    Full Text Available The contribution of modern science to the progress of civilization is immeasurable. Even its tendency toward exclusive concentration on the objective world has had salutary effects of great value. Modern science has wiped away much that was merely superstitious or speculative. Its rejection of unfounded opinions and prejudices has helped the thinking mind question conventional beliefs, shed preferences and prejudices, and challenge established authority. But modern systems thinking inherited from natural science is the suppression of the subjective dimension of reality. Many complex systems are an attempt to define and represent all subjective experience in physical terms. The modern man has a bias towards objectivity. The powerful influence of sense impressions on his mind and thinking makes him ignore the subjective experience and consider only objective facts as a valid, legitimate and representation of reality. Observing objective factors that are physical is easier than observing subjective factors that are subtle. The mechanistic view of reality has led to the rejection of the role of the individual in social development as insignificant. The individuals determine the development of society. Their social power has its roots both in subjective factors and objective factors. Economy, politics, society, and culture are inseparable dimensions of a single integrated reality. Subject and object constitute an integrated whole. The mind sees them as separate and independent. Or it views one as completely subordinate to the other. Unbiased approach to the study of all human experiences may prove that subject and object are interdependent dimensions or elements of reality.

    objective test has only one correct answer, while subjective test has a range of possible answers. Because of this feature, reliability will not be difficult to achieve in the marking of the objective item, while the marking of the subjective items is reliable. On the whole, a good test must contain both subjective and objective test items.

    Background: Studies have not adequately compared subjective/objective ratings of female dermatology patients including patients presenting for cosmetic procedures. Objective: To examine objective versus subjective facial attractiveness ratings, demographic variables, and how men versus women judge female facial attractiveness. Methods: Sixty-five women (mean 42 years) presenting to a dermatology office. Subjects filled out a demographic and attractiveness questionnaire and were photographed. Four judges (2 male and 2 female) rated the photographs on a predefined 1 to 7 scale. Results: Mean subjective rating (subjects rating themselves) was 4.85 versus 3.61 for objective rating (judges rating subjects) (p<0.001). The mean age of subjects self-rating (subjective rating) who rated themselves in the 5 to 7 range was 39 years; the mean age of subjects self-rating (subjective rating) who rated themselves in the 3 to 4 range was 45 years (p=0.053). The mean age of subjects objectively rated by judges in the 5 to 7 range was 33 years; the mean age of subjects objectively rated by judges in the 3 to 4 range was 43 years (p<0.001); and the mean age of subjects objectively rated by judges in the 1 to 2 range was 50 years (p<0.001). The mean subjective rating (subjects rating themselves) for married women was 4.55 versus 5.27 for unmarried women (p=0.007); the mean objective rating (judges rating subjects) was 3.22 versus 4.15 (p<0.001). The mean objective rating by male judges was 3.09 versus 4.12 for female judges (p<0.001) Conclusion: Female patients presenting to a dermatology office rated themselves more attractive than did judges who viewed photographs of the subjects. Age and marital status were significant factors, and male judges rated attractiveness lower than female judges. Limitations of the study, implications, and suggestions for future research directions are discussed. PMID:21203353

  8. Psychology--tensions between objectivity and subjectivity.

    The self is often defined in terms of its presentational appearances. This may easily end up in a denial of the internal aspects of the self, which is very often related to a tendency to avoid the tension between the internal and the external, but also between subjectivity and objectivity. In this paper this ambition is regarded in a historical perspective, in which Fichte and Hegel both represent attempts at abolishing the tension, whereas Kant and Kierkegaard represent the opposite. History shows that an eradication of the tension between subjectivity and objectivity implies a deterioration of psychology as well. Thus the conclusion is that psychology is primarily to be defined in terms of the tension between subjectivity and objectivity, which requires an accurate understanding and the inclusion of both of them.

  9. Reduction of Subjective and Objective System Complexity

    Watson, Michael D.

    2015-01-01

    Occam's razor is often used in science to define the minimum criteria to establish a physical or philosophical idea or relationship. Albert Einstein is attributed the saying "everything should be made as simple as possible, but not simpler". These heuristic ideas are based on a belief that there is a minimum state or set of states for a given system or phenomena. In looking at system complexity, these heuristics point us to an idea that complexity can be reduced to a minimum. How then, do we approach a reduction in complexity? Complexity has been described as a subjective concept and an objective measure of a system. Subjective complexity is based on human cognitive comprehension of the functions and inter relationships of a system. Subjective complexity is defined by the ability to fully comprehend the system. Simplifying complexity, in a subjective sense, is thus gaining a deeper understanding of the system. As Apple's Jonathon Ive has stated," It's not just minimalism or the absence of clutter. It involves digging through the depth of complexity. To be truly simple, you have to go really deep". Simplicity is not the absence of complexity but a deeper understanding of complexity. Subjective complexity, based on this human comprehension, cannot then be discerned from the sociological concept of ignorance. The inability to comprehend a system can be either a lack of knowledge, an inability to understand the intricacies of a system, or both. Reduction in this sense is based purely on a cognitive ability to understand the system and no system then may be truly complex. From this view, education and experience seem to be the keys to reduction or eliminating complexity. Objective complexity, is the measure of the systems functions and interrelationships which exist independent of human comprehension. Jonathon Ive's statement does not say that complexity is removed, only that the complexity is understood. From this standpoint, reduction of complexity can be approached

  10. Objective and subjective time in anthropic reasoning

    CERN Document Server

    Carter, Brandon

    2007-01-01

    The original formulation of the (weak) anthropic principle was prompted by a question about objective time at a macroscopic level, namely the age of the universe when ``anthropic'' observers such as ourselves would be most likely to emerge. Theoretical interpretation of what one observes requires the theory to indicate what is expected, which will commonly depend on where, and particularly when, the observation can be expected to occur. In response to the question of where and when, the original version of the anthropic principle proposed an {it a priori} probability weighting proportional to the number of ``anthropic'' observers present. The present discussion takes up the question of the time unit characterising the biological clock controlling our subjective internal time, using a revised alternative to a line of argument due to Press, who postulated that animal size is limited by the brittleness of bone. On the basis of a static support condition depending on the tensile strength of flesh rather than bone...

  12. The subjective experience of object recognition: comparing metacognition for object detection and object categorization.

    Perceptual decisions seem to be made automatically and almost instantly. Constructing a unitary subjective conscious experience takes more time. For example, when trying to avoid a collision with a car on a foggy road you brake or steer away in a reflex, before realizing you were in a near accident. This subjective aspect of object recognition has been given little attention. We used metacognition (assessed with confidence ratings) to measure subjective experience during object detection and object categorization for degraded and masked objects, while objective performance was matched. Metacognition was equal for degraded and masked objects, but categorization led to higher metacognition than did detection. This effect turned out to be driven by a difference in metacognition for correct rejection trials, which seemed to be caused by an asymmetry of the distractor stimulus: It does not contain object-related information in the detection task, whereas it does contain such information in the categorization task. Strikingly, this asymmetry selectively impacted metacognitive ability when objective performance was matched. This finding reveals a fundamental difference in how humans reflect versus act on information: When matching the amount of information required to perform two tasks at some objective level of accuracy (acting), metacognitive ability (reflecting) is still better in tasks that rely on positive evidence (categorization) than in tasks that rely more strongly on an absence of evidence (detection).

  14. Referential Subject and Object Gaps in Modern Icelandic

    Directory of Open Access Journals (Sweden)

    Marianne Pouplier

    2004-01-01

    Full Text Available This paper investigates the nature of subject and object gaps in coordinate structures in Modern Icelandic. Modern Icelandic is considered to be a semi-pro-drop language, since it generally licenses only generic null subjects; object gaps only occur in the form of topic drop. Nevertheless it has been argued that MI licenses referential subject pro as well as referential object pro in certain (tightly restricted contexts. This assumption is based on the existence of coordinating constructions that exhibit referential subject and object gaps at the same time. While this paper follows previous proposals in assuming subject pro to be licit in coordinate structures, object argument gaps are assumed to be object-topic drop, which is independetly needed in the grammar of Icelandic. Under the analysis presented here, the previously reported null subject condition on null objects falls out from Icelandic word order facts.

  15. Subjective Wellbeing, Objective Wellbeing and Inequality in Australia.

    Western, Mark; Tomaszewski, Wojtek

    2016-01-01

    In recent years policy makers and social scientists have devoted considerable attention to wellbeing, a concept that refers to people's capacity to live healthy, creative and fulfilling lives. Two conceptual approaches dominate wellbeing research. The objective approach examines the objective components of a good life. The subjective approach examines people's subjective evaluations of their lives. In the objective approach how subjective wellbeing relates to objective wellbeing is not a relevant research question. The subjective approach does investigate how objective wellbeing relates to subjective wellbeing, but has focused primarily on one objective wellbeing indicator, income, rather than the comprehensive indicator set implied by the objective approach. This paper attempts to contribute by examining relationships between a comprehensive set of objective wellbeing measures and subjective wellbeing, and by linking wellbeing research to inequality research by also investigating how subjective and objective wellbeing relate to class, gender, age and ethnicity. We use three waves of a representative state-level household panel study from Queensland, Australia, undertaken from 2008 to 2010, to investigate how objective measures of wellbeing are socially distributed by gender, class, age, and ethnicity. We also examine relationships between objective wellbeing and overall life satisfaction, providing one of the first longitudinal analyses linking objective wellbeing with subjective evaluations. Objective aspects of wellbeing are unequally distributed by gender, age, class and ethnicity and are strongly associated with life satisfaction. Moreover, associations between gender, ethnicity, class and life satisfaction persist after controlling for objective wellbeing, suggesting that mechanisms in addition to objective wellbeing link structural dimensions of inequality to life satisfaction.

  16. Radical behaviorism and the subjective-objective distinction.

    1995-01-01

    The distinction between subjective and objective domains is central to traditional psychology, including the various forms of mediational stimulus-organism-response neobehaviorism that treat the elements of a subjective domain as hypothetical constructs. Radical behaviorism has its own unique perspective on the subjective-objective distinction. For radical behaviorism, dichotomies between subjective and objective, knower and known, or observer and agent imply at most unique access to a part of the world, rather than dichotomous ontologies. This perspective leads to unique treatments of such important philosophical matters as (a) dispositions and (b) the difference between first- and third-person psychological sentences.

    2014-09-01

    Full Text Available Objectives: When a person speaks, voice problems usually include pain or discomfort and/or difficulties in terms of the pitch, the loudness and the quality of the voice. When patients with voice problems induced by stroke, Parkinson’s disease, and systemic diseases involving the voice are examined, generally, of the Four Diagnoses (四診, a Diagnosis of Hearing can be used in current Korean medicine. The effects of acupuncture and herb medicine on voice problems have been reported for over 20 years. However, when it comes to improvements, objective and subjective evaluation methods need to be explained. Methods: Subjective methods for evaluating voice were studied through a literature search of old medicinal books containing Korean medicine diagnostics, and an objective evaluation method using Praat software is presented. Results: Korean medicine doctors analyze the patient’s voice in clinical settings unconsciously on a daily basis. However, most voice diagnoses depend on the doctor’s subjective evaluation. Voice qualities can be evaluated by using the Eight Principles (八綱, including Yin-Yang; the Five Elements (Phases; the Grade, Roughness, Breathy, Asthenic, Strained (GRBAS score, and the Visual Analogue Scale (VAS as subjective methods, and an acoustic analysis using the Praat program can be used as an objective method. Conclusion: A more complete voice examination can be achieved by using subjective and objective methods at the same time. For an objective explanation and management of patient’s voice problems or systemic disorders, an objective method should be used in Korean medicine, which already has many subjective diagnostic methods. More research needs to be conducted, and more clinical evidence needs to be collected in the future.

  19. Subjective vs. objective measures in the valuation of water quality.

    2013-11-30

    Environmental valuation studies rely on accurate descriptions of the current environmental state and its change. Valuation scenario can be based on objective quality measures described to respondents, on individual subjective perceptions or their combination. If subjective perceptions differ systematically from objective measures, valuation results may be biased. We examine the factors underlying the divergence between perceptions of water quality among summer house owners and the objective water quality classification. We use bivariate probit and multinomial logit models to identify factors that explain both the divergence between perceived and objectively measured water quality and its direction, paying special attention to variables essential in valuation, including those describing the respondent, the summer house and the water body. Some 50% of the respondents perceive water quality differently from the objective quality measures. Several factors are identified behind systematic differences between the perceived and objectively measured quality, in particular the water body type, the level of the objective quality classification and the travel distance to the site. The results emphasize the need to take individual perceptions into account in addition to objective measures in valuation studies, especially if the environmental quality of the study area differs considerably from the average quality in general.

  4. Beyond Objectivity and Subjectivity: The Intersubjective Foundations of Psychological Science.

    Mascolo, Michael F

    2016-12-01

    The question of whether psychology can properly be regarded as a science has long been debated (Smedslund in Integrative Psychological & Behavioral Science, 50, 185-195, 2016). Science is typically understood as a method for producing reliable knowledge by testing falsifiable claims against objective evidence. Psychological phenomena, however, are traditionally taken to be "subjective" and hidden from view. To the extent that science relies upon objective observation, is a scientific psychology possible? In this paper, I argue that scientific psychology does not much fail to meet the requirements of objectivity as much as the concept of objectivity fails as a methodological principle for psychological science. The traditional notion of objectivity relies upon the distinction between a public, observable exterior and a private, subjective interior. There are good reasons, however, to reject this dichotomy. Scholarship suggests that psychological knowledge arises neither from the "inside out" (subjectively) nor from the outside-in (objectively), but instead intersubjective processes that occur between people. If this is so, then objectivist methodology may do more to obscure than illuminate our understanding of psychological functioning. From this view, we face a dilemma: Do we, in the name of science, cling to an objective epistemology that cuts us off from the richness of psychological activity? Or do we seek to develop a rigorous intersubjective psychology that exploits the processes through which we gain psychological knowledge in the first place? If such a psychology can produce systematic, reliable and useful knowledge, then the question of whether its practices are "scientific" in the traditional sense would become irrelevant.

  5. Subjective and objective effects of coffee consumption - caffeine or expectations?

    2015-03-01

    Impact of 5 mg/kg caffeine, chance of receiving caffeine (stimulus expectancies), and expectations of effects of caffeine (response expectancies) on objective (heart rate (HR), systolic/diastolic blood pressure (SBP/DBP), measures of heart rate variability (HRV), and reaction time (RT)) and subjective variables were investigated in a double-blind, placebo-controlled experiment with a no-treatment group. Participants were 107 undergraduate university students (mean age 22.3 ± 3.96 years). Consumption of 5 mg/kg caffeine had an impact on participants' SBP, standard deviation of normal heartbeat intervals, HR (decrease), and subjective experience 40 minutes later even after controlling for respective baseline values, stimulus and response expectancies, and habitual caffeine consumption. No effects on DBP, high frequency component of HRV, the ratio of low- and high-frequency, and RT were found. Beyond actual caffeine intake, response expectancy score was also a determinant of subjective experience which refers to a placebo component in the total effect. Actual autonomic (SBP, HR) changes and somatosensory amplification tendency, however, had no significant impact on subjective experience. Placebo reaction plays a role in the subjective changes caused by caffeine consumption but it has no impact on objective variables. Conditional vs deceptive administration of caffeine (i.e. stimulus expectancies) had no impact on any assessed variable.

  6. Objective and Subjective Assessment of Digital Pathology Image Quality

    2015-03-01

    Full Text Available The quality of an image produced by the Whole Slide Imaging (WSI scanners is of critical importance for using the image in clinical diagnosis. Therefore, it is very important to monitor and ensure the quality of images. Since subjective image quality assessments by pathologists are very time-consuming, expensive and difficult to reproduce, we propose a method for objective assessment based on clinically relevant and perceptual image parameters: sharpness, contrast, brightness, uniform illumination and color separation; derived from a survey of pathologists. We developed techniques to quantify the parameters based on content-dependent absolute pixel performance and to manipulate the parameters in a predefined range resulting in images with content-independent relative quality measures. The method does not require a prior reference model. A subjective assessment of the image quality is performed involving 69 pathologists and 372 images (including 12 optimal quality images and their distorted versions per parameter at 6 different levels. To address the inter-reader variability, a representative rating is determined as a one-tailed 95% confidence interval of the mean rating. The results of the subjective assessment support the validity of the proposed objective image quality assessment method to model the readers’ perception of image quality. The subjective assessment also provides thresholds for determining the acceptable level of objective quality per parameter. The images for both the subjective and objective quality assessment are based on the HercepTestTM slides scanned by the Philips Ultra Fast Scanners, developed at Philips Digital Pathology Solutions. However, the method is applicable also to other types of slides and scanners.

    2001-09-01

    BACKGROUND. Canalicular injuries and anomalies are relatively common. Despite this, controversy still exists regarding the indications for surgery and best surgical methods. The most favourable intervention would be one that is simple, associated with a high level of subjective and objective outcome, and does not threaten the uninjured or unaffected part of the lacrimal drainage system. This study assesses outcomes of intervention with the Mini Monoka silicone monocanalicular lacrimal stent. METHOD. A single cohort, hospital-based study with retrospective and prospective components. Participants were all identifiable patients at Bristol Eye Hospital in whom the Mini Monoka silicone monocanalicular stent was used for any indication. Retrospective analysis of patient records for all related pre-operative, operative and postoperative data was performed. Prospective analysis of subjective outcome via confidential patient questionnaire and objective outcome via clinical examination was performed. RESULTS. Complete data were obtainable in 13 patients (14 canaliculi) of the identified 22 patients (23 canaliculi). Follow-up was from 12 to 70 months (mean 39 months). A high level of subjective outcome was noted with no patients experiencing significant or disabling symptoms. In terms of objective outcome, 79% achieved canalicular patency. The main complications with this technique were premature stent loss (29%) and stent migration (14%). CONCLUSIONS. The Mini Monoka monocanalicular stent is a safe, effective and simple surgical technique that, unlike bicanalicular procedures, does not threaten the uninjured / unaffected part of the lacrimal drainage system.

    Much research indicates that patients with schizophrenia have impaired olfaction detection ability. However, studies of individuals with psychometrically defined schizotypy reveal mixed results-some document impairments while others do not. In addition to deficits in objective accuracy in olfaction for patients with schizophrenia, there has been an interest in subjective experience of olfaction. Unfortunately, methods of assessing accuracy and subjective hedonic olfactory evaluations in prior studies may not have been sensitive enough to detect group differences in this area. This study employed a measure of olfactory functioning featuring an expanded scoring system to assess both accuracy and subjective evaluations of pleasant and unpleasant experience. Data were collected for patients with schizophrenia, young adults with psychometrically defined schizotypy, psychiatric outpatients, and healthy controls. Results of this study indicate that both the schizophrenia and outpatient psychiatric groups showed similar levels of impaired olfaction ability; however, the schizotypy group was not impaired in olfaction detection. Interestingly, with regard to subjective hedonic evaluation, it was found that patients with schizophrenia did not differ from psychiatric outpatients, whereas individuals with schizotypy tended to rate smells as significantly less pleasant than healthy control participants. This suggests that subjective olfactory assessment is abnormal in some manner in schizotypy. It also suggests that accuracy of olfaction identification may be a characteristic of severe mental illness across severe mental illness diagnoses. The results are potentially important for understanding olfaction deficits across the mental illness spectrum.

    Full Text Available Thermal comfort sensation can be predicted in the most exact way based on Fanger’s predicted mean vote (PMV model. This evaluation method takes all the six influencing factors into consideration: air temperature and humidity, air velocity, mean radiant temperature of surrounding surfaces, clothing insulation, and occupants’ activities. Fanger’s PMV method was developed for temperate climate and European people, with the participation of university students as subjects. Many researchers had investigated its validity in different geographic locations (i. e. climatic conditions, people and under non-laboratory circumstances. The results were summarised by van Hoof which had been published in the scientific references. The articles gave us the idea to elaborate the former measurement results. During the last decades thermal comfort was evaluated by our research team using subjective scientific questionnaires and applying the objective Fanger’s model in several office buildings in Hungary. The relation between the PMV and actual mean vote values were analysed based on these results. Investigations were carried out under steady-state conditions in winter time. We performed objective thermal comfort evaluations based on instrumental measurements using the PMV theory. Parallel to this we assessed the subjective thermal sensation using scientific questionnaires. The mathematical relationship between the actual mean vote and PMV was defined according to the evaluated thermal environment: AMV = PMV + 0.275, (arg. –1.7 ≤ PMV ≤ +0.5.

  11. [Subjective and objective effects of music use during mental effort].

    Liptak, V; Egger, J

    1981-05-15

    The subjective and objective effects of music consumption during intellectual work were assessed by a special questionnaire and the concentration paper-pencil-test (Brickencamp). Three different styles of music (pop-music, classical music and folk-music) were presented in a standardized way. It appeared that pop-music was experienced to be less conscious, less irritable and more pleasant than classical music. Although there was a subjective preference for pop- and folk-music an adequate increase of the concentration-test-scores could not be ascertained. On the contrary a significant discrepancy was found between subjective recorded music-effect and objective measured task-performance. Under the condition of classical music which was least preferred there was a significant greater variance of false responses than under the condition of no music. Nevertheless the total output of the discrimination-task was relatively the highest during classical music. The results are interpreted primarily as an enhanced psycho-physiological activation and a different selective concentration on music-presentation and task-demands. In accordance with empirical findings on psychological and physiological effects of music the results of this study reinforce the statement that also i mental activities music per se does not principally increase or lower the task output.

    Background. Several studies have described but not formally tested discrepancies between subjective and objective measures of sleep. Study Objectives. To test the hypothesis that patients with bipolar disorder display a systematic bias to underestimate sleep duration and overestimate sleep latency. Methods. Actimetry was used to assess sleep latency and duration in 49 euthymic participants (bipolar = 21; healthy controls = 28) for 5–7 days. Participants simultaneously recorded estimated sleep duration and sleep latency on a daily basis via an online sleep diary. Group differences in the discrepancy between subjective and objective parameters were calculated using t-tests and corrected for multiple comparisons. Results. Patients with bipolar disorder significantly underestimated their sleep duration but did not overestimate their sleep latency compared to healthy controls. Conclusions. Studies utilizing diaries or questionnaires alone in patients with bipolar disorders may systematically underestimate sleep duration compared to healthy controls. The additional use of objective assessment methods such as actimetry is advisable. PMID:27891255

  15. Correlation of subjective and objective measures of speech intelligibility

    Bowden, Erica E.; Wang, Lily M.; Palahanska, Milena S.

    2003-10-01

    Currently there are a number of objective evaluation methods used to quantify the speech intelligibility in a built environment, including the Speech Transmission Index (STI), Rapid Speech Transmission Index (RASTI), Articulation Index (AI), and the Percentage Articulation Loss of Consonants (%ALcons). Many of these have been used for years; however, questions remain about their accuracy in predicting the acoustics of a space. Current widely used software programs can quickly evaluate STI, RASTI, and %ALcons from a measured impulse response. This project compares subjective human performance on modified rhyme and phonetically balanced word tests with objective results calculated from impulse response measurements in four different spaces. The results of these tests aid in understanding performance of various methods of speech intelligibility evaluation.

    The pathogenesis of Crohn's disease (CD) is still unknown, but the involvement of the olfactory system in CD appears possible. No study to date has systematically assessed the olfactory function in CD patients. We investigated the olfactory function in CD patients in active (n = 31) and inactive disease (n = 27) and in a control group of age- and sex-matched healthy subjects (n = 35). Subjective olfactory testing was applied using the Sniffin' Sticks test. For olfactory testing, olfactory event-related potentials (OERPs) were obtained with a 4-channel olfactometer using phenyl ethyl alcohol (PEA) and hydrogen sulfide (H(2)S). Carbon dioxide (CO(2)) was employed as control stimulus, and chemosomatosensory event-related potentials (CSSERPs) were registered. Results of the Sniffin' Sticks test revealed significantly different olfactory hedonic judgment with increased olfactory hedonic estimates for pleasant odorants in CD patients in active disease compared with healthy subjects. A statistical trend was found toward lower olfactory thresholds in CD patients. In objective olfactory testing, CD patients showed lower amplitudes of OERPs and CSSERPs. Additionally, OERPs showed significantly shorter N1- and P2 latencies following stimulation of the right nostril with H(2)S in CD patients in inactive disease compared with controls. Our study demonstrates specific abnormalities of olfactory perception in CD patients.

  17. Subjective relevance of objective measures for spatial impression (A)

    DEFF Research Database (Denmark)

    Wang, Lily M.; Gade, Anders Christian

    2000-01-01

    Several objective measures have been proposed to describe the feeling of spatial impression in concert halls, including Lateral Energy Fraction (LF) and Interaural Cross-Correlation Coefficient (IACC). However, previous studies have shown that LF and IACC values did not highly correlate with each...... other at individual seat positions in real halls [J. S. Bradley, J. Acoust. Soc. Am. 96, 3525–3535 (1994)]. To investigate the listener envelopment aspect of spatial impression further, subjective paired-comparison tests have been run using signals which have various values for LF, early IACC (from 5......–80 ms), late IACC (from 80 ms–1 s), and late lateral relative sound level (GLL). Another proposed measure, called Interaural Level Fluctuations (IALF), has also been included, which is based on the rate of change over time of the level difference between the ears. The binaural test signals were...

  18. Population policy forum. Women as subjects, not objects.

    Science.gov (United States)

    Ruether, R R

    1991-01-01

    I very much agree with Marge Berer that feminists must recognize that there needs to be a population policy, worldwide and country by country, that encourages lower birth rates and that it is essential to start talking about population policies that respect and promote women's moral agency. Indeed I think it would be fair to say that the failure to respect and promote women's moral agency is the major reason why government-sponsored population policies have failed in the past. Male population planners habitually think of mass population as objects, rather than subjects, of population policy. This is why they think so readily of "incentives" or even more coercive methods. Birth control is thought of as a "war" to be imposed on the population, not as an integral part of the self-development of the people's own capacity to organize and become decisionmakers. If this is true in relation to the male population, it is even more so in relation to women. Population policy continues the basic male approach to women as bodies under their control, not as self-actualizing subjects. Until population policies take as their starting point women's human development as persons and moral agents in their own right, such policies both will be abusive to women and also will not "work." However, Marge Berer's remarks about oppressive, dehumanizing governments as incapable of promoting any other form of population policy give one pause. If this is the case, then neither national governments nor most international agencies linked to Western hegemonic neocolonialism can be the authentic promoters of feminist population policy. There must be a global effort to build parallel women's health organizations that work on the grassroots level with women, especially poor women, to empower these women themselves to become the leaders in educational and economic development of the women in their communities. Only in and through this larger context can such women both learn how to use and become

  19. Prerequisites for Forming the Institutional Concept of the National Economy Competitiveness under Conditions of Globalization

    Directory of Open Access Journals (Sweden)

    Yaremenko Oleh L.

    2015-03-01

    Full Text Available The article attempts to prove that under conditions of globalization there have developed objective and subjective prerequisites for forming the institutional concept of the national economy. The objective prerequisites are the newest information and communication technologies, post-industrial trends and market transformation of civilization intensified by globalization. Under such conditions instability and volatility of the institutional environment both within national economies and at the international level are observed. The aggravation of the global competition between national economies actualizes the role of such institutional factors as political system, property, public administration, economic organization, culture, etc. The subjective prerequisites are related to the fact that the institutional economic theory is currently one of the leading trends in the modern world and Ukrainian economic thought. Interest in it is explained not only by the fact that it overcomes the limitations of a number of prerequisites for the mainstream, but also because it allows considering the modern economic processes in complex

  20. Web-based evaluation of Parkinson's disease subjects: objective performance capacity measurements and subjective characterization profiles.

    Science.gov (United States)

    Kondraske, George V; Stewart, R Malcolm

    2008-01-01

    Parkinson's Disease (PD) is classified as a progressively degenerative movement disorder, affecting approximately 0.2% of the population and resulting in decreased performance in a wide variety of activities of daily living. Motivated by needs associated with the conduct of multi-center clinical trials, early detection, and the optimization of routine management of individuals with PD, we have developed a three-tiered approach to evaluation of PD and other neurologic diseases/disorders. One tier is characterized as 'web-based evaluation', consisting of objective performance capacity tests and subjective questionnaires that target history and symptom evaluation. Here, we present the initial evaluation of three representative, self-administered, objective, web-based performance capacity tests (simple visual-hand response speed, rapid alternating movement quality, and upper extremity neuromotor channel capacity). Twenty-one subjects (13 with PD, 8 without neurologic disease) were evaluated. Generally good agreement was obtained with lab-based tests executed with an experienced test administrator. We conclude that objective performance capacity testing is a feasible component of a web-based evaluation for PD, providing a sufficient level of fidelity to be useful.

    Clinical epidemiologic studies suggest that once established, voiding dysfunction can become a lifelong condition if not treated correctly early on in life. Biofeedback is one component of a voiding retraining program to help children with voiding dysfunction. Our goal was to compare objective non-invasive urodynamic data obtained during office biofeedback sessions with patient reported voiding symptom scores. Charts of 55 children referred in 2010 for pelvic floor muscle biofeedback therapy for urinary incontinence were retrospectively reviewed. Patients with any anatomic diagnoses were excluded. Forty-seven (86%) females and eight males (14%) with a mean age of 8.2 years made up the cohort. Uroflow curves, voided volumes, and post-void residuals were recorded at each visit and served as objective data. Volumes were normalized as a percentage of expected bladder capacity according to age. The patient reported symptom score and patient reported outcome (improved, no change or worse) served as subjective measures of intervention. The primary referral diagnoses were day and night wetting in 37 (67%) and daytime incontinence in 18 (33%) children. A history of urinary tract infection (UTI) was noted in 32 (64%) patients, and 25% were maintained on antibiotic prophylaxis during the study period. Twenty-nine percent were maintained on anticholinergic medication. Patients attended an average of 2.5 biofeedback sessions. Voided volumes and post void residual volumes were unchanged, 50% of the abnormal uroflow curves normalized over the course of treatment (p biofeedback were rated an improved in 26 (47%), no change in 15 (27%), worse in three (5%) patients, and not rated in 11 patients (21%). Pelvic floor muscle biofeedback is associated with patient-reported improvement in symptoms, reduction in voiding symptom score, and normalization of uroflow curves, but these improvements are not correlated with objective parameters of voided volumes and post-void residual urine

    Interpreters are invariably playing a crucial role in international affairs. Those who regularly read pictorials or watch TV news programs know best why interpreters are always placed between two leaders. That is because interpreters are indispensable if any two VIPs aim to achieve further understanding, to eliminate bilateral distrust or even establish alliance with each other, a fact may partly account for why so many students are swarming into translation schools. Are they able to become interpreters? What are the prerequisites for an interpreter? This article will, taking into operative factors as complete as possible, provide a basic framework under which prerequisites of interpreters are structured.

  6. Merleau-Ponty on embodied subjectivity from the perspective of subject-object circularity

    Directory of Open Access Journals (Sweden)

    Jan Halák

    2016-12-01

    Full Text Available The phenomenological point of view of the body is usually appreciated for having introduced the notion of the ‘lived’ body. We cannot merely analyze and explain the body as one of the elements of the world of objects. We must also describe it, for example, as the center of our perspective on the world, the place where our sensing is ‘localized’, the agens which directly executes our intentions. However, in Husserl, the idea of the body as lived primarily complements his objectivism: the body (Leib is an objective and mental reality, a ‘double unity’, as he writes. In contrast, Merleau-Ponty’s later considerations of the body in Phenomenology of Perception tend to the idea of a circular relationship between the objective and subjective dimensions of the body – between the objective and the lived. One of the means to overcome the idea of the body as a site of the correlation between two opposite and complementary realms is, for Merleau-Ponty, the philosophical interpretation of an early neurological notion of ‘body schema’. Body schema is neither an idea nor a physiological-physical fact, it is rather a practical diagram of our relationships with the world, an action-based norm in reference to which things make sense. In the recently published preparatory notes for his 1953 courses, Merleau-Ponty dedicates much effort to further developing the notion of body schema, and interprets fresh sources that he did not use in Phenomenology of Perception. Notably, he studies various possibilities of how this practical ‘diagram’ can be de-differentiated (pathology or further refined (cognitive and cultural superstructures, symbolic systems, which shows the fundamentally dynamic unity of the body. This paper summarizes the basic elements of Merleau-Ponty’s 1953 renewed philosophical interpretation of the notion of body schema, while contrasting it to the more traditional understanding of the body in phenomenology and in recent

  9. The Constructed Objectivity of Mathematics and the Cognitive Subject

    Science.gov (United States)

    Longo, Giuseppe

    Mathematics is engendered in conjunction with other forms of knowledge, physics in particular. It is a "genealogy of concepts" (Riemann), that stems from our active reconstruction of the world. Mathematics organizes space and time. It stabilizes notions and concepts as no other language, while isolating by them a few intelligible fragments of "reality" at the phenomenal level. Thus an epistemological analysis of mathematics is proposed, as a foundation that departs from and complements the logico-formal approaches: Mathematics is grounded in a formation of sense, of a congnitive and historical nature, which preceeds the explicit formulation of axioms and rules. The genesis of some conceptual invariants will be sketched (numbers, continua, infinity, proofs, etc.). From these, categories as structural invariants (objects) and "invariant preserving maps" (morphisms, functors) are derived, in a reflective equilibrium of theories that parallels our endeavour to gain knowledge of the physical world.

    Internal combustion engines are becoming ever more quiet. However, the more quiet an engine is overall, the more individual disturbing noise shares become conspicuous. These noise shares include diesel engine knocking, injector ticking or rattling and gear drive howling. The degree of annoyance of these disturbing noise shares cannot be adequately described by the noise level. To achieve an efficient evaluation of disturbing noise shares, acoustical characteristic values such as impulsiveness or tonality must be considered. In the research work described in this paper, characteristic values were developed for frequently complained about engine noises. These so called objective parameters rate the disturbing noises on a scale from 1 to 10. The work was carried out on behalf of the Forschungsvereinigung Verbrennungskraftmaschinen e.V. (FVV) at the Institute for Internal Combustion Engines (VKA) of the Aachen University of Technology (RWTH Aachen). (orig.)

  11. Autonomy, subject-relativity, and subjective and objective theories of well-being in bioethics.

    Science.gov (United States)

    Varelius, Jukka

    2003-01-01

    Among the different approaches to questions of biomedical ethics, there is a view that stresses the importance of a patient's right to make her own decisions in evaluative questions concerning her own well-being. This approach, the autonomy-based approach to biomedical ethics, has usually led to the adoption of a subjective theory of well-being on the basis of its commitment to the value of autonomy and to the view that well-being is always relative to a subject. In this article, it is argued that these two commitments need not lead to subjectivism concerning the nature of well-being.

  14. The Effects of Objective and Subjective Socioeconomic Status on Subjective Well-Being among Rural-to-Urban Migrants in China: The Moderating Role of Subjective Social Mobility

    Directory of Open Access Journals (Sweden)

    Silin Huang

    2017-05-01

    Full Text Available Although previous investigations have agreed that Chinese rural-to-urban migrants’ socioeconomic status (SES increases with their migration, the association between SES and subjective well-being is uncertain. To address this research gap, the present study proposed that the association between objective SES and subjective well-being is mediated by subjective SES. This model was tested with a sample of 432 Chinese rural-to-urban migrants. The results indicate a significant association between objective SES and subjective well-being and a partial mediating effect of subjective SES. Furthermore, subjective social mobility, which is one’s expectation about the possibility to move upward in the social hierarchy, was found to moderate both the direct path from objective SES to subjective well-being and the indirect path from subjective SES to subjective well-being. These findings suggest that Chinese rural-to-urban migrants gained in subjective well-being not only because of direct financial achievement but also because of their perceptions and beliefs about their relative social status.

  1. Is an objective refraction optimised using the visual Strehl ratio better than a subjective refraction?

    Hastings, Gareth D; Marsack, Jason D; Nguyen, Lan Chi; Cheng, Han; Applegate, Raymond A

    2017-05-01

    To prospectively examine whether using the visual image quality metric, visual Strehl (VSX), to optimise objective refraction from wavefront error measurements can provide equivalent or better visual performance than subjective refraction and which refraction is preferred in free viewing. Subjective refractions and wavefront aberrations were measured on 40 visually-normal eyes of 20 subjects, through natural and dilated pupils. For each eye a sphere, cylinder, and axis prescription was also objectively determined that optimised visual image quality (VSX) for the measured wavefront error. High contrast (HC) and low contrast (LC) logMAR visual acuity (VA) and short-term monocular distance vision preference were recorded and compared between the VSX-objective and subjective prescriptions both undilated and dilated. For 36 myopic eyes, clinically equivalent (and not statistically different) HC VA was provided with both the objective and subjective refractions (undilated mean ± S.D. was -0.06 ± 0.04 with both refractions; dilated was -0.05 ± 0.04 with the objective, and -0.05 ± 0.05 with the subjective refraction). LC logMAR VA provided by the objective refraction was also clinically equivalent and not statistically different to that provided by the subjective refraction through both natural and dilated pupils for myopic eyes. In free viewing the objective prescription was preferred over the subjective by 72% of myopic eyes when not dilated. For four habitually undercorrected high hyperopic eyes, the VSX-objective refraction was more positive in spherical power and VA poorer than with the subjective refraction. A method of simultaneously optimising sphere, cylinder, and axis from wavefront error measurements, using the visual image quality metric VSX, is described. In myopic subjects, visual performance, as measured by HC and LC VA, with this VSX-objective refraction was found equivalent to that provided by subjective refraction, and was typically preferred

    In this research, the residential environment index system and evaluation model were established by means of subjective and objective methods. The methodology for establishing the evaluation system for residential environment was first analyzed; then the subjective evaluation data-base was established by questionnaire survey; and at the same time, the objective evaluation data-base was constructed by Geographic Information System (GIS); and then the related equation system between subjective and objective system was developed by multiple regression analysis. This research could benefit evaluation of the residential environment quality for various purposes, and also provide important rudimentary data-base for the development and improvement of residential environment for officials. Furthermore, the index system and evaluation model established in this research could construct a strong relation between subjective evaluation and objective data; and thus could provide a comprehensive, efficient and effective methodology for the evaluation of residential environment.

    Full Text Available This paper describes the Old Russian construction involving verbs of perception, thought, and communication. In this construction, a single semantic argument corresponds to two syntactic constituents: a direct object and a finite subordinate clause, the subject of which is coreferential with the direct object of the main clause. The Old Russian construction is seen as an instantiation of a cross-linguistic option in the argument structure of these verbs (above all, of the perception verbs, that is, to take the subject of the subordinate clause as the direct object.

  14. Mood Influences the Concordance of Subjective and Objective Measures of Sleep Duration in Older Adults

    Full Text Available Objective/Background: Sleep plays a central role in maintaining health and cognition. In most epidemiologic studies, sleep is evaluated by self-report questionnaires but several reports suggest that these evaluations might be less accurate than objective measures such as polysomnography or actigraphy. Determinants of the discrepancy between objective and subjective measures remain to be investigated. The aim of this pilot-study was to examine the role of mood states in determining the discrepancy observed between objective and subjective measures of sleep duration in older adults.Patients/Methods: Objective sleep quantity and quality were recorded by actigraphy in a sample of 45 elderly subjects over at least three consecutive nights. Subjective sleep duration and supplementary data, such as mood status and memory, were evaluated using Ecological Momentary Assessment (EMA.Results: A significant discrepancy was observed between EMA and actigraphic measures of sleep duration (p<0.001. The magnitude of this difference was explained by the patient’s mood status (p=0.020. No association was found between the magnitude of this discrepancy and age, sex, sleep quality or memory performance.Conclusion: The discrepancy classically observed between objective and subjective measures of sleep duration can be explained by mood status at the time of awakening. These results have potential implications for epidemiologic and clinical studies examining sleep as a risk factor for morbidity or mortality.

    2017-01-01

    We investigated the prevalence and correlates of discrepancies between self-reported sleep quality (Pittsburgh Sleep Quality Index) and objective sleep efficiency (actigraphy) in older adults with mild cognitive impairment (MCI) and subsyndromal depression. This was a secondary analysis of a clincial trial with 59 adults aged 60 years and older with MCI and subsyndromal depression. We included baseline data on participants' subjective sleep quality, objective sleep efficiency, depressive symptoms, insomnia diagnosis, and cognitive functioning. Pittsburgh Sleep Quality Index subjective sleep quality and actigraphy-measured sleep efficiency were not significantly correlated ( r = -.06; P = .64), with 61% of participants having subjective-objective sleep discrepancies. Correlates of subjective-objective sleep discrepancy included the presence of an insomnia diagnosis and impaired memory, particularly delayed memory. These findings are important because subjective underestimation of symptoms in older adults with memory impairments may result in sleep disturbances going unrecognized in clinical practice; on the other hand, an insomnia disorder may be a possible remediable contribution to subjective overestimation of sleep disturbances.

  16. Objective and subjective stressors and the psychological adjustment of melanoma survivors.

    Hamama-Raz, Y; Solomon, Z; Schachter, J; Azizi, E

    2007-04-01

    This study of 300 melanoma survivors examines the relative contributions of objective illness-related factors (stage of illness at diagnosis, time since diagnosis, and change in physical condition) and of subjective factors (cognitive appraisal) to their psychological adjustment. The findings show that lower appraisal of their situation as a threat, higher appraisal of it as a challenge, and higher appraisal of their subjective ability to cope with it all increased their well-being, while lower threat appraisal and higher appraisal of subjective ability to cope also reduced their distress. These findings, which are consistent with Lazarus and Folkman's stress coping theory, suggest that subjective factors may be more important than objective medical factors in predicting patients' adjustment. With this, more advanced stage at diagnosis contributed to reducing distress, while being married contributed both to higher well-being and reduced distress.

    Previous studies on performance evaluation of single-channel speech separation (SCSS) algorithms mostly focused on automatic speech recognition (ASR) accuracy as their performance measure. Assessing the separated signals by different metrics other than this has the benefit that the results...... methods for audio source separation (PEASS) measures. In our experiments, we apply these measures on the separated signals obtained by two well-known systems in the SCSS challenge to assess the objective and subjective quality of their output signals. Comparing subjective and objective measurements shows...... that PESQ and PEASS quality metrics predict well the subjective quality of separated signals obtained by the separation systems. From the results it is observed that the short-time objective intelligibility (STOI) measure predict the speech intelligibility results....

    Full Text Available The relationship between the objective accuracy of visual-short term memory (VSTM representations and their subjective conscious experience is unknown. We investigated this issue by assessing how the objective and subjective components of VSTM in a delayed cue-target orientation discrimination task are affected by intervening distracters. On each trial, participants were shown a memory cue (a grating, the orientation of which they were asked to hold in memory. On approximately half of the trials, a distractor grating appeared during the maintenance interval; its orientation was either identical to that of the memory cue, or it differed by 10 or 40 degrees. The distractors were masked and presented briefly, so they were only consciously perceived on a subset of trials. At the end of the delay period, a memory test probe was presented, and participants were asked to indicate whether it was tilted to the left or right relative to the memory cue (VSTM accuracy; objective performance. In order to assess subjective metacognition, participants were asked indicate the vividness of their memory for the original memory cue. Finally, participants were asked rate their awareness of the distracter. Results showed that objective VSTM performance was impaired by distractors only when the distractors were very different from the cue, and that this occurred with both subjectively visible and invisible distractors. Subjective metacognition, however, was impaired by distractors of all orientations, but only when these distractors were subjectively invisible. Our results thus indicate that the objective and subjective components of VSTM are to some extent dissociable.

    Full Text Available The dispute about the subjectivity and objectivism is reflected in the field of social sciences and humanities.The very doctrine of  objectivity has become relevant in modern European science project where the problem of truth and error was solved in a new way by differentiating the knowing subject and the known object. Subject of knowledge actually separated himself from the possibility of mixing rational and emotional, and in the object it became possible to differentiate sensible and logical, meaningful and formal. The article focuses on the discussion of modern historical cognition, where in the frame of the dispute about subjectivity and objectivity in the context of historical reconstruction the dilemma is solved: either historical knowledge must be no less objective than natural sciences or subjectivity is quite acceptable in historical science. The author analyzes the problem in the framework of historical and scientific studies on the results of historical reconstruction, identifies the positions of representatives of presentism and antiquarism, and considers the position of F. Brentano about the nature of social identity. The article analyzes the relationship between subject and object of cognition put forward by post-modernists and identifies intellectual conditions and technical means for a more consistent application of a critical approach to scientific thinking.

    Full Text Available The paper is devoted to such topical issue of Criminal Law as Object and Subject of Evasion of Taxes and Other Compulsory Payments. There are analyzed researched crime determination problems, which are connected with subject and object of tax and other compulsory payments evasion. In the course of the research, the author has made the conclusions that the object of the evasion of taxes and other compulsory payments group is the national economic interests. The direct object is the national economic interests in the sphere of state revenues or the national fiscal interests. While analyzing the law and regulations it is concluded that the subject of the evasion of taxes and other compulsory payments is the tax base (income, property, expenses and consumption, taxes, state and local government fees, as well as other payments determined by the State. The author has also concluded that the subject of the evasion of taxes and other compulsory payments does not include increase in the tax principal debt, fine and late charge, which are covered by the financial responsibility. The subject of the evasion of taxes and other compulsory payments may not include also income from illegal activity or proceeds resulting from criminal offences.

Subjects (N=37 being evaluated for OSA were recruited from a sleep clinic. Participants. The sample was balanced by gender (53% male, middle-aged, primarily White, and overweight or obese with a mean BMI of 33.98 (SD=7.35; median BMI=32.30. Over 40% reported subjective sleepiness (Epworth Sleepiness Scale (ESS ≥10 and had OSA (78% with apnea + hypopnea index (AHI ≥5/hr. Measurements. Evaluation included questionnaires to evaluate subjective sleepiness (Epworth Sleepiness Scale (ESS and functional outcomes (Functional Outcomes of Sleep Questionnaire (FOSQ, an activity monitor, and an overnight sleep study to determine OSA severity. Results. Increased subjective sleepiness was significantly associated with lower scores on the FOSQ but not with average number of steps walked per day. A multiple regression analysis showed that higher AHI values were significantly associated with lower average number of steps walked per day after controlling patient's age, sex, and ESS. Conclusion. Subjective sleepiness was associated with perceived difficulty in activity but not with objectively measured activity. However, OSA severity was associated with decreased objective physical activity in aging adults.

    This paper presents a fuzzy multi-criteria decision-making (FMCDM) model by integrating both subjective and objective weights for ranking and evaluating the service quality in hotels. The objective method selects weights of criteria through mathematical calculation, while the subjective method uses judgments of decision makers. In this paper, we use a combination of weights obtained by both approaches in evaluating service quality in hotel industries. A real case study that considered ranking five hotels is illustrated. Examples are shown to indicate capabilities of the proposed method.

    Objective and subjective measures of excessive daytime sleepiness (EDS) are only weakly associated. No study, however, has examined whether these two measures of EDS differ in terms of underlying mechanisms and prognostic value. Pro-inflammatory cytokines, that is, interleukin-6 (IL-6) appear to promote sleepiness/fatigue, while the stress hormone cortisol promotes vigilance. We hypothesized that objective sleepiness is associated with increased levels of IL-6 and decreased levels of cortisol. We studied 58 obstructive sleep apnea (OSA) patients with clinical EDS and/or cardiovascular comorbidities who underwent 8-hour in-lab polysomnography for four consecutive nights. Objective and subjective daytime sleepiness were measured by Multiple Sleep Latency Test (MSLT), Epworth Sleepiness Scale (ESS), and Stanford Sleepiness Scale (SSS), respectively. Twenty-four-hour profiles of IL-6 and cortisol levels were assessed on the fourth day. The agreement between objective and subjective EDS in OSA patients was fair (kappa = 0.22). Objective EDS (lower MSLT) in OSA patients was associated with significantly elevated 24-hour (β = -0.34, p = .01), daytime (β = -0.30, p = .02) and nighttime (β = -0.38, p < .01) IL-6 levels, and significantly decreased daytime (β = 0.35, p = .01) cortisol levels. In contrast, subjective EDS (higher ESS/SSS) was not associated with either elevated IL-6 levels or decreased cortisol levels. Our findings suggest that OSA with objective EDS is the more severe phenotype of the disorder associated with low-grade inflammation, a link to cardiometabolic morbidity and mortality. Compared to subjective EDS, objective EDS is a stronger predictor of OSA severity and may be useful in the clinical management of the disorder.

    The poor relationship between subjective and objective cognitive impairment in bipolar disorder (BD) is well-established. However, beyond simple correlation, this has not been explored further using a methodology that quantifies the degree and direction of the discrepancy. This study aimed to develop such a methodology to explore clinical characteristics predictive of subjective-objective discrepancy in a large BD patient cohort. Data from 109 remitted BD patients and 110 healthy controls were pooled from previous studies, including neuropsychological test scores, self-reported cognitive difficulties, and ratings of mood, stress, socio-occupational capacity, and quality of life. Cognitive symptom 'sensitivity' scores were calculated using a novel methodology, with positive scores reflecting disproportionately more subjective complaints than objective impairment and negative values reflecting disproportionately more objective than subjective impairment ('stoicism'). More subsyndromal depressive and manic symptoms, hospitalizations, BD type II, and being male positively predicted 'sensitivity', while higher verbal IQ predicted more 'stoicism'. 'Sensitive' patients were characterized by greater socio-occupational difficulties, more perceived stress, and lower quality of life. Objective neuropsychological assessment seems especially warranted in patients with (residual) mood symptoms, BD type II, chronic illness, and/or high IQ for correct identification of cognitive deficits before commencement of treatments targeting cognition. © 2016 John Wiley & Sons A/S.

    The objective of this study was to examine the influence of environmental challenges on tic expression by subjective and objective measures. The study group consisted of 41 children aged 6-18 years (M=10.15, SD=2.73) with a primary diagnosis of Tourette syndrome. Subjective measures included the Functional Assessment Interview developed for this study and three standard validated instruments. The objective measure was a video-recording of the patients in five daily-life situations: watching television, doing homework, being alone, receiving attention when ticcing, and talking to a stranger. In addition, the effect of premonitory urges on assessment of tic expression was evaluated. The associations between the subjective and objective measures of tic expression were moderate to low. A significantly higher number of tics were observed in the television situation, and a significantly lower number in the alone situation, compared to the other situations. Higher levels of premonitory urge were associated with greater awareness of objectively measured tic expression. In conclusion, tic expression is significantly influenced by the environment. Subjective measures of tic expression may be misleading. These results have implications for refining the clinical assessment of tics, improving research methodology, and developing new therapeutic strategies.

    The object was to evaluate speech perception improvement through Bluetooth-implemented hearing aids in hearing-impaired adults. Thirty subjects with bilateral symmetric moderate sensorineural hearing loss participated in this study. A Bluetooth-implemented hearing aid was fitted unilaterally in all study subjects. Objective speech recognition score and subjective satisfaction were measured with a Bluetooth-implemented hearing aid to replace the acoustic connection from either a cellular phone or a loudspeaker system. In each system, participants were assigned to 4 conditions: wireless speech signal transmission into hearing aid (wireless mode) in quiet or noisy environment and conventional speech signal transmission using external microphone of hearing aid (conventional mode) in quiet or noisy environment. Also, participants completed questionnaires to investigate subjective satisfaction. Both cellular phone and loudspeaker system situation, participants showed improvements in sentence and word recognition scores with wireless mode compared to conventional mode in both quiet and noise conditions (P Bluetooth-implemented hearing aids helped to improve subjective and objective speech recognition performances in quiet and noisy environments during the use of electronic audio devices.

    Life balance is associated to health, well-being and quality of life and is a target of psychiatric rehabilitation interventions. However, little is known about this life dimension in women living with personality disorders. The purpose of this descriptive-correlational study was to compare and explore relationships between subjective life balance, objective time use, quality of life and perceived stress in women without a mental health disorder (n = 43) and women with a personality disorder (clusters B and C) (n = 30), aged between 18 and 50 years old. The variables were measured with the Life Balance Inventory (subjective life balance), the Occupational Questionnaire (objective time use), the Depression Anxiety Stress Scale (perceived stress) and the Quality of Life Index (satisfaction and importance with life domains). The analyses showed that women with a personality disorder spend significantly less time in work but more time in daily tasks and leisure. Subjective life balance, quality of life and perceived stress were significantly lower in women with a personality disorder (p life balance was explained by quality of life (R(2) = 27.5 %). In women without a mental illness, subjective life balance was explained by quality of life and motherhood (R(2) = 36.1 %). To support the recovery of women with personality disorders and their quality of life, it is important to address objective and subjective time use to enable accomplishment of a variety of meaningful activities.

  17. Fetal subjects and maternal objects: reproductive technology and the new fetal/maternal relation.

    Science.gov (United States)

    Squier, S

    1996-10-01

    This essay examines three tendencies nurtured in the practices of reproductive technology - tendencies with profoundly disturbing implications for us as individuals and as social beings. They are: 1) the increasing subjectification of the fetus (that is, the increasing tendency to posit a fetal subject), 2) the increasing objectification of the gestating woman, leading to her representation as interchangeable object rather than unique subject, and 3) the increasing tendency to conceive of the fetus and the mother as social, medical, and legal antagonists. Considering the construction of fetus, mother, and the fetal/maternal relation in earlier (Western) historical periods, a contemporary work of literature, a government report, and the popular press, I argue that as the fetus is increasingly being understood as a subject, the mother is increasingly being reduced to an antagonist, an obstacle to fetal health, and an object. The essay concludes by offering some tentative conclusions about the general process of fetal subjectification in the United States and Europe.

    Full Text Available Purpose: To evaluate the subjective and objective cyclodeviational changes following different weakening procedures on superior and inferior oblique muscles Design: Comparative case series Materials and Methods: In a prospective institution based study, 16 cases of A pattern horizontal strabismus having superior oblique overaction were randomized to superior oblique weakening procedures: either silicon expander or translational-recession. Similarly, 20 cases of V pattern horizontal strabismus with inferior oblique overaction were randomized for inferior oblique weakening procedures: either 10 mm Fink′s recession or modified Elliot and Nankin′s anteropositioning. Cyclodeviation was assessed subjectively with the synoptophore and objectively using the fundus photograph before surgery and 3 months postoperatively. Change in cyclodeviation was measured by subjective and objective methods. The index of surgical effect (ISE was defined as the net torsional change postoperatively. Results: The difference between the extorsional change induced by the two superior oblique procedures, silicone expander (-6° and translational recession (-11.3°, was statistically significant (P=0.001. Translational recession caused more extorsional change (ISE=296% than silicone expander surgery (ISE=107%. The two inferior oblique weakening procedures, Fink′s recession (+2.5° and modified Elliot and Nankin′s anteropositioning (+4.7° produced equitable amount of intorsional shift with no statistical difference (P=0.93. Objective measurements were significantly more than the subjective measurements. Conclusions: Different weakening procedures on oblique muscles produce different changes in cyclodeviation, which persists even up to 3 months. Subjective cyclodeviation is less than the objective measurements indicating partial compensation by sensorial adaptations.

    Background: The clinical diagnosis of olfactory dysfunction of different etiologies has been standardized by the German Working Group of Olfactology and Gustology, but there is no agreement about the most suitable imaging modality for diagnosing this disorder. Material and methods: A total of 24 patients (13 women, 11 men; mean age 52 years) with different types of olfactory dysfunction (anosmia, hyposmia) were examined by objective and subjective olfactometry and magnetic resonance imaging (MRI) of the olfactory bulb. Results: There was a positive correlation between objective olfactometry and volumetry of the olfactory bulb but no correlation between subjective olfactometry and MRI. Conclusion: MRI allows an evaluation of the olfactory bulb and appears to be superior to other modalities such as computed tomography (CT). Objective olfactometry remains the gold standard for reliable diagnosis of olfactory dysfunction.

    Face perception impairment in schizophrenia has been demonstrated, mostly through experimental studies. How this laboratory-defined behavioral impairment is associated with patients' perceptual experience of various faces in everyday life is however unclear. This question is important because a first-person account of face perception has direct consequences on social functioning of patients. In this study, we adapted and administered a self-reported questionnaire on narrative perceptual experience of faces along with psychophysical assessments of face perception in schizophrenia. The self-reported questionnaire includes six rating items of face-related functioning in everyday life, providing a subjective measure of face perception. The psychophysical assessment determines perceptual threshold for discriminating different facial identities, providing an objective measure of face perception. Compared to controls (n = 25), patients (n = 35) showed significantly lower scores (worse performance) in the subjective assessment and significantly higher thresholds (worse performance) in the objective assessment. The subjective and objective face perception assessments were moderately correlated in controls but not in patients. The subjective face perception assessments were significantly correlated with measurements of a social cognitive ability (Theory of Mind), again in controls but not in patients. These results suggest that in schizophrenia the quality of face-related functioning in everyday life is degraded and the role that basic face discrimination capacity plays in face-related everyday functioning is disrupted.

  1. Subject-object asymmetries in Persian argument ellipsis and the anti-agreement theory

    Full Text Available We investigate the distribution of argument ellipsis in Persian in the context of the recent debate concerning the derivation of null arguments. Using sloppy/quantificational interpretations of elided arguments, we show that Persian exhibits subject-object elliptical asymmetries. We develop various arguments against the Verb-Stranding VP-ellipsis analysis of the subject-object asymmetry. We argue instead that the asymmetry in question is captured by the anti-agreement theory (Saito 2007. Our analysis predicts that the logical subject in Persian should be able to permit argument ellipsis when it is not in the position associated with φ-feature agreement. We show that this prediction is indeed borne out in several syntactic constructions whose inanimate plural subjects do not enter into an agreement relation with any functional head such as T. We also briefly explore one significant consequence of our analysis for the proper treatment of the so-called differential object marker –'râ 'and conclude that this marker is the default morphological case in the technical sense of Marantz (1991.

    Subjective and objective measures of quality of life (QoL) were obtained for adults with autism spectrum disorders (ASDs) living in Andalusia (Spain). Seventy-four families responded to questionnaires about objective QoL indicators such as employment, health, adaptive behaviour and social network, and were asked to act as proxies for subjective QoL measures. Outcome on objective QoL was extremely poor. Social networks were most frequently composed of family members. Community-oriented resources were absent in most cases. For two-thirds of the families, the ability to act as proxies for subjective QoL was seriously limited by the participants' poor social and communicative abilities. The results are indicative of the need for additional support to families of adults with ASD and increased community-based resources. Further conceptualization of indicators and measurement of subjective QoL in individuals with severe disabilities and ASD is also needed in order to include their own perspective in the evaluation of service provision.

    Background: Little is known about physical activity (PA) in the very old, the fastest growing age group in the population. We aimed to examine the convergent validity of subjective and objective measures of PA in adults aged over 85 years. Methods: A total of 484 participants aged 87–89 years recruited to the Newcastle 85+ study completed a purpose-designed physical activity questionnaire (PAQ), which categorised participants as mildly active, moderately active and very active. Out of them, 337 participants wore a triaxial, raw accelerometer on the right wrist over a 5–7-day period to obtain objective measures of rest/activity, PA intensity and PA type. Data from subjective and objective measurement methods were compared. Results: Self-reported PA was significantly associated with objective measures of the daily sedentary time, low-intensity PA and activity type classified as sedentary, activities of daily living and walking. Objective measures of PA were significantly different when low, moderate and high self-reported PA categories were compared (all P Newcastle 85+ PAQ demonstrated convergent validity with objective measures of PA. Our findings suggest that this PAQ can be used in the very old to rank individuals according to their level of total PA. PMID:26018999

    2017-05-01

    Full Text Available An important issue for international businesses and academia is selecting countries in which to expand in order to achieve entrepreneurial sustainability. This study develops a country selection model for sustainable construction businesses using both objective and subjective information. The objective information consists of 14 variables related to country risk and project performance in 32 countries over 25 years. This hybrid model applies subjective weighting from industrial experts to objective information using a fuzzy LinPreRa-based Analytic Hierarchy Process. The hybrid model yields a more accurate country selection compared to a purely objective information-based model in experienced countries. Interestingly, the hybrid model provides some different predictions with only subjective opinions in unexperienced countries, which implies that expert opinion is not always reliable. In addition, feedback from five experts in top international companies is used to validate the model’s completeness, effectiveness, generality, and applicability. The model is expected to aid decision makers in selecting better candidate countries that lead to sustainable business success.

    AIMS Using an established model of smokers cough we measured the antitussive effects of dextromethorphan compared with placebo. METHODS The study was a randomized, double-blind placebo controlled, crossover comparison of 22 mg 0.8 ml−1 dextromethorphan delivered pregastrically with matched placebo. Objective and subjective measurements of cough were recorded. Subjective measures included a daily diary record of cough symptoms and the Leicester quality of life questionnaire. Cough frequency was recorded using a manual cough counter. The objective measure of cough reflex sensitivity was the citric acid, dose–response cough challenge. RESULTS Dextromethorphan was significantly associated with an increase in the concentration of citric acid eliciting an average of two coughs/inhalation (C2) when compared with placebo, 1 h post dose by 0.49 mM (95% CI 0.05, 0.45, geometric mean 3.09) compared with placebo 0.24 mM (geometric mean 1.74) P < 0.05 and at 2 h 0.57 mM (95% CI 0.01, 0.43, geometric mean 3.75) compared with placebo 0.34 mM (geometric mean 2.19) P < 0.05). There was a highly significant improvement in the subjective data when compared with baseline. However, there was no significant difference between placebo and active treatment. No correlation was seen between cough sensitivity to citric acid and recorded cough counts or symptoms. When both subjective and objective data were compared with screening data there was evidence of a marked ‘placebo’ effect. CONCLUSIONS The objective measure of cough sensitivity demonstrates dextromethorphan effectively diminishes the cough reflex sensitivity. However, subjective measures do not support this. Other studies support these findings, which may represent a profound sensitivity of the cough reflex to higher influences. WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Dextromethorphan is widely used as a cough suppressant in over the counter medications. Its efficacy in altering cough reflex sensitivity has been shown in

    2015-01-01

    Background:Many studies examining individual-level correlates in youth utilize self-report rather than objective measures of physical activity (PA). This utilization of self-report may result in associations that are not present when examining objectively measured PA. The present study investigates the relationship between hypothesized correlates of PA with objectively and subjectively measured PA. Methods: Participating children (n = 232, 101 males, mean age = 12.3 years) provided a minimum of four monitored days of PA (via accelerometer) and completed a survey assessing moderate-to-vigorous physical activity (MVPA), sport competence, appearance, enjoyment, and self-efficacy. Height and weight were measured and body mass index (BMI) was calculated. Results: Hierarchical regression models controlling for sex, race, and BMI Z-score showed that only sex and BMI Z-score were significant correlates of objective MVPA while only sex was a significant correlate of objective total PA. However, in a separate model examining the relationship with subjective MVPA, enjoyment of PA and self-efficacy for PA were the only significant correlates of self-reported PA. Conclusion:Measuring MVPA via self-report versus accelerometry produces considerably different results in a sample of young adolescents. Future studies should use caution when selecting outcome measures if the intent is to identify modifiable correlates of MVPA in youth.

    Full Text Available This paper assesses the Website of a chemical company, Deza, relative to strategy and Website quality. In an attempt to obtain both an objective and subjective measure of the quality of the Deza website, two assessment methods have been used. Firstly, a subjective assessment was conducted based on the WebQual survey instrument proposed by Barnes and Vidgen (2000. Secondly, a more objective assessment was conducted via an “informational content analysis”, based on the work of Carlson et. al. (2001. Analysis of the results of the WebQual survey suggest that overall, the Deza Website is perceived by the user as being of a higher quality than the Koppers Website, but a lower quality then the Nalon Website. The Information content analysis also ranks the Deza website as being superior to Koppers and inferior to Nalon.

  9. Hamming Distance Method with Subjective and Objective Weights for Personnel Selection

    2014-01-01

    Full Text Available Multicriteria decision making (MCDM is one of the methods that popularly has been used in solving personnel selection problem. Alternatives, criteria, and weights are some of the fundamental aspects in MCDM that need to be defined clearly in order to achieve a good result. Apart from these aspects, fuzzy data has to take into consideration that it may arise from unobtainable and incomplete information. In this paper, we propose a new approach for personnel selection problem. The proposed approach is based on Hamming distance method with subjective and objective weights (HDMSOW’s. In case of vagueness situation, fuzzy set theory is then incorporated onto the HDMSOW’s. To determine the objective weight for each attribute, the fuzzy Shannon’s entropy is considered. While for the subjective weight, it is aggregated into a comparable scale. A numerical example is presented to illustrate the HDMSOW’s.

    Several studies discuss the influence of complexity on the visual short term memory; some have demonstrated that short-term memory is surprisingly stable regardless of content (e.g. Luck & Vogel, 1997) where others have shown that memory can be influenced by the complexity of stimulus (e.g. Alvarez...... characters. On the contrary expertise or word frequency may reflect what could be termed subjective complexity, as this relate directly to the individual mental categories established. This study will be able to uncover more details on how we should define complexity of objects to be encoded into short-term....... & Cavanagh, 2004). But the term complexity is often not clearly defined. Sørensen (2008; see also Dall, Katsumi, & Sørensen, 2016) suggested that complexity can be related to two different types; objective and subjective complexity. This distinction is supported by a number of studies on the influence...

  11. The moderating role of objective and subjective numeracy in attribute framing.

    Science.gov (United States)

    Gamliel, Eyal; Kreiner, Hamutal; Garcia-Retamero, Rocio

    2016-04-01

    Previous research has found that objective numeracy moderates framing effects: People who are less numerate were found to be more susceptible to goal-framing and attribute-framing effects than people who are highly numerate. This study examined the possibility that subjective numeracy likewise moderates attribute framing in contexts where participants are presented with percentages of success or failure. The results show that compared with highly numerate participants, less numerate participants were more susceptible to the effect of attribute framing. Interestingly, this moderating effect was revealed only when using objective numeracy measures, and not when subjective numeracy measures were used. Future research is suggested to replicate these findings, to establish the generalizability of numeracy as a moderator of other cognitive biases, and to examine several possible theoretical explanations for the differential moderation of attribute-framing bias.

  12. Objective measurement of daytime napping, cognitive dysfunction and subjective sleepiness in Parkinson's disease.

    Samuel J Bolitho

    Full Text Available INTRODUCTION: Sleep-wake disturbances and concomitant cognitive dysfunction in Parkinson's disease (PD contribute significantly to morbidity in patients and their carers. Subjectively reported daytime sleep disturbance is observed in over half of all patients with PD and has been linked to executive cognitive dysfunction. The current study used daytime actigraphy, a novel objective measure of napping and related this to neuropsychological performance in a sample of PD patients and healthy, age and gender-matched controls. Furthermore this study aimed to identify patients with PD who may benefit from pharmacologic and behavioural intervention to improve these symptoms. METHODS: Eighty-five PD patients and 21 healthy, age-matched controls completed 14 days of wrist actigraphy within two weeks of neuropsychological testing. Objective napping measures were derived from actigraphy using a standardised protocol and subjective daytime sleepiness was recorded by the previously validated Epworth Sleepiness Scale. RESULTS: Patients with PD had a 225% increase in the mean nap time per day (minutes as recorded by actigraphy compared to age matched controls (39.2 ± 35.2 vs. 11.5 ± 11.0 minutes respectively, p < 0.001. Significantly, differences in napping duration between patients, as recorded by actigraphy were not distinguished by their ratings on the subjective measurement of excessive daytime sleepiness. Finally, those patients with excessive daytime napping showed greater cognitive deficits in the domains of attention, semantic verbal fluency and processing speed. CONCLUSION: This study confirms increased levels of napping in PD, a finding that is concordant with subjective reports. However, subjective self-report measures of excessive daytime sleepiness do not robustly identify excessive napping in PD. Fronto-subcortical cognitive dysfunction was observed in those patients who napped excessively. Furthermore, this study suggests that daytime

    The aim of this research is to develop and introduce into phoniatric diagnostic procedures the complex methodology of vocal function assessment, on the basis of comparison of subjective and objective voice estimation. The set of complex voice evaluation ought to include perceptual examination of the voice quality with quantitative GRBAS scale as a subjective method, vocal folds vibrations in videostroboscopy as a quasi-objective method and acoustic voice estimation in Multi Dimensional Voice Program (MDVP) as an objective method. The basic assumption of this report is to prove correlation existence for vocal folds vibration quality in videostroboscopy, parameters describing acoustic wave generating by vibration system in larynx (MDVP) and perceptual subjective voice assessment (GRBAS scale) in organic and functional voice disorders. Research was conducted on 100 subjects (65 with organic and 35 with functional voice disorder), aged 7-74 years randomly chosen from population of patients treated at the Department of Phoniatrics and Audiology, Karol Marcinkowski University School of Medical Sciences in Poznań in 1996-2001 and 60 subjects as a control group without any voice disorders according to phoniatric examination. The research methodology include perceptual voice evaluation based on Japanese (Hirano) GRBAS scale adapted to Polish language, in scale 0 to 3 as well as the vibrations of vocal folds in videostroboscopy with attempt at quantification (scale 1 to 3) of selected measure and for acoustic analysis of Multi Dimensional Voice Program (MDVP) for 17 estimated parameters. Due to results and statistic analysis the own, new scale of dysphonia severity was introduced.

    Quality of life (QoL) is considered an important outcome in health research. It can be rated by the patient, or by an external assessor. We wished to identify the predictors of any discrepancies between these two approaches in people with schizophrenia. Patients with DSM schizophrenia and related disorders (N = 80) completed both patient-rated (Lancashire Quality of Life Profile; LQOLP) and assessor-rated (Heinrich's Quality of Life Scale; QLS) measures of QoL. Patient-rated (LQOLP) and assessor-rated (QLS) measures showed a modest correlation (r = 0.38). In a regression analysis, independent predictors of subjectively-rated QoL being higher than objectively-assessed QoL in the same patient, were low insight score (BIS), negative symptoms (PANSS), absence of depression (CDSS), and less positive attitude toward prescribed treatment (DAI). In people with schizophrenia, scores on objectively- and subjectively-rated measures of quality of life can differ markedly. When comparing subjective to objective assessments, patients with depressive symptoms will value their QoL lower, and those with low insight will value their QoL higher. This has important implications for the utility and interpretation of QoL measures in schizophrenia.

    Several recent studies showed the optimal contrast enhancement with a low-concentration and iso-osmolar contrast media in both adult and pediatric patients. However, low contrast media concentrations are not routinely used due to concerns of suboptimal enhancement of cardiac structures and small vessels. To evaluate the feasibility of using iso-osmolar contrast media containing a low iodine dose for CT cardiac angiography at 80 kilovolts (kVp) in neonates and infants. The iodixanol 270 group consisted of 79 CT scans and the iopromide 370 group of 62 CT scans in patients ≤1 year old. Objective measurement of the contrast enhancement was analyzed and contrast-to-noise ratios of the ascending aorta and left ventricle were calculated. Regarding subjective measurement, a four-point scale system was devised to evaluate degrees of contrast enhancement, image noise, motion artifact and overall image quality of each image set. Reader performance for correctly differentiating iodixanol 270 and iopromide 370 by visual assessment was evaluated. Group objective and subjective measurements were nonsignificantly different. Overall sensitivity, specificity and diagnostic accuracy for correctly differentiating iodixanol 270 and iopromide 370 by visual assessment were 42.8%, 59%, and 50%, respectively. The application of iodixanol 270 achieved optimal enhancement for performing pediatric cardiac CT angiography at 80 kVp in neonates and infants. Objective measurements of contrast enhancement and subjective image quality assessments were not statistically different in the iodixanol 270 and iopromide 370 groups. (orig.)

We assessed ICs objective burden (Resource Utilization in Dementia measuring informal care time (ICT and ICs subjective burden (Zarit Burden Inventory (ZBI. Results. ICs (N=99 were spouses (70%, mean age 52 years, assisting disabled patients with a mean EDSS (Expanded Disability Status Scale of 5.5, with executive dysfunction (mean DEX (Dysexecutive questionnaire of 25 and a duration of MS ranging from 1 to 44 years. Objective burden was high (mean ICT = 6.5 hours/day, mostly consisting of supervision time. Subjective burden was moderate (mean ZBI = 27.3. Multivariate analyses showed that both burdens were positively correlated with higher levels of EDSS and DEX, whereas coresidency and IC’s female gender correlated with objective burden only and IC’s poor mental health status with subjective burden only. When considering MS aggressiveness, it appeared that both burdens were not correlated with a higher duration of MS but rather increased for patients with severe and early dysexecutive function and for patients classified as fast progressors according to the Multiple Sclerosis Severity Score. Conclusion. Evaluation of MS disability course and IC’s personal situation is crucial to understand the burden process and to implement adequate interventions in MS.

    Despite the relatively high prevalence of the polycystic ovary syndrome (PCOS) affecting up to 15% of all women of reproductive age, only little is known about vocal changes related to this endocrinologic disorder that is characterized by biochemical or clinical hyperandrogenism, impaired cycles, and/or polycystic ovaries. The aim of our study was to describe objective and subjective vocal changes in women with a diagnosed PCOS compared with a control group. Our study group comprised 34 women-24 cases with confirmed PCOS and 10 controls in whom PCOS was excluded. A complete endocrinologic laboratory status was obtained by all participants; study procedures included a videolaryngostroboscopy, voice recording, and completion of the German version of the Voice Handicap Index. A trend toward lower mean fundamental frequency was detectable, but this failed statistical significance. No differences were found in the objective and subjective voice parameters. Elevated serum levels of androgens, as found in women with PCOS, were shown not to have an impact on the subjective and objective voice parameters. Copyright © 2013 The Voice Foundation.

    Full Text Available Problem based learning curriculum is widely recognized as a progressive, learner-centered, active learning approach and is currently used in the entire medical curriculum in over 10% of medical schools worldwide. But, is there real evidence that PBL is more effective than traditional approaches? In this report, outcomes of a PBL tutorial in 55 second year MBBS students have been evaluated by the facilitators (subjective evaluation and by asking the students a set of questions based on the intended outcome of the PBL ( objective evaluation soon after the completion of PBL tutorial. In the subjective assessment by the facilitators, all the students scored over 80% marks. In the objective assessment, out of 55 students, only three students scored over 50% marks. Perusal of answers to individual questions revealed appalling lack of knowledge of the subject. To conclude, before introduction of PBL-based curriculum in medical schools, usefulness of PBLs in preclinical medical education needs to be thoroughly investigated by objective evaluation of intended outcomes.

  20. Automaticity and primacy of auditory streaming: Concurrent subjective and objective measures.

    Billig, Alexander J; Carlyon, Robert P

    2016-03-01

    Two experiments used subjective and objective measures to study the automaticity and primacy of auditory streaming. Listeners heard sequences of "ABA-" triplets, where "A" and "B" were tones of different frequencies and "-" was a silent gap. Segregation was more frequently reported, and rhythmically deviant triplets less well detected, for a greater between-tone frequency separation and later in the sequence. In Experiment 1, performing a competing auditory task for the first part of the sequence led to a reduction in subsequent streaming compared to when the tones were attended throughout. This is consistent with focused attention promoting streaming, and/or with attention switches resetting it. However, the proportion of segregated reports increased more rapidly following a switch than at the start of a sequence, indicating that some streaming occurred automatically. Modeling ruled out a simple "covert attention" account of this finding. Experiment 2 required listeners to perform subjective and objective tasks concurrently. It revealed superior performance during integrated compared to segregated reports, beyond that explained by the codependence of the two measures on stimulus parameters. We argue that listeners have limited access to low-level stimulus representations once perceptual organization has occurred, and that subjective and objective streaming measures partly index the same processes.

    Full Text Available Advances in wearable technology allow for the objective assessment of motor performance in both in-home and in-clinic environments and were used to explore motor impairments in Parkinson's disease (PD. The aims of this study were to: 1 assess differences between in-clinic and in-home gait speed, and sit-to-stand and stand-to-sit duration in PD patients (in comparison with healthy controls; and 2 determine the objective physical activity measures, including gait, postural balance, instrumented Timed-up-and-go (iTUG, and in-home spontaneous physical activity (SPA, with the highest correlation with subjective/semi-objective measures, including health survey, fall history (fallers vs. non-fallers, fear of falling, pain, Unified Parkinson's Disease Rating Scale, and PD stage (Hoehn and Yahr. Objective assessments of motor performance were made by measuring physical activities in the same sample of PD patients (n = 15, Age: 71.2±6.3 years and age-matched healthy controls (n = 35, Age: 71.9±3.8 years. The association between in-clinic and in-home parameters, and between objective parameters and subjective/semi-objective evaluations in the PD group was assessed using linear regression-analysis of variance models and reported as Pearson correlations (R. Both in-home SPA and in-clinic assessments demonstrated strong discriminatory power in detecting impaired motor function in PD. However, mean effect size (0.94±0.37 for in-home measures was smaller compared to in-clinic assessments (1.30±0.34 for parameters that were significantly different between PD and healthy groups. No significant correlation was observed between identical in-clinic and in-home parameters in the PD group (R = 0.10-0.25; p>0.40, while the healthy showed stronger correlation in gait speed, sit-to-stand duration, and stand-to-sit duration (R = 0.36-0.56; p<0.03. This suggests a better correlation between supervised and unsupervised motor function assessments in healthy controls

    In the context of task sharing between a robot companion and its human partners, the notions of safe and compliant hardware are not enough. It is necessary to guarantee ergonomic robot motions. Therefore, we have developed Human Aware Manipulation Planner (Sisbot et al., 2010), a motion planner specifically designed for human-robot object transfer by explicitly taking into account the legibility, the safety and the physical comfort of robot motions. The main objective of this research was to define precise subjective metrics to assess our planner when a human interacts with a robot in an object hand-over task. A second objective was to obtain quantitative data to evaluate the effect of this interaction. Given the short duration, the "relative ease" of the object hand-over task and its qualitative component, classical behavioral measures based on accuracy or reaction time were unsuitable to compare our gestures. In this perspective, we selected three measurements based on the galvanic skin conductance response, the deltoid muscle activity and the ocular activity. To test our assumptions and validate our planner, an experimental set-up involving Jido, a mobile manipulator robot, and a seated human was proposed. For the purpose of the experiment, we have defined three motions that combine different levels of legibility, safety and physical comfort values. After each robot gesture the participants were asked to rate them on a three dimensional subjective scale. It has appeared that the subjective data were in favor of our reference motion. Eventually the three motions elicited different physiological and ocular responses that could be used to partially discriminate them. Copyright © 2011 Elsevier Ltd and the Ergonomics Society.

    participant—whereas control deficit subjects’ temporal lobe damage was more severe in the left hemisphere and typically unilateral. Therefore, these results suggest our three tasks were sufficient for differentiating anomic subjects with either a control deficit or a storage deficit. Also, considering the worse performance by control deficit subjects for the verbal version of the Camels and Cactus test, the results are consistent with previous arguments that the left temporal lobe is more specialized for verbal knowledge whereas the right temporal lobe is more specialized for visual knowledge (Gainotti, 2014. We also found, however, that this difference on the word version was isolated to living objects only. For manmade objects, control deficit subjects’ answers were similar to normal elderly controls. Therefore, the results suggest that animacy effects may be less related to a loss of visual semantic knowledge, as predicted by the sensory-functional hypothesis, because control deficit subjects performed well on the visual Camels and Cactus Test. Instead, animacy effects may be more related to the location of atrophy within the left temporal lobe.

    Medical Image Quality Assessment (IQA) plays an important role in assisting and evaluating the development of any new hardware, imaging sequences, pre-processing or post-processing algorithms. We have performed a quantitative analysis of the correlation between subjective and objective Full Reference - IQA (FR-IQA) on Magnetic Resonance (MR) images of the human brain, spine, knee and abdomen. We have created a MR image database that consists of 25 original reference images and 750 distorted images. The reference images were distorted with six types of distortions: Rician Noise, Gaussian White Noise, Gaussian Blur, DCT compression, JPEG compression and JPEG2000 compression, at various levels of distortion. Twenty eight subjects were chosen to evaluate the images resulting in a total of 21,700 human evaluations. The raw scores were then converted to Difference Mean Opinion Score (DMOS). Thirteen objective FR-IQA metrics were used to determine the validity of the subjective DMOS. The results indicate a high correlation between the subjective and objective assessment of the MR images. The Noise Quality Measurement (NQM) has the highest correlation with DMOS, where the mean Pearson Linear Correlation Coefficient (PLCC) and Spearman Rank Order Correlation Coefficient (SROCC) are 0.936 and 0.938 respectively. The Universal Quality Index (UQI) has the lowest correlation with DMOS, where the mean PLCC and SROCC are 0.807 and 0.815 respectively. Student's T-test was used to find the difference in performance of FR-IQA across different types of distortion. The superior IQAs tested statistically are UQI for Rician noise images, Visual Information Fidelity (VIF) for Gaussian blur images, NQM for both DCT and JPEG compressed images, Peak Signal-to-Noise Ratio (PSNR) for JPEG2000 compressed images.

    The goal of this study was to determine the accuracy of autorefraction measurements in patients after INTRACOR intrastromal femtosecond laser treatment of presbyopia by comparing the agreement between the subjective and objective refraction. In this study the data of 19 patients with a mean age of 56.5±6.0 years following INTRACOR treatment were analyzed pre-operatively and 12 months postoperatively. Measurements of the subjective refraction and the results of the autorefractor Nidek-660A in miosis were compared. INTRACOR is a refractive intrastromal femtosecond laser treatment to correct presbyopia. During the procedure a series of five concentric rings in the central stroma are cut which cause a change in the curvature of the cornea. The differences in sphere and spherical equivalent between subjective refraction and autorefraction were not significant (t-test p>0.05 and Wilcoxon test p>0.05). Comparing the cylinder of the two measurements a significant difference (t-test prefraction and autorefraction a correlation (within ±0.5 D) of 89% in the sphere, 100% in cylinder and 68% in the spherical equivalent was detected. With one exception the differences in sphere, cylinder and the spherical equivalent were within ±1.25 D. In several patients the performance of the autorefraction with the Nidek-660A was somewhat complicated and the measures had to be repeated frequently. The agreement between subjective refraction and objective measurements of the Nidek-660A of patients following INTRACOR-treatment was good. However there was a significant difference in the cylinder values. Therefore thorough comparison of measurements obtained with the autorefractor and the subjective refraction is recommended.

    Full Text Available The article is devoted to one of the most actual and complex problems of the modern Russian society - the conflict of the doctor and the patient. It analyzes the causes of the objective and subjective factors of the conflict in the modernization of health and medical care. Among the objective reasons are the imperfections of the regulatory framework in the field of health care, poor quality education of future health workers, expanding the range of paid medical services, the destructive activities of the media, “warming up” conflicting confrontation. In it the objective reasons and subjective factors of occurrence of this conflict in the conditions of modernization of public health services and population health services are analyzed. Among the objective reasons the special attention is given to imperfection of standard base in the field of public health services, to poor quality of formation at the future medical workers, to expansion of a spectrum of paid medical services, destructive activity of the mass-media, “warming up” disputed opposition. The author connects subjective factors of the conflict with specificity of the medical profession and the characteristics of its implementation in recent years. First of all, they are - the deformation of professional consciousness of doctors, low motivation for their work and a lack of interest physician in treating the patient. The problem of the conflict is exacerbated by the imbalance of the system management of personnel potential of the industry, weakening the control of the medical organizations. “Medical errors” and poor development of evidence-based medicine in recent years have caused a great resonance in society. In conclusion the author proposes preventive measures to reduce social conflict of “doctor and patient” and the scientific development of social harmonization in the relationship.

    Socioeconomic position (SEP) is inversely associated with many health outcomes, yielding a socioeconomic gradient in health. In adults, low SEP is associated with short sleep duration, poorer sleep quality, and difficulty initiating and maintaining sleep. Relatively little is known about this relation in youth. The aim of the present study was to examine whether socioeconomic gradients exist for various sleep indices among a healthy sample of children and adolescents. Participants took part in the larger Healthy Heart Project and included 239 youth (69.6% Caucasian; 45.6% female), aged 8-17 years (M = 12.6, SD = 1.9). Parental income and education were used to measure objective SEP. The Subjective Social Status Scale-Youth Version was used to measure subjective SEP. Sleep duration, sleep quality, daytime sleepiness, and sleep disturbances were assessed through self- and parent-report. In children, objective SEP was related with sleep duration (β = .35, p parent-reported sleep duration (β = .23, p parent-reported sleep duration (β = -.18, p parental SEP was related with sleep complaints (e.g., sleep disturbances), and subjective SEP was related with sleep quality and daytime sleepiness. Findings suggest sleep may be one pathway underlying the socioeconomic gradient in health. Future research should aim to elucidate how distinct sleep constructs may explain how socioeconomic status "gets under the skin" to affect health.

    The objective was to study the involuntary capture of attention by spoken words varying in intonation and valence. In studies of verbal alarms, the propensity of alarms to capture attention has been primarily assessed with the use of subjective ratings of their perceived urgency. Past studies suggest that such ratings vary with the alarms' spoken urgency and content. We measured attention capture by spoken words varying in valence (negative vs. neutral) and intonation (urgently vs. nonurgently spoken) through subjective ratings and behavioral measures. The key behavioral measure was the response latency to visual stimuli in the presence of spoken words breaking away from the periodical repetition of a tone. The results showed that all words captured attention relative to a baseline standard tone but that this effect was partly counteracted by a relative speeding of responses for urgently compared with nonurgently spoken words. Word valence did not affect behavioral performance. Rating data showed that both intonation and valence increased significantly perceived urgency and attention grabbing without any interaction. The data suggest a congruency between subjective ratings and behavioral performance with respect to spoken intonation but not valence. This study demonstrates the usefulness and feasibility of objective measures of attention capture to help design efficient alarm systems.

    Full Text Available In the article it is pointed out that European and worldwide integration processes, the informatization and the competitive character of all the spheres of social life require the overcoming of the tendency of “catching up” that is characteristic of Ukraine — in favour of leaving behind the transformation of the educational sphere, especially the pedagogical one.

    Full Text Available Abstract Rationale Several lines of evidence suggest that cocaine expectancy and craving are two related phenomena. The present study assessed this potential link by contrasting reactions to varying degrees of the drug's perceived availability. Method Non-treatment seeking individuals with cocaine dependence were administered an intravenous bolus of cocaine (0.2 mg/kg under 100% ('unblinded'; N = 33 and 33% ('blinded'; N = 12 probability conditions for the delivery of drug. Subjective ratings of craving, high, rush and low along with heart rate and blood pressure measurements were collected at baseline and every minute for 20 minutes following the infusions. Results Compared to the 'blinded' subjects, their 'unblinded' counterparts had similar craving scores on a multidimensional assessment several hours before the infusion, but reported higher craving levels on a more proximal evaluation, immediately prior to the receipt of cocaine. Furthermore, the 'unblinded' subjects displayed a more rapid onset of high and rush cocaine responses along with significantly higher cocaine-induced heart rate elevations. Conclusion These results support the hypothesis that cocaine expectancy modulates subjective and objective responses to the drug. Provided the important public health policy implications of heavy cocaine use, health policy makers and clinicians alike may favor cocaine craving assessments performed in the settings with access to the drug rather than in more neutral environments as a more meaningful marker of disease staging and assignment to the proper level of care.

    Full Text Available Computed tomography perfusion (CTP imaging in acute ischemic stroke (AIS suffers from measurement errors due to image noise. The purpose of this study was to investigate if iterative reconstruction (IR algorithms can be used to improve the diagnostic value of standard-dose CTP in AIS.Twenty-three patients with AIS underwent CTP with standardized protocol and dose. Raw data were reconstructed with filtered back projection (FBP and IR with intensity levels 3, 4, 5. Image quality was objectively (quantitative perfusion values, signal-to-noise ratio (SNR, contrast-to-noise ratio (CNR and subjectively (overall image quality assessed. Ischemic core and perfusion mismatch were visually rated. Discriminative power for tissue outcome prediction was determined by the area under the receiver operating characteristic curve (AUC resulting from the overlap between follow-up infarct lesions and stepwise thresholded CTP maps.With increasing levels of IR, objective image quality (SNR and CNR in white matter and gray matter, elimination of error voxels and subjective image quality improved. Using IR, mean transit time (MTT was higher in ischemic lesions, while there was no significant change of cerebral blood volume (CBV and cerebral blood flow (CBF. Visual assessments of perfusion mismatch changed in 4 patients, while the ischemic core remained constant in all cases. Discriminative power for infarct prediction as represented by AUC was not significantly changed in CBV, but increased in CBF and MTT (mean (95% CI: 0.72 (0.67-0.76 vs. 0.74 (0.70-0.78 and 0.65 (0.62-0.67 vs 0.67 (0.64-0.70.In acute stroke patients, IR improves objective and subjective image quality when applied to standard-dose CTP. This adds to the overall confidence of CTP in acute stroke triage.

    This study aims to comprehensively assess the association of subjective and objective oral health status and oral health behaviors with happiness, under consideration of demographic, socioeconomic, and general health-related factors. This study also aims to test whether subjective oral health outcomes are better predictors of happiness compared with objective oral health outcomes. The data were collected from 479 community-dwelling elders aged 65 years or over selected by a cluster sampling method. A questionnaire and an oral examination were implemented. A multiple regression method was conducted to assess associations with happiness index (HI). The mean age of the elders was 74.6 years. Mean (standard deviation, SD) HI, EuroQol-visual analog scale (EQ-VAS) and 14-item oral health impact profile (OHIP-14) index were 5.7 (SD 2.3), 59.8 (SD 21.1), and 16.3 (SD 13.1). In the final model, a significant association with HI of the OHIP-14 index (P = 0.091) among all the participants and significant associations of oral symptoms (P = 0.038), wearing a removable denture (P = 0.039), and of the oral health behavior of daily toothbrushing (P = 0.007) among poorer oral health QoL group were confirmed under consideration of other related factors. While correlations of HI to subjective measures of health, EQ-VAS and OHIP-14 score were moderate to weak, those to objective measures of health were only weak or insignificant. Oral impacts which might persistently affect one's daily life need to be considered in designing and delivering public services aimed to promote people's happiness. With oral health impacts and behaviors accounting for 10% of happiness among elders, public and community services for the elderly that support oral health and daily toothbrushing for the dentate are critical for the well-being of our elders. © 2013 John Wiley & Sons A/S.

    Full Text Available Sleep quality decreases with aging and thus sleep complaints are prevalent in older adults, particularly for those with cognitive impairment and dementia. For older adults, emerging evidence suggests poor sleep quality increases risk of developing cognitive impairment and dementia. Given the aging population – and the impending economic burden associated with increasing numbers of dementia patients – there is pressing need to improve sleep quality among older adults. As such, research efforts have increased focus on investigating the association between age-related sleep changes and cognitive decline in older adults. Sleep quality is a complex construct to evaluate empirically, and yet the Pittsburg Sleep Quality Index (PSQI is commonly used in studies as their only measure of sleep quality. Furthermore, the PSQI may not be the best sleep quality measure for older adults, due to its reliance on the cognitive capacity to reflect on the past month. Further study is needed to determine the PSQI’s validity among older adults. Thus, the current study examined sleep quality for 78 community dwelling adults 55+ to determine the PSQI’s predictive validity for objective sleep quality (as measured by actigraphy. We compared two subjective measures of sleep quality – the PSQI and Consensus Sleep Diary (CSD – with actigraphy (MotionWatch 8; camntech. Our results suggest perceived sleep quality is quite different from objective reality, at least for adults 55+. Importantly, we show this difference is unrelated to age, gender, education, or cognitive status (assessed using standard screens. Previous studies have shown the PSQI to be a valuable tool for assessing subjective sleep quality; however, our findings indicate for older adults the PSQI should not be used as a substitute for actigraphy, or vice versa. Hence, we conclude best practice is to include both subjective and objective measures when examining sleep quality in older adults (i.e., the

    Manuela M Marin

    Full Text Available Subjective complexity has been found to be related to hedonic measures of preference, pleasantness and beauty, but there is no consensus about the nature of this relationship in the visual and musical domains. Moreover, the affective content of stimuli has been largely neglected so far in the study of complexity but is crucial in many everyday contexts and in aesthetic experiences. We thus propose a cross-domain approach that acknowledges the multidimensional nature of complexity and that uses a wide range of objective complexity measures combined with subjective ratings. In four experiments, we employed pictures of affective environmental scenes, representational paintings, and Romantic solo and chamber music excerpts. Stimuli were pre-selected to vary in emotional content (pleasantness and arousal and complexity (low versus high number of elements. For each set of stimuli, in a between-subjects design, ratings of familiarity, complexity, pleasantness and arousal were obtained for a presentation time of 25 s from 152 participants. In line with Berlyne's collative-motivation model, statistical analyses controlling for familiarity revealed a positive relationship between subjective complexity and arousal, and the highest correlations were observed for musical stimuli. Evidence for a mediating role of arousal in the complexity-pleasantness relationship was demonstrated in all experiments, but was only significant for females with regard to music. The direction and strength of the linear relationship between complexity and pleasantness depended on the stimulus type and gender. For environmental scenes, the root mean square contrast measures and measures of compressed file size correlated best with subjective complexity, whereas only edge detection based on phase congruency yielded equivalent results for representational paintings. Measures of compressed file size and event density also showed positive correlations with complexity and arousal in

    2014-07-01

    Full Text Available This paper studies in detail how different evaluation methods perform when it comes to describing the performance of haptically controlled mobile manipulators. Particularly, we investigate how well subjective metrics perform compared to objective metrics. To find the best metrics to describe the performance of a control scheme is challenging when human operators are involved; how the user perceives the performance of the controller does not necessarily correspond to the directly measurable metrics normally used in controller evaluation. It is therefore important to study whether there is any correspondence between how the user perceives the performance of a controller, and how it performs in terms of directly measurable metrics such as the time used to perform a task, number of errors, accuracy, and so on. To perform these tests we choose a system that consists of a mobile manipulator that is controlled by an operator through a haptic device. This is a good system for studying different performance metrics as the performance can be determined by subjective metrics based on feedback from the users, and also as objective and directly measurable metrics. The system consists of a robotic arm which provides for interaction and manipulation, which is mounted on a mobile base which extends the workspace of the arm. The operator thus needs to perform both interaction and locomotion using a single haptic device. While the position of the on-board camera is determined by the base motion, the principal control objective is the motion of the manipulator arm. This calls for intelligent control allocation between the base and the manipulator arm in order to obtain intuitive control of both the camera and the arm. We implement three different approaches to the control allocation problem, i.e., whether the vehicle or manipulator arm actuation is applied to generate the desired motion. The performance of the different control schemes is evaluated, and our

    Full Text Available Background Sleep disorder is one of the most common non-motor symptoms in Parkinson's disease (PD patients. At present, there are subjective and objective tools to evaluate sleepdisorders. Nevertheless, previous studies commonly used single subjective questionnaires or objective examinations. Therefore, we used the combinations of subjective and objective tools to analyze clinical characteristics of sleep disturbances in PD and investigated differences and consistence between subjective and objective tools. Methods One hundred and sixteen PD patients were eligible to participate into this study. All participants were evaluated by Pittsburgh Sleep Quality Index (PSQI, Unified Parkinson's Disease Rating Scale (UPDRS in "on" condition, Hoehn-Yahr (H-Y stage, Hamilton Depression Rating Scale (HAMD 24 items, Montreal Cognitive Assessment (MoCA, Epworth Sleepiness Scale (ESS, and underwent a video-polysomnography (Video-PSG. Results According to PSQI score of 116 PD patients, the proportion of PD patients with sleep disturbances (PSQI ≥ 7 was 50% (N = 58. Compared to PD patients without sleep disturbances, PD patients with sleep disturbances had lower score of MoCA (23.34 ± 3.50 vs 24.89 ± 3.52; t = 2.377, P = 0.019, higher score of UPDRSⅠ[4.00 (2.00, 5.00 vs 3.00 (2.00, 5.00; U = - 2.306, P = 0.021], UPDRSⅡ[12.00 (9.00, 16.00 vs 10.00 (6.00, 13.00; U = - 1.995, P = 0.046], higher levodopa equivalent daily dose [LED, (508.14 ± 335.85 vs (394.06 ± 236.40 mg/d; t = - 2.115, P = 0.037]. Although PD patients with sleep disturbances had more score of UPDSR Ⅲ and higher H-Y stage, the differences were not significant (P > 0.05. On the other hand, decreased total sleep time (TST, reduced sleep efficiency (SE, increased sleep latency (SL, decreased non-rapid eye movement (NREM sleep stage Ⅱ time were found for PD patients with sleep disturbances (P 0.05, for all. The score of PSQI was positively correlated with the score of ESS (r = 0.200, P = 0

    Discrepancy between subjective and objective measures of sleep is associated with insomnia and increasing age. Cognitive behavioural therapy for insomnia improves sleep quality and decreases subjective-objective sleep discrepancy. This study describes differences between older adults with insomnia and controls in sleep discrepancy, and tests the hypothesis that reduced sleep discrepancy following cognitive behavioural therapy for insomnia correlates with the magnitude of symptom improvement reported by older adults with insomnia. Participants were 63 adults >60 years of age with insomnia, and 51 controls. At baseline, participants completed sleep diaries for 7 days while wearing wrist actigraphs. After receiving cognitive behavioural therapy for insomnia, insomnia patients repeated this sleep assessment. Sleep discrepancy variables were calculated by subtracting actigraphic sleep onset latency and wake after sleep onset from respective self-reported estimates, pre- and post-treatment. Mean level and night-to-night variability in sleep discrepancy were investigated. Baseline sleep discrepancies were compared between groups. Pre-post-treatment changes in Insomnia Severity Index score and sleep discrepancy variables were investigated within older adults with insomnia. Sleep discrepancy was significantly greater and more variable across nights in older adults with insomnia than controls, P ≤ 0.001 for all. Treatment with cognitive behavioural therapy for insomnia was associated with significant reduction in the Insomnia Severity Index score that correlated with changes in mean level and night-to-night variability in wake after sleep onset discrepancy, P sleep discrepancy patterns may guide more targeted treatments for late-life insomnia.

    In the first article in this 2-part series, we outlined a psychobiological model of psychiatric treatment and reviewed the evidence showing psychotherapy to be a form of biological intervention that induces lasting alterations in brain structure and function. In this second article, we focus on the adaptive model of psychopathology, the effectiveness of psychotherapeutic interventions, the synergistic effects of combined psychotherapy and psychopharmacology treatments, and attention to the patient's subjective experience and the doctor-patient alliance to complement an "objective" case formulation. The evidence strongly suggests the need for an integrated treatment approach based on the objective, subjective, and intersubjective science that forms the foundation of psychiatry as a clinical discipline, in which psychotherapy and psychopharmacology are seen as complementary treatments within a systemic approach to psychiatric care and training. What emerges is the integrated psychobiological model of care with a complex treatment matrix unique to each patient-provider pair and comprised of biological, experiential, and relational domains of treatment which form the foundation of psychiatry as a science of attachment and meaning.

    This study investigated whether the Tinetti scale, as a subjective measure for fall risk, is associated with objectively measured gait characteristics. It is studied whether gait parameters are different for groups that are stratified for fall risk using the Tinetti scale. Moreover, the discriminative power of gait parameters to classify elderly according to the Tinetti scale is investigated. Gait of 50 elderly with a Tinneti>24 and 50 elderly with a Tinetti≤24 was analyzed using acceleration-based gait analysis. Validated algorithms were used to derive spatio-temporal gait parameters, harmonic ratio, inter-stride amplitude variability and root mean square (RMS) from the accelerometer data. Clear differences in gait were found between the groups. All gait parameters correlated with the Tinetti scale (r-range: 0.20-0.73). Only walking speed, step length and RMS showed moderate to strong correlations and high discriminative power to classify elderly according to the Tinetti scale. It is concluded that subtle gait changes that have previously been related to fall risk are not captured by the subjective assessment. It is therefore worthwhile to include objective gait assessment in fall risk screening.

    Cancer is the leading cause of death among Chinese, yet little is known about cancer knowledge among this population. The study described the subjective and objective cancer screening knowledge among white- versus blue-collar Chinese midlife adults. A convenient sample of white-collar adults age 40+ years was recruited from government and academic agencies; and blue-collar adults age 40+ years were recruited from manufactory companies in Taiwan. An eight-item cancer screening knowledge test (CSKT) was used to measure objective knowledge and one five-point Likert scale item for assessing subjective (perceived) cancer screening knowledge. A total of 208 white- and 533 blue-collar workers completed the survey during 2008-2011. Mean ages between groups were comparable (41.1 versus 46.3 years), as well as family cancer history (41.5 %). About 76 % of the white-collar and 43 % of the blue-collar adults had college education. The mean score of the CSKT was lower in the blue-collar versus white-collar workers, 5.4 (SD = 1.76) versus 6.1 (SD = 1.40), indicating on average, 68 versus 76 % of the participants answered the cancer knowledge correctly. The subjective knowledge levels were, however, higher among the blue-collar workers (mean rating of 3.22 versus 2.78). The CSKT showed a good mix of relatively easy and moderately difficult items in both groups. Study showed that overall cancer screening knowledge was low among Chinese midlife adults. Although blue-collar workers scored lower on CSKT, the perceived knowledge level was higher. Results also suggest attention to communicating cancer screening information among Chinese blue-collar midlife workers in particular.

Although knowledge about stroke warning signs and risk factors has received considerable attention, objective knowledge on secondary prevention and further self-esteem subjective knowledge have rarely been studied. The aim of our study was to investigate knowledge and treatment decisional role preferences in cerebrovascular patients compared to controls. Methods: We performed a survey on subjective and objective stroke risk knowledge and autonomy preferences in cerebrovascular patients from our stroke outpatient clinic (n=262 and from pedestrians on the street taken as controls during a “World Stroke Day” (n=274. The questionnaire includes measures for knowledge and decisional role preferences from previously published questionnaires and newly developed measures, for example, subjective knowledge, revealed on a visual analog scale. Results: The overall stroke knowledge was low to moderate, with no differences between patients and controls. Knowledge about secondary prevention was particularly low. Only 10%–15% of participants correctly estimated the stroke absolute risk reduction potential of aspirin. The medical data

    Chronic rhinosinusitis with nasal polyposis (NP) represents an invalidating disorder that causes mainly nasal blockage and loss of smell. The aim of this study is to investigate correlations between individual subjective and objective parameters of stable NP disease. 65 NP patients scored their sinonasal symptoms on a visual analogue scale (VAS) and questionnaires (SNOT-22 and SF-36). Peak nasal inspiratory flow (PNIF) measurement, Sniffinatm Sticks (SS) smell test, blood analysis for eosinophilia, total IgE and culture for Staphylococcus aureus (SA) were performed. VAS scores for nasal blockage correlated with the SNOT-22 and SF-36 scores, which was not observed for VAS of other symptoms. VAS scores for nasal blockage correlated well with PNIF values as well as VAS scores for smell dysfunction and SS results (both psmell reduction (psmell reduction in NP disease. Nasal blockage is the only symptom that correlates well with NP size and SNOT-22 scores, whereas smell reduction correlates with blood eosinophilia.

This study examined whether the use of binaural recordings of sound events improves the correlation between the objective metrics and the perceived annoyance, particularly for road traffic noise. Metrics based on measurement with a single...... microphone and on binaural sound field recordings have been examined and compared. In order to acquire data for the subjective perception of annoyance, a series of listening tests has been carried out. It is concluded that binaural loudness metrics from binaural recordings are better correlated......Humans are annoyed when they are exposed to environmental noise. Traditional measures such as sound pressure levels may not correlate well with how humans perceive annoyance, therefore it is important to investigate psychoacoustic metrics that may correlate better with the perceived annoyance...

    Eighteen patients participated in a double-blind, placebo-controlled, single-dose, crossover study of meclofenamate sodium in women with primary dysmenorrhea. Simultaneous evaluations of pain intensity and pain relief, sampling of continuous intrauterine pressure recording, and monitoring of blood meclofenamate levels were carried out. Improvements in pain intensity and pain relief were observed at 45 minutes and reached statistical significance at and beyond 1 hour 45 minutes after meclofenamate therapy. Ten of 14 uterine pressure parameters showed statistically significant responses after drug therapy and 12 of the 14 parameters showed statistically significant differences in time-response patterns. Statistically significant changes were noted as early as 45 minutes after meclofenamate therapy. Statistically significant correlations were found between and among the parameters of blood drug level and the subjective and objective measures. No drug-related adverse effects were found.

    Rett syndrome (RTT) is associated with myriad debilitating health issues and significant motor and communicative impairments. Because of the former there is concern about the possibility of recurrent and chronic pain but because of the latter it remains difficult to determine what pain ‘looks like’ in RTT. This study investigated pain experience and expression using multiple complementary subjective and objective approaches among a clinical RTT sample. Following informed consent, 18 participants (all female) with RTT (mean age= 12.8 years, SD= 6.32) were characterized in terms of pain experience and interference, typical pain expression, and elicited pain behavior during a passive range of motion-like examination procedure. Parents completed the Dalhousie Pain Interview (DPI; pain type, frequency, duration, intensity), the Brief Pain Inventory (BPI; pain interference), and the Non-Communicating Children’s Pain Checklist – Revised (NCCPC-R; typical pain expression). A Pain Examination Procedure (PEP) was conducted and scored using the Pain and Discomfort Scale (PADS). The majority of the sample (89%) were reported to experience pain in the previous week which presented as gastrointestinal (n=8), musculoskeletal (n=5), and seizure related pain (n=5) that was intense (scored 0–10; M= 5.67, SD= 3.09) and long in duration (M= 25.22 hours, SD= 53.52). Numerous pain-expressive behaviors were inventoried (e.g., vocal, facial, mood/interaction changes) when parents reported their child’s typical pain behaviors and based on independent direct observation during a reliably coded pain exam. This study provides subjective and objective evidence that individuals with RTT experience recurring and chronic pain for which pain expression appears intact. PMID:26425056

    Solar energy for the production of electric energy is one source of renewable energy which is experiencing most development in recent years. In countries with high solar radiation indices, as is the case of Spain, expectations of installation of large solar power plants are increasing. Most solar power plants are located in rural environments, where the landscape has remained practically unaltered ever since extensive agriculture was introduced. Because of this, one of the most significant environmental impacts of this type of installation is the visual impact derived from the alteration of the landscape. In this work, an indicator is proposed for the quantification of the objective aesthetic impact, based on four criteria: visibility, colour, fractality and concurrence between fixed and mobile panels. The relative importance of each variable and the corresponding value functions are calculated using expert contribution. A study of the subjective aesthetic impact is then carried out using the semantic differential method, to obtain the perception of a sample of individuals of the initial landscapes and of the landscapes altered through the installation of a solar power plant. The indicator and the study of public perception are applied to five real solar power plants, to test their reliability. Subsequently, a different group of individuals is used to determine preferences between the five solar power plants. The study proves that the combined use of objective indicator and subjective study, faithfully explains user preferences corresponding to the combined comparisons of the five cases. It is concluded that the tools proposed for the evaluation of the aesthetic impact of solar power plants are useful for the selection of optimal plant location and most adequate use of panel technology, to minimise aesthetic impact.

    To correlate the objective cephalometric measurements with subjective facial esthetics in patients with bimaxillary protrusion. The sample consisted of 60 Asian-Chinese patients with bimaxillary protrusion who met the inclusion criteria. The facial esthetics of posttreatment profile and the change of profile on standardized lateral photographs were rated by a panel of 10 orthodontists and a panel of 10 lay persons with bimaxillary protrusion. All of the pretreatment and posttreatment cephalograms were digitized and traced. Twenty-five cephalometric measurements were constructed and analyzed. Correlations between the subjective facial esthetic scores and each cephalometric measurement were evaluated. The cephalometric measurements correlated with the facial esthetic scores of posttreatment profile given by the orthodontist and the lay persons were basically the same. For the evaluation of posttreatment profile in bimaxillary protrusion patients, the upper and lower lip to E-line, upper and lower incisor tip to AP plane, Pg-NB distance, mentolabial angle, and sulcus depth correlated significantly with the esthetic score. For the evaluation of profile change during orthodontic treatment, retraction of upper incisor relative to AP plane or the perpendicular line through sella (line Y), change of upper incisor inclination, change of mentolabial sulcus depth, and retraction of lips relative to E-line were correlated positively with the esthetic value. Cephalometric measurements of lip position, incisor position, and chin morphology were key parameters correlated to facial esthetics.

    The objective of science is to advance knowledge, primarily in two interlinked ways: circulating ideas, and defending or criticizing the ideas of others. Peer review acts as the gatekeeper to these mechanisms. Given the increasing concern surrounding the reproducibility of much published research, it is critical to understand whether peer review is intrinsically susceptible to failure, or whether other extrinsic factors are responsible that distort scientists' decisions. Here we show that even when scientists are motivated to promote the truth, their behaviour may be influenced, and even dominated, by information gleaned from their peers' behaviour, rather than by their personal dispositions. This phenomenon, known as herding, subjects the scientific community to an inherent risk of converging on an incorrect answer and raises the possibility that, under certain conditions, science may not be self-correcting. We further demonstrate that exercising some subjectivity in reviewer decisions, which serves to curb the herding process, can be beneficial for the scientific community in processing available information to estimate truth more accurately. By examining the impact of different models of reviewer decisions on the dynamic process of publication, and thereby on eventual aggregation of knowledge, we provide a new perspective on the ongoing discussion of how the peer-review process may be improved.

    To assess whether a subjective questionnaire that measures the disability caused by balance disorders in daily life activities is correlated to objective assessment of balance in elderly patients with age-related instability. We included 37 subjects aged 65 years or more who presented balance disorders induced solely by age. Balance assessment was through the sensory organisation test and limits of stability of computerised dynamic posturography, the SwayStar system and the modified timed up and go test. The patients also completed the dizziness handicap inventory (DHI) questionnaire. The SwayStar balance control index (BCI) was most significantly correlated to the DHI score and the score of its different scales. When we divided the patients into subgroups according to DHI score, we only found statistically significant differences in the BCI and number of falls. In our population of elderly patients with instability, there is practically no correlation between the DHI and the static balance assessment. However, there is greater correlation with the BCI, which could show that dynamic balance is perceived as more disabling for these patients. In this case, when designing a rehabilitation protocol we should focus more on dynamic activities such as gait.

    Research on personality and adiposity has focused primarily on middle-aged and older adults. The present research sought to (a) replicate these associations in a young adult sample, (b) examine whether sex, race, or ethnicity moderate these associations, and (c) test whether personality is associated with the subjective experience of body weight and discrepancies between perceived and actual weight. Participants (N = 15,669; M(age) = 29; 53% female; ∼40% ethnic/racial minority) from Wave 4 of the National Longitudinal Study of Adolescent Health completed a Five-Factor Model personality measure and reported their weight, height, and perception of weight category (e.g., overweight); trained staff measured participants' height, weight, and waist circumference. Conscientiousness was associated with healthier weight, with a nearly 5 kg difference between the top and bottom quartiles. Neuroticism among women and Extraversion among men were associated with higher adiposity. Neuroticism was also associated with misperceived heavier weight, whereas Extraversion was associated with misperceived taller and leaner. The associations were similar across race/ethnic groups. Personality is associated with objective and subjective adiposity in young adulthood. Although modest, the effects are consistent with life span theories of personality, and the misperceptions are consistent with the conceptual worldviews associated with the traits.

    Although traumatic facial nerve paralysis is a severe handicap, there are no follow-up studies evaluating outcome after primary repair of traumatic facial nerve injuries. From May 1988 to August 2005, 27 patients (mean age, 27 years) were operated for traumatic facial nerve lesions (mean number of affected branches, 2.2). End-to-end facial nerve repair was always performed. All patients were invited to our outpatient clinic for standardized questionnaires (Facial Disability Index, Short Form-36 Health Survey), physical examination (Sunnybrook Facial Grading System), and clinical photographs. Sixteen patients participated in the follow-up study (mean, 9.2 years). Mean Facial Disability Index Physical and Social scores were 86 and 81, respectively, indicating good subjective facial functioning. The mean Sunnybrook Facial Grading System score was 74 indicating adequate facial functioning. Mean physical and mental health scores (Short Form-36 Health Survey) were comparable with normative data. Primary end-to-end repair of traumatic facial nerve injuries results in good long-term objective and subjective functional and emotional outcome.

    An interesting paradox has emerged from the literature regarding schizotypy--defined as the personality organization reflecting a putative liability for schizophrenia--spectrum disorders. Across certain cognitive, emotional, quality of life, and other functional variables, individuals with schizotypy report experiencing relatively severe levels of pathology. However, on objective tests of these same variables, individuals with schizotypy perform largely in the healthy range. These subjective impairments are paradoxical in that individuals with schizotypy, typically recruited from undergraduate college populations, should be healthier in virtually every conceivable measure compared to chronic, older outpatients with severe mental illness. The present study evaluated the idea that the subjective deficits associated with schizotypy largely reflect a lack of illusory superiority bias-a normally occurring bias associated with an overestimation of self-reported positive qualities and underestimation of negative qualities compared to others. In the present study, both state-measured using laboratory emotion-induction methods-and trait positive and negative emotion was assessed across self (e.g., how do you feel at this moment?) and other (e.g., how do most people feel at this moment?) domains in 39 individuals with self-reported schizotypy and 39 matched controls. Controls demonstrated an illusory superiority effect across both state and trait measures whereas individuals with schizotypy did not. These results were not explained by severity of mental health symptoms. These results suggest that a cognitive bias, or lack thereof, is a marker of schizotypy and a potential target for further research and therapy.

  20. Objective and Subjective Evaluation of Reflecting and Diffusing Surfaces in Auditoria

    Cox, Trevor John

    Available from UMI in association with The British Library. Requires signed TDF. The performance of reflectors and diffusers used in auditoria have been evaluated both objectively and subjectively. Two accurate systems have been developed to measure the scattering from surfaces via the cross correlation function. These have been used to measure the scattering from plane panels, curved panels and quadratic residue diffusers (QRDs). The scattering measurements have been used to test theoretical prediction methods based on the Helmholtz-Kirchhoff integral equation. Accurate prediction methods were found for all surfaces tested. The limitations of the more approximate methods have been defined. The assumptions behind Schroeder's design of the QRD have been tested and the local reacting admittance assumption found to be valid over a wide frequency range. It was found that the QRD only produces uniform scattering at low frequencies. For an on-axis source the scattering from a curved panel was as good as from a QRD. For an oblique source the QRD produced much more uniform scattering than the curved panel. The subjective measurements evaluated the smallest perceivable change in the early sound field, the part most influenced by reflectors and diffusers. A natural sounding simulation of a concert hall field within an anechoic chamber was used. Standard objective parameters were reasonable values when compared to values found in real halls and subjective preference measurements. A difference limen was measured for early lateral energy fraction (.048 +/-.005); inter aural cross correlation (.075 +/-.008); clarity index (.67 +/-.13 dB); and centre time (8.6 +/- 1.6 ms). It was found that: (i) when changes are made to diffusers and reflectors, changes in spatial impression will usually be larger than those in clarity; and (ii) acousticians can gain most by paying attention to lateral sound in auditoria. It was also found that: (i) diffuse reflections in the early sound field

    The pupil response discriminates between old and new stimuli, with old stimuli characterized by larger pupil dilation patterns than new stimuli. We sought to explore the cause of the pupil old/new effect and discount the effect of targetness, effort, recollection retrieval, and complexity of the recognition decision. Two experiments are reported in which the pupil response and the eye fixation patterns were measured, while participants identified novel and familiar object stimuli, in two separate tasks, emphasizing either novelty or familiarity detection. In Experiment 1, familiarity and novelty decisions were taken using a rating scale, while in Experiment 2 a simpler yes/no decision was used. In both experiments, we found that detection of target familiar stimuli resulted in greater pupil dilation than the detection of target novel stimuli, while the duration of the first fixation discriminated between familiar and novel stimuli as early as within 320 ms after stimulus onset. Importantly, the pupil response distinguished between the objective (during an earlier temporal component) and the subjective (during a later temporal component) status of the stimulus for misses and false alarms. In the light of previous findings, we suggest that the pupil and fixation old/new effects reflect the distinct neural and cognitive mechanisms involved in the familiarity and novelty decisions. The findings also have important implications for the use of pupil dilation and eye movement patterns to explore explicit and implicit memory processes.

    Abstract Background This article provides new insights into the impact of social engagement on CVD risk factors in older adults. We hypothesized that objective (social participation, social ties and marital status) and subjective (emotional support) aspects of social engagement are independently associated with objective measures of cardiovascular risk. Methods Data from the English Longitudinal Study on Ageing (ELSA) were analyzed. The effects of social participation, social ties, marital status, and emotional support on hypertension, obesity, high sensitivity C-reactive protein, and fibrinogen were estimated by logistic regression controlling for age, sex, education, physical function, depression, cardiovascular disease, other chronic diseases, physical activity, and smoking. Results Social participation is a consistent predictor of low risk for four risk factors, even after controlling for a wide range of covariates. Being married is associated with lower risk for hypertension. Social ties and emotional support are not significantly associated with any of the cardiovascular risk factors. Conclusion Our analysis suggests that participation in social activities has a stronger association with CV risk factors than marital status, social ties or emotional support. Different forms of social engagement may therefore have different implications for the biological risk factors involved.

    Understanding the social determinants of child health is a prominent area of research. This paper examines the measurement of socioeconomic position in a sample of families of children with cancer. Socioeconomic position is difficult to measure in pediatric health research due to sensitivity of asking about finances when research is conducted in health care delivery settings, financial volatility associated with periods of pediatric illness, and difficulty recruiting fathers to research. Caregivers of children with cancer (n=76) completed a questionnaire that included the MacArthur Scale of Subjective Social Status (SSS). SSS was measured using two 10-rung ladders with differing referent groups: the US and respondents' communities. Respondents placed themselves on each ladder by placing an X on the rung that represented their social position in relation to the two referent groups. Individuals' SSS ratings and discrepancies in SSS ratings within couples were examined, and associations with objective social status measures were evaluated using Pearson correlations or t-tests. Parents' placement on the US and community ladders was positively associated with their income, education, wealth, household savings, and household savings minus debt. On average, respondents placed themselves higher on the US ladder compared to the community ladder. There was an average intra-couple discrepancy of 1.25 rungs in partner's placements on the US ladder and a 1.56 rung difference for the community ladder. This intra-couple discrepancy was not associated with gender. Results offer insight into the use of subjective social status measures to capture a more holistic assessment of socioeconomic position and the measurement of socioeconomic position in two-parent families.

Socioeconomic position is difficult to measure in pediatric health research due to sensitivity of asking about finances when research is conducted in health care delivery settings, financial volatility associated with periods of pediatric illness, and difficulty recruiting fathers to research. METHODS: Caregivers of children with cancer (n=76 completed a questionnaire that included the MacArthur Scale of Subjective Social Status (SSS. SSS was measured using two 10-rung ladders with differing referent groups: the US and respondents' communities. Respondents placed themselves on each ladder by placing an X on the rung that represented their social position in relation to the two referent groups. Individuals' SSS ratings and discrepancies in SSS ratings within couples were examined, and associations with objective social status measures were evaluated using Pearson correlations or t-tests. RESULTS: Parents' placement on the US and community ladders was positively associated with their income, education, wealth, household savings, and household savings minus debt. On average, respondents placed themselves higher on the US ladder compared to the community ladder. There was an average intra-couple discrepancy of 1.25 rungs in partner's placements on the US ladder and a 1.56 rung difference for the community ladder. This intra-couple discrepancy was not associated with gender. DISCUSSION: Results offer insight into the use of subjective social status measures to capture a more holistic assessment of socioeconomic position and the measurement of socioeconomic position in two-parent families.

  5. The object of mobile spatial data, the subject in mobile spatial research

    2016-09-01

    Full Text Available With an estimated one billion smartphones producing over 5 petabytes of data a day, the spatially aware mobile device has become a near ubiquitous presence in daily life. Cogent, excellent research in a variety of fields has explored what the spatial data these devices produce can reveal of society, such as analysis of Foursquare check-ins to reveal patterns of mobility for groups through a city. In such studies, the individual intentions, motivations, and desires behind the production of said data can become lost through computational aggregation and analysis. In this commentary, I argue for a rethinking of the epistemological leap from individual to data point through a (reseating of the reflexive, self-eliciting subject as an object for spatial big data research. To do so, I first situate current research on spatial big data within a computational turn in social sciences that relies overly on the data produced as a stand-in for the subject producing said data. Second, I argue that a recent shift within geography and cognate disciplines toward viewing spatial big data as a form of spatial media allows for study of the sociotechnical processes that produce modern assemblages of data and society. As spatial media, the spatial big data created through mobile device use can be understood as the data of everyday life and as part of the sociotechnical processes that produce individuals, data, and space. Ultimately, to understand the data of everyday life, researchers must write thick descriptions of the stories we tell ourselves about the data we give off to others.

  8. From object to subject: hybrid identities of indigenous women in science

    McKinley, Elizabeth

    2008-12-01

    The use of hybridity today suggests a less coherent, unified and directed process than that found in the Enlightenment science's cultural imperialism, but regardless of this neither concept exists outside power and inequality. Hence, hybridity raises the question of the terms of the mixture and the conditions of mixing. Cultural hybridity produced by colonisation, under the watchful eye of science at the time, and the subsequent life in a modern world since does not obscure the power that was embedded in the moment of colonisation. Indigenous identities are constructed within and by cultural power. While we all live in a global society whose consequences no one can escape, we remain unequal participants and globalisation remains an uneven process. This article argues that power has become a constitutive element in our own hybrid identities in indigenous people's attempts to participate in science and science education. Using the indigenous peoples of Aotearoa New Zealand (called Māori) as a site of identity construction, I argue that the move from being the object of science to the subject of science, through science education in schools, brings with it traces of an earlier meaning of `hybridity' that constantly erupts into the lives of Māori women scientists.

    Full Text Available Nowadays dozens of people share their content in the current Web 2.0 space, talk with friends in social networking sites such as Facebook and live on the Net in many other ways. They do all this quite naturally, forgetting the healthy cautiousness sometimes. In real life we rely on trusted people. Do we know how to reflect real-world trust mechanisms into on-line social software? In the article we focused to bring overview on state of the art in main ideas behind a trust processing in online social networking systems. What are common sources of subjective trust, how the trust emerges and what are the sources of trust dynamics? How can be trust captured into the systems, how can be explicit trust processed to infer indirect trust, the trust between users who do not know each other? And what are the ways to infer objective metrics of trust, the reputation or trustworthiness? Finally, we point out selected challenges related to the trust in current highly dynamic social networks.

  10. "Twelve Angry Men". The Group and the Individual: From Objectiveness to Subjectiveness

    2015-12-01

    Full Text Available Screened fiction stirs people’s psyches through emotions, which refer to a virtual world and therefore have the potential to help the individual grow in self-awareness while feeling relatively “safe”. An innovative method to work on movies for education and training purposes was developed by Eugenio Torre, and is proposed here for the film 12 Angry Men. This movie may be used in training settings focused on helping relationships to reflect upon the meaning of being an individual in a group, being a group, responsibility and choice. A key to the reading of the movie is proposed at two different but complementary levels. From an “extra-psychical” standpoint, movie characters may represent a working group of 12 very different people sharing a task, while from an “intra-psychical” one, each character may represent an embodiment or symbol of an individual’s part and/or complex. According to the movie suggestion, we describe a path from objectiveness to subjectiveness and the final accomplishment of an ethical choice.

  11. Feasibility of a walking virtual reality system for rehabilitation: objective and subjective parameters.

    Even though virtual reality (VR) is increasingly used in rehabilitation, the implementation of walking navigation in VR still poses a technological challenge for current motion tracking systems. Different metaphors simulate locomotion without involving real gait kinematics, which can affect presence, orientation, spatial memory and cognition, and even performance. All these factors can dissuade their use in rehabilitation. We hypothesize that a marker-based head tracking solution would allow walking in VR with high sense of presence and without causing sickness. The objectives of this study were to determine the accuracy, the jitter, and the lag of the tracking system and its elicited sickness and presence in comparison of a CAVE system. The accuracy and the jitter around the working area at three different heights and the lag of the head tracking system were analyzed. In addition, 47 healthy subjects completed a search task that involved navigation in the walking VR system and in the CAVE system. Navigation was enabled by natural locomotion in the walking VR system and through a specific device in the CAVE system. An HMD was used as display in the walking VR system. After interacting with each system, subjects rated their sickness in a seven-point scale and their presence in the Slater-Usoh-Steed Questionnaire and a modified version of the Presence Questionnaire. Better performance was registered at higher heights, where accuracy was less than 0.6 cm and the jitter was about 6 mm. The lag of the system was 120 ms. Participants reported that both systems caused similar low levels of sickness (about 2.4 over 7). However, ratings showed that the walking VR system elicited higher sense of presence than the CAVE system in both the Slater-Usoh-Steed Questionnaire (17.6 ± 0.3 vs 14.6 ± 0.6 over 21, respectively) and the modified Presence Questionnaire (107.4 ± 2.0 vs 93.5 ± 3.2 over 147, respectively). The marker-based solution provided accurate

    Personality and social support (SS) influence risk for depression and modify its outcome through multiple pathways. The impact of personality dimensions neuroticism and extraversion on SS among patients with major depressive disorder (MDD) has been little studied. In the Vantaa Depression Study, we assessed neuroticism and extraversion with the Eysenck Personality Inventory, objective SS with the Interview Measure of Social Relationships, and subjective SS with the Perceived Social Support Scale-Revised at baseline, at 6 and 18 months among 193 major depressive disorder patients diagnosed according to the fourth edition of Diagnostic and Statistical Manual of Mental Disorders (DMS-IV). At all time-points, low neuroticism and high extraversion associated significantly with between-subject differences in levels of objective and subjective SS. Lower neuroticism (beta = 0.213, p = 0.003) and higher extraversion (beta = 0.159, p = 0.038) predicted greater within-subject change of subjective, but not objective SS. Thus, neuroticism and extraversion associated with the size of objective and subjective SS and predicted change of subjective SS. Modification of subjective SS, particularly, may indirectly influence future vulnerability to depression.

    This study aims to investigate early voice changes after total thyroidectomy, to assess the improved parameters in intermediate postoperative intervals, to evaluate the effect of age on voice after thyroidectomy, and to determine the correlation between the objective and the subjective method outcomes. This is a prospective, nonrandomized study. One hundred ninety-one participants, divided into two age groups, underwent three full voice assessments (preoperatively and 1 and 8 weeks after thyroidectomy) by means of videostroboscopy, perceptual evaluation, acoustic analysis, aerodynamic evaluation, and a self-evaluation questionnaire. Two control groups enrolled in the study: (1) patients with an indication of neck surgery not related to laryngeal nerve injury risk or strap muscle dissection and (2) patients with an indication of a non-neck surgery. No statistically significant difference was found in any voice parameter, between preoperative and 1-week postoperative assessment regarding the control groups. A statistically significant difference was found between preoperative evaluation and 1 week after thyroidectomy for the total study population, as well as for the ≥40 years' age subgroup for all parameters evaluated except for shimmer. The <40 years' age subgroup showed a statistically significant difference in pitch, maximum phonation time, and grade, roughness, breathiness, asthenia, and strain (GRBAS) score between preoperative evaluation and 1 week after thyroidectomy. None of the parameters showed a statistical significant difference in the <40 years' age subgroup at 8 weeks' evaluation. The Voice Handicap Index (VHI) score correlated significantly with the GRBAS score preoperatively and postoperatively at 1 and 8 weeks' evaluations. Furthermore, VHI correlated significantly with pitch a week postoperatively. GRBAS scores showed significant correlation not only with VHI but also with acoustic parameters including pitch, shimmer, and noise-to-harmonic ratio

    To investigate the impact of the gap between subjective and objective social status on health-related quality of life. We analyzed data from 12,350 participants aged ≥ 18 years in the Korean Health Panel Survey. Health-related quality of life was measured by EuroQol-Visual analogue scale. Objective (income and education) and subjective social class (measured by MacArthur scale) was classified into three groups (High, Middle, Low). In terms of a gap between objective and subjective social class, social class was grouped into nine categories ranging from High-High to Low-Low. A linear mixed model was used to investigate the association between the combined social class and health-related quality of life. The impact of the gap between objective and subjective status on Health-related quality of life varied according to the type of gap. Namely, at any given subjective social class, an individual's quality of life declined with a decrease in the objective social class. At any given objective social class (e.g., HH, HM, HL; in terms of both education and income), an individual's quality of life declined with a one-level decrease in subjective social class. Our results suggest that studies of the relationship between social class and health outcomes may consider the multidimensional nature of social status.

    To elucidate the relationship between subjective complaints and polysomnographical parameters in psychosomatic patients. A convenience sample of patients from a psychosomatic inpatient unit were classified according to the Pittsburgh Sleep Quality Index (PSQI) as very poor sleepers (PSQI >10, n=80) and good sleepers (PSQI subjective feeling of current well-being in the morning and subjective TST and negatively with subjective restfulness, subjective sleep onset latency, subjective evaluation of sleep onset latency, and evaluation of time awake after sleep onset. The data suggest that, in general, patients selected from the extremes of reported very poor sleepers and good sleepers have different amounts of sleep when measured in the laboratory, and that in general, the amount and timing of sleep in the laboratory are quite well perceived and reported by these groups. The data came from psychosomatic patients and suggest that even in this patient group, respective sleep complaints are more than just the expression of general somatization or lamenting.

    The role of physical activity as a factor that protects against stress-related mental disorders is well documented. Nevertheless, there is still a dearth of research using objective measures of physical activity. The present study examines whether objectively assessed vigorous physical activity (VPA) is associated with mental health benefits beyond moderate physical activity (MPA). Particularly, this study examines whether young adults who accomplish the American College of Sports Medicine's (ACSM) vigorous-intensity exercise recommendations differ from peers below these standards with regard to their level of perceived stress, depressive symptoms, perceived pain, and subjective and objective sleep. A total of 42 undergraduate students (22 women, 20 men; M=21.24years, SD=2.20) volunteered to take part in the study. Stress, pain, depressive symptoms, and subjective sleep were assessed via questionnaire, objective sleep via sleep-EEG assessment, and VPA via actigraphy. Meeting VPA recommendations had mental health benefits beyond MPA. VPA was associated with less stress, pain, subjective sleep complaints and depressive symptoms. Moreover, vigorous exercisers had more favorable objective sleep pattern. Especially, they had increased total sleep time, more stage 4 and REM sleep, more slow wave sleep and a lower percentage of light sleep. Vigorous exercisers also reported fewer mental health problems if exposed to high stress. This study provides evidence that meeting the VPA standards of the ACSM is associated with improved mental health and more successful coping among young people, even compared to those who are meeting or exceeding the requirements for MPA.

    The aim of this study was to illustrate the relationship between objective and subjective measures of quality of life (QOL) and to identify the factors influencing QOL in a sample of middle-aged and elderly female patients with schizophrenia in Japan. Middle-aged and elderly female inpatients with schizophrenia (n=66; mean age [SD]: 68.0 [8.0]) were assessed using the Quality of Life Scale (QLS), Lancashire Quality of Life Profile (LQLP), Positive and Negative Symptoms Scale (PANSS), and Rehabilitation Evaluation Hall and Baker (REHAB). Correlation analyses among the measures and regression analyses of objective and subjective QOL measures (QLS and LQLP) were conducted. Explanations of results for the two types of QOL measures in terms of psychotic symptomatology and adjustment variables (PANSS and REHAB) are discussed. There was no salient correlation between objective and subjective QOL measures. The regression analyses identified PANSS anergia and REHAB community skills as factors influencing objective QOL, whereas PANSS depression and paranoid/belligerence were factors influencing subjective QOL. Results indicated that objective and subjective QOL domains should be treated separately in clinical practice for this patient population. Some QOL factors identified in the regression analyses can be used as targets to improve QOL. The findings have important clinical implications for the assessment and treatment of this patient population. Copyright © 2013 Elsevier B.V. All rights reserved.

    Background Children with specific language impairment (SLI) show particular difficulty comprehending and producing object (Who did the bear follow?) relative to subject (Who followed the tiger?) wh-questions. Aims To determine if school-age children with SLI, relative to children with typical development (TD), show a more distinct unevenness, or asymmetry, in the comprehension of these questions. In addition, this study examined whether the sustained left-anterior negativity (LAN) in event-related potentials (ERP) could be used as a marker for atypical processing of these questions in children with SLI. The LAN effect signals the greater working memory processes for maintaining in memory the dislocated object in object wh-questions and reflects working memory capacity in adults. It was predicted that the amplitude of the LAN would be greater in children with SLI, reflecting the characteristic low working memory capacity in this population. The concomitance of these behavioural and electrophysiological effects would suggest that the subject–object asymmetry in SLI should be investigated in relation to poor working memory skills. Methods & Procedures Groups including 13 children with SLI, 17 same-age TD children and 18 normal adults completed an auditory sentence comprehension task requiring button responses while continuous electroencephalography (EEG) was collected. Accuracy for subject and object questions was calculated. The mean amplitude values of the ERP data for the wh-questions were examined to identify differential processing of subject and object questions. Outcomes & Results TD children demonstrated asymmetrical comprehension of subject and object wh-questions, whereas children with SLI comprehended both question types poorly and adults did not show subject–object asymmetry. ERP waveforms spanning the wh-dependency revealed a large and widespread sustained anterior positivity for object relative to subject questions in the TD group, indicating

    Today, many procedures for assessing the indoor environment rely on both subjective and objective indicators (e.g. ANSI/ASHRAE 55-2004; ISO 10551). It is however unclear how these two types of measurements are related to perceived comfort. This article aims at assessing the relative utility of subjective (rating scale measures) and objective indicators of perceived comfort of indoor environments. In a hospital setting, physical environmental variables (e.g. temperature, relative humidity and noise level) were simultaneously measured as respondents (both patients and staff) rated their perception of the indoor environment. Regression analyses indicated that the subjective sensory ratings were significantly better than objective indicators at predicting overall rated indoor comfort. These results are discussed in relation to existing measurement procedures and standards. (author)

    This study employed a perceptual-motor task of figure copying in 27 cocaine-dependent, 26 marijuana-abusing or dependent, and 33 healthy subjects. Cocaine-dependent and healthy individuals did not differ in their scores on the copying of a two-dimensional diamond and a cross. In contrast, cocaine-dependent subjects displayed significantly poorer ability to copy a three-dimensional Necker cube, a smoking pipe, a hidden line elimination cube, a pyramid, and a dissected pyramid. Marijuana users' performance on all copied figures was comparable to that of the healthy comparison subjects. Considering that decreased three-dimensional copying ability has been found to be associated with fatal injuries, further studies are needed to investigate possible underlying mechanisms (e.g., parietal lobe damage) and their role in the pathophysiology of cocaine dependence.

  7. Bootstrap Signal-to-Noise Confidence Intervals: An Objective Method for Subject Exclusion and Quality Control in ERP Studies

    2016-01-01

    Analysis of event-related potential (ERP) data includes several steps to ensure that ERPs meet an appropriate level of signal quality. One such step, subject exclusion, rejects subject data if ERP waveforms fail to meet an appropriate level of signal quality. Subject exclusion is an important quality control step in the ERP analysis pipeline as it ensures that statistical inference is based only upon those subjects exhibiting clear evoked brain responses. This critical quality control step is most often performed simply through visual inspection of subject-level ERPs by investigators. Such an approach is qualitative, subjective, and susceptible to investigator bias, as there are no standards as to what constitutes an ERP of sufficient signal quality. Here, we describe a standardized and objective method for quantifying waveform quality in individual subjects and establishing criteria for subject exclusion. The approach uses bootstrap resampling of ERP waveforms (from a pool of all available trials) to compute a signal-to-noise ratio confidence interval (SNR-CI) for individual subject waveforms. The lower bound of this SNR-CI (SNRLB) yields an effective and objective measure of signal quality as it ensures that ERP waveforms statistically exceed a desired signal-to-noise criterion. SNRLB provides a quantifiable metric of individual subject ERP quality and eliminates the need for subjective evaluation of waveform quality by the investigator. We detail the SNR-CI methodology, establish the efficacy of employing this approach with Monte Carlo simulations, and demonstrate its utility in practice when applied to ERP datasets. PMID:26903849

    This paper tries to explore the importance and measurement of the subject-object dichotomy based on analysis of its necessity, and concludes that the subject-object dichotomy is the needs of social development and the inevitable result of the interaction between the enhanced human transformation energy and its interaction of the outside world. The subject-object contradictory concepts of the material-oriented or mankind-centered thoughts cannot help achieve the sustainable development of human society. The fundamental solution to the subject-object contradiction lies in keeping the concept of people-centered development and maintaining the subject-object dialectical tension in an active pursuit of the nature-human harmony in the post subject-object relationship.%在分析主(体)客(体)二分必要性的基础上,探讨主客二分"度"的重要性及其把握的途径。认为主客二分是社会发展的需要,是人改造世界能力的提升以及与外部世界互动的必然结果。以物为本和人类中心主义这两种将主客体根本对立的观念,都难以实现人类社会的可持续发展。只有坚持以人为本的发展观,保持主客体二者的辩证张力,积极追求"后主客关系的天人合一",大力弘扬社会主义文化,提升人的精神境界,才是解决主客矛盾的根本之路。

    Presentation of images with known pathology similar to that of a new unknown lesion would be helpful for radiologists in their diagnosis of breast cancer. In order to find images that are really similar and useful to radiologists, we determined the radiologists' subjective similarity ratings for pairs of masses, and investigated objective similarity measures that would agree well with the subjective ratings. Fifty sets of images, each of which included one image in the center and six other images to be compared with the center image, were selected; thus, 300 pairs of images were prepared. Ten breast radiologists provided the subjective similarity ratings for each image pair in terms of the overall impression for diagnosis. The objective similarity measures based on cross-correlation of the images, differences in feature values, and psychophysical measures by use of an artificial neural network were determined. The objective measures based on the cross-correlation were found to be not correlated with the subjective similarity ratings (r 0.40). When several image features were used, the differences-based objective measure was moderately correlated (r = 0.59) with the subjective ratings. The relatively high correlation coefficient (r = 0.74) was obtained for the psychophysical similarity measure. The similar images selected by use of the psychophysical measure can be useful to radiologists in the diagnosis of breast cancer.

    The relationship between socioeconomic status (SES) and health changes as a society develops. In developed countries, high SES is associated with better health, but in developing countries, high SES is associated with poorer health. However, measuring SES is difficult in countries like India, where the traditional class and caste system are interwoven and complex. The current study explored the relationship between subjective and objective indices of SES and between SES and the metabolic syndrome among Asian Indians residing in Mumbai, India. Participants were a subset of young adults (N = 112, median age 19 years, 24% male) who were part of larger study assessing psychosocial correlates of the metabolic syndrome. SES was assessed through objective (father's education) and subjective (SES ladder) indices. Data indicated that high subjective SES was correlated with fasting blood sugar (r = .28, P < .003), and father's education was correlated with high cholesterol (r = .32, P < .005). Subjective and objective indices of SES were also correlated with each other (r = .24, P < .04). These data reiterate that the link between SES and health is obvious from an early age, regardless of the measures used to assess SES. Given the complexity of assessing SES in developing countries, objective subjective indices should be used in assessing SES.

    The main focus of this essay is to closely engage with the role of scientist-subjectivity in the making of objectivity in Lorraine Daston and Peter Galison's book Objectivity, and Daston's later and earlier works On Scientific Observation and The Moral Economy of Science. I have posited four challenges to the neo-Kantian and Foucauldian constructions of the co-implication of psychology and epistemology presented in these texts. Firstly, following Jacques Lacan's work, I have argued that the subject of science constituted by the mode of modern science suffers from paranoia. It is not the fear of subjectivity interfering with objectivity but the impossibility of knowing the truth of the real that causes paranoia. Here, I have argued that it is not the ethos of objectivity that drives epistemology as Daston and Galison suggest, but the pathos of paranoia. The second challenge builds upon Kant's own denial that the perfect correspondence between the human will and the moral law is possible. Kant himself thought that an ethical human act is impossible without the component of "pathology." This questions Daston and Galison's argument that there is always ethical imperative at the core of epistemic virtue. The third challenge contests the way Daston and Galison take appearance for being in their application of the Foucauldian concept of technologies of the self in modeling the master scientist-self. The fourth challenge questions the notion of the psychological and unconscious in the making of epistemology in Daston's later and earlier work. Against this background, I aim to make a claim that understanding and disclosing "entities" in the scientific domain presupposes an understanding of "being" in general. My goal is to open up the discussion for an alternative conception of the scientist-subject and thereby an affective and existential formulation of science.

    The subjective experience of cognitive dysfunction ("fibrofog") is common in fibromyalgia. This study investigated the relation between subjective appraisal of cognitive function, objective cognitive task performance, and brain activity during a cognitive task using functional magnetic resonance imaging (fMRI). Sixteen fibromyalgia patients and 13 healthy pain-free controls completed a battery of questionnaires, including the Multiple Ability Self-Report Questionnaire (MASQ), a measure of self-perceived cognitive difficulties. Participants were evaluated for working memory performance using a modified N-back working memory task while undergoing Blood Oxygen Level Dependent (BOLD) fMRI measurements. Fibromyalgia patients and controls did not differ in working memory performance. Subjective appraisal of cognitive function was associated with better performance (accuracy) on the working memory task in healthy controls but not in fibromyalgia patients. In fibromyalgia patients, increased perceived cognitive difficulty was positively correlated with the severity of their symptoms. BOLD response during the working memory task did not differ between the groups. BOLD response correlated with task accuracy in control subjects but not in fibromyalgia patients. Increased subjective cognitive impairment correlated with decreased BOLD response in both groups but in different anatomic regions. In conclusion, "fibrofog" appears to be better characterized by subjective rather than objective impairment. Neurologic correlates of this subjective experience of impairment might be separate from those involved in the performance of cognitive tasks.

    Full Text Available Un-myelinated C tactile afferents (CT afferents are a key finding in affective touch. These fibres, which activate in response to a caress-like touch to hairy skin (CT afferents are not found in palm skin, may have more in common with interoceptive systems encoding body ownership, than afferent systems processing other tactile stimuli. We tested whether subjective embodiment of a rubber hand (measured through questionnaire items was increased when tactile stimulation was applied to the back of the hand at a rate optimal for CT afferents (3cm/s vs. stimulation of glabrous skin (on the palm of the hand or at a non-optimal rate (30cm/s, which should not activate these fibres. We also collected ratings of tactile pleasantness and a measure of perceived limb position, proprioceptive drift, which is mediated by different mechanisms of multisensory integration than those responsible for feelings of ownership. The results of a multiple regression analysis revealed that proprioceptive drift was a significant predictor of subjective strength of the illusion when tactile stimuli were applied to the back of the hand, regardless of stroking speed. This relationship was modified by pleasantness, with higher ratings when stimulation was applied to the back of the hand at the slower vs. faster stroking speed. Pleasantness was also a unique predictor of illusion strength when fast stroking was applied to the palm of the hand. However, there were no conditions under which pleasantness was a significant predictor of drift. Since the illusion was demonstrated at a non-optimal stroking speed an integrative role for CT afferents within the illusion cannot be fully supported. Pleasant touch, however, does moderate the subjective aspects of the rubber hand illusion, which under certain tactile conditions may interact with proprioceptive information about the body or have a unique influence on subjective body perception.

    Motion tracking systems are commonly used in virtual reality-based interventions to detect movements in the real world and transfer them to the virtual environment. There are different tracking solutions based on different physical principles, which mainly define their performance parameters. However, special requirements have to be considered for rehabilitation purposes. This paper studies and compares the accuracy and jitter of three tracking solutions (optical, electromagnetic, and skeleton tracking) in a practical scenario and analyzes the subjective perceptions of 19 healthy subjects, 22 stroke survivors, and 14 physical therapists. The optical tracking system provided the best accuracy (1.074 ± 0.417 cm) while the electromagnetic device provided the most inaccurate results (11.027 ± 2.364 cm). However, this tracking solution provided the best jitter values (0.324 ± 0.093 cm), in contrast to the skeleton tracking, which had the worst results (1.522 ± 0.858 cm). Healthy individuals and professionals preferred the skeleton tracking solution rather than the optical and electromagnetic solution (in that order). Individuals with stroke chose the optical solution over the other options. Our results show that subjective perceptions and preferences are far from being constant among different populations, thus suggesting that these considerations, together with the performance parameters, should be also taken into account when designing a rehabilitation system.

    The aim of this study was to analyze the efficiency of the voice therapy in children with vocal nodules by using the acoustic analysis and subjective assessment. Thirty-nine patients with vocal fold nodules, aged between 7 and 14, were included in the study. Each subject had voice therapy led by an experienced voice therapist once a week. All diagnostic and follow-up workouts were performed before the voice therapy and after the third or the sixth month. Transoral and/or transnasal videostroboscopic examination and acoustic analysis were achieved using multi-dimensional voice program (MDVP) and subjective analysis with GRBAS scale. As for the perceptual assessment, the difference was significant for four parameters out of five. A significant improvement was found in the acoustic analysis parameters of jitter, shimmer, and noise-to-harmonic ratio. The voice therapy which was planned according to patients' needs, age, compliance and response to therapy had positive effects on pediatric patients with vocal nodules. Acoustic analysis and GRBAS may be used successfully in the follow-up of pediatric vocal nodule treatment.

    A new definition of environmental security gives equal importance to the objective and subjective assessments of environmental risk. In this framework, the management of tourist harbors has to take into account managers' perceptions. The subject of the present study is a tourist harbor in southern Italy where six different managers are present. This paper aims to assess subjectively and objectively the environmental risks associated with the harbor, and to compare the results to provide estimates of environmental security. Hereby managers have been interviewed and a simple model is used for making preliminary assessment of environmental risks. The comparison of the results highlighted a common mismatch between risk perception and risk assessment. We demonstrated that the old part of the harbor is less secure than the new part. In addition, one specific manager representing a public authority showed a leading role in ensuring the environmental security of the whole harbor.

    At present, the number of the vehicle requirements has been continuously increasing. These requirements can be related to the customer as well as the technical requirements. Among these, the "feeling of space" of the occupants inside the vehicles can be regarded as one of the most important factors. In this respect, the driver and passengers should be able to experience positive feeling of space inside the vehicle. There are numerous factors that can influence the sense of space inside the vehicle. These include geometry (vehicle dimensions), light exposure, ambient lights, colors, material selection and material surface. Depending on the selection, the sense of space can be dramatically influenced by these factors. In general, human feeling is subjective and cannot be measured by any instrument. The measure can nevertheless be carried out by utilizing the method of subjective evaluation. Throughout the experiments, the method of evaluation is developed and the factors which can influence the interior feeling are analyzed. In this process, psychological perception, architectural aspects and anthropometry are considered and knowledge from the other domains is transferred in the form of a multidisciplinary approach. The experiments with an aim to evaluate the overall sense of space in the vehicle are carried out based on the physical mock up of BMW 1 series (E87). The space perception with different interior dimensions and anthropometric data of test persons are also analyzed. The use of Computer Aided Technology was shown by CATIA V5, PCMAN and RAMSIS. The results show a good correlation between the subjective evaluation and the geometric values.

    Background: The study mentioned was aimed to examine the contribution of the objective measures representing anterior-posterior (AP) and vertical characteristics, dental esthetics, or their combination that are used in daily orthodontic practice in the assessment of the facial esthetics. Materials and Methods: A panel of 64 laypersons evaluated the facial esthetics of 32 boys and 32 girls, stratified over four different angle classes, on a visual analog scale. The relationship between the objective parameters and facial esthetics was evaluated by the backward multiple regression analysis. Results: Dental esthetics, expressed by the esthetic component of the index of orthodontic treatment need (AC/IOTN), appeared to be the most vital indicator for facial esthetics. The horizontal sum, a variable for AP characteristics of the patient, could be a better variable when compared with the overjet. Conclusion: Addition of this newly defined parameter to the AC/IOTN improved the prognostic value from 25% to 35%. PMID:28123267

  9. Placebo-associated improvements in motor function: comparison of subjective and objective sections of the UPDRS in early Parkinson's disease.

    The Unified Parkinson's Disease Rating Scale (UPDRS) is primarily composed of an investigator-derived objective rating of motor function and a patient-derived assessment of activities of daily living (ADL). Using a stringent definition of placebo effect, we examined the frequency, temporal development, and stability of improvements during placebo treatment over 6 months in a large placebo-controlled trial of deprenyl and tocopherol in early Parkinson's disease (DATATOP). One hundred ninety-nine subjects received placebo treatment in the randomized, multicenter, placebo-controlled DATATOP study. We compared the baseline UPDRS motor section scores with follow-up scores at 4, 13, and 26 weeks. Placebo-associated improvement was defined as an improvement over baseline score in motor UPDRS of at least 50% or a change in at least two motor items at any one visit by two or more points. Seventeen percent of the 185 subjects who qualified for analysis met the placebo response criteria. The group prevalence of response was steady (7% to 10%) at any one visit without a marked predominance of an early study effect. Older subjects with more motor impairment at baseline were most likely to show a placebo-associated improvement. ADL scores were low throughout the study, and ADL improvements did not identify the subjects with objectively defined placebo-associated improvement. Prominent improvements in investigator-derived objective measures of Parkinson's disease motor impairment occur during clinical trials, including one that was not aimed at showing improved short-term efficacy. Although the notion of placebo effect often implies patient-based perceptions, we found subjective changes to be infrequent in placebo-treated patients, suggesting that either: (1) the placebo effect was rater-driven; (2) the ADL questionnaire is insensitive to transient but objectively demonstrable motor changes; or (3) that the objective changes, albeit major, are within the realm of natural

    Several studies have explored brain computer interface (BCI) systems based on auditory stimuli, which could help patients with visual impairments. Usability and user satisfaction are important considerations in any BCI. Although background music can influence emotion and performance in other task environments, and many users may wish to listen to music while using a BCI, auditory, and other BCIs are typically studied without background music. Some work has explored the possibility of using polyphonic music in auditory BCI systems. However, this approach requires users with good musical skills, and has not been explored in online experiments. Our hypothesis was that an auditory BCI with background music would be preferred by subjects over a similar BCI without background music, without any difference in BCI performance. We introduce a simple paradigm (which does not require musical skill) using percussion instrument sound stimuli and background music, and evaluated it in both offline and online experiments. The result showed that subjects preferred the auditory BCI with background music. Different performance measures did not reveal any significant performance effect when comparing background music vs. no background. Since the addition of background music does not impair BCI performance but is preferred by users, auditory (and perhaps other) BCIs should consider including it. Our study also indicates that auditory BCIs can be effective even if the auditory channel is simultaneously otherwise engaged. PMID:27790111

    Abstract The surface area of human primary visual cortex (V1) varies substantially between individuals for unknown reasons.

Because such illusions dissociate conscious perception from physical stimulation, our findings indicate that the surface area of V1 predicts variabilit...

    Many digital image applications like digitization of cultural heritage for preservation purposes operate with compressed files in one or more image observing steps. For this kind of applications JPEG compression is one of the most widely used. Compression level, final file size and quality loss are parameters that must be managed optimally. Although this loss can be monitored by means of objective image quality measurements, the real challenge is to know how it can be related with the perceived image quality by observers. A pictorial image has been degraded by two different procedures. The first, applying different levels of low pass filtering by convolving the image with progressively broad Gauss kernels. The second, saving the original file to a series of JPEG compression levels. In both cases, the objective image quality measurement is done by analysis of the image power spectrum. In order to obtain a measure of the perceived image quality, both series of degraded images are displayed on a computer screen organized in random pairs. The observers are compelled to choose the best image of each pair. Finally, a ranking is established applying Thurstone scaling method. Results obtained by both measurements are compared between them and with other objective measurement method as the Slanted Edge Test.

    2013-01-01

    The hypothesis of this study was that juvenile pubic symphysiodesis (JPS) results in pelvic changes that can be identified radiographically in adult dogs. The medical records at the Clinica Veterinaria Vezzoni were searched for standard ventro-dorsal views of the pelvis of adult Labrador and Golden Retrievers that had undergone JPS or had not undergone surgery. The objective assessment of radiographs included the analysis of various pelvic measurements. Subjective evaluation of radiographs was undertaken by 18 specialists and 21 general practitioners and was based on five criteria relating to 1) the acetabular fossae, 2) the pubic symphysis, 3) the margin of the cranial pubic area, 4) the pubic rami, and 5) the obturator foramen. The radiographs of 42 Labrador Retrievers and 16 Golden Retrievers were evaluated. The most useful criteria were the radiographic measurement of the shape of the obturator foramen and two different ratios of length to width of the pubic rami; these values were significantly smaller in dogs after JPS. The pelvic canal width was the same in both groups. All objective measurements were repeatable within and between evaluators. The most reliable subjective criterion was number 4, followed by number 5 in Golden Retrievers and by 2 in Labrador Retrievers. Our objective and subjective evaluations were simple and yielded useful and repeatable results. There was no significant difference between general practitioners and specialists with regard to subjective evaluation, which indicates that these evaluation criteria can be used by small animal clinicians after minimal training.

    This study examined the burden on family members of patients with schizophrenia in a Chilean community. Sixty-five caregivers underwent the Subjective and Objective Family Burden Interview. The results showed moderate to high levels of subjective burden and low levels of support from others in providing care. Burden and containment of disturbed behaviour were correlated with worse relationships between patients and caregivers, with the latter spending less time working outside the home. The assessed sample showed a similar pattern of burden to that of caregivers from developed countries; however, the extent of the burden tended to be higher in Chilean caregivers.

    Full Text Available OBJECTIVE: To compare the voice quality of women with idiopathic Parkinson's disease and those without it. METHODS: An evaluation was performed including 19 female patients diagnosed with idiopathic Parkinson's disease, with an average age of 66 years, and 27 women with an average of 67 years-old in the Control Group. The assessment was performed by computed acoustic analysis and perceptual evaluation. RESULTS: Parkinson's disease patients presented moderate rough and unstable voice quality. The parameters of grade, roughness, and instability had higher scores in Parkinson's disease patients with statistically significant differences. Acoustic measures of Jitter and period perturbation quotient (PPQ significantly differ between groups. CONCLUSIONS: Parkinson's disease female individuals showed more vocal alterations compared to the Control Group, when both perceptual and acoustic evaluations were analyzed.

  20. [THE LEGAL STATUS OF ELEMENTS AND PRODUCTS OF THE HUMAN BODY: OBJECT OR SUBJECT OF LAW?].

    The 2004 Act on bioethics has amended the 1994 Act regarding the donation and the use of elements and products of the human body, medically assisted procreation and prenatal diagnosis. The very purpose of these laws led the legislature not to attempt the summa divisio order distinguishing the object to the person. The analysis of bioethical laws reveals the consecration of the non-commercialization of the human body at the expense of its unavailability. Bioethical laws appear to be catalysts of biological scientific advances releasing the status of the components and the products of the human body while framing it. By limiting scientific opportunities, they prevent human beings from trying to play the sorcerer's apprentice.

    Full Text Available Maximal effort on a 30 km Time Trial (TT30 was examined to assess whether it would elicit changes in objective and subjective tests of the participants' perception of the environment and their ability to anticipate future occurrences (situation awareness; SA and to determine the effect of post-exercise recovery on SA. Nine experienced (5.22 ± 2.77 years road cyclists had their objective and subjective levels of SA assessed prior to and at the completion of two TT30. The participants' results were compared to measurements of maximal oxygen uptake (VO2max, peak power output (PPO, age and years of competitive cycle racing experience. Fatigue resulting from maximal effort on a TT30 produced significant changes in both the objective and subjective test of SA. Effect sizes of 0.93 and 0.99 indicated that the first and second TT30 were likely or almost certain to have a beneficial effect on the objective assessment of SA. However, the effect sizes of 0.97 and 0.95 relating to the subjective assessment of cognitive performance on the first and second TT30 showed that it was very likely the participants' had an increased difficulty in maintaining SA. A recovery period of up to three minutes post TT30 had no effect on SA. Changes in SA had no relationship with measurements of VO2max, peak power output (PPO, age and years of competitive cycle racing experience. The findings suggest that within a laboratory environment, participants consistently underestimate their ability to make accurate assessments of their cycling environment compared to objective measures of their SA

    Computerized linguistic measures of emotional engagement, and reflective and affective language, previously applied to session transcripts, were applied to notes of 14 treatments by candidates under supervision at the New York Psychoanalytic Society and Institute, covering the five decades from the 1950s to the 1990s. The findings indicate a strong relationship between candidates' subjective experience as represented unintentionally in the linguistic style of their case notes and the effectiveness of their clinical work. The treatments were evaluated for effectiveness by experienced clinicians using the Global Assessment of Functioning (GAF) and the Psychodynamic Functioning Scales of Høglend and colleagues; a Composite Clinical Effectiveness (CCE) measure was constructed based on level and change in these measures. The Mean High Weighted Referential Activity Dictionary (MHW), a computerized measure of emotional engagement developed in the framework of Bucci's theory of multiple coding and the referential process, showed a positive correlation of .73 with CCE. The Hostility subcategory of the Negative Affect Dictionary (ANH) showed a negative correlation, -.48, with CCE. In a multiple regression analysis, these two variables accounted for over three-quarters of the variance in the CCE. Implications of the findings for process/outcome research and supervision and evaluation of trainees are discussed.

    We examined 12 transfemoral amputees, 6 using the IRC socket and 6 the QL socket, to confirm whether the ischial-ramal containment (IRC) socket is truly superior to the quadrilateral (QL) socket. In subjective evaluation, the IRC group was significantly better in the total score and in items of comfort, that is, to sit on a chair and lumbar lordosis at heel off (Mann-Whitney test, P 0.05). By X-ray, the stump of the IRC group was maintained significantly more adducted during one foot standing on the prosthesis (Mann-Whitney test, P 0.05), and a multiple regression analysis revealed that the stump length ratio and lateral force ratio during mid-stance were significant explanatory variables for predicting PCI (adjusted R square: 0.87, F-value: 11.85, P socket is a tender feeling of the stump, but that the metabolic efficiency is not superior to the QL socket at the most comfortable speed.

    Assessing thermal comfort becomes more relevant when the aim is to maximise learning and productivity performances, as typically occurs in offices and schools. However, if, in the offices, the Fanger model well represents the thermal occupant response, then on the contrary, in schools, adaptive mechanisms significantly influence the occupants' thermal preference. In this study, an experimental approach was performed in the Polytechnic University of Bari, during the first days of March, in free running conditions. First, the results of questionnaires were compared according to the application of the Fanger model and the adaptive model; second, using a subjective scale, a complete analysis was performed on thermal preference in terms of acceptability, neutrality and preference, with particular focus on the influence of gender. The user possibility to control the indoor plant system produced a significant impact on the thermal sensation and the acceptability of the thermal environment. Gender was also demonstrated to greatly influence the thermal judgement of the thermal environment when an outdoor cold climate occurs. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

    2016-12-01

    This study examined subject-object asymmetry and developmental sequence in the second language (L2) acquisition of three types of wh-extraction, i.e., English headed relatives, headless relatives, and embedded wh-questions. Sixty-four L1 Korean learners of English completed an elicited imitation task and a grammaticality judgment task. The learners demonstrated a subject advantage in the headed RCs and headless RCs, but an object advantage in the embedded wh-questions, which suggests that they treat embedded wh-questions differently from headed relatives and headless relatives despite the similarities in surface forms. The learners further demonstrated the order of developing headless RCs followed by embedded wh-questions, and subsequently headed RCs, which supports the primacy of headless relatives as a simple nominal in L2 development.

    2017-01-01

    This study sought to examine predictors of subjective/objective sleep discrepancy in poor sleepers. Forty-two individuals with insomnia symptoms (mean age = 36.2 years, 81% female) were recruited to take part in a prospective study which combined seven days of actigraphy with daily assessment of sleep perceptions, self-reported arousal, sleep effort, and mood upon awakening. A high level of intra-individual variability in measures of sleep discrepancy was observed. Multilevel modelling revealed that higher levels of pre-sleep cognitive activity and lower mood upon awakening were significantly and independently predictive of the underestimation of total sleep time. Greater levels of sleep effort predicted overestimation of sleep onset latency. These results indicate that psychophysiological variables are related to subjective/objective sleep discrepancy and may be important therapeutic targets in the management of insomnia. PMID:28282912

    2007-01-01

    The role played by key community representatives in the evaluation of community alcohol projects differs according to the evaluation paradigm adopted. In evaluations that adopt a positivist, experimental design they are cast in the role of independent informants. In post-positivist evaluations they are seen as having an interest in the evaluation and accordingly are considered active stakeholders. However, the degree to which stakeholders can be actively engaged in an evaluation varies considerably along a number of dimensions. Four dimensions of the stakeholder role--stakeholder inclusiveness, participation mode, participation frequency, and evaluation role--are examined in the context of eight evaluation theories. This is integrated into a model that links these dimensions to an object-subject continuum of stakeholder involvement. The model facilitates systematic consideration of these dimensions and will assist evaluators in achieving their desired balance of subjective insight and objective fact.

    The aims of the present study were: (a) to examine the agreement between subjective (assessed via the International Physical Activity Questionnaire; IPAQ) and objective (accelerometry; GT3X) physical activity (PA) levels in patients with rheumatoid arthritis (RA), and (b) to evaluate the associations of RA patients' subjective and objective PA to their scores on the maximal oxygen uptake test (VO2max). The participants wore the GT3X for seven days before completing the IPAQ and VO2max test. The Bland-Altman plot was used to illustrate the agreement between the objective and subjective PA data, and the Wilcoxon test was employed to examine the differences. The association between the PA measurement and VO2max test was examined via the correlations and the magnitude was presented by the Steiger's Z value. Sixty-eight RA patients (age=55±13 years, body mass index: 27.8±5.4 kg/m2, median of disease duration=5 (2-8) yrs) were recruited. Smaller differences between the subjective and objective measures were found when PA was assessed at the moderate level. Wilcoxon tests revealed that patients reported less time spent engaged in sedentary behaviours (Z=-6.80, P<0.01) and light PA (Z=-6.89, P<0.01) and more moderate PA (Z=-6.26, P<0.01) than was objectively indicated. Significant positive correlations were revealed between VO2max with all PA levels derived from accelerometry (light PA rho=.35, P<.01; moderate PA rho=.34, P=.01; moderate and vigorous PA, (MVPA) rho=.33, P=.01), and a negative association to sedentary time (ST) emerged (rho=-.27, P=.04). IPAQ-reported moderate PA and MVPA positively correlated with maxV02 (rho=.25, P=.01, rho=.27, P=.01, respectively). Differences between the magnitude of correlations between the IPAQ-VO2 max and GT3X-VO2 max were only significant for ST (Z=3.43, P<.01). Via responses to the IPAQ, RA patients reported that they were less sedentary and engaged in more higher intensity PA than what was objectively assessed. Accelerometry

  9. A Critical Look at the Subjective and Objective Purposes of Contract in Aharon Barak’s Theory of Interpretation

    2016-12-01

    Full Text Available Sometimes parties to a contract agree on the wording of the contract, but disagree about its meaning. In such cases, the goal of purposive interpretation is to identify a legal meaning, within the limits of the language actually used, which best achieves the purpose of the contract in question. This paper presents the main features of Justice Aharon Barak’s theory of purposive interpretation of contracts, and examines his notions of subjective and objective purposes. Barak’s theory demands, at some point along the process of interpretation, that the judge determine the actual joint intent of the parties, as it was at the time of their entering into the contract, and in the situation where the parties themselves disagree over it. This requires a posterior inquiry into the true state of mind of other persons. The past intentions of others are regarded as historical-subjective psycho-biological facts. The author questions what goes on behind this subjective rhetoric, starting from the presumption that the inner reality of another person’s will, i.e. their past or present intentions, cannot be learned as a physical reality, but only as a socially constructed fact. Furthermore, the author examines the seemingly unwanted merging of Barak’s subjective purpose of contract with his objective purposes of contract at the lower levels of abstraction.

    Transcranial magnetic stimulation (TMS) can be used to mask visual stimuli, disrupting visual task performance or preventing visual awareness. While TMS masking studies generally fix stimulation intensity, we hypothesized that varying the intensity of TMS pulses in a masking paradigm might inform several ongoing debates concerning TMS disruption of vision as measured subjectively versus objectively, and pre-stimulus (forward) versus post-stimulus (backward) TMS masking. We here show that both pre-stimulus TMS pulses and post-stimulus TMS pulses could strongly mask visual stimuli. We found no dissociations between TMS effects on the subjective and objective measures of vision for any masking window or intensity, ruling out the option that TMS intensity levels determine whether dissociations between subjective and objective vision are obtained. For the post-stimulus time window particularly, we suggest that these data provide new constraints for (e.g. recurrent) models of vision and visual awareness. Finally, our data are in line with the idea that pre-stimulus masking operates differently from conventional post-stimulus masking.

    A small but growing body of work has studied the role of cognitive skills in predicting response to integrated programs of rehabilitation in schizophrenia. No studies however, have directly compared the roles and interrelationships of cognition, social cognition and other disease factors in predicting improvements in the separate domains of objective quality-of-life (QOL) and subjective satisfaction with life (SWL) in response to rehabilitation in schizophrenia,. Forty-four outpatients with schizophrenia were administered measures of cognition, social cognition, and symptoms at entry to a psychosocial and cognitive rehabilitation program. Change in objective QOL and subjective SWL before and after treatment were measured as outcome variables. Cognitive measures of verbal memory and social cognitive measures of facial affect recognition were linked to improvements in objective QOL, while verbal memory and crystallized verbal skill was linked to improvements in SWL. Facial affect recognition partially mediated the relationship between verbal memory and improvements in objective QOL. The implications of these findings for understanding interrelationships between cognition and social cognition and their role in predicting change in different domains of outcome as a function of behavioral treatment are discussed.

    Full Text Available BACKGROUND: The diagnosis of lymphedema can be obtained objectively by measurement methods, and also by subjective methods, based on the patient's complaint. OBJECTIVE: To evaluate inter-rater reliability of objective and subjective criteria used for diagnosis of lymphedema and to propose a lymphedema cut-off for differences in volume between affected and control limbs. METHODS: We studied 84 patients who had undergone lymphadenectomy for treatment of cutaneous melanoma. Physical measures were obtained by manual perimetry (MP. The subjective criteria analyzed were clinical diagnosis of lymphedema in patients' medical records and self-report of feelings of heaviness and/or increase in volume in the affected limb. RESULTS: For upper limbs, the subjective criteria clinical observation (k 0.754, P<0.001 and heaviness and swelling (k 0.689, P<0.001 both exhibited strong agreement with MP results and there was moderate agreement between MP results and swelling (k 0.483 P<0.001, heaviness (k 0.576, P<0.001 and heaviness or swelling (k 0.412, P=0.001. For lower limbs there was moderate agreement between MP results and clinical observation (k 0.423, P=0.003 and regular agreement between MP and self-report of swelling (k 0.383, P=0.003. Cut-off values for diagnosing lymphedema were defined as a 9.7% difference between an affected upper limb and control upper limb and a 5.7% difference between lower limbs. CONCLUSION: Manual perimetry, medical criteria, and self-report of heaviness and/or swelling exhibited better agreement for upper limbs than for lower limbs for diagnosis of lymphedema.

  13. Fatigue in Emergency Services Operations: Assessment of the Optimal Objective and Subjective Measures Using a Simulated Wildfire Deployment

    2016-01-01

    Full Text Available Under controlled laboratory conditions, neurobehavioral assays such as the Psychomotor Vigilance Task (PVT are sensitive to increasing levels of fatigue, and in general, tend to correlate with subjective ratings. However, laboratory studies specifically curtail physical activity, potentially limiting the applicability of such findings to field settings that involve physical work. In addition, laboratory studies typically involve healthy young male participants that are not always representative of a typical working population. In order to determine whether these findings extend to field-like conditions, we put 88 Australian volunteer firefighters through a multi-day firefighting simulation. Participants were required to perform real-world physical and cognitive tasks under conditions of elevated temperature and moderate sleep restriction. We aimed to examine changes in fatigue in an effort to determine the optimum objective and subjective measures. Objective and subjective tests were sensitive to fatigue outside laboratory conditions. The PVT was the most sensitive assay of objective fatigue, with the Samn-Perelli fatigue scale the most sensitive of the subjective measures. The Samn-Perilli fatigue scale correlated best with PVT performance, but explained a small amount of variance. Although the Samn-Perelli scale can be easily administered in the field, the wide range of individual variance limits its efficacy as a once-off assessment tool. Rather, fatigue measures should be applied as a component of a broader fatigue risk management system. Findings provide firefighting agencies, and other occupations involving physical work, guidance as to the most sensitive and specific measures for assessing fatigue in their personnel.

    The goal of this study is to investigate associations between subjective memory complaint and objective cognitive performance in older people with previous major depression–a high-risk sample for cognitive impairment and later dementia. A cross-sectional study was carried out in people aged 60 or over with previous major depression but not fulfilling current major depression criteria according to DSM-IV-TR. People with dementia or Mini-Mental State Examination score less than 17 were excluded. Subjective memory complaint was defined on the basis of a score ≧4 on the subscale of Geriatric Mental State schedule, a maximum score of 8. Older people aged equal or over 60 without any psychiatric diagnosis were enrolled as healthy controls. Cognitive function was evaluated using a series of cognitive tests assessing verbal memory, attention/speed, visuospatial function, verbal fluency, and cognitive flexibility in all participants. One hundred and thirteen older people with previous major depression and forty-six healthy controls were enrolled. Subjective memory complaint was present in more than half of the participants with depression history (55.8%). Among those with major depression history, subjective memory complaint was associated with lower total immediate recall and delayed verbal recall scores after adjustment. The associations between subjective memory complaint and worse memory performance were stronger in participants with lower depressive symptoms (Hamilton Depression Rating Scale score<7). The results suggest subjective memory complaint may be a valid appraisal of memory performance in older people with previous major depression and consideration should be given to more proactive assessment and follow-up in these clinical samples.

    Full Text Available A total of 546 students participated in the Tier 1 Program of the P.A.T.H.S. Project responded to the Chinese Positive Youth Development Scale (CPYDS at pretest and posttest and the Subjective Outcome Scale (SOS at posttest. Result showed that the SOS was internally consistent. The SOS total scores were significantly related to measures of global satisfaction and the participants' degree of sharing with others, thus giving support to its construct validity. Factor analysis revealed that there were three dimensions of the scale and the related subscales were significantly correlated among themselves. Based on the significant relationships between the SOS measures of perceived program effectiveness and posttest CPYDS scores as well as changes in CPYDS scores, the present study revealed the convergence of subjective outcome evaluation findings and objective outcome evaluation findings in the P.A.T.H.S. Project.

    A huge research literature, across the behavioral and social sciences, uses information on individuals' subjective well-being. These are responses to questions--asked by survey interviewers or medical personnel--such as, "How happy do you feel on a scale from 1 to 4?" Yet there is little scientific evidence that such data are meaningful. This study examines a 2005-2008 Behavioral Risk Factor Surveillance System random sample of 1.3 million U.S. citizens. Life satisfaction in each U.S. state is measured. Across America, people's answers trace out the same pattern of quality of life as previously estimated, from solely nonsubjective data, in one branch of economics (so-called "compensating differentials" neoclassical theory, originally from Adam Smith). There is a state-by-state match (r = 0.6, P < 0.001) between subjective and objective well-being. This result has some potential to help to unify disciplines.

  17. Evaluating auditory stream segregation of SAM tone sequences by subjective and objective psychoacoustical tasks, and brain activity

    Full Text Available Auditory stream segregation refers to a segregated percept of signal streams with different acoustic features. Different approaches have been pursued in studies of stream segregation. In psychoacoustics, stream segregation has mostly been investigated with a subjective task asking the subjects to report their percept. Few studies have applied an objective task in which stream segregation is evaluated indirectly by determining thresholds for a percept that depends on whether auditory streams are segregated or not. Furthermore, both perceptual measures and physiological measures of brain activity have been employed but only little is known about their relation. How the results from different tasks and measures are related is evaluated in the present study using examples relying on the ABA- stimulation paradigm that apply the same stimuli. We presented A and B signals that were sinusoidally amplitude modulated (SAM tones providing purely temporal, spectral or both types of cues to evaluate perceptual stream segregation and its physiological correlate. Which types of cues are most prominent was determined by the choice of carrier and modulation frequencies (fmod of the signals. In the subjective task subjects reported their percept and in the objective task we measured their sensitivity for detecting time-shifts of B signals in an ABA- sequence. As a further measure of processes underlying stream segregation we employed functional magnetic resonance imaging (fMRI. SAM tone parameters were chosen to evoke an integrated (1-stream, a segregated (2-stream or an ambiguous percept by adjusting the fmod difference between A and B tones (∆fmod. The results of both psychoacoustical tasks are significantly correlated. BOLD responses in fMRI depend on ∆fmod between A and B SAM tones. The effect of ∆fmod, however, differs between auditory cortex and frontal regions suggesting differences in representation related to the degree of perceptual ambiguity of

    This study aimed to objectively evaluate the radiopacity of different dental composites and their subjective influence on diagnosing secondary caries-like lesions and how these results correlate. For objective analysis, three resin specimens (1 mm thick, with a 4-mm internal diameter) were made with four composites: 1) Charisma; 2) Filtek Z250; 3) Prisma AP.H; and 4) Glacier. Three human teeth were selected and then mesio-distally sectioned (1 mm thick) to make the dental specimens. An aluminum (Al) wedge (12 steps, 1 mm thick, 99.8% purity) was used as an internal standard to calculate the radiopacity. For subjective analysis, 20 human teeth were selected and then prepared with a mesio-occluso-distal (MOD) inlay cavity, with half the teeth receiving a round cavity to simulate the carious lesion. The MOD was restored using the composites at four different times. Standardized radiographs were acquired and then digitized (300 dpi and eight-bit TIFF) for both analyses. A histogram objectively measured the pixel intensity values of the images, which were converted into millimeters of Al using linear regressions. Eight observers subjectively evaluated the images using a five-point rating scale to diagnose the caries. The data were statistically analyzed using the Student t-test, the Kappa test, diagnostic testing, and the Pearson correlation coefficient (α=0.05). All materials showed radiopacity values compatible with dental tissues (p>0.05); Glacier was similar to dentin and Prisma AP.H was similar to enamel, while the remaining materials showed a middle radiopacity. Prisma AP.H and Glacier differed (pdental composite is closer to the dentin image and produces similar attenuation to X-rays than does dentin.

    The aim of the present study was to examine the effect of match standard and referee experience on the objective and subjective workload of referees during English Premier League and Football League soccer matches. We also examined the relationship between heart rate (HR) and ratings of perceived exertion (RPE) for assessing match intensity in soccer referees. Heart rate responses were recorded using short-range telemetry and RPE scores were collected using a 10-point scale. Analysis revealed a significant relationship between mean match HR and match RPE scores (r=0.485, pReferee experience had no effect on match HR and RPE responses to Premier League and Football League matches. The results of the present study demonstrate the validity of using HR and RPE as a measure of global match intensity in soccer referees. Referee experience had no effect on the referees' objective and subjective match workload assessments, whereas match intensity was correlated to competition standard. These findings have implications for fitness preparation and evaluation in soccer referees. When progressing to a higher level of competition, referees should ensure that appropriate levels of fitness are developed in order to enable them to cope with an increase in physical match demands.

    The purpose of the present study is to investigate the relationships among subjective and objective quality of life (QOL), and levels of life skills, and their clinical determinants in outpatients with schizophrenia by using schizophrenia disease-specific QOL measures. Data collected from 64 outpatients were analyzed. Subjective QOL was measured with the Schizophrenia Quality of Life Scale (SQLS) and objective QOL with the Quality of Life Scale (QLS). Patients' family members completed the Life Skills Profile (LSP). Clinical symptoms were also assessed with several scales including the Brief Psychiatric Rating Scale (BPRS) and the Calgary Depression Scale for Schizophrenia (CDSS). Only the motivation/energy scale, but not the other scales of the SQLS, correlated with the QLS. The LSP rated by the family showed significant correlations with both the SQLS and the QLS. The CDSS score predicted each scale of the SQLS, and the BPRS negative symptoms score predicted the QLS. The LSP was predicted by the BPRS negative symptoms score and the CDSS score independently. These results indicate that the patient's QOL could be predicted by the life skills measured by a family member and suggest that active treatment for depressive and negative symptoms might be recommended to improve the patient's QOL and life skills.

    Background Open-door laminoplasty is widely used in the treatment of cervical spondylotic myelopathy (CSM).This study aimed to investigate the profiles of and correlation between objective and subjective short-term outcome assessments after open-door laminoplasty for CSM.Methods We retrospectively analyzed surgical outcomes in 129 consecutive CSM patients who underwent open-door laminoplasty in Peking University Third Hospital from February 2008 to November 2011.Both objective and subjective assessments were evaluated before surgery,3 months after surgery,and 1 year after surgery.We then analyzed the profiles of and correlation between objective and subjective short-term outcomes.Results The Modified Japanese Orthopaedic Association (mJOA) score was significantly improved at 3 months (P<0.01) and 1 year (P<0.01) after surgery.Bivariate Logistic regression showed that sensory improvement contributed more to the recovery rate than motor function improvement at 3 months after surgery,while motor function contributed more to the recovery rate at 1 year after surgery.On the subjective assessment (the short form (SF)-36),there was no significant improvement at 3 months after surgery (P>0.05),while physical function (PF),role-physical (RP),and social function (SF) were notably improved at 1 year after surgery (P<O.01).Improved mJOA score correlated with improvements in PF,RP,bodily pain,general health (GH),vitality (VT),and SF (P<O.05) at 3 months after surgery; PF,GH,VT,and SF were associated with improved mJOA scores at 1 year after surgery.Conclusions Patients benefit from surgery by postoperative restitution of neurological function with early recovery of sensory function,followed by a gradual transition to motor function improvement.At the early stage of recovery,improvement in the mJOA score essentially correlated with improvements in the physical domains of the SF-36,while at the later stage,mJOA score improvement was associated with improvements in both

    Background The true proliferation degree of bum and operation scars during their maturation was poorly defined. The objective of this study was to provide a quantitative evaluation of the proliferation degree of deep-partial thickness bum and surgical suture wound scars after wound healing and the accuracy of subjective judgment of scar types. Methods A total of 423 patients in the burn group and 667 patients in the suture wound group were enrolled in this study. Objective scar measurement (by negative-positive moulage) was carried out at 3, 6 and 12 months after wound healing in 1090 patients from different regions in China. The KruskaI-Wallis H test and chi-square test were used in the statistical analysis. Results The median degrees of scar proliferation were 0.03 cm at 3 months, 0.03 cm at 6 months and 0 cm at 12 months in the burn group and 0.05 cm, 0.04 cm and 0.04 cm respectively in the suture wound group. At 3 and 6 months post wound healing, there was no significant difference in scar proliferation between the groups (P>0.01). After 1 year, burn scars displayed evidence of atrophy (P<0.01). Although the degree of scar proliferation differed among the four scar types (P<0.01), the ranges of scar height in the four scar types largely overlapped when judged in a subjective manner, especially in proliferation and superficial scars. Conclusions Scar atrophy occurs after one year in burns, but not in the surgical suture wound group. It is important to take anti-scar therapy for surgical wounds as well as burn wounds. The various scar types could not be judged precisely in a subjective manner.

    The aim of this retrospective cohort study is to investigate the association between different subjective and objective assessments of ankle function in a population of athletes with or without functional ankle instability (FAI). 29 athletes with a history of ankle spraining were divided into two groups according to their ankle status: 16 with FAI (initial ankle sprain with residual functional instability) (age 24.6 ± 3.1 years), and 13 COPERS (initial ankle sprain without residual instability) (age 25.3 ± 4.4 years). The assessment of each individual's ankle function was based on three approaches: The "functional-ankle-ability-measure" (FAAM) assessing subjective ankle functionality, measures of sensorimotor control as objective functional measurements and MRI-based T2-mapping as a quantitative marker of compositional joint status. Pearson's product-moment-correlation coefficient, student's t-test and analysis-of-variance were used for statistical analysis. Significant group differences existed for subjective ankle function (FAAM, p = 0.04) and MRI-data mainly in the medial compartment of the ankle joint (p ≤ 0.05). We found unique associations between T2-mapping results and sensorimotor scores in the COPER (r = -0.756-0.849), and "FAI"-group (r = 0.630-0.657). The location and magnitude differed between groups. No correlations existed between these measures and the FAAM. This exploratory study provides preliminary evidence for potential interrelations between various diagnostic measures of ankle function and structure in individuals with and without FAI. We found associations between MRI-results and selected measures of sensorimotor control, indicating a potential link between loss of ankle function and early joint degeneration. Despite these interrelations, each of the different assessment options appears to contain unique information on ankle functionality important in a clinical assessment. © 2015 Orthopaedic Research Society.

  4. It felt fluent, and I liked it: subjective feeling of fluency rather than objective fluency determines liking.

    According to the processing-fluency explanation of aesthetics, more fluently processed stimuli are preferred (R. Reber, N. Schwarz, & P. Winkielman, 2004, Processing fluency and aesthetic pleasure: Is beauty in the perceiver's processing experience? Personality and Social Psychology Review, Vol. 8, pp. 364-382.). In this view, the subjective feeling of ease of processing is considered important, but this has not been directly tested in perceptual processing. In two experiments, we therefore objectively manipulated fluency (ease of processing) with subliminal perceptual priming (Study 1) and variations in presentation durations (Study 2). We assessed the impact of objective fluency on feelings of fluency and liking, as well as their interdependence. In line with the processing-fluency account, we found that objectively more fluent images were indeed judged as more fluent and were also liked more. Moreover, differences in liking were even stronger when data were analyzed according to felt fluency. These findings demonstrate that perceptual fluency is not only explicitly felt, it can also be reported and is an important determinant of liking.

    Utilizing polysomnography (PSG) and psychometry, objective and subjective sleep and awakening quality was investigated in 11 drug-free patients (five females, six males) aged 35-75 years (mean age 54.1 +/- 11.4) suffering from nonorganic insomnia (F 51.0) related to a depressive episode (F 32) or recurrent depressive disorder (F 33). as compared with 11 age- and sex-matched normal controls (five females, six males) aged 36-75 years (mean age 53.0 +/- 13.5). PSG demonstrated decreased sleep efficiency, total sleep time (TST), total sleep period (TSP) and sleep stage S2, as well as increased wakefulness during TSP, early morning awakening, sleep latency to S1, S2, S3 and sleep stage S1 in depressed patients. Subjective sleep quality and the total score of the Self-Assessment of Sleep and Awakening Quality Scale (SSA) were deteriorated as were morning and evening well being, drive, mood and fine motor activity right. Evening and morning blood pressure, the O2 desaturation index and periodic leg movement (PLM) index were increased. In a subsequent acute, placebo-controlled cross-over design study, the acute effects of 100 mg of trazodone, a serotonin reuptake inhibitor with a sedative action due to 5-HT2 and alpha1 receptor blockade, were investigated in the patients. As compared with placebo, trazodone induced an increase in sleep efficiency (primary target variable), TST, TSP and SWS (S3 + S4), as well as a decrease in wakefulness during the TSP, early morning awakening and S2. There was no change in rapid eye movement (REM) sleep with the exception of an increase in the REM duration in minutes. Trazodone also caused an improvement in subjective sleep quality, affectivity, numerical memory and somatic complaints. All respiratory variables remained within normal limits. Critical flicker frequency and moming diastolic blood pressure were decreased. The present study demonstrated that depression induced significant changes in objective and subjective sleep and awakening

    Full Text Available Perception of natural visual scenes activates several functional areas in the human brain, including the Parahippocampal Place Area (PPA, Retrosplenial Complex (RSC, and the Occipital Place Area (OPA. It is currently unclear what specific scene-related features are represented in these areas. Previous studies have suggested that PPA, RSC, and/or OPA might represent at least three qualitatively different classes of features: (1 2D features related to Fourier power; (2 3D spatial features such as the distance to objects in a scene; or (3 abstract features such as the categories of objects in a scene. To determine which of these hypotheses best describes the visual representation in scene-selective areas, we applied voxel-wise modeling (VM to BOLD fMRI responses elicited by a set of 1,386 images of natural scenes. VM provides an efficient method for testing competing hypotheses by comparing predictions of brain activity based on encoding models that instantiate each hypothesis. Here we evaluated three different encoding models that instantiate each of the three hypotheses listed above. We used linear regression to fit each encoding model to the fMRI data recorded from each voxel, and we evaluated each fit model by estimating the amount of variance it predicted in a withheld portion of the data set. We found that voxel-wise models based on Fourier power or the subjective distance to objects in each scene predicted much of the variance predicted by a model based on object categories. Furthermore, the response variance explained by these three models is largely shared, and the individual models explain little unique variance in responses. Based on an evaluation of previous studies and the data we present here, we conclude that there is currently no good basis to favor any one of the three alternative hypotheses about visual representation in scene-selective areas. We offer suggestions for further studies that may help resolve this issue.

    A growing literature shows prominent sex effects for risk for post-traumatic stress disorder and associated medical comorbid burden. Previous research indicates that post-traumatic stress disorder is associated with reduced slow wave sleep, which may have implications for overall health, and abnormalities in rapid eye movement sleep, which have been implicated in specific post-traumatic stress disorder symptoms, but most research has been conducted in male subjects. We therefore sought to compare objective measures of sleep in male and female post-traumatic stress disorder subjects with age- and sex-matched control subjects. We used a cross-sectional, 2 × 2 design (post-traumatic stress disorder/control × female/male) involving83 medically healthy, non-medicated adults aged 19-39 years in the inpatient sleep laboratory. Visual electroencephalographic analysis demonstrated that post-traumatic stress disorder was associated with lower slow wave sleep duration (F(3,82)  = 7.63, P = 0.007) and slow wave sleep percentage (F(3,82)  = 6.11, P = 0.016). There was also a group × sex interaction effect for rapid eye movement sleep duration (F(3,82)  = 4.08, P = 0.047) and rapid eye movement sleep percentage (F(3,82)  = 4.30, P = 0.041), explained by greater rapid eye movement sleep in post-traumatic stress disorder females compared to control females, a difference not seen in male subjects. Quantitative electroencephalography analysis demonstrated that post-traumatic stress disorder was associated with lower energy in the delta spectrum (F(3,82)  = 6.79, P = 0.011) in non-rapid eye movement sleep. Slow wave sleep and delta findings were more pronounced in males. Removal of post-traumatic stress disorder subjects with comorbid major depressive disorder, who had greater post-traumatic stress disorder severity, strengthened delta effects but reduced rapid eye movement effects to non-significance. These findings support previous evidence that post

    Sleep quality is one of the key elements of the human health status. By observing sleep patterns we can gain information about personal wellbeing. Consumer electronic sleep analysis solutions are now available for use in long-term conditions. In this study we compare different measures for total sleep time and sleep quality. We analyzed visually long- term sleep data collected with actigraphy, sleep logs and ambient sensors to gain more reliable results and compared these results to each single method's output. Correlations of visually analyzed total sleep time between actigraphy total sleep time (correlation coefficient (r) = 0.662, p <0.01) and sleep log total sleep time (r = 0.787, p <0.01) were high. Also comparison between subjective and objective sleep quality was analyzed and small, but significant correlation was found (r = 0.270, p < 0.01).

    Full Text Available An inverted paper cup of 0.26 mm thickness was subjected to deformation under a freely falling steel ball at a velocity of 2.77 m/sec. The deformed features of the paper cup were measured. The dynamic loading event was simulated using piecewise linear plasticity material model in LSDYNA. Deformed shape of the paper cup in finite element model matched closely with experimental results with ignorable small discrepancies. The paper cup was able to absorb all the kinetic energy of the falling steel ball for the above mentioned falling speed and the ball did not bounce out of the cavity generated by the impact. In LSDYNA a similar size steel cup was also subjected to a freely falling ball with same speed and the energy absorbed was compared to the energy absorbed by the paper cup. It was found that under similar conditions a paper cup would undergo a significant progressive failure and absorb all the energy of the falling object.

    Governmental authorities of wealthy developed nations differ in their professed commitments and activity related to the provision of the prerequisites of health through public policy action. Part 1 of this article showed how nations identified as social democratic or liberal welfare states were those where such commitments are present. Nations identified as conservative or Latin welfare states were less likely to express such commitments. However, the political economy literature suggests that despite their expressed commitments to provision of the prerequisites of health, liberal welfare states fare rather poorly in implementing these commitments. The opposite is seen for conservative welfare states. Social democratic welfare states show both commitments and public policy consistent with this objective. Part 2 of this article documents the extent to which public policy activity that provides the prerequisites of health through public policy action differs among varying welfare state regimes. Despite extensive rhetoric concerning the prerequisites of health, nations identified as liberal welfare states do a rather poor job of meeting these goals and show evidence of adverse health outcomes. In contrast, social democratic welfare states fare better in providing such prerequisites--consistent with their rhetorical statements--with better health outcomes. Interestingly, conservative--and to a lesser extent Latin--nations fare well in providing the prerequisites of health despite their lack of explicit commitment to such concepts. Findings suggest that health promoters have to concern themselves with the broad strokes of public policymaking whether or not these policy activities are identified as health promotion activities.

    Extended exposure to hand-transmitted vibration from vibrating machine is associated with an increased occurrence of symptoms of occupational disease related to hand disorder. The present case study is to determine the prevalence and correlation of significant subjective as well as objective variables that induce to hand arm vibration syndrome (HAVS) among hand-held grass-cutting workers in Malaysia. Thus, recommendations are made for grass-cutting workers and grass maintenance service management based on findings. A cross sectional study using adopted subjective Hand Arm Vibration Exposure Risk Assessment (HAVERA) questionnaire from Vibration Injury Network on hand disorder signs and symptoms was distributed to a sample of one hundred and sixty eight male workers from grass and turf maintenance industry that use vibrating machine as part of their work. For objective measure, hand-transmitted vibration measurement was collected on site during operation by the following ISO 5349-1, 2001. Two groups were identified in this research comprising of high exposure group and low-moderate exposure group. Workers also gave information about their personal identification, social history, workers’ health, occupational history and machine safety inspection. There was positive HAVS symptoms relationship between the low-moderate exposure group and high exposure group among hand-held grass-cutting workers. The prevalence ratio (PR) was considered high for experiencing white colour change at fingers and fingers go numb which are 3.63 (1.41 to 9.39) and 4.24 (2.18 to 8.27), respectively. The estimated daily vibration exposure, A(8) differs between 2.1 to 20.7 ms-2 for right hand while 2.7 to 29.1 ms-2 for left hand. The subjects claimed that the feel of numbness at left hand is much stronger compared to right hand. The results suggest that HAVS is diagnosed in Malaysia especially in agriculture sector. The A(8) indicates that the exposure value is more than exposure limit value

    In the present article, the reorientation of a fourth-semester physiology course for pharmacy students is described. The motivation for the introduction of changes was to prepare the students to not only assimilate facts but to learn and understand how to integrate and apply them. The article considers how this reorganization was received by the students in both subjective and objective terms. Specifically, we investigate whether our changes resulted in both an enhanced learning experience and improved learning success. The following changes were introduced to the course: first, we integrated either experimental, computer-based teaching modules or case studies in five of the eight course units to give the students the opportunity to gain more hands-on experience; second, we organized regular meetings to enhance communication among the course tutors; and finally, we increased the pass mark for the entrance exam to the course from 50% to 60%. Student opinion was evaluated by means of a questionnaire that was distributed at the end of each course semester throughout the three-semester evaluation period (summer 2008, winter 2008/2009, and summer 2009). The students gave convincing positive feedback concerning the efficacy of the changes in both quantitative and qualitative terms. Moreover, their learning success improved significantly in objective terms as evidenced by enhanced final and State exam performance.

    Schulze Wolfgang

    2003-11-01

    Full Text Available Abstract Throughout spermatogenesis multiplication, maturation and differentiation of germ cells results in the formation of the male gamete. The understanding of spermatogenesis needs detailed informations about the organization of the germinal epithelium, the structure and function of different types of germ cells, endocrine and paracrine cells and mechanisms, intratesticular and extratesticular regulation of spermatogenesis. Normal germ cells must be discriminated from malformed, apoptotic and degenerating germ cells and tumor cells. Identification of the border line between normal and disturbed spermatogenesis substantiate the diagnosis of impaired male fertility. The profound knowledge of the complicate process of spermatogenesis and all cells or cell systems involved with is the prerequisite to develop concepts for therapy of male infertility or to handle germ cells in the management of assisted reproduction.

    Several previous studies have established the relationship between the effects of socioeconomic status or subjective social strata on life satisfaction. However, no previous study has examined the relationship between social class and life satisfaction in terms of a disparity between subjective and objective social status. To investigate the relationship between differences in subjective and objective social class and life satisfaction. Data from the Korean Longitudinal Study of Aging with 8252 participants aged 45 or older was used. Life satisfaction was measured by the question, "How satisfied are you with your quality of life?" The main independent variable was differences in objective (income and education) and subjective social class, which was classified according to nine categories (ranging from high-high to low-low). This association was investigated by linear mixed model due to two waves data nested within individuals. Lower social class (income, education, subjective social class) was associated with dissatisfaction. The impact of objective and subjective social class on life satisfaction varied according to the level of differences in objective and subjective social class. Namely, an individual's life satisfaction declined as objective social classes decreased at the same level of subjective social class (i.e., HH, MH, LH). In both dimensions of objective social class (education and income), an individual's life satisfaction declined as subjective social class decreased by one level (i.e., HH, HM, HL). Our findings indicated that social supports is needed to improve the life satisfaction among the population aged 45 or more with low social class. The government should place increased focus on policies that encourage not only the life satisfaction of the Korean elderly with low objective social class, but also subjective social class.

    The objectives of this study are to evaluate the impact on voice of both duration and intensity level of 2 hours of continuous oral reading. Voice modifications accompanying changes in intensity level during prolonged reading tasks are analyzed. Fifty normophonic women undergo two sessions of voice loading in which the required intensity level of voice varied between 60-65 dB(A) for the first session and 70-75 dB(A) for the second session. The effects of loading on objective data (average fundamental frequency [F0], jitter%, shimmer%, noise-to-harmonic ratio, maximum phonation time, lowest frequency [F-Low], highest frequency [F-High], frequency range [Range], lowest intensity [I-Low] level, and highest intensity level) and self-ratings (voice quality, phonation effort, vocal fatigue, and laryngeal discomfort) are assessed every 30 minutes during the loading tasks. Results indicate that average F0, F-Low, I-Low, maximum phonation time, feeling of phonation effort, vocal fatigue, and laryngeal discomfort increase during prolonged reading, whereas shimmer% and self-rating of voice quality decrease. Average F0, F-High, and Range are the only parameters influenced by the required intensity of vocal load; they are significantly higher in the 70- to 75-dB session compared with the 60- to 65-dB session. Concerning the subjective self-ratings, similar results for the four ratings used suggest that only one would suffice in future studies. These results confirm the importance of both duration and intensity level as loading factors, even if intensity level affects fewer variables than duration. Copyright © 2012 The Voice Foundation.

    Although sleep disturbances are commonly reported among children exposed to violence, objective evidence of such disturbances is rare. This longitudinal, home-based study assessed the effects of a known community- or family-violence incident on both actigraphy-derived and subjectively reported sleep outcomes of an ethnically mixed, urban sample of children aged 8-16 years. We hypothesized that increased event severity (child physical assault, witnessed homicide) would be associated with lower sleep duration and poorer sleep quality both at baseline and at 3-month follow-up. Covariate-adjusted analyses based on a generalized estimating equations approach showed that children physically assaulted during the event showed lower sleep duration and sleep efficiency and greater wake after sleep onset than those not physically assaulted. Physically assaulted children were more likely to have a later bedtime than non-assaulted children, but this difference decreased at 3 months. Children witnessing a homicide showed greater wake after sleep onset at baseline and reported greater sleep problems than those witnessing a non-homicide event, but these differences decreased at 3 months. They were also somewhat more likely to have greater nightly variation in sleep duration. Collectively, results suggest that violence exposure influences children's sleep, but that specific dimensions of sleep may exhibit different susceptibility to different characteristics of violence, especially over time.

    According to IEA report (2011), about 23% of the World's CO2 emissions result from transport and this is one of the few areas where emissions are still rapidly increasing. The use of private vehicles is one of the principle contributors to green house gas emissions from transport sector. Therefore this paper focuses on the shift to more sustainable and low carbon forms of transportation mode such as walking. Neighbourhood built environment attributes may influence walkability. For this study, the author used a modified version of the "Neighbourhood Environment Walkability Scale" to make comparison between respondents' perceptions regarding attributes of two neighborhoods of Putrajaya. The 21st Century really needs planners to use the Digital Earth Concept, to go from global to regional to national to very local issues, using integrated, advanced technologies such as earth observation, GIS, virtual reality, etc. For this research, two (2) neighborhoods of different densities (High and Low density) were selected. A sample total of 381(195 and 186) between 7 to 65 years old participants were selected For subjective measures we used 54 questions questionnaire survey where as for the objective measures we used desktop 9.3 version of Arc GIS soft ware. Our results shows that respondents who reside in high-walkable neighbourhood precinct 9 in Putrajaya rated factors such as residential density, land use mix, proximity to destination and street connectivity, consistently higher then did respondents of the low walkable neighbourhood precinct 8 in Putrajaya.

    In 2 studies, we found support for current sexual harassment jurisprudence. Currently, the courts use a 2-prong test to determine the viability of a sexual harassment claim: that the adverse treatment is sufficiently severe or pervasive to alter conditions of employment based on a protected class from the perspective of the individual complainant (subjective prong) and from the perspective of a reasonable person (objective prong). In Experiment 1, trained male undergraduate research assistants administered sequential objectifying gazes and comments to undergraduate female research participants. We found that the pervasive objectification delivered by multiple men (compared with 1 man) did not elicit more negative emotion or harm the experiencers' task performance, although it did lead them to make increased judgments of sexual harassment. In Experiment 2, observers (who viewed a recording of an experiencer's interactions with the male research assistants) and predictors (who read a protocol describing the facts of the interaction) anticipated the female targets would experience negative emotions, show impaired performance, as well as find more evidence in the interaction of sexual harassment. Observers' judgments mirrored those of the experiencers' while predictors' judgments demonstrated affective forecasting errors. Predictors were more likely to anticipate more negative emotion, worse performance, and greater likelihood of sexual harassment. Overall, these studies demonstrate the impact and importance of considering perceptions of sexual harassment from multiple perspectives and viewpoints. (PsycINFO Database Record

  3. The Tell-Tale Heart: heart rate fluctuations index objective and subjective events during a game of chess

    Full Text Available During a decision making process, the body changes. These somatic changes have been related to specific cognitive events and also have been postulated to assist decision making indexing possible outcomes of different options. We used chess to analyze heart rate (HR modulations on specific cognitive events. In a chess game, players have a limited time-budget to make about 40 moves (decisions that can be objectively evaluated and retrospectively assigned to specific subjectively perceived events, such as setting a goal and the process to reach a known goal. We show that HR signals events: it predicts the conception of a plan, the concrete analysis of variations or the likelihood to blunder by fluctuations before to the move, and it reflects reactions, such as a blunder made by the opponent, by fluctuations subsequent to the move. Our data demonstrate that even if HR constitutes a relatively broad marker integrating a myriad of physiological variables, its dynamic is rich enough to reveal relevant episodes of inner thought.

    The introduction of small-diameter implants has provided dentists the means of providing edentulous and partially edentulous patients with immediate functioning transitional prostheses while definitive restorations are being fabricated. The successful use of these small-diameter implants for temporary stabilization of prostheses has led many clinicians to explore the option of using them as a definitive alternative, especially as the technique requires minimal time and also is economical for the patients. To date, there has been no study with multiple patients looking at both the subjective and objective outcomes of these small-diameter implants. Twenty-seven edentulous patients were enrolled in this study, seven of them were smokers. One-hundred and eight small-diameter (2.0 mm, MDL) implants were surgically placed in 24 edentulous mandibles. All implants were immediately loaded. The patients filled out a screening questionnaire and four subsequent questionnaires to test their satisfaction with the altered prosthesis at 6, 12, 18 and 24 months. The survival of the implants was also noted. Smokers had an implant survival of 79%. Non-smokers had an implant survival of 100%. The results of the questionnaire indicated an overall satisfaction with the implant-supported prosthesis.

    Skill in reading long words is prerequisite to dyslexics' literacy. Instant recognition of printed symbols is easy for those readers with photographic memories, but dyslexics often fail to recognize visually many long words which are actually familiar to them auditorially. Scientific, automatic, multisensory procedures for dividing longer words into easily read syllables can enable students to translate visual symbols rapidly and thereby to read, write, or spell accurately words of any length.Over one thousand dyslexics, aged seven to fifteen, guided the interdisciplinary team at Texas Scottish Rite Hospital in Dallas to develop, observe results, and test specific structured, sequential steps in working out longer words. The ten-year study (1965-1975) in the Language Laboratory of the Hospital established the Alphabetic Phonics curriculum which is now used successfully, not only in remedial groups but in regular classes of any size or age, in public and private schools in 45 states and six foreign countries.The newly-established Aylett Royall Cox Institute in Dallas prepares teachers and Master Instructors to train both students and other teachers. Comparable Alphabetic Phonics Teacher Training Centers are already established in Houston and Lubbock, Texas, in Oklahoma City, and at Columbia University Teachers College in New York.

Baseline physical activity and sedentary behaviors were assessed among 46 overweight and obese community-dwelling adults (aged 18-70 years; BMI > 27 kg/m(2)) diagnosed with SZO/SA by DSM-IV-TR, with mild symptom severity (Positive and Negative Syndrome Scale score physical activity levels, measured using actigraphs, in WAIST were compared to a nationally representative sample of users (n = 46) and nonusers (n = 46) of mental health service (MHS) from the National Health and Nutrition Examination Survey (NHANES 2003-2004) matched by sex, BMI, and age. On average, adults with SZO/SA wore actigraphs more than 15 h/d for 7 days averaging 151,000 counts/d. The majority of monitoring time (81%) was classified as sedentary (approximately 13 h/d). Moderate/vigorous and light physical activity accounted for only 2% (19 min/d) and 17% (157 min/d) of monitoring time/d, respectively. Primary source of activity was household activities (409 ± 438 min/wk). Fifty-three percent reported walking for transportation or leisure. Adults with SZO/SA were significantly less active (176 min/d) and more sedentary (756 min/d) than NHANES users of MHS (293 and 640 min/d, respectively) and nonusers of MHS (338 and 552 min/d, respectively) (P physical activity; and significantly less active than NHANES users and nonusers of MHS. This sedentary lifestyle is significantly lower than those of other inactive US populations, is costly for the individual and community, and highlights the need for physical activity promotion and interventions in this high risk population. © Copyright 2015 Physicians Postgraduate Press, Inc.

    Full Text Available Background Dance is an extremely complicated sports discipline, which combines features of the “original” form of dance associated with the expression of self and one’s emotions while maintaining the qualities of a competitive sport. It is particularly important for the cooperation of a couple to develop a relationship during training so that the partners feel satisfaction from working with each other, but are also pleased with the results in the discipline in which they train. The aim of this study was to analyse the factors responsible for the satisfaction with cooperation in a couple, which included, among other things, the dance level, degree of involvement and responsibility of each partner for the development of the couple. Participants and procedure The study involved 30 dance couples aged 13-26 years (M = 16.48, SD = 2.16. Participants completed two questionnaires (Own Poll and the Dyadic Trust Scale [DTS] and provided demographic information in a quiet environment, usually at their education or training facilities. Results The results indicated the importance of their own and perceived partner involvement in the development of the couple for the satisfaction from the success in the sport. It is surprising, however, that the results reveal no association between dance experience and satisfaction of practising sport analysed in the study. Conclusions Satisfaction plays an important role in relationships of pair dancers. In dancing, satisfaction may derive from subjective rather than objective factors, mainly those related to the relationship in the couple.

    People with fibromyalgia experience a disagreement between patient-reported (i.e., subjective) and performance-based (i.e., objective) status. This study aimed to (i) corroborate the discordance between subjectively and objectively measured physical function and (ii) examine whether catastrophizing (worrying, pain magnifying, and helpless cognitions) and self-efficacy (believing capable to manage pain) are independently associated with this discordance. This population-based cross-sectional study included 405 women with fibromyalgia and 193 age-matched female controls. Participants completed the Pain Catastrophizing Scale, Chronic Pain Self-efficacy Scale, and physical functioning subscales of the Revised Fibromyalgia Impact Questionnaire and Short Form-36 (SF-36) health survey. Objective physical function was measured with the Senior Fitness Test battery. Subjective and objective physical functions were expressed as deviation from the general population in standard deviation (SD) units using means and SD of the control group. In fibromyalgia, subjective physical function was worse than objective physical function (p ability to do meaningful activities of daily living (i.e., restrictions) that people with fibromyalgia are actually able to. Therefore, catastrophizing should be assessed and potentially targeted when focusing on improving physical function in fibromyalgia. Implications for rehabilitation Rehabilitation should focus on physical exercise programs to help women with fibromyalgia to improve their reduced physical function. In rehabilitation settings, physical function of people with fibromyalgia should be evaluated by both subjective and objective assessments to fully understand physical functioning and to test the existence of discordance between both assessments. In case of a large discordance between subjective and objective physical function, a physical exercise program might be better complemented with cognitive management techniques to reduce

    2014-10-01

    Objective, subjective, and neighborhood socioeconomic status (SES) are associated with perceived health, morbidity, and mortality. We investigated whether perceived stress and health behaviors mediated the relation between the three types of SES and perceived health. Participants (N = 508) attending a public clinic completed a computerized survey assessing objective SES (income, education, employment); health behaviors; perceived stress; and perceived health. They also indicated their social standing relative to others (subjective SES) and provided their current address to determine neighborhood SES. In a structural equation model including all three SES types, lower objective and subjective SES were related to poorer perceived health. When mediators were included in the model, there were significant indirect effects of (a) SES on health through stress and (b) SES on health through stress and health-compromising behaviors. Interventions to reduce the impact of stressors could improve the health of socioeconomically disadvantaged individuals.

    The main purpose of this study was to compare the effect of the 2 minimally invasive surgical techniques for treating axillary hyperhidrosis: superficial tumescent suction curettage and curettage only. A total of 22 patients diagnosed with axillary hyperhidrosis received one type of treatment at each side, randomized. Examinations were performed pre-operatively and at 3, 6 and 12 months following treatment. Sweating was measured by gravimetry and a new skin conductance method. Subjective rating of sweating was assessed by a visual analogue scale. Skin conductance was recorded during a stress-test including acoustic, mental and physical stressors. Five patients withdrew or did not meet for any follow-up examination, giving 17 subjects in total for data analysis. Significant reduction in sweating after surgery lasting at least 12 months was found based on skin conductance, gravimetry and visual analogue scale scoring. Comparison between types of treatment revealed a significantly better effect of tumescent suction curettage than curettage only.

    Sensitization statements were read to two groups of normal subjects to determine whether quantifiable thresholds for pressure, electrical, or tactile stimuli could be altered. Significant reductions in perception thresholds were observed for pressure and digital pulsed stimulation, but not for stimulation to the discomfort threshold, or two point discrimination. These data seem to suggest that increased sensitization is related to the ease of stimulus applications and the comparative simplicity of sensory processing.

    Evidence shows the positive influence of moderate and vigorous physical activity (MVPA) and negative influence of sedentary time on health and academic achievement. Although schools can significantly contribute to overall physical activity, little is known about MVPA and sedentary behaviour in different school subjects in different grades. Physical activity of 646 students from 18 schools (94 classes) and from three school stages (grades 1-9, aged 7-16) was measured with accelerometry for 5 school days. Time and proportion of MVPA and sedentary time, also average sedentary bout length was calculated for native language (Estonian), mathematics, science, foreign language, music and crafts lessons. A total of 6363 lessons were measured, with lesson duration of 45 min. The average lesson time MVPA remained below 2.2 min in all school stages and in all subjects. Students in grades 4-6 had greatest decline in the proportion of lesson time MVPA in science (β = -1.9, 95%CI -3.1- -0.6) and music (-1.2, -2.1- -0.4) and in grades 7-9 in music (-1.7, -3.1- -0.3) lessons compared to grades 1-3. In grades 1-3 students spent on average 76% of lesson time (34.0 ± 7.0 min) as sedentary, whereas in grades 7-9 the average proportion of sedentary time was 87% (38.9 ± 5.7 min). An average sedentary bout length increased from 13 min in grades 1-3 to 20 min in grades 7-9. An increase in sedentary bout length from grades 1-3 compared to grades 7-9 was present in most subjects, except crafts, with smallest increase in foreign language (6 min, 3.5-8.9) and greatest in music lessons (16.6 min, 11.9-21.3). Lessons with prolonged sedentary bouts formed a maximum 36% of all lessons in grades 1-3 and 73% in grades 7-9. The long sedentary time, bout length and low MVPA in most subjects were unfavourable in respect of both health and academic achievement. Significantly increasing sedentary time and sedentary bout length in older school stages highlights the need for

    Huber, Christian G; Huber, Johannes

    2009-07-01

    Whereas ethical considerations on imaging techniques and interpretations of neuroimaging results flourish, there is not much work on their preconditions. In this paper, therefore, we discuss epistemological considerations on neuroimaging and their implications for neuroethics. Neuroimaging uses indirect methods to generate data about surrogate parameters for mental processes, and there are many determinants influencing the results, including current hypotheses and the state of knowledge. This leads to an interdependence between hypotheses and data. Additionally, different levels of description are involved, especially when experiments are designed to answer questions pertaining to broad concepts like the self, empathy or moral intentions. Interdisciplinary theoretical frameworks are needed to integrate findings from the life sciences and the humanities and to translate between them. While these epistemological issues are not specific for neuroimaging, there are some reasons why they are of special importance in this context: Due to their inferential proximity, 'neuro-images' seem to be self-evident, suggesting directness of observation and objectivity. This has to be critically discussed to prevent overinterpretation. Additionally, there is a high level of attention to neuroimaging, leading to a high frequency of presentation of neuroimaging data and making the critical examination of their epistemological properties even more pressing. Epistemological considerations are an important prerequisite for neuroethics. The presentation and communication of the results of neuroimaging studies, the potential generation of new phenomena and new 'dysfunctions' through neuroimaging, and the influence on central concepts at the foundations of ethics will be important future topics for this discipline.

    2016-01-01

    There are concerns about the meaning of SRH and the factors individuals consider. To illustrate how SRH is contextualized, we examine how the obesity-SRH association varies across age, periods, and cohorts. We decompose SRH into subjective and objective components and used a mechanism-based APC model approach with four decades (1970s-2000s) and five birth cohorts of NHANES data (N=26,184). Obese adults rate their health more negatively than non-obese when using overall SRH with little variation by age, period, or cohort. However, when we decomposed SRH into objective and subjective components, the obesity gap widened with increasing age in objective SRH, but narrowed in subjective SRH. Additionally, the gap narrowed for more recently-born cohorts for objective SRH, but widened for subjective SRH. The results provide indirect evidence that the relationship between obesity and SRH is socially patterned according to exposure to information about obesity and the availability of resources to manage it.

    Subjectively and objectively assess stress urinary incontinence (SUI) symptoms before and after topical oestrogen therapy. A prospective study was performed in 3 centres in South-Africa, Australia and the Netherlands. Postmenopausal women with SUI were treated with topical oestriol cream for 6 weeks. The primary subjective outcome was the Patient's Global Impression of Improvement (PGI-I) scale. The primary objective outcome was vaginal pH. Secondary subjective outcomes were: the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form, the Incontinence Impact Questionnaire, the Urogenital Distress Inventory (UDI-6) and the most bothersome symptom approach. Secondary objective outcome was the erect cough pad test. Compliance was scored. A total of 68 women were enrolled. Half of the participants reported improvement on the PGI-I scale after treatment. Vaginal pH was significantly lower after treatment (median 5.3 (interquartile range (IQR) 4.5-6.0) vs. 5.0 (4.4-5.4), p = 0.002). Improvement on the UDI stress domain was observed (p = 0.01). No statistically significant differences were found in the other subjective outcomes. Baseline and repeat cough pad tests demonstrated a wide variation with no significant difference. Compliance was high (median 100 (IQR 83-100%)). Topical oestriol cream during 6 weeks improved quality of life and vaginal pH but no other objective measures of incontinence. © 2016 The Author(s) Published by S. Karger AG, Basel.

    The aim of the study was to explore the relationships between subjective or objective symptoms and mortality in schizophrenia. 310 subjects meeting the ICD-10 criteria for schizophrenia were included in the study between 1998 and 2000. At the initial assessment the following variables were respectively assessed to evaluate subjective and objective symptoms: the Frankfurt Complaints Questionnaire (FCQ) and the Positive and Negative Syndrome Scale (PANSS). In May 2008, information about the subjects were collected in order to know if they are alive or not and if they are deceased to know the date and the causes of their death. Survival analysis was conducted using the Kaplan-Meier product-limit estimator and standardized mortality ratio (SMR) was calculated. A multivariate Cox regression was done to detect predictive factors associated with mortality. Absolute mortality rates were 10.01%, 4.46% and 5.42% for overall mortality, unnatural causes and natural causes, respectively. SMR for overall mortality was 4.73. Cox regression analyses showed that elevated scores of FCQ was significant predictor of deaths from unnatural causes. High levels of subjective symptoms, as rated by the FCQ were independent predictor of mortality by unnatural causes in schizophrenic subjects. There were several limitations: The causes of death were not determined by autopsy and secondly, the duration of the study could be insufficient to detect significant associations between clinical variables and mortality.

    Conclusion: The Perigee System gave a favorable result in both anatomical and subjective success rates with a low rate of mesh-related morbidities. The strength of the study reported here is its long-term follow up of a relatively large number of patients and the use of validated questionnaires. Limitations are that it is not a RCT; hence, selection and indication bias is unavoidable. The favorable outcome and low morbidities resulting from mesh use is from a single surgeon's perspective and may not be generalized to others.

    Introduction: Studies suggest that cardiac resynchronization therapy (CRT) can induce a decrease in brain natriuretic peptide (BNP) and systemic inflammation, which may be associated with CRT-response. However, the evidence is inconclusive. We examined levels of BNP and inflammatory markers from...... ventricular end systolic volume; subjective CRT-response was defined as an improvement of ⩾10 points in patient-reported health status assessed with the Kansas City Cardiomyopathy Questionnaire. Plasma BNP and markers of inflammation (CRP, IL-6, TNFα, sTNFr1 and sTNFr2) were measured at three time points......=27.31, pinflammation. This indicates that response to CRT...

    This study aims to answer the question of whether there is a difference between robotic virtual reality simulator performance assessment and validated human reviewers. Current surgical education relies heavily upon simulation. Several assessment tools are available to the trainee, including the actual robotic simulator assessment metrics and the Global Evaluative Assessment of Robotic Skills (GEARS) metrics, both of which have been independently validated. GEARS is a rating scale through which human evaluators can score trainees' performances on six domains: depth perception, bimanual dexterity, efficiency, force sensitivity, autonomy, and robotic control. Each domain is scored on a 5-point Likert scale with anchors. We used two common robotic simulators, the dV-Trainer (dVT) and the da Vinci Skills Simulator (dVSS) to compare the performance metrics of robotic surgical simulators to the GEARS for a basic robotic task on each simulator. Prospective single-blinded randomized study SETTING: Surgical education and training center PATIENTS OR PARTICIPANTS: Surgeons, surgeons in training INTERVENTIONS: Demographic information was collected including gender, age, level of training, specialty, and previous surgical and simulator experience. Subjects performed two trials of Ring and Rail 1 (RR1) on each of two simulators (dVSS and dVT) after undergoing randomization and warm-up exercises. The second RR1 trial simulator performance was recorded and the de-identified videos were sent to human reviewers using GEARS. Eight different simulator assessment metrics were identified and paired with a similar performance metric in the GEARS tool. The GEARS evaluation scores and simulator assessment scores were paired and a Spearman's rho calculated for their level of correlation. 74 subjects were enrolled in this randomized study with 9 subjects excluded for missing or incomplete data. There was a strong correlation between GEARS score and simulator metric score for Time to Complete

    A method for registration of the sniffing component of the search behavior in rabbits subjected to food deprivation is suggested. Pulsed activities of the muscles controlling the movements of the wings of the nostrils and the pressure in the nasal cavity are recorded simultaneously. The method allows accurate artifact-free registration of the time and amplitude parameters of the sniffing component of the search behavior. The registration is realized on an MP150 programmed complex, consisting of EMG 100C biopotential amplifiers and Samba 202 intracavitary pressure recorder. The method allows synchronous real-time registration of pulsed activities of the muscles setting in motion the wings of the nostrils and the changes in the intranasal pressure in the course of search behavior of animals under conditions of food deprivation without limiting their locomotor activity.

    To examine the effect of cognitive-behavioral therapy for insomnia (CBT-I) on the underreporting of sleep relative to objective measurement, a common occurrence among individuals with insomnia. Pre-treatment and post-treatment self-report measures of sleep were compared with those obtained from home-based polysomnography (PSG) in 60 adults (mean age = 69.17; 42 women) with comorbid insomnia. The self-report data were published previously in a randomized controlled trial demonstrating the efficacy of CBT-I compared with a placebo treatment. Self-report measures significantly underestimated sleep at pre-treatment and CBT-I led to a correction in this discrepancy. There were no significant changes in PSG after CBT-I. Path analysis showed that an increase in an objective proxy measure of sleep quality (i.e., decreased stage N1 sleep) after CBT-I was significantly related to improvements in self-report of sleep, with full mediation by reductions in discrepancy. This is the first CBT-I outcome study to analyze discrepancy changes and demonstrate that these changes account for a significant portion of self-report outcome. In addition, improved sleep quality as measured by a decrease in percentage of stage N1 sleep following treatment may be one mechanism that explains why sleep estimation is more accurate following CBT-I. © 2012 Wiley Periodicals, Inc.

  13. Muscle repositioning: combining subjective and objective feedbacks in the teaching and practice of a reflex-based myofascial release technique.

    Muscle Repositioning (MR) is a new style of myofascial release that elicits involuntary motor reactions detectable by electromyography. This article describes the principal theoretical and practical concepts of MR, and summarizes a workshop presented October 31, 2009, after the Second International Fascia Research Congress, held at Vrije Universitiet, Amsterdam.The manual mechanical input of MR integrates the client's body segments into a block, which is evident as a result of the diagnostic manual oscillations the practitioner imparts to the client's body. Segmental integration is achieved when the client's body responds as a unit to the oscillatory assessment. It appears that manually sustaining the condition of segmental integration evokes involuntary muscle reactions, which reactions might correspond to mechanisms that maintain homeostasis, such as pandiculation. It might be that these reactions are part of the MR mechanism of action and underlie its clinically observed efficacy in the treatment of musculoskeletal disorders.For the practitioner and the client alike, segmental integration provides unique sensations. In teaching MR, these paired sensations can be used as kinesthetic feedback resources, because quality of touch can be guided by the client's reported sensations, which should match the practitioner's sensations. Another form of feedback with respect to quality of touch is the visually discernable degree of segmental integration. Finally, because the involuntary motor activity elicited by the MR touch can be objectively monitored through electromyography and possibly other instrumented measurements, the MR approach might yield objectivity, precision, and reproducibility-features seldom found in manual therapies.

    Different studies considered the mechanisms involved in the maintenance of binge eating in bulimia nervosa (BN) and binge eating disorder (BED), suggesting different pathways. The present 3-year follow-up study evaluated the relationships between psychopathological variables, and objective and subjective binge eating episodes in the two syndromes. 85 BN and 133 BED patients were studied. Objective and subjective binge eating, and psychopathological data were collected in a face-to-face interview, and by means of different self-reported questionnaires. The same assessment was repeated at baseline (T0), at the end of an individual cognitive-behavioral treatment (T1), and 3 years after the end of treatment (T2). At baseline, BN and BED patients showed different emotions associated with binge eating: anger/frustration for BN and depression for BED patients. Objective binge eating frequency reduction across time was associated with lower impulsivity and shape concern in BN patients, and with lower emotional eating and depressive symptoms in BED patients. Lower subjective binge eating frequency at baseline predicted recovery, in both BN and BED patients. Recovery was associated with lower impulsivity and body shape concern at baseline for BN patients, and lower depression and emotional eating for BED patients. Eating psychopathology, psychiatric comorbidity, impulsivity and emotional eating have a different pattern of association with objective and subjective binge eating in BN and BED patients, and they act as different moderators of treatment. A different target of intervention for these two syndromes might be taken into account, and subjective binge eating deserves an accurate assessment. Copyright © 2011 S. Karger AG, Basel.

  15. A Novel Model of the Ideal Point Method Coupled with Objective and Subjective Weighting Method for Evaluation of Surrounding Rock Stability

    Full Text Available The classification of surrounding rock stability is the critical problem in tunneling engineering. In order to decrease engineering disasters, the surrounding rock stability should be accurately evaluated. The ideal point method is applied to the classification of surrounding rock stability. Considering the complexity of surrounding rock classification, some factors such as rock uniaxial compressive strengthen, integrality coefficient of rock mass, the angle between tunnel axis and the main joint, joints condition, and seepage measurement of groundwater are selected as evaluation indices. The weight coefficients of these evaluation indices are determined by the objective and subjective weighting method, consisting with the delphi method and the information entropy theory. The objective and subjective weighting method is exact and reliable to determine the weights of evaluation indices, considering not only the expert’s experiences, but also objectivity of the field test data. A new composite model is established for evaluating the surrounding rock stability based on the ideal point method and the objective and subjective weighting method. The present model is applied to Beigu mountain tunnel in Jiangsu province, China. The result is in good agreement with practical situation of surrounding rock, which proves that the ideal point method used to classify the surrounding rock in tunnels is reasonable and effective. The present model is simple and has very strong operability, which possesses a good prospect of engineering application.

    2017-01-01

    Full Text Available Illegal hunters in Africa may be making rational decisions about the hunting activities they partake in. These decisions could be linked to their socioeconomic status and the livelihood opportunities available to them. In particular, poverty is widely considered the leading driver that causes a household's inhabitants to take up poaching in protected areas. Programs aiming to protect vulnerable wildlife populations by mitigating poaching have historically relied upon income-based poverty metrics in efforts to reduce regional poverty and incentivise local inhabitants to discontinue poaching activities. Because such data sets that deal with poachers directly are rare, assumptions about the role of poverty, and the extent of poverty, that drives poaching have been hard to test. This study uses a unique sample of 173 self-admitted poachers living in villages adjacent to Ruaha National Park in Tanzania to explore the influence of poverty on poaching. Results indicated high demographic and household economy heterogeneity among poaching households. Capability deprivation examined more subjective measures of poverty and revealed that poachers are strongly motivated by the need to improve their incomes, but are not necessarily the poorest of the poor.

    Epidemiological studies on sleep often use questionnaires, and measurement of validity provides necessary guidance in selection of valid single sleep questions. Twenty-five items assessing different aspects of sleep, including overall sleep quality, specific sleep parameters, nocturnal restoration, and exposure-related questions, were tested. This involved coherence with objective polysomnographic (PSG) laboratory measurements of sleep in 47 participants and application of selected items under field conditions in over 3,000 participants. Items on overall sleep quality correlated significantly with PSG data. For specific sleep parameter questions, tiredness in the morning, time to fall asleep, difficulties to sleep and estimated number of awakenings were correlated to PSG data. Questions asking specifically about the effect of potential sleep disturbances correlated poorly with PSG data, but showed highest effects between environmental exposure (noise and vibration) and control nights in the laboratory and highest correlation with the dose of exposure in the field. In conclusion, healthy participants seem to be able to access their sleep reliably; and sleep questions asking about specific sleep parameters can be recommended for the assessment of sleep.

Contextualizing these self-portraits, I show the works that led up to me returning to the self as a focus for sculpture driven by feelings of the responsibility of heritage. Points for reflection centre on the formal, visual and sculptural devices I have selected for expression, such as the circle, the condensed relief form, the edge, and the omissions such as backgrounds and composition.My portraiture tends to favor family and figureheads (e.g. Freud, the father(s, Mary, Moses, Picasso. I ask: has my interest in the relief format led to an interest in portraiture and hence family or has my need to touch base with feelings of ‘home’ and ‘family’ driven my interest in the relief form?   In the discussion of the work of Jane McAdam Freud are caught some points related to the work of sublimation, and memory, from the perspective of a creative work that is put in place by the dream/artistic work

    Public reporting is at the forefront of health care reform. To investigate whether patient satisfaction as expressed in a public reporting platform correlates with objective outcomes for cranial neurosurgery patients. We performed a cohort study involving patients undergoing cranial neurosurgery from 2009 to 2013 who were registered in the Statewide Planning and Research Cooperative System database. This cohort was merged with the corresponding data from the Centers for Medicare and Medicaid Services Hospital Compare website. The association of patient satisfaction metrics with outcomes was examined with the use of a propensity-adjusted regression model. Overall, 19 591 patients underwent cranial neurosurgery during the study. Using a propensity-adjusted multivariable regression analysis, we demonstrated that hospitals with a greater percentage of patient-assigned "high" scores had decreased mortality (OR, 0.60; 95% CI, 0.53-0.67), rate of discharge to rehabilitation (OR, 0.93; 95% CI, 0.88-0.98), length of stay (adjusted difference, -1.29; 95% CI, -1.46 to -1.13), and hospitalization charges (adjusted difference, -23%; 95% CI, -36% to -9%) after cranial neurosurgery. Similar associations were identified for hospitals with a higher percentage of patients, who would recommend these institutions to others. In a Centers for Medicare and Medicaid Services Hospital Compare-Statewide Planning and Research Cooperative System merged dataset, we observed an association of higher performance in patient satisfaction measures with decreased mortality, rate of discharge to rehabilitation, hospitalization charges, and length of stay.

In this paper, a method based on Adaboost algorithm is proposed for the classification of subjec-tive and objective sentences. The research status and general process of the subjective and objective classification are introduced. Then Adaboost algorithm is introduced and some related improvements are done to avoid the degeneration phenomenon. Finally, lexical fea-ture and 2-POS feature are taken as an input to classify short texts. The experimental results show that Adaboost has a good effect in the application of the subjective and objective classification.

    Full Text Available Abstract Background The aim of this work was to introduce a new combined method of subjective and objective measures to assess psychosocial risk factors at work and improve workers’ health and well-being. In the literature most of the research on work-related stress focuses on self-report measures and this work represents the first methodology capable of integrating different sources of data. Method An integrated method entitled St.A.R.T. (STress Assessment and Research Toolkit was used in order to assess psychosocial risk factors and two health outcomes. In particular, a self-report questionnaire combined with an observational structured checklist was administered to 113 workers from an Italian retail company. Results The data showed a correlation between subjective data and the rating data of the observational checklist for the psychosocial risk factors related to work contexts such as customer relationship management and customer queue. Conversely, the factors related to work content (workload and boredom measured with different methods (subjective vs. objective showed a discrepancy. Furthermore, subjective measures of psychosocial risk factors were more predictive of workers’ psychological health and exhaustion than rating data. The different objective measures played different roles, however, in terms of their influence on the two health outcomes considered. Conclusions It is important to integrate self-related assessment of stressors with objective measures for a better understanding of workers’ conditions in the workplace. The method presented could be considered a useful methodology for combining the two measures and differentiating the impact of different psychological risk factors related to work content and context on workers’ health.

Methods: A comparative research of sleep disorder was made to 30 cases of depression and 20 normals. A comparative research of objective sleep and subjective sleep was made to 30 cases of depressions. Results: Ttie indicators of PSG (sleep time, sleep latency, awakening number, awakening time, AT/rST%, total sleep time, sleep efficiency, sleep maintenance, SI and S2) in depressions were significantly different than those in controls. The indicators of PSQI (PSQI total score, sleep efficiency, total sleep time, sleep latenc) in depressions were significantly different than those in controls. The sleep efficiency and actual sleep of objective sleep in depressions and insomnia were significantly higher than those of subjective sleep, and sleep latency was contrary. Conclusion: Depression in patients with subjective sleep and objective sleep abnormalities exist in a certain degree, subjective depressions have a tendency to exaggerate their sleep disorders.

    We sought to evaluate the ability of the Identification of Seniors At Risk (ISAR) tool to differentiate between older adult patients having a poor outcome within 30 days of emergency department (ED) care and those who do not. We compare prognostic accuracy of subjective versus objective risk factors. 202 community-dwelling patients age 65 years and older presenting to two EDs were prospectively enrolled. Participants completed the six-question ISAR and objective testing (cognition, ambulation, vision). We reviewed electronic medical records for current medications, hospitalisations in the past six months, ED disposition, length of hospital stay, subsequent ED visits or inpatient admissions or death at 30 days. Participants were given a point for each risk factor present; subjective and objective risk factors were scored separately. We tested ability of individual risk factors and scores to predict a composite outcome of subsequent ED visit, postdischarge hospitalisation or death by day 30 after the index ED visit. We computed receiver operating curve area under the curves (AUC) to determine tool discrimination. 23% of participants had a poor 30-day outcome. The optimum subjective ISAR cut-off score for screening was ≥2, which was present in 84% of participants, had a sensitivity of 91% and specificity of 19%. Using the subjective ISAR tool, the AUC was 0.66. The optimum objective ISAR-related risk cut-off score for screening was ≥3, which was present in 82% of participants, had a sensitivity of 87% and specificity of 40%. Using the objective ISAR-related tool, the AUC was 0.69. The self-reported ISAR tool did not discriminate well between older adults with or without 30-day hospital revisit or death. An optimum score of ≥2 would identify many older adults at no apparent increased risk of poor outcomes at 30 days. Using objective ISAR-related risk factors did not improve overall discrimination.

    We evaluated the subjective image impression of two different magnetic resonance (MR) sequences by using a subjective ranking system. This ranking system was based on 20 criteria describing several tissue characteristics such as the signal intensity of normal anatomical structures and the changes of signal intensities and shape of lesions as well as artefacts. MR of the vertebral spine was performed in 48 female and 52 male patients (mean age 44.8 years) referred consecutively for investigation of a back problem. Ninety-six pathologies were found in 82 patients. Sagittal and axial T1 weighted spin-echo before and after administration of Gadolinium (Gd-DOTA), and sagittal T2 weighted spin-echo (T2wSE) and Turbo-spin-echo (TSE) sequences were performed by means of surface coils. Using the subjective ranking system the sagittal T2wSE and sagittal TSE were compared. Both sequences were suitable for identification of normal anatomy and pathologic changes and there was no trend for increased detection of disease by one imaging sequence over the other. We found that sagittal TSE sequences can replace sagittal T2wSE sequences in spinal MR and that artefacts at the cervical and lumbar spine are less frequent using TSE, thus confirming previous studies. In this study, our ranking system reveiled, that there are differences between the subjective judgement of image qualities and objective measurement of SNR. However, this approach may not be helpful to compare two different MR sequences as it is limited to the anatomical area investigated and is time consuming. The subjective image impression, i.e. the quality of images, may not always be represented by physical parameters such as a signal-to-noise ratio (SNR), radiologists should try to define influences of image quality also by subjective parameters.

    Full Text Available We live in a society where the consumer, due to the diversity and abundance of products and services whose characteristics are becoming more similar, has to make choices that are increasingly difficult. Another aspect that has led to a profound transformation of the consumer behavior is due to the large volume of information, supplied by the Internet, information which in some cases is not accurate, but is decisively influencing the consumer. In equal measure, the difficulty of making a purchasing decision is caused by the fact that with the opening to the global market, where the products and services were depersonalized, gaining common features, and where the concept of quality tends to no longer relate to the same standards as a few decades ago, having suffered major changes. The quality of products is a fundamental requirement of competitiveness, and quality assessment is a personal right of the consumer, because this is a direct effect of quality of life.

    2011-01-01

    There is increasing pressure on recent dental school graduates to understand and successfully utilize patient management and business management strategies to run a productive dental office. Dental schools are faced with the dilemma to either add more credit hours in their already crowded curriculum or adjust predental school requirements. All fifty-nine U.S. dental schools were assessed online to determine admission requirements in the areas of behavioral science and business education. Results show that only 11.9 percent of the schools require prerequisite course work in behavioral science and no school requires prerequisite course work in business. However, 64.4 percent and 30.5 percent of schools encouraged or recommended prerequisite course work in behavioral science and business, respectively. We suggest that the dental education community involve key stakeholders to discuss the incorporation of prerequisite course work in behavioral science and business. Additional courses in these disciplines would provide dental students better backgrounds from which the dental curriculum could build a more advanced and applied perspective to better prepare students for practice.

    University students often have sleep issues that arise from poor sleep hygiene practices and technology use patterns. Yet, technology-related behaviors are often neglected in sleep hygiene education. This study examined whether the Sleep Treatment Education Program for Students-modified to include information regarding managing technology use (STEPS-TECH)-helps improve both subjective and objective sleep outcomes among university students. Results of an experimental study among 78 university students showed improvements in objective indicators of sleep quantity (total sleep time) and sleep quality (less awakenings) during the subsequent week for students in the STEPS-TECH intervention group compared to a control group. Exploratory analyses indicated that effects were driven by improvements in weekend days immediately following the intervention. There were also no intervention effects on subjective sleep quality or quantity outcomes. In terms of self-reported behavioral responses to educational content in the intervention, there were no group differences in sleep hygiene practices or technology use before bedtime. However, the intervention group reported less technology use during sleep periods than the control group. These preliminary findings suggest that STEPS-TECH may be a useful educational tool to help improve objective sleep and reduce technology use during sleep periods among university students.

    Patient adherence to treatment is key to preventing the worsening of neurological disability in multiple sclerosis (MS). The RebiSmart® autoinjector facilitates self-administration of subcutaneous interferon β-1a (sc IFN β-1a) and records objective adherence data. The CORE study was undertaken to evaluate the relationship between subjectively reported and objective adherence of MS patients using RebiSmart® in Switzerland and explore variables associated with objective adherence. Patients with relapsing-remitting MS who were treated with sc IFN β-1a 44 or 22 μg three times weekly using RebiSmart® for at least 9 months participated in this phase IV non-interventional study. Neurologist questionnaires were used at month 0 to collect patient demographics, medical history and estimates of patients' adherence. Patient questionnaires were used to record subjective patient-reported adherence at month 0 and estimates of variables influencing adherence. Objective adherence data were obtained from the RebiSmart® log-files at months 0 and 6. Of 56 patients who completed the observation period, 53 had evaluable data. Objective adherence differed significantly between self-reported compliant (n = 33) and non-compliant groups (n = 20) (p = 0.00001). Older age, greater disability, patient's perception of the importance of ease of use and storage, being well informed about RebiSmart® features and neurologists' estimations of adherence were all positively associated with treatment adherence. We showed for the first time that subjective patient-reported adherence in MS was well in line with objective adherence, suggesting that the frequency of administration is reported accurately by patients to their neurologist. This observation may have implications for future treatment monitoring strategies and strategic medical decisions. Patients, particularly those who are younger and with lower levels of disability, may benefit from being better informed of the importance of

    Work performed on scaffolds carries the risk of falling that disproportionately threatens the safety and health of novice construction workers. Hence, objective measures of the postural stability, cardiovascular stress, and subjective difficulty in maintaining postural balance were evaluated for four expert and four novice construction workers performing a manual task in a standing posture on a scaffold with and without safety handrails at two different elevation heights. Based on a multivariate analysis of variance, the experience, scaffold height, and presence of a handrail were found to significantly affect measures of the postural stability and cardiovascular stress. At a lower level of worker experience, a higher scaffold height, and in the absence of a handrail (which may correspond to higher risk of a fall), postural stability was significantly reduced, while cardiovascular stress and subjective difficulties in maintaining postural balance increased. We emphasize the importance of training and handrails for fall prevention at construction sites.

    Although the restless legs syndrome (RLS) is a disorder with a relatively high prevalence rate (8% in Austria) and leads to insomnia and excessive daytime tiredness, there is a paucity of sleep laboratory data concerning objective and subjective sleep and awakening quality. Thus, the aim of this study was to investigate 12 untreated RLS patients as compared with 12 normal controls and subsequently measure the acute effects of 0.5 mg ropinirole (Requip((R))) - a nonergoline dopamine agonist - as compared with placebo. In 3 nights (adaptation, placebo, ropinirole night) sleep induction, maintenance and architecture were measured objectively by polysomnography, subjective sleep and awakening quality were assessed by self-rating scales and visual-analog scales, and objective awakening quality was evaluated by a psychometric test battery. In polysomnography, RLS patients demonstrated, as compared with normal controls, a decreased total sleep time (TST) and sleep efficacy, increased wakefulness during the total sleep period and frequency of nocturnal awakenings, increased sleep stage S1, decreased S2 and increased stage shifts. Subjective sleep quality tended to decrease, and morning well-being, mood, affectivity and wakefulness were deteriorated. In the noopsyche, fine motor activity and reaction time performance were deteriorated. Ropinirole 0.5 mg induced, as compared with placebo, an increase in TST, sleep efficacy, S2 sleep and stage shifts. In the morning, somatic complaints increased slightly, while fine motor activity and reaction time performance improved. Our findings suggest a key-lock principle in the diagnosis/treatment of RLS and a dopaminergic mechanism in its pathogenesis, which is supported by the data on periodic leg movements during sleep and arousals of the subsequent paper.

  2. The argument for an objective wave function collapse: Why spontaneous localization collapse or no-collapse decoherence cannot solve the measurement problem in a subjective fashion

    A more detailed analysis of the measurement problem continues to support the position taken by Shimony and the author that collapse of the wave function takes place in an objective manner in the rhodopsin molecule of the retina. This casts further doubts on the theories involving a spontaneous localization collapse process or a no-collapse decoherence process taking place in the visual cortex in a subjective fashion. The possibility is then raised, as per Anandan, as to whether the solution of the measurement problem in quantum theory allows one to address the problem of quantizing gravitation.

    Despite the ubiquity of prerequisites in undergraduate science, technology, engineering, and mathematics curricula, there has been minimal effort to assess their value in a data-driven manner. Using both quantitative and qualitative data, we examined the impact of prerequisites in the context of a microbiology lecture and lab course pairing. Through interviews and an online survey, students highlighted a number of positive attributes of prerequisites, including their role in knowledge acquisition, along with negative impacts, such as perhaps needlessly increasing time to degree and adding to the cost of education. We also identified a number of reasons why individuals do or do not enroll in prerequisite courses, many of which were not related to student learning. In our particular curriculum, students did not believe the microbiology lecture course impacted success in the lab, which agrees with our analysis of lab course performance using a previously established "familiarity" scale. These conclusions highlight the importance of soliciting and analyzing student feedback, and triangulating these data with quantitative performance metrics to assess the state of science, technology, engineering, and mathematics curricula.

    Benzodiazepines are frequently long-term prescribed for the treatment of patients with severe mental illness. This prescribing practice is problematic because of well-described side effects including risk of dependence. We examined the efficacy of prolonged-release melatonin on objective and subjective sleep quality during benzodiazepine discontinuation and whether sleep variables were associated with benzodiazepine withdrawal. Eligible patients included adults with a diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder and long-term use of benzodiazepines in combination with antipsychotics. All participants gradually tapered the use of benzodiazepines after randomization to add-on treatment with melatonin versus placebo. Here we report a subsample of 23 patients undergoing sleep recordings (one-night polysomnography) and 55 patients participating in subjective sleep quality ratings. Melatonin had no effect on objective sleep efficiency, but significantly improved self-reported sleep quality. Reduced benzodiazepine dosage at the 24-week follow-up was associated with a significantly decreased proportion of stage 2 sleep. These results indicate that prolonged-release melatonin has some efficacy for self-reported sleep quality after gradual benzodiazepine dose reduction, and that benzodiazepine discontinuation is not associated with rebound insomnia in medicated patients with severe mental illness. However, these findings were limited by a small sample size and a low retention rate.

    Sex differences in pain perception are known to exist; however, the exact pathomechanism remains unclear. This work aims to elucidate sex differences in subjective and objective measures of pain, functional impairment, and health-related quality of life (HRQoL) in patients with lumbar degenerative disc disease. In a prospective 2-center study, back and leg pain (visual analogue scale [VAS]), functional disability (Oswestry Disability Index and Roland-Morris Disability Index), and HRQoL (EuroQol-5D and Short Form [SF12]) were collected for consecutive patients undergoing lumbar spine surgery. Objective functional impairment (OFI) was estimated using age-adjusted and sex-adjusted cutoff values for the timed-up-and-go (TUG) test. A healthy cohort of n = 110 subjects served as the control group. Univariate and multivariate analyses were performed to test the association between sex and pain, subjective and OFIs, and HRQoL. The study comprised n = 305 patients (41.6% females). Female patients had more VAS back pain (P = 0.002) and leg pain (P = 0.014). They were more likely to report higher functional impairment in terms of Oswestry Disability Index (P = 0.005). Similarly, HRQoL measured with the EuroQol-5D index (P = 0.012) and SF12 physical composite score (P = 0.005) was lower in female patients. Female patients reported higher VAS back and leg pain, functional impairment, and reduced HRQoL than male patients. However, there were no sex differences with respect to the presence and degree of OFI measured by the TUG test using age-adjusted and sex-adjusted cutoff values. As such, the TUG may be a good test to overcome sex bias for the clinical assessment of patients with degenerative disc disease.

    Full Text Available Purpose: To determine the agreement among the items of the Korean physical therapist licensing examination, learning objectives of class subjects, and physical therapists’ job descriptions. Methods: The main tasks of physical therapists were classified, and university courses related to the main tasks were also classified. Frequency analysis was used to determine the proportions of credits for the classified courses out of the total credits of major subjects, exam items related to the classified courses out of the total number of exam items, and universities that offer courses related to the Korean physical therapist licensing examination among the surveyed universities. Results: The proportions of credits for clinical decision making and physical therapy diagnosis-related courses out of the total number credits for major subjects at universities were relatively low (2.06% and 2.58%, respectively. Although the main tasks of physical therapists are related to diagnosis and evaluation, the proportion of physiotherapy intervention-related items (35% was higher than that of examination and evaluation-related items (25% on the Korean physical therapist licensing examination. The percentages of universities that offer physical therapy diagnosis and clinical decision making-related courses were 58.62% and 68.97%, respectively. Conclusion: Both the proportion of physiotherapy diagnosis and evaluation-related items on the Korean physical therapist licensing examination, and the number of subjects related to clinical decision making and physical therapy diagnosis in the physical therapy curriculum, should be increased to ensure that the examination items and physical therapy curriculum reflect the practical tasks of physical therapists.

    In schizophrenic disorders, supportive psychosocial therapies have been used as adjuncts to pharmacotherapy to help alleviate residual symptoms and to improve social functioning and quality of life. Among these therapies, psychoeducational therapies showed a significant efficacy on improving drug adherence and on reducing relapses. However, according to the French Health Agency, fewer than 10% of psychiatric structures in France offer registered psychoeducation programs. Caregiver apprehension of patients' depressive reactions to the awareness of the disease could underlie the underuse of psychoeducation therapies. Indeed, the psychoeducation programs' impact on objective and subjective quality of life is discussed among the literature. In this context, we conducted a retrospective, monocentric, open-labelled and non-controlled pilot study to measure the impact of a registered psychoeducation program on objective and subjective quality of life of patients suffering from schizophrenia. Secondary objectives included measures of the effects on drug observance and awareness of the disease. We included stabilized patients over the age of eighteen suffering from schizophrenia. Referent psychiatrics were asked to inform the patient of the diagnosis and to prescribe psychoeducation therapy. From 2011 to 2014, we offered three ambulatory programs, each program including fifteen two-hour group sessions. The groups were opened for three to six patients and managed by two caregivers. Themes discussed during the sessions included: schizophrenic disease, treatments, relationships to family, diet, social issues, toxics, relaxation. Objective and subjective quality of life were evaluated one month before and one month after the program using respectively the global assessment functioning (GAF) and the subjective quality of life (SQoL) scales. The Medical Adherence Rating Scale (MARS) and the French IQ8 scale evaluated respectively drug adherence and awareness of the disease. All

    Sleep problems in children are associated with poor health, behavioural and cognitive problems, as are deficiencies of long-chain omega-3 fatty acids such as docosahexaenoic acid. Theory and some evidence support a role for these fatty acids in sleep regulation, but this issue has received little formal investigation. We examined associations between blood fatty acid concentrations (from fingerstick blood samples) and subjective sleep (using an age-standardized parent questionnaire) in a large epidemiological sample of healthy children aged 7-9 years (n = 395) from mainstream UK schools. In a randomized controlled trial, we then explored whether 16-week supplementation (600 mg day(-1) ) with algal docosahexaenoic acid versus placebo might improve sleep in a subset of those children (n = 362) who were underperforming in reading. In a randomly selected subsample (n = 43), sleep was also assessed objectively via actigraphy. In 40% of the epidemiological sample, Child Sleep Habits Questionnaire scores indicated clinical-level sleep problems. Furthermore, poorer total sleep disturbance scores were associated weakly but significantly with lower blood docosahexaenoic acid (std coeff. -0.105*) and a lower docosahexaenoic acid : arachidonic acid ratio (std coeff. -0.119**). The treatment trial showed no significant effects on subjective sleep measures. However, in the small actigraphy subsample, docosahexaenoic acid supplementation led on average to seven fewer wake episodes and 58 min more sleep per night. Cautiously, we conclude that higher blood levels of docosahexaenoic acid may relate to better child sleep, as rated by parents. Exploratory pilot objective evidence from actigraphy suggests that docosahexaenoic acid supplementation may improve children's sleep, but further investigations are needed.

    The term 'common mole', often used to describe a subset of benign pigmented skin lesions, is traditionally defined on the basis of morpho-chromatic features. In recent years, certain research groups have developed equipment and methods, such as digital dermoscopy analysis, that enable objective evaluation of pigmented skin lesions. In this study we use a digital dermoscopy analyser trained for the recognition of pigmented skin lesions to compare the subjective definition of 'common' and the mathematical concept of 'close to the mean of measurements'. A subset (100) of digital images of flat pigmented lesions, obtained in daily practice, were classified by trained and non-expert clinicians as common moles (60) or clear-cut melanoma (40), and processed with a DB-Mips analyser. The resulting parameters, validated by a classifier, were used to evaluate Hotelling's T2 multivariate distances from the mean. 'Common' moles could not be clearly defined in terms of closeness to the means of objectively evaluated parameters. Their diagnosis indudes many other evaluations and clusters of variables. The clinical semantics of the term 'common' does not conform to any unambiguous mathematical definition.

    Full Text Available Prerequisite Programmes approach is a requirement for implementing a correct own check plan. This new approach, born according to the European Legislation, is completely recognized by third Nation Authorities and private Inspection and Accreditation Bodies. This method is the basis to verify if an own check system is under control and to verify if corrective actions are built up to warrant hygienic production standards. The present work demonstrate that a correct own check plan is built up only by a Pre Requisites Program approach. The new UNI EN ISO 22000:2005 standard describe this concept specifying the difference between PRP and CCP.

The Health and Retirement Study is a US nationally representative study of older adults over 50 and their spouse of any age. We restricted the sample to individuals, 65 years of age and older (n = 2591). An accelerated increase in subjective age was defined as an increase in subjective age over the two waves greater than five years. An accelerated decrease in subjective age was defined as a difference that was lower than three years. These were examined against a change in subjective age in the range of three to five years (i.e., change consistent with the passage of time). For 23.4% of the sample, changes in subjective age were consistent with the passage of time. A total of 38.3% had an accelerated decrease in subjective age, whereas 38.3% had an accelerated increase. A decrease in loneliness over the two waves resulted in an accelerated decrease in subjective age, whereas an increase in depressive symptoms resulted in an accelerated increase in subjective age. Changes in objective social indicators, physical difficulties or medical comorbidity did not predict changes in subjective age. This is one of very few studies that examined changes in subjective age over time. Changes in subjective age represent an important construct that corresponding to other changes in subjective experiences.

    To investigate low-tube-voltage 80-kVp computed tomography (CT) of head and neck primary and recurrent squamous cell carcinoma (SCC) regarding objective and subjective image quality. We retrospectively evaluated 65 patients (47 male, 18 female; mean age: 62.1 years) who underwent head and neck dual-energy CT (DECT) due to biopsy-proven primary (n = 50) or recurrent (n = 15) SCC. Eighty peak kilovoltage and standard blended 120-kVp images were compared. Attenuation and noise of malignancy and various soft tissue structures were measured. Tumor signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated. Subjective image quality was rated by three reviewers using 5-point grading scales regarding overall image quality, lesion delineation, image sharpness, and image noise. Radiation dose was assessed as CT dose index volume (CTDI{sub vol}). Interobserver agreement was calculated using intraclass correlation coefficient (ICC). Mean tumor attenuation (153.8 Hounsfield unit (HU) vs. 97.1 HU), SNR (10.7 vs. 8.3), CNR (8.1 vs. 4.8), and subjective tumor delineation (score, 4.46 vs. 4.13) were significantly increased (all P < 0.001) with 80-kVp acquisition compared to standard blended 120-kVp images. Noise of all measured structures was increased in 80-kVp acquisition (P < 0.001). Overall interobserver agreement was good (ICC, 0.86; 95 % confidence intervals: 0.82-0.89). CTDI{sub vol} was reduced by 48.7 % with 80-kVp acquisition compared to standard DECT (4.85 ± 0.51 vs. 9.94 ± 0.81 mGy cm, P < 0.001). Head and neck CT with low-tube-voltage 80-kVp acquisition provides increased tumor delineation, SNR, and CNR for CT imaging of primary and recurrent SCC compared to standard 120-kVp acquisition with an accompanying significant reduction of radiation exposure.

    Associations between objective and subjective measures of knee function may facilitate rehabilitation in ACL-patients. The aim of this study is to investigate if a test-battery of functional and/or muscle outcomes are associated with Knee osteoarthritis outcome score (KOOS) subscales (Sport/Rec and QOL) in ACL-reconstructed patients. 23 hamstring auto-graft ACL-reconstructed men (mean age: 27.2 standard deviation 7.5 years, BMI: 25.4 standard deviation 3.2 time since surgery: 27 standard deviation 7 months) completed KOOS-questionnaire and an objective test-battery: (i) one-leg maximal jump for distance (OLJD), isometric maximal voluntary contraction (MVC) for (ii) knee extensors and (iii) flexors, and (iv) maximal counter movement jump (CMJ). Sagittal kinematic data were recorded during CMJ using a 6-camera Vicon MX system. Multilevel linear regression analysis was used to determine the strength of associations between KOOS parameters (Sport/Rec and QOL) that a priori were defined as dependent variables and 4 models of independent outcomes from the test-battery. Moderate associations between OLJD and Sport/Rec (r(2)=0.26, pknee extensor or flexor MVC to the analysis (Model 2) increased the strength of the associations (up to r(2)=0.53, pknee extensor and knee flexor MVC to the analysis (Model 3) did not improve the regression model and only minor increases were observed when including kinematic data of CMJ (Model 4). Moderate-to-large proportion (31-53%) of the variation in KOOS was explained by OLJD and MVC which may add to design effective future rehabilitation interventions for ACL-patients.

    Full Text Available The authors conduct studies of economic prerequisites and factors, which resulted in writing-off significant amounts of goodwill value in Ukrainian banking institutions, which are structural parts of international financial institutions. In the result of analysis of main prerequisites the article identifies external and internal reasons of acknowledgement of devaluation of goodwill in the domestic banking sector. In accordance with the results of the study, the article identifies that acknowledgement of devaluation of goodwill testifies to a negative mood of foreign investors with respect to prospects of business development in the domestic banking market. The article justifies expediency of, separate from goodwill, identification of intangible assets, subject to acknowledgement in the result of unification of banks, in particular the client base of a bank, as an intangible asset with a final date of useful use. It proves that acknowledgement of this asset in the result of unification would allow avoiding significant amounts of write-off of goodwill value under unfavourable economic conditions. The prospect of further studies in this direction is justification of an optimal method of identification of the amount of goodwill devaluation, which would allow avoiding manipulations with financial reporting and would improve quality of presented information about the real financial state of banking institutions.

  3. Multi-Criteria Assessment of Spatial Robust Water Resource Vulnerability Using the TOPSIS Method Coupled with Objective and Subjective Weights in the Han River Basin

    Full Text Available This study developed a multi-criteria approach to spatially assess the robust water resource vulnerability in sub-basins and applied it to the Han River basin. The Intergovernmental Panel on Climate Change (IPCC suggested three factors of vulnerability; namely, exposure, sensitivity and adaptive capacity were used in this study with respect to water quantity and quality. In this study, 16 water quantity indicators and 13 water quality indicators were selected to identify the vulnerability using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS method. Environmental and socioeconomic data were obtained from the national statistics database, and hydrological data were simulated using the calibrated Soil and Water Assessment Tool (SWAT model. Expert surveys and Shannon entropy method were used to determine subjective and objective weights for all indicators, individually. As a result, water quantity-vulnerable sub-basins were associated with high water use and water leakage ratios. Water quality-vulnerable sub-basins were associated with relatively high values of maximum consecutive dry days and heatwave days. The water quantity indices of both weighting methods showed relatively similar spatial distributions, while the distribution of water quality indices was distinct. These results suggest that considering different weighting methods is important for assessing the robust water resource vulnerability of sub-basins.

    Full Text Available Abstract Background To identify objective and subjective indicators of death in prevalent hemodialysis (HD patients in a follow-up study of 12 months. Methods The study included end-stage renal disease patients undergoing HD and analyzed demographic and laboratory data from the dialysis unit's records. Baseline data concerning socioeconomic status, comorbidity, quality of life level, coping style and depression were also assessed. For variables that differed in the comparison between survivors and non-survivors, Cox proportional hazards for death were calculated. Results The mortality rate was 13.0%. Non-survivors differed in age, comorbidity, inclusion on the transplant waiting list and physical functioning score. The hazard ratios of death were 8.958 (2.843-28.223; p p = 0.007 for not being on the transplant waiting list, 1.038 (1.012-1.066; p = 0.005 for age, and 0.980 (0.964-0.996; p = 0.014 for physical functioning. Conclusions Comorbidity, not being on the transplant waiting list, age and physical functioning, which reflects physical status, must be seen as risk indicators of death among patients undergoing HD.

    This study investigated the importance of the distinction between objective (OBE) and subjective binge eating (SBE) among 80 treatment-seeking adolescents with bulimia nervosa. We explored relationships among OBEs, SBEs, eating disorder (ED) symptomatology, depression, and self-esteem using two approaches. Group comparisons showed that OBE and SBE groups did not differ on ED symptoms or self-esteem; however, the SBE group had significantly greater depression. Examining continuous variables, OBEs (not SBEs) accounted for significant unique variance in global ED pathology, vomiting, and self-esteem. SBEs (not OBEs) accounted for significant unique variance in restraint and depression. Both OBEs and SBEs accounted for significant unique variance in eating concern; neither accounted for unique variance in weight/shape concern, laxative use, diuretic use, or driven exercise. Loss of control, rather than amount of food, may be most important in defining binge eating. Additionally, OBEs may indicate broader ED pathology, while SBEs may indicate restrictive/depressive symptomatology. Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.

  6. Objective and subjective factors as predictors of post-traumatic stress symptoms in parents of children with cancer--a longitudinal study.

    Directory of Open Access Journals (Sweden)

    Annika Lindahl Norberg

    Full Text Available BACKGROUND: Parents of children with cancer report post-traumatic stress symptoms (PTSS years after the child's successful treatment is completed. The aim of the present study was to analyze a number of objective and subjective childhood cancer-related factors as predictors of parental PTSS. METHODS: Data were collected from 224 parents during and after their child's cancer treatment. Data sources include self-report questionnaires and medical records. RESULTS: In a multivariate hierarchical model death of the child, parent's perception of child psychological distress and total symptom burden predicted higher levels of PTSS. In addition, immigrants and unemployed parents reported higher levels of PTSS. The following factors did not predict PTSS: parent gender, family income, previous trauma, child's prognosis, treatment intensity, non-fatal relapse, and parent's satisfaction with the child's care. CONCLUSIONS: Although medical complications can be temporarily stressful, a parent's perception of the child's distress is a more powerful predictor of parental PTSS. The vulnerability of unemployed parents and immigrants should be acknowledged. In addition, findings highlight that the death of a child is as traumatic as could be expected.

    Background Traumatic brain injury (TBI) is extremely common across the lifespan and is an established risk factor for dementia. The cognitive profile of the large and growing population of older adults with prior TBI who do not have a diagnosis of dementia, however, has not been well described. Our aim was to describe the cognitive profile associated with prior TBI exposure among community-dwelling older adults without dementia—an understudied but potentially vulnerable population. Methods and findings In this population-based cohort study, we studied 984 community-dwelling older adults (age 51 y and older and their spouses) without dementia who had been randomly selected from respondents to the 2014 wave of the Health and Retirement Study to participate in a comprehensive TBI survey and who either reported no prior TBI (n = 737) or prior symptomatic TBI resulting in treatment in a hospital (n = 247). Mean time since first TBI was 38 ± 19 y. Outcomes assessed included measures of global cognitive function, verbal episodic memory, semantic fluency, and calculation as well as a measure of subjective memory (“How would you rate your memory at the present time?”). We compared outcomes between the two TBI groups using regression models adjusting for demographics, medical comorbidities, and depression. Sensitivity analyses were performed stratified by TBI severity (no TBI, TBI without loss of consciousness [LOC], and TBI with LOC). Respondents with TBI were younger (mean age 64 ± 10 y versus 68 ± 11 y), were less likely to be female, and had higher prevalence of medical comorbidities and depression than respondents without TBI. Respondents with TBI did not perform significantly differently from respondents without TBI on any measure of objective cognitive function in either raw or adjusted models (fully adjusted: global cognitive function score 15.4 versus 15.2, p = 0.68; verbal episodic memory score 4.4 versus 4.3, p = 0.79; semantic fluency score 15.7 versus

We found it thought-provoking to read how novel interventions, such as sharing errors, among the team can reduce the frequency of error recurrence in the future. We are hopeful that if such interventions were applied to other areas of health care, it would yield similar results. Having said this, we strongly believe that an important prerequisite of openness among health care workers is required for such interventions to work. View the original paper by Chua et al

    Numerous studies assessed the effects of smoking on lumbar degenerative disk disease (DDD); they focused on patient-reported outcome measures (PROMs) and yielded conflicting results. In this 2-center study on consecutive patients receiving surgical treatment for lumbar DDD, subjective functional impairment (SFI) in terms of PROMs including visual analog scale back and leg pain, Roland-Morris, Oswestry Disability Index, Euro-Qol-5D, and a Short-Form 12 physical component summary was determined at baseline, 3 days, 6 weeks, 6 months, and 1 year postoperatively. Age- and sex-adjusted T-scores of objective functional impairment (OFI) were determined using the Timed Up and Go test up to 6 weeks postoperatively. The responder status was defined by the minimal clinically important difference. We analyzed 375 patients (n = 96 [25.6%] smokers and n = 279 [74.4%] nonsmokers). SFI on any of the PROMs before treatment was similar in smokers and nonsmokers. Smokers were more likely to have OFI in univariate logistic regression analysis (95% confidence interval 1.31-3.37, P = 0.002). In multivariate analysis, however, this relationship became insignificant (95% confidence interval 0.85-2.38, P = 0.184). The smoking status had no predictive capacity on the 6-week SFI or OFI responder status, and there were no differences in any of the PROMs until the 1-year follow-up. PROMs measuring SFI for pain intensity, functional impairment, and health-related quality of life were similar in smokers and nonsmokers before surgery for lumbar DDD, as well as postoperatively. The smoking status has negligible impact on the Timed Up and Go test, which appears to be a robust assessment tool for OFI. Copyright © 2016 Elsevier Inc. All rights reserved.

    2011-07-01

    Full Text Available Engineering students tend to pay more attention to their core subject classes rather than on an English language class. They all come from different social and academic backgrounds and their knowledge of English language varies from one another. A mixed ability group throws many challenges to an English language teacher teaching to a grown up or rather adult group of learners who always pre-define their interests and needs. The primary and the most important challenge in front of the language teacher teaching engineering students is - how to promote active learning in MAC situation? A language teacher to overcome the problems of a mixed ability classroom and promote active learning needs to adopt a number of strategies. The paper studies the MAC situation in an English language classroom of engineering students and makes an attempt to re-define methods for active learning a prerequisite for language development in an engineering classroom.

    Inadequate funding for health is a challenge to attaining health-related Millennium Development Goals. Significant increase in health funding was recommended by the Commission for Macroeconomics and Health. Indeed Official Development Assistance has increased significantly in Uganda. However, the effectiveness of donor aid has come under greater scrutiny. This paper scrutinizes the prerequisites for aid effectiveness. The objective of the study was to assess the prerequisites for effectiveness of donor aid, specifically, its proportion to overall health funding, predictability, comprehensiveness, alignment to country priorities, and channeling mechanisms. Secondary data obtained from various official reports and surveys were analyzed against the variables mentioned under objectives. This was augmented by observations and participation in discussions with all stakeholders to discuss sector performance including health financing. Between 2004-2007, the level of aid increased from US$6 per capita to US$11. Aid was found to be unpredictable with expenditure varying between 174-8722;360 percent from budgets. More than 50% of aid was found to be off budget and unavailable for comprehensive planning. There was disproportionate funding for some items such as drugs. Key health system elements such as human resources and infrastructure have not been given due attention in investment. The government's health funding from domestic sources grew only modestly which did not guarantee fiscal sustainability. Although donor aid is significant there is need to invest in the prerequisites that would guarantee its effective use.

    Full Text Available The goal of the article lies in the study of organisational and infrastructure prerequisites of creation and functioning of integration structures capable, on the basis of logistics, of assisting subjects of economy in structuring and optimisation of material flows and also accompanying financial and information flows. In the result of the study the article identifies irregularities of the transition of national economies to new models of development and prospects of development of logistic provision of the innovation economy connected with them, transformation possibilities and prospects of international integration of the logistic market of Ukraine; it analyses prerequisites and substantiates expediency and shows benefits of formation of an international logistic centre in the city of Ternopil. The mission of the planned international logistic centre is ensuring a qualitatively new level of logistic provision of market participants, which would correspond with the existing world standards. The logistic centre performs realisation of its tasks and conduct of functions in the process of interaction with partners – participants of the logistic chain. The logistic centre should become an operator of flows of transit and export-import cargoes and it would perform important logistic functions connected not only with organisation of shipping operations but also with sorting, storing, packing and some other functions at the level of the best world representatives of the logistic servicing. In order to ensure successful activity of such a centre, it is required to adapt tariff policy of the state to international standards, to expand a list of relevant services, to reduce terms of cargo handling and to introduce modern technologies of information processing intensively.

    有关教学主客体的研究是当代教育理论的一个重要课题。从宏观教学过程这一概念出发,在理论分析和概念识读的基础上,提出教学系统的三主体双客体结构理论。按照这一理论,教学系统由三类主体(教的主体、学的主体和管理主体)和两类客体(主体性客体和单纯性客体)构成。用这一理论来指导教学工作实践,可以充分调动教学过程中的一切积极因素,协调构成教学过程的各种要素的关系,促进教学质量和教学效率的提高。%Research on the subjects and objects of teaching has always been critical in the research field of modern educational theories. Proceeding from the concept of macro teaching process, and on the basis of theoretical analy- sis and conceptual differentiation, the structural theory of "triple subjects and dual objects" is proposed in the pa- per. Under this theoretical framework, the system of teaching is viewed as comprising three subjects, namely, sub- ject of instruction, subject of learning and subject of management, and two objects, namely, subjective object and singular object. With this theory guiding teaching practices, all positive elements in the teaching process can be ef- fectively mobilized and coordinated to produce the most desirous teaching effect and teaching proficiency.

    Full Text Available Objectives: The purpose of this report is to describe the impact of a videogame-based pilot physical activity program using the Kinect for Xbox 360 game system (Microsoft, Redmond, WA on physical activity in older adults with schizophrenia. Methods: In this one group pretest posttest pilot study, twenty participants played an active videogame for 30 minutes, once a week for 6 weeks. Physical activity was measured by self-report with the Yale Physical Activity Survey and objectively with the Sensewear Pro armband at enrollment and at the end of the 6-week program. Results: There was a significant increase in frequency of self-reported vigorous physical activity. We did not detect a statistically significant difference in objectively measured physical activity although increase in number of steps and sedentary activity were in the desired direction. Conclusions: These results suggest participants’ perception of physical activity intensity differs from the intensity objectively captured with a valid and reliable physical activity monitor.

    Deaf subjects with hearing aids or cochlear implants generally find it challenging to understand speech in noisy environments where a great deal of listening effort and cognitive load are invested. In prelingually deaf children, such difficulties may have detrimental consequences on the learning process and, later in life, on academic performance. Despite the importance of such a topic, currently, there is no validated test for the assessment of cognitive load during audiological tasks. Recently, alpha and theta EEG rhythm variations in the parietal and frontal areas, respectively, have been used as indicators of cognitive load in adult subjects. The aim of the present study was to investigate, by means of EEG, the cognitive load of pediatric subjects affected by asymmetric sensorineural hearing loss as they were engaged in a speech-in-noise identification task. Seven children (4F and 3M, age range = 8-16 years) affected by asymmetric sensorineural hearing loss (i.e. profound degree on one side, mild-to-severe degree on the other side) and using a hearing aid only in their better ear, were included in the study. All of them underwent EEG recording during a speech-in-noise identification task: the experimental conditions were quiet, binaural noise, noise to the better hearing ear and noise to the poorer hearing ear. The subjects' Speech Recognition Thresholds (SRT) were also measured in each test condition. The primary outcome measures were: frontal EEG Power Spectral Density (PSD) in the theta band and parietal EEG PSD in the alpha band, as assessed before stimulus (word) onset. No statistically significant differences were noted among frontal theta power levels in the four test conditions. However, parietal alpha power levels were significantly higher in the "binaural noise" and in the "noise to worse hearing ear" conditions than in the "quiet" and "noise to better hearing ear" conditions (p hearing loss with the purpose of studying the cognitive load during

  8. CAPSIZE: A personal computer program and cross-section library for determining the shielding requirements, size, and capacity of shipping casks subject to various proposed objectives

    Energy Technology Data Exchange (ETDEWEB)

    Bucholz, J.A.

    1987-05-01

    A new interactive program called CAPSIZE has been written for the IBM-PC to rapidly determine the likely impact that proposed design objectives might have on the size and capacity of spent fuel shipping casks designed to meet those objectives. Given the burnup of the spent fuel, its cooling time, the thickness of the internal basket walls, the desired external dose rate, and the nominal weight limit of the loaded cask, the CAPSIZE program will determine the maximum number of PWR fuel assemblies that may be shipped in a lead-, steel-, or uranium-shielded cask meeting those objectives. The necessary neutron and gamma shield thicknesses are determined by the program in such a way as to meet the specified external dose rate while simultaneously minimizing the overall weight of the loaded cask. The one-group cross-section library used in the CAPSIZE program has been distilled from the intermediate results of several hundred 1-D multigroaup discrete ordinates calculations for different types of casks. Neutron and gamma source terms, as well as the decay heat terms, are based on ORIGEN-S analyses of PWR fuel assemblies having exposures of 10, 20, 30, 40, 50, and 60 gigawatt days per metric tonne of initial heavy metal (GWD/MTIHM). In each case, values have been tabulated at 17 different decay times between 120 days and 25 years. Other features of the CAPSIZE program include a steady-state heat transfer calculation which will minimize the size and weight of external cooling fins, if and when such fins are required. Comparisons with previously reported results show that the CAPSIZE program can generally estimate the necessary neutron and gamma shield thicknesses to within 0.16 in. and 0.08 in., respectively. The corresponding cask weights have generally been found to be within 1000 lbs of previously reported results. 13 refs., 20 figs., 54 tabs.

  14. Determination of prerequisites for implementation of IPOs in the Czech capital market

    Full Text Available In advanced markets, IPOs represent an opportunity to obtain the necessary capital for further company development. This form of financing is significant not only for the joint-stock company itself, for which an IPO is an alternative to debt financing, but also for further development of the capital market as a whole. That is to say, one of the fundamental functions of the capital market, the allocation function, is accomplished by means of IPOs. It follows from investigations of the situation in IPOs in the Czech Republic that financing company development through IPOs, which are linked with entrance into the capital market, has not become common practice in the Czech capital market. Comparing the present situation with the situation in international markets, it must be stated that the Czech capital market shows anomalies not only with regard to advanced capital markets such as those in the USA or Japan but also in reference to markets in Central and Eastern Europe. In the past, unfavourable conditions resulting from legislation and the institutional environment were considered the major cause of the long-term low numbers of initial public offerings in the Czech Republic. It follows from the results of the analysis of legislative barriers to carrying out IPOs that in recent years, a number of steps were taken to draw the Czech capital market nearer to the European standard, at least formally. Laws were passed that determine the scope and regulations for entrepreneurial activities of individual subjects, and an independent authority was set up that kept an eye on the tran­spa­ren­cy of the market and compliance with the given regulations; there are institutional and technical prerequisites available that facilitate trade in securities. Nowadays there are no more any legislative or general economic barriers, designated as significant obstacles for IPO realization in the Czech environment in the past. It depends mainly on approach of individual

    A physically active lifestyle has been related to positive health outcomes and high life expectancy, but the underlying psychological mechanisms maintaining physical activity are rarely investigated. Tremendous technological progress yielding sophisticated methodological approaches, i.e., ambulatory assessment, have recently enabled the study of these mechanisms in everyday life. In practice, accelerometers allow to continuously and objectively monitor physical activity. The combination with e-diaries makes it feasible to repeatedly assess mood states in real-time and real life and to relate them to physical activity. This state-of-the-art methodology comes with several advantages, like bypassing systematic distortions of retrospective methods, avoiding distortions seen in laboratory settings, and revealing an objective physical activity assessment. Most importantly, ambulatory assessment studies enable to analyze how physical activity and mood wax and wane within persons over time in contrast to existing studies on physical activity and mood which mostly investigated between-person associations. However, there are very few studies on how mood dimensions (i.e., feeling well, energetic and calm) drive non-exercise activity (NEA; such as climbing stairs) within persons. Recent reviews argued that some of these studies have methodological limitations, e.g., scarcely representative samples, short study periods, physical activity assessment via self-reports, and low sampling frequencies. To overcome these limitations, we conducted an ambulatory assessment study in a community-based sample of 106 adults over 1 week. Participants were asked to report mood ratings on e-diaries and to wear an accelerometer in daily life. We conducted multilevel analyses to investigate whether mood predicted NEA, which was defined as the mean acceleration within the 10-min interval directly following an e-diary assessment. Additionally, we analyzed the effects of NEA on different time frames

    Full Text Available Entrepreneurship research is progressing towards the construction of indexes that integrate the information of the three predominant approaches: the entrepreneurial activity output; the population’s entrepreneurial behavior, values and aspirations; and the context in which entrepreneurship takes place. In this study we compare the Global Competitiveness Index data, one of the objective sources of information selected among those recognized as descriptors of national contexts, with the national entrepreneurial context qualitative information provided by the Global Entrepreneurship Monitor. The main purpose of this research is to contribute to the knowledge of entrepreneurial context sources of information by opening a discussion around the usefulness and contribution that could make the Global Entrepreneurship Monitor source in this field, and to determine if it is recommendable to proceed to its formal validation in the short time. The obtained results evidence that the two sources do not overlap to the degree of substituting one by the other and that the Global Entrepreneurship Monitor provides relevant qualitative details about the state of entrepreneurial context that are interesting to complement the Global Competitiveness Index information. The conclusion is to recommend the formal validation of this source, being also necessary to make comparisons with other relevant sources and to clear up its role in the progress of the integrated indexes construction.

    This research aimed at optimizing computational chest radiographic images (in previous posterior projection-PA). To this end, we used a homogeneous patient equivalent phantom in Computational Imaging System calibration, in order to obtain a satisfactory noise signal relation for a diagnosis, adjusting to a minimum dose received by the patient. The techniques have been applied in an anthropomorphic phantom (RANDO). The images obtained were evaluated by a radiologist, which identified the best image to determine possible pathologies (fracture or pneumonia). The technique were quantified objectively (Detective Quantum Efficiency - DQE, Modulation Transfer Function MTF, Noise Power Spectrum, NPS). Comparing optimized techniques with the clinical routine, it is concluded that all provide doses below reference levels. However the choice of the best technique for viewing possible pneumonia and/or fracture, was determined based on the first 3D (Dose, Diagnostic, Dollar) and regarded as gold standard. This image presented a reduction of dose and loading of tube around 70.5% and 80% respectively when compared with the clinical routine.

  1. Capabilities and Choices: Do They Make Sen'se for Understanding Objective and Subjective Well-Being? An Empirical Test of Sen's Capability Framework on German and British Panel Data.

    In Sen's Capability Approach (CA) well-being can be defined as the freedom of choice to achieve the things in life which one has reason to value most for his or her personal life. Capabilities are in Sen's vocabulary therefore the real freedoms people have or the opportunities available to them. In this paper we examine the impact of capabilities alongside choices on well-being. There is a lot of theoretical work on Sen's capability framework but still a lack of empirical research in measuring and testing his capability model especially in a dynamic perspective. The contribution of the paper is first to test Sen's theoretical CA approach empirically using 25 years of German and 18 years of British data. Second, to examine to what extent the capability approach can explain long-term changes in well-being and third to view the impact on subjective as well as objective well-being in two clearly distinct welfare states. Three measures of well-being are constructed: life satisfaction for subjective well-being and relative income and employment security for objective well-being. We ran random and fixed effects GLS models. The findings strongly support Sen's capabilities framework and provide evidence on the way capabilities, choices and constraints matter for objective and subjective well-being. Capabilities pertaining to human capital, trust, altruism and risk taking, and choices to family, work-leisure, lifestyle and social behaviour show to strongly affect long-term changes in subjective and objective well-being though in a different way largely depending on the type of well-being measure used.

    Wright, Robin; Cotner, Sehoya; Winkel, Amy

    2009-01-01

    Curriculum design assumes that successful completion of prerequisite courses will have a positive impact on student performance in courses that require the prerequisite. We recently had the opportunity to test this assumption concerning the relationship between completion of the organic chemistry prerequisite and performance in introductory biochemistry. We found no statistically significant differences between average biochemistry grades or grade distribution among students with or without the organic chemistry prerequisite. However, students who had not completed the organic chemistry prerequisite before biochemistry were more likely to withdraw from the course than those who had completed the prerequisite. In contrast to the lack of correlation between performance in biochemistry and completion of organic chemistry, we observed a strong, highly significant positive relationship between cumulative GPA and the biochemistry grade. Our data suggest that excluding students without organic chemistry would have less positive impact on student success in biochemistry than would providing additional support for all students who enroll in biochemistry with a cumulative GPA below 2.5.

    Prerequisite programs are considered the most efficient tool for a successful implementation of self-control systems to ensure food safety. The main objective of this study was to evaluate the implementation of these programs in 15 catering services located in Navarra and the Basque Country (regions in northern Spain), through on-site audits and microbiological analyses. The implementation of the prerequisite program was incomplete in 60% of the sample. The unobserved temperature control during both the storage and preparation of meals in 20% of the kitchens reveals misunderstanding in the importance of checking these critical control points. A high level of food safety and hygiene (absence of pathogens) was observed in the analyzed meals, while 27.8% of the tested surfaces exceeded the established limit for total mesophilic aerobic microorganisms (≤100 CFU/25 cm²). The group of hand-contact surfaces (oven door handles and aprons) showed the highest level of total mesophilic aerobic microorganisms and Enterobacteriaceae, and the differences observed with respect to the food-contact surfaces (work and distribution utensils) were statistically significant (P food workers' hands, lower levels of microorganisms were observed in the handlers wearing gloves (that is, for Staphylococcus spp we identified 43 CFU/cm2 on average compared with 4 CFU/cm2 (P food handlers, through specific activities such as informal meetings and theoretical-practical sessions adapted to the characteristics of each establishment.

  13. DETERMINATION OF OBJECTIVES FOR URBAN FREIGHT POLICY

    Full Text Available Background: Decisions regarding strategic planning of urban freight transport very often are based on superficial assumptions inadequately reflecting the actual character of encountered challenges. The trend may be observed to adapt isolated solutions without supporting measures and verification of expected outcomes. Selected urban freight solutions have a significant potential to alleviate transport related problems, but they require unorthodox approach beyond standard traffic planning and road management. City's current planning experience must be taken into account to plan an optimized sequence of actions. Method: Due to complexity of the problem and specific decision making factors the analytic network process ANP was selected to determine relevant objective of the urban freight policy. Gdynia was selected as the subject for modeling with a review of the current freight planning practice as a first step. Then, classification of policy objective and their prerequisites were identified supported with descriptive feasibility assessment. This allowed for a development of the ANP decision-making model. Results: Considered objectives for urban freight policy were identified were optimization, reduction and transfer. After verifying relevant decision factors optimization was selected as the most feasible option for Gdynia. Other alternatives were rated around four times lower with a slight prevalence of reduction over transfer. Such ranking reflects current planning practice and availability of transferable experiences. Despite the indicative results, it must be stressed that urban freight planning should be based on the long term methodical approach not to exclude any emerging possibilities.

    Realizing that 60% to 80% of dopaminergic nigrostriatal neurons are nonfunctional at the time of clinical diagnosis, there is an emerging consensus that disease-modifying treatments should be initiated in the earliest stages of Parkinson's disease (PD). To date, clinical trial designs and metrics in PD have been focused on motor symptoms as the core feature of the clinical disease. To identify earlier or "pre-motor" populations in PD, new markers have been proposed. We address the prerequisites needed to use these pre-motor markers in clinical trials for the selection of subjects, definition of populations, and monitoring of disease progression. This may require the development of new diagnostic criteria potentially based on non-motor clinical signs, imaging techniques, or biological features, all requiring discussion in a regulatory framework. Questions addressed include: Which steps must be taken to gain a broad consensus in the field from academic opinion leaders, patient advocacy groups, regulatory bodies, and industry? How do we prevent the selection of subgroups, which may not be representative of the full disease spectrum? Is there a way forward in personalized medicine? How do we balance risk and benefit in an at-risk population? While many tools are available, a concerted effort is required to develop integrated data sets, as well as to achieve the necessary standardization for multicenter clinical trials. To this end, public-private consortia (including academic centers, patient advocacy groups, and industry) will be of crucial importance to prospectively investigate and define the best tools and treatment paradigms.

    Full Text Available The basic problems and contradictions of regional innovation policy formation in Russia are revealed. The need to move the Russian economy on an innovative way of development is seen as a condition of economic security. With the usage of global experience, priorities in innovational activity of Russian companies and measures to address systemic gaps between science and industry are grounded. Particular attention is paid to the legal aspects of the state innovational policy. Methodological approaches to the formation of regional innovational policy in the Russian Federation, taking into account the spatial distribution of the scientific, technical and production capacities of the country, their state and structure are revealed. The necessity of a major upgrade of the existing system of intergovernmental relations as a prerequisite for building a functioning innovation system is substantiated. The proposals on division of competence between the Federation and the subjects of the Russian Federation in the regulation of relations in science, technology and innovations are given.

  16. Persistent Identifiers: a Prerequisite to Establish the Framework for Scholarly Link Exchange—Scholix

    The Scholix framework—Scholarly Link Exchange—is a set of aspirational principles and practical guidelines developed under the umbrella of a joint Working Group of the Research Data Alliance (RDA) and the World Data System (WDS). It supports a global open information ecosystem unveiling the links between scholarly literature and underpinning research data. The core objectives of the framework are to (1) increase visibility and discoverability of data and articles, (2) place data in context to enable re-use, and (3) support credit attribution mechanisms. Thus, facilitating reproducibility and the transparent evaluation of science. Scholix provides an evolving lightweight set of Guidelines to increase interoperability rather than a normative standard. It consists initially of a conceptual and information models, information standards and encoding guidelines, and options for encoding and exchange protocols. An essential prerequisite to enable the proposed framework is the use of global, unique and persistent identifiers for research objects (such as data and literature). Scholix provides incentives and encourages best practice in the use of such identifiers and standardised referencing. The Data and Literature Interlinking Service (DLI: dliservice.research-infrastructures.eu) is the first exemplar of an aggregation and query service supported by the Scholix framework which will allow the emergence of third party services such as domain-specific aggregations, integrations with other global services, discovery tools, impact assessments, etc. Scholix is already implemented by existing hubs or global aggregators of data-literature link information such as DataCite, CrossRef, OpenAIRE, and EMBL-EBI building on the capacities of existing Persistent Identifier Systems (PIDs) such as Digital Object Identifiers (DOI) and Accession Numbers. These hubs in turn work with their natural communities of data centres or literature publishers to collect the information through

    To summarize the current evidence for adaptive servo ventilation (ASV) in Cheyne-Stokes respiration (CSR) with central sleep apnea (CSA) in heart failure (HF) and advance a research agenda and clinical considerations for ASV-treated CSR-CSA in HF. CSR-CSA in HF is associated with higher overall mortality, worse outcomes and lower quality of life (QOL) than HF without CSR-CSA. Five databases were searched using key words (n = 234). Randomized controlled trials assessed objective sleep quality, cardiac, and self-reported outcomes in adults (≥18 years) with HF (n = 10). ASV has a beneficial effect on the reduction of central sleep apnea in adult patients with CSR-CSA in HF, but it is not be superior to CPAP, bilevel PPV, or supplemental oxygen in terms of sleep quality defined by polysomnography, cardiovascular outcomes, subjective daytime sleepiness, and quality of life. ASV is not recommended for CSR-CSA in HF. It is important to continue to refer HF patients for sleep evaluation to clearly discern OSA from CSR-CSA. Symptom management research, inclusive of objective and subjective outcomes, in CSR-CSA in HF adults is needed.

    This paper explores the erosion and problematization of ‘the organization’ as a demarcated entity. Utilizing Foucault's reflections on ‘state-phobia’ as a source of inspiration, I show how an organization-phobia has gained a hold within Organization Theory (OT). By attending to the history...... of this organization-phobia, the paper argues that OT has become increasingly incapable of speaking about its core object. I show how organizations went from being conceptualized as entities of major importance to becoming theoretically deconstructed and associated with all kinds of ills. Through this history......, organizations as distinct entities have been rendered so problematic that they have gradually come to be removed from the center of OT. The costs of this have been rather significant. Besides undermining the grounds that gave OT intellectual credibility and legitimacy to begin with, the organization-phobia...

    Digital model-based engineering (DMbE) is the use of digital artifacts, digital environments, and digital tools in the performance of engineering functions. DMbE is intended to allow an organization to progress from documentation-based engineering methods to digital methods that may provide greater flexibility, agility, and efficiency. The term 'DMbE' was developed as part of an effort by the Model-Based Systems Engineering (MBSE) Infusion Task team to identify what government organizations might expect in the course of moving to or infusing MBSE into their organizations. The Task team was established by the Interagency Working Group on Engineering Complex Systems, an informal collaboration among government systems engineering organizations. This Technical Memorandum (TM) discusses the work of the MBSE Infusion Task team to date. The Task team identified prerequisites, expectations, initial challenges, and recommendations for areas of study to pursue, as well as examples of efforts already in progress. The team identified the following five expectations associated with DMbE infusion, discussed further in this TM: (1) Informed decision making through increased transparency, and greater insight. (2) Enhanced communication. (3) Increased understanding for greater flexibility/adaptability in design. (4) Increased confidence that the capability will perform as expected. (5) Increased efficiency. The team identified the following seven challenges an organization might encounter when looking to infuse DMbE: (1) Assessing value added to the organization. Not all DMbE practices will be applicable to every situation in every organization, and not all implementations will have positive results. (2) Overcoming organizational and cultural hurdles. (3) Adopting contractual practices and technical data management. (4) Redefining configuration management. The DMbE environment changes the range of configuration information to be managed to include performance and design models

This paper proposes a method for estimating scenario probabilities by combining the subjective and objective data. In this method, firstly, the history cases are screened according to the calculated similarity degree between history cases and the current emergency event. Then, the objective scenario probabilities are calculated according to the statistics of scenario of similar cases. Furthermore, the subjective scenario probabilities are estimated according to the weighted average result of expert judgments. Moreover, scenario probabilities are obtained by integrating the subjective and objective scenario probabilities. Finally, a numerical example is used to illustrate the feasibility and significance of the proposed method.

    2014-01-01

    Several work models for care improvement have been developed in order to meet the requirement for evidence-based care. This study examines a work model for reflection, entitled the reflective team (RT). The main idea behind RTs is that caring skills exist among those who work closest to the patients. The team leader (RTL) encourages sustainable care improvement, rooted in research and proven experience, by using a lifeworld perspective to stimulate further reflection and a developmental process leading to research-based caring actions within the team. In order to maintain focus, it is important that the RTL has a clear idea of what sustainable care improvement means, and what the prerequisites are for such improvement. The aim of the present study is, therefore, to explore the prerequisites for improving sustainable care, seeking to answer how RTLs perceive these and use RTs for concrete planning. Nine RTLs were interviewed, and their statements were phenomenographically analysed. The analysis revealed three separate qualitative categories, which describe personal, interpersonal, and structural aspects of the prerequisites. In the discussion, these categories are compared with previous research on reflection, and the conclusion is reached that the optimal conditions for RTs to work, when focussed on sustainable care improvement, occur when the various aspects of the prerequisites are intertwined and become a natural part of the reflective work.

    2007-01-01

    In order to design and provide good services, it is necessary for students to describe and understand the customer requirements for services rapidly, to design and plan the services and their behavior, and to schedule service processes effectively. This paper proposes a new service-oriented requirement elicitation and analysis method based on answer set semantic, sketches requirement Meta-model and correlative proofs and algorithms, which can help students represent requirement more declarative and precise. Based on the Meta-model, Subject-Predicate-Object requirement method and specification is presented, by which students can constitute a smooth, small-step, incremental and iterative development process cut in by forms. By applying this method to teach and help students develop service-oriented application, it is clear that it can help students eliminate the miscommunication between developers and users, assure the correctness of the artifacts and make the users active in development cycle.

Firstly based on steering by wire system, a steering force characteristics model with adjustable parameters is built for on-center steering, and with uniform experimental design technique, 12 differ-ent on-center steering force characteristics are analyzed, then on which a subjective evaluation is performed by eval-uators on driving simulator. Meanwhile, an objective evaluation is also carried out by off-line simulation according to the relevant international standards of ISO. Then the correlation between subjective evaluation items and objective e-valuation indicators is analyzed by applying multivariate linear regression method. The results show that the average relative error of subjective ratings predicted by the correlation established is less than 4%. Finally, the ideal values of key objective indicators are obtained based on the multivariate linear regression model built. The method proposed provides an effective guide to the development of steering system.

  15. The political economy of health promotion: part 1, national commitments to provision of the prerequisites of health.

    Science.gov (United States)

    Raphael, Dennis

    2013-03-01

    Canada is a leader in developing health promotion concepts of providing the prerequisites of health through health-promoting public policy. But Canada is clearly a laggard in implementing these concepts. In contrast, France is seen as a nation in which health promotion concepts have failed to gain much traction yet evidence exists that France does far better than Canada in providing these health prerequisites. Such findings suggest that it is the political economy--or form of the welfare state--of a nation rather than its explicit commitments to health promotion concepts--that shape provision of the prerequisites of health. Part 1 of this article examines how health promotion rhetoric specifically concerned with provision of the prerequisites of health differs among nations identified as being either liberal, social democratic, conservative or Latin welfare states. Governing authorities of nations that are liberal or social democratic welfare states are more likely to make explicit rhetorical commitments to provision of the prerequisites of health, the conservative and Latin states less so. Part 2 of this article provides evidence however, that despite their rhetorical commitments to provision of the prerequisites of health, liberal welfare state nations fall well behind not only the social democratic nations, but also the conservative welfare states in implementing public policies that provide the prerequisites of health. The Latin welfare states express little commitment to provision of the prerequisites of health and rather limited public policy activity towards meeting this aim.

The difference lies in the definition of“illeGal possession”,different financial fraud also required different“basic facts”of presumption,but the“basic facts”should have the normal connection and refutability of presumption. On the basis of the normal connection be_tween the“basic facts”and the“facts to be proved”,allow and ensure the refute riGht of the defendant,if he/she is unable to provide evidence or the evidence can’t make the judGe Generate any reasonable doubt at the“fact to be proved”,the presumption can be set up.%所有金融诈骗罪的共同点是都需要以客观推定主观,以非法占有目的为主观要件。不同点在于对“非法占有”的界定,对不同的金融诈骗所要求的推定之“基础事实”也应不同,但均应具备推定的常态联系性和可反驳性。在基础事实与待证事实间具有常态联系的基础上,允许并保障被告人的反驳权,如果其不能提供证据或提供的证据不能使法官对待证事实产生任何合理怀疑,方能认定推定成立。

    Basic calculus skills that are prerequisites for advanced mathematical studies continue to be a problem for a significant proportion of higher education students. While there are many types of revision material that could be offered to students, in this paper we investigate whether short, narrated video recordings of mathematical explanations (screencasts) are a useful tool to enhance student learning when revisiting prerequisite topics. We report on the outcomes of a study that was designed to both measure change in student performance before and after watching screencasts, and to capture students' perception of the usefulness of screencasts in their learning. Volunteers were recruited from students enrolled on an entry module for the Mathematics Master of Science programme at the Open University to watch two screencasts sandwiched between two online calculus quizzes. A statistical analysis of student responses to the quizzes shows that screencasts can have a positive effect on student performance. Further analysis of student feedback shows that student confidence was increased by watching the screencasts. Student views on the value of screencasts for their learning indicated that they appreciated being able to watch a problem being solved and explained by an experienced mathematician; hear the motivation for a particular problem-solving approach; engage more readily with the material being presented, thereby retaining it more easily. The positive student views and impact on student scores indicate that short screencasts could play a useful role in revising prerequisite mathematics.

    Full Text Available The aim of the paper is to investigate the preservation of written heritage in monastery libraries from legislative, institutional and organizational perspectives, and establish the necessary organizational prerequisites for improvement. Setting off from the presupposition that the library collections of monastery libraries are of immense cultural value, and can therefore be considered cultural good and part of Croatian written heritage, the paper discussed the need for a systematic approach to its protection, both on the operative level, in libraries themselves, and on the strategic level, by the authorities and other relevant institutions in the Republic of Croatia. In addition to the analysis of the legal and institutional frameworks and library collections preservation projects, three case studies were conducted in Franciscan monasteries in Mostar, Požega and Zadar, including interviews with their managers and one subject from the Croatian Institute of Librarianship. The case study aimed to investigate the context of the preservation of library collections in monastery libraries and provide answers to the following questions: how is the preservation in monastery libraries defined; how does it differ from the preservation in other libraries, and how is the preservation of collections in these libraries organized on institutional, local, and national levels? The research sets off from several core presuppositions: monastery libraries have valuable collections of Croatian and European written heritage; the heritage collections in monastery libraries are not investigated, organized, protected or presented at an adequate level; the responsibility for its preservation is not clearly assigned, there is not enough staff trained for preservation; the improvements in preservation and availability of library collections in monastery libraries should result from a better organization and management of the heritage preservation system in monastery

    China's Consumer Protection Law does not make a clear definition of the concept of consumer.From the incomplete "consume"concept in the dialysis of the object of consumption,subject of consumption and consumption purposes of the provisions is also biased,which led to confusion in the law enforcement and judicial areas for more than ten years.In this paper, combining the consumer relations and China's current consumption of the actual,the author tries to redetermine the above three areas,and wants to reach a breakthrough in the field of related concepts and innovations.Medical services,financial services and real estate transactions and other objects should belong to the expansion of the ranks of the consumer;consume subject includes not only the natural individual consumer,but also includes legal and other units;consumption is not limited to the purpose of consumption,also covers the production consumption.The above expansion should be important amendment of the Consumer Law,which is the only way to be more reasonable in the sense of achieving the purpose of consumer protection legislation.%我国《消费者权益保护法》并没有对“消费者”概念作出一个明确的定义,从这个不完整的“消费者”概念中透析出的消费客体、消费主体与消费目的三个方面的规定也有失偏颇,由此导致了十几年来的执法和司法领域的混乱。因此.要分别对以上三个方面予以重新厘定,在相关概念领域有所突破和创新。医疗服务、金融服务和商品房买卖等应属于消费客体扩张之行列:消费主体不仅包括自然人个体。还应包括法人等单位;消费目的不仅仅限于生活消费.还应涵盖生产消费。以上内涵性扩张应该是《消法》修订的重要内容,必须首先予以明确。唯有如此.才能在更加合理的意义上实现消费者权益保护的立法目的。

    Telenursing is an expanding part of healthcare, staffed with registered nurses whose work environment is typical of a call centre. Work-related stress has been shown to be a major problem in nurses' work environments and of importance to the outcome of care, patient safety, nurse job satisfaction and burnout. Today, however, we have a limited understanding of and knowledge about the work environment for telenurses. The aim of the present study is to explore and reach consensus on perceived important obstacles and prerequisites in telenurses' work environment. A modified Delphi design, using qualitative as well as quantitative data sequentially through three phases, was taken. Data were initially collected via semi-structured interviews (Phase I) and later using a web survey (Phase II-III) between March 2015 and March 2016. The findings present a consensus view of telenurses' experiences of important obstacles and prerequisites in their work environment. Central to the findings are the aspects of telenurses having a demanding work, cognitive fatigue and having no opportunity for recovery during the work shift was ranked as important obstacles. Highly ranked prerequisites for managing were being able to focus on one caller at a time, working in a calm and pleasant environment and having technical support 24/7. Managers need to enable telenurses to experience control in their work, provided with possibilities to control their work and to recover during work; shortening work time could improve their work environment. Limited possibilities to perform work might contribute to feelings of stress and inability to perform work.

    Full Text Available Introduction: Primary care organizations are the entities through which clinical governance is developed at local level. To implement clinical governance in primary care, awareness about principles, prerequisites and barriers of this quality improvement paradigm is necessary. The aim of this study is to pool evidence about implementing clinical governance in primary care organizations. Data sources: The literature search was conducted in July 2012. PubMed, Web of Science, Emerald, Springerlink, and MD Consult were searched using the following MESH keywords; “clinical governance” and “primary care” Study selection: The search was limited to English language journals with no time limitation. Articles that were either quantitative or qualitative on concepts of implementing clinical governance in primary care were eligible for this study. Data extraction: From selected articles, data on principles, prerequisites and barriers of clinical governance in primary health care were extracted and classified in the extraction tables. Results: We classified our findings about principles of clinical governance in primary care in four groups; general principles, principles related to staff, patient and communication. Prerequisites were categorized in eight clusters; same as the seven dimensions of National Health System (NHS models of clinical governance. Barriers were sorted out in five categories as structure and organizing, cultural, resource, theoretical and logistical. Conclusion: Primary care organizations must provide budget holding, incentivized programs, data feedback, peer review, education, human relations, health information technology (HIT support, and resources. Key elements include; enrolled populations, an interdisciplinary team approach, HIT interoperability and access between all providers as well as patients, devolution of hospital based services into the community, inter-sectorial integration, blended payments, and a balance of

    Full Text Available Problem statement: Artificial intelligence chatbot is a technology that makes interactions between man and machines using natural language possible. From literature, we found out that in general, chatbot are functions like a typical search engine. Although chatbot just produced only one output instead of multiple outputs/results, the basic process flow is the same where each time an input is entered, the new search will be done. Nothing related to previous output. This research is focused on enabling chatbot to become a search engine that can process the next search with the relation to the previous search output. In chatbot context, this functionality will enhance the capability of chatbot’s input processing. Approach: In attempt to augment the traditional mechanism of chatbot processes, we used the relational database model approach to redesign the architecture of chatbot in a whole as well as incorporated the algorithm of Extension and Prerequisite (our proposed algorithm.

    The work addresses the question of extending certain symplectic and exceptional Lie Symmetry groups to the realm of chaotic dynamics. Using a collection of simple examples, the technique of transfinite continuation is illustrated and various physically relevant results are obtained. The paper is intended as an elementary introduction to the use of symmetry groups in transfinite physics and as such is a sequel to a series of previous papers constituting the elementary and advanced mathematical prerequisite for a proper understanding of E-infinity theory.

    The diffusion of the impurities Cu, Ag, Au, and Na in CdTe and CdZnTe exhibits the unusual phenomenon of uphill diffusion if the diffusion of the impurity is performed under external Cd pressure at temperatures typically in the range 700-900 K. A model is proposed that describes these concentration profiles quantitatively and yields pre-requisites for the observation of uphill diffusion. If a metal layer is evaporated onto the implanted surface, the diffusion of the impurity is strongly affected by the generation of intrinsic defects at the metal-semiconductor interface.

    Standards of quality assurance according to DIN EN ISO 9001:2000 have been implemented in many university hospital departments, but often teaching activities are not included. This work presents a method that allows, after having defined the various teaching activities as sub-processes of one single core process, to include the manifold teaching activities of university hospital departments into the certification process. The stepwise description of the prerequisites for including teaching activities into ISO 9001 certification is illustrated by a concrete implementation example.

  1. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Directory of Open Access Journals (Sweden)

    Rashmika Pandya

    2011-02-01

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other. 

  2. Object-Interviews: Folding, Unfolding, and Refolding Perceptions of Objects

    Directory of Open Access Journals (Sweden)

    Susan Naomi Nordstrom PhD

    2013-02-01

    Full Text Available This article describes the object-interview as a Deleuzian space in which subjects and objects, living and nonliving, entangle together. I developed the object-interview to understand the connections that 11 Midwestern family history genealogists made between objects (e.g., documents, photographs, and other artifacts and their ancestors. The object-interview suggests an alternative way to think and do qualitative interviews informed by poststructural theories. The method draws on French philosopher Deleuze's concepts of the fold, events, and a life, as well as conventional qualitative interview literature. Deleuze's concepts offer a way to rethink objects and subjects as fibrous, connective, and folding entities in qualitative interviews. Such a rethinking offers an alternative to subject-centered conventional qualitative interviews in which subjects are teased apart from objects and subjects primarily produce knowledge. The object-interview, then, is a Deleuzian space in which the supposed distinctions between subjects and objects, as well as other binary divisions, become indistinct, or entangled, as both subjects and objects produce knowledge. That space enabled me to create the concept ensemble of life—a constantly shifting group of objects associated with a person's life. In this article, I describe the theoretical entanglement of the object-interview, the object-interview itself, the data it produced in my dissertation study, and the significance of the method to the field of qualitative research methods.

  3. Object crowding.

    Wallace, Julian M; Tjan, Bosco S

    2011-05-25

    Crowding occurs when stimuli in the peripheral fields become harder to identify when flanked by other items. This phenomenon has been demonstrated extensively with simple patterns (e.g., Gabors and letters). Here, we characterize crowding for everyday objects. We presented three-item arrays of objects and letters, arranged radially and tangentially in the lower visual field. Observers identified the central target, and we measured contrast energy thresholds as a function of target-to-flanker spacing. Object crowding was similar to letter crowding in spatial extent but was much weaker. The average elevation in threshold contrast energy was in the order of 1 log unit for objects as compared to 2 log units for letters and silhouette objects. Furthermore, we examined whether the exterior and interior features of an object are differentially affected by crowding. We used a circular aperture to present or exclude the object interior. Critical spacings for these aperture and "donut" objects were similar to those of intact objects. Taken together, these findings suggest that crowding between letters and objects are essentially due to the same mechanism, which affects equally the interior and exterior features of an object. However, for objects defined with varying shades of gray, it is much easier to overcome crowding by increasing contrast.

    Good manufacturing practices (GMP) and sanitation standard operating procedures (SSOP) are prerequisites programs for the application of the Hazard Analysis and Critical Control Point (HACCP) system as a food safety approach during processing. The aim of this study was to evaluate GMP/SSOP prerequisites in processing line of frozen whole sardine (Sardinella aurita). The GMP compliance was verified according to a standard procedure of the Ministry for the Health of Venezuela, and the SSOP were assessed according to a checklist proposed by the FDA. GMP and SSOP were evaluated following a demerit-based approach. A percentage value was calculated and referred to as sanitary effectiveness. Results indicated that the plant had a good level of compliance with GMP from assessment of buildings and facilities, equipment and tools, hygienic requisites of the production, assurance of the hygiene quality, storage and transportation, and the percentage of sanitary effectiveness was 84%. The level of compliance for SSOP was 53,12% with demerits found in all assessed aspects consisting of inexistent guidelines, lack of control in the sanitary plan and lack of leadership in applying corrective actions. Thus, an improvement in the plant sanitation program was designed targeting SSOP.

  6. A method for assessing required course-related skills and prerequisite structure

    2015-05-01

    Engineering curricula should be dynamic with a goal of constant improvement and refinement. Unfortunately, this is often not the case; courses are developed, altered, and expanded in a piecemeal manner. Namely, as time progresses many programmes end up with courses that are developed and not a developed curriculum. To remedy this shortcoming product, development tools are proposed for the refinement and assessment of an existing curriculum; how these methods could be used for the development of a curriculum is also highlighted. The voice of the customer (VOC) process is used to identify and prioritise desired student skills. The design structure matrix (DSM) is used to assess course prerequisite structure. There is broad agreement between faculty and industry related to which professional skills are the most important. The DSM is shown to be a useful tool in ordering courses and assessing prerequisite structures. The DSM is also shown to be useful in identifying which courses in a curriculum are critical and should be the focus of educational and administrative resources.

    Full Text Available The aim of the article is to study principles, economic and institutional prerequisites for fiscal decentralization on post-conflict territories. It is determined that fiscal decentralization is one of the main ways to solve problems of post-conflict areas. There justified principles, economic and institutional prerequisites of fiscal decentralization on post-conflict territories with regard to the specificity of individual spheres of fiscal relations. Moreover, different spheres of fiscal relations require different approaches: the sphere of public revenues — providing economic efficiency with the formation of the tax structure contributing to the expansion of the tax base; the sphere of public spending — ensuring social justice and transparency in allocation of social cost at the local level; the sphere of subsidies — narrowing the scope of application of intergovernmental transfers with organizing the redistribution of financial resources under the principle of «center - post-conflict regions - post-conflict recipients»; the sphere of external assistance — ensuring proper coordination for cultivation of new co-operative institutions.

    Full Text Available South African organisations must undergo a mind shift and adhere to certain prerequisites to survive and be successful. It is evident that companies not changing their mindsets will not survive and be able to create a sustainable competitive advantage and to compete in world markets. Companies have to solve new problems with new paradigms, constantly create something better, something new, create new markets as opposed to increasing market share. The Third Wave development will lead to societal transformation. Moving to Third Wave will imply growth organisations to act like small entrepreneurial businesses that will have the benefit of speed and simplicity but also be able to implement strategy more effectively. Time is of the essence. South African companies have no other option but to move swiftly. The transformation from second to third wave is inevitable.

  15. Controlled assembly: a prerequisite for the use of recombinant spider silk in regenerative medicine?

    Science.gov (United States)

    Rising, Anna

    2014-04-01

    Recent biotechnological progress has enabled the production of spider silk proteins, spidroins, in heterologous hosts. Matrices based on recombinant spidroins support stem cell growth and are well tolerated when implanted in living tissue, thus the material is highly attractive for use in regenerative medicine. However, the matrices made are far from natural silk in terms of mechanical properties and are either spontaneously assembled, which results in heterogeneous products, or spun from harsh solvents with the concomitant risk of harmful remnants in the final products. If we could mimic the spider's aqueous silk spinning process we would likely obtain a material that had reproducible and better characteristics and that more easily could be transferred to clinical practice. Herein, the knowledge of the spiders' silk production system and the prerequisites for artificial spinning and assembly of recombinant proteins are reviewed and discussed in a biomedical context.

  1. Rediscovering psychopathology: the epistemology and phenomenology of the psychiatric object.

    Science.gov (United States)

    Parnas, Josef; Sass, Louis A; Zahavi, Dan

    2013-03-01

    Questions concerning both the ontology and epistemology of the "psychiatric object" (symptoms and signs) should be at the forefront of current concerns of psychiatry as a clinical neuroscience. We argue that neglect of these issues is a crucial source of the stagnation of psychiatric research. In honor of the centenary of Karl Jaspers' book, General Psychopathology, we offer a critique of the contemporary "operationalist" epistemology, a critique that is consistent with Jaspers' views. Symptoms and signs cannot be properly understood or identified apart from an appreciation of the nature of consciousness or subjectivity, which in turn cannot be treated as a collection of thing-like, mutually independent objects, accessible to context-free, "atheoretical" definitions or unproblematic forms of measurement (as is often assumed in structured interviewing). Adequate and faithful distinctions in the phenomenal or experiential realm are therefore a fundamental prerequisite for classification, treatment, and research. This requires a multidisciplinary approach, incorporating (among other things) insights provided by psychology, phenomenological philosophy, and the philosophy of mind.

    2006-01-01

    This paper discusses the single-machine rescheduling problem with efficiency and stability as criteria, where more than one disruption arises in large-scale dynamic circumstances. Partial rescheduling (PR) strategy is adopted after each disruption and a rolling mechanism is driven by events in response to disruptions. Two kinds of objective functions are designed respectively for PR sub-problem involving in the interim and the terminal of unfinished jobs. The analytical result demonstrates that each local objective is consistent with the global one. Extensive computational experiment was performed and the computational results show that the rolling PR strategy with dual objectives can greatly improve schedule stability with little sacrifice in efficiency and provide a reasonable trade-off between solution quality and computational efforts.

    Full Text Available In the growing body of marketing literature on the impact of consumer knowledge on intention to buy, distinction between subjective and objective knowledge has clearly been made. The difference between subjective and objective knowledge may be due to both the definition and measurement process. The goal of this research is to examine the impact of both subjective and objective knowledge related to attitude to and intention to buy light milk and dairy products. Data were gathered via face-to-face survey from 330 consumers living in Erdemli district of Mersin, Turkey. A Hybrid Path Analysis was performed to test the hypothesis. The results of Structural Equations Modelling clearly indicate that subjective knowledge and health consciousness are positively associated with attitude towards light milk and dairy products and objective knowledge is negatively associated with attitude towards light milk and dairy products. Also, attitude towards light milk and dairy products is positively associated with intention to buy these products. Implications and suggestions are developed based on the structural model for future researches.

    Skow, Bradford

    2015-01-01

    Bradford Skow presents an original defense of the 'block universe' theory of time, often said to be a theory according to which time does not pass. Along the way, he provides in-depth discussions of alternative theories of time, including those in which there is 'robust passage' of time or 'objective becoming': presentism, the moving spotlight theory of time, the growing block theory of time, and the 'branching time' theory of time. Skow explains why the moving spotlight theory is the best of these arguments, and rebuts several popular arguments against the thesis that time passes. He surveys the problems that the special theory of relativity has been thought to raise for objective becoming, and suggests ways in which fans of objective becoming may reconcile their view with relativistic physics. The last third of the book aims to clarify and evaluate the argument that we should believe that time passes because, somehow, the passage of time is given to us in experience. He isolates three separate arguments thi...

    2007-06-01

    Subtle interaction between shape-memory polymer and cellulose fibers within fabrics remains a critical issue for understanding their thermal-mechanical properties and thus the shape-memory behavior in cotton fibers. We demonstrate here the efficacy of Raman spectroscopy to probe the induced stresses in warp and weft fibers, presenting physicochemical features for cellulose fibers finished with macromolecule polyurethane and small-molecule dimethyloldihydroxyethyleneurea. Accordingly, a possible mechanism for transfer of the shape-memory effect to fabrics is proposed. Forming as a coating on the fiber surface after the finishing process, the shape-memory polymer takes a critical role in reducing the residual stress in weft fibers, establishing the prerequisite for reserving the shape-memory effect to fabric. In addition, this work has demonstrated that Raman spectroscopy is able to probe the residual stresses in cotton fabrics after being treated by chemicals in addition to that due to physical deformation. Our result provides clear evidence that in the finishing process strength reduction in fibers in general is not only caused solely by a chemical reaction, but also by a physical modification of the cotton structure.

We observed, by immunohistochemistry, dynamic changes of nuclear β-catenin in the CM and RPE after injury (retinectomy. β-Catenin nuclear accumulation was transiently lost in cells of the CM in response to injury alone, while the loss of nuclear β-catenin was maintained as long as FGF2 was present. However, nuclear β-catenin positive cells remained in the RPE in response to injury and were BrdU-/p27+, suggesting that nuclear β-catenin prevents those cells from entering the cell cycle. If FGF2 is present, the RPE undergoes dedifferentiation and proliferation concomitant with loss of nuclear β-catenin. Moreover, retinectomy followed by disruption of active β-catenin by using a signaling inhibitor (XAV939 or over-expressing a dominant negative form of Lef-1 induces regeneration from both the CM and RPE in the absence of FGF2. Our results imply that β-catenin protects cells of the CM and RPE from entering the cell cycle in the developing eye, and specifically for the RPE during injury. Thus inactivation of β-catenin is a pre-requisite for chick retina regeneration.

    A characteristic feature of the life activity of modern children and adolescents is the couch potato, mostly "sedentary" lifestyle. Biomedical and psychosocial significance of motor activity (MA) stipulates the necessity of the substantiation of scientific and methodological approaches to the formation of the motivation to exercises and sports in children. The purpose of the study was in the scientific substantiation and the delivery of medical, pedagogical and neurophysiological prerequisites for the formation of the motivation to increase MA in students in current conditions of their life activity. There were examined 189 students from 2-5th and 9th classes, out of them 65 students were observed in the dynamics of the school year; 585 students from the 1st-11th classes participated in the survey. Results of the study allowed to reveal the relation of students to the lessons of physical training, to evaluate the impact of a new educational program on the functional possibilities of the body of children from the special medical group "A" and to reveal the neurophysiological features of adolescents with different needs in motion.

  13. Understanding entangled cerebral networks: A prerequisite for restoring brain function with brain-computer interfaces

    Full Text Available Historically, cerebral processing has been conceptualized as a framework based on statically localized functions. However, a growing amount of evidence supports a hodotopical (delocalized and flexible organization. A number of studies have reported absence of a permanent neurological deficit after massive surgical resections of eloquent brain tissue. These results highlight the tremendous plastic potential of the brain. Understanding anatomo-functional correlates underlying this cerebral reorganization is a prerequisite to restore brain functions through brain-computer interfaces (BCIs in patients with cerebral diseases, or even to potentiate brain functions in healthy individuals. Here, we review current knowledge of neural networks that could be utilized in the BCIs that enable movements and language. To this end, intraoperative electrical stimulation in awake patients provides valuable information on the cerebral functional maps, their connectomics and plasticity. Overall, these studies indicate that the complex cerebral circuitry that underpins interactions between action, cognition and behavior should be throughly investigated before progress in BCI approaches can be achieved.

  14. Neuroinflammation is not a prerequisite for diabetes-induced tau phosphorylation

    Full Text Available Abnormal phosphorylation and aggregation of tau is a key hallmark of Alzheimer's disease (AD. AD is a multifactorial neurodegenerative disorder for which Diabetes Mellitus (DM is a risk factor. In animal models for DM, the phosphorylation and aggregation of tau is induced or exacerbated, however the underlying mechanism is unknown. In addition to the metabolic dysfunction, DM is characterized by chronic low-grade inflammation. This was reported to be associated with a neuroinflammatory response in the hypothalamus of DM animal models. Neuroinflammation is also implicated in the development and progression of AD. It is unknown whether DM also induces neuroinflammation in brain areas affected in AD, the cortex and hippocampus. Here we investigated whether neuroinflammation could be the mechanistic trigger to induce tau phosphorylation in the brain of DM animals. Two distinct diabetic animal models were used; rats on free-choice high-fat high-sugar (fcHFHS diet that are insulin resistant and streptozotocin-treated rats that are insulin deficient. The streptozotocin-treated animals demonstrated increased tau phosphorylation in the brain as expected, whereas the fcHFHS diet fed animals did not. Remarkably, neither of the diabetic animal models showed reactive microglia or increased GFAP and COX-2 levels in the cortex or hippocampus. From this, we conclude: 1. DM does not induce neuroinflammation in brain regions affected in AD, and 2. Neuroinflammation is not a prerequisite for tau phosphorylation. Neuroinflammation is therefore not the mechanism that explains the close connection between DM and AD.

  15. Trisomy 21- affected placentas highlight prerequisite factors for human trophoblast fusion and differentiation.

    Trophoblastic cell fusion is one essential step of the human trophoblast differentiation pathway and is a multifactorial and dynamic process finely regulated and still poorly known. Disturbances of syncytiotrophoblast formation are observed in numerous pathological clinical conditions such as preeclampsia, intrauterine growth retardation and trisomy 21. In this review, we summarize current knowledge of the different membrane proteins directly involved in trophoblastic cell fusion, which we identified by using the physiological model of primary culture of villous trophoblastic cells. Connexin 43 and gap junctional intercellular communication point to the role of molecular exchanges through connexin channels preceding membrane fusion. Zona occludens-1, which can interact with connexin 43, is also directly involved in trophoblast fusion. The recently identified fusogenic membrane retroviral envelop glycoproteins syncytin 1 (encoded by the HERV-W gene) and syncytin 2 (encoded by the FRD gene) and their receptors are major factors involved in human placental development . We describe the increasing number of factors promoting or inhibiting trophoblast fusion and differentiation and emphasize the role of human chorionic gonadotropin (hCG) and its receptor. Indeed, in trisomy 21 the dynamic process leading to membrane fusion is impaired due to an abnormal hCG signaling. This abnormal trophoblast fusion and differentiation in trisomy 21-affected placenta is reversible in vitro. Trisomy 21 trophoblastic cell culture may therefore be useful to identify the possible large number of prerequisite factors involved in trophoblast fusion, the limiting step of trophoblast differentiation.

  16. Are left fronto-temporal brain areas a prerequisite for normal music-syntactic processing?

    An increasing number of neuroimaging studies in music cognition research suggest that "language areas" are involved in the processing of musical syntax, but none of these studies clarified whether these areas are a prerequisite for normal syntax processing in music. The present electrophysiological experiment tested whether patients with lesions in Broca's area (N=6) or in the left anterior temporal lobe (N=7) exhibit deficits in the processing of structure in music compared to matched healthy controls (N=13). A chord sequence paradigm was applied, and the amplitude and scalp topography of the Early Right Anterior Negativity (ERAN) was examined, an electrophysiological marker of musical syntax processing that correlates with activity in Broca's area and its right hemisphere homotope. Left inferior frontal gyrus (IFG) (but not anterior superior temporal gyrus - aSTG) patients with lesions older than 4 years showed an ERAN with abnormal scalp distribution, and subtle behavioural deficits in detecting music-syntactic irregularities. In one IFG patient tested 7 months post-stroke, the ERAN was extinguished and the behavioural performance remained at chance level. These combined results suggest that the left IFG, known to be crucial for syntax processing in language, plays also a functional role in the processing of musical syntax. Hence, the present findings are consistent with the notion that Broca's area supports the processing of syntax in a rather domain-general way.

    Mutations in RPE65, a gene essential to normal operation of the visual (retinoid) cycle, cause the childhood blindness known as Leber congenital amaurosis (LCA). Retinal gene therapy restores vision to blind canine and murine models of LCA. Gene therapy in blind humans with LCA from RPE65 mutations may also have potential for success but only if the retinal photoreceptor layer is intact, as in the early-disease stage-treated animals. Here, we use high-resolution in vivo microscopy to quantify photoreceptor layer thickness in the human disease to define the relationship of retinal structure to vision and determine the potential for gene therapy success. The normally cone photoreceptor-rich central retina and rod-rich regions were studied. Despite severely reduced cone vision, many RPE65-mutant retinas had near-normal central microstructure. Absent rod vision was associated with a detectable but thinned photoreceptor layer. We asked whether abnormally thinned RPE65-mutant retina with photoreceptor loss would respond to treatment. Gene therapy in Rpe65(-/-) mice at advanced-disease stages, a more faithful mimic of the humans we studied, showed success but only in animals with better-preserved photoreceptor structure. The results indicate that identifying and then targeting retinal locations with retained photoreceptors will be a prerequisite for successful gene therapy in humans with RPE65 mutations and in other retinal degenerative disorders now moving from proof-of-concept studies toward clinical trials.

  18. Positive Prerequisites for the Use of Reliefs in the Payment of Dues on Social Insurance Contributions

    Directory of Open Access Journals (Sweden)

    Zbigniew Ofiarski

    2014-06-01

    Full Text Available It is permissible to use reliefs in the payment of social security contributions, based either on a definitive waiver by the creditor of the whole or relevant part of the amount due (partial or complete remission or only a temporary waiver of such amounts (payment deferral or payment in installments. The use of such reliefs is possible upon the occurrence of conditions laid down in the Act, for example, in the case of total non-recovery of contributions, for economic or other reasons worth considering, if justified by important interests of the person concerned. The prerequisites mentioned above have a nature of general clauses, allowing for their flexible adjustment to specific situations. Entities authorized to grant reliefs in the payment of social security contributions act within the limits of administrative discretion. But it is not a fully free operation, because the economic impact resulting from the use of such reliefs has a direct impact on the financial balance of earmarked funds which finance social security benefits, in particular pensions, disability allowances and other benefits.

  19. Comparative Analysis on Romanian Taxation in the European Context, as a Prerequisite for Tax Harmonization

    2011-08-01

    Full Text Available The issue of tax harmonization at EU level is becoming more present in the global crisis context, as it is both accepted and disputed by the European officials that manifest their preference for either coordination or tax competition. The crisis has generated, among other things, large budget deficits and a dangerous crisis of debts in the euro area, a situation that has attracted many followers in terms of tax harmonization. There is a European regulated Area, a unique European market, European unique currency and common monetary policy which regard the criteria relating to public finances (budget deficits, public debt. We ask ourselves to what extent it is necessary to achieve coordination or even tax unification and how does that help. This paper examines, according to the statistical database, the level and type of taxation, on categories of taxes and as a share of GDP, in Romania compared to EU countries, in order to clarify the current situation, the existing differences, the prospect of good European practice. If we speak of tax harmonization in terms of being acquired by Romania, the conclusion is that we can not report only to the technical or quantifiable aspects, as compared with the best results in European area, because they do not represent a guarantee of similar results. The fiscal policy must be both a prerequisite and a consequence of sustainable economic and financial policies, and the tax harmonization can only help insofar as it relates to the relationships between states and not at the tax level.

    Full Text Available Focussing on the consideration of the multivariate relationship between sport and economics, the present study is based on the sport potential of supporting economic growth through the enhancement of the relatively new domain of “sport entrepreneurship”. The brief revision of the specialized literature regarding the development of sport entrepreneurship in general terms is followed by a series of fundamental factors for the innovative proposal of a sport entrepreneurship index (SEI in the European Union member countries. The methodological issues concerning the structure of the index represent the main novelty aspect of this research, which aims to be a prerequisite of a future thorough analysis regarding the micro- and macro-economic implications of developing a sport entrepreneurship index (SEI in EU countries. The main identified challenge is a scientific one and it resides in the summative assessment of the elements representing entrepreneurship, sport and culture in the SEI, whereas the necessity of determining such an index appears because of economic and social reasons.

    Full Text Available Time series data from the capital market exhibits certain qualities which invalidate the hypotheses necessary for obtaining meaningful results from statistical modeling. This paper presents some of these qualities by looking at the time series for prices and returns on the Romanian Stock Exchange. The examples are based on the price time series and return time series of the Antibiotice securities and the BET-C index. The choice of a certain security and of the stock exchange index has been made with the intention of analyzing, in the future, the correlation between these two variables, and drawing significant conclusions which can be used for forecasts.Firstly, we will identify the empirical proprieties of the capital market, as they are described in the field research. Secondly, we will investigate the prerequisites for modeling chronological data series; these are stationary mean and variance. In the paper, the three methods are used: graphical representation, autocorrelation and the ADF test (Augmented Dickey-Fuller. For the frequent cases where the mean is not stationary, we will present the time series differentiation method, which can be used to obtain stationary values.Lastly, we will investigate the normality of the time series through the skewness and kurtosis methods, and through the Jarque-Bera statistic. We find out a characteristic for the capital market, in that the majority of the time series for securities have non-normal distributions.

    Full Text Available In all psychological tests, scoring should be of concern for examiners because the accuracy of results depends, at some extent, on the quality of the correction. This work aims to examine the correction, by different psychologists, of the scores for the Wechsler Intelligence Scale for Children (WISC-III subtests of Similarities, Vocabulary and Comprehension since these are the subtests where examiner's subjectivity seemingly most influences scoring. Forty two psychologists from different states in Brazil participated in this study. They corrected the answers of six test protocols randomly selected from a standardization sample for the Brazilian context. Taking as reference the total scores, the Vocabulary subtest showed greater variability in score, followed by the Comprehension one. Considering the total number of items tested in each subtest, Similarities had the highest agreement among raters. The results showed that all the three subtests involve subjectivity on behalf of the examiner to score the answers. Continuing in this study, we also aim to determine test reliability based on interrater agreement.

    The relevance of current standard medical school science prerequisites is being reexamined. (1) To identify which science prerequisites are perceived to best prepare osteopathic medical students for their basic science and osteopathic manipulative medicine (OMM) coursework and (2) to determine whether science prerequisites for osteopathic medical school should be modified. Preclinical osteopathic medical students and their basic science and OMM faculty from 3 colleges of osteopathic medicine were surveyed about the importance of specific science concepts, laboratories, and research techniques to medical school coursework. Participants chose responses on a 5-point scale, with 1 indicating "strongly disagree" or "not important" and 5 indicating "strongly agree" or "extremely important." Participants were also surveryed on possible prerequisite modifications. Student responses (N=264) to the general statement regarding prerequisites were "neutral" for basic science coursework and "disagree" for OMM coursework, with mean (standard deviation [SD]) scores of 3.37 (1.1) and 2.68 (1.2), respectively. Faculty responses (N=49) were similar, with mean (SD) scores of 3.18 (1.1) for basic science coursework and 2.67 (1.2) for OMM coursework. Student mean (SD) scores were highest for general biology for basic science coursework (3.93 [1.1]) and physics for OMM coursework (2.5 [1.1]). Student mean (SD) scores were lowest for physics for basic science coursework (1.79 [1.2]) and organic chemistry for OMM coursework (1.2 [0.7]). Both basic science and OMM faculty rated general biology highest in importance (mean [SD] scores, 3.73 [0.9] and 4.22 [1.0], respectively). Students and faculty rated biochemistry high in importance for basic science coursework (mean [SD] scores of 3.66 [1.2] and 3.32 [1.2], respectively). For basic science coursework, students and faculty rated most laboratories as "important," with the highest mean (SD) ratings for general anatomy (students, 3.66 [1

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

  9. Objective thermomechanics

    CERN Document Server

    Fülöp, Tamás

    2015-01-01

    An irreversible thermodynamical theory of solids is presented where the kinematic quantities are defined in an automatically objective way. Namely, auxiliary elements like reference frame, reference time and reference configuration are avoided by formulating the motion of the continuum on spacetime directly, utilizing the Weyl-Matolcsi description of spacetime. This restricts the range of definable kinematic quantities heavily. Solids are distinguished from fluids by possessing not only an instantaneous metric tensor but a relaxed metric, too, that represents the natural geometric structure of the solid. The comparison of the instantaneous metric to the relaxed one is the basis of the definition of the elastic state variable, the elastic deformedness tensor. Thermal expansion is conceived as the temperature dependence of the relaxed metric. As opposed to this reversible type of change, plasticity means an irreversible change in the relaxed metric, and is describable via a plastic change rate tensor. The relat...

    In recent years, laser-based acceleration of charged particles has rapidly progressed and medical applications, e.g., in radiotherapy, might become feasible in the coming decade. Requirements are monoenergetic particle beams with long-term stable and reproducible properties as well as sufficient particle intensities and a controlled delivery of prescribed doses at the treatment site. Although conventional and laser-based particle accelerators will administer the same dose to the patient, their different time structures could result in different radiobiological properties. Therefore, the biological response to the ultrashort pulse durations and the resulting high peak dose rates of these particle beams have to be investigated. The technical prerequisites, i.e., a suitable cell irradiation setup and the precise dosimetric characterization of a laser-based particle accelerator, have to be realized in order to prepare systematic cell irradiation experiments. The Jena titanium:sapphire laser system (JETI) was customized in preparation for cell irradiation experiments with laser-accelerated electrons. The delivered electron beam was optimized with regard to its spectrum, diameter, dose rate, and dose homogeneity. A custom-designed beam and dose monitoring system, consisting of a Roos ionization chamber, a Faraday cup, and EBT-1 dosimetry films, enables real-time monitoring of irradiation experiments and precise determination of the dose delivered to the cells. Finally, as proof-of-principle experiment cell samples were irradiated using this setup. Laser-accelerated electron beams, appropriate for in vitro radiobiological experiments, were generated with a laser shot frequency of 2.5 Hz and a pulse length of 80 fs. After laser acceleration in the helium gas jet, the electrons were filtered by a magnet, released from the vacuum target chamber, and propagated in air for a distance of 220 mm. Within this distance a lead collimator (aperture of 35 mm) was introduced, leading

  11. Intravirion cohesion of matrix protein M1 with ribonucleocapsid is a prerequisite of influenza virus infectivity.

    Influenza virus has two major structural modules, an external lipid envelope and an internal ribonucleocapsid containing the genomic RNA in the form of the ribonucleoprotein (RNP) complex, both of which are interlinked by the matrix protein M1. Here we studied M1-RNP cohesion within virus exposed to acidic pH in vitro. The effect of acidification was dependent on the cleavage of the surface glycoprotein HA. Acidic pH caused a loss of intravirion RNP-M1 cohesion and activated RNP polymerase activity in virus with cleaved HA (HA1/2) but not in the uncleaved (HA0) virus. The in vitro acidified HA1/2 virus rapidly lost infectivity whereas the HA0 one retained infectivity, following activation by trypsin, suggesting that premature activation and release of the RNP is detrimental to viral infectivity. Rimantadine, an inhibitor of the M2 ion channel, was found to protect the HA1/2 virus interior against acidic disintegration, confirming that M2-dependent proton translocation is essential for the intravirion RNP release and suggesting that the M2 ion channel is only active in virions with cleaved HA. Acidic treatment of both HA0 and HA1/2 influenza viruses induces formation of spikeless bleb-like protrusion of ~ 25 nm in diameter on the surface of the virion, though only the HA1/2 virus was permeable to protons and permitted RNP release. It is likely that this bleb corresponds to the M2-enriched and M1-depleted focus arising from pinching off of the virus during the completion of budding. Cooperatively, the data suggest that the influenza virus has an asymmetric structure where the M1-mediated organization of the RNP inside the virion is a prerequisite for infectious entry into target cell.

  12. Loss of PSD-95 enrichment is not a prerequisite for spine retraction.

    Changes in neuronal structure are thought to underlie long-term behavioral modifications associated with learning and memory. In particular, considerable evidence implicates the destabilization and retraction of dendritic spines along with the loss of spine synapses as an important cellular mechanism for refining brain circuits, yet the molecular mechanisms regulating spine elimination remain ill-defined. The postsynaptic density protein, PSD-95, is highly enriched in dendritic spines and has been associated with spine stability. Because spines with low levels of PSD-95 are more dynamic, and the recruitment of PSD-95 to nascent spines has been associated with spine stabilization, we hypothesized that loss of PSD-95 enrichment would be a prerequisite for spine retraction. To test this hypothesis, we used dual-color time-lapse two-photon microscopy to monitor rat hippocampal pyramidal neurons cotransfected with PSD-95-GFP and DsRed-Express, and we analyzed the relationship between PSD-95-GFP enrichment and spine morphological changes. Consistent with our hypothesis, we found that the majority of spines that retracted were relatively unenriched for PSD-95-GFP. However, in the subset of PSD-95-GFP-enriched spines that retracted, spine shrinkage and loss of PSD-95-GFP were tightly coupled, suggesting that loss of PSD-95-GFP enrichment did not precede spine retraction. Moreover, we found that, in some instances, spine retraction resulted in a significant enrichment of PSD-95-GFP on the dendritic shaft. Our data support a model of spine retraction in which loss of PSD-95 enrichment is not required prior to the destabilization of spines.

    The Prairie Pothole Region (PPR) contains ecosystems that are typified by an extensive matrix of grasslands and depressional wetlands, which provide numerous ecosystem services. Over the past 150 years the PPR has experienced numerous landscape modifications resulting in agricultural conversion of 75–99 % of native prairie uplands and drainage of 50–90 % of wetlands. There is concern over how and where conservation dollars should be spent within the PPR to protect and restore wetland basins to support waterbird populations that will be robust to a changing climate. However, while hydrological impacts of landscape modifications appear substantial, they are still poorly understood. Previous modeling efforts addressing impacts of climate change on PPR wetlands have yet to fully incorporate interacting or potentially overshadowing impacts of landscape modification. We outlined several information needs for building more informative models to predict climate change effects on PPR wetlands. We reviewed how landscape modification influences wetland hydrology and present a conceptual model to describe how modified wetlands might respond to climate variability. We note that current climate projections do not incorporate cyclical variability in climate between wet and dry periods even though such dynamics have shaped the hydrology and ecology of PPR wetlands. We conclude that there are at least three prerequisite steps to making meaningful predictions about effects of climate change on PPR wetlands. Those evident to us are: 1) an understanding of how physical and watershed characteristics of wetland basins of similar hydroperiods vary across temperature and moisture gradients; 2) a mechanistic understanding of how wetlands respond to climate across a gradient of anthropogenic modifications; and 3) improved climate projections for the PPR that can meaningfully represent potential changes in climate variability including intensity and duration of wet and dry periods.

    Full Text Available Introduction: Identifying appropriate pre-exposure prophylaxis (PrEP candidates is a challenge in planning for the safe and effective roll-out of this strategy. We explored the use of a validated HIV risk screening tool, HIV Incidence Risk Index for Men who have Sex with Men (HIRI-MSM, to identify “optimal” candidates among MSM testing at a busy sexual health clinic's community testing sites in Toronto, Canada. Methods: Between November 2014 and April 2015, we surveyed MSM undergoing anonymous HIV testing at community testing sites in Toronto, Canada, to quantify “optimal” candidates for scaling up PrEP roll-out, defined as being at high objective HIV risk (scoring ≥10 on the HIRI-MSM, perceiving oneself at moderate-to-high HIV risk and being willing to use PrEP. Cascades were constructed to identify barriers to broader PrEP uptake. The association between HIRI-MSM score and both willingness to use PrEP and perceived HIV risk were explored in separate multivariable logistic regression analyses. Results: Of 420 respondents, 64.4% were objectively at high risk, 52.5% were willing to use PrEP and 27.2% perceived themselves at moderate-to-high HIV risk. Only 16.4% were “optimal” candidates. Higher HIRI-MSM scores were positively associated with both willingness to use PrEP (aOR=1.7 per 10 score increase, 95%CI=1.3–2.2 and moderate-to-high perceived HIV risk (aOR=1.7 per 10 score increase, 95%CI=1.2–2.3. The proportion of men who were “optimal” candidates increased to 42.9% when the objective HIV risk cut-off was changed to top quartile of HIRI-MSM scores (≥26. In our full cascade, a very low proportion (5.3% of MSM surveyed could potentially benefit from PrEP under current conditions. The greatest barrier in the cascade was low perception of HIV risk among high-risk men, but considerable numbers were also lost in downstream cascade steps. Of men at high objective HIV risk, 68.3% did not perceive themselves to be at moderate

    Identifying appropriate pre-exposure prophylaxis (PrEP) candidates is a challenge in planning for the safe and effective roll-out of this strategy. We explored the use of a validated HIV risk screening tool, HIV Incidence Risk Index for Men who have Sex with Men (HIRI-MSM), to identify "optimal" candidates among MSM testing at a busy sexual health clinic's community testing sites in Toronto, Canada. Between November 2014 and April 2015, we surveyed MSM undergoing anonymous HIV testing at community testing sites in Toronto, Canada, to quantify "optimal" candidates for scaling up PrEP roll-out, defined as being at high objective HIV risk (scoring ≥10 on the HIRI-MSM), perceiving oneself at moderate-to-high HIV risk and being willing to use PrEP. Cascades were constructed to identify barriers to broader PrEP uptake. The association between HIRI-MSM score and both willingness to use PrEP and perceived HIV risk were explored in separate multivariable logistic regression analyses. Of 420 respondents, 64.4% were objectively at high risk, 52.5% were willing to use PrEP and 27.2% perceived themselves at moderate-to-high HIV risk. Only 16.4% were "optimal" candidates. Higher HIRI-MSM scores were positively associated with both willingness to use PrEP (aOR=1.7 per 10 score increase, 95%CI=1.3-2.2) and moderate-to-high perceived HIV risk (aOR=1.7 per 10 score increase, 95%CI=1.2-2.3). The proportion of men who were "optimal" candidates increased to 42.9% when the objective HIV risk cut-off was changed to top quartile of HIRI-MSM scores (≥26). In our full cascade, a very low proportion (5.3%) of MSM surveyed could potentially benefit from PrEP under current conditions. The greatest barrier in the cascade was low perception of HIV risk among high-risk men, but considerable numbers were also lost in downstream cascade steps. Of men at high objective HIV risk, 68.3% did not perceive themselves to be at moderate-to-high HIV risk, 23.6% were unaware of PrEP, 40.1% were not

    Ultrasound elastography reveals the elastic property of biological tissues. It quantifies the characteristics felt by palpation to some extent, and thus has an extensive value in scientific studies and clinical practices. After reviewing its background and study progress, this paper provides a preliminary analysis and discussion of the problems encountered in clinical practice. Further studies are expected to help doctors better assess the elastogram of tissues for objective diagnosis.%静态超声弹性成像(Ultrasound Elastography)利用超声探测技术,检查组织的弹性特征,从一定程度上量化反映了医生在触诊中的主观感受,在科学研究和临床实践中有广泛的应用价值.本文综述了该项技术的研究背景、研究进展,并对其临床中遇到的问题做了初步的分析和探讨.以期通过今后的研究,帮助医生更好地获得弹性图像(Elastogram),继而做出客观诊断.

    Full Text Available Abstract Background The use of compulsory treatment under the Mental Health Act (MHA has continued to rise in the UK and in other countries. The Joint Crisis Plan (JCP is a statement of service users' wishes for treatment in the event of a future mental health crisis. It is developed with the clinical team and an independent facilitator. A recent pilot RCT showed a reduction in the use of the MHA amongst service users with a JCP. The JCP is the only intervention that has been shown to reduce compulsory treatment in this way. The CRIMSON trial aims to determine if JCPs, compared with treatment as usual, are effective in reducing the use of the MHA in a range of treatment settings across the UK. Methods/Design This is a 3 centre, individual-level, single-blind, randomised controlled trial of the JCP compared with treatment as usual for people with a history of relapsing psychotic illness in Birmingham, London and Lancashire/Manchester. 540 service users will be recruited across the three sites. Eligible service users will be adults with a diagnosis of a psychotic disorder (including bipolar disorder, treated in the community under the Care Programme Approach with at least one admission to a psychiatric inpatient ward in the previous two years. Current inpatients and those subject to a community treatment order will be excluded to avoid any potential perceived pressure to participate. Research assessments will be conducted at baseline and 18 months. Following the baseline assessment, eligible service users will be randomly allocated to either develop a Joint Crisis Plan or continue with treatment as usual. Outcome will be assessed at 18 months with assessors blind to treatment allocation. The primary outcome is the proportion of service users treated or otherwise detained under an order of the Mental Health Act (MHA during the follow-up period, compared across randomisation groups. Secondary outcomes include overall costs, service user engagement

    With the content analysis method, this paper uses statistic evidence and analysis of the discourses in Harvard Educational Review (HER) from 1931 to 2000 to discuss the transformation of educational research, which has turned from "teaching object" to "teaching subject". What is more, education research is not only aimed at pursuing the efficiency of teaching, but also showing more concern for the individuals in the process of teaching.
