    Interpersonal impression formation is highly consequential for social interactions in private and public domains. These perceptions of others rely on different sources of information and processing mechanisms, all of which have been investigated in independent research fields. In social psychology, inferences about states and traits of others as well as activations of semantic categories and corresponding stereotypes have attracted great interest. On the other hand, research on emotion and reward demonstrated affective and motivational influences of social cues on the observer, which in turn modulate attention, categorization, evaluation, and decision processes. While inferential and categorical social processes have been shown to recruit a network of cortical brain regions associated with mentalizing and evaluation, the affective influence of social cues has been linked to subcortical areas that play a central role in detection of salient sensory input and reward processing. In order to extend existing integrative approaches to person perception, both the inferential-categorical processing of information about others, and affective and motivational influences of this information on the beholder should be taken into account.

    Full Text Available In the past century McClelland (1975 began exploring non-conscious motives and their influence on leader's behaviour. We investigated how leader's intrinsic motivation influences his leadership behaviour, both with managers and entrepreneurs. Our randomized sample included 59 executives employed in Slovenian and international companies with headquarters in Slovenia. We conducted a one hour long structured interview with each individual and asked at least nine of their subordinates to fill in two different questionnaires based on the executive's behaviour under study. Winter's motive scoring system for coding power, affiliation and achievement motives and expressions of responsibility was used to analyse the interviews. The evaluation method proved not to be sufficiently reliable. Factor analysis showed five different styles of leadership: value based leadership, directive leadership, participative leadership, productivity oriented leadership and supportive leadership. Achievement and power motivation are prevailing in entrepreneurs, whereas in managers the leader motivational profile is more often (33% noticed (high power motivation, high concern for the moral exercise of power, and power motivation greater than affiliative motivation. The prediction of influence of unconscious motives presents a smaller part than expected.

  9. Is all motivation good for learning? Dissociable influences of approach and avoidance motivation in declarative memory.

    2011-01-01

    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 navigating to correct locations (approach) or punished for navigating to incorrect platforms (avoidance). Participants' skin conductance levels (SCLs) were recorded during navigation to investigate the role of physiological arousal in motivated learning. Behavioral results revealed that, overall, approach motivation enhanced and avoidance motivation impaired memory performance compared to nonmotivated spatial learning. This advantage was evident across several performance indices, including accuracy, learning rate, path length, and proximity to platform locations during probe trials. SCL analysis revealed three key findings. First, within subjects, arousal interacted with approach motivation, such that high arousal on a given trial was associated with performance deficits. In addition, across subjects, high arousal negated or reversed the benefits of approach motivation. Finally, low-performing, highly aroused participants showed SCL responses similar to those of avoidance-motivation participants, suggesting that for these individuals, opportunities for reward may evoke states of learning similar to those typically evoked by threats of punishment. These results provide a novel characterization of how approach and avoidance motivation influence declarative memory and indicate a critical and selective role for arousal in determining how reinforcement influences goal-oriented learning.

    2016-01-01

    People's preferences for risks have been a subject of interest to researchers in both the economy and psychology fields over the last few years. This has given rise to many important findings about the role of psychological factors that influence people's choices. The presented studies focused on the role of motivational systems (described by Higgins in the Regulatory Focus Theory) in explaining people's financial choices. The main goal was to examine the relationship between people's chronic promotion and prevention motivational system and their propensity to (1) invest, (2) undertake investment risks, and (3) assume financial risks in gambling tasks in both the gain and loss decision-making frame. Moreover, we aimed to investigate how chronic motivational systems confronted with situationally induced promotion and prevention motivation would affect people's propensity to invest and embrace financial risks. Two CAWI studies on a Polish national representative sample (N 1 = 1093; N 2 = 1096) were conducted. The second study consisted of two waves with a 2-week break. The studies provided evidence of higher chronic promotion motivation as well as higher prevention motivation associated with the propensity to invest; however, induced promotion motivation results in a lower propensity to invest compared to induced prevention motivation. Participants with an activated promotion system built more risky portfolios than individuals with an induced prevention system. Moreover, participants with a low chronic promotion system built more risky portfolios than individuals with a high promotion motivation system as long as their prevention system was also low. In terms of gambling decisions in both the gain and loss frame, a higher level of chronic promotion motivation and situationally induced promotion motivation were related to the preference for the non-sure option over the sure one.

  15. Positive emotion, reward, and cognitive control: emotional versus motivational influences

    Directory of Open Access Journals (Sweden)

    Kimberly Sarah Chiew

    2011-10-01

    Full Text Available It is becoming increasingly appreciated that affective influences can contribute strongly to goal-oriented cognition and behaviour. However, much work is still needed to properly characterize these influences and the mechanisms by which they contribute to cognitive processing. An important question concerns the nature of emotional manipulations (i.e., direct induction of affectively-valenced subjective experience versus motivational manipulations (e.g., delivery of performance-contingent rewards and punishments and their impact on cognitive control. Empirical evidence suggests that both kinds of manipulations can influence cognitive control in a systematic fashion, but investigations of both have largely been conducted independently of one another. Likewise, some theoretical accounts suggest that emotion and motivation may modulate cognitive control via common neural mechanisms, while others suggest the possibility of dissociable influences. Here, we provide an analysis and synthesis of these various accounts, suggesting potentially fruitful new research directions to test competing hypotheses.

  2. The influence of extrinsic motivation on competition-based selection.

    Sänger, Jessica; Wascher, Edmund

    2011-10-10

    The biased competition approach to visuo-spatial attention proposes that the selection of competing information is effected by the saliency of the stimulus as well as by an intention-based bias of attention towards behavioural goals. Wascher and Beste (2010) [32] showed that the detection of relevant information depends on its relative saliency compared to irrelevant conflicting stimuli. Furthermore the N1pc, N2pc and N2 of the EEG varied with the strength of the conflict. However, this system could also be modulated by rather global mechanisms like attentional effort. The present study investigates such modulations by testing the influence of extrinsic motivation on the selection of competing stimuli. Participants had to detect a luminance change in various conditions among others against an irrelevant orientation change. Half of the participants were motivated to maximize their performance by the announcement of a monetary reward for correct responses. Participants who were motivated had lower error rates than participants who were not motivated. The event-related lateralizations of the EEG showed no motivation-related effect on the N1pc, which reflects the initial saliency driven orientation of attention towards the more salient stimulus. The subsequent N2pc was enhanced in the motivation condition. Extrinsic motivation was also accompanied by enhanced fronto-central negativities. Thus, the data provide evidence that the improvement of selection performance when participants were extrinsically motivated by announcing a reward was not due to changes in the initial saliency based processing of information but was foremost mediated by improved higher-level mechanisms.

    Personality and motivation have been identified as influential variables associated with foreign language learning; however, few studies have investigated their effect on oral presentations. This study addresses the importance of both personality and motivation in students' collaborative oral presentation performance. A Big Five personality trait questionnaire measuring Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness to Experience, together with the Collaborative Inquiry-based Project Questionnaire measuring Task, Project Work, Reinforcement, Social Learning and Social Pressure motivational constructs were employed to evaluate 257 university students. In general, the results showed that Extraversion, Project Work and Social Pressure were significant correlates of oral presentation scores. The first result suggests that extraverts possess superiority in situations where oral language production is central to communication. This was particularly true for lower-level students, inferring that extraverted personalities can compensate for a lower English language ability. The second indicates that the inquiry-based nature of the assignments was an intrinsic motivator especially valued by extraverts. The third implies that extrinsic motivation was a factor influencing student performance. These findings extend previous research by highlighting the contextual relationships between these affective variables and performance in collaborative oral presentation contexts.

  4. Negative affect varying in motivational intensity influences scope of memory.

    Emotions influence cognitive processes involved in memory. While some research has suggested that cognitive scope is determined by affective valence, recent models of emotion-cognition interactions suggest that motivational intensity, rather than valence, influences these processes. The present research was designed to clarify how negative affects differing in motivational intensity impact memory for centrally or peripherally presented information. Experiments 1 & 2 found that, relative to a neutral condition, high intensity negative affect (anger) enhances memory for centrally presented information. Experiment 3 replicated this effect using another high intensity negative affect (threat). Experiment 4 extended this by finding that, relative to a neutral condition, low intensity negative affect (sadness) enhanced memory for peripherally presented information. Finally, in Experiment 5, the effects of sadness and threat on scope of memory were directly compared, finding that threat narrowed scope of memory, while sadness broadened scope of memory. Together, these results provide additional support for the motivational dimensional model of cognitive scope, in that high intensity emotions narrow cognitive scope, while low intensity emotions broaden cognitive scope.

  5. The implicit affiliation motive moderates cortisol responses to acute psychosocial stress in high school students.

    It has been previously shown that the implicit affiliation motive - the need to establish and maintain friendly relationships with others - leads to chronic health benefits. The underlying assumption for the present research was that the implicit affiliation motive also moderates the salivary cortisol response to acute psychological stress when some aspects of social evaluation and uncontrollability are involved. By contrast we did not expect similar effects in response to exercise as a physical stressor. Fifty-nine high school students aged M=14.8 years were randomly assigned to a psychosocial stress (publishing the results of an intelligence test performed), a physical stress (exercise intensity of 65-75% of HRmax), and a control condition (normal school lesson) each lasting 15min. Participants' affiliation motives were assessed using the Operant Motive Test and salivary cortisol samples were taken pre and post stressor. We found that the strength of the affiliation motive negatively predicted cortisol reactions to acute psychosocial but not to physical stress when compared to a control group. The results suggest that the affiliation motive buffers the effect of acute psychosocial stress on the HPA axis. Copyright © 2014 Elsevier Ltd. All rights reserved.

  6. Motivational Influences on Cognitive Performance in Children: Focus Over Fit.

    Worthy, Darrell A; Brez, Caitlin C; Markman, Arthur B; Maddox, W Todd

    2011-01-01

    Cognitive psychologists have begun to address how motivational factors influence adults' performance on cognitive tasks. However, little research has examined how different motivational factors interact with one another to affect behavior across the lifespan. The current study examined how children perform on a classification task when placed in a regulatory fit or mismatch. Nine-year-old children performed a classification task in which they either gained or lost points for each response. Additionally, children were given either a global promotion focus (trying to earn a gift card) or a prevention focus (trying to avoid losing a gift card). Previous work indicates that adults in this task tend to perform better when there is a match (or fit) between the overall incentive to earn or avoid losing the incentive and the task reward structure to maximize points gained or minimize points lost. Unlike adults, nine-year-olds perform better in the promotion condition than in the prevention condition regardless of task reward structure. Possible explanations for the differences between adults' and children's performance are discussed as well as possible applications for academic settings.

    Full Text Available Despite convincing evidence supporting the association between exercise and positive affect, this complex relationship requires further theoretical and person-centered explanation. The nature of one’s motivation for exercise, as postulated by Self-Determination Theory (SDT, may supply a missing and understudied link. The primary aim of this experimental study was to examine the moderating influence of situational motivation from SDT on the relationship between an acute bout of preferred exercise, namely running (vs. control, and changes in positive affect. Forty-one active women attended two sessions to engage in (a a 30-min moderate-intensity self-paced treadmill run and (b a 30-min quiet activity (i.e., newspaper reading. Participants with high introjection versus those with low introjection reported a greater increase in positive affect from pre- to postrunning and a greater decrease in positive affect from pre- to postcontrol. A “relief from guilt” effect was postulated to explain these results. Motivational variables accounted for 7% of variance in postrun positive affect. Consistent with SDT, running because one values this behavior and its benefits (i.e., identified regulation was significantly associated with postrun positive affect.

    2007-01-01

    Motivation is short-term focused energy. The oldest theories of motivation explain motivated activity as effort to overcome primary deficiencies, such as hunger or boredom. Such theories are difficult to apply because individuals learn idiosyncratic secondary motives as alternative ways of responding to these needs. Three prominent needs theories are discussed: Herzberg's theory of hygiene and motivational factors; McClelland's needs for achievement, power, and affiliation; and Maslow's hierarchy and theory of self-actualization. A second approach to motivation holds that individuals may be thought of as engaging in rational processes to maximize their self-interests. The presented examples of this approach include Vroom's expectancy theory, Adam's theory of inequality, and the Porter-Lawler model that addresses the question of whether satisfaction leads to high performance or vice versa. Finally, several theories of motivation as life orientation are developed.

Purpose: To determine various factors that influence medical graduates choices for residency program. Methods: All applicants for residency program in Mazandaran university of Medical Sciences and Health Services completed the Medical School Graduation Questionnaire, and rated each factor using 0 to 4 Likert-type scale. Factors' ratings were also compared across applicants of different residency program, and demographic variables. Results: The top two factors rated as having strong influences were ones related to interest in helping peop1e (rated 3.07, and intellectual content of the specially (rated 3. Malpractice insurance cost has the least influence (rated 0.98. Most of men preferred independence, whereas most of women preferred predictable working hours. Opportunity to make differences in people's l(fe influenced the specially choices of usual participants. whereas those who used war veterans quota paid more attention to independence and exercise of social responsibility. Patient contact factors were less important to graduates who chose diagnostic speciafties. Also, there was a significant association between the participants' age and four factors. Conclusion: These graduates based their specially preference heavily on the opportunity that the specially affords to help people, and intellectual content of the specially. Knowing the hierarchy of influences on graduates' motivations should help education strategists determine what experiences and perceptions must change if a different mix of specially decision is to result.

    Full Text Available The androgenic adrenal steroids dehydroepiandrosterone (DHEA and 4α-androstenedione (4-A have significant biological activity, but it is unclear if the behavioral effects are unique or only reflections of the effects of testosterone (TS. Gonadally intact male Long-Evans rats were assigned to groups to receive supplements of DHEA, 4-A, TS, corticosteroid (CORT, all at 400 µg steroid/kg of body weight, or vehicle only for 5 weeks. All males were tested in a paradigm for sexual motivation that measures time and urinary marks near an inaccessible receptive female. It was found that DHEA and 4-A supplements failed to influence time near the estrous female in the same way TS supplements did, and, indeed, 5 weeks of 4-A administration reduced the time similar to the suppressive effects of CORT after 3 weeks. Further, animals treated with DHEA or 4-A left fewer urinary marks near an estrous female than TS and control groups. These results suggest that DHEA and 4-A are not merely precursors of sex hormones, and provide support for these steroids influencing the brain and behavior in a unique fashion that is dissimilar from the effects of TS on male sexual behavior.

  15. Seeing future success: does imagery perspective influence achievement motivation?

    Science.gov (United States)

    Vasquez, Noelia A; Buehler, Roger

    2007-10-01

    Imagining future success can sometimes enhance people's motivation to achieve it. This article examines a phenomenological aspect of positive mental imagery--the visual perspective adopted--that may moderate its motivational impact. The authors hypothesize that people feel more motivated to succeed on a future task when they visualize its successful completion from a third-person rather than a first-person perspective. Actions viewed from the third-person perspective are generally construed at a relatively high level of abstraction--in a manner that highlights their larger meaning and significance--which should heighten their motivational impact. Three studies in the domain of academic motivation support this reasoning. Students experience a greater increase in achievement motivation when they imagine their successful task completion from a third-rather than a first-person perspective. Moreover, mediational analyses reveal that third-person imagery boosts motivation by prompting students to construe their success abstractly and to perceive it as important.

    Friendships are essential for adolescent social development. However, they may be pursued for varying motives, which, in turn, may predict similarity in friendships via social selection or social influence processes, and likely help to explain friendship quality. We examined the effect of early adolescents' (N = 374, 12-14 years) intrinsic and extrinsic friendship motivation on friendship selection and social influence by utilizing social network modeling. In addition, longitudinal relations among motivation and friendship quality were estimated with structural equation modeling. Extrinsic motivation predicted activity in making friendship nominations during the sixth grade and lower friendship quality across time. Intrinsic motivation predicted inactivity in making friendship nominations during the sixth, popularity as a friend across the transition to middle school, and higher friendship quality across time. Social influence effects were observed for both motives, but were more pronounced for intrinsic motivation. Copyright © 2010 The Association for Professionals in Services for Adolescents.

    Alcohol-related cues can evoke explicit and implicit motivation to drink alcohol. Concerning the links between explicit and implicit motivation, there are mixed findings. Therefore, we investigated both concepts in 51 healthy 18- to 19-year-old males, who are less affected by neuropsychological deficits in decision-making that are attributed to previous alcohol exposure than older participants. In a randomized crossover design, adolescents were infused with either alcohol or placebo. Self-ratings of alcohol desire, thirst, well-being and alcohol effects comprised our explicit measures of motivation. To measure implicit motivation, we used money and drink stimuli in a Pavlovian conditioning (Pc) task and an Approach-Avoidance Task (AAT). Alcohol administration increased explicit motivation to drink alcohol, reduced Pc choices of alcoholic drink-conditioned stimuli, but had no effect on the AAT. This combination of results might be explained by differences between goal-directed and habitual behavior or a temporary reduction in rewarding outcome expectancies. Further, there was no association between our measures of motivation to drink alcohol, indicating that both self-reported motivation to drink and implicit approach tendencies may independently contribute to adolescents' actual alcohol intake. Correlations between Alcohol Use Disorders Identification Test (AUDIT) scores and our measures of motivation to drink alcohol suggest that interventions should target high-risk adolescents after alcohol intake.

    2010-01-01

    People are motivated to remember past autobiographical experiences related to their current goals; we investigated whether people are also motivated to remember false past experiences related to those goals. In Session 1, we measured subjects' implicit and explicit achievement and affiliation motives. Subjects then rated their confidence about, and memory for, childhood events containing achievement and affiliation themes. Two weeks later in Session 2, subjects received a "computer-generated profile" based on their Session 1 ratings. This profile suggested that one false achievement event and one false affiliation event had happened in childhood. After imagining and describing the suggested false events, subjects made confidence and memory ratings a second time. For achievement events, subjects' explicit motives predicted their false beliefs and memories. The results are explained using source monitoring and a motivational model of autobiographical memory.

  10. Influence of involvement and motivation to correction on product evaluation: Asymmetry for strong and weak brands

    Directory of Open Access Journals (Sweden)

    Styśko-Kunkowska Małgorzata A.

    2014-12-01

    Full Text Available In previous research, studies on motivated correction in the evaluation of branded products are rare. This experimental study with 246 participants examined how the motivation to correct the impact of brand knowledge influences the product evaluation of actual strong and weak brands in low and high involvement situations. As predicted, asymmetry between the strong and weak brands was observed. After the induction of the motivation to correction, the smaller brand effect occurred only in the cases of low involvement and the weak (negative brand. The effect of motivated correction was smaller than the effect of high involvement; therefore, the overall results suggest that conscious explicit motivation to correction evokes correction only in cases of weak brands under certain circumstances. However, this impact is not as strong as the influence of high motivation or a strong brand, even though explicit instructions are given to avoid the negative influence of the brand.

    Vignoles, Vivian L; Regalia, Camillo; Manzi, Claudia; Golledge, Jen; Scabini, Eugenia

    2006-02-01

    Diverse theories suggest that people are motivated to maintain or enhance feelings of self-esteem, continuity, distinctiveness, belonging, efficacy, and meaning in their identities. Four studies tested the influence of these motives on identity construction, by using a multilevel regression design. Participants perceived as more central those identity elements that provided a greater sense of self-esteem, continuity, distinctiveness, and meaning; this was found for individual, relational, and group levels of identity, among various populations, and by using a prospective design. Motives for belonging and efficacy influenced identity definition indirectly through their direct influences on identity enactment and through their contributions to self-esteem. Participants were happiest about those identity elements that best satisfied motives for self-esteem and efficacy. These findings point to the need for an integrated theory of identity motivation.

    2006-04-01

    Client language in favor of change is hypothesized to be a causal mechanism for motivational interviewing (MI), and specific therapist behaviors are prescribed to elicit such speech. This project examined 38 motivational enhancement therapy sessions from Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity), using a sequential behavioral coding system to investigate the relationship between therapist behaviors and client speech. Conditional probabilities were calculated between MI-consistent (MICO) therapist behaviors, MI-inconsistent (MIIN) therapist behaviors, and immediately subsequent client speech. MICO behaviors were more likely to be followed by self-motivational statements, whereas MIIN behaviors were more likely to be followed by client resistance. These results lend support to the importance of therapist behaviors in shaping client speech during MI sessions.

  18. Control and Effort Costs Influence the Motivational Consequences of Choice

    Directory of Open Access Journals (Sweden)

    Holly Sullivan-Toole

    2017-05-01

    Full Text Available The act of making a choice, apart from any outcomes the choice may yield, has, paradoxically, been linked to both the enhancement and the detriment of intrinsic motivation. Research has implicated two factors in potentially mediating these contradictory effects: the personal control conferred by a choice and the costs associated with a choice. Across four experiments, utilizing a physical effort task disguised as a simple video game, we systematically varied costs across two levels of physical effort requirements (Low-Requirement, High-Requirement and control over effort costs across three levels of choice (Free-Choice, Restricted-Choice, and No-Choice to disambiguate how these factors affect the motivational consequences of choosing within an effortful task. Together, our results indicated that, in the face of effort requirements, illusory control alone may not sufficiently enhance perceptions of personal control to boost intrinsic motivation; rather, the experience of actual control may be necessary to overcome effort costs and elevate performance. Additionally, we demonstrated that conditions of illusory control, while otherwise unmotivating, can through association with the experience of free-choice, be transformed to have a positive effect on motivation.

    Full Text Available The purpose of the study was to determine the factors that influence employee motivation in Kenyan Organizations. The study was guided by the following research questions: (i what are the extrinsic factors that influence employee motivation in AMREF Health Africa in Kenya? (ii what intrinsic factors influence employee motivation in AMREF Health Africa in Kenya? A descriptive research design was adopted. Stratified random sampling technique was used to draw a sample size of 96 respondents. The data collection instrument was a structured questionnaire developed by the researchers.  A set of descriptive and correlation statistics were adopted for analysis. The study identified several intrinsic factors that influence employee motivation. These included employee achievements, recognition, work itself, responsibility and advancement, salary structure, the level to which the employees feel appreciated, and the employee perception of their jobs among other factors. The study further, established that the intrinsic factors that influence employee motivation include empowerment and autonomy, employees’ view of their work, organization trust, skill variety requirements among others. The study recommends that the organization should acknowledge and make use of a proper mix of extrinsic and intrinsic factors in their human resource management practices to ensure that employees are well motivated to perform their tasks.

    2015-01-01

    In the present study we examined the moderating effect of the power motive on salivary cortisol responses to acute psychosocial stress and exercise in adolescents. Fifty-seven high school students aged M = 14.8 years participated in the study. The Operant Motive Test was applied to measure the implicit power motive and the Personality Research Form was used to measure the explicit power motive. Salivary cortisol levels were assessed before and after the stress stimuli. Participants were randomly assigned to three experimental groups. An exercise group ran 15 minutes at a defined heart rate of 65-75% HRmax. A psychosocial stress group worked on a standard intelligence test for the same amount of time under the assumption, that their test scores will be made public in class after the test. The control group participated in a regular class session. The implicit power motive was significantly associated with increased cortisol levels in the psychosocial stress group. The explicit power motive was not associated with cortisol responses. Findings suggest that the implicit power motive moderates the cortisol responses to acute stress in an adolescent age group with higher responses to psychosocial stress in comparison to exercise or control conditions.

  7. Acute Stress Influences Neural Circuits of Reward Processing

    Directory of Open Access Journals (Sweden)

    Anthony John Porcelli

    2012-11-01

    Full Text Available People often make decisions under aversive conditions such as acute stress. Yet, less is known about the process in which acute stress can influence decision-making. A growing body of research has established that reward-related information associated with the outcomes of decisions exerts a powerful influence over the choices people make and that an extensive network of brain regions, prominently featuring the striatum, is involved in the processing of this reward-related information. Thus, an important step in research on the nature of acute stress’ influence over decision-making is to examine how it may modulate responses to rewards and punishments within reward-processing neural circuitry. In the current experiment, we employed a simple reward processing paradigm – where participants received monetary rewards and punishments – known to evoke robust striatal responses. Immediately prior to performing each of two task runs, participants were exposed to acute stress (i.e., cold pressor or a no stress control procedure in a between-subjects fashion. No stress group participants exhibited a pattern of activity within the dorsal striatum and orbitofrontal cortex consistent with past research on outcome processing – specifically, differential responses for monetary rewards over punishments. In contrast, acute stress group participants’ dorsal striatum and orbitofrontal cortex demonstrated decreased sensitivity to monetary outcomes and a lack of differential activity. These findings provide insight into how neural circuits may process rewards and punishments associated with simple decisions under acutely stressful conditions.

  8. Exploring the influence of trust relationships on motivation in the health sector: a systematic review.

    Okello, Dickson R O; Gilson, Lucy

    2015-03-31

    Dedicated and motivated health workers (HWs) play a major role in delivering efficient and effective health services that improve patients' experience of health care. Growing interest in HW motivation has led to a global focus on pay for performance strategies, but less attention has been paid to nurturing intrinsic motivation. Workplace trust relationships involve fair treatment and respectful interactions between individuals. Such relationships enable cooperation among HWs and their colleagues, supervisors, managers and patients and may act as a source of intrinsic motivation. This paper presents findings from a qualitative systematic review of empirical studies providing evidence on HW motivation, to consider what these studies suggest about the possible influence of workplace trust relationships over motivation. Five electronic databases were searched for articles reporting research findings about HW motivation for various cadres published in the 10-year period 2003 to 2013 and with available full free text in the English language. Data extraction involved consideration of the links between trust relationships and motivation, by identifying how studies directly or indirectly mention and discuss relevant factors. Twenty-three articles from low- and middle-income countries and eight from high-income countries that met predetermined quality and inclusion criteria were appraised and subjected to thematic synthesis. Workplace trust relationships with colleagues, supervisors and managers, employing organisation and patients directly and indirectly influence HW motivation. Motivational factors identified as linked to trust include respect; recognition, appreciation and rewards; supervision; teamwork; management support; autonomy; communication, feedback and openness; and staff shortages and resource inadequacy. To the authors' knowledge, this is the first systematic review on trust and motivation in the health sector. Evidence indicates that workplace trust

    Little is known about whether acute exercise affects signs or symptoms of attention deficit/hyperactivity disorder (ADHD) in adults. This experiment sought to determine the effects of a single bout of moderate-intensity leg cycling exercise on measures of attention, hyperactivity, mood, and motivation to complete mental work in adult men reporting elevated ADHD symptoms. A repeated-measures crossover experiment was conducted with 32 adult men (18-33 yr) with symptoms consistent with adult ADHD assessed by the Adult Self-Report Scale V1.1. Measures of attention (continuous performance task and Bakan vigilance task), motivation to perform the mental work (visual analog scale), lower leg physical activity (accelerometry), and mood (Profile of Mood States and Addiction Research Center Inventory amphetamine scale) were measured before and twice after a 20-min seated rest control or exercise condition involving cycling at 65% V˙O2peak. Condition (exercise vs rest) × time (baseline, post 1, and post 2) ANOVA was used to test the hypothesized exercise-induced improvements in all outcomes. Statistically significant condition-time interactions were observed for vigor (P Profile of Mood States depression (P = 0.027), fatigue (P = 0.030), and confusion (P = 0.046) scales. No significant interaction effects were observed for leg hyperactivity, simple reaction time, or vigilance task performance (accuracy, errors, or reaction time). In young men reporting elevated symptoms of ADHD, a 20-min bout of moderate-intensity cycle exercise transiently enhances motivation for cognitive tasks, increases feelings of energy, and reduces feelings of confusion, fatigue, and depression, but this has no effect on the behavioral measures of attention or hyperactivity used.

    Using cross-cultural laboratory and field studies with samples of leaders, employees, and students from the United States and the People's Republic of China, we examined how team-level stimuli, including empowering leadership and relationship conflict, combine to influence individual members' motivational states of psychological empowerment and affective commitment. As predicted, we found that these motivational states are individually and jointly influenced by teams' level of empowering leadership and relationship conflict and that these motivational states mediate the relationships between team stimuli and team members' innovative and teamwork behaviors and turnover intentions. In addition, results held despite controlling for team members' nationality and collectivism. We discuss contributions of our study to the team motivation, conflict, and stress literatures.

    In the past decade, the reform of Québec's healthcare establishments has resulted in a reduction in the number of institutions through mergers and closures. In this report, we investigate the consequences of reform by looking at managers' motivations and related mitigating factors. We examine the influence that transformational leaders have on their employees' motivation through organizational justice. Using a survey of 253 healthcare managers, we describe how the positive impact of transformational leadership on motivation is fully mediated via different aspects of organizational justice. The results indicate that while transformational leaders influence each type of organizational justice, followers' motivation is affected primarily by procedural and interpersonal justice and little by distributive justice.

  15. Dissociable influences of reward motivation and positive emotion on cognitive control.

    Science.gov (United States)

    Chiew, Kimberly S; Braver, Todd S

    2014-06-01

    It is becoming increasingly appreciated that affective and/or motivational influences contribute strongly to goal-oriented cognition and behavior. An unresolved question is whether emotional manipulations (i.e., direct induction of affectively valenced subjective experience) and motivational manipulations (e.g., delivery of performance-contingent rewards and punishments) have similar or distinct effects on cognitive control. Prior work has suggested that reward motivation can reliably enhance a proactive mode of cognitive control, whereas other evidence is suggestive that positive emotion improves cognitive flexibility, but reduces proactive control. However, a limitation of the prior research is that reward motivation and positive emotion have largely been studied independently. Here, we directly compared the effects of positive emotion and reward motivation on cognitive control with a tightly matched, within-subjects design, using the AX-continuous performance task paradigm, which allows for relative measurement of proactive versus reactive cognitive control. High-resolution pupillometry was employed as a secondary measure of cognitive dynamics during task performance. Robust increases in behavioral and pupillometric indices of proactive control were observed with reward motivation. The effects of positive emotion were much weaker, but if anything, also reflected enhancement of proactive control, a pattern that diverges from some prior findings. These results indicate that reward motivation has robust influences on cognitive control, while also highlighting the complexity and heterogeneity of positive-emotion effects. The findings are discussed in terms of potential neurobiological mechanisms.

Indeed, behavioral paradigms are emerging that seek to train inhibitory control to improve eating behavior. However, inhibitory control is a multifaceted concept, and it is not yet clear how different types (e.g., reactive motor inhibition, proactive motor inhibition, reward-related inhibition are affected by hunger. Such knowledge will provide insight into the contexts in which behavioral training paradigms would be most effective. The present study explored the impact of promoting a need state (hunger together with motivationally salient distracting stimuli (food/non-food images on inhibitory control in 46 healthy adults. Participants attended two study sessions, once after eating breakfast as usual and once after acute food restriction on the morning of the session. In each session, participants completed questionnaires on hunger, mood and inhibitory control, and undertook task-based measures of inhibitory control, and had physiological measurements (height, weight and blood glucose obtained by a researcher. Acute food restriction influenced task-based assessments but not questionnaire measures of inhibitory control, suggesting that hunger affects observable behavioral control but not self-reported inhibitory control. After acute food restriction, participants showed greater temporal discounting (devaluation of future rewards, and subjective hunger and these were inversely correlated with stop accuracy on the stop signal task. Finally, participants generally responded faster when food-related distractor images were presented, compared to non-food images, independent of state. This suggests that although food stimuli motivate approach behavior, stimulus relevance does not impact inhibitory control in healthy individuals, nor interact with motivational state. These findings may

    Full Text Available This study is intended to find out the influence of the teacher’s competence towards the motivation of students in learning English. A questionnaire was given to 24 students at a sports school in Banda Aceh, Indonesia. The five (5 closed and open questions were adapted from Zhao (2012. The results from this study show that the competences of the teacher including cognitive, affective, and psychomotor competence (Syah, 2013 enhance the motivation of students to learn English. The teacher’s personality also has a strong influence on the students’ perceptions of their teacher. The teacher’s cognitive abilities which include the teacher’s competence at teaching English motivate the students to like English as a subject. Next, the teacher’s affection for the students also influences the students’ motivations who do not only like the subject but to like the teacher. Lastly, the teacher’s way of presenting lessons (psychomotor affect the motivation of the students to learn English. Thus, it can be concluded that the teacher, as one of the external factors, should be able to maximize his/her competence in teaching to motivate the students more when learning English.

  18. Influence of reward motivation on human declarative memory.

    Motivational relevance can prioritize information for memory encoding and consolidation based on reward value. In this review, we pinpoint the possible psychological and neural mechanisms by which reward promotes learning, from guiding attention to enhancing memory consolidation. We then discuss how reward value can spill-over from one conditioned stimulus to a non-conditioned stimulus. Such generalization can occur across perceptually similar items or through more complex relations, such as associative or logical inferences. Existing evidence suggests that the neurotransmitter dopamine boosts the formation of declarative memory for rewarded information and may also control the generalization of reward values. In particular, temporally-correlated activity in the hippocampus and in regions of the dopaminergic circuit may mediate value-based decisions and facilitate cross-item integration. Given the importance of generalization in learning, our review points to the need to study not only how reward affects later memory but how learned reward values may generalize to related representations and ultimately alter memory structure.

    The interest in continuing education (CE) for pharmacists has increased because of patient safety issues, advancing science and the quick changes in the profession. Therefore, contemporary pharmaceutical care requires an effective and sustainable system for pharmacists to maintain and improve competencies. Although motivation plays an important role both as a facilitator (desire to learn) and a barrier (lack of motivation), there is little investigated about this specific factor. The aim of the study was to explore what factors influence pharmacists' participation in CE with a focus on motivation. The theoretical framework was self-determination theory (SDT), which describes autonomous motivation (AM) representing motivation from an internal locus of causality, controlled motivation (CM) originating from an external locus of causality, and relative autonomous motivation (RAM) that measures the AM in an individual after correcting for the CM. The relationship between pharmacists' characteristics, especially their motivation (AM, CM and RAM) in CE, and their participation in CE activities was explored using the AMS-questionnaire and the Dutch online portfolio system. RAM was positively correlated with CE participation of pharmacists and explained 7.8% of the variance. The correlations between the independent variables AM and CM and CE hours were negative (-0.301 and -0.476, respectively). Other factors influencing CE participation were pharmacy school (6.8%), traineeship (10.9%), and work experience (7.8%). Pharmacists participated for 27.0 hours on average in CE during 11 months and preferred face-to-face-learning (85.5%) above e-learning (13.8%). Our findings show a positive relationship between RAM and CE participation. The current CE system is probably not conducive to stimulation of AM. Further research is needed to understand the factors that stimulate pharmacists' motivation and participation in CE.

    Allen, David

    Some informal discussions among educators regarding motivation of students and academic performance have included the topic of magnet schools. The premise is that a focused theme, such as an aspect of science, positively affects student motivation and academic achievement. However, there is limited research involving magnet schools and their influence on student motivation and academic performance. This study provides empirical data for the discussion about magnet schools influence on motivation and academic ability. This study utilized path analysis in a structural equation modeling framework to simultaneously investigate the relationships between demographic exogenous independent variables, the independent variable of attending a science or technology magnet middle school, and the dependent variables of motivation to learn science and academic achievement in science. Due to the categorical nature of the variables, Bayesian statistical analysis was used to calculate the path coefficients and the standardized effects for each relationship in the model. The coefficients of determination were calculated to determine the amount of variance each path explained. Only five of 21 paths had statistical significance. Only one of the five statistically significant paths (Attended Magnet School to Motivation to Learn Science) explained a noteworthy amount (45.8%) of the variance.

    Physical activity behavior is influenced by numerous factors including motivation, social interactions, and the walkability of the environment. To examine how social contexts and environmental features affect physical activity motivational processes across time. Participants (N=104) completed 3 monthly online surveys assessing self-determination theory constructs, social partners in physical activity, neighborhood walkability, and weekly physical activity. Longitudinal path analysis examined the degree to which physical activity was predicted by individual goals, orientation, and autonomy support and whether these associations were meditated by motivation and moderated by the social and environmental contexts of physical activity. The effect of controlled exercise orientations on physical activity was mediated by autonomous motivation. This association was stronger among those who perceived less crime in their neighborhoods. To improve the ability to tailor physical activity counseling it is important to understand how each person views exercise situations and to understand his/her social and neighborhood environments.

    Full Text Available Autonomy, affiliation, and ability appear as main factors that influence online learners‟ motivation and learning outcomes, however, the relative salience of these three factors remains unclear in the online learning literature. Drawing on Deci and Ryan‟s self-determination theory, this study sought to bridge this gap by investigating the relative salience of perceived autonomy, affiliation, and ability on learner motivation and learning outcomes in two special education online programs (N = 262. This study found that the most salient predictor varied from categories of motivation and learning outcomes, and the number of significant predictors increased by participants‟ level of motivation/self-determination. Results of this study provide implications for online learner support.

    When is choice affected by subliminal messages? This question has fascinated scientists and lay people alike, but it is only recently that reliable empirical data began to emerge. In the current paper we bridge the literature on implicit motivation and that on subliminal persuasion. We suggest that motivation in general, and implicit motivation more specifically, plays an important role in subliminal persuasion: It sensitizes us to subliminal cues. To examine this hypothesis we developed a new paradigm that allows powerful tests of subliminal influences as well as stringent assessments of subliminality. The results of two experiments suggest that implicit motivation can enhance the effects of subliminal priming on choice. Copyright © 2012 Elsevier Inc. All rights reserved.

    Michelsen, Carl Christian; Madlener, Reinhard

    2013-01-01

    Heating demand accounts for a large fraction of the overall energy demand of private households in Germany. A better understanding of the adoption and diffusion of energy-efficient and renewables-based residential heating systems (RHS) is of high policy relevance, particularly against the background of climate change, security of energy supply and increasing energy prices. In this paper, we explore the multi-dimensionality of the homeowners’ motivation to decide between competing RHS. A questionnaire survey (N=2440) conducted in 2010 among homeowners who had recently installed a RHS provides the empirical foundation. Principal component analysis shows that 25 items capturing different adoption motivations can be grouped around six dimensions: (1) cost aspects, (2) general attitude towards the RHS, (3) government grant, (4) reactions to external threats (i.e., environmental or energy supply security considerations), (5) comfort considerations, and (6) influence of peers. Moreover, a cluster analysis with the identified motivational factors as segmentation variables reveals three adopter types: (1) the convenience-oriented, (2) the consequences-aware, and (3) the multilaterally-motivated RHS adopter. Finally, we show that the influence of the motivational factors on the adoption decision also differs by certain characteristics of the homeowner and features of the home. - Highlights: ► Study of the multi-dimensionality of the motivation to adopt residential heating systems (RHS). ► Principal component and cluster analysis are applied to representative survey data for Germany. ► Motivation has six dimensions, including rational decision-making and emotional factors. ► Adoption motivation differs by certain characteristics of the homeowner and of the home. ► Many adopters are driven by existing habits and perceptions about the convenience of the RHS

  10. Pharmaceutical Sponsorship Bias Influences Thrombolytic Literature in Acute Ischemic Stroke

    2011-05-01

    Full Text Available Background: The efficacy of thrombolytic therapy for acute ischemic stroke remains controversial in Emergency Medicine and has not been fully endorsed by either the American College of Emergency Physicians or the American Academy of emergency medicine. A growing recognition exists of the influence of pharmaceutical sponsorship on the reported findings of published clinical trials. Sponsorship bias has been suggested as a potential criticism of the literature and guidelines favoring thrombolytic therapy. Objective: The objective of this study is to review the most influential literature regarding thrombolytic therapy for acute ischemic stroke and document the presence or absence of pharmaceutical sponsorship. Methods: A publication-citation analysis was performed to identify the most frequently cited articles pertaining to thrombolytic therapy for acute ischemic stroke. Identified articles were reviewed for disclosures of pharmaceutical funding. Results: Of the 20 most-cited articles pertaining to thrombolytic therapy for acute stroke, 17 (85% disclosed pharmaceutical sponsorship. These disclosures range from general sponsorship to direct employment of authors by pharmaceutical companies. Conclusion: An overwhelming predominance of the most influential literature regarding thrombolytic therapy for acute ischemic stroke is susceptible to sponsorship bias. This potential bias may provide a basis for physician concern regarding the efficacy and safety of thrombolytic therapy. Further, large, independent, placebo-controlled studies may be required to guide therapy and professional guidelines definitively for acute ischemic stroke. [West J Emerg Med. 2011;12(4:435–441.

  12. Influence of motivations for seeking ISO 14001 certification on perceptions of EMS effectiveness in China.

    Fryxell, Gerald E; Lo, Carlos Wing-Hung; Chung, Shan Shan

    2004-02-01

    This study examines the motivations of mainland Chinese facilities in seeking ISO 14001 certification and examines the linkages between these motivations and self-reports of the effectiveness of major environmental management system (EMS) components. In a sample of 128 facilities in Beijing, Shanghai, and Guangzhou, the main drivers for certification were reported to be to ensure regulatory compliance, to enhance the firm's reputation, and to improve environmental performance, in that order. Although motivation to achieve cost reductions were least emphasized, a broad range of motivations appears to be considered in the decision to seek certification to ISO 14001. Regression models linking these motivations to the EMS components suggests that internal motivations have an influence on most EMS components. One interesting exception to this, however, is that no significant relationship was observed between internal motivations and the promulgation of environmental objectives and targets. The relationships associated with external motivations for certification (i.e., those in response to customer and other stakeholder pressures) and EMS components, on the other hand, are weaker and tend to occur earlier in the process cycle. No significant relationships were found between motivations to reduce costs and perceptions of the effectiveness of EMS components. Overall, these findings suggest that ISO 14001, as currently being implemented in mainland China, may have a modestly useful role when used in combination with other policy mechanisms to move the Chinese economy toward more sustainable practices. It is asserted that the ISO standard could provide even greater benefits if Chinese registrars were more proactive in developing EMS in conjunction with even more rigorous third-party audits.

  13. Positive affect and cognitive control: approach-motivation intensity influences the balance between cognitive flexibility and stability.

    Liu, Ya; Wang, Zhenhong

    2014-05-01

    In most prior research, positive affect has been consistently found to promote cognitive flexibility. However, the motivational dimensional model of affect assumes that the influence of positive affect on cognitive processes is modulated by approach-motivation intensity. In the present study, we extended the motivational dimensional model to the domain of cognitive control by examining the effect of low- versus high-approach-motivated positive affect on the balance between cognitive flexibility and stability in an attentional-set-shifting paradigm. Results showed that low-approach-motivated positive affect promoted cognitive flexibility but also caused higher distractibility, whereas high-approach-motivated positive affect enhanced perseverance but simultaneously reduced distractibility. These results suggest that the balance between cognitive flexibility and stability is modulated by the approach-motivation intensity of positive affective states. Therefore, it is essential to incorporate motivational intensity into studies on the influence of affect on cognitive control.

    Contractor, Noshir S; DeChurch, Leslie A

    2014-09-16

    The innovations of science often point to ideas and behaviors that must spread and take root in communities to have impact. Ideas, practices, and behaviors need to go from accepted truths on the part of a few scientists to commonplace beliefs and norms in the minds of the many. Moving from scientific discoveries to public good requires social influence. We introduce a structured influence process (SIP) framework to explain how social networks (i.e., the structure of social influence) and human social motives (i.e., the process of social influence wherein one person's attitudes and behaviors affect another's) are used collectively to enact social influence within a community. The SIP framework advances the science of scientific communication by positing social influence events that consider both the "who" and the "how" of social influence. This framework synthesizes core ideas from two bodies of research on social influence. The first is network research on social influence structures, which identifies who are the opinion leaders and who among their network of peers shapes their attitudes and behaviors. The second is research on social influence processes in psychology, which explores how human social motives such as the need for accuracy or the need for affiliation stimulate behavior change. We illustrate the practical implications of the SIP framework by applying it to the case of reducing neonatal mortality in India.

    2008-06-01

    As the number of blogs increases dramatically, these online forums have become important media people use to share feelings and information. Previous research of blogs focuses on writers (i.e., bloggers), but the influence of blogs also requires investigations from readers' perspectives. This study therefore explores motives for reading blogs and discusses their effects on the responses after reading blogs. According to a factor analysis of 204 respondents in Taiwan, motives for reading blogs consist of affective exchange, information search, entertainment, and getting on the bandwagon. A regression analysis suggests the effects of these motives on three major responses--opinion acceptance, interaction intentions, and word-of-mouth (WOM) intentions--reflect the influence of blogs. Specifically, readers who focus on affective exchanges believe blog messages, interact with bloggers, and spread messages to others. Information search and entertainment motives positively affect opinion acceptance; blog readers who focus on information and those who read for fun both view blogs as trustworthy sources. Getting on the bandwagon also positively influences interaction and WOM intentions; these readers interact with bloggers and transmit messages to others.

    2014-05-01

    Full Text Available Relationships and characteristics that influence consumers’ purchase decision between store brand and manufacturer brand product offerings have emerged as an interesting and practical area of research. From a management perspective, understanding the process by which consumers make purchase choices between these brand offerings would lead to both theoretical and practical applications. Therefore, this study attempts to enhance understanding about the factors that influence consumers’ manufacturer versus store brand purchase decisions. A conceptual model is developed to integrate the manner by which a consumer’s motivation to conform to the perceived social norm of purchasing manufacturer brand products influences this purchase decision. The model is tested using survey data. Findings indicate the importance of the intensity of perceived differences between store brand and manufacturer brand product offerings in affecting consumers’ purchase intention of these products. The relationship is also mediated by consumers’ motivation to conform to manufacturer brand products in their purchase decision.

    Food safety training has been the primary avenue for ensuring food workers are performing proper food handling practices and thus, serving safe food. Yet, knowledge of safe food handling practices does not necessarily result in actual performance of these practices. This research identified participating food service employees' level of agreement with four factors of motivation (internal motivations, communication, reward-punishment, and resources) and determined if respondents with different demographic characteristics reported different motivating factors. Data were collected from 311 food service employees who did not have any supervisory responsibilities. Intrinsic motivation agreement scores were consistently the highest of all four motivational factors evaluated and did not differ across any of the demographic characteristics considered. In contrast, motivation agreement scores for communication, reward-punishment, and resources did differ based on respondents' gender, age, place of employment, job status, food service experience, completion of food handler course, or possession of a food safety certification. In general, respondents agreed that these motivation factors influenced their likelihood to perform various safe food handling procedures. This research begins to illustrate how employees' demographic characteristics influence their responses to various motivators, helping to clarify the complex situation of ensuring safe food in retail establishments. Future research into why employee willingness to perform varies more for extrinsic motivation than for intrinsic motivation could assist food service managers in structuring employee development programs and the work environment, in a manner that aids in improving external motivation (communication, reward-punishment, and resources) and capitalizing on internal motivation.

The focus of this article is on the question of the degree to which the results regarding these motives are influenced and shaped by the applied methods and thesocial context. The empirical basis is a meta-analysis of twelve research examples from the last two decades. It is concluded that the diversity within the results can partly be traced back to fundamental differences in the methodological design, to the absence of detailed theoretical modelling and remarkable differences of the survey instruments and that the role of the social environment and the process of the construction of motives in a certain socialcontext deserve more attention.

    This study examined the influence of treatment motivation on posttreatment effectiveness of an outpatient, individual social skills training for juvenile delinquents imposed as a penal sanction. Propensity score matching was used to match a control group of juveniles receiving treatment as usual ( n = 108 of total N = 354) to a treatment group of juveniles receiving Tools4U, a social skills training with a parental component ( N = 115). Treatment motivation was examined as a moderator and predictor of treatment effects on impulsivity, social perspective-taking, social problem-solving, lack of critical reasoning, developmental task-related skills, and parenting skills. Treatment effects were mostly consistent across juveniles with different levels of treatment motivation. Only one moderating effect was found on active tackling (i.e., actively addressing problems), and predictive effects were found on seeking social support, cognitive empathy, hostile intent attribution, and self-centeredness. Implications for further research are discussed.

    As empirically shown, increasing job satisfaction and motivations correlates with reduced job fluctuation and costs of absenteeism in an organisation. To provide a motivating environment for employees becomes more important in the health-care system and thus also in radiology. The purpose of our study was therefore to evaluate job satisfaction of our team and to define important influencing factors. For data collection, as standardized questionnaire was designed. As a result of a discussion in a focus group, 9 indicators characterizing job satisfaction and motivation were determined (four-point ordinal scale), in addition there were open questions as well as space for comments. The questionnaires were distributed to all employees at the institute during the study period 11/2005. It was assured in the study design that data analysis was anonymous. For statistical analysis, all replies were coded (scale 1-4) and transferred to an excel sheet. Rate of return was 92% (46/50). In general, employees enjoyed work (mean 3.37 +/- 0.5); no significant difference between physicians, technicians and other staff members were observed. Factors most important for personal motivation were good working climate (3.85 +/- 0.4), good reputation of the institute (3.56 +/- 0.8) and personal recognition (3.54 +/- 0.6). Wage raise (3.01 +/- 0.9) and bonus payments (3.11 +/- 0.9) were rated less important. Communication between groups of employees could be improved (2.78 +/- 0.7). When asked, which factors would improve motivation, common answer included teamwork and communication (n = 9), more participation in planning processes (n = 8), more appreciation (n = 7) and continuing education (n = 5). Profound knowledge of factors influencing job satisfaction and motivation of employees allows for the implementation of targeted strategies for continuous improvement.

    Full Text Available Background: Providing and maintaining proper oral hygiene is related with the control of initiation and progression of dental caries and periodontal diseases. Objective: To accentuate on the application and effectiveness of standardized motivational program for oral hygiene in children with assessment of OHI-S Green-Vermillion. Methods: The study includes 200 children from 3 to 6 years of age. Comparison and evaluation of effectiveness of toothpastes with different fluoride concentrations regarding proper hygiene status in children. Application of OHI-S by Green-Vermillion. Examined children are divided into two groups. The first group consists of 100 children divided into two subgroups. The subgroup of children aged from 3 to 5 years washed their teeth with toothpaste containing 500 ppm F. The subgroup of children at the age of 6 used toothpaste containing 1000 ppm F. Concerning the second, control group of 100 children no specific motivation activities were provided. Results: Among children being influenced by standardized motivation program combined with application of toothpaste with 500 ppm F, 45% show better oral hygiene level. Among children influenced by standardized motivation program and toothpaste of 1000 ppm F, 20% of them are with improved oral hygiene status. Reduction of the OHI-S values in children from 3 to 5 years is established from 1.92 to 1.16. In children at the age of 6 OHI-S is reduced from 1.67 to 1.14. Conclusion: 1. All children improve their oral hygiene status after a period of training and motivation. 2. In children at high decay risk standardized motivation program should be combined with additional prophylactic approaches.

    There is an increasing focus in higher education on the role of learner characteristics and their influence on academic performance. Educators are interested in how students engage with learning activities as they progress through the curriculum. A previous study highlighted gender effects in academic performance in student physiotherapists, despite comparable entry scores. The aim of this study was to determine variation in student motivation and engagement, across the four year levels of the physiotherapy program at The University of Notre Dame Australia while considering gender and age. A cross-sectional design was adopted surveying 233 students utilising the Motivation and Engagement Scale - University/College (MES-UC), to review motivational thoughts and behaviours influencing learning. RESULTS identified gender effects with males having on average significantly lower scores for planning, task management and persistence; and higher scores for disengagement from their studies. Females displayed higher average scores for anxiety particularly in their first year and final clinical year. RESULTS were consistent with gender effects noted in academic performance throughout the program for previous student cohorts. The application of the MES-UC early in course would highlight to educators the areas where intervention can be targeted. Early individualized intervention is recommended to address learner characteristics influencing performance.

    Butler, Kyle A.

    The purpose of this study was to determine the influence of scaffolding software on student conceptual understanding and motivation. This study also provides insight on how students use the scaffolding features found in Artemis and the extent to which features show a relationship to student conceptual understanding and motivation. A Randomized Solomon Four Group Design was used in this study. As students worked through a project based unit over photosynthesis, the students performed information seeking activities that were based on their own inquiry. For this purpose, the students in the experimental group used an example of scaffolding software called Artemis, while the students in the control group used a search engine of their choice. To measure conceptual understanding, the researcher analyzed student generated concept maps on photosynthesis using three different methods (quantitative, qualitative, hierarchical). To measure motivation, the researcher used a survey that measured motivation on five different indicators: intrinsic goal orientation, extrinsic goal orientation, task value, control of learning beliefs, self-efficacy for learning and performance. Finally, the researcher looked at the relationship and influence of the scaffolding features on two student performance scores at the end of the unit. This created a total of ten dependent variables in relationship to the treatment. Overall, the students used the collaborative features 25% of the time, the maintenance features 0.84% of the time, the organizational features 16% of the time, the saving/viewing features 7% of the time and the searching features 51% of the time. There were significant correlations between the saving/viewing features hits and the students' task value (r = .499, p motivation.

    Full Text Available INTRODUCTION: Patients usually experience pain during orthodontic treatment. This fact can affect cooperation and the development of treatment. Reporting pain during treatment seems to be influenced by emotional aspects such as the patient's motivation. OBJECTIVE: To assess the relationship between patient's motivation and the intensity of reported pain during two stages of treatment. METHODS: Twenty males (11-37 years old answered a questionnaire divided into five categories regarding their motivation towards treatment. The subjects were studied for 14 days (7 days with bonded brackets and 7 days with the initial arch inserted and the intensity of pain was evaluated on a daily basis. All the issues, including the intensity of pain, were measured through the visual analog scale (VAS. RESULTS: The VAS-associated questionnaire proved to have good temporal reliability and reasonable internal consistency, being that the "perceived severity" domain had the greatest, although not significant (p = 0.196 correlation with pain intensity. Only the question asking the patients if they thought that their teeth were too uneven showed a positive correlation with pain intensity (p = 0.048. CONCLUSION: The results seem to indicate that the five categories related to treatment motivation cannot be used to predict discomfort during treatment. In addition, patients who think their teeth are too uneven may experience more severe pain due to greater force application after insertion of the initial arch.

  1. Modern foraging: Presence of food and energy density influence motivational processing of food advertisements.

    Bailey, Rachel L

    2016-12-01

    More energy dense foods are preferable from an optimal foraging perspective, which suggests these foods are more motivationally relevant due to their greater capability of fulfilling biological imperatives. This increase in motivational relevance may be exacerbated in circumstances where foraging will be necessary. This study examined how food energy density and presence of food in the immediate environment interacted to influence motivational processing of food advertisements. N = 58 adults viewed advertisements for foods varying in energy density in contexts where the advertised food was actually present in the viewing room or not. Advertisements for more energy dense foods elicited greater skin conductivity level compared to ads for less energy dense foods when food was not present. All ads elicited decreases in corrugator supercilii activation indicating positive emotional response resultant from appetitive motivational activation, though the greatest activation was exhibited toward higher energy density foods when food was present. This supports an optimal foraging perspective and has implications for healthy eating interventions. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The manuscript is an evaluative review of the literature pertaining to personal health records (PHRs). The primary focus was on revealing their potential to function as persuasive tools and their efficiency in this role. We demonstrated the ways in which PHRs could motivate, influence, and persuade patients in their adoption of target health behaviors associated with disease and medication management. We based this review on the theoretical framework of captology by B. J. Fogg and colleagues (1998) and the York methodological framework by Arksey and O'Malley (2005). The final sample of studies for review included 22 articles that met eligibility criteria and were retrieved from the SciVerse Scopus database (1999–present). Findings of this review were mixed. Some studies provided evidence that patients found PHRs easy to use and useful. The patients’ self-efficacy and motivation in managing health conditions increased as a result of receiving personalized recommendations, guidance, and decision support generated in PHRs. Other studies, however, demonstrated the PHRs’ lack of efficiency associated with the target behavior change. We explain the mixed findings by access to an unbalanced pool of study designs as well as the breadth of the applied theoretical framework of captology. We suggest future research in a more targeted direction, for example, focusing on the evidence of the efficiency of reminders as means for motivation, influence, and persuasion. PMID:22783154

    Being exposed to good teachers has been shown to enhance students' knowledge and their clinical performance, but little is known about the underlying psychological mechanisms that provide the basis for being an excellent medical teacher. Self-Determination Theory (SDT) postulates that more self-regulated types of motivation are associated with higher performance. Social Cognitive Theory (SCT) focuses on self-efficacy that has been shown to be positively associated with performance. To investigate the influences of different types of teaching motivation, teaching self-efficacy, and teachers' perceptions of students' skills, competencies and motivation on teaching quality. Before the winter semester 2014, physicians involved in bedside teaching in internal medicine at the University Medical Center Hamburg-Eppendorf completed a questionnaire with sociodemographic items and instruments measuring different dimensions of teaching motivation as well as teaching self-efficacy. During the semester, physicians rated their perceptions of the participating students who rated the teaching quality after each lesson. We performed a random intercept mixed-effects linear regression with students' ratings of teaching quality as the dependent variable and students' general interest in a subject as covariate. We explored potential associations between teachers' dispositions and their perceptions of students' competencies in a mixed-effects random intercept logistic regression. 94 lessons given by 55 teachers with 500 student ratings were analyzed. Neither teaching motivation nor teaching self-efficacy were directly associated with students' rating of teaching quality. Teachers' perceptions of students' competencies and students' general interest in the lesson's subject were positively associated with students' rating of teaching quality. Physicians' perceptions of their students' competencies were significantly positively predicted by their teaching self-efficacy. Teaching quality

    Full Text Available Higher education deals with complex knowledge and university teaching should focus on conceptual understanding. Adequate knowledge structures are essential and active knowledge construction should be supported for meaningful learning. But traditional lectures mostly are structured by slides which may misleadingly cause linear representations of knowledge. In this study, a framework for digital concept maps was developed to complement lectures in human biology. The course was aimed at student science teachers at the undergraduate level. The work is based on theoretical research on computer-supported learning, on knowledge structures perspectives within learning environments as well as on self-determination theory. Each session was supplemented by a digital, multimedia-enriched concept map. After each single lecture, students had free access to the concept maps to reinforce the latest topics. The objective of the study was to examine if the use of complementary concept maps (i influences achievement and (ii if motivational variables influence the use of the concept maps. In both cases, influences of computer-user self-efficacy were expected (iii. The students’ (N = 171 concept map use was logged, achievement was tested and motivational variables were surveyed (e.g. interest/ enjoyment, perceived competence, effort/ importance, value/usefulness. The logfile-data allowed distinguishing learners according to their concept map use. Results reveal the benefit of additional concept maps for achievement, positive motivational aspects and computer-user self-efficacy as mediating factors showed some influence. The emphasize of further research should be on students’ active engagement in structuring their individual learning by constructing concept maps themselves, especially in science education courses.

  7. Motivated malleability: Frontal cortical asymmetry predicts the susceptibility to social influence.

    Humans, just as many other animals, regulate their behavior in terms of approaching stimuli associated with pleasure and avoiding stimuli linked to harm. A person's current and chronic motivational direction - that is, approach versus avoidance orientation - is reliably reflected in the asymmetry of frontal cortical low-frequency oscillations. Using resting electroencephalography (EEG), we show that frontal asymmetry is predictive of the tendency to yield to social influence: Stronger right- than left-side frontolateral activation during a resting-state session prior to the experiment was robustly associated with a stronger inclination to adopt a peer group's judgments during perceptual decision-making (Study 1). We posit that this reflects the role of a person's chronic avoidance orientation in socially adjusted behavior. This claim was strongly supported by additional survey investigations (Studies 2a, 2b, 2c), all of which consistently revealed that trait avoidance was positively linked to the susceptibility to social influence. The present contribution thus stresses the relevance of chronic avoidance orientation in social conformity, refining (yet not contradicting) the longstanding view that socially influenced behavior is motivated by approach-related goals. Moreover, our findings valuably underscore and extend our knowledge on the association between frontal cortical asymmetry and a variety of psychological variables.

    2010-02-01

    This paper is a report of a study investigating the motivation of nursing students, their reasons for entering nursing and the perceived influence of others in their decision-making. There is an abundance of research into why students drop out of nursing education, but less well-studied is their motivation for entering it in the first place. In addition, little is known about the role of significant others in their decisions. The participants were a convenience sample of 68 undergraduate nursing students in the second year of their programme. They provided answers to essay topics and the data were analysed using the principles of grounded theory. The data were collected in 2007. Whilst altruism was a major theme in the essays, the opportunities nursing presented were also deemed influential. Personal/self development was viewed as equally important as the desire to care. Family members in the healthcare profession were perceived to be great sources of both emotional and instrumental support. The diversity within nursing and the reported opportunities that nursing presents are important motivators for nursing students, and recruitment campaigns should aim to make these more explicit. There is a need for more qualitative research into indicators of successful nursing students if we are to address not only student dropout, but also to recruit those most likely to complete their education and remain in the nursing profession.

    2015-01-01

    This study investigated the genetic and environmental influences on observed associations between listening comprehension, reading motivation, and reading comprehension. Univariate and multivariate quantitative genetic models were conducted in a sample of 284 pairs of twins at a mean age of 9.81 years. Genetic and nonshared environmental factors accounted for statistically significant variance in listening and reading comprehension, and nonshared environmental factors accounted for variance in reading motivation. Furthermore, listening comprehension demonstrated unique genetic and nonshared environmental influences but also had overlapping genetic influences with reading comprehension. Reading motivation and reading comprehension each had unique and overlapping nonshared environmental contributions. Therefore, listening comprehension appears to be related to reading primarily due to genetic factors whereas motivation appears to affect reading via child-specific, nonshared environmental effects.

    This study aims to examine the influence of inquiry-based instruction on eighth-grade male and female students' motivation and engagement in science learning in two public junior high schools in central Taiwan. Mixed-methods methodology was adopted with 60 students (32 males and 28 females) in the experimental group and 56 students (28 males and 28 females) in the control group. The study lasted for one semester and six units using inquiry-based teaching (90-180 min each) were implemented in the experimental group. Questionnaires used for measuring students' motivation and engagement in science learning were administered as pre- and post-tests. In addition, eight to ten male and female students from both experimental and control groups, as well as two instructors were interviewed four times throughout the semester. Quantitative data were analyzed with t test and the interview data were fully transcribed and coded. Results show that male and female students under intervention expected to do more experiments because it improved their understanding. Male and female students under intervention also used more learning strategies. However, males benefited more than females from the intervention in regard to their motivation and engagement in learning science. Males improved more in motivational constructs, recognized the value of learning science, and increased their cognitive, behavioral, and emotional engagement because what they learned applied to real life. In contrast, females had higher exam anxiety and lower cognitive engagement due to mathematics fear, stronger sense of pride in class, and caring too much about the right answers.

    Prospective memory (PM) is the process associated with the task of realizing delayed intentions in the future. Researchers distinguish two types of PM, namely time-based PM (tbPM) and event-based PM (ebPM). Experiment 1 investigated the developmental trajectory of 3- to 5-year-old preschool children's PM ability, and the occurrence of delayed retrieval (children execute the PM task in a larger window of opportunity) in both tbPM and ebPM tasks. Results revealed that the 5-year-old children outperformed the 3- and 4-year-old children in PM. Moreover, delayed retrieval was more likely to occur in tbPM task than in ebPM task. In Experiment 2, the influence of ongoing task (OT) difficulty on PM performance was investigated with a sample of 5-year-old children. Results revealed no significant effect of OT difficulty on PM performance. In Experiment 3, we improved children's motivation level to complete the OT, then explored the influence of OT difficulty on children's PM performance. Results revealed that the effect of OT difficulty on PM performance became significant after increasing the children's motivation to complete the OT. These results provide insights into the mechanism of attentional resource allocation in PM tasks and have crucial educational and social implications.

    Full Text Available Abstract This study investigates the influence of content-related conditions on adult second language learners’ task motivation during interactive tasks. It also aims to identify what is referred to as interestingness conditions within task content, that is, elements that are intrinsically interesting to most individuals. The investigation was conducted with 38 adult Korean English learners of intermediate proficiency in a conversation course as part of a TESOL certificate program. Using a mixed methods approach to research, results from a task motivation questionnaire, a topic preference questionnaire, and interviews show that content associated with immediate personal life themes such as personal growth, human relationships, and life challenges is perceived to be more intrinsically interesting than that associated with more remote and abstract topics such as those related to global issues and current affairs. Consequently, incorporating life themes into adult-based courses, especially through story-based texts, may act as an important springboard for active motivational engagement during task-based interaction. Résumé Cette étude examine l’influence des conditions, en fonction du contenu, de certaines tâches interactives sur la motivation d’adultes apprenant une langue seconde.

    A student's motivational orientation is considered to be a predictor of a range of related education decisions, from attending classes to choosing a particular course or a profession. This survey study conducted with student volunteers (males = 519; females = 904) enrolled in secondary school science-math academic stream in Thailand investigated the relationship between measures of motivation (achievement goal orientation and physics and biology classroom anxiety) and aspirations for high earning science and math related careers. Results of multiple discriminant analyses showed gender differences in the motivational factors that influence career aspirations. Our interpretation of the findings highlights the significance of cultural beliefs about gender in decision making for careers.

  1. The influences of harmony motives and implicit beliefs on conflict styles of the collectivist.

    Lim, Lena L

    2009-12-01

    The collectivist preference for nonconfrontational conflict styles is usually attributed to the influences of the Confucian value of harmony, which promotes tolerance of interpersonal transgression. Harmony has two distinct motives in collectivistic Asian societies (Leung, 1997 ): harmony enhancement is affective in nature and represents a genuine concern for relationship harmony, while disintegration avoidance is instrumental in nature and sees harmony maintenance as a means to other ends. Hence, as predicted, harmony enhancement is positively related to the use of integrating and compromising, while disintegration avoidance is positively related to the use of avoiding and obliging and is negatively related to the use of integrating during a conflict with a peer in a collectivistic society, Singapore. Besides examining this from a motivational perspective, the study also examines the role of implicit beliefs of personality on one's choice of conflict styles. The two implicit theories of personality refer to the two different assumptions the lay person has about the mutability of personal attributes; an entity theorist believes that personal attributes are fixed and nonmalleable qualities, while an incremental theorist sees personal attributes as qualities that can be developed and changed. Results reveal that incrementalist implicit beliefs also significantly predicted the use of integrating. Harmony enhancement represents a genuine concern for relationship harmony and involves feelings of closeness, unity, and trust. The finding that integrating is predicted by a harmony enhancement motivation suggests the importance of fostering collectivist values of interdependence and feelings of unity and trust so as to encourage the use of integrating to discuss the opposing views openly and constructively. The present study also underscores the benefit of learning an incremental theory to be open to the positive changes in others and work toward improving the relationship

    While motivation to pursue goals is often assumed to be a trait-like characteristic, it is influenced by a variety of situational factors. In particular, recent experiences of success or failure, as well as cognitive responses to these outcomes, may shape subsequent willingness to expend effort for future rewards. To date, however, these effects have not been explicitly tested. In the present study, 131 healthy individuals received either failure or success feedback on a cognitive task. They were then instructed to either ruminate or distract themselves from their emotions. Finally, they completed the Effort Expenditure for Rewards Task, a laboratory measure of reward motivation. Results indicate that participants who received failure feedback relied more strongly on the reward magnitude when choosing whether to exert greater effort to obtain larger rewards, though this effect only held under conditions of significant uncertainty about whether the effort would be rewarded. Further, participants with high levels of trait inhibition were less responsive to reward value and probability when choosing whether to expend greater effort, results that echo past studies of effort-based decision-making in psychological disorders.

    Full Text Available The objective of this paper is to analyze the influence that the internal and external motivations, as well as other factors can suppose for the appearance of the benefits derived from the adherence to the ISO 9001 Standards. For this, it has been made a research centered in The Spanish construction sector. This sector is of great importance at both the global and Spanish level, and ISO 9001 Standard is widespread in it. A questionnaire was sent to 302 companies that are part of this sector, obtaining 126 valid questionnaires, whose data have been treated using a multiple linear regression model. The results of this model indicate that the type of internal or external motivation to implement such a regulation, as well as the seniority in adhering to it, are significant variables for the achievement of the positive results that can be derived from ISO 9001. However, the size of the company is not significant for the appearance of such results.

    Full Text Available Shannon A Morrison, Carol J Dashiff, David E Vance School of Nursing, University of Alabama, Birmingham, AL, USA Abstract: Parental influence to promote autonomy and self-determination in their children as they grow up may also motivate them to exercise and eat healthily. Unfortunately, nutritious dietary consumption and physical activity frequency tend to decline during the adolescent years and reaches its lowest level as the adolescent nears adulthood. In this study of 132 freshman and sophomore college students, the influence of parental autonomy support on overall adolescents self-determination was examined to determine whether self-determination influences adolescents' motivation to engage in healthy diet and exercise behaviors. Utilizing hierarchical multiple regression analyses, parental autonomy support was not predictive of older adolescents' motivation for diet and exercise; however, study results did indicate that parental autonomy support remains highly influential in adolescent self-determination (F[2, 130] = 22.21; P = 0.001 during early college years and that in this sample, adolescent self-determination is predictive of motivation for diet (t = 2.21; P < 0.05, but not exercise. Findings suggest that parental autonomy support continues to influence adolescent internalization of attitudes and behaviors during latter adolescence, but may play a lessor role in motivation for specific health-related behaviors as the adolescent nears adulthood. A better understanding of health motivation antecedents of adolescents may facilitate nurses develop new approaches to health-promotion strategies.

    Full Text Available Considering the importance yet paucity of help-seeking in e-learning, the present study investigated the motivational antecedents of help-seeking among online college students. We explored and compared the influences of achievement approach goals from the old and new achievement motivation models (Elliot & McGregor, 2001; Elliot, Murayama, & Pekrun, 2011 on online students’ help-seeking through intrinsic/extrinsic motivation. Path analyses were used to test two models of help-seeking among college students from four online educational psychology classes (N = 93 based on the two models of achievement goals. Our results showed that the new 3 × 2 model was a better fit than the old 2 × 2 model, suggesting that the achievement approach goals of the new model differ from those of the old model conceptually as Elliot, Murayama, and Pekrun (2011 posited. Second, our results revealed both unexpected direct and indirect positive influence of performance- and other-approach goals on online students’ help-seeking behaviour through extrinsic motivation. Third, while mastery-approach goals indirectly predicted help-seeking through intrinsic motivation, self- and task-approach predicted help-seeking in a dramatically different manner. Self-approach goals displayed indirect influence on help-seeking through intrinsic motivation similar to mastery-approach, yet task-approach displayed a negative direct influence on help-seeking. These results suggested the potential positive impact of self-approach and the detrimental influence of task-approach goals on help-seeking in e-learning environment. Conceptual issues and pedagogical implications for online instructions are discussed.

    2016-12-01

    Idiopathic acute pancreatitis is diagnosed in approximately 10-30 % of cases of acute pancreatitis. While there is evidence to suggest that the cause in many of these patients is microlithiasis, this fact has not been translated into a resource efficient treatment strategy that is proven to reduce recurrence rates. The aim of this study was to examine the value of prophylactic cholecystectomy following an episode of acute pancreatitis in patients with no history of alcohol abuse and no stones found on ultrasound. This was a retrospective study of 2236 patients who presented to a regional Australian hospital. Patients were included when diagnosed with acute pancreatitis with no confirmed cause. Recurrence of acute pancreatitis was compared between those that did and did not undergo cholecystectomy. One hundred ninety-five consecutive patients met the study definition of "idiopathic" acute pancreatitis. 33.8 % (66/195) underwent cholecystectomy. The patients who had cholecystectomy had a recurrence rate of 19.7 % (13/66) whereas, of those managed expectantly, 42.8 % (68/159) had at least one recurrence of acute pancreatitis (P = 0.001). Following an episode of acute pancreatitis with no identifiable cause, in patients fit for surgery, cholecystectomy should be considered to reduce the risk of recurrent episodes of pancreatitis.

    This study investigated whether positive and negative romantic partner social control attempts (persuasion and pressure, respectively) were related to approach-avoidance motives and exercise among young adults ( N = 98), using daily reports. Daily persuasion was linked to higher daily approach motives. At the person level, persuasion was associated with higher approach and avoidance motives in addition to more frequent, longer exercise. Pressure was associated with higher daily relationship stress, which was associated with higher daily avoidance motives. At the person level, pressure was related to less frequent, shorter exercise. Thus, romantic partners' social control use correlates with exercise motives and behavior.

Pre-ex CER and urinary cotinine concentrations of smokers were significantly higher (p<0.05 and p<0.01, respectively compared to that of non-smokers and pre-ex CER concentrations were significantly correlated with cotinine levels in all subjects (p<0.05. Significant (p<0.01 increases were observed in non-HDL oxidation following the exercise in both groups and the elevations were more pronounced in smokers. Pre-ex SOD and GPX activities were not different between the two groups, however post-ex enzyme activities were significantly reduced in smokers (p<0.05. MDA and protein carbonyl concentrations were not different between the two groups and there were not any significant changes due to exercise.In conclusion, according to the results of the present study, we suggest that erythrocyte antioxidants SOD and GPX and plasma non-HDL are more prone to the possible oxidant damage of acute physical exercise in chronic smokers.

    Although previous studies have elucidated associations between motivations for drinking and sex as they relate to risky health outcomes among female college students, the utility of cross-domain motives (i.e., alcohol motives predicting sex-related outcomes and vice versa) in the prediction of specific alcohol- and sex-related behaviors has yet to be examined. The current study examined relations between drinking and sex motives with multiple risky alcohol- and sex-related outcomes (i.e., alcohol consumption, alcohol-related problems, alcohol consumption prior to sexual intercourse, number of sexual partners [vaginal, oral, anal], and emergency contraception use). Multiple structural equation models were used to examine univariate and multivariate associations among drinking and sex motives and specific outcomes in a sample of female undergraduates with lifetime histories of alcohol use and sexual activity (N = 436; 77% White, 21% Hispanic). Findings indicated differential associations between motives and specific outcomes across univariate versus multivariate analyses. Multivariate models indicated greater endorsement of enhancement and less endorsement of intimacy sex motives were significantly associated with heavy drinking and alcohol-related problems, whereas alcohol motives were less reliably linked to sex-related outcomes. When considered simultaneously, sex motives accounted for more variance in some alcohol outcomes relative to certain drinking motives. Cross-domain motives may be useful in predicting risky outcomes among female college students. Research implications include the importance of examining motive-behavior relations in univariate and multivariate contexts. Clinical implications include cross-domain motive assessment and use of emotion regulation strategies to reduce emotionally-motivated maladaptive alcohol- and sex-related behaviors.

    Full Text Available Abstract Background Research on the mal-distribution of health care workers has focused mainly on physicians and nurses. To meet the Millennium Development Goal Five and the reproductive needs of all women, it is predicted that an additional 334,000 midwives are needed. Despite the on-going efforts to increase this cadre of health workers there are still glaring gaps and inequities in distribution. The objectives of this study are to determine the perceived barriers and motivators influencing final year midwifery students’ acceptance of rural postings in Ghana, West Africa. Methods An exploratory qualitative study using focus group interviews as the data collection strategy was conducted in two of the largest midwifery training schools in Ghana. All final year midwifery students from the two training schools were invited to participate in the focus groups. A purposive sample of 49 final year midwifery students participated in 6 focus groups. All students were women. Average age was 23.2 years. Glaser’s constant comparative method of analysis was used to identify patterns or themes from the data. Results Three themes were identified through a broad inductive process: 1 social amenities; 2 professional life; and 3 further education/career advancement. Together they create the overarching theme, quality of life, we use to describe the influences on midwifery students’ decision to accept a rural posting following graduation. Conclusions In countries where there are too few health workers, deployment of midwives to rural postings is a continuing challenge. Until more midwives are attracted to work in rural, remote areas health inequities will exist and the targeted reduction for maternal mortality will remain elusive.

    2016-01-01

    Full Text Available Rationality of decision maker is often reduced by heuristics and biases, and also by different types of external stimuli. In decision-making process individuals simplify phases of information selection and information processing by using heuristics, simple rules which are focused on one aspect of complex problem and ignore other aspects, and in that way 'speed up' decision-making process. This method of making decisions, although efficient in making simple decisions, can lead to mistakes in probability assessment and diminish rationality of decision maker. In that way it can influence drastically on transaction outcome for which decision is being made. The subject of this study is influence of representativeness heuristic on making financial decisions by individuals, and influence of consumption motives on stereotypical elements in information processing phase. Study was conducted by determining attitudes of respondents toward currencies, and then by conducting experiments with aim of analyzing method of making decisions on loan currency. Aim of study was determining whether and to what extent representativeness influence choice of currency in process of making loan decisions. Results of conducted behavioral experiments show that respondents, opposite to rational model, do not asses probability by processing available information and in accordance with their preferences, but by comparing decision objects with other objects which have same attributes, showing in that way moderate positive correlation between stereotypical attitudes and choice of loan currency. Experiments have shown that instrumental motive significantly influence representativeness heuristics, that is, individuals are prone to process information with diminished influence of stereotypical attitudes caused by external stimuli, in situations where there is no so called 'hedonistic decision-making'. Respondents have been making more efficient decisions if they had motive which does

    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

    Positive attitudes toward a new communication technology tend to be a significant motivator in subsequent adoption and use. The recent spurt in the adoption of social media tools such as social networking sites (SNSs) demands the examination of attitudinal variables on motives to use these Web sites. This study explicated a multidimensional measure of attitudes toward SNSs and tested a theoretical model to examine the effect of attitudes on motives to use SNSs and SNS activity. Participants (N=674) completed a cross-sectional survey consisting of measures of attitudes toward SNSs, motives of SNS use, and level of activity. Results showed support for a revised model in which attitudinal variables-ease of use, self-disclosure, and social connection-strongly predicted motives of SNS use such as passing time, information/entertainment, social conformity, and, most importantly, socialization. The motive of using SNSs as a social tool superseded the direct effect of other motives on SNS activity, suggesting that users' primary activity on SNSs was for socialization and for relational development and maintenance.

    Nicotine, the main psychoactive ingredient of tobacco smoke, induces negative motivational symptoms during withdrawal that contribute to relapse in dependent individuals. The neurobiological mechanisms underlying how the brain signals nicotine withdrawal remain poorly understood. Using electrophysiological, genetic, pharmacological, and behavioral methods, we demonstrate that tonic but not phasic activity is reduced during nicotine withdrawal in ventral tegmental area dopamine (DA) neurons, and that this pattern of signaling acts through DA D2 and adenosine A2A, but not DA D1, receptors. Selective blockade of phasic DA activity prevents the expression of conditioned place aversions to a single injection of nicotine in nondependent mice, but not to withdrawal from chronic nicotine in dependent mice, suggesting a shift from phasic to tonic dopaminergic mediation of the conditioned motivational response in nicotine dependent and withdrawn animals. Either increasing or decreasing activity at D2 or A2A receptors prevents the aversive motivational response to withdrawal from chronic nicotine, but not to acute nicotine. Modification of D1 receptor activity prevents the aversive response to acute nicotine, but not to nicotine withdrawal. This double dissociation demonstrates that the specific pattern of tonic DA activity at D2 receptors is a key mechanism in signaling the motivational effects experienced during nicotine withdrawal, and may represent a unique target for therapeutic treatments for nicotine addiction.

    The primary aim of this study was two-fold: 1) to identify salient psychosocial features of the classroom environment that influence students' motivation and self-regulation in science learning; and 2) to examine the effect of the motivational constructs of learning goal orientation, science task value and self-efficacy in science learning on students' self-regulation in science classrooms. Data collected from 1360 science students in grades 8, 9 and 10 in five public schools in Perth, Western Australia were utilized to validate the questionnaires and to investigate the hypothesized relationships. Structural Equation Modeling analysis suggested that student cohesiveness, investigation and task orientation were the most influential predictors of student motivation and self-regulation in science learning. In addition, learning goal orientation, task value and self-efficacy significantly influenced students' self-regulation in science. The findings offer potential opportunities for educators to plan and implement effective pedagogical strategies aimed at increasing students' motivation and self-regulation in science learning.

  13. Motivated Explanation

    Full Text Available 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 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 of 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, combined with an effort to preserve the appearance of accuracy; others enhance epistemic motivation, so that one engages in more careful and thorough generational and evaluative processes. 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.

    Casualty estimation tools are critical in planning for nuclear event scenarios. Current consequence assessment models based on healthy adult males may not adequately represent the population. To develop an understanding of the impact of demographic variables on casualty estimates, human data was surveyed to identify key demographic factors that affect acute radiation response. Information on in utero exposures, gender, age, and comorbidity status was collected from atomic bomb survivors, radiation accidents, and clinical oncology. Burn and trauma studies were also examined to gain insight into the impact of demographic variables on acute injury outcomes. Fetal radiation sensitivity is well documented; increased mortality or malformations are observed depending on gestational age. A greater incidence of radiation syndrome was observed among male atomic bomb survivors. Trauma data show increased mortality in males, apparently due to immunological differences between genders. Limited data suggest vulnerability in the very young and old due to immunological status and comorbidities, respectively. Certain genetically susceptible subpopulations demonstrate marked increased sensitivity to radiation exposure. Interaction of radiation and comorbid conditions has not been well studied; however, burn and trauma data indicate that comorbidities negatively impact response to acute injury. Key factors evaluated together with their prevalence indicate the importance of modeling demographic variability in casualty estimations. Also they can help identify vulnerable subpopulations and provide insight on treatment requirements.

    Full Text Available Background Coffee has been reported to be rich in antioxidants, with both acute and chronic consumption leading to enhanced blood antioxidant capacity. High-fat feeding is known to result in excess production of reactive oxygen and nitrogen species, promoting a condition of postprandial oxidative stress. Methods We tested the hypothesis that coffee intake following a high-fat meal would attenuate the typical increase in blood oxidative stress during the acute postprandial period. On 3 different occasions, 16 men and women consumed a high-fat milk shake followed by either 16 ounces of caffeinated or decaffeinated coffee or bottled water. Blood samples were collected before and at 2 and 4 hours following intake of the milk shake and analyzed for triglycerides (TAG, malondialdehyde (MDA, hydrogen peroxide (H 2 O 2 , and Trolox equivalent antioxidant capacity (TEAC. Results Values for TAG and MDA ( P 0.05. Conclusions Acute coffee consumption following a high-fat milk shake has no impact on postprandial oxidative stress.

    To identify factors influencing the decisions of Malaysian first-year pharmacy undergraduate students in private higher education when choosing to pursue a degree in pharmacy as well as their choice of private university. This cross-sectional study employed a validated, self-administered questionnaire which was administered to 543 first-year pharmacy students from nine different private universities. Factor analysis was utilised to extract key factors from the responses. Descriptive and inferential statistics were used to analyse the data. Eight factors motivating students' decision to study pharmacy emerged from the responses, accounting for 63.8% of the variance observed. Students were primarily motivated by intrinsic interests, with work conditions and profession attributes also exerting significant influence. In terms of choice of private university, nine factors were identified, accounting for 73.8% of the variance observed. The image of the school and university were most influential factors in this context, followed by university safety, programme attributes and financial factors. First-year pharmacy students in the private higher education sector are motivated by intrinsic interest when choosing to study pharmacy over other courses, while their choice of private university is influenced primarily by the image of the school and university. © 2017 Royal Pharmaceutical Society.

    Full Text Available BACKGROUND: Dengue virus (DENV is transmitted by Aedes aegypti, a species that lives in close association with human dwellings. The behavior of DENV-infected mosquitoes needs further investigation, especially regarding the potential influence of DENV on mosquito biting motivation and avidity. METHODOLOGY/PRINCIPAL FINDINGS: We orally challenged 4-5 day-old Ae. aegypti females with a low passage DENV serotype -2 (DENV-2 to test whether the virus influences motivation to feed (the likelihood that a mosquito obtains a blood-meal and the size of its blood meal and avidity (the likelihood to re-feed after an interrupted first blood-meal. To assay motivation, we offered mosquitoes an anesthetized mouse for 2, 3, 4 or 5 minutes 7 or 14 days after the initial blood meals and measured the time they started feeding. 60.5% of the unexposed mosquitoes fed on the mouse, but only 40.5% of the positive ones did. Exposed but negative mosquitoes behaved similarly to unexposed ones (55.0% feeding. Thus DENV-2 infection decreased the mosquitoes' motivation to feed. To assay avidity, we offered the same mosquitoes a mouse two hours after the first round of feeding, and we measured the time at which they started probing. The exposed (positive or negative mosquitoes were more likely to re-feed than the unexposed ones and, in particular, the size of the previous blood-meal that kept mosquitoes from re-feeding was larger in the exposed than in the unexposed mosquitoes. Thus, DENV-2 infection increased mosquito avidity. CONCLUSIONS/SIGNIFICANCE: DENV-2 significantly decreased the mosquitoes' motivation to feed, but increased their avidity (even after taking account the amount of blood previously imbibed. As these are important components of transmission, we expect that the changes of the blood-feeding behaviour impact the vectorial capacity Ae. aegypti for dengue.

    The aim of this study was to describe what verbal behaviours/kinds of talk occur during recorded motivational interviewing sessions between nurses in primary care and their patients. The aim was also to examine what kinds of nurse talk predict patient change talk, neutral talk and/or sustain talk. Motivational interviewing is a collaborative conversational style. It has been shown to be effective, in addressing health behaviours such as diet, exercise, weight loss and chronic disease management. In Sweden, it is one of the approaches to disease prevention conversations with patients recommended in the National Guidelines for Disease Prevention. Research on the mechanisms underlying motivational interviewing is growing, but research on motivational interviewing and disease prevention has also been called for. A descriptive and predictive design was used. Data were collected during 2011-2014. Fifty audio-recorded motivational interviewing sessions between 23 primary care nurses and 50 patients were analysed using Motivational Interviewing Sequential Code for Observing Process Exchanges. The frequency of specific kinds of talk and sequential analysis (to predict patient talk from nurse talk) were computed using the software Generalized Sequential Querier 5. The primary care nurses and patients used neutral talk most frequently. Open and negative questions, complex and positive reflections were significantly more likely to be followed by change talk and motivational interviewing-inconsistent talk, positive questions and negative reflections by sustain talk. To increase patients' change talk, primary care nurses need to use more open questions, complex reflections and questions and reflections directed towards change. © 2016 John Wiley & Sons Ltd.

  20. Hippocampal Homer1 levels influence motivational behavior in an operant conditioning task.

    Directory of Open Access Journals (Sweden)

    Klaus V Wagner

    Full Text Available Loss of motivation and learning impairments are commonly accepted core symptoms of psychiatric disorders such as depression and schizophrenia. Reward-motivated learning is dependent on the hippocampal formation but the molecular mechanisms that lead to functional incentive motivation in this brain region are still largely unknown. Recent evidence implicates neurotransmission via metabotropic glutamate receptors and Homer1, their interaction partner in the postsynaptic density, in drug addiction and motivational learning. As previous reports mainly focused on the prefrontal cortex and the nucleus accumbens, we now investigated the role of hippocampal Homer1 in operant reward learning in the present study. We therefore tested either Homer1 knockout mice or mice that overexpress Homer1 in the hippocampus in an operant conditioning paradigm. Our results show that deletion of Homer1 leads to a diverging phenotype that either displays an inability to perform the task or outstanding hyperactivity in both learning and motivational sessions. Due to the apparent bimodal distribution of this phenotype, the overall effect of Homer1 deletion in this paradigm is not significantly altered. Overexpression of hippocampal Homer1 did not lead to a significantly altered learning performance in any stage of the testing paradigm, yet may subtly contribute to emerging motivational deficits. Our results indicate an involvement of Homer1-mediated signaling in the hippocampus in motivation-based learning tasks and encourage further investigations regarding the specific molecular underpinnings of the phenotypes observed in this study. We also suggest to cautiously interpret the results of this and other studies regarding the phenotype following Homer1 manipulations in animals, since their behavioral phenotype appears to be highly diverse. Future studies would benefit from larger group sizes that would allow splitting the experimental groups in responders and non-responders.

  1. Centrally Administered Ghrelin Acutely Influences Food Choice in Rodents.

    We sought to determine whether the orexigenic hormone, ghrelin, is involved in the intrinsic regulation of food choice in rats. Ghrelin would seem suited to serve such a role given that it signals hunger information from the stomach to brain areas important for feeding control, including the hypothalamus and reward system (e.g. ventral tegmental area, VTA). Thus, in rats offered a choice of palatable foods (sucrose pellets and lard) superimposed on regular chow for 2 weeks, we explored whether acute central delivery of ghrelin (intracerebroventricular (ICV) or intra-VTA) is able to redirect their dietary choice. The major unexpected finding is that, in rats with high baseline lard intake, acute ICV ghrelin injection increased their chow intake over 3-fold, relative to vehicle-injected controls, measured at both 3 hr and 6 hr after injection. Similar effects were observed when ghrelin was delivered to the VTA, thereby identifying the VTA as a likely contributing neurobiological substrate for these effects. We also explored food choice after an overnight fast, when endogenous ghrelin levels are elevated, and found similar effects of dietary choice to those described for ghrelin. These effects of fasting on food choice were suppressed in models of suppressed ghrelin signaling (i.e. peripheral injection of a ghrelin receptor antagonist to rats and ghrelin receptor (GHSR) knock-out mice), implicating a role for endogenous ghrelin in the changes in food choice that occur after an overnight fast. Thus, in line with its role as a gut-brain hunger hormone, ghrelin appears to be able to acutely alter food choice, with notable effects to promote "healthy" chow intake, and identify the VTA as a likely contributing neurobiological substrate for these effects.

    Full Text Available The scientific literature provides empirical evidence on the relationship between school engagement and numerous important variables of the adolescents’ educational context. The school engagement has been related, among other important constructs, with burnout of both teachers and students, school performance, satisfaction with the school, behavioral disruption, goal orientation and motivational climate in the classroom. Because of it, the aim of this study was to analyze the relationship between perceived motivational class climate and students’ academic achievement, with school engagement acting as a mediator. A sample of 2028 teenagers completed various instruments to measure the perception of motivational climate, perceived basic psychological needs satisfaction, perceived autonomy support provided by the teacher, and academic achievement. The data were analyzed using a structural equation model with observed variables (path analysis. The results have shown a significant relationship between motivational climate and school engagement, and of this with academic achievement. It should also be highlighted the direct relationship of perceived competence and perceived autonomy support with perception of academic success. Of the three variables to be predicted (Portuguese and Mathematics marks and Academic success, the largest percentage of variance explained was the one of academic success. The results are discussed within the framework of achievement goal theory, the self-determined motivation, and in terms of contributing practical issues to adolescents’ teaching-learning process.

    Full Text Available In the light of the poor academic achievement in science by secondary school students in South Africa, students' motivation for science learning should be enhanced. It is argued that this can only be achieved with insight into which motivational factors to target, with due consideration of the diversity in schools. The study therefore explored the impact of six motivational factors for science learning in a sample of 380 Grade Nine boys and girls from three racial groups, in both public and independent schools. The students completed the Student Motivation for Science Learning questionnaire. Significant differences were identified between different groups and school types. The study is important for identifying the key role of achievement goals, science learning values and science self-efficacies. The main finding emphasises the significant role played by science teachers in motivating students for science in terms of the learning environments that they create. This has important implications for future research, aimed at a better understanding of these environments. Such insights are needed to promote scientific literacy among the school students, and so contribute to the improvement of science achievement in South Africa.

    Recruitment and retention of allied health professionals (AHPs) to remote and rural Australia is challenging and correlates with poorer health status of remote and rural residents. While much has been written about the recruitment and retention problem, this study took a new approach by reviewing the literature describing the motivation of AHPs to work in remote and rural areas and then analyzing the findings from the perspective of motivation theory using Herzberg's extrinsic and intrinsic classification. Intrinsic motivation incentives are known to contribute to job satisfaction and come from within the individual, for example the pleasure derived from autonomy or challenge at work. In contrast, extrinsic motivation incentives are provided by the job and include such factors as salary and professional development provisions. Extrinsic incentives are important because they prevent job dissatisfaction. Job satisfaction has been shown to be linked with increased retention. Thirty-five articles, including 26 from Australia, met the inclusion criteria. The key findings related to motivation from each article are outlined and the results classified into the extrinsic-intrinsic framework. The incentives are then further analyzed as having a positive or a negative influence. In total, 38 different incentives were described a total of 246 times. Of the total, almost half (n=115) comprised extrinsic incentives with a negative influence, with poor access to professional development, professional isolation and insufficient supervision the most frequently reported. Rural lifestyle and diverse caseloads were the most frequently mentioned positive extrinsic incentives, while autonomy and community connectedness were the most cited positive intrinsic incentives. Negative intrinsic incentives were mentioned least frequently (n=18); however, of these, feeling overwhelmed and that your work was not valued by the community were the most commonly reported. The results demonstrate the

    Ischemic heart disease presents different features in men and women. We analyzed the relation between gender and prognosis in patients who had suffered a high-risk acute coronary syndrome (ACS). This was a prospective analytical cohort study performed at Lozano Blesa University Hospital, Zaragoza, Spain, of 559 patients diagnosed with high-risk ACS with and without ST-segment elevation according to the American College of Cardiology/American Heart Association guidelines. The sample was divided into two groups by gender and differences in epidemiologic, laboratory, electrocardiographic and echocardiographic variables and treatment were recorded. A Cox's proportional hazard model was applied and 6-month mortality was analyzed as the main variable. The median age was 65.2±12.7 years, and 21.8% were women. Baseline characteristics in women were more unfavorable, with higher GRACE scores, older age, higher prevalence of hypertension, diabetes and heart failure, lower ejection fraction and more renal dysfunction at admission. Women suffered more adverse cardiovascular events (27.9% vs. 15.8%, p=0.002). Sixty-four patients died, 18.9% of the women vs. 9.4% of the men (p=0.004). After multivariate analysis, female gender did not present an independent relation with mortality. Hemoglobin level, renal function, ejection fraction and Killip class >1 presented significant differences. Acute syndrome coronary in women has a worse prognosis than in men. Their adverse course is due to their baseline characteristics and not to their gender. Copyright © 2012 Sociedade Portuguesa de Cardiologia. Published by Elsevier España. All rights reserved.

    Full Text Available Intramural programs provide competition and recreation during the academic year for the diverse college populations of faculty, staff, and currently enrolled students and their spouses/partners who do not participate in other organized sports on campus. Sport psychologists, physical activity leaders, and others have shown an increased interest in the psychological factors that motivate college students to consume sport and physical activity (Rickel, Stoll, &Beller, 2005, 2006; Harkema, Dieser, Lankford, & Scholl, 2006; Yue-de, Wen-hao, & Ying-chun, 2009. Little research has been done with regard to the motivational factors affecting individuals’ decisions about participating specifically in intramural sports such as flag football, basketball, and soccer, etc. The purpose of this study was to independently test the measurement model of the Participant Motivations Questionnaire (PMQ assumed to underlie the motivational factors of the intramural sport participation by male and female college students. In addition, this study also examined whether or not PMQ was valid for the intramural sport participants in a northwestern university of the USA. Based on the results of the CFA, the one-factor model does fit both male and female college students. However, the factor loadings are not equivalent across the two groups. In summary, it is noted that the regenerated 24-item PMQ for the intramural sport participants is unequally valid for the current subjects of male and female college students.

    2006-02-01

    In this study, we examined participants' responses to motivational asynchronous music by isolating rhythmical properties and exploring personality correlates. Fifty-eight physically active participants (41 men and 17 women) aged 22.3 +/- 6.4 years performed an isometric weight-holding task on three occasions while being randomly exposed to no music, rhythm and motivational music. The rhythm and music conditions were edited portions of the same musical selection and had identical fast tempi, although the rhythm condition contained no melody, harmonies or lyrics. Participants each completed a copy of Cattell's 16PF following the third and final trial. A repeated-measures analysis of variance found the participants held the weight suspended for significantly longer when listening to motivational music in comparison to rhythm or no music. When listening to rhythm, participants endured the task for significantly longer than when listening to no music. The response to music was found to be significantly related to liveliness, while sensitivity correlated with responses to music factors (harmony, melody, lyrics, etc.) not present in the rhythm condition. These results suggest that responses to motivational music are subtle in nature and are determined by both musical factors and individual characteristics, and potentially an interaction between the two.

    2013-10-01

    This study examined a three-step adaptation of the Theory of Planned Behaviour (TPB) applied to the intention of consumers to purchase sustainably sourced food. The sample consisted of 137 participants, of which 109 were female, who were recruited through a farmers market and an organic produce outlet in an Australian capital city. Participants completed an online questionnaire containing the TPB scales of attitude, subjective norms, perceived behavioural control and intention; measures of positive moral attitude and ethical self identity; and food choice motives. Hierarchical multiple regression was used to examine the predictive utility of the TPB in isolation (step 1) and the TPB expanded to include the constructs of moral attitude and ethical self-identity (step 2). The results indicated the expansion of the TPB to include these constructs added significantly to the predictive model measuring intention to purchase sustainably sourced food. The third step in the adaptation utilised this expanded TPB model and added a measure of retail channel (where consumers reported buying fresh produce) and 9 food choice motives, in order to assess the predictive utility of the inclusion of choice motivations in this context. Of the 8 food choice motives examined, only health and ethical values significantly predicted intention to purchase sustainably sourced food. However, with the addition of food choice motives, ethical self-identity was no longer a significant predictor of intention to purchase sustainably sourced food. Overall the adapted TPB model explained 76% of the variance in intention to purchase sustainably sourced food. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Introduction. The aim of the present study was to investigate whether a 12-hour exposure in a normobaric hypoxic chamber would induce changes in the hemostatic system and a procoagulant state in volunteers suffering from acute mountain sickness (AMS and healthy controls. Materials and Methods. 37 healthy participants were passively exposed to 12.6% FiO2 (simulated altitude hypoxia of 4,500 m. AMS development was investigated by the Lake Louise Score (LLS. Prothrombin time, activated partial thromboplastin time, fibrinogen, and platelet count were measured and specific methods (i.e., thromboelastometry and a thrombin generation test were used. Results. AMS prevalence was 62.2% (LLS cut off of 3. For the whole group, paired sample t-tests showed significant increase in the maximal concentration of generated thrombin. ROTEM measurements revealed a significant shortening of coagulation time and an increase of maximal clot firmness (InTEM test. A significant increase in maximum clot firmness could be shown (FibTEM test. Conclusions. All significant changes in coagulation parameters after exposure remained within normal reference ranges. No differences with regard to measured parameters of the hemostatic system between AMS-positive and -negative subjects were observed. Therefore, the hypothesis of the acute activation of coagulation by hypoxia can be rejected.

    Obesity is linked to numerous diseases including heart disease, diabetes, and cancer. To address this issue, food and beverage manufacturers as well as health organizations have developed nutrition symbols and logos to be placed on the front of food packages to guide consumers to more healthful food choices. In 2010, the U.S. Food and Drug Administration requested information on the extent to which consumers notice, use, and understand front-of-package nutrition symbols. In response, this study used eye-tracking technology to explore the degree to which people pay visual attention to the information contained in food nutrition labels and front-of-package nutrition symbols. Results indicate that people with motivation to shop for healthful foods spent significantly more time looking at all available nutrition information compared to people with motivation to shop for products on the basis of taste. Implications of these results for message design, food labeling, and public policy are discussed.

    Submicrorepresentations (SMRs) are a powerful tool for identifying misconceptions of chemical concepts and for generating proper mental models of chemical phenomena in students' long-term memory during chemical education. The main purpose of the study was to determine which independent variables (gender, formal reasoning abilities, visualization abilities, and intrinsic motivation for learning chemistry) have the maximum influence on students' reading and drawing SMRs. A total of 386 secondary school students (aged 16.3 years) participated in the study. The instruments used in the study were: test of Chemical Knowledge, Test of Logical Thinking, two tests of visualization abilities Patterns and Rotations, and questionnaire on Intrinsic Motivation for Learning Science. The results show moderate, but statistically significant correlations between students' intrinsic motivation, formal reasoning abilities and chemical knowledge at submicroscopic level based on reading and drawing SMRs. Visualization abilities are not statistically significantly correlated with students' success on items that comprise reading or drawing SMRs. It can be also concluded that there is a statistically significant difference between male and female students in solving problems that include reading or drawing SMRs. Based on these statistical results and content analysis of the sample problems, several educational strategies can be implemented for students to develop adequate mental models of chemical concepts on all three levels of representations.

    Full Text Available The Model of Motivational Dynamics (MMD; Skinner and Pitzer, 2012 infers that peers influence behavioral engagement levels, which in turn is linked to coping and resilience. Scholars, however, are yet to test the MMD among an athletic population. The purpose of this paper was to assess an a priori model that included key constructs from the MMD, such as resistance to peer influence, behavioral engagement and disaffection, coping, and resilience among athletes. Three hundred and fifty-one athletes (male n = 173, female n = 178; M age = 16.15 years completed a questionnaire that measured each construct. Our results provide support for the model. In particular, there were positive paths between resistance to peer influence and behavioral engagement, behavioral engagement and task-oriented coping, and task-oriented coping with resilience. There was also a positive path between resilience and resistance to peer influence, but a negative path from resistance to peer influence to behavioral disaffection. Due to the reported benefits of enhancing resistance to peer influence and behavioral engagement, researchers could devise sport specific interventions to maximize athletes’ scores in these constructs.

    An extensive literature documents a close association between cigarette and alcohol use. The joint pharmacological effects of alcohol and nicotine on smoking and drinking motivation may help explain this relationship. This experiment was designed to test the separate and combined pharmacological effects of nicotine and a low dose of alcohol (equivalent to 1-2 standard drinks) on substance use motivation using a double-blind and fully crossed within-subjects design. Participants (N = 87) with a wide range of smoking and drinking patterns completed 4 counterbalanced experimental sessions during which they consumed an alcohol (male: 0.3g/kg; female: 0.27g/kg) or placebo beverage and smoked a nicotine (.6 mg) or placebo cigarette. Outcome measures assessed the impact of drug administration (alcohol or nicotine) on craving to smoke, craving to drink, affect, and liking of the beverage and cigarette. Results indicated that combined administration produced higher cravings to smoke for the entire sample, as well as higher cravings to drink among women and lighter drinkers. Heavier users of either alcohol or cigarettes also exhibited enhanced sensitivity to the effects of either drug in isolation. Separate, but not interactive, effects of alcohol and nicotine on mood were observed as well as both same-drug and cross-drug effects on beverage and cigarette liking. Together, these findings support the notion that the interactive pharmacological effects of nicotine and low doses of alcohol play an important role in motivating contemporaneous use and suggest roles for cross-reinforcement and cross-tolerance in the development and maintenance of alcohol and nicotine use and dependence.

    Prospective memory (PM) is the process associated with the task of realizing delayed intentions in the future. Researchers distinguish two types of PM, namely time-based PM (tbPM) and event-based PM (ebPM). Experiment 1 investigated the developmental trajectory of 3- to 5-year-old preschool children’s PM ability, and the occurrence of delayed retrieval (children execute the PM task in a larger window of opportunity) in both tbPM and ebPM tasks. Results revealed that the 5-year-old children outperformed the 3- and 4-year-old children in PM. Moreover, delayed retrieval was more likely to occur in tbPM task than in ebPM task. In Experiment 2, the influence of ongoing task (OT) difficulty on PM performance was investigated with a sample of 5-year-old children. Results revealed no significant effect of OT difficulty on PM performance. In Experiment 3, we improved children’s motivation level to complete the OT, then explored the influence of OT difficulty on children’s PM performance. Results revealed that the effect of OT difficulty on PM performance became significant after increasing the children’s motivation to complete the OT. These results provide insights into the mechanism of attentional resource allocation in PM tasks and have crucial educational and social implications. PMID:28203212

    The study investigates whether the motivation for obtaining a pension together with written instructions change the response bias in symptom scales as well as symptom validity test. 80 warned and 91 unwarned claimants for disability pension due to a mental illness were recruited. Participants completed a socio-demographic questionnaire (with statements to measure motivation), the module A of the HEALTH-49 as well as the SIMS. ANOVAs (analysis of variance) showed that warned claimants had significantly higher scores in total assets in symptom scales of the HEALTH-49 as well as the SIMS compared to the unwarned claimants. Warned persons showed higher odds for an invalid value in the SIMS. A regression analysis revealed that the item "retirement means for me a chance to be healthy" can predict the criterion total score of the SIMS. Warnings may produce negative response bias in symptom scales. Patients made negative response bias when they hope to recover through their pension. © Georg Thieme Verlag KG Stuttgart · New York.

    2015-05-01

    Full Text Available This study examined value-added intentions by manipulating the cognitive frame associated with monetary contingencies for detecting prospective memory cues. We associated a loss-frame with a monetary punishment for failing to respond to cues and a gain-frame with a monetary reward for remembering to respond to cues and compared those frames to a no-frame control condition with no contingency linked to performance. Across two experiments, we find increased prospective memory performance for participants in the loss-frame (Experiments 1 and 2 and in the gain-frame (Experiment 2 conditions relative to the no-frame condition. This value-related improvement in prospective memory was not accompanied by a significant increase in cue monitoring as measured by intention induced interference to an ongoing task and recognition memory for ongoing task items. The few previous studies investigating motivational prospective memory showed mixed results regarding whether prospective memory improves due to incentives or not. Our results provide further evidence that, under some experimental conditions, prospective memory improves with rewards and that the benefit generalizes to penalizing performance. The results have both practical implications and theoretical implications for motivation models of prospective memory.

    The aim of this study was to examine the potential motivational and behavioural benefits of two peer tutoring programmes for tutors in a sport setting. Differences between the sexes were also explored. Thirty two college-age males and females, all novices on a French boxing task, were assigned to a 2 x 2 [sex x training type: physical practice associated with trained peer tutoring (TPT) vs physical practice associated with untrained peer tutoring (UPT)] factorial design. All participants were given six French boxing lessons of 2 h each. The TPT programme included structured methods to prepare the participants to fulfil their role of tutors, whereas the UPT programme did not. The results demonstrated that the TPT programme resulted in higher scores for coaching skills. Furthermore, interaction effects revealed that the TPT programme yielded better offensive outcomes for males and better defensive outcomes for females. Although the UPT participants expressed higher self-efficacy, no differences emerged for intrinsic motivation and causal attributions. Finally, male tutors displayed higher self-efficacy and offensive outcomes than female tutors. The results are discussed in the light of previous findings in the educational and sport psychology literature.

    In this study, the relationships among students’ cognitive/motivational variables, cognitive conflict, and conceptual change were investigated. Subjects were 159 seventh graders in Korea. Tests regarding logical thinking ability, field dependence/independence (FDI), meaningful learning approach, failure tolerance, mastery goal orientation, and self-efficacy were administered to examine students’ cognitive/motivational characteristics. A preconception test and a test of responses to discrepant event were also conducted to examine the degree of students’ cognitive conflict induced by a discrepant event. Computer-assisted instruction, designed to change an undifferentiated weight-density concept into a scientific density concept, was then provided to students as a conceptual change intervention. A conception test was administered as a post-test. The results indicated that FDI was the only statistically significant variable correlated with the degree of cognitive conflict. A stepwise multiple regression analysis revealed that logical thinking ability, FDI, and failure tolerance were statistically significant predictors of the conception test scores. Educational implications are discussed.

    Full Text Available The present study was carried out to investigate the influence of mathematics self-concept (MSC, motivation to learn mathematics (SMOT and self-regulation learning (SRL on students' mathematics academic achievement. This study is of a descriptive survey type. 300 female students at the first grade of high school (the second period in City Qods, were selected by multiple step cluster sampling method and completed MSC, SMOT and SRL questionnaires. Mathematics academic achievement was measured by mathematics scores in the first semester of 1393-94 education year. Results obtained by data analysis indicated that the primary conceptual model of the research was an appropriate model and possesses good fitness. Therefore, influence of mathematics self-concept, motivation to learn mathematics and self-regulation learning on mathematics academic achievement was confirmed. On the other hand, it was revealed that mathematics self-concept had influence on motivation to learn mathematics, and motivation to learn mathematics had effect on self-regulation learning. Compared to motivation to learn mathematics and self-regulation learning, mathematics self-concept was a stronger predictor for mathematics academic achievement. Detailed analysis of variables' direct effects showed that mathematics self-concept had considerable direct influence on motivation to learn mathematics.

    Full Text Available BACKGROUND: Results of studies that address the influence of stress on salivary flow rate and composition are controversial. The aim of this study was to reveal the influence of stress vulnerability and different phases of stress reactivity on the unstimulated and stimulated salivary flow rate. We examined that acute mental stress does not change the salivary flow rate. In addition, we also examined the salivary cortisol and protein level in relation to acute mental stress stimuli. METHODS: Saliva of male subjects was collected for five minutes before, immediately, 10, 30 and 120 min after toothbrushing. Before toothbrushing, the subjects were exposed to acute stress in the form of a 2 min public speech. Salivary flow rate and total protein was measured. The physiological stress marker cortisol was analyzed using enzyme-linked immunosorbent assay. To determine the subjects' psychological stress reaction, the State-Trait-Anxiety Inventory State questionnaire (STAI data were obtained. The subjects were divided into stress subgroup (S1 (psychological reactivity, stress subgroup (S2 (psychological and physiological reactivity and a control group. The area under the curve for salivarycortisol concentration and STAI-State scores were calculated. All data underwent statistical analysis using one-way analysis of variance. RESULTS: Immediately after stress exposure, all participants exhibited a psychological stress reaction. Stress exposure did not change the salivary flow rate. Only 69% of the subjects continued to display a physiological stress reaction 20 minutes after the public talk. There was no significant change in the salivary flow rate during the psychological and the physiological stress reaction phases relative to the baseline. CONCLUSIONS: Acute stress has no impact on the salivary flow rate; however, there may be other responses through salivary proteins that are increased with the acute stress stimuli. Future studies are needed to examine

    Full Text Available To fully understand the pattern of choice, it is important that any explanation of consumer behavior to be accompanied by a complete understanding of the interplay between a consumer’s functional goals and experiential preferences within the decision context. Consumer researchers have increasingly begun to investigate consumer choice based on distinctions that involve the purchase and consumption of goods for pleasure versus for more utilitarian and instrumental purposes. Consumers are often faced with these types of choices between hedonic and utilitarian alternatives that are at least partly driven by emotional desires rather than cold cognitive deliberations. This research approaches factor analysis and multiple linear regression in the context of 150 international respondents and their perception of hedonic and utilitarian motivators on likelihood to buy a tourism package.

    2015-01-01

    The present research elaborates on the regulatory fit hypothesis by investigating a biological stress marker in a motivational fit- and non-fit-situation. Recent stress theories lead to the assumption that the participants' stress level in fit-situations remains constant or rather decreases, whereas under non-fit-conditions an increase of the stress activity is observed. We tested this hypothesis by assessment of salivary α-amylase (sAA), a saliva-based stress marker presumed to reflect noradrenergic activity. The results indicated that participants in a fit-situation show a decrease in sAA, whereas participants in a non-fit-situation demonstrate a contrary effect with an increase in sAA. These findings extend the concept of regulatory fit by illustrating that there are differences in sAA activity depending on whether participants are in a fit-situation. The experience of regulatory fit appears to be associated with a reduction of stress.

    Full Text Available Low malathion concentrations influence metabolism in Chironomus sancticaroli (Diptera, Chironomidae in acute and chronic toxicity tests. Organophosphate compounds are used in agro-systems, and in programs to control pathogen vectors. Because they are continuously applied, organophosphates often reach water sources and may have an impact on aquatic life. The effects of acute and chronic exposure to the organophosphate insecticide malathion on the midge Chironomus sancticaroli are evaluated. To that end, three biochemical biomarkers, acetylcholinesterase (AChE, alpha (EST-α and beta (EST-β esterase were used. Acute bioassays with five concentrations of malathion, and chronic bioassays with two concentrations of malathion were carried out. In the acute exposure test, AChE, EST-α and EST-β activities declined by 66, 40 and 37%, respectively, at 0.251 µg L-1 and more than 80% at 1.37, 1.96 and 2.51 µg L-1. In chronic exposure tests, AChE and EST-α activities declined by 28 and 15% at 0.251 µg L-1. Results of the present study show that low concentrations of malathion can influence larval metabolism, indicating high toxicity for Chironomus sancticaroli and environmental risk associated with the use of organophosphates.

    Major improvements in maternal and neonatal health (MNH) remain elusive in Tanzania. The causes are closely related to the health system and overall human resource policy. Just 35% of the required workforce is actually in place and 43% of available staff consists of lower-level cadres such as auxiliaries. Staff motivation is also a challenge. In rural areas the problems of recruiting and retaining health staff are most pronounced. Yet, it is here that the majority of the population continues to reside. A detailed understanding of the influences on the motivation, performance and job satisfaction of providers at rural, primary level facilities was sought to inform a research project in its early stages. The providers approached were those found to be delivering MNH care on the ground, and thus include auxiliary staff. Much of the previous work on motivation has focused on defined professional groups such as physicians and nurses. While attention has recently broadened to also include mid-level providers, the views of auxiliary health workers have seldom been explored. In-depth interviews were the methodology of choice. An interview guideline was prepared with the involvement of Tanzanian psychologists, sociologists and health professionals to ensure the instrument was rooted in the socio-cultural setting of its application. Interviews were conducted with 25 MNH providers, 8 facility and district managers, and 2 policy-makers. Key sources of encouragement for all the types of respondents included community appreciation, perceived government and development partner support for MNH, and on-the-job learning. Discouragements were overwhelmingly financial in nature, but also included facility understaffing and the resulting workload, malfunction of the promotion system as well as health and safety, and security issues. Low-level cadres were found to be particularly discouraged. Difficulties and weaknesses in the management of rural facilities were revealed. Basic steps

    Both implicit and explicit cognitions play an important role in the development of addictive behavior. This study investigated the influence of a single-session motivational interview (MI) on implicit and explicit alcohol-related cognition and whether this intervention was successful in consequently decreasing alcohol use in at-risk adolescents. Implicit and explicit alcohol-related cognitions were assessed at pretest and one month posttest in 125 Dutch at-risk adolescents ranging in age from 15 to 23 (51 males) with adapted versions of the Implicit Association Test (IAT) and an expectancy questionnaire. Motivation to change, alcohol use and alcohol-related problems were measured with self-report questionnaires, at pretest, at posttest after one month, and at the six-month follow-up. Although the quality of the intervention was rated positively, the results did not yield support for any differential effects of the intervention on drinking behavior or readiness to change at posttest and six-month follow-up. There were indications of changes in implicit and explicit alcohol-related cognitions between pretest and posttest. Our findings raise questions regarding the use of MI in this particular at-risk adolescent population and the mechanisms through which MI is effective. PMID:19290699

    The proportion of stroke patients eligible for intravenous or intra-arterial treatment is still limited because many patients do not seek medical help immediately after stroke onset. The aim of our study was to explore which intrinsic factors and considerations influence help-seeking behaviour of relatively healthy participants, confronted with stroke situations. Semi-structured interviews were conducted with 25 non-stroke participants aged 50 years or older. We presented 5 clinical stroke situations as if experienced by the participants themselves. Recognition and interpretation of symptoms were evaluated and various factors influencing help-seeking behaviour were explored in-depth. We used the thematic synthesis method for data analysis. Five themes influencing help-seeking behaviour in a stroke situation were identified: influence of knowledge, views about seriousness, ideas about illness and health, attitudes towards others and beliefs about the emergency medical system. A correct recognition of stroke symptoms or a correct interpretation of the stroke situations did not automatically result in seeking medical help. Interestingly, similar factors could lead to different types of actions between participants. Many intrinsic, as well as social and environmental factors are of influence on help-seeking behaviour in an acute stroke situation. All these factors seem to play a complex role in help-seeking behaviour with considerable inter-individual variations. Accomplishing more patients eligible for acute stroke treatment, future research should focus on better understanding of all factors at various levels grounded in a theory of help-seeking behaviour.

    Full Text Available Currently, there is a growing demand for physical exercise in programs promoting health; however, the elderly are still under-represented in such programs. This study aims to identify, classify and discuss social, cultural and educational factors relating to the health and quality of life of the elderly, establishing relationships with the motives for which they join and adhere to regular physical exercise programs in public areas. This was a field study employing descriptive quantitative and qualitative methodology and for which 120 participants from two physical exercise programs in Recife were interviewed. The results indicate that the most important motives for participation were as follows: to improve health (84.2%, to improve physical performance (70.8%, to adopt a healthy lifestyle (62.5%, to reduce stress (60.8%, to comply with doctor’s orders (56.7%, to recover from injury (55%, to improve self-image (50.8% and to enhance self-esteem and relax (47.5%. The most important motives for continuing to attend such programs were: to improve posture (75%; to promote a feeling of wellbeing (74.2%; to keep fi t (70.8%; to experience pleasure (66.7%; to become stronger and be motivated by the instructor (62.5%; to experience a feeling of well-being produced by the social environment (60%; and to experience self-realization and receive attention from the instructor (57.5%. For the men (35.1%, the habit of performing physical exercise in their youth had no bearing on their joining such programs. On the basis of these indicators, universities can make a valuable contribution by offering socio-educational health-related projects encouraging the elderly population to avoid a sedentary lifestyle. RESUMO Atualmente, a busca pela prática de exercícios físicos em programas para promoção de saúde vem crescendo; porém a procura pelos idosos é insuficiente.

    Management and supervision of community health workers are factors that are critical to the success of community health worker programmes. Yet few studies have explored the perspectives of supervisors in these programmes. This study explored factors influencing motivations of supervisors in community health worker programmes. We conducted qualitative interviews with 26 programme staff providing supervision to community health workers in eight community-based organizations in marginalized communities in the greater Durban area of South Africa from July 2010 to September 2011. Findings show that all the supervisors had previous experience working in the health or social services sectors and most started out as unpaid community health workers. Most of the participants were poor women from marginalized communities. Supervisors' activities include the management and supply of material resources, mentoring and training of community health workers, record keeping and report writing. Supervisors were motivated by intrinsic factors like making a difference and community appreciation and non-monetary incentives such as promotion to supervisory positions; acquisition of management skills; participation in capacity building and the development of programmes; and support for educational advancement like salary, bonuses and medical benefits. Hygiene factors that serve to prevent dissatisfaction are salaries and financial, medical and educational benefits attached to the supervisory position. Demotivating factors identified are patients' non-adherence to health advice and alienation from decision-making. Dissatisfiers include working in crime-prevalent communities, remuneration for community health workers (CHWs), problems with material and logistical resources, job insecurity, work-related stressors and navigating the interface between CHWs and management. While participants were dissatisfied with their low remuneration, they were not demotivated but continued to be motivated

    Full Text Available The majority of short distance travel in North America is completed by single occupancy vehicles. Substituting walking and bicycling for these trips would reduce energy use and environmental pollution, while improving quality of life. Therefore, understanding influences on non-automotive travel behavior is crucial. Researchers and planners have touted specific factors for encouraging walking and biking, but the body of work remains fragmented. Previous studies have focused on a smaller number of factors and most of them relate to physical design. This study tests the relative importance of a range of factors, both physical and perceptual that could influence one’s choice to walk or bike. The Mt. Pleasant neighborhood in Vancouver, B.C., Canada was chosen as the location for this study as all of the pedestrian-motivating factors identified in a literature review were present. A questionnaire-based survey addressing distance, sidewalks/bike lanes, pedestrian/bicycle traffic signals, buffering from auto traffic, sense of security, cleanliness, opportunities to talk with others, enforcement of traffic laws, concern for the environment, weather, terrain, saving money, opportunities for exercise, and a visually appealing environment as influential factors was administered in person and online yielding 774 responses. All factors were shown to influence the decision to walk or bike, but some proved more significant than others, especially opportunities for exercise.

    This study investigates the influence of habitual caffeine intake on aerobic exercise-performance responses to acute caffeine supplementation. A double-blind, crossover, counterbalanced study was performed. Forty male endurance-trained cyclists were allocated into tertiles, according to their daily caffeine intake: low (58 ± 29 mg/d), moderate (143 ± 25 mg/d), and high (351 ± 139 mg/d) consumers. Participants completed three trials in which they performed simulated cycling time trials (TTs) in the fastest time possible following ingestion of the following: caffeine (CAF: 6 mg/kg body mass), placebo (PLA), and no supplement (CON). A mixed-model analysis revealed that TT performance was significantly improved in CAF compared with PLA and CON (29.92 ± 2.18 vs. 30.81 ± 2.67 and 31.14 ± 2.71 min, respectively; P = 0.0002). Analysis of covariance revealed no influence of habitual caffeine intake as a covariate on exercise performance ( P = 0.47). TT performance was not significantly different among tertiles ( P = 0.75). No correlation was observed between habitual caffeine intake and absolute changes (CAF - CON) in TT performance with caffeine ( P = 0.524). Individual analysis showed that eight, seven, and five individuals improved above the variation of the test in CAF in the low, moderate, and high tertiles, respectively. A Fisher's exact test did not show any significant differences in the number of individuals who improved in CAF among the tertiles ( P > 0.05). Blood lactate and ratings of perceived exertion were not different between trials and tertiles ( P > 0.05). Performance effects of acute caffeine supplementation during an ~30-min cycling TT performance were not influenced by the level of habitual caffeine consumption. NEW & NOTEWORTHY There has been a long-standing paradigm that habitual caffeine intake may influence the ergogenicity of caffeine supplementation. Low, moderate, and high caffeine consumers showed similar absolute and

    Full Text Available Zinc supplementation is recommended in all acute diarrheas in children from developing countries. We aimed to assess whether zinc supplementation would be equally effective against all the common organisms associated with acute diarrheas. We used data on 801 children with acute diarrhea recruited in a randomized, double blind controlled trial (ISRCTN85071383 of zinc and copper supplementation. Using prespecified subgroup analyses, multidimensionality reduction analyses, tests of heterogeneity, and stepwise logistic regression for tests of interactions, we found that the influence of zinc on the risk of diarrhea for more than 3 days depended on the isolated organism—beneficial in Klebsiella, neutral in Esherichia coli and parasitic infections, and detrimental in rotavirus coinfections. Although we found similar results for the outcome of high stool volume, the results did not reach statistical significance. Our findings suggest that the current strategy of zinc supplementation in all cases of acute diarrheas in children may need appropriate fine tuning to optimize the therapeutic benefit based on the causative organism, but further studies need to confirm and extend our findings.

    Patients with diabetes are at increased risk of experiencing myocardial infarction. The influence of the prevailing plasma glucose level on infarction and mortality after acute ischaemia is however unknown. The aim was to study the effect of the acute plasma glucose level on the myocardial infarction size in a closed-chest pig model. 38 non-diabetic pigs were randomised to hypoglycaemic (1.8-2.2 mmol/l; n = 15), normoglycaemic (5-7 mmol/l; n = 12) or hyperglycaemic glucose clamping (22-23 mmol/l; n = 11). After 30 min within glucose target myocardial infarction was induced for 30 min followed by reperfusion for 120 min. Hereafter the heart was double-stained to delineate infarction from viable tissue within the area at risk. Mean infarction size was 201 ± 35 mm(2) (mean ± SEM) in the hypoglycaemic group, 154 ± 40 mm(2) in the normoglycaemic group and 134 ± 40 mm(2) in the hyperglycaemic group, with no differences in infarction size, infarct/area at risk ratio or troponin T levels between the groups. There was no difference in incidence of ventricular fibrillation or mortality between the groups. No statistically significant associations were observed between the acute glycaemic level and measures of myocardial infarction, rates of ventricular fibrillation and subsequent premature death in the setting of acute ischaemia and reperfusion.

    The first objective of this study was to adapt and test the psychometric properties of the Social Achievement Goal Scale (Ryan & Shim, 2006) in Spanish adolescent students. The second objective sought to analyse the influence of social goals, normative adjustment and self-perception of social efficacy on social adjustment among peers. A total of 492 adolescents (54.1% females) attending secondary school (12-17 years; M = 13.8, SD = 1.16) participated in the study. Confirmatory factor analysis and structural equation modelling were performed. The validation confirmed the three-factor structure of the original scale: social development goals, social demonstration-approach goals and social demonstration-avoidance goals. The structural equation model indicated that social development goals and normative adjustment have a direct bearing on social adjustment, whereas the social demonstration-approach goals (popularity) and self-perception of social efficacy with peers and teachers exert an indirect influence. The Spanish version of the Social Achievement Goal Scale (Ryan & Shim, 2006) yielded optimal psychometric properties. Having a positive motivational pattern, engaging in norm-adjusted behaviours and perceiving social efficacy with peers is essential to improving the quality of interpersonal relationships.

    This study examines the role that motivational values play in the experience of discrimination in young immigrants in Spain and how this role is mediated by parental values. Participants in the study were 193 dyads of pre-adolescent to young adult first and second generation immigrants and one of their parents. All participants were either of Moroccan or Romanian ascent, the two largest immigrant groups in Spain. The proposed SEM model had an adequate fit, χ2(2, N = 193) = 2.272, p = .321, RMSEA = .027, CFI = .999, NFI = .994, and yielded a large R 2, both for the Moroccan group (R 2 = .79, p immigrants high in openness to change are likely to pursue contact with the host culture more intensely, and thus increase the probability of interactions involving discrimination. Additionally, parental values and their own experience of discrimination influences their children, making them more vulnerable to discrimination stress and more likely to perceive discrimination. While most research is focused on external or environmental variables, this study highlights the importance of value orientations and parental influences in immigrants' experience of discrimination.

    The clinical profile with regard to sex and the influences on outcomes in patients who have been hospitalized for acute pericarditis is largely uncharacterized. We studied all patients aged ≥16 years admitted to the hospital because of acute pericarditis (postpericardiotomy and myocardial infarction associated pericarditis were excluded). Data were collected from a Finnish national registry that included data on all cardiovascular admissions (670 409) during 9.5 years in 29 hospitals nationwide. During the study period, there were 1361 admissions for acute pericarditis. Pericarditis patients were more likely to be male (64.9% of patients) than female (35.1%), with an age-adjusted likelihood ratio of 1.85 (95% confidence interval [CI], 1.65-2.06; Ppericarditis was 3.32 per 100 000 person-years. Men 16 to 65 years of age were at higher risk for pericarditis (relative risk, 2.02; 95% CI, 1.81-2.26; Ppericarditis caused 0.20% (95% CI, 0.19%-0.22%) of all cardiovascular admissions. The proportion of pericarditis-caused admissions declined by an estimated 51% per 10-year increase in age. The in-hospital mortality rate for acute pericarditis was 1.1% (95% CI, 0.6%-1.8%). Mortality increased with age (hazard ratio, 3.26; 95% CI, 1.78-5.95 per 10-year increase in age; P=0.0001) and severe coinfection (pneumonia or septicemia; hazard ratio, 13.46; 95% CI, 2.26-80.01; Ppericarditis are more commonly male. Increasing age and severe coinfection are associated with greater in-hospital mortality in hospitalized acute pericarditis patients. © 2014 American Heart Association, Inc.

    There are few studies analysing the influence of personal traits and motivation factors on Facebook usage and Facebook addictive tendency as seen in university students. In this study, 225 Taiwanese university students completed a questionnaire to determine their online psychological privacy scale, Facebook usage motivation scale, Facebook usage scale and Facebook addictive tendency scale, in order to evaluate the items that can be conceptualized as the effect of university students' online psychological privacy personal trait and motive factors, and Facebook usage motivation with respect to Facebook usage and Facebook addictive tendency. The study found that a desire for more online psychological privacy correlates with a stronger motivation to use Facebook and more Facebook usage behaviour among university students who may become high-risk groups for Facebook addictive tendency. The study found that a desire for or an acceptance of a lower online psychological privacy correlates with a stronger motivation to use Facebook among university students who may have more Facebook usage behaviour. This study can help understand university students' Facebook usage and Facebook addictive tendency and provide feature indicators for those who may become high-risk groups for Facebook addictive tendency. Finally, this study conducts discussion and proposes relevant suggestions for future study. Copyright © 2014 John Wiley & Sons, Ltd.

    There is a shortage of doctors working in rural areas all over the world, especially in low-income and middle-income countries. The choice to practise medicine in a rural area is influenced by many factors. Motivation developed as a medical student is one key determinant of this choice. This study explores influences on medical students' motivation to practise in rural areas of low-income and middle-income countries following graduation. A systematic review was conducted to identify influences on medical students' motivation to work in rural areas in low-income and middle-income countries. Papers reporting influences on motivation were included, and content analysis was conducted to select the articles. Articles not published in English were excluded from this review. A rural background (ie, being brought up in a rural area), training in rural areas with a community-based curriculum, early exposure to the community during medical training and rural location of medical school motivate medical students to work in rural areas. Perceived lack of infrastructure, high workload, poor hospital management and isolation are among the health facility factors that demotivate medical students for medical practice in rural areas. Medical school selection criteria focusing on a rural background factor and medical education curriculum focusing on rural area are more relevant factors in low-income and middle-income countries. The factors identified in this review may assist the planners, medical educators and policymakers in low-income and middle-income countries in designing relevant interventions to positively influence rural choices where the shortage of rural physicians is an ongoing and increasing concern.

    201 Tl stress myocardial scintigraphy was performed in convalescent patients with acute myocardial infarction, to evaluate the influence of stenosis and collateral circulation of coronary artery in acute phase, on myocardial salvage in chronic phase. In 14 cases of unsuccessful coronary revascularization (complete occlusion), a complete defect of thallium imaging in chronic phase was seen in only one case of four cases with good collateral circulation, while eight of 10 cases with poor collateral circulation. In 16 cases with collateral circulation, six cases showed a complete defect, although the target vessel had improved to less than 75% of stenosis. However, in cases of good collateral circulation, no case showed a complete defect when the target vessel had improved to less than 75% of stenosis. The myocardial salvage is quite possible (p<0.05), when the coronary angiography in acute phase showed the forward flow (99% or 90% of stenosis) before coronary revascularization and/or good collateral circulation (Rentrop 2deg or 3deg).

    Kearney, D

    2012-02-03

    PURPOSE: This study analyzed whether prehospital or in-hospital delay was the more significant influence on perforation rates for acute appendicitis and whether any clinical feature designated patients requiring higher surgical priority. METHODS: A retrospective analysis was conducted over one year at a tertiary referral hospital without a dedicated emergency surgical theater. Admission notes, theater logbook, and the Hospital Inpatient Enquiry system were reviewed to identify the characteristics and clinical course of patients aged greater than 16 years who were operated upon for histologically confirmed acute appendicitis. RESULTS: One hundred and fifteen patients were studied. The overall perforation rate was 17 percent. The mean duration of symptoms prior to hospital presentation was 38.1 hours with the mean in-hospital waiting time prior to operation being 23.4 hours. Although body temperature on presentation was significantly greater in patients found to have perforated appendicitis (P < 0.05), only patient heart rate at presentation and overall duration of symptoms, but not in-hospital waiting time, independently predicted perforation by stepwise linear regression modeling. CONCLUSION: In-hospital delay was not an independent predictor of perforation in adults with acute appendicitis although delays may contribute if patients are left to wait unduly. Tachycardia at presentation may be a quantifiable feature of those more likely to have perforation and who should be given higher surgical priority.

    Objective: Acute poisonings with caustic substances can cause severe chemical injuries to the upper gastrointestinal tract, which can be localized from the mouth to the small intestines. They are seen very often among young people in their most productive years. The aim of this study is to examine the influence of patient’s age on the mortality rate and survival of patients with acute caustic poisonings, and also to analyze their correlation. Material and Methods: We studied medical records from 415 patients, aged between 14 and 90 years, who were hospitalized and treated at the University Clinic for toxicology and urgent internal medicine, Skopje, Republic of Macedonia, in the period between 2007 and 2011. Results: In the survey we included 415 patients with acute corrosive poisonings, from which 295 (71.08%) were females and 120 (28. 92%) were males. 388 (93.49%) from the total number of patients ingested the corrosive agent with suicidal attempt and 27 (6.5%) ingested it accidentally. Conclusion: Unregulated production, import, packing and labeling of various caustic agents, due to inappropriate legislative, made them one of the most often abused substances in everyday life, especially in developing countries where the number of caustic poisonings rises.

    Research has shown that outdoor educational interventions can lead to students' increased self-regulated motivational behavior. In this study, we searched into the satisfaction of basic psychological needs (BPN), i.e., autonomy support, the learners' experience of competence, and relatedness, both within the peer group and with their teachers, through outdoor learning. From 2014 to 2016, n = 281 students attended “research weeks” at a Student Science Lab in the Alpine National Park Berchtesgaden (Germany). The program is a curriculum-based one-week residential course, centered on a 2-day research expedition. Both before and after the course, students completed a composite questionnaire addressing BPN-satisfaction and overall motivational behavior in relation to the Self-Determination Index (SDI). At the latter time-point, students also reported on their experiences during the intervention. Questionnaire data was analyzed using a set of Bayesian General Linear Models with random effects. Those quantitative measures have been complemented by and contextualized with a set of qualitative survey methods. The results showed that the basic psychological needs influence the motivational behavior in both contexts equally, however on different scale levels. The basic needs satisfaction in the outdoor context is decisively higher than indoors. Moreover, the increment of competence-experience from the school context to the hands-on outdoor program appears to have the biggest impact to students' increased intrinsic motivation during the intervention. Increased autonomy support, student-teacher relations, and student-student relations have much less or no influence on the overall difference of motivational behavior. Gender does not influence the results. The contextualization partly supports those results and provide further explanation for the students' increased self-regulation in the outdoors.

    Full Text Available Background. The synthetic opioid analgesic fentanyl is widely used for prophylaxis and therapy of traumatic shock associated with massive bleeding. Its side effects – skeletal muscle rigidity and respiratory center depression – are especially pronounced with repeated administration. It is rational to apply fentanyl in diminished doses in combination with non-opioid analgesics in order to reduce respiratory disturbances risk.Aim. The aim of the work is to justify the influence of opioid analgesic fentanyl and α2 -adrenomimetic dexmedetomidine combination on external respiratory functions in acute hemorrhage model.Materials and methods. Acute loss of 35–40% of circulating blood volume was modeled in experiments on 75 white mongrel male rats. The external respiratory functions (respiratory rate, respiratory volume, breath volume per minute were estimated in animals of 5 groups: 1 – rats without analgesic help (controls; 2–3 – rats receiving a single fentanyl intramuscular injection (ED99 98,96 mcg/kg or fentanyl together with dexme detomidine (ED99 of combination 67,94 mcg/kg 15 min after acute blood loss; 4–5 – rats receiving the same drugs 15 min, 30, 45 and 60 min later.Results. In experimental acute loss of 35–40% of circulating blood volume, 15 min later a secondary acute respiratory failure developed with a drop of respiratory rate, respiratory volume and volume of breath per minute by 30%, 21 and 47% (p < 0,05. The external respiratory functions recoverеd after 4 h mainly due to the increase of respiratory volume. A single intramuscular injection of fentanyl caused respiratory depression 15 min after experimental blood loss which resulted in the decrease of breath volume per minute to 30–61% (p < 0,05 for 90 min. Four intramuscular injections of fentanyl 15 min, 30, 45 and 60 min after hemorrhage caused a severe respiratory dysfunction, accompanied by apnea periods and Biot’s respiration. Respiratory rate was reduced

  1. An Integrated Behavioural Model towards Evaluating and Influencing Energy Behaviour—The Role of Motivation in Behaviour Demand Response

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available The change in the actual use of buildings by its occupants is receiving more and more attention. Over the lifecycle of a building the occupants and therefore the demands towards the buildings often change a lot. To match these altering conditions, particularly in the context of the demand for energy efficiency, purely technical approaches usually cannot solve the problem on their own or are not financially viable. It is therefore essential to take the behaviour of the end user into account and ask the fundamental question: “How is it possible to influence people’s behaviour towards a more pro-environmental outcome, and also in the long-term?” To approach this question we will present a model-driven approach for dynamically involving building occupants into the energy optimisation process. To do so we will further develop an integrated behavioural model based on established behavioural theories, having a closer look how motivational variables can be integrated into the process. This should lead to novel approaches for behaviour demand response, enabling additional demand shifting and shedding through targeted real-time engagement with energy prosumers.

  2. Managing motivational conflict: how self-esteem and executive resources influence self-regulatory responses to risk.

    This article explores how self-esteem and executive resources interact to determine responses to motivational conflict. One correlational and 3 experimental studies investigated the hypothesis that high and low self-esteem people undertake different self-regulatory strategies in "risky" situations that afford opportunity to pursue competing goals and that carrying out these strategies requires executive resources. When such resources are available, high self-esteem people respond to risk by prioritizing and pursuing approach goals, whereas low self-esteem people prioritize avoidance goals. However, self-esteem does not influence responses to risk when executive resources are impaired. In these studies, risk was operationalized by exposing participants to a relationship threat (Studies 1 and 2), by using participants' self-reported marital conflict (Study 3), and by threatening academic competence (Study 4). Executive resources were operationalized as cognitive load (Studies 1 and 2), working memory capacity (Study 3), and resource depletion (Study 4). When executive resources were ample, high self-esteem people responded to interpersonal risk by making more positive relationship evaluations (Studies 1, 2, and 3) and making more risky social comparisons following a personal failure (Study 4) than did low self-esteem people. Self-esteem did not predict participants' responses when executive resources were impaired or when risk was absent. The regulatory function of self-esteem may be more resource-dependent than has been previously theorized.

    Antimicrobial use in acute care is widely reported to be suboptimal. Inappropriate use of antimicrobials is a major contributing factor to the emergence of multidrug resistance and health care-associated infection. Addressing prescribing behavior is a key component of antimicrobial stewardship. We performed a novel systematic review of both qualitative and quantitative literature on antimicrobial prescribing behavior in acute care. We assessed the extent to which behavioral sciences and social marketing were used and whether this could be related to the effectiveness of reported outcomes. MEDLINE, Excerpta Medica Database (EMBASE), Applied Social Sciences Index and Abstracts (ASSIA), Business Source Complete, The Cochrane Library, PsychInfo, Database of Abstracts of Reviews of Effectiveness (DARE) and Health Management Information Consortium (HMIC) were searched for studies undertaken during the period January 1999-April 2011 and published in English. Five qualitative and 5 quantitative studies met the quality criteria. Qualitative studies highlight the predominant influence of social norms, attitudes, and beliefs on antimicrobial prescribing behavior. Quantitative studies reporting interventions to optimize antimicrobial prescribing behavior do not use theoretical science or primary research to inform the design and choice of the interventions deployed. Despite qualitative evidence demonstrating the impact of behavioral determinants and social norms on prescribing, these influences are not given due consideration in the design and evaluation of interventions. To ensure a better understanding of prescribing behaviors and to improve the quality of interventions and research in this area, the incorporation and application of behavioral sciences supported by appropriate multidisciplinary collaboration is recommended.

    Understanding what types of social norms are more or less influential and how they operate with respect to other psychological variables can provide valuable insights into the design of effective social norm campaigns. To this end, this study explores the roles of two types of social norms (injunctive norms and descriptive norms) and two types of drinking motives (social motives and conformity motives) in collegiate drinking behavior in South Korea. A survey of Korean college students (N = 569) revealed significant positive effects of injunctive norms, descriptive norms, and social motives on students' drinking frequency and quantity. Conformity motives were positively related to the frequency of drinking but negatively related to the quantity of drinking. Furthermore, the results revealed significant effects of the interactions between descriptive norms and social motives (on both the frequency and quantity of alcohol consumption), such that the positive effect of descriptive norms was more pronounced among individuals with stronger social motives. A similar pattern was observed in the interaction between injunctive norms and conformity motives (on frequency). Theoretical and practical implications of the findings for social norm campaigns seeking to curb drinking among college students are discussed.

    This study tested a recent theoretical development in stress research to see whether group membership influenced cardiovascular reactions following exposure to acute stress. Participants (N = 104) were exposed to a message in which a maths test was described as stressful or challenging by an ingroup member (a student) or outgroup member (a stress disorder sufferer). Systolic blood pressure and diastolic blood pressure(DBP) and heart rate (HR) were monitored throughout a standard reactivity study. As expected, a significant interaction was found; relative to those who were told that the task was challenging, ingroup members reported more stress and had higher DBP and HR reactivity when told by an ingroup member that the maths task was stressful; task information did not have the same effect for outgroup members. These results indicate that informational support is not constant but varies as a function of group membership. Finally, this recent development in stress research may prove useful for those interested in investigating the interactions between social, psychological and physiological processes underlying health disparities. What is already known on this subject? Stress is a common risk factor for hypertension and coronary heart disease. Social support has been found to reduce cardiovascular reactions to acute psychological stress. The influence of social support on stress varies as a consequence of social identity. What does this study add? The social group that one belongs to influences how one appraises and responds to stress. Social identity provides a useful framework for understanding how social processes are associated with health disparities. © 2013 The British Psychological Society.

    Individuals diagnosed with acute HIV infection (AHI) are highly infectious and require immediate HIV prevention efforts to minimize their likelihood of transmitting HIV to others. We sought to explore the relevance of Motivational Interviewing (MI), an evidence-based counseling method, for Malawians with AHI. We designed a MI-based intervention called "Uphungu Wanga" to support risk reduction efforts immediately after AHI diagnosis. It was adapted from Options and SafeTalk interventions, and refined through formative research and input from Malawian team members and training participants. We conducted qualitative interviews with counselors and participants to explore the relevance of MI in this context. Intervention adaptation required careful consideration of Malawian cultural context and the needs of people with AHI. Uphungu Wanga's content was relevant and key MI techniques of topic selection and goal setting were viewed positively by counselors and participants. However, rating levels of importance and confidence did not appear to help participants to explore behavior change as intended. Uphungu Wanga may have provided some added benefits beyond "brief education" standard of care counseling for Malawians with AHI. MI techniques of topic selection and goal setting may enhance prevention education and counseling for Malawians with AHI. Copyright © 2018 Elsevier B.V. All rights reserved.

    A major reason for poor survival of childhood acute lymphoblastic leukemia in developing countries is treatment refusal or abandonment. This can be associated with parental socioeconomic status and attitudes of health care providers. Our study examined the influence of 2 socioeconomic status determinants, parental income and education, on treatment in an Indonesian academic hospital. Medical charts of 164 patients who received a diagnosis of acute lymphoblastic leukemia between 1997 and 2002 were abstracted retrospectively. Data on treatment results and parental financial and educational background were collected. Open interviews were conducted with parents and health care providers. Of all patients, 35% refused or abandoned treatment, 23% experienced treatment-related death, 22% had progressive or relapsed leukemia, and 20% had an overall event-free survival. Treatment results differed significantly between patients with different socioeconomic status; 47% of poor and 2% of prosperous patients refused or abandoned treatment. Although poor and prosperous patients used the same protocol, the provided treatment differed. Poor patients received less individualized attention from oncologists and less structured parental education. Strong social hierarchical structures hindered communication with doctors, resulting in a lack of parental understanding of the necessity to continue treatment. Most poor patients could not afford treatment. Access to donated chemotherapy also was inadequate. Treatment refusal or abandonment frequently resulted. There was no follow-up system to detect and contact dropouts. Health care providers were not fully aware that their own attitude and communication skills were important for ensuring compliance of patients and parents. Children's survival of acute lymphoblastic leukemia in developing countries could improve if problems that are associated with parental financial and educational background and medical teams' attitudes to treatment and

    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.

    This study addressed the factors that nursing staff perceived as creating job satisfaction in their working environment in addition to addressing the ethical dilemmas that staff experienced within an acute psychiatric care setting. It also addressed how clinical supervision contributed to job satisfaction among staff as well as the differences between staff who attended and staff who did not attend to clinical supervision. Data were analyzed using descriptive statistics. Overall, the results of this study showed that the factors influencing nurses are related to areas of dissatisfaction, for example, stress and experiences with shortcomings. Factors that contribute to job satisfaction or dissatisfaction were found to be related to the nurses' value systems. The ethical dilemmas that were specifically addressed involved how to care for patients and handle work in relation to patients' autonomy, how to approach the patient, how to provide care against the will of the patient, and what action was ethically right for each particular patient.

  15. Differentiating Motivational from Affective Influence of Performance-contingent Reward on Cognitive Control: The Wanting Component Enhances Both Proactive and Reactive Control.

    Positive affect strongly modulates goal-directed behaviors and cognitive control mechanisms. It often results from the presence of a pleasant stimulus in the environment, whether that stimulus appears unpredictably or as a consequence of a particular behavior. The influence of positive affect linked to a random pleasant stimulus differs from the influence of positive affect resulting from performance-contingent pleasant stimuli. However, the mechanisms by which the performance contingency of pleasant stimuli modulates the influence of positive affect on cognitive control mechanisms have not been elucidated. Here, we tested the hypothesis that these differentiated effects are the consequence of the activation of the motivational "wanting" component specifically under performance contingency conditions. To that end, we directly compared the effects on cognitive control of pleasant stimuli (a monetary reward) attributed in a performance contingent manner, and of random pleasant stimuli (positive picture) not related to performance, during an AX-CPT task. Both proactive and reactive modes of control were increased specifically by performance contingency, as reflected by faster reaction times and larger amplitude of the CNV and P3a components. Our findings advance our understanding of the respective effects of affect and motivation, which is of special interest regarding alterations of emotion-motivation interaction found in several psychopathological disorders.

    Despite rural health services being situated and integrated within communities in which people work and live, the complex interaction of the social environment on health worker motivation and performance in Low Middle Income Countries has been neglected in research. In this article we investigate how social factors impact on health worker motivation and performance in rural health services in Papua New Guinea (PNG). Face-to-face in-depth interviews were conducted with 33 health workers from three provinces (Central, Madang, and Milne Bay) in PNG between August and November 2009. They included health extension officers, community health workers and nursing officers, some of whom were in charge of the health centres. The health centres were a selection across church based, government and private enterprise health facilities. Qualitative analysis identified the key social factors impacting on health worker motivation and performance to be the local community context, gender roles and family related issues, safety and security and health beliefs and attitudes of patients and community members. Our study identified the importance of strong supportive communities on health worker motivation.

    Full Text Available Motivation of teachers for professional-pedagogical activity and levels of forming of their pedagogical skills were determined based on the results of self evaluation and evaluation that was performed by the students. Evaluation of teachers' pedagogical skills and self evaluation were compared to dominating motivation for professional activity of teachers. 42 teachers and 78 students took part in this experiment. To determine proffessional-pedagogical activity motivation the tool of K. Zamfir in modification by A. Rean was used. To determine self evaluation of pedagogical skills "Scale of self evaluation of pedagogical activity" and tool of B. Zelentsov "Students about a teacher" were used. It was shown that it is characteristic for teachers to over estimate their pedagogical skills in comparison to the evaluation made by students: high level of forming of pedagogical skills comprise 40,48 % of respondents, while according to the students evaluation this figure is almost twice lower and comprises - 21,43%; average level evaluation, shows only 14,28 %, when students evaluate that 35,71% of teachers have average level of pedagogical skills forming. It was declared that teachers with the most determined internal motives are more objective in their self evaluation. It was proven that teachers whose pedagogical skills are on high level and who are evaluated by the students on the same level the are lead by domination of internal motivation.

    2009-04-01

    This study assessed motives for social network site (SNS) use, group belonging, collective self-esteem, and gender effects among older adolescents. Communication with peer group members was the most important motivation for SNS use. Participants high in positive collective self-esteem were strongly motivated to communicate with peer group via SNS. Females were more likely to report high positive collective self-esteem, greater overall use, and SNS use to communicate with peers. Females also posted higher means for group-in-self, passing time, and entertainment. Negative collective self-esteem correlated with social compensation, suggesting that those who felt negatively about their social group used SNS as an alternative to communicating with other group members. Males were more likely than females to report negative collective self-esteem and SNS use for social compensation and social identity gratifications.

    Our aim was to investigate the influence of thymic polypeptides on pain sensitivity and to analyze a possible role of the opioid system in the implementation of the analgesia caused by immobilization stress. The study was performed on male Wistar rats at the Moscow state University named after M. V. Lomonosov. We studied effects of thymus peptides: thymuline (0.15 mg/kg), fraction 5 thymosin (0.25 microgram/kg) and cattle thymus extracted product (CTEP) (0.5 mg/kg) on pain sensitivity in rats using test "tail flick" without stress, with acute (3 h) and sub acute (12 h) immobilization stress. The comparison groups were animals treated with saline and spleen polypeptides. It is shown that preparations of thymus increase the threshold of pain sensitivity in the intact animals. Immobilization stress duration 3 and 12 h in thymus peptides treated rats caused a less pronounced increase in pain threshold than in the control groups (immobilization stress 3 h: CTEP--p = 0.025, thymuline--p = 0.022, fraction 5 thymosin--p = 0.033; immobilization stress 12 h: CTEP--p = 0.034, thymuline--p = 0.027, fraction 5 thymosin--p = 0.036). The opioid receptor blocker naloxone (1 mg/kg) did not completely block the stress-induced analgesia, indicating the presence of both opioid and non -opioid components in this state. In thymus peptides treated rats, opioid component was less pronounced than in the control groups (CTEP--p = 0.031, thymuline--p = 0.026, fraction 5 thymosin--p = 0.029). Pre-activation of the opioid system by the thymus polypeptides leads to an increase in the share of non-opioid component of the stress-induced analgesia and prevents the depletion of the opioid system in immobilization stress.

    Full Text Available This study evaluated the acute effect of ischemic preconditioning (IPC on a high-intensity intermittent exercise performance and physiological indicators in amateur soccer players. Thirteen players (21.5 ± 2 yrs attended three trials separated by 3–5 days in a counterbalanced randomized cross-over design: IPC (4 × 5-min occlusion 220 mmHg/reperfusion 0 mmHg in each thigh; SHAM (similar to the IPC protocol but “occlusion” at 20 mmHg and control (seated during the same time of IPC. After 6-min of each trial (IPC, SHAM or control, the players performed the YoYo Intermittent Endurance Test level 2 (YoYoIE2. The distance covered in the YoYoIE2 (IPC 867 ± 205 m; SHAM 873 ± 212 m; control 921 ± 206 m was not different among trials (p = 0.10, furthermore, lactate concentration and rate of perceived exertion did not differ (P > 0.05 among protocols. There were also no significant differences in either mean heart rate (HR or peak HR (p > 0.05 for both IPC and SHAM compared to control. Therefore, we conclude that acute IPC does not influence high-intensity intermittent exercise performance in amateur soccer players and that rate of perceived exertion, heart rate and lactate do not differ between the intervention IPC, SHAM and control.

    To investigate the influence of Montelukast (MK) in acute renal failure (ARF) experimentally induced by cisplatin (CIS). The experiment was carried out in male Wistar rats (280-320g), divided into 4 groups of 12 animals each, treated as follows: Group I (Control); Group II (CIS): CIS, 5 mg/kbw, single dose, i.p.; Group III (CISMK): CIS, 5 mg/kbw, single dose, i.p and MK 2 mg/kbw, p.o., 10 days; Group IV (MK): MK 2 mg/kbw, p.o., 10 days. Blood and urine (24 h) samples were taken before the start of experiment (Io) and at 3, 7, 10 and 14 days after CIS administration. The following were determined: urea, creatinine, Ca, Mg serum levels and creatinine, proteins, Ca and Mg urinary levels. For histological evaluation, 3 rats of each group were sacrificed at 3, 7, 10 and 14 days. The severity of histopathological changes was evaluated using scores on a 1-4 point scale. Both in CIS and CISMK group, serum levels of urea and creatinine and urinary protein levels were significantly higher compared with Io values and control group at 3 and 7 days, (p < 0.01 and p < 0.05, respectively). Urinary creatinine levels were significantly decreased at 3 and 7 days, (p < 0.01) and (p < 0.05) in CIS and CISMK group compared to Io and control group. The degree of severity of histopathological changes was similar in CIS and CISMK group. The obtained results showed that MK at a dose of 2 mg/kbw had no protective effect in CIS-induced experimental acute renal failure.

    Understanding motivators for exercise participation in post-menopausal women may impact retention to exercise programmes and inform intervention trial designs. The purpose of this investigation was to assess self-reported motivational factors influencing adherence and retention to a 24-week progressive resistance training programme. Post-menopausal females (n = 34) were passively recruited to undertake a 24-week progressive resistance training protocol, in small-group sessions, on three non-consecutive days of the week. Attendance was recorded by the researcher. Qualitative reports were sourced from the sample for four phases of the study: pre-study (prior to week 1), recruitment (week 1), during study (weeks 2 - 24), and post-intervention (beyond week 24). Responses were categorised according to ten descriptors: specific health index improvement, education, flexibility of time, social contact, conscience (loyalty to the researcher), wellness, weight management, organisation parameters (pertaining to the study programme) and enjoyment of the exercises. Of the initial sample, 76.5% (n = 26) met the specified ≥80% attendance criterion. The primary findings were that motivation to volunteer for the study was driven by a perceived need for a structured exercise programme (50% of respondents). A commitment to the researcher was the primary motivator for continued adherence to the study for 50% of participants. Social contact with other participants was cited by 60% of the sample as the primary reason for adherence for the full duration of 24 weeks. A desire to maintain the "wellness" derived from the programme was cited by 60% as a reason for continuing an exercise routine post-study. This study identified that routine and supervision initially attract women to exercise programmes, while social cohesion of the group setting contributes to retention over time. Understanding the changing nature of motivating factors may contribute to better overall adherence

    Pokémon GO is the most played augmented reality game in history. With more than 44 million players at the peak of its popularity, the game has sparked interest on its effects on the young population's health. This pilot study examined motivations to start playing Pokémon GO among a sample of US college students, and how motivations were associated with perceived outcomes of the playing experience and physical activity derived while playing. In November 2016, we asked a sample of 47 US college students (all Pokémon GO players) to complete online surveys and install an ecological momentary assessment (EMA) tool and step counter on their smartphones. The EMA tool prompted a set of questions on playing behavior and physical activity, 3 times per day (12:00 PM, 7:00 PM, and 10:00 PM), for 7 days. We used a factorial analysis to identify 3 distinctive groups of players based on their motivations to start playing Pokémon GO. We tested differences across motivation groups related to 5 unique outcomes using 1-way analysis of variance. We extracted 3 interpretable factors from the clustering of motivations to start playing Pokémon GO: Pokémon and video game fans (n=26, 55% of the sample), physical activity seekers (n=8, 17%), and curious & social (n=13, 28%). The clusters differed significantly on the enjoyment of different aspects of the game, particularly battling, discovering new places, and meeting new people, as well as differences in agreement that playing improved mood and made them more social. Days when playing Pokémon GO were associated with higher number of steps reported at the end of the day, especially among physical activity seekers, but also for Pokémon and video game fans. All groups perceived traffic as a major threat to playing. Days during which Pokémon GO was played were positively associated with a set of beneficial health behaviors, including higher physical activity levels, more socialization, and better mood. Results, however, depended on

    To determine the frequency of manual and oral apraxia in acute stroke and to examine the influence of these symptoms on functional outcome. Seven hundred seventy six unselected, acute stroke patients who were admitted within seven days of stroke onset with unimpaired consciousness were included. If possible, the patients were assessed for manual and oral apraxia on acute admission. Neurologic stroke severity including aphasia was assessed with the Scandinavian Stroke Scale, and activities of daily living function was assessed with the Barthel Index. All patients completed their rehabilitation in the same large stroke unit. Six hundred eighteen patients could cooperate with the apraxia assessments. Manual apraxia was found in 7% of subjects (10% in left and 4% in right hemispheric stroke; chi2 = 9.0; P = 0.003). Oral apraxia was found in 6% (9% in left and 4% in right hemispheric stroke; chi2 = 5.4; P = 0.02). Both manual and oral apraxia were related to increasing stroke severity, and manual, but not oral, apraxia was associated with increasing age. There was no gender difference in frequency of apraxia. Patients with either type of apraxia had temporal lobe involvement more often than patients without. When analyzed with multiple linear and logistic regression analyses, neither manual nor oral apraxia had any independent influence on functional outcome. Apraxia is significantly less frequent in unselected patients with acute stroke than has previously been assumed and has no independent negative influence on functional outcome.

    Community drug distributors or neglected tropical disease (NTD) volunteers have played a crucial role in ensuring the success of mass drug administration (MDA) programs using preventive chemotherapy (PC) for lymphatic filariasis, onchocerciasis, schistosomiasis, trachoma and soil transmitted helminths. In recent years however, a noticeable decline in motivation of some of these volunteers has been perceived, potentially negatively impacting the success of these programs. Potential hypotheses for this change in motivation include the long duration of many MDA programs, the change in sociocultural environments as well as the changes to the programs over time. This literature review identifies factors that affect NTD volunteer performance and motivation, which may be used to influence and improve future programming. A systematic search was conducted to identify studies published between January 1995 and September 2016 that investigate factors pertaining to volunteer motivation and performance in NTD drug distribution programs. Searches from several databases and grey literature yielded 400 records, of which 28 articles from 10 countries met the inclusion criteria. Quality assessment of studies was performed using the Critical Appraisal Skills Programme(CASP) checklist. Data pertaining to motivation, performance, retention and satisfaction was extracted and examined for themes. Recurring themes in the literature included monetary and material incentives, intrinsic motivation, gender, cost to participate, and health systems and community support. Of these, community support and the health system were found to be particularly impactful. Very few studies were found to explicitly look at novel incentives for volunteers and very few studies have considered the out of pocket and opportunity costs that NTD volunteers bear carrying out their tasks. There is currently great interest in incorporating more attractive incentive schemes for NTD volunteers. However, our results show

    The knowledge surrounding nurses' work motivation is currently insufficient, and previous studies have rarely taken into account the role of many influential background factors. This study investigates the motivation of Estonian nurses in hospitals, and how individual and organisational background factors influence their motivation to work. The study is quantitative and cross-sectional. An electronically self-reported questionnaire was used for data collection. The sample comprised of 201 Registered Nurses working in various hospital settings in Estonia. Data were analysed using descriptive statistics, two-sample Wilcoxon rank-sum (Mann-Whitney) test, Kruskal-Wallis equality-of-populations rank test and Spearman's correlation. Both extrinsic and intrinsic motivations were noted among hospital nurses. Nurses were moderately externally motivated (M = 3.63, SD = 0.89) and intrinsically strongly motivated (M = 4.98, SD = 1.03). A nurses' age and the duration of service were positively correlated with one particular area of extrinsic work motivation, namely introjected regulation (p motivation (p = 0.016) and intrinsic work motivation (p = 0.004). The findings expand current knowledge of nurses' work motivation by describing the amount and orientation of work motivation among hospital nurses and highlighting background factors which should be taken into account in order to sustain and increase their intrinsic work motivation. The instrument used in the study can be an effective tool for nurse managers to determine a nurse's reasons to work and to choose a proper motivational strategy. Further research and testing of the instrument in different countries and in different contexts of nursing is however required. © 2014 Nordic College of Caring Science.

    The acute toxicity of imidacloprid, a neonicotinoid insecticide, and zinc pyrithione (Zpt), a biocide used in anti-dandruff shampoos and protective antifouling paints, to three species of ostracods and two waterfleas, including Daphnia magna, was determined and compared under light and dark conditions. Under normal laboratory conditions, UV light had no significant influence on the outcome of toxicity bioassays, although in the case of imidacloprid both EC(50) and LC(50) calculated values were twice as high under the light as in the dark. No influence of UV light was observed on bioassays conducted with Zpt, in spite of the fast aqueous photolysis exhibited by this compound. Imidacloprid 48-h LC(50) for cladocerans (65-133mg/L) were two orders of magnitude higher than for ostracods (301-715microg/L); values of EC(50) for cladocerans and ostracods were 2-6mg/L and 3-16microg/L, respectively. Toxicity of Zpt to both ostracod and cladoceran species appears to be similar, with 48-h LC(50) in the range 137-524 and 75-197microg/L for ostracods and cladocerans, respectively, and similar values for EC(50)s. The mortality endpoint (LC(50)), however, is not a reliable predictor of the effects of imidacloprid under field situations (e.g. rice paddies), because the paralysis effect induced by this insecticide takes place at much lower concentrations than those required to cause the death of the animals: regardless of the taxa, differences as large as 100- or 600-fold were observed between the EC(50) and LC(50) for the same exposures. As a consequence, immobilization tests and EC(50) values are recommended for this class of compounds, while caution should be exercised in environmental risk assessments of this and possibly other related neonicotinoid insecticides with similar activity.

  3. Management styles and motivation.

    Science.gov (United States)

    Shearer, Dana Ann

    2012-01-01

    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.

  4. Does acute or habitual protein deprivation influence liking for monosodium glutamate?

    2017-03-15

    The umami flavour generated by monosodium glutamate (MSG) has been proposed as the marker for the presence of protein in foods. As protein is the most closely regulated macronutrient in the diet, the present study addressed whether acute protein deprivation, habitual protein intake or a combination of the two influenced liking for the taste of MSG. 24 low-restraint male participants (mean age: 22; BMI: 23) consumed either their habitual breakfast (baseline), a low protein breakfast (breakfast meal with low protein milk and milkshake) or a high protein breakfast (breakfast meal with high protein milk and milkshake) on three different days, and then evaluated the acceptability of umami (MSG), salty (NaCl) or sweet (Acesulphame K) tastes at low or high concentrations in a soup context at lunchtime. Participants also completed a habitual protein intake questionnaire (39-item protein Food Frequency Questionnaire). Liking for all tastes was higher on the low than on the high protein day, and NaCl and Acesulphame K were liked less on both protein manipulation days when compared to the no added flavour control. Habitual protein intake was not related to liking for MSG stimuli alone but habitual high protein consumers rated a high concentration of MSG as more pleasant than any other taste when in protein deficit. Overall, these findings suggest that liking for high MSG concentrations may be moderated by nutritional need in high protein consumers. Crown Copyright © 2017. Published by Elsevier Inc.

    The aims of the present study were to study the effect of different carriers and enrichments on the perceived healthiness and willingness to try functional foods; and to evaluate the effect of age, gender and motives underlying food choice. Participants had to evaluate different functional food concepts and had to answer a food choice questionnaire. Results showed that carrier products had the largest effect on consumers' perception of healthiness and willingness to try of the evaluated functional foods concepts. The highest positive relative utilities were achieved when the enrichment was a functional ingredient inherent in the product. Furthermore, gender, age and motives underlying food choice affected the preference patterns for the evaluated functional foods concepts, but it depended on the carrier and enrichment considered, suggesting that functional foods might not be accepted by all the consumers and that they could be tailored for certain groups.

  6. The motivation-based calving facility: Social and cognitive factors influence isolation seeking behaviour of Holstein dairy cows at calving

    2018-01-01

    In order to improve animal welfare it is recommended that dairy farmers move calving cows from the herd to individual pens when calving is imminent. However, the practicality of moving cows has proven a challenge and may lead to disturbance of the cows rather than easing the process of calving. One...... the cows were not able to combine a learnt response with the motivation to isolate. Dominant cows had the highest chance of calving in an individual calving pen. If an alien calf was present in the group pen or any of the individual pens, cows were less likely to calve in an individual calving pen. Future...... studies should allow cows easy access to an individual calving pen and explore what motivates pre-parturient cows to seek isolation in order to facilitate voluntary use of individual calving pens....

    Full Text Available Purpose: The world of work is evolving and the nature of relationships between knowledge workers and their employers has changed distinctly, leading to a change in the type of rewards they prefer. The nature of these preferences in the South African, industry-specific context is poorly understood. The purpose of this study was to deepen understanding of the reward preferences of Information technology (IT knowledge workers in South Africa, specifically as these relate to the attraction, retention and motivation of knowledge workers. Design: The research design included a quantitative, empirical and descriptive study of reward preferences, measured with a self-administered survey and analysed using non-parametric tests for variance between dependent and independent groups and non-parametric analysis of variance. Findings: This study found that there are specific reward preferences in knowledge workers in the IT sector in South Africa and that these preferences apply differently when related to the attraction, retention and motivation of employees. It identified the most important reward components in the competition for knowledge workers and also demonstrated that demographic characteristics play a statistically significant role in determining reward preferences. Practical implications: The study’s findings show that a holistic approach to total rewards is required, failing which, companies will find themselves facing increased turnover and jobhopping. Importantly, the study also highlights that different rewards need to form part of knowledge workers’ relationship with their employer in three different scenarios: attraction, retention and motivation.

    Full Text Available The Pedagogic practice is the staging of knowledge for consideration and recognition of acquired understanding in the academic and personal level that took place in the Commercial Technical School Manuela Beltran, showing that students present lack of motivation to learn Biology , which is expressed in the limited relationship between reality, scientific concepts together with the technical language. The experiments and innovation are left aside. This is why there is a question in relation to the didactic speech and motivation of seventh and eighth grade students towards Biology. In this way the didactic speech of the teacher has been characterized to allow the identification of elements that facilitate the teaching in terms of motivation. In the same way the space for recognizing the factors that generate in the students pleasure for the subject given, in which the games, the participation and the experiments were aspects that they will like to have in their classes. The present investigation had and interpretative paradigm and a qualitative perspective, such instruments like the nonparticipant observation,six recordings of Biology classes making analyses of information units where categories emerged, as well as a questionnaire applied to 25 students.

    Introduction : Lipopolysaccharide (LPS) is a potent inducer of the bovine acute phase response and has been widely used in research to provoke acute inflammation. An intravenous challenge with LPS elicits the endogenous synthesis and release of pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). These cytokines initiate fever and stimulate the hepatic production of acute phase proteins, such as Serum Amyloid A (SAA). Regarding the fact that immuno...

    Karimi, S.

    1988-01-01

    This study investigates the problem of poor performance among nuclear power plant inspection personnel both in training and in the field. First, a systems perspective is employed to explore the psychological processes and relevant human factors that may be associated with workers' inadequate performance. Second, two separate yet related approaches are used to clarify the definition of competence: (a) a theory-based (or top-down) approach, in which effective performance is construed as a product of a skillful, motivated person interacting with a responsive environment; and (b) an empirical (or bottom-up) approach, in which key person and context characteristics are generated based on the opinions of experts in the industry. Using a series of semistructured interviews, two empirical studies were conducted in the latter approach. Workers motivational characteristics appeared to be largely a function of their current working conditions. Overall, the results of both studies converged with the theoretical analysis emphasizing (a) the reciprocal and dynamic interplay of contextual and motivational factors influencing performance, and (b) the salient role of supervisory practices in terms of support, cooperation, and efficiency in contributing to the outcome of performance

    Full Text Available This article is the result of a dissertation about the curricular dynamics and teaching-learning process with the objective of answering the problem of School Management of the Federal Institute of Education, Science and Technology of Espírito Santo (Câmpus Vitória, specifically about the Mechanics offered by this institution. In the years 2011 to 2014, we sought to investigate the relationship between School Management and its influence on the motivation of teachers involved based on theories of Administration and Democratic Management. As a research hypothesis, it is assumed that the management model adopted by the institute has discouraged teachers from the Mechanical Engineering Course. The research was carried out through a field survey of the type of data collection, whose research instrument was the application of questionnaires and interviews to the subjects, the teachers of the course in question. It was possible to prove the hypothesis in the sense that the adopted management model has had a negative effect on the teacher motivation, generating emotional discomforts, professional insecurities, among other aspects. The final analysis showed that the management adopted, specifically in this campus, evokes a transformation to motivate teachers in their professional performance and personal fulfillment as members of the educational team of the institution.

    Fluctuations of female sex hormones during menstrual cycle influence pain perception. Endogenous pain inhibition is impaired in follicular phase of menstrual cycle. We tested the primary hypothesis that the women having surgery during their follicular phase have more acute pain and require higher opioids than those in the luteal phase, and secondarily we tested that women who have surgery during their follicular phase have more incisional pain at 3 month postoperatively. 127 adult females having laparoscopic cholecystectomy were randomized to have surgery during the luteal or follicular phase of their menstrual cycle. Standardized anesthesia and pain management regimen was given to all patients. Pain and analgesic consumption were evaluated in post-anesthesia care unit and every 4h in the first 24h. Adverse effects were questioned every 4h. Time to oral intake and ambulation were recorded. Post-surgical pain, hospital anxiety, depression scale, SF-12 questionnaire were evaluated at 1 and 3 month visits. There was no difference in acute pain scores and analgesic consumption through the 24h period, Visual Analog Scale at 24h was 1.5±1.5cm for follicular group 1.4±1.7cm for luteal group (p=0.57). Persistent postoperative pain was significantly more common one and at three month, with an incidence was 33% and 32% in the patients at follicular phase versus 16% and 12% at luteal phase, respectively. The Visual Analog Scale at one and at three month was 1.6±0.7cm and 1.8±0.8cm for follicular group and 2.7±1.3cm and 2.9±1.7cm in the luteal group (p=0.02), respectively. There were no significant differences between the groups with respect to anxiety and depression, SF-12 scores at either time. Nausea was more common in follicular-phase group (p=0.01) and oral feeding time was shorter in follicular phase (5.9±0.9h) than in luteal phase (6.8±1.9h, p=0.02). Although persistent postoperative pain was significantly more common one and three months after surgery the

    Background and Purpose Stroke imposes a major burden on patients, their families, and the national healthcare system. The purpose of this study was to determine the itemized hospital charges in acute ischemic stroke patients according to their severity by partitioning the charges in detail and then examining whether stroke severity was a significant contributor to these charges. Methods This study analyzed data of first-time acute ischemic stroke patients who had been admitted to an academic medical center between September 2003 and April 2009. The patients' demographic and clinical characteristics were analyzed descriptively, and then eight categorized hospital charges as well as the total charge were compared among patients grouped according to stroke severity, using analysis of variance. Multiple regression analyses were conducted to test the influence of stroke severity on itemized hospital charges as well as the total charge, while controlling for other related factors. Results More-severe strokes were associated with a higher total charge. Significantly higher charges were associated with patients with more-severe strokes regarding all charged items except imaging studies. The charges for imaging studies were similar across all severities of stroke. While controlling for other factors, a significant impact of stroke severity was found in both the total hospital charge and most itemized charges. Conclusions Itemized hospital charges for inpatients with acute ischemic stroke varied according to stroke severity. Stroke severity was a significant factor influencing the itemized charges of acute hospitalization of ischemic stroke patients. PMID:22523514

    (1) To investigate whether a daily acute:chronic workload ratio informs injury risk in Australian football players; (2) to identify which combination of workload variable, acute and chronic time window best explains injury likelihood. Workload and injury data were collected from 53 athletes over 2 seasons in a professional Australian football club. Acute:chronic workload ratios were calculated daily for each athlete, and modelled against non-contact injury likelihood using a quadratic relationship. 6 workload variables, 8 acute time windows (2-9 days) and 7 chronic time windows (14-35 days) were considered (336 combinations). Each parameter combination was compared for injury likelihood fit (using R 2 ). The ratio of moderate speed running workload (18-24 km/h) in the previous 3 days (acute time window) compared with the previous 21 days (chronic time window) best explained the injury likelihood in matches (R 2 =0.79) and in the immediate 2 or 5 days following matches (R 2 =0.76-0.82). The 3:21 acute:chronic workload ratio discriminated between high-risk and low-risk athletes (relative risk=1.98-2.43). Using the previous 6 days to calculate the acute workload time window yielded similar results. The choice of acute time window significantly influenced model performance and appeared to reflect the competition and training schedule. Daily workload ratios can inform injury risk in Australian football. Clinicians and conditioning coaches should consider the sport-specific schedule of competition and training when choosing acute and chronic time windows. For Australian football, the ratio of moderate speed running in a 3-day or 6-day acute time window and a 21-day chronic time window best explained injury risk.

  19. Student and Teacher Perceptions of Teacher Immediacy Behaviors and the Influence of Teacher Immediacy Behaviors on Student Motivation to Learn Science

    Science.gov (United States)

    Littlejohn, Vania

    The National Assessment on Educational Progress signals that American students are not being adequately prepared to compete globally in an ever changing scientific society. As a result, legislation mandated that all students be assessed and show proficiency in scientific literacy beginning in Grade 4 with the reauthorization of the Elementary and Secondary Education Act of 2002 also known as No Child Left Behind. Research indicates a disturbing decline in the number of U.S. students pursuing more rigorous science courses in high school, majoring in scientific areas in college, and choosing future careers in science. With a need to improve science instruction and enhance science literacy for all students, this study focuses on immediate communication behaviors of the classroom teacher as a deciding factor in the opinions of high school students towards science. The purpose of this study was to reveal high school science student perceptions of teacher communication patterns, both verbal and nonverbal, and how they influence their motivation to learn science. The researcher utilized a nonexperimental, quantitative research design to guide this study. Teacher and student data were collected using the Teacher Communication Behavior Questionnaire (TCBQ). The Student Motivation to Learn Instrument (SMLI) across gender, ethnicity, and socioeconomic status survey was used to evaluate student motivation in science. Participants were encouraged to be honest in reporting and sharing information concerning teacher communication behaviors. The data revealed that teacher immediacy behaviors, both verbal and nonverbal, were perceived differently in terms of student gender, ethnicity, and socioeconomic class. The results showed that teachers who display positive communication behaviors and use challenging questioning followed with positive responses create pathways to potentially powerful relationships. These relationships between teachers and students can lead to increased student

    Background and aims Excessive use of social networking sites (SNS) has recently been conceptualized as a behavioral addiction (i.e., “disordered SNS use”) using key criteria for the diagnosis of substance dependence and shown to be associated with a variety of impairments in psychosocial functioning, including an increased risk of problem drinking. This study sought to characterize associations between “disordered SNS use” and attitudes towards alcohol, drinking motives, and adverse consequences resulting from alcohol use in young adults. Methods Undergraduate students (n = 537, 64.0% female, mean age = 19.63 years, SD = 4.24) reported on their use of SNSs and completed the Alcohol Use Disorders Identification Test, Temptation and Restraint Inventory, Approach and Avoidance of Alcohol and Drinking Motives Questionnaires, and Drinker Inventory of Consequences. Results Respondents meeting previously established criteria for “disordered SNS use” were significantly more likely to use alcohol to cope with negative affect and to conform to perceived social norms, reported significantly more conflicting (i.e., simultaneous positive and negative) attitudes towards alcohol, and had experienced significantly more, and more frequent adverse consequences from drinking in their inter- and intrapersonal, physical, and social functioning, compared to individuals without problems related to SNS use. Discussion and conclusions Findings add to an emerging body of literature suggesting a link between excess or maladaptive SNS use and problems related to alcohol in young adults and point to emotion dysregulation and coping motives as potential shared risk factors for substance and behavioral addictions in this demographic.

    Canada's rising immigrant population has led to an increasing number of nursing students for whom English is an"additional language" (EAL). Although many of these students are successful academically, there is a persistent small number who struggle due to their limited English-language skills and their different cultural knowledge and practices. Despite the difficulties they experience, the students' desire to enter the nursing profession remains strong. A qualitative study was undertaken to identify factors that influence these students' academic performance from the perspectives of the students themselves and their instructors. Fourteen EAL nursing students were interviewed. Analysis of the interview data revealed factors that influenced the students' experiences in their nursing programs.The authors describe the students' perspectives on the challenges and motivators they encountered in their nursing programs. They also recommend strategies that could help EAL students to achieve success in their nursing studies.

    Regular activity breaks increase energy expenditure; however, this may promote compensatory eating behaviour. The present study compared the effects of regular activity breaks and prolonged sitting on appetite. In a randomised, cross-over trial, 36 healthy adults (BMI (Body Mass Index) 23.9 kg/m² (S.D. = 3.9)) completed four, two-day interventions: two with prolonged sitting (SIT), and two with sitting and 2 min of walking every 30 min (RAB). Standardized meals were provided throughout the intervention, with an ad libitum meal at the end of Day 2. Appetite and satiety were assessed throughout both days of each intervention using five visual analogue scales. The five responses were combined into a single appetite response at each time point. The area under the appetite response curve (AUC) was calculated for each day. Intervention effects for appetite response AUC and ad libitum meal intake were tested using linear mixed models. Appetite AUC did not differ between interventions (standardised effect of RAB compared to SIT: Day 1: 0.11; 95% CI: -0.28, 0.06; p = 0.212; Day 2: 0.04; 95% CI: -0.15, 0.24; p = 0.648). There was no significant difference in energy consumed at the ad libitum lunch meal on Day 2 between RAB and SIT. Interrupting prolonged sitting with regular activity breaks does not acutely influence appetite or volume of food consumed, despite inferred increases in energy expenditure. Longer-term investigation into the effects of regular activity breaks on energy balance is warranted.

    Full Text Available Background: Matrix metalloproteinases (MMPs are a family of enzymes important for the resorption of extracellular matrices, control of vascular remodeling and repair. Increased activity of MMP2 has been demonstrated in heart failure, and in acutely decompensated heart failure (ADHF a decrease in circulating MMPs has been demonstrated along with successful treatment. Objective: Our aim was to test the influence of spironolactone in MMP2 levels. Methods: Secondary analysis of a prospective, interventional study including 100 patients with ADHF. Fifty patients were non-randomly assigned to spironolactone (100 mg/day plus standard ADHF therapy (spironolactone group or standard ADHF therapy alone (control group. Results: Spironolactone group patients were younger and had lower creatinine and urea levels (all p < 0.05. Baseline MMP2, NT-pro BNP and weight did not differ between spironolactone and control groups. A trend towards a more pronounced decrease in MMP2 from baseline to day 3 was observed in the spironolactone group (-21 [-50 to 19] vs 1.5 [-26 to 38] ng/mL, p = 0.06. NT-pro BNP and weight also had a greater decrease in the spironolactone group. The proportion of patients with a decrease in MMP2 levels from baseline to day 3 was also likely to be greater in the spironolactone group (50% vs 66.7%, but without statistical significance. Correlations between MMP2, NT-pro BNP and weight variation were not statistically significant. Conclusion: MMP2 levels are increased in ADHF. Patients treated with spironolactone may have a greater reduction in MMP2 levels.

    Full Text Available Aims. This prospective study aims to identify patient characteristics as predictors for treatment outcome during inpatient detoxification treatment for drug and alcohol dependent patients. Methods. A mixed gender sample of 832 consecutively admitted drug and alcohol dependent patients were interviewed by an experienced physician. The impact of a variety of factors concerning social environment, therapy motivation, impulsivity related variables, medical history, and addiction severity on treatment outcome was examined. Results. 525 (63.1% of the patients completed detoxification treatment whereas 307 (36.9% dropped out prematurely. Being female, living in a partnership, having children, being employed, and having good education were predictive for a positive outcome. Family, health, the fear of losing the job, prosecution, and emergency admission were significant motivational predictors for treatment outcome. Being younger, history of imprisonment, and the number of previous drop-outs were predictive for a negative outcome. Conclusions. Variables concerning social environment and the number of previous drop-outs have been identified as best predictors for treatment outcome. Socially stable patients benefit from the current treatment setting and treatment shall be adapted for patients with negative predictors. Treatment may consequently be tailored with respect to intervention type, duration, and intensity to improve the outcome for those patients that fulfil criteria with negative impact on treatment retention.

    Full Text Available Introduction: Acute pancreatitis is often a relapsing condition, particularly when its triggering factor persists. Our goal is to determine the recurrence rate of acute biliary pancreatitis after an initial episode, and the time to relapse, as well as to identify the risk factors for recurrence. Material and method: We included all patients admitted for a first acute gallstone pancreatitis event during four years. Primary endpoints included readmission for recurrence and time to relapse. Results: We included 296 patients admitted on a total of 386 occasions. The incidence of acute biliary pancreatitis in our setting is 17.5/100,000 population/year. In all, 19.6% of pancreatitis were severe (22.6% of severe acute pancreatitis for first episodes versus 3.6% for recurring pancreatitis, with an overall mortality of 4.4%. Overall recurrence rate was 15.5%, with a median time to relapse of 82 days. In total, 14.2% of patients relapsed after an acute pancreatitis event without cholecystectomy or endoscopic retrograde cholangio-pancreatography. Severe acute pancreatitis recur in 7.2% of patients, whereas mild cases do so in 16.3%, this being the only risk factor for recurrence thus far identified. Conclusions: Patients admitted for pancreatitis should undergo cholecystectomy as soon as possible or be guaranteed priority on the waiting list. Otherwise, endoscopic retrograde cholangio-pancreatography with sphincterotomy may be an alternative to surgery for selected patients.

    Full Text Available The purpose of the study was to determine the level of proinflammatory cytokines: IL-12, IL-8 and IFNγ, neopterin and lipopolysaccharide-binding protein in the serum of patients with acute brucellosis before and after antibiotic therapy. The clinical data from 32 patients with laboratory-confirmed diagnosis — “acute brucellosis” admitted to the diagnosis, treatment and examination of occupational diseases brucellosis GBUZ SC “City Clinical Hospital No. 2”, the city of Stavropol were used in the study. The concentrations IL-12, IL-8, IFNγ cytokines and acute-phase proteins in serum was determined by ELISA. In the acute phase of brucellosis infection (before treatment had high levels of pro-inflammatory cytokines IL-8 and IFNγ, but despite holding a course of antibiotic treatment in the serum of patients with preserved high levels of IL-8, indicative of active inflammation in the absence of clinical manifestations. IL-12 level, a key cytokine in the initiation of lymphocyte-dependent immune response was lower than in the control group. Evaluation of the cytokine status (IL-8, IL-12, IL-18 and proteins of acute inflammation phase (neopterin and lipopolysaccharide-binding protein will provide valuable information for monitoring the effect of pharmacotherapy of acute brucellosis. Indicators of lipopolysaccharide-binding protein and neopterin in the serum of patients with brucellosis should be considered as a marker of inflammatory activity and as a predictor of outcome of acute brucellosis.

    Community health workers (CHWs) in Mozambique (known as Agentes Polivalentes Elementares (APEs)) are key actors in providing health services in rural communities. Supervision of CHWs has been shown to improve their work, although details of how it is implemented are scarce. In Mozambique, APE supervision structures and scope of work are clearly outlined in policy and rely on supervisors at the health facility of reference. The aim of this study was to understand how and which aspects of supervision impact on APE motivation and programme implementation. Qualitative research methodologies were used. Twenty-nine in-depth interviews were conducted to capture experiences and perceptions of purposefully selected participants. These included APEs, health facility supervisors, district APE supervisors and community leaders. Interviews were recorded, translated and transcribed, prior to the development of a thematic framework. Supervision was structured as dictated by policy but in practice was irregular and infrequent, which participants identified as affecting APE's motivation. When it did occur, supervision was felt to focus more on fault-finding than being supportive in nature and did not address all areas of APE's work - factors that APEs identified as demotivating. Supervisors, in turn, felt unsupported and felt this negatively impacted performance. They had a high workload in health facilities, where they had multiple roles, including provision of health services, taking care of administrative issues and supervising APEs in communities. A lack of resources for supervision activities was identified, and supervisors felt caught up in administrative issues around APE allowances that they were unable to solve. Many supervisors were not trained in providing supportive supervision. Community governance and accountability mechanisms were only partially able to fill the gaps left by the supervision provided by the health system. The findings indicate the need for an improved

    Ecotoxicological models generally have large data requirements and are frequently based on existing information from diverse sources. Standardizing data for toxicological models may be necessary to reduce extraneous variation and to ensure models reflect intrinsic relationships. However, the extent to which data standardization is necessary remains unclear, particularly when data transformations are used in model development. An extensive acute toxicity database was compiled for aquatic species to comprehensively assess the variation associated with acute toxicity test type (e.g., flow-through, static), reporting concentrations as nominal or measured, and organism life stage. Three approaches were used to assess the influence of these factors on log-transformed acute toxicity: toxicity ratios, log-linear models of factor groups, and comparison of interspecies correlation estimation (ICE) models developed using either standardized test types or reported concentration type. In general, median ratios were generally less than 2.0, the slopes of log-linear models were approximately one for well-represented comparisons, and ICE models developed using data from standardized test types or reported concentrations did not differ substantially. These results indicate that standardizing test data by acute test type, reported concentration type, or life stage may not be critical for developing ecotoxicological models using large datasets of log-transformed values.

    The inability to communicate effectively in a common language can jeopardize clinicians' efforts to provide quality patient care. Professional medical interpreters (PMIs) can help provide linguistically appropriate health care, in particular for the >25 million Americans who identify speaking English less than very well. We aimed to evaluate the relationship between use of PMIs and quality of acute ischemic stroke care received by patients who preferred to have their medical care in languages other than English. We analyzed data from 259 non-English-preferring acute ischemic stroke patients who participated in the American Heart Association Get With The Guidelines-Stroke program at our hospital from January 1, 2003, to April 30, 2014. We used descriptive statistics and logistic regression models to examine associations between involvement of PMIs and patients' receipt of defect-free stroke care. A total of 147 of 259 (57%) non-English-preferring patients received PMI services during their hospital stays. Multivariable analyses adjusting for other socioeconomic factors showed that acute ischemic stroke patients who did not receive PMIs had lower odds of receiving defect-free stroke care (odds ratio: 0.52; P =0.04). Our findings suggest that PMIs may influence the quality of acute ischemic stroke care. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

  15. The experimental investigation of fibrinolytic system under the influence of flocalin in conditions of acute hypoxic kidney injury

    2017-08-01

    Full Text Available In the experiments on rats subjected to acute hypoxic histochemical nephropathy, caused by sodium nitrite and 2,4-dinitrophenol, fibrinolytic activities of blood plasma, urine, renal cortex, medulla, and papilla after treatment with flocalin – the activator of KATP channels, were studied­. It was shown that in the conditions of acute kidney hypoxic injury flocalin administration resulted in the increase and essential restoration of fibrinolysis in blood plasma diminished under hypoxia, which was due to the growth of non-enzymatic fibrinolysis, whereas in urine and renal medulla the appreciable increase of enzymatic fibrinolytic activity took place. Moreover, the treatment of hypoxic nephropathy animals by flocalin resulted in the marked restoration of kidney ion regulatory and protein excretory functions that proves the positive influence of KATP channels activation on the one of the biochemical mechanisms of acute kidney injury as well as the protective effect of flocalin in relation to tubular cells of nephron. The obtained results testify to the beneficial effects of KATP channels activation in the conditions of acute hypoxic kidneys injury.

    Gamez-Djokic, Monica; Molden, Daniel

    2016-09-20

    Past research suggests that deontological judgments, which condemn deliberate harm no matter what the beneficial consequences, typically arise from emotional and intuitive reactions to the harm, whereas utilitarian judgments, which acknowledge the potential benefits of deliberate harm, typically arise from rational deliberation about whether these benefits outweigh the costs. The present research explores whether specific motivational orientations might, at times, increase the likelihood of deontological judgments without increasing emotional reactions. A meta-analysis of 10 newly conducted studies indicated that, compared with when focused on advancement (promotion), when people were focused on security (prevention) they made stronger deontological judgments in hypothetical moral dilemmas. Moreover, this effect could not be explained by participants' differing emotional reactions to the dilemmas when prevention-focused, but instead mirrored reports of their explicit reasoning. Implications for expanding current models of deontological and utilitarian moral judgment are discussed. © 2016 by the Society for Personality and Social Psychology, Inc.

    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.

  18. The motivation-based calving facility: Social and cognitive factors influence isolation seeking behaviour of Holstein dairy cows at calving

    Herskin, Mette S.; Jensen, Margit Bak

    2018-01-01

    In order to improve animal welfare it is recommended that dairy farmers move calving cows from the herd to individual pens when calving is imminent. However, the practicality of moving cows has proven a challenge and may lead to disturbance of the cows rather than easing the process of calving. One solution may be to allow the cow to seek isolation prior to calving. This study examined whether pre-parturient dairy cows will isolate in an individual calving pen placed in a group calving setting and whether a closing gate in this individual calving pen will cause more cows to isolate prior to calving. Danish Holstein cows (n = 66) were housed in groups of six in a group pen with access to six individual calving pens connected to the group area. Cows were trained to use one of two isolation opportunities i.e. individual calving pens with functional closing gates (n = 35) allowing only one cow access at a time, or individual calving pens with permanently open gates allowing free cow traffic between group area and individual pen (n = 31). The response variables were calving site, calving behaviour and social behaviour. Unexpectedly, a functional gate did not facilitate isolation seeking, perhaps because the cows were not able to combine a learnt response with the motivation to isolate. Dominant cows had the highest chance of calving in an individual calving pen. If an alien calf was present in the group pen or any of the individual pens, cows were less likely to calve in an individual calving pen. Future studies should allow cows easy access to an individual calving pen and explore what motivates pre-parturient cows to seek isolation in order to facilitate voluntary use of individual calving pens.

    There is little evidence on the prognostic influence of intravenous nitrates in patients with acute heart failure. Our purpose was to determine the influence of this treatment on early mortality and new visits. Prospective, multicenter cohort study of patients with acute heart failure in an emergency room during 2 periods (May 2009 and November-December 2011). Patients with systolic blood pressure > 110mmHg were included, grouped according to whether they received intravenous nitroglycerin or not. Endpoints were mortality at 3, 7, 14, and 30 days and new visits at 30 days. The propensity score was estimated by logistic regression to determine the prognostic influence of the treatment. We included 3178 of 4897 individuals. A total of 308 (9.7%) had died within 30 days and 465 (17%) attended new visits. The mean (standard deviation) age was 79.5 (10.0) years, and 796 (25%) patients received intravenous nitrates. After matching, there were 685 individuals in each group. The hazard ratio for 30-day mortality with nitrates was 1.21 (95% confidence interval, 0.87-1.70) and was 0.93 for new visits (95% confidence interval, 0.71-1.22). The results were similar for mortality at 3, 7, and 14 days (hazard ratio = 1.05 [95% confidence interval, 0.56-1.96], hazard ratio = 1.20 [95% confidence interval, 0.74-1.94], and hazard ratio = 1.23 [95% confidence interval, 0.82-1.84], respectively). In the presence of hypertensive pulmonary edema, the nitrates group showed a hazard ratio of 0.88 (95% confidence interval, 0.47-1.63) for 30-day mortality. Intravenous nitrates do not influence early mortality or new visits in patients with acute heart failure. Copyright © 2014 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

    Noninvasive positive pressure has been used to treat several diseases. However, the physiological response of the cardiac autonomic system during bilevel positive airway pressure (Bilevel) remains unclear. The aim of this study was to evaluate the heart rate variability (HRV) during Bilevel in young healthy subjects. Twenty men underwent 10-minute R-R interval recordings during sham ventilation (SV), Bilevel of 8-15 cmH(2)O and Bilevel of 13-20 cmH(2)O. The HRV was analyzed by means of the parallel R-R interval (mean R-Ri), the standard deviation of all R-Ri (SDNN), the root mean square of the squares of the differences between successive R-Ri (rMSSD), the number of successive R-Ri pairs that differ by more than 50 milliseconds (NN50), the percentage of successive R-Ri that differ by more than 50 milliseconds (pNN50), the low frequency (LF), the high frequency (HF) and SD1 and SD2. Additionally, physiological variables, including blood pressure, breathing frequency and end tidal CO(2), were collected. Repeated-measures ANOVA and Pearson correlation were used to assess the differences between the three studied conditions and the relationships between the delta of Bilevel at 13-20 cmH(2)O and sham ventilation of the HRV indexes and the physiological variables, respectively. The R-Ri mean, rMSSD, NN50, pNN50 and SD1 were reduced during Bilevel of 13-20 cmH(2)O as compared to SV. An R-Ri mean reduction was also observed in Bilevel of 13-20 cmH(2)O compared to 8-15 cmH(2)O. Both the R-Ri mean and HF were reduced during Bilevel of 8-15 cmH(2)O as compared to SV, while the LF increased during application of Bilevel of 8-15 cmH(2)O as compared to SV. The delta (between Bilevel at 13-20 cmH(2)O and sham ventilation) of ETCO(2) correlated positively with LF, HF, the LF/HF ratio, SDNN, rMSSD and SD1. Acute application of Bilevel was able to alter the cardiac autonomic nervous system, resulting in a reduction in parasympathetic activity and an increase in sympathetic activity

    This study evaluated the clinical influence of distal entry tears in acute type B aortic dissection (ATBAD) after thoracic endovascular aortic repair (TEVAR). From August 2009 to December 2014, the clinical outcomes of 130 patients who underwent TEVAR for ATBAD were retrospectively analyzed. According to whether distal entry tears existed after TEVAR, patients were divided into group A (n = 25, absence of distal entry tears) and group B (n = 105, presence of distal entry tears). We evaluated clinical outcomes, including mortality and morbidity in early and late follow-up, as well as aortic remolding. Late aortic events were defined as aortic dissection-related events occurring >30 days from the initial TEVAR procedures, which consisted of endoleak, retrograde type A aortic dissection, aortic enlargement, late rupture, repeat dissection, and stent-induced new entry tear. The study comprised 130 patients (114 men [87.7%] and 16 women [12.3%)] with a mean age of 53.71 years. The 30-day mortality was 3.1%, and early morbidity included type I endoleak, 3.1%, organ failure, 3.8%; stroke, 3.1%; spinal cord ischemia, 0%; and early rupture 1.5%. The overall survival rate by Kaplan-Meier analysis at 1, 3, and 5 years was 93.8%, 89.5%, and 79.2%, respectively. There were no significant differences in early morbidity and 30-day mortality and late survival between group A and group B. However, group A had a significantly lower rate of late aortic events than group B (P = .028 by log-rank test). Meanwhile, group A had better aortic remolding than group B in complete thrombosis of the thoracic aorta at 12 months postoperatively (100% vs 83.5%; P = .029). This study demonstrated that TEVAR for ATBAD had low perioperative morbidity and mortality and satisfactory midterm outcome. Distal entry tears increase the occurrence of late aortic events and inhibit aortic remolding but do not have a significantly negative effect on late survival. Repairing all entry tears to restore

    The goal of this study is to evaluate the response of physiological variables to acute normobaric hypoxia compared to normoxia and its influence on the lactate turn point determination according to the three-phase model of energy supply (Phase I: metabolically balanced at muscular level; Phase II: metabolically balanced at systemic level; Phase III: not metabolically balanced) during maximal incremental exercise. Ten physically active (VO2max 3.9 [0.49] l·min(-1)), healthy men (mean age [SD]: 25.3 [4.6] yrs.), participated in the study. All participants performed two maximal cycle ergometric exercise tests under normoxic as well as hypoxic conditions (FiO2 = 14%). Blood lactate concentration, heart rate, gas exchange data, and power output at maximum and the first and the second lactate turn point (LTP1, LTP2), the heart rate turn point (HRTP) and the first and the second ventilatory turn point (VETP1, VETP2) were determined. Since in normobaric hypoxia absolute power output (P) was reduced at all reference points (max: 314 / 274 W; LTP2: 218 / 184 W; LTP1: 110 / 96 W), as well as VO2max (max: 3.90 / 3.23 l·min(-1); LTP2: 2.90 / 2.43 l·min(-1); LTP1: 1.66 / 1.52 l·min(-1)), percentages of Pmax at LTP1, LTP2, HRTP and VETP1, VETP2 were almost identical for hypoxic as well as normoxic conditions. Heart rate was significantly reduced at Pmax in hypoxia (max: 190 / 185 bpm), but no significant differences were found at submaximal control points. Blood lactate concentration was not different at maximum, and all reference points in both conditions. Respiratory exchange ratio (RER) (max: 1.28 / 1.08; LTP2: 1.13 / 0.98) and ventilatory equivalents for O2 (max: 43.4 / 34.0; LTP2: 32.1 / 25.4) and CO2 (max: 34.1 / 31.6; LTP2: 29.1 / 26.1) were significantly higher at some reference points in hypoxia. Significant correlations were found between LTP1 and VETP1 (r = 0.778; p better the performance of the athletes the higher is the effect of hypoxiaThe HRTP and LTP2 are

    When people evaluate the strength of an argument, their motivations are likely to influence the evaluation. However, few studies have specifically investigated the influences of motivational factors on argument evaluation. This study examined the effects of defence and accuracy motivations on argument evaluation. According to the compatibility between the advocated positions of arguments and participants' prior beliefs and the objective strength of arguments, participants evaluated four types of arguments: compatible-strong, compatible-weak, incompatible-strong, and incompatible-weak arguments. Experiment 1 revealed that participants possessing a high defence motivation rated compatible-weak arguments as stronger and incompatible-strong ones as weaker than participants possessing a low defence motivation. However, the strength ratings between the high and low defence groups regarding both compatible-strong and incompatible-weak arguments were similar. Experiment 2 revealed that when participants possessed a high accuracy motivation, they rated compatible-weak arguments as weaker and incompatible-strong ones as stronger than when they possessed a low accuracy motivation. However, participants' ratings on both compatible-strong and incompatible-weak arguments were similar when comparing high and low accuracy conditions. The results suggest that defence and accuracy motivations are two major motives influencing argument evaluation. However, they primarily influence the evaluation results for compatible-weak and incompatible-strong arguments, but not for compatible-strong and incompatible-weak arguments. © 2016 The British Psychological Society.

    Background and Aims Clinical manifestations of hepatitis A virus (HAV) infection vary from mild to fulminant hepatic failure (FHF) in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA) and evaluated predictive factors for severe acute hepatitis (s-AH). Methods We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT) of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128). Other patients were defined as mild acute hepatitis (m-AH) (n = 642). Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer. Results In a multivariate analysis, age (HR = 1.042, P = 0.041), peak creatinine (HR = 4.014, P = 0.001), bilirubin (HR = 1.153, P = 0.003), alanine aminotransferase (ALT) (HR = 1.001, Phepatitis A.

    Objective This study examined the impact of motivational interviewing (MI) counseling time on self-efficacy to practice safer sex for people living with HIV/AIDS (PLWHA). Methods In 4 month intervals we followed a cohort of 490 PLWHA for 12 months. We conducted hierarchical linear regression models to examine changes in safer sex self-efficacy when participants received zero, low to moderate (5–131 minutes) and high (132–320 minutes) doses of MI time. We conducted a similar analysis using number of counseling sessions as the predictor variable. Results Participants with low to moderate doses of MI counseling had 0.26 higher self-efficacy scores than participants with zero MI time (p=0.01). Also, they had 0.26 lower self-efficacy scores than participants with high amounts of MI time (p=0.04). Participants with high doses of MI had a 0.5 higher self-efficacy score than participants with zero amount of MI time (p<0.0001). Participants who received 3–4 counseling sessions had 0.41 greater self-efficacy scores than participants who did not receive any sessions (p<0.0001) but did not differ from participants receiving 1–2 sessions. Conclusion MI time is a key to enhancing safer sex self-efficacy among PLWHA. Practice Implications Safer sex self-efficacy improves the more MI counseling time and sessions PLWHA receive.

  13. Color in context: psychological context moderates the influence of red on approach- and avoidance-motivated behavior.

    Directory of Open Access Journals (Sweden)

    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.

    To compare medication adherence and readmissions in patients who received usual care vs. patient-centred interventions. Medication adherence is a complex behaviour that may be improved with patient-centred strategies. A non-concurrent convenience sample of 303 hospitalised patients received either usual care (n = 98) or patient-centred interventions (n = 205). Intervention patients received teach-back and medication tools (n = 137) or motivational interviewing (n = 68). Data were collected at discharge (T1), at 48-72 hours (T2) and 30 days after discharge (T3). No significant differences were found in medication adherence, therapeutic alliance, patients' experience and readmissions between groups. Patients in the motivational interview group reported lower confidence with medication adherence at T1 (P = 0.01) and T2 (P = 0.00) than the patient-centred intervention group. Motivational interviewing was a significant predictor (β = -1.55, P = 0.01, OR 0.21, 95% CI 0.06, 0.72) of fewer readmissions. Overall, patients reported very low levels of non-adherence and very high levels of confidence and importance of medication adherence. Medication adherence continues to be an important area for clinical inquiry. For those patients who lack confidence for medication adherence, comprehensive patient-centred strategies such as motivational interviewing may improve treatment outcomes. © 2014 John Wiley & Sons Ltd.

    The severity of acute radiation injury to small bowel mucosa in rats was studied as a function of lumenal pH at the time of irradiation. Indices of injury were surviving crypt numbers, mucosal height and mucous-containing goblet cells. Animals were sacrificed 5 days postirradiation. For all three parameters and on each day postirradiation, the pH 9 segment showed less damage than segments with lumenal pH 7 or 5. The authors conclude that lumenal pH at the time of irradiation plays a significant role in the severity of acute mucosal injury. Alkaline pH is relatively protective. (author)

    The tubular permeability to phosphate of the different segments of the rat nephron and the influence of parathyroid hormone on such a permeability were investigated. Tracer microinjections of 32 P and 3 H inulin were performed in control, acutely thyroparathyroidectomized (TPTX) and TPTX + PTH animals undergoing saline diuresis. In order to estimate the 32 P reabsorption capacity of the proximal convoluted tubule (PCT), the loop of Henle and the terminal part of the nephron, microinjections were performed in early proximal, late proximal and early distal tubules respectively. The results reported confirm that the renal phosphate reabsorption is under PTH control [fr

    In the current study, the possible association of positivity (POS), recently defined as general disposition to view life under positive outlook, with immune markers and post-stress modifications, was analyzed. Circulating lymphocyte subsets and serum cytokine levels were evaluated before and after a standard mild acute stress test, in 41 healthy students, previously selected by a questionnaire for their level of POS (high [POS-H] and low [POS-L]). The CD3 + and CD4 + cell frequency was higher in the POS-H students before and after acute stress. CD4 + subpopulation analysis revealed baseline higher terminally differentiated frequency in the POS-H, whereas higher effector memory frequency was present in the POS-L students. Moreover, the frequency of post-stress B cells was higher in the POS-H students. The mild-stress test was associated to an increase of the IL-10 mean values, while mean values of the other cytokines tested did not change significantly. It is tempting to speculate that IL-10 may work as biomarker of response to acute mild stress and that POS-H may be associated to a better capacity of the immune system to contrast the disturbing effects of mild acute stress. Yet further studies on lymphocyte subset absolute number and function of larger and different populations are needed to definitively prove these preliminary observations.

    When children experience habitual peer difficulties, adults often remind them that many people care about them. How do such reminders of support impact children's emotional responses to acute experiences of peer disapproval? Intuitively, support reminders would exert compensatory effects attenuating the emotional impact of acute disapproval. Theory suggests, however, that support reminders might also lead to contrast effects magnifying the emotional impact of acute disapproval, especially among socially vulnerable children. These opposing perspectives were pitted against each other. In 2 experiments, children (aged 9-13, M(age) = 11.5) were randomly assigned to reflect on their relationships with either supportive others (support condition) or mere acquaintances (control condition). Children experienced acute peer disapproval immediately after (Experiment 1) or before (Experiment 2) the manipulated support reminder. Among children who experienced higher levels of peer difficulties in their daily life, the support reminder increased externalized emotional reactivity and decreased internalized emotional recovery following disapproval. Thus, consistent with emotional contrast theory, support reminders magnified the disapproval-based emotional responses of socially vulnerable children. (c) 2015 APA, all rights reserved).

    Background: Matrix metalloproteinases (MMPs) are a family of enzymes important for the resorption of extracellular matrices, control of vascular remodeling and repair. Increased activity of MMP2 has been demonstrated in heart failure, and in acutely decompensated heart failure (ADHF) a decrease in circulating MMPs has been demonstrated along with successful treatment. Objective: Our aim was to test the influence of spironolactone in MMP2 levels. Methods: Secondary analysis of a prospective, interventional study including 100 patients with ADHF. Fifty patients were non-randomly assigned to spironolactone (100 mg/day) plus standard ADHF therapy (spironolactone group) or standard ADHF therapy alone (control group). Results: Spironolactone group patients were younger and had lower creatinine and urea levels (all p enzimas importantes para a reabsorção da matriz extracelular e controle do remodelamento e da reparação vasculares. Demonstrou-se aumento da atividade de MMP2 na insuficiência cardíaca, e, na insuficiência cardíaca agudamente descompensada (ICAD), demonstrou-se uma diminuição nas MMPs circulantes juntamente com o tratamento bem-sucedido. Objetivos: Testar a influência da espironolactona nos níveis de MMP2. Métodos: Análise secundária de estudo prospectivo, intervencionista, incluindo 100 pacientes com ICAD, 50 designados não aleatoriamente para o uso de espironolactona (100 mg/dia) mais terapia padrão para ICAD (grupo espironolactona) e 50 para terapia padrão para ICAD apenas (grupo controle). Resultados: Os pacientes do grupo espironolactona eram mais jovens e tinham níveis mais baixos de creatinina e ureia (todos p < 0,05). Os valores basais de MMP2, NT-pro BNP e peso não diferiram entre os grupos espironolactona e controle. Observou-se tendência para uma redução mais pronunciada na MMP2 do basal para o dia 3 no grupo espironolactona (-21 [-50 a 19] vs 1,5 [-26 a 38] ng/ml, p = 0,06).

    ABSTRACT Objective: To compare the incidence and intensity of acute adverse effects and the variation in the temperature of facial skin by thermography after the use of noninvasive ventilation (NIV). Methods: We included 20 healthy volunteers receiving NIV via oronasal mask for 1 h. The volunteers were randomly divided into two groups according to the ventilatory mode: bilevel positive airway pressure (BiPAP) or continuous positive airway pressure (CPAP). Facial thermography was performed in order to determine the temperature of the face where it was in contact with the mask and of the nasal dorsum at various time points. After removal of the mask, the volunteers completed a questionnaire about adverse effects of NIV. Results: The incidence and intensity of acute adverse effects were higher in the individuals receiving BiPAP than in those receiving CPAP (16.1% vs. 5.6%). Thermographic analysis showed a significant cooling of the facial skin in the two regions of interest immediately after removal of the mask. The more intense acute adverse effects occurred predominantly among the participants in whom the decrease in the mean temperature of the nasal dorsum was lower (14.4% vs. 7.2%). The thermographic visual analysis of the zones of cooling and heating on the face identified areas of hypoperfusion or reactive hyperemia. Conclusions: The use of BiPAP mode was associated with a higher incidence and intensity of NIV-related acute adverse effects. There was an association between acute adverse effects and less cooling of the nasal dorsum immediately after removal of the mask. Cutaneous thermography can be an additional tool to detect adverse effects that the use of NIV has on facial skin. PMID:28538774

    Analysis of the distribution of reaction times (RTs) in behavioral tasks can illustrate differences attributable to changes in attention, even when no change in mean RT is observed. Detrimental attentional effects of both acute and chronic exposure to alcohol may therefore be revealed by fitting RT data to an ex-Gaussian probability density function which identifies the proportion of long-RT responses. Adolescent male rhesus macaques completed a 5-choice serial reaction time task (5CSRT) after acute alcohol consumption (up to 0.0, 1.0 and 1.5 g/kg). Monkeys were next divided into chronic alcohol (N = 5) and control groups (N = 5); the experimental group consumed 1.5-3.0 g/kg alcohol for 200 drinking sessions. Unintoxicated performance in the 5CSRT task was determined systematically across the study period and the effect of acute alcohol was redetermined after the 180th drinking session. The effect of extended abstinence from chronic alcohol was determined across 90 days. Acute alcohol exposure dose-dependently reduced the probability of longer RT responses without changing the mean or the standard deviation of the RT distribution. The RT distribution of control monkeys tightened across 10 months whereas that of the chronic alcohol group was unchanged. Discontinuation from chronic alcohol increased the probability of long RT responses with a difference from control animals observed after 30 days of discontinuation. Alcohol consumption selectively affected attention as reflected in the probability of long RT responses. Acute alcohol consumption focused attention, chronic alcohol consumption impaired the maturation of attention across the study period and alcohol discontinuation impaired attention.

  17. Motivating pharmacists.

    Donehew, G R

    1979-01-01

    Although pharmacists are developing interest in many types of pharmacy practice, they are still spending the bulk of their time in the prescription dispensing process. Any effort to provide motivation must consider the prescription dispensing process. The pharmacy literature includes only a few studies that dealt with pharmacists as people. The studies usually showed that pharmacists basically were unhappy with their jobs. In developing a motivational climate for pharmacists, pharmacy supervisors have several concepts to consider: the hierarchy of needs by Maslow; the expectancy theory by Hampton; the gygiene-motivator theory by Herzberg; and the Theory Y management approach by McGregor. Because pharmacists must be induced to enter and remain in an organization, supervisors should be aware of the need to use any technique available in developing a motivational climate.

    Glutamate excitotoxicity, metabolic rate and inflammatory response have been associated to the deleterious effects of temperature during the acute phase of stroke. So far, the association of temperature with these mechanisms has been studied individually. However, the simultaneous study of the influence of temperature on these mechanisms is necessary to clarify their contributions to temperature-mediated ischemic damage. We used non-invasive Magnetic Resonance Spectroscopy to simultaneously measure temperature, glutamate excitotoxicity and metabolic rate in the brain in animal models of ischemia. The immune response to ischemia was measured through molecular serum markers in peripheral blood. We submitted groups of animals to different experimental conditions (hypothermia at 33°C, normothermia at 37°C and hyperthermia at 39°C), and combined these conditions with pharmacological modulation of glutamate levels in the brain through systemic injections of glutamate and oxaloacetate. We show that pharmacological modulation of glutamate levels can neutralize the deleterious effects of hyperthermia and the beneficial effects of hypothermia, however the analysis of the inflammatory response and metabolic rate, demonstrated that their effects on ischemic damage are less critical than glutamate excitotoxity. We conclude that glutamate excitotoxicity is the key molecular mechanism which is influenced by body temperature during the acute phase of brain stroke.

Day care service may have the potential to increase caregivers’ positive experiences and meaning-focused coping, and positively influence interpersonal relationships between those giving care and those receiving care. The aim of this study was to gain knowledge about family caregivers’ experiences of meaning in their caring role. Additionally, the influence of day care services on caregivers’ experiences and motivation in their caregiving role is explored. Methods: A qualitative design based on individual interviews was used. The interviews were analyzed using a narrative method and a case study approach. Findings: Family caregivers’ roles and coping strategies were related to their relational ties. Caregivers had to make decisions about whether to enhance, maintain, or let go of emotional ties to find a good balance between meeting their own needs and the needs of the person with dementia. Family caregivers reported that day care positively influenced their “relationship-oriented coping” and experience of meaning. Conclusion: Finding meaning in the role of a family caregiver for persons with dementia is closely connected to the caregivers’ own values and goals. Finding a balance between attending to their own needs and the needs of the person with dementia is crucial. Day care has the potential to increase

    Outliers account for a large amount of technology utilization and resources consumed in acute care, despite accounting for only a small portion of the total patient population. Most current efforts to reduce costs, such as re-engineering and downsizing, are nonspecific methods of controlling costs. Focusing efforts in high-cost areas, such as outlier management, is much more likely to improve patient care and improve the use of technology while achieving real advances in cost control. Most hospitals will have to build an infrastructure to support outlier management, which includes developing clinical staff. These processes will take time and careful planning, but they are essential for the effective management of technology utilization and outliers. The failure to employ focused efforts like outlier management will result in the superficial treatment of high costs in acute care. The benefit to employing these methods leads to the best use of technology and the improved management of a difficult patient population.

    What is the central question of the study? The purpose of this study was to determine the effect of age and fitness on the vascular response to acute inflammation in younger and older adults. What is the main finding and its importance? In older adults, cardiorespiratory fitness level has a differential impact on endothelial function following acute inflammation: older moderately fit adults have a greater decrease in endothelial function, similar to that of younger adults. These findings have important implications of further supporting the beneficial effects of higher cardiorespiratory fitness in maintaining vascular reactivity and the ability to respond to stressors. Inflammation is associated with greater risk of cardiovascular events and reduced vascular function with aging. Higher cardiorespiratory fitness is associated with lower risk of cardiovascular events and better vascular function. We evaluated the role of fitness in the vascular response to acute inflammation in 26 younger (YA) and 62 older (OA) adults. We used an influenza vaccine to induce acute inflammation. Blood pressure, flow-mediated dilation (FMD), augmentation index (AIx@75), carotid elastic modulus (Ep) and inflammatory markers were measured before and 24-hours after vaccination. VO 2 peak was measured via a treadmill test. Fit was defined as a VO 2 peak greater than the age- and sex-determined 50 th percentile according to the American College of Sports Medicine. An interaction effect existed for the FMD response during acute inflammation (p fit: 11.5 ± 1.8 to 9.2 ± 1.3%; moderately fit: 11.9 ± 0.8 to 9.0 ± 0.8%) and moderately fit OA (7.5 ± 1.0 to 3.9 ± 0.8%) had similar reductions in FMD at 24h (p fit OA did not reduce FMD at 24h (5.5 ± 0.4 to 5.2 ± 0.5%, p > 0.05). The reduction in FMD in YA was similar between fitness groups (p > 0.05). All groups had similar reductions in mean arterial pressure and increases in inflammatory markers. AIx@75 and Ep did not

    Since 2007 to address a high burden, integration of acute malnutrition has been promoted in Niger. This paper studies factors that influenced the integration process of acute malnutrition into the Niger national health system.We used qualitative methods of observation, key informant interviews and focus group discussions at national level, two districts and nine communities selected through convenience sampling, as well as document review. A framework approach constructed around the problem, intervention, adoption system, health system characteristics and broad context guided the analysis. Data were recorded on paper, transcribed in a descriptive record, coded by themes deduced by building on the framework and triangulated for comprehensiveness.Key facilitating factors identified were knowledge and recognition of the problem helped by accurate information; effectiveness of decentralized continuity of care; compatibility with goals, support and involvement of health actors; and leadership for aligning policies and partnerships and mobilizing resources within a favourable political context driven by multisectoral development goals. Key hindering factors identified were not fully understanding severity, causes and consequences of the problem; limited utilization and trust in health interventions; high workload, and health worker turnover and attrition; and high dependence on financial and technical support based on short-term emergency funding within a context of high demographic pressure.The study uncovered influencing factors of integrating acute malnutrition into the national health system and their complex dynamics and relationships. It elicited the need for goal-oriented strategies and alignment of health actors to achieve sustainability, and systems thinking to understand pathways that foster integration. We recommend that context-specific learning of integrating acute malnutrition may expand to include causal modelling and scenario testing to inform strategy

    To evaluate the influence of dental visiting patterns on the dental status and Oral Health-related Quality of Life (OHQoL) of patients visiting the University Clinic of Salamanca (Spain). This cross-sectional study consisted of a clinical oral examination and a questionnaire-based interviewin a consecutive sample of patients seeking a dental examination. Patients were classified as problem-based dental attendees(PB) and regular dental attendees(RB). Clinical and OHQoL(OHIP-14 & OIDP)data were compared betweengroups. Pair-wise comparisons were performed and a Logistic Regression Model was fitted for predicting the Odds Ratio (OR) of being a PB patient. The sample was composed of 255 patients aged 18 to 87 years (mean age: 63.1 ± 12.7; women: 51.8%). The PB patients had a poorer dental status (i.e. caries, periodontal and prosthetic needs), brushed their teethless,and were significantly more impaired in their OHQoL according to both instruments.The logistic regression coefficients demonstrated that on average the OR of being a PB patient was high in this dental patient sample, but this OR increased significantly if the patient was a male (OR= 1.1-5.0) or referred pain-related impacts according to the OHIP and, additionally, the OR decreased significantly as a function of the number of healthy fillings and the number of sextants coded as CPI=0. Regular dental check-ups are associated with better dental status and a better OHQoL after controlling for potentially related confounding factors.

    No clear evidence is available in the literature regarding the acute effect of different styles of music on cardiac autonomic control. The present study aimed to evaluate the acute effects of classical baroque and heavy metal musical auditory stimulation on Heart Rate Variability (HRV) in healthy men. In this study, HRV was analyzed regarding time (SDNN, RMSSD, NN50, and pNN50) and frequency domain (LF, HF, and LF / HF) in 12 healthy men. HRV was recorded at seated rest for 10 minutes. Subsequently, the participants were exposed to classical baroque or heavy metal music for five minutes through an earphone at seated rest. After exposure to the first song, they remained at rest for five minutes and they were again exposed to classical baroque or heavy metal music. The music sequence was random for each individual. Standard statistical methods were used for calculation of means and standard deviations. Besides, ANOVA and Friedman test were used for parametric and non-parametric distributions, respectively. While listening to heavy metal music, SDNN was reduced compared to the baseline (P = 0.023). In addition, the LF index (ms(2) and nu) was reduced during exposure to both heavy metal and classical baroque musical auditory stimulation compared to the control condition (P = 0.010 and P = 0.048, respectively). However, the HF index (ms(2)) was reduced only during auditory stimulation with music heavy metal (P = 0.01). The LF/HF ratio on the other hand decreased during auditory stimulation with classical baroque music (P = 0.019). Acute auditory stimulation with the selected heavy metal musical auditory stimulation decreased the sympathetic and parasympathetic modulation on the heart, while exposure to a selected classical baroque music reduced sympathetic regulation on the heart.

    There is bidirectional communication between the immune system and the gut microbiome, however the precise mechanisms regulating this crosstalk are not well understood. Microbial-associated molecular patterns (MAMPs) within the gut, including lipopolysaccharide (LPS) that produces a quick and robust activation of the immune system, may be one way by which these interactions occur. Endogenous levels of LPS in the gut are low enough that they do not usually cause disease, although, in times of increased LPS loads, they may be capable of increasing vulnerability of the gut to pathogenic bacteria. Furthermore, chronic, low-grade inflammation can have lasting effects on the gut, but the effects of acute inflammation on gut communities have not been thoroughly assessed. In this study, we first investigated whether a single modest dose of LPS administered to adult male and female Siberian hamsters (Phodopus sungorus) activated the immune system by measuring levels of circulating cortisol and the proinflammatory cytokine TNF-α in the liver compared with saline-treated animals. We then investigated whether this same acute dose of LPS altered the microbiome 48 h after treatment. We found that, although LPS increased cortisol and liver cytokine levels, and produced changes in food intake and body mass in both sexes, immunological changes were independent of gut dysbiosis 48 h after LPS injection. These data suggest that an acute immune activation may not be capable of altering the gut microbiome in healthy individuals. It is likely, however, that this type of immune challenge may have other physiological impacts on the gut's vulnerability, and future studies will investigate these relationships further. © 2018 The Authors.

    The motivational climate created by the athletic trainer in rehabilitation may be critical in influencing athletes' intrinsic motivation and other psychosocial outcomes in the rehabilitation and the recovery process. The purpose of this study was to examine intercollegiate athletes' perceptions of the motivational climate in the rehabilitation setting. Specifically, examining if perceptions of the motivational climate can predict athletes' levels of intrinsic motivation with rehabilitation as well as the relationship between perceptions of the motivational climate and athlete demographics (gender, starter status, athletic trainer gender, etc). Cross-sectional, descriptive research. College sport team and athletic training center. NCAA Division II intercollegiate athletes from one institution (n = 187; 125 male, 62 female). Paper-based survey measuring: mastery and performance perceptions of the motivational climate in rehabilitation, athletes' goal orientation in sport, athletes' levels of motivation in rehabilitation. Perceptions of a performance climate was positively related to intrinsic motivation effort-improvement (effect size=25.34%). Perceptions of a mastery climate were positively related to interest-enjoyment and perceived competence and negatively related to tension-pressure (effect size=39.03%). In general, female athletes, as well as athletes with a female athletic trainer, had significantly higher perceptions of mastery motivational climate effort-improvement compared to male athletes and athletes with male athletic trainers. While male athletes and athletes with male athletic trainers had higher perceptions of intra-team member rivalry in rehabilitation. The athlete's gender and goal orientation, as well as the gender of the athletic trainer creating the motivational climate, can influence whether the environment is perceived as more mastery or performance. The recovering athletes' perceptions of the climate in rehabilitation can, in turn, affect

    Full Text Available Fear learning and regulation is a prominent model for describing the pathogenesis of anxiety disorders and stress-related psychopathology. Fear expression can be modulated using a number of regulatory strategies, including extinction, cognitive emotion regulation, avoidance strategies and reconsolidation. In this review, we examine research investigating the effects of acute stress and stress hormones on these regulatory techniques. We focus on what is known about the impact of stress on the ability to flexibly regulate fear responses that are acquired through Pavlovian fear conditioning. Our primary aim is to explore the impact of stress on fear regulation in humans. Given this, we focus on techniques where stress has been linked to alterations of fear regulation in humans (extinction and emotion regulation, and briefly discuss other techniques (avoidance and reconsolidation where the impact of stress or stress hormones have been mainly explored in animal models. These investigations reveal that acute stress may impair the persistent inhibition of fear, presumably by altering prefrontal cortex function. Characterizing the effects of stress on fear regulation is critical for understanding the boundaries within which existing regulation strategies are viable in everyday life and can better inform treatment options for those who suffer from anxiety and stress-related psychopathology.

    The aim of this study was to utilize static test for examining the acute toxicity of two essential elements, Cu and Zn, to a native fish, Capoeta fusca, by static bioassay. The acute toxicity of two heavy metals to C. fusca was determined in the soft, hard and very hard water (40, 150 and 380 mg/L as CaCO(3)). Results showed that toxicity of Cu and Zn decreased with increasing water hardness, so that water hardness had a significant effect on Cu and Zn toxicity on fish. Copper and Zn were more toxic in the soft water than in the hard water. The 96-hour lethal concentration for 50% (LC(50)) values for C. fusca were lower in the soft water compared with the hard and very hard water. The 96-hour LC(50) for Cu at the soft, hard and very hard water was found to be 1.1, 5.4 and 7.5 mg/L, respectively, while the 96-hour LC(50) for Zn at the soft, hard and very hard water was found to be 13.7, 74.4 and 102.9 mg/L, respectively.

    Full Text Available The effects of acute exposure to high glucose levels as experienced by glomerular mesangial cells in postprandial conditions and states such as in prediabetes were investigated using proteomic methods. Two-dimensional gel electrophoresis and matrix assisted laser desorption ionization time of flight mass spectrometry methods were used to identify protein expression patterns in immortalized rat mesangial cells altered by 2 h high glucose (HG growth conditions as compared to isoosmotic/normal glucose control (NG⁎ conditions. Unique protein expression changes at 2 h HG treatment were measured for 51 protein spots. These proteins could be broadly grouped into two categories: (1 proteins involved in cell survival/cell signaling and (2 proteins involved in stress response. Immunoblot experiments for a protein belonging to both categories, prohibitin (PHB, supported a trend for increased total expression as well as significant increases in an acidic PHB isoform. Additional studies confirmed the regulation of proteasomal subunit alpha-type 2 and the endoplasmic reticulum chaperone and oxidoreductase PDI (protein disulfide isomerase, suggesting altered ER protein folding capacity and proteasomal function in response to acute HG. We conclude that short term high glucose induces subtle changes in protein abundances suggesting posttranslational modifications and regulation of pathways involved in proteostasis.

    Full Text Available An implementation of series of preclinical studies of the copper nanoparticle-ceftriaxone conjugate as a new medication with a broad spectrum of antimicrobial action for treatment of infections, particularly caused by resistant strains, is of great importance nowadays. The aim of current research was to determinate effect of studied substance on cardiovascular function in animals when administered intravenously in an acute experiment. Methods and results. The study was carried out on 8 Chinchilla rabbits with monitoring of systemic and cardiac hemodynamic indices with ‘Hewlett Packard’ Hp Viridia Component Monitoring System. It was shown that the copper nanoparticle-ceftriaxone conjugate at doses of 10–200 mg/kg did not have a negative impact on the heart rate, maximum left ventricular pressure, systolic, diastolic blood pressure, the pulse pressure, and the mean arterial pressure. Conclusion. These findings attest to the fact that the copper nanoparticle-ceftriaxone conjugate may be considered a biosafe substance in the terms of an influence on systemic and cardiac hemodynamic indices when administered intravenously to rabbits in an acute experiment.

    Full Text Available Acute kidney injury (AKI is associated with significant morbidity and mortality in hypertensive surroundings. We investigated superoxide radical molecules influence on systemic haemodynamic and kidney function in spontaneously hypertensive rats (SHR with induced postischemic AKI. Experiment was performed in anesthetized adult male SHR. The right kidney was removed, and left renal artery was subjected to ischemia by clamping for 40 minutes. The treated group received synthetic superoxide dismutase mimetic TEMPOL in the femoral vein 5 minutes before, during, and 175 minutes after the period of reperfusion, while the control AKI group received the vehicle via the same route. All parameters were measured 24 h after renal reperfusion. TEMPOL treatment significantly decreased mean arterial pressure and total peripheral resistance P<0.05 compared to AKI control. It also increased cardiac output and catalase activity P<0.05. Lipid peroxidation and renal vascular resistance were decreased in TEMPOL P<0.05. Plasma creatinine and kidney morphological parameters were unchanged among TEMPOL treated and control groups. Our study shows that superoxide radicals participate in haemodynamic control, but acute superoxide scavenging is ineffective in glomerular and tubular improvement, probably due to hypertension-induced strong endothelial dysfunction which neutralizes beneficial effects of O2− scavenging.

    This study aimed to describe the acute impact of extended interval training (EIT) on physiological and thermoregulatory levels, as well as to determine the influence of athletic performance and age effect on the aforementioned response in endurance runners. Thirty-one experienced recreational male endurance runners voluntarily participated in this study. Subjects performed EIT on an outdoor running track, which consisted of 12 runs of 400 m. The rate of perceived exertion, physiological response through the peak and recovery heart rate, blood lactate, and thermoregulatory response through tympanic temperature, were controlled. A repeated measures analysis revealed significant differences throughout EIT in examined variables. Cluster analysis grouped according to the average performance in 400 m runs led to distinguish between athletes with a higher and lower sports level. Cluster analysis was also performed according to age, obtaining an older group and a younger group. The one-way analysis of variance between groups revealed no significant differences (p≥0.05) in the response to EIT. The results provide a detailed description of physiological and thermoregulatory responses to EIT in experienced endurance runners. This allows a better understanding of the impact of a common training stimulus on the physiological level inducing greater accuracy in the training prescription. Moreover, despite the differences in athletic performance or age, the acute physiological and thermoregulatory responses in endurance runners were similar, as long as EIT was performed at similar relative intensity.

    Full Text Available This study extended the ordered protection motivation framework to determine whether exposure and attention to antiobesity media content increases people’s appraisals of threat and their ability to cope with it. It also assesses whether these cognitive processes, in turn, affected people’s intention to abide by the practices recommended to prevent obesity. The results of a national online survey using a nonprobability sample indicate that attention to mediated obesity and related information significantly increased people’s intention to exercise as well as their overall coping appraisals (the perceived effectiveness of the recommended behaviors and their ability to perform them. Likewise, increased threat and coping appraisals were both found to significantly influence people’s intention to exercise and diet. Coping (rather than threat appraisals more strongly predicted behavioral intent. Following the attitude-behavior literature, behavioral intention was used as the most proximate predictor of actual behavior (i.e., stronger intentions increase the likelihood of behavior change.

    Full Text Available B-cell acute lymphoblastic leukemia (B-ALL is a serious public health problem in the pediatric population worldwide, contributing to 85% of deaths from childhood cancers. Understanding the biology of the disease is crucial for its clinical management and the development of therapeutic strategies. In line with that observed in other malignancies, chronic inflammation may contribute to a tumor microenvironment resulting in the damage of normal processes, concomitant to development and maintenance of neoplastic cells. We report here that hematopoietic cells from bone marrow B-ALL have the ability to produce proinflammatory and growth factors, including TNFα, IL-1β, IL-12, and GM-CSF that stimulate proliferation and differentiation of normal stem and progenitor cells. Our findings suggest an apparently distinct CD13+CD33+ population of leukemic cells contributing to a proinflammatory microenvironment that may be detrimental to long-term normal hematopoiesis within B-ALL bone marrow.

    The short-T2 appearance of acute hematomas has been previously explained solely by water diffusing in and out of deoxyhemoglobin-containing red cells. According to this theory, the maximum effect occurs at a 50% hematocrit and should be absent at 100% hematocrit. This theory fails to take clot retraction per se into account. The authors have confirmed that the shortest T2 of heparinized blood (deoxyhemoglobin form by Raman spectroscopy) occurs at 50% hematocrit. Retraction of nonparamagnetic plasma and oxyhemogloblin clots over 24 hours shortens T2 by 10%-40% at 90 MHz, depending on the platelet concentration. The additional T2 shortening observed after formation of deoxyhemoglobin is thus primarily due to clot retraction

    Full Text Available Chemotherapeutic agents used in patients with cancer cause to generate the enormous amounts of free radicals associated with cell injury. In this study we assess the effects of chemotherapy regimen on oxidant/antioxidant status in patients with acute myeloid leukemia (AML. 38 newly diagnosed patients with acute myeloid leukemia were recruited in this study. All patients received cytarabine and daunorubicin as chemotherapy regimen. Plasma levels of malondialdehyde (MDA, total antioxidant status (TAS, and the levels of erythrocyte activity of superoxide dismutase (SOD and glutathione peroxidase (GPx were determined before chemotherapy and 14 days after chemotherapy with cytarabine and daunorubicin. Plasma MDA concentrations increased significantly (from 2.68±0.89 nmol/L to 3.14±1.29 nmol/L during the 14days post-chemotherapy period (P=0.04. Plasma TAS concentrations changed with chemotherapy from 1.09±0.15 mmol/L to 1.02±0.14 mmol/L with P=0.005. Erythrocyte SOD and GPX activity decreased overtime from 1157.24±543.61 U/g Hb to 984.01±419.09 U/g Hb (P=0.04 and 46.96±13.70 U/g Hb to 41.40±6.44 U/g Hb (P=0.02 respectively. We report here that there is an increase in malondialdehyde levels and a decrease in the levels of antioxidant enzymes and total antioxidant status. This suggests that chemotherapy causes these changes as a result of enormous production of reactive oxygen species in the patients with AML. Antioxidant supplementation must be approached with caution because of the probability of reduction the therapeutic efficacy of these cytotoxic drugs.

  1. The influence of acute stress on attention mechanisms and its electrophysiological correlates

    Full Text Available For the selection of relevant information out of a continuous stream of information, which is a common definition of attention, two core mechanisms are assumed: a competition-based comparison of the neuronal activity in sensory areas and the top-down modulation of this competition by frontal executive control functions. Those control functions are thought to bias the processing of information towards the intended goals. Acute stress is thought to impair these frontal functions through the release of cortisol.In the present study, subjects had to detect a luminance change of a stimulus and ignore more salient but task irrelevant orientation changes. Before the execution of this task, subjects underwent a socially evaluated cold pressor test (SECPT or a non-stressful control situation. The SECPT revealed reliable stress response with a significant increase of cortisol and alpha-amylase. Stressed subjects showed higher error rates than controls, particularly in conditions which require top-down control processing to bias the less salient target feature against the more salient and spatially separated distracter.By means of the EEG, subjects who got stressed showed a reduced allocation to the relevant luminance change apparent in a modulation of the N1pc. The following N2pc, which reflects a re-allocation of attentional resources, supports the error pattern. There was only an N2pc in conditions, which required to bias the less salient luminance change. Moreover, this N2pc was decreased as a consequence of the induced stress. These results allow the conclusion that acute stress impairs the intention-based attentional allocation and enhances the stimulus-driven selection, leading to a strong distractibility during attentional information selection.

    The Patient Activation Measure (PAM) is a validated assessment tool that evaluates how engaged patients are in their own health care. The more engaged or "activated" patients are, the higher the score and the more likely they are to adhere to medical therapy and make healthy lifestyle choices. Little is known regarding patient activation in patients after an acute myocardial infarction. From March 2016 to December 2016, we administered PAM surveys to patients after myocardial infarction at the time of a clinic visit scheduled within 10 days of hospital discharge. Demographic and outcome data were collected. The primary outcome was defined as a composite end point of major medication errors, emergency department visits, and/or unplanned readmission. The secondary outcome was continued tobacco use after discharge. A total of 93 patients were enrolled and 39 (42%) were positive for the primary outcome. PAM scores ranged from 40.9 to 100 (median 62.6, interquartile range 56.0 to 72.1). In multivariable analysis, adjusting for age, gender, and burden of co-morbidities, patients with lower PAM scores were more likely to have the primary outcome (odds ratio 1.063, 95% confidence interval 1.020 to 1.109, p = 0.0041). Patients with lower PAM scores also were more likely to continue to use tobacco after discharge (odds ratio 1.060, 95% confidence interval 1.005 to 1.118, p = 0.0325). In conclusion, we found an association between lower PAM scores and subsequent adverse clinical outcomes, including unplanned readmissions. Further investigation into the potential effect of education and coaching interventions in patients with low PAM scores after acute myocardial infarction is warranted. Copyright © 2017 Elsevier Inc.

    The stress-induced release of glucocorticoids has been demonstrated to influence hippocampal functions via the modulation of specific receptors. At the behavioral level stress is known to influence hippocampus dependent long-term memory. In recent years, studies have consistently associated the hippocampus with the non-mnemonic perception of scenes, while adjacent regions in the medial temporal lobe were associated with the perception of objects, and faces. So far it is not known whether and how stress influences non-mnemonic perceptual processes. In a behavioral study, fifty male participants were subjected either to the stressful socially evaluated cold-pressor test or to a non-stressful control procedure, before they completed a visual discrimination task, comprising scenes and faces. The complexity of the face and scene stimuli was manipulated in easy and difficult conditions. A significant three way interaction between stress, stimulus type and complexity was found. Stressed participants tended to commit more errors in the complex scenes condition. For complex faces a descriptive tendency in the opposite direction (fewer errors under stress) was observed. As a result the difference between the number of errors for scenes and errors for faces was significantly larger in the stress group. These results indicate that, beyond the effects of stress on long-term memory, stress influences the discrimination of spatial information, especially when the perception is characterized by a high complexity.

    This study presents British farmers' perception of, and barriers to, implementing Salmonella control on pig farms. Four farms that had implemented interventions and their 33 close contacts (known to the intervention farmers) took part in interviews before (phase 1) and after (phase 2) intervention trials to assess the difference in perception over time. Their results were compared against those from nine randomly selected control farms. The hypothesis was that farms implementing interventions whether or not successful, would influence their close contacts' opinion over time. Based on a 'pathway to disease control' model, three intrinsic factors known to influence motivation - attitudes, social norms and self-efficacy - were evaluated. Farmers mentioned that successful interventions on a farm would attract their attention. The use of an appropriate communication strategy is therefore recommended to stimulate farmers' intent to implement control measures. Both before and after the intervention trials, all farmers had a positive attitude towards Salmonella control and felt that their peers and authorities were supportive of controlling Salmonella on farms. In phase 2, however, farmers were more likely to want to share the burden of control with other stakeholders along the food chain and their belief in self-efficacy had weakened. Whilst social norms were not associated with an intention to take action on control, a positive attitude towards Salmonella control and a belief in self-efficacy were more likely to result in an intent to control. In phase 2, farmers with an intent to implement an intervention appeared to have a greater, but not significant positive belief in self-efficacy (p=0.108). This study confirmed that farmers recognised their responsibility for controlling Salmonella in pork - even though their confidence in their ability to control Salmonella decreased over time - and believed that responsibility should be shared with the rest of the production

Methylenetetrahydrofolate reductase (MTHFR is a key enzyme for MTX pharmacokinetics. Two single-nucleotide polymorphisms in MTHFR gene, C677T and A1298C, affecting MTHFR activity, have been widely studied as potential markers of MTX toxicity and/or outcome in pediatric ALL. In this review, we show that the majority of published reports do not find association or present opposite effect. Therefore, MTHFR C677T and A1298C polymorphisms do not seem to be good markers of MTX-related toxicity and/or outcome in pediatric ALL. The efforts should be focused on other genes, such as transporter genes or microRNA-related genes. Keywords: MTHFR, methotrexate, toxicity, outcome, C677T, A1298C

    We studied the effects of acute erythrocythemia on temperature regulation responses during exercise in the heat. In a double blind study, 6 subjects (Ss) received a 700-ml solution of autologous red blood cells at a 60% Hct, and 3 Ss (control) received a 700-ml saline solution. All Ss attempted a Heat Stress Test (HST) two weeks prior to and 48-h post-transfusion during summer months. After 30 min of rest in a 20 0 C antechamber, the HST consisted of a 120-min exposure (two repeats of 15-min rest and 45-min treadmill walk) in a 35 0 C, 45% rh environment while euhydrated. Maximal oxygen uptake (VO 2 max) and red cell volume (RCV, 51 Cr) were measured approximately 24 h before each HST. For experimental Ss, an increase in RCV (11%, P 2 max (11%, P < 0.05) was found following transfusion, whereas, differences were not observed in the control Ss. During the HSTs for experimental Ss, metabolic rate as well as steady state rectal and esophageal temperatures were similar, but heat storage tended (P = 0.13) to be lower post-transfusion. Steady state local arm (R + C) was reduced (P < 0.05) with no change in total body sweating rate or local arm evaporative heat loss post-transfusion. For control Ss, thermoregulatory responses were generally not altered post-transfusion. Erythrocythemia may improve steady state sensible heat exchange by allowing a greater volume of blood to be directed to the cutaneous vasculature

    The ability of leukemia cells to accumulate methotrexate polyglutamate (MTXPG) is an important determinant of the antileukemic effects of methotrexate (MTX). We measured in vivo MTXPG accumulation in leukemia cells from 101 children with acute lymphoblastic leukemia (ALL) and established that B-lineage ALL with either TEL-AML1 or E2A-PBX1 gene fusion, or T-lineage ALL, accumulates significantly lower MTXPG compared with B-lineage ALL without these genetic abnormalities or compared with hyperdiploid (fewer than 50 chromosomes) ALL. To elucidate mechanisms underlying these differences in MTXPG accumulation, we used oligonucleotide microarrays to analyze expression of 32 folate pathway genes in diagnostic leukemia cells from 197 children. This revealed ALL subtype–specific patterns of folate pathway gene expression that were significantly related to MTXPG accumulation. We found significantly lower expression of the reduced folate carrier (SLC19A1, an MTX uptake transporter) in E2A-PBX1 ALL, significantly higher expression of breast cancer resistance protein (ABCG2, an MTX efflux transporter) in TEL-AML1 ALL, and lower expression of FPGS (which catalyzes formation of MTXPG) in T-lineage ALL, consistent with lower MTXPG accumulation in these ALL subtypes. These findings reveal distinct mechanisms of subtype-specific differences in MTXPG accumulation and point to new strategies to overcome these potential causes of treatment failure in childhood ALL.

    AIM: The purpose of this study was to determine the incidence of secondary signs associated with ureteral stones on unenhanced helical computed tomography (CT) of patients with acute renal colic, and to correlate these with patient management and outcome. MATERIALS AND METHODS: One hundred and ten patients with ureterolithiasis were evaluated prospectively for the secondary signs of obstruction on unenhanced helical CT. Our attention was focused primarily on the presence or absence of seven secondary signs on unenhanced helical CT, including hydronephrosis, unilateral renal enlargement, perinephric oedema, unilateral absence of the white pyramid, hydroureter, periureteral oedema and lateroconal fascial thickening. RESULTS: Of the 110 patients, 91 (82.7%) had hydroureter, 88 (80%) had hydronephrosis, 65 (59%) had periureteric oedema and 63 (57.2%) had unilateral renal enlargement. Ninety stones passed spontaneously and 21 required intervention. CONCLUSION: Secondary signs of urinary tract obstruction are useful and supportive findings in interpretation of the CT examination. In our experience, the most reliable signs indicating ureteral obstruction are hydroureter, hydronephrosis, periureteral oedema and unilateral renal enlargement, respectively. In addition, stones larger than 6 mm, located within the proximal two thirds of the ureter, and seen associated with five or more the secondary signs of obstruction, are more likely to require endoscopic removal and/or lithotripsy.

    To assess the interactions between weather and the impact of each individual meteorological parameters in the incidence of acute myocardial infarctions (AMI) in Galicia. Retrospective study analyzing the number of AMI diagnosed and transferred to the hospital by the Emergencies Sanitary System of Galicia between 2002 and 2009. We included patients with clinical and ECG findings of AMI. The correlation between 10-minute meteorological variables (temperature, humidity, pressure, accumulated rainfall and wind speed) recorded by MeteoGalicia and the incidence of AMI was assessed. A total of 4,717 AMI were registered (72.8% men, 27.2% women). No seasonal variations were found. No significant correlations were detected with regard to average daily temperature (P=.683) or wind speed (P=.895). Correlation between atmospheric pressure and incidence of AMI was significant (P<.005), as well as with the daily relative humidity average (P=.005). Our study showed a statistical significant association with atmospheric pressure and with the daily relative humidity average. Since the local conditions of weather are widely variable, future studies should establish the relationship between weather patterns (including combinations of meteorological parameters), rather than seasonal variations, and the incidence of AMI.

    The acute effects of stretching on peak force (Fpeak), percent voluntary activation (%VA), electromyographic (EMG) amplitude, maximum range of motion (MROM), peak passive torque, the passive resistance to stretch, and the percentage of ROM at EMG onset (%EMGonset) were examined in 18 young and 19 old men. Participants performed a MROM assessment and a maximal voluntary contraction of the plantarflexors before and immediately after 20 min of passive stretching. Fpeak (-11 %), %VA (-6 %), and MG EMG amplitude (-9 %) decreased after stretching in the young, but not the old (P > 0.05). Changes in Fpeak were related to reductions in all muscle activation variables (r = 0.56-0.75), but unrelated to changes in the passive resistance to stretch (P ≥ 0.24). Both groups experienced increases in MROM and peak passive torque and decreases in the passive resistance to stretch. However, the old men experienced greater changes in MROM (P stretching for both groups (P = 0.213), but occurred earlier in the old (P = 0.06). The stretching-induced impairments in strength and activation in the young but not the old men may suggest that the neural impairments following stretching are gamma-loop-mediated. In addition, the augmented changes in MROM and passive torque and the lack of change in %EMGonset for the old men may be a result of age-related changes in muscle-tendon behavior.

    The concept of motivation is used in many different disciplines to analyze the ‘what and why’ (Deci & Ryan, 2000) of human action. A vast body of literature exists on the relationship of motivation and performance in professional work and organization settings (e.g. Osterloh, Frey & Homberger, 2011; Gagné & Deci, 2005). Motivation is widely acknowledged to enhance performance and efficiency of staff (Ryan & Deci, 2000). Beyond work settings motivation may influence performance in academic set...

    In acute psychiatric services, rapid and accurate detection of psychoactive substance intake may be required for appropriate diagnosis and intervention. The aim of this study was to investigate the relationship between (a) drug influence as assessed by physicians and (b) blood drug concentrations among patients admitted to acute psychiatric wards. We also explored the possible effects of age, sex, and psychotic symptoms on physician's assessment of drug influence. In a cross-sectional study, the sample comprised 271 consecutive admissions from 2 acute psychiatric wards. At admission, the physician on call performed an overall judgment of drug influence. Psychotic symptoms were assessed with the positive subscale of the Positive and Negative Syndrome Scale. Blood samples were screened for a wide range of psychoactive substances, and quantitative results were used to calculate blood drug concentration scores. Patients were judged as being under the influence of drugs and/or alcohol in 28% of the 271 admissions. Psychoactive substances were detected in 56% of the blood samples. Altogether, 15 different substances were found; up to 8 substances were found in samples from 1 patient. Markedly elevated blood drug concentration scores were estimated for 15% of the patients. Physician's assessment was positively related to the blood drug concentration scores (r = 0.52; P < 0.001), to symptoms of excitement, and to the detection of alcohol, cannabis, and amphetamines. The study demonstrates the major impact of alcohol and drugs in acute psychiatric settings and illustrates the challenging nature of the initial clinical assessment.

    Forty-eight-hour acute toxicity tests were performed to determine the influence of acclimation temperature (5, 15, and 20 C) and exposure temperature (5, 15, and 20 C) on the toxicity of cadmium to the freshwater gastropod Potamopyrgus antipodarum. Mortality varied with cadmium concentration and treatment conditions, but did not conform to conventional sigmoid concentration-response relationships. Because the shapes of the concentration-response curves were treatment dependent, a nontraditional approach for data analysis was employed. Regardless of acclimation temperature, mortality increased with increasing exposure temperature, and at all exposure temperatures snails acclimated at 15 C were most susceptible to cadmium toxicity. Estimated LC50 values were within 1 to 4 mg Cd/L. Although the shapes of the concentration-response curves were different for each treatment, the slopes were generally quite steep, indicating a uniform response for the whole population. At a given Cd concentration, acclimation temperature and exposure temperature accounted for 57 and 40%, respectively, of the variation in mortality, and LC50s changed by a factor of four. The results indicate that changes in environmental variables can alter both the degree of response and the response distribution of a population, and that past as well as prevailing environmental conditions can influence organismic responses to toxicants.

    There is a correlation between both serum hemoglobin (HGB) and hematocrit (HCT) and attenuation values of vessels in noncontrast-enhanced computed tomography (NECT), which could influence calculated perfusion maps in CT perfusion. We retrospectively included 45 patients, who presented with acute new neurological symptoms and underwent NECT and CT perfusion (128-row multi detector scanner, coverage: 6.9 cm craniocaudally; 80 kV; 200 mAs; temporal resolution: 2 seconds using 40 mL Ultravist 370 at a flow rate of 5 mL/s) on admission and a follow-up MRI within 1 week of admission. Hematocrit, HGB, and attenuation values did not differ between patients with stroke and controls. A statistically significant correlation was found between HCT and HGB and attenuation values in the internal carotid artery or middle cerebral artery on NECT (P Hematocrit and HGB do not influence calculated perfusion maps. There is no need for HCT/HGB-adjusted cerebral blood volume thresholds in stroke patients.

    Purpose We sought to determine whether cranial radiotherapy (CRT) is necessary to prevent relapse in any subgroup of children with acute lymphoblastic leukemia (ALL). Patients and Methods We obtained aggregate data on relapse and survival outcomes for 16,623 patients age 1 to 18 years old with newly diagnosed ALL treated between 1996 and 2007 by 10 cooperative study groups from around the world. The proportion of patients eligible for prophylactic CRT varied from 0% to 33% by trial and was not related to the proportion eligible for allogeneic stem-cell transplantation in first complete remission. Using a random effects model, with CRT as a dichotomous covariate, we performed a single-arm meta-analysis to compare event-free survival and cumulative incidence of isolated or any CNS relapse and isolated bone marrow relapse in high-risk subgroups of patients who either did or did not receive CRT. Results Although there was significant heterogeneity in all outcome end points according to trial, CRT was associated with a reduced risk of relapse only in the small subgroup of patients with overt CNS disease at diagnosis, who had a significantly lower risk of isolated CNS relapse (4% with CRT v 17% without CRT; P = .02) and a trend toward lower risk of any CNS relapse (7% with CRT v 17% without CRT; P = .09). However, this group had a relatively high rate of events regardless of whether or not they received CRT (32% [95% CI, 26% to 39%] v 34% [95% CI, 19% to 54%]; P = .8). Conclusion CRT does not have an impact on the risk of relapse in children with ALL treated on contemporary protocols. PMID:26755523

    Objective To evaluate the impact of the 2006 Massachusetts (MA) health reform on disparities in the management of acute cholecystitis (AC). Summary Background Data Immediate cholecystectomy has been shown to be the optimal treatment for AC, yet variation in care persists depending upon insurance status and patient race. How increased insurance coverage impacts these disparities in surgical care is not known. Methods A cohort study of patients admitted with AC in MA and three control states from 2001 through 2009 was performed using the Hospital Cost and Utilization Project State Inpatient Databases. We examined all non-elderly White, black, or Latino patients by insurance type and patient race, evaluating changes in the probability of undergoing immediate cholecystectomy and disparities in receiving immediate cholecystectomy before and after Massachusetts health reform. Results Data from 141,344 patients hospitalized for AC were analyzed. Prior to the 2006 reform, government-subsidized/self-pay (GS/SP) patients had a 6.6 to 9.9 percentage-point lower (p<0.001) probability of immediate cholecystectomy in both MA control states. The MA insurance expansion was independently associated with a 2.5 percentage-point increased probability of immediate cholecystectomy for all GS/SP patients in MA (p=0.049) and a 5.0 percentage-point increased probability (p=0.011) for non-white, GS/SP patients compared to control states. Racial disparities in the probability of immediate cholecystectomy seen prior to health care reform were no longer statistically significant after reform in MA while persisting in control states. Conclusions The MA health reform was associated with increased probability of undergoing immediate cholecystectomy for AC and reduced disparities in undergoing cholecystectomy by insurance status and patient race.

    Because consumption of processed foods has increased in the last decades and so far its potential influence on emotionality and susceptibility to stress is unknown, we studied the influence of different fatty acids (FA) on behavioral and biochemical parameters after acute restrain stress (AS) exposure. Two sequential generations of female rats were supplemented with soybean oil (control group; C-SO), fish oil (FO) and hydrogenated vegetable fat (HVF) from pregnancy and during lactation. At 41days of age, half the animals of each supplemented group were exposed to AS and observed in open field and elevated plus maze task, followed by euthanasia for biochemical assessments. The HVF-supplemented group showed higher anxiety-like symptoms per se, while the C-SO and FO groups did not show these behaviors. Among groups exposed to AS, HVF showed locomotor restlessness in the open field, while both C-SO and HVF groups showed anxiety-like symptoms in the elevated plus maze, but this was not observed in the FO group. Biochemical evaluations showed higher lipoperoxidation levels and lower cell viability in cortex in the HVF group. In addition, HVF-treated rats showed reduced catalase activity in striatum and hippocampus, as well as increased generation of reactive species in striatum, while FO was associated with increased cell viability in the hippocampus. Among groups exposed to AS, HVF increased reactive species generation in the brain, decreased cell viability in the cortex and striatum, and decreased catalase activity in the striatum and hippocampus. Taken together, our findings show that the type of FA provided during development and growth over two generations is able to modify the brain oxidative status, which was particularly adversely affected by trans fat. In addition, the harmful influence of chronic consumption of trans fats as observed in this study can enhance emotionality and anxiety parameters resulting from stressful situations of everyday life, which can

    Full Text Available Objective To evaluate the influence of cardiac insufficiency on contrast-induced acute kidney injury (CIAKI after percutaneous coronary intervention (PCI in patients with diabetes mellitus (DM complicated with mild to moderate renal insufficiency (MMRI. Methods From Dec. 2008 to Oct. 2011, 2998 patients, with type 2 DM and concomitant chronic kidney diseases (CKD from 53 hospitals in China, were enrolled in the present study. Out of them, 2533 patients showed normal cardiac function (NYHA=1 and 465 patients suffered from cardiac insufficiency (NYHA>1. The demographic characteristics, preoperative renal function and postoperative incidence of CIAKI in the two groups were monitored. Results No significant difference was found between two groups (P>0.05 in preoperative baseline data (age, sex, high risk factors, etc.. The incidence of CIAKI was significantly higher in NYHA>1 group than in NYHA=1 group (4.7% vs2.8%, P=0.03. During a 30 day follow-up, the incidence of all-cause mortality was not significantly different between two groups (P>0.05. Multiple factors analysis found that rosuvastatin was the protective agent for CIAKI, and acute coronary syndrome, cardiac insufficiency, anemia and renal insufficiency were the risk factors for CIAKI. Conclusion For PCI, the risk of postoperative incidence of CIAKI is higher in patients with preoperative cardiac insufficiency than in those with normal cardiac function. The incidence of CIAKI may be reduced obviously by meticulous preoperative assessment of heart function in high-risk patients, giving effective treatment and performing PCI after cardiac function is improved.

    Comprehensive discharge planning is important for successful transitions from hospital to home after stroke. The aim of this study was to describe the quality of discharge planning received by patients discharged home from acute care, identify factors associated with a positive discharge experience, and assess the influence of discharge quality on outcomes. Patients discharged to the community and registered in the Australian Stroke Clinical Registry in 2014 were invited to participate. Patient-perceived discharge quality was evaluated using the Prescriptions, Ready to re-enter community, Education, Placement, Assurance of safety, Realistic expectations, Empowerment, Directed to appropriate services questionnaire (recall at 3-9 months). Factors associated with higher discharge quality scores were identified and associations between quality scores of more than 80% and outcomes were investigated using multivariable, multilevel regression analyses. There were 200 of 434 eligible registrants who responded; responders and nonresponders were similar with respect to age, sex, and type of stroke. The average overall quality score was 73% (standard deviation: 21). However, only 18% received all aspects of discharge care planning. Quality scores of more than 80% were independently associated with receiving hospital specific information (odds ratio: 5.7, 95% confidence interval [CI]: 2.7, 12.4), and referral to a local support group (odds ratio: 2.5, 95% CI: 1.1, 5.9). Discharge quality scores of more than 80% were associated with higher European Quality of Life-5 Dimensions EQ-5D scores (coefficient: .1, 95% CI: .04, .2) and a reduction in the rate of unmet needs reported at 3-9 months postdischarge (incidence rate ratio: .5, 95% CI: .3, .7). We provide new information on the quality of discharge planning from acute care after stroke. Aspects of discharge planning that correlate with quality of care may reduce unmet needs and improve quality of life outcomes. Copyright

    Full Text Available Background: Neurological deterioration in acute spontaneous intra cerebral hemorrhage (ICH may depend on hematoma volume, electrolyte imbalances, hydration status and other physiological parameters. Plasma osmolality is a marker of hydration. This study has examined the relationship of plasma osmolality with hematoma volume and clinical outcome. Materials and Methods: This is a prospective observational study included 75 patients with non-traumatic acute spontaneous ICH. Plasma osmolality, hematoma volume and clinical outcome in National Institute Health stroke scale (NIHSS were measured on admission and on day 7 after treatment. Mean plasma osmolality was compared between those who died before day 7 and those who died after day 7. Plasma osmolality was also compared between patients with NIHSS score >20 and patients with NIHSS score ≤20. Paired t test, Pearson correlation coefficient and independent sample t test were done using SPSS software (version 17 for Windows. Result: There is no significant correlation between hematoma volume and plasma osmolality. Higher admission plasma osmolality was associated with early death [312.0 (±16.0 mOsm/kg for those who died before day 7 versus 297.0 (±14.7 mOsm/kg for those who died after day 7, P value =0.031]. Higher admission plasma osmolality was associated with very severe stroke [311.5 (±14.1 mOsm/Kg for patients with NIHSS score >20 versus 293.6 (±11.3 mOsm/kg for patients with NIHSS score ≤20, P value =0.000. Conclusion: High plasma osmolality is a predictor of early mortality. Hematoma volume is not influenced by plasma osmolality.

    We investigated the effect of a previous bout of intense exercise on exogenous spatial attention. In Experiment 1, a group of participants performed an exogenous spatial task at rest (without prior effort), immediately after intense exercise, and after recovering from an intense exercise. The analyses revealed that the typical "facilitation effect" (i.e., faster reaction times on cued than on uncued trials) immediately after exercise was positively correlated with participants' fitness level. In Experiment 2, a high-fit and a low-fit group performed the same task at rest (without prior effort) and immediately after an intense exercise. Results revealed that, after the bout of exercise, only low-fit participants showed reduced attentional effects compared to the rest condition. We argue that the normal functioning of exogenous attention was influenced by intense effort, affecting low-fit participants to a larger extent than to high-fit participants. As a consequence, target processing was prioritized over irrelevant stimuli.

    Objective: To analyze the influence in anatomic variance of coronary artery on function of left and right ventricles after acute inferior myocardial infarction (AIMI) treated with percutaneous coronary intervention therapy (PCI). Methods: Forty-seven inferior AIMI patients were divided into 2 groups: 12 left dominant group [including equipollent case, i.e. inferior wall of left ventricle supplied by left circumflex coronary artery (LCX), right ventricle by right coronary artery (RCA)] and 35 right dominant group (both inferior wall and right ventricle were supplied by RCA). Equilibrium radionuclide angiocardiography (ERNA) and myocardial perfusion imaging (MPI) were used for comparing the influence between different coronary artery flow patterns on biventricular hemodynamics, blood supply and prognosis of PCI after 3 months. Results: Comparison of ventricular function in left and right dominant coronal artery type groups discharged 7- 10 d after PCI, there were differences in left ventricular ejection fraction (LVEF) [(63.03 ± 5.64)% vs (57.67 ± 7.35)%, P=0.012], peak ejection rate (PER) [(3.52 ± 0.66) end-diastolic volume (EDV)/s vs (2.93 ± 0.73) EDV/s, P =0.011], peak filling rate (PFR) [(2.71 ± 0.88) EDV/s vs (2.11 ± 0.45 ) EDV/s, P=0.004], left free-wall regional ejection fraction [(81.94 ± 20.75)% vs (67.25 ± 16.54)%, P = O.032], and right free-wall regional ejection fraction [(57.86 ± 11.77)% vs (67.83 ± 10.38)%, P=0.012], right ventricular ejection fraction (RVEF) [(37.89 ± 3.86)% vs (41.67 ± 4.81)%, P=0.09]. After 3 months,there was difference only in RVEF [(44.60 ± 5.29)% vs (48.00 ± 3.30)%, P=0.043], but no difference in myocardial perfusion of left ventricle (P=0.357). Conclusions: In acute stage of AIMI right dominant group, there was more severe injury of right ventricle, in convalescent stage most of the right ventricular function resumed. The sustained right ventricular function in part of the patients can be demonstrated by ERNA

    The potential influence of probiotic supplementation on cardiovascular health and stress responsivity remains largely unexplored. Some evidence suggests the possibility that probiotics may influence blood pressure. A separate body of research suggests that exaggerated cardiovascular reactions to acute psychological stress in the laboratory predict cardiovascular morbidity and mortality. The current investigation explored the effect of acute probiotic use on (1) resting cardiovascular measures in healthy young adults and (2) cardiovascular and psychological reactions to an acute psychological stressor in the laboratory. Participants (N = 105, M [SD] age = 20.17 [1.26], 84.8% white) completed a 2-week, double-blind, and placebo-controlled trial of a multispecies and multistrain probiotic. Exclusion criteria included previous probiotic use, diagnosed gastrointestinal disorder, and/or current antibiotic use. At visits 1 and 2, participants completed the Paced Auditory Serial Addition Test, a widely used psychological stress task. Participants were randomly assigned to a probiotic blend or matched placebo. Compared with placebo, 2-week probiotic supplementation did not affect resting measures of cardiovascular function, cardiovascular responses during or recovery from stress, or psychological reactions to acute psychological stress. Contrary to expectations, short-term use of a probiotic supplement in healthy participants did not influence measures of cardiovascular function or responsivity to psychological stress. Future research is needed to determine species- and strain-specific effects of probiotics in healthy participants with various degrees of stress responsiveness, as well as in diseased populations.

    Objective: To evaluate emergent angiography and interventional management in treating massive upper gastrointestinal (GI) arterial hemorrhage, and to discuss the factors influencing the angiographic bleeding signs and the interventional therapeutic results. Methods: The clinical data of 56 patients with massive upper GI arterial hemorrhage, who underwent diagnostic arteriography and interventional management with trans-catheter vasopressin infusion and embolization, were retrospectively analyzed. Systolic blood pressure of both pre-and post-interventional therapy was recorded and statistically analyzed. The arteriographic positive rates were separately calculated according to the catheter tip's location, being placed at the 2nd grade branch or at the 3 rd -4 th grade branch of the artery, and the relation of the positive rate with the tip's location was analyzed. A comparison of the hemostatic effect between trans-catheter vasopressin infusion and trans-catheter embolization was made. Results: The average systolic blood pressure of pre-and post-procedure was (93.14 ± 18.63) mmHg and (11.64 ± 13.61) mmHg respectively, with a significant difference (P = 0.023). The angiographic bleeding signs were demonstrated in 12 cases (21.4%) with the catheter's tip at the 2nd grade branch and in 56 cases (100%) with the catheter's tip at the 3 rd -4 th grade branch,the difference between the two was of statistically significance (P < 0.05). The technical success rate and the clinical hemostasis rate of via catheter vasopressin infusion was 80% (16 / 20) and 55% (11/20) respectively. Of nine re-bleeding cases, seven were successfully controlled with embolization therapy by using microcatheter and two had to receive surgery because of arterial rupture which was proved by angiography. The technical and the clinical rates of success for transcatheter embolization therapy were 93% (42 / 45) and 89% (40 / 45) respectively. Recurrence of bleeding was seen in two patients who got

    To explore the influence factors of salt-sensitive hypertension and to observe changes of blood pressures and urinary sodium and potassium excretion in response to acute oral saline loading among essential hypertensive patients in China. Essential hypertensive patients from Beijing Jinzhan second community were included in this study. Salt-sensitivity was determined via the improved Sullivan's acute oral saline loading and furosemide volume-depletion tests. Binary logistic regression analysis was applied to explore influence factors of salt-sensitive hypertension. Acute oral saline loading induced changes on blood pressures and urinary sodium and potassium excretion were observed. Sixty-three salt-sensitive hypertensive patients were classified out of a total of 342(18.4%) essential hypertensive patients. Salt-sensitive patients were elder than the non-salt-sensitive patients (P 0.05) , gender (OR = 0.728, 95%CI:0.374-1.415, P > 0.05) , total cholesterol level (OR = 1.168, 95%CI:0.882-1.547, P > 0.05) and 24-hour urinary sodium (OR = 0.998, 95%CI:0.995-1.002, P > 0.05) were not influencing factors of salt-sensitivity among essential hypertensive patients. Bivariate general linear models for repeated measures showed that there were significant statistical differences on blood pressures and urinary electrolytes concentrations between the beginning of trials, 2 hours after acute saline loading and 2 hours after furosemide volume-depletion(all P salt-sensitive patients than in non-salt-sensitive patients(all P 0.05). Age, gender, total cholesterol level and 24-hour urinary sodium are not influencing factors of salt-sensitivity among essential hypertensive patients in this study. Impaired pressure natriuresis during acute oral saline loading and furosemide volume-depletion tests is presented in salt-sensitive essential hypertensive patients.

    Drinking, abstinence, and academic motives have been previously linked with alcohol consumption in high school and college students; however, little research has examined the impact of such sources of motivations concurrently. Drawing from self-determination theory (SDT; Ryan & Deci, 2000), the current study tested the hypothesis that alcohol-related and academic motives would be associated with one another along internal vs. external focused dimensions. We also examined the relative influence of these motives on alcohol consumption. College students (N=226) completed self-report measures assessing drinking motives, abstinence motives, academic motives, and alcohol-related outcomes. Findings suggest that drinking motives are related to abstinence motives but not academic motives. Both forms of alcohol-related motives were related to alcohol use and consequences; no associations between academic motives and alcohol variables were observed. The lack of associations among academic motives, alcohol-related motives, and alcohol variables departs from previous findings suggesting that academic motives impact alcohol use. The current findings indicate a greater understanding of the interplay of motivational sets related to salient issues for youth, such as academics, is needed in order to expand intervention models for alcohol use in such populations.

    Due to the implementation of the diagnosis-related groups (DRG) system, the competitive pressure on German hospitals increased. In this context it has been shown that acute pain management offers economic benefits for hospitals. The aim of this study was to analyze the impact of the competitive situation, the ownership and the economic resources required on structures and processes for acute pain management. A standardized questionnaire on structures and processes of acute pain management was mailed to the 885 directors of German departments of anesthesiology listed as members of the German Society of Anesthesiology and Intensive Care Medicine (DGAI, Deutsche Gesellschaft für Anästhesiologie und Intensivmedizin). For most hospitals a strong regional competition existed; however, this parameter affected neither the implementation of structures nor the recommended treatment processes for pain therapy. In contrast, a clear preference for hospitals in private ownership to use the benchmarking tool QUIPS (quality improvement in postoperative pain therapy) was found. These hospitals also presented information on coping with the management of pain in the corporate clinic mission statement more often and published information about the quality of acute pain management in the quality reports more frequently. No differences were found between hospitals with different forms of ownership in the implementation of acute pain services, quality circles, expert standard pain management and the implementation of recommended processes. Hospitals with a higher case mix index (CMI) had a certified acute pain management more often. The corporate mission statement of these hospitals also contained information on how to cope with pain, presentation of the quality of pain management in the quality report, implementation of quality circles and the implementation of the expert standard pain management more frequently. There were no differences in the frequency of using the benchmarking

    Although outcomes for adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) are worse when treated according to adult rather than pediatric protocols, one criticism is that this may be due to the emancipation of young adults. Using case listing session of Surveillance, Epidemiology, and End Results (SEER) 18 (1973-2010), we examined outcomes for AYA with ALL defined similar to Cancer and Leukemia Group B (CALGB) 10,403 criteria (age 18-30) predicated on marital and insurance status as surrogates for emancipation (limiting analysis to 2007-2010). Analyses were conducted with SEER*Stat 8.1.2, Microsoft Excel 2007, and GraphPad Prism 6. Comparisons were made by the Fisher exact test and log rank test (Mantel-Cox); all P values were 2-sided. Although age (24 and younger vs. 25 and older) was predictive of median overall survival (OS) (not reached vs. 33; P = .0029) (3-year OS 66% vs. 49%), social factors were not. Three-year OS for insured versus uninsured patients was 61% versus 50%, and median OS was not reached versus 30 months (P = .2334). Three-year OS for single versus married patients was 62% versus 55%, with median OS not reached for both groups (P = .1084). Insurance status and marriage did not influence outcomes for AYA with ALL, suggesting that intrinsic differences in disease and disease-specific therapies are more important than social issues.

    The incidence of acute myocardial infarction (AMI) is rapidly increasing among older adults in Korea. However, the factors associated with a delayed decision to visit a hospital and the reasons for this delay have not been explored adequately among older patients. To determine factors predicting a prehospital delay time of > 6 h and to identify the cognitive barriers in the delayed decision of AMI patients aged ≥ 65 years. This study adopted a mixed methodological approach using quantitative and qualitative analyses. The sample included 94 male and 71 female patients hospitalized for first-time AMI at a university hospital in Korea. Thematic content analysis was used to identify the themes from the qualitative interview data, and multiple logistic regression analysis was used to predict delayed hospital presentation by > 6 h. The median prehospital delay time was 12 h. Low education level, presence of preinfarction angina pain, and attribution of symptoms to a non-cardiac origin were found to be the predicting factors. From the qualitative data, four meaningful themes including 10 subthemes that influenced the delayed decision were identified. Some culturally peculiar themes were found in this Korean sample. Educational strategies that focus on these cognitive decision-making barriers should be planned for elderly Korean at high risk for AMI.

  17. Acute hypoxia influences collagen and matrix metalloproteinase expression by human keratoconus cells in vitro.

    Directory of Open Access Journals (Sweden)

    Tina B McKay

    Full Text Available Keratoconus (KC is a progressive corneal ectasia linked to thinning of the central cornea. Hard contact lenses, rigid gas permeable lenses, and scleral lenses are the primary treatment modalities for early to mid- stages of KC to correct refractive error and astigmatism that develops as a result of an irregular corneal structure. These treatments are associated with significant drawbacks, including reduced availability of the tear film and oxygen to the corneal epithelium and stroma. However, it remains unknown whether hypoxia affects corneal integrity in the KC pathobiology. A number of studies have associated elevated oxidative stress with KC both in vitro and ex vivo. We hypothesized that KC-derived corneal fibroblasts are more susceptible to hypoxia-induced oxidative stress compared to healthy controls leading to exacerbation of corneal thinning in KC. This study investigated the effects of hypoxia on ECM secretion, assembly, and matrix metalloproteinase (MMP expression in human corneal fibroblasts from healthy controls (HCFs and KC patients (HKCs in vitro. HCFs and HKCs were cultured in 3D constructs for 3 weeks and maintained or transferred to normoxic (21% O2 or hypoxic (2% O2 conditions, respectively, for 1 additional week. At the 4 week time-point, constructs were isolated and probed for Collagen I, III, and V, keratocan and MMP-1, -2, -3, -9, and -13, as well as hypoxia markers, hypoxia inducible factor-1α and lactoferrin. Conditioned media was also collected and probed for Collagen I, III, and V by Western blot. Thickness of the ECM assembled by HCFs and HKCs was measured using immunofluorescence microscopy. Results showed that hypoxia significantly reduced Collagen I secretion in HKCs, as well as upregulated the expression of MMP-1 and -2 with no significant effects on MMP-3, -9, or -13. ECM thickness was reduced in both cell types following 1 week in a low oxygen environment. Our study shows that hypoxia influences collagen and MMP

    In medical settings, motivational interviewing-based "brief intervention" (BI) counseling reduces alcohol-related risk-taking behavior and harm in high-risk populations. Individuals arrested for driving under the influence of alcohol (DUI) are another at-risk population. We sought to determine whether a BI administered shortly after a first DUI arrest might decrease problematic drinking behavior. We conducted a single-center, parallel-group, double-blinded superiority randomized trial (NCT01270217), enrolling first-time DUI arrestees at a county jail from December 2010 through April 2011. Before their release, we randomized participants by computer-generated sequence to either a single BI or no discussion. We assessed 90-day change in Alcohol Use Disorders Identification Test (AUDIT) scores (range 0-40, higher values indicating more problematic drinking) as the primary outcome. We enrolled 200 subjects (100 to each arm), and 181 (90.5%, 86 control and 95 BI) completed the 90-day follow-up. Mean (SD) age was 30 (10) years, and 50% were men. Mean (SD) blood alcohol concentration upon arrest was 0.14% (0.04%). Mean (SD) baseline AUDIT scores were 8.8 (5.8) among control subjects and 7.7 (6.3) among BI subjects. At 90 days, AUDIT scores decreased by a mean (SD) 4.7 (5.1) units among control subjects and 3.4 (5.0) among BI subjects (difference, -1.3; 95% confidence interval [CI], -2.8 to +0.1). The likelihood of subsequent binge drinking [relative risk (RR) 1.6; 95% CI, 0.8-3.0; BI vs. control], abstinence (RR, 0.9; 95% CI, 0.4-2.1), alcohol-related injury to self or others (RR, 0.4; 95% CI, 0.1-2.4), and seeking treatment (RR, 1.2; 95% CI, 0.8-1.7) did not differ. A single BI counseling session shortly after first-time DUI arrest does not reduce 90-day self-reported drinking behavior or increase seeking treatment for drinking beyond that which occurs without such a discussion. Therapeutic study, level III.

    It is an important task for leadership to identify the motivating factors for employees and motivate them to fulfill their individual and organizational goals. Although there are several motivational factors (extrinsic and intrinsic), intrinsic motivational factors such as autonomy, mastery, and purpose are more important for deeper lasting job satisfaction and higher performance. In this article, the authors discuss how an understanding of these factors that influence motivation has the potential to transform an organization. Copyright © 2016 American College of Radiology.

    Rewards influence responses to acute painful stimuli, but the relationship of chronic pain to hedonic or motivational aspects of reward is not well understood. We independently evaluated hedonic qualities of sweet or bitter tastants and motivation to seek food reward in rats with experimental neuropathic pain induced by L5/6 spinal nerve ligation. Hedonic response was measured by implantation of intraoral catheters to allow passive delivery of liquid solutions, and "liking/disliking" responses were scored according to a facial reactivity scale. Spinal nerve ligation rats did not differ from controls in either "liking" or "disliking" reactions to intraoral sucrose or quinine, respectively, at postsurgery day 21, suggesting no differences in perceived hedonic value of sweet or bitter tastants. To assess possible motivational deficits during acute and chronic pain, we used fixed- and progressive-ratio response paradigms of sucrose pellet presentation in rats with transient inflammatory or chronic neuropathic pain. Assessment of response acquisition and break points under the progressive ratio schedule revealed no differences between sham and spinal nerve ligation rats for up to 120 days after injury. However, rats with inflammation showed decrements in lever pressing and break points on days 1 and 2 after complete Freund adjuvant injection that normalized by day 4, consistent with transient ongoing pain. Thus, although acute ongoing inflammatory pain may transiently reduce reward motivation, we did not detect influences of chronic neuropathic pain on hedonic or motivational responses to food rewards. Adaptations that allow normal reward responding to food regardless of chronic pain may be of evolutionary benefit to promote survival.

    Public health data show that early mortality in Hungary could be prevented by smoking cessation, reduced alcohol consumption, regular exercise, healthy diet and increased adherence. Doctor-patient encounters often highlight these aspects of health behavior. There is evidence that health behavior change is driven by internal motivation rather than external influence. This finding has led to the concept of motivational interview, which is a person-centered, goal-oriented approach to counselling. The doctor asks targeted questions to elicit the patient's motivations, strengths, internal resources, and to focus the interview around these. The quality and quantity of the patient's change talk is related to better outcomes. In addition, the interview allows the patient to express ambivalent feelings and doubts about the change. The doctor should use various communication strategies to resolve this ambivalence. Furthermore, establishing a good doctor-patient relationship is the cornerstone of the motivational interview. An optimal relationship can evoke change talk and reduce the patient's resistance, which can also result in a better outcome. The goal of the motivational interview is to focus on the 'why' to change health behavior rather than the 'how', and to utilize internal motivation instead of persuasion. This is the reason why motivational interview has become a widely-accepted evidence based approach. Orv Hetil. 2017; 158(34): 1331-1337.

    Elevated glucose levels on admission in many emergency conditions, including acute myocardial infarction (AMI), have been identified as a predictor of hospital mortality. Since there are no data in the literature related to stress hyperglycaemia (SH) in patients with both AIM and temporary electrical cardiac pacing, we aimed to investigate the influence of stress hyperglycaemia on the prognosis of patients with AMI and temporary electrical cardiac pacing. The prospective study included 79 patients with diagnosed AMI with ST-segment elevation (STEMI), admitted to the Coronary Care Unit of the Clinic for Cardiovascular Diseases, Clinical Centre Nis, from 2004 to 2007, who were indicated for temporary electrical cardiac pacing. The blood was sampled on admission for lab analysis, glucose levels were determined (as well as markers of myocardial necrosis troponin I, CK-MB). Echocardiographic study was performed and ejection fraction was evaluated by using area length method. The ROC analysis indicated that the best glycaemic level on admission, which could be used as a predictor of mortality, was 10.00 mmol/l, and the area under the curve was 0.82. In the group without SH, hospital mortality was 3-fold lower 11/48 (22.91%) compared to the group with SH 19/31 (61.29%), p 1, lower ejection fraction and heart rate, as well as systolic blood pressure. The best cut-off value for SH in patients with AMI (STEMI) and temporary electrical cardiac pacing is 10 mmol/l (determined by ROC curve) and may be used in risk stratification; patients with glucose levels 10 mml/l. Our results suggest that SH is a more reliable marker of poor outcome in AMI patients with temporary pace maker, without previously diagnosed DM.

    Full Text Available Objective: Treatment of acute lymphoblastic leukemia (ALL in adults focuses on the initial assessment of the prognostic relevant cytogenetic features as well as a response-guided therapy based on molecular data. We examined the importance of molecular-cytogenetic abnormalities for complete remission (CR rates and the overall survival (OS in adult ALLs.Materials and Methods: Conventional cytogenetics and fluorescence in situ hybridization were performed on bone marrow cells from 33 newly-diagnosed ALL adults. Two karyotype categories [standard- risk group- normal karyotype, hyperdiplody and other structural aberrations, and high-risk group-t(11q23/MLL, t(9;22/bcr-abl, t(1;19, t(8;14, C-MYC and complex karyotype] and the biologically and clinically relevant ALL ploidy subgroups were prospectively defined.Results: Chromosomal abnormalities were found in 52% of the cases with a high rate of poor-risk translocations - t(9;22, t(8q24, t(11q23, t(1;19. The total CR rate was 67% and the median time for achievement 2.33 months. Male sex, an age below 35 years and the absence of high risk translocations might have contributed to the high CR rates. Female patients, hyperdiplody, low white blood cells (WBC, and random cytogenetic aberrations had the longest OS. OS, 3- and 5-years survival periods were significantly shorter for poor-risk than standard risk group (p=.015, p=.001 and p=.005, respectively.Conclusion: This study emphasizes the lack of influence of cytogenetic aberrations on the CR and the time to achieve CR. However, our observations show that these aberrations are an independent prognostic factor in adult ALL - they allow predicting therapy resistance and the OS time after intensetreatment.

  12. Influence of melanocytes in the ex-vivo reconstructed epidermal melanin unit following an acute UV irradiation

    Influence of melanocytes in skin pigmentation is well documented, however its photo-protective role has given rise to controversy. The role of melanocytes have been investigated on reconstructed epidermis with 100 % of keratinocytes or 95 % of keratinocytes and 5 % of melanocytes. In a first time, the effect of an acute UVB dose has been studied on both reconstructed epidermis, next we have investigated UVA and UVA+B effects on these epidermis. Following irradiation, the presence of melanocytes in reconstructed epidermis protects against apoptosis without protecting significantly against DNA damage formation (CPD, 6-4PP) and protects against UV-induced unbalance of the SOD/catalase ratio (antioxidants enzymes). On the contrary, the presence of melanocytes in reconstructed epidermis amplifies lipids and proteins oxidations but seems to protect against DNA oxidations. Melanocytes differ from keratinocytes by their melanin content and their more important concentration in polyunsaturated fatty acids. To evaluate what is the part of melanin and the part of polyunsaturated fatty acids in epidermal UV responses, reconstructed epidermis with keratinocytes have been supplemented with polyunsaturated fatty acid. This study indicates that polyunsaturated fatty acids are responsible for lipids and proteins oxidations and that melanin protect against DNA oxidation induced by lipid peroxidation. All these studies demonstrate that, model of reconstructed epidermis and epidermis in-vivo have the same behaviour following UV irradiation. In the last part, sunscreens and antioxidants have been tested on reconstructed epidermis and have demonstrated that model of reconstructed epidermis is suitable for photo-protective molecules screening.

  13. Heart rate variability in acute coronary syndrome patients with major depression: influence of sertraline and mood improvement.

    2007-09-01

    Major depressive disorder (MDD) associated with acute coronary syndrome (ACS) increases the risk of mortality. Decreased heart rate variability (HRV), also a predictor of mortality, is reduced in patients with MDD after ACS, and has been suggested to be a mediator of MDD mortality after ACS. Although selective serotonin reuptake inhibitors may reduce mortality post-ACS, little is known about their effects on HRV. To examine the influence of both sertraline and improvement in mood on HRV. The Sertraline Antidepressant Heart Attack Randomized Trial assessed HRV from 24-hour Holter electrocardiogram recordings at baseline in 290 patients and from a second recording in 258 of these patients 16 weeks after randomization to sertraline or placebo. Frequency domain measures of HRV included high-frequency power, low-frequency power, very low-frequency power, ultra low-frequency power, and total power. Depression severity was measured by the Hamilton Rating Scale for Depression. Clinical response was measured with the Clinical Global Impressions Improvement scale. At baseline, prior episodes of MDD were associated with lower HRV. Sertraline significantly increased ultra low-frequency power, while improvement in mood was associated with higher low-frequency power independent of treatment. However, the expected recovery in HRV following ACS was not observed in patients with MDD. Higher ultra low-frequency during sertraline treatment and higher low-frequency power in patients whose mood improved resulted primarily from these measures decreasing in their comparison groups. Heart rate variability recovery is impaired in depressed patients after ACS. Previously reported differences in baseline HRV between patients with and without depression after ACS grew larger in the 16 weeks following a coronary event. Both sertraline treatment and symptomatic recovery from depression were associated with increased HRV compared with placebo-treated and nonrecovered post-ACS control groups

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

    To analyse risk factors for early acute cerebrovascular accidents following off-pump coronary artery bypass grafting (OPCAB) in patients with stroke history, and to propose preventive measures to reduce the incidence of these events. A total of 468 patients with a history of stroke underwent OPCAB surgery in Beijing Anzhen Hospital of China from January 2010 to September 2012. They were retrospectively divided into two groups according to the occurrence of early acute cerebrovascular accidents within 48 hours following OPCAB. Multivariate logistic regression analysis was used to find risk or protective factors for early acute cerebrovascular accidents following the OPCAB. Fifty-two patients (11.1%) suffered from early acute cerebrovascular accidents in 468 patients, including 39 cases of cerebral infarction, two cases of cerebral haemorrhage, 11 cases of transient ischaemic attack (TIA). There were significant differences between the two groups in preoperative left ventricular ejection fraction ≤ 35%, severe bilateral carotid artery stenosis, poorly controlled hypertension, intraoperative application of Enclose® II proximal anastomotic device, postoperative acute myocardial infarction, atrial fibrillation, hypotension, ventilation time > 48h, ICU duration >48h and mortality. Multivariate logistic regression analysis showed that preoperative severe bilateral carotid stenosis (OR=6.378, 95%CI: 2.278-20.987) and preoperative left ventricular ejection fraction ≤ 35% (OR=2.737, 95%CI: 1.267-6.389), postoperative acute myocardial infarction (OR=3.644, 95%CI: 1.928-6.876), postoperative atrial fibrillation (OR=3.104, 95%CI:1.135∼8.016) and postoperative hypotension (OR=4.173, 95%CI: 1.836∼9.701) were independent risk factors for early acute cerebrovascular accidents in patients with a history of stroke following OPCAB procedures, while intraoperative application of Enclose® II proximal anastomotic device was protective factor (OR=0.556, 95%CI: 0.337-0.925).

    Purpose Ongoing traumatic events and stressors, rather than acute sources of trauma, may shape long-term post-disaster mental health. The purpose of this study was to compare the influence of acute hurricane-related exposures and ongoing post-hurricane exposures on the short- and long-term course of posttraumatic stress symptoms (PTSS) and functional impairment (FI). Methods A random sample of adults (n=658) in Galveston and Chambers Counties, Texas, was selected 2–6 months after Hurricane Ike and interviewed 3 times over eighteen months. Hurricane-related exposures included traumatic events such as death of a family member due to the hurricane and stressors such as loss/damage to personal property due to the hurricane. Post-hurricane exposures included traumatic events such as sexual assault and stressors such as divorce or serious financial problems. Results Experiencing an acute hurricane-related traumatic event or stressor was associated with initial post-hurricane PTSS [RR=1.92(95% CI=1.13–3.26) and RR=1.62(1.36–1.94), respectively] and FI [RR=1.76; (1.05–2.97) and RR=1.74(1.46–2.08)], respectively, and acute hurricane-related stressors were associated with a higher rate of increase in FI over time [RR=1.09; (1.01–1.19)]. In contrast, ongoing post-hurricane daily stressors were not associated within initial PTSS and FI, but were associated with PTSS and FI at the second and third interviews. Conclusions While immediate postdisaster interventions may influence short-term mental health, investment in the prevention of ongoing stressors may be instrumental to manage long-term mental health status.

    The Japanese guidelines for acute otitis media in children recommend classifying acute otitis media by age, manifestations and local findings, and also recommend myringotomy for moderate-grade cases with severe local findings, severe-grade cases, and treatment-resistant cases. The heptavalent pneumococcal conjugate vaccine was released in Japan in February 2010. In Hiroshima City, public funding allowing free inoculation with this vaccine was initiated from January 2011, and the number of vaccinated individuals has since increased dramatically. This study investigated changes in the number of myringotomies performed to treat acute otitis media during the 5-year period from January 2008 to December 2012 at two hospitals and five clinics in the Asa Area of Hiroshima City, Japan. A total of 3,165 myringotomies for acute otitis media were performed. The rate of procedures per child-year performed in otitis media in 1-year-old infants decreased significantly in the 2 years after the introduction of public funding for heptavalent pneumococcal conjugate vaccine compared to all years before introduction (potitis media in reducing the financial burden of myringotomy. In addition, this vaccine may help prevent acute otitis media with severe middle ear inflammation in 1-year-old infants.

    Picci, Patrizia; Battistelli, Adalgisa

    The current work seeks to focus on the innovative work behavior and, in particular, on the stage of idea generation. An important factor that stimulates the individual to carry out the various emergent processes of change and innovation within the organization is known as intrinsic motivation, but under certain conditions, the presence of different forms of extrinsic motivation, as external regulation, introjection, identification and integration, positively influences innovative behavior at work, specifically the creative stage of the process. Starting from this evidence, the organizational environment could be capable of stimulating or indeed inhibiting potential creativity and innovation of individuals. About 100 individuals employees of a local government health department in Central Italy were given an explicit questionnaire. The results show that among external factors that effect the individual such as control, rewards and recognition for work well done, controlled motivation influences overall innovative behavior whereas autonomous motivation plays a significant role in the specific behavior of idea generation. At the same time, it must also be acknowledged that a clearly articulated task which allows an individual to identify with said task, seems to favor overall innovative behavior, whilst a task which allows a fair degree of autonomy influences the behavior of generating ideas.

    We examined the sexual motives underlying sexual self-labels among Chinese men who have sex with men. A total of 60 bottoms, 120 versatiles, and 48 tops participated in a Web-based survey. Our results showed that tops were more likely to desire exerting power over their partners during sex, while bottoms were more likely to desire being overpowered by their partners. There were no significant sexual self-label differences in the sexual motives of wanting intimacy and the desire for pleasure. The intimacy and power ratings differed across sexual activities and sex positions. There was a tendency for sexual positions in which the performer was facing the receiver to be rated as more intimate than those in which the performer was facing away from the receiver, and for individuals who preferred to be insertive to feel more powerful in sexual positions in which their partner was kneeling down or standing than those in which their partner was sitting or lying down. Tops were significantly more likely than bottoms to engage in insertive sexual positions, while bottoms were significantly more likely to engage in receptive sexual positions. Both tops and bottoms were more likely to engage in the corresponding insertive/receptive position when the insertive position was rated as more powerful than the receptive position. Our results suggest that the concordance between sexual self-labels and sexual position preferences may rely on the power difference between the insertive and receptive positions in addition to body characteristics.

    Extant research in political science has demonstrated that citizens’ opinions on policies are influenced by their attachment to the party sponsoring them. At the same time, little evidence exists illuminating the psychological processes through which such party cues are filtered. From the psychol...... of the motivated reasoning hypothesis, demonstrate that across student and nationally representative samples, the presence of party cues increases processing effort....... the psychological literature on source cues, we derive two possible hypotheses: (1) party cues activate heuristic processing aimed at minimizing the processing effort during opinion formation, and (2) party cues activate group motivational processes that compel citizens to support the position of their party....... As part of the latter processes, the presence of party cues would make individuals engage in effortful motivated reasoning to produce arguments for the correctness of their party’s position. Following psychological research, we use response latency to measure processing effort and, in support...

    The influence of natural dissolved organic matter (DOM) on acute waterborne Cu toxicity was evaluated in the euryhaline copepod Acartia tonsa at 3 different water salinities. Three sources of freshwater DOM (extracted by reverse osmosis) and 2 sources of marine DOM (extracted using a solid-phase technique) were used. Artificial salt water was used to prepare the experimental media. Different combinations of Cu concentrations and DOM sources and concentrations were tested at salinities of 5, 15, and 30 ppt. Toxicity data (48-h median lethal concentration [LC50] values) were calculated based on dissolved Cu concentrations. In a broad view, data showed that increasing salinity was protective against the acute waterborne Cu toxicity. In general, Cu toxicity was also lower in the presence than in the absence of DOM. Toxicity (48-h LC50) values from all treatments at the same salinity showed a positive linear relationship with the dissolved organic carbon (DOC). Thus, the protective effect of DOM against the acute Cu toxicity seems to be dependent mainly on the DOM concentration. However, it seems also to be dependent to some extent on the source of DOM used. In summary, findings reported in the present study clearly indicate that both salinity and DOM (source and concentration) should be taken into account in the development of an estuarine version of the biotic ligand model.

    In this study, we attempted to analyze the impact of insurance based health care system and treatment compliance on the outcome of adolescent and adults with acute lymphoblastic leukemia (ALL). Patients who underwent treatment for ALL during the period 2003-2011 were enrolled into this retrospective study. Patients on supportive or palliative care only and patients with age <10 years were excluded. The hospital records and tumor registry records were studied. Patients were stratified into two groups, Group A (prior to the introduction of state health insurance [SHI], 2003-2007) and Group B (after the introduction of SHI, 2008-2011). Overall survival (OS) was calculated using Kaplan-Meier method. A total of 420 patients with suspected or confirmed ALL visited our center during the study period and 179 patients (87 in Group A and 92 in Group B) were considered for inclusion. The median age in years (range) was 18 (10-57) and 18 (10-58) respectively in Groups A and B with males more than females. Median OS (95% CI) was 9 (6.7-11.2) and 12 (7.3-16.7) months in the Groups A and B respectively (P = 0.265). Poor treatment compliance in both groups was high (36% in Group A and 41% in Group B, [P = 0.107]) with lower default rates in Group B (P = 0.019). Patients with good compliance in the total study population and the individual study groups had significantly better OS. Insurance based health care has improved outcomes in the present study but not compliance to treatment. Significantly better OS was observed in patients with good compliance.

    Motivated employees are crucial to organizations, but external interventions such as command systems and financial incentives may decrease motivation. If these external interventions are perceived to be controlling, they are expected to crowd out intrinsic motivation, and this may also apply...... to other types of autonomous motivation such as public service motivation. The perception of external interventions is thus expected to be vital. This article investigates how the perception of a specific command system (obligatory student plans) is associated with intrinsic motivation and public service...... 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....

    Full Text Available Buyer behavior of consumers plays one of the key roles in fulfillment of the main goals of a company. It is influenced by many external and internal factors but the company can also influence the final process of buyer decision-making process significantly by its activities. The subject matter of this article is an analysis of the features of online buyer behavior compared to the general regularities of buyer behavior, definition of the main motives of online shopping, and description of the current trends. The article uses the basic terminology of this subject and current bibliography as well as other resources. Theoretical knowledge is based on historic directions of Maslow’s theory of motivation where it is possible to find the basis for a buyer behavior analysis. The article is also based on the formerly carried out questionnaire survey which examines the motives and experience of the respondents with online shopping. By means of the independence test it is verified whether there is a relation between the age of respondents and motivation for online shopping. Subsequently, the survey carried out in person is compared with other relevant research solutions.

    The aim of the investigation was to evaluate bio electric activity of the heart after acute gamma-irradiation and the hypoxia. Female rats (5 - 6 month old) was acute irradiated at 0,5 Gy dose (dose rate 0,1 mGy/sec) and was examined in a 10, 30, 90 and 180 days later. Electrophysiological study of the isolated right rat auricle was conducted by means of microelectrode registration of intracellular bio electric activity. It was shown that gamma-irradiation at 0,5 Gy resulted in decrease of amplitude and duration of action potentials of right auricle cells, attenuation of the dependence of the electrophysiological characteristics upon the stimulation frequency. Exposure of the rats to acute gamma-irradiation leaded to the depression of the interval of the cardio myocyte reaction on the hypoxia. The revealed post-radiation changes determined the reduction in function resistance of heart cells bio electric activity and can promote the initiation of arrhythmias

    1999-06-01

    Three hundred and six (306) undergraduates participated in a study that examined abilities in interpersonal relations and interpersonal motivations. Results indicated that: (1) Three interpersonal motivations underlay interpersonal attitudes, namely, other-praise acquisition, other-rejection avoidance, and relationship avoidance. (2) Abilities in interpersonal relations, such as social skills and perceived interpersonal competence, influenced relative strengths among the individual's three interpersonal motivations. High levels of abilities in interpersonal relations lead to stronger motivation to acquire praise by others. In contrast, those with low levels of abilities were motivated to avoid interpersonal relations altogether. Those in-between were motivated to avoid rejection by others.

    The incidence of liver cancer is higher in men than in women. This sex difference is also observed in murine tumor induction models that result in the appearance of liver tumors in adult mice following their exposure on postnatal days 8 and/or 15 to carcinogens such as 4-aminobiphenyl (ABP) or diethylnitrosamine (DEN). Previous studies performed in adult mice showed that acute hepatotoxic and inflammatory responses to high-dose DEN exposure were greater in males than in females, leading to the suggestion that these responses could account for the sex difference in tumor development. We also recently observed that female but not male mice exposed postnatally to ABP had slightly increased expression of the antioxidant defense genes Nqo1 and Ggt1, which are regulated by the oxidative stress response protein nuclear factor erythroid 2-related factor 2 (NRF2), while expression of Hmox1 was increased in both sexes. The goal of the present study was therefore to compare selected acute hepatotoxic, inflammatory and oxidative stress defense responses to ABP, DEN, or the prototype hepatotoxicant carbon tetrachloride (CCl 4 ), in male and female mice exposed to these chemicals either postnatally or as adults. Exposure of adult mice to ABP, DEN or CCl 4 produced a 2-fold greater acute elevation in serum levels of the hepatotoxicity biomarker alanine aminotransferase (ALT) in males than in females, while levels of the inflammatory biomarker interleukin-6 (IL-6) showed no sex difference. However, treatment of immature mice with either ABP or DEN using standard tumor-inducing postnatal exposure protocols produced no increase in serum ALT or IL-6 levels in either males or females, while CCl 4 produced a 40-fold ALT elevation but with no sex difference. Basal expression of the NRF2-responsive gene Nqo1 was higher in adult females than in males, but there was no sex difference in basal expression of Ggt1 or Hmox1. Sexually immature animals showed no sex difference in basal

    Concepts from theories of motivation are used to suggest methods for improving the motivational environment of hospital pharmacy departments. Motivation--the state of being stimulated to take action to achieve a goal or to satisfy a need--comes from within individuals, but hospital pharmacy managers can facilitate motivation by structuring the work environment so that it satisfies employees' needs. Concepts from several theories of motivation are discussed, including McGregor's theory X and theory Y assumptions, Maslow's hierarchy of needs theory, Herzberg's motivation hygiene theory, and Massey's value system theory. Concepts from the Japanese style of management that can be used to facilitate motivation, such as quality circles, also are described. The autocratic, participative, and laissez faire styles of leadership are discussed in the context of the motivation theories, and suggested applications of theoretical concepts to practice are presented.

    Full Text Available Research question (RQ: The research deals with the question of how employees are motivated for mutual communication and transfer of information needed for smooth functioning of work processes. Another question is how much awards affect motivation of employees in the organization. Purpose: The purpose of the research was to determine the connection between motivation and communication of employees in the organization. What is the influence of remuneration on positive motivation and successful communication and how this is connected with effective achievement of goals set in the organization? Method: The research was carried out by a Likert-type scale to study perception of motivation with communication of employees in the organization. Employees of the sales organization were part of the research study. Results: The results show that employees' communication has an influence on motivation of employees in the sales organization. Furthermore, the results show that suitable communication increases working motivation and that employees are satisfied with communication at their workplace. Organization: Communication among employees is vital for a successful organization. The employees of the sales organization were aware of the fact that their company cannot be successful without proper motivation for communication. This research study shows that proper communication increases working motivation in the organization, but the questionnaire should be carried out systematically to determine progress and improvement on a longitudinal basis. Society: Establishing communication in a sales organization is very important because communication happens among colleagues as well as among buyers who contribute to the success of the business. Originality: The goal of the research was to determine the connection between motivation and communication of the employees in a sales organization. The research was carried out to define weaknesses of communication to suggest
