    Full Text Available Research on person categorization suggests that people automatically and inflexibly categorize others according to group memberships, such as race. Consistent with this view, research using electroencephalography (EEG has found that White participants tend to show an early difference in processing Black versus White faces. Yet, new research has shown that these ostensibly automatic biases may not be as inevitable as once thought and that motivational influences may be able to eliminate these biases. It is unclear, however, whether motivational influences shape the initial biases or whether these biases can only be modulated by later, controlled processes. Using EEG to examine the time course of biased processing, we manipulated approach and avoidance motivational states by having participants pull or push a joystick, respectively, while viewing White or Black faces. Consistent with previous work on own-race bias, we observed a greater P100 response to White than Black faces; however, this racial bias was attenuated in the approach condition. These data suggest that rapid social perception may be flexible and can be modulated by motivational states.

    Compared to approach motivation, avoidance motivation evokes vigilance, attention to detail, systematic information processing, and the recruitment of cognitive resources. From a conservation of energy perspective it follows that people would be reluctant to engage in the kind of effortful cognitive

    The present study investigated the effects of approach versus avoidance motivation on declarative learning. Human participants navigated a virtual reality version of the Morris water task, a classic spatial memory paradigm, adapted to permit the experimental manipulation of motivation during learning. During this task, participants were instructed to navigate to correct platforms while avoiding incorrect platforms. To manipulate motivational states participants were either rewarded for naviga...

    Consumption of a sweet solution (the CS) and ultrasonic vocalizations (USVs) emitted by rats were recorded in a conditioned taste avoidance paradigm. The rats' affective states were inferred from a ratio of high to low-frequency ultrasonic calls, which have been associated with positive and negative affect, respectively. The interacting effects of deprivation state and lesions of the basolateral amygdala (BLA) on CS consumption and affective state were examined. Rats were trained during the light phase while either 23 h or 3h water deprived by exposing them to the CS and then injecting them with LiCl or saline. They were tested by re-exposing them to the CS while either 23 or 3h deprived. Sham-lesioned rats that received LiCl injections consumed significantly less of the CS and evidenced relatively negative affect (inferred from the USV ratio) compared to control rats that received saline injections, regardless of the deprivation state in which they were trained or tested. Rats with BLA lesions trained while 23 h deprived failed to exhibit either reduced consumption or negative affect, regardless of whether they were tested while deprived for 23 or 3h. Identical lesions had no effect on reduced consumption or on negative affect in rats trained while 3h deprived, regardless of whether they were tested while deprived for 3 or 23 h. The findings suggest that both reduced consumption and negative affect are the results of different learning processes in deprived (23 h) and nearly satiated (3h, during the light phase) rats. The amygdala-dependent negative affective shift observed in deprived rats may be due to an aversive Pavlovian conditioned response that acts to suppress drinking. The amygdala-independent negative affective response and reduced consumption in nearly satiated rats could be due to a form of latent learning of a stimulus-outcome association. PMID:20888864

  5. Effects of optimism on creativity under approach and avoidance motivation

    OpenAIRE

    Icekson, Tamar; Roskes, Marieke; Moran, Simone

    2014-01-01

    Focusing on avoiding failure or negative outcomes (avoidance motivation) can undermine creativity, due to cognitive (e.g., threat appraisals), affective (e.g., anxiety), and volitional processes (e.g., low intrinsic motivation). This can be problematic for people who are avoidance motivated by nature and in situations in which threats or potential losses are salient. Here, we review the relation between avoidance motivation and creativity, and the processes underlying this relation. We highli...

  6. The mnemonic mover: nostalgia regulates avoidance and approach motivation

    2014-01-01

    In light of its role in maintaining psychological equanimity, we proposed that nostalgia—a self-relevant, social, and predominantly positive emotion—regulates avoidance and approach motivation. We advanced a model in which (a) avoidance motivation triggers nostalgia and (b) nostalgia, in turn, increases approach motivation. As a result, nostalgia counteracts the negative impact of avoidance motivation on approach motivation. Five methodologically diverse studies supported this regulatory mode...

    Approach motivation leads to greater left hemisphere activation, whereas an avoidant motivational state activates the right hemisphere. Recent research, which served as the basis for the current experiment, suggests line bisection provides a simple measure of approach/avoidance lateralisation. Findings from Experiment 1 indicated that the landmark task was sensitive enough to identify lateral asymmetries evoked by happy and angry faces; however, follow-up experiments failed to replicate this finding. When task instructions were slightly modified or when a mixed design was used, motivation did not influence landmark task performance. The use of images in lieu of faces also failed to produce a significant effect. Importantly, a straight replication of Experiment 1 produced a null result. Line bisection does not appear to be a suitable measure of lateralised approach/avoidance biases, possibly due to the high individual variability inherent in visuospatial biases. Implications for null hypothesis significance testing are also discussed. PMID:26211805

    2012-08-01

    Compared with approach motivation, avoidance motivation has often been related to reduced creativity because it evokes a relatively inflexible processing style. This finding seems inconsistent with the dual pathway to creativity model, which poses that both flexible and persistent processing styles can result in creative output. Reconciling these inconsistencies, the authors hypothesized that avoidance-motivated individuals are not unable to be creative, but they have to compensate for their inflexible processing style by effortful and controlled processing. Results of 5 experiments revealed that when individuals are avoidance motivated, they can be as creative as when they are approach motivated, but only when creativity is functional for goal achievement, motivating them to exert the extra effort (Experiments 1-4). The authors found that approach motivation was associated with cognitive flexibility and avoidance motivation with cognitive persistence (Experiment 1), that creative tasks are perceived to be more difficult by avoidance- than by approach-motivated individuals, and that avoidance-motivated individuals felt more depleted after creative performance (Experiment 2a, 2b, and 3). Finally, creative performance of avoidance-motivated individuals suffered more from a load on working memory (Study 4). The present results suggest that for people focusing on avoiding negative outcomes, creative performance is difficult and depleting, and they only pay these high cognitive costs when creativity helps achieving their goals.

    Neurobiological theories predict decreased approach motivation and increased avoidance motivation in depression, but the results of previous studies have been equivocal. This study addressed a key limitation of previous research by assessing participants' underlying motivation for adopting their goals. Depressed (N=26) and non-depressed (N=33) participants listed approach and avoidance goals and wrote down their underlying reasons for adopting those goals. The groups did not differ on either the number of goals or underlying reasons but when underlying reasons were coded for approach or avoidance motivation depressed participants, compared to controls, showed less approach motivation and more avoidance motivation in relation to their approach goals. There were no effects related to avoidance goals. The results suggest that while the goals of depressed persons appear to be similar to those who are not depressed there are important differences at the level of underlying motivation. PMID:23627339

    Full Text Available The Motive to Achieve Success (MAS and the Motive to Avoid Failure (MAF are the most widely measured factors of achievement motivation. The relationships between MAS and MAF are controversial. To test the validity of these relations, we compared three models with different relationships between MAS and MAF by confirmatory factor analyses. Items from the achievement motivation subscale of the personality research form (Jackson, 1999 and from the motive to avoid failure scale (Hagtvet & Benson, 1997 were administrated to a large sample ('N' = 1179. The model in which MAS and MAF were separable and weakly correlated factors showed better results than independent and unitary models. Implications for the selection of participants were also discussed.

  14. Measuring motivation in schizophrenia: is a general state of motivation necessary for task-specific motivation?

    2014-03-01

    Despite the important role of motivation in rehabilitation and functional outcomes in schizophrenia, to date, there has been little emphasis on how motivation is assessed. This is important, since different measures may tap potentially discrete motivational constructs, which in turn may have very different associations to important outcomes. In the current study, we used baseline data from 71 schizophrenia spectrum outpatients enrolled in a rehabilitation program to examine the relationship between task-specific motivation, as measured by the Intrinsic Motivation Inventory (IMI), and a more general state of volition/initiation, as measured by the three item Quality of Life (QLS) motivation index. We also examined the relationship of these motivation measures to demographic, clinical and functional variables relevant to rehabilitation outcomes. The two motivation measures were not correlated, and participants with low general state motivation exhibited a full range of task-specific motivation. Only the QLS motivation index correlated with variables relevant to rehabilitation outcomes. The lack of associations between QLS motivation index and IMI subscales suggests that constructs tapped by these measures may be divergent in schizophrenia, and specifically that task-specific intrinsic motivation is not contingent on a general state of motivation. That is, even in individuals with a general low motivational state (i.e. amotivation), interventions aimed at increasing task-specific motivation may still be effective. Moreover, the pattern of interrelationships between the QLS motivation index and variables relevant to psychosocial rehabilitation supports its use in treatment outcome studies. PMID:24529609

    Whites' nonprejudiced behavior toward racial/ethnic minorities can be attributionally ambiguous for perceivers, who may wonder whether the behavior was motivated by a genuine internal commitment to egalitarianism or was externally motivated by desires to avoid appearing prejudiced to others. This article reports the development of a scale that measures perceptions of Whites' internal and external motives for avoiding prejudice (Perceived Internal Motivation Scale/Perceived External Motivation Scale [PIMS/PEMS]) and tests of its internal, test-retest, discriminant, convergent, and predictive validity among ethnic minority perceivers. Minorities perceived Whites as having internal and external motives for nonprejudiced behavior that were theoretically consistent with but distinct from established measures of minority-group members' concerns in interracial interactions. Tests of the predictive validity of PIMS/PEMS showed that when a White evaluator praised the mediocre essay of a minority target, minorities who were high PEMS and low PIMS were most likely to regard the feedback as inauthentic and derogate the quality of the essay.

    Health messages framed to be congruent with individuals' approach/avoidance motivations have been found to be more effective in promoting health behaviors than health messages incongruent with approach/avoidance motivations. This study examines the processes underlying this congruency effect. Participants (undergraduate students, N = 67) completed a measure of approach/avoidance orientation (the BIS/BAS scales) and read either a gain- or loss-framed message promoting dental flossing. Results demonstrated a congruency effect: Participants who read a congruently framed message had greater flossing efficacy, intended to floss more, and used more dental flosses than did the participants who read an incongruent message. Moreover, intention to perform the behavior predicted the congruency effect and self-efficacy mediated participants' intentions to perform the health behavior. Discussion centers on the role of personality factors and situational factors in models of behavior change. PMID:19079797

    Even when people with schizophrenia describe themselves as generally motivated and eager to engage in activities, they may not actually be motivated in the present moment. In order to better understand the relationship between trait and state motivation, we aimed to assess trait motivation and state intrinsic motivation, and investigate their relations to each other and to criterion-related variables including cognition, negative symptoms, and beliefs about one's own competency-also known as perceived competency (PC). Further, we investigated whether PC mediates the relationships between state intrinsic motivation (IM) and trait motivation dimensions. Forty individuals with schizophrenia or schizoaffective disorders were administered two self-report measures of motivation, the Motivational Trait Questionnaire (Kanfer, R., Ackerman, P., 2000. Individual differences in work motivation: further explorations of a trait framework. Appl. Psychol. 49 (3), 470-482) and the Intrinsic Motivation Inventory for Schizophrenia Research (Choi, J., Medalia, A., 2010. Intrinsic motivation and learning in a schizophrenia spectrum sample. Schizophr. Res. 118, 12-19), as well as measures of PC, cognition and symptoms. The results showed that in people with schizophrenia, trait approach motivation, but not trait avoidance motivation, is positively correlated with state intrinsic motivation and PC. There was evidence that PC partially mediates the relationship between trait approach motivation and state intrinsic motivation to do the task. These results support the role of therapies that directly address self-competency beliefs and set the groundwork for future investigations on the impact of such treatments on motivation.

    Northern European countries lose more than ten percent of their university graduates as a result of emigration. This could undermine welfare states if the high-income earners emigrate to avoid high taxes. Register data shows that those facing a high tax burden are much more likely to emigrate. Yet...... little is known about individual motivations to emigrate. To bridge this gap, we organized the first-ever survey of emigrants from a welfare state. We find that migration decisions are rarely driven by taxes. For men, the main reason to emigrate is own work, for women partner and family....

    Full Text Available Several emotion theorists suggest that valenced stimuli automatically trigger motivational orientations and thereby facilitate corresponding behavior. Positive stimuli were thought to activate approach motivational circuits which in turn primed approach-related behavioral tendencies whereas negative stimuli were supposed to activate avoidance motivational circuits so that avoidance-related behavioral tendencies were primed (motivational orientation account. However, recent research suggests that typically observed affective stimulus–response compatibility phenomena might be entirely explained in terms of theories accounting for mechanisms of general action control instead of assuming motivational orientations to mediate the effects (evaluative coding account. In what follows, we explore to what extent this notion is applicable. We present literature suggesting that evaluative coding mechanisms indeed influence a wide variety of affective stimulus–response compatibility phenomena. However, the evaluative coding account does not seem to be sufficient to explain affective S–R compatibility effects. Instead, several studies provide clear evidence in favor of the motivational orientation account that seems to operate independently of evaluative coding mechanisms. Implications for theoretical developments and future research designs are discussed.

    The motive to achieve success (MAS) and motive to avoid failure (MAF) are two different but classical kinds of achievement motivation. Though many functional magnetic resonance imaging studies have explored functional activation in motivation-related conditions, research has been silent as to the brain structures associated with individual differences in achievement motivation, especially with respect to MAS and MAF. In this study, the voxel-based morphometry method was used to uncover focal differences in brain structures related to MAS and MAF measured by the Mehrabian Achieving Tendency Scale in 353 healthy young Chinese adults. The results showed that the brain structures associated with individual differences in MAS and MAF were distinct. MAS was negatively correlated with regional gray matter volume (rGMV) in the medial prefrontal cortex (mPFC)/orbitofrontal cortex while MAF was negatively correlated with rGMV in the mPFC/subgenual cingulate gyrus. After controlling for mutual influences of MAS and MAF scores, MAS scores were found to be related to rGMV in the mPFC/orbitofrontal cortex and another cluster containing the parahippocampal gyrus and precuneus. These results may predict that compared with MAF, the generation process of MAS may be more complex and rational, thus in the real world, perhaps MAS is more beneficial to personal growth and guaranteeing the quality of task performance.

    Integrating implications from regulatory focus and approach/avoidance motivation theories, we present a framework wherein motivational orientations toward positive (approach motivation orientation) or negative (avoidance motivation orientation) stimuli interact with workplace success to mediate the relation of core self-evaluation (CSE) with job satisfaction. Using data collected from supervisor-subordinate dyads (Sample 1) and time-lagged data (Sample 2), we found that the results from two studies indicated that the interaction of workplace success and avoidance motivation orientation mediated relations of CSE with job satisfaction. Although approach motivation orientation did not interact with workplace success, it did mediate the CSE-job satisfaction relation on its own. Implications for the CSE and approach/avoidance literatures are discussed. PMID:22963514

    Grounded in achievement goal theory and self-determination theory, this cross-sectional study examined the relationship between perceived motivational climate and individuals' motivation as well as the mediation effect of psychobiosocial states as conceptualised within the individual zones of optimal functioning (IZOF) model. Young students (N = 167, age range 14-15 years) taking part in physical education classes completed measures of teacher-initiated motivational climate, task and ego orientation, motivation and psychobiosocial states. Simple and serial mediation analyses indicated that a perceived mastery climate and individuals' task orientation were related to intrinsic motivation and identified regulation through the mediation of pleasant/functional psychobiosocial states. In contrast, a perceived performance climate was related to external regulation and amotivation through the mediation of unpleasant/dysfunctional psychobiosocial states. Regression analysis results also showed that discrete psychobiosocial states accounted for a significant proportion of variance in motivational variables. Taken together, findings highlight the role of psychobiosocial states as mediators of the relationship between motivational climate and an individual's motivation, and suggest that educators should consider a wide range of individual's functional and dysfunctional reactions deriving from their instructional activity.

  8. Truth, Control, and Value Motivations: The ‘What,’ ‘How,’ and ‘Why’ of Approach and Avoidance

    Directory of Open Access Journals (Sweden)

    James F. M. Cornwell

    2014-10-01

    Full Text Available The hedonic principle—the desire to approach pleasure and avoid pain—is frequently presumed to be the fundamental principle upon which motivation is built. In the past few decades, researchers have enriched our understanding of how approaching pleasure and avoiding pain differ from each other. However, more recent empirical and theoretical work delineating the principles of motivation in humans and non-human animals has shown that not only can approach/avoidance motivations themselves be further distinguished into promotion approach/avoidance and prevention approach/avoidance, but that approaching pleasure and avoiding pain requires the functioning of additional distinct motivations—the motivation to establish what is real (truth and the motivation to manage what happens (control. Considering these additional motivations in the context of moral psychology and animal welfare science suggests that these less-examined motives may themselves be fundamental to a comprehensive understanding of motivation, with major implications for the study of the “what,” “how,” and “why” of human and non-human approach and avoidance behavior.

    Full Text Available This chapter investigates the importance of motivation. It examines the importance of the use of the audio-visual-kinaesthetic means of motivation in a young learner context through a theoretical and practical framework. The concept of motivation, its definition and its components as well as the factors that affect it, along with its relation to learning theories concerning how young learners are motivated are examined and analysed. However, young learners’ motivation is positively or negatively influenced by the teaching process- a factor that is directly related to the application and the use of the audio-visual-kinaesthetic means of motivation. Certain questions and issues associated with the use, the necessity, the effectiveness of these means are discussed in conjunction with what happens in the Greek state primary school. A research done in a substantial number of state primary schools enlightens us about teachers’ and students’ response to audio-visual-kinaesthetic means of motivation, the frequency with which they are used and the factors that affect it. All these theoretical and practical issues are presented, justified and evaluated,while specific implications are presented with a view to making teaching and learning interesting and beneficial for both teachers and learners.

    2016-01-01

    This study examined the association between infant facial expressions and parental motivation as well as the interaction between attachment state and expressions. Two-hundred eighteen childless adults (Mage = 19.22, 118 males, 100 females) were recruited. Participants completed the Chinese version of the State Adult Attachment Measure and the E-prime test, which comprised three components (a) liking, the specific hedonic experience in reaction to laughing, neutral, and crying infant faces; (b) representational responding, actively seeking infant faces with specific expressions; and (c) evoked responding, actively retaining images of three different infant facial expressions. While the first component refers to the “liking” of infants, the second and third components entail the “wanting” of an infant. Random intercepts multilevel models with emotion nested within participants revealed a significant interaction between secure attachment state and emotion on both liking and representational response. A hierarchical regression analysis was conducted to examine the unique contributions of secure attachment state. Findings demonstrated that, after controlling for sex, anxious, and avoidant, secure attachment state positively predicted parental motivations (liking and wanting) in the neutral and crying conditions, but not the laughing condition. These findings demonstrate the significant role of secure attachment state in parental motivation, specifically when infants display uncertain and negative emotions. PMID:27582724

  17. Driving Demand for Home Energy Improvements: Motivating residential customers to invest in comprehensive upgrades that eliminate energy waste, avoid high utility bills, and spur the economy

    Energy Technology Data Exchange (ETDEWEB)

    Fuller, Merrian C.

    2010-09-20

    Policy makers and program designers in the U.S. and abroad are deeply concerned with the question of how to scale up energy efficiency to a level that is commensurate both to the scale of the energy and climate challenges we face, and to the potential for energy savings that has been touted for decades. When policy makers ask what energy efficiency can do, the answers usually revolve around the technical and economic potential of energy efficiency - they rarely hone in on the element of energy demand that matters most for changing energy usage in existing homes: the consumer. A growing literature is concerned with the behavioral underpinnings of energy consumption. We examine a narrower, related subject: How can millions of Americans be persuaded to divert valued time and resources into upgrading their homes to eliminate energy waste, avoid high utility bills, and spur the economy? With hundreds of millions of public dollars flowing into incentives, workforce training, and other initiatives to support comprehensive home energy improvements, it makes sense to review the history of these programs and begin gleaning best practices for encouraging comprehensive home energy improvements. Looking across 30 years of energy efficiency programs that targeted the residential market, many of the same issues that confronted past program administrators are relevant today: How do we cost-effectively motivate customers to take action? Who can we partner with to increase program participation? How do we get residential efficiency programs to scale? While there is no proven formula - and only limited success to date with reliably motivating large numbers of Americans to invest in comprehensive home energy improvements, especially if they are being asked to pay for a majority of the improvement costs - there is a rich and varied history of experiences that new programs can draw upon. Our primary audiences are policy makers and program designers - especially those that are relatively

    We hypothesize that, in their annual accounting reports, insurers allocate premiums and losses from multistate policies to reduce total state taxes. To test this prediction, we examine firm-level data, collected from the publicly-available statutory reports used to compute tax bases and filed with each state government. If insurers manage allocations to avoid taxes, we anticipate an inverse relation between the tax rate and the premium-to-loss ratio, which is the industry's standard measure o...

  20. Empathy: a motivated account.

    Science.gov (United States)

    Zaki, Jamil

    2014-11-01

    Empathy features a tension between automaticity and context dependency. On the one hand, people often take on each other's internal states reflexively and outside of awareness. On the other hand, empathy shifts with characteristics of empathizers and situations. These 2 characteristics of empathy can be reconciled by acknowledging the key role of motivation in driving people to avoid or approach engagement with others' emotions. In particular, at least 3 phenomena-suffering, material costs, and interference with competition-motivate people to avoid empathy, and at least 3 phenomena-positive affect, affiliation, and social desirability-motivate them to approach empathy. Would-be empathizers carry out these motives through regulatory strategies including situation selection, attentional modulation, and appraisal, which alter the course of empathic episodes. Interdisciplinary evidence highlights the motivated nature of empathy, and a motivated model holds wide-ranging implications for basic theory, models of psychiatric illness, and intervention efforts to maximize empathy.

    Hamish Gillies

    2010-12-01

    Full Text Available This paper reports on a follow-up study to Gillies (2007, in which a survey was conducted to investigate how tertiary-level Japanese EFL students understand and interpret their use or non-use of their institution’s self-access centre (SAC. The survey data revealed general trends regarding the factors which motivate the students’ use of the SAC as well as reasons why students choose not to use it, while also suggesting four types of students, via cluster analysis. Employing Dornyei’s (2005 L2 Motivational Self System as a theoretical framework, the current paper attempts to probe deeper into the survey data, and specifically tease out the factors influencing the use or non-use of the SAC. It reports on a set of semi-structured interviews with a purposeful sample of nine students from amongst the survey respondents. The interviewees included representatives of each of the four clusters identified in the survey data. The interview transcripts were then subjected to coding and labelling, and key themes in the data emerged: the SAC as an environment; the SAC as a community of selves; the SAC as contrasted with the classroom. Related to these themes, it was found that in the first year of university, identities are forged, distinguishing regular SAC users and rare SAC users. The SAC is an attractive environment for students with strong ideal L2 selves, while being uncomfortable for less confident students. The former type of student is more likely to see the classroom environment as restrictive, while the latter views it as sheltered and supportive. Meanwhile, the level of English proficiency is not in itself predictive of SAC use, but rather the level of L2 motivation, in particular the strength of the learner’s ideal L2 self. The paper discusses these themes and findings, and concludes with implications for the SAC, and suggestions for making the centre accessible and appealing to a wider cross-section of the overall student body.

    Full Text Available The purpose of this study was to analyze motivational profiles based on the self-determination theory (Deci and Ryan, 2000 and how these profiles are related to physical education students' enjoyment, state anxiety, and physical activity. The participants, 429 sixth grade students (girls = 216; boys = 213 completed SMS, Sport Enjoyment Scale, PESAS, and Physical Activity Scale. Cluster analyses identified two motivational profiles: 1 the "High motivation profile", in which the students had high intrinsic and extrinsic motivation, and low levels of amotivation, and 2 the "Low motivation profile", in which the students had low intrinsic and extrinsic motivation, and low levels of amotivation. The students in the first cluster enjoyed physical education more and were physically more active. The results revealed that students may be motivated towards physical education lessons both intrinsically and extrinsically, and still experience enjoyment in physical education.

    Brian P Meier

    Full Text Available BACKGROUND: A basic premise of the recently proffered color-in-context model is that the influence of color on psychological functioning varies as a function of the psychological context in which color is perceived. Some research has examined the appetitive and aversive implications of viewing the color red in romance- and achievement-relevant contexts, respectively, but in all existing empirical work approach and avoidance behavior has been studied in separate tasks and separate experiments. Research is needed to directly test whether red influences the same behavior differently depending entirely on psychological context. METHODOLOGY/PRINCIPAL FINDINGS: The present experiment was designed to put this premise to direct test in romance- and achievement-relevant contexts within the same experimental paradigm involving walking behavior. Our results revealed that exposure to red (but not blue indeed has differential implications for walking behavior as a function of the context in which the color is perceived. Red increased the speed with which participants walked to an ostensible interview about dating (a romance-relevant context, but decreased the speed with which they walked to an ostensible interview about intelligence (an achievement-relevant context. CONCLUSIONS/SIGNIFICANCE: These results are the first direct evidence that the influence of red on psychological functioning in humans varies by psychological context. Our findings contribute to both the literature on color psychology and the broader, emerging literature on the influence of context on basic psychological processes.

  8. Avoidance-related EEG asymmetry predicts circulating interleukin-6.

    Shields, Grant S; Moons, Wesley G

    2016-03-01

    Recent research has linked avoidance-oriented motivational states to elevated pro-inflammatory cytokine levels. According to one of many theories regarding the association between avoidance and cytokine levels, because the evolutionarily basic avoidance system may be activated when an organism is threatened or overwhelmed, an associated inflammatory response may be adaptive for dealing with potential injury in such threatening situations. To examine this hypothesis, we tested whether the neural correlate of avoidance motivation associates with baseline levels of the circulating pro-inflammatory cytokine interleukin-6 (IL-6). Controlling for covariates, greater resting neural activity in the right frontal cortex relative to the left frontal cortex-the neural correlate of avoidance motivation-was associated with baseline IL-6. These results thus support the hypothesis that the avoidance motivational system may be closely linked to systemic inflammatory activity. PMID:26461246

    Full Text Available Although many studies within the field of educational psychology have addressed the issue of students’ motivation, not as much attention has been given to teacher motivation. The present study aims at examining the factors that motivate EFL teachers working at Greek State Primary and Secondary schools, highlighting the importance of these factors for the improvement and enhancement of the teaching performance. The results of the study indicated that EFL teachers are quite motivated. Motivating factors are mostly intrinsic in nature, while demotivation rises mainly from extrinsic factors. Among the most powerful motivators were the teachers’ relation with their students and the subject matter itself, while frequent educational reforms and poor remuneration were identified as highly demotivating factors. Given that teachers’ motivation directly influences students’ motivation, highly motivated teachers are crucial for an effective educational system. Consequently, an important part of education policy-making should be the enhancement of teacher motivation as well as the reduction or elimination of any factors that impede teachers’ performance.

The complex of diagnostic methods was used to determine the level of professional-pedagogical motivation, which was directed on outlining motivation components and its development levels determination. The research involved 232 students. It was found that for the 1 st year students the first place was obtained by the professional-cognitive interest, second by achievement motive and third by professional intention. For the 4 th year students, the first place is possessed by professional cognitive interest, then followed by motives referred to professional and then – motives of achievement. The diagnostics have outlined absence of certain professional intentions. Also from first to fourth year of studies the tendency of increasing the amount of students interest of which is not connected either to physical culture, sports nor to pedagogical activity is followed.

    Motivational states are important determinants of behavior. In fruit flies appetitive memory expression is constrained by satiety and promoted by hunger. Here we identify a neural mechanism that integrates the motivational state of hunger and memory. We show that stimulation of neurons that express Neuropeptide F (dNPF), an ortholog of mammalian NPY, mimicks food-deprivation and promotes memory performance in satiated flies. Robust appetitive memory performance requires the dNPF receptor in s...

    This study explores the importance of different motivations to visit three types of recreational settings—farms, private forests, and state or national parks. Data were collected via a mail-back questionnaire administered to a stratified random sample of households in Missouri (USA). Descriptive and inferential statistics reveal both similarities and discontinuities in motivations for visiting farms, private forests, and state or national parks for recreation. Being with family, viewing natural scenery, and enjoying the smells and sounds of nature were all highly important motivations for visiting the three types of settings. However, all 15 motivations examined were perceived to be significantly more important for visits to state or national parks than to farms or private forests. Findings suggest that individuals are more strongly motivated to recreate at state and national parks relative to farmlands or forests. Post hoc paired t tests comparing motivations between both agricultural settings (farms and private forests) revealed significant differences in eight different recreational motivations. Individuals tended to place more importance on the ability to use equipment and test their skills when considering recreating on private forests. Conversely, social motivations (e.g., doing something with the family) were more important when individuals were considering recreating on farmland. Collectively, the findings suggest individuals expect distinctly different outcomes from their visits to farmlands, private forests, or state or national parks. Consequently, all three types of recreational settings have competitive advantages that their managers could capitalize on when making decisions about how to attract new visitors or produce the most desirable experiences for current recreationists.

    Directory of Open Access Journals (Sweden)

    Eddie Harmon-Jones

    2012-09-01

    Full Text Available We review a program of research that has suggested that affective states high in motivationally intensity (e.g., enthusiasm, disgust narrow cognitive scope, whereas affective states low in motivationally intensity (e.g., joy, sadness broaden cognitive scope. Further supporting this interpretation, indices of brain activations, derived from human electroencephalography, suggest that the motivational intensity of the affective state predicts the narrowing of cognitive scope. Finally, research suggests that the relationship between emotive intensity and cognitive scope is bi-directional, such that manipulated changes in cognitive scope influence early brain activations associated with emotive intensity. In the end, the review highlights how emotion can impair and improve certain cognitive processes.

  19. Dorsal raphe nucleus and harm avoidance: A resting-state investigation.

    Science.gov (United States)

    Meylakh, N; Henderson, L A

    2016-06-01

    The temperament dimension of harm avoidance defines an individual's biological tendency to exhibit altering levels of anxious, inhibiting, and cautious behavior. High harm avoidance and anxiety are highly comorbid, likely due to activity in similar neural circuitries involving the dorsal raphe nucleus. Despite the many investigations that have explored personality factors and brain function, none have determined the influence of ongoing activity within dorsal raphe networks on harm avoidance. The aim of this study was to explore such a relationship. In 62 healthy subjects, a series of 180 functional magnetic resonance images covering the entire brain were collected, and each subject completed the 240-item TCI-R questionnaire. Independent component analyses were performed to define the dorsal raphe network and then to determine the regions significantly correlated with harm avoidance. The independent component analyses revealed three signal intensity fluctuation maps encompassing the dorsal raphe nucleus, showing interactions with regions of the amygdala, hippocampus, nucleus accumbens, and prefrontal, insular, and cingulate cortices. Within these systems, the resting signal intensity was significantly coupled to harm avoidance in the bilateral basal amygdala, bilateral ventral hippocampus, bilateral insula, bilateral nucleus accumbens, and medial prefrontal cortex. Note that we could not measure serotonergic output, but instead measured signal changes in the dorsal raphe that likely reflect synaptic activity. These data provide evidence that at rest, signal intensity fluctuations within the dorsal raphe networks are related to harm avoidance. Given the strong relationship between harm avoidance and anxiety-like behaviors, it is possible that ongoing activity within this identified neural circuitry can contribute to an individual developing anxiety disorders.

    2016-01-01

    There is building evidence that highly socially anxious (HSA) individuals frequently avoid making eye contact, which may contribute to less meaningful social interactions and maintenance of social anxiety symptoms. However, research to date is lacking in ecological validity due to the usage of either static or pre-recorded facial stimuli or subjective coding of eye contact. The current study examined the relationships among trait social anxiety, eye contact avoidance, state anxiety, and participants' self-perceptions of interaction performance during a live, four-minute conversation with a confederate via webcam, and while being covertly eye-tracked. Participants included undergraduate women who conversed with same-sex confederates. Results indicated that trait social anxiety was inversely related to eye contact duration and frequency averaged across the four minutes, and positively related to state social anxiety and negative self-ratings. In addition, greater anticipatory state anxiety was associated with reduced eye contact throughout the first minute of the conversation. Eye contact was not related to post-task state anxiety or self-perception of poor performance; although, trends emerged in which these relations may be positive for HSA individuals. The current findings provide enhanced support for the notion that eye contact avoidance is an important feature of social anxiety. PMID:26677735

  3. State-dependent µ-opioid Modulation of Social Motivation – a model

    Guro Engvig Loseth

    2014-12-01

    Full Text Available Social mammals engage in affiliative interactions both when seeking relief from negative affect and when searching for pleasure and joy. These two motivational states are both modulated by µ-opioid transmission. The µ-opioid receptor (MOR system in the brain mediates pain relief and reward behaviours, and is implicated in social reward processing and affiliative bonding across mammalian species. However, pharmacological manipulation of the µ-opioid system has yielded opposite effects on rodents and primates: in rodents, social motivation is generally increased by MOR agonists and reduced by antagonists, whereas the opposite pattern has been shown in primates. Here, we address this paradox by taking into account differences in motivational state. We first review evidence for µ-opioid mediation of reward processing, emotion regulation, and affiliation in humans, non-human primates, rodents and other species. Based on the consistent cross-species similarities in opioid functioning, we propose a unified, state-dependent model for µ-opioid modulation of affiliation across the mammalian species. Finally, we show that this state-dependent model is supported by evidence from both rodent and primate studies, when species and age differences in social separation response are taken into account.

    Mental fatigue (MF) is commonly observed following prolonged cognitive activity and can have major repercussions on the daily life of patients as well as healthy individuals. Despite its important impact, the cognitive processes involved in MF remain largely unknown. An influential hypothesis states that MF does not arise from a disruption of overused neural processes but, rather, is caused by a progressive decrease in motivation-related task engagement. Here, to test this hypothesis, we measured various neural, autonomic, psychometric and behavioral signatures of MF and motivation (EEG, ECG, pupil size, eye blinks, Skin conductance responses (SCRs), questionnaires and performance in a working memory (WM) task) in healthy volunteers, while MF was induced by Sudoku tasks performed for 120 min. Moreover extrinsic motivation was manipulated by using different levels of monetary reward. We found that, during the course of the experiment, the participants' subjective feeling of fatigue increased and their performance worsened while their blink rate and heart rate variability (HRV) increased. Conversely, reward-induced EEG, pupillometric and skin conductance signal changes, regarded as indicators of task engagement, remained constant during the experiment, and failed to correlate with the indices of MF. In addition, MF did not affect a simple reaction time task, despite the strong influence of extrinsic motivation on this task. Finally, alterations of the motivational state through monetary incentives failed to compensate the effects of MF. These findings indicate that MF in healthy subjects is not caused by an alteration of task engagement but is likely to be the consequence of a decrease in the efficiency, or availability, of cognitive resources.

    K{sup }- nuclear optical potentials are constructed from in-medium K-bar N scattering amplitudes within a chirally motivated coupled-channel model. The strong energy and density dependence of the scattering amplitudes at and below threshold leads to K{sup }- potential depths -Re V{sub K{sup -}}({rho}{sub 0}) approx. 80 - 100 MeV. Self consistent calculations of K{sup }- nuclear quasi-bound states are discussed.

    Mental fatigue (MF) is commonly observed following prolonged cognitive activity and can have major repercussions on the daily life of patients as well as healthy individuals. Despite its important impact, the cognitive processes involved in MF remain largely unknown. An influential hypothesis states that MF does not arise from a disruption of overused neural processes but, rather, is caused by a progressive decrease in motivation-related task engagement. Here, to test this hypothesis, we meas...

    2011-05-01

    Using Monte Carlo simulations of a wormlike chain that contains the excluded-volume interaction, we demonstrate that a directionally anisotropic state exists at high surface coverage, when the chain is confined to a spherical surface. The isotropic-anisotropic transition has first-order characteristics and can be compared with the isotropic-nematic transition observed in lyotropic polymer systems, both driven by the excluded-volume interaction. Unlike a nematic state, the anisotropic state observed here displays the so-called tennis-ball conformation, coupling the polymer-segment orientation preference with positional order.

    Prezygotic isolation due to habitat choice is important to many models of speciation-with-gene-flow. Habitat choice is usually thought to occur through positive preferences of organisms for particular environments. However, avoidance of non-natal environments may also play a role in choice and have repercussions for post-zygotic isolation that preference does not. The recent host shift of Rhagoletis pomonella (Diptera: Tephritidae) from downy hawthorn, Crataegus mollis, to introduced apple, Malus domestica, in the eastern United States is a model for speciation-with-gene-flow. However, the fly is also present in the western United States where it was likely introduced via infested apples ≤ 60 years ago. R. pomonella now attacks two additional hawthorns in the west, the native C. douglasii (black hawthorn) and the introduced C. monogyna (English ornamental hawthorn). Flight tunnel tests have shown that western apple-, C. douglasii- and C. monogyna-origin flies all positively orient to fruit volatile blends of their respective natal hosts in flight tunnel assays. Here, we show that these laboratory differences translate to nature through field-trapping studies of flies in the state of Washington. Moreover, western R. pomonella display both positive orientation to their respective natal fruit volatiles and avoidance behaviour (negative orientation) to non-natal volatiles. Our results are consistent with the existence of behaviourally differentiated host races of R. pomonella in the west. In addition, the rapid evolution of avoidance behaviour appears to be a general phenomenon for R. pomonella during host shifts, as the eastern apple and downy hawthorn host races also are antagonized by non-natal fruit volatiles.

    2009-01-01

    The electric power system in the Western United States was simulated to evaluate the potential of solar photovoltaics (PV) in reducing fossil-fuel use and associated emissions. The simulations used a utility production cost model to evaluate a series of PV penetrations where up to 10% of the region's electricity is derived from PV. The analysis focused on California, which uses gas for a large fraction of its generation and Colorado, which derives most of its electricity from coal. PV displaces gas and electricity imports almost exclusively in California, with a displacement rate of about 6000-9000 kJ per kWh of PV energy generated. In Colorado, PV offsets mostly gas at low penetration, with increasing coal displacement during nonsummer months and at higher penetration. Associated reductions in CO2, NOx, and SO2 emissions are also calculated. PMID:19209611

    2016-02-01

    Many researches have been conducted in the area of control applied to vehicle dynamics, aiming at reducing the possibility of the occurrence of the type of accident known as rollover. In this research, based on a common nonlinear model and its linearisation, a method for properly selecting matrices for solving the Riccati equation considering different speeds was proposed. The method showed in which ways speed really influences the choice of controller gains. By developing the dynamic equations for the yaw- and roll-coupled motions and modelling of controllers and state observers, it is possible to compare the efficacy of this control strategy using both linear and nonlinear simulations using Matlab. Significant results were obtained regarding the reduction of the rollover coefficient for a double-lane change manoeuvre at different speeds, thus indicating advantages of using this controller in practical cases.

  14. Simulating Surfactant Spreading: Impact of a Physically Motivated Equation of State

    2016-01-01

    For more than two decades, a single model for the spreading of a surfactant-driven thin liquid film has dominated the applied mathematics literature on the subject. Recently, through the use of fluorescently-tagged lipids, it has become possible to make direct, quantitative comparisons between experiments and models. These comparisons have revealed two important discrepancies between simulations and experiments: the spatial distribution of the surfactant layer, and the timescale over which spreading occurs. In this paper, we present numerical simulations that demonstrate the impact of the particular choice of the equation of state (EoS) relating the surfactant concentration to the surface tension. Previous choices of the model EoS have been an ad-hoc decreasing function. Here, we instead propose an empirically-motivated equation of state; this provides a route to resolving some discrepancies and raises new issues to be pursued in future experiments. In addition, we test the influence of the choice of initial ...

    In the current study, we aimed to extend smoking cue-reactivity research by evaluating delay discounting as an outcome of cigarette cue exposure. We also separated introspection in response to cues (e.g., self-reporting craving and affect) from cue exposure alone, to determine if introspection changes behavioral responses to cigarette cues. Finally, we included measures of quit motivation and resistance to smoking to assess motivational influences on cue exposure. Smokers were invited to participate in an online cue-reactivity study. Participants were randomly assigned to view smoking images or neutral images, and were randomized to respond to cues with either craving and affect questions (e.g., introspection) or filler questions. Following cue exposure, participants completed a delay discounting task and then reported state affect, craving, and resistance to smoking, as well as an assessment of quit motivation. We found that after controlling for trait impulsivity, participants who introspected on craving and affect showed higher delay discounting, irrespective of cue type, but we found no effect of response condition on subsequent craving (e.g., craving reactivity). We also found that motivation to quit interacted with experimental conditions to predict state craving and state resistance to smoking. Although asking about craving during cue exposure did not increase later craving, it resulted in greater delaying of discounted rewards. Overall, our findings suggest the need to further assess the implications of introspection and motivation on behavioral outcomes of cue exposure. PMID:27115733

The survey questionsencompass the field of motivation for sport activity. The questionnaire consists of 23 statementsconcerning the motivation before and 25 statements concerning motivation during pregnancy.Individuals define their own motive for sport activity on the five-degree scale. We analyzed therepetition frequencies of all the motives in all three stages of pregnancy and established the crucialmotives for engaging in sport activities before and during pregnancy. Motivational structuresare relatively permanent structures of cognitive-conative area which begin to form in the earlychildhood; therefore we expect these chosen motives to appear in all stages. We ascertained thatpregnant women should be as much as possible acquainted with the influence and significance ofsport activity on their own and their child’s health and wellbeing since these are the leading motivesin all three stages of our measuring. Motives within motivational structure may change inspecific circumstances. This is established by our findings as well as during pregnancy the motivesof health of unborn child and positive influence of mother’s well being on child take highfrequencies of occurrence.

    Full Text Available Abstract Background Ensuring health worker job satisfaction and motivation are important if health workers are to be retained and effectively deliver health services in many developing countries, whether they work in the public or private sector. The objectives of the paper are to identify important aspects of health worker satisfaction and motivation in two Indian states working in public and private sectors. Methods Cross-sectional surveys of 1916 public and private sector health workers in Andhra Pradesh and Uttar Pradesh, India, were conducted using a standardized instrument to identify health workers' satisfaction with key work factors related to motivation. Ratings were compared with how important health workers consider these factors. Results There was high variability in the ratings for areas of satisfaction and motivation across the different practice settings, but there were also commonalities. Four groups of factors were identified, with those relating to job content and work environment viewed as the most important characteristics of the ideal job, and rated higher than a good income. In both states, public sector health workers rated "good employment benefits" as significantly more important than private sector workers, as well as a "superior who recognizes work". There were large differences in whether these factors were considered present on the job, particularly between public and private sector health workers in Uttar Pradesh, where the public sector fared consistently lower (P P Conclusion There are common areas of health worker motivation that should be considered by managers and policy makers, particularly the importance of non-financial motivators such as working environment and skill development opportunities. But managers also need to focus on the importance of locally assessing conditions and managing incentives to ensure health workers are motivated in their work.

    Using structural equation modeling techniques, this study examines causal models of driving avoidance and exposure among older adults. Prior studies have revealed that past incidence of falls, Useful Field of View (UFOV) test performance, and Trails Making test performance are predictive of subsequent motor vehicle crash involvement [Owsley, C., Ball, K., McGwin Jr., G., Sloane, M.E., Roenker, D.L., White, M.F., Overley, E.T., 1998. Visual processing impairment and risk of motor vehicle crash among older adults. J. Am. Med. Assoc. 279 (14), 1083-1088; Sims, R.V., McGwin, G., Pulley, L., Roseman, J.M., 2001.

Soc. 46, 854-861]. Data analyses used these indices, along with age, health, measures of physical functioning, and additional measures of cognitive functioning, to examine driving exposure and avoidance behaviors. A field sample of 4,234 drivers, 55 years of age and older, were recruited from the Maryland Motor Vehicles Administration after renewing their driver's licenses. A performance-based assessment, which included the Gross Impairment Screening battery and task 2 of the UFOV test, was completed by participants. A sub-sample of participants (n=815) were interviewed by telephone about their health and mobility 3-6 months following the initial assessment at a renewal center. In addition to age and gender, latent variables for health status, physical functioning, cognitive functioning, driving exposure, and driving avoidance were created. Direct and indirect causal paths were specified. Age, gender, health status, and cognitive functioning had direct effects on both driving exposure and driving avoidance; physical functioning did not have a direct effect on driving exposure or avoidance. The implications of these findings are discussed as they relate to designing

In this review, I give a comprehensive overview of the current state of Monte Carlo simulations of models of self-avoiding walks. The self-avoiding walk model is revisited, and the motivations for Monte Carlo simulations of this model are discussed. Efficient sampling of self-avoiding walks remains an elusive objective, but significant progress has been made over the last three decades. The model still poses challenging numerical questions however, and I review specific Monte Carlo methods for improved sampling including general Monte Carlo techniques such as Metropolis sampling, umbrella sampling and multiple Markov Chain sampling. In addition, specific static and dynamic algorithms for walks are presented, and I give an overview of recent innovations in this field, including algorithms such as flatPERM, flatGARM and flatGAS.

Interdependent self-construals were positively related and independent self-construals were negatively related to adoption of avoidance goals (Study 1), Asian Americans adopted more avoidance goals than non-Asian Americans (Study 2), andpersonsfrom South Korea and Russia adopted more avoidance goals than those in the United States (Studies 3 and 4, respectively). Studies 3 and 4 investigated andfound supportfor our secondary hypothesis that avoidance personal goals are a negative predictor of subjective well-being in individualistic (the United States), but not collectivistic (South Korea and Russia), countries. The findings are discussed in terms of other approach-avoidance constructs and motivational processes. PMID:11760139

    2004-01-01

    Responses from freshwater anglers (n = 4287) to a nationwide survey of the US fishing club members were used to assess differences in the importance of 16 fishing motivation items between 1987 and 1997, dates that preceded and followed a period of substantial decline in recreational fishing participation in the US. Comparison of respondents' motivations for fishing in 1997 and 10 years earlier indicated consistency in the paramount importance of being outdoors, relaxation and the experience of the catch. However, the importance of family recreation and being with friends in 1987 were replaced by escape items in 1997. Anglers with fewer dependents and living in areas with higher population density were more likely to decrease the importance of family recreation. Younger anglers were more likely to decrease the importance of being with friends. Anglers who had higher household income, fished more and had higher fishing expenditures were more likely to decrease the importance of obtaining fish to eat. The results of this study suggest that managers should be less concerned about angler opposition to liberal regulations that allow anglers to harvest fish, and that heightened efforts to recruit and retain recreational anglers, which presently focus on family recreation, should be broadened to include outdoor experience, relaxation and escape aspects of fishing. ?? 2004 Blackwell Publishing Ltd.

  20. Airborne Collision Detection and Avoidance for Small UAS Sense and Avoid Systems

    Science.gov (United States)

    Sahawneh, Laith Rasmi

    The increasing demand to integrate unmanned aircraft systems (UAS) into the national airspace is motivated by the rapid growth of the UAS industry, especially small UAS weighing less than 55 pounds. Their use however has been limited by the Federal Aviation Administration regulations due to collision risk they pose, safety and regulatory concerns. Therefore, before civil aviation authorities can approve routine UAS flight operations, UAS must be equipped with sense-and-avoid technology comparable to the see-and-avoid requirements for manned aircraft. The sense-and-avoid problem includes several important aspects including regulatory and system-level requirements, design specifications and performance standards, intruder detecting and tracking, collision risk assessment, and finally path planning and collision avoidance. In this dissertation, our primary focus is on developing an collision detection, risk assessment and avoidance framework that is computationally affordable and suitable to run on-board small UAS. To begin with, we address the minimum sensing range for the sense-and-avoid (SAA) system. We present an approximate close form analytical solution to compute the minimum sensing range to safely avoid an imminent collision. The approach is then demonstrated using a radar sensor prototype that achieves the required minimum sensing range. In the area of collision risk assessment and collision prediction, we present two approaches to estimate the collision risk of an encounter scenario. The first is a deterministic approach similar to those been developed for Traffic Alert and Collision Avoidance (TCAS) in manned aviation. We extend the approach to account for uncertainties of state estimates by deriving an analytic expression to propagate the error variance using Taylor series approximation. To address unanticipated intruders maneuvers, we propose an innovative probabilistic approach to quantify likely intruder trajectories and estimate the probability of

  2. Approach-avoidance activation without anterior asymmetry

    2014-03-01

    Full Text Available Occasionally, the expected effects of approach-avoidance motivation on anterior EEG alpha asymmetry fail to emerge, particularly in studies using affective picture stimuli. These null findings have been explained by insufficient motivational intensity of, and/or overshadowing interindividual variability within the responses to emotional pictures. These explanations were systematically tested using data from 70 students watching 5 types of affective pictures ranging from very pleasant to unpleasant. The stimulus categories reliably modulated self-reports as well as the amplitude of late positive potential, an ERP component reflecting orienting towards motivationally significant stimuli. The stimuli did not, however, induce expected asymmetry effects either for the sample or individual participants. Even while systematic stimulus-dependent individual differences emerged in self-reports as well as LPP amplitudes, the asymmetry variability was dominated by stimulus-independent interindividual variability. Taken together with previous findings, these results suggest that under some circumstances anterior asymmetry may not be an inevitable consequence of core affect. Instead, state asymmetry shifts may be overpowered by stable trait asymmetry differences and/or stimulus-independent yet situation-dependent interindividual variability, possibly caused by processes such as emotion regulation or anxious apprehension.

    Previous neuroscientific studies have shown that the dopaminergic system plays an important role in creative potential measured by divergent thinking (CPMDT), emotional control, and motivational state. However, although associations between two of these four components have been previously established (e.g., the association between CPMDT and emotional control, the association between CPMDT and motivational state, etc.), the interactions between these four remain unknown. The purpose of this study was to reveal these interactions using path analyses. The Taq1A polymorphism of the dopamine D2 receptor (DRD2) gene was used for this purpose. For measuring emotional intelligence (EI), we used the Japanese version of the Emotional Intelligence Scale. CPMDT was measured using the S-A creativity test. Motivational state was measured using the Vigor subscale of the Japanese version of the Profile of Mood Scale (POMS). Data from 766 healthy, right-handed individuals (426 men and 340 women; 20.7 ± 1.9 years of age) were used in this study. There were significant and robust positive relationships among measures of CPMDT, EI, and motivational state across sex. In addition, the polymorphism of the DRD2 gene was significantly associated with EI, specifically in females. Path analysis in females indicates that the model in which (a) the DRD2 polymorphism primarily facilitates EI, (b) EI in turn facilitates CPMDT and leads to a better motivational state, and (c) a better motivational state also directly facilitates CPMDT explains the data in the most accurate manner. This study suggested a comprehensive picture of the cascade of the associations among dopamine, EI, motivational state, and CPMDT at least in females. PMID:26217259

    Based on consumer socialization theory, this study proposes and tests a conceptual model of social media shopping behavior, which links the antecedents of user motivations of engagement and peer communication about products to shopping behavior through social media. A cross-cultural survey was conducted with social media users in two culturally distinct markets with the largest Internet population: China (n=304) and the United States (n=328). Findings showed that social interaction, information, and remuneration were positive antecedents of peer communication for users from both countries. Peer communication positively impacted social media shopping behavior, and cultural differences were observed, with social interaction being important to Chinese users' shopping behavior, while remuneration was more important to American users. Implications are discussed. PMID:26376370

  13. On the role of subsecond dopamine release in conditioned avoidance

    Directory of Open Access Journals (Sweden)

    Erik B Oleson

    2013-06-01

    Full Text Available Using shock avoidance procedures to study conditioned behavioral responses has a rich history within the field of experimental psychology. Such experiments led to the formulation of the general concept of negative reinforcement and specific theories attempting to explain escape and avoidance behavior, or why animals choose to either terminate or prevent the presentation of an aversive event. For example, the two-factor theory of avoidance holds that cues preceding an aversive event begin to evoke conditioned fear responses, and these conditioned fear responses reinforce the instrumental avoidance response. Current neuroscientific advances are providing new perspectives into this historical literature. Due to its well-established role in reinforcement processes and behavioral control, the mesolimbic dopamine system presented itself as a logical starting point in the search for neural correlates of avoidance and escape behavior. We recently demonstrated that phasic dopamine release events are inhibited by stimuli associated with aversive events but increased by stimuli preceding the successful avoidance of the aversive event. The latter observation is inconsistent with the second component of the two-factor theory of avoidance and; therefore, led us propose a new theoretical explanation of conditioned avoidance: 1 fear is initially conditioned to the warning signal and dopamine computes this fear association as a decrease in release, 2 the warning signal, now capable of producing a negative emotional state, suppresses dopamine release and behavior, 3 over repeated trials the warning signal becomes associated with safety rather than fear; dopaminergic neurons already compute safety as an increase in release and begin to encode the warning signal as the earliest predictor of safety 4 the warning signal now promotes conditioned avoidance via dopaminergic modulation of the brain’s incentive-motivational circuitry.

  15. Motivating Workers in Construction

    2014-01-01

    Full Text Available The study of the motivation of construction workers is limited to a relatively small body of knowledge. Although there is considerable research available regarding motivation and productivity, few researchers have provided a comprehensive analysis on the motivation of construction workers. The research stated that productivity in construction has not improved compared to other industry sectors such as manufacturing. This trend has been echoed in publications throughout the past five decades, and suggested that motivation is one of the key factors impacting productivity. This paper offers a comprehensive review of the published work that directly links the key words—construction and motivation. The findings have been presented in five themes, that is, motivation models, environment and culture, incentives and empowerment, and worker management. This paper concludes with two methods suggested by previous researchers to improve motivation of construction workers: (1 relevant worker incentives (intrinsic or extrinsic and (2 improved management practices, specifically regarding communication with workers.

    Full Text Available Event-related potentials (ERPs and other electroencephalographic (EEG evidence show that frontal brain areas of higher and lower socioeconomic status (SES children are recruited differently during selective attention tasks. We assessed whether multiple variables related to self-regulation (perceived mental effort emotional states (e.g., anxiety, stress, etc. and motivational states (e.g., boredom, engagement, etc. may co-occur or interact with frontal attentional processing probed in two matched-samples of fourteen lower-SES and higher-SES adolescents. ERP and EEG activation were measured during a task probing selective attention to sequences of tones. Pre- and post-task salivary cortisol and self-reported emotional states were also measured. At similar performance level, the higher-SES group showed a greater ERP differentiation between attended (relevant and unattended (irrelevant tones than the lower-SES group. EEG power analysis revealed a cross-over interaction, specifically, lower-SES adolescents showed significantly higher theta power when ignoring rather than attending to tones, whereas, higher-SES adolescents showed the opposite pattern. Significant theta asymmetry differences were also found at midfrontal electrodes indicating left hypo-activity in lower-SES adolescents. The attended vs. unattended difference in right midfrontal theta increased with individual SES rank, and (independently from SES with lower cortisol task reactivity and higher boredom. Results suggest lower-SES children used additional compensatory resources to monitor/control response inhibition to distracters, perceiving also more mental effort, as compared to higher-SES counterparts. Nevertheless, stress, boredom and other task-related perceived states were unrelated to SES. Ruling out presumed confounds, this study confirms the midfrontal mechanisms responsible for the SES effects on selective attention reported previously and here reflect genuine cognitive

    The role of dopaminergic brain regions in avoidance behaviour is unclear. Active avoidance requires motivation, and the latter is linked to increased activity in dopaminergic regions. However, avoidance is also often tethered to the prospect of punishment, a state typically characterized by below baseline levels of dopaminergic function. Avoidance has been considered from the perspective of two-factor theories where the prospect of safety is considered to act as a surrogate for reward, leading to dopamine release and enhanced motivational drive. Using fMRI we investigated predictions from two-factor theory by separating the neural representation of a conventional net expected value, which is negative in the case of avoidance, from an adjusted expected value which factors in a possibility of punishment and is larger for both big rewards and big (predictably avoidable) punishments. We show that neural responses in ventral striatum and ventral tegmental area/substantial nigra (VTA/SN) covaried with net expected value. Activity in VTA/SN also covaried with an adjusted expected value, as did activity in anterior insula. Consistent with two-factor theory models, the findings indicate that VTA/SN and insula process an adjusted expected value during avoidance behaviour. PMID:27132047

    Full Text Available Background and Objectives: Cannabinoids are a class of psychoactive compounds that produce a wide array of effects in a large number of species. In the present study, the effects of bilateral intra-CA1 injections of an α2-adrenergic receptor agents, on WIN55,212-2 state-dependent learning were examined in adult male Wistar rats. Methods: The animals were bilaterally implanted with chronic cannulae in the CA1 regions of the dorsal hippocampus, trained in a step-down type inhibitory avoidance task, and tested 24h after training to measure step-down latency.Results: Post-training intra-CA1 injection of WIN55,212-2 (0.25 and 0.5µg/rat induced impairment of memory retention. Amnesia produced by post-training WIN55,212-2 (0.5µg/rat was reversed by pre-test administration of the same dose of WIN55,212-2 that is due to a state-dependent effect. Pre-test intra-CA1 injection of clonidine (0.5 and 0.75µg/rat, intra-CA1 improved post-training WIN55,212-2 (0.5µg/rat, intra-CA1-induced retrieval impairment, while pre-test intra-CA1 injection of yohimbine (1µg/rat, intra-CA1 2min before the administration of WIN55,212-2 (0.5µg/rat, intra-CA1 inhibited WIN55,212-2 state-dependent memory. Conclusion: These results suggest that α2-adrenergic receptors of the dorsal hippocampal CA1 regions may play an important role in Win55,212-2-induced amnesia and WIN55,212-2 state-dependent memory.

    Although motivation is a well-established field of study in its own right, and has been fruitfully studied in connection with attribution theory and belief formation under the heading of "motivated thinking," its powerful and pervasive influence on specifically explanatory processes is less well explored. Where one has a strong motivation to understand some event correctly, one is thereby motivated to adhere as best one can to normative or "epistemic" criteria for correct or accurate explanation, even if one does not consciously formulate or apply such criteria. By contrast, many of our motivations to explain introduce bias into the processes involved in generating, evaluating, or giving explanations. Non-epistemic explanatory motivations, or following Kunda's usage, "directional" motivations, include self-justification, resolution of cognitive dissonance, deliberate deception, teaching, and many more. Some of these motivations lead to the relaxation or violation of epistemic norms; others enhance epistemic motivation, so that one engages in more careful and thorough generational and evaluative processes. We propose that "real life" explanatory processes are often constrained by multiple goals, epistemic and directional, where these goals may mutually reinforce one another or may conflict, and where our explanations emerge as a matter of weighing and satisfying those goals. We review emerging evidence from psychology and neuroscience to support this framework and to elucidate the central role of motivation in human thought and explanation. PMID:26528166

    Full Text Available Purpose: to determine the motivation of employees of structural subdivisions of the State Emergency Service of Ukraine to improve their level of professional competence by means of physical training. Material: questionnaire survey of 130 rescue workers aged 25 to 40 years. Results: the main motives of rescue team personnel for physical culture and sports activities are gain in physical health and professional competence, while performing rescue missions. It was established that, when on duty, most of the firefighters and rescue workers are not engaged in physical exercise at all; household chores and poor state of health in case of men prevent rescue team employees from doing exercises outside of working hours. It was found that fire-rescue specialists give preference to the development of muscle strength during professional physical trainings and would like to perform power exercises. Conclusions: the low level of motivation of current fire-rescue workers for physical self-improvement requires optimization of control over professional physical education in departments of the State Emergency Service of Ukraine.

In short, “real life” explanatory processes are often constrained by multiple goals, epistemic and directional, where these goals may mutually reinforce one another or may conflict, and where our explanations emerge as a matter of weighing and satisfying those goals. Our proposals are largely programmatic, although we do review a good deal of relevant behavioral and neurological evidence. Specifically, we recognize five generative processes, some of which cover further sub-processes, and six evaluative processes. All of these are potential points of entry for the influence of motivation. We then suggest in some detail how specific sorts of explanatory motivation interact with specific explanatory processes.

    Elevated levels of fear and avoidance are core symptoms across the anxiety disorders. It has long been known that fear serves to motivate avoidance. Consequently, fear extinction has been the primary focus in pre-clinical anxiety research for decades, under the implicit assumption that removing the motivator of avoidance (fear) would automatically mitigate the avoidance behaviors as well. Although this assumption has intuitive appeal, it has received little scientific scrutiny. The scarce evi...

  19. Recurrent, robust and scalable patterns underlie human approach and avoidance.

    Directory of Open Access Journals (Sweden)

    Full Text Available BACKGROUND: Approach and avoidance behavior provide a means for assessing the rewarding or aversive value of stimuli, and can be quantified by a keypress procedure whereby subjects work to increase (approach, decrease (avoid, or do nothing about time of exposure to a rewarding/aversive stimulus. To investigate whether approach/avoidance behavior might be governed by quantitative principles that meet engineering criteria for lawfulness and that encode known features of reward/aversion function, we evaluated whether keypress responses toward pictures with potential motivational value produced any regular patterns, such as a trade-off between approach and avoidance, or recurrent lawful patterns as observed with prospect theory. METHODOLOGY/PRINCIPAL FINDINGS: Three sets of experiments employed this task with beautiful face images, a standardized set of affective photographs, and pictures of food during controlled states of hunger and satiety. An iterative modeling approach to data identified multiple law-like patterns, based on variables grounded in the individual. These patterns were consistent across stimulus types, robust to noise, describable by a simple power law, and scalable between individuals and groups. Patterns included: (i a preference trade-off counterbalancing approach and avoidance, (ii a value function linking preference intensity to uncertainty about preference, and (iii a saturation function linking preference intensity to its standard deviation, thereby setting limits to both. CONCLUSIONS/SIGNIFICANCE: These law-like patterns were compatible with critical features of prospect theory, the matching law, and alliesthesia. Furthermore, they appeared consistent with both mean-variance and expected utility approaches to the assessment of risk. Ordering of responses across categories of stimuli demonstrated three properties thought to be relevant for preference-based choice, suggesting these patterns might be grouped together as a

  20. Understanding motivational structures that differentially predict engagement and achievement in middle school science

    Middle school has been documented as the period in which a drop in students' science interest and achievement occurs. This trend indicates a lack of motivation for learning science; however, little is known about how different aspects of motivation interact with student engagement and science learning outcomes. This study examines the relationships among motivational factors, engagement, and achievement in middle school science (grades 6-8). Data were obtained from middle school students in the United States (N = 2094). The theoretical relationships among motivational constructs, including self-efficacy, and three types of goal orientations (mastery, performance approach, and performance avoid) were tested. The results showed that motivation is best modeled as distinct intrinsic and extrinsic factors; lending evidence that external, performance based goal orientations factor separately from self-efficacy and an internal, mastery based goal orientation. Second, a model was tested to examine how engagement mediated the relationships between intrinsic and extrinsic motivational factors and science achievement. Engagement mediated the relationship between intrinsic motivation and science achievement, whereas extrinsic motivation had no relationship with engagement and science achievement. Implications for how classroom practice and educational policy emphasize different student motivations, and in turn, can support or hinder students' science learning are discussed.

    Full Text Available Abstract Background Rule violations among elite-level sports competitors and tragedies among adolescents have largely defined the issue of non-medical anabolic-androgenic steroid (NMAAS use for the public and policy makers. However, the predominant and oft-ignored segment of the NMAAS community exists in the general population that is neither participating in competitive sports nor adolescent. A clearer profile of NMAAS users within the general population is an initial step in developing a full understanding of NMAAS use and devising appropriate policy and interventions. This survey sought to provide a more comprehensive profile of NMAAS users by accessing a large sample of user respondents from around the United States. Methods U.S.-based male NMAAS users (n = 1955 were recruited from various Internet websites dedicated to resistance training activities and use of ergogenic substances, mass emails, and print media to participate in a 291-item web-based survey. The Internet was utilized to provide a large and geographically diverse sample with the greatest degree of anonymity to facilitate participation. Results The majority of respondents did not initiate AAS use during adolescence and their NMAAS use was not motivated by athletics. The typical user was a Caucasian, highly-educated, gainfully employed professional approximately 30 years of age, who was earning an above-average income, was not active in organized sports, and whose use was motivated by increases in skeletal muscle mass, strength, and physical attractiveness. These findings question commonly held views of the typical NMAAS user and the associated underlying motivations. Conclusion The focus on "cheating" athletes and at risk youth has led to ineffective policy as it relates to the predominant group of NMAAS users. Effective policy, prevention or intervention should address the target population(s and their reasons for use while utilizing their desire for responsible use and

    Full Text Available The amygdala has traditionally been associated with fear, mediating the impact of negative emotions on memory. However, this view does not fully encapsulate the function of the amygdala, nor the impact that processing in this structure has on the motivational limbic corticostriatal circuitry of which it is an important structure. Here we discuss the interactions between different amygdala nuclei with cortical and striatal regions involved in motivation; interconnections and parallel circuitries that have become increasingly understood in recent years. We review the evidence that the amygdala stores memories that allow initially motivationally neutral stimuli to become associated through pavlovian conditioning with motivationally relevant outcomes which, importantly, can be either appetitive (e.g. food or aversive (e.g. electric shock. We also consider how different psychological processes supported by the amygdala such as conditioned reinforcement and punishment, conditioned motivation and suppression, and conditioned approach and avoidance behavior, are not only psychologically but also neurobiologically dissociable, being mediated by distinct yet overlapping neural circuits within the limbic corticostriatal circuitry. Clearly the role of the amygdala goes beyond encoding aversive stimuli to also encode the appetitive, requiring an appreciation of the amygdala’s mediation of both appetitive and fearful behavior through diverse psychological processes.

    This study examined alternative seven-, five-, and three-factor structures for the Academic Motivation Scale, with data from a large convenience sample of 2,078 students matriculating in various business courses at three AACSB-accredited regional comprehensive universities. In addition, the invariance of the scale's factor structure between male and female students and between undergraduate and Master's of Business Administration students was investigated. Finally, the internal consistency of the items loading on each of the seven AMS subscales was assessed as well as whether the correlations among the subscales supported a continuum of self-determination. Results for the full sample as well as the targeted subpopulations supported the seven factor configuration of the scale with adequate model fit achieved for all but the MBA student group. The data also generated acceptable internal consistency statistics for all of the subscales. However, in line with a number of previous studies, the correlations between subscales failed to fully support the scale's simplex structure as proposed by self-determination theory. PMID:20524531

    2016-06-01

    Motivation has long been recognized as an important component of how people both differ from, and are similar to, each other. The current research applies the biologically grounded fundamental social motives framework, which assumes that human motivational systems are functionally shaped to manage the major costs and benefits of social life, to understand individual differences in social motives. Using the Fundamental Social Motives Inventory, we explore the relations among the different fundamental social motives of Self-Protection, Disease Avoidance, Affiliation, Status, Mate Seeking, Mate Retention, and Kin Care; the relationships of the fundamental social motives to other individual difference and personality measures including the Big Five personality traits; the extent to which fundamental social motives are linked to recent life experiences; and the extent to which life history variables (e.g., age, sex, childhood environment) predict individual differences in the fundamental social motives. Results suggest that the fundamental social motives are a powerful lens through which to examine individual differences: They are grounded in theory, have explanatory value beyond that of the Big Five personality traits, and vary meaningfully with a number of life history variables. A fundamental social motives approach provides a generative framework for considering the meaning and implications of individual differences in social motivation.

Metodología: se analizó la información sobre mortalidad del Sistema Nacional de Información en Salud (sinais. La unidad de análisis fue la causa básica de la defunción codificada según la décima revisión de la CIE. La mortalidad evitable fue clasificada según el catálogo de causas de muerte propuesto por Gómez. Se hizo un análisis exploratorio de la relación entre la mortalidad evitable y la derechohabiencia y el nivel socioeconómico de los municipios correspondientes a las muertes. Resultados: la tasa de mortalidad evitable global fue de 350,2 muertes por mil habitantes en la región. La mortalidad evitable por diagnóstico y tratamiento médico precoz, violencia y VIH/SIDA tuvo tasas de 223, 60 y 5 por mil habitantes, respectivamente, presentando variaciones de magnitud, sociodemográficas y por derechohabiencia entre estados. Discusión y conclusiones: las poblaciones de los estados de la frontera norte de México se caracterizan por tener una dinámica sociodemográfica y de los servicios de salud muy intensa. Los resultados sugieren que el sistema de salud está siendo rebasado en su respuesta a una alta frecuencia de enfermedades no transmisibles. En el aspecto social existen condiciones estructurales en México que favorecen la presencia de narcotráfico y su consecuente causa de violencia y consumo de drogas ilegales que podrían estar relacionadas con la frecuencia de muertes violentas y en forma subsidiaria con las causadas por el VIH/SIDA. / ABSTRACT Objective: to analyze avoidable mortality between 1998 and 2007 in the border states of Northern Mexico to evaluate, indirectly, the quality of the region's health care services.

  14. Avoiding congestion in recommender systems

    International Nuclear Information System (INIS)

    Recommender systems use the historical activities and personal profiles of users to uncover their preferences and recommend objects. Most of the previous methods are based on objects’ (and/or users’) similarity rather than on their difference. Such approaches are subject to a high risk of increasingly exposing users to a narrowing band of popular objects. As a result, a few objects may be recommended to an enormous number of users, resulting in the problem of recommendation congestion, which is to be avoided, especially when the recommended objects are limited resources. In order to quantitatively measure a recommendation algorithm's ability to avoid congestion, we proposed a new metric inspired by the Gini index, which is used to measure the inequality of the individual wealth distribution in an economy. Besides this, a new recommendation method called directed weighted conduction (DWC) was developed by considering the heat conduction process on a user–object bipartite network with different thermal conductivities. Experimental results obtained for three benchmark data sets showed that the DWC algorithm can effectively avoid system congestion, and greatly improve the novelty and diversity, while retaining relatively high accuracy, in comparison with the state-of-the-art methods.

    Commonality in etiology and clinical expression plus high comorbidity between pathological gambling and substance use disorders suggest common underlying motives. It is important to understand common motivators and differentiating factors. An overarching framework of addiction was used to examine predictors of problem gambling in current electronic gaming machine (EGM) gamblers. Path analysis was used to examine the relationships between antecedent factors (stressors, coping habits, social support), gambling motivations (avoidance, accessibility, social) and gambling behavior. Three hundred and forty seven (229 females: M = 29.20 years, SD = 14.93; 118 males: M = 29.64 years, SD = 12.49) people participated. Consistent with stress, coping and addiction theory, situational life stressors and general avoidance coping were positively related to avoidance-motivated gambling. In turn, avoidance-motivated gambling was positively related to EGM gambling frequency and problems. Consistent with exposure theory, life stressors were positively related to accessibility-motivated gambling, and accessibility-motivated gambling was positively related to EGM gambling frequency and gambling problems. These findings are consistent with other addiction research and suggest avoidance-motivated gambling is part of a more generalized pattern of avoidance coping with relative accessibility to EGM gambling explaining its choice as a method of avoidance. Findings also showed social support acted as a direct protective factor in relation to gambling frequency and problems and indirectly via avoidance and accessibility gambling motivations. Finally, life stressors were positively related to socially motivated gambling but this motivation was not related to either social support or gambling behavior suggesting it has little direct influence on gambling problems.

    We have used functional magnetic resonance imaging to study the neural correlates of motivation, concentrating on the motivation to learn and gain monetary rewards. We compared the activation in the brain obtained during reported high states of motivation for learning, with the ones observed when the motivation was based on monetary reward. Our results show that motivation to learn correlates with bilateral activity in the putamen, and that the higher the reported motivation, as derived from a questionnaire that each subject filled prior to scanning, the greater the change in the BOLD signals within the putamen. Monetary motivation also activated the putamen bilaterally, though the intensity of activity was not related to the monetary reward. We conclude that the putamen is critical for motivation in different domains and the extent of activity of the putamen may be pivotal to the motivation that drives academic achievement and thus academic successes.

    Associative conditioning of satiety indicates that concentrated maltodextrin (cMD) may induce a mildly aversive visceral signal within 20 min of its ingestion, as well as satiating normally. Individuals' awareness of this adverse state was tested on ratings of statistically distinct descriptions of factors liable to suppress hunger, whether distressing or comfortably satisfying. Wanted amount of a food and the pleasantness of eating it correlated highly for each of five foods, once again refuting the widespread presumption that "pleasant" refers to sensory pleasure; hence, as in previous reports, suppression of hunger was measured as a reduction of the averaged pleasantness of functionally related foods. At 20 min after the start of ingestion of a small meal on a near-empty stomach, cMD reliably reduced hunger. The greatest influence on hunger, besides normal sating, was thirst, but there were also tendencies to nausea and bloat, although all less than after a full sized meal. Visceral processes shortly after a meal can create dissociable conscious states, only one of which is satiety for food. PMID:21118700

    Research has shown that brain functions are realized by simultaneous oscillations in various frequency bands. In addition to examining oscillations in pre-specified bands, interactions and relations between the different frequency bandwidths is another important aspect that needs to be considered in unraveling the workings of the human brain and its functions. In this review we provide evidence that studying interdependencies between brain oscillations may be a valuable approach to study the electrophysiological processes associated with motivation and emotional states. Studies will be presented showing that amplitude-amplitude coupling between delta-alpha and delta-beta oscillations varies as a function of state anxiety and approach-avoidance-related motivation, and that changes in the association between delta-beta oscillations can be observed following successful psychotherapy. Together these studies suggest that cross-frequency coupling of brain oscillations may contribute to expanding our understanding of the neural processes underlying motivation and emotion.

  7. Avoidable waste management costs

    International Nuclear Information System (INIS)

    This report describes the activity based costing method used to acquire variable (volume dependent or avoidable) waste management cost data for routine operations at Department of Energy (DOE) facilities. Waste volumes from environmental restoration, facility stabilization activities, and legacy waste were specifically excluded from this effort. A core team consisting of Idaho National Engineering Laboratory, Los Alamos National Laboratory, Rocky Flats Environmental Technology Site, and Oak Ridge Reservation developed and piloted the methodology, which can be used to determine avoidable waste management costs. The method developed to gather information was based on activity based costing, which is a common industrial engineering technique. Sites submitted separate flow diagrams that showed the progression of work from activity to activity for each waste type or treatability group. Each activity on a flow diagram was described in a narrative, which detailed the scope of the activity. Labor and material costs based on a unit quantity of waste being processed were then summed to generate a total cost for that flow diagram. Cross-complex values were calculated by determining a weighted average for each waste type or treatability group based on the volume generated. This study will provide DOE and contractors with a better understanding of waste management processes and their associated costs. Other potential benefits include providing cost data for sites to perform consistent cost/benefit analysis of waste minimization and pollution prevention (WMIN/PP) options identified during pollution prevention opportunity assessments and providing a means for prioritizing and allocating limited resources for WMIN/PP

  8. The ventral hippocampus, but not the dorsal hippocampus is critical for learned approach-avoidance decision making.

    The resolution of an approach-avoidance conflict induced by ambivalent information involves the appraisal of the incentive value of the outcomes and associated stimuli to orchestrate an appropriate behavioral response. Much research has been directed at delineating the neural circuitry underlying approach motivation and avoidance motivation separately. Very little research, however, has examined the neural substrates engaged at the point of decision making when opposing incentive motivations are experienced simultaneously. We hereby examine the role of the dorsal and ventral hippocampus (HPC) in a novel approach-avoidance decision making paradigm, revisiting a once popular theory of HPC function, which posited the HPC to be the driving force of a behavioral inhibition system that is activated in situations of imminent threat. Rats received pre-training excitotoxic lesions of the dorsal or ventral HPC, and were trained to associate different non-spatial cues with appetitive, aversive and neutral outcomes in three separate arms of the radial maze. On the final day of testing, a state of approach-avoidance conflict was induced by simultaneously presenting two cues of opposite valences, and comparing the time the rats spent interacting with the superimposed 'conflict' cue, and the neutral cue. The ventral HPC-lesioned group showed significant preference for the conflict cue over the neutral cue, compared to the dorsal HPC-lesioned, and control groups. Thus, we provide evidence that the ventral, but not dorsal HPC, is a crucial component of the neural circuitry concerned with exerting inhibitory control over approach tendencies under circumstances in which motivational conflict is experienced. © 2015 Wiley Periodicals, Inc.

    CrossFit is a growing fitness trend in the United States; however, little systematic research has addressed specific motivational principles within this unique exercise environment. The purpose of the study was to explore the influence of gender and membership time on perceptions of motivational climate and goals within the CrossFit environment. Specifically, people may set goals related to self-improvement (i.e., mastery) or focus on their performance in comparison to others (i.e., performance). Motivational climate refers to an individual's perception of being encouraged to focus on either mastery or performance goals from CrossFit trainers. A total of 144 members (88 females; 56 males) completed questionnaires to assess participants' perceptions of CrossFit goal structures and perceptions of the motivational climate encouraged by the trainer within their CrossFit box. Results indicated a significant main effect for gender on preferred goals (p ≤ 0.05), with males reporting higher levels of performance approach goals and females reporting higher levels of master avoidance goals. Participants who reported shorter membership times were found to have significantly higher mastery-related goals than individuals who reported longer membership times (p ≤ 0.05). The results from the study suggest that practitioners should consider how perceptions of the motivational climate and goals in group-based exercise settings such as CrossFit may vary based on demographic variables, and that these differences may impact how to most effectively motivate, encourage, and instruct group members, particularly with regard to helping members set goals that most effectively address their approach to the CrossFit regimen.

    Adolescents who experience pain often face competing goals and have to choose whether to approach (confront) or avoid pain. This study investigates the decisions adolescents make when their pain conflicts with a valued goal. Adolescents between the ages of 15 and 18 years (N = 170) completed questionnaires on general and pain-specific anxiety, courage, and dispositional avoidance. Adolescents were presented with 16 vignettes (8 high pain intensity, 8 low pain intensity), which described pain conflicting with a goal (eg, doing well at school, seeing friends). Adolescents rated goals for importance and reported how likely they would be to approach or avoid each pain. Adolescents were more likely to avoid and were more fearful of high pain intensity than low pain intensity vignettes. Pain anxiety predicted higher levels of avoidance for both pain intensities. General anxiety was not a significant predictor of avoidance for either pain intensity. Goal importance promoted approach of goals, but only when pain was described as intense. However, pain anxiety predicted avoidance beyond the importance of goals for high pain intensity vignettes. In addition, we compared approach-avoidance of adolescents with and without chronic pain; analyses revealed no differences in approach-avoidance behaviour. We also found that behavioural endurance was predictive of approach and dispositional avoidance predicted higher avoidance, but courage was not predictive of behaviour in this task. We adopt a motivational perspective when interpreting the findings and consider whether the fear-avoidance model should be extended to include the function of avoidance or approach in the pursuit of a desired goal.

    2007-04-01

    How does a large multinational keep thousands of employees, operating in hundreds of countries, honest in a high-pressure business environment? As the chief legal officer at General Electric for nearly 20 years, Ben Heineman was part of the senior management group that sought to do just that--to make sure its executives and employees are moved to do the right thing as strongly as they are motivated to make their numbers. Heineman describes a set of systems that combine the communication of clear expectations with oversight, deterrence, and incentives. Nowhere are the expectations higher--and the sanctions more powerful--than for top executives. Heineman recounts example after example of senior leaders terminated for ethical lapses even when the business consequences of doing so were painful--and even when they had no direct knowledge of the violations occurring on their watch. To make expectations clear throughout the company, GE has systematically sought to set uniform standards that stay well ahead of current legal developments and stakeholders' changing attitudes about corporate accountability. Responsibility for implementing those standards, which are embedded in GE's operating practices, rests with the business leaders in the field. Oversight is both methodical and multifaceted. A host of auditing and assessment systems enables GE to compare the performance of its various business units against one another and against industry benchmarks. Perhaps the most powerful is the company's ombudsman system, which doesn't just allow but requires employees to lodge concerns. Failures to report into the system or up the line, or retaliation in any form, are firing offenses. The current intense focus on board-level governance has missed the point, Heineman argues. It is time to shift the debate from board oversight of the CEO to how top company leaders can most effectively infuse integrity at all levels of the corporation. PMID:17432157

Yoemans, ``Asteroid 2011 AG5 - A Reality Check,'' NASA-JPL, 2012) In 2011, The author say: the dark hole will take the dark comet to impact our solar system in 20 years, and give a systemic model between the sun and its companion-dark hole to explain why were there periodicity mass extinction on earth. (see Dayong Cao, BAPS.2011.CAL.C1.7, BAPS.2011.DFD.LA.24, BAPS.2012.APR.K1.78 and BAPS.2011.APR.K1.17) The dark Asteroid 2011 AG5 (as a dark comet) is made of the dark matter which has a space-time (as frequence-amplitude square) center- a different systemic model from solar systemic model. It can asborb the space-time and wave. So it is ``dark.'' When many dark matters hit on our earth, they can break our atom structure and our genetic code to trigger the Mass Extinction. In our experiments, consciousness can change the systematic model and code by a life-informational technology. So it can change the output signals of the solar cell. (see Dayong Cao, BAPS.2011.MAR.C1.286 and BAPS.2012.MAR.P33.14) So we will develop the genetic code of lives to evolution and sublimation, will use the dark matter to change the systemic model between dark hole and sun and will avoid next extinction.

    How do you motivate students to do their homework? Some instructors make students' homework scores a significant percentage of the final course grade. In that case, how much course credit is required? Some instructors do not grade homework at all, instead relying on students' intrinsic motivation to learn the course material. Will this actually work? Some instructors might motivate students by having quiz and/or exam problems closely match the assigned homework problems. In this article, we report on the effectiveness of grade incentives, homework-based quiz problems, and intrinsic motivation for 16 semesters of introductory mechanics and introductory electricity and magnetism (E&M) courses at the United States Air Force Academy (USAFA) between fall 2008 and spring 2012.

    近年来,大多数国有企业对知识型员工的激励普遍存在着激励方式滞后、激励手段匮乏等问题,引起知识型员工的管理成本上升、知识型员工跳槽频繁等不良现象的产生。所以,对知识型员工进行有效激励,激发知识型员工的积极性,发挥知识型员工的潜力,成为了目前很多企业的重要任务。通过问卷调查,分析国有企业知识型员工的激励问题,根据KANO模型数据分析员工满意度,将企业知识型员工的激励对策分为急需改进的因素和有待进一步解决的因素。%recent years, the majority of enterprises have problems of backward motivation patterns and lack of incentive methods to knowledge workers, giving rise to undesirable phenomena as increase in administrative cost and frequent job - hopping of them. As a result, how can organizations proceed with effective incentive, give full play to knowledge workers'initiative and fulfill their potential becomes the top priority of many companies. The arti- cle investigates the knowledge - based employee incentive problems of state - owned enterprises, according to ques- tionnaires and KANO model data analysis, in order to measure employee satisfaction. The article divides enterprise knowledge workers incentive countermeasure into factors in urgent need of improvement and factors to be further solved, with a view to investigate the problem of incentive system of corporation .

    Faries, Mark D; Kephart, Wesley; Jones, Eric J

    2015-01-01

    Two motivational systems underlie behaviour and affective responses - an inhibition/avoidance system and an activation/approach system. The purpose of the present study was to explore if individual differences in these motivational systems would occur in response to common weight and body composition testing within a sample of young, adult women. Electroencephalogram was used to distinguish approach or avoidance orientations via frontal asymmetry before and after testing sessions. Clear distinctions in motivational response were found, with 65% of the sample responding with an approach motivation, while 35% responded with an avoidance motivation. Even though all participants, on average, experienced a negative affective response, only the avoidance group self-reported a subsequent increase in "comfort food" consumption of desserts and snacks the week following the testing session. As shown with other stressors, clear individual differences exist in motivational responses to common weight and body composition testing. Such testing produces a general negative affective response; however, the individual differences in motivational responses might produce different behavioural choices. Future research and interventions in health communication should be considerate to this variation in motivational responses to help explain changes in both healthy and unhealthy behaviours following interactions involving one's body weight and/or body composition.

    In humans, optimism is a cognitive construct related to motivation; optimists exert effort, whereas pessimists disengage from effort. In this study, using a recently developed ambiguous-cue interpretation (ACI) paradigm we took the unique opportunity to investigate whether "optimism" as a trait is correlated with motivation in rodents. In a series of ACI tests (cognitive bias screening, CBS), we identified rats displaying "pessimistic" and "optimistic" traits. Subsequently, we investigated the trait differences in the motivation of these rats to gain reward and to avoid punishment using a progressive ratio (PR) schedule of reinforcement paradigm. Although "optimistic" and "pessimistic" animals did not differ in their motivation to avoid punishment, the "optimistic" rats were significantly more motivated to gain reward than their "pessimistic" conspecifics. For the first time, we showed an association between cognitive judgment bias and motivation in an animal model. Because both investigated processes are closely related to mental health and wellbeing, our results may be valuable for preclinical modeling of many psychiatric disorders. PMID:25762910

It reveals the meaning of social creativity as an individual social integrative capacity. The paper describes the component fullness of the person’s social creativity, which includes the following components: cognitive, motivational, communicative individual. It analyses in details the structure of the motivational component of social creativity, confirmed by factorial study. The study reveals the essence of the motivational component of social creativity in the unity of the internal and external motives, namely the desire for self-actualization and selfdevelopment, focusing on communication and interaction. It analyses the concept of "motivational profile of an individual". The article depicts the procedure of the empirical study organization which was held in two stages, on the basis of the Amur State University, The first step is the selection of students with the upperintermediate level of social creativity. As a result, after the selection of the respondents with an appropriate level of social creativity 62 subjects were taken into account for further study. During the second phase of the study it was carried out an analysis of ordinary (everyday and educational profiles in the "ideal" and "real" state of the social motives of creative students on the basis of Milman V.E. methods. The results of the profiles comparative analysis in the "ideal" and "real" state of motives let us talk about the dominating motive of communication in ordinary (everyday and educational spheres. Differentiation of motivational factors is characteristic for socially creative personality: supporting and consuming motives are shown in everyday sphere and developing motives dominate in educational sphere. The generalization of the empirical research results has revealed an impulsive type of a profile, which is characteristic for the motivational structure of a socially

  18. The Feasibility of Avoiding Future Climate Impacts: Results from the AVOID Programmes

    2014-12-01

    The AVOID programme and its successor, AVOID2, have focused on answering three core questions: how do we characterise potentially dangerous climate change and impacts, which emissions pathways can avoid at least some of these impacts, and how feasible are the future reductions needed to significantly deviate from a business-as-usual future emissions pathway. The first AVOID project succeeded in providing the UK Government with evidence to inform its position on climate change. A key part of the work involved developing a range of global emissions pathways and estimating and understanding the corresponding global impacts. This made use of a combination of complex general circulation models, simple climate models, pattern-scaling and state-of-the art impacts models. The results characterise the range of avoidable impacts across the globe in several key sectors including river and coastal flooding, cooling and heating energy demand, crop productivity and aspects of biodiversity. The avoided impacts between a scenario compatible with a 4ºC global warming and one with a 2ºC global warming were found to be highly sector dependent and avoided fractions typically ranged between 20% and 70%. A further key aspect was characterising the magnitude of the uncertainty involved, which is found to be very large in some impact sectors although the avoided fraction appears a more robust metric. The AVOID2 programme began in 2014 and will provide results in the run up to the Paris CoP in 2015. This includes new post-IPCC 5th assessment evidence to inform the long-term climate goal, a more comprehensive assessment of the uncertainty ranges of feasible emission pathways compatible with the long-term goal and enhanced estimates of global impacts using the latest generation of impact models and scenarios.

    2014-06-01

    Can mouth movements shape attitudes? When people articulate different consonants (e.g., B or K) they press the tongue and the lips against various spots in the mouth. This allows for construction of words that feature systematic wanderings of consonantal stricture spots either from the front to the rear (inward; e.g., BENOKA) or from the rear to the front (outward; e.g., KENOBA) of the mouth. These wanderings of muscular strictures resemble the oral kinematics during either deglution (swallowing-like, inward movement) or expectoration (spitting-like, outward movement). Thus, we predicted that the articulation of inward and outward words induces motivational states associated with deglutition and expectoration--namely, approach and avoidance--which was tested in 9 experiments (total N = 822). Inward words were preferred over outward words, being labeled as nonsense words (Experiments 1, 4, 5, 6, and 9), company names (Experiment 2), or person names (Experiments 3, 7, and 8), with control words falling in between (Experiment 5). As a social-behavioral consequence, ostensible chat partners were more often chosen to interact with when having inward compared to outward names (Experiment 7). The effect was found in German-speaking (Experiments 1-5) and English-speaking (Experiment 6) samples, and it occurred even under silent reading (all experiments) and for negatively labeled targets (names of villains; Experiment 8). Showing articulation simulations as being the causal undercurrent, this effect was absent in aphasia patients who lacked covert subvocalizations (Experiment 9). PMID:24841094

If these external interventions are perceived to be controlling, they are expected to crowd out intrinsic motivation, and this may also apply to...... motivation. Using a dataset with 3,230 school teachers in Denmark, a structural equation model shows that the perception of obligatory student plans as controlling is negatively associated with all of the investigated types of employee motivation, supporting that motivation crowding can occur....... other types of autonomous motivation such as public service motivation. The perception of external interventions is thus expected to be vital.

With rational coefficients, this finite filtration satisfies several of the properties of the still conjectural Bloch-Beilinson-Murre filtration.

    Disorders of diminished motivation occur frequently in individuals with traumatic brain injury. Motivation is an ever-present, essential determinant of behavior and adaptation. The major syndromes of diminished motivation are apathy, abulia, and akinetic mutism. Depending on their etiology, disorders of diminished motivation may be a primary clinical disturbance, a symptom of another disorder, or a coexisting second disorder. This article presents a biopsychosocial approach to the assessment and management of motivational impairments in patients with traumatic brain injury. The recognition and differential diagnosis of disorders of diminished motivation, as well as the mechanism and clinical pathogenesis, are discussed. PMID:16030444

    Anger has a special status among the emotions in that it can elicit avoidance as well as approach motivation. This study tested the ignored role of reward context in potentiating approach rather than avoidance responses toward objects associated with anger. In Experiment 1, angry and neutral facial expressions were parafoveally paired with common objects, and responses to the objects were assessed by subjective reports of motivation to obtain them. In Experiment 2, objects were again paired with angry or neutral faces outside of participants' awareness, and responses toward the objects were indexed by physical effort expended in attempting to win them. Results showed that approach motivation toward anger-related objects can be observed when responding is framed in terms of rewards that one can obtain, whereas avoidance motivation occurs in the absence of such a reward context. These findings point to the importance of a reward context in modulating people's responses to anger. PMID:20855898

    Spinal cord injury (SCI) pain in humans is difficult to treat, and the lack of valid methods to measure behavior comparable to the complex human pain experience preclinically represents an important obstacle to finding better treatments for this type of central pain. The place escape/avoidance paradigm (PEAP) relies on the active choice of an animal between its natural preference for a dark environment or pain relief, and it has been suggested to measure the affective-motivational component of pain. We have modified the method to a T10 spinal cord contusion model (SCC) of at-level central neuropathic pain in Sprague-Dawley rats. In order to demonstrate sensitivity to change in escape/avoidance behavior and thus the applicability of the PEAP method to predict drug efficacy, we investigated the effect of pregabalin (30 mg/kg) treatment in a randomized design. SCC animals displayed increased escape/avoidance behavior postinjury, indicating at-level mechanical hypersensitivity. Second, we found no correlation between state anxiety levels in SCC animals (elevated plus maze) and PEAP behavior, suggesting that the PEAP measurement is not biased by differences in anxiety levels. Third, we demonstrated a decrease in escape/avoidance behavior in response to treatment with the analgesic drug pregabalin. Thus, the PEAP may be applicable as a surrogate correlate of human pain. In conclusion, the primary finding in this study was a sensitivity to change in escape/avoidance behavior induced by pharmacological modulation with analgesics, supporting the use of the PEAP as a central outcome measure in preclinical SCI pain research.

    2014-03-01

    Full Text Available Objectives: 1 To identify whether patients with panic disorder in general and those with the respiratory subtype in particular actively avoid exercise; 2 to investigate physiological differences in cardiopulmonary function parameters in patients with panic disorder in general, patients with the respiratory subtype of panic disorder, and healthy controls upon exercise challenge. Methods: Patients with panic disorder were classified as having either the respiratory or the non-respiratory subtype. Both groups were compared to controls in terms of exercise avoidance patterns and performance on cardiopulmonary exercise testing. Results: Patients with panic disorder exhibited higher exercise avoidance scores and worse performance on cardiopulmonary exercise testing as compared with controls. No differences were found between patients with the respiratory and non-respiratory subtypes. Conclusions: Exercise avoidance is present in panic disorder and is associated with poorer performance on cardiopulmonary exercise testing. These findings are not limited to patients with the respiratory subtype of the disorder.

    2013-06-01

    We introduce a self-avoiding walk model for which end-effects are completely eliminated. We enumerate the number of these walks for various lattices in dimensions two and three, and use these enumerations to study the properties of this model. We find that endless self-avoiding walks have the same connective constant as self-avoiding walks, and the same Flory exponent ν. However, there is no power law correction to the exponential number growth for this new model, i.e. the critical exponent γ = 1 exactly in any dimension. In addition, the number growth has no analytic corrections to scaling, and we have convincing numerical evidence to support the conjecture that the amplitude for the number growth is a universal quantity. The technique by which end-effects are eliminated may be generalized to other models of polymers such as interacting self-avoiding walks.

    Quantum walks exhibit many unique characteristics compared to classical random walks. In the classical setting, self-avoiding random walks have been studied as a variation on the usual classical random walk. Classical self-avoiding random walks have found numerous applications, most notably in the modeling of protein folding. We consider the analogous problem in the quantum setting. We complement a quantum walk with a memory register that records where the walker has previously resided. The w...

    2016-01-01

    State fish and wildlife agencies are particularly interested in attracting female participation because of the potential to offset declining participation in hunting. Understanding female hunters’ motivations will be critical for designing effective recruitment and retention programs for women hunters. Although female participation in hunting is increasing, males still outnumber females by about tenfold. Gender differences in deer hunters were explored by comparing ratings of eight motivations (social, nature, excitement, meat, challenge, trophy, extra hunting opportunity, and solitude). Hunter types were defined by hunters’ selection of the most important motivation for why they like Black Hills deer hunting. Overall, females and males were relatively similar in their ratings of the eight motivations, and we found 85% gender similarity in the selection of the most important motivation. Women were slightly more motivated by the food aspect of the hunt while men placed slightly more value on the hunt as a sporting activity.

    Martin Plath

    2013-02-01

    Full Text Available Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P. sulphuraria that either live in hydrogen sulfide-rich (sulfidic springs or cave habitats, both of which are known to have impoverished piscine predator regimes. Focal fishes that inhabited sulfidic springs showed slightly weaker avoidance reactions when presented with several naturally occurring predatory cichlids, but strongest differences to populations from non-sulfidic habitats were found in a decreased shoaling tendency with non-predatory swordtail (Xiphophorus hellerii females. When comparing avoidance reactions between P. mexicana from a sulfidic cave (Cueva del Azufre and the adjacent sulfidic surface creek (El Azufre, we found only slight differences in predator avoidance, but surface fish reacted much more strongly to the non-predatory cichlid Vieja bifasciata. Our third experiment was designed to disentangle learned from innate effects of predator recognition. We compared laboratory-reared (i.e., predator-naïve and wild-caught (i.e., predator-experienced individuals of P. mexicana from a non-sulfidic river and found no differences in their reaction towards the presented predators. Overall, our results indicate (1 that predator avoidance is still functional in extremophile Poecilia spp. and (2 that predator recognition and avoidance reactions have a strong genetic basis.

  3. Hierarchical brain networks active in approach and avoidance goal pursuit

    2013-06-01

    Full Text Available Effective approach/avoidance goal pursuit is critical for attaining long-term health and well-being. Research on the neural correlates of key goal pursuit processes (e.g., motivation has long been of interest, with lateralization in prefrontal cortex being a particularly fruitful target of investigation. However, this literature has often been limited by a lack of spatial specificity and has not delineated the precise aspects of approach/avoidance motivation involved. Additionally, the relationships among brain regions (i.e., network connectivity vital to goal pursuit remain largely unexplored. Specificity in location, process, and network relationship is vital for moving beyond gross characterizations of function and identifying the precise cortical mechanisms involved in motivation. The present paper integrates research using more spatially specific methodologies (e.g., functional magnetic resonance imaging with the rich psychological literature on approach/avoidance to propose an integrative network model that takes advantage of the strengths of each of these literatures.

  4. Prefrontal /accumbal catecholamine system processes high motivational salience.

    Stefano Puglisi-Allegra

    2012-06-01

    Neural mechanisms mediating motivational salience attribution are, therefore, very important for individual and species survival and for well-being. However, these neural mechanisms could be implicated in attribution of abnormal motivational salience to different stimuli leading to maladaptive compulsive seeking or avoidance. We have offered the first evidence that prefrontal cortical norepinephrine transmission is a necessary condition for motivational salience attribution to highly salient stimuli, through modulation of dopamine in the nucleus accumbens, a brain area involved in all motivated behaviors. Moreover, we have shown that prefrontal-accumbal catecholamine system determines approach or avoidance responses to both reward- and aversion-related stimuli only when the salience of the unconditioned stimulus is high enough to induce sustained catecholamine activation, thus affirming that this system processes motivational salience attribution selectively to highly salient events.

    Cardiovascular disease (CVD) is the leading cause of death across all races and ethnicities. In particular, Latino men suffer disproportionately from conditions that lead to CVD such as hypertension, high cholesterol, and diabetes. There are easy and inexpensive ways to screen for certain cardiovascular conditions, yet Latino men are not benefiting from these. It is important to identify motivators and barriers to screening among this population. The purpose of this qualitative, descriptive study was to determine what motivates Latino men to participate in health screening for diabetes, high blood pressure, and high cholesterol. Self-identified Latino men (n = 17) were interviewed following a community health screening targeting Latinos. Individual semi-structured interviews were conducted in either Spanish or English after giving written consent. Trained interpreters were used for Spanish interviews. Emerging themes include motivating factors and barriers to participate in screening. Data findings direct future studies and provide culturally meaningful and relevant strategies to reduce health disparities. PMID:25823419

    Pattern avoidance in the symmetric group $S_n$ has provided a number of useful connections between seemingly unrelated problems from stack-sorting to Schubert varieties. Recent work has generalized these results to $S_n\\wr C_c$, the objects of which can be viewed as "colored permutations". Another body of research that has grown from the study of pattern avoidance in permutations is pattern avoidance in $\\Pi_n$, the set of set partitions of $[n]$. Pattern avoidance in set partitions is a generalization of the well-studied notion of noncrossing partitions. Motivated by recent results in pattern avoidance in $S_n \\wr C_c$ we provide a catalog of initial results for pattern avoidance in colored partitions, $\\Pi_n \\wr C_c$. We note that colored set partitions are not a completely new concept. \\emph{Signed} (2-colored) set partitions appear in the work of Bj\\"{o}rner and Wachs involving the homology of partition lattices. However, we seek to study these objects in a new enumerative context.

    Full Text Available Public Service Motivation concept was developed in North America and focuses on specific motivations of public servants, such as employee satisfaction, organizational commitment, reward preferences, organizational and individual performance. Other types of motivation, as financial consideration, are relevant but have less important influences with regard to this kind of work outcomes. This strengthen the assertion for a diversified motivational strategy, which affect various types of motivation, while not losing sight of the public value that one organization shows and therefore valuing public service motivation as a specific contribution to work outcomes. The concept has been increasingly applied in European public administration. This paper presents Status Quo of international Public Service Motivation research and locates in them empirical evidences from contries that are already working with this concept, like Austria. It also analyses implications for central questions of public management. The main focus of this article is general appropriateness and possible applications for Romanian public management research.

    2016-08-01

    With three studies, we investigated whether motivational states can modulate the formation of implicit preferences. In Study 1, participants played a video game in which they repeatedly approached one of two similar beverages, while disregarding the other. A subsequent implicit preference for the target beverage emerged, which increased with participants' thirst. In Study 2, participants approached one brand of potato chips while avoiding the other: Conceptually replicating the moderation observed in Study 1, the implicit preference for the approached brand increased with the number of hours from last food intake. In Study 3, we experimentally manipulated hunger, and the moderation effect emerged again, with hungry participants displaying a higher implicit preference for the approached brand, as compared to satiated participants. In the three studies, the moderation effect was not paralleled in explicit preferences although the latter were affected by the preference inducing manipulation. Theoretical implications and open questions are discussed. PMID:25948057

    2000-02-01

    In this article, we introduce the Multi-Motive Grid (MMG), a new diagnostic tool to measure motives with respect to their hope and fear components. The MMG combines features of the Thematic Apperception Test (TAT) with features of self-report questionnaires. Similar to the TAT, a set of 14 pictures representing a balanced set of achievement-arousing, affiliation-arousing, and power-arousing situations is presented together with a set of statements representing important motivational states. Six motive scores can be calculated: hope of success (HS) and fear of failure (FF) for the achievement motive, hope of affiliation (HA) and fear of rejection (FR) for the affiliation motive, and hope of power (HP) and fear of power (FP) for the power motive. Results of factor analyses suggest a 3-factor solution, with a general fear factor (FF, FR, FP), a factor combining the hope components of achievement and power (HS and HP), and a third factor representing HA, but the 6 a priori factors also reflect a sound structural model. Reliability data show that the internal consistency and retest reliability of the MMG scales satisfy traditional standards. External validity of the MMG has been established in all 3 motive domains. Three separate studies document that (a) individuals high in resultant achievement motivation perform better and report more flow experience, (b) individuals high in resultant power motivation profit more from a leadership training program, and (c) individuals high in resultant affiliation motivation recollect more highly memorable affiliative themes.

    This article follows up on a study by Dagut and Laufer (1985), who found that Hebrew learners of English avoid phrasal verbs, such as ‘let down’, while preferring one-word verbs, such as ‘;disappoint’, since phrasal verbs do not exist in Hebrew. A corollary derived from Dagut and Laufer's study is that Dutch learners of English would tend not to avoid English phrasal verbs, since phrasal verbs also exist in Dutch.

    Full Text Available Research Question (RQ: How to motivate employees and keep them motivated? Purpose: The purpose of this study is to find out what motivates employees and what motivates employees for work. Method: The results of the questionnaire are graphically presented and described. Random sampling was utilized that included participants from various professional areas and demographic characteristics. The results showed a relationship between individual motivational factors related to education, age and type of employment. All of the questions were closed - type questions except for the last question, which was an open question, in which the respondents answered in their own words. Questions were analyzed using frequency analysis of individual responses. Pearson's Chi - squared test, Spearman's rank correlation and Fisher’s Exact test was made using R Commander. Results: The research findings showed which motivational factors motivate employees the most. These are especially non - material motivational factors, such as good relationships, jobs with challenges, advancement opportunities, clear instructions, good work conditions, company reputation, etc. Organization: The study will help managers understand their role in motivating employees as well as the types of motivational factors. Society: The research shows how individuals are motivated. Originality: Certain motivators in the study are ranked differently than was found in previous literature. Most probably the reason is that the respondents in this study favored intangible motivators (good relations with leadership and their colleagues, good working conditions, etc.. Limitations/Future Research: The limitation of this study was that the sample included employees of different ages, gender and years of service in various organizations. To enhance the study and to find similar results as in previous literature, more questions should have been asked as well as increasing the sample size.

    Full Text Available The aim of the article. The aim of the article is to develop scientific and methodic grounds to form motivational constituent of the international ecological policy. The results of the analysis. Directions to improve activity and efficiency of the international ecological policy consist in improvement or change of the existing elements in natural management mechanism, forms and tools of ecopolicy. Therefore motivating mechanism of environmental protection and rational natural management has prior value. One of the main points to form motivating tools system has to be increasing of the economic activity total efficiency in the country. Its achievement depends on ratio between change in efficiency of the ecodestructive and ecologically oriented innovative activity. Authors present graphically and ground possible variants of innovative activity efficiency while using economic motivating tools of its ecologization. Authors also suggest to use curve, which describes inequality of ecodestructive impact distinguish, to determine perspectives for innovative activity ecologization motivating creation in the country. The proposed methodic approach is used only to analyze enterprises ecological compatibility, which has destructive impact on environment. Inequality coefficient is suggested to measure degree of ecodestructive impact distinguish inequality degree. Authors investigated principle scheme to define potential of innovative activity ecologization motivating depending on the received inequality coefficient of the ecodestructive impact distinguish and type of the distinguish curve. In order to avoid subjectivity of ecodestructive impact distinguish curve one suggests to use formalized procedure, which foresees determination of distinguish curve type by results of shifting coefficient calculation. In order to form efficient system of the innovative activity ecologization motivating one proposes to use developed map of the relative socio

    Full Text Available The purpose of this work is to identify whether there are combinations of multiple goals that lead to different motivational profiles. The sample is made up of 1924 university students. By means of cluster analysis, six motivational profiles were identified. The results indicate that the motivationalprofile that comprises students who are motivated to learn, but also to achieve better results that the rest and to avoid making a bad impression on them are the students who report better academic achievement and also the students who believe they have a higher level of knowledge in the academic subjects they are studying. However, students with a learning oriented motivational profile value the tasks more, have more control over their learning process, and have lower levels of anxiety.

  13. Avoiding unfavourable outcomes in liposuction

    2013-01-01

    Full Text Available The origin of liposuction can be traced to an adverse event by Dujarrier in 1921 when he used a uterine curette to remove fat from the knees of a ballerina ending in an amputation secondary to damage of the femoral artery. The history of liposuction since then has been one of avoiding complications and optimising outcome. After this adverse event, liposuction was abandoned until the 1960′s when Schrudde revived the practice using small stab incisions and sharp curettage with the secondary suction to aspirate the freed tissue. This technique was associated with a high incidence of complications especially seroma and skin necrosis. Illouz then replaced the curette with a blunt cannula connected to vacuum pump thus avoiding the complications of a sharp curette. Despite the presence of various techniques for liposuction, suction assisted liposuction (SAL is still the standard technique of liposuction. This article aims to discuss literature regarding the various aspects of liposuction (SAL and to highlight the salient points in the literature and in the senior author′s experience in order to avoid unfavourable outcomes in liposuction. A literature review on avoiding complication is in liposuction including some of the seminal papers on liposuction. Liposuction is generally a safe procedure with reproducible outcome. Just like any surgical procedure it should be treated with the utmost care. Illouz published 10 commandments for liposuction in 1989 and we review these commandments to demonstrate how liposuction has evolved.

    2011-01-01

    [Objective] The aim was to explore the achievement motivation of the university student village officials in the suburbs of Beijing.[Method] The research made an investigation on 429 university student village officials in the suburbs of Beijing by the Achievements Motive Scale (AMS). [ Result] The achievement motivation of these student village officials was not on a high level, but they tended to pursue the success motivation rather than the motivation to avoid failures obviously. There was a significant difference in the achievement motivation between different genders, majors and jobs. The males' motivation for success was higher than the females'. The motivation of avoiding failures among officials in Humanities was higher than in Science and in Fine Art. And the university student village officials in professional and technical posts or in business posts rated the motivation to avoid failures more important than in basic management posts. But achievement motivations in different urban-rural areas, educational levels, political backgrounds, whether student leaders or not, and durations were no definite differences. Besides, it had a significant effect on these student village officials' achievement motivation whether advices and suggestions were accepted; if yes,the motivation was higher. [ Conclusion] This study had provided stability and development for building rural talent groups.

  15. How to avoid unnatural hierarchical thermal leptogenesis

    CERN Document Server

    Clarke, Jackson D

    2015-01-01

    A one-flavour naturalness argument suggests that the Type I seesaw model cannot naturally explain neutrino masses and the baryon asymmetry of the Universe via hierarchical thermal leptogenesis. We prove that there is no way to avoid this conclusion in a minimal three-flavour setup. We then comment on the simplest ways out. In particular, we focus on a resolution utilising a second Higgs doublet. Such models predict an automatically SM-like Higgs boson, (maximally) TeV-scale scalar states, and low- to intermediate-scale hierarchical leptogenesis with $10^3\\text{ GeV}\\lesssim M_{N_1}\\lesssim 10^7\\text{ GeV}$.

    Full Text Available The objective of this paper is to propose a robust obstacle avoidance method for service robot in indoor environment. The method for obstacles avoidance uses information about static obstacles on the landmark using edge detection. Speed and direction of people that walks as moving obstacle obtained by single camera using tracking and recognition system and distance measurement using 3 ultrasonic sensors. A new geometrical model and maneuvering method for moving obstacle avoidance introduced and combined with Bayesian approach for state estimation. The obstacle avoidance problem is formulated using decision theory, prior and posterior distribution and loss function to determine an optimal response based on inaccurate sensor data. Algorithms for moving obstacles avoidance method proposed and experiment results implemented to service robot also presented. Various experiments show that our proposed method very fast, robust and successfully implemented to service robot called Srikandi II that equipped with 4 DOF arm robot developed in our laboratory.

    Full Text Available Different motivational theories in the literature seem to claim unique explanations of motivational behaviour. When these theories are evaluated against basic concepts and the process of motivation, it becomes clear that theory building in motivational terms really focuses on the same basic phenomenon. The implications and practical applications of the more job related contemporary theories of motivation are discussed. OpsommingDie indruk wat verskillende motiveringsteorieë in die literatuur skep, is dat elke teorie 'n unieke verklaring gee van gemotiveerde gedrag. Indien die basisbegrippe en die motiveringsproses egter as ankers gebruik word om teorieë te ontleed is dit moontlik om aan te toon dat teoriebou in die motiveringsliteratuur, niks anders is as beligtingsaspekte van dieselfde fenomeen nie.

    The radiologic career field has undergone radical changes in technology, regulatory compliance, and customer expectation.These changes often require dramatic alterations to processes,which can break down communication, create stress, and have a negative effect on department productivity. Motivation itself is a frequently analyzed and reported topic in professional publications. For this purpose, this literature review specifically researches motivation as identified by radiology administrators through Radiology Management. Three key elements surfaced as those with the most impact: (1) motivation is an intrinsic factor which can be influenced but not created, (2) clear attainable goals are an essential component of motivation,and (3) motivation begins with identification of employee needs.

    Although close relationships require partners to depend on one another for mutual responsiveness, avoidantly-attached individuals are especially averse to risking such dependency. The authors propose that both avoidant and non-avoidant individuals perceive signs of their own and their partners’ responsiveness in ways that reflect motivated perceptions of dependency. The present research examined how the interplay between spouses’ attachment avoidance and observed responsive behaviors during marital conflict shaped perceptions of their own and their partners’ responsiveness. Newlywed couples attempted to resolve a relationship conflict, then reported perceptions of their own and their partners’ responsiveness during the conflict. Observers also coded both partners’ responsive behaviors during the conflict. Avoidant husbands perceived themselves as less responsive than did observers; avoidant wives’ perceptions that their husbands were less responsive matched observers’ ratings. The discussion highlights the role of gender role norms in understanding links between attachment and responsiveness. PMID:24132245

  17. Optimal deadlock avoidance Petri net supervisors for automated manufacturing systems

    2007-01-01

    Deadlock avoidance problems are investigated for automated manufacturing systems with flexible routings.Based on the Petri net models of the systems, this paper proposes, for the first time, the concept of perfect maximal resourcetransition circuits and their saturated states. The concept facilitates the development of system liveness characterization and deadlock avoidance Petri net supervisors. Deadlock is characterized as some perfect maximal resource-transition circuits reaching their saturated states. For a large class of manufacturing systems, which do not contain center resources, the optimal deadlock avoidance Petri net supervisors are presented. For a general manufacturing system, a method is proposed for reducing the system Petri net model so that the reduced model does not contain center resources and, hence, has optimal deadlock avoidance Petri net supervisor. The controlled reduced Petri net model can then be used as the liveness supervisor of the system.

    2013-01-01

    We prove error bounds in a central limit theorem for solutions of certain convolution equations. The main motivation for investigating these equations stems from applications to lace expansions, in particular to weakly self-avoiding random walks in high dimensions. As an application we treat such self-avoiding walks in continuous space. The bounds obtained are sharper than the ones obtained by other methods.

    Approach and avoidance are two basic motivational orientations. Their activation influences cognitive and perceptive processes: Previous work suggests that an approach orientation instigates a focus on larger units as compared to avoidance. Study 1 confirms this assumption using a paradigm that more directly taps a person’s tendency to represent objects as belonging to small or large units than prior studies. It was further predicted that the self should also be represented as belonging to la...

    Full Text Available Two diary studies investigated the role of social approach and avoidance motivation in important developmental transitions in young and old adulthood. Study 1 comprised a sample of young adults (N = 93, M = 21.5 years who moved out of their parental homes. The sample of Study 2 consisted of older adults (N = 69, M = 76.95 years who moved into senior housing. In both studies, participants reported their habitual social approach and avoidance motives as well as their daily social experience and subjective well-being over the course of two weeks. In line with the literature, social approach motives and age were related to higher subjective well-being, whereas social avoidance motives were negatively associated with subjective well-being. Time since the transition was an important moderator of the association between social avoidance motives and negative outcomes. With increasing time from the transition, the negative effects of social avoidance motives decreased. The positive effects of social approach motives remained fairly stable over time. Importantly, age did not moderate any of the associations between social motivation and outcomes. Results are discussed in terms of transition-related instability and age-related stability.

    2016-01-01

    Many car-following models are developed for jam avoidance in highways. Two mechanisms are used to improve the stability: feedback control with autonomous models and increasing of the interaction within cooperative ones. In this paper, we compare the linear autonomous and collective optimal velocity (OV) models. We observe that the stability is significantly increased by adding predecessors in interaction with collective models. Yet autonomous and collective approaches are close when the speed difference term is taking into account. Within the linear OV models tested, the autonomous models including speed difference are sufficient to maximise the stability.

  5. How to help the patient motivate himself?

    Science.gov (United States)

    2012-03-01

    In order to help a patient with a chronic disease motivate himself, caregivers spontaneously make use of reason with a view to having the patient share the caregivers' point of view, in other words, to some extent, transforming the care recipient into a caregiver. However, it is not unusual for a caregiver suffering from the disease in which he specializes not to treat himself in compliance with the rules he recommends to his patients. Man is a trinity with three instances of the self. In addition to the "rational self" that tends towards the universal, there is also an "animal self" subject to powerful, frequently imperious, primary needs which may be compared to impulsions, compulsions and addictions. Lastly, there is an "identity self", an irreducible singularity, governed by the law of optimizing pleasure or, in any event, avoiding moral distress. The patient has to learn to navigate between objectives oriented by reason, more or less imperious urges and the striving for well-being and avoidance of moral distress. These various instances of the "self" have a distinct relationship with the norm and with time. Psychologists recognize two types of motivation: intrinsic motivation, an activity implemented for itself, and extrinsic motivation, an activity practiced for its secondary beneficial effects. Clearly, caring for oneself derives from an extrinsic motivation. This motivation may be very powerful but is frequently of limited duration. Helping a patient suffering from a chronic disease motivate himself over time thus consists in helping the patient take on board an extrinsic motivation in order for the treatment to become a routine or a source of satisfaction or even pleasure. The physician has to promote the acquisition of self-care skills and a feeling of success in the patient. The physician is also to help the patient negotiate the optimum compromise between his "rational self" and his "identity self" by acting as the advocate of the two parties, while not

    1991-01-01

    A system for guiding an autonomous or semi-autonomous vehicle through a field of operation having obstacles thereon to be avoided employs a memory for containing data which defines an array of grid cells which correspond to respective subfields in the field of operation of the vehicle. Each grid cell in the memory contains a value which is indicative of the likelihood, or probability, that an obstacle is present in the respectively associated subfield. The values in the grid cells are incremented individually in response to each scan of the subfields, and precomputation and use of a look-up table avoids complex trigonometric functions. A further array of grid cells is fixed with respect to the vehicle form a conceptual active window which overlies the incremented grid cells. Thus, when the cells in the active window overly grid cell having values which are indicative of the presence of obstacles, the value therein is used as a multiplier of the precomputed vectorial values. The resulting plurality of vectorial values are summed vectorially in one embodiment of the invention to produce a virtual composite repulsive vector which is then summed vectorially with a target-directed vector for producing a resultant vector for guiding the vehicle. In an alternative embodiment, a plurality of vectors surrounding the vehicle are computed, each having a value corresponding to obstacle density. In such an embodiment, target location information is used to select between alternative directions of travel having low associated obstacle densities.

  10. Adaptive avoidance of reef noise.

    Directory of Open Access Journals (Sweden)

    Stephen D Simpson

    Full Text Available Auditory information is widely used throughout the animal kingdom in both terrestrial and aquatic environments. Some marine species are dependent on reefs for adult survival and reproduction, and are known to use reef noise to guide orientation towards suitable habitat. Many others that forage in food-rich inshore waters would, however, benefit from avoiding the high density of predators resident on reefs, but nothing is known about whether acoustic cues are used in this context. By analysing a sample of nearly 700,000 crustaceans, caught during experimental playbacks in light traps in the Great Barrier Reef lagoon, we demonstrate an auditory capability in a broad suite of previously neglected taxa, and provide the first evidence in any marine organisms that reef noise can act as a deterrent. In contrast to the larvae of species that require reef habitat for future success, which showed an attraction to broadcasted reef noise, taxa with a pelagic or nocturnally emergent lifestyle actively avoided it. Our results suggest that a far greater range of invertebrate taxa than previously thought can respond to acoustic cues, emphasising yet further the potential negative impact of globally increasing levels of underwater anthropogenic noise.

    According to a review of the current literature, common managerial styles are transformational, transactional, and laissez-faire. When managers expand their leadership skills to improve the staff's morale, they must use a combination of transformational leadership behaviors and transactional contingent rewards to maximize their effectiveness on employees. A motivation theory such as Herzberg and Maslow enhances employees' motivation, morale, and satisfaction. Being able to motivate, empower, and influence staff improves satisfaction and retention levels among the team. A manager's leadership style influences motivation, morale, and retention in staff. Leaders are influenced by their educational development and the organizational culture. Organizational culture has an impact on a manager's style, which is forwarded to their followers.

    To monitor science motivation, 232 tenth graders of the college preparatory level ('Gymnasium') completed the Science Motivation Questionnaire II (SMQ-II). Additionally, personality data were collected using a 10-item version of the Big Five Inventory. A subsequent exploratory factor analysis based on the eigenvalue-greater-than-one criterion, extracted a loading pattern, which in principle, followed the SMQ-II frame. Two items were dropped due to inappropriate loadings. The remaining SMQ-II seems to provide a consistent scale matching the findings in literature. Nevertheless, also possible shortcomings of the scale are discussed. Data showed a higher perceived self-determination in girls which seems compensated by their lower self-efficacy beliefs leading to equality of females and males in overall science motivation scores. Additionally, the Big Five personality traits and science motivation components show little relationship.

  4. Threat of punishment motivates memory encoding via amygdala, not midbrain, interactions with the medial temporal lobe.

    Murty, Vishnu P; Labar, Kevin S; Adcock, R Alison

    2012-06-27

    Neural circuits associated with motivated declarative encoding and active threat avoidance have both been described, but the relative contribution of these systems to punishment-motivated encoding remains unknown. The current study used functional magnetic resonance imaging in humans to examine mechanisms of declarative memory enhancement when subjects were motivated to avoid punishments that were contingent on forgetting. A motivational cue on each trial informed participants whether they would be punished or not for forgetting an upcoming scene image. Items associated with the threat of shock were better recognized 24 h later. Punishment-motivated enhancements in subsequent memory were associated with anticipatory activation of right amygdala and increases in its functional connectivity with parahippocampal and orbitofrontal cortices. On a trial-by-trial basis, right amygdala activation during the motivational cue predicted hippocampal activation during encoding of the subsequent scene; across participants, the strength of this interaction predicted memory advantages due to motivation. Of note, punishment-motivated learning was not associated with activation of dopaminergic midbrain, as would be predicted by valence-independent models of motivation to learn. These data are consistent with the view that motivation by punishment activates the amygdala, which in turn prepares the medial temporal lobe for memory formation. The findings further suggest a brain system for declarative learning motivated by punishment that is distinct from that for learning motivated by reward. PMID:22745496

    Full Text Available Elevated levels of fear and avoidance are core symptoms across the anxiety disorders. It has long been known that fear serves to motivate avoidance. Consequently, fear extinction has been the primary focus in pre-clinical anxiety research for decades, under the implicit assumption that removing the motivator of avoidance (fear would automatically mitigate the avoidance behaviors as well. Although this assumption has intuitive appeal, it has received little scientific scrutiny. The scarce evidence from animal studies is mixed, while the assumption remains untested in humans. The current study applied an avoidance conditioning protocol in humans to investigate the effects of fear extinction on the persistence of low-cost avoidance. Online danger-safety ratings and skin conductance responses documented the dynamics of conditioned fear across avoidance and extinction phases. Anxiety- and avoidance-related questionnaires explored individual differences in rates of avoidance. Participants first learned to click a button during a predictive danger signal, in order to cancel an upcoming aversive electrical shock (avoidance conditioning. Next, fear extinction was induced by presenting the signal in the absence of shocks while button-clicks were prevented (by removing the button in Experiment 1, or by instructing not to click the button in Experiment 2. Most importantly, post-extinction availaibility of the button caused a significant return of avoidant button-clicks. In addition, trait-anxiety levels correlated positively with rates of avoidance during a predictive safety signal, and with the rate of pre- to post-extinction decrease during this signal. Fear measures gradually decreased during avoidance conditioning, as participants learned that button-clicks effectively canceled the shock. Preventing button-clicks elicited a sharp increase in fear, which subsequently extinguished. Fear remained low during avoidance testing, but danger-safety ratings

    Many psychological phenomena have been explained primarily in terms of intrapsychic motives to maintain particular cognitive or affective states--such as motives for consistency, self-esteem, and authenticity--whereas other phenomena have been explained in terms of interpersonal motives to obtain tangible resources, reactions, or outcomes from other people. In this article, we describe and contrast intrapsychic and interpersonal motives, and we review evidence showing that these two distinct sets of motives are sometimes conflated and confused in ways that undermine the viability of motivational theories. Explanations that invoke motives to maintain certain intrapsychic states offer a dramatically different view of the psychological foundations of human behavior than those that posit motives to obtain desired interpersonal outcomes. Several phenomena are examined as exemplars of instances in which interpersonal and intrapsychic motives have been inadequately distinguished, if not directly confounded, including cognitive dissonance, the self-esteem motive, biases in judgment and decision making, posttransgression accounts, authenticity, and self-conscious emotions. Our analysis of the literature suggests that theorists and researchers should consider the relative importance of intrapsychic versus interpersonal motives in the phenomena they study and that they should make a concerted effort to deconfound intrapsychic and interpersonal influences in their research.

    Full Text Available The possibility of the presence of inter-individual emotional differences and the memory performance of rats was examined in the elevated T-maze. Two kinds of aversively motivated behaviors, inhibitory avoidance and escape learning, were measured. Based on the number of trials to achieve a learning criterion, rats were divided into two subgroups with either low or high avoidance reactivity (LAR or HAR, respectively. Retention test avoidance latencies showed that HAR animals had better avoidance memory (Mann-Whitney rank sum test, P = 0.0035. No such differences were found for the escape component of this test. These data suggest that individual emotional differences affect inhibitory avoidance performance, which may help to explain the dispersion of the data observed in other studies using this paradigm.

    The d and f electrons in correlated metals are often neither fully localized around their host nuclei nor fully itinerant. This localized/itinerant duality underlies the correlated electronic states of the high-Tc cuprate superconductors and the heavy-fermion intermetallics and is nowhere more apparent than in the 5f valence electrons of plutonium. Here, we report the full set of symmetry-resolved elastic moduli of PuCoGa5--the highest Tc superconductor of the heavy fermions (Tc = 18.5 K)--and find that the bulk modulus softens anomalously over a wide range in temperature above Tc. The elastic symmetry channel in which this softening occurs is characteristic of a valence instability--therefore, we identify the elastic softening with fluctuations of the plutonium 5f mixed-valence state. These valence fluctuations disappear when the superconducting gap opens at Tc, suggesting that electrons near the Fermi surface play an essential role in the mixed-valence physics of this system and that PuCoGa5 avoids a valence transition by entering the superconducting state. The lack of magnetism in PuCoGa5 has made it difficult to reconcile with most other heavy-fermion superconductors, where superconductivity is generally believed to be mediated by magnetic fluctuations. Our observations suggest that valence fluctuations play a critical role in the unusually high Tc of PuCoGa5. PMID:25737548

  16. (Mis)managing employee motivation?

    DEFF Research Database (Denmark)

    Jacobsen, Christian Bøtcher; Hvidtved, Johan; Andersen, Lotte Bøgh

    Motivated employees are crucial to all organizations, but some management initiatives may actually decrease motivation. Motivation crowding theory thus expects that command and incentives – if they are perceived as controlling - crowd out intrinsic motivation. The perception is thus expected to be...... vital, and this paper investigates how the perception of a specific command system – obligatory student plans – is associated with two types of employee motivation (public service motivation and intrinsic task motivation). Using a dataset with 3439 school teachers in Denmark, the analysis shows that the...... perception of obligatory student plans as controlling is negatively associated with different types of employee motivation, indicating that motivation crowding happens. Although the strength of the associations varies between the investigated types of motivation, the findings imply that practitioners should...

  17. Motivational drive and alprazolam misuse: A recipe for aggression?

    Benzodiazepine-related aggression has received insufficient research attention, in particular little is known about the motivational factors which may contribute to the development of this paradoxical response. The revised Reinforcement Sensitivity Theory provides a theoretical framework from which to understand the relevant underlying motivational processes. The current study aimed to identify the role of approach and avoidance motivational tendencies in the occurrence of benzodiazepine-related aggression. Data regarding benzodiazepine and other substance use, approach and avoidance motivation, and general and physical aggressive behaviour were collected via self-report questionnaires. Participants were a convenience sample (n=204) who reported using benzodiazepines in the previous year. Participants were primarily male (62.7%), aged 18-51 years old. Hierarchical multiple regressions indicated that general and physical aggression were predicted by alprazolam use and Drive, a facet of approach motivation. Overall, lower diazepam use significantly predicted higher levels of general aggression. However, when diazepam-preferring participants were examined in isolation of the larger sample (23.5% of sample), problematic (dependent) diazepam use was associated with greater aggression scores, as was dependence risk for alprazolam-preferring participants (39.7% of sample). The findings highlight the importance of motivational factors and benzodiazepine use patterns in understanding benzodiazepine-related aggression, with implications for violent offender rehabilitation.

  19. Patterns of alpha asymmetry in those with elevated worry, trait anxiety, and obsessive-compulsive symptoms: A test of the worry and avoidance models of alpha asymmetry.

    Science.gov (United States)

    2016-05-01

    Some authors have argued that worry cues lateralization of frontal brain activity leftward, whereas other varieties of avoidance motivation cue lateralization of frontal brain activity rightward. By comparison, more right-than-left parietal activity correlates with anxious arousal. The purpose of the present report was to test two models of brain lateralization and anxiety: one model that proposed that worry correlates with more left-frontal activity and another model that proposed that avoidance motivation (including worry) correlates with more right-frontal activity. Undergraduate students were selected for worry, obsessive-compulsive symptoms, and trait anxiety using self-report questionnaires. A subset of participants also met DSM-IV criteria for Generalized Anxiety Disorder (GAD) or Obsessive-Compulsive Disorder (OCD). Alpha asymmetry and also a global-power-adjusted metric of alpha power were calculated from each participant's resting-state EEG. It was expected that participants with elevated worry and participants meeting criteria for GAD would show more left-than-right frontal activity. In contrast, participants with elevated trait anxiety, obsessive-compulsive symptoms, and those with an OCD diagnosis were expected to exhibit more right-than-left frontal activity. Participants with elevated worry, participants with a GAD diagnosis, and participants with elevated obsessive-compulsive symptoms, had more left frontal activity than low symptom individuals. Those with high scores on trait anxiety, but low worry, had greater right frontal and parietal activity compared to controls. The present results suggest that brain lateralization is not solely related to avoidance motivation, and suggest that facets of anxiety may cut across dimensions not well-represented by DSM-based categories.

    In everyday life, motivation and learning are connected like music and dancing. Many educators realize this and work hard to improve their students' motivation. A motivated student may repeat and self-rehearse the content of a chapter more often, which leads to better learning.

That is, would a motivated student perform be...

  4. From Readiness to Action: How Motivation Works

    Directory of Open Access Journals (Sweden)

    Kruglanski Arie W.

    2014-09-01

    Full Text Available We present a new theoretical construct labeled motivational readiness. It is defined as the inclination, whether or not ultimately implemented, to satisfy a desire. A general model of readiness is described which builds on the work of prior theories, including animal learning models and personality approaches, and which aims to integrate a variety of research findings across different domains of motivational research. Components of this model include the Want state (that is, an individual’s currently active desire, and the Expectancy of being able to satisfy that Want. We maintain that the Want concept is the critical ingredient in motivational readiness: without it, readiness cannot exist. In contrast, some motivational readiness can exist without Expectancy. We also discuss the role of incentive in motivational readiness. Incentive is presently conceived of in terms of a Match between a Want and a Perceived Situational Affordance. Whereas in classic models incentive was portrayed as a first order determinant of motivational readiness, here we describe it as a second order factor which affects readiness by influencing Want, Expectancy, or both. The new model’s relation to its theoretical predecessors, and its implications for future research, also are discussed.

    Full Text Available Background: Motivation is an important issue for personnel management in health care settings, as it is related to both performance and intention to quit. Objectives: The study was aimed to determine nurses’ working motivation sources and related factors in hospitals. Design: Descriptive study. Settings: A state university hospital and a public hospital in Turkey. Participants: Two hundred and two nurses were randomly selected from each department in a university and in a public hospital. Methods: Data were collected using a socio-demographic questionnaire and the Motivation Sources Inventory and were analyzed using descriptive and inferential statistics. Results: Among five motivation sources, internal self-concept-based motivation was the highest and intrinsic process motivation was the lowest in nurses. There was a significant relation between scores of some motivation sources and managerial experience, income level, satisfaction from the unit, staff roles, and perception of work stress. Conclusions: Intrinsic process motivation, instrumental motivation, and external self-concept-based motivation sources may be improved to increase nurses’ total motivation.

The opportunity of direct interaction with the tourists makes them all the more responsible for projecting the correct image of the country/region, giving factually correct information about the destination, ensuring the safety and well being of the tourists as well as pleasing and satisfying the stay for them during their visits. Over last few years there has been a greater interest in tour guide profession especially in the northern region of India.The purpose of this study is to identify the motivations that led to choosing tour guiding as a profession and career. There appears to be a significant difference in such motivation in different regions of the country. A comparison in motivations in two regions (north vs. east was made. Based on primary data collection paper attempts to discuss what has motivated the youth to take up tour guiding profession- whether such motivation is positive of negative. In either case policy makers may decide what type of support programs need to be introduced by the state and other agencies like educational, rearing and counselling, financial support, social security, or any other type of interventions.

    The aim of this study was to investigate the relations among situational motivational climate, dispositional approach and avoidance achievement goals, perceived sport ability, and enjoyment in Finnish male junior ice hockey players. The sample comprised 265 junior B-level male players with a mean age of 17.03 years (SD = 0.63). Players filled questionnaires tapping their perceptions of coach motivational climate, achievement goals, perceived sport ability, and enjoyment. For the statistical analysis, players were divided into high and low perceived sport ability groups. Multigroup structural equation modeling (SEM) revealed an indirect path from task-involving motivational climate via task-approach goal to enjoyment. Additionally, SEM demonstrated four other direct associations, which existed in both perceived ability groups: from ego-involving motivational climate to ego-approach and ego-avoidance goals; from ego-approach goal to ego-avoidance goal; and from task-avoidance goal to ego-avoidance goal. Additionally, in the high perceived sport ability group, there was an association from task-involving motivational climate to enjoyment. The results of this study reveal that motivational climate emphasizing effort, personal development and improvement, and achievement goal mastering tasks are significant elements of enjoyment in junior ice hockey.

    A simple periodically driven system displaying rich behavior is introduced and studied. The system self-organizes into a mosaic of static ordered regions with three possible patterns, which are threaded by one-dimensional paths on which a small number of mobile particles travel. These trajectories are self-avoiding and non-intersecting, and their relationship to self-avoiding random walks is explored. Near ρ=0.5 the distribution of path lengths becomes power-law-like up to some cutoff length, suggesting a possible critical state.

    Full Text Available In this study, the researchers surveyed 130 language learners enrolled in first-year foreign language classrooms in a public university in Utah, United States. This study intended to address the following research questions: (1 What motivational factors are found among learners enrolled in first-year foreign language courses at the university level in the United States?, (2 Do first-year language learners' motivations differ based on the following learner variables: (a gender, (b language being learned, (c major, and (d religion? and (3 What motivational factors predict learners' interest in continuing foreign language learning? Factor analysis, MANOVA, and multiple regressions were run to answer the questions. The factor analysis results found seven motivational factors: positive learning attitudes/experience and intended efforts, interest in culture, travel, and people, interest in contemporary cultural media, milieu, instrumentality, language requirement, and religion.

  17. Generalized atmospheric sampling of self-avoiding walks

    International Nuclear Information System (INIS)

    In this paper, we introduce a new Monte Carlo method for sampling lattice self-avoiding walks. The method, which we call 'GAS' (generalized atmospheric sampling), samples walks along weighted sequences by implementing elementary moves generated by the positive, negative and neutral atmospheric statistics of the walks. A realized sequence is weighted such that the average weight of states of length n is proportional to the number of self-avoiding walks from the origin cn. In addition, the method also self-tunes to sample from uniform distributions over walks of lengths in an interval [0, nmax]. We show how to implement GAS using both generalized and endpoint atmospheres of walks and analyse our data to obtain estimates of the growth constant and entropic exponent of self-avoiding walks in the square and cubic lattices.

  19. Predictive Potential Field-Based Collision Avoidance for Multicopters

    2013-08-01

    Reliable obstacle avoidance is a key to navigating with UAVs in the close vicinity of static and dynamic obstacles. Wheel-based mobile robots are often equipped with 2D or 3D laser range finders that cover the 2D workspace sufficiently accurate and at a high rate. Micro UAV platforms operate in a 3D environment, but the restricted payload prohibits the use of fast state-of-the-art 3D sensors. Thus, perception of small obstacles is often only possible in the vicinity of the UAV and a fast collision avoidance system is necessary. We propose a reactive collision avoidance system based on artificial potential fields, that takes the special dynamics of UAVs into account by predicting the influence of obstacles on the estimated trajectory in the near future using a learned motion model. Experimental evaluation shows that the prediction leads to smoother trajectories and allows to navigate collision-free through passageways.

    Full Text Available Motivation of students is one of the most efficient means of improving process and results of training, and motives being impetus of academic process and qualitative mastering of learning material. Formation of academic motivation today is one of the main tasks of up to date education. Academic motivation depends on individual peculiarities of students, character of the closest referent group, level of development of students’ collective, etc. Aim of the research was 1 studying level of academic motivation of students of SE “Dnipropetrovsk medical academy of HM of Ukraine”; 2 revealing prevailing motives of educational activity of students of high medical establishment; 3 assessment of moral readiness of students to inevitable mistakes in future work; 4 studying dynamics of motivation sphere of future doctors in the course of the studies in high medical school; 5 comparison of motivation and intellectual indices of students of junior, pre-graduate and graduate courses; 6 recommendations for lecturers as for improvement of academic motivation of the students. By means of anonymous testing of 537 students of the first, fifth and sixth courses there were studied peculiarities of academic motivation and intellectual indices of the students. Academic motivation of students at large is sufficiently high. Professional and scientific-cognitive motives of educational activity are the most expressed ones. Communicative motives and those of creative self-realization are somewhat less, social motives and motives of prestige are much less. Rather low indices of failure avoidance testify to moral mood of students to inevitable mistakes in their future work. On the whole, a tendency to academic motivation decreasing in the course of studies was revealed. Expressiveness of academic motivation does not depend on intellectual indices of students.

  1. Exergaming, Exercise, and Gaming: Sharing Motivations.

    Osorio, Gume; Moffat, David C; Sykes, Jonathan

    2012-06-01

    Health professionals view exergame technologies as an alternative tool in therapeutic treatments and the promotion of physical activity. There is a growing body of work addressing the health benefits of exergaming; however, there is limited knowledge concerning user experience in this new context. If we aim to encourage participation in exergaming, we must first understand why gamers currently play exergames. Exergaming refers to the computer games that require players to perform some level of physical exertion to play. For this reason, the present study compares the motivations that encourage participation in three contexts (exercise, computer games, and exergaming) to identify key elements that support such participation. Survey instruments were administered in each context, and motivational components were addressed within self-determination theory. Findings suggest perceptions of enjoyment and feeling better after a session and participation within a social context are key factors that encourage participation in the three contexts. Participation in exergaming is also encouraged by perceptions of performing mild exercise while playing videogames. Exergamers might not experience an optimal challenge while playing, and this may lower their motivation. Participation in exercise is also encouraged by perceptions of being healthier and, in some instances, driven to avoid feelings of guilt. Gamers also play computer games encouraged by perceptions being in a better mood after session, although some gamers might also participate aiming to gain social acceptance. PMID:26193438

  2. A Brief History of Attempts to Measure Sexual Motives

    Directory of Open Access Journals (Sweden)

    Elaine Hatfield

    2012-12-01

    Full Text Available Artists, creative writers, and musicians have long been interested in the complex motives that spark passionate love, sexual desire, and sexual behavior. Recently, scholars from a variety of disciplines have begun to investigate two questions: “Why do men and women choose to engage in sexual liaisons?” “Why do they avoid such encounters?” Theories abound. Many theorists have complained that there exists a paucity of scales designed to measure the plethora of motives that prompt people to seek out or to avoid sexual activities. In fact, this observation is incorrect. Many such scales of documented reliability and validity do exist. The reason that few scholars are familiar with these scales is that they were developed by psychometricians from a variety of disciplines and are scattered about in an assortment of journals, college libraries, and researchers’ desk drawers, thus making them difficult to identify and locate. This paper will attempt to provide a compendium of all known sexual motives scales, hoping that this will encourage scholars to take a multidisciplinary approach in developing typologies of sexual motives and/or in conducting their own research into the nature of sexual motives.

    2006-02-01

    126 leaders and 624 employees were sampled to test the relationship between sources of motivation and conflict management styles of leaders and how these variables influence effectiveness of leadership. Five sources of motivation measured by the Motivation Sources Inventory were tested-intrinsic process, instrumental, self-concept external, self-concept internal, and goal internalization. These sources of work motivation were associated with Rahim's modes of interpersonal conflict management-dominating, avoiding, obliging, complying, and integrating-and to perceived leadership effectiveness. A structural equation model tested leaders' conflict management styles and leadership effectiveness based upon different sources of work motivation. The model explained variance for obliging (65%), dominating (79%), avoiding (76%), and compromising (68%), but explained little variance for integrating (7%). The model explained only 28% of the variance in leader effectiveness. PMID:16673944

  5. Motivating Action through Fostering Climate Change Hope and Concern and Avoiding Despair among Adolescents

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Efforts to build climate change concern seem warranted to overcome apathy and promote action. However, research suggests that these efforts can backfire by breeding despair, denial and inaction. This may be especially true among younger audiences, as despair is highest among those who view climate challenges as out of their control, and children generally have lower perceived and actual control than adults in political and personal arenas. Though many studies have documented feelings of despair and sadness among younger audiences, few have explored how climate change hope may counteract despair and encourage productive responses to climate change concern. This study examined how climate change hope, despair, and concern predict pro-environmental behavior with a quantitative survey of a random sample of middle school students in North Carolina, USA (n = 1486. We did not find an interaction between climate change hope and concern or despair, but instead found climate change hope and concern independently and positively related to behavior and despair negatively related to behavior. These results suggest that climate change concern among K-12 audiences may be an important antecedent to behavior which does not dampen the positive impacts of hope. Further, rather than mitigating the negative effects of climate change despair, hope may be an independent predecessor to behavior. Students at Title I (a measure of low socioeconomic status schools were less likely to engage in pro-environmental behaviors, suggesting climate literacy efforts should target schools with lower levels of socioeconomic status specifically.

    Motivation is inseparable from human work. It is also one of the five most important elements of the management process. The ability to determine the level of motivation would therefore be very useful in the work of every manager. This paper is an attempt to quantify motivation and evaluate its size, using the concept of entropy. The main reason to try defining a method of measuring the amount of motivation is to improve the management techniques of companies.

  1. How biological microtubules may avoid decoherence

    International Nuclear Information System (INIS)

    Full text: Entangled superpositions persisting for hundreds of milliseconds in protein assemblies such as microtubules (MTs) are proposed in biological functions, e.g. quantum computation relevant to consciousness in the Penrose-Hameroff 'Orch OR' model. Cylindrical polymers of the protein tubulin, MTs organize cell activities. The obvious question is how biological quantum states could avoid decoherence, e.g. in the brain at 37.6 degrees centigrade. Screening/sheelding: tubulin protein states/functions are governed by van der Waals London forces, quantum interactions among clouds of delocalizable electrons in nonpolar 'hydrophobic' intra-protein pockets screened from external van der Waals thermal interactions. Such pockets include amino acid resonance structures benzene and indole rings. (Anesthetic gases erase consciousness solely by interfering with London forces in hydrophobic pockets in various brain proteins). Hence tubulin states may act as superpositioned qubits also shielded at the MT level by counter-ion Debye plasma layers (due to charged C-termini tails on tubulin) and by water-ordering actin gels which embed MTs in a quasi-solid. Biological systems may also exploit thermodynamic gradients to give extremely low effective temperatures. Decoherence free subspaces: paradoxically, a system coupled strongly to its environment through certain degrees of freedom can effectively 'freeze' other degrees of freedom (quantum Zeno effect), enabling coherent superpositions and entanglement to persist. Metabolic energy supplied to MT collective dynamics (e.g. Froehlich coherence) can cause Bose-Einstein condenzation and counter decoherence as lasers avoid decoherence at room temperature. Topological quantum error correction: MT lattice structure reveals various helical winding paths through adjacent tubulins which follow the Fibonacci series. Propagation/interactions of quasi-particles along these paths may process information. As proposed by Kitaev (1997), various

  2. Repeated elicitation of the acoustic startle reflex leads to sensitisation in subsequent avoidance behaviour and induces fear conditioning

    Directory of Open Access Journals (Sweden)

    Janik Vincent M

    2011-04-01

    Full Text Available Abstract Background Autonomous reflexes enable animals to respond quickly to potential threats, prevent injury and mediate fight or flight responses. Intense acoustic stimuli with sudden onsets elicit a startle reflex while stimuli of similar intensity but with longer rise times only cause a cardiac defence response. In laboratory settings, habituation appears to affect all of these reflexes so that the response amplitude generally decreases with repeated exposure to the stimulus. The startle reflex has become a model system for the study of the neural basis of simple learning processes and emotional processing and is often used as a diagnostic tool in medical applications. However, previous studies did not allow animals to avoid the stimulus and the evolutionary function and long-term behavioural consequences of repeated startling remain speculative. In this study we investigate the follow-up behaviour associated with the startle reflex in wild-captured animals using an experimental setup that allows individuals to exhibit avoidance behaviour. Results We present evidence that repeated elicitation of the acoustic startle reflex leads to rapid and pronounced sensitisation of sustained spatial avoidance behaviour in grey seals (Halichoerus grypus. Animals developed rapid flight responses, left the exposure pool and showed clear signs of fear conditioning. Once sensitised, seals even avoided a known food source that was close to the sound source. In contrast, animals exposed to non-startling (long rise time stimuli of the same maximum sound pressure habituated and flight responses waned or were absent from the beginning. The startle threshold of grey seals expressed in units of sensation levels was comparable to thresholds reported for other mammals (93 dB. Conclusions Our results demonstrate that the acoustic startle reflex plays a crucial role in mediating flight responses and strongly influences the motivational state of an animal beyond a short

  5. Characterizing socially avoidant and affiliative responses to social exclusion

    Directory of Open Access Journals (Sweden)

    Katherine Elizabeth Powers

    2012-07-01

    Full Text Available Humans have a fundamental need for social relationships. From an evolutionary standpoint, the drive to form social connections may have evolved as an adaptive mechanism to promote survival, as group membership afforded the benefits of shared resources and security. Thus, rejection from social groups is especially detrimental, rendering the ability to detect threats to social relationships and respond in adaptive ways critical. Previous research indicates that social exclusion alters cognition and behavior in specific ways that may initially appear contradictory. That is, although some studies have found that exclusionary social threats lead to withdrawal from the surrounding social world, other studies indicate that social exclusion motivates affiliative social behavior. Here, we review the existing evidence supporting accounts of avoidant and affiliative responses, and highlight the conditions under which both categories of responses may be simultaneously employed. Then, we review the neuroimaging research implicating specific brain regions underlying the ability to detect and adaptively respond to threats of social exclusion. Collectively, these findings are suggestive of neural system highly attuned to social context and capable of motivating flexible behavioral responses.

    2013-08-09

    The United States is concurrently pursuing the goals of reducing the size of its nuclear weapons force – strategic and non-strategic, deployed and non-deployed – and of modernizing the weapons it continues to possess. Many of the existing systems were deployed 30 to 50 years ago, and the modernization process can be expected to extend over the next decade or more. Given the impossibility of predicting the future over the lifetime of systems that could extend to the end of this century, it is essential that dead ends in force development be avoided, and the flexibility and availability of options be retained that allow for • Scalability downward in the event that further reductions are agreed upon; • Reposturing to respond to changes in threat levels and to new nuclear actors; and • Breakout response in the event that a competitor significantly increases its force size or force capability, In this paper, we examine the current motivations for reductions and modernization; review a number of historical systems and the attendant capabilities that have been eliminated in recent decades; discuss the current path forward for the U.S. nuclear force; provide a view of the evolving deterrence situation and our assessment of the uncertainties involved; and present examples of possibly problematic directions in force development. We close with our thoughts on how to maintain flexibility and the availability of options for which a need might recur in the future.

  7. Personnel Motivation: Essence and Modern Problems

    Directory of Open Access Journals (Sweden)

    Ovsiuk Nina V.

    2014-02-01

    Full Text Available The goal of the article lies in the study of the essence of labour motivation and establishment of differences between stimulation and motivation. While analysing the “motivation” notion the article shows that internal wishes and goals of a human being stimulate this human being to act in a specific direction in order to achieve the set goal. Moreover, the article states that there are two theories of motivation in the modern economic literature – meaningful and procedural. As analysis of indicators of payment for labour in Ukraine shows, there is a rather significant differentiation of sizes of wages by branches of economic activity and there are arrears of wages. These indicators to a certain extent facilitate reduction of motivation of workers for labour activity. In order to increase employment of the population under conditions of the market economy, it is necessary to develop a system of measures for elimination of these problems at the state level and also to reduce to the minimum manifestations of “shadowing” wages.

    Eight studies assessed the motive for sensory pleasure (MSP) involving a general disposition to enjoy and pursue pleasant nature-related experiences and avoid unpleasant nature-related experiences. The stated enjoyment of pleasant sights, smells, sounds, and tactile sensations formed a unitary construct that was distinct from sensation seeking, novelty preference, and need for cognition. MSP was found to be related to (a) enjoyment of pleasant nature scenes and music of high but not low clarity; (b) enjoyment of writings that portrayed highly detailed nature scenes; (c) enjoyment of pleasantly themed paintings and dislike of unpleasant paintings, as distinct from findings with Openness to Experience; (d) choice of pleasant nature scenes over exciting or intellectually stimulating scenes; (e) view duration and memory of artistically rendered quilts; (f) interest in detailed information about nature scenes; and (g) frequency of sensory-type suggestions for improvement of a museum exhibit.

    This study was a preliminarily investigation into the prevention of unintentional doping on the basis of self-determination theory (SDT). Specifically, we examined the relationship between athletes' motives for doping avoidance and their behavior when offered an unfamiliar food product. Participants were young Australian athletes (n = 410) that were offered a free lollipop prior to completing a questionnaire. It was noted whether participants refused to take or eat the lollipop and whether they read the ingredients of the lollipop. The questionnaire assessed autonomous and controlled forms of motivation, amotivation, doping intentions, and adherence regarding doping avoidance behaviors. The results showed that young athletes who adopted controlled reasons to avoid doping in sport (e.g., not getting caught) tended to report higher adherence to behaviors related to avoiding and monitoring banned substances, whereas those who adopted autonomous reasons (e.g., anti-doping being consistent with life goals) appeared to be more willing to read the ingredients of the provided food. The significant interaction effect between autonomous and controlled motivation indicated that autonomous motivation was more predictive to doping intention for athletes with low controlled motivation. It is concluded that SDT may help understand the motivational processes of the prevention of unintentional doping in sport. PMID:25441263

  13. Developmental changes and gender effects on motivational constructs based on the expectancy-value model in Czech and United States students regarding learning of science, mathematics, and other subjects

    Science.gov (United States)

    Yang, Eun-Mi

    This study employed American and Czech student samples to investigate the motivational constructs used in Eccles and Wigfield's (1983) expectancy-value model. To predict achievement behavior, the model specifies relationships among expectancy for-success and task value, task-specific self-concept, perception of task-difficulty, perceptions of social environment, and interpretations and attributions for past events in relation to the social world. Czech and American students (n = 1,145) in grades 4--12 were the participants in this study. The causal relationships among the constructs were tested to investigate structural similarities and differences in the models for both countries. This study also explored developmental changes, gender, and national differences in the students' motivational beliefs for these motivational constructs: Expectancy for Success, Intrinsic Interest Value, Task-specific Self-concept, Perception of Task-difficulty, and Perceived Vocational Gender Dominance for science, mathematics, and other school subjects. The findings indicated that, for both countries, with respect to changes over grade level, compared to the younger students, the older students showed lower motivational beliefs for most subject areas except reading. However, the Czech students in grades 6--8 showed more positive motivational beliefs in life science and social studies than did the Czech students in other grade levels. In comparing genders, the male students exhibited more positive motivational beliefs in physical science than did the female students, and female students showed more positive motivational beliefs in reading than did the male students. For life science, the Czech female students rated Intrinsic Interest Value and Task-specific Self-concept higher than did their peer male students. The American students' motivational beliefs in reading were more positive than were Czech students', and the Czech students held more positive motivational beliefs in life

    International Nuclear Information System (INIS)

    Consider a fixed end pattern (a short self-avoiding walk) that can occur as the first few steps of an arbitrarily long self-avoiding walk on Z/sup d/. It is a difficult open problem to show that as N → ∞, the fraction of N-step self-avoiding walks beginning with this pattern converges. It is shown that as N → ∞, this fraction is bounded away from zero, and that the ratio of the fractions for N and N + 2 converges to one. Similar results are obtained when patterns are specified at both ends, and also when the endpoints are fixed

    A step-through locomotor passive avoidance task is described requiring the suppression of a spontaneous escape reaction from a cool toward a warm compartment in order to avoid an electric shock delivered in the warm side. We observed no lerning of this task at 9 days of age, a very low but significant level of acquisition at 11 days, a slow but progressive improvement of avoidance from the 13th until the 17th day when the adult capacity was achieved, and a marked increase in the rate between 17-20 days.

    2015-01-01

    Persuasion is an important element of human communication. But in many situations, we resist rather than embrace persuasive attempts. Resistance to persuasion has been studied in many different disciplines, including communication science, psychology, and marketing. The present paper reviews and connects these diverse literatures, and provides an organizing framework for understanding and studying resistance. Four clusters of resistance strategies are defined (avoidance, contesting, biased processing, and empowerment), and these clusters are related to different motivations for resisting persuasion (threat to freedom, reluctance to change, and concerns of deception). We propose that, while avoidance strategies may be triggered by any of these motivations, contesting strategies are linked primarily to concerns of deception, while empowerment and biased processing strategies are most common when people are reluctant to change.

    2011-01-01

    This paper introduces a new specialized algorithm for equilibrium Monte Carlo sampling of binary-valued systems, which allows for large moves in the state space. This is achieved by constructing self-avoiding walks (SAWs) in the state space. As a consequence, many bits are flipped in a single MCMC step. We name the algorithm SARDONICS, an acronym for Self-Avoiding Random Dynamics on Integer Complex Systems. The algorithm has several free parameters, but we show that Bayesian optimization can be used to automatically tune them. SARDONICS performs remarkably well in a broad number of sampling tasks: toroidal ferromagnetic and frustrated Ising models, 3D Ising models, restricted Boltzmann machines and chimera graphs arising in the design of quantum computers.

    Full Text Available The aim of this study was to examine the relationship between motivational characteristics and dispositional flow. In order to accomplish this goal, motivational profiles emerging from key constructs within Achievement Goal Theory and Self-Determination Theory were related to the dispositional flow measures. A sample of 413 young athletes (Age range 12 to 16 years completed the PMCSQ-2, POSQ, SMS and DFS measures. Cluster analysis results revealed three profiles: a "self-determined profile" characterised by higher scores on the task-involving climate perception and on the task orientation; a "non-self-determined profile", characterised by higher scores on ego-involving climate perception and ego orientation; and a "low self-determined and low non-self-determined profile" which had the lowest dispositional flow. No meaningful differences were found between the "self-determined profile" and the "non-self-determined profile" in dispositional flow. The "self-determined profile" was more commonly associated with females, athletes practising individual sports and those training more than three days a week. The "non-self-determined profile" was more customary of males and athletes practising team sports as well as those training just two or three days a week

  20. The motivation to express prejudice.

    2015-11-01

    Contemporary prejudice research focuses primarily on people who are motivated to respond without prejudice and the ways in which unintentional bias can cause these people to act in a manner inconsistent with this motivation. However, some real-world phenomena (e.g., hate speech, hate crimes) and experimental findings (e.g., Plant & Devine, 2001, 2009) suggest that some prejudice is intentional. These phenomena and findings are difficult to explain solely from the motivations to respond without prejudice. We argue that some people are motivated to express prejudice, and we develop the Motivation to Express Prejudice Scale (MP) to measure this motivation. In 7 studies involving more than 6,000 participants, we demonstrate that, across scale versions targeted at Black people and gay men, the MP has good reliability and convergent, discriminant, and predictive validity. In normative climates that prohibit prejudice, the internal and external motivations to express prejudice are functionally nonindependent, but they become more independent when normative climates permit more prejudice toward a target group. People high in the motivation to express prejudice are relatively likely to resist pressure to support programs promoting intergroup contact and to vote for political candidates who support oppressive policies. The motivation to express prejudice predicted these outcomes even when controlling for attitudes and the motivations to respond without prejudice. This work encourages contemporary prejudice researchers to give greater consideration to the intentional aspects of negative intergroup behavior and to broaden the range of phenomena, target groups, and samples that they study.

  3. Neuroscientific Model of Motivational Process

    Sung-Il eKim

    2013-03-01

    Full Text Available Considering the neuroscientific findings on reward, learning, value, decision-making, and cognitive control, motivation can be parsed into three subprocesses, a process of generating motivation, a process of maintaining motivation, and a process of regulating motivation. I propose a tentative neuroscientific model of motivational processes which consists of three distinct but continuous subprocesses, namely reward-driven approach, value-based decision making, and goal-directed control. Reward-driven approach is the process in which motivation is generated by reward anticipation and selective approach behaviors toward reward. This process recruits the ventral striatum (reward area in which basic stimulus-action association is formed, and is classified as an automatic motivation to which relatively less attention is assigned. By contrast, value-based decision making is the process of evaluating various outcomes of actions, learning through positive prediction error, and calculating the value continuously. The striatum and the orbitofrontal cortex (valuation area play crucial roles in sustaining motivation. Lastly, the goal-directed control is the process of regulating motivation through cognitive control to achieve goals. This consciously controlled motivation is associated with higher-level cognitive functions such as planning, retaining the goal, monitoring the performance, and regulating action. The anterior cingulate cortex (attention area and the dorsolateral prefrontal cortex (cognitive control area are the main neural circuits related to regulation of motivation. These three subprocesses interact with each other by sending reward prediction error signals through dopaminergic pathway from the striatum and to the prefrontal cortex. The neuroscientific model of motivational process suggests several educational implications with regard to the generation, maintenance, and regulation of motivation to learn in the learning environment.

  6. Why Do People Regulate Their Emotions? A Taxonomy of Motives in Emotion Regulation.

    Tamir, Maya

    2016-08-01

    Emotion regulation involves the pursuit of desired emotional states (i.e., emotion goals) in the service of superordinate motives. The nature and consequences of emotion regulation, therefore, are likely to depend on the motives it is intended to serve. Nonetheless, limited attention has been devoted to studying what motivates emotion regulation. By mapping the potential benefits of emotion to key human motives, this review identifies key classes of motives in emotion regulation. The proposed taxonomy distinguishes between hedonic motives that target the immediate phenomenology of emotions, and instrumental motives that target other potential benefits of emotions. Instrumental motives include behavioral, epistemic, social, and eudaimonic motives. The proposed taxonomy offers important implications for understanding the mechanism of emotion regulation, variation across individuals and contexts, and psychological function and dysfunction, and points to novel research directions.

Our experiences at a land-grant academic institution in assisting researchers in avoiding plagiarism are described. We provide evidence from a university-wide multi-disciplinary course that understanding how to avoid plagiarism in scientific writing is more difficult than it might appear, and that a failure to learn the rules of appropriate citation may cause dire consequences. We suggest that new strategies to provide training in avoiding plagiarism are required. PMID:24785995

Two previous qualitative studies of instructor attitudes found results identical to those from other disciplines, but neither study considered whether instructors perceive student motivation to be more important in certain computing classes. In this work we present quantitative results about the perceived importance of student motivat...

    Adolescents have been reported to be less motivated to engage and remain in substance abuse treatment than adults. When they appear motivated, it is often due to external motivators such as family pressure or court mandated treatment. The purpose of this study was to determine if adolescents’ motivation to change alcohol use was related to treatment engagement while incarcerated and alcohol use after release. Participants (N=114) were youth in a state correctional facility in the Northeast an...

  18. Phase-space picture of resonance creation and avoided crossings

    International Nuclear Information System (INIS)

    Complex coordinate scaling (CCS) is used to calculate resonance eigenvalues and eigenstates for a system consisting of an inverted Gaussian potential and a monochromatic driving field. Floquet eigenvalues and Husimi distributions of resonance eigenfunctions are calculated using two different versions of CCS. The number of resonance states in this system increases as the strength of the driving field is increased, indicating that this system might have increased stability against ionization when the field strength is very high. We find that the newly created resonance states are scarred on unstable periodic orbits of the classical motion. The behavior of these periodic orbits as the field strength is increased may explain why there are more resonance states at high field strengths than at low field strengths. Close examination of an avoided crossing between resonance states shows that the two states exchange their structure, as in bound systems. This phenomenon might lead to interesting effects at certain field strengths

  19. CULTURAL DIMENSIONS AND WORK MOTIVATION IN THE EUROPEAN UNION

    Directory of Open Access Journals (Sweden)

    Matei Mirabela

    2013-07-01

    Full Text Available For decades, the field of work motivation was moulded mainly by the cultural constraints. The present scientific paper is a theoretical research which aims at identifying various motivational patterns which might be used in the EU countries. In order to illustrate these differences, we will use three Hofstede’s cultural dimensions: individualism, uncertainty avoidance and masculinity. Each of these cultural dimensions presents particularities which exert an influence on the way of thinking, on the abilities and behaviours of the individuals in a certain society, but we will refer only at the influence on the attitude towards work. For the identification of the motivational patterns, we will have as starting points, on one side, the particularities of the cultural differences and results of the relevant research performed so far; on the other hand there is Maslow’s hierarchy of needs. Hence, we can consider that safety and security prevails upon other needs where uncertainty avoidance is strong (Greece, Romania and so on. The need of belongingness will prevail upon the need of esteem in the feminine cultures (such as Sweden, Latvia, but in the masculine cultures esteem need is stronger (such as in the case of Hungary. In masculine countries with an increased collectivism (Greece, the opportunities for improvement, recognition and extra incomes will have an increased importance, while in feminine countries (Holland, Sweden personal time, freedom and need for belongingness will be more important. Without claiming to be an exhaustive presentation of the motivational patterns, the purpose of the present paper is to underline the necessity that the motivation theories are to be considered valid only in the cultural environment where they were conceived. The transfer and the application of the motivation theories and patterns from one culture to the other, implies the testing of their validity in the new context.

  20. Critical review: medical students' motivation after failure.

    About 10 % of students in each years' entrants to medical school will encounter academic failure at some stage in their programme. The usual approach to supporting these students is to offer them short term remedial study programmes that often enhance approaches to study that are orientated towards avoiding failure. In this critical review I will summarise the current theories about student motivation that are most relevant to this group of students and describe how they are enhanced or not by various contextual factors that medical students experience during their programme. I will conclude by suggesting ways in which support programmes for students who have encountered academic failure might be better designed and researched in the future. PMID:26443085

  3. Overtraining and exercise motivation: A research prospectus

    Science.gov (United States)

    Hackney, Anthony C.

    1989-01-01

    The problems of exercise overtraining has recently become one of great interest to professionals in the field of human performance assessment. Quite obviously, the ultimate goal of the training process is to improve physical performance. However, excessive training can result in the opposite effect, that is, a performance decline and an impairment in the functional work capacity of the body. Research indicates that both psychological as well as physiological disturbances are quite common in overtrained individuals. For example, psychological changes include increased levels of depression, fatigue, and a lack of motivation. Similarly, impairment of the physiological function of the cardiovascular, metabolic, and endocrine systems also have been found. Some similarities may be found in the psychological and physiological states of crew members exposed to extended space flight and overtrained individuals. Therefore, the possibility exists that the crew members subjected to extended missions in space may develop overstressed or overtrained or both states during their flights. If such states do develop within the crew members, mission performance may be impaired. With these points as a background, the intent is to address potential research directions that NASA may consider viable and of a mutual interest to the researcher. A clear framework by which to begin discussion of research topics is needed; therefore, working definitions of overtraining and exercise motivation are presented. Subsequently, a proposed conceptional model of how exercise overtraining and motivation interact is presented. In support of the proposed model is a brief literature review of relevant areas. Potential research projects are presented and discussed.

    Qualitative study held in an emergency hospital in Aracaju-SE, which aimed to know the perception of nurses about what is a motivated nursing team, to identify possible motivational policies used by them and if they are consistent with the policies proposed by Frederick Herzberg in his theory. Of the 20 nurses participants, the most understood the motivation as a set of techniques possible to shape the behavior of the individual at work, linking it to extrinsic factors and 60% did not consider his team motivated. The types of motivational policies that usually apply realized that these correspond to intrinsic factors aimed at self recovery and self realization of individuals in the tasks running.

  11. Can a near win kindle motivation? The impact of nearly winning on motivation for unrelated rewards.

    Science.gov (United States)

    Wadhwa, Monica; Kim, JeeHye Christine

    2015-06-01

    Common intuition and research suggest that winning is more motivating than losing. However, we propose that just failing to obtain a reward (i.e., nearly winning it) in one task leads to broader, positive motivational effects on subsequent unrelated tasks relative to clearly losing or actually obtaining the reward. We manipulated a near-win experience using a game app in Experiments 1 through 3 and a lottery in Experiment 4. Our findings showed that nearly winning in one task subsequently led participants to walk faster to get to a chocolate bar (Experiment 1), salivate more for money (Experiment 2), and increase their effort to earn money in a card-sorting task (Experiment 3). A field study (Experiment 4) demonstrated that nearly winning led people to subsequently spend more money on desirable consumer products. Finally, our findings showed that when the activated motivational state was dampened in an intervening task, the nearly-winning effect was attenuated. PMID:25940671

    Full Text Available The Impact of Motivation on Employees� Performance and Satisfaction Abstract:The employees� motivation in the workplace was and still is present for many specialists in from the organizational psychology which continues to explore how we relate to our work and what really motivates us. Although literature offers a wide range of definitions in the process of motivation in the end they all converge on the same content. In everyday language, by reasoning it is understood "the why" for which an action is performed. The cause is a compulsion, desire, energy, envy. Meeting the needs will be done in a certain priority, specific to each individual. To be motivated it must be: a goal to be achieved, a direction of action, an excitement state, feelings that will generate efforts to achieve the goal. The most plausible explanation regarding the motivation is given by Anthony Bagshawe said that "motivation is something that drives us to do what we do." Motivation has always been a complex and delicate issue of great subtlety. It consists in discovering and exploitation of the internal resources of people and identification ways to make them work better and to spend energy more efficiently.

    Molecular potential energy surfaces can be actively manipulated by light. This is usually done by strong classical laser light but was recently demonstrated for the quantum field in an optical cavity. The photonic vacuum state of a localized cavity mode can be strongly mixed with the molecular degrees of freedom to create hybrid field-matter states known as polaritons. We simulate the avoided crossing of sodium iodide in a cavity by incorporating the quantized cavity field into the nuclear wave packet dynamics calculation. The quantized field is represented on a numerical grid in quadrature space, thus avoiding the limitations set by the rotating wave approximation (RWA) when the field is expanded in Fock space. This approach allows the investigation of cavity couplings in the vicinity of naturally occurring avoided crossings and conical intersections, which is too expensive in the fock space expansion when the RWA does not apply. Numerical results show how the branching ratio between the covalent and ionic dissociation channels can be strongly manipulated by the optical cavity. PMID:27186666

    The ability of an experimental agent to support conditioned taste/flavor avoidance (CT/FA) in rats often is interpreted as sufficient evidence that the agent produced a state of malaise or nausea. Paradoxically, however, CT/FA also is induced by certain drugs that support conditioned preferences in rats, suggesting that CT/FA is insufficient to reveal a negative hedonic state. The present study tested the hypothesis that the anti-nausea drug ondansetron (OND) would block the ability of nauseo...

    Due to complicated barriers,it is difficult to track the path of the mowing robot and to avoid barriers.In order to solve the problem,a method based on distance-measuring sensors and fuzzy control inputs was proposed.Its track was composed of beelines and was easy to tail.The fuzzy control inputs were based on the front barrier distance and the difference between the left and right barrier distance measured by ultrasonic sensors;the output was the direction angle.The infrared sensors around the robot improved its safety in avoiding barriers.The result of the method was feasible,agile,and stable.The distance between the robot and the barriers could be changed by altering the inputs and outputs of fuzzy control and the length of the beelines.The disposed sensors can fulfill the need of the robot in avoiding barriers.

    Objective The goal of this study was to determine the neural correlates of excessive habit formation in obsessive-compulsive disorder (OCD). We aimed to (i) test for neurobiological convergence with the known pathophysiology of OCD and (ii) infer, based on abnormalities in brain activation, whether these habits arise from dysfunction in the goal-directed or habit system. Method Thirty-seven OCD patients and 33 controls learned to avoid shocks while undergoing a functional Magnetic Resonance Imaging (fMRI) scan. Following 4 blocks of training, we tested if the avoidance response had become a habit by removing the threat of shock and measuring continued avoidance. We tested for task-related differences in brain activity in 3 ROIs, the caudate, putamen and medial orbitofrontal cortex at a statistical threshold of pdifferences in the build up of stimulus-response habits themselves.

    2004-01-01

    This paper presents a novel vision-based obstacle avoidance approach for the Autonomous Mobile Robot (AMR) with a Pan- Tilt-Zoom (PTZ) camera as its only sensing modality. The approach combines the morphological closing operation based on Sobel Edge Detection Operation and the (μ-kσ) thresholding technique to detect obstacles to soften the various lighting and ground floor effects. Both the morphology method and thresholding technique are computationally simple. The processing speed of the algorithm is fast enough to avoid some active obstacles. In addition, this approach takes into account the history obstacle effects on the current state. Fuzzy logic is used to control the behaviors of AMR as it navigates in the environment. All behaviors run concurrently and generate motor response solely based on vision perception. A priority based on subsumption coordinator selects the most appropriate response to direct the AMR away from obstacles. Validation of the proposed approach is done on a Pioneer 1 mobile robot.

    Job motivation is a very important aspect both for employees - as work represents the central area of human activity, since people spend most of their adult life in a state of employment - and for employers, due to the direct implications of motivation on performance. Viewed in the context of work, motivation can be defined as the degree of availability of the employees to become involved in their work and to make sustained effort in order to meet some professional objectives, which can be de...

    Unmanned Aerial System (UAS) applications are growing day by day and this will lead Unmanned Aerial Vehicle (UAV) in the close future to share the same airspace of manned aircraft.This implies the need for UAS to define precise safety standards compatible with operations standards for manned aviation. Among these standards the need for a Sense And Avoid (S&A) system to support and, when necessary, sub¬stitute the pilot in the detection and avoidance of hazardous situations (e.g. midair collis...

    This paper describes an application of Sandia`s non-contact capacitive sensing technology for collision avoidance during the manufacturing of rocket engine thrust chambers. The collision avoidance system consists of an octagon shaped collar with a capacitive proximity sensor mounted on each face. The sensors produced electric fields which extend several inches from the face of the collar and detect potential collisions between the robot and the workpiece. A signal conditioning system processes the sensor output and provides varying voltage signals to the robot controller for stopping the robot.

  20. Self Organization and Self Avoiding Limit Cycles

    Hexner, Daniel; Levine, Dov

    2014-01-01

    A simple periodically driven system displaying rich behavior is introduced and studied. The system self-organizes into a mosaic of static ordered regions with three possible patterns, which are threaded by one-dimensional paths on which a small number of mobile particles travel. These trajectories are self-avoiding and non-intersecting, and their relationship to self-avoiding random walks is explored. Near $\\rho=0.5$ the distribution of path lengths becomes power-law like up to some cutoff le...
