Précis of Social Perception and Social Reality: Why accuracy dominates bias and self-fulfilling prophecy.

Science.gov (United States)

Jussim, Lee

2017-01-01

Social Perception and Social Reality (Jussim 2012) reviews the evidence in social psychology and related fields and reaches three conclusions: (1) Although errors, biases, and self-fulfilling prophecies in person perception are real, reliable, and occasionally quite powerful, on average, they tend to be weak, fragile, and fleeting. (2) Perceptions of individuals and groups tend to be at least moderately, and often highly accurate. (3) Conclusions based on the research on error, bias, and self-fulfilling prophecies routinely greatly overstate their power and pervasiveness, and consistently ignore evidence of accuracy, agreement, and rationality in social perception. The weight of the evidence - including some of the most classic research widely interpreted as testifying to the power of biased and self-fulfilling processes - is that interpersonal expectations relate to social reality primarily because they reflect rather than cause social reality. This is the case not only for teacher expectations, but also for social stereotypes, both as perceptions of groups, and as the bases of expectations regarding individuals. The time is long overdue to replace cherry-picked and unjustified stories emphasizing error, bias, the power of self-fulfilling prophecies, and the inaccuracy of stereotypes, with conclusions that more closely correspond to the full range of empirical findings, which includes multiple failed replications of classic expectancy studies, meta-analyses consistently demonstrating small or at best moderate expectancy effects, and high accuracy in social perception.
Are public opinion polls self-fulfilling prophecies?

Directory of Open Access Journals (Sweden)

David Rothschild

2014-08-01

Full Text Available Psychologists have long observed that people conform to majority opinion, a phenomenon sometimes referred to as the ‘bandwagon effect’. In the political domain people learn about prevailing public opinion via ubiquitous polls, which may produce a bandwagon effect. Newer types of information – published probabilities derived from prediction market contract prices and aggregated polling summaries – may have similar effects. Consequently, polls can become self-fulfilling prophecies whereby majorities, whether in support of candidates or policies, grow in a cascading manner. Despite increased attention to whether the measurement of public opinion can itself affect public opinion, the existing empirical literature is surprisingly limited on the bandwagon effects of polls. To address this gap, we conducted an experiment on a diverse national sample in which we randomly assigned people to receive information about different levels of support for three public policies. We find that public opinion as expressed through polls affects individual-level attitudes, although the size of the effect depends on issue characteristics.
Self-Verification as a Mediator of Mothers’ Self-Fulfilling Effects on Adolescents’ Educational Attainment

Scherr, Kyle C.; Madon, Stephanie; Guyll, Max; Willard, Jennifer; Spoth, Richard

2013-01-01

This research examined whether self-verification acts as a general mediational process of self-fulfilling prophecies. The authors tested this hypothesis by examining whether self-verification processes mediated self-fulfilling prophecy effects within a different context and with a different belief and a different outcome than has been used in prior research. Results of longitudinal data obtained from mothers and their adolescents (N = 332) indicated that mothers’ beliefs about their adolescents’ educational outcomes had a significant indirect effect on adolescents’ academic attainment through adolescents’ educational aspirations. This effect, observed over a six year span, provided evidence that mothers’ self-fulfilling effects occurred, in part, because mothers’ false beliefs influenced their adolescents’ own educational aspirations which adolescents then self-verified through their educational attainment. The theoretical and applied implications of these findings are discussed. PMID:21357755

2010-01-01

This research examined whether self-fulfilling prophecy effects are mediated by self-verification, informational conformity, and modeling processes. The authors examined these mediational processes across multiple time frames with longitudinal data obtained from two samples of mother – child dyads (N1 = 487; N2 = 287). Children’s alcohol use was the outcome variable. The results provided consistent support for the mediational process of self-verification. In both samples and across several years of adolescence, there was a significant indirect effect of mothers’ beliefs on children’s alcohol use through children’s self-assessed likelihood of drinking alcohol in the future. Comparatively less support was found for informational conformity and modeling processes as mediators of mothers’ self-fulfilling effects. The potential for self-fulfilling prophecies to produce long lasting changes in targets’ behavior via self-verification processes are discussed. PMID:18665708

The importance of normative beliefs to the self-prophecy effect.

Science.gov (United States)

Sprott, David E; Spangenberg, Eric R; Fisher, Robert

2003-06-01

Asking people to predict whether they will undertake a target behavior increases their probability of performing that behavior. Now referred to as the self-prophecy effect, this phenomenon has been demonstrated across several contexts. Although theoretical explanations for the effect have been offered, empirical evidence for proposed accounts is sparse. The current research tests the theoretically relevant precondition for the effect that normative beliefs--evaluations of what is socially desirable or appropriate--underlie manifestation of the self-prophecy effect. Results of 2 experiments for different behaviors indicate that the act of making a prediction is most effective when normative beliefs are strong. Implications of these findings are discussed in relation to theoretical explanations for the effect and successful use of self-prophecy to promote socially desirable behaviors.
父母期望的自证预言效应农民工子女研究%The Self-Fulfilling Prophecy of Parents＇ Expectations： Findings from Migrant Workers＇ Children

自证预言效应广泛存在于社会生活各个领域。本文在概要评述自证预言概念的缘起、发展及其实现过程的基础上，运用质性研究与量化研究相结合的三角测量法，考察了农民工子女的父母期望对其学业成就的影响。研究认为，父母期望具有强有力的自证性影响。在“父母感知”与“孩子学业成绩”之间的相关关系中，有3／5是源于父母期望的自我证实。研究还发现，亲子沟通质量是父母期望正确性的调节变量，父母期望存在着言语报告和行为表现上的不一致。%The self-fulfilling prophecy is a powerful, pervasive phenomenon. This study examined whether migrant worker parents＇ expectations about their children＇s academic performance influenced the children＇ s future academic achievements. This study employed both quantitative and qualitative methods. Specifically, the former included a questionnaire survey, and the latter mainly was in-depth interviewing. The study targets were migrant workers and their children. This paper first reviews the origin and evolution of the self-fulfilling prophecy concept, and summarizes the existing research findings. Most studies have focused on the effects of teachers＇ expectations on students＇ academic achievements. The effects of parents＇ expectations on their children＇s performance are overlooked. Actually, because parents are playing important roles in the lives of their children, the effects of their expectations deserve attention. The quantitative analyses indicated that three out of the five coefficients about the relationships between parents＇ expectations and children＇ s academic performance could be attributed to the self-fulfilling effects of parents＇ expectations, and the rest two to the accuracy of the expectations. Self-fulfilling prophecies, by definition, start with inaccurate expectations. In this model, inaccuarcy is the component of parent perceptions

We analyze overt and covert forms of actualization of such ideas. We describe the basic mechanisms of their action (actualization of social identity, negative emotions, extraneous thoughts, increased self-control, difficulty in learning, reduction of self-efficacy, increased motivation of avoidance, de-identification with the area of activity. We highlight the main ways to reduce the “stereotype threat” focused on social identity (actualization or creating a new identity, stereotypes (from the removal of stereotype stimuli to demonstration of positive behaviors, task (modified instruction and individual human characteristics (higher self-efficacy, learning coping strategies.

The Iron Law of Financial Markets: Self-fulfilling Prophecies and Speculative Booms and Busts

2016-02-01

Full Text Available This paper discusses the factors which, in the absence of strong financial regulation, sustain the Iron Law of the Financial Markets asserting that speculative booms and busts occur more or less regularly from 17 century to the present. The first factor is that financial markets are self-fulfilling system. The second is that human nature does not change and is based on egoism, materialism, loss aversion, exaggerated hopes and fears, emulation, propensity to gamble, herd behavior and so on. Lastly, there is the extreme brevity of the financial memory. In order to enable economic authorities and/or individuals to detect timely that the unsustainable boom is under the way, we have identified the common features of historically recorded speculative episodes. Stages through which the system passes on its way from unsustainable rise to inevitable fall are: displacement, boom, overtrading, financial distress and discredit or revulsion.
Self-consistency in Capital Markets

Science.gov (United States)

Benbrahim, Hamid

2013-03-01

Capital Markets are considered, at least in theory, information engines whereby traders contribute to price formation with their diverse perspectives. Regardless whether one believes in efficient market theory on not, actions by individual traders influence prices of securities, which in turn influence actions by other traders. This influence is exerted through a number of mechanisms including portfolio balancing, margin maintenance, trend following, and sentiment. As a result market behaviors emerge from a number of mechanisms ranging from self-consistency due to wisdom of the crowds and self-fulfilling prophecies, to more chaotic behavior resulting from dynamics similar to the three body system, namely the interplay between equities, options, and futures. This talk will address questions and findings regarding the search for self-consistency in capital markets.
The role of need fulfillment in relationship functioning and well-being: a self-determination theory perspective.

Science.gov (United States)

Patrick, Heather; Knee, C Raymond; Canevello, Amy; Lonsbary, Cynthia

2007-03-01

Self-determination theory posits 3 basic psychological needs: autonomy (feeling uncoerced in one's actions), competence (feeling capable), and relatedness (feeling connected to others). Optimal well-being results when these needs are satisfied, though this research has traditionally focused on individual well-being outcomes (e.g., E. L. Deci & R. M. Ryan, 2000). Three studies examined the role of need fulfillment in relationship functioning and well-being. Study 1 found that fulfillment of each need individually predicted both individual and relationship well-being, with relatedness being the strongest unique predictor of relationship outcomes. Study 2 found that both partners' need fulfillment uniquely predicted one's own relationship functioning and well-being. Finally, in Study 3, the authors used a diary recording procedure and tested a model in which the association between need fulfillment and relationship quality was mediated by relationship motivation. Those who experienced greater need fulfillment enjoyed better postdisagreement relationship quality primarily because of their tendency to have more intrinsic or autonomous reasons for being in their relationship. 2007 APA, all rights reserved

Within-person variation in security of attachment: a self-determination theory perspective on attachment, need fulfillment, and well-being.

Science.gov (United States)

La Guardia, J G; Ryan, R M; Couchman, C E; Deci, E L

2000-09-01

Attachment research has traditionally focused on individual differences in global patterns of attachment to important others. The current research instead focuses primarily on within-person variability in attachments across relational partners. It was predicted that within-person variability would be substantial, even among primary attachment figures of mother, father, romantic partner, and best friend. The prediction was supported in three studies. Furthermore, in line with self-determination theory, multilevel modeling and regression analyses showed that, at the relationship level, individuals' experience of fulfillment of the basic needs for autonomy, competence, and relatedness positively predicted overall attachment security, model of self, and model of other. Relations of both attachment and need satisfaction to well-being were also explored.
Something's missing: need fulfillment and self-expansion as predictors of susceptibility to infidelity.

Science.gov (United States)

Lewandowski, Gary W; Ackerman, Robert A

2006-08-01

The present authors investigated whether an individual's motivations that are related to need fulfillment and self-expansion within a romantic relationship can predict self-reported susceptibility to infidelity. A sample of 109 college students (50 men, 59 women) who were in dating relationships completed questionnaires that assessed 5 types of variables of need fulfillment (i.e., intimacy, companionship, sex, security, and emotional involvement), 3 types of self-expansion variables (i.e., self-expansion, inclusion of the other in the self, and potential for self-expansion), and susceptibility to infidelity. As the present authors predicted, both sets of predictors (need fulfillment and self-expansion) significantly contributed to the variance in susceptibility to infidelity. The present findings indicated the possibility that, when a relationship is not able to fulfill needs or provide ample self-expansion for an individual, his or her susceptibility to infidelity increases.
The effects of feedback self-consistency, therapist status, and attitude toward therapy on reaction to personality feedback.

Science.gov (United States)

Collins, David R; Stukas, Arthur A

2006-08-01

Individuals' reactions to interpersonal feedback may depend on characteristics of the feedback and the feedback source. The present authors examined the effects of experimentally manipulated personality feedback that they--in the guise of therapists--e-mailed to participants on the degree of their acceptance of the feedback. Consistent with Self-Verification Theory (W. B. Swann Jr., 1987), participants accepted feedback that was consistent with their self-views more readily than they did feedback that was inconsistent with their self-views. Furthermore, the authors found main effects for therapist's status and participant's attitude toward therapy. Significant interactions showed effects in which high-status therapists and positive client attitudes increased acceptance of self-inconsistent feedback, effects that were only partially mediated by clients' perceptions of therapist competence. The present results indicate the possibility that participants may be susceptible to self-concept change or to self-fulfilling prophecy effects in therapy when they have a positive attitude toward therapy or are working with a high-status therapist.

Critical prophecy and political leadership in biblical, African and Islamic worldviews

Directory of Open Access Journals (Sweden)

P.O. Abioje

2010-07-01

Full Text Available This article examines the socio-political influence of prophecy in traditional African and the biblical perspectives, in order to challenge contemporary African religious men and women to serve as the conscience of society. There is hardly any doubt that political leaders are usually prone to abuse of their positions and they need to be reprimanded and lampooned. A discussion on Islam is included, because, together with Christianity, it dominates, to a large extent, socio-political and economic leadership in Africa. It is the view of many scholars that neither Christianity nor Islam have been applied sufficiently to political leadership in Africa to have an impact on mass socio-political and economic welfare, although some heroic individual exceptions are noted. The materials were gathered through a literature study. The study is comparative in the sense that it compares prophecy in traditional Africa with what is obtained from the Bible and the church as we know it today. The study recommends critical prophecy in the two dominant Old Testament religions, namely Christianity and Islam, and in African Traditional Religion, for improved political leadership and development in Africa.

Monuments to Academic Carelessness: The Self-fulfilling Prophecy of Katherine Frost Bruner.

Science.gov (United States)

Rekdal, Ole Bjørn

2014-09-01

In 1942, Katherine Frost Bruner published an article titled "Of psychological writing: Being some valedictory remarks on style." It was published in Journal of Abnormal and Social Psychology , the journal for which she served as editorial assistant between 1937 and 1941. Her collection of advice to writing scholars has been widely quoted, including by several editions of The Publication Manual of the American Psychological Association . The most frequently quoted message in Bruner's article deals with the importance of making sure that references in academic texts are complete and accurate. Exploring the citation history of this particular message reveals an ironic point: the great majority of those who have quoted Bruner's words on reference accuracy have not done so accurately. The case may serve as a reminder of the importance of the basic academic principle of striving to use primary sources. The most startling finding in this study is how frequently this principle is violated, even by authors who advise and educate academic writers.

Full Text Available Este estudio analiza si el valor otorgado a la evidencia a favor y en contra de la hipótesis de gestión continuada, se ve afectada por las percepciones que los auditores tienen sobre la validez de la hipótesis de la profecía autocumplida. Hemos realizado un experimento en el que una muestra de auditores debe someter a estudio la continuidad de una hipotética empresa, basándose tanto en información financiera como en determinada evidencia tanto a favor como en contra de la continuidad de ésta. Los resultados obtenidos sugieren que los auditores que muestran una fuerte creencia en la validez de la hipótesis de la profecía autocumplida otorgan mayor valor probatorio a la evidencia a favor de la hipótesis de continuidad. Por el contrario, los auditores que no muestran una fuerte creencia en la hipótesis de la profecía autocumplida otorgan un mayor valor probatorio a la evidencia en contra de la continuidad.This paper analyzes whether auditors are affected by the so called “self-fulfilling prophecy effect” (in terms of perceptions when evaluating clients’ going concern status. We designed a laboratory experiment to examine auditors’ attitude to both negative and positive evidence in the case of a fictitious financially distressed client. Our results show that those auditors more sensitive to the self-fulfilling prophecy effect offered a higher tendency to rely on the negative factors. On the other hand, those auditors less worried about the self-fulfilling prophecy effect showed a higher tendency to rely on the positive factors.

Full Text Available Scholarly interest in the thought and teachings of Shâh Waliyyullâh adDihlawî has increased in recent years –not surprisingly, given the richness and profundity of his writings. This article explores the mystical dimension of prophecy emerging from Shâh Waliyyullâh’s insights and remarks, focusing on the key concepts such as the World of Images (‘Âlam al-Mithâl, the Highest Council of Angels (al-Mala’ al-A‘lâ and the Holy Enclave (Haz} îrat al-Quds, which help explain how, from the sûfî point of view, prophecy is possible. The main task of a prophet is to set up order in social, political and economic life of people. The prophet receives revelation which enables him to communicate the Divine Message to mankind containing all that is necessary for their welfare both in this life and the next according to the Divine Plan.
Using self-determination theory to explain sport persistence and dropout in adolescent athletes.

Science.gov (United States)

García Calvo, Tomás; Cervelló, Eduardo; Jiménez, Ruth; Iglesias, Damián; Moreno Murcia, Juan Antonio

2010-11-01

Motivational characteristics are influential in shaping adolescents' desire to persist in sport or to discontinue their sport participation. Self-determination theory (Deci & Ryan, 2000) was utilized as the theoretical framework for this study. This theory examines whether sustained participatory involvement, defined as continued participation in the sport through the next year, was influenced by individuals' self-determined motivation and by the fulfillment of the three basic psychological needs of autonomy, competence, and relatedness. Four hundred ninety two soccer players between the ages of 13 and 17 years comprised the sample. Results indicated sport dropout was explained by higher levels of amotivation, external regulation, and introjected regulation and by lower satisfaction of relatedness and autonomy needs. The findings of this study contribute to the knowledge base on sport dropout as they supported many of self-determination theory.

The article would employ spiral model of conflict proposed by Robert Jervis as a theoretical framework to scrutinize contemporary US and Chinese contemporary competition. As a result, this paper shows how threat assessment could trigger a spiral of conflict through state’s tendency to overestimate threat level and its failure to perceive that defensive behavior can be interpreted as offensive by the belligerent. Based on this analysis, the probability of conflicts can be reduced as each country tries to comprehend motivations that drive other behavior, perceptions and reactions that might arise as a result of the strategic empathy.

The aim of this study was to assess the effect of a supportive educational intervention developed based on the Orem's self-care theory on the self-care ability of patients with myocardial infarction. Patients with cardiovascular disease suffer from the lack of knowledge about the disease and consequently are not able to fulfil their own self-care needs. This was a randomised controlled trial conducted in 2012. We recruited a random sample of 66 patients with myocardial infarction who had been recently discharged from coronary care unit. The study setting was two university hospitals located in Khorasan, Iran. Patients were randomly allocated to either the experimental or the control groups. Patients in the experimental group received education, support, and counselling while patients in the control group received no intervention. We employed a demographic questionnaire and the Myocardial Infarction Self-Care Ability Questionnaire for data collection and spss version 16.00 for data analysis. After the study, patients in the experimental group had higher levels of self-care knowledge, motivation and skills compared to the prestudy readings and the control group. The supportive educational intervention developed based on the Orem's self-care theory can improve nonhospitalised patients' self-care ability and positively affect public health outcomes. Consequently, using the developed programme for providing follow-up care to nonhospitalised patients is recommended. Having the ability to develop caring systems based on the nursing theories is a prerequisite to standard nursing practice. Identifying patients' educational needs is a fundamental prerequisite to patient education. Our findings revealed that the supportive educational intervention developed based on the Orem's self-care theory can help health care providers identify and fulfil patients' self-care needs. © 2015 John Wiley & Sons Ltd.
Rational speculative bubbles: A critical view

Full Text Available According to the theory of rational bubbles, the bubble is present whenever asset prices progressively diverge from their fundamental value, which occurs because agents expect that asset prices will continue to grow exponentially (self-fulfilling prophecies far in the future and consistently, which promises the realization of ever larger capital gains. In our opinion, the basic shortcoming of this theory refers to the assumption that all market agents are perfectly informed and rational and, accordingly, form homogeneous expectations. The model does not explain decision-making processes or expectation formation, nor does it detect potential psychological and institutional factors that might significantly influence decision making processes and market participants’ reactions to news. Since assumptions of the model critically determine its validity, we conclude that comprehensiveness of the rational bubble model is, to put it mildly, limited.

Neurologists are often asked to define prognosis in comatose patients. However, comatose patients following cardiac arrest are usually cared for by cardiologists or intensivists, and it is their approach that will influence decisions regarding withdrawal of life-sustaining interventions (WLSI). We observed that factors leading to these decisions vary across specialties and considered whether they could result in self-fulfilling prophecies and early WLSI. We conducted a hypothesis-generating qualitative study to identify factors used by non-neurologists to define prognosis in these patients and construct an explanatory model for how early WLSI might occur. This was a single-center qualitative study of intensivists caring for cardiac arrest patients with hypoxic-ischemic coma. Thirty attending physicians (n = 16) and fellows (n = 14) from cardiac (n = 8), medical (n = 6), surgical (n = 10), and neuro (n = 6) intensive care units underwent semi-structured interviews. Interview transcripts were analyzed using grounded theory techniques. We found three components of early WLSI among non-neurointensivists: (1) development of fixed negative opinions; (2) early framing of poor clinical pictures to families; and (3) shortened windows for judging recovery potential. In contrast to neurointensivists, non-neurointensivists' negative opinions were frequently driven by patients' lack of consciousness and cardiopulmonary resuscitation circumstances. Both groups were influenced by age and comorbidities. The results demonstrate that factors influencing prognostication differ across specialties. Some differ from those recommended by published guidelines and may lead to self-fulfilling prophecies and early WLSI. Better understanding of this framework would facilitate educational interventions to mitigate this phenomenon and its implications on patient care.

A pattern theory of self.

Gallagher, Shaun

2013-01-01

I argue for a pattern theory of self as a useful way to organize an interdisciplinary approach to discussions of what constitutes a self. According to the pattern theory, a self is constituted by a number of characteristic features or aspects that may include minimal embodied, minimal experiential, affective, intersubjective, psychological/cognitive, narrative, extended, and situated aspects. A pattern theory of self helps to clarify various interpretations of self as compatible or commensurable instead of thinking them in opposition, and it helps to show how various aspects of self may be related across certain dimensions. I also suggest that a pattern theory of self can help to adjudicate (or at least map the differences) between the idea that the self correlates to self-referential processing in the cortical midline structures of the brain and other narrower or wider conceptions of self.

Alcohol myopia theory posits that alcohol consumption attenuates information processing capacity, and that expectancy beliefs together with intake level are responsible for experiences in myopic effects (relief, self-inflation, and excess). Adults (N=413) averaging 36.39 (SD=13.02) years of age completed the Comprehensive Effects of Alcohol questionnaire at baseline, followed by alcohol use measures (frequency and quantity) and the Alcohol Myopia Scale one month later. Three structural equation models based on differing construct manifestations of alcohol expectancies served to longitudinally forecast alcohol use and myopia. In Model 1, overall expectancy predicted greater alcohol use and higher levels of all three myopic effects. In Model 2, specifying separate positive and negative expectancy factors, positive but not negative expectancy predicted greater use. Furthermore, positive expectancy and use explained higher myopic relief and higher self-inflation, whereas positive expectancy, negative expectancy, and use explained higher myopic excess. In Model 3, the seven specific expectancy subscales (sociability, tension reduction, liquid courage, sexuality, cognitive and behavioral impairment, risk and aggression, and self-perception) were simultaneously specified as predictors. Tension reduction expectancy, sexuality expectancy, and use contributed to higher myopic relief; sexuality expectancy and use explained higher myopic self-inflation; and risk and aggression expectancy and use accounted for higher myopic excess. Across all three predictive models, the total variance explained ranged from 12 to 19% for alcohol use, 50 to 51% for relief, 29 to 34% for self-inflation, and 32 to 35% for excess. Findings support that the type of alcohol myopia experienced is a concurrent function of self-fulfilling alcohol prophecies and drinking levels. The interpreted measurement manifestation of expectancy yielded different prevention implications. Copyright © 2017 Elsevier

The role of the political prophecy of the Boer “Nostradamus” in the formation of the ideology of the conservative right in South Africa

2016-02-01

Full Text Available This article analyzes the influence of the prophet Siner Van Rensburg and later interpreters of his visions on creation of the Boer and Afrikaner national identity in the Republic of South Africa from the start of the 20th century until today. The work of the prophet and his disciples is viewed in the light of important historical events and contemporary political circumstances. Through the interpretation of the political instrumentalization of this prophecy, the mechanism of the making of and functioning of political foresight is demonstrated. This is also applicable to the opus of numerous other seers all over the world. A critical overview of important works of authors dealing with this issue is given, as well as a theoretical basis for planned future research. The primary role of the prophecy is, inthis paper, not identified as the divination of future events but as the ideological reinterpretation of the past and the present through the prism of determinism and facing social change in times of crisis, as well as their negation. Thus, the supposed prophecies become an acceptable place to express socially unacceptable attitudes and unrealized political wishes, goals and ambitions.

Smith, Geoffrey P; Williams, Theresa M

2017-01-01

There has been increasing reliance on policy directives as instruments for shaping clinical practice in health care, despite it being widely recognized that there is a significant translation gap between clinical policy and its implementation. Self-Determination Theory, a widely researched and empirically validated theory of human needs' fulfilment and motivation, offers a potentially valuable theoretical framework for understanding not only why the current policy environment has not led to the anticipated improvement in the quality and safety of clinical care but, importantly, also provides guidance about how organizations can create an environment that can nurture behavioural change in the workforce. We describe an alternative approach to clinical policy-making underpinned by Self-Determination Theory, which we believe has broad application for the science of clinical implementation theory.
Self-dual gauge theories

International Nuclear Information System (INIS)

Zet, G.

2002-01-01

The self-duality equations are important in gauge theories because they show the connection between gauge models with internal symmetry groups and gauge theory of gravity. They are differential equations of the first order and it is easier to investigate the solutions for different particular configurations of the gauge fields and of space-times.One of the most important property of the self-duality equations is that they imply the Yang-Mills field equations. In this paper we will prove this property for the general case of a gauge theory with compact Lie group of symmetry over a 4-dimensional space-time manifold. It is important to remark that there are 3m independent self-duality equations (of the first order) while the number of Yang-Mills equations is equal to 4m, where m is the dimension of the gauge group. Both of them have 4m unknown functions which are the gauge potentials A μ a (x), a = 1, 2, ....,m; μ = 0, 1, 2, 3. But, we have, in addition, m gauge conditions for A μ a (x), (for example Coulomb, Lorentz or axial gauge) which together with the selfduality equation constitute a system of 4m equations. The Bianchi identities for the self-dual stress tensor F μν a coincide with the Yang-Mills equations and do not imply therefore supplementary conditions. We use the axial gauge in order to obtain the self duality equations for a SU(2) gauge theory over a curved space-time. The compatibility between self-duality and Yang-Mills equations is studied and some classes of solutions are obtained. In fact, we will write the Einstein-Yang-Mills equations and we will analyse only the Yang-Mills sector. The Einstein equations can not be obtained of course from self-duality. They should be obtained if we would consider a gauge theory having P x SU(2) as symmetry group, where P is the Poincare group. More generally, a gauge theory of N-extended supersymmetry can be developed by imposing the self-duality condition. (author)

OLD TESTAMENT PROPHECIES AND ESCHATOLOGICAL IMAGERY IN SERGEI YESENIN'S POETRY (1918–1919

Directory of Open Access Journals (Sweden)

Mariya Aleksandrovna Solov'eva

2014-11-01

Full Text Available The article discusses the features of the poetics of Yesenin lyrics of 1918-1919. Poems of this period form a single metatekst about the end of the time, and the coming of the Day of Judgment. Th e research shows that the disclosure of eschatology theme by the poet exhibits characteristic features of the artistic world of S. A. Yesenin. The most important source of Yesenin's poetic imagery is the experience of Orthodox worship gained by him in childhood and adolescence. Liturgical foundations of Yesenin's artistic thinking implemented in diff erent planes of the content of poetics throughout the career of the poet. In the "little poems" and poems of 1918-1919 the structure and symbolism of the liturgical text is presented. Yesenin uses quotes and paraphrases hymns and texts of Scripture; liturgical symbols and actions of church utensils, iconographic images are refl ected in his poetry. Th e content and the relationship of poetic images and symbols, the interplay of these images are in compliance with the poetics of liturgical texts. A complex semiotic structure of worship is reflected in the poetry in the form of correlations of the New Testament and the Old Testament prophecies, combined with various biblical images and motifs. A theme of Old Testament prophecy is reproduced in liturgical discourse. In the development of eschatological themes the characters of prophets also form an additional scope of meanings associated with the spirit of the revolutionary events: the prophets becomes representatives of the common people, the spokesmen of the national spiritual experience. The poetic text had borne the additional connotations with biblical stories on the ministry of the prophets.

Job satisfaction of people with intellectual disabilities: the role of basic psychological need fulfillment and workplace participation.

Science.gov (United States)

Akkerman, Alma; Kef, Sabina; Meininger, Herman P

2018-05-01

Knowledge on what contributes to job satisfaction of people with intellectual disabilities is limited. Using self-determination theory, we investigated whether fulfillment of basic psychological needs (i.e., autonomy, relatedness, competence) affected job satisfaction, and explored associations between workplace participation, need fulfillment and job satisfaction. A total of 117 persons with intellectual disabilities, recruited from a Dutch care organization, were interviewed on need fulfillment at work and job satisfaction. Data on workplace participation was obtained from staff. Questionnaires were based on well-established instruments. Basic psychological need fulfillment predicted higher levels of job satisfaction. Level of workplace participation was not associated with need fulfillment or job satisfaction. Allowing workers with intellectual disabilities to act with a sense of volition, feel effective, able to meet challenges, and connected to others is essential and contributes to job satisfaction. It is needed to pay attention to this, both in selection and design of workplaces and in support style. Implications for rehabilitation Knowledge on factors that contribute to job satisfaction is necessary to improve employment situations and employment success of people with intellectual disabilities. In order to achieve job satisfaction, it is essential that workplaces allow for fulfillment of the basic psychological needs for autonomy, relatedness, and competence of people with intellectual disabilities. People with intellectual disabilities are able to report on their needs and satisfaction, and it is important that their own perspective is taken into account in decisions regarding their employment situation.

What is the function of self-esteem? We classified relevant theoretical work into 3 perspectives. The cultural norm-fulfillment perspective regards self-esteem a result of adherence to cultural norms. The interpersonal-belonging perspective regards self-esteem as a sociometer of interpersonal belonging. The getting-ahead perspective regards self-esteem as a sociometer of getting ahead in the social world, while regarding low anxiety/neuroticism as a sociometer of getting along with others. The 3 perspectives make contrasting predictions on the relation between the Big Five personality traits and self-esteem across cultures. We tested these predictions in a self-report study (2,718,838 participants from 106 countries) and an informant-report study (837,655 informants from 64 countries). We obtained some evidence for cultural norm fulfillment, but the effect size was small. Hence, this perspective does not satisfactorily account for self-esteem's function. We found a strong relation between Extraversion and higher self-esteem, but no such relation between Agreeableness and self-esteem. These 2 traits are pillars of interpersonal belonging. Hence, the results do not fit the interpersonal-belonging perspective either. However, the results closely fit the getting-ahead perspective. The relation between Extraversion and higher self-esteem is consistent with this perspective, because Extraversion is the Big Five driver for getting ahead in the social world. The relation between Agreeableness and lower neuroticism is also consistent with this perspective, because Agreeableness is the Big Five driver for getting along with others.

This survey also links with the Equity Premium Puzzle. It may be explained by the fact that many market participants use historical data and advice from textbooks and finance professors. Consequently, ex-ante equity premia have been high, most market prices have been consistently undervalued, and the ex-post risk premia has been also high. Many investors use historical data and textbook prescriptions to estimate the required and the expected equity premium, the undervaluation and the high ex-post risk premium are self fulfilling prophecies.
Understanding Self-Controlled Motor Learning Protocols through the Self-Determination Theory.

2012-01-01

The purpose of the present review was to provide a theoretical understanding of the learning advantages underlying a self-controlled practice context through the tenets of the self-determination theory (SDT). Three micro-theories within the macro-theory of SDT (Basic psychological needs theory, Cognitive Evaluation Theory, and Organismic Integration Theory) are used as a framework for examining the current self-controlled motor learning literature. A review of 26 peer-reviewed, empirical studies from the motor learning and medical training literature revealed an important limitation of the self-controlled research in motor learning: that the effects of motivation have been assumed rather than quantified. The SDT offers a basis from which to include measurements of motivation into explanations of changes in behavior. This review suggests that a self-controlled practice context can facilitate such factors as feelings of autonomy and competence of the learner, thereby supporting the psychological needs of the learner, leading to long term changes to behavior. Possible tools for the measurement of motivation and regulation in future studies are discussed. The SDT not only allows for a theoretical reinterpretation of the extant motor learning research supporting self-control as a learning variable, but also can help to better understand and measure the changes occurring between the practice environment and the observed behavioral outcomes.

Benefits of transformational behaviors for leaders: A daily investigation of leader behaviors and need fulfillment.

Lanaj, Klodiana; Johnson, Russell E; Lee, Stephanie M

2016-02-01

Although a large body of work has examined the benefits of transformational leadership, this work has predominantly focused on recipients of such behaviors. Recent research and theory, however, suggest that there are also benefits for those performing behaviors reflective of transformational leadership. Across 2 experience-sampling studies, we investigate the effects of such behaviors on actors' daily affective states. Drawing from affective events theory and self-determination theory we hypothesize and find that engaging in behaviors reflective of transformational leadership is associated with improvement in actors' daily affect, more so than engaging in behaviors reflective of transactional, consideration, initiating structure, and participative leadership. Behaviors reflective of transformational leadership improved actors' affect in part by fulfilling their daily needs. Furthermore, extraversion and neuroticism moderated these effects such that extraverts benefitted less whereas neurotics benefitted more from these behaviors in terms of affective changes. We consider the theoretical and practical implications of these findings and offer directions for future research. (c) 2016 APA, all rights reserved).

This research was part of a larger mixed-methods study examining culture, distress, and help seeking. We surveyed 209 Japanese women living in the United States recruited from clinic and community-based sites, and carried out semi-structured ethnographic interviews with a highly distressed subsample of 25 Japanese. Analytic Ethnography revealed that women described themselves as a “self-in-context,” negotiating situations using protective resources or experiencing risk exposure. Women experienced quality of life (QOL) when they were successful. However, a related goal of achieving Ikigai (or purpose in life) was differentiated from QOL, and was defined as an ongoing process of searching for balance between achieving social and individual fulfillment. Our resulting hypothetical model suggested that symptom level would be related to risk and protective factors (tested for the full sample) and to specific risk and protective phenomenon (tested in the distressed subsample). The t tests in the full sample found that women who were above threshold for depressive symptoms (n = 26) had higher social stressor and lower social support means. Women who were above the threshold for physical symptoms (n = 99) had higher social stressor means. Analysis of the interviewed subsample found that low self-validation and excessive responsibilities were related to high physical symptoms. We conclude that perceived lack of balance between culturally defined, and potentially opposing, markers of success can create a stressful dilemma for first-generation immigrant Japanese women, requiring new skills to achieve balance. Perceptions of health, as well as illness, are part of complex culturally based interpretations that have implications for intervention for immigrant Japanese women living in the United States.

Quantum Theories of Self-Localization

Science.gov (United States)

Bernstein, Lisa Joan

In the classical dynamics of coupled oscillator systems, nonlinearity leads to the existence of stable solutions in which energy remains localized for all time. Here the quantum-mechanical counterpart of classical self-localization is investigated in the context of two model systems. For these quantum models, the terms corresponding to classical nonlinearities modify a subset of the stationary quantum states to be particularly suited to the creation of nonstationary wavepackets that localize energy for long times. The first model considered here is the Quantized Discrete Self-Trapping model (QDST), a system of anharmonic oscillators with linear dispersive coupling used to model local modes of vibration in polyatomic molecules. A simple formula is derived for a particular symmetry class of QDST systems which gives an analytic connection between quantum self-localization and classical local modes. This formula is also shown to be useful in the interpretation of the vibrational spectra of some molecules. The second model studied is the Frohlich/Einstein Dimer (FED), a two-site system of anharmonically coupled oscillators based on the Frohlich Hamiltonian and motivated by the theory of Davydov solitons in biological protein. The Born-Oppenheimer perturbation method is used to obtain approximate stationary state wavefunctions with error estimates for the FED at the first excited level. A second approach is used to reduce the first excited level FED eigenvalue problem to a system of ordinary differential equations. A simple theory of low-energy self-localization in the FED is discussed. The quantum theories of self-localization in the intrinsic QDST model and the extrinsic FED model are compared.
The Stereotype-Matching Effect: Greater Influence on Functioning When Age Stereotypes Correspond to Outcomes

Older individuals assimilate, and are targeted by, contradictory positive and negative age stereotypes. It was unknown whether the influence of stereotype valence is stronger when the stereotype content corresponds to the outcome domain. We randomly assigned older individuals to either positive-cognitive, negative-cognitive, positive-physical, or negative-physical subliminal-age-stereotype groups and assessed cognitive and physical outcomes. As predicted, when the age stereotypes corresponded to the outcome domains, their valence had a significantly greater impact on cognitive and physical performance. This suggests that if a match occurs, it is more likely to generate expectations that become self-fulfilling prophecies. PMID:19290757

Raabe, Johannes; Readdy, Tucker

2016-01-01

Cheerleading is one of the fastest-growing sports in the United States. Members of spirit squads play an undeniable role in developing a university's athletic image, and participation in cheer has the potential to affect adolescents and young adults in a positive manner. Yet, cheerleaders also encounter stereotypes, constant trivialization, and a relative lack of external rewards. Given this complex contextual and situational environment, the current investigation was designed to better understand why people are motivated to participate in collegiate cheerleading. More specifically, guided by the premises of self-determination theory (SDT), this study explored motivational profiles and basic psychological need satisfaction (i.e., competence, autonomy, and relatedness) across different contexts and situations that comprise the collegiate cheerleading environment. Consistent with established guidelines for qualitative inquiry, 12 collegiate cheerleaders were interviewed at 3 separate time points during the course of 1 academic semester. Deductive and inductive qualitative analyses yielded 3 higher-order themes, including: (a) context specificity of basic psychological need satisfaction, (b) contribution of performance to motivation, and (c) occurrences of intrinsic motivation. These results highlighted the complex nature of motivation and basic psychological need fulfillment, including a potential synergism between relatedness and competence fulfillment as well as an influence of academics on sport motivation. These nuances add to the theoretical understanding of SDT and offer valuable insight for coaches and sport psychology professionals working with collegiate spirit squads.
Similarities between Prescott Lecky's theory of self-consistency and Carl Rogers' self-theory.

Science.gov (United States)

Merenda, Peter F

2010-10-01

The teachings of Prescott Lecky on the self-concept at Columbia University in the 1920s and 1930s and the posthumous publications of his book on self-consistency beginning in 1945 are compared with the many publications of Carl Rogers on the self-concept beginning in the early 1940s. Given that Rogers was a graduate student at Columbia in the 1920s and 1930s, the striking similarities between these two theorists, as well as claims attributed to Rogers by Rogers' biographers and writers who have quoted Rogers on his works relating to self-theory, strongly suggest that Rogers borrowed from Lecky without giving him the proper credit. Much of Rogers' writings on the self-concept included not only terms and concepts which were original with Lecky, but at times these were actually identical.
A behavior-analytic critique of Bandura's self-efficacy theory

Science.gov (United States)

Biglan, Anthony

1987-01-01

A behavior-analytic critique of self-efficacy theory is presented. Self-efficacy theory asserts that efficacy expectations determine approach behavior and physiological arousal of phobics as well as numerous other clinically important behaviors. Evidence which is purported to support this assertion is reviewed. The evidence consists of correlations between self-efficacy ratings and other behaviors. Such response-response relationships do not unequivocally establish that one response causes another. A behavior-analytic alternative to self-efficacy theory explains these relationships in terms of environmental events. Correlations between self-efficacy rating behavior and other behavior may be due to the contingencies of reinforcement that establish a correspondence between such verbal predictions and the behavior to which they refer. Such a behavior-analytic account does not deny any of the empirical relationships presented in support of self-efficacy theory, but it points to environmental variables that could account for those relationships and that could be manipulated in the interest of developing more effective treatment procedures.

Prophecy and Doubt in Just Above My Head

Directory of Open Access Journals (Sweden)

Christopher Z. Hobson

2015-09-01

Full Text Available Written in the aftermath of the civil rights era’s expansive hopes, James Baldwin’s last novel, Just Above My Head (1979, examines a fundamental issue, the choice between hope and skepticism, or prophecy and doubt. Baldwin approaches this issue by questioning two cornerstone ideas of his fiction, the need for prophetic art and this art’s focus on anticipating a renovated society, often pictured in terms adapted from apocalyptic biblical texts and Gospel music lyrics. Just Above My Head is Baldwin’s fullest presentation of this kind of art and its linkage to apocalyptic hopes. He dramatizes these ideas in the art of his Gospel singer protagonist, particularly in a climactic scene of artistic dedication whose Gospel lyric envisions “tearing down the kingdom of this world.” Yet Baldwin also unsparingly questions these same ideas through plot and the blues-inflected skeptical-tragic consciousness of his narrator. Responding to a 1970s moment when hopes for transcendent justice seemed passé, Just Above My Head’s unique contribution is not to try to resolve the ideas it counterposes, but to face both the possible falseness of prophetic hope and our continuing need for it, and to present the necessity for choice in a final dream that holds the key to the novel’s meaning. In presenting this issue through a sustained double-voiced narrative that reexamines its author’s artistic practice and raises fundamental choices in outlook and conduct, Just Above My Head evidences the continuing artistic vitality of Baldwin’s late fiction.

Rediscovering Rogers’s Self Theory and Personality

2015-12-01

Full Text Available Abstract This study examined the self theory of Carl Rogers in depth. There are some important concepts illuminated well, considering one's personality development. Its main focus was positive regard, self-worth and actualizing tendency, proposed by Rogers. To explain them in brief, positive regard was studied through self-image, ideal self and congruence. Self-worth is described as conditional and unconditional to cope with challenges in life, tolerate failures and sadness at times. Actualizing tendency was expounded into fully functioning or self-actualizing. These all concepts indicated that having a tendency on human behavior and concentrating on the capacity of individuals to think intentionally and soundly, to control their biological urges, are significantly main elements to evaluate one’s self. Therefore, in the humanistic perspective, individuals have the opportunity and will to change their states of mind and behavior. This study might be a guide to some certain aspect of self related studies for other researchers to benefit accordingly and also to develop a new scale related to self using Rogers’s theory.

The close relationship between prophecy and dissent is clear and well-researched. The example of the sixteenth-century charismatic Hendrik Niclaes, who wrote prophetical texts under the cryptonym HN, simply seems to be another case in point.

Prophecy, patriarchy, and violence in the early modern household: the revelations of Anne Wentworth.

Science.gov (United States)

Johnston, Warren

2009-10-01

In 1676 the apostate Baptist prophet Anne Wentworth (1629/30-1693?) published "A True Account of Anne Wentworths Being Cruelly, Unjustly, and Unchristianly Dealt with by Some of Those People called Anabaptists," the first in a series of pamphlets that would continue to the end of the decade. Orignially a member of a London Baptist church, Wentworth left the congregation and eventually her own home after her husband used physical force to stop her writing and prophesying. Yet Wentworth persisted in her "revelations." These prophecies increasingly focused on her response to those who were trying to stop her efforts, especially within her own household. This article examines Wentworth's writings as an effort by an early modern woman, using arguments of spiritual agency, to assert ideas about proper gender roles and household responsibilities to denounce her husband and rebut those who criticized and attempted to suppress her.
Defensiveness versus remediation: self-theories and modes of self-esteem maintenance.

Nussbaum, A David; Dweck, Carol S

2008-05-01

How people maintain and repair their self-esteem has been a topic of widespread interest. In this article, the authors ask, What determines whether people will use direct, remedial actions, or defensive actions? In three studies, they tested the hypothesis that a belief in fixed intelligence (entity theory) would produce defensiveness, whereas a belief in improvable intelligence (incremental theory) would foster remediation. In each study, participants assigned to the entity condition opted for defensive self-esteem repair (downward comparison in Studies 1 and 3; a tutorial on already mastered material in Study 2), but those in the incremental condition opted for self-improvement (upward comparison in Studies 1 and 3; a tutorial on unmastered material in Study 2). Experiment 3 also linked these strategies to self-esteem repair; remedial strategies were the most effective in recovering lost self-esteem for those in the incremental condition, whereas defensive strategies were most effective for those in the entity condition.

Self-determination theory and the welfare of employees

Directory of Open Access Journals (Sweden)

Ranđelović Kristina M.

2013-01-01

Full Text Available The objective of this article is to give an account of the psychological welfare of employees in the context of self-determination theory. SDT represents an approach to human motivation and personality that uses traditional empirical methods which make clear the importance of development of human innate abilities for personal development, integration and self-regulation. Self-determination theory emphasizes that welfare is an direct function with the satisfaction of basic psychological needs. According to the above mentioned theory self actualization (eudemonia represents the key aspect of psychological welfare. Namely, SDT aims to explain what it means to actualize oneself and how to schive that. The researches within self-determination theory are focused on the factors that allow or prevent psychological grouth, integrity and welfare. SDT is a theory with great prospect and it allows us not only to understand better the psychological processes in many aspects of use (sport, work, parenthood, education, etc. but also to direct programs and interventions that improve the circumstances in which people live. The theory has recently been applied in health-working psychology and few empirical findings have given support to its fundamental premises. SDT is a consistant theory that can be tested, it is applicable in almost all spheres of life (family, school system, health care, work, relationships among people ect. and it gives a broad spectrum of possible problems to research. It not only offers different social environments and his welfare, but the theory also offers directives how to improve the conditions in witch people live and work. The organizational context that allows the possibility to choose, make autonomous decisions, clear explanations of certain work assignments, as well as the appreciation of feelings and attitudes of the employees will bring about greater satisfaction of the innate needs for grouth.

Animal spirits, competitive markets, and endogenous growth

Miyazaki, Kenji

2013-10-01

This paper uses a simple model with an endogenous discount rate and linear technology to investigate whether a competitive equilibrium has a higher balanced growth path (BGP) than the social planning solution and whether the BGP is determinate or indeterminate. The implications are as follows. To start with, people with an instinct to compare themselves with others possess an endogenous discount rate. In turn, this instinct affects the economic growth rate in a competitive market economy. The competitive market economy also sometimes achieves higher economic growth than a social planning economy. However, the outcomes of market economy occasionally fluctuate because of the presence of the self-fulfilling prophecy or animal spirits.
On relativistic irreducible quantum fields fulfilling CCR

Let phi be a relativistic scalar field fulfilling canonical commutation relations (CCR). Furthermore it is assumed that the time zero fields and momenta form an irreducible set. Based on estimates given by Herbst [I. W. Herbst, J. Math. Phys. 17, 1210 (1976)], and by methods developed by Powers [R. T. Powers, Commun. Math. Phys. 4, 145 (1967)], it is shown that phi has to be a free field in n>3 space dimensions. For n = 3 (resp. n = 2) restrictions that look similar to the restriction in a formal :phi 4 : 3 /sub +/ 1 (resp. :phi 6 : 2 /sub +/ 1 ) theory are obtained

Implicit theories about willpower predict self-regulation and grades in everyday life.

Science.gov (United States)

Job, Veronika; Walton, Gregory M; Bernecker, Katharina; Dweck, Carol S

2015-04-01

Laboratory research shows that when people believe that willpower is an abundant (rather than highly limited) resource they exhibit better self-control after demanding tasks. However, some have questioned whether this "nonlimited" theory leads to squandering of resources and worse outcomes in everyday life when demands on self-regulation are high. To examine this, we conducted a longitudinal study, assessing students' theories about willpower and tracking their self-regulation and academic performance. As hypothesized, a nonlimited theory predicted better self-regulation (better time management and less procrastination, unhealthy eating, and impulsive spending) for students who faced high self-regulatory demands. Moreover, among students taking a heavy course load, those with a nonlimited theory earned higher grades, which was mediated by less procrastination. These findings contradict the idea that a limited theory helps people allocate their resources more effectively; instead, it is people with the nonlimited theory who self-regulate well in the face of high demands.

Interfacial self-healing of nanocomposite hydrogels: Theory and experiment

Science.gov (United States)

Wang, Qiming; Gao, Zheming; Yu, Kunhao

2017-12-01

Polymers with dynamic bonds are able to self-heal their fractured interfaces and restore the mechanical strengths. It is largely elusive how to analytically model this self-healing behavior to construct the mechanistic relationship between the self-healing properties (e.g., healed interfacial strength and equilibrium healing time) and the material compositions and healing conditions. Here, we take a self-healable nanocomposite hydrogel as an example to illustrate an interfacial self-healing theory for hydrogels with dynamic bonds. In the theory, we consider the free polymer chains diffuse across the interface and reform crosslinks to bridge the interface. We analytically reveal that the healed strengths of nanocomposite hydrogels increase with the healing time in an error-function-like form. The equilibrium self-healing time of the full-strength recovery decreases with the temperature and increases with the nanoparticle concentration. We further analytically reveal that the healed interfacial strength decreases with increasing delaying time before the healing process. The theoretical results quantitatively match with our experiments on nanosilica hydrogels, and also agree well with other researchers' experiments on nanoclay hydrogels. We expect that this theory would open promising avenues for quantitative understanding of the self-healing mechanics of various polymers with dynamic bonds, and offer insights for designing high-performance self-healing polymers.
MOTIVATION INTERNALIZATION AND SIMPLEX STRUCTURE IN SELF-DETERMINATION THEORY.

Science.gov (United States)

Ünlü, Ali; Dettweiler, Ulrich

2015-12-01

Self-determination theory, as proposed by Deci and Ryan, postulated different types of motivation regulation. As to the introjected and identified regulation of extrinsic motivation, their internalizations were described as "somewhat external" and "somewhat internal" and remained undetermined in the theory. This paper introduces a constrained regression analysis that allows these vaguely expressed motivations to be estimated in an "optimal" manner, in any given empirical context. The approach was even generalized and applied for simplex structure analysis in self-determination theory. The technique was exemplified with an empirical study comparing science teaching in a classical school class versus an expeditionary outdoor program. Based on a sample of 84 German pupils (43 girls, 41 boys, 10 to 12 years old), data were collected using the German version of the Academic Self-Regulation Questionnaire. The science-teaching format was seen to not influence the pupils' internalization of identified regulation. The internalization of introjected regulation differed and shifted more toward the external pole in the outdoor teaching format. The quantification approach supported the simplex structure of self-determination theory, whereas correlations may disconfirm the simplex structure.
The role of self-determination theory and cognitive evaluation theory in home education

Directory of Open Access Journals (Sweden)

Gina Riley

2016-12-01

Full Text Available This article explores the theories of Self-Determination, Cognitive Evaluation, and Intrinsic Motivation as it applies to home education. According to Self-Determination Theory, intrinsic motivation is innate. However, the maintenance and enhancement of intrinsic motivation depends upon the social and environmental conditions surrounding the individual. Deci and Ryan’s Cognitive Evaluation Theory specifically addresses the social and environmental factors that facilitate versus undermine intrinsic motivation and points to three significant psychological needs that must be present in the individual in order to foster self-motivation. These needs are competence, autonomy, and relatedness. Because of curriculum and time constraints, intrinsic motivation may be difficult to facilitate within the traditional classroom. This loss of intrinsic motivation for learning prompts some parents to homeschool their children. One of the most impressive strengths of home education lies in the fact that in many cases, the entire process revolves around a child’s intrinsic motivation to learn.

The Situation-Specific Theory of Heart Failure Self-Care: Revised and Updated.

Science.gov (United States)

Riegel, Barbara; Dickson, Victoria Vaughan; Faulkner, Kenneth M

2016-01-01

Since the situation-specific theory of heart failure (HF) self-care was published in 2008, we have learned much about how and why patients with HF take care of themselves. This knowledge was used to revise and update the theory. The purpose of this article was to describe the revised, updated situation-specific theory of HF self-care. Three major revisions were made to the existing theory: (1) a new theoretical concept reflecting the process of symptom perception was added; (2) each self-care process now involves both autonomous and consultative elements; and (3) a closer link between the self-care processes and the naturalistic decision-making process is described. In the revised theory, HF self-care is defined as a naturalistic decision-making process with person, problem, and environmental factors that influence the everyday decisions made by patients and the self-care actions taken. The first self-care process, maintenance, captures those behaviors typically referred to as treatment adherence. The second self-care process, symptom perception, involves body listening, monitoring signs, as well as recognition, interpretation, and labeling of symptoms. The third self-care process, management, is the response to symptoms when they occur. A total of 5 assumptions and 8 testable propositions are specified in this revised theory. Prior research illustrates that all 3 self-care processes (ie, maintenance, symptom perception, and management) are integral to self-care. Further research is greatly needed to identify how best to help patients become experts in HF self-care.

Specifically, the level of congruence between identities and the self is ...
Early prediction of coma recovery after cardiac arrest with blinded pupillometry.

2017-06-01

Prognostication studies on comatose cardiac arrest (CA) patients are limited by lack of blinding, potentially causing overestimation of outcome predictors and self-fulfilling prophecy. Using a blinded approach, we analyzed the value of quantitative automated pupillometry to predict neurological recovery after CA. We examined a prospective cohort of 103 comatose adult patients who were unconscious 48 hours after CA and underwent repeated measurements of quantitative pupillary light reflex (PLR) using the Neurolight-Algiscan device. Clinical examination, electroencephalography (EEG), somatosensory evoked potentials (SSEP), and serum neuron-specific enolase were performed in parallel, as part of standard multimodal assessment. Automated pupillometry results were blinded to clinicians involved in patient care. Cerebral Performance Categories (CPC) at 1 year was the outcome endpoint. Survivors (n = 50 patients; 32 CPC 1, 16 CPC 2, 2 CPC 3) had higher quantitative PLR (median = 20 [range = 13-41] vs 11 [0-55] %, p < 0.0001) and constriction velocity (1.46 [0.85-4.63] vs 0.94 [0.16-4.97] mm/s, p < 0.0001) than nonsurvivors. At 48 hours, a quantitative PLR < 13% had 100% specificity and positive predictive value to predict poor recovery (0% false-positive rate), and provided equal performance to that of EEG and SSEP. Reduced quantitative PLR correlated with higher serum neuron-specific enolase (Spearman r = -0.52, p < 0.0001). Reduced quantitative PLR correlates with postanoxic brain injury and, when compared to standard multimodal assessment, is highly accurate in predicting long-term prognosis after CA. This is the first prognostication study to show the value of automated pupillometry using a blinded approach to minimize self-fulfilling prophecy.

Induced boson self couplings in four-fermion and Yukawa theories

International Nuclear Information System (INIS)

Tamvakis, K.K.

1978-01-01

Theories of self-interacting fermion fields are expanded in a mean field expansion in terms of boson collective variables. Divergences can be absorbed in a renormalized mass and a renormalized Yukawa-type coupling to all orders in the mean field expansion. The cubic and quartic collective boson self-couplings required by renormalization are fixed in terms of the renormalized Yukawa coupling. This fixing is demonstrated by use of the Callan-Symanzik equations. These theories are formally equivalent to Yukawa-type theories, expanded the same way, with the boson self-couplings constrained to be functions of the Yukawa coupling

Towards a unification of the hierarchical reference theory and the self-consistent Ornstein-Zernike approximation.

Science.gov (United States)

Reiner, A; Høye, J S

2005-12-01

The hierarchical reference theory and the self-consistent Ornstein-Zernike approximation are two liquid state theories that both furnish a largely satisfactory description of the critical region as well as phase coexistence and the equation of state in general. Furthermore, there are a number of similarities that suggest the possibility of a unification of both theories. As a first step towards this goal, we consider the problem of combining the lowest order gamma expansion result for the incorporation of a Fourier component of the interaction with the requirement of consistency between internal and free energies, leaving aside the compressibility relation. For simplicity, we restrict ourselves to a simplified lattice gas that is expected to display the same qualitative behavior as more elaborate models. It turns out that the analytically tractable mean spherical approximation is a solution to this problem, as are several of its generalizations. Analysis of the characteristic equations shows the potential for a practical scheme and yields necessary conditions that any closure to the Ornstein-Zernike relation must fulfill for the consistency problem to be well posed and to have a unique differentiable solution. These criteria are expected to remain valid for more general discrete and continuous systems, even if consistency with the compressibility route is also enforced where possible explicit solutions will require numerical evaluations.

Analysis of self-consistency effects in range-separated density-functional theory with Møller-Plesset perturbation theory

DEFF Research Database (Denmark)

Fromager, Emmanuel; Jensen, Hans Jørgen Aagaard

2011-01-01

Range-separated density-functional theory combines wave function theory for the long-range part of the two-electron interaction with density-functional theory for the short-range part. When describing the long-range interaction with non-variational methods, such as perturbation or coupled......-cluster theories, self-consistency effects are introduced in the density functional part, which for an exact solution requires iterations. They are generally assumed to be small but no detailed study has been performed so far. Here, the authors analyze self-consistency when using Møller-Plesset-type (MP......) perturbation theory for the long range interaction. The lowest-order self-consistency corrections to the wave function and the energy, that enter the perturbation expansions at the second and fourth order, respectively, are both expressed in terms of the one-electron reduced density matrix.

Alcohol consumption contributes significantly to the global burden from disease and injury, and specific patterns of heavy episodic drinking contribute uniquely to this burden. Temporal self-regulation theory and the dual-process model describe similar theoretical constructs that might predict heavy episodic drinking. The aims of this study were to test the utility of temporal self-regulation theory in predicting heavy episodic drinking, and examine whether the theoretical relationships suggested by the dual-process model significantly extend temporal self-regulation theory. This was a predictive study with 149 Australian adults. Measures were questionnaires (self-report habit index, cues to action scale, purpose-made intention questionnaire, timeline follow-back questionnaire) and executive function tasks (Stroop, Tower of London, operation span). Participants completed measures of theoretical constructs at baseline and reported their alcohol consumption two weeks later. Data were analysed using hierarchical multiple linear regression. Temporal self-regulation theory significantly predicted heavy episodic drinking (R 2 =48.0-54.8%, ptheory and the extended temporal self-regulation theory provide good prediction of heavy episodic drinking. Intention, behavioural prepotency, planning ability and inhibitory control may be good targets for interventions designed to decrease heavy episodic drinking. Copyright © 2017 Elsevier Ltd.

In a recent paper by R. Pisarski and S. Rao concerning topologically massive quantum Yang--Mills theory, the expression of the P-even part of the non-Abelian gauge field self-energy at one-loop order is shown to obey a consistency condition, which is not fulfilled by the formula originally presented by S. Deser, R. Jackiw, and S. Templeton. In this comment, I present a recalculation which agress with Pisarski and Rao. copyright 1988 Academic Press, Inc
A Study of Bahramâs Character in Haft Peikar on the Basis of Mazlo Theory

Directory of Open Access Journals (Sweden)

mh Karami

2013-02-01

Full Text Available As a thoughtful poet, Nazami has tried to manifest his main preoccupation, i.e. an ideal man who can be a moral model for the readers, in his works. In Haft Peikar, the basis of Nezamiâs thought is Perfection and self-fulfillment of characters, especially Bahram Goor. For him, such Perfection is not an agonized experience but a happy and hopeful experience which is achieved with regard to both Body and Soul. In this way, Nezamiâs idea is similar to Mazlo theory of personality. Throughout the story, Bahram gradually reaches the level of Knowledge and, as there are dilemmas and denouements in the story, it seems that he gets free from his complexes. In this article, the character of Bahram is compared with the elements of self-fulfillment in Mazlo theory.
Self-Determination Theory With Application to Employee Health Settings.

Occupational health nurses motivate employees to engage in healthy behaviors. Both clinicians and researchers need strong theories on which to base decisions for health programs (e.g., healthy diet) and experimental interventions (e.g., workplace walking). The self-determination theory could be useful as it includes concepts of individual autonomy, competence to perform healthy behaviors, and relationships as predictors of health behaviors and outcomes. In this article, the self-determination theory is described and evaluated using Walker and Avant's criteria. The theory is applied to a population of federal employees who smoke. By increasing employees' ability to autonomously choose smoking cessation programs, support their competence to stop smoking, and improve their relationships with both others who smoke and employee health services, smoking cessation should increase.
Modified free volume theory of self-diffusion and molecular theory of shear viscosity of liquid carbon dioxide.

In previous work on the density fluctuation theory of transport coefficients of liquids, it was necessary to use empirical self-diffusion coefficients to calculate the transport coefficients (e.g., shear viscosity of carbon dioxide). In this work, the necessity of empirical input of the self-diffusion coefficients in the calculation of shear viscosity is removed, and the theory is thus made a self-contained molecular theory of transport coefficients of liquids, albeit it contains an empirical parameter in the subcritical regime. The required self-diffusion coefficients of liquid carbon dioxide are calculated by using the modified free volume theory for which the generic van der Waals equation of state and Monte Carlo simulations are combined to accurately compute the mean free volume by means of statistical mechanics. They have been computed as a function of density along four different isotherms and isobars. A Lennard-Jones site-site interaction potential was used to model the molecular carbon dioxide interaction. The density and temperature dependence of the theoretical self-diffusion coefficients are shown to be in excellent agreement with experimental data when the minimum critical free volume is identified with the molecular volume. The self-diffusion coefficients thus computed are then used to compute the density and temperature dependence of the shear viscosity of liquid carbon dioxide by employing the density fluctuation theory formula for shear viscosity as reported in an earlier paper (J. Chem. Phys. 2000, 112, 7118). The theoretical shear viscosity is shown to be robust and yields excellent density and temperature dependence for carbon dioxide. The pair correlation function appearing in the theory has been computed by Monte Carlo simulations.
Seniors' self-preservation by maintaining established self and defying deterioration - A grounded theory.

The purpose of this classic grounded theory study was to understand how seniors who are living independently resolve issues influenced by visual impairment and high fall risk. We interviewed and observed 13 seniors with visual impairment in their homes. We also interviewed six visual instructors with experience from many hundreds of relevant incidents from the same group of seniors. We found that the seniors are resolving their main concern of "remaining themselves as who they used to be" by self-preservation. Within this category, the strategies maintaining the established self and defying deterioration emerged as the most prominent in our data. The theme maintaining the established self is mostly guided by change inertia and includes living the past (retaining past activities, reminiscing, and keeping the home intact) and facading (hiding impairment, leading to avoidance of becoming a burden and to risk juggling). Defying deterioration is a proactive scheme and involves moving (by exercising, adapting activities, using walking aids, driving), adapting (by finding new ways), and networking by sustaining old support networks or finding new networks. Self-preservation is generic human behavior and modifying this theory to other fields may therefore be worthwhile. In addition, health care providers may have use for the theory in fall preventive planning.
Thought analysis on self-organization theories of MHD plasma

A thought analysis on the self-organization theories of dissipative MHD plasma is presented to lead to three groups of theories that lead to the same relaxed state of ∇ x B = λB, in order to find an essential physical picture embedded in the self-organization phenomena due to nonlinear and dissipative processes. The self-organized relaxed state due to the dissipation by the Ohm loss is shown to be formulated generally as the state such that yields the minimum dissipation rate of global auto-and/or cross-correlations between two quantities in j, B, and A for their own instantaneous values of the global correlations.

1990-01-01

The existence of self-dual or anti-self-dual monopoles of a seven-dimensional generalized Yang-Mills-Higgs theory is proved using the second-order equations of motion. The behavior of solutions can be used to recognize self- or anti-self-duality. Moreover, it is shwon that, in the class of the field configurations under discussion, the solutions are, in fact, unique. (orig.)
Kaehler-Chern-Simons theory and symmetries of anti-self-dual gauge fields

International Nuclear Information System (INIS)

Nair, V.P.; Schiff, J.

1992-01-01

Kaehler-Chern-Simons theory, which was proposed as a generalization of ordinary Chern-Simons theory, is explored in more detail. The theory describes anti-self-dual instantons on a four-dimensional Kaehler manifold. The phase space is the space of gauge potentials, whose symplectic reduction by the constraints of anti-self-duality leads to the moduli space of instantons. We show that infinitesimal Baecklund transformations, previously related to 'hidden symmetries' of instantons, are canonical transformations generated by the anti-self-duality constraints. The quantum wave functions naturally lead to a generalized Wess-Zumino-Witten action, which in turn has associated chiral current algebras. The dimensional reduction of the anti-self-duality equations leading to integrable two-dimensional theories is briefly discussed in this framework. (orig.)

How people develop beliefs about themselves (self-theories) plays an important role on motivation and achievement as shown by Carol Dweck’s life-long research. In this paper, we conduct a field experiment to investigate whether self-theories impact overconfidence and risk taking. Self-theories deal with how an individual perceives some of her attributes such as intelligence, personality or moral character. In this paper, we are interested by how people perceive their mindset (fixed or growth)...
Self-accelerating universe in scalar-tensor theories after GW170817

Crisostomi, Marco; Koyama, Kazuya

2018-04-01

The recent simultaneous detection of gravitational waves and a gamma-ray burst from a neutron star merger significantly shrank the space of viable scalar-tensor theories by demanding that the speed of gravity is equal to that of light. The survived theories belong to the class of degenerate higher order scalar-tensor theories. We study whether these theories are suitable as dark energy candidates. We find scaling solutions in the matter dominated universe that lead to de Sitter solutions at late times without the cosmological constant, realizing self-acceleration. We evaluate quasistatic perturbations around self-accelerating solutions and show that the stringent constraints coming from astrophysical objects and gravitational waves can be satisfied, leaving interesting possibilities to test these theories by cosmological observations.

The Psychology of Conspiracy Theories.

Douglas, Karen M; Sutton, Robbie M; Cichocka, Aleksandra

2017-12-01

What psychological factors drive the popularity of conspiracy theories , which explain important events as secret plots by powerful and malevolent groups? What are the psychological consequences of adopting these theories? We review the current research and find that it answers the first of these questions more thoroughly than the second. Belief in conspiracy theories appears to be driven by motives that can be characterized as epistemic (understanding one's environment), existential (being safe and in control of one's environment), and social (maintaining a positive image of the self and the social group). However, little research has investigated the consequences of conspiracy belief, and to date, this research does not indicate that conspiracy belief fulfills people's motivations. Instead, for many people, conspiracy belief may be more appealing than satisfying. Further research is needed to determine for whom, and under what conditions, conspiracy theories may satisfy key psychological motives.

2017-08-01

Full Text Available The Novgorod archbishop Iona was one of the most important Russian church personalities of the 15th century; he was canonized after his death. Information about his life is contained in different literary monuments of the 15th–16th centuries. One of them was the brief “Tale about the Prophecy of Iona’s Archbishopric.” Researchers believe that this monument became the source of the “Life of Iona.” This article focuses on the history of the text of the “Tale.” First, the article considers the history of research about the “Tale.” Second, the author gives an overview and description of copies of the work, and examines new copies of the “Tale.” Third, the researcher analyzes the editions of the “Tale,” revealing their new features. In conclusion, the investigator considers the question of the influence of the “Tale” on the text of the “Life of Iona.” The author tries to establish the copy of the “Tale” that was used in the “Life.”
Winners, Losers, Insiders, and Outsiders: Comparing Hierometer and Sociometer Theories of Self-Regard

What evolutionary function does self-regard serve? Hierometer theory, introduced here, provides one answer: it helps individuals navigate status hierarchies, which feature zero-sum contests that can be lost as well as won. In particular, self-regard tracks social status to regulate behavioral assertiveness, augmenting or diminishing it to optimize performance in such contests. Hierometer theory also offers a conceptual counterpoint that helps resolve ambiguities in sociometer theory, which offers a complementary account of self-regard’s evolutionary function. In two large-scale cross-sectional studies, we operationalized theoretically relevant variables at three distinct levels of analysis, namely, social (relations: status, inclusion), psychological (self-regard: self-esteem, narcissism), and behavioral (strategy: assertiveness, affiliativeness). Correlational and mediational analyses consistently supported hierometer theory, but offered only mixed support for sociometer theory, including when controlling for confounding constructs (anxiety, depression). We interpret our results in terms of a broader agency-communion framework. PMID:27065896

We generalize and test the recent "ab initio" self-consistent (AISC) time-independent semiclassical laser theory. This self-consistent formalism generates all the stationary lasing properties in the multimode regime (frequencies, thresholds, internal and external fields, output power and emission pattern) from simple inputs: the dielectric function of the passive cavity, the atomic transition frequency, and the transverse relaxation time of the lasing transition.We find that the theory gives excellent quantitative agreement with full time-dependent simulations of the Maxwell-Bloch equations after it has been generalized to drop the slowly-varying envelope approximation. The theory is infinite order in the non-linear hole-burning interaction; the widely used third order approximation is shown to fail badly.

Self-determination theory (SDT) of motivations distinguishes between intrinsic and extrinsic motivations. Intrinsic motivation is observed when one engages in an activity out of genuine interest and is truly self-determined. Intrinsic motivation is the desired type of motivation for study as it is associated with deep learning, better performance and positive well-being in comparison to extrinsic motivation. It is dependent on the fulfilment of three basic psychological needs described by SDT. These are the needs for autonomy, competence and relatedness. According to SDT, autonomy-supportive teaching is important, because it makes students feel autonomous and competent in their learning and also supported (relatedness) by their teachers. The concept of autonomy-supportive teaching is relevant to medical education, but less known. Through this article, we aim to make this concept understood and practically used by medical teachers. We used SDT literature as a basis to formulate these 12 tips. We present 12 practical tips derived from SDT, for teachers in health professions, on how to engage in autonomy-supportive teaching behaviours in order to stimulate intrinsic motivation in their students. These tips demonstrate that it is not difficult to engage in autonomy-supportive teaching behaviour. It can be learned through practice and self-reflection on teaching practices.

We propose a modified scheme for calculating the single-particle excitation spectrum of the impurity Anderson model. It is based on the second order perturbation theory, but modifies the self-energy so as to reproduce the correct atomic limit and to fulfill the Friedel sum rule. Therefore, it offers a simple scheme valid over wide range of excitation energy and parameters, and would be useful also for potential application to the lattice problems. (author)
Self-interaction corrections in density functional theory

International Nuclear Information System (INIS)

Tsuneda, Takao; Hirao, Kimihiko

2014-01-01

Self-interaction corrections for Kohn-Sham density functional theory are reviewed for their physical meanings, formulations, and applications. The self-interaction corrections get rid of the self-interaction error, which is the sum of the Coulomb and exchange self-interactions that remains because of the use of an approximate exchange functional. The most frequently used self-interaction correction is the Perdew-Zunger correction. However, this correction leads to instabilities in the electronic state calculations of molecules. To avoid these instabilities, several self-interaction corrections have been developed on the basis of the characteristic behaviors of self-interacting electrons, which have no two-electron interactions. These include the von Weizsäcker kinetic energy and long-range (far-from-nucleus) asymptotic correction. Applications of self-interaction corrections have shown that the self-interaction error has a serious effect on the states of core electrons, but it has a smaller than expected effect on valence electrons. This finding is supported by the fact that the distribution of self-interacting electrons indicates that they are near atomic nuclei rather than in chemical bonds

To be successful, hospitals must increasingly collaborate with their medical staff. One strategic tool that plays an important role is the mission statement of hospitals. The goal of this research was to study the relationship between the fulfillment of administrative and professional obligations of hospitals on physicians' motivation to contribute to the mission of the hospital. Furthermore the mediating role of the physicians' emotional attachment to the hospital and moderation effect of the exchange with the head physicians were considered. Self-employed physicians of six hospitals participated in a survey. Descriptive analyses and linear regression were used to analyse the data. The results indicate that affective commitment mediated the relationship between psychological contract fulfillment and mission statement motivation. In addition, the quality of exchange with the Chief Medical Officer moderated the relationship between the fulfillment of administrative obligations and affective commitment positively. This study extends our understanding of social exchange processes and mission statement motivation of physicians. We showed that when physicians perceive a high level of fulfillment of their psychological contract they are more committed and more motivated to contribute to the mission statement. A high quality relationship between physician and Chief Medical Officer can enhance this reciprocity dynamic.

Utilizing Rogers' Theory of Self-Concept in mental health nursing.

Science.gov (United States)

Hosking, P

1993-06-01

The work of mental health nurse is interactive in nature, the priority of which is the effective development and maintenance of a therapeutic relationship with clients. This field of nursing bases its practice on theories from many schools of thought in order to provide clients with the highest quality of care. One such theory is that of Carl Rogers whose practice as a psychotherapist was based on his Theory of Self-Concept. This paper examines the development of the Theory of Self-Concept from the works of Cooley, Mead, Allport and Rogers and relates to the therapeutic alliance between a primary nurse and a client who has been medically diagnosed as being 'depressed'. The implications for practice are considered and some of the difficulties of utilizing Rogers' theory on an in-patient unit are explored. The paper emphasizes the need for nurses to be aware of the use of such theories in order to enrich the care that clients receive. It also highlights the need for nurses to be aware of their own 'self' when working with clients, a state that can only be achieved if the nurses themselves have adequate clinical supervision and an environment which is supportive of such work.

Self-handicapping is a maladaptive behavior which undermines students' achievements, but the antecedents of self-handicapping are not well studied in physical education. The aim was to examine the relations of implicit theory of abilities and self-handicapping in physical education. 264 college students, whose mean age was 20.3 yr. (SD = 1.7), completed the Conceptions of the Nature of Athletic Ability Questionnaire-2 and Self-handicapping Scale for Sport. Analysis indicated entity beliefs positively predicted reduced effort and making excuses. Also, incremental beliefs negatively predicted reduced effort. Results are discussed in terms of implicit theory of ability and self-handicapping. Directions for research and implications are stated.

The Sensitiveness and Fulfillment of Psychological Needs: Medical, Health Care and Students.

Rakovec-Felser, Zlatka

2015-09-01

As health was defined as a state of complete physical, mental, and social well-being, and not merely an absence of disease or infirmity, the bio-psychosocial paradigm of health and illness attests that curing occurs when the science of medicine (the biomedical and pathos-physiological aspects of disease) and the art of medicine (the psychological, social, and interpersonal aspects of illness) merge into one unified holistic approach to patient care (Hojat, 2007). In this context the relationship between health care professionals and patients also become an indispensable tool in clinical situations to achieve better patient outcomes (Engel, 1990). In our pilot study in year 2009 we try to verify how are the medical students and students of health care (University of Maribor, Faculty of Medicine and Faculty of Health Care) prepared for their sensitive professional relationship in their future. Testing together 211 students (N=157 women, N=57 men), we compared the level of emotional empathy, altruistic love, values, and behaviorof 40 medical students, 118 students of health care and the group of 53 students of economics. Because of their professional choice, we expected that the medical and health care students would have higher empathy and altruism scores than the students of economics. Following the self-determination behavioral theory and its concept of autonomy support (Deci, Ryan, 2000), we anticipated also that the fulfilment of basic psychological needs could be important factor in everyday health care clinical practice. As the fulfilment of needs of autonomy, competence and relatedness could lead to increased autonomy supportive orientation in interactions with other subjects, and can be useful factor that prepare doctors or nurses for active participation in relationship with patients, we verified and compared the included groups also in this way.

Hemphill, J Claude; White, Douglas B

2009-02-01

Mortality and morbidity remain high from neurologic emergencies, such as acute stroke, traumatic brain injury, and hypoxic-ischemic encephalopathy after cardiac arrest. Decisions regarding initial aggressiveness of care must be made at the time of presentation, and perceived prognosis is often used as part of this decision-making process. These decisions are predicated on the accuracy of early outcome prediction, however. Decisions to limit treatment early after neuroemergencies must be balanced with avoidance of self-fulfilling prophecies of poor outcome attributable to clinical nihilism. This article examines the role of prognostication early after neuroemergencies, the potential impact of early treatment limitations, and how these may relate to communication with patients and surrogate decision makers in the context of these acute neurologic events.

This review builds on self-control theory (Carver & Scheier, 1998) to develop a theoretical framework for investigating associations of implicit theories with self-regulation. This framework conceptualizes self-regulation in terms of 3 crucial processes: goal setting, goal operating, and goal monitoring. In this meta-analysis, we included…

Physical or psychological well-being is an essential component of quality care assessment in palliative unit. This assessment is mainly based on self-assessment (questionnaires or interviews). The aim of this study is to compare the clinical characteristics of patients able to fulfill a questionnaire and those not able to do that. The clinical characteristics of 166 cancer patients admitted in palliative care unit from December 2006 to February 2008 have been collected. Characteristics of patients able to fulfill a questionnaire (80, 48.2%) have been compared to other patients (86, 51.8%). Moreover, functional independence measure (FIM) had been evaluated by nurses. Median age (60 versus 62) and sex ratio (40/40 versus 42/44) are similar in both groups. Lung primaries are significantly less frequent in patients able to fulfill the questionnaire (4% versus 17%, P=0.005). Patients able to fulfill the questionnaire had had better performance status (Karnofsky Index≤30%: 54% versus 21%, Ppatients non able to fulfill the questionnaire. Patients able to fulfill a questionnaire represent only 48.2% of all consecutive admitted patients. These patients are not representative of all patients since they had better performance status, they are less dependent and they display significant better survival. We have to think about new methods to avoid the biases generated by the use of patient-reported outcomes. Copyright © 2015 Société Française du Cancer. Published by Elsevier Masson SAS.

What is life? According to Erwin Schrödinger [13], the living cell departs from other physical systems in that it - apparently - resists the second law of thermodynamics by restricting the dynamical repertoire (minimizing the entropy) of its physiological states. This is a physical rephrasing of Claude Bernard's biological notion of homeostasis, namely: the capacity of living systems to self-organize in order to maintain the stability of their internal milieu despite uninterrupted exchanges with an ever-altering external environment [2]. The important point here is that physical systems can neither identify nor prevent a state of high entropy. The Free Energy Principle or FEP was originally proposed as a mathematical description of how the brain actually solves this issue [4]. In line with the Bayesian brain hypothesis, the FEP views the brain as a hierarchical statistical learning machine, endowed with the imperative of minimizing Free Energy, i.e. prediction error. Action prescription under the FEP, however, does not follow standard Bayesian decision theory. Rather, action is assumed to further minimize Free Energy, which makes the active brain a self-fulfilling prophecy machine [6]. This is adaptive, under the assumption that evolution has equipped the brain with innate priors centered on homeostatic set points. In turn, avoiding (surprising) violations of such prior predictions implements homeostatic regulation [10], which becomes increasingly anticipatory as learning unfolds over the course of ontological development [5].

Approximate self-consistent potentials for density-functional-theory exchange-correlation functionals

International Nuclear Information System (INIS)

Cafiero, Mauricio; Gonzalez, Carlos

2005-01-01

We show that potentials for exchange-correlation functionals within the Kohn-Sham density-functional-theory framework may be written as potentials for simpler functionals multiplied by a factor close to unity, and in a self-consistent field calculation, these effective potentials find the correct self-consistent solutions. This simple theory is demonstrated with self-consistent exchange-only calculations of the atomization energies of some small molecules using the Perdew-Kurth-Zupan-Blaha (PKZB) meta-generalized-gradient-approximation (meta-GGA) exchange functional. The atomization energies obtained with our method agree with or surpass previous meta-GGA calculations performed in a non-self-consistent manner. The results of this work suggest the utility of this simple theory to approximate exchange-correlation potentials corresponding to energy functionals too complicated to generate closed forms for their potentials. We hope that this method will encourage the development of complex functionals which have correct boundary conditions and are free of self-interaction errors without the worry that the functionals are too complex to differentiate to obtain potentials

MOTIVATING ENGLISH TEACHERS BASED ON THE BASIC NEEDS THEORY AND AN EXPECTANCY THEORY

Directory of Open Access Journals (Sweden)

Hidayatus Sholihah

2017-08-01

Full Text Available There are two main motivation theories. a hierarchy of basic needs theory, and an expectancy theory. In a Hyrarchy of basic needs theory, Maslow has stated that the basic needs as a main behaviour direction are structured into a hierarchy. There are five basic human needs. The first: Physiological needs such as: salary, bonus or working condition. The second: the safety needs, such as: safe job environment, job security or health cover. The third, social needs, such as union and team work. The next is self esteem, such as getting an award, medal, certificate or any other recognisition. Then the last is self actualization, for example is by providing an opportunity to share knowledge, skills and eprerience. The evaluation of this theory are: there is no spiritual needs as human basic needs is a main weakness of this theory. Then it is possible that different level of needs have to be satisfied in the same time, or not in hierarchy level or, not always have to be fulfilled in order. The next motivation theory is an Expectancy Theory. This theory is based on three main factors. The first factor is: English teachers will be motivated to work harder if they have a good perception to their own competences in accordance with their job. The second, individual motivation depends on the rewards given when they finish a particular job. Finally, it also depends on their regards to the rewards given from the job that they do. Expectancy theory is a good theory, however, it is not easy to be implemented because the principals should provide various types of reward to satisfy the expectation of their English teachers. Considering the strengths and weaknesses of these two theories, it is better to combine both of them in the practice to get more effective results.
Mean fields and self consistent normal ordering of lattice spin and gauge field theories

International Nuclear Information System (INIS)

Ruehl, W.

1986-01-01

Classical Heisenberg spin models on lattices possess mean field theories that are well defined real field theories on finite lattices. These mean field theories can be self consistently normal ordered. This leads to a considerable improvement over standard mean field theory. This concept is carried over to lattice gauge theories. We construct first an appropriate real mean field theory. The equations determining the Gaussian kernel necessary for self-consistent normal ordering of this mean field theory are derived. (orig.)
Workplace Bullying and Work Engagement: A Self-Determination Model.

Goodboy, Alan K; Martin, Matthew M; Bolkan, San

2017-06-01

This study modeled motivational mechanisms that explain the negative effects of workplace bullying on work engagement. Guided by self-determination theory, workplace bullying was predicted to decrease worker engagement indirectly, due to the denial of employees' basic psychological needs and their intrinsic motivation to work. From a sample of 243 full-time employees, serial multiple mediation models revealed that the indirect relationships between workplace bullying and work engagement (i.e., vigor, dedication, absorption) were serially mediated by basic psychological needs and intrinsic motivation to work. In support of self-determination theory, this study revealed that workplace bullying indirectly disengages employees from their work by denying them of their autonomy and relatedness needs and thwarting their motivation to perform work in a fulfilling way.

Facilitating internalization: the self-determination theory perspective.

Science.gov (United States)

Deci, E L; Eghrari, H; Patrick, B C; Leone, D R

1994-03-01

Self-determination theory (Deci & Ryan, 1985) posits that (a) people are inherently motivated to internalize the regulation of uninteresting though important activities; (b) there are two different processes through which such internalization can occur, resulting in qualitatively different styles of self-regulation; and (c) the social context influences which internalization process and regulatory style occur. The two types of internalization are introjection, which entails taking in a value or regulatory process but not accepting it as one's own, and integration, through which the regulation is assimilated with one's core sense of self. Introjection results in internally controlling regulation, whereas integration results in self-determination. An experiment supported our hypothesis that three facilitating contextual factors--namely, providing a meaningful rationale, acknowledging the behaver's feelings, and conveying choice--promote internalization, as evidenced by the subsequent self-regulation of behavior. This experiment also supported our expectation that when the social context supports self-determination, integration tends to occur, whereas when the context does not support self-determination, introjection tends to occur.
Self-determination theory and understanding of student motivation in physical education instruction

Directory of Open Access Journals (Sweden)

Đorđić Višnja

2010-01-01

Full Text Available Physical education is considered to be a favorable context for accomplishment of important educational outcomes and promotion of physical activity in children and youth. The real scope of physical education instruction largely depends on student motivation. Self-determination theory, as a specific macrotheory of motivation, offers a rewarding framework for understanding student motivation in physical education instruction. The paper presents the basic tenets of self-determination theory, the most important studies in the domain of physical education and didactic and methodical implications. Two mini-theories within the self-determination theory are analyzed in more detail, the cognitive evaluation theory and the organismic integration theory. Empirical verification of the theoretical tenets indicates the existence of typical motivational profiles of students in physical education instruction, the basic psychological needs as mediators of influence of social and interpersonal factors on student motivation, followed by the importance of motivational climate, students' goal orientations and teaching style for self-determination of students' behavior in physical education instruction. Didactic and methodical implications refer to the need for developing a more flexible curriculum of physical education, encouraging a motivational climate, task-focused goal orientations, and, especially, encouraging the perceived moving competence of the student.

The individual-oriented and social-oriented Chinese bicultural self: testing the theory.

Science.gov (United States)

Lu, Luo

2008-06-01

The author proposes a bicultural self theory for contemporary Chinese individuals, encompassing 2 main components: the individual-oriented self and the social-oriented self. The social orientation is rooted in traditional Chinese conceptualization of the self, whereas the individual orientation has evolved and developed under Western influences along with recent societal modernization. The author conducted a series of 5 studies to test the theory and relate the model to important issues in current personality and social psychological research, such as cultural individualism-collectivism, self-construals, motivation, cognition, emotion, and well-being. A total of 977 university students in Taiwan participated. The author found that contrasting self-aspects were differentially associated with the aforementioned constructs, as theoretically predicted. This evidence thus generally supported the bicultural self model.
A Middle-Range Theory for Diabetes Self-management Mastery.

Science.gov (United States)

Fearon-Lynch, Jennifer A; Stover, Caitlin M

2015-01-01

Diabetes mellitus is the seventh leading cause of death in America and affects 382 million people worldwide. Individuals with diabetes must manage the complexity of the disease, its treatment, and complications to avert deleterious consequences associated with the illness. However, not all patients with diabetes successfully gain mastery to positively impact self-management. A new middle-range theory is proposed that merges 2 extant theories, theory of mastery and organismic integration theory, to better understand this human response. The theories' philosophical, theoretical, and conceptual perspectives were examined and relational properties synthesized to provide a conceptual representation of the phenomenon of interest.

Several theories propose that self-esteem, or positive self-regard, results from fulfilling the value priorities of one's surrounding culture. Yet, surprisingly little evidence exists for this assertion, and theories differ about whether individuals must personally endorse the value priorities involved. We compared the influence of four bases for self-evaluation (controlling one's life, doing one's duty, benefitting others, achieving social status) among 4,852 adolescents across 20 cultural samples, using an implicit, within-person measurement technique to avoid cultural response biases. Cross-sectional and longitudinal analyses showed that participants generally derived feelings of self-esteem from all four bases, but especially from those that were most consistent with the value priorities of others in their cultural context. Multilevel analyses confirmed that the bases of positive self-regard are sustained collectively: They are predictably moderated by culturally normative values but show little systematic variation with personally endorsed values.
Self-complementary circular codes in coding theory.

Fimmel, Elena; Michel, Christian J; Starman, Martin; Strüngmann, Lutz

2018-04-01

Self-complementary circular codes are involved in pairing genetic processes. A maximal [Formula: see text] self-complementary circular code X of trinucleotides was identified in genes of bacteria, archaea, eukaryotes, plasmids and viruses (Michel in Life 7(20):1-16 2017, J Theor Biol 380:156-177, 2015; Arquès and Michel in J Theor Biol 182:45-58 1996). In this paper, self-complementary circular codes are investigated using the graph theory approach recently formulated in Fimmel et al. (Philos Trans R Soc A 374:20150058, 2016). A directed graph [Formula: see text] associated with any code X mirrors the properties of the code. In the present paper, we demonstrate a necessary condition for the self-complementarity of an arbitrary code X in terms of the graph theory. The same condition has been proven to be sufficient for codes which are circular and of large size [Formula: see text] trinucleotides, in particular for maximal circular codes ([Formula: see text] trinucleotides). For codes of small-size [Formula: see text] trinucleotides, some very rare counterexamples have been constructed. Furthermore, the length and the structure of the longest paths in the graphs associated with the self-complementary circular codes are investigated. It has been proven that the longest paths in such graphs determine the reading frame for the self-complementary circular codes. By applying this result, the reading frame in any arbitrary sequence of trinucleotides is retrieved after at most 15 nucleotides, i.e., 5 consecutive trinucleotides, from the circular code X identified in genes. Thus, an X motif of a length of at least 15 nucleotides in an arbitrary sequence of trinucleotides (not necessarily all of them belonging to X) uniquely defines the reading (correct) frame, an important criterion for analyzing the X motifs in genes in the future.
Implicit theories about willpower predict the activation of a rest goal following self-control exertion.

Science.gov (United States)

Job, Veronika; Bernecker, Katharina; Miketta, Stefanie; Friese, Malte

2015-10-01

Past research indicates that peoples' implicit theories about the nature of willpower moderate the ego-depletion effect. Only people who believe or were led to believe that willpower is a limited resource (limited-resource theory) showed lower self-control performance after an initial demanding task. As of yet, the underlying processes explaining this moderating effect by theories about willpower remain unknown. Here, we propose that the exertion of self-control activates the goal to preserve and replenish mental resources (rest goal) in people with a limited-resource theory. Five studies tested this hypothesis. In Study 1, individual differences in implicit theories about willpower predicted increased accessibility of a rest goal after self-control exertion. Furthermore, measured (Study 2) and manipulated (Study 3) willpower theories predicted an increased preference for rest-conducive objects. Finally, Studies 4 and 5 provide evidence that theories about willpower predict actual resting behavior: In Study 4, participants who held a limited-resource theory took a longer break following self-control exertion than participants with a nonlimited-resource theory. Longer resting time predicted decreased rest goal accessibility afterward. In Study 5, participants with an induced limited-resource theory sat longer on chairs in an ostensible product-testing task when they had engaged in a task requiring self-control beforehand. This research provides consistent support for a motivational shift toward rest after self-control exertion in people holding a limited-resource theory about willpower.

Three remarks on Powers' theorem about irreducible fields fulfilling CAR

International Nuclear Information System (INIS)

Baumann, K.

1986-01-01

First it is shown that within a relativistic Fermi field theory, a bound parallelPsi/sub k/( f,t)parallel 2 already implies canonical anticommutation relations (CAR). Then under Powers' assumptions a linear, first-order differential equation for the fields psi/sub k/(x,t) is derived. This shows that in the set of generalized free fields fulfilling CAR only the free fields are irreducible at time zero. Finally Fermi fields in two space-time dimensions are considered. It is shown that only four-fermion interaction might be compatible with CAR and a bound on the coupling strength is derived
Self-regulation theory: applications to medical education: AMEE Guide No. 58.

Science.gov (United States)

Sandars, John; Cleary, Timothy J

2011-01-01

Self-regulation theory, as applied to medical education, describes the cyclical control of academic and clinical performance through several key processes that include goal-directed behaviour, use of specific strategies to attain goals, and the adaptation and modification to behaviours or strategies to optimise learning and performance. Extensive research across a variety of non-medical disciplines has highlighted differences in key self-regulation processes between high- and low-achieving learners and performers. Structured identification of key self-regulation processes can be used to develop specific remediation approaches that can improve performance in academic and complex psycho-motor skills. General teaching approaches that are guided by a self-regulation perspective can also enhance academic performance. Self-regulation theory offers an exciting potential for improving academic and clinical performance in medical education.
The quantal theory of how the immune system discriminates between "self and non-self"

Science.gov (United States)

Smith, Kendall A

2004-12-17

In the past 50 years, immunologists have accumulated an amazing amount of information as to how the immune system functions. However, one of the most fundamental aspects of immunity, how the immune system discriminates between self vs. non-self, still remains an enigma. Any attempt to explain this most intriguing and fundamental characteristic must account for this decision at the level of the whole immune system, but as well, at the level of the individual cells making up the immune system. Moreover, it must provide for a molecular explanation as to how and why the cells behave as they do. The "Quantal Theory", proposed herein, is based upon the "Clonal Selection Theory", first proposed by Sir McFarland Burnet in 1955, in which he explained the remarkable specificity as well as diversity of recognition of everything foreign in the environment. The "Quantal Theory" is built upon Burnet's premise that after antigen selection of cell clones, a proliferative expansion of the selected cells ensues. Furthermore, it is derived from experiments which indicate that the proliferation of antigen-selected cell clones is determined by a quantal, "all-or-none", decision promulgated by a critical number of cellular receptors triggered by the T Cell Growth Factor (TCGF), interleukin 2 (IL2). An extraordinary number of experiments reported especially in the past 20 years, and detailed herein, indicate that the T cell Antigen Receptor (TCR) behaves similarly, and also that there are several critical numbers of triggered TCRs that determine different fates of the T cells. Moreover, the fates of the cells appear ultimately to be determined by the TCR triggering of the IL2 and IL2 receptor (IL2R) genes, which are also expressed in a very quantal fashion. The "Quantal Theory" states that the fundamental decisions of the T cell immune system are dependent upon the cells receiving a critical number of triggered TCRs and IL2Rs and that the cells respond in an all-or-none fashion.

Relational-interdependent self-construal as a predictor of relationship quality: the mediating roles of one's own behaviors and perceptions of the fulfillment of friendship functions.

Science.gov (United States)

Morry, Marian M; Kito, Mie

2009-06-01

Relational-interdependent self-construal (RISC) is the tendency to think of oneself in terms of relationships with close others, and it influences relationship cognitions (e.g., closeness, commitment, perceived similarity). The authors expected individuals high in RISC to report more relationship supportive behaviors (RSB; e.g., higher levels of trust, more intimate disclosures), experience greater fulfillment of friendship functions (FrFu; e.g., help, emotional security, stimulating companionship), and report higher relationship quality than individuals low in RISC. The authors also hypothesized that RSB would mediate the RISC-friendship function and the RISC-relationship quality relations and that FrFu would mediate the relation between RSB and relationship quality. Structural equation modeling supported the authors' hypotheses. These effects did not differ across friendship type (same or cross sex). The authors discuss the importance of self-construal for relationship research.

The function of self-esteem in terror management theory and sociometer theory: comment on Pyszczynski et al. (2004).

Science.gov (United States)

Leary, Mark R

2004-05-01

By applying different standards of evidence to sociometer theory than to terror management theory (TMT), T. Pyszczynski, J. Greenberg, S. Solomon, J. Arndt, and J. Schimel's (2004) review offers an imbalanced appraisal of the theories' merits. Many of Pyszczynski et al.'s (2004) criticisms of sociometer theory apply equally to TMT. and others are based on misconstruals of the theory or misunderstandings regarding how people respond when rejected. Furthermore, much of their review is only indirectly relevant to TMT's position on the function of self-esteem, and the review fails to acknowledge logical and empirical challenges to TMT. A more balanced review suggests that each theory trumps the other in certain respects, both have difficulty explaining all of the evidence regarding self-esteem, and the propositions of each theory can be roughly translated into the concepts of the other. For these reasons, declaring a theoretical winner at this time is premature. ((c) 2004 APA, all rights reserved)

1980-01-01

A self-consistent cluster theory for elementary excitations in systems with diagonal, off-diagonal, and environmental disorder is presented. The theory is developed in augmented space where the configurational average over the disorder is replaced by a ground-state matrix element in a translationally invariant system. The analyticity of the resulting approximate Green's function is proved. Numerical results for the self-consistent single-site and pair approximations are presented for the vibrational and electronic properties of disordered linear chains with diagonal, off-diagonal, and environmental disorder

Wanting, having, and needing: integrating motive disposition theory and self-determination theory.

Science.gov (United States)

Sheldon, Kennon M; Schüler, Julia

2011-11-01

Four studies explored the motivational and experiential dynamics of psychological needs, applying both self-determination theory and motive disposition theory. In all 4 studies, motive dispositions toward achievement and affiliation ("wanting" particular experiences) predicted corresponding feelings of competence and relatedness ("having" those experiences). Competence and relatedness in turn predicted well-being, again indicating that these 2 experiences may really be "needed." Illuminating how wanting gets to having, in Studies 2 and 3, participants reported greater self-concordance for motive-congruent goals, which, in longitudinal Study 3, predicted greater attainment of those goals and thus enhanced well-being. Study 4 replicated selected earlier results using an implicit as well as an explicit motive disposition measure. Supporting the presumed universality of competence and relatedness needs, in no studies did motive dispositions moderate the effects of corresponding need-satisfaction on well-being. Discussion focuses on a "sequential process" model of psychological needs that views needs as both motives that instigate and outcomes that reward behavior.

Disinhibition of negative true self for identity reconstructions in cyberspace: Advancing self-discrepancy theory for virtual setting.

Directory of Open Access Journals (Sweden)

Chuan Hu

Full Text Available In face-to-face communications, to avoid sanctions and disapproval from others, people are more likely to hide negative aspects of their true self (such as socially undesirable personalities, minds, beliefs and consciousness to avoid conflict with social norms and laws. The anonymity of cyberspace provides people a unique environment to behave more freely and openly with less restraint from the real word. Existing research related to online true self expression has mainly explored true self as an independent aspect of self. Regarding true self as a two-dimensional concept, this study investigates true self from the perspective of individuals' self-guide and identity reconstruction in both online and offline world. Using qualitative research methods, the current study investigates 57 participants through interviews and questionnaires. Content analysis reveals four factors that motivate people to express more true self (especially negative true self when reconstructing their online identity and involve true self as a part of their self-guide in anonymous environment. By incorporating true self as an important part of individuals' self-guide and identity online, the current study advances self-discrepancy theory, making it more comprehensive for cyberspace. The results are also interpreted based on self-determination theory. The theoretical contributions of this study are discussed and practical implications are also presented.
The Self-Perception Theory vs. a Dynamic Learning Model

OpenAIRE

Swank, Otto H.

2006-01-01

Several economists have directed our attention to a finding in the social psychological literature that extrinsic motivation may undermine intrinsic motivation. The self-perception (SP) theory developed by Bem (1972) explains this finding. The crux of this theory is that people remember their past decisions and the extrinsic rewards they received, but they do not recall their intrinsic motives. In this paper I show that the SP theory can be modeled as a variant of a conventional dynamic learn...

We have also performed canonical ensemble molecular dynamics simulations by using the Hoover-Nosé thermostat and the mean-square displacement formula to compute self-diffusion coefficients for the reference WCA intermolecular potential. The good agreement obtained from both methods, when compared with experimental data, suggests that the smooth-effective-sphere theory is a useful procedure to correlate diffusivity of pure substances.

Full Text Available Interactions with parents are known to have a significant impact on children's self-esteem. In this study, designed to test propositions derived from Achievement Goal Theory and Self-Determination Theory, we assessed the influence of perceived parent-initiated mastery and ego motivational climates on self-esteem and self-esteem change in competitive youth swimmers over the course of a 32-week sport season. At each of three measurement points (early, mid, and late season, mastery climate scores on the Parent-Initiated Motivational Climate Questionnaire-2 scale were positively related to global self-esteem scores and to a measure of relative motivational autonomy that reflects the intrinsic-extrinsic motivation continuum, whereas ego climate scores were negatively related to self-esteem and autonomy. Longitudinal analyses revealed that early-season mastery climate predicted positive changes in self-esteem over the course of the season, whereas ego climate predicted decreased self-esteem. Consistent with predictions derived from Self-Determination Theory, a meditational analysis revealed that these self-esteem changes were mediated by changes in autonomous motivation.
The life mission theory V. Theory of the anti-self (the shadow) or the evil side of man.

According to the life mission theory, the essence of man is his purpose of life, which comes into existence at conception. This first purpose is always positive and in support of life. This is not in accordance with the everyday experience that man also engages in evil enterprises born out of destructive intentions. This paper presents a theory about the evil side of man, called the "anti-self" (the shadow), because it mirrors the self and its purpose of life. The core of the anti-self is an evil and destructive intention opposite to the intention behind the life mission. The evil side of man arises when, as the life mission theory proclaims, man is denying his good, basic intention to avoid existential pain. The present theory of the anti-self claims that all the negative decisions accumulated throughout the personal history, sum up to a negative or dark anti-self, as complex, multifaceted, and complete as the self. All the negative decisions taken through personal history build this solid, negative, existential structure. The anti-self, or shadow as Carl Gustav Jung used to call it, is a precise reflection of man's basically good and constructive nature. When mapped, it seems that for most or even for all the many fine talents of man, there is a corresponding evil intention and talent in the person's anti-self. As man is as evil as he is good, he can only realize his good nature and constructive talents by making ethical choices. Ethics therefore seem to be of major importance to every patient or person engaged in the noble project of personal growth. Understanding the nature and structure of the evil side of man seems mandatory to every physician or therapist offering existential therapy to his patient. The theory of anti-self makes it possible to treat patients with destructive behavioral patterns, who want to be good deep in their heart, by helping them let go of their evil intentions. The anti-self also seems to explain the enigma of why human beings often
A Preliminary Application of Social Cognitive Theory to Nonsuicidal Self-Injury.

Researchers have established a relationship between exposure to nonsuicidal self-injury (NSSI), and increased probability of engaging in the behavior, but few have endeavored to explain the mechanisms underlying the relationship. We drew on Social Cognitive Theory to argue that core cognitions, including NSSI outcome expectancies and self-efficacy expectancies, moderate this relationship. We also explored whether knowledge about NSSI and attitudes toward the behavior played a role in this relationship. A sample of 389 university students (73.1 % female, M age = 20.90, SD = 2.36), completed online questionnaires assessing the constructs of interest. Our findings support the application of Social Cognitive Theory to better understanding NSSI, with clear links between expectancies, self-efficacy and NSSI. Further, these cognitions moderated a number of exposure-NSSI relationships. Implications of these findings for theory, research and intervention are discussed.

Full Text Available This article aims at understanding the role played by the discussions about slavery and slave trafficking in the literate culture of Brazil in the 19th century, especially regarding the forms of figuring out the future of the nation. The way Canon Januário da Cunha Barbosa, an important politician and an illustrated intellectual, related projections of the future of the nation and treated the slavery issue (from 1830 to 1836 is analyzed. We discuss the use of projection modalities: prophecy and prognosis. Through them, Januário was involved in political discussions regarding the end of slave trafficking, and made political use of the Malê Revolt and Haitianism. The constitution of a horizon of antislavery expectation is indicated by the Canon, which is seen as one of the reasons to create the Brazilian Historic and Geographic Institute (1838.
Derivations and comparisons of three groups of self-organization theories for magnetohydrodynamic plasmas

A theoretical investigation on self-organization theories of dissipative MHD plasmas is presented to derive three groups of theories that lead to the same relaxed state of ∇xB=λB, in order to find more essential physical picture embedded in self-organization phenomena due to nonlinear and dissipative processes. Comparisons among all of the theories treated and derived here suggest that a theory standing upon spectrum spreadings and selective dissipations of eigenmodes for the dissipative operator-∇xηj and leading to self-organized relaxed states of ∇xηj=αB/2 with the minimum dissipation rate is the most agreeable to various results obtained by experiments and by 3-D MHD simulations reported so far.

A proof of fulfillment of the strong bootstrap condition

Fadin, V.S.; Papa, A.

2002-01-01

It is shown that the kernel of the BFKL equation for the octet color state of two Reggeized gluons satisfies the strong bootstrap condition in the next-to-leading order. This condition is much more restrictive than the one obtained from the requirement of the Reggeized form for the elastic scattering amplitudes in the next-to-leading approximation. It is necessary, however, for self-consistency of the assumption of the Reggeized form of the production amplitudes in multi-Regge kinematics, which are used in the derivation of the BFKL equation. The fulfillment of the strong bootstrap condition for the kernel opens the way to a rigorous proof of the BFKL equation in the next-to-leading approximation. (author)
The self-mass of vector bosons in gravity-modified quantum field theories

International Nuclear Information System (INIS)

Poelt, P.

1985-01-01

The self-mass of the W-boson is calculated using a gravitational modified Weinberg-Salam theory with an anomalous magnetic moment assumed to be variable. The self-mass is shown to be finite with Gsub(N)sup(-1/2) (Gsub(N) Newton's gravitational constant) as the cutoff parameter. But only certain values of the anomalous magnetic moment yield a correct order of magnitude. Lowest order of perturbation theory gives complex solutions for these magnetic moments. Nevertheless, additional terms of higher perturbation theory will modify the equation for the magnetic moment and possibly lead to the definite magnetic moment of the W-boson of the non-modified Weinberg-Salam theory.

Addiction as an attempt at self-regulation (contemporary psychoanalytic theories of addiction

Directory of Open Access Journals (Sweden)

Gregor Žvelc

2001-09-01

Full Text Available In the article author presents the development of psychoanalytic theory of addiction from early writings to contemporary ego, self psychological and theories of object relations. Classical psychoanalysis understood addiction as a regressive gratification of libidinal drives, whereas contemporary authors understand it as an attempt of adaptation to certain problems and worries. The neurotic conflict is not anymore in the foreground, but disturbances in ego, self and object relations. On the basis of a review of contemporary psychoanalytical theories, the author concludes that individuals prone to addiction have a disturbance in self-regulation. Because of that, they have problems in tolerating and coping with certain emotions. With the help of outer means they tend to re-establish internal balance, which they can't manage alone. This outer 'help' can be seen in various forms of addiction (drugs, food, relationships, sex .... So, the core problem of addicted people is a deficit of self-regulation, which is a consequence of a lack of internalisaton of regulatory functions of primary object. Contemporary psychoanalytical theories of addiction bring us greater insight in personality factors which influence the formation of addiction, thus giving us guidelines for adequate psychotherapy of addiction.
Elements of automata theory and the theory of Markov chains. [Self-organizing control systems

Energy Technology Data Exchange (ETDEWEB)

Lind, M

1975-03-01

Selected topics from automata theory and the theory of Markov chains are treated. In particular, finite-memory automata are discussed in detail, and the results are used to formulate an automation model of a class of continuous systems. Stochastic automata are introduced as a natural generalization of the deterministic automaton. Markov chains are shown to be closely related to stochastic automata. Results from Markov chain theory are thereby directly applicable to analysis of stochastic automata. This report provides the theoretical foundation for the investigation in Riso Report No. 315 of a class of self-organizing control systems. (25 figures) (auth)
First-person perspective effects on theory of mind without self-reference.

Yuki Otsuka

Full Text Available This study examined dissociations between brain networks involved in theory of mind, which is needed for guessing others' mental states, and the self, which might constitute the basis for theory of mind's development. We used event-related fMRI to compare a condition that required participants to guess the mental state of a subject featured in first-person perspective sentences (1stPP condition with a third-person perspective sentence condition (3rdPP condition. The caudate nucleus was marginally more activated in the 1stPP than in the 3rdPP condition, while the left dorsolateral prefrontal cortex (DLPFC was significantly more activated in the 3rdPP condition as compared to the 1stPP condition. Furthermore, we examined the correlation between activation (signal intensity of the caudate nucleus and left DLPFC with that of the right DLPFC, which is thought to be closely connected with sense of self. We found a significant correlation between caudate nucleus and right DLPFC activation in the 1stPP condition, and between left and right DLPFC activation in the 3rdPP condition. Although theory of mind and the self both appear to recruit the right DLPFC, this region seems to be accessed through the left DLPFC during theory of mind tasks, but through the caudate nucleus when tasks require self reference.

Integrating Implicit Leadership Theories, Leader-Member Exchange, Self-Efficacy, and Attachment Theory to Predict Job Performance.

Science.gov (United States)

Khorakian, Alireza; Sharifirad, Mohammad Sadegh

2018-01-01

The impact of implicit leadership theories on performance and the mechanism linking them have received insufficient theoretical and research attention. Drawing on Bandura's social cognitive theory, the present study contributes theory through examining the assertion that higher congruence between followers' implicit leadership theory and the characteristics of supervisors enhance job performance through higher quality of leader-member exchange and self-efficacy. Moreover, in the proposed model, attachment insecurity was considered as the antecedent of the congruence and leader-member exchange in addition to the moderator of the relationship between them. Capitalizing upon Structural Equation Modeling (SEM), this study tested the model in a field study using a sample of employees in knowledge-oriented firms in Iran. The results suggest that the congruence between followers' implicit leadership theory and the characteristics of supervisors does not directly impact performance and leader-member exchange and self-efficacy are the full mediators. The results also showed that attachment insecurity is the predictor of neither the congruence nor the leader-member exchange. Additionally, attachment insecurity moderates the relationship between these two variables in a way that when attachment insecurity is high, the congruence has more positive impact on leader-member exchange.

Whilst the original hypothesis posited that it is individuals low in self-esteem that are motivated to show intergroup discrimination, subsequent research has found evidence to suggest a pattern of individuals high in self esteem showing greater amounts of intergroup discrimination. Furthermore, the Social Identity Theory suggests that this intergroup discrimination will occur between membe...

Borhaninejad, Vahidreza; Iranpour, Abedin; Shati, Mohsen; Tahami, Ahmad Naghibzadeh; Yousefzadeh, Gholamrezan; Fadayevatan, Reza

Diabetes is one of the most common chronic diseases among the elderly and is also a very serious health problem. Adopting theory-based self-care behaviors is an effective means in managing such diseases. This study aimed to determine the predictors of diabetes self-care in the elderly in Kerman based on a social cognitive theory. In this cross-sectional study, 384 elderly diabetic patients who had referred to health screening centers in Kerman were chosen via cluster sampling. To collect information about self-care and its predictors, Toobert Glasgow's diabetes self-efficacy scale as well as a questionnaire was used which was based on social cognitive theory constructs. The validity and reliability of the questionnaire was confirmed. The data were analyzed using Pearson correlation and linear regression analysis in SPSS software 17. Among the subjects, 67.37% (252) had poor self-care ability; 29.14% (109) had average ability, and 3.40% (13) enjoyed a proper level of self- care ability. There was a significant relationship between the constructs of the social cognitive theory (knowledge, self- efficacy, social support, outcome expectations, outcome expectancy and self-regulation) and the self-care score. Furthermore, the mentioned constructs could predict 0.47% of the variance of the self-care behaviors. self-care behaviors in this study were poor. Therefore, it is necessary to develop an educational intervention based on cognitive theory constructs with the goal of properly managing diabetes in the elderly patients.

Particle linear theory on a self-gravitating perturbed cubic Bravais lattice

International Nuclear Information System (INIS)

Marcos, B.

2008-01-01

Discreteness effects are a source of uncontrolled systematic errors of N-body simulations, which are used to compute the evolution of a self-gravitating fluid. We have already developed the so-called ''particle linear theory''(PLT), which describes the evolution of the position of self-gravitating particles located on a perturbed simple cubic lattice. It is the discrete analogue of the well-known (Lagrangian) linear theory of a self-gravitating fluid. Comparing both theories permits us to quantify precisely discreteness effects in the linear regime. It is useful to develop the PLT also for other perturbed lattices because they represent different discretizations of the same continuous system. In this paper we detail how to implement the PLT for perturbed cubic Bravais lattices (simple, body, and face-centered) in a cubic simulation box. As an application, we will study the discreteness effects--in the linear regime--of N-body simulations for which initial conditions have been set up using these different lattices.

2011-04-07

The provision of information appears to be an important property of self-esteem as evidenced by previous research concerning the status-tracking and status-signaling models of self-esteem. The present studies examine whether there is an implicit theory of self-esteem that leads individuals to assume targets with higher levels of self-esteem possess more desirable characteristics than those with lower levels of self-esteem. Across 6 studies, targets with ostensibly higher levels of self-esteem were generally rated as more attractive and as more desirable relationship partners than those with lower levels of self- esteem. It is important to note, however, that this general trend did not consistently emerge for female targets. Rather, female targets with high self-esteem were often evaluated less positively than those with more moderate levels of self-esteem. The present findings are discussed in the context of an extended informational model of self-esteem consisting of both the status-tracking and status-signaling properties of self-esteem.

In this introductory article we first describe the impetus for this special issue. What made us think that Self-Determination Theory (SDT) might provide a sort of foundation for the rest of personality psychology? For readers unfamiliar with SDT, we then provide a historical overview which covers the evolution of the six "mini-theories" that currently comprise SDT: cognitive evaluation theory, causality orientations theory, organismic integration theory, basic psychological needs theory, goal contents theory, and relational motivation theory. Following each section are preliminary suggestions about how each mini-theory might be useful or informative in other branches of personality. This special issue contains 9 articles, each of which makes its own attempt to newly link its area of personality research to SDT. Even if SDT is not the appropriate seed for greater consilience in personality psychology, we urge the field not to neglect the search for unifying principles (Sheldon, Chen, & Hilpert, 2011); it may finally be time to renew the search for a "grand theory" in personality.

Self-esteem is a potent indicator of mental health in typically developing (TYP) individuals. It is surprising that there have been few comprehensive investigations of self-esteem in children and adolescents with autism spectrum disorder (ASD), given that they are at high risk for comorbid mental health problems, such as depression and anxiety. The objectives of the current study were to assess how youth with ASD rate their self-esteem compared to age-matched TYP youth and to examine how self-esteem relates to internalizing psychopathology and theory of mind in the two groups. Seventy-three children and adolescents, ages 9 to 17, were administered a battery of questionnaires assessing self-esteem and internalizing symptoms, as well as tasks designed to measure theory of mind. Results indicated that youth with ASD rated their self-esteem significantly lower than did TYP youth. Self-esteem was strongly related to depression in both groups but was negatively related to theory of mind only for youth with ASD. These results may provide important insights into how individuals with ASD form evaluations of their own self-worth and illustrate how increasing self-awareness in individuals with ASD is not without risks.

We search for theories, in general spacetime dimensions, that would incorporate a dilaton and higher powers of the scalar Ricci curvature such that they have exact S- or T-self-dualities. The theories we find are free of Ostrogradsky instabilities. We also show that within the framework we are confining ourselves, a theory of the form mentioned above cannot have both T- and S-dualities except for the case where the action is linear in the scalar curvature.

Toward a cognitive-affective model of goal-setting in rehabilitation: is self-regulation theory a key step?

Science.gov (United States)

Siegert, Richard J; McPherson, Kathryn M; Taylor, William J

2004-10-21

The aim of this article is to argue that self-regulation theory might offer a useful model for clinical practice, theory-building and empirical research on goal-setting in rehabilitation. Relevant literature on goal-setting and motivation in rehabilitation is considered and some problematic issues for current practice and future research are highlighted. Carver and Scheier's self-regulation theory and its application to rehabilitation research is examined. It is argued that self-regulation theory offers a robust theoretical framework for goal-setting and one in which the salient concepts of motivation and emotion are prominent. Self-regulation theory offers a potentially useful heuristic framework for rehabilitation research.

Self-consistent theory of hadron-nucleus scattering. Application to pion physics

International Nuclear Information System (INIS)

Johnson, M.B.

1980-01-01

The requirement of using self-consistent amplitudes to evaluate microscopically the scattering of strongly interacting particles from nuclei is developed. Application of the idea to a simple model of pion-nucleus scattering is made. Numerical results indicate that the expansion of the optical potential converges when evaluated in terms of fully self-consistent quantities. A comparison of the results to a recent determination of the spreading interaction in the phenomenological isobar-hole model shows that the theory accounts for the sign and magnitude of the real and imaginary part of the spreading interaction with no adjusted parameters. The self-consistnt theory has a strong density dependence, and the consequences of this for pion-nucleus scattering are discussed. 18 figures, 1 table
Psychosomatic symptoms in medical outpatients: an investigation of self-handicapping theory.

Organista, P B; Miranda, J

1991-01-01

Investigated self-handicapping theory as it relates to somatization in medical patients. We predicted that medical outpatients (N = 113) would report psychosomatic symptoms in response to events that threaten their self-esteem. As predicted, results of hierarchical multiple regression indicated that high-perfectionism patients reported somatic symptoms positively related to the number of events that jeopardize their sense of accomplishment, whereas low-perfectionism patients' somatic symptoms were not related to these events (p = .005). Contrary to prediction, high-dependency patients did not differ significantly from low-dependency patients in the relationship of somatic symptoms and events that threatened their interpersonal relationships (p = .115). Implications of these findings and the utility of self-handicapping theory for predicting somatization in medical patients are discussed.
Self-organization theories and environmental management: The case of South Moresby, Canada

Science.gov (United States)

Grzybowski, Alex G. S.; Slocombe, D. Scott

1988-07-01

This article presents a new approach to the analysis and management of large-scale societal problems with complex ecological, economic, and social dimensions. The approach is based on the theory of self-organizing systems—complex, open, far-from-equilibrium systems with nonlinear dynamics. A brief overview and comparison of different self-organization theories (synergetics, self-organization theory, hypercycles, and autopoiesis) is presented in order to isolate the key characteristics of such systems. The approach is used to develop an analysis of the landuse controversy in the South Moresby area of the Queen Charlotte Islands, British Columbia, Canada. Critical variables are identified for each subsystem and classified by spatial and temporal scale, and discussed in terms of information content and internal/external origin. Eradication of sea otters, introduction of black-tailed deer, impacts of large-scale clearcut logging, sustainability of the coastal forest industry, and changing relations between native peoples and governments are discussed in detail to illustrate the system dynamics of the South Moresby “sociobiophysical” system. Finally, implications of the self-organizing sociobiophysical system view for regional analysis and management are identified.

Self-regulation is a complex multidimensional construct which has been approached mainly in Western cultural contexts. The present contribution examines the importance of considering the culture-sensitive nature of self-regulation by reviewing theory and research on the development of children’s self-regulation in different cultural contexts. This review of theory and research allows to suggest that widely shared values in a cultural group influence parental socialization theories, goals, and practices, which in turn have an impact on how children learn to self-regulate, the forms of self-regulation they develop, and the goals associated with self-regulation. Thus, this article concludes that more specific research is required to relate both the developmental and the cultural aspects of children’s self-regulation. PMID:28634460

This study introduces some theories and methods of self-organization system to the research of the diffusion mechanism of mass incidents in Weibo (Chinese Twitter). Based on the analysis on massive Weibo data from Songjiang battery factory incident happened in 2013 and Jiiangsu Qidong OJI PAPER incident happened in 2012, we find out that diffusion system of mass incident in Weibo satisfies Power Law, Zipf's Law, 1/f noise and Self-similarity. It means this system is the self-organization criticality system and dissemination bursts can be understood as one kind of Self-organization behavior. As the consequence, self-organized criticality (SOC) theory can be used to explain the evolution of mass incident diffusion and people may come up with the right strategy to control such kind of diffusion if they can handle the key ingredients of Self-organization well. Such a study is of practical importance which can offer opportunities for policy makers to have good management on these events.
Self-consistent field theory of collisions: Orbital equations with asymptotic sources and self-averaged potentials

Energy Technology Data Exchange (ETDEWEB)

Hahn, Y.K., E-mail: ykhahn22@verizon.net

The self-consistent field theory of collisions is formulated, incorporating the unique dynamics generated by the self-averaged potentials. The bound state Hartree–Fock approach is extended for the first time to scattering states, by properly resolving the principal difficulties of non-integrable continuum orbitals and imposing complex asymptotic conditions. The recently developed asymptotic source theory provides the natural theoretical basis, as the asymptotic conditions are completely transferred to the source terms and the new scattering function is made fullyintegrable. The scattering solutions can then be directly expressed in terms of bound state HF configurations, establishing the relationship between the bound and scattering state solutions. Alternatively, the integrable spin orbitals are generated by constructing the individual orbital equations that contain asymptotic sources and self-averaged potentials. However, the orbital energies are not determined by the equations, and a special channel energy fixing procedure is developed to secure the solutions. It is also shown that the variational construction of the orbital equations has intrinsic ambiguities that are generally associated with the self-consistent approach. On the other hand, when a small subset of open channels is included in the source term, the solutions are only partiallyintegrable, but the individual open channels can then be treated more simply by properly selecting the orbital energies. The configuration mixing and channel coupling are then necessary to complete the solution. The new theory improves the earlier continuum HF model. - Highlights: • First extension of HF to scattering states, with proper asymptotic conditions. • Orbital equations with asymptotic sources and integrable orbital solutions. • Construction of self-averaged potentials, and orbital energy fixing. • Channel coupling and configuration mixing, involving the new orbitals. • Critical evaluation of the
A Cognitive-Systemic Reconstruction of Maslow's Theory of Self-Actualization

OpenAIRE

Heylighen, Francis

1992-01-01

Maslow's need hierarchy and model of the self-actualizing personality are reviewed and criticized. The definition of self-actualization is found to be confusing, and the gratification of all needs is concluded to be insufficient to explain self-actualization. Therefore the theory is reconstructed on the basis of a second-order, cognitive-systemic framework. A hierarchy of basic needs is derived from the urgency of perturbations which an autonomous system must compensate in order to maintain i...

A self-consistent theory of the magnetic polaron

Marvakov, D.I.; Kuzemsky, A.L.; Vlahov, J.P.

1984-10-01

A finite temperature self-consistent theory of magnetic polaron in the s-f model of ferromagnetic semiconductors is developed. The calculations are based on the novel approach of the thermodynamic two-time Green function methods. This approach consists in the introduction of the ''irreducible'' Green functions (IGF) and derivation of the exact Dyson equation and exact self-energy operator. It is shown that IGF method gives a unified and natural approach for a calculation of the magnetic polaron states by taking explicitly into account the damping effects and finite lifetime. (author)
Self-recognition, theory-of-mind, and self-awareness: what side are you on?

Science.gov (United States)

Morin, Alain

2011-05-01

A fashionable view in comparative psychology states that primates possess self-awareness because they exhibit mirror self-recognition (MSR), which in turn makes it possible to infer mental states in others ("theory-of-mind"; ToM). In cognitive neuroscience, an increasingly popular position holds that the right hemisphere represents the centre of self-awareness because MSR and ToM tasks presumably increase activity in that hemisphere. These two claims are critically assessed here as follows: (1) MSR should not be equated with full-blown self-awareness, as it most probably only requires kinaesthetic self-knowledge and does not involve access to one's mental events; (2) ToM and self-awareness are fairly independent and should also not be taken as equivalent notions; (3) MSR and ToM tasks engage medial and left brain areas; (4) other self-awareness tasks besides MSR and ToM tasks (e.g., self-description, autobiography) mostly recruit medial and left brain areas; (5) and recent neuropsychological evidence implies that inner speech (produced by the left hemisphere) plays a significant role in self-referential activity. The main conclusions reached based on this analysis are that (a) organisms that display MSR most probably do not possess introspective self-awareness, and (b) self-related processes most likely engage a distributed network of brain regions situated in both hemispheres.

Implicit theories reflect core assumptions about whether human attributes are malleable or fixed: Incremental theorists believe a characteristic is malleable whereas entity theorists believe it is fixed. People with entity theories about health may be less likely to engage in risk-mitigating behavior. Spontaneous self-affirmation (e.g., reflecting on one's values when threatened) may lessen defensiveness and unhealthy behaviors associated with fixed beliefs, and reduce the likelihood of responding to health risk information with fixed beliefs. Across two studies conducted in the US from 2012 to 2015, we investigated how self-affirmation and implicit theories about health and body weight were linked to engagement with genetic risk information. In Study 1, participants in a genome sequencing trial (n = 511) completed cross-sectional assessments of implicit theories, self-affirmation, and intentions to learn, share, and use genetic information. In Study 2, overweight women (n = 197) were randomized to receive genetic or behavioral explanations for weight; participants completed surveys assessing implicit theories, self-affirmation, self-efficacy, motivation, and intentions. Fixed beliefs about weight were infrequently endorsed across studies (10.8-15.2%). In Study 1, participants with stronger fixed theories were less interested in learning and using genetic risk information about medically actionable disease; these associations were weaker among participants higher in self-affirmation. In Study 2, among participants given behavioral explanations for weight, stronger fixed theories about weight were associated with lower motivation and intentions to eat a healthy diet. Among participants given genetic explanations, being higher in self-affirmation was associated with less fixed beliefs. Stronger health-related fixed theories may decrease the likelihood of benefiting from genetic information, but less so for people who self-affirm. Published by Elsevier Ltd.

Parents of hospitalized children, especially parents of children with complex and chronic health conditions, report not being adequately prepared for self-management of their child's care at home after discharge. No theory-based discharge intervention exists to guide pediatric nurses' preparation of parents for discharge. To develop a theory-based conversation guide to optimize nurses' preparation of parents for discharge and self-management of their child at home following hospitalization. Two frameworks and one method influenced the development of the intervention: the Individual and Family Self-Management Theory, Tanner's Model of Clinical Judgment, and the Teach-Back method. A team of nurse scientists, nursing leaders, nurse administrators, and clinical nurses developed and field tested the electronic version of a nine-domain conversation guide for use in acute care pediatric hospitals. The theory-based intervention operationalized self-management concepts, added components of nursing clinical judgment, and integrated the Teach-Back method. Development of a theory-based intervention, the translation of theoretical knowledge to clinical innovation, is an important step toward testing the effectiveness of the theory in guiding clinical practice. Clinical nurses will establish the practice relevance through future use and refinement of the intervention. © 2017 Sigma Theta Tau International.

Self-knowledge and attribution of mental states in Theory of Mind

Directory of Open Access Journals (Sweden)

Skidelsky, Liza

2011-05-01

Full Text Available Many philosophers consider that self-knowledge reflects the particularity that we can know what we think, believe, desire, in a different way in which we know the mental states of other people. This is the claim of an asymmetry between first and third person. Several approaches han been offered in the epistemological literature in order to account for this asymmetry. Nonetheless, unlike the expected compatibility between adjacent fields, the literature related to the attribution and self-attribution of mental states or, in general, what is called Theory of Mind, does not seem either to preserve this asymmetry or the attempt to preserve it undermines the fundamental role of the different Theory of Mind proposals. This paper will show this in two parts. Firstly, it addresses how the asymmetry thesis han been defended in the epistemological literature. The aim of this section is to offer a geography of the different approaches. Secondly, two proposals in Theory of Mind, the theory theory and simulation theory, will be evaluated in order to show why they do not account for the asymmetry thesis, and some of the consequences that would be gather from the attempt to conciliate these Theory of Mind proposals with the epistemological approaches that defend the asymmetry thesis will be analized.

Self-Reorientation Following Colorectal Cancer Treatment - A Grounded Theory Study.

Johansson, Ann-Caroline B; Axelsson, Malin; Berndtsson, Ina; Brink, Eva

2015-01-01

After colorectal cancer (CRC) treatment, people reorganize life in ways that are consistent with their understanding of the illness and their expectations for recovery. Incapacities and abilities that have been lost can initiate a need to reorient the self. To the best of our knowledge, no studies have explicitly focused on the concept of self-reorientation after CRC treatment. The aim of the present study was therefore to explore self-reorientation in the early recovery phase after CRC surgery. Grounded theory analysis was undertaken, using the method presented by Charmaz. The present results explained self-reorientation as the individual attempting to achieve congruence in self-perception. A congruent self-perception meant bringing together the perceived self and the self that was mirrored in the near environs. The results showed that societal beliefs and personal explanations are essential elements of self-reorientation, and that it is therefore important to make them visible.

This study applies the self-determination theory (SDT) to test the hypothesized relationships among perceived autonomy support from parents, physical education (PE) teachers, and peers, the fulfilment of psychological needs (i.e., autonomy, competence, and relatedness), autonomous motivation, and leisure-time physical activity of Chinese adolescents. There are 255 grade six to eight student participants from four middle schools around Shanghai, China included in this study. An accelerometer was used to measure the moderate-to-vigorous physical activity (MVPA). The participants completed the questionnaires regarding SDT variables. The structural equation modelling was applied to examine the hypothesized relationships among the study variables. The model of hypothesized relationships demonstrated a good fit with the data [X 2 = 20.84, df = 9, P = .01; CFI = 0.98; IFI = 0.98; SRMR = 0.04; RMSEA = 0.05]. The findings revealed that autonomy support from parents, PE teachers, and peers foster social conditions in which the three basic psychological needs can be met. In turn, autonomy, competence, and relatedness are positively associated with autonomous motivation for MVPA. The autonomous motivation positively relates to the MVPA time of adolescents. The three psychological needs partially mediate the influence of autonomy support from parents (β = 0.18, P motivation. In conclusion, these findings support the applicability of SDT in understanding and promoting physical activity of Chinese adolescents.
Professional virtue and professional self-awareness: a case study in engineering ethics.

Science.gov (United States)

Stovall, Preston

2011-03-01

This paper articulates an Aristotelian theory of professional virtue and provides an application of that theory to the subject of engineering ethics. The leading idea is that Aristotle's analysis of the definitive function of human beings, and of the virtues humans require to fulfill that function, can serve as a model for an analysis of the definitive function or social role of a profession and thus of the virtues professionals must exhibit to fulfill that role. Special attention is given to a virtue of professional self-awareness, an analogue to Aristotle's phronesis or practical wisdom. In the course of laying out my account I argue that the virtuous professional is the successful professional, just as the virtuous life is the happy life for Aristotle. I close by suggesting that a virtue ethics approach toward professional ethics can enrich the pedagogy of professional ethics courses and help foster a sense of pride and responsibility in young professionals.

2009-05-01

To explore conceptual links between the cognitive-motivational-relational theory (CMRT) of coping (Lazarus, 1991) and self-determination theory (SDT) of motivation (Deci & Ryan, 1985). We present a very brief overview of the two theories. We also discuss how components from the two theories can be examined together to facilitate research in the health/exercise domain. To this effect, we offer a preliminary integrated model of stress, coping, and motivation, based on the two aforementioned theories, in an attempt to illustrate and instigate research on how motivational factors are implicated in the coping process. We believe that the proposed model can serve as a platform for generating new research ideas which, besides their theoretical relevance, may have important applied implications.
Renormalization in self-consistent approximation schemes at finite temperature I: theory

International Nuclear Information System (INIS)

Hees, H. van; Knoll, J.

2001-07-01

Within finite temperature field theory, we show that truncated non-perturbative self-consistent Dyson resummation schemes can be renormalized with local counter-terms defined at the vacuum level. The requirements are that the underlying theory is renormalizable and that the self-consistent scheme follows Baym's Φ-derivable concept. The scheme generates both, the renormalized self-consistent equations of motion and the closed equations for the infinite set of counter terms. At the same time the corresponding 2PI-generating functional and the thermodynamic potential can be renormalized, in consistency with the equations of motion. This guarantees the standard Φ-derivable properties like thermodynamic consistency and exact conservation laws also for the renormalized approximation scheme to hold. The proof uses the techniques of BPHZ-renormalization to cope with the explicit and the hidden overlapping vacuum divergences. (orig.)
The Measurement, Nomological Net, and Theory of Perceived Self-Esteem Instability: Applying the Conservation of Resources Theory to Understand the Construct.

Science.gov (United States)

Howard, Matt C

2018-01-01

The current article performs the first focused investigation into the construct of perceived self-esteem instability (P-SEI). Four studies investigate the construct's measurement, nomological net, and theoretical dynamics. Study 1 confirms the factor structure of a P-SEI Measure, supporting that P-SEI can be adequately measured. Study 2 identifies an initial nomological net surrounding P-SEI, showing that the construct is strongly related to stable aspects of the self (i.e., neuroticism and core self-evaluations). In Studies 3 and 4, the Conservation of Resources Theory is applied to develop and test five hypotheses. These studies show that P-SEI is predicted by self-esteem level and stressors, and the relationship of certain stressors is moderated by self-esteem contingencies. P-SEI also predicts stress, depression, anxiety, and certain defensive postures. From these studies and the integration of Conservation of Resources Theory, we suggest that P-SEI emerges through an interaction between environmental influences and personal resources, and we provide a theoretical model to better understand the construct of P-SEI. We suggest that this theory-driven model can prompt the initial field of study on P-SEI.
Investigating the importance of self-theories of intelligence and musicality for students' academic and musical achievement.

Musical abilities and active engagement with music have been shown to be positively associated with many cognitive abilities as well as social skills and academic performance in secondary school students. While there is evidence from intervention studies that musical training can be a cause of these positive relationships, recent findings in the literature have suggested that other factors, such as genetics, family background or personality traits, might also be contributing factors. In addition, there is mounting evidence that self-concepts and beliefs can affect academic performance independently of intellectual ability. Students who believe that intelligence is malleable are more likely to attribute poor academic performances to effort rather than ability, and are more likely to take remedial action to improve their performance. However, it is currently not known whether student's beliefs about the nature of musical talent also influence the development of musical abilities in a similar fashion. Therefore, this study introduces a short self-report measure termed "Musical Self-Theories and Goals," closely modeled on validated measures for self-theories in academic scenarios. Using this measure the study investigates whether musical self-theories are related to students' musical development as indexed by their concurrent musical activities and their performance on a battery of listening tests. We use data from a cross-sectional sample of 313 secondary school students to construct a network model describing the relationships between self-theories and academic as well as musical outcome measures, while also assessing potential effects of intelligence and the Big Five personality dimensions. Results from the network model indicate that self-theories of intelligence and musicality are closely related. In addition, both kinds of self-theories are connected to the students' academic achievement through the personality dimension conscientiousness and academic effort

From Self to Nonself: The Nonself Theory

Science.gov (United States)

Shiah, Yung-Jong

2016-01-01

The maintenance/strength of self is a very core concept in Western psychology and is particularly relevant to egoism, a process that draws on the hedonic principle in pursuit of desires. Contrary to this and based on Buddhism, a nonself-cultivating process aims to minimize or extinguish the self and avoid desires, leading to egolessness or selflessness. The purpose of this paper is to present the Nonself Theory (NT). The universal Mandala Model of Self (MMS) was developed to describe the well-functioning self in various cultures. The end goal of the self is to attain authentic and durable happiness. Given that the nonself is considered a well-functioning self, the MMS is suitable for constructing the NT. The ego and nonself aspects of psychological self-functioning and their underlying processes are compared, drawing on the four concepts of the MMS: biology, ideal person, knowledge/wisdom and action. The ego engages in psychological activities to strengthen the self, applying the hedonic principle of seeking desire-driven pleasure. In contrast, a nonself approach involves execution of the self-cultivation principle, which involves three ways: giving up desires, displaying compassion, practicing meditation and seeking understanding Buddhist wisdom. These three ways have the goal of seeing through and overcoming the illusion of the self to achieve a deep transformation integrally connected to the experience of eliminating the sense of self and its psychological structures. In addition, the NT provides a comprehensive framework to account for nonself-plus-compassion-related activities or experiences such as altruism, mindfulness, mediation, mysterious/peak experiences, elimination of death anxiety and moral conduct. The NT offers possible answers that might lead to a more comprehensive understanding of human beings and the deeper meaning of life, toward the ultimate goal of a well-functioning self.

Self-management programs based on social cognitive theory are useful to improve health care outcomes for patients with chronic diseases in Western culture. The purpose of this review is to identify and synthesize published research on the theory to enhance self-efficacy in disease management and examine its applicability to Korean culture regarding the learning strategies used. Ultimately, it was to identify the optimal use of these learning strategies to improve the self-efficacy of Korean patients in self-management of their hypertension and diabetic mellitus. The authors searched the Korean and international research databases from January 2000 to September 2009. Twenty studies were selected and reviewed. The most frequently used learning strategies of social cognitive theory was skill mastery by practice and feedback (N = 13), followed by social or verbal persuasion by group members (N = 7) and, however, observation learning and reinterpretation of symptoms by debriefing or discussion were not used any of the studies. Eight studies used only one strategy to enhance self-efficacy and six used two. A lack of consistency regarding the content and clinical efficacy of the self-efficacy theory-based self-management programs is found among the reviewed studies on enhancing self-efficacy in Koreans with hypertension and diabetes mellitus. Further research on the effectiveness of these theory-based self-management programs for patients with chronic diseases in Korea and other countries is recommended.

We searched electronic databases PubMed, PsycINFO, CENTRAL, and EMBASE from inception to May 2014. We searched clinicaltrials.gov for registered protocols, reference lists of relevant systematic reviews and included studies, and conducted a citation search in Web of Science. We included peer-reviewed publications of interventions that referenced the social cognitive theory of self-regulation as a framework for interventions to manage chronic health conditions. Two reviewers independently assessed articles for eligibility. We contacted all authors of included studies for information detailing intervention content. We describe how often theory mechanisms were addressed by interventions, and report intervention characteristics used to address theory.Of 202 articles that reported using the social cognitive theory of self-regulation, 52% failed to incorporate self-monitoring, a main theory component, and were therefore excluded. We included 35 interventions that adequately used the theory framework. Intervention characteristics were often poorly reported in peer-reviewed publications, 21 of 35 interventions incorporated characteristics that addressed each of the main theory components. Each intervention addressed, on average, six of eight self-monitoring mechanisms, two of five self-judgement mechanisms, and one of three self-evaluation mechanisms.

In contrast, a nonself approach involves execution of the self-cultivation principle, which involves three ways: giving up desires, displaying compassion, practicing meditation and seeking understanding Buddhist wisdom. These three ways have the goal of seeing through and overcoming the illusion of the self to achieve a deep transformation integrally connected to the experience of eliminating the sense of self and its psychological structures. In addition, the NT provides a comprehensive framework to account for nonself-plus-compassion-related activities or experiences such as altruism, mindfulness, mediation, mysterious/peak experiences, elimination of death anxiety and moral conduct. The NT offers possible answers that might lead to a more comprehensive understanding of human beings and the deeper meaning of life, toward the ultimate goal of ultimate wholeness. An
Treatise on intuitionistic type theory

CERN Document Server

Intuitionistic type theory can be described, somewhat boldly, as a fulfillment of the dream of a universal language for science. In particular, intuitionistic type theory is a foundation for mathematics and a programming language.
The impact of Einsteinian relativity and quantum physics theories on conceptualizations of the self in psychology

Science.gov (United States)

Rechberger, Elke Ruth

1999-11-01

Prior to the 1600s c.e., the church was the final authority for theories about the universe and humanity's role within it. However, when the mathematical theories put forth by scientists such as Copernicus and Galileo refuted traditional theological explanations about the cosmos, a shift to science as the premiere authority for theories was established, a tradition which continues to this day. In the following century, the work of Newton set forth a theory of the universe operating as a machine, where all things were potentially knowable, measurable, and predictable. His mechanistic hypotheses helped substantiate a corollary philosophy known as modernism. In the early 1900s, Einstein's theories about light and relativity began to indicate a universe significantly less absolute. His work set the stage for the development of quantum physics theories, whose hallmarks are probability, uncertainty, and complementarity. Quantum physics theories helped substantiate the philosophy known as postmodernism, where truth is nonexistent, reality is a subjectively constructed phenomenon, and the concept of an individual self is considered an illusion. Given that developments in physics have had profound impact across academic disciplines, including psychology, this study examine the effect of major revolutions in physics to corollary developments in theories about the self in psychology. It is the assertion of this work that modernist conceptualization of the self is one that is highly individualistic and defined in mechanistic terms, whereas the postmodern conceptualization of the self is significantly more socially constructed and has more interpersonally fluid, amorphous boundaries. Implications for conceptualizations of the self from either the modern or postmodern paradigm are discussed, as well as suggestions for future theory development.

Protection is as important as other basic needs as it ensures the continuity of the fulfillment of the needs. The fulfillment from Islamic point of view can be categorised into five major areas as prescribed under the Maqasid al-Shariah. Protection can be achieved via Insurance, but it is not acceptable by Islam because of the element of riba, gharar, and maysir in it. Therefore, Takaful or Islamic Insurance is taken as alternative to achieve the same objective but with a different contract a...

Ego depletion--is it all in your head? implicit theories about willpower affect self-regulation.

Science.gov (United States)

Job, Veronika; Dweck, Carol S; Walton, Gregory M

2010-11-01

Much recent research suggests that willpower--the capacity to exert self-control--is a limited resource that is depleted after exertion. We propose that whether depletion takes place or not depends on a person's belief about whether willpower is a limited resource. Study 1 found that individual differences in lay theories about willpower moderate ego-depletion effects: People who viewed the capacity for self-control as not limited did not show diminished self-control after a depleting experience. Study 2 replicated the effect, manipulating lay theories about willpower. Study 3 addressed questions about the mechanism underlying the effect. Study 4, a longitudinal field study, found that theories about willpower predict change in eating behavior, procrastination, and self-regulated goal striving in depleting circumstances. Taken together, the findings suggest that reduced self-control after a depleting task or during demanding periods may reflect people's beliefs about the availability of willpower rather than true resource depletion.

A BCM theory of meta-plasticity for online self-reorganizing fuzzy-associative learning.

Science.gov (United States)

Tan, Javan; Quek, Chai

2010-06-01

Self-organizing neurofuzzy approaches have matured in their online learning of fuzzy-associative structures under time-invariant conditions. To maximize their operative value for online reasoning, these self-sustaining mechanisms must also be able to reorganize fuzzy-associative knowledge in real-time dynamic environments. Hence, it is critical to recognize that they would require self-reorganizational skills to rebuild fluid associative structures when their existing organizations fail to respond well to changing circumstances. In this light, while Hebbian theory (Hebb, 1949) is the basic computational framework for associative learning, it is less attractive for time-variant online learning because it suffers from stability limitations that impedes unlearning. Instead, this paper adopts the Bienenstock-Cooper-Munro (BCM) theory of neurological learning via meta-plasticity principles (Bienenstock et al., 1982) that provides for both online associative and dissociative learning. For almost three decades, BCM theory has been shown to effectively brace physiological evidence of synaptic potentiation (association) and depression (dissociation) into a sound mathematical framework for computational learning. This paper proposes an interpretation of the BCM theory of meta-plasticity for an online self-reorganizing fuzzy-associative learning system to realize online-reasoning capabilities. Experimental findings are twofold: 1) the analysis using S&P-500 stock index illustrated that the self-reorganizing approach could follow the trajectory shifts in the time-variant S&P-500 index for about 60 years, and 2) the benchmark profiles showed that the fuzzy-associative approach yielded comparable results with other fuzzy-precision models with similar online objectives.
The relationship between epistemological beliefs, implicit theories of intelligence, and self-regulated learning among Norwegian postsecondary students.

Science.gov (United States)

Bråten, Ivar; Strømsø, Helge I

2005-12-01

More empirical work is needed to examine the dimensionality of personal epistemology and relations between those dimensions and motivational and strategic components of self-regulated learning. In particular, there is great need to investigate personal epistemology and its relation to self-regulated learning across cultures and academic contexts. Because the demarcation between personal epistemology and implicit theories of intelligence has been questioned, dimensions of personal epistemology should also be studied in relation to implicit theories of intelligence. The primary aim was to examine the dimensionality of personal epistemology and the relation between those dimensions and implicit theories of intelligence in the cultural context of Norwegian postsecondary education. A secondary aim was to examine the relative contribution of epistemological beliefs and theories of intelligence to motivational and strategic components of self-regulated learning in different academic contexts within that culture. The first sample included 178 business administration students in a traditional transmission-oriented instructional context; the second, 108 student teachers in an innovative pedagogical context. The dimensionality of the Schommer Epistemological Questionnaire was examined through factor analyses, and the resulting dimensions were examined in relation to implicit theories of intelligence. We performed multiple regression analyses, separately for the two academic contexts, to try to predict motivational (i.e. self-efficacy beliefs, mastery goal orientation, and interest) and strategic (i.e. self-regulatory strategy use) components of self-regulated learning with epistemological beliefs and implicit theories of intelligence. Considerable cross-cultural generalizability was found for the dimensionality of personal epistemology. Moreover, the dimensions of personal epistemology seemed to represent constructs separate from the construct of implicit theories of

The middle-range nursing theory of self-transcendence may be applicable to individuals in the early stages of Alzheimer's disease. Full cognitive ability may not be necessary for the essential principles of this theory to be implemented. The theory can offer guidance to families and health care providers in attempting to facilitate a meaningful aging process. A case scenario of an elderly woman with Alzheimer's disease demonstrates how family and caregivers can initiate interventions based on the theoretical concepts. © The Author(s) 2014.
The relationship of self-regulation and aggression: an empirical test of personality systems interaction theory.

Science.gov (United States)

Ross, Thomas; Fontao, María Isabel

2008-10-01

On the basis of personality systems interaction (PSI) theory, the authors examine self-regulation, conflict behaviour, behavioural resources, and personality disorders in a sample of 83 male offenders and explore the role self-regulatory variables play with respect to aggressive behaviour. Although substantial correlations between self-regulatory functions and aggressive behaviour were found, these variables did not predict aggression in a subsequent regression analysis with measures of self-regulation, conflict behaviour, and personality disorders as independent variables. Antisocial behaviour, behavioural self-control, and affect were among the strongest predictors of aggression. Specific predictions based on PSI theory could not be confirmed. Theoretical implications of the findings are discussed and put into relation with treatment issues of offenders.

Dispersion relations for the self-energy in noncommutative field theories

International Nuclear Information System (INIS)

Brandt, F.T.; Das, Ashok; Frenkel, J.

2002-01-01

We study the IR-UV connection in noncommutative φ 3 theory as well as in noncommutative QED from the point of view of the dispersion relation for self-energy. We show that, although the imaginary part of the self-energy is well behaved as the parameter of noncommutativity vanishes, the real part becomes divergent as a consequence of the high energy behavior of the dispersion integral. Some other interesting features that arise from this analysis are also briefly discussed
The myth of ability nurturing mathematical talent in every child

CERN Document Server

Mighton, John

2004-01-01

For decades teachers and parents have accepted the judgment that some students just aren’t good at math. John Mighton—the founder of a revolutionary math program designed to help failing math students—feels that not only is this wrong, but that it has become a self-fulfilling prophecy. A pioneering educator, Mighton realized several years ago that children were failing math because they had come to believe they were not good at it. Once students lost confidence in their math skills and fell behind, it was very difficult for them to catch up, particularly in the classroom. He knew this from experience, because he had once failed math himself. Using the premise that anyone can learn math and anyone can teach it, Mighton’s unique teaching method isolates and describes concepts so clearly that students of all skill levels can understand them. Rather than fearing failure, students learn from and build on their own successes and gain the confidence and self-esteem they need to be inspired to learn. Might...
High-temperature expansion along the self-dual line of three-dimensional Z(2) spin-gauge theory

International Nuclear Information System (INIS)

Bhanot, G.

1981-01-01

We exploit the self-duality of the three-dimensional Ising spin-gauge theory to develop an eighth-order high-temperature expansion for the partition function along the self-dual line. This generates a high-temperature series for the gauge-invariant, nearest-neighbor spin-spin correlation function. A Pade analysis of this series reveals a pole along the self-dual line. Recent Monte Carlo simulations indicate that this theory has a first-order self-dual line emerging from a triple point. We interpret the Pade pole as a theoretical estimate of the end point of this self-dual line
An Examination of the Four-Part Theory of the Chinese Self: The Differentiation and Relative Importance of the Different Types of Social-Oriented Self.

Science.gov (United States)

Sun, Chien-Ru

2017-01-01

Because culture has a deep and far-reaching influence, individuals who grew up within different cultures tend to develop different basic self-constructions. With respect to the Chinese under the influence of Chinese culture, Yang proposed the concepts of individual-oriented self and social-oriented self. He argued that, besides the individual-oriented self, the social-oriented self of the Chinese contains three types of self: the relationship-oriented self, the familistic (group)-oriented self, and the other-oriented self. The theory proposed that the Chinese self is appropriately covered only through this four-part theory of the Chinese self. However, this remains to be tested; whether these three types of sub-level "selves" can be effectively triggered, along with their relative importance. This study examines the four-part theory of the Chinese self. Through photo priming, Experiment 1 shows that the three types of social-oriented self are differentiated from each other and can be individually triggered. In Experiment 2, the importance of the three types of self was investigated, adopting the concept of limited self-regulation resources to design scenarios. The participants were asked to make counterarguments about the notion of each of the three types of self, with performance in the subsequent task serving as the main dependent variable. In Experiment 3, the relative importance of the three types of self was examined by investigating the choices made by individuals within the context of conflict under the three orientations of the social-oriented self. Overall, results of the experiments showed that the Chinese have a four-part self with the importance of the other-oriented self as the most remarkable.

2006-10-01

Using self-determination theory, two studies investigated the relations among perceived need support from parents, their adolescents' autonomous self-regulation for academics, and the adolescents' well-being. Study 1 indicated that perceived need support from parents independently predicted adolescents' well-being, although when mothers' and fathers' data were examined separately, the relation was stronger for mothers than for fathers. In Study 2, autonomous self-regulation for planning to attend college was a significant partial mediator of the relation of adolescents' perceived need support to well-being. Thus, perceived need support from parents does seem important for the development of adolescents' autonomous self-regulation and well-being.
Self-Organized Complexity and Coherent Infomax from the Viewpoint of Jaynes’s Probability Theory

Directory of Open Access Journals (Sweden)

William A. Phillips

2012-01-01

Full Text Available This paper discusses concepts of self-organized complexity and the theory of Coherent Infomax in the light of Jaynes’s probability theory. Coherent Infomax, shows, in principle, how adaptively self-organized complexity can be preserved and improved by using probabilistic inference that is context-sensitive. It argues that neural systems do this by combining local reliability with flexible, holistic, context-sensitivity. Jaynes argued that the logic of probabilistic inference shows it to be based upon Bayesian and Maximum Entropy methods or special cases of them. He presented his probability theory as the logic of science; here it is considered as the logic of life. It is concluded that the theory of Coherent Infomax specifies a general objective for probabilistic inference, and that contextual interactions in neural systems perform functions required of the scientist within Jaynes’s theory.
Time-dependent restricted-active-space self-consistent-field theory for bosonic many-body systems

International Nuclear Information System (INIS)

Lévêque, Camille; Madsen, Lars Bojer

2017-01-01

We develop an ab initio time-dependent wavefunction based theory for the description of a many-body system of cold interacting bosons. Like the multi-configurational time-dependent Hartree method for bosons (MCTDHB), the theory is based on a configurational interaction Ansatz for the many-body wavefunction with time-dependent self-consistent-field orbitals. The theory generalizes the MCTDHB method by incorporating restrictions on the active space of the orbital excitations. The restrictions are specified based on the physical situation at hand. The equations of motion of this time-dependent restricted-active-space self-consistent-field (TD-RASSCF) theory are derived. The similarity between the formal development of the theory for bosons and fermions is discussed. The restrictions on the active space allow the theory to be evaluated under conditions where other wavefunction based methods due to exponential scaling in the numerical effort cannot, and to clearly identify the excitations that are important for an accurate description, significantly beyond the mean-field approach. For ground state calculations we find it to be important to allow a few particles to have the freedom to move in many orbitals, an insight facilitated by the flexibility of the restricted-active-space Ansatz . Moreover, we find that a high accuracy can be obtained by including only even excitations in the many-body self-consistent-field wavefunction. Time-dependent simulations of harmonically trapped bosons subject to a quenching of their noncontact interaction, show failure of the mean-field Gross-Pitaevskii approach within a fraction of a harmonic oscillation period. The TD-RASSCF theory remains accurate at much reduced computational cost compared to the MCTDHB method. Exploring the effect of changes of the restricted-active-space allows us to identify that even self-consistent-field excitations are mainly responsible for the accuracy of the method. (paper)

We apply BRST method to the self-dual Chern-Simons gauge theory with matter fields and the generators of symmetries of the system from an elegant Lie algebra structure under the operation of Poisson bracket. We discuss four different cases: abelian, nonabelian, relativistic, and nonrelativistic situations and extend the system to the whole phase space including ghost fields. In addition, we obtain the BRST charge of the field system and check its nilpotence of the BRST transformation which plays an important role such as in topological quantum field theory and string theory.
Correlates and consequences of parent-teen incongruence in reports of teens' sexual experience.

Mollborn, Stefanie; Everett, Bethany

2010-07-01

Using the National Longitudinal Study of Adolescent Health, factors associated with incongruence between parents' and adolescents' reports of teens' sexual experience were investigated, and the consequences of inaccurate parental knowledge for adolescents' subsequent sexual behaviors were explored. Most parents of virgins accurately reported teens' lack of experience, but most parents of teens who had had sex provided inaccurate reports. Binary logistic regression analyses showed that many adolescent-, parent-, and family-level factors predicted the accuracy of parents' reports. Parents' accurate knowledge of their teens' sexual experience was not found to be consistently beneficial for teens' subsequent sexual outcomes. Rather, parents' expectations about teens' sexual experience created a self-fulfilling prophecy, with teens' subsequent sexual outcomes conforming to parents' expectations. These findings suggest that research on parent-teen communication about sex needs to consider the expectations being expressed, as well as the information being exchanged.

Students' autonomy and teacher's interpersonal style in self-determination theory

Directory of Open Access Journals (Sweden)

Lalić-Vučetić Nataša

2009-01-01

Full Text Available Starting from psychological needs that are considered basic within self-determination theory (autonomy, competence and relatedness, the importance of encouraging students' autonomy in school context is particularly emphasised. Appreciation of students' autonomy has a stimulating effect on school achievement, conceptual understanding, creativity development, strengthening of self-esteem, and students adapt better to school system and demonstrate a larger degree of internalisation of school rules and intrinsic motivation. Teachers' behavioural style largely determines the degree of students' autonomy in school life and work. Self-determination theory implies the necessity of agreement between the developmental need for autonomy in children and the level of adult control and distinguishes between two styles of interpersonal behavior of teachers: (a those who offer support to students' autonomy by their behavior and (b those that are predominantly inclined to control students' behavior. This paper also points out to different strategies that can be applied by teachers in working with students in school, which also contribute to the development of students' autonomy. What is especially encouraging is the fact that it is possible to learn and to develop 'appreciation of students' autonomy' as teacher's interpersonal style.

On a gauge theory of the self-dual field and its quantization

International Nuclear Information System (INIS)

Srivastava, P.P.

1990-01-01

A gauge theory of self-dual fields is constructed by adding a Wess-Zumino term to the recently studied formulation based on a second-order scalar field lagrangian carrying with it an auxiliary vector field to take care of the self-duality constraint in a linear fashion. The two versions are quantized using the BRST formulation following the BFV procedure. No violation of microcausality occurs and the action of the ordinary scalar field may not be written as the sum of the actions of the self- and anti-self-dual fields. (orig.)
Building polyhedra by self-assembly: theory and experiment.

Kaplan, Ryan; Klobušický, Joseph; Pandey, Shivendra; Gracias, David H; Menon, Govind

2014-01-01

We investigate the utility of a mathematical framework based on discrete geometry to model biological and synthetic self-assembly. Our primary biological example is the self-assembly of icosahedral viruses; our synthetic example is surface-tension-driven self-folding polyhedra. In both instances, the process of self-assembly is modeled by decomposing the polyhedron into a set of partially formed intermediate states. The set of all intermediates is called the configuration space, pathways of assembly are modeled as paths in the configuration space, and the kinetics and yield of assembly are modeled by rate equations, Markov chains, or cost functions on the configuration space. We review an interesting interplay between biological function and mathematical structure in viruses in light of this framework. We discuss in particular: (i) tiling theory as a coarse-grained description of all-atom models; (ii) the building game-a growth model for the formation of polyhedra; and (iii) the application of these models to the self-assembly of the bacteriophage MS2. We then use a similar framework to model self-folding polyhedra. We use a discrete folding algorithm to compute a configuration space that idealizes surface-tension-driven self-folding and analyze pathways of assembly and dominant intermediates. These computations are then compared with experimental observations of a self-folding dodecahedron with side 300 μm. In both models, despite a combinatorial explosion in the size of the configuration space, a few pathways and intermediates dominate self-assembly. For self-folding polyhedra, the dominant intermediates have fewer degrees of freedom than comparable intermediates, and are thus more rigid. The concentration of assembly pathways on a few intermediates with distinguished geometric properties is biologically and physically important, and suggests deeper mathematical structure.
Self-consistent generalized Langevin-equation theory for liquids of nonspherically interacting particles

Science.gov (United States)

Elizondo-Aguilera, L. F.; Zubieta Rico, P. F.; Ruiz-Estrada, H.; Alarcón-Waess, O.

2014-11-01

A self-consistent generalized Langevin-equation theory is proposed to describe the self- and collective dynamics of a liquid of linear Brownian particles. The equations of motion for the spherical harmonics projections of the collective and self-intermediate-scattering functions, Fl m ,l m(k ,t ) and Flm ,l m S(k ,t ) , are derived as a contraction of the description involving the stochastic equations of the corresponding tensorial one-particle density nl m(k ,t ) and the translational (α =T ) and rotational (α =R ) current densities jlm α(k ,t ) . Similar to the spherical case, these dynamic equations require as an external input the equilibrium structural properties of the system contained in the projections of the static structure factor, denoted by Sl m ,l m(k ) . Complementing these exact equations with simple (Vineyard-like) approximate relations for the collective and the self-memory functions we propose a closed self-consistent set of equations for the dynamic properties involved. In the long-time asymptotic limit, these equations become the so-called bifurcation equations, whose solutions (the nonergodicity parameters) can be written, extending the spherical case, in terms of one translational and one orientational scalar dynamic order parameter, γT and γR, which characterize the possible dynamical arrest transitions of the system. As a concrete illustrative application of this theory we determine the dynamic arrest diagram of the dipolar hard-sphere fluid. In qualitative agreement with mode coupling theory, the present self-consistent equations also predict three different regions in the state space spanned by the macroscopic control parameters η (volume fraction) and T* (scaled temperature): a region of fully ergodic states, a region of mixed states, in which the translational degrees of freedom become arrested while the orientational degrees of freedom remain ergodic, and a region of fully nonergodic states.

Self-consistent generalized Langevin-equation theory for liquids of nonspherically interacting particles.

A self-consistent generalized Langevin-equation theory is proposed to describe the self- and collective dynamics of a liquid of linear Brownian particles. The equations of motion for the spherical harmonics projections of the collective and self-intermediate-scattering functions, F_{lm,lm}(k,t) and F_{lm,lm}^{S}(k,t), are derived as a contraction of the description involving the stochastic equations of the corresponding tensorial one-particle density n_{lm}(k,t) and the translational (α=T) and rotational (α=R) current densities j_{lm}^{α}(k,t). Similar to the spherical case, these dynamic equations require as an external input the equilibrium structural properties of the system contained in the projections of the static structure factor, denoted by S_{lm,lm}(k). Complementing these exact equations with simple (Vineyard-like) approximate relations for the collective and the self-memory functions we propose a closed self-consistent set of equations for the dynamic properties involved. In the long-time asymptotic limit, these equations become the so-called bifurcation equations, whose solutions (the nonergodicity parameters) can be written, extending the spherical case, in terms of one translational and one orientational scalar dynamic order parameter, γ_{T} and γ_{R}, which characterize the possible dynamical arrest transitions of the system. As a concrete illustrative application of this theory we determine the dynamic arrest diagram of the dipolar hard-sphere fluid. In qualitative agreement with mode coupling theory, the present self-consistent equations also predict three different regions in the state space spanned by the macroscopic control parameters η (volume fraction) and T* (scaled temperature): a region of fully ergodic states, a region of mixed states, in which the translational degrees of freedom become arrested while the orientational degrees of freedom remain ergodic, and a region of fully nonergodic states.

Self-immolation is a common method of suicide among Iranian women. There are several contributing motives for attempting self-immolation, and exploration of the process of self-immolation incidents will help interventionists and clinicians develop prevention programs. A grounded theory study using face-to-face, recorded interviews was conducted with surviving self-immolated patients (n=14), their close relatives (n=5), and medical staff (n=8) in Kermanshah, Iran. Data were analyzed using constant comparison in open, axial, and selective coding stages. A conceptual model was developed to explain the relationships among the main categories extracted through the grounded theory study. Family conflicts emerged as the core category. Cultural context of self-immolated patients offered a contextual condition. Other important categories linked to the core category were mental health problems, distinct characteristics of the suicidal method, and self-immolation as a threat. The role of mental health problems as a causal condition was detected in different levels of the self-immolation process. Finally, adverse consequences of self-immolation emerged as having important impact. The conceptual model, derived through grounded theory study, can guide design of prevention programs. The pivotal role of family conflicts should be emphasized in mental health interventions. The impact of adverse consequences of self-immolation on further suicidal processes necessitates post-suicide prevention programs. Further research to design specific interventions is recommended.

Quality of Life Theory II. Quality of Life as the Realization of Life Potential: A Biological Theory of Human Being

Directory of Open Access Journals (Sweden)

Soren Ventegodt

2003-01-01

Full Text Available This review presents one of the eight theories of the quality of life (QOL used for making the SEQOL (self-evaluation of quality of life questionnaire or the quality of life as realizing life potential. This theory is strongly inspired by Maslow and the review furthermore serves as an example on how to fulfill the demand for an overall theory of life (or philosophy of life, which we believe is necessary for global and generic quality-of-life research.Whereas traditional medical science has often been inspired by mechanical models in its attempts to understand human beings, this theory takes an explicitly biological starting point. The purpose is to take a close view of life as a unique entity, which mechanical models are unable to do. This means that things considered to be beyond the individual's purely biological nature, notably the quality of life, meaning in life, and aspirations in life, are included under this wider, biological treatise. Our interpretation of the nature of all living matter is intended as an alternative to medical mechanism, which dates back to the beginning of the 20th century. New ideas such as the notions of the human being as nestled in an evolutionary and ecological context, the spontaneous tendency of self-organizing systems for realization and concord, and the central role of consciousness in interpreting, planning, and expressing human reality are unavoidable today in attempts to scientifically understand all living matter, including human life.

Non-Gaussian path integration in self-interacting scalar field theories

International Nuclear Information System (INIS)

Kaya, Ali

2004-01-01

In self-interacting scalar field theories kinetic expansion is an alternative way of calculating the generating functional for Green's functions where the zeroth order non-Gaussian path integral becomes diagonal in x-space and reduces to the product of an ordinary integral at each point which can be evaluated exactly. We discuss how to deal with such functional integrals and propose a new perturbative expansion scheme which combines the elements of the kinetic expansion with the usual perturbation theory techniques. It is then shown that, when the cutoff dependences of the bare parameters in the potential are chosen to have a well defined non-Gaussian path integral without the kinetic term, the theory becomes trivial in the continuum limit

Two-particle self-consistent approach to unconventional superconductivity

2013-07-01

A non-perturbative approach to unconventional superconductivity is developed based on the idea of the two-particle self-consistent (TPSC) theory. An exact sum-rule which the momentum-dependent pairing susceptibility satisfies is derived. Effective pairing interactions between quasiparticles are determined so that an approximate susceptibility should fulfill this sum-rule, in which fluctuations belonging to different symmetries mix at finite momentum. The mixing leads to a suppression of the d{sub x{sup 2}-y{sup 2}} pairing close to the half-filling, resulting in a maximum of T{sub c} away from half-filling.

In the current social climate, breastfeeding is regarded as the "gold standard" of babies' nutrition and optimal mothering. It is not surprising, therefore, that the vast majority of contemporary women begin breastfeeding after they give birth. This paper presents two separate quantitative studies conducted in Israel which examined breastfeeding motivation and its association with maternal well-being as derived from Self-Determination Theory (SDT). In Study I, a new breastfeeding motivation scale reflecting the various SDT-informed motivations was developed. Study II sought to validate the structure of the scale and to examine the hypotheses derived from SDT. In Study I, which took place in 2007, 130 mothers of at least one child under the age of eight years old filled out the Breastfeeding Motivation Scale. In Study II, which took place during the years 2008-2010, a different sample of 236 women were followed at three different time points: during the third trimester of pregnancy, at eight weeks postnatal, and at five months postnatal. The participants completed the Breastfeeding Motivation Scale and maternal well-being, maternal self-efficacy and maternal attachment questionnaires. The findings supported the structure of the Breastfeeding Motivation Scale according to SDT. As predicted, autonomous motivation was positively correlated with maternal well-being and self-efficacy, while controlled motivations were positively associated with distress and inversely correlated with self-efficacy. Anxious attachment predicted both controlled and autonomous breastfeeding motivations. The findings support the validity of the SDT for breastfeeding motivations, and highlight the role of these motivations as differentiating between positive and negative subjective well-being, among breastfeeding women.

Saperstein, E. E.; Tolokonnikov, S. V.

2011-01-01

Present-day self-consistent approaches in nuclear theory were analyzed from the point of view of describing distributions of nuclear densities. The generalized method of the energy density functional due to Fayans and his coauthors (this is the most successful version of the self-consistent theory of finite Fermi systems) was the first among the approaches under comparison. The second was the most successful version of the Skyrme-Hartree-Fock method with the HFB-17 functional due to Goriely and his coauthors. Charge radii of spherical nuclei were analyzed in detail. Several isotopic chains of deformed nuclei were also considered. Charge-density distributions ρ ch (r) were calculated for several spherical nuclei. They were compared with model-independent data extracted from an analysis of elastic electron scattering on nuclei.
Family planning and married fulfillment.

Science.gov (United States)

Burke, C

1989-01-01

Large numbers of children typified the Catholic family until the 60s when there was a general societal change towards smaller families. This change, which even affected Catholics, is thought to derive from 3 sources. The population explosion and its complimentary disadvantages, a change towards more egocentric values, and an increase in the importance of material values. The Western world is aging fast and fertility rates are falling to the point that an overall effect of population reduction is occurring. Children have become only an optional, instead of necessary as in previous generations, part of most couples' lifestyles in West. Careers, social status, gadgets, vacations, ease, and comfort are now commonly seen as more self- fulfilling than children. The Catholic church believes that the only reasons for family planning are natural methods used out of necessity. Vatican II clearly states that the purpose of marriage is the raising of children. It has become the opinion of many that marriage and children are only accidentally connected and that the 2 are not bound inseparably. It is the authors contention that this dualistic view of marriage and children is false. The author feels that through a marriage people can draw each other out of themselves and towards their children. Sacrificing oneself for one's children is the natural end to marriage. The author admits that family planning has been a great good to the world for the couples that need it to survive, but that couples that can have children should do so.

2005-01-01

Within the constrained Hartree-Fock (CHF) theory, an analytic condition is derived to estimate whether a concept of the self-consistent mean field is realized in the level repulsive region. The derived condition states that an iterative calculation of the CHF equation does not converge when the quantum fluctuations coming from two-body residual interaction and quadrupole deformation become larger than a single-particle energy difference between two avoided crossing orbits. By means of numerical calculation, it is shown that the analytic condition works well for a realistic case
A synthesis theory for self-oscillating adaptive systems /SOAS/

Science.gov (United States)

Horowitz, I.; Smay, J.; Shapiro, A.

1974-01-01

A quantitative synthesis theory is presented for the Self-Oscillating Adaptive System (SOAS), whose nonlinear element has a static, odd character with hard saturation. The synthesis theory is based upon the quasilinear properties of the SOAS to forced inputs, which permits the extension of quantitative linear feedback theory to the SOAS. A reasonable definition of optimum design is shown to be the minimization of the limit cycle frequency. The great advantages of the SOAS is its zero sensitivity to pure gain changes. However, quasilinearity and control of the limit cycle amplitude at the system output, impose additional constraints which partially or completely cancel this advantage, depending on the numerical values of the design parameters. By means of narrow-band filtering, an additional factor is introduced which permits trade-off between filter complexity and limit cycle frequency minimization.
Low adolescent self-esteem leads to multiple interpersonal problems: a test a social-adaptation theory.

Science.gov (United States)

Kahle, L R; Kulka, R A; Klingel, D M

1980-09-01

This article reports the results of a study that annually monitored the self-esteem and interpersonal problems of over 100 boys during their sophomore, junior, and senior years of high school. Cross-lagged panel correlation differences show that low self-esteem leads to interpersonal problems in all three time lags when multiple interpersonal problems constitute the dependent variable but not when single interpersonal problem criteria constitute the dependent variable. These results are interpreted as supporting social-adaptation theory rather than self-perception theory. Implications for the conceptual status of personality variables as causal antecedents and for the assessment of individual differences are discussed.

Among numerous motivational theories, goal setting theory particularly can serve strategic human resource development practices. The goal-setting theory suggests that organizational goals have to be communicated clearly and the goals need to be specific enough. Another feature of goal-setting is that they need not be too easy or perceived to be impossible to fulfill. SHRD personnel should keep in mind that some employees prefer to work individually toward fulfilling a goal, while others prefe...
The Effects of Theory of Mind and Self-Regulation Skills on Helping Behaviors in 3-4-Year-Old Children

Full Text Available The aim of this study is to examine the effects of theory of mind and self-regulation skills on children’s helping behavior. Total of 104 children aging between 36-59 months, participated in the study. Helping behavior was measured with an instrumental helping task. Scaling of Theory-of-Mind tasks were used in measuring theory of mind. As for measuring self-regulation, peg tapping task were used. In order to control receptive language abilities of children, Turkish Expressive and Receptive Language Test (TIFALDI was applied. Results of the analyses indicated that there were significant relations between theory of mind and selfregulation skills and helping behavior, however, multiple regression analyses showed that the main predictor of helping behavior was theory of mind, but not self-regulation skills after controlling for age and receptive language. Results were discussed with respect to the literature, in relation to the role of theory of mind and self-regulation skills in explaining helping behavior.

One of the enduring missions of personality science is to unravel what it takes to become a fully functioning person. In the present article, the authors address this matter from the perspectives of self-determination theory (SDT) and personality systems interactions (PSI) theory. SDT (a) is rooted in humanistic psychology; (b) has emphasized a first-person perspective on motivation and personality; (c) posits that the person, supported by the social environment, naturally moves toward growth through the satisfaction of basic psychological needs for autonomy, competence, and relatedness. PSI theory (a) is rooted in German volition psychology; (b) has emphasized a third-person perspective on motivation and personality; and (c) posits that a fully functioning person can form and enact difficult intentions and integrate new experiences, and that such competencies are facilitated by affect regulation. The authors review empirical support for SDT and PSI theory, their convergences and divergences, and how the theories bear on recent empirical research on internalization, vitality, and achievement flow. The authors conclude that SDT and PSI theory offer complementary insights into developing a person's full potential. © 2018 The Authors. Journal of Personality Published by Wiley Periodicals, Inc.

Doubly self-consistent field theory of grafted polymers under simple shear in steady state

International Nuclear Information System (INIS)

Suo, Tongchuan; Whitmore, Mark D.

2014-01-01

We present a generalization of the numerical self-consistent mean-field theory of polymers to the case of grafted polymers under simple shear. The general theoretical framework is presented, and then applied to three different chain models: rods, Gaussian chains, and finitely extensible nonlinear elastic (FENE) chains. The approach is self-consistent at two levels. First, for any flow field, the polymer density profile and effective potential are calculated self-consistently in a manner similar to the usual self-consistent field theory of polymers, except that the calculation is inherently two-dimensional even for a laterally homogeneous system. Second, through the use of a modified Brinkman equation, the flow field and the polymer profile are made self-consistent with respect to each other. For all chain models, we find that reasonable levels of shear cause the chains to tilt, but it has very little effect on the overall thickness of the polymer layer, causing a small decrease for rods, and an increase of no more than a few percent for the Gaussian and FENE chains. Using the FENE model, we also probe the individual bond lengths, bond correlations, and bond angles along the chains, the effects of the shear on them, and the solvent and bonded stress profiles. We find that the approximations needed within the theory for the Brinkman equation affect the bonded stress, but none of the other quantities
Three-dimensional loop quantum gravity: towards a self-gravitating quantum field theory

International Nuclear Information System (INIS)

Noui, Karim

2007-01-01

In a companion paper, we have emphasized the role of the Drinfeld double DSU(2) in the context of three-dimensional Riemannian loop quantum gravity coupled to massive spinless point particles. We make use of this result to propose a model for a self-gravitating quantum field theory (massive spinless non-causal scalar field) in three-dimensional Riemannian space. We start by constructing the Fock space of the free self-gravitating field: the vacuum is the unique DSU(2) invariant state, one-particle states correspond to DSU(2) unitary irreducible simple representations and any multi-particles states are obtained as the symmetrized tensor product between simple representations. The associated quantum field is defined by the usual requirement of covariance under DSU(2). Then, we introduce a DSU(2)-invariant self-interacting potential (the obtained model is a group field theory) and explicitly compute the lowest order terms (in the self-interaction coupling constant λ) of the propagator and of the three-point function. Finally, we compute the lowest order quantum gravity corrections (in the Newton constant G) to the propagator and to the three-point function
Multicultural adolescents between tradition and postmodernity: Dialogical Self Theory and the paradox of localization and globalization.

2012-01-01

This chapter builds on Dialogical Self Theory to investigate the identity development of adolescents growing up in multicultural societies. Their cultural identity is not only compounded by the rapid cultural changes associated with globalization, but also by the paradoxical revival of cultural traditions which the large-scale compression of time and space has incited at local levels of society. Dialogical Self Theory, which is based on the metaphor of the self as a "society of mind," helps to understand the dilemmas of tradition and postmodernity, of localization and globalization, within the self of individual youngsters.

Modeling self on others: An import theory of subjectivity and selfhood.

Science.gov (United States)

Prinz, Wolfgang

2017-03-01

This paper outlines an Import Theory of subjectivity and selfhood. Import theory claims that subjectivity is initially perceived as a key feature of other minds before it then becomes imported from other minds to own minds whereby it lays the ground for mental selfhood. Import theory builds on perception-production matching, which in turn draws on both representational mechanisms and social practices. Representational mechanisms rely on common coding of perception and production. Social practices rely on action mirroring in dyadic interactions. The interplay between mechanisms and practices gives rise to model self on others. Individuals become intentional agents in virtue of perceiving others mirroring themselves. The outline of the theory is preceded by an introductory section that locates import theory in the broader context of competing approaches, and it is followed by a concluding section that assesses import theory in terms of empirical evidence and explanatory power.

Voice Use Among Music Theory Teachers: A Voice Dosimetry and Self-Assessment Study.

Schiller, Isabel S; Morsomme, Dominique; Remacle, Angélique

2017-07-25

This study aimed (1) to investigate music theory teachers' professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data. Using voice dosimetry, 13 music theory teachers were monitored for one workweek. The parameters analyzed were voice sound pressure level (SPL), fundamental frequency (F0), phonation time, vocal loading index (VLI), and noise SPL. Spearman correlation was used to correlate vocal loading parameters (voice SPL, F0, and phonation time) and noise SPL. Each day, the subjects self-assessed their voice using visual analog scales. VLI and self-evaluation data were correlated using Spearman correlation. Vocal loading parameters and noise SPL were significantly higher in the professional than in the extra-professional environment. Voice SPL, phonation time, and female subjects' F0 correlated positively with noise SPL. VLI correlated with self-assessed voice quality, vocal fatigue, and amount of singing and speaking voice produced. Teaching music theory is a profession with high vocal demands. More background noise is associated with increased vocal loading and may indirectly increase the risk for voice disorders. Correlations between VLI and self-assessments suggest that these teachers are well aware of their vocal demands and feel their effect on voice quality and vocal fatigue. Visual analog scales seem to represent a useful tool for subjective vocal loading assessment and associated symptoms in these professional voice users. Copyright © 2017 The Voice Foundation.

Thermodynamically self-consistent theory for the Blume-Capel model.

Science.gov (United States)

Grollau, S; Kierlik, E; Rosinberg, M L; Tarjus, G

2001-04-01

We use a self-consistent Ornstein-Zernike approximation to study the Blume-Capel ferromagnet on three-dimensional lattices. The correlation functions and the thermodynamics are obtained from the solution of two coupled partial differential equations. The theory provides a comprehensive and accurate description of the phase diagram in all regions, including the wing boundaries in a nonzero magnetic field. In particular, the coordinates of the tricritical point are in very good agreement with the best estimates from simulation or series expansion. Numerical and analytical analysis strongly suggest that the theory predicts a universal Ising-like critical behavior along the lambda line and the wing critical lines, and a tricritical behavior governed by mean-field exponents.
Exhaustion Experiences in Junior Athletes: The Importance of Motivation and Self-Control Competencies.

Jordalen, Gro; Lemyre, Pierre-Nicolas; Durand-Bush, Natalie

2016-01-01

Quality of motivation, self-control competencies, as well as past performance experience influence sport participation outcomes in developing athletes. Studies have shown that junior athletes high in self-determined motivation are less prone to experience burnout, while self-control competencies help developing athletes to be conscious and deliberate in their self-regulatory efforts toward elite sport performances and avoid negative sport participation outcomes. Combining the self-determination theory framework and psychosocial theories of self-regulation, the aim of this cross-sectional study was to examine how various types of motivation and self-control competencies together are associated with the development of burnout symptoms in junior athletes. High-level Norwegian winter-sport athletes from elite sport academies ( N = 199; female n = 72; 16-20 years of age) consented to participate. Associations between six types of motivational regulation, self-control, and indices of exhaustion were investigated. We hypothesized that athletes' self-control competencies are important to operate successfully, and influenced by different types of motivation, they are expected to help athletes avoid negative sport participation outcomes such as emotional and physical exhaustion. Structural equation modeling analyses were conducted to analyze these relationships, and results revealed some multifaceted associations. When identifying antecedents of sport participation exhaustion and burnout, there is a need to go beyond the unique framework of motivation theories, and explore what cognitive competencies ensure fulfillment of motivation desires. In the current study, differences in junior athletes' quality of motivation influenced self-control competencies when predicting exhaustion. Interestingly, young athletes driven by self-determined (intrinsic, integrated, and identified), and controlled (introjected and amotivation) regulations in association with self-control offered the

Testing a self-determination theory model of children's physical activity motivation: a cross-sectional study.

2013-09-26

Understanding children's physical activity motivation, its antecedents and associations with behavior is important and can be advanced by using self-determination theory. However, research among youth is largely restricted to adolescents and studies of motivation within certain contexts (e.g., physical education). There are no measures of self-determination theory constructs (physical activity motivation or psychological need satisfaction) for use among children and no previous studies have tested a self-determination theory-based model of children's physical activity motivation. The purpose of this study was to test the reliability and validity of scores derived from scales adapted to measure self-determination theory constructs among children and test a motivational model predicting accelerometer-derived physical activity. Cross-sectional data from 462 children aged 7 to 11 years from 20 primary schools in Bristol, UK were analysed. Confirmatory factor analysis was used to examine the construct validity of adapted behavioral regulation and psychological need satisfaction scales. Structural equation modelling was used to test cross-sectional associations between psychological need satisfaction, motivation types and physical activity assessed by accelerometer. The construct validity and reliability of the motivation and psychological need satisfaction measures were supported. Structural equation modelling provided evidence for a motivational model in which psychological need satisfaction was positively associated with intrinsic and identified motivation types and intrinsic motivation was positively associated with children's minutes in moderate-to-vigorous physical activity. The study provides evidence for the psychometric properties of measures of motivation aligned with self-determination theory among children. Children's motivation that is based on enjoyment and inherent satisfaction of physical activity is associated with their objectively-assessed physical
The role of individualist and collectivist orientations on self-determined motivation: integrating self-determination theory and group processes

OpenAIRE

Rentzelas, Panagiotis

2009-01-01

The main aim of this thesis was to examine the role of individualism and collectivism as situational group norms on intrinsic motivation. A further aim was to examine the effect of individual differences in individualist and collectivist orientations on the effect of autonomous motivation on intention and behaviour. This research integrated the concept of self-determined and intrinsic motivation as postulated in Self-Determination Theory (Deci & Ryan, 1985a, 2000,2002), individualism and coll...
Mean-field theory and self-consistent dynamo modeling

International Nuclear Information System (INIS)

Yoshizawa, Akira; Yokoi, Nobumitsu

2001-12-01

Mean-field theory of dynamo is discussed with emphasis on the statistical formulation of turbulence effects on the magnetohydrodynamic equations and the construction of a self-consistent dynamo model. The dynamo mechanism is sought in the combination of the turbulent residual-helicity and cross-helicity effects. On the basis of this mechanism, discussions are made on the generation of planetary magnetic fields such as geomagnetic field and sunspots and on the occurrence of flow by magnetic fields in planetary and fusion phenomena.

General variational many-body theory with complete self-consistency for trapped bosonic systems

International Nuclear Information System (INIS)

Streltsov, Alexej I.; Alon, Ofir E.; Cederbaum, Lorenz S.

2006-01-01

In this work we develop a complete variational many-body theory for a system of N trapped bosons interacting via a general two-body potential. The many-body solution of this system is expanded over orthogonal many-body basis functions (configurations). In this theory both the many-body basis functions and the respective expansion coefficients are treated as variational parameters. The optimal variational parameters are obtained self-consistently by solving a coupled system of noneigenvalue--generally integro-differential--equations to get the one-particle functions and by diagonalizing the secular matrix problem to find the expansion coefficients. We call this theory multiconfigurational Hartree theory for bosons or MCHB(M), where M specifies explicitly the number of one-particle functions used to construct the configurations. General rules for evaluating the matrix elements of one- and two-particle operators are derived and applied to construct the secular Hamiltonian matrix. We discuss properties of the derived equations. We show that in the limiting cases of one configuration the theory boils down to the well-known Gross-Pitaevskii and the recently developed multi-orbital mean fields. The invariance of the complete solution with respect to unitary transformations of the one-particle functions is utilized to find the solution with the minimal number of contributing configurations. In the second part of our work we implement and apply the developed theory. It is demonstrated that for any practical computation where the configurational space is restricted, the description of trapped bosonic systems strongly depends on the choice of the many-body basis set used, i.e., self-consistency is of great relevance. As illustrative examples we consider bosonic systems trapped in one- and two-dimensional symmetric and asymmetric double well potentials. We demonstrate that self-consistency has great impact on the predicted physical properties of the ground and excited states
Fulfilment of administrative and professional organisational obligations and nurses' customer-oriented behaviours.

Trybou, Jeroen; Gemmel, Paul

2016-07-01

The aim of the study was to examine the relationship between the perceived quality of organisational exchange and nurses' customer-oriented behaviours. Hospitals face increasing competitive market conditions. Registered nurses interact closely with patients and therefore play an important front-office role towards patients. A cross-sectional study was conducted. Registered nurses (n = 151) of a Belgian hospital received a questionnaire to assess the fulfilment of administrative and professional organisational obligations and their customer-oriented behaviours. We found a positive relationship between psychological contract fulfilment and nurses' customer-oriented behaviours. More precisely administrative and professional psychological contract fulfilment relates significantly to nurses' service delivery and external representation. In case of internal influence only administrative psychological contract fulfilment was significantly related. Nurses' perceptions of the fulfilment of administrative and professional obligations are important to their customer-oriented behaviours. Nurse managers must be aware of the impact of fulfilling both administrative and professional obligations of registered nurses in order to optimise their customer-oriented behaviours. © 2016 John Wiley & Sons Ltd.
Terror management theory and self-esteem revisited: the roles of implicit and explicit self-esteem in mortality salience effects.

Three studies tested the roles of implicit and/or explicit self-esteem in reactions to mortality salience. In Study 1, writing about death versus a control topic increased worldview defense among participants low in implicit self-esteem but not among those high in implicit self-esteem. In Study 2, a manipulation to boost implicit self-esteem reduced the effect of mortality salience on worldview defense. In Study 3, mortality salience increased the endorsement of positive personality descriptions but only among participants with the combination of low implicit and high explicit self-esteem. These findings indicate that high implicit self-esteem confers resilience against the psychological threat of death, and therefore the findings provide direct support for a fundamental tenet of terror management theory regarding the anxiety-buffering role of self-esteem.

Competing discourses of the “Maya Past”

Directory of Open Access Journals (Sweden)

Denise Fay Brown

2010-12-01

Full Text Available The use of the "Maya past" for tourism marketing purposes has been a successful tool for attracting international visitors to Mexico for decades. Images of the Maya zone emerge, in part, from an academic focus on the "Maya past" that includes curiosity about the so-called "collapse" of the Classic Maya civilization. The Ancient Maya are seen as “mysterious" and their society as "enigmatic". But the voices of the almost thirty million Maya people who live in Mexico and Guatemala are only vaguely heard in the discourses of tourism and of academia. This paper examines three competing discourses of the Maya and proposes that these discourses represent epistemologies that are nested in relationships of power, such that the Maya discourse is silenced. As such, the dominant discourses of the Maya past can undermine the Maya understanding of their own past, and become a self-fulfilling prophecy regarding the “collapse” of the contemporary Maya.

It is clarified that the so-caned 'helicity conservation law' is never the conservation equation of the helicity K itself', but is merely 'the time change rate equation of K', which is passively and resultantly determined by the mutually independent volume and surface integral terms. It is shown that since the total helicity K can never be conserved in the real experimental systems, the conjecture of the total helicity invariance is not physically available to real magnetized plasmas in an exact sense. The well-known relaxation theory by Dr. J. B. Taylor is clarified to be neither the variational principle nor the energy principle, but be merely a mathematical calculation, using the variational calculus in order to find the minimum magnetic energy solution from the set of solutions having the same value of K. With the use of auto-correlations for physical quantities, it is presented that a novel basic formulation of an extended generalized self-organization theory, which is not based on neither the variational principle nor the energy principle. It is clarified that conservation equations concerning with all physical quantities for the dynamic system of interest are naturally embedded in the formulation of the generalized self-organization theory. The self-organized states of every physical quantities of interest may be realized during their own phases and the dynamical system may evolve repeatedly those out of phase organizations, depending on boundary conditions and input powers. It is shown that the conservation laws can be used to extend conventional methods of plasma current drives by energy injections with use of various types of energies, such as magnetic energies, electromagnetic wave energies, internal energies of plasmoids by plasma guns, which induce the thermal plasma flow velocity, various particle beam energies, and so on.

A Capabilities Analysis of E-Fulfilment Businesses: transformation in the logistics industry

Directory of Open Access Journals (Sweden)

Janice Burn

2005-11-01

Full Text Available This paper reports on the evaluation of practices of 48 leading e-fulfillment suppliers in the UK. Initial findings suggest that while a comprehensive model of e-fulfilment is validated these organisations are also providing services not previously recognised as e-fulfilment capabilities by the literature. This leads to the development of a staged model of transformation, which implies that the industry will embrace radical change in some sectors and lead to a new definition of e-fulfillment businesses. More in depth investigation leads to a proposed definition, and a methodology to measure the degree of transformation.
Perceived teaching behaviors and self-determined motivation in physical education: a test of self-determination theory.

Koka, Andre; Hagger, Martin S

2010-03-01

In the present study, we tested the effects of specific dimensions of perceived teaching behaviors on students' self-determined motivation in physical education. In accordance with the tenets of self-determination theory (Deci & Ryan, 1985, 2000), we expected the psychological needs for competence, autonomy, and relatedness would mediate these effects. Secondary school students (N=498) ages 12-17 years completed measures of perceived teaching behaviors for seven dimensions: (a) democratic behavior, (b) autocratic behavior (c) teaching and instruction, (d) situation consideration, (e) positive general feedback, (f) positive nonverbal feedback, and (h) negative nonverbal feedback. They also completed measures of perceived satisfaction for competence, autonomy, relatedness, and self-determined motivation. A path-analytic model revealed a positive, indirect effect of perceived positive general feedback on self-determined motivation. The effects of perceived autocratic behavior and negative nonverbal feedback were direct and negative, whereas the effects of teaching and instruction and situation consideration were direct and positive. Results suggest that feedback, situation consideration, and teaching and instruction are essential antecedents to self-determined motivation.

Full Text Available This study aimed to identify the conditioning factors to self-care practice of ostomy patients, and verify knowledge and practices on stoma care. Descriptive and qualitative study, referencing the Orem’s Self-Care Theory, carried out at the Ostomy Association of Fortaleza-CE, Brazil, in June and July 2007. We identified as the main conditioning factors for self-care: male, aged over 51 years, low education, from the capital city/metropolitan area, married, and with low family income. From the participants’ statements, emerged three categories: Learning to take care of stoma: education-support system; Stoma Care: knowledge and practices; and Difficulties found in the practice of self-care. It was concluded that ostomy patients require a multidimensional and individualized nursing care, which enables them to perform self-care effectively.
Parents' role in early adolescent self-injury: An application of self-determination theory.

Emery, A Ann; Heath, Nancy L; Rogers, Maria

2017-06-01

We applied self-determination theory to examine a model whereby perceived parental autonomy support directly and indirectly affects nonsuicidal self-injury (NSSI) through difficulties in emotion regulation. 639 participants (53% female) with a mean age of 13.38 years (SD = 0.51) completed the How I Deal with Stress Questionnaire as a screener for NSSI, the Perceptions of Parents Scale, and the Difficulties in emotion Regulation Scale. Participants who indicated having ever hurt themselves on purpose without the intent to die (n = 116, 66% female) were classified in the NSSI lifetime group. A mediation analysis with bootstrapping procedure revealed that adolescents who reported their parents as being less supportive of their need for autonomy were more likely to have engaged in NSSI. Further, this relationship was partially mediated by emotion regulation. Adolescents who do not perceive autonomy support from their parents, have more difficulties regulating their emotions, and may turn to NSSI as a means to cope. Clinical implications of the findings suggest involving the family, and specifically, targeting parental autonomy support may be beneficial when working with young adolescents who self-injure.

A self-consistent nonlinear theory of resistive-wall instability in a relativistic electron beam

International Nuclear Information System (INIS)

Uhm, H.S.

1994-01-01

A self-consistent nonlinear theory of resistive-wall instability is developed for a relativistic electron beam propagating through a grounded cylindrical resistive tube. The theory is based on the assumption that the frequency of the resistive-wall instability is lower than the cutoff frequency of the waveguide. The theory is concentrated on study of the beam current modulation directly related to the resistive-wall klystron, in which a relativistic electron beam is modulated at the first cavity and propagates downstream through the resistive wall. Because of the self-excitation of the space charge waves by the resistive-wall instability, a highly nonlinear current modulation of the electron beam is accomplished as the beam propagates downstream. A partial integrodifferential equation is obtained in terms of the initial energy modulation (ε), the self-field effects (h), and the resistive-wall effects (κ). Analytically investigating the partial integrodifferential equation, a scaling law of the propagation distance z m at which the maximum current modulation occurs is obtained. It is found in general that the self-field effects dominate over the resistive-wall effects at the beginning of the propagation. As the beam propagates farther downstream, the resistive-wall effects dominate. Because of a relatively large growth rate of the instability, the required tube length of the klystron is short for most applications

The issue of interactional hypothesis in self-determination theory: a proposal of a new motivation quality index

Directory of Open Access Journals (Sweden)

José Martín-Albo

2014-01-01

Full Text Available The postulates of self-determination theory have been frequently gauged by a measure of motivation quality called self-determination index (SDI. This index relies on an interactional hypothesis. According to this hypothesis, intrinsic motivation and extrinsic motivation are not independent constructs; on the contrary, when one increases the other decreases. However, the literature on the subiect has revealed that these constructs are orthogonal and thus SDI presents measurement problems. Considering these limitations, the obiective of this research was to propose and test the effectiveness of a new way to calculate a motivation quality index (PMI: positive motivation index. Two athletes' samples were used. Results of the two studies carried out showed that PMI fit better the self-determination theory postulates than SDI did. Positive correlations were found between the satisfaction of basic psychological needs and PMI, and between PMI and positive emotions. Finally, results provided preliminary support for the use of the new motivation quality index proposed from the framework of self-determination theory.
Personalised Learning Object System Based on Self-Regulated Learning Theories

Full Text Available Self-regulated learning has become an important construct in education research in the last few years. Selfregulated learning in its simple form is the learner’s ability to monitor and control the learning process. There is increasing research in the literature on how to support students become more self-regulated learners. However, the advancement in the information technology has led to paradigm changes in the design and development of educational content. The concept of learning object instructional technology has emerged as a result of this shift in educational technology paradigms. This paper presents the results of a study that investigated the potential educational effectiveness of a pedagogical framework based on the self-regulated learning theories to support the design of learning object systems to help computer science students. A prototype learning object system was developed based on the contemporary research on self-regulated learning. The system was educationally evaluated in a quasi-experimental study over two semesters in a core programming languages concepts course. The evaluation revealed that a learning object system that takes into consideration contemporary research on self-regulated learning can be an effective learning environment to support computer science education.
Self psychology as a shift away from the paranoid strain in classical analytic theory.

Science.gov (United States)

Terman, David M

2014-12-01

Classical psychoanalytic theory has a paranoid strain. There is, in effect, an "evil other"--the id--within each individual that must be tamed in development and confronted and worked through as resistance in treatment. This last has historically endgendered an adversarial relationship between patient and analyst. This paranoid strain came from a paranoid element in Freud's personality that affected his worldview, his relationships, and his theory. Self psychology offers a different view of development and conflict. It stresses the child's need for responsiveness from and admiration of caretakers in order to develop a well-functioning self. Though severe behavioral and character problems may result from faults in the process of self-construction, the essential need is not instinctual discharge but connection. Hence the long-assumed opposition between individual needs and social institutions or between patient and analyst is no longer inevitable or universal. Rather, an understanding of the primary need for connection creates both a different interpretive stance and a more cooperative ambience. These changes in theory and technique are traced to Kohut's personal struggles to emancipate himself from his paranoid mother. © 2014 by the American Psychoanalytic Association.
Testing self-determined motivation as a mediator of the relationship between psychological needs and affective and behavioral outcomes.

Science.gov (United States)

McDonough, Meghan H; Crocker, Peter R E

2007-10-01

Self-determination theory suggests that when psychological needs for autonomy, competence, and relatedness are met, participants experience more self-determined types of motivation and more positive outcomes. Limited research has examined this mediational role of self-determined motivation in adult physical activity participants, and very few studies have included assessments of relatedness. This study tested the hypothesis that self-determined motivation would mediate the relationship between psychological need fulfillment and affective and behavioral outcomes. Adult dragon boaters (N = 558) between the ages of 19 and 83 completed a questionnaire on motivational aspects of dragon boating. Competence, relatedness, and autonomy all significantly predicted self-determined motivation, but self-determined motivation only partially mediated their relationship with positive and negative affect. These findings demonstrate the importance of all three needs in adult activity motivation and suggest that the relationships between needs, self-determination, and outcomes may be complex.
Connection between Einstein equations, nonlinear sigma models, and self-dual Yang-Mills theory

Sanchez, N.; Whiting, B.

1986-01-01

The authors analyze the connection between nonlinear sigma models self-dual Yang-Mills theory, and general relativity (self-dual and non-self-dual, with and without killing vectors), both at the level of the equations and at the level of the different type of solutions (solitons and calorons) of these theories. They give a manifestly gauge invariant formulation of the self-dual gravitational field analogous to that given by Yang for the self-dual Yang-Mills field. This formulation connects in a direct and explicit way the self-dual Yang-Mills and the general relativity equations. They give the ''R gauge'' parametrization of the self-dual gravitational field (which corresponds to modified Yang's-type and Ernst equations) and analyze the correspondence between their different types of solutions. No assumption about the existence of symmetries in the space-time is needed. For the general case (non-self-dual), they show that the Einstein equations contain an O nonlinear sigma model. This connection with the sigma model holds irrespective of the presence of symmetries in the space-time. They found a new class of solutions of Einstein equations depending on holomorphic and antiholomorphic functions and we relate some subclasses of these solutions to solutions of simpler nonlinear field equations that are well known in other branches of physics, like sigma models, SineGordon, and Liouville equations. They include gravitational plane wave solutions. They analyze the response of different accelerated quantum detector models, compare them to the case when the detectors are linterial in an ordinary Planckian gas at a given temperature, and discuss the anisotropy of the detected response for Rindler observers
Testing a self-determination theory model of children’s physical activity motivation: a cross-sectional study

Science.gov (United States)

2013-01-01

Background Understanding children’s physical activity motivation, its antecedents and associations with behavior is important and can be advanced by using self-determination theory. However, research among youth is largely restricted to adolescents and studies of motivation within certain contexts (e.g., physical education). There are no measures of self-determination theory constructs (physical activity motivation or psychological need satisfaction) for use among children and no previous studies have tested a self-determination theory-based model of children’s physical activity motivation. The purpose of this study was to test the reliability and validity of scores derived from scales adapted to measure self-determination theory constructs among children and test a motivational model predicting accelerometer-derived physical activity. Methods Cross-sectional data from 462 children aged 7 to 11 years from 20 primary schools in Bristol, UK were analysed. Confirmatory factor analysis was used to examine the construct validity of adapted behavioral regulation and psychological need satisfaction scales. Structural equation modelling was used to test cross-sectional associations between psychological need satisfaction, motivation types and physical activity assessed by accelerometer. Results The construct validity and reliability of the motivation and psychological need satisfaction measures were supported. Structural equation modelling provided evidence for a motivational model in which psychological need satisfaction was positively associated with intrinsic and identified motivation types and intrinsic motivation was positively associated with children’s minutes in moderate-to-vigorous physical activity. Conclusions The study provides evidence for the psychometric properties of measures of motivation aligned with self-determination theory among children. Children’s motivation that is based on enjoyment and inherent satisfaction of physical activity is
Constructive processes in person cognition.

Science.gov (United States)

Fiedler, K

1993-12-01

The notion of constructive memory processes is imported from research on eyewitness memory to the area of social cognition. Mere questioning about the applicability of personality attributes to a target person is shown to affect subsequent memory-based judgements of that person. These constructive influences are to be distinguished, conceptually, from the global notion of priming effects. In Expt 1, the target person was first described as an extravert; afterwards, subjects had to indicate whether either desirable aspects of extraversion (self-confidence) or undesirable aspects (exhibitionism) apply to the target or not. Mere questioning resulted in a congruent judgment bias towards the questioned attributes that did not generalize to a global halo effect. Experiment 2 replicated the basic finding and demonstrated that this phenomenon is independent of a generation effect (i.e. the memory advantage of self-generated inferences). These results are interpreted in terms of (a) a reframing of the categorical distribution representing the information about the target person in memory and (b) a regressive tendency to assume intermediate default values rather than extreme values for questioned attributes under uncertainty. Alternative explanations in terms of demand effects or a conformation bias cannot provide sufficient accounts. The relevance of constructive processes to understanding self-fulfilling prophecies and other phenomena in social interaction is discussed.

Kinematic matrix theory and universalities in self-propellers and active swimmers.

We describe an efficient and parsimonious matrix-based theory for studying the ensemble behavior of self-propellers and active swimmers, such as nanomotors or motile bacteria, that are typically studied by differential-equation-based Langevin or Fokker-Planck formalisms. The kinematic effects for elementary processes of motion are incorporated into a matrix, called the "kinematrix," from which we immediately obtain correlators and the mean and variance of angular and position variables (and thus effective diffusivity) by simple matrix algebra. The kinematrix formalism enables us recast the behaviors of a diverse range of self-propellers into a unified form, revealing universalities in their ensemble behavior in terms of new emergent time scales. Active fluctuations and hydrodynamic interactions can be expressed as an additive composition of separate self-propellers.
Parenting, self-control, and delinquency: examining the applicability of Gottfredson and Hirschi's general theory of crime to South Korean youth.

Science.gov (United States)

Jo, Youngoh; Zhang, Yan

2014-11-01

Limited studies have examined whether self-control fully mediates the effect of parenting on deviant behavior beyond Western cultures. Using a sample of 882 South Korean middle and high schools students, this article examines the applicability of Gottfredson and Hirschi's argument about the role of parenting in self-control theory in the context of Asian culture. Results of structural equation modeling (SEM) suggest the relationships among parenting, self-control, and delinquency hold in South Korean culture: Parenting has only an indirect effect through self-control on delinquency. The findings of multigroup SEM, however, indicate that gender differences exist in the relationships among parenting, self-control, and delinquency. This study provides support for cultural invariance of self-control theory but suggests that more studies examining gender differences and interaction between gender and race in the theory are required. © The Author(s) 2013.
Self-Interaction Error in Density Functional Theory: An Appraisal.

Science.gov (United States)

Bao, Junwei Lucas; Gagliardi, Laura; Truhlar, Donald G

2018-05-03

Self-interaction error (SIE) is considered to be one of the major sources of error in most approximate exchange-correlation functionals for Kohn-Sham density-functional theory (KS-DFT), and it is large with all local exchange-correlation functionals and with some hybrid functionals. In this work, we consider systems conventionally considered to be dominated by SIE. For these systems, we demonstrate that by using multiconfiguration pair-density functional theory (MC-PDFT), the error of a translated local density-functional approximation is significantly reduced (by a factor of 3) when using an MCSCF density and on-top density, as compared to using KS-DFT with the parent functional; the error in MC-PDFT with local on-top functionals is even lower than the error in some popular KS-DFT hybrid functionals. Density-functional theory, either in MC-PDFT form with local on-top functionals or in KS-DFT form with some functionals having 50% or more nonlocal exchange, has smaller errors for SIE-prone systems than does CASSCF, which has no SIE.

Health-promoting self-care behavior emphasizing positive lifestyle practices may improve the health and quality of life of adults. One variable that may influence health-related decisions is the status of basic needs as described by Maslow. The purpose of this study was to investigate the relationships among basic need satisfaction, health-promoting self-care behavior, and selected demographic variables in a sample of community-dwelling adults. A convenience sample of 84 community-dwelling adults was recruited to complete the Basic Need Satisfaction Inventory, the Health-Promoting Lifestyle Profile II, and demographic information. Results of the study indicated that self-actualization, physical, and love/belonging need satisfaction accounted for 64% of the variance in health-promoting self-care behavior. The findings of this study are consistent with Maslow's theory of human motivation and suggest that persons who are more fulfilled and content with themselves and their lives, have physical need satisfaction, and have positive connections with others may be able to make better decisions regarding positive health-promoting self-care behaviors.

A new measure of self-determination, the Self-Determination Inventory: Student Report (Spanish version), has recently been adapted and empirically validated in Spanish language. As it is the first instrument intended to measure self-determination in youth with and without disabilities, there is a need to further explore and strengthen its psychometric analysis based on item response patterns. Through item response theory approach, this study examined item observed distributions across the essential characteristics of self-determination. The results demonstrated satisfactory to excellent item functioning patterns across characteristics, particularly within agentic action domains. Increased variability across items was also found within action-control beliefs dimensions, specifically within the self-realisation subdomain. These findings further support the instrument's psychometric properties and outline future research directions. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

The study investigated the outcomes associated with breach and fulfillment of the psychological contract of safety. The psychological contract of safety is defined as the beliefs of individuals about reciprocal employer and employee safety obligations inferred from implicit or explicit promises. When employees perceive that safety obligations promised by the employer have not been met, a breach of the psychological contract occurs, termed employer breach of obligations. The extent to which employees fulfill their safety obligations to the employer is termed employee fulfillment of obligations. Structural equation modeling was used to test a model of safety that investigated the positive and negative outcomes associated with breach and fulfillment of the psychological contract of safety. Participants were 424 health care workers recruited from two hospitals in the State of Victoria, Australia. Following slight modification of the hypothesized model, a good fitting model resulted. Being injured in the workplace was found to lower perceptions of trust in the employer and increase perceptions of employer breach of safety obligations. Trust in the employer significantly influenced perceived employer breach of safety obligations such that lowered trust resulted in higher perceptions of breach. Perceptions of employer breach significantly impacted employee fulfillment of safety obligations with high perceptions of breach resulting in low employee fulfillment of obligations. Trust and perceptions of breach significantly influenced safety attitudes, but not safety behavior. Fulfillment of employee safety obligations significantly impacted safety behavior, but not safety attitudes. Implications of these findings for safety and psychological contract research are explored. A positive emphasis on social exchange relationships in organizations will have positive outcomes for safety climate and safety behavior. © 2013.

2016-01-01

Full Text Available The purpose of the current paper is to examine the causes of cybercrime victimisation, to highlight limitations of the existing cybercrime victimisation etiological studies and provide guidance for further research. The general findings are reported on the basis of a review of previous empirical studies. In addition to minor deficiencies, elements of self-control and lifestyle/routine activity theory together can be applied to the study of cybercrime victimisation. On the basis of the review of existing research, six main conclusions have been drawn. The limitation of the current research is that examines only the causes of cybercrime victimisation through the application of self-control and lifestyle/routine activity theory as the most useful for this purpose. Future research should take into account all the conclusions discussed in the paper and test new or other existing victimological theories for the purpose of better explaining cybercrime victimisation. This study contributes to improved etiological exploration of cybercrime victimisation and, consequently, to the creation of effective measures to prevent it.

Development of behavior theory-based health promotion programs is encouraged with the paradigm shift from contents to behavior outcomes. This article describes the development process of the diabetes self-management program for older Koreans (DSME-OK) using intervention mapping (IM) protocol. The IM protocol includes needs assessment, defining goals and objectives, identifying theory and determinants, developing a matrix to form change objectives, selecting strategies and methods, structuring the program, and planning for evaluation and pilot testing. The DSME-OK adopted seven behavior objectives developed by the American Association of Diabetes Educators as behavioral outcomes. The program applied an information-motivation-behavioral skills model, and interventions were targeted to 3 determinants to change health behaviors. Specific methods were selected to achieve each objective guided by IM protocol. As the final step, program evaluation was planned including a pilot test. The DSME-OK was structured as the 3 determinants of the IMB model were intervened to achieve behavior objectives in each session. The program has 12 weekly 90-min sessions tailored for older adults. Using the IM protocol in developing a theory-based self-management program was beneficial in terms of providing a systematic guide to developing theory-based and behavior outcome-focused health education programs.

This study examined the demographic and background characteristic differences between those arrested for child pornography (CP) possession (only), or CP production/distribution, or an attempted or completed sexual exploitation of a minor (SEM) that involved the Internet in some capacity within the context of self-control theory using data from the second wave of the National Juvenile Online Victimization Study (N-JOV2). Results indicate few demographic similarities, which thereby suggest these are largely heterogeneous groupings of individuals. Results also indicate CP producers/distributers engaged in a greater number of behaviors indicative of low self-control compared with CP possessors. Specifically, offenders arrested for CP production/distribution were more likely to have (a) had problems with drugs/alcohol at the time of the crime and (b) been previously violent. In contrast, the only indicator of low self-control that reached statistical significance for CP possessors was the previous use of violence. Moreover, in contrast to CP producers/distributers, full-time employment and marital status may be important factors to consider in the likelihood of arrest for CP possessors, which is congruent with the tenets of self-control theory. © The Author(s) 2014.

A self-consistent field theory is developed for polymers that are capable of binding small ionic molecules (adsorbates). The polymer-ionic molecule association is described by Ising-like binding variables, C_(i)^(a)(kΔ)(= 0 or 1), whose average determines the number of adsorbed molecules, nBI. Polymer gelation can occur through polymer-ionic molecule complexation in our model. For polymer-polymer cross-links through the ionic molecules, three types of solutions for nBI are obtained, depending...
Self-Regulation and Mechanisms of Action in Psychotherapy: A Theory-Based Translational Perspective

Strauman, Timothy J.; Goetz, Elena L.; Detloff, Allison M.; MacDuffie, Katherine E.; Zaunmüller, Luisa; Lutz, Wolfgang

2012-01-01

Psychotherapy is a complex, multi-layered process with the potential to bring about changes at multiple levels of functioning, from the neurobiology of the brain to the individual’s role in the social world. Although studies of the mechanisms by which psychotherapy leads to change continue to appear, there remains much to be learned about how psychological interventions work. To guide explorations of how and for whom particular treatment approaches lead to change, researchers can rely on theory to identify potential loci for change and on translational research methods to integrate basic behavioral science and neuroscience with clinical science. In this article, we describe research linking individual differences in the self-regulation of personal goal pursuit with the etiology and treatment of mood disorders. The research draws upon regulatory focus theory as a model of self-regulation and on microintervention designs – controlled laboratory investigations of a specific therapeutic technique – to generate and test hypotheses about how psychological interventions can help to reverse maladaptive self-regulatory processes.

This study aimed to determine the validity and reliability levels of the Planned Behavior Theory Scale as related to a testicular self-examination. The study was carried out in a health-profession higher-education school in Ankara, Turkey, from April to June 2012. The study participants comprised 215 male students. Study data were collected by using a questionnaire, a planned behavior theory scale related to testicular self-examination, and Champion's Health Belief Model Scale (CHBMS). The sub-dimensions of the planned behavior theory scale, namely those of intention, attitude, subjective norms and self-efficacy, were found to have Cronbach's alpha values of between 0.81 and 0.89. Exploratory factor analysis showed that items of the scale had five factors that accounted for 75% of the variance. Of these, the sub-dimension of intention was found to have the highest level of contribution. A significant correlation was found between the sub-dimensions of the testicular self-examination planned behavior theory scale and those of CHBMS (p Planned Behavior Theory Scale is a valid and reliable measurement for Turkish society.

We discuss questions arising from the work of Schellekens [A.N. Schellekens, Phys. Lett. B 277 (1992) 277; Meromorphic c=24 conformal field theories, CERN-TH.6478/92, 1992.] After introducing the concept of complementary representations, we examine Z 2 -orbifold constructions in general, and propose a technique for identifying the orbifold theory without knowledge of its explicit construction. This technique is then generalised to twists of order 3, 5 and 7, and we proceed to apply our considerations to the FKS constructions H (Λ) (Λ an even self-dual lattice) and the reflection-twisted orbifold theories and H ;(Λ), which together remain the only c=24 theories which have so far been proven to exist [L. Dolan, P. Goddard and P. Montague, Nucl. Phys. B 338 (1990) 529.] We also make, in the course of our arguments, some comments on the automorphism groups of the theories H (Λ) and and H ;(Λ), and of meromorphic theories in general, introducing the concept of deterministic theories.

Austin, Stéphanie; Senécal, Caroline; Guay, Frédéric; Nouwen, Arie

2011-09-01

This study tests a model derived from Self-Determination Theory (SDT) (Deci and Ryan, 2000) to explain the mechanisms by which non-modifiable factors influence dietary self-care in adolescents with type 1 diabetes (n = 289). SEM analyses adjusted for HbA1c levels revealed that longer diabetes duration and female gender were indicative of poorer dietary self-care. This effect was mediated by contextual and motivational factors as posited by SDT. Poorer autonomy support from practitioners was predominant in girls with longer diabetes duration. Perceived autonomous motivation and self-efficacy were indicative of greater autonomy support, and led to better dietary self-care.

How children's victimization relates to distorted versus sensitive social cognition: Perception, mood, and need fulfillment in response to Cyberball inclusion and exclusion.

Science.gov (United States)

Lansu, Tessa A M; van Noorden, Tirza H J; Deutz, Marike H F

2017-02-01

This study examined whether victimization is associated with negatively distorted social cognition (bias), or with a specific increased sensitivity to social negative cues, by assessing the perception of social exclusion and the consequences for psychological well-being (moods and fundamental needs). Both self-reported and peer-reported victimization of 564 participants (M age =9.9years, SD=1.04; 49.1% girls) were measured, and social exclusion was manipulated through inclusion versus exclusion in a virtual ball-tossing game (Cyberball). Children's perceptions and psychological well-being were in general more negative after exclusion than after inclusion. Moreover, self-reported-but not peer-reported-victimization was associated with the perception of being excluded more and receiving the ball less, as well as more negative moods and less fulfillment of fundamental needs, regardless of being excluded or included during the Cyberball game. In contrast, peer-reported victimization was associated with more negative mood and lower need fulfillment in the exclusion condition only. Together, these results suggest that children who themselves indicate being victimized have negatively distorted social cognition, whereas children who are being victimized according to their peers experience increased sensitivity to negative social situations. The results stress the importance of distinguishing between self-reported and peer-reported victimization and have implications for interventions aimed at victimized children's social cognition.

Theory of own mind in autism: Evidence of a specific deficit in self-awareness?

Science.gov (United States)

Williams, David

2010-09-01

Assuming that self-awareness is not a unitary phenomenon, and that one can be aware of different aspects of self at any one time, it follows that selective impairments in self-awareness can occur. This article explores the idea that autism involves a particular deficit in awareness of the 'psychological self', or 'theory of own mind'. This hypothesised deficit renders individuals with autism spectrum disorder (ASD) at least as impaired at recognising their own mental states as at recognising mental states in other people. This deficit, it is argued, stands in contrast to an apparently typical awareness of the 'physical self' amongst people with autism. Theoretical implications of the empirical evidence are discussed.

Parents become emotionally upset when learning that their child has type 1 diabetes, yet they are expected to quickly learn functional diabetes management. The purpose of this article is to describe the application of self-regulation theory to guide a family-focused education intervention using human patient simulation to enhance the initial education of parents in diabetes management. A brief description is provided of the intervention framed by self-regulation theory. On the basis of the literature, we describe the educational vignettes used based on self-regulation in the randomized controlled trial entitled "Parent Education Through Simulation-Diabetes." Examples of theory-in-practice will be illustrated by parental learning responses to this alternative educational innovation.

This paper proposes that the philosophy of Bernard Lonergan can provide insight into the challenge of integrating nursing theory, research and practice. The author discusses Lonergan's work in regard to reflective understanding, authenticity and the human person as a subject of consciously developing unity. This is followed by a discussion of two key elements in Lonergan's work that relate to nursing: the subject-object challenge of nursing inquiry and common sense vs. scientific knowledge. The author suggests that integration of nursing theory, science and practice may be achieved through self-transcendence.

Thompson, Brad; Dabiri, Dana

2005-11-01

THE PROBLEM: Tail buffeting is a severe operational and maintenance problem in twin-tailed aircraft. Tail buffeting is driven by aerodynamic forces resulting from the wing leading edge produced concentrated vortices and their subsequent abrupt breakdown and radial expansion. The expansion leads to large-diameter helical vortices, which impose lateral forces on the tails. Various brute-force, empirical approaches have provided some ad-hoc fixes, but poor understanding of the underlying physics prevents effective design solutions. It is not yet possible to design buffet-free aircraft from first principles. Preliminary work offers a unique explanation for vortex breakdown called the azimuthal vorticity gradient theory ...(Cain 2001). This paper will present and establish experimental evidence using DPIV to validate this recent theory. Cain, C. B. (2001). The Self-Induction Theory of Vortex Breakdown. Aeronautics Dept.

Wu, Sangwook

2009-03-01

We investigate dynamical self-arrest in a diblock copolymer melt using a replica approach within a self-consistent local method based on dynamical mean-field theory (DMFT). The local replica approach effectively predicts (chiN)_{A} for dynamical self-arrest in a block copolymer melt for symmetric and asymmetric cases. We discuss the competition of the cubic and quartic interactions in the Landau free energy for a block copolymer melt in stabilizing a glassy state depending on the chain length. Our local replica theory provides a universal value for the dynamical self-arrest in block copolymer melts with (chiN)_{A} approximately 10.5+64N;{-3/10} for the symmetric case.
A self-consistent mean field theory for diffusion in alloys

International Nuclear Information System (INIS)

Nastar, M.; Barbe, V.

2007-01-01

Starting from a microscopic model of the atomic transport via vacancies and interstitials in alloys, a self-consistent mean field (SCMF) kinetic theory yields the phenomenological coefficients L ij . In this theory, kinetic correlations are accounted for through a set of effective interactions within a non-equilibrium distribution function of the system. The introduction of a master equation describing the evolution with time of the distribution function and its moments leads to general self-consistent kinetic equations. The L ij of a face centered cubic alloy are calculated using the kinetic equations of Nastar (M. Nastar, Philos. Mag., 2005, 85, 3767, ref. 1) derived from a microscopic broken bond model of the vacancy jump frequency. A first approximation leads to an analytical expression of the L ij and a second approximation to a better agreement with the Monte Carlo simulations. A change of sign of the L ij is studied as a function of the microscopic parameters of the jump frequency. The L ij of a cubic centered alloy obtained for the complex diffusion mechanism of the dumbbell configuration of the interstitial are used to study the effect of an on-site rotation of the dumbbell on the transport.

The impact of the self-interaction error on the density functional theory description of dissociating radical cations: ionic and covalent dissociation limits.

Science.gov (United States)

Gräfenstein, Jürgen; Kraka, Elfi; Cremer, Dieter

2004-01-08

Self-interaction corrected density functional theory was used to determine the self-interaction error for dissociating one-electron bonds. The self-interaction error of the unpaired electron mimics nondynamic correlation effects that have no physical basis where these effects increase for increasing separation distance. For short distances the magnitude of the self-interaction error takes a minimum and increases then again for decreasing R. The position of the minimum of the magnitude of the self-interaction error influences the equilibrium properties of the one-electron bond in the radical cations H2+ (1), B2H4+ (2), and C2H6+ (3), which differ significantly. These differences are explained by hyperconjugative interactions in 2 and 3 that are directly reflected by the self-interaction error and its orbital contributions. The density functional theory description of the dissociating radical cations suffers not only from the self-interaction error but also from the simplified description of interelectronic exchange. The calculated differences between ionic and covalent dissociation for 1, 2, and 3 provide an excellent criterion for determining the basic failures of density functional theory, self-interaction corrected density functional theory, and other methods. Pure electronic, orbital relaxation, and geometric relaxation contributions to the self-interaction error are discussed. The relevance of these effects for the description of transition states and charge transfer complexes is shown. Suggestions for the construction of new exchange-correlation functionals are given. In this connection, the disadvantages of recently suggested self-interaction error-free density functional theory methods are emphasized. (c) 2004 American Institute of Physics

Full Text Available Teachers perform numerous professional roles that can serve as the source of prolonged stress and lead to the occurrence of burnout syndrome. This research was aimed at studying the personal factors of burnout, using self-determination theory as a starting point. We used a sample of 200 teachers to study the following: the level of satisfaction of basic psychological needs at work, the prominence of self-orientations and the presence of burnout syndrome. We also studied whether these variables were significant burnout predictors, as well as whether there was a difference in the pattern of personal burnout predictors in primary school and university teachers. The following instruments were used: the scale of satisfaction of basic psychological needs at work, the ego function questionnaire, the scale of burnout syndrome in teachers. The results point to a relatively moderate satisfaction of all psychological needs, a higher level of integrated self-regulation as well as the medium presence of ego-invested and impersonal orientations. On the whole, teachers showed low burnout. Significant burnout predictors include an integrated self and the need for autonomy (university teachers and an impersonal self (primary school teachers. This implies that teachers whose psychological needs are satisfied and who have an integrated self are less susceptible to burnout. The findings are discussed from the viewpoint of the self-determination theory, their educational implications and the possibility of preventing work burnout in education workers.

Effects of Self-Similar Collisions in the Theory of Pressure Broadening and Shift

International Nuclear Information System (INIS)

Kharintsev, S.S.; Salakhov, M.Kh.

1999-01-01

In the present paper the self-similar collision model is developed in terms of fractal Brownian motion. Within this model framework, collisions are assumed to carry a non-Markovian character and, therefore, possible memory collisional effects are not taken into account. Applying a self-similar collision model for the motion of the radiator and Anderson-Talman phase-shift theory of collisional broadening, a general formula for the correlation function in the impact limit is described.

Mode coupling theory for nonequilibrium glassy dynamics of thermal self-propelled particles.

Feng, Mengkai; Hou, Zhonghuai

2017-06-28

We present a mode coupling theory study for the relaxation and glassy dynamics of a system of strongly interacting self-propelled particles, wherein the self-propulsion force is described by Ornstein-Uhlenbeck colored noise and thermal noises are included. Our starting point is an effective Smoluchowski equation governing the distribution function of particle positions, from which we derive a memory function equation for the time dependence of density fluctuations in nonequilibrium steady states. With the basic assumption of the absence of macroscopic currents and standard mode coupling approximation, we can obtain expressions for the irreducible memory function and other relevant dynamic terms, wherein the nonequilibrium character of the active system is manifested through an averaged diffusion coefficient D[combining macron] and a nontrivial structural function S 2 (q) with q being the magnitude of wave vector q. D[combining macron] and S 2 (q) enter the frequency term and the vertex term for the memory function, and thus influence both the short time and the long time dynamics of the system. With these equations obtained, we study the glassy dynamics of this thermal self-propelled particle system by investigating the Debye-Waller factor f q and relaxation time τ α as functions of the persistence time τ p of self-propulsion, the single particle effective temperature T eff as well as the number density ρ. Consequently, we find the critical density ρ c for given τ p shifts to larger values with increasing magnitude of propulsion force or effective temperature, in good accordance with previously reported simulation work. In addition, the theory facilitates us to study the critical effective temperature T for fixed ρ as well as its dependence on τ p . We find that T increases with τ p and in the limit τ p → 0, it approaches the value for a simple passive Brownian system as expected. Our theory also well recovers the results for passive systems and can be

Although theories that examine direct links between behavior and brain remain incomplete, it is known that brain expansion significantly correlates with caloric and oxygen demands. Therefore, one of the principles governing evolutionary cognitive neuroscience is that cognitive abilities that require significant brain function (and/or structural support) must be accompanied by significant fitness benefit to offset the increased metabolic demands. One such capacity is self-awareness (SA), which (1) is found only in the greater apes and (2) remains unclear in terms of both cortical underpinning and possible fitness benefit. In the current experiment, transcranial magnetic stimulation (TMS) was applied to the prefrontal cortex during a spatial perspective-taking task involving self and other viewpoints. It was found that delivery of TMS to the right prefrontal region disrupted self-, but not other-, perspective. These data suggest that self-awareness may have evolved in concert with other right hemisphere cognitive abilities.

2010-06-01

The present study aimed to delineate the psychological structure of materialism and intrinsic and extrinsic value pursuit. Moreover, we compared models based on self-determination theory (SDT), Fromm's marketing character, and Inglehart's theory of social change to account for racial prejudice. In a sample of undergraduate students (n=131) and adults (n=176) it was revealed that the extrinsic value pursuit Financial Success/Materialism could be distinguished from the extrinsic value scales Physical Appeal and Social Recognition, and Community Concern could be distinguished from the intrinsic value pursuit scales Self-acceptance and Affiliation. Moreover, Financial Success/Materialism and Community Concern were consistently and significantly related to prejudice, whereas the other SDT facet scales yielded weaker relationships with prejudice. Structural models based on SDT and Inglehart were not corroborated, but instead the present data supported a mediation model based on Fromm's work in which the effect of Community Concern was mediated by Financial Success/Materialism. Broader implications for SDT are critically assessed.

We use the full multiple scattering expansion of the retarded self-energy to obtain the gain and loss rates present in the Kadanoff-Baym relativistic transport equation. The rates we obtain include processes with any number of particles. As a first approximation, we only consider central cuts in the self-energies, but otherwise our results are general. We specialize to the case of scalar field theory to compare with lowest order results. The main application of this work is relativistic transport theory of very dense systems, such as the quark-gluon plasma or the early universe, where multi-particle interactions are important.

2017-02-01

Full Text Available Background: The principle of transient ischemic attack treatment is lifestyle modification and pharmacological treatment that would reduce recurrence and incidence of stroke. Lifestyle changes require follow-up care and continuity of nurse and patient relationships, but the current training does not meet this need. The trainings based on motivating theory such as self-determination, besides continuity of the relationship with patient, improve his/her incentive, specially of it is carried out at the discharge time. Therefore, this study has been done by the purpose of defining the impact of discharge plan based on self-determination theory on the lifestyle patients with transient ischemic attack. Methodology: The analysis has been done on 57, 18-90 years old clinical random patients in Tehran hospitals (29 cases and 28 controls in 2015. Data were collected by demographic questionnaire at the beginning and health-promoting lifestyle questionnaire(second edition were collected at the end of the study. Discharge plan based on self-determination theory, including patients and families meeting in hospital and telephone counseling during the 12 weeks after discharge was accomplished in cases group. The control group received only routine hospital care. Data were analyzed by t-test and chi- squre test. Results: The score of lifestyle was similar in both groups (p> .05 at beginning of the study, but at the end of the study, the average score of cases group (17.1 ± 164.2 significantly higher than the control group (17.6 ± 118.3 (p < 0.001. Furthermore, At the end of study, the mean scores of nutrition, physical activity, stress management, interpersonal relationships, spiritual growth and responsibility in the lifestyle cases group was significantly higher than the control group (p <.001.

Continuous performing of diabetes self-care behaviors was shown to be an effective strategy to control diabetes and to prevent or reduce its- related complications. This study aimed to investigate predictors of self-care behavior based on the extended theory of reasoned action by self efficacy (ETRA) among women with type 2 diabetes in Iran. A sample of 352 women with type 2 diabetes, referring to a Diabetes Clinic in Khoy, Iran using the nonprobability sampling was enrolled. Appropriate instruments were designed to measure the variables of interest (diabetes knowledge, personal beliefs, subjective norm, self-efficacy and behavioral intention along with self- care behaviors). Reliability and validity of the instruments using Cronbach's alpha coefficients (the values of them were more than 0.70) and a panel of experts were tested. A statistical significant correlation existed between independent constructs of proposed model and modelrelated dependent constructs, as ETRA model along with its related external factors explained 41.5% of variance of intentions and 25.3% of variance of actual behavior. Among constructs of model, self-efficacy was the strongest predictor of intentions among women with type 2 diabetes, as it lonely explained 31.3% of variance of intentions and 11.4% of variance of self-care behavior. The high ability of the extended theory of reasoned action with self-efficacy in forecasting and explaining diabetes mellitus self management can be a base for educational intervention. So to improve diabetes self management behavior and to control the disease, use of educational interventions based on proposed model is suggested.
Women's self-management of chronic illnesses in the context of caregiving: a grounded theory study.

Martinez-Marcos, Mercedes; De la Cuesta-Benjumea, Carmen

2015-06-01

Uncover how women self-manage their own chronic illness while taking care of a dependent relative. International policies place special emphasis in promoting interventions addressed to control, prevent and care for people with chronic health conditions. Self-management is a crucial part of this care. Caregivers are more prone to have chronic illness than non-caregivers. They are confronted with dilemmas about taking care of themselves while taking care of their dependent relative and the rest of their families. Caregivers articulate strategies to enable them to focus their energy on caring. Qualitative study using constructivist grounded theory. Thirty-nine women caregivers with a chronic illness participated in the study. Twenty-three semi-structured interviews and two focus groups were carried out between April 2010-December 2011. Data were analysed using grounded theory procedures. Self-management helps women caregivers with a chronic illness to balance the demands of their own illness and those of the dependent relative. They self-manage their illness by self-regulating the treatment, by regulating their strength and by controlling their emotions. Women caregivers integrate effectively and creatively the management of their chronic illnesses within the complexities of family care. This renders their health needs invisible and reaffirms them as capable caregivers. Identifying self-management strategies of women caregivers allow health professionals to acknowledge and reinforce effective self-care measures and to deter those that are ineffective and lessen their quality of life. © 2014 John Wiley & Sons Ltd.
Leader--member exchange, differentiation, and psychological contract fulfillment: a multilevel examination.

Henderson, David J; Wayne, Sandy J; Shore, Lynn M; Bommer, William H; Tetrick, Lois E

2008-11-01

Prior integrations of the leader-member exchange (LMX) and psychological contract literatures have not clarified how within-group LMX differentiation influences employees' attitudes and behaviors in the employment relationship. Therefore, using a sample of 278 members and managers of 31 intact work groups at 4 manufacturing plants, the authors examined how LMX operating at the within-group level (relative LMX, or RLMX) and the group level influenced perceptions of psychological contract fulfillment and employee-level outcomes. Controlling for individual-level perceptions of LMX quality, results indicated a positive relationship between RLMX and fulfillment, which was strengthened as group-level variability in LMX quality increased. Perceptions of fulfillment mediated the relationship between RLMX and performance and sportsmanship behaviors. The importance of conceptualizing LMX as simultaneously operating at multiple levels is highlighted.

Van Petegem, Stijn; Soenens, Bart; Vansteenkiste, Maarten; Beyers, Wim

2015-01-01

The present investigation focused on adolescents' defiance against parents by drawing upon psychological reactance theory (Brehm, 1966) and self-determination theory (Ryan & Deci, 2000). Psychological reactance would be elicited when freedom is taken away, thereby motivating individuals to engage in oppositional behavior. Throughout four studies (total N = 1,472, age ranging between 12 and 21 years), it was examined whether a controlling parenting style related to adolescents' experiences of autonomy need frustration (i.e., pressure) and reactance. Reactance, in turn, would relate to more externalizing and internalizing problems. Support was obtained for these associations in community and clinical samples, making use of different informants, and controlling for responsiveness and rule setting. A vignette-based study provided further support. The discussion highlights theoretical and clinical implications. © 2015 The Authors.

2017-07-01

For the past 40 years, the conventional univariate model of self-monitoring has reigned as the dominant interpretative paradigm in the literature. However, recent findings associated with an alternative bivariate model challenge the conventional paradigm. In this study, item response theory is used to develop measures of the bivariate model of acquisitive and protective self-monitoring using original Self-Monitoring Scale (SMS) items, and data from two large, nonstudent samples ( Ns = 13,563 and 709). Results indicate that the new acquisitive (six-item) and protective (seven-item) self-monitoring scales are reliable, unbiased in terms of gender and age, and demonstrate theoretically consistent relations to measures of personality traits and cognitive ability. Additionally, by virtue of using original SMS items, previously collected responses can be reanalyzed in accordance with the alternative bivariate model. Recommendations for the reanalysis of archival SMS data, as well as directions for future research, are provided.

Full Text Available Tourism has been indicated as alternative of economic growth without environmental degradation. However, there are evidences that tourism - considered a “clean” alternative of economic growth - can cause pollution. In this context, this article had the objective to analyze actions to fulfill environmental law in four hotel organizations. Methodology came from a multiple case study, carried through in four hotel organizations located in the Brazilian state of Santa Catarina. Data had been collected by non-participant observation, and by structuralized interview. The results indicated that those organizations fulfilled the law disposals applicable to them. It is concluded that the adequacy to the environmental law must be kept, to prevent the imposition of legal sanctions.
Self-consistent field theory of polymer-ionic molecule complexation.

Science.gov (United States)

Nakamura, Issei; Shi, An-Chang

2010-05-21

A self-consistent field theory is developed for polymers that are capable of binding small ionic molecules (adsorbates). The polymer-ionic molecule association is described by Ising-like binding variables, C(i) ((a))(kDelta)(=0 or 1), whose average determines the number of adsorbed molecules, n(BI). Polymer gelation can occur through polymer-ionic molecule complexation in our model. For polymer-polymer cross-links through the ionic molecules, three types of solutions for n(BI) are obtained, depending on the equilibrium constant of single-ion binding. Spinodal lines calculated from the mean-field free energy exhibit closed-loop regions where the homogeneous phase becomes unstable. This phase instability is driven by the excluded-volume interaction due to the single occupancy of ion-binding sites on the polymers. Moreover, sol-gel transitions are examined using a critical degree of conversion. A gel phase is induced when the concentration of adsorbates is increased. At a higher concentration of the adsorbates, however, a re-entrance from a gel phase into a sol phase arises from the correlation between unoccupied and occupied ion-binding sites. The theory is applied to a model system, poly(vinyl alcohol) and borate ion in aqueous solution with sodium chloride. Good agreement between theory and experiment is obtained.

[Dying well seen in the light of self-transcendence and transition : two theories of care helpful to nurses].

Science.gov (United States)

Laporte, Pauline; Vonarx, Nicolas

2016-06-01

Accompanying a dying person up to and at the actual moment of death is a duty that often leaves carers at a loss. We shall show how far theoretical nursing knowledge can help practitioners who accompany the end of life by applying two theories of care : Reed’s theory of self-transcendence and Meleis’s theory of transition. Our interpretation of the theory of self-transcendence designates three points of reference in the concept of dying well. The first relates to the overtures prompted by the vulnerability that the context of dying inspires. The second concerns the capacity of the patient to summon up intrapersonal, interpersonal and transpersonal strategies, and the third considers the benefits when self-transcendence is achieved. The theory of transition similarly presents three points of reference. The first is based on informing the patient about palliative care and telling him or her the truth about the prognosis. The second relates to coordinating the interprofessional team that is looking after the dying person. The last criterion is that the palliative care should be started at a suitable moment. This makes it possible to educate a patient who wishes to die at home and thus create an environment favourable to the transition.
Electron confinement in quantum nanostructures: Self-consistent Poisson-Schroedinger theory

International Nuclear Information System (INIS)

Luscombe, J.H.; Bouchard, A.M.; Luban, M.

1992-01-01

We compute the self-consistent electron states and confining potential, V(r,T), for laterally confined cylindrical quantum wires at a temperature T from a numerical solution of the coupled Poisson and Schroedinger (PS) equations. Finite-temperature effects are included in the electron density function, n(r,T), via the single-particle density matrix in the grand-canonical ensemble using the self-consistent bound states. We compare our results for a GaAs quantum wire with those obtained previously [J. H. Luscombe and M. Luban, Appl. Phys. Lett. 57, 61 (1990)] from a finite-temperature Thomas-Fermi (TF) approximation. We find that the TF results agree well with those of the more realistic, but also more computationally intensive PS theory, except for low temperatures or for cases where the quantum wire is almost, but not totally, depleted due to a combination of either small geometry, surface boundary conditions, or low doping concentrations. In the latter situations, the number of subbands that are populated is relatively small, and both n(r,T) and V(r,T) exhibit Friedel-type oscillations. Otherwise the TF theory, which is based on free-particle states, is remarkably accurate. We also present results for the partial electron density functions associated with the angular momentum quantum numbers, and discuss their role in populating the quantum wire
Self-dual phase space for (3 +1 )-dimensional lattice Yang-Mills theory

Science.gov (United States)

Riello, Aldo

2018-01-01

I propose a self-dual deformation of the classical phase space of lattice Yang-Mills theory, in which both the electric and magnetic fluxes take value in the compact gauge Lie group. A local construction of the deformed phase space requires the machinery of "quasi-Hamiltonian spaces" by Alekseev et al., which is reviewed here. The results is a full-fledged finite-dimensional and gauge-invariant phase space, the self-duality properties of which are largely enhanced in (3 +1 ) spacetime dimensions. This enhancement is due to a correspondence with the moduli space of an auxiliary noncommutative flat connection living on a Riemann surface defined from the lattice itself, which in turn equips the duality between electric and magnetic fluxes with a neat geometrical interpretation in terms of a Heegaard splitting of the space manifold. Finally, I discuss the consequences of the proposed deformation on the quantization of the phase space, its quantum gravitational interpretation, as well as its relevance for the construction of (3 +1 )-dimensional topological field theories with defects.
Integrating Self-Determination and Job Demands-Resources Theory in Predicting Mental Health Provider Burnout.

Science.gov (United States)

Dreison, Kimberly C; White, Dominique A; Bauer, Sarah M; Salyers, Michelle P; McGuire, Alan B

2018-01-01

Limited progress has been made in reducing burnout in mental health professionals. Accordingly, we identified factors that might protect against burnout and could be productive focal areas for future interventions. Guided by self-determination theory, we examined whether supervisor autonomy support, self-efficacy, and staff cohesion predict provider burnout. 358 staff from 13 agencies completed surveys. Higher levels of supervisor autonomy support, self-efficacy, and staff cohesion were predictive of lower burnout, even after accounting for job demands. Although administrators may be limited in their ability to reduce job demands, our findings suggest that increasing core job resources may be a viable alternative.

2013-01-01

We present the time-dependent restricted-active-space self-consistent-field (TD-RASSCF) theory as a framework for the time-dependent many-electron problem. The theory generalizes the multiconfigurational time-dependent Hartree-Fock (MCTDHF) theory by incorporating the restricted-active-space scheme...... well known in time-independent quantum chemistry. Optimization of the orbitals as well as the expansion coefficients at each time step makes it possible to construct the wave function accurately while using only a relatively small number of electronic configurations.

General Theory versus ENA Theory: Comparing Their Predictive Accuracy and Scope.

Ellis, Lee; Hoskin, Anthony; Hartley, Richard; Walsh, Anthony; Widmayer, Alan; Ratnasingam, Malini

2015-12-01

General theory attributes criminal behavior primarily to low self-control, whereas evolutionary neuroandrogenic (ENA) theory envisions criminality as being a crude form of status-striving promoted by high brain exposure to androgens. General theory predicts that self-control will be negatively correlated with risk-taking, while ENA theory implies that these two variables should actually be positively correlated. According to ENA theory, traits such as pain tolerance and muscularity will be positively associated with risk-taking and criminality while general theory makes no predictions concerning these relationships. Data from Malaysia and the United States are used to test 10 hypotheses derived from one or both of these theories. As predicted by both theories, risk-taking was positively correlated with criminality in both countries. However, contrary to general theory and consistent with ENA theory, the correlation between self-control and risk-taking was positive in both countries. General theory's prediction of an inverse correlation between low self-control and criminality was largely supported by the U.S. data but only weakly supported by the Malaysian data. ENA theory's predictions of positive correlations between pain tolerance, muscularity, and offending were largely confirmed. For the 10 hypotheses tested, ENA theory surpassed general theory in predictive scope and accuracy. © The Author(s) 2014.
Theory of weakly nonlinear self-sustained detonations

KAUST Repository

Faria, Luiz

2015-11-03

We propose a theory of weakly nonlinear multidimensional self-sustained detonations based on asymptotic analysis of the reactive compressible Navier-Stokes equations. We show that these equations can be reduced to a model consisting of a forced unsteady small-disturbance transonic equation and a rate equation for the heat release. In one spatial dimension, the model simplifies to a forced Burgers equation. Through analysis, numerical calculations and comparison with the reactive Euler equations, the model is demonstrated to capture such essential dynamical characteristics of detonations as the steady-state structure, the linear stability spectrum, the period-doubling sequence of bifurcations and chaos in one-dimensional detonations and cellular structures in multidimensional detonations.
Mode-coupling theory of self-diffusion in diblock copolymers. II. Model calculations and experimental comparisons

International Nuclear Information System (INIS)

Guenza, M.; Schweizer, K.S.

1998-01-01

The predictions of polymer-mode-coupling theory for self-diffusion in entangled structurally and interaction symmetric diblock copolymer fluids are illustrated by explicit numerical calculations. We find that retardation of translational motion emerges near and somewhat below the order endash disorder transition (ODT) in an approximately exponential and/or thermally activated manner. At fixed reduced temperature, suppression of diffusion is enhanced with increasing diblock molecular weight, compositional symmetry, and/or copolymer concentration. At very low temperatures, a new entropic-like regime of mobility suppression is predicted based on an isotropic supercooled liquid description of the copolymer structure. Preliminary generalization of the theory to treat diblock tracer diffusion is also presented. Quantitative applications to recent self and tracer diffusion measurements on compositionally symmetric polyolefin diblock materials have been carried out, and very good agreement between theory and experiment is found. Asymmetry in block local friction constants is predicted to significantly influence mobility suppression, with the largest effects occurring when the minority block is also the high friction species. New experiments to further test the predictions of the theory are suggested. copyright 1998 American Institute of Physics
Self-interacting, boson, quantum field theory, and the thermodynamic limit in d dimensions

International Nuclear Information System (INIS)

Baker, G.A. Jr.

1975-01-01

By use of a finite volume, lattice approximation, an approximation to the analytic continuation of a polynomial, self-interacting boson quantum field theory from Minkowski space to Euclidean space was set up. The infinite volume limit for various boundary conditions is shown to exist and to be asymptotic to the perturbation expansion in the coupling constant g at g = 0. For g: phi 4 : d theory mass renormalizability is proved and it is shown how, by use of Nelson's reconstruction theorem, the corresponding Minkowski space quantum field theory can be obtained. It is discussed, at least for d greater than or equal to 4, how statistical mechanical techniques, used to analyze the Ising model in the critical region just above the critical temperature, can be used to compute the properties of quantum field theory.

2009-01-01

The fascination of venture creation is associated with an entrepreneur’s opportunity of achieving personal fulfillment. In reality, however, many nascent entrepreneurs discover that much of their original vision is sacrificed in the process of creating a startup. In this paper we address the conflict between the entrepreneur’s fulfillment and the startup’s competitiveness from a negotiationanalytic perspective. We show how the nature of this conflict is transformed in the process of business ...

From self to social cognition: Theory of Mind mechanisms and their relation to Executive Functioning.

'Theory of Mind' refers to the ability to attribute mental states to oneself and other people (Premack & Woodruff, 1978). This study examined the extent to which 'Self' and 'Other' belief-attribution processes within the Theory of Mind (ToM) mechanism could be distinguished behaviourally, and whether these separable components differentially related to Executive Functioning (EF) abilities. A computerized false-belief task, utilizing a matched-design to allow direct comparison of self-oriented vs. other-oriented belief-attribution, was used to assess ToM, and a face-image Stroop task was employed to assess EF, within a population of typically-developed adults. Results revealed significantly longer reaction times when attributing beliefs to other people as opposed to recognizing and attributing beliefs to oneself. Intriguingly, results revealed that 'perspective-shift' requirements (i.e. changing from adoption of the 'self' perspective to the perspective of the 'other', or vice versa) across false-belief trials influenced reaction times. Reaction times were significantly longer when the perspective shift was from self-to-other than from other-to-self. It is suggested that the 'self' forms the stem of understanding the 'other', and is therefore processed regardless of ultimate task demands; in contrast, the 'other' perspective is only processed when explicitly required. We conclude that adopting another person's perspective, even when their belief state is matched to one's own, requires more cognitive effort than recalling and reflecting on self-oriented belief-states.

Environmental catastrophes under time-inconsistent preference

Energy Technology Data Exchange (ETDEWEB)

Michielsen, T.

2013-02-15

I analyze optimal natural resource use in an intergenerational model with the risk of a catastrophe. Each generation maximizes a weighted sum of discounted utility (positive) and the probability that a catastrophe will occur at any point in the future (negative). The model generates time inconsistency as generations disagree on the relative weights on utility and catastrophe prevention. As a consequence, future generations emit too much from the current generation's perspective and a dynamic game ensues. I consider a sequence of models. When the environmental problem is related to a scarce exhaustible resource, early generations have an incentive to reduce emissions in Markov equilibrium in order to enhance the ecosystem's resilience to future emissions. When the pollutant is expected to become obsolete in the near future, early generations may however increase their emissions if this reduces future emissions. When polluting inputs are abundant and expected to remain essential, the catastrophe becomes a self-fulfilling prophecy and the degree of concern for catastrophe prevention has limited or even no effect on equilibrium behaviour.
The 'side effects' of medicalization: a meta-analytic review of how biogenetic explanations affect stigma.

Science.gov (United States)

Kvaale, Erlend P; Haslam, Nick; Gottdiener, William H

2013-08-01

Reducing stigma is crucial for facilitating recovery from psychological problems. Viewing these problems biomedically may reduce the tendency to blame affected persons, but critics have cautioned that it could also increase other facets of stigma. We report on the first meta-analytic review of the effects of biogenetic explanations on stigma. A comprehensive search yielded 28 eligible experimental studies. Four separate meta-analyses (Ns=1207-3469) assessed the effects of biogenetic explanations on blame, perceived dangerousness, social distance, and prognostic pessimism. We found that biogenetic explanations reduce blame (Hedges g=-0.324) but induce pessimism (Hedges g=0.263). We also found that biogenetic explanations increase endorsement of the stereotype that people with psychological problems are dangerous (Hedges g=0.198), although this result could reflect publication bias. Finally, we found that biogenetic explanations do not typically affect social distance. Promoting biogenetic explanations to alleviate blame may induce pessimism and set the stage for self-fulfilling prophecies that could hamper recovery from psychological problems.

Lay theories about social class buffer lower-class individuals against poor self-rated health and negative affect.

Tan, Jacinth J X; Kraus, Michael W

2015-03-01

The economic conditions of one's life can profoundly and systematically influence health outcomes over the life course. Our present research demonstrates that rejecting the notion that social class categories are biologically determined-a nonessentialist belief-buffers lower-class individuals from poor self-rated health and negative affect, whereas conceiving of social class categories as rooted in biology-an essentialist belief-does not. In Study 1, lower-class individuals self-reported poorer health than upper-class individuals when they endorsed essentialist beliefs but showed no such difference when they rejected such beliefs. Exposure to essentialist theories of social class also led lower-class individuals to report greater feelings of negative self-conscious emotions (Studies 2 and 3), and perceive poorer health (Study 3) than upper-class individuals, whereas exposure to nonessentialist theories did not lead to such differences. Discussion considers how lay theories of social class potentially shape long-term trajectories of health and affect of lower-class individuals. © 2015 by the Society for Personality and Social Psychology, Inc.
Personal and situational predictors of everyday snacking: An application of temporal self-regulation theory.

Science.gov (United States)

Elliston, Katherine G; Ferguson, Stuart G; Schüz, Benjamin

2017-11-01

This study aims at testing predictions derived from temporal self-regulation theory (TST) in relation to discretionary food choices (snacks). TST combines a motivational sphere of influence (cognitions and temporal valuations resulting in intentions) with a momentary sphere (encompassing social and physical environmental cues). This dual approach differs from current health behaviour theories, but can potentially improve our understanding of the interplay of personal and environmental factors in health behaviour self-regulation. A mixed event-based and time-based (Ecological Momentary Assessment) study in 61 adults aged between 18 and 64, with a BMI range between 18.34 and 39.78 (M = 25.66, SD = 4.82) over two weeks. Participants recorded their food and drink intake for two weeks in real time using electronic diaries. Participants also responded to non-consumption assessments at random intervals throughout each day. Momentary cues (individual, situational, and environmental factors) were assessed both during food logs and non-consumption assessments. Motivational factors, past behaviour, and trait self-regulation were assessed during baseline. Multilevel logistic regression analyses showed that across all snack types, environmental cues and negative affect were associated with an increased likelihood of snacking. Perceiving a cost of healthy eating to occur before eating was associated with an increased likelihood of snacking, whereas intentions and self-regulation were not. Discretionary food intake is largely guided by momentary cues, and motivational-level factors, such as intention and self-regulation, are less important in the initiation of discretionary food intake. Statement of contribution What is already known on this subject? Overweight and obesity are a result of prolonged periods of energy imbalance between energy intake and expenditure (Hill & Peters, ). One of the key behavioural determinants of energy imbalances results from food intake
Concept of self-employment

The article deals with the theories that explain the growth of self-employment and help to determine the presumptions of the self-employment growth. Self-employment theories are classified to several groups, i.e. the economic and sociological-psychological as well as the “push” and “pull” theories. Economic theories of self-employment interpret financial motives of the person to pursue own business, while sociologicalpsychological theories of self-employment determine non-financial objectives...

Evidence of improved fluid management in patients receiving haemodialysis following a self-affirmation theory-based intervention: A randomised controlled trial.

2016-01-01

Haemodialysis patients are at risk of serious health complications; yet, treatment non-adherence remains high. Warnings about health risks associated with non-adherence may trigger defensive reactions. We studied whether an intervention based on self-affirmation theory reduced resistance to health-risk information and improved fluid treatment adherence. In a cluster randomised controlled trial, 91 patients either self-affirmed or completed a matched control task before reading about the health-risks associated with inadequate fluid control. Patients' perceptions of the health-risk information, intention and self-efficacy to control fluid were assessed immediately after presentation of health-risk information. Interdialytic weight gain (IDWG), excess fluid removed during haemodialysis, is a clinical measure of fluid treatment adherence. IDWG data were collected up to 12 months post-intervention. Self-affirmed patients had significantly reduced IDWG levels over 12 months. However, contrary to predictions derived from self-affirmation theory, self-affirmed participants and controls did not differ in their evaluation of the health-risk information, intention to control fluid or self-efficacy. A low-cost, high-reach health intervention based on self-affirmation theory was shown to reduce IDWG over a 12-month period, but the mechanism by which this apparent behaviour change occurred is uncertain. Further work is still required to identify mediators of the observed effects.
Extension of lattice cluster theory to strongly interacting, self-assembling polymeric systems.

Science.gov (United States)

Freed, Karl F

2009-02-14

A new extension of the lattice cluster theory is developed to describe the influence of monomer structure and local correlations on the free energy of strongly interacting and self-assembling polymer systems. This extension combines a systematic high dimension (1/d) and high temperature expansion (that is appropriate for weakly interacting systems) with a direct treatment of strong interactions. The general theory is illustrated for a binary polymer blend whose two components contain "sticky" donor and acceptor groups, respectively. The free energy is determined as an explicit function of the donor-acceptor contact probabilities that depend, in turn, on the local structure and both the strong and weak interactions.

2013-01-01

Full Text Available This study was the first to explore factors associated with emotional burnout (EB among medical residents in Malaysia. A cross-sectional study was conducted in a universal sample of 205 medical residents in a Malaysian general hospital. The self-administered questionnaire used consisted of questions on sociodemographics and work characteristics, sources of job stress, professional fulfillment, engagement, and EB. EB was measured using the emotional exhaustion subscale, the Maslach Burnout Inventory (MBI. Mean (±SD age of the respondents was 26.5 (±1.6. The most common source of job stress was “fear of making mistakes.” Most of the participants were dissatisfied with the increase of residentship period from one year to two years. A high level of EB was reported by 36.6% of the respondents. In multivariate analysis, the most important correlates of EB were sources of job stress, professional fulfillment, and engagement. A high prevalence of EB was found among medical residents. Sociodemographic characteristics, performance pressure, and satisfaction with policies were significantly associated with EB. Although this study was limited by its cross-sectional design, its findings posit a sufficient foundation to relevant authorities to construct, amend, and amalgamate existing and future policies.

Non-topological solitons in field theories with kinetic self-coupling

International Nuclear Information System (INIS)

Diaz-Alonso, Joaquin; Rubiera-Garcia, Diego

2007-01-01

We investigate some fundamental features of a class of non-linear relativistic Lagrangian field theories with kinetic self-coupling. We focus our attention upon theories admitting static, spherically symmetric solutions in three space dimensions which are finite-energy and stable. We determine general conditions for the existence and stability of these non-topological soliton solutions. In particular, we perform a linear stability analysis that goes beyond the usual Derrick-like criteria. On the basis of these considerations we obtain a complete characterization of the soliton-supporting members of the aforementioned class of non-linear field theories. We then classify the family of soliton-supporting theories according to the central and asymptotic behaviors of the soliton field, and provide illustrative explicit examples of models belonging to each of the corresponding sub-families. In the present work we restrict most of our considerations to one and many-components scalar models. We show that in these cases the finite-energy static spherically symmetric solutions are stable against charge-preserving perturbations, provided that the vacuum energy of the model vanishes and the energy density is positive definite. We also discuss briefly the extension of the present approach to models involving other types of fields, but a detailed study of this more general scenario will be addressed in a separate publication

Self-patterning presents an appealing alternative to lithography for the production of arrays of nanoscale ferroelectric capacitors for use in high density non-volatile memory devices. However current levels of registration achieved experimentally are far from adequate for this application. To provide a guide for experiment we have applied the theories developed for self-patterning of semiconductor nanocrystals to two self-patterning systems of potential interest for ferroelectric memory applications, metallic bismuth oxide on bismuth titanate and ferroelectric lead zirconate titanate on strontium titanate.

Self-care needs in healthcare contexts: how to gather, read and fulfill them

Directory of Open Access Journals (Sweden)

Lucia Zannini

2014-12-01

Full Text Available In light of a continuing education intervention (entitled “On the other side” conducted with a multi-professional group at a Northern Italian hospital, this paper offers a reflection on educational needs analysis for healthcare professionals. This process has been extensively investigated, including in the context of healthcare training, leading to the call for a multi-method approach to developing professionals’ competencies in the interest of optimizing their patients’ health and quality of life. However, when professionals’ deepest inner need is for self-care to help them cope with the perceived heavy demands of clinical practice, educators may usefully adopt the phenomenological approach, which involves bracketing, the ability to see, taking responsibility and attending to professionals’ emotional experience. The analysis of professionals’ self-care needs should be viewed as a continuous process, to be implemented on an ongoing basis throughout the entire educational intervention, and as a practice that itself requires a caring attitude.

Mental and emotional self-help apps have emerged as potential mental illness prevention and treatment tools. The health behavior theory mechanisms by which these apps influence mental health-related behavior change have not been thoroughly examined. The objective of this study was to examine the association between theoretical behavior change mechanisms and use of mental and emotional self-help apps and whether the use of such apps is associated with mental health behaviors. This study utilized a cross-sectional survey of 150 users of mental or emotional health apps in the past 6 months. Survey questions included theory-based items, app engagement and likeability items, and behavior change items. Stata version 14 was used to calculate all statistics. Descriptive statistics were calculated for each of the demographic, theory, engagement, and behavior variables. Multiple regression analysis was used to identify factors associated with reported changes in theory and separately for reported changes in actual behavior after controlling for potentially confounding variables. Participants reported that app use increased their motivation, desire to set goals, confidence, control, and intentions to be mentally and emotionally healthy. Engagement (Ptheory items, whereas perceived behavior change was positively associated with theory (Ptheory items. Future efforts should consider the value of impacting key theoretical constructs when designing mental and emotional health apps. As apps are evaluated and additional theory-based apps are created, cost-effective self-help apps may become common preventative and treatment tools in the mental health field. ©Benjamin T Crookston, Joshua H West, P Cougar Hall, Kaitana Martinez Dahle, Thomas L Heaton, Robin N Beck, Chandni Muralidharan.

2015-01-01

Full Text Available This paper has tested the most frequently used instrument for assessing academic motivation in adolescents, which measures seven aspects of motivation in accordance with the self-determination theory. In the first version of this questionnaire, four factors were singled out in the Serbian sample. Based on the first version, the second one was made under the name AMS, containing 32 items with five-degree categories of answers ranging from total disagreement to total agreement. The AMS questionnaire was administered on the convenient sample of 1.106 respondents aged 10 to 15 of both genders (51% female. Four factors were extracted, defined as Internal motivation, External motivation, Introjected motivation and Amotivation. The self-determination continuum has not been confirmed completely since some dimensions have a different status of self-determination than it was expected, while psychometric characteristics of the scales proved to be very good. Compared to the first version, this version of the questionnaire has better psychometric characteristics, reflects more clearly the theoretical assumption about the aspects of academic motivation and partially confirms its continuum. Hence, it can be stated that the AMS questionnaire is a good enough indicator of academic motivation in early adolescence.

Self-interaction error in density functional theory: a mean-field correction for molecules and large systems

Ciofini, Ilaria; Adamo, Carlo; Chermette, Henry

2005-01-01

Corrections to the self-interaction error which is rooted in all standard exchange-correlation functionals in the density functional theory (DFT) have become the object of an increasing interest. After an introduction reminding the origin of the self-interaction error in the DFT formalism, and a brief review of the self-interaction free approximations, we present a simple, yet effective, self-consistent method to correct this error. The model is based on an average density self-interaction correction (ADSIC), where both exchange and Coulomb contributions are screened by a fraction of the electron density. The ansatz on which the method is built makes it particularly appealing, due to its simplicity and its favorable scaling with the size of the system. We have tested the ADSIC approach on one of the classical pathological problem for density functional theory: the direct estimation of the ionization potential from orbital eigenvalues. A large set of different chemical systems, ranging from simple atoms to large fullerenes, has been considered as test cases. Our results show that the ADSIC approach provides good numerical values for all the molecular systems, the agreement with the experimental values increasing, due to its average ansatz, with the size (conjugation) of the systems

2007-10-01

Guided by Self-Determination Theory (SDT), the present study examined the sport motivation and coping skills of male and female wheelchair basketball players with and without disability (N = 72). In line with SDT, results showed that intrinsic and extrinsic motivation as well as amotivation was found to be present in this sample of wheelchair basketball players. Results also demonstrated that the participants surveyed in the present study scored higher on self-determined types of motivation than non self-determined types of motivation, thus replicating past research with athletes without disability. Furthermore, wheelchair basketball players with and without disability did not differ significantly with respect to sport motivation and coping skills, suggesting that they are more alike than dissimilar. Finally, results revealed that self-determined motivation is associated with enhanced psychological functioning.
Self-determination theory and the facilitation of intrinsic motivation, social development, and well-being.

Science.gov (United States)

Ryan, R M; Deci, E L

2000-01-01

Human beings can be proactive and engaged or, alternatively, passive and alienated, largely as a function of the social conditions in which they develop and function. Accordingly, research guided by self-determination theory has focused on the social-contextual conditions that facilitate versus forestall the natural processes of self-motivation and healthy psychological development. Specifically, factors have been examined that enhance versus undermine intrinsic motivation, self-regulation, and well-being. The findings have led to the postulate of three innate psychological needs--competence, autonomy, and relatedness--which when satisfied yield enhanced self-motivation and mental health and when thwarted lead to diminished motivation and well-being. Also considered is the significance of these psychological needs and processes within domains such as health care, education, work, sport, religion, and psychotherapy.

In this work we present homogeneous and isotropic cosmological solutions for the low energy limit of string theory with a self interacting potential for the scalar field. For a potential that is a linear combination of two exponential, a family of exact solutions are found for the different spatial curvatures. Among this family a non singular accelerating solution for positive curvature is singled out and the violation of the energy conditions for that solution is studied, and also its astrophysical consequences. The string coupling for this solution is finite. (Author)
Minimal theory of quantum electrodynamics

Berrondo, M.; Jauregui, R.

1986-01-01

Within the general framework of the Lehmann-Symanzik-Zimmermann axiomatic field theory, we obtain a simple and coherent formulation of quantum electrodynamics. The definitions of the current densities fulfill the one-particle stability condition, and the commutation relations for the interacting fields are obtained rather than being postulated a priori, thus avoiding the inconsistencies which appear in the canonical formalism. This is possible due to the fact that we use the integral form of the equations of motion in order to compute the propagators and the S matrix. The resulting spectral representations automatically fulfill the correct boundary conditions thus fixing the ubiquitous quasilocal operators in a unique fashion

Heerey, Erin A; Keltner, Dacher; Capps, Lisa M

2003-12-01

Self-conscious emotions such as embarrassment and shame are associated with 2 aspects of theory of mind (ToM): (a) the ability to understand that behavior has social consequences in the eyes of others and (b) an understanding of social norms violations. The present study aimed to link ToM with the recognition of self-conscious emotion. Children with and without autism identified facial expressions conscious of self-conscious and non-self-conscious emotions from photographs. ToM was also measured. Children with autism performed more poorly than comparison children at identifying self-conscious emotions, though they did not differ in the recognition of non-self-conscious emotions. When ToM ability was statistically controlled, group differences in the recognition of self-conscious emotion disappeared. Discussion focused on the links between ToM and self-conscious emotion.

Rogue States as the Stigmatized Members of International Society

Full Text Available At the turn of the century, the rogue state concept has become an integral part of the theory of international relations. However, even contemporary approaches lack the appropriate academic tools to reach a comprehensive understanding of the international community’s role in determining the normative frameworks of the proper behavior of the states as the main actors of international system, leaving the relations between global community and the rogues almost an uncharted territory on the international stage. The article considers the category of rogue states as “excluded” members of the international community through the sociological lens of “stigma” (E. Goffman and “labelling theory” (H. Becker and E. Lemert. Engaging an empirical case of Iraqi foreign policy during and after the Gulf War 1991, the author demonstrates two thresholds of the labelling state as the rogue: public initiation of the offender and self-fulfilling prophecy. It is possible to define some specific features of the outsider’s behavior on the international stage: the high level of cooperation among the representatives of the same category, “unsustainable bravado” as the set of fluid and inconsistent actions of the rogue state in foreign policy, finally, the tendency toward obtaining the “secondary gains”. Contrariwise, global community tends to pay greater attention to rogue states and exercise some discrimination practices on the ground of their outcast position in the world normative structure with the category of “wise” actors, for example China, being an exception from the common mainstream and maintaining close cooperation ties with rogues.
Individuals’ Motivation to Participate in Sport Tourism: A Self-Determination Theory Perspective

OpenAIRE

Thomas J. Aicher; Jessica Brenner

2015-01-01

Using self-determination theory (SDT) as a conceptual framework, we utilized previous research to develop a conceptual model to better understand individuals’ motivation to participate in sport tourism and events. The model represents the six propositions we put forward that depict the relationships between motivational factors associated with sport tourism and event participation and individuals’ controlled or autonomous motivation. Specifically, organizational motivations are proposed to en...
Why people stereotype affects how they stereotype: the differential influence of comprehension goals and self-enhancement goals on stereotyping.

van den Bos, Arne; Stapel, Diederik A

2009-01-01

In four studies, the authors examined the hypothesis that the way people stereotype is determined by the motives that instigate it. Study 1 measured and demonstrated the effectiveness of a commonly used priming technique to manipulate comprehension and self-enhancement goals. Study 2 demonstrated that why people stereotype determines how they stereotype: When a comprehension goal was salient, positive as well as negative stereotypes were applied, whereas a salient self-enhancement goal led to the application of negative but not positive stereotypes. Study 3 replicated these effects with different stereotypes. Study 4 replicated these effects and gave more insight in the consequences of goal fulfillment on stereotyping. Results indicated the fulfillment of a salient self-enhancement or comprehension goal led to the reduction of stereotyping. These effects were goal specific: Fulfillment of a self-enhancement goal decreased enhancement-driven but not comprehension-driven stereotyping; fulfillment of a comprehension goal decreased comprehension-driven but not enhancement-driven stereotyping.

The purpose of this study was to develop a multi-disciplinary self-management intervention based on empowerment theory and to evaluate the effectiveness of the intervention for older adults with chronic illness. A randomized controlled trial design was used with 43 Korean older adults with chronic illness (Experimental group=22, Control group=21). The intervention consisted of two phases: (1) 8-week multi-disciplinary, team guided, group-based health education, exercise session, and individual empowerment counseling, (2) 16-week self-help group activities including weekly exercise and group discussion to maintain acquired self-management skills and problem-solving skills. Baseline, 8-week, and 24-week assessments measured health empowerment, exercise self-efficacy, physical activity, and physical function. Health empowerment, physical activity, and physical function in the experimental group increased significantly compared to the control group over time. Exercise self-efficacy significantly increased in experimental group over time but there was no significant difference between the two groups. The self-management program based on empowerment theory improved health empowerment, physical activity, and physical function in older adults. The study finding suggests that a health empowerment strategy may be an effective approach for older adults with multiple chronic illnesses in terms of achieving a sense of control over their chronic illness and actively engaging self-management.

Increasing physical activity is an important public-health goal worldwide, but there are few published mediation analyses of physical-activity interventions in low-to-middle-income countries like South Africa undergoing a health transition involving markedly increased mortality from non-communicable diseases. This article reports secondary analyses on the mediation of a theory-of-planned-behavior-based behavioral intervention that increased self-reported physical activity in a trial with 1181 men in Eastern Cape Province, South Africa. Twenty-two matched-pairs of neighborhoods were randomly selected. Within pairs, neighborhoods were randomized to a health-promotion intervention or an attention-matched control intervention with baseline, immediate-post, and 6- and 12-month post-intervention assessments. Theory-of-planned-behavior constructs measured immediately post-intervention were tested as potential mediators of the primary outcome, self-reported physical activity averaged over the 6- and 12-month post-intervention assessments, using a product-of-coefficients approach in a generalized-estimating-equations framework. Data were collected in 2007-2010. Attitude, subjective norm, self-efficacy, and intention were significant mediators of intervention-induced increases in self-reported physical activity. The descriptive norm, not affected by the intervention, was not a mediator, but predicted increased self-reported physical activity. The results suggest that interventions targeting theory-of-planned-behavior constructs may contribute to efforts to increase physical activity to reduce the burden of non-communicable diseases among South African men.

Item response theory analysis of the Pain Self-Efficacy Questionnaire.

Science.gov (United States)

Costa, Daniel S J; Asghari, Ali; Nicholas, Michael K

2017-01-01

The Pain Self-Efficacy Questionnaire (PSEQ) is a 10-item instrument designed to assess the extent to which a person in pain believes s/he is able to accomplish various activities despite their pain. There is strong evidence for the validity and reliability of both the full-length PSEQ and a 2-item version. The purpose of this study is to further examine the properties of the PSEQ using an item response theory (IRT) approach. We used the two-parameter graded response model to examine the category probability curves, and location and discrimination parameters of the 10 PSEQ items. In item response theory, responses to a set of items are assumed to be probabilistically determined by a latent (unobserved) variable. In the graded-response model specifically, item response threshold (the value of the latent variable for which adjacent response categories are equally likely) and discrimination parameters are estimated for each item. Participants were 1511 mixed, chronic pain patients attending for initial assessment at a tertiary pain management centre. All items except item 7 ('I can cope with my pain without medication') performed well in IRT analysis, and the category probability curves suggested that participants used the 7-point response scale consistently. Items 6 ('I can still do many of the things I enjoy doing, such as hobbies or leisure activity, despite pain'), 8 ('I can still accomplish most of my goals in life, despite the pain') and 9 ('I can live a normal lifestyle, despite the pain') captured higher levels of the latent variable with greater precision. The results from this IRT analysis add to the body of evidence based on classical test theory illustrating the strong psychometric properties of the PSEQ. Despite the relatively poor performance of Item 7, its clinical utility warrants its retention in the questionnaire. The strong psychometric properties of the PSEQ support its use as an effective tool for assessing self-efficacy in people with pain
Theory of third-harmonic generation using Bessel beams, and self-phase-matching

International Nuclear Information System (INIS)

Tewari, S.P.; Huang, H.; Boyd, R.W.

1996-01-01

Taking Bessel beams (J 0 beam) as a representation of a conical beam, and a slowly varying envelope approximation (SVEA) we obtain the results for the theory of third-harmonic generation from an atomic medium. We demonstrate how the phenomenon of self-phase-matching is contained in the transverse-phase-matching integral of the theory. A method to calculate the transverse-phase-matching integral containing four Bessel functions is described which avoids the computer calculations of the Bessel functions. In order to consolidate the SVEA result an alternate method is used to obtain the exact result for the third-harmonic generation. The conditions are identified in which the exact result goes over to the result of the SVEA. The theory for multiple Bessel beams is also discussed which has been shown to be the source of the wide width of the efficiency curve of the third-harmonic generation observed in experiments. copyright 1996 The American Physical Society
Universal self-similar dynamics of relativistic and nonrelativistic field theories near nonthermal fixed points

Piñeiro Orioli, Asier; Boguslavski, Kirill; Berges, Jürgen

2015-07-01

We investigate universal behavior of isolated many-body systems far from equilibrium, which is relevant for a wide range of applications from ultracold quantum gases to high-energy particle physics. The universality is based on the existence of nonthermal fixed points, which represent nonequilibrium attractor solutions with self-similar scaling behavior. The corresponding dynamic universality classes turn out to be remarkably large, encompassing both relativistic as well as nonrelativistic quantum and classical systems. For the examples of nonrelativistic (Gross-Pitaevskii) and relativistic scalar field theory with quartic self-interactions, we demonstrate that infrared scaling exponents as well as scaling functions agree. We perform two independent nonperturbative calculations, first by using classical-statistical lattice simulation techniques and second by applying a vertex-resummed kinetic theory. The latter extends kinetic descriptions to the nonperturbative regime of overoccupied modes. Our results open new perspectives to learn from experiments with cold atoms aspects about the dynamics during the early stages of our universe.
Temperature dependent empirical pseudopotential theory for self-assembled quantum dots.

Wang, Jianping; Gong, Ming; Guo, Guang-Can; He, Lixin

2012-11-28

We develop a temperature dependent empirical pseudopotential theory to study the electronic and optical properties of self-assembled quantum dots (QDs) at finite temperature. The theory takes the effects of both lattice expansion and lattice vibration into account. We apply the theory to InAs/GaAs QDs. For the unstrained InAs/GaAs heterostructure, the conduction band offset increases whereas the valence band offset decreases with increasing temperature, and there is a type-I to type-II transition at approximately 135 K. Yet, for InAs/GaAs QDs, the holes are still localized in the QDs even at room temperature, because the large lattice mismatch between InAs and GaAs greatly enhances the valence band offset. The single-particle energy levels in the QDs show a strong temperature dependence due to the change of confinement potentials. Because of the changes of the band offsets, the electron wavefunctions confined in QDs increase by about 1-5%, whereas the hole wavefunctions decrease by about 30-40% when the temperature increases from 0 to 300 K. The calculated recombination energies of excitons, biexcitons and charged excitons show red shifts with increasing temperature which are in excellent agreement with available experimental data.
The lssue of Guilt in Oedipus and Joseph K.

Directory of Open Access Journals (Sweden)

Janez Vrečko

2002-07-01

Full Text Available This essay addresses hamartia in Oedipus and Joseph K., originally guilt without sin later turned in to guilt of sin, as well as freedom and fate, death and redemption. The tragedy Oedipus the King starts with the plague in Thebes, while The Trial starts with the arrest of Joseph K., both events leading to the source of »misfortune«; since the source of misfortune is external, the two protagonists are guilty without committing a crime. In both works Aristotle's concept of hamartia is understood as an objective »tragic flaw« as well as a subjective decision taken by the hero. Since »guiltiness invites judgment«, both Oedipus and Joseph K. choose to flee in a »Wrong direction«, which leads to the fulfilment of the prophecy and to a verdict respectively. They misunderstand the objective hamartia and transform their guilt without sin in to the guilt of sin. But Oedipus' uncovering of his own past once the prophecy is fulfilled leads him to a theophanic death, while Joseph's recognition that his life has come to ruin leads to a bestial death. Iocasta and several female characters in The Trial attempt to thrust both men back in to the arena of objective hamartia, to restore them to the state of guilt without crime, but they fail. They do succeed, however, in leading the heroes to anagnorisis. This recognition enables Oedipus to evince his sense of responsibility by carrying out his self-punishment. Joseph's recognition, by contrast, includes neither responsibility nor self-punishment. The scene with Titorelli shows that Joseph's trial can only take place between two extremes -justice and manhunt - and as such it has parallels with the Chorus song following the scene with Oedipus and Teiresias. Moreover, it has a connection with the chapter taking place in the Cathedral, since the protagonists of each scene are identified at this point and their destinies linked to their names. On another level this scene reveals a similarity between the Sphinx

Dying for the group: Towards a general theory of extreme self-sacrifice.

Science.gov (United States)

Whitehouse, Harvey

2018-02-07

Whether upheld as heroic or reviled as terrorism, throughout history people have been willing to lay down their lives for the sake of their groups. Why? Previous theories of extreme self-sacrifice have highlighted a range of seemingly disparate factors such as collective identity, outgroup hostility, and kin psychology. This paper attempts to integrate many of these factors into a single overarching theory based on several decades of collaborative research with a range of special populations, from tribes in Papua New Guinea to Libyan insurgents, and from Muslim fundamentalists in Indonesia to Brazilian football hooligans. These studies suggest that extreme self-sacrifice is motivated by 'identity fusion', a visceral sense of oneness with the group resulting from intense collective experiences (e.g. painful rituals or the horrors of frontline combat) or from perceptions of shared biology. In ancient foraging societies, fusion would have enabled warlike bands to stand united despite strong temptations to scatter and flee. The fusion mechanism has often been exploited in cultural rituals, not only by tribal societies but also in specialized cells embedded in armies, cults, and terrorist organizations. With the rise of social complexity and the spread of states and empires, fusion has also been extended to much larger groups, including doctrinal religions, ethnicities, and ideological movements. Explaining extreme self-sacrifice is not only a scientific priority but also a practical challenge as we seek a collective response to suicide terrorism and other extreme expressions of outgroup hostility that continue to bedevil humanity today.
Contributions of metacognitive and self-regulated learning theories to investigations of calibration of comprehension

Directory of Open Access Journals (Sweden)

Stephanie Stolp

2009-10-01

Full Text Available In this paper we examine the contributions of metacognitive and self-regulated learning theories to research on students' calibration of comprehension. Historically, cognitive psychologists have studied calibration of comprehension within a purely metacognitive framework, with an emphasis on the role of text and task factors but little consideration of factors of self. There has been a recent trend, however, towards incorporating a social cognitive perspective to the study of calibration of comprehension, with factors of self such as motivation and affect being examined more often. Among the factors of self that have been examined, self-efficacy has played a major role as it may be all but impossible to disentangle its influence on students' calibration of comprehension. Other variables of self that have been examined include ability, familiarity, ego and goal-orientation, goal setting, personality traits and susceptibility to social and cultural influences. Broadening the context in which calibration of comprehension is assessed allows a more complete examination of the rich set of interrelated processes that affect students' performance.

The affective profiles model distinguishes between individuals who are self-fulfilling (high positive affect, low negative affect), high affective (high positive affect, high negative affect), low affective (low positive affect, low negative affect), and self-destructive (low positive affect, high negative affect). The literature shows that the affective profiles model has been used with Swedish people in particular in order to determine differences among profiles in relation to life satisfaction, psychological well-being, self-esteem, and optimism. The present research investigated these differences in Italian high school students. Two studies were conducted: the first with 156 Italian high school students and the second with 148 Italian high school students. The first study analyzed differences among affective profiles with regard to life satisfaction and psychological well-being while the second study analyzed differences among affective profiles with regard to self-esteem and optimism. In the first study, the Positive and Negative Affect Schedule (PANAS), the Satisfaction with Life Scale, and the Meaningful Life Measure were administered to the participants. In the second study, the PANAS, the Self-Esteem Scale, the Life Orientation Test-revised were administered to the participants. The results of the first study showed that, with respect to the other profiles, the self-fulfilling participants had greater life satisfaction and psychological well-being. The results of the second study showed that, with respect to the other profiles, the self-fulfilling participants had higher self-esteem and optimism. These results revealed differences among affective profiles regarding life satisfaction, psychological well-being, self-esteem, and optimism in the Italian context as well thereby offering new possibilities for cross-cultural research and for enhancing self-fulfilling profiles.

Map Theory fulfills Church's original aim of lambda calculus. Map Theory is suited for reasoning about...... classical mathematics as well as computer programs. Furthermore, Map Theory is suited for eliminating the barrier between classical mathematics and computer science rather than just supporting the two fields side by side. Map Theory axiomatizes a universe of “maps”, some of which are “wellfounded......”. The class of wellfounded maps in Map Theory corresponds to the universe of sets in ZFC. The first axiomatization MT 0 of Map Theory had axioms which populated the class of wellfounded maps, much like the power set axiom along with others populate the universe of ZFC.

The theory of planned behaviour: self-identity, social identity and group norms.

Terry, D J; Hogg, M A; White, K M

1999-09-01

The aim of the present study was to examine further the role that self-identity plays in the theory of planned behaviour and, more specifically, to: (1) examine the combined effects of self-identity and social identity constructs on intention and behaviour, and (2) examine the effects of self-identity as a function of past experience of performing the behaviour. The study was concerned with the prediction of intention to engage in household recycling and reported recycling behaviour. A sample of 143 community residents participated in the study. It was prospective in design: measures of the predictors and intention were obtained at the first wave of data collection, whereas behaviour was assessed two weeks later. Self-identity significantly predicted behavioural intention, a relationship that was not dependent on the extent to which the behaviour had been performed in the past. As expected, there was also evidence that the perceived norm of a behaviourally relevant reference group was related to behavioural intention, but only for participants who identified strongly with the group, whereas the relationship between perceived behavioural control (a personal factor) and intention was strongest for low identifiers.

To test a hypothesized model that examines the relationship between selected basic conditioning factors, self-care agency, and self-care behaviors among adolescent girls with dysmenorrhea using Orem's self-care deficit nursing theory as a framework. This was a predictive correlational study conducted with a total of 531 secondary school girls. Self-care agency, self-care behaviors, and 11 variables that have been theoretically or empirically justified in previous studies as relevant to basic conditioning factors were selected and collected by means of structured questionnaires. Path analyses were performed to test the hypothesized linkages among variables. Path analysis revealed that age and received menstrual education had both direct and indirect effects through self-care agency on self-care behaviors. Mother's and father's educational level, pain intensity, and self-medication used when experiencing dysmenorrhea only affected the self-care behaviors directly. This is the first study that provided information about the relationship between basic conditioning factors, self-care agency, and self-care behaviors among adolescent girls with dysmenorrhea. Knowledge of the factors influencing self-care behaviors in these adolescent girls will assist healthcare professionals in developing effective interventions to promote self-care and ameliorate the adverse impact of this condition. Interventional strategies that aim at promoting self-care behaviors among adolescent girls with dysmenorrhea should strengthen girls' self-care agency and should target those with a younger age, higher pain intensity, mother with a higher educational level, father with a lower educational level, and those who do not take self-medication for dysmenorrhea. © 2015 Sigma Theta Tau International.

Self-determination theory is potentially useful for understanding reasons why individuals with mental illness do or do not engage in psychiatric treatment. The current study examined the psychometric properties of three questionnaires based on self-determination theory-The Treatment Entry Questionnaire (TEQ), Health Care Climate Questionnaire (HCCQ), and the Short Motivation Feedback List (SMFL)-in a sample of 348 Dutch adult outpatients with primary diagnoses of mood, anxiety, psychotic, and personality disorders. Structural equation modeling showed that the empirical factor structures of the TEQ and SMFL were adequately represented by a model with three intercorrelated factors. These were interpreted as identified, introjected, and external motivation. The reliabilities of the Dutch TEQ, HCCQ, and SMFL were found to be acceptable but can be improved on; congeneric estimates ranged from 0.66 to 0.94 depending on the measure and patient subsample. Preliminary support for the construct validities of the questionnaires was found in the form of theoretically expected associations with other scales, including therapist-rated motivation and treatment engagement and with legally mandated treatment. Additionally, the study provides insights into the relations between measures of motivation based on self-determination theory, the transtheoretical model and the integral model of treatment motivation in psychiatric outpatients with severe mental illness. © The Author(s) 2013.

2016-03-01

Non-suicidal self-injury (NSSI) is a public health concern that affects young adults at alarming rates. The present study examines the role of satisfaction of self-determination theory's three basic needs for autonomy, competence, and relatedness in young adults' NSSI engagement. University students who reported ever having engaged in NSSI (n = 40, 85 % female; Mage = 20.10, SD = 1.66) reported significantly lower levels of the satisfaction of all three needs, as well as more difficulties with all aspects of emotion regulation (non-acceptance of emotional responses, difficulty engaging in goal directed behavior, impulse control, lack of emotional awareness, limited access to regulation strategies, lack of emotional clarity), compared to students with no history of NSSI (n = 46, 91 % female; Mage = 19.79, SD = 1.37). Results of a logistic regression analysis revealed that need satisfaction added to the prediction of NSSI group membership after controlling for the effects of emotion regulation. Satisfaction of the need for competence and limited access to emotion regulation strategies accounted for significant variance in NSSI in the final model. The findings suggest that self-determination theory may be a useful framework under which to conceptualize NSSI and that the need for competence may be particularly salient for University students.
The Plumber’s Nightmare Phase in Diblock Copolymer/Homopolymer Blends. A Self-Consistent Field Theory Study.

KAUST Repository

Martinez-Veracoechea, Francisco J.

2009-11-24

Using self-consistent field theory, the Plumber\\'s Nightmare and the double diamond phases are predicted to be stable in a finite region of phase diagrams for blends of AB diblock copolymer (DBC) and A-component homopolymer. To the best of our knowledge, this is the first time that the P phase has been predicted to be stable using self-consistent field theory. The stabilization is achieved by tuning the composition or conformational asymmetry of the DBC chain, and the architecture or length of the homopolymer. The basic features of the phase diagrams are the same in all cases studied, suggesting a general type of behavior for these systems. Finally, it is noted that the homopolymer length should be a convenient variable to stabilize bicontinuous phases in experiments. © 2009 American Chemical Society.

This study tested an integrated model of the psychosocial determinants of alcohol-related behaviour among company employees from four nations. A motivational sequence was proposed in which motivational orientations from self-determination theory influenced intentions to consume alcohol within guideline limits and alcohol-related behaviour via the mediation of the theory of planned behaviour variables of attitude, subjective norms, and perceived behavioural control (PBC). A three-wave prospective design using self-reported psychological and behavioural measures. Company employees (N= 486, males = 225, females = 261; M age = 30.41, SD= 8.31) from four nations (Estonia, Finland, Sweden, and UK) completed measures of autonomous and controlled motivation from self-determination theory, attitudes, subjective norms, PBC, intentions from the theory of planned behaviour, and self-reported measures of past alcohol consumption and binge-drinking occasions at the first time point (time 1). Follow-up psychological and behavioural measures were taken one month later (time 2) and follow-up behavioural measures taken a further 2 months later (time 3). Path analyses supported the motivational sequence with identified regulation (time 1), predicting intentions (time 1), and alcohol units consumed (time 2). The effects were indirect via the mediation of attitudes and PBC (time 1). A similar pattern of effects was found for the effect of time 2 psychological variables on time 3 units of alcohol consumed. There was little support for the effects of the psychological variables on binge-drinking behaviour. Findings provide new information on the psychosocial determinants of alcohol behaviour in company employees and the processes involved. Results may provide impetus for the development of interventions to reduce alcohol consumption. ©2011 The British Psychological Society.

Some women with depressive disorders experience severe premenstrual symptoms. However, there have been few studies in which premenstrual symptoms in women suffering from depressive disorders were assessed. In this study, we aimed to investigate premenstrual symptoms in women with depressive disorders using the premenstrual dysphoric disorder (PMDD) scale. We administered questionnaires to 65 Japanese female outpatients who had been diagnosed with a major depressive disorder or dysthymic disorder and to 303 healthy women as control subjects. The questionnaire consisted of items on demographics and the PMDD scale, which was modified from the premenstrual symptoms screening tool (PSST) developed by Steiner et al. (Arch Womens Ment Health 2003, 6:203-209). Twenty-eight women (43.1%) with depressive disorder fulfilled certain items of the PMDD scale. These women are considered to have coexisting PMDD and a depressive disorder, or to have premenstrual exacerbation (PME) of a depressive disorder. On the other hand, 18 women (5.9%) in the control group were diagnosed as having PMDD. The depressive disorder group who fulfilled the PMDD criteria had more knowledge of the term premenstrual syndrome (PMS) and took more actions to attenuate premenstrual symptoms than the control group with PMDD. Our findings demonstrated that the occurrence of severe premenstrual symptoms is much higher in women with depressive disorders than in healthy subjects. This is partially due to this group containing women with PME, but mainly due to it containing women with PMDD. The higher percentage of PMDD suggests similarity between PMDD and other depressive disorders. Furthermore, educating healthy Japanese women and women with depressive disorders about premenstrual symptoms and evidence-based treatment for them is necessary.

A novel group of experiments has shown that single 10-micrometer-radius-scale laser spot is not able to produce the 90 deg side emitted three half harmonic efficiently in a preformed laser plasmas. However, with the help of one or two accessory laser spots with the size similar to the main one, the side emitted three half can easily built up when some position and angle conditions for the accessory spots are fulfilled. The origin of these phenomena have been analyzed in terms of the two plasmon decay theory and dynamic self-focusing model

Using self-efficacy theory to develop interventions that help older people overcome psychological barriers to physical activity: a discussion paper.

Lee, Ling-Ling; Arthur, Antony; Avis, Mark

2008-11-01

Only a fifth of older people undertake a level of physical activity sufficient to lead to health benefit. Misconceptions about the ageing process and beliefs about the costs and benefits of exercise in late life may result in unnecessary self-imposed activity restriction. Thus, adhering to a physical activity can be difficult particularly when the benefits of exercise are often not immediate. Many of the barriers to engaging in physical activity among older people are attitudinal. It is therefore important to take account of the non-physical aspects of physical activity intervention programmes, such as increasing confidence. Self-efficacy is a widely applied theory used to understand health behaviour and facilitate behavioural modification, such as the increase of physical activity. This paper aims to examine the ways in which self-efficacy theory might be used in intervention programmes designed to overcome psychological barriers for increasing physical activity among older people. A number of studies have demonstrated that exercise self-efficacy is strongly associated with the amount of physical activity undertaken. Evidence from some trials supports the view that incorporating the theory of self-efficacy into the design of a physical activity intervention is beneficial. Physical activity interventions aimed at improving the self perception of exercise self-efficacy can have positive effects on confidence and the ability to initiate and maintain physical activity behaviour. There are a number of ways for nurses to facilitate older people to draw on the four information sources of self-efficacy: performance accomplishments, vicarious learning, verbal encouragement, and physiological and affective states. Research challenges that future studies need to address include the generalisability of exercise setting, the role of age as an effect modifier, and the need for more explicit reporting of how self-efficacy is operationalised in interventions.
The social biofeedback theory of parental affect-mirroring: the development of emotional self-awareness and self-control in infancy.

Science.gov (United States)

Gergely, G; Watson, J S

1996-12-01

The authors present a new theory of parental affect-mirroring and its role in the development of emotional self-awareness and control in infancy. It is proposed that infants first become sensitised to their categorical emotion-states through a natural social biofeedback process provided by the parent's 'marked' reflections of the baby's emotion displays during affect-regulative interactions. They argue that this sensitisation process is mediated (similarly to that of adult biofeedback training) by the mechanism of contingency-detection and maximising. Apart from sensitisation, affect-mirroring serves three further developmental functions: (1) it contributes to the infant's state-regulation; (2) it leads to the establishment of secondary representations that become associated with the infant's primary procedural affect-states providing the cognitive means for accessing and attributing emotions to the self; (3) it results in the development of a generalised communicative code of "marked' expressions characterised by the representational functions of referential decoupling, anchoring and suspension of realistic consequences. They consider the clinical implications of our theory, relating it to current psychodynamic approaches to the functions of parental affect-mirroring. Using their model they identify various types of deviant mirroring styles and speculate about their developmental consequences. Finally, they discuss what role their social biofeedback model may play as a mediating mechanism in the therapeutic process.
Firm Size, a Self-Organized Critical Phenomenon: Evidence from the Dynamical Systems Theory

Science.gov (United States)

Chandra, Akhilesh

This research draws upon a recent innovation in the dynamical systems literature called the theory of self -organized criticality (SOC) (Bak, Tang, and Wiesenfeld 1988) to develop a computational model of a firm's size by relating its internal and the external sub-systems. As a holistic paradigm, the theory of SOC implies that a firm as a composite system of many degrees of freedom naturally evolves to a critical state in which a minor event starts a chain reaction that can affect either a part or the system as a whole. Thus, the global features of a firm cannot be understood by analyzing its individual parts separately. The causal framework builds upon a constant capital resource to support a volume of production at the existing level of efficiency. The critical size is defined as the production level at which the average product of a firm's factors of production attains its maximum value. The non -linearity is inferred by a change in the nature of relations at the border of criticality, between size and the two performance variables, viz., the operating efficiency and the financial efficiency. The effect of breaching the critical size is examined on the stock price reactions. Consistent with the theory of SOC, it is hypothesized that the temporal response of a firm breaching the level of critical size should behave as a flicker noise (1/f) process. The flicker noise is characterized by correlations extended over a wide range of time scales, indicating some sort of cooperative effect among a firm's degrees of freedom. It is further hypothesized that a firm's size evolves to a spatial structure with scale-invariant, self-similar (fractal) properties. The system is said to be self-organized inasmuch as it naturally evolves to the state of criticality without any detailed specifications of the initial conditions. In this respect, the critical state is an attractor of the firm's dynamics. Another set of hypotheses examines the relations between the size and the
Precision calculations for h → WW/ZZ → 4 fermions in the Two-Higgs-Doublet Model with Prophecy4f

We have calculated the next-to-leading-order electroweak and QCD corrections to the decay processes h → WW/ZZ → 4 fermions of the light CP-even Higgs boson h of various types of Two-Higgs-Doublet Models (Types I and II, "lepton-specific" and "flipped" models). The input parameters are defined in four different renormalization schemes, where parameters that are not directly accessible by experiments are defined in the \\overline{MS} scheme. Numerical results are presented for the corrections to partial decay widths for various benchmark scenarios previously motivated in the literature, where we investigate the dependence on the \\overline{MS} renormalization scale and on the choice of the renormalization scheme in detail. We find that it is crucial to be precise with these issues in parameter analyses, since parameter conversions between different schemes can involve sizeable or large corrections, especially in scenarios that are close to experimental exclusion limits or theoretical bounds. It even turns out that some renormalization schemes are not applicable in specific regions of parameter space. Our investigation of differential distributions shows that corrections beyond the Standard Model are mostly constant offsets induced by the mixing between the light and heavy CP-even Higgs bosons, so that differential analyses of h→4 f decay observables do not help to identify Two-Higgs-Doublet Models. Moreover, the decay widths do not significantly depend on the specific type of those models. The calculations are implemented in the public Monte Carlo generator Prophecy4f and ready for application.
Dialogical Self Theory and the increasing multiplicity of I-positions in a globalizing society: an introduction.

Science.gov (United States)

Hermans, Hubert J M

2012-01-01

Dialogical Self Theory is a recent development in the social sciences, based on a conception of the self as a society of mind. In this conception, the self is considered as extended to significant others in the environment, who populate the self as a dynamic multiplicity of I-positions between which dialogical or monological relationships may emerge. While from a spatial perspective the self is engaged in a process of positioning and counterpositioning in a globalizing society, from a temporal point of view the self is part of a process of positioning and repositioning in collective history and personal development. Some phenomena that are necessary for the understanding of the dialogical self are discussed: dominance and social power, the processes of globalization and localization, the experience of uncertainty and possible reactions to uncertainty in a globalizing world. Finally, the different contributions of this special issue are placed in the context of the presented conceptual framework. Copyright © 2012 Wiley Periodicals, Inc., A Wiley Company.
The self-perceived survival ability and reproductive fitness (SPFit) theory of substance use disorders.

Science.gov (United States)

Newlin, David B

2002-04-01

A new theory of substance use disorders is proposed-the SPFit theory-that is based on evolutionary biology and adaptive systems. Self-perceived survival ability and reproductive fitness (SPFit) is proposed as a human psychobiological construct that prioritizes and organizes (i.e. motivates) behavior, but is highly vulnerable to temporary, artificial activation by drugs of abuse. Autoshaping/sign-tracking/feature positive phenomena are proposed to underlie the development of craving and expectations about drugs as the individual learns that abused drugs will easily and reliably inflate SPFit. The cortico-mesolimbic dopamine system and its modulating interconnections are viewed as the biological substrate of SPFit; it is proposed to be a survival and reproductive motivation system rather than a reward center or reward pathway. Finally, the concept of modularity of mind is applied to the SPFit construct. Although considerable empirical data are consistent with the theory, new research is needed to test specific hypotheses derived from SPFit theory.

Full Text Available The affective profiles model distinguishes between individuals who are self-fulfilling (high positive affect, low negative affect, high affective (high positive affect, high negative affect, low affective (low positive affect, low negative affect, and self-destructive (low positive affect, high negative affect. The literature shows that the affective profiles model has been used with Swedish people in particular in order to determine differences among profiles in relation to life satisfaction, psychological well-being, self-esteem, and optimism. The present research investigated these differences in Italian high school students. Two studies were conducted: the first with 156 Italian high school students and the second with 148 Italian high school students. The first study analyzed differences among affective profiles with regard to life satisfaction and psychological well-being while the second study analyzed differences among affective profiles with regard to self-esteem and optimism. In the first study, the Positive and Negative Affect Schedule (PANAS, the Satisfaction With Life Scale (SWLS, and the Meaningful Life Measure (MLM were administered to the participants. In the second study, the Positive and Negative Affect Schedule (PANAS, the Self-Esteem Scale (SES, the Life Orientation Test - revised (LOT-r were administered to the participants. The results of the first study showed that, with respect to the other profiles, the self-fulfilling participants had greater life satisfaction and psychological well-being. The results of the second study showed that, with respect to the other profiles, the self-fulfilling participants had higher self-esteem and optimism. These results revealed differences among affective profiles regarding life satisfaction, psychological well-being, self-esteem, and optimism in the Italian context as well thereby offering new possibilities for cross-cultural research and for enhancing self-fulfilling profiles.

It is demonstrated by three-dimensional simulations for resistive magnetohydrodynamic (MHD) plasmas with both 'spatially nonuniform resistivity η' and 'uniformη' that the attractor of the dissipative structure in the resistive MHD plasmas is given by ∇ x (ηj) = (α/2)B which is derived from a novel self-organization theory based on the minimum dissipation rate profile. It is shown by the simulations that the attractor is reduced to ∇ x B = λB in the special case with the 'uniformη' and no pressure gradient. (author)

Patient education in connection with hip replacement is intended to prepare patients for surgery, discharge and postoperative recovery. Patients experience symptoms and emotions due to disease or upcoming surgery which can affect how their knowledge expectations are fulfilled. To describe the differences between received and expected knowledge in patients undergoing elective hip replacement in three Nordic countries, and to analyse how these differences are related to patients' characteristics, preoperative symptoms and emotions. A descriptive, prospective survey with two data collection points; before admission and at hospital discharge after surgery. Two Finnish, three Icelandic and two Swedish hospitals. The population consisted of patients on a waiting list for hip replacement. Of the consecutively included patients, 320 answered questionnaires both before admission and at discharge and were included in the study. The mean age of the patients was 64 years, and 55% were women. Structured questionnaires were used; the knowledge expectations of hospital patients scale and self-reported scales for symptoms and emotions before admission and received knowledge of hospital patients scale at discharge. Fulfilment of knowledge expectation was assessed by calculating the difference between received and expected knowledge with a paired sample t-test. A multiple stepwise regression model was used to explain the variance of fulfilled knowledge expectations. Patients expected more knowledge than they received (p<0.001) and 77% of them had unfulfilled knowledge expectations. Patients with a higher level of education were more likely to have unfulfilled knowledge expectations. A higher level of education was also related to a greater difference between received and expected knowledge. The difference was more correlated with patients' emotions than their symptoms. A depressive state was the major predictor of the variance in the difference between received and expected
