inclusion reduced the magnitude of the association between demographic characteristics and maternal language. Tests of mediation suggested that the parenting environment partially mediates the relationship between SES/demographic characteristics and maternal language. Findings are discussed with respect to identifying proximal processes that explain how SES may exert its influence on the language of young children.

Study of an optimization approach for a disposal tunnel layout, taking into account the geological environment with spatially heterogeneous characteristics

International Nuclear Information System (INIS)

Suyama, Yasuhiro; Toida, Masaru; Yanagizawa, Koichi

2009-01-01

The geological environment has spatially heterogeneous characteristics with varied host rock types, fractures and so on. In this case the generic disposal tunnel layout, which has been designed by JNC, is not the most suitable for HLW disposal in Japan. The existence of spatially heterogeneous characteristics means that in the repository region there exist sub-regions that are more favourable from the perspective of long-term safety and ones that are less favourable. In order that the spatially heterogeneous environment itself may be utilized most effectively as a natural barrier system, an alternative design of disposal tunnel layout is required. Focusing on the geological environment with spatially heterogeneous characteristics, the authors have developed an alternative design of disposal tunnel layout. The alternative design adopts an optimization approach using a variable disposal tunnel layout. The optimization approach minimizes the number of locations where major water-conducting fractures are intersected, and maximizes the number of emplacement locations for waste packages. This paper will outline the variable disposal tunnel layout and its applicability.

Access to the Superficial Femoral Artery in the Presence of a 'Hostile Groin': A Prospective Study

International Nuclear Information System (INIS)

Marcus, Adrian J.; Lotzof, Kevin; Howard, Adam

2007-01-01

Purpose. Lower limb angioplasty is commonly performed via antegrade common femoral artery (CFA) puncture, followed by selective superficial femoral artery (SFA) catheterization. Arterial access can be complicated by a 'hostile groin' (scarring, obesity, or previous failed CFA puncture). We prospectively investigated color duplex ultrasound (CDU)-guided SFA access for radiological interventions. Methods. Antegrade CDU-guided CFA and SFA puncture were compared in 30 patients requiring intervention for severe leg ischemia who had hostile groins. Demographics, screen time, radiation dose, intervention, and complications were prospectively recorded. Results. Treatment in 30 patients involved 44 angioplasties (40 transluminal, 4 subintimal) and 2 diagnostic angiograms. Fifteen of these patients had CDU-guided CFA punctures; in 8 of these patients CDU-guided CFA puncture 'failed' (i.e., there was failure to pass a guidewire or catheter into the CFA or SFA), necessitating immediate direct CDU-guided SFA puncture. Overall, the mean screen time and radiation dosage, via direct CDU-guided SFA puncture in 30 patients, was 4.8 min and 464 Gy cm 2 respectively. With CDU-guided CFA puncture, mean screen time (10 min), radiation dose (2023 Gy cm 2 ), and complications (13%) were greater when compared with the SFA puncture results overall and in the same patients at subsequent similar procedures (2.7 min, 379 Gy cm 2 (p < 0.05), no complications in this subgroup). Five complications occurred: 2 each at CFA and SFA entry sites, and 1 angioplasty embolus. Conclusions. The CDU-guided SFA puncture technique was both more effective than CDU-guided CFA access in patients with scarred groins, obesity, or failed CFA punctures and safer, with reduced screen times, radiation doses, and complications

The Characteristics of the Exergy Reference Environment and Its Implications for Sustainability-Based Decision-Making

Directory of Open Access Journals (Sweden)

Stephen Murphy

2012-07-01

Full Text Available In the energy realm there is a pressing need to make decisions in a complex world characterized by biophysical limits. Exergy has been promoted as a preferred means of characterizing the impacts of resource consumption and waste production for the purpose of improving decision-making. This paper provides a unique and critical analysis of universal and comprehensive formulations of the chemical exergy reference environment, for the purpose of better understanding how exergy can inform decision-making. Four related insights emerged from the analysis, notably: (1 standard and universal chemical exergy reference environments necessarily encounter internal inconsistencies and even contradictions in their very formulations; (2 these inconsistencies are a result of incompatibility between the exergy reference environment and natural environment, and the desire to model the exergy reference environment after the natural environment so as to maintain analytical relevance; (3 the topics for which exergy is most appropriate as an analytical tool are not well served by comprehensive reference environments, and (4 the inconsistencies point to a need for deeper reflection of whether it is appropriate to adopt a thermodynamic frame of analysis for situations whose relevant characteristics are non-thermodynamic (e.g., to characterize scarcity. The use of comprehensive reference environments may lead to incorrect recommendations and ultimately reduce its appeal for informing decision-making. Exergy may better inform decision-making by returning to process dependent reference states that model specific processes and situations for the purpose of engineering optimization.

Extreme poverty and affluence, the two sides of our world. Energy, raw materials, environment

Energy Technology Data Exchange (ETDEWEB)

Bischoff, G

1987-07-01

The author discusses the different economic situtions in the industrialized and in the developing parts of the world, and the resulting fears of the populations. These feelings of fear and apprehension are traced back to their manifold causes, discussing among others unsecure raw material supply and the damage to the environment, hostile attitudes towards industrial exploitation or technical sciences, the role of the press and other media in the 'making' of fear of life, the fear of becoming slave of the machines. The problems' solution lies in the supply and utilisation of energy, and any efforts towards maintaining our natural environment so that life may go on will have to be based, the author says, on the technological development from nuclear power to thermonuclear fusion.

The use of cognitive enhancement (CE) by means of pharmaceutical agents has been the subject of intense debate both among scientists and in the media. This study investigates several drivers of and obstacles to the willingness to use prescription drugs non-medically for augmenting brain capacity. We conducted a web-based study among 2,877 students from randomly selected disciplines at German universities. Using a factorial survey, respondents expressed their willingness to take various hypothetical CE-drugs; the drugs were described by five experimentally varied characteristics and the social environment by three varied characteristics. Personal characteristics and demographic controls were also measured. We found that 65.3% of the respondents staunchly refused to use CE-drugs. The results of a multivariate negative binomial regression indicated that respondents' willingness to use CE-drugs increased if the potential drugs promised a significant augmentation of mental capacity and a high probability of achieving this augmentation. Willingness decreased when there was a high probability of side effects and a high price. Prevalent CE-drug use among peers increased willingness, whereas a social environment that strongly disapproved of these drugs decreased it. Regarding the respondents' characteristics, pronounced academic procrastination, high cognitive test anxiety, low intrinsic motivation, low internalization of social norms against CE-drug use, and past experiences with CE-drugs increased willingness. The potential severity of side effects, social recommendations about using CE-drugs, risk preferences, and competencies had no measured effects upon willingness. These findings contribute to understanding factors that influence the willingness to use CE-drugs. They support the assumption of instrumental drug use and may contribute to the development of prevention, policy, and educational strategies.

Full Text Available The paper presents two studies aimed at development and validation of a scale of alienation in educational context. The first study using samples of university students (N = 395 and high school students (N = 194 involves structural validation of Subjective Alienation Questionnaire for Students using confirmatory factor analysis. The scales of the questionnaire have shown acceptable internal consistency (α = 0,70–0,92 and predictable associations with measures of subjective and psychological well-being, locus of control, life meaning, generalized self-efficacy, and hardiness. The second study using a sample of university students (N = 152 focused on the associations of alienation, burnout, and academic motivation with learning environment characteristics, well-being, and self-reported academic achievement. According to the resulting model, learning motivation and alienation reflect characteristics of relation of the student to the object of learning, whereas burnout reflects the resulting characteristics of learning process. Burnout was predicted by excessive difficulty of learning tasks, high workload, and alienation. Alienation was predicted by low teacher support, low clarity of learning requirements, and lack of choice in studies. Alienation and burnout mediated the asso-ciations of these learning environment characteristics with self-reported academic success and subjective well-being of students.

Interpersonal discrimination and depressive symptomatology: examination of several personality-related characteristics as potential confounders in a racial/ethnic heterogeneous adult sample

Background Research suggests that reports of interpersonal discrimination result in poor mental health. Because personality characteristics may either confound or mediate the link between these reports and mental health, there is a need to disentangle its role in order to better understand the nature of discrimination-mental health association. We examined whether hostility, anger repression and expression, pessimism, optimism, and self-esteem served as confounders in the association between ...

Full Text Available The Painted Veil (2006 is a love story which takes place in the nineteen twenties, between an Englishman, Dr Walter Fane, a bacteriologist, and Kitty, an English upper class girl, who marry for convenience hardly knowing each other. Soon after the wedding they move to Shangai, where Walter is in charge of a government laboratory. Also in Shangai Kitty meets Charles, a married vice consul with whom she has an affair. When Walter discovers that his wife has been unfaithful to him he threatens to divorce her if she refuses to go with him to a village in Inner China, where there is an outbreak of cholera and where his help is required. They settle on the outskirts of Mei?tan?fu. The relationship between Walter and kitty cannot go worse; they hardly talk to each other, and while Walter is working day and night, trying to stop the spread of cholera, Kitty feels lonely and useless . One day she visits a group of French nuns who collaborate in the hospital and run an orphanage, in which Kitty is finally able to help as a music teacher. The fight against cholera is arduous: customs, religion, and politics make the doctor’s work even harder. It is then that Walter and Kitty discover qualities in each other that they did not know of; finally love and reconciliation emerge. When it seems that the outbreak of cholera is already under control, people from downstream villages, where there is no doctor, arrive. Walter feels obliged to set up a refugee camp on the outskirts of the city, where he finally contracts cholera and dies.

Modelling the droplet interaction in a hostile environment

International Nuclear Information System (INIS)

Foissac, A.

2011-01-01

During the situation of a nuclear reactor cooling loss, the pressure of the containment building may increase due to a release of steam, of gas coming from fission products and also of explosive gas, like di-hydrogen, created by chemical reaction in the primary cooling system. The procedure plan consists in using the spray system, constituted by hundreds of nozzles, in order to decrease pressure and temperature, to wash out fission products and to enhance gas mixing to avoid explosive gas local accumulation. The efficiency of the spray system may depend on the size and the velocity of the spray droplets. These parameters can be modified by collisions, occurring as soon as the spray envelopes overlap. This work models the droplet size and velocity poly-dispersion, and its evolution due to the collisions, then, implements these models in the Eulerian NEPTUNE-CFD code. The sectional method is chosen, and the collision is modeled from the results obtained on an experimental facility for the study of the droplet binary collision under typical conditions of a reactor severe accident. The numerical simulation of the spray system has then been performed, and compared to the experimental results on a large scale bench for characterizing large industrial sprays. A good agreement is obtained. These results provide a first step toward a comprehensive simulation of a whole scenario of a reactor vessel under severe accident conditions with spray activation.

Fredland, Nina M

2008-01-01

Although school violence directly affects the overall health and well-being of children and adolescents, clear priorities have not been identified for dealing with the problem. Horrific events such as the 1999 Columbine High School shooting in Littleton, Colo, and recent shootings at Virginia Tech have focused the nation on high-profile, media-worthy school violence to the detriment of addressing everyday forms of violence in schools. Policies that have been developed to reduce school violence have mixed reviews. To raise the consciousness of healthcare professionals, educators, legislators, and the general public, the most salient issues are discussed.

2015-01-01

The oxidation characteristics of the electron beam surface-treated Alloy 617, which has an Al-rich surface layer, were evaluated in high temperature helium environments. Isothermal oxidation tests were performed in helium (99.999% purity) and VHTR-helium (helium of prototypical VHTR chemistry containing impurities like CO, CO 2 , CH 4 , and H 2 ) environments at 900 °C for up to 1000 h. The surface-treated Alloy 617 showed an initial transient oxidation stage followed by the steady-state oxidation in all test environments. In addition, the steady-state oxidation kinetics of the surface-treated Alloy 617 was 2-order of magnitude lower than that of the as-received Alloy 617 in both helium environments as well as in air. The improvement in oxidation resistance was primarily due to the formation of the protective Al 2 O 3 layer on the surface. The weight gain was larger in the order of air, helium, and VHTR-helium, while the parabolic rate constants (k p ) at steady-state were similar for all test environments. In both helium environments, the oxide structure consisted of the outer transition Al 2 O 3 with a small amount of Cr 2 O 3 and inner columnar structured Al 2 O 3 without an internal oxide. In the VHTR-helium environment, where the impurities were added to helium, the initial transient oxidation increased but the steady state kinetics was not affected

Characteristics of an individual alone cannot exhaustively explain all the causes of poor health, and neighborhood of residence have been suggested to be one of the factors that contribute to health. However, knowledge about aspects of the neighborhood that are most important to health is limited. The main objective of this study was to explore associations between certain features of neighborhood environment and self-rated health and depressive symptoms in Maastricht (The Netherlands). A large amount of routinely collected neighborhood data were aggregated by means of factor analysis to 18 characteristics of neighborhood social and physical environment. Associations between these characteristics and self-rated health and presence of depressive symptoms were further explored in multilevel logistic regression models adjusted for individual demographic and socio-economic factors. The study sample consisted of 9,879 residents (mean age 55 years, 48 % male). Residents of unsafe communities were less likely to report good health (OR 0.88 95 % CI 0.80-0.97) and depressive symptoms (OR 0.81 95 % CI 0.69-0.97), and less cohesive environment was related to worse self-rated health (OR 0.81 95 % CI 0.72-0.92). Residents of neighborhoods with more car traffic nuisance and more disturbance from railway noise reported worse mental health (OR 0.79 95 % CI 0.68-0.92 and 0.85 95 % CI 0.73-0.99, respectively). We did not observe any association between health and quality of parking and shopping facilities, facilities for public or private transport, neighborhood aesthetics, green space, industrial nuisance, sewerage, neighbor nuisance or satisfaction with police performance. Our findings can be used to support development of integrated health policies targeting broader determinants of health. Improving safety, social cohesion and decreasing traffic nuisance in disadvantaged neighborhoods might be a promising way to improve the health of residents and reduce health inequalities.

In the event of a postulated severe accident on a pressurized water reactor (PWR) involving fuel degradation, gases and aerosols containing radioactive products could be released, with short, medium and long term consequences for the population and the environment. Under such accident conditions, the ESCADRE code system, developed at IPSN (Institute for Nuclear Safety and Protection) can be used to calculate the properties of the substances released and, especially with the AEROSOLS/B2 code, the main characteristics of the aerosols (concentration, size distribution, composition). For conditions representative of severe PWR accidents, by varying different main parameters (structural material aerosols, steam condensation in the containment, etc...), indications are given on the range of characteristics of the aerosols (containing notably Cs, Te, Sr, Ru, etc...) released to the atmosphere. Information is also given on how more accurate data (especially on the chemical forms) will be obtainable in the framework of current or planned experimental programs (HEVA, PITEAS, PHEBUS PF, etc...)

Full Text Available Abstract Background Early childhood is critical to the development of lifelong food habits. Given the high proportion of children with inadequate fruit and vegetable consumption, identification of modifiable factors associated with higher consumption may be useful in developing interventions to address this public health issue. This study aimed to identify the characteristics of the home food environment that are associated with higher fruit and vegetable consumption in a sample of Australian preschool children. Methods A cross-sectional telephone survey was conducted with 396 parents of 3 to 5 year-old children attending 30 preschools within the Hunter region, New South Wales, Australia. Children's fruit and vegetable consumption was measured using a valid and reliable subscale from the Children's Dietary Questionnaire. Associations were investigated between children's fruit and vegetable intake and characteristics of the home food environment including parental role-modeling, parental providing behaviour, fruit and vegetable availability, fruit and vegetable accessibility, pressure to eat, family eating policies and family mealtime practices. Characteristics of the home food environment that showed evidence of an association with children's fruit and vegetable consumption in simple regression models were entered into a backwards stepwise multiple regression analysis. The multiple regression analysis used generalised linear mixed models, controlled for parental education, household income and child gender, and was adjusted for the correlation between children's fruit and vegetable consumption within a preschool. Results The multiple regression analysis found positive associations between children's fruit and vegetable consumption and parental fruit and vegetable intake (p = 0.005, fruit and vegetable availability (p = 0.006 and accessibility (p = 0.012, the number of occasions each day that parents provided their child with fruit and vegetables

Berau coal in East Kalimantan; Its petrographics characteristics and depositional environment

Full Text Available http://dx.doi.org/10.17014/ijog.vol2no4.20071To asses the characteristics of the Early to Middle Miocene Berau coal in the Berau Basin, leading to interpretation of coal depositional environments, some fresh outcrop and subcrop samples and also drill cores of the coals have been analyzed microscopically. Coal petrographic analysis was performed on twenty four coal samples from the Middle Miocene Lati Formation. Vitrinite, present in a high value, and ranging between 66.2 - 96.2%, is dominated by vitrinite B. On the other hand, inertinite and exinite, showing a similar value, exist in a low to moderate amount. Vitrinite reflectance, present in a low value, varies from 0.40 - 0.58%. Low mineral matter content is dominated by clay minerals (0.4 - 6.6% with minor pyrite. Transitions from wet and very wet forested swamps to drier conditions with lower tree density are indicated by the higher content of vitrinite B, whilst a reverse trend is indicated by the lower content of vitrinite A. Petrographic indices obtained from facies diagnostic macerals show that an accumulation of the ancient peats under prevailing relatively wet limited influx clastic marsh to very wet forest swamps or moors is considered. The composition of the coal samples supports the interpretation of a system of fluvial to meandering streams in an upper delta plain environment. The original peat-forming vegetation was composed mainly of cellulose rich, shrub-like plants, tree ferns, herbaceous plant communities, with minor amount of trees. Thereby, the organic facies concept is thus applicable in basin studies context and has potential to become an additional tool for depositional environment interpretation.

Permafrost degradation exhibits striking and profound influences on the alpine ecosystem, and response characteristics of vegetation and soil environment to such degradation inevitably differ during the entire degraded periods. However, up to now, the related research is lacking in the Qinghai–Tibetan Plateau (QTP). For this reason, twenty ecological plots in the different types of permafrost zones were selected in the upstream regions of the Shule River Basin on the northeastern margin of the QTP. Vegetation characteristics (species diversity, community coverage and biomass etc) and topsoil environment (temperature (ST), water content (SW), mechanical composition (SMC), culturable microorganism (SCM), organic carbon (SOC) and total nitrogen (TN) contents and so on), as well as active layer thickness (ALT) were investigated in late July 2009 and 2010. A spatial–temporal shifts method (the spatial pattern that is represented by different types of permafrost shifting to the temporal series that stands for different stages of permafrost degradation) has been used to discuss response characteristics of vegetation and topsoil environment throughout the entire permafrost degradation. The results showed that (1) ST of 0–40 cm depth and ALT gradually increased from highly stable and stable permafrost (H-SP) to unstable permafrost (UP). SW increased initially and then decreased, and SOC content and the quantities of SCM at a depth of 0–20 cm first decreased and then increased, whereas TN content and SMC showed obscure trends throughout the stages of permafrost degradation with a stability decline from H-SP to extremely unstable permafrost (EUP); (2) further, species diversity, community coverage and biomass first increased and then decreased in the stages from H-SP to EUP; (3) in the alpine meadow ecosystem, SOC and TN contents increased initially and then decreased, soil sandy fractions gradually increased with stages of permafrost degradation from substable (SSP

Previous studies have demonstrated that justifying the social, economic, and political systems is associated with psychological well-being, which has been termed as the palliative function of ideology. However, little research has been conducted on gender stereotypes among children, comparing by socioeconomic status. This study aimed to fill this gap in the system justification literature. We present data from the Chilean version of the International Survey of Children Well-Being (ISCWeB), which was conducted in 2012. We found that the palliative function of gender stereotypes is present among this sample, being qualified by a socioeconomic status by hostile gender stereotype interaction. In other words, the effect on the psychological well-being was observed in low-status, but not in high-status students. These results extend the previous knowledge about the palliative function of the ideology, suggesting why the low-status members of a society actively engage in system justification. PMID:29046657

Wireless Communication Enhancement Methods for Mobile Robots in Radiation Environments

CERN Document Server

Nattanmai Parasuraman, Ramviyas; Ferre, Manuel

In hostile environments such as in scientific facilities where ionising radiation is a dominant hazard, reducing human interventions by increasing robotic operations are desirable. CERN, the European Organization for Nuclear Research, has around 50 km of underground scientific facilities, where wireless mobile robots could help in the operation of the accelerator complex, e.g. in conducting remote inspections and radiation surveys in different areas. The main challenges to be considered here are not only that the robots should be able to go over long distances and operate for relatively long periods, but also the underground tunnel environment, the possible presence of electromagnetic fields, radiation effects, and the fact that the robots shall in no way interrupt the operation of the accelerators. Having a reliable and robust wireless communication system is essential for successful execution of such robotic missions and to avoid situations of manual recovery of the robots in the event that the robot runs ...

The effects of the space environment on the chlorophyll fluorescence parameters and photosynthesis characteristics of wheat cultivars, Xinong 1043 M1 and Shaan253 M 1 , were studied. The results showed that the decrement of contents of PS II primary photochemical efficiency (F v /F m ), potential activity (F v /F 0 ), photochemical quenching coefficient (qP) and photosynthesis rate (Pn) were less than that of control, increment of non-photochemical quenching coefficient (qN) were more than that of control. The results suggested that photosynthetic apparatus were damaged, photosynthetic electron transport, photosynthetic primary reaction were inhibited, rate of photosynthesis decreased and growth of M 1 plant were retarded, which leading to thousand kernel weights decreased.

Objectives. We examined whether certain characteristics of the social and physical environment influence a child's mode of travel between home and school. Methods. Students aged 11 to 13 years from 21 schools throughout London, Ontario, answered questions from a travel behavior survey. A geographic information system linked survey responses for 614 students who lived within 1 mile of school to data on social and physical characteristics of environments around the home and school. Logistic regression analysis was used to test the influence of environmental factors on mode of travel (motorized vs “active”) to and from school. Results. Over 62% of students walked or biked to school, and 72% from school to home. The likelihood of walking or biking to school was positively associated with shorter trips, male gender, higher land use mix, and presence of street trees. Active travel from school to home was also associated with lower residential densities and lower neighborhood incomes. Conclusions. Our findings demonstrate that active travel is associated with environmental characteristics and suggest that school planners should consider these factors when siting schools in order to promote increased physical activity among students.

To identify characteristics of aeolian activity and the aeolian environment in China's eastern desert region, this study collected surface sediment samples from the main desert and sandy lands in this region: the Hobq Desert and the Mu Us, Otindag, Horqin, and Hulunbuir sandy lands. We analyzed the grain-size characteristics and their relationships to three key environmental indicators: drift potential, the dune mobility index, and vegetation cover. The main sediment components are fine to medium sands, with poor (Hulunbuir) to moderate (all other areas) sorting, of unimodal to bimodal distribution. This suggests that improved sorting is accomplished by the loss of both relatively coarser and finer grains. Since 2000, China's eastern desert region has generally experienced low wind energy environmental conditions, resulting in decreased dune activity. In the Hobq Desert, however, the dry climate and sparse vegetation, in conjunction with the most widely distributed mobile dune area in the eastern desert region, have led to frequent and intense aeolian activity, including wind erosion, sand transport, and deposition, resulting in conditions for good sediment sorting. In the Mu Us, Otindag, and Horqin sandy lands, mosaic distribution has resulted from wind erosion-dominated and deposition-dominated aeolian environments. In the Hulunbuir Sandy Land, high precipitation, low temperatures, and steppe vegetation have resulted in well-developed soils; however, strong winds and flat terrain have created an aeolian environment dominated by wind erosion.

This paper is to investigate the wear behaviors of two types of ceramics, Al 2 O 3 and TiO 2 , by coated plasma thermal spray method under the lubricative environment. The lubricative environments are grease fluids, a general hydraulic fluids, and bearing fluids. The wear testing machine used a pin on disk type. Wear characteristics, which were friction force, friction coefficient and the specific wear rate, according to the lubricative environments were obtained at the four kinds of load, and the sliding velocity is 0.2m/sec. After the wear experiments, the wear surfaces of the each test specimen were observed by a scanning electronic microscope. The obtained results are as follows. : 1. The friction coefficients of TiO 2 coating materials are 0.11 ∼ 0.16 range and those of Al 2 O 3 are 0.24 ∼ 0.39. The friction coefficient of two coating materials is relative to the hardness of these materials. 2. The friction coefficient of TiO 2 coating materials in three lubricative environments is almost same to each other in spite of changing of applied loads. 3. The friction coefficient of Al 2 O 3 coating materials is more large in low load than high load. And the friction coefficient in grease is more large than a general hydraulic and bearing fluids had almost same friction coefficient. 4. The specific wear rate in TiO 2 is greatly increasing according to change the applied loads, but that in Al 2 O 3 is slightly. And the wear in grease is the least among three lubricating environments. 5. On the wear mechanism by SEM image observation, the wear of Al 2 O 3 is adhesive wear and TiO 3 is abrasive wear

Sexual assault affects a large proportion of women in the world. Although most rapes are committed by one man, the act itself may be influenced by many (e.g., the peer group). Hostile sexism (HS) has repeatedly been associated with men's rape proclivity, but the influence exerted by the HS of the peer group on rape proclivity has not been investigated. In this study, we explored the impact of perceived male peer support to HS on participants' rape proclivity. A sample of Spanish undergraduate students from a university in the south of Spain ( N = 134) completed the Ambivalent Sexism Inventory. Immediately afterwards, they received feedback on the supposed sexist responses of a peer group (high vs. low in HS); we kept the benevolent sexism (BS) of the peer group at medium levels. Next, we assessed participants' rape proclivity using acquaintance rape scenarios. Results showed an interaction between participants' own levels of HS and information about the HS of the peer group. Men high in HS reported higher rape proclivity in the high-HS peer-group condition than in the low-HS peer-group condition. By contrast, information on the peer group did not affect self-reported rape proclivity of men low in HS. Results also corroborated the relationship between participants' levels of HS and rape proclivity, and expanded the literature by revealing an unexpected influence of participants' BS on rape proclivity.

Fungal Melanin: What do We Know About Structure?

The production of melanin significantly enhances the virulence of many important human pathogenic fungi. Despite fungal melanin’s importance in human disease, as well as melanin’s contribution to the ability of fungi to survive in diverse hostile environments, the structure of melanin remains unsolved. Nevertheless, ongoing research efforts have progressively revealed several notable structural characteristics of this enigmatic pigment, which will be the focus of this review. These compositio...

Tsunami sediments and their grain size characteristics

Science.gov (United States)

Sulastya Putra, Purna

2018-02-01

Characteristics of tsunami deposits are very complex as the deposition by tsunami is very complex processes. The grain size characteristics of tsunami deposits are simply generalized no matter the local condition in which the deposition took place. The general characteristics are fining upward and landward, poor sorting, and the grain size distribution is not unimodal. Here I review the grain size characteristics of tsunami deposit in various environments: swale, coastal marsh and lagoon/lake. Review results show that although there are similar characters in some environments and cases, but in detail the characteristics in each environment can be distinguished; therefore, the tsunami deposit in each environment has its own characteristic. The local geological and geomorphological condition of the environment may greatly affect the grain size characteristics.

Gait is emerging as a powerful diagnostic and prognostic tool, and as a surrogate marker of disease progression for Parkinson's disease (PD). Accelerometer-based body worn monitors (BWMs) facilitate the measurement of gait in clinical environments. Moreover they have the potential to provide a more accurate reflection of gait in the home during habitual behaviours. Emerging research suggests that measurement of gait using BWMs is feasible but this has not been investigated in depth. The aims of this study were to explore (i) the impact of environment and (ii) ambulatory bout (AB) length on gait characteristics for discriminating between people with PD and age-matched controls. Fourteen clinically relevant gait characteristics organised in five domains (pace, variability, rhythm, asymmetry, postural control) were quantified using laboratory based and free-living data collected over 7 days using a BWM placed on the lower back in 47 PD participants and 50 controls. Free-living data showed that both groups walked with decreased pace and increased variability, rhythm and asymmetry compared to walking in the laboratory setting. Four of the 14 gait characteristics measured in free-living conditions were significantly different between controls and people with PD compared to two measured in the laboratory. Between group differences depended on bout length and were more apparent during longer ABs. ABs ≤ 10s did not discriminate between groups. Medium to long ABs highlighted between-group significant differences for pace, rhythm and asymmetry. Longer ABs should therefore be taken into account when evaluating gait characteristics in free-living conditions. This study provides encouraging results to support the use of a single BWM for free-living gait evaluation in people with PD with potential for research and clinical application.

Operating Characteristics of Statistical Methods for Detecting Gene-by-Measured Environment Interaction in the Presence of Gene-Environment Correlation under Violations of Distributional Assumptions.

Accurately identifying interactions between genetic vulnerabilities and environmental factors is of critical importance for genetic research on health and behavior. In the previous work of Van Hulle et al. (Behavior Genetics, Vol. 43, 2013, pp. 71-84), we explored the operating characteristics for a set of biometric (e.g., twin) models of Rathouz et al. (Behavior Genetics, Vol. 38, 2008, pp. 301-315), for testing gene-by-measured environment interaction (GxM) in the presence of gene-by-measured environment correlation (rGM) where data followed the assumed distributional structure. Here we explore the effects that violating distributional assumptions have on the operating characteristics of these same models even when structural model assumptions are correct. We simulated N = 2,000 replicates of n = 1,000 twin pairs under a number of conditions. Non-normality was imposed on either the putative moderator or on the ultimate outcome by ordinalizing or censoring the data. We examined the empirical Type I error rates and compared Bayesian information criterion (BIC) values. In general, non-normality in the putative moderator had little impact on the Type I error rates or BIC comparisons. In contrast, non-normality in the outcome was often mistaken for or masked GxM, especially when the outcome data were censored.

Strangers on the Doorstep: Hostility and Hospitality in A Distant Shore

Directory of Open Access Journals (Sweden)

Lin Ching-Huan

2016-12-01

Full Text Available This article focuses on the rising hostility against immigrants / refugees and growing demand for hospitality, in both regional and transnational senses, in Caryl Phillips’s novel A Distant Shore, set in a local place in North England. I think that the author, in examining the parallel conditions of being a stranger in a village and an outsider to the nation, shows that the demands of hospitality are similarly urgent whether sought by nationals or foreigners though these are calibrated differently in terms of scales of belonging. My broader argument is that hospitality is an ethical practice of everyday life that requires continual renegotiation. Inspired by Levinasian ethics, I turn to Derrida’s and Rosello’s meditations on hospitality, which emphasise the metaphorical nature of the host-guest relationship and the tension it inscribes between the finiteness of politics and the infinity of ethics. By exploring the complex relationship between politics and ethics as this is made manifest in the literary representations of ordinary British citizens’ everyday practices, I suggest that this novel not only deals with the UK’s domestic tensions of multiculturalism and ethnic conflict, but also critically reflects on its bewildered (but hardly new attitude toward the ongoing transnational integration of the new Europe in the postwar period.

Personal contextual characteristics and cognitions: predicting child abuse potential and disciplinary style.

Rodriguez, Christina M

2010-02-01

According to Social Information Processing theory, parents' cognitive processes influence their decisions to engage in physical maltreatment, although cognitions occur in the context of other aspects of the parents' life. The present study investigated whether cognitive processes (external locus of control, inappropriate developmental expectations) predicted child abuse potential and overreactive disciplinary style beyond personal contextual factors characteristic of the parent (hostility, stress, and coping). 363 parents were recruited online. Results highlight the relative importance of the contextual characteristics (particularly stress, avoidant coping, and irritability) relative to cognitive processes in predicting abuse potential and overreactive discipline strategies, although an external locus of control also significantly contributed. Findings do not support that parents' developmental expectations uniquely predict elevated abuse risk. Results indicate stressed parents who utilize avoidance coping strategies are more likely to use overreactive discipline and report increased abuse potential. Findings are discussed with regard to implications for prevention/intervention efforts.

Investigating the Relation Between Prevalence of Asthmatic Allergy with the Characteristics of the Environment Using Association Rule Mining

2014-10-01

The prevalence of allergic diseases has highly increased in recent decades due to contamination of the environment with the allergy stimuli. A common treat is identifying the allergy stimulus and, then, avoiding the patient to be exposed with it. There are, however, many unknown allergic diseases stimuli that are related to the characteristics of the living environment. In this paper, we focus on the effect of air pollution on asthmatic allergies and investigate the association between prevalence of such allergies with those characteristics of the environment that may affect the air pollution. For this, spatial association rule mining has been deployed to mine the association between spatial distribution of allergy prevalence and the air pollution parameters such as CO, SO2, NO2, PM10, PM2.5, and O3 (compiled by the air pollution monitoring stations) as well as living distance to parks and roads. The results for the case study (i.e., Tehran metropolitan area) indicates that distance to parks and roads as well as CO, NO2, PM10, and PM2.5 is related to the allergy prevalence in December (the most polluted month of the year in Tehran), while SO2 and O3 have no effect on that.

Characteristics and transport of organochlorine pesticides (OCPs) in urban multiple environments, including air, dust, rain, canopy throughfall, and runoff water, are explored in this study. Hexachlorocyclohexanes (HCHs) dominated in both air and rain water, and dichlorodiphenyltrichloroethane (DDT) related substances showed a higher affinity to dust. Relatively high concentrations of DDT and dichlorodiphenyldichloroethylene (DDE) in air, rain and dust imply that technical DDT in the environment has been degrading, and there may be unknown local or regional emission sources that contain DDTs in the study area. Source identification showed that DDTs in Beijing urban environments with a fresh signature may originate from the atmospheric transport from remote areas. The ratio of α-/γ-HCH in dust, rain, canopy throughfall and runoff were close to 1, indicating the possible use of lindane. OCPs in runoff were transported from various sources including rain, dust, and canopy throughfall. In runoff, DDTs and hexachlorobenzene (HCB) were mainly transported from dust, and HCHs were mainly from rain and canopy throughfall.

To investigate whether hospital characteristics not readily susceptible to change (i.e. hospital size, university status, and geographic location) are associated with specific self-reported nurse outcomes. Research often focuses on factors within hospitals (e.g. work environment), which are susceptible to change, rather than on structural factors in their own right. However, numerous assumptions exist about the role of structural factors that may lead to a sense of pessimism and undermine efforts at constructive change. Data was derived from survey questions on assessments of work environment and satisfaction, intention to leave, quality of care and burnout (measured by the Maslach Burnout Inventory), from a population-based sample of 11 000 registered nurses in Sweden. Mixed model regressions were used for analysis. Registered nurses in small hospitals were slightly more likely to rank their working environment and quality of nursing care better than others. For example 23% of staff in small hospitals were very satisfied with the work environment compared with 20% in medium-sized hospitals and 21% in large hospitals. Registered nurses in urban areas, who intended to leave their job, were more likely to seek work in another hospital (38% vs. 32%). While some structural factors were related to nurse-reported outcomes in this large sample, the associations were small or of questionable importance. The influence of structural factors such as hospital size on nurse-reported outcomes is small and unlikely to negate efforts to improve work environment. © 2013 John Wiley & Sons Ltd.

2015-06-15

In this paper, an efficient dynamic reactive motion planning method for an autonomous vehicle in a dynamic environment is proposed. The purpose of the proposed method is to improve the robustness of autonomous robot motion planning capabilities within dynamic, uncertain environments by integrating a virtual plane-based reactive motion planning technique with a sensor fusion-based obstacle detection approach. The dynamic reactive motion planning method assumes a local observer in the virtual plane, which allows the effective transformation of complex dynamic planning problems into simple stationary ones proving the speed and orientation information between the robot and obstacles. In addition, the sensor fusion-based obstacle detection technique allows the pose estimation of moving obstacles using a Kinect sensor and sonar sensors, thus improving the accuracy and robustness of the reactive motion planning approach. The performance of the proposed method was demonstrated through not only simulation studies but also field experiments using multiple moving obstacles in hostile dynamic environments.

Flow sensing in hostile environments is of increasing interest for applications in the automotive, aerospace, and chemical and resource industries. There are thermal and non-thermal approaches for high-temperature flow measurement. Compared to their non-thermal counterparts, thermal flow sensors have recently attracted a great deal of interest due to the ease of fabrication, lack of moving parts and higher sensitivity. In recent years, various thermal flow sensors have been developed to operate at temperatures above 500 °C. Microelectronic technologies such as silicon-on-insulator (SOI), and complementary metal-oxide semiconductor (CMOS) have been used to make thermal flow sensors. Thermal sensors with various heating and sensing materials such as metals, semiconductors, polymers and ceramics can be selected according to the targeted working temperature. The performance of these thermal flow sensors is evaluated based on parameters such as thermal response time, flow sensitivity. The data from thermal flow sensors reviewed in this paper indicate that the sensing principle is suitable for the operation under harsh environments. Finally, the paper discusses the packaging of the sensor, which is the most important aspect of any high-temperature sensing application. Other than the conventional wire-bonding, various novel packaging techniques have been developed for high-temperature application.

The relation of some family characteristics such as cohesion and adaptability with organic risk factors, developmental psychopathology, clinical picture and premorbid adjustment was assessed in the group of 100 hospitalized adolescent patients and families. We found correlation between: some of organic risk factors (pathology of neonatal period, pathology of early childhood), some of indicators of developmental psychopathology (eating disorders, conduct disorders), some of clinical signs (mannerism, grandiosity, hostility, suspciousness, disturbances of content of thinking), premorbid adjustment, and variables related to families, described before. We think that biological variables characterizing child (pathology of neonatal period, pathology of early childhood) have an influence on some family characteristics as independent variable. General system theory and circular thinking support these conclusions. In order to verify them, it is necessary to undertake further investigations, based on other methodology, using this results as preliminary findings.

When grand institutional reforms based on idealized models are stalled by the poor institutional environments and difficult politics which often surround large infrastructure systems in developing countries, partial reforms whose design and implementation take into account the different interests of the key stakeholders can provide valuable and immediate benefits while moving these systems from low- towards higher-level equilibria. Strategically negotiated, experimentally partial and purposefully hybrid, these reforms are based on careful stakeholder analysis and strategic coalition building that avoid rigid positions based on idealized models. Our findings are based on a study of power sector reforms in India, where we performed a micro-level and in-depth analysis of a partial and innovative experiment which has allowed private sector participation in electricity distribution within a hostile institutional environment.

Yin, Hongbiao; Huang, Shenghua; Wang, Wenlan

2016-09-13

Based on an adjusted Job Demands-Resources (JD-R) model that considers the mediation of personal resources, this study examined the relationships between two characteristics of teachers' work environment (i.e., emotional job demands and trust in colleagues) and two indicators of teachers' well-being (i.e., teaching satisfaction and emotional exhaustion). In particular, the study focused on how emotion regulation strategies (i.e., reappraisal and suppression) mediate these relationships. Data collected from a questionnaire survey of 1115 primary school teachers in Hong Kong was analyzed to test the hypothesized relationships. The results of structural equation modeling indicated that: (1) the emotional job demands of teaching were detrimental to teacher well-being, whereas trust in colleagues was beneficial; (2) both emotion regulation strategies mediated the relationships between both emotional job demands and trust in colleagues and teacher well-being; and (3) teachers who tend to use more reappraisal may be psychologically healthier than those tend to adopt more suppression. These findings support the applicability of the JD-R model to school settings and highlight the role of teachers' emotion regulation in teachers' well-being. Implications for the improvement of school environments and teachers' well-being are identified.

Immersive Environments: Using Flow and Sound to Blur Inhabitant and Surroundings

Science.gov (United States)

Laverty, Luke

Following in the footsteps of motif-reviving, aesthetically-focused Postmodern and deconstructivist architecture, purely computer-generated formalist contemporary architecture (i.e. blobitecture) has been reduced to vast, empty sculptural, and therefore, purely ocularcentric gestures for their own sake. Taking precedent over the deliberate relation to the people inhabiting them beyond scaleless visual stimulation, the forms become separated from and hostile toward their inhabitants; a boundary appears. This thesis calls for a reintroduction of human-centered design beyond Modern functionalism and ergonomics and Postmodern form and metaphor into architecture by exploring ecological psychology (specifically how one becomes attached to objects) and phenomenology (specifically sound) in an attempt to reach a contemporary human scale using the technology of today: the physiological mind. Psychologist Dr. Mihaly Csikszentmihalyi's concept of flow---when one becomes so mentally immersed within the current activity and immediate surroundings that the boundary between inhabitant and environment becomes transparent through a form of trance---is the embodiment of this thesis' goal, but it is limited to only specific moments throughout the day and typically studied without regard to the environment. Physiologically, the area within the brain---the medial prefrontal cortex---stimulated during flow experiences is also stimulated by the synthesis of sound, memory, and emotion. By exploiting sound (a sense not typically focused on within phenomenology) as a form of constant nuance within the everyday productive dissonance, the engagement and complete concentration on one's own interpretation of this sensory input affords flow experiences and, therefore, a blurred boundary with one's environment. This thesis aims to answer the question: How does the built environment embody flow? The above concept will be illustrated within a ubiquitous building type---the everyday housing tower

In petroleum production, different types of sensors are required to monitor temperature, pressure, leakage of inflammable gases, etc. These sensors work in very hostile environmental conditions and frequently suffer from abrasion and corrosion problems. Presently perovskite oxide based ceramic materials are increasingly being used for such purposes, due to their highly inert behavior in hostile environment. In the present work, we have developed and characterized alumina based complex perovskite oxide ceramics, Ba{sub 2}AlSnO{sub 5.5}. These ceramics were prepared by solid state reaction process and produced in the form of circular discs by uniaxial pressure compaction technique. Green ceramic bodies were sintered at different sintering temperatures (1200 to 1500 deg. C) in air atmosphere. Structural and microstructural characteristics of sintered Ba{sub 2}AlMO{sub 5.5} were studied by XRD and SEM techniques. Mechanical properties were tested by Vickers microhardness tests. Ceramics sintered in the temperature range 1300 deg. C 1400 deg. C presented best results in terms of microstructural characteristics and mechanical performance. (authors)

Is a perceived supportive physical environment important for self-reported leisure time physical activity among socioeconomically disadvantaged women with poor psychosocial characteristics? An observational study.

Over the past decade, studies and public health interventions that target the physical environment as an avenue for promoting physical activity have increased in number. While it appears that a supportive physical environment has a role to play in promoting physical activity, social-ecological models emphasise the importance of considering other multiple levels of influence on behaviour, including individual (e.g. self-efficacy, intentions, enjoyment) and social (e.g. social support, access to childcare) factors (psychosocial factors). However, not everyone has these physical activity-promoting psychosocial characteristics; it remains unclear what contribution the environment makes to physical activity among these groups. This study aimed to examine the association between the perceived physical environment and self-reported leisure-time physical activity (LTPA) among women living in socioeconomically disadvantaged areas demonstrating different psychosocial characteristics. In 2007-8, 3765 women (18-45 years) randomly selected from low socioeconomic areas in Victoria, Australia, self-reported LTPA, and individual, social and physical environmental factors hypothesised within a social-ecological framework to influence LTPA. Psychosocial and environment scores were created. Associations between environment scores and categories of LTPA (overall and stratified by thirds of perceived environment scores) were examined using generalised ordered logistic regression. Women with medium and high perceived environment scores had 20-38% and 44-70% greater odds respectively of achieving higher levels of LTPA than women with low environment scores. When stratified by thirds of psychosocial factor scores, these associations were largely attenuated and mostly became non-significant. However, women with the lowest psychosocial scores but medium or high environment scores had 76% and 58% higher odds respectively of achieving ≥120 minutes/week (vs. <120 minutes/week) LTPA

The programmable industrial robot on wheels which was built for use in the decontamination of the West Valley nuclear fuel reprocessing facility was further developed to be useful for remote maintenance. The vehicle is supported at the work site by screwjack outriggers to provide the stable base needed for precision work. The robot using a position sensor feels its position at the work site and sets up in its computer a rectilinear coordinate axis frame which is precisely aligned with the work site. It is then able to make precise movements with respect to the work site regardless of inaccuracies in the positioning of the vehicle. When using the robot as a manipulator, the operator can quickly call for a sequence of programmed moves to perform a repetitive part of a work task at a higher speed, with greater precision, with fewer errors and with less operator fatigue

2011-01-01

This study examined masculine gender role stress (MGRS) as a mediator of the relation between adherence to dimensions of a hegemonic masculinity and hostility toward women (HTW). Among a sample of 338 heterosexual men, results indicated that MGRS mediated the relation between adherence to the status and antifemininity norms, but not the toughness norm, and HTW. Adherence to the toughness norm maintained a positive association with HTW. These findings suggest that men's HTW develops via multiple pathways that are associated with different norms of hegemonic masculinity. Implications for the prediction of men's aggression against women are discussed. PMID:21531691

2014-05-01

The DSM-5 currently includes a dissociative-PTSD subtype within its nomenclature. Several studies have confirmed the dissociative-PTSD subtype in both American Veteran and American civilian samples. Studies have begun to assess specific factors which differentiate between dissociative vs. non-dissociative PTSD. The current study takes a novel approach to investigating the presence of a dissociative-PTSD subtype in its use of European victims of sexual assault and rape (N=351). Utilizing Latent Profile Analyses, we hypothesized that a discrete group of individuals would represent a dissociative-PTSD subtype. We additionally hypothesized that levels of depression, anger, hostility, and sleeping difficulties would differentiate dissociative-PTSD from a similarly severe form of PTSD in the absence of dissociation. Results concluded that there were four discrete groups termed baseline, moderate PTSD, high PTSD, and dissociative-PTSD. The dissociative-PTSD group encompassed 13.1% of the sample and evidenced significantly higher mean scores on measures of depression, anxiety, hostility, and sleeping difficulties. Implications are discussed in relation to both treatment planning and the newly published DSM-5. Copyright © 2014 Elsevier Ltd. All rights reserved.

Environment, vulnerability, and gender in Andean ethnomedicine.

Science.gov (United States)

Larme, A C

1998-10-01

In Cuyo Cuyo, in the southern Peruvian highlands, ethnomedicine is rife with images of human vulnerability to a hostile and unpredictable environment. This is represented in the ethnomedical system by a focus on wayras, air- or wind-borne illnesses that enter through vulnerable body openings such as the head, orifices, lower back, and feet. Women are viewed to be more vulnerable, or débil, than men to illness because they have an extra orifice, the vagina, they lose copious amounts of blood, which is thought to be irreplaceable, during childbirth. and because they suffer more negative emotions, which are thought to attract wayras and other illnesses to the body. The relationship of ethnomedical beliefs to the Andean physical and political economic environment is explored within the context of social and economic change. Negative beliefs about women's bodies have negative effects on women's roles and position vis-à-vis men in present day Cuyo Cuyo. Ethnomedical beliefs reflect and reinforce gender inequalities in present day Peru and are part of a cultural ideology that in general devalues women. This case study demonstrates that power is a key dimension in the cultural construction of medical knowledge. whether in non-Western or Western societies.

Full Text Available Based on an adjusted Job Demands-Resources (JD-R model that considers the mediation of personal resources, this study examined the relationships between two characteristics of teachers’ work environment (i.e., emotional job demands and trust in colleagues and two indicators of teachers’ well-being (i.e., teaching satisfaction and emotional exhaustion. In particular, the study focused on how emotion regulation strategies (i.e., reappraisal and suppression mediate these relationships. Data collected from a questionnaire survey of 1115 primary school teachers in Hong Kong was analyzed to test the hypothesized relationships. The results of structural equation modeling indicated that: (1 the emotional job demands of teaching were detrimental to teacher well-being, whereas trust in colleagues was beneficial; (2 both emotion regulation strategies mediated the relationships between both emotional job demands and trust in colleagues and teacher well-being; and (3 teachers who tend to use more reappraisal may be psychologically healthier than those tend to adopt more suppression. These findings support the applicability of the JD-R model to school settings and highlight the role of teachers’ emotion regulation in teachers’ well-being. Implications for the improvement of school environments and teachers’ well-being are identified.

Although previous research has investigated relationships between media consumption, sexism, and rape myth acceptance (RMA), limited research has investigated video games despite their emergence as one of the most popular forms of media entertainment globally. Given that video games typically feature even less diverse and more objectified representations of women than traditional mainstream media, we predicted that there would be relationships between video game consumption and negative beliefs and attitudes about women. In this study, we conducted a survey (N = 351) of male and female adults and used structural equation modeling to analyze relationships among video game consumption, trait interpersonal aggression, ambivalent sexism, and first-order (percentage of false rape accusations) and second-order cultivation effects (RMA). We found support for the hypothesized cultivation model, indicating a relationship between video game consumption and RMA via interpersonal aggression and hostile sexism. Although these findings cannot be interpreted causally, we discuss the implications of these associations and future directions for research. © The Author(s) 2015.

Objectives. We evaluated whether neighborhood characteristics correlated with early neurodevelopment and whether these characteristics confounded the previously reported association between exposure to chlorpyrifos (an organophosphate insecticide) and neurodevelopment. Methods. We obtained prenatal addresses, chlorpyrifos exposure data, and 36-month Psychomotor Development Index (PDI) and Mental Development Index (MDI) scores for a birth cohort in New York City (born 1998–2002). We used data from the 2000 US Census to estimate measures of physical infrastructure, socioeconomic status, crowding, demographic composition, and linguistic isolation for 1-kilometer network areas around each child's prenatal address. Generalized estimating equations were adjusted for demographics, maternal education and IQ, prenatal exposure to tobacco smoke, caretaking environment quality, and building dilapidation. Results. Of 266 children included as participants, 47% were male, 59% were Dominican, and 41% were African American. For each standard deviation higher in neighborhood percent poverty, the PDI score was 2.6 points lower (95% confidence interval [CI] = −3.7, −1.5), and the MDI score was 1.7 points lower (95% CI = −2.6, −0.8). Neighborhood-level confounding of the chlorpyrifos-neurodevelopment association was not apparent. Conclusions. Neighborhood context and chlorpyrifos exposure were independently associated with neurodevelopment, thus providing distinct opportunities for health promotion. PMID:20299657

Field dispersal studies are seldom conducted at regional scales even though reliable information on mid-range dispersal distance is essential for models of colonization. The purpose of this study was to examine the potential distance of dispersal of Rhizophora mangle propagules by comparing deposition density with landscape characteristics of mangrove forests. Propagule density was estimated at various distances to mangrove sources (R. mangle) on beaches in southwestern Florida in both high-and low-energy environments, either facing open gulf waters vs. sheltered, respectively. Remote sensing and Geographic Information Systems were used to identify source forests and to determine their landscape characteristics (forest size and distance to deposition area) for the regression analyses. Our results indicated that increasing density of propagules stranded on beaches was related negatively to the distance of the deposition sites from the nearest stands of R. mangle and that deposition was greatly diminished 2 km or more from the source. Measures of fragmentation such as the area of the R. mangle forests were related to propagule deposition but only in low-energy environments. Our results suggest that geographic models involving the colonization of coastal mangrove systems should include dispersal dynamics at mid-range scales, i.e., for our purposes here, beyond the local scale of the forest and up to 5 km distant. Studies of mangrove propagule deposition at various spatial scales are key to understanding regeneration limitations in natural gaps and restoration areas. Therefore, our study of mid-range propagule dispersal has broad application to plant ecology, restoration, and modeling. ?? Springer 2005.

Studies of ambient noise in shallow water environments off Mexico and Alaska: characteristics, metrics and time-synchronization applications

Science.gov (United States)

Guerra, Melania

Sound in the ocean originates from multiple mechanisms, both natural and anthropogenic. Collectively, underwater ambient noise accumulates valuable information about both its sources and the oceanic environment that propagates this noise. Characterizing the features of ambient noise source mechanisms is challenging, but essential, for properly describing an acoustic environment. Disturbances to a local acoustic environment may affect many aquatic species that have adapted to be heavily dependent on this particular sense for survival functions. In the case of marine mammals, which are federally protected, demand exists for understanding such potential impacts, which drives important scientific efforts that utilize passive acoustic monitoring (PAM) tools to inform regulatory decisions. This dissertation presents two independent studies that use PAM data to investigate the characteristics of source mechanisms that dominate ambient noise in two diverse shallow water environments. The study in Chapter 2 directly addresses the concern of how anthropogenic activities can degrade the effectiveness of PAM. In the Alaskan Beaufort Sea, an environment where ambient noise is normally dominated by natural causes, seismic surveys create impulsive sounds to map the composition of the bottom. By inspecting single-sensor PAM data, the spectral characteristics of seismic survey airgun reverberation are measured, and their contribution to the overall ambient noise is quantified. This work is relevant to multiple ongoing mitigation protocols that rely on PAM to acoustically detect marine mammal presence during industrial operations. Meanwhile, Chapter 3 demonstrates that by analyzing data from multiple PAM sensors, features embedded in both directional and omnidirectional ambient noise can be used to develop new time-synchronization processing techniques for aligning autonomous elements of an acoustic array, a tool commonly used in PAM for detecting and tracking marine mammals.

In this study, petrographic examinations along with proximate, calorific value, ultimate, sulphur form and XRD analyses were performed in order to determine the coal characteristics and the depositional environment of the Miocene Can coals. Seventy coal samples were taken from cores and open pit mines. The investigated Can coals are humic coals and classified as lignite to sub-bituminous coal based on the random huminite reflectance (0.38-0.54% R{sub r}), volatile matter (45.50-62.25 wt.%, daf) and calorific value (3419-6479 kcal/kg, maf). The sulphur content of the Can coals changes from 0.30 up to 12.23 wt.%, and a broad range of ash contents was observed varying between 2.46 wt.% and 41.19 wt.%. Huminite is the most abundant maceral group (74-95 vol.% mmf) consisting of mostly humocollinite (gelinite) which is followed by relatively low liptinite (2-18 vol.% mmf) and inertinite content (2-13 vol.% mmf). In general, major mineral contents of coal samples are clay minerals, quartz, mica, pyrite and feldspar. The Can-Etili lignite basin consists of mainly volcano-clastics, fluviatile and lacustrine clastic sediments and contains only one lignite seam with 17 m average thickness. In order to assess the development of paleo-mires, coal facies diagrams were obtained from maceral composition. According to the Vegetation Index (VI) and Ground Water Index (GWI), the Can coal accumulated in inundated marsh, limnic and swamp environments under a rheotrophic hydrological regime. In general, the facies interpretations are in accordance with the observed sedimentalogical data. (author)

Family environment and child development

Directory of Open Access Journals (Sweden)

Tina Kavčič

2005-04-01

Full Text Available The paper presents an overview of research findings on influence of family environment, especially parental behaviour, on child's development. Contemporary authors question early socialization researchers' claims that family characteristics and parental behaviour have important influence on behaviour of their children. Later researchers examined the size and durability of possible effects of family environment on child development. In addition, they focused on establishing whether it is actually the parental behaviour that influences child's development or, on the contrary, parental behaviour represents mainly a reaction to child's characteristics. Behaviour genetic studies have provided evidence that many traditional measures of family environment, including measures of parental behaviour, show genetic influence, thus reflecting genetically influenced child characteristics. Behaviour geneticists also suggest that environmental influences on child (personality development include predominantly non-shared environment, i.e. individual child's specific experiences, his/her own perceptions and interpretations of objectively same events. Based on empirically determined significant genetic effects on most behavioural traits and inconclusive results of studies on effects of family environment on child development some authors believe that it is not the parents, but rather genetic factor and/or peers who have the key role in child development. With respect to findings of behaviour genetics numerous recent studies of relations between family environment and child development involve child specific measures of (extrafamilial environment and examine the interactions between characteristics of an individual and those of his/her environment.

Full Text Available Introduction: For the mothers included in this study, pregnancy is normal until they are diagnosed with HIV/AIDS. Studies on experiences in hospital environments are scarce. Objective: To understand the experiences of pregnant women living with HIV/AIDS during prenatal attention in two hospitals. Materials and methods: Interpretative phenomenological qualitative study, in which ten women, diagnosed with HIV during pregnancy and selected according to relevance and adequacy, participated. The sample size was established by theoretical saturation. Data were collected during in-depth interviews and analyzed through Colaizzi strategy. Results: Categorizing the hospital environment as a generator of stigma and rejection of pregnant women with HIV/AIDS is part of a research project on living with HIV/AIDS during pregnancy. The hospital environment shows the spaces and actors around these mothers during diagnosis and treatment of this infection. Participants refer to the first stage as “accidental diagnosis” and described attention as full of “reckless professionals”. Conclusions: Attitudes and behaviors of health professionals can generate a hostile environment for pregnant women with HIV/AIDS, heightening negative feelings, fears and uncertainties. However, they can also offer a friendly and human scenario that contributes to care and trust between professionals and pregnant women, thus helping mothers to cope with this complex experience.

Anime Landscapes as a Tool for Analyzing the Human–Environment Relationship: Hayao Miyazaki Films

Directory of Open Access Journals (Sweden)

Sema Mumcu

2018-04-01

Full Text Available Common dualistic thinking in environmental design education adopts humans and the environment as separate entities, with the environment as raw material stock. This approach affects the intellectual development of landscape architects and limits their ability to create meaningful landscapes. Therefore, it is necessary to explore and highlight new ideas about the more integrated human–environment relationship. Through the films of Hayao Miyazaki, many audiences around the world have encountered a different worldview. By contrast with Western thinking, which adopts human superiority to nature, the worldview that Miyazaki reflects in his films depicts human as an inseparable part of nature. Being inspired by different communities and their relationship to nature in Miyazaki’s films, we propose using anime as a means of analyzing the human–environment relationship. We classified landscapes based on power relations between humans and nature. We explored how communities shape their physical environment based on how they socially construct nature and the resulting landscapes. Thus, through apocalyptic landscapes, the bitter results of exploiting nature were depicted. Wilderness landscapes reflect the bias humanity has about nature as wild and hostile. Responsible landscapes were introduced asway of understanding the unbreakable bond between humans and the environment. Through these animated landscape types, the ways landscape architecture should approach nature in professional practices was discussed, and the importance of creating responsible landscapes was emphasized.

Remote Mine Detection Technologies for Land and Water Environments

Energy Technology Data Exchange (ETDEWEB)

Hoover, Eddie R.

1999-05-11

The detection of mines, both during and after hostilities, is a growing international problem. It limits military operations during wartime and unrecovered mines create tragic consequences for civilians. From a purely humanitarian standpoint an estimated 100 million or more unrecovered mines are located in over 60 countries worldwide. This paper presents an overview of some of the technologies currently being investigated by Sandia National Laboratories for the detection and monitoring of minefields in land and water environments. The three technical areas described in this paper are: 1) the development of new mathematical techniques for combining or fusing the data from multiple sources for enhanced decision-making; 2) an environmental fate and transport (EF&T) analysis approach that is central to improving trace chemical sensing technique; and 3) the investigation of an underwater range imaging device to aid in locating and characterizing mines and other obstacles in coastal waters.

PURPOSE The provision of breastfeeding support in the neonatal intensive care unit (NICU) may assist a mother to develop a milk supply for the NICU infant. Human milk offers unique benefits and its provision unique challenges in this highly vulnerable population. The provision of breastfeeding support in this setting has not been studied in a large, multihospital study. We describe the frequency of breastfeeding support provided by nurses and examined relationships between NICU nursing characteristics, the availability of a lactation consultant (LC), and breastfeeding support. SUBJECTS AND DESIGN This was a secondary analysis of 2008 survey data from 6060 registered nurses in 104 NICUs nationally. Nurse managers provided data on LCs. These NICUs were members of the Vermont Oxford Network, a voluntary quality and safety collaborative. METHODS Nurses reported on the infants (n = 15,233) they cared for on their last shift, including whether breastfeeding support was provided to parents. Breastfeeding support was measured as a percentage of infants on the unit. The denominator was all infants assigned to all nurse respondents on that NICU. The numerator was the number of infants that nurses reported providing breastfeeding support. Nurses also completed the Practice Environment Scale of the Nursing Work Index (PES-NWI), a nationally endorsed nursing care performance measure. The NICU nursing characteristics include the percentages of nurses with a BSN or higher degree and with 5 or more years of NICU experience, an acuity-adjusted staffing ratio, and PES-NWI subscale scores. Lactation consultant availability was measured as any/none and in full-time equivalent positions per 10 beds. RESULTS The parents of 14% of infants received breastfeeding support from the nurse. Half of the NICUs had an LC. Multiple regression analysis showed a significant relationship between 2 measures of nurse staffing and breastfeeding support. A 1 SD higher acuity-adjusted staffing ratio was

APPLICATION OF GIS AND STATISTICAL METHODS IN ESTABLISHMENT OF THE RELATIONSHIPS BETWEEN GEOCHEMICAL CHARACTERISTICS OF THE ENVIRONMENT AND GEOGRAPHICAL DISTRIBUTION OF DISEASE INCIDENCE RATE

Full Text Available Geochemical environment can influence human health causing chronic medical problems related to long-term, low-level exposures to toxic agents such are trace elements. Humans can be directly exposed to toxic substances by inhalation of air dust or indirectly through food chain or by consumption of local water for drinking, cooking, personal hygiene and recreational purposes. Chronic medical problems related to geochemical characteristics of the environment can also be caused by chronic deficit of chemical elements essential for humans. In this paper we will present several applications of the GIS and statistical methods for relating the geographical distribution of diseases with geochemical characteristics of the environment. In addition, we are presenting methods applied for distinguishing natural distribution of elements from anthropogenic contribution, which is important information for establishing protective measures necessary for decreasing the health risk (the paper is published in Croatian.

Identification of Mn oxides in natural Mn coatings is very difficult due to their poor crystallinity, fine grains, complex chemistry and tiny amounts. In this work, we investigated three types of Mn coatings including rock varnish, dendrite and soil Fe-Mn cutan from different weathering environments in China. Optical microscope, scanning electron microscope, energy dispersive X-ray spectroscopy and micro-Raman spectrometer were employed to achieve non-destructive, sensitive, in-situ and micro analysis on their mineral assemblages, micromorphological features and elemental distribution characteristics. The observed results suggest that rock varnish and soil cutan comprise birnessite, while dendrite is mainly composed of hollandite. Rock varnish with a layered structure has a clear boundary with its substrate, and microlaminations which arise from the fluctuations in Mn content (6.42-17.07 wt%) within the sample profile are obvious on closer inspection. Branch-like dendrite is rich in Mn (32.53-42.96 wt%) but poor in Si and Al, which shows a pilotaxitic texture with its substrate. Soil Fe-Mn cutan can be further divided into an outer black Mn-rich (8.26-13.58 wt%) belt and an inner yellowish-brown Fe-rich (2.06-4.85 wt%) belt, and a clear border can be identified between these two belts. Mn in the substrate of rock varnish and soil cutan is below detection limit while it can be detected in the substrate of dendrite (1.43-7.83 wt%). Our in-situ analysis provides more precise results than traditional powder test. These mineralogical characteristics indicate that dendrite is most likely endogenic, while rock varnish and soil cutan are external accretion formed under different weathering environments.

Tremoureux, Yves

1978-01-01

This research thesis aimed at improving knowledge in the field of stress-free corrosion of alloys with high mechanical characteristics in aqueous environments, at highlighting some necessary aspects of their behaviour during cleaning or disinfection, and at selecting alloys which possess a good stress-free corrosion resistance in view of a later investigation of their stress corrosion resistance. After a presentation of the metallurgical characteristics of high mechanical strength alloys and the report of a bibliographical study on corrosion resistance of these alloys, the author presents and discusses the results obtained in the study of a possible migration of metallic ions in a milk product which is submitted to a centrifugation, and of the corrosion resistance of selected alloys with respect to the different media they will be in contact with during ultra-centrifugation. The following alloys have been used in this research: Marval 18, Marphynox, Marval X12, 17-4PH steel, Inconel 718 [fr

Role of Pre-Course Student Characteristics on Student Learning in Interactive Teaching Environments

Miller, Kelly Anne

The goal of this dissertation is to broaden our understanding of interactive teaching strategies, in the context of the introductory physics classroom at the undergraduate level. The dissertation is divided into four main projects, each of which investigates a specific aspect of teaching physics interactively. All four projects look towards improving the effectiveness of interactive teaching by understanding how pre-course student characteristics affect the way students learn interactively. We first discuss lecture demonstrations in the context of an interactive classroom using Peer Instruction. We study the role of predictions in conceptual learning. We examine how students' predictions affect what they report having seen during a demonstration. We also examine how student predictions affect what they recall as the outcome of the demonstration at the end of the semester. We then analyze student response patterns to conceptual questions posed during Peer Instruction. We look at the relationship between a student's tendency to switch their answer and pre-course student characteristics like science self-efficacy. Next we elucidate response timing to conceptual questions posed over the course of the semester, in two introductory physics classes taught using Peer Instruction. We look at the relationship between student response times and student characteristics like pre-course physics knowledge, science self-efficacy and gender. We study response times as a way of gaining insight into students thinking in Peer Instruction environments as well as to improve the implementation of Peer Instruction. Finally, we present work on the role of NB, an online collaborative textbook annotation tool, in a flipped, project based, physics class. We analyze the relationship between students' level of online engagement and traditional learning metrics to understand the effectiveness of NB in the context of flipped classrooms. We also report the results of experiments conducted to

There is wide agreement that there is a lack of attention to health in municipal environmental policy-making, such as urban planning and regeneration. Explanations for this include differing professional norms between health and urban environment professionals, system complexity and limited evidence for causality between attributes of the built environment and health outcomes. Data from urban health indicator (UHI) tools are potentially a valuable form of evidence for local government policy and decision-makers. Although many UHI tools have been specifically developed to inform policy, there is poor understanding of how they are used. This study aims to identify the nature and characteristics of UHI tools and their use by municipal built environment policy and decision-makers. Health and social sciences databases (ASSIA, Campbell Library, EMBASE, MEDLINE, Scopus, Social Policy and Practice and Web of Science Core Collection) will be searched for studies using UHI tools alongside hand-searching of key journals and citation searches of included studies. Advanced searches of practitioner websites and Google will also be used to find grey literature. Search results will be screened for UHI tools, and for studies which report on or evaluate the use of such tools. Data about UHI tools will be extracted to compile a census and taxonomy of existing tools based on their specific characteristics and purpose. In addition, qualitative and quantitative studies about the use of these tools will be appraised using quality appraisal tools produced by the UK National Institute for Health and Care Excellence (NICE) and synthesised in order to gain insight into the perceptions, value and use of UHI tools in the municipal built environment policy and decision-making process. This review is not registered with PROSPERO. This systematic review focuses specifically on UHI tools that assess the physical environment's impact on health (such as transport, housing, air quality and greenspace

Channel Characteristics and Performance of MIMO E-SDM Systems in an Indoor Time-Varying Fading Environment

Directory of Open Access Journals (Sweden)

Huu Phu Bui

2010-01-01

Full Text Available Multiple-input multiple-output (MIMO systems employ advanced signal processing techniques. However, the performance is affected by propagation environments and antenna characteristics. The main contributions of the paper are to investigate Doppler spectrum based on measured data in a typical meeting room and to evaluate the performance of MIMO systems based on an eigenbeam-space division multiplexing (E-SDM technique in an indoor time-varying fading environment, which has various distributions of scatterers, line-of-sight wave existence, and mutual coupling effect among antennas. We confirm that due to the mutual coupling among antennas, patterns of antenna elements are changed and different from an omnidirectional one of a single antenna. Results based on the measured channel data in our measurement campaigns show that received power, channel autocorrelation, and Doppler spectrum are dependent not only on the direction of terminal motion but also on the antenna configuration. Even in the obstructed-line-of-sight environment, observed Doppler spectrum is quite different from the theoretical U-shaped Jakes one. In addition, it has been also shown that a channel change during the time interval between the transmit weight matrix determination and the actual data transmission can degrade the performance of MIMO E-SDM systems.

Siu, Heidi; Spence Laschinger, Heather K; Finegan, Joan

2008-05-01

The aim of this study was to examine the impact of nurses' perceived professional practice environment on their quality of nursing conflict management approaches and ultimately their perceptions of unit effectiveness from the perspective of Deutsch's theory of constructive conflict management. Rising reports of hostility and conflict among Canadian nurses are a concern to nurses' health and the viability of effective patient care delivery. However, research on the situational factors that influence nurses' ability to apply effective conflict resolution skills that lead to positive results in practice is limited. A nonexperimental, predictive design was used in a sample of 678 registered nurses working in community hospitals within a large metropolitan area in Ontario. The results supported a modified version of the hypothesized model [chi2(1) = 16.25, Goodness of Fit = 0.99, Comparative Fit Index = 0.98, Root-Mean-Square Error of Approximation = 0.15] linking professional practice environment and core self-evaluation to nurses' conflict management and, ultimately, unit effectiveness. Professional practice environment, conflict management, and core-self evaluation explained approximately 46.6% of the variance in unit effectiveness. Positive professional practice environments and high core self-evaluations predicted nurses' constructive conflict management and, in turn, greater unit effectiveness.

The CMS Silicon tracker consists of 70 m 2 of microstrip sensors which design will be finalized at the end of 1999 on the basis of systematic studies of device characteristics as function of the most important parameters. A fundamental constraint comes from the fact that the detector has to be operated in a very hostile radiation environment with full efficiency. We present an overview of the current results and prospects for converging on a final set of parameters for the silicon tracker sensors

Men's hostile sexism and biased perceptions of intimate partners: fostering dissatisfaction and negative behavior in close relationships.

Science.gov (United States)

Hammond, Matthew D; Overall, Nickola C

2013-12-01

Hostile sexism (HS) expresses attitudes that characterize women who challenge men's power as manipulative and subversive. Does endorsing HS negatively bias perceptions of women's behavior and, in turn, create animosity within intimate relationships? Committed heterosexual couples reported on their own behavior and perceptions of their partner's behavior five times across a year (Study 1) and daily for 3 weeks (Study 2). Men who more strongly endorsed HS perceived their partner's behavior as more negative than was justified by their partner's reports. Furthermore, more negative perceptions of the partner's behavior mediated the links between men's HS and feeling more manipulated by their partners, behaving more negatively toward their partners, and lower relationship quality. This indicates that men who endorse HS behave more negatively toward intimate partners and experience lower relationship satisfaction because their antagonistic attitudes toward women in general permeate the way they perceive those partners.

Shock absorber

2013-01-01

A current-voltage characteristic of direct current (DC) gas discharge operated in a micro gas jet injected into a secondary electron microscope (SEM) chamber is presented. Ar gas was injected through a 30 μm orifice gas nozzle (OGN) and was evacuated by an additional pump to keep the high vacuum environment. Gas discharges were ignited between the OGN as anode and a counter electrode of Si wafer. The discharge was self-pulsating in most of the cases while it was stable at lower pressure, larger gap length, and larger time averaged current. The self-pulsating discharge was oscillated by the RC circuit consisting of a stray capacitor and a large ballast resistor. The real time plots of voltage and current during the pulsating was investigated using a discharge model.

Mechanical reliability assessment of optical fibres in Radiation environments

International Nuclear Information System (INIS)

Van Uffelen, M.

2006-01-01

After more than two decades of intensive research and even some pioneering applications in space, optical fibres are now finding their way in various radiation environments, including both fission and future fusion nuclear-power plants, and high-energy physics experiments. For example, next to distributed monitoring applications of large nuclear infrastructures, fibre-optics can also be used for data communications during maintenance operations in the reactor vessel of the future ITER (International Thermonuclear Experimental Reactor), or for plasma diagnostics applications during operation of the reactor. These maintenance and diagnostics tasks require the optical fibres to withstand extremely high doses of radiation, up to MGy dose levels and temperatures above 150 degrees Celsius. The reliability assessment of fibre-optic systems for their qualification in nuclear environments often requires to meet stringent radiation tolerance levels. The majority of (usually accelerated) radiation assessments have so far focused on optical properties, such as wavelength-dependent radiation induced attenuation and radio-luminescence. The relation of these radiation effects with the fabrication methods and other environmental parameters has been the subject of years of research. Only a few results are available on the long-term evolution of mechanical properties of irradiated optical fibres. As a first step towards understanding the long-term reliability of fibre-optic composite cables in hostile radiation environments, we therefore performed dynamic fatigue tests with different commercial-grade optical fibres, both multi-mode and single-mode types

Rail trails are elements of the built environment that support the Task Force on Community Preventive Services' recommendation to create, or enhance access to, places for physical activity (PA). The purpose of this study was to examine the associations between sociodemographic characteristics and perceptions of the built environment with the frequency, type, and duration of PA among users of an urban, paved rail trail segment. Interviewers conducted intercept surveys with 431 rail trail users and analyzed data by using logistic regression to estimate odds ratios between sociodemographic characteristics and perceptions of the built environment on the frequency, type, and duration of PA performed on the trail. Adults who used the trail in the cool months, traveled to the trail by a motorized vehicle, used the trail with others, and had some graduate school education visited the trail less often. Younger adults, men, whites, and those with some graduate school education were more likely to engage in vigorous activities on the trail. Adults who traveled to the trail by a motorized vehicle spent more time engaged in PA on the trail. Our results suggest that the most frequent users of a rail trail for PA are those who use the trail alone and travel to the trail by bicycle or on foot. Trails are an aspect of the built environment that supports active lifestyles, and future studies should evaluate different types of trails among more diverse populations and locations.

To explore the mechanisms through which nurse practice environment dimensions are associated with job outcomes and nurse-assessed quality of care. Mediating variables tested included nurse work characteristics of workload, social capital, decision latitude, as well as burnout dimensions of emotional exhaustion, depersonalization, and personal accomplishment. Acute care hospitals face daily challenges to their efforts to achieve nurse workforce stability, safety, and quality of care. A body of knowledge shows a favourably rated nurse practice environment as an important condition for better nurse and patient outcome variables; however, further research initiatives are imperative for a clear understanding to support and guide the practice community. Cross-sectional survey. Grounded on previous empirical findings, a structural equation model designed with valid measurement instruments was tested. The study population was registered acute care nurses (N=1201) in two independent hospitals and one hospital group with six hospitals in Belgium. Nurse practice environment dimensions predicted job outcome variables and nurse ratings of quality of care. Analyses were consistent with features of nurses' work characteristics including perceived workload, decision latitude, and social capital, as well as three dimension of burnout playing mediating roles between nurse practice environment and outcomes. A revised model adjusted using various fit measures explained 52% and 47% of job outcomes and nurse-assessed quality of care, respectively. The study refines understanding of the relationship between aspects of nursing practice in order to achieve favourable nursing outcomes and offers important concepts for managers to track in their daily work. The findings of this study indicate that it is important for clinicians and leaders to consider how nurses are involved in decision-making about care processes and tracking outcomes of care and whether they are able to work with

Coal combustion by products are a major source of arsenic mobilization in the environment. These by products have been successfully used in the reclamation of mine lands. However, there are concerns about the potential pollution problems from As by such use. A field experiment was established on a recently remined abandoned mine land where fly ashes from three different power plants were used for reclaiming mine soils. The experiment had seven treatments and 4 replications which were arranged in a randomized block design. The treatments consisted of 3 fly ashes at 2 rates each and a check treatment received lime. Arsenic content of the fly ashes varied between 53 and 220 mg/kg. Fly ashes also varied in the amounts of amorphous oxides of iron and neutralization potential. Arsenic concentrations were monitored in the vegetation, soil solutions, and soils. The results of this experiment showed that arsenic concentrations were higher in plants grown on plots receiving fly ash than in plants grown on plots receiving lime treatment. Arsenic concentrations in the plants, water, or soil were not governed by the arsenic content of fly ashes. Arsenic mobilization from the ashes was controlled by the chemical and morphological characteristics of the fly ashes and chemical transformations in the arsenic containing components in soil

Characteristics of the work environment related to older employees' willingness to continue working: intrinsic motivation as a mediator.

2011-08-01

The relationships between older employees' willingness to continue working and characteristics of the work environment for older workers were investigated, as well as a possible mediation by intrinsic motivation. 103 employees ages 50 to 65 years, from various sectors of the Dutch labor market, completed questionnaires that measured willingness to continue working, intrinsic motivation, organizational stimulation, work variety, work challenge, and job autonomy. Hierarchical regression analyses showed organizational stimulation, as well as the various job characteristics, were positively related to employees' willingness to continue working. Moreover, intrinsic motivation fully mediated the relationship of work variety with willingness to continue working and partially mediated the relationships of organizational stimulation, work challenge, and job autonomy with willingness to continue working. It was concluded that organizations can encourage older workers to work until age 65 and beyond by shifting their focus from extrinsic to intrinsic rewards.

Effects of interpretation training on hostile attribution bias and reactivity to interpersonal insult.

Hawkins, Kirsten A; Cougle, Jesse R

Research suggests that individuals high in anger have a bias for attributing hostile intentions to ambiguous situations. The current study tested whether this interpretation bias can be altered to influence anger reactivity to an interpersonal insult using a single-session cognitive bias modification program. One hundred thirty-five undergraduate students were randomized to receive positive training, negative training, or a control condition. Anger reactivity to insult was then assessed. Positive training led to significantly greater increases in positive interpretation bias relative to the negative group, though these increases were only marginally greater than the control group. Negative training led to increased negative interpretation bias relative to other groups. During the insult, participants in the positive condition reported less anger than those in the control condition. Observers rated participants in the positive condition as less irritated than those in the negative condition and more amused than the other two conditions. Though mediation of effects via bias modification was not demonstrated, among the positive condition posttraining interpretation bias was correlated with self-reported anger, suggesting that positive training reduced anger reactivity by influencing interpretation biases. Findings suggest that positive interpretation training may be a promising treatment for reducing anger. However, the current study was conducted with a non-treatment-seeking student sample; further research with a treatment-seeking sample with problematic anger is necessary. Copyright © 2013.

Predictors of Exceptional Longevity: Effects of Early-Life Childhood Conditions, Midlife Environment and Parental Characteristics.

Science.gov (United States)

Gavrilov, Leonid A; Gavrilova, Natalia S

Knowledge of strong predictors of mortality and longevity is very important for actuarial science and practice. Earlier studies found that parental characteristics as well as early-life conditions and midlife environment play a significant role in survival to advanced ages. However, little is known about the simultaneous effects of these three factors on longevity. This ongoing study attempts to fill this gap by comparing centenarians born in the United States in 1890-91 with peers born in the same years who died at age 65. The records for centenarians and controls were taken from computerized family histories, which were then linked to 1900 and 1930 U.S. censuses. As a result of this linkage procedure, 765 records of confirmed centenarians and 783 records of controls were obtained. Analysis with multivariate logistic regression found that parental longevity and some midlife characteristics proved to be significant predictors of longevity while the role of childhood conditions was less important. More centenarians were born in the second half of the year compared to controls, suggesting early origins of longevity. We found the existence of both general and gender-specific predictors of human longevity. General predictors common for men and women are paternal and maternal longevity. Gender-specific predictors of male longevity are the farmer occupation at age 40, Northeastern region of birth in the United States and birth in the second half of year. A gender-specific predictor of female longevity is surprisingly the availability of radio in the household according to the 1930 U.S. census. Given the importance of familial longevity as an independent predictor of survival to advanced ages, we conducted a comparative study of biological and nonbiological relatives of centenarians using a larger sample of 1,945 validated U.S. centenarians born in 1880-95. We found that male gender of centenarian has significant positive effect on survival of adult male relatives

Due to the importance of petroleum and its derivatives for modern society, it is necessary to develop technologies that improve processes and transports of petroleum. The crude oil creates hostile environments and in the process of transport and storage of petroleum are used metallic materials, which corrode becoming a critical problem in this industry. One way of solving this problem is the use of ceramics based on alumina as inert coating on hostile environments. In this work was studied a structure, microstructure and mechanical properties of ceramic composite based on Al2O3 - TiO2 reinforced Ho2O3. The composites were produced by a thermomechanical process, sintered at 1350°C, were analyzed by x-ray diffraction, optical microscopy, scanning electron microscopy, and microhardness. Analyses were performed before and after immersion in earth and offshore crude petroleum to study stability of the developed composites and concluded that the ceramic composites immersed in petroleum show stable in hostile environments.

Methane impurity production in the fusion reactor environment

International Nuclear Information System (INIS)

Dawson, P.T.

1984-11-01

Fusion requires temperatures of the order of 10 8 degrees C. In order to attain the required temperature it will be essential to minimise the energy losses from the plasma. Impurities are a major cause of plasma cooling. Ionization of impurity species in the plasma leads to a subsequent decay and emission of radiation. The most common low Z contaminants to be consideed are water and methane produced by reaction of hydrogen isotopes with oxygen and carbon. This review focuses on the methane production problem. We will be concerned with the sources of carbon in the reactor and also with the reactivity of carbon with hydrogen molecules, atoms and ions and the synergistic effects which can arise from coincident fluxes of electrons and photons and the effects of radiation-induced damage of the materials involved. While the reactor first wall will provide the most hostile environment for methane producton, most of the reactions discussed can occur in breeder blankets and also in other tritium facilities such as fuel handling, purification and storage facilities

Despite the majority of RNs perceiving a shortage of nurses, findings from the 2008 National Survey of RNs indicate the hospital workplace improved in several areas compared to a 2006 survey. Improvements included the time RNs spend with patients, quality of nursing care, and a decreasing impact of the shortage on delaying nurses' responses to pages or calls, staff communication, patients' wait time for surgery, and timeliness and efficiency of care. Areas the environment was perceived to have worsened included overtime hours, sexual harassment/hostile, and physical violence. RNs hold mixed views about the consequences of reporting errors and mistakes with a majority agreeing that reporting them had led to positive changes to prevent future errors, but that mistakes were held against them. Overall, results suggest that hospital managers can be reassured that their efforts to improve the workplace environment are having their intended effect but, at the same time, important areas for improvement remain.

This study examined genetic and environmental influences on harsh parenting of adopted 9-month-olds (N = 503), with an emphasis on positive child-, parent-, and family-level characteristics. Evocative gene-environment correlation (rGE) was examined by testing the effect of both positive and negative indices of birth parent temperament on adoptive parents' harsh parenting. Adoptive fathers' harsh parenting was inversely related to birth mother positive temperament, indicating evocative rGE, as well as to marital quality. Adoptive parents' negative temperamental characteristics were related to hostile parenting for both fathers and mothers. Findings support the importance of enhancing positive family characteristics in addition to mitigating negative characteristics, as well as engaging multiple levels of the family system to prevent harsh parenting. © 2015 The Authors.

Miner-Rubino, Kathi; Cortina, Lilia M

2007-09-01

The present study tested a model examining 2 indicators of a hostile interpersonal workplace climate for women-observed hostility (i.e., incivility and sexual harassment) toward women and perceived organizational unresponsiveness to sexual harassment--and how they relate to well-being and withdrawal for employees. Participants included 871 female and 831 male employees from a public university. According to structural equation analyses, observing hostility toward women and perceiving the organization as lax about harassment predict lower well-being, which translates into higher organizational withdrawal for both female and male employees. Results hold even after controlling for personal mistreatment, negative affectivity, and observed hostility toward men. These findings suggest that working in a misogynistic environment can have negative effects for all employees. (c) 2007 APA.

1996-01-01

Work was carried out on two topics of principal importance to current progress in virtual environment research at NASA Ames and elsewhere. The first topic was directed at maximizing the temporal dynamic response of visually presented Virtual Environments (VEs) through reorganization and optimization of system hardware and software. The final results of this portion of the work was a VE system in the Advanced Display and Spatial Perception Laboratory at NASA Ames capable of updating at 60 Hz (the maximum hardware refresh rate) with latencies approaching 30 msec. In the course of achieving this system performance, specialized hardware and software tools for measurement of VE latency and analytic models correlating update rate and latency for different system configurations were developed. The second area of activity was the preliminary development and analysis of a novel kinematic architecture for three Degree Of Freedom (DOF) haptic interfaces--devices that provide force feedback for manipulative interaction with virtual and remote environments. An invention disclosure was filed on this work and a patent application is being pursued by NASA Ames. Activities in these two areas are expanded upon below.

In order for such learning to take place in distributed environments, knowledge has to be shared among organizational members at different locations and units. This paper reports on a study conducted in the context of drilling and well operations on the Norwegian Continental Shelf, which represents a high-risk distributed organizational environment. The study investigates the relationships between organizations' abilities to learn from failures, knowledge exchange within and between organizational units, quality of contractor relationship management, and work characteristics. The results show that knowledge exchange between units is the most important predictor of perceived ability to learn from failures. Contractor relationship management, leadership involvement, role clarity, and empowerment are also important factors for failure-based learning, both directly and through increased knowledge exchange. The results of the study enhance our understanding of how abilities to learn from failures can be improved in distributed environments where similar work processes take place at different locations and involve employees from several companies. Theoretical contributions and practical implications are discussed. - Highlights: • We investigate factors affecting failure-based learning in distributed environments. • Knowledge exchange between units is the most important predictor. • Contractor relationship management is positively related to knowledge exchange. • Leadership involvement, role clarity, and empowerment are significant variables. • Respondents from an operator firm and eight contractors are included in the study

In this paper, a characteristic of parallel algorithm is presented for solving an elliptic type equation of CUPID via domain decomposition method using the MPI and the parallel performance is estimated in terms of a scalability which shows the speedup ratio. In addition, the time-consuming pattern of major subroutines is studied. Two different grid systems are taken into account: 40,000 meshes for coarse system and 320,000 meshes for fine system. Since the matrix of the CUPID code differs according to whether the flow is single-phase or two-phase, the effect of matrix shape is evaluated. Finally, the effect of the preconditioner for matrix solver is also investigated. Finally, the hybrid (OpenMP+MPI) parallel algorithm is introduced and discussed in detail for solving pressure solver. Component-scale thermal-hydraulics code, CUPID has been developed for two-phase flow analysis, which adopts a three-dimensional, transient, three-field model, and parallelized to fulfill a recent demand for long-transient and highly resolved multi-phase flow behavior. In this study, the parallel performance of the CUPID code was investigated in terms of scalability. The CUPID code was parallelized with domain decomposition method. The MPI library was adopted to communicate the information at the neighboring domain. For managing the sparse matrix effectively, the CSR storage format is used. To take into account the characteristics of the pressure matrix which turns to be asymmetric for two-phase flow, both single-phase and two-phase calculations were run. In addition, the effect of the matrix size and preconditioning was also investigated. The fine mesh calculation shows better scalability than the coarse mesh because the number of coarse mesh does not need to decompose the computational domain excessively. The fine mesh can be present good scalability when dividing geometry with considering the ratio between computation and communication time. For a given mesh, single-phase flow

Effects of the solar-terrestrial environment on satellite operations

Hot plasma and energetic particle populations in space are known to produce spacecraft operational anomalies. In the inner part of the earth's magnetosphere, these effects are primarily due to durably trapped radiation belt particles, and the integrated doses can be calculated quite accurately for any given orbit. In the outer magnetosphere many spacecraft operational problems appear to be due to intense, transient phenomena. It is shown that three types of naturally-occurring, and highly variable, hostile particle radiation environments are encountered at, or near, the geostationary orbit: (1) high-energy protons due to solar flares; (2) very high energy electrons (2-10 MeV) of unknown origin; and (3) energetic ions and electrons produced by magnetospheric substorms. Present particle sensor systems provide energetic particle detection and assessment capabilities during these kinds of high-energy radiation events. Numerous operational anomalies and subsystem problems have occurred during each type of event period and the association of such upsets is demonstrated in this paper. Methods of prediction of magnetospheric disturbances are discussed, and overall recommendations are made for dealing with this continuing problem

The aim of this study was to assess both psychological distress and personality characteristics associat with primary exercise dependence. A cross-sectional study was carried out with adult habitual physical exercisers. A total of 79 participants voluntarily completed a package of self-report questionnaires including the Exercise Dependence Questionnaire (EDQ), the Eating Disorder Inventory II (EDI-2), the Temperament and Character Inventory (TCI), the Attitude Toward Self scale (ATS), Muscle Dysmorphia Questionnaire (MDQ), and the Symptom Questionnaire (SQ). Significant differences were found in the EDQ exercise for weight control subscale with regard to gender, as well as in the EDI-2 total score and 5 of its subscales, with higher scores for females compared to males. Participants reporting primary exercise dependence (n=32) were more likely to present with disordered eating patterns than controls (n=47). They also showed higher levels of harm avoidance and persistence on the TCI, as well as lower self-directness. Furthermore, primary exercise dependents scored higher on the ATS dysmorphophobia subscale, as well as on the MDQ total score and the anxiety and hostility subscales of the SQ compared to controls. These findings highlight the importance of performing a clinical assessment of psychological symptoms and personality characteristics that might be associated with primary exercise dependence.

This study examined the relationship between certain workgroup characteristics and the experience of abuse in the workplace. Data were collected from 6540 workers at sixteen work sites among six Fortune 500 companies. Workgroup cohesiveness, workgroup interdependence, supervisory concern, supervisory presence and the percent of women in the workgroup were tested for associations with perceived hostility, harassment and negativity for both women and men. Workgroup cohesiveness and supervisory concern showed the strongest protective relationships. The percent of women in the workgroup was also protective for women on all three abuse measures and for men in relation to experienced hostility and negativity. Workgroup interdependence demonstrated an unexpected positive association for experienced hostility and harassment for both men and women. Findings that identify workgroup characteristics that are protective for employees experiencing workplace abuse will be useful for prevention planning.

Challenging Racist Violence and Racist Hostility in 'Post-Racial' Times: Research and Action in Leeds, UK, 2006–2012

Full Text Available Despite increasing understanding of, information about and official commitment to challenge these patterns, racist hostility and violence continue to have an enduring presence in urban and rural life in the UK. This indicates the paradoxical nature of this racial crisis and challenges for antiracism as a political project. This paper charts how these issues play out at the local level through an examination of a five year process from problem identification through to research, response, action and aftermath from 2006 to 2012 in the city of Leeds, UK, with a focus on two predominantly white working class social housing estates in the city. We explore how embedded tensions and antagonisms can begin to be challenged, while examining how the contemporary climate of austerity and cuts in services, together with prevailing post-racial thinking, make the likelihood of such concerted action in the UK increasingly remote.

Hostility among adolescents in Switzerland? multivariate relations between excessive media use and forms of violence.

Science.gov (United States)

Kuntsche, Emmanuel N

2004-03-01

To determine what kind of violence-related behavior or opinion is directly related to excessive media use among adolescents in Switzerland. A national representative sample of 4222 schoolchildren (7th- and 8th-graders; mean age 13.9 years) answered questions on the frequency of television-viewing, electronic game-playing, feeling unsafe at school, bullying others, hitting others, and fighting with others, as part of the Health Behaviour in School-Aged Children (HBSC) international collaborative study protocol. The Chi-square tests and multiple logistic regression analyses were applied to high-risk groups of adolescents. For the total sample, all bivariate relationships between television-viewing/electronic game-playing and each violence-related variable are significant. In the multivariate comparison, physical violence among boys ceases to be significant. For girls, only television-viewing is linked to indirect violence. Against the hypothesis, females' electronic game-playing only had a bearing on hitting others. Experimental designs are needed that take into account gender, different forms of media, and violence to answer the question of whether excessive media use leads to violent behavior. With the exception of excessive electronic game-playing among girls, this study found that electronic media are not thought to lead directly to real-life violence but to hostility and indirect violence.

2017-11-01

Evidence suggests that parenting is associated cross-generationally and that children's genes may elicit specific parenting styles (evocative gene-environment correlation). This study examined whether the effect of children's genotype, specifically 5-HTTLPR, on mothers' parenting behaviors was moderated by her own parenting experiences from her mother. Two independent samples of three-year-olds (N = 476 and 405) were genotyped for the serotonin transporter gene, and observational measures of parenting were collected. Mothers completed measures of the parenting they received as children. The child having a short allele on 5-HTTLPR was associated with more maternal hostility (sample 1 and 2) and with less maternal support (sample 1), but only if the mother reported lower quality grandmothers' parenting (abuse and indifference in Sample 1 and lower levels of grandmother care in Sample 2). Results support the possibility of a moderated evocative gene-environment correlation.

Action-Emotion Style, Learning Approach and Coping Strategies, in Undergraduate University Students

Directory of Open Access Journals (Sweden)

Jesús de la Fuente

Full Text Available Action-Emotion Style (AES is an affective-motivational construct that describes the achievement motivation that is characteristic of students in their interaction with stressful situations. Using elements from the Type-A Behavior Pattern (TABP, characteristics of competitiveness and overwork occur in different combinations with emotions of impatience and hostility, leading to a classification containing five categories of action-emotion style (Type B, Impatient-hostile type, Medium type, Competitive-Overworking type and Type A. The objective of the present research is to establish how characteristics of action-emotion style relate to learning approach (deep and surface approaches and to coping strategies (emotion-focused and problem-focused. The sample was composed of 225 students from the Psychology degree program. Pearson correlation analyses, ANOVAs and MANOVAs were used. Results showed that competitiveness-overwork characteristics have a significant positive association with the deep approach and with problem-focused strategies, while impatience-hostility is thus related to surface approach and emotion-focused strategies. The level of action-emotion style had a significant main effect. The results verified our hypotheses with reference to the relationships between action-emotion style, learning approaches and coping strategies.

The importance of the food and physical activity environments.

There is increasing interest in identifying characteristics of neighborhood environments (physical, social, economical) that might favor unhealthy dietary and physical activity patterns leading to excess weight at population level. Measurement of characteristics of the physical environment in relation to food and physical activity has greatly improved in recent years. Methods based on assessment of perceptions by residents of their neighborhood or on objective assessment of the actual built environment (such as provided by Geographic Information Systems tools) would benefit to be combined. A number of recent systematic reviews have updated our knowledge on relationships of food and physical activity environments with relevant behaviors and obesity. Available evidence appears to show more consistent evidence of association between built environment characteristics related to physical activity ('walkability' indices, land use mix, variety of transports. . .) with physical activity behavior than with weight status. In contrast, built environment characteristics related to food habits (accessibility to different types of food outlets, availability of healthy foods. . .) would be more consistently associated with weight status than with eating behavior. The need for data from different countries and cultures is emphasized, as much as the importance of transdisciplinary research efforts for translation of these findings into our living environment.

The CAVE (TM) automatic virtual environment: Characteristics and applications

Science.gov (United States)

Kenyon, Robert V.

1995-01-01

Virtual reality may best be defined as the wide-field presentation of computer-generated, multi-sensory information that tracks a user in real time. In addition to the more well-known modes of virtual reality -- head-mounted displays and boom-mounted displays -- the Electronic Visualization Laboratory at the University of Illinois at Chicago recently introduced a third mode: a room constructed from large screens on which the graphics are projected on to three walls and the floor. The CAVE is a multi-person, room sized, high resolution, 3D video and audio environment. Graphics are rear projected in stereo onto three walls and the floor, and viewed with stereo glasses. As a viewer wearing a location sensor moves within its display boundaries, the correct perspective and stereo projections of the environment are updated, and the image moves with and surrounds the viewer. The other viewers in the CAVE are like passengers in a bus, along for the ride. 'CAVE,' the name selected for the virtual reality theater, is both a recursive acronym (Cave Automatic Virtual Environment) and a reference to 'The Simile of the Cave' found in Plato's 'Republic,' in which the philosopher explores the ideas of perception, reality, and illusion. Plato used the analogy of a person facing the back of a cave alive with shadows that are his/her only basis for ideas of what real objects are. Rather than having evolved from video games or flight simulation, the CAVE has its motivation rooted in scientific visualization and the SIGGRAPH 92 Showcase effort. The CAVE was designed to be a useful tool for scientific visualization. The Showcase event was an experiment; the Showcase chair and committee advocated an environment for computational scientists to interactively present their research at a major professional conference in a one-to-many format on high-end workstations attached to large projection screens. The CAVE was developed as a 'virtual reality theater' with scientific content and

Fungal melanin: what do we know about structure?

Full Text Available The production of melanin significantly enhances the virulence of many important human pathogenic fungi. Despite fungal melanin’s importance in human disease, as well as melanin’s contribution to the ability of fungi to survive in diverse hostile environments, the structure of melanin remains unsolved. Nevertheless, ongoing research efforts have progressively revealed several notable structural characteristics of this enigmatic pigment, which will be the focus of this review. These compositional and organizational insights could further our ability to develop novel therapeutic approaches to combat fungal disease and enhance our understanding of how melanin is inserted into the cell wall.

Jackson, Debra; Hutchinson, Marie; Peters, Kath; Luck, Lauretta; Saltman, Deborah

2013-04-01

To illuminate ways that avoidant leadership can be enacted in contemporary clinical settings. Avoidance is identified in relation to laissez-faire leadership and passive avoidant leadership. However, the nature and characteristics of avoidance and how it can be enacted in a clinical environment are not detailed. This paper applied secondary analysis to data from two qualitative studies. We have identified three forms of avoidant leader response: placating avoidance, where leaders affirmed concerns but abstained from action; equivocal avoidance, where leaders were ambivalent in their response; and hostile avoidance, where the failure of leaders to address concerns escalated hostility towards the complainant. Through secondary analysis of two existing sets of data, we have shed new light on avoidant leaderships and how it can be enacted in contemporary clinical settings. Further work needs to be undertaken to better understand this leadership style. We recommend that organizations ensure that all nurse leaders are aware of how best to respond to concerns of wrongdoing and that mechanisms are created to ensure timely feedback is provided about the actions taken. © 2012 Blackwell Publishing Ltd.

The roles of competition and power pooling in the utility industry are assessed and explained, and the structure of the Western Electric Utility industry is evaluated. It is argued that a hostile environment for small utilities, maintained by larger investor-owned utilities and by the Bureau of Reclamation, leads to a combination of motives for rapid development of geothermal resources and impedes their success. It is suggested that the impediment feature of the hostile environment for small utilities could be alleviated by granting small utilities access to pooling and, relatedly, by improving the power marketing performance of the Bureau of Reclamation.

2015-09-17

The home food environment can influence the development of dietary behaviours in children, and interventions that modify characteristics of the home food environment have been shown to increase children's fruit and vegetable consumption. However to date, interventions to increase children's fruit and vegetable consumption have generally produced only modest effects. Mediation analysis can help in the design of more efficient and effective interventions by identifying the mechanisms through which interventions have an effect. This study aimed to identify characteristics of the home food environment that mediated immediate and sustained increases in children's fruit and vegetable consumption following the 4-week Healthy Habits telephone-based parent intervention. Analysis was conducted using 2-month (immediate) and 12-month (sustained) follow-up data from a cluster randomised control trial of a home food environment intervention to increase the fruit and vegetable consumption of preschool children. Using recursive path analysis, a series of mediation models were created to investigate the direct and indirect effects of immediate and sustained changes to characteristics of the home food environment (fruit and vegetable availability, accessibility, parent intake, parent providing behaviour, role-modelling, mealtime eating practices, child feeding strategies, and pressure to eat), on the change in children's fruit and vegetable consumption. Of the 394 participants in the randomised trial, 357 and 329 completed the 2- and 12-month follow-up respectively. The final mediation model suggests that the effect of the intervention on the children's fruit and vegetable consumption was mediated by parent fruit and vegetable intake and parent provision of these foods at both 2- and 12-month follow-up. Analysis of data from the Healthy Habits trial suggests that two environmental variables (parental intake and parent providing) mediate the immediate and sustained effect of the

Wayfinding characteristics and familiarity indexes in an urban environment

Full Text Available Many people are encountered with finding the best way to reach to their destination. One definition for wayfinding is “the act of travelling to the destination by continuous processes of making route-choices whilst evaluating previous spatial decisions against stable cognition of the environment.  General understanding and keen appraisal of the environment can aid decision-making process of how to navigate around an area in the form of mental schemas. However, having a level of familiarity and attachment to a place is the underlying factor. The study is aimed at evaluating what is the level of familiarity of people and what is their attachment to notable landmarks in the town of Muar, Malaysia. To do so, the traditional survey analysis with the focus on data set that is attributed to a specific phenomenon and the quantifiable variable using statistical analysis on the tabularized format is undertaken.

Plasmid profiling of bacterial isolates from confined environments

Plasmid profiling of bacterial isolates from confined environments R. Van Houdt, I. Coninx, A. Provoost, N. Leys, and M. Mergeay Expertise group for Molecular and Cellular Biology, Institute for Environment, Health and Safety, Belgian Nuclear Research Centre (SCK•CEN), Boeretang 200, B-2400 Mol, Belgium. Human exploration of extreme and isolated hostile environments such as space requires special confined small volume habitats to protect and house the crew. However, human confinement in such small volume habitats has restrictions on waste disposal and personal hygiene and inevitably generates a particular community of microorganisms within the habitat. These microorganisms are mainly originating from the crew (skin, mucous membranes, upper respiratory tract, mouth, and gastrointestinal tract) but also include the residing environmental microorganisms. Earth-based confined habitats such as the Antarctic Research Station Concordia are used as test beds for long-duration spaceflights to study the physiologic and psychological adaptation to isolated environments. The dynamics of the environmental microbial population in such a test bed could render additional insights in assessing the potential health risks in long-duration space missions. Not only total bacterial contamination levels are important, but it is essential to identify also the predominant microbial taxa and their mobile genetic elements (MGE). These MGEs could be exchanged between bacteria by horizontal gene transfer and may alter the pathogenic potential since they often carry antibiotic resistance or more in general adaptation-enhancing traits. In this study several bacterial strains isolated in the Concordia research station were examined for their plasmid content. An optimized protocol for extraction of large plasmids showed the present of at least one plasmid in 50% of the strains. For all strains the minimal inhibitory concentration of a range of antibiotics was determined indicating resistance to

To study the pattern of dyslipidaemia in patients with stage-V chronic kidney disease on conservative management and those on maintenance haemodialysis. This comparative observational study was conducted at the Jinnah Postgraduate Medical Centre, Karachi, from February to July, 2008, and comprised stage-V chronic kidney disease patients. The patients were divided in two groups. Those who were on conservative management were placed in Group A, and those who were on maintenance haemodialysis were in Group B. Serum total lipid, cholesterol, triglycerides and high-density lipoprotein for both groups were assayed on chemical analyser and low-density lipoprotein was calculated by Friedwald equation. SPSS 17 was used for data analysis. Of the 120 patients, there were 60(50%) in each group. The mean age of patients in Group A was 46.33±14.56 years and in Group B was 43.4±14.1years. Of all, 64(53.3%) were men and 56(46.7%) were women. Mean systolic and diastolic blood pressure was 134±19.58mmHg and 83.6±14.14mmHg in Group A and 129±19.7mmHg and 79.7±12.1mmHg in Group B. Mean serum total lipid was significantly higher (pmaintenance haemodialysis was more hostile than those on conservative management, and posed increased risk of coronary heart disease.

Off-premise alcohol outlet characteristics and violence.

Snowden, Aleksandra J; Pridemore, William Alex

2014-07-01

There is considerable evidence of an association between alcohol outlet density and violence. Although prior research reveals the importance of specific characteristics of bars on this association and that the relationship between bar density and violence may be moderated by these characteristics, there are few similar studies of the characteristics of off-premise outlets (e.g., liquor and convenience stores). We examined whether immediate environment, business practice, staff, and patron characteristics of off-premise alcohol outlets are associated with simple and aggravated assault density. Cross-sectional design using aggregate data from 65 census block groups in a non-metropolitan college town, systematic social observation, and spatial modeling techniques. We found limited effects of immediate environment, business practice, staff, and patron characteristics on simple assault density and no effect on aggravated assault density. Only two out of 17 characteristics were associated with simple assault density (i.e., nearby library and male patrons). This is the first study to examine the association between several off-premise alcohol outlet characteristics and assault. Our findings suggest that where the off-premise outlets are located, how well the immediate environment is maintained, what types of beverages the outlets sell, who visits them, and who works there matter little in their association with violence. This suggests the importance of outlet density itself as a primary driver of any association with violence. Public policies aimed at reducing alcohol outlet density or clustering may be useful for reducing violence.

We determined the phylogenetic position of a heterotrophic nitrifying-aerobic denitrifying bacterium X3, and detected its nitrogen removal characteristics for providing evidence to explain the principle of heterotrophic nitrification-aerobic denitrification and to improve the process in purification of marine-culture wastewater. The evolutionary position of the strain was determined based on its morphological, physiological, biochemical characteristics and 16SrRNA gene sequence. The nitrification-denitrification ability of this strain was detected by detecting its nitrogen removal efficiency and growth on different inorganic nitrogen source. Strain X3 was identified as Halomonas sp. It grew optimally at salinity 3%, pH 8.5, C:N 10:1 at 28 degrees C, and it could still survive at 15% salinity. The removal of NH4+ -N, NO2(-) -N and NO3(-) -N was 98.29%, 99.07%, 96.48% respectively within 24 h. When three inorganic nitrogen existed simultaneously, it always utilized ammonia firstly, and the total inorganic nitrogen removal was higher than with only one nitrogen, suggesting that strain X3 has the ability of simultaneous nitrification and denitrification and completing the whole nitrogen removing process. Strain X3 belonged to the genus of Halomonas. It had strong simultaneous nitrification and denitrification capability and could live in high-salinity environment.

The Effects of Strategic Orientations and Perceived Environment on Firm Performance

Full Text Available Among micro, small, and medium-sized firms located in Hungary, I conducted a survey examining the effects of entrepreneurial and learning orientations, and that of perceived environment on firm performance. I studied the perceptions of environmental turbulence and environmental hostility. Three dimensions were examined both in the case of entrepreneurial orientation (i.e., innovativeness, proactiveness, and risk taking and in the case of learning orientation (i.e., commitment to learning, shared visions, and open-mindedness. The effects of such dimensions on firm performance were analyzed with the path analysis (PLS-SEM method. In the course of the research, firm performance was divided into three dimensions: efficiency, growth, and profit. The possible effect of available financial resources was also taken into consideration. Results show that the availability of financial resources is relatively important, although it is connected only to the growth dimension of performance. Strategic orientations should be interpreted as multi-dimensional, and they have an effect on different performance dimensions. The research was cross-sectional and has implications for long-term strategic decisions.

Fibre optic links operating with multiplexed sensors data are potentially attractive for nuclear power plant applications. It hence became essential to test for radiation vulnerability not only transmission support -fibres- but also fibre-end electro-optical components which could be exposed to hostile environment, perhaps in worse conditions than fibres. Present paper gives results of multimode silica-based fibre behaviour during long-term steady-state low dose-rate gamma ray exposure - one year under 0.1 to 0.2 Gy/h. Studies concerned radiation-induced loss (ΔL) measurement of eight different commercially available fibres and bit error-rate (BER) recording of four 1 100 m length data links operating with a 100 m part exposed to gamma-rays. Main result is the good behaviour of pure silica-core fibres, especially a step-index polymer-clad fibre transmitting 850 nm light but also a graded-index fluorine-clad fibre for 1 300 nm window. Mean ΔL values are respectively 3 dB/km and 4.5 dB/km at the exposure end. Complementary result is no influence of gamma-ray exposure upon data link initial 10 -9 BER.

The relationship between interparental conflict, hostile parenting, and children's externalizing problems is well established. Few studies, however, have examined the pattern of association underlying this constellation of family and child level variables while controlling for the possible confounding presence of passive genotype–environment correlation. Using the attributes of 2 genetically sensitive research designs, the present study examined associations among interparental conflict, parent-to-child hostility, and children's externalizing problems among genetically related and genetically unrelated mother–child and father–child groupings. Analyses were conducted separately by parent gender, thereby allowing examination of the relative role of the mother–child and father–child relationships on children's behavioral outcomes. Path analyses revealed that for both genetically related and genetically unrelated parents and children, indirect associations were apparent from interparental conflict to child externalizing problems through mother-to-child and father-to-child hostility. Associations between interparental conflict and parent-to-child hostility across genetically related and genetically unrelated parent–child groupings were significantly stronger for fathers compared to mothers. Results are discussed with respect to the role of passive genotype–environment correlation as a possible confounding influence in interpreting research findings from previous studies conducted in this area. Implications for intervention programs focusing on family process influences on child externalizing problems are also considered. PMID:23421830

In Thailand, red light running is considered as one of the most dangerous behaviors at intersection. Red light running (RLR) behavior is the failure to obey the traffic control signal. However, motorcycle riders and car drivers who are running through red lights could be influenced by human factors or road environment at intersection. RLR could be advertent or inadvertent behavior influenced by many factors. Little research study has been done to evaluate the contributing factors influencing the red-light violation behavior. This study aims to determine the factors influencing the red light running behavior including human characteristics, physical condition of intersection, traffic signal operation, and traffic condition. A total of 92 intersections were observed in Chiang Mai, Nakhon Ratchasima, and Chonburi, the major provinces in each region of Thailand. In addition, the socio-economic characteristics of red light runners were obtained from self-reported questionnaire survey. The Binary Logistic Regression and the Multiple Linear Regression models were used to determine the characteristics of red light runners and the factors influencing rates of red light running respectively. The results from this study can help to understand the characteristics of red light runners and factors affecting them to run red lights. For motorcycle riders and car drivers, age, gender, occupation, driving license, helmet/seatbelt use, and the probability to be penalized when running the red light significantly affect RLR behavior. In addition, the results indicated that vehicle travelling direction, time of day, existence of turning lane, number of lanes, lane width, intersection sight distance, type of traffic signal pole, type of traffic signal operation, length of yellow time interval, approaching speed, distance from intersection warning sign to stop line, and pavement roughness significantly affect RLR rates.

To determine which, if any, characteristics should be incorporated into a select-in approach to screening personnel for long-duration spaceflight, we examined the influence of crewmember social/ demographic characteristics, personality traits, interpersonal needs, and characteristics of station physical environments on performance measures in 657 American men who spent an austral winter in Antarctica between 1963 and 1974. During screening, subjects completed a Personal History Questionnaire which obtained information on social and demographic characteristics, the Deep Freeze Opinion Survey which assessed 5 different personality traits, and the Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B) Scale which measured 6 dimensions of interpersonal needs. Station environment included measures of crew size and severity of physical environment. Performance was assessed on the basis of combined peer-supervisor evaluations of overall performance, peer nominations of fellow crewmembers who made ideal winter-over candidates, and self-reported depressive symptoms. Social/demographic characteristics, personality traits, interpersonal needs, and characteristics of station environments collectively accounted for 9-17% of the variance in performance measures. The following characteristics were significant independent predictors of more than one performance measure: military service, low levels of neuroticism, extraversion and conscientiousness, and a low desire for affection from others. These results represent an important first step in the development of select-in criteria for personnel on long-duration missions in space and other extreme environments. These criteria must take into consideration the characteristics of the environment and the limitations they place on meeting needs for interpersonal relations and task performance, as well as the characteristics of the individuals and groups who live and work in these environments.

Hypoxia Inducible Factor-1α (HIF-1 α and its Role in Tumour Progression to Malignancy

Directory of Open Access Journals (Sweden)

Full Text Available Hypoxia is a condition in which an area of the body or a tissue is deprived of sufficient supply of oxygen. The lack of nutrients in a hypoxic tissue generally causes apoptosis but some cells are able to adapt to this hypoxic environment and resist apoptosis. This adaptation occurs as a result of gene activation. Hypoxia is a characteristic feature of many cancers and is the stimulus for overexpression of HIF-1α - a basic loop-helix PAS protein family subunit of HIF, which allows the cell to adapt and survive in hostile environment. The presence of hypoxia and HIF-1α is correlated with an increased risk of metastasis and techniques that can inhibit hypoxia inducible factor may be instrumental in finding a cure for cancer.

This research tests the possibility that the reasonable woman as compared to the reasonable person test of hostile work environment sexual harassment interacts with hostile and benevolent sexist beliefs and under some conditions triggers protectionist attitudes toward women who complain of sexual harassment. We administered to a sample of undergraduates the ambivalent sexism inventory along with the fact patterns in two harassment cases and asked them to make legally relevant decisions under either the reasonable woman or person standard. We found that those high in hostile sexism, and women, found more evidence of harassment. However, those high in benevolent sexism did not exhibit the hostile sexism effects. Although men were less sensitive to the reasonable woman standard than women, under some conditions the reasonable woman standard enabled both genders to find greater evidence of harassment. The results are discussed from the perspectives of law and psychology.

The proposed Fusion Engineering Research Facility (FERF) has been designed for the test and evaluation of materials that will be exposed to the hostile radiation environment created by fusion reactors. Because the FERF itself must create a very hostile radiation environment, extensive remote handling procedures will be required as part of its routine operations as well as for both scheduled and unscheduled maintenance. This report analyzes the remote-handling implications of a vertical- rather than horizontal-orientation of the FERF magnet, describes the specific remote-handling facilities of the proposed FERF installation and compares the FERF remote-handling system with several other existing and proposed facilities.

Despite reports that there has been a positive trend in perception and treatment of lesbian, gay, and bisexual (LGB) individuals in recent years (Griffin, 2012 ; Loftus, 2001 ), sport, in general, is still an uncertain, and sometimes even hostile, environment for LGB athletes (Anderson, 2005 ; Waldron & Krane, 2005 ). To gain more information on coach understanding and perceptions of the team environment, 10 high school head coaches in the United States were interviewed to explore their experiences coaching openly LGB athletes. Qualitative analyses revealed four primary themes associated with coach experiences: team environment dogmas and observations, fundamental beliefs contributing to perceptions of LGB athletes, types and timing of sexual orientation disclosure, and differential LGB athlete characteristics. Future research should examine these primary themes in more detail through interviews with LGB athletes, as well as high school coaches in more traditionally masculine sports, such as football, men's basketball, and wrestling.

Based on the scientific and technological achievements in the past decade in the Loess Hilly-gully Region and the successful demonstration experience in Yan’an Yangou watershed, we summarize the characteristics of eco-environment restoration pattern based on "building terrace and returning slope farmland to forests and grass". According to the data on land use, slope farmland and the agricultural population in 1999, we calculate the area of new terrace that needs to be built, the area of garden plot that needs to be extended, vegetation restoration area and investment demand in counties (cities, districts). Establishing and using some indicators, such as basic farmland extension indicator, garden plot extension indicator, vegetation restoration index and investment demand density, we conduct type classification and analysis of regional differentiation characteristics in 55 counties (cities, districts). The results show that in the Loess Hilly-gully Region, 691 600 hm2 of new terrace needs to be built, 792 000 hm2 of economic forests and orchards need to be extended, 5 410 200 hm2 of vegetation needs to be restored, and the total investment demand is 15.82 billion yuan; in terms of geographical distribution, obviously there are two key areas for eco-environment restoration (one is located in the border area between northern Shaanxi and northwestern Shanxi, and the other is located in the eastern Gansu and southern Ningxia area); the classified regional guidance policies should be formulated as soon as possible, and the limited funds should be concentrated in the key areas.

In several European countries, the availability of qualified nurses is insufficient to meet current healthcare requirements. Nurses are highly dissatisfied with the rising demands of the healthcare environment and increasingly considering leaving their jobs. The study aims to investigate the relationships between the characteristics of hospital nurses' work environment and the quality of care provided, and furthermore to examine Dutch nurses' career plans. A cross-sectional, questionnaire survey of registered nurses (n = 334) working in the academic and district hospitals was conducted in 2005/2006. Previously validated questionnaires translated into the participants' language were used. Factor and regression analysis were used for data analysis. Overall, nurses rated their work environment rather favourably. Five work environment characteristics were identified: support for professional development, adequate staffing, nursing competence, supportive management and teamwork. Significant relationships were found between nurses' perceptions of their work environment characteristics and quality of care provided and nurses' career plans. When work environment characteristics were evaluated to be better, nurse-assessed quality of care also increased and intentions to leave current job decreased linearly. Study findings suggest that nurses' perceptions of their work environment are important for nurse outcomes in hospital settings. Further research is needed to explore the predictive ability of the work environment for nurse, patient and organizational outcomes in hospitals. © 2011 The Authors.

To investigate the impact of nurse practice environment factors, nurse work characteristics, and burnout on nurse reported job outcomes, quality of care, and patient adverse events variables at the nursing unit level. Nurse practice environment studies show growing insights and knowledge about determining factors for nurse workforce stability, quality of care, and patient safety. Until now, international studies have primarily focused on variability at the hospital level; however, insights at the nursing unit level can reveal key factors in the nurse practice environment. A cross-sectional design with a survey. In a cross-sectional survey, a sample of 1108 nurses assigned to 96 nursing units completed a structured questionnaire composed of various validated instruments measuring nurse practice environment factors, nurse work characteristics, burnout, nurse reported job outcomes, quality of care, and patient adverse events. Associations between the variables were examined using multilevel modelling techniques. Various unit-level associations (simple models) were identified between nurse practice environment factors, nurse work characteristics, burnout dimensions, and nurse reported outcome variables. Multiple multilevel models showed various independent variables such as nursing management at the unit level, social capital, emotional exhaustion, and depersonalization as important predictors of nurse reported outcome variables such job satisfaction, turnover intentions, quality of care (at the unit, the last shift, and in the hospital within the last year), patient and family complaints, patient and family verbal abuse, patient falls, nosocomial infections, and medications errors. Results suggested a stable nurse work force, with the capability to achieve superior quality and patient safety outcomes, is associated with unit-level favourable perceptions of nurse work environment factors, workload, decision latitude, and social capital, as well low levels of burnout

Stan, Marius

2000-01-01

The golden dream of any modeling enterprise is to predict the properties of the studied system in a new and often 'hostile' environment. The basis of this kind of work is the careful, accurate assessment of the system properties in normal conditions. What 'normal conditions' means for plutonium is an interesting question itself. This work is dedicated to modeling only a fraction of the remarkable characteristics of this 'mysterious' material, that is the thermodynamic properties of its six allotropic phases (seven under pressure), the liquid phase, and the vapor phase. The goal is to provide valuable information for the calculation of alloyed plutonium phase diagrams

The current study examined the main effects of hostile attributional bias (HAB) and negative emotional responding on a variety of aggressive behaviors in adults, including general aggression, physical aggression, relational aggression, and verbal aggression. Effects of both externalizing (anger) and internalizing (embarrassment/upset) negative emotions were considered. In addition, the moderating roles of gender and impulsivity on the effects of HAB and negative emotional responding were explored. Multilevel models were fitted to data from 2,749 adult twins aged 20-55 from the PennTwins cohort. HAB was positively associated with all four forms of aggression. There was also a significant interaction between impulsivity and HAB for general aggression. Specifically, the relationship between HAB and general aggression was only significant for individuals with average or above-average levels of impulsivity. Negative emotional responding was also found to predict all measures of aggression, although in different ways. Anger was positively associated with all forms of aggression, whereas embarrassment/upset predicted decreased levels of general, physical, and verbal aggression but increased levels of relational aggression. The associations between negative emotional responding and aggression were generally stronger for males than females. The current study provides evidence for the utility of HAB and negative emotional responding as predictors of adult aggression and further suggests that gender and impulsivity may moderate their links with aggression. © 2011 Wiley Periodicals, Inc.

Parenting style and parental support and modeling of physical activity and healthy dietary intake have been linked to youth weight status, although findings have been inconsistent across studies. Furthermore, little is known about how these factors co-occur, and the influence of the coexistence of these factors on adolescents' weight. This article examines the relationship between the co-occurrence of various parenting characteristics and adolescents' weight status. Data are from Project EAT (eating among teens), a population-based study of 4,746 diverse adolescents. Theoretical and latent class groupings of parenting styles and parenting practices were created. Regression analyses examined the relationship between the created variables and adolescents' BMI. Having an authoritarian mother was associated with higher BMI in sons. The co-occurrence of an authoritarian mother and neglectful father was associated with higher BMI for sons. Daughters' whose fathers did not model or encourage healthy behaviors reported higher BMIs. The co-occurrence of neither parent modeling healthy behaviors was associated with higher BMIs for sons, and incongruent parental modeling and encouraging of healthy behaviors was associated with higher BMIs in daughters. Although, further research into the complex dynamics of the home environment is needed, findings indicate that authoritarian parenting style is associated with higher adolescent weight status and incongruent parenting styles and practices between mothers and fathers are associated with higher adolescent weight status.

Full Text Available Home environment and family lifestyle practices have an influence on child obesity risk, thereby making it critical to systematically examine these factors. Thus, parents (n = 489 of preschool children completed a cross-sectional online survey which was the baseline data collection conducted, before randomization, in the HomeStyles program. The survey comprehensively assessed these factors using a socio-ecological approach, incorporating intrapersonal, interpersonal and environmental measures. Healthy intrapersonal dietary behaviors identified were parent and child intakes of recommended amounts of 100% juice and low intakes of sugar-sweetened beverages. Unhealthy behaviors included low milk intake and high parent fat intake. The home environment’s food supply was found to support healthy intakes of 100% juice and sugar-sweetened beverages, but provided too little milk and ample quantities of salty/fatty snacks. Physical activity levels, sedentary activity and the home’s physical activity and media environment were found to be less than ideal. Environmental supports for active play inside homes were moderate and somewhat better in the area immediately outside homes and in the neighborhood. Family interpersonal interaction measures revealed several positive behaviors, including frequent family meals. Parents had considerable self-efficacy in their ability to perform food- and physical activity-related childhood obesity protective practices. This study identified lifestyle practices and home environment characteristics that health educators could target to help parents promote optimal child development and lower their children’s risk for obesity.

There is some evidence that maternal borderline personality disorder (BPD) adversely affects parenting in infancy, resulting in disorganized attachment, which longitudinally predicts BPD symptoms in adulthood. We examined parenting related to disorganized attachment beyond infancy in offspring of mothers with BPD, when parenting becomes a goal-corrected partnership. We observed puzzle solving in a low socioeconomic status (SES) sample of mothers with BPD and their children ages 4-7, n = 36, and normative comparisons, n = 34. Compared with normative mothers and controlling for maternal mood disorders, mothers with BPD were less likely to be sensitive and provide autonomy support, and were more likely to be hostile and display fearful/disoriented behavior and higher levels of parent-child role reversal. We additionally found correlations between parenting and self-reported maternal borderline features. We discuss implications for child development, including possible transmission of BPD from mothers to children via representational models, and developmentally appropriate preventive interventions.

Chlorite is genetically related to uranium mineralization in Huangnihu uranium deposit. By means of microscopic and electronic microprobe analysis, the authors investigated chemical composition and texture of the chlorite and found that chlorite in Huangnihu deposit has the following characteristics: 1. they are mainly Fe-rich chlorite composed of chamosite and brunsvigite, of which chemical composition is mainly affected by mud and mafic rock; 2. the Fe-Mg and Al"I"V-Si substitution dominates the octahedral substitution supplemented by Al"V"I-Fe substitution; the oolitic chlorite and biotite feinted chlorite closely associated with uranium were formed at temperatures of 216.23 ∼ 256.73℃ (average 228.6℃). The chemical composition and forming environment of the oolitic chlorite and biotite illusion chlorite suggests that Huangnihu uranium deposit is a low-moderate temperature hydrothermal uranium deposit formed in a reducing environment and iron-rich formation, the ore-forming fluid mainly originated from shale rock, partly from ultramafic or mafic liquid.

In order to explore the adsorption characteristics of proteins on the membrane surface and the effect of protein solution environment on the permeation behavior of berberine, berberine and proteins were used as the research object to prepare simulated solution. Low field NMR, static adsorption experiment and membrane separation experiment were used to study the interaction between the proteins and ceramic membrane or between the proteins and berberine. The static adsorption capacity of proteins, membrane relative flux, rejection rate of proteins, transmittance rate of berberine and the adsorption rate of proteins and berberine were used as the evaluation index. Meanwhile, the membrane resistance distribution, the particle size distribution and the scanning electron microscope (SEM) were determined to investigate the adsorption characteristics of proteins on ceramic membrane and the effect on membrane separation process of berberine. The results showed that the ceramic membrane could adsorb the proteins and the adsorption model was consistent with Langmuir adsorption model. In simulating the membrane separation process, proteins were the main factor to cause membrane fouling. However, when the concentration of proteins was 1 g•L⁻¹, the proteins had no significant effect on membrane separation process of berberine. Copyright© by the Chinese Pharmaceutical Association.

Deep-sea carbon dioxide (CO 2 ) plays a significant role in the global carbon cycle and directly affects the living environment of marine organisms. In situ Raman detection technology is an effective approach to study the behavior of deep-sea CO 2 . However, the Raman spectral characteristics of CO 2 can be affected by the environment, thus restricting the phase identification and quantitative analysis of CO 2 . In order to study the Raman spectral characteristics of CO 2 in extreme environments (up to 300 ℃ and 30 MPa), which cover most regions of hydrothermal vents and cold seeps around the world, a deep-sea extreme environment simulator was developed. The Raman spectra of CO 2 in different phases were obtained with Raman insertion probe (RiP) system, which was also used in in situ Raman detection in the deep sea carried by remotely operated vehicle (ROV) "Faxian". The Raman frequency shifts and bandwidths of gaseous, liquid, solid, and supercritical CO 2 and the CO 2 -H 2 O system were determined with the simulator. In our experiments (0-300 ℃ and 0-30 MPa), the peak positions of the symmetric stretching modes of gaseous CO 2, liquid CO 2 , and supercritical CO 2 shift approximately 0.6 cm -1 (1387.8-1388.4 cm -1 ), 0.7 cm -1 (1385.5-1386.2 cm -1 ), and 2.5 cm -1 (1385.7-1388.2 cm -1 ), and those of the bending modes shift about 1.0 cm -1 (1284.7-1285.7 cm -1 ), 1.9 cm -1 (1280.1-1282.0 cm -1 ), and 4.4 cm -1 (1281.0-1285.4 cm -1 ), respectively. The Raman spectral characteristics of the CO 2 -H 2 O system were also studied under the same conditions. The peak positions of dissolved CO 2 varied approximately 4.5 cm -1 (1282.5-1287.0 cm -1 ) and 2.4 cm -1 (1274.4-1276.8 cm -1 ) for each peak. In comparison with our experiment results, the phases of CO 2 in extreme conditions (0-3000 m and 0-300 ℃) can be identified with the Raman spectra collected in situ. This qualitative research on CO 2 can also support the

The object of this study is to investigate sociodemographic and clinical characteristics, psychology, self-esteem and quality of life in cancer patients on radiation therapy and to provide useful information for therapeutic approach to cancer patients on radiation therapy. The subjects were 36 patients who had been treated with radiation therapy and 20 normal people. Sociodemographic information and clinical characteristics of cancer patients on radiation therapy were investigated, and symptom checklist-90-revised, Rosenberg Self-esteem Scale for self esteem, World Health Organization Quality of Life Assessment Instrument for quality of life were administered to subjects. And Spearman's correlation analysis was used among these. The tendency of somatization, depression, anxiety and hostility in cancer group were significantly higher than normal group. Self esteem and quality of life in cancer group were significantly lower than normal group. No significant difference was found in comparison of psychology, self esteem and quality of life according to sociodemographic variables. Among clinical characteristics, in the presence of metastasis in cancer patients, the scores of anxiety, phobia and paranoid ideation were higher. In patients with pain, the score of somatization was higher. And in case of weight loss, the score of somatization was higher. The higher score of depression, anxiety and hostility were significantly associated with lower self-esteem. And higher score of somatization, depression, anxiety and hostility were significantly associated with lower quality of life. Understanding and management of psychological symptoms, such as somatization, depression, anxiety, and hostility, and pain control are necessary to improve quality of life in cancer patients on radiation therapy.

The object of this study is to investigate sociodemographic and clinical characteristics, psychology, self-esteem and quality of life in cancer patients on radiation therapy and to provide useful information for therapeutic approach to cancer patients on radiation therapy. The subjects were 36 patients who had been treated with radiation therapy and 20 normal people. Sociodemographic information and clinical characteristics of cancer patients on radiation therapy were investigated, and symptom checklist-90-revised, Rosenberg Self-esteem Scale for self esteem, World Health Organization Quality of Life Assessment Instrument for quality of life were administered to subjects. And Spearman's correlation analysis was used among these. The tendency of somatization, depression, anxiety and hostility in cancer group were significantly higher than normal group. Self esteem and quality of life in cancer group were significantly lower than normal group. No significant difference was found in comparison of psychology, self esteem and quality of life according to sociodemographic variables. Among clinical characteristics, in the presence of metastasis in cancer patients, the scores of anxiety, phobia and paranoid ideation were higher. In patients with pain, the score of somatization was higher. And in case of weight loss, the score of somatization was higher. The higher score of depression, anxiety and hostility were significantly associated with lower self-esteem. And higher score of somatization, depression, anxiety and hostility were significantly associated with lower quality of life. Understanding and management of psychological symptoms, such as somatization, depression, anxiety, and hostility, and pain control are necessary to improve quality of life in cancer patients on radiation therapy

Biological agents are unique class of microorganisms which can be used to produce the disease in large populations of humans, animals and plants. If used for hostile purposes, any disease-causing microorganism could be considered a weapon. The use of biological agents is not a new concept and history is replete with examples of biological weapon use. Before the twenty century, biological warfare took on three main forms by deliberate poisoning of food and water with infectious material, use of microorganisms or toxins in some form of weapon system, and use of biologically inoculated fabrics. Four kinds of biological warfare agents are bacteria, viruses, rickettsiae, fungi. These are distinguished by being living organisms, that reproduce within their host victims, who then become contagious with a deadly multiplier effect, bacteria, viruses, or fungi or toxin found in nature can be used to kill or injure people. Biological agents may be used for an isolated assassination, as well as to cause incapacitation or death to thousands. These biological agents represent a dangerous military threat because they are alive, and are therefore unpredictable and uncontrollable once released. The act of bioterrorism can range from a simple hoax to the actual use of biological weapons. Biological agents have the potential to make an environment more dangerous over time. If the environment is contaminated, a long-term threat to the population could be created. This paper discusses common biological agents, their mode of action in living organisms and possible impact on the environment. (author)

Occult intraocular trauma: evaluation of the eye in an austere environment.

Physicians deployed to austere environments often encounter the challenge of needing to make clinical decisions based upon rudimentary history and physical examination. These skills, however, can be difficult for many to rely on, with the many subtleties of examining the eye, when they are normally accustomed to relying on sophisticated modalities to establish diagnosis. This case is a model for evaluating eye trauma in an austere or hostile environment. A 25-year-old male U.S. Marine was fired upon at a Mexican Army checkpoint where he sustained glass shrapnel injuries, the most serious being to his right eye. He was taken from a detention facility to a Mexican hospital, where he was evaluated and given the diagnosis of corneal laceration. Twelve hours later, a U.S. Navy physician arrived to evaluate the patient; he was allowed limited access to the patient. His ophthalmologic examination revealed a closed corneal laceration on the right eye, worse than 20/800 vision, absent red reflex, and obscured funduscopic examination. These findings made it impossible to rule out globe penetration. The patient was released 48 h later to a U.S. Naval Hospital, where intraocular foreign bodies were confirmed by imaging and he was taken to emergency surgery. This case illustrates that even under austere conditions, a focused history and evaluation can reveal the likelihood of occult intraocular foreign body, thereby triaging the patient for emergency surgery.

Drawing on the person-environment (P-E) fit perspective, this study examined the role of environment on the well-being of vulnerable older adults in a non-western context. Using the indicators from the World Health Organization's (WHO) framework for age friendly cities (ACF), we examined life satisfaction among South Korean older adults, exploring the extent to which multidimensional environmental characteristics are associated with low socioeconomic status (SES). Using the regionally representative data from the Seoul City-wide needs assessment of middle- and old-aged adults, an analytic sample (N = 1657) focused on community-living individuals aged 65 and older. Multilevel regression models examined interaction between SES subgroups and varying aspects of the environment (i.e. physical, social, and service environment) as related to life satisfaction. Consistent with the environmental docility hypothesis, members of the most vulnerable subgroup in the Korean context - older adults who are living alone and poor - are more likely to have higher life satisfaction when they have higher levels of support in physical and social environments. Interestingly, a higher level of support in the service environment was related to lower life satisfaction for this subgroup. This study provides an empirical foundation for efforts to identify age-friendly environmental characteristics as modifiable environmental resources that can improve older adults' psychological well-being. As the first attempt to use WHO ACF indicators within the P-E fit perspective in a non-Western context, our study provides a foundation for designing support services or programs that effectively meet the needs of vulnerable older adults.
