    To better understand individual differences in sensation seeking and its components, including boredom susceptibility and experience seeking, we examined brain responses of high and low sensation seekers during repeated visual experience. Individuals scoring in the top and bottom quartiles from a college-aged population on the Brief Sensation-Seeking Scale (BSSS) participated in an event-related potentials (ERPs) experiment. Line drawings of common objects were randomly intermixed and present...

    High sensation seeking is associated with strong approach behaviors and weak avoidance responses. The present study used functional magnetic resonance imaging (fMRI) to further characterize the neurobiological underpinnings of this behavioral profile using a Go/No-go task. Analysis of brain activation associated with response inhibition (No-go) versus response initiation and execution (Go) revealed the commonly reported right lateral prefrontal, insula, cingulate, and supplementary motor area network. However, right lateral activation was associated with greater No-go than Go responses only in low sensation seekers. High sensation seekers showed no differential activation in these regions but a more pronounced Go compared to No-go response in several other regions that are involved in salience detection (insula), motor initiation (anterior cingulate) and attention (inferior parietal cortex). Temporal analysis of the hemodynamic response for Go and No-go conditions revealed that the stronger response to Go than No-go trials in high sensation seekers occurred in in the earliest time window in the right middle frontal gyrus, right mid-cingulate and right precuneus. In contrast, the greater No-go than Go response in low sensation seekers occurred in the later time window in these same regions. These findings indicate that high sensation seekers more strongly attend to or process Go trials and show delayed or minimal inhibitory responses on No-go trials in regions that low sensation seekers use for response inhibition. Failure to engage such regions for response inhibition may underlie some of the risky and impulsive behaviors observed in high sensation seekers. Copyright © 2012 Elsevier B.V. All rights reserved.

    Previous studies have indicated that high sensation seekers are more sensitive to the reinforcing effects of nicotine, initiate smoking at an earlier age, and smoke greater amounts of cigarettes. This study examined the influence of sensation-seeking status on tobacco smoking following deprivation in regular tobacco users. Twenty healthy tobacco-smoking volunteers with low or high impulsive sensation-seeking subscale scores completed 2 consecutive test days per week for 3 consecutive weeks. Each week, a range of self-report, performance, and cardiovascular assessments were completed during ad libitum smoking on Day 1 and before and after the paced smoking of a tobacco cigarette containing 0.05, 0.6, or 0.9 mg of nicotine following 24 hr of tobacco deprivation on Day 2. In addition, self-administration behavior was analyzed during a 2-hr free access period after the initial tobacco administration. In high sensation seekers, tobacco smoking independent of nicotine yield ameliorated deprivation effects, whereas amelioration of deprivation effects was dependent on nicotine yield among low sensation seekers. However, this effect was limited to a small subset of measures. Subsequent cigarette self-administration increased in a nicotine-dependent manner for high sensation seekers only. Compared with low sensation seekers, high sensation seekers were more sensitive to the withdrawal relieving effects of nonnicotine components of smoking following 24 hr of deprivation on selective measures and more sensitive to nicotine yield during subsequent tobacco self-administration. These results are consistent with studies suggesting that factors driving tobacco dependence may vary as a function of sensation-seeking status.

  7. Sensation seekers as a healthcare marketing metasegment.

    Science.gov (United States)

    Self, Donald R; Findley, Carolyn Sara

    2010-01-01

    This article discusses "sensation seekers" as a market segment for communication and prevention programs for various lifestyle and/or risk-related health problem areas such as alcohol abuse, drug abuse, suicide attempts, and sexually transmitted diseases. Although sensation seekers tend to be creative, artistic individuals, they are also prone to various negative health behaviors and many population-based prevention programs have over-looked these individuals as an important target. Various inputs to sensation-seeking causation are explored, including biological/chemical, psychological, and the impact of external characteristics. Using a combination for regulatory focus and risk homeostasis, propositions are provided for improving the effectiveness of the communications. Recommendations for prevention efforts focusing on reaching this subculture using television, along with other electronic media are proposed, including recommendations for message construction and presentation venues.

  8. Are online poker problem gamblers sensation seekers?

    Bonnaire, Céline

    2018-03-31

    The purpose of this research was to examine the relationship between sensation seeking and online poker gambling in a community sample of adult online poker players, when controlling for age, gender, anxiety and depression. In total, 288 online poker gamblers were recruited. Sociodemographic data, gambling behavior (CPGI), sensation seeking (SSS), depression and anxiety (HADS) were evaluated. Problem online poker gamblers have higher sensation seeking scores (total, thrill and adventure, disinhibition and boredom susceptibility subscores) and depression scores than non-problem online poker gamblers. Being male, with total sensation seeking, disinhibition and depression scores are factors associated with online poker problem gambling. These findings are interesting in terms of harm reduction. For example, because disinhibition could lead to increased time and money spent, protective behavioral strategies like setting time and monetary limits should be encouraged in poker online gamblers.

    2011-01-01

    High sensation seekers (HSS) prefer messages that allow them to maintain an optimal level of arousal (i.e., highly arousing messages). Transportation theory suggests that narrative immersion in a story may moderate reader arousal, and thus HSS message selection. To test this idea, a survey was administered to 120 fourth and fifth graders. In…

  10. Designing messages with high sensation value: when activation meets reactance.

    Science.gov (United States)

    Xu, Jie

    2015-01-01

    Based on two theoretical models--activation model of information exposure and psychological reactance theory--this study examined the individual and combined effects of message sensation value (MSV) and controlling language on young adults' information processing. Two experimental studies on anti-drunken driving and anti-smoking public service announcements were conducted that were conceptual replications of one another. The measures included perceived threat to freedom, sensation seeking, perceived ad effectiveness and state reactance (anger). Across the two studies, MSV was found to advance the perceived ad effectiveness, and controlling language contributed to anger. A consistent interaction was revealed, such that participants responded positively to the high sensation value messages when presented with low controlling language. The effect of high sensation value anti-smoking ads to advance persuasiveness particularly under the condition of low controlling language was more influential to low sensation seekers. This study suggests that increasing MSV coupled with high controlling language can backfire, especially when targeting young adults. The implications for persuasion in general are considered, as well as the specific findings for drunken driving and smoking.

    Lee, Moon J; Shin, Mija

    2011-01-01

    This study investigates the differences in physiological, cognitive, and emotional responses to existing emotional antialcohol abuse advertisements (fear vs. humor appeal) between high and low sensation seekers. A 2 (Message Type) x 2 (Sensation-Seeking Tendency) x 4 (Message Repetition) mixed-model experiment with repeated measures was conducted with 71 college students. The results, based on self-reports, indicated that fear messages generated more interest and perceived danger of excessive drinking regardless of sensation-seeking tendency, whereas humorous messages were rated as more likeable than fear messages, and the difference was bigger among low sensation seekers than among high sensation seekers. One interesting finding was that for both fear and humor appeals, low sensation seekers showed greater emotional responses (greater corrugators activities and greater zygomatic activities) than high sensation seekers overall. The implications of the current study as well as suggestions for future study were discussed.

    2014-09-01

    Sensation seeking is defined by a strong need for varied, novel, complex, and intense stimulation, and a willingness to take risks for such experience. Several theories propose that the insensitivity to negative consequences incurred by risks is one of the hallmarks of sensation-seeking behaviors. In this study, we investigated the time course of error processing in sensation seeking by recording event-related potentials (ERPs) while high and low sensation seekers performed an Eriksen flanker task. Whereas there were no group differences in ERPs to correct trials, sensation seeking was associated with a blunted error-related negativity (ERN), which was female-specific. Further, different subdimensions of sensation seeking were related to ERN amplitude differently. These findings indicate that the relationship between sensation seeking and error processing is sex-specific. Copyright © 2014 Society for Psychophysiological Research.

  15. Message sensation and cognition values: factors of competition or integration?

    Science.gov (United States)

    Xu, Jie

    2015-01-01

    Using the Activation Model of Information Exposure and Elaboration Likelihood Model as theoretical frameworks, this study explored the effects of message sensation value (MSV) and message cognition value (MCV) of antismoking public service announcements (PSAs) on ad processing and evaluation among young adults, and the difference between high sensation seekers and low sensation seekers in their perceptions and responses toward ads with different levels of sensation and cognition value. A 2 (MSV: high vs. low) × 2 (MCV: high vs. low) × 2 (need for sensation: high vs. low) mixed experimental design was conducted. Two physiological measures including skin conductance and heart rate were examined. Findings of this study show that MSV was not a distraction but a facilitator of message persuasiveness. These findings contribute to the activation model. In addition, need for sensation moderated the interaction effect of MSV and MCV on ad processing. Low sensation seekers were more likely to experience the interaction between MSV and MCV than high sensation seekers. Several observations related to the findings and implications for antismoking message designs are elaborated. Limitations and directions for future research are also outlined.

    Full Text Available The study examined sensation seeking intensity level in males involved in recreational high risk sports and investigated whether its level depends on type of sport practised. Additionally, in case of parachutists, sport experience of study participants were scrutinised with regard to its possible impact on the level of sensation seeking.The research involved 217 males aged 17 to 45, practising recreational high risk sports, namely: parachuting (n=98; wakeboarding (n=30; snowboarding (n=30; scuba diving (n=22; alpinism (n=20; paragliding (n=17. The control group included 54 men not involved in sports. Polish version of Sensation Seeking Scale (SSS-IV of Zuckerman was applied.Results show, that high risk sports males are featured by stronger need of sensations in comparison to control group and this concerned all but one aspect of sensation seeking variable. The only exception was the need of intellectual stimulation. Except from the thrill and adventure seeking dimension, type of sport may also be an important determinant of sensation seeking. Men practising snowboard and wakeboard presented stronger need for sensations, especially in the dimension of experience seeking, disinhibition and boredom susceptibility. Sport experience (number of jumps in parachuting did not differentiate the level of sensation seeking among investigated parachutists. Population of sport high risk male takers was not homogeneous, and therefore in future research one should analyse specific sports (or events in a certain sport separately.

  19. Sensation seeking and alcohol use by college students: examining multiple pathways of effects.

    2006-01-01

    This study tests the proposition that peer influence mediates the effect of sensation seeking, a personality trait, on alcohol use among college students. Cross-sectional data to test this proposition were collected from a representative sample of college students at a large public northeastern university (N = 427). Results of hierarchical regression analyses showed that, as hypothesized, sensation seeking influenced personal alcohol use both directly and indirectly, through its impact on students' frequency of association with alcohol-using peers and the size of their drinking norm misperception. The findings suggest that interventions that seek to limit the frequency in which high sensation seekers associate with peers whose alcohol use is extreme or, alternatively, seek to facilitate social interactions of high sensation seekers with normative peers, may supplement efforts to influence sensation seekers' alcohol and other drug use through tailored mass media advertisements.

    Novel images and message content enhance visual attention and memory for high sensation seekers, but the neural mechanisms associated with this effect are unclear. To investigate the individual differences in brain responses to new and old (studied) visual stimuli, we utilized event-related potentials (ERP) and functional Magnetic Resonance Imaging (fMRI) measures to examine brain reactivity among high and low sensation seekers during a classic old-new memory recognition task. Twenty low and 20 high sensation seekers completed separate, but parallel, ERP and fMRI sessions. For each session, participants initially studied drawings of common images, and then performed an old-new recognition task during scanning. High sensation seekers showed greater ERP responses to new objects at the frontal N2 ERP component, compared to low sensation seekers. The ERP Novelty-N2 responses were correlated with fMRI responses in the orbitofrontal gyrus. Sensation seeking status also modulated the FN400 ERP component indexing familiarity and conceptual learning, along with fMRI responses in the caudate nucleus, which correlated with FN400 activity. No group differences were found in the late ERP positive components indexing classic old-new amplitude effects. Our combined ERP and fMRI results suggest that sensation-seeking personality affects the early brain responses to visual processing, but not the later stage of memory recognition.

    2013-03-01

    We performed a systematic review of literature on violence and related health concerns among asylum seekers in high-income host countries. We extracted data from 23 peer-reviewed studies. Prevalence of torture, variably defined, was above 30% across all studies. Torture history in clinic populations correlated with hunger and posttraumatic stress disorder, although in small, nonrepresentative samples. One study observed that previous exposure to interpersonal violence interacted with longer immigration detention periods, resulting in higher depression scores. Limited evidence suggests that asylum seekers frequently experience violence and health problems, but large-scale studies are needed to inform policies and services for this vulnerable group often at the center of political debate.

    High sensation seekers engage in more frequent substance use and perceive a host of potentially dangerous activities as less risky than do low sensation seekers. However, despite a plethora of research on these topics, no study has examined the extent to which personal substance use mediates the association between sensation seeking and perceived risk of substance use. To address this question, we recruited a sample of 79 young adults (mean age=19.1 years, standard deviation=1.4). Participants completed questionnaire measures of sensation seeking, substance use, and perceived risk of co-occurrent substance use. Results from path-analytic modeling indicated that both alcohol use and marijuana use mediated the influence of sensation seeking on perceptions of risk for moderately risky, but not highly risky, pairs of substances. Strengths and limitations of the present study were discussed and directions for future research were suggested.

    This study examined the interactive effects of cigarette package flavour descriptors and sensation seeking on adolescents' brand perceptions. High school students (n = 253) were randomly assigned to one of two experimental conditions and sequentially exposed to cigarette package illustrations for three different brands. In the flavour descriptor condition, the packages included a description of the cigarettes as "cherry", while in the traditional descriptor condition the cigarette brands were described with common phrases found on tobacco packages such as "domestic blend." Following exposure to each package participants' hedonic beliefs, brand attitudes and trial intentions were assessed. Sensation seeking was also measured, and participants were categorised as lower or higher sensation seekers. Across hedonic belief, brand attitude and trial intention measures, there were interactions between package descriptor condition and sensation seeking. These interactions revealed that among high (but not low) sensation seekers, exposure to cigarette packages including sweet flavour descriptors led to more favourable brand impressions than did exposure to packages with traditional descriptors. Among high sensation seeking youths, the appeal of cigarette brands is enhanced through the use of flavours and associated descriptions on product packaging.

    Adolescents with high sensation-seeking tendencies often seek out thrill seeking experiences to satisfy their need for stimulation and sensation. In many cases, sensation-seeking adolescents fulfill their need for stimulation and sensation by using illicit substances. However, not all high sensation seekers use drugs, although the factors that prevent or buffer sensation seeking remain unexplored. This study fills this gap in extant research by examining the role of authoritative parenting as a protective factor that prevents or buffers cigarette and marijuana use by adolescents with high sensation-seeking tendencies. Data from 1461 adolescents attending 6th through 8th grades in central Colorado were gathered during a semester-long classroom-based intervention to prevent the onset or further use of cigarettes. Results indicate that authoritative parenting moderated the effect of sensation seeking on adolescent marijuana attitudes, intentions, and peer influence but not behaviors. Further, authoritative parenting was a stronger influence than sensation seeking on cigarette-related outcomes with just the opposite effect observed for marijuana-related outcomes.

    Globus pharyngis is a frequent symptom in patients who consult an otolaryngologist. In many cases, routine diagnostic work-up including history, clinical examination, and barium swallow fail to revealing the underlying pathogenesis. In a retrospective study, we present 51 selected patients suffering from globus pharyngis of unknown origin who were investigated by high-speed cineradiography in a standardized manner. Twenty-four of the patients enrolled in the study (47.1%) showed functional and/or structural swallowing disorders. In 13 cases (25.5%) dyskinesias of the superior esophagus sphincter muscle were found. Five of these patients (9.8%) also had an inconstant hypopharyngeal diverticulum. Six cases (11.8%) showed laryngeal penetration or tracheal aspiration. In four cases (7.8%) functional disorders of pharyngeal, and in three cases (5.9%) functional disorders of oral bolus transport were found. Furthermore one hypopharyngeal web (1.9%) and two benign tumors (3.9%) were detected. In many cases, varying combinations of these findings occurred. Using high-speed cineradiography for evaluation of globus pharyngis results in an increased incidence of pathologic findings, and thus is an important method for interdisciplinary diagnostic work up of patients suffering from this symptom.

  7. Observations of visual sensations produced by Cerenkov radiation from high-energy electrons

    Ten cancer patients whose eyes were therapeutically irradiated with 6-18 MeV electrons reported visual light sensations. Nine reported seeing blue light and one reported seeing white light. Controls reported seeing no light. Additionally, tests with patients ruled out the x-ray contamination of the electron beam as being important. The photon yield due to Cerenkov radiation produced by radium and its daughters for both electrons and gamma rays was calculated; it was found to account for a turn-of-the-century human observation of the radium phosphene. We conclude that the dominant mechanism of this phosphene is Cerenkov radiation, primarily from betas. From our own patient data, based on the color seen and the Cerenkov production rates, we conclude that the dominant mechanism is Cerenkov radiation and that high-energy electrons are an example of particle induced visual sensations

    The aim of this article was to discuss factors related to the researcher, interpreter and asylum seekers when planning focus group interviews with asylum seekers. Focus group interview is one of the basic data collection methods in descriptive nursing and health research. It has been used in multicultural research, allowing an opportunity to participate without literacy and to have linguistic and cultural support from other participants. Asylum seekers form a specific, vulnerable group, and the growing number of asylum seekers increases the need for research related to them. A culturally, methodologically and ethically high-quality focus group interview is based on the researcher's special knowledge and skills, acknowledgement of asylum seekers as both individuals and part of cultural and communal groups, and careful planning of the interpreter's role during the interviews. © 2017 John Wiley & Sons Ltd.

    Public service announcements (PSAs) are non-commercial broadcast ads that are an important part of televised public health campaigns. "Message sensation value" (MSV), a measure of sensory intensity of audio, visual, and content features of an ad, is an important factor in PSA impact. Some communication theories propose that higher message sensation value brings increased attention and cognitive processing, leading to higher ad impact. Others argue that the attention-intensive format could compete with ad's message for cognitive resources and result in reduced processing of PSA content and reduced overall effectiveness. Brain imaging during PSA viewing provides a quantitative surrogate measure of PSA impact and addresses questions of PSA evaluation and design not accessible with traditional subjective and epidemiological methods. We used Blood Oxygenation Level Dependent (BOLD) functional Magnetic Resonance Imaging (fMRI) and recognition memory measures to compare high and low MSV anti-tobacco PSAs and neutral videos. In a short-delay, forced-choice memory test, frames extracted from PSAs were recognized more accurately than frames extracted from the NV. Frames from the low MSV PSAs were better recognized than frames from the high MSV PSAs. The accuracy of recognition of PSA frames was positively correlated with the prefrontal and temporal, and negatively correlated with the occipital cortex activation. The low MSV PSAs were associated with greater prefrontal and temporal activation, than the high MSV PSAs. The high MSV PSAs produced greater activation primarily in the occipital cortex. These findings support the "dual processing" and "limited capacity" theories of communication that postulate a competition between ad's content and format for the viewers' cognitive resources and suggest that the "attention-grabbing" high MSV format could impede the learning and retention of an ad. These findings demonstrate the potential of using neuroimaging in the design and

    Sensation-seeking is a trait that constitutes an important vulnerability factor for a variety of psychopathologies with high social cost. However, little is understood either about the mechanisms underlying motivation for intense sensory experiences or their neuropharmacological modulation in humans. Here, we first evaluate a novel paradigm to investigate sensation-seeking in humans. This test probes the extent to which participants choose either to avoid or self-administer an intense tactile stimulus (mild electric stimulation) orthogonal to performance on a simple economic decision-making task. Next we investigate in a different set of participants whether this behavior is sensitive to manipulation of dopamine D2 receptors using a within-subjects, placebo-controlled, double-blind design. In both samples, individuals with higher self-reported sensation-seeking chose a greater proportion of mild electric stimulation-associated stimuli, even when this involved sacrifice of monetary gain. Computational modelling analysis determined that people who assigned an additional positive economic value to mild electric stimulation-associated stimuli exhibited speeding of responses when choosing these stimuli. In contrast, those who assigned a negative value exhibited slowed responses. These findings are consistent with involvement of low-level, approach-avoidance processes. Furthermore, the D2 antagonist haloperidol selectively decreased the additional economic value assigned to mild electric stimulation-associated stimuli in individuals who showed approach reactions to these stimuli under normal conditions (behavioral high-sensation seekers). These findings provide the first direct evidence of sensation-seeking behavior being driven by an approach-avoidance-like mechanism, modulated by dopamine, in humans. They provide a framework for investigation of psychopathologies for which extreme sensation-seeking constitutes a vulnerability factor. © The Author 2015. Published by

  12. Sensation Seeking and Adolescent Alcohol Use: Exploring the Mediating Role of Unstructured Socializing With Peers.

    Researchers have theorized that adolescents high in sensation seeking are particularly sensitive to positive reinforcement and the rewarding outcomes of alcohol use, and thus that the personality vulnerability is a direct causal risk factor for alcohol use. In contrast, the routine activity perspective theorizes that part of the effect of sensation seeking on alcohol use goes through the propensity that sensation seekers have towards unstructured socializing with peers. The study tests a model with indirect and direct paths from sensation seeking and participation in unstructured peer socialization to adolescent alcohol use. Cross-sectional data were collected from 360 students in a state-secular Jewish high school (10th to 12th grade) in the center region of Israel. The sample was equally divided between boys (51.9%) and girls (48.1%), respondents' age ranged from 15 to 17 years (mean = 16.02 ± 0.85). Structural equation modeling was used to test the direct and indirect paths. While sensation seeking had a significant direct path to adolescent alcohol use, part of the association was mediated by unstructured socializing with peers. The mediated paths were similar for boys and girls alike. Sensation seeking is primarily biologically determined and prevention efforts are unlikely to modify this personality vulnerability. The results of this study suggest that a promising prevention avenue is to modify extracurricular participation patterns of vulnerable adolescents. © The Author 2017.

    Although impulsivity, sensation-seeking, and part-time employment have each been linked to risky behaviors in adolescents, their inter-relationships are less well-understood. We examined data from adolescents to assess the following predictions: (1) sensation-seeking would relate closely to substance use and gambling; (2) impulsivity would relate closely to alcohol, drug, and gambling problems; and (3) these relationships would be particularly strong among those holding part-time jobs. High-school students (N = 3,106) were surveyed to provide data on impulsivity, sensation-seeking, and part-time job status. Bivariate and logistic regression analyses were conducted to examine relationships with gambling, substance use (i.e., alcohol, cigarettes, and marijuana) and related problems. Both impulsivity and sensation-seeking related significantly to substance use and impulsivity to gambling. Impulsivity had stronger associations with drug and gambling problems than sensation-seeking did. Students with paid part-time jobs were more likely to drink alcohol, binge drink, and use marijuana. Sensation-seeking had a particularly strong relationship to heavy cigarette smoking among students with part-time jobs. Conversely, there was little relationship between part-time job status and smoking among low sensation-seekers. These findings further support the relevance of sensation-seeking, impulsivity, and part-time job status to risky behaviors among adolescents. Sensation-seeking and impulsivity had unique relationships to risky behaviors, in accordance with theory and prior evidence. Impulsive adolescents may be in particular need for interventions to reduce drug use and gambling. Although part-time jobs can be beneficial, parents and caregivers should be mindful of potential negative ramifications of paid work outside the home.

    To examine the extent of nutritional vulnerability seen in a cohort of asylum seekers in Australia. Twenty-one asylum seekers (15 males, 6 females) that used a food bank were interviewed over a 6 week period at the Melbourne based Asylum Seeker Resource Centre about foods consumed in the previous 24-h and any non food bank foods obtained. A basket audit was conducted after participants accessed the food bank on the day of interview, Participants obtained significantly less than the minimum requirements for the Australian Guide to Healthy Eating in the vegetables and legumes (P bank, their primary or sole food source. A high level of nutritional vulnerability was seen in this cohort due to their inability to meet minimum nutritional requirements from their primary food access point. Health professionals working with asylum seeker populations need to be aware of this issue and the resulting potential for longer term ill health as a consequence.

  17. A study on the contribution of body vibrations to the vibratory sensation induced by high-level, complex low-frequency noise

    Full Text Available To investigate the contribution of body vibrations to the vibratory sensation induced by high-level, complex low-frequency noise, we conducted two experiments. In Experiment 1, eight male subjects were exposed to seven types of low-frequency noise stimuli: two pure tones [a 31.5-Hz, 100-dB(SPL tone and a 50-Hz, 100-dB(SPL tone] and five complex noises composed of the pure tones. For the complex noise stimuli, the sound pressure level of one tonal component was 100 dB(SPL and that of another one was either 90, 95, or 100 dB(SPL. Vibration induced on the body surface was measured at five locations, and the correlation with the subjective rating of the vibratory sensation at each site of measurement was examined. In Experiment 2, the correlation between the body surface vibration and the vibratory sensation was similarly examined using seven types of noise stimuli composed of a 25-Hz tone and a 50-Hz tone. In both the experiments, we found that at the chest and the abdomen, the rating of the vibratory sensation was in close correlation with the vibration acceleration level (VAL of the body surface vibration measured at each corresponding location. This was consistent with our previous results and suggested that at the trunk of the body (the chest and the abdomen, the mechanoreception of body vibrations plays an important role in the experience of the vibratory sensation in persons exposed to high-level low-frequency noise. At the head, however, no close correlation was found between the rating of the vibratory sensation and the VAL of body surface vibration. This suggested that at the head, the perceptual mechanisms of vibration induced by high-level low-frequency noise were different from those in the trunk of the body.

    Full Text Available Violence in Mexico rose sharply in response to President Felipe Calderón’s military campaign against drug cartels which began in late 2006. As a consequence, the number of Mexicans who have sought asylum in the United States has grown significantly. In 2013, Mexicans made up the second largest group of defensive asylum seekers (those in removal proceedings in the United States, behind only China (EOIR 2014b. Yet between 2008 and 2013, the grant rate for Mexican asylum seekers in immigration court fell from 23 percent to nine percent (EOIR 2013, 2014b. This paper examines—from the perspective of an attorney who represented Mexican asylum seekers on the US-Mexico border in El Paso, Texas—the reasons for low asylum approval rates for Mexicans despite high levels of violence in and flight from Mexico from 2008 to 2013. It details the obstacles faced by Mexican asylum seekers along the US-Mexico border, including placement in removal proceedings, detention, evidentiary issues, narrow legal standards, and (effectively judicial notice of country conditions in Mexico. The paper recommends that asylum seekers at the border be placed in affirmative proceedings (before immigration officials, making them eligible for bond. It also proposes increased oversight of immigration judges.

    Animal research has outlined a vulnerability trait to drug dependence like behavior. The behavioral characteristic of this vulnerability is hyperactivity in response to a novel environment of which sensation seeking (SS) has been suggested as a possible equivalent in humans. If this is the case, SS should be more frequent in drug dependent and risky sports practicing subjects then controls. The objective of this study was to determine if opioid dependent subjects (ODS) and regular paragliders (RP) would be more SS then normal controls. Cross sectional study. Three groups of 34 individuals (total 102) matched for age and sex were selected from ODS seeking treatment, a paragliding club, and a college staff. Global and sub-scores of the Zuckerman sensation seeking scale (SSS). Non parametric statistics (Kruskal Wallis and Wilcoxon 2-Sample Tests) were used given the non-normal distribution of SSS scores in the ODS and RP groups. Significant differences were found across the three groups for the Thrill and Adventure Seeking (TAS) (P = 0.001), dishinibition (Dis) (P = 0.0003) and total score (P = 0.001). ODS and RP scored significantly higher than controls on two (Dis and the TAS scales). RP also scored significantly higher on the Boredom Susceptibility (BS) scale (P = 0.04). Our results show that RP and ODS differ from controls and have some similarities based on the SSS. In this study, the ODS and the RP could express different forms of a general tendency to seek intense and abrupt sensations through various behaviors. Our results in humans are in favor of the hypothesis that the behavioral trait of vulnerability to drug dependence behavior is expressed through SS. Copyright 2002 Elsevier Science Ireland Ltd.

    Visual sensations were experienced when bursts of high-energy pions passed through the dark-adapted right eyes of three human subjects. The threshold for a visual sensation was typically 1 to 3 μrad at the retina. Data are presented to show that the mechanism is Cerenkov radiation generated within the vitreous humor. Threshold measurements agree with published optical data. A comparison is made between our observations and the light flashes observed in deep space by Apollo astronauts

  7. Comparative Evaluation of Tactile Sensation by Electrical and Mechanical Stimulation.

    2017-01-01

    An electrotactile display is a tactile interface that provides tactile perception by passing electrical current through the surface of the skin. It is actively used instead of mechanical tactile displays for tactile feedback because of several advantages such as its small and thin size, light weight, and high responsiveness. However, the similarities and differences between these sensations is still not clear. This study directly compares the intensity sensation of electrotactile stimulation to that of mechanical stimulation, and investigates the characteristic sensation of anodic and cathodic stimulation. In the experiment, participants underwent a 30 pps electrotactile stimulus every one second to their middle finger, and were asked to match this intensity by adjusting the intensity of a mechanical tactile stimulus to an index finger. The results showed that anodic stimulation mainly produced vibration sensation, whereas cathodic sensation produced both vibration and pressure sensations. Relatively low pressure sensation was also observed for anodic stimulation but it remains low, regardless of the increasing of electrical intensity.

    Sensations experienced in the mouth influence food choices, both immediately and in the long term. Such sensations are themselves influenced by experience with flavors, the chemical environment of the mouth, genetics of receptors for flavors, and individual behavior in the chewing of food. Gustation, the sense of taste, yields information about nutrients, influences palatability, and feeds into the human body's preparation to receive those nutrients. Olfaction, the sense of smell, contributes enormously to defining and identifying food flavors (and is experienced even after placing food inside the mouth). Another vital component of food flavor is texture, which contributes to palatability, especially if a food's texture violates a person's expectations. Next, chemesthesis is the sense of chemically induced irritancy and temperature, for example spiciness and stinging. All of these sensations are potentially modified by saliva, the chemical and physical media of the mouth. As a person experiences the culmination of these oral sensations, modified through an individual's own unique saliva, the flavors in turn influence both what and how a person eats.

    To document the natural course of sensation seeking from childhood to adolescence, characterize distinct sensation seeking trajectories, and examine how these trajectories vary according to selected predictors. Data were obtained from the Boricua Youth Study, a longitudinal study of 2,491 children and adolescents of Puerto Rican background (3 assessments from 2000 to 2004). First, age-specific sensation seeking levels were characterized, and then age-adjusted residuals were analyzed using growth mixture models. On average, sensation seeking was stable in childhood (ages 5-10 years) and increased during adolescence (ages 11-17 years). Mean scores of sensation seeking were higher in the South Bronx versus Puerto Rico and among males versus females. Four classes of sensation seeking trajectories were observed: most study participants had age-expected sensation seeking trajectories following the average for their age ("normative," 43.8%); others (37.2%) remained consistently lower than the expected average for their age ("low" sensation seeking); some (12.0%) had an "accelerated" sensation seeking trajectory, increasing at a faster rate than expected; and a minority (7.0%) had a decreasing sensation seeking trajectory that started high but decreased, reaching scores slightly higher than the age-average sensation seeking scores ("stabilizers"). Site (South Bronx versus Puerto Rico) and gender were predictors of membership in a specific class of sensation seeking trajectory. It is important to take a developmental approach when examining sensation seeking and to consider gender and the social environment when trying to understand how sensation seeking evolves during childhood and adolescence.

    Numerous studies have linked the high rates of traumatic events experienced by refugees to the elevated rate of mental health problems in these populations. A growing body of evidence has also highlighted the importance of considering postmigratory stressors when making sense of displaced person distress. This study explored the relationship between mental health and postmigratory stress for asylum seekers and refused asylum seekers in Britain. The study further examined if those refused asylum experienced elevated distress and postmigratory stress compared to those awaiting the outcome of asylum applications. Results indicated that participants ( N = 97) had endured a range of pre- and postmigratory stressors and had high scores on measures of anxiety, depression, and PTSD. A postmigratory factor comprising items associated with isolation, restrictive policies, and stressors associated with having an insecure immigration status, was significantly associated with PTSD scores. This relationship remained when controlling for the variance accounted for by premigratory trauma predictors. Being refused asylum was the strongest predictor of depression and anxiety. Those refused asylum scored higher on a factor associated with barriers to accessing services. Social materialist theories of distress are drawn upon to contextualise the heightened vulnerability of those refused asylum. The paper concludes by emphasising the problems associated with taking an exclusively trauma-focussed approach when working with asylum seekers and argues for community orientated interventions to support displaced people to cope with the various stressors endured in exile.

    2010-01-01

    Professor Yoichi Ando, acoustic architectural designer of the Kirishima International Concert Hall in Japan, presents a comprehensive rational-scientific approach to designing performance spaces. His theory is based on systematic psychoacoustical observations of spatial hearing and listener preferences, whose neuronal correlates are observed in the neurophysiology of the human brain. A correlation-based model of neuronal signal processing in the central auditory system is proposed in which temporal sensations (pitch, timbre, loudness, duration) are represented by an internal autocorrelation representation, and spatial sensations (sound location, size, diffuseness related to envelopment) are represented by an internal interaural crosscorrelation function. Together these two internal central auditory representations account for the basic auditory qualities that are relevant for listening to music and speech in indoor performance spaces. Observed psychological and neurophysiological commonalities between auditor...

    Sensation seeking leads to violence—runs an influential hypothesis in the social scientific study of violent behavior. Although studies confirm that violence is sometimes structured by sensation-seeking motives, the literature seldom comments on the limits to this explanation of violence....... The present study examines the scale of violence motivated by sensation seeking and the degree to which there are several distinct forms of sensation seeking motives operative in violence, rather than a sensation-seeking motive in the singular. The study draws on a sample of situations from Copenhagen...... involving street violence, which are coded quantitatively and qualitatively. Our analysis shows that sensation seeking only seldom seems to play a role in the structuring of street violence. Moreover, the data indicate that sensation seeking finds expression in street violence situations in two different...

    High-intensity focused ultrasound (HIFU) in combination with palliative standard therapy is an innovative and effective treatment option for pain reduction in patients with inoperable pancreatic cancer. Evaluation of the effects of additive ultrasound (US)-guided HIFU treatment in inoperable pancreatic cancer on the sensory and affective pain perception using validated questionnaries. In this study 20 patients with locally advanced inoperable pancreatic cancer and tumor-related pain were treated by US-guided HIFU (6 stage III, 12 stage IV according to UICC and 2 with local recurrence after surgery). Ablation was performed using the JC HIFU system (HAIFU, Chongqing, China) with an ultrasonic device for real-time imaging. Clinical assessment included evaluation of pain severity using validated questionnaires with particular attention to the pain sensation scale (SES) with its affective and sensory component and the numeric rating scale (NRS). The average pain reduction after HIFU was 2.87 points on the NRS scale and 57.3 % compared to the mean baseline score (n = 15, 75 %) in 19 of 20 treated patients. Four patients did not report pain relief, however, the previous opioid medication could be stopped (n = 2) or the analgesic dosage could be reduced (n = 2). No pain reduction was achieved in one patient. Furthermore, after HIFU emotional as well as sensory pain aspects were significantly reduced (before vs. 1 week after HIFU, p pain scales). US-guided HIFU can be used for effective and early pain relief and reduction of emotional and sensory pain sensation in patients with locally advanced pancreatic cancer.

    Compared with other imaging methods such as millimeter wave imaging, infrared imaging and visible light imaging, laser imaging provides both a 2-D array of reflected intensity data as well as 2-D array of range data, which is the most important data for use in autonomous target acquisition .In terms of application, it can be widely used in military fields such as radar, guidance and fuse. In this paper, we present a laser active imaging seeker system based on range-gated laser transmitter and sensor technology .The seeker system presented here consist of two important part, one is laser image system, which uses a negative lens to diverge the light from a pulse laser to flood illuminate a target, return light is collected by a camera lens, each laser pulse triggers the camera delay and shutter. The other is stabilization gimbals, which is designed to be a rotatable structure both in azimuth and elevation angles. The laser image system consists of transmitter and receiver. The transmitter is based on diode pumped solid-state lasers that are passively Q-switched at 532nm wavelength. A visible wavelength was chosen because the receiver uses a Gen III image intensifier tube with a spectral sensitivity limited to wavelengths less than 900nm.The receiver is image intensifier tube's micro channel plate coupled into high sensitivity charge coupled device camera. The image has been taken at range over one kilometer and can be taken at much longer range in better weather. Image frame frequency can be changed according to requirement of guidance with modifiable range gate, The instantaneous field of views of the system was found to be 2×2 deg. Since completion of system integration, the seeker system has gone through a series of tests both in the lab and in the outdoor field. Two different kinds of buildings have been chosen as target, which is located at range from 200m up to 1000m.To simulate dynamic process of range change between missile and target, the seeker system has

    In order to meet the application requirement of a certain long wavelength infrared (LWIR) seeker, a small volume, light weight and passively athermalized infrared (IR) objective is designed in this paper. The two-lens telephoto structure is adopted by merely using aluminum alloy as the housing material. By balancing the thermo-optical coefficient and thermal expansion coefficient of materials, an athermalized IR seeker with effective focal length of 90 mm and F number of 1.2 is achieved. The whole optical length is 75 mm, and the weight is only 234 g. The objective can remain fine imaging quality under temperature range from -40 °C to 60 °C, which is beneficial to the lightweight design of IR seekers.

  16. From sensation to cognition.

    Science.gov (United States)

    Mesulam, M M

    1998-06-01

    Sensory information undergoes extensive associative elaboration and attentional modulation as it becomes incorporated into the texture of cognition. This process occurs along a core synaptic hierarchy which includes the primary sensory, upstream unimodal, downstream unimodal, heteromodal, paralimbic and limbic zones of the cerebral cortex. Connections from one zone to another are reciprocal and allow higher synaptic levels to exert a feedback (top-down) influence upon earlier levels of processing. Each cortical area provides a nexus for the convergence of afferents and divergence of efferents. The resultant synaptic organization supports parallel as well as serial processing, and allows each sensory event to initiate multiple cognitive and behavioural outcomes. Upstream sectors of unimodal association areas encode basic features of sensation such as colour, motion, form and pitch. More complex contents of sensory experience such as objects, faces, word-forms, spatial locations and sound sequences become encoded within downstream sectors of unimodal areas by groups of coarsely tuned neurons. The highest synaptic levels of sensory-fugal processing are occupied by heteromodal, paralimbic and limbic cortices, collectively known as transmodal areas. The unique role of these areas is to bind multiple unimodal and other transmodal areas into distributed but integrated multimodal representations. Transmodal areas in the midtemporal cortex, Wernicke's area, the hippocampal-entorhinal complex and the posterior parietal cortex provide critical gateways for transforming perception into recognition, word-forms into meaning, scenes and events into experiences, and spatial locations into targets for exploration. All cognitive processes arise from analogous associative transformations of similar sets of sensory inputs. The differences in the resultant cognitive operation are determined by the anatomical and physiological properties of the transmodal node that acts as the critical

    The purpose of the present study was to compare admission rates, including admission by coercion, length of hospital stay and diagnosis among immigrants, asylum seekers and Norwegian-born patients. All admissions (n=3053) to Østmarka Hospital during the period 1995-2000 were examined. A sample including all immigrants (94) and asylum seekers (39) as well as a control group of 133 Norwegians was analysed. Immigrants and Norwegians had the same relative risk of admission (1.07). The relative risk of admission was higher for asylum seekers compared to Norwegians (8.84). There were differences in the diagnoses given at discharge in the three groups of patients, both among men (chi2=22.33, df=6, pimmigrants. The number of admissions by coercion was highest among immigrants, and lowest among asylum seekers (chi2=12.03, df=2, pimmigrants, asylum seekers had high admission rates and low frequency of admissions by coercion. Schizophrenia was frequent among female immigrants admitted to hospital.

    Provoked vestibulodynia (PVD) is characterized by the presence of vulvar touch and pain hypersensitivity. Pain with vaginal distension, which motivates treatment seeking and perpetuates distress, is frequently reported with PVD. However, the concordance between the perception of vulvar and vaginal sensation (ie, somatic and visceral genital sensations, respectively) remains unstudied in healthy women, as well as in clinical populations such as PVD. To evaluate the static and dynamic (time-varying) properties of somatic and visceral genital sensation, women with PVD (n=14) and age- and contraceptive-matched healthy controls (n=10) rated varying degrees of nonpainful and painful genital stimulation. Somatic (vulvar) mechanical sensitivity to nonpainul and painful degrees of force were compared to visceral (vaginal) sensitivity to nonpainful and painful distension volumes. Results indicated that healthy women showed substantial individual variation in and high discrimination of vulvar and vaginal sensation. In contrast, PVD was associated with vulvar allodynia and hyperalgesia, as well as vaginal allodynia. Modeling of dynamic perception revealed novel properties of abnormal PVD genital sensation, including temporal delays in vulvar touch perception and reduced perceptual thresholds for vaginal distension. The temporal properties and magnitude of PVD distension pain were indistinguishable from vaginal fullness in healthy controls. These results constitute the first empirical comparison of somatic and visceral genital sensation in healthy women. Findings provide novel insights into the sensory abnormalities that characterize PVD, including an experimental demonstration of visceral allodynia. This investigation challenges the prevailing diagnostic assessment of PVD and reconceptualizes PVD as a chronic somatic and visceral pain condition. Copyright © 2013. Published by Elsevier B.V.

    An Austrian Non-Governmental Organization (NGO) offered psychotherapy to 37 asylum seekers and refugees (21 of them female) with a mean age of 36.1 years (s = 7.5), with the majority of them from Chechnya or Afghanistan. Comparative data between the start of therapy and the time of evaluation revealed a highly significant positive effect (d = 0.77), while most therapies were still going on. By a retrospective measure of perceived change, 85% of the participants reported significant improvements. The results show that even under difficult conditions, when working with asylum seekers and refugees, psychotherapy can be effective.

    The goal of the present study was to explore high-frequency rotation sensation function damage of the crista of the horizontal semicircular canal induced by gentamicin and its morphological basis. The guinea pigs were randomly divided into four groups (group 1, 2, 3 and control group, n=20). The animals of treated groups received gentamicin subcutaneously (50 mg/kg per day) for 1 week (group 1), 2 weeks (group 2) and 3 weeks (group 3), respectively. The animals of control group were administered with equal volume of saline subcutaneously. Videonystagmography (VNG) evoked by ice water or high-frequency rotations, and vestibular evoked potential (VsEP) evoked by low- and high-frequency rotations were recorded after the administration. After VNG and VsEP were examined, the cristae of the horizontal semicircular canals were prepared for scanning and transmission electron microscopy. The results are as follows: (1) In VNG examination, after ice water stimulation, no obvious nystagmus was observed in the animals of group 3, and there was no significant difference in nystagmus frequency and duration among group 1, 2 and control group (P>0.05). After high- frequency rotations, no obvious nystagmus was yet observed in the animals of group 3. There were significant differences in the nystagmus frequency and duration of the VNG waves between the experimental group 2 and control group (P0.05). (2) In VsEP examination, there was no significant difference in the parameters of VsEP among group 1, 2 and control group (P>0.05), and VsEP was not observed in group 3 after low-frequency rotations. After high- frequency rotations, compared with control group, the latencies and amplitudes of P1 and P2 in group 2 significantly decreased (P0.05). Group 3 had no response of VsEP to high-frequency rotations. (3) Electron microscopy was used to observe the crista hair cells of the four groups. In control group, the hair cells were normal. In group 1, almost normal appearance with slight

    To establish the extent to which representative cognitive functions in subjects undergoing magnetic resonance (MR) imaging are acutely impaired by static magnetic fields of varying field strengths. This study was approved by the local ethics committee, and informed consent was obtained from all subjects. In this single-blind case-crossover study, 41 healthy subjects underwent an extensive neuropsychologic examination while in MR units of differing field strengths (1.5, 3.0, and 7.0 T), including a mock imager with no magnetic field as a control condition. Subjects were blinded to field strength. Tests were performed while subjects were lying still in the MR unit and while the examination table was moved. The tests covered a representative set of cognitive functions, such as memory, eye-hand coordination, attention, reaction time, and visual discrimination. Subjective sensory perceptions were also assessed. Effects were analyzed with a repeated-measures analysis of variance; the within-subject factors were field strength (0, 1.5, 3.0, and 7.0 T) and state (static, dynamic). Static magnetic fields were not found to have a significant effect on cognitive function at any field strength. However, sensory perceptions did vary according to field strength. Dizziness, nystagmus, phosphenes, and head ringing were related to the strength of the static magnetic field. Static magnetic fields as high as 7.0 T did not have a significant effect on cognition.

    The prevalence of trauma-related problems among refugees and asylum seekers is extremely high due to adverse experiences associated with forced migration. Although the literature presents a considerable number of guidelines and theoretical frameworks for working with traumatized refugees and asylum seekers, the efficacy, feasibility and applicability of these interventions have little empirical evidence. The purpose of this article is to critically review the literature to provide a rationale for developing culturally sensitive, evidence-based interventions for refugees and asylum seekers. A literature review integrating research findings on interventions designed especially for traumatized asylum seekers and refugees was conducted. Retained studies had to use some quantitative measurements of post-traumatic stress and to have pre- and post-measurements to evaluate the efficacy of the intervention. Studies included in this review cover a wide variety of interventions, including trauma-focused interventions, group therapy, multidisciplinary interventions and pharmacological treatments. The majority of studies with traumatized refugees and asylum seekers reported positive outcomes of the intervention in reducing trauma-related symptoms. There is evidence to support the suitability of cognitive-behavioral therapy (CBT) and narrative exposure therapy (NET) in certain populations of refugees. Other intervention studies are limited by methodological considerations, such as lack of randomization, absence of control group and small samples. This review has again highlighted the shortage of guiding frameworks available to investigators and clinicians who are interested in tailoring interventions to work with refugees and asylum seekers. Theoretical, ethical and methodological considerations for future research are discussed. © The Author(s) 2014.

    Fast, accurate and high-throughput identification of bacterial isolates is in great demand. The present work was conducted to investigate the possibility of identifying isolates from unassembled next-generation sequencing reads using custom-made guide trees. A tool named StrainSeeker was developed that constructs a list of specific k -mers for each node of any given Newick-format tree and enables the identification of bacterial isolates in 1-2 min. It uses a novel algorithm, which analyses the observed and expected fractions of node-specific k -mers to test the presence of each node in the sample. This allows StrainSeeker to determine where the isolate branches off the guide tree and assign it to a clade whereas other tools assign each read to a reference genome. Using a dataset of 100 Escherichia coli isolates, we demonstrate that StrainSeeker can predict the clades of E. coli with 92% accuracy and correct tree branch assignment with 98% accuracy. Twenty-five thousand Illumina HiSeq reads are sufficient for identification of the strain. StrainSeeker is a software program that identifies bacterial isolates by assigning them to nodes or leaves of a custom-made guide tree. StrainSeeker's web interface and pre-computed guide trees are available at http://bioinfo.ut.ee/strainseeker. Source code is stored at GitHub: https://github.com/bioinfo-ut/StrainSeeker.

    2016-05-01

    Germany is one of the most important host countries for minor refugees and asylum seekers in Europe. The number of children who leave their home country has significantly risen worldwide in recent years; a further rise is to be expected due to the increasing number of crisis zones. A literature review demonstrates the state of research on traumatization, post-traumatic stress disorders and psychotherapy in minor refugees and asylum seekers. Many minor refugees and asylum seekers have made mainly interpersonal traumatic experiences within their home country or during their flight and develop simple or complex post-traumatic stress disorders. Left untreated, there is a risk of chronification. The psychotherapeutic treatment of minor refugees and asylum seekers in Germany takes place primarily in specialized psychosocial treatment centers. For an involvement of therapists in private practices, a reduction of organizational barriers as well as evidence-based treatment methods for interpreter-aided psychotherapy of minor refugees and asylum seekers that also consider their developmental state, are still lacking. In research, as well as in practice, there is further need for an early and systematic identification and treatment of minor refugees and asylum seekers with post-traumatic stress disorders or high risk of disease in Germany.

    Studies in western samples have shown that post-traumatic stress disorder (PTSD) and depression are associated with overgeneral autobiographical memory retrieval. This study assesses whether this association extends to asylum seekers and refugees from diverse cultural backgrounds. We discuss implications for those providing testimony of their experiences when seeking asylum. 38 asylum seekers and refugees were recruited through clinics and community groups. Clinical interviews assessed PTSD and depression and participants completed a test of autobiographical memory specificity. When accounting for omissions, participants with PTSD and depression recalled a lower proportion of specific memories. Those with PTSD also failed more frequently to report any memory. The sample did not permit separate evaluation of the effects of PTSD and depression on specificity. Lower memory specificity observed in people experiencing PTSD and depression in western populations extends to asylum seekers and refugees from diverse cultural backgrounds. This study adds to the literature suggesting that being recognised as a refugee fleeing persecution is more difficult for those with post-traumatic symptoms and depression.

    Full Text Available While most of the world's refugees reside in developing countries, their arrival to western countries is highly politicised, giving rise to questions about the types of entitlements and rights that should, or should not, be granted. In this study, using a mixed-methods community questionnaire (N = 185, we examined attitudes towards social policies aimed at providing assistance to two categories of new arrivals to Australia: resettled refugees (who arrive via its official refugee resettlement program and asylum seekers (who arrive via boat and then seek refugee status. Social policy attitude was examined as a consequence of feelings of anger, fear, and threat, as well as levels of prejudice. Participants felt significantly higher levels of anger, fear, threat, and prejudice towards asylum seekers compared to resettled refugees. For both resettled refugees and asylum seekers, prejudice was an independent predictor of more restrictive social policy attitudes. For resettled refugees, fear and perceived threat were independent predictors for more restrictive social policy whereas for asylum seekers anger was an independent predictor of restrictive social policy. The qualitative data reinforced the quantitative findings and extended understanding on the appraisals that underpin negative attitudes and emotional responses. Practical implications relating to challenging community attitudes are discussed.

  10. Safe in our hands?: a study of suicide and self-harm in asylum seekers.

    This study examined the incidence of suicide and self-harm in asylum seekers in the UK, both those in detention and in the community. The investigation revealed that data recording is seriously flawed or sometimes non-existent. However, the scanty data those were available from Immigration Removal Centres, coroners' records and Prison Ombudsman's reports showed high levels of self-harm and suicide for detained asylum seekers as compared with the United Kingdom prison population. It is suggested that this could be attributed to routine failure to observe and mitigate risk factors. The author makes the following recommendations: coroners should record asylum seeker status and ethnicity of deceased, self-harm monitoring in the community should record asylum seeker status and ethnicity, health care in immigration removal centres should meet the same standards as UK prisons as a minimum, allegation of torture by immigration detainees should trigger a case management review and risk assessment for continued detention, and this process should be open to audit, and interpreters should be used for mental state examinations unless their English has been shown to the fluent.

    This study aimed to describe, compare, and predict mental health outcomes of different migrant groups and native residents in Switzerland. Asylum seekers (n=65); refugees holding permanent protection visas (n=34); illegal migrants (n=21); labor migrants (n=26); and residents (n=56) completed an assessment by questionnaire. Main outcome variables were symptoms of posttraumatic stress, anxiety and depression. It was tested whether resident status predicted psychopathology over and above the influence of control variables including social desirability, traumatic event types and post-migration resources. Asylum seekers (54.0%) and refugees (41.4%) fulfilled criteria of PTSD most frequently. Clinically relevant symptoms of anxiety and depression were most frequently reported by asylum seekers (84.6% and 63.1%, resp.) and illegal migrants (both 47.6%). Resident status contributed to psychopathology over and above the influence of control variables. Overall, asylum seekers, refugees, and illegal migrants showed high psychiatric morbidity. Differences in resident status appear to be specifically associated with mental health outcomes. This association persists even when controlling for social desirability, post-migration resources and traumatic events. This emphasizes the importance of current socio-political living conditions for mental health, even with respect to the psychopathological sequelae of past traumatic experiences.

    Objectives: Asylum seekers in Germany represent a highly vulnerable group from a health perspective. Furthermore, their access to healthcare is restricted. While the introduction of the Electronic Health Insurance Card (EHIC) for asylum seekers instead of healthcare-vouchers is discussed controversially using politico-economic reasons, there is hardly any empirical evidence regarding its actual impact on the use of medical services. The aim of the study is to examine this impact on the use of medical services by asylum seekers as measured by their consultation rate of ambulant physicians (CR). Study Design: For this purpose, a standardized survey was conducted with 260 asylum seekers in different municipalities, some of which have introduced the EHIC for asylum seekers, while others have not. Methods: The period prevalence was compared between the groups “with EHIC” and “without EHIC” using a two-sided t -test. Multivariate analysis was done using a linear OLS regression model. Results: Asylum seekers in possession of the EHIC are significantly more likely to seek ambulant medical care than those receiving healthcare-vouchers. Conclusions: The results of this study suggest that having to ask for healthcare-vouchers at the social security office could be a relevant barrier for asylum seekers.

    BACKGROUND: Adult refugees and asylum seekers living in Western countries experience a high prevalence of mental health problems, especially post traumatic stress disorder (PTSD), depression and anxiety. This study compares and contrasts the prevalence of health problems, and potential risk factors as well as the utilisation of health services by asylum seekers and refugees in the Irish context. METHODS: Cross sectional study using validated self reported health status questionnaires of adult asylum seekers (n = 60) and refugees (n = 28) from 30 countries, living in Ireland. Outcome measures included: general health status (SF-36), presence of PTSD symptoms and anxiety\\/depression symptoms. Data on chronic conditions and pre or post migration stressors are also reported. The two groups are compared for utilisation of the health care system and the use of over the counter medications. RESULTS: Asylum seekers were significantly more likely than refugees to report symptoms of PTSD (OR 6.3, 95% CI: 2.2-17.9) and depression\\/anxiety (OR 5.8, 95% CI: 2.2-15.4), while no significant difference was found in self-reported general health. When adjusted by multivariable regression, the presence of more than one chronic disease (OR 4.0, 95%CI: 1.3-12.7; OR 3.4, 95% CI: 1.2-10.1), high levels of pre migration stressors (OR 3.6, 95% CI: 1.1-11.9; OR 3.3, 95% CI: 1.0-10.4) or post migration stressors (OR 17.3, 95% CI: 4.9-60.8; OR 3.9, 95% CI: 1.2-12.3) were independent predictors of self reported PTSD or depression\\/anxiety symptoms respectively, however, residence status was no longer significantly associated with PTSD or depression\\/anxiety. Residence status may act as a marker for other explanatory variables; our results show it has a strong relationship with post migration stressors (chi2 = 19.74, df = 1, P < 0.001).In terms of health care utilisation, asylum seekers use GP services more often than refugees, while no significant difference was found between these groups

    Motorcycles are the leading cause of road traffic deaths in the Western Pacific and Southeast Asia, where Mandarin Chinese is the most commonly used language. Sensation seeking (SS) is reported to correlate with many risky motor vehicle behaviors, and therefore a culture-adapted Chinese instrument is needed to assess this personality trait in Chinese-speaking motorcycling populations. The standard front and blinded-backward process was carried out to formulate the Chinese-language Brief Sensation Seeking Scale (C-BSSS). 193 parental motorcyclists who rode with their young children were interviewed concerning their SS levels, demographics, riding behaviors, and the driving/riding experiences. A random sample of 30 subjects was re-interviewed 1-2 weeks later to examine the test-retest reliability. Psychometric analyses revealed satisfactory item characteristics, internal consistency, intraobserver reliability, and interobserver reliability. Additionally, parental motorcyclists who had the following characteristics were more likely to be the high sensation seekers (SSers), including male, younger age, presenting risky motor vehicle behaviors of themselves (e.g., higher riding speeds, operating after drinking, using a mobile phone while operating, and receiving a traffic ticket), and carrying child passengers who demonstrated dangerous motorcycling behaviors (e.g., a younger age, non-helmeted, and overloaded). We conclude that the C-BSSS is a useful and reliable measure of SS for ethnic Chinese populations. This instrument may be helpful to develop the future prevention strategy of motorcycle injuries in Chinese parental motorcyclists and their young child passengers. Copyright © 2014.

    Full Text Available Abstract Background Several suicide and suicidal behaviour risk factors are highly prevalent in asylum seekers, but there is little insight into the suicide death rate and the suicidal behaviour incidence in this population. The main objective of this study is to assess the burden of suicide and hospital-treated non-fatal suicidal behaviour in asylum seekers in the Netherlands and to identify factors that could guide prevention. Methods We obtained data on cases of suicide and suicidal behaviour from all asylum seeker reception centres in the Netherlands (period 2002-2007, age 15+. The suicide death rates in this population and in subgroups by sex, age and region of origin were compared with the rate in the Dutch population; the rates of hospital-treated suicidal behaviour were compared with that in the population of The Hague using indirect age group standardization. Results The study included 35 suicide deaths and 290 cases of hospital-treated suicidal behaviour. The suicide death rate and the incidence of hospital-treated suicidal behaviour differed between subgroups by sex and region of origin. For male asylum seekers, the suicide death rate was higher than that of the Dutch population (N = 32; RR = 2.0, 95%CI 1.37-2.83. No difference was found between suicide mortality in female asylum seekers and in the female general population of the Netherlands (N = 3; RR = 0.73; 95%CI 0.15-2.07. The incidence of hospital-treated suicidal behaviour was high in comparison with the population of The Hague for males and females from Europe and the Middle East/South West Asia, and low for males and females from Africa. Health professionals knew about mental health problems prior to the suicidal behaviour for 80% of the hospital-treated suicidal behaviour cases in asylum seekers. Conclusions In this study the suicide death rate was higher in male asylum seekers than in males in the reference population. The incidence of hospital-treated suicidal behaviour

    An unknown number of asylum seekers arriving in Denmark have been exposed to torture or have experienced other traumatising events in their country of origin. The health of traumatised asylum seekers, both physically and mentally, is affected upon arrival to Denmark, and time in asylum centres leads to further deterioration in health. One hundred forty-two (N=142) newly arrived asylum seekers were examined at Center Sandholm by Amnesty International Danish Medical Group from the 1st of September until the 31st of December 2007. The asylum seekers came from 33 different countries, primarily representing Afghanistan, Iraq, Iran, Syria, and Chechnya. Of the asylum seekers, 45 percent had been exposed to torture--approximately one-third within the year of arrival to Denmark. Unsystematic blows, personal threats or threats to family, degrading treatment, isolation, and witnessing torture of others were the main torture methods reported. The majority of the asylum seekers had witnessed armed conflict, persecution, and imprisonment. The study showed that physical symptoms were approximately twice as frequent and psychological symptoms were approximately two to three times as frequent among torture survivors as among non-tortured asylum seekers. However, even the health of non-tortured asylum seekers was affected. Among the torture survivors, 63 percent fulfilled the criteria for post-traumatic stress disorder, and 30-40 percent of the torture survivors were depressed, in anguish, anxious, and tearful in comparison to 5-10 percent of the non-tortured asylum seekers. Further, 42 percent of torture survivors had torture-related scars. Torture survivors amid newly arrived asylum seekers are an extremely vulnerable group, hence examination and inquiry about the torture history is extremely important in order to identify this population to initiate the necessary medical treatment and social assistance.

  1. Opponency of astringent and fat sensations.

    In most cultures, people ingest a variety of astringent foods and beverages during meals, but the reasons for this practice are unclear. Many popular beliefs and heuristics, such as high tannin wines should be balanced with fatty foods, for example 'red wine with red meat', suggest that astringents such as pickles, sorbets, wines, and teas 'cleanse' the palate while eating. Oral astringents elicit 'dry, rough' sensations [1], in part, by breaking down mucinous lubricating proteins in saliva [2,3]. The introduction of oral lubricants, including fats, partially diminishes strong astringent sensations [4,5]. Thus, it appears that astringency and fattiness can oppose each other perceptually on an oral rheological spectrum. Most teas, wines, and 'palate cleansers', however, are only mildly astringent and an explanation of how they could oppose the fattiness of meals is lacking. Here, we demonstrate that weakly astringent stimuli can elicit strong sensations after repeated sampling. Astringency builds with exposures [6] to an asymptotic level determined by the structure and concentration of the compound. We also establish that multiple sips of a mild astringent solution, similar to a wine or tea, decrease oral fat sensations elicited by fatty food consumption when astringent and fatty stimuli alternate, mimicking the patterning that occurs during a real meal. Consequently, we reveal a principle underlying the international practice of 'palate cleansing'. Repeatedly alternating samples of astringent beverages with fatty foods yielded ratings of fattiness and astringency that were lower than if rinsing with water or if presented alone without alternation.

    Asylum seekers and refugees experience a range of barriers to health service access and competent use. The Refugee Health Nurse Liaison initiative was piloted at a hospital in a high-settlement region of Victoria, Australia. This initiative aimed to build capacity within the health sector to more effectively respond to the needs of asylum seekers and refugees. A mixed-methods evaluation was undertaken to: describe issues encountered by asylum seekers and refugees within the hospital setting; capture the nature of the Refugee Health Nurse Liaison position; and document key outputs. Throughout the pilot period, 946 patients were referred to the role, of which 99% received an assessment of physical, mental, and social health. Refugee Health Nurse Liaisons effectively provided clinical support, advocacy, education, referrals, and both formal and informal capacity building. Learnings from this model are transferable to services in high-settlement regions, and could have application in improving patient care more broadly.

    Full Text Available Substantial acute and chronic intakes of alcohol or ethanol (EtOH severely influence oral sensations, such as thirst and oral dryness (dry mouth, xerostomia. Thirst sensation and oral dryness are primarily caused by the activation of neurons in brain regions, including the circumventricular organs and hypothalamus, which are referred to as the dipsogenic center, and by a decrease in salivary secretion, respectively. The sensation of thirst experienced after heavy-alcohol drinking is widely regarded as a consequence of EtOH-induced diuresis; however, EtOH in high doses induces anti-diuresis. Recently, it has been proposed that the ethanol metabolite acetaldehyde induces thirst via two distinct processes in the central nervous system from EtOH-induced diuresis, based on the results of animal experiments. The present review describes new insights regarding the induction mechanism of thirst sensation and oral dryness after drinking alcohol.

    Full Text Available Abstract Background A small body of evidence demonstrates the challenges faced by migrant communities living with HIV but has yet to consider in-depth the experience of asylum seekers whose residency status is undetermined. The overall aim of our study was to explore the experiences of those who are both living with HIV and seeking asylum. This paper focuses on the stressors precipitated by the HIV diagnosis and by going through the asylum system; as well as participants’ resilience in responding to these stressors and the consequences for their health and wellbeing. Methods We conducted an ethnographic study. Fieldwork took place in the UK between 2008–2009 and included: 350 hours of observation at voluntary services providing support to black and minority ethnic groups living with HIV; 29 interviews and four focus group discussions with those who were seeking asylum and living with HIV; and 15 interviews with their health and social care providers. Data were analysed using the constant comparative method. Results There were three main stressors that threatened participants’ resilience. First, migration caused them to leave behind many resources (including social support. Second, stigmatising attitudes led their HIV diagnosis to be a taboo subject furthering their isolation. Third, they found themselves trapped in the asylum system, unable to influence the outcome of their case and reliant on HIV treatment to stay alive. Participants were, however, very resourceful in dealing with these experiences. Resilience processes included: staying busy, drawing on personal faith, and the support received through HIV care providers and voluntary organisations. Even so, their isolated existence meant participants had limited access to social resources, and their treatment in the asylum system had a profound impact on perceived health and wellbeing. Conclusions Asylum seekers living with HIV in the UK show immense resilience. However, their isolation

    Adult refugees and asylum seekers living in Western countries experience a high prevalence of mental health problems, especially post traumatic stress disorder (PTSD), depression and anxiety. This study compares and contrasts the prevalence of health problems, and potential risk factors as well as the utilisation of health services by asylum seekers and refugees in the Irish context. Cross sectional study using validated self reported health status questionnaires of adult asylum seekers (n = 60) and refugees (n = 28) from 30 countries, living in Ireland. Outcome measures included: general health status (SF-36), presence of PTSD symptoms and anxiety/depression symptoms. Data on chronic conditions and pre or post migration stressors are also reported. The two groups are compared for utilisation of the health care system and the use of over the counter medications. Asylum seekers were significantly more likely than refugees to report symptoms of PTSD (OR 6.3, 95% CI: 2.2-17.9) and depression/anxiety (OR 5.8, 95% CI: 2.2-15.4), while no significant difference was found in self-reported general health. When adjusted by multivariable regression, the presence of more than one chronic disease (OR 4.0, 95%CI: 1.3-12.7; OR 3.4, 95% CI: 1.2-10.1), high levels of pre migration stressors (OR 3.6, 95% CI: 1.1-11.9; OR 3.3, 95% CI: 1.0-10.4) or post migration stressors (OR 17.3, 95% CI: 4.9-60.8; OR 3.9, 95% CI: 1.2-12.3) were independent predictors of self reported PTSD or depression/anxiety symptoms respectively, however, residence status was no longer significantly associated with PTSD or depression/anxiety. Residence status may act as a marker for other explanatory variables; our results show it has a strong relationship with post migration stressors (chi2 = 19.74, df = 1, P refugees, while no significant difference was found between these groups for use of dentists, medication, hospitalisation or mental health services.

    Objective To document the natural course of sensation seeking from childhood to adolescence, characterize distinct sensation-seeking trajectories, and examine how these trajectories vary according to selected predictors. Method Data were obtained from the Boricua Youth Study, a longitudinal study of 2,491 children and adolescents of Puerto Rican background (three assessments from 2000 to 2004). First, age-specific sensation-seeking levels were characterized. Then, age-adjusted residuals were analyzed using growth mixture models (GMM). Results On average, sensation seeking was stable in childhood (ages 5–10) and increased during adolescence (ages 11–17). Mean scores of sensation seeking were higher in the South Bronx vs. Puerto Rico and among males vs. females. Four classes of sensation-seeking trajectories were observed: most study participants had age-expected sensation-seeking trajectories following the average for their age (“normative,” 43.8%); others (37.2%) remained consistently lower than the expected average for their age (“low” sensation seeking); some (12.0%) had an “accelerated” sensation-seeking trajectory, increasing at a faster rate than expected, while a minority (7.0%) had a decreasing sensation-seeking trajectory that started high but decreased, reaching scores slightly higher than the age-average sensation-seeking scores (“stabilizers”). Site (South Bronx vs. Puerto Rico) and gender were predictors of membership in a specific class of sensation-seeking trajectory. Conclusion It is important to take a developmental approach when examining sensation seeking and to consider gender and the social environment when trying to understand how sensation seeking evolves during childhood and adolescence.

  14. Public health metaphors in Australian policy on asylum seekers.

    2009-02-01

    To analyse the way in which a public health metaphor has been incorporated into Australian political practice to justify the exclusion or mistreatment of unwelcome non-citizens, giving particular attention to recent asylum seekers. Starting with a personal experience of working in an immigration detention centre and then drawing on media reports and published scholarship, I critique political rhetoric and policy on asylum seekers, arguing that the significance of a public health metaphor lies in its effectiveness in persuading the public that refugees and asylum seekers are a moral contaminant that threatens the nation and has to be contained. Acceptance of the metaphor sanctions humanly degrading inferences, policies and actions. Public health professionals therefore have a responsibility to challenge the political use of public health and associated metaphors. Substituting the existing metaphor for one that is more morally acceptable could help to redefine refugees and asylum seekers more positively and promote compassion in political leaders and the community.

  15. Bodily illusions disrupt tactile sensations.

    D'Amour, Sarah; Pritchett, Lisa M; Harris, Laurence R

    2015-02-01

    To accurately interpret tactile information, the brain needs to have an accurate representation of the body to which to refer the sensations. Despite this, body representation has only recently been incorporated into the study of tactile perception. Here, we investigate whether distortions of body representation affect tactile sensations. We perceptually altered the length of the arm and the width of the waist using a tendon vibration illusion and measured spatial acuity and sensitivity. Surprisingly, we found reduction in both tactile acuity and sensitivity thresholds when the arm or waist was perceptually altered, which indicates a general disruption of low-level tactile processing. We postulate that the disruptive changes correspond to the preliminary stage as the body representation starts to change and may give new insights into sensory processing in people with long-term or sudden abnormal body representation such as are found in eating disorders or following amputation.

    To investigate the frequency of traumatisation, suicidality and given diagnoses in expert opinions on asylum seekers and to describe the sociodemographic characteristics of this population. The psychiatric expert opinions on asylum seekers, furnished in an 8-year-period at Hannover Medical School, were analysed retrospectively for qualitative and quantitative characteristics. 62 psychiatric expert opinions on asylum seekers were included in this study. The asylum seekers originated from 18 different countries, mainly from Turkey and former Yugoslavia. Most expert opinions were given in secondary asylum procedures, i. e. after the initial asylum request had been rejected. The asylum seekers reported on traumatisation in 82.3 %. The most frequently reported forms of traumatisation were rape in female, and torture in male persons. According to ICD-10 or DSM-IV-R criteria posttraumatic stress disorder (PTSD) was the most frequent diagnosis (74.1 %) in this study. The second most common diagnoses were depressive disorders (ICD-10: F32.x in 33.9 % and ICD-10: F33.x in 25.9 %). Suicidal tendency was found in 56.5 % of the asylum seekers. Cultural differences, language barriers, a heavy burden by psychological symptoms, and clinical severity are difficulties in the process of psychiatric assessment of refugees in legal asylum procedures. © Georg Thieme Verlag KG Stuttgart · New York.

  17. PeakSeeker: a program for interpreting genotypes of mononucleotide repeats

    Salipante Stephen J

    2009-02-01

    Full Text Available Abstract Background Mononucleotide repeat microsatellites are abundant, highly polymorphic DNA sequences, having the potential to serve as valuable genetic markers. Use of mononucleotide microsatellites has been limited by their tendency to produce "stutter", confounding signals from insertions and deletions within the mononucleotide tract that occur during PCR, which complicates interpretation of genotypes by masking the true position of alleles. Consequently, microsatellites with larger repeating subunits (dinucleotide and trinucleotide motifs are used, which produce less stutter but are less genetically heterogeneous and less informative. A method to interpret the genotypes of mononucleotide repeats would permit the widespread use of those highly informative microsatellites in genetic research. Findings We have developed an approach to interpret genotypes of mononucleotide repeats using a software program, named PeakSeeker. PeakSeeker interprets experimental electropherograms as the most likely product of signals from individual alleles. Because mononucleotide tracts demonstrate locus-specific patterns of stutter peaks, this approach requires that the genotype pattern from a single allele is defined for each marker, which can be approximated by genotyping single DNA molecules or homozygotes. We have evaluated the program's ability to discriminate various types of homozygous and heterozygous mononucleotide loci using simulated and experimental data. Conclusion Mononucleotide tracts offer significant advantages over di- and tri-nucleotide microsatellite markers traditionally employed in genetic research. The PeakSeeker algorithm provides a high-throughput means to type mononucleotide tracts using conventional and widely implemented fragment length polymorphism genotyping. Furthermore, the PeakSeeker algorithm could potentially be adapted to improve, and perhaps to standardize, the analysis of conventional microsatellite genotypes.

    Refugees demonstrate high rates of post-traumatic stress disorder (PTSD) and other psychological disorders. The recent increase in forcible displacement internationally necessitates the understanding of factors associated with refugee mental health. While pre-migration trauma is recognized as a key predictor of mental health outcomes in refugees and asylum seekers, research has increasingly focused on the psychological effects of post-migration stressors in the settlement environment. This article reviews the research evidence linking post-migration factors and mental health outcomes in refugees and asylum seekers. Findings indicate that socioeconomic, social, and interpersonal factors, as well as factors relating to the asylum process and immigration policy affect the psychological functioning of refugees. Limitations of the existing literature and future directions for research are discussed, along with implications for treatment and policy.

  19. Motion sickness history, food neophobia, and sensation seeking.

    Motion sickness is believed to be caused by conflicting sensory signals, a situation that mimics the effects of ingesting certain toxins. Thus, one might suspect that individuals who have experienced a relatively high frequency of motion sickness may be particularly vigilant about avoiding anything that produces nausea, induding potentially nauseating toxins. Consequently, they may be more resistant to trying new foods, i.e., be more food neophobic, since unfamiliar foods can have unexpected adverse effects due to toxins or allergens. Likewise, many highly stimulating experiences can trigger motion sickness, so individuals who are more susceptible may be more prone to avoid such experiences, i.e., be less sensation seeking. Finally, it was expected that food neophobia would be more frequent in individuals low on sensation seeking tendencies. Self-reported motion sickness history in 308 adults (M= 18.8 yr.; SD = 1.6) was correlated with scores on the Arnett Inventory of Sensation Seeking and the Food Neophobia Scale. As predicted, greater history of motion sickness was associated with lower Sensation Seeking scores. Food Neophobia was not correlated with motion sickness history but, as expected, was negatively correlated (r = -.42) with scores on Sensation Seeking. Further research is recommended that measures actual sensitivity to motion sickness.

    The Internet is a major source of health information but most seekers are not familiar with medical vocabularies. Hence, their searches fail due to bad query formulation. Several methods have been proposed to improve information retrieval: query expansion, syntactic and semantic techniques or knowledge-based methods. However, it would be useful to clean those queries which are misspelled. In this paper, we propose a simple yet efficient method in order to correct misspellings of queries submitted by health information seekers to a medical online search tool. In addition to query normalizations and exact phonetic term matching, we tested two approximate string comparators: the similarity score function of Stoilos and the normalized Levenshtein edit distance. We propose here to combine them to increase the number of matched medical terms in French. We first took a sample of query logs to determine the thresholds and processing times. In the second run, at a greater scale we tested different combinations of query normalizations before or after misspelling correction with the retained thresholds in the first run. According to the total number of suggestions (around 163, the number of the first sample of queries), at a threshold comparator score of 0.3, the normalized Levenshtein edit distance gave the highest F-Measure (88.15%) and at a threshold comparator score of 0.7, the Stoilos function gave the highest F-Measure (84.31%). By combining Levenshtein and Stoilos, the highest F-Measure (80.28%) is obtained with 0.2 and 0.7 thresholds respectively. However, queries are composed by several terms that may be combination of medical terms. The process of query normalization and segmentation is thus required. The highest F-Measure (64.18%) is obtained when this process is realized before spelling-correction. Despite the widely known high performance of the normalized edit distance of Levenshtein, we show in this paper that its combination with the Stoilos algorithm improved

    To document physical health problems that asylum seekers experience on settlement in the community and to assess their utilisation of healthcare services and barriers to care, in an international context. A systematic review of quantitative and qualitative studies was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. MEDLINE, PsycINFO, Embase and CINAHL databases were searched from 2002 to October 2012, focusing on adult asylum seekers residing in the community in high-income countries. The search yielded 1499 articles, of which 32 studies met the inclusion criteria - 23 quantitative and nine qualitative. Asylum seekers had complex health profiles spanning a range of infectious diseases, chronic non-communicable conditions, and reproductive-health issues. They appeared to utilise health services at a higher rate than the host population, yet faced significant barriers to care. The findings of this study highlight the health inequities faced by asylum seekers residing in the communities of host countries, internationally. National data on asylum seekers' health profiles, service utilisation and barriers to care, as well as cross-country policy comparisons, are urgently required for the development of effective Australian health programs and evidence-based policy. What is known about the topic? The clinical and political focus of asylum seekers' health has largely been on the higher incidence of mental disorders and the impact of immigration detention. Since policy changes made in late 2011, an increasing number of asylum seekers have been permitted to live in the community while their claims are processed. There is a paucity of research exploring the physical health needs of asylum seekers residing in the community. What does this paper add? The international literature highlights the complexity of asylum seekers' health profiles. Although they appear to utilise health services at a higher rate than the host population

    Background Although acupuncture sensation (also known as de qi) is a cornerstone of traditional acupuncture therapy, most research has accepted the traditional method of defining acupuncture sensation only through subjective patient reports rather than on any quantifiable physiological basis. Purpose To preliminarily investigate the frequency of key sensations experienced while needling to specific, quantifiable tissue levels (TLs) guided by ultrasound (US) imaging. Methods Five participants received needling at two acupuncture points and two control points at four TLs. US scans were used to determine when each TL was reached. Each volunteer completed 32 sets of modified Southampton Needle Sensation Questionnaires. Part one of the study tested sensations experienced at each TL and part two compared the effect of oscillation alone versus oscillation + rotation. Results In all volunteers, the frequency of pricking, sharp sensations was significantly greater in shallower TLs than deeper (p=0.007); the frequency of sensations described as deep, dull and heavy, as spreading, and as electric shocks was significantly greater in deeper TLs than shallower (p=0.002). Sensations experienced did not significantly differ between real and control points within each of three TLs (p>0.05) except TL 4 (p=0.006). The introduction of needle rotation significantly increased deep, dull, heavy sensations, but not pricking and sharp sensations; within each level, the spectrum of sensation experienced during both oscillation + rotation and oscillation alone did not significantly differ between acupuncture and control points. Conclusion The preliminary study indicates a strong connection between acupuncture sensation and both tissue depth and needle rotation. Furthermore, the new methodology has been proven feasible. A further study with an objective measurement is warranted. PMID:21642648

    Purpose People frequently present to voice clinics with complaints of irritating laryngeal sensations. Clinicians attempt to reduce the irritating sensations and their common sequela, coughing and throat clearing, by advocating for techniques that remove the irritation with less harm to the vocal fold tissue. Despite the prevalence of patients with these complaints, it is not known if the less harmful techniques recommended by clinicians are effective at clearing irritating laryngeal sensations or that irritating laryngeal sensations are, in fact, more frequent in people with voice disorders than people without voice disorders. Method Assessments of participant reported laryngeal sensation, pre- and post- clearing task, were obtained from 22 people with and 24 people without a voice disorder. Six clearing tasks were used to preliminarily evaluate the differing effects of tasks believed to be deleterious and ameliorative. Results People with and without voice disorders reported pre-clear laryngeal sensation at a similar rate. Post-clear sensation was less likely to be completely or partially removed in people with voice disorders than in the non-voice disordered group. Hard throat clear and swallow with water were the most effective techniques at removing laryngeal sensation. Conclusions The findings provide initial evidence for some of the clinical practices common to treating patients with voice disorders and chronic clearing such as advocating for swallowing a sip of water as a replacement behavior instead of coughing or throat clearing. However, the findings raise questions about other practices such as associating irritating laryngeal sensation with a voice disorder. PMID:22717491

    Full Text Available Sensation seeking is a personality trait that has been associated with disinhibited behaviours including substance use and gambling, but also with high-risk sport practices including skydiving, paragliding, and downhill skiing. Twin studies have shown that sensation seeking is moderately heritable, and candidate genes encoding components involved in dopaminergic transmission have been investigated as contributing to this type of behaviour. To determine whether variants in the regulatory regions of the dopamine-4-receptor gene (DRD4 influenced sport-specific sensation seeking, we analyzed five polymorphisms (-1106T/C, -906T/C, -809G/A, -291C/T, 120-bp duplication in the promoter region of the gene in a cohort of skiers and snowboarders (n = 599 that represented a broad range of sensation seeking behaviours. We grouped subjects by genotype at each of the five loci and compared impulsive sensation seeking and domain-specific (skiing sensation seeking between groups. There were no significant associations between genotype(s and general or domain-specific sensation seeking in the skiers and snowboarders, suggesting that while DRD4 has previously been implicated in sensation seeking, the promoter variants investigated in this study do not contribute to sensation seeking in this athlete population.

    Full Text Available Abstract Background About 80% of new tuberculosis cases in Norway occur among immigrants from high incidence countries. On arrival to the country all asylum seekers are screened with Mantoux test and chest x-ray aimed to identify cases of active tuberculosis and, in the case of latent tuberculosis, to offer follow-up or prophylactic treatment. We assessed a national programme for screening, treatment and follow-up of tuberculosis infection and disease in a cohort of asylum seekers. Methods Asylum seekers ≥ 18 years who arrived at the National Reception Centre from January 2005 to June 2006, were included as the total cohort. Those with a Mantoux test ≥ 6 mm or positive x-ray findings were included in a study group for follow-up. Data were collected from public health authorities in the municipality to where the asylum seekers had moved, and from hospital based internists in case they had been referred to specialist care. Individual subjects included in the study group were matched with the Norwegian National Tuberculosis Register which receive reports of everybody diagnosed with active tuberculosis, or who had started treatment for latent tuberculosis. Results The total cohort included 4643 adult asylum seekers and 97.5% had a valid Mantoux test. At least one inclusion criterion was fulfilled by 2237 persons. By end 2007 municipal public health authorities had assessed 758 (34% of them. Altogether 328 persons had been seen by an internist. Of 314 individuals with positive x-rays, 194 (62% had seen an internist, while 86 of 568 with Mantoux ≥ 15, but negative x-rays (16% were also seen by an internist. By December 31st 2006, 23 patients were diagnosed with tuberculosis (prevalence 1028/100 000 and another 11 were treated for latent infection. Conclusion The coverage of screening was satisfactory, but fewer subjects than could have been expected from the national guidelines were followed up in the community and referred to an internist.

    This paper will highlight one of the key findings of a qualitative study based on the analysis of in-depth interviews with 14 health visitors describing their experiences working with refugees and asylum seekers. Despite changes in government legislation to improve children's services in order to prevent harm to children, this recent study demonstrated that health visitors were working with the complexities of needs among refugees and asylum seekers related to safeguarding both children and vulnerable women. The health visitors often worked with families and individuals with no support from other professional services, they worked with failed asylum seekers who were unable to access other forms of support and they worked with women and children who were caught in a cycle of domestic abuse due to their immigration status. They were also working with families who would disappear from the systems in place to safeguard children.

    Asylum seekers are a unique population, particularly those who have endured persecution for their sexual orientation or gender identity. Little data exist about the specific experiences and needs of asylum seekers persecuted due to lesbian, gay, bisexual, or transgender (LGBT) identity. Quantitative data were gathered regarding demographics, persecution histories, and mental health of 61 clients from a torture survivors program in New York City who reported persecution due to LGBT identity. Thirty-five clients persecuted due to their LGBT identity were matched by country of origin and sex with clients persecuted for other reasons to explore how persecution and symptoms may differ for LGBT clients. LGBT asylum seekers have a higher incidence of sexual violence, persecution occurring during childhood, persecution by family members, and suicidal ideation. Understanding the type of persecution experiences and how these influence mental health outcomes is an essential step toward designing and delivering effective treatments.

    Violence in Mexico rose sharply in response to President Felipe Calderón’s military campaign against drug cartels which began in late 2006. As a consequence, the number of Mexicans who have sought asylum in the United States has grown significantly. In 2013, Mexicans made up the second largest group of defensive asylum seekers (those in removal proceedings) in the United States, behind only China (EOIR 2014b). Yet between 2008 and 2013, the grant rate for Mexican asylum seekers in immigration...

  15. Sensation seeking as risk factor for suicidal ideation and suicide attempts in adolescence.

    High sensation seeking in adolescence is associated with engagement in risk-taking behaviors, especially substance use. Although depressed adolescents are prone to increased risk-taking, and suicidal behavior can be considered within the spectrum of risk-taking behaviors, the relationships between sensation seeking, depression, and suicidal behavior have not been explored. A self-report questionnaire assessing sensation seeking, depression, substance use problems, and suicidal ideation and suicide attempts was completed by 9th- through 12th-grade students (n=2189) in six New York State high-schools from 2002 through 2004. Logistic regression analyses were conducted to examine main and interaction effects between sensation seeking and the four clinical variables. High sensation seeking was positively associated with depressive symptoms and substance use problems. The main effects of sensation seeking on suicidal ideation and suicide attempts remained significant after controlling for depression and substance use. The association between sensation seeking and suicide attempts was moderated by substance use problems. The schools were suburban and predominantly white, limiting the generalizability of the results. Other mental disorders with potential implications for sensation seeking and for suicidal behavior, such as bipolar disorders, were not assessed. The finding that sensation seeking makes an independent contribution to the risk of suicidal ideation and attempts is consistent with findings in literature on novelty seeking and impulsivity. The associations between sensation seeking, depressive symptoms and suicidal behavior may be compatible with the presence of an underlying temperamental dysregulation. Screening for sensation seeking may contribute to the reduction of adolescent suicide risk. Copyright © 2012 Elsevier B.V. All rights reserved.

    To evaluate the reproducibility of bladder sensation during standardized filling cystometry in female volunteers and overactive bladder (OAB) patients, repeated with weekly interval. We recruited 13 female nulliparous volunteers (age 21-47) and 17 female patients with OAB between (age 18-72). They participated in three investigation periods, each separated by 7 days to assess reproducibility of sensation related to standardized cystometry. Subjects were asked to report all sensations they felt during bladder filling. The previously described pattern of sensation was reported during bladder filling in all. Consecutive sensations corresponded to statistically higher bladder volumes. Volumes, at which different sensations of bladder filling were reported, were significantly higher in controls than in OAB patients [first sensation of filling (FSF) P = 0.003, first desire to void (FDV) P sensation/volume ratios were significantly higher in patients with OAB than in the healthy volunteers: FSF occurred at mean 46% and FDV at mean 73% of SDV in OAB patients, compared to 36% and 64% in healthy volunteers. Sensations proved highly reproducible when determined with weekly interval. Our data demonstrate that cystometric filling sensation determined in a standardized way with weekly interval is highly reproducible in healthy and in OAB patients. This finding has, in our opinion, clinical importance as it shows that the technique is reliable both for a sensory evaluation of the LUT as to study influence of treatment aimed at changing this sensation.

    Scales are widely used to assess the personal experience of thermal conditions in built environments. Most commonly, thermal sensation is assessed, mainly to determine whether a particular thermal condition is comfortable for individuals. A seven-point thermal sensation scale has been used...... extensively, which is suitable for describing a one-dimensional relationship between physical parameters of indoor environments and subjective thermal sensation. However, human thermal comfort is not merely a physiological but also a psychological phenomenon. Thus, it should be investigated how scales for its...... assessment could benefit from a multidimensional conceptualization. The common assumptions related to the usage of thermal sensation scales are challenged, empirically supported by two analyses. These analyses show that the relationship between temperature and subjective thermal sensation is non...

    Sensation seeking is a personality trait that is robustly correlated with delinquent behavior in adolescence. The current study tested specific contextual factors hypothesized to facilitate, exacerbate or attenuate this risk factor for adolescent delinquency. Individual differences in sensation seeking, peer deviance, parental monitoring and self-reported delinquent behavior were assessed in a sample of 470 adolescents. Peer deviance partially mediated the effects of sensation seeking and parental monitoring on adolescent delinquency. We also found evidence for a three-way interaction between sensation seeking, peer deviance and parental monitoring, such that the highest rates of delinquency occurred from the concurrence of high sensation seeking, high peer deviance, and low levels of parental monitoring. Results highlight the importance of considering peer- and family-level processes when evaluating personality risk and problematic adolescent behavior.

    To examine prospectively the trajectory of trauma-related psychiatric symptoms and disability amongst asylum seekers over the course of the refugee determination process. To identify the direct impact of the refugee decision on psychiatric symptoms by adjusting for other variables, namely sociodemographic characteristics, past trauma, and ongoing postmigration stresses. A prospective cohort study of asylum seekers recruited from a random sample of immigration agents in Sydney, Australia. Consecutive asylum seekers were referred for interview by immigration agents. Interviews were undertaken after the initial application and on average, 3.8 months after the refugee decision. Measures assessed premigration trauma and postmigration stressors. Mental health status was assessed using the Harvard Trauma Questionnaire and the Hopkins Symptom Checklist-25. Functional impairment was assessed with the Medical Outcomes Study-Short Form 12. Sixty-two of 73 asylum seekers were retained at follow-up. The accepted (16) and rejected (46) groups did not differ on premigration trauma or baseline psychiatric symptoms. Postdecision, the accepted group showed substantial improvements in posttraumatic stress disorder, anxiety, depression, and in mental health functioning, whereas the rejected group maintained high levels of symptoms on all psychiatric indices. Establishing secure residency status for asylum seekers may be important to their recovery from trauma-related psychiatric symptoms. The practical and theoretical implications are discussed.

    Full Text Available Abstract Background Asylum procedures are known to be protracted, stretching to over ten years in many host countries. International research shows high levels of distress for asylum seekers. Little is known about actual psychiatric morbidity in this population, especially during the first few years postmigration. Methods The mental health status of two groups of asylum seekers was assessed: Group 1 (n = 43 had arrived in Switzerland 2.9 (SD 1.1 months prior to assessment, while Group 2 (n = 43 had arrived 15.5 (SD 3.2 months prior to assessment. Psychiatric disorders were diagnosed using the Mini International Neuropsychiatric Interview (MINI. Symptom severity of posttraumatic stress disorder (Posttraumatic Diagnostic Scale, anxiety (Hopkins Symptom Checklist, depression (Hopkins Symptom Checklist, and pain (Verbal Rating Scale were assessed using self-report questionnaires. Postmigratory factors such as German language proficiency and social contacts were also assessed. Interviews were conducted with the assistance of trained interpreters. Results Four out of ten participants met diagnostic criteria for at least one DSM-IV disorder. Groups did not differ with respect to psychiatric morbidity or symptom levels. Major depression (31.4% and PTSD (23.3% were diagnosed most frequently. The number of experienced traumatic event types was highly correlated with psychiatric morbidity. Conclusions Psychiatric morbidity in asylum seekers in the first two years after arrival is high, with no indication of a decrease in mental distress over time. Traumatic experiences seem to play a major role in morbidity during this time. Considering the magnitude of clinically relevant distress, a short psychological screening upon arrival with a focus on traumatic experiences may be warranted.

    Fair, Genevieve L; Harris, Mark F; Smith, Mitchell M

    2018-03-15

    Transition of asylum seekers from special-purpose health services to mainstream primary care is both necessary and difficult. This study explores the issues encountered by asylum seekers undergoing this transition in Sydney, Australia. Qualitative semistructured interviews were conducted with nine asylum seeker patients and nine staff working in the sector. Asylum seekers faced significant challenges in the transition to mainstream primary care. Contributing factors included the complexity of health and immigration systems, the way in which asylum seeker-specific services provide care, lack of understanding and accommodation by mainstream general practioner (GP) services, asylum seekers' own lack of understanding of the health system, mental illness, and social and financial pressures. There is a need for better preparation of asylum seekers for the transition to mainstream primary care. Mainstream GPs and other providers need more education and support so that they can better accommodate the needs of asylum seeker patients. This is an important role for Australia's refugee health services and Primary Health Networks.

    Full Text Available Forced displacement related to persecution and violent conflict has reached a new peak in recent years. The primary aim of this study is to provide an initial overview of the acute and chronic health care problems of asylum seekers from the Middle East, with special emphasis on asylum seekers from Syria.Our retrospective data analysis comprised adult patients presenting to our emergency department between 01.11.2011 and 30.06.2014 with the official resident status of an "asylum seeker" or "refugee" from the Middle East.In total, 880 patients were included in the study. Of these, 625 (71.0% were male and 255 (29.0% female. The median age was 34 (range 16-84. 222 (25.2% of our patients were from Syria. The most common reason for presentation was surgical (381, 43.3%, followed by medical (321, 36.5% and psychiatric (137, 15.6%. In patients with surgical presentations, trauma-related problems were most common (n = 196, 50.6%. Within the group of patients with medical presentation, acute infectious diseases were most common (n = 141, 43.9%, followed by neurological problems (n = 70, 21.8% and gastrointestinal problems (n = 47, 14.6%. There were no differences between Syrian and non-Syrian refugees concerning surgical or medical admissions. The most common chronic disorder of unclear significance was chronic gastrointestinal problems (n = 132, 15%, followed by chronic musculoskeletal problems (n = 108, 12.3% and chronic headaches (n = 78, 8.9%. Patients from Syria were significantly younger and more often suffered from a post-traumatic stress disorder than patients of other nationalities (p<0.0001, and p = 0.05, respectively.Overall a remarkable number of our very young group of patients suffered from psychiatric disorders and unspecified somatic symptoms. Asylum seekers should be carefully evaluated when presenting to a medical facility and physicians should be aware of the high incidence of unspecified somatic symptoms in this patient population

    2009-09-01

    We performed a prospective multicomponent study to determine whether subjective and objective bladder sensation instruments may provide data on sensory dysfunction in patients with overactive bladder. We evaluated 70 prospectively enrolled patients with urodynamics and questionnaires on validated urgency (Urgency Perception Score), general overactive bladder (Urogenital Distress Inventory) and quality of life (Incontinence Impact Questionnaire). We first sought a correlation between sensory specific (Urgency Perception Score) and quality of life questionnaire scores. We then assessed a correlation between sensory questionnaire scores and urodynamic variables, exploring the hypothesis that certain urodynamic parameters may be bladder sensation measures. We evaluated 2 urodynamic derivatives (first sensation ratio and bladder urgency velocity) to increase sensory finding discrimination. We noted a moderate correlation between the Urgency Perception Score (0.56) and the Urogenital Distress Inventory (0.74) vs the Incontinence Impact Questionnaire (each p Perception Score and bladder capacity (-0.25, p sensation ratio and bladder urgency velocity statistically significantly correlated with the Urgency Perception Score despite the lesser or absent correlation associated with the individual components of these derivatives. Bladder sensation questionnaires may be valuable to identify patients with sensory dysfunction and provide additional data not obtained in generalized symptom questionnaires. Urodynamic variables correlated with bladder sensation questionnaire scores and may be an objective method to assess sensory dysfunction.

    Sensation is commonly impaired immediately post-stroke but little is known about the long-term changes in cutaneous sensation that have the capacity to adversely impact independence and motor-function. We investigated cutaneous sensory thresholds across the hand in the chronic post-stroke period. Cutaneous sensation was assessed in 42 community-dwelling stroke patients and compared to 36 healthy subjects. Sensation was tested with calibrated monofilaments at 6 sites on the hand that covered the median, ulnar and radial innervation territories and included both glabrous (hairless) and hairy skin. The motor-function of stroke patients was assessed with the Wolf Motor Function Test and the upper-limb motor Fugl-Meyer Assessment. Impaired cutaneous sensation was defined as monofilament thresholds >3 SD above the mean of healthy subjects and good sensation was ≤ 3 SD. Cutaneous sensation was impaired for 33% of patients and was 40-84% worse on the more-affected side compared to healthy subjects depending on the site (psensation fell within the healthy range, although ∼ 1/3 of patients were classified with impaired sensation. Classification by motor-function revealed low levels of impaired sensation. The magnitude of sensory loss was only apparent when the sensory-function of stroke patients was classified as good or impaired. Sensation was most impaired on the dorsum of the hand where age-related changes in monofilament thresholds are minimal in healthy subjects. Although patients with both high and low motor-function had poor cutaneous sensation, overall patients with low motor-function had poorer cutaneous sensation than those with higher motor-function, and relationships were found between motor impairments and sensation at the fingertip and palm. These results emphasize the importance of identifying the presence and magnitude of cutaneous sensory impairments in the chronic period after stroke.

    Full Text Available PRINCIPALS: Over the last two decades, the total annual number of applications for asylum in the countries of the European Union has increased from 15,000 to more than 300,000 people. The aim of this study was to give a first overview on multimorbidity of adult asylum seekers. METHODS: Our retrospective Swiss single center data analysis examined multimorbidity of adult asylums seekers admitted to our ED between 1 January 2000 and 31 December 2012. RESULTS: A total of 3170 patients were eligible for the study; they were predominantly male (2392 male, 75.5% versus 778 female, 24.5. The median age of the patients was 28 years (range 28-82. The most common region of origin was Africa (1544, 48.7%, followed by the Middle East (736, 23.6%. 2144 (67.6% of all patients were not multimorbid. A total of 1183 (37.7% of our patients were multimorbid. The mean Charlson comorbidity index was 0.25 (SD 1.1, range 0-12. 634 (20% of all patients sufferem from psychiatric diseases, followed by chronic medical conditions (12.6%, 399 and infectious diseases (4.7%, 150. Overall, 11% (349 of our patients presented as a direct consequence of prior violence. Patients from Sri Lanka/India most often suffered from addictions problems (50/240, 20.8%, p<0.0001. Infectious diseases were most frequent in patients from Africa (6.6%, followed by the Balkans and Eastern Europe/Russia (each 3.8%. CONCLUSION: The health care problems of asylum seekers are manifold. More than 60% of the study population assessed in our study did not suffer from more than one disease. Nevertheless a significant percentage of asylum seekers is multimorbid and exhibits underlying psychiatric, infectious or chronic medical conditions despite their young age.

    Full Text Available According to the United Nations High Commissioner for Refugees (UNHCR, nowadays, 65,3 million individuals have been forcibly displaced worldwide. In Europe, Italy is one of the countries with the highest number of asylum seeker arrivals per year and the emergency nature of the present-day migratory flows are increasingly involving researchers and clinicians to come up with and develop new models of research and interventions. This article aims to conduct a review of the Italian psychological research in the field of forced migration in order to systematise the Italian studies, to compare the Italian situation with the international one and to define limits, resources and future directions of current Italian research. A literature review in the databases Scopus, PubMed and Web of Knowledge for documents published from 2012 to 2017 was conducted. From the analysis, twelve articles emerged principally following two main trajectories of investigation: a clinical and mental health-related trajectory and a psychosocial and community-based one. Compared with the wider international field of research, a general underdevelopment of Italian research emerged. Research into protective factors with regard to the development of psychopathological outcomes and on interventions is highly recommended. Results highlighted support for future research on the theme of asylum seekers and refugees. Some cause for reflection as regards levels of criticality, the direction of future research and specific links between research and Italian social policies were given.

  15. Forensic dental investigations and age assessment of asylum seekers.

    2008-06-01

    Age estimation is useful in forensic investigations to aid in the process of identifying unknown victims as well as living individuals. In many countries age estimation is commonly used to assist immigration authorities in deciding whether refugees or illegal migrants have reached that designated age that separates a juvenile from an adult. This is particularly important for the protection of unaccompanied minors. Italy is a country of great appeal for immigration as people from other Mediterranean countries can easily reach Italian coasts. In Italy, as in other western world countries, unaccompanied asylum seekers deemed to be under 18 face a very different path through the immigration system. They cannot be deported and are sent through a juvenile system where they have access to education programmes and may be granted a residence permit. The Section of Legal Medicine of the University of Bari was approached by Judges and Immigration Police with the question to assess the age of unaccompanied asylum seekers who claim to be below 18 years of age. The contribution of forensic odontologists for age estimation was recognised and since November 2006 age estimation of asylum seekers in Bari (Italy) relies on clinical and dental examination together with skeletal maturation as seen on radiographs of the left hand and wrist, the pelvis for iliac crests and root development and mineralisation of third molars as seen on an orthopantomogram.

    2011-01-01

    Full Text Available One popular Community question answering (CQA site, Yahoo! Answers, had attracted 120 million users worldwide, and had 400 million answers to questions available. A typical characteristic of such sites is that they allow anyone to post or answer any questions on any subject. Question Answering Community has emerged as popular, and often effective, means of information seeking on the web. By posting questions, for other participants to answer, information seekers can obtain specific answers to their questions. However, CQA is not always effective: in some cases, a user may obtain a perfect answer within minutes, and in others it may require hours and sometimes days until a satisfactory answer is contributed. We investigate the problem of predicting information seeker satisfaction in yahoo collaborative question answering communities, where we attempt to predict whether a question author will be satisfied with the answers submitted by the community participants. Our experimental results, obtained from a large scale evaluation over thousands of real questions and user ratings, demonstrate the feasibility of modeling and predicting asker satisfaction. We complement our results with a thorough investigation of the interactions and information seeking patterns in question answering communities that correlate with information seeker satisfaction. We also explore automatic ranking, creating abstract from retrieved answers, and history updation, which aims to provide users with what they want or need without explicitly ask them for user satisfaction. Our system could be useful for a variety of applications, such as answer selection, user feedback analysis, and ranking.

    Sensation is a neglected aspect of the outcome of breast reconstructions with implants. The aim of this prospective study was to evaluate the cutaneous somatosensory status in breasts following mastectomy and immediate reconstruction with permanent adjustable prostheses and to analyze the patients' subjective experience of the sensation. Twenty-four consecutive patients diagnosed with invasive or in situ breast carcinoma were examined preoperatively and 2 years after mastectomy and reconstruction, for assessment of perception thresholds for touch, cold, warmth, and heat pain above and below the areola. Von Frey filaments and a Peltier element-based thermode were used. The patients completed a questionnaire concerning their experienced sensation in the reconstructed breast. Using quantitative somato-sensory testing, the sensation to all the examined modalities was significantly impaired compared to preoperatively. Most affected was the area above the areola. Patients given postoperative radiotherapy (n = 9) did not differ from those without radiotherapy (n = 15) regarding any of the modalities. All patients reported reduced sensation in the reconstructed breast compared to that preoperatively. Twenty-three patients stated that the reconstructed breast felt different from the other breast; nevertheless 16 reported that the reconstructed breast felt like a real breast. The study revealed sensation impairment following mastectomy and immediate reconstruction with implants. Patients should be informed about this effect preoperatively to allow adequate expectations regarding the sensation outcome. However, two-thirds of the study patients considered that the reconstructed breast felt like a real breast, which must be one of the main purposes of a breast reconstruction.

    BACKGROUND: Refugees and asylum seekers experience language barriers in general practice. Qualitative studies have found that responses to language barriers in general practice are ad hoc with use of both professional interpreters and informal interpreters (patients\\' relatives or friends). However, the scale of the issues involved is unknown. This study quantifies the need for language assistance in general practice consultations and examines the experience of, and satisfaction with, methods of language assistance utilized. METHODS: Data were collected by telephone survey with general practitioners in a regional health authority in Ireland between July-August 2004. Each respondent was asked a series of questions about consulting with refugees and asylum seekers, the need for language assistance and the kind of language assistance used. RESULTS: There was a 70% (n = 56\\/80) response rate to the telephone survey. The majority of respondents (77%) said that they had experienced consultations with refugees and asylum seekers in which language assistance was required. Despite this, general practitioners in the majority of cases managed without an interpreter or used informal methods of interpretation. In fact, when given a choice general practitioners would more often choose informal over professional methods of interpretation despite the fact that confidentiality was a significant concern. CONCLUSION: The need for language assistance in consultations with refugees and asylum seekers in Irish general practice is high. General practitioners rely on informal responses. It is necessary to improve knowledge about the organisational contexts that shape general practitioners responses. We also recommend dialogue between general practitioners, patients and interpreters about the relative merits of informal and professional methods of interpretation so that general practitioners\\' choices are responsive to the needs of patients with limited English.

    To synthesize the recent qualitative literature and identify the integrative themes describing the parenthood experiences of refugees, asylum-seekers and undocumented migrants. We searched seven online databases for the period January 2006 to February 2017. We included English and French published peer-reviewed articles and graduate-level dissertations, which qualitatively examined the parenthood experiences of refugees, asylum-seekers and undocumented migrants. We summarized study characteristics and performed a thematic analysis across the studies. One hundred thirty eight studies met inclusion criteria. All but three were conducted in high-income countries, mainly in the US. Migrants studied were mostly undocumented from Latin America and refugees from Sub-Saharan Africa. Almost all studies (93%) included mothers; about half (47%) included fathers; very few (5%) included extended family members. We identified three integrative themes: 1) experiencing hardship and/or loss in the context of precarious migration and past traumas; 2) building resilience and strength by bridging language, norms and expectations; and 3) living transnationally: obligations, challenges and resources. Each theme contributed to shaping the parenthood experience; the transnationalism theme intersected with the themes on hardship and loss and resilience and strength. More research is needed with fathers, extended family members, asylum-seekers and in the LMIC context. A transnational lens needs to be applied to programs, policies and future research for refugee, asylum-seeker and undocumented migrant parents. Addressing transnational concerns (family separation and reunification), acknowledging transnational resources, fostering a transnational family identity and conducting transnational and longitudinal studies are potentially pivotal approaches for this sub-population of parents.

    Surface electrical stimulation (SES) is being investigated as a noninvasive method to evoke natural sensations distal to electrode location. This may improve treatment for phantom limb pain as well as provide an alternative method to deliver sensory feedback. The median and/or ulnar nerves of 35 subjects were stimulated at the elbow using surface electrodes. Strength-duration curves of hand sensation were found for each subject. All subjects experienced sensation in their hand, which was mostly described as a paresthesia-like sensation. The rheobase and chronaxie values were found to be lower for the median nerve than the ulnar nerve, with no significant difference between sexes. Repeated sessions with the same subject resulted in sufficient variability to suggest that recalculating the strength-duration curve for each electrode placement is necessary. Most of the recruitment curves in this study were generated with 28 to 36 data points. To quickly reproduce these curves with limited increase in error, we recommend 10 data points. Future studies will focus on obtaining different sensations using SES with the strength-duration curve defining the threshold of the effective parameter space.

    Procedures for determining refugee status across Europe are being speeded up, despite the high prevalence of mental health difficulties among asylum seekers. An assurance given is that ''vulnerable applicants'' will be identified and excluded from accelerated procedures. Although experts have recommended assessments to be undertaken by experienced clinicians, this is unlikely to happen for political and financial reasons. Understanding how non-clinically qualified personnel perform assessments of mental health issues is timely and crucial. Misrecognition of refugees due to the inappropriate use of accelerated procedures involves the risk of returning the very people who have the right to protection from further persecution. To examine the decision making of immigration lawyers, who are an example of a group of nonclinicians who decide when and whether to refer asylum-seekers for psychiatric assessment. Semi-structured interviews were conducted with 12 legal representatives working with people seeking refugee or human rights protection in the United Kingdom. The resultant material was analysed using Framework Analysis. Themes clustered around the legal case, the client, the representative and the systems, all with sub-themes. A mapping exercise integrated these themes to show how representatives brought together questions of (1) evidential reasons for a report, influenced by their legal, psychological and case law knowledge, and (2) perceived evidence of mental distress, influenced by professional and personal experiences and expectations. The legal representatives interviewed were well-informed and trained in psychological issues as well as clearly dedicated to their clients. This helped them to attempt quasi-diagnoses of common mental health problems. They nonetheless demonstrated stereotypical understanding of post-traumatic stress disorder and other possible diagnoses and the role of subjectivity. The study has implications for other groups - particularly those

  2. Multimodal mechanisms of food creaminess sensation.

    In this work, the sensory creaminess of a set of four viscosity-matched fluid foods (single cream, evaporated milk, corn starch solution, and corn starch solution containing long chain free fatty acids) was tested by a panel of 16 assessors via controlled sensation mechanisms of smell only, taste only, taste and tactile, and integrated multimodal. It was found that all sensation channels were able to discriminate between creamy and non-creamy foods, but only the multimodal method gave creaminess ratings in agreement with the samples' fat content. Results from this study show that the presence of long chain free fatty acids has no influence on creaminess perception. It is certain that food creaminess is not a primary sensory property but an integrated sensory perception (or sensory experience) derived from combined sensations of visual, olfactory, gustatory, and tactile cues. Creamy colour, milky flavour, and smooth texture are probably the most important sensory features of food creaminess.

    Full Text Available Abstract The ability to feel hot and cold is critical for animals and human beings to survive in the natural environment. Unlike other sensations, the physiology of cold sensation is mostly unknown. In the present study, we use genetically modified mice that do not express nerve growth factor-inducible B (NGFIB to investigate the possible role of NGFIB in cold sensation. We found that genetic deletion of NGFIB selectively affected behavioral responses to cold stimuli while behavioral responses to noxious heat or mechanical stimuli were normal. Furthermore, behavioral responses remained reduced or blocked in NGFIB knockout mice even after repetitive application of cold stimuli. Our results provide strong evidence that the first transcription factor NGFIB determines the ability of animals to respond to cold stimulation.

    There is a lack of information on how to execute effective searches of the grey literature on refugee and asylum seeker groups for inclusion in systematic reviews. High-quality government reports and other grey literature relevant to refugees may not always be identified in conventional literature searches. During the process of conducting a recent systematic review, we developed a novel strategy for systematically searching international refugee and asylum seeker-related grey literature. The approach targets governmental health departments and statistical agencies, who have considerable access to refugee and asylum seeker populations for research purposes but typically do not publish findings in academic forums. Compared to a conventional grey literature search strategy, our novel technique yielded an eightfold increase in relevant high-quality grey sources that provided valuable content in informing our review. Incorporating a search of the grey literature into systematic reviews of refugee and asylum seeker research is essential to providing a more complete view of the evidence. Our novel strategy offers a practical and feasible method of conducting systematic grey literature searches that may be adaptable to a range of research questions, contexts, and resource constraints.

    Thermal sensation models, capable of predicting human's perception of thermal surroundings, are commonly used to assess given indoor conditions. These models differ in many aspects, such as the number and type of input conditions, the range of conditions in which the models can be applied, and the complexity of equations. Moreover, the models are associated with various thermal sensation scales. In this study, a systematic comparison of seven existing thermal sensation models has been performed with regard to exposures including various air temperatures, clothing thermal insulation, and metabolic rate values after a careful investigation of the models' range of applicability. Thermo-physiological data needed as input for some of the models were obtained from a mathematical model for human physiological responses. The comparison showed differences between models' predictions for the analyzed conditions, mostly higher than typical intersubject differences in votes. Therefore, it can be concluded that the choice of model strongly influences the assessment of indoor spaces. The issue of comparing different thermal sensation scales has also been discussed. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2002-01-01

    Objective To investigate the consistency of autobiographical memory of people seeking asylum, in light of the assumption that discrepancies in asylum seekers' accounts of persecution mean that they are fabricating their stories. Design Repeated interviews. Setting England, 1999 and 2000. Participants Community sample of 27 Kosovan and 12 Bosnian refugees. Main outcome measures Discrepancies in repeated descriptions of one traumatic and one non-traumatic event, including specific details, rated as central or peripheral to the event. Self report measures of post-traumatic stress disorder and depression. Results Discrepancies between an individual's accounts were common. For participants with high levels of post-traumatic stress, the number of discrepancies increased with length of time between interviews. More discrepancies occurred in details peripheral to the account than in details that were central to the account. Conclusion The assumption that inconsistency of recall means that accounts have poor credibility is questionable. Discrepancies are likely to occur in repeated interviews. For refugees showing symptoms of high levels of post-traumatic stress, the length of the application process may also affect the number of discrepancies. Recall of details rated by the interviewee as peripheral to the account is more likely to be inconsistent than recall of details that are central to the account. Thus, such inconsistencies should not be relied on as indicating a lack of credibility. What is already known on this topicDiscrepancies between accounts of an event are often used to judge the credibility of asylum seekersWhat this study addsDiscrepancies arise between two accounts of the same event even when there is no reason for fabricationRefugees with high levels of post-traumatic stress are more likely to give inconsistent accounts if they have a long time to wait between interviewsInterviewees are more likely to be inconsistent in details that they rate as peripheral

    Sober alcoholic abusers exhibit personality traits such as novelty-seeking (NS) and sensation-seeking, which overlap to a limited extent. In parallel, they also show impaired executive and decision-making processes. However, little is known about the specific and common cognitive processes associated with NS and sensation-seeking personality traits in detoxified sober alcoholic abusers. In these present studies, we have investigated the relationships between executive functioning/central executive of working memory (pre-potent response inhibition, manipulation stored in working memory), and decision-making under uncertainty and NS/sensation-seeking traits in such alcoholics. Compared with healthy controls (n = 30, mean age = 40.2), and in agreement with previous studies, alcoholics (n = 30, mean age = 40.4) showed higher levels of both NS and sensation-seeking traits. Alcoholics were also disadvantaged with respect to (a) gambling tasks, as reported previously, and (b) a poor ability to manipulate information stored in working memory and inhibit pre-potent responses. Most importantly, regression analyses and mediation analyses measures showed that poor response inhibition and decision-making were associated with high NS behaviour. In addition, impaired decision-making and manipulation of stored information in working memory were associated with a high sensation-seeking trait. Overall, these results support the existence of specific links between cognitive executive functioning, decision-making under uncertainty and NS/sensation-seeking personality traits in individuals with alcoholism.

    Propagated sensation along the meridian can occur when acupoints are stimulated by acupuncture or electrical impulses. In this study, participants with notable propagated sensation along the dian were given electro-acupuncture at the Jianyu (LI15) acupoint of the large intestine meridian. When participants stated that the sensation reached the back of their hand, regular nervous system action discharge was examined using a physiological recording electrode placed on the superficial branch of the radial nerve. The topographical maps of brain-evoked potential in the primary cortical somatosensory area were also detected. When Guangming (GB37) acupoint in the lower limb and Hegu (LI4) acupoint in the upper limb were stimulated, subjects without propagated sensation along the meridian exhibited a high potential reaction in the corresponding area of the brain cortical so-matosensory area. For subjects with a notable propagated sensation along the meridian, the tion area was larger and extended into the face representative area. These electrophysiological measures directly prove the existence of propagated sensation along the meridian, and the pheral stimulated site is consistent with the corresponding primary cortical somatosensory area, which presents a high potential reaction.

    Young adulthood is a peak period for externalizing behaviors such as substance abuse and antisocial conduct. Evidence from developmental neuroscience suggests that externalizing conduct within this time period may be associated with a "developmental asymmetry" characterized by an early peak in sensation seeking combined with a relatively immature impulse control system. Trait measures of impulsivity-sensation seeking and premeditation-are psychological manifestations of these respective systems, and multiple prior studies suggest that high sensation seeking and low premeditation independently confer risk for distinct forms of externalizing behaviors. The goal of the present study was to test this developmental asymmetry hypothesis, examining whether trait premeditation moderates the effect of sensation seeking on substance use and problems, aggression, and rule-breaking behavior. Using a cross-sectional sample of college-enrolled adults (n = 491), we applied zero-inflated modeling strategies to examine the likelihood and level of risky externalizing behaviors. Results indicated that lower premeditation enhanced the effect of higher sensation seeking on higher levels of positive and negative alcohol consequences, more frequent drug use, and more problematic drug use, but was unrelated to individual differences in antisocial behaviors. Our findings indicate that the developmental asymmetry between sensation seeking and a lack of premeditation is a risk factor for individual differences in problematic substance use among young adults, and may be less applicable for antisocial behaviors among high functioning individuals.

    Full Text Available In a digital world, job seekers prefer to use e-recruitment for a vacancy searching. Thus, the expla- nation of the determinants of their attitude in using this technology is left unobserved. This article reports the result of a survey study on how users utilize e-recruitment to search for works. Three hundred eighty-five just-graduated undergraduate students answered questions regarding their intention of using the e-recruitment under Theory of Acceptance Model. We propose Perceived Use- fulness, Perceived Ease of Use, and Perceived of Enjoyment as the determinants of the job seekers intention. Results showed that those three variables influence the decision making of job seekers. We found also Perceived Usefulness is the mediating effect for jobs seekers in easy-to-use and enjoy feeling. This article provides evidence that e-recruitment has to be friendly user and fun to use to attract job seekers intention.

  4. General habit propensity relates to the sensation seeking subdomain of impulsivity but not obesity

    2016-11-01

    Full Text Available According to dual-system theory, instrumental learning and performance depend on the balance between goal-directed and habitual action control. Overreliance on habits has been argued to characterize clinical conditions such as drug addiction or obsessive-compulsive disorder as well as obesity and excessive impulsivity. A tendency towards habitual action control in obesity has already been indicated in the food domain. However, impairments might not be restricted to eating behavior. This has been suggested by domain-general obesity-associated disturbances in executive function as well as alterations in corticostriatal circuits underlying the goal-directed and habitual systems. In this study we examined the balance of goal-directed and habitual action control in a sample of normal-weight, overweight, and obese participants (n=105 using the slips-of-action test in a non-food context. We tested for continuous or group-based associations between body weight status (BMI and the devaluation sensitivity index (DSI, a parameter representing the balance of the goal-directed and habitual systems in action control. As personality differences in the domain of impulsivity might affect this relationship, we also examined whether the interaction between BMI and self-reported impulsivity, based on the UPPS Impulsive Behavior Scale, was related to the DSI. In addition to that, we tested for direct, i.e., weight status independent, relationships between UPPS subdomains of impulsivity and the DSI. We failed to find evidence for a relationship between weight status and sensitivity to devaluation as indexed by the DSI. However, independent of weight status, we observed lower sensitivity to devaluation in sensation seekers, a subtype of impulsivity. To conclude, behavioral flexibility in the sense of disturbances in the balance between the habitual and goal-directed systems seems to be unaffected by weight status in a non-food context. Consequently, stimuli and

    Full Text Available This study investigated the potential association of impulsiveness and sensation seeking and the attitudes and behaviour characteristic of anorexia and bulimia nervosa in male and female students (between 12 and 20 years. The study had an observational case-control design, in which the case group comprised symptomatic subjects who had scores above the cutoff point designated by the authors for several assessment instruments, and the control group, which comprised asymptomatic participants who had scores below the cutoff point. The study included 300 participants (136 men [45.33%] and 164 women [(54.66%] from Malaga (Spain. All participants received parental authorization to take part in the study. The participants anonymously completed the following self-administered tests: Eating Disorder Inventory (EDI-II, Eating Attitudes Test (EAT-26, Bulimia Test Revised (BULIT-R, Barratt Impulsiveness Scale (BIS-11, and (SSS-V. The results suggest an association between impulsiveness and symptomatology associated with eating disorders, anorexia, and bulimia nervosa. In contrast, sensation seeking was only associated with bulimic symptoms. In summary, the variables impulsivity and sensation seeking appear to be closely associated with eating disorders. Thus, these aspects should be addressed in healthy lifestyle programs, because their inclusion may help to reduce or prevent the increase in eating disorders in the teenage population.

    Objective: To assess the incidence and types of sensation of smell and taste during i.v. injection of five kinds of contrast media (CM) in CT examinations. Methods: 735 patients who underwent contrast-enhanced CT (CE-CT) between 14 March 2016 and 5 April 2016 were enrolled. Medical staff asked patients whether they felt heat sensation and sensation of smell and taste during i.v. injection of CM (one of the following: iopromide, iomeprol, iopamidol, iohexol and ioversol) after their CE-CT. If the patients stated having felt the sensation of smell or taste, they were also asked what kind of smell or taste they sensed. Next, 30 ml of each CM was poured into high-purity pet cups for radiological technologists to smell directly. Radiological technologists were asked whether or not each CM had any smell. Results: The sensations of smell and taste incidence for iopromide were 24.3% and 18.9%, respectively, which were significantly higher than those for other CM (p < 0.05). The highest incidence of the sensation of smell was medicine-ish, and the most frequently noted taste was bitterness. All radiological technologists could directly smell only iopromide, which has an ether group on a side chain and fewer hydroxyl groups. Conclusion: Iopromide showed a higher incidence of sensation of smell and taste than other CM. Advances in knowledge: This was the first investigation of sensation of smell and taste during i.v. injection of CM, and a specific CM showed a higher incidence, which is suspected to be due to its chemical structure.

    In Finland, forensic age assessment is strictly regulated by legislation. According to the Aliens Act (301/2004) and the amendment of the Act (549/2010), the police authorities, the frontier guard authorities, and the immigration authorities have the right to refer asylum seekers to the University of Helsinki, Department of Forensic Medicine, for age assessment. These assessments are especially performed to solve if the person is of major age, the cutoff being 18 completed years. The forensic age assessment is largely based on dental development, since the special permit of the Radiation and Nuclear Safety Authority (STUK) to the Department of Forensic Medicine of the University of Helsinki, allowing the use of ionizing radiation for non-medical purposes, includes dental and hand X-rays. Forensic age assessment is always performed by two forensic odontologists. In 2015, the total number of forensic age assessment examinations was 149, and the countries of origin of the asylum seekers were most commonly Iraq, Afghanistan, and Somalia. The current legislation on forensic age assessment has been well received and approved. Radiological and other examinations can be performed in different parts of Finland, but the forensic odontologist at the University of Helsinki is always involved in the process and ensures joint quality standards for the forensic age assessment.

  8. Contested spacing: International non-profit organizations and the mobility of asylum seekers

    DEFF Research Database (Denmark)

    Albu, Oana Brindusa

    The importance of examining space from an organizational standpoint is timely, not the least because the use of this concept has critical and often unintended social, and political effects (Mengis, Nicolini & Gorli, 2016). The global refugee crisis following the post-2015 Syrian conflict is perhaps...... one indicative situation of the highly contested ways in which international non-profit organizations (INGOs) create spaces for their organizational activities (e.g., build informal settlements to provide emergency aid), and thus affect how individuals (e.g., asylum seekers) get re-settled, confined...... to, or even restricted from living in such spaces. These matters are relevant since in the contexts where both the opportunities to move freely and being at peace are challenged, space is not only a neutral structure in which such contested organizing takes place (Mengis et al., 2016). Rather...

  9. Representation of Refugees, Asylum-Seekers and Refugee Affairs In Hungarian Dailies

    2008-11-01

    Full Text Available How does the press in Hungary write about refugees, asylum-seekers and refugee affairs? We sought to answer this question. Articles appearing in 2005 and 2006 in two leading national Hungarian dailies were examined with quantitative content analysis. The results show that the articles analyzed often treat refugee affairs as an “official” political matter. The high proportion of legislation and political positions conveys the image that refugee affairs are a state or intergovernmental matter, an “official”, legal, political issue rather than for example a humanitarian question. Most of the articles published in both papers write about problems and conflicts in connection with refugee affairs. The negative media image has different significance for different topics. We argue that the question of refugee affairs is a topic where the image shown by the media is of great relevance: the media can be a more important source of information on this subject than personal contacts.

    "Globus sensation" is often described as the sensation of a lump in the throat associated with dry swallowing or the need for dry swallowing, which disappears completely during eating or drinking and for which no organic cause can be established. Due to the uncertain etiology of "globus sensation", it remains difficult to establish standard treatment strategies for affected patients. Lately most attention has been focused on gastroesophageal reflux disease and several reports have indicated that there is a close relationship between esophageal acid reflux and globus sensation. Nowadays, empirical therapy with a high dose of a proton pump inhibitor (PPI) is considered to be indicated for patients with globus sensation, after excluding organic diseases such as pharyngeal cancer, Zenker's diverticulum, or thyroid enlargement. If patients are nonresponsive to PPI therapy, evaluation of esophageal motility should be done. In our recent study, 47.9% had abnormal esophageal motility, with the most common esophageal motility abnormality being an ineffective esophageal motility in PPI-resistant patients with globus sensation. This suggests that prokinetics alone or adding prokinetics to PPI should be the treatment to be considered, although few studies have investigated the efficacy of prokinetics in the treatment of patients with globus sensation. If patients without any esophageal motility dysfunctions are nonresponsive to PPI therapy, either cognitive-behavioral therapy, anti-depressants, or gabapentin could be helpful, although further well-designed, randomized controlled large-scale studies will be necessary to determine the effectiveness of each treatment strategy on patients with globus sensation.

    2003-01-01

    Objective: To determine the changes in sensation of pressure, 2-point discrimination, and submaximal isometric-force production variability due to cryotherapy. Design and Setting: Sensation was assessed using a 2 × 2 × 2 × 3 repeated-measures factorial design, with treatment (ice immersion or control), limb (right or left), digit (finger or thumb), and sensation test time (baseline, posttreatment, or postisometric-force trials) as independent variables. Dependent variables were changes in sensation of pressure and 2-point discrimination. Isometric-force variability was tested with a 2 × 2 × 3 repeated-measures factorial design. Treatment condition (ice immersion or control), limb (right or left), and percentage (10, 25, or 40) of maximal voluntary isometric contraction (MVIC) were the independent variables. The dependent variables were the precision or variability (the standard deviation of mean isometric force) and the accuracy or targeting error (the root mean square error) of the isometric force for each percentage of MVIC. Subjects: Fifteen volunteer college students (8 men, 7 women; age = 22 ± 3 years; mass = 72 ± 21.9 kg; height = 183.4 ± 11.6 cm). Measurements: We measured sensation in the distal palmar aspect of the index finger and thumb. Sensation of pressure and 2-point discrimination were measured before treatment (baseline), after treatment (15 minutes of ice immersion or control), and at the completion of isometric testing (final). Variability (standard deviation of mean isometric force) of the submaximal isometric finger forces was measured by having the subjects exert a pinching force with the thumb and index finger for 30 seconds. Subjects performed the pinching task at the 3 submaximal levels of MVIC (10%, 25%, and 40%), with the order of trials assigned randomly. The subjects were given a target representing the submaximal percentage of MVIC and visual feedback of the force produced as they pinched the testing device. The force exerted

    2015-11-01

    Full Text Available This article is a content analysis of the representation of Syrian asylum seekers in the Turkish press. The research sample includes news reports, columns and visuals published in 2014 in five national newspapers with the highest circulation figures (“Hürriyet”, “Sabah”, “Posta”, “Sözcü”, “Zaman”. The article is part of a larger research project, which is funded by TÜBİTAK, investigating the representation of Syrian asylum seekers between 2011 and 2015 in Turkish newspapers. Analysing news texts and columns is widely held in research projects. However, conducting a visual analysis on news photographs is usually overlooked. This study investigates news texts and news photographs together. The study shows that the coverage of Syrian asylum seekers has usually a positive or neutral content. However, the results also point out the ambivalence in the representations of asylum seekers. The representations of Syrian asylum seekers portray these individuals mostly as “poor” people “in need of help” as well as “threats” for social security. These frequently repeated representations and ambivalence show that the representation of Syrian asylum seekers in Turkish newspapers reproduces the stereotypical representation of asylum seekers as defined in international studies.

  13. Emergency mental health nursing for self-harming refugees and asylum seekers.

    2005-09-01

    This article describes the structure and function of emergency mental health nursing practice for self-harming refugees and asylum seekers on Temporary Protection Visas. Emergency nurses working in accident and emergency departments or as part of crisis intervention teams will see self-harming refugees and asylum seekers at the very point of their distress. This clinical paper is intended to support nurses in their practice should they encounter an adult asylum seeker needing emergency mental health care. Practical strategies are highlighted to help mental health nurses assess, care, and comfort refugees and asylum seekers in this predicament. Mental health nurses should, where possible, work closely with asylum seekers, their support workers, and accredited interpreters and translators to ensure the appropriate use of language when dealing with mental and emotional health issues without further isolating the asylum seeker from appropriate services. To help strengthen continuity and integration of mental health supports for refugees and asylum seekers, well-resourced care must be experienced as coherent and connected. A coherent, interdisciplinary and team-orientated approach will synthesize different viewpoints to shape clinical practice and create workable solutions in local situations.

    Despite a plethora of research on sexual functioning during the past decades, the field is still lacking standardized measurements specifically characterizing orgasm. Although several validated tools are available to assess sexual function in healthy and clinical populations, items on orgasm are limited to frequency or dichotomous responses. A neurophysiologic model of orgasm developed from previous research in able-bodied and spinally injured populations offers a promising framework for the construction of a new questionnaire. To develop and validate a brief self-report measurement of orgasm by the assessment of bodily and physiologic sensations perceived during climax by able-bodied individuals. Although the currently available tool focuses on the phenomenological sensations associated with climax, the goal of this questionnaire was to capture the more specific genital and extragenital sensations associated with orgasm. The current Bodily Sensations of Orgasm questionnaire and the Orgasm Rating Scale. Data from previous research conducted on individuals with spinal cord injury and the available empirical literature provided a pool of 45 items organized into four categories, which were reviewed by an expert panel. Upon review, a 28-item questionnaire was created and administered to a community sample of 227 participants, including men and women, 18 to 73 years old. Exploratory factor analyses supported the four-factor model, in which orgasm is comprised of extragenital sensations, genital sensations and spasms, nociceptive sensations, and sweating responses. Overall, a high degree of internal consistency was found for the final 22-item questionnaire (Cronbach α = 0.87), with individual reliability coefficients showing moderate to high internal consistency (r = 0.65-0.79) for each dimension. Overall temporal stability of the measurement was acceptable (r = 0.74). Using the Orgasm Rating Scale, satisfying convergent validity was confirmed, thereby indicating

    Subjects resting in a 39 C environment were stimulated in different skin regions with a water-cooled thermode. Results indicate that cooling different body regions produces generally equivalent decreases in sweating rate and increases in cold sensation, with the forehead showing a much greater sensitivity per unit area and temperature decrease than other areas. The high thermal sensitivity of the face may have evolved when it was the thinnest-furred area of the body; today's clothing habits have reestablished the importance of the face in the regulation of body temperature.

    Straining at stool is an automatic reflex in babies and implies the presence of rectal sensation. We hypothesised that early reported rectal sensation would predict future continence in children with anorectal anomalies. The aim of this study is to determine if early straining at stool was a useful predictor of future continence in infants born with high anorectal malformations. A retrospective case note review of prospectively collected clinical information was performed with institutional review board approval. All patients with intermediate/high anorectal malformation operated on by a single surgeon from 1984 to 2010 were included. After stoma closure, parents were asked: The responses were noted within the first year of stoma closure and then all patients were followed up until they were at least 3 ½years old and continence could be assessed using the Krickenbeck outcome classification. Data were compared using Fisher's exact test and sensitivity, specificity and positive predictive value (PPV) were calculated. Forty-eight patients were included in the study. Sixteen (33%) were female (12 cloacal malformation, 3 rectovaginal fistula, 1 rectal atresia) and 32 (66%) were male (6 rectovesical fistulae, 22 rectourethral fistulae, 4 no fistula). Median follow-up was 9.7years (range 3.5-17.9). Twenty-one children were noted by their parents to exhibit early straining at stool after stoma closure. Twenty of them achieved long term continence. The sensitivity of early straining as a predictor for long term continence was 77%, specificity 95% and positive predictive value 95%. The presence of early rectal sensation reported by parents is a good predictor of long term continence. This allows more informed discussion with families in the early years of life.

    2007-01-01

    The longstanding question of whether temperature is sensed via separate sensory systems for warmth and cold was investigated by measuring individual differences in perception of nonpainful heating and cooling. Sixty-two subjects gave separate ratings of the intensity of thermal sensations (warmth, cold) and nociceptive sensations (burning/stinging/pricking) produced by cooling (29 degrees C) or heating (37 degrees C) local regions of the forearm. Stimuli were delivered via a 4 x 4 array of 8 mm x 8 mm Peltier thermoelectric modules that enabled test temperatures to be presented sequentially to individual modules or simultaneously to the full array. Stimulation of the full array showed that perception of warmth and cold were highly correlated (Pearson r = 0.83, p sensations produced by the two temperatures were also correlated, but to a lesser degree (r = 0.44), and the associations between nociceptive and thermal sensations (r = 0.35 and 0.22 for 37 and 29 degrees C, respectively) were not significant after correction for multiple statistical tests. Intensity ratings for individual modules indicated that the number of responsive sites out of 16 was a poor predictor of temperature sensations but a significant predictor of nociceptive sensations. The very high correlation between ratings of thermal sensations conflicts with the classical view that warmth and cold are mediated by separate thermal modalities and implies that warm-sensitive and cold-sensitive spinothalamic pathways converge and undergo joint modulation in the central nervous system. Integration of thermal stimulation from the skin and body core within the thermoregulatory system is suggested as the possible source of this convergence.

    Refugees and asylum seekers have high rates of risk factors for mental disorders. In recent years, Australia has experienced a rapid increase in asylum seeker arrivals, creating new challenges for services in areas with high settlement numbers. This paper describes the design, including analytic framework, of a project set in a refugee health service in the state of Victoria, Australia, as part of their response to meeting the mental health needs of their burgeoning local population of refugees and asylum seekers. In order to assist service planning, the primary aim of this study is to determine: 1) an overall estimate of the prevalence of psychiatric disorders; 2) the specific prevalence of post-traumatic stress disorder 3) the perceived need and unmet need for mental health treatment. The secondary aim of the study is to establish matched risk ratios based on an Australian-born matched comparison group from the 2007 National Survey of Mental Health and Well-Being. A cross-sectional survey is used to estimate the prevalence of psychiatric disorders in refugees and asylum seekers attending a local refugee health service. Measures include the Kessler Psychological Distress Scale-10, the Post-Traumatic Stress Disorder-8, the General-practice User's Perceived-need Inventory together with service utilisation questions from the National Survey of Mental Health and Well-Being. Data collected from refugees and asylum seekers (n = 130) is matched to existing data from Australian-born residents drawn from the 2007 National Survey of Mental Health and Well-Being (n = 520) to produce estimates of the risk ratio. The paper describes a prototype for what is possible within regular services seeking to plan for and deliver high quality mental health care to refugees and asylum seekers. A novel project output will be the development and dissemination of an epidemiological methodology to reliably compare mental health status in a relatively small target sample with a matched

    In the course of our routine whole body skeletal imaging - mainly done for metastatic screening - we were often faced with the nonosseous appearance of the polyphosphate-bound technetium /Foszfon/ as the tracer. A Toshiba GCA-901A/SA digital camera has been used in whole body scan mode. The paradoxity of bone-seekers' accumulation in soft tissues leads to the assumption that not only osteoblasts are able to incorporate the radiotracer but also cells in excited phagocytic state, too. Such states can be induced by inflammatory processes-no matter whether sterile or not - accompanied by some increase in local perfusion. Documentative cases of mastopathy, indurative trombo phlebitis, subacute and chronic postoperative wound healing will be shown with quite different imaging intensity. This should call also attention to avoid misinterpretations. (author)

    The first objective for this report was to perform a comprehensive research of industry models currently being used for similar purposes, in order to provide the Center with ideas of what is being done in area by private companies and government agencies. The second objective was to evaluate the use of taxonomies or ontologies to describe and catalog the areas of expertise at GSFC. The creation of a knowledge taxonomy is necessary for information extraction in order for The Expert Seeker to adequately search and find experts in a particular area of expertise. The requirements to develop a taxonomy are: provide minimal descriptive text; have the appropriate level of abstration; facilitate browsing; ease of use and speed of data entry are critical for success; customized to the organization and its culture; extent of knowledge areas; expandable, so new skills could be develop; could be complemented with free text fields to allow users the option to describe their knowledge in detail.

    Asylum seekers and refugees generally have poorer health than the broader Australian population. However, these groups experience a range of barriers to accessing universal health services. Generalist and specialist refugee health services have been established in Australia to improve the health of humanitarian migrant groups. This article describes a refugee health service established in a high-settlement region of Melbourne, Australia, and explores clients' experiences with the service. Client feedback was captured through interviews (n=18) and surveys (n=159). Participants reported high levels of satisfaction with the service, and highlighted the value in having trusting relationships with staff, access to bicultural workers, onsite interpreting services and integrated care. The findings indicate that it is possible to engage asylum seekers and refugees through healthcare delivery that is responsive to the unique needs of this priority population.

    Can different political ideologies explain policy preferences regarding asylum seekers? We focus on attitudes regarding governmental policy towards out-group members and suggest that perceptions of threat help to shape these policy attitudes. Study 1 compared public opinion regarding asylum policy in Israel ( N = 137) and Australia ( N = 138), two countries with restrictive asylum policies and who host a large number of asylum seekers; Study 2, a longitudinal study, was conducted during two different time periods in Israel-before and during the Gaza conflict. Results of both studies showed that threat perceptions of out-group members drive the relationship between conservative political ideologies and support for exclusionary asylum policies among citizens. Perceptions of threat held by members of the host country (the in-group) towards asylum seekers (the out-group) may influence policy formation. The effect of these out-groups threats needs to be critically weighed when considering Israeli and Australian policies towards asylum seekers.

    2012-12-01

    The relationship of circadian typology with personality has been largely studied in adults, but there are few studies exploring such relationship in adolescents. Adolescence has been associated with a greater tendency to eveningness preference, sleeping problems, poorer academic achievement, earlier substance use, or risky behaviors, and it is suggested that this association might be mediated by personality factors. Given the relevance of identifying the behavioral outcomes of young evening types to detect and prevent health problems, the present study aimed to explore, for the first time, the relationship between sensation seeking and circadian typology in an adolescent sample of 688 students (51.45% boys) from 12 to 16 yrs old. They answered the Spanish versions of the Morningness-Eveningness Scale for Children (MESC) and the Junior Sensation Seeking Scale (J-SSS), which includes four subscales measuring Thrill and Adventure Seeking, Experience Seeking, Disinhibition, and Boredom Susceptibility. Analyses showed that boys obtained significantly higher scores than girls on J-SSS total score and all subscales except Boredom Susceptibility, whereas evening-type adolescents of both sexes scored significantly higher than neither types and than morning types on J-SSS total score. These results indicate that evening-type adolescents show a greater desire for varied, new, complex, and intense sensations, and they are ready for experiencing more risks than morning types. The implications of this study suggest the need of being aware of individual differences in the SS trait in evening-type adolescents, as well as taking into account the wide variety of behaviors associated with it, either prosocial or antisocial, to design better preventive health and academic programs.

    This article adopts a genealogical approach in examining Israeli immigration policy by focusing on the situation confronting African asylum seekers who have been forced back into Egypt, detained and deported but who have not had their asylum claims properly assessed. Based on immigration policies formulated at the time of Israeli independence, whose principle objective was to secure a Jewish majority state, we argue that Israel’s treatment of African asylum seekers as ‘infiltrators’/economic ...

  8. Increase in imported malaria in the Netherlands in asylum seekers and VFR travellers.

    Malaria is a notifiable disease in the Netherlands, a non-endemic country. Imported malaria infections occur regularly among travellers, migrants and visitors. Surveillance data were analysed from 2008 to 2015. Trends in amounts of notifications among risk groups were analysed using Poisson regression. For asylum seekers, yearly incidence was calculated per region of origin, using national asylum request statistics as denominator data. For tourists, denominator data were used from travel statistics to estimate incidence per travel region up to 2012. A modest increase in overall imported malaria notifications occurred in 2008-2015 (from 222 in 2008 to 344 in 2015). Notably, in 2014 and 2015 sharp increases were seen in malaria among travellers visiting friends and relatives (VFR), and in asylum seekers. Of all Plasmodium falciparum infections, most (1254/1337; 93.8%) were imported from Africa; 1037/1337 (77.6%) were imported from Central and West Africa. Malaria in VFR was mostly caused by P. falciparum infection after visiting Ghana (22%) or Nigeria (19%). Malaria in asylum seekers was mostly caused by Plasmodium vivax infection from the Horn of Africa. The large number of notifications in asylum seekers resulted from both an increase in number of asylum seekers and a striking increase of malaria incidence in this group. Incidence of malaria in asylum seekers from the Horn of Africa ranged between 0.02 and 0.3% in 2008-2013, but rose to 1.6% in 2014 and 1.3% in 2015. In 2008-2012, incidence in tourists visiting Central and West Africa dropped markedly. Imported malaria is on the rise again in the Netherlands, most notably since 2013. This is mostly due to immigration of asylum seekers from the Horn of Africa. The predominance of P. vivax infection among asylum seekers warrants vigilance in health workers when a migrant presents with fever, as relapses of this type of malaria can occur long after arrival in the Netherlands.

    Understanding the behaviors of surrogate seekers (those who seek health information for others) may guide efforts to improve health information transmission. We used 2011-2012 data from the Health Information National Trends Survey to describe behaviors of online surrogate seekers. Respondents were asked about use of the Internet for surrogate-seeking over the prior 12 months. Data were weighted to calculate population estimates. Two thirds (66.6%) reported surrogate-seeking. Compared to those who sought health information online for only themselves, surrogate seekers were more likely to live in households with others (weighted percent 89.4 vs. 82.5% of self-seekers; p user-generated content: email communication with healthcare providers; visits to social networking sites to read and share about medical topics and participation in online health support groups. On multivariate analysis, those who had looked online for healthcare providers were more likely to be surrogate seekers (OR 1.67, 95% CI 1.08-2.59). In addition to seeking health information, surrogate seekers create and pass along communications that may influence medical care decisions. Research is needed to identify ways to facilitate transmission of accurate health information.

    Full Text Available Objective:This study aimed to determine prevalence of hepatitis B, C and HIV/AIDS in asylum seekers in Istanbul, Turkey. Methods: The data about asylum seekers who applied in Istanbul between March 2008 and March 2010 were evaluated retrospectively. Demographic features and markers of blood borne infections (HBsAg, anti-HCV and anti-HIV results of asylum seekers were reviewed. Results: In total 3043 asylum seekers were included into the study. The leading origin countries of the refugees were from Afghanistan, Turkmenistan and Azerbaijan and majority of them (2328 people, 77% were male. The young adults between 25 and 45 years constituted the most crowded group. Overall prevalence of HCV, HBsAg and HIV/AIDS were 12.2%, 5.9% and 0.7%, respectively. The highest seropositivity rate for anti-HCV, HBsAg and anti-HIV were found in Georgian males (47.1%; in Moldovan males (13.2% and in Somali males (3.1%, respectively. Conclusion:Mostly asylum seekers who have migrated to our country were young adult males from Asia. The highest prevalence rate of HCV was found in Georgian males. Therefore, the increased potential of migration to our country along the recent years necessitates development of an appropriate health approach concerning asylum seekers.

    Both sensation seeking and affiliation with deviant peer groups are risk factors for delinquency in adolescence. In this study, we use a sample of adolescent twins (n = 549), 13 to 20 years old (M age = 15.8 years), in order to test the interactive effects of peer deviance and sensation seeking on delinquency in a genetically informative design. Consistent with a socialization effect, affiliation with deviant peers was associated with higher delinquency even after controlling for selection effects using a co-twin-control comparison. At the same time, there was evidence for person-environment correlation; adolescents with genetic dispositions toward higher sensation seeking were more likely to report having deviant peer groups. Genetic influences on sensation seeking substantially overlapped with genetic influences on adolescent delinquency. Finally, the environmentally mediated effect of peer deviance on adolescent delinquency was moderated by individual differences in sensation seeking. Adolescents reporting high levels of sensation seeking were more susceptible to deviant peers, a Person × Environment interaction. These results are consistent with both selection and socialization processes in adolescent peer relationships, and they highlight the role of sensation seeking as an intermediary phenotype for genetic risk for delinquency.

    2016-01-01

    Background and aims Online gambling appears to have special features, such as anonymity, speed of play and permanent availability, which may contribute to the facilitation and increase in gambling practice, potentially leading to problem gambling. The aims of this study were to assess sociodemographic characteristics, gambling practice and impulsive sensation seeking among a population of regular poker players with different levels of gambling intensity and to compare online and live players. Methods 245 regular poker players (180 online players and 65 live players) completed online self-report scales assessing sociodemographic data, pathological gambling (SOGS), gambling practice (poker questionnaire) and impulsive sensation seeking (ImpSS). We used SOGS scores to rank players according to the intensity of their gambling practice (non-pathological gamblers, problem gamblers and pathological gamblers). Results All poker players displayed a particular sociodemographic profile: they were more likely to be young men, executives or students, mostly single and working full-time. Online players played significantly more often whereas live players reported significantly longer gambling sessions. Sensation seeking was high across all groups, whereas impulsivity significantly distinguished players according to the intensity of gambling. Discussion Our results show the specific profile of poker players. Both impulsivity and sensation seeking seem to be involved in pathological gambling, but playing different roles. Sensation seeking may determine interest in poker whereas impulsivity may be involved in pathological gambling development and maintenance. Conclusions This study opens up new research perspectives and insights into preventive and treatment actions for pathological poker players. PMID:28092187

    This study aimed to explore the relationship between the four components of sensation seeking (i.e., disinhibition, thrill and adventure seeking, experience seeking, and boredom susceptibility) and three types of smoking behavior (i.e., non-smoking, experimental smoking, and current smoking) among high school students in the Republic of Korea. Multivariate multinomial logistic regression analysis was performed using two models. In Model 1, the four subscales of sensation seeking were used as covariates, and in Model 2, other control factors (i.e., characteristics related to demographics, individuals, family, school, and friends) were added to Model 1 in order to adjust for their effects. In Model 1, the impact of disinhibition on experimental smoking and current smoking was statistically significant. In Model 2, the influence of disinhibition on both of these smoking behaviors remained statistically significant after controlling for all the other covariates. Also, the effect of thrill and adventure seeking on experimental smoking was statistically significant. The two statistically significant subscales of sensation seeking were positively associated with the risk of smoking behaviors. According to extant literature and current research, sensation seeking, particularly disinhibition, is strongly associated with smoking among youth. Therefore, sensation seeking should be measured among adolescents to identify those who are at greater risk of smoking and to develop more effective intervention strategies in order to curb the smoking epidemic among youth.

    A case of sacral herpes zoster infection in a 56-year-old man with the complication of loss of urinary voiding sensation is presented. He had typical herpes zoster eruption on the left S2 dermatome, hypalgesia of the S1-S4 dermatomes, and absence of urinary voiding sensation. There was no other urinary symptom at the first medical examination. Urinary complications associated with herpes zoster are uncommon, but two types, acute cystitis and acute retention, have been recognized. No cases of loss of urinary voiding sensation due to herpes zoster have been reported. In this case, hypalgesia of the sacral dermatomes was mild compared to the marked loss of urethral sensation. This inconsistency is explained by the hypothesis that the number of urethral fibers is very small as compared to that of cutaneous fibers, therefore, urethral sensation would be more severely disturbed than cutaneous sensation.

    Most urethral neuromuscular function data focus on efferent rather than afferent innervation. We aimed to determine if changes exist in urethral afferent nerve function before and after reconstructive pelvic surgery (RPS). Secondarily, we compared afferent urethral innervation in women with and without stress urinary incontinence undergoing RPS. Participants underwent current perception threshold (CPT) and urethral anal reflex (UAR) testing prior to surgery and again post-operatively. Wilcoxon signed ranked test and Spearman's correlations were used and all tests were two-sided. p = 0.05 was considered to indicate statistical significance. Urethral CPT thresholds increased significantly after RPS, consistent with decreased urethral afferent function. Pre-operative urethral CPT thresholds at 5 and 250 Hz were lower in SUI women (10 [IQR 5-29], 40 [32-750]) compared with continent women (63 [14-99], 73 [51-109]; p = 0.45, p = 0.020), signifying increased urethral sensation or easier activation of urethral afferents in SUI women. Reconstructive pelvic surgery is associated with a short-term deleterious impact on urethral afferent function, as demonstrated by the higher levels of stimuli required to activate urethral afferent nerves (decreased urethral sensation) immediately after RPS. Women with SUI required lower levels of stimuli to activate urethral afferent nerves prior to RPS, although UAR latencies were similar regardless of concomitant SUI.

    This study assessed whether subliminal priming of a brand name of a drink can affect people's choices for the primed brand, and whether this effect is moderated by personality traits. Participants with different levels of sensation seeking were presented subliminally with the words Red Bull or Lde Ublr. Results revealed that being exposed to Red Bull lead on average to small increases in participants' preferences for the primed brand. However, this effect was twice as strong for participants high in sensation seeking and did not occur for participants low in sensation seeking. Going beyond previous research showing that situational factors (e.g., thirst, fatigue…) can increase people's sensitivity to subliminal advertisement, our results suggest that some dispositional factors could have the same potentiating effect. These findings highlight the necessity of taking personality into account in non-conscious persuasion research.

    The consumption of caffeine has become a growing concern, partially because of the withdrawal properties of the drug. The current study examined personality correlates of caffeine consumption and dependence in 60 university students. Self-report and behavioral measures of sensation seeking, impulsivity, and risk taking were administered to 2 groups, identified as caffeine dependent-high consuming or caffeine nondependent-low consuming. Scores on self-report measures of sensation seeking and impulsivity were related to group status, and only sensation seeking evidenced a significant relationship with group status when both variables were considered in a regression analysis. Implications of these findings and future directions are discussed. ((c) 2005 APA, all rights reserved).

    Two hundred and thirty men, being treated for ICD-10 diagnosed dependence on alcohol, opioids or both, were studied 2-4 weeks after the last use of alcohol or opioids. Alienation Scale, Sensation Seeking Scale and Muliphasic Personality Questionnaire (MPQ), and selected sociodemographic and family history data were studied. All three groups showed high alienation (more in opioid cases), high sensation seeking (more in alcohol cases, more for boredom susceptibility), and a disturbed MPQ profile. The dual dependence group was similar to opioid group for age, but closer to alcohol group in terms of personality profile. Only alcohol cases showed a significantly positive correlation between alienation and sensation seeking- in terms of total scale, and boredom susceptibility and disinhibition subscales only. Thus, substance specificity was not reflected prominently in the inter-relationships between alienation, sensation seeking and MPQ scores, and sociodemographic variables. PMID:21407879

    Intake of food or fluid distends the stomach and triggers mechanoreceptors and vagal afferents. Wall stretch and tension produces a feeling of fullness. Duodenal infusion studies assessing gastric sensitivity by barostat have shown that the products of fat digestion have a greater effect on the sensation of fullness and also dyspeptic symptoms than carbohydrates. We tested here the hypothesis that fat and carbohydrate have different effects on gastric sensation under physiological conditions using non-invasive magnetic resonance imaging (MRI) to measure gastric volumes. Thirteen healthy subjects received a rice pudding test meal with added fat or added carbohydrate on two separate occasions and underwent serial postprandial MRI scans for 4.5 h. Fullness was assessed on a 100-mm visual analogue scale. Gastric half emptying time was significantly slower for the high-carbohydrate meal than for the high-fat meal, P=0.0327. Fullness significantly correlated with gastric volumes for both meals; however, the change from baseline in fullness scores was higher for the high-fat meal for any given change in stomach volume (P=0.0147), despite the lower energy content and faster gastric emptying of the high-fat meal. Total gastric volume correlates positively and linearly with postprandial fullness and ingestion of a high-fat meal increases this sensation compared with high-carbohydrate meal. These findings can be of clinical interest in patients presenting with postprandial dyspepsia whereby manipulating gastric sensitivity by dietary intervention may help to control digestive sensations.

    A three-part series presents the development of models for predicting the local thermal sensation (Part I) and local thermal comfort (Part II) of different parts of the human body, and also the whole-body sensation and comfort (Part III) that result from combinations of local sensation and comfort. The models apply to sedentary activities in a range of environments: uniform and non-uniform, stable and transient. They are based on diverse findings from the literature and from body-part-specific human subject tests in a climate chamber. They were validated against a test of automobile passengers. The series is intended to present the models' rationale, structure, and coefficients, so that others can test them and develop them further as additional empirical data becomes available. A) The whole-body (overall) sensation model has two forms, depending on whether all of the body's segments have sensations effectively in the same direction (e.g warm or cool), or whether some segments have sensations opposite to those of the rest of the body. For each, individual body parts have different weights for warm versus cool sensations, and strong local sensations dominate the overall sensation. If all sensations are near neutral, the overall sensation is close to the average of all body sensations. B) The overall comfort model also has two forms. Under stable conditions, people evaluate their overall comfort by a complaint-driven process, meaning that when two body parts are strongly uncomfortable, no matter how comfortable the other body parts might be, the overall comfort will be near the discomfort level of the two most uncomfortable parts. When the environmental conditions are transient, or people have control over their environments, overall comfort is better than that of the two most uncomfortable body parts. This can be accounted for by adding the most comfortable vote to the two most uncomfortable ones. (author)

    Full Text Available Introduction. For some time, the issue of participating in high-risk sports, including skydiving, has been linked to the trait of sensation seeking, but skydivers do not constitute a homogeneous group in terms of this factor. The aim of the study was to determine the role of the need for sensation in performing skydiving and to examine whether the importance of this factor differs depending on gender. Material and methods. The study included a total of 143 skydivers (98 men and 45 women aged from 17 to 49 years with different levels of expertise in skydiving. In total, 73 respondents were categorised as novices, and 70 were considered experts. Novice skydivers were defined as having completed no more than 10 jumps in their lives. Expert skydivers were persons who had made at least 100 jumps in their lives and had a licence to perform skydiving independently, without instructor supervision. The need for stimulation was measured using the Sensation Seeking Scale IV by Zuckerman, in its Polish version by Oleszkiewicz-Zsurzs. Results. Since a high proportion of individuals with a strong need for sensation was found among both men and women, it can be concluded that it is an important factor in primary selection in skydiving (when the sport is undertaken, regardless of gender. Conclusions. The significance of sensation seeking as a factor in secondary selection in skydiving (when the sport is being performed differs depending on the particular dimension of sensation seeking and gender. Susceptibility to boredom is probably a significant factor in secondary selection in women.

  7. Elevated hair cortisol concentrations in recently fled asylum seekers in comparison to permanently settled immigrants and non-immigrants.

    Recently fled asylum seekers generally live in stressful conditions. Their residency status is mostly insecure and, similar to other immigrants, they experience stress due to acculturation. Moreover, they often suffer from traumatization and posttraumatic stress disorder (PTSD). All of these factors can result in chronic maladaptive biological stress responses in terms of hyper- or hypocortisolism and, ultimately, illness. We believe the current study is the first to compare hair cortisol concentration (HCC) of recently fled asylum seekers with PTSD to those without PTSD, and to compare HCC of asylum seekers to HCC of permanently settled immigrants and non-immigrant individuals. HCC of the previous 2 months was compared between 24 asylum seekers without PTSD, 32 asylum seekers with PTSD, 24 permanently settled healthy Turkish immigrants and 28 non-immigrant healthy Germans as the reference group. Statistical comparisons were controlled for age, sex and body mass index. No significant difference in HCC was found between asylum seekers with and without PTSD. However, the asylum seekers showed a 42% higher HCC than the reference group. In contrast, the permanently settled immigrants exhibited a 23% lower HCC than the reference group. We found relative hypercortisolism in recently fled asylum seekers, but no difference between persons with and without PTSD. These findings add to the very few studies investigating HCC in groups with recent traumatization and unsafe living conditions. Contrary to the findings in asylum seekers, permanently settled immigrants showed relative hypocortisolism. Both hyper- and hypocortisolism may set the stage for the development of stress-related illnesses.

  8. Turning Asylum Seekers into ‘Dangerous Criminals’: Experiences of the Criminal Justice System of those Seeking Sanctuary

    Full Text Available Since the events of 9/11 in the US in 2001 and, four years later, the 7/7 London bombings in the UK, warnings of terrorist attacks are high on the public agenda in many western countries. Politicians and tabloid press in the UK have continued to make direct and indirect connections between asylum seekers, terrorism and crime. This has increasingly resulted in harsh policy responses to restrict the movement of ‘third-world’ nationals, criminalisation of immigration and asylum policy, and making the violation of immigration laws punishable through criminal courts. This paper largely highlights the narratives of five asylum seekers who committed ‘crime’ by breaching immigration laws and were consequently treated as ‘dangerous criminals’ by the state authorities. More importantly it shows how these individuals experienced this treatment. The aim of this paper is to give voice to the victims of state abuse, claim space for victim agency, gather victim testimonies, challenge official explanations and in the process confront criminal and racist state practices.

    Optimal reactive power dispatch (ORPD) has a growing impact on secure and economical operation of power systems. This issue is well known as a non-linear, multi-modal and multi-objective optimization problem where global optimization techniques are required in order to avoid local minima. In the last decades, computation intelligence-based techniques such as genetic algorithms (GAs), differential evolution (DE) algorithms and particle swarm optimization (PSO) algorithms, etc., have often been used for this aim. In this work, a seeker optimization algorithm (SOA) based method is proposed for ORPD considering static voltage stability and voltage deviation. The SOA is based on the concept of simulating the act of human searching where search direction is based on the empirical gradient by evaluating the response to the position changes and step length is based on uncertainty reasoning by using a simple Fuzzy rule. The algorithm's performance is studied with comparisons of two versions of GAs, three versions of DE algorithms and four versions of PSO algorithms on the IEEE 57 and 118-bus power systems. The simulation results show that the proposed approach performed better than the other listed algorithms and can be efficiently used for the ORPD problem. (author)

    This paper presents the results of a multimodal study of oral perception conducted with a set of material samples made from metals, polymers and woods, in which both the somatosensory and taste factors were examined. A multidimensional scaling analysis coupled with subjective attribute ratings was performed to assess these factors both qualitatively and quantitatively. The perceptual somatosensory factors of warmth, hardness and roughness dominated over the basic taste factors, and roughness was observed to be a less significant sensation compared to touch-only experiments. The perceptual somatosensory ratings were compared directly with physical property data in order to assess the correlation between the perceived properties and measured physical properties. In each case, a strong correlation was observed, suggesting that physical properties may be useful in industrial design for predicting oral perception.

    Intravital microscopy is a powerful tool in neuroscience but has not been adapted to the taste sensory organ due to anatomical constraint. Here we developed an imaging window to facilitate microscopic access to the murine tongue in vivo. Real-time two-photon microscopy allowed the visualization of three-dimensional microanatomy of the intact tongue mucosa and functional activity of taste cells in response to topically administered tastants in live mice. Video microscopy also showed the calcium activity of taste cells elicited by small-sized tastants in the blood circulation. Molecular kinetic analysis suggested that intravascular taste sensation takes place at the microvilli on the apical side of taste cells after diffusion of the molecules through the pericellular capillaries and tight junctions in the taste bud. Our results demonstrate the capabilities and utilities of the new tool for taste research in vivo.

    Although itch sensation is an important protective mechanism for animals, chronic itch remains a challenging clinical problem. Itch processing has been studied extensively at the spinal level. However, how itch information is transmitted to the brain and what central circuits underlie the itch-induced scratching behavior remain largely unknown. We found that the spinoparabrachial pathway was activated during itch processing and that optogenetic suppression of this pathway impaired itch-induced scratching behaviors. Itch-mediating spinal neurons, which express the gastrin-releasing peptide receptor, are disynaptically connected to the parabrachial nucleus via glutamatergic spinal projection neurons. Blockade of synaptic output of glutamatergic neurons in the parabrachial nucleus suppressed pruritogen-induced scratching behavior. Thus, our studies reveal a central neural circuit that is critical for itch signal processing.

  15. Explaining variability in sodium intake through oral sensory phenotype, salt sensation and liking

    Hayes, John E.; Sullivan, Bridget S.; Duffy, Valerie B.

    2010-01-01

    Our sodium-rich food supply compels investigation of how variation in salt sensation influences liking and intake of high-sodium foods. While supertasters (those with heightened propylthiouracil (PROP) bitterness or taste papillae number) report greater saltiness from concentrated salt solutions, the non-taster/supertaster effect on sodium intake is unclear. We assessed taster effects on salt sensation, liking and intake among 87 healthy adults (45 men). PROP bitterness showed stronger associations with perceived saltiness in foods than did papillae number. Supertasters reported: greater saltiness in chips/pretzels and broth at levels comparable to regular-sodium products; greater sensory and/or liking changes to growing sodium concentration in cheeses (where sodium ions mask bitterness) and broths; and less frequently salting foods. PROP effects were attenuated in women. Compared with men, women reported more saltiness from high-sodium foods and greater liking for broth at salt levels comparable to regular-sodium products. Across men and women, Structural Equation Models showed PROP and papillae number independently explained variability in consuming high-sodium foods by impacting salt sensation and/or liking. PROP supertasters reported greater changes in sensation when more salt was added to broth, which then associated with greater changes in broth liking, and finally with more frequent high-sodium food intake. Greater papillae number was associated with less frequent high-sodium food intake via reduced liking for high-fat/high-sodium foods. In summary, variation in sensations from salt was associated with differences in hedonic responses to high-sodium foods and thus sodium intake. Despite adding less salt, PROP supertasters consumed more sodium through food, as salt was more important to preference, both for its salty taste and masking of bitterness. PMID:20380843

    Our motor actions are sometimes not properly performed despite our having complete understanding of the environmental situation with a suitable action intention. In most cases, insufficient skill for motor control can explain the improper performance. A notable exception is the action of stepping onto a stopped escalator, which causes clumsy movements accompanied by an odd sensation. Previous studies have examined short-term sensorimotor adaptations to treadmills and moving sleds, but the relationship between the odd sensation and behavioral properties in a real stopped-escalator situation has never been examined. Understanding this unique action-perception linkage would help us to assess the brain function connecting automatic motor controls and the conscious awareness of action. Here we directly pose a question: Does the odd sensation emerge because of the unfamiliar motor behavior itself toward the irregular step-height of a stopped escalator or as a consequence of an automatic habitual motor program cued by the escalator itself. We compared the properties of motor behavior toward a stopped escalator (SE) with those toward moving escalator and toward a wooden stairs (WS) that mimicked the stopped escalator, and analyzed the subjective feeling of the odd sensation in the SE and WS conditions. The results show that moving escalator-specific motor actions emerged after participants had stepped onto the stopped escalator despite their full awareness that it was stopped, as if the motor behavior was guided by a "phantom" of a moving escalator. Additionally, statistical analysis reveals that postural forward sway that occurred after the stepping action is directly linked with the odd sensation. The results suggest a dissociation between conscious awareness and subconscious motor control: the former makes us perfectly aware of the current environmental situation, but the latter automatically emerges as a result of highly habituated visual input no matter how unsuitable

    Although previous research has identified red as the color of compliance, the current work proposes that this effect of red may not hold under high sensation-seeking propensity conditions. It is argued that the color red has the capability to induce arousal, which in turn has been shown to enhance a

    Human movement sense relies on both somatosensory feedback and on knowledge of the motor commands used to produce the movement. We have induced a movement illusion using repetitive transcranial magnetic stimulation over primary motor cortex and dorsal premotor cortex in the absence of limb movement...... and its associated somatosensory feedback. Afferent and efferent neural signalling was abolished in the arm with ischemic nerve block, and in the leg with spinal nerve block. Movement sensation was assessed following trains of high-frequency repetitive transcranial magnetic stimulation applied over...... premotor cortex stimulation was less affected by sensory and motor deprivation than was primary motor cortex stimulation. We propose that repetitive transcranial magnetic stimulation over dorsal premotor cortex produces a corollary discharge that is perceived as movement....

  3. A novel behavioral assay for measuring cold sensation in mice.

    Directory of Open Access Journals (Sweden)

    Daniel S Brenner

    Full Text Available Behavioral models of cold responses are important tools for exploring the molecular mechanisms of cold sensation. To complement the currently cold behavioral assays and allow further studies of these mechanisms, we have developed a new technique to measure the cold response threshold, the cold plantar assay. In this assay, animals are acclimated on a glass plate and a cold stimulus is applied to the hindpaw through the glass using a pellet of compressed dry ice. The latency to withdrawal from the cooled glass is used as a measure of the cold response threshold of the rodents, and the dry ice pellet provides a ramping cold stimulus on the glass that allows the correlation of withdrawal latency values to rough estimates of the cold response threshold temperature. The assay is highly sensitive to manipulations including morphine-induced analgesia, Complete Freund's Adjuvant-induced inflammatory allodynia, and Spinal Nerve Ligation-induced neuropathic allodynia.

    We present a system to realize an on-line instruction environment among physically separated participants based on a multi-modal communication strategy. In addition to visual and acoustic information, commonly used communication modalities in network environments, our system provides a haptic channel to intuitively conveying partners' sense of touch. The human touch sensation, however, is very sensitive for delays and jitters in the networked virtual reality (NVR) systems. Therefore, a method to compensate for such negative factors needs to be provided. We show an NVR architecture to implement a basic framework that can be shared by various applications and effectively deals with the problems. We take a hybrid approach to implement both data consistency by client-server and scalability by peer-to-peer models. As an application system built on the proposed architecture, a remote instruction system targeted at teaching handwritten characters and line patterns on a Korea-Japan high-speed research network also is mentioned.

  6. Sensation seeking in opium abusers compared to normal people

    2004-05-01

    Full Text Available Recent research shows that it is possible to identify people at risk of substance abuse using some personality variables. Identification of these people might help social planners to deal with these people specifically in their prevention attempts. The aim of this study was to compare the sensation seeking of opium addicted and non-addicted people using the sensation seeking scale. Such a comparison might help to identify personality variables that are effective in turning toward substance abuse. In order to measure the sensation seeking of subjects “Sensation Seeking Scale” (SSS were used. 31 opium abusers were matched to 31 normal controls according to the following variables: age, education, father and mother education. Results showed that opium abusers obtain higher scores on the total sensation seeking score ,“variety seeking” and “experience seeking” subscales.

    2014-01-01

    After adaptation to a fixed temporal delay between actions and their sensory consequences, stimuli delivered during the delay are perceived to occur prior to actions. Temporal judgments are also influenced by the sensation of agency (experience of causing our own actions and their sensory consequences). Sensory consequences of voluntary actions are perceived to occur earlier in time than those of involuntary actions. However, it is unclear whether temporal order illusions influence the sensation of agency. Thus, we tested how the illusionary reversal of motor actions and sound events affect the sensation of agency. We observed an absence of the sensation of agency in the auditory modality in a condition in which sounds were falsely perceived as preceding motor acts relative to the perceived temporal order in the control condition. This finding suggests a strong association between the sensation of agency and the temporal order perception of actions and their consequences. Copyright © 2013 Elsevier Inc. All rights reserved.

  8. Lack of motor prediction, rather than perceptual conflict, evokes an odd sensation upon stepping onto a stopped escalator

    2014-01-01

    When stepping onto a stopped escalator, we often perceive an “odd sensation” that is never felt when stepping onto stairs. The sight of an escalator provides a strong contextual cue that, in expectation of the backward acceleration when stepping on, triggers an anticipatory forward postural adjustment driven by a habitual and implicit motor process. Here we contrast two theories about why this postural change leads to an odd sensation. The first theory links the odd sensation to a lack of sensorimotor prediction from all low-level implicit motor processes. The second theory links the odd sensation to the high-level conflict between the conscious awareness that the escalator is stopped and the implicit perception that evokes an endogenous motor program specific to a moving escalator. We show very similar postural changes can also arise from reflexive responses to visual stimuli, such as contracting/expanding optic flow fields, and that these reflexive responses produce similar odd sensations to the stopped escalator. We conclude that the high-level conflict is not necessary for such sensations. In contrast, the implicitly driven behavioral change itself essentially leads to the odd sensation in motor perception since the unintentional change may be less attributable to self-generated action because of a lack of motor predictions.

    Introduction Italy is the main recipient of asylum seekers in the European region, and Sicily is their first point of arrival. This geographical position creates a large job for Health Authorities to identify and deal with the health of immigrants. This study evaluates the prevalence of disease among asylum seekers, assessing which are associated factors. Methods A cross-sectional study was conducted to analyse demographic and clinical data in an Acceptance Centres for Asylum Seekers from February 2012 to May 2013. All variables that were found to be significant on unvariable analysis for the most frequent pathologies were included in a multivariable logistic regression model. Results Post-traumatic stress disorders with 17.4% and major depression with 7.3% were the most frequent diseases. The factors associated with post-traumatic stress disorders among asylum seekers were: major depression diagnosis (OR=2.91, p=0.004), Pakistan as a country of origin (OR=3.88, pasylum seekers needs special attention, and interventions should be done to prevent the consolidation of psychiatric morbidity. A short psychological screening after the arrival might prove helpful here. Moreover, carefully designed longitudinal studies should be carried out when political recommendations try to change the organization of psychological and healthcare services. PMID:27647085

    To identify low-risk groups among asylum seekers in the Netherlands that may be excluded from tuberculosis (TB) screening at entry or during follow-up. A retrospective cohort study of medical records of asylum seekers entering the country between January 1994 and March 1997. Medical records were available for 46,424 of the 96,000 asylum seekers (48%) in this period. One hundred and three pulmonary TB cases were diagnosed at entry (prevalence 222/100,000). Risk factors were age >11 years, history of imprisonment and country of origin at war or with TB incidence >100/100,000. During a mean follow-up period of 10 months, 51 pulmonary TB cases were diagnosed (incidence 134/100,000 person-years). Risk factors were age >11 years, old lesions on entry X-ray, and country of origin whose asylum seekers had a prevalence of TB at entry >200/100,000. We conclude that 1) those with abnormal X-ray at entry should receive preventive therapy after exclusion of active TB, or undergo intensive follow-up, 2) periodic screening is not indicated for immigrants from countries whose asylum seekers have a low prevalence of pulmonary TB at entry, and 3) children <12 years can be excluded from screening.

    It has been proposed that high rates of risk-taking in adolescence are partly attributable to patterns of neurobiological development that promote an increase in sensation-seeking tendencies at a time when impulse control is still developing. It is not known, however, whether this pattern is the same for males and females. The present study investigates sex differences in the developmental trajectories of self-reported impulse control and sensation-seeking between the ages of 10 and 25 using longitudinal data from the National Longitudinal Study of Youth 1979 Child and Young Adult Survey (N = 8,270; 49% female; 33% Black, 22% Hispanic, 45% Non-Black, Non-Hispanic). Prior work has found that, consistent with the dual-systems model of adolescent neurobiological development, sensation-seeking rises and falls across this age span, whereas impulse control increases into the 20s. In the present study, we find that this same general pattern holds for both males and females, but with some key differences. As expected, males exhibit higher levels of sensation-seeking and lower levels of impulse control than females. Differences also emerged in the shapes of the developmental trajectories. Females reach peak levels of sensation-seeking earlier than males (consistent with the idea that sensation-seeking is linked to pubertal development) and decline in sensation-seeking more rapidly thereafter. Also, males increase in impulse control more gradually than females. Consequently, sex differences in both impulse control and sensation-seeking increase with age. The findings suggest that the window of heightened vulnerability to risk-taking during adolescence may be greater in magnitude and more protracted for males than for females.

  14. Testing for and the role of anal and rectal sensation.

    1992-03-01

    The rectum is insensitive to stimuli capable of causing pain and other sensations when applied to a somatic cutaneous surface. It is, however, sensitive to distension by an experimental balloon introduced through the anus, though it is not known whether it is the stretching or reflex contraction of the gut wall, or the distortion of the mesentery and adjacent structures which induces the sensation. No specific sensory receptors are seen on careful histological examination of the rectum in humans. However, myelinated and non-myelinated nerve fibres are seen adjacent to the rectal mucosa, but no intraepithelial fibres arise from these. The sensation of rectal distension travels with the parasympathetic system to S2, S3 and S4. The two main methods for quantifying rectal sensation are rectal balloon distension and mucosal electrosensitivity. The balloon is progressively distended until particular sensations are perceived by the patient. The volumes at which these sensations are perceived are recorded. Three sensory thresholds are usually defined: constant sensation of fullness, urge to defecate, and maximum tolerated volume. The modalities of anal sensation can be precisely defined. Touch, pain and temperature sensation exist in normal subjects. There is profuse innervation of the anal canal with a variety of specialized sensory nerve endings: Meissner's corpuscles which record touch sensation, Krause end-bulbs which respond to thermal stimuli, Golgi-Mazzoni bodies and pacinian corpuscles which respond to changes in tension and pressure, and genital corpuscles which respond to friction. In addition, there are large diameter free nerve endings within the epithelium. The nerve pathway for anal canal sensation is via the inferior haemorrhoidal branches of the pudendal nerve to the sacral roots of S2, S3 and S4. Anal sensation may be quantitatively measured in response to electrical stimulation. The technique involves the use of a specialized constant current generator

  15. Presentation of Various Tactile Sensations Using Micro-Needle Electrotactile Display.

    Full Text Available Tactile displays provoke tactile sensations by artificially stimulating tactile receptors. While many types of tactile displays have been developed, electrotactile displays that exploit electric stimulation can be designed to be thin, light, flexible and thus, wearable. However, the high voltages required to stimulate tactile receptors and limited varieties of possible sensations pose problems. In our previous work, we developed an electrotactile display using a micro-needle electrode array that can drastically reduce the required voltage by penetrating through the high-impedance stratum corneum painlessly, but displaying various tactile sensations was still a challenge. In this work, we demonstrate presentation of tactile sensation of different roughness to the subjects, which is enabled by the arrangement of the electrodes; the needle electrodes are on the fingertip and the ground electrode is on the fingernail. With this arrangement, the display can stimulate the tactile receptors that are located not only in the shallow regions of the finger but also those in the deep regions. It was experimentally revealed that the required voltage was further reduced compared to previous devices and that the roughness presented by the display was controlled by the pulse frequency and the switching time, or the stimulation flow rate. The proposed electrotactile display is readily applicable as a new wearable haptic device for advanced information communication technology.

    High- and low-avoidance Roman inbred rat strains (RHA-I, RLA-I) were selected for extreme differences in two-way active avoidance. RHA-I rats also express less anxiety than RLA-I rats. This study compared male Roman rats in ethanol preference and sensation/novelty seeking. Rats were first exposed in counterbalanced order to the hole-board test (forced exposure to novelty) and the Y-maze and emergence tests (free choice between novel and familiar locations). Then, rats were tested in 24-h, two-bottle preference tests with water in one bottle and ethanol (2, 4, 6, 8, or 10% in successive days). Compared to RLA-I rats, RHA-I rats showed (1) higher frequency and time in head dipping, (2) higher activity, and (3) lower frequency of rearing and grooming in the hole-board test, and (4) remained in the novel arm longer in the Y-maze test. No strain differences were observed in the emergence test. RHA-I rats exhibited higher preference for and consumed more ethanol than RLA-I rats at all concentrations. However, both strains preferred ethanol over water for 2-4% concentrations, but water over ethanol for 6-10% concentrations. Factorial analysis with all the rats pooled identified a two-factor solution, one grouping preferred ethanol concentrations (2-4%) with head dipping and grooming in the hole board, and another factor grouping the nonpreferred ethanol concentrations (6-10%) with activity in the hole board and novel-arm time in the Y-maze test. These results show that preference for ethanol is associated with different aspects of behavior measured in sensation/novelty-seeking tests. Copyright © 2014 Elsevier Inc. All rights reserved.

    Based on the Dual Systems Model (Somerville et al., 2010; Steinberg, 2010a) and the biosocial-affect model (Romer and Hennessy, 2007) of adolescent sensation seeking and problem behaviors, the present study examined how (affective associations with online games as a mediator) and when (impulsivity as a moderator) did sensation seeking influence online gaming addiction in adolescence. A total of 375 Chinese male adolescents (mean age = 16.02 years, SD = 0.85) from southern China completed anonymous questionnaires regarding sensation seeking, positive affective associations with online games, impulsivity, and online gaming addiction. Our findings revealed that sensation seeking, positive affective associations with online games and impulsivity were each significantly and positively associated with online gaming addiction in adolescents. Positive affective associations mediated the relationship between sensation seeking and online gaming addiction. Further, impulsivity moderated the relationship between positive affective associations and online gaming addiction, such that the association between positive affective association and online gaming addiction was stronger for high than for low impulsivity adolescents. These findings underscore the importance of integrating the biosocial-affect model and the Dual Systems Model to understand how and when sensation seeking impacts adolescent online gaming addiction.

    Substance use has been identified as a major problem on college campuses across the country, with excessive use often leading to unintended and unwanted negative health outcomes. Sensation seeking has been shown to be a consistent predictor of engagement in various health risk behaviors, including substance use. Religiosity has been shown to negatively predict substance use. However, there is mixed evidence on the relations among these risk and protective factors. This may be due to the operational definitions of religiosity in previous research. The current study investigated religiosity as a moderator of the relation between sensation seeking and substance use using robust measures of religiosity. The primary hypotheses were (a) sensation seeking would be positively associated with higher levels of heavy episodic drinking and marijuana use; (b) religiosity would be negatively associated with higher levels of substance use; and (c) religiosity would moderate the relation between sensation seeking and substance use such that, when religiosity was high, there would be no association between sensation seeking and substance use, but at low and moderate levels of religiosity, there would be a positive association between them. Religiosity was a significant moderator of the relation between risk seeking and marijuana use (p sensation seeking and heavy episodic drinking. Religiosity appears to have a stronger buffering effect for illegal drug use compared with alcohol use, perhaps in part because of the relative acceptance of alcohol consumption across major U.S. religious orientations.

    Full Text Available The number of refugees and asylum seekers in Serbia is significantly increasing. Many have experienced traumatic events and suffer from posttraumatic stress disorder and depression. In order to provide them with adequate assistance, caregivers need adjusted assessment tools. The main goal of this research was the adaptation of the Harvard Trauma Questionnaire for working with refugees and asylum seekers in Serbia. A total of 16 focus groups were interviewed in two phases in order to create an adequate list of traumatic events for this population. The adapted list was subsequently administered to 226 persons seeking asylum in Serbia, along with the remaining parts of HTQ, HSCL-25 and BDI-II. Results show that the adapted list of traumatic events, as well as a shorter version, has good validity and other metric properties. The adaptation of the first assessment tool for working with refugees and asylum seekers in Serbia has significant practical implications.

    Prior to legalization of abortion, induced abortions were performed in an illegal manner and that resulted in many complications hence abortion was legalized in India in 1971 and the number of induced abortions has been gradually increasing since then. One way of preventing abortions is to provide family planning services to these abortion seekers so that same is not repeated. The study was performed to find out the acceptance of contraception after abortion. A prospective study was performed over a period of five years from 2010 to 2014. The study group included all the cases reporting for abortion. A proforma was filled in detail to find out the type of contraception being used before pregnancy and acceptance of contraception after abortion. The existing facilities were also evaluated. 1228 abortions were performed over a period of five years. 94.5% of abortions were during the first trimester. 39.9% had not used any contraceptive before, contraceptives used were natural and barrier which had high failure. The main indication for seeking abortion was failure of contraception and completion of family. 39.6% of patients accepted sterilization as a method of contraception. The existing post abortion family planning services are inadequate. Post abortion period is one which is important to prevent subsequent abortions and family planning services after abortion need to be strengthened.

    There is a lack of knowledge about psychosocial resources that may sustain post-resettlement psychological adjustment among unaccompanied minor asylum-seekers. The aim of this study is to investigate the impact of social support from family abroad and friends on acculturation, discrimination, and mental health among these vulnerable children and youth. Questionnaire data were collected from a population-based multi-ethnic sample involving 895 unaccompanied minors resettled in municipalities in all regions of the country. They met in groups in their local communities. The informants were on average 18.6 years, and had an average length of stay in Norway of 3.5 years. The findings showed that the participants suffered from high levels of ongoing war related intrusive symptoms and depression. Still, at the same time they engaged in adaptation processes that are normative to youth with immigrant backgrounds, in terms of constructing supportive networks and developing culture competence. In accordance with the main effect hypothesis, social support had direct effects on depression and indirect effects by increasing culture competence that may aid the young refugees in dealing with discrimination. However, there were no effects of social support on symptoms of PTSD. The findings give direction to areas of interventions, beyond dealing with the sequel of the traumas the unaccompanied minors have been exposed to, not only for clinicians, but also social workers and school personnel. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    In the last few years, Malta has witnessed increasing immigration flows from the Libyan coasts. Public health policies are focused on screening migrants for tuberculosis, whereas no systematic actions against STIs are implemented. The aim of this study is to define the epidemiological profile of asylum seekers in Malta as regards syphilis, hepatitis B, C and latent tuberculosis, thus supporting screening policies. Five hundred migrants living in open centres were screened between December 2010 and June 2011. 83.2% of people was from Somalia, 81.2% males, average age 26.5 years. The tuberculin skin test (TST) was positive in 225 migrants (45%). Latent syphilis was diagnosed in 11 migrants, hepatitis C in 3 and 31 migrants were HBsAg positive. Systematic screening for asymptomatic migrants in Malta is not recommended for hepatitis C and syphilis, given the low prevalence observed. On the contrary, it should be considered for hepatitis B. TST could be indicated as the first step of a two step screening for migrants from countries with high TB incidence. Efficacy and cost-effectiveness could be achieved by further targeting screening to specific subgroups at higher risk of reactivation, such as people living with HIV and subjects affected by chronic diseases.

    Sensations evoked by thermal stimulation (temperature-related sensations) can be divided into two categories, "temperature sensation" and "thermal comfort." Although several studies have investigated regional differences in temperature sensation, less is known about the sensitivity differences in thermal comfort for the various body regions. In the present study, we examined regional differences in temperature-related sensations with special attention to thermal comfort. Healthy male subjects sitting in an environment of mild heat or cold were locally cooled or warmed with water-perfused stimulators. Areas stimulated were the face, chest, abdomen, and thigh. Temperature sensation and thermal comfort of the stimulated areas were reported by the subjects, as was whole body thermal comfort. During mild heat exposure, facial cooling was most comfortable and facial warming was most uncomfortable. On the other hand, during mild cold exposure, neither warming nor cooling of the face had a major effect. The chest and abdomen had characteristics opposite to those of the face. Local warming of the chest and abdomen did produce a strong comfort sensation during whole body cold exposure. The thermal comfort seen in this study suggests that if given the chance, humans would preferentially cool the head in the heat, and they would maintain the warmth of the trunk areas in the cold. The qualitative differences seen in thermal comfort for the various areas cannot be explained solely by the density or properties of the peripheral thermal receptors and thus must reflect processing mechanisms in the central nervous system.

    Globus is a subjective complaint that describes a sensation of a lump or a foreign body in the throat. Despite being a well-known and common clinical condition, the etiological factors have not been definitely elucidated yet. The study was set up to ascertain the relationship between epiglottic cysts and globus sensation. All patients undergoing investigation and treatments for globus sensation were included in the study. Patients with epiglottic cysts but no other possible causes of globus sensation were constituted the series of patients. Patients were asked to assess the levels of complaint before and after the carbon dioxide (CO2) laser excisions of the cysts. Epiglottic cysts were found in 10 (5.4%) of the 182 patients. Three of these 10 patients who had concomitant diseases or conditions that may cause globus sensation and one patient who refused the surgery were excluded from the study. All the remaining six patients reported relief of the globus sensation after the CO2 laser excisions of the cysts. Our results, obtained from this limited series, indicated that epiglottic cysts may be considered as one of the etiological factors of globus sensation.

    In breast reconstruction, sensation in the reconstructed breasts affects the patients' quality of life along with its aesthetic outcome. Fortunately, less invasive procedures such as breast-conservative surgery (BCS) and skin-sparing mastectomy (SSM) have greatly contributed to the improved aesthetic outcome in immediate breast reconstruction. However, there are few reports on the recovery of breast sensation after BCS and SSM. We retrospectively reviewed 104 consecutive patients who underwent immediate breast reconstruction with the latissimus dorsi myocutaneous flap between 2001 and 2006 at our institution. The sensations of pain, temperature, touch, and vibration were examined at the nipple and skin envelope during the follow-up period (range: 12-61 months, mean: 31 months), and a stratified analysis was performed to determine the critical factors affecting the sensation recovery after BCS and SSM. We found that large breast size significantly impaired the recovery of sensation in the nipple and skin envelope after BCS as well as SSM. Older age and high body mass index value were the factors which negatively affected the sensation in the skin envelope after SSM. While all our BCS patients underwent postoperative radiation therapy, it did not negatively affect the recovery of sensation in SSM patients. On the basis of these findings, we could further improve the sensation of the reconstructed breasts after BCS and SSM. Especially after SSM, the use of innervated flaps is recommended in the patients with large breast, increased age, or obesity when the nipple-areola complex is resected.

    Global events like wars and natural disasters have led to the refugee population reaching numbers not seen since the Second World War. Attitudes to asylum have hardened, with the potential to compromise the mental health needs of asylum seekers and refugees. The challenges in providing mental healthcare for asylum seekers and refugees include working with the uncertainties of immigration status and cultural differences. Ways to meet the challenges include cultural competency training, availability of interpreters and cultural brokers as well as appropriately adapting modes of therapy. Service delivery should support adjustment to life in a foreign country. Never has the need been greater for psychiatrists to play a leadership role in the area.

    Wars and violent domestic conflicts have forced millions of people to move outside their homes. Meeting the basic health needs of those people requires an understanding of research activity and research output on this topic. The objective of this study was to shed light on the quantity and impact of medicine - related publications on refugees, asylum seekers and internally displaced people (IDP). Scopus database was used to retrieve required data. Specifically, the number of publications, top productive countries and institutions, highly cited articles, citation analysis, international collaboration, and journals involved in publishing articles on refugees, asylum seekers and IDP were reviewed and analyzed. The time span for the study was set from year 2000 to 2015. Two thousands five hundred and thirty publications were retrieved. The h-index of retrieved articles was 64. A steep rise in number of publications was noticed after 2011. Top productive countries were the United States of America, Australia and the United Kingdom. The American public health institute (Centers for Disease Control and Prevention) and the United Nations refugee agency were among the top active organizations on this topic. Active journals in publishing on health of refugees, asylum seekers and IDP were those on mental health, psychology, public health and general medicine. Publications on Somali, Afghani, Iraqi, and Syrian refugees received a significant share of medicine-related publications. Analysis of publications based on region showed that publications on refugees from Middle East is rising sharply and is approaching those on African refugees. Bibliometric analysis reveals that research publications on refugees have been increasing in a dramatic way and articles are being published in journals with high impact factor and international reputation, not only in general medicine and public health, but also mental health and psychology journals.

    2013-12-01

    Full Text Available Migrants are often referred to as an all encompassing group of people and the “many faces of migration”, the variety of people, legalities and complexities involved, can be overlooked. The same can be said for non-EU migrants in the Irish context. Non-EU migrants (or those that are not Caucasian are generally viewed to be a distinct cohort of comparable migrants. Indeed, these migrants are often portrayed in a broadly negative way by key Irish institutions (such as the parliament or the media, and these representations impact upon how Irish society views non-EU migration and indeed migration in general. While Ireland is by no means the only European country in which this type of practice occurs, this paper aims to draw attention to generalized, inaccurate and misleading representations of non-EU migrants in Ireland, by specifically examining representations of asylum seekers and illegal immigrants. There can be an overlap in how these “types” of migrants are conceptualized and this paper therefore aims to develop an understanding of the implications involved for migrants categorized as an “asylum seeker” or an “illegal immigrant.” Furthermore, these topics are under-researched within the Irish context, yet they receive much political and public attention. At the same time however, this paper aims to challenge the labels assigned to non-EU migrants and the terminology that is used to define their identity so concretely. In the Irish context there is much confusion in relation to the multiple “faces” of non-EU migration, as a range of terminology is used to refer to them. This terminology is often used in an interchangeable manner, in an array of societal contexts. There is a consistent (whether this happens intentionally or unintentionally is debatable misuse of categories and migration terminology in Irish institutional discourses. Quite often those seeking asylum are referred to as illegal immigrants and vice versa

    Full Text Available OBJECTIVE: To evaluate the prognostic value of absent thumb pain sensation in newborns and young infants with birth brachial plexopathy. METHODS: We evaluated 131 patients with birth brachial plexopathy with less than two months of age. Pain sensation was evoked by thumb nail bed compression to evaluate sensory fibers of the upper trunk (C6. The patients were followed-up monthly. Patients with less than antigravity elbow flexion at six months of age were considered to have a poor outcome. RESULTS: Thirty patients had absent thumb pain sensation, from which 26 showed a poor outcome. Sensitivity of the test was 65% and specificity was 96%. CONCLUSION: Evaluation of thumb pain sensation should be included in the clinical assessment of infants with birth brachial plexopathy.

  16. Correlation Factors Describing Primary and Spatial Sensations of Sound Fields

    ANDO, Y.

    2002-11-01

    The theory of subjective preference of the sound field in a concert hall is established based on the model of human auditory-brain system. The model consists of the autocorrelation function (ACF) mechanism and the interaural crosscorrelation function (IACF) mechanism for signals arriving at two ear entrances, and the specialization of human cerebral hemispheres. This theory can be developed to describe primary sensations such as pitch or missing fundamental, loudness, timbre and, in addition, duration sensation which is introduced here as a fourth. These four primary sensations may be formulated by the temporal factors extracted from the ACF associated with the left hemisphere and, spatial sensations such as localization in the horizontal plane, apparent source width and subjective diffuseness are described by the spatial factors extracted from the IACF associated with the right hemisphere. Any important subjective responses of sound fields may be described by both temporal and spatial factors.

    2014-01-01

    There is limited literature on the relationship between sensation seeking and adolescent risk behaviors, particularly among African Americans. We tested the association between psychometrically-derived subscales of the Zuckerman Sensation Seeking Scale and the intercepts and slopes of individual growth curves of conduct problems, sexual risk taking, and substance use from ages 13-18 years by sex. Boys and girls had different associations between sensation seeking and baseline levels and growth of risk behaviors. The Pleasure Seeking scale was associated with baseline levels of conduct problems in boys and girls, baseline substance use in boys, and growth in sexual risk taking and substance use by girls. Girls had the same pattern of associations with the Danger/Novelty scale as the Pleasure Seeking scale. Knowledge about the relationships between adolescent risk taking and sensation seeking can help in the targeted design of prevention and intervention programs for the understudied population of very low-income, African American adolescents.

    Studies show some return of breast sensation after breast reconstruction; however, recovery is variable and unpredictable. Efforts are being made to restore innervation by reattaching nerves (neurotization). We sought to systematically review the literature addressing breast sensation after reconstruction. The following databases were searched: EMBASE, Cochrane, and PubMed. Additionally, the PLASTIC AND RECONSTRUCTIVE SURGERY journal was hand searched from 1960 to 2009. Inclusion criteria included breast reconstruction for cancer, return of sensation with objective results, and patients aged 18 to 90 years. Studies with purely cosmetic procedures, case reports, studies with less than 10 patients, and studies involving male patients were excluded. The initial search yielded 109 studies, which was refined to 20 studies with a total pool of 638 patients. Innervated flaps have a greater magnitude of recovery, which occurs at an earlier stage compared with the noninnervated flaps. Overall, sensation to deep inferior epigastric artery perforator flaps may recover better sensation than transverse rectus abdominis myocutaneous flaps, followed by latissimus dorsi flaps, and finally implants. Women's needs and expectations for sensation have led plastic surgeons to investigate ways to facilitate its return. Studies, however, depict conflicting data. Larger series are needed to define the role of neurotization as a modality for improving sensory restoration. Thieme Medical Publishers.

    Thermal comfort is an essential environmental factor related to quality of life and work effectiveness. We assessed the feasibility of wrist skin temperature monitoring for estimating subjective thermal sensation. We invented a wrist band that simultaneously monitors skin temperatures from the wrist (i.e., the radial artery and ulnar artery regions, and upper wrist) and the fingertip. Skin temperatures from eight healthy subjects were acquired while thermal sensation varied. To develop a thermal sensation estimation model, the mean skin temperature, temperature gradient, time differential of the temperatures, and average power of frequency band were calculated. A thermal sensation estimation model using temperatures of the fingertip and wrist showed the highest accuracy (mean root mean square error [RMSE]: 1.26 ± 0.31). An estimation model based on the three wrist skin temperatures showed a slightly better result to the model that used a single fingertip skin temperature (mean RMSE: 1.39 ± 0.18). When a personalized thermal sensation estimation model based on three wrist skin temperatures was used, the mean RMSE was 1.06 ± 0.29, and the correlation coefficient was 0.89. Thermal sensation estimation technology based on wrist skin temperatures, and combined with wearable devices may facilitate intelligent control of one’s thermal environment. PMID:27023538

    2013-01-01

    Men score higher than women on measures of sensation-seeking, defined as a willingness to engage in novel or intense activities. This sex difference has been explained in terms of evolved psychological mechanisms or culturally transmitted social norms. We investigated whether sex differences in sensation-seeking have changed over recent years by conducting a meta-analysis of studies using Zuckerman's Sensation Seeking Scale, version V (SSS-V). We found that sex differences in total SSS-V scores have remained stable across years, as have sex differences in Disinhibition and Boredom Susceptibility. In contrast, the sex difference in Thrill and Adventure Seeking has declined, possibly due to changes in social norms or out-dated questions on this sub-scale. Our results support the view that men and women differ in their propensity to report sensation-seeking characteristics, while behavioural manifestations of sensation-seeking vary over time. Sex differences in sensation-seeking could reflect genetically influenced predispositions interacting with socially transmitted information.

    Staehr, Mia Antoni; Munk-Andersen, Ebbe

    2006-04-24

    Our aim was to examine suicidal behaviours among asylum seekers in Denmark. A retrospective quantitative analysis of data from reports to the Danish Red Cross Asylum Department on suicidal behaviours among persons over 15 years of age in the period 2001-2003 and from 54 medical records of suicidal asylum seekers in Denmark in 2001 was carried out. The number of suicide attempts by asylum seekers in 2001 was 3.4 times higher than by Danish residents. Furthermore, the rate of suicide attempts by asylum seekers grew in the following two years. Suicidal behaviours are most frequent among asylum seekers between 30 and 39 years of age. There are national differences. The preferred method of suicide attempt is intake of medicine. Stress-related diagnoses constitute three fourths of all diagnoses. One analysis suggests that the long waiting time (average 20.8 months) faced by asylum seekers combined with rejection of asylum cases may trigger a rapid suicidal reaction. Other factors may also be active, as 44% of suicide attempts occur within six months after arrival in the country. The results are discussed in relation to other research on the vulnerability of refugees, immigrants and asylum seekers and also in relation to length of waiting time, growing mental morbidity and the increasing number of rejections of asylum applications during recent years, a period characterized by a reduction of staff at the asylum centers. It is recommended that prevention of suicidal behaviour shall be given higher legal and administrative priority.

  13. Elevated hair cortisol concentrations in recently fled asylum seekers in comparison to permanently settled immigrants and non-immigrants

    Recently fled asylum seekers generally live in stressful conditions. Their residency status is mostly insecure and, similar to other immigrants, they experience stress due to acculturation. Moreover, they often suffer from traumatization and posttraumatic stress disorder (PTSD). All of these factors can result in chronic maladaptive biological stress responses in terms of hyper- or hypocortisolism and, ultimately, illness. We believe the current study is the first to compare hair cortisol concentration (HCC) of recently fled asylum seekers with PTSD to those without PTSD, and to compare HCC of asylum seekers to HCC of permanently settled immigrants and non-immigrant individuals. HCC of the previous 2 months was compared between 24 asylum seekers without PTSD, 32 asylum seekers with PTSD, 24 permanently settled healthy Turkish immigrants and 28 non-immigrant healthy Germans as the reference group. Statistical comparisons were controlled for age, sex and body mass index. No significant difference in HCC was found between asylum seekers with and without PTSD. However, the asylum seekers showed a 42% higher HCC than the reference group. In contrast, the permanently settled immigrants exhibited a 23% lower HCC than the reference group. We found relative hypercortisolism in recently fled asylum seekers, but no difference between persons with and without PTSD. These findings add to the very few studies investigating HCC in groups with recent traumatization and unsafe living conditions. Contrary to the findings in asylum seekers, permanently settled immigrants showed relative hypocortisolism. Both hyper- and hypocortisolism may set the stage for the development of stress-related illnesses. PMID:28267148

  14. Australian asylum policies: have they violated the right to health of asylum seekers?

    2009-02-01

    Notwithstanding recent migration policy amendments, there is concern that Australian asylum policies have disproportionately burdened the health and wellbeing of onshore asylum seekers. There may be a case to be made that Australian governments have been in violation of the right to health of this population. The objective of this paper is to critically examine these issues and assess the implications for public health practice. The author undertook a review of the recent empirical literature on the health effects of post-migration stressors arising from Australian policies of immigration detention, temporary protection and the restriction of Medicare to some asylum seekers. This evidence was examined within the context of Australia's international law obligations. Findings reveal that Australian asylum policies of detention, temporary protection and the exclusion of some asylum seekers from Medicare rights have been associated with adverse mental health outcomes for this population. This is attributable to the impact of these policies on accessing health care and the underlying determinants of health for asylum seekers. It is arguable that Australian Governments have been discriminating against asylum seekers by withholding access on the grounds of their migration status, to health care and to the core determinants of health in this context. In so doing, Australia may have been in violation of its obligation to respect the right to health of this population. While the 'right to health' framework has much to offer public health, it is an undervalued and poorly understood discipline. The author argues for more education, research and advocacy around the intersection between heath and human rights.

  15. Beyond the genetic basis of sensation seeking: The influence of birth order, family size and parenting styles

    Directory of Open Access Journals (Sweden)

    Feij, Jan A,

    2010-12-01

    Full Text Available Genetic analyses of sensation seeking have shown fairly high heritabilities for measures of this trait. However, 40 to 60% of the variance remains unexplained by genetic factors. This longitudinal study examines the influence of characteristics of the family environment -- birth order, family size, socio-economic status and parenting styles -- on two dimensions of sensation seeking: disinhibition and boredom susceptibility. Previous research has shown that these dimensions load on the same factor, are related to biologically based impulsive disorders, and have a common genetic basis. Questionnaire and biographical data obtained from 532 female and 479 male young adults (age between 18 and 30 years were analyzed using structural modeling. The results show that participants who experienced little parental care and much control were more likely to have high scores on disinhibition and boredom susceptibility. It appears that these family factors may partly explain the previously reported effects of birth order and family size on sensation seeking.

A cognitive model of aetiology of panic disorder assumes that people who experience frequent panic attacks have tendencies to catastrophically interpret normal and benign somatic sensations - as signs of serious illness. This arise the question: is this cognition specific for patients with panic disorder and in what intensity it is present in patients with serious somatic illness and in healthy subjects. Objective. The aim of the study was to ascertain the differences in the frequency and intensity of 'catastrophic' cognitions related to body sensations, and to ascertain the differences in the frequency and intensity of anxiety caused by different body sensations all related to three groups of subjects: a sample of patients with panic disorder, a sample of patients with history of myocardial infarction and a sample of healthy control subjects from general population. Methods. Three samples are observed in the study: A 53 patients with the diagnosis of panic disorder; B 25 patients with history of myocardial infarction; and C 47 healthy controls from general population. The catastrophic cognitions were assessed by the Agoraphobic Cognitions Questionnaire (ACQ and the Body Sensations Questionnaire (BSQ. These questionnaires assess the catastrophic thoughts associated with panic and agoraphobia (ACQ and the fear of body sensations (BSQ. All study subjects answered questionnaires items, and the scores of the answers were compared among the groups. Results. The results of the study suggest that: 1 There is no statistical difference in the tendency to catastrophically interpret body sensations and therefore to induce anxiety in the samples of healthy general population and patients with history of myocardial infarction; 2 The patients with panic disorder have a statistically significantly more intensive tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in comparison to the

    Media-based rehabilitation provides a powerful opportunity to examine vocational behaviors in the disability sector. However, this research is preliminary at best. This paper reports pilot data. Eighteen adults with multiple sclerosis (MS) accessed an email-delivered, resource-based package, Work and MS. Pre- and post-access vocational self-efficacy and identity (Job-Procurement Self Efficacy Scale, My Vocational Situation Scale- primary outcomes), life orientation and depressed mood (Life Orientation Test - revised and Patient Health Questionnaire-9 - secondary outcomes) were assessed. Pre- and post-change scores were examined with Wilcoxon signed ranks tests and Hedges g effect sizes with associated 95% confidence intervals. Reliable change analyses were additionally calculated to determine the clinical significance of individual change scores. Significant and positive effects were reported for vocational self-efficacy, identity, and optimism. Reliable change scores in one or more of these key outcomes were reported by 30% of the sample. Satisfaction with the content and delivery of the email-based intervention was also noted. Preliminary evidence suggests that Work and MS can help to promote vocational goals, interests and strengths among job seekers with a disability by providing a set of tools, information and linkages relating to vocational pursuits and career development. Replication with a randomized control design is indicated. Implications for Rehabilitation Research indicates a high unemployment rate among working-age adults with MS. A combination of disease-specific, psychological, programmatic and societal variables contribute to employment instability in this group. This pilot study demonstrates that an e-mail-based resource package, Work and MS, provides an innovative and feasible option for promoting consumer engagement with vocational services and, potentially, improving vocational outcomes. Work and MS has potential applicability to other

    There have been several studies which have tried to clarify the neural mechanisms of fatigue sensation; however fatigue sensation has multiple aspects. We hypothesized that past experience related to fatigue sensation is an important factor which contributes to future formation of fatigue sensation through the transfer to memories that are located within specific brain structures. Therefore, we aimed to investigate the neural mechanisms of fatigue sensation related to memory. In the present s...

    Sensation Seeking has repeatedly been related to substance use. Also, its role as a correlate of Gambling Disorder has been discussed although research has led to heterogeneous results. Likewise, first studies on Internet Addiction have indicated increased Sensation Seeking, to some extent contradicting clinical impression of patients suffering from internet addiction. We assessed Sensation Seeking in a clinical sample of n=251 patients with Gambling Disorder, n=243 patients with internet addiction, n=103 clients with excessive but not addictive internet use, and n=142 healthy controls. The clinical groups were further sub-divided according to the preferred type of addictive behavior (slot-machine gambling vs. high arousal gambling activities and internet gaming disorder vs. other internet-related addictive behaviors). Decreased scores in some subscales of Sensation Seeking were found among male patients compared to healthy controls with no differences between patients with Gambling Disorder and Internet Addiction. The type of preferred gambling or online activity was not related to differences in Sensation Seeking. Previous findings indicating only small associations between Sensation Seeking and Gambling Disorder were confirmed. Regarding Internet Addiction our results contradict findings from non-clinical samples. Sensation Seeking might be relevant in initiating contact to the health care system.

    Full Text Available Abstract Background Deqi is defined in relation to acupuncture needling as a sensory perception of varying character. In a recently published sham laser validation study, we found that subjects in the verum and the sham laser group experienced deqi sensations. Therefore, we aim to further analyze whether the perceptions reported in the two study arms were distinguishable and whether expectancy effects exhibited considerable impact on our results. Methods A detailed re-analysis focusing on deqi sensations was performed from data collected in a previously published placebo-controlled, double-blind, clinical cross-over trial for a sham laser evaluation. Thirty-four healthy volunteers (28 ± 10.7 years; 16 women, 18 men received two laser acupuncture treatments at three acupuncture points LI4 (hégu, LU7 (liéque, and LR3 (táichong; once by verum laser and once using a sham device containing an inactive laser in randomized order. Outcome measures were frequency, intensity (evaluated by visual analogue scale; VAS, and quality of the subjects' sensations perceived during treatments (assessed with the "acupuncture sensation scale". Results Both, verum and the sham laser acupuncture result in similar deqi sensations with regard to frequency (p-value = 0.67, intensity (p-value = 0.71 and quality (p-values between 0.15 - 0.98. In both groups the most frequently used adjectives to describe these perceptions were "spreading", "radiating", "tingling", "tugging", "pulsing", "warm", "dull", and "electric". Sensations reported were consistent with the perception of deqi as previously defined in literature. Subjects' conviction regarding the effectiveness of laser acupuncture or the history of having received acupuncture treatments before did not correlate with the frequency or intensity of sensations reported. Conclusions Since deqi sensations, described as sensory perceptions, were elicited without any cutaneous sensory input, we assume that they are a

    Full Text Available The aim of the present paper was to clarify how the distinction of self- (sense of agency, SOA and other-produced behavior can be synthesized and recognized in multisensory integration as our cognitive processes. To address this issue, we used tickling paradigm that it is hard for us to tickle ourselves. Previous studies show that tickle sensation by their own motion increases if more delay is given between self-motion of tickling and tactile stimulation (Blakemore et al. 1998, 1999. We introduced visual feedbacks to the tickling experiments. In our hypothesis, integration of vision, proprioception, and motor commands forms the SOA and disintegration causes the breakdown the SOA, which causes the feeling of others, producing tickling sensation even by tickling oneself. We used video-see-through HMD to suddenly delay the real-time images of their hand tickling motions. The tickle sensation was measured by subjective response in the following conditions; 1 tickling oneself without any visual modulation, 2 tickled by others, 3 tickling oneself with visual feedback manipulation. The statistical analysis of ranked evaluation of tickle sensations showed that the delay of visual feedback causes the increase of tickle sensation. The SOA was discussed with Blakemore's and our results.

    People performing actions together have a natural tendency to synchronize their behavior. Consistently, people doing a task together build internal representations not only of their actions and goals, but also of the other people performing the task. However, little is known about which are the behavioral mechanisms and the psychological factors affecting the subjective sensation of synchrony, or “connecting” with someone else. In this work, we sought to find which factors induce the subjective sensation of synchrony, combining motion capture data and psychological measures. Our results show that the subjective sensation of synchrony is affected by performance quality together with task category, and time. Psychological factors such as empathy and negative subjective affects also correlate with the subjective sensation of synchrony. However, when people estimate synchrony as seen from a third person perspective, their psychological factors do not affect the accuracy of the estimation. We suggest that to feel this sensation it is necessary to, first, have a good joint performance and, second, to assume the existence of an attention monitoring mechanism that reports that the attention of both participants (self and other) is focused on the task.

    2015-08-01

    Full Text Available There are at least three different viewpoints among all theories of emotions that attempt to explain the role of body sensations in understanding one's own emotions. In order to compare the explanatory resources of these viewpoints we conducted a research in which the subjects (n=59 were shown a series of neutral and emotionally significant slides (taken from the IAPS database. During the slideshow we registered the subjects' pulse and galvanic skin response. The subjects were asked to assess the intensity of their emotional reactions and body sensations in response to the emotionally significant slides, and also filled in a questionnaire on emotional intelligence that enabled us to measure their ability to understand their own emotions as well as those of other people. The outcomes of our research show that sensations accompanying emotional experiences are not the result of interoception as they do not correspond with objective indicators of the changes in physiological arousal, whereas they do correspond in many ways with the subjects' emotional appraisal of the stimuli and selfassessment of sensations. These outcomes also revealed that subjective evaluations of body sensations correlate with emotional valence, while heart rate (the objective indicator of arousal correlates with modality of the emotion

    The objective of the study was to evaluate the association between changes in laryngeal sensation and initiation of swallowing reflex or swallowing function before and after (chemo)radiotherapy. A prospective study was conducted in a tertiary referral university hospital. Thirteen patients who received (chemo)radiotherapy for treatment of laryngeal or hypopharyngeal cancer were included. Laryngeal sensation was evaluated at the tip of the epiglottis before and 1, 3 months, and 1 year after (chemo)radiotherapy. Videofluoroscopy was performed at the same time. Quantitative determinations included changes in laryngeal sensation, computed analysis of pharyngeal delay time, the distance and velocity of hyoid bone movement during the phase of hyoid excursion, and pharyngeal residue rate (the proportion of the bolus that was left as residue in the pharynx at the first swallow). Laryngeal sensation significantly deteriorated 1 month after (chemo)radiotherapy, but there was a tendency to return to pretreatment levels 1 year after treatment. Neither pharyngeal delay time nor displacement of the hyoid bone changed significantly before and after (chemo)radiotherapy. In addition, there was no significant difference in the mean velocity of hyoid bone movement and the amount of stasis in the pharynx at the first swallow before and after (chemo)radiotherapy. After (chemo)radiotherapy, laryngeal sensation deteriorated. But, in this study, videofluoroscopy showed that swallowing reflex and function were maintained.

    This study determined whether expert swimmers, compared with nonexperts, have superior movement perception and physical sensations of propulsion in water. Expert (national level competitors, n = 10) and nonexpert (able to swim 50 m in > 3 styles, n = 10) swimmers estimated distance traveled in water with their eyes closed. Both groups indicated their subjective physical sensations in the water. For each of two trials, two-dimensional coordinates were obtained from video recordings using the two-dimensional direct linear transformation method for calculating changes in speed. The mean absolute error of the difference between the actual and estimated distance traveled in the water was significantly lower for expert swimmers (0.90 ± 0.71 meters) compared with nonexpert swimmers (3.85 ± 0.84 m). Expert swimmers described the sensation of propulsion in water in cutaneous terms as the "sense of flow" and sensation of "skin resistance." Therefore, expert swimmers appear to have a superior sense of distance during their movement in the water compared with that of nonexpert swimmers. In addition, expert swimmers may have a better perception of movement in water. We propose that expert swimmers integrate sensations and proprioceptive senses, enabling them to better perceive and estimate distance moved through water.

    Full Text Available The increasing number of refugees seeking asylum in Europe in recent years poses new challenges for the healthcare systems in the destination countries. The goal of the study was to describe the evolution of medical problems of asylum seekers at a tertiary care centre in Switzerland.At the University Hospital Basel, we compared all asylum seekers during two 1-year time periods in 2004/05 and 2014/15 concerning demographic characteristics and reasons for referrals and hospitalizations.Hundred ninety five of 2'544 and 516 of 6'243 asylum seekers registered at the national asylum reception and procedure centre Basel were referred to the University Hospital Basel in 2004/05 and 2014/15, and originated mainly from Europe (62.3%, mainly Turkey and Africa (49.1%, mainly Eritrea, respectively. Median age was similar in both study periods (26.9 and 26.2 years. Infectious diseases in asylum seekers increased from 22.6% to 36.6% (p<0.001 and were the main reasons for hospitalizations (33.3% of 45 and 55.6% of 81 hospitalized patients, p = 0.017 in 2004/05 compared to 2014/15. The leading infectious diseases in hospitalized patients were tuberculosis (n = 4 and bacterial skin infections (n = 2 in 2004/05; Malaria (n = 9, pneumonia (n = 6, Chickenpox (n = 5, other viral infections (n = 5 and bacterial skin infections (n = 5 in 2014/15. Infectious diseases like malaria, cutaneous diphtheria, louseborne-relapsing fever or scabies were only found in the second study period. Almost one third of the admitted asylum seekers required isolation precautions with median duration of 6-9.5 days in both study periods.The changing demography of asylum seekers arriving in Switzerland in the current refugee crisis has led to a shift in disease patterns with an increase of infectious diseases and the re-emergence of migration-associated neglected infections. Physicians should be aware of these new challenges.

    Full Text Available In a digital world, job seekers prefer to use e-recruitment for a vacancy searching. Thus, the explanation of the determinants of their attitude in using this technology is left unobserved. This article reports the result of a survey study on how users utilize e-recruitment to search for works. Three hundred eighty-five just-graduated undergraduate students answered questions regarding their intention of using the e-recruitment under Theory of Acceptance Model. We propose Perceived Usefulness, Perceived Ease of Use, and Perceived of Enjoyment as the determinants of the job seekers intention. Results showed that those three variables influence the decision making of job seekers. We found also Perceived Usefulness is the mediating effect for jobs seekers in easy-to-use and enjoy feeling. This article provides evidence that e-recruitment has to be friendly user and fun to use to attract job seekers intention.   Keywords: E-recruitment, perceived usefulness, perceived ease of use, perceived of enjoyment, job seekers.

    The length of stay in asylum centres is generally mentioned as a possible health risk to asylum seekers. Medical staff working with asylum seekers has claimed that long lengths of stay in asylum centres might cause or aggravate mental disorders. We used records from a large, multiethnic group of asylum seekers to study if the incidence of mental disorders increased with length of stay. The study population was asylum seekers in Danish asylum centres run by the Danish Red Cross. General medical care was provided by Red Cross staff who could refer selected cases to medical specialists. If an asylum seeker needed more than three specialist consultations for mental illness or five consultations for physical illness the referrals had to be approved by The Danish Immigration Service. Between July 2001 - December 2002 the Red Cross prospectively registered health related data on all new applications (n = 4516) to the Immigration Service regarding referrals to medical specialists. We used these records to analyse the association between length of stay in the asylum centres and overall rate of referral for mental disorders. Data was analysed using weighted linear regression. We found that referrals for mental disorders increased with length of stay in asylum centres in a large, multiethnic population of asylum seekers. The association was found in all the categories of psychiatric illness studied and for a majority of the nationality groups studied. Length of stay in asylum centres was associated with an increase in referrals for mental disorders in a large, multiethnic group of asylum seekers. The present study supports the view that prolonged length of stay in an asylum centre is a risk factor for mental health. The risk of psychiatric illness among asylum seekers should be addressed by political and humanitarian means, giving prevention of illness the highest priority.

    Refugees in western countries often face long juridical procedures before their requests for a resident permit is granted. The, still scanty, literature shows high prevalence rates of psychopathology among asylum seekers, but there has been little interest for other impaired dimensions of health. The present study is part of a community-based mental health survey among Iraqi asylum seekers in the Netherlands, conducted between November 2000 and September 2001, on the risks of a long asylum procedure. The objectives of this study were to explore quality of life (QoL), disability and physical health and their relationships with psychopathology and pre- and post-migration variables. Two groups of pre-stratified (length of asylum procedure), randomly selected Iraqi asylum seekers (N = 143 and N = 151), were interviewed with fully structured, culturally validated questionnaires. Quality of life was examined with QoLWHO-Bref, functional disability with the Brief Disability Questionnaire and physical health with a newly developed questionnaire. Psychiatric (DSM IV) disorders were measured with the WHO Composite International Diagnostic Interview 2.1. Multivariate logistic regression analyses were used to estimate the relationships between the outcome measures and socio-demographics, adverse life events in Iraq, post-migration living problems (PMLP) and psychopathology. Respondents with a long asylum procedure reported significantly lower QoL, higher functional disability and more physical complaints. Multivariate regression shows that length of stay is the strongest predictor for a low overall QoL. In addition, lower QoL was predicted by psychopathology, higher age, adverse life events in the Netherlands and the PMLP-clusters: family issues, socio-economic living conditions and socio-religious aspects. Disability was predicted by psychopathology, higher age and the PMLP clusters: family issues and socio-religious aspects. Physical complaints were predicted by length of

  14. The relationship between bioclimatic thermal stress and subjective thermal sensation in pedestrian spaces

    2014-12-01

    Outdoor thermal comfort has important implications for urban planning and energy consumption in the built environment. To better understand the relation of subjective thermal experience to bioclimatic thermal stress in such contexts, this study compares micrometeorological and perceptual data from urban spaces in the hot-arid Negev region of Israel. Pedestrians reported on their thermal sensation in these spaces, whereas radiation and convection-related data were used to compute the Index of Thermal Stress (ITS) and physiologically equivalent temperature (PET). The former is a straightforward characterization of energy exchanges between the human body and its surroundings, without any conversion to an "equivalent temperature." Although the relation of ITS to subjective thermal sensation has been analyzed in the past under controlled indoor conditions, this paper offers the first analysis of this relation in an outdoor setting. ITS alone can account for nearly 60 % of the variance in pedestrians' thermal sensation under outdoor conditions, somewhat more than PET. A series of regressions with individual contextual variables and ITS identified those factors which accounted for additional variance in thermal sensation, whereas multivariate analyses indicated the considerable predictive power ( R-square = 0.74) of models including multiple contextual variables in addition to ITS. Our findings indicate that pedestrians experiencing variable outdoor conditions have a greater tolerance for incremental changes in thermal stress than has been shown previously under controlled indoor conditions, with a tapering of responses at high values of ITS. However, the thresholds of ITS corresponding to thermal "neutrality" and thermal "acceptability" are quite consistent regardless of context.

  16. Consequences of tuberculosis among asylum seekers for health care workers in Germany.

    2016-01-01

    Immigrants have been contributing to the incidence of tuberculosis (TB) in Germany for many years. The current wave of migration of asylum seekers to Germany may increase that figure. Healthcare workers (HCW) who look after refugees not only in hospitals and medical practices but also in aid projects may be exposed to cases of TB. The incremental TB cases arising from imported TB as well as from TB cases that developed later in refugees were calculated in a Markov model over a period of 5 years. Infectious and non-infectious susceptible TB and multidrug-resistant TB (MDR-TB) cases were determined separately. In addition, the total amount of latent TB in contact persons and the risk of infection by HCW were estimated. Due to uncertainty of future refugee flows to Europe, different scenarios were considered in univariate and multivariate sensitivity analysis. Assuming a decrease in immigration by half each year to the bottom line of 2014, and in light of the current number of 800,000 asylum seekers, we calculated an additional 10,090 TB cases by the end of the fifth year (5976 cases of infectious pulmonary TB and 143 cases of pulmonary MDR-TB). In case of an unchanging influx of asylum seekers over the 5-year period, 19,031 TB cases would arise, 377 of which infectious MDR-TB. Eighty -seven ensuing TB cases would develop in HCW in the same period, 3 of which MDR-TB cases. Although the total number of TB cases in HCW expected to ensue from the current influx of asylum seekers is rather small, the 3 MDR-TB cases we calculated have to be taken seriously. We consider it essential to increase awareness of protective measures such as respiratory masks and, in the event of documented exposure, of supply-oriented occupational health screening.

  17. The Constitutional Court Adjudication and Its Implications for the Justice Seekers

    OpenAIRE

    2008-01-01

    The Constitutional Court adjudication, as the nature of a court decision, implies the rights that the justice seekers will appreciate. It is unfortunate, however, that the appeal procedures for those who dissatisfied with such adjudication has yet to be issued, and this may produce the disadvantages for the purpose of affording justice. For such reason, the amendment on Procedures of the Constitutional Court, particularly in the appeal procedures, is very much needed.

    In December 2015, an asylum seeker originating from Afghanistan was diagnosed with respiratory diphtheria in Finland. He arrived in Finland from Sweden where he had already been clinically suspected and tested for diphtheria. Corynebacterium diphtheriae was confirmed in Sweden and shown to be genotypically and phenotypically toxigenic. The event highlights the importance of early case detection, rapid communication within the country and internationally as well as preparedness plans of diphtheria antitoxin availability.

  20. Ethics and exclusion: representations of sovereignty in Australia’s approach to asylum-seekers

    OpenAIRE

    Gelber, Katherine; McDonald, Matt

    2006-01-01

    From 2001, the Australian government has justified a hard-line approach to asylum-seekers on the basis of the need to preserve its sovereignty. This article critically evaluates this justification, arguing that the conception of sovereignty as the ‘right to exclude’ involves a denial of responsibility to the most vulnerable in global politics. We particularly focus here on the ways in which the Australian government has attempted to create support for this conception of sovereignty and ethica...

    Development and testing of two mechanisms using a shape memory alloy metal (NITINOL) as the power source are described. The two mechanisms developed are a passive Sun Seeker/Tracker and a generic type power module. These mechanisms use NITINOL wire initially strained in pure torsion which provides the greatest mechanical work capacity upon recovery, as compared to other deformation modes (i.e., tension, helical springs, and bending).

    Vibrotactile sensation mediated is highly dependent on surface mechanical and frictional properties. Dehydration of skin could change these properties. To investigate the relationship between friction and vibrotactile sensation of normal and dehydrated skin. Vibrations were firstly measured during surface exploration using a biomimetic sensor. Piglet skin was used as human skin model to study frictional properties for both normal and dehydrated skin using an atomic force microscope on nanoscale and a pin-on-disk tribometer on macroscale. Effect of vibrational frequency on friction and vibrotactile perception was also observed on nano and macro scale for normal and dehydrated skin. The result indicated that dehydrated skin was less sensitive than normal skin. The coefficient of friction of dehydrated skin is smaller than that of normal skin on both nano and macro scale. The coefficient of friction increases as increasing scanning frequencies. There is a positive correlation between coefficient of friction and vibrotactile sensation on nanoscale and macroscale. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Cutaneous sensations at electrode sites during the administration of direct current brain stimulation may inadvertently influence participants' subjective experience and task performance. The present study evaluated the utility of a methodological variation that substitutes sham administration with very low intensity (0.5 mA) current delivery. We used a 4 × 1 high-definition ring electrode transcranial direct current (HD-tDCS) system to target the left dorsolateral prefrontal cortex (Brodmann's Area 9). Four stimulation conditions were compared in a repeated-measures design: sham 2.0 mA and 0.5 mA intensity, versus active 2.0 mA and 0.5 mA intensity. During stimulation participants performed a cognitive interference task that activates the cingulo-frontal-parietal network, and periodically provided perceived sensation ratings. We demonstrate that a relatively low intensity control condition attenuates otherwise large differences in perceived sensation between active and sham conditions. Critically, behavioral task differences maintained between the two active conditions. A low intensity control stimulation condition may prove a viable methodological alternative to conventional sham techniques used in repeated-measures designs, though important limitations are discussed.

    Internationally, a high number of refugees are in need of help as a consequence of post-traumatic stress or acculturation problems. The present study investigated the gender-specific requirements for such interventions taking clinical symptoms as well as coping strategies into account. Five psychometric instruments assessing anxiety, depression, posttraumatic stress, somatic symptoms, and social adaptation were administered and semi-structured interviews with n = 150 asylum seekers and refugees from Chechnya, Afghanistan, and West Africa were conducted. On the level of total test scores, women reported significantly more somatic symptoms than men but there were no further gender differences. On the item level of the questionnaires as well as with respect to the categories obtained from the interview data, marked gender differences were found. Women, as compared to men, reported more somatic symptoms, emotional outbursts, and loss of sexual interest, while men reported detachment. For women, typical coping strategies were concentrating on their children and various indoor activities, while men preferred looking for work and socializing. Social psychiatric interventions should take gender-specific symptoms and coping strategies into account. For asylum seekers and refugees, same gender client-therapist dyads and groups are highly recommended.

    Full Text Available The case of refugees and asylum-seekers constitutes one of the most important problems of today’s developed and developing countries. Immigration and sanctuary which arise generally from economic causes have reached a more intensified state due to deficiencies in the process of democratization and establishment of an environment of peace. Although it is difficult to provide an exact number, it is observed that a population of more than 10 million people in the world today continue their lives outside their home countries and seek new environments for survival. It is known that refugee mobility follows a route from the south to northern countries and in the case of Turkey it is realized along the coastal lines and through east/south highways, and occupies a significant area of coverage in the Turkish printed media. This article aims to analyze and evaluate the media language and discourse on the lives of refugees or asylum seekers through the perspective of democratization and human rights. Critical discourse analysis will be used to analyze the main axes of enquiry which include the news released in the Turkish printed media on refugees and asylum seekers, the approach adopted in shaping such news coverage, the messages they convey, and their role in molding public opinion

  10. Helping professionals and Border Force secrecy: effective asylum-seeker healthcare requires independence from callous policies.

    Dudley, Michael

    2016-02-01

    To examine the Australian Border Force Act (BFA) and its context, its implications for asylum-seeker healthcare and professionals, and contemporary and historical parallels. Prolonged immigration detention and policies aiming to deter irregular migration cause maritime asylum-seekers undeniable, well-publicised harms and (notwithstanding claims about preventing drownings) show reckless indifference and calculated cruelty. Service personnel may be harmed. Such policies misuse helping professionals to underwrite state abuses and promote public numbing and indifference, resembling other state abuses in the 'war on terror' and (with qualification) historical counterparts, e.g. Nazi Germany. Human service practitioners and organisations recently denounced the BFA that forbids disclosure about these matters.Continuing asylum-seeker healthcare balances the likelihood of effective care and monitoring with lending credibility to abuses. Boycotting it might sacrifice scrutiny and care, fail to compel professionals and affect temporary overseas workers. Entirely transferring healthcare from immigration to Federal and/or State health departments, with resources augmented to adequate standard, would strengthen clinical independence and quality, minimise healthcare's being securitised and politicised, and uphold ethical codes. Such measures will not resolve detention's problems, but coupled with independent auditing, would expose and moderate detention's worst effects, promoting changes in national conversation and policy-making. © The Royal Australian and New Zealand College of Psychiatrists 2016.

  11. What Factors Are Associated with Autonomous and Controlled Motivation for Hearing Help-Seekers?

    Ridgway, Jason; Hickson, Louise; Lind, Christopher

    Hearing impairment is prevalent in older adults. Motivation is important in people's choice to seek help for their hearing and whether to adopt or not adopt hearing aids. To investigate associations between sociodemographic and audiometric characteristics and autonomous and controlled motivation among a sample of hearing help-seekers. A quantitative approach was taken for this cross-sectional cohort study. A total of 253 adult first-time hearing help-seekers were recruited to the study. Participants provided sociodemographic information and completed questionnaires adapted from self-determination theory that measured autonomous motivation (motivation that originates from within the self and is aligned with personal values and beliefs) and controlled motivation (motivation that stems from external pressures such as rewards or punishment, or conflicted inner feelings such as guilt or shame). Participants with higher autonomous motivation scores were younger, wanted hearing aids more, and reported greater hearing difficulty in everyday life than those with lower scores. Participants with higher controlled motivation scores were more often referred to the service by others and wanted hearing aids more than those with lower controlled motivation scores. Controlled motivation scores were not associated with perceptions of hearing difficulty in everyday life. Relationships among motivation and sociodemographic factors highlight the importance of characterizing autonomous and controlled motivation in first-time hearing help-seekers. Attention to personal characteristics in order to understand motivational processes involved in rehabilitation decisions such as hearing aid adoption may aid in consultations.

    Full Text Available Abstract Background Somatisation is particularly challenging in multicultural contexts where patients and physicians often differ in terms of their illness-related beliefs and practices and health care expectations. This paper reports on a exploratory study aimed at better understanding how asylum seeker and refugee patients from the former country of Yugoslavia who were identified by their physicians as somatising make sense of their suffering. Methods We conducted semi-structured interviews with 26 asylum seeker and refugee patients from the former country of Yugoslavia who attended the general medicine outpatient clinic of a Swiss teaching Hospital and were identified as presenting with somatisation. Interviews explored patients' illness perspectives and health care expectations. Interviews were audio taped, transcribed verbatim and analyzed to identify key themes in patients' narratives. Results Patients attributed the onset of symptoms to past traumatic experiences and tended to attribute their persistence to current living conditions and uncertain legal status. Patients formulated their suffering in both medical and social/legal terms, and sought help from physicians for both types of problems. Conclusion Awareness of how asylum seeker and refugee patients make sense of their suffering can help physicians to better understand patients' expectations of the clinical encounter, and the particular nature and constraints of the patient-provider relationship in the context of asylum.

    This study examined the relationships between youth and parental sensation-seeking, peer influence, parental monitoring and youth risk involvement in adolescence using structural equation modeling. Beginning in grade-six, longitudinal data were collected from 543 students over three years. Youth sensation-seeking in grade six contributed to risk involvement in early adolescence (grades six and seven) indirectly through increased peer risk influence and decreased parental monitoring but did not have a direct contribution. It contributed directly and indirectly to risk involvement in middle adolescence (grades eight and nine). Parent sensation-seeking at baseline was positively associated with peer risk influence and negatively associated with parental monitoring; it had no direct effect on adolescent risk involvement. Parental monitoring buffers negative peer influence on adolescent risk involvement. Results highlight the need for intervention efforts to provide normative feedback about adolescent risky behaviors and to vary among families in which parents and/or youth have high sensation-seeking propensities.

    Drawing upon a sample of 400 female high school students in Tehran, Iran, the present study examines the mediating role of social skills and sensation seeking in the relationship between trait emotional intelligence and school adjustment in adolescent girls. Statistical analysis revealed positive correlations between trait emotional intelligence and school adjustment; trait emotional intelligence and social skills; and social skills and school adjustment. The study also revealed a negative correlation between trait emotional intelligence and sensation seeking, as well as sensation seeking and school adjustment. In addition, the data provided a good fit to the hypothesized model of the mediating role of social skills and sensation seeking in the relationship between trait emotional intelligence and school adjustment.

    2004-04-01

    To investigate intraoperative perception and sensation during Laser in situ Keratomileusis (LASIK). Sixty patients with uneventful LASIK were included. All procedures were performed by one surgeon with one technique. Any patient with intra-operative complications was excluded. The patients were asked to fill in the subjective evaluation form regarding their perception and sensation during the operation. Twenty-nine patients (48%) reported no pain and twenty-six patients (43%) reported no burning sensation during the surgery. Nineteen patients (32%) reported no light perception during the suction period of microkeratome. There was no correlation between duration of the suction and no light perception (R2 0.01). Thirty-four patients (56%) reported no trouble in maintaining visual fixation at the red light during the laser treatment. Ten patients (16%) reported they could clearly see the movement during the surgery and 5 out of 10 patients (50% of 16%) reported visual frightening. Fifty cases (84%) reported no visual frightening during the surgery after reassurance of the visual experience by the surgeon before the surgery. Patients undergoing LASIK may experience different visual perceptions. Reassurance of the intraoperative perception and sensation before the surgery can reduce the visual frightening.

    Full Text Available Fatigue is an indispensable bioalarm to avoid exhaustive state caused by overwork or stresses. It is necessary to elucidate the neural mechanism of fatigue sensation for managing fatigue properly. We performed H2O  15 positron emission tomography scans to indicate neural activations while subjects were performing 35-min fatigue-inducing task trials twice. During the positron emission tomography experiment, subjects performed advanced trail-making tests, touching the target circles in sequence located on the display of a touch-panel screen. In order to identify the brain regions associated with fatigue sensation, correlation analysis was performed using statistical parametric mapping method. The brain region exhibiting a positive correlation in activity with subjective sensation of fatigue, measured immediately after each positron emission tomography scan, was located in medial orbitofrontal cortex (Brodmann's area 10/11. Hence, the medial orbitofrontal cortex is a brain region associated with mental fatigue sensation. Our findings provide a new perspective on the neural basis of fatigue.

  6. The association of hand preference and sensation seeking behavior.

    Science.gov (United States)

    Kuderer, Sonja; Kirchengast, Sylvia

    Although the human body shows a superficial symmetry, the disparate functions and skills of both body halves lead to an asymmetrical use. As a result, lateral preferences are detectable, which also include the favoured use of one hand ('handedness'). The collection of questionnaire data on sensation seeking and the conduction of behavioral handedness tasks by 55 research participants enabled the investigation of the interaction of handedness and sensation seeking. For this procedure the age-homogeneous study population is divided according to the Handedness-Index (HI) - a calculated value, indicating the practical hand preference. The results reveal a stronger lateralization in right-handed participants as well as a difference in the mean value of hand use in the three handedness groups. Sensation seeking behavior shows significant negative correlations with age as well as with the HI. Higher scores of left-handers in Experience Seeking (ES), Sensation Seeking (SS) as well as in Thrill and Adventure Seeking (TAS) indicate a larger risk investment in this handedness group. Hence, the results of this study suggest that handedness is a strong indicator of risk behavior.

    2007-01-01

    It has since long been known, from everyday experience as well as from animal and human studies, that psychological processes-both affective and cognitiveexert an influence on gastrointestinal sensorimotor function. More specifically, a link between psychological factors and visceral hypersensitivity has been suggested,mainly based on research in functional gastrointestinal disorder patients. However, until recently, the exact nature of this putative relationship remained unclear,mainly due to a lack of non-invasive methods to study the (neurobiological) mechanisms underlying this relationship in non-sleeping humans. As functional brain imaging, introduced in visceral sensory neuroscience some 10 years ago, does provide a method for in vivo study of brain-gut interactions, insight into the neurobiological mechanisms underlying visceral sensation in general and the influence of psychological factors more particularly,has rapidly grown. In this article, an overview of brain imaging evidence on gastrointestinal sensation will be given, with special emphasis on the brain mechanisms underlying the interaction between affective & cognitive processes and visceral sensation. First, the reciprocal neural pathways between the brain and the gut (braingut axis) will be briefly outlined, including brain imaging evidence in healthy volunteers. Second, functional brain imaging studies assessing the influence of psychological factors on brain processing of visceral sensation in healthy humans will be discussed in more detail.Finally, brain imaging work investigating differences in brain responses to visceral distension between healthy volunteers and functional gastrointestinal disorder patients will be highlighted.

    Seven male students were exposed to four varied air temperature environments: hot (37 degrees C) to neutral (27 degrees C) (HN), neutral to hot (NH), cool (17 degrees C) to neutral (CN), and neutral to cool (NC). The air temperature was maintained at the first condition for 20 min, then was changed to the second condition after 15 min and was held there for 20 min. Each subject wore a T-shirt, briefs, trunks, and socks. Each sat on a chair and was continuously evaluated for thermal sensation, thermal comfort, and air velocity sensation. Some physiological and thermal parameters were also measured every 5 s during the experiment. The correlation between thermal sensation and skin temperature at 15 sites was found to be poor. The subjects felt much warmer during the rising phase of the air temperature (CN, NH) than during the descending phase (HN, NC) at a given mean skin temperature. However, thermal sensation at the same heat flux or at the same value of the difference between skin and air temperature (delta(Tsk - Ta)) was not so different among the four experimental conditions, and the correlation between thermal sensation and heat flux or delta(Tsk - Ta) was fairly good. The multiple regression equation of the thermal sensation (TS) on 15 sites of skin temperature (Tsk; degrees C) was calculated and the coefficient of determination (R*2) was found to be 0.656. Higher coefficients of determination were found in the equations of thermal sensation for the heat flux (H; kcal.m-2.h-1) at the right and left thighs of the subjects and on delta(Tsk - Ta) (degrees C) at 4 sites. They were as follows: TS = 2.04 - 0.016 Hright - 0.036 Hleft; R*2 = 0.717, TS = 1.649 + 0.013 delta(Tsk - Ta)UpperArm - 0.036 delta(Tsk - Ta)Chest - 0.223 delta(Tsk - Ta)Thigh-0.083 delta(Tsk - Ta)LowerLeg; R*2 = 0.752, respectively.

    To assess gender-based violence and mental health outcomes among a population of female urban refugees and asylum seekers. In a questionnaire-based, cross-sectional study conducted in 2010 in Kampala, Uganda, a study team interviewed a stratified random sample of female refugees and asylum seekers aged 15-59 years from the Democratic Republic of Congo and Somalia. Questionnaires were used to collect information about recent and lifetime exposure to sexual and physical violence, and symptoms of depression and post-traumatic stress disorder (PTSD). Among the 500 women selected, 117 (23.4%) completed interviews. The weighted lifetime prevalences of experiencing any (physical and/or sexual) violence, physical violence, and sexual violence were 77.5% (95% CI 66.6-88.4), 76.2% (95% CI 65.2-87.2), and 63.3% (95% CI 51.2-75.4), respectively. Lifetime history of physical violence was associated with PTSD symptoms (Pviolence (P=0.014). Overall, 112 women had symptoms of depression (weighted prevalence 92.0; 95% CI 83.9-100) and 83 had PTSD symptoms (weighted prevalence 71.1; 95% CI 59.9-82.4). Prevalences of violence, depression, and PTSD symptoms among female urban refugees in Kampala are high. Additional services and increased availability of psychosocial programs for refugees are needed. Published by Elsevier Ireland Ltd.

    2014-01-01

    In a human rights based approach, the Parliamentary Assembly of the Council of Europe has recently released a resolution about migrants and refugees and the fight against HIV (1). It states that "an HIV positive migrant should never be expelled when it is clear that he will not receive adequate health care and assistance in the country to which he is being sent back. To do otherwise would amount to a death sentence for that person." Nevertheless, in Belgium, for the last 2 years, none of the HIV-infected migrants in care in the AIDS Reference Centers (ARC) received the right to stay in Belgium for medical reasons. We identified all HIV-infected asylum seekers in care between 1 July 2012 and 1 July 2014 in the ARC of Charleroi, Belgium, and we analyzed their medical and social files. Among the 302 patients in active follow up in our ARC, 45 HIV positive asylum seekers were in care during the last 2 years. Male/female ratio was 0/96. Mean age was 35 years. Countries of origin and reasons for migration are detailed in the Table 1. 18% (8/45) knew their seropositivity before arriving in Europe. All the patients introduced an asylum request, 29 (64%) have received a negative answer and an order to leave the territory, 4 (9%) were regularized for non-medical reasons (see Table 1), 4 (9%) are waiting for an answer and for 8 (18%) outcome is unknown due to lost follow up (LFU). 31 (69%) patients have also introduced a request to stay for medical reasons: 18 (58%) have received a refusal, 7 (23%) are still waiting for an answer, and 6 (19%) are LFU. Only 23 (51%) patients are still in care in our ARC on 1 July 2014 (see Table 1). The immigration office bases its decisions on availability of the treatment in the country even if accessible only to a limited number of patients. Decisions taken by the Belgian authorities for the last two years concerning HIV-infected asylum seekers do not guarantee the continuity of care of those patients and push them towards illegality.

    Full Text Available Croatia’s accession to the EU has brought new challenges and issues in researching and analysing migration flows and trends as well as attitudes and perceptions of real and potential newcomers. The aim of this paper is to explore attitudes of the residents of the two most easterly Croatian counties towards two distinct categories of newcomers: immigrant workers and asylum seekers. The research was conducted shortly after Croatia’s entry into the EU, in September 2013, and the presented data are a part of a larger survey that included various migration and ethnicity issues. The survey was applied on a convenience sample of 1 110 adult respondents in two counties: Osijek-Baranja and Vukovar-Srijem. Data were analysed in a series of multivariate procedures. Results indicated significant perceptions of immigrant workers within the dimension of cultural threat, along with the expression of a considerable degree of social distance towards them. Asylum seekers were further perceived as a security and economic threat. Within two analysed regression models, the effects on attitudes towards immigrant workers and asylum seekers were similar. Among the spectrum of socio-demographic variables, a statistically significant effect on both dependent variables came from age and political orientation, indicating that older and politically right-oriented respondents expressed more negative attitudes towards both groups. Among other socio-demographic variables, education was significant in predicting attitudes towards immigrant workers, while ethnicity was significant in predicting the attitudes towards asylum seekers. The second model analysed the effect of selected political attitudes and value orientations resulting in significant prediction of negative attitudes towards both groups by pronounced conservativism, support of aggression and submission, social-dominance, dominant submissive authoritarianism and social alienation, rejecting socially oriented

    Full Text Available Traumatised asylum seekers and refugees are clinically considered a complex population. Discussion exists on whether with this population treatment guidelines for post-traumatic stress disorder (PTSD should be followed and Trauma-Focused Cognitive-Behavioural Therapy (TF-CBT or Eye Movement Desensitisation and Reprocessing (EMDR should be applied, or whether a phased model starting with stabilisation is preferable. Some clinicians fear that trauma-focused interventions may lead to unmanageable distress or may be ineffective. While cognitive-behavioural interventions have been found to be effective with traumatised refugees, no studies concerning the efficacy of EMDR with this population have been conducted as yet.In preparation for a randomised trial comparing EMDR and stabilisation with traumatised refugees, a pilot study with 20 participants was conducted. The objective was to examine feasibility of participation in a randomised trial for this complex population and to examine acceptability and preliminary efficacy of EMDR.Participants were randomly allocated to 11 sessions of either EMDR or stabilisation. Symptoms of PTSD (SCID-I, HTQ, depression and anxiety (HSCL-25, and quality of life (WHOQOL-BREF were assessed at pre- and post-treatment and 3-month follow-up.Participation of traumatised refugees in the study was found feasible, although issues associated with complex traumatisation led to a high pre-treatment attrition and challenges in assessments. Acceptability of EMDR was found equal to that of stabilisation with a high drop-out for both conditions. No participants dropped out of the EMDR condition because of unmanageable distress. While improvement for EMDR participants was small, EMDR was found to be no less efficacious than stabilisation. Different symptom courses between the two conditions, with EMDR showing some improvement and stabilisation showing some deterioration between pre-treatment and post-treatment, justify the conduct

    Using dichotic signals presented by headphone, stimulus onset dominance (the precedence effect) for lateralization at low sensation levels was investigated for five normal hearing subjects. Stimuli were based on 2400-Hz low pass filtered 5-ms noise bursts. We used the paradigm, as described by Aoki and Houtgast (Hear. Res., 59 (1992) 25-30) and Houtgast and Aoki (Hear. Res., 72 (1994) 29-36), in which the stimulus is divided into a leading and a lagging part with opposite lateralization cues (i.e. an interaural time delay of 0.2 ms). The occurrence of onset dominance was investigated by measuring lateral perception of the stimulus, with fixed equal duration of leading and lagging part, while decreasing absolute signal level or adding a filtered white noise with the signal level set at 65 dBA. The dominance of the leading part was quantified by measuring the perceived lateral position of the stimulus as a function of the relative duration of the leading (and thus the lagging) part. This was done at about 45 dB SL without masking noise and also at a signal-to-noise ratio resulting in a sensation level of 10 dB. The occurrence and strength of the precedence effect was found to depend on sensation level, which was decreased either by lowering the signal level or by adding noise. With the present paradigm, besides a decreased lateralization accuracy, a decrease in the precedence effect was found for sensation levels below about 30-40 dB. In daily-life conditions, with a sensation level in noise of typically 10 dB, the onset dominance was still manifest, albeit degraded to some extent.

    With a large number of forcibly displaced people seeking safety, the EU is facing a challenge in maintaining solidarity. Europe has seen millions of asylum seekers crossing European borders, the largest number of asylum seekers since the second world war. Endemic diseases and often failing health systems in their countries of origin, and arduous conditions during transit, raise questions around how to meet the health needs of this vulnerable population on arrival in terms of screening, vaccination, and access to timely and appropriate statutory health services. This paper explores the potential role of the principle of reciprocity, defined as the disposition 'to return good in proportion to the good we receive, and to make reparations for the harm we have done', as a mid-level principle in infectious disease screening policies. More than half of the European countries implemented screening programmes for newly arrived asylum seekers. Screening may serve to avoid potential infectious disease risks in the receiving countries as well as help identify health needs of asylum seekers. But screening may infringe upon basic rights of those screened, thus creating an ethical dilemma. The use of the principle of reciprocity can contribute to the identification of potential improvements for current screening programmes and emphasizes the importance of certain rights into guidelines for screening. It may create a two way moral obligation, upon asylum seekers to actively participate in the programme, and upon authorities to reciprocate the asylum seekers' participation and the benefits for the control of public health. The authors argue that the reciprocity principle leads to a stronger ethical justification of screening programmes and help achieve a balance between justifiable rights claims of the host population and the asylum seekers. The principle deserves a further and more thorough exploration of its potential use in the field of screening, migration and infectious

    Phantom sensations are somatic phenomena arising from denervated parts of the body. There is very little research, and much diagnostic confusion, regarding such experiences in people with spinal cord injuries. In the case of 'complete' spinal cord lesions, phantom experiences may challenge, and indeed, contradict, the understanding that both clinicians and patients have of such injuries. This paper seeks to provide a better understanding of such 'phantom' sensations in spinal cord injury. We used grounded theory methods to explore 'phantom' sensations as experienced by individuals with complete (ASIA A) spinal lesions. Eight people with complete lesions, who were selected through theoretical sampling, participated in a semi-structured interview. Emergent themes included injury context, sensations experienced, the meaning of sensations, body connectivity, attitude and communication about sensations. Our results provide an enhanced understanding of the embodied experience of phantom sensations, and important insights regarding self-construction and rehabilitative processes in people with spinal cord injury who experience such anomalous sensations.

    Sensation seeking is strongly associated with cigarette use in adolescents. However, few studies have investigated its relationship with adolescent e-cigarette use. This study examined cross-sectional and longitudinal associations between sensation seeking and a variety of e-cigarette use behaviors among Texas adolescents. This study utilized two waves of data collected 6months apart through the Texas Adolescent Tobacco and Marketing Surveillance System (TATAMS) in 2014-2015 (n=2,488/N=461,069). TATAMS employs a complex probability-sampling design and is representative of students in 6th, 8th and 10th grades from five counties surrounding the four largest cities in Texas (Houston, Dallas/Ft. Worth, San Antonio, Austin). Weighted multivariable logistic regression was used to examine the cross-sectional and longitudinal associations between sensation seeking and susceptibility to e-cigarette use, ever e-cigarette use, and current (past 30day) e-cigarette use. In the cross-sectional analyses, higher mean sensation seeking scores were associated with higher odds of both susceptibility to e-cigarette use and ever e-cigarette use (AOR=1.25, 95% CI=1.07, 1.47; AOR=1.24, 95% CI=1.08, 1.43, respectively). For the longitudinal analyses, only the association between higher mean sensation seeking scores and transition to ever e-cigarette use remained statistically significant (AOR=1.45, 95% CI=1.01, 2.08). There were no significant associations between sensation seeking and current e-cigarette use in either the cross-sectional or longitudinal analyses. Higher sensation seeking scores were consistently and significantly related to experimentation with e-cigarette use among Texas adolescents. Future interventions (e.g., communication campaigns) should target high sensation seeking adolescents to reduce initiation of e-cigarette use among this population. Copyright © 2017.

    When studying 750 psychiatric in-patients with psychoses of various diagnostic groups, the symptoms of voice sensations and vibration feelings could only be found among patients with paranoid schizophrenia. In addition, these symptoms were located exclusively in body areas that are involved in the peripheral motor production of voice and speech (areas of head, throat, thorax). In 11 of 15 such cases that could be identified, the sensations of voices and vibrations occurred simultaneously and in identical body parts; in the remaining 4 cases only voices without vibration sensations were reported. Therefore these symptoms can be considered as highly specific for schizophrenia. According to the terminology of Bleuler these two symptoms are because of their rareness to be taken as accessoric symptoms; according to the terminology of Kurt Schneider they have the value of first rank symptoms because of their highly diagnostic specifity for schizophrenia. The pathogenesis of these symptoms is on the one hand discussed under the perspective of language development and the changing function of language for behaviour control; on the other hand, the pathogenesis of these symptoms is discussed from the viewpoint of cybernetic, or neurophysiological-neuroanatomical foundation of speech production and speech control. Both models of explanation have in common that the ideational component of speech is noticed as acustic halluzinations and the motor proprioceptive part of speech is noticed as sensation of vibrations, both in a typically schiphrenic manner, i.e. dissociated and ego-alienated.

    Distress is a modifiable risk factor for smoking maintenance. This study aimed to assess racial/ethnic differences in distress pre- and post-cognitive-behavioral therapy (CBT) for smoking cessation, and relations with abstinence. Analyses of variance and logistic regressions were conducted. University-based smoking cessation laboratory in South Florida, USA. The sample comprised 234 treatment-seekers recruited from the community (18% white, 60% African American and 22% Hispanic). All participants received eight sessions of group CBT plus 8 weeks of transdermal nicotine patches (TNP). Demographics and smoking history [baseline], perceived stress and depressive symptoms [baseline and end of therapy (EOT)], carbon monoxide-verified 7-day point prevalence abstinence (p.p.a.) at EOT, 3 months post-CBT (primary outcome) and 6 months (self-report). Compared with whites, African Americans reported greater baseline perceived stress (P = 0.03) and depressive symptoms (P = 0.06); no EOT differences were found. African Americans (P perceived stress reduction, and African Americans reported greater reductions in depressive symptoms (P perceived stress (adjusted odds ratio (AOR) = 0.93 (0.89-0.98)) and depressive symptoms [AOR = 0.96 (0.93-0.99)] were associated inversely with 7-day p.p.a. at 3 months. Reductions in perceived stress [AOR = 0.93 (0.89-0.98)] and depressive symptoms at the EOT [AOR = 0.96 (0.93-0.99)] were associated with cessation, such that reduced distress increased the odds of abstinence. The interactions between race/ethnicity and distress on 7-day p.p.a. were not significant at any assessment point. Among smokers in Florida, USA, racial/ethnic differences in distress before starting cognitive-behavioral therapy for smoking cessation were eliminated at the end of treatment, driven by improvements among African Americans and Hispanics. High levels of distress were associated with reduced odds of abstinence through 6

    Objective. The aim of this study was to compare impulsivity and risky decision making among HIV-positive and negative heroin dependent persons. Methods. We compared different dimensions of impulsivity and risky decision making in two groups of 60 HIV-positive and 60 HIV-negative male heroin dependent persons. Each group was comprised of equal numbers of current (treatment seeker) and former (abstinent) heroin addicts. Data collection tools included Balloon Analogue Risk Task (BART), Iowa Gambling Task (IGT), Barratt Impulsiveness Scale (BIS), and Zuckerman Sensation Seeking Scale (SSS). Results. In SSS, comprised of four subscales including thrill and adventure seeking (TAS), experience seeking (ES), disinhibition (DIS), and boredom susceptibility (BS), there was a borderline difference in DIS (P = 0.08) as HIV-positive group scored higher than HIV-negative group. Also, ES and total score were significantly higher among HIV-positive patients. In BART, HIV-positive subjects scored higher in risk taking than HIV-negative subjects as reflected in higher Average Number of puffs in Successful Balloons (ANSB). In BIS, HIV-positive group scored significantly higher in cognitive impulsivity (CI) (P = 0.03) and nonplanning impulsivity (NPI) (P = 0.05) in comparison to HIV-negative group. Also, current heroin addicts scored significantly higher in NPI compared to former addict HIV-negative participants (P = 0.015). IGT did not show any significant difference between groups. Conclusion. Higher levels of impulsivity and risk taking behaviors among HIV-positive heroin addicts will increase serious concerns regarding HIV transmission from this group to other opiate dependents and healthy people.

    Surface texture sensation is significant for business success, in particular for solid surfaces for most of the materials; including foods. Mechanisms of roughness perception are still unknown, especially under different conditions such as lubricants with varying viscosities, different temperatures, or under different force loads during the observation of the surface. This work aims to determine the effect of those unknown factors, with applied sensory tests on 62 healthy participants. Roughness sensation of fingertip was tested under different lubricants including water and diluted syrup solutions at room temperature (25C) and body temperature (37C) by using simple pair-wise comparison to observe the just noticeable difference threshold and perception levels. Additionally, in this research applied force load during roughness observation was tested with pair-wise ranking method to illustrate its possible effect on human sensation. Obtained results showed that human's capability of roughness discrimination reduces with increased viscosity of the lubricant, where the influence of the temperature was not found to be significant. Moreover, the increase in the applied force load showed an increase in the sensitivity of roughness discrimination. Observed effects of the applied factors were also used for estimating the oral sensation of texture during eating. These findings are significant for our fundamental understanding to texture perception, and for the development of new food products with controlled textural features. Texture discrimination ability, more specifically roughness discrimination capability, is a significant factor for preference and appreciation for a wide range of materials, including food, furniture, or fabric. To explore the mechanism of sensation capability through tactile senses, it is necessary to identify the relevant factors and define characteristics that dominate the process involved. The results that will be obtained under these principles

  4. The concept of peripheral modulation of bladder sensation.

    It is recognized that, as the bladder fills, there is a corresponding increase in sensation. This awareness of the volume in the bladder is then used in a complex decision making process to determine if there is a need to void. It is also part of everyday experience that, when the bladder is full and sensations strong, these sensations can be suppressed and the desire to void postponed. The obvious explanation for such altered perceptions is that they occur centrally. However, this may not be the only mechanism. There are data to suggest that descending neural influences and local factors might regulate the sensitivity of the systems within the bladder wall generating afferent activity. Specifically, evidence is accumulating to suggest that the motor-sensory system within the bladder wall is influenced in this way. The motor-sensory system, first described over 100 years ago, appears to be a key component in the afferent outflow, the afferent "noise," generated within the bladder wall. However, the presence and possible importance of this complex system in the generation of bladder sensation has been overlooked in recent years. As the bladder fills the motor activity increases, driven by cholinergic inputs and modulated, possibly, by sympathetic inputs. In this way information on bladder volume can be transmitted to the CNS. It can be argued that the ability to alter the sensitivity of the mechanisms generating the motor component of this motor-sensory system represents a possible indirect way to influence afferent activity and so the perception of bladder volume centrally. Furthermore, it is emerging that the apparent modulation of sensation by drugs to alleviate the symptoms of overactive bladder (OAB), the anti-cholinergics and the new generation of drugs the β 3 sympathomimetics, may be the result of their ability to modulate the motor component of the motor sensory system. The possibility of controlling sensation, physiologically and pharmacologically, by

    A growing literature suggests that the characteristics of sensation seeking and reality distortion expressed in schizophrenia share several mechanisms. In a previous study, the comparison of patients with high vs. low reality distortion using event-related potentials (ERPs) recorded in a recognition memory task for unfamiliar faces identified neural and cognitive anomalies specifically related to the expression of these symptoms. As a follow-up, this study investigated the ERP correlates of sensation seeking in schizophrenia using the same recognition memory protocol. ERPs have been recorded in controls (N=21) and schizophrenia patients separated into high (HSS; N=13) and low (LSS; N=17) scorers according to Zuckerman's Sensation Seeking Scale. The results show a reduced P2a that was found unrelated to reality distortion in the previous study of reality distortion. It identifies interference inhibition impairment as being specifically related to sensation seeking. On the other hand, HSS scorers display enhanced fronto-central and normal P600 effects also found in high reality distortion patients. These results indicate inappropriate context processing and mnemonic binding common to sensation seeking and reality distortion. LSS scorers also display a reduced temporal N300 similar to that found in low reality distortion patients. This anomaly could reflect the lower reactivity to emotionally significant stimuli that underlies anhedonia symptoms. Finally, the N400 effect and a late frontal effect are found in both HSS and LSS. Since they were unrelated to reality distortion, these indices have been related to basic aspects of schizophrenia, e.g., deficient knowledge integration, or other mechanisms, e.g. anxiety or impulsivity. In summary, the present study examines the strategy of investigating variables, such as temperamental characteristics, in addition to symptoms, to show how discrete impairments may contribute to the expression of the illness.

    Can photographs of scars serve as evidence of torture? Amnesty International's Medical Examination Group in the Netherlands (AI-MEG) has, for more than a decade, been photographing torture scars to supplement the testimonies of asylum seekers who have been denied refuge. AI-MEG only intervenes at this point, when asylum seekers face extradition. Proving allegations of torture is of vital importance, as asylum seekers face rising anti-immigrant sentiment in European countries. All victims examined by AI-MEG present a combination of mental, physical and emotional scars. We summarize five cases where AI-MEG used photography in their medical examinations, and consider the ethical role physicians play in helping asylum seekers obtain refuge. Though photographs cannot capture all forms of trauma, as visual documents, they are a compelling form of concrete evidence of torture. In this way, photographs complement verbal testimonies and help doctors and immigration authorities to see and understand physical scars left by various forms of torture. AI-MEG explains in medical terms the connections between the visible late sequelae of torture and victims' testimonies. They then assess whether or not the physical scars are consistent with the forms of torture recounted by victims, using the terminology of the Istanbul Protocol (1999), the United Nations-adopted manual of guidelines that explains how to document torture. This paper outlines the medical examination process and argues for the use of photography as medical evidence on behalf of asylum seekers. Copyright 2010 Elsevier Ltd. All rights reserved.

  9. The Politics of Gender Asylum in the U. S.: Protection of Women Asylum Seekers in the Context of Global Inequalities

    Marina Matešić

    2014-04-01

    Full Text Available This article examines the changes towards more gender-sensitive interpretations of refugee status in international and national asylum laws and policies within the context of contemporary and historical global power relations. It also analyzes the changes in the language that can be found in the international UNHCR guidelines for the protection of women asylum seekers, U.S. national guidelines for assessing gender-related asylum claims, and recent U.S. court decisions assessing the gendered claims of women. Among the analyzed court cases, the focus is on the 2005 Mohammed case due to its problematic court decision and legal interpretations. Finding the Western countries’ instrumentalization of the international refugee protection system crucial for understanding the contemporary asylum system and women asylum seekers, the argument connects the historical conditions with the way in which the protection of women refugees from “cultural” gendered violence has been articulated in asylum politics in the U.S. The author’s overall findings are that international law, governmental organizations, and liberal women’s human rights NGOs have shaped the international and national legal protection of (women asylum seekers in such a way that it reproduces global inequalities in its representation of “Third World” women and their culture, uses women asylum seekers fleeing from violence for the purpose of exercising Western cultural superiority, and covers up the restrictive and racist Western asylum politics towards immigrants and asylum seekers.

    Full Text Available As refugee and asylum seeker numbers increase in Australia, their effective integration into society is facilitated by inclusion in social, economic and community life. This systematic review of the literature explored community-based programs that contribute to inclusion and social participation of refugees and asylum seekers in Australia. Four scholarly databases were searched for articles published between 2007 and 2017 resulting in five articles which met inclusion criteria. Although the studies identified were of variable quality, the findings suggest a number of factors that facilitate program effectiveness. These included where: (a English language and communications skills were considered; (b programs built on refugees’ own skills and experience prior to resettlement; (c volunteers and mentors were involved; and (d participants engaged in diverse projects that enabled new connections. The review highlights the paucity of well-researched interventions that build social inclusion of refugees and asylum seekers in Australia. Emerging evidence suggests that community-based programs can positively increase social inclusion and connectedness amongst refugees and asylum seekers. Additional well-designed programs and evaluation of such programs are needed to better understand and identify effective interventions targeting social inclusion of refugees and asylum seekers.

    1997-10-01

    During the final down-thrust of a pigeon's head, the eyes are closed gradually, a response that was thought to block visual input. This phase of pecking was therefore assumed to be under feed-forward control exclusively. Analysis of high resolution video-recordings showed that visual information collected during the down-thrust of the head could be used for 'on-line' modulations of pecks in progress. We thus concluded that the final down-thrust of the head is not exclusively controlled by feed-forward mechanisms but also by visual feedback components. We could further establish that as a rule the eyes are never closed completely but instead the eyelids form a slit which leaves a part of the pupil uncovered. The width of the slit between the pigeon' eyelids is highly sensitive to both, ambient luminance and the visual background against which seeds are offered. It was concluded that eyelid slits increase the focal depth of retinal images at extreme near-field viewing-conditions. Applying pharmacological methods we could confirm that pupil size and eyelid slit width are controlled through conjoint neuronal mechanisms. This shared neuronal network is particularly sensitive to drugs that affect dopamine receptors.

    Due to the high rates of epidural failure (3-32%), novel techniques are required to objectively assess the successfulness of an epidural block. In this study we therefore investigated whether thermographic temperature measurements have a higher predictive value for a successful epidural block when compared to the cold sensation test as gold standard. Epidural anesthesia was induced in 61 patients undergoing elective abdominal, thoracic or orthopedic surgery. A thermographic picture was recorded at 5, 10 and 15 min following epidural anesthesia induction. After 15 min a cold sensation test was performed. Epidural anesthesia is associated with a decrease in skin temperature. Thermography predicts a successful epidural block with a sensitivity of 54% and a PPV of 92% and a specificity of 67% and a NPV of 17%. The cold sensation test shows a higher sensitivity and PPV than thermography (97 and 93%), but a lower specificity and NPV than thermography (25 and 50%). Thermographic temperature measurements can be used as an additional and objective method for the assessment of the effectiveness of an epidural block next to the cold sensation test, but have a low sensitivity and negative predictive value. The local decrease in temperature as observed in our study during epidural anesthesia is mainly attributed to a core-to-peripheral redistribution of body heat and vasodilation.

    Outdoor urban areas are very important for cities and microclimate is a critical parameter in the design process, contributing to thermal comfort which is important for urban developments. The research presented in this paper is part of extensive field surveys conducted in Athens aimed at investigating people's thermal sensation in a Mediterranean city. Based on 2313 questionnaires and microclimatic data the current work focuses on the relative frequencies of people's evaluation of the thermal along with the sun and wind sensations between two seasons trying to identify the seasonal differences in thermal sensation. The impact of basic meteorological factors on thermal discomfort with respect to season are also examined, as well as the use of the outdoor environment. Results show that psychological adaptation is an important contributing factor influencing perception of the thermal environment between seasons. In addition, the thermal sensation votes during the cool months show that individuals are satisfied to a great extend with the thermal environment whereas the combination of high air temperature, strong solar radiation and weak wind lead to thermal discomfort during summertime. As far as the appropriate urban design in the Mediterranean climate is concerned, priority should be given to the warm months of the year.

    Sensation seeking, a personality trait, has been shown to predict engagement in high-risk behaviors. However, little is known regarding the impact of sensation seeking on substance use among street youth. We therefore sought to modify a sensation seeking scale (SSS) for use among this population. Street youth from the Vancouver-based At-Risk Youth Study (n = 226) completed the modified SSS. Exploratory and confirmatory factor analysis (EFA/CFA) were undertaken to establish the scale's dimensionality and internal validity. The association between SSS score and injection-related behaviors was tested using generalized estimating equation analysis. EFA results indicated scale unidimensionality. The comparative fit index (CFI) suggested acceptable fit (CFI = 0.914). In multivariate analysis, sensation seeking was independently associated with injection drug use, crystal methamphetamine use, polysubstance use, and binge drug use (all p < 0.05). Our findings provide preliminary support for the use of the modified SSS among street youth.

    Full Text Available This research aimed to explore a relation between Body image (PSPP and Sensation Seeking (SSS-V and to determine gym-goers based on these entities. The research file (N = 182 consisted of gym-goers aged between 24 – 45. The comparison of the tests showed a weak relation (0.25 between PSPP and SST tests and also among the individual subscales. The comparison of men and women did not come up with any significant differences. In terms of Body image, the file showed above-average results, in the case of Sensation Seeking, its score was average. The outcome of our findings is that there is no marked relation between PSPP and SST and the same goes for men and women.

The risk definitions the subjects use have also been shown to be related to various educational interests. A related field of research has developed measures for Sensation Seeking personality trait, with four facets. Three independent groups of first year psychology students reported their normal definition of the word risk using one of three measurement formats. The results showed, e.g. that the typical open-ended response to the personal definition of risk was danger.

    The Anthropomorphic Robotic Testbed (ART) is an experimental prototype of a partly anthropomorphic, humanoid-size, mobile robot. The basic ART design concept provides for a combination of two-armed coordination, tactility, stereoscopic vision, mobility with navigation and avoidance of obstacles, and natural-language communication, so that the ART could emulate humans in many activities. The ART could be developed into a variety of highly capable robotic assistants for general or specific applications. There is especially great potential for the development of ART-based robots as substitutes for live-in health-care aides for home-bound persons who are aged, infirm, or physically handicapped; these robots could greatly reduce the cost of home health care and extend the term of independent living. The ART is a fully autonomous and untethered system. It includes a mobile base on which is mounted an extensible torso topped by a head, shoulders, and two arms. All subsystems of the ART are powered by a rechargeable, removable battery pack. The mobile base is a differentially- driven, nonholonomic vehicle capable of a speed >1 m/s and can handle a payload >100 kg. The base can be controlled manually, in forward/backward and/or simultaneous rotational motion, by use of a joystick. Alternatively, the motion of the base can be controlled autonomously by an onboard navigational computer. By retraction or extension of the torso, the head height of the ART can be adjusted from 5 ft (1.5 m) to 6 1/2 ft (2 m), so that the arms can reach either the floor or high shelves, or some ceilings. The arms are symmetrical. Each arm (including the wrist) has a total of six rotary axes like those of the human shoulder, elbow, and wrist joints. The arms are actuated by electric motors in combination with brakes and gas-spring assists on the shoulder and elbow joints. The arms are operated under closed-loop digital control. A receptacle for an end effector is mounted on the tip of the wrist and

  19. Relationship between oscillatory neuronal activity during reward processing and trait impulsivity and sensation seeking.

    Directory of Open Access Journals (Sweden)

    Gregor Leicht

    Full Text Available BACKGROUND: The processing of reward and punishment stimuli in humans appears to involve brain oscillatory activity of several frequencies, probably each with a distinct function. The exact nature of associations of these electrophysiological measures with impulsive or risk-seeking personality traits is not completely clear. Thus, the aim of the present study was to investigate event-related oscillatory activity during reward processing across a wide spectrum of frequencies, and its associations with impulsivity and sensation seeking in healthy subjects. METHODS: During recording of a 32-channel EEG 22 healthy volunteers were characterized with the Barratt Impulsiveness and the Sensation Seeking Scale and performed a computerized two-choice gambling task comprising different feedback options with positive vs. negative valence (gain or loss and high or low magnitude (5 vs. 25 points. RESULTS: We observed greater increases of amplitudes of the feedback-related negativity and of activity in the theta, alpha and low-beta frequency range following loss feedback and, in contrast, greater increase of activity in the high-beta frequency range following gain feedback. Significant magnitude effects were observed for theta and delta oscillations, indicating greater amplitudes upon feedback concerning large stakes. The theta amplitude changes during loss were negatively correlated with motor impulsivity scores, whereas alpha and low-beta increase upon loss and high-beta increase upon gain were positively correlated with various dimensions of sensation seeking. CONCLUSIONS: The findings suggest that the processing of feedback information involves several distinct processes, which are subserved by oscillations of different frequencies and are associated with different personality traits.

The cinematic gaze can produce sensations of shame and fear, by offering a sequence of varied “encounters” to which viewers can react, before we have been given a character onto which we can deflect them, thus bypassing the representational, narrative and even the sym...

  1. Pulse Width Affects Scalp Sensation of Transcranial Magnetic Stimulation.

    Peterchev, Angel V; Luber, Bruce; Westin, Gregory G; Lisanby, Sarah H

    Scalp sensation and pain comprise the most common side effect of transcranial magnetic stimulation (TMS), which can reduce tolerability and complicate experimental blinding. We explored whether changing the width of single TMS pulses affects the quality and tolerability of the resultant somatic sensation. Using a controllable pulse parameter TMS device with a figure-8 coil, single monophasic magnetic pulses inducing electric field with initial phase width of 30, 60, and 120 µs were delivered in 23 healthy volunteers. Resting motor threshold of the right first dorsal interosseus was determined for each pulse width, as reported previously. Subsequently, pulses were delivered over the left dorsolateral prefrontal cortex at each of the three pulse widths at two amplitudes (100% and 120% of the pulse-width-specific motor threshold), with 20 repetitions per condition delivered in random order. After each pulse, subjects rated 0-to-10 visual analog scales for Discomfort, Sharpness, and Strength of the sensation. Briefer TMS pulses with amplitude normalized to the motor threshold were perceived as slightly more uncomfortable than longer pulses (with an average 0.89 point increase on the Discomfort scale for pulse width of 30 µs compared to 120 µs). The sensation of the briefer pulses was felt to be substantially sharper (2.95 points increase for 30 µs compared to 120 µs pulse width), but not stronger than longer pulses. As expected, higher amplitude pulses increased the perceived discomfort and strength, and, to a lesser degree the perceived sharpness. Our findings contradict a previously published hypothesis that briefer TMS pulses are more tolerable. We discovered that the opposite is true, which merits further study as a means of enhancing tolerability in the context of repetitive TMS. Copyright © 2016 Elsevier Inc. All rights reserved.

    Intrapersonal touch is a powerful tool for communicating emotions and can among many things evoke feelings of eroticism and sexual arousal. The peripheral neural mechanisms of erotic touch signaling have been less studied. C tactile afferents (unmyelinated low-threshold mechanoreceptors), known to underpin pleasant aspects of touch processing, have been posited to play an important role. In two studies, we investigated the relationship between C tactile activation and the perception of erotic and pleasant touch, using tactile brushing stimulation. In total, 66 healthy subjects (37 women, age range 19-51 years) were examined. In study 1 (n = 20), five different stroking velocities were applied to the forearm and the inner thigh. The participants answered questions about partnership, mood, and touch. In study 2 (n = 46), the same five stroking velocities were applied to the forearm. The participants answered questions about partnership, touch, and sexuality. Both touch eroticism and pleasantness were rated significantly higher for C tactile optimal velocities compared with suboptimal velocities. No difference was found between the ratings of the thigh and the forearm. The velocity-dependent rating curves of pleasantness, intensity, and eroticism differed from each other. Pleasantness was best explained by a quadratic fit, intensity by a linear fit, and eroticism by both. A linear transformation of pleasantness and intensity predicted the observed eroticism ratings reliably. Eroticism ratings were negatively correlated with length of relationship. Touch was rated most erotic when perceived as pleasant and weak. In human hairy skin, perception of pleasantness is correlated with the firing rate of C tactile afferents, and perception of intensity is correlated with the firing rate of Aβ afferents. Accordingly, eroticism may be perceived most readily for touch stimuli that induce high activity in C tactile fibers and low activity in Aβ fibers. © 2015 International

    The purpose of this study was to investigate the relationship between subtypes of social anxiety and distorted cognition of bodily sensations. The package of questionnaires including the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS) was administered to 582 undergraduate students. To identify subtypes of social anxiety, cluster analysis was conducted using scores of the SPS and SIAS. Five clusters were identified and labeled as follows: Generalized type characterized by intense anxiety in most social situations, Non-anxious type characterized by low anxiety levels in social situations, Averaged type whose anxiety levels are averaged, Interaction anxiety type who feels anxiety mainly in social interaction situations, and Performance anxiety type who feels anxiety mainly in performance situations. Results of an ANOVA indicated that individuals with interaction type fear the negative evaluation from others regarding their bodily sensations whereas individuals with performance type overestimate the visibility of their bodily sensations to others. Differences in salient aspects of cognitive distortion among social anxiety subtypes may show necessity to select intervention techniques in consideration of subtypes.

    Full Text Available When one finger touches the other, the resulting tactile sensation is perceived as weaker than the same stimulus externally imposed. This attenuation of sensation could result from a predictive process that subtracts the expected sensory consequences of the action, or from a postdictive process that alters the perception of sensations that are judged after the event to be self-generated. In this study we observe attenuation even when the fingers unexpectedly fail to make contact, supporting a predictive process. This predictive attenuation of self-generated sensation may have evolved to enhance the perception of sensations with an external cause.

    We report two cases of louse-borne relapsing fever (LBRF) in young Somali asylum seekers having recently arrived to Finland. They had sought medical attention for a febrile illness. Blood smears were examined for suspected malaria, but instead, spirochete shaped bacteria were observed. The bacteria were confirmed as Borrelia recurrentis by PCR and sequencing. The patients survived, but their treatment was complicated by Jarisch-Herxheimer reaction. We conclude that LBRF must be considered as a diagnostic option in febrile refugees also in the northernmost parts of Europe. © 2016 APMIS. Published by John Wiley & Sons Ltd.

    2009-10-01

    The UK government has recently consulted on proposals to prohibit access to health care for some asylum seekers. This discussion paper considers the wider ethical, moral, and political issues that may arise from this policy. In particular, it explores the relationship between immigration and health and examines the impact of forced migration on health inequalities. It will be argued that it is both unethical and iniquitous to use health policy as a means of enforcing immigration policy. Instead, the founding principle of the NHS of equal access on the basis of need should be borne in mind when considering how to meet the needs of this population.

  11. The Impact of Externalization of Migration Controls on the Rights of Asylum Seekers and Other Migrants

    Full Text Available Wars, conflict, and persecution have forced more people to flee their homes and seek refuge and safety elsewhere than at any time since the end of World War II. As displaced people and other migrants increasingly move out of the conflict-ridden and less developed regions of their displacement and into relatively rich and stable regions of the world, the countries of destination are increasingly working to contain and even stem the migration flow before it reaches their shores. Perversely, countries that have developed generally rights-sensitive standards and procedures for assessing protection claims of asylum seekers within their jurisdictions have simultaneously established barriers that prevent migrants, including asylum seekers, from setting foot on their territories or otherwise triggering protection obligations. Consequently, those who would otherwise have been able to avail themselves of asylum procedures, social support, and decent reception conditions are often relegated to countries of first arrival or transit that have comparatively less capacity to ensure protection of human rights in accordance with international standards.This paper seeks to develop a working definition of the externalization of migration controls and how such externalization of the border implicates the human rights of migrants, and asylum seekers in particular. Although the majority of those migrants seeking legal protections stay in countries neighboring their own, hundreds of thousands continue their journeys in search of protection and stability in more distant states, including in the European Union, the United States, and Australia. In response to the significant increase in asylum seekers arriving at their borders, all three entities have significantly increased deterrence measures with the hopes of keeping new arrivals from entering. This paper will thus highlight a number of the most troubling externalization strategies used by the European Union, the

  12. Traces: making sense of urodynamics testing--Part 8: Evaluating sensations of bladder filling.

    Science.gov (United States)

    Gray, Mikel

    2011-01-01

    The "Traces" series discusses how the urodynamic clinician generates usable data from a filling cystometrogram (CMG). Part 8 focuses on the question, "What are the sensations of bladder filling?" Recent research suggests that sensations of bladder filling wax and wane from consciousness in healthy persons free of bothersome lower urinary tract symptoms. Because of its invasive and atypical nature when compared to daily life, multichannel urodynamics testing cannot reproduce the numerous and complex variables that influence bladder sensation in the healthy individual, making the evaluation of sensations of bladder filling a particularly challenging component of the filling CMG. Routine assessment of bladder sensations focuses on identification of three landmarks--first sensation of bladder filling, first desire to void, and a strong desire to void. A fourth sensation, bladder fullness or a compelling desire to void, is recommended. In addition to assessing these sensations, the urodynamic clinician must assess sensations indicating associated disease or disorders affecting lower urinary tract function, including urgency, pain, and atypical sensations. This assessment should be completed in the context of the results of one or more validated instruments used to measure bladder sensations.

    We examined the roles of sensation seeking, risk taking, and moral reasoning in the development of reactive and proactive aggression. Data were drawn from a multiethnic, longitudinal study of children from Switzerland (N = 1571; 52 % male; assessed annually over 6 years; 7-years-old at Time 1). At all 6 time points, teachers reported children's reactive and proactive aggression via questionnaire. Children's sensation seeking (at Time 1) and risk taking (at Time 2) were assessed with two interactive computer tasks and their moral reasoning was assessed at Time 2 in response to four hypothetical vignettes depicting moral transgressions. Parallel process Latent Class Growth Analysis (PP-LCGA) identified six dual trajectories of reactive and proactive aggression. Children with either childhood-limited or adolescent-onset aggression showed high sensation seeking. Children with persistent, high levels of both reactive and proactive aggression across time showed high levels of sensation seeking and risk taking, as well as low levels of moral reasoning. Children with only high risk taking were more likely to display moderate levels of aggression across time. These findings highlight the shared and differential roles of sensation seeking, risk taking, and moral reasoning in the dual development of reactive and proactive aggression from mid-childhood to early adolescence. We discuss implications for common and tailored strategies to combat these aggression subtypes.

    2012-01-01

    This manuscript investigates the analysis and modeling of vehicular thermal comfort parameters using a set of designed experiments aided by thermography measurements. The experiments are conducted using a full size climatic chamber to host the test vehicle, to accurately assess the transient and steady state temperature distributions of the test vehicle cabin. Further investigate the thermal sensation (overall and local) and the human comfort states under artificially created relative humidity scenarios. The thermal images are calibrated through a thermocouples network, while the outside temperature and relative humidity are manipulated through the climatic environmental chamber with controlled soaking periods to guarantee the steady state conditions for each test scenario. The relative humidity inside the passenger cabin is controlled using a Total Humidity Controller (THC). The simulation uses the experimentally extracted boundary conditions via a 3-D Berkeley model that is set to be fully transient to account for the interactions in the velocity and temperature fields in the passenger compartment, which included interactions from turbulent flow, thermal buoyancy and the three modes of heat transfer conduction, convection and radiation. The model investigates the human comfort by analyzing the effect of the in-cabin relative humidity from two specific perspectives; firstly its effect on the body temporal variation of temperature within the cabin. Secondly, the Local Sensation (LS) and Comfort (LC) are analyzed for the different body segments in addition to the Overall Sensation (OS) and the Overall Comfort (OC). Furthermore, the human sensation is computed using the Fanger model in terms of the Predicted Mean Value (PMV) and the Predicted Percentage Dissatisfied (PPD) indices. The experimental and simulation results show that controlling the RH levels during the heating and the cooling processes (winter and summer conditions respectively) aid the A/C system to

    To evaluate the test-retest reliability of a device that measures urinary sensation during cystometry, and to use that device to determine whether treatment of overactive bladder syndrome (OAB) with solifenacin is associated with a change in urinary sensation. Overall 15 women were recruited for this study, ten women with OAB and urodynamically demonstrated detrusor overactivity and five controls without OAB underwent filling cystometry twice with contemporaneous, continuous recording of urinary sensation. Women with OAB received solifenacin 10 mg daily during the weeks between testing. We compared the areas under the initial and repeat sensation-volume curves. While taking solifenacin, the maximum cystometric capacity increased from 329 ± 168 ml to 464 ± 123 ml (P sensation curve decreased (P sensation during the treatment of OAB with solifenacin. If clinical correlations are confirmed by future study, such urinary sensation measures may prove useful as assessment, treatment predictor, or outcome measures in OAB research and/or clinical care.

    Substance use during adolescence can lead to the development of substance use disorders and other psychosocial problems. These negative outcomes are especially likely for individuals who use substances at earlier ages and those who engage in heavier use during adolescence, behaviors which are both more common among youth at higher risk for developing a substance use disorder, such as those with a family history of substance use disorders (FH+). Factors such as increased sensation seeking and greater exposure to stressors among FH+ youth may influence these associations. Therefore, the aim of this study was to examine the relative and unique contributions of sensation seeking during preadolescence and exposure to stressors during early to mid-adolescence to cumulative substance use by mid-adolescence among FH+ youth. A total of 167 mostly Hispanic FH+ youth (ages 12-15) who were participating in an ongoing longitudinal study were included in these analyses. Participants' data from biennial waves covering approximately 2.5years were used. Self-reported sensation seeking, exposure to stressors, and substance use were compared. Higher sensation seeking during preadolescence and greater exposure to stressors during early to mid-adolescence were both associated with substance use by age 15. These factors differentiated Substance Users from Non-Users, and also related to level of substance use. Elevated sensation seeking and exposure to stressors are both associated with substance use by age 15 among high-risk youth. Additionally, these factors can distinguish youth who develop heavier substance use during this important developmental period. Copyright © 2017. Published by Elsevier Ltd.

    Urinary urgency is an adverse sensory experience. Confirmation of the multidimensional nature of other adverse sensory experiences such as pain and dyspnea has improved the understanding of neurophysiological and perceptual mechanisms leading to innovations in assessment and treatment. It has been suggested that the sensation of urgency may include multiple dimensions such as intensity, suddenness and unpleasantness. In this systematic review we determine which dimensions of sensation have been assessed by instruments used to measure urinary urgency. A systematic search was undertaken of MEDLINE, Embase, AMED, CINAHL, Ageline, Web of Science, InformIT Health and Scopus databases to identify studies that included assessments of urinary urge or urgency. Articles were included in the analysis if they were primary studies that described the method used to measure urge/urgency in adults and published in English in peer reviewed publications since January 1, 2000. Articles were excluded from study if urgency was measured only in conjunction with other symptoms (eg frequency or incontinence) or if there was no English version of the instrument. Secondary analyses and systematic reviews were retained to hand search references for additional primary studies. Data were extracted for the instruments used to measure urge/urgency. For each instrument the items specific to urinary urgency were reviewed using a prospectively developed categorization process for the sensory dimension and the measurement metric. Items used to assess urinary urgency were collated in a matrix (sensory dimensions vs assessment metric). The most frequently used dimensions, metrics and combinations were descriptively analyzed. After removal of duplicate articles 1,048 full text articles were screened and 411 were excluded, leaving 637 eligible articles from which data were extracted. A total of 216 instruments were identified which were 1 of 6 types, namely 1) wider symptom questionnaires, 2) urgency

    Full Text Available This paper examines the rise of an asylum seeker and refugee advocacy movement in Australia in recent years. It situates this phenomenon within Alberto Melucci's understanding of social movements as variable and diffuse forms of social action involved in challenging the logic of a system. Following this theoretical framework, it explores the empirical features of this particular collective action, as well as the struggle to redefine the nature of the relationship between citizens of a sovereign state and 'the other' in the personage of asylum seekers and refugees.

    Full Text Available Autochthon Europeans reacted inconsistently to rising numbers of asylum applications in 2015 and 2016. While some of them welcomed asylum seekers enthusiastically, others reacted with hostility. The objective of this study was to test a predictive model of these individual differences by Structural Equation Modeling (SEM. Both, in a German-speaking (N = 349 Austrians and Germans and in a Slovak (N = 307 adult sample, the perception of "cultural threat" was a strong predictor of attitudes towards asylum seekers, whereas perceived "economic threat" and "modern racism" did not explain additional proportions of the variance.

    The discovery of cortical networks that participate in pain processing has led to the common generalization that blood oxygen level-dependent (BOLD) responses in these areas indicate the processing of pain. Physical stimuli have fundamental properties that elicit sensations distinguishable from pain, such as heat. We hypothesized that pain intensity coding may reflect the intensity coding of heat sensation during the presentation of thermal stimuli during fMRI. Six 3T fMRI heat scans were collected for 16 healthy subjects, corresponding to perceptual levels of "low innocuous heat," "moderate innocuous heat," "high innocuous heat," "low painful heat," "moderate painful heat," and "high painful heat" delivered by a contact thermode to the face. Subjects rated pain and heat intensity separately after each scan. A general linear model analysis detected different patterns of brain activation for the different phases of the biphasic response to heat. During high painful heat, the early phase was associated with significant anterior insula and anterior cingulate cortex activation. Persistent responses were detected in the right dorsolateral prefrontal cortex and inferior parietal lobule. Only the late phase showed significant correlations with perceptual ratings. Significant heat intensity correlated activation was identified in contralateral primary and secondary somatosensory cortices, motor cortex, and superior temporal lobe. These areas were significantly more related to heat ratings than pain. These results indicate that heat intensity is encoded by the somatosensory cortices, and that pain evaluation may either arise from multimodal evaluative processes, or is a distributed process.

    To explore preimmigration experiences of violence and postimmigration health status in male-to-female transgender individuals (n = 45) from Mexico applying for asylum in the United States. We used a document review process to examine asylum declarations and psychological evaluations of transgender Mexican asylum seekers in the United States from 2012. We coded documents in 2013 and 2014 using NVivo, a multidisciplinary team reviewed them, and then we analyzed them for themes. Mexican transgender asylum applicants experienced pervasive verbal, physical, and sexual abuse from multiple sources, including family, school, community, and police. Applicants also experienced discrimination in school and in the workplace. Applicants immigrated to the United States to escape persistent assaults and threats to their life. Applicants suffered health and psychological effects from their experiences in Mexico that affected opportunities in the United States for employment, education, and social inclusion. Additional social protections for transgender individuals and antidiscrimination measures in Mexican schools and workplaces are warranted as are increased mental health assessment and treatment, job training, and education services for asylum seekers in the United States.

  3. The moderating role of socially desirable responding in implicit-explicit attitudes toward asylum seekers.

    2017-07-04

    Implicit and explicit attitudes correlate under certain conditions and researchers are interested in the moderating factors of this relationship. This paper explored the role of socially desirable responding in this relationship by testing the hypothesis that impression management (IM; i.e., deliberate response modification) and self-deceptive enhancement (SDE; i.e., positive self-bias) play moderating roles in the relationship of implicit-explicit attitudes toward asylum seekers in Australia. Seventy-four students responded to a battery of measures and the results revealed that IM (but not SDE) moderated this relationship to the extent that higher IM scores weakened the correspondence between implicit and explicit attitude scores. This suggests that attitudes toward asylum seekers might be susceptible to socially desirable response tendencies and in combination with the finding that IM was negatively related to explicit attitudes, it is argued that self-presentation concerns result in the deliberate attenuation of reported negative explicit attitudes. © 2017 International Union of Psychological Science.

    The impact of industrialised host nations' deterrent immigration policies on the mental health of forced migrants has not been well characterised. The present study investigated the impact of Australia's refugee determination process (RDP) on psychiatric morbidity in community-based asylum-seekers (AS) and refugees. Psychiatric morbidity was predicted to be greater in AS than refugees, and to persist or increase as a function of time in the RDP. The effect on mental health of demographic and socio-political factors such as health cover and work rights were also investigated. Psychiatric morbidity was measured prospectively on five mental health indices at baseline (T1, n=131) and an average of 15.7 months later (T2, n=56). Psychiatric morbidity in AS significantly decreased between time points such that it was no longer greater than that of refugees at T2. Caseness of PTSD and demoralisation reduced in AS who gained protection; however, those who maintained asylum-seeker status at T2 also had a significant reduction in PTS and depression symptom severity. Reduced PTS and demoralisation symptoms were associated with securing work rights and health cover. Living in the community with work rights and access to health cover significantly improves psychiatric symptoms in forced migrants irrespective of their protection status.

    Full Text Available Background: Current knowledge is limited regarding patient characteristics related to treatment outcome of posttraumatic stress disorders (PTSD in refugees and asylum seekers. Objective: Gender, torture status, offender status, level of anger, and level of depression were investigated for possible effects on the treatment outcome. Method: Patient characteristics were explored in 54 refugees and asylum seekers who had completed a treatment program for PTSD. Non-responders (10, those who had the same or higher levels of symptom severity after treatment, were compared with responders, those who had lower symptom severity after treatment (44. Symptom severity was measured by Clinician-Administered PTSD Scale. The non-responders and responders constituted the dichotomous, dependent variable. The independent variables were gender, torture status, offender status, level of anger, and level of depression. T-tests and Exact Unconditional Homogeneity/Independence Tests for 2X2 Tables were used to study the relationship to treatment outcome. Results: Being male and reporting to have been a violent offender were significantly more frequent characteristics among the non-responders compared to the responders. The levels of pretreatment anger, depression and torture status did not affect the treatment outcome. Conclusions: The study adds support to findings that females benefit more from treatment of PTSD than males and that violent offenders are difficult to treat within the standard treatment programs.

    Highlights: • This paper proposes a new method to optimize a Switched Reluctance Motor (SRM). • A combination of SOA and GA with Finite Element Method (FEM) analysis is employed to solve the SRM design optimization. • The results show that optimized SRM obtains higher average torque and higher efficiency. - Abstract: In this paper, performance optimization of Switched Reluctance Motor (SRM) was determined using Seeker Optimization Algorithm (SOA). The most efficient aim of the algorithm was found for maximum torque value at a minimum mass of the entire construction, following changing the geometric parameters. The optimization process was carried out using a combination of Seeker Optimization Algorithm and Finite Element Method (FEM). Fitness value was calculated by FEM analysis using COMSOL3.4, and the SOA was realized by MATLAB. The proposed method has been applied for a case study and it has been also compared with Genetic Algorithm (GA). The results show that the optimized motor using SOA had higher torque value and efficiency with lower mass and torque ripple, exhibiting the validity of this methodology for SRM design

    Decision Support for the Therapy Planning for Young Refugees and Asylum-Seekers with Posttraumatic Disorders Due to the Convention on the Rights of the Child and § 6 of the Asylum Seekers' Benefit Act, there are legal and ethical obligations for the care of minor refugees suffering from trauma-related disorders. In Germany, psychotherapeutic care of adolescent refugees is provided by specialized treatment centers and Child and Adolescent psychiatries with specialized consultation-hours for refugees. Treatment of minor refugees is impeded by various legal and organizational barriers. Many therapists have reservations and uncertainties regarding an appropriate therapy for refugees due to a lack of experience. This means that only a fraction of the young refugees with trauma-related disorders find an ambulatory therapist. In a review of international literature, empirical findings on (interpreter-aided) diagnostics and therapy of young refugees were presented. Practical experiences on therapeutic work with traumatized young refugees were summarized in a decision tree for therapy planning in the ambulatory setting. The decision tree was developed to support therapists in private practices by structuring the therapy process.

    Full Text Available The influx of asylum-seekers and refugees from across Africa into democratic South Africa has increased significantly. The aim of this paper is to determine the factors that influences the expect well-being of this unique group. Expected well-being is an important determinant of both the decision to migrate and the choice of a country of destination. Knowledge about this determinant therefore informs refugee policies. The results show that only a few of the factors found in the literature explaining the expected well-being of voluntary migrants also explain the expected well-being of forced migrants. However, a number of factors found in the literature that explain the subjective well-being and well-being in general of refugees and asylum-seekers also went towards explaining the expected well-being of this group. These factors include: government assistance, culture, the time spent in South Africa, economic factors, crime, refugee status, reasons for leaving the home countries and the number of people staying in a house in the receiving country. The findings of this study emphasise the differences between forced and voluntary migrants and highlight the factors that influence the expected well-being of forced migrants. These in turn shed light on migration decisions and the choice of destination countries.

    Approximately 1500 to 1800 applications for refugee status are made to the New Zealand Immigration Service each year. Approximately one third of these asylum seekers receive health screening from Auckland Public Health. We report here key findings from this screening programme for the period 1999 to 2000. The files of patients attending the Auckland Public Health Protection Asylum Seekers Screening Clinic at Green Lane Hospital were reviewed. Data on demographics, medical examination, diagnostic testing and referrals were analysed. Nine hundred people, mainly from Middle Eastern countries, received screening. Important findings were: symptoms of psychological illness (38.4%); Mantoux skin test positivity ( 36.4%); active tuberculosis (0.6%); TB infection requiring chemoprophylaxis (18%) or chest X-ray monitoring (15%); gut parasite infection; carrier state for alpha and beta thalassaemia and the heterozygous states for HbS and HbE; incomplete immunisation; and the need for referral to a secondary care service (32.6%). Immigrant communities in New Zealand have special healthcare needs, as well as experiencing language barriers, cultural differences and economic difficulties. Healthcare providers should be alert to these needs. Appropriate resources are required to address these issues in a timely fashion.

Hence job seekers are also get benefited with the internet era and start searching the jobs on internet. This study examined the relationship between the recruitment sources, job seekers’ perception and intention to pursue the job. Data was collected from 257 respondents and analysed in relation with the research objectives. The findings of the study showed that internet is the most preferred source to search the job among other recruitment sources. Furthermore, it is also suggested that the effectiveness of e-recruitment depends upon the placement of advertisement and salary is the most influential motivator to find interest in the job applied. Lastly, statistics of the study found that the recruitment sources and applicant’s perceptions of job significantly influence the intention to pursue the position applied by the job seeker.

  11. Sensation seeking related to varied definition of risk

    1998-01-01

    This pilot study is based on the assumption that the normal use of the word risk varies across subjects. It has been shown in previous risk perception studies that some people report their definition or normal use of the concept of risk as e.g. mainly probability, a combination of probability and consequences, mainly consequences, or due to the nature of the event (Drottz-Sjoeberg, 1991). Another field of research has developed measures for personality traits, i.e. facets of Sensation Seeking; Disinhibition, Thrill and Adventure Seeking, Experience Seeking, and Boredom Susceptibility (Zuckerman, 1994). The design of the present study involved three independent groups of first year psychology students (N=93). They were presented with one of three response formats regarding their normal use of the word risk, i.e. an open-ended format, separate ratings of four items suggesting a definition of risk on five-point scales, and one single five-point scale with the extremes labelled probability and consequences, and with their combination as the scale mid-point. The results showed, e.g. that the typical open-ended response to the personal definition of risk was 'danger', but among the responses were also 'chance', and 'outcome'. Another finding was that people who defined risk as 'outcome' and 'chance', using the open-ended format tended to score higher on the total Sensation Seeking Scale than those who defined risk as 'danger'. In addition, subjects who defined risk as the 'combination' of probability and consequences, using other response formats, also tended to score higher on the total Sensation Seeking Scale (SSS), especially as compared to those defining risk as the 'probability' of an event.

    Full Text Available The lack of correlation between available knowledge and the current approach to Somatoform Disorders is highlighted.. Methods: the study, via the analysis of an unusual clinical case of an anomalous sensation of cold, examines various hypotheses on the physiopathology of somatization. Conclusions: a conceptualization would focus attention on the level of patients’ preoccupation with their symptoms, on the anomalies of the variations of perceptions and on patients’ hyperarousal. It could lead to a more harmonious position in psychiatry, between anthropologically-based understanding and interpretation of psychophysical information.

    Substance use disorder is a serious health problem that tends to manifest in late adolescence. Attempting to influence targetable risk and protective factors holds promise for prevention and treatment. Survey data from 1,253 college students (48.5% male, 26.9% non-White) were used to investigate the independent and combined effects of two prominent factors, sensation seeking and parental monitoring, on the probability of alcohol and/or cannabis dependence during the first year of college. In multivariate analyses that controlled for high school use, gender, race, mother’s education, and importance of religion, retrospective reports by the student of parental behavior during the last year of high school indicated that higher levels of parental monitoring had a direct effect on reducing risk for alcohol dependence during the first year of college, but not on cannabis dependence. High levels of sensation seeking were associated with increased risk for both alcohol and cannabis dependence. No interaction effects were found. The results extend prior findings by highlighting influences of pre-college parental monitoring and sensation seeking on the probability of alcohol and/or cannabis dependence during the first year of college. The findings also suggest that these two factors are useful in identifying college students at high risk for alcohol and/or cannabis dependence. PMID:23017733

    Young men who have sex with men (YMSM) have become high risk groups for HIV infection in China. Recent researches suggest that sexual sensation seeking is significantly associated with AIDS-related knowledge, attitudes and behaviors, but the relationship is not clear in the field of YMSM in China. The present study aimed to evaluate the relationship between sexual sensation seeking and AIDS-related knowledge, attitudes, and behaviors among YMSM in China. A cross-sectional study was conducted in Wuhan, China from May to November 2013. 403 YMSM were recruited and 373 of them completed the questionnaire. Regression analyses indicated that YMSM with high sexual sensation seeking score are more likely to have low awareness of knowledge and negative attitude about condom use, as well as more risky sexual behaviors.

    There is growing evidence of the impact of post-migration factors on the mental health of refugees. To date, few UK studies have been conducted. The study investigated the relationship between trauma, post-migration problems, social support and the mental health of refugees and asylum seekers. Refugees and asylum seekers (n = 47) were recruited mainly from clinical settings. Self-report measures of post-migration problems, mental health problems and social support were completed in an interview. Bivariate associations were identified between increased symptoms and number of traumas, adaptation difficulties, loss of culture and support and confidant support. In multivariate analyses post-migration problems were significantly associated with post-traumatic stress disorder symptoms and emotional distress. There was no significant association of symptoms and number of traumas or social support. The results suggest that clinical services should provide holistic interventions within a phased approach when working with refugees and asylum seekers. At a policy level, the results suggest the need for asylum policies that reduce post-migration problems and provide support for refugees and asylum seekers.

    National statistics have shown that only about 40% of asylum seekers actually attend the optional health assessment offered upon their arrival in Sweden, but the reasons for this have not been fully explored. Health assessments for newly arrived asylum seekers have become a regular practice in most EU countries, but what is performed, how it is organized and whether it is mandatory or not varies between countries. The aim of the study was to explore and improve our understanding of how former asylum seekers from Eritrea perceived and experienced the health assessment during their asylum-seeking process. We used a qualitative research approach guided by grounded theory. Semi-structured interviews were conducted with 11 former asylum seekers from Eritrea. Data were analysed based on constant comparative analysis. The asylum seekers expressed feelings of ambiguity and mistrust and felt that they were seen only as objects by the Swedish healthcare system during their asylum-seeking process. Poor communication and inability to overcome language and cultural barriers seemed to be the most important findings in the narratives. The core category was defined as 'A state of limbo - in transition between two contexts'. There are reasons to believe that these issues with communication negatively affected both the quality of the health assessment and the number of asylum seekers attending the health assessment. Improved communication by the authorities towards the asylum seekers is, therefore, of vital importance. © 2015 the Nordic Societies of Public Health.

The purpose of this research is to join the UNESCO initiative by granting quality education, boosted by technology (Rose, 2013. Specifically, the objective is to analyze the impact of using a tutorial video on academic achievement, based on Gestalt psychology stimulating the sensation and perception cognitive capabilities. Using a 50 student sample was used, which was divided into two groups (experimental and control we test whether students that use a tutorial video based on sensation and perception increase their attention and interest to increase academic achievement. The experimental group was a virtual class with tutorial videos on the use of slopes, explanation of the equation, and a virtual graph generator. Both groups were a survey and an exam. The results show that a high impact on the grades and on the perception of knowledge in the experimental group; the average academic achievement of the experimental group was 9.31, against 2 in the control group. Thus, we conclude that the tutorial video presented stimulates cognitive capabilities and improves academic achievement with a 7.3 impact per additional unit of tutorial video, presented as reinforcement of the class.

    2008-11-01

    The association between sensation seeking and visual selective attention was examined in 31 adults with the Human Immunodeficiency Virus (HIV). Sensation seeking was measured with Zuckerman's Sensation Seeking Scale Form V (SSS-V). Selective attention was assessed with a perceptual span task, where a target letter-character must be identified in a quickly presented array of nontarget letter-characters. As predicted, sensation seeking was strongly associated (R(2) = .229) with perceptual span performance in the array size 12 condition, where selective attention demands were greatest, but not in the easier conditions. The Disinhibition, Boredom Susceptibility, and Experience Seeking subscales of the SSS-V were associated with span performance. It is argued that personality factors such as sensation seeking may play a significant role in selective attention and related cognitive abilities in HIV positive adults. Furthermore, sensation seeking differences might explain certain inconsistencies in the HIV neuropsychology literature.

  7. Effect of wind speed on human thermal sensation and thermal comfort

    2018-06-01

    In this experiment, a method of questionnaire survey was adopted. By changing the air flow rate under the indoor and outdoor natural conditions, the subjective Thermal Sensation Vote (TSV) and the Thermal Comfort Vote (TCV) were recorded. The draft sensation can reduce the thermal sensation, but the draft sensation can cause discomfort, and the thermal comfort in a windy environment is lower than in a windless environment. When the temperature rises or the level of human metabolism increases, the person feels heat, the demand for draft sensation increases, and the uncomfortable feeling caused by the draft sensation may be reduced. Increasing the air flow within a certain range can be used to compensate for the increase in temperature.

  8. Non-clinicians’ judgments about asylum seekers’ mental health: how do legal representatives of asylum seekers decide when to request medico-legal reports?

    Directory of Open Access Journals (Sweden)

    Lucy Wilson-Shaw

    2012-10-01

    Full Text Available Background : Procedures for determining refugee status across Europe are being speeded up, despite the high prevalence of mental health difficulties among asylum seekers. An assurance given is that ‘‘vulnerable applicants’’ will be identified and excluded from accelerated procedures. Although experts have recommended assessments to be undertaken by experienced clinicians, this is unlikely to happen for political and financial reasons. Understanding how non-clinically qualified personnel perform assessments of mental health issues is timely and crucial. Misrecognition of refugees due to the inappropriate use of accelerated procedures involves the risk of returning the very people who have the right to protection from further persecution. Objective : To examine the decision making of immigration lawyers, who are an example of a group of nonclinicians who decide when and whether to refer asylum-seekers for psychiatric assessment. Method : Semi-structured interviews were conducted with 12 legal representatives working with people seeking refugee or human rights protection in the United Kingdom. The resultant material was analysed using Framework Analysis. Results : Themes clustered around the legal case, the client, the representative and the systems, all with sub-themes. A mapping exercise integrated these themes to show how representatives brought together questions of (1 evidential reasons for a report, influenced by their legal, psychological and case law knowledge, and (2 perceived evidence of mental distress, influenced by professional and personal experiences and expectations. Conclusions : The legal representatives interviewed were well-informed and trained in psychological issues as well as clearly dedicated to their clients. This helped them to attempt quasi-diagnoses of common mental health problems. They nonetheless demonstrated stereotypical understanding of post-traumatic stress disorder and other possible diagnoses and the

    To characterize the effect of sacral neuromodulation (SNM) on urethral neuromuscular function. Following IRB approval, women with refractory overactive bladder (OAB) underwent standardized urethral testing prior to and after Stage 1 SNM implantation. Periurethral sensation was measured using current perception thresholds (CPT). Striated urethral sphincter activity was quantified using concentric needle electromyography (CNE) and Multi-Motor Unit Action Potential (MUP) analysis software. Nonparametric analyses were used to characterize pre/post changes with intervention. Baseline CPT and CNE findings were compared between SNM responders and non-responders. Twenty-seven women were enrolled in this pilot study with a mean age of 61 ± 13 years. Twenty of 26 women (76.9%) responded to SNM and went to Stage 2 permanent implantation. Four (14.8%) withdrew after Stage 1 implantation; three of the four withdrawals had not had therapeutic responses to SNM. CPT and CNE parameters did not significantly differ from baseline 2 weeks after SNM. Pre-SNM urethral sensation was not significantly different between responders and non-responders. However, responders had larger amplitude, longer duration and more turns and phases at baseline approaching significance, reflecting more successful urethral reinnervation, than non-responders. SNM does not alter urethral neuromuscular function 2 weeks post Stage 1 implantation. Copyright © 2012 Wiley Periodicals, Inc.

    The reproducibility of three questions, related to fullness, satiety and desire to eat, rated on an unmarked triangle was verified. In four sessions 12 volunteers ate pasta with tomato sauce (520 kcal) and were asked to rate the sensations felt. There was no difference in rating scores of the replications so the proposed questionnaire provides a stable measure of sensations related to satiety. Subsequently three satiety conditions were studied. Two foods, one rich in carbohydrate, pasta (baked macaroni) and the other in protein, polpette (meatballs), were used as loads at two calorie levels and as preload before an "ad libitum" meal. All the three questions proved useful in discriminating between the different satiety conditions. The food intake underlines the specificity of satiety: subjects, after eating a preload which previously had satiated them, ate other foods in different amounts depending on the kind of preload eaten. Food intake was significantly higher after the pasta preload, furthermore "fullness" and "satiety" ratings were significantly highest after the meatball preload, suggesting that in our experimental conditions, meatballs were more satiating than pasta. In conclusion, this study highlights the validity of using several quite different questions to study hunger and satiety, together with the actual food intake.

    Infrared guided missile seekers utilizing pulse width modulation in target tracking is one of the threats against air platforms. To be able to achieve a "soft-kill" protection of own platform against these type of threats, one needs to examine carefully the seeker operating principle with its special electronic counter-counter measure (ECCM) capability. One of the cost-effective ways of soft kill protection is to use flare decoys in accordance with an optimized dispensing program. Such an optimization requires a good understanding of the threat seeker, capabilities of the air platform and engagement scenario information between them. Modeling and simulation is very powerful tool to achieve a valuable insight and understand the underlying phenomenology. A careful interpretation of simulation results is crucial to infer valuable conclusions from the data. In such an interpretation there are lots of factors (features) which affect the results. Therefore, powerful statistical tools and pattern recognition algorithms are of special interest in the analysis. In this paper, we show how self-organizing maps (SOMs), which is one of those powerful tools, can be used in analyzing the effectiveness of various flare dispensing programs against a PWM seeker. We perform several Monte Carlo runs for a typical engagement scenario in a MATLAB-based simulation environment. In each run, we randomly change the flare dispending program and obtain corresponding class: "successful" or "unsuccessful", depending on whether the corresponding flare dispensing program deceives the seeker or not, respectively. Then, in the analysis phase, we use SOMs to interpret and visualize the results.

    Application of camphor to the skin has been empirically thought to improve blood circulation. However, camphor's effects on blood circulation to the skin and on thermal sensation have not been well elucidated. In this study, we examined its effects on the quality of sensation as well as on skin and muscle blood flow in human. Nine adults (average age 37±9.4 years) participated in the study. Petroleum jelly containing 5%, 10%, 20% camphor, or 2% menthol was separately applied to the skin on the medial side of one forearm of each subject. Just after the application, camphor at each concentration induced a cold sensation in a dose-dependent manner. Within 10 min, each subject reported that the cold sensation had faded, after which it was replaced by a warm sensation. As reported previously, a cold sensation was induced by application of 2% menthol, but the subjects did not adapt to that sensation. In addition, menthol did not induce a warm sensation at all. Application of menthol has been shown to increase blood flow in the skin. Finally, we measured blood flow in skin and muscle after the application of camphor or menthol. Application of camphor or menthol separately induced increases in local blood flow in the skin and muscle. The present results indicate that camphor induces both cold and warm sensations and improves blood circulation.

    This paper presents the development of a myoelectric prosthetic hand based on a 3D printed model. A myoelectric control strategy based on artificial neural networks is implemented on a microcontroller for online position estimation. Position estimation performance achieves a correlation index of 0.78. Also a study involving transcutaneous electrical stimulation was performed to provide tactile feedback. A series of stimulations with controlled parameters were tested on five able-body subjects. A single channel stimulator was used, positioning the electrodes 8 cm on the wrist over the ulnar and median nerve. Controlling stimulation parameters such as intensity, frequency and pulse width, the subjects were capable of distinguishing different sensations over the palm of the hand. Three main sensations where achieved: tickling, pressure and pain. Tickling and pressure were discretized into low, moderate and high according to the magnitude of the feeling. The parameters at which each sensation was obtained are further discussed in this paper.

    Little is known about the experiences of displaced individuals en route to destination countries. We investigated the reported prevalence of exposure to traumatic experiences during migration among a consecutive sample of adult asylum seekers (n = 895 Eritrean, n = 149 Sudanese) who sought health services in the Physicians for Human Rights Open-Clinic in Israel. Percentage of Eritrean and Sudanese men and women who reported witnessing violence (Eritrea: men: 41.3 %, women: 29.3 %; Sudan: men: 16.8 %, women: 22.2 %) and/or being a victim of violence (Eritrea: men: 56.0 %, Women: 34.9 %; Sudan: men: 51.9 % women: 44.4 %) during migration varied by gender and country of origin. Findings highlight the need for a well-coordinated international cooperation to document and prevent these transgressions.

    The treatment of hunger strikers is always contentious, chaotic and complex. The management is particularly difficult for health professionals as it raises unprecedented clinical, ethical, moral, humanitarian, and legal questions. There are never any easy answers. The current situation of prisoners from the Iraq and Afghanistan Wars currently at the Guantanamo Bay Detention Center in Cuba demands unprecedented transparency, accountability and multilevel coordination to ensure that the rights of the strikers are properly met. There are scant references available in the scientific literature on the emergency management of these tragedies. This historical perspective documents the complex issues faced by emergency physicians in Hong Kong surrounding refugee camp asylum seekers from Vietnam in 1994 and is offered as a useful adjunct in understanding the complex issues faced by emergency health providers and managers.

    Full Text Available Unaccompanied minor asylum seekers are vulnerable and thus, provided special international law protections. However, in reality, they are being mistreated as illegal immigrants and on thereceiving end of ethnic violence, discrimination, restrictions in enjoyment of their rights duly recognised by international human rights law. This article identifies legislative, policy and supportmechanisms which encompass the minimum UMAS guardianship standards at international law and which are evidence-based from best practice models for the provision of guardians for UMASinternationally. It presents situation of UMAS in relation to human rights violations with emphasis on the legal framework and practices in Australia and five ASEAN State Members. This article also highlights the various stands taken by various countries providing better legal framework and practices regarding the terms for protection and enforcement of human rights for UMAS. Finally, this article provides recommendations for Australia and ASEAN Member States to adopt in order to realise the international human rights of UMAS with respect to guardianship.

    Inducing emotional reactions toward social groups can influence individuals' political tolerance. This study examines the influence of incidental fear and happiness on adolescents' tolerant attitudes and feelings toward young Muslim asylum seekers. In our experiment, 219 16- to 21-year-olds completed measures of prejudicial attitudes. After being induced to feel happiness, fear, or no emotion (control), participants reported their tolerant attitudes and feelings toward asylum-seeking young people. Participants assigned to the happiness condition demonstrated more tolerant attitudes toward asylum-seeking young people than did those assigned to the fear or control conditions. Participants in the control condition did not differ from participants in the fear condition. The participants in the happiness condition also had more positive feelings toward asylum-seeking young people than did participants in the control condition. The findings suggest that one way to increase positive attitudes toward asylum-seeking young people is to improve general emotional state.

    Improving the oral health of refugees and asylum seekers is a global priority, yet little is known about the overall burden of oral diseases and their causes for this population. To synthesize available evidence on the oral health of, and access to oral health care by this population. Using a scoping review methodology, we retrieved 3321 records from eight databases and grey literature; 44 publications met the following inclusion criteria: empirical research focused on refugees and/or asylum seekers' oral health, published between 1990 and 2014 in English, French, Italian, Portuguese, or Spanish. Analysis included descriptive and thematic analysis, as well as critical appraisal using the Critical Appraisal Skills Programme (CASP) criteria for quantitative and qualitative studies. The majority of publications (86 %) were from industrialized countries, while the majority of refugees are resettled in developing countries. The most common study designs were quantitative (75 %). Overall, the majority of studies (76 %) were of good quality. Studies mainly explored oral health status, knowledge and practices; a minority (9 %) included interventions. The refugee populations in the studies showed higher burden of oral diseases and limited access to oral health care compared to even the least privileged populations in the host countries. Minimal strategies to improve oral health have been implemented; however, some have impressive outcomes. Oral health disparities for this population remain a major concern. More research is needed on refugees in developing countries, refugees residing in refugee camps, and interventions to bridge oral health disparities. This review has utility for policymakers, practitioners, researchers, and other stakeholders working to improve the oral health of this population.

    Public health professionals have a responsibility to protect and promote the right to health amongst populations, especially vulnerable and disenfranchised groups, such as people seeking asylum and whose health care is frequently compromised. As at 31 March 2016, there was a total of 3707 people (including 384 children) in immigration detention facilities or community detention in Australia, with 431 of them detained for more than 2 years. The Public Health Association of Australia and the Australian Medical Association assert that people seeking asylum in Australia have a right to health in the same way as Australian citizens, and they denounce detention of such people in government facilities for prolonged and indeterminate periods of time. The position of these two professional organisations is consistent with the compelling body of evidence demonstrating the negative impact detention has on health. Yet in recent years, both the Labour and Liberal parties-when at the helm of Australia's Federal Government-have implemented a suite of regressive policies toward individuals seeking asylum. This has involved enforced legal restrictions on dissenting voices of those working with these populations, including health professionals. This paper outlines Australia's contemporary offshore immigration detention policy and practices. It summarises evidence on asylum seeker health in detention centres and describes the government's practice of purposeful silencing of health professionals. The authors examine how Australia's treatment of asylum seekers violates their health rights. Based on these analyses, the authors call for concrete action to translate the overwhelming body of evidence on the deleterious impacts of immigration detention into ethical policy and pragmatic interventions. To this end, they provide four recommendations for action.

    One of the key aspects for the design of a next generation weapon system is the need to operate in cluttered and complex urban environments. Simulation systems rely on accurate representation of these environments and require automated software tools to construct the underlying 3D geometry and associated spectral and material properties that are then formatted for various objective seeker simulation systems. Under an Air Force Small Business Innovative Research (SBIR) contract, we have developed an automated process to generate 3D urban environments with user defined properties. These environments can be composed from a wide variety of source materials, including vector source data, pre-existing 3D models, and digital elevation models, and rapidly organized into a geo-specific visual simulation database. This intermediate representation can be easily inspected in the visible spectrum for content and organization and interactively queried for accuracy. Once the database contains the required contents, it can then be exported into specific synthetic scene generation runtime formats, preserving the relationship between geometry and material properties. To date an exporter for the Irma simulation system developed and maintained by AFRL/Eglin has been created and a second exporter to Real Time Composite Hardbody and Missile Plume (CHAMP) simulation system for real-time use is currently being developed. This process supports significantly more complex target environments than previous approaches to database generation. In this paper we describe the capabilities for content creation for advanced seeker processing algorithms simulation and sensor stimulation, including the overall database compilation process and sample databases produced and exported for the Irma runtime system. We also discuss the addition of object dynamics and viewer dynamics within the visual simulation into the Irma runtime environment.

    Full Text Available Background: Asylum interviews within the asylum procedure are associated with psychological stress for traumatized asylum seekers. This study investigates the impact of asylum interviews on the mental health in a sample of 40 traumatized asylum seekers. The comparison group consisted of refugees (N=10 that had not been invited to an asylum interview. Additionally, the moderating effects of trial-related variables such as perceived justice of the trial, stress of giving testimony, and stress of waiting for the asylum interview were examined. Method: Participants were assessed on average 10 days before (t1 and 16 days after (t2 the asylum interview. Chi-square tests for dichotomous and categorical variables were used to compare the descriptive statistics of the two groups. To investigate symptom changes from t1 to t2, paired t-tests were calculated. The magnitude of effects was measured by Cohen's effect size d within groups. Hierarchical regression analyses were conducted for demographic and trial variables predicting posttraumatic intrusions, avoidance, and hyperarousal. Results: Data showed a significant increase in posttraumatic intrusions and a significant decrease in posttraumatic avoidance and hyperarousal symptoms from t1 to t2. No significant symptom changes in the posttraumatic stress disorder subscales were found in the comparison group. The results of hierarchical regression analyses revealed perceived justice of the interview to predict the increase of intrusions and the number of experienced traumata and testimony stress to predict posttraumatic avoidance. Conclusions: The present findings underline the stressful impact of asylum interviews on traumatized refugees. They indicate that the asylum interview might decrease posttraumatic avoidance and trigger posttraumatic intrusions, thus highlight the importance of ensuring that the already vulnerable group of traumatized refugees needs to be treated with empathy during their asylum

  4. The neural mechanisms of re-experiencing mental fatigue sensation: a magnetoencephalography study.

    Full Text Available There have been several studies which have tried to clarify the neural mechanisms of fatigue sensation; however fatigue sensation has multiple aspects. We hypothesized that past experience related to fatigue sensation is an important factor which contributes to future formation of fatigue sensation through the transfer to memories that are located within specific brain structures. Therefore, we aimed to investigate the neural mechanisms of fatigue sensation related to memory. In the present study, we investigated the neural activity caused by re-experiencing the fatigue sensation that had been experienced during a fatigue-inducing session. Thirteen healthy volunteers participated in fatigue and non-fatigue experiments in a crossover fashion. In the fatigue experiment, they performed a 2-back test session for 40 min to induce fatigue sensation, a rest session for 15 min to recover from fatigue, and a magnetoencephalography (MEG session in which they were asked to re-experience the state of their body with fatigue that they had experienced in the 2-back test session. In the non-fatigue experiment, the participants performed a free session for 15 min, a rest session for 15 min, and an MEG session in which they were asked to re-experience the state of their body without fatigue that they had experienced in the free session. Spatial filtering analyses of oscillatory brain activity showed that the delta band power in the left Brodmann's area (BA 39, alpha band power in the right pulvinar nucleus and the left BA 40, and beta band power in the left BA 40 were lower when they re-experienced the fatigue sensation than when they re-experienced the fatigue-free sensation, indicating that these brain regions are related to re-experiencing the fatigue sensation. Our findings may help clarify the neural mechanisms underlying fatigue sensation.

Pain ratings from these procedures were also compared with common psychological measures previously shown to be related to experimental pain responses and consistent with fear-avoidance models of pain. Results indicated that supra-threshold stimulus response scaling, temporal summation, and after-sensation, were significantly related to each other. The site of stimulation was also an important factor, with the trunk site showing the highest sensitivity in all three quantitative sensory testing procedures. Supra-threshold response measures were highly related to measures of fear of pain and anxiety sensitivity for all stimulation sites. For temporal summation and after-sensation, only the trunk site was significantly related to anxiety sensitivity, and fear of pain, respectively. Results suggest the importance of considering site of stimulation when designing and comparing studies. Furthermore, psychological influence on quantitative sensory testing is also of importance when designing and comparing studies. Although there was some variation by site of stimulation, fear of pain and anxiety sensitivity had consistent influences on pain ratings.Keywords: experimental pain, temporal summation, after-sensation, fear/avoidance, anxiety

    At its most fundamental level, touch sensation requires the translation of mechanical energy into mechanosensitive ion channel opening, thereby generating electro-chemical signals. Our understanding of this process, especially how the cytoskeleton influences it, remains unknown. Here we demonstrate that mice lacking the α-tubulin acetyltransferase Atat1 in sensory neurons display profound deficits in their ability to detect mechanical stimuli. We show that all cutaneous afferent subtypes, including nociceptors have strongly reduced mechanosensitivity upon Atat1 deletion, and that consequently, mice are largely insensitive to mechanical touch and pain. We establish that this broad loss of mechanosensitivity is dependent upon the acetyltransferase activity of Atat1, which when absent leads to a decrease in cellular elasticity. By mimicking α-tubulin acetylation genetically, we show both cellular rigidity and mechanosensitivity can be restored in Atat1 deficient sensory neurons. Hence, our results indicate that by influencing cellular stiffness, α-tubulin acetylation sets the force required for touch.

    Children with functional constipation often state an inability to sense an urge to defecate and/or inability to feel incontinence. We used colon manometry to assess whether there was a sensory abnormality in patients who denied sensation. A physician observed all of the colon manometries in the preceding 20 years, and included behavioral observations in the procedure reports. We reviewed the charts of these patients. Of 150 subjects with normal manometry and a diagnosis of functional constipation, 56 volunteered that they had no urge to defecate or complained of abdominal pain. For all who denied sensation, the first high-amplitude propagating colonic contraction (HAPC) was associated with retentive posturing and facial grimaces. When queried, all reported they felt nothing. The examiner explained the HAPC was causing pain, and informed the child that the pain would resolve if they defecated. With subsequent HAPCs, every patient acknowledged an urge to defecate and successfully defecated. Most agreed that a similar pain sensation was present daily, but was misinterpreted to be abdominal pain. Colon manometry may be useful not only for objective findings to discriminate neuromuscular disease from functional symptoms but also to understand psychological issues and aid in helping the child and family understand the maladaptive behaviors in functional constipation.

  10. Sensation seeking moderates television's cultivation of alcohol and tobacco beliefs: Evidence from a national study of French adolescents.

    Russell, Cristel Antonia; Russell, Dale W

    2018-05-01

    Television (TV) is a key socialization agent, especially amongst youth. According to cultivation theory, youth heavily exposed to TV content, where positive images of smoking and drinking abound, should hold more positive beliefs concerning drinking and smoking outcomes. This research investigates the role of the sensation-seeking personality trait in moderating this TV cultivation effect. A French national research company contacted its panel members with children aged 13-17. Parents completed a short survey and were asked for consent for their child to participate in a study. The children were then contacted, informed, and asked for assent. Assenters completed a survey that included measures of TV exposure, personality traits, drinking and smoking behaviors, and beliefs about the outcomes associated with drinking and smoking (expectancies). Parental drinking, smoking, and strictness were included as controls. Survey data from 1040 adolescents (54.2% males) and their parents reveal that the relationship between cumulative TV exposure and drinking and smoking behavior, mediated through expectancies, is strongest amongst high sensation seeking adolescents. The moderated mediation analysis shows that sensation seeking trait moderates the relationship between TV exposure and the beliefs adolescents hold about the consequences of alcohol and tobacco use, which themselves are related to greater likelihood to engage in substance use. Key personality traits and TV exposure levels must be accounted for to identify youth at risk of using substances at a time when many lifelong maladaptive behaviors and beliefs form.

    It is important to know how thermal sensation is affected by normal aging under conditions that elevate core body temperature for the prevention of heat-related illness in older people. We assessed whether thermal sensation under conditions of normothermia (NT) and mild hyperthermia (HT) is lowered in older adults. Seventeen younger (23 ±  3 years) and 12 older (71 ±  3 years) healthy men underwent measurements of the cold and warmth detection thresholds ( ± 0.1 °C/s) of their chest and forearm skin, and whole body warmth perception under NT (esophageal temperature, T es, ~36.5 °C) and HT (T es, ~37.3 °C; lower legs immersed in 42 °C water) conditions. Warmth detection threshold at the forearm was increased in older compared with younger participants under both NT (P = 0.006) and HT (P = 0.004) conditions. In contrast, cold detection threshold at the forearm was decreased in older compared with younger participants under NT (P = 0.001) but not HT (P = 0.16). Mild hyperthermia decreased cold detection threshold at forearm in younger participants (P = 0.001) only. There were no effects of age and condition on warmth and cold detection thresholds at chest. Whole body warmth perception increased during HT compared with NT in both groups (both, P perception under NT and HT and skin cold detection thresholds at forearm under NT deteriorated with aging.

    The purpose of this investigation was to develop a non-invasive, objective, and unprompted method to characterize real-time bladder sensation. Volunteers with and without overactive bladder (OAB) were prospectively enrolled in a preliminary accelerated hydration study. Participants drank 2L Gatorade-G2® and recorded real-time sensation (0-100% scale) and standardized verbal sensory thresholds using a novel, touch-screen "sensation meter." 3D bladder ultrasound images were recorded throughout fillings for a subset of participants. Sensation data were recorded for two consecutive complete fill-void cycles. Data from 14 normal and 12 OAB participants were obtained (ICIq-OAB-5a = 0 vs. ≥3). Filling duration decreased in fill2 compared to fill1, but volume did not significantly change. In normals, adjacent verbal sensory thresholds (within fill) showed no overlap, and identical thresholds (between fill) were similar, demonstrating effective differentiation between degrees of %bladder capacity. In OAB, within-fill overlaps and between-fill differences were identified. Real-time %capacity-sensation curves left shifted from fill1 to fill2 in normals, consistent with expected viscoelastic behavior, but unexpectedly right shifted in OAB. 3D ultrasound volume data showed that fill rates started slowly and ramped up with variable end points. This study establishes a non-invasive means to evaluate real-time bladder sensation using a two-fill accelerated hydration protocol and a sensation meter. Verbal thresholds were inconsistent in OAB, and the right shift in OAB %capacity-sensation curve suggests potential biomechanical and/or sensitization changes. This methodology could be used to gain valuable information on different forms of OAB in a completely non-invasive way. © 2016 Wiley Periodicals, Inc.

    Full Text Available Previous research has linked anti-social behavior (ASB to subtypes of empathy and also to sensation seeking, but there is limited research on the relative roles of empathy subtypes and sensation seeking traits in predicting ASB subtypes. The current study therefore investigated the relationship between sensation seeking, the three subtypes of empathy (emotional reactivity, cognitive empathy and social skills and the two subtypes of ASB (physically aggressive and non-aggressive. An online survey consisting of Demographic Variables Questionnaire, Brief Sensation Seeking Scale, Empathy Quotient and the Antisocial Behavior Measure was sent to student volunteers, leading to a total of 537 respondents. Empathy alone accounted for a relatively modest proportion of the total variance in the ASBs, with emotional reactivity being the only significant predictor. Adding sensation seeking to the regression led to a marked improvement in prediction for non-aggressive ASB and a slight but significant improvement for physically aggressive ASB. Sensation seeking, emotional reactivity and social skills (but not cognitive empathy contributed unique variance for both ASB subtypes. The greatest variance for physically aggressive and non-aggressive ASB were accounted for by emotional reactivity and sensation seeking, respectively. The results indicate that both sensation seeking and sub-types of empathy are important in predicting ASBs. This has theoretical implications for different personality models and has practical implications for the development of preventive measures to avoid such behaviors.

    A number of studies have associated impulsivity and sensation seeking with level of substance use and risk for developing a substance use disorder. These relationships may be particularly apparent during adolescence, when developmental changes in impulsivity and sensation seeking occur at the same time as increased opportunities for substance use. To examine this, the current study measured impulsivity and sensation seeking from pre-adolescence to mid-adolescence in a sample of youth, the majority of whom were identified as being at risk for developing a substance use disorder based on their family history of substance use disorders. Youth were separated into those who did (n = 117) and did not (n = 269) initiate substance use by mid-adolescence. Results showed that substance users were more impulsive and more sensation seeking during pre-adolescence, prior to any significant substance use, and that greater sensation seeking in pre-adolescence was related to heavier substance use by mid-adolescence. In addition, developmental trajectories for substance-using youth showed a greater increase in sensation seeking but a more modest decrease in impulsivity from pre-adolescence to mid-adolescence. Taken together, these results indicate that increased impulsivity and sensation seeking is apparent in adolescent substance users as early as pre-adolescence, that the difference between substance users and non-users becomes larger across early adolescence as their developmental trajectories diverge, and that greater sensation seeking in pre-adolescence may predict increased substance use by mid-adolescence.

    Thermal sensation represents the primary stimulus for behavioral and autonomic thermoregulation. We assessed whether the sensation of skin and core temperatures for the driving force of behavioral thermoregulation was modified by postural change from the supine (Sup) to sitting (Sit) during mild hyperthermia. Seventeen healthy young men underwent measurements of noticeable increase and decrease (±0.1 °C/s) of skin temperature (thresholds of warm and cold sensation on the skin, 6.25 cm 2 of area) at the forearm and chest and of the whole-body warm sensation in the Sup and Sit during normothermia (NT; esophageal temperature (T es ), ∼36.6 °C) and mild hyperthermia (HT; T es , ∼37.2 °C; lower legs immersion in 42 °C of water). The threshold for cold sensation on the skin at chest was lower during HT than NT in the Sit (P sensation on the skin at both sites remained unchanged with changes in body posture or temperature. The whole-body warm sensation was higher during HT than NT in both postures and higher in the Sit than Sup during both NT and HT (all, P sensation during mild hyperthermia is modulated by postural change from supine to sitting to sense lesser cold on the skin and more whole-body warmth.

    A recent study showed that fingertip pads’ tactile sensation can improve by applying imperceptible white-noise vibration to the skin at the wrist or dorsum of the hand in stroke patients. This study further examined this behavior by investigating the effect of both imperceptible and perceptible white-noise vibration applied to different locations within the distal upper extremity on the fingertip pads’ tactile sensation in healthy adults. In 12 healthy adults, white-noise vibration was applied to one of four locations (dorsum hand by the second knuckle, thenar and hypothenar areas, and volar wrist) at one of four intensities (zero, 60%, 80%, and 120% of the sensory threshold for each vibration location), while the fingertip sensation, the smallest vibratory signal that could be perceived on the thumb and index fingertip pads, was assessed. Vibration intensities significantly affected the fingertip sensation (P sensation (P sensation (P sensation (P > 0.01), all compared with the zero vibration condition. This effect with vibration intensity conforms to the stochastic resonance behavior. Nonspecificity to the vibration location suggests the white-noise vibration affects higher level neuronal processing for fingertip sensing. Further studies are needed to elucidate the neural pathways for distal upper extremity vibration to impact fingertip pad tactile sensation. PMID:26177959

    Full Text Available Background and aim: Transition of asylum seekers from special-purpose health services to mainstream primary care is both necessary and difficult. This study explores the issues encountered by asylum seekers undergoing this transition in Sydney, Australia. Methods: Qualitative semistructured interviews were conducted with nine asylum seeker patients and nine staff working in the sector. Results: Asylum seekers faced significant challenges in the transition to mainstream primary care. Contributing factors included the complexity of health and immigration systems, the way in which asylum seeker–specific services provide care, lack of understanding and accommodation by mainstream general practioner (GP services, asylum seekers’ own lack of understanding of the health system, mental illness, and social and financial pressures. Conclusions: There is a need for better preparation of asylum seekers for the transition to mainstream primary care. Mainstream GPs and other providers need more education and support so that they can better accommodate the needs of asylum seeker patients. This is an important role for Australia’s refugee health services and Primary Health Networks.

  7. Aggressive behavior: an alternative model of resting heart rate and sensation seeking.

    Wilson, Laura C; Scarpa, Angela

    2014-01-01

    Low resting heart rate is a well-replicated biological correlate of aggression, and sensation seeking is frequently cited as the underlying causal explanation. However, little empirical evidence supports this mediating relationship. Furthermore, the biosocial model of violence and social push theory suggest sensation seeking may moderate the relationship between heart rate and aggression. In a sample of 128 college students (82.0% White; 73.4% female), the current study tested a moderation model as an alternative relationship between resting heart rate and sensation seeking in regard to aggression. Overall, the findings partially supported an interaction effect, whereby the relationship between heart rate and aggression was moderated by sensation seeking. Specifically, the oft-noted relationship between low resting heart rate and increased aggression was found, but only for individuals with low levels of sensation seeking. If replication supports this finding, the results may better inform prevention and intervention work. © 2013 Wiley Periodicals, Inc.

    2008-04-01

    To evaluate whether a compelling desire to void (CDV) is always perceived suddenly, or whether it can result from the gradual build-up of bladder-filling sensations. The pattern of filling sensations was evaluated during standard cystometric bladder filling in 75 patients who complained of urgency and showed detrusor overactivity during cystometry. Cystometric filling ended when a CDV was reported. The 'warning volume' is defined as the difference in volume between the first perception of filling and the volume at CDV. Different patterns of bladder-filling sensations were reported. A CDV occurred suddenly, without a preceding sensation in 13% of the patients, whereas 66% reported at least two normal preceding filling sensations before a CDV. The bladder volume at the CDV was significantly smaller in patients that reported no or just one preceding sensation compared with those that reported the normal pattern of two or three sensations (P perception was reported was not different regardless of whether it was described as a first sensation of filling, a first desire or a CDV (P = 0.42). The warning volumes were not different between patients with one or no standardized filling sensations (P = 0.7), but they were significantly smaller than in patients with two or three filling sensations (P = 0.85). A CDV can occur suddenly if normal filling sensation is disturbed, but also gradually if normal filling sensation is preserved. In cases of disturbed filling sensation, the volume at CDV and the warning volume are significantly lower.

    To explore the joint diagnostic value of four temperature sensation tests in elderly patients with type 2 diabetic peripheral neuropathy. Thermal sensory analyzer-II were applied to measure cool sensation (CS), warm sensation (WS), cold pain sensation (CP)and heat pain sensation (HP) of 308 elderly patients with type 2 diabetes. Logistic regression model was adopted to create the new variable Temp4 from four temperature sensation tests to diagnose type 2 diabetic peripheral neuropathy. The ROC curve analysis was used to determine the best cut-off points of the four temperature sensation and Temp4, and the diagnostic value of it was evaluated. The means of temperature sensation tests of the diabetic peripheral neuropathy (DPN) group were significantly different from those of the non-DPN group (P sensation tests to diagnose the DPN, the sensitivity of WS test was the highest, and the value was 0.710; but the specificity, positive predictive value, negative predictive value, Youden index, diagnostic accuracy and Kappa value of cold sensation test were the highest, and the values were 0.842, 0.746, 0.799, 0.528, 77.92% and 0.535, respectively; the Kappa values of the other three temperature sensation tests were all greater than 0.4 (P sensation tests (P sensation quantitative tests were in good agreementand could be applied to diagnose DPN; the new variable Temp4 could be used for diagnosis of DPN with a higher diagnostic accuracy.

  10. Reversible induction of phantom auditory sensations through simulated unilateral hearing loss.

    Directory of Open Access Journals (Sweden)

    Roland Schaette

    Full Text Available Tinnitus, a phantom auditory sensation, is associated with hearing loss in most cases, but it is unclear if hearing loss causes tinnitus. Phantom auditory sensations can be induced in normal hearing listeners when they experience severe auditory deprivation such as confinement in an anechoic chamber, which can be regarded as somewhat analogous to a profound bilateral hearing loss. As this condition is relatively uncommon among tinnitus patients, induction of phantom sounds by a lesser degree of auditory deprivation could advance our understanding of the mechanisms of tinnitus. In this study, we therefore investigated the reporting of phantom sounds after continuous use of an earplug. 18 healthy volunteers with normal hearing wore a silicone earplug continuously in one ear for 7 days. The attenuation provided by the earplugs simulated a mild high-frequency hearing loss, mean attenuation increased from 30 dB at 3 and 4 kHz. 14 out of 18 participants reported phantom sounds during earplug use. 11 participants presented with stable phantom sounds on day 7 and underwent tinnitus spectrum characterization with the earplug still in place. The spectra showed that the phantom sounds were perceived predominantly as high-pitched, corresponding to the frequency range most affected by the earplug. In all cases, the auditory phantom disappeared when the earplug was removed, indicating a causal relation between auditory deprivation and phantom sounds. This relation matches the predictions of our computational model of tinnitus development, which proposes a possible mechanism by which a stabilization of neuronal activity through homeostatic plasticity in the central auditory system could lead to the development of a neuronal correlate of tinnitus when auditory nerve activity is reduced due to the earplug.

    Full Text Available Protection of asylum seeker and Illegal migrants human rights, has often been difficult due to the need of states to regulate unwanted migration flows. European Court of Human Rights plays an important role in protecting the rights of these individuals, through a set of human rights. Requests for interim measures under Rule 39 of the Rules of Court also have great importance. In cases involving illegal migrants and asylum-seekers, Court was often in difficult position, given the contradictions that could arise from the protection of human rights and the legitimate aim of the Contracting States to control the entry, residence and expulsion of aliens. Recent Courts judgment in case of M. S. S. against Belgium is particularly important, because of its remarkable influence on the perception of a common asylum system in the EU, as well as the judgment in the case of Jama Hirsi and Others v. Italy.

    2010-04-01

    Different tests can be used to evaluate lower urinary tract (LUT) sensation. The purpose of this study is to compare sensory tests in patients with voiding disorders. Seventy patients with various functional disorders of the LUT were admitted for a cystometry and an electrical perception threshold test of the bladder (bEPT) and distal urethra (uEPT). A pudendal EPT (pEPT) and pudendal somatosensory evoked potentials (pSSEP) were also determined. Correlations were calculated for somatosensory (uEPT, pEPT and pSSEP latency) and viscerosensory tests (volumes at filling sensations and bEPT). Fifty of the 70 patients (71%) had normal bladder filling sensations, with abnormal bEPT in 21/50 (41%), including 11 (22%) with no sensation at maximal electrical stimulation. Twenty out of 70 (29%) had an abnormal pattern of filling sensation, with increased bEPT in 13/20 (65%) and no sensation at electrical stimulation in 8/13 (40%). No significant correlation exists between filling sensation and bladder electrical perception thresholds (r 0.243). pEPT correlated with uEPT and SSEP (r > 0.035, p sensation. No significant correlation exists between volumes of filling sensations and bEPT (r 0.243). Therefore, both tests provide complementary information. Somatosensory tests of the pudendal nerve are correlated, so performing SSEP, pEPT and uEPT provides poor additional information to one of these tests alone. Somatosensory pudendal tests cannot be used to quantify filling sensation.

    Altered sensation (including paresthesia, dysesthesia and hypoesthesia) after mandibular implant surgery may indicate transient or permanent injury of the inferior alveolar nerve and the mental branch, and considerably lower patients’ satisfaction about the therapy. Previous studies have shown a great degree of variability on the incidence of altered sensation. We here reported the incidence of altered sensation after mandibular implant surgery based on a meta-analysis of 26 articles published between 1990.1.1 and 2016.1.1. Study quality and risk of bias was assessed and the studies with a lower score were excluded in the meta-analysis. Data synthesis was performed using the logistic-normal random-effect model. The meta-analyses revealed that the short-term (10 days after implant placement) and long-term (1 year after implant placement) incidence was 13% (95% CI, 6%-25%) and 3% (95% CI, 1%-7%), respectively. (2) For the patients who initially reported altered sensation, 80% (95% CI, 52%-94%) of them would return to normal sensation within 6 months after surgery, and 91% (95% CI, 78%-96%) of them would return to normal sensation one year after surgery. We concluded that dentist-patient communication about the risk of altered sensation is critical to treatment planning, since the short-term incidence of altered sensation is substantial (13%). When a patient reports altered sensation, regular assessment for 6 months would help tracing the changes of symptoms. In terms of long-term follow-up (1 year after surgery), the incidence is much lower (3%) and most patients (91%) would return to normal sensation. PMID:27100832

    Forced displacement related to persecution and violent conflict has reached a new peak in recent years. The primary aim of this study is to provide an initial overview of the acute and chronic health care problems of asylum seekers from the Middle East, with special emphasis on asylum seekers from Syria. Our retrospective data analysis comprised adult patients presenting to our emergency department between 01.11.2011 and 30.06.2014 with the official resident status of an "asylum seeker" or "refugee" from the Middle East. In total, 880 patients were included in the study. Of these, 625 (71.0%) were male and 255 (29.0%) female. The median age was 34 (range 16-84). 222 (25.2%) of our patients were from Syria. The most common reason for presentation was surgical (381, 43.3%), followed by medical (321, 36.5%) and psychiatric (137, 15.6%). In patients with surgical presentations, trauma-related problems were most common (n = 196, 50.6%). Within the group of patients with medical presentation, acute infectious diseases were most common (n = 141, 43.9%), followed by neurological problems (n = 70, 21.8%) and gastrointestinal problems (n = 47, 14.6%). There were no differences between Syrian and non-Syrian refugees concerning surgical or medical admissions. The most common chronic disorder of unclear significance was chronic gastrointestinal problems (n = 132, 15%), followed by chronic musculoskeletal problems (n = 108, 12.3%) and chronic headaches (n = 78, 8.9%). Patients from Syria were significantly younger and more often suffered from a post-traumatic stress disorder than patients of other nationalities (pSyria when compared to other nationalities of asylum seekers from the Middle East.

In this paper, we outline a qualitative component of a study in South Australia examining these links. Specifically, interviews were conducted with 50 refugees and asylum seekers who were purposively sampled according to gender, continent and visa status, from a broader survey. Interviews were analysed thematically. The results indicated that housing was of central importance to health and wellbeing and impacted on health through a range of pathways including affordability, the suitability of housing in relation to physical aspects such as condition and layout, and social aspects such as safety and belonging and issues around security of tenure. Asylum seekers in particular reported that living in housing in poor condition negatively affected their health. Our research reinforces the importance of housing for both the physical and mental health for asylum seekers and refugees living in resettlement countries. Improving housing quality, affordability and tenure security all have the potential to lead to more positive health outcomes.

    Full Text Available Abstract Background This article discusses the design of a study on the prevalence of health problems (both physical and mental and the utilisation of health care services among asylum seekers and refugees in the Netherlands, including factors that may be related to their health and their utilisation of these services. Methods/Design The study will include random samples of adult asylum seekers and refugees from Afghanistan, Iran and Somali (total planned sample of 600, as these are among the largest groups within the reception centres and municipalities in the Netherlands. The questionnaire that will be used will include questions on physical health (chronic and acute diseases and somatization, mental health (Hopkins Symptoms Checklist-25 and Harvard Trauma Questionnaire, utilisation of health care services, pre- and post-migratory traumatic experiences, life-style, acculturation, social support and socio-demographic background. The questionnaire has gone through a translation process (translation and back-translation, several checks and a pilot-study and cross-cultural adaptation. Respondents will be interviewed by bilingual and bicultural interviewers who will be specifically trained for this purpose. This article discusses the selection of the study population, the chosen outcome measures, the translation and cross-cultural adaptation of the measurement instrument, the training of the interviewers and the practical execution of the study. The information provided may be useful for other researchers in this relatively new field of epidemiological research among various groups of asylum seekers and refugees.

  20. A Home at the End of the World: Eritrean and Sudanese Asylum Seekers in Tel Aviv, Israel

    Full Text Available This paper explores the ways in which national culture intersects with urban environs to produce multinational subjectivity. Specifically, this paper shows the activity of Eritrean and Sudanese asylum seekers in Tel Aviv, Israel, as particularly generative of the life world building of Southern Tel Aviv (known as Little Africa. Juxtaposing these spaces of urban life, this paper also looks at the Holot Detention Facility as a space of life as well, situating the asylum seeker along various, migratory paths towards citizenship. With the near-total recreation of African life, this paper examines the Neve Sha’anan neighborhood as supportive of the LGBT and migrant communities, evidencing the flourishing of national culture outside of traditional boundaries. Particularly, this paper looks at “The Prevention of Infiltration Law” to discuss ideas of “infiltrators” using frameworks from Foucault, Merleau-Ponty, Levinas, Jean-Luc Nancy and Achille Mbembe. Examining ideas of space, place, ethics, embodiment, law, the body, street art, border fences, architecture, and minimalism, this paper juxtaposes BLM (Black Lives Matter and BDS (Boycott, Divestment, Sanctions from a transnational perspective of world-building, asking the question of where can one call a place, home.    Keywords: Tel Aviv, Eritrea, Sudan, asylum seekers, infiltration

    Evidence shows that job seekers tend to be attracted to employers known for their corporate social responsibility (CSR), but relatively little is known about the underlying psychological processes. Moreover, the literature is silent about whether and why some job seekers are unaffected, or even repelled by, an employer's CSR. We conducted a substantive replication of recent empirical support for three signal-based mechanisms by adapting the experimental manipulation used in a prior study while employing an alternative approach to analyzing a distinctly different type of data. We also extended prior work by examining other possible explanatory mechanisms and exploring potentially negative reactions to CSR. Using signaling theory as an overarching framework, we assessed research questions and tested hypotheses grounded in theories of employee recruitment and the psychology of CSR, specifying how an employer's CSR practices send signals from which job seekers draw inferences about unknown working conditions, thereby affecting their attraction to the employer. Study participants (N = 108) reviewed the webpages of two hiring companies and responded to open-ended questions about each employer. We content-analyzed written responses pertaining to one employer's webpages in which we embedded an experimental manipulation of information about the employer's community involvement or its environmentally sustainable practices. The results supported hypotheses that corroborate prior evidence for the "perceived value fit" and "expected employee treatment" mechanisms, and provided some, but relatively limited, support for the "anticipated pride" mechanism. Assessment of research questions highlighted previously undiscovered signal-based mechanisms that might help explain job seekers' attraction to CSR (e.g., inferences about the employer's positive work environment and financial standing, and the nature of its employees). Results also showed that a few people were less attracted

Although classical conditioning of the fatigue sensation has been reported in rats, there have been no reports in humans. Our aim was to examine whether classical conditioning of the mental fatigue sensation can take place in humans and to clarify the neural mechanisms of fatigue sensation using magnetoencephalography (MEG).

    The emotion-associated bodily sensation map is composed of a specific topographical distribution of bodily sensations to categorical emotions. The present study investigated whether or not interoceptive accuracy was associated with topographical changes in this map following emotion-induced bodily sensations. This study included 31 participants who observed short video clips containing emotional stimuli and then reported their sensations on the body map. Interoceptive accuracy was evaluated with a heartbeat detection task and the spatial patterns of bodily sensations to specific emotions, including anger, fear, disgust, happiness, sadness, and neutral, were visualized using Statistical Parametric Mapping (SPM) analyses. Distinct patterns of bodily sensations were identified for different emotional states. In addition, positive correlations were found between the magnitude of sensation in emotion-specific regions and interoceptive accuracy across individuals. A greater degree of interoceptive accuracy was associated with more specific topographical changes after emotional stimuli. These results suggest that the awareness of one’s internal bodily states might play a crucial role as a required messenger of sensory information during the affective process. PMID:28877218

    Adolescent substance use carries a considerable public health burden, and early initiation into use is especially problematic. Research has shown that trait sensation seeking increases risk for substance use initiation, but less is known about contextual factors that can potentially unmask this risk. This study utilized a diverse longitudinal subsample of youth (N = 454) from a larger study of familial alcoholism (53.1% female, 61% non-Hispanic Caucasian, 27.8% Hispanic, 11.2% other ethnicity). Study questions examined sensation seeking in early adolescence (mean age = 12.16) and its relations with later substance use initiation (mean age = 15.69), and tested whether neighborhood disadvantage moderated sensation seeking's effects on initiation of alcohol, tobacco, and marijuana use. Neighborhood disadvantage significantly moderated the relation between sensation seeking and all three forms of substance use. For the most part, sensation seeking effects were weakened as neighborhood disadvantage increased, with the most advantaged neighborhoods exhibiting the strongest link between sensation seeking and substance use initiation. These results highlight the importance of focusing on relatively advantaged areas as potentially risky environments for the sensation seeking pathway to substance use.

    Somatosensation plays a critical role in the dexterous manipulation of objects, in emotional communication, and in the embodiment of our limbs. For upper-limb neuroprostheses to be adopted by prospective users, prosthetic limbs will thus need to provide sensory information about the position of the limb in space and about objects grasped in the hand. One approach to restoring touch and proprioception consists of electrically stimulating neurons in somatosensory cortex in the hopes of eliciting meaningful sensations to support the dexterous use of the hands, promote their embodiment, and perhaps even restore the affective dimension of touch. In this review, we discuss the importance of touch and proprioception in everyday life, then describe approaches to providing artificial somatosensory feedback through intracortical microstimulation (ICMS). We explore the importance of biomimicry--the elicitation of naturalistic patterns of neuronal activation--and that of adaptation--the brain's ability to adapt to novel sensory input, and argue that both biomimicry and adaptation will play a critical role in the artificial restoration of somatosensation. We also propose that the documented re-organization that occurs after injury does not pose a significant obstacle to brain interfaces. While still at an early stage of development, sensory restoration is a critical step in transitioning upper-limb neuroprostheses from the laboratory to the clinic. Copyright © 2014 Elsevier Inc.

    Hand prostheses that are currently available on the market are used by amputees to only a limited extent, partly because of lack of sensory feedback from the artificial hand. We report a pilot study that showed how amputees can experience a robot-like advanced hand prosthesis as part of their own body. We induced a perceptual illusion by which touch applied to the stump of the arm was experienced from the artificial hand. This illusion was elicited by applying synchronous tactile stimulation to the hidden amputation stump and the robotic hand prosthesis in full view. In five people who had had upper limb amputations this stimulation caused referral touch sensation from the stump to the artificial hand, and the prosthesis was experienced more like a real hand. We also showed that this illusion can work when the amputee controls the movements of the artificial hand by recordings of the arm muscle activity with electromyograms. These observations indicate that the previously described "rubber hand illusion" is also valid for an advanced hand prosthesis, even when it has a robotic-like appearance.

  9. The molecular and cellular basis of cold sensation.

    Of somatosensory modalities, cold is one of the more ambiguous percepts, evoking the pleasant sensation of cooling, the stinging bite of cold pain, and welcome relief from chronic pain. Moreover, unlike the precipitous thermal thresholds for heat activation of thermosensitive afferent neurons, thresholds for cold fibers are across a range of cool to cold temperatures that spans over 30 °C. Until recently, how cold produces this myriad of biological effects has been poorly studied, yet new advances in our understanding of cold mechanisms may portend a better understanding of sensory perception as well as provide novel therapeutic approaches. Chief among these was the identification of a number of ion channels that either serve as the initial detectors of cold as a stimulus in the peripheral nervous system, or are part of rather sophisticated differential expression patterns of channels that conduct electrical signals, thereby endowing select neurons with properties that are amenable to electrical signaling in the cold. This review highlights the current understanding of the channels involved in cold transduction as well as presents a hypothetical model to account for the broad range of cold thermal thresholds and distinct functions of cold fibers in perception, pain, and analgesia.

  10. Disorders of saliva production and taste sensation after oropharyngeal irradiation

    Salivary secretion and disorders of taste sensation during and after radiotherapy of the oropharyngeal region were investigated in 20 patients. Salivary glands and tongue were exposed to radiation in different extent. Telecobalt irradiations were given in daily doses of 1.8 - 2.0 Gy, the total dose being 55 - 60 Gy in the salivary glands (1,590 - 1,760 ret). The patients were asked for subjective statements on salivary secretion, taste disorders were measured by semiquantitative gustometry with different dilution ratios for the four basis qualities of taste. 2 weeks after the onset of irradiation (20.0 Gy) a reduction of saliva production appeared without tendency of recovery. A statistically significant increase of the taste threshold appeared for all qualities of taste after 20 - 30 Gy. The criterion 'bitter' was primarily affected. This radiogen disorder, apparently caused on the cellular level of the taste buds, seems to be reversible also for doses of 60 Gy (1,760 ret) while radiogen functional disorders of the salivary glands are irreversible from 45 Gy (1,500 ret). Considering all sensual and organic effects of xerostomy (dental caries, osteoradionecrosis) it is advisable to keep the dose for at least one third of the salivary gland tissue below this critical value.

    1988-12-01

    In order to measure tinnitus induced by sodium salicylate injections, 84 pigmented rats, distributed among 14 groups in five experiments, were used in a conditioned suppression paradigm. In Experiment 1, all groups were trained with a conditioned stimulus (CS) consisting of the offset of a continuous background noise. One group began salicylate injections before Pavlovian training, a second group started injections after training, and a control group received daily saline injections. Resistance to extinction was profound when injections started before training, but minimal when initiated after training, which suggests that salicylate-induced effects acquired differential conditioned value. In Experiment 2 we mimicked the salicylate treatments by substituting a 7 kHz tone in place of respective injections, resulting in effects equivalent to salicylate-induced behavior. In a third experiment we included a 3 kHz CS, and again replicated the salicylate findings. In Experiment 4 we decreased the motivational level, and the sequential relation between salicylate-induced effects and suppression training was retained. Finally, no salicylate effects emerged when the visual modality was used. These findings support the demonstration of phantom auditory sensations in animals.

  12. Placebo-induced somatic sensations: a multi-modal study of three different placebo interventions.

    Full Text Available Somatic sensations induced by placebos are a frequent phenomenon whose etiology and clinical relevance remains unknown. In this study, we have evaluated the quantitative, qualitative, spatial, and temporal characteristics of placebo-induced somatic sensations in response to three different placebo interventions: (1 placebo irritant solution, (2 placebo laser stimulation, and (3 imagined laser stimulation. The quality and intensity of evoked sensations were assessed using the McGill pain questionnaire and visual analogue scales (VAS, while subjects' sensation drawings processed by a geographic information system (GIS were used to measure their spatial characteristics. We found that all three interventions are capable of producing robust sensations most frequently described as "tingling" and "warm" that can reach consider-able spatial extent (≤ 205 mm² and intensity (≤ 80/100 VAS. Sensations from placebo stimulation were often referred to areas remote from the stimulation site and exhibit considerable similarity with referred pain. Interestingly, there was considerable similarity of qualitative features as well as spatial patterns across subjects and placebos. However, placebo laser stimulation elicited significantly stronger and more widespread sensations than placebo irritant solution. Finally, novelty seeking, a character trait assessed by the Temperament and Character Inventory and associated with basal dopaminergic activity, was less pronounced in subjects susceptible to report placebo-induced sensations. Our study has shown that placebo-induced sensations are frequent and can reach considerable intensity and extent. As multiple somatosensory subsystems are involved despite the lack of peripheral stimulus, we propose a central etiology for this phenomenon.

    Acupuncture sensation and manipulation have been considered to be an important component of acupuncture in traditional Asian medicine. However, there has been limited research as to whether acupuncture sensation is associated with therapeutic benefit. This study investigated the relationship between acupuncture sensation and analgesic effect according to acupuncture manipulation. Fifty-three healthy volunteers received three different forms of acupuncture in a single-blinded crossover design: superficial needling (0.3 cm), deep needling (2 cm) and needling with bi-directional rotation. The effects of acupuncture were evaluated by using the pressure pain threshold. Acupuncture sensation measurement was done in two ways. Both total acupuncture sensation and increase of the pressure pain threshold were maximum in needling with rotation, followed by deep needling and superficial needling. Repeated-measure analysis of variance (ANOVA) analysis was carried out to assess whether there was a significant difference; both showed significant difference (p = 0.000, 0.003). A paired sample t-test was carried out, which revealed that needling with rotation showed significant difference from both superficial needling and deep needling. Further, the correlation between the total acupuncture sensation and changes in pressure pain threshold were calculated using Pearson correlation; there was a significant correlation (p = 0.002, p = 0.013). Acupuncture sensation and pressure pain threshold increase according to the depth and rotation of acupuncture. Especially, both display significant increase with needle rotation. Further, there is a significant correlation between acupuncture needling sensation and increase in pressure pain threshold. It seems that needle rotation and acupuncture sensation play an important role in verifying the effect of acupuncture. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Individuals who seek asylum are frequently fleeing violent persecution and may experience head injury (HI). However, little is known about the prevalence of HI in asylum seekers and refugees (ASR) despite the potential for HI to significantly affect cognitive and emotional functioning and to compromise asylum outcomes. This preliminary study investigates the prevalence of HI in ASR referred to a complex psychological trauma service. Participants were 115 adult ASR referred to a community psychological trauma service with moderate to severe mental health problems associated with psychological trauma. They were screened for a history of HI using a questionnaire developed for the study. Interpreters were used when required. The overall prevalence of HI was 51%. At least 38% of those with HI had a moderate-severe HI that could cause persisting disability. In 53% of those with HI, the cause was torture, human trafficking or domestic violence. Repeat HI can have cumulative effects on function; it was common, and was reported in 68% of those with HI. An injury to the head was not known to mental health clinicians prior to screening in 64% of cases. The emotional and cognitive consequences of HI in ASR may increase the vulnerability of this disadvantaged group, and can be associated with neurobehavioural problems affecting daily life and may compromise asylum outcomes. Routine screening for HI in ASR is needed, as are links to neuropsychology and brain injury services for advice, assessment and intervention.

    2015-01-01

    Individuals with cocaine use disorder chronically self-administer cocaine to the detriment of other rewarding activities, a phenomenon best modeled in laboratory drug-choice procedures. These procedures can evaluate the reinforcing effects of drugs versus comparably valuable alternatives under multiple behavioral arrangements and schedules of reinforcement. However, assessing drug-choice in treatment-seeking or abstaining humans poses unique challenges: for ethical reasons, these populations typically cannot receive active drugs during research studies. Researchers have thus needed to rely on alternative approaches that approximate drug-choice behavior or assess more general forms of decision-making, but whether these alternatives have relevance to real-world drug-taking that can inform clinical trials is not well-understood. In this mini-review, we (A) summarize several important modulatory variables that influence cocaine choice in nonhuman animals and non-treatment seeking humans; (B) discuss some of the ethical considerations that could arise if treatment-seekers are enrolled in drug-choice studies; (C) consider the efficacy of alternative procedures, including non-drug-related decision-making and ‘simulated’ drug-choice (a choice is made, but no drug is administered) to approximate drug choice; and (D) suggest opportunities for new translational work to bridge the current divide between preclinical and clinical research.

    2003-10-01

    This paper is a case study in public health ethics. It considers whether there is a basis in ethics for political action by health professionals and their associations in response to inhumane treatment. The issue arises from Australia's treatment of asylum seekers and the charge that this treatment has been both immoral and inhumane. This judgement raises several questions of broader significance in bioethics and of significance to the emerging field of public health ethics. These questions relate to the role of health professionals in response to inhumane treatment of people in their charge; to the discipline of public health in light of a growing recognition of its ethical basis; and the role of public health and bioethical associations in response to ethical issues arising in a political context. It is argued that, in serious cases of humanitarian and human rights abuses affecting health and well-being, there is a case for political action by health professionals, academic and professional institutions, and associations of public health and ethics.

    Individuals fleeing persecution have the right to asylum. This most fundamental right was guaranteed by the 1951 United Nations (UN) Convention Relating to the Status of Refugees and was implemented in the 1967 UN protocol regarding refugee status. The United States codified refugee protection and the procedures for asylum in the Refugee Act of 1980, which was made part of the Immigration and Nationality Act (INA). In claiming refugee status, the burden of proof rests with the asylum seeker and is often a daunting task, given language and cultural barriers, lack of knowledge about U.S. legal procedures, and the reality that oppressive states do not document their intentions to persecute dissidents. Forensic psychiatrists may be asked to provide mental health assessment in immigration cases. In this article, an example of a Central American man with a nontraditional but increasingly common request for asylum is presented, the asylum process is described, and the role of the forensic psychiatric expert before the immigration court is explored.

    The negative psychological impacts of working with traumatised people are well documented and include vicarious traumatisation (VT): the cumulative effect of identifying with clients' trauma stories that negatively impacts on service providers' memory, emotions, thoughts, and worldviews. More recently, the concept of vicarious resilience (VR) has been also identified: the strength, growth, and empowerment experienced by trauma workers as a consequence of their work. VR includes service providers' awareness and appreciation of their clients' capacity to grow, maintaining hope for change, as well as learning from and reassessing personal problems in the light of clients' stories of perseverance, strength, and growth. This study aimed at exploring the experiences of mental health, physical healthcare, and settlement workers caring for refugees and asylum seekers in South Australia. Using a qualitative method (data-based thematic analysis) to collect and analyse 26 semi-structured face-to-face interviews, we identified four prominent and recurring themes emanating from the data: VT, VR, work satisfaction, and cultural flexibility. These findings-among the first to describe both VT and VR in Australians working with refugee people-have important implications for policy, service quality, service providers' wellbeing, and refugee clients' lives. © The Author(s) 2015.

  19. Spirituality, hope, and self-sufficiency among low-income job seekers.

    Science.gov (United States)

    2015-04-01

    Self-sufficiency (SS) is an important social welfare policy goal in the United States, yet little is known about the process that leads to SS. To address this gap in the literature, this study examined the relationship between spirituality, hope, and SS among a sample of low-income job seekers (N = 116). It was hypothesized that spirituality would be related to hope, and that hope, in turn, would be related to SS. Using survey data from two workforce development agencies, this hypothesis was confirmed-hope fully mediated the relationship between spirituality and SS. Of the two factors through which hope is commonly operationalized-agency and pathways-supplemental analysis suggested that spirituality only affects SS through the agency channel. To help foster hope in direct practice settings, it is suggested that social workers might employ spiritually modified cognitive-behavioral therapy protocols. Macrostructural interventions that block the pathway component of hope are also suggested to help reverse exclusion from labor market entry. As such, hope needs to be addressed comprehensively-intrapsychically and macrostructurally-to effect bottom-up change for SS. Engendering hope may assist clients overcome some of the many challenges they encounter on the journey to SS.

    Most research on racial/ethnic differences among smokers is outdated and does not focus on help seekers. The purpose of this study was to revisit racial/ethnic differences in variables related to cessation in a sample of smokers enrolled in a randomized trial. Adult smokers (N = 417; n = 126 White; n = 123 Hispanic; n = 168 Black) completed measures of demographics, smoking history, alcohol use, depressive symptoms, and readiness to quit. We found significant differences in these factors across groups. Blacks were more likely to be older, less educated, single, low income, smoke menthol cigarettes, and report greater nicotine dependence. Hispanics were younger, reported fewer years smoking and cigarettes per day, lower nicotine dependence, preferred mentholated cigarettes, and reported greater alcohol use intensity. After controlling for demographics and smoking history, Blacks reported greater depressive symptoms and lower readiness to quit compared with Whites and Hispanics. Help-seeking Blacks may exhibit more risk factors for difficulty quitting compared with other groups. Hispanics may have some protective factors, such as lower dependence, but require attention to alcohol use and menthol smoking. Identifying preintervention racial/ethnic differences in characteristics related to cessation is important for developing evidence-based and culturally specific interventions and for reducing tobacco-related health disparities.

    Full Text Available A phased array radar seeker (PARS must be able to effectively decouple body motion and accurately extract the line-of-sight (LOS rate for target missile tracking. In this study, the real-time two-channel beam pointing error (BPE compensation method of PARS for LOS rate extraction is designed. The PARS discrete beam motion principium is analyzed, and the mathematical model of beam scanning control is finished. According to the principle of the antenna element shift phase, both the antenna element shift phase law and the causes of beam-pointing error under phantom-bit conditions are analyzed, and the effect of BPE caused by phantom-bit technology (PBT on the extraction accuracy of the LOS rate is examined. A compensation method is given, which includes coordinate transforms, beam angle margin compensation, and detector dislocation angle calculation. When the method is used, the beam angle margin in the pitch and yaw directions is calculated to reduce the effect of the missile body disturbance and to improve LOS rate extraction precision by compensating for the detector dislocation angle. The simulation results validate the proposed method.

    Drinking can occur because of expectations to drink (reasoned pathway) or because of willingness to drink under certain circumstances (reactive pathway). These pathways are thought to be influenced by different cognitions such as alcohol-related attitudes, norms, or drinking prototypes (Gerrard et al., 2008). Impulsive traits reflect individual differences in the influence of reasoned or reactive factors, however little research has investigated whether impulsivity moderates the effects of cognitive factors predicting alcohol use. We tested whether differences in three impulsivity traits (premeditation, sensation seeking and negative urgency) moderated associations of reasoned (risk/disapproval attitudes and social norms) and reactive (prototype) pathway variables on expectation/willingness to drink and recent alcohol use. We collected data from n = 409 college students; the sample was 67% female, 43% Asian American, with Mdnage = 19. Hypotheses were tested using multiple regression. Premeditation and sensation seeking moderated reasoned variable effects on expectation and drinking. Among those low on premeditation, risk attitudes were most associated with drinking expectation, with alcohol prototypes most related to recent drinking. These effects declined at higher premeditation levels. Among those high on sensation seeking, risk attitudes were most associated with expectation and drinking, declining at lower sensation seeking levels. There was little evidence of moderation predicting drinking willingness. Findings imply personality differences may explain association strength between reasoned but not reactive risk behavior pathways with alcohol outcomes. They have ramifications for personalized prevention programs to reduce drinking through cognition change, as alcohol-related cognition influence may differ depending on personality characteristics.

    This study examined the relationships between youth and parental sensation-seeking, peer influence, parental monitoring and youth risk involvement in adolescence using structural equation modeling. Beginning in grade-six, longitudinal data were collected from 543 students over three years. Youth sensation-seeking in grade six contributed to risk involvement in early adolescence (grades six and seven) indirectly through increased peer risk influence and decreased parental monitoring but did not have a direct contribution. It contributed directly and indirectly to risk involvement in middle adolescence (grades eight and nine). Parent sensation-seeking at baseline was positively associated with peer risk influence and negatively associated with parental monitoring; it had no direct effect on adolescent risk involvement. Parental monitoring buffers negative peer influence on adolescent risk involvement. Results highlight the need for intervention efforts to provide normative feedback about adolescent risky behaviors and to vary among families in which parents and/or youth have high sensation-seeking propensities.

    Quantitative relations between the sensations and the stimuli that produce them are the domain of psychophysics, a branch of natural science not yet known at the time of Immanuel Kant (1724-1804). But Kant's philosophical doctrines of perception imply that sensations can be quantified. Accordingly, he proposed not only to consider the magnitude of both sensations and stimuli but also to work out an appropriate mathematics that would relate these magnitudes to each other. This part of Kant's work received almost no attention up to the present time although it contains some essential elements of modern psychophysics.

    In our previous study, we proposed a objective measure, i.e., Booming Level for quantifying booming sensation caused by car interior noise. In this paper, Booming Level was modified with its weighting function and within the process of calculation 1/3 octave band level was modified for the best match with subjective result. These modifications were conducted through a subjective experiment rating booming sensation with sounds having much lower frequency contents below 63Hz. With this modified Booming Level, we have obtained higher correlation for rating booming sensation with sounds having prominent low frequency components. 1 ref., 10 figs.

  6. Body schema and midline sensation influenced by unilateral manual stimulation of lower extremity

    Relevance: Clinical experience advocates manual stimulation in order to increase the sensation of the body and adjust the body schema. Unilateral treatment may affect the midline sensation and weight distribution in a standing position, but little evidence is available to support this procedure...... alignment was seen as a response to unilateral massage. It may be suggested, that the manipulated midline sensation and weight distribution reflects a state in which the participant's attention to a greater extent has been directed towards a specific body part due to the manual sensory stimulation.

    We observed visual sensations (VSs) in patients undergoing intensity modulated radiotherapy (IMRT) of the brain without the beam passing through ocular structures. We analyzed this phenomenon especially with regards to reproducibility, and origin. Analyzed were ten consecutive patients (aged 41-71 years) with glioblastoma multiforme who received pulsed IMRT (total dose 60Gy) with helical tomotherapy (TT). A megavolt-CT (MVCT) was performed daily before treatment. VSs were reported and recorded using a triggered event recorder. The frequency of VSs was calculated and VSs were correlated with beam direction and couch position. Subjective patient perception was plotted on an 8x8 visual field (VF) matrix. Distance to the orbital roof (OR) from the first beam causing a VS was calculated from the Dicom radiation therapy data and MVCT data. During 175 treatment sessions (average 17.5 per patient) 5959 VSs were recorded and analyzed. VSs occurred only during the treatment session not during the MVCTs. Plotting events over time revealed patient-specific patterns. The average cranio-caudad extension of VS-inducing area was 63.4mm (range 43.24-92.1mm). The maximum distance between the first VS and the OR was 56.1mm so that direct interaction with the retina is unlikely. Data on subjective visual perception showed that VSs occurred mainly in the upper right and left quadrants of the VF. Within the visual pathways the highest probability for origin of VSs was seen in the optic chiasm and the optic tract (22%). There is clear evidence that interaction of photon irradiation with neuronal structures distant from the eye can lead to VSs.

    94 delinquents in two homes for resocialization were surveyed to elucidate the relationship among the status of volatile solvent inhalation, expectancy and personality. The subjects were classified into solvent-inhalation group and non-solvent-inhalation group, and the former was divided into solvent dependence group and abuse group according to DSM-III-R. Each group was given personality tests; general health questionnaire (GHQ), sensation seeking scale (SSS), the vividness of visual imagery (VVIQ), test of visual imagery control (TVIC) and Yatabe-Guilford test (YG). In addition we investigated expectancy and mental symptoms caused by inhalation in it. The results are summarized as follows; 1. Inhalation group scored higher on SSS than non-inhalation group. 2. Compared with abuse group, dependence group presented with 1) higher GHQ score meaning neurotic tendency; 2) higher TVIC score meaning imagery-control-ability; 3) a higher incidence of day-dream and hallucination, especially egosyntonic type; 4) higher expectancy of "enhancement of positive affection", "reduction of negative affection" and "hallucination seeking"; 5) lower expectancy of "association with friends". 3. Higher scored inhalers on TVIC showed visual hallucinations, especially egosyntonic type more frequently than lower ones. 4. Significant correlations were recognized between GHQ score and expectancy of "reduction of negative affection", and between lack of objectiveness score of YG subscale and "hallucination seeking" expectancy. These results suggested that 1) beginning of inhalation is associated with sensation seeking trait, 2) progression to solvent dependence is correlated with three expectancies, i.e., seeking egosyntonic hallucinations paralleling high imagery-control-ability and subjectivity, reducing negative affection paralleling neurotic tendency, and enhancing positive affection. According to the findings, indulgence to drug induced positive imagery led delinquents into splitting of

    In this study, bullying is examined in light of the “prosocial security hypothesis”— i.e., the hypothesis that insecure attachment, with temperamental dispositions such as sensation seeking, may foster individualistic, competitive value orientations and problem behaviors. A group of 375 Italian students (53% female; Mean age = 12.58, SD = 1.08) completed anonymous questionnaires regarding attachment security, social values, sensation seeking, and bullying behaviors. Path analysis showed that attachment to mother was negatively associated with bullying of others, both directly and through the mediating role of conservative socially oriented values, while attachment to father was directly associated with victimization. Sensation seeking predicted bullying of others and victimization both directly and through the mediating role of conservative socially oriented values. Adolescents’ gender affected how attachment moderated the relationship between sensation seeking and problem behavior. PMID:29535668

    A substantial number of adolescents are current and regular cigarette smokers, and there is a need to better understand factors that contribute to smoking behavior during these years. Sensation seeking (SS) is one factor that has consistently been associated with smoking, but less is known about mechanisms that may explain this relationship. The present study tested the hypothesis that high school students high in SS would report heavier cigarette smoking and that this relationship would be mediated by negative affect and by perceptions about the risks of smoking. Students (n = 1,688) participated in an annual survey of substance use and related attitudes and characteristics. As expected, higher SS was associated with greater levels of past 30-day (odds ratio [OR] = 1.46, p = .004) and lifetime (OR = 1.37, p = .004) smoking, particularly for males. Multiple mediation models indicated that effect of SS on both 30-day (combined indirect effect z = 5.38, p perception. These findings suggest a need for increasing the sensation value of anti-tobacco messages to increase their efficacy for high SS youth. High SS youth may also benefit from prevention efforts designed to teach healthy ways of coping with negative affect.

    The objective of the study was to assess the impact of protein composition and/or fibre enrichment of yogurt on appetite sensations and subsequent energy intake. In this double-blind crossover study, 20 healthy men (aged 32.4 ± 9.1 years) were submitted to 5 randomized testing sessions, during which they had to consume 5 isocaloric and isonproteinemic yogurt snacks (120-g servings, ∼230 kJ, ∼4.5 g protein) differing by their casein-to-whey protein ratio (C:W) or dietary fibre content: (i) control C:W = 2.8:1; (ii) high whey (HW) C:W = 1.5:1, and fibre-enriched formulations using control; (iii) 2.4 g of inulin; (iv) 1.9 g of inulin and 0.5 g of β-glucan (+IN-βG); and (v) 0.5 g of β-glucan. Appetite sensations were assessed using 150-mm visual analog scales. Plasma variables (glucose, insulin, ghrelin) were measured at 30-min intervals post-yogurt consumption for 2 h. Finally, energy intakes during ad libitum lunches offered 2 h after yogurt snacks were recorded. None of the yogurts impacted appetite sensations. Ad libitum energy intake was significantly different only between HW and control yogurts (-812 kJ; p = 0.03). Regarding post-yogurt plasma variables, a significant difference was found only between ghrelin area under the curve of the +IN-βG and the HW yogurts (-15 510 pmol/L per 120 min, p = 0.04). In conclusion, although appetite sensations were not influenced by variations in yogurts' protein compositions, a reduced energy intake was observed during the ad libitum lunch after the HW yogurt that may be attributable to its lower C:W. Surprisingly, the fibre enrichments studied did not exert effect on appetite sensations and energy intake.

    Thermal comfort in traditionally uniform environment is apparent and can be improved by increasing energy expenses. To save energy, non-uniform environment implemented by personalized conditioning system attracts considerable attention, but human response in such environment is unclear. To investigate regional- and whole-body thermal sensation and comfort in a cool environment with personalized heating. In total 36 subjects (17 males and 19 females) including children, adults and the elderly, were involved in our experiment. Each subject was first asked to sit on a seat in an 18°C chamber (uniform environment) for 40min and then sit on a heating seat in a 16°C chamber (non-uniform environment) for another 40min after 10min break. Subjects' regional- and whole-body thermal sensation and comfort were surveyed by questionnaire and their skin temperatures were measured by wireless sensors. We statistically analyzed subjects' thermal sensation and comfort and their skin temperatures in different age and gender groups and compared them between the uniform and non-uniform environments. Overall thermal sensation and comfort votes were respectively neutral and just comfortable in 16°C chamber with personalized heating, which were significantly higher than those in 18°C chamber without heating (pthermal sensation and comfort was consistent in subjects of different age and gender. However, adults and the females were more sensitive to the effect of personalized heating and felt cooler and less comfort than children/elderly and the males respectively. Variations of the regional thermal sensation/comfort across human body were consistent with those of skin temperature. Personalized heating significantly improved human thermal sensation and comfort in non-uniform cooler environment, probably due to the fact that it increased skin temperature. However, the link between thermal sensation/comfort and variations of skin temperature is rather complex and warrant further

    A hybrid modality brain-computer interface (BCI) is proposed in this paper, which combines motor imagery with selective sensation to enhance the discrimination between left and right mental tasks, e.g., the classification between left/ right stimulation sensation and right/ left motor imagery. In this paradigm, wearable vibrotactile rings are used to stimulate both the skin on both wrists. Subjects are required to perform the mental tasks according to the randomly presented cues (i.e., left hand motor imagery, right hand motor imagery, left stimulation sensation or right stimulation sensation). Two-way ANOVA statistical analysis showed a significant group effect (F (2,20) = 7.17, p = 0.0045), and the Benferroni-corrected multiple comparison test (with α = 0.05) showed that the hybrid modality group is 11.13% higher on average than the motor imagery group, and 10.45% higher than the selective sensation group. The hybrid modality experiment exhibits potentially wider spread usage within ten subjects crossed 70% accuracy, followed by four subjects in motor imagery and five subjects in selective sensation. Six subjects showed statistically significant improvement ( Benferroni-corrected) in hybrid modality in comparison with both motor imagery and selective sensation. Furthermore, among subjects having difficulties in both motor imagery and selective sensation, the hybrid modality improves their performance to 90% accuracy. The proposed hybrid modality BCI has demonstrated clear benefits for those poorly performing BCI users. Not only does the requirement of motor and sensory anticipation in this hybrid modality provide basic function of BCI for communication and control, it also has the potential for enhancing the rehabilitation during motor recovery.

    Vision, proprioception and plantar sensation contribute to the control of postural balance (PB). Reduced plantar sensation alters postural response and is at an increased risk of fall, and eye movements reduce the postural sway. Therefore, the aim of this study was to study the improvement of plantar sensation and PB after saccadic eye movement (SEM) and pursuit eye movement (PEM) in community-dwelling elderly women. Participants (104 females; 75.11 ± 6.25 years) were randomly allocated into the SEM group (n = 52) and PEM groups (n = 52). The SEM group performed eye fixation and SEM for 5 minutes, and the PEM group performed eye fixation and PEM for 5 minutes. The plantar sensation was measured according to the plantar surface area of the feet in contact with the floor surface before and after the intervention. Before and after SEM and PEM with the eyes open and closed, PB was measured as the area (mm(2)), length (cm), and velocity (cm/s) of the fluctuation of the center of pressure (COP). The plantar sensation of both feet improved in both groups (p eye open and close in both groups (p < 0.01). The length and velocity of the COP significantly decreased in the SEM group compared to the PEM group (p < 0.05). In conclusion, SEM and PEM are effective interventions for improving plantar sensation and PB in elderly women, with greater PB improvement after SEM.
