Derived shortened versions of the AutomaticThoughtsQuestionnaire (ATQ) (S. Hollon and P. Kendall, 1980) using samples of 434 and 419 adults. Cross-validation with samples of 163 and 91 adults showed support for the shortened versions. Overall, results suggest that these short forms are useful in measuring cognitions associated with depression.…

We examined two recently developed measures of positive automaticthought, the Positive AutomaticThoughtsQuestionnaire (ATQ-P)\\u000a and the AutomaticThoughtsQuestionnaire—Revised (ATQ-RP). Internal consistency, concurrent validity, and convergent and discriminant\\u000a validity were addressed. Two hundred one undergraduates completed self-report measures of positive automaticthoughts, negative\\u000a automaticthoughts, depressive symptoms, anxiety symptoms, and positive affectivity. The ATQ-P and ATQ-RP both showed
A 30-item questionnaire was devised to measure the frequency of occurrence of automatic negative thoughts (negative self-statements)associated with depression. Male and female undergraduates were asked to recall dysphoric experiences and to report associated cognitions. One hundred representative cognitions were selected and administered to a second sample, along with the MMPI D scale and the Beck Depression Inventory. Thirty items discriminating
Objectives. This research was carried out in two stages: the objectives of the first stage were (1) to identify the existing relationships between the level of anxiety, the frequency of automatic negative thoughts, and unconditional self-acceptance and (2) to capture the existing differences regarding these variables between people diagnosed with rheumatoid arthritis and those with no such medical history. Methods. The sample made up of 50 subjects filled out the following three questionnaires: the Hamilton Anxiety Scale, the AutomaticThoughtsQuestionnaire, and the Unconditional Self-Acceptance Questionnaire. Results. Psychological anxiety is positively correlated with automatic negative thoughts, while unconditional self-acceptance is negatively correlated with both psychological anxiety and somatic anxiety as well as with automatic negative thoughts. All studied variables were significantly different in rheumatoid arthritis as compared to the control population. Conclusions. The results showed the presence to a greater extent of anxiety and automatic negative thoughts, along with reduced unconditional self-acceptance among people with rheumatoid arthritis. Intervention on these variables through support and counseling can lead to reducing anxiety and depression, to altering the coping styles, and, implicitly, to improving the patients' quality of life.

We examined the psychometric properties of the Dutch version of the Attitudes to Chocolate Questionnaire (ACQ), comparing the original three-factor model to a later-suggested two-factor model. We evaluated the construct validity of the ACQ by investigating the associations between the resulting factors and other eating-related questionnaires such as the Three Factor Eating Questionnaire and the Food Thought Suppression Inventory. Finally, we compared the scores on several scales regarding eating behavior between different groups (men versus women, dieters versus non-dieters and cravers versus non-cravers). A confirmatory factor analysis of the Dutch ACQ indicated the best global fit indices for the two-factor model, with the resulting factors being "Negative consequences and Guilt" and "Craving and emotional eating". Both factors were associated with other eating-related dimensions. However, craving seemed to be uniquely associated with the amount of chocolate consumed per week, whereas guilt correlated strongly with restraint. Finally, women scored higher on nearly all scales, but there was no significant gender difference with regard to chocolate consumption. Dieters reported more disinhibition, restraint, food-thought suppression and guilt, but they did not significantly differ from non-dieters with regards to their levels of craving, hunger nor consumption.

Purpose The aims of the study were to analyze the psychometric properties of the Spanish version of the Thought-Action Fusion Questionnaire (TAF-SP), as well as to determine its validity by evaluating the relationship of the TAF-SP to different instruments. Patients and methods Two groups were studied: one comprising 146 patients with eating disorders; and another a group of 200 students. Results Three factors were obtained: TAF–Moral; TAF–Likelihood-others; and TAF–Likelihood-oneself. The internal consistency of the TAF-SP was determined by means of Cronbach’s ? coefficient, with values ranging between 0.84–0.95. The correlations with other instruments refected adequate validity. The three-factor structure was tested by means of a linear structural equation model, and the structure fit satisfactorily. Differences in TAF-SP scores between the diagnostic subgroups were also analyzed. Conclusion The TAF-SP meets the psychometric requirements for measuring thought-action fusion and shows adequate internal consistency and validity.

In charge of intensity estimations in France, BCSF has collected and manually analyzed more than 47000 online individual macroseismic questionnaires since 2000 up to intensity VI. These macroseismic data allow us to estimate one SQI value (Single Questionnaire Intensity) for each form following the EMS98 scale. The reliability of the automatic intensity estimation is important as they are today used for automatic shakemaps communications and crisis management. Today, the automatic intensity estimation at BCSF is based on the direct use of thumbnails selected on a menu by the witnesses. Each thumbnail corresponds to an EMS-98 intensity value, allowing us to quickly issue an intensity map of the communal intensity by averaging the SQIs at each city. Afterwards an expert, to determine a definitive SQI, manually analyzes each form. This work is time consuming and not anymore suitable considering the increasing number of testimonies at BCSF. Nevertheless, it can take into account incoherent answers. We tested several automatic methods (USGS algorithm, Correlation coefficient, Thumbnails) (Sira et al. 2013, IASPEI) and compared them with 'expert' SQIs. These methods gave us medium score (between 50 to 60% of well SQI determined and 35 to 40% with plus one or minus one intensity degree). The best fit was observed with the thumbnails. Here, we present new approaches based on 3 statistical ranking methods as 1) Multinomial logistic regression model, 2) Discriminant analysis DISQUAL and 3) Support vector machines (SVMs). The two first methods are standard methods, while the third one is more recent. Theses methods could be applied because the BCSF has already in his database more then 47000 forms and because their questions and answers are well adapted for a statistical analysis. The ranking models could then be used as automatic method constrained on expert analysis. The performance of the automatic methods and the reliability of the estimated SQI can be evaluated thanks to the fact that each definitive BCSF SQIs is determined by an expert analysis. We compare the SQIs obtained by these methods from our database and discuss the coherency and variations between automatic and manual processes. These methods lead to high scores with up to 85% of the forms well classified and most of the remaining forms classified with only a shift of one intensity degree. This allows us to use the ranking methods as the best automatic methods to fast SQIs estimation and to produce fast shakemaps. The next step, to improve the use of these methods, will be to identify explanations for the forms not classified at the correct value and a way to select the few remaining forms that should be analyzed by the expert. Note that beyond intensity VI, on-line questionnaires are insufficient and a field survey is indispensable to estimate intensity. For such survey, in France, BCSF leads a macroseismic intervention group (GIM).
Although measures of negative thinking in depression such as the AutomaticThoughtsQuestionnaire have been widely used, comparable measures of positive thinking have not been developed. The lack of such measures has made it difficult to examine both negative and positive change processes as a function of therapeutic interventions.

Dysfunctional self-schemas are assumed to play an important role in suicidal ideation. According to recent information-processing models, it is important to differentiate between ‘explicit’ beliefs and automatic associations. Explicit beliefs stem from the weighting of propositions and their corresponding ‘truth’ values, while automatic associations reflect more simple associations in memory. Both types of associations are assumed to have different functional properties and both may be involved in suicidal ideation. Thus far, studies into self-schemas and suicidal ideation focused on the more explicit, consciously accessible traces of self-schemas and predominantly relied on self-report questionnaires or interviews. To complement these ‘explicit’ findings and more directly tap into self-schemas, this study investigated automatic self-associations in a large scale community sample that was part of the Netherlands Study of Depression and Anxiety (NESDA). The results showed that automatic self-associations of depression and anxiety were indeed significantly related to suicidal ideation and past suicide attempt. Moreover, the interactions between automatic self-depressive (anxious) associations and explicit self-depressive (anxious) beliefs explained additional variance over and above explicit self-beliefs. Together these results provide an initial insight into one explanation of why suicidal patients might report difficulties in preventing and managing suicidal thoughts.

There are few published studies of new mothers' experiences of intrusive thoughts of harm related to the newborn. Evidence-based information about the normal phenomenology of intrusive thoughts of harm related to the newborn is needed to facilitate appropriate clinical decision-making. The objective of this project was to assess the phenomenology, prevalence, correlates, and behavioural sequelae of maternal thoughts of harm related to the newborn. One hundred women were recruited during pregnancy. Participants were assessed prenatally and at 4 and 12 weeks postpartum using questionnaires and a semi-structured interview about unwanted thoughts of harm related to the newborn. Postpartum intrusive thoughts of accidental harm to the infant were universal, and close to half of the sample reported unwanted thoughts of intentionally harming their infant. Compared with intentional harm thoughts, accidental harm thoughts were more frequent and more time consuming, but less distressing. High parenting stress and low social support predicted the occurrence of thoughts of intentional harm. Little evidence of an association between these thoughts and aggressive parenting was found. Unwanted intrusive thoughts of harming one's infant are a relatively normative experience during the early postpartum period, particularly in association with greater parenting stress and low social support.

Comments on the original article, "Setting free the bears: Escape from thought suppression," by D. M. Wegner (see record 2011-25622-008). While Wegner supposed that we might have to learn to live with bad thoughts, the present author discusses the use of imagination and guided imagery as an alternative to forced thought suppression.
The paper offers a critique of bizarreness studies that compare dreams to real world probability ratios and directed thought processes as a basis for determining the degree of bizarreness in dreams. It examines two cases from the literature and suggests that dreams are better compared to non-directed, or imaginative waking thought processes, specifically Inner Thought and Speech (or “speech for
For reasons internal to the concepts of thought and causality, a series of representations must be semantics-driven if that series is to add up to a single, unified thought. Where semantics is not operative, there is at most a series of disjoint representations that add up to nothing true or false, and therefore do not constitute a thought at all.

This study utilizes a prospective design to examine the interaction of recent rape/attempted rape with individual differences in thought suppression on increases in disordered eating symptoms during late adolescence/emerging adulthood. Thought suppression is the attempt to suppress unwanted thoughts. We propose that emerging adult women who have experienced recent rape/attempted rape and tend to use thought suppression as a coping mechanism are at risk for increases in disordered eating. 319 women completed the Eating Disorder Examination Questionnaire, the Sexual Experiences Survey, the Childhood Trauma Questionnaire, and the White Bear Thought Suppression Inventory in their first month of college and three months later. The experience of recent rape/attempted rape in the three months prior to the assessment accounted for unique variance in disordered eating at Time 2. Levels of thought suppression assessed at Time 1 significantly moderated the influence of recent rape/attempted rape on disordered eating at Time 2. PMID:24439617

The connected member of the impeller is coupled with the ring gear of the dual planetary gear of the dual planetary gear unit is made to be and ring gear of the dual planetary gear unit is made to be restrained as required, and the carrier is coupled with an output member.
This module provides a strategy for determining whether a written questionnaire is an appropriate means of gathering data to meet the goals of an evaluation. The authors define which conditions are suitable for using questionnaires.
During the survey, respondents are asked to provide qualitative answers (well, adequate, needs improvement) on how well material control and accountability (MC&A) functions are being performed. These responses can be used to develop failure probabilities for basic events performed during routine operation of the MC&A systems. The failure frequencies for individual events may be used to estimate total system effectiveness using a fault tree in a probabilistic risk analysis (PRA). Numeric risk values are required for the PRA fault tree calculations that are performed to evaluate system effectiveness. So, the performance ratings in the questionnaire must be converted to relative risk values for all of the basic MC&A tasks performed in the facility. If a specific material protection, control, and accountability (MPC&A) task is being performed at the 'perfect' level, the task is considered to have a near zero risk of failure. If the task is performed at a less than perfect level, the deficiency in performance represents some risk of failure for the event. As the degree of deficiency in performance increases, the risk of failure increases. If a task that should be performed is not being performed, that task is in a state of failure. The failure probabilities of all basic events contribute to the total system risk. Conversion of questionnaire MPC&A system performance data to numeric values is a separate function from the process of completing the questionnaire. When specific questions in the questionnaire are answered, the focus is on correctly assessing and reporting, in an adjectival manner, the actual performance of the related MC&A function. Prior to conversion, consideration should not be given to the numeric value that will be assigned during the conversion process. In the conversion process, adjectival responses to questions on system performance are quantified based on a log normal scale typically used in human error analysis (see A.D. Swain and H.E. Guttmann, 'Handbook of Human Reliability Analysis with Emphasis on Nuclear Power Plant Applications,' NUREG/CR-1278). This conversion produces the basic event risk of failure values required for the fault tree calculations. The fault tree is a deductive logic structure that corresponds to the operational nuclear MC&A system at a nuclear facility. The conventional Delphi process is a time-honored approach commonly used in the risk assessment field to extract numerical values for the failure rates of actions or activities when statistically significant data is absent.

The importance of individual differences in intelligence and working memory capacity in predicting the ability to intentionally suppress thoughts was investigated. Sixty participants completed a thought suppression task, and measures of working memory capacity (OSPAN), fluid intelligence (Raven’s Matrices), and crystallised intelligence (the National Adult Reading Test). As predicted, the results indicated that more effective thought suppression was independently related
Genuine, specific, timely emotional support of caregivers at the time of euthanasia is an important part of the veterinary professional obligation. Such support helps ease client pain during the grieving process. However, caution and sensitivity are essential when assessing and responding to caregiver-companion animal relationships.(1) For example, some caregivers are highly bonded but conceal their emotions, so our perceptions and responses must be thoughtful and discerning. My veterinary technician and I are supportive of our clients during euthanasia. I later write the condolence letter according to our perceptions of that particular human-companion animal bond. The only exceptions to our attempt to be thoroughly supportive at the time of euthanasia are those instances when we perceive that there has been obvious and willful abuse or neglect. At such times, we try to maintain emotional neutrality. The condolence letter and its variations described here are intended to serve as a guide. We send the condolence letter to caregivers within 24 hours of euthanasia, and it is addressed to the entire family. In addition, a euthanasia packet is provided at the time of euthanasia. The packet includes 2 brochures on coping with the loss of a companion animal, (2,3) contact information for a pet loss support hotline and a pet loss support group, an essay and a poem about the death of a companion animal, and a how-to article on dealing with children and their emotions on the loss of a pet. (4) My veterinary technician almost always phones the caregiver 1 to 3 days after euthanasia of their companion animal. The timing of the call depends on the circumstances of death and our judgment as to the emotional needs of the caregiver and family. Where emotions around euthanasia and loss are especially deep, the follow-up call may be made as early as that night or the next morning, with a second call 2 to 3 days later. The nature of the conversation depends on the technician's perception of the caregiver's needs. A condolence letter should reflect the needs and values of the individual veterinarian. For example, McElyea includes a brief history or profile of the animal and a reminder that death was easy and without suffering. (5) Others may wish to send a separate condolence to a child who seems especially affected by the death and loss of their special friend. I hope this article will encourage colleagues to hand-write condolence letters that reflect positive personal thoughts and feelings about the patient, the client, and the circumstances of the loss.

Virtually all scenarios on Solar System development ignore Mercury, but such inattention is probably undeserved. Once viable lunar and (probably) asteroidal facilities are established in the next century, Mercury warrants further investigation. Mercury's high solar energy density is a major potential advantage for space-based industries. Indeed, despite its higher gravity, Mercury is roughly twice as easy to leave as the Moon if the additional solar flux is taken into account. Moreover, with solar-driven technologies such as solar sails or electric propulsion, its depth in the Sun's gravity well is less important. Because Mercury is airless and almost certainly waterless, it will be an obvious place to export lunar technology, which will have been developed to deal with very similar conditions. Methods for extracting resources from anhydrous silicates will be particularly germane. Even without solar-powered propulsion, the discovery of low-delta-V access via multiple Venus and Earth encounters makes the planet easier to reach than had been thought. Technology developed for multi-year missions to asteroids and Mars should be readily adaptable to such Mercurian missions. Mercury will not be our first outpost in the Solar System. Nonetheless, as facilities are established in cis-Earth space, it probably merits attention as a next step for development.

Formal thought disorder (FTD) has been associated with abnormalities in the semantic memory system. However, it is still unclear whether these abnormalities are related to the organization of the semantic system, or to the automatic spread of activation-inhibition in semantic networks. In this paper these alternative proposals are examined. Schizophrenic patients and healthy matched controls were given two semantic memory

An automatic transmission with four forward speeds and one reverse position, is described which consists of: an input shaft; an output member; first and second planetary gear sets each having a sun gear, a ring gear and a carrier supporting a pinion in mesh with the sun gear and ring gear; the carrier of the first gear set, the ring gear of the second gear set and the output member all being connected; the ring gear of the first gear set connected to the carrier of the second gear set; a first clutch means for selectively connecting the input shaft to the sun gear of the first gear set, including friction elements, a piston selectively engaging the friction elements and a fluid servo in which hydraulic fluid is selectively supplied to the piston; a second clutch means for selectively connecting the input shaft to the sun gear of the second gear set a third clutch means for selectively connecting the input shaft to the carrier of the second gear set including friction elements, a piston selectively engaging the friction elements and a fluid servo in which hydraulic fluid is selectively supplied to the piston; a first drive-establishing means for selectively preventing rotation of the ring gear of the first gear set and the carrier of the second gear set in only one direction and, alternatively, in any direction; a second drive-establishing means for selectively preventing rotation of the sun gear of the second gear set; and a drum being open to the first planetary gear set, with a cylindrical intermediate wall, an inner peripheral wall and outer peripheral wall and forming the hydraulic servos of the first and third clutch means between the intermediate wall and the inner peripheral wall and between the intermediate wall and the outer peripheral wall respectively.
A methodology for automatic mathematical modeling is described. The major objective is to create a very friendly environment for engineers to design, maintain and verify their model and also automatically convert the mathematical model into FORTRAN code for conventional computation. A demonstration program was designed for modeling the Space Shuttle Main Engine simulation mathematical model called Propulsion System Automatic Modeling (PSAM). PSAM provides a very friendly and well organized environment for engineers to build a knowledge base for base equations and general information. PSAM contains an initial set of component process elements for the Space Shuttle Main Engine simulation and a questionnaire that allows the engineer to answer a set of questions to specify a particular model. PSAM is then able to automatically generate the model and the FORTRAN code. A future goal is to download the FORTRAN code to the VAX/VMS system for conventional computation.
SUMMARY In three studies, we examined memories for previous recall. In Studies 1 and 2, undergraduates were asked whether they had vivid memories about various childhood events. After a one-hour (Study 1) or 2-week (Study 2) interval, they completed a second questionnaire containing new, but also previously presented childhood items. Participants estimated how recently they had thought about old and

Purpose The aim of this study was to analyze the relationships among thought–shape fusion (TSF), specific instruments to assess body image disturbances, and body image quality of life in eating disorder patients in order to improve the understanding of the links between body image concerns and a specific bias consisting of beliefs about the consequences of thinking about forbidden foods. Patients and methods The final sample included 76 eating disorder patients (mean age 20.13 ± 2.28 years; 59 women and seven men). After having obtained informed consent, the following questionnaires were administered: Body Appreciation Scale (BAS), Body Image Quality of Life Inventory (BIQLI-SP), Body Shape Questionnaire (BSQ), Eating Disorders Inventory-2 (EDI-2), State-Trait Anxiety Inventory (STAI), Symptom Checklist-90-Revised (SCL-90-R) and Thought-Shape Fusion Questionnaire (TSF-Q). Results Significant correlations were found between TSF-Q and body image-related variables. Those with higher scores in TSF showed higher scores in the BSQ (P < 0.0001), Eating Disorder Inventory – Drive for Thinness (EDI-DT) (P < 0.0001), and Eating Disorder Inventory – Body Dissatisfaction (EDI-BD) (P < 0.0001). The same patients showed lower scores in the BAS (P < 0.0001). With respect to the psychopathological variables, patients with high TSF obtained higher scores in all SCL-90-R subscales as well as in the STAI. Conclusion The current study shows the interrelations among different body image-related variables, TSF, and body image quality of life.
Spontaneous thoughts, the output of a broad category of uncontrolled and inaccessible higher order mental processes, arise frequently in everyday life. The seeming randomness by which spontaneous thoughts arise might give people good reason to dismiss them as meaningless. We suggest that it is precisely the lack of control over and access to the processes by which they arise that leads people to perceive spontaneous thoughts as revealing meaningful self-insight. Consequently, spontaneous thoughts potently influence judgment. A series of experiments provides evidence supporting two hypotheses. First, we hypothesize that the more a thought is perceived to be spontaneous, the more it is perceived to provide meaningful self-insight. Participants perceived more spontaneous kinds of thought (e.g., intuition) to reveal greater self-insight than did more controlled kinds of thought in Study 1 (e.g., deliberation). In Studies 2 and 3, participants perceived thoughts with the same content and target to reveal greater self-insight when spontaneously rather than deliberately generated (i.e., childhood memories and impressions formed). Second, we hypothesize that the greater self-insight attributed to thoughts that are (perceived to be) spontaneous leads those thoughts to more potently influence judgment. Participants felt more sexually attracted to an attractive person whom they thought of spontaneously than deliberately in Study 4, and reported their commitment to a current romantic relationship would be more affected by the spontaneous rather than deliberate recollection of a good or bad experience with their romantic partner in Study 5.

Verbal thoughts (such as negative cognitions) and sensory phenomena (such as visual mental imagery) are usually conceptualised as distinct mental experiences. The present study examined to what extent depressive thoughts are accompanied by sensory experiences and how this is associated with symptom severity, insight of illness and quality of life. A large sample of mildly to moderately depressed patients (N = 356) was recruited from multiple sources and asked about sensory properties of their depressive thoughts in an online study. Diagnostic status and symptom severity were established over a telephone interview with trained raters. Sensory properties of negative thoughts were reported by 56.5% of the sample (i.e., sensation in at least one sensory modality). The highest prevalence was seen for bodily (39.6%) followed by auditory (30.6%) and visual (27.2%) sensations. Patients reporting sensory properties of thoughts showed more severe psychopathological symptoms than those who did not. The degree of perceptuality was marginally associated with quality of life. The findings support the notion that depressive thoughts are not only verbal but commonly accompanied by sensory experiences. The perceptuality of depressive thoughts and the resulting sense of authenticity may contribute to the emotional impact and pervasiveness of such thoughts, making them difficult to dismiss for their holder.

With the use of computers, paper questionnaires are being replaced by electronic questionnaires. The formats of traditional paper questionnaires have been found to effect a subject's rating. Consequently, the transition from paper to electronic format can subtly change results. The research presented begins to determine how electronic questionnaire formats change subjective ratings. For formats where subjects used a flow chart to arrive at their rating, starting at the worst and middle ratings of the flow charts were the most accurate but subjects took slightly more time to arrive at their answers. Except for the electronic paper format, starting at the worst rating was the most preferred. The paper and electronic paper versions had the worst accuracy. Therefore, for flowchart type of questionnaires, flowcharts should start at the worst rating and work their way up to better ratings.
Our sense of self includes awareness of our thoughts and movements, and our control over them. This feeling can be altered or lost in neuropsychiatric disorders as well as in phenomena such as "automatic writing" whereby writing is attributed to an external source. Here, we employed suggestion in highly hypnotically suggestible participants to model various experiences of automatic writing during a sentence completion task. Results showed that the induction of hypnosis, without additional suggestion, was associated with a small but significant reduction of control, ownership, and awareness for writing. Targeted suggestions produced a double dissociation between thought and movement components of writing, for both feelings of control and ownership, and additionally, reduced awareness of writing. Overall, suggestion produced selective alterations in the control, ownership, and awareness of thought and motor components of writing, thus enabling key aspects of automatic writing, observed across different clinical and cultural settings, to be modelled.

An anonymous survey to assess the attitudes to smoking of men serving on two Trident Nuclear submarines was conducted by questionnaire. A total of 244 questionnaires were completed, representing 87% of the two crews. Thirty-two percent of respondents declared themselves to be smokers, 69% were nonsmokers, and of these, 31% were ex-smokers. Attitudes of all respondents to an enforced ban of smoking on submarines indicated that 55% felt that it would be justifiable, 46% felt that it would be unfair, 42% felt that it was uncalled for, 46% thought that it would be illegal, and 47% thought that a ban was about time. The separate opinions of smokers and nonsmokers were polarized, whereas the overall results indicate indifferent attitudes of crew members. Further research into the atmospheric effects of environmental tobacco smoke on a submarine is required. PMID:12125854
Recent studies indicate that human locomotion is quadrupedal in nature. An automatic rhythm-generating system is thought to play a crucial role in controlling arm and leg movements. In the present study, we attempted to elucidate differences between intrinsic arm and leg automaticity by investigating cadence variability during simultaneous arm and leg (AL) cycling. Participants performed AL cycling with visual feedback of arm or leg cadence. Participants were asked to focus their attention to match the predetermined cadence; this affects the automaticity of the rhythm-generating system. Leg cadence variability was only mildly affected when the participants intended to precisely adjust either their arm or leg cycling cadence to a predetermined value. In contrast, arm cadence variability significantly increased when the participants adjusted their leg cycling cadence to a predetermined value. These findings suggest that different neural mechanisms underlie the automaticities of arm and leg cycling and that the latter is stronger than the former during AL cycling. PMID:24548625

While goal-directed thinking has received the lion's share of neuroscientific attention, its counterpart--the undirected thought flow that comes to mind unbidden and without effort--has remained largely on the sidelines of scientific research. Such undirected thought, however, forms a large part of our mental experience. The last decade of neuroscientific investigations marked a resurgence of interest and work into the neural basis of undirected thought. This article reviews the current status of the field and examines the research on the three most frequently discussed categories of undirected thought: spontaneous thought, stimulus-independent thought, and mind wandering. The terminology and paradigms for investigating undirected thought are still being developed, while research is gradually moving beyond strictly task- and rest-based paradigms and towards incorporating introspective first-person reports in order to better understand this phenomenon. It is impossible to say at this point that undirected thinking is preferentially linked to any one particular brain system. Although its connection to the default network has been disproportionately emphasized in the literature, other brain networks such as the executive system and the temporal lobe memory network appear to be equally involved. In addition to reviewing the literature, this article also presents novel findings regarding the functional connectivity between large-scale brain networks during mind wandering. These findings reveal the presence of positive functional connectivity between regions of the default and executive networks and negative functional connectivity between the default network and primary sensory cortices. Thus, the default and executive networks can closely cooperate in supporting undirected thought processes, and seem to do so at times when the primary sensory cortices are not busy with the processing of perceptual information from the external environment. This article is part of a Special Issue entitled The Cognitive Neuroscience of Thought. PMID:22071565

The relation between cognitive self-consciousness and meta-worry, and their association with symptoms of worry and obsessional thoughts were examined. 53 undergraduate students completed the expanded version of the Cognitive Self-consciousness Scale, the Meta-worry subscale of the Anxious Thoughts Inventory, the Penn State Worry Questionnaire, and the Padua Inventory-Revised. Analysis showed that cognitive self-consciousness and meta-worry were moderately correlated (r =.57). Further, both constructs were positively associated with symptoms of worry and obsessional thoughts. When controlling for cognitive self-consciousness, metaworry remained significantly correlated to both types of symptoms. Yet, when controlling for meta-worry, correlations between cognitive self-consciousness and symptoms of worry and obsessional thoughts clearly attuned and were no longer significant. These findings suggest that meta-worry is more important for understanding excessive, intrusive thought patterns than the mere tendency to monitor one's thoughts. PMID:15825931

The data needs questionnaire is an element in the project design study for the Michigan Resource Inventory Act and is aimed at gathering information on what inventory information is required by land use planners throughout the state. Analysis of questionnaire responses is discussed. Some information on current use categories was tabulated. The respondents selected a broad range of categories at all levels of detail. Those most frequently indicated were urban categories.
The questionnaire is the instrument used for recording performance data on the nuclear material protection, control, and accountability (MPC&A) system at a nuclear facility. The performance information provides a basis for evaluating the effectiveness of the MPC&A system. The goal for the questionnaire is to provide an accurate representation of the performance of the MPC&A system as it currently exists in the facility. Performance grades for all basic MPC&A functions should realistically reflect the actual level of performance at the time the survey is conducted. The questionnaire was developed after testing and benchmarking the material control and accountability (MC&A) system effectiveness tool (MSET) in the United States. The benchmarking exercise at the Idaho National Laboratory (INL) proved extremely valuable for improving the content and quality of the early versions of the questionnaire. Members of the INL benchmark team identified many areas of the questionnaire where questions should be clarified and areas where additional questions should be incorporated. The questionnaire addresses all elements of the MC&A system. Specific parts pertain to the foundation for the facility's overall MPC&A system, and other parts pertain to the specific functions of the operational MPC&A system. The questionnaire includes performance metrics for each of the basic functions or tasks performed in the operational MPC&A system. All of those basic functions or tasks are represented as basic events in the MPC&A fault tree. Performance metrics are to be used during completion of the questionnaire to report what is actually being done in relation to what should be done in the performance of MPC&A functions.

Suppression of negative thoughts has been observed under experimental conditions among patients with major depressive disorder (MDD) but has never been examined among patients with bipolar disorder (BD). Patients with BD (n = 36), patients with MDD (n = 20), and healthy controls (n = 20) completed a task that required unscrambling 6-word strings into 5-word sentences, leaving out 1 word. The extra word allowed the sentences to be completed in a negative, neutral, or “hyperpositive” (manic/goal-oriented) way. Participants completed the sentences under conditions of cognitive load (rehearsing a 6-digit number), reward (a bell tone), load and reward, or neither load nor reward. We hypothesized that patients with BD would engage in more active suppression of negative and hyperpositive thoughts than would controls, as revealed by their unscrambling more word strings into negative or hyperpositive sentences. Under conditions of load or reward and in the absence of either load or reward, patients with BD unscrambled more negative sentences than did controls. Under conditions of reward, patients with BD unscrambled more negative sentences than did patients with MDD. Patients with BD also reported more use of negative thought suppression than did controls. These group differences in negative biases were no longer significant when current mood states were controlled. Finally, the groups did not differ in the proportion of hyperpositive sentence completions in any condition. Thought suppression may provide a critical locus for psychological interventions in BD.

Since the end of World War II, the United States has faced moral and strategic issues in its management of force that are unique in the history of international politics. At the heart of these issues is the heavy reliance of the United States and its allies on the deterrent effect of nuclear weapons and the fact that their use would very likely lead to self-defeating destruction and ecological catastrophe. This dilemma affects every major military decision and strategic debate, and the history of U.S. strategic thought can be viewed as an attempt to cope by rejecting, abolishing, or weakening the nuclear specter. In this review, the author explores the evolution of postwar strategic thought in the United States, examining the moral and practical implications of the nuclear dilemma.
Fear of suffocation and fear of restriction are thought to underlie claustrophobia and can be assessed with the Claustrophobia Questionnaire (CLQ; Radomsky et al., 2001). A first study tested the psychometric properties of a Dutch version of the CLQ. Students (N=363) completed a Dutch translation of the CLQ and a set of other questionnaires assessing other specific fears, anxiety or depression. Results confirmed the two-factor structure and showed that the Dutch version of the CLQ has good psychometric properties. A second study tested the predictive validity of the Dutch CLQ. Participants (N=23) were exposed each to nine claustrophobic situations with elements of suffocation, restriction or both. The Dutch CLQ was found to be a significant predictor of fear and respiratory reactivity during claustrophobic exposure. It can be concluded that the Dutch version of the CLQ is a reliable and valid instrument to assess claustrophobic fear. PMID:20558033

SUMMARY 15 schizophrenic patients were treated with dl-propranolol in a 4 week open study. Dosage was gradually increased over a period of 17 days to 1920 mg/day. Improvements were rated on Thought Disorder Scores (A & B) of the MBPRS and GPRS subscale for schizophrenia. Majority of the patients showed a 50% improvement in terms of their residual scores by the 4th week of treatment and the side effects experienced were minimal.
\\u000a This chapter offers a brief overview of the differing schools of thought related to criminal profiling. As discussed in this\\u000a chapter, there currently appears to be three distinct approaches that operate under the respective titles of Criminal Investigative\\u000a Analysis, Investigative Psychology, and Crime Action Profiling. The central ideological tenets and methodological characteristics\\u000a underpinning and differentiating each are briefly outlined.
Chinese democratization is usually thought of as a top-down process sponsored by a reform-minded government and liberal intellectuals. At the turn of the millennium, however, no such development is in sight. Only recently have Western scholars begun to look to the countryside for finding ‘sprouts of democracy’. This study explores village self-government as a possibility of making local political practices

Obesity surgery is the most effective treatment method for the severely obese but does not work for everyone. Indications are that weight-loss success may be related to individuals' sense of investment in surgery, with failure linked to higher automatic hedonic motivations to consume food and greater susceptibility to food in the environment. A pilot study using an independent experimental design recruited bariatric surgery patients (n = 91) via a UK obesity-surgery charity website who were randomly allocated to either the intervention or the control condition. The intervention involved raising the salience of the personal investment made in having weight-loss surgery in an attempt to reduce automatic hedonic thoughts about food and aid weight loss. Data was collected initially with subsequent weight loss measured at 3 months of follow-up. Following the intervention, participants reported significantly reduced hedonic thoughts, increased liking for low-fat foods, reduced liking of high-fat food, and higher self-efficacy for achieving sustained weight loss than controls. By 3 months, this was translated into significant differences in mean weight losses of 6.77?kg for the intervention group and 0.91?kg for control participants. To conclude, a quick simple cost-effective intervention encouraging participants to focus on investment helped weight loss and changed hedonic thoughts about food in bariatric patients.

After a brief description of the principal findings which emerge from the studies on expressed emotion (EE), the author puts forward a few critical thoughts based on a systemic orientation. He explains why the variable EE evaluated on the basis of the Camberwell Family Interview (CFI) does not sufficiently reflect the dynamic reality of the family interactions and, in particular, he criticizes the establishment of a linear causality relationship between family EE and the development of the individual illness. He shows the limitations of psycho-educational programmes while acknowledging their place in the overall supportive family therapies. PMID:6537539
Universe: A Thought Symphony, recasting the last, most ambitious, yet uncomplicated composition, Universe Symphony of American composer Charles Ives, we will match it with a new libretto derived from selections of Teilhard de Chardin's Hymn of the Universe and George V. Coyne, S.J. and Alessandro Omizzolo's Wayfarers In the Cosmos. The piece (running time 37 minutes), has three movements: Past-moving from Chaos, the formation of the waters and mountains; Present-the formation of the Earth and the firmament, evolution in nature and humanity; and Future-the rise of all beyond.

Objective. To further evaluate the adequacy of the items in our questionnaire aimed at unraveling the possible correlations between psychological features and internal disorders. This paper is dedicated to the items exploring the individual’s interaction with other people. Method. The items are divided into several subdomains. For each subdomain, we have calculated the correlations between the items of the respective subdomain (inner associations) and with the items in other subdomains (outer associations) by means of chi square test or Fisher exact test as dictated by statistical reasons. We examined the answers from our first 10192 respondents. Results and conclusions. Many inter-item correlations are the consequence of higher or lesser degrees of synonymy. Those within a given subdomain confirm the adequate allocation of items. Those bridging different subdomains may point either to incorrect assignments, or to semantic inclusion relations. Other results are not explicable by semantic similarity, and probably reveal psychological subtleties, such as: most individuals have a sense of undeservedness when badly treated by other people; those easily hurt by insults and humiliations have a propensity to timidity and/or emotivity; the subjects who shun conflicts are more prone to persistent thoughts, brooding people are more sensitive and more prone to conflicts, injustice-indignant people frequently get into conflict although they declare to be bothered by dissent etc. But at the heart of all the PFs in the Interaction-with-other-people domain there seems to be the sense of being undervalued, which should probably be the key issue to be addressed by any therapeutic interventions for diseases psychoemotionally determined by disturbed interpersonal relationships.

Purpose To determine if respondents share researchers’ understandings of concepts and questions frequently used in the assessment of usual physical activity behavior. Methods As part of On the Move, a study aimed at reducing measurement error in self-reported physical activity (PA), we conducted cognitive interviews with 19 men and 21 women, ages 45-65, regarding their responses to the PA questionnaires used in two large, population-based studies, LACE (Life After Cancer Epidemiology) and CMH (California Men’s Health Study). One questionnaire asks about the frequency, duration, and perceived intensity of a range of specific activities in several different domains over the past 12 months. The second questionnaire asks about frequency and duration of specific, mostly recreational activities, grouped by intensity (i.e., moderate or vigorous) over the past 3 months. We used verbal probing techniques to allow respondents to describe their thought processes as they completed the questionnaires. All interviews were tape-recorded and transcribed, and the transcripts were then analyzed using standard qualitative methods. Results Cognitive interviews demonstrated that a sizable number of respondents understood “intensity” in terms of emotional or psychological intensity, rather than physical effort. As a result, the perceived intensity with which a participant reported doing a specific activity often bore little relationship to the MET value of that activity. Additionally, participants often counted the same activity more than once, overestimated work-related PA, and understood activities that were grouped together in a single category to be definitive lists rather than examples. Conclusion Cognitive interviews revealed significant gaps between respondents’ interpretations of some physical activity questions and researchers’ assumptions about what those questions were intended to measure. Some sources of measurement error in self-reported PA may be minimized by additional research that focuses on the cognitive processes required to respond to PA questionnaires.

This paper is concerned with automatic segmentation of high resolution digitized metaphases. This includes automatic detection and rejection of interphase nuclei, stain debris, and other "noise"; automatic detection and segmentation of touching and overlapping chromosome clusters; and automatic rejection of cells which are evaluated as being incomplete, or incorrectly segmented, or where the cell is otherwise unsuitable for further analysis. In this paper, a rule-based approach is described which treats the cell as a whole rather than as a series of individual chromosomes or clusters. The rules adapt classification and segmentation parameters for each cell. Initially, different sets of parameters are chosen according to the staining method of the cells, and the goal of the segmentation. A chromosome number predictor is used to guide the adaptation of the parameters and to estimate the performance. The adaptation is iterative, and the self-adjustment will stop when either a satisfactory result is achieved or if the cell is rejected. The method was implemented on both a Sun workstation and a Cytoscan, a commercial machine for chromosome analysis. Seven hundred and thirteen cells from real data have been tested. A success rate of 90-95% has been achieved. The procedure has been implemented in an automatic aberration scoring system for routine use. PMID:7851156
Acceptance and Commitment Therapy (ACT) emphasizes the relationship a person has with their thoughts and beliefs as potentially more relevant than belief content in predicting the emotional and behavioral consequences of cognition. In ACT, "defusion" interventions aim to "unhook" thoughts from actions and to create psychological distance between a person and their thoughts, beliefs, memories, and self-stories. A number of similar concepts have been described in the psychology literature (e.g., decentering, metacognition, mentalization, and mindfulness) suggesting converging evidence that how we relate to mental events may be of critical importance. While there are some good measures of these related processes, none of them provides an adequate operationalization of cognitive fusion. Despite the centrality of cognitive fusion in the ACT model, there is as yet no agreed-upon measure of cognitive fusion. This paper presents the construction and development of a brief, self-report measure of cognitive fusion: The Cognitive Fusion Questionnaire (CFQ). The results of a series of studies involving over 1,800 people across diverse samples show good preliminary evidence of the CFQ's factor structure, reliability, temporal stability, validity, discriminant validity, and sensitivity to treatment effects. The potential uses of the CFQ in research and clinical practice are outlined. PMID:24411117

Quantitative mapping of structural and functional connectivities in the human brain via non-invasive neuroimaging offers an exciting and unique opportunity to understand brain architecture. Because connectivity alterations are widely reported in a variety of brain diseases, assessment of structural and functional connectivities has emerged as a fundamental research area in clinical neuroscience. A fundamental question arises when attempting to map structural and functional connectivities: how to define and localize the best possible Regions of Interests (ROIs) for brain connectivity mapping? Essentially, when mapping brain connectivities, ROIs provide the structural substrates for measuring connectivities within individual brains and for pooling data across populations. Thus, identification of reliable, reproducible and accurate ROIs is critically important for the success of brain connectivity mapping. This paper discusses several major challenges in defining optimal brain ROIs from our perspective and presents a few thoughts on how to deal with those challenges based on recent research work done in our group.
Recent research suggested that the super-eruption of the Campi Flegrei caldera volcano in southern Italy about 40,000 years ago may have played a part in wiping out, or forcing the migration of, the Neanderthal and modern human populations in the eastern Mediterranean regions that were covered in ash. Now a new modeling study by Costa et al. suggests that this eruption may have been even larger than previously thought. This Campi Flegrei eruption produced a widespread ash layer known as Campanian Ignimbrite (CI). Using ash thickness measurements collected at 115 sites and a three-dimensional ash dispersal model, the researchers found that the CI super-eruption would have spread 250-300 cubic kilometers of ash across a 3.7-million-square kilometer region—2 to 3 times previous ash volume estimates.
This paper presents a real-time electro-encephalogram (EEG) identification system with the goal of achieving hands free control. With two EEG electrodes placed on the scalp of the user, EEG signals are amplified and digitised directly using a ProComp+ encoder and transferred to the host computer through the RS232 interface. Using a real-time multilayer neural network, the actual classification for the control of a powered wheelchair has a very fast response. It can detect changes in the user's thought pattern in 1 second. Using only two EEG electrodes at positions O(1) and C(4) the system can classify three mental commands (forward, left and right) with an accuracy of more than 79 % PMID:17946455
Being happy or sad influences the content and style of thought. One explanation is that affect serves as information about the value of whatever comes to mind. Thus, when a person makes evaluative judgments or engages in a task, positive affect can enhance evaluations and empower potential responses. Rather than affect itself, the information conveyed by affect is crucial. Tests of the hypothesis find that affective influences can be made to disappear by changing the source to which the affect is attributed. In tasks, positive affect validates and negative affect invalidates accessible cognitions, leading to relational processing and item-specific processing, respectively. Positive affect is found to promote, and negative affect to inhibit, many textbook phenomena from cognitive psychology.

We are using automatic photoelectric telescopes at the Tennessee State University Center for Automated Space Science to search for planets around nearby stars in our galaxy. Over the past several years, wc have developed the capability to make extremely precise measurements of brightness changes in Sun-like stars with automatic telescopes. Extensive quality control and calibration measurements result in a precision of 0.l% for a single nightly observation and 0.0270 for yearly means, far better than previously thought possible with ground-based observations. We are able, for the first time, to trace brightness changes in Sun-like stars that are of similar amplitude to brightness changes in the Sun, whose changes can be observed only with space-based radiometers. Recently exciting discoveries of the first extrasolar planets have been announced, based on the detection of very small radial-velocity variations that imply the existence of planets in orbit around several Sun-like stars. Our precise brightness measurements have been crucial for the confirmation of these discoveries by helping to eliminate alternative explanations for the radial-velocity variations. With our automatic telescopes, we are also searching for transits of these planets across the disks of their stars in order to conclusively verify their existence. The detection of transits would provide the first direct measurements of the sizes, masses, and densities of these planets and, hence, information on their compositions and origins.
Human minds often engage in thoughts and feelings that are self-generated rather than stimulus-dependent, such as daydreaming. Recent research suggests that under certain circumstances, daydreaming is associated with adverse effects on cognition and affect. Based on recent literature about the influence of resting mind in relation to rumination and depression, this questionnaire study investigated mechanisms linking daydreaming to depressive symptoms. Specifically, an indirect effect model was tested in which daydreaming influences depressive symptoms through enhancing self-focus and ruminative thought. Results were in line with the hypothesis and several alternative pathways were ruled out. The results provide initial supportive evidence that daydreaming can influence depressive symptoms through influences on self-focus and rumination. Further research should use prospective or experimental designs to further validate and strengthen these conclusions.

The purpose of this paper is to summarize the development and testing of the Norbeck Social Support Questionnaire (NSSQ) and to discuss several issues that have arisen in recent use of the instrument. The NSSQ is a self-administered questionnaire that measures multiple dimensions of social support. Three functional properties--affect, affirmation, and aid--from Kahn's (1979) definition of social support are measured. The network properties of size, stability (duration of relationships), and accessibility (frequency of contact) are also measured, as well as changes in the convoy or support system due to losses of relationships. Nine categories are used to determine sources of support. Graduate students of nursing (N = 130) were used as subjects for several studies to test reliability and validity, and employed adults (N = 136) were used for additional validity testing and to provide normative data. Reliability was established through analysis of internal consistency and test-retest measures taken a week apart. Very high levels of internal consistency and test-retest reliability were found for the functional and network properties, and medium levels for the loss items. At a 7-month retesting, medium levels of stability were found, and the instrument was sensitive to changes in the network composition over time. Although the network composition changed, the overall level of functional support remained stable. Validity of the NSSQ was tested in relation to response bias and concurrent, construct, and predictive validity. The results indicated that the instrument is free from the response bias of social desirability. Medium levels of concurrent validity were shown with two other social support instruments. Construct validity was demonstrated by significant associations between NSSQ measures and two interpersonal constructs expected to be related to social support, while no significant relationships were found between the NSSQ measures and an unrelated interpersonal construct. Predictive validity was tested by examining the hypothesis that social support serves as a buffer for life stress. Among the functional properties, the interaction of aid and life stress accounted for 13.2% of the variance in negative mood. Of the network properties, duration of relationships had significant main and interaction effects, accounting together for 19.3% of the variance in negative mood. Normative data from a sample of employed adults provide means and standard deviations for each subscale and variable of the NSSQ, as well as descriptive data about sources of support.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:6536338
A questionnaire is a method for collecting data that can come from many sources such as observations, telephone interviews or documentary sources. Whatever the source of data is, the questionnaire provides a framework of questions that facilitate researcher's work. A manual approach for collecting data using questionnaire presents some limitations and introduces several sources of errors. A second issue regards the statistical and data mining of data that often is conducted using different tools than the questionnaire system, which may introduce errors in the analysis pipeline. For instance, common methods applied to data set concern the normality test, the association and correlation discovery, linear regression, classification and clustering. Usually this analysis is performed using external tools, often not free, such as SPSS, SAS, STATA, Weka, or Clementine.We present a web-based software system, to automatize the analysis pipeline and to support researchers involved in the collection of questionnaire data, such as in epidemiology, aiming to reduce the errors listed above and including some basic functions to conduct statistical analysis on collected data. Our system allows researchers to create questionnaires, adding sections and structured questions. It provides a preview of the questionnaire, the exportation of saved data into statistical software compatible formats, or it permits to analyze them directly applying statistical methods and common data mining techniques from the main interface.

The current research investigates the interaction between thought suppression and individuals' explicit awareness of their thoughts. Participants in three experiments attempted to suppress thoughts of a prior romantic relationship and their success at doing so was measured using a combination of self-catching and experience-sampling. In addition to thoughts that individuals spontaneously noticed, individuals were frequently caught engaging in thoughts of their previous partner at experience-sampling probes. Furthermore, probe-caught thoughts were: (i) associated with stronger decoupling of attention from the environment, (ii) more likely to occur under cognitive load, (iii) more frequent for individuals with a desire to reconcile, and (iv) associated with individual differences in the tendency to suppress thoughts. Together, these data suggest that individuals can lack meta-awareness that they have begun to think about a topic they are attempting to suppress, providing novel insight into the cognitive processes that are involved in attempting to control undesired mental states.

Using a standardized schedule of questions, this study examined (a) the prevalence of self-report of violent thoughts by patients hospitalized for mental disorders compared with nonpatients, (b) the persistence of violent thoughts after discharge, and (c) the relation between patients' violent thoughts while hospitalized and violent acts within 20 weeks after hospital discharge. About 1/3 of the patients reported thoughts of violence while hospitalized, more than twice the proportion found among nonpatients. Reporting violent thoughts in hospital was significantly related to engaging in violent acts within 20 weeks after discharge for non-White patients, patients without major mental disorder but with substance abuse diagnoses, patients with high symptom severity, and patients whose reports of violent thoughts persisted after discharge. Reporting violent thoughts was significantly related to measures of psychopathy, anger, and impulsiveness. PMID:10883555

Mycobacterium microti is a member of the Mycobacterium tuberculosis complex of bacteria. This species was originally identified as a pathogen of small rodents and shrews and was associated with limited diversity and a much reduced spoligotype pattern. More recently, specific deletions of chromosomal DNA have been shown to define this group of organisms, which can be identified by the absence of chromosomal region RD1mic. We describe here the molecular characteristics of 141 strains of the Mycobacterium tuberculosis complex isolated in Great Britain over a 14-year period. All strains have characteristic loss of some spoligotype spacers and characteristic alleles at the ETR-E and ETR-F variable-number tandem-repeat (VNTR) loci, and a sample of these strains was deleted for regions RD7, RD9, and RD1mic but intact for regions RD4 and RD12. We therefore identified these strains as M. microti and show that they have much more diverse spoligotype patterns and VNTR types than previously thought. The most common source of these strains was domestic cats, and we show that the molecular types of M. microti are geographically localized in the same way that molecular types of Mycobacterium bovis are geographically localized in cattle in the United Kingdom. We describe the pathology of M. microti infection in cats and suggest that the feline disease is a spillover from a disease maintained in an unknown wild mammal, probably field voles. The location of the cats with M. microti infection suggests that they do not overlap geographically with the strains of Mycobacterium bovis in Great Britain.

Objectives Subjective questionnaires are informative in understanding the difficulties faced by patients with hearing loss. Our intent was to establish and validate a new questionnaire that encompasses situations emphasizing binaural hearing. The Spatial Hearing Questionnaire is a self-report assessment tool utilizing eight subscales representing questions pertaining to the perception of male, female, and children’s voices, music in quiet, source localization, understanding speech in quiet, and understanding speech in noise. Design The Spatial Hearing Questionnaire, composed of 24 items, is scored from 0–100. It was administered to 142 subjects using one or two cochlear implants. Speech perception and localization abilities were measured, and the Speech, Spatial and Other Qualities (SSQ) questionnaire was completed to evaluate validity of the questionnaire. Psychometric tests were done to test the reliability and factor structure of the Spatial Hearing Questionnaire. Results Results showed high internal consistency reliability (Cronbach’s ? = 0.98) and good construct validity (correlations between the Spatial Hearing Questionnaire and other test measures, including the SSQ, were significant). A preliminary factor analysis revealed scores loaded on three factors, representing the following conditions: localization, speech in noise and music in quiet, and speech in quiet, explaining 64.9, 13.0, and 5.3% of the variance, respectively. Most of the questionnaire items (12/24) loaded onto the first factor which represents the subscale related to source localization. Mean scores on the Spatial Hearing Questionnaire were higher for subjects with bilateral cochlear implants over subjects with a unilateral cochlear implant, consistent with other research and supporting construct validity. Conclusions The Spatial Hearing Questionnaire is a reliable and valid questionnaire which can be completed independently by most patients in about 10 minutes. It is likely to be a valuable tool for clinicians and researchers to measure spatial hearing abilities.
Great strides have been made in the development of automatic speech recognition (ASR) technology over the past thirty years. Most of this effort has been centered around the extension and improvement of Hidden Markov Model (HMM) approaches to ASR. Current commercially-available and industry systems based on HMMs can perform well for certain situational tasks that restrict variability such as phone dialing or limited voice commands. However, the holy grail of ASR systems is performance comparable to humans-in other words, the ability to automatically transcribe unrestricted conversational speech spoken by an infinite number of speakers under varying acoustic environments. This goal is far from being reached. Key to the success of ASR is effective modeling of variability in the speech signal. This tutorial will review the basics of ASR and the various ways in which our current knowledge of speech production, speech perception and prosody can be exploited to improve robustness at every level of the system.
This patent describes a method of controlling an automatic transmission of an automotive vehicle. The transmission has a gear train which includes a brake for establishing a first lowest speed of the transmission, the brake acting directly on a ring gear which meshes with a pinion, the pinion meshing with a sun gear in a planetary gear train, the ring gear connected with an output member, the sun gear being engageable and disengageable with an input member of the transmission by means of a clutch. The method comprises the steps of: detecting that a shift position of the automatic transmission has been shifted to a neutral range; thereafter introducing hydraulic pressure to the brake if present vehicle velocity is below a predetermined value, whereby the brake is engaged to establish the first lowest speed; and exhausting hydraulic pressure from the brake if present vehicle velocity is higher than a predetermined value, whereby the brake is disengaged.

A method is devised for the automatic detection of a human body. The method utilizes the near-infrared reflection bands of the skin of the human body as the identifying signature. Illumination of the body is provided by a near-infrared light source and the detection of the reflection bands. When each of the three detectors simultaneously register a signal of the proper reflection values, a coincident trigger circuit enables an indicator device which signifies a human body is detected.
The ability to precisely emplace stand-alone payloads in hostile territory has long been on the wish list of US warfighters. This type of activity is one of the main functions of special operation forces, often conducted at great danger. Such risk can be mitigated by transitioning the manual placement of payloads over to an automated placement mechanism by the use of the Automatic Payload Deployment System (APDS). Based on the Automatically Deployed Communication Relays (ADCR) system, which provides non-line-of-sight operation for unmanned ground vehicles by automatically dropping radio relays when needed, the APDS takes this concept a step further and allows for the delivery of a mixed variety of payloads. For example, payloads equipped with a camera and gas sensor in addition to a radio repeater, can be deployed in support of rescue operations of trapped miners. Battlefield applications may include delivering food, ammunition, and medical supplies to the warfighter. Covert operations may require the unmanned emplacement of a network of sensors for human-presence detection, before undertaking the mission. The APDS is well suited for these tasks. Demonstrations have been conducted using an iRobot PackBot EOD in delivering a variety of payloads, for which the performance and results will be discussed in this paper.

To explore the role of the thought enhancement and thought rebound effects in obsessionality, the relationship between obsessional symptomology and responding during and after the attempted suppression of unpleasant personal intrusive thoughts was examined. Ss first completed the Maudsley Obsessive Compulsive Inventory (MOCI) [Rachman and Hodgson, 1980]. Later, Ss indicated their most frequent intrusive thought and then completed a thought suppression protocol in which they first expressed, then suppressed, and, again, expressed that thought. Ss' scores on the MOCI were examined in relation to their pattern of responding in the suppression protocol to investigate whether Ss who were higher in obsessionality were more prone to enhancement and/or rebound effects with an unpleasant personal intrusive thought than Ss who were lower in obsessionality. The following results were obtained: (1) there was a positive relationship between obsessionality levels and thought enhancement for female Ss; (2) there was a negative relationship between obsessionality levels and thought enhancement for male Ss; and (3) there was no relationship between obsessionality levels and thought rebound. These findings suggest that the rebound effect is unrelated to obsessionality and that the enhancement effect relationship to obsessionality may be more complex than previously hypothesized.

Jet contrails are an important subset of cirrus clouds in the atmosphere, and thin cirrus are thought to enhance the greenhouse effect due to their semi-transparent nature. They are nearly transparent to the solar energy reaching the surface, but they reduce the planetary emission to space due to their cold ambient temperatures. Having 'seeded' the environment, contrails often elongate and widen into cirrus-like features. However, there is great uncertainty regarding the impact of contrails on surface temperature and precipitation. With increasing numbers of subsonic aircraft operating in the upper troposphere, there is the possibility of increasing cloudiness which could lead to changes in the radiation balance. Automatic detection and seg- mentation of jet contrails in satellite imagery is important because (1) it is impractical to compile a contrail climatology by hand, and (2) with the segmented images it will be possible to retrieve contrail physical properties such as optical thickness, effective ice crystal diameter and emissivity.
A basic training in psychotherapy is a necessary requirement for the speciality of psychiatry. Nevertheless, any thorough training in psychotherapy in Greece lacks planning and a credible certification system. ?raining is carried out by different psychotherapeutic societies of varying prestige, through a number of programs. There have been very few attempts until now to map this field. The Section of Psychotherapy of the Hellenic Psychiatric Association (HPA) has tried to document the characteristics of the psychiatrists practicing psychotherapy. The study aimed at all of the trainee and trained psychiatrists, members of HPA. 210 questionnaires were filled in by members of HPA in 2000 and 2009-2011. Most of them were returned by post to the Section of Psychotherapy, while some were filled in during the 21rst HPA congress. With regard to psychotherapeutic training 151 (72%) reported some kind of psychoanalytic training, 90 (42.8%) cognitive, 85 (40.5%) systemic and 38 (18%) other (interpersonal, drama therapy, existentialist, cognitive-analytic, hypnosis, group therapy of another kind, orgonotherapy, vegetotherapy, Eye Movement Desensitization Reprocessing). The average duration of the training in years was 5.26 (±3.7) for the psychoanalytic one, 2.73 (±1.6) for the cognitive, 3.83 (±2.1) for the systemic and 3.08 (±2.5) for the psychiatrists with a different type of training. Interestingly, many of the participants reported more than one types of psychotherapeutic training. Another important finding is the fact that the range of training varies from a single seminar to many years, something which underlines the considerable divergence with regard to what is considered psychotherapeutic training. Several questions arise from the above findings: A first one is if a psychiatrist should, during his/her training, also be trained in psychotherapy and what kind of training this should be. A second question is if being a trained psychiatrist entails the capacity to practice psychotherapy and to be called a psychotherapist. Should the title of psychotherapist be a general one or should a specific theoretical-clinical approach be mentioned in the title (psychoanalyst, cognitive-behavioral, systemic, etc.). One more question is which institution is appropriate for the certification of a psychotherapist: a state authority or another, possibly private, institution such as scientific societies or Non-Governmental Organizations? A final question is where professionals from different fields certified as psychotherapists could converge and how their differences could be specified. The mapping and study of the field of psychotherapy within HPA can create the basis for a fruitful discussion on the issue of the psychiatrists' training and certification in psychotherapy, thus outlining a number of questions and dilemmas.

OBJECTIVE As use of standard depression questionnaires in clinical practice increases, clinicians will frequently encounter patients reporting thoughts of death or suicide. This study examined whether responses to the Patient Health Questionnaire for depression (PHQ-9) predict subsequent suicide attempt or suicide death. METHODS Electronic records from a large integrated health system were used to link PHQ-9 responses from outpatient visits to subsequent suicide attempts and suicide deaths. A total of 84,418 outpatients age ?13 completed 207,265 questionnaires between 2007 and 2011. Electronic medical records, insurance claims, and death certificate data documented 709 subsequent suicide attempts and 46 suicide deaths in this sample. RESULTS Cumulative risk of suicide attempt over one year increased from .4% among outpatients reporting thoughts of death or self-harm "not at all" to 4% among those reporting thoughts of death or self-harm "nearly every day." After adjustment for age, sex, treatment history, and overall depression severity, responses to item 9 of the PHQ-9 remained a strong predictor of suicide attempt. Cumulative risk of suicide death over one year increased from .03% among those reporting thoughts of death or self-harm ideation "not at all" to .3% among those reporting such thoughts "nearly every day." Response to item 9 remained a moderate predictor of subsequent suicide death after the same factor adjustments. CONCLUSIONS Response to item 9 of the PHQ-9 for depression identified outpatients at increased risk of suicide attempt or death. This excess risk emerged over several days and continued to grow for several months, indicating that suicidal ideation was an enduring vulnerability rather than a short-term crisis. PMID:24036589
Although relationships have been found between maternal psychological characteristics and cognitive and emotional outcomes in children, the behaviors which may mediate these relationships are seldom examined. This is especially true for adolescent mothers, whose children are thought to be at high risk for adverse outcomes. In this study, adolescent mothers in two special programs completed questionnaires measuring perception of the

Ubiquitous questionnaire, i.e., to provide users with E-questionnaire services anytime and anywhere such that one can use E-questionnaire servers without even thinking about them, is an ideal ubiquitous service in service-oriented computing.
Obsessions are traditionally defined as bothersome and repetitive thoughts that the patient is unable to resist. Preliminary evidence suggests that in a subgroup of patients with obsessive-compulsive disorder (OCD), obsessions are experienced as partially perceptual. The present study explored the frequency of perceptually laden obsessions and their relationship with illness insight and depression. Twenty-six patients with OCD were administered the newly developed Sensory Properties of Obsessions Questionnaire. Participants were asked to endorse on a 5-point Likert scale whether their obsessions were associated with perceptual features. Participants showed moderate symptom severity. A total of 73% affirmed that their obsessions contained perceptual features. The predominant perceptual channels were visual, tactile, and somatic (i.e., bodily sensations). The extent of perceptual aspects associated with obsessions was strongly correlated with lack of insight (Yale-Brown Obsessive-Compulsive Scale item 11) but not depression severity. The present study suggests that obsessive thoughts are frequently accompanied by perceptual sensations, which concurs with models assuming a continuum between hallucinations and intrusions. Apparently, the more "real" or authentic the obsessive thought is experienced, the less the afflicted person is able to dismiss its content as fully irrational or absurd. PMID:24933417

In computer aided mammography algorithms there are several processing steps, which must be performed. The basic segmentation procedure involves extracting the principal feature on a mammogram; the breast border. This is performed by segmenting the breast and the non-breast into distinct regions. In this paper, a method for extracting the breast border is proposed. The method has performance similar to established techniques but with higher degrees of automatization and robustness. It iteratively adapts a model of the background to ensure a robust object detection yielding a smooth outline of the breast. The main idea is to identify the "knee" in the cumulative intensity histogram of the image. The intensity value at the knee is thereafter used to automatically define a region, to be modelled by a two-dimensional polynomial surface of degree two. The modelled background is then subtracted from the original image. The procedure described is iteratively performed until the degree of non-uniformity of the grey-scale background is smaller then a certain value. Thereafter the difference image is post-processed by a flood-filling algorithm, a new threshold is estimated as above and applied to yield a binary image. Lastly morphological operations are performed to smoothen the breast border. In conclusion, the strength in the proposed method, compared to similar methods, is that it makes use of an iterative approach to reduce the effects of the background, it produces smooth edges and automatically finds thresholds. It is also evaluated on the entire MIAS database (322 images) with a performance of 94%.

A recent study by Apperly et al. (2006) found evidence that adults do not automatically infer false beliefs while watching videos that afford such inferences. This method was extended to examine true beliefs, which are sometimes thought to be ascribed by "default" (e.g., Leslie & Thaiss, 1992). Sequences of pictures were presented in which the…
Summary form only given, as follows. A learning algorithm for multilayered neural networks which is implemented by a Newton method using automatic differentiation was compared to the back-propagation method. It has been thought that the computational cost for obtaining second-order derivatives of an error function is very high, and that a system of linear equations (the Newton equations) cannot be
A measuring system is disclosed for surveying and very accurately positioning objects with respect to a reference line. A principal use of this surveying system is for accurately aligning the electromagnets which direct a particle beam emitted from a particle accelerator. Prior art surveying systems require highly skilled surveyors. Prior art systems include, for example, optical surveying systems which are susceptible to operator reading errors, and celestial navigation-type surveying systems, with their inherent complexities. The present invention provides an automatic readout micrometer which can very accurately measure distances. The invention has a simplicity of operation which practically eliminates the possibilities of operator optical reading error, owning to the elimination of traditional optical alignments for making measurements. The invention has an extendable arm which carries a laser surveying target. The extendable arm can be continuously positioned over its entire length of travel by either a coarse or fine adjustment without having the fine adjustment outrun the coarse adjustment until a reference laser beam is centered on the target as indicated by a digital readout. The length of the micrometer can then be accurately and automatically read by a computer and compared with a standardized set of alignment measurements. Due to its construction, the micrometer eliminates any errors due to temperature changes when the system is operated within a standard operating temperature range.

Recent psychometric results suggested that the phenomenon of thought-action fusion (TAF) is implicated in obsessive compulsive disorder (OCD). The construct of TAF has two components: (a) the belief that thinking about an unacceptable or disturbing event makes it more likely to happen and (b) the belief that having an unacceptable thought is the moral equivalent of carrying out the unacceptable
Information on history of suicidal thoughts and behaviors is critical in risk assessment, and multi-informant assessment has been recommended. Despite this, relatively little is known about parent–adolescent agreement regarding adolescent suicidality. To examine the extent and predictors of such agreement, 448 psychiatrically hospitalized adolescents and their parents were administered structured interviews assessing suicidal thoughts, plans, and attempts and completed measures
Attention to art and culture goes far back in the history of economic thought. In the seventeenth century those activities were viewed suspiciously as likely to be either wasteful extravagances of the aristocracy, or dangerous distractions for the working classes. Eighteenth century economic thinkers offered more positive and thoughtful speculations. Mandeville and Galiani observed that the prices of art works

When researchers use the term "mind wandering" for task-unrelated thoughts in signal detection tasks, we may fall into the trap of believing that spontaneous thoughts are task unrelated in a deeper sense. Similar negative connotations are attached to common terms like "cognitive failures", "resting state", "rumination", "distraction", "attentional…

We argue that thought insertion primarily involves a disruption of the sense of ownership for thoughts and that the lack of a sense of agency is but a consequence of this disruption. We defend the hypothesis that this disruption of the sense of ownership stems from a failure in the online integration of the contextual information related to a thought, in particular contextual information concerning the different causal factors that may be implicated in their production. Loss of unity of consciousness, manifested by incoherent subjective experiences is a general phenomenal characteristic of schizophrenia. This loss of coherence has been hypothesized to reflect a generalized deficit of contextual information integration not conveyed by, but related to, a target event. This deficit is manifested across many cognitive domains. We argue that it is also manifested in the process of thinking itself, resulting in causally decontextualized thoughts that are experienced as inserted thoughts. PMID:23262256
In previous experiments on unconscious thought, information was presented to participants in one continuous session; however, in daily life, information is delivered in a temporally partitioned way. We examined whether unconscious thought could equally integrate temporally scattered information when making overall evaluations. When presenting participants with information in two temporally partitioned sessions, participants' overall evaluation was based on neither the information in the first session (Experiment 1) nor that in the second session (Experiment 2); instead, information in both sessions were equally integrated to reach a final judgment. Conscious thought, however, overemphasized information in the second session. Experiments 3 and 4 further ruled out possible influencing factors including differences in the distributions of positive/negative attributes in the first and second sessions and on-line judgment. These findings suggested that unconscious thought can integrate information from a wider range of periods during an evaluation, while conscious thought cannot. PMID:24583456

An automatic vehicle detection system is disclosed, in which each vehicle whose location is to be detected carries active means which interact with passive elements at each location to be identified. The passive elements comprise a plurality of passive loops arranged in a sequence along the travel direction. Each of the loops is tuned to a chosen frequency so that the sequence of the frequencies defines the location code. As the vehicle traverses the sequence of the loops as it passes over each loop, signals only at the frequency of the loop being passed over are coupled from a vehicle transmitter to a vehicle receiver. The frequencies of the received signals in the receiver produce outputs which together represent a code of the traversed location. The code location is defined by a painted pattern which reflects light to a vehicle carried detector whose output is used to derive the code defined by the pattern.
Automatic Routing Module (ARM) is a tool to partially automate Air Launched Cruise Missile (ALCM) routing. For any accessible launch point or target pair, ARM creates flyable routes that, within the fidelity of the models, are optimal in terms of threat avoidance, clobber avoidance, and adherence to vehicle and planning constraints. Although highly algorithmic, ARM is an expert system. Because of the heuristics applied, ARM generated routes closely resemble manually generated routes in routine cases. In more complex cases, ARM's ability to accumulate and assess threat danger in three dimensions and trade that danger off with the probability of ground clobber results in the safest path around or through difficult areas. The tools available prior to ARM did not provide the planner with enough information or present it in such a way that ensured he would select the safest path.
This alkaloid automated removal machine was developed at Instrumentation Laboratory, Universiti Sultan Zainal Abidin Malaysia that purposely for removing the alkaloid toxicity from Dioscorea hispida (DH) tuber. It is a poisonous plant where scientific study has shown that its tubers contain toxic alkaloid constituents, dioscorine. The tubers can only be consumed after it poisonous is removed. In this experiment, the tubers are needed to blend as powder form before inserting into machine basket. The user is need to push the START button on machine controller for switching the water pump ON by then creating turbulence wave of water in machine tank. The water will stop automatically by triggering the outlet solenoid valve. The powders of tubers are washed for 10 minutes while 1 liter of contaminated water due toxin mixture is flowing out. At this time, the controller will automatically triggered inlet solenoid valve and the new water will flow in machine tank until achieve the desire level that which determined by ultra sonic sensor. This process will repeated for 7 h and the positive result is achieved and shows it significant according to the several parameters of biological character ofpH, temperature, dissolve oxygen, turbidity, conductivity and fish survival rate or time. From that parameter, it also shows the positive result which is near or same with control water and assuming was made that the toxin is fully removed when the pH of DH powder is near with control water. For control water, the pH is about 5.3 while water from this experiment process is 6.0 and before run the machine the pH of contaminated water is about 3.8 which are too acid. This automated machine can save time for removing toxicity from DH compared with a traditional method while less observation of the user. PMID:24783795

Many groups around the world are developing automated or robotic optical observatories. The coordinated operation of automated optical telescopes at diverse sites could provide observing prospects which are not otherwise available, e.g., continuous optical photometry without diurnal interruption. Computer control and scheduling also offers the prospect of effective response to transient events such as ? -ray bursts. These telescopes could also serve science education by providing high-quality CCD data for educators and students. The Automatic Telescope Network (ATN) project has been undertaken to promote networking of automated telescopes. A web site is maintained at http://gamma.bu.edu/atn/. The development of such networks will be facilitated by the existence of standards. A set of standard commands for instrument and telescope control systems will allow for the creation of software for an ``observatory control system'' which can be used at any facility which complies with the TCS and ICS standards. Also, there is a strong need for standards for the specification of observations to be done, and reports on the results and status of observations. A proposed standard for this is the Remote Telescope Markup Language (RTML), which is expected to be described in another poster in this session. It may thus be feasible for amateur-astronomers to soon buy all necessary equipment and software to field an automatic telescope. The owner/operator could make otherwise unused telescope time available to the network in exchange for the utilization of other telescopes in the network --- including occasional utilization of meter-class telescopes with research-grade CCD detectors at good sites.

Automatic Sequence Generator (Autogen) Version 3.0 software automatically generates command sequences for the Mars Reconnaissance Orbiter (MRO) and several other JPL spacecraft operated by the multi-mission support team. Autogen uses standard JPL sequencing tools like APGEN, ASP, SEQGEN, and the DOM database to automate the generation of uplink command products, Spacecraft Command Message Format (SCMF) files, and the corresponding ground command products, DSN Keywords Files (DKF). Autogen supports all the major multi-mission mission phases including the cruise, aerobraking, mapping/science, and relay mission phases. Autogen is a Perl script, which functions within the mission operations UNIX environment. It consists of two parts: a set of model files and the autogen Perl script. Autogen encodes the behaviors of the system into a model and encodes algorithms for context sensitive customizations of the modeled behaviors. The model includes knowledge of different mission phases and how the resultant command products must differ for these phases. The executable software portion of Autogen, automates the setup and use of APGEN for constructing a spacecraft activity sequence file (SASF). The setup includes file retrieval through the DOM (Distributed Object Manager), an object database used to store project files. This step retrieves all the needed input files for generating the command products. Depending on the mission phase, Autogen also uses the ASP (Automated Sequence Processor) and SEQGEN to generate the command product sent to the spacecraft. Autogen also provides the means for customizing sequences through the use of configuration files. By automating the majority of the sequencing generation process, Autogen eliminates many sequence generation errors commonly introduced by manually constructing spacecraft command sequences. Through the layering of commands into the sequence by a series of scheduling algorithms, users are able to rapidly and reliably construct the desired uplink command products. With the aid of Autogen, sequences may be produced in a matter of hours instead of weeks, with a significant reduction in the number of people on the sequence team. As a result, the uplink product generation process is significantly streamlined and mission risk is significantly reduced. Autogen is used for operations of MRO, Mars Global Surveyor (MGS), Mars Exploration Rover (MER), Mars Odyssey, and will be used for operations of Phoenix. Autogen Version 3.0 is the operational version of Autogen including the MRO adaptation for the cruise mission phase, and was also used for development of the aerobraking and mapping mission phases for MRO.

Robotic welding has been of interest to industrial firms because it offers higher productivity at lower cost than manual welding. There are some systems with automated arc guidance available, but they have disadvantages, such as limitations on types of materials or types of seams that can be welded; susceptibility to stray electrical signals; restricted field of view; or tendency to contaminate the weld seam. Wanting to overcome these disadvantages, Marshall Space Flight Center, aided by Hayes International Corporation, developed system that uses closed-circuit TV signals for automatic guidance of the welding torch. NASA granted license to Combined Technologies, Inc. for commercial application of the technology. They developed a refined and improved arc guidance system. CTI in turn, licensed the Merrick Corporation, also of Nashville, for marketing and manufacturing of the new system, called the CT2 Optical Trucker. CT2 is a non-contracting system that offers adaptability to broader range of welding jobs and provides greater reliability in high speed operation. It is extremely accurate and can travel at high speed of up to 150 inches per minute.
A system that automatically segments and labels complete glioblastoma-multiform tumor volumes in magnetic resonance images of the human brain is presented. The magnetic resonance images consist of three feature images (T1- weighted, proton density, T2-weighted) and are processed by a system which integrates knowledge-based techniques with multispectral analysis and is independent of a particular magnetic resonance scanning protocol. Initial segmentation is performed by an unsupervised clustering algorithm. The segmented image, along with cluster centers for each class are provided to a rule-based expert system which extracts the intra-cranial region. Multispectral histogram analysis separates suspected tumor from the rest of the intra-cranial region, with region analysis used in performing the final tumor labeling. This system has been trained on eleven volume data sets and tested on twenty-two unseen volume data sets acquired from a single magnetic resonance imaging system. The knowledge-based tumor segmentation was compared with radiologist-verified `ground truth' tumor volumes and results generated by a supervised fuzzy clustering algorithm. The results of this system generally correspond well to ground truth, both on a per slice basis and more importantly in tracking total tumor volume during treatment over time.

Objective: Providing care to a relative with dementia is associated with negative health consequences. Experiential avoidance has been found to be related to caregivers' distress. However, no specific measure of experiential avoidance in the caregiving context is available. The aim of this study is to develop and present the psychometric properties of the Experiential Avoidance in Caregiving Questionnaire (EACQ).Method: Face-to-face interviews were conducted with 263 dementia family caregivers (mean age = 61.37; SD = 14.84; 78.3% female). In addition to the EACQ, the Action and Acceptance Questionnaire (AAQ) was used. Depression, anxiety, alexithymia, cognitive fusion, dysfunctional thoughts about caregiving, and mean arterial pressure were also measured.Results: Using principal component analysis, three factors were retained that explained 44.75% of the variance. These factors were labeled: (1) Active Avoidant Behaviors; (2) Intolerance of Negative Thoughts and Emotions Towards the Relative; and (3) Apprehension Concerning Negative Internal Experiences Related to Caregiving. Acceptable reliability indexes (Cronbach's alpha) were found for each factor (.63 for factor 1; .71 for factor 2; and .60 for factor 3) and the total scale (? = .70). Significant positive associations were found between the global scale and anxiety, dysfunctional thoughts, alexithymia and the AAQ.Conclusion: The EACQ shows acceptable psychometric properties and may be a useful tool for clinical assessment and therapeutic work with caregivers.

Background Back pain in children is common and early onset of back pain has been shown to increase the risk of back pain significantly in adulthood. Consequently, preventive efforts must be targeted the young population but research relating to spinal problems in this age group is scarce. Focus has primarily been on the working age population, and therefore specific questionnaires to measure spinal pain and its consequences, specifically aimed at children and adolescents are absent. The purpose of this study was to develop a questionnaire for schoolchildren filling this gap. Methods The Young Spine Questionnaire (YSQ) was developed in three phases – a conceptualisation, development and testing phase. The conceptualisation phase followed the Wilson and Cleary model and included questions regarding spinal prevalence estimates, pain frequency and intensity, activity restrictions, care seeking behaviour and influence of parental back trouble. Items from existing questionnaires and the “Revised Faces Pain Scale” (rFPS) were included during the development phase. The testing phase consisted of a mixed quantitative and qualitative iterative method carried out in two pilot tests using 4th grade children and focusing on assessment of spinal area location and item validity. Results The testing phase resulted in omission of the pain drawings and the questions and answer categories were simplified in several questions. Agreement between the questionnaire prevalence estimates and the interviews ranged between 83.7% (cervical pain today) and 97.9% (thoracic pain today). To improve the understanding of the spinal boundaries we added bony landmarks to the spinal drawings after pilot test I. This resulted in an improved sense of spinal boundary location in pilot test II. Correlations between the rFPS and the interview pain score ranged between 0.67 (cervical spine) and 0.79 (lumbar spine). Conclusions The Young Spine Questionnaire contains questions that assess spinal pain and its consequences. The items have been tested for content understanding and agreement between questionnaire scores and interview findings among target respondents. These preliminary results suggest that the YSQ is feasible, has content validity and is a well understood questionnaire to be used in studies of children aged 9 to 11 years.

The objective of automatic programming is to improve the overall environment for describing the program. This improved environment is realized by a reduction in the amount of detail that the programmer needs to know and is exposed to. Furthermore, this improved environment is achieved by a specification language that is more natural to the user's problem domain and to the user's way of thinking and looking at the problem. The goal of this research is to apply the concepts of automatic programming (AP) to modeling discrete event simulation system. Specific emphasis is on the design and development of simulation tools to assist the modeler define or construct a model of the system and to then automatically write the corresponding simulation code in the target simulation language, GPSS/PC. A related goal is to evaluate the feasibility of various languages for constructing automatic programming simulation tools.

Instructions are presented on the use of ADMAP, (automatic data manipulation program) an aerospace data manipulation computer program. The program was developed to aid in processing, reducing, plotting, and publishing electric propulsion trajectory data generated by the low thrust optimization program, HILTOP. The program has the option of generating SC4020 electric plots, and therefore requires the SC4020 routines to be available at excution time (even if not used). Several general routines are present, including a cubic spline interpolation routine, electric plotter dash line drawing routine, and single parameter and double parameter sorting routines. Many routines are tailored for the manipulation and plotting of electric propulsion data, including an automatic scale selection routine, an automatic curve labelling routine, and an automatic graph titling routine. Data are accepted from either punched cards or magnetic tape.

Cognitive scientists routinely distinguish between controlled and automatic mental processes. Through learning, practice, and exposure, controlled processes can become automatic; however, whether automatic processes can become deautomatized - recuperated under the purview of control - remains unclear. Here we show that a suggestion derails a deeply ingrained process involving involuntary audiovisual integration. We compared the performance of highly versus less hypnotically suggestible individuals (HSIs versus LSIs) in a classic McGurk paradigm - a perceptual illusion task demonstrating the influence of visual facial movements on auditory speech percepts. Following a posthypnotic suggestion to prioritize auditory input, HSIs but not LSIs manifested fewer illusory auditory perceptions and correctly identified more auditory percepts. Our findings demonstrate that a suggestion deautomatized a ballistic audiovisual process in HSIs. In addition to guiding our knowledge regarding theories and mechanisms of automaticity, the present findings pave the road to a more scientific understanding of top-down effects and multisensory integration.

Experimental psychopathologists have increasingly relied upon the concepts and methods of cognitive psychology in their attempts to elucidate information-processing biases associated with anxiety disorders. Many of these biases presumably constitute instances of automatic, not strategic, processing. But research has shown that attributes of automaticity (i.e. capacity-free, unconsious, involuntary) do not all apply to selective processing of threat associated with anxiety.
Automatic test equipment (ATE) is a term that, in its broadest meaning, indicates a generic system capable of performing measurements in an automatic or semiautomated (human-assisted) way. Years ago, this term was used specifically to refer to an automated measurement system employed to test the functionality of some electronic device-under-test (DUT). Typical applications were in the manufacturing area, where ATE

There is rising interest in identifying precursors to bipolar disorder symptoms, including thought disorder. Thought disorder is identified in adults through self-report and in school-aged children through parent report and child story-telling. This study is an exploration to determine if preschoolers with mood dysregulation have evidence of disordered thoughts using a story-stem completion method. Participants included two groups of 3.5-6 year-old children: 20 with mood dysregulation including manic symptoms and 11 typically developing comparison children. Children were administered story completion narratives including one story where the child character accidentally cuts him/herself while pretending to cook. The children were asked to complete the stories and their responses were analyzed for atypical themes consistent with disordered thoughts such as violence or bizarreness outside of the story or props coming to life. Thirty-five percentage of symptomatic preschoolers versus 0% of typically developing preschoolers ascribed independent actions to inanimate props (p = 0.03). Eighty percentage of symptomatic preschoolers versus 9% of typically developing preschoolers utilized props in a violent or bizarre manner outside the central story (p < 0.001). Preschool children with symptoms of dysregulated mood express themes related to the unusual use of story props which may indicate disordered thoughts. This preschool expression of dysregulated mood appears similar to and possibly continuous with school-age and adult versions of bipolar disorder. PMID:20387113

Objective To determine the prevalence of suicidal thoughts and attempts and to identify demographic variables and mental health correlates such as anxiety/depression and domestic violence among pregnant women in an urban community in Pakistan. Design Cross sectional data from a prospective cohort study are presented. Setting Women enrolled in an antenatal care clinic and followed to delivery in an urban area of Pakistan Population Cohort of pregnant women in Pakistan. Methods 1,369 pregnant women were enrolled and interviewed regarding various maternal characteristics and pregnancy outcomes, and were asked specific questions about suicidal thoughts and attempts and administered the Aga Khan University Anxiety Depression Scale at 20–26 weeks of gestation. Main outcome measures Suicidal thoughts and attempts, verbal, sexual or physical abuse. Results Overall, 148 of the 1369 (11%) women studied had considered suicide. Of these, 148 women, 67 (45%) had attempted suicide. Eighteen percent of the women were classified as having depression/anxiety, almost half (48%) reported experiencing verbal abuse and 20% reported physical/sexual abuse. Women who had anxiety/depression or had experienced verbal or physical/sexual abuse were significantly more likely to have had suicidal thoughts and attempts. Conclusions Women at greatest risk for having suicidal thoughts or a suicide attempt were those who were depressed/anxious and had experienced some form of domestic abuse. With the high prevalence of these conditions, attention should be given to the establishment of effective mental health treatment programs for pregnant women.

Objectives The Survey of Living Condition in the Arctic (SLiCA) is an international research project on health and living conditions among Arctic indigenous peoples. The main objective of this article is to examine the prevalence of self-reported suicide thoughts among the study population in Alaska, Greenland, Sweden and Norway. Study design Population-based survey. Methods Indigenous participants aged 16 years (15 years in Greenland) and older living in traditional settlement regions in Alaska, Sweden and Norway and across the entire Greenland were invited to participate. Data were collected in three periods: in Alaska from January 2002 to February 2003, in Greenland from December 2003 to August 2006, in Sweden from spring 2004 to 2006 and in Norway in 2003 and from June 2006 to June 2008. The principal method in SLiCA was standardised face-to-face interviews using a questionnaire. A questionnaire had among other things, questions about health, education, traditional activities, ethnicity and suicidal thoughts. Results Information about suicidal thoughts, gender and age were available in 2,099 participants between the ages of 16 and 84 from Alaska, Greenland, Sweden and Norway. Greenland had the highest rates of suicidal thoughts when adjusting for age and gender (p=0.003). When stratifying on age and gender, significant differences across countries were only found for females in the two youngest age groups. Differences in suicidal thoughts across countries could partly be explained by educational level. Conclusion Swedish respondents had less suicidal thoughts than those in any other countries. In the future, analyses of suicidal thoughts should take socioeconomic status into account as well as self- reported health, depression and anxiety.
Purpose: This study investigated the presence and influence of intrusive thoughts among adults previously diagnosed with complex regional pain syndrome. Method: The present study used an Internet-based survey completed by a sample (N = 326) from two national organizations. Results: After controlling for age, gender, and pain level, intrusive thoughts were significantly related to disability and health-related quality of life. Conclusions/Implications: Intrusive thoughts about the inciting event that caused CRPS uniquely influenced pain and quality of life, suggesting a potential mechanism to target for intervention. Understanding factors that relate to maintenance of CRPS and its resulting disability will help in the development of treatments to improve quality of life.

To simplify telemetry software development, a design that eliminates the use of software instructions to address telemetry channels is being implemented in our telemetry systems. By using the direct memory access function of the RCA 1802 microprocessor, once initialized, addressing of telemetry channels is automatic, requiring no software. In this report the automatic addressing of telemetry channels (AATC) scheme is compared with an earlier technique that uses software. In comparison, the automatic addressing scheme effectively increases the software capability of the microprocessor, simplifies telemetry dataset encoding, eases dataset changes, and may decrease the electronic hardware count. The software addressing technique uses at least three instructions to address each channel. The automatic addressing technique requires no software instructions. Instead, addressing is performed using a direct memory access cycle stealing technique. Application of an early version of this addressing scheme to telemetry Type 1, Dataset 3, opened up the capability to execute 400 more microprocessor instructions than could be executed using the software addressing scheme. The present version of the automatic addressing scheme uses a section of PROM reserved for telemetry channel addresses. Encoding for a dataset is accomplished by programming the PROM with channel addresses in the order they are to be monitored. The telemetry Type 2 software was written using the software addressing scheme, then rewritten using the automatic addressing scheme. While 1000 bytes of memory were required by the software addressing scheme, the automatic addressing scheme required only 396 bytes. A number of prototypes using AATC have been built and tested in a full telemetry lab unit. All have worked successfully.

Empathy refers to the thoughts and feelings of one individual in response to the observed (emotional) experiences of another individual. Empathy, however, can occur toward persons experiencing a variety of emotions, raising the question of whether or not empathy can be emotion specific. This paper discusses theoretical and empirical support for the emotion specificity of empathy. We present a new measure, the Emotion Specific Empathy questionnaire, which assesses affective and cognitive empathy for the six basic emotions. This paper presents the measure's psychometric qualities and demonstrates, through a series of models, the discriminant validity between emotion specific empathies suggesting empathy is emotion specific. Results and implications are discussed.

In 1928, the Library of Virginia inherited a mass of materials from the Virginia War History Commission, which had spent the previous eight years gathering information on Virginia's participation in World War I. Included in this material were over 14,900 four-page questionnaires from a survey of WWI veterans in Virginia. The Library of Virginia has digitized these survey forms and created a free, fully-searchable database. Users have three search options: by word or phrase, combination, and expert/boolean. Search returns offer basic information on each individual, and users must follow the link at the bottom of the page to download the digitized images (in .tif format) of the questionnaire forms. In some cases, respondents submitted photos or additional pages with their forms and these are included in the database.

This paper discusses Frank H. Knight's thought under three major themes, namely subjectivism, interpretation and social economics. Knight's economics starts with a conscious mind construct which is able to infer under partial knowledge. Conscious human action is purposive, forward looking and extends towards other individuals. Rejecting neoclassical positivism, Knight points to the need for economics to reconceptualize itself as an

Neural structures of interaction between thinking and language are unknown. This paper suggests a possible architecture motivated by neural and mathematical considerations. A mathematical requirement of computability imposes significant constraints on possible architectures consistent with brain neural structure and with a wealth of psychological knowledge. How language interacts with cognition. Do we think with words, or is thinking independent from language with words being just labels for decisions? Why is language learned by the age of 5 or 7, but acquisition of knowledge represented by learning to use this language knowledge takes a lifetime? This paper discusses hierarchical aspects of language and thought and argues that high level abstract thinking is impossible without language. We discuss a mathematical technique that can model the joint language-thought architecture, while overcoming previously encountered difficulties of computability. This architecture explains a contradiction between human ability for rational thoughtful decisions and irrationality of human thinking revealed by Tversky and Kahneman; a crucial role in this contradiction might be played by language. The proposed model resolves long-standing issues: how the brain learns correct words-object associations; why animals do not talk and think like people. We propose the role played by language emotionality in its interaction with thought. We relate the mathematical model to Humboldt’s “firmness” of languages; and discuss possible influence of language grammar on its emotionality. Psychological and brain imaging experiments related to the proposed model are discussed. Future theoretical and experimental research is outlined.

It is pointed out that the engineer or scientist is interested in obtaining results with a minimum of personal effort. In this connection, much attention has been given to the development of systems for the automatic solution of partial differential equations (PDEs), taking into account also the solution of ordinary differential equations (ODEs). The state of the art of software for PDE implies that there is a need for the development of new systems. Attention is given to the development of a new iterative system for the automatic solution of nonlinear PDEs. Equations, boundary conditions, order of approximation, and special instructions are specified by the user. The system, which is called ARIEL, automatically generates, compiles, loads, and executes a new program according to the specifications. The software for the PDEs is discussed and a description for ARIEL is provided.

Rollers guide grinding tool along prospective welding path. Skatelike fixture holds rotary grinder or file for machining large-diameter rings or ring segments in preparation for welding. Operator grasps handles to push rolling fixture along part. Rollers maintain precise dimensional relationship so grinding wheel cuts precise depth. Fixture-mounted grinder machines surface to quality sufficient for automatic welding; manual welding with attendant variations and distortion not necessary. Developed to enable automatic welding of parts, manual welding of which resulted in weld bead permeated with microscopic fissures.
The automatic interpretation of apparent resistivity curves from horizontally layered earth models is carried out by the curve-fitting method in three steps: (1) the observed VES data are interpolated at equidistant points of electrode separations on the logarithmic scale by using the cubic spline function, (2) the layer parameters which are resistivities and depths are predicted from the sampled apparent resistivity values by SALS system program and (3) the theoretical VES curves from the models are calculated by Ghosh's linear filter method using the Zhody's computer program. Two soundings taken over Takenoyu geothermal area were chosen to test the procedures of the automatic interpretation.

Although neural activity often reflects the processing of external inputs, intrinsic fluctuations in activity have been observed throughout the brain. These may relate to patterns of self-generated thought that can occur while not performing goal-driven tasks. To understand the relationship between self-generated mental activity and intrinsic neural fluctuations, we developed the New York Cognition Questionnaire (NYC-Q) to assess the content and form of an individual's experiences during the acquisition of resting-state fMRI data. The data were collected as a part of the Nathan Kline Rockland Enhanced sample. We decomposed NYC-Q scores using exploratory factor analysis and found that self-reported thoughts clustered into distinct dimensions of content (future related, past related, positive, negative, and social) and form (words, images, and specificity). We used these components to perform an individual difference analysis exploring how differences in the types of self-generated thoughts relate to whole brain measures of intrinsic brain activity (fractional amplitude of low frequency fluctuations, regional homogeneity, and degree centrality). We found patterns of self-generated thoughts related to changes that were distributed across a wide range of cortical areas. For example, individuals who reported greater imagery exhibited greater low frequency fluctuations in a region of perigenual cingulate cortex, a region that is known to participate in the so-called default-mode network. We also found certain forms of thought were associated with other areas, such as primary visual cortex, the insula, and the cerebellum. For example, individuals who reported greater future thought exhibited less homogeneous neural fluctuations in a region of lateral occipital cortex, a result that is consistent with the claim that particular types of self-generated thought depend on processes that are decoupled from sensory processes. These data provide evidence that self-generated thought is a heterogeneous category of experience and that studying its content can be helpful in understanding brain dynamics. PMID:24824880

Background Suicide, attempted suicide and suicidal thoughts are major public health problems worldwide. Effective face-to-face treatments are Cognitive Behavioural Therapy (CBT), Dialectical Behavioural Therapy (DBT) and Problem Solving Treatment (PST). However, about two-thirds of persons who die by suicide have not been in contact with mental health care services in the preceding year, and many have never been treated. Furthermore, many patients do not disclose their suicidal thoughts to their care provider. This may be out of shame, due to fear of stigma or due to lack of trust in (mental) health care. Since many suicidal individuals seek information online, the internet provides an opportunity to reach suicidal individuals who would not be contacted otherwise. By providing a self-help intervention online, persons can anonymously learn to gain control over their suicidal thoughts. There is convincing evidence that self-help is effective for a number of mental disorders. In this study the effectiveness for suicidal thoughts is examined. Methods/Design In this study, a recently developed self-help intervention will be evaluated in a Randomized Controlled Trial. The intervention is based on Cognitive Behavioural Therapy and is aimed at subjects who experience mild to moderate suicidal thoughts. This is defined as a score between 1 and 26 on the Beck Scale for Suicidal Ideation (BSS). Higher and lower scores are excluded. In addition, severely depressed subjects are excluded. In total, 260 subjects will be randomly allocated to the intervention-condition (N = 130) or to the information-control condition (N = 130). Self-report questionnaires will be filled out at baseline, 6 weeks after baseline and 18 weeks after baseline. Primary outcome measure is the reduction in frequency and intensity of suicidal thoughts. Secondary outcome measures are the reduction of hopelessness, anxiety and depression, sleeplessness, worry and quality of life measures. Discussion This study is the first to evaluate the effectiveness of a web-based self-help intervention for suicidal thoughts. Several limitations and strengths of the design are discussed. Trial Registration Netherlands Trial Register, NTR1689
Background: This study was designed to assess the validity and reliability of the designed sexual, behavioral abstinence, and avoidance of high-risk situation questionnaire (SBAHAQ), with an aim to construct an appropriate development tool in the Iranian population. Materials and Methods: A descriptive–analytic study was conducted among female undergraduate students of Tehran University, who were selected through cluster random sampling. After reviewing the questionnaires and investigating face and content validity, internal consistency of the questionnaire was assessed by Cronbach's alpha. Explanatory and confirmatory factor analysis was conducted using SPSS and AMOS 16 Software, respectively. Results: The sample consisted of 348 female university students with a mean age of 20.69 ± 1.63 years. The content validity ratio (CVR) coefficient was 0.85 and the reliability of each section of the questionnaire was as follows: Perceived benefit (PB; 0.87), behavioral intention (BI; 0.77), and self-efficacy (SE; 0.85) (Cronbach's alpha totally was 0.83). Explanatory factor analysis showed three factors, including SE, PB, and BI, with the total variance of 61% and Kaiser–Meyer–Olkin (KMO) index of 88%. These factors were also confirmed by confirmatory factor analysis [adjusted goodness of fitness index (AGFI) = 0.939, root mean square error of approximation (RMSEA) = 0.039]. Conclusion: This study showed the designed questionnaire provided adequate construct validity and reliability, and could be adequately used to measure sexual abstinence and avoidance of high-risk situations among female students.

Automatically labeling document clusters with words which indicate their topics is difficult to do well. The most commonly used method, labeling with the most frequent words in the clusters, ends up using many words that are virtually void of descriptive power even after traditional stop words are removed. Another method, labeling with the most predictive words, often includes rather obscure

Different psychotherapeutic approaches claim positive changes in patients as a result of therapy. Explanations related to the change process led to different change models. Some of the change models are experimentally oriented whereas some are theoretical. Apart from the core models of behavioral, psychodynamic, humanistic, cognitive and spiritually oriented models there are specific models, within psychotherapy that explains the change process. Integrative theory of a person as depicted in Indian thought provides a common ground for the integration of various therapies. Integrative model of change based on Indian thought, with specific reference to psychological concepts in Upanishads, Ayurveda, Bhagavad Gita and Yoga are presented. Appropriate psychological tools may be developed in order to help the clinicians to choose the techniques that match the problem and the origin of the dimension. Explorations have to be conducted to develop more techniques that are culturally appropriate and clinically useful. Research has to be initiated to validate the identified concepts.
Information on history of suicidal thoughts and behaviors is critical in risk assessment, and multi-informant assessment has been recommended. Despite this, relatively little is known about parent-adolescent agreement regarding adolescent suicidality. To examine the extent and predictors of such agreement, 448 psychiatrically hospitalized adolescents and their parents were administered structured interviews assessing suicidal thoughts, plans, and attempts and completed measures of youth internalizing and externalizing behaviors, perceived family social support, and parental distress and psychopathology. Adolescents reported significantly more suicidal ideation, plans, and attempts than parents. Parental history of depression and adolescent perceived family support were associated with significantly greater agreement about suicidality. History of multiple suicide attempts was associated with greater disagreement about suicidality.

Is human thought fully embedded in language, or do some forms of thought operate independently? To directly address this issue, we focus on inference-making, a central feature of human cognition. In a 3T fMRI study we compare logical inferences relying on sentential connectives (e.g., not, or, if … then) to linguistic inferences based on syntactic transformation of sentences involving ditransitive verbs (e.g., give, say, take). When contrasted with matched grammaticality judgments, logic inference alone recruited “core” regions of deduction [Brodmann area (BA) 10p and 8m], whereas linguistic inference alone recruited perisylvian regions of linguistic competence, among others (BA 21, 22, 37, 39, 44, and 45 and caudate). In addition, the two inferences commonly recruited a set of general “support” areas in frontoparietal cortex (BA 6, 7, 8, 40, and 47). The results indicate that logical inference is not embedded in natural language and confirm the relative modularity of linguistic processes.

Impairments in executive functioning have been identified as an underlying cause of Obsessive-Compulsive Disorder (OCD). Obsessive patients attempt to suppress certain unwanted thoughts through a mechanism that Wegner referred to as 'chronic thought suppression', whereas compulsive patients are unable to inhibit their rituals. We tested 51 OCD patients using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the White Bear Suppression Inventory (WBSI) and the Dysexecutive Questionnaire (DEX). Executive functions were tested using a cognitive test battery. We found that the total WBSI score was correlated with the Y-BOCS obsessive score but not with the Y-BOCS compulsive score. A stronger correlation was observed between the Y-BOCS obsessive score and the 'unwanted intrusive thoughts' factor based on Blumberg's 3-factor model of the WBSI. The total WBSI score was not correlated with the cognitive test results. The DEX score was significantly correlated with the Y-BOCS compulsive score; however, no correlation was found between the DEX score and the Y-BOCS obsessive score. A stronger correlation was observed between the Y-BOCS compulsive score and the 'inhibition' component of the DEX score, as defined by Burgess's 5-factor model. The DEX scores were correlated with cognitive test results measuring attention, cognitive flexibility and inhibitory processes. We conclude that obsessions indicate a failure of cognitive inhibition but do not involve significant impairment of executive functions, whereas compulsions indicate ineffective behavior inhibition and impaired executive functions.

Despite evidence pointing to a ubiquitous tendency of human minds to wander, little is known about the neural operations that support this core component of human cognition. Using both thought sampling and brain imaging, the current investigation demonstrated that mind-wandering is associated with activity in a default network of cortical regions that are active when the brain is "at rest." In addition, individuals' reports of the tendency of their minds to wander were correlated with activity in this network. PMID:17234951

Objective To estimate the extent to which exposure to music through earphones or headphones with MP3 players or at discotheques and pop/rock concerts exceeded current occupational safety standards for noise exposure, to examine the extent to which temporary and permanent hearing-related symptoms were reported, and to examine whether the experience of permanent symptoms was associated with adverse perceived general and mental health, symptoms of depression, and thoughts about suicide. Methods A total of 943 students in Dutch inner-city senior-secondary vocational schools completed questionnaires about their sociodemographics, music listening behaviors and health. Multiple logistic regression analyses were used to examine associations. Results About 60% exceeded safety standards for occupational noise exposure; about one third as a result of listening to MP3 players. About 10% of the participants experienced permanent hearing-related symptoms. Temporary hearing symptoms that occurred after using an MP3 player or going to a discotheque or pop/rock concert were associated with exposure to high-volume music. However, compared to participants not experiencing permanent hearing-related symptoms, those experiencing permanent symptoms were less often exposed to high volume music. Furthermore, they reported at least two times more often symptoms of depression, thoughts about suicide and adverse self-assessed general and mental health. Conclusions Risky music-listening behaviors continue up to at least the age of 25 years. Permanent hearing-related symptoms are associated with people’s health and wellbeing. Participants experiencing such symptoms appeared to have changed their behavior to be less risky. In order to induce behavior change before permanent and irreversible hearing-related symptoms occur, preventive measurements concerning hearing health are needed.

Thought Experiments are powerful tools in both scientific thinking and in the teaching of science. In this study, the historical Thought Experiment (TE) `Newton's Cannon' was used as a tool to teach concepts relating to the motion of satellites to students at upper secondary level. The research instruments were: (a) a teaching-interview designed and implemented according to the Teaching Experiment methodology and (b) an open-ended questionnaire administered to students 2 weeks after the teaching-interview. The sample consisted of forty students divided into eleven groups. The teaching and learning processes which occurred during the teaching-interview were recorded and analyzed. The findings of the present study show that the use of the TE helped students to mentally construct a physical system which has nothing to do with their everyday experience (i.e. they had to imagine themselves as observers in a context in which the whole Earth was visible) and to draw conclusions about phenomena within this system. Specifically, students managed (1) to conclude that if an object is appropriately launched, it may be placed in an orbit around the Earth and to support this conclusion by giving necessary arguments, and (2) to realize that the same laws of physics describe, on the one hand, the motion of the Moon around the Earth (and the motion of other celestial bodies as well) and, on the other hand, the motion of `terrestrial' objects (i.e. objects on the Earth, such as a tennis ball). The main difficulties students met were caused by their idea that there is no gravity in the vacuum (i.e. the area outside of the Earth's atmosphere) and also by their everyday experience, according to which it is impossible for a projectile to move continuously parallel to the ground.
Limited published data are available on dermatophytosis in zoo macropods, despite anecdotal reports of disease occurrence and recurrent mob outbreaks. The aim of this questionnaire study was to analyze data from Australian and international zoos to evaluate estimated disease prevalence in zoos housing macropods, affected macropod species, causative organisms, predisposing factors, clinical presentations, diagnostics, treatments, and disease risk management. Two questionnaires (initial detailed and subsequent brief) were distributed via email to zoo veterinarians, with an estimated response rate of 23%. The overall estimated disease prevalence from responding zoos was 28%, with 73% of responding Australian zoos and 14% of responding non-Australian zoos reporting disease. The first cases of confirmed and suspected dermatophytosis in several macropod species and in association with Trichophyton verrucosum and Trichophyton mentagrophytes var. nodulare are reported, with young red kangaroos (Macropus rufus) appearing predisposed. Diagnosis was most commonly based on fungal culture or presumptively on typical clinical signs of minimally/nonpruritic alopecia, crusting, and scaling distributed most frequently on the tail, pinnae, and hind limbs. Both disease resolution without treatment and resolution after an average of 1 to 2 mo of treatment were reported. PMID:24063082

Many diseases involve the cerebellum and produce ataxia, which is characterized by incoordination of balance, gait, extremity and eye movements, and dysarthria. Cerebellar lesions do not always manifest with ataxic motor syndromes, however. The cerebellar cognitive affective syndrome (CCAS) includes impairments in executive, visual-spatial, and linguistic abilities, with affective disturbance ranging from emotional blunting and depression, to disinhibition and psychotic features. The cognitive and psychiatric components of the CCAS, together with the ataxic motor disability of cerebellar disorders, are conceptualized within the dysmetria of thought hypothesis. This concept holds that a universal cerebellar transform facilitates automatic modulation of behavior around a homeostatic baseline, and the behavior being modulated is determined by the specificity of anatomic subcircuits, or loops, within the cerebrocerebellar system. Damage to the cerebellar component of the distributed neural circuit subserving sensorimotor, cognitive, and emotional processing disrupts the universal cerebellar transform, leading to the universal cerebellar impairment affecting the lesioned domain. The universal cerebellar impairment manifests as ataxia when the sensorimotor cerebellum is involved and as the CCAS when pathology is in the lateral hemisphere of the posterior cerebellum (involved in cognitive processing) or in the vermis (limbic cerebellum). Cognitive and emotional disorders may accompany cerebellar diseases or be their principal clinical presentation, and this has significance for the diagnosis and management of patients with cerebellar dysfunction.

Mind-wandering is the focus of extensive investigation, yet until recently there has been no validated scale to directly measure trait levels of task-unrelated thought. Scales commonly used to assess mind-wandering lack face validity, measuring related constructs such as daydreaming or behavioral errors. Here we report four studies validating a Mind-Wandering Questionnaire (MWQ) across college, high school, and middle school samples. The 5-item scale showed high internal consistency, as well as convergent validity with existing measures of mind-wandering and related constructs. Trait levels of mind-wandering, as measured by the MWQ, were correlated with task-unrelated thought measured by thought sampling during a test of reading comprehension. In both middle school and high school samples, mind-wandering during testing was associated with worse reading comprehension. By contrast, elevated trait levels of mind-wandering predicted worse mood, less life-satisfaction, greater stress, and lower self-esteem. By extending the use of thought sampling to measure mind-wandering among adolescents, our findings also validate the use of this methodology with younger populations. Both the MWQ and thought sampling indicate that mind-wandering is a pervasive—and problematic—influence on the performance and well-being of adolescents.

This study investigated the validity of the Baecke Questionnaire, the Five City Project Questionnaire, and the Tecumseh Community Health Study Questionnaire in 19 Flemish males, using correlation and multiple stepwise regression analyses. The three questionnaires are commonly used physical activity questionnaires in epidemiological studies. The physical activity level (PAL) as measured with the doubly labelled water method was used as the criterion. The Baecke total activity index showed the highest correlation coefficient with PAL (r = 0.69, p < 0.001). Also the sweat index from the Five City Project Questionnaire, and total daily energy expenditure from the Tecumseh Community Health Study Questionnaire showed significant associations with PAL, respectively 0.57 (p < 0.05) and 0.64 (p < 0.01). Multiple stepwise regression analyses supported the findings from the correlation study. The largest individual contribution in PAL was from the activity index (45%) for the Baecke Questionnaire, the sweat index (29%) for the Five City Project Questionnaire, and total daily energy expenditure (38%) for the Tecumseh Community Health Study Questionnaire. In conclusion, the questionnaires, and certainly the Baecke Questionnaire, can provide valid data about physical activity. Therefore they are useful in epidemiological studies. PMID:10452224

To address calls for context-specific measurement of social support, this article reports the development of the Athletes' Received Support Questionnaire (ARSQ) and demonstrates initial evidence for its validity. Across four studies there was support for a four-dimensional structure reflecting emotional, esteem, informational, and tangible received support. There was also support for unidimensional and higher-order models. Further, Study 3 provided some support for convergent validity, with significant correlations between the corresponding dimensions of the ARSQ and the Inventory of Socially Supportive Behaviors. Study 4 provided evidence for the nomological validity of the ARSQ. Emotional and esteem support significantly predicted self-confidence and positive affect, and tangible support significantly moderated the relationship between stress and negative affect. Collectively, these results provide initial evidence for the validity of the ARSQ, and offer researchers flexibility to adopt either a multidimensional or aggregated approach to measuring received support.

Background Early treatment of COPD exacerbations has shown to be important. Despite a non-negligible negative impact on health related quality of life, a large proportion of these episodes is not reported (no change in treatment). Little is known whether (low burden) strategies are able to capture these unreported exacerbations. Methods The Clinical COPD Questionnaire (CCQ) is a short questionnaire with great evaluative properties in measuring health status. The current explorative study evaluates the discriminative properties of weekly CCQ assessment in detecting exacerbations. Results In a multicentre prospective cohort study, 121 patients, age 67.4 ± 10.5 years, FEV1 47.7 ± 18.5% pred were followed for 6 weeks by daily diary card recording and weekly CCQ assessment. Weeks were retrospectively labeled as stable or exacerbation (onset) weeks using the Anthonisen symptom diary-card algorithm. Change in CCQ total scores are significantly higher in exacerbation-onset weeks, 0.35 ± 0.69 compared to -0.04 ± 0.37 in stable weeks (p < 0.001). Performance of the ? CCQ total score discriminating between stable and exacerbation onset weeks was sufficient (area under the ROC curve 0.75). At a cut off point of 0.2, sensitivity was 62.5 (50.3-73.4), specificity 82.0 (79.3-84.4), and a positive and negative predictive value of 43.5 (35.0-51.0) and 90.8 (87.8-93.5), respectively. Using this cut off point, 22 (out of 38) unreported exacerbations were detected while 39 stable patients would have been false positively 'contacted'. Conclusions Weekly CCQ assessment is a promising, low burden method to detect unreported exacerbations. Further research is needed to validate discriminative performance and practical implications of the CCQ in detecting exacerbations in daily care.
In this paper, we propose a system for automatic design of magazine covers that quantifies a number of concepts from art and aesthetics. Our solution to automatic design of this type of media has been shaped by input from professional designers, magazine art directors and editorial boards, and journalists. Consequently, a number of principles in design and rules in designing magazine covers are delineated. Several techniques are derived and employed in order to quantify and implement these principles and rules in the format of a software framework. At this stage, our framework divides the task of design into three main modules: layout of magazine cover elements, choice of color for masthead and cover lines, and typography of cover lines. Feedback from professional designers on our designs suggests that our results are congruent with their intuition.

A new infinitely variable automatic transmission called the RESATRAN that automatically changes its speed ratio in response to load torque being transmitted is presented. A prototype has been built and tested on a conventional three-wheeled electric motor propelled wheelchair. It is shown theoretically that more than 50 percent reduction in power during hill climbing may be expected when a transmission-equipped wheelchair is compared to a direct-drive vehicle operating at the same voltage. It is suggested that with such a transmission, wheelchairs can use much smaller motors and associated electronic controls, while at the same time gaining in efficiency that results in longer operating distances for the same battery charge. Design details of the transmission and test results are presented. These results show a substantial reduction in operating current and increased distance of operation over a test course. PMID:3835264

Two problems must be solved if the finite element method is to become a reliable and affordable blackbox engineering tool. Finite element meshes must be generated automatically from computer aided design databases and mesh analysis must be made self-adaptive. The experimental system described solves both problems in 2-D through spatial and analytical substructuring techniques that are now being extended into 3-D.

During the past few years, automatic computer examination systems have been widely used for computer-based tests. But these systems are based on the traditional question-answer examination style which is limited for the collaborative examination. The collaborative examination needs multiple examinees and can be parallel performed. The collaborative examination also should consider the context of the examinee, e.g. the order of

The Machine Aided Voice Translation (MAVT) system was developed in response to the shortage of experienced military field interrogators with both foreign language proficiency and interrogation skills. Combining speech recognition, machine translation, and speech generation technologies, the MAVT accepts an interrogator's spoken English question and translates it into spoken Spanish. The spoken Spanish response of the potential informant can then be translated into spoken English. Potential military and civilian applications for automatic spoken language translation technology are discussed in this paper.

While the influence of Hispanic humoral medicine on 16th century and subsequent Mesoamerican indigenous thought is undeniable, recent reexaminations of Aztec, Mayan and Zapotec medicinal and cosmological systems suggest indigenous roots in hot-cold concepts. This paper reviews and compares the growing evidence for independent hot-cold classifications in Mesoamerica, and suggests certain common lines of syncretism in structure, content and applications. Drawing on a model from cognitive psychology previously applied by the author to hot-cold data of the Mitla Zapotec, the paper explores its utility for cross-cultural comparison of hot-cold category development.

In this report we describe a patient with a clinical diagnosis of dementia with Lewy bodies, who had hallucinations of reading her thoughts in the air although she was alexic and unable to read. She also had severe visuoperceptual deficits and closing-in phenomenon. SPECT imaging demonstrated hypoperfusion of the left parieto-occipital cortices together with hyperperfusion of the left orbitofronto-temporal areas. Her visual text hallucinations may represent another type of textual hallucinations related to syntacto-semantic network hyperactivation, which is implicated in auditory hallucinations in schizophrenia. PMID:24530173
The neuropathology underlying dementia syndromes in older populations is complex. The contributions of Alzheimer’s and Lewy body pathology are well appreciated. Recent studies with brain autopsies have highlighted the high prevalence of vascular disease as an independent, but often co-morbid contributor to dementia. The Adult Changes in Thought Study is a community-based, longitudinal study of brain aging and cognitive decline which has recently confirmed cerebral microinfarcts as a strong correlate of cognitive impairment and dementia. This study examines correlations between clinical characteristics including extensive, longitudinal medication histories, and longitudinal cognitive testing against structural and biochemical features of disease. Keywords: Aging, community-based, microinfarct, longitudinal, neuropathology.

We are developing a sensor camera system for automatically tracking and determining the positions of subjects moving in three-dimensions. The system is intended to operate even within areas as large as soccer fields. The system measures the 3D coordinates of the object while driving the pan and tilt movements of camera heads, and the degree of zoom of the lenses. Its principal feature is that it automatically zooms in as the object moves farther away and out as the object moves closer. This maintains the area of the object as a fixed position of the image. This feature makes stable detection by the image processing possible. We are planning to use the system to detect the position of a soccer ball during a soccer game. In this paper, we describe the configuration of the developing automatic tracking sensor camera system. We then give an analysis of the movements of the ball within images of games, the results of experiments on method of image processing used to detect the ball, and the results of other experiments to verify the accuracy of an experimental system. These results show that the system is sufficiently accurate in terms of obtaining positions in three-dimensions.
Automatic contrail detection is of major importance in the study of the atmospheric effects of aviation. Due to the large volume of satellite imagery, selecting contrail images for study by hand is impractical and highly subject to human error. It is far better to have a system in place that will automatically evaluate an image to determine 1) whether it contains contrails and 2) where the contrails are located. Preliminary studies indicate that it is possible to automatically detect and locate contrails in Advanced Very High Resolution Radiometer (AVHRR) imagery with a high degree of confidence. Once contrails have been identified and localized in a satellite image, it is useful to segment the image into contrail versus noncontrail pixels. The ability to partition image pixels makes it possible to determine the optical properties of contrails, including optical thickness and particle size. In this paper, we describe a new technique for segmenting satellite images containing contrails. This method has good potential for creating a contrail climatology in an automated fashion. The majority of contrails are detected, rejecting clutter in the image, even cirrus streaks. Long, thin contrails are most easily detected. However, some contrails may be missed because they are curved, diffused over a large area, or present in short segments. Contrails average 2-3 km in width for the cases studied.

Background: The fear of a shortage of physicians in some regions of Germany is growing. A drain of physicians into non-clinical activities is being discussed as a possible reason. To counteract this drain the extent of physicians' thinking about leaving patient care and the corresponding reasons need to be elucidated. Methods: All physicians upto 40 years of age and registered with the State Chamber of Physicians of Saxony (n=5?956) received a paper-pencil questionnaire inquiring about socio-demographics, job satisfaction, thinking about leaving patient care, and corresponding reasons. Reponse rate was 40% (n=2?357). Results: Nearly a quarter of the physicians working in patient care thought about leaving pa-tient care. Practicing in a hospital and having children were significantly associated with think-ing about leaving patient care. The main reasons were poor compatibility of profession and family, high burden due to shifts, poor compatibility of profession and private interests, high work load, and frequent overtime hours. Conclusions: Development and implementation of measures preventing especially long-term or permanent leave is crucial. Approaches enabling physicians to reconcile work and family play a special role.

A rule-based control and its application in functional electrical stimulation (FES) assisted walking of subjects with paraplegia are described in this paper. The design of rules for control comprises the following two steps: (1) determination of muscle activation patterns by using a fully customized spatial (3D) model of paraplegic walking, and (2) learning of rules, that is, correlation between the muscle activation patterns and kinematics of walking by means of an artificial neural network. The adopted FES system activated eight muscle groups with surface electrodes. The only joints allowing movement in the coronal plane were the hips, and externally controlled joints in sagittal plane were ankles, knees and hips. The simulation minimized the tracking error of the joint angles and the total activation of all eight muscles being stimulated. A radial-basis function artificial neural network was applied for learning of rules. Three automatically controlled modes (slow, near-normal, and near-ballistic) and hand-controlled walking were evaluated in six subjects with a complete spinal cord lesion (T8-T10). The performance of walking was assessed by the following: (1) energy consumption based on oxygen uptake, (2) physiological cost index, (3) maximum speed of walking, and (4) a questionnaire. The results showed that all modes of walking are achievable and that automatic control leads to more efficient and faster walking. The speed of walking achieved by automatic control was almost three times bigger compared with the speed of hand-controlled walking. The energy cost and rate decreased significantly when automatic control was applied; yet, they were still much bigger than the values measured in able-bodied subjects. The objective outcome measures suggest that the near-ballistic walking was the most effective, yet a questionnaire shows that most subjects preferred slow walking. The most likely reason for the preference of lower efficiency walking over the faster end energy efficient near-ballistic walking was that paraplegic patients had difficulties in synchronizing the voluntary movement of the trunk and arms to the artificially controlled movements of legs.

In this AMEE Guide, we consider the design and development of self-administered surveys, commonly called questionnaires. Questionnaires are widely employed in medical education research. Unfortunately, the processes used to develop such questionnaires vary in quality and lack consistent, rigorous standards. Consequently, the quality of the questionnaires used in medical education research is highly variable. To address this problem, this AMEE Guide presents a systematic, seven-step process for designing high-quality questionnaires, with particular emphasis on developing survey scales. These seven steps do not address all aspects of survey design, nor do they represent the only way to develop a high-quality questionnaire. Instead, these steps synthesize multiple survey design techniques and organize them into a cohesive process for questionnaire developers of all levels. Addressing each of these steps systematically will improve the probabilities that survey designers will accurately measure what they intend to measure.

The metaparadigm concept of person as a core emphasis for nursing theorizing has attracted considerable attention in western literature, but has received less attention in the context of eastern philosophical contexts. In this philosophical inquiry, we sought to clarify the concept of what it is to be a human being according to ideas deriving from Islamic tradition, drawing on concept analysis as general approach to advance an understanding of how nursing within an Islamic context might operationalize metaparadigm conceptualization. Specifically, we considered person as human being on the basis of its definition, attributes/characteristics and boundaries to explore the anatomy of the concept in this context. Our analysis revealed that Islamic thought is relevant to two distinct understandings of the holistic concept of human being. Reciprocal interaction worldview organizes the dimensions of being human (cognitive, emotion, social and spiritual) into a whole. Simultaneous action worldview emphasizes that the human is a coherent and unified creature in harmony with the universe. In Islamic thought, these two worldviews are integrated and operate concurrently. Nurse-patient interactions arising from an integrated perspective that aligns both of these worldviews will allow for informed applications of knowledge to practice and enhanced patient care.

The vast amount of social media data that can be gathered from the internet coupled with workflows that utilize both commodity systems and massively parallel supercomputers, such as the Cray XMT, open new vistas for research to support health, defense, and national security. Computer technology now enables the analysis of graph structures containing more than 4 billion vertices joined by 34 billion edges along with metrics and massively parallel algorithms that exhibit near-linear scalability according to number of processors. The challenge lies in making this massive data and analysis comprehensible to an analyst and end-users that require actionable knowledge to carry out their duties. Simply stated, we have developed language and content agnostic techniques to reduce large graphs built from vast media corpora into forms people can understand. Specifically, our tools and metrics act as a survey tool to identify thought leaders' -- those members that lead or reflect the thoughts and opinions of an online community, independent of the source language.

Recent work has highlighted that the generation of thoughts unrelated to the current environment may be both a cause and a consequence of unhappiness. The current study used lag analysis to examine whether the relationship between self-generated thought and negative affect depends on the content of the thoughts themselves. We found that the emotional content could strongly predict subsequent mood (e.g. negative thoughts were associated with subsequent negative mood). However, this direct relationship was modulated by the socio-temporal content of the thoughts: thoughts that were past- and other-related were associated with subsequent negative mood, even if current thought content was positive. By contrast, future- and self-related thoughts preceded improvements of mood, even when current thought content was negative. These results highlight the important link between self-generated thought and mood and suggest that the socio-temporal content plays an important role in determining whether an individual's future affective state will be happy or sad.

The current study incorporated a life span perspective into existing theories of intrusive thoughts to examine age-related differences in the difficulty controlling intrusive thoughts, the distress following intrusive thought recurrences, and the meanings assigned to these recurrences. Younger (N = 51) and older (N = 49) community adults were randomly assigned to suppress (i.e., keep out of mind) or monitor an intrusive thought. Participants rated their positive and negative affect throughout engagement with the intrusive thought, and they also rated the meanings they gave to recurrences of their everyday intrusive thoughts. The results demonstrated that older adults tended to perceive greater difficulty with controlling the intrusive thought than younger adults despite the fact that they did not differ in the actual recurrence of the intrusive thought. With regard to distress, older adults experienced steadier levels of positive affect than younger adults throughout engagement with the intrusive thought. However, older adults also reported greater residual negative affect after engaging with the intrusive thought than younger adults. Finally, older and younger adults appeared to assign meanings to recurrences of intrusive thoughts in line with age-relevant concerns. Specifically, older adults were prone to interpret the recurrence of intrusive thoughts as a sign of cognitive decline, but they were less likely than younger adults to see intrusive thoughts as a sign of moral failure. Together, these results highlight a range of potential risk and protective factors in older adults for experiencing emotion dysregulation after intrusive thoughts. PMID:21707184
Objectives The Manchester–Oxford Foot Questionnaire (MOXFQ) is a validated 16-item, patient-reported outcome measure for evaluating outcomes of foot or ankle surgery. The original development of the instrument identified three domains. This present study examined whether the three domains could legitimately be summed to provide a single summary index score. Methods The MOXFQ and Short-Form (SF)-36 were administered to 671 patients before surgery of the foot or ankle. Data from the three domains of the MOXFQ (pain, walking/standing and social interaction) were subjected to higher order factor analysis. Reliability and validity of the summary index score was assessed. Results The mean age of the participants was 52.8 years (sd 15.68; 18 to 89). Higher order principle components factor analysis produced one factor, accounting for 74.7% of the variance. The newly derived single index score was found to be internally reliable (? = 0.93) and valid, achieving at least moderate correlations (r ? 0.5, p < 0.001) with related (pain/function) domains of the SF-36. Conclusions Analyses indicated that data from the MOXFQ can be presented in summary form. The MOXFQ summary index score (MOXFQ-Index) provides an overall indication of the outcomes of foot and ankle surgery. Furthermore, the single index reduces the number of statistical comparisons, and hence the role of chance, when exploring MOXFQ data.
Abstract Objective Both self-reported indicators of stress and hormones such as cortisol and corticotrophin-releasing hormone (CRH) have been examined in relation to preterm birth. Although these hormones have been interpreted as biomarkers of stress, it is unclear whether psychosocial measures are empirically associated with biomarkers of stress in pregnant women. Methods We analyzed data from 1,587 North Carolina pregnant women enrolled in the Pregnancy, Infection, and Nutrition study during 2000–2004 who provided at least one saliva sample for cortisol measurement or blood samples for CRH at 14–19 and 24–29 weeks' gestation. Cortisol measures were limited to those taken between 8 and 10 a.m. Perceived stress, state-trait anxiety, coping style, life events, social support, and pregnancy-specific anxiety were measured by questionnaires and interviews. Spearman correlations and multiple regressions were used to describe the relationship among the measures of stress. Results No correlations larger than r?=?0.15 were seen between reported psychosocial measures and cortisol or CRH. Women with demographic characteristics associated with poor pregnancy outcomes (unmarried, African-American, young, low pre-pregnancy body mass index) reported higher levels of stress but did not consistently have higher levels of stress hormones. Pre-eclampsia was associated with higher CRH, but not with higher cortisol. Conclusions The relationship between measurements of reported stress and biomarkers is not straightforward in large epidemiological studies of pregnancy.

Background Individual work performance is an important outcome measure in studies in the workplace. Nevertheless, its conceptualization and measurement has proven challenging. To overcome limitations of existing scales, the Individual Work Performance Questionnaire (IWPQ) was recently developed. The aim of the current study was to gain insight into the responsiveness of the IWPQ. Methods Data were used from the Be Active & Relax randomized controlled trial. The aim of the trial was to investigate the effectiveness of an intervention to stimulate physical activity and relaxation of office workers, on need for recovery. Individual work performance was a secondary outcome measure of the trial. In total, 39 hypotheses were formulated concerning correlations between changes on the IWPQ scales and changes on similar constructs (e.g., presenteeism) and distinct constructs (e.g., need for recovery) used in the trial. Results 260 Participants completed the IWPQ at both baseline and 12 months of follow-up. For the IWPQ scales, 23%, 15%, and 38%, respectively, of the hypotheses could be confirmed. In general, the correlations between change scores were weaker than expected. Nevertheless, at least 85% of the correlations were in the expected direction. Conclusions Based on results of the current study, no firm conclusions can be drawn about the responsiveness of the IWPQ. Several reasons may account for the weaker than expected correlations. Future research on the IWPQ’s responsiveness should be conducted, preferably in other populations and intervention studies, where greater changes over time can be expected.
Background Multiple sclerosis (MS) preferentially affects females at childbearing age. For this reason patients and treating physicians were frequently confronted with questions concerning family planning, pregnancy and birth. Objective The aim of this study was to evaluate the expertise about pregnancy related topics in multiple sclerosis of neurologists in private practice. Methods We developed a survey with 16 multiple choice questions about pregnancy related topics and sent it to neurologists in private practice in Berlin, Germany. Results 56 completed questionnaires were sent back. 54% of all questions were answered correctly, 21% of the questions were answered with “I don’t know”. Correct answers were more often given by physicians who treat more than 400 MS patients per year (p?=?0.001). Further positive associations were found for assumed relevance of the topic (p?=?0.002) and the degree of counseling (p<0.001). Conclusion To provide a comprehensive counseling, MS patients with desire for children should be counseled by physicians with a lot of experience in MS treatment.
A video questionnaire (VQ) for measuring asthma prevalence in adolescents was assessed for repeatability and validity in relation to bronchial hyperresponsiveness (BHR) (PD20 less than or equal to 7.8 mumol methacholine). Comparison was also made with a standard, self completed written questionnaire (SQ), based on the IUATLD Bronchial Symptoms Questionnaire, which included five questions seeking comparable data to those in the VQ. Both the VQ and SQ were administered to 707 schoolchildren (13-16 years), in whom English was the primary language. One hundred and six randomly selected children subsequently underwent bronchial challenge to methacholine. Both the sensitivity and specificity for BHR were higher for a combination of three or more positive responses to the VQ (0.73 and 0.88), than to the SQ (0.63 and 0.82), although these differences were not statistically significant (P = 0.24). When administered again after a two week interval, the VQ had a significantly higher (P = 0.03) coefficient of repeatability (0.79) than the SQ (0.50). We conclude that the VQ is a valid and reliable method of determining asthma prevalence, and propose that by providing data relatively free from biases due to language, culture, literacy or interviewing techniques it may be particularly useful when comparing asthma prevalence and severity in different populations.

In this thesis, we evaluate the front-end of Automatic Speech Recognition (ASR) systems, with respect to different types of spectral processing methods that are extensively used. A filter bank approach for front end spectral analysis is one of the common methods used for spectral analysis. In this work we describe and evaluate spectral analysis based on Mel and Gammatone filter banks. These filtering methods are derived from auditory models and are thought to have some advantages for automatic speech recognition work. Experimentally, however, we show that direct use of FFT spectral values is just as effective as using either Mel or Gammatone filter banks, provided that the features extracted from the FFT spectral values take into account a Mel or Mel-like frequency scale. It is also shown that trajectory features based on sliding block of spectral features, computed using either FFT or filter bank spectral analysis are considerably more effective, in terms of ASR accuracy, than are delta and delta-delta terms often used for ASR. Although there is no major performance disadvantage to using a filter bank, simplicity of analysis is a reason to eliminate this step in speech processing. These assertions hold for both clean and noisy speech.
The aim of this systematic review was to review the quality of the translation and the measurement properties from questionnaires that assess injuries of the knee. We included questionnaires that were developed in foreign language and have been translated and validated into Portuguese. The databases used were CINAHL, SPORTDiscus, LILACS, PUBMED and SCIELO and the final search resulted in a total of 868 studies included, from which 16 were eligible. Most included questionnaires presented all steps expected in a translation process; however there were some deficiencies in measurement properties among the questionnaires. The VISA-P Brazil was the best questionnaire when analyzing translation process and measurement properties tested. It was the only questionnaire that tested all measurement properties investigated and presented adequate values for all of them. KOS-ADLS was the best questionnaire translated to Portuguese from Portugal. Among all, the VISA-P Brazil is the best questionnaire to be used with Brazilian Portuguese speakers when the condition is related to patellar tendinopathy and the LEFS is the best questionnaire for other general conditions of the knee. For Portuguese from Portugal, the best questionnaire is the KOS-ADLS, and like the LEFS it does not target any specific injury.

In this paper, we develop a framework for using only the needed data for automatic target recognition (ATR) algorithms using the recently developed theory of sparse representations and compressive sensing (CS). We show how sparsity can be helpful for efficient utilization of data, with the possibility of developing real-time, robust target classification. We verify the efficacy of the proposed algorithm in terms of the recognition rate on the well known Comanche forward-looking infrared (FLIR) data set consisting of ten different military targets at different orientations.

New geologic mapping, geochemistry, argon dating, and paleomagnetic data suggest some significant new ideas about the history and evolution of Newberry Volcano. Previous mapping (MacLeod et al., 1995) made use of K-Ar dating done in the 1970's. A new 40Ar/39Ar age of 83±5 ka for the rhyolite of Paulina Peak, a thick lava flow cut by the southern caldera-bounding fault and previously thought to be hundreds of thousands of years old, indicates that the caldera formed since ˜83 ka. The ash-flow tuff (Qat) that forms the western rim of the caldera contains rhyodacitic pumices with unusually high Na2O (6.1 wt.%), identical in composition to a subset of pumices found in the underlying and more widespread basaltic lapilli tuff (Qbt), suggesting that these two ash-flow tuffs represent parts of the same eruptive event. Their paleomagnetic directions are very similar. Lapilli identical in composition and appearance to those in the Qbt are found in gravel underlying basalt that has been dated at about 80 ka. Taken together, the data suggest that the caldera formed about 80 ka when Qbt and Qat erupted. An earlier caldera likely formed about 300 ka, the approximate age of each of several mapped rhyolitic to dacitic ash-flow tuffs on the eastern side of the volcano, one of which was previously thought to be >500 ka in age. Preliminary paleomagnetic data suggest that these ash-flow tuffs have similar remnant directions. Previous identification (Kuehn, 2002) of some 40-50 Pleistocene tephras indicates either that Newberry is far more explosive than previously thought or that many of these tephras (of which no more than 6 occur in any single hand-dug pit) may represent different lobes of tephra generated by compositionally-zoned caldera-forming eruptions. The widespread Olema ash bed (a centimeter thick in the San Francisco Bay Area, ˜700 km SSW of Newberry Volcano) may represent one lobe of the ˜80-ka caldera-forming event. In the course of geologic mapping, 1- to 2-meter-sized boulders of a variety of lava flow types have been found on the tops of cinder cones at elevations as low as 5782 feet. Interpreted as glacial erratics, they suggest that ice extended far down the flanks of the volcano, rather than forming only very small cirques and limited moraines at the caldera rim (highest elevation 7984 feet), as previously thought. Large areas of mixed pumice and gravel at higher elevations may represent till that grades into outwash gravel at lower elevations. Periodic outburst floods from lakes formed in or beneath the ice cap (possibly linked to eruptive activity?) would explain the large channels that are so abundant on the eastern and, to a lesser extent, on the western (and younger) side of the volcano. As many as half a dozen postglacial (< ˜12 ka?), but pre-Mazama ( ˜8 ka), basaltic lava flows occupy several of the eastern and southeastern dry channels. The dry channels on the NE side appear to drain into the canyon of Dry River, a large, dry box canyon several hundred feet deep, which may have been carved by multiple large floods originating primarily from Newberry Volcano.

We introduce a series of activities to help students understand the partial derivatives that arise in thermodynamics. Students construct thought experiments that would allow them to measure given partial derivatives. These activities are constructed with a number of learning goals in mind, beginning with helping students to learn to think of thermodynamic quantities in terms of how one can measure or change them. A second learning goal is for students to understand the importance of the quantities held fixed in either a partial derivative or an experiment. Students additionally are given an experimental perspective—particularly when this activity is combined with real laboratory experiments—on the meaning of either fixing or changing entropy. In this paper, we introduce the activities and explain their learning goals. We also include examples of student work from classroom video and follow-up interviews.
The guest editors identified eleven prominent public health thought leaders from practice, academia, professional associations, and philanthropic organizations to be interviewed for their opinions about the future of public health, the skills needed by the public health workforce, and training opportunities and roles. While they spoke from many different perspectives, several overarching themes emerged. The public health workforce needs updated skills. Public health academia should be more engaged in educating and training for public health practice, which would also benefit academia. There is a sense that "now is the time" for public health to be an essential player in the health care system. They see promise in emerging activities such as accreditation, practice-based research, and an explicit national agenda for workforce training. Overall, they are cautiously optimistic about the potential for greater real and perceived value of public health, momentum for more comprehensive, and coordinated public health training.

Several software systems are available for implementing automatic differentiation of computer programs. The forward mode of automatic differentiation is limited by computational intensity and computer memory. The reverse mode, or adjoint approach, is limited by computer memory and disk storage. A modular technique for derivative computation that can significantly reduce memory required to compute derivatives in a complex FORTRAN model using the reverse mode of automatic differentiation is discussed and demonstrated.

NCI developed a new instrument called the NHANES Food Frequency Questionnaire (formerly called Food Propensity Questionnaire) and supported its application in the National Health and Nutrition Examination Survey (NHANES). This instrument collects much of the same information as a food frequency questionnaire (FFQ), but without asking about portion size. The resulting data can be employed in the NCI usual dietary intakes model as covariates. By not asking about portion size, the NHANES FFQ requires less respondent burden than other FFQs.

Laser coagulation is a treatment method for many retinal diseases. Due to variations in fundus pigmentation and light scattering inside the eye globe, different lesion strengths are often achieved. The aim of this work is to realize an automatic feedback algorithm to generate desired lesion strengths by controlling the retinal temperature increase with the irradiation time. Optoacoustics afford non-invasive retinal temperature monitoring during laser treatment. A 75 ns/523 nm Q-switched Nd:YLF laser was used to excite the temperature-dependent pressure amplitudes, which were detected at the cornea by an ultrasonic transducer embedded in a contact lens. A 532 nm continuous wave Nd:YAG laser served for photocoagulation. The ED50 temperatures, for which the probability of ophthalmoscopically visible lesions after one hour in vivo in rabbits was 50%, varied from 63°C for 20 ms to 49°C for 400 ms. Arrhenius parameters were extracted as ?E=273 J mol(-1) and A=3 x 10(44) s(-1). Control algorithms for mild and strong lesions were developed, which led to average lesion diameters of 162 ± 34 ?m and 189 ± 34 ?m, respectively. It could be demonstrated that the sizes of the automatically controlled lesions were widely independent of the treatment laser power and the retinal pigmentation. PMID:22734753

The VARK Questionnaire "How Do I Learn Best?" is a very useful free learning styles survey tool. This questionnaire can help students better understand how they learn and how to best study depending upon their preferred learning style: visual, aural, kinesthetic, read-write or multimodal. After taking the questionnaire, the participant will receive a personal learning profile with learning and study hints specifically geared to their learning style. It also can help instructors find out how their students learn and the best ways to teach them. There is also a version of the questionnaire available for athletes or for younger people.
Cognitive models of obsessive-compulsive disorder (OCD) suggest that misinterpreting intrusive thoughts exacerbates obsessional thinking. To evaluate this hypothesis, healthy participants (N=91) were prompted to recollect their unwanted thoughts, and then beliefs about the immorality of these thoughts were manipulated. Next, participants completed implicit and explicit measures of self-evaluation and appraisals of unwanted thoughts. Results from structural regression analyses indicated that
Purpose of the research was to describe registered nurses' (RNs) (n?=?53) thoughts on the blended learning format in a 'specialist nursing programme in cancer care'. The study was conducted in autumn 2007 and 2008. A content analysis of answers to open-ended questions in a web-based questionnaire and a focus group interview were carried out. The analysis revealed that the RNs appreciated blended learning. The web lectures facilitated learning and gave RNs access to the education at any time. However, according to the RNs, knowledge is gained through interaction between RNs and teachers, and this aspect needed to be improved. The RNs also thought that the content of the seminars on campus should focus on evidence-based nursing knowledge and practical skills, not just taught as stable facts and procedures. The result from the present study could help to improve the design and content of advanced nursing courses using a blended learning format. PMID:24338502
Background Little is known about how positive phenomena can support resettlement of refugees in a new country. The aim of this study was to examine the hopeful thinking in a group of West African quota refugees at arrival and after 6 years in Sweden and compare these thoughts to the views of resettlement support professionals. Method The primary study population comprised 56 adult refugees and 13 resettlement professionals. Qualitative data were collected from the refugees by questionnaires on arrival and 6 years later. Data were collected from the resettlement professionals by interview about 3 years after arrival of the refugees. Snyder's cognitive model of hope was used to inform the comparative data analyses. Results Hopes regarding education were in focus for the refugees shortly after arrival, but thoughts on family reunion were central later in the resettlement process. During the later stages of the resettlement process, the unresponsiveness of the support organization to the family reunion problem became as issue for the refugees. The professionals reported a complex mix of "silent agency thoughts" underlying the local resettlement process as a contributing reason for this unresponsiveness. Conclusion Hopes regarding education and family reunion were central in the resettlement of West African refugees in Sweden. These thoughts were not systematically followed up by the support organization; possibly the resources for refugees were not fully released. More studies are needed to further investigate the motivational factors underpinning host community support of refugees' hopes and plans.
Principal components factor analyses with orthogonal rotation were performed on Importance, Sponge Agreement, Pill Agreement, and Diaphragm Agreement scales on the Contraceptive Attributes Questionnaire (CAQ) to ascertain reliability and validity. Specifically, the intent was to measure whether the scales included more than 1 dimension. Internal consistency of the factors was also measured with Cronbach's alpha for each of the factors in each of the Importance and Agreement factors. Data were obtained from a US national telephone survey of 1187 sexually active women 15-44 years. 385 were currently using the contraceptive sponge, 407 women who had formerly used the sponge, and 396 who had never used the sponge and were using other forms of contraception. 91.9% were white, 5.8% were black, and 1.4% were of Hispanic origin. 75.9% were employed outside the household. 61.4% were currently married, 25.2% were never married, and 13.4% were widowed or divorced. The instrument was designed to measure the subjective importance of specific attributed that contraceptive methods may have (Importance) and the perceived characteristics of specific contraceptive methods (Agreement). Importance is measured by the respondent's rating on a 5-point scale of how important each of 18 attributes was in selecting a birth control method. Agreement was determined by asking how much one agrees that the 18 attributes describes each of 3 methods: the pill, the sponge, and the diaphragm (14 attributes). The model of contraceptive decision making assumes that choice of a specific method is a function of value, importance, and likelihood. The attributes were based on 2 other sources, and pretesting reduces 63 items down to 18. The results yielded ratings of agreement for all 3 methods on convenience and absence of health problems and side effects attributes. For vaginal methods only, the attribute of greatest importance was convenience. The conclusion is that the subscales have reasonable internal consistency. In the comparison of women who used different methods, there were differences by user status on the ratings of the Importance and Agreement attributes for all 3 methods. Sponge users emphasized obtaining contraceptives without consulting medical staff. Pill users were concerned with the reputation of the method and convenience of use. Diaphragm users related to the reputation and familiarity with the method. Limitations were built into the sample which was not randomly selected, predominately white, and may reflect more innovative users. Items also were all stated in the positive. The CAQ would be useful is determining the characteristics of methods of importance to her and her perceptions of methods. Future research might examine different populations and compare positive and negative items. PMID:12344926

Background The co-occurring use of tobacco and marijuana among young people is a concern, yet little research has examined processes of co-use. Understanding expectancies around use of the two substances will help identify intervention targets. This study examined psychometric properties of the Nicotine and Marijuana Interaction Expectancy (NAMIE) questionnaire based on three modified scales of the Nicotine and Other Substance Interaction Expectancy (NOSIE) questionnaire. Method An anonymous online survey recruited participants (N=1152) age 18 to 25 (mean age 20 years, 67% male, 72% Caucasian) who reported use of cigarettes and marijuana in the past 30 days. Analyses examined reliability and validity of the NAMIE. Results A confirmatory factor analysis indicated good model fit for a 3-factor model. Scales were marijuana increases tobacco use and urges, tobacco increases marijuana use and urges, and smoking to cope with marijuana urges. Subscales correlated significantly with measures of cigarette smoking (r = .08 to .27, p<.01) and nicotine dependence (r = -.07 to -.20, p<.01), marijuana use (r = .08 to .29, p<.01) and dependence (r = .27 to .42, p<.01), percent of days using both cigarettes and marijuana in the past 30 days (r = .15 to .30, p<.01), thoughts about tobacco and marijuana abstinence (r = -.09 to .44, p<.01), and motivation to quit using marijuana (F = 9.43, p<.001). When entered into a regression model, variables of use and thoughts about use remained significant. Conclusions The NAMIE was well-adapted for use with a marijuana-using community sample of young adult smokers.

Objective: Habit might be usefully characterized as a form of automaticity that involves the association of a cue and a response. Three studies examined habitual automaticity in regard to different aspects of the cue-response relationship characteristic of unhealthy and healthy habits. Design, Main Outcome Measures, and Results: In each study, habitual automaticity was assessed by the Self-Report Habit Index (SRHI).
The Obsessive Beliefs Questionnaire-44 (OBQ-44), a self-report measure, was developed by the Obsessive Compulsive Cognitions Working Group (OCCWG) to assess beliefs considered relevant in the etiology and maintenance of obsessions and compulsions. The purpose of this study was to evaluate the psychometric properties of the Persian language version of the Obsessive Beliefs Questionnaire (POBQ-44). A sample of 222 medical students from an Iranian university was used to assess the reliability and validity of the POBQ-44. The results indicated five factors: 1) general, 2) perfectionism, certainty, 3) responsibility and threat estimation, 4) importance and control of thoughts, 5) complete performance. Each of these factors was found to have adequate test-retest and internal consistency reliability. Each of the factors was associated with O-C symptoms. In addition, adequate convergent validity was found with a measure of obsessive compulsive symptoms, and discriminate validity was found with measures of depression and anxiety. PMID:24658991
Development of some of the space program's large simulation projects -- like the project which involves simulating the countdown sequence prior to spacecraft liftoff -- requires the support of automated tools and techniques. The number of preconditions which must be met for a successful spacecraft launch and the complexity of their interrelationship account for the difficulty of creating an accurate model of the countdown sequence. Researchers developed ANPS for the Nasa Marshall Space Flight Center to assist programmers attempting to model the pre-launch countdown sequence. Incorporating the elements of automatic programming as its foundation, ANPS aids the user in defining the problem and then automatically writes the appropriate simulation program in GPSS/PC code. The program's interactive user dialogue interface creates an internal problem specification file from user responses which includes the time line for the countdown sequence, the attributes for the individual activities which are part of a launch, and the dependent relationships between the activities. The program's automatic simulation code generator receives the file as input and selects appropriate macros from the library of software modules to generate the simulation code in the target language GPSS/PC. The user can recall the problem specification file for modification to effect any desired changes in the source code. ANPS is designed to write simulations for problems concerning the pre-launch activities of space vehicles and the operation of ground support equipment and has potential for use in developing network reliability models for hardware systems and subsystems. ANPS was developed in 1988 for use on IBM PC or compatible machines. The program requires at least 640 KB memory and one 360 KB disk drive, PC DOS Version 2.0 or above, and GPSS/PC System Version 2.0 from Minuteman Software. The program is written in Turbo Prolog Version 2.0. GPSS/PC is a trademark of Minuteman Software. Turbo Prolog is a trademark of Borland International.

We report herein the results of the cross-cultural adaptation and validation into the Greek language of the parent's version of 2 health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Greek CHAQ CHQ were fully validated with 3 forward and 3 backward translations. A total of 143 subjects were enrolled: 82 patients with JIA (28% systemic onset, 24% polyarticular onset, 10% extended oligoarticular subtype, and 38% persistent oligoarticular subtype) and 61 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Greek version of the CHAQ-CHQ is a reliable, and valid tool for the functional, physical and psychosocial assessment of children with JIA. PMID:11510336

We report herein the results of the cross-cultural adaptation and validation into the Hungarian language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Hungarian CHAQ CHQ were fully validated with 3 forward and 3 backward translations. A total of 127 subjects were enrolled: 67 patients with JIA (13.5% systemic onset, 42% polyarticular onset, 13.5% extended oligoarticular subtype, and 31% persistent oligoarticular subtype) and 60 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Hungarian version of the CHAQ-CHQ is a reliable, and valid tool for the functional, physical and psychosocial assessment of children with JIA. PMID:11510337
The outcome expectancies of 250 respondents were examined using the Food Expectancy Questionnaire (FEQ), comparing expectancies about four different foods: fruit, vegetables, chocolate and sweets and plain biscuits. These expectancies were related to diet as assessed by a Food Frequency Questionnaire. As with alcohol expectancies [Jones, B. T., Corbin, W. & Fromme, K. (2001). A review of expectancy theory and alcohol consumption. Addiction, 96, 57-72], on which this research was modelled, positive and negative outcomes were the main factors for all foods, accounting jointly for between 33 and 40% of expectancy variance in factor analysis and predicting as much as 16% of the variance in relevant food intake measures by linear regression. Expected positive and negative outcomes of eating were predominantly immediate psychological after-effects, rather than including orosensory experiences, or longer-term effects on health or well-being. Other expectancies varied from food to food. FEQ expectancies for different foods have similar factor structure and were related to self-reported diet, the FEQ therefore shows promise as a means of modelling cognitions about eating.

We report herein the results of the cross-cultural adaptation and validation into the Bulgarian language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Bulgarian CHAQ CHQ were fully validated with 1 forward and 1 backward translations. 137 subjects were enrolled: 77 patients with JIA (36% systemic onset, 30% polyarticular onset, 4% extended oligoarticular subtype, and 30% persistent oligoarticular subtype) and 60 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Bulgarian version of the CHAQ-CHQ is a reliable, and valid tool for the functional, physical and psychosocial assessment of children with JIA. PMID:11510327
The risk of infections and malignancies is the major area of concern with anti-tumor necrosis factor (anti-TNF) agents. The aim of this study was to investigate patients' views about their treatments and the factors that influence patients' treatment decisions concerning the use of anti-TNF-? drugs. This descriptive study was conducted in a single rheumatology unit. Patients using anti-TNF-? drugs for at least 3 months were included. Patients' thoughts and perceptions about their treatment were evaluated using a questionnaire. A total of 101 (94.1 % male) patients were recruited. The patients described their feelings as hopeful, worried, happy, scared, desperate, and hopeless, with the order decreasing beginning with the first. Hope for healing and an expectation of increased quality of life were the most significant determinants for acceptance of treatment. After the drug information was given, patients described their feelings as follows: increase in anxiety, psychologically wearisome, and worrying about their condition worsening in the future. After anti-TNF-? treatment, patients described their experience as follows: "the most effective medicine that I have ever used," "it saved my life," "control procedures that were carried out before the treatment and once every 3 months after the treatment were essential," "I feel myself safe with these controls," and "I advised other people." This study, to our knowledge, is the first to evaluate the attitudes of patients concerning anti-TNF-? drugs from the stage of informed consent to the post-experience stage. We found that standard consent forms caused an increase in the level of anxiety among new users of anti-TNF-? drugs, although the aim was the exact opposite. The reasons for acceptance were the hope for healing, reliance on physicians, and advice of other patients. Most patients accepted follow-up control procedures, which aimed to diagnose adverse effects early. PMID:24374358
A new course was implemented at USI in the Fall 1997 semester. This course is neither a traditional physics course nor a traditional humanities course. It is a hybrid of the two. The course covers some of the important ideas in physics, particularly special relativity and quantum mechanics, and their relationship to other areas of human thought, e.g. philosophy, literature, and art. The emphasis of the course is on learning the physics and the significance of the ideas presented. Physical theories are framed in the context of the times in which they developed. The worldview of the physicist that results from these new ideas is explored, with discussion of how this worldview compares and contrasts to the worldview of other fields. Connections to other areas are made through readings, excerpted in the text as well as from outside sources. These readings are from works that have a direct connection to physics. The course involves both the solving of "traditional physics problems" and the writing of essays relating the ideas developed in the problems to a wider context. A description of the course will be presented along with a post-course analysis.
The enquiry of suicide is of particular importance. According to WHO statistics suicide in people aged from 15 to 24 years has shown the greatest increase of relative mortality. In the group of suicidal adolescents, depression, behavioural disorders, abuse of different substances and personality deviations are frequent factors in presence. The aim of our investigation was to determine the correlation between psychoactive substance abuse and the occurrence of suicidal thoughts in adolescents. The specific "Q 2000" test was used to question 600 adolescents, from Tuzla and Sarajevo Cantons, with the same gender and age distribution and rural-urban ambient. The more prevailing suicidal idea occurrence was observed in cannabis abusers (50.0%) and alcohol abusers (36.6%) in comparison to non-abusers regardless gender and/or living ambient (settlement types) (19.5% and 17.6% per each, x2 = 17.184 p = 0.00001). The augmentation in number of suicidal ideas was not observed in tobacco smokers. PMID:14528719
The poinsettia (Euphorbia pulcherrima) is a much-maligned plant which is thought by the public and some health professionals to be extremely toxic. Despite pronouncements by public health officials to the contrary, the poinsettia continues to be recognized as a poisonous plant. To determine if there was any validity to the toxicity claims, 849,575 plant exposures reported to the American Association of Poison Control Centers were electronically analyzed. Poinsettia exposures accounted for 22,793 cases and formed the subset that was analyzed to critically evaluate the morbidity and mortality associated with poinsettia exposures. There were no fatalities among all poinsettia exposures and 98.9% were accidental in nature, with 93.3% involving children. The majority of exposed patients (96.1%) were not treated in a health care facility and 92.4% did not develop any toxicity related to their exposure to the poinsettia. Most patients do not require any type of therapy and can be treated without referral to a health care facility. PMID:8906768
Divorce has been identified as a risk factor for suicide. However, little research has been conducted on the time trajectory of the influence of relationship separation on suicidal outcomes. This study aimed to assess the effects over time of relationship breakdown and separation on suicidality. Data were drawn from 6616 Australian adults participating in the PATH through Life Project, a population-based longitudinal study. Suicidal ideation was reported by 406 participants (6.1%), and 99 (1.5%) reported a suicide plan or attempt in the past year. The effects of separation on suicidality were strongest soon after separation, with a nearly three-fold increase in ideation (adjusted OR = 2.73, p < 0.001) and an eight-fold increase in plans/attempts (adjusted OR = 7.75, p < 0.001) in the two years following separation, gradually diminishing subsequently. The period up to four years before a separation was also found to be a time of increased risk for suicidal thoughts and behaviours, while marriage was protective. Separation is a strong risk factor for suicidality and mental health services should target recently separated individuals. PMID:24768777

Light is the one key essential quality of holography and as such holograms are morphologically closer to 'Optical', 'Kinetic' and 'Light Art'. In my attempt to explore this 'Kinetic' feature I collaborated Martin Richardson in the Modern Holography Program at DeMontfort University, in Leicester between March 2010 and 2011, to produce a series of digital art holograms and lenticulars with an open and experiential reference to light capture as energetic element. These holograms were filmed using a 35mm digital camera on a moving rail system and are as such 'Stereogram's', then printed by GEOLA in Lithuania as reflection holograms measuring 50cm x 60cm. The title of this series of digital stereographic holograms is 'Changing Thoughts'. They allude to the interrelationship the observer has in assuming an understanding of what they see, only to suddenly change when they find out that what they are seeing is actually something quite different to what they had understood. Much critical theorization, in recent times, has focused on the body and related to the work of Merleau-Ponty. And to António Damásio, the word images, means mental patterns with each sensorial way. Not only related at "visual" images nor static objects. But also sonorous images, or body inside images like those described by Einstein when he was trying to solve problems.
There has been a resurgence of interest for the field of cardiac metabolism catalysed by the increased need for new therapeutic targets for patients with heart failure. The primary focus of research in this area to date has been on the impact of substrate selection for oxidative energy metabolism; however, anaplerotic metabolism also has significant interest for its potential cardioprotective role. Anaplerosis refers to metabolic pathways that replenish the citric acid cycle intermediates, which are essential to energy metabolism; however, our understanding of the role and regulation of this process in the heart, particularly under pathophysiological conditions, is very limited. Therefore, the goal of this article is to provide a foundation for future directions of research on cardiac anaplerosis and heart disease. We include an overview of anaplerotic metabolism, a critical evaluation of current methods available for its quantitation in the intact heart, and a discussion of its role and regulation both in health and disease as it is currently understood based mostly on animal studies. We also consider genetic diseases affecting anaplerotic pathways in humans and acute intervention studies with anaplerotic substrates in the clinics. Finally, as future perspectives, we will share our thoughts about potential benefits and practical considerations on modalities of interventions targeting anaplerosis in heart disease, including heart failure.

A recent paper in this journal has criticized our previous study, in which we identified an adaptive significance of trunk inclination on slopes. Our main argument was that a tree on a slope may gain some benefit by leaning, which provides the tree with shorter access to the canopy light, and thus a better chance for survival, and that if this benefit outweighs the cost involved in leaning, trunk inclination will be favoured by selection. Although the criticisms are based on some misunderstandings, the situations considered in the critique, which are different from ours, have inspired us into an extension of our previous study. In the course of a reply to the criticisms, we present a further thought on the adaptive significance of trunk inclination in a broader scope. Specifically, we show that our model, with its modified formulation of the benefit component of tree leaning, may evaluate the fitness of a tree with its trunk inclined. It can also be used to examine the conditions for tree leaning, and make predictions on the optimal tree leaning in any situations, including canopy gaps and permanent openings, which the critique is mainly concerned with.
The author proposes an expanded notion of the concept of Agieren, introduced by Freud in his theory of transference, and to this effect discusses three metapsychological articulations. Firstly, the idea of the psyche is proposed containing different co-existing modalities of representing emotional experience. One is a verbal inscription governed by the logic of the dynamically repressed, and another is the registration of a mode of being, in the form of sequences of psychic gestures that the subject exchanges with his objects. The author proposes that the psychic gesture is the ideopictographic representation for certain emotional states never verbally thought and, consequently, its metapsychological status is unconscious but not repressed. Secondly, these unconscious registers contain specific modalities of processing reality, created by the projective attribution of the parental unconscious. Finally, by conceiving this model of unconscious, ideopictographically represented as psychic gestures, the author proposes that a patient's emotional state, becoming a psychic gesture of the analytic pair, is enacted within the analytic stage. His proposal departs from the frequent view of enactment as a result of the non-represented aspects of the psyche. It is assumed that what is played out by the analytic pair pertains to the unconscious imaginary represented. PMID:24102491
This study examined the frequency of suicidality based on self-report and parent report in 430 sexually abused outpatient youth ages 3 to 17. Thirty-four percent of youth experienced suicidal ideation or behavior. However, when both parent and child completed measures, the rate of suicidality increased to 45.3%. The prevalence of suicidal thoughts and behavior was not higher based on relationship to the perpetrator, race, or previous placement outside the home. Suicidal youth rated themselves as more depressed, anxious, and angry on self-reports. Child self-reports of post-traumatic stress disorder were greater among the suicidal youth. Parent reports of depression and post-traumatic stress disorder were greater among suicidal youth. A logistic regression model including Trauma Symptom Checklist for Children Depression and Anger scores correctly classified 74.2% of suicidal and nonsuicidal children and adolescents, but not self-criticism, was predicted by depression and anger. These findings support the need for formal multi-informant evaluations of suicidality in sexually abused youth. PMID:23829832
Web-based personal health records (PHRs) are being widely deployed. To improve PHR's capability and usability, we proposed the concept of intelligent PHR (iPHR). In this paper, we use automatic home medical product recommendation as a concrete application to demonstrate the benefits of introducing intelligence into PHRs. In this new application domain, we develop several techniques to address the emerging challenges. Our approach uses treatment knowledge and nursing knowledge, and extends the language modeling method to (1) construct a topic-selection input interface for recommending home medical products, (2) produce a global ranking of Web pages retrieved by multiple queries, and (3) provide diverse search results. We demonstrate the effectiveness of our techniques using USMLE medical exam cases. PMID:20703712
A commutated automatic gain control system (AGC) was designed and constructed for the prototype Loran C receiver. The AGC is designed to improve the signal-to-signal ratio of the received Loran signals. The AGC design does not require any analog to digital conversion and it utilizes commonly available components. The AGC consists of: (1) a circuit which samples the peak of the envelope of the Loran signal to obtain an AGC voltage for each of three Loran stations, (2) a dc gain circuit to control the overall gain of the AGC system, and (3) an AGC amplification of the input RF signal. The performance of the AGC system was observed in bench and flight tests; it has improved the overall accuracy of the receiver. Improvements in the accuracy of the time difference calculations to within approx. + or - 1.5 microseconds of the observed time differnces for a given position are reported.
The task of inferring a set of classes and class descriptions most likely to explain a given data set can be placed on a firm theoretical foundation using Bayesian statistics. Within this framework, and using various mathematical and algorithmic approximations, the AutoClass System searches for the most probable classifications, automatically choosing the number of classes and complexity of class descriptions. A simpler version of AutoClass has been applied to many large real data sets, has discovered new independently-verified phenomena, and has been released as a robust software package. Recent extensions allow attributes to be selectively correlated within particular classes, and allow classes to inherit, or share, model parameters through a class hierarchy. The mathematical foundations of AutoClass are summarized.
In the present study, we investigated whether luminance and the side of response execution are associated, showing a SNARC-like effect (faster responses with the left hand for dark stimuli, and vice versa for light stimuli). A total of 30 participants were tested in two experiments. In Experiment 1, the association between space and the luminance of chromatic stimuli was directly tested (brightness discrimination). In Experiment 2, the same spatial association was tested indirectly (hue discrimination). The results showed that participants responded faster with their left hand to hues with lower luminance, and with their right hand to hues with higher luminance, in either the direct or the indirect task. The consistency of this association in both tasks demonstrates the automaticity of the SNARC-like effect for luminance. PMID:24402699
Many problems associated with the development of nanotechnology require custom designed molecules. We use genetic graph software, a new development, to automatically evolve molecules of interest when only the requirements are known. Genetic graph software designs molecules, and potentially nanoelectronic circuits, given a fitness function that determines which of two molecules is better. A set of molecules, the first generation, is generated at random then tested with the fitness function, Subsequent generations are created by randomly choosing two parent molecules with a bias towards high scoring molecules, tearing each molecules in two at random, and mating parts from the mother and father to create two children. This procedure is repeated until a satisfactory molecule is found. An atom pair similarity test is currently used as the fitness function to evolve molecules similar to existing pharmaceuticals.
A wheel lighting device for illuminating a wheel of a vehicle to increase safety and enhance aesthetics. The device produces the appearance of a "ring of light" on a vehicle's wheels as the vehicle moves. The "ring of light" can automatically change in color and/or brightness according to a vehicle's speed, acceleration, jerk, selection of transmission gears, and/or engine speed. The device provides auxiliary indicator lights by producing light in conjunction with a vehicle's turn signals, hazard lights, alarm systems, and etc. The device comprises a combination of mechanical and electronic components and can be placed on the outer or inner surface of a wheel or made integral to a wheel or wheel cover. The device can be configured for all vehicle types, and is electrically powered by a vehicle's electrical system and/or battery.
