    1997-01-01

    A single start multiple stop time digitizer has been developed which can digitize the time between a start pulse and multiple stop pulses. The system has been designed as a PC add on card. The resolution of the instrument is 10 nSecs and the maximum length of time that it can measure is 1.28 milliseconds. Apart from time digitization, it can also resolve the height of the incoming pulses into 64 levels. After each input pulse the system dead time is less than 300 nSecs. The driver software for this card has been developed on DOS platform. It uses graphical user interface to provide a user friendly environment. The system is intended to be used in time of flight mass spectroscopy experiments. It can also be used for time of flight experiments in nuclear physics. (author). 2 figs

  2. Mr. Trump: How I learned to stop worrying and love the patient-aggressor.

    This paper offers an integration of social issues, psychoanalytic theory, and analytic experience in the treatment of a patient whose political values and identifications differed significantly from my own. Our political leanings facilitated a dynamic tension of difference, power, and aggression that mirrored how each of us felt in relation to the current social-political milieu. In particular, the sadomasochistic dynamics on display in the treatment offered me a unique way of understanding my relationship with my patient and opened new ways of understanding the political present. In the end, I learned to stop worrying about getting rid of anger, aggression, and splitting, and instead to embrace what these feelings and behaviors can tell me as a therapist, and what they can inform for my patients about the nature of relationality, identity, and difference. © 2018 Wiley Periodicals, Inc.

    Full Text Available The aim of our study was to explore reasons for starting and then stopping electronic cigarette (e-cigarette use. Among a national sample of 3878 U.S. adults who reported ever trying e-cigarettes, the most common reasons for trying were curiosity (53%; because a friend or family member used, gave, or offered e-cigarettes (34%; and quitting or reducing smoking (30%. Nearly two-thirds (65% of people who started using e-cigarettes later stopped using them. Discontinuation was more common among those whose main reason for trying was not goal-oriented (e.g., curiosity than goal-oriented (e.g., quitting smoking (81% vs. 45%, p < 0.001. The most common reasons for stopping e-cigarette use were that respondents were just experimenting (49%, using e-cigarettes did not feel like smoking cigarettes (15%, and users did not like the taste (14%. Our results suggest there are two categories of e-cigarette users: those who try for goal-oriented reasons and typically continue using and those who try for non-goal-oriented reasons and then typically stop using. Research should distinguish e-cigarette experimenters from motivated users whose decisions to discontinue relate to the utility or experience of use. Depending on whether e-cigarettes prove to be effective smoking cessation tools or whether they deter cessation, public health programs may need distinct strategies to reach and influence different types of users.

    Full Text Available Internet teaching is a worthy topic today because changes in society demand "that learners change their knowledge and skill bases and change them faster than at any time in history" [1], and Internet teaching is proving to be one of the best ways to reach those learners. This paper explores ten of the most common difficulties of online courses. It explains how the proper use of readily available technology can be brought to bear on these difficulties in ways that will reduce worry and stress both for beginners faced with teaching a first course and for professors who already have taught online courses but may be seeking ways to improve upon the experience.

    Excessive and uncontrollable worry is a defining feature of Generalized Anxiety Disorder (GAD). An important endeavor in the treatment of pathological worry is to understand why some people are unable to stop worrying once they have started. Worry perseveration is associated with a tendency to deploy goal-directed worry rules (known as “as many as can” worry rules; AMA). These require attention to the goal of the worry task and continuation of worry until the aims of the “worry bout” are achi...

    Many drivers of personal and commercial vehicles believe that turning the vehicle off and on frequently instead of idling will cause premature wear of the starter system (starter motor and starter battery). As a result, they are concerned that the replacement cost of the starter motor and/or battery due to increased manual engine cycling would be more than the cumulative cost of the fuel saved by not idling unnecessarily. A number of variables play a role in addressing this complex concern, including the number of starting cycles per day, the time between starting cycles, the intended design life of the starting system, the amount of fuel used to restart an engine, and the cumulative cost of the saved fuel. Qualitative and quantitative information from a variety of sources was used to develop a life-cycle economic model to evaluate the cost and quantify the realistic factors that are related to the permissible frequency of starter motor cycles for the average vehicle to economically minimize engine idle time. Annual cost savings can be calculated depending on shutdown duration and the number of shutdown cycles per day. Analysis shows that cost savings are realized by eliminating idling exceeding one minute by shutting down the engine and restarting it. For a typical motorist, the damage to starting system components resulting from additional daily start cycles will be negligible. Overall, it was found that starter life is mostly dependent on the total number of start cycles, while battery life is more dependent on ensuring a full charge between start events.

  10. Revised emission factors for gas engines including start/stop emissions

    2008-06-15

    Liberalisation of the electricity market has led to Danish gas engine plants increasingly converting to the spot and regulating power markets. In order to offer regulating power, plants need to be able to start and stop the engines at the plants quickly. The liberalisation causes a considerable change of operation practice of the engines e.g. less full load operation hours /year. The project provides an inventory determining the scale of the emissions during the start and stop sequence as well as proposals for engine modifications aimed at reducing start/stop emissions. This report includes calculation of emission factors as well as an inventory of total emissions and reduction potentials. (au)

    Today, the use of engine start-stop technology - a system designed to cut fuel consumption when the vehicle stops or, in future applications, when vehicles are in coasting or ''sailing'' mode - is gaining ground in more and more vehicle classes. Shutting off the internal combustion engine, though, detrimentally affects cabin air conditioning because the belt-driven A/C compressor is likewise deactivated, thus bringing the vapor compression process to a standstill. As a result, during extended stop periods and in warm weather vent temperatures and air humidity rapidly increase.

  12. "I can't stop worrying about everything"—experiences of rural Bangladeshi women during the first postpartum months.

    Over recent years, researchers have found evidence which indicates that the prevalence of postpartum depressive symptoms crosses cultural boundaries and is reported to be at least as high in non-Western countries as in Western countries. However, qualitative studies about new mothers' experiences from non-Western countries, such as Bangladesh, are rare, particularly in rural areas. This study aims to describe the experiences and concerns of rural Bangladeshi mothers with postpartum depressive symptoms. Open narrative interviews were conducted with 21 mothers with depressive symptoms 2-3 months postpartum, consecutively selected from a longitudinal study about prevalence and risk factors of perinatal depressive symptoms. Inductive content analysis was used to analyse data and three themes emerged: family dynamics, living at the limits of survival, and role of the cultural context after childbirth. These themes were based on six categories and 15 subcategories. The findings show that troublesome family relationships, including intimate partner violence and violence in the family, influenced the mothers' mental well-being. They and their families lived at the limit of survival and the mothers expressed fear and worries about their insecure situation regarding economic difficulties and health problems. They felt sorry for being unable to give their infants a good start in life and sad because they could not always follow the traditional norms related to childbirth. Thus, it is important to focus on the depressive symptoms among new mothers and offer counselling to those showing depressive symptoms, as the cultural traditions do not always alleviate these symptoms in the changing Bangladeshi society today.

    Global automakers are accelerating the development of fuel efficient vehicles, as a part of meeting regional regulatory CO2 emissions requirements. The micro hybrid vehicles with auto start-stop functionality are considered economical solutions for the stringent European regulations. Flooded lead acid batteries were initially considered the most economical solution for idle-stop systems. However, the dynamic charge acceptance (DCA) at lower state-of-charge (SOC) was limiting the life of the batteries. While improved lead-acid batteries with AGM and VRLA features have improved battery longevity, they do not last the life of the vehicle. The United States Advanced Battery Consortium (or USABC, a consortium of GM, Ford, and Chrysler) analyzed energy storage needs for a micro hybrid automobile with start-stop capability, and with a single power source. USABC has analyzed the start-stop behaviors of many drivers and has developed the requirements for the start-stop batteries (Table 3). The testing procedures to validate the performance and longevity were standardized and published. The guideline for the cost estimates calculations have also been provided, in order to determine the value of the newly developed modules. The analysis effort resulted in a set of requirements which will help the battery manufacturers to develop a module to meet the automotive Original Equipment Manufacturers (OEM) micro hybrid vehicle requirements. Battery developers were invited to submit development proposals and two proposals were selected for 50% cost share with USABC/DOE.

    The National Aeronautics and Space Administration s (NASA s) history is built on a foundation of can-do strength, while pointing to the Saturn/Apollo Moon missions in the 1960s and 1970s as its apex a sentiment that often overshadows the potential that lies ahead. The chronicle of America s civil space agenda is scattered with programs that got off to good starts with adequate resources and vocal political support but that never made it past a certain milestone review, General Accountability Office report, or Congressional budget appropriation. Over the decades since the fielding of the Space Shuttle in the early 1980s, a start-stop-restart cycle has intervened due to many forces. Despite this impediment, the workforce has delivered engineering feats such as the International Space Station and numerous Shuttle and science missions, which reflect a trend in the early days of the Exploration Age that called for massive infrastructure and matching capital allocations. In the new millennium, the aerospace industry must respond to transforming economic climates, the public will, national agendas, and international possibilities relative to scientific exploration beyond Earth s orbit. Two pressing issues - workforce transition and mission success - are intertwined. As this paper will address, U.S. aerospace must confront related workforce development and industrial base issues head on to take space exploration to the next level. This paper also will formulate specific strategies to equip space engineers to move beyond the seemingly constant start-stop-restart mentality to plan and execute flight projects that actually fly.

  18. Treatment strategies for multiple sclerosis: When to start, when to change, when to stop?

    Multiple sclerosis (MS) is a chronic inflammatory condition of the central nervous system determined by a presumed autoimmune process mainly directed against myelin components but also involving axons and neurons. Acute demyelination shows as clinical relapses that may fully or partially resolve, while chronic demyelination and neuroaxonal injury lead to persistent and irreversible neurological symptoms, often progressing over time. Currently approved disease-modifying therapies are immunomodulatory or immunosuppressive drugs that significantly although variably reduce the frequency of attacks of the relapsing forms of the disease. However, they have limited efficacy in preventing the transition to the progressive phase of MS and are of no benefit after it has started. It is therefore likely that the potential advantage of a given treatment is condensed in a relatively limited window of opportunity for each patient, depending on individual characteristics and disease stage, most frequently but not necessarily in the early phase of the disease. In addition, a sizable proportion of patients with MS may have a very mild clinical course not requiring a disease-modifying therapy. Finally, individual response to existing therapies for MS varies significantly across subjects and the risk of serious adverse events remains an issue, particularly for the newest agents. The present review is aimed at critically describing current treatment strategies for MS with a particular focus on the decision of starting, switching and stopping commercially available immunomodulatory and immunosuppressive therapies.

    Current mechanical key in the motorcycle is prone to bulgary, being stolen or misplaced. Intelligent biometric voice recognition as means to replace this mechanism is proposed as an alternative. The proposed system will decide whether the voice is belong to the user or not and the word utter by the user is ‘On’ or ‘Off’. The decision voice will be sent to Arduino in order to start or stop the engine. The recorded voice is processed in order to get some features which later be used as input to the proposed system. The Mel-Frequency Ceptral Coefficient (MFCC) is adopted as a feature extraction technique. The extracted feature is the used as input to the SVM-based identifier. Experimental results confirm the effectiveness of the proposed intelligent voice recognition and word recognition system. It show that the proposed method produces a good training and testing accuracy, 99.31% and 99.43%, respectively. Moreover, the proposed system shows the performance of false rejection rate (FRR) and false acceptance rate (FAR) accuracy of 0.18% and 17.58%, respectively. In the intelligent word recognition shows that the training and testing accuracy are 100% and 96.3%, respectively.

    Purpose: Despite superior target dose uniformity, helical tomotherapy{sup ®} (HT) may involve a trade-off between longitudinal dose conformity and beam-on time (BOT), due to the limitation of only three available jaw sizes with the conventional HT (1.0, 2.5, and 5.0 cm). The recently introduced dynamic running-start-stop (RSS) delivery allows smaller jaw opening at the superior and inferior ends of the target when a sharp penumbra is needed. This study compared the dosimetric performance of RSS delivery with the fixed jaw HT delivery. Methods: Twenty patient cases were selected and deidentified prior to treatment planning, including 16 common clinical cases (brain, head and neck (HN), lung, and prostate) and four special cases of whole brain with hippocampus avoidance (WBHA) that require a high degree of dose modulation. HT plans were generated for common clinical cases using the fixed 2.5 cm jaw width (HT2.5) and WBHA cases using 1.0 cm (HT1.0). The jaw widths for RSS were preset with a larger size (RSS5.0 vs HT2.5 and RSS2.5 vs HT1.0). Both delivery techniques were planned based on identical contours, prescriptions, and planning objectives. Dose indices for targets and critical organs were compared using dose-volume histograms, BOT, and monitor units. Results: The average BOT was reduced from 4.8 min with HT2.5 to 2.5 min with RSS5.0. Target dose homogeneity with RSS5.0 was shown comparable to HT2.5 for common clinical sites. Superior normal tissue sparing was observed in RSS5.0 for optic nerves and optic chiasm in brain and HN cases. RSS5.0 demonstrated improved dose sparing for cord and esophagus in lung cases, as well as penile bulb in prostate cases. The mean body dose was comparable for both techniques. For the WBHA cases, the target homogeneity was significantly degraded in RSS2.5 without distinct dose sparing for hippocampus, compared to HT1.0. Conclusions: Compared to the fixed jaw HT delivery, RSS combined with a larger jaw width provides faster

    2012-07-01

    To assess the effects of starting or stopping leg cooling on the thermoregulatory responses during exercise, 60 min of cycling exercise at 30% of maximal oxygen uptake was performed under 4 conditions using tube trouser perfused with water at 10 °C; no leg cooling (NC), starting of leg cooling after 30 min of exercise (delayed cooling, DC), continuous leg cooling (CC), and stopping of continuous leg cooling after 30 min of exercise (SC) at an environmental temperature of 28.5 °C. During exercise under the DC conditions, an instantaneous increase in the esophageal temperature (Tes), a suppression of the cutaneous vascular conductance at the forearm (%CVC), and a decrease in the mean skin temperature (Tsk) were observed after leg cooling. The total sweat loss (Δm sw,tot) was lower under the DC than the NC condition. In the SC study, however, the Tes remained constant, while the %CVC increased gradually after leg cooling was stopped, and the Δm sw,tot was greater than that under the CC condition. These results suggest that during exercise, rapid skin cooling of the leg may cause an increase in core temperature, while also enhancing thermal stress. However, stopping skin cooling did not significantly affect the core temperature long-term, because the skin blood flow and sweat rate subsequently increased. © Georg Thieme Verlag KG Stuttgart · New York.

  4. Discontinuing disease-modifying therapy in progressive multiple sclerosis: can we stop what we have started?

    Lonergan, Roisin

    2012-02-01

    Disease-modifying therapy is ineffective in disabled patients (Expanded Disability Status Scale [EDSS] > 6.5) with secondary progressive multiple sclerosis (MS) without relapses, or in primary progressive MS. Many patients with secondary progressive MS who initially had relapsing MS continue to use disease-modifying therapies. The enormous associated costs are a burden to health services. Regular assessment is recommended to guide discontinuation of disease-modifying therapies when no longer beneficial, but this is unavailable to many patients, particularly in rural areas. The objectives of this study are as follows: 1. To observe use of disease-modifying therapies in patients with progressive multiple sclerosis and EDSS > 6.5. 2. To examine approaches used by a group of international MS experts to stopping-disease modifying therapies in patients with secondary progressive MS without relapses. During an epidemiological study in three regions of Ireland (southeast Dublin city, and Wexford and Donegal Counties), we recorded details of disease-modifying therapies in patients with progressive MS and EDSS > 6.5. An e-questionnaire was sent to 26 neurologists with expert knowledge of MS, asking them to share their approach to stopping disease-modifying therapies in patients with secondary progressive MS. Three hundred and thirty-six patients were studied: 88 from southeast Dublin, 99 from Wexford and 149 from Donegal. Forty-four had EDSS > 6.5: 12 were still using disease-modifying therapies. Of the surveyed neurologists, 15 made efforts to stop disease-modifying therapies in progressive multiple sclerosis, but most did not insist. A significant proportion (12 of 44 patients with progressive MS and EDSS > 6.5) was considered to be receiving therapy without benefit. Eleven of the 12 were from rural counties, reflecting poorer access to neurology services. The costs of disease-modifying therapies in this group (>170,000 euro yearly) could be re-directed towards development

    Few individuals commencing antiretroviral therapy (ART) in primary HIV infection (PHI) maintain undetectable viremia after treatment cessation. Associated factors remain unclear given the importance of the phenomenon to cure research. Using CASCADE data of seroconverters starting ART in PHI (≤6 months from seroconversion), we estimated proportions experiencing viral blips (>400 copies followed by HIV-RNA/mL without alteration of regimen) while on ART. We used Cox models to examine the association between time from ART stop to loss of control (2 consecutive measurements >1000 copies per milliliter) and magnitude and frequency of blips while on ART, time from seroconversion to ART, time on ART, adjusting for mean number of HIV-RNA measurements/year while on ART, and other confounders. Seven hundred seventy-eight seroconverters started ART in PHI with ≥3 HIV-RNA measurements. Median interquartile range (IQR) ART duration was 16.2 (8.0-35.9) months, within which we observed 13% with ≥1 blip. Of 228 who stopped ART, 119 rebounded; time to loss of control was associated with longer interval between seroconversion and ART initiation [hazard ratio (HR) = 1.16 per month; 1.04, 1.28], and blips while on ART (HR = 1.71 per blip; 95% confidence interval = 0.94 to 3.10). Longer time on ART (HR = 0.84 per additional month; 0.76, 0.92) was associated with lower risk of losing control. Of 228 stopping ART, 22 (10%) maintained post treatment control (PTC), ie, HIV-RNA HIV viral blips on therapy are associated with subsequent viral rebound on stopping ART among individuals treated in PHI. Longer duration on ART is associated with a greater chance of PTC.

  6. Effects of pushing height on trunk posture and trunk muscle activity when a cart suddenly starts or stops moving.

    2012-01-01

    Unexpected sudden (un)loading of the trunk may induce inadequate responses of trunk muscles and uncontrolled trunk motion. These unexpected perturbations may occur in pushing tasks, when the cart suddenly starts moving (unloading) or is blocked by an obstacle (loading). In pushing, handle height affects the user's working posture, which may influence trunk muscle activity and trunk movement in response to the perturbation. Eleven healthy male subjects pushed a 200 kg cart with handles at shoulder and hip height in a start condition (sudden release of brakes) and a stop condition (bumping into an obstacle). Before the perturbation, the baseline of the trunk inclination, internal moment and trunk extensor muscle activity were significantly higher when pushing at hip height than at shoulder height. After the perturbation, the changes in trunk inclination and internal moment were significantly larger when pushing at shoulder height than at hip height in both conditions. The opposite directions of changes in trunk inclination and internal moment suggest that the unexpected perturbations caused uncontrolled trunk motion. Pushing at shoulder height may impose a high risk of low-back injury due to the low trunk stiffness and large involuntary trunk motion occurring after carts suddenly move or stop.

    The first steps to liberalize NPO guidelines began in the early 1980s and were based more on compassion than science. Infants were allowed to be awakened at 0300 and given clear liquids. Children whose anticipated surgical start times were later than 1200 were allowed to consume clear liquids at 0500. Fortunately, during the past decade, prospective double-blind NPO studies have been performed to provide more scientific input into the development of more humane and rational pediatric NPO guidelines. In this article the author reviews the historical aspects of aspiration pneumonitis, describes the significant findings of recent landmark studies, and presents the NPO guidelines recently promulgated by the Canadian Anaesthetists' Society.

    This paper is on the problem of short-term hydro scheduling (STHS), particularly concerning head-dependent reservoirs under competitive environment. We propose a novel method, based on mixed-integer nonlinear programming (MINLP), for optimising power generation efficiency. This method considers hydroelectric power generation as a nonlinear function of water discharge and of the head. The main contribution of this paper is that discharge ramping constraints and start/stop of units are also considered, in order to obtain more realistic and feasible results. The proposed method has been applied successfully to solve two case studies based on Portuguese cascaded hydro systems, providing a higher profit at an acceptable computation time in comparison with classical optimisation methods based on mixed-integer linear programming (MILP).

    There has been limited attention given to the physiological demands of pushing and pulling, especially in industrially developing countries such as South Africa. Two key factors affecting the physiological demands of these tasks are the hand forces exerted and the start/stop frequency. The purpose of the current study was therefore to investigate the physiological responses to pushing and pulling at various loads and start/stop frequencies. 36 male subjects participated in the study and were required to complete a total of 18 conditions (three techniques: pushing, two- and one-handed pulling; three loads: 200, 350 and 500 kg; and two frequencies: 2 and 4 stops per minute). During each condition the heart rate, oxygen uptake and energy expenditure were measured. Pushing was found to elicit significantly lower responses for all three dependent variables than either form of pulling. The start/stop frequency was also found to have a significant impact on subject responses. The findings of this study indicate that the technique adopted to maneuver loads is critical in determining the physical demands placed on the human operator. Furthermore increasing the frequency of start/stops plays an important role, thus the forces exerted during these two phases are important from a physiological perspective.

  10. When too much is not enough: obsessive-compulsive disorder as a pathology of stopping, rather than starting.

    Directory of Open Access Journals (Sweden)

    Andrea L Hinds

    Full Text Available In obsessive-compulsive disorder (OCD, individuals feel compelled to repeatedly perform security-related behaviors, even though these behaviours seem excessive and unwarranted to them. The present research investigated two alternative ways of explaining such behavior: (1 a dysfunction of activation--a starting problem--in which the level of excitation in response to stimuli suggesting potential danger is abnormally strong; versus (2 a dysfunction of termination--a stopping problem--in which the satiety-like process for shutting down security-related thoughts and actions is abnormally weak.In two experiments, 70 patients with OCD (57 with washing compulsions, 13 with checking compulsions and 72 controls were exposed to contamination cues--immersing a hand in wet diapers--and later allowed to wash their hands, first limited to 30 s and then for as long as desired. The intensity of activation of security motivation was measured objectively by change in respiratory sinus arrythmia. Subjective ratings (e.g., contamination and behavioral measures (e.g., duration of hand washing were also collected.Compared to controls, OCD patients with washing compulsions did not differ significantly in their levels of initial activation to the threat of contamination; however, they were significantly less able to reduce this activation by engaging in the corrective behavior of hand-washing. Further, the deactivating effect of hand-washing in OCD patients with checking compulsions was similar to that for controls, indicating that the dysfunction of termination in OCD is specific to the patient's symptom profile.These results are the first to show that OCD is characterized by a reduced ability of security-related behavior to terminate motivation evoked by potential danger, rather than a heightened initial sensitivity to potential threat. They lend support to the security-motivation theory of OCD (Szechtman & Woody, 2004 and have important implications both for

    Studies are made about the control of the power conditioner over the maximum power point tracking (MPPT) function in a photovoltaic power generation system. The analysis is conducted by means of computer simulation into the effect of a start/stop function added to the control of MPPT and the effect on the generation of power of the setting of parameters in the start/stop function. The reduction in output power due to difference between the actual operation point and the optimum operation point is evaluated by use of a load matching correction factor. In this simulation, it is assumed that the solar cell array consists of 13 rows in 5 parallel columns, is capable of a normal output of 3.149kW, has a panel tilted at 30 degrees, and faces due south. The power conditioner is assumed to be a system rated at 3kVA, equipped with system interconnection and back flow features. As a result, it is learned that the stop voltage should be set at 180V or lower and the steady voltage near 185.5V for a good result and that there is not much need after all for the start/stop technique. 2 refs., 8 figs., 2 tabs.

    Full Text Available While the ‘web as rhizome’ is widely understood, this is rarely demonstrated more clearly than through the link ecologies of blogs. Yet another concept from Deleuze and Guattari, the refrain, could be in many ways as influential in understanding the nature of the web, particularly how the web is invoked through search engines. As Google’s PageRank algorithm is the most effective method of invoking a useful web hierarchy today, it has become both a practical and theoretical focus for the nature of the web itself. This paper aims to show that when blog linkages are used to intentionally influence PageRank, we find we are granted a clear and temporal demonstration of both rhizome and refrain.

  18. When teams can't decide. Are stalemates on your leadership team making you a dictator by default? Stop blaming your people--start fixing the process.

    Science.gov (United States)

    Frisch, Bob

    2008-11-01

    Leadership teams that can't reach consensus wait for the CEO to make the final call--and often are disappointed by the outcome. Frisch calls this phenomenon the dictator-by-default syndrome. Many companies turn to team-building and communication exercises to try to fix the situation. But that won't work, the author argues, because the trouble is not with the people, it's with the decision-making process. Attempting to arrive at a collective preference on the basis of individual opinions is inherently problematic. Once leadership teams realize that voting-system mathematics are the culprit, they can stop wasting time on irrelevant psychological exercises and instead adopt practical measures designed to break the impasse. They must begin by acknowledging the problem and understanding what causes it. When more than two options are on the table, the scene is set for the CEO to become a dictator by default. Even yes-or-no choices present difficulties, because they always include a third, implied alternative: "Neither of the above." When the CEO and the team understand why they have trouble making decisions, they can adopt the following tactics to minimize dysfunction: Clearly articulate the desired outcome, generate a range of options for achieving it, test "fences" (which can be moved) and "walls" (which cannot), surface preferences early, state each option's pros and cons, and devise new options that preserve the best features of existing ones, Teams using such tactics need to adhere to two ground rules. First, they must deliberate confidentially, because a secure climate for conversation allows members to float trial balloons and cut deals. And second, members must be given enough time to study their options and assess the counterarguments. Only then can they achieve genuine alignment.

    The advent of biological therapy has revolutionized inflammatory bowel disease (IBD) care. Nonetheless, not all patients require biological therapy. Selection of patients depends on clinical characteristics, previous response to other medical therapy, and comorbid conditions. Availability, reimbursement guidelines, and patient preferences guide the choice of first-line biological therapy for luminal Crohn's disease (CD). Infliximab (IFX) has the most extensive clinical trial data, but other biological agents (adalimumab (ADA), certolizumab pegol (CZP), and natalizumab (NAT)) appear to have similar benefits in CD. Steroid-refractory, steroid-dependent, or complex fistulizing CD are indications for starting biological therapy, after surgical drainage of any sepsis. For fistulizing CD, the efficacy of IFX for inducing fistula closure is best documented. Unique risks of NAT account for its labeling as a second-line biological agent in some countries. Patients who respond to induction therapy benefit from systematic re-treatment. The combination of IFX with azathioprine is better than monotherapy for induction of remission and mucosal healing up to 1 year in patients who are naïve to both agents. Whether this applies to other agents remains unknown. IFX is also effective for treatment-refractory, moderate, or severely active ulcerative colitis. Patients who have a diminished or loss of response to anti-tumor necrosis factor (TNF) therapy may respond to dose adjustment of the same agent or switching to another agent. Careful consideration should be given to the reasons for loss of response. There are insufficient data to make recommendations on when to stop anti-TNF therapy. Preliminary evidence suggests that a substantial proportion of patients in clinical remission for >1 year, without signs of active inflammation can remain in remission after stopping treatment.

  5. A cognitive model of pathological worry

    Science.gov (United States)

    Hirsch, Colette R.; Mathews, Andrew

    2012-01-01

    We present an evidence-based model of pathological worry in which worry arises from an interaction between involuntary (bottom-up) processes, such as habitual biases in attention and interpretation favouring threat content, and voluntary (top-down) processes, such as attentional control. At a pre-conscious level, these processes influence the competition between mental representations when some correspond to the intended focus of attention and others to threat distracters. Processing biases influence the probability of threat representations initially intruding into awareness as negative thoughts. Worry in predominantly verbal form then develops, influenced by conscious processes such as attempts to resolve the perceived threat and the redirection of attentional control resources to worry content, as well as the continuing influence of habitual processing biases. After describing this model, we present evidence for each component process and for their causal role in pathological worry, together with implications for new directions in the treatment of pathological worry.

    Introduction Older women with ovarian cancer (OC) are less likely to receive guideline concordant treatment. Differences in values and worries about treatment may explain why. Methods Women with OC in 2013–2015 were surveyed about values and worries at the time of initial treatment. Existing values (11 item, e.g., maintaining quality of life) and worries (12 items, e.g., treatment side effects) scales were adapted based on OC literature. Responses were very/somewhat/a little/not at all important or worried. Principal Component Analyses (PCA) identified groups of values and worries that best explained scales' variation. We examined proportions reporting very/somewhat important/worried on ≥1 item in each component by age (older ≥65 years, younger <65 years). Results Of 170 respondents, 42.3%were older. PCA components for values were: functional well-being (3 survey items, proportion of variance explained [PoVE] 26.3%), length of life and sexual functioning (3 items, PoVE 20.1%), attitudes (3 items, PoVE 14.2%), and not becoming a burden (2 items, PoVE 13.7%). PCA components for worries were: economic (4 items, PoVE 27.2%), uncertainty (6 items, PoVE 26.0%), and family impact (2 items, PoVE 16.3%). Older women were less likely to indicate very/somewhat worried to ≥1 item in the economic (51.4% vs 72.4%, p = 0.006), uncertainty (80.6% vs. 98.0%, p = 0.001), and family impact component (55.6% vs. 70.4%, p = 0.03). No other age differences were found. Conclusions While worry during OC treatment decision-making may differ across age groups, values do not. Research should assess how differences in worry might affect OC medical decision-making for older and younger women. PMID:28888542

    Pain-related worry is distinct from, but related to, pain catastrophizing (PC) and anxiety. Worry and its relationship with other variables have been studied in people with chronic pain but not in people with chronic orofacial pain. The authors explored the prevalence of trait, general and pain-related worry and the association of worry with higher pain levels and other variables. The authors assessed people who had a diagnosis of chronic orofacial pain by using nonpain-related trait worry, state anxiety, trait anxiety, PC and pain measures. The participants' answers to an open-ended question about what they were most worried about led to the identification of worry domains, including worry about pain. The authors found that worrying about pain was related significantly to worst and least pain levels, pain interference and pain duration, as well as moderated trait worry in predicting pain interference. Although trait worry was not correlated directly with pain, when moderated by PC, it made substantial contributions in predicting pain interference. Participants with chronic orofacial pain reported experiencing substantial levels of trait worry, anxiety, PC and worry about pain that related to pain ratings directly and indirectly. Clinicians should assess pain-related worry in patients with chronic orofacial pain to understand the effects of worry on pain and functioning. Clinicians could treat these patients more effectively by helping them reduce their levels of pain-related worry and focusing on improved coping.

    Full Text Available The aim of the present study was twofold: 1 to investigate the psychological profile of patients with fibromyalgia syndrome (FS as compared to patients with other chronic pain syndromes (CP and healthy subjects (HS; 2 to examine the associations between anxiety, depression, worry and angry rumination in FS patients. FS patients (N=30, CP patients (N=30 and HS (N=30 completed measurements of anxiety, depression, worry and angry rumination. FS patients showed higher levels of state and trait anxiety, worry and angry rumination than CP patients and HS, and higher levels of depression than HS. Worry and angry rumination were strongly associated in the FS group. FS patients may use worry and rumination as coping strategies to deal with their negative emotional experience, which might impair their emotional wellbeing. Findings from the present study add to our understanding of the psychological profile of FS patients, and have important implications for developing a tailored CBT protocol for pain management in FS patients.

  17. The Dual Effects of Critical Thinking Disposition on Worry

    Science.gov (United States)

    Sugiura, Yoshinori

    2013-01-01

    This study investigated the relationship between disposition (people’s consistent motivation) toward critical thinking (CT) and worrying. In spite of its connection to psychopathology, worry is thought to represent an effort at problem-solving. Moreover, worry has been found to be underpinned by cognitive development, leading us to predict a positive relationship between worry and CT disposition. On the other hand, cognitive behavioral therapy, which involves techniques similar to CT, has been shown to be effective in reducing worrying, suggesting that increasing CT disposition decreases worrying. This study attempted to reconcile these seemingly contrasting predictions about the relationship between CT disposition and worrying by using multiple mediator analysis. A model was proposed wherein the mediators, responsibility to continue thinking and detached awareness of negative thinking, were related to two opposing predictions. The former is thought to lead to enhanced worrying and the latter to reduced worrying, with both positively related to CT disposition. A questionnaire study with university students (N = 760) revealed that CT disposition enhanced worrying by obliging people to continue thinking about a problem, but that it also reduced worrying by enhancing the detached and objective awareness of their negative thoughts. This study thus demonstrated the dual effects of CT disposition on worrying through different mediators. Thus, when enhancing CT disposition, it is important for educators to be aware of possible disadvantages apart from its worry-reducing effect. Future studies should therefore examine the underlying mechanisms of these two effects of CT disposition. PMID:24278160

  2. Should poverty researchers worry about inequality?

    OpenAIRE

    2010-01-01

    The paper constructs a case for arguing that poverty researchers need not worry about inequality (as poverty researchers). It reviews conceptualisations of poverty as essentially relational, a particular reflection of prevailing inequalities. In this approach, people are in poverty because they are less well off than others along important dimensions of wellbeing. As against this view, the paper constructs a case for studying poverty as non-relational. In this approach, people are in poverty ...

  3. Parental overprotection and metacognitions as predictors of worry and anxiety.

    Parental overprotection may have a direct effect on worry through hindering children's exploration experiences and preventing the learning of action-oriented coping strategies (Cheron, Ehrenreich and Pincus, 2009; Nolen-Hoeksema, Wolfson, Mumme and Guskin, 1995) and an indirect effect through fostering the development of maladaptive metacognitions that are associated with the activation of worry and the escalation of anxiety (Wells, 2000). The aim was to investigate the relative contribution of recalled parental overprotection in childhood and metacognitions in predicting current levels of worry. A community sample (n = 301) was administered four self-report instruments to assess parental overprotection, metacognitions, anxiety and worry. Metacognitions were found to predict levels of worry independently of gender, anxiety and parental overprotection. They were also found to predict anxiety independently of gender, worry and parental overprotection. The combination of a family environment perceived to be characterized by overprotection and high levels of maladaptive metacognitions are a risk factor for the development of worry.

  4. Reduced γ–γ time walk to below 50 ps using the multiplexed-start and multiplexed-stop fast-timing technique with LaBr_3(Ce) detectors

    The electronic γ–γ fast-timing technique using arrays consisting of many LaBr_3(Ce) detectors is a powerful method to determine lifetimes of nuclear excited states with a lower limit of about 5 ps. This method requires the determination of the energy-dependent time walk of the zero time which is represented by the centroid of a prompt γ–γ time distribution. The full-energy peak versus full-energy peak prompt response difference which represents the linearly combined mean γ–γ time walk of a fast-timing array consisting of 8 LaBr_3(Ce) detectors was measured using a standard "1"5"2Eu γ-ray source for the energy region of 40–1408 keV. The data were acquired using a “multiplexed-start and multiplexed-stop” analogue electronics circuitry and analysed by employing the generalized centroid difference method. Concerning the cylindrical 1.5 in.×1.5 in. LaBr_3(Ce) crystals which are coupled to the Hamamatsu R9779 photomultiplier tubes, the best fast-timing array time resolution of 202(3) ps is obtained for the two prompt γ lines of "6"0Co by using the leading-edge timing principle. When using the zero-crossover timing principle the time resolution is degraded by up to 30%, dependent on the energy and the shaping delay time of the constant fraction discriminator model Ortec 935. The smallest γ–γ time walk to below 50 ps is obtained by using a shaping delay time of about 17 ns and an optimum “time-walk adjustment” needed for detector output pulses with amplitudes smaller than 400 mV.

    The nuclear nonproliferation regime has many robust measures in place to prevent the acquisition of a nuclear weapon, a key pillar of which is denying or preventing the transfer of technology to specific actors. Additive manufacturing (AM) is a rapidly advancing, not fully understood technology that could dramatically alter the landscape of the safeguarded fuel cycle. However, many of the benefits of AM could also be used to circumvent or defeat current safeguard practices and controls. Because the AM capability is not fully understood, research and integration is necessary early in the technology development stages in order for nonproliferation to remain on the leading edge of discovery and not the tail end of technology deployment.

    2015-10-01

    In light of repeated failures to reach political agreement on effective policies to combat climate change, pro-nuclear environmentalists have set out to reverse the traditionally anti-nuclear inclinations of environmentalists. This essay examines the ideological commitments and assumptions of pro-nuclear environmentalism by performing a critical, historical analysis of the nuclear-environment nexus through the prism of documentary film. We focus on the work and career of documentary filmmaker Rob Stone, whose most recent production, Pandora's Promise (PP) (2013), has emerged as a central statement of this creed. PP actively forges a new political imaginary that replaces the apocalyptic image of nuclear fallout with that of catastrophic climate change. In terms of its rhetorical and visual strategies, however, PP also reveals that pro-nuclear environmentalist arguments have a long lineage. A close study of such continuities reveals a number of political implications that call for reflection as well as caution.

  9. How I Learned to Stop Worrying and Love the SWCX Emission

    Science.gov (United States)

    2011-01-01

    In the last twenty years solar wind change exchange (SWCX) X-ray emission has gone from a significant and irritating background component of unknown origin for astrophysical observations to a field of study in its own right. On one hand, it provides an uncertain offset to observations of extended astrophysical objects and the diffuse X-ray background, and severely compromises the interpretation of many results. On the other hand, SWCX emission has the potential to shed light on physical phenomena in the near-Earth environment and the solar system. In addition, charge exchange emission may prove significant in many other areas of astrophysical diffuse X-ray emission such as supernova remnants. I will present an historical background from the perspective of studying the diffuse X-ray background, cover a variety of SWCX observations and implications, and discuss the realm of possible research and practical applications based on SWCX emission

    There is a natural human tendency and an embedded Western cultural ethos to embrace fatalistic "doomsday" scenarios when trying to predict the future. Environmental concerns are no stranger to these. However, they often lead to counterproductive dialogue and resigned responses. In the case of climate change, I see a troubling narrowing and bifurcation of worldview when it comes to policy options for climate change. As a working climate scientist and public University professor who conducts scientific field research in rural Wisconsin, I've led a number of discussions and presentations on climate change with a diverse range of audiences across the political spectrum. I will discuss what I've learned from these experiences and hear from you about your experiences, both where things have gone great or horribly wrong. It seems that the best experiences occur when we as scientists are focused on what we do best, which is sharing our curiosity about the natural world, maintaining an openness to scholarly debate and learning from your audience with empathy, and expressing our passion for sustained research led by a belief in the potential of humanity to better safeguard and conserve natural resources using scientific approaches. Things go wrong when we fall into the easy traps of promoting doomsday alarmism, injecting personal political bias and elitism, or overstepping authority in areas of policy and economics.

    Directory of Open Access Journals (Sweden)

    Nick Hocking

    2014-01-01

    Full Text Available 'Sinthomosexuality' is Lee Edelman's coinage, combining 'homosexuality' with Lacan's concept of the 'sinthome': the "senseless jouissance" which ties a particular Subject together, binding their Real, Imaginary, and Symbolic aspects into a functional unity called 'I'. At the termination of a successful Lacanian analysis, a subject should have shifted their perspective fundamentally from "believ[ing] in" their sinthome, to simply "identifying with it", no longer expecting it to bear any Symbolic meaning ('No Future', p.37. I read the latest James Bond movie, 'Skyfall', through and against Edelman's work. Bond's symbolic death provides the occasion for a profoundly 'Queer' reinvention of the character – seen in the way that the villain, Javier Bardem's exuberantly 'Queer' rogue agent, holds up a mirror to Bond which Daniel Craig's blue eyes meet without a hint of disavowal. But if something like Edelman's sinthomosexual is embodied in the latest Bond, why does the film ultimately uphold profoundly reactionary fantasies of Britishness?

    The purpose of this study was to examine differences and similarities across ratings of parenting by preadolescents, parents, and observers. Two hundred forty-one preadolescents rated their parents on warmth and harshness. Both mothers and fathers self-reported on these same dimensions, and observers rated each parents' warmth and harshness during a 10 min interaction task with the preadolescent. For the majority of outcomes assessed, the differences between preadolescent, parent, and observer ratings accounted for significant amounts of variance, beyond the levels accounted for by the average of their reports. A replication sample of 929 mother-child dyads provided a similar pattern of results. This methodology can help standardize the study of reporter differences, supports modeling of rater-specific variance as true score, and illustrates the benefits of collecting parenting data from multiple reporters.

  19. Hospitalized elders and family caregivers: a typology of family worry.

    Science.gov (United States)

    2005-01-01

    This qualitative study explored the kinds of worry that family caregivers experience when their older relatives are hospitalized. Little is known about what kinds of worries family caregivers may have in association with the hospitalizations of older relatives. An understanding of the different patterns of family worry may help health care teams intervene more effectively to meet family caregiver's needs by reducing their anxiety. A qualitative descriptive design with Loftland and Loftland (1984) approach for the study of a phenomenon occurring in a social setting was used. A purposeful sample of 10 participants was obtained that included six family caregivers and four nurses. Participants were recruited from two hospitals in the northwest US. Intensive interviews and participant observations were used for data collection, and Loftland and Loftland's (1984) qualitative approach was used for data analysis. Family worry was defined as family caregivers' felt difficulty in fulfilling their roles because of worry. Four categories of family worry were identified as a result of this study: (i) worry about the patient's condition; (ii) worry about the patient's care received from the health care team; (iii) worry about future care for the patient provided by the family caregiver; and (iv) worry about finances. The findings of this pilot study provide nurses with the initial knowledge of the typology of family worry associated with elderly relatives' hospitalizations. The findings of this study may sensitize the nurses to more precisely evaluate family caregivers' worry about their hospitalized elders and provide more effective nursing interventions to improve outcomes of both patients and their family caregivers.

  20. Why START?

    Mendelsohn, J.

    1991-01-01

    Barring some major unexpected downturn in US-Soviet relations, it seems likely that the long-awaited Strategic Arms Reduction Talks (START) treaty will be signed sometime in 1991. Under negotiation for the past nine years, public acceptance and Senate approval of a START treaty will be facilitated by the generally less confrontational East-West relationship which has evolved over that time, by the growing constraints on the US defense budget, and by the obvious merits of the treaty itself. Not only will the nearly complete START treaty be an extremely useful and powerful arms control agreement, it is also decidedly advantageous to US security interests. First and foremost, a START treaty will cap and reduce the steady buildup of nuclear weapons that has characterized the last 30 years of the US-Soviet strategic relationship. As a result of the basic outline originally agreed to at the Reykjavik summit, START will take a 25 to 35 percent bite out of existing nuclear arsenals, impose approximately a 50 percent cut in overall Soviet ballistic missile warheads and throw-weight (lifting power or payload capacity), and produce an exact 50 percent cut in Soviet SS-18 missiles

  2. “My Worries Are Rational, Climate Change Is Not”: Habitual Ecological Worrying Is an Adaptive Response

    Science.gov (United States)

    Verplanken, Bas; Roy, Deborah

    2013-01-01

    Qualifications such as “global warming hysteria” and “energy policy schizophrenia” put forward by some climate change skeptics, usually outside the academic arena, may suggest that people who seriously worry about the environment suffer from psychological imbalance. The present study aimed to refute this thesis. While habitual worrying in general is strongly associated with psychopathological symptoms, in a survey a near-zero correlation was found between habitual ecological worrying and pathological worry. Instead, habitual ecological worrying was associated with pro-environmental attitudes and behaviors, and with a personality structure characterized by imagination and an appreciation for new ideas. The study had sufficient statistical power and measures were valid and reliable. The results confirm that those who habitually worry about the ecology are not only lacking in any psychopathology, but demonstrate a constructive and adaptive response to a serious problem. In the public domain, these findings may contribute to a more rational and less emotional debate on climate change and to the prevention of stigmatization of people who are genuinely concerned about our habitat and are prepared to do something about it (“habitual worriers are not crazy”). In the academic arena this study may contribute to environmental psychology (“habitual worrying is part of a green identity”), as well as to the literature on worry and anxiety (“habitual worrying can be a constructive response”).

    The modern trigger and data acquisition systems that instrument discovery experiments at the Large Hadron Collider (LHC) at CERN are very complex digital systems that select, reduce, and process enormous volumes of data in real-time to match the resources of state-of-the-art distributed computing available to researchers. Never before in particle physics have such powerful digital reconstruction and filtering systems been matched to a world-wide distributed system of computing of unprecedented scale. The goal of these massive aggregate computing systems is to extract as much physical information as possible from collision events at the LHC with well understood selection criteria and biases. Current strategies and future challenges in providing these aggregate real-time and offline computing systems are described.

He contends that present wheeling orders that convert high-voltage wires of generation and transmission companies into 'open access' transmission providers while maintaining their control of dispatch are skewed; rather, the Poolco must charge the same prices for comparable transmission services provided to any customer. Transmission plant must always be dispatched in a least-cost fashion; contracts-for-differences enable customers to hedge against extreme price fluctuations that may arise. Poolco payments should be made to an independent Gridco as compensation for providing its physical grid; necessary revenues must be recovered from Poolco customers. 6 figs

  15. Nurses' worry or concern and early recognition of deteriorating patients on general wards in acute care hospitals: a systematic review.

    Douw, Gooske; Schoonhoven, Lisette; Holwerda, Tineke; Huisman-de Waal, Getty; van Zanten, Arthur R H; van Achterberg, Theo; van der Hoeven, Johannes G

    2015-05-20

    Nurses often recognize deterioration in patients through intuition rather than through routine measurement of vital signs. Adding the 'worry or concern' sign to the Rapid Response System provides opportunities for nurses to act upon their intuitive feelings. Identifying what triggers nurses to be worried or concerned might help to put intuition into words, and potentially empower nurses to act upon their intuitive feelings and obtain medical assistance in an early stage of deterioration. The aim of this systematic review is to identify the signs and symptoms that trigger nurses' worry or concern about a patient's condition. We searched the databases PubMed, CINAHL, Psychinfo and Cochrane Library (Clinical Trials) using synonyms related to the three concepts: 'nurses', 'worry/concern' and 'deterioration'. We included studies concerning adult patients on general wards in acute care hospitals. The search was performed from the start of the databases until 14 February 2014. The search resulted in 4,006 records, and 18 studies (five quantitative, nine qualitative and four mixed-methods designs) were included in the review. A total of 37 signs and symptoms reflecting the nature of the criterion worry or concern emerged from the data and were summarized in 10 general indicators. The results showed that worry or concern can be present with or without change in vital signs. The signs and symptoms we found in the literature reflect the nature of nurses' worry or concern, and nurses may incorporate these signs in their assessment of the patient and their decision to call for assistance. The fact that it is present before changes in vital signs suggests potential for improving care in an early stage of deterioration.

  16. Worry and perceived threat of proximal and distal undesirable outcomes.

    Science.gov (United States)

    Bredemeier, Keith; Berenbaum, Howard; Spielberg, Jeffrey M

    2012-04-01

    Individuals who are prone to worry tend to overestimate the likelihoods and costs of future undesirable outcomes. However, it is unclear whether these relations vary as a function of the timeframe of the event in question. In the present study, 342 undergraduate students completed a self-report measure of worry and rated the perceived probabilities and costs of 40 undesirable outcomes. Specifically, each participant estimated the probability that each of these outcomes would occur within three different timeframes: the next month, the next year, and the next 10 years. We found that the strength of the association between worry and probability estimates was strongest for the most proximal timeframe. Probability estimates were more strongly associated with worry for participants with elevated cost estimates, and this interactive effect was strongest for the most distal timeframe. Implications of these findings for understanding the etiology and treatment of excessive worry are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    This level sets the stage for the design philosophy called “Triadic Game Design” (TGD). This design philosophy can be summarized with the following sentence: it takes two to tango, but it takes three to design a meaningful game or a game with a purpose. Before the philosophy is further explained, this level will first delve into what is meant by a meaningful game or a game with a purpose. Many terms and definitions have seen the light and in this book I will specifically orient at digital games that aim to have an effect beyond the context of the game itself. Subsequently, a historical overview is given of the usage of games with a serious purpose which starts from the moment we human beings started to walk on our feet till our contemporary society. It turns out that we have been using games for all kinds of non-entertainment purposes for already quite a long time. With this introductory material in the back of our minds, I will explain the concept of TGD by means of a puzzle. After that, the protagonist of this book, the game Levee Patroller, is introduced. Based on the development of this game, the idea of TGD, which stresses to balance three different worlds, the worlds of Reality, Meaning, and Play, came into being. Interested? Then I suggest to quickly “press start!”

    Davey, Graham C L; Meeten, F

    2016-12-01

    This paper reviews the cognitive, affective and attentional factors that contribute to individual perseverative worry bouts. We describe how automatic biases in attentional and interpretational processes contribute to threat detection and to the inclusion of negative intrusive thoughts into the worry stream typical of the "what if …?" thinking style of pathological worriers. The review also describes processes occurring downstream from these perceptual biases that also facilitate perseveration, including cognitive biases in beliefs about the nature of the worry process, the automatic deployment of strict goal-directed responses for dealing with the threat, the role of negative mood in facilitating effortful forms of information processing (i.e. systematic information processing styles), and in providing negative information for evaluating the success of the worry bout. We also consider the clinical implications of this model for an integrated intervention programme for pathological worrying. Copyright © 2016 Elsevier B.V. All rights reserved.

    2010-12-01

    Dysfunctional beliefs in obsessive-compulsive disorder (OCD) and worry are thought to contribute to vulnerability and maintenance of pathological anxiety. In this study, five belief domains concerning responsibility/threat estimation, perfectionism, intolerance of uncertainty, importance/control of thoughts and thought-action fusion were examined to see whether they differentially predicted worry and obsession severity in patients with severe OCD. Correlational analysis revealed that perfectionism and intolerance of uncertainty were associated with worry, whereas beliefs in the importance and control of thoughts and thought-action fusion were associated with obsession severity when obsession severity and worry, respectively, were controlled. In regression analyses, thought-action fusion and intolerance of uncertainty predicted OCD severity. The relation between dysfunctional beliefs and specific subtypes of OCD symptoms was also examined. Specific relationships were identified, including perfectionism with ordering, obsessions with control/importance of thoughts and checking and washing with threat estimation.

    To better understand why some people worry more about terrorism compared with others, we measured how much US residents worried about a terrorist event in their area and examined the association of their fears with their concerns about acute and chronic hazards and other correlates. In 2008 (n = 600) and 2010 (n = 651), we performed a random-digit dialing national landline telephone survey. We asked about worries about terrorism and 5 other environmental health hazard issues. We also collected demographic and socioeconomic data. Only 15% worried "a great deal" about a terrorist event in their area and 18% to 33% were greatly concerned about other environmental issues. Fear about acute hazard events was a stronger predictor of a great deal of concern about terrorism than were age, race/ethnicity, gender, educational achievement, and other correlates. Those who worried most about acute environmental health hazard events were most likely to worry about terrorism. Also, those who were older, poorer, Blacks, or Latinos, or who lived in populous urban areas felt they were most vulnerable to terrorist attacks. We recommend methods to involve US citizens as part of disaster planning.

    Two dyadic studies investigated interpersonal worry regulation in heterosexual relationships. In Study 1, we video-recorded 40 romantic couples discussing shared concerns. Male partners’ worry positively predicted female partners’ interpersonal calming attempts, and negatively predicted female partners’ interpersonal alerting attempts (i.e., attempts to make their partners appreciate the seriousness of concerns). Video-cued recall data also indicated that changes in partner A’s worry over time positively predicted partner B’s motivation to reduce partner A’s worry, and that this effect was stronger when B was the female partner. Study 2 was a dyadic survey of 100 couples. Individual differences in partner A’s negative affect were positive predictors of partner B’s interpersonal calming, and individual differences in partner A’s expressive suppression were negative predictors of partner B’s interpersonal calming. Further, individual differences in male partners’ expressivity were significant positive predictors of female partners’ interpersonal calming, and individual differences in male partners’ reappraisal were significant positive predictors of female partners’ interpersonal alerting. These findings suggest that interpersonal worry regulation relates to partners’ expression and intrapersonal regulation of worry, but not equally for men and women. PMID:26882336

  8. Investigation of RADTRAN Stop Model input parameters for truck stops

    International Nuclear Information System (INIS)

    Griego, N.R.; Smith, J.D.; Neuhauser, K.S.

    1996-01-01

    RADTRAN is a computer code for estimating the risks and consequences as transport of radioactive materials (RAM). RADTRAN was developed and is maintained by Sandia National Laboratories for the US Department of Energy (DOE). For incident-free transportation, the dose to persons exposed while the shipment is stopped is frequently a major percentage of the overall dose. This dose is referred to as Stop Dose and is calculated by the Stop Model. Because stop dose is a significant portion of the overall dose associated with RAM transport, the values used as input for the Stop Model are important. Therefore, an investigation of typical values for RADTRAN Stop Parameters for truck stops was performed. The resulting data from these investigations were analyzed to provide mean values, standard deviations, and histograms. Hence, the mean values can be used when an analyst does not have a basis for selecting other input values for the Stop Model. In addition, the histograms and their characteristics can be used to guide statistical sampling techniques to measure sensitivity of the RADTRAN calculated Stop Dose to the uncertainties in the stop model input parameters. This paper discusses the details and presents the results of the investigation of stop model input parameters at truck stops

  9. Optimally Stopped Optimization

    Science.gov (United States)

    Vinci, Walter; Lidar, Daniel

    We combine the fields of heuristic optimization and optimal stopping. We propose a strategy for benchmarking randomized optimization algorithms that minimizes the expected total cost for obtaining a good solution with an optimal number of calls to the solver. To do so, rather than letting the objective function alone define a cost to be minimized, we introduce a further cost-per-call of the algorithm. We show that this problem can be formulated using optimal stopping theory. The expected cost is a flexible figure of merit for benchmarking probabilistic solvers that can be computed when the optimal solution is not known, and that avoids the biases and arbitrariness that affect other measures. The optimal stopping formulation of benchmarking directly leads to a real-time, optimal-utilization strategy for probabilistic optimizers with practical impact. We apply our formulation to benchmark the performance of a D-Wave 2X quantum annealer and the HFS solver, a specialized classical heuristic algorithm designed for low tree-width graphs. On a set of frustrated-loop instances with planted solutions defined on up to N = 1098 variables, the D-Wave device is between one to two orders of magnitude faster than the HFS solver.

What will happen tomorrow when Chinese and Indian people will reach the same energy consumption levels as people of western countries? Is it too late to reverse the trend? If solar energy is the long-term solution, what can we do in the meantime? The author presents the conditions we must fulfill to keep the Earth in a good environmental condition: 1 - a brief story of energy; 2 - the climatic changes and their secrets; 3 - the greenhouse effect: necessary for life but worrying for the future; 4 - the energy demand and the stakes; 2 - fossil fuels: abundance or shortage? 6 - can we fight against greenhouse gases? 7 - the nuclear energy (reactors and wastes management); 8 - the renewable energies: a necessary contribution at the century scale and the unique answer at the millennium scale; 9 - the time of main choices is not so far; 10 - two questions (energy demand and climatic change) and a unique answer (sustainable development).

    Gauge mediated supersymmetry breaking (GMSB) is an elegant mechanism to transmit supersymmetry breaking from the hidden to the MSSM observable sector, which solves the supersymmetric flavor problem. However, the smallness of the generated stop mixing requires superheavy stops to reproduce the experimental value of the Higgs mass. A possible way out is to extend the MSSM Higgs sector with singlets and/or triplets providing extra tree-level corrections to the Higgs mass. Singlets will not get any soft mass from GMSB and triplets will contribute to the ρ parameter which could be an issue. In this paper we explore the second possibility by introducing extra supersymmetric triplets with hypercharges Y=(0,±1), with a tree-level custodial SU(2){sub L}⊗SU(2){sub R} global symmetry in the Higgs sector protecting the ρ parameter: a supersymmetric generalization of the Georgi-Machacek model, dubbed as supersymmetric custodial triplet model (SCTM). The renormalization group running from the messenger to the electroweak scale mildly breaks the custodial symmetry. We will present realistic low-scale scenarios (with the NLSP being a Bino-like neutralino or the right-handed stau) based on general (non-minimal) gauge mediation and consistent with all present experimental data. Their main features are: i) Light (∼1 TeV) stops; ii) Exotic couplings (H{sup ±}W{sup ∓}Z and H{sup ±±}W{sup ∓}W{sup ∓}) absent in the MSSM and proportional to the triplets VEV, v{sub Δ}; and, iii) A possible (measurable) universality breaking of the Higgs couplings λ{sub WZ}=r{sub WW}/r{sub ZZ}≠1.

    A secondary data analysis of the National Commission on Children: 1990 Survey of Parents and Children was conducted with a subsample of 457 parent-teen pairs who responded to the "worry about AIDS" question. The teen's worry about contracting AIDS was associated with race, parent's education, the amount of discipline from the parent for engaging in sex, the teen's desire to talk to the parent about the problem of sex, the teen's rating of the neighborhood as a safe place to grow up, whether the parent listened to the teen's telephone interview, and the parent's response to whether his or her teen had a history of sexually transmitted disease. Of the parent-teen pairs in the subsample, 46% (N = 210) agreed in their responses about worry. Agreement was more frequent among the parent-teen pairs when compared to randomly constructed surrogate pairs. Dyadic analysis supported a family system view of perceived susceptibility.

    Full Text Available This book on writing grounded theory is intended for the empirical GT researcher who wants to pursue his/her research until publication. It is the first book devoted entirely to such a crucial issue as writing grounded theory. Thus, Stop, Write: Writing Grounded Theory, is a practical book that fills a gap in GT methodology. In the first chapter of the book, Dr. Glaser says, “Stop unending conceptualization, unending data coverage, and unending listening to others who would egg you on with additional data, ideas and/or requirements or simply wait too long”. The book teaches the reader how to actually write a grounded theory by “simply” writing up the sorted memos. This requires efficient sorting that is dealt with in chapter two on Sorting Memos, which includes precious repetition from Theoretical Sensitivity (1978. How writing can be done effectively is outlined in chapter three The Working Paper. Then follows chapter four on how to rework the first draft with the different tasks of editing for language and professionalism. Thereafter Dr. Glaser discusses Writing Problems in chapter five where he gives useful guidance on how to overcome writing blocks and problems with supervisors and dissertation committees. The book also deals with publishing and with collaboration as experienced between Barney Glaser and the cofounder of grounded theory, Anselm Strauss.

    Gauge mediated supersymmetry breaking (GMSB) is an elegant mechanism to transmit supersymmetry breaking from the hidden to the MSSM observable sector, which solves the supersymmetric flavor problem. However the smallness of the generated stop mixing requires superheavy stops to reproduce the experimental value of the Higgs mass. Two possible ways out are: i) To extend GMSB by direct superpotential messenger-MSSM Yukawa couplings to generate sizeable mixing, thus reintroducing the flavor problem; ii) To extend the MSSM Higgs sector with singlets and/or triplets providing extra tree-level corrections to the Higgs mass. Singlets will not get any soft mass from GMSB and triplets will contribute to the $\\rho$ parameter which could be an issue.

    Modified Bethe-Bloch stopping power theory permits fairly accurate calculation of energy losses over a broad interval of projectile velocity v = νc insofar as several parameters appearing in the revised Bethe-Bloch formula have been corectly evaluated. Since the parameters cannot in general be ascertained by calculation from first principles, fits of theory to measurement remain the best method of evaluation. The parameters alluded to are: the target mean excitation energy; the shell correction scaling parameters; the composite single free parameter of the Barkas (projectile-z 3 ) effect correction formalism, and the strength of the correction term; the high velocity density effect correction parameter; and the low velocity charge state parameter. These parameters are discussed

    This study examined associations between adult attachment dimensions, perceived health status and worrying (coping strategy with chronic pain), and explored whether worrying mediated observed relationships between attachment dimensions and health outcomes within a sample of 128 Portuguese female fibromyalgia patients. Physical health status was inversely correlated with dependence and worrying; mental health status was positively correlated with trust, and inversely related to attachment-related ambivalence, dependence and worrying. Finally, worrying mediated relationships between dependence and both physical and mental health status; moreover, worrying partially mediated the relationship between ambivalence and mental health status. Implications of the findings are discussed.

    Full Text Available Aim: Alopecia Areata (AA is a type of hair loss that has been considered to have associations with various psychiatric disorders. In this study, we aimed to compare pathological worry levels between patients with AA and healthy controls (HC. Material and Method: Sixty-three patients with AA and 90 HCs were included in the present study after applying inclusion and exclusion criteria. The socio-demographic characteristics, some clinical characteristics, and the scores from the Penn State Worry Questionnaire (PSWQ were compared between groups. Results: The demographic characteristics were found to be similar between groups except for gender. The family history of AA was significantly higher in the AA group. The mean score of PSWQ in the AA group was 44.02 ± 11.59, compared to 39.71 ± 7.77 in the HC group. The mean score of PSWQ was significantly higher in the AA group (t=-3.27, p= 0.001.Discussion: The present study is the first to compare pathological worry between patients with AA and HCs. We suggest that pathological worry should be more thoroughly investigated in patients with AA to improve their quality of life. Also, this can be an effective approach to targeting the patients who may develop anxiety disorder.

    2016-12-01

    Parents play a critical role in preventing crashes among teens. Research of parental perceptions and concerns regarding teen driving safety is limited. We examined results from the 2013 Summer ConsumerStyles survey that queried parents about restrictions placed on their teen drivers, their perceived level of "worry" about their teen driver's safety, and influence of parental restrictions regarding their teen's driving. We produced frequency distributions for the number of restrictions imposed, parental "worry," and influence of rules regarding their teen's driving, reported by teen's driving license status (learning to drive or obtained a driver's license). Response categories were dichotomized because of small cell sizes, and we ran separate log-linear regression models to explore whether imposing all four restrictions on teen drivers was associated with either worry intensity ("a lot" versus "somewhat, not very much or not at all") or perceived influence of parental rules ("a lot" versus "somewhat, not very much or not at all"). Among the 456 parent respondents, 80% reported having restrictions for their teen driver regarding use of safety belts, drinking and driving, cell phones, and text messaging while driving. However, among the 188 parents of licensed teens, only 9% reported having a written parent-teen driving agreement, either currently or in the past. Worrying "a lot" was reported less frequently by parents of newly licensed teens (36%) compared with parents of learning teens (61%). Parents report having rules and restrictions for their teen drivers, but only a small percentage formalize the rules and restrictions in a written parent-teen driving agreement. Parents worry less about their teen driver's safety during the newly licensed phase, when crash risk is high as compared to the learning phase. Further research is needed into how to effectively support parents in supervising and monitoring their teen driver. Published by Elsevier Ltd.

  7. Has Human Evolution Stopped?

    Directory of Open Access Journals (Sweden)

    Alan R. Templeton

    2010-07-01

    Full Text Available It has been argued that human evolution has stopped because humans now adapt to their environment via cultural evolution and not biological evolution. However, all organisms adapt to their environment, and humans are no exception. Culture defines much of the human environment, so cultural evolution has actually led to adaptive evolution in humans. Examples are given to illustrate the rapid pace of adaptive evolution in response to cultural innovations. These adaptive responses have important implications for infectious diseases, Mendelian genetic diseases, and systemic diseases in current human populations. Moreover, evolution proceeds by mechanisms other than natural selection. The recent growth in human population size has greatly increased the reservoir of mutational variants in the human gene pool, thereby enhancing the potential for human evolution. The increase in human population size coupled with our increased capacity to move across the globe has induced a rapid and ongoing evolutionary shift in how genetic variation is distributed within and among local human populations. In particular, genetic differences between human populations are rapidly diminishing and individual heterozygosity is increasing, with beneficial health effects. Finally, even when cultural evolution eliminates selection on a trait, the trait can still evolve due to natural selection on other traits. Our traits are not isolated, independent units, but rather are integrated into a functional whole, so selection on one trait can cause evolution to occur on another trait, sometimes with mildly maladaptive consequences.

  9. Worry, problem elaboration and suppression of imagery: the role of concreteness.

    Science.gov (United States)

    Stöber, J

    1998-01-01

    Both lay concept and scientific theory claim that worry may be helpful for defining and analyzing problems. Recent studies, however, indicate that worrisome problem elaborations are less concrete than worry-free problem elaborations. This challenges the problem solving view of worry because abstract problem analyses are unlikely to lead to concrete problem solutions. Instead the findings support the avoidance theory of worry which claims that worry suppresses aversive imagery. Following research findings in the dual-coding framework [Paivio, A. (1971). Imagery and verbal processes. New York: Holt, Rhinehart and Winston; Paivio, A. (1986). Mental representations: a dual coding approach. New York: Oxford University Press.], the present article proposes that reduced concreteness may play a central role in the understanding of worry. First, reduced concreteness can explain how worry reduces imagery. Second, it offers an explanation why worrisome problem analyses are unlikely to arrive at solutions. Third, it provides a key for the understanding of worry maintenance.

    Some fear that provoking widespread worry about climate change may harm mental health. The Regional Wellbeing Survey, a large study of health, well-being and life in rural and regional Australia, examined climate change worry and attitudes. Most respondents were worried about climate change and agreed that fossil fuel use causes global warming, but there was no evidence to suggest that worry about climate change is linked to mental health in the general population.

  11. Generalized anxiety disorder and online intelligence: A phenomenological account of why worrying is unhelpful

    OpenAIRE

    Meynen, Gerben

    2011-01-01

    Worrying is the central feature of generalized anxiety disorder (GAD). Many people worry from time to time, but in GAD the worrying is prolonged and difficult to control. Worrying is a specific way of coping with perceived threats and feared situations. Meanwhile, it is not considered to be a helpful coping strategy, and the phenomenological account developed in this paper aims to show why. It builds on several phenomenological notions and in particular on Michael Wheeler's application of the...

    Nitrogen pollution is one of the main threats to the environment now in the Netherlands as well as other parts of Europe. In order to address the main gaps on the issues of nitrogen pollution related to the local scale, the Ministries of Housing, Physical Planning and Environment (VROM) and of Agriculture, Nature Management and Fisheries (LNV) have initiated a research programme, the Dutch Nitrogen Research Programme (STOP), which aims to provide a scientific basis to develop and implement policy on a local scale for the realisation and conservation of the EHS ('Dutch Mainframe of Natural Landscapes'). The results of the programme show that the description of emissions from manure in the field is difficult to describe and show large uncertainties. On the contrary, emissions from housings could be modelled well, if local actual data were available. The OPS model to describe the dispersion and deposition was evaluated with the measurements and the limitations were quantified. It appears that the model works well on the long term, whereas on the short term (hours) and short distance (tenths of meters) there is large uncertainty, especially in complex terrain. Critical loads for nitrogen for ecosystems were evaluated. Furthermore, the effect of management options was quantified. A method to determine critical loads as a function of soil conditions, such as acidification and water availability was derived. This resulted in a combination of the soil model SMART and the so-called 'nature planner' (Natuurplanner). It was concluded that the combination of SMART, the nature planner and OPS provide a good tool to develop and support policy on the local scale. 4 refs

  14. Worrying about the LHC, a lesson from astrophysics?

    CERN Multimedia

    CERN. Geneva

    2008-01-01

    To worry about the LHC is a popular sport. I shall share my own worries, hopefully original, and do it via a parable (for this method, I can quote earlier authors). The parable concerns a topic in astrophysics (gamma-ray bursts) which happens to be a simple exercise --but quite an interesting one-- on elementary particle-physics and beam dynamics, topics not unrelated to the LHC. Though most of the talk will be dedicated to the physics and, in particular, to its recent developments, the allegory will allow me to detect what, I shall argue, may be dangerous 'viruses' invading science. I do not have the decisive antidotes, but I shall discuss some possible ones.

  15. Worry spreads: interpersonal transfer of problem-related anxiety.

    Science.gov (United States)

    Parkinson, Brian; Simons, Gwenda

    2012-01-01

    This paper distinguishes processes potentially contributing to interpersonal anxiety transfer, including object-directed social appraisal, empathic worry, and anxiety contagion, and reviews evidence for their operation. We argue that these anxiety-transfer processes may be exploited strategically when attempting to regulate relationship partners' emotion. More generally, anxiety may serve as either a warning signal to other people about threat (alerting function) or an appeal for emotional support or practical help (comfort-seeking function). Tensions between these two interpersonal functions may account for mutually incongruent interpersonal responses to expressed anxiety, including mistargeted interpersonal regulation attempts. Because worry waxes and wanes over time as a function of other people's ongoing reactions, interpersonal interventions may help to alleviate some of its maladaptive consequences.

  16. Relativistic theory of stopping for heavy ions

    Lindhard, J.; So/rensen, A.H.

    1996-01-01

    We calculate the electronic stopping power and the corresponding straggling for ions of arbitrary charge number, penetrating matter at any relativistic energy. The stopping powers are calculated by a simple method. Its starting point is the deviation of the precise theory from first-order quantum perturbation. We show that this deviation can be expressed in terms of the transport cross section, σ tr , for scattering of a free electron by the ion. In the nonrelativistic case the deviation is precisely the Bloch correction to Bethe close-quote s formula; we look into the nonrelativistic case in order to clarify both some features of our method and a seeming paradox in Rutherford scattering. The corresponding relativistic correction is obtained from σ tr for scattering of a Dirac electron in the ion potential. Here, the major practical advantage of the method shows up; we need not find the scattering distribution, but merely a single quantity, σ tr , determined by differences of successive phase shifts. For a point nucleus our results improve and extend those of Ahlen. Our final results, however, are based on atomic nuclei with standard radii. Thereby, the stopping is changed substantially already for moderate values of γ=(1-v 2 /c 2 ) -1/2 . An asymptotic saturation in stopping is obtained. Because of finite nuclear size, recoil corrections remain negligible at all energies. The average square fluctuation in energy loss is calculated as a simple fluctuation cross section for a free electron. The fluctuation in the relativistic case is generally larger than that of the perturbation formula, by a factor of ∼2 endash 3 for heavy ions. But the finite nuclear radius leads to a strong reduction at high energies and the elimination of the factor γ 2 belonging to point nuclei. copyright 1996 The American Physical Society

    Modern health worries (MHWs) are widespread in modern societies. MHWs were connected to both negative and positive psychological characteristics in previous studies. The study aimed to investigate the relationships among intuitive-experiential information processing style, spirituality, MHWs, and psychological well-being. Members of the Hungarian Skeptic Society (N = 128), individuals committed to astrology (N = 601), and people from a non-representative community sample (N = 554) completed questionnaires assessing intuitive-experiential information processing style, spirituality, modern health worries (MHWs), and psychological well-being. Astrologers showed higher levels of spirituality, intuitive-experiential thinking, and modern health worries than individuals from the community sample; and skeptics scored even lower than the latter group with respect to all three constructs. Within the community sample, medium level connections between measures of spirituality and the experiential thinking style, and weak to medium level correlations between spirituality and MHWs were found. The connection between MHWs and experiential thinking style was completely mediated by spirituality. Individuals with higher levels of spirituality are particularly vulnerable to overgeneralized messages on health related risks. Official communication of potential risks based on rational scientific reasoning is not appropriate to persuade them as it has no impact on the intuitive-experiential system. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    We present the Biological Observation Matrix (BIOM, pronounced "biome") format: a JSON-based file format for representing arbitrary observation by sample contingency tables with associated sample and observation metadata. As the number of categories of comparative omics data types (collectively, the "ome-ome") grows rapidly, a general format to represent and archive this data will facilitate the interoperability of existing bioinformatics tools and future meta-analyses. The BIOM file format is supported by an independent open-source software project (the biom-format project), which initially contains Python objects that support the use and manipulation of BIOM data in Python programs, and is intended to be an open development effort where developers can submit implementations of these objects in other programming languages. The BIOM file format and the biom-format project are steps toward reducing the "bioinformatics bottleneck" that is currently being experienced in diverse areas of biological sciences, and will help us move toward the next phase of comparative omics where basic science is translated into clinical and environmental applications. The BIOM file format is currently recognized as an Earth Microbiome Project Standard, and as a Candidate Standard by the Genomic Standards Consortium.

    We cross-match 3XMM, WISE and FIRST/NVSS to create the largest-to-date mid-IR, X-ray, and radio (MIXR) sample of galaxies and AGN. We use MIXR to triage sources and efficiently and accurately pre-classify them as star-forming galaxies or AGN, and to highlight bias and shortcomings in current AGN sample selection methods, paving the way for the next generation of instruments. Our results highlight key questions in AGN science, such as the need for a re-definition of the radio-loud/radio-quiet classification, and our observed lack of correlation between the kinetic (jet) and radiative (luminosity) output in AGN, which has dramatic potential consequences on our current understanding of AGN accretion, variability and feedback.

    Full Text Available It has been found, that despite the improvement of the objective health indicators, people's subjective perception of health is that health indicators are getting worse (Barsky A.J., 1988, which is one of the reasons why a new term “modern health worries” is coming into use in medical literature (Petrie K.J., Wessely S., 2002. People are worried and scared of the effect of new high tech innovations (effect of cell phone radiation, environmental pollution, ozone layer depletion, etc., changes in manufacturing of food products (genetically modified food, food concentrates etc.. Nowadays, many people, being worried about their health, turn to new eating habits (veganism, defend themselves against various innovations in the health system (vaccination, etc. It could be defined as fear of consequences of scientific progress. The reason of fear is not only the misunderstanding of scientific innovations. Quite often, it is a belief in pseudoscientific theories (for example, “conspiracy” or belief in the paranormal phenomena (karma violations, disruption of the cosmic plan. In a part of cases protesters against vaccines and genetically modified food belong to new religious movements which are based on belief in the paranormal and magical thinking.

    Worry, social anxiety, and depressive symptoms are dimensions that have each been linked to heterogeneous problems in interpersonal functioning. However, the relationships between these symptoms and interpersonal difficulties remain unclear given that most studies have examined diagnostic categories, not accounted for symptoms' shared variability due to general distress, and investigated only interpersonal problems (neglecting interpersonal traits, interpersonal goals, social behavior in daily life, and reports of significant others). To address these issues, students (Study 1; N=282) endorsed symptoms and interpersonal circumplex measures of traits and problems, as well as event-contingent social behaviors during one week of naturalistic daily interactions (N=184; 7,036 records). Additionally, depressed and anxious patients (N=47) reported symptoms and interpersonal goals in a dyadic relationship, and significant others rated patients' interpersonal goals and impact (Study 2). We derived hypotheses about prototypical interpersonal features from theories about the functions of particular symptoms and social behaviors. As expected, worry was uniquely associated with prototypically affiliative tendencies across all self-report measures in both samples, but predicted impacting significant others in unaffiliative ways. As also hypothesized, social anxiety was uniquely and prototypically associated with low dominance across measures, and general distress was associated with cold-submissive tendencies. Findings for depressive symptoms provided less consistent evidence for unique prototypical interpersonal features. Overall, results suggest the importance of multimethod assessment and accounting for general distress in interpersonal models of worry, social anxiety, and depressive symptoms. Copyright © 2015.

  8. Probing Light Stops with Stoponium

    Batell, Brian

    2015-01-01

    We derive new limits on light stops from diboson resonance searches in the $\\gamma\\gamma$, $Z \\gamma$, $ZZ$, $WW$ and $hh$ channels from the first run of the LHC. If the two-body decays of the light stop are mildly suppressed or kinematically forbidden, stoponium bound states will form in $pp$ collisions and subsequently decay via the pair annihilation of the constituent stops to diboson final states, yielding striking resonance signatures. Remarkably, we find that stoponium searches are highly complementary to direct collider searches and indirect probes of light stops such as Higgs coupling measurements. Using an empirical quarkonia potential model and including the first two $S$-wave stoponium states, we find that in the decoupling limit $m_{\\widetilde t_1} \\lesssim 130$ GeV is excluded for any value of the stop mixing angle and heavy stop mass by the combination of the latest resonance searches and the indirect constraints. The $\\gamma \\gamma$ searches are the most complementary to the indirect constraint...

  9. Second stop and sbottom searches with a stealth stop

    The top squarks (stops) may be the most wanted particles after the Higgs boson discovery. The searches for the lightest stop have put strong constraints on its mass. However, there is still a search gap in the low mass region if the spectrum of the stop and the lightest neutralino is compressed. In that case, it may be easier to look for the second stop since naturalness requires both stops to be close to the weak scale. The current experimental searches for the second stop are based on the simplified model approach with the decay modes t̃{sub 2}→t̃{sub 1}Z and t̃{sub 2}→t̃{sub 1}h. However, in a realistic supersymmetric spectrum there is always a sbottom lighter than the second stop, hence the decay patterns are usually more complicated than the simplified model assumptions. In particular, there are often large branching ratios of the decays t̃{sub 2}→b̃{sub 1}W and b̃{sub 1}→t̃{sub 1}W as long as they are open. The decay chains can be even more complex if there are intermediate states of additional charginos and neutralinos in the decays. By studying several MSSM benchmark models at the 14 TeV LHC, we point out the importance of the multi-W final states in the second stop and the sbottom searches, such as the same-sign dilepton and multilepton signals, aside from the traditional search modes. The observed same-sign dilepton excesses at LHC Run 1 and Run 2 may be explained by some of our benchmark models. We also suggest that the vector boson tagging and a new kinematic variable may help to suppress the backgrounds and increase the signal significance for some search channels. Due to the complex decay patterns and lack of the dominant decay channels, the best reaches likely require a combination of various search channels at the LHC for the second stop and the lightest sbottom.

    To reduce colorectal cancer (CRC) screening disparities, it is important to understand correlates of different types of cancer worry among ethnically diverse individuals. The current study examined the prevalence of three types of cancer worry (i.e., general cancer worry, CRC-specific worry, and worry about CRC test results) as well as sociodemographic and health-related predictors for each type of cancer worry. Participants were aged 50-75, at average CRC risk, nonadherent to CRC screening guidelines, and enrolled in a randomized controlled trial to increase CRC screening. Participants completed a baseline questionnaire assessing sociodemographics, health beliefs, healthcare experiences, and three cancer worry measures. Associations between study variables were examined with separate univariate and multivariable logistic regression models. Responses from a total of 416 participants were used. Of these, 47% reported experiencing moderate-to-high levels of general cancer worry. Predictors of general cancer worry were salience and coherence (aOR = 1.1, 95% CI [1.0, 1.3]), perceived susceptibility (aOR = 1.2, 95% CI [1.1, 1.3), and social influence (aOR = 1.1, 95% CI [1.0, 0.1]). Fewer (23%) reported moderate-to-high levels of CRC-specific worry or CRC test worry (35%). Predictors of CRC worry were perceived susceptibility (aOR = 1.4, 95% CI [1.3, 1.6]) and social influence (aOR = 1.1, 95% CI [1.0, 1.2]); predictors of CRC test result worry were perceived susceptibility (aOR = 1.2, 95% CI [1.1, 1.3) and marital status (aOR = 2.0, 95% CI [1.1, 3.7] for married/partnered vs. single and aOR = 2.3, 95% CI [1.3, 4.1] for divorced/widowed vs. single). Perceived susceptibility consistently predicted the three types of cancer worry, whereas other predictors varied between cancer worry types and in magnitude of association. The three types of cancer worry were generally predicted by health beliefs, suggesting potential malleability. Future research should include multiple

    The aim of the study was to explore the worries, safety behaviors, and perceived difficulties in keeping children safe at home in a purposive sample of low-income, predominantly non-English speaking mothers as a foundation for later nursing interventions. This study was a qualitative, descriptive design with content analysis to identify maternal concerns, behaviors, and perceptions of home safety as part of a larger study. Eighty-two mothers, 64% of whom were monolingual Spanish-speakers, responded in writing to three semistructured interview questions. When mothers were unable to read and write the researcher wrote the responses, then read the content aloud for verification. A standardized probe for each question was posed to obtain richer responses. Data management included use of the software program NUD*IST and coding analyses following the Miles and Huberman guidelines (1994). Interpretations were translated into English for this report. The major worries were falling, health, kidnapping, and being hit by a car. The leading maternal behaviors were coded as being physically, verbally, and environmentally preventive. Mothers said that it was their role to provide safety, and that this role could be wearisome, such that constant supervision was difficult. Low-income mothers described their worries for their 1 to 4 year-old children, explored their behaviors for preventing injury, and discussed what made keeping children from harm difficult. Understanding how mothers keep children safe, the barriers to home safety, and effective safety behaviors are important to the health of children. The clinical relevance of this study includes building trust as clinicians plan assessment, intervention and evaluation of home safety to encourage dialog about concerns, safety behaviors, and barriers to keeping children from injury.

  14. Worry experienced during the 2015 Middle East Respiratory Syndrome (MERS pandemic in Korea.

    Directory of Open Access Journals (Sweden)

    Jun-Soo Ro

    Full Text Available Korea failed in its risk communication during the early stage of the Middle East Respiratory Syndrome (MERS outbreak; consequently, it faced difficulties in managing MERS, while disease-related worry increased. Disease-related worry can help disease prevention and management, but can also have a detrimental effect. This study measured the overall level of disease-related worry during the MERS outbreak period in Korea and the influencing factors and levels of disease-related worry during key outbreak periods.The cross-sectional survey included 1,000 adults who resided in Korea. An ordinal logistic regression was performed for the overall level of MERS-related worry, and influencing factors of worry were analyzed. A reliability test was performed on the levels of MERS-related worry during key outbreak periods.The overall level of MERS-related worry was 2.44. Multivariate analysis revealed that women and respondents w very poor subjective health status had higher levels of worry. Respondents with very high stress in daily life had higher levels of worry than those who reported having little stress. The reliability test results on MERS-related worry scores during key outbreak periods showed consistent scores during each period.Level of worry increased in cases having higher perceived susceptibility and greater trust in informal information, while initial stage of outbreak was closely associated with that at later stages. These findings suggest the importance of managing the level of worry by providing timely and accurate disease-related information during the initial stage of disease outbreak.

    Introduction Parents play a critical role in preventing crashes among teens. Research of parental perceptions and concerns regarding teen driving safety is limited. We examined results from the 2013 Summer ConsumerStyles survey that queried parents about restrictions placed on their teen drivers, their perceived level of “worry” about their teen driver’s safety, and influence of parental restrictions regarding their teen’s driving. Methods We produced frequency distributions for the number of restrictions imposed, parental “worry,” and influence of rules regarding their teen’s driving, reported by teen’s driving license status (learning to drive or obtained a driver’s license). Response categories were dichotomized because of small cell sizes, and we ran separate log-linear regression models to explore whether imposing all four restrictions on teen drivers was associated with either worry intensity (“a lot” versus “somewhat, not very much or not at all”) or perceived influence of parental rules (“a lot” versus “somewhat, not very much or not at all”). Results Among the 456 parent respondents, 80% reported having restrictions for their teen driver regarding use of safety belts, drinking and driving, cell phones, and text messaging while driving. However, among the 188 parents of licensed teens, only 9% reported having a written parent-teen driving agreement, either currently or in the past. Worrying “a lot” was reported less frequently by parents of newly licensed teens (36%) compared with parents of learning teens (61%). Conclusions and Practical Applications Parents report having rules and restrictions for their teen drivers, but only a small percentage formalize the rules and restrictions in a written parent-teen driving agreement. Parents worry less about their teen driver’s safety during the newly licensed phase, when crash risk is high as compared to the learning phase. Further research is needed into how to effectively

For some individuals, however, core beliefs may also explicitly involve spiritual themes. In this article, we propose a cognitive model of worry, in which positive/negative beliefs about the Divine affect symptoms through the mechanism of intolerance of uncertainty. Using mediation analyses, we found support for our model across two studies, in particular, with regards to negative spiritual beliefs. These findings highlight the importance of assessing for spiritual alongside secular convictions when creating cognitive-behavioral case formulations in the treatment of religious individuals. © 2011 Wiley Periodicals, Inc.

    The purpose of this study was to identify the effect of bus passengers' positions on their fear of danger when a bus stopped suddenly. A temporary bus running course with one bus stop was set up on the campus of the Tokyo University of Agriculture and Technology (TUAT). The bus ran the course 14 times with the bus stopping twice during the course, once at the bus stop and again just after re-starting from the bus stop. The driver was asked to brake more strongly than usual when stopping. Sixteen students (15 males and 1 female) between the ages of 18 and 21 years participated. In turn, all participants were asked to take 14 different postures in the bus. Participants were also asked to report their level of fear on a rating scale each time the bus stopped. The study showed that (1) passengers' fear of danger at the first sudden stop was typically higher than that at the second stop, (2) standing passengers who held hand straps experienced more fear than those who held fixed safety devices, (3) bus passengers sitting on the centre of the rear seat had a great risk of injury if the bus stopped suddenly, and (4) when passengers faced the window and stood transversely with respect to from the moving direction of the bus and the bus stopped suddenly, passengers' fear of danger was affected by the side of the bus on which they stood as well as which hand they used to grasp a safety device.

    The analysis of the presently available electroweak data including radiative corrections in the standard model suggests that the top quark weighs more than the Z 0 . We examine whether squark loops in the minimal supersymmetric model, particularly those involving stops (partners of the top quark), could reduce substantially the preferred range of top quark masses. Given the present lower bounds on squark masses, we find that stop effects can reduce the central value of m t by at most a few GeV, although they do make a very heavy top quark increasingly unlikely.

  1. Distinguishing obsessive features and worries: the role of thought-action fusion.

    Science.gov (United States)

    Coles, M E; Mennin, D S; Heimberg, R G

    2001-08-01

    Obsessions are a key feature of obsessive-compulsive disorder (OCD), and chronic worry is the cardinal feature of generalized anxiety disorder (GAD). However, these two cognitive processes are conceptually very similar, and there is a need to determine how they differ. Recent studies have attempted to identify cognitive processes that may be differentially related to obsessive features and worry. In the current study we proposed that (1) obsessive features and worry could be differentiated and that (2) a measure of the cognitive process thought-action fusion would distinguish between obsessive features and worry, being strongly related to obsessive features after controlling for the effects of worry. These hypotheses were supported in a sample of 173 undergraduate students. Thought-action fusion may be a valuable construct in differentiating between obsessive features and worry.

  2. Using residents' worries about technology as a way of resolving environmental remediation dilemmas.

    2017-02-15

    The choice of technologies used to remediate contaminated environments are increasingly made via engagement with affected local residents. Despite this, little is known about how residents perceive remediation technology applications. Building on the findings of broader technology worry research, and drawing on data from a telephone survey of 2009 residents living near thirteen contaminated sites in Australia, regression analysis of closed-ended survey questions and coding analysis of open-ended survey questions are combined to identify the main predictors of worries concerning particular remediation technologies, and how worry affects them. This suggests respondents are more worried about the application of chemical remediation technologies than the application of physical and thermal technologies, which in turn caused more worry than the application of biotechnology. The paper suggests that these worries can be reduced via direct engagement with residents about remediation technologies, suggesting that such engagement can provide knowledge that improves remediation technology decisions.

    Research has shown that Generalized Anxiety Disorder is one of the most common anxiety disorders found in adolescents today. Its main symptoms are disproportionate fear and anxiety (worrying) about work-related or school-related events or activities and social relations. Adolescents suffering from GAD symptoms have difficulty keeping fear and worries in check. This causes mounting stress and impairs their functioning. GAD sufferers tend to worry about issues stemming from social relationships...

  4. Nuclear stopping in transmission experiments

    International Nuclear Information System (INIS)

    Glazov, Lev G.; Sigmund, Peter

    2003-01-01

    Energy-loss spectra, mean and peak energy loss, and straggling due to elastic nuclear scattering have been studied theoretically as a function of target thickness and deflection angle of an initially monochromatic and well-collimated ion beam. The goal of this work has been to provide a generally valid scheme for nuclear-stopping corrections, allowing to determine electronic-stopping forces from energy-loss spectra measured in transmission geometry. Calculations have been based on the generalized Bothe-Landau theory of energy loss and multiple scattering. Our peak energy losses at zero emergence angle show close (∼10%) agreement with predictions of Fastrup et al. on the basis of the Bohr-Williams theory. However, predicted mean and peak energy losses are found to more sensitively depend on the underlying interatomic potential than unrestricted, i.e. angle-integrated mean or peak energy losses. Both elastic energy loss and multiple scattering are known to obey scaling laws involving only two combinations of the pertinent variables and atomic parameters. The dependence on deflection angle and foil thickness of mean and peak energy loss obeys a simple combination of these scaling laws. Comments are made on potential errors due to uncertainties in the nuclear-stopping correction applied in the literature with specific reference to central papers in low-velocity stopping

  5. Stop searches in flavourful supersymmetry

    Crivellin, Andreas; Tunstall, Lewis C.

    2016-01-01

    Natural realisations of supersymmetry require light stops ${\\tilde t}_1$, making them a prime target of LHC searches for physics beyond the Standard Model. Depending on the kinematic region, the main search channels are ${\\tilde t_1}\\to t \\tilde \\chi^0_1$, ${\\tilde t_1}\\to W b \\tilde \\chi^0_1$ and ${\\tilde t_1}\\to c \\tilde \\chi^0_1$. We first examine the interplay of these decay modes with ${\\tilde c_1}\\to c \\tilde \\chi^0_1$ in a model-independent fashion, revealing the existence of large regions in parameter space which are excluded for any ${\\tilde t_1}\\to c \\tilde \\chi^0_1$ branching ratio. This effect is then illustrated for scenarios with stop-scharm mixing in the right-handed sector, where it has previously been observed that the stop mass limits can be significantly weakened for large mixing. Our analysis shows that once the LHC bounds from ${\\tilde c_1}\\to c \\tilde \\chi^0_1$ searches are taken into account, non-zero stop-scharm mixing leads only to a modest increase in the allowed regions of parameter...

  6. Correlated ion stopping in plasmas

    International Nuclear Information System (INIS)

    Zwicknagel, G.; Deutsch, C.

    1997-01-01

    The basic features of correlated ion stopping in plasmas are demonstrated by employing two opposite extremes of cluster structures, a statistical model with a spatial ion distribution of Gaussian shape and the highly regular configuration of N-ion chains and cubic boxes. In the case of the ion chains the resonant character of correlated stopping due to the interference of the excited wake fields is discussed in detail. The general behavior of correlation effects is summarized and its dependence on the ratio of cluster size and interion spacing to the screening length in the plasma, as well as the ratio of the cluster velocity to the mean electron velocity in the target, is stressed out. The validity and applicability of the dielectric response formalism used for describing correlated stopping is critically reviewed. A scheme is presented to extend the linear formalism to weak nonlinear situations that occur, in particular, for small highly charged clusters at moderate or low velocities. For the Gaussian cluster a fit formula is given, which allows a fast and accurate calculation of the enhancement of stopping due to correlation effects and applies for all degrees of degeneracy of the electrons and arbitrary cluster velocities. copyright 1997 The American Physical Society

  13. Persisting roughness when deposition stops.

    Science.gov (United States)

    Schwartz, Moshe; Edwards, S F

    2004-12-01

    Useful theories for growth of surfaces under random deposition of material have been developed by several authors. The simplest theory is that introduced by Edwards and Wilkinson (EW), which is linear and soluble. Its nonlinear generalization by Kardar, Parisi, and Zhang (KPZ) resulted in many subsequent studies. Yet both EW and KPZ theories contain an unphysical feature. When deposition of material is stopped, both theories predict that as time tends to infinity, the surface becomes flat. In fact, of course, the final surface is not flat, but simply has no gradients larger than the gradient related to the angle of repose. We modify the EW and KPZ theories to accommodate this feature and study the consequences for the simpler system which is a modification of the EW equation. In spite of the fact that the equation describing the evolution of the surface is not linear, we find that the steady state in the presence of noise is not very different in the long-wavelength limit from that of the linear EW equation. The situation is quite different from that of EW when deposition stops. Initially there is still some rearrangement of the surface, but that stops as everywhere on the surface the gradient is less than that related to the angle of repose. The most interesting feature observed after deposition stops is the emergence of history-dependent steady-state distributions.

    We report some highlights of our work with heavy-ion stopping in the energy range where Bethe stopping theory breaks down. Main tools are our binary stopping theory (PASS code), the reciprocity principle, and Paul’s data base. Comparisons are made between PASS and three alternative theoretical schemes (CasP, HISTOP and SLPA). In addition to equilibrium stopping we discuss frozen-charge stopping, deviations from linear velocity dependence below the Bragg peak, application of the reciprocity principle in low-velocity stopping, modeling of equilibrium charges, and the significance of the so-called effective charge.

    2012-01-01

    A rocky re-start with beam followed a successful machine development period and the first technical stop of 2012. Today, Friday 11 May, the machine began running again with 1380 bunches.   A short, two-day machine development period was successfully completed on 21-22 April. It focused on topics relevant for the 2012 physics beam operation. This was then followed by a five-day technical stop, the first of the year. The technical stop finished on time on Friday 26 April. The re-start with beam was somewhat tortuous and hampered by an unlucky succession of technical faults leading to extended periods of downtime. The planned intensity increase was put on hold for three days with the machine operating with 1092 bunches and a moderate bunch intensity of 1.3x1011 protons. This delivered a reasonable peak luminosity of 3.6x1033 cm-2s-1 to ATLAS and CMS. Higher than usual beam losses were observed in the ramp and squeeze, and time was required to investigate the causes and to implement mitigati...

    To examine the association between worry and problem-solving skills and beliefs (confidence and perceived control) in primary school children. Children (8-11 years) were screened using the Penn State Worry Questionnaire for Children. High (N= 27) and low (N= 30) scorers completed measures of anxiety, problem-solving skills (generating alternative solutions to problems, planfulness, and effectiveness of solutions) and problem-solving beliefs (confidence and perceived control). High and low worry groups differed significantly on measures of anxiety and problem-solving beliefs (confidence and control) but not on problem-solving skills. Consistent with findings with adults, worry in children was associated with cognitive distortions, not skills deficits. Interventions for worried children may benefit from a focus on increasing positive problem-solving beliefs. ©2010 The British Psychological Society.

    2013-10-01

    The relationship between sleep and migraine headaches is complex. Changes in sleep patterns can trigger migraine attacks, and sleep disorders may be associated with increased migraine frequency. Furthermore, migraine patients and their doctors very consistently report that sleep relieves already established migraine attacks. Herein we will try to answer the question, "Why does sleep stop migraine?" Since evidence for this relationship is largely based on empirical clinical observation, we will not provide a clinical review of the association. Instead, we will focus on the pathophysiology of migraine attacks and its intersections with sleep biology.

    To examine the association between diet quality and feelings of worry, sadness or unhappiness in Canadian children. Responses to the Harvard Food Frequency Questionnaire of 6,528 grade 5 students were used to calculate a composite score of diet quality, and its components: variety, adequacy, moderation and balance. Responses to the question on "feelings of worry, sadness or unhappiness" from the EuroQoL 5 Dimension questions for Youth (EQ-5D-Y), a validated Health Related Quality of Life questionnaire, constitute the outcome of interest. Multilevel logistic regression methods were used to examine the association between diet quality and feelings of worry, sadness or unhappiness. All analyses were adjusted for gender, household income, parental education, energy intake, weight status, physical activity level, geographic area and year of data collection. Diet quality was inversely associated with children's feelings of worried, sad or unhappy (Odds ratio (95% confidence interval): 0.90 (0.85-0.97)). Dietary variety and dietary adequacy were also statistically significantly associated with lower odds of feeling worried, sad or unhappy. When the results were stratified by gender, the effect of diet on feeling worried, sad or unhappy was more pronounced in girls than boys. These findings suggest that diet quality plays a role in feelings of worry, sadness or unhappiness and complement other studies that have suggested the link between diet and mental health. We recommend consideration of diet quality in public health strategies that aim to reduce the burden of poor mental health in children and youth.

Worry in children is related to perceived parental rearing and attachment. Behavior Research and Therapy, 38, 487-497] regarding the relations between perceived parental rearing behaviors, self-reported attachment style, and worry in a community sample to a clinical sample of anxious children. Sixty-four children and adolescents, aged 7-18 years, with a primary anxiety disorder completed (a) the EMBU-C, a questionnaire measuring perceptions of parental rearing behaviors, (b) a single-item measure of attachment style, and (c) an index of worry severity. Findings revealed that child rated parental rearing behaviors, particularly parental rejection, were positively related to child worry. Self-reported attachment style was also related to worry, such that children who classified themselves as ambivalently attached reported higher levels of worry than did children who classified themselves as securely attached. Parenting style and attachment were found to make independent contributions to worry. The results are compared to those from Muris et al.'s community study, and implications for future research are discussed.

    2000-05-01

    In a sample of 159 primary school children, the relationship between perceived parental rearing behaviours and self-reported attachment style, on the one hand, and worry, on the other hand, was investigated. Children completed (a) the EMBU, a questionnaire measuring perceptions of parental rearing behaviours, (b) a single-item measure of attachment style, and (c) the Penn State Worry Questionnaire for Children (PSWQ-C), an index of severity of worrying. Results showed that parental rearing behaviours, in particular rejection and anxious rearing, were positively associated with worry. Thus, children who perceived their parents as more rejective and anxious reported higher levels of worry. Furthermore, self-reported attachment style appeared to be related to worry. More specifically, children who classified themselves as avoidantly or ambivalently attached displayed higher levels of worry than did children who classified themselves as securely attached. These findings are consistent with the notion that family environment factors such as parental rearing and attachment style contribute to the severity of anxiety symptoms in children.

    Sixty-one high-math-anxious persons and sixty-one low-math-anxious persons completed a modified working memory capacity task, designed to measure working memory capacity under a dysfunctional math-related context and working memory capacity under a valence-neutral context. Participants were required to perform simple tasks with emotionally benign material (i.e., lists of letters) over short intervals while simultaneously reading and making judgments about sentences describing dysfunctional math-related thoughts or sentences describing emotionally-neutral facts about the world. Working memory capacity for letters under the dysfunctional math-related context, relative to working memory capacity performance under the valence-neutral context, was poorer overall in the high-math-anxious group compared with the low-math-anxious group. The findings show a particular difficulty employing working memory in math-related contexts in high-math-anxious participants. Theories that can provide reasonable interpretations for these findings and interventions that can reduce anxiety-induced worrying intrusive thoughts or improve working memory capacity for math anxiety are discussed.

  15. Optimal Stopping with Information Constraint

    2012-01-01

    We study the optimal stopping problem proposed by Dupuis and Wang (Adv. Appl. Probab. 34:141–157, 2002). In this maximization problem of the expected present value of the exercise payoff, the underlying dynamics follow a linear diffusion. The decision maker is not allowed to stop at any time she chooses but rather on the jump times of an independent Poisson process. Dupuis and Wang (Adv. Appl. Probab. 34:141–157, 2002), solve this problem in the case where the underlying is a geometric Brownian motion and the payoff function is of American call option type. In the current study, we propose a mild set of conditions (covering the setup of Dupuis and Wang in Adv. Appl. Probab. 34:141–157, 2002) on both the underlying and the payoff and build and use a Markovian apparatus based on the Bellman principle of optimality to solve the problem under these conditions. We also discuss the interpretation of this model as optimal timing of an irreversible investment decision under an exogenous information constraint.

    Generalized anxiety disorder (GAD) is the most commonly occurring anxiety disorder and has been related to cardiovascular morbidity such as cardiac ischemia, sudden cardiac death, and myocardial infarction. Both GAD and its cardinal symptom - worry - have been shown to promote muted physiological reactivity in response to laboratory and ecological stressors. Importantly, no study to date has examined the concurrent and relative contributions of trait and state worry within healthy controls, (non-clinical) high trait-worry controls, and GAD participants. The present study examined heart rate (HR), respiratory sinus arrhythmia (RSA), and salivary alpha-amylase (sAA) responses to laboratory stress during and following the experimental induction of worry versus relaxation in healthy controls (n=42), high trait worriers (n=33) and participants with GAD (n=76). All groups exhibited increased HR and decreased RSA in response to the stressor, with no differences by condition. Baseline sAA significantly moderated HR and RSA reactivity, such that higher sAA predicted greater increases in HR and decreases in RSA. There was a significant group by baseline sAA interaction such that in GAD, higher baseline sAA predicted decreased change in sAA during stress, whereas higher baseline sAA predicted greater sAA change in healthy controls. High-worry controls fell non-significantly between these groups. The present study provides additional evidence for the effect of worry on diminished HR stress response and points to possible suppression of adrenergic sympathetic stress responses in GAD.

    Full Text Available Recent studies on the Zarit Burden Interview (ZBI support the existence of a unique factor, worry about caregiving performance (WaP, beyond role and personal strain. Our current study aims to confirm the existence of WaP within the multidimensionality of ZBI and to determine if predictors of WaP differ from the role and personal strain. We performed confirmatory factor analysis (CFA on 466 caregiver-patient dyads to compare between one-factor (total score, two-factor (role/personal strain, three-factor (role/personal strain and WaP, and four-factor models (role strain split into two factors. We conducted linear regression analyses to explore the relationships between different ZBI factors with socio-demographic and disease characteristics, and investigated the stage-dependent differences between WaP with role and personal strain by dyadic relationship. The four-factor structure that incorporated WaP and split role strain into two factors yielded the best fit. Linear regression analyses reveal that different variables significantly predict WaP (adult child caregiver and Neuropsychiatric Inventory Questionnaire (NPI-Q severity from role/personal strain (adult child caregiver, instrumental activities of daily living, and NPI-Q distress. Unlike other factors, WaP was significantly endorsed in early cognitive impairment. Among spouses, WaP remained low across Clinical Dementia Rating (CDR stages until a sharp rise in CDR 3; adult child and sibling caregivers experience a gradual rise throughout the stages. Our results affirm the existence of WaP as a unique factor. Future research should explore the potential of WaP as a possible intervention target to improve self-efficacy in the milder stages of burden.

  2. Optimally stopped variational quantum algorithms

    2018-04-01

    Quantum processors promise a paradigm shift in high-performance computing which needs to be assessed by accurate benchmarking measures. In this article, we introduce a benchmark for the variational quantum algorithm (VQA), recently proposed as a heuristic algorithm for small-scale quantum processors. In VQA, a classical optimization algorithm guides the processor's quantum dynamics to yield the best solution for a given problem. A complete assessment of the scalability and competitiveness of VQA should take into account both the quality and the time of dynamics optimization. The method of optimal stopping, employed here, provides such an assessment by explicitly including time as a cost factor. Here, we showcase this measure for benchmarking VQA as a solver for some quadratic unconstrained binary optimization. Moreover, we show that a better choice for the cost function of the classical routine can significantly improve the performance of the VQA algorithm and even improve its scaling properties.

  3. How to stop global warming

    This paper reports on how to stop global warming. At the Toronto Conference on Climate Change in 1988, the world's industrialized nations agreed on a goal of cutting greenhouse gas emissions 20 percent by the year 2005. This would not stabilize atmospheric levels of greenhouse gases but would at least slow their accumulation. Although difficult to achieve, the Toronto goal is certainly reachable. Newer, more efficient technologies can lower energy consumption without effecting economic output. CFC- substitutes can provide refrigeration. In fact, an international carbon tax of just $1 per barrel of oil, or $6 per ton of coal, would generate more than enough revenue to pay for the necessary fuel-saving measures. This tax could result from an international agreement similar to the 1987 Montreal Protocol, which obliges its signatories to cut down on production of CFCs

  4. Emotion as a boost to metacognition: how worry enhances the quality of confidence.

    2014-10-01

    Emotion and cognition are known to interact during human decision processes. In this study we focus on a specific kind of cognition, namely metacognition. Our experiment induces a negative emotion, worry, during a perceptual task. In a numerosity task subjects have to make a two alternative forced choice and then reveal their confidence in this decision. We measure metacognition in terms of discrimination and calibration abilities. Our results show that metacognition, but not choice, is affected by the level of worry anticipated before the decision. Under worry individuals tend to have better metacognition in terms of the two measures. Furthermore understanding the formation of confidence is better explained with taking into account the level of worry in the model. This study shows the importance of an emotional component in the formation and the quality of the subjective probabilities. Copyright © 2014 Elsevier Inc. All rights reserved.

    Meta-cognitive beliefs associated with pathological worry and generalized anxiety disorder (GAD) may encompass the likelihood subtype of thought-action fusion (TAF), the belief that one's thoughts can influence outside events. In the current study of 494 undergraduate college students, positive correlations between scores on the Penn State Worry Questionnaire (PSWQ) and the two Likelihood subscales of the TAF Scale were found, and participants endorsing at least some DSM-IV diagnostic criteria for GAD scored significantly higher on both TAF-Likelihood subscales than participants reporting no GAD symptoms. However, these TAF scales did not predict GAD diagnostic status with PSWQ included as a predictor. In contrast to previous research, the TAF-Moral scale did not correlate with worry. Relationships between TAF, pathological worry, and meta-cognition are discussed in relation to GAD.

  6. Neurasthenia, Generalized Anxiety Disorder, and the Medicalization of Worry in a Vietnamese Psychiatric Hospital.

    Tran, Allen L

    2017-06-01

    This article examines two forms of the medicalization of worry in an outpatient psychiatric clinic in Ho Chi Minh City, Vietnam. Biomedical psychiatrists understand patients' symptoms as manifestations of the excessive worry associated with generalized anxiety disorder (GAD). Drawing on an ethnopsychology of emotion that reflects increasingly popular models of neoliberal selfhood, these psychiatrists encourage patients to frame psychic distress in terms of private feelings to address the conditions in their lives that lead to chronic anxiety. However, most patients attribute their symptoms to neurasthenia instead of GAD. Differences between doctors' and patients' explanatory models are not just rooted in their understandings of illness but also in their respective conceptualizations of worry in terms of emotion and sentiment. Patients with neurasthenia reject doctors' attempts to psychologize distress and maintain a model of worry that supports a sense of moral selfhood based on notions of obligation and sacrifice. © 2016 by the American Anthropological Association.

    Intolerance of uncertainty (IU) can be defined as a cognitive bias that affects how a person perceives, interprets, and responds to uncertain situations. Although IU has been reported mainly in literature relating to worry and anxiety symptoms, it may be also important to investigate the relationship between IU, rumination, and depression in a clinical sample. Furthermore, individuals who are intolerant of uncertainty easily experience stress and could cope with stressful situations using repetitive thought such as worry and rumination. Thus, we investigated whether different forms of repetitive thought differentially mediate the relationship between IU and psychological symptoms. Participants included 27 patients with MDD, 28 patients with GAD, and 16 patients with comorbid GAD/MDD. Even though worry, rumination, IU, anxiety, and depressive symptoms correlated substantially with each other, worry partially mediated the relationship between IU and anxiety whereas rumination completely mediated the relationship between IU and depressive symptoms.

    The aim of this study was to determine the issues patients worry about when making decisions about cancer treatment. A total of 5,044 colorectal and lung cancer patients from the Cancer Care Outcomes Research and Surveillance Consortium reported their level of worry about (1) treatment side effects, (2) treatment costs, (3) time away from family, (4) time away from work, and (5) transportation to treatment sites. Using multivariable logistic regression, we evaluated the association of sociodemographic, clinical, and psychosocial variables with worry. Overall, 75 % of patients worried about side effects of treatments; 40 %, the cost of treatment; 50 %, time away from family; 52 %, time away from work; and 22 %, about transportation. In multivariable analyses, across all worry domains, older patients had lower odds of reporting worry (p values perceived less than excellent quality of care, self-assessed their health as less than excellent, and those with a higher cancer stage were more likely to report worry. Asian patients were more likely to report worry than Whites about the cost of treatment and transportation, and relative to Whites, Hispanics were more likely to report worry about transportation (p values ethnicity. Understanding the source of patient worry and identifying interventions to alleviate worry are important to delivering patient-centered cancer care.

  9. Worry amplifies theory-of-mind reasoning for negatively valenced social stimuli in generalized anxiety disorder.

    Zainal, Nur Hani; Newman, Michelle G

    2018-02-01

    Theory-of-mind (ToM) is the ability to accurately infer others' thoughts and feelings. In generalized anxiety disorder (GAD), cognitive and emotion regulation theories allude to the plausibility that ToM is conditional on the degree of individuals' state worry, a hallmark symptom. GAD and state worry may interact to predict ToM constructs. However, no experiments have directly tested such interactional hypotheses, and used ToM as a framework to advance understanding of social cognition in GAD. This study therefore aimed to address this gap. 171 participants (69 GAD, 102 Controls) were randomly assigned to either a Worry or Relaxation induction and completed well-validated ToM decoding (Reading the Mind in the Eyes Test) and reasoning (Movie for the Assessment of Social Cognition) tasks. GAD status significantly interacted with state worry to predict accuracy of overall reasoning, cognitive-reasoning, positive-reasoning, and negative-reasoning ToM. Worry, as opposed to relaxation, led sufferers of GAD to display more accurate overall reasoning and cognitive-reasoning ToM than controls, especially for negative signals. Participants with GAD who worried, but not relaxed, were also significantly better than the norm at interpreting negative signals. These findings remained after controlling for gender, executive function, social anxiety, and depressive symptoms. For other ToM abilities, mean scores of persons with and without GAD who either worried or relaxed were normative. The ToM reasoning measure lacked self-reference, and these preliminary findings warrant replication. Theoretical implications, such as the state worry-contingent nature of ToM in GAD, and clinical implications are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

  10. When we should worry more: using cognitive bias modification to drive adaptive health behaviour.

    A lack of behavioural engagement in health promotion or disease prevention is a problem across many health domains. In these cases where people face a genuine danger, a reduced focus on threat and low levels of anxiety or worry are maladaptive in terms of promoting protection or prevention behaviour. Therefore, it is possible that increasing the processing of threat will increase worry and thereby enhance engagement in adaptive behaviour. Laboratory studies have shown that cognitive bias modification (CBM) can increase or decrease anxiety and worry when increased versus decreased processing of threat is encouraged. In the current study, CBM for interpretation (CBM-I) is used to target engagement in sun protection behaviour. The goal was to investigate whether inducing a negative rather than a positive interpretation bias for physical threat information can enhance worry elicited when viewing a health campaign video (warning against melanoma skin cancer), and consequently lead to more adaptive behaviour (sun protection). Participants were successfully trained to either adopt a positive or negative interpretation bias using physical threat scenarios. However, contrary to expectations results showed that participants in the positive training condition reported higher levels of worry elicited by the melanoma video than participants in the negative training condition. Video elicited worry was, however, positively correlated with a measure of engagement in sun protection behaviour, suggesting that higher levels of worry do promote adaptive behaviour. These findings imply that more research is needed to determine under which conditions increased versus decreased processing of threat can drive adaptive worry. Various potential explanations for the current findings and suggestions for future research are discussed.

  14. Measurement of stopping power of heavy ions

    International Nuclear Information System (INIS)

    Kitahara, Tetsuo

    1981-01-01

    The stopping power of heavy ions is discussed. In the low energy region, heavy ions keep some of their orbital electrons, and have equilibrium electron charge. The stopping power of penetrating particles depends on this effective charge. At present, it is hard to estimate this effective charge theoretically, accordingly, the estimation is made experimentally. Another difficulty in this estimation is that the Born approximation is not effective for heavy ions. In the low energy region, electronic stopping and nuclear stopping contribute to the stopping power. For the electronic stopping, a formula for the stopping power was given by Lindhard et al. The experimental values were obtained at GSI, and are inconsistent with the estimation by the Lindhard's formula. In the high energy region, where the Born approximation can be used, the Bethe's formula is applied, but the experimental data are scarce. Oscillations are seen in the Z dependence graph of the experimental stopping cross sections. Experimental works on the stopping power have been done. The differential and the integral methods were carried out. (Kato, T.)

  15. Electrocortical consequences of image processing: The influence of working memory load and worry.

    White, Evan J; Grant, DeMond M

    2017-03-30

    Research suggests that worry precludes emotional processing as well as biases attentional processes. Although there is burgeoning evidence for the relationship between executive functioning and worry, more research in this area is needed. A recent theory suggests one mechanism for the negative effects of worry on neural indicators of attention may be working memory load, however few studies have examined this directly. The goal of the current study was to document the influence of both visual and verbal working memory load and worry on attention allocation during processing of emotional images in a cued image paradigm. It was hypothesized that working memory load will decrease attention allocation during processing of emotional images. This was tested among 38 participants using a modified S1-S2 paradigm. Results indicated that both the visual and verbal working memory tasks resulted in a reduction of attention allocation to the processing of images across stimulus types compared to the baseline task, although only for individuals low in worry. These data extend the literature by documenting decreased neural responding (i.e., LPP amplitude) to imagery both the visual and verbal working memory load, particularly among individuals low in worry.

    Full Text Available Abstract Worrying is the central feature of generalized anxiety disorder (GAD. Many people worry from time to time, but in GAD the worrying is prolonged and difficult to control. Worrying is a specific way of coping with perceived threats and feared situations. Meanwhile, it is not considered to be a helpful coping strategy, and the phenomenological account developed in this paper aims to show why. It builds on several phenomenological notions and in particular on Michael Wheeler's application of these notions to artificial intelligence and the cognitive sciences. Wheeler emphasizes the value of 'online intelligence' as contrasted to 'offline intelligence'.

    The aim of this study is to investigate prevalence of irritable bowel syndrome (IBS) among adolescents and difference in worry and stress between normal and IBS groups. Questionnaire survey was conducted at a girl's middle and high school. Students from seventh to eleventh grade participated in the examination on Rome II criteria, lifestyle and dietary habits. Worry and stress were measured with the Korean version Penn State Worry Questionnaire-Children and the Korean version Brief Encounter Psychosocial Instrument. Worry score was significantly higher in the IBS group (22.07 ± 9.38, P high school students than in middle school students (P = 0.02). Stress score also was higher in the IBS group than in the normal group (P high school girls than in the middle school ones (P = 0.04). Of all the lifestyle factors influencing IBS preference for fatty foods, preference for salty foods, drinking alcohol and sleeping for less than six hours a day were found to be significant. Worry and stress seem to be associated with IBS symptoms. The findings of this study draw a clue that less worry and stress will help decrease IBS symptoms.

    Full Text Available Disease-related worries are frequently reported in inflammatory bowel disease (IBD, but longitudinal assessments of these worries are scarce. In the present study, patients completed the rating form of IBD patient concerns (RFIPC at three occasions during one year. One-way analysis of variance (ANO VA, t-tests, bivariate correlation, and linear regression analyses were used to analyse data. The validity and reliability of the Norwegian RFIPC was tested. A total of 140 patients were included (V1, ulcerative colitis (UC n = 92, Crohn's disease (CD n = 48, mean age 46.9 and 40.0-year old, respectively. The highest rated worries included having an ostomy bag, loss of bowel control, and reduced energy levels. Symptoms were positively associated with more worries. A pattern of IBD-related worries was consistent over a period of one year. Worries about undergoing surgery or having an ostomy bag seemed to persist even when symptoms improved. The Norwegian RFIPC is valid and reliable.

    To test the hypothesize that increased heart rate (HR) and decreased heart rate variability (HRV) are not only due to concurrent stressful events and worries but also to stressors and worries occurring in the preceding hours or stressors anticipated to occur in the next hour. Worry was expected to mediate at least part of the prolonged effects of stressors. Ambulatory HR and HRV of 73 teachers were recorded for 4 days, during which the participants reported occurrence and duration of worry episodes and stressful events on an hourly basis, using computerized diaries. Multilevel regression models were used, accounting for effects of several biobehavioral variables. Stressful events were not associated with changes in HR or HRV. However, worry episodes had effects on concurrent HR and HRV (2.55 beats/minute; -5.76 milliseconds) and HR and HRV in the succeeding hour (3.05 beats/minute; -5.80 milliseconds) and 2 hours later (1.52 beats/minute; -3.14 milliseconds). These findings were independent of emotions, physical activity, posture, and other biobehavioral factors. Worry has effects on cardiac activity, and these effects were still visible after 2 hours. The latter finding suggests that a considerable part of prolonged activation may be induced by unconscious stress-related cognition.

  1. Respiratory sinus arrhythmia during worry forecasts stress-related increases in psychological distress.

    2014-09-01

    Respiratory sinus arrhythmia (RSA) has been conceptualized as an index of emotion regulation abilities. Although resting RSA has been associated with both concurrent and prospective affective responses to stress, the impact of RSA reactivity on emotional responses to stress is inconsistent across studies. The type of emotional stimuli used to elicit these phasic RSA responses may influence the adaptive value of RSA reactivity. We propose that RSA reactivity to a personally relevant worry-based stressor might forecast future affective responses to stress. To evaluate whether resting RSA and RSA reactivity to worry inductions predict stress-related increases in psychological distress, an academic stress model was used to prospectively examine changes in psychological distress from the well-defined low- and high-stress periods. During the low-stress period, 76 participants completed self-report mood measures and had their RSA assessed during a resting baseline, free worry period and worry catastrophizing interview. Participants completed another mood assessment during the high-stress period. Results indicated that baseline psychological distress predicted larger decreases in RSA during the worry inductions. Lower resting RSA and greater RSA suppression to the worry inductions at baseline prospectively predicted larger increases in psychological distress from the low- to high-stress period, even after accounting for the impact of baseline distress on RSA. These results provide further evidence that RSA may represent a unique index of emotion regulation abilities in times of stress.

    To investigate whether worries about work are linked to people's own cortisol levels and their spouses' cortisol levels in everyday life and whether marital factors may moderate these links. Although research has shown that satisfying marriages can buffer the physiological effects of everyday stress, the specific mechanisms through which marriage influences the processing and transmission of stress have not yet been identified. Thirty-seven healthy married couples completed baseline measures and then provided saliva samples and indicated their worries about work for six times a day from a Saturday morning through a Monday evening. Wives' cortisol levels were associated positively with their own work worries (p = .008) and with their husbands' work worries (p = .006). Husbands' cortisol levels were associated positively only with their own work worries (p = .015). Wives low in both marital satisfaction and disclosure showed a stronger association between work worries and cortisol compared with wives reporting either high marital satisfaction and/or high marital disclosure. These results suggest that momentary feelings of stress affect not only one's own cortisol levels but affect close others' cortisol levels as well. Furthermore, they suggest that, for women, the stress-buffering effects of a happy marriage may be partially explained by the extent to which they disclose their thoughts and feelings with their spouses.

  9. Slow, stopped and stored light

    2005-01-01

    Light that can been slowed to walking pace could have applications in telecommunications, optical storage and quantum computing. Whether we use it to estimate how far away a thunderstorm is, or simply take it for granted that we can have a conversation with someone on the other side of the world, we all know that light travels extremely fast. Indeed, special relativity teaches us that nothing in the universe can ever move faster than the speed of light in a vacuum: 299 792 458 ms sup - sup 1. However, there is no such limitation on how slowly light can travel. For the last few years, researchers have been routinely slowing light to just a few metres per second, and have recently even stopped it dead in its tracks so that it can be stored for future use. Slow-light has considerable popular appeal, deriving perhaps from the importance of the speed of light in relativity and cosmology. If everyday objects such as cars or people can travel faster than 'slow' light, for example, then it might appear that relativistic effects could be observed at very low speeds. Although this is not the case, slow light nonetheless promises to play an important role in optical technology because it allows light to be delayed for any period of time desired. This could lead to all-optical routers that would increase the bandwidth of the Internet, and applications in optical data storage, quantum information and even radar. (U.K.)

  10. Stopping atoms with diode lasers

    The use of light pressure to cool and stop neutral atoms has been an area of considerable interest recently. Cooled neutral atoms are needed for a variety of interesting experiments involving neutral atom traps and ultrahigh-resolution spectroscopy. Laser cooling of sodium has previously been demonstrated using elegant but quite elaborate apparatus. These techniques employed stabilized dye lasers and a variety of additional sophisticated hardware. The authors have demonstrated that a frequency chirp technique can be implemented using inexpensive diode lasers and simple electronics. In this technique the atoms in an atomic beam scatter resonant photons from a counterpropagating laser beam. The momentum transfer from the photons slows the atoms. The primary difficulty is that as the atoms slow their Doppler shift changes, and so they are no longer in resonance with the incident photons. In the frequency chirp technique this is solved by rapidly changing the laser frequency so that the atoms remain in resonance. To achieve the necessary frequency sweep with a dye laser one must use an extremely sophisticated high-speed electrooptic modulator. With a diode laser, however, the frequency can be smoothly and rapidly varied over many gigahertz simply by changing the injection current

  13. Perceptual assessment of fricative--stop coarticulation.

    The perceptual dependence of stop consonants on preceding fricatives [Mann and Repp, J. Acoust. Soc. Am. 69, 548--558 (1981)] was further investigated in two experiments employing both natural and synthetic speech. These experiments consistently replicated our original finding that listeners, report velar stops following [s]. In addition, our data confirmed earlier reports that natural fricative noises (excerpted from utterances of [st alpha], [sk alpha], [(formula: see text)k alpha]) contain cues to the following stop consonants; this was revealed in subjects' identifications of stops from isolated fricative noises and from stimuli consisting of these noises followed by synthetic CV portions drawn from a [t alpha]--[k alpha] continuum. However, these cues in the noise portion could not account for the contextual effect of fricative identity ([formula: see text] versus [sp) on stop perception (more "k" responses following [s]). Rather, this effect seems to be related to a coarticulatory influence of a preceding fricative on stop production; Subjects' responses to excised natural CV portions (with bursts and aspiration removed) were biased towards a relatively more forward place of stop articulation when the CVs had originally been preceded by [s]; and the identification of a preceding ambiguous fricative was biased in the direction of the original fricative context in which a given CV portion had been produced. These findings support an articulatory explanation for the effect of preceding fricatives on stop consonant perception.

  1. Intolerance of Uncertainty, anxiety, and worry in children and adolescents: A meta-analysis.

    Science.gov (United States)

    Osmanağaoğlu, Nihan; Creswell, Cathy; Dodd, Helen F

    2018-01-01

    Intolerance of uncertainty (IU) has been implicated in the development and maintenance of worry and anxiety in adults and there is an increasing interest in the role that IU may play in anxiety and worry in children and adolescents. We conducted a systematic review and meta-analysis to summarize existing research on IU with regard to anxiety and worry in young people, and to provide a context for considering future directions in this area of research. The systematic review yielded 31 studies that investigated the association of IU with either anxiety or worry in children and adolescents. The meta-analysis showed that IU accounted for 36.00% of the variance in anxiety and 39.69% in worry. Due to the low number of studies and methodological factors, examination of potential moderators was limited; and of those we were able to examine, none were significant moderators of either association. Most studies relied on questionnaire measures of IU, anxiety, and worry; all studies except one were cross-sectional and the majority of the studies were with community samples. The inclusion of eligible studies was limited to studies published in English that focus on typically developing children. There is a strong association between IU and both anxiety and worry in young people therefore IU may be a relevant construct to target in treatment. To extend the existing literature, future research should incorporate longitudinal and experimental designs, and include samples of young people who have a range of anxiety disorders.

  10. How to Stop Disagreeing and Start Cooperatingin the Presence of Asymmetric Packet Loss.

    Morales-Ponce, Oscar; Schiller, Elad M; Falcone, Paolo

    2018-04-22

    We consider the design of a disagreement correction protocol in multi-vehicle systems. Vehicles broadcast in real-time vital information such as position, direction, speed, acceleration, intention, etc. This information is then used to identify the risks and adapt their trajectory to maintain the highest performance without compromising the safety. To minimize the risk due to the use of inconsistent information, all cooperating vehicles must agree whether to use the exchanged information to operate in a cooperative mode or use the only local information to operate in an autonomous mode. However, since wireless communications are prone to failures, it is impossible to deterministically reach an agreement. Therefore, any protocol will exhibit necessary disagreement periods. In this paper, we investigate whether vehicles can still cooperate despite communication failures even in the scenario where communication is suddenly not available. We present a deterministic protocol that allows all participants to either operate a cooperative mode when vehicles can exchange all the information in a timely manner or operate in autonomous mode when messages are lost. We show formally that the disagreement time is bounded by the time that the communication channel requires to deliver messages and validate our protocol using NS-3 simulations. We explain how the proposed solution can be used in vehicular platooning to attain high performance and still guarantee high safety standards despite communication failures.

  11. Benefits of a Single-Person Spacecraft for Weightless Operations. [(Stop Walking and Start Flying)

    Griffin, Brand N.

    2012-01-01

    Historically, less than 20 percent of crew time related to extravehicular activity (EVA) is spent on productive external work.1 A single-person spacecraft with 90 percent efficiency provides productive new capabilities for maintaining the International Space Station (ISS), exploring asteroids, and servicing telescopes or satellites. With suits, going outside to inspect, service or repair a spacecraft is time-consuming, requiring pre-breathe time, donning a fitted space suit, and pumping down an airlock. For ISS, this is between 12.5 and 16 hours for each EVA, not including translation and work-site set up. The work is physically demanding requiring a day of rest between EVAs and often results in suit-induced trauma with frequent injury to astronauts fingers2. For maximum mobility, suits use a low pressure, pure oxygen atmosphere. This represents a fire hazard and requires pre-breathing to reduce the risk of decompression sickness (bends). With virtually no gravity, humans exploring asteroids cannot use legs for walking. The Manned Maneuvering Unit offers a propulsive alternative however it is no longer in NASA s flight inventory. FlexCraft is a single person spacecraft operating at the same cabin atmosphere as its host so there is no risk of the bends and no pre-breathing. This allows rapid, any-time access to space for repeated short or long EVAs by different astronauts. Integrated propulsion eliminates hand-over-hand translation or having another crew member operate the robotic arm. The one-size-fits-all FlexCraft interior eliminates the suit part inventory and crew time required to fit all astronauts. With a shirtsleeve cockpit, conventional displays and controls are used and because the work is not strenuous no rest days are required. Furthermore, there is no need for hand tools because manipulators are equipped with force multiplying end-effectors that can deliver the precise torque for the job.

  13. Starting from grape cultivation.

    Yoshida, A

    1992-06-01

    Rapid population growth can only be stopped by lowering the fertility rate. The UNFPA recommends improving the employment opportunities for women as the single best way of achieving this reduction. An example of this phenomenon is the grape cultivation in the Nordeste (Northeastern) region of Brazil. This area is the poorest part of Brazil and has the highest proportion of indigent people. These people have been deforesting the Amazon in search of a better life. What they have done is sterilize the land and turned a tropical rain forest into a desert. In an effort to reverse this trend, grape cultivation has been introduced in an area called Petrolina. The area is very dry with less than 500 mm of precipitation annually. They do have access to a 5000 square kilometer artificial lake (the largest in the world) and the 3rd largest river in Brazil (the Sao Francisco). In an effort to avoid using agricultural medicines, the vines are fertilized with organic matter created on the farm and little or no pesticides are used since pests do not live in such an arid region. It has taken 20 years of trial and error, but the quality of the grapes is now very high and is competitive on the world market. Because of climate and location, harvesting is done year round which increases the productivity of the land. The farm managers have found that married women make the best workers and have the highest level of productivity. Age at 1st marriage averages 24-25, compared with 15-16 for unemployed women in the same area. The fertility rate averages 50% of that for unemployed women in the same area. Agricultural development offers the best opportunity for the women of developing countries. It can pay a high wage, reduce fertility, and replant desert areas.

    2004-12-01

    This study assessed quality of life, self-esteem and worries in young adult survivors of childhood cancer compared to a group of young adults with no history of cancer. The impact of demographic, medical and treatment factors and self-esteem on survivors' quality of life and worries was studied. Participants were 400 long-term survivors (LTS) of childhood cancer (age range 16-49 years, 45% female) who had completed treatment an average of 16 years previously and 560 persons (age range 16-53 years, 55% female) with no history of cancer. All participants completed the MOS-24 (Medical Outcome Study Scale), a Worry questionnaire consisting of three scales (cancer-specific concerns, general health concerns, present and future concerns), and the Rosenberg Self-Esteem Scale. Small to moderate differences were found in mean MOS-24 scores between the LTS group and controls (range effect sizes -0.36-0.22). No significant difference was found in the mean self-esteem scores between LTS and controls. Female LTS had more cancer-specific concerns than male LTS. In several related areas of general health, self-image and dying, the LTS group reported less worries than controls, but LTS worried significantly more about their fertility, getting/changing a job and obtaining insurance's. Multiple linear regression analysis revealed that female gender, unemployment, severe late effects/health problems and a low self-esteem were predictors of worse quality of life in survivors. In addition, age at follow-up, unemployment, years since completion of therapy and a low self-esteem were associated with a higher degree of survivors' worries. Quality of life and the level of self-esteem in LTS of childhood cancer is not different from their peers. Although many LTS worried not more or even less about health issues than their peers, they often are concerned about some present and future concerns. The investigated factors could explain poor quality of life and worries only to a limited extent

    Berenbaum, Howard; Okazaki, Sumie

    2012-01-01

    The current study examined perceptions of living up to parental expectations and personal standards as possible mediators of the relationship between ethnicity and worry in a sample of 836 Asian American and 856 White American college students. Asian Americans reported higher frequency of academic- and family-related worry, but they did not report higher levels of global tendency to worry. Perceptions of living up to parental expectations of current academic performance and personal standards for preparation for a future career partially explained ethnic differences in frequency of academic worry. Personal standards and perceptions of living up to parental expectations for respect for the family partially explained ethnic differences in frequency of family worry. The findings highlight the importance of targeting domain-specific personal standards and perceived parental expectations to reduce worry among Asian Americans. PMID:22416875

    van der Molen, Juliette H Walma; Bushman, Brad J

    2008-09-01

    To examine whether violence in fictional and news television content frightens and worries children. Mixed factorial. Type of reaction (fright, worry) and television programming (violent news, violent fiction) were within-subjects factors, whereas age, sex, and television viewing frequency were between-subjects factors. Participants included 572 children (47% boys), aged 8 to 12 years, from 9 urban and rural primary schools in the Netherlands. The main exposure was to descriptions of 8 threats frequently depicted in fictional and news programs (eg, murder, war, house fires). Children reported whether they were frightened or worried by these threats. Violent threats increased both fright and worry. These 2 reactions could be distinguished from one another in a factor analysis. When violent content was described as news, it produced more fear reactions than when it was described as fiction. Fright and worry were greater in girls than in boys, in younger children than in older children, and in light television viewers than in heavy television viewers. Pediatricians should inform parents, educators, policy makers, and broadcasters about the potentially harmful effect of violent programming on children's emotions, especially in the case of news programming.

  1. Health worry, physical activity participation, and walking difficulty among older adults: a mediation analysis.

    Li, Kin-Kit; Cardinal, Bradley J; Vuchinich, Samuel

    2009-03-01

    This study examined the effect of health worry (i.e., cognitive aspect of anxiety resulting from concern for health) on walking difficulty in a nationally representative sample (N = 7,527) of older adults (M age = 76.83 years). The study further tested whether physical activity mediates the effect of health worry on walking difficulty in a 6-year follow-up design. Results of a mediation analysis using structural equation modeling showed that people with a high degree of health worry engaged in less physical activity (beta = -.24, p < .001), and people who participated in less physical activity were more likely to report walking difficulty at the 6-year follow-up (beta = -.22, p < .001). There was a significant indirect effect from health worry to walking difficulty through physical activity (beta = .05, p < .001), controlling for demographic, psychosocial, and health related factors. Results suggested that inducing threat and worry may not be effective for physical activity promotion in the older population. More promising coping and regulation strategies are discussed.

    Fogel, Joshua; Chawla, Gurasees S

    Risk perception and psychological concerns are relevant for understanding how people view Lyme disease. This study investigates the four separate outcomes of susceptibility, likelihood to be diagnosed, worry, and fear for contracting Lyme disease. University students (n=713) were surveyed about demographics, perceived health, Lyme disease knowledge, Lyme disease preventive behaviors, Lyme disease history, and Lyme disease miscellaneous variables. We found that women were associated with increased susceptibility and fear. Asian/Asian-American race/ethnicity was associated with increased worry and fear. Perceived good health was associated with increased likelihood to be diagnosed, worry, and fear. Correct knowledge was associated with increased susceptibility and likelihood to be diagnosed. Those who typically spend a lot of time outdoors were associated with increased susceptibility, likelihood to be diagnosed, worry, and fear. In conclusion, healthcare providers and public health campaigns should address susceptibility, likelihood to be diagnosed, worry, and fear about Lyme disease, and should particularly target women and Asians/Asian-Americans to address any possible misconceptions and/or offer effective coping strategies.

  3. Stopping of hypervelocity clusters in solids

    International Nuclear Information System (INIS)

    Anders, Christian; Ziegenhain, Gerolf; Urbassek, Herbert M; Bringa, Eduardo M

    2011-01-01

    Using molecular-dynamics simulations, we study the processes underlying the stopping of energetic clusters upon impact in matter. We investigate self-bombardment of both a metallic (Cu) and a van-der-Waals bonded (frozen Ar) target. Clusters with sizes up to N = 10 4 atoms and with energies per atom of E/N = 0.1-1600 eV atom -1 were studied. We find that the stopping force exerted on a cluster follows an N 2/3 -dependence with cluster size N; thus large clusters experience less stopping than equi-velocity atoms. In the course of being stopped, the cluster is strongly deformed and attains a roughly pancake shape. Due to the cluster inertia, maximum deformation occurs later than the maximum stopping force. The time scale of projectile stopping is set by t 0 , the time the cluster needs to cover its own diameter before impacting the target; it thus depends on both cluster size and velocity. The time when the cluster experiences its maximum stopping force is around (0.7-0.8)t 0 . We find that the cluster is deformed with huge strain rates of around 1/2t 0 ; this amounts to 10 11 -10 13 s -1 for the cases studied here. (paper)

    Stop searches in supersymmetric frameworks with R-parity conservation usually assume the lightest neutralino to be the lightest supersymmetric particle. In this paper we consider an alternative scenario in which the left-handed tau sneutrino is lighter than neutralinos and stable at collider scales, but possibly unstable at cosmological scales. Moreover the (mostly right-handed) stop t̃ is lighter than all electroweakinos, and heavier than the scalars of the third generation lepton doublet, whose charged component, τ̃, is heavier than the neutral one, ν̃. The remaining supersymmetric particles are decoupled from the stop phenomenology. In most of the parameter space, the relevant stop decays are only into tτ̃τ, tν̃ν and bν̃τ via off-shell electroweakinos. We constrain the branching ratios of these decays by recasting the most sensitive stop searches. Due to the “double invisible” kinematics of the t̃→tν̃ν process, and the low efficiency in tagging the tτ̃τ decay products, light stops are generically allowed. In the minimal supersymmetric standard model with ∼ 100 GeV sneutrinos, stops with masses as small as ∼ 350 GeV turn out to be allowed at 95% CL.

    A number of environmental impact analyses with the RADTRAN computer code have shown that dose to persons at stops is one of the largest components of incident-free dose during overland carriage of spent fuel and other radioactive materials (e.g., USDOE, 1994). The input data used in these analyses were taken from a 1983 study that reports actual observations of spent fuel shipments by truck. Early RADTRAN stop models, however, were insufficiently flexible to take advantage of the detailed information in the study. A more recent study of gasoline service stations that specialize in servicing large trucks, which are the most likely stop locations for shipments of Type B packages in the United States, has provided additional, detailed data on refueling/meal stops. The RADTRAN 5 computer code for transportation risk analysis allows exposures at stops to be more fully modeled than have previous releases of the code and is able to take advantage of detailed data. It is the intent of this paper first to compare results from RADTRAN and RADTRAN 5 for the old, low-resolution form of input data, and then to demonstrate what effect the new data and input format have on stop-dose estimates for an individual stop and for a hypothetical shipment route. Finally, these estimated public doses will be contrasted with doses calculated for a special population group -- inspectors

    Full Text Available We start proceeding with the stopping time theory in discrete time with the help of the Mizar system [1], [4]. We prove, that the expression for two stopping times k1 and k2 not always implies a stopping time (k1 + k2 (see Theorem 6 in this paper. If you want to get a stopping time, you have to cut the function e.g. (k1 + k2 ⋂ T (see [2, p. 283 Remark 6.14]. Next we introduce the stopping time in continuous time. We are focused on the intervals [0, r] where r ∈ ℝ. We prove, that for I = [0, r] or I = [0,+∞[ the set {A ⋂ I : A ∈ Borel-Sets} is a σ-algebra of I (see Definition 6 in this paper, and more general given in [3, p.12 1.8e]. The interval I can be considered as a timeline from now to some point in the future. This set is necessary to define our next lemma. We prove the existence of the σ-algebra of the τ -past, where τ is a stopping time (see Definition 11 in this paper and [6, p.187, Definition 9.19]. If τ1 and τ2 are stopping times with τ1 is smaller or equal than τ2 we can prove, that the σ-algebra of the τ1-past is a subset of the σ-algebra of the τ2-past (see Theorem 9 in this paper and [6, p.187 Lemma 9.21]. Suppose, that you want to use Lemma 9.21 with some events, that never occur, see as a comparison the paper [5] and the example for ST(1={+∞} in the Summary. We don’t have the element +1 in our above-mentioned time intervals [0, r[ and [0,+1[. This is only possible if we construct a new σ-algebra on ℝ {−∞,+∞}. This construction is similar to the Borel-Sets and we call this σ-algebra extended Borel sets (see Definition 13 in this paper and [3, p. 21]. It can be proved, that {+∞} is an Element of extended Borel sets (see Theorem 21 in this paper. Now we use the interval [0,+∞] as a basis. We construct a σ-algebra on [0,+∞] similar to the book ([3, p. 12 18e], see Definition 18 in this paper, and call it extended Borel subsets. We prove for stopping times with this given σ-algebra, that

    Classically the limit to endurance of exercise is explained in terms of metabolic capacity. Cardio-respiratory capacity and muscle fatigue are thought to set the limit and the majority of studies on factors limiting endurance exercise discuss issues such as maximal oxygen uptake (VO2max), aerobic enzyme capacity, cardiac output, glycogen stores, etc. However, this paradigm does not explain the limitation to endurance exercise with large muscle groups at altitude, when at exhaustion exercise is ended without limb locomotor muscle fatigue and with sub-maximal cardiac output. A simple fact provides a basis for an explanation. Voluntary exercise starts and ends in the brain. It starts with spatial and temporal recruitment of motor units and ends with their de-recruitment. A conscious decision precedes a voluntary effort. The end of effort is again volitional and a forced conscious decision to stop precedes it, but it is unknown what forces the off-switch of recruitment at exhaustion although sensation of exertion certainly plays a role. An alternative model explaining the limitation of exercise endurance thus proposes that the central nervous system integrates input from various sources all related to the exercise and limits the intensity and duration of recruitment of limb skeletal muscle to prevent jeopardizing the integrity of the organism. This model acknowledges the cardio-respiratory and muscle metabolic capacities as prime actors on the performance scene, while crediting the central nervous system for its pivotal role as the ultimate site where exercise starts and ends.

  19. Empirical stopping powers for ions in solids

    International Nuclear Information System (INIS)

    Ziegler, J.F.; Biersack, J.P.; Littmark, U.

    1983-01-01

    The work of Brandt and collaborators on low energy ion stopping powers has been extended to create an empirical formulation for the stopping of ions in solids. The result is a simple computer program (about 60 lines of code) which calculates stopping powers from zero to 100 MeV/amu for all ions in all elemental solids. This code has been compared to the data in about 2000 papers, and has a standard error of 9% for energies above keV/amu. This approach includes high energy relativistic effects and shell-corrections. In the medium energy range it uses stopping theory based on the local-density approximation and Lindhard stopping in a free electron gas. This is applied to realistic Hartree-Fock charge distributions for crystalline solids. In the low energy range it uses the Brandt concepts of ion stripping relative to the Fermi velocity of solids, and also his formalism for the relation of projectile ionization to its effective charge. The details of the calculation are presented, and a broad comparison is shown with experiment. Special comparative examples are shown of both the low energy stopping power oscillations which depend on the atomic number of the ion, and also of the target

  20. Starting physiology: bioelectrogenesis.

    Baptista, Vander

    2015-12-01

    From a Cartesian perspective of rational analysis, the electric potential difference across the cell membrane is one of the fundamental concepts for the study of physiology. Unfortunately, undergraduate students often struggle to understand the genesis of this energy gradient, which makes the teaching activity a hard task for the instructor. The topic of bioelectrogenesis encompasses multidisciplinary concepts, involves several mechanisms, and is a dynamic process, i.e., it never turns off during the lifetime of the cell. Therefore, to improve the transmission and acquisition of knowledge in this field, I present an alternative didactic model. The design of the model assumes that it is possible to build, in a series of sequential steps, an assembly of proteins within the membrane of an isolated cell in a simulated electrophysiology experiment. Initially, no proteins are inserted in the membrane and the cell is at a baseline energy state; the extracellular and intracellular fluids are at thermodynamic equilibrium. Students are guided through a sequence of four steps that add key membrane transport proteins to the model cell. The model is simple at the start and becomes progressively more complex, finally producing transmembrane chemical and electrical gradients. I believe that this didactic approach helps instructors with a more efficient tool for the teaching of the mechanisms of resting membrane potential while helping students avoid common difficulties that may be encountered when learning this topic.

  1. LEP dismantling starts

    CERN Multimedia

    2000-01-01

    Since the end of November, various teams have been getting stuck into dismantling the LEP accelerator and its four experiments. After making the installations safe, the dismantling and removal of 40,000 tonnes of equipment is underway. Down in the tunnel, it is a solemn moment. It is 10 o'clock on 13 December and Daniel Regin, one of those heading the dismantling work, moves in on a magnet, armed with a hydraulic machine. Surrounded by teams gathered there for a course in dismantling, he makes the first cut into LEP. The great deconstruction has begun. In little over than a year, the accelerator will have been cleared away to make room for its successor, the LHC. The start of the operation goes back to 27 November. Because before setting about the machine with hydraulic shears and monkey wrenches, LEP had first to be made safe - it was important to make sure the machine could be taken apart without risk. All the SPS beam injection systems to LEP were cut off. The fluids used for cooling the magnets and superc...

  2. An impressive start

    CERN Multimedia

    2011-01-01

    This has been an excellent week for the LHC, with a succession of fills rapidly increasing the number of proton bunches to 194 per beam. This has allowed the experiments to reach a peak luminosity of 2.5 × 1032 cm-2s-1, thereby surpassing the record for 2010 where we reached 2.0 × 1032 cm-2s-1. At the time of writing, the integrated luminosity delivered by the LHC in 2011 is around 28 inverse picobarns, which is already more than half of the total 2010 dataset.   These are impressive numbers, but what impresses me most is how quickly the LHC operators are now able to turn the machine around between fills, and how well LHC running has been incorporated into the overall operation of CERN’s accelerator complex. The flexibility of the LHC was illustrated on Thursday when we started a short phase of running at 1.38 TeV per beam, equivalent to the energy-per-nucleon of a lead-ion run. This lower energy data will be used by the experiments, in particular by ALICE, to compare...

    The first large active detector component was lowered into the ATLAS cavern on 1st March. It consisted of the 8 modules forming the lower part of the central barrel of the tile hadronic calorimeter. The work of assembling the barrel, which comprises 64 modules, started the following day. Two road trailers each with 64 wheels, positioned side by side. This was the solution chosen to transport the lower part of the central barrel of ATLAS' tile hadronic calorimeter from Building 185 to the PX16 shaft at Point 1 (see Figure 1). The transportation, and then the installation of the component in the experimental cavern, which took place over three days were, to say the least, rather spectacular. On 25 February, the component, consisting of eight 6-metre modules, was loaded on to the trailers. The segment of the barrel was transported on a steel support so that it wouldn't move an inch during the journey. On 26 February, once all the necessary safety checks had been carried out, the convoy was able to leave Buildi...

  4. Inseparability of Go and Stop in Inhibitory Control: Go Stimulus Discriminability Affects Stopping Behavior.

    Ma, Ning; Yu, Angela J

    2016-01-01

    Inhibitory control, the ability to stop or modify preplanned actions under changing task conditions, is an important component of cognitive functions. Two lines of models of inhibitory control have previously been proposed for human response in the classical stop-signal task, in which subjects must inhibit a default go response upon presentation of an infrequent stop signal: (1) the race model, which posits two independent go and stop processes that race to determine the behavioral outcome, go or stop; and (2) an optimal decision-making model, which posits that observers decides whether and when to go based on continually (Bayesian) updated information about both the go and stop stimuli. In this work, we probe the relationship between go and stop processing by explicitly manipulating the discrimination difficulty of the go stimulus. While the race model assumes the go and stop processes are independent, and therefore go stimulus discriminability should not affect the stop stimulus processing, we simulate the optimal model to show that it predicts harder go discrimination should result in longer go reaction time (RT), lower stop error rate, as well as faster stop-signal RT. We then present novel behavioral data that validate these model predictions. The results thus favor a fundamentally inseparable account of go and stop processing, in a manner consistent with the optimal model, and contradicting the independence assumption of the race model. More broadly, our findings contribute to the growing evidence that the computations underlying inhibitory control are systematically modulated by cognitive influences in a Bayes-optimal manner, thus opening new avenues for interpreting neural responses underlying inhibitory control.

  6. Stopping, goal-conflict, trait anxiety and frontal rhythmic power in the stop-signal task.

    2011-12-01

    The medial right frontal cortex is implicated in fast stopping of an initiated motor action in the stop-signal task (SST). To assess whether this region is also involved in the slower behavioural inhibition induced by goal conflict, we tested for effects of goal conflict (when stop and go tendencies are balanced) on low-frequency rhythms in the SST. Stop trials were divided, according to the delays at which the stop signal occurred, into short-, intermediate-, and long-delay trials. Consistent with goal-conflict processing, intermediate-delay trials were associated with greater 7-8 Hz EEG power than short- or long-delay trials at medial right frontal sites (Fz, F4, and F8). At F8, 7-8 Hz power was linked to high trait anxiety and neuroticism. A separate 4-7 Hz power increase was also seen in stop, relative to go, trials, but this was independent of delay, was maximal at the central midline site Cz, and predicted faster stopping. Together with previous data on the SST, these results suggest that the right frontal region could be involved in multiple inhibition mechanisms. We propose a hierarchical model of the control of stopping that integrates the literature on the neural control of fast motor stopping with that on slower, motive-directed behavioural inhibition.

  7. Cancer-Related Worry and Physical Well-Being in the Context of Perceived Stress in Young Adults with Testicular Cancer.

    2017-06-01

    Uncertainty associated with cancer can foster future-focused worry and ultimately diminish physical well-being, especially among young adult survivors. Stress perceptions might exacerbate the association of worry and physical well-being. Young adults with testicular cancer (N = 171) completed measures of physical well-being, perceived stress, and future cancer-related worry. Perceived stress and future worry were both negatively associated with physical well-being. Perceived stress moderated the relationship; more perceived stress was related to lower physical well-being in those with high worry. Interventions aimed at worry reduction might benefit from reducing global stress perceptions.

  8. The Relationship of Behavioral Activation and Inhibition Systems (BAS/BIS, Difficulty of Emotional Regulation, Metacognition with Worry

    2014-11-01

    Full Text Available Worry is a popular phenomenon and a common feature of many disorders, especially anxiety disorders. The objective of the study was to predict worry by using three predictive factors related to biological, emotional and cognition areas. In this study, behavioral inhibition, behavioral activation system, difficulties in emotion regulation and metacognition were examined as predictive variables. In a correlation cross-sectional design, 234 Medical Group students [BA and MA] of Tehran University of Medical Sciences participated in this study by using cluster sampling. The students completed these scales: Behavioral Inhibition and Behavioral Activation Systems (BAS/BIS, Difficulty of Emotion Regulation Scale (DERS, Metacognition Questionnaire-30 (MCQ-30 and Penn State Worry Questionnaire (PSWQ. Behavioral inhibition system, difficulty of emotion rgulation and metacognition variables were significantly positively correlated with worry (P<0/0 1(. Behavioral activation system variable was not significantly associated with worry. Stepwise multiple regression analysis indicated a predictive model for worry in which behavioral inhibition system, difficulty of emotional regulation and metacognition were its components respectively. Behavioral activation system was not included in the model. The findings of this study that worry should be studied in different biological, emotional, and metacognitive aspects. The results also emphasize the role of behavioral inhibition system as a temperamental and biological factor in psychopathology of worry in adult population.

    There is increasing interest in combining postmenopausal hormone therapy (HT) and SERMs in midlife women. We previously showed that refusal to participate in a prevention trial of low dose tamoxifen in HT users was associated with higher worry about breast cancer. Given this counterintuitive finding, we studied which factors influenced worry and risk perception of breast cancer. We assessed the relationships of breast cancer worry and risk perception with age, age at menopause, Gail risk, education, adherence to mammographic screening, BMI, smoking, physical activity, alcohol use, anxiety and depression in 457 midlife HT users who were eligible to participate in the trial. Women with menopause 52 years (OR = 5.0, 95% CI, 1.2-21.1). Worry was also associated with high absolute risk perception and former smoking. Factors associated with higher risk perception were age>60 years, at-risk life style, worry about breast cancer and depression. The inverse association between early menopause and worry about breast cancer is in contrast with the known protective effect of early menopause on breast cancer risk and seems to reflect a feeling of aging and disease vulnerability. Our findings indicate that worry about cancer has an affective construct which is independent of breast cancer biology but is engaged in health decision making. Increasing breast cancer risk awareness in subjects high in worry without a plan of emotional coping may therefore be counterproductive because of avoidant attitudes. Copyright © 2017.

    During the fall of 2014, the threat of an Ebola outbreak gripped the United States (Poll, 8-12 October 2014; see Harvard School of Public Health & SSRS, 2014), creating a unique opportunity to advance basic knowledge concerning how emotion regulation works in consequential contexts and translate existing research in this area to inform public health and policy. We addressed these issues by examining whether third-person self-talk, a simple technique that promotes emotion regulation, could nudge people into reasoning about Ebola more rationally. In all, 1,257 people from across the United States were asked to write about their feelings about Ebola using their name or I (i.e. third-person self-talk vs. first-person self-talk) as concerns about Ebola swelled (24 October 2014-26 October 2014). Third-person self-talk led participants who scored high on Ebola worry at baseline to generate more fact-based reasons not to worry about Ebola, which predicted reductions in their Ebola worry and risk perception. These findings held when controlling for several theoretically relevant covariates, highlighting their robustness. These results demonstrate how a simple linguistic technique can enhance rational thinking and quell worry about a pressing public health threat. © 2017 The International Association of Applied Psychology.

    2012-08-01

    Full Text Available The present study evaluated the relations between anxious attachment styles and rejection sensitivity, and the potential mediating role of self-esteem and worry. A sample of 125 Iranian college students completed surveys assessing rejection sensitivity, attachment style, worry and self-esteem. Structural Equation Modeling (SEM analyses were conducted. Results show that there is a significant positive relationship between anxious attachment styles and rejection sensitivity. The study suggests that a higher score in anxious attachment styles is associated with a higher level of worry and lower level of self-esteem and it is also associated with higher level of rejection sensitivity. Furthermore, there is a positive significant relationship between worry and rejection sensitivity and there is a negative significant relationship between self-esteem and rejection sensitivity. Results indicate that self-esteem and worry mediate the relationship between anxious attachment styles and rejection sensitivity.

    Duchenne muscular dystrophy (DMD) is a progressive, fatal pediatric disorder with significant burden on parents. Assessing disease impact can inform clinical interventions. Best-worst scaling (BWS) was used to elicit parental priorities among 16 short-term, DMD-related worries identified through community engagement. Respondents viewed 16 subsets of worries, identified using a balanced, incomplete block design, and identified the most and least worrying items. Priorities were assessed using best-worst scores (spanning +1 to -1) representing the relative number of times items were endorsed as most and least worrying. Independent-sample t-tests compared prioritization of parents with ambulatory and non-ambulatory children. Participants (n = 119) most prioritized worries about weakness progression (BW score = 0.64) and getting the right care over time (BW = 0.25). Compared to parents of non-ambulatory children, parents of ambulatory children more highly prioritized missing treatments (BW = 0.31 vs. 0.13, p < 0.001) and being a good enough parent (BW = 0.06 vs. -0.08, p = 0.010), and less prioritized child feeling like a burden (BW = -0.24 vs. -0.07, p < 0.001). Regardless of child's disease stage, caregiver interventions should address the emotional impact of caring for a child with a progressive, fatal disease. We demonstrate an accessible, clinically-relevant approach to prioritize disease impact using BWS, which offers an alternative to the use of traditional rating/ranking scales.

    Many supersymmetric models such as the constrained minimal supersymmetric extension of the Standard Model (CMSSM) feature a strip in parameter space where the lightest neutralino χ is identified as the lightest supersymmetric particle, the lighter stop squark t{sub 1} is the next-to-lightest supersymmetric particle (NLSP), and the relic χ cold darkmatter density is brought into the range allowed by astrophysics and cosmology by coannihilation with the lighter stop squark t{sub 1} NLSP. We calculate the stop coannihilation strip in the CMSSM, incorporating Sommerfeld enhancement effects, and we explore the relevant phenomenological constraints and phenomenological signatures. In particular, we show that the t{sub 1} may weigh several TeV, and its lifetime may be in the nanosecond range, features that are more general than the specific CMSSM scenarios that we study in this paper.

  3. The stopping rules for winsorized tree

    2017-11-01

    Winsorized tree is a modified tree-based classifier that is able to investigate and to handle all outliers in all nodes along the process of constructing the tree. It overcomes the tedious process of constructing a classical tree where the splitting of branches and pruning go concurrently so that the constructed tree would not grow bushy. This mechanism is controlled by the proposed algorithm. In winsorized tree, data are screened for identifying outlier. If outlier is detected, the value is neutralized using winsorize approach. Both outlier identification and value neutralization are executed recursively in every node until predetermined stopping criterion is met. The aim of this paper is to search for significant stopping criterion to stop the tree from further splitting before overfitting. The result obtained from the conducted experiment on pima indian dataset proved that the node could produce the final successor nodes (leaves) when it has achieved the range of 70% in information gain.

  4. Electron stopping powers for transport calculations

    The reliability of radiation transport calculations depends on the accuracy of the input cross sections. Therefore, it is essential to review and update the cross sections from time to time. Even though the main interest of the author's group at NBS is in transport calculations and their applications, the group spends almost as much time on the analysis and preparation of cross sections as on the development of transport codes. Stopping powers, photon attenuation coefficients, bremsstrahlung cross sections, and elastic-scattering cross sections in recent years have claimed attention. This chapter deals with electron stopping powers (with emphasis on collision stopping powers), and reviews the state of the art as reflected by Report 37 of the International Commission on Radiation Units and Measurements

    Full Text Available In 1967, at the International and Universal Exposition (Expo 67 in Montreal, American government planners and their collaborators in the private sector revolutionized how the United States participated at world's fairs. They transformed the ways in which architecture, design, and exhibits could come together in a stunning visual endpoint. The choice of 1960s social visionary and design guru F. Buckminster Fuller’s geodesic dome (“Bucky’s Bubble” for the US Pavilion structure proved a coup, as did the Marshall McLuhan-inspired Cambridge Seven design team that created the Pavilion interior of platforms joined by criss-crossing bridges and escalators. This article incorporates an analysis of four linked elements of the US Expo 67 design project. First, it conceives of the US Pavilion at the edge of US empire. Second, it suggests that, improbably, planners found success in the mix of earlier world’s fair grand designs with a new minimalist modernity. Third, Pavilion design and content reflected the influence of Andy Warhol and other artists whose work was transforming gay camp into mass camp in American popular culture. Finally, the project drew on a secret World War II US army collaboration between three key Expo 67 planners, whose wartime specialty had been in military deception, to complete the visual revolution at the US Pavilion.

    This paper investigates the effects of school starting age on crime while relying on variation in school starting age induced by administrative rules; we exploit that Danish children typically start first grade in the calendar year they turn seven, which gives rise to a discontinuity in children......’s school starting age. Analyses are carried out using register-based Danish data. We find that higher age at school start lowers the propensity to commit crime, but that this reduction is caused by incapacitation while human capital accumulation is unaffected.

    The critical importance of the start phase in bicycle motocross (BMX) racing is increasingly acknowledged. Past experiments underlined that the internal lane of the starting gate provides a strong positional advantage. However, how lane position affects start performance and cognitive and somatic state anxiety remains unexplored. We examined the start performance and anxiety responses of youth national-level BMX riders in both experimental and ecological contexts. We used contextualization motor imagery routines to evaluate start performance and state anxiety from the internal and external lanes. Cycle ergometer measures revealed a better start performance from the external lane, but we did not record any lane effect on actual gate start times. Both somatic and cognitive anxiety scores were higher before racing from the internal compared to the external lane. Finally, state anxiety (i.e., somatic anxiety, worry and concentration disruptions) negatively predicted the start performance. Present findings provide original insights on psychological factors involved in BMX start performance, and might contribute to fruitful coping interventions and training programmes in sports overlapping the framework of "handicap races" taking the specific form of positional advantages/disadvantages at the start (e.g., ski/snowboard cross, athletics, swimming, motorsports, etc.).

    1989-01-01

    In the regulated world of nuclear power, the need to have analytical proof of performance in hypothetical design-basis events such as earth quakes has placed a premium on design configurations that are mathematically tractable and easily analyzed. This is particularly true for the piping design. Depending on how the piping analyses are organized and on how old the plant is, there may be from 200 to 1000 separate piping runs to be designed, analyzed, and qualified. In this situation, the development of snubbers seemed like the answer to a piping engineer's prayer. At any place where seismic support was required but thermal motion had to be accommodated, a snubber could be specified. But, as experience has now shown, the program was solved only on paper. This article presents an alternative to conventional snubbers. These new devices, termed Seismic Stops are designed to replace snubbers directly and look like snubbers on the outside. But their design is based on a completely different principle. The original concept has adapted from early seismic-resistant pipe support designs used on fossil power plants in California. The fundamental idea is to provide a space envelope in which the pipe can expand freely between the hot and cold positions, but cannot move outside the envelope. Seismic Stops are designed to transmit any possible impact load, as would occur in an earthquake, away from the pipe itself to the Seismic Stop. The Seismic Stop pipe support is shown

  16. Are Stopped Strings Preferred in Sad Music?

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available String instruments may be played either with open strings (where the string vibrates between the bridge and a hard wooden nut or with stopped strings (where the string vibrates between the bridge and a performer's finger pressed against the fingerboard. Compared with open strings, stopped strings permit the use of vibrato and exhibit a darker timbre. Inspired by research on the timbre of sad speech, we test whether there is a tendency to use stopped strings in nominally sad music. Specifically, we compare the proportion of potentially open-to-stopped strings in a sample of slow, minor-mode movements with matched major-mode movements. By way of illustration, a preliminary analysis of Samuel Barber's famous Adagio from his Opus 11 string quartet shows that the selected key (B-flat minor provides the optimum key for minimizing open string tones. However, examination of a broader controlled sample of quartet movements by Haydn, Mozart and Beethoven failed to exhibit the conjectured relationship. Instead, major-mode movements were found to avoid possible open strings more than slow minor-mode movements.

    Shukri, Abdullah-Atef

    2015-01-01

    The average energy loss of an ion per unit path length when it is moving through the matter is named the stopping power. The knowledge of the stopping power is essential for a variety of contemporary applications which depend on the transport of ions in matter, especially ion beam analysis techniques and ion implantation. Most noticeably, the use of proton or heavier ion beams in radiotherapy requires the knowledge of the stopping power. Whereas experimental data are readily available for elemental solids, the data are much more scarce for compounds. The linear response dielectric formalism has been widely used in the past to study the electronic stopping power. In particular, the famous pioneering calculations due to Lindhard evaluate the electronic stopping power of a free electron gas. In this thesis, we develop a fully ab initio scheme based on linear response time-dependent density functional theory to predict the impact parameter averaged quantity named the random electronic stopping power (RESP) of materials without any empirical fitting. The purpose is to be capable of predicting the outcome of experiments without any knowledge of target material besides its crystallographic structure. Our developments have been done within the open source ab initio code named ABINIT, where two approximations are now available: the Random-Phase Approximation (RPA) and the Adiabatic Local Density Approximation (ALDA). Furthermore, a new method named 'extrapolation scheme' have been introduced to overcome the stringent convergence issues we have encountered. These convergence issues have prevented the previous studies in literature from offering a direct comparison to experiment. First of all, we demonstrate the importance of describing the realistic ab initio electronic structure by comparing with the historical Lindhard stopping power evaluation. Whereas the Lindhard stopping power provides a first order description that captures the general features of the

    2009-03-01

    The age-appropriate Sport Anxiety Scale-2 (SAS-2; Smith, Smoll, Cumming, & Grossbard, 2006) was used to assess levels of cognitive and somatic anxiety among male and female youth sport participants. Confirmatory factor analyses with a sample of 9-14 year old athletes (N=1038) supported the viability of a three-factor model of anxiety involving somatic anxiety, worry, and concentration disruption previously demonstrated in high school and college samples. Tests for factorial invariance revealed that the three-factor model was an equally good fit for 9-11 year olds and 12-14 year olds, and for both males and females. Gender and age were modestly related to anxiety scores. Worry about performing poorly was highest in girls and in older athletes, whereas boys reported higher levels of concentration disruption in competitive sport situations. Implications for emotional perception and for the study of competitive anxiety in young athletes are discussed.

    Psychosocial problems are frequent among patients with psoriasis. The aim of this study was to analyse the prevalence of some specific psychosocial issues. These were evaluated in 936 patients using the emotions and functioning scales of the Skindex-29 questionnaire. The problems most frequently experienced were: shame, anger, worry, difficulties in daily activities and social life. All problems were associated with the severity of psoriasis and with depression or anxiety. Shame, worry and annoyance were more frequent in women than in men, and shame and anger were associated with a low level of education. Impairment in work/hobbies was significantly higher in patients with palmoplantar psoriasis and those with arthro-pathic psoriasis. In conclusion, clinicians could gain important insights about their patients by looking at the single items of a quality of life instrument, to identify patients with high levels of emotional and social problems, in order to improve quality of care.

    International Nuclear Information System (INIS)

    Tsakmakidis, Kosmas L.; Hess, Ortwin

    2012-01-01

    We present an overview of recent advances within the field of slow- and stopped-light in metamaterial and plasmonic waveguides. We start by elucidating the mechanisms by which these configurations can enable complete stopping of light. Decoherence mechanisms may destroy the zero-group-velocity condition for real-frequency/complex-wavevector modes, but we show that metamaterial and nanoplasmonic waveguides also support complex-frequency/real-wavevector modes that uphold the light-stopping condition. A further point of focus is how, by using gain, dissipative losses can be overcome in the slow- and stopped-light regimes. To this end, on the basis of full-wave finite-difference time-domain (FDTD) simulations and analytic transfer-matrix calculations, we show that the incorporation of thin layers made of an active medium, placed adjacently to the core layer of a negative-refractive-index waveguide, can fully remove dissipative losses - in a slow- or stopped-light regime where the effective index of the guided lightwave remains negative.

    Full Text Available This study examined stopping and performance adjustments in four age groups (M ages: 8, 12, 21, and 76 years. All participants performed on three tasks, a standard two-choice task and the same task in which stop-signal trials were inserted requiring either the suppression of the response activated by the choice stimulus (global stop task or the suppression of the response when one stop signal was presented but not when the other stop signal occurred (selective stop task. The results showed that global stopping was faster than selective stopping in all age groups. Global stopping matured more rapidly than selective stopping. The developmental gain in stopping was considerably more pronounced compared to the loss observed during senescence. All age groups slowed the response on trials without a stop signal in the stop task compared to trials in the choice task, the elderly in particular. In addition, all age groups slowed on trials following stop-signal trials, except the elderly who did not slow following successful inhibits. By contrast, the slowing following failed inhibits was disproportionally larger in the elderly compared to young adults. Finally, sequential effects did not alter the pattern of performance adjustments. The results were interpreted in terms of developmental change in the balance between proactive and reactive control.

  11. Women with urinary incontinence: self-perceived worries and general practitioners' knowledge of problem.

    Lagro-Janssen, T L; Smits, A J; Van Weel, C

    1990-01-01

    In the context of a large scale survey of health problems in women aged 50 to 65 years, a study was undertaken on the effects of incontinence on daily life. For this purpose 1442 women randomly selected from the practice files of 75 general practitioners in the eastern part of the Netherlands were interviewed at home (response rate 60%). In cases of moderate or severe incontinence the general practitioner of the woman concerned was asked whether this problem had been diagnosed in general practice. Incontinence was reported in 22.5% of the women. Overall, 77.8% of the women did not feel worried about it and 75.4% did not feel restricted in their activities; even for women with severe incontinence (daily frequency and needing protective pads) only 15.6% experienced much worry and 15.7% much restriction. About a third of the women with incontinence (32.0%) had been identified by their general practitioner. The greater the worries and restrictions owing to incontinence, the greater the chance that the incontinence was known to the general practitioner concerned.

    High comorbidity rates among emotional disorders have led researchers to examine transdiagnostic factors that may contribute to shared psychopathology. Bifactor models provide a unique method for examining transdiagnostic variables by modelling the common and unique factors within measures. Previous findings suggest that the bifactor model of the Depression Anxiety and Stress Scale (DASS) may provide a method for examining transdiagnostic factors within emotional disorders. This study aimed to replicate the bifactor model of the DASS, a multidimensional measure of psychological distress, within a US adult sample and provide initial estimates of the reliability of the general and domain-specific factors. Furthermore, this study hypothesized that Worry, a theorized transdiagnostic variable, would show stronger relations to general emotional distress than domain-specific subscales. Confirmatory factor analysis was used to evaluate the bifactor model structure of the DASS in 456 US adult participants (279 females and 177 males, mean age 35.9 years) recruited online. The DASS bifactor model fitted well (CFI = 0.98; RMSEA = 0.05). The General Emotional Distress factor accounted for most of the reliable variance in item scores. Domain-specific subscales accounted for modest portions of reliable variance in items after accounting for the general scale. Finally, structural equation modelling indicated that Worry was strongly predicted by the General Emotional Distress factor. The DASS bifactor model is generalizable to a US community sample and General Emotional Distress, but not domain-specific factors, strongly predict the transdiagnostic variable Worry.

    According to the predictions of attentional control theory (ACT) of anxiety (Eysenck, Derakshan, Santos, & Calvo, 2007), worry is a central feature of anxiety that interferes with the ability to inhibit distracting information necessary for successful task performance. However, it is unclear how such cognitive control deficits are modulated by task demands and by the emotionality of the distractors. A sample of 31 participants (25 female) completed a novel flanker task with emotional and neutral distractors under low- and high-cognitive-load conditions. The negative-going N2 event-related potential was measured to index participants' level of top-down resource allocation in the inhibition of distractors under high- and low-load conditions. Results showed N2 amplitudes were larger under high- compared with low-load conditions. In addition, under high but not low load, trait worry was associated with greater N2 amplitudes. Our findings support ACT predictions that trait worry adversely affects goal-directed behavior, and is associated with greater recruitment of cognitive resources to inhibit the impact of distracting information under conditions in which cognitive resources are taxed.

    To investigate whether parental worry about their children's health predicts usage of a pediatric Internet intervention for encopresis. Thirty-nine families with a child diagnosed with encopresis completed a national clinical trial of an Internet-based intervention for encopresis (www.ucanpooptoo.com). Parents rated worry about their children's health, encopresis severity, current parent treatment for depression, and parent comfort with the Internet. Usage indicators were collected while participants utilized the intervention. Regression analyses showed that parents who reported higher baseline levels of worry about their children's health showed greater subsequent intervention use (beta =.52, p =.002), even after accounting for other plausible predictors. Exploratory analyses indicated that this effect may be stronger for families with younger children. Characteristics of individuals using Internet-based treatment programs, such as parental worry about their children's health, can influence intervention usage, and should be considered by developers of Internet interventions.

We sought to promote patient-focused drug development (PFDD for AML by developing and piloting an instrument to prioritize the worries of patients with AML.Patients and methods: An innovative community-centered approach was used to engage expert and community stakeholders in the development, pretesting, pilot testing, and dissemination of a novel best–worst scaling instrument. Patient worries were identified through individual interviews (n=15 and group calls. The instrument was developed through rigorous pretesting (n=13 and then piloted among patients and caregivers engaged in this study (n=25. Priorities were assessed using best–worst scores (spanning from +1 to -1 representing the relative number of times that items were endorsed as the most and the least worrying. All findings were presented at a PFDD meeting at the US Food and Drug Administration (FDA that was attended by >80 stakeholders. Results: The final instrument included 13 worries spanning issues such as decision making, treatment delivery, physical impacts, and psychosocial effects. Patients and caregivers most prioritized worries about dying from their disease (best minus worst [BW] score=0.73, long-term side effects (BW=0.28, and time in hospital (BW=0.25.Conclusion: Community-centered approaches are valuable in designing and executing PFDD meetings and associated quantitative surveys to document the experience of patients.

    As the material in an ICF target is heated and ionized by an intense ion beam, the ion stopping power changes from that of neutral atoms. This changes the energy deposition characteristics of the ion beam and thereby can profoundly influence the target dynamics. An accurate ion energy deposition model is important for designing ICF targets that perform in an optimal fashion. An experiment to measure a time-resolved ion stopping power history in a partially ionized target is being fielded on the PROTO I accelerator at Sandia Labs. This experiment utilizes a voltage ramped Thomson parabola to provide a time-history of the ion energy incident upon and exiting from a cylindrical target foil

    The stopping power of light ions penetrating various materials has been measured. The data of proton stopping power and the mean ionization potentials are presented. The experiments were made by using the 6.75 MeV protons from a cyclotron and the protons in the energy range from 3 to 9 MeV from a tandem Van de Graaff. The windows with and without sample-foils were rotated in front of a semiconductor detector, and the measured energy loss and the thickness of the sample foils were used to estimate the energy loss at the mean energy of protons in the samples. The analyses were made by considering the inner shell correction, Z 1 3 correction and the Bloch correction. The mean ionization potentials were derived from the data. (Kato, T.)

    Recent p + A → p + X data are analyzed within the context of the multi-chain and additive quark models. We deduce the average energy loss of a baryon as a function of distance traversed in nuclear matter. Consistency of the multi-chain model is checked by comparing the predictions for p + A → π +- + X with data. We discuss the space-time development of baryon stopping and show how longitudinal growth limits the energy deposition per unit length. Predictions are made for the proton spectra to be measured in nucleus-nucleus collisions at CERN and BNL. Finally, we conclude that the stopping domain for central collisions of heavy ions extends up to center of mass kinetic energies KEsub(em) asymptotically equals 3 +- 1 AGev. (author)

    Calculations of electron mass stopping power (SP) of electrons in H2 have been performed using the convergent close-coupling method for incident electron energies up to 2000 eV. Convergence of the calculated SP has been established by increasing the size of the close-coupling expansion from 9 to 491 states. Good agreement was found with the SP measurements of Munoz et al. [Chem. Phys. Lett. 433, 253 (2007), 10.1016/j.cplett.2006.10.114].

    Pion momentum spectra from K - absorption at rest on various nuclear targets were measured by means of a magnetic spectrometer with wide momentum range (100 ∼ 300 MeV/c). The ground state of Σ - hypernucleus, if well bound with a narrow width, is expected to be populated in 12 C(stopped K - , π + ) inclusive (untagged) spectrum, but such a peak was not observed. The spectrum is compared with the DWIA calculations by Morimatsu and Yazaki, indicating that the depth of the nuclear potential of Σ - is shallower than 12 MeV, and that its imaginary part is larger than 5 MeV if the potential depth is about 10 MeV. In the 12 C(stopped K - , π - ) spectrum, the ground state ((p3/2) n -1 (s1/2) Λ ) and the excited states ((p3/2) n -1 (p) Λ ) of Λ 12 C were observed, and their formation probabilities were roughly in agreement with the results of DWIA calculations. In the π - spectra on 12 C, 9 Be, and 7 Li targets a distinct peak was observed at 132.1 ± 0.7 MeV/c. It is ascribed to π - from the mesic decay of Λ 4 H; Λ 4 H → 4 He π - . The formation probability of Λ 4 H on C, Be, or Li target is much larger than those of the discrete states of Λ 12 C via the direct (stopped K - , π - ) reaction. (author)

  7. Evidence for Transdiagnostic Repetitive Negative Thinking and Its Association with Rumination, Worry, and Depression and Anxiety Symptoms: A Commonality Analysis

    Directory of Open Access Journals (Sweden)

    Daniel E. Gustavson

    2018-05-01

    Full Text Available Recent theoretical advances have emphasized the commonality between rumination and worry, often referred to as repetitive negative thinking. Although not studied extensively, repetitive negative thinking may not only account for a substantial overlap between depression and anxiety symptoms but also encapsulate other constructs including one’s tendency to experience unwanted intrusive thoughts or have low levels of mindfulness. In this study, 643 college students completed self-report questionnaire measures of repetitive negative thinking (the Habit Index of Negative Thinking and other relevant constructs including rumination, worry, depression and anxiety symptoms, intrusive thoughts, and mindfulness. To analyze the data, we conducted systematic commonality analyses, which algebraically decomposed shared variances among these measures into various unique components. Results in Study 1 indicated that individual differences in repetitive negative thinking were explained largely by the overlap between rumination and worry, but also by some rumination-specific and worry-specific variance. Moreover, the shared variation in rumination and worry explained the frequencies of depression and anxiety symptoms and their overlap. We also found in Study 2 that repetitive negative thinking was positively related to intrusive thoughts and negatively related to mindfulness. These associations were mostly explained by shared variance with rumination and worry, but there was also some mindfulness-specific variance. These results suggest that repetitive negative thinking may indeed lie at the core of the comorbidity between depression and anxiety symptoms, but that it is also a broader construct that encompasses intrusive thoughts and low levels of mindfulness.

  8. Effects of worry on physiological and subjective reactivity to emotional stimuli in generalized anxiety disorder and nonanxious control participants.

    2010-10-01

    The present study examined the effect of worry versus relaxation and neutral thought activity on both physiological and subjective responding to positive and negative emotional stimuli. Thirty-eight participants with generalized anxiety disorder (GAD) and 35 nonanxious control participants were randomly assigned to engage in worry, relaxation, or neutral inductions prior to sequential exposure to each of four emotion-inducing film clips. The clips were designed to elicit fear, sadness, happiness, and calm emotions. Self reported negative and positive affect was assessed following each induction and exposure, and vagal activity was measured throughout. Results indicate that worry (vs. relaxation) led to reduced vagal tone for the GAD group, as well as higher negative affect levels for both groups. Additionally, prior worry resulted in less physiological and subjective responding to the fearful film clip, and reduced negative affect in response to the sad clip. This suggests that worry may facilitate avoidance of processing negative emotions by way of preventing a negative emotional contrast. Implications for the role of worry in emotion avoidance are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

    This study was designed to assess whether the symptoms of posttraumatic stress mediate or moderate the relationship between political stressors and emotional and behavioral disorders in Palestinian children. It was hypothesized that (a) posttraumatic stress and worry mediate the effect of political stressors on behavioral and emotional disorders and (b) the relationship between political stressors and behavioral and emotional disorders should be attenuated for children with low levels of worry and posttraumatic stress and strengthened for children with high levels of worry and posttraumatic stress. The total sample was 1267 school age children of both sexes with a mean age of 11.97 years. Interviews were conducted with children at school. As hypothesized, the results indicated that posttraumatic stress and worry mediated and moderated the relationship between political stressors and emotional and behavioral disorders in children. Cognitive-behavioral therapy may be used to reduce the incidence of posttraumatic stress and decrease self-reported worry, somatic symptoms, general anxiety, and depression among children exposed to political trauma. Cognitive-behavioral treatment that exclusively targets excessive worry can lead to clinical change in the other interacting subsystems at the cognitive, physiological, affective and behavioral levels.

  10. “Her Life Rests on Your Shoulders”: Doing Worry as Emotion Work in the Care of Children With Diabetes

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Research on parents’ caregiving experiences in the context of diabetes management have consistently shown that parents experience high levels of pediatric parenting stress, anxiety, depression, and general worry. However, how parents understand their worry is largely unexplored and little attention is paid to the work parents are already actively doing to manage their worry. Adopting Arlie Hochschild’s concept of “emotion work” and Dorothy Smith’s concept of “work,” this article examines how parents engage in the emotion work of doing worry. Drawing on the analysis of transcribed data from interviews with seven parents caring for children with diabetes, I show how parents expressed worry as an emotion they experience as well as an embodied way of knowing the presence of potential threats to their child’s health. Thus, doing worry is an essential aspect of work done by parents to ensure the safety and well-being of their children with diabetes.

    2015-01-01

    To determine whether five psychosocial variables, namely, religiosity, morality, perceived promiscuity, cancer worry frequency, and cancer worry severity, predict young women's intentions to receive the human papillomavirus (HPV) vaccination. Female undergraduate students (n=408) completed an online survey. Questions pertaining to hypothesized predictors were analyzed through bivariate correlations and hierarchical regression equations. Regressions examined whether the five psychosocial variables of interest predicted intentions to vaccinate above and beyond controls. Proposed interactions among predictor variables were also tested. Study findings supported cancer worry as a direct predictor of HPV vaccination intention, and religiosity and sexual experience as moderators of the relationship between concerns of promiscuity reputation and intentions to vaccinate. One dimension of cancer worry (severity) emerged as a particularly robust predictor for this population. This study provides support for several important, yet understudied, factors contributing to HPV vaccination intentions among college-aged women: cancer worry severity and religiosity. Future research should continue to assess the predictive contributions of these variables and evaluate how messages and campaigns to increase HPV vaccination uptake can utilize religious involvement and worry about cancer to promote more effectively HPV vaccination as a cancer prevention strategy.

In Chapter 2 we consider a general geometric Lévy process and solve the non-linear optimal stopping problem of maximizing the variance at the stopping time. For solving this problem...... we solve an auxiliary quadratic optimal stopping problem. We show that the solution to maximizing variance depends on whether randomized stopping times are included in the set of stopping times we maximize over. For some problems the inclusion of randomized stopping times increase the value function...... and for some it does not. Even when the value function is not affected by inclusion of randomized stopping times, a solution may be easier to identify when they are. In Chapter 3 we consider the non-linear optimal stopping problem of maximizing the mean minus a positive constant times the variance...

  17. Public worry and question about radiation hazard. Analysis of JHPS web-site opinion on Fukushima I accident

    International Nuclear Information System (INIS)

    Shimo, Michikuni

    2011-01-01

    This is a tentative interim report of worry and question appeared in Japan Health Physics Society (JHPS) web-site, which formally started from Mar. 25 in 2011 and had origins of voluntary activity by JHPS members from Mar. 16 and of subsequent Japan MECSST requirement on Mar. 18 concerning the Fukushima Daiichi Power Plant Accident (Fukushima I, Mar. 12). Replying to the health risk in the web essentially stood on the stance that the risk always exists, uncertainty is not unavoidable and risk concerns about public, not about individuals. Major two problems generated were solved by the answering with the manager name not with the responsible individual expert, and by the careful, detailed explanation (long sentence) about the safety dose standards. Questioners were thought mostly to be women of ages between 20 and 40 y. Their living addresses written were Tokyo, Chiba, Fukushima areas and so on, although they were mostly unwritten. The number of questions was 709 (10/day) until July 1; their major three items, when classified in 48, were related to the comparison with the nuclear explosion experiments, Chernobyl Accident and released nuclides from the Fukushima I; and their major key words contained were child (39 questions), health hazard and concern (25), food and water (16), etc. It has become clear that sufficient carefulness is necessary in telling non-experts who scarcely have the fundamental, systematic and mechanistic knowledge, about the assessment of the radiation health risk, where quantitativeness is highly important. The author hopes to publish answers not only as a documentary of the Accident but also as a system of concerned knowledge. (T.T.)

    2014-01-01

    Purpose: In ion beam therapy electronic stopping power data enter in different disciplines, e.g., dose planning, dosimetry, and radiobiology. However, relevant stopping power data are only known within an accuracy of 2%-10%. We started the software library project libdEdx to unify data from several well-known stopping power sources into one ready-to-use package being 1) freely available and 2) easy accessible via a web-based front end. Methods: Currently, stopping power data from PSTAR, ASTAR, MSTAR and ICRU49+73 are implemented along with a version of the Bethe formula. The library is programmed in the language C to provide broad portability and high performance. A clean API provides full access to the underlying functions and thread safety in multi-threaded applications. The possibility to define arbitrary materials complements the list of predefined ICRU materials. Furthermore, we introduced a collection of tools, e.g., inverse stopping power look-up as well as CSDA range calculation and its inverse. Results: On a standard desktop PC libdEdx calculates 22 million look-ups/sec. A web GUI (available at http://dedx.au.dk) provides easy access to libdEdx and download of stopping data and graphs. For compounds, we observe that stopping power data are robust for variations in the mean excitation potential of the constituents as long as the total mean excitation potential is fixated. Conclusion: We released libdEdx (version number 1.2.1: http://sf.net/projects/libdedx/) with a web-based GUI. Future development will focus on implementing further stopping powers sources (e.g., for electrons and nuclear stopping) and relativistic effects.

  19. Biobjective Optimization and Evaluation for Transit Signal Priority Strategies at Bus Stop-to-Stop Segment

    Directory of Open Access Journals (Sweden)

    Rui Li

    2016-01-01

    Full Text Available This paper proposes a new optimization framework for the transit signal priority strategies in terms of green extension, red truncation, and phase insertion at the stop-to-stop segment of bus lines. The optimization objective is to minimize both passenger delay and the deviation from bus schedule simultaneously. The objective functions are defined with respect to the segment between bus stops, which can include the adjacent signalized intersections and downstream bus stops. The transit priority signal timing is optimized by using a biobjective optimization framework considering both the total delay at a segment and the delay deviation from the arrival schedules at bus stops. The proposed framework is evaluated using a VISSIM model calibrated with field traffic volume and traffic signal data of Caochangmen Boulevard in Nanjing, China. The optimized TSP-based phasing plans result in the reduced delay and improved reliability, compared with the non-TSP scenario under the different traffic flow conditions in the morning peak hour. The evaluation results indicate the promising performance of the proposed optimization framework in reducing the passenger delay and improving the bus schedule adherence for the urban transit system.

    2012-03-01

    The goal of the present study was to investigate a threat engagement, disengagement, and sensitivity bias in individuals suffering from pathological worry. Twenty participants high in worry proneness and 16 control participants low in worry proneness completed an emotional go/no-go task with worry-related threat words and neutral words. Shorter reaction times (i.e., threat engagement bias), smaller omission error rates (i.e., threat sensitivity bias), and larger commission error rates (i.e., threat disengagement bias) emerged only in the high worry group when worry-related words constituted the go-stimuli and neutral words the no-go stimuli. Also, smaller omission error rates as well as larger commission error rates were observed in the high worry group relative to the low worry group when worry-related go stimuli and neutral no-go stimuli were used. The obtained results await further replication within a generalized anxiety disorder sample. Also, further samples should include men as well. Our data suggest that worry-prone individuals are threat-sensitive, engage more rapidly with aversion, and disengage harder. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The Strategic Arms Reduction Treaty (START I), a seminal arms control agreement that substantially reduced the levels of deployed strategic nuclear arms in the United States and Russia, will expire in December 2009. At this time, it is unclear what - if anything - will replace it. While the treaty remains relevant, more than a simple extension is appropriate. Instead the authors advocate for a successor regime that builds on the START I legacy but does not rely on the traditional tools of arms control. This paper examines the strategic context in which a successor regime would be developed and proposes several recommendations for future action

    Although a great deal of literature has been dedicated to the mutual links between emotion and the selective attention component of executive control, there is very little data regarding the links between emotion and the inhibitory component of executive control. In the current study we employed an emotional stop-signal task in order to examine whether emotion modulates and is modulated by inhibitory control. Results replicated previous findings showing reduced inhibitory control [longer stop-signal reaction time (SSRT)] following negative, compared to neutral pictures. Most importantly, results show decreased emotional interference following stop-signal trials. These results show that the inhibitory control component of executive control can serve to decrease emotional effects. We suggest that inhibitory control and emotion have a two-way connection in which emotion disrupts inhibitory control and activation of inhibitory control disrupts emotion.

Results replicated previous findings showing reduced inhibitory control (longer stop-signal reaction time following negative, compared to neutral pictures. Most importantly, results show decreased emotional interference following stop-signal trials. These results show that the inhibitory control component of executive control can serve to decrease emotional effects. We suggest that inhibitory control and emotion have a two-way connection in which emotion disrupts inhibitory control and activation of inhibitory control disrupts emotion.

  4. Stopping-power ratios for dosimetry

    The determination of the absorbed dose at a specified location in a medium irradiated with an electron or photon beam normally consists of two steps: (1) the determination of the mean absorbed dose to a detector by using a calibration factor or performing an absolute measurement, (2) the determination of the absorbed dose to the medium at the point of interest by calculations based on the knowledge of the absorbed dose to the detector and the different stopping and scattering properties of the medium and the detector material. When the influence of the detector is so small that the electron fluence in the medium is not modified, the ratio of the mass collision stopping power of the two materials accounts for the differences in energy deposition, and provides a conversion factor to relate the absorbed dose in both materials. Today, all national and international dosimetry protocols and codes of practice are based on such procedures, and the user easily can carry out these steps using tabulated data to convert a measured quantity to absorbed dose in the irradiated medium at the location of interest. Effects due to the spatial extension of the detector are taken into account using perturbation correction factors. The Monte Carlo method has become the most common and powerful calculational technique for determining the electron fluence (energy spectra) under different irradiation conditions. Cavity theory is then used to calculate stopping-power ratios. In this chapter, the different steps needed to evaluate s-ratios will be considered, emphasizing the different types of cavity-theory integrals and the Monte Carlo techniques used to derive the necessary electron spectra in the range of energies commonly used in radiation dosimetry, i.e., photon and electron beams with energies up to 50 MeV

    An approach to exemplar based recognition of visual shapes is presented. The shape information is described by attributed interest points (keys) detected by an end-stop operator. The attributes describe the statistics of lines and edges local to the interest point, the position of neighboring int...... interest points, and (in the training phase) a list of recognition names. Recognition is made by a simple voting procedure. Preliminary experiments indicate that the recognition is robust to noise, small deformations, background clutter and partial occlusion....

  6. Jojoba could stop the desert creep

    The Sahara desert is estimated to be expanding at a rate of 5km a year. The Sudanese government is experimenting with jojoba in six different regions as the bush has the potential to stop this ''desert creep''. The plant, a native to Mexico, is long known for its resistance to drought and for the versatile liquid wax that can be extracted from its seeds. It is estimated that one hectare of mature plants could produce 3000 kg of oil, currently selling at $50 per litre, and so earn valuable foreign currency.

    This paper addresses the problem of generalization error estimation in neural networks. A new early stop criterion based on a Bootstrap estimate of the generalization error is suggested. The estimate does not require the network to be trained to the minimum of the cost function, as required...... by other methods based on asymptotic theory. Moreover, in contrast to methods based on cross-validation which require data left out for testing, and thus biasing the estimate, the Bootstrap technique does not have this disadvantage. The potential of the suggested technique is demonstrated on various time...

    The efficiency of a nonlinear optical process is proportional to the interaction time. We report a scheme of all-optical switching based on two motionless light pulses via the effect of electromagnetically induced transparency. One pulse was stopped as the stationary light pulse (SLP) and the other was stopped as stored light. The time of their interaction via the medium can be prolonged and, hence, the optical nonlinearity is greatly enhanced. Using a large optical density (OD) of 190, we achieved a very long interaction time of 6.9 μs. This can be analogous to the scheme of trapping light pulses by an optical cavity with a Q factor of 8×10{sup 9}. With the approach of using moving light pulses in the best situation, a switch can only be activated at 2 photons per atomic absorption cross section. With the approach of employing a SLP and a stored light pulse, a switch at only 0.56 photons was achieved and the efficiency is significantly improved. Moreover, the simulation results are in good agreement with the experimental data and show that the efficiency can be further improved by increasing the OD of the medium. Our work advances the technology in quantum information manipulation utilizing photons.

  11. Seismic stops vs. snubbers, a reliable alternative

    1988-01-01

    The Seismic Stops methodology has been developed to provide a reliable alternative for providing seismic support to nuclear power plant piping. The concept is based on using rigid passive supports with large clearances. These gaps permit unrestrained thermal expansion while limiting excessive seismic displacements. This type of restraint has performed successfully in fossil fueled power plants. A simplified production analysis tool has been developed which evaluates the nonlinear piping response including the effect of the gapped supports. The methodology utilizes the response spectrum approach and has been incorporated into a piping analysis computer program RLCA-GAP. Full scale shake table tests of piping specimens were performed to provide test correlation with the developed methodology. Analyses using RLCA-GAP were in good agreement with test results. A sample piping system was evaluated using the Seismic Stops methodology to replace the existing snubbers with passive gapped supports. To provide further correlation data, the sample system was also evaluated using nonlinear time history analysis. The correlation comparisons showed RLCA-GAP to be a viable methodology and a reliable alternative for snubber optimization and elimination. (orig.)

  12. Contrast effects on stop consonant identification.

    Changes in the identification of speech sounds following selective adaptation are usually attributed to a reduction in sensitivity of auditory feature detectors. An alternative explanation of these effects is based on the notion of response contrast. In several experiments, subjects identified the initial segment of synthetic consonant-vowel syllables as either the voiced stop [b] or the voiceless stop [ph]. Each test syllable had a value of voice onset time (VOT) that placed it near the English voiced-voiceless boundary. When the test syllables were preceded by a single clear [b] (VOT = -100 msec), subjects tended to identify them as [ph], whereas when they were preceded by an unambiguous [ph] (VOT = 100 msec), the syllables were predominantly labeled [b]. This contrast effect occurred even when the contextual stimuli were velar and the test stimuli were bilabial, which suggests a featural rather than a phonemic basis for the effect. To discount the possibility that these might be instances of single-trial sensory adaptation, we conducted a similar experiment in which the contextual stimuli followed the test items. Reliable contrast effects were still obtained. In view of these results, it appears likely that response contrast accounts for at least some component of the adaptation effects reported in the literature.

    Full Text Available PURPOSE: To evaluate the performance of a 'one-stop' clinic in terms of proportion of discharges or inclusion in surgical waiting lists. MATERIALS AND METHODS: All patients were referred from primary care facilities (population 220.646 and from different departments in the hospital. Eight senior urologists, two registered nurses and two nurse attendants participated in the experience. Prior to the start of the project, referral protocols had been agreed with the primary care physicians involved. Compliance with the protocols was periodically tested. Eventually 5537 first visits (January-December 2009 where evaluable. RESULTS: Overall, the 'one-stop' format proved feasible in 74.2% of the patients (4108/5537. Patients, who successfully used the 'one-stop' format, were significantly younger than those who required additional consultations (43 vs 50 years old, respectively, Student's t test < 0.001. For obvious reasons the 'one-stop' format was universally possible in male sterilization and penile phimosis patients. Similarly, the 'one-stop' policy was applied in most consultations due to male sexual dysfunction (75% and urinary tract infection (73%. Other health problems, such as haematuria (62% and renal colic (46%, required more than one visit so that care of the patient reverted to the traditional, outpatient care model. CONCLUSION: A 'one-stop' philosophy is feasible for a number of procedures in a urological outpatient clinic. The costs to implement such an approach would be limited to managerial expenditure.

    Full Text Available Abstract Background Our approach to advancing the treatment of psychosis is to focus on key single symptoms and develop interventions that target the mechanisms that maintain them. In our theoretical research we have found worry to be an important factor in the development and maintenance of persecutory delusions. Worry brings implausible ideas to mind, keeps them there, and makes the experience distressing. Therefore the aim of the trial is to test the clinical efficacy of a cognitive-behavioral intervention for worry for patients with persecutory delusions and determine how the worry treatment might reduce delusions. Methods/Design An explanatory randomized controlled trial - called the Worry Intervention Trial (WIT - with 150 patients with persecutory delusions will be carried out. Patients will be randomized to the worry intervention in addition to standard care or to standard care. Randomization will be carried out independently, assessments carried out single-blind, and therapy competence and adherence monitored. The study population will be individuals with persecutory delusions and worry in the context of a schizophrenia spectrum diagnosis. They will not have responded adequately to previous treatment. The intervention is a six-session cognitive-behavioral treatment provided over eight weeks. The control condition will be treatment as usual, which is typically antipsychotic medication and regular appointments. The principal hypotheses are that a worry intervention will reduce levels of worry and that it will also reduce the persecutory delusions. Assessments will be carried out at 0 weeks (baseline, 8 weeks (post treatment and 24 weeks (follow-up. The statistical analysis strategy will follow the intention-to-treat principle and involve the use of linear mixed models to evaluate and estimate the relevant between- and within-subjects effects (allowing for the possibility of missing data.

    Anxious apprehension/worry is associated with exaggerated error monitoring; however, the precise mechanisms underlying this relationship remain unclear. The current study tested the hypothesis that the worry-error monitoring relationship involves left-lateralized linguistic brain activity by examining the relationship between worry and error monitoring, indexed by the error-related negativity (ERN), as a function of hand of error (Experiment 1) and stimulus orientation (Experiment 2). Results revealed that worry was exclusively related to the ERN on right-handed errors committed by the linguistically dominant left hemisphere. Moreover, the right-hand ERN-worry relationship emerged only when stimuli were presented horizontally (known to activate verbal processes) but not vertically. Together, these findings suggest that the worry-ERN relationship involves left hemisphere verbal processing, elucidating a potential mechanism to explain error monitoring abnormalities in anxiety. Implications for theory and practice are discussed. © 2015 Society for Psychophysiological Research.

    Anxiety has been linked to onset of cardiovascular disease. This study examines the differential impact of types of anxiety (panic, phobia and worry) on 3-year onset of non-fatal cardiovascular disease (CVD). By investigating anxiety disorders as opposed to anxiety symptoms and by using a reliable diagnostic instrument to assess anxiety, limitations of previous studies are considered. 5149 persons at risk for CVD were interviewed using the Composite International Diagnostic Interview. The panic-type included panic disorder and panic attacks; the phobic-type included agoraphobia and social phobia, and the worry-type included generalized anxiety disorder. CVD was self-reported and required treatment or monitoring by a doctor. Analyses were adjusted for sociodemographics, behavioral variables, and comorbid somatic and psychiatric disorders. During follow-up, 62 persons (1.2%) developed CVD. Baseline generalized anxiety disorder was strongly associated with onset of CVD (adjusted OR: 3.39). Further research should replicate findings and focus on biological underpinnings of this association. Copyright © 2014 Elsevier Ltd. All rights reserved.

    There is currently scant research on the role of transport priorities, risk perception and worry for travel mode use and preferences. The present study aims to examine these factors in relation to mode use and preferences among Norwegian commuters. A web-based survey was conducted in a randomly obtained representative sample of daily commuters in the extended greater Oslo area (n=690). The results showed that those who prioritized efficiency and flexibility tended to commute by car, while those who prioritized safety and comfort used public (e.g. metro, tram, and train) or active (e.g. walking and cycling) transport. In a free choice scenario, the respondents who prioritized flexibility reported a preference for using a car, whereas those who prioritized safety and comfort preferred public and active transport for their commuter travels. Risk perception of high impact events, such as terrorism and major accidents, as well as risk perception related to personal impact risks (theft, violence etc.) were related to car use on commuter travels. Transport-related worry exerted weak influences on mode use and preferences. Increased speed on rail transport and more frequent departures may be effective in reducing car use on commuter travels. Risk communication should focus on highlighting the low risk of experiencing security and safety issues in the public transport sector, and this message should be complemented by efforts to reduce the probability of negative events affecting public transport.

    Full Text Available This ex post facto study aimed to replicate previous research demonstrating an association between generalized anxiety disorder (GAD and irritable bowel syndrome (IBS and to extend this work by examining possible relationships between IBS and psychological constructs associated with the development of GAD. A total of 391 undergraduate psychology students completed self-report diagnostic measures of IBS and GAD as well as questionnaire measures of trait anxiety, worry, experiential avoidance, intolerance of uncertainty, and problem-solving confidence. Consistent with previous research, an association between IBS and GAD was found. Compared to participants without IBS, participants endorsing Rome II diagnostic criteria for IBS reported greater trait anxiety, worry, and experiential avoidance. No group differences on measures of intolerance of uncertainty and problem-solving confidence were found. Etiological factors considered specific to the development of GAD (i.e., increased intolerance of uncertainty and deficits in problem-solving confidence do not account for the observed relationships between IBS and general anxiety variables. However, experiential avoidance, or attempts to avoid unwanted bodily sensations, emotions, or other internal events, does appear elevated among IBS individuals. Implications of these findings are discussed within the context of a biopsychosocial model of IBS.

    Quit rates are lower and relapse rates are higher for people in close relationships with a partner who smokes. Although desire to quit is often related to health concerns for one's self, much less is known about psychosocial factors associated with quitting in dual-smoker couples. This study investigated relations among beliefs about smoking and desire to quit from both partners' perspectives. We recruited 63 couples in which both partners smoke daily. Participants were aged 21-67 (M = 43.0, SD = 11.3) and had been smoking for 4-51 years (M = 22.9, SD = 11.3). Individuals' desire to quit related to worry about partner's health (r = .29, p belief that own smoking has caused partner physical harm (r = .38, p harm of smoking for oneself (r = .30, p scale) for their partner's help if they attempt to quit. Dual-smoker couples are at heightened health risks due to exposure to passive smoke and their own smoking. Partners' perceived risk and worry about the harms of smoking could be important leverage points for smoking cessation efforts. Interventions can be informed by considering both partners' beliefs and by helping partners develop plans for quitting and supporting each other.

    This paper presents qualitative findings on the principal worries, concerns and dangers surrounding risk perception extracted from the Cross-cultural Survey carried out within RISKPERCOM' research project (Risk Perception and Communication). A questionnaire was mailed to a random sample of the Spanish population allowing a study of amplification/attenuation with regard to the tenth anniversary as well as investigating management and communication issues related to radiological matters. The questionnaires were mailed to the adult population from 18 to 75 years of age, where 48.9% males and 51.1 % females. The number of questionnaires obtained for each wave were 490. The response rate was around 69%. At this paper we present the principal concerns, worries and dangers perceived by the Spanish population as identified through three open questions. The items were grouped in different categories; national political situation, economical concern, personal/social concerns, environmental concerns, global concerns... These categories are associated through correspondence analysis to socio-demographical variables as sex, age, education, political orientation an environmental attitude. (authors)

    Modern health worries (MHWs) were related to somatic symptoms and to preference of holistic healing methods in previous studies. The study aimed to investigate the contribution of symptom-related and holism-related factors to MHWs. Participants (visitors of an Internet news portal; N = 16152; 64.1 % males) completed a questionnaire assessing MHWs, somatosensory amplification, somatic symptoms, positive and negative affect, spirituality, holistic health beliefs, and various aspects of health care utilization (both conventional and alternative). Exploratory factor analysis with oblique rotation revealed two independent dimensions ("Somatic symptom distress" and "Holism") MHWs were involved with factor loadings of 0.294 and 0.417, respectively. The existence of two factors was supported by the results of confirmatory factor analysis. No practically significant interaction between the two factors was found in binary logistic regression analysis. Positive and negative affect, somatosensory amplification, spirituality, and holistic health beliefs were positively connected, while self-rated health status was negatively connected to MHWs even after controlling for socio-demographic and treatment-related variables. Holistic thinking and symptom-related behavioral and psychological factors are independently associated with MHWs. Modern health worries can be conceptualized as symptom-related by-products of a holistic-spiritual worldview.

    Using the stress-coping framework, this study examined whether worry about not having a caregiver in old age was associated with depressive symptoms among widowed Chinese older adults, including the moderating effects of self-perceived family support. Using a sample of 5331 widowed adults aged 60 years old or older from the 2006 National Sample Survey of the Aged Population in Urban/Rural China, we regressed measures of depressive symptoms on worry about not having a caregiver. We also tested moderation effects of family support. Individuals who were worried about not having a caregiver reported significantly higher levels of depressive symptoms. Feeling that their children are filial, having instrumental support from children, and having only daughters moderated the effects of worry about not having a caregiver on depressive symptoms. Our findings indicate the detrimental effects of worry about not having a caregiver on the psychological well-being of widowed older adults. This study also highlights some forms of family support that may help reduce such negative effects of widowhood.

    Full Text Available Mindfulness-based interventions have recently been proposed for the treatment of generalized anxiety disorder (GAD. However, the specific nature of the relationship between mindfulness skills and pathological worry is still not very well known. This study analyzes the mediating role of psychological inflexibility-a central construct in the acceptance and commitment therapy (ACT model of psychopathology-in the effect of mindfulness skills on pathological worry. A total of 132 nonclinical participants completed questionnaires assessing the constructs of interest: the Penn State Worry Questionnaire (PSWQ, the Acceptance and Action Questionnaire - II (AAQ-II, and the Kentucky Inventory of Mindfulness Skills (KIMS. Because the Spanish translation of the KIMS used lacked of a formal validation, its psychometric properties and factor structure were previously evaluated. This process led to a reduced version of the KIMS that showed good internal consistency and factor structure. Mediation analyses revealed that psychological inflexibility fully mediated the effects of mindfulness skills as a set on pathological worry. Regarding specific mindfulness skills, psychological inflexibility was shown to be a mediator and suppressor, respectively, of the relationship between acceptance without judgment and act with awareness on worry. Results are discussed emphasizing the need of using mindfulness exercises to promote psychological flexibility.

    The Emergency Diesel Generator (EDG) was being tested after overhaul maintenance. While the EDG was running at the rated speed (450 rpm), an operator pressed the manual stop button. But the EDG failed to stop and unintentionally started again. After the unintentional re-start, the EDG maintained running speed of 340 rpm. In the category of a governing system, this paper analyzes the cause of unintentional restart of the EDG that unintentionally re-started and maintained a speed at 340 rpm. The results of the analysis were then verified by a test run. Finally, we identified a correlation between fuel rack sticking and unintentional re-starting of the EDG. An analysis was conducted to confirm the cause of an EDG which was unintentionally restarting and running at 340rpm (rated speed is 450 rpm). Through a test run, it was confirmed that the results of the analysis are correct. The cause of the EDG unintentionally restarting was that it still rotated at 55 rpm over the minimum starting speed at the moment when the shutdown cylinder stopped blocking the fuel, because of a stuck fuel rack at the R7 cylinder. At the same time, the fuel that had been supplied into the cylinders (combustion chamber) by the governing system exploded and the EDG restarted unintentionally.

    1983-01-01

    Review is made for the study on the power for stopping heavy ions. The studies on the power for stopping heavy ions passing through materials have been developed in the last twenty years due to the accuracy improvement in the data analysis of the power for stopping light ions, the requirement of data establishment on the power for stopping heavy ions from fusion research and the development of the experimental studies by heavy-ion accelerators. The relation between the analysis of the power for stopping heavy ions and the power for stopping light ions is described from the standpoint that the results on the power for stopping light ions serve as the guide for the study on the power for stopping heavy ions. Both at present and in future. The analysis of stopping power data with the accuracy from +-10 to 20 % is possible from the theoretical analysis of effective electric charge and its systematic table of the numerical data. The outline of the scaling rule on effective electric charge is discussed. The deviation of the experimental data from the scaling rule is discussed by comparing with the measured values of effective electric charge ratio. Various analyses of the power for stopping heavy ions are summarized. (Asami, T.)

    2014-09-01

    Full Text Available The purpose of this paper is to discuss Intelligent Bus Stops in a special Demand Responsive Transit (DRT, the Flexible Bus System. These Intelligent Bus Stops are more efficient and information rich than Traditional Bus Stops. The real time synchronization of the Flexible Bus System makes it unique as compared to Traditional Bus Systems. The Main concern is to make Bus Stops intelligent and information rich. Buses are informed about the no. of passengers waiting at the upcoming Bus Stops. If there are no passengers to ride or get off on upcoming Bus Stop, the Bus can skip that Bus Stop and head towards the next Bus Stop where passenger is waiting, which will decrease the ride time of the passengers on the Bus and also the wait time of the passengers waiting on the upcoming Bus Stops. Providing more information at Bus Stops about the Destination (Time to Destination, Distance to Destination etc. and Buses (Bus Location, Arrival Time of Bus etc. makes it easier for the passengers to decide whether to ride a particular Bus or not.

    To determine the predictive value of individual and combined dutch-early-nurse-worry-indicator-score indicators at various Early Warning Score levels, differentiating between Early Warning Scores reaching the trigger threshold to call a rapid response team and Early Warning Score levels not reaching this point. Dutch-early-nurse-worry-indicator-score comprises nine indicators underlying nurses' 'worry' about a patient's condition. All indicators independently show significant association with unplanned intensive care/high dependency unit admission or unexpected mortality. Prediction of this outcome improved by adding the dutch-early-nurse-worry-indicator-score indicators to an Early Warning Score based on vital signs. An observational cohort study was conducted on three surgical wards in a tertiary university-affiliated teaching hospital. Included were surgical, native-speaking, adult patients. Nurses scored presence of 'worry' and/or dutch-early-nurse-worry-indicator-score indicators every shift or when worried. Vital signs were measured according to the prevailing protocol. Unplanned intensive care/high dependency unit admission or unexpected mortality was the composite endpoint. Percentages of 'worry' and dutch-early-nurse-worry-indicator-score indicators were calculated at various Early Warning Score levels in control and event groups. Entering all dutch-early-nurse-worry-indicator-score indicators in a multiple logistic regression analysis, we calculated a weighted score and calculated sensitivity, specificity, positive predicted value and negative predicted value for each possible total score. In 3522 patients, 102 (2·9%) had an unplanned intensive care/high dependency unit admissions (n = 97) or unexpected mortality (n = 5). Patients with such events and only slightly changed vital signs had significantly higher percentages of 'worry' and dutch-early-nurse-worry-indicator-score indicators expressed than patients in the control group.

    This paper presents data and information on the end of the life of nuclear reactors. One deals more particularly with installations of industrialized countries. This report gives the motivations which have involved the definitive shut down of nuclear power plants and of research reactors in the concerned countries. A schedule of definitive reactor shutdowns is presented. Then, one deals with nuclear power plants of which the construction has been stopped. The reasons of these situations are also given. The temporary difficulties met during the construction or the starting of nuclear power plants these last years are mentioned. Most times, there are economical or political considerations, or safety reasons. Finally, the nuclear power plants stopped for more than two years are mentioned [fr

    A clinical trial using remune, the anti-HIV vaccine developed by the late Dr. Jonas Salk, has been ended. The study is a clinical-endpoint trial which looks for statistically significant differences in AIDS sickness or death between patients who add remune to their treatment regimens versus those who use a placebo. Agouron Pharmaceuticals and the Immune Response Corporation who were conducting the trial announced their decision to stop it after an analysis by the Data Safety Monitoring Board. No differences in clinical endpoints were found and it was projected that continuing the trial would likely not find any. The companies are now planning two new Phase III trials using viral load testing rather than clinical endpoints as study criteria.

  17. Stop Lepton Associated Production at Hadron Colliders

    2003-01-01

    At hadron colliders, the search for R-parity violating supersymmetry can probe scalar masses beyond what is covered by pair production processes. We evaluate the next-to-leading order SUSY-QCD corrections to the associated stop or sbottom production with a lepton through R-parity violating interactions. We show that higher order corrections render the theoretical predictions more stable with respect to variations of the renormalization and factorization scales and that the total cross section is enhanced by a factor up to 70% at the Tevatron and 50% at the LHC. We investigate in detail how the heavy supersymmetric states decouple from the next-to-leading order process, which gives rise to a theory with an additional scalar leptoquark. In this scenario the inclusion of higher order QCD corrections increases the Tevatron reach on leptoquark masses by up to 40 GeV and the LHC reach by up to 200 GeV.

    Full Text Available The stop-band filter with the new band-rejection element is proposed. The element is a coaxial waveguide with the slot in the centre conductor. In the frame of this research, the numerical and experimental investigations of the amplitude-frequency characteristics of the filter are carried out. It is noted that according to the slot parameters the two typical resonances (half-wave and quarter-wave can be excited. The rejection band of the single element is defined by the width, depth, and dielectric filling of the slot. Fifth-order Chebyshev filter utilizing the aforementioned element is also synthesized, manufactured, and tested. The measured and simulated results are in good agreement. The experimental filter prototype exhibits the rejection band 0.86 GHz at the level −40 dB.

    Since the discovery of the genetic code and protein translation mechanisms (1), a limited number of variations of the standard assignment between unique base triplets (codons) and their encoded amino acids and translational stop signals have been found in bacteria and phages (2-3). Given the apparent ubiquity of the canonical genetic code, the design of genomically recoded organisms with non-canonical codes has been suggested as a means to prevent horizontal gene transfer between laboratory and environmental organisms (4). It is also predicted that genomically recoded organisms are immune to infection by viruses, under the assumption that phages and their hosts must share a common genetic code (5). This paradigm is supported by the observation of increased resistance of genomically recoded bacteria to phages with a canonical code (4). Despite these assumptions and accompanying lines of evidence, it remains unclear whether differential and non-canonical codon usage represents an absolute barrier to phage infection and genetic exchange between organisms. Our knowledge of the diversity of genetic codes and their use by viruses and their hosts is primarily derived from the analysis of cultivated organisms. Advances in single-cell sequencing and metagenome assembly technologies have enabled the reconstruction of genomes of uncultivated bacterial and archaeal lineages (6). These initial findings suggest that large scale systematic studies of uncultivated microorganisms and viruses may reveal the extent and modes of divergence from the canonical genetic code operating in nature. To explore alternative genetic codes, we carried out a systematic analysis of stop codon reassignments from the canonical TAG amber, TGA opal, and TAA ochre codons in assembled metagenomes from environmental and host-associated samples, single-cell genomes of uncultivated bacteria and archaea, and a collection of phage sequences

  1. The interpretation of low mood and worry by high users of secondary care with medically unexplained symptoms

    2011-10-01

    Full Text Available Abstract Background Around 1% of adults are repeatedly referred from primary to secondary care with medically unexplained symptoms (MUS; many of these patients have depression and anxiety disorders which are unrecognized or inadequately treated. We aimed to investigate the ways patients with MUS and their General Practitioners (GPs interpret low mood and worry, whether they regard them as depressive or anxiety disorders and how they relate them causally to symptoms. Methods We carried out semi-structured interviews with 27 patients who had been repeatedly referred to specialists for MUS and their GPs and analysed transcripts by qualitative comparison. The analysis examined themes relating to low mood and worry, and their influence on symptoms. It drew on the concept of "otherness", whereby mental phenomena can be located either within the self or as separate entities. Results Both patients and GPs acknowledged the presence of low mood and worry. They viewed low mood as either an individual's personal response to circumstances (including their physical symptoms or as the illness called "depression"; only the latter was amenable to medical intervention. Worry was seen as a trait rather than as a symptom of an anxiety disorder. While low mood and worry were acknowledged to influence physical symptoms, they were considered insufficient to be the main cause by either the patients or their doctors. Conclusions Patients with MUS who are high users of secondary care services interpret low mood and worry in ways which allow them to be discussed with professionals, but not as the cause of their physical symptoms.

  2. The impact of intolerance of uncertainty, worry and irritability on quality of life in persons with epilepsy: irritability as mediator.

    Epilepsy is a neurological disorder afflicting many people in the world. The impact of epilepsy on the quality of life of those afflicted with epilepsy is greater than the limitations imposed by the seizures alone. Among the several psychological disorders found to be comorbid with epilepsy are anxiety and depression, both of which impair quality of life in epilepsy. Some studies have reported that the anxiety seen in epilepsy is characterized by worry while the depression seen is characterized by irritability. A concept common to both anxiety and depression is intolerance of uncertainty. Therefore, the study explores the relationship between intolerance of uncertainty, worry and irritability and their association to quality of life in epilepsy. A descriptive-correlational research method was used and the research sample comprised 60 consecutive referrals seeking outpatient neurological services for epilepsy at Alavi Hospital in Ardebil. Data were collected by administering the Penn State Worry Questionnaire, Intolerance of Uncertainty Scale, Irritability Questionnaire and Quality of Life in Epilepsy Inventory. Data were analyzed using Pearson's correlation coefficients and multivariate regression analysis. Mediation and moderation analyses were conducted. Findings indicated that intolerance of uncertainty, worry and irritability have unique significant effects on quality of life. The implications are that interventions aimed at improving the quality of life of patients with epilepsy should address their feelings of uncertainty, worry and irritability. Furthermore, irritability seems to mediate the impact of both intolerance of uncertainty and worry on quality of life of individuals with epilepsy. No significant moderation effects were noted. Results underscore the important role of irritability in the quality of life of persons with epilepsy. The findings are discussed with reference to the possibility of particular predisposing temperaments and add credence to

    In recent years, there have been dramatic increases in medical imaging use and increasing media attention to increased exposure to ionizing radiation in the United States. Patient perspectives on medical imaging radiation (MIR) use is understudied, but could guide primary care discussions. This study examines prevalence of worry about the health harms from MIR in the US general population. This cross-sectional study used the 2012-2013 Health Information National Trends Survey conducted by the National Cancer Institute. A nationally representative sample (N = 3532) was drawn from the US general population to observe prevalence of worry about MIR as well as potential covariates, including demographic, medical, and psychological factors, health information-seeking, physician trust in providing cancer information, and cancer fatalism. About 65% of the sample population reported experiencing at least some worry about MIR. Univariable and multivariable logistic regressions indicate higher rates of MIR worry among women, racial/ethnic minorities, those with lower educational attainment, foreign-born Americans, those who self-report poorer health, and those with a personal history of cancer. Lower trust in cancer information from physicians and greater attention to cancer information from popular media were each associated with higher rates of worry about health harms of MIR. An accurate assessment of public worry about MIR will aid primary care providers' efforts to understand patient responses to medical imaging and identify addressable knowledge gaps regarding benefits and risks of medical imaging. These data may improve risk communication regarding medical imaging among referring primary care physicians, radiologists, and patients. © The Author(s) 2016.

  5. Design of permanent block stopping to resist strata convergence

    Energy Technology Data Exchange (ETDEWEB)

    Ray, R.E.

    1985-11-01

    Conventional concrete block plastered with a cementitious coating is the most common material used in the construction of permanent stoppings to direct airflow in underground mines in the US. All mines experience various degrees of strata convergence depending on depth of overburden, geological conditions, and type of roof support employed. Strata convergence will cause cracks and joint openings in masonry stoppings, resulting in significant air leakage losses. Where strata convergence is severe, complete structural failure of the stopping can ultimately occur. Reconstruction of damaged or destroyed stoppings adds expensive overheads to mining operations, and even greater expenses are incurred from the additional fan horsepower required to overcome leakage losses. Ideally, a stopping should maintain high resistance to airflow while yielding to strata convergence. By properly incorporating a polyisocyanurate rigid foam material within the masonry block structure, stopping service life can be increased in mines experiencing strata convergence problems such as floor heave, roof loading, and lateral rib movement.

    2014-09-01

    The American Academy of Pediatrics recognizes insufficient sleep in adolescents as an important public health issue that significantly affects the health and safety, as well as the academic success, of our nation's middle and high school students. Although a number of factors, including biological changes in sleep associated with puberty, lifestyle choices, and academic demands, negatively affect middle and high school students' ability to obtain sufficient sleep, the evidence strongly implicates earlier school start times (ie, before 8:30 am) as a key modifiable contributor to insufficient sleep, as well as circadian rhythm disruption, in this population. Furthermore, a substantial body of research has now demonstrated that delaying school start times is an effective countermeasure to chronic sleep loss and has a wide range of potential benefits to students with regard to physical and mental health, safety, and academic achievement. The American Academy of Pediatrics strongly supports the efforts of school districts to optimize sleep in students and urges high schools and middle schools to aim for start times that allow students the opportunity to achieve optimal levels of sleep (8.5-9.5 hours) and to improve physical (eg, reduced obesity risk) and mental (eg, lower rates of depression) health, safety (eg, drowsy driving crashes), academic performance, and quality of life.

    In order to assure the accuracy of the numerical solution of the iterative method for solving PDE (partial differential equation), the stopping test is very important. If the coefficient matrix of the system of linear algebraic equations is strictly diagonal dominant or irreducible weakly diagonal dominant, the stopping test formulas of the iterative method for solving PDE is proposed. Several numerical examples are given to illustrate the applications of the stopping test formulas

    To disentangle the complex associations of depression and anxiety with mild cognitive impairment (MCI) at the population level. We examined subgroups of anxiety symptoms and depression symptom profiles in relation to MCI, which we defined using both cognitive and functional approaches. We used an epidemiologic, cross-sectional study with an age-stratified, random, population-based sample of 1,982 individuals aged 65 years and over. Three definitions of MCI were used: 1) a purely cognitive classification into amnestic and nonamnestic MCI, 2) a combined cognitive-functional definition by International Working Group (IWG) criteria, and 3) a purely functional definition by the Clinical Dementia Rating (CDR) of 0.5. Three depression profiles were identified by factor analysis of the modified Center for Epidemiological Studies-Depression Scale: core mood, self-esteem/interpersonal, and apathy/neurovegetative profiles. Three anxiety groups, chronic mild worry, chronic severe anxiety, and recent-onset anxiety, were based on screening questions. Recent-onset anxiety was associated with MCI by nonamnestic and IWG criteria, chronic severe anxiety was associated with MCI by all definitions, and chronic mild worry was associated with none. Of the depression profiles, the core mood profile was associated with CDR-defined MCI, the apathy/neurovegetative profile was associated with MCI by amnestic, IWG, and CDR definitions, and the self-esteem/interpersonal profile was associated with none. In this population-based sample, subgroups with different anxiety and depression profiles had different relationships with cognitive and functional definitions of MCI. Anxiety, depression, and MCI are all multidimensional entities, interacting in complex ways that may shed light on underlying neural mechanisms.

    Statins could have physiologic properties that may beneift patients that have been diagnosed with various acute neurological diseases. This review aims tosummarize the literature pertaining to stain use in acute neurological disease such as subarachnoid hemorrhage, intracerebral hemorrhage (ICH), cerebral ischemia (CI), traumatic brain injury, status epilepticus and meningitis. The authors reviewed published abstracts and manuscripts pertaining to experimental and clinical trials relevant to statins in acute neurological disease. Although acute statin therapy in the setting of subarachnoid hemorrhage might reduce delayed cerebral ischemia and mortality, it should not be considered standard care at this time. Acute statins therapy has not demonstrated anybeneift yet folowing an ICH or CI. Acute statin withdrawal may worsen outcome in acute CI. Observational and case-control studies suggest that pretreatment with statin at time of onset may be associated with better outcomes. Even though preclinical studies have shown statins to have beneifcial effects, there has been no clinical evidence. In conclusion, current published studies have not shown that acute statin therapy has any beneifcal effects in acute neurologic diseases and therefore further large randomized clinical trials are needed.

    Implementing a comprehensive approach to decreasing tobacco use in a large health plan requires hard work and commitment on the part of many individuals. We found that major organisational change can be accomplished and sustained. Keys to our success included our decision to remove access barriers to our cessation programmes (including cost); obtaining top leadership buy-in; identifying accountable individuals who owned responsibility for change; measuring key processes and outcomes; and finally keeping at it tenaciously through multiple cycles of improvement.

    Because the clinical nurse specialist (CNS) role has been changed or eliminated in many hospital organizations, many CNSs in career transition are considering establishing collaborative or independent nursing consultation practices. Opportunities for consultants exist in diverse practice settings and specialties. Before starting a consultation practice, the CNS should carefully examine goals, identify resources, and begin contacting potential referral sources. He or she must also decide what form of business organization to establish and write a business plan to solidify ideas and prepare for the unexpected. Most CNS consultants rely on personal savings to cover initial business and personal expenses, and many continue working as a CNS until the consultation practice is established. Fees can be set based on community standards, what the market will bear, desired projected income, or a third-party payor's fee schedule. The consultation practice can be marketed by word of mouth, inexpensive advertising techniques such as distributing flyers and business cards, direct mall, and media advertising. In today's healthcare marketplace, opportunities abound for the CNS risk-taker interested in starting a nursing consultation practice.

    The first major particle physics summer conference has just started this week in Grenoble. After the Quark-Matter conference, the Europhysics Conference on High-Energy Physics marks the start of a promising harvest for the LHC experiments.   For the first time, the collaborations will be presenting their latest results based on all luminosity taken until end of June, which will provide more precise measurements in many areas. Thanks to the excellent performance of the LHC, the experiments have already accumulated a substantial quantity of data allowing them to push back the known limits and refine measurements in many fields ranging from b physics to the search for the Higgs boson and for dark matter. At the time of writing, the LHC collaborations are about to present these new results in an energy range which has never previously been explored. I have congratulated all the teams involved in getting the LHC into operation in record time with great efficiency. Today I would like to acknowledge the...

    Adolescent girls and young women (AGYW) in sub-Saharan Africa have high HIV prevalence and incidence. We sought to understand which HIV risk factors individually and in combination contribute to risk, and whether these factors are associated with HIV worry and risk perception. This study is ongoing at 4 public health centers in Lilongwe, Malawi (2016-2017). AGYW of 15-24 years old were recruited to participate in a study assessing 4 models of service delivery. At each health center, participants completed a baseline survey assessing socioeconomic, behavioral, biomedical, and partnership characteristics; self-reported HIV status; and, if HIV-uninfected, HIV risk perception (high versus low or none) and HIV worry (any versus none). We analyzed associations between baseline characteristics and HIV prevalence, risk perception, and worry. Among 1000 AGYW, median age was 19 years (IQR: 17-21). Thirty-three participants reported being HIV-infected. Fifteen characteristics were associated with HIV infection. Having more risk factors was associated with higher HIV prevalence (≤4 factors, 0.5%; 5-8 factors, 6%; >8 factors, 21%). Having more risk factors was also associated with higher risk perception (P risk factors, 52% did not consider themselves to be at high risk and 21% did not report any HIV worry. Most AGYW perceive little risk of HIV acquisition, even those at highest risk. As a critical gap in the HIV prevention cascade, accurate risk perception is needed to tailor effective and sustained combination prevention strategies for this vulnerable population.

    Limited work has examined worry, or apprehensive anticipation about future negative events, in terms of smoking. One potential explanatory factor is the tendency to respond inflexibly and with avoidance in the presence of smoking-related distress (smoking-specific experiential avoidance). Participants (n = 465) were treatment-seeking daily smokers. Cross-sectional (pre-treatment) self-report data were utilized to assess trait worry, smoking-specific experiential avoidance, and four smoking criterion variables: nicotine dependence, motivational aspects of quitting, perceived barriers to smoking cessation, and severity of problematic symptoms reported in past quit attempts. Trait worry was significantly associated with greater levels of nicotine dependence, motivation to quit smoking, perceived barriers for smoking cessation, and more severe problems while quitting in the past; associations occurred indirectly through higher levels of smoking-specific experiential avoidance. Findings provide initial support for the potential role of smoking-specific experiential avoidance in explaining the association between trait worry and a variety of smoking processes.

    2016-03-01

    Intolerance of uncertainty (IU), negative beliefs about worry (NBW), positive beliefs about worry (PBW), negative problem orientation (NPO) and cognitive avoidance (CA) have been found to be integral in the conceptualisation of Generalised Anxiety Disorder (GAD) in adults, yet they have rarely been investigated in children with GAD. This study sought to determine (a) whether IU, NBW, PBW, NPO and CA differ between children diagnosed with GAD and non-anxious children and (b) to examine whether IU, NBW, PBW, NPO and CA differ between parents of children diagnosed with GAD and parents of children without an anxiety disorder. Participants were 50 children (aged 7-12 years), plus one of their parents. The 25 GAD children and 25 non-anxious children were matched on age and gender. Parents and children completed clinical diagnostic interviews, as well as a battery of questionnaires measuring worry, IU, NBW, PBW, NPO and CA. Children with GAD endorsed significantly higher levels of worry, IU, NBW, NPO and CA, but not PBW compared to non-anxious children. Parents of children with GAD did not differ from parents of non-anxious children on any of the variables. The study was limited by it's use of modified adult measures for some variables and a lack of heterogeneity in the sample. The cognitive variables of IU, NBW, NPO and CA may also be important in the conceptualisation and treatment of GAD in children as they are in adults. Copyright © 2015 Elsevier B.V.

    Objectives Children in families of low socioeconomic status (SES) have been found to have poor sleep, yet the reasons for this finding are unclear. Two possible mediators, presleep worries and home environment conditions, were investigated as indirect pathways between SES and children’s sleep. Participants/Methods The participants consisted of 271 children (M (age) = 11.33 years; standard deviation (SD) = 7.74 months) from families varying in SES as indexed by the income-to-needs ratio. Sleep was assessed with actigraphy (sleep minutes, night waking duration, and variability in sleep schedule) and child self-reported sleep/wake problems (e.g., oversleeping and trouble falling asleep) and sleepiness (e.g., sleeping in class and falling asleep while doing homework). Presleep worries and home environment conditions were assessed with questionnaires. Results Lower SES was associated with more subjective sleep/wake problems and daytime sleepiness, and increased exposure to disruptive sleep conditions and greater presleep worries were mediators of these associations. In addition, environmental conditions served as an intervening variable linking SES to variability in an actigraphy-derived sleep schedule, and, similarly, presleep worry was an intervening variable linking SES to actigraphy-based night waking duration. Across sleep parameters, the model explained 5–29% of variance. Conclusions Sleep environment and psychological factors are associated with socioeconomic disparities, which affect children’s sleep.

    Science.gov (United States)

    McGowan, E; MacAuley, D; Anderson, U

    A one-week smoking awareness initiative and subsequent audit in a general practice are described. All patients attending morning surgery during the study period were offered the opportunity to discuss smoking habits at a smoking awareness clinic: 84 smokers attended. They were interviewed by the practice preventive care nurse who took a smoking history, monitored carbon monoxide (CO Hb) levels and offered a follow-up appointment. CO Hb provided immediate feedback on the effect of smoking and patients who smoked 20 or more cigarettes per day had an average CO Hb of 16.1 per cent. Fifteen per cent of smokers made a commitment to stop smoking and agreed to attend follow-up clinics. A random sample (50) of attenders at the initial Smoking Awareness Clinic (84) were followed up by questionnaire six months later. There were 29 replies (58 per cent); 19 patients (65 per cent) found the visit to the clinic helpful, 14 (48 per cent) reduced the number of cigarettes they smoked, and 11 (38 per cent) altered some other aspect of their lifestyle, of whom four modified their diet and four increased exercise. Five patients claimed they had given up smoking.

  13. Range and stopping power for slow particles

    International Nuclear Information System (INIS)

    Bastiano, M.; Fernandez, J. E.; Molinari, V. G.

    1997-01-01

    Generally, the effects of thermal agitation and chemical bonding of the target atoms need to be taken into account to compute properly the range and stopping power of particles. These two effects, however, complicate very much the calculation of the above parameters, and for this reason are usually neglected. In fact, when the energy of the test particles (t.p.) is sufficiently high compared to the thermal or bonding energies, these two effects can be safely disregarded. When the energy of the t.p. is of the same order of the thermal agitation or the chemical bonding, on the other hand, such approximation is not realistic, and to obtain meaningful results one must take into account the velocity distribution of the field particles (f.p.). The aim of this paper is to present a simple model describing the transport of particles (e.g., electrons) in the thermal zone, considering the thermal agitation of f.p. with an arbitrary distribution. It will be shown that in the first part of the slowing down the kinetic energy of t.p. is partially transformed into temperature. In the second part, the temperature tends to reach the equilibrium temperature, while average velocity of t.p. becomes zero. (author)

    2010-01-01

    After several weeks of hard work, the short technical stop of the LHC accelerator is coming to an end. Following a very intense campaign to repair and retest many thousand high voltage connectors, the upgraded magnet protection system is being commissioned. During this period, the current in the main dipole and quadrupole magnets is carefully increased up to 6kA, required to collide protons at 7TeV centre-of-mass energy. This has been achieved for most of the sectors.   The parameters of the upgraded magnet protection system are accurately calibrated. This operation is needed in order for the magnet protection system to be triggered only when a real problem occurs. The system is now able to detect a transition from superconducting to normal conducting state of the superconducting cable joints between magnets, a necessary condition to operate the magnet system above 2kA. Highly accurate measurements of the joint resistances have been performed by stepping up the current to 5kA. The magnets and the...

  20. Note on measuring electronic stopping of slow ions

    Science.gov (United States)

    Sigmund, P.; Schinner, A.

    2017-11-01

    Extracting stopping cross sections from energy-loss measurements requires careful consideration of the experimental geometry. Standard procedures for separating nuclear from electronic stopping treat electronic energy loss as a friction force, ignoring its dependence on impact parameter. In the present study we find that incorporating this dependence has a major effect on measured stopping cross sections, in particular for light ions at low beam energies. Calculations have been made for transmission geometry, nuclear interactions being quantified by Bohr-Williams theory of multiple scattering on the basis of a Thomas-Fermi-Molière potential, whereas electronic interactions are characterized by Firsov theory or PASS code. Differences between the full and the restricted stopping cross section depend on target thickness and opening angle of the detector and need to be taken into account in comparisons with theory as well as in applications of stopping data. It follows that the reciprocity principle can be violated when checked on restricted instead of full electronic stopping cross sections. Finally, we assert that a seeming gas-solid difference in stopping of low-energy ions is actually a metal-insulator difference. In comparisons with experimental results we mostly consider proton data, where nuclear stopping is only a minor perturbation.

    Full Text Available Causes for loss-to-follow-up, including early refusals of and stopping antiretroviral therapy (ART, in Malawi's Option B+ program are poorly understood. This study examines the main barriers and facilitators to uptake and adherence to ART under Option B+. In depth interviews were conducted with HIV-infected women who were pregnant or postpartum in Lilongwe, Malawi (N = 65. Study participants included women who refused ART initiation (N = 10, initiated ART and then stopped (N = 26, and those who initiated ART and remained on treatment (N = 29. The barriers to ART initiation were varied and included concerns about partner support, feeling healthy, and needing time to think. The main reasons for stopping ART included side effects and lack of partner support. A substantial number of women started ART after initially refusing or stopping ART. There were several facilitators for re-starting ART, including encouragement from community health workers, side effects subsiding, decline in health, change in partner, and fear of future sickness. Amongst those who remained on ART, desire to prevent transmission and improve health were the most influential facilitators. Reasons for refusing and stopping ART were varied. ART-related side effects and feeling healthy were common barriers to ART initiation and adherence. Providing consistent pre-ART counseling, early support for patients experiencing side effects, and targeted efforts to bring women who stop treatment back into care may improve long term health outcomes.

    Methods were developed to calculate: (1) the stopping power of a hot plasma target, (2) the charge-state of a fast ion projectile, and (3) the final disposition of the deposited energy. The first issue refers to the stopping power for protons. The proton stopping power is altered in high-density or high-temperature targets, especially at velocities below the stopping peak. The second issue concerns the application of a proton stopping curve to the arbitrary projectile. The third topic is more specialized to inertial fusion and concerns the partition of deposited energy between ion (nuclear motion) degrees of freedom and those corresponding to bound and free electrons. The question here is whether a thermal equilibrium plasma is produced

    Sabel, Laura; Marzullo, Keith

    1994-01-01

    The fail-stop failure model appears frequently in the distributed systems literature. However, in an asynchronous distributed system, the fail-stop model cannot be implemented. In particular, it is impossible to reliably detect crash failures in an asynchronous system. In this paper, we show that it is possible to specify and implement a failure model that is indistinguishable from the fail-stop model from the point of view of any process within an asynchronous system. We give necessary conditions for a failure model to be indistinguishable from the fail-stop model, and derive lower bounds on the amount of process replication needed to implement such a failure model. We present a simple one-round protocol for implementing one such failure model, which we call simulated fail-stop.

    We have developed a code STOPPO which can be used to modify the more-widely used ion implantation codes to more accurately predict the mean nuclear and electronic stopping power, preferential sputtering and range of heavy ions in monatomic target materials. In our simulations an effective atomic number and effective atomic mass are introduced into conveniently available analytical stopping cross-sections and a better fitting function for preferential sputtering yield is carefully evaluated for each ion implantation. The accuracy of the code confirmed experimentally by comparison with measured Rutherford backscattering spectrometry (RBS) concentration profiles for 130 keV Zr ions implanted into Be to fluences of 1 x 10 17 , 2 x 10 17 and 4 x 10 17 ions/cm 2 . We find a steady increase in the mean nuclear and electronic stopping powers of the target; the increase in nuclear stopping power is much greater than the increase in electronic stopping power

    2008-06-01

    Full Text Available A stopped-flow injection (FI spectrophotometric procedure based on iodometric reaction for the determination of chlorate has been developed. Standard/sample was injected into a stream of potassium iodide solution and then merged with a stream of hydrochloric acid solution to produce triiodide. By stopping the flow while the sample zone is being in a mixing coil, a slow reaction of chlorate with iodide in acidic medium was promoted to proceed with minimal dispersion of the triiodide product zone. When the flow started again, a concentrated product zone was pushed into a flow cell and a signal profile due to light absorption of the product was recorded. Employing a lab-built semi-automatic stopped-FI analyser, the analysis can be performed with higher degree of automation and low chemical consumption. Linear calibration graph in the range of 5-50 mg ClO3- L-1 was obtained, with detection limit of 1.4 mg ClO3- L-1. Relative standard deviation of 2.2% (30 mg ClO3- L-1, n=10 and sample throughput of about 20 h-1 were achieved. The system was applied to soil samples and validated by batch spectrophotometric and standard titrimetric methods.

    An apparatus and method for evaluating a state of an electronic or integrated circuit (IC), each IC including one or more processor elements for controlling operations of IC sub-units, and each the IC supporting multiple frequency clock domains. The method comprises: generating a synchronized set of enable signals in correspondence with one or more IC sub-units for starting operation of one or more IC sub-units according to a determined timing configuration; counting, in response to one signal of the synchronized set of enable signals, a number of main processor IC clock cycles; and, upon attaining a desired clock cycle number, generating a stop signal for each unique frequency clock domain to synchronously stop a functional clock for each respective frequency clock domain; and, upon synchronously stopping all on-chip functional clocks on all frequency clock domains in a deterministic fashion, scanning out data values at a desired IC chip state. The apparatus and methodology enables construction of a cycle-by-cycle view of any part of the state of a running IC chip, using a combination of on-chip circuitry and software.

  8. Reversible airfoils for stopped rotors in high speed flight

    International Nuclear Information System (INIS)

    Niemiec, Robert; Jacobellis, George; Gandhi, Farhan

    2014-01-01

    This study starts with the design of a reversible airfoil rib for stopped-rotor applications, where the sharp trailing-edge morphs into the rounded leading-edge, and vice-versa. A NACA0012 airfoil is approximated in a piecewise linear manner and straight, rigid outer profile links used to define the airfoil contour. The end points of the profile links connect to control links, each set on a central actuation rod via an offset. Chordwise motion of the actuation rod moves the control and the profile links and reverses the airfoil. The paper describes the design methodology and evolution of the final design, based on which two reversible airfoil ribs were fabricated and used to assemble a finite span reversible rotor/wing demonstrator. The profile links were connected by Aluminum strips running in the spanwise direction which provided stiffness as well as support for a pre-tensioned elastomeric skin. An inter-rib connector with a curved-front nose piece supports the leading-edge. The model functioned well and was able to reverse smoothly back-and-forth, on application and reversal of a voltage to the motor. Navier–Stokes CFD simulations (using the TURNS code) show that the drag coefficient of the reversible airfoil (which had a 13% maximum thickness due to the thickness of the profile links) was comparable to that of the NACA0013 airfoil. The drag of a 16% thick elliptical airfoil was, on average, about twice as large, while that of a NACA0012 in reverse flow was 4–5 times as large, even prior to stall. The maximum lift coefficient of the reversible airfoil was lower than the elliptical airfoil, but higher than the NACA0012 in reverse flow operation. (paper)

    2013-06-21

    In 1988, the Global Polio Eradication Initiative (GPEI) was established through a partnership between the World Health Organization (WHO), Rotary International, CDC, and the United Nations Children's Fund (UNICEF). By 2012, the annual incidence of polio had decreased by >99%, compared with 1988, and the number of countries in which wild poliovirus (WPV) circulation has never been interrupted was reduced to three: Afghanistan, Nigeria, and Pakistan. However, because of the persistence of endemic WPV transmission and recurring outbreaks in polio-free countries after the original polio eradication target date of 2000, the World Health Assembly in 2012 declared the completion of polio eradication a programmatic emergency. A key component of GPEI is the Stop Transmission of Polio (STOP) program, which was developed and initiated by CDC with WHO in 1999 to mobilize additional human resources and technical assistance for countries affected by WPV transmission. During 1999-2013, 1,563 volunteers were identified, trained, and deployed for 2,221 assignments in 69 countries. The number of volunteers increased from 90-120 per year during 1999-2011 to 287 in 2012 and 378 in 2013, and the number of volunteer person-months in the field per year increased from 273 in 1999 to 1,456 in 2012. The STOP program has aided GPEI by strengthening the capacity of country-level immunization programs and by allowing a large cohort of volunteers to gain valuable field experience that prepares them well for subsequent work as staff members of WHO, UNICEF, and other public health agencies.

    Highlights: • Partial dehydration reduces energy consumption and processing time and improves product quality. • This study gives a quantitative insight in when fruit drying should be stopped. • Decrease in dryer residence time of 2%, 24% and 70% are found for different stopping criteria. - Abstract: Stopping the drying process prior to complete dehydration reduces energy consumption and processing time but can also improve product quality. Using hygrothermal simulations, different stopping criteria are evaluated, which are based on the final water activity and residual moisture content in the fruit. Their impact on drying time and moisture redistribution kinetics inside fruit is quantified. One of the variants leads to a significant reduction in residence time in the dryer (24%), compared to full dehydration. For this variant, drying is stopped when the average moisture content in the sample reaches the value corresponding to an equilibrium water activity of 60% in the sample, as determined from the sorption isotherm. At the same time, this variant does not induce problems with fruit spoilage, as a sufficiently low water activity is reached after moisture redistribution during relaxation in the ambient environment. In addition, the relation of the drying time to the drying air temperature was quantified for all stopping criteria, as well as the impact of the humidity of the ambient environment in which the dried fruits are placed afterwards. This study gives a better quantitative insight in when fruit drying should be stopped, given specific drying conditions, without having to compromise food safety.

    Illustrated by many drawings and graphs, this report describes and comments all operations and measurements to be performed for starting up the Saturne synchrotron until particle acceleration exclusively. The author reports the study of beam as it goes out of the Van de Graaff: experiment of position and stability of the beam axis, study of beam current and geometric characteristics (calibration of the induction probe), experiment of mass separation and proton percentage, and adjustment of regulation and Van de Graaff fall law. In a second part, he reports the optics alignment and the study of optics property (installation of the different sectors, study of inflector end voltage, and influence of inflector position in the chamber). The third part addresses the examination of phenomena associated with injection: injection method and definition of the initial instant, search for injection optimum conditions, study of particle lifetime and of phenomena on the inner probe. The fourth part proposes theoretical additional elements regarding the movement of particles at the injection in the useful area, and phenomena occurring on targets and on the inner probe

  13. STARCODES, Stopping Power and Ranges for Electrons, Protons, He

    International Nuclear Information System (INIS)

    2000-01-01

    1 - Description of program or function: The 'STAR CODES', ESTAR, PSTAR, and ASTAR, calculate stopping-power and range tables for electrons, protons, and helium ions (alphas), according to methods described in ICRU Reports 37 and 39. 2 - Method of solution: Collision stopping powers are calculated from the theory of Bethe (1930, 1932), with a density-effect correction evaluated according to Sternheimer (1952, 1982). The stopping-power formula contains an important parameter, the mean excitation energy (I-value), which characterizes the stopping properties of a material. The codes provide output for electrons in any stopping material (279 provided) and for protons and helium ions in 74 materials. The calculations include the 1) Collision stopping power, 2) Radiative stopping power (electrons only), 3) Nuclear stopping power (protons and helium ions), 4) Total stopping power, 5) CSDA range, 6) Projected range (protons and helium ions), 7) Density effect parameter (electrons), 8) Radiation yield (electrons), and 9) Detour factor (protons and helium ions). Standard energy grids and files of elements w/ionization-excitation information are included with lookup table capabilities. 3 - Restrictions on the complexity of the problem: The minimum energies used in the calculations are at 1 KeV (protons and helium ions) and 10 KeV (electrons), and the maximum are 1 GeV. The standard energy grids are set at 81 for electrons, equally spaced (logarithmically), 133 for protons, and 122 for helium ions. The lower energy electron calculations (< 10 KeV) have up to 5-10% errors and are considered too fallable

    In supersymmetric extensions of the Standard Model, the superpartners of the top quark (stops) play the crucial role in addressing the naturalness problem. For direct pair-production of stops with each stop decaying into a top quark plus the lightest neutralino, the standard stop searches have difficulty finding the stop for a compressed spectrum where the mass difference between the stop and the lightest neutralino is close to the top quark mass, because the events look too similar to the large tt̄ background. With an additional hard ISR jet, the two neutralinos from the stop decays are boosted in the opposite direction and they can give rise to some missing transverse energy. This may be used to distinguish the stop decays from the backgrounds. In this paper we study the semileptonic decay of such signal events for the compressed mass spectrum. Although the neutrino from the W decay also produces some missing transverse energy, its momentum can be reconstructed from the kinematic assumptions and mass-shell conditions. It can then be subtracted from the total missing transverse momentum to obtain the neutralino contribution. Because it suffers from less backgrounds, we show that the semileptonic decay channel has a better discovery reach than the fully hadronic decay channel along the compressed line m{sub t̃}−m{sub χ̃}≈m{sub t}. With 300 fb{sup −1}, the 13 TeV LHC can discover the stop up to 500 GeV, covering the most natural parameter space region.

  15. Stopping power. Projectile and target modeled as oscillators

    In this Letter the collision of two quantum harmonic oscillators was considered. The oscillators interact through the Coulomb interaction. Stopping power of projectile was calculated assuming that both, target and projectile may be excited. It has been shown that the frequency of the projectile oscillation, ω p influences on stopping power, particularly in the region of Bragg peak. If, ω p ->0 is substitute in the expression for stopping power derived in this Letter, then it comes to the form when the projectile has been treated as point like charged particle

    The theory of heavy ion stopping by electrons in solids is analyzed with an aim to establish which physical mechanisms are of importance at different ion velocity values v. The theory is presented for deep inelastic collisions taking the main part in stopping at v > Zsub(1)sup(1/3) v 0 (z 1 is the atomic number of the ion, v 0 is the Bohr velocity). Elastic scattering (relative to the incident ion) are investigated. It is shown that the contribution from these processes to the stopping cross-section is predominant at Zsub(1)sup(1/3) v 0 > v > Zsub(1)sup(2/3) v 0

    Full Text Available Hindko is an Indo-Aryan language that is mainly spoken in Khyber Pukhtoonkhaw province of Pakistan. This work aims to identify the oral stops of Hindko and determine the intrinsic acoustic cues for them. The phonemic analysis is done with the help of minimal pairs and phoneme distribution in contrastive environments which reveals that Hindko has twelve oral stops with three way series. The acoustic analysis of these segments shows that intrinsically voice onset time (VOT, closure duration and burst are reliable and distinguishing cues of stops in Hindko.

    Little is known about how older persons in home care express their concerns. Emotional cues and concerns can be identified by the Verona coding definitions of emotional sequences (VR-CoDES), but the method gives no insight into what causes the distress and the emotions involved. The aims of this study are to explore (1) older persons' worries and (2) the content of these expressions. An observational exploratory two-step approach was used to investigate audiotaped recordings from 38 Norwegian home care visits with older persons and nurse assistants. First, 206 cues and concerns were identified using VR-CoDES. Second, the content and context of these expressions were analysed inductively. Four main categories emerged: worries about relationships with others, worries about health care-related issues, worries about aging and bodily impairment, and life narratives and value issues, with several subcategories showing the causes of worry and emotions involved. The two-step approach provides an in-depth knowledge of older persons' worries, causes of worries, and their related emotions. The subcategories described in a language close to the experience can be useful in practice development and communication training for students and health care providers.

    This study relates predictions on reactive and proactive cognitive control to findings on anxious apprehension/worry and ERN/Ne. We investigated whether worry-inducing stimuli in an aversive performance setting lead to a more pronounced increase of the ERN/Ne in individuals with lower anxious apprehension/worry. We also explored the N2 amplitude in the context of worry-inducing stimuli. Fifty-eight participants performed an extended Go/NoGo task. A neutral or fearful face was presented at the beginning of each trial, with the fearful face as a worry-inducing, distracting stimulus. In an aversive feedback condition, aversive feedback was provided for false or too slow responses. We found a more pronounced decrease of the ERN/Ne after worry-inducing stimuli compared to neutral stimuli in participants with lower anxious apprehension/worry. Moreover, less pronounced N2 amplitudes were associated with shorter reaction times in the aversive feedback condition. Implications for future research on error monitoring and trait-anxiety are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Chagas disease (CD) profoundly affects the social and emotional dimensions of patients' lives, and disproportionately impacts poor, marginalized populations in Latin America. Biomedical treatment for CD fails to reach up to 99% of the people affected, and in any case seldom addresses the emotional health or socioeconomic conditions of patients. This study examines patient strategies for coping with CD in the department of Santa Cruz, Bolivia. In this ethnographic study, semistructured interviews took place from March-June 2013 with 63 patients who had previously tested positive for CD. During the fieldwork period, participant observation was conducted and patient family members, providers, community members, and public health officials were consulted. Patients often experienced emotional distress when diagnosed with CD, yet were generally unable to find biomedical treatment. Respondents stressed the need to avoid powerful emotions which would worsen the impact of CD symptoms. To manage CD, patients embraced a calm state of mind, described in Spanish as tranquilidad, which partially empowered them to return to a normal existence. In the perceived absence of biomedical treatment options, patients seek their own means of coping with CD diagnosis. Rather than fatalism or resignation, patients' emphasis on maintaining calm and not worrying about CD represents a pragmatic strategy for restoring a sense of normalcy and control to their lives. Programs focused on treatment of CD should remain mindful of the emotional and social impact of the disease on patients.

  1. Ten years after "Worrying trends in econophysics": developments and current challenges

    2016-12-01

    Econophysics has made a number of important additions to scientific knowledge. Yet it continues to lack influence with both economists and policy makers. Ten years ago, I and three other economists sympathetic to econophysics wrote a paper on worrying trends within the discipline. For example, its lack of awareness of the economics literature, and shortfalls in the use of statistical analysis. These continue to be obstacles to wider acceptance by economists. Like all agents, policy makers respond to incentives, and economists understand this very well. Much of the econophysics community appears to think that simply doing good science is sufficient to have the work recognised, rather than relating to the motivations and incentives of policy makers. Nevertheless, econophysics now has three major opportunities to advance knowledge in areas where policy makers perceive weaknesses in what they are presented with by economists. All can benefit from the analysis of Big Data. The first is a core model of agent behaviour which is more relevant to cyber society than the rational agent model of economics. Second, extending our understanding of the business cycle, primarily by incorporating the importance of networks into models. Third, devising proper measures of output in cyber society.

    Biological, environmental, inter- and intrapersonal changes during the antenatal period can result in anxiety and stress in pregnant women. It is pivotal to identify potential stressors and prevent their foetal and maternal consequences. The present study was conducted to validate and examine the factor structure of the Farsi version of the Pregnancy Worries and Stress Questionnaire (PWSQ). In 2015, 502 Iranian healthy pregnant women, referred to selected hospitals in Tehran for prenatal care at 8-39 weeks of pregnancy, were recruited through a randomized cluster sampling. The PWSQ was translated into Farsi, and its validity and reliability were examined using exploratory factor analysis by SPSS version 21. The content validity of items on the PWSQ was between 0.63-1. The content validity index for relevance, clarity and simplicity were 0.92, 0.98, and 0.98, respectively, with a mean of 0.94. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.863. Test-retest reliability showed high internal consistency (α=0.89; p<0.0001). The psychometric evaluation and exploratory factor analysis showed that the translated questionnaire is a valid and reliable tool to identify stress in Iranian pregnant women. Application of the questionnaire can facilitate the diagnosis of stress in pregnant women and assist health care providers in providing timely support and minimizing negative outcomes of stress and anxiety in pregnant women and their infants.

    2015-01-01

    Full Text Available Unsuitable locations of bus stops which provide feeder transportation connecting subways near urban intersections usually lead to the low efficiency of public transport and level of passenger service. A multiobjective optimization model to distribute such stop locations is proposed to attain the shortest total walk distance of passengers and minimum delay time of cars through intersections and travel time of buses. The Pareto frontier and optimal solutions for the proposed model are given by the distance-based and enumerative methods. The Xizhimen bus stop is selected to implement case studies for verifying the validity of the proposed model. The analysis of sensitivity on possible solutions is also carried out in the case studies. The results show that the proposed model is capable of optimizing the locations of bus stops connecting subways near intersections and helpful to improve the level of passengers service and operational efficiency of public transportation.

  8. Higgs-Stoponium Mixing Near the Stop-Antistop Threshold

    2016-01-01

    Supersymmetric extensions of the standard model contain additional heavy neutral Higgs bosons that are coupled to heavy scalar top quarks (stops). This system exhibits interesting field theoretic phenomena when the Higgs mass is close to the stop-antistop production threshold. Existing work in the literature has examined the digluon-to-diphoton cross section near threshold and has focused on enhancements in the cross section that might arise either from the perturbative contributions to the Higgs-to-digluon and Higgs-to-diphoton form factors or from mixing of the Higgs boson with stoponium states. Near threshold, enhancements in the relevant amplitudes that go as inverse powers of the stop-antistop relative velocity require resummations of perturbation theory and/or nonperturbative treatments. We present a complete formulation of threshold effects at leading order in the stop-antistop relative velocity in terms of nonrelativistic effective field theory. We give detailed numerical calculations for the case in ...

    Electronic stopping cross sections for 7 Li projectiles (840--175 keV) have been measured with the inverted Doppler-shift attenuation method in liquid ethane (C 2 H 6 ) at two different densities. The density of the target has been varied by changing the temperature, and measurements have been performed at 0.525 g/cm 3 (199 K) and 0.362 g/cm 3 (287 K). At the higher density the stopping cross section is about 2% smaller. This result agrees with a calculation of the stopping cross section of liquid ethane, applying Lindhard's theory in the local-density approximation using a simple model of the liquid. It is also in agreement with various observations of the so-called physical-state effect, which show that the stopping cross section of the same substance is smaller in a condensed phase than in the gaseous one

    The problem of stopping power (SP) for projectile ions is analysed in terms of the dielectric function and effective collision frequency for moderately dense and strongly coupled plasmas (SCP). We consider several issues regarding the calculation of stopping power for correlated ensembles of particles and oscillators. In particular, effects of group (few particle) modes, transition from positive to negative dispersion and excitation of collective modes up to suprathermal level at plasma targets are addressed. Linear SP of dense suprathermal (nonlinear) plasma targets at different levels of target plasma turbulence is estimated. The force of suprathermal plasma oscillations on the projectile ions is mostly in the nature of increased frictional drag. The results obtained show the possibility of increasing low velocity stopping (up to 'turbulent' values) in comparison with losses in equilibrium dense plasma targets. Experimental conditions to create specific turbulent targets as well as some connection between stopping phenomena and SCP transport properties are discussed briefly.

Without any decision-support system, it is very difficult for drivers to stop trains within stations with consistency in one braking action. The reasons are that braking performance of train changes with the conditions of braking equipment and the drivers’ subjective evaluations of track profiles and braking distance are vague and imprecise.

  18. Motor Preparation Disrupts Proactive Control in the Stop Signal Task

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available In a study of the stop signal task (SST we employed Bayesian modeling to compute the estimated likelihood of stop signal or P(Stop trial by trial and identified regional processes of conflict anticipation and response slowing. A higher P(Stop is associated with prolonged go trial reaction time (goRT—a form of sequential effect—and reflects proactive control of motor response. However, some individuals do not demonstrate a sequential effect despite similar go and stop success (SS rates. We posited that motor preparation may disrupt proactive control more in certain individuals than others. Specifically, the time interval between trial and go signal onset—the fore-period (FP—varies across trials and a longer FP is associated with a higher level of motor preparation and shorter goRT. Greater motor preparatory activities may disrupt proactive control. To test this hypothesis, we compared brain activations and Granger causal connectivities of 81 adults who demonstrated a sequential effect (SEQ and 35 who did not (nSEQ. SEQ and nSEQ did not differ in regional activations to conflict anticipation, motor preparation, goRT slowing or goRT speeding. In contrast, SEQ and nSEQ demonstrated different patterns of Granger causal connectivities. P(Stop and FP activations shared reciprocal influence in SEQ but FP activities Granger caused P(Stop activities unidirectionally in nSEQ, and FP activities Granger caused goRT speeding activities in nSEQ but not SEQ. These findings support the hypothesis that motor preparation disrupts proactive control in nSEQ and provide direct neural evidence for interactive go and stop processes.

    1985-01-01

    We calculate the stopping power of the degenerate electron liquid at metallic densities in the dielectric formalism. The strong Coulomb-coupling effects beyond the random-phase approximation are taken into account through the static and dynamic local-field corrections. It is shown that those strong-coupling and dynamic effects act to enhance the stopping power substantially in the low-velocity regime, leading to an improved agreement with experimental data.

We try to reproduce the experimental fundamental diagram (velocity versus density) with simulations. In addition to this quantitative criterion, we tried to reproduce stop-and-go waves as a qualitative criterion. Stop-and-go waves are a characteristic phenomenon for the single file movement. Only one of three investigated models satisfies both criteria.

    Generalized anxiety disorder (GAD) has undergone a series of substantial classificatory changes since its first inclusion in DSM-III. The majority of these revisions have been in response to its poor inter-rater reliability and concerns that it may lack diagnostic validity. This article provides options for the revision of the DSM-IV GAD criteria for DSM-V. First, searches were conducted to identify the evidence that previous DSM Work Groups relied upon when revising the DSM-III-R GAD and the overanxious disorder classifications. Second, the literature pertaining to the DSM-IV criteria for GAD was examined. The review presents a number of options to be considered for DSM-V. One option is for GAD to be re-labeled in DSM-V as generalized worry disorder. This would reflect its hallmark feature. Proposed revisions would result in a disorder that is characterized by excessive anxiety and worry generalized to a number of events or activities for 3 months or more. Worry acts as a cognitive coping strategy that manifests in avoidant behaviors. The reliability and validity of the proposed changes could be investigated in DSM-V validity tests and field trials.

We examined whether a smartphone-based worry-reduction training improved a physiological marker of stress (i.e. increased heart rate variability [HRV]) and unconscious stress. Randomised-controlled trial was conducted with individuals reporting work stress (n = 136). Participants were randomised to the experimental, control or waitlist condition (resp. EC, CC, WL). The EC and CC registered emotions five times daily for four weeks. The EC additionally received a worry-reduction training with mindfulness exercises. Primary outcome was 24-h assessments of HRV measured at pre-, mid- and post-intervention. Secondary outcomes were implicit affect and stress. Effects on heart rate and other psychological outcomes were explored. A total of 118 participants completed the study. No change from pre- to post-intervention was observed for the primary or secondary outcomes. The change over time was not different between conditions. Findings suggest that the training was ineffective for improving HRV or psychological stress. Future studies may focus on alternative smartphone-based stress interventions, as stress levels are high in society. There is need for easy interventions and smartphones offer possibilities for this.

    To determine the relationship between beliefs, motivation, and worries about physical activity and physical activity participation in persons with rheumatoid arthritis (RA). A cross-sectional study used baseline data from 185 adults with RA enrolled in a randomized clinical trial assessing the effectiveness of an intervention to promote physical activity. Data included patients' self-reported beliefs that physical activity can be beneficial for their disease, motivation for physical activity participation, worries about physical activity participation, and average daily accelerometer counts of activity over a week's time. Body mass index (BMI), sex, age, race, and disease activity were measured as potential statistical moderators of physical activity. Physical activity participation was greater for those with higher scores on scales measuring beliefs that physical activity is beneficial for their disease (P for trend = 0.032) and motivation for physical activity participation (P for trend = 0.007) when adjusted for age, sex, BMI, race, and disease activity. There was a positive but nonsignificant trend in physical activity participation in relation to worries. Stronger beliefs that physical activity can be helpful for managing disease and increased motivation to engage in physical activity are related to higher levels of physical activity participation. These data provide a preliminary empirical rationale for why interventions targeting these concepts should lead to improved physical activity participation in adults with RA.

  11. Managing yourself. Stop overdoing your strengths.

    Although most managers can recognize an off-kilter leader (consider the highly supportive boss who cuts people too much slack), it's quite difficult to see overkill in yourself. Unfortunately, that's where leadership development tools such as 360-degree surveys fail to deliver, say Kaplan and Kaiser. Dividing qualities into "strengths" and "weaknesses" and rating them on a five-point scale will not account for strengths overplayed. The authors suggest several strategies, based on their years of consulting experience and research, for figuring out which attributes you've employed to excess and adjusting your behavior accordingly. Strengths taken too far have two consequences: First, they become weaknesses. For instance, quick-wittedness can turn into impatience with others. Second, you're at risk of becoming extremely lopsided--that is, diminishing your capacity on the opposite pole. A leader who is very good at building consensus, for example, may take too long to move into action. To strike a balance between two key leadership dualities--forceful versus enabling, and strategic versus operational--you need to see your actions and motivations clearly. That's no easy task since most leadership development tools don't spell out that you're overdoing your strengths. But there are other ways to bring that information to light. You can start with a review of the highest ratings on your most recent 360 report. Ask yourself: Is this too much of a good thing? Another technique is to make a list of the traits you most want to have as a leader. Are you going to extremes with any of them? To check for lopsidedness, you can prompt feedback from other people with a list of qualities you've composed or one you've gleaned from other sources. Once you know which attributes you're overdoing, you can recalibrate.

  12. The frequentist implications of optional stopping on Bayesian hypothesis tests.

    Null hypothesis significance testing (NHST) is the most commonly used statistical methodology in psychology. The probability of achieving a value as extreme or more extreme than the statistic obtained from the data is evaluated, and if it is low enough, the null hypothesis is rejected. However, because common experimental practice often clashes with the assumptions underlying NHST, these calculated probabilities are often incorrect. Most commonly, experimenters use tests that assume that sample sizes are fixed in advance of data collection but then use the data to determine when to stop; in the limit, experimenters can use data monitoring to guarantee that the null hypothesis will be rejected. Bayesian hypothesis testing (BHT) provides a solution to these ills because the stopping rule used is irrelevant to the calculation of a Bayes factor. In addition, there are strong mathematical guarantees on the frequentist properties of BHT that are comforting for researchers concerned that stopping rules could influence the Bayes factors produced. Here, we show that these guaranteed bounds have limited scope and often do not apply in psychological research. Specifically, we quantitatively demonstrate the impact of optional stopping on the resulting Bayes factors in two common situations: (1) when the truth is a combination of the hypotheses, such as in a heterogeneous population, and (2) when a hypothesis is composite-taking multiple parameter values-such as the alternative hypothesis in a t-test. We found that, for these situations, while the Bayesian interpretation remains correct regardless of the stopping rule used, the choice of stopping rule can, in some situations, greatly increase the chance of experimenters finding evidence in the direction they desire. We suggest ways to control these frequentist implications of stopping rules on BHT.

    Few prospective studies have examined associations between breast cancer worry and screening behaviours in women with elevated breast cancer risks based on family history. Methods. This study included 901 high familial risk women, aged 23-71 years, from the Ontario site of the Breast Cancer Family Registry. Self-reported breast screening behaviours at year-one followup were compared between women at low (N=305), medium ( N=433), and high (N=163) levels of baseline breast cancer worry using logistic regression. Nonlinear relationships were assessed using likelihood ratio tests. Results. A significant non-linear inverted “U” relationship was observed between breast cancer worry and mammography screening (π=0. 034) for all women, where women at either low or high worry levels were less likely than those at medium to have a screening mammogram. A similar significant non-linear inverted “U” relationship was also found among all women and women at low familial risk for worry and screening clinical breast examinations (CBEs). Conclusions. Medium levels of cancer worries predicted higher rates of screening mammography and CBE among high-risk women

    Full Text Available The article is an edited conversation with an activist of an initiative “Stop the fracking in Slovenia”. In order to start the process of fracking for natural gas extraction in the Prekmurje region, companies still have to obtain some environmental permits from the government environmental agency, which seems to have taken the companies’ side. The initiative is struggling to stop this. The conversation was focused on the developments in the Petišovci fields, formal procedures connected to obtaining permits, and the companies involved. The article also contains the explanation of what fracking is.

    A light stop with mass almost degenerate with the lightest neutralino has important connections with both naturalness and dark matter relic abundance. This region is also very hard to probe at colliders. In this paper, we demonstrate the potential of searching for such stop particles at the LHC from sbottom decays, focusing on two channels with final states 2ℓ+E{sub T}{sup miss} and 1b1ℓ+E{sub T}{sup miss}. We found that, if the lightest sbottom has mass around or below 1 TeV and has a significant branching ratio to decay to stop and W (b̃→t̃ W), a stop almost degenerate with neutralino can be excluded up to about 500–600 GeV at the 13 TeV LHC with 300 fb{sup −1} data. The searches we propose are complementary to other SUSY searches at the LHC and could have the best sensitivity to the stop-bino coannihilation region. Since they involve final states which have already been used in LHC searches, a reinterpretation of the search results already has sensitivity. Further optimization could deliver the full potential of these channels.

    The stopping time of a one-dimensional bounded classical random walk (RW) is defined as the number of steps taken by a random walker to arrive at a fixed boundary for the first time. A quantum walk (QW) is a non-trivial generalization of RW, and has attracted a great deal of interest from researchers working in quantum physics and quantum information. In this paper, we develop a method to calculate the stopping time for a one-dimensional QW. Using our method, we further compare the properties of stopping time for QW and RW. We find that the mean value of the stopping time is the same for both of these problems. However, for short times, the probability for a walker performing a QW to arrive at the boundary is larger than that for a RW. This means that, although the mean stopping time of a quantum and classical walker are the same, the quantum walker has a greater probability of arriving at the boundary earlier than the classical walker.

  18. Reciprocity in the electronic stopping of slow ions in matter

    The principle of reciprocity, i.e., the invariance of the inelastic excitation in ion-atom collisions against interchange of projectile and target, has been applied to the electronic stopping cross section of low-velocity ions and tested empirically on ion-target combinations supported by a more or less adequate amount of experimental data. Reciprocity is well obeyed (within ∼10%) for many systems studied, and deviations exceeding ∼20% are exceptional. Systematic deviations such as gas-solid or metal-insulator differences have been looked for but not identified on the present basis. A direct consequence of reciprocity is the equivalence of Z 1 with Z 2 structure for random slowing down. This feature is reasonably well supported empirically for ion-target combinations involving carbon, nitrogen, aluminium and argon. Reciprocity may be utilized as a criterion to reject questionable experimental data. In cases where a certain stopping cross section has not been or cannot be measured, the stopping cross section for the inverted system may be available and serve as a first estimate. It is suggested to build in reciprocity as a fundamental requirement into empirical interpolation schemes directed at the stopping of low-velocity ions. Examination of the SRIM and MSTAR codes reveals cases where reciprocity is obeyed accurately, but deviations of up to a factor of two are common. In case of heavy ions such as gold, electronic stopping cross sections predicted by SRIM are asserted to be almost an order of magnitude too high. (authors)

    The effects that the stopping of nuclear power generation exerts on the price of primary energy such as petroleum, LNG and coal and the trend of Japanese energy and economy are analyzed by using the medium term economy forecasting system. In the simulation, the case of stopping nuclear power generation in seven countries of OECD is supposed, and as for the process of stopping, two cases of immediate stopping and stopping by gradual reduction are set up. The models used for the simulation are the world energy model, the competition among energies model and the multiple category model. By the decrease of nuclear power generation, thermal power generation increases, and the demand of fossil fuel increases. As the result, the price of fossil fuel rises (the world energy model), and the price of fossil fuel imported to Japan rises. Also the quantity of fossil fuel import to Japan increase. These price rise and quantity increase exert deflation effect to Japanese economy (the multiple category model). The price rise of fossil fuel affects the competition among energies in Japan through the relative change of secondary energy price (the competition among energies model). The impact to the world and to Japan is discussed. (K.I.)
