  1. A Proof of the Geroch-Horowitz-Penrose Formulation of the Strong Cosmic Censor Conjecture Motivated by Computability Theory

    Science.gov (United States)

    Etesi, Gábor

    2013-03-01

    In this paper we present a proof of a mathematical version of the strong cosmic censor conjecture attributed to Geroch-Horowitz and Penrose but formulated explicitly by Wald. The proof is based on the existence of future-inextendible causal curves in causal pasts of events on the future Cauchy horizon in a non-globally hyperbolic space-time. By examining explicit non-globally hyperbolic space-times we find that in case of several physically relevant solutions these future-inextendible curves have in fact infinite length. This way we recognize a close relationship between asymptotically flat or anti-de Sitter, physically relevant extendible space-times and the so-called Malament-Hogarth space-times which play a central role in recent investigations in the theory of "gravitational computers". This motivates us to exhibit a more sharp, more geometric formulation of the strong cosmic censor conjecture, namely "all physically relevant, asymptotically flat or anti-de Sitter but non-globally hyperbolic space-times are Malament-Hogarth ones". Our observations may indicate a natural but hidden connection between the strong cosmic censorship scenario and the Church-Turing thesis revealing an unexpected conceptual depth beneath both conjectures.

  2. The Bieberbach conjecture

    Gong, Sheng

    2014-01-01

    In 1919, Bieberbach posed a seemingly simple conjecture. That "simple" conjecture challenged mathematicians in complex analysis for the following 68 years! In that time, a huge number of papers discussing the conjecture and its related problems were inspired. Finally in 1984, de Branges completed the solution. In 1989, Professor Gong wrote and published a short book in Chinese, The Bieberbach Conjecture, outlining the history of the related problems and de Branges' proof. The present volume is the English translation of that Chinese edition with modifications by the author. In particular, he includes results related to several complex variables. Open problems and a large number of new mathematical results motivated by the Bieberbach conjecture are included. Completion of a standard one-year graduate complex analysis course will prepare the reader for understanding the book. It would make a nice supplementary text for a topics course at the advanced undergraduate or graduate level.

    This paper reports the findings of motivational interviewing (MI) training with and without technology support on school-based health center (SBHC) providers' satisfaction with MI training, providers' self-report of behavioral counseling related to childhood overweight/obesity, and parents' perception of care after training. The effects of training and technology on MI is part of a larger comparative effectiveness, cluster randomized trial. Twenty-four SBHCs in six states received virtual training on MI. Half the sites received HeartSmartKids™, a bilingual (English/Spanish), decision-support technology. The technology generated tailored patient education materials. Standard growth charts were plotted and health risks were highlighted to support MI counseling. The results of the MI training included provider satisfaction with MI training and parent assessment of the components of MI in their child's care. Providers and parents were surveyed at baseline, after training, and six months after training. Providers were satisfied with training and reported improvements in counseling proficiency (ptechnology group reported significant improvement in provider support for healthy eating (p=0.04). Virtual training has the potential of preparing providers to use MI to address childhood obesity. Technology improved parent support for healthy eating. Future research should evaluate the impact of technology to support MI on patient outcomes. Childhood obesity guidelines emphasize that MI should be used to promote healthy weight in children. Training providers on MI may help more providers incorporate obesity guidelines in their practice. Copyright © 2017 Elsevier Inc. All rights reserved.

    Lanzagorta, Marco; Jitrik, Oliverio; Uhlmann, Jeffrey; Venegas-Andraca, Salvador E.

    2017-05-01

    In previous research we designed an interferometric quantum seismograph that uses entangled photon states to enhance sensitivity in an optomechanic device. However, a spatially-distributed array of such sensors, with each sensor measuring only nm-vibrations, may not provide sufficient sensitivity for the prediction of major earthquakes because it fails to exploit potentially critical phase information. We conjecture that relative phase information can explain the anecdotal observations that animals such as lemurs exhibit sensitivity to impending earthquakes earlier than can be done confidently with traditional seismic technology. More specifically, we propose that lemurs use their limbs as ground motion sensors and that relative phase differences are fused in the brain in a manner similar to a phased-array or synthetic-aperture radar. In this paper we will describe a lemur-inspired quantum sensor network for early warning of earthquakes. The system uses 4 interferometric quantum seismographs (e.g., analogous to a lemurs limbs) and then conducts phase and data fusion of the seismic information. Although we discuss a quantum-based technology, the principles described can also be applied to classical sensor arrays

    2008-01-01

    A conjecture of Fan and Raspaud [3] asserts that every bridgeless cubic graph con-tains three perfect matchings with empty intersection. Kaiser and Raspaud [6] sug-gested a possible approach to this problem based on the concept of a balanced join in an embedded graph. We give here some new results concerning this conjecture and prove that a minimum counterexample must have at least 32 vertices.

    This note confirms Goldbach’s Conjecture from 1742. This is, every even integer greater than two is the sum of two prime numbers. An analysis of the nature of multiplication as description length reduction for addition precedes a contraposition that it is impossible to subtract any prime from a given even integer without the result ever being prime.

  14. Motives to adopt renewable electricity technologies: Evidence from Sweden

    International Nuclear Information System (INIS)

    Bergek, Anna; Mignon, Ingrid

    2017-01-01

    The diffusion of renewable electricity technologies (RETs) has to speed up for countries to reach their, often ambitious, targets for renewable energy generation. This requires a large number of actors – including individuals, companies and other organizations – to adopt RETs. Policies will most likely be needed to induce adoption, but there is limited knowledge about what motivates RET adoption. The purpose of this paper is to complement and expand the available empirical evidence regarding motives to adopt RETs through a survey to over 600 RET adopters in Sweden. The main finding of the study is that there are many different motives to adopt RETs and that RET adopters are a heterogeneous group with regard to motives. Although environmental concerns, interest in the technology, access to an RE resource and prospects to generate economic revenues are important motives in general, adopters differ with regard to how large importance they attach to the same motive and each adopter can also have several different motives to adopt. There are also differences in motives between adopter categories (especially independent power producers vs. individuals and diversified companies) and between RETs (especially wind power vs. solar power). This implies that a variety of policy instruments might be needed to induce further adoption of a variety of RETs by a variety of adopter categories. - Highlights: • There are many different motives to adopt renewable electricity technologies (RETs). • Adopters attach different levels of importance to the same motive. • Adopters can have several different motives to adopt a particular RET. • Motives to adopt RETs differ between wind power, solar PV and small-scale hydro. • Motives to adopt RETs differ between IPPs, individuals and diversified companies.

    Full Text Available In language classrooms, being in unnatural conversational situations, students need motivation more than other learning milieus. Teachers try to capture the attention of students through various methods and techniques. Many researchers in EFL teaching profession have stated that good motivation has appositive effect on foreign language learning. The purpose of this study is to explore how technology could be used to increase students’ motivation in EFL classrooms. For this purpose; a questionnaire was administered to a group of students at Akdeniz University Preparatory Classes in 2007-2008 academic year. As a result it was found out that technology was a dynamic and challenging motivating factor in EFL classrooms and there may be some suggestions focusing on the achievement of learning objectives.

    2013-12-01

    Full Text Available This study investigated what motivates Brazilian academic researchers to get involved in University-Industry Technology Transfer (UITT and deterrents to contributing to this process. The research relied on interviews with experienced academic scientists and managers from four universities in Brazil. Determination, persistence and entrepreneurship, related to motivational types Self-direction and Stimulation, were prominent. Hedonism, Achievement and Power - highlighting a shift in their professional identity - were also observed. Universalism type involved opening career opportunities, awakening and maintaining the interest of students. The major motivational goals were: generate resources, solve problems, professional challenge, personal gains, personal gratification, academic prestige, competition, and solving problems of society. Factors that discouraged researchers were: time required for UITT, lack of incentive, innovation environment, and fear of contravening university rules, among others. Knowledge of motivational profiles of academic scientists favors the development of incentive policies and programs for UITT, helping to attract and retain qualified researchers at Brazilian universities.

    Science.gov (United States)

    Gaul, Sylvia; Ziefle, Martina

    In this research we examine the generation specific acceptance motives of eHealth technologies in order to assess the likelihood of success for these new technologies. 280 participants (14 - 92 years of age) volunteered to participate in a survey, in which using motives and barriers toward smart home technologies were explored. The scenario envisaged was the use of a medical stent implemented into the body, which monitors automatically the health status and which is able to remotely communicate with the doctor. Participants were asked to evaluate the pros and cons of the usage of this technology, their acceptance motives and potential utilization barriers. In order to understand the complex nature of acceptance, personal variables (age, technical expertise, health status), individual's cognitive concepts toward ageing as well as perceived usefulness were related. Outcomes show that trust, believe in the reliability of technology, privacy and security as well as intimacy facets are essential for acceptance and should be considered in order to proactively design a successful rollout of smart home technologies.

    2013-01-01

    Full Text Available Information and Communication Technologies Action Competence (ICTAC can be defined as “individuals’ motivation and capacity to voluntarily employ their ICT skills for initiating or taking part in civic actions”. Since academic staff and teachers in ICT related fields have crucial roles in training action-competent individuals, this study aimed to determine the views of preservice teachers and instructors in Computer Education and Instructional Technology (CEIT departments about the motivating and hindering factors regarding ICTAC. Researchers used purposeful sampling technique and identified seven instructors and 16 students attending outlier CEIT departments from four different Turkish state universities. Since there is no contemporary framework on factors motivating or hindering ICTAC, the study was conducted with a qualitative approach and the data were collected through semi-structured interviews. Factors motivating and hindering ICTAC were identified through a content analysis. Findings of the study are believed to guide ICT and ICT education professionals in training students with higher levels of ICTAC and guide the course developers to focus on relevant social responsibility issues

  8. On the application of motivation theory to human factors/ergonomics: motivational design principles for human-technology interaction.

    Science.gov (United States)

    Szalma, James L

    2014-12-01

    Motivation is a driving force in human-technology interaction. This paper represents an effort to (a) describe a theoretical model of motivation in human technology interaction, (b) provide design principles and guidelines based on this theory, and (c) describe a sequence of steps for the. evaluation of motivational factors in human-technology interaction. Motivation theory has been relatively neglected in human factors/ergonomics (HF/E). In both research and practice, the (implicit) assumption has been that the operator is already motivated or that motivation is an organizational concern and beyond the purview of HF/E. However, technology can induce task-related boredom (e.g., automation) that can be stressful and also increase system vulnerability to performance failures. A theoretical model of motivation in human-technology interaction is proposed, based on extension of the self-determination theory of motivation to HF/E. This model provides the basis for both future research and for development of practical recommendations for design. General principles and guidelines for motivational design are described as well as a sequence of steps for the design process. Human motivation is an important concern for HF/E research and practice. Procedures in the design of both simple and complex technologies can, and should, include the evaluation of motivational characteristics of the task, interface, or system. In addition, researchers should investigate these factors in specific human-technology domains. The theory, principles, and guidelines described here can be incorporated into existing techniques for task analysis and for interface and system design.

  9. Involutions and the Jacobian conjecture

    OpenAIRE

    2014-01-01

    The famous Jacobian conjecture asks if an endomorphism $f$ of $K[x,y]$ ($K$ is a characteristic zero field) having a non-zero scalar Jacobian is invertible. Let $\\alpha$ be the exchange involution on $K[x,y]$: $\\alpha(x)= y$ and $\\alpha(y)= x$. An $\\alpha$-endomorphism $f$ of $K[x,y]$ is an endomorphism of $K[x,y]$ that preserves the involution $\\alpha$: $f \\alpha= \\alpha f$. It was shown that if $f$ is an $\\alpha$-endomorphism of $K[x,y]$ having a non-zero scalar Jacobian, then $f$ is invert...

  10. Weak gravity conjecture and effective field theory

    Science.gov (United States)

    Saraswat, Prashant

    2017-01-01

    The weak gravity conjecture (WGC) is a proposed constraint on theories with gauge fields and gravity, requiring the existence of light charged particles and/or imposing an upper bound on the field theory cutoff Λ . If taken as a consistency requirement for effective field theories (EFTs), it rules out possibilities for model building including some models of inflation. I demonstrate simple models which satisfy all forms of the WGC, but which through Higgsing of the original gauge fields produce low-energy EFTs with gauge forces that badly violate the WGC. These models illustrate specific loopholes in arguments that motivate the WGC from a bottom-up perspective; for example the arguments based on magnetic monopoles are evaded when the magnetic confinement that occurs in a Higgs phase is accounted for. This indicates that the WGC should not be taken as a veto on EFTs, even if it turns out to be a robust property of UV quantum gravity theories. However, if the latter is true, then parametric violation of the WGC at low energy comes at the cost of nonminimal field content in the UV. I propose that only a very weak constraint is applicable to EFTs, Λ ≲(log 1/g )-1 /2Mpl , where g is the gauge coupling, motivated by entropy bounds. Remarkably, EFTs produced by Higgsing a theory that satisfies the WGC can saturate but not violate this bound.

  16. Motivation.

    Science.gov (United States)

    Chambers, David W

    2007-01-01

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

    Happonen, Ari; Stepanov, Alexander; Hirvimäki, Marika; Manninen, Matti; Dennisuk, William; Piili, Heidi; Salminen, Antti

    This study is based on observed outcomes of motivation sources and collaboration elements from a living lab style co-operation project. In this project, researchers of engineering science and an individual artist co-operated closely. The goal was to create an artwork made from corrugated board by utilizing laser cutting technology. In the context of this study, the scientist and the artist participated in the whole process and the research was done in living lab style arrangement. The research process integrated multiple experts from different scientific fields and experts from practical contexts to develop a new art design and art forming process with utilization of laser cutting technology. The purpose of this study was to find out and discuss about the key elements for high motivation to work together and then reveal the best practice findings in this co-operative development process. Elements were studied from three different points of view: artists view, collaboration motivation view and practical cutting point of view. The elements were analysed by utilizing an active documentation collection methodology, during the whole process, and by using story-telling methodology. The documents were used to reflect facts and feelings from the co-operation, the work process and the challenges encountered within collaboration. This article contributes to research methodology and best practice context by revealing the key elements, which build the motivation compelling (as personal inner motivation) the participant to work out of office hours as well as on weekends. Furthermore, as the artist-engineer co-operation is not frequently reported in scientific literature, this study reveals valuable information for practitioners and co-operation researchers.

  19. Axion monodromy and the weak gravity conjecture

    International Nuclear Information System (INIS)

    Hebecker, Arthur; Rompineve, Fabrizio; Westphal, Alexander

    2015-12-01

    Axions with broken discrete shift symmetry (axion monodromy) have recently played a central role both in the discussion of inflation and the 'relaxion' approach to the hierarchy problem. We suggest a very minimalist way to constrain such models by the weak gravity conjecture for domain walls: While the electric side of the conjecture is always satisfied if the cosine-oscillations of the axion potential are sufficiently small, the magnetic side imposes a cutoff, Λ 3 ∝mfM pl , independent of the height of these 'wiggles'. We compare our approach with the recent related proposal by Ibanez, Montero, Uranga and Valenzuela. We also discuss the non-trivial question which version, if any, of the weak gravity conjecture for domain walls should hold. In particular, we show that string compactifications with branes of different dimensions wrapped on different cycles lead to a 'geometric weak gravity conjecture' relating volumes of cycles, norms of corresponding forms and the volume of the compact space. Imposing this 'geometric conjecture', e.g. on the basis of the more widely accepted weak gravity conjecture for particles, provides at least some support for the (electric and magnetic) conjecture for domain walls.

    and motivation when designing the digital museum installations. Our conceptualization of motives and motivation is based on Cultural-Historical Theory and especially the work of Vygotsky (1982) and Hedegaard (2002) as these perspectives capture the dynamics of motivation as it develops in context.......We explore the concepts of motivation and motives in relation to inform the design of digital interactive technologies for museum exhibitions. A central issue for museums is to create strong links between the subject matter knowledge and the everyday life of the children. Pursuing such an agenda...... spaces are more successful than others in spurring this engagement. We suggest that digital technology can potentially support this “double move” in which subject matter knowledge is naturally integrated into the children’s everyday life if designers take into consideration the hierarchy of motives...

    Hod, Shahar

    The weak gravity conjecture suggests that, in a self-consistent theory of quantum gravity, the strength of gravity is bounded from above by the strengths of the various gauge forces in the theory. In particular, this intriguing conjecture asserts that in a theory describing a U(1) gauge field coupled consistently to gravity, there must exist a particle whose proper mass is bounded (in Planck units) by its charge: m/mP attracted the attention of physicists and mathematicians over the last decade. It should be emphasized, however, that despite the fact that there are numerous examples from field theory and string theory that support the conjecture, we still lack a general proof of its validity. In the present paper, we prove that the weak gravity conjecture (and, in particular, the mass-charge upper bound m/mP law of thermodynamics, a law which is widely believed to reflect a fundamental aspect of the elusive theory of quantum gravity.

    Full Text Available The article describes problems encountered by administrative and teaching staff in higher education concerning development of distance learning. One of such problems is motivating teaching staff to produce and implement electroniс technologies in educational process. Here we describe efforts to develop distance learning methods as in the Amur State University. The author analyzed general motivation issues and motivation of faculty members for implementing distance learning methodsin psychological literature. Based on the method offered by N. V. Nemova, the author marks the following motives of the faculty: the motive of creative self-actualization in professional activity, the motive of personal development, acquisition of new information, the motive of self-affirmation, attaining social success, the sense of belonging to the team, the motive of stability, safety, and the motive of competition. Based on the academic literature analysis we offered some methods for stimulating motives, such as: stimulating the high level of teacher’s independence that is displaying in the ability to work on the targeted program; enabling teachers to take career enhancement training on electronic distance learning technologies; enabling teachers to share experience during conferences, pedagogical reading and seminars; joining various agencies, which promote distance learning in higher education; providing remuneration for methodological work; providing methodological support for different contests in e-learning. The study of the faculty attitudes and motivation to distance learning in higher education is necessary to determine the stimulation means of faculty activity that helps achieving better results.

    Full Text Available Considerable discussion has taken place in practice and academe regarding the need for changes to the educational system to better suit current student’s approaches and preferences for technology use in learning. Much of this discussion involves assumptions about the current students (referred to by some as ‘digital natives’ preference for independent learning and that students are motivated in similar ways to use technology to achieve and support their preferred learning style. This study sought to better understand student’s motivations for technology use in learning and whether assumptions about the homogeneity of motivations are warranted. We sought to identify students’ motivation typology and any groupings within these typologies, and understand the inter-relationship between motivations. Using data collected from 16 Information Systems (IS students via the Repertory Grid Interview technique (RGT, a cluster analysis segmented respondents into two distinct groups: ‘Independent Learners’ and ‘Traditional Learners’. A hierarchical framework of technology use motivations was developed for each group using Interpretive Structural Modelling (ISM and Cross-impact Matrix Multiplication Applied to Classification (MICMAC was used to categorise each group’s motivation factors. Results show that the two groups were driven to achieve the same learning goals by different paths and hence questioning the assumption of homogeneity in technology use motivations among the current student cohort.

  7. Motivating Information Technology Professionals: The case of New Zealand

    2017-06-01

    Full Text Available IT professionals play a critical role in organizations. Research indicates that they may be unique in their attitudes toward motivation and job satisfaction. In New Zealand, a shortage of skilled professionals may contribute to or impact on motivation. Using a modified model of Herzberg’s two-factor theory by Smerek and Peterson (2007, this research seeks to answer the question: what motivates New Zealand IT professionals? In response, an online questionnaire was distributed to a population of New Zealand IT professionals and the data analysed using Partial Least Squares to understand the relationship between the various dimensions of job satisfaction, the impact of personal and job characteristics, and turnover intention. The findings show that the New Zealand IT professional is primarily motivated by the nature of his or her work, followed by perceptions of responsibility, and how supervisors encourage an environment for such. Satisfaction with salary is a predictor to a lesser degree. Perhaps somewhat surprisingly, professional growth opportunities, career advancement, and recognition do not have a statistically-significant positive association with motivation. We conclude that, to motivate their IT workforce, organizations should: 1 focus on the nature of the jobs that IT professionals undertake; 2 train supervisors to provide an empowering environment; 3 offer competitive salaries to retain top talent; 4 not hesitate to employ IT professionals born outside New Zealand; and 5 take account of the singularities of the New Zealand labour market in seeking to attract, recruit and retain IT professionals. Implications for policy, practice and theory are discussed.

  9. The 1 , 2 , 3-Conjecture And 1 , 2-Conjecture For Sparse Graphs

    Directory of Open Access Journals (Sweden)

    Cranston Daniel W.

    2014-11-01

    Full Text Available The 1, 2, 3-Conjecture states that the edges of a graph without isolated edges can be labeled from {1, 2, 3} so that the sums of labels at adjacent vertices are distinct. The 1, 2-Conjecture states that if vertices also receive labels and the vertex label is added to the sum of its incident edge labels, then adjacent vertices can be distinguished using only {1, 2}. We show that various configurations cannot occur in minimal counterexamples to these conjectures. Discharging then confirms the conjectures for graphs with maximum average degree less than 8/3. The conjectures are already confirmed for larger families, but the structure theorems and reducibility results are of independent interest.

    Bell, Jason P; Tucker, Thomas J

    2016-01-01

    The Dynamical Mordell-Lang Conjecture is an analogue of the classical Mordell-Lang conjecture in the context of arithmetic dynamics. It predicts the behavior of the orbit of a point x under the action of an endomorphism f of a quasiprojective complex variety X. More precisely, it claims that for any point x in X and any subvariety V of X, the set of indices n such that the n-th iterate of x under f lies in V is a finite union of arithmetic progressions. In this book the authors present all known results about the Dynamical Mordell-Lang Conjecture, focusing mainly on a p-adic approach which provides a parametrization of the orbit of a point under an endomorphism of a variety.

    2014-01-01

    In 1920, Pierre Fatou expressed the conjecture that--except for special cases--all critical points of a rational map of the Riemann sphere tend to periodic orbits under iteration. This conjecture remains the main open problem in the dynamics of iterated maps. For the logistic family x- ax(1-x), it can be interpreted to mean that for a dense set of parameters ""a,"" an attracting periodic orbit exists. The same question appears naturally in science, where the logistic family is used to construct models in physics, ecology, and economics. In this book, Jacek Graczyk and Grzegorz Swiatek provi

    This research is operationally aimed to obtain the result of analysis and interpretation about: relationship of achievement motive, compensation with performance at a junior high school in Manado, Indonesia. This research applies a quantitative approach with correlation analysis method. The research was conducted at one junior high school in Manado, Indonesia. The results showed achievement motive at the school teachers is quite high. This result means that, generally, the teachers of the school have a desire to improve achievement; the performance at the school is good enough. This result means that in general, the performance of teachers at the school is increasing, there is a linkage degree and determinative power between the achievement motive with the performance of teachers at the school amounted 0.773% or 77.3%, compensation for the school teachers in Manado is good enough. This result means that the compensation received is satisfactory, there is a linkage degree and determinative power between compensation and performance of the school teachers in Manado amounted to 0.582 or 58.2%.

  14. The Effects of Embedding Information Technologies within ELT on EFL Learners’ Motivation and Interest

    2014-01-01

    Full Text Available In today’s globalised world, technologies have been embedded in every aspect of daily activities and discourses. The field of education made no exception and hence technologies have become an integral part of all educational systems worldwide, but with different levels and layers. The presence of information technology in English language teaching has brought about notable changes for teachers and learners alike. Accordingly, this paper investigates the impact of integrating information technologies in ELT on EFL learners’ motivation and interest. Based on an authentic comparative case study, this paper explores the influence of information technology on EFL learners’ perceptions, motivation, and interest in the context of ELT in the Tunisian higher education. The findings of this study suggest that the integration of IT in ELT heavily affects EFL students’ motivation and academic performance and hence EFL instructors should take this variable into consideration.

    2014-05-01

    Background:Few studies have examined students' attitudinal perceptions of technology. There is no appropriate instrument to measure senior high school students' motivation and self-regulation toward technology learning among the current existing instruments in the field of technology education. Purpose:The present study is to validate an instrument for assessing senior high school students' motivation and self-regulation towards technology learning. Sample:A total of 1822 Taiwanese senior high school students (1020 males and 802 females) responded to the newly developed instrument. Design and method:The Motivation and Self-regulation towards Technology Learning (MSRTL) instrument was developed based on the previous instruments measuring students' motivation and self-regulation towards science learning. Exploratory and confirmatory factor analyses were utilized to investigate the structure of the items. Cronbach's alpha was applied for measuring the internal consistency of each scale. Furthermore, multivariate analysis of variance was used to examine gender differences. Results:Seven scales, including 'Technology learning self-efficacy,' 'Technology learning value,' 'Technology active learning strategies,' 'Technology learning environment stimulation,' 'Technology learning goal-orientation,' 'Technology learning self-regulation-triggering,' and 'Technology learning self-regulation-implementing' were confirmed for the MSRTL instrument. Moreover, the results also showed that male and female students did not present the same degree of preference in all of the scales. Conclusions:The MSRTL instrument composed of seven scales corresponding to 39 items was shown to be valid based on validity and reliability analyses. While male students tended to express more positive and active performance in the motivation scales, no gender differences were found in the self-regulation scales.

    In actual electricity market, which operates repeatedly on the basis of one hour or half hour, each firm might learn or estimate other competitors' strategic behaviors from available historical market operation data, and rationally aims at its maximum profit in the repeated biddings. A conjectural variation based learning method is proposed in this paper for generation firm to improve its strategic bidding performance. In the method, each firm learns and dynamically regulates its conjecture upon the reactions of its rivals to its bidding according to available information published in the electricity market, and then makes its optimal generation decision based on the updated conjectural variation of its rivals. Through such learning process, the equilibrium reached in the market is proven a Nash equilibrium. Motivation of generation firm to learn in the changing market environment and consequence of learning behavior in the market are also discussed through computer tests. (author)

  5. Are managerial pressure, technological control and intrinsic motivation effective in improving data quality?

    International Nuclear Information System (INIS)

    Molina, Roger; Unsworth, Kerrie; Hodkiewicz, Melinda; Adriasola, Elisa

    2013-01-01

    Can data collectors be “pushed” into collecting high quality data or would being “pulled” be more effective? This paper finds that managers should be careful of the degree to which “push” factors, such as managerial pressure and technological input control, are relied upon. While they may be helpful for motivating those data collectors who are not intrinsically motivated, they are either not helpful or may discourage those data collectors who are intrinsically motivated. Instead, self-concordance may act as a longer-term, more stable approach to increasing the motivation of data collectors and thus increasing the quality of data that enter reliability systems. This study uses a sequential mixed-method approach involving interviews with 20 data collectors and a quantitative survey of 109 data collectors in a water utility. It examines the interactive effect of managerial pressure, technological input control and self-concordance on data collection performance

    2016-01-15

    In the work of Paulsen et al. [J. Funct. Anal. (in press); preprint arXiv:1407.6918], the concept of synchronous quantum correlation matrices was introduced and these were shown to correspond to traces on certain C*-algebras. In particular, synchronous correlation matrices arose in their study of various versions of quantum chromatic numbers of graphs and other quantum versions of graph theoretic parameters. In this paper, we develop these ideas further, focusing on the relations between synchronous correlation matrices and microstates. We prove that Connes’ embedding conjecture is equivalent to the equality of two families of synchronous quantum correlation matrices. We prove that if Connes’ embedding conjecture has a positive answer, then the tracial rank and projective rank are equal for every graph. We then apply these results to more general non-local games.

  9. Probing the CORE of the Haldane conjecture

    1997-09-01

    The Contractor Renormalization group method (CORE), originally developed for application to lattice gauge theories, is very well adapted to the study of spin systems and systems with fermions. As a warmup exercise for studying Hubbard models this method is applied to spin-1/2 and spin-1 anti-ferromagnets in one space dimension in order to see if it is able to explain the physics of the Haldane conjecture. The method not only provides support for Haldane's conjecture but provides insight int the physics of a more general class of spin-1 systems with Hamiltonians of the form H = {summation}{sub j} {rvec s}(j) {center_dot} {rvec s}(j + 1) - {beta}({rvec s}(j) {center_dot} {rvec s}(j+1)){sup 2} about which, until now, little was known.

    Woolgar, Eric [Dept. of Mathematical and Statistical Sciences andTheoretical Physics Institute, University of Alberta,Edmonton, AB, T6G 2G1 (Canada)

    2017-03-20

    The new positive energy conjecture was first formulated by Horowitz and Myers in the late 1990s to probe for a possible extended, nonsupersymmetric AdS/CFT correspondence. We consider a version formulated for complete, asymptotically Poincaré-Einstein Riemannian metrics (M,g) with bounded scalar curvature R≥−n(n−1) and with no (inner) boundary except possibly a finite union of compact, totally geodesic hypersurfaces (horizons). This version then asserts that any such (M,g) must have mass not less than a certain bound which is realized as the mass m{sub 0} of a metric g{sub 0} induced on a time-symmetric slice of a spacetime called an AdS soliton. This conjecture remains unproved, having so far resisted standard techniques. Little is known other than that the conjecture is true for metrics which are sufficiently small perturbations of g{sub 0}. We pose another test for the conjecture. We assume its validity and attempt to prove as a corollary the corresponding scalar curvature rigidity statement, which is that g{sub 0} is the unique asymptotically Poincaré-Einstein metric with mass m{sub 0} obeying R≥−n(n−1). Were a second such metric g{sub 1} not isometric to g{sub 0} to exist, it then may well admit perturbations of lower mass, contradicting the assumed validity of the conjecture. We find enough rigidity to show that the minimum mass metric must be static Einstein, so the problem is reduced to that of static uniqueness. When n=3 the manifold must be isometric to a time-symmetric slice of an AdS soliton spacetime, or must have a non-compact horizon. En route we study the mass aspect, obtaining and generalizing known results: (i) we relate the mass aspect of static metrics to the holographic energy density, (ii) we obtain the conformal invariance of the mass aspect when the bulk dimension is odd, and (iii) we show the vanishing of the mass aspect for negative Einstein manifolds with Einstein conformal boundary.

  20. Influence of science and technology magnet middle schools on students' motivation and achievement in science

    Science.gov (United States)

    Allen, David

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

    Full Text Available A graph is said to be reconstructible if it is determined up to isomor- phism from the collection of all its one-vertex deleted unlabeled subgraphs. Reconstruction Conjecture (RC asserts that all graphs on at least three vertices are reconstructible. In this paper, we prove that interval-regular graphs and some new classes of graphs are reconstructible and show that RC is true if and only if all non-geodetic and non-interval-regular blocks G with diam(G = 2 or diam(Ḡ = diam(G = 3 are reconstructible

    Full Text Available Technology mediated learning brings together the users with shared interests. This method makes learners informally engaged in language learning. This study intended to investigate the effect of technology mediated instruction on cognitive scaffolding, academic performance and motivation. Employing a quasi-experimental research, 80 learners from two intact classes at Islamic Azad University, Osku Branch were selected as the experimental and control groups. Telegram as a tool was used in the experimental group, while the control group received traditional way of instruction. Critical ethnography approach was implemented to consider the amount of cognitive scaffolding. To measure the students’ motivational level in both groups, Course Interest Survey (CIS was administered at the end of the semester. The total average score for each group was calculated. To compare students’ academic achievement, their average scores in the final academic test were considered. An Independent samples t-test in was used to compare the mean scores. The results indicated that technology mediated learning brought about cognitive scaffolding and the students in the experimental group outperformed the control group in terms of motivation and academic achievement. The results of the study suggest that to bring about academically successful students, practitioners should use technology mediated instruction.

    Full Text Available Abstract Study abroad culture is constantly changing (Kinginger, 2013, involving new challenges such as easier access to the first language culture via technology. There has been little research done on technology use abroad and its relationship with both linguistic gains (Coleman & Chafer, 2010; Kelly, 2010 and motivation (Allen, 2013; Irie & Ryan, 2015. To explore the role of motivation in developing a successful study abroad culture in the digital age, we documented technology use in the first language and second language of 15 college students during their summer sojourn in Argentina. We quantitatively evaluated participants’ motivation (Gardner, 1985; Ushida, 2003 and proficiency (Seibert Hanson & Carlson, 2014, and qualitatively analyzed their responses to open-ended questions about goals and culture shock. We found that higher motivation levels were correlated with greater linguistic gains and less technology use in the first language (specifically internet-related. Lower motivation levels matched increased technology use in the first language, and perceptions of failure to achieve study abroad goals and integrate into the host culture.

    We study weakly coupled U(1) theories in AdS{sub 3}, their associated charged BTZ solutions, and their charged spectra. We find that modular invariance of the holographic dual two-dimensional CFT and compactness of the gauge group together imply the existence of charged operators with conformal dimension significantly below the black hole threshold. We regard this as a form of the Weak Gravity Conjecture (WGC) in three dimensions. We also explore the constraints posed by modular invariance on a particular discrete ℤ{sub N} symmetry which arises in our discussion. In this case, modular invariance does not guarantee the existence of light ℤ{sub N}-charged states. We also highlight the differences between our discussion and the usual heuristic arguments for the WGC based on black hole remnants.

  6. Understanding and motivating health care employees: integrating Maslow's hierarchy of needs, training and technology.

    Science.gov (United States)

    Benson, Suzanne G; Dundis, Stephen P

    2003-09-01

    This paper applies Maslow's Hierarchy of Needs Model to the challenges of understanding and motivating employees in a rapidly changing health care industry. The perspective that Maslow's Model brings is an essential element that should be considered as the health care arena is faced with reorganization, re-engineering, mergers, acquisitions, increases in learning demands, and the escalating role of technology in training. This paper offers a new perspective related to how Maslow's Model, as used in business/organizational settings, can be directly related to current workforce concerns: the need for security and freedom from stress, social belongingness, self-esteem, self-actualization, altered work/social environments, and new opportunities for learning and self-definition. Changes in health care will continue at an accelerated pace and with these changes will come the need for more and more training. The use of technology in training has heightened access, faster distribution, innovation and increased collaboration. However, with this technology come attendant challenges including keeping up with the technology, the increased pace of training, depersonalization, and fear of the unknown. The Maslow model provides a means for understanding these challenges in terms of universal individual needs. How does one motivate employees in the face of increased demands, particularly when they are being asked to meet these demands with fewer resources? The answer is, in large part, to make the employee feel secure, needed, and appreciated. This is not at all easy, but if leaders take into consideration the needs of the individual, the new technology that provides challenges and opportunities for meeting those needs, and provides the training to meet both sets of needs, enhanced employee motivation and commitment is possible.

    2011-01-01

    The aim of this study was to analyze the motives, enablers, and barriers to promote or initiate health technology assessment (HTA) in different contexts. An observational study design was used to address the above question that included a survey questionnaire and a two-phase study. The respondents for the questionnaire and first round of the study were from HTA agencies of high income countries and those low and middle income countries that have managed to establish HTA agencies (n = 50), that are members of International Network of Agencies for Health Technology Assessment (INAHTA), EuroScan, or European network for Health Technology Assessment (EUnetHTA). The second round of the study was exclusively with respondents from low and middle income countries that were manly affiliated to Health Technology Assessment International (HTAi) interest subgroup for low and middle income countries and aimed to initiate HTA activities (n = 34). Forty-one of fifty HTA agencies answered the survey questionnaire. Thirty-three of fifty individuals belonging to HTA agencies from high income countries and sixteen of thirty-four individuals from low and middle income countries answered in the first and second phases of the study, respectively. In the promotion and/or initiation of HTA, the top three motives were the same for both high income and low and middle income countries. The top three enablers were also similar but the prioritization varies. The top three barriers were more context specific. HTA promotion or initiation is influenced by the following: (i) key players that affect the time taken to establish HTA agencies; (ii) three models for HTA promotion and initiation: top-down (political interest), bottom-up (academic/research interest), and converging (political and academic/research interests); and (iii) motives, enablers, and barriers at the local context.

    2009-06-01

    A case study is described of the redesign of an assessment task - the writing of an Optoelectronic Technology profile - to achieve improved outcomes in student education and capability development, in particular, research skills. Attention is drawn to the value of a formally scheduled discussion between teacher and student around controlling the scope of the profile via an appropriately constructed "brief", and the selection and evaluation of the reference resources to be used in completing the task. Student motivation is improved through "student publishing" and encouraging students to regard their technology profile as an example of their work that can be shown to potential employers, possibly as part of a portfolio. Students have the choice as to whether they will also use the technology profile task as a vehicle to develop teamwork experience and skills.

  14. Relaxion monodromy and the Weak Gravity Conjecture

    International Nuclear Information System (INIS)

    Ibáñez, L.E.; Montero, M.; Uranga, A.M.; Valenzuela, I.

    2016-01-01

    The recently proposed relaxion models require extremely large trans-Planckian axion excursions as well as a potential explicitly violating the axion shift symmetry. The latter property is however inconsistent with the axion periodicity, which corresponds to a gauged discrete shift symmetry. A way to make things consistent is to use monodromy, i.e. both the axion and the potential parameters transform under the discrete shift symmetry. The structure is better described in terms of a 3-form field C μνρ coupling to the SM Higgs through its field strength F 4 . The 4-form also couples linearly to the relaxion, in the Kaloper-Sorbo fashion. The extremely small relaxion-Higgs coupling arises in a see-saw fashion as g≃F 4 /f, with f being the axion decay constant. We discuss constraints on this type of constructions from membrane nucleation and the Weak Gravity Conjecture. The latter requires the existence of membranes, whose too fast nucleation could in principle drive the theory out of control, unless the cut-off scale is lowered. This allows to rule out the simplest models with the QCD axion as relaxion candidate on purely theoretical grounds. We also discuss possible avenues to embed this structure into string theory.

  15. Interpreting multiple dualities conjectured from superconformal index identities

    CERN Document Server

    Khmelnitsky, A

    2010-01-01

    We consider field theory side of new multiple Seiberg dualities conjectured within superconformal index matching approach. We study the case of SU(2) supersymmetric QCD and find that the numerous conjectured duals are different faces of handful of master theories. These different faces are inequivalent to each other in a very peculiar sense. Some master theories are fully known; we construct superpotentials for others. We confirm that all index identities correspond to theories flowing to one and the same theory in the infrared, thus supporting the conjecture of index matching for Seiberg dual theories. However, none of the index identities considered in this paper actually implies an entirely new, unknown duality.

    Gauge-flation, inflation from non-Abelian gauge fields, was introduced in [1, 2]. In this work, we study the cosmic no-hair conjecture in gauge-flation. Starting from Bianchi-type I cosmology and through analytic and numeric studies we demonstrate that the isotropic FLRW inflation is an attractor of the dynamics of the theory and that the anisotropies are damped within a few e-folds, in accord with the cosmic no-hair conjecture.

  4. Driving with advanced vehicle technology: A qualitative investigation of older drivers' perceptions and motivations for use.

    2017-09-01

    For older drivers, in-vehicle technology offers much potential to improve safety and increase longevity of retaining both licensure and community mobility. However, little is known about how older drivers perceive Advanced Vehicle Technologies (AVTs) based on everyday driving experience. Interviews with 35 older drivers (20 men; 15 women) aged 60-85 who owned a vehicle with at least two AVTs (e.g., back-up camera, lane departure warning) were conducted to explore the meanings that older drivers assigned to AVTs and motivations for use, including whether age-related functional changes were part of their automobile purchase decision. Findings indicate that age-related changes are not a primary reason for why older adults seek out AVTs, but they still perceived and experienced AVTs to counteract age-related changes in driving performance based upon changes they felt occurring within the body. Older drivers also described AVTs as generating a sense of comfort behind-the-wheel. Comfort with this technology was equated with convenience, ease of use, and increased feelings of safety. Discussion emphasizes how assessments of the quality of driving performance and value of technology occur in relation to an aging body. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2016-01-01

    This chapter studies the bidirectional causal interactions between curiosity and learning and discusses how understanding these interactions can be leveraged in educational technology applications. First, we review recent results showing how state curiosity, and more generally the experience of novelty and surprise, can enhance learning and memory retention. Then, we discuss how psychology and neuroscience have conceptualized curiosity and intrinsic motivation, studying how the brain can be intrinsically rewarded by novelty, complexity, or other measures of information. We explain how the framework of computational reinforcement learning can be used to model such mechanisms of curiosity. Then, we discuss the learning progress (LP) hypothesis, which posits a positive feedback loop between curiosity and learning. We outline experiments with robots that show how LP-driven attention and exploration can self-organize a developmental learning curriculum scaffolding efficient acquisition of multiple skills/tasks. Finally, we discuss recent work exploiting these conceptual and computational models in educational technologies, showing in particular how intelligent tutoring systems can be designed to foster curiosity and learning. © 2016 Elsevier B.V.

    In general relativity, gravitational collapse of matter fields ends with the formation of a spacetime singularity, where the matter density becomes infinite and standard physics breaks down. According to the weak cosmic censorship conjecture, singularities produced in the gravitational collapse cannot be seen by distant observers and must be hidden within black holes. The validity of this conjecture is still controversial and at present we cannot exclude that naked singularities can be created in our Universe from regular initial data. In this paper, we study the radiation emitted by a collapsing cloud of dust and check whether it is possible to distinguish the birth of a black hole from the one of a naked singularity. In our simple dust model, we find that the properties of the radiation emitted in the two scenarios is qualitatively similar. That suggests that observational tests of the cosmic censorship conjecture may be very difficult, even in principle. (orig.)

  11. Periods and Nori motives

    CERN Document Server

    Huber, Annette

    2017-01-01

    This book casts the theory of periods of algebraic varieties in the natural setting of Madhav Nori’s abelian category of mixed motives. It develops Nori’s approach to mixed motives from scratch, thereby filling an important gap in the literature, and then explains the connection of mixed motives to periods, including a detailed account of the theory of period numbers in the sense of Kontsevich-Zagier and their structural properties. Period numbers are central to number theory and algebraic geometry, and also play an important role in other fields such as mathematical physics. There are long-standing conjectures about their transcendence properties, best understood in the language of cohomology of algebraic varieties or, more generally, motives. Readers of this book will discover that Nori’s unconditional construction of an abelian category of motives (over fields embeddable into the complex numbers) is particularly well suited for this purpose. Notably, Kontsevich's formal period algebra represents a to...

    A result, first conjectured by Geroch, is proved to the extent, that the multipole moments of a static space-time characterize this space-time uniquely. As an offshoot of the proof one obtains an essentially coordinate-free algorithm for explicitly writing down a geometry in terms of it's moments in a purely algebraic manner. This algorithm seems suited for symbolic manipulation on a computer. (orig.)

  18. Knowledge space theory and union-closed sets conjecture

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available The knowledge space theory provides a framework for knowledge management. One of major problems is to find core information for a body of knowledge. Union closed set conjecture, if true, guarantees that for a given knowledge space, there is an information that is linked to at least half of the knowledge units. This paper deals with a variant problem, where the knowledge space is also a topological space and possibly infinite. We prove that there is a point belonging to as many open sets as of the topological space itself.

    Full Text Available In origins of life research, it is important to understand the difference between conjecture and hypothesis. This commentary explores the difference and recommends alternative hypotheses as a way to advance our understanding of how life can begin on the Earth and other habitable planets. As an example of how this approach can be used, two conditions have been proposed for sites conducive to the origin of life: hydrothermal vents in salty seawater, and fresh water hydrothermal fields associated with volcanic landmasses. These are considered as alternative hypotheses and the accumulating weight of evidence for each site is described and analyzed.

    An inflation of a graph G is obtained by replacing vertices in G by disjoint cliques and adding all possible edges between any pair of cliques corresponding to adjacent vertices in G. We prove that the chromatic number of an arbitrary inflation F of the Petersen graph is equal to the chromatic nu...... number of some inflated 5-cycle contained in F. As a corollary, we find that Hadwiger's Conjecture holds for any inflation of the Petersen graph. This solves a problem posed by Bjarne loft. (C) 2012 Elsevier B.V. All rights reserved....

    2016-01-01

    In this short note we clarify some aspects of the impact that the Weak Gravity Conjecture has on models of (generalized) natural inflation. We address in particular certain technical and conceptual concerns recently raised regarding the stringent constraints and conclusions found in our previous work http://dx.doi.org/10.1007/JHEP10(2015)023. We also point out the difficulties faced by attempts to evade these constraints. These new considerations improve the understanding of the quantum gravity constraints we found and further support the conclusion that it remains challenging for axions to drive natural inflation.

  3. Influence of reward preferences in attracting, retaining, and motivating knowledge workers in South African information technology companies

    Directory of Open Access Journals (Sweden)

    Mark Bussin

    2015-07-01

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

  4. A Conjectural Generating Function for Numbers of Curves on Surfaces

    Science.gov (United States)

    Göttsche, Lothar

    I give a conjectural generating function for the numbers of δ-nodal curves in a linear system of dimension δ on an algebraic surface. It reproduces the results of Vainsencher [V] for the case δ &\\le 6 and Kleiman-Piene [K-P] for the case δ &\\le 8. The numbers of curves are expressed in terms of five universal power series, three of which I give explicitly as quasimodular forms. This gives in particular the numbers of curves of arbitrary genus on a K3 surface and an abelian surface in terms of quasimodular forms, generalizing the formula of Yau-Zaslow for rational curves on K3 surfaces. The coefficients of the other two power series can be determined by comparing with the recursive formulas of Caporaso-Harris for the Severi degrees in 2. We verify the conjecture for genus 2 curves on an abelian surface. We also discuss a link of this problem with Hilbert schemes of points.

This has been illustrated by two examples. The first example was randomly chosen and the second example was designed to simulate the Collatz conjecture. Analysis of this TM based on the its IRR suggested new approaches that might be the basis for a proof of this conjecture. The method involves running the TM backwards from a configuration set (CS. This in general produces a tree of CSs at each step. The aim is to find CS's $\\mathtt{y}$ that are reachable from a CS $x$ that simply specifies the symbol about to be read and the machine state. This means that following the computation forward from $x$ by adding some symbols when needed at the pointer, the CS $y$ can be reached. These CS's form the basis of the LHS's of the IRR.

  6. Cosmic censorship conjecture in Kerr-Sen black hole

    Science.gov (United States)

    Gwak, Bogeun

    2017-06-01

    The validity of the cosmic censorship conjecture for the Kerr-Sen black hole, which is a solution to the low-energy effective field theory for four-dimensional heterotic string theory, is investigated using charged particle absorption. When the black hole absorbs the particle, the charge on it changes owing to the conserved quantities of the particle. Changes in the black hole are constrained to the equation for the motion of the particle and are consistent with the laws of thermodynamics. Particle absorption increases the mass of the Kerr-Sen black hole to more than that of the absorbed charges such as angular momentum and electric charge; hence, the black hole cannot be overcharged. In the near-extremal black hole, we observe a violation of the cosmic censorship conjecture for the angular momentum in the first order of expansion and the electric charge in the second order. However, considering an adiabatic process carrying the conserved quantities as those of the black hole, we prove the stability of the black hole horizon. Thus, we resolve the violation. This is consistent with the third law of thermodynamics.

  7. On the Anderson localization conjecture in Dusty Plasma

    Science.gov (United States)

    Liaw, Constanze; Busse, Kyle; Matthews, Lorin; Hyde, Truell

    2015-11-01

    In 1958, Anderson suggested that sufficiently large impurities in a semi-conductor could lead to spatial localization of electrons. This idea unfolded into the field of Anderson Localization, one of the most fascinating phenomena in solid-state physics as it plays a major role in the conductive properties of imperfectly ordered materials. The Anderson Localization Conjecture claims that random disorder of any strength causes localization of electrons in the medium. The problem has proven to be highly non-trivial. Over the years the community has argued whether spatial localization occurs in 2D for small impurities. From a mathematical standpoint, the conjecture is still considered an open question. In 2013, Liaw challenged the commonly held assumption that localization holds in 2D by introducing a new mathematically more rigorous method to test for extended states, and applying it to the discrete random Schrödinger operator. One of the advantages of the underlying method is its versatility. It can be applied to any ordered system such as colloids, crystals, and atomic lattices. In a cross-disciplinary effort we merge this method with a numerical code used to simulate 2D physics systems, in preparation for experimentally testing the theory against complex plasma crystals.

  14. Cosmic censorship conjecture in some matching spherical collapsing metrics

    Science.gov (United States)

    Lapiedra, Ramon; Morales-Lladosa, Juan Antonio

    2017-03-01

    A physically plausible Lemaître-Tolman-Bondi collapse in the marginally bound case is considered. By "physically plausible," we mean that the corresponding metric is C1 matched at the collapsing star surface and further that its intrinsic energy is, as due, stationary and finite. It is proved for this Lemaître-Tolman-Bondi collapse, for some parameter values, that its intrinsic central singularity is globally naked, thus violating the cosmic censorship conjecture with, for each direction, one photon, or perhaps a pencil of photons, leaving the singularity and reaching the null infinity. Our result is discussed in relation to some other cases in the current literature on the subject in which some of the central singularities are globally naked, too.

  16. Fate of the Hoop Conjecture in Quantum Gravity

    Science.gov (United States)

    Anzà, Fabio; Chirco, Goffredo

    2017-12-01

    We consider a closed region R of 3D quantum space described via SU(2) spin networks. Using the concentration of measure phenomenon we prove that, whenever the ratio between the boundary ∂R and the bulk edges of the graph overcomes a finite threshold, the state of the boundary is always thermal, with an entropy proportional to its area. The emergence of a thermal state of the boundary can be traced back to a large amount of entanglement between boundary and bulk degrees of freedom. Using the dual geometric interpretation provided by loop quantum gravity, we interpret such phenomenon as a pregeometric analogue of Thorne's "hoop conjecture," at the core of the formation of a horizon in general relativity.

  17. A Comment on Quantum Distribution Functions and the OSV Conjecture

    CERN Document Server

    Gómez, C; Gomez, Cesar; Montanez, Sergio

    2006-01-01

    Using the attractor mechanism and the relation between the quantization of $H^{3}(M)$ and topological strings on a Calabi Yau threefold $M$ we define a map from BPS black holes into coherent states. This map allows us to represent the Bekenstein-Hawking-Wald entropy as a quantum distribution function on the phase space $H^{3}(M)$. This distribution function is a mixed Husimi/anti-Husimi distribution corresponding to the different normal ordering prescriptions for the string coupling and deviations of the complex structure moduli. From the integral representation of this distribution function in terms of the Wigner distribution we recover the Ooguri-Strominger-Vafa (OSV) conjecture in the region "at infinity" of the complex structure moduli space. The physical meaning of the OSV corrections are briefly discussed in this limit.

  18. Cognition and Language: From Apprehension to Judgment -- Quantum Conjectures

    Science.gov (United States)

    Arecchi, F. T.

    2014-12-01

    We critically discuss the two moments of human cognition, namely, apprehension (A), whereby a coherent perception emerges from the recruitment of neuronal groups, and judgment (B), that entails the comparison of two apprehensions acquired at different times, coded in a suitable language and recalled by memory. (B) requires selfconsciousness, in so far as the agent who expresses the judgment must be aware that the two apprehensions are submitted to his/her own scrutiny and that it is his/her duty to extract a mutual relation. Since (B) lasts around 3 seconds, the semantic value of the pieces under comparison must be decided within this time. This implies a fast search of the memory contents. As a fact, exploring human subjects with sequences of simple words, we find evidence of a limited time window, corresponding to the memory retrieval of a linguistic item in order to match it with the next one in a text flow (be it literary, or musical,or figurative). Classifying the information content of spike trains, an uncertainty relation emerges between the bit size of a word and its duration. This uncertainty is ruled by a constant that can be given a numerical value and that has nothing to do with Planck's constant. A "quantum conjecture" in the above sense might explain the onset and decay of the memory window connecting successive pieces of a linguistic text. The conjecture here formulated is applicable to other reported evidences of quantum effects in human cognitive processes, so far lacking a plausible framework since no efforts to assign a quantum constant have been associated.

  2. HILBERT-PÓLYA Conjecture, Zeta Functions and Bosonic Quantum Field Theories

    Science.gov (United States)

    Andrade, Julio C.

    2013-07-01

    The original Hilbert and Pólya conjecture is the assertion that the nontrivial zeros of the Riemann zeta function can be the spectrum of a self-adjoint operator. So far no such operator was found. However, the suggestion of Hilbert and Pólya, in the context of spectral theory, can be extended to approach other problems and so it is natural to ask if there is a quantum mechanical system related to other sequences of numbers which are originated and motivated by Number Theory. In this paper, we show that the functional integrals associated with a hypothetical class of physical systems described by self-adjoint operators associated with bosonic fields whose spectra is given by three different sequence of numbers cannot be constructed. The common feature of the sequence of numbers considered here, which causes the impossibility of zeta regularizations, is that the various Dirichlet series attached to such sequences — such as those which are sums over "primes" of (norm P)-s have a natural boundary, i.e. they cannot be continued beyond the line Re(s) = 0. The main argument is that once the regularized determinant of a Laplacian is meromorphic in s, it follows that the series considered above cannot be a regularized determinant. In other words, we show that the generating functional of connected Schwinger functions of the associated quantum field theories cannot be constructed.

    We examine the effectiveness of the weak gravity conjecture in constraining the dark energy by comparing with observations. For general dark energy models with plausible phenomenological interactions between dark sectors, we find that although the weak gravity conjecture can constrain the dark energy, the constraint is looser than that from the observations.

  8. Existence and uniqueness of consistent conjectural variation equilibrium in electricity markets

    International Nuclear Information System (INIS)

    Liu, Youfei; Cai, Bin; Ni, Y.X.; Wu, Felix F.

    2007-01-01

    The game-theory based methods are widely applied to analyze the market equilibrium and to study the strategic behavior in the oligopolistic electricity markets. Recently, the conjecture variation approach, one of well-studied methods in game theory, is reported to model the strategic behavior in deregulated electricity markets. Unfortunately, the conjecture variation models have been criticized for the drawback of logical inconsistence and possibility of abundant equilibria. Aiming for this, this paper investigates the existence and uniqueness of consistent conjectural variation equilibrium in electricity markets. With several good characteristics of the electricity market and with an infinite horizon optimization model, it is shown that the consistent conjecture variation will satisfy a set of coupled nonlinear equations and there will be only one equilibrium. This result can provide the fundamentals for further applications of the conjecture variation approach. (author)

  9. Learning for supplying as a motive to be the early adopter of a new energy technology: A study on the adoption of stationary fuel cells

    International Nuclear Information System (INIS)

    Huang, A.Y.-J.; Liu, R.-H.

    2008-01-01

    By early adopting a new technology, firms may attempt to improve their production efficiency and become further involved in the supply chain of the technology. These two different advantages derived from learning a new technology are identified as motives for adopting the technology. When learning for supplying (LFS) (becoming involved in the supply chain of the new technology) highlighted in this paper is significant enough, potential adopters may still be willing to adopt the new technology, even though learning for using (LFU) (increasing current production efficiency) is not significant. This paper identifies LFS as a motive for early adopters of the new technology. Firms may adopt a new technology for the purpose of learning how to become the suppliers of the relevant parts, materials, or equipment for the new technology. By investigating the adoption decision of a new energy technology (namely, phosphoric acid fuel cells (PAFC)), our arguments are supported by both observation of early adopters' attributes and a survey of Taiwanese firms' willingness to adopt new technology

  11. Global energy issues affecting aeronautics: a reasoned conjecture

    Science.gov (United States)

    Allen, John E.

    1999-07-01

    This paper is a reasoned conjecture of the future up to 2050 AD including estimates of energy supply and consumption, transport system developments and corresponding pollution effects. Results of the logistic substitution methods (Volterra-Lotka) are used in forecasting trends in innovation, transport and energy. Later work on normative forecasts is also included. The future of aeronautics cannot be isolated from events in other transport modes which together create the major problem of crude oil replacement during the next century. Natural gas will be the dominant energy source for the next 80 years and a major question is how best to use it for aviation. The work on which this paper is based was started in 1992 to answer the following questions: Is the future oil shortfall sufficient to restrict aviation traffic and growth in the next 50 years? If so, what is its substitute? Can a substitute be obtained cheaply enough to free aviation from future kerosine shortages? Is it paramount to change to liquid hydrogen fuel to avoid future fuel shortage in aeronautics, incidentally conferring possible environmental advantages? There was no adequate evidence available to answer these questions, hence a method was devised to bring together several sets of partial data that contributed to the solution. The essence is to use the mean annual growth rate of traffic or energy over a future period as a pseudo-independent variable. This allows the inclusion of alternative high and low estimates of all the important quantities involved.

  12. Does gravity induce wavefunction collapse? An examination of Penrose's conjecture

    Science.gov (United States)

    Gao, Shan

    2013-05-01

    According to Penrose, the fundamental conflict between the superposition principle of quantum mechanics and the principle of general covariance of general relativity entails the existence of wavefunction collapse, e.g. a quantum superposition of two different space-time geometries will collapse to one of them due to the ill-definedness of the time-translation operator for the superposition. In this paper, we argue that Penrose's conjecture on gravity's role in wavefunction collapse is debatable. First of all, it is still a controversial issue what the exact nature of the conflict is and how to resolve it. Secondly, Penrose's argument by analogy is too weak to establish a necessary connection between wavefunction collapse and the conflict as understood by him. Thirdly, the conflict does not necessarily lead to wavefunction collapse. The reason is that the conflict or the problem of ill-definedness for a superposition of different space-time geometries also needs to be solved before the collapse of the superposition finishes, and once the conflict has been resolved, the wavefunction collapse will lose its physical basis relating to the conflict. In addition, we argue that Penrose's suggestions for the collapse time formula and the preferred basis are also problematic.

  13. Planck scale physics and Newton's ultimate object conjecture

    International Nuclear Information System (INIS)

    Winterberg, F.

    1996-01-01

    According to Newton, the ultimate building blocks of matter are hard frictionless spheres. This conjecture is here analyzed under different assumptions, which are: 1. The ultimate objects of matter are frictionless positive and negative Planck mass particles obeying nonrelativistic Newtonian mechanics. 2. The Planck mass particles interact with the Planck force c 4 G (c velocity of light, G Newton's constant) locally within a Planck length r p , with the positive Planck mass particles exerting a repulsive and the negative Planck mass particles an attractive force, whereby particles of equal sign are accelerated away from each other and those of opposite sign - as a particle-hole interaction - accelerated towards each other. 3. Space if filled with an equal number of positive and negative Planck mass particles, whereby each Planck length volume r p 3 occupies one Planck mass particle. Making these three assumptions we derive: 1. Nonrelativistic quantum mechanics as an approximation with departures from this approximation suppressed by the Planck length. 2. Lorentz invariance as a dynamic symmetry for energies small compared to the Planck energy. 3. The operator field equation for the previously proposed Planck either model of an unified theory of elementary particles. In contrast to theories in which the ultimate objects are strings at the Planck scale, the alternative theory proposed here does not need a higher dimensional space, but rather can be formulated in 3+1 dimensions.

    2011-01-18

    Through discussion the conference aims to: (1) Identify core components of a comprehensive global biosurveillance capability; (2) Determine the scientific and technical bases to support such a program; (3) Explore the improvement in biosurveillance to enhance regional and global disease outbreak prediction; (4) Recommend an engagement approach to establishing an effective international community and regional or global network; (5) Propose implementation strategies and the measures of effectiveness; and (6) Identify the challenges that must be overcome in the next 3-5 years in order to establish an initial global biosurveillance capability that will have significant positive impact on BioNP as well as public health and/or agriculture. There is also a look back at the First Biothreat Nonproliferation Conference from December 2007. Whereas the first conference was an opportunity for problem solving to enhance and identify new paradigms for biothreat nonproliferation, this conference is moving towards integrated comprehensive global biosurveillance. Main reasons for global biosurveillance are: (1) Rapid assessment of unusual disease outbreak; (2) Early warning of emerging, re-emerging and engineered biothreat enabling reduced morbidity and mortality; (3) Enhanced crop and livestock management; (4) Increase understanding of host-pathogen interactions and epidemiology; (5) Enhanced international transparency for infectious disease research supporting BWC goals; and (6) Greater sharing of technology and knowledge to improve global health.

  18. Analytical study of the conjecture rule for the combination of multipole effects in LHC

    CERN Document Server

    Guignard, Gilbert

    1997-01-01

    This paper summarizes the analytical investigation done on the conjecture law found by tracking for the effect on the dynamic aperture of the combination of two multipoles of various order. A one-dimensional model leading to an integrable system has been used to find closed formulae for the dynamic aperture associated with a fully distributed multipole. The combination has then been studied and the resulting expression compared with the assumed conjecture law. For integrated multipoles small with respect to the focusing strength, the conjecture appears to hold, though with an exponent different from the one expected by crude reasoning.

  19. Note on a reformulation of the strong cosmic censor conjecture based on computability

    2002-12-01

    In this Letter we provide a reformulation of the strong cosmic censor conjecture taking into account recent results on Malament-Hogarth space-times. We claim that the strong version of the cosmic censor conjecture can be formulated by postulating that a physically reasonable space-time is either globally hyperbolic or possesses the Malament-Hogarth property. But it is known that a Malament-Hogarth space-time in principle is capable for performing non-Turing computations such as checking consistency of ZFC set theory. In this way we get an intimate conjectured link between the cosmic censorship scenario and computability theory.

    We consider time-dependent solutions of the Einstein-Maxwell equations using anti-de Sitter (AdS) boundary conditions, and provide the first counterexample to the weak cosmic censorship conjecture in four spacetime dimensions. Our counterexample is entirely formulated in the Poincaré patch of AdS. We claim that our results have important consequences for quantum gravity, most notably to the weak gravity conjecture.

    2003-01-01

    In this paper we examine the cosmic no-hair conjecture (CNHC) in braneworld scenarios. For the validity of this conjecture, in addition to the strong- and weak-energy conditions for the matter field, a similar type of assumption is made on the quadratic correction term and there is a restriction on the non-local term. It is shown using examples with realistic fluid models that strong- and weak-energy conditions are sufficient for the CNHC in braneworld scenarios.

    1984-01-01

    Some possible directions for the future evolution of the mirror approach to fusion are outlined, in the context of economically-motivated criteria. Speculations are given as to the potential advantages, economic and otherwise, of the use of axially-symmetric systems, operated in semi-collisional regimes of lower Q (fusion power balance ratio) than that projected for present-day tandem mirror designs. These regims include barely tandem modes, and ion-heated modes, in association with higher efficiency direct conversion. Another possible economically advantageous approach mentioned is the use of a tandem mirror plasma to stabilize a FRM (field-reversed mirror) plasma, with potential synergistic advantages

    Full Text Available Access to training opportunities is strongly correlated with health workers’ motivation because it enables health workers to take on more challenging duties. Mobile technology can be leveraged for professional development support by providing access to open education resources. Community Health Nurses (CHNs in Ghana are the frontline health workers of the Ghana Health Service (GHS and play a vital role in extending maternal and child health care to rural communities. However, as the lowest credentialed nurses, they are at the bottom of the GHS hierarchy. CHNs have limited opportunities for career advancement and report challenges with isolation and lack of resources. Leveraging open-source technology platforms and open eLearning content, the Care Community Hub (CCH project sought to address these barriers in CHN motivation by developing and deploying a mobile application (app, CHN on the Go, to CHNs in five rural districts. The app supports CHNs through tools for continuous learning, diagnostic decision-making, and improved nurse-supervisor interactions. This paper focuses on the adaptation and use of the open eLearning content to address CHNs’ motivation challenges and, ultimately, improve their knowledge and job performance as a result of having access to open education resources.

The experimental estimates of conjectural variation elasticities were obtained based on price elasticity of demand, cost elasticity and marginal cost elasticity for the selected industries. In this research demand function AIDS was used to obtain the price elasticity. The AIDS function was estimated using SUR and the demand price elasticity is calculated by calfent. The results show that "Vegetable oils and animal" industry with 19.37 have the most conjectural variation elasticity among the selected industries (The more divergent the conjectural variation elasticity is from zero the more likely the monopoly exists. In addition, dairy, sugar and malt industries have the most conjectural variation elasticity with 18.01, 17.18, and 10.51 respectively.

    Full Text Available The Mishchenko-Fomenko conjecture says that for each real or complex finite-dimensional Lie algebra g there exists a complete set of commuting polynomials on its dual space g*. In terms of the theory of integrable Hamiltonian systems this means that the dual space g* endowed with the standard Lie-Poisson bracket admits polynomial integrable Hamiltonian systems. This conjecture was proved by S. T. Sadetov in 2003. Following his idea, we give an explicit geometric construction for commuting polynomials on g* and consider some examples.

  11. Wormholes, emergent gauge fields, and the weak gravity conjecture

    Energy Technology Data Exchange (ETDEWEB)

    Harlow, Daniel [Center for the Fundamental Laws of Nature, Physics Department, Harvard University,Cambridge MA, 02138 (United States)

    2016-01-20

    This paper revisits the question of reconstructing bulk gauge fields as boundary operators in AdS/CFT. In the presence of the wormhole dual to the thermofield double state of two CFTs, the existence of bulk gauge fields is in some tension with the microscopic tensor factorization of the Hilbert space. I explain how this tension can be resolved by splitting the gauge field into charged constituents, and I argue that this leads to a new argument for the “principle of completeness”, which states that the charge lattice of a gauge theory coupled to gravity must be fully populated. I also claim that it leads to a new motivation for (and a clarification of) the “weak gravity conjecture”, which I interpret as a strengthening of this principle. This setup gives a simple example of a situation where describing low-energy bulk physics in CFT language requires knowledge of high-energy bulk physics. This contradicts to some extent the notion of “effective conformal field theory”, but in fact is an expected feature of the resolution of the black hole information problem. An analogous factorization issue exists also for the gravitational field, and I comment on several of its implications for reconstructing black hole interiors and the emergence of spacetime more generally.

  12. Doran-Harder-Thompson Conjecture via SYZ Mirror Symmetry: Elliptic Curves

    Science.gov (United States)

    Kanazawa, Atsushi

    2017-04-01

    We prove the Doran-Harder-Thompson conjecture in the case of elliptic curves by using ideas from SYZ mirror symmetry. The conjecture claims that when a Calabi-Yau manifold X degenerates to a union of two quasi-Fano manifolds (Tyurin degeneration), a mirror Calabi-Yau manifold of X can be constructed by gluing the two mirror Landau-Ginzburg models of the quasi-Fano manifolds. The two crucial ideas in our proof are to obtain a complex structure by gluing the underlying affine manifolds and to construct the theta functions from the Landau-Ginzburg superpotentials.

    We discuss the Nakamura's conjecture stating that the Tomimatsu-Sato black hole solution with an integer deformation parameter n is composed of the special solutions of the Toda molecule equation at the nth lattice site. From the previous work, in which the conjecture was partly analytically proved, we go further towards the final full proof by rearranging the rotation parameter. The proof is explicitly performed for the highest and lowest orders. Though the proof for all orders still remains unsolved, the prospect to the full proof becomes transparent and workable by our method. (paper)

    This study aims to explore the extent to which the use of analogy reasoning when students conduct conjecture in developing the scientific approach, so that the knowledge of the students can be used to build new knowledge. Analysis was conducted on student learning outcomes in Ciamis district. Based on these results, it was found the teacher not give an opportunity to the students to make conjecture on the students in problem solving as well as the construction of new knowledge. Moreover, teachers do not take advantage of analogical reasoning and scientific approach in constructing new knowledge.

    For an algebraic number field K that is a finite 2-extension of the CM-field k with trivial Iwasawa invariant {mu}{sub 2}(k), we prove that its cyclotomic Z{sub l}-extension K{sub {infinity}/}K satisfies the feeble conjecture on the 2-adic regulator. In particular, this conjecture holds for K{sub {infinity}/}K if K is a 2-extension of a field k that is Abelian over Q. We also obtain other results in the same direction.

    We study the dimensional asymptotics of the effective actions, or functional determinants, for the Dirac operator D and Laplacians on round S n . For Laplacians the behavior depends on “the coupling strength” β, and one cannot in general expect a finite limit of , and for the ordinary Laplacian......, , we prove it to be , for odd dimensions. For the Dirac operator, Bär and Schopka conjectured a limit of unity for the determinant (Bär and Schopka, Geometric Analysis and Nonlinear PDEs, pp. 39–67, 2003), i.e. We prove their conjecture rigorously, giving asymptotics, as well as a pattern...

  19. Principia designae pre-design, design, and post-design : social motive for the highly advanced technological society

    CERN Document Server

    2015-01-01

    This book presents a broad design purview within the framework of “pre-design, design, and post-design” by focusing on the “motive of design,” which implies an underlying reason for the design of a product. The chapters are comprised of papers based on discussions at the “Design Research Leading Workshop” held in Nara, Japan, in 2013. This book encourages readers to enhance and expand their thinking within a widened design perspective.

  20. THE INFLUENCE OF SCHOOL MANAGEMENT IN THE MOTIVATION OF THE TEACHERS OF THE FEDERAL INSTITUTE OF EDUCATION, SCIENCE AND TECHNOLOGY OF ESPÍRITO SANTO-BRASIL

    2017-08-01

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

    2017-12-01

    Investigation at Southern Okinawa Trough, western Kume Island, and Tokara Islands was performed from June 26 to July 12, 2016, as a part of Japan's cross ministerial Strategic Innovation Promotion Program (SIP) for a complete understanding of active hydrothermal vents. In this investigation, water column sonar data was obtained using multi-beam sonar (EM122) onboard YOKOSUKA (Japan Agency for Marine-Earth Science and Technology) and methane plumes were alsp monitored (YK16-07). Multi-beam sonar is an acoustic instrument used to measure submarine topography, and in this investigation, plumes were observed to successfully regenerate the data. It also became clear that volume backscattering strength (SV) of plumes varies, depending on the area where they are settled. On the other hand, components of plumes are still unknown. In this study, acoustic data obtained from YK16-07 will be reviewed using analytical software (echo view 7) to calculate volume backscattering strength (SV) of plumes. Likewise, multi-beam sonar (EM122) onboard DAIICHI KAIYOMARU (KAIYO ENGINEERING CO., LTD) was used to collect acoustic data. This already known data of methane plume from Sea of Japan will be analyzed using echo view 7. By comparing these data, plume components will be examined from plume size.

    International Nuclear Information System (INIS)

    Gill, Tepper L.; Zachary, W.W.

    2002-01-01

    In this paper, we provide a representation theory for the Feynman operator calculus. This allows us to solve the general initial-value problem and construct the Dyson series. We show that the series is asymptotic, thus proving Dyson's second conjecture for quantum electrodynamics. In addition, we show that the expansion may be considered exact to any finite order by producing the remainder term. This implies that every nonperturbative solution has a perturbative expansion. Using a physical analysis of information from experiment versus that implied by our models, we reformulate our theory as a sum over paths. This allows us to relate our theory to Feynman's path integral, and to prove Dyson's first conjecture that the divergences are in part due to a violation of Heisenberg's uncertainly relations

    2010-02-21

    We numerically investigated the sequences of initial data of a thin spindle and a thin ring in five-dimensional space-time in the context of the cosmic censorship conjecture. We modeled the matter in non-rotating homogeneous spheroidal or toroidal configurations under the momentarily static assumption, solved the Hamiltonian constraint equation and searched the apparent horizons. We discussed when S{sup 3} (black-hole) or S{sup 1} x S{sup 2} (black-ring) horizons ('black objects') are formed. By monitoring the location of the maximum Kretchmann invariant, an appearance of 'naked singularity' or 'naked ring' under special situations is suggested. We also discuss the validity of the hyper-hoop conjecture using a minimum area around the object, and show that the appearance of the ring horizon does not match with this hoop.

    2013-03-01

    Full Text Available We investigate the classical Zassenhaus Conjecture (ZC for integral group rings of alternating groups A9 and A10. Even the question (ZC remains open as no counterexample is known up to date, it been confirmed for special types of groups such as nilpotent groups by Roggenkamp, Scot and Weiss. However, a new method based on the partial augmentation of torsion units been established by Luthar and Passi to confirm the (ZC for A5. Later a weaker version of (ZC was proposed in 2007, we call it the Prime Graph Conjecture (PGC about the Gruenberg-Kegel (prime graph of the group of all normalized units of the integral group ring of a finite group. Recently, the (PGC has a positive answer for solvable groups, Frobenius groups and several simple groups. Here, as a consequence of our results, we confirm the (PGC for integral group rings of alternating groups An for all n<11.

    2017-12-01

    The purpose of this study is to reveal the development of knowledge of ordinary students to be like gifted students in the classroom based on Piaget's theory. In exposing it, students are given an open problem of classical analogy. Researchers explore students who conjecture via analogical reasoning in problem solving. Of the 32 students, through the method of think out loud and the interview was completed: 25 students conjecture via analogical reasoning. Of the 25 students, all of them have almost the same character in problem solving/knowledge construction. For that, a student is taken to analyze the thinking process while solving the problem/construction of knowledge based on Piaget's theory. Based on Piaget's theory in the development of the same knowledge, gifted students and ordinary students have similar structures in final equilibrium. They begin processing: assimilation and accommodation of problem, strategies, and relationships.

  19. Motivated explanation

    2015-01-01

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

    We model a shock wave in an ideal gas by combining the Burnett approximation and Holian's conjecture. We use the temperature in the direction of shock propagation rather than the average temperature in the Burnett transport coefficients. The shock wave profiles and shock thickness are compared with other theories. The results are found to agree better with the nonequilibrium molecular dynamics (NEMD) and direct simulation Monte Carlo (DSMC) data than the Burnett equations and the modified Navier-Stokes theory.

  3. More about Birkhoff's invariant and Thorne's hoop conjecture for horizons

    2011-10-07

    A recent precise formulation of the hoop conjecture in four spacetime dimensions is that the Birkhoff invariant {beta} (the least maximal length of any sweepout or foliation by circles) of an apparent horizon of energy E and area A should satisfy {beta} {<=} 4{pi}E. This conjecture together with the cosmic censorship or isoperimetric inequality implies that the length l of the shortest non-trivial closed geodesic satisfies l{sup 2} {<=} {pi}A. We have tested these conjectures on the horizons of all four-charged rotating black hole solutions of ungauged supergravity theories and found that they always hold. They continue to hold in the presence of a negative cosmological constant, and for multi-charged rotating solutions in gauged supergravity. Surprisingly, they also hold for the Ernst-Wild static black holes immersed in a magnetic field, which are asymptotic to the Melvin solution. In five spacetime dimensions we define {beta} as the least maximal area of all sweepouts of the horizon by two-dimensional tori, and find in all cases examined that {beta} (g) {<=} {l_brace}16 {pi}/ 3{r_brace} E, which we conjecture holds quiet generally for apparent horizons. In even spacetime dimensions D = 2N + 2, we find that for sweepouts by the product S{sup 1} x S{sup D-4}, {beta} is bounded from above by a certain dimension-dependent multiple of the energy E. We also find that l{sup D-2} is bounded from above by a certain dimension-dependent multiple of the horizon area A. Finally, we show that l{sup D-3} is bounded from above by a certain dimension-dependent multiple of the energy, for all Kerr-AdS black holes.

    In this paper we give sufficient conditions on a sequence of multipole moments for a static spacetime to exist with precisely these moments. The proof is constructive in the sense that a metric having prescribed multipole moments up to a given order can be calculated. Since these sufficient conditions agree with already known necessary conditions, this completes the proof of a long standing conjecture due to Geroch.

    The purpose of the article is to provide partial proofs for two conjectures given by Witte and Forrester in "Moments of the Gaussian β Ensembles and the large N expansion of the densities" ([1]) with the use of the topological recursion adapted for general β Gaussian case. In particular, the paper uses a version at coinciding points that provides a simple proof for some of the coefficients involved in the conjecture. Additionally, we propose a generalized version of the conjectures for all correlation functions evaluated at coinciding points.

  12. Agency context and tailored training in technology transfer: A pilot evaluation of motivational interviewing training for community counselors

    2009-01-01

    Few empirical studies are available to guide best practices for transferring evidenced-based treatments to community substance abuse providers. To maximize the learning and maintenance of new clinical skills, this study tested a context-tailored training model (CTT) which used standardized patient actors in role-plays tailored to agency clinical context, repetitive cycles of practice and feedback, and enhanced organizational support. This study reports the results of a randomized pilot evaluation of CTT for motivational interviewing (MI). Investigators randomly assigned community substance abuse treatment agencies to receive either CTT or a standard two-day MI workshop. The study also evaluated the effects of counselor-level and organizational-level variables on the learning of MI. No between-condition differences were observed on the acquisition and maintenance of MI skills, despite reported higher satisfaction with the more costly context tailored model. Analyses revealed that those counselors with more formal education and less endorsement of a disease model of addiction made the greatest gains in MI skills, irrespective of training condition. Similarly, agencies whose individual counselors viewed their organization as being more open to change and less supportive of autonomy showed greater average staff gains in MI skills, again, irrespective of training method. Post-training activities within agencies that supported the ongoing learning and implementation of MI mediated the effects of organizational openness to change. This pilot study suggests that tailored training methods may not produce better outcomes than traditional workshops for the acquisition of evidence-based practice and that efforts to enhance dissemination should be focused on characteristics of learners and ongoing organizational support of learning.

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

    Using the Educational Longitudinal Study of 2002/06, this study examined the effects of the selected mathematical learning and teacher motivation factors on graduates' science, technology, engineering, and math (STEM) related major choices in 4-year colleges and universities, as mediated by math performance and math self-efficacy. Using multilevel structural equation modeling, I analyzed: (1) the association between mathematical learning instruction factors (i.e., computer, individual, and lecture-based learning activities in mathematics) and students' STEM major choices in 4-year colleges and universities as mediated by math performance and math self-efficacy and (2) the association between school factor, teacher motivation and students' STEM major choices in 4-year colleges and universities via mediators of math performance and math self-efficacy. The results revealed that among the selected learning experience factors, computer-based learning activities in math classrooms yielded the most positive effects on math self-efficacy, which significantly predicted the increase in the proportion of students' STEM major choice as mediated by math self-efficacy. Further, when controlling for base-year math Item Response Theory (IRT) scores, a positive relationship between individual-based learning activities in math classrooms and the first follow-up math IRT scores emerged, which related to the high proportion of students' STEM major choices. The results also indicated that individual and lecture-based learning activities in math yielded positive effects on math self-efficacy, which related to STEM major choice. Concerning between-school levels, teacher motivation yielded positive effects on the first follow up math IRT score, when controlling for base year IRT score. The results from this study inform educators, parents, and policy makers on how mathematics instruction can improve student math performance and encourage more students to prepare for STEM careers.

  1. End Point of Black Ring Instabilities and the Weak Cosmic Censorship Conjecture.

    We produce the first concrete evidence that violation of the weak cosmic censorship conjecture can occur in asymptotically flat spaces of five dimensions by numerically evolving perturbed black rings. For certain thin rings, we identify a new, elastic-type instability dominating the evolution, causing the system to settle to a spherical black hole. However, for sufficiently thin rings the Gregory-Laflamme mode is dominant, and the instability unfolds similarly to that of black strings, where the horizon develops a structure of bulges connected by necks which become ever thinner over time.

    2016-01-01

    Full Text Available The energy and momentum of some diagonal anisotropic Bianchi type Universes are obtained using different energy-momentum complexes in the framework of General Relativity. The Møller energy is found to be zero for all the Universes considered in the present work. In all other prescriptions, the energy and momentum vanish when the sum of the metric parameters α and β vanishes. This result obviously raises a question: why this specific choice? We have explored Tryon’s conjecture that the Universe must have a zero net value for all conserved quantities to get some ideas on this issue.

    We prove that if $M$ is a maximal $k$-edge-colorable subgraph of a multigraph $G$ and if $F = \\{v \\in V(G) : d_M(v) \\leq k-\\mu(v)\\}$, then $d_F(v) \\leq d_M(v)$ for all $v \\in F$. (When $G$ is a simple graph, the set $F$ is just the set of vertices having degree less than $k$ in $M$.) This implies Vizing's Theorem as well as a special case of Tuza's Conjecture on packing and covering of triangles. A more detailed version of our result also implies Vizing's Adjacency Lemma for simple graphs.

    Let R denote the reals, and let h: R^n --> R be a continuous, piecewise-polynomial function. The Pierce-Birkhoff conjecture (1956) is that any such h is representable in the form sup_i inf_j f_{ij}, for some finite collection of polynomials f_{ij} in R[x_1,...,x_n]. (A simple example is h(x_1) = |x_1| = sup{x_1, -x_1}.) In 1984, L. Mahe and, independently, G. Efroymson, proved this for n 2. In this paper we prove an analogous result for "generalized polynomials" (...

  9. Motivating pharmacists.

    Donehew, G R

    1979-01-01

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

    If F is a (possibly infinite) subset of an abelian group Γ, then we define f(F,Γ) as the smallest natural number such that every f(F,Γ)-edge-connected (finite) graph G has a flow where all flow values are elements in F. We prove that f(F,Γ) exists if and only if some odd sum of elements in F equals...... some even sum. We discuss various instances of this problem. We prove that every 6-edge-connected graph has a flow whose flow values are the three roots of unity in the complex plane.

We prove...... that every 14-edge-connected graph has a flow whose flow values are the five roots of unity in the complex plane. Any such flow is balanced modulo 5. So, if the edge-connectivity 14 can be reduced to 9, then the 5-flow conjecture follows, as observed by F. Jaeger. We use vector flow to prove that, for each...

  13. Strategic Generation with Conjectured Transmission Price Responses in a Mixed Transmission Pricing System. Part 1. Formulation

    International Nuclear Information System (INIS)

    Hobbs, B.F.; Rijkers, F.A.M.

    2004-05-01

    The conjectured supply function (CSF) model calculates an oligopolistic equilibrium among competing generating companies (GenCos), presuming that GenCos anticipate that rival firms will react to price increases by expanding their sales at an assumed rate. The CSF model is generalized here to include each generator's conjectures concerning how the price of transmission services (point-to-point service and constrained interfaces) will be affected by the amount of those services that the generator demands. This generalization reflects the market reality that large producers will anticipate that they can favorably affect transmission prices by their actions. The model simulates oligopolistic competition among generators while simultaneously representing a mixed transmission pricing system. This mixed system includes fixed transmission tariffs, congestion-based pricing of physical transmission constraints (represented as a linearized dc load flow), and auctions of interface capacity in a path-based pricing system. Pricing inefficiencies, such as export fees and no credit for counterflows, can be simulated. The model is formulated as a linear mixed complementarity problem, which enables very large market models to be solved. In the second paper of this two-paper series, the capabilities of the model are illustrated with an application to northwest Europe, where transmission pricing is based on such a mixture of approaches

  14. Testing the ortholog conjecture with comparative functional genomic data from mammals.

    Directory of Open Access Journals (Sweden)

    Nathan L Nehrt

    2011-06-01

    Full Text Available A common assumption in comparative genomics is that orthologous genes share greater functional similarity than do paralogous genes (the "ortholog conjecture". Many methods used to computationally predict protein function are based on this assumption, even though it is largely untested. Here we present the first large-scale test of the ortholog conjecture using comparative functional genomic data from human and mouse. We use the experimentally derived functions of more than 8,900 genes, as well as an independent microarray dataset, to directly assess our ability to predict function using both orthologs and paralogs. Both datasets show that paralogs are often a much better predictor of function than are orthologs, even at lower sequence identities. Among paralogs, those found within the same species are consistently more functionally similar than those found in a different species. We also find that paralogous pairs residing on the same chromosome are more functionally similar than those on different chromosomes, perhaps due to higher levels of interlocus gene conversion between these pairs. In addition to offering implications for the computational prediction of protein function, our results shed light on the relationship between sequence divergence and functional divergence. We conclude that the most important factor in the evolution of function is not amino acid sequence, but rather the cellular context in which proteins act.

    2017-06-01

    In this paper, we provide a counter-example to the ER=EPR conjecture. In an anti-de Sitter space, we construct a pair of maximally entangled but separated black holes. Due to the vacuum decay of the anti-de Sitter background toward a deeper vacuum, these two parts can be trapped by bubbles. If these bubbles are reasonably large, then within the scrambling time, there should appear an Einstein-Rosen bridge between the two black holes. Now by tracing more details on the bubble dynamics, one can identify parameters such that one of the two bubbles either monotonically shrinks or expands. Because of the change of vacuum energy, one side of the black hole would evaporate completely. Due to the shrinking of the apparent horizon, a signal of one side of the Einstein-Rosen bridge can be viewed from the opposite side. We analytically and numerically demonstrate that within a reasonable semi-classical parameter regime, such process can happen. Bubbles are a non-perturbative effect, which is the crucial reason that allows the transmission of information between the two black holes through the Einstein-Rosen bridge, even though the probability is highly suppressed. Therefore, the ER=EPR conjecture cannot be generic in its present form and its validity maybe restricted.

  16. The positive action conjecture and asymptotically euclidean metrics in quantum gravity

    Gibbons, G.W.; Pope, C.N.

    1979-01-01

    The positive action conjecture requires that the action of any asymptotically Euclidean 4-dimensional Riemannian metric be positive, vanishing if and only if the space is flat. Because any Ricci flat, asymptotically Euclidean metric has zero action and is local extremum of the action which is a local minimum at flat space, the conjecture requires that there are no Ricci flat asymptotically Euclidean metrics other than flat space, which would establish that flat space is the only local minimum. We prove this for metrics on R 4 and a large class of more complicated topologies and for self-dual metrics. We show that if Rsupμsubμ >= 0 there are no bound states of the Dirac equation and discuss the relevance to possible baryon non-conserving processes mediated by gravitational instantons. We conclude that these are forbidden in the lowest stationary phase approximation. We give a detailed discussion of instantons invariant under an SU(2) or SO(3) isometry group. We find all regular solutions, none of which is asymptotically Euclidean and all of which possess a further Killing vector. In an appendix we construct an approximate self-dual metric on K3 - the only simply connected compact manifold which admits a self-dual metric. (orig.) [de

    In HIV-infected individuals, non-injection drug use (NIDU) compromises many health outcomes. In HIV primary care, the efficacy of brief motivational interviewing (MI) to reduce NIDU is unknown, and drug users may need greater intervention. We designed an enhancement to MI, HealthCall (HC), for daily patient self-monitoring calls to an interactive voice response (IVR) phone system, and provided participants with periodic personalized feedback. To reduce NIDU among HIV primary care patients, we compared the efficacy of MI+HealthCall to MI-only and an educational control condition. Participants age >18 with >4days of NIDU during the prior 30days were recruited from large urban HIV primary care clinics. Of the 240 participants, 83 were randomly assigned to control, 77 to MI-only, and 80 to MI+HC. Counselors provided educational control, MI-only or MI+HC at baseline. At 30 and 60days (end-of-treatment), counselors briefly discussed drug use, moods and health behaviors, using HealthCall-generated graphs with MI+HC patients. Primary outcomes (last 30days) were number of days used primary drug (NumDU), and total quantity of primary drug used (dollar amount spent; QuantU), derived from the Time-Line Follow-Back. Across all groups, at end-of-treatment, frequency and quantity of NIDU decreased, with significantly greater reductions in the MI-Only group. A twelve-month post-treatment follow-up indicated sustained benefits of MI+HC and MI-only relative to control. Brief interventions can be successfully used to reduce non-injection drug use in HIV primary care. IVR-based technology may not be sufficiently engaging to be effective. Future studies should investigate mobile technology to deliver a more engaging version of HealthCall to diverse substance abusing populations. Copyright © 2016 Elsevier Inc. All rights reserved.

    Advances in fractional analysis suggest a new way for the physics understanding of Riemann's conjecture. It asserts that, if s is a complex number, the non trivial zeros of zeta function 1/(ζ(s)) =Σ n=1 ∞ (μ(n))/(n s ) in the gap [0, 1], is characterized by s=1/2 (1+2iθ). This conjecture can be understood as a consequence of 1/2-order fractional differential characteristics of automorph dynamics upon opened punctuated torus with an angle at infinity equal to π/4. This physical interpretation suggests new opportunities for revisiting the cryptographic methodologies

    Full Text Available It is agreed upon that among all the living things that have existed, only humans can speak. However, we do not know yet since when we have spoken. We find that Nietzsche left distinctive ideas on the origin of language. Reflecting on “eternal recurrence” and “overmen”, the concepts that Nietzsche made popular, we found out that he would agree on dating the origin of language from some 70,000 years ago when the human population shrank drastically to as low as 2,000 in the wake of the super-volcanic eruption at Lake Toba. At that time, the eternal recurrence that had shackled our ancestors for a long time suddenly disappeared and the small band of surviving members could not help becoming overmen or supermen of entire human species. We ascertained the conjecture with the latest development in evolution theory, archaeology and anatomical analysis on human fossils.

    This self-contained monograph provides systematic, instructive analysis of second-order rational difference equations. After classifying the various types of these equations and introducing some preliminary results, the authors systematically investigate each equation for semicycles, invariant intervals, boundedness, periodicity, and global stability. Of paramount importance in their own right, the results presented also offer prototypes towards the development of the basic theory of the global behavior of solutions of nonlinear difference equations of order greater than one. The techniques and results in this monograph are also extremely useful in analyzing the equations in the mathematical models of various biological systems and other applications. Each chapter contains a section of open problems and conjectures that will stimulate further research interest in working towards a complete understanding of the dynamics of the equation and its functional generalizations-many of them ideal for research project...

These statistics are concerning given that many supplements are taken based on purely "anecdotal" evidence. Many nutraceuticals are thought to have anti-inflammatory or anti-oxidant effects. Given that dystrophic pathology is exacerbated by inflammation and oxidative stress these nutraceuticals could have some therapeutic benefit for Duchenne Muscular Dystrophy (DMD). This review gathers and evaluates the peer-reviewed scientific studies that have used nutraceuticals in clinical or pre-clinical trials for DMD and thus separates the credible from the conjecture.

  8. The Role of Oxytocin in Parenting and as Augmentative Pharmacotherapy: Critical Issues and Bold Conjectures.

    2016-08-01

    Despite the sometimes heated debate about the validity of human oxytocin studies, experimental oxytocin research with intranasal administration is a growing field with promising preliminary findings. The effects of intranasally administered oxytocin compared to placebo on brain neural activity have been supported in animal studies and in human studies of neural resting state. In several studies, oxytocin sniffs have been shown to lead to down-regulation of amygdala activation in response to infant attachment vocalisations. Meta-analytic evidence shows that oxytocin enhances the salience of (emotional) stimuli, lowers stress and arousal, and elevates empathic concern and tender care, in particular for offspring and in-group members. Less firm evidence points at the amnestic effects of oxytocin. We also note that the average effect sizes of oxytocin experiments are small to modest, and that most studies include a small number of subjects and thus are seriously underpowered, which implies a high risk for publication bias and nonreplicability. Nevertheless, we argue that the power of within-subjects experiments with oxytocin has been underestimated. Much more work is needed, however, to create a firm knowledge base of the neural and behavioural effects of oxytocin. Human oxytocin research is still taking place in the context of discovery, in which bold conjectures are being generated. In the context of justification, these conjectures should subsequently be subjected to stringent attempts at refutations before we jump to theoretical or clinical conclusions. For this context of justification, we propose a multisite multiple replications project on the social stimuli salience enhancing effect of oxytocin. Clinical application of oxytocin is premature. Meta-analytically, the use of oxytocin in clinical groups tends to show only effectiveness in changing symptomatology in individuals with autism spectrum disorders but, even then, it is not yet a validated therapy and its

    Full Text Available Dans les «Aventures de Tintin» (Hergé ; 23 albums publiés entre 1930 et 1976, l’emploi fréquent et marqué du futur antérieur conjectural (FAC mérite une attention particulière. On sait que cette forme verbale, à la fois temporelle et modale, est privilégiée dans les récits d’investigation et de détection. Elle l’est également dans la bande dessinée d’aventure policière, où la conjonction du texte et de l’image lui donne un relief supplémentaire. Dans «Tintin», le FAC prend une valeur spécifique, marquée par le statut d’enquêteur omniscient du héros. Certes, comme d’autres détectives, Tintin utilise le FAC pour imposer ses abductions. Mais plus encore, cette forme verbale lui sert à figurer par le discours des évènements non dessinés. Autrement dit, à faire exister dans le phylactère un récit absent de la chaine narrative des images, et que le FAC lui permet d’insérer après coup dans l’ordre diégétique. En racontant ce qui ne s’est pas passé, Tintin contribue à l’économie du récit et assure son emprise sur le cours des choses. L’analyse des emplois caractéristiques du FAC dans «Tintin», au regard des contextes iconiques où ils apparaissent, met en évidence le caractère sémiotique et textuel de cette forme verbale et permet du même coup de renouveler l’approche qui en est faite habituellement dans les grammaires. Le corpus des occurrences de FAC compte en effet près de 50 cas (70% des futurs antérieurs dans les «Aventures» sont de type conjectural. L’ensemble donne lieu à une typologie à quatre niveaux : du point de vue de la forme (présence/absence d’indice de plausibilité, de type lexical ou syntaxique, du point de vue de la fonction (logique, sémantique, diégétique, du point de vue de la distribution (le savoir du lecteur comparé au savoir du locuteur et enfin du point de vue de la référence à l’évènement (scène évoquée, scène invoquée, sc

    Congestive heart failure is a severe chronic disease often associated with disorders that alter the mechanisms of excitation-contraction coupling that may result in an asynchronous left ventricular motion which may further impair the ability of the failing heart to eject blood. In recent years a therapeutic approach to resynchronize the ventricles (cardiac resynchronization therapy, CRT) has been performed through the use of a pacemaker device able to provide atrial-based biventricular stimulation. Atrial lead senses the spontaneous occurrence of cells depolarization and sends the information to the generator which, in turn, after a settled delay [atrioventricular (AV) delay], sends electrical impulses to both ventricles to stimulate their synchronous contraction. Recent studies performed on heart rate behavior of chronically implanted patients at different epochs after implantation have shown that CRT can lead to sustained overall improvement of heart function with a reduction in morbidity and mortality. At this moment, however, there are no studies about CRT effects on spontaneous heart activity of chronically implanted patients. We performed an experimental study in which the electrocardiographic signal of five subjects under chronic CRT was recorded during the activity of the pacemaker programmed at different AV delays and under spontaneous cardiac activity after pacemaker deactivation. The different behavior of heart rate variability during pacemaker activity and after pacemaker deactivation suggested the hypothesis of a phase resetting mechanism induced by the pacemaker stimulus on the sinoatrial (SA) node, a phenomenon already known in literature for aggregate of cardiac cells, but still unexplored in vivo. The constraints imposed by the nature of our study (in vivo tests) made it impossible to plan an experiment to prove our hypothesis directly. We therefore considered the best attainable result would be to prove the accordance of our data to the conjecture

  12. Winding out of the Swamp: Evading the weak gravity conjecture with F-term winding inflation?

    Directory of Open Access Journals (Sweden)

    Arthur Hebecker

    2015-09-01

    Full Text Available We present a new model of large field inflation along a winding trajectory in the field space of two axionic fields, where the “axions” originate from the complex structure moduli sector of a Calabi–Yau 3-fold at large complex structure. The winding trajectory arises from fixing one combination of axions by bulk fluxes and allows for a transplanckian effective field range. The inflaton potential arises from small “instantonic” corrections to the geometry and realises natural inflation. By working in a regime of large complex structure for two complex structure moduli the inflaton potential can be made subdominant without severe tuning. We also discuss the impact of the recent ‘no-go theorems’ for transplanckian axion periodicities on our work. Interestingly, our setup seems to realise a loophole pointed out in arXiv:1503.00795 and arXiv:1503.04783: our construction is a candidate for a string theory model of large field inflation which is consistent with the mild form of the weak gravity conjecture for axions.

    2017-03-01

    The classic Hegselmann-Krause ( HK) model for opinion dynamics consists of a set of agents on the real line, each one instructed to move, at every time step, to the mass center of the agents within a fixed distance R. In this work, we investigate the effects of noise in the continuous-time version of the model as described by its mean-field Fokker-Planck equation. In the presence of a finite number of agents, the system exhibits a phase transition from order to disorder as the noise increases. We introduce an order parameter to track the phase transition and resolve the corresponding phase diagram. The system undergoes a phase transition for small R but none for larger R. Based on the stability analysis of the mean-field equation, we derive the existence of a forbidden zone for the disordered phase to emerge. We also provide a theoretical explanation for the well-known 2 R conjecture, which states that, for a random initial distribution in a fixed interval, the final configuration consists of clusters separated by a distance of roughly 2 R. Our theoretical analysis confirms previous simulations and predicts properties of the noisy HK model in higher dimension.

  14. Testing holographic conjectures of complexity with Born-Infeld black holes

    In this paper, we use Born-Infeld black holes to test two recent holographic conjectures of complexity, the ''Complexity = Action'' (CA) duality and ''Complexity = Volume 2.0'' (CV) duality. The complexity of a boundary state is identified with the action of the Wheeler-deWitt patch in CA duality, while this complexity is identified with the spacetime volume of the WdW patch in CV duality. In particular, we check whether the Born-Infeld black holes violate the generalized Lloyd bound: C ≤ (2)/(πℎ) [(M - QΦ) - (M - QΦ){sub gs}], where gs stands for the ground state for a given electrostatic potential. We find that the ground states are either some extremal black hole or regular spacetime with nonvanishing charges. For Born-Infeld black holes, we compute the action growth rate at the late-time limit and obtain the complexities in CA and CV dualities. Near extremality, the generalized Lloyd bound is violated in both dualities. Near the charged regular spacetime, this bound is satisfied in CV duality but violated in CA duality. When moving away from the ground state on a constant potential curve, the generalized Lloyd bound tends to be saturated from below in CA duality. (orig.)

  15. Differential premises arising from differential socialization of the sexes: some conjectures.

    Science.gov (United States)

    Block, J H

    1983-12-01

    The sex-differentiated socialization emphases of parents and other representatives of societal institutions are considered as they influence the personality development and behavioral orientations of males and females. Specifically, sex-differentiated socialization emphases, "shaping" behaviors, and teaching styles are evaluated with regard to the nature of the "meta-messages" conveyed to boys and girls during their early, formative years. These messages are assumed to differentially influence the self-concepts evolved, ego structures, personal goals, and the cognitive-adaptational heuristics of boys and of girls. Differences in the socialization environments experienced by the 2 sexes can be seen as related to gender differences in personality characteristics. To integrate the empirical findings surrounding gender differences in personality and socialization experience, some conjectures are offered regarding the different self- and world views our current culture may be creating and fostering in males and in females. The potential and even likely influence of biological factors conjoined with the bidirectional effects of child and parent interaction are recognized as confounded with an interpretation in terms of differential socialization. But also, it is noted that until the effects of differential socialization are specifically evaluated by cultural, subcultural, or individual family changes, the role of biological and bidirectional factors cannot be assessed.

    Volume changes in chemically reactive materials, such as hydrating cement, play a critical role in many engineering applications that require precise estimates of stress and pressure developments. But a means to determine bulk volume changes in the absence of other deformation mechanisms related to thermal, pressure and load variations, is still missing. Herein, we present such a measuring devise, and a hybrid experimental-theoretical technique that permits the determination of colloidal eigenstresses. Applied to cementitious materials, it is found that bulk volume changes in saturated cement pastes at constant pressure and temperature conditions result from a competition of repulsive and attractive phenomena that originate from the relative distance of the solid particles - much as Henry Louis Le Châtelier, the father of modern cement science, had conjectured in the late 19th century. Precipitation of hydration products in confined spaces entails a repulsion, whereas the concurrent reduction in interparticle distance entails activation of attractive forces in charged colloidal particles. This cross-over from repulsion to attraction can be viewed as a phase transition between a liquid state (below the solid percolation) and the limit packing of hard spheres, separated by an energy barrier that defines the temperature-dependent eigenstress magnitude.

  3. Vertical and horizontal processes in the global atmosphere and the maximum entropy production conjecture

    Directory of Open Access Journals (Sweden)

    S. Pascale

    2012-01-01

    Full Text Available The objective of this paper is to reconsider the Maximum Entropy Production conjecture (MEP in the context of a very simple two-dimensional zonal-vertical climate model able to represent the total material entropy production due at the same time to both horizontal and vertical heat fluxes. MEP is applied first to a simple four-box model of climate which accounts for both horizontal and vertical material heat fluxes. It is shown that, under condition of fixed insolation, a MEP solution is found with reasonably realistic temperature and heat fluxes, thus generalising results from independent two-box horizontal or vertical models. It is also shown that the meridional and the vertical entropy production terms are independently involved in the maximisation and thus MEP can be applied to each subsystem with fixed boundary conditions. We then extend the four-box model by increasing its resolution, and compare it with GCM output. A MEP solution is found which is fairly realistic as far as the horizontal large scale organisation of the climate is concerned whereas the vertical structure looks to be unrealistic and presents seriously unstable features. This study suggest that the thermal meridional structure of the atmosphere is predicted fairly well by MEP once the insolation is given but the vertical structure of the atmosphere cannot be predicted satisfactorily by MEP unless constraints are imposed to represent the determination of longwave absorption by water vapour and clouds as a function of the state of the climate. Furthermore an order-of-magnitude estimate of contributions to the material entropy production due to horizontal and vertical processes within the climate system is provided by using two different methods. In both cases we found that approximately 40 mW m−2 K−1 of material entropy production is due to vertical heat transport and 5–7 mW m−2 K−1 to horizontal heat transport.

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

    CERN Document Server

    1998-01-01

    This introduction to the recent exciting developments in the applications of model theory to algebraic geometry, illustrated by E. Hrushovski's model-theoretic proof of the geometric Mordell-Lang Conjecture starts from very basic background and works up to the detailed exposition of Hrushovski's proof, explaining the necessary tools and results from stability theory on the way. The first chapter is an informal introduction to model theory itself, making the book accessible (with a little effort) to readers with no previous knowledge of model theory. The authors have collaborated closely to achieve a coherent and self- contained presentation, whereby the completeness of exposition of the chapters varies according to the existence of other good references, but comments and examples are always provided to give the reader some intuitive understanding of the subject.

    Background: Motivation is one of the most important factors for safety behaviour and for implementing change in general. However, theoretical and psychometric studies of safety performance have traditionally treated safety motivation, safety compliance and safety participation unidimensionally....... At the same time many motivation questionnaire items are seldom founded on theory and/or do not account for the theories’ ontological and epistemological differences, e.g. of how knowledge, attitude and action are related. Present questionnaire items tap into occupational safety motivation in asking whether...... or not respondents ‘are’ motivated and whether they feel that safety is important or worthwhile. Another important aspect is ‘what’ motivates workers to comply to and participate in safety. The aim of this article is to introduce a new theory-based occupational safety motivation scale which is validated...

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

    2018-01-01

    Approximately 11,000 people die in Scotland each year as a result of smoking-related causes. Quitting smoking is relatively easy; maintaining a quit attempt is a very difficult task with success rates for unaided quit attempts stubbornly remaining in the single digits. Pharmaceutical treatment can improve these rates by lowering the overall reward factor of nicotine. However, these and related nicotine replacement therapies do not operate on, or address, the spatial and contextual aspects of smoking behaviour. With the ubiquity of smartphones that can log spatial, quantitative and qualitative data related to smoking behaviour, there exists a person-centred clinical opportunity to support smokers attempting to quit by first understanding their smoking behaviour and subsequently sending them dynamic messages to encourage health behaviour change within a situational context. We have built a smartphone app-MapMySmoke-that works on Android and iOS platforms. The deployment of this app within a clinical National Health Service (NHS) setting has two distinct phases: (1) a 2-week logging phase where pre-quit patients log all of their smoking and craving events; and (2) a post-quit phase where users receive dynamic support messages and can continue to log craving events, and should they occur, relapse events. Following the initial logging phase, patients consult with their general practitioner (GP) or healthcare provider to review their smoking patterns and to outline a precise, individualised quit attempt plan. Our feasibility study consists of assessment of an initial app version during and after use by eight patients recruited from an NHS Fife GP practice. In addition to evaluation of the app as a potential smoking cessation aid, we have assessed the user experience, technological requirements and security of the data flow. In an initial feasibility study, we have deployed the app for a small number of patients within one GP practice in NHS Fife. We recruited eight

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

  1. How to Motivate Employees?

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

    Full Text Available Crowdsourcing is a way to access a global crowd of talented people and to channel their talent and creative effort towards some useful endeavour. Technology entrepreneurs who may have limited resources, especially during the start-up phase of the business, will be attracted to crowdsourcing as a means to access funding, knowledge, subject matter experts, and resources on a global scale. In this article, we review the published research on crowdsourcing as it relates to motivation, and distil the insights from that research that will be useful to technology entrepreneurs. First, we organize the published research into three streams according to crowd type: i task-based public crowd, ii information-exchange public crowd, and iii employee-based crowd. Next, we identify the motivational drivers common to all streams as well as the motivational drivers that are unique to each stream. Finally, we offer five recommendations for technology entrepreneurs seeking to apply crowdsourcing.

Nonetheless, public sector organizations increasingly rely on extrinsic motivation factors such as monetary incentives to motivate...... employees.

    2009-07-01

    This paper discussed social motivations related to household energy conservation. The aim of the study was to explore how technology can be designed and used in the home to encourage sustainable energy use. The basic techniques used to motivate sustainable energy action included behaviour change techniques; information techniques; positive motivational techniques; and coercive motivational techniques. The psychological theories used in the study included cognitive dissonance as a means of reminding people of the inconsistency of their attitudes towards energy and their behaviour, and utility theory as a means of determining personal motivations for energy conservation. The study showed that people are more motivated to act when presented with personalized information and monetary losses as opposed to monetary gain. Social value orientation and self-reflection motivations were also considered. The study showed that pro-social orientation can be used in the form of ambient displays located in public areas of the home. Self-reflection can be encouraged by allowing family members to annotate visualizations containing a history of their energy consumption data. Results of the study will be used to design actual feedback visualizations of energy use. 18 refs.

    2018-02-26

    The aim was to obtain insight into the factors in the work environment that motivate or demotivate a medical specialist during his/her working day. A qualitative ethnographic design was used, and a constructivist approach was adopted with the Self-Determination theory of motivation as a framework. Six medical specialists from VU University Medical Center in the Netherlands, recruited through convenience, snowball, and purposive sampling, were shadowed for one day each. Data were transcribed and open-coded. Themes were finalized through discussion and consensus. Sixty hours of observation data identified motivating and demotivating factors categorized into four themes that are important for specialists' motivation. Informational technology issues are demotivating factors. Working with colleagues can be both a motivating and demotivating factor, e.g., filling in for each other through feelings of relatedness was motivating. Being in control of one's planning through feelings of autonomy was motivating. Furthermore, patient care and teaching, especially in combination, stimulated specialists' motivation. Regarding the design of the study, we found that situational motivation is indeed observable. The basic psychological needs autonomy, competence, and relatedness are important for specialists' motivation. Investing in a more motivating, open, transparent, and basic-needs- supportive work environment for medical specialists is necessary. Keywords: Continuing professional development, motivation, medical specialists, self-determination theory, qualitative research.

    Full Text Available The paper analyzes the relationship between motivation and volitional processes as described by current motivation theories. The root of the separation between both moments of behavioris traced back to Tetens and Kant’s threefold view of the mind. Sensory perception is reduced to feeling and the will to energy without a proper object. The history of this conception isoutlined. Nuttin’s motivation theory is presented as an alternative to the limitations of other contemporary theories. Some educational consequences are sketched out.

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

    Science.gov (United States)

    Schumm, Maximiliane F.; Bogner, Franz X.

    2016-02-01

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

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

    Science.gov (United States)

    Choi, Jimmy; Choi, Kee-Hong; Reddy, Felice; Fiszdon, Joanna M.

    2014-01-01

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

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

  5. Variation of Seismic Velocity Structure around the Mantle Transition Zone and Conjecture of Deep Water Transport by Subducted Slabs

    Tajima, F. C.; Stahler, S. C.; Ohtani, E.; Yoshida, M.; Sigloch, K.

    2011-12-01

    Seismic tomography models published in the past two decades determined common long-wavelength features of subducting plates as high velocity anomalies and upwelling plumes as low velocity anomalies, and have led to a new class of high-resolution three-dimensional (3D) modeling of global mantle convection with a link to tomography models [e.g., Becker and Boschi, 2002; Ritsema et al., 2007; Schuberth et al., 2009a,b]. However, even such high resolution numerical models do not account for the variation associated with different behaviors of subducting plates as they enter the mantle transition zone (MTZ), i.e., some flatten to form stagnant slabs with a large lateral extent and others descend further into the lower mantle. There are conventional interpretations applied for the cause of variation of the subducted slab behaviors, i.e., temperature difference due to different plate age, different geochemical compositions, different water content and subsequent possible reduction of viscosity etc., which could be taken as non-unique and somewhat equivocal. These parameters and conditions have been tested in two-dimensional numerical simulations, while the water content in the MTZ or the mechanisms of hydration and dehydration through subduction process are still in the realm of conjecture. Recent models of seismic P- and SH-wave velocities derived for the mantle structure beneath northeast China [Wang and Niu, 2010; Ye et al., 2011] using reflectivity synthetics with data from the dense Chinese networks of broadband seismic instruments, show a broader 660 km discontinuity (by about 30 to 70 km) and slower shear velocities above the MTZ than a global standard model iasp91 (Kennett and Engdahl, 1991). These features were interpreted with a mixture of different chemical properties which show delayed phase transformation, and effects of water above the flattened slab. Nonetheless, the SH-wave model has a structure similar to model TNA above the MTZ, which was derived for the

    Motivic analysis provides very detailed understanding of musical composi- tions, but is also particularly difficult to formalize and systematize. A computational automation of the discovery of motivic patterns cannot be reduced to a mere extraction of all possible sequences of descriptions....... The systematic approach inexorably leads to a proliferation of redundant structures that needs to be addressed properly. Global filtering techniques cause a drastic elimination of interesting structures that damages the quality of the analysis. On the other hand, a selection of closed patterns allows...... for lossless compression.

  20. Motivation in computer-assisted instruction.

    Science.gov (United States)

    Hu, Amanda; Shewokis, Patricia A; Ting, Kimberly; Fung, Kevin

    2016-08-01

    Computer-aided instruction (CAI) is defined as instruction in which computers play a central role as the means of information delivery and direct interaction with learners. Computer-aided instruction has become mainstream in medical school curricula. For example, a three-dimensional (3D) computer module of the larynx has been created to teach laryngeal anatomy. Although the novelty and educational potential of CAI has garnered much attention, these new technologies have been plagued with low utilization rates. Several experts attribute this problem to lack of motivation in students. Motivation is defined as the desire and action toward goal-oriented behavior. Psychologist Dr. John Keller developed the ARCS theory of motivational learning, which proposed four components: attention (A), relevance (R), concentration (C), and satisfaction (S). Keller believed that motivation is not only an innate characteristic of the pupil; it can also be influenced by external factors, such as the instructional design of the curriculum. Thus, understanding motivation is an important step to designing CAI appropriately. Keller also developed a 36-item validated instrument called the Instructional Materials Motivation Survey (IMMS) to measure motivation. The objective of this study was to study motivation in CAI. Medical students learning anatomy with the 3D computer module will have higher laryngeal anatomy test scores and higher IMMS motivation scores. Higher anatomy test scores will be positively associated with higher IMMS scores. Prospective, randomized, controlled trial. After obtaining institutional review board approval, 100 medical students (mean age 25.5 ± 2.5, 49% male) were randomized to either the 3D computer module (n = 49) or written text (n = 51). Information content was identical in both arms. Students were given 30 minutes to study laryngeal anatomy and then completed the laryngeal anatomy test and IMMS. Students were categorized as either junior (year 1

  5. Motives of terrorist acts

    Directory of Open Access Journals (Sweden)

    Krstić Marko

    2015-01-01

    Full Text Available Terrorism is a relatively new phenomenon, and data on terrorist motivations and psychological profiles of terrorists are fairly scarce and limited. In theory, there is a large number of quantitative analyses of collective violence, murder, and crime, however, none of these can be identified with terrorism. Most current studies do not consider a great heterogeneity of terrorists, and numerous practical, conceptual, and psychological barriers slow down the science of learning about terrorism. Psychology, as a science of behavior, certainly makes a great contribution to the study of terrorism as a very complex phenomenon. The aim of this paper is to analyze and synthesize social and psychological determinants which contribute to the development of terrorist motives, and to elaborate on those facts which have been discussed in scientific and professional literature so far.

    Huf, P. A.; Carminati, J.

    2018-01-01

    In this paper we explore the use of a new algebraic software package in providing independent covariant proof of a conjecture in general relativity. We examine the proof of two sub-cases of the shear-free conjecture σ =0 => ω Θ =0 by Senovilla et al. (Gen. Relativ. Gravit 30:389-411, 1998): case 1: for dust; case 2: for acceleration parallel to vorticity. We use TensorPack, a software package recently released for the Maple environment. In this paper, we briefly summarise the key features of the software and then demonstrate its use by providing and discussing examples of independent proofs of the paper in question. A full set of our completed proofs is available online at http://www.bach2roq.com/science/maths/GR/ShearFreeProofs.html. We are in agreeance with the equations provided in the original paper, noting that the proofs often require many steps. Furthermore, in our proofs we provide fully worked algebraic steps in such a way that the proofs can be examined systematically, and avoiding hand calculation. It is hoped that the elucidated proofs may be of use to other researchers in verifying the algebraic consistency of the expressions in the paper in question, as well as related literature. Furthermore we suggest that the appropriate use of algebraic software in covariant formalism could be useful for developing research and teaching in GR theory.

    Forscher, Patrick S.; Cox, William T. L.; Graetz, Nicholas; Devine, Patricia G.

    2015-01-01

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

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

  12. Neuroscientific model of motivational process.

    Kim, Sung-Il

    2013-01-01

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

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

  14. The Outer Space as an Educational Motivation

    Pérez-Pérez, Melquíades; Hernández-López, Montserrat

    2017-06-01

    STEAM is an educational approach to learning that uses Science, Technology, Engineering, the Arts and Mathematics as access points for guiding student inquiry, dialogue, and critical thinking. The end results are students who take thoughtful risks, engage in experiential learning, persist in problem-solving, embrace collaboration, and work through the creative process. The Outer Space is a window to the past and the future of our travel around the history of the Universe and can be used as a educational tool in primary and secondary education. This paper talks about the integration of the resources of European Space Agency, Space Awareness, Nuclio, Scientix and Schoolnet as motivation to integrate STEAM methodology in secondary education.

  15. Consumer concerns: motivating to action.

    Science.gov (United States)

    Bruhn, C M

    1997-01-01

    Microbiologic safety is consumers' most frequently volunteered food safety concern. An increase in the level of concern in recent years suggests that consumers are more receptive to educational information. However, changing lifestyles have lessened the awareness of foodborne illness, especially among younger consumers. Failure to fully recognize the symptoms or sources of foodborne disease prevents consumers from taking corrective action. Consumer education messages should include the ubiquity of microorganisms, a comprehensive description of foodborne illnesses, and prevention strategies. Product labels should contain food-handling information and warnings for special populations, and foods processed by newer safety-enhancing technologies should be more widely available. Knowledge of the consequences of unsafe practices can enhance motivation and adherence to safety guidelines. When consumers mishandle food during preparation, the health community, food industry, regulators, and the media are ultimately responsible. Whether inappropriate temperature control, poor hygiene, or another factor, the error occurs because consumers have not been informed about how to handle food and protect themselves. The food safety message has not been delivered effectively.

    Full Text Available Even though philanthropy tends to be considered a sociological theme rather than an economic one, it poses a number of questions that challenge economists as well. We chose to address the following: How can economists contribute to the theories related to philanthropy? We examine some terms that are used in public economics theory and use them to explore the issues of philanthropy like Samaritan’s Dilemma, the Prisoner’s Dilemma, and the Free-Rider Problem, which we consider to be interesting and inspiring (Stone, 2008. We have to find and identify the social values of donors and volunteers rather than their economic values, because economists are not fully able to explain empathy, altruism, and helpful behaviour using traditional economic principles (Rutherford, 2008. The theoretical frame is supported by relevant empirical data. Before starting a large-scale survey, we decided to conduct smaller pre-research probes into people’s attitudes towards altruism, philanthropy, and giving. Even though our sample was not fully representative, the responses that we collected generated interesting findings about people’s views and attitudes. The first wave of data was collected between February and April 2009; the second wave between February and April 2010.Because of this pilot research mission and because of the budget restriction too, the non-representative sample of 823 respondents has been used; students of our Public Economics study programme were used as interviewers. They have also obtained a proper training of the professional sociologist. Students utilized the face to face interviewing method; non-standardized questions were immediately recorded into the reply form.

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

  1. Motivations for Extradyadic Infidelity Revisited.

    Selterman, Dylan; Garcia, Justin R; Tsapelas, Irene

    2017-12-15

    Relationship infidelities are motivated by many distinct factors, with previous research indicating motivations of dissatisfaction, neglect, anger, and sexual desire (Barta & Kiene, 2005). We expand on this by demonstrating additional, empirically distinct motivations for infidelity. Using an Internet-based questionnaire, participants (N = 495), most of whom were young adults, self-reported their infidelities. In addition to evidence for previously studied motivations, our data demonstrate additional factors, including lack of love ("I had 'fallen out of love with' my primary partner"), low commitment ("I was not very committed to my primary partner"), esteem ("I wanted to enhance my popularity"), gaining sexual variety ("I wanted a greater variety of sexual partners"), and situational factors ("I was drunk and not thinking clearly"). Our results also show personality correlates with infidelity motivations. Consistent with predictions, attachment insecurity was associated with motivations of anger, lack of love, neglect, low commitment, and esteem, while unrestricted sociosexual orientation was associated with sexual variety. Implicit beliefs (e.g., growth, destiny, romanticism) were differentially associated with sexual desire, low commitment, lack of love, and neglect. These findings highlight multifaceted motivations underlying infidelity, moving beyond relationship deficit models of infidelity, with implications for research and psychotherapy involving people's romantic and sexual relationships.

  2. Harnessing motivation to alleviate neglect

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The syndrome of spatial neglect results from the combination of a number of deficits in attention, with patients demonstrating both spatially lateralised and non-lateralised impairments. Previous reports have hinted that there may be a motivational component to neglect and that modulating this might alleviate some of the debilitating symptoms. Additionally, recent work on the effects of reward on attention in healthy participants has revealed improvements across a number of paradigms. As the primary deficit in neglect has been associated with attention, this evidence for reward’s effects is potentially important. However, until very recently there have been few empirical studies addressing this potential therapeutic avenue. Here we review the growing body of evidence that attentional impairments in neglect can be reduced by motivation, for example in the form of preferred music or anticipated monetary reward, and discuss the implications of this for treatments for these patients. Crucially these effects of positive motivation are not observed in all patients with neglect, suggesting that the consequences of motivation may relate to individual lesion anatomy. Given the key role of dopaminergic systems in motivational processes, we suggest that motivational stimulation might act as a surrogate for dopaminergic stimulation. In addition, we consider the relationship between clinical post stroke apathy and lack of response to motivation.

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

Teacher will see some of the students are very motivated, motivated or even feeling ignored in studying English. The learners who have contacted with English will find that some features are quite easy and extremely difficult. One of the more complicated problems of second or foreign languages learning and  teaching has been to define and apply the construct of motivation in the classroom. Motivation is a concept without physical reality, we cannot see motivation; we see effort, interest, attitude and desire. For speaking, it is important first to give competence and then performance. Competence is more likely to the extent a communicator is motivated to be so. Motivation is the extent to which a communicator is drawn towards or pushed away from communicating competently in a given context then performed. This is a descriptive  quantitative research. The data obtained from the questionnaire distributed and analyzed to get the result.  The date taken from the students of Muhammadiyah 1 Senior High School Gresik in Easy-Speaking course.

    Full Text Available A major concern in the last few years has been the fact that the Cultural Centers are keeping distance with what they have been established for, and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. Cultural Centers, as urban public spaces in the last two decades, have been the subject of ideological discussions and debates. In such spaces, consumption is not just limited to the utilization of programs in cultural centers, but the consumption of Cultural Center’s spaces prevail the consumption of activities and programs in these Cultural Centers. Such consumption is associated with the introduction of several social and cultural definitions. The main purpose of this study is to identify the application and implications of the Cultural Centers for the youth in Tehran and the motivations and functions resulting from the consumption of these spaces. The study uses the method of basic theorization for the data collection and analysis. For this purpose, 25 of clients in Bahman, Shafagh, Honar, Kar, Quran and Eshragh Cultural Centers located in Tehran have been the subjects of in-depth interview. Totally, the results of this study show that Cultural Centers are a part of rites of transition to the adulthood for the youth of Tehran. They satisfy many of the needs related to their age, and in one word, they draw their own painting on the canvass of this public space. The Present study is going to describe and elaborate the painting patterns and interference in and intervention with the public space of the Cultural Centers. In this study, Cultural Center is considered as a context and its several implications for the users of this space are analyzed.

    Medical schools try to implement selection procedures that will allow them to select the most motivated students for their programs. Though there is a general feeling that selection stimulates student motivation, conclusive evidence for this is lacking. The current study aims to use the perspective of Self-determination Theory (SDT) of motivation as a lens to examine how medical students' motivation differs in relation to different selection procedures. The hypotheses were that 1) selected students report higher strength and autonomous motivation than non-selected students, and 2) recently selected students report higher strength and autonomous motivation than non-selected students and students who were selected longer ago. First- (Y1) and fourth-year (Y4) medical students in the six-year regular programme and first-year students in the four-year graduate entry programme (GE) completed questionnaires measuring motivation strength and type (autonomous-AM, controlled-CM). Scores were compared between students admitted based on selection, lottery or top pre-university GPA (top GPA) using ANCOVAs. Selected students' answers on open-ended questions were analysed using inductive thematic analysis to identify reasons for changes in motivation. The response rate was 61.4 % (n = 357). Selected students (Y1, Y4 and GE) reported a significantly higher strength of motivation than non-selected students (Y1 and Y4 lottery and top GPA) (p students (Y1 and GE) reported significantly higher strength (p students (lottery and top GPA) and Y4 students who were selected three years ago. Students described that being selected enhanced their motivation as they felt autonomous, competent and that they belonged to a special group. These reported reasons are in alignment with the basic psychological needs described by Self-Determination Theory as important in enhancing autonomous motivation. A comprehensive selection procedure, compared to less demanding admission procedures, does

  16. Motivation for pilgrimage: using theory to explore motivations

    2010-01-01

    Full Text Available This article is a discussion of the motivations for pilgrimage and it will draw upon theories of motivation to explore the continuing attraction of pilgrimage in contemporary times. This discussion is located within the field of Event Management. Event Management is a fast growing discipline which focuses on the design, production and management of planned events, such as festivals, celebrations, conferences, fund-raisers and so on. Clearly pilgrimages, as planned events, fit into this definition. In this context, it is essential to recognise the importance of understanding the motives and needs of event customers so that we can plan to help our customers satisfy their motives. Whilst it might seem abhorrent and commercial to talk of pilgrims as customers, pilgrimages and religious sites have become more and more commodified and increasingly are deemed to need professional management. Key theories of motivation will be compared in order to identify the prime motivating factors underpinning people’s decisions to make pilgrimages.

    Motivation is suggested as an important factor in pediatric motor rehabilitation. Therefore, we reviewed the existing evidence of (motivational) motor rehabilitation paradigms, and how motivation influences rehabilitation outcome using self-determination theory as conceptual framework. PubMed and Web-of-Science databases were systematically searched until June 2015. Data were independently extracted and critiqued for quality by three authors. Studies reporting motivational aspects were included. Most studies examined new technology (e.g., virtual reality [VR]). Out of 479 records, three RCT, six case-control, and six non-comparative studies were included with mixed quality. Motivation was rarely reported. Training individualization to the child's capabilities with more variety seemed promising to increase motivation. Motivation increased when the exercises seemed helpful for daily activities. Motivation in pediatric rehabilitation should be comprehensively assessed within a theoretical framework as there are indications that motivated children have better rehabilitation outcomes, depending on the aspect of motivation.

    Full Text Available This is a reflection article, methodologically based on research into and theoretical and conceptual review of the motivational condition in educational evaluation. At the same time, some inquiries about the motivational problems in this education process are made. The objective is to examine what the motivational condition within the process ofeducational evaluation is. On the one hand, educational evaluation is a tool that attests to the knowledge, on the other hand, however, it prevents students from strengthening their interest both in the participation in the specific testing activity and in their learning, since it lays emphasis on extrinsic factors, such as grade, which make students lose and distort their intrinsic motivation to learn. Therefore, the evaluation proposal arisen from the construct of motivation is thought to generate in students positive sensations standing even after goals are obtained. Likewise, it must promote liveliness, integration and psychological health, in order to get students to fulfill their needs and obtain psychological welfare in the classroom.

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

  6. Inspiring Student Self-Motivation

    2007-01-01

    Full Text Available While normally appreciative of the invitation to join colleagues in a discussion of pedagogy and what “works” in the classroom, I have in most instances reluctantly participated in discussion of student motivation. I dip my toe into this philosophical quagmire only if permitted license to substitute the phrase student inspiration in place of student motivation. I also find it helpful to turn the rhetorical tables, as it were, and consider self-motivation on the part of students. The concept of individuals who hold some sense of self that a classroom mentor may nurture through student inspiration is one in which I place a modicum of trust. To “inspire” is literally to “breathe in,” to actively pull sustenance from a proffered external source. Active student determination based on some sense of self may couple with instructor inspiration to promote academic success.

    Full Text Available Research studies show that serious games help to motivate users in rehabilitation processes, and rehabilitation results are better when users are motivated. In long term rehabilitation for maintaining capacities, the demotivation of chronic patients is common. In this work, we have implemented balance rehabilitation video game for cerebral palsy patients. The video game was developed using the prototype development paradigm and following desirable features for rehabilitation serious games presented in the literature. We have tested the video game with a set of users who abandoned therapy due to demotivation in the previous year. Results show that the set of users improved their balance and motivation.

    Full Text Available Nowadays, when the welfare state is a responsibility of the entire society, organizations in the private sector assume co-responsibility for social issues. They are also pressured by the challenges presented by technological advances and the globalization , involving new parameters and requirements for quality. In this context, the concept of Corporate Social Responsibility (RSC emerges as an option for solutions to the issues related to the company and the whole community. Among the actions of the RSC is the Corporate Volunteering-program, which aims to promote / encourage employes to do voluntary work. A central issue when talking about volunteering is the withdrawal of these (SILVA and FEITOSA, 2002; TEODÓSIO, 1999 and, in accordance with the Community Solidarity (1997, one of the possible causes for the withdrawal is the lack of clarity as to the motives and expectations that lead the person to volunteer themselves. This study uses qualitative research and triangulation of feedback from volunteers, coordinators of volunteers and social organizations, to present a framework from which it is possible to analyze the various motivations for the volunteer work. Key words: Corporate Volunteering program. Volunteering. Corporate social responsibility.
