    The Theory of Planned Behavior (TpB) is useful to direct nursing research aimed at behavior change. As proposed in the TpB, individuals' attitudes, perceived norms, and perceived behavior control predict their intentions to perform a behavior and subsequently predict their actual performance of the behavior. Our purpose was to apply Fishbein and Ajzen's guidelines to begin development of a valid and reliable instrument for pediatric nurses' attitudes, perceived norms, perceived behavior control, and intentions to administer PRN opioid analgesics when hospitalized children self-report moderate to severe pain. Following Fishbein and Ajzen's directions, we were able to define the behavior of interest and specify the research population, formulate items for direct measures, elicit salient beliefs shared by our target population and formulate items for indirect measures, and prepare and test our questionnaire. For the pilot testing of internal consistency of measurement items, Cronbach alphas were between 0.60 and 0.90 for all constructs. Test-retest reliability correlations ranged from 0.63 to 0.90. Following Fishbein and Ajzen's guidelines was a feasible and organized approach for instrument development. In these early stages, we demonstrated good reliability for most subscales, showing promise for the instrument and its use in pain management research. Better understanding of the TpB constructs will facilitate the development of interventions targeted toward nurses' attitudes, perceived norms, and/or perceived behavior control to ultimately improve their pain behaviors toward reducing pain for vulnerable children.

    A better understanding of women's perceptions of weight gain and related behaviors during pregnancy is necessary to inform behavioral interventions. We used the Theory of Planned Behavior (TPB) to examine pregnant women's perceptions and intentions toward weight gain, physical activity (PA), and nutrition using a mixed methods study design. Women between 20 and 30 weeks gestation (n = 189) were recruited to complete an Internet-based survey. Salient beliefs toward weight gain, PA, and nutrition were captured through open-ended responses and content analyzed into themes. TPB constructs (attitude, subjective norm, perceived behavioral control, intentions) were examined using Pearson correlations and hierarchical linear regression models. Salient beliefs were consistent with the existing literature in non-pregnant populations, with the addition of many pregnancy-specific beliefs. TPB constructs accounted for 23-39 % of the variance in weight gain, PA, and nutrition intentions, and made varying contributions across outcomes. The TPB is a useful framework for examining women's weight-related intentions during pregnancy. Study implications for intervention development are discussed. PMID:26335313

  3. Exploring motivations to seek and undergo prosthodontic care: an empirical approach using the Theory of Planned Behavior construct.

    2014-01-01

    Motivations for seeking and undergoing prosthodontic care are poorly understood and are not often explored for clinical purposes when determining treatment need and understanding the factors related to the demand for health care and effective use. This article uses the Theory of Planned Behavior construct to identify factors related to the motivations of edentulous subjects to seek and undergo prosthodontic treatment. The conceptual framework of the Theory of Planned Behavior includes attitude toward behavior, an individual's positive or negative evaluation of self-performance of the particular behavior; the subjective norm, an individual's perception of social normative pressures or relevant others' beliefs that he or she should or should not perform such behavior; and perceived behavioral control, or an individual's perceived ease or difficulty in performing the particular behavior, determined by the total set of accessible control beliefs. These components mediate a subject's intention and behavior toward an object and may also explain health-related behaviors, providing strong predictions across a range of health behaviors. This study suggests categories for each component of the Theory of Planned Behavior, based on clinical evidence and practical reasoning. Attitudes toward behavior include perceived consequences of no treatment, perceived potential benefits and risks of treatment, dental anxiety, previous experiences, and interpersonal abilities of the health care providers. The subjective norm includes the opinions of relevant others, advertisement, professionally defined normative need, perceived professional skills, and technical quality of care. Perceived behavioral control includes subject's time, availability and opportunity, treatment costs, subject's perceived need, and accessibility to dental care. This conceptual model represents a theoretical multidimensional model that may help clinicians better understand the patient's treatment behaviors and

    The links between theory and construction management (CM), and for that matter construction economics (CE), are not strong (see de Valence 2011). This may be one of the reasons why they have not gained complete acceptance as academic disciplines and are not seen as distinct branches of economics and management respectively. Another reason may be that products and production (the focus of management and economic theories respectively) are not the same as projects and project management in gene...

  9. Architectural Theory: A Construction Site

    Directory of Open Access Journals (Sweden)

    Ákos Moravánszky

    2014-07-01

    Full Text Available Around 1968 we saw the birth of a new architectural theory as the conjunction of architectural history and politically engaged architectural criticism. Not the aesthetics of architecture, but architecture itself in its structural relations with social life became the focus of attention. As a result of this development, it is no longer possible to study architectural history without a critical reflection on the method of the study itself and without a grade of interdisciplinarity. Traditional methods of historiography and iconography have been replaced by new approaches configured by psychoanalysis, deconstruction, cultural studies etc. Appropriation has become the proof of criticality both in architectural theory and in design; however, the understanding of the concepts and methods of other disciplines is basically metaphorical. The problem for a school of architecture lies not in the ‘criticality’ of the kind of architectural theory we described as emerging from the spirit of 1968, but in its discursive nature. The disciplinary specificity of architecture resists a discursive approach, and architectural students frequently question the usefulness of theory which undermines the notion of the ‘project’, without articulating a constructive proposal. Projectivity does not seem to provide an answer; its claim of performativity lacks the program to regain its organising power over contributions from other specialised disciplines and practices. Theory should focus on the terms of our discipline, which are so close to our ‘core beliefs’ regarding architecture that we usually take their meaning for granted. It would be wrong to see this focus of theory as a withdrawal into the realm of language. Indeed, after a period of theory alienating architects and the general public, it could now create a rhetoric to influence our understanding of our environment, which is itself organised on the level of language. The requirement that theory should

  14. A critical review of constructal theory

    International Nuclear Information System (INIS)

    Constructal theory applied to the volume to point or point to volume flows aims to decrease global flow resistance by furnishing low resistive flow links in the flow field. Constructal theory expects to improve the flow performance by increasing the branching of the low resistive flow links. Fourteen different constructal theory applications involving tree shaped flow networks are reviewed with the purpose to check whether the increase in branching of tree shaped flow networks leads to increased flow performance or not? In other words, the review aims to answer the question; does the evolution model of constructal theory, increasing the branching of tree shaped flow networks through the sequence of constructal designs, improve the flow performance? The review shows that constructal theory will not necessarily improve the flow performance if the internal branching of the flow field is increased, in contrast, the performance will mostly be lowered if the internal branching of the flow field is increased

    2016-01-01

    This article explicates the theory of drive and describes the development and validation of two measures. A representative set of drive facets was derived from an extensive corpus of human attributes (Study 1). Operationalised using an International Personality Item Pool version (the Drive:IPIP), a three-factor model was extracted from the facets in two samples and confirmed on a third sample (Study 2). The multi-item IPIP measure showed congruence with a short form, based on single-item ratings of the facets, and both demonstrated cross-informant reliability. Evidence also supported the measures' convergent, discriminant, concurrent, and incremental validity (Study 3). Based on very promising findings, the authors hope to initiate a stream of research in what is argued to be a rather neglected niche of individual differences and non-cognitive assessment.

  3. Personality theory, abnormal psychology, and psychological measurement. A psychological behaviorism.

    Science.gov (United States)

    Staats, A W

    1993-01-01

    Behaviorism, because it has not had a theory of personality, has been separated from the rest of psychology, unable in large part to draw from or contribute to it. Traditional psychology has not had a theory of personality that says what personality is, how it comes about, or how it functions. An antagonism has resulted that weakens rather than complements each tradition. Psychological behaviorism presents a new type of theory of personality. Derived from experimentation, it is constructed from basic theories of emotion, language, and sensory-motor behavior. It says personality is composed of learned basic behavioral repertoires (BBRs) that affect behavior. Personality measurement instruments are analyzed in terms of the BBRs, beginning the behaviorization of this field and calling for much additional research. These multilevel developments are then basic in psychological behaviorism's theory of abnormal behavior and of clinical treatment. The approach opens many new avenues of empirical and theoretical work. PMID:8439278

  7. Conformal field theories, representations and lattice constructions

    International Nuclear Information System (INIS)

    An account is given of the structure and representations of chiral bosonic meromorphic conformal field theories (CFT's), and, in particular, the conditions under which such a CFT may be extended by a representation to form a new theory. This general approach is illustrated by considering the untwisted and Z2-twisted theories, H(Λ) and H(Λ) respectively, which may be constructed from a suitable even Euclidean lattice Λ. Similarly, one may construct lattices ΛC and LambdaC by analogous constructions from a doubly-even binary code C. In the case when C is self-dual, the corresponding lattices are also. Similarly, H(Λ) and H(Λ) are self-dual if and only if Λ is. We show that H(ΛC) has a natural triality structure, which induces an isomorphism H(ΛC)≡H(ΛC) and also a triality structure on H(ΛC). For C the Golay code, ΛC is the Leech lattice, and the triality on H(ΛC) is the symmetry which extends the natural action of (an extension of) Conway's group on this theory to the Monster, so setting triality and Frenkel, Lepowsky and Meurman's construction of the natural Monster module in a more general context. The results also serve to shed some light on the classification of self-dual CFT's. We find that of the 48 theories H(Λ) and H(Λ) with central charge 24 that there are 39 distinct ones, and further that all 9 coincidences are accounted for by the isomorphism detailed above, induced by the existence of a doubly-even self-dual binary code.

  10. Constructing acoustic timefronts using random matrix theory

    CERN Document Server

    Hegewisch, Katherine C

    2012-01-01

    In a recent letter [Europhys. Lett. {\\bf 97}, 34002 (2012)], random matrix theory is introduced for long-range acoustic propagation in the ocean. The theory is expressed in terms of unitary propagation matrices that represent the scattering between acoustic modes due to sound speed fluctuations induced by the ocean's internal waves. The scattering exhibits a power-law decay as a function of the differences in mode numbers thereby generating a power-law, banded, random unitary matrix ensemble. This work gives a more complete account of that approach and extends the methods to the construction of an ensemble of acoustic timefronts. The result is a very efficient method for studying the statistical properties of timefronts at various propagation ranges that agrees well with propagation based on the parabolic equation. It helps identify which information about the ocean environment survives in the timefronts and how to connect features of the data to the surviving environmental information. It also makes direct c...

  18. A quantitative evolutionary theory of adaptive behavior dynamics.

    Science.gov (United States)

    McDowell, J J

    2013-10-01

    The idea that behavior is selected by its consequences in a process analogous to organic evolution has been discussed for over 100 years. A recently proposed theory instantiates this idea by means of a genetic algorithm that operates on a population of potential behaviors. Behaviors in the population are represented by numbers in decimal integer (phenotypic) and binary bit string (genotypic) forms. One behavior from the population is emitted at random each time tick, after which a new population of potential behaviors is constructed by recombining parent behavior bit strings. If the emitted behavior produced a benefit to the organism, then parents are chosen on the basis of their phenotypic similarity to the emitted behavior; otherwise, they are chosen at random. After parent behavior recombination, the population is subjected to a small amount of mutation by flipping random bits in the population's bit strings. The behavior generated by this process of selection, reproduction, and mutation reaches equilibrium states that conform to every empirically valid equation of matching theory, exactly and without systematic error. These equations are known to describe the behavior of many vertebrate species, including humans, in a variety of experimental, naturalistic, natural, and social environments. The evolutionary theory also generates instantaneous dynamics and patterns of preference change in constantly changing environments that are consistent with the dynamics of live-organism behavior. These findings support the assertion that the world of behavior we observe and measure is generated by evolutionary dynamics. PMID:24219847

  2. The role of descriptive norm within the theory of planned behavior in predicting Korean Americans' exercise behavior.

    Science.gov (United States)

    Lee, Hyo

    2011-08-01

    There are few studies investigating psychosocial mechanisms in Korean Americans' exercise behavior. The present study tested the usefulness of the theory of planned behavior in predicting Korean American's exercise behavior and whether the descriptive norm (i.e., perceptions of what others do) improved the predictive validity of the theory of planned behavior. Using a retrospective design and self-report measures, web-survey responses from 198 Korean-American adults were analyzed using hierarchical regression analyses. The theory of planned behavior constructs accounted for 31% of exercise behavior and 43% of exercise intention. Intention and perceived behavioral control were significant predictors of exercise behavior. Although the descriptive norm did not augment the theory of planned behavior, all original constructs--attitude, injunctive norm (a narrow definition of subjective norm), and perceived behavioral control--statistically significantly predicted leisure-time physical activity intention. Future studies should consider random sampling, prospective design, and objective measures of physical activity. PMID:22049662

  6. Integrating multiple health behavior theories into program planning: the PER worksheet.

    Science.gov (United States)

    Langlois, Marietta A; Hallam, Jeffrey S

    2010-03-01

    The foundation of a logic model or any theory-based planning model is the identification of the behavioral antecedents and the relationship of these variables to the target behavior. Applying theoretical concepts to specific behaviors and populations is often challenging for practitioners and program planning students. The challenge comes from the abstract definition of theoretical constructs, the duplication of similar constructs in multiple theories, and the need to combine multiple theories. To simplify the planning process when utilizing logic models and health behavior theory, we recommend the use of the PER Worksheet. The PER Worksheet is a planning tool that provides layman-term prompts for identifying health behavior antecedents. It encompasses five common health behavior theories-health belief model, theory of planned behavior, social cognitive theory, an ecological perspective, and transtheoretical model. The PER Worksheet is organized into three columns: Predisposing, Enabling, and Reinforcing factors, terms of the PRECEDE/PROCEED model. PMID:18552278

    2007-01-01

    Since the development of the first intelligence test in the early 20th century, educational and psychological tests have become important measurement techniques to quantify human behavior. Focusing on this ubiquitous yet fruitful area of research, Statistical Test Theory for the Behavioral Sciences provides both a broad overview and a critical survey of assorted testing theories and models used in psychology, education, and other behavioral science fields. Following a logical progression from basic concepts to more advanced topics, the book first explains classical test theory, covering true score, measurement error, and reliability. It then presents generalizability theory, which provides a framework to deal with various aspects of test scores. In addition, the authors discuss the concept of validity in testing, offering a strategy for evidence-based validity. In the two chapters devoted to item response theory (IRT), the book explores item response models, such as the Rasch model, and applications, incl...

  13. String theory constructions and conformal invariance

    International Nuclear Information System (INIS)

    This paper reports that as is rather well known, string theories are regarded nowadays by theoretical physicists as a possible framework for the Theory of Everything, or more correctly, for a consistent unified quantum theory of all particles and all their interactions, including gravity. One of the many fascinating facets of these theories is that they could make a centuries old dream come true in a most unique way. Indeed, string theories could well provide the ultimate unification of Nature: the Universe and all that it contains being made of only one fundamental object, with dynamics so rich that it leads to this infinitely large variety of physical phenomena that we observe at all energy scales in our Universe. Moreover, the mathematical structures involved in these theories are so profound and beautiful that they bring together so far unrelated fields in pure mathematics, and have led to important developments in other fields of physics as well. All of physics and all of mathematics coming together in our understanding of the world: was that not the ultimate dream of the Ancient Greeks? But, what are string theories? In the first qualitative approach of this introduction, it may be useful to contrast these theories against the more familiar description of relativistic point-particles. When a single particle propagates freely in space-time, it describes a one- dimensional manifold: its world line. In a quantum description, we associate to this process a quantum amplitude: the Feynman propagator. It is also possible to describe interactions between such particles, by defining probability amplitudes for the splitting and joining of the corresponding world-lines (a priori, the number of particles involved in any such single interaction could be arbitrary but finite)

  14. On constructing purely affine theories with matter

    Cervantes-Cota, Jorge L.; Liebscher, D.-E.

    2016-08-01

    We explore ways to obtain the very existence of a space-time metric from an action principle that does not refer to it a priori. Although there are reasons to believe that only a non-local theory can viably achieve this goal, we investigate here local theories that start with Schrödinger's purely affine theory (Schrödinger in Space-time structure. Cambridge UP, Cambridge, 1950), where he gave reasons to set the metric proportional to the Ricci curvature aposteriori. When we leave the context of unified field theory, and we couple the non-gravitational matter using some weak equivalence principle, we can show that the propagation of shock waves does not define a lightcone when the purely affine theory is local and avoids the explicit use of the Ricci tensor in realizing the weak equivalence principle. When the Ricci tensor is substituted for the metric, the equations seem to have only a very limited set of solutions. This backs the conviction that viable purely affine theories have to be non-local.

    The large transverse momentum behavior of Compton scattering and Moeller scattering in Quantum Electrodynamics; and of elastic quark-quark scattering in Quantum Chromodynamics are examined in perturbation theory. The results strongly suggest that the large transverse momentum regime in gauge theories is governed by a differential equation of the Callan-Symanzik type with a suitable momentum dependent anomalous dimension term. An explicit solution for the quark-quark elastic scattering amplitude at large transverse momentum is given

    The Behavioral Portfolio Theory (BTP) developed by Shefrin and Statman (2000) considers a probability weighting function rather than the real probability distribution used in Markowitz’s Portfolio Theory (1952). The optimal portfolio of a BTP investor, which consists in a combination of bonds and lottery ticket, can differ from the perfectly diversified portfolio of Markowitz. We found that this particular form of portfolio is not due to the weighting function. In this article we explore the ...

  1. Optimal search behavior and classic foraging theory

    International Nuclear Information System (INIS)

    Random walk methods and diffusion theory pervaded ecological sciences as methods to analyze and describe animal movement. Consequently, statistical physics was mostly seen as a toolbox rather than as a conceptual framework that could contribute to theory on evolutionary biology and ecology. However, the existence of mechanistic relationships and feedbacks between behavioral processes and statistical patterns of movement suggests that, beyond movement quantification, statistical physics may prove to be an adequate framework to understand animal behavior across scales from an ecological and evolutionary perspective. Recently developed random search theory has served to critically re-evaluate classic ecological questions on animal foraging. For instance, during the last few years, there has been a growing debate on whether search behavior can include traits that improve success by optimizing random (stochastic) searches. Here, we stress the need to bring together the general encounter problem within foraging theory, as a mean for making progress in the biological understanding of random searching. By sketching the assumptions of optimal foraging theory (OFT) and by summarizing recent results on random search strategies, we pinpoint ways to extend classic OFT, and integrate the study of search strategies and its main results into the more general theory of optimal foraging.

  9. Construction of relativistic quantum theory: a progress report

    International Nuclear Information System (INIS)

    We construct the particulate states of quantum physics using a recursive computer program that incorporates non-determinism by means of locally arbitrary choices. Quantum numbers and coupling constants arise from the construction via the unique 4-level combinatorial hierarchy. The construction defines indivisible quantum events with the requisite supraluminal correlations, yet does not allow supraluminal communication. Measurement criteria incorporate c, h-bar and m/sub p/ or (not ''and'') G, connected to laboratory events via finite particle number scattering theory and the counter paradigm. The resulting theory is discrete throughout, contains no infinities, and, as far as we have developed it, is in agreement with quantum mechanical and cosmological fact

  10. Behavioral variability in an evolutionary theory of behavior dynamics.

    Science.gov (United States)

    Popa, Andrei; McDowell, J J

    2016-03-01

    McDowell's evolutionary theory of behavior dynamics (McDowell, 2004) instantiates populations of behaviors (abstractly represented by integers) that evolve under the selection pressure of the environment in the form of positive reinforcement. Each generation gives rise to the next via low-level Darwinian processes of selection, recombination, and mutation. The emergent patterns can be analyzed and compared to those produced by biological organisms. The purpose of this project was to explore the effects of high mutation rates on behavioral variability in environments that arranged different reinforcer rates and magnitudes. Behavioral variability increased with the rate of mutation. High reinforcer rates and magnitudes reduced these effects; low reinforcer rates and magnitudes augmented them. These results are in agreement with live-organism research on behavioral variability. Various combinations of mutation rates, reinforcer rates, and reinforcer magnitudes produced similar high-level outcomes (equifinality). These findings suggest that the independent variables that describe an experimental condition interact; that is, they do not influence behavior independently. These conclusions have implications for the interpretation of high levels of variability, mathematical undermatching, and the matching theory. The last part of the discussion centers on a potential biological counterpart for the rate of mutation, namely spontaneous fluctuations in the brain's default mode network. PMID:27002687

    Theory of mind refers to the abilities underlying the capacity to reason about one's own and others' mental states. This ability is critical for predicting and making sense of the actions of others, is essential for efficient communication, fosters social learning, and provides the foundation for empathic concern. Clearly, there is incredible value in fostering theory of mind. Unfortunately, despite being the focus of a wealth of research over the last 40 years relatively little is known about specific strategies for fostering social perspective taking abilities. We provide a discussion of the rationale for applying one specific strategy for fostering efficient theory of mind-that of engaging in "behavioral synchrony" (i.e., the act of keeping together in time with others). Culturally evolved collective rituals involving synchronous actions have long been held to act as social glue. Specifically, here we present how behavioral synchrony tunes our minds for reasoning about other minds in the process of fostering social coordination and cooperation, and propose that we can apply behavioral synchrony as a tool for enhancing theory of mind.

    Let H be a Hilbert space, A ∈ L(H), y ∈ R(A), and y R(A). We study the behavior of the distance square between y and A(BT), defined as a functional F(T), as the radius T of the ball BT of H tends to ∞. This problem is important in estimating the approximation error in learning theory. Our main result is to estimate the asymptotic behavior of F(T) without the compactness assumption on the operator A. We also consider the Peetre K-functional and its convergence rates.

  20. Tensor constructions of open string theories. I. Foundations

    International Nuclear Information System (INIS)

    The possible tensor constructions of open string theories are analyzed from first principles. To this end the algebraic framework of open string field theory is clarified, including the role of the homotopy associative A∞ algebra, the odd symplectic structure, cyclicity, star conjugation, and twist. It is also shown that two string theories are off-shell equivalent if the corresponding homotopy associative algebras are homotopy equivalent in a strict sense. It is demonstrated that a homotopy associative star algebra with a compatible even bilinear form can be attached to an open string theory. If this algebra does not have a space-time interpretation, positivity and the existence of a conserved ghost number require that its cohomology is at degree zero, and that it has the structure of a direct sum of full matrix algebras. The resulting string theory is shown to be physically equivalent to a string theory with a familiar open string gauge group. (orig.)

    Full Text Available Abstract Background To investigate the efficacy of the Theory of Planned Behavior (TPB to predict healthy eating behavior in a group of urban Native American youth. Methods Native American boys and girls (n = 139, ages 9–18 years old, were given a self-administered survey to assess eating behavior using the TBP constructs (intention, attitude, subjective norm, barriers, self-efficacy, and perceived behavioral control. Youth were also measured for height and weight and body mass index (BMI was calculated. Bivariate correlations and stepwise regression analyses of TBP model were performed with SPSS software. Results No association was found between intention and healthy eating behavior. However, independently healthy eating behavior was correlated with barriers (0.46, attitude (0.44, perceived behavioral control (0.35, and subjective norm (0.34. The most predictive barriers to eating healthy included the availability and taste of foods. Boys' eating behavior was most predicted by subjective norm, while girls' eating behavior was most predicted by barriers. Conclusion Lack of association between intention and healthy eating behavior suggests that factors other than intentions may drive healthy eating behaviors in urban Native American youth. Results indicate that programs promoting healthy eating to youth might focus on collaborating with families to make healthy foods more appealing to youth.

Then we present an analysis frame to expound the process, which includes the process of organization definition, the process of role definition, the process of organizational structure definition and the process of interaction protocol definition. Lastly, we discuss some issues associated with the processes of system design and implementation.

Our construction is applicable to the case of any classes giving the twisting, and agrees with the Chern character of bundle gerbe modules in the case of torsion classes.

    Full Text Available Background: People's behaviors and intentions about healthy behaviors depend on their beliefs, values, and knowledge about the issue. Various models of health education are used in deter-mining predictors of different healthy behaviors but their efficacy in cultural behaviors, such as water saving behaviors, are not studied. The study was conducted to explain water saving beha-viors in Yazd, Iran on the basis of Health Belief Model and Reasoned Action Theory. Methods: The cross-sectional study used random cluster sampling to recruit 200 heads of households to collect the data. The survey questionnaire was tested for its content validity and reliability. Analysis of data included descriptive statistics, simple correlation, hierarchical multiple regression. Results: Simple correlations between water saving behaviors and Reasoned Action Theory and Health Belief Model constructs were statistically significant. Health Belief Model and Reasoned Action Theory constructs explained 20.80% and 8.40% of the variances in water saving beha-viors, respectively. Perceived barriers were the strongest Predictor. Additionally, there was a sta-tistically positive correlation between water saving behaviors and intention. Conclusion: In designing interventions aimed at water waste prevention, barriers of water saving behaviors should be addressed first, followed by people's attitude towards water saving. Health Belief Model constructs, with the exception of perceived severity and benefits, is more powerful than is Reasoned Action Theory in predicting water saving behavior and may be used as a framework for educational interventions aimed at improving water saving behaviors.

    Full Text Available The main goal of this study was to create an instrument for assessing tendency towards superstition-related beliefs and behavior and validate it in real life situations. Superstition was considered and analyzed as an attitude toward specific objects of the superstition. In the first part of the study, a sample of superstitious beliefs and behaviors was collected, after which the former list was reduced to 44 descriptions, based on the average familiarity. A preliminary version of the instrument was administered to 266 participants. The factor analysis suggested a presence of one main factor and three highly correlated sub-factors. In the last part of the study, in order to validate the instrument through behavioral variables, the final version of the instrument was administered to a different sample and subjects were put in two situations that challenged their potential superstitious behavior (passing below or going around a ladder in a computer laboratory; forward a chain e-mail for good luck. Group of participants that exhibited at least one superstitious behavior and the group of participants that did not, differed significantly in the average superstition score.

    The authors' goals are to examine the evolution of the concept of successful aging and its relevance to nursing science and practice. First, the history of positivist construction of aging in light of disengagement and activity theories is presented. Second, an analysis of the postmodern deconstruction of aging is illustrated with the development of the ageism phenomenon. Third, the beginning of the reconstruction of aging is presented and exemplified by Troutman's middle-range nursing theory of successful aging, as connected to Roy's model. Finally, ways in which these theories can be made applicable to nursing practice and research are proposed. PMID:24951524

    1986-06-01

    We construct the particulate states of quantum physics using a recursive computer program that incorporates non-determinism by means of locally arbitrary choices. Quantum numbers and coupling constants arise from the construction via the unique 4-level combinatorial hierarchy. The construction defines indivisible quantum events with the requisite supraluminal correlations, yet does not allow supraluminal communication. Measurement criteria incorporate c, h-bar and m/sub p/ or (not ''and'') G, connected to laboratory events via finite particle number scattering theory and the counter paradigm. The resulting theory is discrete throughout, contains no infinities, and, as far as we have developed it, is in agreement with quantum mechanical and cosmological fact.

    Full Text Available Walking has been shown to improve physical and mental well-being, yet insufficient walking among university students has been increasingly reported. This study aimed to understand walking behavior of university students using theory of planned behavior (TPB. We recruited 169 undergraduate students by university mass email of the Chinese University of Hong Kong, and first administered a salient belief elicitation survey, which was used to design the TPB questionnaire, to a subset of the study sample. Secondly, all participants completed the TPB questionnaire and walking-oriented diary in a two-day period in December 2012. We mapped the walking behavior data obtained from the diary using geographic information system, and examined the extent to which TPB constructs explained walking intentions and walking behavior using Structural equation model (SEM. We found perceived behavioral control to be the key determinant of walking intention. Shaped by participants’ perceived behavioral control, attitude toward walking and subjective norms, and behavioral intention, in turn had a moderate explanatory effect on their walking behavior. In summary, our findings suggest that walking behavior among university students can be understood within the TPB framework, and could inform walking promotion interventions on the university campuses.

    Many theoretical frameworks seek to describe the dynamic process of the implementation of innovations. Little is known, however, about factors related to decisions to adopt innovations and how the likelihood of adoption of innovations can be increased. Using a narrative synthesis approach, this paper compared constructs theorized to be related to adoption of innovations proposed in existing theoretical frameworks in order to identify characteristics likely to increase adoption of innovations. The overall goal was to identify elements across adoption frameworks that are potentially modifiable and, thus, might be employed to improve the adoption of evidence-based practices. The review identified 20 theoretical frameworks that could be grouped into two broad categories: theories that mainly address the adoption process (N = 10) and theories that address adoption within the context of implementation, diffusion, dissemination, and/or sustainability (N = 10). Constructs of leadership, operational size and structure, innovation fit with norms and values, and attitudes/motivation toward innovations each are mentioned in at least half of the theories, though there were no consistent definitions of measures for these constructs. A lack of precise definitions and measurement of constructs suggests further work is needed to increase our understanding of adoption of innovations. PMID:23549911

    Understanding the factors that affect residents’ waste separation behaviors helps in constructing effective environmental campaigns for a community. Using the theory of planned behavior (TPB), this study examines factors associated with waste separation behaviors by analyzing responses to questionnaires distributed in Guangzhou, China. Data drawn from 208 of 1000-field questionnaires were used to assess socio-demographic factors and the TPB constructs (i.e., attitudes, subjective norms, perceived behavioral control, intentions, and situational factors). The questionnaire data revealed that attitudes, subjective norms, perceived behavioral control, intentions, and situational factors significantly predicted household waste behaviors in Guangzhou, China. Through a structural equation modeling analysis, we concluded that campaigns targeting moral obligations may be particularly effective for increasing the participation rate in waste separation behaviors.

    2014-01-01

    Despite the growing body of literature examining the welfare of zoo-housed animals, little standardized work has been published on the effect of construction and environmental disruption on the physiology and behavior of affected animals. When Lincoln Park Zoo (Chicago, IL), embarked on a renovation project for its Kovler Lion House, the opportunity was taken to perform a scientific study of behavioral and physiological markers in the resident felids to determine the effect of construction and environmental disruption. Fecal samples and behavioral observations were collected on four felid species (five individuals) before, during, and after the period of construction. As a group, the average z-score for fecal glucocorticoid metabolite concentration increased during construction relative to baseline. Levels remained elevated after construction, but trended toward baseline. All individuals demonstrated a significant decrease in the frequency of pacing and time spent visible during construction. Overall activity levels also showed a significant decrease relative to baseline measures. As zoological institutions continue to recognize the importance of habitat design, construction and renovation become inevitable. It is important to be aware of the potential consequences this can have on animals in the vicinity and to work toward minimizing negative effects. One recommendation is the availability of ample retreat and hiding space for felids during disruption to their environment. PMID:25042703

Implications for future research directions and policy and practice in the field of special and alternative education are discussed.

  1. The use of Game Theory to solve conflicts in the project management and construction industry

    Directory of Open Access Journals (Sweden)

    José Ramón San Cristóbal

    2015-01-01

    Full Text Available A typical construction project involves a wide range of disparate professionals, in many cases geographically distributed, working together for a relatively short period of time on the design and construction of a facility. Since organizations are becoming flatter, culturally rich, geographically diverse and intensely competitive, the possibilities for conflict in such environments are greater. Negotiation is an important aspect of a project and plays an important role in resolving claims, preventing disputes, and keeping a harmonious relationship between project participants. Part of any project manager’s role as a leader is to recognize conflict, understand the sources of conflict and manage it, and to do this a project manager must be able to understand the basics of negotiation theory and have sufficient competencies to lead in such situations. To address the complex technical and human issues in negotiation, different negotiation theories and models are available which mainly include game theory, economic theory, and behavior theory. Since Game Theory provides, by its very nature, the appropriate tools for the analysis and eventual solution of conflicts of any kind, this paper uses a model based on Game Theory in order to identify the activities that are responsible for the delays in a project and divide the costs among them.

  4. Dendritic solidification morphology viewed from the perspective of constructal theory

    International Nuclear Information System (INIS)

    In this paper we focus on the application of the constructal theory in predicting the dendritic solid structure. First we analyse the marginal stability criterion from the perspective of the constructal principle. Having as a guiding principle the constructal law we have shown that among the whole range of possible dendrite tip radiuses predicted by the stability analysis the dendrite tip will choose the smallest one, that is a radius equal with the smallest perturbation wavelength leading to instabilities. We identify as well the existence of a competition between the diffusion controlled growth and the dendritic growth. Second, we develop a model for the secondary arm spacing. We identify a competition between the lateral diffusion controlled growth of a needle and the dendritic growth of lateral secondary arms. By analysing this competition we are able to characterize the sidebranching mechanism and to finally compute the secondary arm spacing. The result is in good agreement with the experimental results. Finally, the primary arm spacing is analysed from the perspective of the constructal law. The constructal law predicts that the only way the columnar tips can optimize the solidification process is to minimize the spacing between two adjacent tips, namely λ1. By quantifying the two mechanisms responsible for the selection of λ1, the dendrite division and the dendrite overgrown mechanisms, we were finally able to obtain a model for the primary arm spacing. This model is also validated against various experimental data

    Despite strong scientific data indicating associations among sugar-sweetened beverages (SSB) and numerous adverse health outcomes, little is known about culturally specific beliefs and potential individual-level behavioral strategies to reduce SSB intake. The primary objective of this formative study targeting adults residing in rural southwest Virginia was to apply the Theory of Planned Behavior to investigate culturally specific attitudes, subjective norms, and perceived behavioral control constructs related to the consumption of SSB, water, and artificially sweetened beverages. Using a homogenous sampling strategy, eight focus groups were conducted with 54 adult participants who exceeded recommendations of Behavior, to execute the focus group. All focus groups were audiotaped and transcribed verbatim. Three researchers independently coded meaning units to the major themes and subsequently met to gain consensus in coding. Important beverage-specific themes emerged for attitudes, subjective norms, perceived behavioral control, and intentions. Across all beverages, the most notable themes included taste (n=161 meaning units), availability/convenience (n=95 meaning units), habit/addiction (n=57 meaning units), and cost (n=28 meaning units). Health consequences associated with beverages and water-quality issues also surfaced, as well as normative beliefs, including the influence of doctors and peers. The identified themes and subthemes provide critical insight into understanding culturally relevant context and beliefs associated with beverage consumption behaviors and helps inform the development and evaluation of future intervention efforts targeting SSB consumption in the health disparate region of southwest Virginia.

    The Theory of Planned Behavior (TPB) was used to assess subjects' intentions and behavior to predict willingness to undergo prosthodontic care. A questionnaire was administered to 225 adults with history of teeth loss who currently were not under prosthodontic treatment. The questionnaire comprised TPB components (attitude toward behaviour [ATB], subjective norm [SN], and perceived behavioral control [PBC]) containing items with potential influence on the intentions and behavior of individuals toward prosthodontic care. Clinical and socioeconomic data were also assessed. A path regression model was constructed explaining two dependent variables simultaneously: one explained the influence of PBC on intention (R2=0.04) and another explained the influence of dental arch, position of lost teeth, socioeconomic status, and PBC on behavior (R2=0.31). It was concluded that PBC was a relevant TPB component that encompasses perception of costs, opportunity cost, perceived need, and access to dental care. Clinical and socioeconomic factors were also major determinants of behavior toward prosthodontic treatment. PMID:26929951

Numerical analysis on parameters is conducted to reveal the complexity and influence of the evolution. Simulation results show that the factor, which indicated the balance of payments structure between supervisor unit and contractor, was closely related with the volatility of the dynamic evolutionary procedure. The results also show that compared with the static penalty strategy, the dynamic penalty strategy can effectively stabilize the fluctuation during the evolutionary game procedure.

    Plaud, J J; Gaither, G A

    1996-04-01

    Historical and contemporary theories of reinforcement, as well as the clinical application of reinforcement principles to behavior modification and therapy, are critically analyzed and discussed. A new behavioral approach to studying the allocation of behavior under changed environmental constraints, termed behavioral momentum, is also presented. Whereas traditional behavioral analysis has emphasized the role of response rate as an index of response probability and response strength, more recent studies have addressed the persistence of behavior under altered environmental conditions and reinforcement contingencies. In terms of behavior modification and therapy, issues such as generalizability and relapse prevention have major implications for the type and length of behavioral intervention strategies employed. The behavioral momentum model analyzes operant behavior not only in terms of its response rate but also in relation to its persistence under changed environmental constraints. The authors discuss the applicability of this recent addition to reinforcement theories in context of its implications for behavior modification and therapy. PMID:8934866

    Although logarithmic conformal field theories (LCFTs) are known not to factorise many previous findings have only been formulated on their chiral halves. Making only mild and rather general assumptions on the structure of an chiral LCFT we deduce statements about its local non-chiral equivalent. Two methods are presented how to construct local representations as subrepresentations of the tensor product of chiral and anti-chiral Jordan cells. Furthermore we explore the assembly of generic non-chiral correlation functions from generic chiral and anti-chiral correlators. The constraint of locality is studied and the generality of our method is discussed.

  13. Constructal Theory Of Design In Engineering And Nature

    Adrian Bejan

    2005-02-01

    Full Text Available This is a brief introduction to an engineering theory on the origin and generation of geometric form in all flow systems: the animate, the inanimate and the engineered. The theory is named constructal, and is based on the thought that it is natural for currents to construct for themselves in time paths of greater flow access. It is shown that this process of flow path optimization can be reasoned on the basis of principle: the maximization of global performance subject to finite-size constraints. One example is the generation of tree-shaped flow patterns, as paths of least resistance between one point (source, sink and an infinity of points (area, volume, as in the circulatory, respiratory and nervous systems. An other is the generation of regular spacings in heat generating volumes, such as swarms of honeybees. The optimized tree-flow geometries account for allometric laws, e. g., the relationship between the total tube contact area and the body size, the proportionality between metabolic rate and body size raised to the power 3/4, the proportionality between breathing and heartbeating times and body size raised to the power 1/4, and the proportionality between the cruising speed of flying bodies (insects, birds, airplanes and body mass raised to the power 1/6. The optimized flow structures constitute robust designs, and robustness improves as the complexity of the system increases. Flow architectures that are more efficient look more natural.

    Over the past century, rooted in the theory of general relativity, cosmology has developed a very successful physical model of the universe: the {\\em big-bang model}. Its construction followed different stages to incorporate nuclear processes, the understanding of the matter present in the universe, a description of the early universe and of the large scale structure. This model has been confronted to a variety of observations that allow one to reconstruct its expansion history, its thermal history and the structuration of matter. Hence, what we refer to as the big-bang model today is radically different from what one may have had in mind a century ago.

    Introduction & Objective: Injuries resulting from ignoring proper working posture especially in employees who sitting at workplace for more than of working hours are costly, and create significant pain and discomfort. Decreasing of these injuries is most effectively accomplished through the application of ergonomic design principles. Sometimes, however, barriers (technical and economic preclude ergonomic improvement and, consequently, some organizations rely on the use of proper sitting techniques and maintaining proper working posture as a major control strategy during workday. The problem, however, is that these process performing is inconsistent and managers have a difficult time motivating use of these techniques. The main aim of this study was to understand the factors driving proper working posture among employees. Materials & Methods: This study used the theory of planned behavior to predict upright working posture maintenance among 222 of assembling, machinery and printing line’s employees at a Qazvin Alborz industrial town manufacturing organization. Structural equation modeling, explanatory and confirmatory factor analysis were employed to analyze relationships among constructs. Results: Results revealed that attitude (p< 0.05, β= 0.53 and intention (p< 0.05, β= 0.46 were the strongest predictors of proper working posture maintenance behavior. Perceived behavior control, to a lesser degree, were also important influences on intention (p< 0.05, β= 0.34 and behavior (p< 0.05, β= 0.28. Subjective norms did not surface as effective direct predictors of upright working posture maintenance, but did affect behavior and intent via mediating factors (attitudes subjective norms and perceived behavioral control. Finally, the TPB was supported as an effective model explaining upright working posture maintenance, and had potential application for many other safety-related behaviors. Conclusion: results of this study emphasis on considering factors such as

    2014-09-01

    This work presents the results of a case study and describes an important area within the field of construction safety management, namely behavior-based safety (BBS). This paper adopts and develops a management approach for safety improvements in construction site environments. A rigorous behavioral safety system and its intervention program was implemented and deployed on target construction sites. After taking a few weeks of safety behavior measurements, the project management team implemented the designed intervention and measurements were taken. Goal-setting sessions were arranged on-site with workers' participation to set realistic and attainable targets of performance. Safety performance measurements continued and the levels of performance and the targets were presented on feedback charts. Supervisors were asked to give workers recognition and praise when they acted safely or improved critical behaviors. Observers were requested to have discussions with workers, visit the site, distribute training materials to workers, and provide feedback to crews and display charts. They were required to talk to operatives in the presence of line managers. It was necessary to develop awareness and understanding of what was being measured. In the process, operatives learned how to act safely when conducting site tasks using the designed checklists. Current weekly scores were discussed in the weekly safety meetings and other operational site meetings with emphasis on how to achieve set targets. The reliability of the safety performance measures taken by the company's observers was monitored. A clear increase in safety performance level was achieved across all categories: personal protective equipment; housekeeping; access to heights; plant and equipment, and scaffolding. The research reveals that scores of safety performance at one project improved from 86% (at the end of 3rd week) to 92.9% during the 9th week. The results of intervention demonstrated large decreases in

  19. A general construction of conformal field theories from scalar anti-de Sitter quantum field theories

    International Nuclear Information System (INIS)

    We provide a new general setting for scalar interacting fields on the covering of a ( d+1 )-dimensional AdS spacetime. The formalism is used at first to construct a one-parameter family of field theories, each living on a corresponding spacetime submanifold of AdS, which is a cylinder RxSd-1 . We then introduce a limiting procedure which directly produces Luescher-Mack CFT's on the covering of the AdS asymptotic cone. Our generalized AdS → CFT construction is nonperturbative, and is illustrated by a complete treatment of two-point functions, the case of Klein-Gordon fields appearing as particularly simple in our context. We also show how the Minkowskian representation of these boundary CFT's can be directly generated by an alternative limiting procedure involving Minkowskian theories in horocyclic sections (nowadays called (d-1)-branes, 3-branes for AdS5 ). These theories are restrictions to the brane of the ambient AdS field theory considered. This provides a more general correspondence between the AdS field theory and a Poincare invariant QFT on the brane, satisfying all the Wightman axioms. The case of two-point functions is again studied in detail from this viewpoint as well as the CFT limit on the boundary

  2. [Behavioral Activation for Depression: Theory and Practice].

    Nakao, Tomohiro

    2015-01-01

    Behavioral activation (BA) has recently attracted marked attention. While cognitive therapy focuses on the cognitive distortion of patients with depression and asks them to change their behaviors as the process of altering the cognitive distortion, BA pays attention to behavior to avoid an unpleasant situation or social situation as a key symptom that leads to persistence of the depression. Avoidance behaviors are often seen during every process of depression, from onset to recurrence. Avoidance behaviors, a decrease in pleasant phenomena, or increase in unpleasant phenomena, result in reinforcing a depressive mood. If patients can set appropriate behavioral targets and achieve them, the beneficial behaviors will be further promoted with positive feed-back. The behavioral change, as-a consequence, will result in improvement of the mood, cognition, and depression itself. In this manuscript, the author presents two clinical cases, in which BA assisted the patients in recovering from their depression. The first case was a male in his thirties who repeatedly took sick leave from his work because of maladjustment, which resulted in persistent depression. The second case was a female in her thirties who suffered from OCD and then became maladjusted to her place of work, depressive, and emotionally unstable. In both cases, avoidant behaviors caused their conditions to persist. Appropriate activities formed by BA improved their moods, and their self-efficacies were gradually regained. It was suggested that BA is markedly effective, especially in patients whose avoidant behaviors mainly cause the persistence of their depressive symptoms. PMID:26514042

    Weinstein, N D

    1993-07-01

    Four competing theories of health-protective behavior are reviewed: the health belief model, the theory of reasoned action, protection motivation theory, and subjective expected utility theory. In spite of their commonalities, these models are seldom tested against one another. The review points out the similarities and differences among these theories and the data and analyses needed to compare them. In addition to describing the content of the models, their conceptualization of key variables, and the combinatorial rules used to make predictions, some general problems in theory development and testing for health behaviors are examined. The article's goal is to help investigators design studies that will clarify the strengths and weaknesses of these models, leading toward a better understanding of health behavior. PMID:8404807

    2015-12-01

    This article addresses criticisms of qualitative research for spawning studies that lack analytic development and theoretical import. It focuses on teaching initial grounded theory tools while interviewing, coding, and writing memos for the purpose of scaling up the analytic level of students' research and advancing theory construction. Adopting these tools can improve teaching qualitative methods at all levels although doctoral education is emphasized here. What teachers cover in qualitative methods courses matters. The pedagogy presented here requires a supportive environment and relies on demonstration, collective participation, measured tasks, progressive analytic complexity, and accountability. Lessons learned from using initial grounded theory tools are exemplified in a doctoral student's coding and memo-writing excerpts that demonstrate progressive analytic development. The conclusion calls for increasing the number and depth of qualitative methods courses and for creating a cadre of expert qualitative methodologists. PMID:26646825

    Mas, Francisco G Soto; Plass, Jan; Kane, William M; Papenfuss, Richard L

    2003-07-01

    When health education researchers began to investigate how individuals make decisions related to health and the factors that influence health behaviors, they referred to frameworks shared by educational and learning research. Health education adopted the basic principles of the cognitive revolution, which were instrumental in advancing the field. There is currently a new challenge to confront: the widespread use of new technologies for health education. To better overcome this challenge, educational psychology and instructional technology theory should be considered. Unfortunately, the passion to incorporate new technologies too often overshadows how people learn or, in particular, how people learn through computer technologies. This two-part article explains how educational theory contributed to the early development of health behavior theory, describes the most relevant multimedia learning theories and constructs, and provides recommendations for developing multimedia health education programs and connecting theory and practice.

    Full Text Available Abstinence from smoking on the morning of surgery may improve outcomes. This study examined the explicatory power of the Theory of Planned Behavior (TPB to predict smoking behavior on the morning of surgery, testing the hypothesis that the constructs of attitude, subjective norm, and perceived behavioral control (PBC will predict intent to abstain from smoking the morning of surgery, and that intent will predict behavior. TPB constructs were assessed in 169 pre-surgical patients. Smoking behavior on the morning of surgery was assessed by self-report and CO monitoring. Correlations and structural equation modeling (SEM were used to determine associations between measures and behavior. All TPB measures, including intent as predicted by the TPB, were correlated with both a lower rate of self-reported smoking on the morning of surgery and lower CO levels. The SEM showed a good fit to the data. In the SEM, attitude and PBC, but not subjective norm, were significantly associated with intent to abstain, explaining 46% of variance. The effect of PBC on CO levels was partially mediated by intent. The amount of variance in behavior explained by these TPB constructs was modest (10% for CO levels. Thus, attitude and perceived behavioral control explain a substantial portion of the intent to maintain preoperative abstinence on the morning of elective surgery, and intent and perceived behavioral control explain a more modest but significant amount of the variance in actual smoking behavior.Clinical Trials.gov registration: NCT01014455.

    Full Text Available Backgrounds. The aim of this study was to describe the preventive behaviors of industrial workers and factors influencing occupational cancer prevention behaviors using protection motivation theory. Methods. A self-administered questionnaire was completed by 161 petrochemical workers in Iran in 2014 which consisted of three sections: background information, protection motivation theory measures, and occupational cancers preventive behaviors. Results. A statistically significant positive correlation was found between PM and self-efficacy, response efficacy, and the cancer preventive behaviors. Meanwhile, statistically significant negative correlations were found between PM, cost, and reward. Conclusions. Among available PMT constructs, only self-efficacy and cost were significant predictors of preventive behaviors. Protection motivation model based health promotion interventions with focus on self-efficacy and cost would be desirable in the case of occupational cancers prevention.

    With the proposal of sustainable development and green building, construction waste minimization is becoming a hot point of research. As the Chinese construction industry is still labor-intensive, the awareness toward construction waste reduction of construction personnel directly or indirectly influences construction waste generation. Therefore, from the perspective of construction personnel, this paper was to explore the relationship between their awareness and behavior toward construction waste minimization. Based on the theory of planned behavior, the questionnaire survey for construction personnel on wasteful behavior and awareness of construction waste was designed by site interviews. The structural equation model concerning the involvement of individual awareness and behavior regarding waste minimization was built to explore the relationship between awareness and behavior on the basis of high reliability and validity of the scale. Through questionnaire survey, the validated model demonstrated that the attitude from construction workers on construction waste minimization exerts greatest influence on behavioral intention. However, their behavioral intention is unable to predict behavior, while Perceived Behavioral Control has a significant effect on behavior.%随着可持续发展和绿色建筑的提出,建筑废弃物减量化正成为一个研究热点.建筑行业属劳动密集型,建筑废弃物的产生直接或间接地受施工人员行为意识的影响.本文从施工人员的角度出发,探讨其建筑废弃物减量化意识与行为之间的关系.基于计划行为理论,结合访谈创建了施工人员建筑废弃物减量化行为意识量表,在保证量表有良好的信度和效度的前提下,构建了施工人员建筑废弃物减量化行为意识结构方程模型,并通过问卷调查收集数据对模型进行了验证.结果表明,施工人员的减量化态度对其行为倾向影响最大,而行为倾向不能够预测实际行

    1998-01-01

    We study under which conditions an overdamped regime can be attained in the dynamic evolution of a quantum field configuration. Using a real-time formulation of finite temperature field theory, we compute the effective evolution equation of a scalar field configuration, quadratically interacting with a given set of other scalar fields. We then show that, in the overdamped regime, the dissipative kernel in the field equation of motion is closely related to the shear viscosity coefficient, as computed in scalar field theory at finite temperature. The effective dynamics is equivalent to a time-dependent Ginzburg-Landau description of the approach to equilibrium in phenomenological theories of phase transitions. Applications of our results, including a recently proposed inflationary scenario called ``warm inflation'', are discussed.

    2011-01-01

    We propose the construction of an unobservable communications network using social networks. The communication endpoints are vertices on a social network. Probabilistically unobservable communication channels are built by leveraging image steganography and the social image sharing behavior of users. All communication takes place along the edges of a social network overlay connecting friends. We show that such a network can provide decent bandwidth even with a far from optimal routing mechanism such as restricted flooding. We show that such a network is indeed usable by constructing a botnet on top of it, called Stegobot. It is designed to spread via social malware attacks and steal information from its victims. Unlike conventional botnets, Stegobot traffic does not introduce new communication endpoints between bots. We analyzed a real-world dataset of image sharing between members of an online social network. Analysis of Stegobot's network throughput indicates that stealthy as it is, it is also functionally p...

    Full Text Available Background and Objectives: The cognitive determinants of social behaviors play an important role in adolescents' decision-making for starting smoking. The present study was therefore conducted to determine the predictors of tobacco smoking in male adolescents in Hamadan, Iran, based on the Theory of Planned Behavior (TPB. Materials and Methods: The present descriptive-analytical study was conducted on 810 male high school students in Hamadan selected through the multistage sampling method. Data were collected using a self-report questionnaire with a section on participants' demographic information and another section based on the TPB constructs. Data were then analyzed in SPSS-18 and AMOS-18 using the Pearson correlation test and the indices of model fit. Results: Overall, 17.2% of the male adolescents reported to have smoked cigarettes in the past. Perceived behavioral control, subjective norms and attitude were the best predictors of behavioral intention for tobacco smoking, in the order of importance (P<0.001. Perceived behavioral control (&beta=-0.59 P<0.001 was a better predictor of the studied behavior than behavioral intention (&beta=0.11 P<0.001. In the structural equation model, TPB constructs accounted for 32% of behavioral intention variances and 50% of behavior variances. Conclusion: The results demonstrated the poor role of behavioral intention in reporting smoking behaviors in male adolescents. Other psychological factors that affect adolescents' decision-making regarding tobacco smoking should also be scrutinized.

    identity, distinctive behavioral patterns, ideal-seeking, curiosities, interactions, and subcultures of students in experiencing living with one another which they share upon entering the university. When it comes to school and university students, deviant behaviors could be consumption of any drugs and addictive substance, vandalism, robbery, sexual perversion and so on. Multiple studies have been conducted on identification of the factors behind emergence and development of deviant behaviors among samples of school and university students in local and international research which undoubtedly point to significance of investigating this matter. Considering the extensiveness of the issue, lack of precision instruments for measuring deviant behaviors shows a gap ignored in the previous research, such that one could claim that in none of the studies carried out in Iran, constructing measurement tools and scales for deviant behaviors and their normalization have not yet been taken into account by the researchers dealing with this area. Of course, each of the tools available for measuring deviant behaviors in different countries have specific features and characteristics and their goals, target population and construction underlying theories are completely different. At the same time, the most important issue is constructing a tool based on definition(s and instances of deviant behaviors according to the intended context. Another important point is designing and constructing such tools on the base of recent theories of measurement. Since the issue of measuring deviant behaviors and constructing its measurement tools and scales have not seriously considered in Iran thus far, and in view of dire need of the society and various organizations, particularly the Ministry of Science and National Youth Organization, presence of scientific measurement tools which are in agreement with the cultural structure of Iran is demanded more than ever. Therefore, developing the relevant tests

    2016-02-01

    We study the perturbative phase diagram of semisimple fermionic gauge theories resembling the Standard Model. We investigate an S U (N ) gauge theory with M Dirac flavors where we gauge first an S U (M )L and then an S U (2 )L⊂S U (M )L of the original global symmetry S U (M )L×S U (M )R×U (1 ) of the theory. To avoid gauge anomalies we add leptonlike particles. At the two-loop level an intriguing phase diagram appears. We uncover phases in which one, two or three fixed points exist and discuss the associated flows of the coupling constants. We discover a phase featuring complete asymptotic freedom and simultaneously an interacting infrared fixed point in both couplings. The analysis further reveals special renormalization group trajectories along which one coupling displays asymptotic freedom and the other asymptotic safety, while both flowing in the infrared to an interacting fixed point. These are safety free trajectories. We briefly sketch out possible phenomenological implications, among which an independent way to generate near-conformal dynamics à la walking is investigated.

    Einstein classified various theories in physics as principle-theories and constructive-theories. In this lecture Kondo's approach to microscopic and macroscopic phenomena is analysed for its principle theoretic pursuit as followed by construction. The fundamentals of his theory may be recalled as Tristimulus principle, Observation principle, Kawaguchi spaces, empirical information, epistemological point of view, unitarity, intrinsicality, and dimensional analysis subject to logical and geometrical achievement. On the other hand, various physicists have evolved constructive gauge theories through the phenomenological point of view, often a collective one. Their synthetic method involves fibre bundles and connections, path integrals as well as other hypothetical structures. They lead towards clarity, completeness and adaptability

    Many trends in alloy phase formation are readily understood in terms of physically plausible atomic parameters. This has led to the introduction of structural maps where two (or more) such atomic parameters are employed as the coordinates and well-defined regions are observed to be associated with particular crystalline phases. These coordinates sometimes involve the difference in atomic parameters and sometimes involve an average. An alternative approach to the emphasis on atomic parameters has been the consideration of how atoms are packed in some crystal structure and how this controls what the constituent atoms may be. Recently this has led to the utilization of Wigner-Seitz (sometimes called Voronoi or Dirichlet) constructs of the atomic cells in a crystal structure and to the observation that sometimes two crystals which are nominally considered to have the same crystal structure according to normal crystallographic designation should be considered to be different. The Wigner-Seitz cell constructs have also offered a framework for understanding trends in the magnetic and chemical properties of particular phases as well as making coordination between crystalline and glassy structures. Neither of the above approaches provides numerical estimates of quantities of thermodynamic interest such as heats of formation. Such heats are being calculated. 42 refs., 15 figs

    The theory of planned behavior (TPB) has been successfully predicting behavior with a small number of factors. Nonetheless, to increase its predictive power we introduced several behavioral options and additional factors in the same prediction model about drivers’ self-reported speed behavior on a road with a speed limit of 90 km/h. We investigated the TPB factors as well as descriptive norms, perceived similarity with/description of the prototypical driver, and past behavior with re...

    Full Text Available This study is the first phase of the formative research recommended in the Theory of Planned Behavior for the development of an intervention. Our aims are to identify modal beliefs about the performance of an exercise pattern in people with fibromyalgia, to test the items designed for direct evaluation of the predictive constructs and to explore their relationships with the behavior. We assessed 46 women with fibromyalgia. Content analysis showed more positive than negative consequences related to the performance of exercise guidelines (behavioral beliefs. Families and friends are the important referents (normative beliefs and we identified facilitating and inhibiting factors in the performance of exercise behavior related to aspects of fibromyalgia (control beliefs such as pain, fatigue and emotional state. The subjective norm scale showed the lowest internal consistency (α= .78. The results confirmed the sedentary lifestyle of the participants (previous behavior: Mean=3.67; rank=1-7 although they also suggested that participants intended to perform the behavior (Mean=5.67. The relationships between constructs are coherent with the theory, and support the relevance of applying it to the selected behavior and population.

    Full Text Available Background Smoking among the youth is an important public health concern. Although several studies have investigated the correlates of smoking behavior, no theory-based study has particularly assessed this problem among medical students. Objectives This study aimed to evaluate the efficacy of the extended theory of planned behavior (TPB to predict smoking behavior among a sample of Iranian medical students. Patients and Methods This is a cross-sectional study carried out in Ahvaz, Iran, 2014. The data were collected through a self-administered questionnaire, which included items on demographics, smoking behavior, and components of the TPB model (attitude, subjective norms, perceived behavior control, and intention, and an added construct on smoking refusal skill. Data were analyzed using descriptive correlation, and linear regression statistics by SPSS, version 16. Results One hundred and seventy medical students with a mean age of 21.25 (SD = 2.9 years were enrolled in the study. Of them, 24 (13.5% students were smokers. All components of the TPB model and smoking refusal skill were statistically significant as to intention to smoke (P < 0.001. The TPB constructs with and without smoking refusal skill accounted for 77% (adjusted R2 and 78% of the variance observed for intention to smoke, respectively. The results also revealed the highest weight for perceived behavior control (β= -0.40. Conclusions The findings of this study indicated that all TPB variables are useful tools for prediction of the smoking behaviors among students. Particularly, students’ perceived behavioral control and attitudes towards smoking were found to be important determinants of smoking intentions. Thus, the findings could be used for planning effective tobacco control programs targeting University students.

    2015-03-01

    Full Text Available Background and Objectives: The world population has reached over seven billion people. Of these, 230 million individuals abuse substances. Therefore, substance abuse prevention and treatment programs have received increasing attention during the past two decades. Understanding people’s motivations for quitting drug abuse is essential to the success of treatment. This study hence sought to identify major motivations for quitting and to compare them with the constructs of health education models. Materials and Methods: In the present study, qualitative content analysis was used to determine the main motivations for quitting substance abuse. Overall, 22 patients, physicians, and psychotherapists were selected from several addiction treatment clinics in Bojnord (Iran during 2014. Purposeful sampling method was applied and continued until data saturation was achieved. Data were collected through semi-structured, face-to-face interviews and field notes. All interviews were recorded and transcribed. Results: Content analysis revealed 33 sub-categories and nine categories including economic problems, drug-related concerns, individual problems, family and social problems, family expectations, attention to social status, beliefs about drug addiction, and valuing the quitting behavior. Accordingly, four themes, i.e. perceived threat, perceived barriers, attitude toward the behavior, and subjective norms, were extracted. Conclusion: Reasons for quitting substance abuse match the constructs of different behavioral models (e.g. the health belief model and the theory of planned behavior.

  17. Explaining exercise behavior and satisfaction with social exchange theory.

    Unger, J; Johnson, C A

    1995-10-01

    This study tested the hypothesis that the variables specified by social exchange theory (perceived rewards of exercising, perceived costs of exercising, social and tangible investments, and available alternative activities) are associated with exercise behavior and satisfaction. 190 health club members completed a questionnaire assessing attitudes toward exercise, exercise behavior, and demographic information. Exercise frequency and satisfaction were regressed on the social exchange theory variables and demographic covariates. Exercise satisfaction, the number of investments in exercise, and the number of available alternative activities were significantly related to exercise frequency, and the number of perceived rewards of exercise and the number of investments were significantly related to exercise satisfaction. These results suggest that social exchange theory is useful for explaining exercise behavior. PMID:8570365

    Using lattice simulations, we study the infrared behavior of a particularly interesting SU(2) gauge theory, with six massless Dirac fermions in the fundamental representation. We compute the running gauge coupling derived nonperturbatively from the Schrödinger functional of the theory, finding no evidence for an infrared fixed point up through gauge couplings g(2) of order 20. This implies that the theory either is governed in the infrared by a fixed point of considerable strength, unseen so far in nonsupersymmetric gauge theories, or breaks its global chiral symmetries producing a large number of composite Nambu-Goldstone bosons relative to the number of underlying degrees of freedom. Thus either of these phases exhibits novel behavior. PMID:24702347

    2007-01-01

    The most comprehensive and applied discussion of stated choice experiment constructions available The Construction of Optimal Stated Choice Experiments provides an accessible introduction to the construction methods needed to create the best possible designs for use in modeling decision-making. Many aspects of the design of a generic stated choice experiment are independent of its area of application, and until now there has been no single book describing these constructions. This book begins with a brief description of the various areas where stated choice experiments are applicable, including marketing and health economics, transportation, environmental resource economics, and public welfare analysis. The authors focus on recent research results on the construction of optimal and near-optimal choice experiments and conclude with guidelines and insight on how to properly implement these results.

    Full Text Available Introduction: Unsafe sexual behaviors as important risky behaviors can expose individuals and society to dangerous infectious disease such as AIDS and viral hepatitis. Considering the high prevalence of unsafe sexual behaviors, this study aimed to determine the effect of educational programs to encourage safe sexual behaviors among substance abusers referred to substance abuse treatment centers in Hamadan, Western Iran by applying the theory of planned behavior. Materials & Methods: This quasi-experimental study was performed on 104 men substance abusers (52 participants in each of the control and intervention groups referred to substance abuse treatment centers in Hamadan. Data collection tool was a questionnaire containing demographic information and the theory of planned behavior constructs. Before the educational program, questionnaires were completed by both groups. After the pretest in both groups, participants in the intervention group participated in four educational sessions designed based on the theory of planned behavior. Two months after the end of program, posttest was performed. Data was analyzed using independent T-test, chi-square, fisher exact test, McNemar’s test and multiple linear regressions using SPSS-16. Results: After educational intervention, the mean scores of the theory constructs (attitude toward behavior, subjective norms, behavioral control, behavioral intention and behaviors, in the intervention group increased significantly (P<0.05, despite the fact, changes were not significant in the control group. Conclusion: Implementation of educational courses to encourage safe sexual behaviors based on the theory of planned behavior can be beneficial for substance abusers referred to substance abuse treatment centers.

  14. Toward Principles of Construct Clarity: Exploring the Usefulness of Facet Theory in Guiding Conceptualization

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available Conceptualization in theory development has received limited consideration despite its frequently stressed importance in Information Systems research. This paper focuses on the role of construct clarity in conceptualization, arguing that construct clarity should be considered an essential criterion for evaluating conceptualization and that a focus on construct clarity can advance conceptualization methodology. Drawing from Facet Theory literature, we formulate a set of principles for assessing construct clarity, particularly regarding a construct’s relationships to its extant related constructs. Conscious and targeted attention to this criterion can promote a research ecosystem more supportive of knowledge accumulation.

    The perception-related origins of physical measures and standards are considered within the framework of the general observer theory. The impact of observer characteristics on the development of observer-centric physics, physical concepts and metrics are analyzed. A preliminary theoretical approach is suggested for the construction of a general observer theory and formulation of its relationship to observer-centered physical concepts and theories. The approach makes it possible to construct a theory of the observer, intrinsic in any theory of physics.

    Level of physical activity as a key determinant of healthy lifestyle less than is required in individuals particularly women. Applying theories of behavioral change about complex behaviors such as physical activity leads to identify effective factors and their relations. The aim of this study was to determine predictors of physical activity behavior based on the Theory of Planned Behavior in military staff's wives in Tehran. This cross-sectional study was performed in 180 military personnel's spouses residing in organizational houses, in Tehran, Iran in 2014. The participants were randomly selected with multi-stage cluster sampling. The validity and reliability of the theory based scale evaluated before conducting the path analysis. Statistical analysis was carried out using SPSS16 and LISREL8.8. The results indicated the model explained 77% and 17% of intention and behavior variance. Subjective norms (Beta=0.83) and intention (Beta=0.37) were the strongest predictors of intention and behavior, respectively. The instrumental and affective attitude had no significant path to intention and behavior. The direct relation of perceived behavioral control to behavior was non-significant. This research demonstrated relative importance and relationships of Theory of Planned Behavior constructs in physical activity behavior of military personnel's spouses in Tehran. It is essential to consider these determinants in designing of educational interventions for promoting and maintaining physical activity behavior in this target group. PMID:25948459

    The aim of the present studies was to verify the basic assumptions underlying the theory of planned behavior for the prediction of exercising intentions and behavior among adults of the general population (study 1) and a group of pregnant women (study 2). In both studies, baseline data were collected at home with trained interviewers and with the use of paper-and-pencil questionnaires. The self-report on behavior was obtained 6 months (study 1) and between 8 and 9 months (study 2) after baseline data collection. In study 1, perceived behavioral control influenced behavior only through intention. In study 2, none of the Ajzen model variables was associated to exercising behavior. Nonetheless, intention was influenced by attitude, habit, and perceived behavioral control. The results of the present studies suggest that perceived behavioral control contributes to the understanding of intentions to exercise but not to the prediction of exercising behavior. PMID:8433359

    The theory of planned behavior explores the relationship between behavior, beliefs, attitudes, and intentions presupposing that behavioral intention is influenced by a person’s attitude about the behavior and beliefs about whether individuals, who are important to them, approve or disapprove of the behavior (subjective norm). An added dimension to the theory is the idea of perceived behavioral control, or the belief that one has control over performing the behavior. The theory of planned beha...

  11. Building theories of knowledge translation interventions: Use the entire menu of constructs

    Full Text Available Abstract Background In the ongoing effort to develop and advance the science of knowledge translation (KT, an important question has emerged around how theory should inform the development of KT interventions. Discussion Efforts to employ theory to better understand and improve KT interventions have until recently mostly involved examining whether existing theories can be usefully applied to the KT context in question. In contrast to this general theory application approach, we propose a ‘menu of constructs’ approach, where individual constructs from any number of theories may be used to construct a new theory. By considering the entire menu of available constructs, rather than limiting choice to the broader level of theories, we can leverage knowledge from theories that would never on their own provide a complete picture of a KT intervention, but that nevertheless describe components or mechanisms relevant to it. We can also avoid being forced to adopt every construct from a particular theory in a one-size-fits-all manner, and instead tailor theory application efforts to the specifics of the situation. Using audit and feedback as an example KT intervention strategy, we describe a variety of constructs (two modes of reasoning, cognitive dissonance, feed forward, desirable difficulties and cognitive load, communities of practice, and adaptive expertise from cognitive and educational psychology that make concrete suggestions about ways to improve this class of intervention. Summary The ‘menu of constructs’ notion suggests an approach whereby a wider range of theoretical constructs, including constructs from cognitive theories with scope that makes the immediate application to the new context challenging, may be employed to facilitate development of more effective KT interventions.

    Full Text Available Hartmut Meister,1 Linda Grugel,1 Markus Meis2 1Jean Uhrmacher Institute for Clinical ENT Research, University of Cologne, Cologne, Germany; 2Hoerzentrum Oldenburg, Oldenburg, Germany Objective: To determine the intention to use hearing aids (HAs by applying the theory of planned behavior (TPB. Design: The TPB is a widely used decision-making model based on three constructs hypothesized to influence the intention to perform a specific behavior; namely, “attitude toward the behavior”, “subjective norm”, and “behavioral control”. The survey was based on a TPB-specific questionnaire addressing factors relevant to HA provision. Study sample: Data from 204 individuals reporting hearing problems were analyzed. Different subgroups were established according to the stage of their hearing help-seeking. Results: The TPB models’ outcome depended on the subgroup. The intention of those participants who had recognized their hearing problems but had not yet consulted an ear, nose, and throat specialist was largely dominated by the “subjective norm” construct, whereas those who had already consulted an ear, nose, and throat specialist or had already tried out HAs were significantly influenced by all constructs. The intention of participants who already owned HAs was clearly less affected by the “subjective norm” construct but was largely dominated by their “attitude toward HAs”. Conclusion: The intention to use HAs can be modeled on the basis of the constructs “attitude toward the behavior”, “subjective norm”, and “behavioral control”. Individual contribution of the constructs to the model depends on the patient’s stage of hearing help-seeking. The results speak well for counseling strategies that explicitly consider the individual trajectory of hearing help-seeking. Keywords: hearing aid uptake, motivation, attitude, subjective norm, behavioral control

    Full Text Available Institutionalism is the syndrome first recognized and described in inpatient psychiatric facilities,which is now used to describe a set of maladaptive behaviors that are evoked by the pressures of living in any institutional setting. This article traces the development of the theory of institutionalization, which predicts and explains an individual’s response to that particular type of environment. The article makes note of key contributors and contributions, and of empirical studies that have advanced the theory. Underlying perspectives and assumptions are identified and earlier theoretical models are reviewed and critiqued. An updated model of the theory, which includes individual vulnerabilities, objective conditions of the institutional placement, and the resident’s perceptions of the environment, is presented. New directions in the field of institutional care and implications for social workers, particularly for those working in nursing home and prison settings, are discussed, along with recommendations for next steps for theory progression.

    2014-01-01

    Full Text Available This paper proposes a route choice analytic method that embeds cumulative prospect theory in evolutionary game theory to analyze how the drivers adjust their route choice behaviors under the influence of the traffic information. A simulated network with two alternative routes and one variable message sign is built to illustrate the analytic method. We assume that the drivers in the transportation system are bounded rational, and the traffic information they receive is incomplete. An evolutionary game model is constructed to describe the evolutionary process of the drivers’ route choice decision-making behaviors. Here we conclude that the traffic information plays an important role in the route choice behavior. The driver’s route decision-making process develops towards different evolutionary stable states in accordance with different transportation situations. The analysis results also demonstrate that employing cumulative prospect theory and evolutionary game theory to study the driver’s route choice behavior is effective. This analytic method provides an academic support and suggestion for the traffic guidance system, and may optimize the travel efficiency to a certain extent.

    The reasoned action approach, although ubiquitous in health behavior theory (e.g., Theory of Reasoned Action/Planned Behavior), does not adequately address two key dynamical aspects of health behavior: learning and the effect of immediate social context (i.e., social influence). To remedy this, we put forth a computational implementation of the Theory of Reasoned Action (TRA) using artificial-neural networks. Our model re-conceptualized behavioral intention as arising from a dynamic constraint satisfaction mechanism among a set of beliefs. In two simulations, we show that constraint satisfaction can simultaneously incorporate the effects of past experience (via learning) with the effects of immediate social context to yield behavioral intention, i.e., intention is dynamically constructed from both an individual's pre-existing belief structure and the beliefs of others in the individual's social context. In a third simulation, we illustrate the predictive ability of the model with respect to empirically derived behavioral intention. As the first known computational model of health behavior, it represents a significant advance in theory towards understanding the dynamics of health behavior. Furthermore, our approach may inform the development of population-level agent-based models of health behavior that aim to incorporate psychological theory into models of population dynamics.

    A Grounded Theory on Helping Behavior and Its Shaping Factors

    2006-06-01

    Full Text Available In social psychology, the attribution model of helping behavior suggests that beliefs of the helping target’s responsibility for the need for help evoke affective motivators such as feelings of pity, sympathy, or anger. The affective motivation leads to helping or not helping the target. The current emergent theory is an enhancement of this theory by incorporating other personal and situational variables.Through the use of classic grounded theory, I interviewed 80 participants from different De La Salle Schools in the Philippines. This yielded over 1300 individual incidents that were compared and contrasted to form codes, categories and subcategories. A theory on the decision making process of helping emerged that incorporates the helper’s personal conviction, and rational deliberations of the situation. The desire to help is based on the helper’s rationalemotive beliefs (philosophical ideals and values that nurture helping and the knowledge of the nature of risk/problem and relational-emotive ties (with the one who needs help and with a social group that nurtures helping. The desire to help undergoes a process of rationalpragmatic-deliberations on the appropriateness of the recipients need of help, the cost of helping, the helper’s capability of helping, and the logistics of helping before the actual helping occurs. The theory has implications for current social psychological theories of helping, and the use of classic grounded theory research.

    The social networking site (SNS) Facebook is becoming increasingly recognized as a medium through which individuals can investigate and monitor others' activities. However, little is known about whether Facebook monitoring behavior occurs within romantic relationships and, accordingly, the psychological predictors of this behavior. The present study employed an extended theory of planned behavior (TPB) framework including self-esteem, partner trust, and demographic characteristics, to predict frequent Facebook partner-monitoring. Facebook users (N=244) in romantic relationships completed measures assessing the standard TPB constructs (attitude, subjective norm, and perceived behavioral control), additional predictor variables (self-esteem and partner trust), and demographic characteristics (age, gender, relationship length, daily Facebook logins, and time spent per login). One week later, participants reported their level of Facebook partner-monitoring during the previous week. Regression analyses supported the standard TPB constructs of attitude and subjective norm in predicting intentions to engage in frequent Facebook partner-monitoring, with intention, in turn, predicting behavior. Partner trust, but not self-esteem, significantly predicted frequent Facebook partner-monitoring intentions. Of the demographic characteristics, daily Facebook logins significantly predicted both intention and behavior and, unexpectedly, relationship length directly affected behavior. Overall, the current study revealed that frequent Facebook partner-monitoring is influenced by attitudinal, normative, and relational factors and, potentially, increased visits to Facebook. These findings provide a new understanding of an individual's use of the world's leading SNS to monitor their partner's activities and provide a foundation for future studies to investigate the potential negative implications this activity may have for those in romantic relationships.

    Extending the formulation for open superstring field theory given in arXiv:1508.00366, we attempt to construct a complete action for heterotic string field theory. The action is non-polynomial in the Ramond string field Psi, and we construct it order by order in Psi. Using a dual formulation in which the role of eta and Q is exchanged, the action is explicitly obtained at the quadratic and quartic order in Psi with the gauge transformations.

    Full Text Available Analysis of market structures is thearea of economics, where game theory has madethe greatest use. On competitive markets with manyparticipants, each participant seeks the bestsolution for himself/herself, ignoring the actions ofother participants. However, if the number ofparticipants is small and each of them has somemarket power, then each participant must take intoaccount the behavior of others. The analysis of suchmarket structures especially reflects the use ofgame theory. This paper analyzes oligopolisticmarket structure and strategic interaction betweenthe participants in this market. The paper considersa few most important models related to differentbehaviors of enterprises in oligopolisticenvironment. It also analyzes how firms inoligopoly can take strategic steps to get anadvantage or a better position relative tocompetitors. The aim of the paper is to examine thepossibility of applying game theory to analyzestrategic actions of companies in oligopolisticmarkets.

    2009-12-01

    Despite the increasing popularity of social networking Web sites (SNWs), very little is known about the psychosocial variables that predict people's use of these Web sites. The present study used an extended model of the theory of planned behavior (TPB), including the additional variables of self-identity and belongingness, to predict high-level SNW use intentions and behavior in a sample of young people ages 17 to 24 years. Additional analyses examined the impact of self-identity and belongingness on young people's addictive tendencies toward SNWs. University students (N = 233) completed measures of the standard TPB constructs (attitude, subjective norm, and perceived behavioral control), the additional predictor variables (self-identity and belongingness), demographic variables (age, gender, and past behavior), and addictive tendencies. One week later, they reported their engagement in high-level SNW use during the previous week. Regression analyses partially supported the TPB: attitude and subjective norm significantly predicted intentions to engage in high-level SNW use with intention significantly predicting behavior. Self-identity, but not belongingness, significantly contributed to the prediction of intention and, unexpectedly, behavior. Past behavior also significantly predicted intention and behavior. Self-identity and belongingness significantly predicted addictive tendencies toward SNWs. Overall, the present study revealed that high-level SNW use is influenced by attitudinal, normative, and self-identity factors, findings that can be used to inform strategies that aim to modify young people's high levels of use or addictive tendencies for SNWs.

  20. Construction of Monte Carlo operators in collisional transport theory

    International Nuclear Information System (INIS)

    A Monte Carlo approach for investigating the dynamics of quiescent collisional magnetoplasmas is presented, based on the discretization of the gyrokinetic equation. The theory applies to a strongly rotating multispecies plasma, in a toroidally axisymmetric configuration. Expressions of the Monte Carlo collision operators are obtained for general v-space nonorthogonal coordinates systems, in terms of approximate solutions of the discretized gyrokinetic equation. Basic features of the Monte Carlo operators are that they fullfill all the required conservation laws, i.e., linear momentum and kinetic energy conservation, and in addition that they take into account correctly also off-diagonal diffusion coefficients. The present operators are thus potentially useful for describing the dynamics of a multispecies toroidal magnetoplasma. In particular, strict ambipolarity of particle fluxes is ensured automatically in the limit of small departures of the unperturbed particle trajectories from some initial axisymmetric toroidal magnetic surfaces

    A less-than-optimal proportion of patients with cancer are entered into National Cancer Institute-sponsored clinical trials. This article reviews the literature on accrual in oncology clinical trials to characterize the extent of the problem, identify reasons for low accrual, and suggest ways to promote accrual. Four well known theories of health behavior (the Health Belief Model, Subjective Expected Utility Theory, Protection Motivation Theory, and the Theory of Reasoned Action) point to central concepts involved in understanding patient health-related behavior: (1) the probability that an unwelcomed health event will happen to a patient, (2) the severity of that event if it does occur, (3) the effectiveness of a particular behavior (such as taking part in a clinical trial) to modify the severity, and (4) the cost of adopting that behavior. These concepts form a framework for integrating the available information about accrual to clinical oncology trials. Patient and physician factors previously related to clinical trials suggest specific recommendations for increasing accrual to clinical oncology trials. PMID:7954285

  5. Applying the Theory of Planned Behavior in Predicting Proenvironmental Behaviour: The Case of Energy Conservation

    Directory of Open Access Journals (Sweden)

    Octav-Ionuţ Macovei

    2015-08-01

    Full Text Available This paper aims to propose and validate a model based on the Theory of Planned Behavior in order to explain consumers’ pro-environmental behaviour regarding energy conservation. The model was constructed using the five variables from Ajzen’s Theory of Planned Behavior (TPB (behaviour, intention, perceived behavioural control, subjective norms and attitude to which a variable adapted from Schwartz’s Norm Activation Theory (NAT was added (“awareness of the consequences and the need” in order to create a unique model adapted for the special case of energy conservation behaviour. Further, a survey was conducted and the data collected were analysed using structural equation modelling. The first step of data analysis confirmed that all the constructs have good reliability, internal consistency and validity. The results of the structural equation analysis validated the proposed model, with all the model fit and quality indices having very good values. In the analysis of consumers’ proenvironmental behaviour regarding energy conservation and their intention to behave in a proenvironmental manner, this model proved to have a strong predictive power. Five of seven hypotheses were validated, the newly introduced variable proving to be a success. The proposed model is unique and will offer companies and organizations a valuable green marketing tool which can be used in the fight for environment protection and energy conservation.

  7. Integrating behavior change theory into geriatric case management practice.

    Enguidanos, S

    2001-01-01

    Case management practices have continued to grow despite a lack of clear evidence of their efficacy. With the expanding segment of the elderly population, there is a critical need to develop and identify programs that will address the many needs of the aging. Geriatric Case Management has been the avenue selected by many health care providers to address these issues, focusing on maintaining health status and improving linkages with medical and community resources. Studies testing the effectiveness of these models have failed to demonstrate their effectiveness in reducing depression, reducing acute care service use, and improving or maintaining health status. The Geriatric Case Management models presented in these lack an evidence-based, theoretical framework that provides definition and direction for case management practice. This article introduces behavior change theories as a method of structuring and delineating the case management intervention. The Transtheoretical Model and the Theory of Planned Behavior are discussed and methods of integrating these theories into practice are discussed. PMID:11878076

  9. Construction of non-critical string field theory by transfer matrix formalism in dynamical triangulation

    International Nuclear Information System (INIS)

    We propose a new method which analyzes the dynamical triangulation from the viewpoint of the non-critical string field theory. By using the transfer matrix formalism, we construct the non-critical string field theory (including c > 1 cases) at the discrete level. For pure quantum gravity, we succeed in taking the continuum limit and obtain the c = 0 non-critical string field theory at the continuous level. We also study about the universality of the non-critical string field theory. (author)

    Higher-derivative corrections to the Einstein-Hilbert action are present in bosonic string theory leading to the potential causality violations recently pointed out by Camanho et al. We analyze in detail this question by considering high-energy string-brane collisions at impact parameters $b \\le l_s$ (the string-length parameter) with $l_s \\gg R_p$ (the characteristic scale of the D$p$-brane geometry). If we keep only the contribution of the massless states causality is violated for a set of initial states whose polarization is suitably chosen with respect to the impact parameter vector. Such violations are instead neatly avoided when the full structure of string theory - and in particular its Regge behavior - is taken into account.

  12. Negative reactions to depressive behaviors: a communication theories analysis.

    Science.gov (United States)

    Segrin, C; Abramson, L Y

    1994-11-01

    Interpersonal aspects of depression have received considerable research attention in the past 2 decades. This work often has been guided by J. C. Coyne's (1976b) interactional model of depression or P. M. Lewinsohn's (1974) social skill deficit theory of depression. A review of this research indicates that depressed people reliably experience rejection from those in their social environment and that depression generally is associated with impairments in social behavior. However, this research does not explain exactly what depressed people do to elicit rejection, or exactly why others react negatively to them. Research derived from communication theories on responsiveness, politeness, and expectations for nonverbal involvement illuminates the interpersonal cycle in depression. The role of these impairments in the cause, symptoms, course, subtypes, and therapy of depression is discussed. PMID:7822566

    2005-01-01

    The Robot Construction Crew (RCC) is a heterogeneous multi-robot system for autonomous construction of a structure through assembly of Long components. The two robot team demonstrates component placement into an existing structure in a realistic environment. The task requires component acquisition, cooperative transport, and cooperative precision manipulation. A behavior-based architecture provides adaptability. The RCC approach minimizes computation, power, communication, and sensing for applicability to space-related construction efforts, but the techniques are applicable to terrestrial construction tasks.

    Wang, Y. K.; Lamb, W. E., Jr.

    1973-01-01

    The transient behavior of a laser is discussed using the quantum theory as did Scully and Lamb. The formal solution of the density-matrix equation is expressed in terms of exponentially decaying eigenmodes. Some of the lower decay constants are obtained numerically. The equations for the moments of the density matrix are then derived and solved by a truncation method. The equations of motion are integrated numerically for the case where the average number of photons in a laser cavity has the realistically large value 1.3 x 100,000. An alternative Fokker-Planck-equation approach is discussed.

  19. Biologically inspired information theory: Adaptation through construction of external reality models by living systems.

    Science.gov (United States)

    Nakajima, Toshiyuki

    2015-12-01

    Higher animals act in the world using their external reality models to cope with the uncertain environment. Organisms that have not developed such information-processing organs may also have external reality models built in the form of their biochemical, physiological, and behavioral structures, acquired by natural selection through successful models constructed internally. Organisms subject to illusions would fail to survive in the material universe. How can organisms, or living systems in general, determine the external reality from within? This paper starts with a phenomenological model, in which the self constitutes a reality model developed through the mental processing of phenomena. Then, the it-from-bit concept is formalized using a simple mathematical model. For this formalization, my previous work on an algorithmic process is employed to constitute symbols referring to the external reality, called the inverse causality, with additional improvements to the previous work. Finally, as an extension of this model, the cognizers system model is employed to describe the self as one of many material entities in a world, each of which acts as a subject by responding to the surrounding entities. This model is used to propose a conceptual framework of information theory that can deal with both the qualitative (semantic) and quantitative aspects of the information involved in biological processes.

  20. Influence of construction concepts on training behavior of gyrotron magnets

    International Nuclear Information System (INIS)

    A series of 60 NbTi gyrotron magnets intended mainly for high frequency plasma heating complexes at Tokamak T-10 and Tokamak T-15, and prototypes and later improved versions for the same applications within ITER project, were developed and tested. A variety of constructional and technological concepts was applied. As a result of empirical experience in parallel with the application of established theoretical models to the magnet development, a remarkable improvement in winding mechanical stability was reached. The differences in magnet winding construction are related to operational as well as training and quench behaviour. (Author)

    Game theory is central to understanding human behavior and relevant to all of the behavioral sciences-from biology and economics, to anthropology and political science. However, as The Bounds of Reason demonstrates, game theory alone cannot fully explain human behavior and should instead complement other key concepts championed by the behavioral disciplines. Herbert Gintis shows that just as game theory without broader social theory is merely technical bravado, so social theory without game theory is a handicapped enterprise. This edition has been thoroughly revised and updated. Reinvigorati

  6. View from Behavioral Economics Theory: Case of Latvian Rural Entrepreneurs

    Directory of Open Access Journals (Sweden)

    Igo Cals

    2013-11-01

    Full Text Available The theory of classical economics treats entrepreneurs as subjects who make rational economic decisions. Empirical surveys prove the fact that daily economic decisions made by a separate economic entity can be explained by concepts of behavioral economics rather than classical economics. The economic behavior of entrepreneurs happens to be based on bounded rationality instead of financial justification. The objective of an economic activity presented as economically efficient can turn out to be socially important to a specific entrepreneur and not to national economy as a whole. In the EU countries, agriculture is a subsidised industry of national economy. In this light, status consumption and purchase of positional goods should create a special interest among economists. The objective of this article is to present true reasons of economic decisions made by rural entrepreneurs and to analyse the value hierarchy of Latvian rural entrepreneurs through carrying out a field work and with the help of set of instruments developed by modern economics theory.

  7. Geometry and construction. Theory of principal curvature lines in stone stereotomy

    Directory of Open Access Journals (Sweden)

    Federico Fallavollita

    2012-06-01

    Full Text Available The paper illustrates the theoretical and practical study of the theory of curvature lines elaborated by Gaspard Monge at the end of the eighteenth century, and its application to the construction of cut stone architecture, with particular reference to the specific case study of an ellipsoidal vault (proposed by Monge and revisited by Hachette and Leroy. The intent is to optimize the construction of these lines in the method of the mathematical representation, at least for the case study. The link that exists between the theories of descriptive geometry and the stereotomic design principles is significant. Theoretical geometric constructions, seemingly abstract, are applied in the practice of construction and become, at times, a prerequisite to solving complex cases such as that presented.

  8. Intentions and willingness to drive while drowsy among university students: An application of an extended theory of planned behavior model.

    Science.gov (United States)

    Lee, Clark J; Geiger-Brown, Jeanne; Beck, Kenneth H

    2016-08-01

    A web-based questionnaire was used to assess the utility of constructs from the Theory of Planned Behavior (TPB) and the Prototype Willingness Model (PWM) to predict intentions and willingness to engage in drowsy driving in a sample of 450 university students. Those students who reported more favorable attitudes and subjective norm and greater perceived control and willingness in relation to drowsy driving behavior were more likely to report stronger intentions to engage in drowsy driving behavior. Augmenting the TPB constructs with the PWM construct of willingness significantly explained up to an additional 8 percent of the variance in drowsy driving intention. Perceived behavioral control and willingness were consistently the strongest predictors of drowsy driving intention in the augmented model, which together with the control (personal) variables explained up to 70 percent of the variance in intention. Thus, the Theory of Planned Behavior and the Prototype Willingness Model may be useful for understanding motivational influences on drowsy driving behavior in young people and present promising theoretical frameworks for designing more effective interventions against drowsy driving in this population.

  16. Construction and Borel summability of planar 4-dimensional Euclidean field theory

    International Nuclear Information System (INIS)

    We use methods to show that the planar part of the renormalized perturbation theory for phi44-euclidean field theory is Borel-summable on the asymptotically free side of the theory. The Borel sum can therefore be taken as a rigorous definition of the N->infinite limit of a massive NxN matrix model with a+trgphi4 interaction, hence with ''wrong sign'' of g. Our construction is essentially equivalent to a solution of the ultra-violet problem for planar QCD. We also propose a program for studying the structure of the ''renormalons'' singularities within the planar world. (orig.)

    2015-01-01

    In this paper, we construct novel Drukker-Trancanelli (DT) type BPS Wilson loops along infinite straight lines in $\\mathcal N=2,3$ quiver super Chern-Simons-matter (CSM) theories, Aharony-Bergman-Jafferis-Maldacena (ABJM) theory, and $\\mathcal N=4$ orbifold ABJM theory. There are several free complex parameters in the DT type BPS Wilson loops, and for Wilson loops in ABJM theory and $\\mathcal N=4$ orbifold ABJM theory there are supersymmetry enhancements at special values of the parameters. We check that the differences of the DT type and Gaiotto-Yin (GY) type Wilson loops are $Q$-exact with $Q$ being some supercharges preserved by both the DT type and GY type Wilson loops. The results would be useful to calculate vacuum expectation values of the Wilson loops in matrix models if they are still BPS quantum mechanically.

  19. On the construction of quantum field theories with factorizing S-matrices

    International Nuclear Information System (INIS)

    The subject of this thesis is a novel construction method for interacting relativistic quantum field theories on two-dimensional Minkowski space. Employing the algebraic framework of quantum field theory, it is shown under which conditions an algebra of observables localized in a wedge-shaped region of spacetime can be used to construct model theories. A crucial input in this context is the modular nuclearity condition for wedge algebras, which implies the existence of local observables. As an application of the new method, a rigorous construction of a large family of models with factorizing S-matrices is obtained. In an inverse scattering approach, a given factorizing scattering operator is used to define certain semi-localized Wightman fields associated to it. With the help of these fields, a wedge algebra can be defined, which determines the local observable content of a well-defined quantum field theory. In this approach, the modular nuclearity condition translates to certain analyticity and boundedness conditions on the formfactors of wedge-local observables. These conditions are shown to hold for a large class of underlying S-matrices, including the scattering operators of the Sinh-Gordon model and the scaling Ising model as special examples. The so constructed models are investigated with respect to their scattering properties. They are shown to solve the inverse scattering problem for the underlying S-matrices, and a proof of asymptotic completeness for these models is given. (orig.)

    Full Text Available In Malaysia, according to road accidents data statistics motorcycle users contributes more than 50% of fatalities in traffic accidents, and the major cause due to head injuries. One strategy that can be used to reduce the severity of head injuries is by proper usage of helmet. Although the safety helmet is the best protective equipment to prevents head injury, majority motorcycle user did not use or did not fasten properly. In understanding this problem, the behavioral sciences theory and engineering aspect are needed to provide better explanation and comprehensive insights into solutions. The Theory Planned Behavior (TPB and Health Belief Model (HBM were used in predicting the behavioral intention toward proper helmet usage among motorcyclist. While, a new intervention approach were used in Technology Acceptance Model (TAM that based on the perception of a conceptual system called Safety Helmet Reminder System (SHR. Results show that the constructs variables are reliable and statistically significant with the exogenous and endogenous variables. The full structured models were proposed and tested, thus the significant predictors were identified. A multivariate analysis technique, known as Structural Equation Model (SEM was used in modeling exercise.  Finally, the good-of-fit models were used in interpreting the implication of intervention strategy toward motorcyclist injury prevention program.

    2013-01-01

    Full Text Available Selecting construction schemes of the building engineering project is a complex multiobjective optimization decision process, in which many indexes need to be selected to find the optimum scheme. Aiming at this problem, this paper selects cost, progress, quality, and safety as the four first-order evaluation indexes, uses the quantitative method for the cost index, uses integrated qualitative and quantitative methodologies for progress, quality, and safety indexes, and integrates engineering economics, reliability theories, and information entropy theory to present a new evaluation method for building construction project. Combined with a practical case, this paper also presents detailed computing processes and steps, including selecting all order indexes, establishing the index matrix, computing score values of all order indexes, computing the synthesis score, sorting all selected schemes, and making analysis and decision. Presented method can offer valuable references for risk computing of building construction projects.

  9. Systematicity and a Categorical Theory of Cognitive Architecture: Universal Construction in Context

    2016-01-01

    Why does the capacity to think certain thoughts imply the capacity to think certain other, structurally related, thoughts? Despite decades of intensive debate, cognitive scientists have yet to reach a consensus on an explanation for this property of cognitive architecture—the basic processes and modes of composition that together afford cognitive capacity—called systematicity. Systematicity is generally considered to involve a capacity to represent/process common structural relations among the equivalently cognizable entities. However, the predominant theoretical approaches to the systematicity problem, i.e., classical (symbolic) and connectionist (subsymbolic), require arbitrary (ad hoc) assumptions to derive systematicity. That is, their core principles and assumptions do not provide the necessary and sufficient conditions from which systematicity follows, as required of a causal theory. Hence, these approaches fail to fully explain why systematicity is a (near) universal property of human cognition, albeit in restricted contexts. We review an alternative, category theory approach to the systematicity problem. As a mathematical theory of structure, category theory provides necessary and sufficient conditions for systematicity in the form of universal construction: each systematically related cognitive capacity is composed of a common component and a unique component. Moreover, every universal construction can be viewed as the optimal construction in the given context (category). From this view, universal constructions are derived from learning, as an optimization. The ultimate challenge, then, is to explain the determination of context. If context is a category, then a natural extension toward addressing this question is higher-order category theory, where categories themselves are the objects of construction. PMID:27524975

    Full Text Available Christine L Hackman, Adam P KnowldenDepartment of Health Science, The University of Alabama, Tuscaloosa, AL, USABackground: Childhood obesity has reached epidemic proportions in many nations around the world. The theory of planned behavior (TPB and the theory of reasoned action (TRA have been used to successfully plan and evaluate numerous interventions for many different behaviors. The aim of this study was to systematically review and synthesize TPB and TRA-based dietary behavior interventions targeting adolescents and young adults.Methods: The following databases were systematically searched to find articles for this review: Academic Search Premier; Cumulative Index to Nursing and Allied Health (CINAHL; Education Resources Information Center (ERIC; Health Source: Nursing/Academic Edition; Cochrane Central Register of Controlled Trials (CENTRAL; and MEDLINE. Inclusion criteria for articles were: 1 primary or secondary interventions, 2 with any quantitative design, 3 published in the English language, 4 between January 2003 and March 2014, 5 that targeted adolescents or young adults, 6 which included dietary change behavior as the outcome, and 7 utilized TPB or TRA.Results: Of the eleven intervention studies evaluated, nine resulted in dietary behavior change that was attributed to the treatment. Additionally, all but one study found there to be a change in at least one construct of TRA or TPB, while one study did not measure constructs. All of the studies utilized some type of quantitative design, with two employing quasi-experimental, and eight employing randomized control trial design. Among the studies, four utilized technology including emails, social media posts, information on school websites, web-based activities, audio messages in classrooms, interactive DVDs, and health-related websites. Two studies incorporated goal setting and four employed persuasive communication.Conclusion: Interventions directed toward changing dietary behaviors

    Impulsivity, often defined as a human behavior characterized by the inclination of an individual to act on urge rather than thought, with diminished regard to consequences, encompasses a range of maladaptive behaviors which are in turn affected by distinct neural systems. Congruent with the above definition, behavioral studies have consistently shown that the underlying construct of impulsivity is multidimensional in nature. However, research to date has been inconclusive regarding the differ...

    2013-01-01

    The current study investigated sexual initiations within the framework of the Theory of Planned Behavior (TPB) (Ajzen, 1991; Ajzen & Madden, 1986). Male and female daters in heterosexual dating relationships completed an online survey that assessed their sexual relationship with their partner and the TPB components (perceptions of social norms, attitudes, perceived behavioral control, and intentions). The TPB was supported for both men and women in that, as predicted, the more an individual perceived that important others would approve of them initiating sexual activities with their partner, the more positive their evaluations were of the outcomes of initiating, and the more confident they were in their ability to initiate, the stronger were their initiation intentions. In turn, stronger sexual initiation intentions were associated with more frequent initiation behaviors. Compared to women, men initiated more frequently, had stronger sexual initiation intentions, and perceived more positive social norms regarding initiation; men and women did not differ in their attitudes toward sexual initiation or in their perceived behavioral control. Both men and women who reported initiating more frequently and perceived their partner as initiating more frequently reported greater sexual satisfaction. These results are discussed in terms of the utility of the TPB for understanding sexual initiations and the role of the traditional sexual script in initiation-related cognitions and behavior.

    Full Text Available Among millions of people who suffer from schistosomiasis in China, adolescents are at increased risk to be infected. However, there is a lack of theory-guided behavioral prevention intervention programs to protect these adolescents. This study attempted to apply the Protection Motivation Theory (PMT in predicting intentions to engage in protective behaviors against schistosomiasis infection.The participants were selected using the stratified cluster sampling method. Survey data were collected using anonymous self-reported questionnaire. The advanced structural equation modeling (SEM method was utilized to assess the complex relationship among schistosomiasis knowledge, previous risk exposure and protective measures in predicting intentions to engage in protective behavior through the PMT constructs.Approximately 70% of participants reported they were always aware of schistosomiasis before exposure to water with endemic schistosomiasis, 6% of the participants reported frequency of weekly or monthly prior exposure to snail-conditioned water. 74% of participants reported having always engaged in protective behaviors in the past three months. Approximately 7% were unlikely or very unlikely to avoid contact with snail-conditioned water, and to use protective behaviors before exposure. Results from SEM analysis indicated that both schistosomiasis knowledge and prior exposure to schistosomiasis were indirectly related to behavior intentions through intrinsic rewards and self-efficacy; prior protective behaviors were indirectly related to behavior intentions through severity, intrinsic rewards and self-efficacy, while awareness had an indirect relationship with behavior intentions through self-efficacy. Among the seven PMT constructs, severity, intrinsic rewards and self-efficacy were significantly associated with behavior intentions.The PMT can be used to predict the intention to engage in protective behaviors against schistosomiasis.

    2014-01-01

    The present research adopts an extended theory of the planned behavior model that included descriptive norms, risk, and trust to investigate online privacy protection in Facebook users. Facebook users (N = 119) completed a questionnaire assessing their attitude, subjective injunctive norm, subjective descriptive norm, perceived behavioral control, implicit perceived risk, trust of other Facebook users, and intentions toward protecting their privacy online. Behavior was measured indirectly 2 weeks after the study. The data show partial support for the theory of planned behavior and strong support for the independence of subjective injunctive and descriptive norms. Risk also uniquely predicted intentions over and above the theory of planned behavior, but there were no unique effects of trust on intentions, nor of risk or trust on behavior. Implications are discussed. PMID:25154118

    Bohm, Jonathan; Harris, Don

    2010-01-01

    In the UK construction site dumpers cause more serious accidents than any other type of construction plant. Previous research has indicated that driver behavior plays a pivotal role in the vast majority of these accidents. This study used a paired comparison technique to explore dumper drivers' and subject matter experts' (SMEs') risk perception and its relationship to risk-taking behavior. It was found that driver risk perception significantly differed from measures of "objective risk", derived from accident data and also from SMEs' risk perception. Furthermore, drivers still engaged in undertaking perceived high risk behaviors. The results suggest that driver risk perception was linked to the "perceived dread" of an accident, rather than its likelihood and that risk-taking behavior was often driven by situational factors, such as site safety rules or the behavior of other personnel on the site, together with an overarching culture that prioritizes production over safety.

    We present a simple numerical scheme for perturbation theory (PT) calculations of large-scale structure. Solving the evolution equations for perturbations numerically, we construct the PT kernels as building blocks of statistical calculations, from which the power spectrum and/or correlation function can be systematically computed. The scheme is especially applicable to the generalized structure formation including modified gravity, in which the analytic construction of PT kernels is intractable. As an illustration, we show several examples for power spectrum calculations in $f(R)$ gravity and $\\Lambda$CDM models.

    2015-05-01

    We construct a series of bbosonic-symmetry-protected topological (BSPT) states beyond group cohomology classification using "decorated defects" approach. This construction is based on topological defects of ordinary Landau order parameters, decorated with the bosonic short-range entangled (BSRE) states in (4 k +3 )d and (4 k +5 )d space-time (with k being nonnegative integers), which do not need any symmetry. This approach not only gives these BSPT states an intuitive physical picture, it also allows us to derive the effective field theory for all these BSPT states beyond group cohomology.

  4. Complete construction of magical, symmetric and homogeneous N=2 supergravities as double copies of gauge theories

    Chiodaroli, Marco; Johansson, Henrik; Roiban, Radu

    2015-01-01

    We show that scattering amplitudes in magical, symmetric or homogeneous N=2 Maxwell-Einstein supergravities can be obtained as double copies of two gauge theories, using the framework of color/kinematics duality. The left-hand-copy is N=2 super-Yang-Mills theory coupled to a hypermultiplet, whereas the right-hand-copy is a non-supersymmetric theory that can be identified as the dimensional reduction of a D-dimensional Yang-Mills theory coupled to P fermions. For generic D and P, the double copy gives homogeneous supergravities. For P=1 and D=7,8,10,14, it gives the magical supergravities. We compute explicit amplitudes, discuss their soft limit and study the UV-behavior at one loop.

    Full Text Available Introduction: One of the basics of healthy eating is five times consumption of fruits and vegetable a day. Given the importance of recognizing effective factors of consuming fruit and vegetable in this group, the present study aimed to investigate high school girl's adherence to five-time serving fruits and vegetables per day in Hamadan based on the theory of planned behavior application. Materials and Methods: This descriptive-analytical study was performed on 400 girl students from high schools of Hamadan recruited with a multistage cluster sampling method. Participants filled out questionnaires including demographic variables, the theory of planned behavior constructs and a fruit and vegetable consumption measure one week later. Data analysis was performed using SPSS-18 by Chi-square, Pearson correlation and Logistic regression. Results: Fruit and vegetable consumption by female students is 3.4 times daily. Among the demographic variables, family size, mother's education, father's occupation, household income, body mass index and type of school had significant associations with fruit and vegetable consumption (P<0.05. Behavioral intention predicted 35% of the variation in daily fruit and vegetable consumption. Moreover, subjective norms, perceived behavioral control and attitude were able to predict 32% of behavioral intention. Conclusion: Fruit and vegetable consumption in female students is inadequate. The theory of planned behavior may be a useful framework to design a 5-A-Day intervention for female students.

    Science.gov (United States)

    Yang, Tangfeng

    2016-04-01

    Cognitive linguists claim that verb-particle constructions are compositional and analyzable, and that the particles contribute to the overall meaning in the form of image schemas. This article examined this claim with a behavioral experiment, in which participants were asked to judge the sensibility of short sentences primed by image-schematic pictures. Results showed that for sentences containing spatial VP constructions, the latency followed the order of "agreement primes [Formula: see text] neutral primes [Formula: see text] disagreement primes", while for sentences of non-spatial VP constructions, the order was "neutral primes [Formula: see text] agreement primes [Formula: see text] disagreement primes". This suggests that the activation of the corresponding image schemas influences both types of VP constructions, providing new evidence for the embodied account of language and thought. The different processing patterns between the spatial and non-spatial VP constructions are also discussed in the theoretical framework of Construction Grammar. PMID:25708965

  10. From constructive field theory to fractional stochastic calculus. (I) An introduction: rough path theory and perturbative heuristics

    CERN Document Server

    2010-01-01

    Let $B=(B_1(t),..,B_d(t))$ be a $d$-dimensional fractional Brownian motion with Hurst index $\\alpha\\le 1/4$, or more generally a Gaussian process whose paths have the same local regularity. Defining properly iterated integrals of $B$ is a difficult task because of the low H\\"older regularity index of its paths. Yet rough path theory shows it is the key to the construction of a stochastic calculus with respect to $B$, or to solving differential equations driven by $B$. We intend to show in a forthcoming series of papers how to desingularize iterated integrals by a weak singular non-Gaussian perturbation of the Gaussian measure defined by a limit in law procedure. Convergence is proved by using "standard" tools of constructive field theory, in particular cluster expansions and renormalization. These powerful tools allow optimal estimates of the moments and call for an extension of the Gaussian tools such as for instance the Malliavin calculus. This first paper aims to be both a presentation of the basics of rou...

    Background Despite evidence of the benefits of exercise in cancer survivors, exercise participation rates tend to decline after treatments. Few studies have examined the determinants of exercise in less common cancer sites. In this study, we examined medical, demographic, and social cognitive correlates of exercise in endometrial cancer survivors using the Theory of Planned Behavior (TPB). Methods A mailed survey was completed by 354 endometrial cancer survivors (1 to 10 years postdiagnosis) residing in Alberta, Canada. The study was cross-sectional. Exercise behavior was assessed using the Godin Leisure Time Exercise Questionnaire and the TPB constructs were assessed with standard self-report scales. Multiple regression analyses were used to determine the independent associations of the TPB constructs with intention and behavior. Results Chi-square analyses indicated that marital status (p = .003), income level (p = .013), and body mass index (BMI) (p = .020) were associated with exercise. The TPB explained 34.1% of the variance in exercise behavior with intention (β = .38, p TPB with self-efficacy (β = .34, p TPB mediated the associations of marital status and BMI with exercise but not income level. Age and BMI moderated the associations of the TPB with intention and behavior. Conclusion The TPB may be a useful framework for understanding exercise in endometrial cancer survivors. Exercise behavior change interventions based on the TPB should be tested in this growing population. PMID:17537255

    2015-06-01

    We calculate fermionic Green's functions for states of the three-dimensional Aharony-Bergman-Jafferis-Maldacena M2-brane theory at large N using the gauge-gravity correspondence. We embed extremal black brane solutions in four-dimensional maximally supersymmetric gauged supergravity, obtain the linearized Dirac equations for each spin-1 /2 mode that cannot mix with a gravitino, and solve these equations with infalling boundary conditions to calculate retarded Green's functions. For generic values of the chemical potentials, we find Fermi surfaces with universally non-Fermi liquid behavior, matching the situation for four-dimensional N =4 super-Yang-Mills. Fermi surface singularities appear and disappear discontinuously at the point where all chemical potentials are equal, reminiscent of a quantum critical point. One limit of parameter space has zero entropy at zero temperature, and fermionic fluctuations are perfectly stable inside an energy region around the Fermi surface. An ambiguity in the quantization of the fermions is resolved by supersymmetry.

    2006-12-01

    The purpose of this study was to create a theory of women's career choice and development in the context of the construction industry. Focused on female constructors, or those engaged in the management of construction projects or companies, this study investigated the relevant factors, processes, and experiences of women who choose to enter the construction industry through construction management degree programs. The goal was to communicate as a theoretically and practically grounded theory of career choice and development an understanding of who female constructors are and those factors which led them to the construction industry and those influencing their career development. As a grounded theory research design, qualitative research methods were employed as the primary means of collecting and analyzing data. Purposive and snowball sampling were used to garner a sample of 24 women who had graduated within a ten year period and were actively employed as constructors. Participants' views and experiences, captured through small focus group interviews, were analyzed with quantitative data of demographics, education, construction experience, self-efficacy, personality, and career satisfaction and commitment gathered from a written questionnaire, to create a profile of female constructors used in this theory. The profiles completed from these data are complex, providing for an extensive understanding of their career choice and development process. The strongest common characteristic in the career development of these women was a mentor. This influence in cannot be overlooked, especially in light of the rather constant sense of isolation many of these women expressed as a significant minority in every facet of their careers. Recommendations for academia and industry are in many ways related to these findings. Recommendations for recruitment center on educating youth and those able to influence the career choice making process of youth about the career paths available

    Reise, S P; Rodriguez, A

    2016-07-01

    Item response theory (IRT) measurement models are now commonly used in educational, psychological, and health-outcomes measurement, but their impact in the evaluation of measures of psychiatric constructs remains limited. Herein we present two, somewhat contradictory, theses. The first is that, when skillfully applied, IRT has much to offer psychiatric measurement in terms of scale development, psychometric analysis, and scoring. The second argument, however, is that psychiatric measurement presents some unique challenges to the application of IRT - challenges that may not be easily addressed by application of conventional IRT models and methods. These challenges include, but are not limited to, the modeling of conceptually narrow constructs and their associated limited item pools, and unipolar constructs where the expected latent trait distribution is highly skewed.

    Full Text Available Introduction & Objective: Driving under the influence of drugs is considered a social pathology that has adverse effects on a society. This study aimed to investigate the effect of substance abuse educational program among the bus drivers on the basis of the theory of planned be-havior. Materials & Methods: This quasi-experimental study was conducted on 80 suburban bus drivers working at Hamadan transportation terminal. The bus drivers were randomly divided in two equal groups (intervention and control. Intervention program design was implemented after diagnostic evaluation. The effect of educational intervention on behavior was assessed two months after the last training session. SPSS -16 was employed for data analysis. Results: After the educational intervention, the average rates of the constructs of the theory of planned behavior in the intervention group significantly increased but these changes were not significant in the control group: attitude (t=9.53, P=0.000, subjective Norms (t=9.59, P=0.000, perceived behavioral control (t=-4.14, P =0.000. Also, behavioral intention to substance abuse avoidance and current behavior for substance abuse significantly decreased in the intervention group as compared to the control group (P<0.05. Behavioral intention and current behavior in the intervention group subsided from 15 and 12 people before the educational intervention to 3 and 0 people at the end of the educational program, respec-tively. Conclusion: The results showed that using the theory of planned behavior along with the train-ing skills strategies to resist drug abuse has a significant impact to create a psychiatric immu-nization and substance refusal in drivers.

    2015-01-01

    The aim of this cross-sectional study was to use social cognitive theory to predict overweight and obesity behaviors in adolescent girls in Iran. Valid and reliable questionnaires about nutritional and physical activity regarding social cognitive theory constructs (self-efficacy, social support, outcome expectations, and outcome expectancies), dietary habits, and physical activity were filled by 172 overweight and obese girl adolescents. The mean age and body mass index were 13.4 ± 0.6 years and 28.2 ± 3.6 kg/m(2), respectively. Body mass index was significantly related to hours of television viewing (p = .003) and grams of junk food (p = .001). None of the social cognitive theory constructs were found to be significant predictors for servings of fruits and vegetables, grams of junk foods, minutes of physical activity, and hours of sedentary behaviors. In future, more culturally appropriate models need to be developed in Iran that can explain and predict prevention behaviors of obesity in Iranian adolescents. PMID:25856805

    Field theories whose full action is Lorentz invariant (or diffeomorphism invariant) can exhibit superluminal behaviors through the breaking of local Lorentz invariance. Quantum induced superluminal velocities are well-known examples of this effect. The issue of the causal behavior of such propagations is somewhat controversial in the literature and we intend to clarify it. We provide a careful analysis of the meaning of causality in classical relativistic field theories, and we stress the rol...

    Full Text Available Abstract Background Despite evidence of the benefits of exercise in cancer survivors, exercise participation rates tend to decline after treatments. Few studies have examined the determinants of exercise in less common cancer sites. In this study, we examined medical, demographic, and social cognitive correlates of exercise in endometrial cancer survivors using the Theory of Planned Behavior (TPB. Methods A mailed survey was completed by 354 endometrial cancer survivors (1 to 10 years postdiagnosis residing in Alberta, Canada. The study was cross-sectional. Exercise behavior was assessed using the Godin Leisure Time Exercise Questionnaire and the TPB constructs were assessed with standard self-report scales. Multiple regression analyses were used to determine the independent associations of the TPB constructs with intention and behavior. Results Chi-square analyses indicated that marital status (p = .003, income level (p = .013, and body mass index (BMI (p = .020 were associated with exercise. The TPB explained 34.1% of the variance in exercise behavior with intention (β = .38, p β = .18, p = .029 being independent correlates. For intention, 38.3% of the variance was explained by the TPB with self-efficacy (β = .34, p β = .30, p Conclusion The TPB may be a useful framework for understanding exercise in endometrial cancer survivors. Exercise behavior change interventions based on the TPB should be tested in this growing population.

However, nosignificant difference was observed in the control group. Conclusion: Regarding the positive effect of education based on The Theory of Planned Behavior in controlling hypertension, planning of a curriculum  based on this theory is recommended.

  2. Theory-based behavior change interventions: comments on Hobbis and Sutton.

    Science.gov (United States)

    Fishbein, Martin; Ajzen, Icek

    2005-01-01

    Hobbis and Sutton (this issue) suggest that Cognitive Behavior Therapy (CBT) techniques can be used in interventions based on the Theory of Planned Behavior (TPB). Although this suggestion has merit, CBT is only one of many applicable methods for producing belief and behavior change. Moreover, CBT's primary purpose is to help people carry out intended behaviors, not to influence intentions, and that it is more useful in face-to-face than in community-level interventions. Contrary to Hobbis and Sutton's critique, TPB can accommodate core beliefs or fundamental assumptions, but the theory suggests that interventions targeted at such beliefs are less effective than interventions targeted at behavior specific beliefs.

  3. Deformations of quantum field theories and the construction of interacting models

    International Nuclear Information System (INIS)

    The subject of this thesis is the rigorous construction of quantum field theoretic models with nontrivial interaction. For this task techniques available in the framework of Algebraic Quantum Field Theory are applied and two different approaches are discussed. On the one hand, an inverse scattering problem is considered. A given scattering matrix is thereby taken as the starting point of the construction. In two spacetime dimensions one may work with factorizing scattering matrices which exhibit a simple structure. The particle spectrum taken into account involves an arbitrary number of massive particle species which transform under some global gauge group. It is a known fact that auxiliary fields with weakened localization, namely in wedges, can be constructed. In the main part of this thesis the more involved transition to local theories is shown by means of operator algebraic methods. Concretely, we make use of the so-called modular nuclearity condition. To this end, we investigate certain maps from the wedge algebras, generated by the auxiliary fields, to the considered Hilbert space. Under a very plausible conjecture it is shown that these maps are nuclear, which implies the nontriviality of algebras associated with bounded regions in the sense that the Reeh-Schlieder property holds. This construction method yields a large class of integrable models with factorizing S-matrices in two spacetime dimensions, complying with localization in bounded regions above a minimal size. The constructed family contains, for example, the multifaceted O(N)-invariant nonlinear sigma-models. On the other hand, deformation techniques constitute a method of construction which may be applied in arbitrary spacetime dimensions. This approach starts from a known quantum field theoretic model which is subjected to a certain modification. Here, concretely, the model of a scalar massive Fermion was deformed. It is shown that the correspondingly emerging models are based on fields with

  4. Integration of Theory of Planned Behavior and Norm Activation Model on Student Behavior Model Using Cars for Traveling to Campus

    Directory of Open Access Journals (Sweden)

    Setiawan, R.

    2014-01-01

    Full Text Available Although there are clear environmental, economic, and social drawbacks in using private vehicles, students still choose cars to get to campus. This study reports an investigation of psychological factors influencing this behavior from the perspective of the Theory of Planned Behavior and Norm Activation Model. Students from three different university campuses in Surabaya, Indonesia, (n = 312 completed a survey on their car commuting behavior. Results indicated that perceived behavioral control and personal norm were the strongest factors that influence behavioral intention. Attitude, subjective norm, perceived behavioral control, and personal norm explain 62.7% variance of the behavioral intention. In turn, behavioral intention explains 42.5% of the variance of the actual car use. Implications of these findings are that in order to alter the use of car, university should implement both structural and psychological interventions. Effective interventions should be designed to raise the awareness of negative aspects of car use.

  7. Reliability of a tool for measuring theory of planned behaviour constructs for use in evaluating research use in policymaking

    Science.gov (United States)

    2011-01-01

    Background Although measures of knowledge translation and exchange (KTE) effectiveness based on the theory of planned behavior (TPB) have been used among patients and providers, no measure has been developed for use among health system policymakers and stakeholders. A tool that measures the intention to use research evidence in policymaking could assist researchers in evaluating the effectiveness of KTE strategies that aim to support evidence-informed health system decision-making. Therefore, we developed a 15-item tool to measure four TPB constructs (intention, attitude, subjective norm and perceived control) and assessed its face validity through key informant interviews. Methods We carried out a reliability study to assess the tool's internal consistency and test-retest reliability. Our study sample consisted of 62 policymakers and stakeholders that participated in deliberative dialogues. We assessed internal consistency using Cronbach's alpha and generalizability (G) coefficients, and we assessed test-retest reliability by calculating Pearson correlation coefficients (r) and G coefficients for each construct and the tool overall. Results The internal consistency of items within each construct was good with alpha ranging from 0.68 to alpha = 0.89. G-coefficients were lower for a single administration (G = 0.34 to G = 0.73) than for the average of two administrations (G = 0.79 to G = 0.89). Test-retest reliability coefficients for the constructs ranged from r = 0.26 to r = 0.77 and from G = 0.31 to G = 0.62 for a single administration, and from G = 0.47 to G = 0.86 for the average of two administrations. Test-retest reliability of the tool using G theory was moderate (G = 0.5) when we generalized across a single observation, but became strong (G = 0.9) when we averaged across both administrations. Conclusion This study provides preliminary evidence for the reliability of a tool that can be used to measure TPB constructs in relation to research use in policymaking

    2012-01-01

    We construct energy independent but non-local potentials above inelastic thresholds, in terms of Nambu-Bethe-Salpeter wave functions defined in quantum field theories such as QCD. As an explicit example, we consider NN --> NN + n pi scattering processes for n=0,1,2,.... We show an existence of energy-independent coupled channel potentials with a non-relativistic approximation, where momenta of all particles are small compared with their own masses. In the case of two-body inelastic scatterings such as Lambda Lambda --> Lambda Lambda, N Xi, Sigma Sigma, on the other hand, we show that energy-independent potentials can be constructed without relying on non-relativistic approximations. We also propose a method to extract these potentials using time-dependence of general correlation functions.

    To provide a unified theoretical framework ranging from a cellular-level excitation mechanism to organic-level geometric propagation, a new theory inspired by quantum electrodynamic theory for light propagation is proposed by describing the cardiac excitation propagation as the continuation of absorption and emission of charged ions by myocardial cells. By the choice of gauge and the membrane current density, a set of Maxwell's equations with a charge density and a current density is constructed in macroscopic bidomain and is shown to be equivalent to the diffusion-reaction system with the B. van der Pol oscillator. The derived Maxwell's equations for the excitation propagation obeys the conservational laws of the number of the cations, energy and momentum, but the total charge is not conserved. The Lagrangian is derived to reveal that the trajectory and wavefront of the excitation propagation are the same as the electrodynamic wave if ion channels work uniformly. From the second quantization, the Hamiltonian...

    2013-01-01

    The aim of this thesis is to develop the dimension theory of self-affine carpets in several directions. Self-affine carpets are an important class of planar self-affine sets which have received a great deal of attention in the literature on fractal geometry over the last 30 years. These constructions are important for several reasons. In particular, they provide a bridge between the relatively well-understood world of self-similar sets and the far from understood world of general self-affi...

  19. A hybrid simulation approach for integrating safety behavior into construction planning: An earthmoving case study.

    Science.gov (United States)

    Goh, Yang Miang; Askar Ali, Mohamed Jawad

    2016-08-01

    One of the key challenges in improving construction safety and health is the management of safety behavior. From a system point of view, workers work unsafely due to system level issues such as poor safety culture, excessive production pressure, inadequate allocation of resources and time and lack of training. These systemic issues should be eradicated or minimized during planning. However, there is a lack of detailed planning tools to help managers assess the impact of their upstream decisions on worker safety behavior. Even though simulation had been used in construction planning, the review conducted in this study showed that construction safety management research had not been exploiting the potential of simulation techniques. Thus, a hybrid simulation framework is proposed to facilitate integration of safety management considerations into construction activity simulation. The hybrid framework consists of discrete event simulation (DES) as the core, but heterogeneous, interactive and intelligent (able to make decisions) agents replace traditional entities and resources. In addition, some of the cognitive processes and physiological aspects of agents are captured using system dynamics (SD) approach. The combination of DES, agent-based simulation (ABS) and SD allows a more "natural" representation of the complex dynamics in construction activities. The proposed hybrid framework was demonstrated using a hypothetical case study. In addition, due to the lack of application of factorial experiment approach in safety management simulation, the case study demonstrated sensitivity analysis and factorial experiment to guide future research.

  20. Construction of scales to measure leadership behavior at nuclear power plants. 1

    International Nuclear Information System (INIS)

    In order to construct scales to measure leadership behavior of managers and supervisors at nuclear power plants, we prepared questionnaire covering all the leadership behaviors of leaders and then had their subordinates fill out the questionnaire. We selected questionnaire items for use in measuring leadership behaviors, analyzing the responses by means of factor analysis, etc. For the section chiefs, five factors were named, i.e., 'consideration' and 'self-righteousness' that belong to group maintenance behavior and 'thorough dissemination of information', 'specialty, planning' and 'pressure' that belong to goal achievement behavior. For the maintenance subsection chiefs were found seven factors, i.e., 'example setting', 'appropriate handling of work', 'planning', 'rigidity', 'educational guidance' that belong to goal achievement behavior and 'consideration for work' and 'personal consideration' that belong to group maintenance behavior. For maintenance and repair foremen were named six factors, i.e., 'consideration' that belongs to group maintenance behavior and 'specialty, planning', 'reporting, liaison', 'adjustment, rigidity', 'paper work confirmation', and 'example setting' that belong to goal achievement behavior. For subcontractors' field leaders were named seven factors, i.e., 'example setting, specialty and planning', 'careful guidance', 'rigidity', 'observance of rules' and 'paper work handling' that belong to goal achievement behavior and, 'consideration', 'frank communication'. In order to examine the validity of these items, we analyzed relationship between the 'morale'-(satisfaction, etc.) variables of the company's regular employees and subcontractors' employees and their leadership. It was found that the three leadership behavior scales for the section chiefs, maintenance and repair subsection chiefs and subcontractor leaders were very much the same as those found in private sector.

    2016-10-01

    This paper aimed to examine pedestrians' self-reported violating crossing behavior intentions by applying the theory of planned behavior (TPB). We studied the behavior intentions regarding instrumental attitude, subjective norm, perceived behavioral control, the three basic components of TPB, and extended the theory by adding new factors including descriptive norm, perceived risk and conformity tendency to evaluate their respective impacts on pedestrians' behavior intentions. A questionnaire presented with a scenario that pedestrians crossed the road violating the pedestrian lights at an intersection was designed, and the survey was conducted in Dalian, China. Based on the 260 complete and valid responses, reliability and validity of the data for each question was evaluated. The data were then analyzed by using the structural equation modeling (SEM). The results showed that people had a negative attitude toward the behavior of violating road-crossing rules; they perceived social influences from their family and friends; and they believed that this kind of risky behavior would potentially harm them in a traffic accident. The results also showed that instrumental attitude and subjective norm were significant in the basic TPB model. After adding descriptive norm, subjective norm was no more significant. Other models showed that conformity tendency was a strong predictor, indicating that the presence of other pedestrians would influence behavioral intention. The findings could help to design more effective interventions and safety campaigns, such as changing people's attitude toward this violation behavior, correcting the social norms, increasing their safety awareness, etc. in order to reduce pedestrians' road crossing violations.

    Risky sexual behavior, particularly among adolescents, continues to be a major source of concern. In order to develop effective education and prevention programs, there is a need for research that identifies the antecedents of such behavior. This study investigated the mediators that link parenting experiences during early adolescence to subsequent risky sexual behaviors among a diverse sample of African American youth (N = 629, 55 % female). While there is ample evidence that parenting practices (e.g., supportive parenting, harsh parenting, parental management) are antecedent to risky sexual behavior, few studies have examined whether one approach to parenting is more strongly related to risky sex than others. Using a developmental approach, the current study focused on factors associated with six theories of risky sexual behavior. While past research has provided support for all of the theories, few studies have assessed the relative contribution of each while controlling for the processes proposed by the others. The current study addresses these gaps in the literature and reports results separately by gender. Longitudinal analyses using structural equation modeling revealed that the mediating mechanisms associated with social learning and attachment theories were significantly related to the risky sexual behavior of males and females. Additionally, there was support for social control and self-control theories only for females and for life history theory only for males. We did not find support for problem behavior theory, a perspective that dominates the risky sex literature, after controlling for the factors associated with the other theories. Finally, supportive parenting emerged as the parenting behavior most influential with regard to adolescents' risky sexual behavior. These results provide insight regarding efficacious approaches to education and preventative programs designed to reduce risky sexual behaviors among adolescents. PMID:26718543

    2016-09-01

    Meta-analyses reveal that behavioral differences between liars and truth tellers are small. To facilitate lie detection, researchers are currently developing interviewing approaches to increase these differences. Some of these approaches assume that lying is cognitively more difficult than truth telling; however, they are not based on specific cognitive theories of lie production, which are rare. Here we examined one existing theory, Walczyk et al.'s (2014) Activation-Decision-Construction-Action Theory (ADCAT). We tested the Decision component. According to ADCAT, people decide whether to lie or tell the truth as if they were using a specific mathematical formula to calculate the motivation to lie from (a) the probability of a number of outcomes derived from lying vs. telling the truth, and (b) the costs/benefits associated with each outcome. In this study, participants read several hypothetical scenarios and indicated whether they would lie or tell the truth in each scenario (Questionnaire 1). Next, they answered several questions about the consequences of lying vs. telling the truth in each scenario, and rated the probability and valence of each consequence (Questionnaire 2). Significant associations were found between the participants' dichotomous decision to lie/tell the truth in Questionnaire 1 and their motivation to lie scores calculated from the Questionnaire 2 data. However, interestingly, whereas the expected consequences of truth telling were associated with the decision to lie vs. tell the truth, the expected consequences of lying were not. Suggestions are made to refine ADCAT, which can be a useful theoretical framework to guide deception research. PMID:27219533

  14. Extending unified-theory-of-reinforcement neural networks to steady-state operant behavior.

    Science.gov (United States)

    Calvin, Olivia L; McDowell, J J

    2016-06-01

    The unified theory of reinforcement has been used to develop models of behavior over the last 20 years (Donahoe et al., 1993). Previous research has focused on the theory's concordance with the respondent behavior of humans and animals. In this experiment, neural networks were developed from the theory to extend the unified theory of reinforcement to operant behavior on single-alternative variable-interval schedules. This area of operant research was selected because previously developed neural networks could be applied to it without significant alteration. Previous research with humans and animals indicates that the pattern of their steady-state behavior is hyperbolic when plotted against the obtained rate of reinforcement (Herrnstein, 1970). A genetic algorithm was used in the first part of the experiment to determine parameter values for the neural networks, because values that were used in previous research did not result in a hyperbolic pattern of behavior. After finding these parameters, hyperbolic and other similar functions were fitted to the behavior produced by the neural networks. The form of the neural network's behavior was best described by an exponentiated hyperbola (McDowell, 1986; McLean and White, 1983; Wearden, 1981), which was derived from the generalized matching law (Baum, 1974). In post-hoc analyses the addition of a baseline rate of behavior significantly improved the fit of the exponentiated hyperbola and removed systematic residuals. The form of this function was consistent with human and animal behavior, but the estimated parameter values were not. PMID:27018201

    2016-08-01

    The theory of planned behavior (TPB) has received its fair share of criticism lately, including calls for it to retire. We contribute to improving the theory by testing extensions such as the model of goal-directed behavior (MGDB, which adds desire and anticipated positive and negative emotions) applied to physical activity (PA) intention. We also test the inclusion of a descriptive norms construct as an addition to the subjective norms construct, also applied to PA, resulting in two additional models: TPB including descriptive norms (TPB + DN) and MGDB including descriptive norms (MGDB + DN). The study is based on an online survey of 400 young adult Internet users, previously enrolled in a subject pool. Confirmatory factor analysis (CFA) showed that TPB and TPB + DN were not fit for purpose, while MGDB and MGDB + DN were. Structural equation modelling (SEM) conducted on MGDB and MGDB + DN showed that the inclusion of descriptive norms took over the significance of injunctive norms, and increased the model's account of total variance in intention to be physically active.

    1989-09-25

    A path integral construction of superconformal field theories is presented based on gauged supersymmetric Wess-Zumino-Witten actions. The conformal charge of the model is identical to that of a GKO construction. Ghost modes appear in the formalism as a result of gauge fixing. As a consequence, the holomorphic stress-tensor T(z) and superconformal generator G(z) obtained in the construction have ghost contributions. Weak operator first-class constraints restrict the theory to physical states which satisfy the constraints. The superconformal algebra closes when evaluated between ghost-free physical states.

    De Leo, Joseph Anthony; Wulfert, Edelgard

    2013-03-01

    Given the widespread use of the Internet, researchers have begun to examine the personal and social consequences associated with excessive online involvement. The present study examined college students' problematic Internet use (PIU) behaviors within the framework of Jessor and Jessor's (1977) problem-behavior theory. Its specific aim was to investigate the links between PIU with both internalizing (depression, social anxiety) and externalizing (substance use and other risky behaviors) problems. Relevant variables from the perceived environmental system, the personality system, and the behavioral system were entered in a canonical correlation analysis. The analysis yielded two distinct functions: the first function, titled traditional problem-behavior syndrome, characterized students who are impulsive, hold socially deviant attitudes and show a propensity to use tobacco and illicit drugs. The second function, titled problematic Internet-behavior syndrome, characterized students who are socially anxious, depressed, report conflictive family relations, and show a propensity toward PIU. Thus, PIU did not share the characteristics typically associated with the traditional problem-behavior syndrome consistent with problem-behavior theory, but showed correlates more consistent with internalizing rather than externalizing problems.

We find two different solutions of the saddle point equations in the large N limit. With these solutions we compute the free energy and find that there is a first order phase transition. Our results may predict a phase transition in the dual gravity theory.

  4. Neutronics equations: Positiveness; compactness; spectral theory; time asymptotic behavior

    International Nuclear Information System (INIS)

    Neutronics equations are studied: the continuous model (with and without delayed neutrons) and the multigroup model. Asymptotic descriptions of these equations (t→+∞) are obtained, either by the Dunford method or by using semigroup perturbation techniques, after deriving the spectral theory for the equations. Compactness problems are reviewed, and a general theory of compact injection in neutronic functional space is derived. The effects of positiveness in neutronics are analyzed: the irreducibility of the transport semigroup, and the properties of the main eigenvalue (existence, nonexistence, frame, strict dominance, strict monotony in relation to all the parameters). A class of transport operators whose real spectrum can be completely described is shown

    Full Text Available Appropriate trust and leadership have been frequently cited as key answer to the problems of cooperation and coordination in contractor’s teamwork. The objectives of this paper are to measure trust level of construction projects team, to investigate trustworthy leadership behavior of project managers, and to model the influence of project managers’ trustworthy leadership behavior upon team trust level. Sixty-one respondents from nine on-going construction projects participated in the questionnaire survey. The analyses show that in general the levels of trust and project managers’ trustworthy leadership behavior are medium (scores of 82.71 and 102.09 respectively. Meanwhile the positive influence of project managers’ trustworthy leadership behavior upon team trust level, modeled through multiple regression analysis with one dependent variable (i.e. trust and three independent variables (i.e. leadership-results, leadership-integrity, and leadership-concern, is found to be significant. The model is evaluated and validated; the results reveal that the prediction of the model is satisfactory.

    In a riot situation some individuals actively participate in antisocial behavior, but others do not, and still others act to discourage hostile activity. Four concepts from general psychology including (1) insufficiency of internal control or lack of internalized restraints acquired through learning, (2) effects of frustration, (3) emotional excitement, and (4) precipitating incidents (one or more) are proposed as contributors to the behavioral involvement of participants. Some hypotheses and the role of such variables as emotional contagion, imitation, opportunism, and anonymity are discussed. PMID:8969079

    Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle school. The subjects completed a pre-tested questionnaire. The average monthly frequency of fast food consumption was 4.05 (4.25 for boys, 3.83 for girls). As expected, fast food consumption was considered to be a special event rather than part of an everyday diet, closely associated with meeting friends or celebrating, most likely with friends, special days. The Theory of Planned Behavior effectively explained fast food consumption behaviors with relatively high R2 around 0.6. Multiple regression analyses showed that fast food consumption behavior was significantly related to behavioral intention (b = 0.61, P < 0.001) and perceived behavioral control (b = 0.19, P < 0.001). Further analysis showed that behavioral intention was significantly related to subjective norm (b = 0.15, P < 0.01) and perceived behavioral control (b = 0.56, P < 0.001). Attitude toward fast food consumption was not significantly associated with behavioral intention. Therefore, effective nutrition education programs on fast food consumption should include components to change the subjective norms of fast food consumption, especially among peers, and perceived behavioral control. Further studies should examine effective ways of changing subjective norms and possible alternatives to fast food consumption for students to alter perceived behavioral control. PMID:21556232

    Forstner, C.

    2005-07-01

    This paper touches on some general questions of theory construction in physics, by presenting a biographical case study of David Bohm through the perspective of Fleckian thought-collectives and their thought-style. In the 1920s a small elite of physicists established the Copenhagen Interpretation of quantum mechanics as a new thought-style in the thought-collective of the physicists. In the following decade the Copenhagen Interpretation was transferred from Europe to the USA, from one thought-collective into another, and was integrated into a specific American thought-style. David Bohm was initiated in this mode of thought during his undergraduate studies at the Pennsylvania State College and his graduate studies at Caltech and the University of California at Berkeley.

    Science.gov (United States)

    Harju, Antti J.

    2014-08-01

    This is a study of twisted K-theory on a product space T×M. The twisting comes from a decomposable cup product class which applies the 1-cohomology of T and the 2-cohomology of M. In the case of a topological product, we give a concrete realization for the gerbe associated to a cup product characteristic class and use this to realize twisted K1-theory elements in terms of supercharge sections in a Fredholm bundle. The nontriviality of this construction is proved. Equivariant twisted K-theory and gerbes are studied in the product case as well. This part applies Lie groupoid theory. Superconnection formalism is used to provide a construction for characteristic polynomials which are used to extract information from the twisted K-theory classes.

    We examine the Hagedorn behavior of little string theory using its conjectured duality with near-horizon NS5-branes. In particular, by studying the string-corrected NS5-brane supergravity solution, it is shown that tree-level corrections to the temperature vanish, while the leading one-loop string...... correction generates the correct temperature dependence of the entropy near the Hagedorn temperature. Finally, the Hagedorn behavior of ODp-brane theories, which are deformed versions of little string theory, is considered via their supergravity duals....

  6. Following Human Footsteps: Proposal of a Decision Theory Based on Human Behavior

    Science.gov (United States)

    Mahmud, Faisal

    2011-01-01

    Human behavior is a complex nature which depends on circumstances and decisions varying from time to time as well as place to place. The way a decision is made either directly or indirectly related to the availability of the options. These options though appear at random nature, have a solid directional way for decision making. In this paper, a decision theory is proposed which is based on human behavior. The theory is structured with model sets that will show the all possible combinations for making a decision, A virtual and simulated environment is considered to show the results of the proposed decision theory

    Science.gov (United States)

    Elliott, Mark A; Armitage, Christopher J; Baughan, Christopher J

    2003-10-01

    The theory of planned behavior (TPB; I. Ajzen, 1985) was applied to drivers' compliance with speed limits. Questionnaire data were collected for 598 drivers at 2 time points separated by 3 months. TPB variables, demographic information, and self-reported prior behavior were measured at Time 1, and self-reported subsequent behavior was measured at Time 2. In line with the TPB, attitude, subjective norm, and perceived control were positively associated with behavioral intention, and intention and perceived control were positively associated with subsequent behavior. TPB variables mediated the effects of age and gender on behavior. Prior behavior was found to moderate the perceived control-intention and perceived control-subsequent behavior relationships. Practical implications of the findings for road safety and possible avenues for further research are discussed. PMID:14516256

  14. Universal behavior after a quantum quench in interacting field theories

    Science.gov (United States)

    Mitra, Aditi

    The dynamics of an isolated quantum system represented by a field theory with O(N) symmetry, and in d>2 spatial dimensions, is investigated after a quantum quench from a disordered initial state to the critical point. A perturbative renormalization-group approach involving an expansion around d=4 is employed to study the time-evolution, and is supplemented by an exact solution of the Hartree-Fock equations in the large-N limit. The results show that the dynamics is characterized by a prethermal regime controlled by elastic dephasing where excitations propagate ballistically, and a light cone emerges in correlation functions in real space. The memory of the initial state, together with the absence of time-scales at the critical point, gives rise to universal power-law aging which is characterized by a new non-equilibrium short-time exponent. The dynamics of the entanglement following a quench is also explored, and reveals that while the time evolution of the entanglement entropy itself is not much different between a free bosonic theory and an interacting bosonic theory, the low-energy entanglement spectrum on the other hand shows clear signature of the non-equilibrium short-time exponent related to aging. This work was done in collaboration with Y. Lemonik (NYU), M. Tavora (NYU), A. Chiocchetta (SISSA), A. Maraga (SISSA), and A. Gambassi (SISSA). Supported by NSF-DMR 1303177.

  15. Environmental indifference? A critique of environmentally deterministic theories of peatland archaeological site construction in Ireland

    Science.gov (United States)

    Plunkett, G.; McDermott, C.; Swindles, G. T.; Brown, D. M.

    2013-02-01

    Climate change, whether gradual or sudden, has frequently been invoked as a causal factor to explain many aspects of cultural change during the prehistoric and early historic periods. Critiquing such theories has often proven difficult, not least because of the imprecise dating of many aspects of the palaeoclimate or archaeological records and the difficulties of merging the two strands of research. Here we consider one example of the archaeological record - peatland site construction in Ireland - which has previously been interpreted in terms of social response to climate change and examine whether close scrutiny of the archaeological and palaeoenvironmental records upholds the climatically deterministic hypotheses. We evaluate evidence for phasing in the temporal distribution of trackways and related sites in Irish peatlands, of which more than 3500 examples have been recorded, through the examination of ˜350 dendrochronological and 14C dates from these structures. The role of climate change in influencing when such sites were constructed is assessed by comparing visually and statistically the frequency of sites over the last 4500 years with well-dated, multiproxy climate reconstructions from Irish peatlands. We demonstrate that national patterns of “peatland activity” exist that indicate that the construction of sites in bogs was neither a constant nor random phenomenon. Phases of activity (i.e. periods in which the number of structures increased), as well as the ‘lulls’ that separate them, show no consistent correlation with periods of wetter or drier conditions on the bogs, suggesting that the impetus for the start or cessation of such activity was not climatically-determined. We propose that trigger(s) for peatland site construction in Ireland must instead also be sought within the wider, contemporary social background. Perhaps not surprisingly, a comparison with archaeological and palynological evidence shows that peatland activity tends to occur at

  16. Optimization of “T”-Shaped Fins Geometry Using Constructal Theory and “FEA” Concepts

    2014-12-01

    Full Text Available This paper reports the geometric (constructal optimization of T-shaped fin assemblies, where the objective is to maximize the global thermal conductance of the assembly, subject to total volume and fin-material constraints. Assemblies of plate fins are considered. It is shown that every geometric feature of the assembly is delivered by the optimization principle and the constraints. These optimal features are reported in dimensionless terms for this entire class of fin assemblies. Based on the constructal theory by Dr. A Bejan, T-shaped fins are developed for better heat conductance as compared to conventional fins. Now the geometry of this T type of fin contains many geometry parameters which affect the overall conductance of the fin. With the same material constraint and volume constraints optimal geometry ratios has been calculated so as to design the fin for its best performance. With focus to the practical situations and heat flow patterns, it is quite complex to calculate the temperatures on a T-shaped fin. It requires the help of FEA concepts and CAE software to optimize the geometry.

  17. Credibility assessment: preliminary process theory, the polygraph process, and construct validity.

    Science.gov (United States)

    Palmatier, John J; Rovner, Louis

    2015-01-01

    The term "polygraph test," particularly in a forensic context, is used generally to describe diagnostic procedures using a polygraph instrument to assess credibility. Polygraph testing has been subject to greater scrutiny, debate, and empirical study than many other forensic techniques. It has been repeatedly demonstrated that, when used properly, the polygraph testing process functions with a high degree of predictive (criterion) validity. However, advocates have failed to address, in a substantive manner, the primary objection often cited by opponents that the polygraph procedure most used in applied day-to-day contexts, that is, Comparison Question Testing (CQT), is atheoretical and lacking construct validity. A review of the available research literature, including that from the neurosciences, psychophysiology, and other relevant disciplines, coupled with an intimate understanding of two commonly used polygraph procedures, the context in which they are used, and the scientific method, strongly suggests that such claims are no longer true, nor warranted. Here, we discuss the interplay of the two most advocated polygraph procedures, the CQT and CIT (Concealed Information Testing), with Preliminary Process Theory (PPT), contemporary writings on memory and other contributions from the research literature relevant to the instrumental assessment of credibility. We conclude that the available scientific evidence not only establishes a plausible theoretical construct that strengthens the practical application of the polygraph process in forensic and other settings, but also concurrently provides directions for future research by scientists interested in the applied assessment of credibility.

  18. Massive-scale gene co-expression network construction and robustness testing using random matrix theory.

    Directory of Open Access Journals (Sweden)

    Scott M Gibson

    Full Text Available The study of gene relationships and their effect on biological function and phenotype is a focal point in systems biology. Gene co-expression networks built using microarray expression profiles are one technique for discovering and interpreting gene relationships. A knowledge-independent thresholding technique, such as Random Matrix Theory (RMT, is useful for identifying meaningful relationships. Highly connected genes in the thresholded network are then grouped into modules that provide insight into their collective functionality. While it has been shown that co-expression networks are biologically relevant, it has not been determined to what extent any given network is functionally robust given perturbations in the input sample set. For such a test, hundreds of networks are needed and hence a tool to rapidly construct these networks. To examine functional robustness of networks with varying input, we enhanced an existing RMT implementation for improved scalability and tested functional robustness of human (Homo sapiens, rice (Oryza sativa and budding yeast (Saccharomyces cerevisiae. We demonstrate dramatic decrease in network construction time and computational requirements and show that despite some variation in global properties between networks, functional similarity remains high. Moreover, the biological function captured by co-expression networks thresholded by RMT is highly robust.

    2008-11-01

    Full Text Available Over the last several decades, rising unemployment and low salaries have caused many to blame “the others” for the crisis, fostering a negative attitude in the population toward outsiders. In this situation, the immigrant is seen as a threat, an illegitimate appropriator of the few social resources still available. This study approaches the construction of “the other” as inferior and stigmatic, using the point of view from social theories of learning. The methodology was a qualitative study of a biographical account without a complete sequence, using the sample randomly. The ancestors of our subject come from the pre-Incaic culture, the Huancas (from which his fictitious name, Wanca, was derived. He is a student from Huancayo, Peru: olive-colored skin, short height, protruding cheeks and dark hair. Her account reveals the construction of cultural and racial stereotypes in the university space, showing as well how these stereotypes are attributable to certain situations. In addition, studying the stigmatization of the immigrant facilitates an analysis of the modes of exclusion of other social groups due to their poverty, lack of education, or age.

  20. CONSTRUCTING MINIMAL SPANNING TREE BASED ON ROUGH SET THEORY FOR GENE SELECTION

    Directory of Open Access Journals (Sweden)

    Soumen Kumar Pati

    2013-01-01

    Full Text Available Microarray gene dataset often contains high dimensionalities which cause difficulty in clustering and classification. Datasets containing huge number of genes lead to increased complexity and therefore, degradation of dataset handling performance. Often, all the measured features of these high-dimensional datasets are not relevant for understanding the underlying phenomena of interest. Dimensionality reduction by reduct generation is hence performed as an important step before clustering and classification. The reduced attribute set has the same characteristics as the entire set of attributes in the information system. In this paper, a new attribute reduction technique, based on directed minimal spanning tree and rough set theory is done, for unsupervised learning. The method, firstly, computes a similarity factor between each pair of attributes using indiscernibility relation, a concept of rough set theory. Based on the similarity factors, an attribute similarity set is formed from which a directed weighted graph with vertices as attributes and edge weights as the inverse of the similarity factor is constructed. Then, all possible minimal spanning trees of the graph are generated. From each tree, iteratively, the most important vertex is included in the reduct set and all its out-going edges are removed. The process stops when the edge set is empty, thus producing multiple reducts. The proposed method and some well-known attribute reduction techniques have been applied on several microarray gene datasets for gene selection. The results obtained show the effectiveness of the method.

    Maternal reflective functioning (RF) has been associated with children's behavioral development. This study examined maternal prenatal and postnatal RF, as measured by the Pregnancy Interview and Parent Development Interview, as multidimensional constructs. It was also examined whether the RF-dimensions were associated with children's temperament and externalizing behavior, as assessed by several questionnaires. The sample consisted of 123 first-time mothers (M age=22.85years, SD=2.21) and their children (M age=19.97months, SD=0.85, 56% male). Two related but distinct dimensions were found for prenatal RF, termed self-focused and child-focused mentalization. Three dimensions were observed for postnatal RF, termed self-focused, child-focused, and relation-focused mentalization. Results showed that prenatal RF negatively related to reported child physical aggression. Postnatal self-focused RF was positively linked to externalizing behavior and negative emotionality in offspring, while relation-focused RF scores were negatively associated with child physical aggression. Findings show that it is important to also look at the specific RF-dimensions when examining the effects of maternal RF on children's behavioral development, as differential associations with behavioral outcomes exist. Discussion further focuses on the importance of these findings in prevention and clinical practice, and suggestions are being made to further improve the measurement of maternal RF-dimensions.

  3. Behavioral Competence as a Positive Youth Development Construct: A Conceptual Review

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Behavioral competence is delineated in terms of four parameters: (a Moral and Social Knowledge, (b Social Skills, (c Positive Characters and Positive Attributes, and (d Behavioral Decision Process and Action Taking. Since Ma’s other papers in this special issue have already discussed the moral and social knowledge as well as the social skills associated in detail, this paper focuses on the last two parameters. It is hypothesized that the following twelve positive characters are highly related to behavioral competence: humanity, intelligence, courage, conscience, autonomy, respect, responsibility, naturalness, loyalty, humility, assertiveness, and perseverance. Large-scale empirical future studies should be conducted to substantiate the predictive validity of the complete set of these positive characters. The whole judgment and behavioral decision process is constructed based on the information processing approach. The direction of future studies should focus more on the complex input, central control, and output subprocesses and the interactions among these sub-processes. The understanding of the formation of behavior is crucial to whole-person education and positive youth development.

    This paper reviews the characteristics of cognitive theories and their links to behavioral science and advanced intelligent systems. Cognitive theories model human cognition, perception, and communication. They suggest the human functions the system should have, serve as a philosophical basis for system development, and provide abstract design guidelines. The underlying assumption behind this paper is that if the cognitive theories are to have any value at all, they must be translated into usable systems. A process for testing a cognitive theory in terms of conceptual criteria, behavioral predictions and tests, and software development and tests, is suggested. Criteria for measuring the problem solving success of the advanced system are described. A theory of the system as an intelligent problem solver is presented. (author)

  7. THEORY OF REASONED ACTION FOR CONTINUOUS IMPROVEMENT CAPABILITIES: A BEHAVIORAL APPROACH

    Full Text Available The importance of interaction between Operations Management (OM and Human Behavior has been recently re-addressed. This paper introduced the Reasoned Action Theory suggested by Froehle and Roth (2004 to analyze Operational Capabilities exploring the suitability of this model in the context of OM. It also seeks to discuss the behavioral aspects of operational capabilities from the perspective of organizational routines. This theory was operationalized using Fishbein and Ajzen (F/A behavioral model and a multi-case strategy was employed to analyze the Continuous Improvement (CI capability. The results posit that the model explains partially the CI behavior in an operational context and some contingency variables might influence the general relationsamong the variables involved in the F/A model. Thus intention might not be the determinant variable of behavior in this context.

    Full Text Available Introduction & Objective: Sedentary women are at risk for problems such as obesity, diabetes, depression and cardiovascular disease. Meanwhile, due to long working hours and excessive travel time from home to work and vice versa the employees have minimal physical activity .The purpose of this study was to investigate the effective psychometric factors on physical activity of female employees, according to the Trans-theoretical Model and theory of planned behavior. Materials & Methods: In this cross-sectional study, 95 female staff of Tehran University was selected through a call. In order to collect data, a questionnaire with acceptable, reliability and validity, including demographic data, and constructs of planned behavior theory as well as Trans-theoretical Model was used. The data was analyzed using SPSS version 21 statisti-cal tests; correlation and stepwise regression were also performed. Results: In this study, 72% of the population was in the inactive stages (pre-contemplation, contemplation and preparation and only 28% of patients had regular physical activity. There was a significant positive correlation between the behavioral intention and attitude scores (P = 0.02, perceived behavioral control (P = 0.000, self-efficacy (P = 0.000 and stage of change (P = 0.000, but subjective norms score (P = 0.605 was irrelevant. Conclusion: The results of this study showed that self-efficacy and perceived behavioral con-trol can affect female employees’ intention and physical activity behaviors. So, the authori-ties should seriously consider these factors in educational planning for this stratum of society, remove barriers for the participation of more employees in sporting activities, and offer fa-cilitators at the community level.

  9. Construction behavior of the first underground opening of the superconducting super collider project

    International Nuclear Information System (INIS)

    Most underground structures of the Superconducting Super Collider (SSC) will be within the competent Austin Chalk (AC), an ideal tunneling medium; however, some structures will be within the very low strength Eagle Ford Shale (EFS). A 3 m diameter Exploratory Shaft, 82 m deep with a test adit at the AC/EFS contact was constructed as the first underground opening on the SSC to provide information on design parameters and construction behavior. The Exploratory Shaft was instrumented with piezometers, MPBXs, convergence anchors, inclinometer and heave gage casings, and an instrumented steel ring liner section. The shaft was deep enough to induce over-stress in the EFS. The geomechanical properties of the EFS and overlying AC, the instrumentation, and the insights gained for the SSC project are presented in this paper

  10. Decision Making Method Based on Importance-Dangerousness Analysis for the Potential Risk Behavior of Construction Laborers

    2015-01-01

    Full Text Available Unsafe behavior contributes to 90% of the causes of construction accidents. To prevent construction accidents, studies on existing unsafe behaviors have been regularly conducted. However, existing studies generally tend to average the survey results and conduct analyses thereon, and such a method cannot consider the potential risk as regards people’s anxiety about a certain unsafe behavior. Thus, this research suggests an Importance-Dangerousness Analysis (IDA technique so that potential risks due to unsafe behaviors of laborers working in the construction sector could be evaluated. In order to verify the applicability of the suggested technique, an actual survey was conducted, and the results of Importance-Performance Analysis (IPA and IDA were compared with each other. It was found that, unlike IPA, unsafe behaviors that could pose potential risks were confirmed by IDA. Further, unsafe behaviors in the construction sector that should be urgently addressed were also studied. Finally, the IDA suggested in this research could contribute to effective construction safety management on-site by supporting the decisions of the safety manager based on the unsafe behavior analysis of construction laborers.

    The purpose of this research was to investigate variables relevant to smoking cessation early in the process of change through an application of the Theory of Planned Behavior [Ajzen, I. (1985). From intentions to actions: A theory of planned behavior. In J. Kuhl and J. Beckman (Eds). Action-control: From cognition to behavior (pp.11-39). Heidelberg: Springer.] to the temporal structure provided by the Transtheoretical Model. Study 1 was a preliminary elicitation study (n=68) conducted to ground the concepts used in the model testing in Study 2 [Ajzen, I., Fishbein, M. (1980). Understanding attitudes and predicting social behavior, Englewood Cliffs, NJ: Prentice-Hall.]. Study 2 tested the proposed model fit with data from a sample of 230 adult smokers. Structural equation modeling did not support the Theory of Planned Behavior as a model of motivation for progress through the stages of change and highlighted measurement issues with perceived behavioral control. A modified model using the Theory of Reasoned Action provided a good fit to the data, accounting for approximately 64% of the variance in intention to quit smoking and stage of change. This research addresses the need for a more complete theoretical rationale for progress through stages of change. PMID:16182458

    2002-01-01

    The present research details 2 empirical tests within the context of the theory of planned behavior (I. Ajzen & T. Madden, 1986) of the assumption that preparatory behaviors (e.g., discussing safer sex, obtaining condoms) play a mediational role in the relation between psychological variables (e.g., attitudes toward safer sex, social norms about safer sex) and condom use. The assumption of the mediational role of preparatory behaviors is examined in sexually experienced samples from 2 different populations: inner-city high school students (N = 226) and college students (N = 160). The results suggest that the mediational role of preparatory behaviors is a highly significant one. Results indicate no gender differences with regard to the main mediational hypotheses. The methodological, theoretical, and practical implications and importance of these findings are discussed. PMID:11846347

    Full Text Available This study investigates the factors affecting borrowing intention among young entrepreneur of Indonesia TDA community based on the Theory of Planned Behavior (TPB. About 100 questionnaires were accepted and analyzed using structural equation modeling (SEM in determining the relationships. The results show that borrowing intention amongst young entrepreneur of Indonesia TDA community is influenced by attitude, subjective norms, perceived behavior control, self identity, situational temptation, and past behavior. The young entrepreneur of Indonesia TDA community believe that they have complete control of their behavior in borrowing as they perceived to be equipped with the knowledge about the personal financing. In addition, because of their experience in students’ loans since undergraduates’ level, the result explains why situational temptation were found to be a significant predictor. The findings offer implications for researchers and government.

    Given that current television programming contains numerous gambling portrayals, it is imperative to understand whether and to what extent these gambling behaviors in media influence individuals' beliefs, attitudes, and intentions. This study explores an extended model of the theory of reasoned action (TRA) by including gambling media exposure as a distal, mediating and mediated factor in predicting undergraduate students' intentions to gamble in a casino. Findings show that the extended model of TRA clearly indicates that the constructs of gambling media exposure, prior gambling experience, and level of gambling addiction contribute to the prediction of undergraduate students' casino gambling intentions. Theoretical implications of gambling media effects and practical implications for public policy are discussed, and future research directions are outlined. PMID:22477238

    Our objective was to evaluate the efficacy of a cultural adaptation of a social cognitive theory-based HIV behavioral prevention program among young rural-to-urban migrants in China. The intervention design and assessment were guided by the Protection Motivation Theory (PMT). The intervention was evaluated through a randomized controlled trial with 6-month and 12-month follow-ups. The primary behavioral outcome was the use of condoms. Other outcome measures include HIV knowledge, condom use knowledge, HIV-related perceptions (PMT constructs), and intention to use condom. The mixed-effects regression models for condom use with regular partners indicated that overall frequency of condom use, condom use in last three sexual acts and proper condom use increased over time for the participants but the increases were significantly greater among the intervention group than the control group at 6-month and 12-month follow-ups. The mixed-effects models for HIV-related perceptions indicated that extrinsic rewards, intrinsic rewards, and response costs decreased while vulnerability, severity, response efficacy, and self-efficacy increased over time for the intervention group. The increases in HIV knowledge, condom use knowledge, and intention to use condom were also significantly greater among the intervention group than the control group. The data in the current study suggested efficacy of a social cognitive theory-based behavioral intervention in increasing condom use among young migrants in China. The intervention also increased protective perceptions and decreased risk perception posited by the theory (i.e., PMT). PMID:25068178

    Models based on psychological biases can explain momentum and reversal in stock returns, but risk overfitting of theory to data. We examine a central psychological bias, representativeness, which underlies many behavioral-finance theories. According to this bias, individuals form predictions about future outcomes based on how closely past outcomes fit certain categories. To produce out-of sample tests, we use accounting performance to identify these categories and test the idea that investors...

  5. Causality and superluminal behavior in classical field theories: Applications to k-essence theories and modified-Newtonian-dynamics-like theories of gravity

    International Nuclear Information System (INIS)

    Field theories with Lorentz (or diffeomorphism invariant) action can exhibit superluminal behavior through the breaking of local Lorentz invariance. Quantum induced superluminal velocities are well-known examples of this effect. The issue of the causal behavior of such propagation is somewhat controversial in the literature and we intend to clarify it. We provide a careful analysis of the meaning of causality in classical relativistic field theories and stress the role played by the Cauchy problem and the notion of chronology. We show that, in general, superluminal behavior threatens causality only if one assumes that a prior chronology in spacetime exists. In the case where superluminal propagation occurs, however, there are at least two nonconformally related metrics in spacetime and thus two available notions of chronology. These two chronologies are on equal footing, and it would thus be misleading to choose ab initio one of them to define causality. Rather, we provide a formulation of causality in which no prior chronology is assumed. We argue that this is the only way to deal with the issue of causality in the case where some degrees of freedom propagate faster than others. In that framework, then, it is shown that superluminal propagation is not necessarily noncausal, the final answer depending on the existence of an initial data formulation. This also depends on global properties of spacetime that we discuss in detail. As an illustration of these conceptual issues, we consider two field theories, namely, k-essence scalar fields and bimetric theories of gravity, and we derive the conditions imposed by causality. We discuss various applications such as the dark energy problem, modified-Newtonian-dynamics-like theories of gravity, and varying speed of light theories

  7. Constructing Minimal Spanning Tree Based on Rough Set Theory for Gene Selection

    2013-02-01

    Full Text Available Microarray gene dataset often contains high dimensionalities which cause difficulty in clustering andclassification. Datasets containing huge number of genes lead to increased complexity and therefore,degradation of dataset handling performance. Often, all the measured features of these high-dimensionaldatasets are not relevant for understanding the underlying phenomena of interest. Dimensionality reductionby reduct generation is hence performed as an important step before clustering and classification. Thereduced attribute set has the same characteristics as the entire set of attributes in the information system.In this paper, a new attribute reduction technique, based on directed minimal spanning tree and rough settheory is done, for unsupervised learning. The method, firstly, computes a similarity factor between eachpair of attributes using indiscernibility relation, a concept of rough set theory. Based on the similarityfactors, an attribute similarity set is formed from which a directed weighted graph with vertices asattributes and edge weights as the inverse of the similarity factor is constructed. Then, all possible minimalspanning trees of the graph are generated. From each tree, iteratively, the most important vertex isincluded in the reduct set and all its out-going edges are removed. The process stops when the edge set isempty, thus producing multiple reducts. The proposed method and some well-known attribute reductiontechniques have been applied on several microarray gene datasets for gene selection. The results obtainedshow the effectiveness of the method.

    2013-02-01

    Full Text Available Interdisciplinary cooperation and collaboration have proven to be desirable yet difficult goals to achieve in social science research. The nuanced differences among the domains, frameworks, assumptions, and methods of the various fields of study that comprise such research often hinder attempts to engage in interdisciplinary dialogue that is both meaningful and productive. We show that demography, economics, political science, and sociology are a few of the fields at the vanguard of the interdisciplinary frontier that emerged following the Second World War. In light of the challenges that these fields (along with the natural sciences face in initiating and sustaining interdisciplinary dialogue, we aim to accomplish several tasks. First, we seek to describe the theoretical and epistemological linkages among the cores of these four social-science disciplines. Second, we explore systems theory as a potential foundation for interdisciplinary unity. Third, we extrapolate the implications of the systems approach to encompass the study of human populations from multiple disciplinary perspectives. In this vein, we also seek to characterize key features of human populations, parse their functions in various disciplinary contexts, and prospectively identify challenges in data interpretation and analysis that will likely emerge in practice. The ultimate goals of this study are to delineate a set of methodological standards with which to guide interdisciplinary inquiry in the social and natural sciences, and consider how we might implement these standards in the construction of a world-historical data archive. 

  9. The incidence of Freudian self-analysis in the construction of the psychoanalytic theory of anxiety.

    Science.gov (United States)

    Obaid, Francisco Pizarro

    2014-02-01

    The value and function of self-analysis has been a contentious issue in several studies dedicated to the Freudian legacy. For some writers, Freud's experience of self-analysis is rightly considered to be the master key to an understanding of the origins of the fundamentals of psychoanalysis. For others, the exaggerated importance attributed to the process merely led to the construction of a foundational myth. Nevertheless, if it is recognized to be a process in which Freud, in collaboration with Fliess, analysed personal aspects, working hypotheses and psychopathological debates, a reconsideration of self-analysis may contribute new elements to our understanding of the paths that were taken in the elaboration of the theory and practice of pyschoanalysis. Starting from this premise, the present work will consider the systematic examination that Freud conducted of his own phobia in the course of his self-analysis to be a process of great relevance to the elaboration of the early psychoanlytic conceptualizations of anxiety, in that in the course of this process the possible role of sexuality, fantasy, memory and unconscious determinism in the etiology of anxiety became part of the discussion.

  11. Toward a theory of distinct types of "impulsive" behaviors: A meta-analysis of self-report and behavioral measures.

    Science.gov (United States)

    Sharma, Leigh; Markon, Kristian E; Clark, Lee Anna

    2014-03-01

    Impulsivity is considered a personality trait affecting behavior in many life domains, from recreational activities to important decision making. When extreme, it is associated with mental health problems, such as substance use disorders, as well as with interpersonal and social difficulties, including juvenile delinquency and criminality. Yet, trait impulsivity may not be a unitary construct. We review commonly used self-report measures of personality trait impulsivity and related constructs (e.g., sensation seeking), plus the opposite pole, control or constraint. A meta-analytic principal-components factor analysis demonstrated that these scales comprise 3 distinct factors, each of which aligns with a broad, higher order personality factor-Neuroticism/Negative Emotionality, Disinhibition versus Constraint/Conscientiousness, and Extraversion/Positive Emotionality/Sensation Seeking. Moreover, Disinhibition versus Constraint/Conscientiousness comprise 2 correlated but distinct subfactors: Disinhibition versus Constraint and Conscientiousness/Will versus Resourcelessness. We also review laboratory tasks that purport to measure a construct similar to trait impulsivity. A meta-analytic principal-components factor analysis demonstrated that these tasks constitute 4 factors (Inattention, Inhibition, Impulsive Decision-Making, and Shifting). Although relations between these 2 measurement models are consistently low to very low, relations between both trait scales and laboratory behavioral tasks and daily-life impulsive behaviors are moderate. That is, both independently predict problematic daily-life impulsive behaviors, such as substance use, gambling, and delinquency; their joint use has incremental predictive power over the use of either type of measure alone and furthers our understanding of these important, problematic behaviors. Future use of confirmatory methods should help to ascertain with greater precision the number of and relations between impulsivity

The article seeks to explain internet and mobile enhanced citizen’s participation in democracy (e-democracy base on their inherent (attitude and environmental (subjective norms and perceived behavioral control enablers and barriers to participate in e-democracy, and how the internet and wireless technologies can help to address democratic issues in resource poor settings such as the Sub Saharan Africa (SSA. The study takes the perspective of critical realism and thus provides an example of the application of this research paradigm in an empirical study. We investigated this phenomenon by providing a theoretical grounded model that explains e-democracy adoption adapted from the theory of Planned Behavior (TPB and tested from an empirical examination of constructs using data from randomly selected sub-Saharan African countries. The results render support for the proposed hypotheses, emphasizing the role of human behavior on citizens’ e-democracy adoption.

    2001-01-01

    We construct a Galilean invariant nongravitational closed string theory whose excitations satisfy a nonrelativistic dispersion relation. This theory can be obtained by taking a consistent low energy limit of any of the conventional string theories, including the heterotic string. We give a finite first order worldsheet Hamiltonian for this theory and show that this string theory has a sensible perturbative expansion, interesting high energy behavior of scattering amplitudes and a Hagedorn tra...

    Polymer mixtures such as blends or block copolymers are of great interest in energy applications and functional materials, and often, one or more of these species contain charges. The traditional fashion in which such materials are studied uses Self-Consistent Field Theory (SCFT) methods that incorporate electrostatics using Poisson-Boltzmann (PB) theory. We adapt a new and rigorous approach that does not rely on the mean-field assumptions inherent in the PB theory and instead uses Liquid State (LS) integral equation theory to articulate charge correlations that are completely neglected in PB. We use this theory to calculate phase diagrams for both blends and block copolyelectrolytes using SCFT-LS and demonstrate how their phase behavior is highly dependent on chain length, charge fraction, charge size, and the strength of Coulombic interactions. Beyond providing phase behavior of blends and block copolyelectrolytes, we can use this theory to investigate the interfacial properties such as surface tension and block copolyelectrolyte lamellar spacing. Lamellar spacing provides a way to directly compare the SCFT-LS theory to the results of experiments. SCFT-LS will provide conceptual and mathematical clarification of the role of charge correlations in these systems and aid in the design of materials based on charge polymers.

    Full Text Available In the processes of physical activity (PA maintenance specific predictors are effective, which differ from other stages of PA development. Recently, Physical Activity Maintenance Theory (PAMT was specifically developed for prediction of PA maintenance. The aim of the present study was to evaluate the predictability of the future behavior by the PAMT and compare it with the Theory of Planned Behavior (TPB and Social Cognitive Theory (SCT. Participation rate in a fitness center was observed for 101 college students (53 female aged between 19 and 32 years (M = 23.6; SD = 2.9 over 20 weeks using a magnetic card. In order to predict the pattern of participation TPB, SCT and PAMT were used. A latent class zero-inflated Poisson growth curve analysis identified two participation patterns: regular attenders and intermittent exercisers. SCT showed the highest predictive power followed by PAMT and TPB. Impeding aspects as life stress and barriers were the strongest predictors suggesting that overcoming barriers might be an important aspect for exercise maintenance. Self-efficacy, perceived behavioral control, and social support could also significantly differentiate between the participation patterns.

    Full Text Available Telehealth has become an increasingly applied solution to delivering health care to rural and underserved areas by remote health care professionals. This study integrated social capital theory, social cognitive theory, and the technology acceptance model (TAM to develop a comprehensive behavioral model for analyzing the relationships among social capital factors (social capital theory, technological factors (TAM, and system self-efficacy (social cognitive theory in telehealth. The proposed framework was validated with 365 respondents from Nantou County, located in Central Taiwan. Structural equation modeling (SEM was used to assess the causal relationships that were hypothesized in the proposed model. The finding indicates that elderly residents generally reported positive perceptions toward the telehealth system. Generally, the findings show that social capital factors (social trust, institutional trust, and social participation significantly positively affect the technological factors (perceived ease of use and perceived usefulness respectively, which influenced usage intention. This study also confirmed that system self-efficacy was the salient antecedent of perceived ease of use. In addition, regarding the samples, the proposed model fitted considerably well. The proposed integrative psychosocial-technological model may serve as a theoretical basis for future research and can also offer empirical foresight to practitioners and researchers in the health departments of governments, hospitals, and rural communities.

  9. Applying behavioral theories to invasive animal management: Towards an integrated framework.

    2015-09-15

    Invasive species wreak an estimated $1.4 trillion in damages globally, each year. To have any hope of reducing this damage, best-practice control strategies must incorporate behavior change interventions. Traditional interventions, based on the knowledge-transfer model, assume that if land managers are properly educated about risks and strategies, they will develop supportive attitudes and implement appropriate control strategies. However, the social sciences have produced a large number of behavioral models and frameworks that demonstrate that knowledge transfer, by itself, fails to change behavior. The challenge then lies in knowing which behavioral model to choose, and when, from a potentially overwhelming 'universe'. In this paper, we review nine behavior theories relevant to invasive species management. We then introduce the Behavior Change Wheel as a tool for integrating these theories into a single practical framework. This framework links drivers of and barriers to behavior change with intervention strategies and policies, in what we consider, from an applied perspective, to be an important advance. PMID:26151198

    2016-01-01

    We examined the utility of an expanded Theory of Planned Behavior (TPB) model in predicting cervical cancer screening intentions among Latinas. The model included acculturation and past cervical cancer screening behavior along with attitude, subjective norms, and perceived behavioral control. This cross-sectional study included a sample of 206 Latinas who responded to a self-administered survey. Structural equation modeling was employed to test the expanded TPB model. Acculturation (p= .025) and past screening behavior (p= .001) along with attitude (p= .019), subjective norms (p= .028), and perceived behavioral control (p= .014) predicted the intention to be screened for cervical cancer. Our findings suggest that the TPB is a useful model for understanding cervical cancer screening intentions among Latinas when both past behavior and culture are included. This highlights the importance of culture on behavior and indicates a need to develop culturally sensitive, theory-based interventions to encourage screening and reduce cervical cancer-related health disparities in Latinas.

    Science.gov (United States)

    Perry, Armon Rashard; Langley, Cheri

    2013-06-01

    Implicit in much of the fatherhood discourse is the assumption that if fathers want to take an active role in their children's lives, they could and would do so. While research has highlighted the factors associated with fathers' involvement, very few, if any, of these studies have been guided by a theory that accounts for both fathers' involvement intentions and their ability to follow through on those intentions. The theory of planned behavior and its emphasis on attitudes, the beliefs of significant others, and whether one has control over engaging in behavior is a conceptual fit to respond to questions related to the complex nature of paternal involvement. Using data from the Fragile Families and Child Well-being Study, the purpose of this study was to test the utility of the theory of planned behavior in predicting fathers' involvement intentions and reports of involvement. The results revealed that the theory of planned behavior can be useful in examining paternal involvement and should be used in future research to enhance the fatherhood literature. PMID:23763679

  9. A Heart for Interaction: Physiological Entrainment and Behavioral Coordination in a Collective, Creative Construction Task

    CERN Document Server

    Fusaroli, Riccardo; Roepstoff, Andreas; Tylén, Kristian

    2015-01-01

    Interpersonal physiological entrainment is increasingly argued to underlie rapport, empathy and even team performance. Inspired by the model of interpersonal synergy, we investigate the presence, temporal development, possible mechanisms and impact of interpersonal heart rate entrainment during individual and collective creative LEGO construction tasks. In Study 1 we show how HR entrainment is driven by a plurality of sources including task constraints and behavioral coordination. Generally, HR entrainment is more prevalent in individual trials (involving participants doing the same things) than in collective ones (involving participants taking turns and performing complementary actions). However, when contrasted against virtual pairs, collective trials display more stable HR entrainment supporting the idea that online social interaction plays a role. Furthermore, HR entrainment is found to grow across collective but not individual trials. In Study 2 we further show that in collective trials the dynamics of H...

    Creep tests under at a certain temperature and different stress levels were performed on two carbon constructional quality steels at a certain stress level and different temperatures,and their creep curves at high temperature were obtained based on analyzing the testing data.Taking 45 steel at a certain temperature and stress as the example,the integral creep constitutive equation and the differential stress-strain constitutive relationship were established based on the relevant rheological model,and the integral core function was also obtained.Simultaneously,the viscous coefficients denoting the viscous behavior in visco-plastic constitutive equation were determined by taking use of the creep testing data.Then the viscous coefficients of three carbon steels(20 steel,35 steel and 45 steel) were compared and analyzed.The results show that the viscosity is different due to different materials at the same temperature and stress.

  11. An application of the theory of planned behavior to the proximal and distal etiology of sexual offending.

    Science.gov (United States)

    Miller, Diane Lynn

    2010-07-01

    Emerging from social psychology, the theory of planned behavior offers a potentially useful theoretical framework for research into the etiology of sexual offending in adults and adolescents. The theory of planned behavior--a cognitive-affective theory about the role of attitudes, subjective norms, and perceived behavioral control on behaviors--may provide a means by which to link distal etiological factors into proximal ones involved in the offense process, providing greater specificity to the ''abused- abuser'' hypothesis. The theory of planned behavior also provides a theoretical framework with which to specify mechanisms involved in the proximal offense cycle. Important new directions for research resulting from this conceptual advance are presented, along with limitations of the theory in its application to the etiology of sexual offending. This theoretical framework directs practitioners to classify sexual offenders' cognitive distortions by whether they involve behavioral beliefs, normative beliefs, and/or control beliefs and to modify treatment activities accordingly.

    Matsumura, Koki; Kawamoto, Masaru

    This paper proposed a new technique which makes the strategy trees for the derivative (option) trading investment decision based on the behavioral finance theory and optimizes it using evolutionary computation, in order to achieve high profitability. The strategy tree uses a technical analysis based on a statistical, experienced technique for the investment decision. The trading model is represented by various technical indexes, and the strategy tree is optimized by the genetic programming(GP) which is one of the evolutionary computations. Moreover, this paper proposed a method using the prospect theory based on the behavioral finance theory to set psychological bias for profit and deficit and attempted to select the appropriate strike price of option for the higher investment efficiency. As a result, this technique produced a good result and found the effectiveness of this trading model by the optimized dealings strategy.

  14. Dryson equations, Ward identities, and the infrared behavior of Yang-Mills theories

    International Nuclear Information System (INIS)

    It was shown using the Schwinger-Dyson equations and the Slavnov-Taylor identities of Yang-Mills theory that no inconsistency arises if the gluon propagator behaves like (1/p2)2 for small p2. To see whether the theory actually contains such singular long range behavior, a nonperturbative closed set of equations was formulated by neglecting the transverse parts of GAMMA and GAMMA4 in the Schwinger-Dyson equations. This simplification preserves all the symmetries of the theory and allows the possibility for a singular low-momentum behavior of the gluon propagator. The justification for neglecting GAMMA/sup (T)/ and GAMMA4/sup (T)/ is not evident but it is expected that the present study of the resulting equations will elucidate this simplification, which leads to a closed set of equations

    2011-10-01

    Full Text Available BackgroundFindings of most studies indicate that the only way to control diabetes and prevent its debilitating effects is through the continuous performance of self-care behaviors. Physical activity is a non-pharmacological method of diabetes treatment and because of its positive effects on diabetic patients, it is being increasingly considered by researchers and practitioners. This study aimed at determining factors influencing physical activity among diabetic women in Iran, using the extended theory of reasoned action in Iran.MethodsA sample of 352 women with type 2 diabetes, referring to a Diabetes Clinic in Khoy, Iran, participated in the study. Appropriate instruments were designed to measure the desired variables (knowledge of diabetes, personal beliefs, subjective norms, perceived self-efficacy, behavioral intention and physical activity behavior. The reliability and validity of the instruments were examined and approved. Statistical analyses of the study were conducted by inferential statistical techniques (independent t-test, correlations and regressions using the SPSS package.ResultsThe findings of this investigation indicated that among the constructs of the model, self efficacy was the strongest predictor of intentions among women with type 2 diabetes and both directly and indirectly affected physical activity. In addition to self efficacy, diabetic patients' physical activity also was influenced by other variables of the model and sociodemographic factors.ConclusionOur findings suggest that the high ability of the theory of reasoned action extended by self-efficacy in forecasting and explaining physical activity can be a base for educational intervention. Educational interventions based on the proposed model are necessary for improving diabetics' physical activity behavior and controlling disease.

    Objective. This study was conducted to identify some factors (beliefs and norms) which are related to fast food consumption among high school students in Isfahan, Iran. We used the framework of the theory planned behavior (TPB) to predict this behavior. Subjects & Methods. Cross-sectional data were available from high school students (n = 521) who were recruited by cluster randomized sampling. All of the students completed a questionnaire assessing variables of standard TPB model including attitude, subjective norms, perceived behavior control (PBC), and the additional variables past behavior, actual behavior control (ABC). Results. The TPB variables explained 25.7% of the variance in intentions with positive attitude as the strongest (β = 0.31, P < 0.001) and subjective norms as the weakest (β = 0.29, P < 0.001) determinant. Concurrently, intentions accounted for 6% of the variance for fast food consumption. Past behavior and ABC accounted for an additional amount of 20.4% of the variance in fast food consumption. Conclusion. Overall, the present study suggests that the TPB model is useful in predicting related beliefs and norms to the fast food consumption among adolescents. Subjective norms in TPB model and past behavior in TPB model with additional variables (past behavior and actual behavior control) were the most powerful predictors of fast food consumption. Therefore, TPB model may be a useful framework for planning intervention programs to reduce fast food consumption by students. PMID:23936635

    Full Text Available Objective. This study was conducted to identify some factors (beliefs and norms which are related to fast food consumption among high school students in Isfahan, Iran. We used the framework of the theory planned behavior (TPB to predict this behavior. Subjects & Methods. Cross-sectional data were available from high school students who were recruited by cluster randomized sampling. All of the students completed a questionnaire assessing variables of standard TPB model including attitude, subjective norms, perceived behavior control (PBC, and the additional variables past behavior, actual behavior control (ABC. Results. The TPB variables explained 25.7% of the variance in intentions with positive attitude as the strongest (, and subjective norms as the weakest (, determinant. Concurrently, intentions accounted for 6% of the variance for fast food consumption. Past behavior and ABC accounted for an additional amount of 20.4% of the variance in fast food consumption. Conclusion. Overall, the present study suggests that the TPB model is useful in predicting related beliefs and norms to the fast food consumption among adolescents. Subjective norms in TPB model and past behavior in TPB model with additional variables (past behavior and actual behavior control were the most powerful predictors of fast food consumption. Therefore, TPB model may be a useful framework for planning intervention programs to reduce fast food consumption by students.

    Full Text Available Many cities have encountered problems with uncollected solid waste. Separate disposal of recyclable waste is viewed as the most effective procedure in waste management. However, this requires the cooperation of the people in the community. Community mapping is the most effective tool for understanding a community but it does not address possible ways to change people’s behavior. The Theory of Planned Behavior was the basis for this study of recycling behavior as it offers methods for changing people’s habits. However, the theory does not provide guidance on how to facilitate the use of recycling bins in the community. Many recycling projects have been unsuccessfully implemented due to the fact that most people do not want waste bins placed near their houses. Therefore, both of these effective tools were combined in this study, which propose an effective implementation method for community solid waste management.

    Full Text Available Background: Studies report inappropriate snack and junk food consumption patterns in children and young adults in Iran. The current survey was aimed to explore fast food consumption behaviors in high-school students based on the Theory of Planned Behavior. Materials and Methods: A cross-sectional study was done among 500 high-school students. Samples were selected based on cluster sampling method at first and simple random at second. Data were collected using a researcher-made questionnaire. To analyze, SPSS-16 and tests, including t-test, Chi-square, correlation coefficient and multiple regressions were used. Results: The monthly frequency of fast food consumption was 4.01. The TPB explained fast food use behaviors with R2 of 0.6, effectively. Results also represented that frequency of fast food consumption was meaningfully in line with behavioral intention (β = 0.60, P < 0.05 and subjective norms (β = 0.17, P < 0.05. Conclusion: It seems likely beneficial to consider important subjective norms (especially friends that may strongly effect on high-school student intention to use fast food. Also students perceived behavioral control must be increased.

    The construct of involvement has been found to influence brand loyalty, product information search processing, responses to advertising communications, diffusion of innovations, and ultimately, product choice decisions. Traditionally, involvement has been defined as being a characteristic of either a product or of an individual. In the present research, we make an assumption that an individual's 'food involvement' is a somewhat stable characteristic and we hypothesized that involvement with foods would vary between individuals, that individuals who are more highly involved with food would be better able to discriminate between a set of food samples than would less food involved individuals, and that this discrimination would operate both in affective and perceptive relative judgments. Using standard scale construction techniques, we developed a measure of the characteristic of food involvement, based on activities relating to food acquisition, preparation, cooking, eating and disposal. After several iterations, a final 12-item measure was found to have good test-retest reliability and internal consistency within two subscales. A behavioral validation study demonstrated that measures of food involvement were associated with discrimination and hedonic ratings for a range of foods in a laboratory setting. These findings suggest that food involvement, as measured by the Food Involvement Scale, may be an important mediator to consider when undertaking research with food and food habits. PMID:12798781

  4. Construction of scales to measure leadership behavior at nuclear power plants. 2

    International Nuclear Information System (INIS)

    We tried to construct the PM leadership behavior measuring scales at nuclear power plants. In our factor analysis of leadership types of shift supervisors, maintenance and repair subsection chiefs and sub contractors' field leaders, three factors respectively were found. In the leadership scales for shift supervisors, the first factor was named the factor of group maintenance, the second factor was named the factor of directive-order for goal achievement and the third factor was named the factor of specialty for goal achievement. For maintenance and repair subsection chiefs, the first factor was named the factor of directive-order for goal achievement, and second factor was named the factor of group maintenance and the third factor was named the factor of rigidity-pressure for goal achievement. For subcontractors' leaders, the first factor was named the factor of directive-specialty for goal achievement, the second factor named the factor of group maintenance and the third factor was named the factor of rigidity-pressure for achievement. We constructed PM leadership measuring scales for each advisory position and verified its validity by using workplace 'morale'-(satisfaction, etc.) as a subordinate variable. Also, in regard to the distribution of scales, we verified the validity of distance scales by examining it by Quantification III. (author)

    The nightly construction of a 'nest' or sleeping platform is a behavior that has been observed in every wild great ape population studied, yet in captivity, few analyses have been performed on sleep related behavior. Here, we report on such behavior in three female and two male captive orangutans (Pongo spp.), in a natural light setting, at the Indianapolis Zoo. Behavioral samples were generated, using infrared cameras for a total of 47 nights (136.25 h), in summer (n = 25) and winter (n = 22) periods. To characterize sleep behaviors, we used all-occurrence sampling to generate platform construction episodes (n = 217). Orangutans used a total of 2.4 (SD = 1.2) techniques and 7.5 (SD = 6.3) actions to construct a sleeping platform; they spent 10.1 min (SD - 9.9 min) making the platform and showed a 77% preference for ground (vs. elevated) sleep sites. Comparisons between summer and winter platform construction showed winter start times (17:12 h) to be significantly earlier and longer in duration than summer start times (17:56 h). Orangutans should be provisioned with seasonally appropriate, high quality materials suitable for construction of sleeping platforms to increase sleep quality and improve animal health and welfare.

  6. Remarks on the effects of the Gribov copies on the infrared behavior of higher dimensional Yang-Mills theory

    2016-01-01

    In this paper, we discuss non-perturbative infrared features of Yang-Mills theory in Euclidean space-time dimensions greater than four in the Landau gauge and within the Refined Gribov-Zwanziger framework, which enables us to take into account the existence of gauge copies by restricting the domain of integration in the path integral to the Gribov region. Evidences for a decoupling/massive solution for the gluon propagator in higher dimensions are provided. This behavior is strengthened the bigger the dimension is. Further, we show that, by a dimensional reduction of the Refined Gribov-Zwanziger action from five to four dimensions, a non-perturbative coupling between the inverse of the Faddeev-Popov operator and the scalar field corresponding to the fifth component of the gauge field naturally arises, being in agreement with the recently proposed mechanism \\cite{Capri:2014bsa} to generalize the Refined Gribov-Zwanziger construction to the matter sector.

    Full Text Available Recognition for positive behavior is an appropriate response of the social environment to elicit desirable external behavior among the youth. Such positive responses, rendered from various social systems, include tangible and intangible reinforcements. The following theories are used to explain the importance of recognizing positive behavior: operational conditioning, observational learning, self-determination, and humanistic perspective. In the current work, culturally and socially desirable behaviors are discussed in detail with reference to Chinese adolescents. Positive behavior recognition is especially important to adolescent development because it promotes identity formation as well as cultivates moral reasoning and social perspective thinking from various social systems. The significance of recognizing positive behavior is illustrated through the support, tutorage, invitation, and subsidy provided by Hong Kong’s social systems in recognition of adolescent volunteerism. The practical implications of positive behavior recognition on youth development programs are also discussed in this work.

  8. Models of glassy behavior that attempt to understand mode coupling theories

    Glass transitions are said to be long time scale and short length scale phenomena. This makes the problem extremely difficult to treat theoretically. In this respect the current mode coupling theory (MCT) for glassy behavior, which is the only existing first principle dynamical theory has conceptual problems despite its spectacular successes. Proper understanding for the reasons of success is still lacking. There is an urgent need for deeper understanding and proper extention of the theory below the so-called mode coupling temperature below which the theory generally fails. With this aim in mind we have been developing a mean field type toy model. We are also developing a dynamical generalization of van der Waals model with Kac-type long range interaction. The talk will try to explain these and related developments in a plain language.

    1993-10-01

    In the Netherlands, the theory of planned behavior (Ajzen, 1991), the health belief model (Janz and Becker, 1984), and the protection-motivation theory (Rogers, 1983) were compared for predicting condom use intentions because of AIDS. The 641 respondents were given two questionnaires: one for themselves and another one for a friend, partner, or acquaintance. 514 (80%) of them returned completed forms. 60% of these (307) persons were encouraged to answer and return another questionnaire, thus the final sample consisted of 821 responses. 711 individuals (481 women aged 15-91 years and 230 men aged 15-85 years) admitted having had heterosexual intercourse. 75% had had more than one sex partner in the previous 5 years. 45% had had sex at least once with someone other than their regular partner. Multivariance analysis of variance of promiscuity and condom use revealed that men exhibited more risky sex practices than women (p .001), had more sex partners in the previous 5 years than women (p .01), had more single sexual encounters with other persons than the regular sex partner than women (p .001), and they used condoms less often than women (p .01). 119 respondents had experienced sexually transmitted diseases and 165 had taken HIV tests. The difference between men and women also showed up in terms of their ideas, perceptions, and feelings about condom use when the three theoretical models were considered (p .001). The variables used in the theory of planned behavior explained the variance in intended condom use for 36% of women and 43% of men. The health belief model explained intended condom use only for 15% of women and 32% of men, while the cost-benefit analysis explained it for 9% of women and 18% of men. The protection-motivation theory explained intended condom use variance for 32% of women and 41% of men, but not all variables were included in the model. Fear from AIDS was correlated with inquisitive behavior and with seriousness (both p .001). PMID:12291420

    Full Text Available Mobile banking is considered a new era in banking, in which banks are spending considerable amount of money to have it available to their customers and to cut their operations costs. The current exploratory study is an attempt to investigate the factors that influence Isfahanian’ intention to adopt mobile banking by extending the renowned framework of Decomposed Theory of Planned Behavior model (DTPB by additionally examining the effects of trust and perceived risk as components of attitude on behavioral intention. A self-administrated questionnaire had been developed and distributed in Isfahan city. Out of 400 questionnaires that have been distributed, 315 are returned (78.0%. Of these, five (5 responses had to be discarded due to invalid or incomplete data entries. Thus the sample comprising of a total of 310 respondents was used for analysis. The data was analyzed by AMOS software. Results of the study discovered that the decisive or crucial factors influencing mobile banking adoption are attitude and perceived behavioral control, However, social norms were the only factor found insignificant. The perceived usefulness, perceived ease of use ,compatibility, and trust under 'behavioral attitude' have positive effect on behavioral attitude; while perceived risk under 'behavioral attitude' has negative effect on behavioral attitude. the influence of the interpersonal influence under 'subjective norms' was also evident, while self-efficacy and facilitating condition under 'perceived behavioral control' are significant influential factors.

    Full Text Available The research aims were to identify the influence of attitude, subjective norms and perceived behavioral control on intention to buy, and effect of intention to buy and perceive behavioral control over buying behavior on processed body-shapping milk which added by supplement for body shaping. Research was conducted in Sleman Regency and design used was survey. Sampling was taken by using judgmental sampling method with criteria that were female, aged 18-25 yr old and was categorized as normal to overweight appearance. Respondents used were 100 undergraduate female students. Questionnaire was used as an instrument in order for data collecting to measure research variable that had been tested on validity and reliability. Analyses used were single and multiple linier regression. The results showed that only attitude and perceived behavioral control influenced (P<0.05 intention to buy in normal-weight group, while in over-weight group attitude, subjective norm and perceived behavioral control affected (P<0.001 attitude. Then, attitude and perceived behavioral control influenced buying behavior significantly both in normal and overweight. Therefore, it can be concluded that prediction capability of planned behavior theory are better when product relevancy to respondents was closed.

    The construction of a Gothic vault implied the solution of several technical challenges. The literature on Gothic vault construction is quite large and its growth continues steadily. The main challenge of any structure is that, during and after construction, it must be "safe", that is, it must not collapse. Indeed, it must be amply safe, able to support different loads for long periods of time. Masonry architecture has shown its structural safety for centuries or millennia. The Pantheon of Ro...

    2007-04-01

    Full Text Available Abstract Background This study was conceived to analyze how exercise and weight management psychosocial variables, derived from several health behavior change theories, predict weight change in a short-term intervention. The theories under analysis were the Social Cognitive Theory, the Transtheoretical Model, the Theory of Planned Behavior, and Self-Determination Theory. Methods Subjects were 142 overweight and obese women (BMI = 30.2 ± 3.7 kg/m2; age = 38.3 ± 5.8y, participating in a 16-week University-based weight control program. Body weight and a comprehensive psychometric battery were assessed at baseline and at program's end. Results Weight decreased significantly (-3.6 ± 3.4%, p Conclusion The present models were able to predict 20–30% of variance in short-term weight loss and changes in weight management self-efficacy accounted for a large share of the predictive power. As expected from previous studies, exercise variables were only moderately associated with short-term outcomes; they are expected to play a larger explanatory role in longer-term results.

    The theory of planned behaviour (TPB) has received its fair share of criticism lately, including calls for it to retire. We contribute to improving the theory by testing extensions such as the model of goal-directed behaviour (MGDB, which adds desire and anticipated positive and negative emotions) applied to physical activity (PA) intention. We also test the inclusion of a descriptive norm construct as an addition to the subjective norms construct, also applied to PA, resulting in two additio...

  18. Information theory-based approach for modeling the cognitive behavior of NPP operators

    International Nuclear Information System (INIS)

    An NPP system consists of three important components: the machine system, operators, and MMI. Through the MMI, operators monitor and control the plant system. The cognitive model of NPP operators has become a target of modeling by cognitive engineers due to their work environment: complex, uncertain, and safe critical. We suggested the contextual model for the cognitive behavior of NPP operator and the mathematical fundamentals based on information theory which can quantify the model. The demerit of the methodology using the information theory is that it cannot evaluate the correctness and quality of information. Therefore, the validation through the experiment is needed

  19. Personality, perceived environment, and behavior systems related to future smoking intentions among youths: an application of problem-behavior theory in Shanghai, China.

    Full Text Available Smoking among youths is a worldwide problem, particularly in China. Many endogenous and environmental factors influence smokers' intentions to smoke; therefore, a comprehensive model is needed to understand the significance and relationship of predictors. This study aimed to develop a prediction model based on problem-behavior theory (PBT to interpret intentions to smoke among Chinese youths.We conducted a cross-sectional study of 26,675 adolescents from junior, senior, and vocational high schools in Shanghai, China. Data on smoking status, smoking knowledge, attitude toward smoking, parents' and peers' smoking, and media exposure to smoking were collected from students. A structural equation model was used to assess the developed prediction model.The experimental smoking rate and current smoking rate among the students were 11.0% and 3%, respectively. Our constructed model showed an acceptable fit to the data (comparative fit index = 0.987, root-mean-square error of approximation = 0.034. Intention to smoke was predicted by perceived environment (β = 0.455, P 0.05 which consisted of acceptance of tobacco use (β = 0.668, P < 0.001 and academic performance (β = 0.171, P < 0.001.The PBT-based model we developed provides a good understanding of the predictors of intentions to smoke and it suggests future interventions among youths should focus on components in perceived environment and behavior systems, and take into account the moderating effects of personality system.
