    African Journals Online (AJOL)

    Is Nigeria a possible terrorist haven? This article aims to answer this question from two perspectives: international and domestic terrorism. From the perspective of international terrorism and in the standpoint of Western liberalism, for a foreseeable future Nigeria cannot be a haven for terrorism. This is the impossibility ...

  2. Underfunding in Terrorist Organizations

    Science.gov (United States)

    Shapiro, Jacob N.; Siegel, David A.

    A review of international terrorist activity reveals a pattern of financially strapped operatives working for organizations that seem to have plenty of money. To explain this observation, and to examine when restricting terrorists’ funds will reduce their lethality, we model a hierarchical terror organization in which leaders delegate financial and logistical tasks to middlemen, but cannot perfectly monitor them for security reasons. These middlemen do not always share their leaders’ interests: the temptation exists to skim funds from financial transactions. When middlemen are sufficiently greedy and organizations suffer from sufficiently strong budget constraints, leaders will not fund attacks because the costs of skimming are too great. Using general functional forms, we find important nonlinearities in terrorists’ responses to government counter-terrorism. Restricting terrorists’ funds may be ineffective until a critical threshold is reached, at which point cooperation within terrorist organizations begins to break down and further government actions have a disproportionately large impact.

    Sixty patients of ages ranging from 11 to 64, with chronic urticaria from 2 months to 50 years duration, were studied with the provocation test. We found responses in 33.3% of patients. Tartrazine was the most common inducer, specially in those patients sensitive to aspirin with increased salicilate blood levels. As we did not use aspirin as inducer the results with tartrazine are more relevant and can be used to detect a positive response to aspirin. The relation between tartrazine and aspirin was not observed in patients with pressure or cholinergic urticaria. The provocation test is most useful in patients with chronic urticaria of unknown cause. 4 hydroxybenzoic acid and sodium acid and sodium benzoate were the more common inducers in the latter patients. We feel that the provocation test is a useful tool to study patients with chronic urticaria. Tartrazine, 4 hydroxybenzoic acid, sodium benzoate, tiramin and penicilin are included in the test. The responders should eliminate the offender from their diet.

It adopts a ‘criminality oriented approach’ that puts discrete pieces of terrorism under a microscopic examination and explains terrorist learning of criminality: how tacit knowledge required for terror tactics and organized crime is processed and saved in the secret domains of TOs and OCGs and how t...

  6. On Provocation, Education and Entrepreneurship

    2011-01-01

    This essay develops an affect-based theory of entrepreneurial entrepreneurship education, something we summarise in a model of provocation-based entrepreneurial entrepreneurship education (the E3 model). Taking its starting point in an anecdote that illustrates the importance of provocation...... in processes of learning entrepreneurship, this article responds to previous calls for less economised entrepreneurship education focusing on its creative-relational nature. An affect-based theory of E3 brings together provocation, deterritorialisation (uprooting) and decoding/imagination, which calls for both...... critique and creativity, and resonates with appreciations of paralogy as driver in learning processes. The implications of this conceptual model of learning entrepreneurship entrepreneurially are discussed, with particular focus on the role of the pedagogue and on the future of learning entrepreneurship....

    Terrorism can be carried out by the state or by its citizens. The latter may be labelled 'freedom fighters' or 'terrorists' depending on the political context. One of the most important aetiological factors driving Islamic terrorists is the experience of alienation and shame. This sense of being made to feel totally invalidated, of feeling worthless in the eyes of the other, is at the root of rage and violent revenge, implying that the way the current 'War on Terror' is being fought by the United States and the United Kingdom can only lead to more terrorism and danger for our society.

  11. Painful and provocative events scale and fearlessness about death among Veterans: Exploratory factor analysis.

    Science.gov (United States)

    2017-01-15

    The interpersonal theory of suicide suggests three proximal risk factors for suicide: perceived burdensomeness, thwarted belongingness, and acquired capability. Previous literature indicates that repetitive exposure to painful and provocative events is related to increased acquired capability for suicide. Despite this, research related to the assessment of painful and provocative events has been insufficient. Research has inconsistently administered the Painful and Provocative Events Scale (PPES; a painful and provocative events assessment), and no study has examined the factor structure of the English PPES. This study explored the factor structure of the PPES and the relation between factors and fearlessness about death. The sample was a cross-sectional, self-report study comprised of 119 Veterans (Mage = 46.5, SD = 13.5). Findings from an exploratory factor analysis indicated a four-factor solution for the PPES; however, no factor from the PPES significantly related to fearlessness about death (measured by the Acquired Capability for Suicide Scale - Fearlessness About Death Scale; all p >.21). Cross-sectional, small Veteran sample. Findings suggest that the PPES lacks the psychometric properties necessary to reliably investigate painful and provocative factors. Consequently, this measure may not reliably capture and explain how painful and provocative events relate to fearlessness about death, which is a barrier to improving suicide risk assessment and prediction. Recommendations for the construction of a new PPES are offered. Published by Elsevier B.V.

    Full Text Available This article aims to determine whether the Provocative Proactive (PP program on Metro TV proactive is known by Indonesian people, to explain how the media selection strategy for Provocative Proactive program is, and to explain the program on Metro TV can be written and known by the press or reporters (external PR. The method used was descriptive qualitative approach to analyze the existing problems by presentation of information from the data collected through the company's internal analysis of the results of in-depth interviews and field observations regarding activities in the company. The results showed that duties and functions of public relations are as a motor for better co-operation with external and internal parties relating to Provocative Proactive program. The PR and Promotion Departments were turned out to help the success of the PP program, in addition to various roles and hardworks of the Producer and the creative team. Based on the observations, the role of Metro TV’s PR and Promotion Departments in conducting media relations through cooperation with the media both print and electronic media in an effort to have Provocative Proactive widely known by the public is through cooperation with various mass media, implementation of mass media selection strategies, and introducing Provocative Proactive Program broadly.

    Emergency personnel are tasked with the daunting job of being the first to evaluate and manage victims of a terrorist attack. Numerous potential chemical agents could be used by terrorists. The challenge for first responders and local hospital emergency personnel is to prepare for a terrorist event that might use one or more of these agents. As part of that preparation, emergency physicians should have a basic understanding of potential chemical terrorist agents. It is beyond the scope of this article to review all potential terrorist agents. Rather, four potential agents have been chosen for review: sodium monofluoroacetate, trichothecene mycotoxins, vomiting agents, and saxitoxin.

  3. Nasal provocation test using allergen extract versus cold dry air provocation test: which and when?

    2013-01-01

    Nasal provocation tests (NPTs) are useful for evaluation of patients with allergic rhinitis. The cold dry air (CDA) provocation test is useful for evaluation of patients with nonspecific nasal hyperreactivity (NHR). This study aimed to determine whether the NPT or CDA provocation would be more useful for patients with different clinical pictures. We evaluated changes in nasal symptoms (visual analog scale [VAS]) and acoustic parameters after NPT or CDA provocation in healthy volunteers (group A, n = 27), patients with allergic rhinitis (group B, n = 20), and subjects with nonallergic rhinitis (group C, n = 26). According to their subjective cold hyperresponsiveness (SCH), we compared changes in VAS and acoustic parameters after each protocol. The correlation between results of the skin-prick test (SPT) and changes in VAS after each protocol was analyzed. Finally, we performed an analysis of correlation between NPT and CDA provocation. After NPT, group B showed a larger change in VAS for rhinorrhea, sneezing, and itching (p < 0.01). After CDA challenge, the change in VAS for nasal obstruction was larger in group C (p < 0.05). Changes in acoustic parameters were larger in groups B and C after NPT (p < 0.01). After CDA challenge, the SCH(+) group (n = 49) showed a larger decrease of acoustic parameters than the SCH(-) group (n = 24; p < 0.01). Significant correlation was observed between the size of SPT and degree of change in VAS after NPT. No significant correlation was observed between NPT and CDA. CDA could be an adjunct tool for evaluating NHR in patients with self-reported SCH.

  4. Philosophical Provocation: The Lifeblood of Clinical Ethics.

    Science.gov (United States)

    McCullough, Laurence B

    2017-02-01

    The daily work of the clinical ethics teacher and clinical ethics consultant falls into the routine of classifying clinical cases by ethical type and proposing ethically justified alternatives for the professionally responsible management of a specific type of case. Settling too far into this routine creates the risk of philosophical inertia, which is not good either for the clinical ethicist or for the field of clinical ethics. The antidote to this philosophical inertia and resultant blinkered vision of clinical ethics is sustained, willing exposure to philosophical provocation. The papers in this clinical ethics issue of the Journal of Medicine and Philosophy provide just such philosophical provocation related to core topics in clinical ethics: the distinction between clinical practice and clinical research; telemedicine, or medicine at a distance; illness narratives; the concept of the placebo effect; and sex reassignment. © The Author 2017.

    The Seldon terrorist model represents a multi-disciplinary approach to developing organization software for the study of terrorist recruitment and group formation. The need to incorporate aspects of social science added a significant contribution to the vision of the resulting Seldon toolkit. The unique addition of and abstract agent category provided a means for capturing social concepts like cliques, mosque, etc. in a manner that represents their social conceptualization and not simply as a physical or economical institution. This paper provides an overview of the Seldon terrorist model developed to study the formation of cliques, which are used as the major recruitment entity for terrorist organizations.

    Muhamet ALIU

    2017-03-01

    Full Text Available Terrorism financing is one of the most complex problems the democratic world is facing today. The transfer of funds to support terrorist activities has created enormous challenges across the world. This has fuelled several inter-religious and nationalist hate, and as such has put many nations into war with terrorist organisations. The main objective of this study is to review the sources of terrorist financing. The paper relies on secondary data that were drawn from various books, journals, as well as from institutional materials relevant to the issues raised. It concludes that terrorists are exploiting established financial systems at the global level to move their finances, and that informal systems remain the biggest challenge to thwart terrorist activities.

  11. A generative model for predicting terrorist incidents

    Verma, Dinesh C.; Verma, Archit; Felmlee, Diane; Pearson, Gavin; Whitaker, Roger

    2017-05-01

    A major concern in coalition peace-support operations is the incidence of terrorist activity. In this paper, we propose a generative model for the occurrence of the terrorist incidents, and illustrate that an increase in diversity, as measured by the number of different social groups to which that an individual belongs, is inversely correlated with the likelihood of a terrorist incident in the society. A generative model is one that can predict the likelihood of events in new contexts, as opposed to statistical models which are used to predict the future incidents based on the history of the incidents in an existing context. Generative models can be useful in planning for persistent Information Surveillance and Reconnaissance (ISR) since they allow an estimation of regions in the theater of operation where terrorist incidents may arise, and thus can be used to better allocate the assignment and deployment of ISR assets. In this paper, we present a taxonomy of terrorist incidents, identify factors related to occurrence of terrorist incidents, and provide a mathematical analysis calculating the likelihood of occurrence of terrorist incidents in three common real-life scenarios arising in peace-keeping operations

    2008-05-01

    This study was to present an odor provocation/challenge test for laryngeal hypersensitivity in a suspected odor induced dysphonic patient. The second aim was to rule out secondary gain from organic laryngeal hypersensitivity. Two steps were taken for this purpose. First, because the evaluation of hypersensitivity may be affected by the perception of odor, the study investigated laryngeal hypersensitivity during nasal and oral breathing separately to disentangle possible cognitive reactions to odors. Second, a healthy control (HC) participant was used with the identical testing protocol for nasal breathing to minimize unbiased results. The HC's response to nasal breathing of the odors showed no response to all the stimuli. The participant with possible secondary gain issues responded differently to the odors when presented nasally versus orally. Oral breathing showed less severe and less frequent laryngeal hypersensitive reactions. This suggests that laryngeal hypersensitivity was either due to the odor, cognitive information, sensory changes in olfaction leading to psychological conditioning, or for any possible secondary gain. Hence, it is difficult to indicate the precise reason (cause and effect) for the participant's laryngeal hypersensitivity; however, this study describes the first structured, controlled, repeatable, and randomized design to investigate odor induced laryngeal hypersensitivity and decipher possible secondary gain from true laryngeal hypersensitivity.

    2011-01-01

    Full Text Available This article starts from the assumption that piracy resembles terrorism in many aspects and attempts to support it through both a theoretical investigation and practical examples. The argument it makes is that Somali pirates should be prosecuted as terrorists. Moreover, it emphasizes the idea that for Somalia’s neighboring countries and not only the implementation of such an approach consists in resorting to the antiterrorist conventions already in place. Thus, for example, Kenya Navy as a piracyfi ghting agency should rely on these conventions to justify the capture and prosecution of pirates in Kenyan courts. In this respect, we emphasize the idea that only by resorting to an established international legal framework can Kenya identify the tools to counter pirates’ actions within legal limits. Moreover, this should be paralleled by efforts towards rebuilding Somalia and its institutions if long-term solutions are to be envisaged in the eradication of piracy in the Indian Ocean. In conclusion, the article looks at the concepts of piracy, terrorism and development in the Horn of Africa, suggests that piracy is a form of Terrorism and, makes a series of recommendations.

  15. Clinical and psychological aspects of adolescent involvement in extremist and terrorist activities

    Oshevsky D.S.

    2017-07-01

    Full Text Available The article deals with the clinical and psychological aspects of including minors in terrorist and extremist activities. In the historical perspective, it was traced how the views on the role of mental disorders in the genesis of such crimes changed. It is shown that terrorist and extremist activity must be viewed as a complex multi-factor phenomenon, in which socio-psychological components play a leading role. It is noted that the psychopathological process can act as a prerequisite for inclusion in such radical groups. Psychoanalytic, sociological, cognitive approaches, theories of social learning and the concept of diffuse ego-identity making attempts to explain the mechanisms of terrorist and extremist activity in minors are analyzed. The problem of insufficient study of the influence of the Internet and social networks on the formation of readiness for admission to adolescents in radical organizations is posed.

    To correlate magnetic resonance (MR) image findings with pain response by provocation discography in patients with discogenic low back pain, with an emphasis on the combination analysis of a high intensity zone (HIZ) and disc contour abnormalities. Sixty-two patients (aged 17-68 years) with axial low back pain that was likely to be disc related underwent lumbar discography (178 discs tested). The MR images were evaluated for disc degeneration, disc contour abnormalities, HIZ, and endplate abnormalities. Based on the combination of an HIZ and disc contour abnormalities, four classes were determined: (1) normal or bulging disc without HIZ; (2) normal or bulging disc with HIZ; (3) disc protrusion without HIZ; (4) disc protrusion with HIZ. These MR image findings and a new combined MR classification were analyzed in the base of concordant pain determined by discography. Disc protrusion with HIZ [sensitivity 45.5%; specificity 97.8%; positive predictive value (PPV), 87.0%] correlated significantly with concordant pain provocation (P < 0.01). A normal or bulging disc with HIZ was not associated with reproduction of pain. Disc degeneration (sensitivity 95.4%; specificity 38.8%; PPV 33.9%), disc protrusion (sensitivity 68.2%; specificity 80.6%; PPV 53.6%), and HIZ (sensitivity 56.8%; specificity 83.6%; PPV 53.2%) were not helpful in the identification of a disc with concordant pain. The proposed MR classification is useful to predict a disc with concordant pain. Disc protrusion with HIZ on MR imaging predicted positive discography in patients with discogenic low back pain.

    2016-09-01

    Lone-actor terrorist attacks have risen to the forefront of the public's consciousness in the past few years. Some of these attacks were conducted against public officials. The rise of hard-to-detect, low-tech attacks may lead to more public officials being targeted. This paper explores whether different behavioral traits are apparent within a sample of lone-actor terrorists who plotted against high-value targets (including public officials) than within a sample of lone actors who plotted against members of the public. Utilizing a unique dataset of 111 lone-actor terrorists, we test a series of hypotheses related to attack capability and operational security. The results indicate that very little differentiates those who attack high-value targets from those who attack members of the public. We conclude with a series of illustrations to theorize why this may be the case. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    This thesis shows how a government actor can use systems theory to hasten the decline of a terrorist group. Tle author assumes terrorist groups are social organizations, therefore terrorist groups come to value organizational survival over ideological or programmatic achievements. The same determinants that cause social organizations to decline will cause terrorist organizations to decline. Using systems theory to model terrorism as a system, it is possible to show how to influence these dete...

    Full Text Available Introduction: Nasal provocation testing involves an allergen-specific local reaction of the nasal mucosa to the administered allergen. Aim: To determine the most objective nasal occlusion assessment technique that could be used in nasal provocation testing. Material and methods : A total of 60 subjects, including 30 patients diagnosed with allergy to common environmental allergens and 30 healthy subjects were enrolled into the study. The method used in the study was a nasal provocation test with an allergen, with a standard dose of a control solution and an allergen (5,000 SBU/ml administered using a calibrated atomizer into both nostrils at room temperature. Early-phase nasal mucosa response in the early phase of the allergic reaction was assessed via acoustic rhinometry, optical rhinometry, nitric oxide in nasal air, and tryptase levels in the nasal lavage fluid. Results : In estimating the homogeneity of the average values, the Levene’s test was used and receiver operating characteristic curves were plotted for all the methods used for assessing the nasal provocation test with an allergen. Statistically significant results were defined for p < 0.05. Of all the objective assessment techniques, the most sensitive and characteristic ones were the optical rhinometry techniques (specificity = 1, sensitivity = 1, AUC = 1, PPV = 1, NPV = 1. Conclusions : The techniques used showed significant differences between the group of patients with allergic rhinitis and the control group. Of all the objective assessment techniques, those most sensitive and characteristic were the optical rhinometry.

Analytical measures in graph theory like degree centrality, betweenness and closeness centralities are very common and have long...... history of their successful use in revealing the importance of various members of the network. However, modeling of covert, terrorist or criminal networks through social graph dose not really provide the hierarchical structure which exist in these networks as these networks are composed of leaders...... and followers etc. In this research we analyze and predict the most likely role a particular node can adapt once a member of the network is either killed or caught.

    2007-03-01

    In 2005, a group of international decision makers developed a manual process for evaluating terrorist scenarios. That process has been implemented in the approximate reasoning Java software tool, LinguisticBelief, released in FY2007. One purpose of this report is to show the flexibility of the LinguisticBelief tool to automate a custom model developed by others. LinguisticBelief evaluates combinations of linguistic variables using an approximate reasoning rule base. Each variable is comprised of fuzzy sets, and a rule base describes the reasoning on combinations of variables fuzzy sets. Uncertainty is considered and propagated through the rule base using the belief/plausibility measure. This report documents the evaluation and rank-ordering of several example terrorist scenarios for the existing process implemented in our software. LinguisticBelief captures and propagates uncertainty and allows easy development of an expanded, more detailed evaluation, neither of which is feasible using a manual evaluation process. In conclusion, the Linguistic-Belief tool is able to (1) automate an expert-generated reasoning process for the evaluation of the risk of terrorist scenarios, including uncertainty, and (2) quickly evaluate and rank-order scenarios of concern using that process.

    Smoking is one of the varied psychological reactions to stress. This study examined the rate and changes in cigarette smoking among former Gaza and current West Bank Jewish settlers subjected to direct and indirect terrorist attacks during the Al-Aksa Intifada. The relationship with degree of religious observance and emotional distress was explored as well. In this cross-sectional study, the respondents were settlers randomly selected and interviewed by telephone (N = 706). The interview schedule included socio-demographic items, information on direct exposure to terrorist attacks (e.g. threat to life or physical integrity, personal losses, property damage) and on steady and changes in smoking habits, and a scale to measure emotional distress. In contrast with the country population, a larger percentage of settlers who smoked increased the number of cigarettes consumed with exposure to terrorism (10 and 27%, respectively). Respondents who were injured or had their home damaged reported a higher rate of smoking during the preceding year (30 and 20%, respectively). Emotional distress was related to cigarette smoking, but not in the controlled analysis. Religious observance had no effect. Direct or indirect exposure to terrorist attacks had an impact on smoking prevalence rates and on changes in smoking habits. Studies investigating reactions to traumatic events should include a detailed section on smoking while mental health interventions should address the needs of smokers.

  14. Assessing Terrorist Motivations for Attacking Critical Infrastructure

    Certain types of infrastructure--critical infrastructure (CI)--play vital roles in underpinning our economy, security and way of life. These complex and often interconnected systems have become so ubiquitous and essential to day-to-day life that they are easily taken for granted. Often it is only when the important services provided by such infrastructure are interrupted--when we lose easy access to electricity, health care, telecommunications, transportation or water, for example--that we are conscious of our great dependence on these networks and of the vulnerabilities that stem from such dependence. Unfortunately, it must be assumed that many terrorists are all too aware that CI facilities pose high-value targets that, if successfully attacked, have the potential to dramatically disrupt the normal rhythm of society, cause public fear and intimidation, and generate significant publicity. Indeed, revelations emerging at the time of this writing about Al Qaida's efforts to prepare for possible attacks on major financial facilities in New York, New Jersey, and the District of Columbia remind us just how real and immediate such threats to CI may be. Simply being aware that our nation's critical infrastructure presents terrorists with a plethora of targets, however, does little to mitigate the dangers of CI attacks. In order to prevent and preempt such terrorist acts, better understanding of the threats and vulnerabilities relating to critical infrastructure is required. The Center for Nonproliferation Studies (CNS) presents this document as both a contribution to the understanding of such threats and an initial effort at ''operationalizing'' its findings for use by analysts who work on issues of critical infrastructure protection. Specifically, this study focuses on a subsidiary aspect of CI threat assessment that has thus far remained largely unaddressed by contemporary terrorism research: the motivations and related factors that

  15. Reactivity to laboratory stress provocation predicts relapse to cocaine.

    Cocaine dependence is a chronic relapsing disorder characterized by periods of abstinence and high rates of return to drug using behavior. Elevated levels of stress have been associated with relapse to cocaine; however, the nature of this association is not well understood. The relationship between reactivity to three human laboratory provocations and relapse to cocaine was investigated. Participants were 53 cocaine-dependent individuals who were admitted for a 2-day inpatient stay during which a psychosocial provocation (i.e., the Trier Social Stress Task), a pharmacological provocation (i.e., administration of 1 microg/kg corticotrophin releasing hormone; CRH), and a drug cue exposure paradigm were completed. Adrenocortico-trophic hormone (ACTH), cortisol, heart rate, and subjective cocaine craving and stress were assessed at baseline and at multiple time points post-task. Participants' cocaine use was monitored for approximately 1 month following testing. The majority (72.3%) of participants relapsed to cocaine during the follow-up period. In response to the CRH and drug cue exposure, elevated subjective craving and stress were significant predictors of cocaine use during follow-up. In response to the Trier, attenuated neuroendocrine responses were significant predictors of cocaine use. The findings provide further evidence of the ability of laboratory paradigms to predict relapse. The observed associations between stress reactivity and subsequent cocaine use highlight the clinical importance of the findings. Predictors of relapse may vary based on the type of provocation utilized. Interventions aimed at normalizing stress response, as measured using laboratory paradigms, may prove useful in relapse prevention. Published by Elsevier Ireland Ltd.

  16. Inhaled Mannitol as a Laryngeal and Bronchial Provocation Test.

    Timely diagnosis of vocal cord dysfunction (VCD), more recently termed "inducible laryngeal obstruction," is important because VCD is often misdiagnosed as asthma, resulting in delayed diagnosis and inappropriate treatment. Visualization of paradoxical vocal cord movement on laryngoscopy is the gold standard for diagnosis, but is limited by poor test sensitivity. Provocation tests may improve the diagnosis of VCD, but the diagnostic performance of current tests is less than ideal. Alternative provocation tests are required. This pilot study demonstrates the feasibility of using inhaled mannitol for concurrent investigation of laryngeal and bronchial hyperresponsiveness. Consecutive patients with suspected VCD seen at our institution's asthma clinic underwent flexible laryngoscopy at baseline and following mannitol challenge. VCD was diagnosed on laryngoscopy based on inspiratory adduction, or >50% expiratory adduction of the vocal cords. Bronchial hyperresponsiveness after mannitol challenge was also assessed. We evaluated the interrater agreement of postmannitol laryngoscopy between respiratory specialists and laryngologists. Fourteen patients with suspected VCD in the context of asthma evaluation were included in the study. Mannitol provocation demonstrated VCD in three of the seven patients with normal baseline laryngoscopy (42.9%). Only two patients had bronchial hyperresponsiveness. There was substantial interrater agreement between respiratory specialists and laryngologists, kappa = 0.696 (95% confidence interval: 0.324-1) (P = 0.006). Inhaled mannitol can be used to induce VCD. It is well tolerated and can evaluate laryngeal and bronchial hyperresponsiveness at the same setting. Copyright © 2017 The Voice Foundation.

    Full Text Available 'This paper critiques the claim that terrorists can be profiled – that is to say that terrorists possess distinguishable attributes that can be conceivably identified by an observer. In doing so, the most prominent profiling parameters - racial, gender, age, pathological, psychological and socioeconomic – are investigated. The above approaches are found to have little to no applied value in identifying terrorists from a societal population. The dominant criticisms of these methods emphasise their crude reductionism, an absence of internal and external validity, and their lack of practical application. Current evidence indicates that the profiling of terrorists is a futile venture.'

  19. A Physicist Looks at the Terrorist Threat

    Many people fear a terrorist nuclear device, smuggled into the United States, as the one weapon that could surpass the destruction and impact of 9-11. I'll review the design of nuclear weapons, with emphasis on the kinds that can be developed by rogue nations, terrorist groups, and high-school students. Saddam, prior to the first gulf war, was developing a uranium bomb, similar to the one that destroyed Hiroshima. His calutrons (named after my university) were destroyed by the United Nations. The North Korean nuclear weapon was, like the U.S. bomb used on Nagasaki, based on plutonium. Its test released the energy equivalent of about 400 tons of TNT. Although some people have speculated that they were attempting to build a small bomb, it is far more likely that this weapon was a fizzle, with less than 1 percent of the plutonium exploded. In contrast, the energy released from burning jet fuel at the 9-11 World Trade Center attack was the equivalent of 900 tons of TNT for each plane -- over twice that of the North Korean Nuke. The damage came from the fact that gasoline delivers 10 kilocalories per gram, about 15 times the energy of an equal weight of TNT. It is this huge energy per gram that also accounts for our addiction to gasoline; per gram, high performance lithium-ion computer batteries carry only 1 percent as much energy. A dirty bomb (radiological weapon) is also unattractive to terrorists because of the threhold effect: doses less than 100 rem produce no radiation illness and will leave no dead bodies at the scene. That may be why al Qaeda instructed Jose Padilla to abandon his plans for a dirty bomb attack in Chicago, and to try a fossil fuel attack (natural gas) instead. I will argue that the biggest terrorist threat is the conventional low-tech one, such as an airplane attack on a crowded stadium using the explosive fuel that they can legally buy at the corner station.

    Although the empathy-aggression relationship has been well documented, research has yet to establish whether emotions mediate and gender moderates this relationship in athletes, under conditions of low and high provocation. In this experiment, we assigned team-sport athletes to either a high (n = 40) or a low (n = 40) empathy group, and asked them to compete in a reaction-time task against a (fictitious) opponent, under conditions of low and high provocation. Empathy reduced aggression (i.e., intensity of electrical shock administered to the opponent) at low provocation in men, and at both low and high provocation in women. Guilt mediated the effect of empathy on aggression at low provocation in men; anger did not mediate any effects of empathy on aggression. Our findings indicate that the inhibitory effect of empathy on aggression and the mediating role of guilt are moderated by provocation and gender.

    Many medical students consume alcohol in excess, which can compromise their professionalism and increase their risk of future alcohol dependency. Just one study in Japan has examined the social influences of alcohol consumption among medical students. Eighty-six per cent (n = 821) of their respondents reported experiencing some form of alcohol-related harassment since the beginning of medical school. No similar research has been conducted in the UK. A cross-sectional online questionnaire of medical students at three British medical schools. In total, 216 students answered questions regarding their experiences of alcohol-related provocation (as targets and instigators), the rate of occurrence of events and their distress following acts of provocation. An open-ended question enabled respondents to report personal experiences of alcohol-related provocation. Seventy-five per cent (n = 162) of respondents reported experiencing alcohol-related provocation during the past year, with 49.1% (n = 106) reporting instigating acts of provocation. The most prevalent experience (both for targets and instigators) was coercion to drink an entire alcoholic beverage at once as part of a game. Most acts of alcohol-related provocation generated little or no distress. Males were significantly more likely to experience some events than females. Thirty-two personal narratives of alcohol-related provocation were reported (only three reported resisting provocation). Thematic analysis identified three themes with differing power relations: ongoing 'peer-peer provocation' as a commonplace social activity, hierarchical 'peer provocation' at initiation ceremonies and 'team-mate provocation' at sports socials as bonding exercises. The tone of the narratives depended on the context in which the events described occurred. Alcohol-related provocation occurs among some UK medical students and may present professionalism issues to medical students. Medical schools may wish to integrate more teaching

    Full Text Available This study explores the explanatory value of two theories of desistance – the cessation of criminal behavior – in explaining why 27 individuals left the Islamic State in Syria and Iraq (ISIS. The article focuses specifically on jihadists that turned away from ISIS after March 2011, asking why individuals desist from ISIS and choose to leave the caliphate. A dataset of 27 narratives of desistance was analysed to answer the question to what extent desistance from ISIS by jihadists can be explained by the Laub & Sampson’s life course theory and by Altier, Thorogughood & Horgan’s model of push and pull factors. The primary pathways for desistance are coded according to the two theories. The results show that of the 27 individuals, the majority desisted from the caliphate because of their perception of the excessive use of force by ISIS and their inability to cope with the effects. A minority desisted because of their perception of alternative options outside the terrorist group or because of important life events that happened ‘at home’. Thus, the article concludes that the push and pull factors model is valid in the explanation of desistance from the Islamic State in Syria and Iraq whereas life course theory does not hold explanatory value

  8. Agent Based Modeling on Organizational Dynamics of Terrorist Network

    Directory of Open Access Journals (Sweden)

    Bo Li

    2015-01-01

    Full Text Available Modeling organizational dynamics of terrorist network is a critical issue in computational analysis of terrorism research. The first step for effective counterterrorism and strategic intervention is to investigate how the terrorists operate with the relational network and what affects the performance. In this paper, we investigate the organizational dynamics by employing a computational experimentation methodology. The hierarchical cellular network model and the organizational dynamics model are developed for modeling the hybrid relational structure and complex operational processes, respectively. To intuitively elucidate this method, the agent based modeling is used to simulate the terrorist network and test the performance in diverse scenarios. Based on the experimental results, we show how the changes of operational environments affect the development of terrorist organization in terms of its recovery and capacity to perform future tasks. The potential strategies are also discussed, which can be used to restrain the activities of terrorists.

  9. `Googling' Terrorists: Are Northern Irish Terrorists Visible on Internet Search Engines?

    Science.gov (United States)

    Reilly, P.

    In this chapter, the analysis suggests that Northern Irish terrorists are not visible on Web search engines when net users employ conventional Internet search techniques. Editors of mass media organisations traditionally have had the ability to decide whether a terrorist atrocity is `newsworthy,' controlling the `oxygen' supply that sustains all forms of terrorism. This process, also known as `gatekeeping,' is often influenced by the norms of social responsibility, or alternatively, with regard to the interests of the advertisers and corporate sponsors that sustain mass media organisations. The analysis presented in this chapter suggests that Internet search engines can also be characterised as `gatekeepers,' albeit without the ability to shape the content of Websites before it reaches net users. Instead, Internet search engines give priority retrieval to certain Websites within their directory, pointing net users towards these Websites rather than others on the Internet. Net users are more likely to click on links to the more `visible' Websites on Internet search engine directories, these sites invariably being the highest `ranked' in response to a particular search query. A number of factors including the design of the Website and the number of links to external sites determine the `visibility' of a Website on Internet search engines. The study suggests that Northern Irish terrorists and their sympathisers are unlikely to achieve a greater degree of `visibility' online than they enjoy in the conventional mass media through the perpetration of atrocities. Although these groups may have a greater degree of freedom on the Internet to publicise their ideologies, they are still likely to be speaking to the converted or members of the press. Although it is easier to locate Northern Irish terrorist organisations on Internet search engines by linking in via ideology, ideological description searches, such as `Irish Republican' and `Ulster Loyalist,' are more likely to

    Psychiatric evaluations of violent political crime were mostly performed on a case-by-case basis in a forensic environment, which made them unduly dependent on categories of presumed dangerousness and legal responsibility, rather than on a clinical definition of their mental status. In referring to such "clinical" definitions, the disorder we have in mind is not limited to the major, agitated psychotic manias or mixed states. The presence of a dominant temperament, or protracted hypomania, is enough by itself to explain an individual's engagement in a wide range of activities, not necessarily sociopathic or violent. We put forward the hypothesis that formal and transpolitical radical choices, either in favor of an illegal lifestyle or of activities involving a high level of risk, may be linked with certain mental states, especially when considering small clandestine groups showing a high level of internal ideological consensus, and a no-return attitude toward a commitment to radical choices. Available data about the psycho(patho)logical profile of terrorists are still hard to come by. The only available studies are those on identified living terrorists (judging by the trials of those who personally admitted to having been terrorists), and statistical data imply a number of documented cases belonging to the same terrorist organization. In Italy, the period often called the "years of lead [bullets]" displays an interesting viewpoint for the study of terrorist psychology, for two main reasons: first of all, it is a historically defined period (1968-1988), and second, the number of ascertained participants in terrorist activities was quite large.

  11. Forensic Seismology: constraints on terrorist bombings

    Wallace, T. C.; Koper, K. D.

    2002-05-01

    Seismology has long been used as a tool to monitor and investigate explosions, both accidental and intentional. Seismic records can be used to provide a precise chronology of events, estimate the energy release in explosions and produce constraints to test various scenarios for the explosions. Truck bombs are a popular tool of terrorists, and at least two such attacks have been recorded seismically. On August 7, 1998 a truck bomb was detonated near the US embassy in Nairobi, Kenya. The bomb seriously damaging a dozen buildings, injuring more than 4000 people and causing 220 fatalities. The explosion was recorded on a short-period seismometer located north of the blast site; the blast seismogram contained body waves, Rayleigh waves and vibrations associated with the air blast. Modeling of the body and surfaces wave allowed an estimate of the origin time of the bombing, which it turn could be used as a constraint the timing of the air blasts. The speed of the air waves from an explosion depend on the air temperature and the size, or yield, of the explosion. In an effort to fully utilize the seismic recordings from such attacks, we analyzed the seismic records from a series of controlled truck bomb explosions carried out at White Sand Missile Range in New Mexico. We developed a new set of scaling laws that relate seismic and acoustic observations directly to the explosive mass (yield). These relationships give a yield of approximately 3000 kg of TNT equivalent for the Nairobi bomb. The terrorist bombing of the Murrah Federal Building in Oklahoma City in 1995 was also recorded on seismometers. One of these records showed 2 discrete surface wavetrains separated by approximately 10 seconds. Some groups seized on the seismic recordings as evidence that there were 2 explosions, and that the US government was actually behind the bombing. However, the USGS monitored the demolition of the remainder of the Murrah Building and showed that the collapse also produced 2 surface

    Full Text Available Sixty cases of drug eruptions were observed during the period of one year. The incidence of drug eruption was 0.47% amongst all Dermatology O.P.D. attendances. Male to female ratio was 7:3. The highest number of cases were seen in the age group of 21-30 years. Fixed drug eruptions were the most frequent (58.3%, followed by urticaria and angioedema (20%. The drug sulphonamides (including co-trimoxazole accounted for the highest number of eruptions (35%. The other drugs which were responsible for the eruptions, in order of frequency, were oxyphenbutazone, ampicillin, analgin, penicillin, tetracycline, ibuprofen, paracetamol, phenylbutazone, acetaminophen and phenobarbitone. The causative drug (s were confirmed by provocation tests in 42 (70% cases.

    Vestibular and oculomotor testing is emerging as a valuable assessment in sport-related concussion (SRC). However, their usefulness for tracking recovery and guiding return-to-play decisions remains unclear. Therefore the purpose of this study was to evaluate their clinical usefulness for tracking SRC recovery. Vestibular and oculomotor assessments were used to measure symptom provocation in an acute group (n=21) concussed≤10 days, prolonged symptoms group (n=10) concussed ≥16 days (median=84 days), healthy group (n=58) no concussions in >6 months. Known-groups approach was used with three groups at three time points (initial, 2-week and 6-week follow-up). Provoked symptoms for Gaze-Stabilization (GST), Rapid Eye Horizontal (REH), Optokinetic Stimulation (OKS), Smooth-Pursuit Slow (SPS) and Fast (SPF) tests, total combined symptoms scores and near point convergence (NPC) distance were significantly greater at initial assessment in both injury groups compared to controls. Injury groups improved on the King-Devick test and combined symptom provocation scores across time. The acute group improved over time on REH and SPF tests, while the prolonged symptoms group improved on OKS. A regression model (REH, OKS, GST) was 90% accurate discriminating concussed from healthy. Vestibular and ocular motor tests give valuable insight during recovery. They can prove beneficial in concussion evaluation given the modest equipment, training and time requirements. The current study demonstrates that when combined, vestibular and oculomotor clinical tests aid in the detection of deficits following a SRC. Additionally, tests such as NPC, GST, REH, SPS, SPF OKS and KD provide valuable information to clinicians throughout the recovery process and may aid in return to play decisions. © Georg Thieme Verlag KG Stuttgart · New York.

  18. Survival of the Fittest: Why Terrorist Groups Endure

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Why do terrorist groups endure? This question is relevant to scholars and policy makers alike. In the past, this issue was not been addressed in a systematic fashion. Recent work investigates this question using data on transnational groups and finds that factors associated with the home country can influence the duration the group endures. Applying the theory of outbidding to terrorist group survival, we argue that strategic competition among groups predicts group duration. Using the Global Terrorism Database, we develop a dataset using the terrorist group as the unit of analysis to model the duration of group activity and thus include the largest sample of groups yet. Controlling for previous explanations of both group duration and terrorism, we find a robust effect for the impact that group competition has on terrorist group survival.

  1. Optimal counterterrorism and the recruitment effect of large terrorist attacks

    DEFF Research Database (Denmark)

    Jensen, Thomas

    2011-01-01

    We analyze a simple dynamic model of the interaction between terrorists and authorities. Our primary aim is to study optimal counterterrorism and its consequences when large terrorist attacks lead to a temporary increase in terrorist recruitment. First, we show that an increase in counterterrorism...... makes it more likely that terrorist cells plan small rather than large attacks and therefore may increase the probability of a successful attack. Analyzing optimal counterterrorism we see that the recruitment effect makes authorities increase the level of counterterrorism after large attacks. Therefore......, in periods following large attacks a new attack is more likely to be small compared to other periods. Finally, we analyze the long-run consequences of the recruitment effect. We show that it leads to more counterterrorism, more small attacks, and a higher sum of terrorism damage and counterterrorism costs...

    Full Text Available Terrorism is puzzling behavior for political scientists. On one hand, terrorist attacks generally hail from the politically aggrieved. On the other hand, a growing body of scholarship finds the tactic politically counterproductive. Unlike guerrilla attacks on military targets, terrorist attacks on civilian targets lower the odds of governments making  concessions. This article proposes and tests a psychological theory to account for why militant groups engage in terrorism, given the political costs of attacking civilians.

    Livesay, J R; Porter, T

    1994-08-01

    Previous studies on the psychophysiology of human emotion have repeatedly shown general and occasionally specific facial EMG (mu v) and covert cardiovascular response relationships to emotionally provocative photographs. Less clear are the relationships between psychophysiological response indices measured during the silent reading of emotionally charged versus emotionally neutral text. In this study, 12 adult subjects were presented two emotionally loaded color and black-and-white photographs and two brief newspaper articles, one emotionally charged and the other emotionally neutral in content. Each independent stimulus was presented for 1 min., preceded by a rest according to a multiple baseline-reversal design. Subjects evaluated each pictorial and textual stimulus condition according to adjective dimensions on 7-point rating scales. Mean values for corrugator supercilii EMG (mu v), upper trapezius EMG (mu v), surface temperature (degrees F), and heart rate (bpm) measured by finger photoplethysmography were measured during each rest and test period. Significant increases in the subjects' mean corrugator supercilii EMG (mu v) measures were observed during all color and black-and-white photograph presentations for both emotional and neutral content. As predicted, the subjects' mean corrugator supercilii EMG (mu v) measures increased significantly while silently reading text with an obvious unpleasant emotional tone. A significant positive relationship was observed between the subjects' mean ratings and mean corrugator EMG (mu v) difference values for the emotionally loaded color photographs.

    Dissociative identity disorder (DID) patients function as two or more identities or dissociative identity states (DIS), categorized as 'neutral identity states' (NIS) and 'traumatic identity states' (TIS). NIS inhibit access to traumatic memories thereby enabling daily life functioning. TIS have access and responses to these memories. We tested whether these DIS show different psychobiological reactions to trauma-related memory. A symptom provocation paradigm with 11 DID patients was used in a two-by-two factorial design setting. Both NIS and TIS were exposed to a neutral and a trauma-related memory script. Three psychobiological parameters were tested: subjective ratings (emotional and sensori-motor), cardiovascular responses (heart rate, blood pressure, heart rate variability) and regional cerebral blood flow as determined with H(2)(15)O positron emission tomography. Psychobiological differences were found for the different DIS. Subjective and cardiovascular reactions revealed significant main and interactions effects. Regional cerebral blood flow data revealed different neural networks to be associated with different processing of the neutral and trauma-related memory script by NIS and TIS. Patients with DID encompass at least two different DIS. These identities involve different subjective reactions, cardiovascular responses and cerebral activation patterns to a trauma-related memory script.

    Baldwin, T. E.; Ramaprasad, A,; Samsa, M. E.; Decision and Information Sciences; Univ. of Illinois at Chicago

    2008-04-02

    A primary goal of terrorism is to instill a sense of fear and vulnerability in a population and to erode its confidence in government and law enforcement agencies to protect citizens against future attacks. In recognition of its importance, the Department of Homeland Security includes public confidence as one of the principal metrics used to assess the consequences of terrorist attacks. Hence, a detailed understanding of the variations in public confidence among individuals, terrorist event types, and as a function of time is critical to developing this metric. In this exploratory study, a questionnaire was designed, tested, and administered to small groups of individuals to measure public confidence in the ability of federal, state, and local governments and their public safety agencies to prevent acts of terrorism. Data was collected from three groups before and after they watched mock television news broadcasts portraying a smallpox attack, a series of suicide bomber attacks, a refinery explosion attack, and cyber intrusions on financial institutions, resulting in identity theft. Our findings are: (a) although the aggregate confidence level is low, there are optimists and pessimists; (b) the subjects are discriminating in interpreting the nature of a terrorist attack, the time horizon, and its impact; (c) confidence recovery after a terrorist event has an incubation period; and (d) the patterns of recovery of confidence of the optimists and the pessimists are different. These findings can affect the strategy and policies to manage public confidence after a terrorist event.

  10. A Bayesian belief network of threat anticipation and terrorist motivations

    Recent events highlight the need for efficient tools for anticipating the threat posed by terrorists, whether individual or groups. Antiterrorism includes fostering awareness of potential threats, deterring aggressors, developing security measures, planning for future events, halting an event in process, and ultimately mitigating and managing the consequences of an event. To analyze such components, one must understand various aspects of threat elements like physical assets and their economic and social impacts. To this aim, we developed a three-layer Bayesian belief network (BBN) model that takes into consideration the relative threat of an attack against a particular asset (physical layer) as well as the individual psychology and motivations that would induce a person to either act alone or join a terrorist group and commit terrorist acts (social and economic layers). After researching the many possible motivations to become a terrorist, the main factors are compiled and sorted into categories such as initial and personal indicators, exclusion factors, and predictive behaviors. Assessing such threats requires combining information from disparate data sources most of which involve uncertainties. BBN combines these data in a coherent, analytically defensible, and understandable manner. The developed BBN model takes into consideration the likelihood and consequence of a threat in order to draw inferences about the risk of a terrorist attack so that mitigation efforts can be optimally deployed. The model is constructed using a network engineering process that treats the probability distributions of all the BBN nodes within the broader context of the system development process.

  11. The effects of a provocation on aggression for three types of alcohol users.

    Baldwin, J J; Randolph, D L

    1982-04-01

    Investigated the effects of a provocation on aggression for three types of alcohol users. The Alcohol Use Inventory was used to select 30 light-moderate and 30 moderate drinkers. Thirty abstainers were selected as a control group. Half of each group was assigned randomly to one of two treatments, a provocation or a no-provocation. After treatment, each S completed the Adjective Rating Form (ARF) verbal aggression scales and the Multiple Affect Adjective Checklist (MAACL). The results of this study indicated that, for both instruments, the provocation elicited significantly more feelings of hostility and verbal aggression than the no-provocation. However, there were no significant level effects, nor was there a significant interaction between level of drinking and presence of a provocation. The failure to find significant level effects was attributed to the abstainers' scores. With the abstainer category excluded from the analysis, additional findings resulted in significant level effects for the MAACL hostility scales, but not for the ARF verbal aggression scales. It was recommended that future studies investigate risk factors of abstinence and eliminate the abstainer category as a control.

    Full Text Available Recent actions by French military forces in Niger and the global prominence of terrorist groups such as Al Shabaab and Boko Haram, have highlighted the growing counter terrorist focus on the countries of Sub Saharan Africa. Additionally in a post Bin Laden world and with the immanent withdrawal of coalition combat troops from Afghanistan, there is the possibility of Africa as a continent becoming the new front in the Global War on Terror ('Mben' et al., 2013. However, it is a mistake to assume that Africa’s story is uniformly one of violence and death. Vibrant cultures and a rugged entrepreneurial spirit have combined with a robust Internet backbone, to create the embryonic emergence of high tech hotspots across Africa. With rising IT literacy levels, more and more Africans are becoming connected to the information super highway on a daily basis (Graham, 2010. A tiny minority of these Africans are terrorists.

  14. Assessing Terrorist Motivations for Attacking Critical "Chemical" Infrastructure

    Energy Technology Data Exchange (ETDEWEB)

    Ackerman, G; Bale, J; Moran, K

    2004-12-14

    Certain types of infrastructure--critical infrastructure (CI)--play vital roles in underpinning our economy, security, and way of life. One particular type of CI--that relating to chemicals--constitutes both an important element of our nation's infrastructure and a particularly attractive set of potential targets. This is primarily because of the large quantities of toxic industrial chemicals (TICs) it employs in various operations and because of the essential economic functions it serves. This study attempts to minimize some of the ambiguities that presently impede chemical infrastructure threat assessments by providing new insight into the key motivational factors that affect terrorist organizations propensity to attack chemical facilities. Prepared as a companion piece to the Center for Nonproliferation Studies August 2004 study--''Assessing Terrorist Motivations for Attacking Critical Infrastructure''--it investigates three overarching research questions: (1) why do terrorists choose to attack chemical-related infrastructure over other targets; (2) what specific factors influence their target selection decisions concerning chemical facilities; and (3) which, if any, types of groups are most inclined to attack chemical infrastructure targets? The study involved a multi-pronged research design, which made use of four discrete investigative techniques to answer the above questions as comprehensively as possible. These include: (1) a review of terrorism and threat assessment literature to glean expert consensus regarding terrorist interest in targeting chemical facilities; (2) the preparation of case studies to help identify internal group factors and contextual influences that have played a significant role in leading some terrorist groups to attack chemical facilities; (3) an examination of data from the Critical Infrastructure Terrorist Incident Catalog (CrITIC) to further illuminate the nature of terrorist attacks against chemical

    2013-09-01

    Full Text Available This paper inquires into whether the right to a fair trial can be restricted with regard to alleged terrorists within the framework of the ‘war on terror’. After briefly identifying the relevant sources of this right and its content, possible restrictions are analysed. The paper elaborates, in particular, on international humanitarian law, such as the Third and Fourth Geneva Convention, and international human rights law, such as the International Covenant on Civil and Political Rights and the American Declaration of the Rights and Duties of Man. It further deals with US constitutional law. We conclude that the right to a fair trial fully applies to alleged terrorists irrespective of the context of their detention (armed conflict or peace or the qualification of these terrorists (de facto or unlawful combatants and thus amounts to a general principle of transnational criminal law.

    The acute heart failure (AHF) Syndromes International Working Group proposed that dyspnea be assessed under standardized, incrementally provocative maneuvers and called for studies to assess the feasibility of this approach. We sought to assess the feasibility and statistical characteristics of a novel provocative dyspnea severity score (pDS) versus the traditional dyspnea visual analog scale (DVAS) in an AHF trial. At enrollment, 24, 48 and 72hours, 230 ROSE-AHF patients completed a DVAS. Dyspnea was then assessed with 5-point Likert dyspnea scales administered during 4 stages (A: upright-with O2, B: upright-without O2, C: supine-without O2 and D: exercise-without O2). Patients with moderate or less dyspnea were eligible for the next stage. At enrollment, oxygen withdrawal and supine provocation were highly feasible (≥97%), provoking more severe dyspnea (≥1 Likert point) in 24% and 42% of eligible patients, respectively. Exercise provocation had low feasibility with 38% of eligible patients unable to exercise due to factors other than dyspnea. A pDS was constructed from Likert scales during the 3 feasible assessment conditions (A-C). Relative to DVAS, the distribution of the pDS was more skewed with a high "ceiling effect" at enrollment (23%) limiting sensitivity to change. Change in pDS was not related to decongestion or 60-day outcomes. Although oxygen withdrawal and supine provocation are feasible and elicit more severe dyspnea, exercise provocation had unacceptable feasibility in this AHF cohort. The statistical characteristics of a pDS based on feasible provocation measures do not support its potential as a robust dyspnea assessment tool in AHF. Copyright © 2015 Elsevier Inc.

  17. Provocation of symmetry/ordering symptoms in Anorexia nervosa: a functional neuroimaging study.

    Directory of Open Access Journals (Sweden)

    Masashi Suda

    Full Text Available Anorexia nervosa (AN, obsessive-compulsive disorder (OCD, and obsessive-compulsive personality disorder (OCPD are often co-morbid; however, the aetiology of such co-morbidity has not been well investigated. This study examined brain activation in women with AN and in healthy control (HC women during the provocation of symmetry/ordering-related anxiety. During provocation, patients with AN showed more anxiety compared to HCs, which was correlated with the severity of symmetry/ordering symptoms. Activation in the right parietal lobe and right prefrontal cortex (rPFC in response to provocation was reduced in the AN group compared with the HC group. The reduced right parietal activation observed in the AN group is consistent with parietal lobe involvement in visuospatial cognition and with studies of OCD reporting an association between structural abnormalities in this region and the severity of 'ordering' symptoms. Reduced rPFC activation in response to symmetry/ordering provocation has similarities with some, but not all, data collected from patients with AN who were exposed to images of food and bodies. Furthermore, the combination of data from the AN and HC groups showed that rPFC activation during symptom provocation was inversely correlated with the severity of symmetry/ordering symptoms. These data suggest that individuals with AN have a diminished ability to cognitively deal with illness-associated symptoms of provocation. Furthermore, our data also suggest that symptom provocation can progressively overload attempts by the rPFC to exert cognitive control. These findings are discussed in the context of the current neurobiological models of AN.

    The classification of pelvic girdle pain can only be reached after lumbar causes have been excluded by a clinical examination. During clinical examination, the posterior pelvic pain provocation test is a well-established method for verifying pelvic girdle pain. However, a criticism of pelvic pain provocation tests is that they may have an effect on lumbar structures, thus yielding false-positive results. The posterior pelvic pain provocation test was performed with four groups of patients: patients with computed tomography-verified disc herniations (1) on the waiting list for surgery (14 women; 9 men); (2) 6 weeks after disc surgery (18 women, 12 men); (3) pregnant women seeking care for pelvic girdle pain (n = 25); and (4) women with persistent pelvic girdle pain after delivery (n = 32). The sensitivity of the posterior pelvic pain provocation test was 0.88 and the specificity was 0.89. The positive predictive value was 0.89 and the negative predictive value was 0.87. Analysis of only women showed similar results. In our study, the posterior pelvic pain provocation test was negative in patients with a well-defined lumbar diagnosis of lumbar disc herniation, both before and after disc surgery. Our results are an important step toward the more accurate classification of lumbopelvic pain.

    Full Text Available Fixed drug eruption (FDE is recurrent lesions that upon repeated uptake of causative drug, always appears at the same skin and mucosal site. Determination of causal relationship in drug allergy is very important. In this case report, cases of doxycycline-induced FDE was reported. The subject of the research was a 29-year-old male, referred by dermatologist, with history of reccurent FDE. Physical examination revealed an oval well demarcated patch hyperpigmentation. Patch test was perfomed on previous involved and uninvolved site. The result of the patch test was irrelevant. Retesting patch test gave similar result. Systemic provocation test or drug provocation test (DPT  with doxcycline were done with suspected drug under ambulatory survelance and gave positive result. In this case, the DPT succeeded to identify doxycycline as the causal agent of FDE. The work-up of a suspected drug hypersensitivity includes a detailed clinical history, physical examination, skin tests, and provocation tests. The DPT is recommended to confirm drug’s hypersensitivity reactions. Systemic provocation test is considered as the gold standard for diagnosing FDE.

  1. COMMUNICATIVE PROVOCATION AS A STRATEGY OF DESTRUCTIVE BEHAVIOUR IN EVERY-DAY CONFLICT

    Directory of Open Access Journals (Sweden)

    Volkova Olga Sergeevna

    2014-12-01

    Full Text Available The article is concentrated on the issue of systematization and classification of strategies and tactics of individual's verbal behavior in a number of typical situations associated with disharmonious communication. Its scientific originality is defined by the necessity to present the provocation phenomenon as a category of communicative linguistics and linguistic pragmatics. The use of discourse analysis and descriptive pragmatic interpretation of real communication forms have enabled the revelation of various patterns of destructive verbal behavior that could provoke a communicative conflict. Communicative provocation is described as a strategy of destructive behavior aimed at dragging a communication partner into a conflict interaction or creating conditions for its occurrence. The provocation strategy is implemented in disharmonious interactions by means of individual or complex communication tactics including not only the aggressive ones: indignation, reproach, deliberate false informing, exaggerated demonstration of emotions, but also such tolerant tactics as praise, advice, apology, assurances, admiration, persuasion, etc. Two forms of communicative provocation are represented in the article. A direct provocation presupposes personal involvement of a provocateur in the conflict interaction while an indirect one allows its initiator stay aside from the open confrontation. In the latter case the provocateur stimulates and demonstrates the parties' conflict of interests, which leads to the communication harmony disruption.

    Full Text Available Women and their religiosity are questioned along with the proliferation of conflict, violence, and religion-based riots which allegedly involving ‘husband’  suspected  terrorists. This article discusses the religiosity of the wives, the adjustment of wives of suspected terrorists against psychological and social burden, and the patterns of marital relations of terrorist suspects in Pekalongan-Central Java. The result of this phenomenological study revealed that the religiosity of terrorist-suspects’ wives are more dominant is exclusive patterned- if it is compared to moderate or inclusive ones. In terms of adjustment, the wives are just accept the fate and tend to be indifferent to the activities of their husbands. The wives also nullifying the public’s negative perception and judgment, but some are closed to the social interaction. While the pattern of relationships that were frequently built tent to be more owner property and head-complement in characteristics. Wives are positioned as husband’s complement for all activities in the fields of social, religious and political.

    Considerable research has shown that alcohol consumption can increase aggression and produce extremes in other social behaviors. Although most theories posit that such effects are caused by pharmacological impairment of cognitive processes, recent research indicates that exposure to alcohol-related constructs, in the absence of consumption, can produce similar effects. Here we tested the hypothesis that alcohol priming is most likely to affect aggression in the context of ambiguous provocation. Experiment 1 showed that exposure to alcohol primes increased aggressive retaliation but only when an initial provocation was ambiguous; unambiguous provocation elicited highly aggressive responses regardless of prime exposure. Experiment 2 showed that alcohol prime exposure effects are relatively short-lived and that perceptions of the provocateur's hostility mediated effects of prime exposure on aggression. These findings suggest modification and extension of existing models of alcohol-induced aggression. © 2014 by the Society for Personality and Social Psychology, Inc.

    2016-01-01

    Full Text Available Allergic rhinitis is a major chronic respiratory disease and an immunoneuronal disorder. We aimed at providing further knowledge on the function of the neural system in nasal allergic reaction. Here, a method to assess simultaneously the nasal airflow resistance and the underlying function of autonomic nervous system (ANS is presented and used during the nasal provocation of allergic and nonallergic subjects. Continuous nasal airflow resistance and spectral heart rate variability parameters show in detail the timing and intensity differences in subjects’ reactions. After the provocation, the nasal airflow resistance of allergic subjects showed a positive trend, whereas LF/HF (Low Frequency/High Frequency ratio and LF power showed a negative trend. This could imply a gradual sympathetic withdrawal in allergic subjects after the allergen provocation. The groups differed significantly by these physiological descriptors. The proposed method opens entirely new opportunities to research accurately concomitant changes in nasal breathing function and ANS.

    Rogers, M Brooke; Loewenthal, Kate M; Lewis, Christopher Alan; Amlôt, Richard; Cinnirella, Marco; Ansari, Humayan

    2007-06-01

    This paper examines the social-psychological factors often implicated in discussions of terrorist violence/martyrdom, with a particular focus on the role of religion. We offer a brief description of the psychological theories underpinning terrorist research before focusing on social-psychological factors. The roles of psychopathology, irrationality and grievance/threat are examined, followed by empirical research on the beliefs which have been associated with the perpetration and support of terrorist violence, and the social factors which foster those beliefs, including social identity, socially carried interpretations, group leadership and individual differences. Although religion is not a single, simple causal factor in terrorist violence, religious elements often feature strongly in the belief systems associated with terrorist violence, and can also feature in other important fostering factors for terrorist violence, such as the use of rhetoric. Finally, the status of lay explanations of terrorist violence, focusing on the role of religious fundamentalism is examined.

  14. Estimates of radiological risk from a terrorist attack using plutonium.

    Durante, Marco; Manti, Lorenzo

    2002-06-01

    The possible use of radioactivity dispersal devices by terrorist groups has been recently reported in the news. In this paper, we discuss the threat of terrorist attacks by plutonium, with particular attention to the dispersal of plutonium by explosion or fire. Doses resulting from inhalation of radioactive aerosol induced by a plutonium explosion or fire are simulated using a Gaussian plume model (the HOTSPOT code) for different meteorological conditions. Ground contamination and resuspension of dust are also considered in the simulations. Our simulations suggest that acute effects from a plutonium dispersal attack are very unlikely. For late stochastic effects, the explosion poses a greater hazard than fire. However, even in the worst-case scenario, the dispersed plutonium would cause relatively few excess cancers (around 80 in a city of 2 million inhabitants) after many years from the explosion, and these excess cancers would remain undetected against the background of cancer fatalities.

    The November 26-29, 2008, terrorist attacks on Mumbai were unique in its international media attention, multiple strategies of attack, and the disproportionate national fear they triggered. Everyone was a target: random members of the general population, iconic targets, and foreigners alike were under attack by the terrorists. A retrospective, descriptive study of the distribution of terror victims to various city hospitals, critical radius, surge capacity, and the nature of specialized medical interventions was gathered through police, legal reports, and interviews with key informants. Among the 172 killed and 304 injured people, about four-fifths were men (average age, 33 years) and 12% were foreign nationals. The case-fatality ratio for this event was 2.75:1, and the mortality rate among those who were critically injured was 12%. A total of 38.5% of patients arriving at the hospitals required major surgical intervention. Emergency surgical operations were mainly orthopedic (external fixation for compound fractures) and general surgical interventions (abdominal explorations for penetrating bullet/shrapnel injuries). The use of heavy-duty automatic weapons, explosives, hostages, and arson in these terrorist attacks alerts us to new challenges to medical counterterrorism response. The need for building central medical control for a coordinated response and for strengthening public hospital capacity are lessons learned for future attacks. These particular terrorist attacks had global consequences, in terms of increased security checks and alerts for and fears of further similar "Mumbai-style" attacks. The resilience of the citizens of Mumbai is a critical measure of the long-term effects of terror attacks.

    Baur, X; Fruhmann, G; von Liebe, V

    1978-12-15

    87 patients with bronchial asthma underwent skin test, RAST and measurment of airway resistance before and after inhalation of control solution as well as at least 10 times after each of one to four bronchial provocations (making up a total of 171 tests) with extracts of house dust, house dust mite, animal dander, mould spores and pollen in increasing concentrations. An actual clinical significance of the skin test reactions was found in 60% of all cases and of the RAST results in 66% of all cases. The overall agreement between skin test results and RAST results was 61%. The correlations between the different tests depended on the degree of hypersensitivity, on the tested allergen and on whether the results of skin test and RAST, respectively, were positive or negative. There existed a good correlation between the results of all three test methods and case history only for pollen allergens and animal dander. Noticeably often negative RAST results with house dust and mould spores, as well as positive skin tests with house dust mite and mould spores could not be confirmed by the provocation test. Important indications for a bronchial provocation test in asthmatics are doubtful case history, doubtful skin test or RAST results with the problem-allergens house dust, house dust mite and mould spores; the bronchial provocation test is especially commendable when drastic or cumbersome therapeutic measures (immunotherapy, change of home, change of job) are to follow or if late asthmatic reactions are expected.

    Full Text Available Increasingly, research is turning to the ways in which social context impacts decision making and feedback processing in adolescents. The current study recorded electroencephalography to examine the trajectory of development across adolescence, with a focus on how social context impacts cognition and behaviour. To that end, younger (10–12 years and older (14–16 years adolescents played a modified Taylor Aggression Paradigm against two virtual opponents: a low-provoker and a high-provoker. During the task's decision phase (where participants select punishment for their opponent, we examined two event-related potentials: the N2 and the late positive potential (LPP. During the outcome phase (where participants experience win or loss feedback, we measured the feedback related negativity (FRN. Although N2 amplitudes did not vary with provocation, LPP amplitudes were enhanced under high provocation for the younger group, suggesting that emotional reactivity during the decision phase was heightened for early adolescents. During the outcome phase, the FRN was reduced following win outcomes under high provocation for both groups, suggesting that a highly provocative social opponent may influence the reward response. Collectively, the data argue that social context is an important factor modulating neural responses in adolescent behavioural and brain development.

    2016-05-01

    The role of cyber forensics in criminal investigations has greatly increased in recent years due to the wealth of data that is collected and available to investigators. Physical forensics has also experienced a data volume and fidelity revolution due to advances in methods for DNA and trace evidence analysis. Key to extracting insight is the ability to correlate across multi-modal data, which depends critically on identifying a touch-point connecting the separate data streams. Separate data sources may be connected because they refer to the same individual, entity or event. In this paper we present a data source classification system tailored to facilitate the investigation of potential terrorist activity. This taxonomy is structured to illuminate the defining characteristics of a particular terrorist effort and designed to guide reporting to decision makers that is complete, concise, and evidence-based. The classification system has been validated and empirically utilized in the forensic analysis of a simulated terrorist activity. Next-generation analysts can use this schema to label and correlate across existing data streams, assess which critical information may be missing from the data, and identify options for collecting additional data streams to fill information gaps.

    Children with congenital malformations, mental retardation, and complex early medical history frequently have feeding problems. Although tube feeding is effective in providing the necessary energy and nutrients, it decreases the child's motivation to eat and may lead to oral aversion. In this study, we sought to confirm our previous results, showing that a multidisciplinary clinical hunger provocation program may lead to quick resumption of oral feeding. In a crossover study, 22 children of 9 to 24 months of age who were fully dependent on tube feeding were randomly assigned to one of two groups: group A, intervention group (2-week multidisciplinary clinical hunger provocation program); and group B, control group (4-week outpatient treatment by the same multidisciplinary team). Patients failing one treatment were reassigned to the other treatment group. Primary outcome measures were at least 75% orally fed at the conclusion of the intervention and fully orally fed and gaining weight 6 months after the intervention. In group A, 9/11 patients were successfully weaned from tube feeding (2 failures: 1 developed ulcerative colitis, 1 drop-out). In group B, only 1 patient was weaned successfully; 10/11 were reassigned to the clinical hunger provocation program, all being weaned successfully. Six months after the intervention, 1 patient had to resume tube feeding. In total, in the control group, 1/11 (9%) was weaned successfully as compared with 18/21 (86%) in the hunger provocation group (P hunger provocation is an effective short-term intervention for weaning young children from tube feeding.

    Skin testing has a limited role in the diagnosis of non-immediate beta-lactam hypersensitivity in children. The aim of this study was to report the results of oral provocation tests performed without skin tests in children with non-immediate mild cutaneous reactions without systemic symptoms caused by beta-lactam antibiotics. Oral provocation tests with suspected antibiotics were performed to patients with non-immediate mild cutaneous reactions without systemic symptoms caused by beta-lactam antibiotics. Skin tests were not performed before provocation tests. A total of five doses were administered with half-an-hour intervals in increasing doses. Provocation was continued for 5 days. A total of 119 patients with a median age of 4.3 (IQR: 2-7.5) years, of whom 58% were males, were included in the study. Amoxicillin-clavulanic acid was the most frequently responsible agent in 87 (73.1%) patients, and most common type of rash was maculopapular in 74 (62.2%) patients. Four patients (3.4%) had an urticarial reaction during the provocation test. We did not experience any severe reactions during oral provocation test without previous skin tests performed to children with non-immediate mild cutaneous reactions without systemic symptoms. Omitting skin tests before oral provocation test in this group of children can help decreasing the burden of allergy clinics and alleviating the discomfort of children. © 2015 John Wiley & Sons A/S.

    Pécoud, A; Zuber, P; Kolly, M

    1987-01-01

    Levocabastine is a new selective H1 receptor antagonist. The effect of the drug administered locally was compared to placebo in a quantified nasal and conjunctival provocation test with allergens performed in patients allergic to grass pollen. In the nasal provocation test, levocabastine was able to increase the 'reaction threshold' (dose of allergen necessary to trigger allergic symptoms) in 9 out of 12 patients; the drug inhibited rhinorrhea and sneezing, but not nasal obstruction. In the conjunctival provocation test, the 'reaction threshold' clearly increased in 10 out of 11 patients. The local administration of levocabastine might be useful in allergic rhinitis and conjunctivitis.

  20. Psychiatric aspects of terrorist violence: Northern Ireland 1969-1987.

    Curran, P S

    1988-10-01

    For 18 years, Northern Ireland has suffered a changing pattern of civil disorder. Early years were marked by widespread sectarian rioting, shootings, and bombings, which heightened community tension and caused much social and commercial disruption. However, in recent years, terrorist organisations have been more selective in their acts of violence. There are methodological difficulties in assessing the psychological impact of civil disorder and terrorism. But, as well as can be judged from community surveys, hospital admissions and referral data, psychotropic drug usage, suicide and attempted suicide rates, and from assessment of the actual victims of violence, society has not 'broken down' nor has the impact been judged considerable. Possible explanations are discussed.

  1. [The effects of media violence on aggression: focus on the role of anger evoked by provocation].

    Science.gov (United States)

    Yukawa, S; Endo, K; Yoshida, F

    2001-04-01

    This study investigated the effects of anger evoked by earlier provocation on cognition, emotion, and aggressive behavior after being exposed to media violence. Sixty male undergraduates participated in the experiment. Before viewing one of three videos (either highly violent, violent with high entertainment, or nonviolent), half of the subjects were provoked by a confederate posing as another subject. Subjects' heart rates and eyeblink rates were recorded while viewing the video. After viewing the video, subjects described their thoughts that occurred while watching the video and rated their affective reactions toward the video. Finally, subjects' aggressive behavior toward the confederate was measured. Results of covariance structure analysis suggested that (a) anger evoked by provocation and high level of violence in videos additively elicited negative cognition and affect, which further facilitated aggressive behavior, and (b) high level of entertainment in videos elicited positive cognition and affect, which alleviated negative cognition and affect.

  2. Experimental panic provocation in healthy man—a translational role in anti-panic drug development?

    Science.gov (United States)

    Kellner, Michael

    2011-01-01

    Experimental neurochemical provocation of panic attacks in susceptible human subjects has considerably expanded our knowledge of the pathophysiology and psychopharmacology of panic disorder. Some panicogens also elicit short-lived panic-like states in healthy man. This offers the opportunity to assess the anti-panic action of drugs in proof-of-concept studies. However, from current data it is still unclear whether experimental panic in healthy man is a valid translational model. Most such studies in healthy volunteers have been performed using a cholecystokinin tetrapeptide (CCK-4) challenge. While CCK-4 panic was blocked by alprazolam pretreatment, escitalopram showed negative results in healthy man. Preliminary findings on novel investigational drugs and a few problematic results will be reviewed. Small sample sizes in many panic provocation studies, lack of dose-response aspects, and still-insufficient knowledge about the biological underpinning of experimental and spontaneous panic limit the interpretation of existing findings and should inspire further research.

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

    Dumping syndrome is a well-known complication after upper gastrointestinal (GI) surgery. There are scarce data in the literature about the incidence of dumping after bariatric operations but, certainly no relation between this syndrome and laparoscopic sleeve gastrectomy (LSG) has been attempted. We conducted a prospective clinical study in order to evaluate the potential presence, incidence and severity of Dumping syndrome after LSG. Thirty one non-diabetic morbidly obese patients (eight male, 23 female) eligible for LSG were evaluated. Median age was 38 (22-58 years) and mean body mass index (BMI) was 45.55 (± 5.37). The diagnosis of dumping syndrome was based on clinical provocation of signs and symptoms using an oral glucose challenge before and 6 weeks after the operation. The Sigstad's dumping score was estimated in order to separate dumpers from non-dumpers, and the Arts questionnaire was completed to distinguish between early and late dumping. Moreover, blood glucose levels during the oral glucose challenge were measured. No patient had symptoms of dumping after provocation preoperatively, whereas after LSG 9 patients (29%) experienced definite dumping and other 5 patients (16%) symptoms suggestive of dumping syndrome. Arts' questionnaire demonstrated that dumping occurrence after LSG was associated with early symptoms. Late hypoglycaemia occurred in one patient. A significant proportion of patients after LSG experienced dumping syndrome upon provocation. It seems that LSG should no longer be considered as a pure restrictive procedure, and it might be an option for heavy sweeters by changing their food tolerance patterns.

    Anorexia nervosa (AN) is perhaps the most lethal mental disorder, in part due to starvation-related health problems, but especially because of high suicide rates. One potential reason for high suicide rates in AN may be that those affected face pain and provocation on many fronts, which may in turn reduce their fear of pain and thereby increase risk for death by suicide. The purpose of the following studies was to explore whether repetitive exposure to painful and destructive behaviors such as vomiting, laxative use, and non-suicidal self-injury (NSSI) was a mechanism that linked AN-binge-purging (ANBP) subtype, as opposed to AN-restricting subtype (ANR), to extreme suicidal behavior. Study 1 utilized a sample of 787 individuals diagnosed with one or the other subtype of AN, and structural equation modeling results supported provocative behaviors as a mechanism linking ANBP to suicidal behavior. A second, unexpected mechanism emerged linking ANR to suicidal behavior via restricting. Study 2, which used a sample of 249 AN patients, replicated these findings, including the second mechanism linking ANR to suicide attempts. Two potential routes to suicidal behavior in AN appear to have been identified: one route through repetitive experience with provocative behaviors for ANBP, and a second for exposure to pain through the starvation of restricting in ANR.

    Terrorism and disasters receive massive media attention, and victims are often approached by reporters. Not much is known about how terror and disaster victims perceive the contact with media and whether such experiences influence mental health. In this study, we describe how positive and negative experiences with media relate to posttraumatic stress (PTS) reactions among survivors of the 2011 Utøya Island terrorist attack in Norway. Face-to-face interviews were conducted with 285 survivors (47.0% female and 53.0% male) 14-15 months after the terrorist attack. Most survivors were approached by reporters (94%), and participated in media interviews (88%). The majority of survivors evaluated their media contact and participation as positive, and media participation was unrelated to PTS reactions. Survivors who found media participation distressing had more PTS reactions (quite distressing: B = 0.440, extremely distressing: B = 0.611, p = .004 in adjusted model). Perceiving media participation as distressing was slightly associated with lower levels of social support (r = -.16, p = .013), and regretting media participation was slightly associated with feeling let down (r = .18, p = .004). Reporters should take care when interviewing victims, and clinicians should be aware of media exposure as a potential additional strain on victims.

    2016-01-01

    From the framework of Terror Management Theory, the objective of the present research is to analyze the effect of mortality salience (MS) on the minimization of Muslim terrorists’ secondary emotions (MSE, which can be understood as a particular kind of dehumanization), as a function of political orientation. An experimental design was used, in which the participants (university students, N= 293) were randomly assigned to a control or experimental group, their political orientation was taken note of, and they were asked to attribute emotions to Muslim terrorists. In accordance with the hypotheses, the results indicate that, among those supporting tenets of the political left, MS originates less minimization of secondary emotions of the terrorists (MSE). However, among people who stand on the right, MS inspires greater MSE (that is, a lower attribution of these emotions). These results support the thesis that the effects of MS are not to be found exclusively in conservative people, and that they do not necessarily imply a conservative shift, but constitute a polarization in previous ideological tendencies or cultural worldview.

    To examine whether the ease of disease provocation by UV-A and/or UV-B radiation correlates with clinical features of polymorphic light eruption (PLE), including those indicative of disease severity. Intervention study. One hundred forty-three patients with PLE. Provocation testing with broadband UV-A and UV-B lamps. Additionally, a range of clinical characteristics of the disorder, including a 5-item PLE severity score, was assessed by questionnaire. Percentage of PLE rash induction by UV-A and UV-B provocation, differences between the skin types, and correlation between the results of provocation and a range of clinical characteristics of the disorder, including a 5-item PLE severity score. Rash provocation was seen in 78.3% of patients after UV-A and in 46.7% after UV-B exposure. Neither UV-A nor UV-B provocation showed a significant association with the total 5-item severity score. The UV-B reactivity was associated with a high score on the severity item "number of months affected per year" (P = .04), whereas UV-A responsiveness showed a tendency for association with facial involvement (P = .06). The objective assessment of UV-A or UV-B susceptibility in this large group of patients showed no significant relationship with clinical disease severity.

    Terrorism is a huge public hazard of the international community. Alliances of terrorist organizations may cause more serious threat to national security and world peace. Understanding alliances between global terrorist organizations will facilitate more effective anti-terrorism collaboration between governments. Based on publicly available data, this study constructed a alliance network between terrorist organizations and analyzed the alliance relationships with link prediction. We proposed a novel index based on optimal weighted fusion of six similarity indices, in which the optimal weight is calculated by genetic algorithm. Our experimental results showed that this algorithm could achieve better results on the networks than other algorithms. Using this method, we successfully digged out 21 real terrorist organizations alliance from current data. Our experiment shows that this approach used for terrorist organizations alliance mining is effective and this study is expected to benefit the form of a more powerful anti-terrorism strategy.

    Positive identification of human remains is one of the most important tasks in mass disaster investigations. Religious and jurisdictional demands in Israel, require the identification process to be completed in the shortest possible time. In the 18 suicidal terrorist bombings that took place in Israel between the years 1993-1996, 127 victims and 19 perpetrators were killed, and their severely fragmented bodies were identified within 24 h. The efficient completion of the identification endeavor was enabled by the implementation of a variety of techniques and the close collaboration in the investigation between the different emergency and forensic agencies. This paper presents the mass disaster identification policy and techniques currently used in Israel. The importance of an interdisciplinary approach for the identification of extremely fragmented human remains from mass disasters and the creation of a central data bank of fingerprints and genetic markers is emphasized.

    The Terrorist Radicalization Assessment Protocol (TRAP-18) is a structured professional judgment instrument for the assessment of individuals who present a concern for lone-actor terrorism. It consists of eight proximal warning behaviors and 10 distal characteristics. Previous research has demonstrated its interrater reliability and some concurrent and postdictive validity. In this article, TRAP-18 is retrospectively applied to the case of US Army psychiatrist and jihadist Malik Nidal Hasan, who committed a mass murder at Fort Hood, Texas in 2009. The strengths and limitations of TRAP-18 as a structured professional judgment instrument for mental health clinicians are discussed, and clinical risk management suggestions are made.

    2017-03-01

    Hatred of terrorists is an obstacle to the implementation of effective counterterrorism policies-it invites indiscriminate retaliation, whereas many of the greatest successes in counterterrorism have come from understanding terrorists' personal and political motivations. Drawing from psychological research, traditional prejudice reduction strategies are generally not well suited to the task of reducing hatred of terrorists. Instead, in 2 studies, we explored education's potential ability to reduce extreme negative attitudes toward terrorists. Study 1 compared students in a college course on terrorism (treatment) with wait-listed students, measuring prosocial attitudes toward a hypothetical terrorist. Initially, all students reported extremely negative attitudes; however, at the end of the semester, treatment students' attitudes were significantly improved. Study 2 replicated the effect within a sample of treatment and control classes drawn from universities across the United States. The present work was part of an ongoing research project, focusing on foreign policy and the perceived threat of terrorism; thus classes did not explicitly aim to reduce prejudice, making the effect of treatment somewhat surprising. One possibility is that learning about terrorists "crowds out" the initial pejorative associations-that is, the label terrorism may ultimately call more information to mind, diluting its initial negative associative links. Alternatively, students may learn to challenge how the label terrorist is being applied. In either case, learning about terrorism can decrease the extreme negative reactions it evokes, which is desirable if one wishes to implement effective counterterrorism policies.

    Full Text Available Events that took place on 9/11, when symbols of American nation were destroyed by hijacked civilian airplanes, raised the issue of the effectiveness of the currently existing legal framework which regulates terrorist activities. Prior to that event, dealing with terrorist activities was mostly regulated by conventions, many of which were ratified by no more than couple of states. However, it became questionable whether these instruments are sufficient to fight terrorists who are not only immune to a threat of sanctions, but are even ready to sacrifice their lives. After the attacks took place, the United States launched against Afghanistan an armed action, ending up in a more than a decade long occupation, holding Taliban regime responsible for the attacks undertaken by Al-Qaida. The United States response to the 9/11 raised an important question: what is the legal response to terrorist attacks? This article explores the current legal framework of the use of force in response to terrorist attacks, especially with regard to distinguishing terrorist acts which are attributable to a certain state, from those which are undertaken by a terrorist group, not associated with any particular state.

This article also examines whether lone-actor terrorists differ based on their ideologies or network connectivity. The analysis leads to seven conclusions. There was no uniform profile identified. In the time leading up to most lone-actor terrorist events, other people generally knew about the offender's grievance, extremist ideology, views, and/or intent to engage in violence. A wide range of activities and experiences preceded lone actors' plots or events. Many but not all lone-actor terrorists were socially isolated. Lone-actor terrorists regularly engaged in a detectable and observable range of activities with a wider pressure group, social movement, or terrorist organization. Lone-actor terrorist events were rarely sudden and impulsive. There were distinguishable behavioral differences between subgroups.

    Civilian mass casualty incidents may occur infrequently and suddenly, and are caused by accidents, natural disasters or human terrorist incidents. Most reports deal with trauma centre management in large cities, and data from small local hospitals are scarce. A rural hospital response to a mass casualty incident caused by a terrorist shooting spree was evaluated. An observational study was undertaken to evaluate the triage, diagnosis and management of all casualties received from the Utøya youth camp in Norway on 22 July 2011 by a local hospital, using data from the hospital's electronic records. Descriptive data are presented for patient demographics, injuries and patient flow. The shooting on Utøya youth camp left 69 people dead and 60 wounded. A rural hospital (Ringerike Hospital) triaged 35 patients, of whom 18 were admitted. During the main surge, the hospital triaged and treated 22 patients within 1 h, of whom 13 fulfilled the criteria for activating the hospital trauma team, including five with critical injuries (defined as an Injury Severity Score above 15). Ten computed tomography scans, two focused assessment with sonography for trauma (FAST) scans and 25 conventional X-rays were performed. During the first 24 h, ten surgical procedures were performed and four chest drains inserted. No patient died. Critical deviation from the major incident plan was needed, and future need for revision is deemed necessary based on the experience. Communication systems and the organization of radiological services proved to be most vulnerable. © 2013 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

    Cellulose porous beads (CPBs) are exceptionally uniform in size and nonabsorbable and they provide highly effective tumor devascularization. The risk of cranial nerve palsy must not be overlooked when embolization with CPBs is considered in meningioma patients. We attempted to identify patients at risk of cranial nerve palsy after meningioma embolization. Prior to preoperative superselective embolization with 200 {mu}m diameter CPBs, 141 patients with meningioma underwent provocation test with lidocaine and amytal. They were divided into two groups on the basis of whether they were or were not considered eligible for embolization. We evaluated the differences between the two groups with respect to tumor anatomy, angiographic findings, and clinical presentation and recorded complications associated with the embolization of the meningioma. Of the 141 patients, 128 underwent CPB embolization (group 2); 13 were not embolized because their provocation test results were positive (group 1, n = 11) or because they showed vasospasm (n = 2). Group 1 patients had meningioma in the cavernous sinus or petroclival region. Characteristically, the feeders were of middle meningeal artery origin and exhibited a posteromedial course toward the petrous apex or cavernous sinus. In group 2 patients the middle meningeal artery was the feeder, but it lacked branches coursing posteromedially. Three of these patients experienced complications which included intratumoral hemorrhage (n = 2) and post-embolization hearing disturbance (n = 1). Patients with meningioma whose tumor-feeding arteries run posteromedially toward the petrous apex or cavernous sinus are at increased risk of post-embolization cranial nerve palsy. Appropriate protocols, including lidocaine and amytal provocation tests, may reduce the risk of complications after CPB embolization of the external carotid territory in this group of patients.

    To understand how memories of negative events become highly accessible in the context of trauma, we tested the hypothesis that contextual information modulates how easily intrusions can be provoked by perceptual stimuli.. Healthy participants viewed pictures depicting trauma scenes either with or without accompanying moderate (i.e. survival, recovery) or severe (i.e. fatality, permanent injury) outcome information. All participants viewed the same depictions of trauma scenes. Involuntary memories for the pictures were assessed using self-report diaries and an adapted version of the Impact of Event Scales (IES). A blurred picture perceptual priming paradigm was adapted to be used as an intrusion provocation task. The severe outcome group experienced a significantly higher frequency of intrusions on the intrusion provocation task in comparison to both moderate outcome and control (no-context) conditions. The severe outcome condition did not increase intrusions on the self-report diaries or the adapted IES. There was no effect of condition on ratings for the emotionality, self-relevance, valence, or seriousness of the trauma scenes. The analogue method should not be generalized directly to incidences of real-life trauma. It was unclear why differences in intrusion frequency were found in the provocation task only. The relative amount of individual conceptual and data-driven processing adopted by the participants was not assessed. Manipulating contextual information that determines the meaning of sensory-perceptual features for a trauma scene can modulate subsequent intrusion frequency in response to visually similar cues.

    Full Text Available Measurement of the perfusion coefficient and thermal parameters of skin tissue using dynamic thermography is presented in this paper. A novel approach based on cold provocation and thermal modelling of skin tissue is presented. The measurement was performed on a person’s forearm using a special cooling device equipped with the Peltier module. The proposed method first cools the skin, and then measures the changes of its temperature matching the measurement results with a heat transfer model to estimate the skin perfusion and other thermal parameters. In order to assess correctness of the proposed approach, the uncertainty analysis was performed.

    2017-10-16

    There has been unparalleled proliferation and technological advancement of consumer unmanned aerial vehicles (UAVs) across the globe in the past several years. As witnessed over the course of insurgency tactics, it is difficult to restrict terrorists from using widely available technology they perceive as advantageous to their overall strategy. Through a review of the characteristics, consumer market landscape, tactics, and countertactics, as well as operational use of consumer-grade UAVs, this open-source report seeks to provide an introductory understanding of the terrorist-UAV landscape, as well as insights into present and future capabilities. The caveat is evaluating a developing technology haphazardly used by terrorists in asymmetric conflicts.

    2017-01-01

    Background The nature of the migraine aura and its role in migraine pathophysiology is incompletely understood. In particular, the mechanisms underlying aura initiation and the causal relation between aura and headache are unknown. The scientific investigation of aura in patients is only possible if aura can be triggered. This paper reviews potential methods for the experimental provocation of migraine aura. Methods We systematically searched PubMed for studies of experimental migraine provocation, including case reports of patients with aura and reports of the occurrence of aura following exposure to any kind of suspected trigger. Results We identified 21 provocation studies, using 13 different prospective provocation methods, and 34 case reports. In the prospective studies, aura were reported following the administration of intravenous and sublingual glyceryl trinitrate, visual stimulation, physical activity, calcitonin gene-related peptide infusion, chocolate ingestion, and the intravenous injection of insulin. In addition, carotid artery puncture has consistently been reported as a trigger of aura. Conclusions No safe and efficient method for aura provocation exists at present, but several approaches could prove useful for this purpose.

    Callous/unemotional traits (CU) moderate children's conduct problems (CP) in numerous domains, including social functioning. The present study examined whether CU traits also moderate the aggressiveness of children's social information processing (SIP) and responses to varying intensities of peer provocation. Sixty elementary school-age children (46 males) were grouped into those without CP or CU (controls, n = 32), those with CP but not CU (CP-only; n = 14), and those with both CP and CU (CPCU, n = 14). Participants completed a task that measured two aspects of SIP (response generation and hostile attribution bias) and a computerized reaction time task (CRTT) that measured behavior, affect, and communication before and after provocation under instrumental and hostile aggressive conditions. Children with CPCU generated more aggressive responses than controls on measures of SIP. On the CRTT, all children exhibited reactive aggression following high provocation, but only children with CPCU exhibited proactive aggression, and reactive aggression following low provocation; no differences in affect were found. In a series of exploratory analyses, CPCU children communicated antisocially, while CP-only communicated prosocially. Finally, children with CPCU did not seem to hold a grudge following the final instance of provocation, instead gradually returning to baseline like their non-CU peers. These distinct social cognitive and behavioral profiles hint at different etiologies of CP and CPCU, underscoring the variability of aggression in these populations.

    Periodontal inflammation is associated with morphological changes in the blood vessels which may influence the regulation of gingival blood flow (GBF). Our aim was to adapt the heat provocation test to the human gingiva to assess vascular reactivity in periodontal inflammation. GBF was recorded by Laser Doppler Flowmetry before and after heat provocation in healthy volunteers (n = 50). Heat was generated either by warm saline or a halogen lamp. The latter method was also utilized for a heat test in non-smoking and smoking patients with periodontal inflammation. The circulatory parameters were correlated to the inflammatory marker, i.e. gingival crevicular fluid (GCF) production measured by Periotron. Local application of heat caused a rapid, significant and transient increase in GBF regardless of the method used. The increase in the speed and not in the concentration of moving blood cells was responsible for increased GBF. Higher GCF values were correlated with increased peak flow, flux pulse amplitude and faster restoration of GBF after the test in non-smokers, but not in smokers. The heat test could be a valuable tool to check the vascular reactivity of gingival vessels. Moderate periodontal inflammation may facilitate gingival vascular responsiveness which can be suppressed by smoking.

    There is a huge unmet need to understand and treat pathological cognitive impairment. The development of disease modifying cognitive enhancers is hindered by the lack of correct pathomechanism and suitable animal models. Most animal models to study cognition and pathology do not fulfil either the predictive validity, face validity or construct validity criteria, and also outcome measures greatly differ from those of human trials. Fortunately, some pharmacological agents such as scopolamine evoke similar effects on cognition and cerebral circulation in rodents and humans and functional MRI enables us to compare cognitive agents directly in different species. In this paper we report the validation of a scopolamine based rodent pharmacological MRI provocation model. The effects of deemed procognitive agents (donepezil, vinpocetine, piracetam, alpha 7 selective cholinergic compounds EVP-6124, PNU-120596) were compared on the blood-oxygen-level dependent responses and also linked to rodent cognitive models. These drugs revealed significant effect on scopolamine induced blood-oxygen-level dependent change except for piracetam. In the water labyrinth test only PNU-120596 did not show a significant effect. This provocational model is suitable for testing procognitive compounds. These functional MR imaging experiments can be paralleled with human studies, which may help reduce the number of false cognitive clinical trials. © The Author(s) 2015.

    Background There are various studies on experimentally provoked 'ice-cream headache' or 'headache attributed to ingestion or inhalation of a cold stimulus' (HICS) using different provocation protocols. The aim of this study was to compare two provocation protocols. Methods Ice cubes pressed to the palate and fast ingestion of ice water were used to provoke HICS and clinical features were compared. Results The ice-water stimulus provoked HICS significantly more often than the ice-cube stimulus (9/77 vs. 39/77). Ice-water-provoked HICS had a significantly shorter latency (median 15 s, range 4-97 s vs. median 68 s, range 27-96 s). There was no difference in pain localisation. Character after ice-cube stimulation was predominantly described as pressing and after ice-water stimulation as stabbing. A second HICS followed in 10/39 (26%) of the headaches provoked by ice water. Lacrimation occurred significantly more often in volunteers with than in those without HICS. Discussion HICS provoked by ice water was more frequent, had a shorter latency, different pain character and higher pain intensity than HICS provoked by ice cubes. The finding of two subsequent HICS attacks in the same volunteers supports the notion that two types of HICS exist. Lacrimation during HICS indicates involvement of the trigeminal-autonomic reflex.

    Drug provocation tests (DPTs) are gold standard to diagnose drug allergy. Our goal was to evaluate the results and safety of diagnostic methods including DPTs during childhood. Between January 2010 and February 2013 DPTs were performed and evaluated, prospectively, in children who attended our pediatric allergy clinic with a suspected drug hypersensitivity reaction. One hundred ninety-eight suspected drug reactions in 175 patients (88 boys and 87 girls) were evaluated. The median age of the subjects at the time of the suspected drug-induced hypersensitivity reaction and at the time of the study was 56 (interquartile range [IQR] = 24-120 months) months and 76 (IQR = 35-149 months) months, respectively. Suspected drugs were beta-lactam antibiotics in 108 cases (54.5%), non-beta-lactam antibiotics in 22 cases (11.1%), and nonsteroid anti-inflammatory drugs in 52 cases (26.3%). The history was compatible with immediate-type reactions in 69 cases (34.8%). Skin-prick tests were not positive in any of the cases. Intradermal tests were positive in three cases (4%). DPTs were positive in 13 (6.8%) of 191 provocation cases, which were performed with culprit drugs. Our results suggest that a positive clinical history is not enough to make a diagnosis of drug allergy, which highlights the significance of undertaking further diagnostic evaluation especially for DPTs.

    In order to better understand why some children retaliate when they feel provoked and others do not, the present study identified "pacifistically-oriented" children who made negative interpretations in response to unambiguous provocations, yet did not endorse revenge goals, and compared them to "revenge-seeking" children who also made negative interpretations but did endorse revenge goals. Groups were identified based on seventh graders' (N = 367; 54.77% male; 22.89% racial/ethnic minority) responses to hypothetical situations in which a peer excluded and insulted them. Comparing these groups revealed that Pacifists endorsed relationship-maintaining goals and emotion regulation goals more highly than Revenge-Seekers. Revenge-Seekers reported more anger and endorsed beliefs about negative reciprocity and aggression being legitimate more highly than Pacifists. Additionally, Revenge-Seekers were more disrespect sensitive than were Pacifists, based on a measure of vigilance for signs of disrespect and expectations that others would disrespect them. Together these findings point to social-cognitive and emotion-related processes that may inhibit revenge-seeking in unambiguous provocation situations, even when children interpret the peer's behavior quite negatively.

  6. Amygdala hyperactivation during symptom provocation in obsessive–compulsive disorder and its modulation by distraction

    Full Text Available Anxiety disorders have been linked to a hyperactivated cortico-amygdalar circuitry. Recent findings highlight the amygdala's role in mediating elevated anxiety in obsessive–compulsive disorder (OCD. However, modulation of amygdala hyperactivation by attentional distraction – an effective emotion regulation strategy in healthy individuals – has not yet been examined. While undergoing functional magnetic resonance imaging twenty-one unmedicated OCD patients and 21 controls performed an evaluation and a distraction task during symptom provocation with individually tailored OCD-relevant pictures. To test the specificity of responses, additional aversive and neutral stimuli were included. Significant group-by-picture type interactions were observed within fronto–striato–limbic circuits including the amygdala. In these regions patients showed increased BOLD responses during processing of OCD triggers relative to healthy controls. Amygdala hyperactivation was present across OCD symptom dimensions indicating that it represents a common neural correlate. During distraction, we observed dampening of patients' amygdala hyperactivity to OCD-relevant stimuli. Augmented amygdala involvement in patients during symptom provocation, present across OCD symptom dimensions, might constitute a correlate of fear expression in OCD linking it to other anxiety disorders. Attentional distraction seemed to dampen emotional processing of disorder-relevant stimuli via amygdala downregulation. The clinical impact of this strategy to manage anxiety in OCD should be further elucidated.

    Full Text Available The great virtues of the Internet - ease of access, lack of regulation, vast potential audiences, and fast flow of information, among others - have been exploited by terrorist groups. Consequently, the Internet has become a useful and effective platform for terrorist organizations and their supporters. Applying para-social relationships theory, this study examines the ways terrorist groups utilize the Internet to gain sympathy and support for their appeals and goals. The case of ETA’s website (ETA - Euskadi Ta Askatasuna, an armed Basque nationalist and separatist organization, dedicated to Basque prisoners imprisoned in Ireland and fighting extradition to Spain, is used as an illustrative example of the applicability of the para-social theorem. The various tactics adopted for establishing and promoting para-social relationships between media characters and the audiences as revealed in Basque terrorist video clips on YouTube are analyzed.  

  13. Reporting explained variance

    Science.gov (United States)

    Good, Ron; Fletcher, Harold J.

    The importance of reporting explained variance (sometimes referred to as magnitude of effects) in ANOVA designs is discussed in this paper. Explained variance is an estimate of the strength of the relationship between treatment (or other factors such as sex, grade level, etc.) and dependent variables of interest to the researcher(s). Three methods that can be used to obtain estimates of explained variance in ANOVA designs are described and applied to 16 studies that were reported in recent volumes of this journal. The results show that, while in most studies the treatment accounts for a relatively small proportion of the variance in dependent variable scores., in., some studies the magnitude of the treatment effect is respectable. The authors recommend that researchers in science education report explained variance in addition to the commonly reported tests of significance, since the latter are inadequate as the sole basis for making decisions about the practical importance of factors of interest to science education researchers.

    Full Text Available The paper presents threat assessment of potential terrorist attacks to the transport infrastructure. The range of transportation infrastructure has spread and includes railway, inland waterways, road, maritime, air, intermodal transport infrastructure and intelligent transport systems (ITS. ITS service is the provision of an ITS application through a well-defined organisational and operational framework with the aim of contributing to the user safety, efficiency, comfort and/or to facilitate or support transport and travel operations. Terrorism means acts of violence committed by groups that view themselves as victimized by some notable historical wrong. Although these groups have no formal connection with governments, they usually have the financial and moral backing of sympathetic governments. Typically, they stage unexpected attacks on civilian targets, including transport infrastructure, with the aim of sowing fear and confusion. Based on the analyses, transportation infrastructure is potentially threatened with terrorism attacks, especially road and rail infrastructure (about 23 %, and to a smaller degree the maritime and air transport infrastructure (about 2 %.

  18. Learning from history: The Glasgow Airport terrorist attack.

    Science.gov (United States)

    Crichton, Gillies

    Glasgow Airport was the target of a terrorist attack on 30th June, 2007. Many people within Scotland had come to believe that Scotland was immune from terrorism. This perception was in large part informed by Scotland's experience during the protracted Troubles in Northern Ireland, during which the Provisional Irish Republican Army's mainland bombing campaign focused on targets in England, sparing both Scotland and Wales. While Glasgow Airport did not expect such an attack to take place, meticulous planning, organising and testing of plans had taken place to mitigate the unlikely event of such an attack. The attack stands up as a shining example of robust business continuity management, where the airport reopened for business as usual in less than 24 hours from the time of the attack. Little is known about how the airport handled the situation in conjunction with other responding agencies as people tend to want to focus on high-profile disasters only. Yet countless such incidents are happening worldwide on a daily basis, in which there are excellent learning opportunities, and, taken in the spirit of converting hindsight into foresight, the likelihood of similar incidents could potentially be reduced in the future.

  19. Hidden Markov Models for the Activity Profile of Terrorist Groups

    Raghavan, Vasanthan; Tartakovsky, Alexander G

    2012-01-01

    The main focus of this work is on developing models for the activity profile of a terrorist group, detecting sudden spurts and downfalls in this profile, and in general, tracking it over a period of time. Toward this goal, a d-state hidden Markov model (HMM) that captures the latent states underlying the dynamics of the group and thus its activity profile is developed. The simplest setting of d = 2 corresponds to the case where the dynamics are coarsely quantized as Active and Inactive, respectively. Two strategies for spurt detection and tracking are developed here: a model-independent strategy that uses the exponential weighted moving-average (EWMA) filter to track the strength of the group as measured by the number of attacks perpetrated by it, and a state estimation strategy that exploits the underlying HMM structure. The EWMA strategy is robust to modeling uncertainties and errors, and tracks persistent changes (changes that last for a sufficiently long duration) in the strength of the group. On the othe...

    The current study investigates the effects of subtle changes in professional women's dress on women's perceptions of power and competence. We replicate and extend Howlett, Pine, Cahill, Orakcioglu, and Fletcher's (2015) research showing women in provocative clothing are rated as less competent. We used a larger sample, tested a second independent variable, and fine-tuned the design for higher face validity. Participants (N = 198, 170 women and 29 men) from a Midwestern university in the USA rated four photographs of professionally dressed women whose blouses varied in the number of buttons left undone and whether they wore a camisole. We found main effects of buttons (undone/done) and camisoles (on/off) for participants perceptions of intelligence, competence, powerfulness, and on a global rating score. Results also showed significant interaction effects between buttons and camisoles on ratings of powerfulness. The results have many implications for how women dress professionally.

    . Because the Novaco Anger Scale and Provocation Inventory (NAS-PI) has been extensively validated with different clinical populations and lends itself to clinical case formulation, it was selected for translation and evaluation in the present multistudy project. Psychometric properties of the NAS-PI were...... investigated with samples of 477 nonclinical, 250 clinical, 167 male prisoner, and 64 male forensic participants. Anger prevalence and its relationship with other anger measures, anxiety/depression, and aggression were examined. NAS-PI was found to have high reliability, concurrent validity, and discriminant...... aggressive behavior in hospital. Regression analyses showed that higher scores on NAS increase the risk of having acted aggressively in the past and of acting aggressively in the future....

    Full Text Available Functional imaging studies of patients with Posttraumatic Stress Disorder showed wide-spread activation of mid-line cortical areas during symptom provocation i.e., exposure to trauma-related cues. The present study aimed at investigating neural activation during exposure to trauma-related pictures in patients with Acute Stress Disorder (ASD shortly after the traumatic event. Nineteen ASD patients and 19 healthy control participants were presented with individualized pictures of the traumatic event and emotionally neutral control pictures during the acquisition of whole-brain data with a 3-T fMRI scanner. Compared to the control group and to control pictures, ASD patients showed significant activation in mid-line cortical areas in response to trauma-related pictures including precuneus, cuneus, postcentral gyrus and pre-supplementary motor area. The results suggest that the trauma-related pictures evoke emotionally salient self-referential processing in ASD patients.

    Full Text Available Some patients with severe mental disorders are refractory to psychotherapeutic or psychopharmacological interventions. We present a patient who at the age of 19 developed several schizophrenia - suspect symptoms. Soon inexplicable general seizures where observed. He was treated with antipsychotics, but had two bouts of malignant neuroleptic syndrome. Electroconvulsive therapy (ECT gave some symptom relief and he continued on maintenance ECT for years with weekly intervals. Interruption of this treatment pattern rapidly increased symptom load. After seven years a lorazepam provocation test was performed as he had a new relapse after 3 weeks without ECT. In the ensuing hours his aggressiveness and nonsense speaking rapidly diminished. Kahlbaums observation of seizures as part of a catatonia was not understood in this case. The publication of the new DSM-V diagnosis of catatonia may hopefully reduce the probability of treating a patient for schizophrenia for years without access to a more targeted medication and ECT plan.

    The value of exercise as a provocative test for early renal disease in Type 1 (insulin-dependent) diabetes was re-evaluated. Three carefully characterized groups of males were studied: 10 non-diabetic controls, 16 diabetic patients (group 1) with normal urinary albumin excretion (less than 15...... micrograms/min) and 14 Albustix-negative diabetics (group 2) with increased urinary albumin excretion (15-122 micrograms/min). Assignment to a study group was made on the basis of three 24-h urine collections, and the groups were well matched for age, weight, height, and serum creatinine concentration....... The two diabetic groups were similar with regard to duration of disease (13 +/- 6 versus 16 +/- 3 years), metabolic control (HbA1c: 8.4 +/- 1.4 versus 8.7 +/- 1.3%) and degree of diabetic complications (beat-to-beat variation and retinopathy).

    Although alcohol consumption is linked to increased aggression, its neural correlates have not directly been studied in humans so far. Based on a comprehensive neurobiological model of alcohol-induced aggression, we hypothesized that alcohol-induced aggression would go along with increased amygdala and ventral striatum reactivity and impaired functioning of the prefrontal cortex (PFC) under alcohol. We measured neural and behavioral correlates of alcohol-induced aggression in a provoking vs non-provoking condition with a variant of the Taylor aggression paradigm (TAP) allowing to differentiate between reactive (provoked) and proactive (unprovoked) aggression. In a placebo-controlled cross-over design with moderate alcohol intoxication (~0.6 g/kg), 35 young healthy adults performed the TAP during functional magnetic resonance imaging (fMRI). Analyses revealed that provoking vs non-provoking conditions and alcohol vs placebo increased aggression and decreased brain responses in the anterior cingulate cortex/dorso-medial PFC (provokingalcoholalcohol specifically increased proactive (unprovoked) but not reactive (provoked) aggression (alcohol × provocation interaction). However, investigation of inter-individual differences revealed (1) that pronounced alcohol-induced proactive aggression was linked to higher levels of aggression under placebo, and (2) that pronounced alcohol-induced reactive aggression was related to increased amygdala and ventral striatum reactivity under alcohol, providing evidence for their role in human alcohol-induced reactive aggression. Our findings suggest that in healthy young adults a liability for alcohol-induced aggression in a non-provoking context might depend on overall high levels of aggression, but on alcohol-induced increased striatal and amygdala reactivity when triggered by provocation.

    With the number of cellular phone users rapidly increasing, there is a considerable amount of public concern regarding the effects that electromagnetic fields (EMFs) from cellular phones have on health. People with self-attributed electromagnetic hypersensitivity (EHS) complain of subjective symptoms such as headaches, insomnia, and memory loss, and attribute these symptoms to radio frequency (RF) radiation from cellular phones and/or base stations. However, EHS is difficult to diagnose because it relies on a person's subjective judgment. Various provocation studies have been conducted on EHS caused by Global System for Mobile Communications (GSM) phones in which heart rate and blood pressure or subjective symptoms were investigated. However, there have been few sham-controlled provocation studies on EHS with Code Division Multiple Access (CDMA) phones where physiological parameters, subjective symptoms, and perception of RF radiation for EHS and non-EHS groups were simultaneously investigated. In this study, two volunteer groups of 18 self-reported EHS and 19 non-EHS persons were tested for both sham and real RF exposure from CDMA cellular phones with a 300 mW maximum exposure that lasted half an hour. We investigated not only the physiological parameters such as heart rate, respiration rate, and heart rate variability (HRV), but also various subjective symptoms and the perception of EMF. In conclusion, RF exposure did not have any effects on physiological parameters or subjective symptoms in either group. As for EMF perception, there was no evidence that the EHS group better perceived EMF than the non-EHS group.

    Full Text Available The current study investigated the interactive effects of individual differences in automatic emotion regulation (AER and primed emotion regulation strategy on skin conductance level (SCL and heart rate during provoked anger. The study was a 2 × 2 [AER tendency (expression vs. control × priming (expression vs. control] between subject design. Participants were assigned to two groups according to their performance on an emotion regulation-IAT (differentiating automatic emotion control tendency and automatic emotion expression tendency. Then participants of the two groups were randomly assigned to two emotion regulation priming conditions (emotion control priming or emotion expression priming. Anger was provoked by blaming participants for slow performance during a subsequent backward subtraction task. In anger provocation, SCL of individuals with automatic emotion control tendencies in the control priming condition was lower than of those with automatic emotion control tendencies in the expression priming condition. However, SCL of individuals with automatic emotion expression tendencies did no differ in the automatic emotion control priming or the automatic emotion expression priming condition. Heart rate during anger provocation was higher in individuals with automatic emotion expression tendencies than in individuals with automatic emotion control tendencies regardless of priming condition. This pattern indicates an interactive effect of individual differences in AER and emotion regulation priming on SCL, which is an index of emotional arousal. Heart rate was only sensitive to the individual differences in AER, and did not reflect this interaction. This finding has implications for clinical studies of the use of emotion regulation strategy training suggesting that different practices are optimal for individuals who differ in AER tendencies.

    Full Text Available Abstract Background Determination of PC20-FEV1 during Methacholine bronchial provocation test (MCT is considered to be impossible in preschool children, as it requires repetitive spirometry sets. The aim of this study was to assess the feasibility of determining PC20-FEV1 in preschool age children and compares the results to the wheeze detection (PCW method. Methods 55 preschool children (ages 2.8–6.4 years with recurrent respiratory symptoms were recruited. Baseline spirometry and MCT were performed according to ATS/ERS guidelines and the following parameters were determined at baseline and after each inhalation: spirometry-indices, lung auscultation at tidal breathing, oxygen saturation, respiratory and heart rate. Comparison between PCW and PC20-FEV1 and clinical parameters at these end-points was done by paired Student's t-tests. Results and discussion Thirty-six of 55 children (65.4% successfully performed spirometry-sets up to the point of PCW. PC20-FEV1 occurred at a mean concentration of 1.70+/-2.01 while PCW occurred at a mean concentration of 4.37+/-3.40 mg/ml (p 1 by 44.7+/-14.5%; PEFR by 40.5+/-14.5 and FEF25–75 by 54.7+/-14.4% (P Conclusion Determination of PC20-FEV1 by spirometry is feasible in many preschool children. PC20-FEV1 often appears at lower provocation dose than PCW. The lower dose may shorten the test and encourage participation. Significant decrease in spirometry indices at PCW suggests that PC20-FEV1 determination may be safer.

    Currently bronchial provocation testing (BPT) using mannitol powder cannot be performed in children under 6 years. A primary reason is it is challenging for children at this age to generate a consistent inspiratory effort to inhale mannitol efficiently from a dry powder inhaler. A prototype system, which does not require any inhalation training from the pediatric subject, is reported here. It uses an external source of compressed air to disperse mannitol powder into a commercial holding chamber. Then the subject uses tidal breathing to inhale the aerosol. The setup consists of a commercially available powder disperser and Volumatic™ holding chamber. Taguchi experimental design was used to identify the effect of dispersion parameters (flow rate of compressed air, time compressed air is applied, mass of powder, and the time between dispersion and inhalation) on the fine particle dose (FPD). The prototype was tested in vitro using a USP throat connected to a next generation impactor. The aerosols from the holding chamber were drawn at 10 L/min. A scaling factor for estimating the provoking dose to induce a 15% reduction in forced expiratory volume in 1 second (FEV1) (PD15) was calculated using anatomical dimensions of the human respiratory tract at various ages combined with known dosing values from the adult BPT. Consistent and doubling FPDs were successfully generated based on the Taguchi experimental design. The FPD was reliable over a range of 0.8 (±0.09) mg to 14 (±0.94) mg. The calculated PD15 for children aged 1-6 years ranged from 7.1-30 mg. The FPDs generated from the proposed set up are lower than the calculated PD15 and therefore are not expected to cause sudden bronchoconstriction. A prototype aerosol delivery system has been developed that is consistently able to deliver doubling doses suitable for bronchial provocation testing in young children.

    This article hypothesized that the possibility to construct intellectual meaning of a terrorist attack (i.e., whether participants can cognitively understand why the perpetrators did their crime) reduces the negative psychological consequences typically associated with increased terrorist threat. Concretely, the authors investigated the effect of intellectual meaning (induced by providing additional information about potential economic, cultural, and historical reasons for the terrorist attack) on perceived terrorist threat and associated emotional well-being. Study 1 revealed that pictures of terrorist attacks elicited less experienced terrorist threat when they were presented with background information about the terrorists' motives (meaning provided) rather than without additional background information (no meaning provided). Study 2 replicated this effect with a different manipulation of terrorist threat (i.e., newspaper article) and clarified the underlying psychological process: Participants in the high terror salience condition with meaning provided experienced less terrorist threat and thus more emotional well-being in the face of crisis than participants in the high terror salience condition without meaning provided. Theoretical and practical implications in the context of psychological health and mass media effects are discussed.

    According to the Japanese Circulation Society guideline of vasospastic angina, incremental doses of acetylcholine (ACh) are prescribed for coronary spasm provocation: 20 and 50 μg for the right coronary artery (RCA), and 20, 50 and 100 μg for the left coronary artery (LCA). However, provocation by low doses of ACh in patients with low vasoreactivity may be less needed, and the requirement of 50 μg of ACh for the LCA in these patients has not been evaluated. In the present study, patients who underwent ACh provocation test for both the RCA and LCA were included. The positive diagnosis of intracoronary ACh provocation test was defined as total or subtotal coronary artery narrowing (i.e., angiographic coronary artery spasm) accompanied by chest pain and/or ischemic electrocardiographic changes. Coronary artery constriction was visually evaluated and defined as coronary artery diameter reduction LCA. There were 33 out of 249 patients (13%) with LCA spasm by 20 µg of ACh. In subjects without LCA spasm by 20 µg of ACh, patients with coronary constriction LCA rarely showed coronary artery spasm induced by 50 μg of ACh in the LCA, in comparison to those with coronary constriction 25-90% (n = 115) (2.6 vs. 32.7%, p LCA had cardiac complications associated with administration of ACh. In conclusion, omission of 50 µg of ACh in the LCA may be possible when there is little coronary artery constriction by 20 µg of ACh in the LCA during provocation test, leading to less contrast and shortens overall procedure time.

    Through the mathematical study of two models we quantify some of the theories of co-development and co-existence of focused groups in the social sciences. This work attempts to develop the mathematical framework behind the social sciences of community formation. By using well developed theories and concepts from ecology and epidemiology we hope to extend the theoretical framework of organizing and self-organizing social groups and communities, including terrorist groups. The main goal of our work is to gain insight into the role of recruitment and retention in the formation and survival of social organizations. Understanding the underlining mechanisms of the spread of ideologies under competition is a fundamental component of this work. Here contacts between core and non-core individuals extend beyond its physical meaning to include indirect interaction and spread of ideas through phone conversations, emails, media sources and other similar mean. This work focuses on the dynamics of formation of interest groups, either ideological, economical or ecological and thus we explore the questions such as, how do interest groups initiate and co-develop by interacting within a common environment and how do they sustain themselves? Our results show that building and maintaining the core group is essential for the existence and survival of an extreme ideology. Our research also indicates that in the absence of competitive ability (i.e., ability to take from the other core group or share prospective members) the social organization or group that is more committed to its group ideology and manages to strike the right balance between investment in recruitment and retention will prevail. Thus under no cross interaction between two social groups a single trade-off (of these efforts) can support only a single organization. The more efforts that an organization implements to recruit and retain its members the more effective it will be in transmitting the ideology to other vulnerable

    Are islamic terrorists insane? International scholars generally concede that Al Qaeda members are not mentally ill. But, until now, there has not been a shared consensus and a strong argument that can prove it. This paper intends to throw light on the specific dehumanization of terrorists and to show that they are always responsible for their acts, unlike those who are affected by mental diseases. The members of Al Qaeda deny the world of life and take the distance from its sense and value: in their perspective only subversive action makes sense. However they always maintain a transcendent relation with the world (I-you; I-it). Persons with serious mental diseases have generally lost the sense of their self and the transcendence with the world. Terrorists and people with mental illness share a common separation from the world of life: one is voluntary, the other is the consequence of a number of factors (biological, social, etc.). Terrorists and psychotics have nevertheless something in common: the deprivation of the self. A loss of being that--I argue--is at the origin of the ordinariness of terrorists and the experience of void in psychotics. Two symptoms that reveal the condition of an intimate dryness, from a phenomenological and a metaphysical point of view as a consequence of a distorted relation with the world of life. I shall discuss how ordinariness is strictly related with the blurring definition of terrorism.

  20. Explaining embodied cognition results.

    Lakoff, George

    2012-10-01

    From the late 1950s until 1975, cognition was understood mainly as disembodied symbol manipulation in cognitive psychology, linguistics, artificial intelligence, and the nascent field of Cognitive Science. The idea of embodied cognition entered the field of Cognitive Linguistics at its beginning in 1975. Since then, cognitive linguists, working with neuroscientists, computer scientists, and experimental psychologists, have been developing a neural theory of thought and language (NTTL). Central to NTTL are the following ideas: (a) we think with our brains, that is, thought is physical and is carried out by functional neural circuitry; (b) what makes thought meaningful are the ways those neural circuits are connected to the body and characterize embodied experience; (c) so-called abstract ideas are embodied in this way as well, as is language. Experimental results in embodied cognition are seen not only as confirming NTTL but also explained via NTTL, mostly via the neural theory of conceptual metaphor. Left behind more than three decades ago is the old idea that cognition uses the abstract manipulation of disembodied symbols that are meaningless in themselves but that somehow constitute internal "representations of external reality" without serious mediation by the body and brain. This article uniquely explains the connections between embodied cognition results since that time and results from cognitive linguistics, experimental psychology, computational modeling, and neuroscience.

  1. Computing Optimal Mixed Strategies for Terrorist Plot Detection Games with the Consideration of Information Leakage

    Directory of Open Access Journals (Sweden)

    Li MingChu

    2017-01-01

    Full Text Available The terrorist’s coordinated attack is becoming an increasing threat to western countries. By monitoring potential terrorists, security agencies are able to detect and destroy terrorist plots at their planning stage. Therefore, an optimal monitoring strategy for the domestic security agency becomes necessary. However, previous study about monitoring strategy generation fails to consider the information leakage, due to hackers and insider threat. Such leakage events may lead to failure of watching potential terrorists and destroying the plot, and cause a huge risk to public security. This paper makes two major contributions. Firstly, we develop a new Stackelberg game model for the security agency to generate optimal monitoring strategy with the consideration of information leakage. Secondly, we provide a double-oracle framework DO-TPDIL for calculation effectively. The experimental result shows that our approach can obtain robust strategies against information leakage with high feasibility and efficiency.

    While criminals may start their activities at individual level, the same is in general not true for terrorists who are mostly organized in well established networks. The effectiveness of a terror network could be realized by watching many factors, including the volume of activities accomplished by its members, the capabilities of its members to hide, and the ability of the network to grow and to maintain its influence even after the loss of some members, even leaders. Social network analysis, data mining and machine learning techniques could play important role in measuring the effectiveness of a network in general and in particular a terror network in support of the work presented in this chapter. We present a framework that employs clustering, frequent pattern mining and some social network analysis measures to determine the effectiveness of a network. The clustering and frequent pattern mining techniques start with the adjacency matrix of the network. For clustering, we utilize entries in the table by considering each row as an object and each column as a feature. Thus features of a network member are his/her direct neighbors. We maintain the weight of links in case of weighted network links. For frequent pattern mining, we consider each row of the adjacency matrix as a transaction and each column as an item. Further, we map entries into a 0/1 scale such that every entry whose value is greater than zero is assigned the value one; entries keep the value zero otherwise. This way we can apply frequent pattern mining algorithms to determine the most influential members in a network as well as the effect of removing some members or even links between members of a network. We also investigate the effect of adding some links between members. The target is to study how the various members in the network change role as the network evolves. This is measured by applying some social network analysis measures on the network at each stage during the development. We report

    2003-01-01

    This book is written for students at bachelor and master programs and has four different purposes, which split the book into four parts: 1. To teach first or early year undergraduate engineering students basic knowledge in technical computations and programming using MATLAB. The first part starts from first principles and is therefore well suited both for readers with prior exposure to MATLAB but lacking a solid foundational knowledge of the capabilities of the system and readers not having any previous experience with MATLAB. The foundational knowledge gained from these interactive guided tours of the system will hopefully be sufficient for an effective utilization of MATLAB in the engineering profession, in education and in research. 2. To explain the foundations of more advanced use of MATLAB using the facilities added the last couple of years, such as extended data structures, object orientation and advanced graphics. 3. To give an introduction to the use of MATLAB in typical undergraduate courses in elec...

    In the years since the first reports of mass rapes in the Yugoslavian wars of secession and the genocidal massacres in Rwanda, feminist activists and scholars, human rights organizations, journalists, and social scientists have dedicated unprecedented efforts to document, explain, and seek solutions for the phenomenon of wartime rape. While contributors to this literature agree on much, there is no consensus on causal factors. This paper provides a brief overview of the literature on wartime rape in historical and ethnographical societies and a critical analysis of the four leading explanations for its root causes: the feminist theory, the cultural pathology theory, the strategic rape theory, and the biosocial theory. The paper concludes that the biosocial theory is the only one capable of bringing all the phenomena associated with wartime rape into a single explanatory context.

    Full Text Available Terrorism is a global threat to all countries regardless their social, economic and religious setting. For the realization of their activities, terrorists use different models. As funds for realization of the terrorist act they use different types of weapons, mainly firearms. Terrorist organizations that practice modern forms of terrorism also use weapons of mass destruction. According to that, they improve the ways of getting funds for the realization of the terrorist acts, its internal organization and the ways of practicing terrorism. In this article, we will give a brief overview of the instrumentum operandi, organizational setup and phases of realization of the terrorist act, with special emphasis on the situation in the Republic of Macedonia.

  11. Conflicts in Africa and Major Powers: Proxy Wars, Zones of Influence or Provocative Instability

    2016-12-01

    Full Text Available The article analyses the different nature of conflicts that have occurred in Africa since the end of Cold War. A special attention is given to the role of external factors in the process of conflict evolution and the escalation of violence on the African continent. In effect, this paper demonstrates through a critical examination of the meaning of proxy war as, zone of influence or provocation of instability as a strategy and an analysis of its employment by the United States and China, France etc. in Africa. The new potential confrontation between the United States and China as in Sudan, France in its former coloniesis not only based on a clash of world views about the structure and nature of international relations and security but largely over the control of strategically vital energy resources based in Africa. The authors conclude that this ultimately creates permanent tensions or bitter conflicts between the actors and African populations as a factor that have negative impact on the peace and stability of continent. According to the context of superpower conflict strategies, this paper critically examines, zone of influence, provoking of instability or proxy war as a viable national strategy of nuclear armed great powers in advancing and/or defending their global national interests in a bipolar/multipolar international system.

    We examined the influence of gender and smoking status on reactivity in two human laboratory stress paradigms. Participants were 46 (21 men, 25 women) healthy individuals who completed the Trier Social Stress Task (i.e., performed speech and math calculations in front of an audience) and a pharmacological stress provocation (i.e., administration of corticotrophin releasing hormone (CRH)) after an overnight hospital stay. Approximately half (53%) of the participants were smokers. Cortisol, adrenocorticotrophin hormone (ACTH), physiologic measures (heart rate, blood pressure), and subjective stress were assessed at baseline and at several time points post-task. Men demonstrated higher baseline ACTH and blood pressure as compared to women; however, ACTH and blood pressure responses were more pronounced in women. Women smokers evidenced a more blunted cortisol response as compared to non-smoking women, whereas smoking status did not affect the cortisol response in men. Finally, there was a more robust cardiovascular and subjective response to the Trier as compared to the CRH. Although preliminary, the findings suggest that women may be more sensitive than men to the impact of cigarette smoking on cortisol response. In addition, there is some evidence for a more robust neuroendocrine and physiologic response to acute laboratory stress in women as compared to men.

  13. Fear Processing in Dental Phobia during Crossmodal Symptom Provocation: An fMRI Study

    2014-01-01

    Full Text Available While previous studies successfully identified the core neural substrates of the animal subtype of specific phobia, only few and inconsistent research is available for dental phobia. These findings might partly relate to the fact that, typically, visual stimuli were employed. The current study aimed to investigate the influence of stimulus modality on neural fear processing in dental phobia. Thirteen dental phobics (DP and thirteen healthy controls (HC attended a block-design functional magnetic resonance imaging (fMRI symptom provocation paradigm encompassing both visual and auditory stimuli. Drill sounds and matched neutral sinus tones served as auditory stimuli and dentist scenes and matched neutral videos as visual stimuli. Group comparisons showed increased activation in the insula, anterior cingulate cortex, orbitofrontal cortex, and thalamus in DP compared to HC during auditory but not visual stimulation. On the contrary, no differential autonomic reactions were observed in DP. Present results are largely comparable to brain areas identified in animal phobia, but also point towards a potential downregulation of autonomic outflow by neural fear circuits in this disorder. Findings enlarge our knowledge about neural correlates of dental phobia and may help to understand the neural underpinnings of the clinical and physiological characteristics of the disorder.

    2017-01-01

    Diagnosis of exercise-induced bronchoconstriction (EIB) requires the use of bronchial provocation tests (BPTs). We assessed exercise-induced respiratory symptoms (EIRS), EIB and asthma in athletes and evaluated the validity of BPTs in the diagnosis of EIB. Rhinitis and atopy were also assessed. Athletes with (n=55) and without previous asthma diagnosis (n=145) were tested by skin prick tests, lung function and eNO measurements. EIRS were recorded and EIB was assessed by methacholine (Mch), eucapnic voluntary hyperpnoea (EVH), mannitol and exercise test. EIRS were highly reported and history of asthma was common among athletes. A high prevalence of atopy (48.7%) and allergic rhinitis (30.5%) was found. Athletes with asthma had a higher response rate to Mch and to EVH, as compared with athletes without a previous asthma diagnosis (P=0.012 and P=0.017 respectively). Report of EIRS, rhinitis and atopy were not associated with a positive BPT response. Screening athletes for EIB using BPTs is suggested, irrespective of reported EIRS or a previous asthma diagnosis.

  15. On recent advances in human engineering Provocative trends in embryology, genetics, and regenerative medicine.

    2016-01-01

    Advances in embryology, genetics, and regenerative medicine regularly attract attention from scientists, scholars, journalists, and policymakers, yet implications of these advances may be broader than commonly supposed. Laboratories culturing human embryos, editing human genes, and creating human-animal chimeras have been working along lines that are now becoming intertwined. Embryogenic methods are weaving traditional in vivo and in vitro distinctions into a new "in vivitro" (in life in glass) fabric. These and other methods known to be in use or thought to be in development promise soon to bring society to startling choices and discomfiting predicaments, all in a global effort to supply reliably rejuvenating stem cells, to grow immunologically non-provocative replacement organs, and to prevent, treat, cure, or even someday eradicate diseases having genetic or epigenetic mechanisms. With humanity's human-engineering era now begun, procedural prohibitions, funding restrictions, institutional controls, and transparency rules are proving ineffective, and business incentives are migrating into the most basic life-sciences inquiries, wherein lie huge biomedical potentials and bioethical risks. Rights, health, and heritage are coming into play with bioethical presumptions and formal protections urgently needing reassessment.

    Cough and deglutition are protective mechanisms that defend against aspiration. We identified mechanisms associated with cough provocation as well as those associated with cough resolution in infants with bronchopulmonary dysplasia (BPD). Manometry signatures of cough were recognized in 16 premature infants with BPD undergoing concurrent esophageal manometry, respiratory inductance plethysmography, and nasal air flow measurements. Pretussive and post-tussive pharyngo-esophageal motility changes were analyzed. Mechanisms associated with cough and mechanisms that restored respiratory and esophageal normalcy were analyzed. We analyzed 312 cough events during 88 cough clusters; 97% were associated with recognizable manometric patterns. Initial mechanisms related with coughing included nonpropagating swallow (59%), upper esophageal sphincter (UES) reflex contraction (18%), and lower esophageal sphincter (LES) relaxation (14%). UES and LES dysfunction was present in 69% of nonpropagating swallow-associated cough clusters. Mechanisms restoring post-tussive normalcy included primary peristalsis (84%), secondary peristalsis (8%), and none recognized (8%). UES contraction reflex was associated with cough clusters more frequently in infants on nasal continuous positive airway pressure (NCPAP) (OR = 9.13, 95% CI = 1.88-44.24). Cough clusters in infants with BPD had identifiable etiologies associated with esophageal events; common initial mechanisms were of upper aerodigestive origin, while common clearing mechanisms were peristaltic reflexes.

  17. Climate change communication: a provocative inquiry into motives, meanings, and means.

    Science.gov (United States)

    Johnson, Branden B

    2012-06-01

    The deliberately provocative theme of this article is that perceived difficulties in climate change communication (CCC)--e.g., indifference about or denial of climate change's reality, negative consequences, anthropogenic causes, or need to mitigate or adapt to it-are partly the fault of climate change communicators. Fischhoff's model of risk communication development is used to demonstrate that CCC to date has tended to stress persuasion, rather than social movement mobilization or deliberation, and with a focus on the model's early stages. Later stages are not necessarily better, but a more diverse strategy seems superior to a focus perhaps narrowed by empathic, ideological, psychological, and resource constraints. Furthermore, even within persuasion, emphasizing a wider set of values, consequences, and audiences could be fruitful. Social movement mobilization has its own set of weaknesses, but usefully complements persuasion with a focus on developing power, subverting mainstream assumptions, and engaging people in collective action. Deliberation similarly has its drawbacks, but unlike the other two approaches does not define the solution-or even, necessarily, the problem-in advance, and thus offers the chance for people of contending viewpoints to jointly develop concepts and action agendas hitherto unimagined. Simultaneous pursuit of all three strategies can to some degree offset their respective flaws, at the potential cost of diffusion of energies and contradictory messages. Success in CCC is by no means guaranteed by a more diverse set of strategies and self-reflection by communicators, but their pursuit should better reveal CCC's limits. © 2011 Society for Risk Analysis.

    Full Text Available Purpose : There are very few reports of adverse drug reactions (ADR and almost no study of drug provocation test (DPT in Korean children. We aimed to assess the role of DPT in children with unpredictable ADRs, and compare the causative drugs and clinical characteristics between detailed history of ADRs and result of DPTs. Methods : We included 16 children who were experienced ADRs referred to pediatric allergy clinic at Ajou University Hospital (January 2006 to December 2009. With various suspected drugs, 71 DPTs were done in 16 patients using our own protocol, and skin tests to antibiotics were combined in ADRs to antibiotics in medical history. Results : There were 17 (23.9% positive DPTs results out of 71 individual DPTs, and 11 patients (68.8% from 16 patients were positive to at least one drug. Drugs causing positive reactions were acetaminophen in 5 (31%, Non-steroidal anti-inflammatory drugs in 4 (25%, penicillin in 3 (19%, cephalosporin in 2 (13%, and cotrimoxazole, macrolide and lactose in 1 each. Conclusion : DPT seems a safe and useful procedure to confirm causative drug and identify safely administering alternative drugs in children with ADR.

  1. Explaining climate danger

    Science.gov (United States)

    Oreskes, N.

    2016-12-01

    The idea of `managing planet Earth' is traceable back at least to the 1970s. Recently, it has been reformulated in the idea of a "good Anthropocene": the idea that humans should and can try to manage our planet now that we have become a planetary force. Yet available evidence and experience suggests that our prior attempts to do so have been plagued by under-estimation of the scale of the problems and over-estimation of our capacities to address them. In any case, Earth is not at risk—our planet will survive despite what we do or fail to do. Global climate change, for example, is not a problem for the planet, it is a problem for us. As the UNFCCC articulated in the 1990s, climate change matters because it is dangerous. Yet many Americans still do not understand why this is the case. I suggest that scientists can profitably focus attention on explaining this danger—why climate represents a threat to our health, well-being, and lives—and on what kinds of steps can be taken to reduce the danger.

  2. Moderating role of trait hope in the relation between painful and provocative events and acquired capability for suicide.

    2015-01-01

    The interpersonal theory of suicide has gained empirical support as a conceptualization of suicide risk; however, little research has examined the role of individual traits, such as trait hope, within the interpersonal theory of suicide. The purpose of this study was to further investigate the role of trait hope components (i.e., pathways and agency) in acquired capability for suicide. Participants were 711 college students who completed measures of acquired capability for suicide, painful and provocative events, and trait hope (i.e., pathways and agency). Linear regression was used to test the hypotheses. As hypothesized, there was a positive relation between pathways and acquired capability. Contrary to our hypotheses, after controlling for gender there was a significant relation between agency and acquired capability. In addition, after controlling for gender, pathways did not moderate the relation between painful and provocative events and acquired capability, whereas agency did moderate this relation. Painful and provocative events should be assessed as a risk factor for acquired capability for suicide, and this may be more salient for individuals higher in the agency component of trait hope. Future research should consider examining the role of other traits within the interpersonal theory of suicide.

  3. Change and Continuity in Indonesian Islamist Ideology and Terrorist Strategies

    Directory of Open Access Journals (Sweden)

    Adam James Fenton

    2015-04-01

    Full Text Available The “Islamisation” of Indonesia has exerted a transformative force on every aspect of Indonesian society. That process continues today. It has created streams of change and continuity in thoughts, ideologies and practices, of enormous complexity. Strict doctrinal interpretation of Koranic text is not a new phenomenon, contrary to what some reports in the mass media might suggest. Its roots stretch back at least as far as the 1800s with the outbreak of violent conflicts between those urging a stricter, scripturalist application of Islam, and those adhering to traditionalist and colonialist ideologies --culminating in the Padri war of West Sumatra of 1821-38. Indicating an ostensible continuity of ideology, modern extremist ideologues, such as Abu Bakar Bashir, urge their followers toward violent conflict and terrorist actions based on an ideology of strict “Middle Eastern” interpretation of fundamental Islamic tenets. This paper argues that the strategies of those carrying out radical and violent ideologies are undergoing change, as are the strategies of the authorities tasked with combating them. Radical groups have displayed a shift away from large-scale, attacks on symbolic foreign targets towards low-level violence primarily aimed at law enforcement authorities. Authorities, on the other hand, have shown a greater tendency to shoot dead those suspected of involvement with violent radical groups. This paper will examine the changing strategies of violent radical groups and the continuity, and evolution, of the underlying Islamic ideology that provides religious justification for their violent acts. The paper will argue that engaging Indonesia’s politically active youth in an ideological dialogue on Islamism and democracy provides the best prospect for disengagement from, and breaking the cycle of recruitment for, radical violence and terrorism.[Proses panjang Islamisasi di Indonesia telah menghasilkan kekuatan transformatif di

    To investigate the characteristics of pulmonary function in children with atypical asthma with chest tightness as the chief complaint before and after a bronchial provocation test. This study included 34 children with atypical asthmas who underwent bronchial provocation test between January 2010 and December 2013. Thirty-four children with typical asthmas were selected as the control group. The pulmonary function of the atypical asthma group was examined before and after the bronchial provocation test and compared with that of the control group in the acute episode and remission stages. The forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, peak expiratory flow, forced expiratory flow 25%, 50%, 75% (FEF25, FEF50, FEF75), and maximum mid-expiratory flow (MMEF75/25) in the atypical asthma group before the bronchial provocation test were (105±12)%, (104±12)%, (100±7)%, (88±13)%, (90±14)%, (81±17)%, (73±25)%, and (80±17)%, respectively; these functional indices were significantly higher than in the control group in the acute episode stage (P0.05). In addition, no significant difference in pulmonary indices was observed between the atypical asthma group after the bronchial provocation test and the control group in the acute episode stage (P>0.05), but functional indices above were significantly lower in the atypical asthma group after the bronchial provocation test than in the control group in the remission stage and the atypical asthma group before the bronchial provocation test (PBronchial provocation test is useful in the diagnosis of atypical asthma in children.

    2017-05-01

    This paper takes central China power grid (CCPG) as an example, and analyzes the vulnerability of the power systems under terrorist attacks. To simulate the intelligence of terrorist attacks, a method of critical attack area identification according to community structures is introduced. Meanwhile, three types of vulnerability models and the corresponding vulnerability metrics are given for comparative analysis. On this basis, influence of terrorist attacks on different critical areas is studied. Identifying the vulnerability of different critical areas will be conducted. At the same time, vulnerabilities of critical areas under different tolerance parameters and different vulnerability models are acquired and compared. Results show that only a few number of vertex disruptions may cause some critical areas collapse completely, they can generate great performance losses the whole systems. Further more, the variation of vulnerability values under different scenarios is very large. Critical areas which can cause greater damage under terrorist attacks should be given priority of protection to reduce vulnerability. The proposed method can be applied to analyze the vulnerability of other infrastructure systems, they can help decision makers search mitigation action and optimum protection strategy.

  18. In Their Own Words? Methodological Considerations in the Analysis of Terrorist Autobiographies

    Directory of Open Access Journals (Sweden)

    Mary Beth Altier

    2012-01-01

    Full Text Available Despite the growth of terrorism literature in the aftermath of the 9/11 attacks, there remain several methodological challenges to studying certain aspects of terrorism. This is perhaps most evident in attempts to uncover the attitudes, motivations, and intentions of individuals engaged in violent extremism and how they are sometimes expressed in problematic behavior. Such challenges invariably stem from the fact that terrorists and the organizations to which they belong represent clandestine populations engaged in illegal activity. Unsurprisingly, these qualities make it difficult for the researcher to identify and locate willing subjects of study—let alone a representative sample. In this research note, we suggest the systematic analysis of terrorist autobiographies offers a promising means of investigating difficult-to-study areas of terrorism-related phenomena. Investigation of autobiographical accounts not only offers additional data points for the study of individual psychological issues, but also provides valuable perspectives on the internal structures, processes, and dynamics of terrorist organizations more broadly. Moreover, given most autobiographies cover critical events and personal experiences across the life course, they provide a unique lens into how terrorists perceive their world and insight into their decision-making processes. We support our advocacy of this approach by highlighting its methodological strengths and shortcomings.

    2004-11-01

    The aim of this study was to correlate the MR imaging abnormalities of the lumbar intervertebral discs, with emphasis being placed on the high intensity zone (HIZ) with the use of discography for pain provocation and disc morphologic evaluation of the disc. Consecutive patients with low back pain unresponsive to conservative treatment, and who were being considered for spinal fusion had MRI performed, and this was followed by lumbar discography. The MR imaging, discography and CT discography (CTD) were evaluated for all of the 19 patients. Forty-three lumbar discs in 19 patients were included in this study. The findings of MR and CTD images were evaluated retrospectively with the professional opinion and agreement of two radiologists. MR images were assessed for the presence or absence of decreased T2-wighted signal intensity, decreased disc height, annular bulging, HIZ on T2-weighted images and disc herniation. The results of pain provocation were graded as 0, nonconcordant pain; 1, definite pain, but only as part of the symptom complex; 2, concordant pain. The morphology of CTD was analyzed for presence or absence of disc degeneration, radial tearing and extravasation of the contrast agent. The presence of radial tearing was defined as contrast extension to the outer third of the annulus. The prevalence of all MR abnormalities was calculated, and the data were compared with disc morphologic characteristics and the pain response on provocative discography. We used the chi-square test to analyze the results. Grade 1 and 2 discogenic pain was observed in 8 (19%) and 12 disc levels (28%), respectively. All of the seven non-degenerated discs on MR had no pain response. The decreased SI on T2-weighted image, annular bulging and HIZ were significantly correlated with discogenic pain. Extravasation of contrast media had good correlation with annular bulging and disc herniation on MRI. Radial tearing on CT discography correlated significantly with HIZ. The HIZ was

    Terrorism is no longer an issue without effect on the American mind. We now live with the same concerns and fears that have been commonplace in other developed and third world countries for a long time. Citizens of other countries have long lived with the specter of terrorism and now the U.S. needs to be concerned and prepared for terrorist activities.T he terrorist has the ability to cause great destructive effects by focusing their effort on unaware and unprepared civilian populations. Attacks can range from simple explosives to sophisticated nuclear, chemical and biological weapons. Intentional chemical releases of hazardous chemicals or chemical warfare agents pose a great threat because of their ready availability and/or ease of production, and their ability to cause widespread damage. As this battlefront changes from defined conflicts and enemies to unnamed terrorists, we must implement the proper analytical tools to provide a fast and efficient response. Each chemical uses in a terrorists weapon leaves behind a chemical signature that can be used to identify the materials involved and possibly lead investigators to the source and to those responsible. New tools to provide fast and accurate detection for battlefield chemical and biological agent attack are emerging. Gas chromatography/mass spectrometry (GC/MS) is one of these tools that has found increasing use by the military to respond to chemical agent attacks. As the technology becomes smaller and more portable, it can be used by law enforcement personnel to identify suspected terrorist releases and to help prepare the response; define contaminated areas for evacuation and safety concerns, identify the proper treatment of exposed or affected civilians, and suggest decontamination and cleanup procedures.

  1. Dutch Suspects of Terrorist Activity: A Study of Their Biographical Backgrounds Based on Primary Sources.

    Full Text Available With the impending defeat of ISIS in Syria and Iraq, supporters of terrorist groups, among them home-grown supporters and returning foreign fighters, have become a huge security threat to their country of return. Some have committed attacks in western countries, even while under the surveillance of authorities. Counter-terrorism is confronted with enormous challenges. One of the most prominent issues is the absence of evidence based knowledge on early warning signs. Experts on radicalization and terrorism have emphasized that neither typologies of terrorists nor accurate descriptions of generalizable risks can be made. This leads to opportunities for those who are willing to prepare and commit acts of terrorism to do so, without the agencies in charge of monitoring such individuals being able to accurately identify relevant threats. An additional deficiency in counter-terrorism research, is its dependency on historic and secondary source material. One of various actors in the Netherlands tasked to evaluate and mitigate relevant risks of terrorist suspects and offenders, is the Dutch Probation Service (DPS. In response to today’s prevailing terrorist threat, a specialized section of the DPS is set up to identify and supervise potential problem behaviour of those who are suspected or convicted of terrorism. The authors have been involved in this Unit Terrorism, Extremism and Radicalization (TER for years. As professionals of TER, the authors have had unique access to both judicial data, such as police files and prosecutor’s data, as to experts in the Dutch field of counter-terrorism. The authors have analysed the pre-sentencing advices of twenty-six clients of the DPS. These files are comprised of several socio-economic, historical, psychopathological and behavioural indicators. The goals are to learn from the analysis of the biographical backgrounds of the suspects and to stimulate the debate on management and supervision of terrorist

    True IgE-mediated hypersensitivity to opioids is rare and many reactions are due to direct mast cell degranulation. Opioid drug provocation testing (DPT) is the gold standard for diagnosis but is underutilized. The objective of this study was to evaluate the clinical characteristics and predictors of opioid hypersensitivity, as well as outcomes of opioid DPT. Patients referred for opioid DPT over the past 9 years were studied. Patient characteristics, indications for opioid use, symptoms of index reaction, and outcomes of DPT were analyzed. Association analysis was performed to study variables associated with a diagnosis of opioid hypersensitivity. Of the total of 98 patients referred with suspected opioid hypersensitivity, 15 (15%) were diagnosed with opioid allergy. Angioedema (odds ratio [OR]: 5.66; 95% confidence interval [CI]: 1.49-21.47; P = .011) and hypotension (OR: 5.00; 95% CI: 1.15-21.70; P = .032) were significantly more frequent in opioid allergic patients than those with a negative DPT. Patients who received opioids during anesthesia were significantly more likely to be opioid allergic (OR: 6.74; 95% CI: 2.05-22.13; P = .001). In contrast, a negative association was identified with patients who received opioids for analgesia (OR: 0.27; 95% CI: 0.08-0.86; P = .008). Only 15% of our cohort were diagnosed with opioid allergy, emphasizing the importance of DPT in preventing erroneous overdiagnosis. Patients with a history of angioedema or hypotension as their index reaction were significantly more likely to be opioid allergic. DPT are safe when performed by experienced clinicians after risk stratification and using individualized protocols. Copyright © 2017 American Academy of Allergy, Asthma & Immunology.

    The drug provocation test (DPT) is the gold standard to rule out drug hypersensitivity. There are standardized DPT protocols to diagnose immediate reactions to drugs, but not for nonimmediate reactions. The aim of this study was to show the sensitivity and specificity of an allergy work-up that included a 5-day DPT in children with histories of nonimmediate reactions to amoxicillin through focusing on a pediatric population with histories of immediate and nonimmediate reactions to amoxicillin. Two hundred consecutive patients with histories of amoxicillin reactions referred to the Allergy Unit of Anna Meyer Children's Hospital for suspected drug allergy from 2008 to 2011 underwent in vivo tests with the culprit drug according to European Academy of Allergy and Clinical Immunology guidelines. Moreover, most of those children, regardless of the skin tests results, were challenged with amoxicillin for a total of 5 days. In 4 years, 200 patients were evaluated for a history of drug hypersensitivity to amoxicillin. The majority of patients (76%) had a history of mild nonimmediate reactions. All 200 patients underwent skin tests, and 9 of 200 tested positive. A total of 177 DPTs were performed with amoxicillin for 5 days in each child. Diagnosis of amoxicillin allergy was confirmed by a DPT in 17 patients (9.6%); 14/17 had history of nonimmediate reactions; 4/14 (26.6%) reacted on day 5. According to our results, a long-term DPT protocol increases the sensitivity of the allergy work-up, and it should be recommended for patients with a history of amoxicillin nonimmediate reaction.

    Vocal cord dysfunction (also called paradoxical vocal cord motion) or paradoxical vocal fold motion (PVFM) is an event elicited by specific and nonspecific triggers in which its diagnosis is limited by the restricted number of available functional tests. This study was designed to appreciate the contribution of the spirometric changes elicited by the allergen-specific nasal provocation test (NPT) performed with Dermatophagoides pteronyssinus for the diagnosis of PVFM in subjects with known sensitization to this allergen. In total, 63 subjects with allergic rhinitis who had previously been shown to be sensitized to D. pteronyssinus and who had experienced one or more episodes of inspiratory shortness of breath underwent two spirometric tests, one before (pre-NPT) and another 15 minutes after the allergen-specific NPT (post-NPT). The forced inspiratory vital capacity (FIVC), forced inspiratory volume in 2 seconds (FIV2), and the ratio between the FIV in 1 second and FIVC (FIV1/FIVC) were measured by spirometry. The morphology of the post-NPT inspiratory loop was compared with the pre-NPT inspiratory loop. We found that 18 subjects (28.5%) showed alterations suggestive of PVFM on post-NPT spirometry (e.g., truncation and/or flattening of the inspiratory loop). The mean differences between the pre-NPT and post-NPT values for the whole group were significant using a two-tailed paired t-test for the FIVC (4.1; 95% confidence interval [CI95%], 1.4-6.8), FIV1/FIVC ratio (2.7; CI95%, 0.05-5.3), and FIV2 (7.2; CI95%, 3.4-11). Allergen-specific NPT combined with spirometry is useful to show allergen-specific laryngeal hyperresponsiveness in allergic subjects with PVFM.

    The aims of the present study were to investigate the clinical value of the provocative clinical tests and propose a composite index for the assessment of painful shoulder, using ultrasonography (US) as reference method. Two hundred three patients with painful shoulder underwent both clinical and US evaluations. The physical examination was carried out performing the Hawkins, Jobe, Patte, Gerber, and Speed tests. Each test was included in a composite index namely, SNAPSHOT (Simple Numeric Assessment of Pain by SHOulder Tests). The US examination was performed by a rheumatologist experienced in US and blinded to clinical findings. Sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratio of each clinical test were calculated. The receiver operating characteristic (ROC) curve analysis was used to assess the performance of the composite SNAPSHOT index. Sensitivity was low for the clinical diagnosis of all shoulder abnormalities. The highest sensitivity and smallest negative likelihood ratio were found for the Hawkins (63.88% and 0.50%) and Patte (62.21% and 0.52%) tests. Specificity was good for Speed (76.33%), Gerber (75.42%), and Patte (74.20%) tests. Patte and Speed tests were the most accurate (71.12% and 66.41%, respectively). The calculated area under the ROC curve related to the SNAPSHOT composite index was 0.881 +/- 0.026. With an optimal cut-off point of 3, the sensitivity and specificity were 75.8% and 87.5%, respectively. The results of the present study showed that SNAPSHOT is a feasible, informative and quantitative composite index for the assessment of painful shoulder in the clinical setting.

    Drug provocation tests (DPTs) are important in the treatment of patients with drug hypersensitivity (DH), but they carry certain hypersensitivity reaction risks, which lead to procedure-related concerns in patients. To investigate DPT-related anxiety and its effect on long-term use of tested drugs. The study included patients who underwent DPT from July 1, 2009, to July 1, 2012. After recording the patients' history and characteristics, a variety of psychiatric (Hospital Anxiety and Depression Scale, Panic and Agoraphobia Scale, and the Maudsley Obsessive-Compulsive Inventory) and quality-of-life (36-item Short Form Health Survey) tests were performed. DPT-related anxiety was also evaluated using a visual analog scale. The patients were requestioned about whether they had used the tested drug within 1 year. A total of 126 patients were included in the study. According to the Hospital Anxiety and Depression Scale, 23.4% and 30.6% of the patients had depression and anxiety symptoms, respectively. The mean (SD) visual analog scale anxiety scores after a negative DPT result were lower than those before DPTs (2 [2.5] after vs 5.2 [3.4] before; P anxiety related to drug reactions, despite negative DPT results and symptoms indicated for use of the drug. Our findings suggest that DPTs in themselves cause significant anxiety in patients with DH. Importantly, anxiety levels decreased after a negative test result. However, our results also suggested that a negative DPT result is not convincing enough for some patients to use the tested drug when needed in the future. Therefore, supporting strategies appear to be the most effective way to eliminate DH-related anxiety of patients. Copyright © 2016 American College of Allergy, Asthma & Immunology.

    Adverse drug reactions (ADRs) are a common healthcare problem. The drug provocation test (DPT) is a gold standard for ADR diagnosis. To evaluate a correlation between history of ADRs, skin prick test (SPT), intradermal test (ID) and DPT in Thai children. This was a retrospective review of 211 children under 16 years of age who had a history of ADRs and underwent DPT from January 2006 to December 2012. Two hundred and thirty six (236) DPTs were performed in 211 children with a history of ADRs. The median age at which DPTs were performed was 4 years. Thirty-four children (14.4%) had positive DPT. The positive predictive value (PPV), negative predictive value (NPV), sensitivity, specificity, likelihood ratio (LR) + and LR- of SPT were 50, 85.7, 6.9, 98.8%, 5.8 and 0.9, respectively. The PPV, NPV, sensitivity, specificity, LR+ and LR- of ID were 33.3, 84.6, 20, 91.7%, 2.4 and 0.9, respectively. Different presentation of symptoms (maculopapular rashes, urticaria, angioedema and anaphylaxis) did not predict SPT, ID and DPT results. Positive human immunodeficiency virus (HIV), but not atopy, was a risk in the present scope of evaluation for drug allergy (odds ratio 11.44, 95% confidence interval 2.60-50.41). Drug allergy, denoted by positive DPT, was present in 14.4% of Thai children with a history of ADRs. Antibiotics were the most common cause of ADRs. Both SPT and ID had high NPV and specificity but did not predict DPT results. HIV positivity is a risk factor of drug allergy in Thai children.

    Central and peripheral neural regulation of swallowing and aerodigestive reflexes is unclear in human neonates. Functional near infrared spectroscopy (NIRS) is a noninvasive method to measure changes in oxyhemoglobin (HbO) and deoxyhemoglobin (HbD). Pharyngoesophageal manometry permits evaluation of aerodigestive reflexes. Modalities were combined to investigate feasibility and to test neonatal frontoparietal cortical changes during pharyngoesophageal (visceral) stimulation and/or swallowing. Ten neonates (45.6 ± 3.0 wk postmenstrual age, 4.1 ± 0.5 kg) underwent novel pharyngoesophageal manometry concurrent with NIRS. To examine esophagus-brain interactions, we analyzed cortical hemodynamic response (HDR) latency and durations during aerodigestive provocation and esophageal reflexes. Data are presented as means ± SE or percent. HDR rates were 8.84 times more likely with basal spontaneous deglutition compared with sham stimuli (P = 0.004). Of 182 visceral stimuli, 95% were analyzable for esophageal responses, 38% for HDR, and 36% for both. Of analyzable HDR (n = 70): 1) HbO concentration (μmol/l) baseline 1.5 ± 0.7 vs. 3.7 ± 0.7 poststimulus was significant (P = 0.02), 2) HbD concentration (μmol/l) between baseline 0.1 ± 0.4 vs. poststimulus −0.5 ± 0.4 was not significant (P = 0.73), and 3) hemispheric lateralization was 21% left only, 29% right only, and 50% bilateral. During concurrent esophageal and NIRS responses (n = 66): 1) peristaltic reflexes were present in 74% and HDR in 61% and 2) HDR was 4.75 times more likely with deglutition reflex vs. secondary peristaltic reflex (P = 0.016). Concurrent NIRS with visceral stimulation is feasible in neonates, and frontoparietal cortical activation is recognized. Deglutition contrasting with secondary peristalsis is related to cortical activation, thus implicating higher hierarchical aerodigestive protective functional neural networks. PMID:24789204

    Hypothermic responses accompany motion sickness in humans and can be elicited by provocative motion in rats. We aimed to determine the potential role in these responses of the efferent cholinergic vestibular innervation. To this end, we used knockout (KO) mice lacking α9 cholinoreceptor subunit predominantly expressed in the vestibular hair cells and CBA strain as a wild-type (WT) control. In WT mice, circular horizontal motion (1Hz, 4cm radius, 20min) caused rapid and dramatic falls in core body temperature and surface head temperature associated with a transient rise in the tail temperature; these responses were substantially attenuated in KO mice; changes were (WT vs. KO): for the core body temperature-5.2±0.3 vs. -2.9±0.3°C; for the head skin temperature-3.3±0.2 vs. -1.7±0.2°C; for the tail skin temperature+3.9±1.1 vs+1.1±1.2°C. There was a close correlation in the time course of cooling the body and the surface of the head. KO mice also required 25% more time to complete a balance test. We conclude: i) that the integrity of cholinergic efferent vestibular system is essential for the full expression of motion-induced hypothermia in mice, and that the role of this system is likely facilitatory; ii) that the system is involvement in control of balance, but the involvement is not major; iii) that in mice, motion-induced body cooling is mediated via increased heat flow through vasodilated tail vasculature and (likely) via reduced thermogenesis. Our results support the idea that hypothermia is a biological correlate of a nausea-like state in animals. Copyright © 2017 Elsevier Inc. All rights reserved.

    The goals of this study were to determine the value of the isoproterenol (ISO) head-up tilt (HUT) test in detecting coronary vasospastic angina and to investigate the possible mechanism responsible for coronary artery spasm. The ISO + HUT test was performed in 16 patients with coronary artery spasm documented by the intracoronary ergonovine provocation test. Patients' blood pressure and heart rate were measured at baseline, during the ISO + HUT (phase I), and during HUT after discontinuation of ISO (phase II). Patients were categorized as test-positive if they developed angina with ST-segment elevation during testing. Eight patients (50%) were test-positive (5 in phase I and 3 in phase II). Between the test-positive and test-negative groups, no significant differences were noted in the changes in blood pressure throughout the test. However, there were significant differences in the changes in heart rate from supine to 2 minutes after HUT under ISO infusion (-17 +/-22 vs 11 +/-25 beats/minute; p=0.035). In those patients with a positive result in the phase I stage, the heart rate decreased initially after tilt-up, and then significantly increased later (from 85 +/-16 to 110 +/-27 beats/minute; p=0.043), when coronary vasospasm occurred. In those patients with a positive result in the phase II stage, coronary vasospasm occurred immediately after HUT, when there was an insignificant transient increase in heart rate from the supine to the HUT position (from 85 +/-12 to 92 +/-11 beats/minute; p=0.109). The ISO + HUT test can provoke coronary vasospasm with ST-segment elevation in 50% of the patients with coronary artery spasm, when combined with an extensional protocol of HUT after discontinuation of ISO. This study suggests that the induction of coronary artery spasm during HUT testing is associated with a rapid elevation of sympathetic activity during augmented parasympathetic activity.

    As terrorism on all scales continues, it is necessary to improve understanding of terrorist and insurgent activities. This article takes a Geographic Information Systems (GIS) approach to advance the understanding of spatial, social, political, and cultural triggers that influence terrorism incidents. Spatial, temporal, and spatiotemporal patterns of terrorist attacks are examined to improve knowledge about terrorist systems of training, planning, and actions. The results of this study aim to provide a foundation for understanding attack patterns and tactics in emerging havens as well as inform the creation and implementation of various counterterrorism measures.

    The single greatest threat to U.S. homeland security remains the proliferation of nuclear weapons, especially among terrorists and other non-state actors who are not governed by the Non-Proliferation Treaty. One of the most important tools for combating terrorism among such rogue actors is counter-financing. Without funding, terrorists cannot acquire, maintain, or deploy nuclear weapons. According to the official report of the 9/11 Commission, counter-financing could have prevented the attacks of September 11, 2001. Unfortunately, no single country can defeat global terrorism. Successful counter-financing requires significant international cooperation. Since 2001, the United States and the European Union, despite vastly different approaches to intelligence gathering, have shared information through the Terrorist Finance Tracking Program (TFTP). That shared information allows authorities to trace suspicious transactions, identify culprits, and map out global terrorist networks. The TFTP successfully thwarted a 2011 plot to assassinate the Saudi Arabian Ambassador to the U.S. and multiple threats during the 2012 Summer Olympics in London; it also aided in the investigation of the 2013 Boston Marathon bombing. That program is necessary but not sufficient. To strengthen our ability to detect and disrupt terrorist plotting and prevent nuclear proliferation, we must expand and coordinate two additional transnational measures: (1) the Society for Worldwide Interbank Financial Telecommunications (SWIFT), a standardized global messaging network for financial institutions to quickly, accurately, and securely send and receive money transfer instructions, and (2) International Bank Account Numbers (IBAN) to identify individual accounts involved in international transactions. Both initiatives were incompletely adopted in the wake of 9/11, but most global banks use one or neither. More fully implementing and coordinating these two systems would allow for coherent information

    Terrorists have used the explosive device successfully globally, with their effects extending beyond the resulting injuries. Suicide bombings, in particular, are being increasingly deployed due to the devastating effect of a combination of high lethality and target accuracy. The aim of this study was to identify trends and analyse the demographics and casualty figures of terrorist bombings worldwide. Analysis of the Global Terrorism Database (GTD) and a PubMed/Embase literature search (keywords "terrorist", and/or "suicide", and/or "bombing") from 1970 to 2014 was performed. 58,095 terrorist explosions worldwide were identified in the GTD. 5.08% were suicide bombings. Incidents per year are increasing (PEurope (13.2%) ranked 4th. The literature search identified 41 publications reporting 167 incidents of which 3.9% detailed building collapse (BC), 60.8% confined space (CS), 23.5% open space (OS) and 11.8% semi-confined space (SC) attacks. 60.4% reported on suicide terrorist attacks. Overall 32 deaths and 180 injuries per incident were seen, however significantly more deaths occurred in explosions associated with a BC. Comparing OS and CS no difference in the deaths per incident was seen, 14.2(SD±17.828) and 15.63 (SD±10.071) respectively. However OS explosions resulted in significantly more injuries, 192.7 (SD±141.147), compared to CS, 79.20 (SD±59.8). Extremity related wounds were the commonest injuries seen (32%). Terrorist bombings continue to be a threat and are increasing particularly in the Middle East. Initial reports, generated immediately at the scene by experienced coordination, on the type of detonation (suicide versus non-suicide), the environment of detonation (confined, open, building collapse) and the number of fatalities, and utilising the Kill:Wounded ratios found in this meta-analysis, can be used to predict the number of casualties and their likely injury profile of survivors to guide the immediate response by the medical services and the

    Full Text Available The article’s objective is to determine the mechanism for implementing the financial instruments of the state policy to counter terrorist acts in the territory not controlled by Ukrainian authorities in Donetsk and Luhansk regions. Methodology. Within the scientific research, for the most effective approaches at the national level to prevent the threat of international terrorism, under the conditions of the deep internal political crisis and extremely difficult economic situation, in order to improve the efficiency of public administration in developing and implementing the anti-terrorism state policies in Ukraine, the paper analyses international and domestic regulations on preventing the terrorist financing, considers factors that affect the deterioration of the social and economic situation of the temporarily occupied parts of Donbas. Results of the research allow formulating the definition of financial instruments of antiterrorist policies, the paper develops and proposes a series of organizational measures in order to prevent the terrorist financing in Ukraine. Practical implications. Based on the above, we propose an option of classification of main illegal mechanisms that may be used to finance terrorist activities in the territories of Donetsk and Luhansk regions uncontrolled by Ukrainian authorities, dividing them into internal and external. Given the above studied factors and classification of financing of terrorist acts in eastern Ukraine, we can assume that for the purpose of evading duty payable to relevant state bodies of Ukraine, external supplies of inventories in the uncontrolled areas of the Donetsk region, which are later obtained by illegal armed groups, are possibly carried out as follows: on behalf of a commercial entity registered in a foreign country for the Ukrainian commercial entity, registered in settlements located in the uncontrolled territory; crossing of international transit traffic that moves through the

    To determine the diagnostic performance (ie, sensitivity, specificity, interrater reliability) of the thumb metacarpal adduction and extension tests against traditional examination maneuvers for trapeziometacarpal (TMC) arthritis. This cross-sectional study recruited 129 patients from 2 outpatient offices at a tertiary institution. All patients had radiographic wrist examinations and completed a standardized physical examination consisting of the thumb adduction and extension tests as well as standard examination maneuvers for radial wrist and thumb pain. The physical examinations were performed by 1 of 2 attending physicians and an independent examiner. Patients were recruited for 3 diagnostic groups: TMC arthritis, radial wrist or hand pain, and nonradial wrist pain controls. Statistical analysis calculated the sensitivity, specificity, and interrater reliability of each physical examination maneuver for detecting TMC arthritis. The thumb adduction maneuver was found to have a sensitivity of 0.94 (confidence interval [CI], 0.82-0.98) and a specificity of 0.93 (CI, 0.86-0.97). The thumb extension maneuver had a sensitivity of 0.94 (CI, 0.82-0.98) and a specificity of 0.95 (CI, 0.87-0.98). The interrater reliability was excellent for both the adduction (κ = 0.79) and the extension tests (κ = 0.84). The grind test had a sensitivity of 0.44 (CI, 0.30-0.59), a specificity of 0.92 (CI, 0.84-0.97), and poor interrater reliability (0.31). Point tenderness at the TMC joint had a sensitivity of 0.94 (CI, 0.82-0.98), a specificity of 0.81 (CI, 0.71-0.88) and fair interrater reliability (κ = 0.63). The adduction and extension tests each proved to be more sensitive than the grind test for the detection of TMC arthritis. Further, these provocative tests were more specific for basal joint arthrosis than was the elicitation of point tenderness at the joint. The metacarpal adduction and extension maneuvers demonstrated excellent utility as screening tests for the

    Long-term clinical outcome data according to severity of coronary artery spasm (CAS) as assessed by an intracoronary acetylcholine provocation test are limited in series of Asian patients. To investigate 5-year clinical outcomes in patients with CAS according to CAS severity. In total, 5873 consecutive patients with insignificant coronary artery disease (<70% fixed stenosis) who underwent an acetylcholine provocation test were enrolled and divided into four groups according to CAS severity during the acetylcholine provocation test: negative, borderline positive, moderately positive and severely positive. CAS severity was assessed by quantitative coronary angiography. We investigated 5-year clinical outcomes according to CAS severity. Over a follow-up period of up to 5 years, before adjustment, the severely-positive CAS group showed a significantly higher incidence of major adverse cardiac events (MACE; composite of death, myocardial infarction and de novo revascularization) (hazard ratio [HR]: 1.834, 95% confidence interval [CI]: 1.047-3.211; P=0.033), total death (HR: 3.124, 95% CI: 1.047-9.322; P=0.041), myocardial infarction (HR: 3.190, 95% CI: 1.069-9.519; P=0.037) and recurrent angina (HR: 1.762, 95% CI: 1.363-2.278; P<0.001) compared with the negative group. However, after adjustment for baseline confounders, only the incidence of recurrent angina (HR: 1.323, 95% CI: 1.014-1.726; P=0.039) was significantly higher in the severely-positive CAS group compared with the negative group. The severity of CAS in the positive group was not associated with an increased incidence of MACE after adjustment for covariates compared with the negative group, but the severely-positive CAS group was associated with a higher incidence of recurrent angina compared with the negative group.

    This paper describes an experimental setup for evaluating the physiological effects of radiofrequency (RF) emitted from a Wideband Code Division Multiple Access (WCDMA) module with a 24 dBm at 1950 MHz for specific absorption rate (SAR(1g)) of 1.57 W/kg. This provocation study was executed in a double-blind study of two volunteer groups of 10 self-reported electromagnetic hypersensitivity (EHS) and 10 non-EHS subjects under both sham and real exposures in a randomly assigned and counter-balanced order. In the preliminary results, WCDMA RF exposure of 30 min did not have any effects on physiological changes in either group.

  2. Offensive Counterterrorism Targeted killing in eliminating terrorist target: the case of the USA and Israel

    2012-01-01

    Full Text Available Due to the "global terrorism project", some States have adopted offensive counterterrorism measures which, though within national strategies on security and defense, contemplate the use of military power and the use of lethal force against non-state actors - individuals, groups or terrorist organizations - beyond their national borders. Reformulating the security paradigm has led, in these cases, to policies against terrorism. This is the case of targeted killing - the killing of selected targets - by the USA and Israel. Targeted killing actions - using essentially but not only drones - in Pakistan and Yemen by the American administration, a well as the Israeli response to Palestinian terrorism, are under heated debate in terms of their efficiency and legality. Thus, this paper aims to not only provide an analytical framework on this theme but also analyze the scope and impact of these counter terrorist strategies by the two countries.

    Full Text Available This article summarising some findings from a doctoral dissertation discusses European converts to Islam. It explores the conditions under which conversion leads to radicalisation and terrorist violence; it analyses recrudescent concomitances of causal mechanisms of this phenomenon. Furthermore, it explores possible pathways existing between conversion, radicalisation and terrorist violence; identifies key variables pertaining to causal pathways and processes; provides hypotheses regarding the radicalisation pathways, and establishes a typology that can serve as a basis for further studies. By dispelling stereotypes on European New Muslims (ENM this research note offers a new, contextual approach to the issue under consideration. In doing so it invites the reader to reconsider the concepts of “convert”, “radicalisation” and “potential”- concepts crucial for questioning the widely expressed assumptions that European converts to Islam are a homogenous “risk group” and a security threat.

    Ackerman, Gary A; Zhuang, Jun; Weerasuriya, Sitara

    2017-02-01

    This article uses a game-theoretic approach to analyze the risk of cross-milieu terrorist collaboration-the possibility that, despite marked ideological differences, extremist groups from very different milieus might align to a degree where operational collaboration against Western societies becomes possible. Based upon theoretical insights drawn from a variety of literatures, a bargaining model is constructed that reflects the various benefits and costs for terrorists' collaboration across ideological milieus. Analyzed in both sequential and simultaneous decision-making contexts and through numerical simulations, the model confirms several theoretical arguments. The most important of these is that although likely to be quite rare, successful collaboration across terrorist milieus is indeed feasible in certain circumstances. The model also highlights several structural elements that might play a larger role than previously recognized in the collaboration decision, including that the prospect of nonmaterial gains (amplification of terror and reputational boost) plays at least as important a role in the decision to collaborate as potential increased capabilities does. Numerical simulation further suggests that prospects for successful collaboration over most scenarios (including operational) increase when a large, effective Islamist terrorist organization initiates collaboration with a smaller right-wing group, as compared with the other scenarios considered. Although the small number of historical cases precludes robust statistical validation, the simulation results are supported by existing empirical evidence of collaboration between Islamists and right- or left-wing extremists. The game-theoretic approach, therefore, provides guidance regarding the circumstances under which such an unholy alliance of violent actors is likely to succeed. © 2016 Society for Risk Analysis.

  11. TERRORIST PROTECTION PLANNING USING A RELATIVE RISK REDUCTION APPROACH, SESSION VIII: TECHNOLOGY FORUM FOCUS GROUPS.

    Energy Technology Data Exchange (ETDEWEB)

    INDUSI,J.P.

    2003-06-16

    Since the events of 9/11, there have been considerable concerns and associated efforts to prevent or respond to acts of terrorism. Very often we hear calls to reduce the threat from or correct vulnerabilities to various terrorist acts. Others fall victim to anxiety over potential scenarios with the gravest of consequences involving hundreds of thousands of casualties. The problem is complicated by the fact that planners have limited, albeit in some cases significant, resources and less than perfect intelligence on potential terrorist plans. However, valuable resources must be used prudently to reduce the overall risk to the nation. A systematic approach to this process of asset allocation is to reduce the overall risk and not just an individual element of risk such as vulnerabilities. Hence, we define risk as a function of three variables: the threat (the likelihood and scenario of the terrorist act), the vulnerability (the vulnerability of potential targets to the threat), and the consequences (health and safety, economic, etc.) resulting from a successful terrorist scenario. Both the vulnerability and consequences from a postulated adversary scenario can be reasonably well estimated. However, the threat likelihood and scenarios are much more difficult to estimate. A possible path forward is to develop scenarios for each potential target in question using experts from many disciplines. This should yield a finite but large number of target-scenario pairs. The vulnerabilities and consequences for each are estimated and then ranked relative to one another. The resulting relative risk ranking will have targets near the top of the ranking for which the threat is estimated to be more likely, the vulnerability greatest, and the consequences the most grave. In the absence of perfect intelligence, this may be the best we can do.

Following a terrorist attack on the main Jewish center in the city of Buenos Aires, Argentina, in July 1994, all Jewish institutions (including schools, synagogues, and clubs) were given 24-hour police protection. Thus, this hideous event induced a geographical allocation of police forces that can be presumed to be exogenous in a crime regression. Using data on the location of car thefts before ...

    2016-03-01

    Full Text Available “Talking to terrorists remains a taboo” (Goerzig, 2010: p. 125. The adoption and reinforcement of such a moral position by many Western and non-Western governments alike has played no small role in, to a large extent, states to contain the violence and insecurity bred by terror activist in the post-Cold war and post-9/11 periods. Yet, few policymakers seem to recognize the danger in building political and social environments in which dialogue between states and terrorist groups and organizations is little more than depravity or even a betrayal to entire populations. To be sure, the protection of civilian populations has been entrusted to states that might otherwise learn better means of terrorism deterrence if lines of communication between states and terrorists were less constrained. The taboo of which Carolin Goerzig speaks, is one that “has been institutionalized in a legal framework in which … academics are being asked to report on their students and in which attempting to understand the subjectivities of ‘terrorist’ suspects could be interpreted as a ‘glorification of terrorism’” (Jackson quoted in Goerzig, 2010: p. 125.

    Full Text Available The world financial markets have reacted in a highly consistent pattern to the incident of 9/11 in the United States, suicide blasts at night clubs at Bali in 2002, the Madrid and London train bombings in 2004-2005 and a series of continuous blasts and suicide attacks in Pakistan. In this study, we examined the effect of terrorist attack news on returns and volatility for the Karachi Stock Exchange. We employ the EGARCH model proposed by Engle and Ng (1993as it allows good and bad news to have a different impact on volatility. Our results indicate that terrorist attack news has negative impact on the returns of all the sector indices. However, news of these events increased the volatility of KSE100 index and financial sector index. Further it is concluded that the results of oil and gas, and industry are not statistically significant in response to terrorist attack news, indicating that such type of news does not affect the volatility of these two sectors. Moreover, volatility asymmetry is negative in all of the sectors including KSE100 confirming leverage effect.

    Full Text Available Both domestic and international terrorist organizations employ guerrilla warfare tactics, techniques, and procedures. Thus, the ability to identify and defeat the members of these organizations, cripple their infrastructures, and disrupt their financial resources lies in the understanding of modern guerrilla warfare as it develops in the twenty-first century within the United States.3 The forms of asymmetric warfare4 adopted by domestic and international terrorist groups alike is no longer intended to gain simple media exposure or governmental manipulation; they want to make an overpowering impact by causing massive loss of life and severe damage to infrastructure and are often motivated by religious imperatives and political goals. As terrorism analyst Stephen Flynn has observed, "Throughout the 20th century [Americans] were able to treat national security as essentially an out-of-body experience. When confronted by threats, [America] dealt with them on the turf of our allies or our adversaries. Aside from the occasional disaster and heinous crime, civilian life [in the United States] has been virtually terror-free." With the turn of the twenty-first century, terrorist operations have become more prevalent in the United States and are taking shape in the form of modern guerrilla warfare, thus creating new challenges for federal, state, and local law enforcement agencies. After reviewing the origin and nature of these challenges, this article will offer some suggestions for countering guerilla warfare in the United States.

A representative sample of 2,081 adults completed terrorism perception questions as part of the New South Wales Population Health Survey. Overall, 30.3% thought a terrorist attack in Australia was highly likely, 42.5% were concerned that self or family would be directly affected and 26.4% had changed the way they lived due to potential terrorist attacks. Respondents who spoke a language other than English at home were 2.47 times (Odds Ratios (OR=2.47, 95% CI:1.58-3.64, pterrorism. Those with high psychological distress perceived higher terrorism likelihood and greater concern that self or family would be directly affected (OR=1.84, 95% CI:1.05-3.22, p=0.034). Evacuation willingness was high overall but those with poor self-rated health were significantly less willing to leave their homes during a terrorism emergency. Despite not having experienced recent terrorism within Australia, perceived likelihood of an attack was higher than in comparable western countries. Marginalisation of migrant groups associated with perceived terrorism threat may be evident in the current findings. This baseline data will be useful to monitor changes in population perceptions over time and determine the impact of education and other preparedness initiatives.

    Over the past two decades, the field has witnessed tremendous advances in our understanding of terrorism and its impacts on affected youth. It is now well established that a significant proportion of exposed youth show elevated PTSD symptoms in the months following a terrorist attack. In more recent years, research has expanded beyond confirming our understanding of the association between direct terrorism exposure and child PTSD symptoms by elucidating (a) links between terrorism exposure and non-PTSD clinical outcomes (e.g., externalizing problems, substance use), (b) individual differences associated with divergent patterns of risk and resilience, (c) the clinical correlates of media-based contact with terrorism, (d) clinical outcomes associated with exposure to recurrent terrorist attacks, and (e) exposure to extended contexts of uncertainty and the possibilities of future terrorism. Researchers studying the effects of terrorism and political violence on youth have increasingly examined a much broader range of regions in the world, affording needed opportunities to consider the generalizability of prior findings to youth living in different political contexts, in less developed regions of the world, and/or in regions with different rates of recurrent terrorism. In order to understand and, in turn, best meet the clinical needs of the majority of terrorism-affected youth across the globe, more targeted research on exposed youth is needed in developing regions of the world and regions enduring more recurrent terrorist attacks.

    This article provides an in-depth assessment of lone actor terrorists' attack planning and preparation. A codebook of 198 variables related to different aspects of pre-attack behavior is applied to a sample of 55 lone actor terrorists. Data were drawn from open-source materials and complemented where possible with primary sources. Most lone actors are not highly lethal or surreptitious attackers. They are generally poor at maintaining operational security, leak their motivations and capabilities in numerous ways, and generally do so months and even years before an attack. Moreover, the "loneness" thought to define this type of terrorism is generally absent; most lone actors uphold social ties that are crucial to their adoption and maintenance of the motivation and capability to commit terrorist violence. The results offer concrete input for those working to detect and prevent this form of terrorism and argue for a re-evaluation of the "lone actor" concept. © 2017 The Authors.

    The Internet is a culmination of information age technologies and an agent of change. As with any infrastructure, dependency upon the so-called global information infrastructure creates vulnerabilities. Moreover, unlike physical infrastructures, the Internet is a multi-use technology. While information technologies, such as the Internet, can be utilized as a tool of terror, these same technologies can facilitate the implementation of solutions to mitigate the threat. In this vein, this paper analyzes the multifaceted nature of the Internet information infrastructure and argues that policymakers should concentrate on the solutions it provides rather than the vulnerabilities it creates. Minimizing risks and realizing possibilities in the information age will require institutional activities that translate, exploit and convert information technologies into positive solutions. What follows is a discussion of the Internet information infrastructure as it relates to increasing vulnerabilities and positive potential. The following four applications of the Internet will be addressed: as the infrastructure for information competence; as a terrorist tool; as the terrorist`s target; and as an architecture for rapid response.

    The diagnosis of HSR to iodinated contrast media (ICM) is challenging based on clinical history and skin tests. This study evaluates the negative predictive value (NPV) of skin tests and intravenous provocation test (IPT) with low-dose ICM in patients with suspected immediate hypersensitivity reaction (HSR) to ICM. Thirty-seven patients with suspected immediate hypersensitivity reaction to ICM were included retrospectively. Skin tests and a single-blind placebo-controlled intravenous provocation test (IPT) with low-dose iodinated contrast media (ICM) were performed. Skin tests with ICM were positive in five cases (one skin prick test and five intradermal test). Thirty-six patients were challenged successfully by IPT, and only one patient had a positive challenge result, with a grade I reaction by the Ring and Messmer classification. Ten of 23 patients followed up by telephone were re-exposed to a negative tested ICM during radiologic examination; two experienced a grade I immediate reaction. For immediate hypersensitivity reaction to ICM, the NPV for skin tests and IPT with low dose was 80% (95% CI 44-97%). © 2016 John Wiley & Sons Ltd.

    Full Text Available This study examined the effect of history of harsh parenting on readiness for aggression in young adults testing the mediating effect of emotional reaction to frustration and provocation that is assumed to arise in the context of a history of physical punishment and psychological aggression. Data were collected from 402 participants including 187 Poles (Mage = 9.5; SD = 1.2 and 215 Americans (Mage = 19.16, SD = 1.15. Participants reported retrospectively on corporal punishment and psychological aggression experienced during childhood. Based on self-report instruments, sensitivity to provocation and frustration and three patterns of readiness for aggression in adulthood were assessed. Contrary to the US sample, sensitivity to provocation and frustration were mediators in the Polish sample alone. The important role of contextual factors that define harsh parenting circumstances, such as cultural context and sex of the parent, are discussed.

    Full Text Available The ceasefire of armed activities announced by ETA (Basque Homeland and Freedom in 2011 has fostered a debate about the violence and the victims of the terrorist organization. During those years, the violence perpetrated by ETA was characterized by bomb attacks and assassinations. In addition to this blatant violent behavior, a low-intensity violence was also taking place in the Basque Country, consisting of terrorist threats against their targets. There is, however, a lack of evidence-based research into this phenomenon. This investigation studies the impact of terrorist threats on the psychosocial functioning of people threatened by ETA in the Basque Country. Seventy-six people targeted by ETA completed self-reported survey. Terrorist threats and their derived psychosocial consequences were assessed by this way. The findings point out a relationship between terrorist threats and their psychosocial effects, which greatly affected the immediate environment of the targets too. The implications of these findings are discussed.

    The aim of the study is to compare the glass fibre-based basophil histamine release test with skin test (Phazet), RAST (Phadebas) and bronchial provocation test in children with allergic asthma. The study comprised 68 selected children with a case history of extrinsic allergic asthma to danders (cat and dog) and house-dust mite. Skin prick test, RAST, and histamine release were performed in all children and the bronchial provocation test was used as a reference of "true allergic asthma". A total of 81 allergen bronchial challenges were performed and 44 children experienced 49 positive provocations. In 2.9% (2/68) of the children histamine release could not be performed due to technical difficulties (low histamine release with anti-IgE). Concordances in the range 76-87% were observed with no significant difference between the tests. The highest concordance (87%) was found between histamine release and bronchial provocation test followed by skin prick test vs bronchial provocation (84%) and RAST vs bronchial provocation (80%). The sensitivity and specificity were calculated for each test. All tests showed sensitivities in the range 90-94% and no significant difference between them was observed. The specificity of histamine release, skin prick test, and RAST was 0.78, 0.69, and 0.63, respectively. The specificity of histamine release was better than RAST demonstrated by 95% confidence intervals. In conclusion, it was found that the histamine release test is a convenient diagnostic method and the study indicates a diagnostic value comparable to the common diagnostic methods in clinical allergy.

    To study the effects and significance of methacholine (Mch) bronchial provocation tests and salbutamol bronchial dilation test on measurements of fractional exhaled nitric oxide (FeNO) in patients with asthma. This was a prospective study conducted between November 2014 and August 2015. A total of 135 patients with asthma visiting the respiratory clinic of Zhujiang Hospital were enrolled. The patients received either Mch bronchial provocation test or salbutamol bronchial dilation test based on their FEV1/FVC values and cooperative degree. Mch bronchial provocation test was performed by using Astograph Jupiter-21 (Astograh group) or APS-Pro airway reaction testing apparatus (APS group), and salbutamol bronchial dilation test was performed by using Jaeger spirometer (Dilation group). We compared the differences between FeNO values measured before examinations (Pre-FeNO) and 5 min after completion of these examinations (Post-FeNO). The geometric mean of Pre-FeNO and Post-FeNO was 28.07 ppb and 24.08 ppb respectively in the Astograh group, with a significant decrease of the FeNO value after the examination (Z=-3.093, P=0.002). A significant difference between Pre-FeNO and Post-FeNO was found in patients who had positive provocation results in the Astograh group (Z=-2.787, P=0.005), but not in the patients with negative results (Z=-1.355, P=0.176). The geometric mean of FeNO in the APS group decreased significantly from 27.95 ppb to 23.15 ppb after the examination was completed (Z=-5.170, P=0.000); both in patients with positive saline or Mch provocation results and in patients with negative provocation results, the differences between Pre-FeNO and Post-FeNO in the APS group being significant (Z=-2.705, -3.709, -2.371, P=0.002, 0.000, 0.018). No difference of FeNO change(ΔFeNO) was observed between the 2 Mch bronchial provocation test groups (Ubronchial dilation test has minor effect on the measurement of FeNO, but Mch bronchial provocation tests can significantly

  19. Allergic asthmatics show divergent lipid mediator profiles from healthy controls both at baseline and following birch pollen provocation.

    Directory of Open Access Journals (Sweden)

    Susanna L Lundström

    Full Text Available Asthma is a respiratory tract disorder characterized by airway hyper-reactivity and chronic inflammation. Allergic asthma is associated with the production of allergen-specific IgE and expansion of allergen-specific T-cell populations. Progression of allergic inflammation is driven by T-helper type 2 (Th2 mediators and is associated with alterations in the levels of lipid mediators.Responses of the respiratory system to birch allergen provocation in allergic asthmatics were investigated. Eicosanoids and other oxylipins were quantified in the bronchoalveolar lumen to provide a measure of shifts in lipid mediators associated with allergen challenge in allergic asthmatics.Eighty-seven lipid mediators representing the cyclooxygenase (COX, lipoxygenase (LOX and cytochrome P450 (CYP metabolic pathways were screened via LC-MS/MS following off-line extraction of bronchoalveolar lavage fluid (BALF. Multivariate statistics using OPLS were employed to interrogate acquired oxylipin data in combination with immunological markers.Thirty-two oxylipins were quantified, with baseline asthmatics possessing a different oxylipin profile relative to healthy individuals that became more distinct following allergen provocation. The most prominent differences included 15-LOX-derived ω-3 and ω-6 oxylipins. Shared-and-Unique-Structures (SUS-plot modeling showed a correlation (R(2 = 0.7 between OPLS models for baseline asthmatics (R(2Y[cum] = 0.87, Q(2[cum] = 0.51 and allergen-provoked asthmatics (R(2Y[cum] = 0.95, Q(2[cum] = 0.73, with the majority of quantified lipid mediators and cytokines contributing equally to both groups. Unique structures for allergen provocation included leukotrienes (LTB(4 and 6-trans-LTB(4, CYP-derivatives of linoleic acid (epoxides/diols, and IL-10.Differences in asthmatic relative to healthy profiles suggest a role for 15-LOX products of both ω-6 and ω-3 origin in allergic inflammation. Prominent differences at baseline levels indicate

    Full Text Available Terrorist acts have been a worrisome phenomenon for all nations. Paradoxically, although states have been conscious about the danger of this phenomenon, there is no definition of terrorist acts so far. States have been skeptical and they have not agreed that the judgment of these criminal offences be performed by international jurisdictions, thus opting for the domestic jurisdiction. Nevertheless, states have lacked the willingness to establish joint criminal policies and find efficacious means to combat these terrorist acts. One of these efficacious means has been the seizure and confiscation of licit and illicit assets possessed by terrorist groups. This is the focus of this short study, which will be inclusive by viewing this topic under the general framework of international acts, our domestic legislation, as well as the American one. This paper aims at presenting the legislative measures taken by the Albanian state to meet international requirements. It endeavors to provide arguments why all licit and illicit assets associated with terrorist acts are seized and confiscated. Special attention is paid to the way these assets are administered. Moreover, this study tries to analyze the achievements and problems in Albania, as well as provide conclusions and recommendations.

    Full Text Available Terror in the Twin Towers – dystopia and irony? 9/11 in Darlah and En terrorist i senga. Through globalization of our media society, children as well as adults are endlessly exposed to information and images from all over the world. In Norway, signs of the terrorist attack on the Twin Towers in USA on September 11th 2001 are now to be found in literature for children and young adults. With globalization theory and post-colonial theory I will examine how two novels present global challenges in general and 9/11 in particular. What does globalization mean for the construction of identity? Who are “we”, and who are “the others”? The novel for young adults, Darlah – 172 timer på månen [Darlah – 172 hours on the moon] (2008 by Johan Harstad, is a dystopia where 9/11 points forward to a full scale catastrophe for humanity. En terrorist i senga [There's a terrorist in my bed] (2008, a novel for children by Endre Lund Eriksen, makes explicit references to 9/11 – but with playfulness and ironic revelation of xenophobia. Both books use aliens from outer space as “the other”, but where Darlah presents a pessimistic view of our global future, En terrorist i senga is optimistic on behalf of the humankind.

    In the Allergo-Immunological Centre of Rome University we selected 120 patients of both sexes, ranging from 5-65 years of age, affected by asthma and/or conjunctivitis without past or present history of nasal impairment (itching, sneezing, hydrorrhea). As a result of the allergometric tests carried out, the authors divided the samples into three groups: 1) positive reaction to Dermatophagoides Pteronissimus (66.6%); 2) positive reaction to the Graminacee (28.3%); 3) positive reaction to Parietaria officinalis (5.1%). After having undergone the rhinoreomanometric test of nasal provocation, 50% of the patients revealed a positive reaction to the specific allergen, more specifically at 50 PNU/ml 40% of the case were positive, and at 100 PNU/ml 50% were positive. These results are discussed in the light of modern biological knowledge on the mastocytes in normal subjects and in those suffering from allergy.

  4. Effect of 7 July 2005 terrorist attacks in London on suicide in England and Wales.

    A reduction in suicide in England and Wales has been reported after the attacks of 11 September 2001 in the USA. It may be plausible therefore to expect a much greater impact on suicide in the UK in response to the events of 7 July 2005, caused by the first suicide terrorist attack by Islamic extremists on British soil. To examine the effect of the 7 July 2005 terrorist attacks in London on suicide rates in England and Wales. Analysis of number of suicide (ICD-10 codes X60-X84) and undetermined injury deaths (ICD-10 codes Y10-Y34) reported in England and Wales in the 12 weeks before and after 7 July 2005. We used Shewhart Control Charts based on Poisson rates to explore adjusted daily and weekly suicide rates and rate differences with respect to 7 July 2005. A brief but significant reduction in daily suicide rate was observed a few days after the terrorist attack in London on 7 July 2005. Further reduction was also observed on the 21 July 2005, coinciding with the second wave of attacks. No similar reduction in suicide was seen during the same period in the previous 4 years. Poisson regression models with indicator variables for each day in July 2005 revealed a reduction of 40% of the expected daily rate for these 2 days only. We found no evidence of any longer-term effect on suicide. The study findings are contrary to our expectation and only weakly support Durkheim's theory that periods of national threat lower the suicide rate through the impact on social cohesion. It is possible that previous experience of IRA terrorism in the UK may have limited the effect of the 7 July 2005 attacks on suicide in England and Wales. The shock value of suicide terrorism and its psychological potency appear to diminish over time as the tactic becomes overused.

  5. [And if it happened to children? Adapting medical care during terrorist attacks with multiple pediatric victims].

    In light of the recent terrorist attacks in Europe, we need to reconsider the organization of rescue and medical management and plan for an attack involving multiple pediatric victims. To ensure quick surgical management, but also to minimize risk for on-site teams (direct threats from secondary terrorist attacks targeting deployed emergency services), it is crucial to evacuate patients in a swift but orderly fashion. Children are vulnerable targets in terrorist attacks. Their anatomical and physiological characteristics make it likely that pediatric victims will suffer more brain injuries and require more, often advanced, airway management. Care of multiple pediatric victims would also prove to be a difficult emotional challenge. Civilian medical teams have adapted the military-medicine principles of damage control in their medical practice using the MARCHE algorithm (Massive hemorrhage, Airway, Respiration [breathing], Circulation, Head/Hypothermia, Evacuation). They have also learned to adapt the level of care to the level of safety at the scene. Prehospital damage control principles should now be tailored to the treatment of pediatric patients in extraordinary circumstances. Priorities are given to hemorrhage control and preventing the lethal triad (coagulopathy, hypothermia, and acidosis). Managing hemorrhagic shock involves quickly controlling external bleeding (tourniquets, hemostatic dressing), using small volumes for fluid resuscitation (10-20ml/kg of normal saline), quickly introducing a vasopressor (noradrenaline 0.1μg/kg/min then titrate) after one or two fluid boluses, and using tranexamic acid (15mg/kg over 10min for loading dose, maximum 1g over 10min). Prehospital resources specifically dedicated to children are limited, and it is therefore important that everyone be trained and prepared for a scene with multiple pediatric patients.

    The prevalence and mean provocative dose of oral aspirin (MPDA) triggering respiratory reactions in people with asthma have been inconsistently reported, and the relationship between NSAID-exacerbated respiratory disease (NERD) and asthma morbidity was less well quantified. A systematic review was performed by identifying studies diagnosing NERD using blinded, placebo-controlled oral provocation challenge tests (OPCTs) or by self-reported history in people with asthma. Data were extracted, and effect estimates for changes in respiratory function, MPDA and asthma morbidity were pooled using random-effects meta-analysis. The prevalence of NERD in adults with asthma was 9.0% (95% CI 6-12%) using OPCTs and 9.9% (95% CI 9.4-10.5%) using self-reported history from questionnaires. The MPDA in adults with NERD was 85.8 mg (95% CI 73.9-97.6). In people with NERD, the risk of: uncontrolled asthma was increased twofold (RR 1.96 (95% CI 1.25-3.07)); severe asthma and asthma attacks was increased by 60% (RR 1.58 (95% CI 1.15-2.16) and RR 1.59 (95% CI 1.21-2.09), respectively); emergency room visits was increased by 80% (RR 1.79 (95% CI 1.29-2.49)); and asthma hospitalization was increased by 40% (RR 1.37 (95% CI 1.12-1.67)) compared to people with NSAID-tolerant asthma. Respiratory reactions triggered by oral aspirin in people with asthma are relatively common. At the population level, the prevalence of NERD was similar when measured using appropriately conducted OPCTs or by self-reported history. On average, respiratory reactions were triggered by clinically relevant doses of oral aspirin. Asthma morbidity was significantly increased in people with NERD who potentially require more intensive monitoring and follow-up. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A previous study has demonstrated that symptoms suggestive of dumping syndrome appear after a provocation test early after laparoscopic sleeve gastrectomy (LSG) in 45 % of patients, and these are mainly related to early dumping. The aim of this study is to evaluate the evolution of dumping symptoms during the first postoperative year. Twenty-five non-diabetic morbidly obese patients (6 male, 19 female) were evaluated with an oral glucose tolerance test (OGTT) preoperatively, at 6 weeks and at 6 months postoperatively. In addition, 12 of them repeated the OGTT at 12 months after LSG. Sigstad score was used to separate dumpers from non-dumpers and Arts' questionnaire to differentiate between early and late dumping. Insulin and glucose levels were also measured. Sigstad score remained significantly elevated at 6 and 12 months postoperatively compared to preoperative values. Symptoms suggestive of dumping syndrome were recorded in 40 % of patients at 6 months and in 33 % at 12 months postoperatively. Arts' questionnaire demonstrated that early dumping score remained higher compared to baseline at 6 and 12 months postoperatively. Late dumping scores increased gradually during the time and that difference was statistically significant at 12 months after LSG. Hypoglycaemia occurred at 33 % of patients both at 6 and 12 months postoperatively. Symptoms suggestive of dumping syndrome after provocation still exist at 6 and 12 months in a significant proportion of patients after LSG and include both early and late dumping. These findings are consistent with the high incidence of hypoglycaemia after OGTT at 6 and 12 months after LSG.

  8. FCJ-161 Productive Provocations: Vitriolic Media, Spaces of Protest and Agonistic Outrage in the 2011 England Riots

    Directory of Open Access Journals (Sweden)

    Anthony McCosker

    2013-12-01

    Full Text Available The intense social upheaval that spread through a number of UK cities in the riots and protests of August, 2011 signalled the terrifying speed with which passionate disaffection can turn to uncontained violence. At stake in the dense and volatile debate that ensued, and in the acts of violence themselves, were contests over spaces as well as competing models of democracy, publics and citizenship, including the appropriate use of social media. Within these debates, almost universally, rational deliberative discourse and action is assumed to be the only route to legitimate “civil” society. So what is to be made of the violent physical contest over city squares, streets and property, as well as contests over acts of participation and demonstration played out online through the hundreds of eyewitness videos posted to sites like YouTube and the endless flow of often vitriolic words in blogs, comments spaces and social network sites? This paper uses a video posted to YouTube titled ‘Clapham Junction Speaker (London Riots 2011’ to examine the passion and provocation that flowed beyond the city streets to enliven, intensify and sustain forms of protest and civic engagement. We argue that the aggressive and antagonistic tenor of the Speaker’s twenty minute monologue, the bitter vitriol that flowed through the comments space, and even the act of posting it constitute significant elements of a generative, ‘agonistic’ public, to use Chantal Mouffe’s term, that operates in multiple spaces and outside of the rationalising discourse demanded by mainstream media and government. This paper develops a richer understanding of these spaces of protest, and the concept of provocation central to these events.

    Drug provocation tests (DPTs) are the gold standard in diagnosing nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity; however, only few data about follow-up of patients with negative DPTs are actually available. The aim of this study was to assess patients' behavior in taking NSAIDs again and to evaluate NSAID tolerability after negative allergological workup. This is a follow-up study involving patients evaluated for history of cutaneous reactions (urticaria and or angioedema) after NSAID intake and with negative DPTs with the suspected NSAID. Patients were asked during a phone interview about the intake of NSAIDs, tolerance, or reasons of avoidance. The negative predictive value (NPV) of NSAIDs DPTs was calculated. One hundred eleven of 142 patients were successfully contacted; 46/111 (41.44%) took the same NSAID previously tested with two adverse reactions reported (4.34%). Fifty-three of 111 (47.74%) patients did not take the same NSAID, but 34 of them took at least another strong cyclooxygenase (COX) 1 inhibitor, with 1 adverse reaction (2.94%) and 19 of them took only weak COX-1 inhibitors. Twelve of 111 patients (10.8%) did not take any NSAID. Reasons for drug avoidance were mainly fear of reactions (70.8%) and no need (29.2%). NPV, overall, was 96.97% (95% confidence interval, 91-99%). Although NSAID hypersensitivity diagnosis was ruled out by oral provocation test, the majority of patients with a history of urticaria/angioedema avoided the intake of the tested NSAIDs for fear of new reactions, particularly when strong COX-1 inhibitor NSAIDs were involved. The high NPV value of DPT resulting from this study should reassure NSAID intake.

  10. Individual differences in cognitive reappraisal usage modulate the time course of brain activation during symptom provocation in specific phobia

    Science.gov (United States)

    2013-01-01

    Background Extinction learning is proposed to be one key mechanism of action underlying exposure-based cognitive-behavioral therapy (CBT) in specific phobia. Beyond that, cognitive reappraisal, one important strategy to regulate negative emotions, is a crucial component of CBT interventions, but has been disregarded in previous studies investigating neural change processes in specific phobia. The aim of this study was to investigate the association of individual differences in habitual/dispositional cognitive reappraisal usage and the time course of brain activation during phobic stimulation in specific phobia. Methods Dental phobic patients and healthy control subjects participated in a functional magnetic resonance imaging (fMRI) study whilst being confronted with phobic, disgust, fear and neutral pictures. Individual differences in cognitive reappraisal usage were assessed via a self-report questionnaire and correlated with activation decreases over the course of time. Results Phobic individuals with higher dispositional cognitive reappraisal scores showed a more pronounced activation decline in the right dorsomedial prefrontal cortex (dmPFC) which might be associated with a diminution of explicit cognitive emotion regulation over the course of time. Less decrease of activation in the right ventromedial prefrontal cortex (vmPFC) and the lateral orbitofrontal cortex (lOFC) over time in subjects with higher cognitive reappraisal scores might be related to a stronger automatic regulation of emotions or even emotional relearning. Additionally, phobic subjects compared with healthy controls showed a stronger habituation of the left dmPFC over the course of symptom provocation. Conclusions The results of this study show for the first time that individual differences in cognitive reappraisal usage are associated with the time course of brain activation during symptom provocation in specific phobia. Additionally, the present study gives first indications for the

    The MAOA-uVNTR has been suggested to play a role regarding aggression, however, results are inconsistent. We aimed at further elucidating potential effects of the MAOA-uVNTR on aggressiveness with respect to potential modulators: sex, experimental vs. trait aggressiveness and type of aggressiveness (proactive vs. reactive aggressiveness). We tested 239 healthy young adults (88 men/151 women). Participants were genotyped for the MAOA-uVNTR and performed a modified version of a competitive reaction time task - a commonly used and well established tool to elicit and measure aggressiveness. Furthermore, they completed a self-report scale measuring trait aggressiveness. We found a main effect of MAOA-uVNTR on a measure of reactive aggressiveness for both men and women, whereby the low-activity alleles of the MAOA-uVNTR were associated with substantially increased aggressive reactions (paggressiveness. Measures of proactive aggressiveness or self reports were not associated with the MAOA-uVNTR-genotype. Our data are in line with earlier studies and indicate the MAOA-uVNTR-genotype to be specifically associated with measures of reactive impulsive experimental aggressiveness in healthy men and women. Furthermore the association between the MAOA-uVNTR genotype and aggressive responses increases in a fashion linear to the degree of provocation. This indicates that the low-functional alleles of the MAOA-uVNTR are not associated with increased aggressive behavior per se, but rather with an increased aggressive reactivity to provocation.

  12. Hit or Run: Exploring Aggressive and Avoidant Reactions to Interpersonal Provocation Using a Novel Fight-or-Escape Paradigm (FOE

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Interpersonal provocation presents an approach-avoidance conflict to the provoked person: responding aggressively might yield the joy of retribution, whereas withdrawal can provide safety. Experimental aggression studies typically measure only retaliation intensity, neglecting whether individuals want to confront the provocateur at all. To overcome this shortcoming of previous measures, we developed and validated the Fight-or-Escape paradigm (FOE. The FOE is a competitive reaction time (RT task in which the winner can choose the volume of a sound blast to be directed at his/her opponent. Participants face two ostensible opponents who consistently select either high or low punishments. At the beginning of each trial, subjects are given the chance to avoid the encounter for a limited number of times. In a first experiment (n = 27, all women, we found that fear potentiation (FP of the startle response was related to lower scores in a composite measure of aggression and avoidance against the provoking opponent. In a second experiment (n = 34, 13 men, we altered the paradigm such that participants faced the opponents in alternating rather than in random order. Participants completed the FOE as well as the Dot-Probe Task (DPT and the Approach-Avoidance Task (AAT. Subjects with higher approach bias scores in the AAT avoided the provoking opponent less frequently. Hence, individuals with high threat reactivity and low approach motivation displayed more avoidant responses to provocation, whereas participants high in approach motivation were more likely to engage in aggressive interactions when provoked. The FOE is thus a promising laboratory measure of avoidance and aggression.

  14. Terrorists, Geopolitics and Kenya’s Proposed Border Wall with Somalia

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Addressing border security appears to be a plausible approach for states that suffer from terrorism. Kenya’s border wall is to keep terrorists out of Kenya. Utilizing a comparative approach, this paper explores the efficacy of border walls, particularly Kenya’s wall with Somalia. Findings show that walls rarely accomplish stated goals and have unintended consequences. In Kenya’s case, it may reignite border disputes and separate communities. The success of Kenya’s border wall is low given the high levels of corruption and the fact that walls have been demonstrated to only be as good as the people who guard them.

    This paper will discuss terrorism from the perspective of a terrorist organisation acquiring nuclear material to build weapons and how security of radiological material world wide will minimise the risk of such devices being used. It will discuss the need to improve security at nuclear waste processing and storage sites and the adequacy of current security. It will also discuss the phenomenon of suicide attacks by the bomb carriers and the role of the media in informing and educating the general public of the consequences should such a device containing nuclear material be detonated.

  20. Cyberspace as a new arena for terroristic propaganda: an updated examination.

    Science.gov (United States)

    Minei, Elizabeth; Matusitz, Jonathan

    2012-11-01

    This paper analyzes the role of propaganda use in cyberterrorism. The main premise is that cyberterrorists display various semiotic gestures (e.g., the use of images and Internet videos) to communicate their intents to the public at large. In doing so, they communicate themes-these themes range from hate to anger. Cyberterrorism, then, is a form of theater or spectacle in which terrorists exploit cyberspace to trigger feelings of panic and overreaction in the target population. In many cases, this form of propaganda is the primary means of communication for various cyberterrorist groups to convey their intents. Internet sites also produce numerous opportunities for in-group communication and publicity.

    The effects of modern day terrorism on mental health are not well understood. Described here is a 51-year-old male with no pre-existing mental illness who developed paranoid delusions related to the September 11, 2001, terrorist attacks shortly after they occurred. After about two years of treatment with quetiapine the patient was no longer delusional about terrorism but experienced extensive paranoid delusions about commonly encountered persons, requiring treatment which continues to the current time. Clinicians should be aware of the possible impact of terrorist activities on the mental health of vulnerable individuals.

    To analyze related behaviors of individual preparedness and influencing factors on violent terrorist attacks among undergraduates. A total of 1 800 undergraduates from 5 colleges or universities in Guangzhou were selected, using the stratified cluster method. A questionnaire involving the response to violent terrorist attack behavior was used to assess the individual preparedness behaviors among undergraduates. A self-made questionnaire was applied to collect information on demographic factors, cognitive and preparedness behaviors. The mean score of individual preparedness behavior among undergraduates was 13.49 ± 5.02 while information on seeking behavior was 4.27 ± 1.64, avoidance behavior was 5.97 ± 2.16 and violent terrorist attack response behaviors was 23.73 ± 7.21, with 30.0 percent of undergraduates behaved properly. Significant differences were found in the scores of behaviors on the response to violent terrorist attack with different gender, major they pursue or religious belief (P undergraduates involved in this study. Results from the logistic regression analysis revealed that persons being girls (OR = 1.46, 95% CI: 1.06-2.01), with bigger perceived probability (OR = 1.60, 95% CI: 1.12-2.30), with higher alertness (OR = 3.77, 95% CI: 2.15-6.61), with stronger coping confidence (OR = 0.34, 95% CI: 0.24-0.48) and bigger affective response (OR1 = 3.42, 95% CI: 2.40-4.86; OR2 = 0.23, 95% CI: 0.13-0.41), would present more prominent behavior responses when facing the violent terrorist attack. Individual response behaviors to violent terrorist attacks among undergraduates were relatively ideal. Perceived probability, alertness, coping confidence and affective response appeared to be independent influencing factors related to response behaviors against violent terrorist attack. In colleges and universities, awareness on violent terrorist attacks should be strengthened among undergraduates. Focus should target on psychological education dealing with

    Full Text Available The article discusses the need for inter-agency work to minimize the extremist-terrorist activities in the community. The problem of the psychology of extremism and terrorism are increasingly in the spotlight representatives of various scientific disciplines. First of all, there is no single legal science in all respects understanding of phenomena such as extremism and terrorism, their classification and evaluation, although a number of positive examples in this respect international cooperation is present. According to current data provided by the Investigative Committee of the Russian Federation, the General Prosecutor of the Russian Federation, the Russian Ministry of Internal Affairs, as well as the Moscow Bureau for Human Rights, extremism is a real threat to the national security of the Russian Federation. From the data of law enforcement should be the fact that most of the crimes of extremist and terrorist nature committed by persons of young age, the consciousness of which are susceptible to nationalist propaganda. A significant increase in informal youth movements extremist-nationalist orientation. The problem of expansion of extremism is also relevant for the penitentiary system of modern society. The very fact that a significant number of prisoners serving sentences for extremism and terrorism, illustrates the need for them special psychological and educational work

    Full Text Available The article is devoted to the analysis of phraseological units - neologisms which are associated with such traumatic historical events, as the implementation of terrorist acts. Particular emphasis is placed on the description of English, Russian and French phraseological units that have introduced the memory of the terrorist threat in the XX-XXI centuries.: Eng. That’s so 10th September (lit. today September 10, fig: Do not worry ahead of time about nothing; Rus. мочить в сортире (descriptor: беспощадно расправиться; фр. le prince s’est mari, le m chant est mort, c’est une semaine Walt Disney (lit. prince married the villain died, week Walt Disney; descriptor: Idyll, g n ration Bataclan (lit.

    2017-03-01

    Full Text Available XXI century was marked by the strengthening of globalization and integration processes in whole world. This led to the fact that the international community, especially European countries, faced the number of new threats to the spread of Islamic terrorism, the most urgent of which is the activity of “Islamic State” grouping. In this context it’s important to determine the reasons of intense activity growth of IS and its influence in Europe. The article analyzes the factors, contributing to the spread of terrorism. Also it gives some recommendations, implementation of which, according to the author, could decrease the level of terrorist threat. The purpose of the research is to determine factors of growing influence of “Islamic State” and increasing number of terrorist attacks in European countries. The author concludes that IS problem is a comprehensive threat, to prevent which a number of efforts – both within the European continent and in Middle East – is required. It also requires a systematic approach and a high level of consolidation and coordination within the international community.

    Full Text Available Undeniably mass media have become the primary source of information and communication for the majority of, if not all, members of modern societies. The nature of the information thus communicated and the manner in which it is dispensed through media certainly have a profound influence on people’s perceptions of the world around them. The relation between the media, on one hand, and culture, social life, and politics on the other, is an interesting one in which media fulfills dual functions, reflecting and also shaping issues occurring within these three domains (Bell & Garrett, 1998. In the initial media coverage of the 2011 Norway terrorist attacks, some western media authors, inaccurately and unjustly, held Muslims and Islamic groups as being responsible for the attacks. Using Critical Discourse Analysis (CDA, this study seeks to ascertain how language was manipulated in this coverage of the terrorist attacks in order to give expression to blind prejudice against Islam and Muslims. As findings of the analyses reveal, the tones of allegation in these articles and reports differed dramatically from one article to another ranging from tones of mere suspicion to those of overt accusation. The varying degrees of uncertainty or assertion of the authors’ statements were reflected in the varied linguistic forms and devices used within the discourse.

    A multi-agent project was initiated to review site restoration after a terrorist attack. The objective was to acquire and compile information on all known restoration procedures for buildings, exteriors of buildings, their interior contents, and adjacent areas such as parking lots, lawns and vehicles. All procedures were then tested and validated. Restoration procedures included pickup, neutralization, decontamination, removal and final destruction/deposition of the contaminant, cleaning material and contaminated debris resulting from the terrorist act. This research and development project considered chemical, biological and nuclear contamination with the intent to develop methods to decontaminate and restore buildings after a chemical, biological and radiological (CBR) attack. Ideas were collected from work conducted around the world. The efficacy of best candidates was tested along with all selected chemical target items. The project also involved the preparation of procedures for decontamination and restoration. Ultimately, a tradeoff decision basis will be developed to provide information on abandonment and quarantine versus cleanup. The study revealed that there are several technologies that can be used for the decontamination of structures and equipment after acts of terrorism, however, no one technique will work for all contaminants on all surfaces. The selection of a decontamination method depends on the contaminant, the surface being decontaminated and economic, social and health factors. The amount of waste generated by decontamination is a major feasibility factor. 25 refs., 6 tabs.

  17. Tracking and Analyzing Individual Distress Following Terrorist Attacks Using Social Media Streams.

    Lin, Yu-Ru; Margolin, Drew; Wen, Xidao

    2017-08-01

    Risk research has theorized a number of mechanisms that might trigger, prolong, or potentially alleviate individuals' distress following terrorist attacks. These mechanisms are difficult to examine in a single study, however, because the social conditions of terrorist attacks are difficult to simulate in laboratory experiments and appropriate preattack baselines are difficult to establish with surveys. To address this challenge, we propose the use of computational focus groups and a novel analysis framework to analyze a social media stream that archives user history and location. The approach uses time-stamped behavior to quantify an individual's preattack behavior after an attack has occurred, enabling the assessment of time-specific changes in the intensity and duration of an individual's distress, as well as the assessment of individual and social-level covariates. To exemplify the methodology, we collected over 18 million tweets from 15,509 users located in Paris on November 13, 2015, and measured the degree to which they expressed anxiety, anger, and sadness after the attacks. The analysis resulted in findings that would be difficult to observe through other methods, such as that news media exposure had competing, time-dependent effects on anxiety, and that gender dynamics are complicated by baseline behavior. Opportunities for integrating computational focus group analysis with traditional methods are discussed. © 2017 Society for Risk Analysis.

  18. Mining emotional profiles using e-mail messages for earlier warnings of potential terrorist activities

    Galitsky, Boris; Kovalerchuk, Boris

    2006-04-01

    We develop a software system Text Scanner for Emotional Distress (TSED) for helping to detect email messages which are suspicious of coming from people under strong emotional distress. It has been confirmed by multiple studies that terrorist attackers have experienced a substantial emotional distress at some points before committing a terrorist attack. Therefore, if an individual in emotional distress can be detected on the basis of email texts, some preventive measures can be taken. The proposed detection machinery is based on extraction and classification of emotional profiles from emails. An emotional profile is a formal representation of a sequence of emotional states through a textual discourse where communicative actions are attached to these emotional states. The issues of extraction of emotional profiles from text and reasoning about it are discussed and illustrated. We then develop an inductive machine learning and reasoning framework to relate an emotional profile to the class "Emotional distress" or "No emotional distress", given a training dataset where the class is assigned by an expert. TSED's machine learning is evaluated using the database of structured customer complaints.

    Disruptions in emotion regulation are a transdiagnostic risk factor for psychopathology. However, scant research has examined whether emotion regulation strategies are related to the onset of posttraumatic stress disorder (PTSD) symptoms among youths exposed to trauma. We investigated whether pretrauma emotion regulation strategies prospectively predicted PTSD symptom onset after the 2013 Boston Marathon terrorist attack among adolescents and whether these associations were moderated by the degree of exposure to media coverage of the attack. A sample of 78 Boston-area adolescents (mean age = 16.72 years, 65% female) who previously participated in studies assessing emotion regulation and psychopathology were recruited following the terrorist attack. Within 4 weeks of the attack, we assessed self-reported PTSD symptoms and attack-related media exposure via an online survey. We examined the association of pretrauma emotion regulation strategies with PTSD symptom onset after adjustment for pretrauma internalizing symptoms and violence exposure. Greater pretrauma engagement in rumination predicted onset of PTSD symptoms following the attack. Adolescents who engaged in catastrophizing also had greater PTSD symptoms postattack, but only when exposed to high levels of media coverage of the attacks; the same pattern was observed for adolescents who engaged in low levels of cognitive reappraisal. Engagement in specific emotion regulation strategies prior to a traumatic event predicts the onset of PTSD symptoms among youths exposed to trauma, extending transdiagnostic models of emotion regulation to encompass trauma-related psychopathology in children and adolescents. © 2016 Wiley Periodicals, Inc.

    Mortal remains of the soldiers killed in counter-terrorist operations in Kashmir valley are sent to their home after undergoing mandatory embalming. Injuries on the mortal remains of the soldiers killed in counter terrorist operations between Jan 1999 to Dec 2006 were analysed with respect to the agent, mode of injury, age, rank structure, body parts involved, seasonal variations and changing trends. Fatalities consequent to enemy action across line of control and fatalities of Kargil war were also analysed for comparison. Statistical analysis was done using chi square test for difference in proportions. Over the study period, terrorist induced injuries accounted for 8.16 deaths per thousand troops deployed whereas enemy action from across the line of control accounted for 0.63 deaths per thousand. Terrorist induced fatalities peaked in 2001 and thereafter revealed a declining trend ('p' < 0.001). Fatalities due to enemy action across line of control declined to zero since 25 Nov 2003 consequent to effective ceasefire. Of the total fatalities, 89.5% were killed in action (KIA) while 10.5% died of their wounds after reaching the hospital. Fatality to total injured ratio peaked to 29% in 2001 and than stabilized to about 23%. Mean KIA to total casualty ratio was 21%. The rank structure of the fatalities was officers 8.6%, JCOs 7.3%, and Other Ranks 84.1%. Most of the soldiers died young, 51% being below 25 years of age. Out of the terrorist induced fatalities, 78.2% died of gunshot wounds and 21.5% by splinters and improvised explosive devices (IED). The ratio was reversed in enemy induced fatalities and in Kargil war. Fatalities peaked during June to November and declined in winters. Body region wise, 23.4% of all deaths were due to head injury, 8.4% due to neck and maxillofacial injury, 18.4% due to injury to lungs and 11% due to heart injury. Most frequent target of the fatal bullet was brain (25.4%), closely followed by lungs (22.5%) and heart (12.3%). When

    Provocative pain responses following standardised protocols of repeated sagittal plane spinal bending have not been reported in people with chronic low back pain (CLBP). Potential differing pain responses to movement likely reflect complex sensorimotor interactions influenced by physical, psychological and neurophysiological factors. To date, it is unknown whether provocative pain responses following repeated bending are associated with different pain sensitivity and psychological profiles. Therefore the first aim of this study was to determine whether data-driven subgroups with different, clinically-important pain responses following repeated movement exist in a large CLBP cohort, specifically using a standardised protocol of repeated sagittal plane spinal bending. The second aim was to determine if the resultant pain responses following repeated movement were associated with pain and disability, pain sensitivity and psychological factors. Clinically-important (≥2-points, 11-point numeric rating scale) changes in pain intensity following repeated forward/backward bending were examined. Participants with different provocative pain responses to forward and backward bending were profiled on age, sex, pain sensitivity, psychological variables, pain characteristics and disability. Three groups with differing provocative pain responses following repeated movements were derived: (i) no clinically-important increased pain in either direction (n=144, 49.0%), (ii) increased pain with repeated bending in one direction only (unidirectional, n=112, 38.1%), (iii) increased pain with repeated bending in both directions (bidirectional, n=38, 12.9%). After adjusting for psychological profile, age and sex, for the group with bidirectional pain provocation responses following repeated spinal bending, higher pressure and thermal pain sensitivity were demonstrated, while for the group with no increase in pain, better cognitive and affective psychological questionnaire scores were

    The current study investigates the role of individual and intergroup factors in predicting Muslims’ tendency to attribute domestic terrorism in Indonesia to an external cause (i.e., The West) or an internal cause (i.e., radical Islamist groups). The results (N = 308) showed that intergroup factors of symbolic threat and realistic threat directly increased the external attribution and conversely decreased the internal attribution. Within the context of the current research, symbolic threat refers to Muslims’ perception that the norms and values of the West undermine Islamic identity. Realistic threat denotes Muslims’ perception that the economy and technology of the West undermine Islamic power. The individual factor of Islamic fundamentalism, which has to do with Muslims’ belief in the literal interpretation of and strict guidelines to Islamic doctrines, indirectly predicted both external attribution and internal attribution of terrorism as hypothesized, via the extent to which Muslims perceived the West as posing a symbolic threat, but not a realistic threat to Islamic existence. Uncertainty avoidance, a cultural dimension that describes the extent to which people view clear instructions as a pivotal source of concern to deal with societal problems, also significantly increased perceived symbolic threat and realistic threat, and this cultural dimension mediated the effect of Islamic fundamentalism on each of the intergroup threats. Finally, we found that the level of Islamic fundamentalism was dependent upon cognitive response, but not emotional response to mortality salience. The cognitive response to mortality salience denotes what Muslims are thinking about in coping with their own death whereas the emotional response denotes what Muslims are feeling about such issue. In particular, we found the cognitive response, but not the emotional response to mortality salience significantly gave rise to Muslims’ Islamic fundamentalism. These findings shed light on the importance of combining individual factors and group factors in explicating the dynamics of Muslims’ tendency to make attributions of causes of domestic terrorism. We discuss theoretical implications and study limitations, as well as practical actions policy makers could conduct to deal with Muslims’ Islamic fundamentalism and reduce the extent to which this particular group perceives the West as threatening their existence.

    The current study investigates the role of individual and intergroup factors in predicting Muslims' tendency to attribute domestic terrorism in Indonesia to an external cause (i.e., The West) or an internal cause (i.e., radical Islamist groups). The results (N = 308) showed that intergroup factors of symbolic threat and realistic threat directly increased the external attribution and conversely decreased the internal attribution. Within the context of the current research, symbolic threat refers to Muslims' perception that the norms and values of the West undermine Islamic identity. Realistic threat denotes Muslims' perception that the economy and technology of the West undermine Islamic power. The individual factor of Islamic fundamentalism, which has to do with Muslims' belief in the literal interpretation of and strict guidelines to Islamic doctrines, indirectly predicted both external attribution and internal attribution of terrorism as hypothesized, via the extent to which Muslims perceived the West as posing a symbolic threat, but not a realistic threat to Islamic existence. Uncertainty avoidance, a cultural dimension that describes the extent to which people view clear instructions as a pivotal source of concern to deal with societal problems, also significantly increased perceived symbolic threat and realistic threat, and this cultural dimension mediated the effect of Islamic fundamentalism on each of the intergroup threats. Finally, we found that the level of Islamic fundamentalism was dependent upon cognitive response, but not emotional response to mortality salience. The cognitive response to mortality salience denotes what Muslims are thinking about in coping with their own death whereas the emotional response denotes what Muslims are feeling about such issue. In particular, we found the cognitive response, but not the emotional response to mortality salience significantly gave rise to Muslims' Islamic fundamentalism. These findings shed light on the importance of combining individual factors and group factors in explicating the dynamics of Muslims' tendency to make attributions of causes of domestic terrorism. We discuss theoretical implications and study limitations, as well as practical actions policy makers could conduct to deal with Muslims' Islamic fundamentalism and reduce the extent to which this particular group perceives the West as threatening their existence.

    Mirror-touch synesthesia (MTS) is the conscious experience of tactile sensations induced by seeing someone else touched. This paper considers two different, although not mutually exclusive, theoretical explanations and, in the final section, considers the relation between MTS and other forms of synesthesia and also other kinds of vicarious perception (e.g., contagious yawning). The Threshold Theory explains MTS in terms of hyper-activity within a mirror system for touch and/or pain. This offers a good account for some of the evidence (e.g., from fMRI) but fails to explain the whole pattern (e.g., structural brain differences outside of this system; performance on some tests of social cognition). The Self-Other Theory explains MTS in terms of disturbances in the ability to distinguish the self from others. This can be construed in terms of over-extension of the bodily self in to others, or as difficulties in the control of body-based self-other representations. In this account, MTS is a symptom of a broader cognitive profile. We suggest this meets the criteria for synesthesia, despite the proximal causal mechanisms remaining largely unknown, and that the tendency to localize vicarious sensory experiences distinguishes it from other kinds of seemingly related phenomena (e.g., non-localized affective responses to observing pain).

    To assess and explain the United States' gender wealth gap, we use the Wisconsin Longitudinal Study to examine wealth accumulated by a single cohort over 50 years by gender, by marital status, and limited to the respondents who are their family's best financial reporters. We find large gender wealth gaps between currently married men and women, and between never-married men and women. The never-married accumulate less wealth than the currently married, and there is a marital disruption cost to wealth accumulation. The status-attainment model shows the most power in explaining gender wealth gaps between these groups explaining about one-third to one-half of the gap, followed by the human-capital explanation. In other words, a lifetime of lower earnings for women translates into greatly reduced wealth accumulation. After controlling for the full model, we find that a gender wealth gap remains between married men and women that we speculate may be related to gender differences in investment strategies and selection effects.

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

    2009-03-01

    The potential for biological, chemical, radiological, or nuclear terrorism has been widely acknowledged since the events of September 11, 2001. Terrorists' use of a radiological dispersal device (RDD), or dirty bomb, is considered to be a threat for which Americans must prepare. Occupational health nurses must have the knowledge and skill set to plan for, respond to, and recover from a radiologic event potentially affecting significant numbers of first responders as well as businesses and their workers. This article describes the hazards related to RDDs and provides resources supporting occupational health nurses' roles in such events occurring near or at their workplaces. Occupational health nurses are prepared to assess and treat RDD causalities using current information to identify signs and symptoms of exposed and contaminated RDD victims. Decontamination, treatment, and recovery methods for workers and businesses affected by an RDD event are described.

    The results of the public opinion poll performed in January 2015, just after the terrorist attack on the French satirical weekly magazine Charlie Hebdo and the kosher supermarket in Paris, when 17 people were killed, showed that a significant number of French citizens held conspiratorial beliefs about it (17 %). This gave reason to an alternative analysis of public opinion, presented in this paper. We collected 990 on-line articles mentioning Charlie Hebdo from Le Monde web site (one of the leading French news agencies), and looked at the ones that contained words related with conspiracy (in French: `complot', `conspiration' or `conjuration'). Then we analyzed the readers response, performing a semantic analysis of the 16490 comments posted on-line as reaction to the above articles. We identified 2 attempts to launch a conspiratorial rumour. A more recent Le Monde article, which reflects on those early conspiratorial attempts from a rational perspective, and the commentary thereon, showed that the readers hav...

    Full Text Available In nowadays Europe a wind of terror of an intensity comparable to that of the belligerent periods walks freely and occasionally strikes the apparent tranquility of our lives. Islamic fundamentalist attacks seemingly coming from nowhere without prior psychological preparation manage to create hardly measurable effects. Media and consequently public opinion resonate dramatically to a reality that is destabilizing the social political economic cultural individual or group balance in many parts of this bewildered and concerned Europe. It is a tense context in which fear and terror annihilate rationality and freedom of expression being able to maintain a toxic atmosphere of information and independent media can serve conjecturally unintentionally even to the harmful interests of those terrorist groups.

  9. War on Terror: Fantasy and Fiction Behind the Mythology of Terrorist Financing

    Directory of Open Access Journals (Sweden)

    El-Fatih A. Abdel Salam

    2009-06-01

    Full Text Available Documentary evidence shows that the series of financial crackdowns initiated since 9/11 have had virtually no impact on terrorism. This is because these efforts are based on a fundamental misconception on how terrorism works. The financial warriors’ predisposition to stereotypes about “Arabs and their money” allowed unsubstantiated rumours–such as Bin Laden’s personal fortune of $300 million–to become established as facts. This study exposes the extent to which Washington policymakers simply transposed the template for the war on drugs on to the war on terror, despite the fact that terrorism is not a profit–driven enterprise. The collateral damage inflicted on organisations like Al-Barakaat, the Somali remittance network, wrongly accused of channeling money to the terrorists, and others are counter-productive as they dent the image of the US in the Muslim world.

  10. Transgression médiatique et provocations décadentes: La décadence comme comportement médiatique.

    Directory of Open Access Journals (Sweden)

    Yoan Vérilhac

    2012-03-01

    Full Text Available The decadent and symbolist movements are deeply connected to the creation of media: newspapers, small reviews which make the promotion of the young poets and their original works. In the 1880’s, the decadent reviews use in a provocative way the codes and the media potentialities. However this provocative press is based on a double language (especially about the relationship with the public, and this contradiction generates a negative image in the popular press: the new generation of poets and writers appears to be a noisy group of « hoaxers ». Therefore, around 1890, when the new reviews grouped around the « symbolist » label define themselves a media identity, it is important for them to distance from decadent behaviours. The decadent moment of the mediatization of literature is thus indispensable to understand the history of connections between press and poetic avant-gardes.

    Patients with allergic rhinitis (AR) feature both allergic airway inflammation and a hyperresponsiveness to nonspecific stimuli which is partly neuronally controlled. Still, it is unclear whether or not neurotrophins are involved in airway pathophysiology of AR and in nasobronchial interaction. Nine AR patients with mono-allergy to grass pollen and nine healthy controls underwent nasal allergen provocation (NP). Serum samples, nasal and bronchial biopsies were taken before (T(0)) and 24 h after (T(24)) NP. Pan-neurotrophin receptor p75(NTR), tyrosine kinase A (trkA), trkB, nerve growth factor (NGF), and brain-derived neurotrophic factor (BDNF) were assessed with immunohistochemistry, and NGF and BDNF levels with ELISA. At T(24), BDNF and NGF were upregulated in nasal mucosa (P neurotrophins and receptors in bronchial mucosa. This study shows that neurotrophins and their receptors are expressed in human airways. Allergic rhinitis was characterized by a modulation of BDNF, NGF, and trkB in nasal mucosa after NP and a correlation of nasal BDNF with the maximal increase of total nasal symptom score. Therefore, our data suggest that neurotrophins participate in upper-airway pathophysiology in AR, whereas their role in nasobronchial interaction remains unclear.

    2012-06-30

    Distressing symptom-related anxiety is difficult to study in obsessive-compulsive disorder (OCD) due to the disorder's heterogeneity. Our aim was to develop and validate a set of pictures and films comprising a variety of prominent OCD triggers that can be used for individually tailored symptom provocation in experimental studies. In a two-staged production procedure a large pool of OCD triggers and neutral contents was produced and preselected by three psychotherapists specialized in OCD. A sample of 13 OCD patients and 13 controls rated their anxiety, aversiveness and arousal during exposure to OCD-relevant, aversive and neutral control stimuli. Our findings demonstrate differences between the responses of patients and controls to OCD triggers only. Symptom-related anxiety was stronger in response to dynamic compared with static OCD-relevant stimuli. Due to the small number of 13 patients included in the study, only tentative conclusions can be drawn and this study merely provides a first step of validation. These standardized sets constitute valuable tools that can be used in experimental studies on the brain correlates of OCD symptoms and for the study of therapeutic interventions in order to contribute to future developments in the field.

    2012-10-01

    A new head exposure system for double-blind provocation studies investigating possible effects of terrestrial trunked radio (TETRA)-like exposure (385 MHz) on central nervous processes was developed and dosimetrically analyzed. The exposure system allows localized exposure in the temporal brain, similar to the case of operating a TETRA handset at the ear. The system and antenna concept enables exposure during wake and sleep states while an electroencephalogram (EEG) is recorded. The dosimetric assessment and uncertainty analysis yield high efficiency of 14 W/kg per Watt of accepted antenna input power due to an optimized antenna directly worn on the subject's head. Beside sham exposure, high and low exposure at 6 and 1.5 W/kg (in terms of maxSAR10g in the head) were implemented. Double-blind control and monitoring of exposure is enabled by easy-to-use control software. Exposure uncertainty was rigorously evaluated using finite-difference time-domain (FDTD)-based computations, taking into account anatomical differences of the head, the physiological range of the dielectric tissue properties including effects of sweating on the antenna, possible influences of the EEG electrodes and cables, variations in antenna input reflection coefficients, and effects on the specific absorption rate (SAR) distribution due to unavoidable small variations in the antenna position. This analysis yielded a reasonable uncertainty of analysis. Copyright © 2012 Wiley Periodicals, Inc.

    1986-10-01

    The effect of intranasal administration of levocabastine, a new selective H1-receptor antagonist, was investigated in a nasal provocation test (NPT) performed with allergens. The NPT allowed a quantitative estimation of the nasal allergic threshold (concentration of allergen necessary to trigger the reaction). In addition, the intensity of the three major rhinitis symptoms (obstruction, rhinorrhea and sneezing) was determined. Twelve adult patients, allergic to grass pollen, underwent a first NPT without pretreatment ('initial NPT'); the NPT was then repeated after the single intranasal administration of either placebo, 8 mg disodium cromoglycate (DSCG) or 0.2 mg levocabastine in a double-blind random order. The NPTs gave reproducible results since both the threshold and symptom intensities were similar in the initial NPT and in the NPT performed after placebo. The reaction threshold increased in 8/12 patients after DSCG (0.05 less than P less than 0.1) and in 9/12 patients after levocabastine (P less than 0.05). Levocabastine clearly inhibited rhinorrhea (P less than 0.001) and sneezing (P less than 0.02) but did not influence the nasal obstruction. DSCG inhibited rhinorrhea only (P less than 0.01). The intranasal administration of levocabastine might be useful in the treatment of allergic rhinitis.

    Kaczmarski, M

    Provocation test (re-introduction of the noxious protein) was carried out in two groups of patients: (a) with intolerance to the cow-milk proteins (41 children) treated with milk-free diet for 6-24 months, and (b) with gluten intolerance (26 children) treated with gluten-free diet for 6-36 months. The following parameters were compared: type and frequency of the clinical symptoms seen in these patients prior to the introduction of allergen-free diet. Moreover, the type of observed morphological changes in the small intestine mucosa following provocation test were analysed in the groups of 7 patients. A two-year elimination of milk from the diet produces milk tolerance in about 61% patients; clinical symptoms in the remaining children are diversified. Re-introduction of gluten with the diet (provocation test) produces recurrence of gluten intolerance in 96% of children treated with gluten-free diet for 2-3 years. Recurrence of the disease was accompanied by the atrophy of the intestinal villi.

    Various provocative maneuvers for diagnosing extensor carpi ulnaris (ECU) tendinitis have been reported; however, it remains unclear which maneuver is the most sensitive to detect ECU tendinitis. To clarify this, we investigated and compared the extratendinous pressure and ECU tendon strain in the sixth extensor compartment of the wrist during various provocative maneuvers for diagnosing ECU tendinitis. Nine upper extremities from nine fresh-frozen cadavers were examined. We investigated extratendinous pressure in the ECU fibro-osseous tunnel of the distal ulna and ECU tendon strain during eight forearm positions-neutral rotation, pronation, supination, pronation with wrist flexion, supination with wrist flexion, supination with wrist extension, both hand and forearm supination, and supination with ECU full loading-to simulate provocative maneuvers reported to detect ECU tendinitis. Pressure was significantly higher during both hand and forearm supination (carpal supination test) and during supination with wrist extension (prayer's hand supination test) than during neutral rotation. The pressure during the carpal supination test was 3 times higher than that during the prayer's hand supination test and 27 times higher than that during the neutral position. Strain was significantly higher during the carpal supination test and during supination with ECU full loading (the ECU synergy test) than during other maneuvers. Both pressure and tendon strain increased most notably during the carpal supination test compared to the other maneuvers, which suggests that the carpal supination test is the most sensitive for the detection of ECU tendinitis.

  17. What explains consciousness? Or…What consciousness explains?

    2014-01-01

    In this invited commentary I focus on the topic addressed in three papers: De Sousa's (2013[1617]) Toward an Integrative Theory of Consciousness, a monograph with Parts 1 & 2, as well as commentaries by Pereira (2013a[59]) and Hirstein (2013[42]). All three are impressively scholarly and can stand-and shout-on their own. But theory of consciousness? My aim is to slice that topic into the two fundamentally different kinds of theories of consciousness, say what appears to be an ideology, out of behaviourism into cognitivism, now also influencing the quest for an "explanation of consciousness" in cognitive neuroscience. I will then say what can be expected given what we know of the complexity of brain structure, the richness of a conscious "vocabulary", and current technological limits of brain imaging. This will then turn to the strategy for examining "what consciousness explains"-metatheory, theories, mappings, and a methodology of competitive support, a methodology especially important where there are competing commitments. There are also increasingly common identifications of methodological bias in, along with failures to replicate, studies reporting unconscious controls in decision, social priming-as there have been in perception, learning, problem solving, etc. The literature critique has provided evidence taken as reducing, and in some cases eliminating, a role for conscious controls-a position consistent with that ideology out of behaviourism into cognitivism. It is an ideological position that fails to recognize the fundamental distinction between theoretical and metaphysical assertions.

    Background: Obsessive-compulsive disorder (OCD) is increasingly being viewed as a multidimensional heterogeneous disorder caused due to the dysfunction of several closely related, overlapping frontostriatal circuits. A study investigating the dimensional construct in treatment naïve, co-morbidity free patients with identical handedness is likely to provide the necessary homogeneity and power to elicit neural correlates of the various symptom dimensions, and overcome the limitations of previous studies. Materials and Methods: Nine DSM-IV OCD patients with predominant contamination-related obsessive-compulsive symptoms (age=29.8±7.1 years; five males: four females; years-of-education=13.9±1.6, YBOCS total score=28.8±4.7, DYBOCS Contamination dimension score=10.7±1.8) and nine healthy controls matched one to one with the patients for age, sex, and years of education (age=27.8±5.4, five males: four females; years-of-education=14.9±3.0), were examined during symptom provocation task performance in 3TMRI. Paired samples t test of brain activation differences (contamination relevant pictures – neutral pictures), limited to apriori regions of interest was done using SPM8 (uncorrected P<0.005). Results: Patients found significantly more pictures to be anxiety provoking in comparison to healthy controls. Patients were found to have deficient activation in the following areas in comparison with healthy controls: bilateral anterior prefrontal, dorsolateral prefrontal, orbitofrontal, anterior cingulate, insular and parietal cortices, precuneus, and caudate. Conclusions: Results underscore the importance of frontal, striatal, parietal, and occipital areas in the pathophysiology of OCD. Divergence of findings from previous studies might be attributed to the absence of confounding factors in the current study and may be due to production of intense anxiety in patients. PMID:23833345

    Isoprostanes are bioactive compounds formed by non-enzymatic oxidation of polyunsaturated fatty acids, mostly arachidonic, and markers of free radical generation during inflammation. In aspirin exacerbated respiratory disease (AERD), asthmatic symptoms are precipitated by ingestion of non-steroid anti-inflammatory drugs capable for pharmacologic inhibition of cyclooxygenase-1 isoenzyme. We investigated whether aspirin-provoked bronchoconstriction is accompanied by changes of isoprostanes in exhaled breath condensate (EBC). EBC was collected from 28 AERD subjects and 25 aspirin-tolerant asthmatics before and after inhalatory aspirin challenge. Concentrations of 8-iso-PGF2α, 8-iso-PGE2, and prostaglandin E2 were measured using gas chromatography/mass spectrometry. Leukotriene E4 was measured by immunoassay in urine samples collected before and after the challenge. Before the challenge, exhaled 8-iso-PGF2α, 8-iso-PGE2, and PGE2 levels did not differ between the study groups. 8-iso-PGE2 level increased in AERD group only (p=0.014) as a result of the aspirin challenge. Urinary LTE4 was elevated in AERD, both in baseline and post-challenge samples. Post-challenge airways 8-iso-PGE2 correlated positively with urinary LTE4 level (p=0.046), whereas it correlated negatively with the provocative dose of aspirin (p=0.027). A significant increase of exhaled 8-iso-PGE2 after inhalatory challenge with aspirin was selective and not present for the other isoprostane measured. This is a novel finding in AERD, suggesting that inhibition of cyclooxygenase may elicit 8-iso-PGE2 production in a specific mechanism, contributing to bronchoconstriction and systemic overproduction of cysteinyl leukotrienes.

    There is information about the impact of disasters and trauma on children, but little is known about the effects of terrorism particularly in India. (i) To assess the knowledge of the 9/11 terrorist attacks to the school going adolescents of India who were miles away from the actual incident. (ii) To compare the reactions to this event among the boys and girls. The study used a survey design with a self-report questionnaire administered to 406 students in 6 schools of standards 9-12. The questionnaire was administered within 3 weeks of occurrence of this event. The mean age of the subjects was 16.34 years (SD= 1.22; range= 13-20) and 44.1% were boys. All the students were aware about this event. Awareness that the twin towers were hit was in 81.06 but only 51.94% knew that Pentagon was also hit. All the children knew who the prime suspect was although only 12.62% were aware about the country to which he belonged. The source of knowledge of the events was the television in 74.7% of the adolescents and 17.95% of them viewed foreign news channels additionally to the Indian channels to gather details about the event. Newspaper, radio and internet were the sources of information in 44.17%, 3.4% and 3.5% children respectively. Of the adolescents who gathered information from the television, 84.7% agreed that there had been an increase in their TV viewing time since the event and it was more than one hour per day in 47.5% of them. None of the students supported the terrorist attacks. The number of students with negative stressors was significantly more than the ones who were unaffected (p 0.0001). The girls were significantly more affected than the boys and while the former expressed anger the latter were more fearful and sad. (p 0.05) The idea of USA going for war against Afghanistan was supported by 69.4% and one third of them believed that such an event might adversely affect India. The adolescents who had witnessed the events on television were more fearful and

    Report is devoted to numerical research of dual-purpose unified cask (used for SFA transportation and storage) resistance to terrorist attacks. High resistance of dual-purpose unified cask has been achieved due to the unique design-technological solutions and implementation of depleted uranium in cask construction. In suggested variant of construction depleted uranium fulfils functions of shielding and constructional material. It is used both in metallic and cermet form (basing on steel and depleted uranium dioxide). Implementation of depleted uranium in cask construction allows maximal load in existing overall dimensions of the cask. At the same time: 1) all safety requirements (IAEA) are met, 2) dual-purpose cask with SFA has high resistance to terrorist attacks.

SecMe increase the level of security but cause interferences and restrictions for customers (e.g. privacy). This study identifies the interferences and analyzes the acceptance with an empirical survey of customers. A composite indicator for the acceptance of different SecMe is developed and integrated into a risk management framework for multi-criteria decision analysis achieving the right balance of risk reduction, costs, and social acceptance.

  7. The spectrum of human reactions to terrorist attacks with weapons of mass destruction: early management considerations.

    Residents of a community who are intentionally exposed to a hazardous biological, chemical, or radiological agent (including medical first-responders and other civil defense personnel who live in that community) will exhibit a spectrum of psychological reactions that will impact the management of the incident. These reactions will range from a variety of behaviors of normal people under abnormal circumstances that either will help or hinder efforts to contain the threatening agent, deliver medical care, and reduce the morbidity, mortality, and costs associated with the disaster, to the development of new, or exacerbation of preexisting, mental disorders. Anticipating the decisions that people will make and actions they will take as the crisis develops is hindered by the limited number of previous disasters that bear crucial similarities to a terrorist attack with a weapon of mass destruction. Such actions, therefore, could serve as models to predict community reactions. One result of a study that attempted to fill in these gaps suggested that medical first-responders and their spouses/significant others may require separately crafted information and advice to reduce the potential for disharmony within the family that could affect job performance during the crisis. For those persons who exhibit emotional lability or cognitive deficits, evaluation of their psychiatric signs and symptoms may be more difficult than imagined, especially with exposure to nerve agents. Appreciation of these difficulties, and possession of the skill to sort through them, will be required of those assigned to triage stations. The allocation and utilization of mental health resources as the incident unfolds will be the responsibility of local consequence managers; these managers should be aware of the results of a recently-held workshop that attempted to reach consensus among experts in disaster mental health, based on the peer-reviewed literature, on the efficacy and safety of various

    Full Text Available Unlike other European countries, Austria has so far been spared from terrorist attacks in the context of radical Islamism. However, the perceived threat, several criminal cases of terrorist involvement as well as being indirectly affected by attacks in other countries led to a high level of public and governmental attention to the issues of radicalisation, terrorist involvement and deradicalisation in Austria. Due to strong public pressure and growing recognition of the existing problem and hazard areas by governmental and non-governmental actors, a number of (1 initiatives providing support and counselling in case of radicalisation have been launched (e.g. Extremism Information Centre; DERAD or extended. Furthermore, (2 governmental agencies and political stakeholders have been pushing for enhanced means for the criminal prosecution and conviction of criminal offenses in the context of terrorism. The article presents an overview and review of new and renewed initiatives as well as (planned policy changes countering radicalisation and deradicalisation and terrorist involvement (support of terrorist organisations, membership, plans for terrorist attacks, etc. and thus a summarising insight into the case of Austria.

    2011-09-01

    The 9/11 terrorist attacks have had profound effect on U.S. domestic and foreign security policy, leading to several expensive wars and the erosion of civil liberties (under the USA PATRIOT Act). We review evidence on political reactions to the 9/11 attacks and conclude that subjective reactions to terrorism played an important role in shaping support for national security policy in the wake of 9/11. Support for a strong national security policy was most pronounced among Americans who perceived the nation as at threat from terrorism and felt angry at terrorists. In contrast, Americans who were personally affected by the attacks were more likely to feel anxious about terrorism, and this anxiety translated into less support for overseas military action. In addition, Americans who felt insecure after the 9/11 attacks and perceived a high future threat of terrorism were more likely than others to support strong foreign and domestic national security policies. Overall, research on American political reactions to 9/11 suggests that support for a strong government response to terrorism is most likely when members of a population perceive a high risk of future terrorism and feel angry at terrorists. © 2011 American Psychological Association

Second, the effects of symbolic, realistic, and terroristic (safety threats on Islamophobia were analyzed concurrently. Finally, within the framework of the revised Integrated Threat Theory (Stephan & Renfro, 2002, and in order to test the mediating effect of threats, SDO is tested as an antecedent of perceived threat and Islamophobia. Respondents from Berlin (N = 355 participated in an online survey. The results indicate that Islamophobia empirically constitutes a two-dimensional phenomenon, consisting of anti-Muslim and anti-Islam sentiment. Whereas symbolic threat is related to both types of Islamophobia, realistic threat is associated only with anti-Muslim prejudice, and terroristic threat is associated only with anti-Islam sentiment. Finally, the results indicate that the relationship between SDO and both dimensions of Islamophobia is mediated by threats. Symbolic threats mediate the relationships between SDO and both dimensions of Islamophobia. Realistic threats mediate the relationship between SDO and anti-Muslim prejudice and terroristic threats between SDO and anti-Islam sentiment.

  14. Some limitations of "Risk = Threat x Vulnerability x Consequence" for risk analysis of terrorist attacks.

    Science.gov (United States)

    Cox, Louis Anthony Tony

    2008-12-01

    Several important risk analysis methods now used in setting priorities for protecting U.S. infrastructures against terrorist attacks are based on the formula: Risk = Threat x Vulnerability x Consequence. This article identifies potential limitations in such methods that can undermine their ability to guide resource allocations to effectively optimize risk reductions. After considering specific examples for the Risk Analysis and Management for Critical Asset Protection (RAMCAP) framework used by the Department of Homeland Security, we address more fundamental limitations of the product formula. These include its failure to adjust for correlations among its components, nonadditivity of risks estimated using the formula, inability to use risk-scoring results to optimally allocate defensive resources, and intrinsic subjectivity and ambiguity of Threat, Vulnerability, and Consequence numbers. Trying to directly assess probabilities for the actions of intelligent antagonists instead of modeling how they adaptively pursue their goals in light of available information and experience can produce ambiguous or mistaken risk estimates. Recent work demonstrates that two-level (or few-level) hierarchical optimization models can provide a useful alternative to Risk = Threat x Vulnerability x Consequence scoring rules, and also to probabilistic risk assessment (PRA) techniques that ignore rational planning and adaptation. In such two-level optimization models, defender predicts attacker's best response to defender's own actions, and then chooses his or her own actions taking into account these best responses. Such models appear valuable as practical approaches to antiterrorism risk analysis.

    Full Text Available Conceived in the late thirties as “bold humanist response to Depression-era fears of runaway scientific advance and soulless industrialism” (Morrison 2012, 6, the superhero has flourished as one of the most resilient archetypes of American popular culture. This essay analyses the literary and cultural contaminations that have engendered an unprecedented revision of the paradigm since the 1980s. In particular, it will take into account three graphic novels by American cartoonist Frank Miller (1957 - , one of leading figures of the mainstream comics renaissance, whose ideas have indelibly influenced the artistic development of both medium and genre. The Dark Knight Returns (1986, The Dark Knight Strikes Again (2002 and Holy Terror (2011 constitute an ideal Batman trilogy that charts the character’s evolution as political counterpoint to the perceived crisis of American identity. In this regard, Reaganism and 9/11 are polarized as historical discontinuities triggering the need for a new kind of a criminal (superhero. It will be in fact demonstrated how the novels hybridise the latent generic links to hardboiled pulp novels (R. Chandler, D.

    2012-01-01

    Clinical work and research relative to child mental health during and following disaster are especially challenging due to the complex child maturational processes and family and social contexts of children’s lives. The effects of disasters and terrorist events on children and adolescents necessitate diligent and responsible preparation and implementation of research endeavors. Disasters present numerous practical and methodological barriers that may influence the selection of participants, timing of assessments, and constructs being investigated. This article describes an efficient approach to guide both novice and experienced researchers as they prepare to conduct disaster research involving children. The approach is based on five fundamental research questions: “Why?, Who?, When?, What?, and How?” Addressing each of the “four Ws” will assist researchers in determining “How” to construct and implement a study from start to finish. A simple diagram of the five questions guides the reader through the components involved in studying children’s reactions to disasters. The use of this approach is illustrated with examples from disaster mental health studies in children, thus simultaneously providing a review of the literature. PMID:23034149

    Being socially integrated is regarded as a protective factor enabling people to cope with adversity. The stress-buffering effect reflects an interaction between stress and a social coping resource factor on subsequent outcomes. This study, based on 2943 police officers, examines mental health outcomes among officers who responded to the 9/11 terrorist attack on the World Trade Center. The Wave 1 data collection took place between September 2003 and November 2004 with a follow-up study (Wave 2) conducted from November 2006 through December 2007. A moderated mediation model was specified that uses event exposure as a distal predictor, earlier stress response as a mediator, and later stress response as an outcome, and social integration as a moderator of this relationship. The mediation hypothesis was confirmed, and moderation occurred at two stages. First, there was a multiplicative relationship between exposure levels and social integration: The higher the exposure level, the more stress responses occur, but this effect was buffered by a high level of social integration. Second, Wave 1 stress interacted with social integration on Wave 2 stress: The more the police officers were socially integrated, the lower the Wave 2 stress, which happened in a synergistic manner. The findings contribute to the understanding of mediating and moderating mechanisms that result in health outcomes such as posttraumatic stress disorder or resilience.

    2010-08-01

    Research published in the aftermath of the 9/11 terrorist attack reported elevated rates of posttraumatic stress disorder (PTSD) in the US population (4.3%-17.0%), attributable to indirect exposure through the media. We use data from a national survey conducted in 2004 to 2005 (National Epidemiologic Survey on Alcohol and Related Conditions Wave 2) (n = 34,653). The list of traumatic events covered in the survey included indirect exposure to 9/11 through media coverage. Respondents who endorsed more than 1 traumatic event were asked to single out "the worst event" they had ever experienced. The worst event (or the only event) was the index event for diagnosing PTSD. Indirect experience of 9/11 had the lowest PTSD risk of all the traumatic events in the list, 1.3%. In the subset that endorsed only 9/11 indirect exposure (n = 3981), the PTSD risk was 0.3%. Of the total sample, 0.7% experienced PTSD in relation to indirect 9/11. Explanations for the lower estimates are discussed.

    Background Context Controversy remains over the use of provocative discography in conjunction with computed tomography (CT) to locate symptomatic intervertebral discs in patients with chronic, low back pain (LBP). The current study explores the relationship between discogenic pain and disc morphology using discography and CT, respectively, and investigates the efficacy of this combined method in identifying surgical candidates for lumbar fusion by evaluating outcomes. Methods 43 consecutive patients between 2006 and 2013 who presented with refractory low back pain and underwent discography and CT were enrolled in the study. For this study, "refractory LBP" was defined as pain symptoms that persisted or worsened after 6 months of non-operative treatments. Concordant pain was defined as discography-provoked LBP of similar character and location with an intensity of ≥ 8/10. Fusion candidates demonstrated positive-level discography and concordant annular tears on CT at no more than two contiguous levels, and at least one negative control disc with intact annulus. Surgical outcomes were statistically analyzed using Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Short Form-36 (SF-36) for back-related pain and disability preoperatively, and 2 weeks, 3, 6, 12, and 24 months postoperatively. Results Annular tears were found in 87 discs. Concordant pain was reported by 9 (20.9%) patients at L3-L4, 21 (50.0%) at L4-L5, and 34 (82.9%) at L5-S1; pain occurred significantly more often in discs with annular tears than those without (plumbar fusion at L3-L4 (n=1(6%)), L4-L5 (n=6 (33%)), L5-S1 (n=5 (28%)), and two-level L4-S1 (n=6 (33%)) via a minimally invasive transforaminal lumbar interbody fusion (MITLIF) approach with the aim to replace the nucleus pulposus with bone graft material. Median follow-up time was 18 months (range: 12-78 months). VAS, ODI, and SF-36 scores demonstrated significant improvements at 10 out of 12 postoperative time points compared

    Secretin-stimulated magnetic resonance cholangiopancreatography (MRCP) is used for the diagnosis of sphincter of Oddi dysfunction (SOD), but it does not correlate well with sphincter of Oddi manometry. Serial MRCP following morphine-neostigmine provocation may be of value in the assessment of SOD, but the effects of these pharmacological agents on pancreaticobiliary morphology in healthy subjects have not been studied. The aim of the present study was to use serial MRCP to characterize the effects of morphine-neostigmine and secretin provocation on serum pancreatic enzyme responses and pancreaticobiliary ductal morphology in healthy subjects. Following a baseline scan and serum lipase and amylase assays, 10 healthy subjects were randomized in a double-blind manner to receive morphine (10 mg intramuscularly [IM]), neostigmine (1 mg IM) and saline (intravenously [IV]); OR saline (IM), saline (IM) and secretin (1 U/kg IV). A MRCP study was performed at 5, 30, 60, 90, 120, 150, and 180 min thereafter, with blood samples taken every 60 min for 4 h. Pancreatic duct (PD) diameter, visible PD length, common bile duct (CBD) diameter, and gallbladder volume were recorded. Crossover studies were performed 10 days later. Serum pancreatic enzyme concentrations were significantly greater (amylase, P = 0.003; lipase, P = 0.04) after morphine-neostigmine than after secretin. Following morphine-neostigmine and secretin provocation, the mean (SEM) percentage increase in PD diameter was 28.7 (7.2) versus 12.9 (3.3); P < 0.0001, and visible PD length was 49.4 (11.5) versus 28.1 (8.2); P < 0.0001, respectively. The effects of morphine-neostigmine were more pronounced than those of secretin in healthy subjects. The diagnostic utility of morphine-neostigmine stimulated serial MRCP for SOD merits further evaluation.

    Pain drawings (PD) are frequently used in research to illustrate the pain response to pain provocation tests. However, there is a lack of data on the reliability in defining the extent and location of pain. We investigated the test-retest reliability in reporting an acute painful sensation induced by a pain provocation test using a novel approach for PD acquisition and analysis in healthy volunteers. Forty healthy volunteers participated. Each participant underwent 2 upper limb neurodynamic tests 1 (ULNT1), once to the point of pain onset (PO) and once until the point of submaximal pain (SP). After each ULNT1, participants completed 2 consecutive PD with an interval of 1 minute. Custom software was used to quantify the pain extent and analyze the pain overlap. The test-retest reliability of pain extent was examined using Intraclass Correlation Coefficient (ICC 2,1 ) and Bland-Altman plots. Pain location reliability was examined using the Jaccard similarity coefficient (JSC). The ICC values for PO and SP were 0.98 (95% CI: 0.96-0.99) and 0.97 (95% CI: 0.95-0.98), respectively. The mean difference and 95% limits of agreement (± 1.96 SD) in the Bland-Altman plots were 14 pixels (-1080;1110) for PO, and 145 (-1610;1900) for SP. The median JSCs (Q1;Q3) were 0.73 (0.64;0.80) for PO and 0.76 (0.65;0.79) for SP. Pain drawings is a reliable instrument to investigate pain extent and pain location in healthy individuals experiencing an acute painful sensation induced by a pain provocation test. © 2016 World Institute of Pain.

  2. The counter-terrorist campus: Securitisation theory and university securitisation – Three Models

    Full Text Available With intensified threats to global security from international terrorism, universities have become a focus for security concerns and marked as locus of special interest for the monitoring of extremism and counter-terrorism efforts by intelligence agencies worldwide. Drawing on initiatives in the United Kingdom and United States, I re-frame three – covert, overt and covert–overt – intersections of education, security and intelligence studies as a theoretical milieu by which to understand such counter-terrorism efforts. Against the backdrop of new legislative guidance for universities in an era of global terrorism and counter-terrorism efforts by security and intelligence agencies and their Governments, and through a review of Open-Source security/intelligence concerning universities in the United Kingdom and the United States, I show how this interstitial (covert, overt and covert– overt complexity can be further understood by the overarching relationship between securitisation theory and university securitisation. An emergent securitised concept of university life is important because de facto it will potentially effect radical change upon the nature and purposes of the university itself. A current-day situation replete with anxiety and uncertainty, the article frames not only a sharply contested and still unfolding political agenda for universities but a challenge to the very nature and purposes of the university in the face of a potentially existential threat. Terrorism and counterterrorism, as manifest today, may well thus be altering the aims and purposes of the university in ways we as yet do not fully know or understand. This article advances that knowledge and understanding through a theoretical conceptualisation: the counter-terrorist campus.

    The terrorist attacks of 11 September 2001 (hereafter referred to as 9/11) preceded an increase in male fetal deaths and reduced male live births among exposed gestational cohorts across several geographic locations in the United States, including California. We analyze whether the extreme stressor of 9/11 may have selected against frail males in utero by testing if the prevalence of male births with selected defects in California fell among cohorts exposed to the stressor during gestation. We used data from the California Birth Defects Monitoring Program from July 1985 to January 2004 (223 conception cohorts). We included six birth defects that as a group of phenotypes disproportionately affect males. We applied time-series methods and defined as "exposed to 9/11" the cohorts conceived in February, March, April, May, June, July, and August 2001. Three of the seven monthly conception cohorts exposed to 9/11 in utero show lower than expected odds of live born males with the studied defects: February 2001 (odds ratio [OR] = 0.39; 95% confidence interval [CI], 0.21-0.71), May 2001 (OR = 0.36; 95% CI, 0.16-0.81), and August 2001 (OR = 0.51; 95% CI, 0.28-0.93). The population-wide stressor of 9/11 precedes a reduction in the risk of live born males with selected birth defects. Our analysis contributes to the understanding of adaptation to stress among pregnant women exposed to large and unexpected ambient stressors. Results further support the notion that the prevalence of live born defects may reflect temporal variation in cohort selection in utero against frail males.

    The latest terrorist attacks in Europe and in the rest of the world, and the military experience in the most recent conflicts leave us with several lessons learned. The most important is that the fate of the wounded rests in the hands of the one who applies the first dressing, because the victims usually die within the first 10 minutes, before professional care providers or police personnel arrive at the scene. A second lesson is that the primary cause of preventable death in these types of incidents involving explosives and firearms is massive hemorraghe. There is a need to develop a training oriented to citizens so they can identify and use available resources to avoid preventable deaths that occur in this kind of incidents, especially massive hemorrhage. A 7-hour training intervention program was developed and conducted between January and May 2017. Data were collected from participants' answers on a multiple-choice test before and after undertaking the training. Improved mean score for at least 75% of a group's members on the posttraining test was considered reflective of adequate knowledge. A total of 173 participants (n = 74 men [42.8%]; n = 99 women [57.2%]) attended the training. They were classified into three groups: a group of citizens/ first responders with no prior health training, a group of health professionals, and a group of nursing students. Significant differences (ρ < .05) between mean pre- and post-training test scores occurred in each of the three groups. There was a clear improvement in the knowledge of the students after the training when pre- and post-training test scores were compared within the three groups. The greatest improvement was seen in the citizens/first responders group. 2017.

  5. INTERRELATIONS OF JUSTICE, REJECTION, PROVOCATION, AND MORAL DISGUST SENSITIVITY AND THEIR LINKS WITH THE HOSTILE ATTRIBUTION BIAS, TRAIT ANGER AND AGGRESSION

    Full Text Available Several personality dispositions with common features capturing sensitivities to negative social cues have recently been introduced into psychological research. To date, however, little is known about their interrelations, their conjoint effects on behavior, or their interplay with other risk factors. We asked N=349 adults from Germany to rate their justice, rejection, moral disgust, and provocation sensitivity, hostile attribution bias, trait anger, and forms and functions of aggression. The sensitivity measures were mostly positively correlated; particularly those with an egoistic focus, such as victim justice, rejection, and provocation sensitivity, hostile attributions and trait anger as well as those with an altruistic focus, such as observer justice, perpetrator justice, and moral disgust sensitivity. The sensitivity measures had independent and differential effects on forms and functions of aggression when considered simultaneously and when controlling for hostile attributions and anger. They could not be integrated into a single factor of interpersonal sensitivity or reduced to other well-known risk factors for aggression. The sensitivity measures, therefore, require consideration in predicting and preventing aggression.

    Using data from the National Longitudinal Study of Adolescent Health, we provide evidence that young adults respond to crisis-induced depression by exercising less and having breakfast less often. Exogenous variation in the crisis-induced depression is obtained through a unique event in our sample period - the 9/11 terrorist attacks. We compare those who were interviewed just before and just after 9/11 and find a significant and sharp increase in the symptoms of depression. We also provide evidence that this increase is not a September effect, but an effect of the external traumatic event. Copyright © 2012 Elsevier B.V. All rights reserved.

    Objective of the study was to determine pathological changes of the personality of the clean up workers (liquida tors) of the Chornobyl accident and the participants in the anti terrorist operation (ATO) in Eastern Ukraine and radiation threat perception assessment.Design, object and methods. The cross sectional and retrospective assessments of the clean up workers of the Chornobyl accident (n = 185), evacuees from the Chornobyl Exclusion Zone (n = 112) from the randomized sample of individuals who are registered in the Clinical and epidemiological registry (CER) of the State Institution «National Research Center for Radiation Medicine of National Academy of Medical Sciences of Ukraine» [NRCRM] and partici pants of the ATO in Eastern Ukraine (n = 62) who underwent treatment and rehabilitation in the Department of Radiation Psychoneurology of the NRCRM Clinic have been done. The neuropsychiatric clinical and psychometric methods as General Health Questionnaire, GHQ 28; Eysenck Personality Inventory, EPI; method of personality diag nostic by H. Schmischek - K. Leongard, and modified social psychological questionnaire (Joint Study Project 1993) - «dangers questionnaire» were used. Extraversion, hyperthymia and demonstrativity in the clean up workers of the Chornobyl accident and evac uees decreased, while emotiveness, pedantry, anxiety, cyclothymia, excitability and dysthymia increased. Extraversion and hyperthymia decreased in the ATO participants while jams, pedantry, cyclothymia, excitability and dysthymia increased. According to the social psychological assessment («dangers questionnaire») there were found that at present the «national conflict» factor takes among the clean up workers the 22th rank place, evacuees - the 18th, while the participants ATO - the 11th, however the risk perception of disease associated with the presence in the environment of radioactive substances in the ATO participants takes the 6th place, the liquidators - the 8th, the evac

    The "centralization phenomenon" (CP) is the progressive retreat of referred pain towards the spinal midline in response to repeated movement testing (a McKenzie evaluation). A previous study suggested that it may have utility in the clinical diagnosis of discogenic pain and may assist patient selection for discography and specific treatments for disc pain. Estimation of the diagnostic predictive power of centralization and the influence of disability and patient distress on diagnostic performance, using provocation discography as a criterion standard for diagnosis, in chronic low back pain patients. This study was a prospective, blinded, concurrent, reference standard-related validity design carried out in a private radiology clinic specializing in diagnosis of chronic spinal pain. Consecutive patients with persistent low back pain were referred to the study clinic by orthopedists and other medical specialists for interventional radiological diagnostic procedures. Patients were typically disabled and displayed high levels of psychosocial distress. The sample included patients with previous lumbar surgery, and most had unsuccessful conservative therapies previously. results of provocation discography. The CP. Psychometric evaluation: Roland-Morris, Zung, Modified Somatic Perception questionnaires, Distress Risk Assessment Method, and 100-mm visual analog scales for pain intensity. Patients received a single physical therapy examination, followed by lumbar provocation discography. Sensitivity, specificity, and likelihood ratios of the CP were estimated in the group as a whole and in subgroups defined by psychometric measures. A total of 107 patients received the clinical examination and discography at two or more levels and post-discography computed tomography. Thirty-eight could not tolerate a full physical examination and were excluded from the main analysis. Disability and pain intensity ratings were high, and distress was common.

    Lankford criticizes the notion that suicide terrorists are "normal" and argues that they are suicidal. We have two misgivings about this. First, he puts sole focus on the personal side of suicidality and ignores the individual's context. Second, he fails to elaborate on the intent to harm others, which must also include the cultural, political, religious/ideological, and social-organizational factors of suicide terrorism.

    To examine the public’s response to future terrorist attacks, we surveyed 1,001 New Yorkers in the community one year after the September 11 attacks. Overall, New Yorkers were very concerned about future terrorist attacks and also concerned about attacks involving biological or nuclear weapons. In addition, while most New Yorkers reported that if a biological or nuclear attack occurred they would evaluate available information before evacuating, a significant number reported they would immediately evacuate, regardless of police or public health communications to the contrary. The level of public concern was significantly higher on all measures among New York City and Long Island residents (downstate) compared to the rest of the state. A model predicting higher fear of terrorism indicated that downstate residents, women, those 45 to 64 years old, African Americans and Hispanics, those with less education/income, and those more likely to flee, were more fearful of future attacks. In addition, making disaster preparations and carefully evaluating emergency information also predicted a higher level of fear as well. A second model predicting who would flee suggested that those more likely to evaluate available information were less likely to immediately evacuate, while those with a higher fear of future attacks were more likely to flee the area. Given these findings and the possibility of future attacks, mental health professionals need to be more involved in preparedness efforts, especially related to the psychological impact of attacks involving weapons of mass destruction.

  15. Reducing Mortality from Terrorist Releases of Chemical and Biological Agents: I. Filtration for Ventilation Systems in Commercial Building

    1999-09-01

    There is growing concern about potential terrorist attacks involving releases of chemical and/or biological (CB) agents, such as sarin or anthrax, in and around buildings. For an external release, the CB agent can enter the building through the air intakes of a building's mechanical ventilation system and by infiltration through the building envelope. For an interior release in a single room, the mechanical ventilation system, which often recirculates some fraction of the air within a building, may distribute the released CB agent throughout the building. For both cases, installing building systems that remove chemical and biological agents may be the most effective way to protect building occupants. Filtration systems installed in the heating, ventilating and air-conditioning (HVAC) systems of buildings can significantly reduce exposures of building occupants in the event of a release, whether the release is outdoors or indoors. Reduced exposures can reduce the number of deaths from a terrorist attack. The purpose of this report is to provide information and examples of the design of filtration systems to help building engineers retrofit HVAC systems. The report also provides background information on the physical nature of CB agents and brief overviews of the basic principles of particle and vapor filtration.

    Acts of terrorism have an extremely negative impact on the mental health of children and families. The school siege in Beslan, Russia, in 2004, represents a particularly traumatizing event as it was directed specifically at children and involved the entire community. This qualitative study aims to: (a) examine caregiver reactions to the terrorist attack in Beslan as reported 3 months after the traumatic event; (b) determine the extent to which indigenous cultural values and religious belief systems play a role in Beslan's caregivers' reactions to such event; and (c) identify variables that may function as sources of resilience to caregivers. A convenience sample of 17 primary caregivers from Beslan with at least one child who survived the school siege were asked to participate in semi-structured interviews. Narratives generated from the interviews were qualitatively analyzed using a thematic approach; nine major themes were identified. Caregivers' concerns centered on children's physical and psychological well-being, the reorganization of family life, and the disruption of community ties. Cultural values of pride, heroism, courage, and revenge emerged as relevant aspects shaping caregivers' reactions to the traumatic event. Possible sources of resilience included the willingness to return to normality, social support, and the reaffirmation of positive, culturally shared values in face of the perceived threat of future terrorist attacks. Findings are discussed in terms of their theoretical implications on the effects of trauma on children and families as well as interventions with highly traumatized populations in diverse cultural settings.

    U.S. airports and airliners are prime terrorist targets. Not only do the facilities and equipment represent high-value assets, but the fear and dread that is spread by such attacks can have tremendous effects on the U.S. economy. This article presents the methodology, data, and estimates of the macroeconomic impacts stemming from behavioral responses to a simulated terrorist attack on a U.S. airport and on a domestic airliner. The analysis is based on risk-perception surveys of these two scenarios. The responses relate to reduced demand for airline travel, shifts to other modes, spending on nontravel items, and savings of potential travel expenditures by U.S. resident passengers considering flying domestic routes. We translate these responses to individual spending categories and feed these direct impact results into a computable general equilibrium (CGE) model of the U.S. economy to ascertain the indirect and total impacts on both the airline industry and the economy as a whole. Overall, the estimated impacts on GDP of both types of attacks exceed $10B. We find that the behavioral economic impacts are almost an order of magnitude higher than the ordinary business interruption impacts for the airliner attack and nearly two orders of magnitude higher for the airport attack. The results are robust to sensitivity tests on the travel behavior of U.S. residents in response to terrorism. © 2016 Society for Risk Analysis.

    Dealing with children who have disruptive behavior disorders can evoke feelings of frustration and anger in their therapists. D.W. Winnicott discussed the complexities in the treatment of enraging patients in his article "Hate in the Countertransference" (1949). In the following paper, I will depict the relationship between limit setting, projective identification dynamics, and enraging behavior in the treatment of a provocative latency-aged boy. I will argue that poor limit setting caused by powerful projective identification dynamics were central to the pathology of the boy and his family. These dynamics partially repeated in the boy's treatment--an outcome of which Winnicott had warned. The repetition contributed to the boy becoming physically out of control in my office and led to a disruption in his treatment. The establishment of solid limits by addressing projective identification forces was necessary for the improvement in the disruptive behavior of the child.

  20. Late airway obstruction and neutrophil infiltration in sensitized mice after antigen provocation were suppressed by selective and non-selective phosphodiesterase inhibitors

    Full Text Available Suppression of antigen-induced late airway obstruction associated with neutrophilic inflammation by selective and non-selective phosphodiesterase (PDE inhibitors was investigated in mice. Respiratory resistance (Rrs increased in sensitized BDF1 mice 4-6 h after antigen provocation, whereas no obvious immediate reaction was observed. This reaction was associated with marked airway neutrophilia without significant infiltration of eosinophils. A selective PDE IV inhibitor, T-440 (10-30 mg/kg, and a non-selective PDE inhibitor, theophylline (10 mg/kg, significantly inhibited airway obstruction and neutrophilia when administered orally. An anti-allergic drug, ketotifen (1 mg/kg, caused slight inhibition of airway obstruction, whereas it did not affect airway neutrophilia. These results suggest that neutrophilic inflammation plays a role in the airway obstructive reaction and that PDE has a regulatory role in obstructive airway disease associated with airway inflammation.

    Self-reported penicillin allergy is common among patients attending the ED, but is a poor predictor of true immunoglobulin E-mediated hypersensitivity to penicillin. We hypothesise that with a combination of skin testing and drug provocation testing, selected patients can be safely de-labelled of their allergy. This prospective study enrolled a sample of patients presenting to an urban academic ED between 2011 and 2016 with a self-reported allergy to penicillin. Standardised skin prick and intradermal testing with amoxicillin and both major and minor determinants of penicillin was performed in the department. If negative, testing was followed by a graded oral challenge of amoxicillin over 9 days. The primary end point was the allergy status of participants at the end of the study. A total of 100 patients (mean age 42; standard deviation 14 years; 54% women) completed the testing. Of these, 81% (95% confidence interval 71.9-88.2) showed no hypersensitivity to penicillin and were labelled non-allergic. The majority (16/19) of allergies were confirmed by skin testing, with three suspected allergies detected by the oral challenge. Women were more likely than men to have a true penicillin allergy, with odds ratio of 4.0 (95% confidence interval 1.23-13.2). There were no serious adverse events. Selected patients in the ED who self-report an allergy to penicillin can be safely tested there for penicillin allergy, using skin tests and oral drug provocation testing. This testing allows a significant de-labelling of penicillin allergy, with the majority of these patients able to tolerate penicillin without incident. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Whether additional intracoronary acetylcholine (ACH) injections are required for severe coronary spasm without limited coronary flow in the ACH provocation test remains unclear. We used (123)I-β-methyl-iodophenyl pentadecanoic acid ((123)I-BMIPP) to identify myocardial ischemic memory to compare the severity of myocardial fatty acid dysmetabolism among Thrombolysis in Myocardial Infarction (TIMI) grade flow.Thirteen hypertensive volunteers (mean age, 69.5 years) and 37 patients with VSA (mean age, 62.8 years) were enrolled. The patients with VSA were stratified according to TIMI flow grades of 3 (90% luminal narrowing; n = 12) or TIMI 0-2 (≥ 99% or total occlusion; n = 25) during ACH provocation tests. Two weeks after cardiac catheterization, (123)I-BMIPP myocardial scintigraphic images were obtained at 15 minutes (early) and at 4 hours (delayed) after tracer injection. The heart-to-mediastinum (H/M) ratio and washout rates (WR) were calculated from planar images.The TIMI 3 and TIMI 0-2 groups had significantly lower early and delayed H/M ratios than controls but the difference did not reach significance between the two groups (Early: 2.7 ± 0.5 versus 2.3 ± 0.4 and 2.2 ± 0.3, P = 0.024; Delayed: 2.4 ± 0.4 versus 1.8 ± 0.3 and 1.8 ± 0.3, P = 0.001). The washout rate was greater for TIMI 0-2 than the controls.The severity of myocardial fatty acid dysmetabolism did not differ between TIMI 3 and TIMI 0-2 coronary spasms. Additional ACH might not be required considering safety and the severity of coronary spams with TIMI 3 grade flow.

    Schwartz, Dagan; Pinkert, Moshe; Leiba, Adi; Oren, Meir; Haspel, Jacob; Levi, Yehezkel; Goldberg, Avishay; Bar-Dayan, Yaron

    2007-01-01

    Mass-casualty incidents (MCIs) can occur outside of major metropolitan areas. In such circumstances, the nearest hospital seldom is a Level-1 Trauma Center. Moreover, emergency medical services (EMS) capabilities in such areas tend to be limited, which may compromise prehospital care and evacuation speed. The objective of this study was to extract lessons learned from the medical response to a terrorist event that occurred in the marketplace of a small Israeli town on 26 October 2005. The lessons pertain to the management of primary and secondary evacuation and the operational practices by the only hospital in the town, which is designated as a Level-2 Trauma Center. Data were collected during the event by Home Front Command Medical Department personnel. After the event, formal and informal debriefings were conducted with EMS personnel, the hospitals involved, and the Ministry of Health. The medical response components, interactions (mainly primary triage and secondary distribution), and the principal outcomes were analyzed. The event is described according to Disastrous Incidents Systematic Analysis Through Components, Interactions, Results (DISAST-CIR) methodology. The suicide bomber and four victims died at the scene, and two severely injured patients later died in the hospital. A total of 58 wounded persons were evacuated, including eight severely injured, two moderately injured, and 48 mildly injured. Forty-nine of the wounded arrived to the nearby Hillel Yafe Hospital, including all eight of the severely injured victims, the two moderately injured, and 39 of the mildly injured. Most of the mildly injured victims were evacuated in private cars by bystanders. Five other area hospitals were alerted, three of which primarily received the mildly injured victims. Two distant, Level-1 Trauma Centers also were alerted; each received one severely injured patient from Hillel Yafe Hospital during the secondary distribution process.

    2015-01-01

    September 11, 2001 saw the dawn of the US-led global war on terror, a combined diplomatic, military, social, and cultural war on terrorist activities. Chemical, biological, radiological, nuclear, and high-yield explosives (CBRNE), as a group of tactics, are often the preferred weapons of terrorists across the globe. We undertook a survey of US medical schools to determine what their self-reported level of training for terrorist events encompasses during the four years of undergraduate medical education. We surveyed 170 medical schools in the US and Puerto Rico using a five-question, internet-based survey, followed by telephone calls to curriculum offices for initial nonresponders. We used simple descriptive statistics to analyze the data. A majority of US medical schools that completed the survey (79 schools or 65.3%) have no required lecture or course on CBRNE or terrorist activities during the first or second year (preclinical years). Ninety-eight out of the 121 respondents (81.0%), however, believed that CBRNE training was either very important or somewhat important, as reflected in survey answers. Most physician educators believe that training in CBRNE is important; however this belief has not resulted in widespread acceptance of a CBRNE curriculum in US medical schools.

  15. Explaining religiosity: towards a unified theoretical model.

    Science.gov (United States)

    Stolz, Jörg

    2009-06-01

    The article presents a unified theoretical model, explaining differences in Christian and 'alternative' religiosity at individual and collective levels. The model reconstructs and integrates the most important theories explaining religiosity (deprivation, regulation, socialization, cultural production, and ethnicity) as complementary causal mechanisms in a rational-action based framework. It is maintained that the mechanisms of the various theories are not exclusive, but complementary, and that integration into the general model is both theoretically and empirically beneficial. The model is tested on representative data from Switzerland. Substantively, I find for the Swiss case that Christian religiosity can be best explained by a religious socialization mechanism. The most important mechanisms accounting for alternative religiosity involve deprivation, gender, and age.

  16. Prevalence and Correlates of Sleep Problems in Adult Israeli Jews Exposed to Actual or Threatened Terrorist or Rocket Attacks

    Palmieri, Patrick A.; Chipman, Katie J.; Canetti, Daphna; Johnson, Robert J.; Hobfoll, Stevan E.

    2010-01-01

    Study Objectives: To estimate the prevalence of, and to identify correlates of clinically significant sleep problems in adult Israeli citizens exposed to chronic terrorism and war trauma or threat thereof. Methods: A population-based, cross-sectional study of 1001 adult Israeli citizens interviewed by phone between July 15 and August 26, 2008. The phone survey was conducted in Hebrew and assessed demographics, trauma/stressor exposure, probable posttraumatic stress disorder (PTSD), probable depression, and sleep problems. Probable PTSD and depression were assessed with the PTSD Symptom Scale (PSS) and Patient Health Questionnaire (PHQ-9), respectively, following DSM-IV diagnostic criteria. Sleep problems in the past month were assessed with the Pittsburgh Sleep Quality Index (PSQI), on which a global composite score ≥ 6 indicates a clinical-level sleep problem. Results: Prevalence of probable PTSD and depression was 5.5% and 5.8%, respectively. Prevalence of clinically significant sleep problems was 37.4% overall, but was significantly higher for probable PTSD (81.8%) and probable depression (79.3%) subgroups. Independent correlates of poor sleep included being female, older, less educated, experiencing major life stressors, and experiencing psychosocial resource loss. Psychosocial resource loss due to terrorist attacks emerged as the strongest potentially modifiable risk factor for sleep problems. Conclusions: Sleep problems are common among Israeli adults living under chronic traumatic threat and trauma exposure. Given the continuing threat of war, interventions that bolster psychosocial resources may play an important role in preventing or alleviating sleep problems in this population.

  17. Responding to Terrorist Incidents in Your Community: Flammable-Liquid Fire Fighting Techniques for Municipal and Rural Firefighters

    Energy Technology Data Exchange (ETDEWEB)

    Denise Baclawski

    2010-03-08

    The University of Nevada, Reno Fire Science Academy (FSA) applied for grant funding to develop and deliver programs for municipal, rural, and volunteer firefighters. The FSA specializes in preparing responders for a variety of emergency events, including flammable liquid fires resulting from accidents, intentional acts, or natural disasters. Live fire training on full scale burnable props is the hallmark of FSA training, allowing responders to practice critical skills in a realistic, yet safe environment. Unfortunately, flammable liquid live fire training is often not accessible to municipal, rural, or volunteer firefighters due to limited department training budgets, even though most department personnel will be exposed to flammable liquid fire incidents during the course of their careers. In response to this training need, the FSA developed a course during the first year of the grant (Year One), Responding to Terrorist Incidents in Your Community: Flammable-Liquid Fire Fighting Techniques for Municipal and Rural Firefighters. During the three years of the grant, a total of 2,029 emergency responders received this training. In Year Three, two new courses, a train-the-trainer for Responding to Terrorist Incidents in Your Community and Management of Large-Scale Disasters for Public Officials were developed and pilot tested during the Real-World Disaster Management Conference held at the FSA in June of 2007. Two research projects were conducted during Years Two and Three. The first, conducted over a two year period, evaluated student surveys regarding the value of the flammable liquids training received. The second was a needs assessment conducted for rural Nevada. Both projects provided important feedback and a basis for curricula development and improvements.

  12. Children's Theories and the Drive to Explain

    Science.gov (United States)

    Schwitzgebel, Eric

    Debate has been growing in developmental psychology over how much the cognitive development of children is like theory change in science. Useful debate on this topic requires a clear understanding of what it would be for a child to have a theory. I argue that existing accounts of theories within philosophy of science and developmental psychology either are less precise than is ideal for the task or cannot capture everyday theorizing of the sort that children, if they theorize, must do. I then propose an account of theories that ties theories and explanation very closely together, treating theories primarily as products of a drive to explain. I clarify some of the positions people have taken regarding the theory theory of development, and I conclude by proposing that psychologists interested in the ''theory theory'' look for patterns of affect and arousal in development that would accompany the existence of a drive to explain.

    Educators and economists concerned with monetary reform face the extraordinary challenge of explaining to the public and its elected representatives not only what a reformed system would look like, but also how the current system works. Centrally, the point that in a modern economy money is largely...... created by commercial banks, as explained by the Bank of England recently (McLeay, Radia & Thomas, 2014b), is often met with incredulity: “What do you mean, created?” This paper introduces five easy-to-grasp analogies that educators and reformers may use to convey key money-creation concepts to a lay...... audience. The analogies offered include (1) money as patches in an expandable patchwork quilt that covers a nation’s real assets, (2) the money supply as water in a bathtub with a faucet and a drain, (3) money understood as debt in a model economy run by schoolchildren, (4) the misleading concept of a bank...

  14. Drug detoxification dynamics explain the postantibiotic effect.

    Science.gov (United States)

    Srimani, Jaydeep K; Huang, Shuqiang; Lopatkin, Allison J; You, Lingchong

    2017-10-23

    The postantibiotic effect (PAE) refers to the temporary suppression of bacterial growth following transient antibiotic treatment. This effect has been observed for decades for a wide variety of antibiotics and microbial species. However, despite empirical observations, a mechanistic understanding of this phenomenon is lacking. Using a combination of modeling and quantitative experiments, we show that the PAE can be explained by the temporal dynamics of drug detoxification in individual cells after an antibiotic is removed from the extracellular environment. These dynamics are dictated by both the export of the antibiotic and the intracellular titration of the antibiotic by its target. This mechanism is generally applicable for antibiotics with different modes of action. We further show that efflux inhibition is effective against certain antibiotic motifs, which may help explain mixed cotreatment success. © 2017 The Authors.

  15. John Watson's paradoxical struggle to explain Freud.

    Science.gov (United States)

    Rilling, M

    2000-03-01

    John Watson was fascinated by the discoveries of psychoanalysis, but he rejected Freud's central concept of the unconscious as incompatible with behaviorism. After failing to explain psychoanalysis in terms of William James's concept of habit, Watson borrowed concepts from classical conditioning to explain Freud's discoveries. Watson's famous experiment with Little Albert is interpreted not only in the context of Pavlovian conditioning but also as a psychoanalytically inspired attempt to capture simplified analogues of adult phobic behavior, including the "transference" of emotion in an infant. Watson used his behavioristic concept of conditioned emotional responses to compete with Freud's concepts of displacement and the unconscious transference of emotion. Behind a mask of anti-Freudian bias, Watson surprisingly emerges as a psychologist who popularized Freud and pioneered the scientific appraisal of his ideas in the laboratory.

    Cheryan, Sapna; Plaut, Victoria C

    2010-10-01

    What processes best explain women's underrepresentation in science, math, and engineering fields in the U.S.? Do they also explain men's underrepresentation in the humanities? Two survey studies across two U.S. West Coast universities (N = 62; N = 614) addressed these questions in the context of two fields: one male-dominated (computer science) and the other female-dominated (English). Among a set of social predictors-including perceived similarity to the people in the field, social identity threats, and expectations of success-the best mediator of women's lower interest in computer science and men's lower interest in English was perceived similarity. Thus, changing students' social perceptions of how they relate to those in the field may help to diversify academic fields.

    In this paper, the author formulates a theory to explain why human sexual orientation seems to run amok. The 'psychic instrument', as he terms it, is the baby's dreaming mind which interprets or misinterprets input from its sociocultural sexual environment. The baby, already born an omnisexual being, then develops a fantasy life with socially sanctioned or unsanctioned fetishes which are likely to be expressed when certain triggering situations arise.

    Intramuscular injections can provoke muscular paralysis especially, if the child has had exposure to polio virus. The purpose of the study was to determine the association with known risk factors for motor disabilities in two remote villages of North Karnataka (India), where an increased number of disabled people among select communities had been reported. A community based survey was conducted. The selection of study subjects was done through screening, history related with occurrence of musculoskeletal disability, screening and general examination of the affected joints and muscles. Data analysis was done by estimation of percentages. Among the physical disabilities identified, the most common was post-polio residual paralysis. 35.65% (n = 41) subjects had developed paralysis following the administration of an intramuscular injection when they had acute viremia in childhood, indicating that (probably) muscle paralysis would have been provoked by intramuscular injections, resulting in provocative poliomyelitis. Unnecessary injection must be avoided in children during acute viremia state and use of oral polio vaccine should be encouraged.

A minimum time limit for follow-up was 6mo.RESULTS:Thirty-three patients (thirty-eight eyes were followed for 17.7±8.37mo (range 7-41mo after LPIP. Positive results of DRPT decreased from 38 eyes to 9 eyes (23.7% after LPIP. Peripheral anterior synechiae of angle in 34 of 38 eyes (89.5% remained unchanged at dynamic gonioscopy throughout the follow-up period after LPIP.CONCLUSION:LPIP decreased positive rates of the DRPT significantly. The mechanism may be that LPIP minimized contact between the peripheral iris and trabecular meshwork, which is a key factor for developing peripheral anterior synechiae.

    Model based analysis of calibrated diffuse reflectance spectroscopy can be used for determining oxygenation and concentration of skin chromophores. This study aimed at assessing the effect of including melanin in addition to hemoglobin (Hb) as chromophores and compensating for inhomogeneously distributed blood (vessel packaging), in a single-layer skin model. Spectra from four humans were collected during different provocations using a twochannel fiber optic probe with source-detector separations 0.4 and 1.2 mm. Absolute calibrated spectra using data from either a single distance or both distances were analyzed using inverse Monte Carlo for light transport and Levenberg-Marquardt for non-linear fitting. The model fitting was excellent using a single distance. However, the estimated model failed to explain spectra from the other distance. The two-distance model did not fit the data well at either distance. Model fitting was significantly improved including melanin and vessel packaging. The most prominent effect when fitting data from the larger separation compared to the smaller separation was a different light scattering decay with wavelength, while the tissue fraction of Hb and saturation were similar. For modeling spectra at both distances, we propose using either a multi-layer skin model or a more advanced model for the scattering phase function.

    This paper presents the first experience gained in Russia in expert identification practice with complex utilization of technologies of molecular genetic individualization of biological objects for solving identification tasks requiring the maximum complete armory of mutually supplementing means. This is particularly important for forensic expert personality identification in cases with many deaths, when indirect identification has to be resorted to, consisting in the use of biological samples from relatives of the victims as the identifying objects. Methodological approaches and concepts of expert studies, used for identification of the remains of people who died in terroristic acts committed in Moscow in September, 1999, are discussed. The results of this study and methodological experience notably extend the potentialities of expert evaluation as regards forensic medical identification of victims of overall disasters, terroristic acts, and war conflicts.

  7. Dissipative dark matter explains rotation curves

    Dissipative dark matter, where dark matter particles interact with a massless (or very light) boson, is studied. Such dark matter can arise in simple hidden sector gauge models, including those featuring an unbroken U (1 )' gauge symmetry, leading to a dark photon. Previous work has shown that such models can not only explain the large scale structure and cosmic microwave background, but potentially also dark matter phenomena on small scales, such as the inferred cored structure of dark matter halos. In this picture, dark matter halos of disk galaxies not only cool via dissipative interactions but are also heated via ordinary supernovae (facilitated by an assumed photon-dark photon kinetic mixing interaction). This interaction between the dark matter halo and ordinary baryons, a very special feature of these types of models, plays a critical role in governing the physical properties of the dark matter halo. Here, we further study the implications of this type of dissipative dark matter for disk galaxies. Building on earlier work, we develop a simple formalism which aims to describe the effects of dissipative dark matter in a fairly model independent way. This formalism is then applied to generic disk galaxies. We also consider specific examples, including NGC 1560 and a sample of dwarf galaxies from the LITTLE THINGS survey. We find that dissipative dark matter, as developed here, does a fairly good job accounting for the rotation curves of the galaxies considered. Not only does dissipative dark matter explain the linear rise of the rotational velocity of dwarf galaxies at small radii, but it can also explain the observed wiggles in rotation curves which are known to be correlated with corresponding features in the disk gas distribution.

    The terrorist attacks (fusillades and suicide attacks) in Paris on 13 November 2015 have had a major psychic impact on all individuals directly or secondarily exposed to them. Medico-psychological unit (CUMP) of the Paris Île-de-France region's immediate care services were immediately mobilized and rapidly strengthened by all regional medico-psychological units (CUMP) throughout the country. Psychological assistance has been provided in several key points of Paris and specifically in the 11th district City Hall of Paris where Lyon's Medico-psychological unit was located. These specific immediate psychological assistances, referred to as a "defusing process" by the medico-psychological unit (CUMP), are mostly devoted to provide the victims with an entry point to a psychological healthcare relationship and give them a first sense of soothing and relief even though they do not prevent further psychological care follow up for the victims. Nonetheless, the potential therapeutic effect of this "defusing process" has not yet been sufficiently established nor demonstrated by any scientific study. A phoning survey was carried out one-month post-terrorist attacks and interviewed the 129 victims who benefited from the "defusing process" conducted by Lyon's medico-psychological unit (CUMP) in order to collect data and assess its effects. These people, whether directly exposed, bereaved relatives or witnesses, whose average age is 35, are mostly living in the Île-de-France region. Most of them present a high score on the IES-R scale, whether they were directly exposed, bereaved relatives or witnesses. Almost all of them (96.5%) experienced at least one medical care contact within this one-month post-trauma period with psychotropic medication for 37% of them. Regarding the defusing conducted by Lyon's medico-psychological unit (CUMP) in the 11th district City Hall of Paris, it appears that 93% of the victims who were looked after indicated that they were satisfied and 87.4% of

    2014-02-24

    Nanoscale electrostatic microtubule disassembly forces between positively charged molecules in kinetochores and negative charges on plus ends of microtubules have been implicated in poleward chromosome motions and may also contribute to antipoleward chromosome movements. We propose that chromosome congression can be understood in terms of antipoleward nanoscale electrostatic microtubule assembly forces between negatively charged microtubule plus ends and like-charged chromosome arms, acting in conjunction with poleward microtubule disassembly forces. Several other aspects of post-attachment prometaphase chromosome motions, as well as metaphase oscillations, are consistently explained within this framework.

    This article explores the determinants of the perceptions of the unemployed in 29 European countries along three dimensions: whether people see the unemployed as the ‘government’s responsibility’; whether they believe the unemployed do not ‘try hard to find a job’; and whether they think that the standard of living of the unemployed is ‘bad’. I derive a number of expectations from the political economy literature on policy preferences and test whether these expectations explain variation in t...

  17. Developmental systems theory: what does it explain, and how does it explain it?

    Griffiths, Paul E; Tabery, James

    2013-01-01

    We examine developmental systems theory (DST) with two questions in mind: What does DST explain? How does DST explain it? To answer these questions, we start by reviewing major contributions to the origins of DST: the introduction of the idea of a "developmental system", the idea of probabilistic epigenesis, the attention to the role of information in the developmental system, and finally the explicit identification of a DST. We then consider what DST is not, contrasting it with two approaches that have been foils for DST: behavioral genetics and nativist cognitive psychology. Third, we distill out two core concepts that have defined DSTthroughout its history: epigenesis and developmental dynamics. Finally, we turn to how DST explains, arguing that it explains by elucidating mechanisms.

  18. Boosted Regression Tree Models to Explain Watershed ...

    Science.gov (United States)

    Boosted regression tree (BRT) models were developed to quantify the nonlinear relationships between landscape variables and nutrient concentrations in a mesoscale mixed land cover watershed during base-flow conditions. Factors that affect instream biological components, based on the Index of Biotic Integrity (IBI), were also analyzed. Seasonal BRT models at two spatial scales (watershed and riparian buffered area [RBA]) for nitrite-nitrate (NO2-NO3), total Kjeldahl nitrogen, and total phosphorus (TP) and annual models for the IBI score were developed. Two primary factors — location within the watershed (i.e., geographic position, stream order, and distance to a downstream confluence) and percentage of urban land cover (both scales) — emerged as important predictor variables. Latitude and longitude interacted with other factors to explain the variability in summer NO2-NO3 concentrations and IBI scores. BRT results also suggested that location might be associated with indicators of sources (e.g., land cover), runoff potential (e.g., soil and topographic factors), and processes not easily represented by spatial data indicators. Runoff indicators (e.g., Hydrological Soil Group D and Topographic Wetness Indices) explained a substantial portion of the variability in nutrient concentrations as did point sources for TP in the summer months. The results from our BRT approach can help prioritize areas for nutrient management in mixed-use and heavily impacted watershed

    Recent studies have suggested that incarceration dramatically increases the odds of divorce, but we know little about the mechanisms that explain the association. This study uses prospective longitudinal data from a subset of married young adults in the National Longitudinal Study of Adolescent Health (N = 1,919) to examine whether incarceration is associated with divorce indirectly via low marital love, economic strain, relationship violence, and extramarital sex. The findings confirmed that incarcerations occurring during, but not before, a marriage were associated with an increased hazard of divorce. Incarcerations occurring during marriage also were associated with less marital love, more relationship violence, more economic strain, and greater odds of extramarital sex. Above-average levels of economic strain were visible among respondents observed preincarceration, but only respondents observed postincarceration showed less marital love, more relationship violence, and higher odds of extramarital sex than did respondents who were not incarcerated during marriage. These relationship problems explained approximately 40 percent of the association between incarceration and marital dissolution. These findings are consistent with theoretical predictions that a spouse’s incarceration alters the rewards and costs of the marriage and the relative attractiveness of alternative partners.

  20. Terrorist Threat Construction and the Transition to Permanent British Counterterrorism Law

    2011-11-01

    Full Text Available 'After over two decades of renewing temporary counterterrorism laws in Britain from the early 1970s, making such measures permanent with the Terrorism Act 2000 was not necessarily a predictable or predetermined outcome. The Northern Ireland peace process was underway, the Labour party who had voted against temporary counterterrorism laws for over a decade was newly back in power, and historical context pointed to an inconclusiveness around how effective such laws actually were in reducing insecurity. In this article I argue a key element helping explain this transition from temporary to permanent counterterrorism law lies in how particular threat and referent identities were constructed in official British discourse. Drawing on empirical research from a relational-securitization analysis of official British discourses from the late 1960s to the present, this paper argues that processes of identity construction were essential to introducing and justifying the Terrorism Act 2000. The deployment of particular threat and referent labels established in discourse before events such as 9/11 or 7/7, such as “international” terrorism, helped enable the shift from counterterrorism law from temporary emergency response to permanent policy practice.'
