    The present study tested the effect of conscientiousness and neuroticism on health and physical limitations in a representative sample of older couples (N= 2,203) drawn from the Health and Retirement Study. As in past research, conscientiousness predicted better health and physical functioning, whereas neuroticism predicted worse health and physical functioning. Unique to this study was the finding that conscientiousness demonstrated a compensatory effect, such that husbands' conscientiousness predicted wives' health outcomes above and beyond wives' own personality. The same pattern held true for wives' conscientiousness as a predictor of husbands' health outcomes. Furthermore, conscientiousness and neuroticism acted synergistically, such that people who scored high for both traits were healthier than others. Finally, we found that the combination of high conscientiousness and high neuroticism was also compensatory, such that the wives of men with this combination of personality traits reported better health than other women.

    Previous findings have demonstrated that chronotype (morningness/intermediate/eveningness) is correlated with cognitive functions, that is, people show higher mental performance when they do a test at their preferred time of day. Empirical studies found a relationship between morningness and higher learning achievement at school and university. However, only a few of them controlled for other moderating and mediating variables. In this study, we included chronotype, gender, conscientiousness and test anxiety in a structural equation model (SEM) with grade point average (GPA) as academic achievement outcome. Participants were 158 high school students and results revealed that boys and girls differed in GPA and test anxiety significantly, with girls reporting better grades and higher test anxiety. Moreover, there was a positive correlation between conscientiousness and GPA (r = 0.17) and morningness (r = 0.29), respectively, and a negative correlation between conscientiousness and test anxiety (r = -0.22). The SEM demonstrated that gender was the strongest predictor of academic achievement. Lower test anxiety predicted higher GPA in girls but not in boys. Additionally, chronotype as moderator revealed a significant association between gender and GPA for evening types and intermediate types, while intermediate types showed a significant relationship between test anxiety and GPA. Our results suggest that gender is an essential predictor of academic achievement even stronger than low or absent test anxiety. Future studies are needed to explore how gender and chronotype act together in a longitudinal panel design and how chronotype is mediated by conscientiousness in the prediction of academic achievement.

    This article assesses whether perceived parental style influenced the extent to which adolescents became increasingly conscientious and whether changes in conscientiousness influenced academic grades 1 year later. Parental styles, conscientiousness, verbal, and numerical ability at Time 1 were measured. One year later conscientiousness was again assessed, and 1 year after that end-of-year exam results were obtained. More than 784 students (mean age=12.3 years, SD=0.49) participated in the 1st year. The data of 563 students were matched across the 3 years. Conscientiousness tended to decrease from Time 1 to Time 2. Structural equation modeling showed that adolescents with more authoritative parents experienced less of a decrease in conscientiousness at Time 2 than did students with less authoritative parents and the same baseline level of conscientiousness at Time 1. Additionally, the decrease in conscientiousness at Time 2 predicted worse grades at Time 3, even after controlling for baseline levels of academic achievement.

    The current study examined the relationship between conscientiousness, work status, and volunteering utilizing two large samples, the St. Louis Personality and Aging Network (SPAN) and the Health and Retirement Study (HRS). It was hypothesized that conscientious adults who were retired would be more likely to volunteer because, after retirement, they gain a substantial amount of free time, while losing an outlet for their industrious and achievement-striving tendencies. Cross-sectional and longitudinal analyses revealed that conscientious, retired individuals were more likely to volunteer than conscientious, working individuals. Further analyses revealed that facets of conscientiousness provide differential information from the general trait. These findings indicate that volunteering during retirement fills an important niche for high-striving, conscientious individuals.

  6. Conscientious Objection to Vaccination.

    Vaccine refusal occurs for a variety of reasons. In this article we examine vaccine refusals that are made on conscientious grounds; that is, for religious, moral, or philosophical reasons. We focus on two questions: first, whether people should be entitled to conscientiously object to vaccination against contagious diseases (either for themselves or for their children); second, if so, to what constraints or requirements should conscientious objection (CO) to vaccination be subject. To address these questions, we consider an analogy between CO to vaccination and CO to military service. We argue that conscientious objectors to vaccination should make an appropriate contribution to society in lieu of being vaccinated. The contribution to be made will depend on the severity of the relevant disease(s), its morbidity, and also the likelihood that vaccine refusal will lead to harm. In particular, the contribution required will depend on whether the rate of CO in a given population threatens herd immunity to the disease in question: for severe or highly contagious diseases, if the population rate of CO becomes high enough to threaten herd immunity, the requirements for CO could become so onerous that CO, though in principle permissible, would be de facto impermissible.

    Greater levels of conscientiousness have been associated with lower levels of negative affect. We focus on one mechanism through which conscientiousness may decrease negative affect: effective emotion regulation, as reflected by greater recovery from negative stimuli. In 273 adults who were 35-85 years old, we collected self-report measures of personality including conscientiousness and its self-control facet, followed on average 2 years later by psychophysiological measures of emotional reactivity and recovery. Among middle-aged adults (35-65 years old), the measures of conscientiousness and self-control predicted greater recovery from, but not reactivity to, negative emotional stimuli. The effect of conscientiousness and self-control on recovery was not driven by other personality variables or by greater task adherence on the part of high conscientiousness individuals. In addition, the effect was specific to negative emotional stimuli and did not hold for neutral or positive emotional stimuli.

    Existing research on Big Five personality and unemployment has relied on personality measures elicited after the respondents had already spent years in the labor market, an experience that could change personality. We clarify the direction of influence by using the British Cohort Study (N = 4,206) to examine whether conscientiousness and other Big Five personality traits at age 16-17 predict unemployment over age 16-42. Our hypothesis that higher conscientiousness in adolescence would predict lower unemployment was supported. In analyses controlling for intelligence, gender, and parental socioeconomic status, the less conscientious (-1 SD) had a predicted probability of unemployment twice as high (3.4% vs. 1.7%) as the highly conscientious (+1 SD), an effect size comparable to intelligence. Mediation analysis revealed that academic motivation and educational attainment explained only 8.9% of this association. Fostering conscientiousness in early life may be an effective way to reduce unemployment throughout adulthood. (PsycINFO Database Record

  11. Do students learn to be more conscientious at medical school?

    Full Text Available Abstract Background Professionalism in medical students is not only difficult to define but difficult to teach and measure. As negative behaviour in medical students is associated with post-graduate disciplinary action it would be useful to have a model whereby unprofessional behaviour at the undergraduate level can easily be identified to permit appropriate intervention. We have previously developed a scalar measure of conscientiousness, the Conscientiousness Index (CI, which positively correlates to estimates of professional behaviour in undergraduate medical students. By comparing CI points awarded in year 1 and year 2 of study we were able to use the CI model to determine whether teaching and clinical exposure had any effect on students’ conscientiousness. Methods CI points were collected by administrative staff from 3 successive cohorts of students in years 1 and 2 of study. Points were awarded to students for activities such as submission of immunisation status and criminal record checks, submission of summative assignments by a specified date and attendance at compulsory teaching sessions. CI points were then converted to a percentage of maximal possible scores (CI % to permit direct comparison between years 1 and 2 of study. Results CI % scores were generally high with each year of study for each cohort showing negatively skewed normal distributions with peaks > 89%. There was a high degree of correlation of CI % scores between year 1 and year 2 of study for each cohort alone and when cohort data was combined. When the change in CI % from year 1 to year 2 for all students was compared there was no significant difference in conscientiousness observed. Conclusions We have provided evidence that use of a CI model in undergraduate medical students provides a reliable measure of conscientiousness that is easy to implement. Importantly this study shows that measurement of conscientiousness by the CI model in medical students does not change

It appears to be regarded as fundamentally different from other kinds of objection. But why? This study argues that conscientious obje

    The error-related negativity (ERN) is a neural measure of error processing that has been implicated as a neurobehavioral trait and has transdiagnostic links with psychopathology. Few studies, however, have contextualized this traitlike component with regard to dimensions of personality that, as intermediate constructs, may aid in contextualizing links with psychopathology. Accordingly, the aim of this study was to examine the interrelationships between error monitoring and dimensions of personality within a large adult sample (N = 208). Building on previous research, we found that the ERN relates to a combination of negative affect, impulsivity, and conscientiousness. At low levels of conscientiousness, negative urgency (i.e., impulsivity in the context of negative affect) predicted an increased ERN; at high levels of conscientiousness, the effect of negative urgency was not significant. This relationship was driven specifically by the conscientiousness facets of competence, order, and deliberation. Links between personality measures and error positivity amplitude were weaker and nonsignificant. Post-error slowing was also related to conscientiousness, as well as a different facet of impulsivity: lack of perseverance. These findings suggest that, in the general population, error processing is modulated by the joint combination of negative affect, impulsivity, and conscientiousness (i.e., the profile across traits), perhaps more so than any one dimension alone. This work may inform future research concerning aberrant error processing in clinical populations.

    Conscientious objection refers to the possibility that an individual decides not to comply with a legal mandate because of his or hers convictions, which is accepted by some political constitutions. The classical example is to refuse participation in obligatory military service for personal reasons of conscience, but in the present paper we refer to its use in medical practice utilizing three examples: euthanasia, abortion and the refusal to prescribe emergency contraception. We conclude that in all situations patients rights supersedes conscientious objection.

    The law regulating abortion in Italy gives healthcare practitioners the option to make a conscientious objection to activities that are specific and necessary to an abortive intervention. Conscientious objectors among Italian gynaecologists amount to about 70%. This means that only a few doctors are available to perform abortions, and therefore access to abortion is subject to constraints. In 2012 the International Planned Parenthood Federation European Network (IPPF EN) lodged a complaint against Italy to the European Committee of Social Rights, claiming that the inadequate protection of the right to access abortion implies a violation of the right to health. In this paper I will discuss the Italian situation with respect to conscientious objection to abortion and I will suggest possible solutions to the problem.

  1. The Conscientious Responders Scale

    2014-07-01

    Full Text Available This investigation introduces a novel tool for identifying conscientious responders (CRs and random responders (RRs in psychological inventory data. The Conscientious Responders Scale (CRS is a five-item validity measure that uses instructional items to identify responders. Because each item instructs responders exactly how to answer that particular item, each response can be scored as either correct or incorrect. Given the long odds of answering a CRS item correctly by chance alone on a 7-point scale (14.29%, we reasoned that RRs would answer most items incorrectly, whereas CRs would answer them correctly. This rationale was evaluated in two experiments in which CRs’ CRS scores were compared against RRs’ scores. As predicted, results showed large differences in CRS scores across responder groups. Moreover, the CRS correctly classified responders as either conscientious or random with greater than 93% accuracy. Implications for the reliability and effectiveness of the CRS are discussed.

  2. Hostile climate, abusive supervision, and employee coping: does conscientiousness matter?

    2014-07-01

    The current study draws on the transactional theory of stress to propose that employees cope with hostile work environments by engaging in emotion-based coping in the forms of organization-directed deviance and psychological withdrawal. Specifically, we propose that supervisors' hostile organizational climate perceptions act as distal environmental stressors that are partially transmitted through supervisors' abusive actions and that conscientiousness moderates the proposed effects. First, we hypothesize that supervisor conscientiousness has a buffering effect by decreasing the likelihood of abusive supervision. Second, we hypothesize that highly conscientious employees cope differently from less conscientious employees. Among a sample of employees and their immediate supervisors, results indicated that while hostile climate perceptions provide a breeding ground for destructive behaviors, conscientious individuals are less likely to respond to perceived hostility with hostile acts. As supervisor conscientious levels increased, supervisors were less likely to engage in abusive supervision, which buffered employees from the negative effects of hostile climate perceptions. However, when working for less conscientious supervisors, employees experienced the effects of perceived hostile climates indirectly through abusive supervision. In turn, less conscientious employees tended to cope with the stress of hostile environments transmitted through abusive supervision by engaging in acts of organization-directed deviance. At the same time, all employees, regardless of their levels of conscientiousness, tended to cope with their hostile environments by psychologically withdrawing. Theoretical and practical implications are discussed.

  3. Conscientiousness increases efficiency of multicomponent behavior.

    Many everyday situations require the flexible interruption and changing of different actions to achieve a goal. Several strategies can be applied to do so, but those requiring high levels of cognitive control seem to confer an efficiency (speed) advantage in situations requiring multi-component behavior. However, it is elusive in how far personality traits affect performance in such situations. Given that top-down control is an important aspect of personality and furthermore correlates with conscientiousness, N = 163 participants completed the NEO-FFI and performed an experimental (stop-change) paradigm assessing multicomponent behavior. Applying mathematical constraints to the behavioral data, we estimated the processing strategy of each individual. The results show that multicomponent behavior is selectively affected by conscientiousness which explained approximately 19% of the measured inter-individual behavioral variance. Conscientiousness should hence be seen as a major personality dimension modulating multicomponent behavior. Highly conscientious people showed a more effective, step-by-step processing strategy of different actions necessary to achieve a goal. In situations with simultaneous requirements, this strategy equipped them with an efficiency (speed) advantage towards individuals with lower conscientiousness. In sum, the results show that strategies and the efficiency with which people cope with situations requiring multicomponent behavior are strongly influenced by their personality.

    2011-07-01

    A dimensional perspective on personality disorder hypothesizes that the current diagnostic categories represent maladaptive variants of general personality traits. However, a fundamental foundation of this viewpoint is that dimensional models can adequately account for the pathology currently described by these categories. While most of the personality disorders have well established links to dimensional models that buttress this hypothesis, obsessive-compulsive personality disorder (OCPD) has obtained only inconsistent support. The current study administered multiple measures of 1) conscientiousness-related personality traits, 2) DSM-IV OCPD, and 3) specific components of OCPD (e.g., compulsivity and perfectionism) to a sample of 536 undergraduates who were oversampled for elevated OCPD scores. Six existing measures of conscientiousness-related personality traits converged strongly with each other supporting their assessment of a common trait. These measures of conscientiousness correlated highly with scales assessing specific components of OCPD, but obtained variable relationships with measures of DSM-IV OCPD. More specifically, there were differences within the conscientiousness instruments such that those designed to assess general personality functioning had small to medium relationships with OCPD, but those assessing more maladaptive variants obtained large effect sizes. These findings support the view that OCPD does represent a maladaptive variant of normal-range conscientiousness.

    2007-01-01

    Conscientious objection to democratically accepted laws in democratic societies is a fact, both among citizens and among professionals. Due respect for laws is a prima facie duty in these societies. But democratic justice must at the same time respect peoples' conscience for it constitutes the ethical identity of individuals. And both law and ethics are necessary - although neither of them is sufficient - for its realization. The problem of conscientious objection among healthcare professionals is analysed from this standpoint and the conclusion is that objection is not an absolute right to exemption from several duties, but that the responsibility of the professional and of the institutions towards the citizenry must always be taken into account. Some solutions are suggested that try to protect both the professionals and the citizens in a bi-directional way.

The nature of conscientious objection will be investigated and an ethical analysis of conscientious objection will be conducted. Finally some suggestions for health care policy will be proposed.

    2016-09-12

    Conscientious objection to abortion - a clinician's refusal to perform abortions because of moral or religious beliefs - is a limited right, intended to protect clinicians' convictions while maintaining abortion access. This paper argues that conscientious objection policies and debates around the world generally do not take into account the social, political, and economic pressures that profoundly influence clinicians who must decide whether to claim objector status. Lack of clarity about abortion policies, high workload, low pay, and stigma towards abortion providers can discourage abortion provision. As the only legal way to refuse to provide abortions that are permitted by law, conscientious objection can become a safety valve for clinicians under pressure and may be claimed by clinicians who do not have moral or religious objections. Social factors including stigma also shape how stakeholders and policy-makers approach conscientious objection. To appropriately limit the scope of conscientious objection and make protection of conscience more meaningful, more information is needed about how conscientious objection is practised. Additionally, abortion trainings should include information about conscientious objection and its limits, reproductive rights, and creating an enabling environment for abortion provision. Policy-makers and all stakeholders should also focus on creating an enabling environment and reducing stigma.

    2002-02-01

    The authors hypothesized that the relationship between conscientiousness and job performance would be stronger for persons high in agreeableness than for those low in agreeableness. Results of hierarchical moderated regression analyses for 7 independent samples of employees across diverse occupations provided support for the hypothesis in 5 of the samples. In samples supporting the hypothesis, among the highly conscientious workers, those low in agreeableness were found to receive lower ratings of job performance than workers high in agreeableness. One explanation for lack of an interaction between conscientiousness and agreeableness in the other 2 samples is that those jobs were not characterized by frequent, cooperative interactions with others. Overall, the results show that highly conscientious workers who lack interpersonal sensitivity may be ineffective, particularly in jobs requiring cooperative interchange with others.

  10. Individual Differences in Loss Aversion: Conscientiousness Predicts How Life Satisfaction Responds to Losses Versus Gains in Income.

    Boyce, Christopher J; Wood, Alex M; Ferguson, Eamonn

    2016-04-01

    Loss aversion is considered a general pervasive bias occurring regardless of the context or the person making the decision. We hypothesized that conscientiousness would predict an aversion to losses in the financial domain. We index loss aversion by the relative impact of income losses and gains on life satisfaction. In a representative German sample (N = 105,558; replicated in a British sample, N = 33,848), with conscientiousness measured at baseline, those high on conscientiousness have the strongest reactions to income losses, suggesting a pronounced loss aversion effect, whereas for those moderately unconscientious, there is no loss aversion effect. Our research (a) provides the first evidence of personality moderation of any loss aversion phenomena, (b) supports contextual perspectives that both personality and situational factors need to be examined in combination, (c) shows that the small but robust relationship between income and life satisfaction is driven primarily by a subset of people experiencing highly impactful losses.

  11. Conscientious commitment to women's health.

    2011-05-01

    Conscientious commitment, the reverse of conscientious objection, inspires healthcare providers to overcome barriers to delivery of reproductive services to protect and advance women's health. History shows social reformers experiencing religious condemnation and imprisonment for promoting means of birth control, until access became popularly accepted. Voluntary sterilization generally followed this pattern to acceptance, but overcoming resistance to voluntary abortion calls for courage and remains challenging. The challenge is aggravated by religious doctrines that view treatment of ectopic pregnancy, spontaneous abortion, and emergency contraception not by reference to women's healthcare needs, but through the lens of abortion. However, modern legal systems increasingly reject this myopic approach. Providers' conscientious commitment is to deliver treatments directed to women's healthcare needs, giving priority to patient care over adherence to conservative religious doctrines or religious self-interest. The development of in vitro fertilization to address childlessness further illustrates the inspiration of conscientious commitment over conservative objections.

    Polish laws specify the parties responsible for lawful medical care in the availability of abortion differently than the Resolution of the Council of Europe. According to Polish regulations they include all Polish doctors while according to the Resolution, the state. Polish rules should not discriminate against anyone in connection with his religion or belief, even more so because the issue of abortion is an example of an unresolved ethical dispute. The number of lawful abortion in Poland does not exceed 1000 per year and can be carried out by only a few specialists contracted by the National Health Fund. Sufficient information and assistance should be provided to all pregnant women by the National Health Fund. The participation of all physicians in the informing process is not necessary, as evidenced by the lack of complaints to provide information on where in vitro fertilization treatment can be found - until recently only available when paid for by the individual and performed in much larger numbers than abortion. Entities performing this paid procedure made sure to provide information on their own. The rejection of the right to the conscientious objection clause by negating the right to refuse information may lead some to give up the profession or cause the termination of certain professionals on the basis of the professed worldview. Meanwhile, doctors are not allowed to be discriminated against on the basis of their conscience or religion.

    Although reasonably strong support has been obtained for the Five-Factor Model's (FFM) ability to account for the existing personality disorder (PD) constructs, the support for obsessive-compulsive PD (OCPD) and dependent PD (DPD) has been relatively less consistent. Specifically, the expected correlation between OCPD and the FFM trait of Conscientiousness has varied in magnitude across studies while DPD has, at times, also evinced rather weak relationships with FFM Agreeableness. We determined that these inconsistencies were due primarily to the reliance on FFM measures that lack adequate fidelity to assess the maladaptive aspects of high Conscientiousness and Agreeableness. When alternative measures were utilized, the correlations were generally large and in line with expectations. We conclude that OCPD and DPD can be fruitfully conceptualized within the FFM but encourage the use of measures that provide a comprehensive assessment of both the adaptive and maladaptive aspects of the FFM traits.

Over the past several months, conscientious refusal disputes have had an unusually high profile not only in courthouses, but also in legislative and regulatory halls across the United States. Healthcare providers' own moral beliefs have been obstructing and are expected to increasingly obstruct patients' access to medical services. For example, some providers, on ethical or moral grounds, have denied: (1) sterilization procedures to pregnant patients, (2) pain medications in end-of-life situations, and (3) information about emergency contraception to rape victims. On the other hand, many healthcare providers have been forced to provide medical treatment that is inconsistent with their moral beliefs. There are two fundamental types of conscientious objection laws. First, there are laws that permit healthcare workers to refuse providing - on ethical, moral, or religious grounds healthcare services that they might otherwise have a legal or employer-mandated obligation to provide. Second, there are laws directed at forcing healthcare workers to provide services to which they might have ethical, moral, or religious objections. Both types of laws are rarely comprehensive, but instead target: (1) certain types of healthcare providers, (2) specific categories of healthcare services, (3) specific patient circumstances, and (4) certain conditions under which a right or obligation is triggered. For the sake of clarity, I have grouped recent legal developments concerning conscientious refusal into eight categories: 1. Abortion: right to refuse 2. Abortion: duty to provide 3. Contraception: right to refuse 4. Contraception: duty to provide 5. Sterilization: right to refuse 6. Fertility, HIV, vaccines

    The authors discuss the emergency contraception (EC) topic, assessing scientific and ethical aspects. The almost totality of the studies carried out tends to report on the use of drugs as an emergency measure to prevent pregnancy. However, it is not yet completely excluded that emergency contraceptives can induce medical abortion. The debate on side effects of EC continues to be a highly emotional and controversial issue both for advocates who believe they will lower considerably the number of unintended pregnancies and abortions, and for opponents who believe that using emergency contraception amounts to an abortion. This latter hypothesis highlights the conflicting aspect of the conscientious objection to abortion of physicians and pharmacists. This research work is aimed at investigating the emergency contraception issue, paying particular attention to the medico-legal and regulatory aspects of this subject. Particularly, the authors focus on the conscientious objection in order to assess, if any, legal protection for physicians and pharmacists who claim a right to conscientious objection. Inappropriate use of EC could be resolved through a registry of user. This registry, of course, would not have the intention of persecution, but would only serve to detect possible cases of subjugation, exploitation and harassment.

  16. rganizational features as situational strength: engaging the low-conscientious employee

    Full Text Available One of the most robust findings in work psychology is the role that conscientiousness plays in performance; more recently, research indicates that conscientious employees are also the most engaged in their work. The present study examines whether the organization has any role in this relation, and if it is possible for individuals who are low in conscientiousness to also feel high levels of engagement. One hundred forty-one full-time Romanian workers and their peers, representing a variety of industries, were surveyed, revealing that features of the organization can actually attenuate the relation between conscientiousness and engagement. Specifically, when employees perceive that the organization is relatively formalized (i.e., where following rules is important, and in organizations where there is a perception that effort is rewarded, conscientiousness is not as strongly associated with engagement. These organizational features represent situational strength, and when situations are strong, scripts and rules tend to predict behavior, rather than personality. As such, it may be possible for low-conscientiousness individuals to actually become more engaged through organizational change. For those who are low in conscientiousness, for example, a formal work environment likely provides structure and decreases ambiguity, which aids in lower conscientious employees becoming more engaged. Similarly, when it is perceived that the organization rewards effort, those who are low in conscientiousness receive this reinforcement, and likely benefit the most, as their levels of engagement tend to approach those who are higher in conscientiousness.

  17. Resonant High Power Combiners

    Particle accelerators need radio frequency sources. Above 300 MHz, the amplifiers mostly used high power klystrons developed for this sole purpose. As for military equipment, users are drawn to buy "off the shelf" components rather than dedicated devices. IOTs have replaced most klystrons in TV transmitters and find their way in particle accelerators. They are less bulky, easier to replace, more efficient at reduced power. They are also far less powerful. What is the benefit of very compact sources if huge 3 dB couplers are needed to combine the power? To alleviate this drawback, we investigated a resonant combiner, operating in TM010 mode, able to combine 3 to 5 IOTs. Our IOTs being able to deliver 80 kW C.W. apiece, combined power would reach 400 kW minus the minor insertion loss. Values for matching and insertion loss are given. The behavior of the system in case of IOT failure is analyzed.

  18. The Chernyshenko Conscientiousness Scales: A New Facet Measure of Conscientiousness.

    2016-06-01

    The current research sought to validate the Chernyshenko Conscientiousness Scales (CCS), a novel measure designed to assess six facets of conscientiousness. Data from 7,569 U.S. participants and 649 U.K. participants were analyzed to assess the internal reliability and factorial structure of the scales. Test-retest reliability, convergent and divergent validity, and criterion-related validity were also evaluated using a separate U.K. sample (n = 118; n = 80 for test-retest). The results showed that those items designed to measure industriousness, order, self-control, traditionalism, and virtue were best represented by a five-factor structure, broadly consistent with the five scales. However, the content and structure of the responsibility scale requires further investigation. Overall, the CCS has the potential to be a useful alternative to the faceted measures of conscientiousness that are currently available. However, future research is required to refine a number of problematic items and to clarify which facets can be better described as interstitial dimensions between conscientiousness and other Big Five domains.

    Conscientiousness is associated with health, but the mechanisms remain poorly understood. To explore the role that stress might play, this study examined whether conscientiousness was associated with exposure and reactivity to life stress. This study followed 133 adolescent women every 6 months for 2.5 years. Participants completed a baseline measure of conscientiousness, and at each visit underwent a structured interview to catalogue episodic and chronic stress and had blood drawn to assess inflammatory processes. Participants higher in conscientiousness experienced fewer self-dependent episodic stressors and less academic and interpersonal chronic stress throughout the study. However, at times when they experienced higher levels of chronic interpersonal stress, they became more resistant to glucocorticoids. Higher levels of conscientiousness may protect adolescent women from exposure to certain stressors. However, when stress occurs, highly conscientious individuals may become more resistant to glucocorticoids, increasing their risk for processes that influence inflammatory conditions.

  1. Conscientiousness and agreeableness as predictors of rating leniency.

    Bernardin, H J; Cooke, D K; Villanova, P

    2000-04-01

    The authors studied the relationship between the Big Five personality factors and rating elevation among 111 students making peer evaluations. It was hypothesized that Conscientiousness (C) scores would be negatively correlated with rating level and that Agreeableness (A) scores would be positively correlated with rating level. We further predicted that individuals who were low on C and high on A would produce the most elevated ratings. As predicted, A scores were positively related to rating level (.33, p < .01) and C scores were negatively correlated with rating level (-.37, p < .01). Using the strong hypothesis test (P. Bobko, 1986), the authors found that ratings by low C and high A individuals were more elevated than all other groups of students combined (p < .01).

    Although conscientiousness has for a long time been considered generally adaptive, there are findings challenging this view, suggesting that conscientiousness might be less advantageous during uncontrollable stress. We here examined the impact of conscientiousness on brain activation during and the cortisol response following an uncontrollable social evaluative stress task in order to test this hypothesis. Brain activation and cortisol levels were measured during an fMRI stress task, where subjects (n=86) performed cognitive tasks containing preprogrammed failure under time pressure, while being monitored by a panel of experts inducing social-evaluative threat. The degree of conscientiousness was measured using the NEO-FFI. We observed a positive correlation between conscientiousness and salivary cortisol levels in response to the stressful task in male subjects only. In male subjects conscientiousness correlated positively with activation in right amygdala and left insula, and, moreover, mediated the influence of amygdala and insula activation on cortisol output. This pattern of brain activation can be interpreted as a disadvantageous response to uncontrollable stress to which highly conscientious individuals might be predisposed. This is the first study showing the effect of conscientiousness on physiology and brain activation to an uncontrollable psychosocial stressor. Our results provide neurobiological evidence for the hypothesis that conscientiousness should not just be seen as beneficial, but rather as a trait associated with either costs or benefits depending on the extent to which one is in control of the situation.

  3. [Conscientious objection in medical practice].

    Science.gov (United States)

    Beca, Juan Pablo I; Astete, Carmen A

    2015-04-01

    Medical practice implies the controversial encounter of diverse circumstances in which eventual conflicts between physicians and patients values as well as between physicians values and legal or institutional rules arise. When dealing with these situations, physicians have the right to refuse acting against their moral conscience. This conscientious objection, accepted as a personal right and recognized by several legislations and medical ethics codes, is valid only if it has been reasonably justified and declared in advance. Conversely, it would be invalid if it is based upon convenience or understood as a collective refusal, which may be a form of civil disobedience. Conscientious objection in medicine is considered a limited right even though patients ought to be respected in their demands for legally accepted treatments or interventions. On the other hand, personal conscientious objection is different from the prerogative of institutions to establish their own regulations according to their institutional ideology or ethics codes. However, public hospitals have to offer all treatments or interventions legally allowed, since the state has the obligation to guarantee all citizens an appropriate access to them.

  5. Neuroticism and Conscientiousness as Moderators of the Relation Between Social Withdrawal and Internalizing Problems in Adolescence.

    Smith, Kelly A; Barstead, Matthew G; Rubin, Kenneth H

    2017-04-01

    Social withdrawal, or refraining from social interaction in the presence of peers, places adolescents at risk of developing emotional problems like anxiety and depression. The personality traits of neuroticism and conscientiousness also relate to emotional difficulties. For example, high conscientiousness predicts lower incidence of anxiety disorders and depression, while high neuroticism relates to greater likelihood of these problems. Based on these associations, socially withdrawn adolescents high in conscientiousness or low in neuroticism were expected to have lower levels of anxiety and depressive symptoms. Participants included 103 adolescents (59 % female) who reported on their personality traits in 8th grade and their anxiety and depressive symptoms in 9th grade. Peer ratings of social withdrawal were collected within schools in 8th grade. A structural equation model revealed that 8th grade withdrawal positively predicted 9th grade anxiety and depressive symptoms controlling for 8th grade anxiety and depressive symptoms, but neuroticism did not. Conscientiousness moderated the relation of withdrawal with depressive symptoms but not anxiety, such that high levels of conscientiousness attenuated the association between withdrawal and depressive symptoms. This buffering effect may stem from the conceptual relation between conscientiousness and self-regulation. Conscientiousness did not, however, moderate the association between withdrawal and anxiety, which may be partly due to the role anxiety plays in driving withdrawal. Thus, a conscientious, well-regulated personality partially protects withdrawn adolescents from the increased risk of emotional difficulties.

    Conscientiousness and domain-specific competence beliefs are known to be highly important predictors of academic effort and achievement. Given their basis in distinct research traditions, however, these constructs have rarely been examined simultaneously. Three studies with 571, 415, and 1,535 students, respectively, found a moderate association between conscientiousness and competence beliefs. Both conscientiousness and competence beliefs meaningfully predicted academic effort, irrespective of how academic effort was measured (single-measurement questionnaire or diary data). The associations of competence beliefs with academic effort were highly domain specific, whereas conscientiousness was predictive of academic effort across a wide range of academic subjects. Conscientiousness and competence beliefs were also associated with academic achievement. Figural and verbal reasoning ability, although associated with academic achievement, only loosely predicted academic effort.

    The present study aims to explore the relationship between conscientiousness and the consumption of healthy versus unhealthy main meals. Impulsive eating was tested as a mediator in this relationship, as well as direct effects of age on those constructs. A nationwide representative sample of 1,006 Norwegian adults (18-70 years) within a prospective design was used to test a theoretical model. The structural equation model (SEM), in combination with bootstrapping procedures in AMOS, was the principal analytical method. Conscientiousness was negatively associated with unhealthy and impulsive eating. Impulsive eating was a partial mediator between conscientiousness and unhealthy eating and a full mediator between conscientiousness and healthy eating. Age was positively correlated with conscientiousness and this relationship had an inverted U-shape form. Finally, age was negatively associated with unhealthy and impulsive eating, and positively associated with healthy eating. This study confirmed the relevance of conscientiousness for healthy, unhealthy, and impulsive eating.

    In this paper, I analyse the issue of conscientious objection in relation to cosmetic surgery. I consider cases of doctors who might refuse to perform a cosmetic treatment because: (1) the treatment aims at achieving a goal which is not in the traditional scope of cosmetic surgery; (2) the motivation of the patient to undergo the surgery is considered trivial; (3) the patient wants to use the surgery to promote moral or political values that conflict with the doctor's ones; (4) the patient requires an intervention that would benefit himself/herself, but could damage society at large.

    The purpose of this experiment was to examine the interplay of goal content, conscientiousness, and tension on performance following negative feedback. Undergraduate students were assigned either a learning or performance goal and then were provided with false feedback indicating very poor performance on the task they performed. After assessing tension, participants performed the task again with the same learning or performance goal. A mediated moderation model was tested, and results were supportive of our hypotheses. Specifically, individuals assigned a learning goal experienced less tension and performed better following negative feedback than individuals assigned a performance goal. Individuals high in conscientiousness experienced greater tension than individuals low in conscientiousness. Conscientiousness and goal content interacted in relating to both tension and performance, with tension as a mediator, such that high conscientiousness amplified the detrimental effect of a performance goal on tension following negative feedback leading to lower performance. High conscientiousness facilitated performance for participants with a learning goal.

    2010-09-01

    In this paper we argue that nurse leaders need to work actively to create morally supportive environments for nurses in Canada that provide adequate room to exercise conscientious objection. Morally supportive environments engender a safe atmosphere to engage in open dialogue and action regarding conflict of conscience. The CNA's 2008 Code of Ethics for Registered Nurses has recognized the importance of conscientious objection in nursing and has created key guidelines for the registered nurse to follow when a conflict in conscience is being considered or declared. Nurse leaders need to further develop the understanding of conflicts of conscience through education, well-written guidelines for conscientious objection in workplaces and engagement in research to uncover underlying barriers to the enactment of conscientious objections. With advancements in technology, changing healthcare policies and increasing scope of practice, both reflection and dialogue on conscientious objection are critical for the continuing moral development of nurses in Canada.

  14. When should conscientious objection be accepted?

    Science.gov (United States)

    Magelssen, Morten

    2012-01-01

    This paper makes two main claims: first, that the need to protect health professionals' moral integrity is what grounds the right to conscientious objection in health care; and second, that for a given claim of conscientious objection to be acceptable to society, a certain set of criteria should be fulfilled. The importance of moral integrity for individuals and society, including its special role in health care, is advocated. Criteria for evaluating the acceptability of claims to conscientious objection are outlined. The precise content of the criteria is dictated by the two main interests that are at stake in the dilemma of conscientious objection: the patient's interests and the health professional's moral integrity. Alternative criteria proposed by other authors are challenged. The bold claim is made that conscientious objection should be recognised by society as acceptable whenever the five main criteria of the proposed set are met.

    Grit and the Big Five Inventory (BFI) Conscientiousness dimension were examined with respect to the transtheoretical model (TTM) stages of change for exercise behavior. Participants (N = 1171) completed an online survey containing exercise-related TTM staging questions, the Short Grit Scale and BFI Conscientiousness. Ordinal regression analyses showed that grit significantly predicted high intensity and moderate intensity exercise TTM stage while BFI Conscientiousness did not. The results suggest that grit is a potentially important differentiator of TTM stage for moderate and high intensity exercise.

    The present study examines a mediated moderation model of the effects of conscientiousness and coping strategies on the relationship between abusive supervision and employees' job performance. Across 2 studies conducted in India, we found evidence that the relationship between abusive supervision and job performance was weaker when employees were high in conscientiousness. In addition, we found that the use of an avoidance coping strategy facilitated a negative relationship between abusive supervision and performance. Finally, we found that the moderating effects of conscientiousness were mediated by the use of avoidance coping strategies. Our findings contribute to theories of abusive supervision, personality, coping strategies, and job performance.

    2017-01-01

    This article analyzes the idea of a legal right to conscientious refusal for healthcare professionals from a basic legal ethical standpoint, using refusal to perform tasks related to legal abortion (in cases of voluntary employment) as a case in point. The idea of a legal right to conscientious refusal is distinguished from ideas regarding moral rights or reasons related to conscientious refusal, and none of the latter are found to support the notion of a legal right. Reasons for allowing some sort of room for conscientious refusal for healthcare professionals based on the importance of cultural identity and the fostering of a critical atmosphere might provide some support, if no countervailing factors apply. One such factor is that a legal right to healthcare professionals' conscientious refusal must comply with basic legal ethical tenets regarding the rule of law and equal treatment, and this requirement is found to create serious problems for those wishing to defend the idea under consideration. We conclude that the notion of a legal right to conscientious refusal for any profession is either fundamentally incompatible with elementary legal ethical requirements, or implausible because it undermines the functioning of a related professional sector (healthcare) or even of society as a whole.

    We investigated the effect of verbal encouragement on maximal voluntary contraction (MVC) level of the triceps surae muscle group. Our secondary focus was to examine whether the effect of verbal encouragement on MVC level varies as a result of conscientiousness. While the participants performed plantar flexion, MVCs of the triceps surae muscle group were measured using rectified and smoothed surface electromyography (rsEMG) during the absence and presence of verbal encouragement. Participants completed questions from the Five Factor Personality Inventory concerning conscientiousness and were divided into high- and low-conscientiousness groups according to a median split. The sample included 30 female and 53 male elite athletes. In the entire cohort, there was no significant difference in MVCs with and without verbal encouragement. When the sample was partitioned by conscientiousness scores, verbal encouragement led to a significant increase in MVC in the low-conscientiousness group, whereas verbal encouragement led to a non-significant decrease in MVC in the high-conscientiousness group. Percentage change in MVC across experimental conditions was significantly different between the groups, with a 9.72% increase during verbal encouragement of the low-conscientiousness group, and a 2.47% decrease during verbal encouragement of the high-conscientiousness group.

    2012-08-01

    Although the research literature has established that Conscientiousness predicts task performance across a variety of achievement contexts (e.g., ; ), comparatively less is known about the processes that underlie these relations. To the latter end, the current research examines effortful strategies and achievement goals as mediating factors that might explain why people with higher levels of Conscientiousness are predicted to reach higher levels of academic performance. In a longitudinal study, 347 college students completed measures of personality and achievement goals at the beginning of the class, followed by measures of effortful strategies multiple times throughout the semester. Results support the hypothesis that effortful strategies mediate the association between Conscientiousness and academic performance. Moreover, the statistical effects of Conscientiousness were generally independent of achievement goals, but a small portion of the effect was mediated through approach, not avoidance, achievement goals. These results highlight the importance of examining mediating processes between personality and outcomes, and in the case of Conscientiousness, our results suggest that effortful strategies might serve as a useful target for performance-enhancing interventions.

  2. General job performance of first-line supervisors: the role of conscientiousness in determining its effects on subordinate exhaustion.

    Perry, Sara Jansen; Rubino, Cristina; Witt, L A

    2011-04-01

    In an integrated test of the job demands-resources model and trait activation theory, we predicted that the general job performance of employees who also hold supervisory roles may act as a demand to subordinates, depending on levels of subordinate conscientiousness. In a sample of 313 customer service call centre employees, we found that high-conscientiousness individuals were more likely to experience emotional exhaustion, and low-conscientiousness individuals were less likely as the general job performance of their supervisor improved. The results were curvilinear, such that high-conscientiousness individuals' exhaustion levelled off with very high supervisor performance (two standard deviations above the mean), and low-conscientiousness individuals' exhaustion levelled off as supervisor performance improved from moderate to high. These findings suggest high-conscientiousness employees may efficiently handle demands presented by a low-performing coworker who is their boss, but when performance expectations are high (i.e. high-performing boss), these achievement-oriented employees may direct their resources (i.e. energy and time) towards performance-related efforts at the expense of their well-being. Conversely, low-conscientiousness employees suffer when paired with a low-performing boss, but benefit from a supervisor who demonstrates at least moderate job performance.

    2014-07-01

    Some philosophers have argued for what I call the reason-giving requirement for conscientious refusal in reproductive healthcare. According to this requirement, healthcare practitioners who conscientiously object to administering standard forms of treatment must have arguments to back up their conscience, arguments that are purely public in character. I argue that such a requirement, though attractive in some ways, faces an overlooked epistemic problem: it is either too easy or too difficult to satisfy in standard cases. I close by briefly considering whether a version of the reason-giving requirement can be salvaged despite this important difficulty.

  9. Conscientious Non-objection in Intensive Care.

    Wilkinson, Dominic

    2017-01-01

    Discussions of conscientious objection (CO) in healthcare often concentrate on objections to interventions that relate to reproduction, such as termination of pregnancy or contraception. Nevertheless, questions of conscience can arise in other areas of medicine. For example, the intensive care unit is a locus of ethically complex and contested decisions. Ethical debate about CO usually concentrates on the issue of whether physicians should be permitted to object to particular courses of treatment; whether CO should be accommodated. In this article, I focus on the question of how clinicians ought to act: should they provide or support a course of action that is contrary to their deeply held moral beliefs? I discuss two secular examples of potential CO in intensive care, and propose that clinicians should adopt a norm of conscientious non-objection (CNO). In the face of divergent values and practice, physicians should set aside their personal moral beliefs and not object to treatment that is legally and professionally accepted and provided by their peers. Although there may be reason to permit conscientious objections in healthcare, conscientious non-objection should be encouraged, taught, and supported.

    2013-01-01

    Full Text Available Orientation: The study investigates factors that impact work-family conflict and work engagement among working mothers.Research purpose: The job demand-resources model is utilised to investigate the moderating role of conscientiousness and neuroticism on the relationship between work-family conflict and work engagement.Motivation for the study: Working mothers are challenged to establish a balance between work and family life. The resulting work-family conflict can negatively affect well-being. It is thus necessary to explore personal factors that relate to work-family conflict, particularly in the South African context.Research design, approach and method: A quantitative, cross-sectional survey design was used. The sample (N = 267 was comprised of working mothers from several organisations. Data was gathered using the work-to-family conflict questionnaire, the Basic Traits Inventory and the Utrecht Work Engagement Scale.Main findings: The results indicated that work-family conflict negatively predicts work engagement. Conscientiousness positively predicts work engagement, and neuroticism negatively predicts work engagement. A significant interaction effect was found for conscientiousness but not for neuroticism. The findings showed that for participants with high levels of conscientiousness, work engagement decreases significantly more with an increase in work-family conflict than for participants with low levels of conscientiousness.Practical/Managerial implications: Organisations should consider those individuals who have high levels of conscientiousness and low levels of neuroticism in the selection and placement of employees. In addition, organisations have a responsibility to provide conscientious women, particularly mothers, with adequate support to ensure that work-family conflict does not adversely impact their levels of work engagement.

  13. Childhood Conscientiousness and Leukocyte Telomere Length 40 Years Later in Adult Women--Preliminary Findings of a Prospective Association.

    Full Text Available Leukocyte telomere length (LTL shortens with age, and is a prospective marker of mortality related to cardiovascular disease. Many health behaviors and social environmental factors have been found to be associated with LTL. Several of these are also associated with conscientiousness, a dispositional personality trait. Conscientiousness is a propensity to be planful, adhere to social norms, and inhibit pre-potent responses. Like LTL, conscientiousness is prospectively related to mortality, possibly through cumulative effects on health over the life course via multiple pathways. As a result, we hypothesized that childhood levels of conscientiousness would predict LTL prospectively in adulthood. We selected a sample of 60 women in the Hawaii Personality and Health Cohort; 30 described by their teachers as high on conscientiousness in childhood and 30 described as low on the trait. Dried blood spot samples collected in adulthood 40 years later were used as sources of DNA for the LTL assay. Conscientiousness was associated with longer LTL (p = .02. Controlling for age did not account for this association. Controlling for education and physiological dysregulation partially attenuated the association, and the effect remained significant when accounting for differences in LTL across cultural groups. These results represent the first evidence that childhood personality prospectively predicts LTL 40 years later in adulthood. Our findings would be consistent with a mediation hypothesis whereby conscientiousness predicts life paths and trajectories of health that are reflected in rates of LTL erosion across the lifespan.

  15. Conscientious refusal to assist with abortion.

    Science.gov (United States)

    Dooley, D

    1994-09-10

    Abortion is a moral issue affecting the identity and integrity of physicians and nurses. Ethical reasoning helps reasonable and sincere people who do not agree on abortion to understand the sources of disagreement and to explore shared principles in the differences. Discussions of abortion cannot be limited to the conflict between the rights of a woman to control her reproduction and the rights of a fetus to live. Religious, cultural, feminist, and political beliefs must also be considered. This complexity must be considered when examining whether physicians and nurses have rights to refuse to assist in abortion on conscientious grounds. People with fundamentally different moral outlooks already determine what is morally right or wrong, good or evil. Health professionals who refuse to assist in abortion base their decision on beliefs about moral duties, injunctions of natural law, and the essentially nonnegotiable rights of people to be protected from intentional harm. They know and regret the adverse effects for pregnant women but there is no compelling motivation to change their opposition to abortion. There is no morally neutral position from which to judge conscientious refusals in abortion. Society should develop a position that respects autonomy of belief and grants the right to physicians and nurses to conscientiously refuse to assist in abortions. In those countries where the abortion law grants physicians the right to refuse but not nurses, society needs to reflect on why nurses have been accorded second class professional and moral status. In those countries which have not yet formulated an abortion law, the government should consider how it can find enough health workers who will in good conscience assist in abortions. Governments must first seriously consider a presumptive right to conscientious refusal in abortion before health systems can redistribute sectors of responsibility among health workers and implement changes in recruitment policies for

  16. Conscientious Objection in Healthcare and Moral Integrity.

    2017-01-01

    There are several reasons for accommodating health professionals' conscientious objections. However, several authors have argued that among the most important and compelling reasons is to enable health professionals to maintain their moral integrity. Accommodation is said to provide "moral space" in which health professionals can practice without compromising their moral integrity. There are, however, alternative conceptions of moral integrity and corresponding different criteria for moral-integrity-based claims. It is argued that one conception of moral integrity, the identity conception, is sound and suitable in the specific context of responding to health professionals' conscientious objections and their requests for accommodation. According to the identity conception, one maintains one's moral integrity if and only if one's actions are consistent with one's core moral convictions. The identity conception has been subject to a number of criticisms that might call into question its suitability as a standard for determining whether health professionals have genuine moral-integrity-based accommodation claims. The following five objections to the identity conception are critically examined: (1) it does not include a social component, (2) it is a conception of subjective rather than objective integrity, (3) it does not include a reasonableness condition, (4) it does not include any substantive moral constraints, and (5) it does not include any intellectual integrity requirement. In response to these objections, it is argued that none establishes the unsuitability of the identity conception in the specific context of responding to health professionals' conscientious objections and their requests for accommodation.

  17. Conscientious refusal in healthcare: the Swedish solution.

    Science.gov (United States)

    Munthe, Christian

    2017-04-01

    The Swedish solution to the legal handling of professional conscientious refusal in healthcare is described. No legal right to conscientious refusal for any profession or class of professional tasks exists in Sweden, regardless of the religious or moral background of the objection. The background of this can be found in strong convictions about the importance of public service provision and related civic duties, and ideals about rule of law, equality and non-discrimination. Employee's requests to change work tasks are handled on a case-by-case basis within the frames of labour law, ensuring full voluntariness, and also employer's privilege regarding the organisation and direction of work, and duties of public institutions to provide services. Two complicating aspects of this solution related to the inclusion of 'alternative medical' service providers in a national health service, and professional insistence on conscientious refusal rights to accept legalised assisted dying are discussed. The latter is found to undermine the pragmatic reasons behind recent attempts by prolife groups to challenge the Swedish solution related to legal abortion in courts.

    2010-03-01

    The personality trait of conscientiousness is an important predictor of health and longevity. The present research examined how conscientiousness, in combination with educational attainment and health-related behaviours, predicted self-reported physical health across adulthood. These relations were investigated in two studies, one using a large, representative sample of Illinois residents (N = 617) and the other using a community sample with a multi-method assessment of conscientiousness (N = 274). Across both studies, structural path analyses provided evidence for a model wherein conscientiousness predicted health, in part, through its relationship to both educational attainment and health-related behaviours. The findings suggest conscientiousness predicts health through a diverse set of mechanisms including, but not limited to, educational attainment and health-related behaviours.

    We investigated the effect of positive and negative feedback on maximal voluntary contraction (MVC) of the biceps brachii muscle and explored the mediating effects of gender and conscientiousness. During elbow flexion, MVCs were measured in positive, negative, and no-feedback conditions. Participants were divided into high- and low-conscientiousness groups based on the median split of their scores on Tatar's five-factor personality inventory. Considering all participants 46 college student athletes (21 female, 28 male), positive feedback led to a greater MVC percentage change (-5.76%) than did negative feedback (2.2%). MVC percentage change in the positive feedback condition differed significantly by gender, but the negative feedback condition did not. Thus, positive feedback increased female athletes' MVC level by 3.49%, but decreased male athletes' MVC level by 15.6%. For conscientiousness, MVC percentage change in the positive feedback condition did not differ according to high and low conscientiousness. However, conscientiousness interacted with gender in the positive feedback condition, increasing MVC in high-conscientiousness female athletes and decreasing MVC in low-conscientiousness female athletes. Positive feedback decreased MVC in both high- and low-conscientiousness male athletes.

    The current study examined how specific neurological systems contribute to the expression of multiple personality dimensions. We used individuals with traumatic brain injuries to examine the contribution of the dorsolateral prefrontal cortex (DLPFC)--a region important for executive function and attention-to the expression of neuroticism and conscientiousness factors and facets. Results from Voxel-Based Lesion-Symptom Mapping analyses revealed that focal damage to the left DLPFC (Brodmann's area 9) was associated with high neuroticism and low conscientious factor and facet scores (anxiety and self-discipline, respectively). Compared with lesioned and normal controls, veterans with damage in left DLPFC also reported higher neuroticism and lower conscientiousness facet scores, slower reaction times on the California Computerized Assessment Package assessment, and lower scores on the Delis-Kaplan executive function battery. Findings suggest that while neuroticism and conscientiousness remain psychometrically independent personality dimensions, their component facets may rely on a common neurocognitive infrastructure and executive function resources in general.

  1. Conscientious objections in pharmacy practice in Great Britain.

    Deans, Zuzana

    2013-01-01

    Pharmacists who refuse to provide certain services or treatment for reasons of conscience have been criticized for failing to fulfil their professional obligations. Currently, individual pharmacists in Great Britain can withhold services or treatment for moral or religious reasons, provided they refer the patient to an alternative source. The most high-profile cases have concerned the refusal to supply emergency hormonal contraception, which will serve as an example in this article. I propose that the pharmacy profession's policy on conscientious objections should be altered slightly. Building on the work of Brock and Wicclair, I argue that conscientious refusals should be acceptable provided that the patient is informed of the service, the patient is redirected to an alternative source, the refusal does not cause an unreasonable burden to the patient, and the reasons for the refusal are based on the core values of the profession. Finally, I argue that a principled categorical refusal by an individual pharmacist is not morally permissible. I claim that, contrary to current practice, a pharmacist cannot legitimately claim universal exemption from providing a standard service, even if that service is available elsewhere.

  3. Legal protection and limits of conscientious objection: when conscientious objection is unethical.

    Science.gov (United States)

    Dickens, Bernard M

    2009-03-01

    The right to conscientious objection is founded on human rights to act according to individuals' religious and other conscience. Domestic and international human rights laws recognize such entitlements. Healthcare providers cannot be discriminated against, for instance in employment, on the basis of their beliefs. They are required, however, to be equally respectful of rights to conscience of patients and potential patients. They cannot invoke their human rights to violate the human rights of others. There are legal limits to conscientious objection. Laws in some jurisdictions unethically abuse religious conscience by granting excessive rights to refuse care.. In general, healthcare providers owe duties of care to patients that may conflict with their refusal of care on grounds of conscience. The reconciliation of patients' rights to care and providers' rights of conscientious objection is in the duty of objectors in good faith to refer their patients to reasonably accessible providers who are known not to object. Conscientious objection is unethical when healthcare practitioners treat patients only as means to their own spiritual ends. Practitioners who would place their own spiritual or other interests above their patients' healthcare interests have a conflict of interest, which is unethical if not appropriately declared.

    Ability to self-regulate varies and self-regulatory strength is a limited source that can be depleted or fatigued. Research on the impact of individual differences on self-regulatory capacity is still scarce, and this study aimed to examine whether personality factors such as dispositional optimism, conscientiousness, and self-consciousness can impact or buffer self-regulatory fatigue. Participants were patients diagnosed with chronic multi-symptom illnesses (N = 50), or pain free matched controls (N = 50), randomly assigned to either a high or low self-regulation task, followed by a persistence task. Higher optimism predicted longer persistence (p = .04), and there was a trend towards the same effect for conscientiousness (p = .08). The optimism by self-regulation interaction was significant (p = .01), but rather than persisting despite self-regulatory effort, optimists persisted longer only when not experiencing self-regulatory fatigue. The effects of optimism were stronger for controls than patients. There was also a trend towards a similar conscientiousness by self-regulation interaction (p = .06). These results suggest that the well-established positive impact of optimism and conscientiousness on engagement and persistence may be diminished or reversed in the presence of self-regulatory effort or fatigue, adding an important new chapter to the self-regulation, personality, and pain literature.

    Science.gov (United States)

    Wicclair, Mark R

    2014-09-01

    It is argued that the primary aim of institutional management is to protect the moral integrity of health professionals without significantly compromising other important values and interests. Institutional policies are recommended as a means to promote fair, consistent, and transparent management of conscience-based refusals. It is further recommended that those policies include the following four requirements: (1) Conscience-based refusals will be accommodated only if a requested accommodation will not impede a patient's/surrogate's timely access to information, counseling, and referral. (2) Conscience-based refusals will be accommodated only if a requested accommodation will not impede a patient's timely access to health care services offered within the institution. (3) Conscience-based refusals will be accommodated only if the accommodation will not impose excessive burdens on colleagues, supervisors, department heads, other administrators, or the institution. (4) Whenever feasible, health professionals should provide advance notification to department heads or supervisors. Formal review may not be required in all cases, but when it is appropriate, several recommendations are offered about standards and the review process. A key recommendation is that when reviewing an objector's reasons, contrary to what some have proposed, it is not appropriate to adopt an adversarial approach modelled on military review boards' assessments of requests for conscientious objector status. According to the approach recommended, the primary function of reviews of objectors' reasons is to engage them in a process of reflecting on the nature and depth of their objections, with the objective of facilitating moral clarity on the part of objectors rather than enabling department heads, supervisors, or ethics committees to determine whether conscientious objections are sufficiently genuine.

  11. Specificity matters: criterion-related validity of contextualized and facet measures of conscientiousness in predicting college student performance.

    Woo, Sang Eun; Jin, Jing; LeBreton, James M

    2015-01-01

    To enhance the predictive validity of self-report personality measures, 2 distinct ways of increasing specificity of personality measures have been proposed in the literature-contextual specificity (i.e., providing a contextual referent) and content specificity (i.e., focusing on more specific constructs such as the Big Five facets). This study extends this line of research by examining whether there is an optimal way to configure, align, or integrate contextual and content specificity using measures of conscientiousness to predict college student success. A sample of 478 undergraduate students completed 4 measures of conscientiousness that varied in the level of content and contextual specificity. These forms of specificity were crossed to yield 4 distinct measures of conscientiousness. We then evaluated and compared the relative importance and the incremental importance of these different measures in the prediction of academic success. Superior predictive validity was found for both contextualized and facet measures of conscientiousness compared to a measure of global conscientiousness in predicting grade-point average and a broader behavioral criterion of student performance. When contextual and content specificity approaches were compared and combined, we observed the strongest predictive validity when the level of specificity is appropriately matched between predictor and criterion.

  12. Conscientious objection in healthcare, referral and the military analogy.

    Science.gov (United States)

    Clarke, Steve

    2017-04-01

    An analogy is sometimes drawn between the proper treatment of conscientious objectors in healthcare and in military contexts. In this paper, I consider an aspect of this analogy that has not, to my knowledge, been considered in debates about conscientious objection in healthcare. In the USA and elsewhere, tribunals have been tasked with the responsibility of recommending particular forms of alternative service for conscientious objectors. Military conscripts who have a conscientious objection to active military service, and whose objections are deemed acceptable, are required either to serve the military in a non-combat role, or assigned some form of community service that does not contribute to the effectiveness of the military. I argue that consideration of the role that military tribunals have played in determining the appropriate form of alternative service for conscripts who are conscientious objectors can help us to understand how conscientious objectors in healthcare ought to be treated. Additionally, I show that it helps us to address the vexed issue of whether or not conscientious objectors who refuse to provide a service requested by a patient should be required to refer that patient to another healthcare professional.

    2017-01-01

    The etiology of late onset Alzheimer's disease (LOAD) depends on multiple factors, among which the APOE ɛ4 allele is the most adverse genetic determinant and conscientiousness represents an influential personality trait. A potential association of both factors with brain structure in young adulthood may constitute a constellation that sets the course toward or against the subtle disease progression of LOAD that starts decades before clinical manifestation. Hence, in the present study, we examined the modulating effects of APOE ɛ4 on the relation between personality dimensions, including conscientiousness, and total grey matter volume (GMV) in young healthy adults using an a priori genotyping design. 105 participants completed an inventory assessing the Five Factor Model of Personality (NEO-FFI) and a structural MRI scan. Total GMV was estimated using both Freesurfer as well as VBM8. Across all participants, total GMV was positively associated with extraversion and negatively related to age. In APOE ɛ4-carriers- but not in APOE ɛ4-non-carriers- conscientiousness was negatively associated with total GMV. In line with the hypothesis of antagonistic pleiotropy of the APOE ɛ4 allele, this result suggests that young APOE ɛ4-carriers with increased total GMV may particularly benefit from cognitive advantages and thus have a lower need to engage in conscientious behavior. In this subset of young APOE ɛ4-carriers, the reduction in conscientiousness could then bring along adverse health behavior in the long run, potentiating the risk for LOAD. Hence, young APOE ɛ4-carriers with increased total GMV may be at a particularly high risk for LOAD.

    2012-02-01

    We conducted 3 studies to test the idea that guilt is a key affective component of Conscientiousness and that it can account for the relation between Conscientiousness and negative affect. Study 1 used meta-analysis to show that Conscientiousness was associated with specific emotions and overall negative affect but was most strongly associated with guilt. Conscientiousness was negatively related to guilt experience but positively related to guilt proneness. Also, guilt experience mediated the relation between Conscientiousness and negative affect. Study 2 (N = 142) examined the relation between facets of Conscientiousness and guilt. We replicated results from Study 1 and showed that the relation between Conscientiousness and guilt was not due to overlap with Extraversion and Neuroticism. Study 3 (n = 176) examined the interplay between Conscientiousness and guilt on grades in a short-term longitudinal study. These studies showed that Conscientiousness is primarily related to guilt and highlighted the importance of examining the emotional substrate of Conscientiousness.

Since exact knowledge of this severe, although rare syndrome is important for any perioperative or intensive medical treatment concerning therapy and progression of the disease, we report a comprehensive study on a 32-year old woman with this rare multifaceted disorder who had to undergo general anaesthesia. For the first time amino acid status in plasma, urine, cerebrospinal fluid and especially polymorphonuclear leucocytes, which in the investigation showed to be valuable tool for evaluating amino acid metabolism in nucleated cells in HHH-syndrome, and further important pathophysiologic indicators of cellular and metabolic function have been conscientiously investigated and compared. The pathophysiological repercussions of our results as well as the recommendations for conscientious therapeutical management are discussed.

  17. Conscientious objection in healthcare: why tribunals might be the answer.

    2017-04-01

    A recent focus of the debate on conscientious objection in healthcare is the question of whether practitioners should have to justify their refusal to perform certain functions. A recent article by Cowley addresses a practical aspect of this controversy, namely the question of whether doctors claiming conscientious objector status in relation to abortion should be required, like their counterparts claiming exemption from military conscription, to defend their claim before a tribunal. Cowley argues against the use of tribunals in the medical case, on the grounds that there are likely to be fewer unjustified claims to conscientious objection in this context than in the military, and that in any case tribunals will not be an effective way of distinguishing genuine and false cases. I reject these arguments and propose a different conception of the role of a medical conscientious objection tribunal.

  18. Personality-intelligence interface : the relationship between conscientiousness and intelligence

    The aim of this study was to investigate the relationship between conscientiousness and intelligence. Specifically, this study intended to replicate a previous study by Moutafi et. al. (2004) that found conscientiousness to be negatively correlated with intelligence (Moutafi, Furnham, & Paltiel, 2004). It was proposed that this negative relationship could be explained by the theory of compensation, which hypothesized that individuals low on fluid intelligence could compensate for ...

  19. The work-family interface and job performance: moderating effects of conscientiousness and perceived organizational support.

    Based on conservation of resources (COR) theory, the authors hypothesized that two aspects of the work-family interface--family-to-work conflict (FWC) and family-to-work enrichment (FWE)--are related to job performance. The authors also hypothesized that two variables moderate those relationships--individual differences in conscientiousness and aspects of the work environment in terms of perceived organizational support (POS). Data collected from a matched set of 136 private sector workers and their respective supervisors revealed that high FWC was more strongly related to lower job performance: (1) among high- than low-conscientiousness workers and (2) among workers reporting low rather than high levels of organizational support. However, FWE was unrelated to job performance.

    The issue of conscientious objection (CO) arises in healthcare when doctors and nurses refuse to have any involvement in the provision of treatment of certain patients due to their religious or moral beliefs. Most commonly CO is invoked when it comes to induced abortion. Of the EU member states where induced abortion is legal, invoking CO is granted by law in 21 countries. The same applies to the non-EU countries Norway and Switzerland. CO is not legally granted in the EU member states Sweden, Finland, Bulgaria and the Czech Republic. The Icelandic legislation provides no right to CO either. European examples prove that the recommendation that CO should not prevent women from accessing services fails in a number of cases. CO puts women in an unequal position depending on their place of residence, socio-economic status and income. CO should not be presented as a question that relates only to health professionals and their rights. CO mainly concerns women as it has very real consequences for their reproductive health and rights. European countries should assess the laws governing CO and its effects on women's rights. CO should not be used as a subtle method for limiting the legal right to healthcare.

  1. Conscientiousness, dementia related pathology, and trajectories of cognitive aging.

    The study aim was to determine the contribution of dementia related pathologies to the association of conscientiousness with late-life cognitive health. At enrollment in 2 longitudinal clinical-pathologic cohort studies, 309 older individuals without cognitive impairment completed a standard conscientiousness measure. Annually thereafter, they completed a battery of 17 cognitive tests. On death, they underwent a uniform neuropathologic examination from which measures of neurofibrillary tangles, Lewy bodies, chronic gross cerebral infarction, and hippocampal sclerosis were derived. The relation of conscientiousness and the neuropathologic markers to cognitive decline was assessed in mixed-effects change point models to accommodate nonlinear cognitive decline. During a mean of 10.7 years of follow-up, annual decline on a composite measure of global cognition (baseline M = 0.082, SD = 0.499) was gradual (estimated M = -0.036, 95% CI [-0.046, -0.025]) until a mean of 3.2 years before death (95% CI [-3.6, -2.8]) when it accelerated to a mean annual loss of 0.369 unit (95% CI [-0.426, -0.317]), a tenfold increase. Higher conscientiousness (baseline M = 33.6, SD = 5.1) was associated with slower terminal decline (estimate = 0.064, 95% CI [0.024, 0.103]) but not preterminal decline (estimate = 0.005, 95% CI [-0.003, 0.013]). After adjustment for neuropathologic burden, conscientiousness was still related to terminal decline (estimate = 0.057, 95% CI [0.019, 0.094]) and accounted for 4% of the variance in terminal slopes. In addition, the association of neocortical Lewy bodies with terminal cognitive decline was attenuated in those with higher conscientiousness. The results suggest that higher conscientiousness is protective of late-life cognitive health.

  2. Conscientious objection and reproductive health service delivery in sub-Saharan Africa.

    Lema, V M

    2012-03-01

    Lack of access to quality reproductive health services is the main contributor to the high maternal mortality and morbidity in sub-Saharan Africa (SSA). This is partly due to a shortage of qualified and experienced health care providers. However conscientious objection amongst the available few is a hitherto undocumented potential factor influencing access to health care in SSA. Provision of certain reproductive health services goes counter to some individual's religious and moral beliefs and practices. Health providers sometimes refuse to participate in or provide such services to clients/patients on moral and/or religious grounds. While the rights to do so are protected by the principles of freedom of religion, among other documents, their refusal exposes clients/patients to the risk of reproductive health morbidity as well as mortality. Such providers are required to refer the clients/patients to other equally qualified and experienced providers who do not hold similar conscientious objection. Access to high quality and evidence-based reproductive health services by all in need is critical to attaining MDG5. In addressing factors contributing to delay in attaining MDG5 in SSA it is instructive to consider the role of conscientious objection in influencing access to quality reproductive health care services and strategies to address it.

  3. The impact of conscientiousness, mastery, and work circumstances on subsequent absenteeism in employees with and without affective disorders.

    High numbers of employees are coping with affective disorders. At the same time, ambitiousness, achievement striving and a strong sense of personal control and responsibility are personality characteristics that are nowadays regarded as key to good work functioning, whereas social work circumstances tend to be neglected. However, it is largely unkown how personality characteristics and work circumstances affect work functioning when facing an affective disorder. Given the high burden of affective disorders on occupational health, we investigate these issues in the context of affective disorders and absenteeism from work. The principal aim of this paper is to examine whether particular personality characteristics that reflect self-governance (conscientiousness and mastery) and work circumstances (demands, control, support) influence the impact of affective disorders on long-term absenteeism (>10 working days). Baseline and 1-year follow-up data from 1249 participants in the Netherlands Study of Depression and Anxiety (NESDA) in 2004-2006 was employed. Multivariate logistic regression analyses were performed, including interaction effects between depressive, anxiety, and comorbid disorders and personality and work circumstances. In general, mastery and conscientiousness increased nor diminished odds of subsequent long-term absenteeism, whereas higher job support significantly decreased these odds. Interaction effects showed that the impact of affective disorders on absenteeism was stronger for highly conscientious employees and for employees who experienced high job demands. Affective disorders may particularly severely affect work functioning of employees who are highly conscientious or face high psychological job demands. Adjusting working conditions to their individual needs may prevent excessive work absence.

    2009-01-01

    The present paper focuses on the trait domain of conscientiousness, its development, and its relation to psychopathology. The definition of conscientiousness and its interface with specific forms of psychopathology, such as externalizing psychopathology, are discussed first. Then an overview of the known developmental changes in conscientiousness across the life course is provided, as well as the potential shared developmental etiology of conscientiousness and externalizing psychopathology. Given the lack of data, testing etiological factors that may contribute to the development of both conscientiousness and externalizing disorders, we report on three studies examining the childhood experiences associated with both conscientiousness and externalizing behaviors. Last, future directions are discussed.

  5. Toward accommodating physicians' conscientious objections: an argument for public disclosure.

    Harter, Thomas D

    2015-03-01

    This paper aims to demonstrate how public disclosure can be used to balance physicians' conscientious objections with their professional obligations to patients--specifically respect for patient autonomy and informed consent. It is argued here that physicians should be permitted to exercise conscientious objections, but that they have a professional obligation to provide advance notification to patients about those objections. It is further argued here that public disclosure is an appropriate and ethically justifiable limit to the principle of advance notification. The argument for publicly disclosing physicians' conscientious objections is made in this paper by discussing three practical benefits of public disclosure in medicine, and then addressing how publicly disclosing physicians' conscientious objections is not an undue invasion of privacy. Three additional concerns with public disclosure of physicians' conscientious objections are briefly addressed--potential harassment of physicians, workplace discrimination, and mischaracterising physicians' professional aptitude--concluding that each of these concerns requires further deliberation in the realm of business ethics.

  6. Self-compassion and relationship maintenance: the moderating roles of conscientiousness and gender.

    2011-05-01

    Should intimates respond to their interpersonal mistakes with self-criticism or with self-compassion? Although it is reasonable to expect self-compassion to benefit relationships by promoting self-esteem, it is also reasonable to expect self-compassion to hurt relationships by removing intimates' motivation to correct their interpersonal mistakes. Two correlational studies, 1 experiment, and 1 longitudinal study demonstrated that whether self-compassion helps or hurts relationships depends on the presence versus absence of dispositional sources of the motivation to correct interpersonal mistakes. Among men, the implications of self-compassion were moderated by conscientiousness. Among men high in conscientiousness, self-compassion was associated with greater motivation to correct interpersonal mistakes (Studies 1 and 3), observations of more constructive problem-solving behaviors (Study 2), reports of more accommodation (Study 3), and fewer declines in marital satisfaction that were mediated by decreases in interpersonal problem severity (Study 4); among men low in conscientiousness, self-compassion was associated with these outcomes in the opposite direction. Among women, in contrast, likely because women are inherently more motivated than men to preserve their relationships for cultural and/or biological reasons, self-compassion was never harmful to the relationship. Instead, women's self-compassion was positively associated with the motivation to correct their interpersonal mistakes (Study 1) and changes in relationship satisfaction (Study 4), regardless of conscientiousness. Accordingly, theoretical descriptions of the implications of self-promoting thoughts for relationships may be most complete to the extent that they consider the presence versus absence of other sources of the motivation to correct interpersonal mistakes.

    2009-11-01

    Integrating the theory of planned behaviour (TPB) with the five-factor model (FFM) of personality may provide insight into the cognitive and motivational mechanisms linking personality with health behaviour, but this issue has received very little attention regarding fruit consumption. Mediator effects of TPB concepts in the personality-fruit consumption link, as well as moderator effects of personality in the intention-fruit consumption link, were therefore investigated in the present study. Data on fruit consumption, TPB concepts and FFM dimensions were gathered among 405 respondents in face-to-face interviews using questionnaires. Structural equation modelling was used to investigate the mediator and moderator effects. The direct effect of conscientiousness on fruit consumption was mediated by attitude and perceived behavioural control, while no direct effect of neuroticism on fruit consumption was found. Neuroticism moderated the intention-fruit consumption relationship with the weakest relationship for those scoring high on neuroticism. Conscientiousness did not moderate the intention-fruit consumption relationship. TPB variables are mediators in the conscientiousness-fruit consumption link. Whether fruit consumption is intentional may be dependent upon the personality dimension neuroticism. Personality dimensions may be a useful addition to the TPB and should be considered in health behaviour change interventions.

  8. Participation in Organized Activities Protects Against Adolescents' Risky Substance Use, Even Beyond Development in Conscientiousness.

    Adolescents are at a significant risk for binge drinking and illicit drug use. One way to protect against these behaviors is through participation in extracurricular activities. However, there is a debate about whether highly conscientious adolescents are more likely to participate in activities, which raises the concern of a confound. To disentangle these relationships, we tested the latent trajectories of substance use and personality across 3 years, with participation in activities and sports as time-varying predictors. We surveyed 687 adolescents (55 % female, 85.4 % Caucasian) in Western Australia schools across 3 years. At Time 1, the students were in Year 10 1 (mean age 15 years). The results showed that participation in activities and conscientiousness are related, but each uniquely predicts slower growth in substance use. Across waves, participation in activities predicted less risky substance use a year later, over and above conscientiousness development. These results suggest that there may be unique benefits of participation in activities that protect against risky substance use.

    We conducted 3 studies to test the idea that guilt is a key affective component of Conscientiousness and that it can account for the relation between Conscientiousness and negative affect. Study 1 used meta-analysis to show that Conscientiousness was associated with specific emotions and overall negative affect but was most strongly associated with guilt. Conscientiousness was negatively related to guilt experience but positively related to guilt proneness. Also, guilt experience mediated the...

    The main objective of this paper is to highlight the numerous conflicts enters the consciousness and the laws are becoming more frequent health professionals in daily clinical practice. Clarify and define concepts such as ″conscientious objection for health professionals, to avoid confusion with other terms. This is work that aims to address the objection of conscience, not from the law but from the ethics and deontology, reviewing existing regulations both internationally and nationally. In addition to complete the studio, in a last part we discuss the state of the ″conscientious objection″ tars the recent passage of the organic law 2 / 2010, 3 march, sexual and reproductive health and the interruption of pregnancy. As a final conclusion we can say that ″conscientious objection″ is recognized in international declarations and even in the european constitution. in spain, the code of ethics and medical ethics, is one of the places where the objection of conscience of health professionals has great development for years, states that the doctor can refrain from the practice of certain professional acts such as abortion, in vitro fertilization or sterilization, if they are in contradiction with its ethical and scientific beliefs. Also recently, the general assembly of october 24, 2009, the central committee of ethics has made a declaration on ″conscientious objection″, insisting on its recognition. Finally, the organic law 2 / 2010, 3 march, sexual and reproductive health and the interruption of pregnancy, seems to be recognized ″the right to exercise conscientious objection″ of health professionals directly involved in the voluntary termination of pregnancy, after much discussion, but it is still early to assess the implementation of this right because, until july 5, 2010, will come into force this law, what will the future that we clarify the development of this important right for health professionals.

    Local and landscape-scale agricultural intensification is a major driver of global biodiversity loss. Controversially discussed solutions include wildlife-friendly farming or combining high-intensity farming with land-sparing for nature. Here, we integrate biodiversity and crop productivity data for smallholder cacao in Indonesia to exemplify for tropical agroforests that there is little relationship between yield and biodiversity under current management, opening substantial opportunities for wildlife-friendly management. Species richness of trees, fungi, invertebrates, and vertebrates did not decrease with yield. Moderate shade, adequate labor, and input level can be combined with a complex habitat structure to provide high biodiversity as well as high yields. Although livelihood impacts are held up as a major obstacle for wildlife-friendly farming in the tropics, our results suggest that in some situations, agroforests can be designed to optimize both biodiversity and crop production benefits without adding pressure to convert natural habitat to farmland.

    This article is an exploratory effort meant to solicit and provoke dialog. Conscientious objection is proposed as a potential response to the moral distress experienced by neonatal nurses. The most commonly reported cause of distress for all nurses is following orders to support patients at the end of their lives with advanced technology when palliative or comfort care would be more humane. Nurses report that they feel they are harming patients or causing suffering when they could be comforting instead. We examined the literature on moral distress, futility, and the concept of conscientious objection from the perspective of the nurse's potential response to performing advanced technologic interventions for the dying patient. We created a small pilot study to engage in clinical verification of the use of our concept of conscientious objection. Data from 66 neonatal intensive care and pediatric intensive care unit nurses who responded in a one-month period are reported here. Interest in conscientious objection to care that causes harm or suffering was very high. This article reports the analysis of conscientious objection use in neonatal care.

    2013-12-01

    Despite advances in scientific evidence, technologies, and human rights rationale for providing safe abortion, a broad range of cultural, regulatory, and health system barriers that deter access to abortion continues to exist in many countries. When conscientious objection to provision of abortion becomes one of these barriers, it can create risks to women's health and the enjoyment of their human rights. To eliminate this barrier, states should implement regulations for healthcare providers on how to invoke conscientious objection without jeopardizing women's access to safe, legal abortion services, especially with regard to timely referral for care and in emergency cases when referral is not possible. In addition, states should take all necessary measures to ensure that all women and adolescents have the means to prevent unintended pregnancies and to obtain safe abortion.

    2017-04-01

    This paper builds upon previous work in which I argue that we should assess a provider's reasons for his or her objection before granting a conscientious exemption. For instance, if the medical professional's reasoned basis involves an empirical mistake, an accommodation is not warranted. This article poses and begins to address several deep questions about the workings of what I call a reason-giving view: What standard should we use to assess reasons? What policy should we adopt in order to evaluate the reasons offered by medical practitioners in support of their objections? I argue for a reasonability standard to perform the essential function of assessing reasons, and I offer considerations in support of a policy establishing conscientious objector status in medicine.

    Conscience can influence physicians' interactions with patients in myriad ways and, by extension, can influence the interactions and internal dynamics of a health care team. The AMA's opinion around physicians' exercise of conscience appropriately balance the obligations physicians have to their patients and profession, and the rights of physicians as moral agents to exercise their conscience. While the opinion is an effective starting point, further guidance is necessary to clarify the process by which physicians should identify, manage, and, if necessary, report their conscientious refusals to patients, supervisors, or colleagues. In addition to laying out a proposed process for identifying and managing issues of conscience, this article will use relevant and timely examples to help clarify how a physician could apply this process in an instance of conscientious refusal.

    Previous research has shown broad relationships between personality and dance, but the relationship between personality and specific structural features of music has not been explored. The current study explores the influence of personality and trait empathy on dancers' responsiveness to small tempo differences between otherwise musically identical stimuli, measured by difference in the amount in acceleration of key joints. Thirty participants were recorded using motion capture while dancing to excerpts from six popular songs that were time-stretched to be slightly faster or slower than their original tempi. Analysis revealed that higher conscientiousness and lower extraversion both correlated with greater responsiveness to tempo change. Partial correlation analysis revealed that conscientiousness remained significantly correlated with responsiveness when extraversion was controlled, but not vice versa. No effect of empathy was found. Implications are discussed.

    In this article, I address what kinds of claims are of the right kind to ground conscientious refusals. Specifically, I investigate what conceptions of moral responsibility and moral wrongness can be permissibly presumed by conscientious objectors. I argue that we must permit HCPs to come to their own subjective conclusions about what they take to be morally wrong and what they take themselves to be morally responsible for. However, these subjective assessments of wrongness and responsibility must be constrained in several important ways: they cannot involve empirical falsehoods, objectionably discriminatory attitudes, or unreasonable normative beliefs. I argue that the sources of these constraints are the basic epistemic, relational, and normative competencies needed to function as a minimally decent health-care professional. Finally, I consider practical implications for my framework, and argue that it shows us that the objection raised by the plaintiffs in Zubik v. Burwell is of the wrong sort. © 2017 John Wiley & Sons Ltd.

  4. Conscientious objection: personal and professional ethics in the public square.

    Montgomery, Jonathan

    2015-01-01

    English law expects health professionals to have, and act upon, consciences, but formal conscience clauses are not the main legal recognition of this expectation. Rather, they should be regarded as an anomaly with roots in very specific political settlements between society and health professions, whose legitimacy is historically contingent, and as an aspect of the 'price' to be paid for securing services. There are sound reasons for the protection of conscientious discretion as an aspect of professional identify, but specific rights of personal conscientious objection are difficult to reconcile with legitimate public expectations of comprehensive and non-discriminatory services. Professional identities include moral commitments, such as the privileging of patient safety over administrative convenience. These should not be permitted to be overridden by personal moralities during the course of service delivery (as opposed to debating in the abstract what the proper courses of action should be). Consequently, formal conscientious objection clauses should be reduced to a minimum and regularly revisited. It is generally more satisfactory to address clashes between the personal moralities of professionals and public expectations through more flexible means, enabling accommodation of a plurality of views where possible but acknowledging that this is a matter of striking an appropriate balance. Employment law rather than healthcare law provides the best mechanism for regulating this process.

    This study explored the impact of personality traits on driving safety in high-speed railway drivers. A sample of high-speed railway drivers in Beijing (N=214) completed a questionnaire, including information on personality traits and background variables. The NEO Five Factor Inventory (NEO-FFI) was administered to characterize participants based on five personality traits: Neuroticism, Extraversion, Agreeableness, Openness to Experience, and Conscientiousness. The survey data were combined with naturalistic data of accident involvement and risky driving behavior in China. Poisson regression results show that drivers with high Conscientiousness and Extraversion caused fewer accidents. Higher Conscientiousness and lower Agreeableness were related to less frequent risky driving behavior. Education level and age negatively moderated the relation between certain personality traits and driving safety. The findings suggest that personality traits should be considered when selecting and training high-speed railway drivers.

  6. Conscientious Objection: Understanding the Right of Conscience in Health and Healthcare Practice.

    2016-04-01

    In situations of moral gravitas, healthcare professionals are largely protected in the Western world to invoke their right to conscientiously object to providing care that conflicts with their personal, moral, and religious beliefs. However, making a conscientious objection needs to be predicated by an understanding of conscience, and knowledge of conscience is largely absent in definition as well as discourse surrounding conscientious objection in healthcare practice. Moreover, current definitions of health do not place emphasis on the ethical well-being of patients as well as care providers. Exploring health as an ethical condition of wellness in the light of conscientious healthcare provision will be addressed in my paper. I will also discuss how a distance from conscience in conscientious objection could compromise a healthcare professional's right to conscientious objection, if the fundamental, human right to conscience is not protected in the first place, supported by a focus on the importance of health as a state of ethical well-being.

    Although both conscientiousness and domain-specific interest are believed to be major determinants of academic effort, they have rarely been brought together in empirical studies. In the present research, it was hypothesized that both interest and conscientiousness uniquely predict academic effort and statistically interact with each other to predict academic effort. In 4 studies with 2,557, 415, 1,025, and 1,531 students, respectively, conscientiousness and interest meaningfully and uniquely predicted academic effort. In addition, conscientiousness interacted with interest in a compensatory pattern, indicating that conscientiousness is especially important when a student finds a school subject uninteresting and that domain-specific interest plays a particularly important role for students low in conscientiousness.

    This research estimates models of the importance of conscientiousness for socio-economic outcomes. We use measures of conscientiousness at age 16 to explain adult wages and other outcomes, such as crime, health and savings behaviour. We use several waves from the 1970 British Cohort Study. Our estimates suggest a significant and sizeable correlation between early conscientiousness and adult outcomes. Measurement error is corrected for by applying IV-techniques, errors-in-variables estimators ...

    Although conscientiousness exhibits positive relations with psychological well-being, theoretical and empirical work suggests individuals can be too conscientious, resulting in obsessive-compulsiveness, and therein less positive individual outcomes. However, the potential for curvilinearity between conscientiousness and well-being has been underexplored. We measured 912 subjects on facets of conscientiousness, obsessive-compulsive personality, and well-being variables (life satisfaction, job satisfaction, self-esteem, positive affect, negative affect, work stress). Methods of scoring included traditional sum-scoring, traditional item response theory (IRT), and a relatively new IRT approach. Structural models were estimated to evaluate curvilinearity. Results confirmed the curvilinear relationship between conscientiousness and well-being, and demonstrated that differential facet-level relationships underlie weaker curvilinearity at the general trait level. Consistency was found in the strength of relation between conscientiousness facets with their obsessive-compulsive variants and their contribution to decreased well-being. The most common association was that higher standing on conscientiousness facets was positively related to negative affect. Findings support the idea that extreme standing on facets of conscientiousness more strongly linked to their obsessive-compulsive variants contributed to lower well-being, highlighting the importance of considering alternative functional representations of the relationship between personality and other constructs. Future work should seek to further clarify the link between conscientiousness and negative affect.

  10. The Challenges of Conscientious Objection in Health care.

    Science.gov (United States)

    2016-04-01

    Conscientious objection (CO) is the refusal to perform a legal role or responsibility because of personal beliefs. In health care, conscientious objection involves practitioners not providing certain treatments to their patients, based on reasons of morality or "conscience." The development of conscientious objection among providers is complex and challenging. While there may exist good reasons to accommodate COs of clinical providers, the exercise of rights and beliefs of the provider has an impact on a patient's health and/ or their access to care. For this reason, it is incumbent on the provider with a CO to minimize or eliminate the impact of their CO both on the delivery of care to the patients they serve and on the medical system in which they serve patients. The increasing exercise of CO, and its impact on large segments of the population, is made more complex by the provision of government-funded health care benefits by private entities. The result is a blurring of the lines between the public, civic space, where all people and corporate entities are expected to have similar rights and responsibilities, and the private space, where personal beliefs and restrictions are expected to be more tolerated. This paper considers the following questions: (1) What are the allowances or limits of the exercise a CO against the rights of a patient to receive care within accept practice? (2) In a society where there exist "private," personal rights and responsibilities, as well as "civil" or public/shared rights and responsibilities, what defines the boundaries of the public, civil, and private space? (3) As providers and patients face the exercise of CO, what roles, responsibilities, and rights do organizations and institutions have in this interaction?

    2010-01-01

    Full Text Available Based on a sample of 350 employees in the telecommunication and telecommunication, we obtained empirical evidence suggesting that while individuals high on conscientiousness tended to react more positively to job scope, individuals high on negative affinity tended to react less positively. Job scope was defined as the extent to which a job required the jobholder to be mentally and physically involved to get it done effectively. Typically, a job characterized by a high job scope would be non-repetitive, would need a great deal of independent thought/action and training, would entail the job holder to keep track of his/her progress, and others. The affirmative results obtained in regard of the moderating roles of personality factors in the present study suggested that job design researchers should further explore individuals’ personality differences in response to job scope.

  13. Conscientious objection in healthcare and the duty to refer.

    Science.gov (United States)

    Cowley, Christopher

    2017-04-01

    Although some healthcare professionals have the legal right to conscientiously object to authorise or perform certain lawful medical services, they have an associated duty to provide the patient with enough information to seek out another professional willing to authorise or provide the service (the 'duty to refer'). Does the duty to refer morally undermine the professional's conscientious objection (CO)? I narrow my discussion to the National Health Service in Britain, and the case of a general practitioner (GP) being asked by a pregnant woman to authorise an abortion. I will be careful not to enter the debate about whether abortion should be legalised, or the debate about whether CO should be permitted-I will take both as given. I defend the objecting GP's duty to refer against those I call the 'conscience absolutists', who would claim that if a state is serious enough in permitting the GP's objection in the first place (as is the UK), then it has to recognise the right to withhold any information about abortion.

    2015-10-22

    Clear associations have emerged between conscientiousness and health behaviours, such that higher levels of conscientiousness are predictive of beneficial health behaviours. This study investigated the conscientiousness-fruit and vegetable consumption relationship and whether behavioural intention mediated this relationship. A large sample of adults (N = 2136) completed an online battery of questionnaires measuring conscientiousness, behavioural intentions to consume fruit and vegetables, together with self-reported behaviour. Correlation analysis revealed that conscientiousness and each of its facets were positively associated with behavioural intention and self-reported behaviour. Hierarchical multiple regression analyses revealed that after controlling for age, gender and education, total conscientiousness, and the facets of responsibility, industriousness, order and virtue predicted self-reported behaviour. Further analysis revealed that in line with the Theory of Planned Behaviour, behavioural intention fully mediated the conscientiousness-fruit and vegetable behaviour relationship. In conclusion, low levels of conscientiousness were found to be associated with lower fruit and vegetable intentions, with the latter also associated with fruit and vegetable consumption.

    Research has demonstrated that conscientious individuals tend to engage in planful problem solving to cope with stressful situations. Likewise, mindful individuals tend to favour approach-based coping and are less likely to engage in avoidant coping strategies. To examine whether conscientiousness and mindfulness determined agentic coping behaviour, hierarchical linear regressions were conducted using data from 602 participants drawn from the National Survey of Midlife Development in the United States (MIDUS) Study II and MIDUS II Biomarker Project. Personality responses were derived from the five-factor model inventory, gathered at a single time-point. Results revealed that conscientiousness predicted problem-focused coping (p conscientiousness and mindfulness may contribute to coping responses in potentially healthful ways, highlighting new evidence regarding the potential protective role of conscientiousness.

    Simple Summary This paper examines the trend of Italian academic faculties in complying with the obligation to inform university students of their right to exercise their conscientious objection to scientific or educational activities involving animals, hereafter written as “animal CO”, as established by Law 413/1993, “Norme sull’obiezione di coscienza alla sperimentazione animale” (“Rules on conscientious objection to animal experimentation”), thereafter “Law 413/1993”. Despite an increasing interest in the principles of animal ethics by the international community, this law is still largely disregarded more than 20 years after its enactment. The Ethics Committees, Animal Welfare Committees, as well as the Italian Ministry of Education, University and Research should preside over and monitor the Universities’ compliance with the duty to disclose animal CO. Abstract In Italy, Law 413/1993 states that public and private Italian Institutions, including academic faculties, are obliged to fully inform workers and students about their right to conscientious objection to scientific or educational activities involving animals, hereafter written as “animal CO”. However, little monitoring on the faculties’ compliance with this law has been performed either by the government or other institutional bodies. Based on this premise, the authors have critically reviewed the existing data and compared them with those emerging from their own investigation to discuss limitations and inconsistencies. The results of this investigation revealed that less than half of Italian academic faculties comply with their duty to inform on animal CO. Non-compliance may substantially affect the right of students to make ethical choices in the field of animal ethics and undermines the fundamental right to express their own freedom of thought. The Italian Ministry of Education, Universities and Research, ethics committees and animal welfare bodies should cooperate to make

  5. Watch-wearing as a marker of conscientiousness

    Jenkins, Rob

    2015-01-01

    Several aspects of an individual’s appearance have been shown to predict personality and related behaviour. While some of these cues are grounded in biology (e.g., the human face), other aspects of a person’s appearance can be actively controlled (e.g., clothing). In this paper, we consider a common fashion accessory, the wristwatch. In an exploratory sample (N > 100) and a confirmatory sample (N > 600), we compared big-five personality traits between individuals who do or do not regularly wear a standard wristwatch. Significantly higher levels of conscientiousness were observed in participants who wore a watch. In a third study (N = 85), watch wearers arrived significantly earlier to appointments in comparison to controls. These results are discussed in relation to enclothed cognition and the rise of wearable technology including smartwatches. PMID:26334540

    2010-01-01

    The current study examined how specific coping strategies mediate the relationship between Conscientiousness (C) and positive affect (PA) in a large, multiethnic sample. Using an internet-based daily diary approach, 366 participants (37.6% Caucasian, 30.6% Asian American, 20.7% Hispanic, 9.1% African American) completed measures that assessed daily stressors, coping strategies used to deal with those stressors, and PA over the course of five days. In addition, participants completed a measure of the Five-Factor Model of Personality. Problem-Focused coping partially mediated the relationship between C and PA. Individuals higher in C used more problem-focused coping, which, in turn, was associated with higher PA. The findings of the current study suggest C serves as a protective factor from stress through its influence on coping strategy selection. Other possible mediators in the C-PA relationship are discussed. PMID:21076634

  7. Two conceptions of conscience and the problem of conscientious objection.

    2017-04-01

    Schuklenk and Smalling argue that it is practically impossible for civic institutions to meet the conditions necessary to ensure that conscientious objection does not conflict with the core principles of liberal democracies. In this response, I propose an alternative definition of conscience to that offered by Schuklenk and Smalling. I discuss what I call the 'traditional' notion of conscience, and contrast this with the existentialist conception of conscience (which I take to be a close cousin of the view targeted by Schuklenk and Smalling). I argue that the traditional notion, grounded in an objective moral order, avoids the criticisms advanced by Schuklenk and Smalling; the existentialist conception, in contrast, does not. I conclude by discussing the benefits and risks of a 'restricted view' of respect for conscience.

    2016-10-01

    Despite considerable pain disparities across the care continuum, pain is an understudied health problem in older ethnic minority groups, such as African Americans. Quality pain measurement is a core task in pain management and a mechanism by which pain disparities may be reduced. Pain measurement includes the methods (e.g., assessment approaches, tools) and metrics that researchers and clinicians use to understand the characteristics of pain. However, there are significant issues and gaps that negatively affect pain measurement in older African Americans. Of concern is insufficient representation in pain research, which impedes the testing and refinement of many standardized self-report, behavioral and surrogate report, physiological, and composite measures of pain. The purposes for this article are to discuss the status of pain measurement and factors that affect our knowledge on pain measurement in older African Americans, and to provide guidance for culturally conscientious pain measurement using the available literature.

    2016-03-01

    It is usual to understand conscientious objection as a doctor’s refusal to perform a legitimate intervention, for subjective personal reasons unrelated to medicine. It is then accepted only by respect to professional autonomy and freedom of beliefs. Understood in that way it would be thus reasonable to limit it, curtail it or delete it, since the objector would not be willing to grant benefits that correspond to his medical profession. This work aims to show exactly the opposite, taking as an example the project of law that pretends to decriminalize abortion in some situations in Chile. Is the objector who defends medical activity relying on ethic codes that seek to preserve the values and principles of our profession.

  12. Medical Assistance in Dying in Canada: An Ethical Analysis of Conscientious and Religious Objections

    Directory of Open Access Journals (Sweden)

    Christie, Timothy

    2016-08-01

    Full Text Available Background: The Supreme Court of Canada (SCC has ruled that the federal government is required to remove the provisions of the Criminal Code of Canada that prohibit medical assistance in dying (MAID. The SCC has stipulated that individual physicians will not be required to provide MAID should they have a religious or conscientious objection. Therefore, the pending legislative response will have to balance the rights of the patients with the rights of physicians, other health care professionals, and objecting institutions. Objective: The objective of this paper is to critically assess, within the Canadian context, the moral probity of individual or institutional objections to MAID that are for either religious or conscientious reasons. Methods: Deontological ethics and the Doctrine of Double Effect. Results: The religious or conscientious objector has conflicting duties, i.e., a duty to respect the “right to life” (section 7 of the Charter and a duty to respect the tenets of his or her religious or conscientious beliefs (protected by section 2 of the Charter. Conclusion: The discussion of religious or conscientious objections to MAID has not explicitly considered the competing duties of the conscientious objector. It has focussed on the fact that a conscientious objection exists and has ignored the normative question of whether the duty to respect one’s conscience or religion supersedes the duty to respect the patient’s right to life.

    The pathways between parenting behaviours, personality and physical health have all been separately studied. Prior research has paid little attention to the indirect effects of personality in the path between parenting behaviours and better health. The purpose of this study was to explore the mediational effects of conscientiousness on the relationships between parental socialisation of responsibility and self-rated health, and to examine potential age differences in this mediational pathway. In total, 736 female and 749 male members across Japan participated in this study. They were divided into three groups by age category: younger-, middle-aged and older-aged. Conscientiousness and health were concurrently rated, while parental socialisation of responsibility was retrospectively assessed. Our analyses revealed that parental socialisation of responsibility is positively associated with conscientiousness and self-rated health, that conscientiousness is positively associated with self-rated health, and that conscientiousness fully mediated the effect of parental socialisation of responsibility on self-rated health. The mediational links were consistent across younger, middle-aged and older-aged cohorts. Our findings suggest that greater parental socialisation of responsibility relates to higher conscientiousness, and consequently healthier adults. These findings imply that parental behaviours could be a plausible target for intervention to foster the development of conscientiousness and better health.

    The paper analyzes conscientious objection by physicians, through the concrete situation of legal abortion in Brazil. It reviews the two main ethical frameworks about conscientious objection in public health, the incompatibility thesis and the integrity thesis, to analyze the reality of legal abortion services in the referral services of the Brazilian public health care system. From these two perspectives, a third perspective is proposed - the justification thesis, to manage the right to conscientious objection among physicians in referral services. This analysis may contribute to the organization of services for legal abortion and to the education of future physicians working in emergency obstetric care.

    Social changes and new technologies have brought new problems in doctor-patient relationships. In many clinical contexts conscientious objection is misused, with negative effects for patients, healthcare professionals and institutions. The paper aims to clarify what conscientious objection means in a plural society based on a deliberative democracy and to show the different ways of understanding this society in order to respect both the ethical reasons of individuals and the compulsory normative framework of the Rule of Law. Furthermore, the paper identifies some clinical settings where conscientious objection is often invoked by healthcare professionals, and points out and analyses the arguments that explain why this appeal for conscientious objection is neither legitimate nor correct. Finally, it provides examples of the legal basis and Spanish jurisprudence, as well as the relevant clinical and ethical literature on this topic.

  17. The BMA's guidance on conscientious objection may be contrary to human rights law.

    Adenitire, John Olusegun

    2017-04-01

    It is argued that the current policy of the British Medical Association (BMA) on conscientious objection is not aligned with recent human rights developments. These grant a right to conscientious objection to doctors in many more circumstances than the very few recognised by the BMA. However, this wide-ranging right may be overridden if the refusal to accommodate the conscientious objection is proportionate. It is shown that it is very likely that it is lawful to refuse to accommodate conscientious objections that would result in discrimination of protected groups. It is still uncertain, however, in what particular circumstances the objection may be lawfully refused, if it poses risks to the health and safety of patients. The BMA's policy has not caught up with these human rights developments and ought to be changed.

  18. How to Allow Conscientious Objection in Medicine While Protecting Patient Rights.

    Science.gov (United States)

    Ancell, Aaron; Sinnott-Armstrong, Walter

    2017-01-01

    Paradigmatic cases of conscientious objection in medicine are those in which a physician refuses to provide a medical service or good because doing so would conflict with that physician's personal moral or religious beliefs. Should such refusals be allowed in medicine? We argue that (1) many conscientious objections to providing certain services must be allowed because they fall within the range of freedom that physicians have to determine which services to offer in their practices; (2) at least some conscientious objections to serving particular groups of patients should be allowed because they are not invidiously discriminatory; and (3) even in cases of invidiously discriminatory conscientious objections, legally prohibiting individual physicians from refusing to serve patients on the basis of such objections is not always the best solution.

    The benefits of living a conscientious life have been demonstrated across multiple domains, and yet, few studies have sought to explain how the positive effects in one area may help explain those in another. The current article considers the possibility that conscientious individuals live healthier lives by virtue of having greater success in their relationships. Using both past research and new findings to support our model, we set forth a framework by which to consider how Conscientiousness affects relationship functioning, which in turn leads to better physical, emotional, and psychological health. In so doing, we also provide a new outlook on the health benefits associated with Conscientiousness, and how these may be conferred by relationship success.

    2014-02-26

    Conscientious objection has spurred impassioned debate in many Western countries. Some Norwegian general practitioners (GPs) refuse to refer for abortion. Little is know about how the GPs carry out their refusals in practice, how they perceive their refusal to fit with their role as professionals, and how refusals impact patients. Empirical data can inform subsequent normative analysis. Qualitative research interviews were conducted with seven GPs, all Christians. Transcripts were analysed using systematic text condensation. Informants displayed a marked ambivalence towards their own refusal practices. Five main topics emerged in the interviews: 1) carrying out conscientious objection in practice, 2) justification for conscientious objection, 3) challenges when relating to colleagues, 4) ambivalence and consistency, 5) effects on the doctor-patient relationship. Norwegian GP conscientious objectors were given to consider both pros and cons when evaluating their refusal practices. They had settled on a practical compromise, the precise form of which would vary, and which was deemed an acceptable middle way between competing interests.

    In this paper, we analyze beam combining and atmospheric propagation of high-power lasers for directed-energy (DE) applications. The large linewidths inherent in high-power fiber and slab lasers cause random phase and intensity fluctuations that occur on subnanosecond time scales. Coherently combining these high-power lasers would involve instruments capable of precise phase control and operation at rates greater than ∼10  GHz. To the best of our knowledge, this technology does not currently exist. This presents a challenging problem when attempting to phase lock high-power lasers that is not encountered when phase locking low-power lasers, for example, at milliwatt power levels. Regardless, we demonstrate that even if instruments are developed that can precisely control the phase of high-power lasers, coherent combining is problematic for DE applications. The dephasing effects of atmospheric turbulence typically encountered in DE applications will degrade the coherent properties of the beam before it reaches the target. Through simulations, we find that coherent beam combining in moderate turbulence and over multikilometer propagation distances has little advantage over incoherent combining. Additionally, in cases of strong turbulence and multikilometer propagation ranges, we find nearly indistinguishable intensity profiles and virtually no difference in the energy on the target between coherently and incoherently combined laser beams. Consequently, we find that coherent beam combining at the transmitter plane is ineffective under typical atmospheric conditions.

    The 7×1 end-pumped combiner employing 105/125 μm multimode fibers as pump fibers is investigated. The theoretical analysis reveals that sufficient taper length and low refractive index of the capillary should be adopted to fabricate high transmission efficiency combiners. Based on the simulation results, we fabricate a 7×1 end-pumped pump combiner with an average transmission efficiency of 98.9% and a total return loss of 1.1‰. The measured internal operating temperature of this combiner indicates it can endure pump power of the order of kilowatts.

  4. Invoking conscientious objection in reproductive health care: evolving issues in Peru, Mexico and Chile.

    As Latin American countries seek to guarantee sexual and reproductive health and rights, opponents of women's rights and reproductive choice have become more strident in their opposition, and are increasingly claiming conscientious objection to providing these services. Conscientious objection must be seen in the context of the rights and interests at stake, including women's health needs and right to self-determination. An analysis of law and policy on conscientious objection in Peru, Mexico and Chile shows that it is being used to erode women's rights, especially where it is construed to have no limits, as in Peru. Conscientious objection must be distinguished from politically-motivated attempts to undermine the law; otherwise, the still fragile re-democratisation processes underway in Latin America may be placed at risk. True conscientious objection requires that a balance be struck between the rights of the objector and the health rights of patients, in this case women. Health care providers are entitled to their beliefs and to have those beliefs accommodated, but it is neither viable nor ethically acceptable for conscientious objectors to exercise this right without regard for the right to health care of others, or for policy and services to be rendered ineffectual because of individual objectors.

  5. Conscientious objection in reproductive health care: Analysis of Pichon and Sajous v. France.

    2008-05-01

    This article explores the issue of conscientious objection invoked by health professionals in the reproductive and sexual health care context and its impact on women's ability to access health services. The right to exercise conscientious objection has been recognized by many international and European scholars as being derived from the right to freedom of thought, conscience and religion. It is not, however, an absolute right. When the exercise of conscientious objection conflicts with other human rights and fundamental freedoms, a balance must be struck between the right to conscientious objection and other affected rights such as the right to respect for private life, the right to equality and non-discrimination, and the right to receive and impart information. Particularly in the reproductive health care context, states that allow health professionals to exercise conscientious objection must accommodate this in such a way that its exercise does not compromise women's access to health services. This article analyses the European Court of Human Rights' decision on admissibility in Pichon and Sajous v. France (2001) and argues that a balancing approach should be applied in cases of conscientious objection in the sexual and reproductive health care context.

  6. Sex ratios in the most-selective elite US undergraduate colleges and universities are consistent with the hypothesis that modern educational systems increasingly select for conscientious personality compared with intelligence.

    The main predictors of examination results and educational achievement in modern societies are intelligence (IQ - or general factor 'g' intelligence) and the personality trait termed 'Conscientiousness' (C). I have previously argued that increased use of continuous assessment (e.g. course work rather than timed and supervised examinations) and increased duration of the educational process implies that modern educational systems have become increasingly selective for the personality trait of Conscientiousness and consequently less selective for IQ. I have tested this prediction (in a preliminary fashion) by looking at the sex ratios in the most selective elite US universities. My two main assumptions are: (1) that a greater proportion of individuals with very high intelligence are men than women, and (2) that women are more conscientious than men. To estimate the proportion of men and women expected at highly-selective schools, I performed demonstration calculations based on three plausible estimates of male and female IQ averages and standard deviations. The expected percentage of men at elite undergraduate colleges (selecting students with IQ above 130 - i.e. in the top 2% of the population) were 66%, 61% and 74%. When these estimates were compared with the sex ratios at 33 elite colleges and universities, only two technical institutes had more than 60% men. Elite US colleges and universities therefore seem to be selecting primarily on the basis of something other than IQ - probably conscientiousness. There is a 'missing population' of very high IQ men who are not being admitted to the most selective and prestigious undergraduate schools, probably because their high school educational qualifications and evaluations are too low. This analysis is therefore consistent with the hypothesis that modern educational systems tend to select more strongly for Conscientiousness than for IQ. The implication is that modern undergraduates at the most-selective US schools are not

    Full Text Available In Italy, Law 413/1993 states that public and private Italian Institutions, including academic faculties, are obliged to fully inform workers and students about their right to conscientious objection to scientific or educational activities involving animals, hereafter written as “animal CO”. However, little monitoring on the faculties’ compliance with this law has been performed either by the government or other institutional bodies. Based on this premise, the authors have critically reviewed the existing data and compared them with those emerging from their own investigation to discuss limitations and inconsistencies. The results of this investigation revealed that less than half of Italian academic faculties comply with their duty to inform on animal CO. Non-compliance may substantially affect the right of students to make ethical choices in the field of animal ethics and undermines the fundamental right to express their own freedom of thought. The Italian Ministry of Education, Universities and Research, ethics committees and animal welfare bodies should cooperate to make faculties respect this law. Further research is needed to better understand the reasons for the current trend, as well as to promote the enforcement of Law 413/1993 with particular regard to information on animal CO.

  9. Conscientious Objection in Healthcare Provision: A New Dimension.

    2016-06-01

    The right to conscientious objection in the provision of healthcare is the subject of a lengthy, heated and controversial debate. Recently, a new dimension was added to this debate by the US Supreme Court's decision in Burwell vs. Hobby Lobby et al. which effectively granted rights to freedom of conscience to private, for-profit corporations. In light of this paradigm shift, we examine one of the most contentious points within this debate, the impact of granting conscience exemptions to healthcare providers on the ability of women to enjoy their rights to reproductive autonomy. We argue that the exemptions demanded by objecting healthcare providers cannot be justified on the liberal, pluralist grounds on which they are based, and impose unjustifiable costs on both individual persons, and society as a whole. In doing so, we draw attention to a worrying trend in healthcare policy in Europe and the United States to undermine women's rights to reproductive autonomy by prioritizing the rights of ideologically motivated service providers to an unjustifiably broad form of freedom of conscience.

  10. Coherent beam combining architectures for high power tapered laser arrays

    Coherent beam combining (CBC) aims at increasing the spatial brightness of lasers. It consists in maintaining a constant phase relationship between different emitters, in order to combine them constructively in one single beam. We have investigated the CBC of an array of five individually-addressable high-power tapered laser diodes at λ = 976 nm, in two architectures: the first one utilizes the self-organization of the lasers in an interferometric extended-cavity, which ensures their mutual coherence; the second one relies on the injection of the emitters by a single-frequency laser diode. In both cases, the coherent combining of the phase-locked beams is ensured on the front side of the array by a transmission diffractive grating with 98% efficiency. The passive phase-locking of the laser bar is obtained up to 5 A (per emitter). An optimization algorithm is implemented to find the proper currents in the five ridge sections that ensured the maximum combined power on the front side. Under these conditions we achieve a maximum combined power of 7.5 W. In the active MOPA configuration, we can increase the currents in the tapered sections up to 6 A and get a combined power of 11.5 W, corresponding to a combining efficiency of 76%. It is limited by the beam quality of the tapered emitters and by fast phase fluctuations between emitters. Still, these results confirm the potential of CBC approaches with tapered lasers to provide a high-power and high-brightness beam, and compare with the current state-of-the-art with laser diodes.

  11. A Defence of Conscientious Objection in Medicine: A Reply to Schuklenk and Savulescu.

    Science.gov (United States)

    Cowley, Christopher

    2016-06-01

    In a recent (2015) Bioethics editorial, Udo Schuklenk argues against allowing Canadian doctors to conscientiously object to any new euthanasia procedures approved by Parliament. In this he follows Julian Savulescu's 2006 BMJ paper which argued for the removal of the conscientious objection clause in the 1967 UK Abortion Act. Both authors advance powerful arguments based on the need for uniformity of service and on analogies with reprehensible kinds of personal exemption. In this article I want to defend the practice of conscientious objection in publicly-funded healthcare systems (such as those of Canada and the UK), at least in the area of abortion and end-of-life care, without entering either of the substantive moral debates about the permissibility of either. My main claim is that Schuklenk and Savulescu have misunderstood the special nature of medicine, and have misunderstood the motivations of the conscientious objectors. However, I acknowledge Schuklenk's point about differential access to lawful services in remote rural areas, and I argue that the health service should expend more to protect conscientious objection while ensuring universal access.

    In a recent article for this journal, Morten Magelssen argues that the right to conscientious objection in healthcare is grounded in the moral integrity of healthcare professionals, a good for both professionals and society. In this paper, I argue that there is no right to conscientious objection in healthcare, at least as Magelssen conceives of it. Magelssen's conception of the right to conscientious objection is too expansive in nature. Although I will assume that there is a right to conscientious objection, it does not extend to objections that are purely religious in nature.(i) Thus, this right is considerably more restricted than Magelssen thinks. In making my case, I draw on John Rawls's later work in arguing for the claim that conscientious objection based on purely religious considerations fails to benefit society in the appropriate way. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  13. The Validity of Conscientiousness Is Overestimated in the Prediction of Job Performance.

    Directory of Open Access Journals (Sweden)

    Sven Kepes

    Full Text Available Sensitivity analyses refer to investigations of the degree to which the results of a meta-analysis remain stable when conditions of the data or the analysis change. To the extent that results remain stable, one can refer to them as robust. Sensitivity analyses are rarely conducted in the organizational science literature. Despite conscientiousness being a valued predictor in employment selection, sensitivity analyses have not been conducted with respect to meta-analytic estimates of the correlation (i.e., validity between conscientiousness and job performance.To address this deficiency, we reanalyzed the largest collection of conscientiousness validity data in the personnel selection literature and conducted a variety of sensitivity analyses.Publication bias analyses demonstrated that the validity of conscientiousness is moderately overestimated (by around 30%; a correlation difference of about .06. The misestimation of the validity appears to be due primarily to suppression of small effects sizes in the journal literature. These inflated validity estimates result in an overestimate of the dollar utility of personnel selection by millions of dollars and should be of considerable concern for organizations.The fields of management and applied psychology seldom conduct sensitivity analyses. Through the use of sensitivity analyses, this paper documents that the existing literature overestimates the validity of conscientiousness in the prediction of job performance. Our data show that effect sizes from journal articles are largely responsible for this overestimation.

    Rankings of countries on mean levels of self-reported Conscientiousness continue to puzzle researchers. Based on the hypothesis that cross-cultural differences in the tendency to prefer extreme response categories of ordinal rating scales over moderate categories can influence the comparability of self-reports, this study investigated possible effects of response style on the mean levels of self-reported Conscientiousness in 22 samples from 20 countries. Extreme and neutral responding were estimated based on respondents' ratings of 30 hypothetical people described in short vignettes. In the vignette ratings, clear cross-sample differences in extreme and neutral responding emerged. These responding style differences were correlated with mean self-reported Conscientiousness scores. Correcting self-reports for extreme and neutral responding changed sample rankings of Conscientiousness, as well as the predictive validities of these rankings for external criteria. The findings suggest that the puzzling country rankings of self-reported Conscientiousness may to some extent result from differences in response styles.

    Establishing the neural bases of individual differences in personality has been an enduring topic of interest. However, while a growing literature has sought to characterize grey matter correlates of personality traits, little attention to date has been focused on regional white matter correlates of personality, especially for the personality traits agreeableness, conscientiousness and openness. To rectify this gap in knowledge we used a large sample (n > 550) of older adults who provided data on both personality (International Personality Item Pool) and white matter tract-specific fractional anisotropy (FA) from diffusion tensor MRI. Results indicated that conscientiousness was associated with greater FA in the left uncinate fasciculus (β = 0.17, P conscientiousness, and neuroticism/emotional stability. We observed an association between left uncinate fasciculus FA and stability (β = 0.27, P conscientiousness. In sum, these results provide novel evidence for links between regional white matter microstructure and key traits of human personality, specifically conscientiousness and the meta-trait, stability. Future research is recommended to replicate and address the causal directions of these associations.

    The aim of this paper is to define a set of proposals to inform European institutions in the regulation of Conscientious Objection to abortion. The board of the European Society of Contraception and Reproductive Health Care (ESC) was informed on the elements that should in the opinion of the authors be included in a future regulation of Conscientious Objection to abortion in Europe. These elements are outlined in this paper and the debate about them could form the basis for recommendations to the international scientific community and the European institutions. As current measures governing the principle of conscientious objection result in negative consequences regarding women's access to sexual and reproductive health services, they should be changed. Healthcare services should adopt measures to guarantee that a woman's right to voluntary abortion is not limited by the practitioner's stance on the principle of conscientious objection. In the countries where conscientious objection is allowed, the regulation must clearly delineate the extent of the duties and the exemptions of professionals based on the principles of established social consensus. The recommendations included in this document specify measures on the rights of women, the rights and duties of the practitioner, the role of institutions and the role of professional associations.

    2013-11-01

    Researchers have suggested that the psychoticism (P) personality dimension of the Eysenck Personality Questionnaire may be largely redundant with the agreeableness (A) and conscientiousness (C) constructs of the five-factor model. Little research has examined the distinctiveness of these constructs. We utilized a multi-wave, multi-method design to examine the ability of C, A, and P to uniquely predict a number of important outcomes amongst high school students. A total of 778 students (391 males, 387 females; mean age 15.41 years.) completed personality measures in Grade 10. Self-reported self-esteem, social support, health-related behaviours, religious values as well as teachers' assessments of students, were collected 1 and 2 years later. A, C, and P were distinctive in their ability to predict these outcomes, after controlling for gender and socio-economic status as well as Grade 10 extraversion, openness, and neuroticism. The individual P items explained unique variance over and above that explained by A and C. It was concluded that P is not merely the opposite of A and C. Implications for interventions are raised.

    2009-12-01

    The present study explored the influence of the Big Five dimensions extroversion and conscientiousness on action control regarding both moderate and vigorous physical activity within the framework of the theory of planned behavior (TPB). Prospective data were available from 186 respondents, who completed measures of intention, cognitive and affective attitude, subjective norm, perceived behavioral control, extroversion, conscientiousness, and physical activity at T1. Four weeks later, physical activity was assessed again. Respondents were grouped into four profiles: nonintenders, successful nonintenders, unsuccessful intenders, and successful intenders. Logistic regression analyses revealed that successful enactment in moderate physical activity was associated with extroversion, subjective norm, and affective attitude, whereas successful enactment in vigorous physical activity was associated with conscientiousness. Findings illustrate the differential role played by personality dimensions and TPB concepts in the explanation of moderate and vigorous physical activity action control.

  2. The Continuum of Conscientiousness: The Antagonistic Interests among Obsessive and Antisocial Personalities

    Directory of Open Access Journals (Sweden)

    Hertler Steven C.

    2014-06-01

    Full Text Available The five factor trait of conscientiousnessis a supertrait, denoting on one hand a pattern of excessive labor, rigidity, orderliness and compulsivity,and on the other hand a pattern of strict rectitude, scrupulosity, dutifulness and morality. In both respects the obsessive-compulsive personality is conscientious; indeed, it has been labeled a disorder of extreme conscientiousness (Widiger et al., 2009. Antisocial personality disorder, in the present paper, is described as occupying the opposite end of the conscientiousness continuum. The antisocial is impulsive rather than compulsive, illicit rather than licit, and furtive rather than forthright.After clinically comparing the obsessive and antisocial personalities, the present paper invokes evolutionary theory to explain their resultant behavioral, ideological, political and demographic differences.

  3. Why medical professionals have no moral claim to conscientious objection accommodation in liberal democracies.

    Science.gov (United States)

    Schuklenk, Udo; Smalling, Ricardo

    2017-04-01

    We describe a number of conscientious objection cases in a liberal Western democracy. These cases strongly suggest that the typical conscientious objector does not object to unreasonable, controversial professional services-involving torture, for instance-but to the provision of professional services that are both uncontroversially legal and that patients are entitled to receive. We analyse the conflict between these patients' access rights and the conscientious objection accommodation demanded by monopoly providers of such healthcare services. It is implausible that professionals who voluntarily join a profession should be endowed with a legal claim not to provide services that are within the scope of the profession's practice and that society expects them to provide. We discuss common counterarguments to this view and reject all of them.

    Moon, H

    2001-06-01

    The author proposes that 2 facets of conscientiousness, duty and achievement striving, affect decision makers in escalation of commitment dilemmas in opposing ways, thus masking the predictive ability of a broad measure of conscientiousness. It is proposed that duty is associated with an other-centered orientation and that achievement striving is associated with a self-centered orientation. Analyses of decisions from 360 respondents showed that duty was associated with a deescalation of commitment, achievement striving was associated with an escalation of commitment, and the broad measure of conscientiousness was unassociated with commitment. The author advocates the utility of understanding potential self-centered versus other-centered aspects of the criterion of interest when conducting personality-based research.

  5. Pupillary response predicts multiple object tracking load, error rate, and conscientiousness, but not inattentional blindness.

    Wright, Timothy J; Boot, Walter R; Morgan, Chelsea S

    2013-09-01

    Research on inattentional blindness (IB) has uncovered few individual difference measures that predict failures to detect an unexpected event. Notably, no clear relationship exists between primary task performance and IB. This is perplexing as better task performance is typically associated with increased effort and should result in fewer spare resources to process the unexpected event. We utilized a psychophysiological measure of effort (pupillary response) to explore whether differences in effort devoted to the primary task (multiple object tracking) are related to IB. Pupillary response was sensitive to tracking load and differences in primary task error rates. Furthermore, pupillary response was a better predictor of conscientiousness than primary task errors; errors were uncorrelated with conscientiousness. Despite being sensitive to task load, individual differences in performance and conscientiousness, pupillary response did not distinguish between those who noticed the unexpected event and those who did not. Results provide converging evidence that effort and primary task engagement may be unrelated to IB.

    Personality traits predict substance use in adolescence, but less is known about prospective substance use in middle age and beyond. Moreover, there is growing interest in how personality change and the multiplicative effects among personality traits relate to substance use. Participants included approximately 4,000 adults aged 25-74 who participated in two waves of the Midlife in the U.S. (MIDUS) study. Higher levels of neuroticism, extraversion, openness, and lower levels of conscientiousness and agreeableness predicted longitudinal substance use. Increases in neuroticism and openness predicted increased substance use while increases in conscientiousness and agreeableness predicted decreased substance use. Higher levels of conscientiousness moderated two of the other trait main effects. Personality, trait change, and interactions among traits reliably forecasted 10-year substance-use behaviors.

  7. Accommodating Conscientious Objection in Medicine-Private Ideological Convictions Must Not Trump Professional Obligations.

    2016-01-01

    The opinion of the American Medical Association (AMA) Council on Ethical and Judicial Affairs (CEJA) on the accommodation of conscientious objectors among medical doctors aims to balance fairly patients' rights of access to care and accommodating doctors' deeply held personal beliefs. Like similar documents, it fails. Patients will not find it persuasive, and neither should they. The lines drawn aim at a reasonable compromise between positions that are not amenable to compromise. They are also largely arbitrary. This article explains why that is the case. The view that conscientious objection accommodation has no place in modern medicine is defended.

    This study examined the relationship between conscientiousness and mortality over 18 years and whether smoking behavior mediated this relationship. We utilized data from the Veterans Affairs Normative Aging Study on 1349 men who completed the Goldberg (1992) adjectival markers of the Big Five. Over the 18-year follow-up, 547 (41%) participants died. Through proportional hazards modeling in a structural equation modeling framework, we found that higher levels of conscientiousness significantly predicted longer life, and that this effect was mediated by current smoking status at baseline. Methodologically, we also demonstrate the effectiveness of using a structural equation modeling framework to evaluate mediation when using a censored outcome such as mortality.

    2015-01-01

    Background Attention to and perception of physical sensations and somatic states can significantly influence reporting of complaints and symptoms in the context of clinical care and randomized trials. Although anxiety and high neuroticism are known to increase the frequency and severity of complaints, it is not known if other personality dimensions or genes associated with cognitive function or sympathetic tone can influence complaints. Genetic variation in catechol-O-methyltransferase (COMT) is associated with anxiety, personality, pain, and response to placebo treatment. We hypothesized that the association of complaint reporting with personality might be modified by variation in the COMT val158met genotype. Methods We administered a standard 25-item complaint survey weekly over 3-weeks to a convenience sample of 187 irritable bowel syndrome patients enrolled in a placebo intervention trial and conducted a repeated measures analysis. Results We found that complaint severity rating, our primary outcome, was negatively associated with the personality measures of conscientiousness (β = −0.31 SE 0.11, P = 0.003) and agreeableness (β = −0.38 SE 0.12, P = 0.002) and was positively associated with neuroticism (β = 0.24 SE 0.09, P = 0.005) and anxiety (β = 0.48 SE 0.09, P < 0.0001). We also found a significant interaction effect of COMT met alleles (β = −32.5 SE 14.1, P = 0.021). in patients genotyped for COMT val158met (N  = 87) specifically COMT × conscientiousness (β = 0.73 SE 0.26, P = 0.0042) and COMT × anxiety (β = −0.42 SE 0.16, P = 0.0078) interaction effects. Conclusion These findings potentially broaden our understanding of the factors underlying clinical complaints to include the personality dimension of conscientiousness and its modification by COMT.

  13. Abortion: at the still point of the turning conscientious objection debate.

    Science.gov (United States)

    Bedford, Elliott Louis

    2012-06-01

    Abortion is the central issue in the conscientious objection debate. In this article I demonstrate why this is so for two philosophical viewpoints prominent in American culture. One, represented by Patrick Lee and Robert P. George, holds that the fundamental moral value of being human can be found in bare life and the other, represented by Tom Beauchamp and James Childress, holds that this fundamental value is found in the life that can choose and determine itself. First, I articulate Lee and George's philosophical theory and demonstrate how the fundamental moral value of their theory, personhood, is represented in the issue of abortion. Second, I examine Beauchamp and Childress' theoretical vision and demonstrate how their fundamental moral value, the right to autonomous self-determination, is represented in abortion. Third, I sketch the theoretical and practical dynamics of the conscientious objection debate as well as each author's understanding of conscience. Fourth, I demonstrate how abortion, which represents their respective fundamental value, shapes each perspectives' approach to the conscientious objection debate. I conclude that because each theory finds its fundamental value represented in the issue of abortion, each perspective is bound to engage the conscientious objection debate in a way that centers on the issue of abortion.

  14. Conscientious objection or fear of social stigma and unawareness of ethical obligations.

    Science.gov (United States)

    Faúndes, Anibal; Duarte, Graciana Alves; Osis, Maria José Duarte

    2013-12-01

    Conscientious objection is a legitimate right of physicians to reject the practice of actions that violate their ethical or moral principles. The application of that principle is being used in many countries as a justification to deny safe abortion care to women who have the legal right to have access to safe termination of pregnancy. The problem is that, often, this concept is abused by physicians who camouflage under the guise of conscientious objection their fear of experiencing discrimination and social stigma if they perform legal abortions. These colleagues seem to ignore the ethical principle that the primary conscientious duty of OB/GYNs is-at all times-to treat, or provide benefit and prevent harm to, the patients for whose care they are responsible. Any conscientious objection to treating a patient is secondary to this primary duty. One of the jobs of the FIGO Working Group for the Prevention of Unsafe Abortion is to change this paradigm and make our colleagues proud of providing legal abortion services that protect women's life and health, and concerned about disrespecting the human rights of women and professional ethical principles.

    2014-12-01

    Full Text Available Objective: This study is aimed at examining the mediating role of personality trait of conscientiousness in the relationship between attitudes towards addiction (which is considered to be a barrier to educational achievement and students’ academic performance. Method: As a cross sectional study lying within the range of descriptive studies, 106 students of Guilan University of medical sciences in 2010-2011 were randomly selected as the study sample and responded to the items of subscale conscientiousnessof NEO Personality Inventory and attitude measurement questionnaire toward addiction. Recent acquired total averages of students were considered as academic performance. Findings: In the first step, the academic performance regression was significant aboard tendency towards addiction. In the second step, however, with entry of conscientiousness as a mediator variable , there was observed a significant decrease in the β coefficient of attitude toward addiction and lost its significance. In other words, the mediator variable, consciousness, plays a mediating part in the relationship between tendency to addiction and educational performance. In general, these two variables could moderately explain 12% of the variance in academic performance to make the adjustment. Conclusion: Conscientious people enjoy higher achievement and lower degree often tendency toward addiction due to such factors as self-regulation, perseverance, and resistance against harmful impulses. Therefore,the personality trait of conscientiousness can counteract the detrimental effect of attitude toward addiction on academic performance through performing a protective role.

    Chapman, Benjamin P; van Wijngaarden, Edwin; Seplaki, Christopher L; Talbot, Nancy; Duberstein, Paul; Moynihan, Jan

    2011-05-01

    Studies have indicated that personality may be associated with inflammatory markers such as Interleukin (IL)-6. One pathway between personality and IL-6 may be health behaviors and conditions resulting in inflammation, while an alternate pathway involves activation of stress-response systems. In a clinical trial sample of 200 older adults, we examined associations between personality traits at baseline and three measures of IL-6 spanning 34 weeks of follow-up. Results indicate that IL-6 remained very stable over time, and that higher Conscientiousness and Openness were associated with lower IL-6 across the entire 34 week period. Goal striving was the active subcomponent of Conscientiousness, while aesthetic interests was the active subcomponent of Openness in IL-6 associations. Common health behaviors and chronic illness accounted for only a portion of these effects, suggesting that other behavioral and/or physiological processes may also predispose some persons to inflammation. Personality phenotype may provide useful prognostic information for inflammation. Older adults lower in Conscientiousness and Openness constitute a target population for anti-inflammatory interventions. Openness and Conscientiousness predicts 32-week patterns of Interleukin-6 in older persons.

  2. Uncovering curvilinear relationships between conscientiousness and job performance: how theoretically appropriate measurement makes an empirical difference.

    Carter, Nathan T; Dalal, Dev K; Boyce, Anthony S; O'Connell, Matthew S; Kung, Mei-Chuan; Delgado, Kristin M

    2014-07-01

    The personality trait of conscientiousness has seen considerable attention from applied psychologists due to its efficacy for predicting job performance across performance dimensions and occupations. However, recent theoretical and empirical developments have questioned the assumption that more conscientiousness always results in better job performance, suggesting a curvilinear link between the 2. Despite these developments, the results of studies directly testing the idea have been mixed. Here, we propose this link has been obscured by another pervasive assumption known as the dominance model of measurement: that higher scores on traditional personality measures always indicate higher levels of conscientiousness. Recent research suggests dominance models show inferior fit to personality test scores as compared to ideal point models that allow for curvilinear relationships between traits and scores. Using data from 2 different samples of job incumbents, we show the rank-order changes that result from using an ideal point model expose a curvilinear link between conscientiousness and job performance 100% of the time, whereas results using dominance models show mixed results, similar to the current state of the literature. Finally, with an independent cross-validation sample, we show that selection based on predicted performance using ideal point scores results in more favorable objective hiring outcomes. Implications for practice and future research are discussed.

    2015-12-01

    Child maltreatment poses significant risk to the development of callous/unemotional traits as well as risk behaviors such as engaging in violence, having sex with strangers, and binge drinking. In the current study, the indirect pathway from child maltreatment to risk behaviors was examined via callous/unemotional traits; whereas the conscientious personality trait was tested as a moderator of this indirect pathway. Young adults and parents (N=361; Mage=19.14, SD=1.44) completed questionnaires on child maltreatment histories, callousness/unemotional traits, personality characteristics, and risk behaviors. Structural equation modeling was used to examine the hypothesized direct, indirect and conditional indirect effects. Findings showed indirect links between the child maltreatment latent factor and physical fighting, having sex with strangers, and binge drinking via callous/unemotional traits. Furthermore, the conscientiousness personality type significantly buffered the connection between callous/unemotional traits and physical fighting, supporting a conditional indirect effects. Callous/unemotional traits are important factors in the underlying mechanism between child maltreatment and risk behaviors among young adults, and conscientiousness serves as a protective factor against violence. Preventive intervention programs and clinicians may benefit from focusing in addressing callous/unemotional traits among youth who report childhood maltreatment experiences as well as targeting conscientiousness as a protective factor.

    1977-07-26

    A combination spindle-drive is provided for fabrication of optical quality surface finishes. Both the spindle-and-drive utilize the spindle bearings for support, thereby removing the conventional drive-means bearings as a source of vibration. An airbearing spindle is modified to carry at the drive end a highly conductive cup-shaped rotor which is aligned with a stationary stator to produce torque in the cup-shaped rotor through the reaction of eddy currents induced in the rotor. This arrangement eliminates magnetic attraction forces and all force is in the form of torque on the cup-shaped rotor.

  7. High resolution gravity models combining terrestrial and satellite data

    Rapp, Richard H.; Pavlis, Nikolaos K.; Wang, Yan M.

    1992-01-01

    Spherical harmonic expansions to degree 360 have been developed that combine satellite potential coefficient information, terrestrial gravity data, satellite altimeter information as a direct tracking data type and topographic information. These models define improved representations of the Earth's gravitational potential beyond that available from just satellite or terrestrial data. The development of the degree 360 models, however, does not imply a uniform accuracy in the determination of the gravity field as numerous geographic areas are devoid of terrestrial data or the resolution of such data is limited to, for example, 100 km. This paper will consider theoretical and numerical questions related to the combination of the various data types. Various models of the combination process are discussed with a discussion of various correction terms for the different models. Various sources of gravity data will be described. The new OSU91 360 model will be discussed with comparisons made to previous 360 models and to other potential coefficient models that are complete to degree 50. Future directions in high degree potential coefficient models will be discussed.

  8. Specifying Associations Between Conscientiousness and Executive Functioning: Mental Set Shifting, Not Prepotent Response Inhibition or Working Memory Updating.

    2016-06-01

    Conscientiousness is characterized by self-control, organization, and goal orientation and is positively related to a number of health and professional outcomes. Thus, it is commonly suggested that conscientiousness should be related to superior executive functioning (EF) abilities, especially prepotent response inhibition. However, little empirical support for this notion has emerged, perhaps due to oversimplified and underspecified modeling of EF. The current study sought to fill this gap by testing relations between conscientiousness and three facets of EF using a nested factors latent variable approach. Participants (N = 420; Mage  = 22.5; 50% male; 91% Caucasian) completed a measure of conscientiousness and nine EF tasks designed to tap three related yet distinguishable facets of EF: working memory updating, mental set shifting, and prepotent response inhibition. Structural equation models showed that conscientiousness is positively associated with the EF facet of mental set shifting but not response inhibition or working memory updating. Despite the common notion that conscientiousness is associated with cognitive abilities related to rigid control over impulses (i.e., inhibition), the current results suggest the cognitive ability most associated with conscientiousness is characterized by flexibility and the ability to adapt to changing environmental contingencies and task demands.

    Chung, Si-Yin; Houska, Milan; Reed, Shawndrika

    2013-12-01

    Polyphenol oxidase (PPO) has been shown to reduce major peanut allergens. Since high pressure (HP) can increase enzyme activity, we postulated that further reduction of peanut allergens can be achieved through HP combined with PPO. Peanut extracts containing caffeic acid were treated with each of the following: (1) HP; (2) HP+PPO; (3) PPO; and (4) none. HP was conducted at 300 and 500 MPa, each for 3 and 10 min, 37 °C. After treatment, SDS-PAGE was performed and allergenic capacity (IgE binding) was determined colorimetrically in inhibition enzyme-linked immunosorbent assay and Western blots, using a pooled plasma from peanut-allergic patients. Data showed that HP alone had no effect on major peanut allergens. However, HP at 500 MPa combined with PPO (HP500/PPO) induced a higher (approximately twofold) reduction of major peanut allergens and IgE binding than PPO alone or HP300/PPO. There was no difference between treatment times. We concluded that HP500/PPO at 3-min enhanced a twofold reduction of the allergenic capacity of peanut extracts, as compared to PPO itself.

  11. Reactive high power impulse magnetron sputtering: combining simulation and experiment

    Science.gov (United States)

    Kozak, Tomas; Vlcek, Jaroslav

    2016-09-01

    Reactive high-power impulse magnetron sputtering (HiPIMS) has recently been used for preparation of various oxide films with high application potential, such as TiO2, ZrO2, Ta2O5, HfO2, VO2. Using our patented method of pulsed reactive gas flow control with an optimized reactive gas inlet, we achieved significantly higher deposition rates compared to typical continuous dc magnetron depositions. We have developed a time-dependent model of the reactive HiPIMS. The model includes a depth-resolved description of the sputtered target (featuring sputtering, implantation and knock-on implantation processes) and a parametric description of the discharge plasma (dissociation of reactive gas, ionization and return of sputtered atoms and gas rarefaction). The model uses a combination of experimental and simulation data as input. We have calculated the composition of the target and substrate for several deposition conditions. The simulations predict a reduced compound coverage of the target in HiPIMS compared to the continuous dc sputtering regime which explains the increased deposition rate. The simulations show that an increased dissociation of oxygen in a HiPIMS discharge is beneficial to achieve stoichiometric films on the substrate at high deposition rates.

  12. Ka-Band TWT High-Efficiency Power Combiner for High-Rate Data Transmission

    A four-port magic-T hybrid waveguide junction serves as the central component of a high-efficiency two-way power combiner circuit for transmitting a high-rate phase-modulated digital signal at a carrier frequency in the Ka-band (between 27 and 40 GHz). This power combiner was developed to satisfy a specific requirement to efficiently combine the coherent outputs of two traveling-wavetube (TWT) amplifiers that are typically characterized by power levels on the order of 100 W or more. In this application, the use of a waveguide-based power combiner (instead of a coaxial-cable- or microstrip-based power combiner, for example) is dictated by requirements for low loss, high power-handling capability, and broadband response. Combiner efficiencies were typically 90 percent or more over both the linear and saturated output power regions of operation of the TWTs . Figure 1 depicts the basic configuration of the magic-T hybrid junction. The coherent outputs of the two TWTs enter through ports 1 and 4. As a result of the orientations of the electromagnetic fields, which also provides a needed high port-to-port isolation, of these two input signals and the interior design of the magic-T junction, the input powers are divided so as to add in phase at one output port (port 2), and to be opposite in phase and hence cancel each other at the opposite coplanar output port (port 3). The net result is that the output power at port 2 is essentially double that of the output of one TWT, minus the power lost in the magic-T hybrid junction. Optimum performance as a high-efficiency power combiner thus requires a balance of both power and phase at the input ports of the magic-T. Replicas of this two-way combiner can be arranged in a binary configuration to obtain a 2n-way (where n is an integer) combiner. For example, Figure 2 illustrates the use of three two-way combiners to combine the outputs of four TWTs.

    2017-04-01

    We respond in this paper to various counter arguments advanced against our stance on conscientious objection accommodation. Contra Maclure and Dumont, we show that it is impossible to develop reliable tests for conscientious objectors' claims with regard to the reasonableness of the ideological basis of their convictions, and, indeed, with regard to whether they actually hold they views they claim to hold. We demonstrate furthermore that, within the Canadian legal context, the refusal to accommodate conscientious objectors would not constitute undue hardship for such objectors. We reject concerns that refusing to accommodate conscientious objectors would limit the equality of opportunity for budding professionals holding particular ideological positions. We also clarify various misrepresentations of our views by respondents Symons, Glick and Jotkowitz, and Lyus.

    Full Text Available Previous research on work engagement has mostly examined the relationship of personal resources and work characteristics with work engagement. In this study, the authors focus on the moderating role of one work characteristic, namely workplace mistreatment (i.e., abusive supervision and incivility, on the relationship between a personal resource (i.e., conscientiousness and work engagement dimensions. Using a convenience sample of employees from various organizations, the authors found support for the hypotheses that abusive supervision and incivility moderated the relationship between conscientiousness and work engagement. Specifically, the relationship between conscientiousness and two work engagement dimensions (dedication and absorption is weaker for employees experiencing abusive supervision, whereas the relationship between conscientiousness and two work engagement dimensions (vigor and dedication is weaker for employees experiencing incivility.

    This article analyzes the problem of complicity in wrongdoing in the case of healthcare practitioners (and in particular Roman Catholic ones) who refuse to perform abortions, but who are nonetheless required to facilitate abortions by informing their patients about this option and by referring them to a willing colleague. Although this solution is widely supported in the literature and is also widely represented in much legislation, the argument here is that it fails to both (1) safeguard the well-being of the patients, and (2) protect the moral integrity of healthcare practitioners. Finally, the article proposes a new solution to this problem that is based on a desirable ratio of conscientious objectors to non-conscientious objectors in a hospital or in a given geographic area.

    2014-12-11

    Conscientious Objection or conscientious refusal (CO) in access to reproductive health care is at the center of current legal debates worldwide. In countries such as the US and the UK, constitutional dilemmas surrounding CO in the context of reproductive health services reveal inadequate policy frameworks for balancing CO rights with women's rights to access contraception and abortion. The Colombian Constitutional Court's holistic jurisprudence regarding CO standards has applied international human rights norms so as to not only protect women's reproductive rights as fundamental rights, but to also introduce clear limits for the exercise of CO in health care settings. This paper reviews Latin American lines of regulation in Argentina, Uruguay, and Mexico City to argue that the Colombian Court's jurisprudence offers a strong guidance for future comprehensive policy approaches that aim to effectively balance tensions between CO and women's reproductive rights.

    2013-12-01

    The current study examined the bivariate and multivariate associations of personality with Body Mass Index (BMI) and several eating behavior inventories, focusing on facets of Neuroticism, Conscientiousness, and Impulsivity. Simultaneous multiple regressions showed that the facets Traditionalism, Urgency, and low Vulnerability were significant predictors of BMI. A factor analysis of the eating behavior scales revealed two dimensions: (a) Food and Body Preoccupation and (b) Cued Eating; Neuroticism, low Conscientiousness, and Perfectionism were significant predictors of both eating behavior factors. In addition, the Depression facet predicted Food and Body Preoccupation, and low Temperance predicted Cued Eating. Implications are discussed for the structure of eating pathology and the specificity of facet traits to eating behaviors and obesity.

    2012-11-01

    Considering a growing nurse shortage and the need for qualified nurses to handle increasingly complex patient care situations, how ethical beliefs are influenced and the consequences that can occur when moral conflicts of right and wrong arise need to be explored. The aim of this study was to explore influencers identified by nurses as having the most impact on the development of their ethical beliefs and whether these influencers might impact levels of moral distress and the potential for conscientious objection. Nurses whose ethical beliefs were most influenced by their religious beliefs scored higher in levels of moral distress and demonstrated greater differences in areas of conscientious objection than did nurses who developed their ethical beliefs from influencers such as family values, life and work experience, political views or the professional code of ethics.

    Theory suggests that personality traits evolved to have costs and benefits, with the effectiveness of a trait dependent on how these costs and benefits relate to the present circumstances. This suggests that traits that are generally viewed as positive can have a 'dark side' and those generally viewed as negative can have a 'bright side' depending on changes in context. We test this in a sample of 220 UK medical students with respect to associations between the Big 5 personality traits and learning outcomes across the 5 years of a medical degree. The medical degree offers a changing learning context from pre-clinical years (where a more methodical approach to learning is needed) to the clinical years (where more flexible learning is needed, in a more stressful context). We argue that while trait conscientiousness should enhance pre-clinical learning, it has a 'dark side' reducing the acquisition of knowledge in the clinical years. We also suggest that anxiety has a 'bright side' enhancing the acquisition of skills in the clinical years. We also explore if intelligence enhances learning across the medical degree. Using confirmatory factor analysis and structural equation modelling we show that medical skills and knowledge assessed in the pre-clinical and clinical years are psychometrically distinguishable, forming a learning 'backbone', whereby subsequent learning outcomes are predicted by previous ones. Consistent with our predictions conscientiousness enhanced preclinical knowledge acquisition but reduced the acquisition of clinical knowledge and anxiety enhanced the acquisition of clinical skills. We also identified a curvilinear U shaped association between Surgency (extraversion) and pre-clinical knowledge acquisition. Intelligence predicted initial clinical knowledge, and had a positive total indirect effect on clinical knowledge and clinical skill acquisition. For medical selection, this suggests that selecting students high on conscientiousness may be

    2014-01-01

    In Canada, as in many developed countries, healthcare conscientious objection is growing in visibility, if not in incidence. Yet the country's health professional policies on conscientious objection are in disarray. The article reports the results of a comprehensive review of policies relevant to conscientious objection for four Canadian health professions: medicine, nursing, pharmacy and dentistry. Where relevant policies exist in many Canadian provinces, there is much controversy and potential for confusion, due to policy inconsistencies and terminological vagueness. Meanwhile, in Canada's three most northerly territories with significant Aboriginal populations, whose already precarious health is influenced by funding and practitioner shortages, there are major policy gaps applicable to conscientious objection. In many parts of the country, as a result of health professionals' conscientious refusals, access to some legal health services - including but not limited to reproductive health services such as abortion - has been seriously impeded. Although policy reform on conscientious conflicts may be difficult, and may generate strenuous opposition from some professional groups, for the sake of both patients and providers, such policy change must become an urgent priority.

  5. The paradox of conscientious objection and the anemic concept of 'conscience': downplaying the role of moral integrity in health care.

    Science.gov (United States)

    Giubilini, Alberto

    2014-06-01

    Conscientious objection in health care is a form of compromise whereby health care practitioners can refuse to take part in safe, legal, and beneficial medical procedures to which they have a moral opposition (for instance abortion). Arguments in defense of conscientious objection in medicine are usually based on the value of respect for the moral integrity of practitioners. I will show that philosophical arguments in defense of conscientious objection based on respect for such moral integrity are extremely weak and, if taken seriously, lead to consequences that we would not (and should not) accept. I then propose that the best philosophical argument that defenders of conscientious objection in medicine can consistently deploy is one that appeals to (some form of) either moral relativism or subjectivism. I suggest that, unless either moral relativism or subjectivism is a valid theory--which is exactly what many defenders of conscientious objection (as well as many others) do not think--the role of moral integrity and conscientious objection in health care should be significantly downplayed and left out of the range of ethically relevant considerations.

    The present study examined whether individuals' personality traits, Neuroticism and Conscientiousness, moderated the relationship between perceived stress and depressive symptoms among U.S. Chinese older adults. Data analysis was based on the Population Study of Chinese Elderly in Chicago (PINE). Three thousand one hundred and fifty-nine Chinese adults aged 60 years and older participated in the PINE study. They completed scales that assessed their personality (ie, Neuroticism and Conscientiousness of the NEO Five-Factor Inventory), perceived stress (the Chinese Perceived Stress Scale), and depressive symptoms (the Patient Health Questionnaire). Perceived stress was positively related to depressive symptoms among U.S. Chinese older adults. No moderation effects were found for Neuroticism. Conscientiousness significantly moderated the perceived stress-depressive symptom relationship. The positive relationship between perceived stress and depressive symptoms was weaker for people who were higher in Conscientiousness than those who were lower in Conscientiousness. Conscientiousness mitigated the stress-depressive symptom relationship among U.S. Chinese older adults. Future research is needed to identify the psychological and sociocultural profiles of individuals who show stress resilience and those who are vulnerable. Social services and psychological interventions are needed to promote health and well-being among U.S. Chinese older adults.

  7. The Inevitability of Assessing Reasons in Debates about Conscientious Objection in Medicine.

    Card, Robert F

    2017-01-01

    This article first critically reviews the major philosophical positions in the literature on conscientious objection and finds that they possess significant flaws. A substantial number of these problems stem from the fact that these views fail to assess the reasons offered by medical professionals in support of their objections. This observation is used to motivate the reasonability view, one part of which states: A practitioner who lodges a conscientious refusal must publicly state his or her objection as well as the reasoned basis for the objection and have these subjected to critical evaluation before a conscientious exemption can be granted (the reason-giving requirement). It is then argued that when defenders of the other philosophical views attempt to avoid granting an accommodation to spurious objections based on discrimination, empirically mistaken beliefs, or other unjustified biases, they are implicitly committed to the reason-giving requirement. This article concludes that based on these considerations, a reason-giving position such as the reasonability view possesses a decisive advantage in this debate.

  8. High resolution weak lensing mass mapping combining shear and flexion

    2016-06-01

    Aims: We propose a new mass mapping algorithm, specifically designed to recover small-scale information from a combination of gravitational shear and flexion. Including flexion allows us to supplement the shear on small scales in order to increase the sensitivity to substructures and the overall resolution of the convergence map without relying on strong lensing constraints. Methods: To preserve all available small scale information, we avoid any binning of the irregularly sampled input shear and flexion fields and treat the mass mapping problem as a general ill-posed inverse problem, which is regularised using a robust multi-scale wavelet sparsity prior. The resulting algorithm incorporates redshift, reduced shear, and reduced flexion measurements for individual galaxies and is made highly efficient by the use of fast Fourier estimators. Results: We tested our reconstruction method on a set of realistic weak lensing simulations corresponding to typical HST/ACS cluster observations and demonstrate our ability to recover substructures with the inclusion of flexion, which are otherwise lost if only shear information is used. In particular, we can detect substructures on the 15'' scale well outside of the critical region of the clusters. In addition, flexion also helps to constrain the shape of the central regions of the main dark matter halos. Our mass mapping software, called Glimpse2D, is made freely available at http://www.cosmostat.org/software/glimpse

    We demonstrate 40 W coherently combined output power in a single diffraction-limited beam from a one-dimensional 47-element array of angled-facet slab-coupled optical waveguide amplifiers at 1064 nm. The output from each emitter was collimated and overlapped onto a diffractive optical element combiner using a common transform lens. Phase locking was achieved via active feedback on each amplifier's drive current to maximize the power in the combined beam. The combining efficiency at all current levels was nearly constant at 87%.

    The practice of conscientious objection often arises in the area of individuals refusing to fulfil compulsory military service requirements and is based on the right to freedom of thought, conscience and religion as protected by national, international and regional human rights law. The practice of conscientious objection also arises in the field of health care, when individual health care providers or institutions refuse to provide certain health services based on religious, moral or philosophical objections. The use of conscientious objection by health care providers to reproductive health care services, including abortion, contraceptive prescriptions, and prenatal tests, among other services is a growing phenomena throughout Europe. However, despite recent progress from the European Court of Human Rights on this issue (RR v. Poland, 2011), countries and international and regional bodies generally have failed to comprehensively and effectively regulate this practice, denying many women reproductive health care services they are legally entitled to receive. The Italian Ministry of Health reported that in 2008 nearly 70% of gynaecologists in Italy refuse to perform abortions on moral grounds. It found that between 2003 and 2007 the number of gynaecologists invoking conscientious objection in their refusal to perform an abortion rose from 58.7 percent to 69.2 percent. Italy is not alone in Europe, for example, the practice is prevalent in Poland, Slovakia, and is growing in the United Kingdom. This article outlines the international and regional human rights obligations and medical standards on this issue, and highlights some of the main gaps in these standards. It illustrates how European countries regulate or fail to regulate conscientious objection and how these regulations are working in practice, including examples of jurisprudence from national level courts and cases before the European Court of Human Rights. Finally, the article will provide recommendations

  14. Why it is 'better' to be reliable but dumb than smart but slapdash: are intelligence (IQ) and Conscientiousness best regarded as gifts or virtues.

    Science.gov (United States)

    Charlton, Bruce G

    2009-10-01

    The psychological attributes of intelligence and personality are usually seen as being quite distinct in nature: higher intelligence being regarded a 'gift' (bestowed mostly by heredity); while personality or 'character' is morally evaluated by others, on the assumption that it is mostly a consequence of choice? So a teacher is more likely to praise a child for their highly Conscientious personality (high 'C')--an ability to take the long view, work hard with self-discipline and persevere in the face of difficulty--than for possessing high IQ. Even in science, where high intelligence is greatly valued, it is seen as being more virtuous to be a reliable and steady worker. Yet it is probable that both IQ and personality traits (such as high-C) are about-equally inherited 'gifts' (heritability of both likely to be in excess of 0.5). Rankings of both IQ and C are generally stable throughout life (although absolute levels of both will typically increase throughout the lifespan, with IQ peaking in late-teens and C probably peaking in middle age). Furthermore, high IQ is not just an ability to be used only as required; higher IQ also carries various behavioural predispositions--as reflected in the positive correlation with the personality trait of Openness to Experience; and characteristically 'left-wing' or 'enlightened' socio-political values among high IQ individuals. However, IQ is 'effortless' while high-C emerges mainly in tough situations where exceptional effort is required. So we probably tend to regard personality in moral terms because this fits with a social system that provides incentives for virtuous behaviour (including Conscientiousness). In conclusion, high IQ should probably more often be regarded in morally evaluative terms because it is associated with behavioural predispositions; while C should probably be interpreted with more emphasis on its being a gift or natural ability. In particular, people with high levels of C are very lucky in modern

    OPV cell efficiencies have increased significantly over the last decade and verified champion efficiencies are currently at 8.3% for both single and multi-junction device types. These increases in efficiency have been driven through the development and optimization of the donor and acceptor materials in bulk heterojunction active layers. Plextronics and Solarmer Energy Inc. are two of the world leading developers of these donor and acceptor materials. Solarmer Energy has reported NREL certified 6.77% efficiencies using optimized low band gap donor materials in combination with PC61BM and PC71BM acceptors and recently reported a champion NREL certified efficiency of 8.1%. Plextronics has reported Newport certified efficiencies of 6.7% using PC71BM acceptors with low band gap materials. In addition, Plextronics has also demonstrated that OPV efficiency of P3HT based materials can be improved by 50% by improving the Voc using alternative acceptors (indene substituted C60 and C70) to PC61BM and PC71BM. However, performance of these alternative acceptors in combination with low band gap materials has not been investigated and the potential for efficiency improvement is evident. In this collaboration, four low band gap donor materials from Solarmer Energy Inc were combined with Plextronics’ indene-class acceptors Plextronics’ indene substituted C60 and C70 acceptors to demonstrate OPV performance greater than 7%. Two main indene class C60 acceptors (codenamed Mono-indene[C60] Mono-indene[C60] , Bis-indene[C60] ) were screened with the Solarmer polymers. These four polymers were screened and optimized with the indene class acceptors at both Plextronics and Solarmer. A combination was identified which produced 6.7% (internal measurement) with a Solarmer polymer and a Plextronics fullerene acceptor. This was accomplished primarily by improving the Voc as well as improving the current (Jsc) and FF.

    The study of NAFLD in humans has several limitations. Using murine models helps to understand disease pathogenesis. Evaluate the impact of 4 different diets in the production of NAFLD with emphasis on a combined high-fat plus sustained high sucrose consumption. Eight week-old male Wistar rats were divided in four groups and fed for 90 days with the following diets: 1) Control chow diet (C); 2) High-fat cholesterol diet (HFC) + 5% sucrose in drinking water. 3) High-fat cornstarch diet (HFCO) + 5% sucrose in drinking water. 4) Chow diet + 20% sucrose in drinking water (HSD). Metabolic changes, leptin levels, liver histology, hepatic and plasma lipid composition, fasting plasma glucose and insulin and liver gene expression of FAS, SREBP-1 and PPAR-α were evaluated. The HFC diet had the highest grade of steatosis (grade 2 of 3) and HSD showed also steatosis (grade 1). Liver weight TG and colesterol concentrations in liver were greater in the HFC diet. There were no increased levels of iron in the liver. Rats in HFC gained significantly more weight (P < 0.001). All experimental groups showed fasting hyperglycemia. HFC had the highest glucose level (158.5 ± 7 mg/dL) (P < 0.005). The HSD and the HFCO diets developed also hyperglycemia. HSD had significantly higher fasting hyperinsulinemia. Serum leptin was higher in the HFC diet (p = 0.001). In conclusion, the HFC diet with combination of high fat and high sucrose is more effective in producing NAFLD compared with a high sucrose diet only.

    Laboratory classes in which animals are seriously harmed or killed, or which use cadavers or body parts from ethically debatable sources, are controversial within veterinary and other biomedical curricula. Along with the development of more humane teaching methods, this has increasingly led to objections to participation in harmful animal use. Such cases raise a host of issues of importance to universities, including those pertaining to curricular design and course accreditation, and compliance with applicable animal welfare and antidiscrimination legislation. Accordingly, after detailed investigation, some universities have implemented formal policies to guide faculty responses to such cases, and to ensure that decisions are consistent and defensible from legal and other policy perspectives. However, many other institutions have not yet done so, instead dealing with such cases on an ad hoc basis as they arise. Among other undesirable outcomes this can lead to insufficient student and faculty preparation, suboptimal and inconsistent responses, and greater likelihood of legal challenge. Accordingly, this paper provides pertinent information about the evolution of conscientious objection policies within Australian veterinary schools, and about the jurisprudential bases for conscientious objection within Australia and the USA. It concludes with recommendations for the development and implementation of policy within this arena.

    The Chilean bill that regulates abortion for three cases (Bulletin Nº 9895-11) includes the possibility that health professionals may manifest their conscientious objection (CO) to perform this procedure. Due to the broad impact that the issue of C O had, the Ethics Department of the Chilean College of Physicians considered important to review this concept and its ethical and legal basis, especially in the field of sexual and reproductive health. In the present document, we define the practical limit s of CO, both for the proper fulfillment of the medical profession obligations, and for the due respect and non-discrimination that the professional objector deserves. We analyze the denial of some health institutions to perform abortions if it is legalize d, and we end with recommendations adjusted to the Chilean reality. Specifically, we recognize the right to conscientious objection that all physicians who directly participate in a professional act have. But we a lso recognize that physicians have ineludib le obligations towards their patients, including the obligation to inform about the existence of this service, how to access to it and -as set out in our code of ethics- to ensure that another colleague will continue attending the patient.

  20. Selling conscience short: a response to Schuklenk and Smalling on conscientious objections by medical professionals.

    Maclure, Jocelyn; Dumont, Isabelle

    2017-04-01

    In a thought-provoking paper, Schuklenk and Smalling argue that no right to conscientious objection should be granted to medical professionals. First, they hold that it is impossible to assess either the truth of conscience-based claims or the sincerity of the objectors. Second, even a fettered right to conscientious refusal inevitably has adverse effects on the rights of patients. We argue that the main problem with their position is that it is not derived from a broader reflection on the meaning and implications of freedom of conscience and reasonable accommodation. We point out that they collapse two related but distinct questions, that is, the subjective conception of freedom of conscience and the sincerity test. We note that they do not successfully show that the standard norm according to which exemption claims should not impose undue hardship on others is unworkable. We suggest that the main reason why arguments such as no one is forced to be a medical professional are flawed is that public norms should not constrain citizens to choose between two of their basic rights unless it is necessary. In fine, Schuklenk and Smalling, who see conscience claims as arbitrary dislikes, sell freedom of conscience short and forego any attempts at balancing the competing rights involved. We maintain the authors neglect that most of legal reasoning is contextual and that the blanket restriction of healthcare professionals' freedom of conscience is disproportionate.

  1. Can you have your meat and eat it too? Conscientious omnivores, vegetarians, and adherence to diet.

    2015-01-01

    As criticisms of factory farming continue to mount, an increasing number of individuals have changed their existing dietary practices. Perhaps the two most important food movements reacting against industrial farming are (1) vegetarianism, the avoidance of animal flesh; and (2) conscientious omnivorism (CO), the consumption of meat or fish only when it satisfies certain ethical standards. While the former group has been well-studied in the social science literature, there have been few, if any, studies specifically examining those who identify themselves as ethical meat eaters. The present research sought to determine if one particular diet was more greatly adhered to by its followers. Results revealed that COs were less likely to perceive their diet as something that they absolutely needed to follow, reported violating their diet more, felt less guilty when doing so, believed less in animal rights, were less disgusted by factory-farmed meat, rated its sensory characteristics more favorably, and were lower in ingroup identification than vegetarians. Mediation analysis demonstrated that differences in the amount of violations and guilt associated with these violations could in part be traced to practical and psychological factors, making it more difficult to follow conscientious omnivorism.

    The need to develop effective tools to measure professionalism continues to challenge medical educators; thus, as a follow-up to a recent examination of the "Conscientiousness Index" (CI, a novel measure of one facet of professionalism) in one setting with preclinical medical students, the authors aimed to investigate the validity of the CI as a proxy measure of professionalism in a different context and in the clinical phase of undergraduate medical education. In academic year 2009-2010, the authors collected data similar to those collected for the original preclinical study. In an effort to create a Clinical Conscientiousness Index (CCI) score, they collected the following information on 124 third-year medical students completing their clinical rotations: attendance, timeliness of assessment submissions, and completion of rotation evaluations. Then, they compared the resultant CCI scores with faculty views on professionalism and with formal assessments of students' professionalism (i.e., their portfolios and objective structured clinical examinations [OSCEs]). The authors demonstrate significant correlations between CCI scores and faculty views on professionalism (rS = 0.3; P = .001), and between CCI scores and OSCE score (rS = 0.237; P = .008), but not between CCI scores and portfolio assessment (rS = 0.084; P = .354). The authors also present relationships between CCI scores and demographics. The CCI is a practical, valid proxy measure of professionalism, achieving good correlation with faculty views on professionalism and clinical competency examinations, but not portfolio assessment, in one clinical undergraduate setting.

    A highly efficient nano-periodical grating is theoretically investigated for spectral beam combining (SBC) and is experimentally implemented for attaining high-brightness laser from a diode laser array. The rigorous coupled-wave analysis with the S matrix method is employed to optimize the parameters of the grating. According the optimized parameters, the grating is fabricated and plays a key role in SBC cavity. The diffraction efficiency of this grating is optimized to 95% for the output laser which is emitted from the diode laser array. The beam parameter product of 3.8 mm mrad of the diode laser array after SBC is achieved at the output power of 46.3 W. The optical-to-optical efficiency of SBC cavity is measured to be 93.5% at the maximum operating current in the experiment.

    In this paper I defend the Reasonability View: the position that medical professionals seeking a conscientious exemption must state reasons in support of their objection and allow those reasons to be subject to evaluation. Recently, this view has been criticized by Jason Marsh as proposing a standard that is either too difficult to meet or too easy to satisfy. First, I defend the Reasonability View from this proposed dilemma. Then, I develop this view by presenting and explaining some of the central criteria it uses to assess whether a conscientious objection is proper grounds for extending an exemption to a medical practitioner.

    Bioethicists commenting on conscientious objection and abortion should consider the empirical data on abortion providers. Abortion providers do not fall neatly into groups of providers and objectors, and ambivalence is a key theme in their experience. Practical details of abortion services further upset the dichotomy. These empirical facts are important because they demonstrate that the way the issue is described in analytical bioethics does not reflect reality. Addressing conscientious objection as a barrier to patient access requires engaging with those who provide the service and those who are able to but do not. The experiences of doctors facing these decisions potentially challenge and expand our understanding of the issue as an ethical concern.

  7. Combined radiotherapy and chemotherapy for high-grade brain tumours

    Science.gov (United States)

    Barazzuol, Lara

    Glioblastoma (GBM) is the most common primary brain tumour in adults and among the most aggressive of all tumours. For several decades, the standard care of GBM was surgical resection followed by radiotherapy alone. In 2005, a landmark phase III clinical trial coordinated by the European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) demonstrated the benefit of radiotherapy with concomitant and adjuvant temozolomide (TMZ) chemotherapy. With TMZ, the median life expectancy in optimally managed patients is still only 12-14 months, with only 25% surviving 24 months. There is an urgent need for new therapies in particular in those patients whose tumour has an unmethylated methylguanine methyltransferase gene (MGMT) promoter, which is a predictive factor of benefit from TMZ. In this dissertation, the nature of the interaction between TMZ and radiation is investigated using both a mathematical model, based on in vivo population statistics of survival, and in vitro experimentation on a panel of human GBM cell lines. The results show that TMZ has an additive effect in vitro and that the population-based model may be insufficient in predicting TMZ response. The combination of TMZ with particle therapy is also investigated. Very little preclinical data exists on the effects of charged particles on GBM cell lines as well as on the concomitant application of chemotherapy. In this study, human GBM cells are exposed to 3 MeV protons and 6 MeV alpha particles in concomitance with TMZ. The results suggest that the radiation quality does not affect the nature of the interaction between TMZ and radiation, showing reproducible additive cytotoxicity. Since TMZ and radiation cause DNA damage in cancer cells, there has been increased attention to the use of poly(ADP-ribose) polymerase (PARP) inhibitors. PARP is a family of enzymes that play a key role in the repair of DNA breaks. In this study, a novel PARP inhibitor, ABT-888

    Chronic kidney dysfunction is recognized as a risk factor for atherosclerosis and complicates strategies and treatment. Therefore, it is important for cardiologists not only to detect and measure potential kidney dysfunction, but also to know the mechanisms by which the heart and kidney interact, and recognize that in cases of acute coronary syndrome, the presence of renal dysfunction increases the risk of death. The detection and classification of kidney dysfunction into 5 stages is based on the estimated glomerular filtration rate (GFR). The presence of hypertension, endothelial dysfunction, dyslipidemia, inflammation, activation of the renin-angiotensin system and specific calcifications are the main mechanisms by which renal dysfunction can induce or compound cardiovascular disease. The magnitude of renal dysfunction is related to the cardiovascular risk; a linear relation links the extent of GFR decrease and the risk of cardiovascular events. Renal dysfunction and acute coronary syndromes are a dangerous combination: more common comorbidities, more frequent contraindications for effective drugs and higher numbers of drug-related adverse events such as bleeding partially explain the higher mortality in patients with renal dysfunction. In addition, despite higher risk, patients with renal dysfunction often receive fewer guideline-recommended treatments even in the absence of contraindications. Renal dysfunction induces and promotes atherosclerosis by various pathophysiologic pathways and is associated with other cardiovascular risk factors and underuse of appropriate therapy. Therefore, the assessment of renal function is an important step in the risk evaluation of patients with coronary artery disease.

    We propose a general scenario for moduli stabilization where low-energy supersymmetry can be accommodated with a high scale of inflation. The key ingredient is that the stabilization of the modulus field during and after inflation is not associated with a single, common scale, but relies on two different mechanisms. We illustrate this general scenario in a simple example, where during inflation the modulus is stabilized with a large mass by a Kaehler potential coupling to the field which provides the inflationary vacuum energy via its F-term. After inflation, the modulus is stabilized, for instance, by a KKLT superpotential. (orig.)

  11. Combining Knowledge and Beliefs in High School Climate Science Instruction

    Teachers face a seemingly insurmountable task when asked to address the science of climate change with the general public. This topic is unique because of its complexity, political implications and urgency for action. Developing tools that teachers need to address the National Science Standards begin with comprehensive professional development. After one year's implementation of our program (after participation in UCAR's NASA-funded Research Experiences for Teachers Institute), we are beginning to see evidence that with intentional delivery and preparation of climate science curriculum it is possible to combine knowledge and beliefs in order to nurture a desire for action. Teachers need to acquire an appreciation and understanding for the level of connectedness between disciplines used to study climate and repeatedly present the scientific process as a way of gathering evidence to arrive at factual conclusions. This emphasis on scientific process is important in dealing with the difference between personal beliefs and knowledge. In students' everyday lives their beliefs often matter much more to them than scientific facts. Today's media frequently gives opinions as much clout as verifiable data. Therefore, science teachers need to become anthropologists in order to navigate between cultures, traditions, economic realities and foundational beliefs to effect a change in attitude. Climate change affects us all whether we like it or not, and the challenge is finding a personal connection for each student that supports their journey instead of polarizing each other into the "believers" and "non-believers". It is important to listen to those whose worldview is not best explained by science in order to address the problem with the least resistance. At the end of a program that implemented techniques described above the student's overwhelming response was not: "climate change is a hoax" but instead "ok, I get it, NOW WHAT?" This is the million-dollar question that we

    Full Text Available Using the recently developed SIMS–SPM prototype, secondary ion mass spectrometry (SIMS data was combined with topographical data from the scanning probe microscopy (SPM module for five test structures in order to obtain accurate chemical 3D maps: a polystyrene/polyvinylpyrrolidone (PS/PVP polymer blend, a nickel-based super-alloy, a titanium carbonitride-based cermet, a reticle test structure and Mg(OH2 nanoclusters incorporated inside a polymer matrix. The examples illustrate the potential of this combined approach to track and eliminate artefacts related to inhomogeneities of the sputter rates (caused by samples containing various materials, different phases or having a non-flat surface and inhomogeneities of the secondary ion extraction efficiencies due to local field distortions (caused by topography with high aspect ratios. In this respect, this paper presents the measured relative sputter rates between PVP and PS as well as in between the different phases of the TiCN cermet.

    For Wireless Personal Area Network (WPAN) systems, resource allocation between several users within a piconet and the coexistence of several piconets are very important points to take into consideration for the optimization of high data rate Ultra Wide Band (UWB) systems. To improve the performance of the Multi-Band OFDM (Orthogonal Frequency Division Multiplex) solution proposed by the Multi-Band OFDM Alliance (MBOA), the addition of a spreading component in the frequency domain is a good solution since it makes resource allocation easier and also offers better robustness against channel frequency selectivity and narrowband interference. The Spread Spectrum - Multi-Carrier - Multiple Access (SS-MC-MA) system proposed in this article offers not only the advantages of Multi-Carrier - Coded Division Multiple Access (MC-CDMA) brought by frequency spreading, but also a more effective dynamic resource allocation in a multi-user and multi-piconet context. These improvements are obtained without increasing the compl...

    Aims Vascular complications are the leading cause of mortality and morbidity in patients with diabetes. However, proper animal models of diabetic vasculopathy that recapitulate the accelerated progression of vascular lesions in human are unavailable. In the present study, we developed a zebrafish model of diabetic vascular complications and the methodology for quantifying vascular lesion formation real-time in the living diabetic zebrafish. Methods and Results Wild type zebrafish (AB) and transgenic zebrafish lines of fli1:EGFP, lyz:EGFP, gata1:dsRed, double transgenic zebrafish of gata1:dsRed/fli1:EGFP were exposed to high cholesterol diet and 3% glucose (HCD-HG) for 10 days. The zebrafish model with HCD-HG treatment was characterized by significantly increased tissue levels of insulin, glucagon, glucose, total triglyceride and cholesterol. Confocal microscopic analysis further revealed that the diabetic larvae developed clearly thickened endothelial layers, distinct perivascular lipid depositions, substantial accumulations of inflammatory cells in the injured vasculature, and a decreased velocity of blood flow. Moreover, the vascular abnormalities were improved by the treatment of pioglitazone and metformin. Conclusion A combination of high cholesterol diet and high glucose exposure induces a rapid onset of vascular complications in zebrafish similar to the early atherosclerotic vascular injuries in mammalian diabetic models, suggesting that zebrafish may be used as a novel animal model for diabetic vasculopathy.

    Adolescence represents one of the critical transitions in the life span and is characterized by a tremendous pace in growth and change that is second only to that of infancy. Both biological and psychological changes occurring during early adolescence may also influence the definition of subsequent late adolescence or early adulthood physiological or (psycho)-pathological features, including bulimia nervosa (BN) whenever occurring. Therefore, a pre-emptive assessment of suggestive psychological traits, including bulimic ones, during early and late years of adolescence, is recommended and represents the goal of the present study. Six hundred and eight healthy volunteers attending mid- or high school, aged 14-19 years, were consecutively enrolled at multiple sites in Eastern Sicily, Italy. A systematic psychological assessment was performed, including McCrae and Costa' BigFive, the Eating Disorders Inventory (EDI), Bisantis's Assertivity test and the Liebowitz Social Anxiety Scale for Children and Adolescents. Demographic and general characteristics, including the body mass index, were also recorded. Based on hierarchical considerations, cases were then divided into 'younger' ('early' years, 14-16) and 'older' ('late' years, 17-19) adolescents. Upon descriptive and Pearson's correlation analyses, the following EDI constructs 'drive to thinness' and 'bulimia' scored significantly higher (both p = <.001) in 'early' vs. 'late' cases. Conversely, BigFive 'conscientiousness' was higher in older subjects vs. early cases (p = <.003). As expected, 'drive to thinness' positively correlated with BN both in early (r = .31) and late (r = .50) cases. In the 'late' group, age correlated with conscientiousness (r = .206) while BN correlated with drive to thinness (r = .505); finally, a negative correlation was observed with regard to consciousness and BN (r = -.19). Despite intrinsic methodological limits, our preliminary findings confirm that the

    Combined radiation and conduction heat transfer through various high-temperature, high-porosity, unbonded (loose) fibrous insulations was modeled based on first principles. The diffusion approximation was used for modeling the radiation component of heat transfer in the optically thick insulations. The relevant parameters needed for the heat transfer model were derived from experimental data. Semi-empirical formulations were used to model the solid conduction contribution of heat transfer in fibrous insulations with the relevant parameters inferred from thermal conductivity measurements at cryogenic temperatures in a vacuum. The specific extinction coefficient for radiation heat transfer was obtained from high-temperature steady-state thermal measurements with large temperature gradients maintained across the sample thickness in a vacuum. Standard gas conduction modeling was used in the heat transfer formulation. This heat transfer modeling methodology was applied to silica, two types of alumina, and a zirconia-based fibrous insulation, and to a variation of opacified fibrous insulation (OFI). OFI is a class of insulations manufactured by embedding efficient ceramic opacifiers in various unbonded fibrous insulations to significantly attenuate the radiation component of heat transfer. The heat transfer modeling methodology was validated by comparison with more rigorous analytical solutions and with standard thermal conductivity measurements. The validated heat transfer model is applicable to various densities of these high-porosity insulations as long as the fiber properties are the same (index of refraction, size distribution, orientation, and length). Furthermore, the heat transfer data for these insulations can be obtained at any static pressure in any working gas environment without the need to perform tests in various gases at various pressures.

    2015-04-01

    Recently the scope of protections afforded those healthcare professionals and institutions that refuse to provide certain interventions on the grounds of conscience have expanded, in some instances insulating providers (institutional and individual) from any liability or sanction for harms that patients experience as a result. With the exponential increase in the penetration of Catholic-affiliated healthcare across the country, physicians and nurses who are not practicing Catholics are nevertheless required to execute documents pledging to conform their patient care to the Ethical and Religious Directives for Health Care Services as a condition of employment or medical staff privileges. In some instances, doing so may result in patient morbidity or mortality or violate professional standards for respecting advance directives or surrogate decisionmaking. This article challenges the ethical propriety of such institutional mandates and argues that legal protections for conscientious refusal must provide redress for patients who are harmed by care that falls below the prevailing clinical standards.

  20. Conscientious objection and healthcare in the UK: why tribunals are not the answer.

    Cowley, Christopher

    2016-02-01

    A recent issue of the journal Bioethics discussed whether conscientious objectors within the healthcare context should be required to give their reasons to a specially convened tribunal, who would have the power to reject the objection. This is modeled on the context of military conscription. Advocates for such a tribunal offer two different justifications, one based on determining the genuineness of the applicant's beliefs, the other based on determining their reasonableness. I limit my discussion to a doctor's objection to abortion in the UK, and argue against both justifications: I thereby defend the status quo, where such doctors are not formally required to defend their beliefs. My argument has to do with the particular nature of the abortion debate in the UK, and the more general nature of ethical disagreement.

    Eysenck (1983) has previously proposed biological mechanisms for his three personality dimensions. From a psychometric perspective there has been a growing acceptance of a five-factor model of personality incorporating two of Eysenck's dimensions Extraversion (E) and Neuroticism (N) together with Openness to Experience (O), Agreeableness (A) and Conscientiousness (C). Despite the growing acceptance of the 'Big 5' model of personality there has been very few studies that have examined the biological basis of O, A and C. In an exploratory study we report the correlations between photic driving at alpha, beta-1, beta-2, delta and theta bands and O, A and C from the NEO PI-R in 16 participants. Significant correlations between the EEG at frontal, occipital-parietal and central-temporal areas at different driving frequencies with O, A and C are discussed.

    Full Text Available En las sociedades democráticas la objeción de conciencia a las leyes democráticamente promulgadas es un hecho, tanto a nivel ciudadano como entre los profesionales. El respeto a las leyes es una obligación prima facie en estas sociedades. Pero la justicia democrática debe a su vez respetar la conciencia de las personas porque ella constituye la identidad ética de los individuos. Y ambas, ley y ética son elementos necesarios -ninguno suficiente- para su realización. Desde este prisma se analiza también el problema de la objeción de conciencia de los profesionales de la medicina y se concluye que la objeción no supone un derecho absoluto a la exención de determinadas tareas sino que siempre debe tenerse en cuenta la responsabilidad del profesional y de las instituciones de cara al ciudadano. En esa línea se sugieren soluciones que incidan en la protección bidireccional del profesional y de los ciudadanos.Conscientious objection to democratically accepted laws in democratic societies is a fact, both among citizens and among professionals. Due respect for laws is a prima facie duty in these societies. But democratic justice must at the same time respect peoples’ conscience for it constitutes the ethical identity of individuals. And both law and ethics are necessary - although neither of them is sufficient - for its realization. The problem of conscientious objection among healthcare professionals is analysed from this standpoint and the conclusion is that objection is not an absolute right to exemption from several duties, but that the responsibility of the professional and of the institutions towards the citizenry must always be taken into account. Some solutions are suggested that try to protect both the professionals and the citizens in a bi-directional way.

    A beam combiner, which can combine multiple Gaussian beams into a single one, has many important applications, such as high-power radar and weapon. In this paper, we propose a new scheme of the design of high-power beam combiner at millimeter wavelengths by using wire grids. The design tool is to combine a genetic algorithm (GA) for global optimization and an Ansoft HFSS for rigorous electromagnetic computation. The design method is described in detail and the optimized results are presented. Finally, a brief summary is given.

    High-radiance lasers are desired for many applications in defense and manufacturing. Spectral beam combining (SBC) by volume Bragg gratings (VBGs) is a very promising method for high-radiance lasers that need to achieve 100 kW level power. Laser-induced heating of VBGs under high-power radiation presents a challenge for maintaining Bragg resonance at various power levels without mechanical realignment. A novel thermal tuning technique and apparatus is presented that enables maintaining peak efficiency operation of the SBC system at various power levels without any mechanical adjustment. The method is demonstrated by combining two high-power ytterbium fiber lasers with high efficiency from low power to full combined power of 300 W (1.5 kW effective power), while maintaining peak combining efficiency within 0.5%.

    Full Text Available The economic crisis so strongly affecting some southern European countries has led to significant cuts in the system of universal public health care in Spain. Such measures particularly affect irregular immigrants and can also cause significant public health consequences. A form of civil resistance that deserves to be analyzed is the conscientious objection of Spanish doctors who have chosen to continue attending irregular immigrants in contravention of new the rules restricting their access to the public health system and their right to health. The aim of this paper is to analyze the new regulation which cut health care for irregular immigrants in Spain, the impact of this new regulation on the most vulnerable groups, and the response of doctors, who exercised their right to conscientious objection in relation to applying the new regulation. Finally to examine the announcement of change which came about as a consequence of international and domestic social pressure causing political risk to the Spanish National Government.

    2015-06-01

    This article focuses on Tasmania's Reproductive Health (Access to Terminations) Act 2013, which decriminalises abortion in that State. The article first provides an overview of the Tasmanian legislation, comparing it with Victoria's Abortion Law Reform Act 2008. It then provides a more in-depth analysis of a doctor's right to "conscientious objection" and the requirement in both Acts of an "obligation to refer". The article concludes that ultimately, as a democratic society, it is important that both a woman's right to terminate a pregnancy and a doctor's right to freedom of conscience is respected. Where these rights conflict, as is the case when a doctor with a conscientious objection to abortion is confronted with a patient who seeks information about abortion, they must be balanced. The Victorian and Tasmanian Acts represent a considered and reasonable approach to balancing the rights at issue.

    2008-03-01

    We examined relations between the Five-factor model (FFM) domains and facets of Agreeableness and Conscientiousness, hypothesized behavioral manifestations of these traits (e.g., social information processing and delay discounting), and externalizing behaviors in an undergraduate sample. Agreeableness and Conscientiousness were differentially related to the externalizing behaviors and the laboratory tasks, which in turn evinced significant relations with externalizing behaviors. The personality facets displayed evidence of modest incremental validity over the broader domains and were related to the externalizing behaviors even when controlling for the social information processing and behavioral discounting variables. In general, the results support the validity of the FFM domains and facets, particularly Agreeableness, in the prediction of a variety of externalizing behaviors.

  13. The ‘Dark Side’ and ‘Bright Side’ of Personality: When Too Much Conscientiousness and Too Little Anxiety Are Detrimental with Respect to the Acquisition of Medical Knowledge and Skill

    Theory suggests that personality traits evolved to have costs and benefits, with the effectiveness of a trait dependent on how these costs and benefits relate to the present circumstances. This suggests that traits that are generally viewed as positive can have a ‘dark side’ and those generally viewed as negative can have a ‘bright side’ depending on changes in context. We test this in a sample of 220 UK medical students with respect to associations between the Big 5 personality traits and learning outcomes across the 5 years of a medical degree. The medical degree offers a changing learning context from pre-clinical years (where a more methodical approach to learning is needed) to the clinical years (where more flexible learning is needed, in a more stressful context). We argue that while trait conscientiousness should enhance pre-clinical learning, it has a ‘dark side’ reducing the acquisition of knowledge in the clinical years. We also suggest that anxiety has a ‘bright side’ enhancing the acquisition of skills in the clinical years. We also explore if intelligence enhances learning across the medical degree. Using confirmatory factor analysis and structural equation modelling we show that medical skills and knowledge assessed in the pre-clinical and clinical years are psychometrically distinguishable, forming a learning ‘backbone’, whereby subsequent learning outcomes are predicted by previous ones. Consistent with our predictions conscientiousness enhanced preclinical knowledge acquisition but reduced the acquisition of clinical knowledge and anxiety enhanced the acquisition of clinical skills. We also identified a curvilinear U shaped association between Surgency (extraversion) and pre-clinical knowledge acquisition. Intelligence predicted initial clinical knowledge, and had a positive total indirect effect on clinical knowledge and clinical skill acquisition. For medical selection, this suggests that selecting students high on

    Zampas, Christina

    2013-12-01

    The practice of conscientious objection by healthcare workers is growing across the globe. It is most common in reproductive healthcare settings because of the religious or moral values placed on beliefs as to when life begins. It is often invoked in the context of abortion and contraceptive services, including the provision of information related to such services. Few states adequately regulate the practice, leading to denial of access to lawful reproductive healthcare services and violations of fundamental human rights. International ethical, health, and human rights standards have recently attempted to address these challenges by harmonizing the practice of conscientious objection with women's right to sexual and reproductive health services. FIGO ethical standards have had an important role in influencing human rights development in this area. They consider regulation of the unfettered use of conscientious objection essential to the realization of sexual and reproductive rights. Under international human rights law, states have a positive obligation to act in this regard. While ethical and human rights standards regarding this issue are growing, they do not yet exhaustively cover all the situations in which women's health and human rights are in jeopardy because of the practice. The present article sets forth existing ethical and human rights standards on the issue and illustrates the need for further development and clarity on balancing these rights and interests.

    In Brazil, to have a legal abortion in the case of rape, the woman's statement that rape has occurred is considered sufficient to guarantee the right to abortion. The aim of this study was to understand the practice and opinions about providing abortion in the case of rape among obstetricians-gynecologists (OBGYNs) in Brazil. A mixed-method study was conducted from April to July 2012 with 1,690 OBGYNs who responded to a structured, electronic, self-completed questionnaire. In the quantitative phase, 81.6% of the physicians required police reports or judicial authorization to guarantee the care requested. In-depth telephone interviews with 50 of these physicians showed that they frequently tested women's rape claim by making them repeat their story to several health professionals; 43.5% of these claimed conscientious objection when they were uncertain whether the woman was telling the truth. The moral environment of illegal abortion alters the purpose of listening to a patient - from providing care to passing judgement on her. The data suggest that women's access to legal abortion is being blocked by these barriers in spite of the law. We recommend that FEBRASGO and the Ministry of Health work together to clarify to physicians that a woman's statement that rape occurred should allow her to access a legal abortion.

    Reproductive health care is the only field in medicine where health care professionals (HCPs) are allowed to limit a patient's access to a legal medical treatment - usually abortion or contraception - by citing their 'freedom of conscience.' However, the authors' position is that 'conscientious objection' ('CO') in reproductive health care should be called dishonourable disobedience because it violates medical ethics and the right to lawful health care, and should therefore be disallowed. Three countries - Sweden, Finland, and Iceland - do not generally permit HCPs in the public health care system to refuse to perform a legal medical service for reasons of 'CO' when the service is part of their professional duties. The purpose of investigating the laws and experiences of these countries was to show that disallowing 'CO' is workable and beneficial. It facilitates good access to reproductive health services because it reduces barriers and delays. Other benefits include the prioritisation of evidence-based medicine, rational arguments, and democratic laws over faith-based refusals. Most notably, disallowing 'CO' protects women's basic human rights, avoiding both discrimination and harms to health. Finally, holding HCPs accountable for their professional obligations to patients does not result in negative impacts. Almost all HCPs and medical students in Sweden, Finland, and Iceland who object to abortion or contraception are able to find work in another field of medicine. The key to successfully disallowing 'CO' is a country's strong prior acceptance of women's civil rights, including their right to health care.

    As criticisms of factory farming continue to mount, an increasing number of individuals have changed their existing dietary practices. Perhaps the two most important options for those reacting against industrial farming are (1) vegetarianism/veganism (i.e., veg*nism), the avoidance of animal flesh/all animal products; and (2) conscientious omnivorism (CO), the consumption of meat or fish only when it satisfies certain ethical standards. While the former group has recently received much attention in the social science literature, studies specifically examining those who identify themselves as COs have been virtually nonexistent. The present research sought to investigate possible underlying attitudinal differences between the two groups. Results indicated that relative to veg*ns, COs evaluated animals less favorably, meat more favorably, and were lower in idealism, misanthropy, and ingroup identification. Mediation analysis demonstrated that differences between COs and veg*ns in the perceived acceptability of killing animals for food were mediated by beliefs about animals and meat. The discussion largely speculates on the causal direction of these effects.

    Intensive care unit (ICU) clinicians sometimes have a conscientious objection (CO) to providing or disclosing information about a legal, professionally accepted, and otherwise available medical service. There is little guidance about how to manage COs in ICUs. To provide clinicians, hospital administrators, and policymakers with recommendations for managing COs in the critical care setting. This policy statement was developed by a multidisciplinary expert committee using an iterative process with a diverse working group representing adult medicine, pediatrics, nursing, patient advocacy, bioethics, philosophy, and law. The policy recommendations are based on the dual goals of protecting patients' access to medical services and protecting the moral integrity of clinicians. Conceptually, accommodating COs should be considered a "shield" to protect individual clinicians' moral integrity rather than as a "sword" to impose clinicians' judgments on patients. The committee recommends that: (1) COs in ICUs be managed through institutional mechanisms, (2) institutions accommodate COs, provided doing so will not impede a patient's or surrogate's timely access to medical services or information or create excessive hardships for other clinicians or the institution, (3) a clinician's CO to providing potentially inappropriate or futile medical services should not be considered sufficient justification to forgo the treatment against the objections of the patient or surrogate, and (4) institutions promote open moral dialogue and foster a culture that respects diverse values in the critical care setting. This American Thoracic Society statement provides guidance for clinicians, hospital administrators, and policymakers to address clinicians' COs in the critical care setting.

    A high power microwave system based on power combining and pulse compression of conventional klystrons is introduced in this paper. This system mainly consists of pulse modulator, power combiner, driving source of klystrons and pulse compressor. A solid state induction modulator and pulse transformer were used to drive two 50 MW S-band klystrons with pulse widths 4 {\\mu}s in parallel, after power combining and pulse compression, the tested peak power had reached about 210 MW with pulse widths nearly 400 ns at 25 Hz, while the experimental maximum output power was just limited by the power capacity of loads. This type of high power microwave system has widely application prospect in RF system of large scale particle accelerators, high power radar transmitters and high level electromagnetic environment generators.

    Full Text Available Recent estimates suggest 60 % of the U.S. adult population uses the Internet to find health-related information. The goal of the present study was to model health-related Internet searches as a function of an interdependent system of personality adaptation in the context of recent health and aging-related concerns. Assessments of background factors, Big Five personality traits, past-month health and aging-related concerns, and the frequency of past-month health-related Internet searches (via Google, Yahoo, AOL, Bing, or some other search engine were obtained from a representative U.S. sample (N = 1,015. Controlling for background factors, regression analyses showed more frequent health-related Internet searches were predicted by a drive for exploration and investigation (high openness, as well as alarm sensitivity (high openness and high neuroticism and an anticipatory inclination (high openness and high conscientiousness in the context of recent problems with aging parents and recent health concerns for a family member. Consistent with interdependent models of personality adaptation, as well as prior evidence for surrogate health-related Internet searches, the results suggest a personality process model of search behavior that is partially dependent upon dispositional levels of exploration, emotional stability, control, and health and aging concerns for family members.

    The in vitro effects of levofloxacin and vancomycin in combination were evaluated against high level aminoglycoside-resistant (HLAR) enterococci using chequerboard and time-kill curve techniques. We examined 28 strains of enterococci comprising 17 Enterococcus faecalis, 10 E. faecium and one E. durans. The combination of vancomycin and levofloxacin had indifferent activity against all isolates according to chequerboard microdilution method, but was synergistic for two isolates, one E. faecium and one E. faecalis, using the time-kill curve method. Both strains were levofloxacin resistant and had high level aminoglycoside resistance to gentamicin and streptomycin. Antagonism was not detected in any strain. The results of this study suggested that the combination of vancomycin with levofloxacin does not often show synergistic effect against high level aminoglycoside-resistant enterococci.

    Single-photon detection with high efficiency, high time resolution, low dark counts and high photon detection-rates is required for a wide range of optical measurements. Although efficient detectors have been reported, combining all performances in a single device remains a challenge. Here, we show a broadband NbTiN superconducting nanowire detector with an efficiency over 92%, over 150MHz photon detection-rate and dark counts below 130Hz operated in a conventional Gifford-McMahon cryostat. Furthermore, with an optimized detector and readout electronics, we reach a record low jitter of 14.80ps while maintaining high efficiency.

    PROFESSIONAL INDEPENDENCE: The physician's conscientious duty is primarily implies that he/she provides the patient with personal and professionally non-dependent care, the consequences of which imply the physician's responsibility. INFORMATION FOR THE PATIENT: The physicians second duty is a major element of medical ethics: a physician must provide the patient with true, clear and appropriate information concerning the risks involved in the various investigations and treatments proposed. The physician must be able to prove that the patient has been well informed; such information can be provided by whatsoever means. The only dispensation from this is in emergency cases, or if the patient refuses to be informed. The fact that exposure to risk may be required medically, or only materializes exceptionally, does not justify limiting the information supplied. However, limited information may be necessary in the patient's interest, depending on the nature of the disease, its prognosis and the patient's character. NECESSITY AND DIFFICULTY IN INFORMING THE PATIENT: Before being an obligation, information is a necessity since it is required when, for example, obtaining the patient's informed consent. However, there is a great difference in the information supplied, and the correct interpretation of the message by the patient. There is also a risk of excess information, gendered by Internet and all the websites devoted to health, and the subsequent risk of mistrust. FEED-BACK: A new science, 'Cindynics', or the science of danger, based on past experience, proposes to use prior legal medical affairs in order to learn from the lessons they may provide, in the development of preventive measures. THE NOTION OF A HEALTH DUTY: Medicine attempts to restore good health when altered it can also ensure preventive measures. The obligation to apply such measures depends not only on the State but also on individuals, who, by avoiding situations at risk, ensure their health duty.

    Conscientious objection (CO) to participating in induced abortion is not present in the Finnish health care system or legislation unlike in many other European countries. We conducted a questionnaire survey with the 1(st)- and the last-year medical and nursing students and professionals (548 respondents; response rate 66-100%) including several aspects of the abortion process and their relation to CO in 2013. The male medical respondents chose later time points of pregnancy than the nursing respondents when considering when the embryo/fetus "becomes a person". Of all respondents, 3.5-14.1% expressed a personal wish to CO. The medical professionals supported the right to CO more often (34.2%) than the nursing professionals (21.4%), while ≥62.4% could work with someone expressing CO. Yet ≥57.9% of the respondents anticipated social problems at work communities caused by CO. Most respondents considered self-reported religious/ethical conviction to be adequate for CO but, at the same time, 30.1-50.7% considered that no conviction would be sufficient. The respondents most commonly included the medical doctor conducting surgical or medical abortion to be eligible to CO. The nursing respondents considered that vacuum suction would be a better justification for CO than medical abortion. The indications most commonly included to potential CO were second-trimester abortions and social reasons. Among the medical respondents, the men were more willing to grant CO also in case of a life-threatening emergency of the pregnant woman. While the respondents mostly seemed to consider the continuation of adequate services important if CO is introduced, the viewpoint was often focused on the staff and surgical abortion procedure instead of the patients. The issue proved to be complex, which should be taken into consideration for legislation.

    Personality traits are among the most complex quantitative traits. Certain personality traits have been postulated to be part of the inherited component of substance dependence (SD) risk. Association between the M2 cholinergic receptor gene (CHRM2) and SD has recently been reported and replicated (Wang et al. Hum. Mol. Genet. (2004);13:1903-1911; Luo et al. Hum. Mol. Genet. 2005;14:2421-2434). In this study, we investigated the relationship between CHRM2 variation and personality traits in two American populations. We assessed dimensions of the five-factor model of personality, and genotyped six CHRM2 markers and 38 unlinked ancestry-informative markers in 239 subjects with SD [173 European-Americans (EAs) and 66 African-Americans (AAs)] and 275 healthy subjects (237 EAs and 38 AAs). The relationships between CHRM2 markers and personality traits were examined using multivariate analysis of covariance, controlling for marker-marker interaction effects and potential confounders. Associations were decomposed by Roy Bargmann stepdown analysis of covariance. Generally, substance-dependent patients, older individuals, males, and AAs scored higher on Neuroticism and lower on other personality factors. Diplotype CTCAAA/CTCGTT (P = 0.005) and the interaction between its two haplotypes (CTCAAA x CTCGTT) (P = 0.003) were associated with lower Conscientiousness scores. Haplotype CTCGAT (P = 0.006) and its interaction with haplotype TCAAAT (P = 0.002) were associated with higher Agreeableness scores. The trait-influencing variant site in CHRM2 for Agreeableness was close to marker rs1824024 (SNP3) (P = 0.002). CHRM2 variation may contribute to the genetic component of variation in personality traits. Personality traits might substantially underlie the heritable component of SD.

  10. Influence of a falling edge on high power microwave pulse combination

    2016-07-01

    This paper presents an explanation of the influence of a microwave falling edge on high-power microwave pulse combination. Through particle-in-cell simulations, we discover that the falling edge is the driving factor that limits the output power of the combined pulses. We demonstrate that the space charge field, which accumulates to become comparable to the E-field at the falling edge of the former pulse, will trap the electrons in the gas layer and decrease its energy to attain a high ionization rate. Hence, avalanche discharge, caused by trapped electrons, makes the plasma density to approach the critical density and cuts off the latter microwave pulse. An X-band combination experiment is conducted with different pulse intervals. This experiment confirms that the high density plasma induced by the falling edge can cut off the latter pulse, and that the time required for plasma recombination in the transmission channel is several microseconds. To ensure a high output power for combined pulses, the latter pulse should be moved ahead of the falling edge of the former one, and consequently, a beat wave with high peak power becomes the output by adding two pulses with normal amplitudes.

    A novel Ka-band high efficiency asymmetric waveguide four-port combiner for coherent combining of two Monolithic Microwave Integrated Circuit (MMIC) Solid State Power Amplifiers (SSPAs) having unequal outputs has been successfully designed, fabricated and characterized over the NASA deep space frequency band from 31.8 to 32.3 GHz. The measured combiner efficiency is greater than 90 percent, the return loss greater than 18 dB and input port isolation greater than 22 dB. The manufactured combiner was designed for an input power ratio of 2:1 but can be custom designed for any arbitrary power ratio. Applications considered are NASA s space communications systems needing 6 to 10 W of radio frequency (RF) power. This Technical Memorandum (TM) is an expanded version of the article recently published in Institute of Engineering and Technology (IET) Electronics Letters.

Integrated combination of drugs that target tumor microenvironment is a promising approach to anticancer therapy. Here, we report a multifunctional combination of low-cytotoxic drugs composed of dipyridamole, bestatin and dexamethasone (DBDx which mainly acts on the tumor microenvironment shows highly potent antitumor efficacy in vivo. In mouse hepatoma H22 model, the triple drug combination showed synergistic and highly potent antitumor efficacy. The combination indices of various combinations of the triple drugs were between 0.2 and 0.5. DBDx inhibited the growth of a panel of human tumor xenografts and showed no obvious systemic toxicity. At tolerated doses, DBDx suppressed the growth of human hepatocellular carcinoma BEL-7402, HepG2, and lung adenocarcinoma A549 xenografts by 94.5%, 93.7% and 96.9%, respectively. Clonogenic assay demonstrated that DBDx showed weak cytotoxicity. Western blot showed that Flk1 and Nos3 were down-regulated in the DBDx-treated group. Proteomic analysis showed that DBDx mainly affected the metabolic process and immune system process; in addition, the angiogenesis and VEGF signaling pathway were also affected. Conclusively, DBDx, a multifunctional drug combination of three low-cytotoxic drugs, shows synergistic and highly potent antitumor efficacy evidently mediated by the modulation of tumor microenvironment. Based on its low-cytotoxic attributes and its broad-spectrum antitumor therapeutic efficacy, this multifunctional combination might be useful in the treatment of cancers, especially those refractory to conventional chemotherapeutics.

    A simplified design method has been proposed for systematic design of novel radio frequency (rf) power combiner and divider, incorporating radial slab-line structure, without using isolation resistor and external tuning mechanism. Due to low insertion loss, high power capability, and rigid mechanical configuration, this structure is advantageous for modern solid state rf power source used for feeding rf energy to superconducting accelerating structures. Analysis, based on equivalent circuit and radial transmission line approximation, provides simple design formula for calculating combiner parameters. Based on this method, novel 8-way and 16-way power combiners, with power handling capability of 4 kW, have been designed, as part of high power solid state rf amplifier development. Detailed experiments showed good performance in accordance with theory.

    NASA is planning a number of Space Exploration, Earth Observation and Space Science missions where Ka-band solid-state power amplifiers (SSPAs) could have a role. Monolithic microwave integrated circuit (MMIC) based SSPAs with output powers on the order of 10 W at Ka-band frequencies would be adequate to satisfy the data transmission rate requirements at the distances involved. MMICs are a type of integrated circuit fabricated on a GaAs wafer, which operates at micro wave frequencies and performs the function of signal amplification. The highest power Ka-band (31.8 to 32.3 GHz) SSPA to have flown in space had an output power of 2.6 W with an overall efficiency of 14.3 percent. This SSPA was built around discrete GaAs pHEMT (high electron mobility transistor) devices and flew aboard the Deep Space One spacecraft. State-of-the-art GaAs pHEMT-based MMIC power amplifiers (PAs) can deliver RF power at Ka-band frequencies anywhere from 3 W with a power added efficiency (PAE) of 32 percent to 6 W with a PAE of 26 percent. However, to achieve power levels higher than 6 W, the output of several MMIC PAs would need to be combined using a high-efficiency power combiner. Conventional binary waveguide power combiners, based on short-slot and magic-T circuits, require MMIC PAs with identical amplitude and phase characteristics for high combining efficiency. However, due to manufacturing process variations, the output powers of the MMIC PAs tend to be unequal, and hence the need to develop unequal power combiners. A two-way asymmetric magic-T based power combiner for MMIC power amplifiers, which can take in unequal inputs, has been successfully designed, fabricated, and characterized over NASA s Deep Space Network (DSN) frequency range of 31.8 to 32.3 GHz. The figure is a transparent view of the a sym - metric combiner that shows the 4-port configuration and the internal structure. The rod, post, and iris are positioned by design to achieve the desired asymmetric power ratio

    Personality traits such as conscientiousness as self-reported by individuals can help predict a range of outcomes, from job performance to longevity. Asking others to rate the personality of their acquaintances often provides even better predictive power than using self-report. Here, we examine whether peer-reported personality can provide a better link between brain function, namely threat-related amygdala activity, and future health-related behavior, namely problem drinking, than self-reported personality. Using data from a sample of 377 young adult university students who were rated on five personality traits by peers, we find that higher threat-related amygdala activity to fearful facial expressions is associated with higher peer-reported, but not self-reported, conscientiousness. Moreover, higher peer-reported, but not self-reported, conscientiousness predicts lower future problem drinking more than one year later, an effect specific to men. Remarkably, relatively higher amygdala activity has an indirect effect on future drinking behavior in men, linked by peer-reported conscientiousness to lower future problem drinking. Our results provide initial evidence that the perceived conscientiousness of an individual by their peers uniquely reflects variability in a core neural mechanism supporting threat responsiveness. These novel patterns further suggest that incorporating peer-reported measures of personality into individual differences research can reveal novel predictive pathways of risk and protection for problem behaviors.

    Conscientiousness is associated with longevity. As such, identifying the biological pathways linking personality to mortality is important. This study employs longitudinal data spanning >40 years to test prospective associations with Leukocyte Telomere Length (LTL), a potential marker of cellular aging. Because telomeres shorten over time, and are sensitive to oxidative stress, shorter LTL may reflect cumulative damage associated with negative health behaviors and past stressful events. We investigated childhood conscientiousness as a protective factor, expecting an association with longer LTL in adulthood, possibly reflecting slower LTL shortening. Potential lifespan pathways involving childhood trauma, smoking behaviors, and Body Mass Index (BMI) were explored. Childhood conscientiousness showed a small raw association with LTL (r = .08, p = .04), although this effect did not persist when controlling for age and sex. Despite this lack of a direct effect on LTL, we detected an indirect effect operating jointly through BMI and smoking. Higher rates of childhood betrayal trauma were associated with shorter LTL. Contrary to our hypothesis that conscientiousness would buffer this effect, we found evidence for an interaction with childhood betrayal traumas where the association between childhood betrayal traumas and LTL was larger for those higher on conscientiousness in childhood.

    The type of a nucleic acid and the type of the cell to be transfected generally affect the efficiency of electroporation, the versatile method of choice for gene regulation studies or for recombinant protein expression. We here present a combined square pulse electroporation strategy to reproducibly and efficiently transfect eukaryotic cells. Cells suspended in a universal buffer system received an initial high voltage pulse that was continuously combined with a subsequent low voltage pulse with independently defined electric parameters of the effective field and the duration of each pulse. At comparable viable cell recoveries and transfection efficiencies of up to 95% of all cells, a wide variety of cells especially profited from this combined pulse strategy by high protein expression levels of individual cells after transfection. Long-term silencing of gene expression by transfected small interfering RNA was most likely due to the uptake of large nucleic acid amounts as shown by direct detection of fluorochromated small interfering RNA.

    Thorsten Stroh

    Full Text Available The type of a nucleic acid and the type of the cell to be transfected generally affect the efficiency of electroporation, the versatile method of choice for gene regulation studies or for recombinant protein expression. We here present a combined square pulse electroporation strategy to reproducibly and efficiently transfect eukaryotic cells. Cells suspended in a universal buffer system received an initial high voltage pulse that was continuously combined with a subsequent low voltage pulse with independently defined electric parameters of the effective field and the duration of each pulse. At comparable viable cell recoveries and transfection efficiencies of up to 95% of all cells, a wide variety of cells especially profited from this combined pulse strategy by high protein expression levels of individual cells after transfection. Long-term silencing of gene expression by transfected small interfering RNA was most likely due to the uptake of large nucleic acid amounts as shown by direct detection of fluorochromated small interfering RNA. The highly efficient combined pulse electroporation strategy enables for external regulation of the number of naked nucleic acid molecules taken up and can be easily adapted for cells considered difficult to transfect.

    A 1.6-THz power-combined Schottky frequency tripler was designed to handle approximately 30 mW input power. The design of Schottky-based triplers at this frequency range is mainly constrained by the shrinkage of the waveguide dimensions with frequency and the minimum diode mesa sizes, which limits the maximum number of diodes that can be placed on the chip to no more than two. Hence, multiple-chip power-combined schemes become necessary to increase the power-handling capabilities of high-frequency multipliers. The design presented here overcomes difficulties by performing the power-combining directly on-chip. Four E-probes are located at a single input waveguide in order to equally pump four multiplying structures (featuring two diodes each). The produced output power is then recombined at the output using the same concept.

    A new kind of adaptive optics (AO) system, in which several low spatial frequency deformable mirrors(DMs) with optical conjugation relationship are combined to correct high-order aberrations, is proposed.The phase compensation principle and the control method of the combinational AO system are introduced.The numerical simulations for the AO system with two 60-element DMs are presented. The results indicate that the combinational DM in the AO system can correct different aberrations effectively as one single DM with more actuators, and there is no change of control method. This technique can be applied to a large telescope AO system to improve the spatial compensation capability for wavefront by using current DM.

    Recent advances in optical tweezers have greatly expanded their measurement capabilities. A new generation of hybrid instrument that combines nanomechanical manipulation with fluorescence detection-fluorescence optical tweezers, or "fleezers"-is providing a powerful approach to study complex macromolecular dynamics. Here, we describe a combined high-resolution optical trap/confocal fluorescence microscope that can simultaneously detect sub-nanometer displacements, sub-piconewton forces, and single-molecule fluorescence signals. The primary technical challenge to these hybrid instruments is how to combine both measurement modalities without sacrificing the sensitivity of either one. We present general design principles to overcome this challenge and provide detailed, step-by-step instructions to implement them in the construction and alignment of the instrument. Lastly, we present a set of protocols to perform a simple, proof-of-principle experiment that highlights the instrument capabilities.

    N-and C-domains of human immunodeficiency virus type 1 (HIV-1) gp41 are demonstrated to play an important role in HIV-entry and prevention. In addition, the V3 loop on gp120 was identified as the principal neutralizing determinant (PND). Based on the fact that a combination of several monoclonal antibodies to different neutralizing epitopes showed great protection against intravenous challenge and vaginal transmission of pathogenic HIV-1/Simian immunodeficiency virus (SIV) chimeric virus on macaques, three candidate peptide-vaccines were prepared and used in combination to induce high levels of multiantibodies against HIV-1. The three peptides contained important functional regions on HIV-1 gp160. The N-domain peptide (P1: aa550-579) and C-domain peptide (P2: aa633-662) of gp41 and V3 peptide (P3: aa301-328) of gp120 were conjugated with bovine serum albumin (BSA) using the glutaraldehyde method. After the vaccination course, each of the three candidate peptide-vaccines induced strong antibody response in rabbits. The three vaccines used in combination induced high levels of multiantibodies against the peptides of the N-and C-domains and the V3 Ioop, with the titer of antibodies up to 1: 6400-1: 25 600 in rabbit sera in comparison with the titer of 1: 800-1:3200 induced by rgp41 or rgp160. Our results indicate that immunogenicities of the N-and C-domains and the V3 loop in these three candidate peptide-vaccines were clearly stronger than those induced by rgp41 or rgp160, and these peptide-vaccines used in combination synchronously induced high levels of multiantibodies against HIV-1, suggesting that used in combination they may provide a new vaccine-strategy to induce strong multi-antiviral activity.

    To date, much effort has been expended on making high-performance microscopes through better instrumentation. Recently, it was discovered that physical magnification of specimens was possible, through a technique called expansion microscopy (ExM), raising the question of whether physical magnification, coupled to inexpensive optics, could together match the performance of high-end optical equipment, at a tiny fraction of the price. Here we show that such “hybrid microscopy” methods—combining physical and optical magnifications—can indeed achieve high performance at low cost. By physically magnifying objects, then imaging them on cheap miniature fluorescence microscopes (“mini-microscopes”), it is possible to image at a resolution comparable to that previously attainable only with benchtop microscopes that present costs orders of magnitude higher. We believe that this unprecedented hybrid technology that combines expansion microscopy, based on physical magnification, and mini-microscopy, relying on conventional optics—a process we refer to as Expansion Mini-Microscopy (ExMM)—is a highly promising alternative method for performing cost-effective, high-resolution imaging of biological samples. With further advancement of the technology, we believe that ExMM will find widespread applications for high-resolution imaging particularly in research and healthcare scenarios in undeveloped countries or remote places.

    Produced at Fuji Electric Co.,Ltd., on a commercial basis was a high resolution absolute incremental combined-use encoder, which is a serial transmission type with a resolution of 16bit per rotation, as a rotary sensor for a small high performance servo system FALDIC-{alpha} series. Accomplished in this encoder were a high resolution, which greatly improves uneven rotation at low speed and precision in positioning, and miniaturization which is on the top level in the industry, by means of a high performance CPU and a large scale LSI. In addition, less wiring by unique high-speed serial communication was contrived, as were protective functions of all types and intelligent systematization by data holding function. Moreover, a newly structured rotary disk was employed, greatly improving vibration resistance and impact resistance. By using the high resolution absolute incremental combined-use encoder as standard equipment in the servo motor, flexibility is secured in a system for a machine to which the device is applied.

    2012-11-20

    Microdroplets offer unique compartments for accommodating a large number of chemical and biological reactions in tiny volume with precise control. A major concern in droplet-based microfluidics is the difficulty to address droplets individually and achieve high throughput at the same time. Here, we have combined an improved cartridge sampling technique with a microfluidic chip to perform droplet screenings and aggressive reaction with minimal (nanoliter-scale) reagent consumption. The droplet composition, distance, volume (nanoliter to subnanoliter scale), number, and sequence could be precisely and digitally programmed through the improved sampling technique, while sample evaporation and cross-contamination are effectively eliminated. Our combined device provides a simple model to utilize multiple droplets for various reactions with low reagent consumption and high throughput. © 2012 American Chemical Society.

    2008-01-01

    A new Digital Elevation Model was created using the best available high-resolution topography and multibeam bathymetry surrounding the area of Seward, Alaska. Datasets of (1) LIDAR topography collected for the Kenai Watershed Forum, (2) Seward harbor soundings from the U.S. Army Corp of Engineers, and (3) multibeam bathymetry from the National Oceanic and Atmospheric Administration contributed to the final combined product. These datasets were placed into a common coordinate system, horizontal datum, vertical datum, and data format prior to being combined. The projected coordinate system of Universal Transverse Mercator Zone 6 North American Datum of 1927 was used for the horizontal coordinates. Z-values in meters were referenced to the tidal datum of Mean High Water. Gaps between the datasets were interpolated to create the final seamless 5-meter grid covering the area of interest around Seward, Alaska.

    The current driven by combined electron cyclotron wave (ECW) and high harmonic fast wave is investigated using the GENRAY/CQL3D package. It is shown that no significant synergetic current is found in a range of cases with a combined ECW and fast wave (FW). This result is consistent with a previous study [Harvey et al., in Proceedings of IAEA TCM on Fast Wave Current Drive in Reactor Scale Tokamaks (Synergy and Complimentarily with LHCD and ECRH), Arles, France, IAEA, Vienna, 1991]. However, a positive synergy effect does appear with the FW in the lower hybrid range of frequencies. This positive synergy effect can be explained using a picture of the electron distribution function induced by the ECW and a very high harmonic fast wave (helicon). The dependence of the synergy effect on the radial position of the power deposition, the wave power, the wave frequency, and the parallel refractive index is also analyzed, both numerically and physically.

    The current treatment for vascular malformations includes surgery, sclerotherapy, and embolization. However, each method has its limitations, such as recurrence, complications, scarring, and radiation exposure. Therefore, identifying an effective, minimally invasive treatment that reduces lesion recurrence is particularly important. We describe in detail a patient who received treatment with ultrasound-guided laser interruption of feeding vessels combined with polidocanol sclerotherapy after the recurrence of forearm high-flow vascular malformation.

    2015-01-01

    Aims: In this work, we discuss a way to combine High Dispersion Spectroscopy and High Contrast Imaging (HDS+HCI). For a planet located at a resolvable angular distance from its host star, the starlight can be reduced up to several orders of magnitude using adaptive optics and/or coronography. In addition, the remaining starlight can be filtered out using high-dispersion spectroscopy, utilizing the significantly different (or Doppler shifted) high-dispersion spectra of the planet and star. In this way, HDS+HCI can in principle reach contrast limits of ~1e-5 x 1e-5, although in practice this will be limited by photon noise and/or sky-background. Methods: We present simulations of HDS+HCI observations with the E-ELT, both probing thermal emission from a planet at infrared wavelengths, and starlight reflected off a planet atmosphere at optical wavelengths. For the infrared simulations we use the baseline parameters of the E-ELT and METIS instrument, with the latter combining extreme adaptive optics with an R=100,...

  17. Do motives matter in male circumcision? 'Conscientious objection' against the circumcision of a Muslim child with a blood disorder.

    2014-02-01

    Whilst there have been serious attempts to locate the practice of male circumcision for religious motives in the context of the (respective) religion's narrative and community, the debate, when referring to a clinical context, is often more nuanced. This article will contribute further to the debate by contextualising the Islamic practice of male circumcision within the clinical setting typical of a contemporary hospital. It specifically develops an additional complication; namely, the child has a pre-existing blood disorder. As an approach to contributing to the circumcision debate further, the ethics of a conscientious objection for secular motives towards a religiously-motivated clinical intervention will be explored. Overall, the discussion will provide relevance for such debates within the value-systems of a multi-cultural society. This article replicates several approaches to deconstructing a request for conscientious refusal of non-therapeutic circumcision by a Clinical Ethics Committee (CEC), bringing to light certain contradictions that occur in normatively categorizing motives for performing the circumcision.

    Individual differences in cognitive efficiency, particularly in relation to working memory (WM), have been associated both with personality dimensions that reflect enduring regularities in brain configuration, and with short-term neural plasticity, that reflects task-related changes in brain connectivity. To elucidate the relationship of these two divergent mechanisms, we tested the hypothesis that personality dimensions, which reflect enduring aspects of brain configuration, inform about the neurobiological framework within which short-term, task-related plasticity, as measured by effective connectivity, can be facilitated or constrained. As WM consistently engages the dorsolateral prefrontal (DLPFC), parietal (PAR), and anterior cingulate cortex (ACC), we specified a WM network model with bidirectional, ipsilateral, and contralateral connections between these regions from a functional magnetic resonance imaging dataset obtained from 40 healthy adults while performing the 3-back WM task. Task-related effective connectivity changes within this network were estimated using Dynamic Causal Modelling. Personality was evaluated along the major dimensions of Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness. Only two dimensions were relevant to task-dependent effective connectivity. Neuroticism and Conscientiousness respectively constrained and facilitated neuroplastic responses within the WM network. These results suggest individual differences in cognitive efficiency arise from the interplay between enduring and short-term plasticity in brain configuration.

    In this study, a high-gravity rotating packed bed (HGRPB) was used as a catalytic ozonation reactor to decompose dimethyl phthalate (DMP), an endocrine disrupting chemical commonly encountered. The HGRPB is an effective gas-liquid mixing equipment which can enhance the ozone mass transfer coefficient. Platinum-containing catalyst (Pt/-Al2O3) of Dash 220N and ultra violet (UV) lamp were combined in the high-gravity ozonation (HG-OZ) system to enhance the self-decomposition of molecular ozone in liquid to form highly reactive radical species. Different combinations of HG-OZ with Dash 220N and UV for the degradation of DMP were tested. These include HG-OZ, HG catalytic OZ (HG-Pt-OZ), HG photolysis OZ (HG-UV-OZ) and HG-UV-Pt-OZ. The result indicated that all the above four ozonation processes result in significant decomposition of DMP and mineralization of total organic carbon (TOC) at the applied ozone dosage per volume of liquid sample of 1.2gL(-1). The UV and Pt/gamma-Al2O3 combined in HG-OZ can enhance the TOC mineralization efficiency (eta(TOC)) to 56% (via HG-UV-OZ) and 57% (via HG-Pt-OZ), respectively, while only 45% with ozone only. The process of HG-UV-Pt-OZ offers the highest eta(TOC) of about 68%.

    Background The number of highly sensitized patients is rising, and sensitization can lead to renal transplant failure.The present study aimed to investigate the safety and efficacy of protein A immunoadsorption combined with rituximab (RTX) in highly sensitized recipients of kidney transplants.Methods Seven highly sensitized recipients of living-related renal transplants (4 men and 3 women, mean aged 42.5 years old (range 33-51)) were pretreated with this combination. Human leukocyte antigen (HLA) mismatch number was 2-5. Panel reactive antibody (PRA) of class 1 was high in 2 cases and that of class Ⅱ was high in 1 case. All patients were pretreated with immunoadsorption 2-10 times. Immunoglobulin and PRA changes were monitored before and after absorption. The operation was conducted when PRA or immunoglobulin levels were at or below normal levels.Immunosuppressive drugs were provided 3-5 days before the operation, and one dose of RTX (375 mg/m~2) was infused with polyclonal antibody on the day of operation. Postoperative creatinine (Cr), creatinine clearance rate (Ccr), PRA ratio,and immunoglobulin changes were monitored.Results All 7 patients had good recovery without delayed graft function. Acute rejection occurred in 3 cases at postoperative days 8, 10, and 14, respectively. The Banff 07 biopsy grades were la in 1 case and lla C4d0 in 2 cases.Successful reversion was achieved after giving methylprednisolone or antithymocyte immunoglobulin + cyclophosphamide. All patients were discharged with normal renal function, mean class 1 PRA was 14% and mean class Ⅱ PRA was 35%. PRA was completely negative in 3 cases.Conclusion Protein A immunoadsorption combined with RTX can safely reduce the occurrence of humoral rejection in highly sensitized renal transplant recipients.

    2005-04-01

    Full Text Available Abstract Background Protein-protein interaction data used in the creation or prediction of molecular networks is usually obtained from large scale or high-throughput experiments. This experimental data is liable to contain a large number of spurious interactions. Hence, there is a need to validate the interactions and filter out the incorrect data before using them in prediction studies. Results In this study, we use a combination of 3 genomic features – structurally known interacting Pfam domains, Gene Ontology annotations and sequence homology – as a means to assign reliability to the protein-protein interactions in Saccharomyces cerevisiae determined by high-throughput experiments. Using Bayesian network approaches, we show that protein-protein interactions from high-throughput data supported by one or more genomic features have a higher likelihood ratio and hence are more likely to be real interactions. Our method has a high sensitivity (90% and good specificity (63%. We show that 56% of the interactions from high-throughput experiments in Saccharomyces cerevisiae have high reliability. We use the method to estimate the number of true interactions in the high-throughput protein-protein interaction data sets in Caenorhabditis elegans, Drosophila melanogaster and Homo sapiens to be 27%, 18% and 68% respectively. Our results are available for searching and downloading at http://helix.protein.osaka-u.ac.jp/htp/. Conclusion A combination of genomic features that include sequence, structure and annotation information is a good predictor of true interactions in large and noisy high-throughput data sets. The method has a very high sensitivity and good specificity and can be used to assign a likelihood ratio, corresponding to the reliability, to each interaction.

    2010-06-01

    Full Text Available Abstract Background DNA methylation changes are widely used as early molecular markers in cancer detection. Sensitive detection and classification of rare methylation changes in DNA extracted from circulating body fluids or complex tissue samples is crucial for the understanding of tumor etiology, clinical diagnosis and treatment. In this paper, we describe a combined method to monitor the presence of methylated tumor DNA in an excess of unmethylated background DNA of non-tumorous cells. The method combines heavy methyl-PCR, which favors preferential amplification of methylated marker sequence from bisulfite-treated DNA with a methylation-specific single nucleotide primer extension monitored by ion-pair, reversed-phase, high-performance liquid chromatography separation. Results This combined method allows detection of 14 pg (that is, four to five genomic copies of methylated chromosomal DNA in a 2000-fold excess (that is, 50 ng of unmethylated chromosomal background, with an analytical sensitivity of > 90%. We outline a detailed protocol for the combined assay on two examples of known cancer markers (SEPT9 and TMEFF2 and discuss general aspects of assay design and data interpretation. Finally, we provide an application example for rapid testing on tumor methylation in plasma DNA derived from a small cohort of patients with colorectal cancer. Conclusion The method allows unambiguous detection of rare DNA methylation, for example in body fluid or DNA isolates from cells or tissues, with very high sensitivity and accuracy. The application combines standard technologies and can easily be adapted to any target region of interest. It does not require costly reagents and can be used for routine screening of many samples.

    Full Text Available Combined liver kidney transplantation (CLKT has been used on many occasions and proved to be a successful event for both liver and kidney in highly sensitized patients. Our aim was to review the immunological and other laboratory results of a CLKT in a highly sensitized patient. CLKT was used to treat a highly sensitized, 42-year-old female. She was suffering from end-stage liver disease due to hepatitis C virus (HCV infection and renal disease due to diabetic nephropathy. Cross-matching, panel reactive assay (PRA and routine laboratory tests for liver and renal function were carried out before and after the CLKT. Prior to the CLKT, the patient was highly sensitized with human leukocytes antigens (anti-HLA class I antibodies (>90%. Patient was offered CLKT from a deceased donor. She had donor-specific antibodies, class I and II. Both T and B CDC cross-matches (XM were positive pre-transplant and eight hours post-transplant. Both cross-match and PRA results became completely negative six days post CKLT. Almost 30 months post CLKT, her renal function is normal and negative for class I and II PRA. Liver graft appears to be protective for renal graft when they are combined even in highly sensitized patients. CLKT is very useful in overcoming sensitization in addition to treating end-stage liver and renal diseases.

    Stability of vertical upright position of an inverted pendulum with its suspension point subjected to high frequency harmonics and stochastic excitations is investigated. Two classes of excitations, i.e., combined high frequency harmonic excitation and Gaussian white noise excitation, and high frequency bounded noise excitation, respectively,are considered. Firstly, the terms of high frequency harmonic excitations in the equation of motion of the system can be set equivalent to nonlinear stiffness terms by using the method of direct separation of motions. Then the stochastic averaging method of energy envelope is used to derive the averaged It(o) stochastic differential equation for system energy. Finally, the stability with probability 1 of the system is studied by using the largest Lyapunov exponent obtained from the averaged It(o) stochastic differential equation. The effects of system parameters on the stability of the system are discussed, and some examples are given to illustrate the efficiency of the proposed procedure.

    Full Text Available Our aim was to improve the prediction of unfavorable histopathology (UH in neuroblastic tumors through combined imaging and biochemical parameters.123I-MIBG SPECT and MRI was performed before surgical resection or biopsy in 47 consecutive pediatric patients with neuroblastic tumor. Semi-quantitative tumor-to-liver count-rate ratio (TLCRR, MRI tumor size and margins, urine catecholamine and NSE blood levels of neuron specific enolase (NSE were recorded. Accuracy of single and combined variables for prediction of UH was tested by ROC analysis with Bonferroni correction.34 of 47 patients had UH based on the International Neuroblastoma Pathology Classification (INPC. TLCRR and serum NSE both predicted UH with moderate accuracy. Optimal cut-off for TLCRR was 2.0, resulting in 68% sensitivity and 100% specificity (AUC-ROC 0.86, p < 0.001. Optimal cut-off for NSE was 25.8 ng/ml, resulting in 74% sensitivity and 85% specificity (AUC-ROC 0.81, p = 0.001. Combination of TLCRR/NSE criteria reduced false negative findings from 11/9 to only five, with improved sensitivity and specificity of 85% (AUC-ROC 0.85, p < 0.001.Strong 123I-MIBG uptake and high serum level of NSE were each predictive of UH. Combined analysis of both parameters improved the prediction of UH in patients with neuroblastic tumor. MRI parameters and urine catecholamine levels did not predict UH.

    The design and construction of a high-pressure (200 bar) and high-temperature (600 degrees C) heat-flow differential scanning calorimeter (DSC) for the in situ investigation of the hydrogenation and dehydrogenation reactions of hydrides is presented. In combination with a pressure-concentration-temperature (pcT) system, simultaneous thermodynamic and volumetric measurements become accessible. Due to the high thermal conductivity of hydrogen, only the sample cell and the reference cell are exposed to hydrogen and the remaining system is under ambient conditions. This separation has the advantage that the calibration factor is independent of the hydrogen pressure. The internal empty volume of the combined system is as low as possible to maximize the precision of the pcT measurements. The calorimetric block of the DSC is designed with a silver/copper alloy and the temperature measurements are made resistively with platinum temperature sensors (Pt 100). The instrument was calibrated and its operability was successfully studied on the example of the hydrogen sorption behavior of LaNi(5).

    A combination of microneedle pretreatment and iontophoresis was evaluated for the potential to increase skin permeation of drugs. Two model compounds with low and high molecular D(2)O and fluorescein isothiocyanate (FITC)-dextrans (FD-4, FD-10, FD-40, FD-70 and FD-2000; average molecular weight of 3.8, 10.1, 39.0, 71.2 and 200.0 kDa), respectively, were used and the effect of microneedle pretreatment and iontophoresis on their in vitro permeability was evaluated using excised hairless rat skin with a 2-chamber diffusion cell. Convective solvent flow through the skin was measured using a set of calibrated capillaries attached to the diffusion cell. The following results were obtained: (1) convective solvent flow (electroosmosis) during iontophoresis through microneedle-pretreated skin, 2.62+/-0.32 microL/cm(2)/h, was almost the same as through intact skin, 2.71+/-0.25 microL/cm(2)/h, and (2) the combination of microneedle pretreatment and subsequent iontophoresis significantly enhanced FD flux compared with microneedle pretreatment alone or iontophoresis alone, whereas no synergistic effect was found on the flux of D(2)O. These results suggest that the combination of iontophoresis with microneedle pretreatment may be a useful means to increase skin permeation of high molecular compounds.

    In this article, some information about the data used in the article and a citation were not included. The details of the corrections are provided.] This study uses 3-level, 2-wave time-lagged data from a random sample of 55 high-technology firms, 238 teams, and 1,059 individuals in China to investigate a multilevel combinational model of employee creativity. First, we hypothesize that firm (macrolevel) high-commitment work systems are conducive to individual (microlevel) creativity. Furthermore, we hypothesize that this positive crosslevel main impact may be combined with middle-level (mesolevel) factors, including team cohesion and team task complexity, such that the positive impact of firm high-commitment work systems on individual creativity is stronger when team cohesion is high and the team task more complex. The findings from random coefficient modeling analyses provide support for our hypotheses. These sets of results offer novel insight into how firms can use macrolevel and mesolevel contextual variables in a systematic manner to promote employee creativity in the workplace, despite its complex nature.

    In 2004, a combined system test was performed in the H8 beam line at the CERN SPS with a setup using muon chambers made of Monitored Drift Tubes (MDT) to form a spectrometer which represented 1% of the ATLAS detector. The basic design performances of the muon spectrometer were veried. The full ATLAS analysis chain was used to obtain the results presented in this paper. The stability of MDT calibration constants, the alignment system using optical devices and high energy tracks, as well as the intrinsic sagitta resolution of the Muon Spectrometer were studied and found to agree with expectations. The reconstruction of muon tracks using the combined information from both the Inner Detector and the Muon Spectrometer are also presented.

    The construction of three-dimensional graphene aerogels (GAs) is of great importance owing to their outstanding properties for various applications. Up to now, the combination of ultralow weight and super mechanical strength for GA remains a great challenge. Here we demonstrate the fabrication of cellular GAs by a facile, easily controlled and versatile route, i.e. the chemical reduction of graphene oxide assemblies at oil-water interface under a mild condition (70 °C). The GA is ultralight (with density <3 mg cm(-3)) yet mechanically resilient because the walls of the cell closely pack in a highly ordered manner to maximize mechanical strength. The GA has been utilized as an appealing reactor for catalytic hydrogenation, which exhibited great advantages such as large oil absorption capability, exceptional catalytic activity, ease of product separation and high stability.

    In this paper, an integral design that combines optical system with image processing is introduced to obtain high resolution images, and the performance is evaluated and demonstrated. Traditional imaging methods often separate the two technical procedures of optical system design and imaging processing, resulting in the failures in efficient cooperation between the optical and digital elements. Therefore, an innovative approach is presented to combine the merit function during optical design together with the constraint conditions of image processing algorithms. Specifically, an optical imaging system with low resolution is designed to collect the image signals which are indispensable for imaging processing, while the ultimate goal is to obtain high resolution images from the final system. In order to optimize the global performance, the optimization function of ZEMAX software is utilized and the number of optimization cycles is controlled. Then Wiener filter algorithm is adopted to process the image simulation and mean squared error (MSE) is taken as evaluation criterion. The results show that, although the optical figures of merit for the optical imaging systems is not the best, it can provide image signals that are more suitable for image processing. In conclusion. The integral design of optical system and image processing can search out the overall optimal solution which is missed by the traditional design methods. Especially, when designing some complex optical system, this integral design strategy has obvious advantages to simplify structure and reduce cost, as well as to gain high resolution images simultaneously, which has a promising perspective of industrial application.

    Full Text Available We describe the utilization of indocyanine green (ICG dye to facilitate combined/en bloc removal of epiretinal membranes (ERM along with internal limiting membranes (ILM. The method utilizes a highly diluted preparation of ICG in dextrose water solvent (D5W. Elimination of fluid air exchange step facilitating staining in the fluid phase and low intensity lighting help minimize potential ICG toxicity. The technique demonstrates how ICG facilitates negative staining of ERMs and how ILM peeling concomitantly can allow complete and efficient ERM removal minimizing surgical time and the necessity for dual or sequential staining.

    Both radiation and increased iron stores can independently increase oxidative damage, resulting in protein, lipid and DNA oxidation. Oxidative stress increases the risk of many health problems including cancer, cataracts, and heart disease. This study, a subset of a larger interdisciplinary investigation of the combined effect of iron overload on sensitivity to radiation injury, monitored immune parameters in the peripheral blood of rats subjected to gamma radiation, high dietary iron or both. Specific immune measures consisted of: (1) peripheral leukocyte distribution, (2) plasma cytokine levels and (3) cytokine production profiles following whole blood mitogenic stimulation

    2016-06-01

    A high rocky slope is an open complex giant system for which there is contradiction among different influencing factors and coexistence of qualitative and quantitative information. This study presents a comprehensive intelligent evaluation method of high rocky slope safety through an integrated analytic hierarchy process, extension matter element model and entropy weight to assess the safety behavior of the high rocky slope. The proposed intelligent evaluation integrates subjective judgments derived from the analytic hierarchy process with the extension matter model and entropy weight into a multiple indexes dynamic safety evaluation approach. A combined subjective and objective comprehensive evaluation process, a more objective study, through avoiding subjective effects on the weights, and a qualitative safety assessment and quantitative safety amount are presented in the proposed method. The detailed computational procedures were also provided to illustrate the integration process of the above methods. Safety analysis of one high rocky slope is conducted to illustrate that this approach can adequately handle the inherent imprecision and contradiction of the human decision-making process and provide the flexibility and robustness needed for the decision maker to better monitor the safety status of a high rocky slope. This study was the first application of the proposed integrated evaluation method in the safety assessment of a high rocky slope. The study also indicated that it can also be applied to other similar problems.

    It is the purpose of this study to examine the impact of "highly efficient" Design-of-Experiments (DOE) methods for combining sets of CFD generated analysis data with smaller sets of Experimental test data in order to accurately predict performance results where experimental test data were not obtained. The study examines the impact of micro-ramp flow control on the shock wave boundary layer (SWBL) interaction where a complete paired set of data exist from both CFD analysis and Experimental measurements By combining the complete set of CFD analysis data composed of fifteen (15) cases with a smaller subset of experimental test data containing four/five (4/5) cases, compound data sets (CFD/EXP) were generated which allows the prediction of the complete set of Experimental results No statistical difference were found to exist between the combined (CFD/EXP) generated data sets and the complete Experimental data set composed of fifteen (15) cases. The same optimal micro-ramp configuration was obtained using the (CFD/EXP) generated data as obtained with the complete set of Experimental data, and the DOE response surfaces generated by the two data sets were also not statistically different.

    The effects of noise and vibration on annoyance in buildings during the passage of a nearby high-speed train have been investigated in a laboratory experiment with recorded train noise and 20 Hz vibration. The noises included the effects of two types of façade: windows-open and windows-closed. Subjects were exposed to six levels of noise and six magnitudes of vibration, and asked to rate annoyance using an 11-point numerical scale. The experiment consisted of four sessions: (1) evaluation of noise annoyance in the absence of vibration, (2) evaluation of total annoyance from simultaneous noise and vibration, (3) evaluation of noise annoyance in the presence of vibration, and (4) evaluation of vibration annoyance in the absence of noise. The results show that vibration did not influence ratings of noise annoyance, but that total annoyance caused by combined noise and vibration was considerably greater than the annoyance caused by noise alone. The noise annoyance and the total annoyance caused by combined noise and vibration were associated with subject self-ratings of noise sensitivity. Two classical models of total annoyance due to combined noise sources (maximum of the single source annoyance or the integration of individual annoyance ratings) provided useful predictions of the total annoyance caused by simultaneous noise and vibration.

    2008-07-01

    Relationships between conscientiousness-related traits and transtheoretical model (TTM) of change constructs, exercise self-efficacy, and exercise behavior were examined in college and community samples (N=566). Measures of the conscientiousness-related traits of conventionality and industriousness were expected to show positive relations with measures of exercise behavior stage location, processes of exercise behavior change, endorsing the benefits of exercise behavior (i.e., decisional balance), exercise self-efficacy, and self-reported exercise behavior. In addition, based on Neo-Socioanalytic Theory (Roberts & Wood, 2006) an intervening role was predicted for TTM constructs and exercise self-efficacy in the relationship between conscientiousness-related traits and exercise behavior stage location. The results showed industriousness (being hardworking) to be the most robust conscientiousness-related predictor of stage location, processes of change, endorsing the benefits of exercise behavior, and exercise self-efficacy. Mediation analyses showed the relationship between industriousness and exercise behavior stage location to be fully accounted for by select processes of change and exercise self-efficacy scales. The results are discussed in terms of a useful integration of trait and social-cognitive approaches to exercise behavior, with an emphasis on the role of industriousness as an important individual difference factor therein.

    NASA is presently developing nuclear reactor technologies, under Project Prometheus, which will provide spacecraft with greatly increased levels of sustained onboard power and thereby dramatically enhance the capability for future deep space exploration. The first mission planned for use of this high power technology is the Jupiter Icy Moons Orbiter (JIMO). In addition to electric propulsion and science, there will also be unprecedented onboard power available for deep space communications. A 32 GHz transmitter with 1 kW of RF output power is being considered to enable the required very high data transmission rates. One approach to achieving the 1 kW RF power, now being investigated at NASA GRC, is the possible power combining of a number of 100-1 50 W TWTs now under development. The work presented here is the results of a proof-of-concept demonstration of the power combining Ka-band waveguide circuit design and test procedure using two Ka- band TWTAs (Varian model VZA6902V3 and Logimetrics model A440/KA-1066), both of which were previously employed in data uplink evaluation terminals at 29.36 GHz for the NASA Advanced Communications Technology Satellite (ACTS) program. The characterization of the individual TWTAs and power combining demonstration were done over a 500 MHz bandwidth from 29.1 to 29.6 GHz to simulate the Deep Space Network (DSN) bandwidth of 3 1.8 to 32.3 GHz. Figures 1-3 show some of the power transfer and gain measurements of the TWTAs using a swept signal generator (Agilent 83640b) for the RF input. The input and output powers were corrected for circuit insertion losses due to the waveguide components. The RF saturated powers of both ACTS TWTAs were on the order of 120 W, which is comparable to the expected output powers of the 32 GHz TWTs. Additional results for the individual TWTAs will be presented (AM/AM, AM/PM conversion and gain compression), some of which were obtained from swept frequency and power measurements using a vector network

    The focus of the FP7-EU project iSOIL “Interactions between soil related sciences - Linking geophysics, soil science and digital soil mapping” is to develop new and to improve existing strategies and innovative methods for generating accurate, high-resolution soil property maps. Thus we will develop, validate, and evaluate concepts and strategies for transferring measured physical parameter distributions into soil property, soil function and soil threat maps of different scales. The resulting soil property maps can be used for agriculture applications and soil degradation threats studies, e.g. erosion, compaction and soil organic matter decline. A fast and cost efficient way to detect physical parameters of soils at large areas is the application of mobile geophysical platforms. An advantage of these platforms is the flexibility since different kind of instruments can be mounted and combined. Following instruments are used on platforms within iSOIL project: EMI, GPR, gamma-spectrometry and magnetics. Since geophysical methods provide only physical parameters it is essential to combine them with conventional soil sampling methods for ground truthing. Physical parameters have to be converted into soil parameters via (site specific) transfer functions. One focus of the project was the development of measuring designs for the evaluation and combination of different geophysical methods. The application of a hierarchical approach is one way to combine different scales and parameters. The implementation of this approach will be presented and can be summarized as follows: - The first step is a survey of the total area with EMI and gamma-spectrometry. The distance between two lines is 10 - 20 meters. - By means of the geophysical data and a digital elevation model, representative soil sampling points are chosen, via a weighted conditioned latin hypercube sampling scheme (wLHS) based on conditioned latin hypercube sampling (cLHS). - All soil sampling points are probed

    A striking feature of the morphology of the Pyrenees is the occurrence of high-elevation, low-relief surfaces, which are interpreted as remnants of a single Miocene planation surface. Whether the original surface was uplifted or developed at high altitude is debated. This "Miocene Pyrenean peneplain" has been dissected by fluvial and glacial erosion during the Quaternary. Reworking by glacial erosion also provides new smooth surfaces such as glacial cirque floors that must not be confused with the remnants of the original planation surface. The later are convex-up landforms whereas glacial cirque floors are concave-up landforms. To reveal the Miocene high-elevation Pyrenean peneplain, we combined hand mapping and automatic mapping at the scale of the whole chain. From previous mapping in literature and from our own field work, we first perform a map of both the Miocene planation surface remnants and the Quaternary glacial cirque floors. Using Digital Elevation Models, numerical parameters were extracted from this map to characterize the two types of smooth surfaces. The slope is the parameter that helps to delimitate and differentiate the smooth surfaces from the rest of the Pyrenean topography. To distinguish between the two types of smooth surfaces we used the Topographic Index (TPI). This parameter is the difference between the elevation of a point and the mean elevation. Choosing the pertinent radius according to the scale of the landform to map, and the pertinent values interval, we can differentiate the planation surface (convex-up) from the glacial cirque floors (concave-up). A sensitivity test was performed to determine the best radius and the best interval for TPI and slope values to distinguish between the two types of smooth surfaces. Finally, we used a combination of slope values, TPI values and radius to determine automatically the high-elevation, low-relief surfaces in the entire Pyrenees. We verified in the field the presence of the newly mapped high

    NASA is currently carrying out science and technical studies to identify its next astronomy flagship mission, slated to begin development in the 2020s. It has become clear that a Large Ultraviolet/Optical/IR (LUVOIR) Surveyor mission (primary diameter 12 m, 1000 Ang - 2 micron spectroscopic bandpass) can carry out the largest number of NASA's exoplanet and astrophysics science goals over the coming decades. There are technical challenges for several aspects of the LUVOIR Surveyor concept, including component level technology readiness maturation and science instrument concepts for a broadly capable ultraviolet spectrograph. We present the scientific motivation for, and a preliminary design of, a multiplexed ultraviolet spectrograph to support both the exoplanet and astrophysics goals of the LUVOIR Surveyor mission concept, the Combined High-resolution and Imaging Spectrograph for the LUVOIR Surveyor (CHISL). CHISL includes a high-resolution (R 120,000; 1000 - 1700 Ang) point-source spectroscopy channel and a ...

  5. Combining Harmonic Generation and Laser Chirping to Achieve High Spectral Density in Compton Sources

    Terzić, Balša; Krafft, Geoffrey A

    2015-01-01

    Recently various laser-chirping schemes have been investigated with the goal of reducing or eliminating ponderomotive line broadening in Compton or Thomson scattering occurring at high laser intensities. As a next level of detail in the spectrum calculations, we have calculated the line smoothing and broadening expected due to incident beam energy spread within a one-dimensional plane wave model for the incident laser pulse, both for compensated (chirped) and unchirped cases. The scattered compensated distributions are treatable analytically within three models for the envelope of the incident laser pulses: Gaussian, Lorentzian, or hyperbolic secant. We use the new results to demonstrate that the laser chirping in Compton sources at high laser intensities: (i) enables the use of higher order harmonics, thereby reducing the required electron beam energies; and (ii) increases the photon yield in a small frequency band beyond that possible with the fundamental without chirping. This combination of chirping and h...

    A new sandwich sensor, consisting of an O-2 planar optode overlain by a thin (90 mu m) DGT layer is presented. This sensor can simultaneously resolve 2-D O-2 dynamics and trace metal fluxes in benthic substrates at a high spatial resolution. The DGT layer accumulates metals on a small particle size...... (0.2 mu m) chelating resin and records the locally induced trace metal flux during the deployment, whereas the planar optode resolves the O-2 dynamic in near real time at the same location in the sediment. Despite its ultrathin composition, the DGT layer has high carrying capacity for trace metals...... with no saturation problems during application to typical coastal-or contaminated sediments. Combined with laser ablation, accumulated metal fluxes could be resolved at a resolution of similar to 200 mu m, whereas the O-2 images had a resolution of similar to 100 mu m.

    HIV-1 mutation results in immune evasion, which presents a serious challenge for conventional strategies for developing effective vaccines.So far, much experimental evidence indicates that HIV-1 particles in the blood of patients can be cleaned principally by neutralizing antibodies.Based on these facts, we prepared triple combination of epitope-vaccines with the objective of inducing antibodies with predefined multi-epitope-specificity against HIV-1.According to the sequences of three neutralizing epitopes (RILAVERYLKD, ELDKWA and GPGRAFY, designated E1, E2, and E3, respectively) on HIV-1 envelope proteins, three epitope-peptides ((E1)2: C-(RILAVERYLKDG)2; (E2)4: C-(ELDKWAG)4; and (E3)2: C-(GPGRAFY)2) were synthesized and then conjugated with carrier protein keyhole limpet hemocyanin (KLH) or bovine serum albumin (BSA), and used for immunizing rabbits.After the vaccine course, the triple combination of epitope-vaccines induced high levels of predefined multi-epitope-specific antibodies.An immunoblotting-analysis demonstrated that the antibodies could recognize the native epitopes on both gp41 protein and V3 loop peptide.Furthermore, we compared the immune responses of three doses of epitope-peptides in the candidate epitope-vaccine.Strong antibody responses to three epitopes were observed in a dose dependent manner, with increasing dose raising the immune response.This result indicated that immunotolerance did not occur using an epitope vaccine dose of 80 μg.Thus, our results demonstrate that epitope-vaccines in combination can synchronously induce high levels of antibodies with predefined multi-epitope-specificity against HIV-1, and may be used to develop effective vaccines against HIV as a new strategy.

    Image-guided radiotherapy (IGRT) has been integrated into daily clinical routine and can today be considered the standard especially with high-dose radiotherapy. Currently imaging is based on MV- or kV-CT, which has clear limitations especially in soft-tissue contrast. Thus, combination of magnetic resonance (MR) imaging and high-end radiotherapy opens a new horizon. The intricate technical properties of MR imagers pose a challenge to technology when combined with radiation technology. Several solutions that are almost ready for routine clinical application have been developed. The clinical questions include dose-escalation strategies, monitoring of changes during treatment as well as imaging without additional radiation exposure during treatment. (orig.) [German] Die bildgestuetzte Radiotherapie (''image guided radiotherapy'', IGRT) ist in die taegliche klinische Routine integriert und kann heute als Therapiestandard angesehen werden, insbesondere bei dosiseskalierten Strahlentherapiekonzepten. Die derzeitige Bildgebung basiert auf der MV- oder kV-CT, welche beide besonders in Bezug auf die Darstellung von Weichteilen Limitationen aufweisen. Aus diesem Grund ist die Kombination von Magnetresonanz-(MR-)Bildgebung und moderner Strahlentherapietechnik eine zukunftsweisende Entwicklung. Die speziellen technischen Eigenschaften von MR-Scannern bringen eine grosse Herausforderung mit sich, wenn sie mit hochmodernen Strahlentherapiegeraeten kombiniert werden sollen. Eine Reihe technischer Loesungen sind entwickelt worden, die kurz vor dem klinischen Einsatz stehen. Die klinischen Fragestellungen umfassen unter anderem Strategien zur Dosiseskalation, Ueberwachung von Gewebeveraenderungen waehrend einer Strahlentherapie sowie Bildgebung unter Therapie ohne zusaetzliche Dosisapplikation.

    In this paper, a new combined method of sub-micron high aspect ratio structure fabrication is developed which can be used for production of nano imprint template. The process includes atomic force microscope (AFM) scratch nano-machining and reactive ion etching (RIE) fabrication. First, 40 nm aluminum film was deposited on the silicon substrate by magnetron sputtering, and then sub-micron grooves were fabricated on the aluminum film by nano scratch using AFM diamond tip. As aluminum film is a good mask for etching silicon, high aspect ratio structures were finally fabricated by RIE process. The fabricated structures were studied by SEM, which shows that the grooves are about 400 nm in width and 5 microm in depth. To obtain sub-micron scale groove structures on the aluminum film, experiments of nanomachining on aluminum films under various machining conditions were conducted. The depths of the grooves fabricated using different scratch loads were also studied by the AFM. The result shows that the material properties of the film/substrate are elastic-plastic following nearly a bilinear law with isotropic strain hardening. Combined AFM nanomachining and RIE process provides a relative lower cost nano fabrication technique than traditional e-beam lithography, and it has a good prospect in nano imprint template fabrication.

    2016-06-01

    To compensate for the gain saturation effect in the high-energy laser amplifier, a modified polarization beam combination (PBC) method is introduced to reshape temporal waveform of the injected laser pulse to obtain a controlled high-energy laser pulse shape after amplification. One linearly polarized beam is divided into two orthogonal polarized beams, which spatially recombine together collinearly after propagating different optical paths with relative time delay in PBC structure. The obtained beam with polarization direction being rotated by the following half wave plate is divided and combined again to reform a new beam in another modified polarization beam structure. The reformed beam is injected into three cascaded laser amplifiers. The amplified pulse shape can be controlled by the incident pulse shape and amplifier gain, which is agreeable to the simulation by the Frank-Nodvik equations. Based on the simple method, the various temporal waveform of output pulse with tunable 7 to 20 ns pulse duration can be obtained without interferometric fringes.

    We report a coherent combining of four slab laser amplifiers with high beam quality. The long strip laser beam is reshaped into a square beam using adjustable beam expander which removes the enormous astigmatism aberration. A filling ratio of 90% is achieved by two-dimensional splicing. A compact optical system with high sampling frequency is designed to detect the pointing direction of lasers. Fast steering mirror (FSM) driven by piezoelectric ceramics is applied in laser stabilizing. Thanks to the closed loop pointing control, the root mean square error of the optical axis is significantly reduced to be less than 2 microradians. The piston phases of the lasers are locked by an active phase control system based on Field Programmable Gate Array (FPGA) using stochastic parallel gradient descent (SPGD) algorithm. When the total output power of four lasers is 400W, the in-phase peak intensity of the far field spot is increased by a factor of 3.8, reaching 95% of the ideal case. The beam quality of the combined beam is improved by CBC from 1.52x diffraction limit (DL) to 1.26x DL. When the output power is increased to 805W, the phase locking and pointing control still work stably. The results suggest that CBC of solid-state lasers with higher energy could be achieved by using the techniques presented here.

    Full Text Available Zebu cattle fed high concentrate diets may present inconsistent performance due to the occurrence of metabolic disorders, like acidosis. The isolated use of ionophores and virginiamycin in high grain diets can improve animal performance and reduce the incidence of such disorders, but recent studies suggested that their combination may have an additive effect. Thus, 72 Nellore steers, 389 ± 15 kg initial body weight (BW, were confined and fed for 79 days to evaluate the combination of virginiamycin and salinomycin on performance and carcass traits. Animals were allocated to a randomized complete block design by BW, in a 2 × 2 factorial arrangement of treatments, with two concentrate levels (73 and 91 % and two virginiamycin levels (0 and 15 mg kg-1, and salinomycin (13 mg kg-1 included in all diets. The interaction was not significant (p > 0.05. Dry matter intake (DMI, average daily gain (ADG, gain-to-feed ratio (G:F, starch consumed, and fecal starch content were higher (p 0.05 between treatments. Starch consumed and estimated dietary net energy for maintenance (NEm and gain (NEg were higher (p < 0.05 for virginiamycin-treated animals, with no substantial effects on carcass traits. The inclusion of virginiamycin in finishing diets containing salinomycin reduced DMI while maintaining ADG and improving NEm and NEg, suggesting an additive effect of virginiamycin and ionophores, but without affecting carcass quality.

    This study examined the associations between conscientious perfectionism (high standards), self-evaluative perfectionism (self-criticism) and eating psychopathology among dancers. A sample of 244 female dancers, with a mean age of 20.11 years (standard deviation=1.97) completed the Perfectionism Inventory and Eating Disorder Examination Questionnaire. Self-evaluative perfectionism predicted eating psychopathology (eating restraint, eating concern, weight concern and shape concern). This relationship was not moderated by conscientious perfectionism. The mediation analyses showed that although conscientious perfectionism predicted eating psychopathology, this relationship was fully mediated by self-evaluative perfectionism. These findings demonstrate the greater influence of self-evaluative perfectionism, rather than conscientious perfectionism, on eating psychopathology in dancers.

    Individuals differ in their timing of sleep (bed times, rise times) and in their preference for morning or evening hours. Previous work focused on the relationship between academic achievement and these variables in secondary school students. The main aim of the study is to investigate the relationship between chronotype and academic achievement in 10-year-old children (n = 1125) attending 4th grade of primary school. They filled a cognitive test (Culture Fair Intelligence Test, CFT 20-R) and questions about rise times and bed times, academic achievement, conscientiousness and motivation. We used the "scales for the assessment of learning and performance motivation" (SELLMO; Skalen zur Erfassung der Lern- und Leistungsmotivation for motivation), the short version of the Five-Factor Personality Inventory Children (FFPI-C) to measure conscientiousness, and the Composite Scale of Morningness (CSM) to assess morningness-eveningness. Mean CSM score was 37.84 ± 6.66, midpoint of sleep was 1:36 ± 00:25 and average sleep duration (time in bed) was 10:15 ± 0:48. Morningness orientation was positively related to intelligence, conscientiousness and learning objectives. Eveningness orientation was related to avoidance performance objectives and work avoidance. Early midpoint of sleep, conscientiousness and intelligence were associated with better grades. The multivariate model showed that intelligence was the strongest predictor of good grades. Conscientiousness, motivation, younger age and an earlier midpoint of sleep were positively related to good grades. This is the first study in primary school pupils, and it shows that the relationship between evening orientation and academic achievement is already prevalent at this age even when controlling for important predictors of achievement.

    The aim of this study was to develop an alternative, more bio-available, better tolerated paclitaxel nanosuspension (PTXNS) for intravenous injection in comparison with commercially available Taxol(®) formulation. In this study, PTXNS was prepared by emulsification method through combination of high speed homogenizer and high pressure homogenization, followed by lyophilization process for intravenous administration. The main production parameters including volume ratio of organic phase in water and organic phase (Vo:Vw+o), concentration of PTX, content of PTX and emulsification time (Et), homogenization pressure (HP) and passes (Ps) for high pressure homogenization were optimized and their effects on mean particle size (MPS) and particle size distribution (PSD) of PTXNS were investigated. The characteristics of PTXNS, such as, surface morphology, physical status of paclitaxel (PTX) in PTXNS, redispersibility of PTXNS in purified water, in vitro dissolution study and bioavailability in vivo were all investigated. The PTXNS obtained under optimum conditions had an MPS of 186.8 nm and a zeta potential (ZP) of -6.87 mV. The PTX content in PTXNS was approximately 3.42%. Moreover, the residual amount of chloroform was lower than the International Conference on Harmonization limit (60 ppm) for solvents. The dissolution study indicated PTXNS had merits including effect to fast at the side of raw PTX and sustained-dissolution character compared with Taxol(®) formulation. Moreover, the bioavailability of PTXNS increased 14.38 and 3.51 times respectively compared with raw PTX and Taxol(®) formulation.

    Stearidonic acid (SDA), an n-3 polyunsaturated fatty acid (PUFA), can be obtained from plant origin oils and it can be a good source of PUFA for vegetarians. SDA can be easily converted to longer PUFA such as docosahexaenoic acid and eicosapentaenoic acid. Highly purified stearidonic acid (SDA) was prepared successfully from echium oil via an enzymatic method combined with preparative high performance liquid chromatography. In the 1(st) step, SDA enrichment was accomplished using Candida rugosa lipase and 39.5% of SDA was obtained in the fatty acid fraction. Subsequently, the 1(st) reaction mixture was used for the 2(nd) enzymatic esterification without any separation process. The 2(nd) esterification was conducted for further SDA enrichment in a packed-bed reactor using Lipozyme RM IM from Rhizomucor miehei and the SDA content increased in a very short residence time. Ethanol was selected as an appropriate alcohol to react as an acyl receptor, and the other conditions for SDA enrichment were optimized at 20°C of temperature, and 1:4 of molar ratio (i.e., fatty acid to ethanol). Under these conditions, 51.6% of SDA was obtained in the fatty acid fraction after a residence time of 15 min. Finally, highly purified SDA (purity, >99%) was obtained by prep-HPLC using the SDA-rich fraction obtained from the two-step lipase-catalyzed esterification.

    In this investigation, we have designed and synthesized a novel core-shell polymer nanoparticle system for highly effective chemo-photothermal combination therapy. A nanoscale DSPE-PEG micelle encapsulating doxorubicin (Dox-M) was designed as a core, and then modified by a polydopamine (PDA) shell for photothermal therapy and bortezomib (Btz) administration (Dox-M@PDA-Btz). The facile conjugation of Btz to the catechol-containing PDA shell can form a reversible pH-sensitive boronic acid-catechol conjugate to create a stimuli-responsive drug carrier system. As expected, the micelle@PDA core-shell nanoparticles exhibited satisfactory photothermal efficiency, which has potential for thermal ablation of malignant tissues. In addition, on account of the PDA modification, both Dox and Btz release processes were pH-dependent and NIR-dependent. Both in vitro and in vivo studies illustrated that the Dox-M@PDA-Btz nanoparticles coupled with laser irradiation could enhance the cytotoxicity, and thus combinational therapy efficacy was achieved when integrating Dox, Btz, and PDA into a single nanoplatform. Altogether, our current study indicated that the micelle@polydopamine core-shell nanoparticles could be applied for NIR/pH-responsive sustained-release and synergized chemo-photothermal therapy for breast cancer.In this investigation, we have designed and synthesized a novel core-shell polymer nanoparticle system for highly effective chemo-photothermal combination therapy.

    Laser power and brightness scaling, in "eye safe" atmospheric transmission windows, is driving laser system research and development. High power lasers with good beam quality, at wavelength around 2.1 µm, are necessary for optical countermeasure applications. For such applications, focusing on efficiency and compactness of the system is mandatory. In order to cope with these requirements, one must consider the use of laser diodes which emit directly in the desired spectral region. The challenge for these diodes is to maintain a good beam quality factor as the output power increases. 2 µm diodes with excellent beam quality in both axes are available with output powers of 100 mW. Therefore, in order to reach multi-watt of average output power, broad-area single emitters and beam combining becomes relevant. Different solutions have been implemented in the 1.9 to 2 µm wavelength range, one of which is to stack multiple emitter bars reaching more than one hundred watt, while another is a fibre coupled diode module. The beam propagation factor of these systems is too high for long atmospheric propagation applications. Here we describe preliminary results on non-coherent beam combining of 2.1 µm high power Fabry-Perot GaSb laser diodes supplied by Brolis Semiconductors Ltd. First we evaluated single mode diodes (143 mW) with good beam quality (M2 beam consisted of two symmetric lobes with a total full width at half maximum (FWHM) divergence angle of 25 degrees, corresponding to a calculated beam quality factor of M2 = 25. The fast axis divergence was specified to be 44 degrees, with an expected beam quality factor close to the diffraction limit, which informed our selection of collimation lenses used in the experiment. We evaluated two broadband (1.8 - 3 µm) AR coated Geltech aspheric lenses with focal lengths of 1.87 mm and 4 mm, with numerical apertures of 0.85 and 0.56, respectively, as an initial collimation lens, followed by an additional cylindrical lens of

    Modelling the development of soils in glacier forefields is necessary in order to assess how microbial and geochemical processes interact and shape soil development in response to glacier retreat. Furthermore, such models can help us predict microbial growth and the fate of Arctic soils in an increasingly ice-free future. Here, for the first time, we combined field sampling with laboratory analyses and numerical modelling to investigate microbial community dynamics in oligotrophic proglacial soils in Svalbard. We measured low bacterial growth rates and growth efficiencies (relative to estimates from Alpine glacier forefields) and high sensitivity of bacterial growth rates to soil temperature (relative to temperate soils). We used these laboratory measurements to inform parameter values in a new numerical model and significantly refined predictions of microbial and biogeochemical dynamics of soil development over a period of roughly 120 years. The model predicted the observed accumulation of autotrophic and heterotrophic biomass. Genomic data indicated that initial microbial communities were dominated by bacteria derived from the glacial environment, whereas older soils hosted a mixed community of autotrophic and heterotrophic bacteria. This finding was simulated by the numerical model, which showed that active microbial communities play key roles in fixing and recycling carbon and nutrients. We also demonstrated the role of allochthonous carbon and microbial necromass in sustaining a pool of organic material, despite high heterotrophic activity in older soils. This combined field, laboratory, and modelling approach demonstrates the value of integrated model-data studies to understand and quantify the functioning of the microbial community in an emerging High Arctic soil ecosystem.

    Full Text Available Introduction: High-grade gynaecomastia (Simon IIb and III has tissue excess (skin excess, enlarged areola, and displaced nipple, which is best managed surgically; however, results of conventional breast reduction surgeries and liposuction is not very good. Aim of our study was to describe a combined technique to manage these problems to produce a good result. Material and Method: This was a 2-year study among 12 patients of high grade gynaecomastia. Clinical and laboratory findings were normal. Pre-operatively in standing position, diameter of breast and areola, position of nipple, and amount of skin excess were marked. Under general anaesthesia, tumescent infiltration, circumareolar de-epithelisation of skin excess, and liposuction was completed. Redundant portion of the breast was sharply dissected and pulled out. Areola was fixed over pectoralis fascia at mid humerus level, just medial to the mid-clavicular line. Outer borders of the de-epithelised area were apposed by the purse-string effect of a subdermal suture, and further apposed by few half buried horizontal mattress sutures. Drains for 24 hour and compressive dressings for 6 weeks were used. Result: Mean age of presentation was 25.8 year; emotional discomfort was the chief complaint. Among 12 patients, 10 patients had bilateral gynaecomastia and 8 patients had enlarged and displaced nipple-areola complex. Average hospital stay was 2.41 days and recoveries were usually uneventful. Conclusion: The problem of tissue excess and tissue displacement in high grade gynaecomastia can be well managed by this combined circumareolar skin reduction and liposuction technique to achieve a scar-less flat male chest.

    A high-temperature gas-steam turbine plant (GSTP) for ultrasupercritical steam conditions is proposed based on an analysis of prospects for the development of power engineering around the world and in Russia up to 2040. The performance indicators of a GSTP using steam from a coal-fired boiler with a temperature of 560-620°C with its superheating to 1000-1500°C by firing natural gas with oxygen in a mixingtype steam superheater are analyzed. The thermal process circuit and design of a GSTP for a capacity of 25 MW with the high- and intermediate-pressure high-temperature parts with the total efficiency equal to 51.7% and the natural gas utilization efficiency equal to 64-68% are developed. The principles of designing and the design arrangement of a 300 MW GSTP are developed. The effect of economic parameters (the level and ratio of prices for solid fuel and gas, and capital investments) on the net cost of electric energy is determined. The net cost of electric energy produced by the GSTP is lower than that produced by modern combined-cycle power plants in a wide variation range of these parameters. The components of a high-temperature GSTP the development of which determines the main features of such installations are pointed out: a chamber for combusting natural gas and oxygen in a mixture with steam, a vacuum device for condensing steam with a high content of nondensables, and a control system. The possibility of using domestically available gas turbine technologies for developing the GSTP's intermediate-pressure high-temperature part is pointed out. In regard of its environmental characteristics, the GSTP is more advantageous as compared with modern condensing power plants: it allows a flow of concentrated carbon dioxide to be obtained at its outlet, which can be reclaimed; in addition, this plant requires half as much consumption of fresh water.

    Full Text Available Abstract Background The primary goal of genetic linkage analysis is to identify genes affecting a phenotypic trait. After localisation of the linkage region, efficient genetic dissection of the disease linked loci requires that functional variants are identified across the loci. These functional variations are difficult to detect due to extent of genetic diversity and, to date, incomplete cataloguing of the large number of variants present both within and between populations. Massively parallel sequencing platforms offer unprecedented capacity for variant discovery, however the number of samples analysed are still limited by cost per sample. Some progress has been made in reducing the cost of resequencing using either multiplexing methodologies or through the utilisation of targeted enrichment technologies which provide the ability to resequence genomic areas of interest rather that full genome sequencing. Results We developed a method that combines current multiplexing methodologies with a solution-based target enrichment method to further reduce the cost of resequencing where region-specific sequencing is required. Our multiplex/enrichment strategy produced high quality data with nominal reduction of sequencing depth. We undertook a genotyping study and were successful in the discovery of novel SNP alleles in all samples at uniplex, duplex and pentaplex levels. Conclusion Our work describes the successful combination of a targeted enrichment method and index barcode multiplexing to reduce costs, time and labour associated with processing large sample sets. Furthermore, we have shown that the sequencing depth obtained is adequate for credible SNP genotyping analysis at uniplex, duplex and pentaplex levels.

  9. Combining Superdirective Beamforming and Frequency-Domain Blind Source Separation for Highly Reverberant Signals

    2010-01-01

    Full Text Available Frequency-domain blind source separation (BSS performs poorly in high reverberation because the independence assumption collapses at each frequency bins when the number of bins increases. To improve the separation result, this paper proposes a method which combines two techniques by using beamforming as a preprocessor of blind source separation. With the sound source locations supposed to be known, the mixed signals are dereverberated and enhanced by beamforming; then the beamformed signals are further separated by blind source separation. To implement the proposed method, a superdirective fixed beamformer is designed for beamforming, and an interfrequency dependence-based permutation alignment scheme is presented for frequency-domain blind source separation. With beamforming shortening mixing filters and reducing noise before blind source separation, the combined method works better in reverberation. The performance of the proposed method is investigated by separating up to 4 sources in different environments with reverberation time from 100 ms to 700 ms. Simulation results verify the outperformance of the proposed method over using beamforming or blind source separation alone. Analysis demonstrates that the proposed method is computationally efficient and appropriate for real-time processing.

    We examined the clinical response of fludarabine-refractory CLL patients treated with high-dose methylprednisolone (HDMP) and rituximab. Fourteen patients were treated with three cycles of rituximab (375mg/m2 weekly for 4 weeks) in combination with HDMP (1gm/m2 daily for 5 days). All patients were refractory to fludarabine and 86% had high-risk disease by the modified Rai classification. In all, 79% of the patients had CLL cells that expressed ZAP-70 and three patients had poor prognostic cytogenetics. The overall response rate was 93% and the complete remission rate was 36%. The median time-to-progression was 15 months and the median time-to-next treatment was 22 months. Median survival has not been reached after a median follow up of 40 months. Four patients have died of progressive disease. Patients tolerated the treatment well and serious adverse events were rare. This allowed patients to receive all planned treatments on schedule with no dose modifications. All but one patient responded to treatment and the overall survival and time-to-progression were superior to those of other published salvage regimens. PMID:18754025

  11. A novel algorithm combining oversampling and digital lock-in amplifier of high speed and precision.

    2011-09-01

    Because of a large amount of arithmetic in the standard digital lock-in detection, a high performance processor is needed to implement the algorithm in real time. This paper presents a novel algorithm that integrates oversampling and high-speed lock-in detection. The algorithm sets the sampling frequency as a whole-number multiple of four of the input signal frequency, and then uses the common downsampling technology to lower the sampling frequency to four times of the input signal frequency. It could effectively remove the noise interference and improve the detection accuracy. After that the phase sensitive detector is implemented. It simply does the addition and subtraction on four points in the period of same phase and replaces almost all the multiplication operations to speed up digital lock-in detection calculation substantially. Furthermore, the correction factor is introduced to improve the calculation accuracy of the amplitude, and an error caused by the algorithm in theory can be eliminated completely. The results of the simulation and actual experiments show that the novel algorithm combining digital lock-in detection and oversampling not only has the high precision, but also has the unprecedented speed. In our work, the new algorithm is suitable for the real-time weak signal detection in the general microprocessor not just digital signal processor.

    A new high-voltage array comprising bipolar strings of copper indium gallium diselenide (CIGS) photovoltaic (PV) modules was inaugurated in 2005. It is equipped with a unique combination of tests, which likely have never before been deployed simultaneously within a single array: full current-voltage (I-V) traces, high-voltage leakage current measurements, and peak-power tracking or temporal stepped-bias profiling. The array nominally produces 1 kW power at 1 sun. The array's electrical characteristics are continuously monitored and controlled with a programmable electronic load interfaced to a data acquisition system (DAS), that also records solar and meteorological data. The modules are mounted with their frames electrically isolated from earth ground, in order to facilitate measurement of the leakage currents that arise between the high voltage bias developed in the series-connected cells and modules and their mounting frames. Because the DAS can perform stepped biasing of the array as a function of time, synchronous detection of the leakage current data with alternating bias is available. Leakage current data and their dependence on temperature and voltage are investigated. Array power data are analyzed across a wide range of varying illuminations and temperatures from the I-V traces. Array performance is also analyzed from an energy output perspective using peak-power tracking data.

    Chirality in microcavities has recently shown its bright future in optical sensing and microsized coherent light sources. The key parameters for such applications are the high quality (Q) factor and large chirality. However, the previous reported chiral resonances are either low Q modes or require very special cavity designs. Here we demonstrate a novel, robust, and general mechanism to obtain the chirality in circular cavity. By placing a circular cavity and a spiral cavity in proximity, we show that ultra-high Q factor, large chirality, and unidirectional output can be obtained simultaneously. The highest Q factors of the non-orthogonal mode pairs are almost the same as the ones in circular cavity. And the co-propagating directions of the non-orthogonal mode pairs can be reversed by tuning the mode coupling. This new mechanism for the combination of high Q factor and large chirality is found to be very robust to cavity size, refractive index, and the shape deformation, showing very nice fabrication tolerance. And it can be further extended to microcavity chain and microcavity plane. We believe that our research will shed light on the practical applications of chirality and microcavities.

    Genome-wide association study is especially challenging in detecting high-order disease-causing models due to model diversity, possible low or even no marginal effect of the model, and extraordinary search and computations. In this paper, we propose a niche harmony search algorithm where joint entropy is utilized as a heuristic factor to guide the search for low or no marginal effect model, and two computationally lightweight scores are selected to evaluate and adapt to diverse of disease models. In order to obtain all possible suspected pathogenic models, niche technique merges with HS, which serves as a taboo region to avoid HS trapping into local search. From the resultant set of candidate SNP-combinations, we use G-test statistic for testing true positives. Experiments were performed on twenty typical simulation datasets in which 12 models are with marginal effect and eight ones are with no marginal effect. Our results indicate that the proposed algorithm has very high detection power for searching suspected disease models in the first stage and it is superior to some typical existing approaches in both detection power and CPU runtime for all these datasets. Application to age-related macular degeneration (AMD) demonstrates our method is promising in detecting high-order disease-causing models.

    Robust hydrological modelling of high mountain catchments to support water resources management depends critically on the accuracy of climatic input data. However, the hydroclimatological complexity and sparse measurement networks typically characteristic of these environments present significant challenges for determining the structure of spatial and temporal variability in key climatic variables. Focusing on the Upper Indus Basin (UIB), this research explores how different data sources can be combined in order to characterise climatic patterns and related uncertainties at the scales required in hydrological modelling. Analysis of local observations with respect to underlying climatic processes and variability is extended relative to previous studies in this region, which forms a basis for evaluating the domains of applicability and potential insights associated with selected remote sensing and reanalysis products. As part of this, the information content of recent high resolution simulations for understanding climatic patterns is assessed, with particular reference to the High Asia Refined Analysis (HAR). A strategy for integrating these different data sources to obtain plausible realisations of the distributed climatic fields needed for hydrological modelling is developed on the basis of this analysis, which provides a platform for exploring uncertainties arising from potential biases and other sources of error. The interaction between uncertainties in climatic input data and alternative approaches to process parameterisation in hydrological and cryospheric modelling is explored.

  16. Combination of various data analysis techniques for efficient track reconstruction in very high multiplicity events

    2017-08-01

    A novel combination of established data analysis techniques for reconstructing charged-particles in high energy collisions is proposed. It uses all information available in a collision event while keeping competing choices open as long as possible. Suitable track candidates are selected by transforming measured hits to a binned, three- or four-dimensional, track parameter space. It is accomplished by the use of templates taking advantage of the translational and rotational symmetries of the detectors. Track candidates and their corresponding hits, the nodes, form a usually highly connected network, a bipartite graph, where we allow for multiple hit to track assignments, edges. In order to get a manageable problem, the graph is cut into very many minigraphs by removing a few of its vulnerable components, edges and nodes. Finally the hits are distributed among the track candidates by exploring a deterministic decision tree. A depth-limited search is performed maximizing the number of hits on tracks, and minimizing the sum of track-fit χ2. Simplified but realistic models of LHC silicon trackers including the relevant physics processes are used to test and study the performance (efficiency, purity, timing) of the proposed method in the case of single or many simultaneous proton-proton collisions (high pileup), and for single heavy-ion collisions at the highest available energies.

    Subvalvular aortic stenosis (SAS) is one of the most common congenital cardiac malformations in dogs. Unfortunately, the long term success rate and survival data following either open heart surgery or catheter based intervention has been disappointing in dogs with severe subaortic stenosis. Medical therapy is currently the only standard recommended treatment option. A cutting balloon dilation catheter has been used successfully for resistant coronary artery and peripheral pulmonary arterial stenoses in humans. This catheter is unique in that it has the ability to cut, or score, the stenotic region prior to balloon dilatation of the stenosis. The use of cutting balloon valvuloplasty combined with high pressure valvuloplasty for dogs with severe subaortic stenosis has recently been reported to be a safe and feasible alternative therapeutic option. The following report describes this technique, outlines the materials required, and provides some 'tips' for successful percutaneous subaortic balloon valvuloplasty. Copyright © 2012 Elsevier B.V.

    The efficacy of combined high-dose steroid and PGE1 treatment initiated immediately after the onset of sudden deafness was analyzed with the outcome of 174 patients begun on treatment within 7 days of the onset of sudden deafness. Four potential prognostic factors (days from onset to treatment, age, initial hearing level, presence of vertigo) and hearing outcome were examined with a multiple logistic regression analysis. Days from onset to treatment and age significantly correlated with hearing improvement. The efficacy of the treatment of patients begun on treatment within 3 days of the onset was significantly better than that of patients on treatment 4-7 days after the onset (p sudden deafness, and started within 3 days of the onset of sudden deafness in patients 50 years old and older.

    Lanusse, Francois; Leonard, Adrienne; Pires, Sandrine

    2016-01-01

    We propose a new mass-mapping algorithm, specifically designed to recover small-scale information from a combination of gravitational shear and flexion. Including flexion allows us to supplement the shear on small scales in order to increase the sensitivity to substructures and the overall resolution of the convergence map without relying on strong lensing constraints. In order to preserve all available small scale information, we avoid any binning of the irregularly sampled input shear and flexion fields and treat the mass-mapping problem as a general ill-posed inverse problem, regularised using a robust multi-scale wavelet sparsity prior. The resulting algorithm incorporates redshift, reduced shear, and reduced flexion measurements for individual galaxies and is made highly efficient by the use of fast Fourier estimators. We test our reconstruction method on a set of realistic weak lensing simulations corresponding to typical HST/ACS cluster observations and demonstrate our ability to recover substructures ...

  20. Pediatric Bipolar Disorder: Combination Pharmacotherapy, Adverse Effects, and Treatment of High-Risk Youth.

    Science.gov (United States)

    Chang, Kiki D

    2016-01-01

    Treating bipolar disorder in pediatric patients is challenging because data from rigorous trials of pharmacotherapy in this population are still not plentiful enough. Furthermore, the treatment of children and adolescents is complicated by the frequent need to combine pharmacotherapies to address all bipolar symptoms as well as this population's elevated risk for experiencing side effects. Additionally, young patients with depressive episodes who are at high risk for developing bipolar disorder need careful treatment to prevent or delay the emergence of mania. Despite these challenges, clinicians should evaluate the existing pediatric literature, extrapolate evidence obtained from adult patients, and draw from clinical experience to guide treatment decisions for children and adolescents with bipolar disorder. © Copyright 2016 Physicians Postgraduate Press, Inc.

    Burress, Jacob; Bethea, Donald; Troub, Brandon

    2017-05-01

    The accurate measurement of adsorbed gas up to high pressures (˜100 bars) is critical for the development of new materials for adsorbed gas storage. The typical Sievert-type volumetric method introduces accumulating errors that can become large at maximum pressures. Alternatively, gravimetric methods employing microbalances require careful buoyancy corrections. In this paper, we present a combination gravimetric and volumetric system for methane sorption measurements on samples between ˜0.5 and 1 g. The gravimetric method described requires no buoyancy corrections. The tandem use of the gravimetric method allows for a check on the highest uncertainty volumetric measurements. The sources and proper calculation of uncertainties are discussed. Results from methane measurements on activated carbon MSC-30 and metal-organic framework HKUST-1 are compared across methods and within the literature.

METHODS: Sixty(120 eyeshigh myopia combined with cataract cases received phacoemulsification and intraocular lens implantation in our hospital were retrospective studied. The patients were divided into three groups based on postoperative diopter: -1.0~-2.0D(group A, -2.25~-3.0D(group Band -3.25~-4.0D(group C. The uncorrected distance visual acuity(UCDVA, best corrected distant visual acuity(BCDVA, uncorrected near visual acuity(UCNVAand questionnaire of Activities of Daily Vision Scale(ADVSwere collected to assess the vision gain at 3mo after cataract surgery. RESULTS: At 3mo after surgery, UCDVA of group A was better than that of group B, and UCDVA of group B was better than that of group C. There were no differences in BCDVA among groups. There were significant differences between the three groups' UCNVA, it was best for the group C, followed by the group B, group A was the worst. For questionnaire, no difference was observed in patients' satisfactory for surgical results, but a significant difference was detected in postoperative glasses wearing frequency between groups. CONCLUSION:For cataract surgery in high myopia combined cataract, postoperative diopter should be calculated based on patients' daily requirements. For patients had not used to wearing glasses and near distant working condition, it's appropriated to reserve a minor degree of myopia. Conversely, for patients require near distant working and received wearing moderate and low hyperopia mirror, higher degree of myopia can be reserved.

    PurposeTo retrospectively evaluate the effectiveness of computed tomography-guided percutaneous microwave ablation (MWA) and cementoplasty in patients with painful bone metastases at high risk of fracture.Materials and MethodsThirty-five patients with 37 metastatic bone lesions underwent computed tomography-guided MWA combined with cementoplasty (polymethylmethacrylate injection). Vertebrae, femur, and acetabulum were the intervention sites and the primary end point was pain relief. Pain severity was estimated by visual analog scale (VAS) before treatment; 1 week post-treatment; and 1, 6, and 12 months post-treatment. Functional outcome was assessed by improved patient walking ability. Radiological evaluation was performed at baseline and 3 and 12 months post-procedure.ResultsIn all patients, pain reduction occurred from the first week after treatment. The mean reduction in the VAS score was 84, 90, 90 % at week 1, month 1, and month 6, respectively. Improved walking ability occurred in 100 and 98 % of cases at the 1- and 6-month functional outcome evaluations, respectively. At the 1-year evaluation, 25 patients were alive, and 10 patients (28 %) had died because of widespread disease. The mean reduction in the VAS score and improvement in surviving patients’ walking ability were 90 and 100 %, respectively. No patients showed evidence of local tumor recurrence or progression and pathological fracture in the treated sites.ConclusionOur results suggest that MWA combined with osteoplasty is safe and effective when treating painful bone metastases at high risk of fracture. The number of surviving patients at the 1-year evaluation confirms the need for an effective and long-lasting treatment.

  7. High-resolution combined global gravity field modelling: Solving large kite systems using distributed computational algorithms

    Science.gov (United States)

    Zingerle, Philipp; Fecher, Thomas; Pail, Roland; Gruber, Thomas

    2016-04-01

    One of the major obstacles in modern global gravity field modelling is the seamless combination of lower degree inhomogeneous gravity field observations (e.g. data from satellite missions) with (very) high degree homogeneous information (e.g. gridded and reduced gravity anomalies, beyond d/o 1000). Actual approaches mostly combine such data only on the basis of the coefficients, meaning that previously for both observation classes (resp. models) a spherical harmonic analysis is done independently, solving dense normal equations (NEQ) for the inhomogeneous model and block-diagonal NEQs for the homogeneous. Obviously those methods are unable to identify or eliminate effects as spectral leakage due to band limitations of the models and non-orthogonality of the spherical harmonic base functions. To antagonize such problems a combination of both models on NEQ-basis is desirable. Theoretically this can be achieved using NEQ-stacking. Because of the higher maximum degree of the homogeneous model a reordering of the coefficient is needed which leads inevitably to the destruction of the block diagonal structure of the appropriate NEQ-matrix and therefore also to the destruction of simple sparsity. Hence, a special coefficient ordering is needed to create some new favorable sparsity pattern leading to a later efficient computational solving method. Such pattern can be found in the so called kite-structure (Bosch, 1993), achieving when applying the kite-ordering to the stacked NEQ-matrix. In a first step it is shown what is needed to attain the kite-(NEQ)system, how to solve it efficiently and also how to calculate the appropriate variance information from it. Further, because of the massive computational workload when operating on large kite-systems (theoretically possible up to about max. d/o 100.000), the main emphasis is put on to the presentation of special distributed algorithms which may solve those systems parallel on an indeterminate number of processes and are

  11. Combining isothermal rolling circle amplification and electrochemiluminescence for highly sensitive point mutation detection

    Su, Qiang; Zhou, Xiaoming

    2008-12-01

    Many pathogenic and genetic diseases are associated with changes in the sequence of particular genes. We describe here a rapid and highly efficient assay for the detection of point mutation. This method is a combination of isothermal rolling circle amplification (RCA) and high sensitive electrochemluminescence (ECL) detection. In the design, a circular template generated by ligation upon the recognition of a point mutation on DNA targets was amplified isothermally by the Phi29 polymerase using a biotinylated primer. The elongation products were hybridized with tris (bipyridine) ruthenium (TBR)-tagged probes and detected in a magnetic bead based ECL platform, indicating the mutation occurrence. P53 was chosen as a model for the identification of this method. The method allowed sensitive determination of the P53 mutation from wild-type and mutant samples. The main advantage of RCA-ECL is that it can be performed under isothermal conditions and avoids the generation of false-positive results. Furthermore, ECL provides a faster, more sensitive, and economical option to currently available electrophoresis-based methods.

  12. Boechera species exhibit species-specific responses to combined heat and high light stress.

    Gallas, Genna; Waters, Elizabeth R

    2015-01-01

    As sessile organisms, plants must be able to complete their life cycle in place and therefore tolerance to abiotic stress has had a major role in shaping biogeographical patterns. However, much of what we know about plant tolerance to abiotic stresses is based on studies of just a few plant species, most notably the model species Arabidopsis thaliana. In this study we examine natural variation in the stress responses of five diverse Boechera (Brassicaceae) species. Boechera plants were exposed to basal and acquired combined heat and high light stress. Plant response to these stresses was evaluated based on chlorophyll fluorescence measurements, induction of leaf chlorosis, and gene expression. Many of the Boechera species were more tolerant to heat and high light stress than A. thaliana. Gene expression data indicates that two important marker genes for stress responses: APX2 (Ascorbate peroxidase 2) and HsfA2 (Heat shock transcription factor A2) have distinct species-specific expression patterns. The findings of species-specific responses and tolerance to stress indicate that stress pathways are evolutionarily labile even among closely related species.

    One of the main issues of the advances in optoacoustic (OA) applications is to reduce the high costs and the big sizes of solid state lasers. High-power diode lasers (HPDLs) have been demonstrated to be a valid alternative reducing enormously the expenses, besides other advantages such as smaller sizes and higher modulation frequencies. However, in some cases it is possible to furtherly reduce their costs. We present a cost-effective OA system based on the combination of several 905-nm HPDLs with direct coupling into a fiber bundle. These HPDLs have an internal pulse driver, based on an n-channel Mosfet and two charging capacitors, which needs an external Mosfet driver circuit and a voltage supply in order to improve the optical pulse shape and energy. We compare the performances and the prices of this OA system with another similar HPDL-based OA system built with commercial elements. Results indicate good OA signal generation ( 15.6 mVpp) with pulse energy of 12.3 μJ and, especially, a cost reduction by a factor of 15 if compared to the other HPDL-based system.

    Full Text Available Combinatorial screening used together with a broad library of gene expression cassettes is expected to produce a powerful tool for the optimization of the simultaneous expression of multiple enzymes. Recently, we proposed a highly tunable protein expression system that utilized multiple genome-integrated target genes to fine-tune enzyme expression in yeast cells. This tunable system included a library of expression cassettes each composed of three gene-expression control elements that in different combinations produced a wide range of protein expression levels. In this study, four gene expression cassettes with graded protein expression levels were applied to the expression of three cellulases: cellobiohydrolase 1, cellobiohydrolase 2, and endoglucanase 2. After combinatorial screening for transgenic yeasts simultaneously secreting these three cellulases, we obtained strains with higher cellulase expressions than a strain harboring three cellulase-expression constructs within one high-performance gene expression cassette. These results show that our method will be of broad use throughout the field of metabolic engineering.

    A new proportional navigation (PN) guidance law, called combined proportional navigation (CPN), is proposed. The guidance law is designed to intercept high-speed targets, which is a common case for ballistic targets. The range of target-to-interceptor speed ratio during target interception is derived when guidance laws are applied in high-speed targets interception, and the effectiveness of negative navigation ratio in the PN-based guidance law is proven analytically in some lemmas .Based on the lemmas, the lateral acceleration command of CPN is defined, and the solution to the appearance of singularity in time-varying navigation ratio is given. The simulation results show that CPN can determine head-on engagement (as PN) or tail-chase engagement (as RPN) through initial path angle compared with PN and retro proportional navigation (RPN), and can adjust the value of navigation ratio for head-on engagement or tail-chase engagement. Therefore, the capture region of CPN is larger than that of other guidance laws using PN-based methods.

    Research on the isolation and preparation of anthocyanins has intensified in recent years because of the requirements of quantitative and bioactive analyses. However, simple and effective methods for the scale purification of pure anthocyanins from natural products are rarely reported. In this study, high-purity anthocyanin mixtures and monomers were successfully isolated from wild blueberries using a combination of column chromatography and semi-preparative HPLC. We established an effective elution system to separate high-purity anthocyanin mixtures with aqueous ethanol containing 0.01% HCl first in an Amberlite XAD-7HP column (ethanol/H2O=35:65) and then in a Sephadex LH-20 column (ethanol/H2O=25:75). Crude anthocyanin extracts were isolated using the Amberlite column, and a purity of 32% was obtained based on UV-vis analysis. Three fractions of anthocyanin mixtures were isolated from the crude extracts using the Sephadex column with purities ranging from 59% to 68%. Three pure monomeric anthocyanins of malvidin-3-O-glucoside, petunidin-3-O-glucoside, and delphinidin-3-O-glucoside were also isolated by semi-preparative HPLC and identified by HPLC-DAD-ESI-MS/MS. The purities of these anthocyanins were determined by analytical HPLC and estimated to be 97.7%, 99.3%, and 95.4%, respectively. The results of this study may help promote the purification of anthocyanins from most blueberry varieties as well as from other plant materials.

    Full Text Available "nAmber suppressor tRNA is a mutant allele coding for a tRNA, whose anticodon is altered in such a way that the suppressor tRNA inserts an amino acid at an amber codon in translation which leads to suppressing (preventing termination. And some Amber suppressor tRNA strains were found. We propose that gold nanoparticles combined with highly expressed amber suppressor tRNA which can be uptake by cells and recognized by AARS (aminoacyl tRNA synthetase will lead to the formation of C-terminally extended proteins. These proteins probably will not work properly, leading bacteria's death. Because of the difference of tRNA between prokaryotic and eukaryotic cells, even between different bacteria species, this amber suppressor tRNA is orthogonal for other species and cannot be recognized by AARS, therefore has no toxicity to other species. May it be an excellent antibacterial agent in the future? In this article we provide a screening method for the highly expressed amber suppressor tRNA using randomly bases mutation, radioactive selection, activity test in vivo, and finally linkage of the amber suppressor tRNA to gold nanoparticles.

    2014-01-01

    The Impact-Parameter dependent Color Glass Condensate (b-CGC) and Saturation (IP-Sat) dipole models incorporate key features of small-x physics properties and match smoothly to the perturbative QCD regime at large $Q^2$ for a given $x$. Although both models include saturation effects and depend on impact-parameter, the former is based on the non-linear BK equation, while the latter is based on DGLAP evolution. After confronting the models to the recently released high precision combined HERA data, we show that in both models, the typical impact-parameter probed in the total $\\gamma^{*}p$ cross-section is about $b\\approx 2\\div 3\\,\\text{GeV}^{-1}$ and the proton saturation scale is $Q_S<1$ GeV in HERA kinematics. We show that most features of inclusive DIS and exclusive diffractive data at HERA are correctly reproduced in both models. Nevertheless, the b-CGC and the IP-Sat models give significantly different predictions beyond the current HERA kinematics for the structure functions at very low x and high vir...

    Desert ants feeding on dead arthropods forage for food items that are distributed unpredictably in space and time in the food-scarce terrain of the Saharan salt pans [1]. Scavengers of the genus Cataglyphis forage individually and do not lay pheromone trails [2]. They rely primarily on path integration [3] for navigation and, in addition, use visual [4] and olfactory cues [5-7]. While most studies have focused on the navigational mechanisms of ants targeting a familiar place like the nest or a learned feeding site, little is known about how ants locate food in their natural environment. Here we show that Cataglyphis fortis is highly sensitive to and attracted by food odors, especially the necromone linoleic acid, enabling them to locate tiny arthropods over several meters in distance. Furthermore, during the search for food, ants use extensive crosswind walks that increase the chances of localizing food plumes. By combining high sensitivity toward food odors with crosswind runs, the ants efficiently screen the desert for food and hence reduce the time spent foraging in their harsh desert environment.

  20. A combined method for high-speed rail seismic monitoring and early warning

    Full Text Available The ground motion characteristics include the strength, frequency spectrum and duration time. In China, the PGA (peak ground acceleration is commonly used in determination of whether an earthquake warning is necessary when the high-speed train is on the rail. This method has not given an earthquake early warning time, and it only considers the strength factor of an earthquake, so the system may release an alarm for the near and small earthquakes which are no destructive. The new alarm method reconciles the timeliness and stability. It issues a P wave warning when the system receives seismic wave first, which will make the train to decelerate. Then, the system will confirm whether the P wave alarm is correct using the joint alarm result of CAV (cumulative absolute velocity and PGA, and then take measures according to the result. The new method eliminates the interference from the near and small earthquakes, as well as the large and far earthquakes, and ensures the safety of the train when it is subjected to earthquakes. In this paper, we use seismic data to simulate the combined alarm of CAV and PGA, and then obtain the cumulative time of CAV and the time interval between CAV and PGA. Finally, we compare the new method with the double-station, earthquake monitoring alarm method which is currently used on China's high-speed rail, and find the new alarm method is better in the aspect of alarm timeliness.

    Biology and medicine sample measurement takes an important role in the microscopic optical technology. Optical tweezer has the advantage of accurate capture and non-pollution of the sample. The SPR(surface plasmon resonance) sensor has so many advantages include high sensitivity, fast measurement, less consumption of sample and label-free detection of biological sample that the SPR sensing technique has been used for surface topography, analysis of biochemical and immune, drug screening and environmental monitoring. If they combine, they will play an important role in the biological, chemical and other subjects. The system we propose use the multi-axis cage system, by using the methods of reflection and transmiss ion to improve the space utilization. The SPR system and optical tweezer were builtup and combined in one system. The cage of multi-axis system gives full play to its accuracy, simplicity and flexibility. The size of the system is 20 * 15 * 40 cm3 and thus the sample can be replaced to switch between the optical tweezers system and the SPR system in the small space. It means that we get the refractive index of the sample and control the particle in the same system. In order to control the revolving stage, get the picture and achieve the data stored automatically, we write a LabVIEW procedure. Then according to the data from the back focal plane calculate the refractive index of the sample. By changing the slide we can trap the particle as optical tweezer, which makes us measurement and trap the sample at the same time.

    Among the climate disasters, drought is one of the most difficult to characterise because of its complex nature and variety of impacts. These issues can be reflected in possible biases when drought indicators are projected to the future. Many studies are based on indicators independently computed and then compared; though this approach is powerful, the conclusions might vary according to each indicator, thus possibly resulting in contradicting findings. In this study, we focus on the frequency, duration, intensity, and severity of meteorological drought events in Europe and their projection until the end of this century, using a single indicator derived from the rational weighting of the Standardized Precipitation Index (SPI), the Standardized Precipitation-Evapotranspiration Index (SPEI), and the Reconnaissance Drought Indicator (RDI). The combination of the different indicators is based on the predominance of the drought signal, thus avoiding possible contradictory results. Future droughts have been studied for the periods 2041 to 2070 and 2071 to 2100, using an ensemble of the EURO-CORDEX high-resolution (0.11°) models that were bias-adjusted using the E-OBS observational dataset. Results show that meteorological drought events tend to be longer, more frequent and severe in southern Europe, especially in the period from 2071 to 2100 under the RCP8.5 scenario, while under the RCP4.5 scenario smaller but still significant drying trends are predicted. Both RCP4.5 and RCP8.5 project a wetting tendency for Northern and Central Europe, though in 2041-2070 individual model results can be contradictory for Central Europe. The combined indicator, which incorporates precipitation as well as minimum and maximum temperature, therefore, helps understanding future European drought patterns at regional level especially in climate change transition areas as Central and Eastern Europe.

    NASA is currently carrying out science and technical studies to identify its next astronomy flagship mission, slated to begin development in the 2020s. It has become clear that a Large Ultraviolet/Optical/IR (LUVOIR) Surveyor mission (dprimary ≍ 12 m, Δλ ≍ 1000 Å - 2 μm spectroscopic bandpass) can carry out the largest number of NASA's exoplanet and astrophysics science goals over the coming decades. The science grasp of a LUVOIR Surveyor is broad, ranging from the direct detection of potential biomarkers on rocky planets to the flow of matter into and out of galaxies and the history of star-formation across cosmic time. There are technical challenges for several aspects of the LUVOIR Surveyor concept, including component level technology readiness maturation and science instrument concepts for a broadly capable ultraviolet spectrograph. We present the scientific motivation for, and a preliminary design of, a multiplexed ultraviolet spectrograph to support both the exoplanet and astrophysics goals of the LUVOIR Surveyor mission concept, the Combined High-resolution and Imaging Spectrograph for the LUVOIR Surveyor (CHISL). CHISL includes a highresolution (R ≍ 120,000; 1000 - 1700Å) point-source spectroscopy channel and a medium resolution (R >= 14,000 from 1000 - 2000 Å in a single observation and R 24,000 - 35,000 in multiple grating settings) imaging spectroscopy channel. CHISL addresses topics ranging from characterizing the composition and structure of planet-forming disks to the feedback of matter between galaxies and the intergalactic medium. We present the CHISL concept, a small sample of representative science cases, and the primary technological hurdles. Technical challenges include high-efficiency ultraviolet coatings and high-quantum efficiency, large-format, photon counting detectors. We are actively engaged in laboratory and flight characterization efforts for all of these enabling technologies as components on sounding rocket payloads under

    Full Text Available Background. Nearly one-third of adults in India use tobacco, resulting in 1.2 million deaths. However, little is known about knowledge, attitudes, and practices (KAP related to smoking in the impoverished state of Uttarakhand. Methods. A cross-sectional epidemiological prevalence survey was undertaken. Multistage cluster sampling selected 20 villages and 50 households to survey from which 1853 people were interviewed. Tobacco prevalence and KAP were analyzed by income level, occupation, age, and sex. 95% confidence intervals were calculated using standard formulas and incorporating assumptions in relation to the clustering effect. Results. The overall prevalence of tobacco usage, defined using WHO criteria, was 38.9%. 93% of smokers and 86% of tobacco chewers were male. Prevalence of tobacco use, controlling for other factors, was associated with lower education, older age, and male sex. 97.6% of users and 98.1% of nonusers wanted less tobacco. Except for lung cancer (89% awareness, awareness of diseases caused by tobacco usage was low (cardiac: 67%; infertility: 32.5%; stroke: 40.5%. Conclusion. A dangerous combination of high tobacco usage prevalence, ignorance about its dangers, and few quit attempts being made suggests the need to develop effective and evidence based interventions to prevent a health and development disaster in Uttarakhand.

    BACKGROUND: In the process of early screening and interventions to high risk infants with brain damage,the occasion and choosing methods of interventions and the combined application of different interventions are still at the exploratory phase.OBJECTIVE: To observe the efficacy of early intervention using Vojta and Bobath combined treatment in high risk infants with brain damage, and investigate the effect of early rehabilitation on the prognosis.DESIGN: A randomized controlled comparative observation.SETTING: Daqing Oil Field General Hospital of Heilongjiang Province.PARTICIPANTS: Eighty-four high risk infants younger than 1 year were selected from the Department of Pediatrics, Daqing Oil Field General Hospital of Heilongjiang Province from October 2005 to October 2006,including 52 boys (62%) and 32 girls (38%). The treatment started at the age of 0 - 3 months in 11 cases (13%), 4 - 6 months in 28 cases (33%), 7 - 9 months in 35 cases (42%), and 10 - 12 months in 10 cases (12%). Infants with at least two of the followings were enrolled, including 7 Vojta abnormal postural reflexes,slow or disorder of motor development, increase of muscular tension, postural abnormality, primary reflection residual and CT/MRI abnormalities. Informed consents were obtained from their guardians. The 84 infants were randomly divided into treatment group (n =42) and control group (n =42).METHODS: All the children were intravenously injected with cerebroprotein hydrolysate injection or cattle encephalon glycoside and ignotin injection, 10 times as a course for 2 - 5 courses; Besides, the infants in the treatment group also received early rehabilitative training of Vojta and Bobath combined treatment, once a day, 40 minutes per time, 5 times a week followed by a 2-day rest, 1 month as a course, and totally 2 - 5 courses. The Vojta method was to facilitate the automatic regulation by reflexlocomotion. Bobath method was to inhibit abnormal posture but facilitate the normal one, thus it is

    Full Text Available Biotherapeutics are often produced in non-human host cells like Escherichia coli, yeast, and various mammalian cell lines. A major focus of any therapeutic protein purification process is to reduce host cell proteins to an acceptable low level. In this study, various E. coli host cell proteins were identified at different purifications steps by HPLC fractionation, SDS-PAGE analysis, and tryptic peptide mapping combined with online liquid chromatography mass spectrometry (LC-MS. However, no host cell proteins could be verified by direct LC-MS analysis of final drug substance material. In contrast, the application of affinity enrichment chromatography prior to comprehensive LC-MS was adequate to identify several low abundant host cell proteins at the final drug substance level. Bacterial alkaline phosphatase (BAP was identified as being the most abundant host cell protein at several purification steps. Thus, we firstly established two different assays for enzymatic and immunological BAP monitoring using the cobas® technology. By using this strategy we were able to demonstrate an almost complete removal of BAP enzymatic activity by the established therapeutic protein purification process. In summary, the impact of fermentation, purification, and formulation conditions on host cell protein removal and biological activity can be conducted by monitoring process-specific host cell proteins in a GMP-compatible and high-throughput (> 1000 samples/day manner.

    Full Text Available First of its kind combined atmospheric and ocean profile data were collected by the recently upgraded NASA Langley Research Center’s (LaRC High Spectral Resolution Lidar (HSRL-1 during the 17 July – 7 August 2014 Ship-Aircraft Bio-Optical Research Experiment (SABOR. This mission sampled over a region that covered the Gulf of Maine, open-ocean near Bermuda, and coastal waters from Virginia to Rhode Island. The HSRL-1 and the Research Scanning Polarimeter from NASA Goddard Institute for Space Studies collected data onboard the NASA LaRC King Air aircraft and flight operations were closely coordinated with the Research Vessel Endeavor that made in situ ocean optical measurements. The lidar measurements provided profiles of atmospheric backscatter and particulate depolarization at 532nm, 1064nm, and extinction (532nm from approximately 9km altitude. In addition, for the first time HSRL seawater backscatter, depolarization, and diffuse attenuation data at 532nm were collected and compared to both the ship measurements and the Moderate Resolution Imaging Spectrometer (NASA MODIS-Aqua satellite ocean retrievals.

    2017-08-01

    Radiative transport modelling can combine the effects of both large-scale (deterministic) and the small-scale (statistical) structure on the coda envelopes of high-frequency regional seismograms. We describe a computer code to implement radiative transport modelling that propagates packets of seismic body wave energy along ray paths through large-scale deterministic 3-D structure, including the effects of velocity gradients, intrinsic attenuation, source radiation pattern and multiple scattering by layer boundaries and small-scale heterogeneities specified by a heterogeneity spectrum. The spatial distribution of these energy packets can be displayed as time snapshots to aid in the understanding of regional phase propagation or displayed as a coda envelope by summing at receiver bins. These techniques are applied to earthquakes and explosions recorded in the Lop Nor, China region to model observed narrow band passed seismic codas in the 1-4 Hz band. We predict that source discriminants in this region based on P/Lg amplitude ratios will best separate earthquake and explosion populations at frequencies 2 Hz and higher.

    As an important biomarker and therapeutic target, telomerase has attracted considerable attention concerning its detection and monitoring. Here, we present a colorimetry and surface enhanced Raman scattering (SERS) dual-mode telomerase activity detection method, which has several distinctive advantages. First, colorimetric functionality allows rapid preliminary discrimination of telomerase activity by the naked eye. Second, the employment of SERS technique results in greatly improved detection sensitivity. Third, the combination of colorimetry and SERS into one detection system can ensure highly efficacious and sensitive screening of numerous samples. Besides, the avoidance of polymerase chain reaction (PCR) procedures further guarantees fine reliability and simplicity. Generally, the presented method is realized by an "elongate and capture" procedure. To be specific, gold nanoparticles modified with Raman molecules and telomeric repeat complementary oligonucleotide are employed as the colorimetric-SERS bifunctional reporting nanotag, while magnetic nanoparticles functionalized with telomerase substrate oligonucleotide are used as the capturing substrate. Telomerase can synthesize and elongate telomeric repeats onto the capturing substrate. The elongated telomeric repeats subsequently facilitate capturing of the reporting nanotag via hybridization between telomeric repeat and its complementary strand. The captured nanotags can cause a significant difference in the color and SERS intensity of the magnetically separated sediments. Thus both the color and SERS can be used as indicators of the telomerase activity. With fast screening ability and outstanding sensitivity, we anticipate that this method would greatly promote practical application of telomerase-based early-stage cancer diagnosis.

    This study reports on the attainment of optimal conditions for two electrolytic methods to treat wastewater: namely, electrocoagulation and particle destabilization of a highly polluted industrial wastewater, and electrochemically induced oxidation induced by in situ generation of Fenton's reactive. Additionally, a combined method that consisted of electrochemical treatment plus {gamma}-irradiation was carried out. A typical composition of the industrial effluent treated was COD 3400 mg/l, color 3750 Pt/Co units, and fecal coliforms 21000 MPN/ml. The best removal efficiency was obtained with electrochemical oxidation induced in situ, that resulted in the reduction of 78% for the COD, 86% color and 99.9% fecal coliforms removal. A treatment sequence was designed and carried out, such that after both electrochemical processes, a {gamma}-irradiation technique was used to complete the procedure. The samples were irradiated with various doses in an ALC {gamma}-cell unit provided with a Co-60 source. The removal efficiency obtained was 95% for the COD values, 90% color and 99.9% for fecal coliforms.

    With increasing demand for in-vivo observation of living cells, microscope techniques that do not need staining become more and more important. In this talk we present a combined multi-photon-acoustic microscope with the possibility to measure synchronously properties addressed by ultrasound and two-photon fluorescence. Ultrasound probes the local mechanical properties of a cell, while the high resolution image of the two-photon fluorescence delivers insight in cell morphology and activity. In the acoustic part of the microscope an ultrasound wave, with a frequency of GHz, is focused by an acoustic sapphire lens and detected by a piezo electric transducer assembled to the lens. The achieved lateral resolution is in the range of 1μm. Contrast in the images arises mainly from the local absorption of sound in the cells, related to properties, such as mass density, stiffness and viscose damping. Additionally acoustic microscopy can access the cell shape and the state of the cell membrane as it is a intrinsic volume scanning technique.The optical part bases on the emission of fluorescent biomolecules naturally present in cells (e.g. NAD(P)H, protophorphyrin IX, lipofuscin, melanin). The nonlinear effect of two-photon absorption provides a high lateral and axial resolution without the need of confocal detection. In addition, in the near-IR cell damages are drastically reduced in comparison to direct excitation in the visible or UV. Both methods can be considered as minimal invasive, as they relay on intrinsic contrast mechanisms and dispense with the need of staining. First results on living cells are presented and discussed.

    To evaluate the diagnosis significance of single high-frequency ultrasonography and mammography and combination therapy of both on breast cancer. 352 cases of female breast cancer patients were selected from The First Affiliated Hospital of Zhengzhou University from January 2012 to December 2014. Among the 352 patients, 124 patients had only performed high-frequency ultrasonography detection, 102 cases of patients were only conducted mammography, and 126 patients had applied the combination detection of high-frequency ultrasonography and mammography. The coincidence rate of single mammography detection was 79.4%, the misdiagnosis rate was 10.8%, and the missed diagnosis rate was 9.8%; the coincidence rate of single high frequency ultrasonography detection was 83.9%, the misdiagnosis rate was 11.5%, the missed diagnosis rate was 4.6%; the coincidence rate of combination of high frequency ultrasonography detection was 89.7%, the misdiagnosis rate was 6.3%, the missed diagnosis rate was 4.0%. The detection rate and missed diagnosis rate of combination diagnosis had statistical difference with single high frequency ultrasonography and single mammography. There was no statistical difference on misdiagnosis rate. mammography and high frequency ultrasonography respectively had their own advantages. The combination application of both had better diagnosis complementary, and could significantly improved the detection rate and accuracy rate on breast cancer, and decreased the misdiagnosis rate and missed diagnosis rate.

    Treatment with initial high-dose prednisolone and a combination of methotrexate (MTX) and sulfasalazine (SSZ) according to the COBRA regimen (Dutch acronym for combinatietherapie bij reumatoide artritis, 'combination therapy for rheumatoid arthritis'), has repeatedly been demonstrated to be very effective in early rheumatoid arthritis (RA). COBRA combination therapy is superior to initial monotherapy of SSZ and MTX, is also associated with a good long-term outcome, is as safe as other treatment regimes, and performs as well as the combination of high-dose MTX and the tumor necrosis factor antagonist infliximab. A pilot study with an intensified version of the COBRA combination therapy showed that strict monitoring and aggressive treatment intensification based on the Disease Activity Score can result in a remission rate of 90% in patients with active early RA. Also, the first results indicate that an attenuated variation on COBRA combination therapy, called 'COBRA-light', is effective in decreasing disease activity and is generally well tolerated. Based on these results, we conclude that initial high-dose prednisolone in combination with MTX and SSZ could or should be the first choice in early active RA since it is effective and safe, and the cost price of the drugs is low.

    作为宪政的一个特例,公民不服从在稳定宪政制度方面的作用不容忽视。缘于公民不服从概念本身的模糊性,人们常或将公民不服从和与之有密切关系的良知拒绝相等同,或将二者完全割裂开来。从二者的思想源泉与概念解析出发,我们可得出二者之间的关系并非是非此即彼,而是同一概念的两个不同侧面。%As a special case of the constitutional government, the great role of Civil Disobedience in maintaining the stability of the Constitutional government system should not be neglected. Because of its illegibility, people either equate Civil Disobedience with Conscientious Refusal or break Civil Disobedience away from Conscientious Refusal. Actually, it is not an either - or question, instead, on their source of idea and the analysis of concept, Civil Disobedience and Conscientious Refusal represent different aspects of one and the same concept.

    2011-01-01

    Full Text Available Breakthrough in treatment of Alzheimer's disease with a shift from irrational dangerous chelation therapy to rational safe evidence based oral zinc therapy. Evidence based medicine: After synthesizing the best available clinical evidence I conclude that oral zinc therapy is a conscientious choice for treatment of free copper toxicosis in individual patients with Alzheimer's disease. Hypothesis 1: Age related free copper toxicosis is a causal factor in pathogenesis of Alzheimer's disease. There are 2 neurodegenerative diseases with abnormalities in copper metabolism: (a the juvenile form with degeneration in the basal ganglia (Wilson's disease and (b the age related form with cortical neurodegeneration (Alzheimer's disease. Initially the hypothesis has been that neurodegeneration was caused by accumulation of copper in the brain but later experiences with treatment of Wilson's disease led to the conviction that free plasma copper is the toxic form of copper: it catalyzes amyloid formation thereby generating oxidative stress, free radicals and degeneration of cortical neurons. Hypothesis 2: Oral zinc therapy is an effective and safe treatment of free copper toxicosis in Alzheimer's disease. Proposed dosage: 50 mg elementary zinc/day. Warning: Chelation therapy is irrational and dangerous in treatment of copper toxicosis in Alzheimer's disease.

    Through literature review, the article points out that the existing of the high-efficiency agriculture definition is limited to results oriented thinking, apparently lack of process oriented thinking. Combined with the connotation of fusion agriculture and tourism, respectively from the time and space utilization efficiency, cash cost, elements of input and output form, etc, gives high-efficiency agriculture a new connotation. Under the perspective of a combined agriculture with tourism, efficient use of time and space, low realized cost, less costs and output form of agriculture, this is highly effective agriculture.

    The climatological behaviour of the thermospheric meridional wind above Kiruna, Sweden (67.4 N, 20.4 E) has been investigated for seasonal and solar cycle dependence using six different techniques, comprising both model and experimental sources. Model output from both the empirical Horizontal Wind Model (HWM) (Hedin et al., 1988) and the numerical coupled thermosphere and ionosphere model (CTIM) are compared to the measured behaviour at kiruna, as a single site example. The empirical International Reference Ionosphere (IRI) model is used as input to an implementation of servo theory, to provide another climatology combining empirical input with a theoretical framework. The experimental techniques have been introduced in a companion paper in this issue and provide climatologies from direct measurements, using fabry-perot interferometers (FPI), together with 2 separate techniques applied to the European incoherent scatter radar (EISCAT) database to derive neutral winds. One of these techniques uses the same implementation of servo theory as has been used with the IRI model. Detailed comparisons for each season and solar activity category allow for conclusions to be drawn as to the major influences on the climatological behaviour of the wind at this latitude. Comparison of the incoherent scatter radar (ISR) derived neutral winds with FPI, empirical model and numerical model winds is important to our understanding and judgement of the validity of the techniques used to derive thermospheric wind databases. The comparisons also test model performance and indicate possible reasons for differences found between the models. In turn, the conclusions point to possible improvements in their formulation. In particular it is found that the empirical models are over-reliant on mid-latitude data in their formulation, and fail to provide accurate estimates of the winds at high-latitudes. (orig.)

    In this work a new generation of bioceramic personalized implants were developed. This technique combines the processes of solid freeform fabrication (SFF) and combustion synthesis (CS) to create personalized bioceramic implants with tricalcium phosphate (TCP) and hydroxyapatite (HA). These porous bioceramics will be used to fill the tibial bone gap created by the opening wedge high tibial osteotomy (OWHTO). A freeform fabrication with three-dimensional printing (3DP) technique was used to fabricate a metallic mold with the same shape required to fill the gap in the opening wedge osteotomy. The mold was subsequently used in a CS process to fabricate the personalized ceramic implants with TCP and HA compositions. The mold geometry was designed on commercial 3D CAD software. The final personalized bioceramic implant was produced using a CS process. This technique was chosen because it exploits the exothermic reaction between P₂O₅ and CaO. Also, chemical composition and distribution of pores in the implant could be controlled. To determine the chemical composition, the microstructure, and the mechanical properties of the implant, cylindrical shapes were also fabricated using different fabrication parameters. Chemical composition was performed by X-ray diffraction. Pore size and pore interconnectivity was measured and analyzed using an electronic microscope system. Mechanical properties were determined by a mechanical testing system. The porous TCP and HA obtained have an open porous structure with an average 400 µm channel size. The mechanical behavior shows great stiffness and higher load to failure for both ceramics. Finally, this personalized ceramic implant facilitated the regeneration of new bone in the gap created by OWHTO and provides additional strength to allow accelerated rehabilitation.

    A combined mesophilic anaerobic-thermophilic aerobic process was used to treat high-strength food wastewater in this study. During the experimental period, most of solid residue from the mesophilic anaerobic reactor (R1) was separated by centrifugation and introduced into the thermophilic aerobic...... reactor (R2) for further digestion. Then, thermophilic aerobically-digested sludge was reintroduced into R1 to enhance reactor performance. The combined process was operated with two different Runs: Run I with hydraulic retention time (HRT)=40d (corresponding OLR=3.5kgCOD/m3 d) and Run II with HRT=20d...... (corresponding OLR=7kgCOD/m3). For a comparison, a single-stage mesophilic anaerobic reactor (R3) was operated concurrently with same OLRs and HRTs as the combined process. During the overall digestion, all reactors showed high stability without pH control. The combined process demonstrated significantly higher...

    2004-09-01

    Full Text Available Field-aligned currents convey stress between the magnetosphere and ionosphere, and the associated low altitude magnetic and electric fields reflect the flow of electromagnetic energy to the polar ionosphere. We introduce a new technique to measure the global distribution of high latitude Poynting flux, S||, by combining electric field estimates from the Super Dual Auroral Radar Network (SuperDARN with magnetic perturbations derived using magnetometer data from the Iridium satellite constellation. Spherical harmonic methods are used to merge the data sets and calculate S|| for any magnetic local time (MLT from the pole to 60° magnetic latitude (MLAT. The effective spatial resolutions are 2° MLAT, 2h MLT, and the time resolution is about one hour due to the telemetry rate of the Iridium magnetometer data. The technique allows for the assessment of high-latitude net S|| and its spatial distribution on one hour time scales with two key advantages: (1 it yields the net S|| including the contribution of neutral winds; and (2 the results are obtained without recourse to estimates of ionosphere conductivity. We present two examples, 23 November 1999, 14:00-15:00 UT, and 11 March 2000, 16:00-17:00 UT, to test the accuracy of the technique and to illustrate the distributions of S|| that it gives. Comparisons with in-situ S|| estimates from DMSP satellites show agreement to a few mW/m2 and in the locations of S|| enhancements to within the technique's resolution. The total electromagnetic energy flux was 50GW for these events. At auroral latitudes, S|| tends to maximize in the morning and afternoon in regions less than 5° in MLAT by two hours in MLT having S||=10 to 20mW/m2 and total power up to 10GW. The power poleward of the Region 1 currents is about one

    Degradation of methylene blue (MB) was performed using the pulsed discharge process (PDP) combined with spent tea leaves (STLs). The effects of STL dosage, concentration of initial solution, and pH were analyzed in the combined treatment. Results showed that the combined treatment was effective for dye wastewater degradation; when the dosage of STLs was 3.2 g/L, the degradation efficiency reached 90% after 15 min treatment, and STLs showed a good repeatability. The degradation rate decreased with increasing initial MB concentration but not related to the solution pH in the combined treatment. Fourier-transform infrared spectra and N2 adsorption suggested that the number of acidic and basic groups in the STL surface increased after the treatment, but the surface area and pore volume remained unchanged.

    Locally advanced prostate cancer entails a risk of local,regional and systemic relapse requiring the combination of a Ioco-regional treatment,namely external beam radiotherapy(EBRT) to control the pelvic-confined disease,combined with a systemic therapy,namely androgen-deprivation therapy(ADT),to potentiate irradiation and to destroy the infra-clinical androgen-dependant disease outside the irradiated volume.Many phases Ⅲ randomized trials have paved the way in establishing the indications of this combined approach,which requires a long term ADT(≥2 years) with LHRH agonists.The duration of ADT may be reduced to 6 months should there be a significant comorbidity,a reluctance from the patient or a poor tolerance.A multidisciplinary approach will enable physicians to tailor the treatment strategy and a close cooperation between the specialists and the general practitioners will be set up to prevent as much as possible the side-effects of ADT.

    This case report describes the effect of a combination of high-pull headgear and Class III elastics on the nonsurgical treatment of an adult open bite. The 19-year 1-month-old Japanese female presented with the anterior open bite of 4.0 mm and mild crowding. She had a skeletal Class II but a Class III molar relationship due to a severe proclination of the mandibular dental arch. Unilateral congenital missing premolars caused a discrepancy between the facial and dental midline. After extraction of two premolars and the impacted mandibular third molars, nonsurgical therapy was performed using the standard edgewise appliance combined with a high-pull headgear and Class III elastics. The successful treatment outcome and stability of the final occlusion indicates that a combination of high-pull headgear and Class III elastics is one of the effective devices in the nonsurgical treatment of open bite and, is especially helpful in uprighting the mandibular dental arch.

    The C370 Program was awarded in October 2010 with the ambitious goal of designing and testing the most electrically efficient recuperated microturbine engine at a rated power of less than 500 kW. The aggressive targets for electrical efficiency, emission regulatory compliance, and the estimated price point make the system state-of-the-art for microturbine engine systems. These goals will be met by designing a two stage microturbine engine identified as the low pressure spool and high pressure spool that are based on derivative hardware of Capstone’s current commercially available engines. The development and testing of the engine occurred in two phases. Phase I focused on developing a higher power and more efficient engine, that would become the low pressure spool which is based on Capstone’s C200 (200kW) engine architecture. Phase II integrated the low pressure spool created in Phase I with the high pressure spool, which is based on Capstone’s C65 (65 kW) commercially available engine. Integration of the engines, based on preliminary research, would allow the dual spool engine to provide electrical power in excess of 370 kW, with electrical efficiency approaching 42%. If both of these targets were met coupled with the overall CHP target of 85% total combined heating and electrical efficiency California Air Resources Board (CARB) level emissions, and a price target of $600 per kW, the system would represent a step change in the currently available commercial generation technology. Phase I of the C370 program required the development of the C370 low pressure spool. The goal was to increase the C200 engine power by a minimum of 25% — 250 kW — and efficiency from 32% to 37%. These increases in the C200 engine output were imperative to meet the power requirements of the engine when both spools were integrated. An additional benefit of designing and testing the C370 low pressure spool was the possibility of developing a stand-alone product for possible

    The type of ultrasound transducer used influences the quality of a reconstructed ultrasound image. This study analyzed the effect of transducer type on ultrasound computed tomography (UCT) image quality. The UCT was modeled in an ultrasound simulator by using a 5 cm anatomy model and a ring-shape 5 MHz 128 transducer array, which considered attenuation, refraction, and reflection. Speed-of-sound images were reconstructed by the Radon transform as the UCT image modality. Acoustic impedance images were also reconstructed by the delayand-sum (DAS) method, which considered the speed of sound information. To determine the optimal combination of transducers in observation, point-source, flat, and focused transducers were tested in combination as trasmitters and receivers; UCT images were constructed from each combination. The combination of point-source/flat transducer as transmitting and receiving devices presented the best reconstructed image quality. In UCT implementation, the combination of a flat transducer for transmitting and a point transducer for receiving permitted acceptable image quality.

    The goal of this research has been to improve measurements of snowfall using a combination of millimeter-wavelength radar and High Spectral Resolution Lidar (HSRL) Observations. Snowflakes are large compared to the 532nm HSRL wavelength and small compared to the 3.2 and 8.6 mm wavelength radars used in this study. This places the particles in the optical scattering regime of the HSRL, where extinction cross-section is proportional to the projected area of the particles, and in the Rayleigh regime for the radar, where the backscatter cross-section is proportional to the mass-squared of the particles. Forming a ratio of the radar measured cross-section to the HSRL measured cross section eliminates any dependence on the number of scattering particles, yielding a quantity proportional to the average mass-squared of the snowflakes over the average area of the flakes. Using simultaneous radar measurements of particle fall velocities, which are dependent particle mass and cross-sectional area it is possible to derive the average mass of the snow flakes, and with the radar measured fall velocities compute the snowfall rate. Since this retrieval requires the optical extinction cross-section we began by considering errors this quantity. The HSRL is particularly good at measuring the backscatter cross-section. In previous studies of snowfall in the high Arctic were able to estimate the extinction cross-section directly as a fixed ratio to the backscatter cross-section. Measurements acquired in the STORMVEX experiment in Colorado showed that this approach was not valid in mid-latitude snowfalls and that direct measurement of the extinction cross-section is required. Attempts to measure the extinction directly uncovered shortcomings in thermal regulation and mechanical stability of the newly deployed DOE HSRL systems. These problems were largely mitigated by modifications installed in both of the DOE systems. We also investigated other sources of error in the HSRL direct

    Elevated serum phosphorus is associated with higher death risk in hemodialysis patients. Previous studies have suggested that both higher serum parathyroid hormone (PTH) level and higher dietary protein intake may contribute to higher serum phosphorus levels. However, it is not well known how these two factors simultaneously contribute to the combined risk of hyperphosphatemia in real patient-care scenarios. We hypothesized that the likelihood of hyperphosphatemia increases across higher seru...

    Albanese, John; Montes, Ronald

    2011-11-01

    In this paper, we use bloodstains to illustrate an approach for identifying latent evidence on dark cloth using near infrared (NIR) photography combined with high dynamic range (HDR) photography techniques. NIR photography alone has been used to capture latent evidence that cannot be seen in normal ambient light. HDR techniques combine multiple bracketed photographs of the same image to increase the dynamic range of the photograph which can provide greater contrast. Using NIR photography alone, we were able to detect a bloodstain up to a 1/16 dilution, an improvement over previous studies. Combining NIR photography with the HDR process resulted in a noticeable increase in visibility up to 1/16 dilution when compared to NIR photographs alone. At 1/32 dilution, we were able to detect bloodstains that were not visible using NIR alone. NIR is a useful tool for imaging latent evidence, and combining NIR with HDR consistently provides better results over NIR alone.

  5. Is Conscientiousness negatively correlated with intelligence test and inspection time performance

    OpenAIRE

    2006-01-01

    The purpose of this study was to ascertain if high C developed as a compensation mechanism to make up for a lack of intelligence: our hypothesis was that C would negatively correlate with intelligence tests’ scores and IT accuracy scores. C was measured along with the other Big 5 factors via a 100 item personality questionnaire: there were 10 items for each factor, except C which had 10 items measuring each of its 6 subfacets, hence 100 items. Intelligence was measured via Rave...

    We demonstrate a compact, inexpensive, and reliable fiber-coupled light source with broad bandwidth and sufficient power at 1300 nm for high resolution optical coherence tomography (OCT) imaging in real-time applications. By combining four superluminescent diodes (SLEDs) with different central wavelengths, the light source has a bandwidth of 145 nm centered at 1325 nm with over 10 mW of power. OCT images of an excised stage 30 embryonic chick heart acquired with our combined SLED light source (<5 μm axial resolution in tissue) are compared with images obtained with a single SLED source (~10 μm axial resolution in tissue). The high resolution OCT system with the combined SLED light source provides better image quality (smaller speckle noise) and a greater ability to observe fine structures in the embryonic heart.

    To evaluate the incremental value of diffusion-weighted imaging (DWI) in combination with T2-weighted imaging to detect low (Gleason score, {<=} 6) and intermediate or high risk (Gleason score, {>=} 7) prostate cancer. Fifty-one patients who underwent MRI before prostatectomy were evaluated. Two readers independently scored the probability of tumour in eight regions of prostate on T2-weighted images (T2WI) and T2WI combined with apparent diffusion coefficient (ADC) maps. Data were divided into two groups - low risk and intermediate or high risk prostate cancer - and correlated with histopathological results. Diagnostic performance parameters, areas under the receiver-operating characteristic curve (AUCs) and interreader agreement were calculated. For both readers, AUCs of combined T2WI and ADC maps were greater than those of T2WI in intermediate or high risk (reader 1, 0.887 vs. 0.859; reader 2, 0.732 vs 0.662, P < 0.05) prostate cancers, but not in low risk (reader 1, 0.719 vs 0.725; reader 2, 0.685 vs. 0.680, P > 0.05) prostate cancers. Weighted {kappa} value of combined T2WI and ADC maps was 0.689. The addition of DWI to T2-weighted imaging improves the accuracy of detecting intermediate or high risk prostate cancers, but not for low risk prostate cancer detection. (orig.)

    Full Text Available This study presents a new steady-state visual evoked potential (SSVEP paradigm for brain computer interface (BCI systems. The new paradigm is High-Frequency Combination Coding-Based SSVEP (HFCC-SSVEP. The goal of this study is to increase the number of targets using fewer stimulation frequencies, with diminishing subject’s fatigue and reducing the risk of photosensitive epileptic seizures. This paper investigated the HFCC-SSVEP high-frequency response (beyond 25 Hz for 3 frequencies (25 Hz, 33.33 Hz, and 40 Hz. HFCC-SSVEP produces nn with n high stimulation frequencies through Time Series Combination Code. Furthermore, The Improved Hilbert-Huang Transform (IHHT is adopted to extract time-frequency feature of the proposed SSVEP response. Lastly, the differentiation combination (DC method is proposed to select the combination coding sequence in order to increase the recognition rate; as a result, IHHT algorithm and DC method for the proposed SSVEP paradigm in this study increase recognition efficiency so as to improve ITR and increase the stability of the BCI system. Furthermore, SSVEPs evoked by high-frequency stimuli (beyond 25 Hz minimally diminish subject’s fatigue and prevent safety hazards linked to photo-induced epileptic seizures. This study tests five subjects in order to verify the feasibility of the proposed method.

    Compulsory vaccination has contributed to the success of immunisation programmes in the USA and Australia, yet the benefits from compulsory vaccination are not universally recognised. Some people--experts and the public alike--believe that the benefits of compulsory vaccination are outweighed by the associated ethical problems. A review of vaccination legislation in the UK, Australia, and the USA raises four main points. First, compulsory vaccination may be effective in preventing disease outbreaks, reaching and sustaining high immunisation coverage rates, and expediting the introduction of new vaccines. Second, to be effective, compulsory programmes must have a reliable supply of safe and effective vaccines and most people must be willing to be vaccinated. Third, allowance of exemptions to compulsory vaccination may limit public backlash. Finally, compulsory vaccination may increase the burden on governments to ensure the safety of vaccines. Nevertheless, although compulsory immunisation can be very effective, it might not be acceptable in some countries where high coverage has been achieved through other approaches or efforts, such as in Sweden, Norway, Denmark, the Netherlands, and the UK. These factors should be considered when compulsory vaccinations are being introduced or immunisation laws refined. Lessons learned from compulsory vaccination could be useful to other public-health programmes.

    This article explores performance study for optical combinational designs based on nonlinear characteristics with semiconductor optical amplifier (SOA). Two configurations for optical half-adder with non-return-to-zero modulation pattern altogether with Mach-Zehnder modulator, interferometer at 50-Gbps data rate have been successfully realized. Accordingly, SUM and CARRY outputs have been concurrently executed and verified for their output waveforms. Numerical simulations for variation of data rate and key design parameters have been effectively executed outcome with optimum performance. Investigations depict overall good performance of the design in terms of the extinction factor. It also inferred that all-optical realization based on SOA is competent scheme, as it circumvents costly optoelectronic translation. This could be well supportive to erect larger complex optical combinational circuits.

    To understand how function arises from the interactions between neurons, it is necessary to use methods that allow the monitoring of brain activity at the single-neuron, single-spike level and the targeted manipulation of the diverse neuron types selectively in a closed-loop manner. Large-scale recordings of neuronal spiking combined with optogenetic perturbation of identified individual neurons has emerged as a suitable method for such tasks in behaving animals. To fully exploit the potential power of these methods, multiple steps of technical innovation are needed. We highlight the current state of the art in electrophysiological recording methods, combined with optogenetics, and discuss directions for progress. In addition, we point to areas where rapid development is in progress and discuss topics where near-term improvements are possible and needed.

    The concept of combined sensible/latent heat thermal energy storage (TES) has been exploited to mitigate an intrinsic thermocline TES systems drawback of heat transfer fluid outflow temperature reduction during discharging. In this study, the combined sensible/latent TES prototype under investigation is constituted by a packed bed of rocks and a small amount of encapsulated phase change material (AlSi12) as sensible heat and latent heat sections respectively. The thermo-fluid dynamics behavior of the combined TES prototype was analyzed by means of a computational fluid dynamics approach. Due to the small value of the characteristic vessel-to-particles diameter ratio, the effect of radial void-fraction variation, also known as channeling, was accounted for. Both the sensible and the latent heat sections of the storage were modeled as porous media under the assumption of local thermal non-equilibrium (LTNE). The commercial code ANSYS Fluent 15.0 was used to solve the model's constitutive conservation and transport equations obtaining a fairly good agreement with reference experimental measurements.

    The non-thermal technologies High Intensity Light Pulses (HILP) and Thermosonication (TS) were applied alone and in combination to study their effect on Escherichia coli inactivation in orange juice. Two different energy settings were chosen in the current study, 'Low' (L) and 'High' (H), being the combinations applied: HILP(L) (4.03 J/cm(2)), HILP(H) (5.1 J/cm(2)), TS(L) (2.8 min residence time at 40 °C) and TS(H) (5 min residence time at 50 °C). Both the individual technologies and their combinations (HILP&TS and TS&HILP) were studied. Results showed inactivation ranging from 1.10 (TS(H)) to 2.42 (HILP(H)) log cfu/ml for the hurdles when applied individually and from 2.5 (HILP(L)&TS(H)) to 3.93 (HILP(H)&TS(L)) log cfu/ml for the combined treatments. Similar reductions in E. coli populations were achieved in orange juice by all treatment combinations irrespective of the sequence in which they were applied. Copyright © 2011 Elsevier Ltd.

    We present a novel multiple laser beam scanning projection module using compact red-green-blue (RGB) fiber pigtailed laser modules for use in a high resolution pico-projector display system using a fiber bundle combiner in combination with a single MEMS mirror. This system can be used to create accurate multiple-projection images on a screen without overlaps or spaces among the projection images. The system uses very simple projection optics and has the potential to become a light engine unit for use in multiple projection systems, particularly those for light field displays. As such, light field display applications are also discussed.

    The nonperturbative regime of electron-positron pair creation by a relativistic proton beam colliding with a highly intense bichromatic laser field is studied. The laser wave is composed of a strong low-frequency and a weak high-frequency mode, with mutually orthogonal polarization vectors. We show that the presence of the high-frequency field component can strongly enhance the pair-creation rate. Besides, a characteristic influence of the high-frequency mode on the angular and energy distributions of the created particles is demonstrated, both in the nuclear rest frame and the laboratory frame.

    SUMMARY Context Cyanide poisoning is a major contributor to death in smoke inhalation victims and accidental exposure to cyanide occurs in a variety of industries. Moreover, cyanide has the potential to be used by terrorists, particularly in a closed space such as an airport or train station. Current therapies for cyanide poisoning must be given by intravenous administration, limiting their use in treating mass casualties. Objective We are developing two new cyanide antidotes—cobinamide, a vitamin B12 analog, and sulfanegen, a 3-mercaptopyruvate prodrug. Both drugs can be given by intramuscular administration, and therefore could be used to treat a large number of people quickly. We now asked if the two drugs would have an augmented effect when combined. Materials and Methods We used a non-lethal and two different lethal models of cyanide poisoning in mice. The non-lethal model assesses neurologic recovery by quantitatively evaluating the innate righting reflex time of a mouse. The two lethal models are a cyanide injection and a cyanide inhalation model. Results We found that the two drugs are at least additive when used together in both the non-lethal and lethal models: at doses where all animals died with either drug alone, the combination yielded 80 and 40% survival in the injection and inhalation models, respectively. Similarly, drug doses that yielded 40% survival with either drug alone yielded 80 and 100% survival in the injection and inhalatiion models, respectively. As part of the inhalation model, we developed a new paradigm in which animals are exposed to cyanide gas, injected intramuscularly with antidote, and then re-exposed to cyanide gas. This simulates cyanide exposure of a large number of people in a closed space, because people would remain exposed to cyanide, even after receiving an antidote. Conclusion The combination of cobinamide and sulfanegen shows great promise as a new approach to treating cyanide poisoning. PMID:21740135

    A new recycling hydrolytic-aerobic combined process was developed to treat the high concentration organic wastewater. Simulated wastewater containing 10 g·L-1 starch with a CODcr value of 10000 mg·L-1 wasused. At first, the hydrolytic degradation and aerobic degradation process were examined in two batch reactors, respectively. In the stand-alone hydrolytic process, starch in the wastewater almost disappeared after 11 h treatment, but CODCr remained as high as 5803mg·L-1 after two days. In the aerobic process, the biodegradation rate of starch was much slower during the first 11 h than that in the hydrolytic process, although the CODCr removal efficiency reached 89.6% and more than 90% starch could be degraded after 37.5 h. To determine the interaction effects of the two processes, a series of hydrolytic-aerobic combinations were examined in details. Hydrolytic process played an important role in the whole recycle combination process as it could improve the biodegradability of the high concentration starch wastewater. However, from the other experiments, the negative effect of hydrolytic acidification was found in the hydrolytic-aerobic combination, which suggested that the aerobic microorganisms needed time to adapt themselves to the acidic environment. The effect of the degrading time, which was spent in the hydrolytic and aerobic unit, and the number of circulations, with which the wastewater went through the two units were investigated. It was found that a recycle combination of 6 h hydrolytic process with 12 h aerobic process was highly effective and potentially economical, in which the final removal efficiency of CODcr and efficiency of starch degradation reached 94.1% and 98.8%, respectively.

    A combined mesophilic anaerobic-thermophilic aerobic process was used to treat high-strength food wastewater in this study. During the experimental period, most of solid residue from the mesophilic anaerobic reactor (R1) was separated by centrifugation and introduced into the thermophilic aerobic reactor (R2) for further digestion. Then, thermophilic aerobically-digested sludge was reintroduced into R1 to enhance reactor performance. The combined process was operated with two different Runs: Run I with hydraulic retention time (HRT) = 40 d (corresponding OLR = 3.5 kg COD/m(3) d) and Run II with HRT = 20 d (corresponding OLR = 7 kg COD/m(3)). For a comparison, a single-stage mesophilic anaerobic reactor (R3) was operated concurrently with same OLRs and HRTs as the combined process. During the overall digestion, all reactors showed high stability without pH control. The combined process demonstrated significantly higher organic matter removal efficiencies (over 90%) of TS, VS and COD and methane production than did R3. Quantitative real-time PCR (qPCR) results indicated that higher populations of both bacteria and archaea were maintained in R1 than in R3. Pyrosequencing analysis revealed relatively high abundance of phylum Actinobacteria in both R1 and R2, and a predominance of phyla Synergistetes and Firmicutes in R3 during Run II. Furthermore, R1 and R2 shared genera (Prevotella, Aminobacterium, Geobacillus and Unclassified Actinobacteria), which suggests synergy between mesophilic anaerobic digestion and thermophilic aerobic digestion. For archaea, in R1 methanogenic archaea shifted from genus Methanosaeta to Methanosarcina, whereas genera Methanosaeta, Methanobacterium and Methanoculleus were predominant in R3. The results demonstrated dynamics of key microbial populations that were highly consistent with an enhanced reactor performance of the combined process.

    A simple, rapid, and effective assay based on ultrafiltration combined with high-performance liquid chromatography and high-speed countercurrent chromatography was developed for screening and purifying alcohol dehydrogenase inhibitors from Glycyrrhiza uralensis root extract. Experiments were carried out to optimize binding conditions including alcohol dehydrogenase concentration, incubation time, temperature, and pH. By comparing the chromatograms, three compounds were found possessing alcohol dehydrogenase binding activity in Glycyrrhiza uralensis root. Under the target-guidance of ultrafiltration combined with the high-performance liquid chromatography experiment, liquiritin (1), isoliquiritin (2), and liquiritigenin (3) were separated by high-speed countercurrent chromatography using ethyl acetate/methanol/water (5:1:4) as the solvent system. The alcohol dehydrogenase inhibitory activities of these three isolated compounds were assessed; compound 2 showed strongest inhibitory activity with an IC50 of 8.95 μM. The results of the present study indicated that the combinative method using ultrafiltration, high-performance liquid chromatography and high-speed countercurrent chromatography could be widely applied for the rapid screening and isolation of enzyme inhibitors from complex mixtures.

  6. A method of beam combination of high-power incoherent fiber laser

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Diffraction efficiency of grating plays an important role in output power of incoherent fiber laser beam combination.Through theoretic analysis and numerical simulations it has been proved that the diffraction efficiency would increase with the decrease of grating frequency and wavelength bandwidth. On the condition that the width of a fiber array is fixed at W=10 cm, an optimum grating frequency were numerically simulated as f=230 mm-1. Also an unequal interval method was proposed to improve the system efficiency of diffraction into 0.4293, which is higher than 0.3824 under the equal interval condition.

    A platform for diagnostic applications showing signal-to-noise ratios that by far surpass those of traditional bioanalytical test formats has been developed. It combines the properties of modified nanocrystalline diamond (NCD) surfaces and those of polyethylene oxide and polypropylene oxide based block copolymers for surface passivation and binder conjugation with a new class of synthetic binders for proteins. The NCD surfaces were fluorine-, hydrogen-, or oxygen-terminated prior to further biofunctionalization and the surface composition was characterized by X-ray photoelectron spectroscopy. In a proof of principle demonstration targeting the C-reactive protein, an ELISA carried out using an F-terminated diamond surface showed a signal-to-noise ratio of 3,900 which compares well to the signal-to-noise of 89 obtained in an antibody-based ELISA on a polystyrene microtiter plate, a standard test format used in most life science laboratories today. The increase in signal-to-noise ratio is to a large extent the result of extremely efficient passivation of the diamond surface. The results suggest that significant improvements can be obtained in standardized test formats using new materials in combination with new types of chemical coatings and receptor molecules.

If you downloaded the original PDF but are unable to access the revision, please contact SPIE Digital Library Customer Service for assistance. The purpose of wavelength-beam combining (WBC) is to improve the output power of a multi-wavelength laser system while maintaining the quality of the combined beam. This technique has been primarily proposed for industrial applications, such as metal cutting and soldering, which require optical peak power between kilowatts and megawatts. In order to replace the bulkier solid-state lasers, we propose to use the WBC technique for photoacoustic (PA) applications, where a multi-wavelength focused beam with optical peak power between hundreds of watts up to several kilowatts is necessary to penetrate deeply into biological tissues. In this work we present an analytical study about the coupling of light beams emitted by diode laser bars at 808 nm, 880 nm, 910 nm, 940 nm, and 980 nm into a .

    This study presents a novel cloud masking approach for high resolution remote sensing images in the context of land cover mapping. As an advantage to traditional methods, the approach does not rely on thermal bands and it is applicable to images from most high resolution earth observation remote sensing sensors. The methodology couples pixel-based seed identification and object-based region growing. The seed identification stage relies on pixel value comparison between high resolution images and cloud free composites at lower spatial resolution from almost simultaneously acquired dates. The methodology was tested taking SPOT4-HRVIR, SPOT5-HRG and IRS-LISS III as high resolution images and cloud free MODIS composites as reference images. The selected scenes included a wide range of cloud types and surface features. The resulting cloud masks were evaluated through visual comparison. They were also compared with ad-hoc independently generated cloud masks and with the automatic cloud cover assessment algorithm (ACCA). In general the results showed an agreement in detected clouds higher than 95% for clouds larger than 50 ha. The approach produced consistent results identifying and mapping clouds of different type and size over various land surfaces including natural vegetation, agriculture land, built-up areas, water bodies and snow.

    The combined use of a rhamnolipid biosurfactant produced by Pseudomonas aeruginosa and an enzyme pool produced by solid-state fermentation with Penicillium simplicissimum using babassu cake as culture medium in the anaerobic treatment of an effluent with a high fat content from a poultry processing plant was evaluated. Central composite rotatable design was used to evaluate the enzyme pool and biosurfactant concentrations and the treatment temperature of the effluent containing about 2400 mg oil and grease per liter. The combination that yielded the highest specific methane production was 0.19% (w/v) enzyme pool and 114 mg/L biosurfactant at 33 °C. It could therefore be concluded that the combined use of a rhamnolipid biosurfactant with an enzyme preparation obtained from solid-state fermentation may enhance methane production and enable the use of anaerobic technology in this sector, eliminating the need for physicochemical processes or the addition of costly commercial enzymes.

    The purpose of this study was to investigate the effect of combined high pressure and Lactobacillus casei cell extract (CE) on Escherichia coli O157 strains with variation in pressure resistance in broth and sausage. Pressure-resistant (O157:H7 and O157:H12) and -sensitive (O157-M1 and O157-M2) E. coli strains were used. Pressure treatment at 350 MPa for 20 min in broth caused 1.1-1.2 logs reduction in O157:H12 and O157:H7 and 4.1-5.5 logs reduction in the O157-M1 and O157-M2. When high pressure was treated in the presence of CE (32 CEAU/mL), the combination treatment caused a significant inactivation in the pressure-resistant O157:H7 strains resulting in the viability loss of 4.3-4.6 logs and the synergistic effect increased with increase in treatment time (p high pressure treatment. The synergy between high pressure processing and Lb. casei OSY-LB6A CE against pressure-resistant E. coli O157 strains suggests the feasibility of using this combination to minimize the risk of transmission of E. coli O157 by food.

    This work addresses the inactivation achieved with Escherichia coli O157:H7 and Listeria monocytogenes EGD-e by combined processes of high hydrostatic pressure (HHP) and essential oils (EOs) or their chemical constituents (CCs). HHP treatments (175-400 MPa for 20 min) were combined with 200 μL/L of each EO (Citrus sinensis L., Citrus lemon L., Citrus reticulata L., Thymus algeriensis L., Eucalyptus globulus L., Rosmarinus officinalis L., Mentha pulegium L., Juniperus phoenicea L., and Cyperus longus L.) or each CC ((+)-limonene, α-pinene, β-pinene, p-cymene, thymol, carvacrol, borneol, linalool, terpinen-4-ol, 1,8-cineole, α-terpinyl acetate, camphor, and (+)-pulegone) in buffer of pH 4.0 or 7.0. The tested combinations achieved different degrees of inactivation, the most effective being (+)-limonene, carvacrol, C. reticulata L. EO, T. algeriensis L. EO and C. sinensis L. EO which were capable of inactivating about 4-5 log(10) cycles of the initial cell populations in combination with HHP, and therefore showed outstanding synergistic effects. (+)-Limonene was also capable of inactivating 5 log(10) cycles of the initial E. coli O157:H7 population in combination with HHP (300 MPa for 20 min) in orange and apple juices, and a direct relationship was established between the inactivation degree caused by the combined process with (+)-limonene and the occurrence of sublethal injury after the HHP treatment. This work shows the potential of EOs and CCs in the inactivation of foodborne pathogens in combined treatments with HHP, and proposes their possible use in liquid food such as fruit juices.

    Significant attempts are being made to generate multifunctional, hybrid or peptide combinations as novel therapeutic strategies for type 2 diabetes, however this presents key challenges including design and pharmaceutical development. In this study, we evaluated metabolic properties of oral nutritional supplement epigallocatechin gallate (EGCG) in combination with GLP-1 agonist exendin-4 in a mouse model of dietary-induced diabetes and obesity. EGCG, exendin-4 or combination of both were administered twice-daily over 28 days to high fat (HF) mice on background of low-dose streptozotocin. Energy intake, body weight, fat mass, glucose tolerance, insulin sensitivity, lipid profile, biochemical and hormone markers, and islet histology were examined. All treatment groups exhibited significantly reduced body weight, fat mass, circulating glucose and insulin concentrations, and HbA1c levels which were independent of changes in energy intake. Similarly, there was marked improvement in glycaemic control, glucose-stimulated insulin release, insulin sensitivity, total cholesterol and triglycerides, with most prominent effects observed following combination therapy. Circulating corticosterone concentrations and 11beta-hydroxysteroid dehydrogenase type1 (11β-HSD1) staining (in pancreas) were beneficially decreased without changes in circulating interleukin 6 (IL-6), alanine transaminase (ALT) and glutathione reductase. Combination therapy resulted in increased islet area and number, beta cell area, and pancreatic insulin content. Generally, metabolic effects were much more pronounced in mice which received combination therapy. EGCG alone and particularly in combination with exendin-4 exerts positive metabolic properties in HF mice. EGCG may be useful dietary adjunct alongside GLP-1 mimetics in treatment of diabetes and related disorders. Copyright © 2017 Elsevier B.V. All rights reserved.

  14. Improvement of the wear behaviour of highly-loaded components and tools by multi-combined surface treatment

    Full Text Available This paper introduces a novel multi-combined surface treatment consisting of the individual treatments of plasma nitriding (PN, physical vapour deposition (PVD and electron beam hardening (EBH. Using graded surface layers produced by such a combined surface treatment, it is possible to withstand the complex load conditions incurred by components and tools. It is shown, that the treatment sequences PN+EBH+PVD and EBH+PN+PVD are suitable for improving material properties. These multi-combined surface treatments lead to a significant improvement in load-supporting capacity. Critical load values of cohesive failure measured by scratch tests are tripled when compared to the individual treatment of PVD, and increased by at least 20% in comparison to the duplex treatments of EBH+PVD or PN+PVD. The metallurgical compatibility of the single treatments is essential for the success of combined treatments. Material-specific limitations are defined, which exclude failure due to crack initiation, the occurrence of retained austenite, and tempering effects. Based on the model wear-test assembly block-on-cylinder, it was proved, that the specific wear rate of multi-combined treated specimens is reduced about 20-50% while wear of counterpart components is decreased as well. The triplex surface heat treatment introduced opens up new prospects for highly-loaded components and tools.

    A recent study suggested that college students who combined alcohol and energy drinks were more likely than students who consumed only alcohol to drive when their blood alcohol concentration (BAC) was higher than the .08% limit and to choose to drive despite knowing they had too much alcohol to drive safely. This study sought to replicate those findings with a larger sample while also exploring additional variables related to impaired driving. College students (N = 549) completed an anonymous online survey to assess differences in drinking and driving-related behaviors between alcohol-only users (n = 281) and combined alcohol-energy drink users (n = 268). Combined users were more likely than alcohol-only users to choose to (a) drive when they perceived they were over the .08% BAC limit (35.0% vs. 18.1%, p drinks consumed, number of days drinking, number of days drunk, number of heavy episodic drinking episodes, greatest number of drinks on one occasion, and average hours of consumption. Combined use of alcohol and energy drinks may place drinkers at greater risk when compared with those who consume only alcohol. College students in this sample who combined alcohol and energy drinks were more likely to participate in high-risk driving behaviors than those who consumed only alcohol.

    High pressure structural stability studies were carried out on YGa{sub 2} (AlB{sub 2} type structure at NTP, space group P6/mmm) up to a pressure of ~35 GPa using both laboratory based rotating anode and synchrotron X-ray sources. An isostructural transition with reduced c/a ratio, was observed at ~6 GPa and above ~17.5 GPa, the compound transformed to orthorhombic structure. Bulk modulus B{sub 0} for the parent and high pressure phases were estimated using Birch–Murnaghan and modified Birch–Murnaghan equation of state. Electronic structure calculations based on projector augmented wave method confirms the experimentally observed two high pressure structural transitions. The calculations also reveal that the ‘Ga’ networks remains as two dimensional in the high pressure isostructural phase, whereas the orthorhombic phase involves three dimensional networks of ‘Ga’ atoms interconnected by strong covalent bonds. - Graphical abstract: High pressure X-ray diffraction patterns of YGa{sub 2} up to ~35 GPa shows an isostructural phase transition at ~5 GPa and transition to an orthorhombic structure ~14 GPa. - Highlights: • High pressure structural stability studies were carried out on YGa{sub 2} up to 35 GPa. • An isostructural transition with reduced c/a ratio was observed above 6 GPa. • Above 17.5 GPa, the compound transformed to orthorhombic structure. • PAW based electronic structure calculations have been carried out. • Calculations confirm the experimentally observed structural transitions.

    Full Text Available BACKGROUND: Therapeutic high-frequency ultrasound, microcurrent, and a combination of the two have been used as potential interventions in the soft tissue healing process, but little is known about their effect on the immune system. OBJECTIVE: To evaluate the effects of therapeutic high frequency ultrasound, microcurrent, and the combined therapy of the two on the size of the wound area, peritoneal macrophage function, CD4+ and CD8+, T lymphocyte populations, and plasma concentration of interleukins (ILs. METHOD: Sixty-five Wistar rats were randomized into five groups, as follows: uninjured control (C, group 1, lesion and no treatment (L, group 2, lesion treated with ultrasound (LU, group 3, lesion treated with microcurrent (LM, group 4, and lesion treated with combined therapy (LUM, group 5. For groups 3, 4 and 5, treatment was initiated 24 hours after surgery under anesthesia and each group was allocated into three different subgroups (n=5 to allow for the use of the different therapy resources at on days 3, 7 and 14 Photoplanimetry was performed daily. After euthanasia, blood was collected for immune analysis. RESULTS: Ultrasound increased the phagocytic capacity and the production of nitric oxide by macrophages and induced the reduction of CD4+ cells, the CD4+/CD8+ ratio, and the plasma concentration of IL-1β. Microcurrent and combined therapy decreased the production of superoxide anion, nitric oxide, CD4+-positive cells, the CD4+/CD8+ ratio, and IL-1β concentration. CONCLUSIONS: Therapeutic high-frequency ultrasound, microcurrent, and combined therapy changed the activity of the innate and adaptive immune system during healing process but did not accelerate the closure of the wound.

    This paper presents a novel balun for a millimeter-wave power amplifier (PA) design to achieve high-power density in a 65-nm low-power (LP) CMOS process. By using a concentric winding technique, the proposed parallel combining balun with compact size accomplishes power combining and unbalance-balance conversion concurrently. For calculating its power combination efficiency in the condition of various amplitude and phase wave components, a method basing on S-parameters is derived. Based on the proposed parallel combining balun, a fabricated 60-GHz industrial, scientific, and medical (ISM) band PA with single-ended I/O achieves an 18.9-dB gain and an 8.8-dBm output power at 1-dB compression and 14.3-dBm saturated output power ( P sat) at 62 GHz. This PA occupying only a 0.10-mm2 core area has demonstrated a high-power density of 269.15 mW/mm2 in 65 nm LP CMOS.

    This study investigates the source properties of the 2007 ? 8.0 Pisco, Peru, 2007 ? 8.4 and 7.9 Mentawai Islands, Indonesia, 2009 ? 8.1 Samoa Islands and 2010 ? 8.8 Maule, Chile, earthquakes using a backprojection technique that utilizes data from multiple seismic arrays. Combining seismic arrays increases azimuth and distance coverage and improves lateral resolution. The four subduction interface events show rupture propagation towards the bottom of the seismogenic zone. In addition, all of the earthquakes show evidence of multiple rupture segments with varying rupture speeds and directions. Relating these segments to the specific features of the subduction zones (e.g. interseismic coupling) suggests that asperity sizes may be controlled by subtle features of the subducted slab.

    A new figuring station was designed and installed at the ESRF beamline BM05. It allows the figuring of mirrors within an iterative process combining the advantage of online metrology with dry etching. The complete process takes place under a vacuum environment to minimize surface contamination while non-contact surfacing tools open up the possibility of performing at-wavelength metrology and eliminating placement errors. The aim is to produce mirrors whose slopes do not deviate from the stigmatic profile by more than 0.1 µrad rms while keeping surface roughness in the acceptable limit of 0.1-0.2 nm rms. The desired elliptical mirror surface shape can be achieved in a few iterations in about a one day time span. This paper describes some of the important aspects of the process regarding both the online metrology and the etching process.

    A small scale cook-off experiment has been designed to provide a violence metric for both booster and IHE materials, singly and in combination. The experiment has a simple, axisymmetric geometry provided by a 10 mm internal diameter cylindrical steel confinement up to 80 mm in length. Heating is applied from one end of the sample length creating pseudo 1-D heating profile and a thermal gradient across the sample(s). At the opposite end of the confinement to the heating block, a machined groove provides a point of rupture that generates a cylindrical fragment. The displacement of the external face of the fragment is detected by Heterodyne Velocimetry. Proof of concept experiments are reported focusing on HMX and TATB formulations, and are described in relation to confinement, ullage and heating profile. The development of a violence metric, based upon fragment velocity records is discussed.

    The urban non-point pollution has become main pollution resource of urban water bodies of Shanghai. Character of combined sewer overflow from watershed SA in Shanghai was studied, and the correlation of influence factors to the EMCs of overflows was discussed. It is found that the EMCs of COD, BOD, SS, NH3-N, TN, TP are 614 mg/L, 208.5 mg/L, 684 mg/L, 17.6 mg/L, 29.8 mg/L, 3.0 mg/L respectively, and the values obtained herein are much higher than the documented data from other countries. From the probability plot of the EMCs, it is found that the BOD has the best fitness for lognormal distribution; and correlation between the EMCs of COD, SS and the ratio of antecedent dry weather time to rain duration is quite good.

    Arterial stiffness is associated with the pathogenesis of cerebral microbleeds (CMBs). The ankle-brachial index (ABI) is used to predict arterial stiffness. We hypothesized that the increase in ABI with age occurs as a result of increasing arterial stiffness and wave reflection, and is thus associated with target organ damage. The aim of this study was to investigate the relationship between ABI, brachial-ankle pulse wave velocity (baPWV), and CMBs. We recruited 990 cardiovascular disease-free and stroke-free participants [median age 53 (24-86) years, 531 were woman] who underwent brain MRI, ABI, and baPWV at a health checkup. The prevalence of CMBs was 4%. Both ABI (1.14 vs. 1.10) and baPWV (17.29 vs. 14.68 m/s) were higher in participants with CMBs than those without. Cutoff values of ABI and baPWV for the presence of CMBs were 1.12 and 16.07 m/s, respectively. Multivariate logistic regression analysis showed that ABI at least 1.12 [odds ratio (OR) 2.57, 95% confidence interval (CI) 1.30-5.37, P CMBs. Moreover, the combination of ABI at least 1.12 and baPWV at least 16.07 m/s was strongly associated with CMBs (OR 5.26, 95% CI 1.93-16.92, P CMBs in a screened Japanese cohort, suggesting a novel use for ABI as a predictor for target organ damage.

  6. Combined Saliency with Multi-Convolutional Neural Network for High Resolution Remote Sensing Scene Classification

    2016-09-01

    Full Text Available The scene information existing in high resolution remote sensing images is important for image interpretation and understanding of the real world. Traditional scene classification methods often use middle and low-level artificial features, but high resolution images have rich information and complex scene configuration, which need high-level feature to express. A joint saliency and multi-convolutional neural network method is proposed in this paper. Firstly, we obtain meaningful patches that include dominant image information by saliency sampling. Secondly, these patches will be set as a sample input to the convolutional neural network for training, obtain feature expression on different levels. Finally, we embed the multi-layer features into the support vector machine (SVM for image classification. Experiments using two high resolution image scene data show that saliency sampling can effectively get the main target, weaken the impact of other unrelated targets, and reduce data redundancy; convolutional neural network can automatically learn the high-level feature, compared to existing methods, the proposed method can effectively improve the classification accuracy.

    In this paper, we developed a novel approach for interfacing a microfluidic two-dimensional droplet array to a high-speed capillary electrophoresis (HSCE) system. Picoliter-scale sample injection (ca. 200 pL) from a nanoliter-scale droplet array covered by nonvolatile oil was automatically achieved using the spontaneous injection mode, without the interference from the cover oil and the need of special droplet extraction interface as in previously reported systems. The system was applied in consecutive separations of 25 different samples of amino acids with a whole separation time less than 15 min, as well as on-line monitoring of in-droplet derivatizing reaction of amino acids by fluorescein isothiocyanate (FITC) over 3 hours. High separation speed (up to 100 samples per hour) and high separation efficiency (up to 9.22 × 105 N/m) were achieved.

    Jojoba (Simmondsia chinensis [Link] Schneider) is an important crop in desert climates. A relatively high frequency of periods of chilling and high photon flux density (PFD) in this environment makes photoinhibition likely, resulting in a reduction of assimilation capacity in overwintering leaves. This could explain the low net photosynthesis found in shoots from the field (4-6 micromoles per square meter per second) when compared to greenhouse grown plants (12-15 micromoles per square meter per second). The responses of photosynthesis and stomatal conductance to changes in absorbed PFD and in substomatal partial pressure of CO(2) were measured on jojoba leaves recovering from chilling temperature (4 degrees C) in high or low PFD. No measurable gas exchange was found immediately after chilling in either high or low PFD. For leaves chilled in low PFD, the original quantum yield was restored after 24 hours. The time course of recovery from chilling in high PFD was much longer. Quantum yield recovered to 60% of its original value in 72 hours but failed to recover fully after 1 week. Measurements of PSII chlorophyll fluorescence at 77 K showed that the reduced quantum yield was caused by photoinhibition. The ratio of variable to maximal fluorescence fell from a control level of 0.82 to 0.41 after the photoinhibitory treatment and recovery was slow. We also found a large increase in net assimilation rate and little closure of stomata as CO(2) was increased from ambient partial pressure of 35 to 85 pascals. For plants grown in full light, the increase in net assimilation rate was 100%. The photosynthetic response at high CO(2) concentration may constitute an ecological advantage of jojoba as a crop in the future.

    This report summarizes the work performed between January 2005 and December 2007, under DOE research contract DE-FC26-04NT15507. The project is was performed by the Center for Petroleum and Geosystems Engineering of The University of Texas at Austin and Lawrence Berkeley National Laboratory under the auspices of the National Energy Technology Office (NETL) and the Strategic Center for Natural Gas and Oil (SCNGO). During the three-year project, we developed new methods to combine borehole sonic and electromagnetic (EM) measurements for the improved assessment of elastic and petrophysical properties of rock formations penetrated by a well. Sonic measurements consisted of full waveform acoustic amplitudes acquired with monopole and dipole sources, whereas EM measurements consisted of frequency-domain voltages acquired with multi-coil induction systems. The combination of sonic and EM measurements permitted the joint estimation of elastic and petrophysical properties in the presence of mud-filtrate invasion. It was conclusively shown that the combined interpretation of sonic and EM measurements reduced non-uniqueness in the estimation of elastic and petrophysical properties and improved the spatial resolution of the estimations compared to estimations yielded separately from the two types of measurements. Moreover, this approach enabled the assessment of dynamic petrophysical properties such as permeability, as it incorporated the physics of mud-filtrate invasion in the interpretation of the measurements. The first part of the project considered the development of fast and reliable numerical algorithms to simulate borehole sonic waveforms in 2D, 3D, and radial 1D media. Such algorithms were subsequently used in the quantitative estimation of elastic properties jointly from borehole sonic and EM measurements. In the second part of the project we developed a new algorithm to estimate water saturation, porosity, and dry-rock elastic moduli jointly from borehole sonic and

    Twenty-four high-risk Ewing's sarcoma patients were treated on an intensive combined modality protocol including low-dose fractionated total body irradiaiton (TBI) and autologous bone marrow infusion (ABMI). Twenty patients (83%) achieved a complete clinical response to the primary and/or metastatic sites following induction therapy. The median disease-free interval was 18 months, and nine patients remain disease-free with a follow-up of 22 to 72 months. Local failure as a manifestation of initial relapse occurred in only three patients (15%), each having synchronous distant failure. Eight patients failed initially with only distant metastases, usually within 1-2 years following a complete clinical response. Two patterns of granulocyte recovery following consolidative therapy (including TBI and ABMI) were recognized. The time to platelet recovery was different for the groups with early and late granulocyte recovery. Patients with late recovery did not tolerate maintenance chemotherapy. However, there was no difference in disease-free and overall survival, when comparing the groups with early and late granulocyte recovery. It is concluded that these high-risk Ewing's sarcoma patients remain a poor-prognosis group in spite of intensive combined modality therapy including low-dose TBI. The control of microscopic systemic disease remains the major challenge to improving the cure rate. A new combined modality protocol with high-dose 'therapeutic' TBI (800 rad/2 fractions) is being used and the protocol design is outlined.

    To investigate whether high-intensity focused ultrasound (HIFU) combined with microbubbles enhances the therapeutic effects of chemotherapy. A pancreatic cancer xenograft model was established using BALB/c nude mice and luciferase-expressing human pancreatic cancer cells. Mice were randomly assigned to five groups according to treatment: control (n = 10), gemcitabine alone (GEM; n = 12), HIFU with microbubbles (HIFU + MB, n = 11), combined HIFU and gemcitabine (HIGEM; n = 12), and HIGEM + MB (n = 13). After three weekly treatments, apoptosis rates were evaluated using the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay in two mice per group. Tumor volume and bioluminescence were monitored using high-resolution 3D ultrasound imaging and in vivo bioluminescence imaging for eight weeks in the remaining mice. The HIGEM + MB group showed significantly higher apoptosis rates than the other groups (p < 0.05) and exhibited the slowest tumor growth. From week 5, the tumor-volume-ratio relative to the baseline tumor volume was significantly lower in the HIGEM + MB group than in the control, GEM, and HIFU + MB groups (p < 0.05). Despite visible distinction, the HIGEM and HIGEM + MB groups showed no significant differences. High-intensity focused ultrasound combined with microbubbles enhances the therapeutic effects of gemcitabine chemotherapy in a pancreatic cancer xenograft model.

    Aim: To evaluate the diagnostic performance of the combined use of elstosonography (USE) scoring and high-resolution ultrasonography (HRUS) for the differentiation of benign and malignant thyroid nodule. Patients and methods: Forty-seven consecutive patients with 66 thyroid nodules were enrolled in the present study. Thyroid surgery had been already planned for all the patients. All of them were submitted to high-resolution ultrasonography and elastography scoring at the same sitting. The latter was determined with 5-point scoring method. The examination results were compared against pathological findings as the gold standard of reference. Results: The sensitivity, specificity, accuracy, positive predictive, and negative predictive values of HRUS in the differential diagnosis of thyroid nodules were 92.0%, 72.9%, 60.1%, 95.0%, and 63.1%, respectively, while that of ultrasound elastography scoring were 75.4%, 85.5%, 86.7%, 71.4%, and 90.5%, respectively. Combined use of both US techniques resulted in a higher diagnostic performance as it showed 95.4%, 94.8%, 95.2%, 82.3% and 98.8% sensitivity, specificity, accuracy, positive predictive, and negative predictive values, respectively. Conclusions: The use of combined USE and HRS for the differentiation of benign and malignant thyroid nodules resulted in a high diagnostic performance and a significant statistical difference as compared to HRUS or USE alone (P = 0.003)

    To assess the association between high body mass index (BMI) and treatment response in recent-onset rheumatoid arthritis. In the Behandelstrategieën voor Reumatoide Artritis (Treatment Strategies for Rheumatoid Arthritis) study, 508 patients were randomized to initial monotherapy or combination therapy with prednisone or infliximab (IFX). The response to Disease Activity Score (DAS) ≤2.4-steered treatment (first dose and after 1 year) was compared between patients with a BMI <25 kg/m(2) and ≥25 kg/m(2) , using relative risk (RR) regression analyses. DAS, components of DAS, and functional ability during the first year were compared using linear mixed models. High BMI was independently associated with failure to achieve a DAS ≤2.4 on initial therapy (RR 1.20 [95% confidence interval (95% CI) 1.05, 1.37]). The effect for combination therapy with prednisone was RR 1.55 (95% CI 1.06, 2.28) and for combination therapy with IFX 1.42 (95% CI 0.98, 2.06). The RRs for failure after 1 year were 1.46 (95% CI 0.75, 2.83) and 2.20 (95% CI 0.99, 4.92), respectively. High BMI was also associated with failure on delayed combination therapy with IFX, after adjustment for selection bias related to previous failure on disease-modifying antirheumatic drugs. No significant association was observed in the initial monotherapy groups. In the first year, patients with a high BMI had higher DAS and worse functional ability, with more tender joints and a higher visual analog scale global health, but not more swollen joints and similar systemic inflammation. High BMI was independently associated with failure to achieve low DAS on initial combination therapy with prednisone and on initial and delayed treatment with IFX. Patients with a high BMI experienced more pain, but not more swelling or systemic inflammation. Copyright © 2013 by the American College of Rheumatology.

    The objective of this study is to investigate if quantitative imaging features derived from combined (18)F-Fluciclovine Positron Emission Tomograpy (PET) / multiparametric Magnetic Resonance Imaging (MRI) show potential for detection and characterization of primary prostate cancer. Methods: Twenty-eight (28) patients diagnosed with high-risk prostate cancer underwent simultaneous (18)F-Fluciclovine PET/MRI before radical prostatectomy. Volumes-of-interest (VOIs) of prostate tumors, benign prostatic hyperplasia (BPH) nodules, prostatitis, and healthy tissue were delineated on T2-weighted images using histology as a reference. Tumor VOIs were marked as high-grade (≥ Gleason Grade group 3) or not. MRI and PET features were extracted on the voxel and VOI-level. Partial least-squared discriminant analysis (PLS-DA) with double leave-one-patient-out cross validation was performed to classify tumor from benign tissue (BPH, prostatitis, healthy tissue) and high-grade tumor from other tissue (low-grade tumor, benign tissue). The performances of PET, MRI, and combined PET/MRI features were compared using the area under the receiver operating characteristic curve (AUC). Results: Voxel and VOI features were extracted from 40 tumor (26 high-grade), 36 BPH, 6 prostatitis, and 37 healthy tissue VOIs. PET/MRI performed better than MRI and PET for classification of tumor vs benign tissue (voxel: AUC 87%, 81%, and 83%; VOI: AUC 96%, 93%, and 93%, respectively) and high-grade tumor vs other tissue (voxel: AUC 85%, 79%, and 81%; VOI: AUC 93%, 93%, and 91%, respectively). T2-weighted MRI, diffusion-weighted MRI and PET features were most important for classification. Conclusion: Combined (18)F-Fluciclovine PET/multiparametric MRI shows potential for improving detection and characterization of high-risk prostate cancer, in comparison to MRI and PET alone.
