  2. Mentoring to develop research selfefficacy, with particular reference to previously disadvantaged individuals


    S. Schulze


    The development of inexperienced researchers is crucial. In response to the lack of research self-efficacy of many previously disadvantaged individuals, the article examines how mentoring can enhance the research self-efficacy of mentees. The study is grounded in the self-efficacy theory (SET) – an aspect of the social cognitive theory (SCT). Insights were gained from an in-depth study of SCT, SET and mentoring, and from a completed mentoring project. This led to the formulation of three basi...

  3. Developing an Asteroid Rotational Theory (United States)

    Geis, Gena; Williams, Miguel; Linder, Tyler; Pakey, Donald


    The goal of this project is to develop a theoretical asteroid rotational theory from first principles. Starting at first principles provides a firm foundation for computer simulations which can be used to analyze multiple variables at once such as size, rotation period, tensile strength, and density. The initial theory will be presented along with early models of applying the theory to the asteroid population. Early results confirm previous work by Pravec et al. (2002) that show the majority of the asteroids larger than 200m have negligible tensile strength and have spin rates close to their critical breakup point. Additionally, results show that an object with zero tensile strength has a maximum rotational rate determined by the object’s density, not size. Therefore, an iron asteroid with a density of 8000 kg/m^3 would have a minimum spin period of 1.16h if the only forces were gravitational and centrifugal. The short-term goal is to include material forces in the simulations to determine what tensile strength will allow the high spin rates of asteroids smaller than 150m.

  7. Mentoring to develop research selfefficacy, with particular reference to previously disadvantaged individuals

    S. Schulze


    Full Text Available The development of inexperienced researchers is crucial. In response to the lack of research self-efficacy of many previously disadvantaged individuals, the article examines how mentoring can enhance the research self-efficacy of mentees. The study is grounded in the self-efficacy theory (SET – an aspect of the social cognitive theory (SCT. Insights were gained from an in-depth study of SCT, SET and mentoring, and from a completed mentoring project. This led to the formulation of three basic principles. Firstly, institutions need to provide supportive environmental conditions that facilitate research selfefficacy. This implies a supportive and efficient collective system. The possible effects of performance ratings and reward systems at the institution also need to be considered. Secondly, mentoring needs to create opportunities for young researchers to experience successful learning as a result of appropriate action. To this end, mentees need to be involved in actual research projects in small groups. At the same time the mentor needs to facilitate skills development by coaching and encouragement. Thirdly, mentors need to encourage mentees to believe in their ability to successfully complete research projects. This implies encouraging positive emotional states, stimulating self-reflection and self-comparison with others in the group, giving positive evaluative feedback and being an intentional role model.

  8. A theory of neurolinguistic development. (United States)

    Locke, J L


    This article offers a developmental theory of language and the neural systems that lead to and subserve linguistic capabilities. Early perceptual experience and discontinuities in linguistic development suggest that language develops in four phases that occur in a fixed, interdependent sequence. In each phase of language, a unique ontogenetic function is accomplished. These functions have proprietary neural systems that vary in their degree of specialization. Of particular interest is an analytical mechanism that is responsible for linguistic grammar. This mechanism is time-locked and can only be turned on in the third phase. Confirming evidence is provided by children who are delayed in the second phase of the language learning process. These children store insufficient lexical material to activate their analytic mechanism. Inactivation behaves like damage, shifting language functions to homologous mechanisms in the nondominant hemisphere, thereby increasing functional and anatomical symmetry across the hemispheres. This atypical assembly of neurolinguistic resources produces functional but imperfect command of spoken language and may complicate learning of written language. The theory thus offers a different role for genetics and early experience, and a different interpretation of neuroanatomic findings, from those entertained in most other proposals on developmental language disorders.

  7. The development of elementary quantum theory

    CERN Document Server

    Capellmann, Herbert


    This book traces the evolution of the ideas that eventually resulted in the elementary quantum theory in 1925/26. Further, it discusses the essential differences between the fundamental equations of Quantum Theory derived by Born and Jordan, logically comprising Quantum Mechanics and Quantum Optics, and the traditional view of the development of Quantum Mechanics. Drawing on original publications and letters written by the main protagonists of that time, it shows that Einstein’s contributions from 1905 to 1924 laid the essential foundations for the development of Quantum Theory. Einstein introduced quantization of the radiation field; Born added quantized mechanical behavior. In addition, Born recognized that Quantum Mechanics necessarily required Quantum Optics; his radical concept of truly discontinuous and statistical quantum transitions (“quantum leaps”) was directly based on Einstein’s physical concepts.

  8. Rate of torque and electromyographic development during anticipated eccentric contraction is lower in previously strained hamstrings. (United States)

    Opar, David A; Williams, Morgan D; Timmins, Ryan G; Dear, Nuala M; Shield, Anthony J


    The effect of prior strain injury on myoelectrical activity of the hamstrings during tasks requiring high rates of torque development has received little attention. To determine if recreational athletes with a history of unilateral hamstring strain injury will exhibit lower levels of myoelectrical activity during eccentric contraction, rate of torque development (RTD), and impulse (IMP) at 30, 50, and 100 milliseconds after the onset of myoelectrical activity or torque development in the previously injured limb compared with the uninjured limb. Case control study; Level of evidence, 3. Twenty-six recreational athletes were recruited. Of these, 13 athletes had a history of unilateral hamstring strain injury (all confined to biceps femoris long head), and 13 had no history of hamstring strain injury. Following familiarization, all athletes undertook isokinetic dynamometry testing and surface electromyography (integrated EMG; iEMG) assessment of the biceps femoris long head and medial hamstrings during eccentric contractions at -60 and -180 deg·s(-1). In the injured limb of the injured group, compared with the contralateral uninjured limb, RTD and IMP was lower during -60 deg·s(-1) eccentric contractions at 50 milliseconds (RTD: injured limb, 312.27 ± 191.78 N·m·s(-1) vs uninjured limb, 518.54 ± 172.81 N·m·s(-1), P = .008; IMP: injured limb, 0.73 ± 0.30 N·m·s vs uninjured limb, 0.97 ± 0.23 N·m·s, P = .005) and 100 milliseconds (RTD: injured limb, 280.03 ± 131.42 N·m·s(-1) vs uninjured limb, 460.54 ± 152.94 N·m·s(-1), P = .001; IMP: injured limb, 2.15 ± 0.89 N·m·s vs uninjured limb, 3.07 ± 0.63 N·m·s, P contraction. Biceps femoris long head muscle activation was lower at 100 milliseconds at both contraction speeds (-60 deg·s(-1), normalized iEMG activity [×1000]: injured limb, 26.25 ± 10.11 vs uninjured limb, 33.57 ± 8.29, P = .009; -180 deg·s(-1), normalized iEMG activity [×1000]: injured limb, 31.16 ± 10.01 vs uninjured limb, 39.64

  12. Chaos theory perspective for industry clusters development (United States)

    Yu, Haiying; Jiang, Minghui; Li, Chengzhang


    Industry clusters have outperformed in economic development in most developing countries. The contributions of industrial clusters have been recognized as promotion of regional business and the alleviation of economic and social costs. It is no doubt globalization is rendering clusters in accelerating the competitiveness of economic activities. In accordance, many ideas and concepts involve in illustrating evolution tendency, stimulating the clusters development, meanwhile, avoiding industrial clusters recession. The term chaos theory is introduced to explain inherent relationship of features within industry clusters. A preferred life cycle approach is proposed for industrial cluster recessive theory analysis. Lyapunov exponents and Wolf model are presented for chaotic identification and examination. A case study of Tianjin, China has verified the model effectiveness. The investigations indicate that the approaches outperform in explaining chaos properties in industrial clusters, which demonstrates industrial clusters evolution, solves empirical issues and generates corresponding strategies.

  14. Endogenous growth theory and regional development policy

    Directory of Open Access Journals (Sweden)

    Cvetanović Slobodan


    Full Text Available The numerous versions of endogenous explanations of economic growth emphasize the importance of technological change driving forces, as well as the existence of appropriate institutional arrangements. Endogenous growth theory contributes to a better understanding of various experiences with long-term growth of countries and regions. It changes the key assumptions of the Neoclassical growth theory and participates in the modern regional development physiology explanation. Based on these conclusions, the paper: a explicates the most important theoretical postulates of the theory, b explains the most important factors of economic growth in the regions in light of the Endogenous growth theory messages and c emphasizes the key determinants of regional competitiveness which in our view is conceptually between the phenomena of micro- and macro-competitiveness and represents their necessary and unique connection. First of all, micro-competitiveness is transformed into a regional competitiveness; then regional competitiveness is transformed into a macro-competitiveness. In turn, macro - influences the microeconomic competitiveness, and the circle is closed. After that, the process starts over again.

  5. Development status of condensed cluster fusion theory

    International Nuclear Information System (INIS)

    Takahashi, Akito


    The condensed cluster fusion theory has been developed since 1989, under the view that dynamic ordering processes of confined transient clusters of D(H)-particles in catalytic surface sites, vacancies and global mesoscopic potential well of metal nanoparticles may induce simultaneous multi-body fusion reactions. One thorough answer is obtained for the condensation motion of clusters under platonic symmetry like 4D(H)/TSC, 6D(H)/RDC and 8D(H)/RDC and their fusion reaction rates. Theoretical analysis for initial dynamic clustering process on/in catalytic sites is still speculative and under searching a technique to combine the electron density functional method and the QM Langevin method.

  8. Shot peening: theory applications and recent development

    International Nuclear Information System (INIS)

    Zaid, A.I.O.


    Shot peening is a surface treatment process by which the surface of an elastic-plastic target material is subjected to multiple impact by spherical shots made of glass or hard steel in a defined and controlled manner. The multiple impact produces a dynamic compressive stress at the surface of the target, thereby effectively improving its mechanical behavior and eliminates cracks and imperfections hence improving the fatigue life and strength. In this paper, the theory and practice of the shot peening process are reviewed. The main parameters involved in the process and their effects on shot peening are presented and discussed which include: shot material, size and geometry, shot pressure and shot velocity, projection angle, exposure time, table rotational speed, standoff distance coverage, saturation and peening intensity. Furthermore, the effect of shot peening on fatigue life and fatigue strength of ferrous and non-ferrous materials together with other different industrial applications of the process are given. Recent developments in utilizing the shot peening process with welded parts and hard chromium plating aiming at improvement of their fatigue strength and their resistance to stress corrosion cracking are also presented and discussed. Finally, future development of the process are outlined and discussed. (author)

  9. Developing a domain theory defining and exemplifying a learning theory of progressive attainments. (United States)

    Bunderson, C Victor


    This article defines the concept of Domain Theory, or, when educational measurement is the goal, one might call it a "Learning Theory of Progressive Attainments in X Domain". The concept of Domain Theory is first shown to be rooted in validity theory, then the concept of domain theory is expanded to amplify its necessary but long neglected connection to design research disciplines. The development of a local learning theory of progressive attainments in the domain of Fluent Oral Reading is presented as an illustration. Such a theory is local to a defined domain of application, having well delineated boundaries. It depends on measures having a deep and valid connection to constructs, and the constructs back to the items or tasks at pertinent levels of the measurement scale. Thus instrument development and theory development, which occur in tandem, depend on establishing construct validity in a deep and thoroughgoing manner.

  10. Impact assessment procedures for sustainable development: A complexity theory perspective

    International Nuclear Information System (INIS)

    Nooteboom, Sibout


    The author assumes that effective Impact Assessment procedures should somehow contribute to sustainable development. There is no widely agreed framework for evaluating such effectiveness. The author suggests that complexity theories may offer criteria. The relevant question is 'do Impact Assessment Procedures contribute to the 'requisite variety' of a social system for it to deal with changing circumstances?' Requisite variety theoretically relates to the capability of a system to deal with changes in its environment. The author reconstructs how thinking about achieving sustainable development has developed in a sequence of discourses in The Netherlands since the 1970s. Each new discourse built on the previous ones, and is supposed to have added to 'requisite variety'. The author asserts that Impact Assessment procedures may be a necessary component in such sequences and derives possible criteria for effectiveness

  14. Development of the doppler electron velocimeter: theory.

    Energy Technology Data Exchange (ETDEWEB)

    Reu, Phillip L.


    Measurement of dynamic events at the nano-scale is currently impossible. This paper presents the theoretical underpinnings of a method for making these measurements using electron microscopes. Building on the work of Moellenstedt and Lichte who demonstrated Doppler shifting of an electron beam with a moving electron mirror, further work is proposed to perfect and utilize this concept in dynamic measurements. Specifically, using the concept of ''fringe-counting'' with the current principles of transmission electron holography, an extension of these methods to dynamic measurements is proposed. A presentation of the theory of Doppler electron wave shifting is given, starting from the development of the de Broglie wave, up through the equations describing interference effects and Doppler shifting in electron waves. A mathematical demonstration that Doppler shifting is identical to the conceptually easier to understand idea of counting moving fringes is given by analogy to optical interferometry. Finally, potential developmental experiments and uses of a Doppler electron microscope are discussed.

  15. How to Develop a Multi-Grounded Theory: the evolution of a business process theory

    Directory of Open Access Journals (Sweden)

    Mikael Lind


    Full Text Available In the information systems field there is a great need for different theories. Theory development can be performed in different ways – deductively and/or inductively. Different approaches with their pros and cons for theory development exists. A combined approach, which builds on inductive as well as deductive thinking, has been put forward – a Multi-Grounded Theory approach. In this paper the evolution of a business process theory is regarded as the development of a multi-grounded theory. This evolution is based on empirical studies, theory-informed conceptual development and the creation of conceptual cohesion. The theoretical development has involved a dialectic approach aiming at a theoretical synthesis based on antagonistic theories. The result of this research process was a multi-grounded business process theory. Multi-grounded means that the theory is empirically, internally and theoretically founded. This business process theory can be used as an aid for business modellers to direct attention towards relevant aspects when business process determination is performed.

  17. Development of a theory of implementation and integration: Normalization Process Theory

    Directory of Open Access Journals (Sweden)

    May Carl R


    Full Text Available Abstract Background Theories are important tools in the social and natural sciences. The methods by which they are derived are rarely described and discussed. Normalization Process Theory explains how new technologies, ways of acting, and ways of working become routinely embedded in everyday practice, and has applications in the study of implementation processes. This paper describes the process by which it was built. Methods Between 1998 and 2008, we developed a theory. We derived a set of empirical generalizations from analysis of data collected in qualitative studies of healthcare work and organization. We developed an applied theoretical model through analysis of empirical generalizations. Finally, we built a formal theory through a process of extension and implication analysis of the applied theoretical model. Results Each phase of theory development showed that the constructs of the theory did not conflict with each other, had explanatory power, and possessed sufficient robustness for formal testing. As the theory developed, its scope expanded from a set of observed regularities in data with procedural explanations, to an applied theoretical model, to a formal middle-range theory. Conclusion Normalization Process Theory has been developed through procedures that were properly sceptical and critical, and which were opened to review at each stage of development. The theory has been shown to merit formal testing.

    CERN Document Server

    Grigorenko, Alexander Ya; Grigorenko, Yaroslav M; Vlaikov, Georgii G


    This volume focuses on the relevant general theory and presents some first applications, namely those based on classical shell theory. After a brief introduction, during which the history and state-of-the-art are discussed, the first chapter presents the mechanics of anisotropic heterogeneous shells, covering all relevant assumptions and the basic relations of 3D elasticity, classical and refined shell models. The second chapter examines the numerical techniques that are used, namely discrete orthogonalization, spline-collocation and Fourier series, while the third highlights applications based on classical theory, in particular, the stress-strain state of shallow shells, non-circular shells, shells of revolution, and free vibrations of conical shells. The book concludes with a summary and an outlook bridging the gap to the second volume.

  3. Sampling theory, a renaissance compressive sensing and other developments

    CERN Document Server


    Reconstructing or approximating objects from seemingly incomplete information is a frequent challenge in mathematics, science, and engineering. A multitude of tools designed to recover hidden information are based on Shannon’s classical sampling theorem, a central pillar of Sampling Theory. The growing need to efficiently obtain precise and tailored digital representations of complex objects and phenomena requires the maturation of available tools in Sampling Theory as well as the development of complementary, novel mathematical theories. Today, research themes such as Compressed Sensing and Frame Theory re-energize the broad area of Sampling Theory. This volume illustrates the renaissance that the area of Sampling Theory is currently experiencing. It touches upon trendsetting areas such as Compressed Sensing, Finite Frames, Parametric Partial Differential Equations, Quantization, Finite Rate of Innovation, System Theory, as well as sampling in Geometry and Algebraic Topology.

  4. Key Issues in Nursing Theory: Developments, Challenges, and Future Directions. (United States)

    Roy, Callista

    Today, we face a situation some call the "profession at the crossroads." The problem is the development of the profession being threatened by an imbalance among philosophical, conceptual/theoretical, and empirical inquiry. The aims of this project are to (a) examine the development and contributions of theory, (b) outline the challenges we face in knowledge development, and (c) provide a structure for disciplinary knowledge that provides a unifying focus and renovates theories' place in nursing science that can direct the future of developing knowledge for practice. A personal narrative along with literature reviews. Narrative strategies included my own publications on theory, some relevant unpublished speeches, memories of meetings checked with concurrent attendees, and similar or dissimilar points of view in nursing theory textbooks. Contributions of theoretical work in the 20th century included maturing of the discipline, clarifying the theoretical focus of nursing as holistic persons with processes and patterns for environmental integration to attain health, a plurality of grand theories for articulating and testing of theories in practice and research, identification of the mutual impact of theory and education and major conferences, and contributions globally. Twenty-first century developments used all levels of theories particularly for research. Questions are raised about the evaluation of theory. Detours and dead ends for theory development involved metatheory debates and specific events. Challenges identified relate to rapid changes in society, healthcare, and science. A pathway for the future is presented in a figure with its description of the structure of nursing knowledge. The potential of this structure for developing future theory-based nursing knowledge for practice is envisioned, and strategies for creating this future are suggested.

  5. Validation of a Previously Developed Geospatial Model That Predicts the Prevalence of Listeria monocytogenes in New York State Produce Fields. (United States)

    Weller, Daniel; Shiwakoti, Suvash; Bergholz, Peter; Grohn, Yrjo; Wiedmann, Martin; Strawn, Laura K


    Technological advancements, particularly in the field of geographic information systems (GIS), have made it possible to predict the likelihood of foodborne pathogen contamination in produce production environments using geospatial models. Yet, few studies have examined the validity and robustness of such models. This study was performed to test and refine the rules associated with a previously developed geospatial model that predicts the prevalence of Listeria monocytogenes in produce farms in New York State (NYS). Produce fields for each of four enrolled produce farms were categorized into areas of high or low predicted L. monocytogenes prevalence using rules based on a field's available water storage (AWS) and its proximity to water, impervious cover, and pastures. Drag swabs (n = 1,056) were collected from plots assigned to each risk category. Logistic regression, which tested the ability of each rule to accurately predict the prevalence of L. monocytogenes, validated the rules based on water and pasture. Samples collected near water (odds ratio [OR], 3.0) and pasture (OR, 2.9) showed a significantly increased likelihood of L. monocytogenes isolation compared to that for samples collected far from water and pasture. Generalized linear mixed models identified additional land cover factors associated with an increased likelihood of L. monocytogenes isolation, such as proximity to wetlands. These findings validated a subset of previously developed rules that predict L. monocytogenes prevalence in produce production environments. This suggests that GIS and geospatial models can be used to accurately predict L. monocytogenes prevalence on farms and can be used prospectively to minimize the risk of preharvest contamination of produce.

    Domínguez-Vigo, P; Álvarez-Silvares, E; Alves-Pérez M T; Domínguez-Sánchez, J; González-González, A


    Gestational diabetes is considered a variant of diabetes mellitus as they share a common pathophysiological basis: insulin resistance in target and insufficient secretion of it by pancreatic p-cell bodies. Pregnancy is a unique physiological situation provides an opportunity to identify future risk of diabetes mellitus. To determine the long-term incidence of diabetes mellitus in women who have previously been diagnosed with gestational diabetes and identifying clinical risk factors for developing the same. nested case-control cohort study. 671 patients between 1996 and 2009 were diagnosed with gestational diabetes were selected. The incidence of diabetes mellitus was estimated and 2 subgroups were formed: Group A or cases: women who develop diabetes mellitus after diagnosis of gestational diabetes. Group B or control: random sample of 71 women with a history of gestational diabetes in the follow-up period remained normoglycemic. Both groups were studied up to 18 years postpartum. By studying Kaplan Meier survival of the influence of different gestational variables it was obtained in the later development of diabetes mellitus with time parameter and COX models for categorical variables were applied. Significant variables were studied by multivariate Cox analysis. In all analyzes the Hazard ratio was calculated with confidence intervals at 95%. The incidence of diabetes mellitus was 10.3% in patients with a history of gestational diabetes. They were identified as risk factors in the index pregnancy to later development of diabetes mellitus: greater than 35 and younger than 27 years maternal age, BMI greater than 30 kg/m2, hypertensive disorders of pregnancy, insulin therapy, poor metabolic control and more than a complicated pregnancy with gestational diabetes. Clinical factors have been identified in the pregnancy complicated by gestational diabetes that determine a higher probability of progression to diabetes mellitus in the medium and long term.

  10. Planning policy, sustainability and housebuilder practices: The move into (and out of?) the redevelopment of previously developed land. (United States)

    Karadimitriou, Nikos


    This paper explores the transformations of the housebuilding industry under the policy requirement to build on previously developed land (PDL). This requirement was a key lever in promoting the sustainable urban development agenda of UK governments from the early 1990s to 2010 and has survived albeit somewhat relaxed and permutated in the latest National Planning Policy Framework (NPPF). The paper therefore looks at the way in which the policy push towards densification and mixed use affected housebuilders' business strategy and practices and their ability to cope with the 2007 downturn of the housing market and its aftermath. It also points out the eventual feedback of some of these practices into planning policy. Following the gradual shift of British urban policy focus towards sustainability which started in the early 1990s, new configurations of actors, new skills, strategies and approaches to managing risk emerged in property development and housebuilding. There were at least two ways in which housebuilders could have responded to the requirements of developing long term mixed use high density projects on PDL. One way was to develop new products and to employ practices and combinations of practices involving phasing, a flexible approach to planning applications and innovative production methods. Alternatively, they could approach PDL development as a temporary turn of policy or view mixed use high density schemes as a niche market to be explored without drastically overhauling the business model of the entire firm. These transformations of the UK housebuilding sector were unfolding during a long period of buoyancy in the housing market which came to an end in 2007. Very little is known both about how housebuilder strategies and production practices evolved during the boom years as well as about how these firms coped with the effects of the 2007 market downturn. The paper draws on published data (company annual reports, government statistics) and primary

  18. The theory of sustainable Tourism Development

    Directory of Open Access Journals (Sweden)

    Alberta Tahiri


    Full Text Available Tourism is a phenomenon that has seen a rapid multi fold increase and growth since the middle of the twentieth century. For host communities and countries, the development of tourism has offered numerous advantages, as well as some significant challenges and difficulties. In recent decades, the awareness has been strengthened that tourism needs to be developed following the sustainable development concept. This approach eliminates or significantly decreases the negative impacts of tourism growth and sets the basis for long-term enjoyment of benefits. In the field of tourism, sustainable development translates in two important categories of considerations: conserving natural environment and resources and the biodiversity and conserving the living cultural heritage and traditions. Designing sustainable tourism development strategies should be done in cooperative efforts by the state, businesses and local communities. The strategies need to focus on maximizing the potential positive and eliminating or minimizing potential negative impacts. Impact monitoring and evaluation mechanisms need to be set up, including identification of performance indicators. When tourism growth emerges from a carefully designed and implemented strategy, tourism is documented to contribute to generating foreign exchange earnings, creating employment and income, and stimulating domestic consumption. It also brings about social and cultural development of the host communities. Researches have shown that smaller and developing countries specialized in tourism experience higher economic growth compared to countries without significant tourism industry. Contemporary economic and statistical methods ensure that the contribution of tourism in national economies can be precisely and easily measured, which in itself can be used as an indicator in assessing the impact and effects of tourism growth.

    Full Text Available This article offers a critical review of the concept of social capital, focusing on the theoretical underpinnings of the communitarian approach. It argues that this approach has a culturalist bias that omits key issues of inequality, conflict and power, making it a tool that is unlikely to contribute significantly to poverty reduction or development. As an example, it describes the adoption of the concept by the World Bank and provides a case study of rural community organization in Ecuador.

  2. Intercorporeality andaida: Developing an interaction theory of social cognition. (United States)

    Tanaka, Shogo


    The aim of this article is to develop an interaction theory (IT) of social cognition. The central issue in the field of social cognition has been theory of mind (ToM), and there has been debate regarding its nature as either theory-theory or as simulation theory. Insights from phenomenology have brought a second-person perspective based on embodied interactions into the debate, thereby forming a third position known as IT. In this article, I examine how IT can be further elaborated by drawing on two phenomenological notions-Merleau-Ponty's intercorporeality and Kimura's aida . Both of these notions emphasize the sensory-motor, perceptual, and non-conceptual aspects of social understanding and describe a process of interpersonal coordination in which embodied interaction gains autonomy as an emergent system. From this perspective, detailed and nuanced social understanding is made possible through the embodied skill of synchronizing with others.

    Riley, William T; Martin, Cesar A; Rivera, Daniel E; Hekler, Eric B; Adams, Marc A; Buman, Matthew P; Pavel, Misha; King, Abby C


    Social cognitive theory (SCT) is among the most influential theories of behavior change and has been used as the conceptual basis of health behavior interventions for smoking cessation, weight management, and other health behaviors. SCT and other behavior theories were developed primarily to explain differences between individuals, but explanatory theories of within-person behavioral variability are increasingly needed as new technologies allow for intensive longitudinal measures and interventions adapted from these inputs. These within-person explanatory theoretical applications can be modeled as dynamical systems. SCT constructs, such as reciprocal determinism, are inherently dynamical in nature, but SCT has not been modeled as a dynamical system. This paper describes the development of a dynamical system model of SCT using fluid analogies and control systems principles drawn from engineering. Simulations of this model were performed to assess if the model performed as predicted based on theory and empirical studies of SCT. This initial model generates precise and testable quantitative predictions for future intensive longitudinal research. Dynamic modeling approaches provide a rigorous method for advancing health behavior theory development and refinement and for guiding the development of more potent and efficient interventions.

  5. Observant, Nonaggressive Temperament Predicts Theory of Mind Development (United States)

    Wellman, Henry M.; Lane, Jonathan D.; LaBounty, Jennifer; Olson, Sheryl L.


    Temperament dimensions influence children’s approach to and participation in social interactive experiences which reflect and impact children’s social understandings. Therefore, temperament differences might substantially impact theory of mind development in early childhood. Using longitudinal data, we report that certain early temperament characteristics (at age 3) – lack of aggressiveness, a shy-withdrawn stance to social interaction, and social-perceptual sensitivity – predict children’s more advanced theory-of-mind understanding two years later. The findings contribute to our understanding of how theory of mind develops in the formative preschool period; they may also inform debates as to the evolutionary origins of theory of mind.

  6. The Individual Practice Development Theory: an individually focused practice development theory that helps target practice development resources. (United States)

    Melton, Jane; Forsyth, Kirsty; Freeth, Della


    Research indicates that multifaceted practice development (PD) interventions are more effective than single strategies. However, models of education in health care need to consider cost-effectiveness. This paper presents a research-based, PD theory called the Individual Practice Development Theory. It argues that programmes that use the Individual Practice Development Theory to tailor PD support to the learning needs of practitioners will result in more engagement in PD and will target PD resources efficiently. The in-depth qualitative, multi-method realistic evaluation was of a multifaceted, organization-wide PD programme in one National Health Service Mental Health and Learning Disabilities Trust. Semi-structured interviews, practice observation and documentation audit were used to gather data from occupational therapists. Results indicated that environmental contexts, particularly the support of the immediate team, and the participant's personal circumstances affected PD behaviour change. Six mechanisms acted as catalysts. These were: Building Confidence, Finding Flow, Accumulating Reward, Conferring with Others, Constructing Knowledge Know-how and Channelling Time. Four stages of PD characterized as: 'In the Hangar', 'On the Runway', 'Take-off' and 'In the Air' were identified. The research also illustrated the interconnectivity between outcome levels, contextual circumstances and activating mechanisms. The findings suggested that PD interventions need to be more individually tailored to achieve optimum learning outcomes. The identification of four discernable stages permits rapid understanding of PD support needs in order to focus PD support. With a systematic and individualized approach to PD in health care, more target PD supports can be put in place. © 2011 Blackwell Publishing Ltd.

  14. [The development of I. P. Pavlov's conditioned reflex theory]. (United States)

    Kim, O J


    This paper deals with the theory of Ivan Petrovich Pavlov (1849-1936), a Russian physiologist who presented for the first time the systematic theory of the function of the brain that controls the whole behavior of animals, i.e. higher nervous activity through experimental studies. This paper, principally based on Lectures on Conditioned Reflexes (1928), investigates the development of conditioned reflex theory from its beginning by dividing it into three periods. First, during the period from 1898 to 1906, the fundamental concept of conditioned reflex was established and the study of conditioned reflex became an independent discipline. From 1907 to 1916, the second period, Pavlov theorized on higher nervous activity on the basis of extensive data from his laboratory experiments of conditioned reflex. And Pavlov complemented conditioned reflex theory, during the third period from 1916 to 1928, and extended the boundaries of it through applications of conditioned reflex theory to psychopathology and typology. The study contributes to the understanding that conditioned reflex theory was historically developed, and not presented as a complete form from the beginning, and that Pavlov intended to study the higher nervous activity through the method of neurophysiology.

    An essential characteristic of advanced practice nurses is the use of theory in practice. Clinical nurse specialists apply theory in providing or directing patient care, in their work as consultants to staff nurses, and as leaders influencing and facilitating system change. Knowledge of technology and pharmacology has far outpaced knowledge of how to facilitate health behavior change, and new theories are needed to better understand how practitioners can facilitate health behavior change. In this article, the Integrated Theory of Health Behavior Change is described, and an example of its use as foundation to intervention development is presented. The Integrated Theory of Health Behavior Change suggests that health behavior change can be enhanced by fostering knowledge and beliefs, increasing self-regulation skills and abilities, and enhancing social facilitation. Engagement in self-management behaviors is seen as the proximal outcome influencing the long-term distal outcome of improved health status. Person-centered interventions are directed to increasing knowledge and beliefs, self-regulation skills and abilities, and social facilitation. Using a theoretical framework improves clinical nurse specialist practice by focusing assessments, directing the use of best-practice interventions, and improving patient outcomes. Using theory fosters improved communication with other disciplines and enhances the management of complex clinical conditions by providing holistic, comprehensive care.

  16. Spectrophotometric determination of uranium with arsenazo previous liquid-liquid extraction and colour development in organic medium

    International Nuclear Information System (INIS)

    Palomares Delgado, F.; Vera Palomino, J.; Petrement Eguiluz, J. C.


    The determination of uranium with arsenazo is hindered by a great number of cation which form stable complexes with the reactive and may given rise to serious interferences. By studying the optimum conditions of uranium the extraction be means of tributylphosphate solutions dissolved in methylisobuthylketone, under conditions for previous masking of the interfering cations, an organic extract was obtained containing all the uranium together with small amounts of iron. The possible interference derived from the latter element is avoided by reduction with hydroxylammoniumchlorid followed by complex formation of the Fe(II)-ortophenantroline compound in alcoholic medium.

  17. Endogenous development. Theories and policies of territorial development


    Vázquez Barquero , Antonio


    Endogenous development is an interpretation that includes different points of view which share the same theoretical and policy patterns. It is a territorial approach to development that refers to growth and capital accumulation processes of territories that have their own culture and institutions, upon which investment decisions are made. From this perspective, endogenous development policy is the local actors answer to the challenge of globalization. The paper argues that endogenous developm...

    Kačar Bahrija


    Full Text Available In this paper is a detailed analysis of the basics in the theory of economic development during the period from mid last century until today. It states the most significant theories, points out their ranges, offers a critical review regarding their treatment of development, especially regional, rural and local one. It observes those theories according to different classifications existing in scientific literature, primarily the ascend theory, stagnation theory, balanced economic growth theory; then, short-term and long-term development and growth theories; traditional and endogenous theories; economic growth stages theory emphasized after the WWII; structural changes theory; dependency theory, neo-classic counter-revolution theory and endogenous theory as a new growth theory. The analysis becomes wider with a study on development in regional economy theories and rural studies and it systematizes the classification of those theories according to regional economy academics. Distancing ourselves from any particular division as the most suitable and acceptable one, the theories are treated separately and in an historic context, in order to encircle the time framework which from modern theories, dealing with local level development difficulties, resulted. It asserts The Community-led Rural Development Theory, often referred to as the Community Development Theory, or marked as Bottom-up Partnership Approach. The analysis of development theories asserts that mixed exogenous - endogenous approach to development links the rural/local development to the globalization process mostly due to fast technology changes of the IT and communication sectors.

  14. Inflatable Antenna for CubeSat: Extension of the Previously Developed S-Band Design to the X-Band (United States)

    Babuscia, Alessandra; Choi, Thomas; Cheung, Kar-Ming; Thangavelautham, Jekan; Ravichandran, Mithun; Chandra, Aman


    The inflatable antenna for CubeSat is a 1 meter antenna reflector designed with one side reflective Mylar, another side clear Mylar with a patch antenna at the focus. The development of this technology responds to the increasing need for more capable communication systems to allow CubeSats to operate autonomously in interplanetary missions. An initial version of the antenna for the S-Band was developed and tested in both anechoic chamber and vacuum chamber. Recent developments in transceivers and amplifiers for CubeSat at X-band motivated the extension from the S-Band to the X-Band. This paper describes the process of extending the design of the antenna to the X-Band focusing on patch antenna redesign, new manufacturing challenges and initial results of experimental tests.

  15. Implications of learning theory for developing programs to decrease overeating. (United States)

    Boutelle, Kerri N; Bouton, Mark E


    Childhood obesity is associated with medical and psychological comorbidities, and interventions targeting overeating could be pragmatic and have a significant impact on weight. Calorically dense foods are easily available, variable, and tasty which allows for effective opportunities to learn to associate behaviors and cues in the environment with food through fundamental conditioning processes, resulting in measurable psychological and physiological food cue reactivity in vulnerable children. Basic research suggests that initial learning is difficult to erase, and that it is vulnerable to a number of phenomena that will allow the original learning to re-emerge after it is suppressed or replaced. These processes may help explain why it may be difficult to change food cue reactivity and overeating over the long term. Extinction theory may be used to develop effective cue-exposure treatments to decrease food cue reactivity through inhibitory learning, although these processes are complex and require an integral understanding of the theory and individual differences. Additionally, learning theory can be used to develop other interventions that may prove to be useful. Through an integration of learning theory, basic and translational research, it may be possible to develop interventions that can decrease the urges to overeat, and improve the weight status of children.

    Full Text Available Vegotesky theory is a paramount for the vocabulary development with its multidimensional approach, which has the impact on the cognitive affective contextual aspects and social interaction.Socio-cultural theory(SCT is the mental development of specific sphere human. It also concerns mediation and the different kinds of mediation tools adopted and valued by society.This paper highlighted that learning as a mediated process in social in origin and then becomes individual as a result of linguistically mediated interaction between the child and more experienced members of the society including parents, teachers, and peers. The relation of mediation of SCT and environment is to enhance vocabulary development in teaching EFL students. It also helps EFL  students to use the target language in their daily life .With the help of this theory, the students can master vocabulary and improve their language.This theory focuses on the interaction with the students and shows the social environment. It links the learners with the trainer, if a child/student gets a guidance in an appropriate way he/she can learn more and can enhance his/her capacity of learning.This study tried to look at the influence of SCT on learning and teaching vocabulary. Consequently, This study recommends the use of the SCT while teaching EFL Libyan learners to enhance English language vocabulary.

  20. The reliability of the Associate Platinum digital foot scanner in measuring previously developed footprint characteristics: a technical note. (United States)

    Papuga, M Owen; Burke, Jeanmarie R


    An ink pad and paper, pressure-sensitive platforms, and photography have previously been used to collect footprint data used in clinical assessment. Digital scanners have been widely used more recently to collect such data. The purpose of this study was to evaluate the intra- and interrater reliability of a flatbed digital image scanning technology to capture footprint data. This study used a repeated-measures design on 32 (16 male 16 female) healthy subjects. The following measured indices of footprint were recorded from 2-dimensional images of the plantar surface of the foot recorded with an Associate Platinum (Foot Levelers Inc, Roanoke, VA) digital foot scanner: Staheli index, Chippaux-Smirak index, arch angle, and arch index. Intraclass correlation coefficient (ICC) values were calculated to evaluate intrarater, interday, and interclinician reliability. The ICC values for intrarater reliability were greater than or equal to .817, indicating an excellent level of reproducibility in assessing the collected images. Analyses of variance revealed that there were no significant differences between raters for each index (P > .05). The ICC values also indicated excellent reliability (.881-.971) between days and clinicians in all but one of the indices of footprint, arch angle (.689), with good reliability between clinicians. The full-factorial analysis of variance model did not reveal any interaction effects (P > .05), which indicated that indices of footprint were not changing across days and clinicians. Scanning technology used in this study demonstrated good intra- and interrater reliability measurements of footprint indices, as demonstrated by high ICC values.

  1. Development theory and changes in the international system

    Directory of Open Access Journals (Sweden)

    José Antonio Alonso


    Full Text Available Development theory has undergone several changes over the last two decades. However, the international reality has changed more profoundly. The increased heterogeneity of the developing world, the diverse experience of economic success among some developing countries, the new geography of global poverty, the increased multipolarity of the international system and the wider spheres of international public assets are just some of these changes. Thus, it is necessary to think again about the development process and the strategies that are required to promote economic and social change. This article represents an attempt to contribute to that reflection.

  2. Hemoglobin-Based Oxygen Carrier (HBOC) Development in Trauma: Previous Regulatory Challenges, Lessons Learned, and a Path Forward. (United States)

    Keipert, Peter E


    Historically, hemoglobin-based oxygen carriers (HBOCs) were being developed as "blood substitutes," despite their transient circulatory half-life (~ 24 h) vs. transfused red blood cells (RBCs). More recently, HBOC commercial development focused on "oxygen therapeutic" indications to provide a temporary oxygenation bridge until medical or surgical interventions (including RBC transfusion, if required) can be initiated. This included the early trauma trials with HemAssist ® (BAXTER), Hemopure ® (BIOPURE) and PolyHeme ® (NORTHFIELD) for resuscitating hypotensive shock. These trials all failed due to safety concerns (e.g., cardiac events, mortality) and certain protocol design limitations. In 2008 the Food and Drug Administration (FDA) put all HBOC trials in the US on clinical hold due to the unfavorable benefit:risk profile demonstrated by various HBOCs in different clinical studies in a meta-analysis published by Natanson et al. (2008). During standard resuscitation in trauma, organ dysfunction and failure can occur due to ischemia in critical tissues, which can be detected by the degree of lactic acidosis. SANGART'S Phase 2 trauma program with MP4OX therefore added lactate >5 mmol/L as an inclusion criterion to enroll patients who had lost sufficient blood to cause a tissue oxygen debt. This was key to the successful conduct of their Phase 2 program (ex-US, from 2009 to 2012) to evaluate MP4OX as an adjunct to standard fluid resuscitation and transfusion of RBCs. In 2013, SANGART shared their Phase 2b results with the FDA, and succeeded in getting the FDA to agree that a planned Phase 2c higher dose comparison study of MP4OX in trauma could include clinical sites in the US. Unfortunately, SANGART failed to secure new funding and was forced to terminate development and operations in Dec 2013, even though a regulatory path forward with FDA approval to proceed in trauma had been achieved.

  3. Developing interprofessional education online: An ecological systems theory analysis. (United States)

    Bluteau, Patricia; Clouder, Lynn; Cureton, Debra


    This article relates the findings of a discourse analysis of an online asynchronous interprofessional learning initiative involving two UK universities. The impact of the initiative is traced over three intensive periods of online interaction, each of several-weeks duration occurring over a three-year period, through an analysis of a random sample of discussion forum threads. The corpus of rich data drawn from the forums is interpreted using ecological systems theory, which highlights the complexity of interaction of individual, social and cultural elements. Ecological systems theory adopts a life course approach to understand how development occurs through processes of progressively more complex reciprocal interaction between people and their environment. This lens provides a novel approach for analysis and interpretation of findings with respect to the impact of pre-registration interprofessional education and the interaction between the individual and their social and cultural contexts as they progress through 3/4 years of their programmes. Development is mapped over time (the chronosystem) to highlight the complexity of interaction across microsystems (individual), mesosystems (curriculum and institutional/care settings), exosystems (community/wider local context), and macrosystems (national context and culture). This article illustrates the intricacies of students' interprofessional development over time and the interactive effects of social ecological components in terms of professional knowledge and understanding, wider appreciation of health and social care culture and identity work. The implications for contemporary pre-registration interprofessional education and the usefulness and applicability of ecological systems theory for future research and development are considered.

  5. The roots and development of constructivist grounded theory. (United States)

    Higginbottom, Gina; Lauridsen, Erica I


    To deconstruct how Charmaz's constructivist grounded theory (CGT) evolved from the original ideas of Glaser and Strauss, and to explore how CGT is similar to and different from the original grounded theory (GT). The origins of GT date to 1967 with Glaser and Strauss's study of the treatment of dying individuals, applying an inductive method allowing for the development of theory without the guidance of a preconceived theory. CGT moves away from the positivism of the Glaserian and Straussian GT schools, approaching GT through a constructivist lens that addresses how realities are made. This article does not involve the collection and analysis of primary data; instead, academic literature written by leaders in the field of GT was reviewed to generate the ideas presented. Comprehensive literature review drawing on the 'integrative review' principles. When selecting a GT approach, the possibility of a congruence between the chosen methodology and the worldviews of the researcher's discipline and own outlook should be considered. The differences among the various schools of GT lie in their overarching goals and their perspectives of the nature of reality. Considering the alignment between the constructivist worldview and the field of nursing, CGT offers a valuable methodology for researchers in this area.

  6. [Development of delusion in view of Luhmann's systems theory]. (United States)

    Maier, T


    The systems theory of Niklas Luhmann declares itself as a universal theory and therefore claims applicability to any social and psychic phenomenon.In spite of its high complexity, to many it seems too vague and nonspecific. The possible usefulness of this theory should be demonstrated on the example of the development of delusion, still a mysterious and unexplained phenomenon. Within the framework of Luhmann's systems theory, delusion can be considered a communication disorder and therefore a phenomenon within the social system. Both the autopoietic systems society and psyche are based on and processed by meaning but cannot communicate directly, and they are mutually nontransparent and unpredictable. Due to this fact, the interface between the two systems is a potential source of disturbances. Luhmann defines the distinction of information, message, and understanding as the crucial element to connect the social system with the psychic one. If the psychic system fails to recognize the message of an information correctly or is unable to negotiate between understanding and misunderstanding messages, it detaches itself from the social system to which it is normally closely connected. This detachment releases the possibility of unhindered autistic fulfillment of desires and uncontrolled fear. Due to the meaning-based autopoiesis of the psychic system,these released thoughts and emotions still appear in meaningfully condensed form as delusions.

    Traditional Chinese medicine (TCM) prescription is the main therapies for disease prevention and treatment in Chinese medicine. Following the guidance of the theory of TCM and developing drug by composing prescriptions of TCM materials and pieces, it is a traditional application mode of TCM, and still widely used in clinic. TCM prescription has theoretical advantages and rich clinical application experience in dealing with multi-factor complex diseases, but scientific research is relatively weak. The lack of scientific cognition of the effective substances and mechanism of Chinese medicine leads to insufficient understanding of the efficacy regularity, which affects the stability of effect and hinders the improvement of quality of Chinese medicinal products. Component-based Chinese medicine (CCM) is an innovation based on inheritance, which breaks through the tradition of experience-based prescription and realize the transformation of compatibility from herbal pieces to components. CCM is an important achievement during the research process of modernization of Chinese medicine. Under the support of three national "973" projects, in order to reveal the scientific connotation of the prescription compatibility theory and develop innovative Chinese drugs, we have launched theoretical innovation and technological innovation around the "two relatively clear", and opened up the research field of CCM. CCM is an innovation based on inheritance, breaking through the tradition of experience based prescription, and realizing the transformation from compatibility of herbal pieces to component compatibility, which is an important achievement of the modernization of traditional Chinese medicine. In the past more than 10 years, with the deepening of research and the expansion of application, the theory and methods of CCM and efficacy-oriented compatibility have been continuously improved. The value of CCM is not only in developing new drug, more important is to build a

    The PM leadership theory developed by Misumi, et al., basically identifies leadership behavior in terms of two dimensions, i.e., P(Performance) behavior and M(Maintenance) behavior, and divides it into four types, PM, M, P and pm, depending on the degree to which each of them performs its behavior. Thus, it has been verified that the differences between these types have an effect on various variables, such as subordinates' morale, productivity and reduced incidence of accidents. To be more concrete, it has been consistently found as a result of a number of studies that what brings about the most desirable results in the eyes of organizations is the PM type, followed by M, P and pm in the order mentioned. The most basic premise for the PM theory is that leadership lies not in the leader's personal traits but in his behavior. Consequently, any leadership type is not 'carved in stone', and it can change according to the leader's behavior. From this, it follows that leadership can be improved and upgraded. As the PM leadership theory has become well-established, the development research and implementation of leadership training aimed at improving and upgrading leadership was launched. In this paper, the leadership training that is now in progress will be discussed, with particular reference to its purpose, current status of its overall progress and its typical training schedule. That done, the history of development of the leadership training will be reviewed, and at the same time, its effects will be examined on the basis of some empirical data. Also some proposals will be presented concerning the relationship between organizational development and training as well as some problems to be addressed in the future. (author)

  15. To the Issue of the Practice Theory Development

    Directory of Open Access Journals (Sweden)

    N. K. Tchapayev


    Full Text Available The paper deals with the theoretical analysis of practical training as one of the two main forms of vocational training. Industrial practice is regarded as poly-systematic, alternative existence of students entering the adults’ world, the means for developing students’ functional responsibility and subjective world outlook, etc. The paper overcomes the existing utilitarian one-sided approach to the place and value of practice, its impact on the specialist’s professional development and opportunities for professional growth being explored. Regarding the practical training as psycho-pedagogical and educational phenomenon, the authors developed the theoretical and methodological bases for its designing and conducting in vocational schools. The research conclu- sions contain some heuristic innovative potential facilitating both the foundation of independent theory of practical training and organization of practice oriented training in vocational schools. 

  16. Multiple-scattering theory. New developments and applications

    Energy Technology Data Exchange (ETDEWEB)

    Ernst, Arthur


    Multiple-scattering theory (MST) is a very efficient technique for calculating the electronic properties of an assembly of atoms. It provides explicitly the Green function, which can be used in many applications such as magnetism, transport and spectroscopy. This work gives an overview on recent developments of multiple-scattering theory. One of the important innovations is the multiple scattering implementation of the self-interaction correction approach, which enables realistic electronic structure calculations of systems with localized electrons. Combined with the coherent potential approximation (CPA), this method can be applied for studying the electronic structure of alloys and as well as pseudo-alloys representing charge and spin disorder. This formalism is extended to finite temperatures which allows to investigate phase transitions and thermal fluctuations in correlated materials. Another novel development is the implementation of the self-consistent non-local CPA approach, which takes into account charge correlations around the CPA average and chemical short range order. This formalism is generalized to the relativistic treatment of magnetically ordered systems. Furthermore, several improvements are implemented to optimize the computational performance and to increase the accuracy of the KKR Green function method. The versatility of the approach is illustrated in numerous applications. (orig.)

  18. Development of depletion perturbation theory for a reactor nodal code

    Energy Technology Data Exchange (ETDEWEB)

    Bowman, S.M.


    A generalized depletion perturbation (DPT) theory formulation for light water reactor (LWR) depletion problems is developed and implemented into the three-dimensional LWR nodal code SIMULATE. This development applies the principles of the original derivation by M.L. Williams to the nodal equations solved by SIMULATE. The present formulation is first described in detail, and the nodal coupling methodology in SIMULATE is used to determine partial derivatives of the coupling coefficients. The modifications to the original code and the new DPT options available to the user are discussed. Finally, the accuracy and the applicability of the new DPT capability to LWR design analysis are examined for several LWR depletion test cases. The cases range from simple static cases to a realistic PWR model for an entire fuel cycle. Responses of interest included K/sub eff/, nodal peaking, and peak nodal exposure. The nonlinear behavior of responses with respect to perturbations of the various types of cross sections was also investigated. The time-dependence of the sensitivity coefficients for different responses was examined and compared. Comparison of DPT results for these examples to direct calculations reveals the limited applicability of depletion perturbation theory to LWR design calculations at the present. The reasons for these restrictions are discussed, and several methods which might improve the computational accuracy of DPT are proposed for future research.

  19. Theories of International Economic Development (Case Study: Economic Development in Kosovo

    MSc. Bardhok Bashota


    Full Text Available Karl Popper rightly says that “real starting point for each research is set based on assumptions of reality, not only based on the real facts”. The text below was prepared In accordance with this logic, where the Theories of International Development are treated especially focusing on International Economic Development. Therefore, theoretical reflections present assumption side, and study of many empirically measured data will correspond with real facts, because with ought these facts assumption would be useless. Technically this writing consists of two parts: in the first part are elaborated all theoretical and practical characteristics of overall international development, while in a second part as a case study will be Economic Development i Kosovo. From methodological point of view this is a comparative study and based on statistical data, while problem treating approach is critical and explanatory. As it will be understood later, development theories have been decisively influenced by economic thinking, and the focus on this dimension responds best to the nature of the term development. On the other hand the fact of unfolding economical development will reflect interference and the nature of it’s inter politics. Today economic development becomes a worldwide goal, having a considerable place in most of the literature with economic content. Also, here are presented as well examples from different practices that reflect economic development in different periods and places. Here is presented international economic development starting with a brief description of a genealogy of this development and ways of economic development back that time. It is of a special importance elaboration through theoretical approach on the creation of capital and economic development, as  mercantilist theory, classic and neo classic theory, than capitalization and Socialism-Marxism. To better understand the nature of economic development, the focus falls on

  20. Development and verification of multicycle depletion perturbation theory

    International Nuclear Information System (INIS)

    White, J.R.; Burns, T.J.


    Recently, Williams has developed a coupled neutron/nuclide depletion perturbation theory (DPT) applicable to multidimensional and multigroup reactor analysis problems. This theoretical framework has been verified using the newly developed DEPTH module within the context of the VENTURE modular code system. The accuracy and usefulness of this alternate calculational method for burnup analyses has been demonstrated for a variety of final-time response functionals. However, these examples were restricted to single-cycle depletion analyses due to the theoretical assumption that the nuclide density field was continuous in time. Clearly, in multicycle problems, the nuclide concentrations must vary discontinuously with time to model refueling and shuffling operations or discrete control rod movements. Thus, the purpose of this work is to generalize the original DPT framework to include nuclide discontinuities and to verify that this generalization can be employed in realistic multicycle applications

  1. Research on Operating Procedure Development in View of RCM Theory

    International Nuclear Information System (INIS)

    Shi, J.


    The operation of NPPs (nuclear power plants) is closely related to SSCs (Structure, System and Component) function implementations and failure recoveries, and strictly follows operating procedure. The philosophy of RCM (Reliability Centered Maintenance) which is a widely-used systematic engineering approach in industry focusing on likewise facility functions and effectiveness of maintenance is accepted in relative analysis of NPPs operation in this paper. Based on the theory of RCM, the paper will discuss general logic of operating procedure development and framework optimization as well combining NPPs engineering design. Since the quality of operating procedures has a significant impact on the safe and reliable operation of NPPs, the paper provides a proposed operating procedure development logic diagramme for reference for the procedure optimization task ahead.

  2. What can psychoanalysts learn from the development of literary theory? (United States)

    Chessick, Richard D


    It is no accident that literary theorists and academicians have become very interested in psychoanalysis. There is a remarkable parallel between the development of literary theory from its origins to the present day and the development of psychoanalysis from the time of Freud to now. The same concerns that have troubled critics of art and literature about how to go about evaluating an artwork are the ones most controversial today in the field of psychoanalysis. The questions, for example, of whether beauty resides in the work of art or in the mind of the audience and its parallel in psychoanalysis, whether the material produced by the patient is essentially from the patient or the product of an interaction between patient and analyst, or even whether it is ever possible to interpret any patient material or artwork all the way down to some basic qualities remain unanswered and polemical today.

    Shvindina Hanna Olexandrivna


    Full Text Available The research on how organizational and social changes are shaped and explained is done in the paper. Traditional assumptions and new theories of social development and organizational development were united into classification offered by author through the dichotomy principle of classification. This article combines the existing classification principles and presents new ones. The contribution of the author is the assumption that the characteristics of development theories can be distinguished by the following contrast groups: Evolution – Revolution, Cycle – Wave, Equilibrium – Punctuated Equilibrium, Standard – Paradox. Meanwhile the first three groups are presented and analyzed, the fourth group is left as hypothesis for the next research.

  4. How Stock Markets Development Affect Endogenous Growth Theory

    Directory of Open Access Journals (Sweden)

    Najeb Masoud


    Full Text Available This paper can bedescribed as a significant exploratory study that will provide a significantcontribution to knowledge to consider crucial issues which need to be barriersto understanding or a temptation/ requirement to judge some practices as‘better’ than others for stock market development effective approach andimplement successful stock market performance and economic growth. Recentanalysis of the link between financial development and growth, gained frominsights acquired as a result of using the technique of endogenous growthmodels, has illustrated that growth without exogenous technical progress andthat growth rates could be related to technology, income distribution andinstitutional arrangements. This provides the theoretical background thatempirical studies have lacked; illustrating that financial intermediationaffects the level of economic growth. Resulting models have provided newimpetus to empirical research of the effects of financial development. Thebirth of the new endogenous growth theory has facilitated the development ofimproved growth models where the long-term rate could be affected by a numberof elements. These included technology, education and health policies in theprocess of economic development, capital accumulation, government policies andinstitutional activities in the role of financial development in economicgrowth.

  5. Integrating mental health and social development in theory and practice. (United States)

    Plagerson, Sophie


    In many low and middle income countries, attention to mental illness remains compartmentalized and consigned as a matter for specialist policy. Despite great advances in global mental health, mental health policy and practice dovetail only to a limited degree with social development efforts. They often lag behind broader approaches to health and development. This gap ignores the small but growing evidence that social development unavoidably impacts the mental health of those affected, and that this influence can be both positive and negative. This article examines the theoretical and practical challenges that need to be overcome for a more effective integration of social development and mental health policy. From a theoretical perspective, this article demonstrates compatibility between social development and mental health paradigms. In particular, the capability approach is shown to provide a strong framework for integrating mental health and development. Yet, capability-oriented critiques on 'happiness' have recently been applied to mental health with potentially detrimental outcomes. With regard to policy and practice, horizontal and vertical integration strategies are suggested. Horizontal strategies require stronger devolution of mental health care to the primary care level, more unified messages regarding mental health care provision and the gradual expansion of mental health packages of care. Vertical integration refers to the alignment of mental health with related policy domains (particularly the social, economic and political domains). Evidence from mental health research reinforces aspects of social development theory in a way that can have tangible implications on practice. First, it encourages a focus on avoiding exclusion of those affected by or at risk of mental illness. Secondly, it underscores the importance of the process of implementation as an integral component of successful policies. Finally, by retaining a focus on the individual, it seeks to

  13. Leadership theory: implications for developing dental surgeons in primary care? (United States)

    Willcocks, S


    The development of leadership in healthcare has been seen as important in recent years, particularly at the clinical level. There have been various specific initiatives focusing on the development of leadership for doctors, nurses and other health care professions: for example, a leadership competency framework for doctors, the LEO programme and the RCN clinical leadership programme for nurses. The NHS has set up a Leadership Council to coordinate further developments. However, there has not been the same focus in dentistry, although the recent review of NHS dental services (Steele review) has proposed a need for leadership initiatives in NHS dentistry as a medium-term action. Central to this will be a need to focus on the leadership role for dental surgeons. Leadership is all the more important in dentistry, given the change of government and the policy of retrenchment, major public sector reform, the emergence of new organisations such as new commissioning consortia, possible changes to the dental contract, new ways of working, and changes to the profession such as the requirements for the revalidation of dental surgeons. The question is: which leadership theory or approach is best for dental surgeons working in primary care? This paper builds on earlier work exploring this question in relation to doctors generally, and GPs, in particular, and planned work on nurses. It will seek to address this question in relation to dental surgeons working in primary care.

  14. Eye growth and myopia development: Unifying theory and Matlab model. (United States)

    Hung, George K; Mahadas, Kausalendra; Mohammad, Faisal


    The aim of this article is to present an updated unifying theory of the mechanisms underlying eye growth and myopia development. A series of model simulation programs were developed to illustrate the mechanism of eye growth regulation and myopia development. Two fundamental processes are presumed to govern the relationship between physiological optics and eye growth: genetically pre-programmed signaling and blur feedback. Cornea/lens is considered to have only a genetically pre-programmed component, whereas eye growth is considered to have both a genetically pre-programmed and a blur feedback component. Moreover, based on the Incremental Retinal-Defocus Theory (IRDT), the rate of change of blur size provides the direction for blur-driven regulation. The various factors affecting eye growth are shown in 5 simulations: (1 - unregulated eye growth): blur feedback is rendered ineffective, as in the case of form deprivation, so there is only genetically pre-programmed eye growth, generally resulting in myopia; (2 - regulated eye growth): blur feedback regulation demonstrates the emmetropization process, with abnormally excessive or reduced eye growth leading to myopia and hyperopia, respectively; (3 - repeated near-far viewing): simulation of large-to-small change in blur size as seen in the accommodative stimulus/response function, and via IRDT as well as nearwork-induced transient myopia (NITM), leading to the development of myopia; (4 - neurochemical bulk flow and diffusion): release of dopamine from the inner plexiform layer of the retina, and the subsequent diffusion and relay of neurochemical cascade show that a decrease in dopamine results in a reduction of proteoglycan synthesis rate, which leads to myopia; (5 - Simulink model): model of genetically pre-programmed signaling and blur feedback components that allows for different input functions to simulate experimental manipulations that result in hyperopia, emmetropia, and myopia. These model simulation programs

    Directory of Open Access Journals (Sweden)

    Chuprikova N.I.,


    Full Text Available The position about the internal connection between the cultural-historical theory of development of higher mental functions of L.S. Vygotsky and two prominent theories of the 20th century is substatianted. Firstly, this is the theory of conditioned reflex of I.P. Pavlov, including the idea of significant qualitative difference between human higher nervous activity and human behaviour and those of animals, due to the presence of the second signal system as a “grand speech signal” in humans. Second, this is the differential theory of development by H. Werner, which fits a number of key ideas of L.S. Vygotsky about the development of speech function and the role of the word in the psychological development of a child.

  17. Grounded theory in medical laboratory science expert practice development. (United States)

    Leibach, Elizabeth Kenimer


    Grounded theory and methods related to expert practice development in medical laboratory science were described using data from a large national survey of medical laboratory scientists (MLS) overlaid on findings from analysis of expert practice domains reported in nursing literature. An extensive focus group/expert review iterative process followed by a survey of MLS practitioners produced 25 critical thinking (CT) behaviors important in expert practice. Factor analysis was applied to discern common threads or themes linking the CT behaviors. The 25 important CT behaviors were reduced to a 7-factor structure representing constructs underlying the individual, observable CT behaviors. This 7-factor structure in MLS was compared to the 7 practice domains identified in expert nursing practice. The comparison yielded commonality between MLS and nursing in CT behaviors observed in the 7 expert practice domains of both professions: professional techniques, caring communication, growing professionally, setting priorities, practicing with judgment, anticipating/revising, and creating unique meaning. Emergent grounded theory is that (1) critical thinking is a metaprocess that facilitates learning by interlinking the more basic processes associated with different learning orientations: cognitivist, behaviorist, humanist (affective), and situated/contextual learning, (2) CT behaviors are observable events following from the CT metaprocess, and (3) observations of CT behaviors increase as practice advances from novice to expert. Identification and definition of CT behaviors, i.e., practice competencies, along the continuum of novice to expert can serve as the foundation for MLS curriculum and instructional design as well as measurement and evaluation in both formal and continuing education settings.

  18. Propositions toward the development of a psychological theory of thought

    Directory of Open Access Journals (Sweden)

    Shadrikov, Vladimir D.


    Full Text Available Thought is considered a psychological concept associated with an individual’s mental ex- istence. It is apparent that a great deal of research has been focused on thought as an area of study. however, there is no psychological theory of thought which provides an expla- nation for its nature and structural organization. So far, researchers have mainly looked at the ways this concept is expressed, rather than investigating what it actually is. In this study, however, based on studies of the functions of the psyche, mental processes, and the neurophysiological bases of mental activity, thought is identified as a need-emotion- intentional substance existing in the human being’s inner world. In keeping with this understanding of thought, the hypothesis that thought generation is caused by desire and experience (feeling and emotion is put forward. An individual’s thought is linked to his behavior or motivation for activity, and is followed by an emotional experience. The process of thought generation is regarded through the mechanism of behavioral motiva- tion. The primary purpose of this mechanism is to define the qualities of the external objects that serve for need satisfaction and functionality in individuals. The ability to generate thoughts is a feature of thinking related to an individual’s mental ability or frame of mind. From this standpoint, a person’s mentality is considered to be the capacity of the individual to generate thoughts and work through thoughts. It is shown that the abil- ity to generate thoughts and establish relationships within a stream of consciousness is characteristic of human intelligence. Some basic propositions toward a development of a psychological theory of thought are introduced.

  19. Development of affective theory of mind across adolescence: disentangling the role of executive functions. (United States)

    Vetter, Nora C; Altgassen, Mareike; Phillips, Louise; Mahy, Caitlin E V; Kliegel, Matthias


    Theory of mind, the ability to understand mental states, involves inferences about others' cognitive (cognitive theory of mind) and emotional (affective theory of mind) mental states. The current study explored the role of executive functions in developing affective theory of mind across adolescence. Affective theory of mind and three subcomponents of executive functions (inhibition, updating, and shifting) were measured. Affective theory of mind was positively related to age, and all three executive functions. Specifically, inhibition explained the largest amount of variance in age-related differences in affective theory of mind.

    Full Text Available In this essay, we intend to review the theory of the FDI, since its origins to the present days, focusing on its corner stones. We present the FDI theory through the lens of the strategic management and try to bring to the forefront the main contributions to this framework. At the same time, we underline the scholars’ frequent return to the “springs” of the FDI theory, either those generated by Hymer or the internalization theory or the OLI paradigm, in order to consolidate the theoretical FDI construction.

  1. Concept analysis and the building blocks of theory: misconceptions regarding theory development. (United States)

    Bergdahl, Elisabeth; Berterö, Carina M


    The purpose of this article is to discuss the attempts to justify concepts analysis as a way to construct theory - a notion often advocated in nursing. The notion that concepts are the building blocks or threads from which theory is constructed is often repeated. It can be found in many articles and well-known textbooks. However, this notion is seldom explained or defended. The notion of concepts as building blocks has also been questioned by several authors. However, most of these authors seem to agree to some degree that concepts are essential components from which theory is built. Discussion paper. Literature was reviewed to synthesize and debate current knowledge. Our point is that theory is not built by concepts analysis or clarification and we will show that this notion has its basis in some serious misunderstandings. We argue that concept analysis is not a part of sound scientific method and should be abandoned. The current methods of concept analysis in nursing have no foundation in philosophy of science or in language philosophy. The type of concept analysis performed in nursing is not a way to 'construct' theory. Rather, theories are formed by creative endeavour to propose a solution to a scientific and/or practical problem. The bottom line is that the current style and form of concept analysis in nursing should be abandoned in favour of methods in line with modern theory of science. © 2016 John Wiley & Sons Ltd.

    To analyze neoplastic and hamartomatous variants of ameloblastic fibromas (AFs). Analysis of 172 cases (162 previously reported, 10 new). AF emerged as a lesion primarily of children and adolescents (mean age, 14.9 years), with about 80% diagnosed when odontogenesis is completed (age, 22 years are considered true neoplasms, while those in younger patients may be either true neoplasms or odontomas in early stages of development. Although the histopathology of hamartomatous and neoplastic variants of AF are indistinguishable, clinical and radiologic features can be of some help to distinguish between them. Asymptomatic small unilocular lesions with no or minimal bone expansion in young individuals are likely to be developing odontomas, and large, expansile lesions with extensive bone destruction are neoplasms.

  10. Evolution and development: some insights from evolutionary theory

    Directory of Open Access Journals (Sweden)



    Full Text Available Developmental biology and evolutionary biology are both mature integrative disciplines which started in the 19th century and then followed parallel and independent scientific pathways. Recently, a genetical component has stepped into both disciplines (developmental genetics and evolutionary genetics pointing out the need for future convergent maturation. Indeed, the Evo-Devo approach is becoming popular among developmental biologists, based on the facts that distant groups share a common ancestry, that precise phylogenies can be worked out and that homologous genes often play similar roles during the development of very different organisms. In this essay, I try to show that the real future of Evo-Devo thinking is still broader. The evolutionary theory is a set of diverse concepts which can and should be used in any biological field. Evolutionary thinking trains to ask « why » questions and to provide logical and plausible answers. It can shed some light on a diversity of general problems such as how to distinguish homologies from analogies, the costs and benefits of multicellularity, the origin of novel structures (e.g. the head, or the evolution of sexual reproduction. In the next decade, we may expect a progressive convergence between developmental genetics and quantitative genetics.

  11. Theory-inspired development of organic electro-optic materials

    International Nuclear Information System (INIS)

    Dalton, Larry R.


    Real-time, time-dependent density functional theory (RTTDDFT) and pseudo-atomistic Monte Carlo-molecular dynamics (PAMCMD) calculations have been used in a correlated manner to achieve quantitative definition of structure/function relationships necessary for the optimization of electro-optic activity in organic materials. Utilizing theoretical guidance, electro-optic coefficients (at telecommunication wavelengths) have been increased to 500 pm/V while keeping optical loss to less than 2 dB/cm. RTTDDFT affords the advantage of permitting explicit treatment of time-dependent electric fields, both applied fields and internal fields. This modification has permitted the quantitative simulation of the variation of linear and nonlinear optical properties of chromophores and the electro-optic activity of materials with optical frequency and dielectric permittivity. PAMCMD statistical mechanical calculations have proven an effective means of treating the full range of spatially-anisotropic intermolecular electrostatic interactions that play critical roles in defining the degree of noncentrosymmetric order that is achieved by electric field poling of organic electro-optic materials near their glass transition temperatures. New techniques have been developed for the experimental characterization of poling-induced acentric order including a modification of variable angle polarization absorption spectroscopy (VAPAS) permitting a meaningful correlation of theoretical and experimental data related to poling-induced order for a variety of complex organic electro-optic materials.

  12. Interpreting "Personality" Taxonomies: Why Previous Models Cannot Capture Individual-Specific Experiencing, Behaviour, Functioning and Development. Major Taxonomic Tasks Still Lay Ahead. (United States)

    Uher, Jana


    As science seeks to make generalisations, a science of individual peculiarities encounters intricate challenges. This article explores these challenges by applying the Transdisciplinary Philosophy-of-Science Paradigm for Research on Individuals (TPS-Paradigm) and by exploring taxonomic "personality" research as an example. Analyses of researchers' interpretations of the taxonomic "personality" models, constructs and data that have been generated in the field reveal widespread erroneous assumptions about the abilities of previous methodologies to appropriately represent individual-specificity in the targeted phenomena. These assumptions, rooted in everyday thinking, fail to consider that individual-specificity and others' minds cannot be directly perceived, that abstract descriptions cannot serve as causal explanations, that between-individual structures cannot be isomorphic to within-individual structures, and that knowledge of compositional structures cannot explain the process structures of their functioning and development. These erroneous assumptions and serious methodological deficiencies in widely used standardised questionnaires have effectively prevented psychologists from establishing taxonomies that can comprehensively model individual-specificity in most of the kinds of phenomena explored as "personality", especially in experiencing and behaviour and in individuals' functioning and development. Contrary to previous assumptions, it is not universal models but rather different kinds of taxonomic models that are required for each of the different kinds of phenomena, variations and structures that are commonly conceived of as "personality". Consequently, to comprehensively explore individual-specificity, researchers have to apply a portfolio of complementary methodologies and develop different kinds of taxonomies, most of which have yet to be developed. Closing, the article derives some meta-desiderata for future research on individuals' "personality".

  13. Non-linearities in Theory-of-Mind Development (United States)

    Blijd-Hoogewys, Els M. A.; van Geert, Paul L. C.


    Research on Theory-of-Mind (ToM) has mainly focused on ages of core ToM development. This article follows a quantitative approach focusing on the level of ToM understanding on a measurement scale, the ToM Storybooks, in 324 typically developing children between 3 and 11 years of age. It deals with the eventual occurrence of developmental non-linearities in ToM functioning, using smoothing techniques, dynamic growth model building and additional indicators, namely moving skewness, moving growth rate changes and moving variability. The ToM sum-scores showed an overall developmental trend that leveled off toward the age of 10 years. Within this overall trend two non-linearities in the group-based change pattern were found: a plateau at the age of around 56 months and a dip at the age of 72–78 months. These temporary regressions in ToM sum-score were accompanied by a decrease in growth rate and variability, and a change in skewness of the ToM data, all suggesting a developmental shift in ToM understanding. The temporary decreases also occurred in the different ToM sub-scores and most clearly so in the core ToM component of beliefs. It was also found that girls had an earlier growth spurt than boys and that the underlying developmental path was more salient in girls than in boys. The consequences of these findings are discussed from various theoretical points of view, with an emphasis on a dynamic systems interpretation of the underlying developmental paths. PMID:28101065

  15. Shielding Flowers Developing under Stress: Translating Theory to Field Application

    Directory of Open Access Journals (Sweden)

    Noam Chayut


    Full Text Available Developing reproductive organs within a flower are sensitive to environmental stress. A higher incidence of environmental stress during this stage of a crop plants’ developmental cycle will lead to major breaches in food security. Clearly, we need to understand this sensitivity and try and overcome it, by agricultural practices and/or the breeding of more tolerant cultivars. Although passion fruit vines initiate flowers all year round, flower primordia abort during warm summers. This restricts the season of fruit production in regions with warm summers. Previously, using controlled chambers, stages in flower development that are sensitive to heat were identified. Based on genetic analysis and physiological experiments in controlled environments, gibberellin activity appeared to be a possible point of horticultural intervention. Here, we aimed to shield flowers of a commercial cultivar from end of summer conditions, thus allowing fruit production in new seasons. We conducted experiments over three years in different settings, and our findings consistently show that a single application of an inhibitor of gibberellin biosynthesis to vines in mid-August can cause precocious flowering of ~2–4 weeks, leading to earlier fruit production of ~1 month. In this case, knowledge obtained on phenology, environmental constraints and genetic variation, allowed us to reach a practical solution.

  16. [Psychoanalysis and epistemology: mental development and formulation of theories]. (United States)

    Zysman, Samuel


    This paper aims at studying from a psychoanalytical perspective the relationship between the acquisition of knowledge, the formulation of theories based on the generalization of such knowledge, and, what we consider to be an antecedent, the infantile sexual theories (IST). Psychoanalysis is also a psychology of normal psychic processes, among them creative activity which includes scientific thought. This is of interest to psychoanalysts and to epistemologists and paves the way to necessary interdisciplinary endeavors.

  1. Introduction of the transtheoretical model and organisational development theory in weight management: A narrative review. (United States)

    Wu, Ya-Ke; Chu, Nain-Feng


    Overweight and obesity are serious public health and medical problems among children and adults worldwide. Behavioural change has been demonstrably contributory to weight management programs. Behavioural change-based weight loss programs require a theoretical framework. We will review the transtheoretical model and the organisational development theory in weight management. The transtheoretical model is a behaviour theory of individual level frequently used for weight management programs. The organisational development theory is a more complicated behaviour theory that applies to behavioural change on the system level. Both of these two theories have their respective strengths and weaknesses. In this manuscript, we try to introduce the transtheoretical model and the organisational development theory in the context of weight loss programs among population that are overweight or obese. Ultimately, we wish to present a new framework/strategy of weight management by integrating these two theories together. Copyright © 2015 Asian Oceanian Association for the Study of Obesity.

  2. Recent developments in the theory of critical phenomena

    International Nuclear Information System (INIS)

    Schroer, B.


    The work of Kadanoff, Wilson and Wegner, in the language of Euclidian field theory, is revised. In addition to Wilson's renormalization group method, which is based on the idea of eliminating short range fluctuations, the renormalization method of quantum field theory is discussed, which, in the present context, is called reparametrization (in order to avoid confusion). A reparametrization which is of particular interest in the theory of critical phenomena is the one which leads to scaling equations. New scaling equations which remain free of infrared divergences in two and three dimensions, are derived. The method allows a rather compact and unified discussion of Kadanoff's scaling laws and the related concept of global scaling fields, as well as the scale invariant correlation functions [pt

  4. Developing a new experimental system for an undergraduate laboratory exercise to teach theories of visuomotor learning. (United States)

    Kasuga, Shoko; Ushiba, Junichi


    Humans have a flexible motor ability to adapt their movements to changes in the internal/external environment. For example, using arm-reaching tasks, a number of studies experimentally showed that participants adapt to a novel visuomotor environment. These results helped develop computational models of motor learning implemented in the central nervous system. Despite the importance of such experimental paradigms for exploring the mechanisms of motor learning, because of the cost and preparation time, most students are unable to participate in such experiments. Therefore, in the current study, to help students better understand motor learning theories, we developed a simple finger-reaching experimental system using commonly used laptop PC components with an open-source programming language (Processing Motor Learning Toolkit: PMLT). We found that compared to a commercially available robotic arm-reaching device, our PMLT accomplished similar learning goals (difference in the error reduction between the devices, P = 0.10). In addition, consistent with previous reports from visuomotor learning studies, the participants showed after-effects indicating an adaptation of the motor learning system. The results suggest that PMLT can serve as a new experimental system for an undergraduate laboratory exercise of motor learning theories with minimal time and cost for instructors.

  5. [30 years' development of economic theories in confrontation with facts]. (United States)

    Levy, F


    In 1969, R. Frish and J. Tinbergen received the first Nobel Price in Economics. 200 years after Quesnay's "economic tables", economics were at last considered as a science. During the last thirty years, economics haven't lost their scientific reputation, but, confronted with different situations in the world and in France, economics have been unable to bring appropriate solutions to every problem. Nowadays, economics are quite far from the promises born after the Second World War: indeed, until the 1974 world crisis, Keynes' theory (from a macro-economic point of view) and Walras' formalisation of the markets (from a micro-economic point of view) were sufficient to give satisfying representations of any economic reality and mechanism. Nevertheless, these theories were unable to deal with both growing unemployment and raising inflation in the late 70's and early 80's. Today, economics present a wide variety of efficient analysis of society. Game theory, behaviour theory or econometrics are new means used to found new kinds of reality representation. Therefore, if economics can no longer be considered as an exact science, it remains nevertheless scientific.

    Directory of Open Access Journals (Sweden)

    Zulfo Godinjak


    Full Text Available Following the abdominal surgery, extensive adhesions often occur and they can cause difficulties during laparoscopic operations. However, previous laparotomy is not considered to be a contraindication for laparoscopy. The aim of this study is to present that an insertion of Veres needle in the region of umbilicus is a safe method for creating a pneumoperitoneum for laparoscopic operations after previous laparotomy. In the last three years, we have performed 144 laparoscopic operations in patients that previously underwent one or two laparotomies. Pathology of digestive system, genital organs, Cesarean Section or abdominal war injuries were the most common causes of previouslaparotomy. During those operations or during entering into abdominal cavity we have not experienced any complications, while in 7 patients we performed conversion to laparotomy following the diagnostic laparoscopy. In all patients an insertion of Veres needle and trocar insertion in the umbilical region was performed, namely a technique of closed laparoscopy. Not even in one patient adhesions in the region of umbilicus were found, and no abdominal organs were injured.

  15. Operator ordering in quantum optics theory and the development of Dirac's symbolic method

    International Nuclear Information System (INIS)

    Fan Hongyi


    We present a general unified approach for arranging quantum operators of optical fields into ordered products (normal ordering, antinormal ordering, Weyl ordering (or symmetric ordering)) by fashioning Dirac's symbolic method and representation theory. We propose the technique of integration within an ordered product (IWOP) of operators to realize our goal. The IWOP makes Dirac's representation theory and the symbolic method more transparent and consequently more easily understood. The beauty of Dirac's symbolic method is further revealed. Various applications of the IWOP technique, such as in developing the entangled state representation theory, nonlinear coherent state theory, Wigner function theory, etc, are presented.

  16. Evidence, Theory and Context: Using intervention mapping to develop a worksite physical activity intervention

    Directory of Open Access Journals (Sweden)

    Conner Mark


    Full Text Available Abstract Background The workplace is an ideal setting for health promotion. Helping employees to be more physically active can not only improve their physical and mental health, but can also have economic benefits such as reduced sickness absence. The current paper describes the development of a three month theory-based intervention that aims to increase levels of moderate intensity physical activity amongst employees in sedentary occupations. Methods The intervention was developed using an intervention mapping protocol. The intervention was also informed by previous literature, qualitative focus groups, an expert steering group, and feedback from key contacts within a range of organisations. Results The intervention was designed to target awareness (e.g. provision of information, motivation (e.g. goal setting, social support and environment (e.g. management support and to address behavioural (e.g. increasing moderate physical activity in work and interpersonal outcomes (e.g. encourage colleagues to be more physically active. The intervention can be implemented by local facilitators without the requirement for a large investment of resources. A facilitator manual was developed which listed step by step instructions on how to implement each component along with a suggested timetable. Conclusion Although time consuming, intervention mapping was found to be a useful tool for developing a theory based intervention. The length of this process has implications for the way in which funding bodies allow for the development of interventions as part of their funding policy. The intervention will be evaluated in a cluster randomised trial involving 1350 employees from 5 different organisations, results available September 2009.

  2. Applying Diffusion of Innovation Theory to Intervention Development. (United States)

    Dearing, James W


    Few social science theories have a history of conceptual and empirical study as long as does the diffusion of innovations. The robustness of this theory derives from the many disciplines and fields of study in which diffusion has been studied, from the international richness of these studies, and from the variety of new ideas, practices, programs, and technologies that have been the objects of diffusion research. Early theorizing from the beginning of the 20th century was gradually displaced by post hoc empirical research that described and explained diffusion processes. By the 1950s, diffusion researchers had begun to apply the collective knowledge learned about naturalistic diffusion in tests of process interventions to affect the spread of innovations. Now, this purposive objective has given form to a science of dissemination in which evidence-based practices are designed a priori not just to result in internal validity but to increase the likelihood that external validity and diffusion both are more likely to result. Here, I review diffusion theory and focus on seven concepts-intervention attributes, intervention clusters, demonstration projects, societal sectors, reinforcing contextual conditions, opinion leadership, and intervention adaptation-with potential for accelerating the spread of evidence-based practices, programs, and policies in the field of social work.

  3. [The development of Rein van Bemmelens (1904-1983) undation theory: forty years of Dutch geology]. (United States)

    Barzilay, Willemjan


    The Dutch geologist Rein van Bemmelen was the greatest opponent of plate tectonics in The Netherlands. He lived and worked during an important period in the history of earth sciences. He had studied geology when Wegeners theory was introduced and enthusiastically received in the Netherlands and he worked as a geologists during the period in which, after Wegeners theory was rejected in The Netherlands, several Dutch geologists came with their own theories to explain the origin of continents and oceans and in which plate tectonics was introduced in The Netherlands. He had proposed his own theory, the undation theory, at the beginning of the 1930s and kept on developing it during the following years. He continued to do so until his death in 1983. The history of the undation theory thus sheds light on the history of geology in The Netherlands. I will trace the history of geology in The Netherlands using Rein van Bemmelen and his undation theory as a lens.

    Full Text Available Lobbying studies have a long history in Russia, although there is still no profound understanding among scientists, politicians, business and civil society representatives what are the objects and goals of this process, who are actors of lobbying, where are the lines between formal and informal sides of lobbying. Current article examines lobbying in wider angle - through the mechanism of articulation of interests in the political system. Author also analyzes dynamics of lobbying as an informal institution using Gretchen Helmke and Steven Levitsky’s theory of comparative politics.

  5. Postcolonial theory, nursing knowledge, and the development of emancipatory knowing. (United States)

    Bickford, Deanna


    Nurses must assume a leadership role in confronting inequitable access to health care. This imperative is realizable through contributions to the knowledge of the discipline, reflecting on the profession's mandate for social justice and elimination of health inequities, as well as embracing the diversity of nursing's fundamental patterns of knowing. Emancipatory knowing involves critically examining social, political, and institutional structures to uncover social injustices and inequities and disrupt the status quo, as well as asking critical questions. Postcolonial theory, aligned with these foundational principles, can be used to answer such critical questions, thus contributing to the advancement of disciplinary knowledge.

  6. [I. P. Pavlov's theory on higher nervous activity: the landmarks and trends in its development]. (United States)

    Chilingarian, L I


    The theory of higher nervous activity created in Pavlovian time is compared with the present-day state of the theory developing due to appearance of new methods, techniques, facts, and concepts. Three principles of Pavlovian theory: determinism; analysis and synthesis; structural approach, as well s types of conditioned reflexes and techniques, types of higher nervous activity, and inhibition problems are discussed. The theory of higher nervous activity is schematically depicted as a tree, some branches of which are presented by facts and concepts obtained and introduced by I.P. Pavlov and his followers during his life, the others are formed by new facts and concepts advancing the theory. What is obsolete in the theory, what are the most prominent tendencies of its development and its new branches are discussed.

  7. Using diffusion of innovations theory to guide diabetes management program development: an illustrative example. (United States)

    De Civita, Mirella; Dasgupta, Kaberi


    Optimal management of type 2 diabetes requires achievement of optimal glucose, blood pressure and lipid targets through promotion of prudent diet, regular physical activity and adherence to necessary medication. This may require the development of new programs for the coordination of required multidisciplinary services. Diffusion of innovations theory offers a conceptual framework that may facilitate the implementation of such programs. To illustrate this, we have re-examined the implementation experiences previously reported by the developers of an actual diabetes management pilot program in Montreal, with an eye toward identifying potentially important process factors that could effectively increase adoption and sustainability. Physician participation in the program appeared to be influenced by perceived advantages of participation, compatibility of the program with own perspective and perceived barriers to participation. Organizational features that may have influenced participation included the extent of the program's integration within the existing health care system. A thorough consideration of process factors that impact system and team integration must equally include a focus on ensuring ongoing partnerships among the producers of the model, governments, nongovernmental organizations, private industry, user professionals and patients. This can only be achieved when a knowledge transfer action plan is developed to guide program development, implementation and sustainability.

    Iwasa, Y.; Michael, P. (Massachusetts Inst. of Tech., Cambridge, MA (United States)); Rabinowicz, E. (Massachusetts Inst. of Tech., Cambridge, MA (United States) Massachusetts Inst. of Tech., Cambridge, MA (United States). Francis Bitter National Magnet Lab.)


    High-performance superconducting solenoids are susceptible to premature quenches, or superconducting to normal state transitions, due to abrupt conductor movements within the winding. Abrupt motions involving 5{approximately}10{mu}m conductor displacements dissipate sufficient energy to trigger a quench. Sliding and mechanical behaviors of materials at cryogenic temperatures have been experimentally examined. After accounting for changes in the sliding materials' low-temperature strength properties, we have found that the adhesion theory of friction and wear remains applicable at cryogenic temperatures. The adhesion friction theory suggests two methods for controlling unsteady sliding motions. The first involves the selection of sliding materials whose friction coefficients increase with increasing sliding speed. A number of material pairs have been examined for positive friction-velocity characteristics. This materials-based approach to frictional stabilization does not seem a viable option at 4.2 K. The second altemative is to preprogram the force conditions within high-risk regions of the winding to regulate the occurrence of unsteady sliding motions. Structural models are proposed to account for unsteady conductor motions on a variety of dimensional scales. The models are used to design a small superconducting solenoid. Performance of this solenoid suggests that force-based motion control is a potentially viable design approach for achieving successful dry-wound magnets.

    Full Text Available This book review aims to discuss the new perspectives on theories of development provided by two outstanding scholars: Richard Peet and Elaine Hartwick in their recent published book “Theories of development: Contestations, Arguments, Alternatives”. An interesting point a view is presented from the beginning: development means a better life for everyone but economic growth can occur without touching problems like inequalities, poverty etc. The introductory chapter explains the differences between Growth and Development, and it is followed by a part I Conventional Theories of Development, part II Nonconventional Critical Theories of Development, part III Critical Modernism. Readers will find this book review intriguing and interesting enough to stimulate their curiosity to explore this fascinating book.

  12. Notes on Mathematical Language: Development Strings, Development Patterns, String Theory and Conditions Language

    CERN Document Server

    Struck, James T


    Mathematics, according to Lancelot Hogben, is the language of size, shape, and order. This note adds two words to the language of mathematics. First, a verb, develop or develops, is introduced to describe a development pattern or development string. These are patterns of development with examples from fibrillation, spread of electric changes in muscles and nerves, and matter changing into energy. The relevance of this idea to the idea in physics called String Theory is discussed. A critical comment on the use of the String, rather than other objects like circles, boxes, or spheres is made. Second, an adjective or adverb called conditions language is introduced. Equations like E=mc2, Coulomb's law, Newton's law of Gravitation, the equation for the definition of pie and the path to peace and war are discussed with relevance to the idea of conditions language. Conditions language is nothing more than including the relevant conditions where the equation works or when it applies in parentheses with the equation. V...

  13. Developing feasible loading patterns using perturbation theory methods

    International Nuclear Information System (INIS)

    White, J.R.; Avila, K.M.


    This work illustrates an approach to core reload design that combines the power of integer programming with the efficiency of generalized perturbation theory. The main use of the method is as a tool to help the design engineer identify feasible loading patterns with minimum time and effort. The technique is highly successful for the burnable poison (BP) loading problem, but the unpredictable behavior of the branch-and-bound algorithm degrades overall performance for large problems. Unfortunately, the combined fuel shuffling plus BP optimization problem falls into this latter classification. Overall, however, the method shows great promise for significantly reducing the manpower time required for the reload design process. And it may even give the further benefit of better designs and improved performance

    To design an effective computer science curriculum, educators require a systematic method of classifying the difficulty level of learning activities and assessment tasks. This is important for curriculum design and implementation and for communication between educators. Different educators must be able to use the method consistently, so that classified activities and assessments are comparable across the subjects of a degree, and, ideally, comparable across institutions. One widespread approach to supporting this is to write learning objects in terms of Bloom's Taxonomy. This, or other such classifications, is likely to be more effective if educators can use them consistently, in the way experts would use them. To this end, we present the design and evaluation of our online interactive web-based tutorial system, which can be configured and used to offer training in different classification schemes. We report on results from three evaluations. First, 17 computer science educators complete a tutorial on using Bloom's Taxonomy to classify programming examination questions. Second, 20 computer science educators complete a Neo-Piagetian tutorial. Third evaluation was a comparison of inter-rater reliability scores of computer science educators classifying programming questions using Bloom's Taxonomy, before and after taking our tutorial. Based on the results from these evaluations, we discuss the effectiveness of our tutorial system design for teaching computer science educators how to systematically and consistently classify programming examination questions. We also discuss the suitability of Bloom's Taxonomy and Neo-Piagetian theory for achieving this goal. The Bloom's and Neo-Piagetian tutorials are made available as a community resource. The contributions of this paper are the following: the tutorial system for learning classification schemes for the purpose of coding the difficulty of computing learning materials; its evaluation; new insights into the consistency

  16. A computational theory of hippocampal function, and tests of the theory: new developments. (United States)

    Kesner, Raymond P; Rolls, Edmund T


    The aims of the paper are to update Rolls' quantitative computational theory of hippocampal function and the predictions it makes about the different subregions (dentate gyrus, CA3 and CA1), and to examine behavioral and electrophysiological data that address the functions of the hippocampus and particularly its subregions. Based on the computational proposal that the dentate gyrus produces sparse representations by competitive learning and via the mossy fiber pathway forces new representations on the CA3 during learning (encoding), it has been shown behaviorally that the dentate gyrus supports spatial pattern separation during learning. Based on the computational proposal that CA3-CA3 autoassociative networks are important for episodic memory, it has been shown behaviorally that the CA3 supports spatial rapid one-trial learning, learning of arbitrary associations where space is a component, pattern completion, spatial short-term memory, and spatial sequence learning by associations formed between successive items. The concept that the CA1 recodes information from CA3 and sets up associatively learned backprojections to neocortex to allow subsequent retrieval of information to neocortex, is consistent with findings on consolidation. Behaviorally, the CA1 is implicated in processing temporal information as shown by investigations requiring temporal order pattern separation and associations across time; and computationally this could involve associations in CA1 between object and timing information that have their origins in the lateral and medial entorhinal cortex respectively. The perforant path input from the entorhinal cortex to DG is implicated in learning, to CA3 in retrieval from CA3, and to CA1 in retrieval after longer time intervals ("intermediate-term memory") and in the temporal sequence memory for objects.

  8. Henri Wallon's Theory of Early Child Development: The Role of Emotions (United States)



    The present paper gives an account of part of the stage theory of early child development of the French theorist Henri Wallon (1879-1962). Unlike his contemporary Jean Piaget, Wallon concentrated his efforts upon a description of the child's emotional development and the role emotions play in establishing the bond between child and caregiver. The description of Wallon's stage theory is preceded by biographical information and a presentation of his methodological views. It is argued that Wallon's theory is unique in its focus, exerted influence upon theorists such as Lev Vygotsky, and is basically compatible with modern insights about the nature of child development and the growth of intersubjectivity.

    Conclusion: Theory of mind development of mental retarded students varies based on that type of task being used to assess. In total, the claim of Theory-Theory approach, that says theory of mind development is on the basis of necessary processes, could be accepted. Also those theories which are based on cultural-social approaches calming that experience with other people causes development of mind understanding need to be more examined.

  10. Holodynski and Friedlmeyer's internalization model: Overview and criticism of a modern theory of emotional development

    Directory of Open Access Journals (Sweden)

    Mirić Jovan


    Full Text Available The paper presents a modern theory of emotional development - the Holodynski and Friedlmeyer's theory, as well as the criticism pointed at this theory. The author presents the key tenets of the theory: that emotional expressions of an infant are nonfocused, that the caregiver interprets and mirrors infant expressions, that an infant then imitates the expressions mirrored in such a way, that before speech occurs the expressions are transformed into signs, that those signs become internalized around the age of six, that auto-regulation later originates from social regulation of emotions. The author points out to similarities of this theory to the L. S. Vygotsky's theory of cognitive development. The critical commentary of the theory focuses on some of its shortcomings. First, the theory does not offer sufficient evidence in favor of the claim about the internalization of expressive signs. Second, some research findings contradict the assumption of caregiver's mirroring of infant's emotional expressions. Third, the internalization assumption implies that the (internalized sign does not only refer to, but even creates emotional feelings. Finally, the paper points out the various inconsistencies present in Holodynski and Friedlmeyer's text. The advantageous aspects of this theory are reflected in encompassing the whole life span and carrying important educational implications.

  17. Acoustic black holes: recent developments in the theory and applications. (United States)

    Krylov, Victor


    Acoustic black holes are relatively new physical objects that have been introduced and investigated mainly during the last decade. They can absorb almost 100% of the incident wave energy, and this makes them very attractive for such traditional engineering applications as vibration damping in different engineering structures and sound absorption in gases and liquids. They also could be useful for some ultrasonic devices using Lamb wave propagation to provide anechoic termination for such waves. So far, acoustic black holes have been investigated mainly for flexural waves in thin plates, for which the required gradual changes in local wave velocity with distance can be easily achieved by changing the plates' local thickness. The present paper provides a brief review of the theory of acoustic black holes, including their comparison with optic black holes introduced about five years ago. Review is also given of the recent experimental work carried out at Loughborough University on damping structural vibrations using the acoustic black hole effect. This is followed by the discussion on potential applications of the acoustic black hole effect for sound absorption in air.

  18. Determinism and probability in the development of the cell theory. (United States)

    Duchesneau, François


    A return to Claude Bernard's original use of the concept of 'determinism' displays the fact that natural laws were presumed to rule over all natural processes. In a more restricted sense, the term boiled down to a mere presupposition of constant determinant causes for those processes, leaving aside any particular ontological principle, even stochastic. The history of the cell theory until around 1900 was dominated by a twofold conception of determinant causes. Along a reductionist trend, cells' structures and processes were supposed to be accounted for through their analysis into detailed partial mechanisms. But a more holistic approach tended to subsume those analytic means and the mechanism involved under a program of global functional determinations. When mitotic and meiotic sequences in nuclear replication were being unveiled and that neo-Mendelian genetics was being grafted onto cytology and embryology, a conception of strict determinism at the nuclear level, principally represented by Wilhelm Roux and August Weismann, would seem to rule unilaterally over the mosaic interpretation of the cleavage of blastomeres. But, as shown by E.B. Wilson, in developmental processes there occur contingent outcomes of cell division which observations and experiments reveal. This induces the need to admit 'epigenetic' determinants and relativize the presumed 'preformation' of thedevelopmental phases by making room for an emergent order which the accidental circumstances of gene replication would trigger on.

  19. Reconceptualizing children's complex discharge with health systems theory: novel integrative review with embedded expert consultation and theory development. (United States)

    Noyes, Jane; Brenner, Maria; Fox, Patricia; Guerin, Ashleigh


    To report a novel review to develop a health systems model of successful transition of children with complex healthcare needs from hospital to home. Children with complex healthcare needs commonly experience an expensive, ineffectual and prolonged nurse-led discharge process. Children gain no benefit from prolonged hospitalization and are exposed to significant harm. Research to enable intervention development and process evaluation across the entire health system is lacking. Novel mixed-method integrative review informed by health systems theory. DATA  CINAHL, PsychInfo, EMBASE, PubMed, citation searching, personal contact. REVIEW  Informed by consultation with experts. English language studies, opinion/discussion papers reporting research, best practice and experiences of children, parents and healthcare professionals and purposively selected policies/guidelines from 2002-December 2012 were abstracted using Framework synthesis, followed by iterative theory development. Seven critical factors derived from thirty-four sources across five health system levels explained successful discharge (new programme theory). All seven factors are required in an integrated care pathway, with a dynamic communication loop to facilitate effective discharge (new programme logic). Current health system responses were frequently static and critical success factors were commonly absent, thereby explaining ineffectual discharge. The novel evidence-based model, which reconceptualizes 'discharge' as a highly complex longitudinal health system intervention, makes a significant contribution to global knowledge to drive practice development. Research is required to develop process and outcome measures at different time points in the discharge process and future trials are needed to determine the effectiveness of integrated health system discharge models. © 2013 John Wiley & Sons Ltd.

  1. Developing Dynamic Field Theory Architectures for Embodied Cognitive Systems withcedar. (United States)

    Lomp, Oliver; Richter, Mathis; Zibner, Stephan K U; Schöner, Gregor


    Embodied artificial cognitive systems, such as autonomous robots or intelligent observers, connect cognitive processes to sensory and effector systems in real time. Prime candidates for such embodied intelligence are neurally inspired architectures. While components such as forward neural networks are well established, designing pervasively autonomous neural architectures remains a challenge. This includes the problem of tuning the parameters of such architectures so that they deliver specified functionality under variable environmental conditions and retain these functions as the architectures are expanded. The scaling and autonomy problems are solved, in part, by dynamic field theory (DFT), a theoretical framework for the neural grounding of sensorimotor and cognitive processes. In this paper, we address how to efficiently build DFT architectures that control embodied agents and how to tune their parameters so that the desired cognitive functions emerge while such agents are situated in real environments. In DFT architectures, dynamic neural fields or nodes are assigned dynamic regimes, that is, attractor states and their instabilities, from which cognitive function emerges. Tuning thus amounts to determining values of the dynamic parameters for which the components of a DFT architecture are in the specified dynamic regime under the appropriate environmental conditions. The process of tuning is facilitated by the software framework cedar , which provides a graphical interface to build and execute DFT architectures. It enables to change dynamic parameters online and visualize the activation states of any component while the agent is receiving sensory inputs in real time. Using a simple example, we take the reader through the workflow of conceiving of DFT architectures, implementing them on embodied agents, tuning their parameters, and assessing performance while the system is coupled to real sensory inputs.

  2. Theory-inspired development of organic electro-optic materials. (United States)

    Sullivan, Philip A; Dalton, Larry R


    Correlated time-dependent density functional theory (TDDFT) quantum mechanical and pseudo-atomistic Monte Carlo (PAMC) statistical mechanical methods have been used to assist in the understanding of and to guide the improvement of organic electro-optic (OEO) materials, prepared by electric field poling of pi-electron chromophore-containing materials near their glass transition temperature. Theoretical treatment of the effects of dielectric permittivity and optical frequency on molecular (chromophore) first hyperpolarizabilities has been carried out as well as the analysis of the influence of spatially anisotropic intermolecular electrostatic interactions on the poling-induced noncentrosymmetric order of chromophores. Three classes of OEO materials have been considered in correlated theoretical and experimental investigations: (1) traditional chromophore/polymer composite materials, (2) chromophores covalently incorporated into polymers, dendrimers, and dendronized polymers, and (3) recently discovered materials consisting of chromophores incorporated into chromophore-containing host materials. This latter class of materials is referred to as binary chromophore organic glasses (BCOGs). These BCOGs exhibit exceptional electro-optic activity because of a combination of high chromophore number density, the effect of high dielectric permittivity on molecular first hyperpolarizability, and improved acentric order arising from the intermolecular electrostatic interactions among the two types of chromophores. The electrical conductivity of materials can also influence achievable electro-optic activity, and thin metal oxide buffer layers, introduced to limit charge injection, can significantly improve poling efficiency. Chromophore order can also be influenced, in some cases, by novel processing techniques, such as laser-assisted electric field poling. Thermal and photostability are important parameters for practical application of materials and have been improved

  5. Developing skills learning in obstetric nursing: approaches between theory and practice

    Directory of Open Access Journals (Sweden)

    Maria de Fátima Gomes Lima

    Full Text Available ABSTRACT Objective: To analyze the development of professional skills in an obstetric nursing graduate course. Method: Qualitative research, applying semi-structured interviews with 11 students in the obstetric nursing specialization at the State University of Ceará. Data was submitted to thematic review. Results: According to the subjects, the course offers the development of skills to strengthen and expand the range of activities in obstetric nursing. Despite relying on previous knowledge and experience acquired by the students, there is a gap between the content taught and internship practice, presented as challenges and difficulties faced by the students. The findings suggest a need for curricular revision, incorporating active teaching-learning methodologies, to overcome the disjunction between theory and practice. Final considerations: Students are part of a corpus that is potentially implicated in the construction and transformation of thoughts and values set forth by educational and health institutions, and it is necessary to make changes in political and social organizations, with a focus on providing comprehensive and egalitarian care to the population.

    Studies in accounting measurement indicate the absence of empirical relational structures that should form the basis for accounting measurement. This suggests the lack of objectivity of accounting information. Landmarks in the development of finance theory indicate the use of accounting measurement information as a basis for their development. This indicates that subjective accounting information is incorporated in finance theory. Consequently, this questions the status of finance as a univer...

  7. Between practice and theory: Melanie Klein, Anna Freud and the development of child analysis. (United States)

    Donaldson, G


    An examination of the early history of child analysis in the writings of Melanie Klein and Anna Freud reveals how two different and opposing approaches to child analysis arose at the same time. The two methods of child analysis are rooted in a differential emphasis on psychoanalytic theory and practice. The Kleinian method derives from the application of technique while the Anna Freudian method is driven by theory. Furthermore, by holding to the Freudian theory of child development Anna Freud was forced to limit the scope of child analysis, while Klein's application of Freudian practice has led to new discoveries about the development of the infant psyche.

  11. Leadership development in UK medical training: pedagogical theory and practice. (United States)

    Bekas, Stavros


    PHENOMENON: The central role of clinical leadership in achieving the vision of quality and productivity could be attained by investing in its development in postgraduate medical education. A critical review of selected literature is presented. The author identifies some of the main theoretical constructs related to leadership; the pedagogical underpinning of medical leadership programs; their learning objectives; and the mixture of methods, individual and collective, to achieve them. INSIGHTS: How to best develop leadership through medical education remains an open debate. Experiential learning, reflective practice, action learning, and mentoring could provide the foundations of leadership development. Application of the aforementioned should be cautious due to limitations of the concept of leadership as currently promoted and lack of robust evaluation methodologies.

  12. Theory for the alignment of cortical feature maps during development

    KAUST Repository

    Bressloff, Paul C.


    We present a developmental model of ocular dominance column formation that takes into account the existence of an array of intrinsically specified cytochrome oxidase blobs. We assume that there is some molecular substrate for the blobs early in development, which generates a spatially periodic modulation of experience-dependent plasticity. We determine the effects of such a modulation on a competitive Hebbian mechanism for the modification of the feedforward afferents from the left and right eyes. We show how alternating left and right eye dominated columns can develop, in which the blobs are aligned with the centers of the ocular dominance columns and receive a greater density of feedforward connections, thus becoming defined extrinsically. More generally, our results suggest that the presence of periodically distributed anatomical markers early in development could provide a mechanism for the alignment of cortical feature maps. © 2010 The American Physical Society.

Skin metastasis of lung carcinoma occurred only in the area previously irradiated. (Ueda, J.)

  14. Theory-Based Design and Development of a Socially Connected, Gamified Mobile App for Men About Breastfeeding (Milk Man) (United States)

    White, Becky K; Martin, Annegret; White, James A; Burns, Sharyn K; Maycock, Bruce R; Giglia, Roslyn C


    Background Despite evidence of the benefits of breastfeeding, babies are exclusively breastfed to the recommended 6 months. The support of the father is one of the most important factors in breastfeeding success, and targeting breastfeeding interventions to the father has been a successful strategy in previous research. Mobile technology offers unique opportunities to engage and reach populations to enhance health literacy and healthy behavior. Objective The objective of our study was to use previous research, formative evaluation, and behavior change theory to develop the first evidence-based breastfeeding app targeted at men. We designed the app to provide men with social support and information aiming to increase the support men can offer their breastfeeding partners. Methods We used social cognitive theory to design and develop the Milk Man app through stages of formative research, testing, and iteration. We held focus groups with new and expectant fathers (n=18), as well as health professionals (n=16), and used qualitative data to inform the design and development of the app. We tested a prototype with fathers (n=4) via a think-aloud study and the completion of the Mobile Application Rating Scale (MARS). Results Fathers and health professionals provided input through the focus groups that informed the app development. The think-aloud walkthroughs identified 6 areas of functionality and usability to be addressed, including the addition of a tutorial, increased size of text and icons, and greater personalization. Testers rated the app highly, and the average MARS score for the app was 4.3 out of 5. Conclusions To our knowledge, Milk Man is the first breastfeeding app targeted specifically at men. The development of Milk Man followed a best practice approach, including the involvement of a multidisciplinary team and grounding in behavior change theory. It tested well with end users during development. Milk Man is currently being trialed as part of the Parent

  1. Development of online use of theory of mind during adolescence: An eye-tracking study. (United States)

    Symeonidou, Irene; Dumontheil, Iroise; Chow, Wing-Yee; Breheny, Richard


    We investigated the development of theory of mind use through eye-tracking in children (9-13years old, n=14), adolescents (14-17.9years old, n=28), and adults (19-29years old, n=23). Participants performed a computerized task in which a director instructed them to move objects placed on a set of shelves. Some of the objects were blocked off from the director's point of view; therefore, participants needed to take into consideration the director's ignorance of these objects when following the director's instructions. In a control condition, participants performed the same task in the absence of the director and were told that the instructions would refer only to items in slots without a back panel, controlling for general cognitive demands of the task. Participants also performed two inhibitory control tasks. We replicated previous findings, namely that in the director-present condition, but not in the control condition, children and adolescents made more errors than adults, suggesting that theory of mind use improves between adolescence and adulthood. Inhibitory control partly accounted for errors on the director task, indicating that it is a factor of developmental change in perspective taking. Eye-tracking data revealed early eye gaze differences between trials where the director's perspective was taken into account and those where it was not. Once differences in accuracy rates were considered, all age groups engaged in the same kind of online processing during perspective taking but differed in how often they engaged in perspective taking. When perspective is correctly taken, all age groups' gaze data point to an early influence of perspective information. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

  2. Graphic display development methodology: Volume 1, Theory: Final report

    International Nuclear Information System (INIS)

    Pankrantz, D.


    The Graphic Display Development Program is intended to develop computer-based displays which support the symptomatic emergency operating procedures for BWRs. The purpose is to provide a technical basis and methodology for linking two post-TMI safety initiatives: improved operating procedures and the Safety Parameter Display System (NUREG-0737 Supplement 1). Whereas consistency between displays and emergency operating procedures is desirable, no assumption of such an NRC requirement is either expressed or implied in this document. Accordingly, this program should be viewed not as the only acceptable approach to SPDS design but as one of many possible approaches which may be pursued. This program has been supported as a generic activity on behalf of the Boiling Water Reactor Owner's Group (BWROG). No endorsement by any individual utility member of the BWROG is either expressed or implied in this document, nor is any utility obligated to implement this program at any plant

  3. Contacts, Social Capital and Market Institutions - A Theory of Development


    Dirk Bezemer; Uwe Dulleck; Paul Frijters


    This paper links two concepts of social capital to economic development. Social Capital (SC) appears in the litrature, on the individual level, as the number contacts of an agent has and his ability to raise contacts and, on the community level, as norms that help a society to function. In our economy, sold output increases with the creation of business contacts (Relational Capital as one aspect of SC). The cost of creating contacts is determined by community level social capital (CSC) and Ma...

  4. Management Science and Science Management: Prospects for Theory Development

    Current trends in the development of management science are characterized by increasing usage of advanced mathematics and by large scale computer programs and data structures based on simplistic formulations conforming to the requirements of traditional analytical techniques. What was originally conceived as management aids for practical operational problems is rapidly becoming an esoteric branch of mathematics ill-suited to most management concerns and incomprehensible to most managers.

  5. Method development at Nordic School of Public Health NHV: Phenomenology and Grounded Theory. (United States)

    Strandmark, Margaretha


    Qualitative methods such as phenomenology and grounded theory have been valuable tools in studying public health problems. A description and comparison of these methods. Phenomenology emphasises an inside perspective in form of consciousness and subjectively lived experiences, whereas grounded theory emanates from the idea that interactions between people create new insights and knowledge. Fundamental aspects of phenomenology include life world, consciousness, phenomenological reduction and essence. Significant elements in grounded theory are coding, categories and core categories, which develop a theory. There are differences in the philosophical approach, the name of the concept and the systematic tools between the methods. Thus, the phenomenological method is appropriate when studying emotional and existential research problems, and grounded theory is a method more suited to investigate processes. © 2015 the Nordic Societies of Public Health.

  7. Applying Bourdieu’s Field Theory to MLS Curricula Development

    DEFF Research Database (Denmark)

    Wien, Charlotte; Dorch, Bertil F.

    Our research question is: How can adequate education in Library and Information Science be provided for subject specialists in research libraries under constant change? Research libraries may be one of the places where imprints of the transition from industrial society to knowledge society are most...... evident. In order to keep up, the library profession has had to incorporate numerous new disciplines and has become a highly specialized area with its own Ph.D. program. But while developing the curricula within the discipline of library and information science (LIS), the training programs for the subject...... specialists of the research libraries tend to have been neglected in Denmark. Until the turn of the millennium, a subject specialist in a Danish research library would typically start their career by applying for a vacancy in connection with a subject specialist’s MA or Ph.D. specialization...

  8. The assessment of professional competence: building blocks for theory development. (United States)

    van der Vleuten, C P M; Schuwirth, L W T; Scheele, F; Driessen, E W; Hodges, B


    This article presents lessons learnt from experiences with assessment of professional competence. Based on Miller's pyramid, a distinction is made between established assessment technology for assessing 'knows', 'knowing how' and 'showing how' and more recent developments in the assessment of (clinical) performance at the 'does' level. Some general lessons are derived from research of and experiences with the established assessment technology. Here, many paradoxes are revealed and empirical outcomes are often counterintuitive. Instruments for assessing the 'does' level are classified and described, and additional general lessons for this area of performance assessment are derived. These lessons can also be read as general principles of assessment (programmes) and may provide theoretical building blocks to underpin appropriate and state-of-the-art assessment practices.

  9. The Development of Bimodal Bilingualism: Implications for Linguistic Theory. (United States)

    Lillo-Martin, Diane; de Quadros, Ronice Müller; Pichler, Deborah Chen


    A wide range of linguistic phenomena contribute to our understanding of the architecture of the human linguistic system. In this paper we present a proposal dubbed Language Synthesis to capture bilingual phenomena including code-switching and 'transfer' as automatic consequences of the addition of a second language, using basic concepts of Minimalism and Distributed Morphology. Bimodal bilinguals, who use a sign language and a spoken language, provide a new type of evidence regarding possible bilingual phenomena, namely code-blending, the simultaneous production of (aspects of) a message in both speech and sign. We argue that code-blending also follows naturally once a second articulatory interface is added to the model. Several different types of code-blending are discussed in connection to the predictions of the Synthesis model. Our primary data come from children developing as bimodal bilinguals, but our proposal is intended to capture a wide range of bilingual effects across any language pair.

  10. Explaining Michigan: developing an ex post theory of a quality improvement program. (United States)

    Dixon-Woods, Mary; Bosk, Charles L; Aveling, Emma Louise; Goeschel, Christine A; Pronovost, Peter J


    Understanding how and why programs work-not simply whether they work-is crucial. Good theory is indispensable to advancing the science of improvement. We argue for the usefulness of ex post theorization of programs. We propose an approach, located within the broad family of theory-oriented methods, for developing ex post theories of interventional programs. We use this approach to develop an ex post theory of the Michigan Intensive Care Unit (ICU) project, which attracted international attention by successfully reducing rates of central venous catheter bloodstream infections (CVC-BSIs). The procedure used to develop the ex post theory was (1) identify program leaders' initial theory of change and learning from running the program; (2) enhance this with new information in the form of theoretical contributions from social scientists; (3) synthesize prior and new information to produce an updated theory. The Michigan project achieved its effects by (1) generating isomorphic pressures for ICUs to join the program and conform to its requirements; (2) creating a densely networked community with strong horizontal links that exerted normative pressures on members; (3) reframing CVC-BSIs as a social problem and addressing it through a professional movement combining "grassroots" features with a vertically integrating program structure; (4) using several interventions that functioned in different ways to shape a culture of commitment to doing better in practice; (5) harnessing data on infection rates as a disciplinary force; and (6) using "hard edges." Updating program theory in the light of experience from program implementation is essential to improving programs' generalizability and transferability, although it is not a substitute for concurrent evaluative fieldwork. Future iterations of programs based on the Michigan project, and improvement science more generally, may benefit from the updated theory present here. © 2011 Milbank Memorial Fund.

  11. Development of a Self-Management Theory-Guided Discharge Intervention for Parents of Hospitalized Children. (United States)

    Sawin, Kathleen J; Weiss, Marianne E; Johnson, Norah; Gralton, Karen; Malin, Shelly; Klingbeil, Carol; Lerret, Stacee M; Thompson, Jamie J; Zimmanck, Kim; Kaul, Molly; Schiffman, Rachel F


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

  12. Contemporary foundations of the theory of urban development – case study smart, slow and compact city theory

    Directory of Open Access Journals (Sweden)

    Rysz Kamil


    Full Text Available The issue of the concept of development and urban planning in an optimal manner is as old as cities. It has not yet been established which human activities are to be considered as conscious and planned space development. It is assumed that the beginnings of rational, thoughtful urban planning should be sought at a time when cities began to be treated as a single organism, which should function smoothly, guarantee the safety of its inhabitants through defence functions and provide a higher standard of living. The effect of these assumptions was the logical placement of buildings, transportation systems and infrastructure, as well as recreational areas so that life in the city was something more than just miserable existence. This article overlooks former planning theories such as the theories of location by J.H. von Thunen or A. Weber, as well as the projects of a garden city by E. Howard and Functional Warsaw by J. Chmielewski and S. Syrkus. Instead, it focuses on what is currently, at the beginning of the 21st century, up to date and combines contemporary concepts of sustainability and new technologies, and treats the city as a resource of limited space, buildings, infrastructure and people representing both purchasing power and the labour force. The article, apart from theoretical considerations, focused on realizations of ideas in practice, quoting both sectoral solutions related to the organization of transportation in the city, as well as to projects of entire cities.

  13. Development of a phenomena identification and ranking table using fuzzy set theory

    Energy Technology Data Exchange (ETDEWEB)

    Kljenak, I.; Jordan Cizelj, R.; Prosek, A. [Jozef Stefan Institute, Reactor Engineering Div., Ljubljana (Slovenia)


    The use of fuzzy set theory in the development of Phenomena Identification and Ranking Table for a nuclear power plant transient is presented. Fuzzy set theory was used to aggregate the opinions from different experts concerning the importance of individual basic phenomena with respect to safety criteria. The use of fuzzy set theory is particularly adequate, as experts' opinions are inherently imprecise and uncertain. The method is presented on the specific case of a small-break loss-of-coolant accident in a two-loop pressurized water reactor. (author)

  14. Theory of development of surface topography under spatiotemporally heterogeneous sputtering conditions

    Carter, G.; Nobes, M.J. (Salford Univ. (UK). Thin Film and Surface Research Centre)


    A general theory of the development of surface topography of three-dimensional systems as a result of sputtering erosion and related processes is given. The theory is based upon a treatment of the surface as an advancing wavefront with spatio-temporally variable wavefront velocity appropriate to anisotropic, inhomogeneous media. The relevance of the theory to cases of stratified substrates, including polycrystals, dislocated crystals and contaminated surfaces, and to spatially scanned ion fluxes or substrates and rotated substrates is shown and a specific example of erosion at a grain boundary explored in detail.

  16. Theoretical development in the context of nursing-The hidden epistemology of nursing theory. (United States)

    Hoeck, Bente; Delmar, Charlotte


    This article is about nursing theories, the development of nursing knowledge and the underlying, hidden epistemology. The current technical-economical rationality in society and health care calls for a specific kind of knowledge based on a traditional Western, Socratic view of science. This has an immense influence on the development of nursing knowledge. The purpose of the article was therefore to discuss the hidden epistemology of nursing knowledge and theories seen in a broad historical context and point to an alternative epistemology for a future context. It is a question about which nursing theories and what nursing knowledge should be developed in order to benefit patients and relatives of the future. We suggest that future knowledge development in nursing be developed in an interchange between theory and practice and guided by philosophy like a kind of pendulum where all three elements are treated as equals. We suggest a framework for the development of nursing knowledge based on a caring-ethical practice, a theory on life phenomena in suffering and relationship-based nursing, and thereby, we may be able to help patients to be cured, to recover, to be alleviated or comforted when suffering. © 2017 John Wiley & Sons Ltd.

    Here the recently developed size-dependent piezoelectricity and the strain gradient theory of flexoelectricity are compared. In the course of this investigation, the strain gradient theory of flexoelectricity is shown to violate fundamental rules of mathematics, continuum mechanics and electromagnetism. The major difficulties are associated with ill-posed boundary conditions, the missing angular (moment) equilibrium equation and the appearance of a non-physical extraneous vectorial electrosta...

  18. The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions. (United States)

    Portin, Petter


    The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

  20. A social network model for the development of a 'Theory of Mind' (United States)

    Harré, Michael S.


    A "Theory of Mind" is one of the most important skills we as humans have developed; It enables us to infer the mental states and intentions of others, build stable networks of relationships and it plays a central role in our psychological make-up and development. Findings published earlier this year have also shown that we as a species as well as each of us individually benefit from the enlargement of the underlying neuro-anatomical regions that support our social networks, mediated by our Theory of Mind that stabilises these networks. On the basis of such progress and that of earlier work, this paper draws together several different strands from psychology, behavioural economics and network theory in order to generate a novel theoretical representation of the development of our social-cognition and how subsequent larger social networks enables much of our cultural development but at the increased risk of mental disorders.

  1. Hemodialysis arteriovenous fistula self-cannulation: moving theory to practice in developing patient-teaching resources. (United States)

    Hudson, Shawna; Macdonald, Marilyn


    This article discusses how Orem's theory was applied to the revision of supporting documents in the patient-teaching process and subsequently the nurse's role in the patient's learning experience. Teaching based on didactic, provider-focused objectives is ineffective in meeting patient's learning needs. There is a lack of conclusive research on the development of appropriate patient-teaching endeavors for the acquisition of knowledge and skills related to the performance of hemodialysis arteriovenous fistula self-cannulation. To prepare patients for home hemodialysis, Orem's self-care-deficit nursing theory was used to guide the revisions of a patient assessment and learning documentation template, the development of a self-cannulation teaching resource and to foster a renewed sense of the nurse's role in the teaching process. The application of self-care-deficit nursing theory to the update and development of patient-teaching documentation and resources for self-cannulation provides the nurse with a theoretical approach to assess, plan, evaluate, and document teaching from a patient-focused perspective. Theory in practice provides a means to support and highlight the role of nurses in the patient-learning process. The utilization of practical activities to introduce theory into teaching provides a means to structure care processes and to enhance nurse's adoption of theory in practice. Orem's theory provides a relevant, useful framework to guide nurses in teaching patients self-care. Research on the exploration of nurse's attitudes related to the benefit of adopting theory when teaching patients to perform hemodialysis self-care is needed.

  2. Recent developments in classical density functional theory: Internal energy functional and diagrammatic structure of fundamental measure theory

    Directory of Open Access Journals (Sweden)

    M. Schmidt


    Full Text Available An overview of several recent developments in density functional theory for classical inhomogeneous liquids is given. We show how Levy's constrained search method can be used to derive the variational principle that underlies density functional theory. An advantage of the method is that the Helmholtz free energy as a functional of a trial one-body density is given as an explicit expression, without reference to an external potential as is the case in the standard Mermin-Evans proof by reductio ad absurdum. We show how to generalize the approach in order to express the internal energy as a functional of the one-body density distribution and of the local entropy distribution. Here the local chemical potential and the bulk temperature play the role of Lagrange multipliers in the Euler-Lagrange equations for minimiziation of the functional. As an explicit approximation for the free-energy functional for hard sphere mixtures, the diagrammatic structure of Rosenfeld's fundamental measure density functional is laid out. Recent extensions, based on the Kierlik-Rosinberg scalar weight functions, to binary and ternary non-additive hard sphere mixtures are described.

  12. Demystifying internalization and socialization: linking conceptions of how development happens to organismic-developmental theory. (United States)

    Raeff, Catherine


    Internalization and socialization are central constructs in developmental psychology for explaining and investigating how development happens through social interaction. There has been and continues to be much debate about how to conceptualize and investigate these processes. The ways in which internalization and socialization promote development have also been difficult to identify. The goal of this chapter is to offer a way of clarifying what happens during internalization and socialization by linking them to a clear conceptualization of development. The chapter first provides an overview of internalization and socialization theory and research. This review indicates that the focus on how development happens through social interaction has taken attention away from specifying the developmental changes that occur through social interaction. It is argued that understanding internalization and socialization can be enhanced by linking them to a clear definition of development, such as the one provided by organismic-developmental theory. According to organismic-developmental theory, developmental change is distinguished from any change that may occur over time. Rather, development is defined in terms of the differentiation and integration of action components in relation to cultural values and expectations for development. After explicating organismic-developmental theory's key claims, some implications of utilizing it for advancing an understanding of internalization and socialization are discussed. The chapter ends with suggestions for future research on internalization, socialization, and development.

  13. Development of a rapid lateral flow immunoassay test for detection of exosomes previously enriched from cell culture medium and body fluids. (United States)

    Exosomes are cell-secreted nanovesicles (40-200 nm) that represent a rich source of novel biomarkers in the diagnosis and prognosis of certain diseases. Despite the increasingly recognized relevance of these vesicles as biomarkers, their detection has been limited due in part to current technical challenges in the rapid isolation and analysis of exosomes. The complexity of the development of analytical platforms relies on the heterogeneous composition of the exosome membrane. One of the most attractive tests is the inmunochromatographic strips, which allow rapid detection by unskilled operators. We have successfully developed a novel lateral flow immunoassay (LFIA) for the detection of exosomes based on the use of tetraspanins as targets. We have applied this platform for the detection of exosomes purified from different sources: cell culture supernatants, human plasma and urine. As proof of concept, we explored the analytical potential of this LFIA platform to accurately quantify exosomes purified from a human metastatic melanoma cell line. The one-step assay can be completed in 15 min, with a limit of detection of 8.54×10(5) exosomes/µL when a blend of anti-CD9 and anti-CD81 were selected as capture antibodies and anti-CD63 labelled with gold nanoparticles as detection antibody. Based on our results, this platform could be well suited to be used as a rapid exosome quantification tool, with promising diagnostic applications, bearing in mind that the detection of exosomes from different sources may require adaptation of the analytical settings to their specific composition.

  15. Exploring the relation between People’s Theories of Intelligence and Beliefs about Brain Development

    Directory of Open Access Journals (Sweden)

    Ashley J Thomas


    Full Text Available A person’s belief about whether intelligence can change (called their implicit theory of intelligence predicts something about that person’s thinking and behavior. People who believe intelligence is fixed (called entity theorists attribute failure to traits (i.e. I failed the test because I’m not smart. and tend to be less motivated in school; those who believe intelligence is malleable (called incremental theorists tend to attribute failure to behavior (i.e. I failed the test because I didn’t study. and are more motivated in school. In previous studies, researchers have characterized participants as either entity or incremental theorists based on their agreement or disagreement with three statements. The present study further explored the theories-of-intelligence construct in two ways: first, we asked whether these theories are coherent, in the sense that they show up not only in participants’ responses to the three standard assessment items, but on a broad range of questions about intelligence and the brain. Second, we asked whether these theories are discrete or continuous. In other words, we asked whether people one thing or the other (i.e. that intelligence is malleable or fixed, or if there is a continuous range of beliefs (i.e., people believe in malleability to a greater or lesser degree. Study (1 asked participants a range of general questions about the malleability of intelligence and the brain. Study (2 asked participants more specific questions about the brains of a pair of identical twins who were separated at birth. Results showed that theories of intelligence are coherent: participants’ responses to the three standard survey items are correlated with their responses to questions about the brain. But the theories are not discrete: although responses to the three standard survey items fell into a bimodal distribution, responses to the broader range of questions fell into a normal distribution suggesting the theories are

    Efforts at cumulative knowledge building in social gerontology have been lax, judging from research articles published in journals between 1990 and 1994. Too little attention has been paid to the cumulative development of theory; readers are left with many empirical generalizations but underdeveloped explanations by which to interpret findings and build upon them in subsequent research. To assist future theory development in social gerontology, we review seven theoretical perspectives referenced most frequently in recent journals: (1) social constructionist, (2) social exchange, (3) life course, (4) feminist, (5) age stratification (age and society), (6) political economy of aging, and (7) critical theory. We suggest that, taken together, these represent a "third generation" of explanation in social gerontology, noting their debt to older and more established traditions in social science theory. We argue that authors and journal reviewers should place more emphasis on theory development - which means, most simply, the construction of explicit explanations in accounting for empirical findings - if knowledge development about social aspects of aging is to be cumulative, systematic, and incremental.

  18. The Development of Bayesian Theory and Its Applications in Business and Bioinformatics (United States)

    Zhang, Yifei


    Bayesian Theory originated from an Essay of a British mathematician named Thomas Bayes in 1763, and after its development in 20th century, Bayesian Statistics has been taking a significant part in statistical study of all fields. Due to the recent breakthrough of high-dimensional integral, Bayesian Statistics has been improved and perfected, and now it can be used to solve problems that Classical Statistics failed to solve. This paper summarizes Bayesian Statistics’ history, concepts and applications, which are illustrated in five parts: the history of Bayesian Statistics, the weakness of Classical Statistics, Bayesian Theory and its development and applications. The first two parts make a comparison between Bayesian Statistics and Classical Statistics in a macroscopic aspect. And the last three parts focus on Bayesian Theory in specific -- from introducing some particular Bayesian Statistics’ concepts to listing their development and finally their applications.

  19. Inhabiting the sexual landscape: toward an interpretive theory of the development of sexual orientation and identity. (United States)

    Gordon, Liahna E; Silva, Tony J


    Building on Paula Rust's (1996) concept of a sexual landscape, we propose an interpretive theory of the development of both sexual orientation and sexual identity. We seek to reconcile human agency with active and shifting influences in social context and to recognize the inherent complexity of environmental factors while acknowledging the role that biological potential plays. We ground our model in the insights of three compatible and related theoretical perspectives: social constructionism, symbolic interactionism, and scripting theory. Within this framework, we explain how sexual orientation and sexual identities develop and potentially change.

  20. Intervention mapping protocol for developing a theory-based diabetes self-management education program. (United States)

    Song, Misoon; Choi, Suyoung; Kim, Se-An; Seo, Kyoungsan; Lee, Soo Jin


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

  1. Development of mean field theories in nuclear physics and in desordered media

    International Nuclear Information System (INIS)

    Orland, Henri.


    This work, in two parts, deals with the development of mean field theories in nuclear physics (nuclei in balance and collisions of heavy ions) as well as in disordered media. In the first part, two different ways of tackling the problem of developments around mean field theories are explained. Possessing an approach wave function for the system, the natural idea for including the correlations is to develop the exact wave function of the system around the mean field wave function. The first two chapters show two different ways of dealing with this problem: the perturbative approach - Hartree-Fock equations with two body collisions and functional methods. In the second part: mean field theory for spin glasses. The problem for spin glasses is to construct a physically acceptable mean field theory. The importance of this problem in statistical mechanics is linked to the fact that the mean field theory provides a qualitative description of the low temperature phase and is the starting point needed for using more sophisticated methods (renormalization group). Two approaches to this problem are presented, one based on the Sherrington-Kirkpatrick model and the other based on a model of spins with purely local disorder and competitive interaction between the spins [fr

  2. Developing the master learner: applying learning theory to the learner, the teacher, and the learning environment. (United States)

    Schumacher, Daniel J; Englander, Robert; Carraccio, Carol


    As a result of the paradigm shift to a competency-based framework, both self-directed lifelong learning and learner-centeredness have become essential tenets of medical education. In the competency-based framework, learners drive their own educational process, and both learners and teachers share the responsibility for the path and content of learning. This learner-centered emphasis requires each physician to develop and maintain lifelong learning skills, which the authors propose culminate in becoming a "master leaner." To better understand the development of these skills and the attainment of that goal, the authors explore how learning theories inform the development of master learners and how to translate these theories into practical strategies for the learner, the teacher, and the learning environment so as to optimize this development.The authors begin by exploring self-determination theory, which lays the groundwork for understanding the motivation to learn. They next consider the theories of cognitive load and situated cognition, which inform the optimal context and environment for learning. Building from this foundation, the authors consider key educational theories that affect learners' abilities to serve as primary drivers of their learning, including self-directed learning (SDL); the self-assessment skills necessary for SDL; factors affecting self-assessment (self-concept, self-efficacy, illusory superiority, gap filling); and ways to mitigate the inaccuracies of self-assessment (reflection, self-monitoring, external information seeking, and self-directed assessment seeking).For each theory, they suggest practical action steps for the learner, the teacher, and the learning environment in an effort to provide a road map for developing master learners.

  3. The Eukaryotic Microbiome: Origins and Implications for Fetal and Neonatal life note bene: previous titles: The Microbiome in the Development of Terrestrial Life,and,The Origins and Development of the Neonatal Microbiome

    Directory of Open Access Journals (Sweden)

    William B. Miller


    Full Text Available All eukaryotic organisms are holobionts representing complex collaborations between the entire microbiome of each eukaryote and its innate cells. These linked constituencies form complex localized and interlocking ecologies in which the specific microbial constituents and their relative abundance differ substantially according to age and environmental exposures. Rapid advances in microbiology and genetic research techniques have uncovered a significant previous underestimate of the extent of that microbial contribution and its metabolic and developmental impact on holobionts. Therefore, a re-calibration of the neonatal period is suggested as a transitional phase in development that includes the acquisition of consequential collaborative microbial life from extensive environmental influences. These co-dependent, symbiotic relationships formed in the fetal and neonatal stages extend into adulthood and even across generations.

  5. The contribution of several Nobel Laureates in the development of the Theory of general economic equilibrium

    Directory of Open Access Journals (Sweden)

    Florentina Xhelili Krasniqi


    Full Text Available Nobel Laureates with their contributions to the development of the theory of general equilibrium have enabled this theory to be one of the most important for theoretical and practical analysis of the overall economy and the efficient use of economic resources. Results of the research showing that contributions of Nobel Laureates in the economy belong to two main frameworks of development of the general equilibrium theory: one was the mathematical model of general equilibrium developed by John R. Hicks (1939, Kenneth J.Arrow (1951 and Gerard Debreu (1954 and second frames of general equilibrium belongs to Paul A. Samuelson (1958. To highlight the contributions of these Nobel laureates in the development of the theory of general equilibrium have been selected and are presented in the paper some views, estimates and assumptions that have contributed not only in solving concrete problems, but also to the development of economic science in general. Their works represent a synthesis of theoretical and practical aspects of treatment of general equilibrium which are the starting point for further research in this field.

  6. Review of Grain Refinement of Cast Metals Through Inoculation: Theories and Developments (United States)

    Liu, Zhilin


    The inoculation method of grain refinement is widely used in research and industry. Because of its commercial and engineering importance, extensive research on the mechanisms/theories of grain refinement and development of effective grain refiners for diverse cast metals/alloys has been conducted. In 1999, Easton and St. John reviewed the mechanisms of grain refinement of cast Al alloys. Since then, grain refinement in alloys of Al, Mg, Fe, Ti, Cu, and Zn has evolved a lot. However, there is still no full consensus on the mechanisms/theories of grain refinement. Moreover, some new grain refiners developed based on the theories do not ensure efficient grain refinement. Thus, the factors that contribute to grain refinement are still not fully understood. Clarification of the prerequisite issues that occur in grain refinement is required using recent theories. This review covers multiple metals/alloys and developments in grain refinement from the last twenty years. The characteristics of effective grain refiners are considered from four perspectives: effective particle/matrix wetting configuration, sufficiently powerful segregating elements, preferential crystallographic matching, and geometrical features of effective nucleants. Then, recent mechanisms/theories on the grain refinement of cast metals/alloys are reviewed, including the peritectic-related, hypernucleation, inert nucleant, and constitutional supercooling-driven theories. Further, developments of deterministic and probabilistic modeling and nucleation crystallography in the grain refinement of cast metals are reviewed. Finally, the latest progress in the grain refinement of cast Zn and its alloys is described, and future work on grain refinement is summarized.

  7. What theory, for whom and in which context? Reflections on the application of theory in the development and evaluation of complex population health interventions. (United States)

    Moore, Graham F; Evans, Rhiannon E


    Recent years have seen a growing emphasis on the value of building and testing middle range theory throughout the development and evaluation of complex population health interventions. We agree that a coherent theoretical basis for intervention development, and use of evaluation to test key causal assumptions and build theory, are crucial. However, in this editorial, we argue that such recommendations have often been operationalised in somewhat simplistic terms with potentially perverse consequences, and that an uncritical assumption that an intervention explicitly based on theory is inherently superior carries significant risks. We first argue that the drive for theory-based approaches may have exacerbated a propensity to select 'off-the-shelf' theories, leading to the selection of inappropriate theories which distract attention from the mechanisms through which a problem is actually sustained. Second, we discuss a tendency toward over-reliance on individual-level theorising. Finally, we discuss the relatively slow progress of population health intervention research in attending to issues of context, and the ecological fit of interventions with the systems whose functioning they attempt to change. We argue that while researchers should consider a broad range of potential theoretical perspectives on a given population health problem, citing a popular off-the-shelf theory as having informed an intervention and its evaluation does not inherently make for better science. Before identifying or developing a theory of change, researchers should develop a clear understanding of how the problem under consideration is created and sustained in context. A broader conceptualisation of theory that reaches across disciplines is vital if theory is to enhance, rather than constrain, the contribution of intervention research. Finally, intervention researchers need to move away from viewing interventions as discrete packages of components which can be described in isolation from

  8. Role of Adult Learning Theories in the Development of Corporate Training in the USA

    Directory of Open Access Journals (Sweden)

    Iryna Lytovchenko


    Full Text Available The article presents the analysis of the role of adult learning theories in the development of corporate training in the USA. Considering that corporate education is part of the adult education system in this country, the author examines theories of organizational learning in the context of adult learning. The results of the study have revealed that adult education in the US is based on dif erent learning theories which should be viewed from the perspective of several main orientations: behaviorism, cognitivism, humanism, developmental theories, social learning, constructivism, which have dif erent philosophical background and, accordingly, different understanding of the nature and methodology of adult learning. Based on the results of the study it has been concluded that theories of organizational learning which explain motivation of students, their needs and goals, cognitive processes and other aspects of the learning in organizations and have had the main influence on the development of corporate education in the United States should be viewed in the context of the above-mentioned basic orientations to learning, too. From the methodological perspective, the research was based on interdisciplinary and systemic approaches. Thus, we used a set of interrelated research methods: comparative, structural, systemic-functional analyses, comparison and synthesis.

  9. A new intuitionism: Meaning, memory, and development in Fuzzy-Trace Theory. (United States)

    Reyna, Valerie F


    Combining meaning, memory, and development, the perennially popular topic of intuition can be approached in a new way. Fuzzy-trace theory integrates these topics by distinguishing between meaning-based gist representations, which support fuzzy (yet advanced) intuition, and superficial verbatim representations of information, which support precise analysis. Here, I review the counterintuitive findings that led to the development of the theory and its most recent extensions to the neuroscience of risky decision making. These findings include memory interference (worse verbatim memory is associated with better reasoning); nonnumerical framing (framing effects increase when numbers are deleted from decision problems); developmental decreases in gray matter and increases in brain connectivity; developmental reversals in memory, judgment, and decision making (heuristics and biases based on gist increase from childhood to adulthood, challenging conceptions of rationality); and selective attention effects that provide critical tests comparing fuzzy-trace theory, expected utility theory, and its variants (e.g., prospect theory). Surprising implications for judgment and decision making in real life are also discussed, notably, that adaptive decision making relies mainly on gist-based intuition in law, medicine, and public health.

  11. Residents’ Attitude toward Aboriginal Cultural Tourism Development: An Integration of Two Theories

    Directory of Open Access Journals (Sweden)

    Chi-Ming Hsieh


    Full Text Available Understanding residents’ attitudes is critical for successfully developing cultural tourism in aboriginal protected areas. This study developed an integration model combining two theories to identify the key determinants of indigenous residents’ attitudes toward cultural tourism development. Social exchange theory stresses the impact of the benefits derived from tourism on indigenous residents’ attitudes toward tourism development. Social capital theory embeds clear rationales for strengthening the internalization process of the formation of residents’ shared values and understanding, enabling them to trust each other and thus support tourism development. The present study was conducted within two indigenous communities in Eastern Taiwan. The results revealed that cultural tourism benefits and structural and relational capital effectively predict indigenous residents’ attitudes toward tourism development; structural capital plays a critical mediating role in the relationship between tourism benefits and residents’ attitudes. The managerial implications provide recommendations for aboriginal community developers or practical sectors to avoid problems or costs caused by tourism development when promoting cultural tourism activities within indigenous communities.

  7. Biaxial experiments supporting the development of constitutive theories for advanced high-temperature materials (United States)

    Ellis, J. R.


    Complex states of stress and strain are introduced into components during service in engineering applications. It follows that analysis of such components requires material descriptions, or constitutive theories, which reflect the tensorial nature of stress and strain. For applications involving stress levels above yield, the situation is more complex in that material response is both nonlinear and history dependent. This has led to the development of viscoplastic constitutive theories which introduce time by expressing the flow and evolutionary equation in the form of time derivatives. Models were developed here which can be used to analyze high temperature components manufactured from advanced composite materials. In parallel with these studies, effort was directed at developing multiaxial testing techniques to verify the various theories. Recent progress in the development of constitutive theories from both the theoretical and experimental viewpoints are outlined. One important aspect is that material descriptions for advanced composite materials which can be implemented in general purpose finite element codes and used for practical design are verified.

  11. Development of the theory of momentum distribution of particles with regard to quantum phenomena (United States)

    Starostin, A. N.; Gryaznov, V. K.; Petrushevich, Yu. V.


    A generalization of the theory of quantum asymptotics for the particle distribution function for large values of momentum is given that takes into account the energy exchange between a particle and an impurity. It is shown that, compared with the known power-law asymptotics, an additional exponential dependence on the kinetic energy arises with effective temperature higher than the temperature of the medium by a factor of the ratio of the impurity mass to the particle mass for a quantum correction to the Maxwell distribution function. New formulas are obtained for the rates of thermonuclear and threshold chemical reactions, that allow one to get rid of the inconsistencies of the previous theory when comparing with experiment.

  13. Thermomechanical theory of materials undergoing large elastic and viscoplastic deformation (AWBA development program)

    International Nuclear Information System (INIS)

    Martin, S.E.; Newman, J.B.


    A thermomechanical theory of large deformation elastic-inelastic material behavior is developed which is based on a multiplicative decomposition of the strain. Very general assumptions are made for the elastic and inelastic constitutive relations and effects such as thermally-activated creep, fast-neutron-flux-induced creep and growth, annealing, and strain recovery are compatible with the theory. Reduced forms of the constitutive equations are derived by use of the second law of thermodynamics in the form of the Clausius-Duhem inequality. Observer invariant equations are derived by use of an invariance principle which is a generalization of the principle of material frame indifference

  15. Implementing software based on relation frame theory to develop and increase relational cognitive skills (United States)

    Presti, Giovambattista; Messina, Concetta; Mongelli, Francesca; Sireci, Maria Josè; Collotta, Mario


    Relational Frame Theory is a post-skinnerian theory of language and cognition based on more than thirty years of basic and applied research. It defines language and cognitive skills as an operant repertoire of responses to arbitrarily related stimuli specific, as far as is now known, of the human species. RFT has been proved useful in addressing cognitive barriers to human action in psychotherapy and also improving children skills in reading, IQ testing, and in metaphoric and categorical repertoires. We present a frame of action where RFT can be used in programming software to help autistic children to develop cognitive skills within a developmental vision.

    Grand Challenges for international health and development initiatives have received substantial funding to tackle unsolved problems; however, evidence of their effectiveness in achieving change is lacking. A theory of change may provide a useful tool to track progress towards desired outcomes. The Saving Lives at Birth partnership aims to address inequities in maternal-newborn survival through the provision of strategic investments for the development, testing and transition-to-scale of ground-breaking prevention and treatment approaches with the potential to leapfrog conventional healthcare approaches in low resource settings. We aimed to develop a theory of change and impact framework with prioritised metrics to map the initiative's contribution towards overall goals, and to measure progress towards improved outcomes around the time of birth. A theory of change and impact framework was developed retrospectively, drawing on expertise across the partnership and stakeholders. This included a document and literature review, and wide consultation, with feedback from stakeholders at all stages. Possible indicators were reviewed from global maternal-newborn health-related partner initiatives, priority indicator lists, and project indicators from current innovators. These indicators were scored across five domains to prioritise those most relevant and feasible for Saving Lives at Birth. These results informed the identification of the prioritised metrics for the initiative. The pathway to scale through Saving Lives at Birth is articulated through a theory of change and impact framework, which also highlight the roles of different actors involved in the programme. A prioritised metrics toolkit, including ten core impact indicators and five additional process indicators, complement the theory of change. The retrospective nature of this development enabled structured reflection of the program mechanics, allowing for inclusion of learning from the first four rounds of the

    The publication is aimed at theoretical generalization of the global experience of development of the theory of spatial distribution of productive forces as the basis of regional economy. Considering the evolution of scientific views on the spatial development of territories, taking account of the particularities of the distribution of production, one can allocate and identify several paradigms, which replaced each other, but preserved their connection with the placement of ...

  20. The mind behind the message: Advancing theory of mind scales for typically developing children, and those with deafness, autism, or Asperger Syndrome (United States)

    Peterson, Candida C.; Wellman, Henry M.; Slaughter, Virginia


    Children aged 3 to 12 years (n=184) with typical development, deafness, autism or Asperger Syndrome took a series of theory-of-mind (ToM) tasks to confirm and extend previous developmental scaling evidence. A new sarcasm task, in the format of Wellman and Liu’s (2004) 5-step ToM scale, added a statistically reliable sixth step to the scale for all diagnostic groups. A key previous finding, divergence in task sequencing for children with autism, was confirmed. Comparisons among diagnostic groups, controlling age and language ability, showed that typical developers mastered the six ToM steps ahead of each of the three disabled groups, with implications for ToM theories. The final (sarcasm) task challenged even nondisabled 9-year-olds, demonstrating the new scale’s sensitivity to post-preschool ToM growth. PMID:22304467

  1. Development of a group work assessment pedagogy using constructive alignment theory. (United States)

    Croy, Suzanne R


    The purpose of this paper is to explore group work assessment underpinned by constructive alignment theory to develop a new assessment pedagogy. A review was undertaken of an existing module 'Mental Health Nursing 1', with student nurses participating in the BSc (Hons) Nursing Programme. Constructive alignment theory requires teachers to adopt a deep approach to learning where module learning outcomes are aligned with the teaching environment and modes of assessment. As the module progressed, reviewing the Mental Health Nursing 1 module became an excellent opportunity to begin to understand how constructive alignment theory can inform a group work assessment pedagogy. Working using a constructively aligned assessment process became a valuable learning experience for the module leader whilst at the same time revealed a gap in the research around the impact of constructively aligned teaching and group work assessment.

  2. Playing off the curve - testing quantitative predictions of skill acquisition theories in development of chess performance. (United States)

    Gaschler, Robert; Progscha, Johanna; Smallbone, Kieran; Ram, Nilam; Bilalić, Merim


    Learning curves have been proposed as an adequate description of learning processes, no matter whether the processes manifest within minutes or across years. Different mechanisms underlying skill acquisition can lead to differences in the shape of learning curves. In the current study, we analyze the tournament performance data of 1383 chess players who begin competing at young age and play tournaments for at least 10 years. We analyze the performance development with the goal to test the adequacy of learning curves, and the skill acquisition theories they are based on, for describing and predicting expertise acquisition. On the one hand, we show that the skill acquisition theories implying a negative exponential learning curve do a better job in both describing early performance gains and predicting later trajectories of chess performance than those theories implying a power function learning curve. On the other hand, the learning curves of a large proportion of players show systematic qualitative deviations from the predictions of either type of skill acquisition theory. While skill acquisition theories predict larger performance gains in early years and smaller gains in later years, a substantial number of players begin to show substantial improvements with a delay of several years (and no improvement in the first years), deviations not fully accounted for by quantity of practice. The current work adds to the debate on how learning processes on a small time scale combine to large-scale changes.

  3. Theoretical foundations of international migration process studies: analysis of key migration theories development

    Directory of Open Access Journals (Sweden)

    Shymanska K.V.


    Full Text Available The need for transformation of Ukraine's migration policy based on globalized world development trends and in response to the challenges of European integration transformations causes the need of researching the theoretical and methodological basis of migration studies, and the regulations of existing theories of international migration. The bibliometric analysis of scientific publications on international migration in cites indexes found that the recent researches on these problems acquire interdisciplinary character. It necessitates the transformation of migration study approaches basing on economic, social, institutional theories and concepts synthesis. The article is devoted to the study of theoretical regulations of existing international migration theories in the context of the evolution of scientists’ views on this phenomenon. The author found that the existing theories of international migration should be divided into three categories (microeconomic, macroeconomic, globalizational that contributes to their understanding in the context of implementation possibilities in migrational public administration practice. It allows to determine the theories which should be used for Ukrainian state migration policy constructing and eliminating or reducing the external migration negative effects.

  4. Nonlinear dynamics and neo-piagetian theories in problem solving: perspectives on a new epistemology and theory development. (United States)

    Stamovlasis, Dimitrios


    In this study, an attempt is made to integrate Nonlinear Dynamical Systems theory and neo-Piagetian theories applied to creative mental processes, such as problem solving. A catastrophe theory model is proposed, which implements three neo-Piagetian constructs as controls: the functional M-capacity as asymmetry and logical thinking and the degree of field dependence independence as bifurcation. Data from achievement scores of students in tenth grade physics were analyzed using dynamic difference equations and statistical regression techniques. The cusp catastrophe model proved superior comparing to the pre-post linear counterpart and demonstrated nonlinearity at the behavioral level. The nonlinear phenomenology, such as hysteresis effects and bifurcation, is explained by an analysis, which provides a causal interpretation via the mathematical theory of self-organization and thus building bridges between NDS-theory concepts and neo-Piagetian theories. The contribution to theory building is made, by also addressing the emerging philosophical, - ontological and epistemological- questions about the processes of problem solving and creativity.

  6. From needs to goals and representations: Foundations for a unified theory of motivation, personality, and development. (United States)

    Dweck, Carol S


    Drawing on both classic and current approaches, I propose a theory that integrates motivation, personality, and development within one framework, using a common set of principles and mechanisms. The theory begins by specifying basic needs and by suggesting how, as people pursue need-fulfilling goals, they build mental representations of their experiences (beliefs, representations of emotions, and representations of action tendencies). I then show how these needs, goals, and representations can serve as the basis of both motivation and personality, and can help to integrate disparate views of personality. The article builds on this framework to provide a new perspective on development, particularly on the forces that propel development and the roles of nature and nurture. I argue throughout that the focus on representations provides an important entry point for change and growth. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  7. Development, implementation, and verification of multicycle depletion perturbation theory for reactor burnup analysis

    Energy Technology Data Exchange (ETDEWEB)

    White, J.R.


    A generalized depletion perturbation formulation based on the quasi-static method for solving realistic multicycle reactor depletion problems is developed and implemented within the VENTURE/BURNER modular code system. The present development extends the original formulation derived by M.L. Williams to include nuclide discontinuities such as fuel shuffling and discharge. This theory is first described in detail with particular emphasis given to the similarity of the forward and adjoint quasi-static burnup equations. The specific algorithm and computational methods utilized to solve the adjoint problem within the newly developed DEPTH (Depletion Perturbation Theory) module are then briefly discussed. Finally, the main features and computational accuracy of this new method are illustrated through its application to several representative reactor depletion problems.

  8. Developing skills learning in obstetric nursing: approaches between theory and practice. (United States)

    Lima, Maria de Fátima Gomes; Pequeno, Alice Maria Correia; Rodrigues, Dafne Paiva; Carneiro, Cleide; Morais, Ana Patrícia Pereira; Negreiros, Francisca Diana da Silva


    To analyze the development of professional skills in an obstetric nursing graduate course. Qualitative research, applying semi-structured interviews with 11 students in the obstetric nursing specialization at the State University of Ceará. Data was submitted to thematic review. According to the subjects, the course offers the development of skills to strengthen and expand the range of activities in obstetric nursing. Despite relying on previous knowledge and experience acquired by the students, there is a gap between the content taught and internship practice, presented as challenges and difficulties faced by the students. The findings suggest a need for curricular revision, incorporating active teaching-learning methodologies, to overcome the disjunction between theory and practice. Students are part of a corpus that is potentially implicated in the construction and transformation of thoughts and values set forth by educational and health institutions, and it is necessary to make changes in political and social organizations, with a focus on providing comprehensive and egalitarian care to the population. Analisar o desenvolvimento de competências profissionais em curso de pós-graduação em Enfermagem Obstétrica. Pesquisa qualitativa, utilizando entrevista semiestruturada com 11 egressos da especialização em Enfermagem Obstétrica da Universidade Estadual do Ceará. Dados submetidos à análise temática. Na ótica dos sujeitos, o curso confere o desenvolvimento de competências que fortalecem e ampliam o campo de atuação da enfermagem obstétrica. Embora resgate o conhecimento prévio dos discentes e as experiências vivenciadas, há distanciamento entre conteúdos ministrados e a prática de estágios, apresentados como desafios e dificuldades enfrentadas pelos egressos. Os achados sugerem revisão curricular, incorporando as metodologias ativas de ensino-aprendizagem, superando a fragmentação entre teoria e prática. Os egressos se constituem em um

  9. Personal construct psychology: a theory to help understand professional development, a philosophy to support it. (United States)

    Brocklehurst, Paul R


    The aim of this paper is to introduce the reader to personal construct psychology as a theory to help understand the process of change in facilitative and mentoring relationships. Continuing professional development is critical if practitioners are to keep up to date with new ideas, techniques, and materials. However, is it important not only to consider what is learnt, it is also important to understand the how of learning in order to develop an approach that leads to lifelong learning. Mentoring, coaching, and appraisal are all facilitative processes that aim to encourage professionals to engage with their own development. This leads to differing degrees of both behavioural and attitudinal change. As a result, it is useful to have a theory that can help an individual to understand these changes and to identify any difficulties that are associated with them. Personal construct psychology has long been recognised as a potential framework for personal development. It has been used extensively in a broad range of domains, including clinical and educational psychology, management, and psychotherapy. Personal construct psychology is a useful theory for understanding the facilitative process because it enables the facilitator to form a conceptual framework to comprehend behavioural and attitudinal change. Its underlying philosophical approach also supports lifelong learning, given its emphasis on an enquiring mind and reflection, both of which are key to continuing professional development.

  10. Language Theories Donation through Materials Development A case study in Jordan

    Directory of Open Access Journals (Sweden)

    Ali Ata Alkhaldi


    Full Text Available Materials development assists the teachers to understand and apply language learning theories and achieve professional development (Tomlinson, 2001 which this research has shown. This research aims to find out to what extent theories match the actual practice of materials and to help ‘theorists’ reflect upon language theories which are implicitly or explicitly embedded in the materials. It also aims to reveal the teachers’ and learners’ contributions in determining the practical theories. The sample of this research was purposive, that is, it was selected for a specific purpose to collect qualitative data and cover as wide a range as possible. The researcher interviewed thirty Jordanian teachers and students using qualitative research methods. The findings revealed some key principles donated by the participants, for example, 1 the materials should provide the learners with a variety of useful samples of discourse to enable them to use the language communicatively and meaningfully; 2 the materials should encourage the teachers’ and learners’ creativity; 3 the materials should take into account the teachers’ and learners’ preferences; and 4 the materials should take into consideration the specific and sensitive cultural aspects. Insightful implications and recommendations were suggested for future research.

  11. The evolution of an intervention--the use of Peplau's process of practice-based theory development. (United States)

    Peden, A R


    In 1969, at the first Nursing Theory Conference, Hildegard Peplau proposed a research methodology that would guide the development of nursing knowledge. To direct nurses in the development of practice-based theory, Peplau proposed a three-step process that would assist in this pursuit. The purpose of this paper is to describe the use of Peplau's process of practice-based theory development as it has directed a program of research in the area of depression. Peplau's ideas related to practice-based theory development came at a time in nursing when grand theories were being developed and theoretical nursing was highly valued. Peplau, ahead of her time, proposed an approach that valued the development of nursing knowledge in practice, while also combining both qualitative and quantitative methods. This research methodology deserves recognition today, as one that can guide knowledge development in psychiatric nursing.

  12. Lean and leadership practices: development of an initial realist program theory. (United States)

    Goodridge, Donna; Westhorp, Gill; Rotter, Thomas; Dobson, Roy; Bath, Brenna


    Lean as a management system has been increasingly adopted in health care settings in an effort to enhance quality, capacity and safety, while simultaneously containing or reducing costs. The Ministry of Health in the province of Saskatchewan, Canada has made a multi-million dollar investment in Lean initiatives to create "better health, better value, better care, and better teams", affording a unique opportunity to advance our understanding of the way in which Lean philosophy, principles and tools work in health care. In order to address the questions, "What changes in leadership practices are associated with the implementation of Lean?" and "When leadership practices change, how do the changed practices contribute to subsequent outcomes?", we used a qualitative, multi-stage approach to work towards developing an initial realist program theory. We describe the implications of realist assumptions for evaluation of this Lean initiative. Formal theories including Normalization Process Theory, Theories of Double Loop and Organization Leaning and the Theory of Cognitive Dissonance help understand this initial rough program theory. Data collection included: key informant consultation; a stakeholder workshop; documentary review; 26 audiotaped and transcribed interviews with health region personnel; and team discussions. A set of seven initial hypotheses regarding the manner in which Lean changes leadership practices were developed from our data. We hypothesized that Lean, as implemented in this particular setting, changes leadership practices in the following ways. Lean: a) aligns the aims and objectives of health regions; b) authorizes attention and resources to quality improvement and change management c) provides an integrated set of tools for particular tasks; d) changes leaders' attitudes or beliefs about appropriate leadership and management styles and behaviors; e) demands increased levels of expertise, accountability and commitment from leaders; f) measures and

  13. Health region development from the perspective of system theory - an empirical cross-regional case study. (United States)

    Volgger, Michael; Mainil, Tomas; Pechlaner, Harald; Mitas, Ondrej


    Governments are increasingly establishing health regions to deal with current challenges of public health service. These regions are seen as instruments to balance public and private stakeholders, and offer health care to regional citizens as well as to medical/health tourists. However, it is still unclear how the development of such health regions as well as their governance may be conceptualized. We apply Luhmann's system theory approach in the context of a cross-regional case study that compares health region developments in the Autonomous Province of Bolzano-South Tyrol (Italy) with particular regard to the Eastern Dolomites and in the province of Zeeland (the Netherlands). We suggest that Luhmann's system theory provides a useful set of criteria to evaluate and judge health region development. Fully developed health regions can be understood as auto-poietic systems. By emphasizing programs, personnel, and communication channels, these case studies illustrate the suitability of the system theory toolset to analyze the governance and spatial embeddedness of health regions. Additionally, the study contributes to literature by indicating that health regions are closely related to identity issues and to decision making in regions. Copyright © 2014 Elsevier Ltd.

  14. Building a multiple modality, theory-based physical activity intervention: The development of CardiACTION! (United States)

    Estabrooks, Paul A; Glasgow, Russ E; Xu, Stan; Dzewaltowski, David A; Lee, Rebecca E; Thomas, Deborah; Almeida, Fabio A; Thayer, Amy N; Smith-Ray, Renae L


    OBJECTIVES: Despite the widely acknowledged benefits of regular physical activity (PA), specific goals for increased population levels of PA, and strongly recommended strategies to promote PA, there is no evidence suggesting that the prevalence of PA is improving. If PA intervention research is to be improved, theory should be used as the basis for intervention development, participant context or environment should be considered in the process, and intervention characteristics that will heighten the likelihood of translation into practice should be implemented (e.g., ease of implementation, low human resource costs). The purpose of this paper is to describe the implementation of the aforementioned concepts within the intervention development process associated with CardiACTION an ongoing randomized 2 × 2 factorial trial. METHODS: The Ecological Model of Physical Activity integrated with Protection Motivation Theory was used to inform the design of the interventions. This integrated model was selected to allow for the development of theory-based individual, environmental, and individually + environmentally targeted physical activity interventions. All intervention strategies were matched to proposed mediators of behavior change. Strategies were then matched to the most appropriate interactive technology (i.e., interactive computer session, automated telephone counseling, and tailored mailings) delivery channel. CONCLUSIONS: The potential implications of this study include determining the independent and combined influence of individual and environment mechanisms of behavior change on intervention effectiveness. In addition, all intervention models are developed to be scalable and disseminable to a broad audience at a low cost.

  15. [Some problems with the development of the population theory since the founding of the People's Republic of China]. (United States)

    Feng, S X


    Since the founding of the People's Republic of China, the development of the population theory has experienced some setbacks. It is important to learn lessons from the past and establish a socialist population theory based on science. During the 1st 30 years of the People's Republic of China, the development of a population theory can be divided into 3 stages: 1) stage one was from 1949 to 1957 -- belief in population control on the basis of sociology; 2) stage two was from the late 1950s to early 1960s -- represented by Mr. Ma Yinchu's "New Population Theory" and the theory of the opposing side; and 3) stage Three began after the 1960s. Throughout the 1960s, studies of population theory remained stagnant, and no progress in this field was possible. In the 1970s, especially since the downfall of the "Gang of Four," the development of a population theory has entered a new stage. 3 problems with the development of the population theory discussed by the author are: 1) an evaluation of Comrade Mao Zedong's thoughts on population, 2) the division of different schools in population theory, 3) the different periods in the development of the population theory since 1949. Mao Zedong did change his thoughts on population control, but he was in favor of family planning and supported studies in population theory. Besides Ma Yinchu, Chin Da, Fei Xiaotong, Wu Jingchao and others also had their own population theories. The author emphasizes the contributions made by Mao Zedong and the Communist Party in the development of a population theory. New accomplishments and experience are expected with the downfall of the "Gang of Four."

  16. [Development of premature children: caregivers' understanding according to the Bioecological Theory]. (United States)

    Lemos, Rayla Amaral; Veríssimo, Maria de La Ó Ramallo


    Understanding the conceptions of premature children caregivers on child development and associated factors. An exploratory-descriptive qualitative study of 12 families with children under three years of age. Interviews were submitted to thematic content analysis, systematized into the categories of Bioecological Theory of Human Development: Process, Person, Context and Time, and in the Functional Development category. There are concerns about impairment in the current and future development of a Person/child defined as fragile as a result of premature birth (Time dimension), minimized by the scope of observable competencies such as motor skills. The Context, especially family and health services, and Proximal Processes, described as one-way caregiver interactions, are considered determinants of development. Functional Development is considered a natural consequence and result of education. The support network is crucial, supporting or limiting care. Concerns about the development mobilize caregivers to stimulate the premature child/person and requests family and healthcare assistance.

With the increased number of cesarean sections, the number of pregnancies with the previous cesarean section rises as well. The aim of this study was to establish the influence of the previous cesarean section on the development of placental complications: placenta previa, placental abruption and placenta accreta, as well as to determine the influence of the number of previous cesarean sections on the complic...

  18. Developing Scale for Assimilate the Integration between Learning Theories and E-learning.

    Directory of Open Access Journals (Sweden)

    George Maher Iskander


    Full Text Available As e-learning tend to get more and more significant for all kind of universities, researchers and consultants are becoming aware of the fact that a high technology approach and Blackboard do not guarantee successful teaching and learning. Thus, a move to pedagogy-based theories can be observed within the field of e-learning. This study describes the procedure of the development of an empirically-based psychometrically-sound instrument to measure instructional model for e-learning system at Middle East universities. In order to accelerate the acceptance of e-learning and implementation of institution-wide adoption of e-learning, it is important to understand students' perceptions with instructional model for e- learning. The 19-item scale developed shows a high probability of differentiating between positive and negative perceptions and the methods which can be used for embedding the traditional learning theories into e-learning.

  19. Gilbert Gottlieb's theory of probabilistic epigenesis: probabilities and realities in development. (United States)

    Valsiner, Jaan


    Gilbert Gottlieb's theory of probabilistic epigenesis is a fertile ground for further theoretical construction in developmental science. It fills in the gap in the domineering empiricism and honoring of inductive generalization that dominates psychology in the beginning of the 21st century, by offering a basic deductive framework for guiding the efforts of developmental science. It was based on a program of careful experimental investigations of the early avian ontogenies -- later to be generalized to the developmental processes as a generic phenomenon. Further development of his theory takes the form of (a) explicating the different meanings of probabilism in his model, and (b) extending his multi-level system to include psychological and social levels of organization. Gottlieb's contribution allows for a new synthesis of contemporary epigenetics and developmental science, and sets up major challenges for the methodology of research on development.

  20. Applications of Dynamic Systems Theory to Cognition and Development: New Frontiers. (United States)

    Perone, S; Simmering, V R


    A central goal in developmental science is to explain the emergence of new behavioral forms. Researchers consider potential sources of behavioral change depending partly on their theoretical perspective. This chapter reviews one perspective, dynamic systems theory, which emphasizes the interactions among multiple components to drive behavior and developmental change. To illustrate the central concepts of dynamic systems theory, we describe empirical and computational studies from a range of domains, including motor development, the Piagetian A-not-B task, infant visual recognition, visual working memory capacity, and language learning. We conclude by advocating for a broader application of dynamic systems approaches to understanding cognitive and behavioral development, laying out the remaining barriers we see and suggested ways to overcome them. © 2017 Elsevier Inc.

  1. Developing a grounded theory approach: a comparison of Glaser and Strauss. (United States)

    Heath, Helen; Cowley, Sarah


    Novice qualitative researchers are often unsure regarding the analysis of their data and, where grounded theory is chosen, they may be uncertain regarding the differences that now exist between the approaches of Glaser and Strauss, who together first described the method. These two approaches are compared in relation to roots and divergences, role of induction, deduction and verification, ways in which data are coded and the format of generated theory. Personal experience of developing as a ground theorist is used to illustrate some of the key differences. A conclusion is drawn that, rather than debate relative merits of the two approaches, suggests that novice researchers need to select the method that best suits their cognitive style and develop analytic skills through doing research.

  2. Adolescent Peer Relations and Socioemotional Development in Latin America: Translating International Theory into Local Research. (United States)

    Berger, Christian; Lisboa, Carolina; Cuadros, Olga; de Tezanos-Pinto, Pablo


    Peer relations constitute a main developmental context for adolescents. Peers offer an instance for identity definition and set the norms of acceptable and valued characteristics, behaviors, and attitudes, representing a societal model that allows and restrains avenues for adolescents' socioemotional development. The present article departs from these considerations to review research on adolescents' peer relations in Latin America from a socioemotional perspective. First, approaches to adolescence are discussed, with a main focus on attachment and identity theories, based on a bioecological framework. Then, a review of research in Latin America on friendships, school climate, and intergroup relations is presented. The discussion addresses the tension between theories and evidence generated in developed societies and highlights the particularities of Latin American youth, stressing the need for collecting local data. © 2016 Wiley Periodicals, Inc.

  3. Facilitating progress in health behaviour theory development and modification: the reasoned action approach as a case study. (United States)

    Head, Katharine J; Noar, Seth M


    This paper explores the question: what are barriers to health behaviour theory development and modification, and what potential solutions can be proposed? Using the reasoned action approach (RAA) as a case study, four areas of theory development were examined: (1) the theoretical domain of a theory; (2) tension between generalisability and utility, (3) criteria for adding/removing variables in a theory, and (4) organisational tracking of theoretical developments and formal changes to theory. Based on a discussion of these four issues, recommendations for theory development are presented, including: (1) the theoretical domain for theories such as RAA should be clarified; (2) when there is tension between generalisability and utility, utility should be given preference given the applied nature of the health behaviour field; (3) variables should be formally removed/amended/added to a theory based on their performance across multiple studies and (4) organisations and researchers with a stake in particular health areas may be best suited for tracking the literature on behaviour-specific theories and making refinements to theory, based on a consensus approach. Overall, enhancing research in this area can provide important insights for more accurately understanding health behaviours and thus producing work that leads to more effective health behaviour change interventions.

    Shahaeian, Ameneh; Peterson, Candida C.; Slaughter, Virginia; Wellman, Henry M.


    To examine cultural contrasts in the ordered sequence of conceptual developments leading to theory of mind (ToM), we compared 135 3- to 6-year-olds (77 Australians; 58 Iranians) on an established 5-step ToM scale (Wellman & Liu, 2004). There was a cross-cultural difference in the sequencing of ToM steps but not in overall rates of ToM mastery.…

  8. Development of a program theory for shared decision-making: a realist review protocol. (United States)

    Groot, Gary; Waldron, Tamara; Carr, Tracey; McMullen, Linda; Bandura, Lori-Ann; Neufeld, Shelley-May; Duncan, Vicky


    The practicality of applying evidence to healthcare systems with the aim of implementing change is an ongoing challenge for practitioners, policy makers, and academics. Shared decision- making (SDM), a method of medical decision-making that allows a balanced relationship between patients, physicians, and other key players in the medical decision process, is purported to improve patient and system outcomes. Despite the oft-mentioned benefits, there are gaps in the current literature between theory and implementation that would benefit from a realist approach given the value of this methodology to analyze complex interventions. In this protocol, we outline a study that will explore: "In which situations, how, why, and for whom does SDM between patients and health care providers contribute to improved decision making?" A seven step iterative process will be described including preliminary theory development, establishment of a search strategy, selection and appraisal of literature, data extraction, analysis and synthesis of extracted results from literature, and formation of a revised program theory with the input of patients, physicians, nurse navigators, and policy makers from a stakeholder session. The goal of the realist review will be to identify and refine a program theory for SDM through the identification of mechanisms which shape the characteristics of when, how, and why SDM will, and will not, work.

  9. Action mechanisms for social cognition: behavioral and neural correlates of developing Theory of Mind (United States)

    Bowman, Lindsay C.; Thorpe, Samuel G.; Cannon, Erin N.; Fox, Nathan A.


    Many psychological theories posit foundational links between two fundamental constructs: (1) our ability to produce, perceive, and represent action; and (2) our ability to understand the meaning and motivation behind the action (i.e. Theory of Mind; ToM). This position is contentious, however, and long-standing competing theories of social-cognitive development debate roles for basic action-processing in ToM. Developmental research is key to investigating these hypotheses, but whether individual differences in neural and behavioral measures of motor action relate to social-cognitive development is unknown. We examined 3- to 5-year-old children’s (N = 26) EEG mu-desynchronization during production of object-directed action, and explored associations between mu-desynchronization and children’s behavioral motor skills, behavioral action-representation abilities, and behavioral ToM. For children with high (but not low) mu-desynchronization, motor skill related to action-representation abilities, and action-representation mediated relations between motor skill and ToM. Results demonstrate novel foundational links between action-processing and ToM, suggesting that basic motor action may be a key mechanism for social-cognitive development, thus shedding light on the origins and emergence of higher social cognition.

    DEFF Research Database (Denmark)

    Carl, Michael; Schaeffer, Moritz


    Initial versions of the translation process research database (TPR-DB), were released around 2011 in an attempt to integrate translation process data from several until then individually collected and scattered translation research projects. While the earlier individual studies had a clear focus ...... and used in qualitative research in social science ad many other research areas.

  11. Development of the applied mathematics originating from the group theory of physical and mathematical problems

    Energy Technology Data Exchange (ETDEWEB)

    Hyman, J.; Beyer, W.; Louck, J.; Metropolis, N.


    This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Group theoretical methods are a powerful tool both in their applications to mathematics and to physics. The broad goal of this project was to use such methods to develop the implications of group (symmetry) structures underlying models of physical systems, as well as to broaden the understanding of simple models of chaotic systems. The main thrust was to develop further the complex mathematics that enters into many-particle quantum systems with special emphasis on the new directions in applied mathematics that have emerged and continue to surface in these studies. In this area, significant advances in understanding the role of SU(2) 3nj-coefficients in SU(3) theory have been made and in using combinatoric techniques in the study of generalized Schur functions, discovered during this project. In the context of chaos, the study of maps of the interval and the associated theory of words has led to significant discoveries in Galois group theory, to the classification of fixed points, and to the solution of a problem in the classification of DNA sequences.

I find his value theory promising but still a mere sketch rather than an actual general......Jean Baudrillard outlined a theory of value in his early writings that built on, but also criticized, Marxist concepts of use value and exchange value.

  13. Informing Patients About Placebo Effects: Using Evidence, Theory, and Qualitative Methods to Develop a New Website. (United States)

    Greville-Harris, Maddy; Bostock, Jennifer; Din, Amy; Graham, Cynthia A; Lewith, George; Liossi, Christina; O'Riordan, Tim; White, Peter; Yardley, Lucy; Bishop, Felicity L


    According to established ethical principles and guidelines, patients in clinical trials should be fully informed about the interventions they might receive. However, information about placebo-controlled clinical trials typically focuses on the new intervention being tested and provides limited and at times misleading information about placebos. We aimed to create an informative, scientifically accurate, and engaging website that could be used to improve understanding of placebo effects among patients who might be considering taking part in a placebo-controlled clinical trial. Our approach drew on evidence-, theory-, and person-based intervention development. We used existing evidence and theory about placebo effects to develop content that was scientifically accurate. We used existing evidence and theory of health behavior to ensure our content would be communicated persuasively, to an audience who might currently be ignorant or misinformed about placebo effects. A qualitative 'think aloud' study was conducted in which 10 participants viewed prototypes of the website and spoke their thoughts out loud in the presence of a researcher. The website provides information about 10 key topics and uses text, evidence summaries, quizzes, audio clips of patients' stories, and a short film to convey key messages. Comments from participants in the think aloud study highlighted occasional misunderstandings and off-putting/confusing features. These were addressed by modifying elements of content, style, and navigation to improve participants' experiences of using the website. We have developed an evidence-based website that incorporates theory-based techniques to inform members of the public about placebos and placebo effects. Qualitative research ensured our website was engaging and convincing for our target audience who might not perceive a need to learn about placebo effects. Before using the website in clinical trials, it is necessary to test its effects on key outcomes

  14. Leadership styles and theories. (United States)

    Giltinane, Charlotte Louise

    It is useful for healthcare professionals to be able to identify the leadership styles and theories relevant to their nursing practice. Being adept in recognising these styles enables nurses to develop their skills to become better leaders, as well as improving relationships with colleagues and other leaders, who have previously been challenging to work with. This article explores different leadership styles and theories, and explains how they relate to nursing practice.

  15. Theory of communicative action: a basis for the development of critical thinking. (United States)

    Carvalho, Diana Paula de Souza Rego Pinto; Vitor, Allyne Fortes; Cogo, Ana Luísa Petersen; Santos, Viviane Euzébia Pereira; Ferreira, Marcos Antonio


    Reflections on some assumptions of the theory of Communicative Action and the development of Critical Thinking in the context of training students in undergraduate nursing courses. The perspective is based on concepts of Jürgen Habermas, as a possibility for the development of critical thinking among the students of these courses. Communication is therefore understood as inherent in the training of nurses in a continuous, dynamic, dialogical process, with interventions that are related to the context of the students and that have meaning for them, in order to contribute to the promotion of Critical Thinking.

  19. Owner response to companion animal death: development of a theory and practical implications. (United States)

    Adams, C L; Bonnett, B N; Meek, A H


    This study used an inductive research method known as grounded theory to develop a theory to describe owner response to the death of a pet. Participants were identified from 8 veterinary clinics in Wellington Country, Ontario. Eighty percent (8 of 10) of the practices approached agreed to participate and there was a 77% (44 of 57) participation rate by clients. Nondirective interviews were conducted with participants approximately 10 days following the death of their pet, and at 3, 6, and 12 mo thereafter. The theory developed suggests that people's reactions are best described as a social and psychological search for meaning. Factors that contributed to the search for meaning included societal values and norms, the cultural milieu of pet death, and the cultural milieu of veterinary medicine. Other factors, such as the participant's personal beliefs, life stage, critical life events, and animal attributes, either alleviated or aggravated the experience. The outcome for participants grieving the death of a pet was a self-governing approach to coping with the death. Practical implications and suggestions for veterinarians are presented.

  20. [Health promotion. Instrument development for the application of the theory of planned behavior]. (United States)

    Lee, Y O


    The purpose of this article is to describe operationalization of the Theory of Planned Behavior (TPB). The quest to understand determinants of health behaviors has intensified as evidence accumulates concerning the impact of personal behavior on health. The majority of theory-based research has used the Health Belief Model(HBM). The HBM components have had limited success in explaining health-related behaviors. There are several advantages of the TPB over the HBM. TPB is an expansion of the Theory of Reasoned Action(TRA) with the addition of the construct, perceived behavioral control. The revised model has been shown to yield greater explanatory power than the original TRA for goal-directed behaviors. The process of TPB instrument development was described, using example form the study of smoking cessation behavior in military smokers. It was followed by a discussion of reliability and validity issues in operationalizing the TPB. The TPB is a useful model for understanding and predicting health-related behaviors when carefully operationalized. The model holds promise in the development of prescriptive nursing approaches.

  1. The nutrition for sport knowledge questionnaire (NSKQ): development and validation using classical test theory and Rasch analysis. (United States)

    Trakman, Gina Louise; Forsyth, Adrienne; Hoye, Russell; Belski, Regina


    Appropriate dietary intake can have a significant influence on athletic performance. There is a growing consensus on sports nutrition and professionals working with athletes often provide dietary education. However, due to the limitations of existing sports nutrition knowledge questionnaires, previous reports of athletes' nutrition knowledge may be inaccurate. An updated questionnaire has been developed based on a recent review of sports nutrition guidelines. The tool has been validated using a robust methodology that incorporates relevant techniques from classical test theory (CTT) and Item response theory (IRT), namely, Rasch analysis. The final questionnaire has 89 questions and six sub-sections (weight management, macronutrients, micronutrients, sports nutrition, supplements, and alcohol). The content and face validity of the tool have been confirmed based on feedback from expert sports dietitians and university sports students, respectively. The internal reliability of the questionnaire as a whole is high (KR = 0.88), and most sub-sections achieved an acceptable internal reliability. Construct validity has been confirmed, with an independent T-test revealing a significant ( p  < 0.001) difference in knowledge scores of nutrition (64 ± 16%) and non-nutrition students (51 ± 19%). Test-retest reliability has been assured, with a strong correlation ( r  = 0.92, p  < 0.001) between individuals' scores on two attempts of the test, 10 days to 2 weeks apart. Three of the sub-sections fit the Rasch Unidimensional Model. The final version of the questionnaire represents a significant improvement over previous tools. Each nutrition sub-section is unidimensional, and therefore researchers and practitioners can use these individually, as required. Use of the questionnaire will allow researchers to draw conclusions about the effectiveness of nutrition education programs, and differences in knowledge across athletes of varying ages, genders, and athletic

  2. String theory and the path to unification: A review of recent developments (United States)

    Dienes, Keith R.


    This is a pedagogical review article surveying the various approaches towards understanding gauge coupling unification within string theory. As is well known, one of the major problems confronting string phenomenology has been an apparent discrepancy between the scale of gauge coupling unification predicted within string theory, and the unification scale expected within the framework of the Minimal Supersymmetric Standard Model (MSSM). In this article, I provide an overview of the different approaches that have been taken in recent years towards reconciling these two scales, and outline some of the major recent developments in each. These approaches include string GUT models; higher affine levels and non-standard hypercharge normalizations; heavy string threshold corrections; light supersymmetric thresholds; effects from intermediate-scale gauge and matter structure beyond the MSSM; strings without supersymmetry; and strings at strong coupling.

  3. Neutral theory and the species abundance distribution: recent developments and prospects for unifying niche and neutral perspectives (United States)

    Matthews, Thomas J; Whittaker, Robert J


    Published in 2001, The Unified Neutral Theory of Biodiversity and Biogeography (UNTB) emphasizes the importance of stochastic processes in ecological community structure, and has challenged the traditional niche-based view of ecology. While neutral models have since been applied to a broad range of ecological and macroecological phenomena, the majority of research relating to neutral theory has focused exclusively on the species abundance distribution (SAD). Here, we synthesize the large body of work on neutral theory in the context of the species abundance distribution, with a particular focus on integrating ideas from neutral theory with traditional niche theory. First, we summarize the basic tenets of neutral theory; both in general and in the context of SADs. Second, we explore the issues associated with neutral theory and the SAD, such as complications with fitting and model comparison, the underlying assumptions of neutral models, and the difficultly of linking pattern to process. Third, we highlight the advances in understanding of SADs that have resulted from neutral theory and models. Finally, we focus consideration on recent developments aimed at unifying neutral- and niche-based approaches to ecology, with a particular emphasis on what this means for SAD theory, embracing, for instance, ideas of emergent neutrality and stochastic niche theory. We put forward the argument that the prospect of the unification of niche and neutral perspectives represents one of the most promising future avenues of neutral theory research. PMID:25360266

    Full Text Available Local governance is a broad concept and is defined as the formulation and execution of collective action at the local level. The purpose of local government is to ensure effective and efficient use of public resources and service delivery at the level closest to citizens. Regional development is a new concept that aims to stimulate and diversify the economic activity of a country (region, to encourage investment in the private sector, to create a new jobs vacancy and improves living standards of the country. Regional development policies are a number of measures designed and promoted by the central and local administration, but the cooperation undertaken at the actors are in a different one, which included the private sector and civil society. At the center of these regional policies or practices is the use of efficient potential of each region, being particularly focused on business, means promoting the development of the new enterprises, promoting labor market and investment, improve the quality of environment, health , education and culture. Traditional objective of regional development policies is the reduction of territorial disparities for achieving a relative balance between economic and social levels of development in different areas in the national territory. Regional development is the actual task of local government units in Albania, and is one of the tasks and challenges of the future. Currently it takes a special importance in the context of European Union integration. Reforms have begun to change the system in 1990 in order to implement local democracy and decentralization principles that are present today. Inequalities that exist within the region and between them indicate that in some regions the economic potential is not being fully utilized, and that it reduces the overall performance in national level.

  5. Towards a Theory Grounded Theory of Language


    Prince, Christopher G.; Mislivec, Eric J.; Kosolapov, Oleksandr V.; Lykken, Troy R.


    In this paper, we build upon the idea of theory grounding and propose one specific form of theory grounding, a theory of language. Theory grounding is the idea that we can imbue our embodied artificially intelligent systems with theories by modeling the way humans, and specifically young children, develop skills with theories. Modeling theory development promises to increase the conceptual and behavioral flexibility of these systems. An example of theory development in children is the social ...

  7. Development of the Theory of Capitalist Crises: Political Economy Traditions and Modernity

    Directory of Open Access Journals (Sweden)

    Viktor Timofeyevich Ryazanov


    Full Text Available The article discusses the development history of the theory of economic crises under capitalism conditions. The author believes that economic science is being developed in two directions. The first direction is represented by science schools that deny any objective grounds for crises of overproduction in the market economy and develop new models of crisis-free growth. The opposite direction is supported by science schools acknowledging the existence of objective causes of crises, which is of practical significance for development of effective anti-crisis measures. The study is summarized by the conclusion about actualization of the political economy approach to analysis of the recent global crisis and its consequences. Its implementation anticipates special attention to different versions of overaccumulation of capital which played a key role in the origin of crisis processes in the world economy.

  8. The Role of Adolescent Development in Social Networking Site Use: Theory and Evidence

    Directory of Open Access Journals (Sweden)

    Drew P. Cingel


    Full Text Available Using survey data collected from 260 children, adolescents, and young adults between the ages of 9 and 26, this paper offers evidence for a relationship between social networking site use and Imaginary Audience, a developmental variable in which adolescents believe others are thinking about them at all times. Specifically, after controlling for a number of variables, results indicate a significant, positive relationship between social networking site use and Imaginary Audience ideation. Additionally, results indicate a positive relationship between Imaginary Audience ideation and Facebook customization practices. Together, these findings provide evidence, based on Vygotskian developmental theory, for a general consideration of the role that currently available tools, in this case social networking sites, can have on development. Thus, findings implicate both the role of development on social networking site use, as well as the role of social networking site use on development. Overall, these findings have important implications for the study of media and human development, which are discussed in detail.

    Full Text Available Development is very present in speeches, discussions and studies by different institutions and an area that is gaining ground is the regional development. From this observation, we sought to identify the presence of theoretical preconditions that influence the development of a region, taking as reference the theories of the export basis and growth poles. The chosen area was the Association of Municipalities of West Santa Catarina - AMOSC - that parts from West Santa Catarina, known by the presence of meat (poultry and pigs processing agribusiness. Its effective occupation occurred after the arrival of immigrants from Rio Grande do Sul and market-oriented economic activities began with the timber and, subsequently, with diversified agricultural production, carried out on small rural properties. The business capital was the basis for the implementation of refrigerators for the processing of meat and swine products and the expansion of agribusiness occurred from the integration with the farmers who supplied the raw material for the industry. Regarding the theories analyzed, it was found that the agribusiness of meat processing and meat products played the role of industry-driving; in other words, boosted the development of other activities and industries. Agribusiness also represents the export basis, which promoted the economic expansion of AMOSC.

  10. On the theory of social innovations: Tarde's neglected contribution to the development of a sociological innovation theory


    Howaldt, Jürgen; Kopp, Ralf; Schwarz, Michael


    The term 'social innovation' is currently becoming increasingly significant in social and political discourse. However, so far there is still no theoretically grounded, practicable concept of social innovation. Through recourse to the social theory of Gabriel Tarde, with its focus on social inventions and social practices of imitation, social innovation can be identified as a specific mechanism of change, and hence the analytical perspective can be directed towards society as a locus of innov...

  11. Women in construction management: Creating a theory of career choice and development (United States)

    Moore, Jennifer Dawn


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

  12. The applicability of a seminal professional development theory to creative arts therapies students. (United States)

    Orkibi, Hod


    The purpose of this mixed-methods study was to test the extent to which a seminal theory of the professional development of counsellors and therapists is applicable to the particular experiences of creative arts therapies graduate students who learn how to use the arts in psychotherapy. Nevertheless, readers may consider the results of the present study transferable to other healthcare disciplines. Questionnaires for each developmental phase were used for data collection, and analysis included data quantification, assessment of inter-rater agreement and theory derivation procedure. Results indicate that creative arts therapies students were concerned about translating theory into practice, learning how experienced therapists concretely function in practice, and reducing cognitive dissonance upon realization that their pre-training lay conceptions of helping were no longer valid. Stress and anxiety drove students to adopt easily mastered techniques that were implemented creatively in practicum. The results confirm that students who were older and had undergraduate human-service education and/or considerable life experience were less concerned about their suitability to the profession, were more acquainted with a professional working style and searched for their individual way of becoming therapists. Finally, recommendations for future research are suggested, and implications for practice are offered. Copyright © 2013 John Wiley & Sons, Ltd.

  13. Theory of Mind Development in Adolescence and Early Adulthood: The Growing Complexity of Recursive Thinking Ability (United States)

    Valle, Annalisa; Massaro, Davide; Castelli, Ilaria; Marchetti, Antonella


    This study explores the development of theory of mind, operationalized as recursive thinking ability, from adolescence to early adulthood (N = 110; young adolescents = 47; adolescents = 43; young adults = 20). The construct of theory of mind has been operationalized in two different ways: as the ability to recognize the correct mental state of a character, and as the ability to attribute the correct mental state in order to predict the character’s behaviour. The Imposing Memory Task, with five recursive thinking levels, and a third-order false-belief task with three recursive thinking levels (devised for this study) have been used. The relationship among working memory, executive functions, and linguistic skills are also analysed. Results show that subjects exhibit less understanding of elevated recursive thinking levels (third, fourth, and fifth) compared to the first and second levels. Working memory is correlated with total recursive thinking, whereas performance on the linguistic comprehension task is related to third level recursive thinking in both theory of mind tasks. An effect of age on third-order false-belief task performance was also found. A key finding of the present study is that the third-order false-belief task shows significant age differences in the application of recursive thinking that involves the prediction of others’ behaviour. In contrast, such an age effect is not observed in the Imposing Memory Task. These results may support the extension of the investigation of the third order false belief after childhood.

  14. Developing Theory to Guide Building Practitioners' Capacity to Implement Evidence-Based Interventions. (United States)

    Leeman, Jennifer; Calancie, Larissa; Kegler, Michelle C; Escoffery, Cam T; Herrmann, Alison K; Thatcher, Esther; Hartman, Marieke A; Fernandez, Maria E


    Public health and other community-based practitioners have access to a growing number of evidence-based interventions (EBIs), and yet EBIs continue to be underused. One reason for this underuse is that practitioners often lack the capacity (knowledge, skills, and motivation) to select, adapt, and implement EBIs. Training, technical assistance, and other capacity-building strategies can be effective at increasing EBI adoption and implementation. However, little is known about how to design capacity-building strategies or tailor them to differences in capacity required across varying EBIs and practice contexts. To address this need, we conducted a scoping study of frameworks and theories detailing variations in EBIs or practice contexts and how to tailor capacity-building to address those variations. Using an iterative process, we consolidated constructs and propositions across 24 frameworks and developed a beginning theory to describe salient variations in EBIs (complexity and uncertainty) and practice contexts (decision-making structure, general capacity to innovate, resource and values fit with EBI, and unity vs. polarization of stakeholder support). The theory also includes propositions for tailoring capacity-building strategies to address salient variations. To have wide-reaching and lasting impact, the dissemination of EBIs needs to be coupled with strategies that build practitioners' capacity to adopt and implement a variety of EBIs across diverse practice contexts.

  15. Evaluation utilization research--developing a theory and putting it to use. (United States)

    Neuman, Ari; Shahor, Neria; Shina, Ilan; Sarid, Anat; Saar, Zehava


    This article presents the findings of a two-stage study that had two key objectives: to develop a theory about evaluation utilization in an educational organization and to apply this theory to promote evaluation utilization within the organization. The first stage involved a theoretical conceptualization using a participatory method of concept mapping. This process identified the modes of evaluation utilization within the organization, produced a representation of the relationship between them and led to a theory. The second stage examined the practical implications of this conceptualization in terms of how different stakeholders in the organization perceive the actual and preferable state of evaluation utilization within the organization (i.e. to what extent is evaluation utilized and to what extent should it be utilized). The participatory process of the study promoted the evaluation utilization by involving stakeholders, thus giving them a sense of ownership and improving communication between the evaluation unit and the stakeholders. In addition, understanding the evaluation needs of the stakeholders in the organization helped generate relevant and realizable evaluation processes. On a practical level, the results are currently shaping the evaluation plan and the place of evaluations within the organization. Copyright © 2012 Elsevier Ltd. All rights reserved.

  16. Developing a theory of the strategic core of teams: a role composition model of team performance. (United States)

    Humphrey, Stephen E; Morgeson, Frederick P; Mannor, Michael J


    Although numerous models of team performance have been articulated over the past 20 years, these models have primarily focused on the individual attribute approach to team composition. The authors utilized a role composition approach, which investigates how the characteristics of a set of role holders impact team effectiveness, to develop a theory of the strategic core of teams. Their theory suggests that certain team roles are most important for team performance and that the characteristics of the role holders in the "core" of the team are more important for overall team performance. This theory was tested in 778 teams drawn from 29 years of major league baseball (1974'-2002). Results demonstrate that although high levels of experience and job-related skill are important predictors of team performance, the relationships between these constructs and team performance are significantly stronger when the characteristics are possessed by core role holders (as opposed to non-core role holders). Further, teams that invest more of their financial resources in these core roles are able to leverage such investments into significantly improved performance. These results have implications for team composition models, as they suggest a new method for considering individual contributions to a team's success that shifts the focus onto core roles.

  17. Development and psychometric validation of social cognitive theory scales in an oral health context. (United States)

    Jones, Kelly; Parker, Eleanor J; Steffens, Margaret A; Logan, Richard M; Brennan, David; Jamieson, Lisa M


    This study aimed to develop and evaluate scales reflecting potentially modifiable social cognitive theory-based risk indicators associated with homeless populations' oral health. The scales are referred to as the social cognitive theory risk scales in an oral health context (SCTOH) and are referred to as SCTOH(SE), SCTOH(K) and SCTOH(F), respectively. The three SCTOH scales assess the key constructs of social cognitive theory: self-efficacy, knowledge and fatalism. The reliability and validity of the three scales were evaluated in a convenience sample of 248 homeless participants (age range 17-78 years, 79% male) located in a metropolitan setting in Australia. The scales were supported by exploratory factor analysis and established three distinct and internally consistent domains of social cognition: oral health-related self-efficacy, oral health-related knowledge and oral health-related fatalism, with Cronbach's alphas of 0.95, 0.85 and Spearman's-Brown ρ of 0.69. Concurrent ability was confirmed by each SCTOH scale's association with oral health status in the expected directions. The three SCTOH scales appear to be internally valid and reliable. If confirmed by further research, these scales could potentially be used for tailored educational and cognitive-behavioural interventions to reduce oral health inequalities among homeless and other vulnerable populations. © 2015 Public Health Association of Australia.

The physical principles underlying string theory are also outlined. (U.K.)

  19. The systematic development of a brief intervention to increase walking in the general public using an "extended" theory of planned behavior. (United States)

    French, David P; Darker, Catherine D; Eves, Frank F; Sniehotta, Falko F


    The Theory of Planned Behavior (TPB) has been extensively used in predictive studies, but there have been considerably fewer experimental tests of the theory. One reason for this is that the guidance on developing concrete intervention strategies from the abstract theory is vague, and there are few exemplars of how to do this. The aim of this article is to provide such an exemplar. The development of an intervention to increase walking in the general public is described, based on the TPB, extended to include postvolitional processes. Identification of target constructs, elicitation of key salient beliefs underpinning these constructs, selection of appropriate behavior change techniques, and technique refinement. Each step is based on available evidence and consistent with theory. Perceived behavioral control (PBC) was identified as the key determinant of walking intentions, with an "intention-behavior gap" noted. A brief intervention was developed, using techniques to increase PBC by rehearsal of previous successful performance of behavior, along with planning techniques to translate motivation into behavior. This systematic approach taken should provide a model for others. The intervention has demonstrated efficacy in producing large changes in objectively measured walking behavior, in 2 separate evaluations reported elsewhere.

  2. Processability Theory and the Role of Morphology in English as a Second Language Development: A Longitudinal Study (United States)

    Dyson, Bronwen


    This article tests a prediction made by Processability Theory (Pienemann, 1998; 2005) that morphological acquisition is the driving force in English as a second language (ESL) development. It first outlines the model of psycholinguistic processing assumed by Processability Theory and shows how stages fall out from it. It then presents the…

  3. Generating or developing grounded theory: methods to understand health and illness. (United States)

    Woods, Phillip; Gapp, Rod; King, Michelle A


    Grounded theory is a qualitative research methodology that aims to explain social phenomena, e.g. why particular motivations or patterns of behaviour occur, at a conceptual level. Developed in the 1960s by Glaser and Strauss, the methodology has been reinterpreted by Strauss and Corbin in more recent times, resulting in different schools of thought. Differences arise from different philosophical perspectives concerning knowledge (epistemology) and the nature of reality (ontology), demanding that researchers make clear theoretical choices at the commencement of their research when choosing this methodology. Compared to other qualitative methods it has ability to achieve understanding of, rather than simply describing, a social phenomenon. Achieving understanding however, requires theoretical sampling to choose interviewees that can contribute most to the research and understanding of the phenomenon, and constant comparison of interviews to evaluate the same event or process in different settings or situations. Sampling continues until conceptual saturation is reached, i.e. when no new concepts emerge from the data. Data analysis focusses on categorising data (finding the main elements of what is occurring and why), and describing those categories in terms of properties (conceptual characteristics that define the category and give meaning) and dimensions (the variations within properties which produce specificity and range). Ultimately a core category which theoretically explains how all other categories are linked together is developed from the data. While achieving theoretical abstraction in the core category, it should be logical and capture all of the variation within the data. Theory development requires understanding of the methodology not just working through a set of procedures. This article provides a basic overview, set in the literature surrounding grounded theory, for those wanting to increase their understanding and quality of research output.

  4. String theory or field theory?

    International Nuclear Information System (INIS)

    Marshakov, A.V.


    The status of string theory is reviewed, and major recent developments - especially those in going beyond perturbation theory in the string theory and quantum field theory frameworks - are analyzed. This analysis helps better understand the role and place of experimental phenomena, it is emphasized that there are some insurmountable problems inherent in it - notably the impossibility to formulate the quantum theory of gravity on its basis - which prevent it from being a fundamental physical theory of the world of microscopic distances. It is this task, the creation of such a theory, which string theory, currently far from completion, is expected to solve. In spite of its somewhat vague current form, string theory has already led to a number of serious results and greatly contributed to progress in the understanding of quantum field theory. It is these developments, which are our concern in this review [ru

  5. Development of analytical theory of the physical libration for a two-layer Moon (United States)

    Petrova, Natalia; Barkin, Yurii; Gusev, Alexander; Ivanova, Tamara


    Investigation is being carried out in the frame of Russian-Japanese grant and directed onto providing of the future observations in the frame of the ILOM-project which is planned onto the end of the second decade. The analytical theory presents both scientific interest in its own right and can be useful as a base for the lunar annual in a future, as a clue to lunar interiors and to processes inside the lunar body. A comparison of the libration's analytical theory with new observations will allow to refine the parameters of lunar interiors: an existence or absence of a core, its size, composition and state of aggregation, Love numbers, qualitative parameter Q, etc. Contrary to the usual application of numerical libration models for analyses of observations, the analytical model is able to predict the new harmonics, early unknown and not observed (owing to the insufficient accuracy of observations) in libration's series of observations. As part of the investigation the following results were achieved. Development of the analytical theory of the Lunar Physical Libration (LPhL) were performed using the Poisson Series Processor (PSP). The base solution is realized for the 'main problem' of the LPhL in view of 4-th harmonic of selenopotential. Data on a dynamical figure of the Moon are incorporated in the theory on the basis of new observations of the Lunar gravitational field, received in a frame of space projects Clementine (1994, NASA), Lunar Prospector (1999, NASA) and the SELENE (2007 - 2009, Japan). On the basis of the constructed theory the following actions were done: 1) analyses of the present dynamical models; 2) modeling of stars trajectories in the field of view of the future optical telescope, which is planned to be placed on one of the Lunar poles in the second stage of the Japanese project SELENE-B - ILOM. Results of modeling have shown opportunities of determination of LPhL-parameters with the desirable accuracy 0.001 arc seconds planned in the ILOM

  8. Integrating design science theory and methods to improve the development and evaluation of health communication programs. (United States)

    Neuhauser, Linda; Kreps, Gary L


    Traditional communication theory and research methods provide valuable guidance about designing and evaluating health communication programs. However, efforts to use health communication programs to educate, motivate, and support people to adopt healthy behaviors often fail to meet the desired goals. One reason for this failure is that health promotion issues are complex, changeable, and highly related to the specific needs and contexts of the intended audiences. It is a daunting challenge to effectively influence health behaviors, particularly culturally learned and reinforced behaviors concerning lifestyle factors related to diet, exercise, and substance (such as alcohol and tobacco) use. Too often, program development and evaluation are not adequately linked to provide rapid feedback to health communication program developers so that important revisions can be made to design the most relevant and personally motivating health communication programs for specific audiences. Design science theory and methods commonly used in engineering, computer science, and other fields can address such program and evaluation weaknesses. Design science researchers study human-created programs using tightly connected build-and-evaluate loops in which they use intensive participatory methods to understand problems and develop solutions concurrently and throughout the duration of the program. Such thinking and strategies are especially relevant to address complex health communication issues. In this article, the authors explore the history, scientific foundation, methods, and applications of design science and its potential to enhance health communication programs and their evaluation.

  9. Early Childhood Professional Development: An Experimental Study of Adult Teaching Practices Derived from Adult Learning Theory (United States)

    Weber-Mayrer, Melissa M.

    Research that describes how adults acquire and use new information, collectively called adult learning theory, has potentially important implications for facilitating such adult learning experiences as educator professional development. The purpose of this study was to examine whether integrating adult teaching practices derived from adult learning theories into early childhood educators professional development would result in better gains in educator engagement in professional development, phonological awareness abilities, phonological awareness knowledge, and language and literacy beliefs. The impact on educator engagement and educator proximal knowledge was analyzed using one way ANOVA. The impact on educator phonological awareness abilities, phonological awareness general knowledge, and beliefs was analyzed using a 3 X (2 X S) mixed analyses of variance to examine the pretest to posttest change between educators participating the three conditions. Results revealed significant findings for increased engagement in professional learning and gains in educators general knowledge. This study is a first step in understanding effective adult teaching practices that may or may not contribute to better educator outcomes and promoting more effective professional learning experiences for early childhood educators.

  10. Sibling influences on theory of mind development for children with ASD. (United States)

    O'Brien, Karen; Slaughter, Virginia; Peterson, Candida C


    Research indicates that having child siblings is positively associated with theory of mind (ToM) in typically developing children. As ToM is important to everyday social behaviours it is important to extend this research to examine whether there are similar sibling effects for children with autism spectrum disorders (ASD). Theory of mind and executive functioning abilities of 60 children clinically diagnosed with ASD were assessed with batteries of standard tasks. Verbal mental age (VMA) and severity of autism symptoms were also measured together with number of child-aged siblings (1 to 12 years) and position in the sibling constellation. Having older siblings was a significant negative predictor of ToM performance for children with ASD, even after controlling for age, VMA, executive function and autism symptom severity. A weaker ToM benefit of younger siblings was not statistically significant independently of control variables. In sharp contrast to findings for typically developing preschoolers, having an older sibling was a disadvantage for ToM development in children with ASD. Conceivably, older siblings may over-compensate for their younger ASD siblings in social interactions, thereby limiting opportunities for social-cognitive growth. Parental attitudes, family resources, cultural norms and access to educational interventions may also conceivably be relevant and clearly warrant further research. © 2011 The Authors.

  11. Historical Aspects of Development of Russian-Ukrainian Theory of Deep, Abiotic Origin of Petroleum (United States)

    Gabdrakhmanov, Rinat; Minibaev, Nail


    The origin of oil and gas arouses great interest because the success of their search depends on the correct perspective on this issue. Any theory arises on the basis of factual material and works up until new evidence does not begin to contradict her. Just such a situation has developed in the question of the oil and gas genesis nowadays. Collected morden results of geological and geophysical investigation of oil and gas fields and results of deep drilling and well monitoring did not link to traditional concepts about the genesis of hydrocarbons. The modern Russian-Ukrainian theory of deep, abiotic petroleum genesis developed from the sciences of chemistry and thermodynamics, geology, geochemistry, geophysics. This theory deals with many aspects of deep process in the mantle and earth crust. Development of any theory ore hypothesis has individual history of emergence, main directions of progress. The history of petroleum science had begun in the 1757 when the Russian person of natural gifts M. Lomonosov suggested the hypothesis that oil might originate from biological detritus. During the end of the nineteenth century famous Russian chemist Dmitriy Mendeleev stated clearly that oil is a primordial, native material from great depth, mantle. The modern Russian-Ukrainian theory of abiotic origin of oil and gas was first enunciated clearly by Nikolay Kudryavtsev at the International petroleum geological congress. Acquirement of development history of science theoretical base of Russian-Ukrainian theory of abiotic petroleum genesis is the most part of oil geology and geological science. Development of this science theoretical base deals with names of famous scientists and investigators as P. Kropotkin, V. Porfir'yev, N. Kudryavtsev, V. Kraiushkin V.Linetskii, K. Anikiev, and another. Investigation of historical aspect affords an opportunity to demonstrate connection between origin of petroleum and deep structure of the Earth, up-to-date tectonic process, thermodynamic

    Jina Chun


    Full Text Available Youth with disabilities face difficulties resulting from attitudinal, environmental, and organizational barriers not only in initially accessing and entering school (World Health Organization [WHO], 2011, but also as they transition from school age youth to working adults. With a focus on facilitating a better understanding of the issues, challenges, and solutions associated with the design and implementation of career development services for youth with disabilities, this article describes the status quo for students with disabilities in South Korea and then discusses career development services that potentially reduce variation, help facilitate optimal career development, and promote future employment opportunities. To accomplish this task, we explore the intersection of culture, theory, and policy in the Korean transition service delivery system.

  14. Development of an intervention to improve appropriate polypharmacy in older people in primary care using a theory-based method

    Directory of Open Access Journals (Sweden)

    Cathal A. Cadogan


    Full Text Available Abstract Background It is advocated that interventions to improve clinical practice should be developed using a systematic approach and intervention development methods should be reported. However, previous interventions aimed at ensuring that older people receive appropriate polypharmacy have lacked details on their development. This study formed part of a multiphase research project which aimed to develop an intervention to improve appropriate polypharmacy in older people in primary care. Methods The target behaviours for the intervention were prescribing and dispensing of appropriate polypharmacy to older patients by general practitioners (GPs and community pharmacists. Intervention development followed a systematic approach, including previous mapping of behaviour change techniques (BCTs to key domains from the Theoretical Domains Framework that were perceived by GPs and pharmacists to influence the target behaviours. Draft interventions were developed to operationalise selected BCTs through team discussion. Selection of an intervention for feasibility testing was guided by a subset of the APEASE (Affordability, Practicability, Effectiveness/cost-effectiveness, Acceptability, Side-effects/safety, Equity criteria. Results Three draft interventions comprising selected BCTs were developed, targeting patients, pharmacists and GPs, respectively. Following assessment of each intervention using a subset of the APEASE criteria (affordability, practicability, acceptability, the GP-targeted intervention was selected for feasibility testing. This intervention will involve a demonstration of the behaviour and will be delivered as an online video. The video demonstrating how GPs can prescribe appropriate polypharmacy during a typical consultation with an older patient will also demonstrate salience of consequences (feedback emphasising the positive outcomes of performing the behaviour. Action plans and prompts/cues will be used as complementary

  15. The current status of the psychoanalytic theory of instinctual drives. I: Drive concept, classification, and development. (United States)

    Compton, A


    The evolution of Freud's theory of instinctual drives, with the accompanying models of a mental apparatus, is remarkable for its tenacious adherence to addressing the fundamental problems of human psychology, here phrased as the problems of body-mind-environment relationships. The concept of instinctual drives continues to be one of the most pervasive concepts of psychoanalysis, weathering considerable attack over the last several decades, although losing some clarity in the process. I have cited and discussed as basic issues of the concept of instinctual drives: the relationship of observational data and theoretical constructs in psychology; whether our construct of drives is or should be or can be purely psychological; the problem of conceptualizing the ontogenetic origin of mind; the issues of the "force-meaning conjunction" and the problem of psychic energy in psychoanalytic constructs; and the relation of our concept of instinctual drives to the concept of instincts in general. It seems that progress with these fundamental issues might be made by utilizing models that are more homologous with present knowledge in related fields than is Freud's reflex arc model of the nervous system, in order to build a better drive construct within the framework of psychoanalysis. The classification of instinctual drives remains a problem. Clinically, aggression seems to be a factor in conflict, very much like sexuality. Despite widespread acceptance of the idea of aggression as simply parallel to sexuality in all respects, there are major discrepancies. Perhaps aggression cannot be viewed as a drive after all; perhaps our drive construct needs to be modified to accommodate aggression. Certainly, controversy in this area has interfered with the production of good clinical studies which could begin to increase our understanding of aggression and its place in the human personality. The psychoanalytic theory of drive development has probably undergone less change in the last

  16. Coase and international business: the origin and development of internalisation theory


    Casson, Mark


    The internalisation theory of the multinational enterprise is a significant intellectual legacy of Ronald Coase. US direct investment in Europe became highly political in the 1960s, and neoclassical trade theory had no explanation. A theory of the multi-plant enterprise was required, and internalisation theory filled this gap. Using Coasian economics to explain the ownership of production plants, and the geography of trade to explain their location, internalisation theory offered a comprehens...

    Rayla Amaral Lemos


    Full Text Available Abstract OBJECTIVE Understanding the conceptions of premature children caregivers on child development and associated factors. METHOD An exploratory-descriptive qualitative study of 12 families with children under three years of age. Interviews were submitted to thematic content analysis, systematized into the categories of Bioecological Theory of Human Development: Process, Person, Context and Time, and in the Functional Development category. RESULTS There are concerns about impairment in the current and future development of a Person/child defined as fragile as a result of premature birth (Time dimension, minimized by the scope of observable competencies such as motor skills. The Context, especially family and health services, and Proximal Processes, described as one-way caregiver interactions, are considered determinants of development. Functional Development is considered a natural consequence and result of education. The support network is crucial, supporting or limiting care. CONCLUSION Concerns about the development mobilize caregivers to stimulate the premature child/person and requests family and healthcare assistance.

  18. Congruency sequence effects are driven by previous-trial congruency, not previous-trial response conflict


    Weissman, Daniel H.; Carp, Joshua


    Congruency effects in distracter interference tasks are often smaller after incongruent trials than after congruent trials. However, the sources of such congruency sequence effects (CSEs) are controversial. The conflict monitoring model of cognitive control links CSEs to the detection and resolution of response conflict. In contrast, competing theories attribute CSEs to attentional or affective processes that vary with previous-trial congruency (incongruent vs. congruent). The present study s...

  19. Comparing the Effects of Two Facets of Multiple Intelligences Theory on Developing EFL Learners’ Listening

    Directory of Open Access Journals (Sweden)

    Ma’ssoumeh Bemani Naeini


    Full Text Available Gardner’s Multiple Intelligences Theory (MIT, however having been embraced in the field of language acquisition, has apparently failed to play a role in research on learning styles as an alternative construct.  This study aims at examining the potential effects of MI-based activities, as learning styls, on the listening proficiency of Iranian TEFL university students.  Based on two assumptions derived from MIT, one of the experimental groups (EG1; N=30 worked on activities across intelligences while the other experimental group (EG2; N=30 focused on the activities related to their most developed intelligence.  McKenzie’s (1999 MI Inventory was used to identify the subjects’ preferred intelligences. There was a significant difference between listening scores on TOEFL before and after the intervention of MI-based activities as well as between the two experimental groups, indicating EG1 outperforming EG2.  So, as the findings reveal, integration of MIT can significantly contribute to the enhancement of EFL learners’ listening comprehension and the effect is even more significant if teachers practice an integration of all intelligences rather than the most developed ones, only.    Keywords: Multiple Intelligences Theory, learning styles, listening proficiency, Iranian EFL context

  1. Development of a measure of work motivation for a meta-theory of motivation. (United States)

    Ryan, James C


    This study presents a measure of work motivation designed to assess the motivational concepts of the meta-theory of motivation. These concepts include intrinsic process motivation, goal internalization motivation, instrumental motivation, external self-concept motivation, and internal self-concept motivation. Following a process of statement development and identification, six statements for each concept were presented to a sample of working professionals (N = 330) via a paper-and-pencil questionnaire. Parallel analysis supported a 5-factor solution, with a varimax rotation identifying 5 factors accounting for 48.9% of total variance. All 5 scales had Cronbach alpha coefficients above .70. Limitations of the newly proposed questionnaire and suggestions for its further development and use are discussed.

Mozambique has developed training activities (72%), management support (38%) and direct health care (27%), focused on the area of the fight against infection and tropical diseases. In Angola, the activities are based in training (37%), management support (37%) and health care (75%) in the area of basic health services (25%), fighting against tropical diseases (50%) and improving maternal and child health (25%). Namibia focuses on the health care area (100%) through direct assistance activities and management support. Health cooperation programs developed by the Spanish state have probed to work as partial compensation system.

  4. An Evolutionary Route for the Moral Development of Nursing Students: A Constructivist Grounded Theory. (United States)

    Ranjbar, Hadi; Joolaee, Soodabeh; Vedadhir, Abouali; Abbasszadeh, Abbass; Bernstein, Colleen


    Developing moral competency is a main aim of educational systems, especially in healthcare-related disciplines. The aim of this study was to explore the moral development process in nursing students. This study used a constructivist grounded theory. Twenty-five semistructured, face-to-face interview with 22 participants were conducted to gather the data. The participants were nursing students and educators attending three nursing schools in Tehran. Moral development evolves within nursing students following a stepwise progression. Within each step or phase, students experience specific changes with regard to both their practical skills and their moral capabilities and competencies. Three main steps were identified: moral transition, moral reconstruction, and moral internalization. Techno-scientific competence, biomedical competence, and nursing competence are developed in each step, respectively. Moral competency in nursing students develops along with their competency as nursing practitioners. To facilitate progress through each phase, it needs to be ensured that the learning experiences that students are exposed to during each consecutive year of study facilitate as much as possible the development of moral competence.

  5. Development of a Food Safety and Nutrition Education Program for Adolescents by Applying Social Cognitive Theory. (United States)

    Lee, Jounghee; Jeong, Soyeon; Ko, Gyeongah; Park, Hyunshin; Ko, Youngsook


    The purpose of this study was to develop an educational model regarding food safety and nutrition. In particular, we aimed to develop educational materials, such as middle- and high-school textbooks, a teacher's guidebook, and school posters, by applying social cognitive theory. To develop a food safety and nutrition education program, we took into account diverse factors influencing an individual's behavior, such as personal, behavioral, and environmental factors, based on social cognitive theory. We also conducted a pilot study of the educational materials targeting middle-school students (n = 26), high-school students (n = 24), and dietitians (n = 13) regarding comprehension level, content, design, and quality by employing the 5-point Likert scale in May 2016. The food safety and nutrition education program covered six themes: (1) caffeine; (2) food additives; (3) foodborne illness; (4) nutrition and meal planning; (5) obesity and eating disorders; and (6) nutrition labeling. Each class activity was created to improve self-efficacy by setting one's own goal and to increase self-control by monitoring one's dietary intake. We also considered environmental factors by creating school posters and leaflets to educate teachers and parents. The overall evaluation score for the textbook was 4.0 points among middle- and high-school students, and 4.5 points among dietitians. This study provides a useful program model that could serve as a guide to develop educational materials for nutrition-related subjects in the curriculum. This program model was created to increase awareness of nutrition problems and self-efficacy. This program also helped to improve nutrition management skills and to promote a healthy eating environment in middle- and high-school students.

  6. Understanding minds: early cochlear implantation and the development of theory of mind in children with profound hearing impairment. (United States)

    Sundqvist, Annette; Lyxell, Björn; Jönsson, Radoslava; Heimann, Mikael


    The present study investigates how auditory stimulation from cochlear implants (CI) is associated with the development of Theory of Mind (ToM) in severely and profoundly hearing impaired children with hearing parents. Previous research has shown that deaf children of hearing parents have a delayed ToM development. This is, however, not always the case with deaf children of deaf parents, who presumably are immersed in a more vivid signing environment. Sixteen children with CI (4.25 to 9.5 years of age) were tested on measures of cognitive and emotional ToM, language and cognition. Eight of the children received their first implant relatively early (before 27 months) and half of them late (after 27 months). The two groups did not differ in age, gender, language or cognition at entry of the study. ToM tests included the unexpected location task and a newly developed Swedish social-emotional ToM test. The tests aimed to test both cognitive and emotional ToM. A comparison group of typically developing hearing age matched children was also added (n=18). Compared to the comparison group, the early CI-group did not differ in emotional ToM. The late CI-group differed significantly from the comparison group on both the cognitive and emotional ToM tests. The results revealed that children with early cochlear implants solved ToM problems to a significantly higher degree than children with late implants, although the groups did not differ on language or cognitive measures at baseline. The outcome suggests that early cochlear implantation for deaf children in hearing families, in conjunction with early social and communicative stimulation in a language that is native to the parents, can provide a foundation for a more normalized ToM development.

  7. Development of a behaviour change intervention: a case study on the practical application of theory. (United States)

    Porcheret, Mark; Main, Chris; Croft, Peter; McKinley, Robert; Hassell, Andrew; Dziedzic, Krysia


    Use of theory in implementation of complex interventions is widely recommended. A complex trial intervention, to enhance self-management support for people with osteoarthritis (OA) in primary care, needed to be implemented in the Managing Osteoarthritis in Consultations (MOSAICS) trial. One component of the trial intervention was delivery by general practitioners (GPs) of an enhanced consultation for patients with OA. The aim of our case study is to describe the systematic selection and use of theory to develop a behaviour change intervention to implement GP delivery of the enhanced consultation. The development of the behaviour change intervention was guided by four theoretical models/frameworks: i) an implementation of change model to guide overall approach, ii) the Theoretical Domains Framework (TDF) to identify relevant determinants of change, iii) a model for the selection of behaviour change techniques to address identified determinants of behaviour change, and iv) the principles of adult learning. Methods and measures to evaluate impact of the behaviour change intervention were identified. The behaviour change intervention presented the GPs with a well-defined proposal for change; addressed seven of the TDF domains (e.g., knowledge, skills, motivation and goals); incorporated ten behaviour change techniques (e.g., information provision, skills rehearsal, persuasive communication); and was delivered in workshops that valued the expertise and professional values of GPs. The workshops used a mixture of interactive and didactic sessions, were facilitated by opinion leaders, and utilised 'context-bound communication skills training.' Methods and measures selected to evaluate the behaviour change intervention included: appraisal of satisfaction with workshops, GP report of intention to practise and an assessment of video-recorded consultations of GPs with patients with OA. A stepped approach to the development of a behaviour change intervention, with the

  8. How online sexual health services could work; generating theory to support development. (United States)

    Baraitser, Paula; Syred, Jonathan; Spencer-Hughes, Vicki; Howroyd, Chris; Free, Caroline; Holdsworth, Gillian


    Online sexual health services are an emerging area of service delivery. Theory of change critically analyses programmes by specifying planned inputs and articulating the causal pathways that link these to anticipated outcomes. It acknowledges the changing and contested nature of these relationships. We developed two versions of a theory of change for an online sexual health service. The first articulated the theory presented in the original programme proposal and the second documented its development in the early stages of implementation through interviews with key programme stakeholders. The programme proposal described an autonomous and empowered user completing a sexual health check using a more convenient, accessible and discreet online service and a shift from clinic based to online care. The stakeholder interviews confirmed this and described new and more complex patterns of service use as the online service creates opportunities for providers to contact users outside of the traditional clinic visit and users move between online and clinic based care. They described new types of user/provider relationships which we categorised as: those influenced by an online retail culture; those influenced by health promotion outreach and surveillance and those acknowledging the need for supported access. This analysis of stakeholder views on the likely the impacts of online sexual health services suggests three areas for further thinking and research. 1.

  9. Iterative development of Vegethon: a theory-based mobile app intervention to increase vegetable consumption. (United States)

    Mummah, Sarah A; King, Abby C; Gardner, Christopher D; Sutton, Stephen


    Mobile technology may serve as a cost-effective and scalable tool for delivering behavioral nutrition interventions. This research sought to iteratively develop a theory-driven mobile app, Vegethon, to increase vegetable consumption. Development of Vegethon followed phases outlined by the IDEAS framework: 1) empathize with users (qualitative interviews, n = 18); 2) specify target behavior; 3) ground in behavioral theory; 4) ideate implementation strategies; 5) prototype potential products; 6) gather user feedback (qualitative interviews, n = 14; questionnaire, n = 41); 7) build minimum viable product; and 8) pilot potential efficacy and usability (pilot RCT, n = 17). Findings from each phase informed subsequent phases. The target population that informed intervention development was 18-50 years of age, had BMIs of 28-40 kg/m(2), and lived in the geographical area surrounding Stanford University. A full description of the final version of Vegethon is included in the paper. Qualitative findings that shaped initial intervention conception were: participants' interests in accountability without judgment; their desire for simple and efficient dietary self-monitoring; and the importance of planning meals in advance. Qualitative findings identified during intervention refinement were the need for a focus on vegetable self-monitoring; inclusion of vegetable challenges; simplification of features; advice and inspiration for eating vegetables; reminder notifications; and peer comparison. Pilot RCT findings suggested the initial efficacy, acceptance, and feasibility of the intervention. The final version of Vegethon enabled easy self-monitoring of vegetable consumption and included a range of features designed to engage the user (e.g., surprise challenges; leaderboard; weekly reports). Vegethon was coded for its inclusion of 18 behavior change techniques (BCTs) (e.g., goal setting; feedback; social comparison; prompts/cues; framing/reframing; identity

  10. Development of a behaviour change intervention: a case study on the practical application of theory (United States)


    Background Use of theory in implementation of complex interventions is widely recommended. A complex trial intervention, to enhance self-management support for people with osteoarthritis (OA) in primary care, needed to be implemented in the Managing Osteoarthritis in Consultations (MOSAICS) trial. One component of the trial intervention was delivery by general practitioners (GPs) of an enhanced consultation for patients with OA. The aim of our case study is to describe the systematic selection and use of theory to develop a behaviour change intervention to implement GP delivery of the enhanced consultation. Methods The development of the behaviour change intervention was guided by four theoretical models/frameworks: i) an implementation of change model to guide overall approach, ii) the Theoretical Domains Framework (TDF) to identify relevant determinants of change, iii) a model for the selection of behaviour change techniques to address identified determinants of behaviour change, and iv) the principles of adult learning. Methods and measures to evaluate impact of the behaviour change intervention were identified. Results The behaviour change intervention presented the GPs with a well-defined proposal for change; addressed seven of the TDF domains (e.g., knowledge, skills, motivation and goals); incorporated ten behaviour change techniques (e.g., information provision, skills rehearsal, persuasive communication); and was delivered in workshops that valued the expertise and professional values of GPs. The workshops used a mixture of interactive and didactic sessions, were facilitated by opinion leaders, and utilised ‘context-bound communication skills training.’ Methods and measures selected to evaluate the behaviour change intervention included: appraisal of satisfaction with workshops, GP report of intention to practise and an assessment of video-recorded consultations of GPs with patients with OA. Conclusions A stepped approach to the development of a

  11. Workplace bullying in emergency nursing: Development of a grounded theory using situational analysis. (United States)

    Wolf, Lisa A; Perhats, Cydne; Clark, Paul R; Moon, Michael D; Zavotsky, Kathleen Evanovich


    The Institute of Medicine recognizes that the workplace environment is a crucial factor in the ability of nurses to provide safe and effective care, and thus interactions that affect the quality and safety of the work environment require exploration. The purpose of this study was to use situational analysis to develop a grounded theory of workplace bullying as it manifests specifically in the emergency care setting. This study used a grounded theory methodology called situational analysis. 44 emergency RNs were recruited to participate in one of 4 focus group sessions, which were transcribed in their entirety, and, along with field notes, served as the dataset. This grounded theory describes the characteristics of human actors and their reactions to conditions in the practice environment that lead to greater or lesser levels of bullying, and the responses to bullying as it occurs in U.S. emergency departments. Workplace bullying is a significant factor in the dynamics of patient care, nursing work culture, and nursing retention. The impact on patient care cannot be overestimated, both in terms of errors, substandard care, and the negative effects of high turnover of experienced RNs who leave, compounded by the inexperience of newly hired RNs. An assessment of hospital work environments should include nurse perceptions of workplace bullying, and interventions should focus on effective managerial processes for handling workplace bullying. Future research should include testing of the theoretical coherence of the model, and the testing of bullying interventions to determine the effect on workplace environment, nursing intent to leave/retention, and patient outcomes.

    Schapira, Marilyn M; Walker, Cindy M; Cappaert, Kevin J; Ganschow, Pamela S; Fletcher, Kathlyn E; McGinley, Emily L; Del Pozo, Sam; Schauer, Carrie; Tarima, Sergey; Jacobs, Elizabeth A


    Health numeracy can be defined as the ability to understand and apply information conveyed with numbers, tables and graphs, probabilities, and statistics to effectively communicate with health care providers, take care of one's health, and participate in medical decisions. To develop the Numeracy Understanding in Medicine Instrument (NUMi) using item response theory scaling methods. A 20-item test was formed drawing from an item bank of numeracy questions. Items were calibrated using responses from 1000 participants and a 2-parameter item response theory model. Construct validity was assessed by comparing scores on the NUMi to established measures of print and numeric health literacy, mathematic achievement, and cognitive aptitude. Community and clinical populations in the Milwaukee and Chicago metropolitan areas. Twenty-nine percent of the 1000 respondents were Hispanic, 24% were non-Hispanic white, and 42% were non-Hispanic black. Forty-one percent had no more than a high school education. The mean score on the NUMi was 13.2 (s = 4.6) with a Cronbach α of 0.86. Difficulty and discrimination item response theory parameters of the 20 items ranged from -1.70 to 1.45 and 0.39 to 1.98, respectively. Performance on the NUMi was strongly correlated with the Wide Range Achievement Test-Arithmetic (0.73, P < 0.001), the Lipkus Expanded Numeracy Scale (0.69, P < 0.001), the Medical Data Interpretation Test (0.75, P < 0.001), and the Wonderlic Cognitive Ability Test (0.82, P < 0.001). Performance was moderately correlated to the Short Test of Functional Health Literacy (0.43, P < 0.001). The NUMi was found to be most discriminating among respondents with a lower-than-average level of health numeracy. The NUMi can be applied in research and clinical settings as a robust measure of the health numeracy construct.

From our previous work, it is likely that the theories will include: theory of planned behaviour, social cognitive theory and the evidence-based strategy, implementation intention. The questionnaire data will measure predictor variables (theoretical constructs and outcome variables (intention and clinical decision, and will be analysed using multiple regression analysis. We aim to achieve 150 respondents in each of the four groups for each postal survey.

  14. Urban ecology in a developing world: why advanced socioecological theory needs Africa. (United States)

    McHale, Melissa R; Bunn, David N; Pickett, Steward Ta; Twine, Wayne


    Socioecological theory, developed through the study of urban environments, has recently led to a proliferation of research focusing on comparative analyses of cities. This research emphasis has been concentrated in the more developed countries of the Northern Hemisphere (often referred to as the "Global North"), yet urbanization is now occurring mostly in the developing world, with the fastest rates of growth in sub-Saharan Africa. Countries like South Africa are experiencing a variety of land-cover changes that may challenge current assumptions about the differences between urban and rural environments and about the connectivity of these dynamic socioecological systems. Furthermore, questions concerning ecosystem services, landscape preferences, and conservation - when analyzed through rural livelihood frameworks - may provide insights into the social and ecological resilience of human settlements. Increasing research on urban development processes occurring in Africa, and on patterns of kinship and migration in the less developed countries of the "Global South", will advance a more comprehensive worldview of how future urbanization will influence the progress of sustainable societies.

    Full Text Available Authors are in long term developing e-learning supports for some parts of Operation Research course. The original purpose was to prepare e-learning supports for students of FBE Mendelu, mainly for part-time form students, who have subscribed Economic mathematical methods course (EMM. Considering decreasing number of lessons on part-time form of study (16 hours in a semester, in comparison to 56 hours in full-time form of study, was for part-time form students even more difficult to fulfill exam requirements. As a help for students there was stage by stage prepared several of programs, they allow self-contained practicing of some linear programming methods. Programs did allow to users step-by-step verify their solution, i.e. whether their calculation are in accordance with algorithm described in lectures. Advantage for the students consists in fact, that each mistake (numerical or algorithmic they were able to uncover, what contributes to increase of self-study effectiveness and from that resulting higher study motivation. Resulting from existing experience, authors decided to request for a new FRVŠ grant for academic year 2012, focused on e-learning support of selected graph theory problems. Within this project there was developed a tool allowing to make and according to the user needs interactively modify created graphs. On this graph it is possible individually, step by step (in compliance with on lectures presented algorithm to practice solving of selected graph theory and network analysis problems (e.g. minimal spanning tree, shortest path in a graph, testing for cycles in a graph, critical path method etc.. Project is realized as modular and was realized in Delphi developing tool. Described algorithms are saved in dynamic linked libraries. There for it is very easy to add here new (newly programmed algorithms.

    Ashworth Mark


    Full Text Available Abstract Background Non-adherence to clinical guidelines has been identified as a consistent finding in general practice. The purpose of this study was to develop theory-informed, computer-delivered interventions to promote the implementation of guidelines in general practice. Specifically, our aim was to develop computer-delivered prompts to promote guideline adherence for antibiotic prescribing in respiratory tract infections (RTIs, and adherence to recommendations for secondary stroke prevention. Methods A qualitative design was used involving 33 face-to-face interviews with general practitioners (GPs. The prompts used in the interventions were initially developed using aspects of social cognitive theory, drawing on nationally recommended standards for clinical content. The prompts were then presented to GPs during interviews, and iteratively modified and refined based on interview feedback. Inductive thematic analysis was employed to identify responses to the prompts and factors involved in the decision to use them. Results GPs reported being more likely to use the prompts if they were perceived as offering support and choice, but less likely to use them if they were perceived as being a method of enforcement. Attitudes towards using the prompts were also related to anticipated patient outcomes, individual prescriber differences, accessibility and presentation of prompts and acceptability of guidelines. Comments on the prompts were largely positive after modifying them based on participant feedback. Conclusions Acceptability and satisfaction with computer-delivered prompts to follow guidelines may be increased by working with practitioners to ensure that the prompts will be perceived as valuable tools that can support GPs' practice.

  17. Examination of the teaching styles of nursing professional development specialists, part I: best practices in adult learning theory, curriculum development, and knowledge transfer. (United States)

    Curran, Mary K


    The American Nurses Association advocates for nursing professional development (NPD) specialists to have an earned graduate degree, as well as educational and clinical expertise. However, many NPD specialists have limited exposure to adult learning theory. Limited exposure to adult learning theory may affect NPD educational practices, learning outcomes, organizational knowledge transfer, and subsequently, the professional development of the nurses they serve and quality of nursing care. An examination of current teaching practices may reveal opportunities for NPD specialists to enhance educational methods to promote learning, learning transfer, and organizational knowledge and excellence. This article, the first in a two-part series, examines best practices of adult learning theories, nursing professional development, curriculum design, and knowledge transfer. Part II details the results of a correlational study that examined the effects of four variables on the use of adult learning theory to guide curriculum development for NPD specialists in hospitals.

  18. Normalisation process theory: a framework for developing, evaluating and implementing complex interventions

    LENUS (Irish Health Repository)

    Murray, Elizabeth


    Abstract Background The past decade has seen considerable interest in the development and evaluation of complex interventions to improve health. Such interventions can only have a significant impact on health and health care if they are shown to be effective when tested, are capable of being widely implemented and can be normalised into routine practice. To date, there is still a problematic gap between research and implementation. The Normalisation Process Theory (NPT) addresses the factors needed for successful implementation and integration of interventions into routine work (normalisation). Discussion In this paper, we suggest that the NPT can act as a sensitising tool, enabling researchers to think through issues of implementation while designing a complex intervention and its evaluation. The need to ensure trial procedures that are feasible and compatible with clinical practice is not limited to trials of complex interventions, and NPT may improve trial design by highlighting potential problems with recruitment or data collection, as well as ensuring the intervention has good implementation potential. Summary The NPT is a new theory which offers trialists a consistent framework that can be used to describe, assess and enhance implementation potential. We encourage trialists to consider using it in their next trial.

    Full Text Available Empathy and theory of mind (ToM are distinctive psychological constructs in predicting children’s social functioning. This study provided evidence of the independent nature of these constructs and developed a parent questionnaire for measuring individual differences in children’s empathy and ToM. In Study 1, exploratory factor analysis and confirmatory factor analysis based on responses of 116 parents of Hong Kong children established a three-factor structure of the Empathy and Theory of Mind Scale (EToMS, that is, Empathy, Nice ToM, and Nasty ToM. An additional 189 parents of Study 2 confirmed this three-factor model. A subsample of 93 children (M=4.97, SD = .84, 47 boys from Study 2 took part in child measures of helping and lying behaviors as well as false belief understanding. The results supported the reliability and validity of the EToMS, making it a useful assessment of children’s social predispositions.

  1. On several problems regarding the development of demographic theory in China since the founding of the People's Republic. (United States)

    Feng, S


    Policy theory over the last 30 years, as Comrade Tian sees it, can be divided into 3 developmental stages: 1) from 1949 to 1957 saw the rise of "population controlism" represented by the sociological school; 2) from the late 1950s into the early 1960s featured the "new Population Theory" represented by Ma Yinchu, and a "theory of human hands and power" formulated in the course of criticism and repudiation; and 3) after the 1960s population studies were at a state of standstill or only 1/2 active. While advocating birth control, Comrade Mao Zedong showed inadequacy in regard to demographic theory and in practice he lacked sufficient understanding of the gravity of New China's population problem. In reviewing the developmental history of demographic theory in new China, it would be very inappropriate not to analyze and evaluate realistically Mao Zedong's thinking on population but only criticize certain of his faults. The main manifestations in Comrade Tian Xueyuan's division of the stages of development of new China's population theory are: 1) the first stage is unable to reflect accurately the objective reality of a healthy development of China's population theory, 2) the third stage includes 2 entirely different developmental periods before and after the smashing of the "gang of four," and 3) Tian's stages did not convey the development and change in Comrade Mao Zedong's demographic thinking in the different stages and their influence on the development of China's population theory. Tian Xueyuan and Zedong differ in terms of content of the developmental stages of population theory, not in terms of the time of the stages.

The theory of noosphere has become the philosophical basis of the concept for sustainable development of society, a strategy for balanced economic development and natural resource management, and continues to have great influence on modern environmental awareness and as often happens with great scientists, that walk ahead of their time, Vernadsky’s scientific legacy will still be comprehended and creatively developed by the next generations. Vernadsky suggested the change of attitudes and ideological principles, i.e. noospheric thinking, as the solution for environmental problems. Therefore, today, Vernadsky's teachings of biosphere-noosphere transition is of particular relevance that could be the basis for fundamental research of environmental issues and practical search for their resolution. According to Vernadsky, the basic prerequisites for the development of the noosphere are the following: humanity should be united; means of communication and exchange should be transformed; the discovery of new energy sources; the rise of well-being, equality of all people; conflict-free society.Conclusion. The knowledge of the development of the biosphere is the key to rational nature management. Vernadsky concludes that humanity, in the course of its development, is transformed into a powerful new geological force, and with thought and action it changes the face of the planet. Accordingly, for the purpose of its preservation, the humanity will have to take responsibility for the development of the biosphere turning into noosphere, and it will require a certain social organization and new environmental and humanistic ethics at the same time.

    Schomerus, Volker


    Since its conception in the 1960s, string theory has been hailed as one of the most promising routes we have to unify quantum mechanics and general relativity. This book provides a concise introduction to string theory explaining central concepts, mathematical tools and covering recent developments in physics including compactifications and gauge/string dualities. With string theory being a multidisciplinary field interfacing with high energy physics, mathematics and quantum field theory, this book is ideal for both students with no previous knowledge of the field and scholars from other disciplines who are looking for an introduction to basic concepts.

  8. The role of migration in the regional development and its appearance in the theories

    Directory of Open Access Journals (Sweden)

    Tünde Patay


    Full Text Available Phenomena relating to migration have a number of social, economic and political effects on both the sending and the host country. These impacts can vary depending on the reference period, region or sector as well as on the goals and aspects of our interpretation. Analysing the interference between immigration and regional development, we can rely on classic migration theories, however, a comparison of further models and concepts relating development and regional issues can be more useful for researchers. Another important question in connection with regional competitiveness is how decision makers act and react after perceiving migratory movements, thus this paper also aims to summarize the mainstream solutions and the controversies of migration policies that appear in the literature. Therefore it analyses the importance of integration and the main factors of inclusion as well. Besides, the aspects of methods and methodology also need appropriate attention. The paper finally presents these methodological issues of migration research exploring the typical questions and stumbling stones. These questions are relevant, since regional development and the strategies in the background have strong association with migratory phenomena. However, a well-structured perspective is needed to confront the theoretical background of the 4 main areas: regional development, regional policy, migration and issues from research methods.

  9. From conflict to collaboration? Contrasts and convergence in the development of nursing and management theory. (United States)

    Hewison, Alistair; Stanton, Angela


    This is the first of two papers which examine the development of theory in the occupations of management and nursing, in order to determine where the similarities and differences lie. The need for the Health Service to be effectively managed was a prominent feature of UK health policy in the 1980s and early 1990s and accounts of the introduction of 'management methods' into health care tend to focus on the conflict between management and nursing. More recently, however, the policy emphasis has shifted towards collaborative and co-operative approaches to the provision of health care. An examination of the development of nursing is conducted as the first step in identifying areas of contrast and convergence in the development of nursing and managerial ideologies. In the second paper a similar approach is taken to the history of management. Nursing has been subject to a succession of ideologies aimed at advancing practice, however, many of these approaches have been accepted in an uncritical way. In the second paper the similarities in the development of management thought are examined and the implications this has for nursing management explored.

    The aim was to gather empirical data on the social construction of the technical core of scientific culture and to contribute to sociological theory through an analysis of these data. The development of high energy physics between 1974 and 1977, specifically the production of experimental and theoretical knowledge on a family of 'new particles', was studied. By the end of this period theoretical consensus on the nature of these particles had been achieved. Methods of investigation included a literature survey and the collection of archival material and of opinions and recollections of important personalities involved. The work of R.K. Merton and his followers was used as a basis for investigating the sociology of scientific communities; also the work of T.S. Kuhn. A brief summary of the sociological analysis of the empirical data is given. (author)

  12. Bridging Theory and Practice: Developing Guidelines to Facilitate the Design of Computer-based Learning Environments

    Directory of Open Access Journals (Sweden)

    Lisa D. Young


    Full Text Available Abstract. The design of computer-based learning environments has undergone a paradigm shift; moving students away from instruction that was considered to promote technical rationality grounded in objectivism, to the application of computers to create cognitive tools utilized in constructivist environments. The goal of the resulting computer-based learning environment design principles is to have students learn with technology, rather than from technology. This paper reviews the general constructivist theory that has guided the development of these environments, and offers suggestions for the adaptation of modest, generic guidelines, not mandated principles, that can be flexibly applied and allow for the expression of true constructivist ideals in online learning environments.

  13. Systems genomics analysis centered on epigenetic inheritance supports development of a unified theory of biology. (United States)

    Sharma, Abhay


    New discoveries are increasingly demanding integration of epigenetics, molecular biology, genomic networks and physiology with evolution. This article provides a proof of concept for evolutionary transgenerational systems biology, proposed recently in the context of epigenetic inheritance in mammals. Gene set enrichment analysis of available genome-level mammalian data presented here seem consistent with the concept that: (1) heritable information about environmental effects in somatic cells is communicated to the germline by circulating microRNAs (miRNAs) or other RNAs released in physiological fluids; (2) epigenetic factors including miRNA-like small RNAs, DNA methylation and histone modifications are propagated across generations via gene networks; and (3) inherited epigenetic variations in the form of methylated cytosines are fixed in the population as thymines over the evolutionary time course. The analysis supports integration of physiology and epigenetics with inheritance and evolution. This may catalyze efforts to develop a unified theory of biology. © 2015.

    The Theory of Planned Behavior (TPB) is one of the main theoretical models in the study of the different variables, which influence in the practise of physical activity. The aim in this study was to develop a questionnaire based on TPB in physical activity context providing evidence for the validity of the obtained measures. The instrumental project included three independent studies. The first study entailed the construction and qualitative assessment of the items. In the second study, the analysis of factorial structure was performed by means of exploratory measures, and it showed that the reliability of measures was adequate. The third study provided evidence on the dimensionality of the scale. The confirmatory factorial analysis guaranteed the stability of factorial structure proposed by the TPB and provided evidence for the internal validity of the inventory. Moreover, this study provided evidence of its external validity.

  15. Application and development of the Schwinger multichannel scattering theory and the partial differential equation theory of electron-molecule scattering (United States)

    Weatherford, Charles A.


    One version of the multichannel theory for electron-target scattering based on the Schwinger variational principle, the SMC method, requires the introduction of a projection parameter. The role of the projection parameter a is investigated and it is shown that the principal-value operator in the SMC equation is Hermitian regardless of the value of a as long as it is real and nonzero. In a basis that is properly orthonormalizable, the matrix representation of this operator is also Hermitian. The use of such basis is consistent with the Schwinger variational principle because the Lippmann-Schwinger equation automatically builds in the correct boundary conditions. Otherwise, an auxiliary condition needs to be introduced, and Takatsuka and McKoy's original value of a is one of the three possible ways to achieve Hermiticity. In all cases but one, a can be uncoupled from the Hermiticity condition and becomes a free parameter. An equation for a based on the variational stability of the scattering amplitude is derived; its solution has an interesting property that the scattering amplitude from a converged SMC calculation is independent of the choice of a even though the SMC operator itself is a-dependent. This property provides a sensitive test of the convergence of the calculation. For a static-exchange calculation, the convergence requirement only depends on the completeness of the one-electron basis, but for a general multichannel case, the a-invariance in the scattering amplitude requires both the one-electron basis and the N plus 1-electron basis to be complete. The role of a in the SMC equation and the convergence property are illustrated using two examples: e-CO elastic scattering in the static-exchange approximation, and a two-state treatment of the e-H2 Chi(sup 1)Sigma(sub g)(+) yields b(sup 3)Sigma(sub u)(+) excitation.

  16. Toward a General Theory for Multiphase Turbulence Part I: Development and Gauging of the Model Equations

    Energy Technology Data Exchange (ETDEWEB)

    B. A. Kashiwa; W. B. VanderHeyden


    A formalism for developing multiphase turbulence models is introduced by analogy to the phenomenological method used for single-phase turbulence. A sample model developed using the formalism is given in detail. The procedure begins with ensemble averaging of the exact conservation equations, with closure accomplished by using a combination of analytical and experimental results from the literature. The resulting model is applicable to a wide range of common multiphase flows including gas-solid, liquid-solid and gas-liquid (bubbly) flows. The model is positioned for ready extension to three-phase turbulence, or for use in two-phase turbulence in which one phase is accounted for in multiple size classes, representing polydispersivity. The formalism is expected to suggest directions toward a more fundamentally based theory, similar to the way that early work in single-phase turbulence has led to the spectral theory. The approach is unique in that a portion of the total energy decay rate is ascribed to each phase, as is dictated by the exact averaged equations, and results in a transport equation for energy decay rate associated with each phase. What follows is a straightforward definition of a turbulent viscosity for each phase, and accounts for the effect of exchange of fluctuational energy among phases on the turbulent shear viscosity. The model also accounts for the effect of slip momentum transfer among the phases on the production of turbulence kinetic energy and on the tensor character of the Reynolds stress. Collisional effects, when appropriate, are included by superposition. The model reduces to a standard form in limit of a single, pure material, and is expected to do a credible job of describing multiphase turbulent flows in a wide variety of regimes using a single set of coefficients.

    Omer, Selma; Choi, Sunhea; Brien, Sarah; Parry, Marcus


    For an increasingly busy and geographically dispersed faculty, the Faculty of Medicine at the University of Southampton, United Kingdom, developed a range of Web-based faculty development modules, based on Kolb's experiential learning cycle, to complement the faculty's face-to-face workshops. The objective of this study was to assess users' views and perceptions of the effectiveness of Web-based faculty development modules based on Kolb's experiential learning cycle. We explored (1) users' satisfaction with the modules, (2) whether Kolb's design framework supported users' learning, and (3) whether the design principle impacts their work as educators. We gathered data from users over a 3-year period using evaluation surveys built into each of the seven modules. Quantitative data were analyzed using descriptive statistics, and responses to open-ended questions were analyzed using content analysis. Out of the 409 module users, 283 completed the survey (69.1% response rate). Over 80% of the users reported being satisfied or very satisfied with seven individual aspects of the modules. The findings suggest a strong synergy between the design features that users rated most highly and the key stages of Kolb's learning cycle. The use of simulations and videos to give the users an initial experience as well as the opportunity to "Have a go" and receive feedback in a safe environment were both considered particularly useful. In addition to providing an opportunity for reflection, many participants considered that the modules would enhance their roles as educators through: increasing their knowledge on various education topics and the required standards for medical training, and improving their skills in teaching and assessing students through practice and feedback and ultimately increasing their confidence. Kolb's theory-based design principle used for Web-based faculty development can support faculty to improve their skills and has impact on their role as educators

  18. How nursing home residents develop relationships with peers and staff: a grounded theory study. (United States)

    Roberts, Tonya; Bowers, Barbara


    Social support and social relationships have been repeatedly identified as essential to nursing home resident quality of life. However, little is known about ways residents develop relationships with peers or staff. This study was conducted to explore the ways resident develop relationships with peers and staff in nursing homes. Fifteen cognitively intact nursing home residents from two facilities were interviewed for this grounded theory study. Sampling, interviewing, and analysis occurred in a cyclical process with results at each stage of the study informing decisions about data collection and analysis in the next. Unstructured interviews and field observations were conducted. Data were analyzed with open, axial, and selective coding. Residents developed relationships with peers and staff largely as an unintended consequence of trying to have a life in the nursing home. Having a life was a two-step process. First, life motivations (Being Self and Creating a Positive Atmosphere) influenced resident preferences for daily activities and interaction goals and subsequently their strategies for achieving and establishing both. Second, the strategies residents used for achieving their required daily activities (Passing Time and Getting Needs Met) and interaction goals then influenced the nature of interaction and the subsequent peer or staff response to these interactions. Residents defined relationships as friendly or unfriendly depending on whether peers or staff responded positively or negatively. There was considerable overlap in the ways peer and staff relationships developed and the results highlight the role of peer and staff responsiveness in relationship development. The results provide possible explanations for the success of interventions in the literature designed to improve staff responsiveness to residents. The results suggest that adapting these kinds of interventions for use with peers may also be successful. The conceptual model also presents a number

  20. Theory of Mind Predicts Emotion Knowledge Development in Head Start Children. (United States)

    Seidenfeld, Adina M; Johnson, Stacy R; Cavadel, Elizabeth Woodburn; Izard, Carroll E


    Emotion knowledge (EK) enables children to identify emotions in themselves and others and its development facilitates emotion recognition in complex social situations. Social-cognitive processes, such as theory of mind (ToM), may contribute to developing EK by helping children realize the inherent variability associated with emotion expression across individuals and situations. The present study explored how ToM, particularly false belief understanding, in preschool predicts children's developing EK in kindergarten. Participants were 60 3- to 5-year-old Head Start children. ToM and EK measures were obtained from standardized child tasks. ToM scores were positively related to performance on an EK task in kindergarten after controlling for preschool levels of EK and verbal ability. Exploratory analyses provided preliminary evidence that ToM serves as an indirect effect between verbal ability and EK. Early intervention programs may benefit from including lessons on ToM to help promote socio-emotional learning, specifically EK. This consideration may be the most fruitful when the targeted population is at-risk.

  1. Age and gender dependent development of theory of mind in 6 to 8-years old children.

    Directory of Open Access Journals (Sweden)

    Cecilia Ines Calero


    Full Text Available The ability to attribute different mental states to distinct individuals, or Theory of Mind (ToM, is widely believed to be developed mostly during preschool years. How different factors such as gender, number of siblings or coarse personality traits affect this development is not entirely agreed upon. Here, we introduce a computerized version of the scaled ToM suite of tasks introduced by Wellman and Liu (2004, which allows us to meaningfully test ToM development on children 6 to 8-years old. We find that kids this age are still not entirely proficient in all ToM tasks, and continue to show a progression of performance with age. By testing this age range, too, we are able to observe a significant advantage of girls over boys in ToM performance. Other factors such as number of siblings, birth order, and coarse personality traits show no significant relation with the ToM task results. Finally, we introduce a novel way to quantify the scaling property of the suite involving a sequence of set inclusions and also, a comparison between specially tailored sets of logistic models. These measures confirm the validity of the scale in the 6 to 8-years old range.

  2. Collaborative Mother-Toddler Communication and Theory of Mind Development at Age 4 (United States)

    Sung, Jihyun; Hsu, Hui-Chin


    Focusing on social pragmatics, this longitudinal study investigated the contribution of mother-toddler collaborative communication to theory of mind (ToM) development at age 4. At age 2½, 78 toddlers’ (42 boys) and their mothers were observed during pretend play. At age 4, children were tested using 4 false belief understanding tasks. Both mothers and toddlers engaged in more collaborative (inform, guide/request, and support/confirm) than non-collaborative communication acts. Other-focused collaborative acts of support/confirm by mothers and toddlers predicted children’s false belief understanding, even after controlling for 5 covariates. In addition, as active agents in their own ToM development, the contribution of toddlers’ collaborative acts to false belief understanding was independent of their mothers. Finally, the way toddlers and their mothers co-constructing their communication mattered. Only when toddlers engaged in high levels of collaborative acts, the mothers’ high levels of collaborative acts demonstrated a positive effect on children’s ToM development. The applied implications of these findings were discussed. PMID:25132699

    Directory of Open Access Journals (Sweden)

    A. G. Mokronosov


    Full Text Available The paper considers the complex of economic processes in the sphere of the higher vocational education. The research is aimed at investigating, clarifying and systemizing the theoretical concepts of entrepreneur- ship in the context of the knowledge economy and rising competitiveness in the market of scientific and educational services. The research methodology basis involves the works of domestic and foreign scholars in the fields of competitive development, entrepreneurship, quasi-markets theories and self- developing organizations. The paper presents the author’s interpretation of the university entrepreneurship as the integrated and systematic process generated by the dramatic changes of socio-economic development, increasing global trends of economy intellectualization, significant proportion of scientific and educational services, and increasing role of modernization in sustaining the state welfare and stability. The university entrepreneurship is regarded as a synthesis of creative, innovative, commercial and managerial activities in the market of scientific and educational services, labor market, industrial and financial markets. The interrelation of economic and social aspects of university business is revealed including the links between the government, universities, scientific educational institutions, business community, households and other subjects of educational service market. The application of the main theoretical principles of the research concerning the higher school business vector is demonstrated by the practical activity of the Russian Vocational Pedagogical University. 

  4. The Innovation Clusters in the Developments by the Scandinavian School of Cluster Theory

    Directory of Open Access Journals (Sweden)

    Onipko Tetiana A.


    Full Text Available The article generalizes and analyzes the developments by the Scandinavian School of cluster theory (scientists from Sweden, Norway and Denmark on innovative clusters. It has been found that the Scandinavian scientists considered innovative clusters as an integral component of both the regional and the national innovation systems. It has been clarified that the efficiency of an innovative cluster depends largely on the «knowledge base». It was emphasized that innovative clusters, by facilitating interactive training and generating new ideas, stimulate the development of the «economy of training». It has been determined that the coordinating structures of innovative clusters are the institutions of cooperation that facilitate interaction between enterprises, scientific centres, and authorities. It has been specified that innovative clusters contribute to the emerging of benefits for participants, including the growing opportunities for innovation, improved conditions for establishing a business, and increased productivity. It has been concluded that the development of the inner environment of an innovative cluster depends largely on its relationships to the external environment.

  5. Realizing an Optimization Approach Inspired from Piaget’s Theory on Cognitive Development

    Directory of Open Access Journals (Sweden)

    Utku Kose


    Full Text Available The objective of this paper is to introduce an artificial intelligence based optimization approach, which is inspired from Piaget’s theory on cognitive development. The approach has been designed according to essential processes that an individual may experience while learning something new or improving his / her knowledge. These processes are associated with the Piaget’s ideas on an individual’s cognitive development. The approach expressed in this paper is a simple algorithm employing swarm intelligence oriented tasks in order to overcome single-objective optimization problems. For evaluating effectiveness of this early version of the algorithm, test operations have been done via some benchmark functions. The obtained results show that the approach / algorithm can be an alternative to the literature in terms of single-objective optimization.The authors have suggested the name: Cognitive Development Optimization Algorithm (CoDOA for the related intelligent optimization approach.

  7. The SIMRAND methodology: Theory and application for the simulation of research and development projects (United States)

    Miles, R. F., Jr.


    A research and development (R&D) project often involves a number of decisions that must be made concerning which subset of systems or tasks are to be undertaken to achieve the goal of the R&D project. To help in this decision making, SIMRAND (SIMulation of Research ANd Development Projects) is a methodology for the selection of the optimal subset of systems or tasks to be undertaken on an R&D project. Using alternative networks, the SIMRAND methodology models the alternative subsets of systems or tasks under consideration. Each path through an alternative network represents one way of satisfying the project goals. Equations are developed that relate the system or task variables to the measure of reference. Uncertainty is incorporated by treating the variables of the equations probabilistically as random variables, with cumulative distribution functions assessed by technical experts. Analytical techniques of probability theory are used to reduce the complexity of the alternative networks. Cardinal utility functions over the measure of preference are assessed for the decision makers. A run of the SIMRAND Computer I Program combines, in a Monte Carlo simulation model, the network structure, the equations, the cumulative distribution functions, and the utility functions.

  8. Theory of the development of curved barbs and their effects on feather morphology. (United States)

    Feo, Teresa J; Simon, Emma; Prum, Richard O


    Feathers exhibit an extraordinary diversity of shapes, which are used by birds to accomplish a diverse set of functions. Pennaceous feathers have a double branched morphology that develops from a tube of epidermis, and variation in branch geometry determines feather shape. Feather development is both complex (i.e., a simple developmental modification can have multiple effects on mature feather shape), and redundant (i.e., different developmental modifications can create the same shape). Due to this, it is not readily apparent how different feather shapes develop. In many feathers, barbs are not straight, but instead curve in toward, or away, from the feather tip. Barb curvature can affect the shape of mature feathers but the development of curved barbs is unknown. Previous research has hypothesized that barb curvature could develop either during the helical growth of barb ridges in the tubular feather germ, or during barb angle expansion as the feather unfurls from the sheath. To better understand the development of curved barbs and their effects on mature feathers we present a theoretical model of curved barb development and test the model with empirical investigations of feathers. We find that curved barbs affect many aspects of feather morphology including vane width, barb length, and barb spacing. In real feathers, curved barbs can develop both during helical barb ridge growth and during barb angle expansion, with most of the observed curvature due to barb angle expansion. Our results demonstrate that barb angle expansion as a feather unfurls from the sheath is a complex and dynamic process that plays an important role in determining the shape and structure of mature feathers. Curved barbs create heterogeneity in barb geometry within the feather vane, which could have important implications for aerodynamic function and the development of within feather pigmentation patterns.

  9. Aligning Theory and Design: The Development of an Online Learning Intervention to Teach Evidence-based Practice for Maximal Reach. (United States)

    Delagran, Louise; Vihstadt, Corrie; Evans, Roni


    Online educational interventions to teach evidence-based practice (EBP) are a promising mechanism for overcoming some of the barriers to incorporating research into practice. However, attention must be paid to aligning strategies with adult learning theories to achieve optimal outcomes. We describe the development of a series of short self-study modules, each covering a small set of learning objectives. Our approach, informed by design-based research (DBR), involved 6 phases: analysis, design, design evaluation, redesign, development/implementation, and evaluation. Participants were faculty and students in 3 health programs at a complementary and integrative educational institution. We chose a reusable learning object approach that allowed us to apply 4 main learning theories: events of instruction, cognitive load, dual processing, and ARCS (attention, relevance, confidence, satisfaction). A formative design evaluation suggested that the identified theories and instructional approaches were likely to facilitate learning and motivation. Summative evaluation was based on a student survey (N=116) that addressed how these theories supported learning. Results suggest that, overall, the selected theories helped students learn. The DBR approach allowed us to evaluate the specific intervention and theories for general applicability. This process also helped us define and document the intervention at a level of detail that covers almost all the proposed Guideline for Reporting Evidence-based practice Educational intervention and Teaching (GREET) items. This thorough description will facilitate the interpretation of future research and implementation of the intervention. Our approach can also serve as a model for others considering online EBP intervention development.

  10. A mandala of faculty development: using theory-based evaluation to explore contexts, mechanisms and outcomes. (United States)

    Onyura, Betty; Ng, Stella L; Baker, Lindsay R; Lieff, Susan; Millar, Barbara-Ann; Mori, Brenda


    Demonstrating the impact of faculty development, is an increasingly mandated and ever elusive goal. Questions have been raised about the adequacy of current approaches. Here, we integrate realist and theory-driven evaluation approaches, to evaluate an intensive longitudinal program. Our aim is to elucidate how faculty development can work to support a range of outcomes among individuals and sub-systems in the academic health sciences. We conducted retrospective framework analysis of qualitative focus group data gathered from 79 program participants (5 cohorts) over a 10-year period. Additionally, we conducted follow-up interviews with 15 alumni. We represent the interactive relationships among contexts, mechanisms, and outcomes as a "mandala" of faculty development. The mandala illustrates the relationship between the immediate program context, and the broader institutional context of academic health sciences, and identifies relevant change mechanisms. Four primary mechanisms were collaborative-reflection, self-reflection and self-regulation, relationship building, and pedagogical knowledge acquisition. Individual outcomes, including changed teaching practices, are described. Perhaps most interestingly, secondary mechanisms-psychological and structural empowerment-contributed to institutional outcomes through participants' engagement in change leadership in their local contexts. Our theoretically informed evaluation approach models how faculty development, situated in appropriate institutional contexts, can trigger mechanisms that yield a range of benefits for faculty and their institutions. The adopted methods hold potential as a way to demonstrate the often difficult-to-measure outcomes of educational programs, and allow for critical examination as to how and whether faculty development programs can accomplish their espoused goals.

  11. Development and Evaluation of the Brief Sexual Openness Scale-A Construal Level Theory Based Approach. (United States)

    Chen, Xinguang; Wang, Yan; Li, Fang; Gong, Jie; Yan, Yaqiong


    Obtaining reliable and valid data on sensitive questions represents a longstanding challenge for public health, particularly HIV research. To overcome the challenge, we assessed a construal level theory (CLT)-based novel method. The method was previously established and pilot-tested using the Brief Sexual Openness Scale (BSOS). This scale consists of five items assessing attitudes toward premarital sex, multiple sexual partners, homosexuality, extramarital sex, and commercial sex, all rated on a standard 5-point Likert scale. In addition to self-assessment, the participants were asked to assess rural residents, urban residents, and foreigners. The self-assessment plus the assessment of the three other groups were all used as subconstructs of one latent construct: sexual openness. The method was validated with data from 1,132 rural-to-urban migrants (mean age = 32.5, SD = 7.9; 49.6% female) recruited in China. Consistent with CLT, the Cronbach alpha of the BSOS as a conventional tool increased with social distance, from .81 for self-assessment to .97 for assessing foreigners. In addition to a satisfactory fit of the data to a one-factor model (CFI = .94, TLI = .93, RMSEA = .08), a common factor was separated from the four perspective factors (i.e., migrants' self-perspective and their perspectives of rural residents, urban residents and foreigners) through a trifactor modeling analysis (CFI = .95, TLI = .94, RMSEA = .08). Relative to its conventional form, CTL-based BSOS was more reliable (alpha: .96 vs .81) and valid in predicting sexual desire, frequency of dating, age of first sex, multiple sexual partners and STD history. This novel technique can be used to assess sexual openness, and possibly other sensitive questions among Chinese domestic migrants.

  12. A systems theory approach to career development: Exploring factors that affect science as a career choice (United States)

    Liskey, Brian K.

    This research project was designed to examine the factors that affect students' choice in a career. Specifically, the factors of (a) achievement, (b) interest, (c) self-efficacy, (d) perceived preparation for a career, and (e) being informed about a career will be under investigation. Of key importance to the study is how these factors can affect a student's perception about choosing a science career. A quantitative analysis of secondary data from the 2006 and 2009 Program for International Student Assessment (PISA) international assessment and attitudinal questionnaire provided data on student perceptions and aptitude in science. The sample from PISA included over 400,000 15 year-old students from 57 countries. From the 57 countries, 30 countries, comprised by Organization for Economic and Cooperative Development (OECD), were isolated for analysis. Within this group of 30, 11 were selected for comparison based on their questionnaire response to expectations for a career in science at age 30. The Institute for Educational Science's, International Data Explorer was utilized to acquire and analyze data from the 2006 and 2009 PISA international tests and questionnaires to determine significance between scaled scores and PISA indices. Variables were chosen as factors affecting student's perception on various systems outlined by the Systems Theory of Career Development (Patton & McMahon, 1997) and the Systems Theory of Career Development Framework (Patton & McMahon, 1999). Four country groups were established based on student responses to question 30a from the 2006 PISA attitudinal questionnaire, which asks what career students expected to have at age 30. The results from comparing country groups showed that countries in Group A, which showed the highest values for students expecting a career in science, also had the highest average values for achievement on the PISA science literacy assessment. Likewise, countries that had the lowest values for expecting a career in

  20. Developing a theory of change for a community-based response to illegal wildlife trade. (United States)

    Biggs, Duan; Cooney, Rosie; Roe, Dilys; Dublin, Holly T; Allan, James R; Challender, Dan W S; Skinner, Diane


    The escalating illegal wildlife trade (IWT) is one of the most high-profile conservation challenges today. The crisis has attracted over US$350 million in donor and government funding in recent years, primarily directed at increased enforcement. There is growing recognition among practitioners and policy makers of the need to engage rural communities that neighbor or live with wildlife as key partners in tackling IWT. However, a framework to guide such community engagement is lacking. We developed a theory of change (ToC) to guide policy makers, donors, and practitioners in partnering with communities to combat IWT. We identified 4 pathways for community-level actions: strengthen disincentives for illegal behavior, increase incentives for wildlife stewardship, decrease costs of living with wildlife, and support livelihoods that are not related to wildlife. To succeed the pathways, all require strengthening of enabling conditions, including capacity building, and of governance. Our ToC serves to guide actions to tackle IWT and to inform the evaluation of policies. Moreover, it can be used to foster dialogue among IWT stakeholders, from local communities to governments and international donors, to develop a more effective, holistic, and sustainable community-based response to the IWT crisis. © 2016 The Authors.

  1. Theory of mind and language development in Japanese children with hearing loss. (United States)

    Fujino, Hiroshi; Fukushima, Kunihiro; Fujiyoshi, Akie


    This study investigates the development of theory of mind (ToM) in Japanese children with hearing loss (HL) and its relationship with language abilities using the data of a large sample size. Participants were 369 children with HL, ranging from 4 to 12 years of age. The mean hearing level of the better ear was 100.7 dB. A "change in location"-type false belief task similar to the "Sally-Anne test" was given to the participants. The pass rates for the false belief task were in the 20% range for 4 to 6-year-olds, 35.6% for 7-year-olds, 47.6% for 8-year-olds, and 63.6% for 9-year-olds. However, no children, even 12-year-olds, achieved a pass rate of 70%. A logistic regression analysis showed that the significant independent predictors of the false belief task performance were vocabulary age and syntactic comprehension level, and chronological age, hearing level, syntactic production level, and nonverbal intelligence were excluded. The results demonstrate that there is a delay in the development of ToM in Japanese children with HL. This finding is consistent with findings in English-speaking countries. Additionally, it is suggested that language abilities play an important role in the acquisition of ToM for children with HL. Copyright © 2017 Elsevier B.V. All rights reserved.

  2. Theory of the development of alternans in the heart during controlled diastolic interval pacing (United States)

    Otani, Niels F.


    The beat-to-beat alternation in action potential durations (APDs) in the heart, called APD alternans, has been linked to the development of serious cardiac rhythm disorders, including ventricular tachycardia and fibrillation. The length of the period between action potentials, called the diastolic interval (DI), is a key dynamical variable in the standard theory of alternans development. Thus, methods that control the DI may be useful in preventing dangerous cardiac rhythms. In this study, we examine the dynamics of alternans during controlled-DI pacing using a series of single-cell and one-dimensional (1D) fiber models of alternans dynamics. We find that a model that combines a so-called memory model with a calcium cycling model can reasonably explain two key experimental results: the possibility of alternans during constant-DI pacing and the phase lag of APDs behind DIs during sinusoidal-DI pacing. We also find that these results can be replicated by incorporating the memory model into an amplitude equation description of a 1D fiber. The 1D fiber result is potentially concerning because it seems to suggest that constant-DI control of alternans can only be effective over only a limited region in space.

  3. Conceptual development of a complete LWR reload design methodology based on generalized perturbation theory

    International Nuclear Information System (INIS)

    White, J.R.


    A new approach for the physics design and analysis of LWR reload cores is developed and demonstrated through several practical applications. The new design philosophy uses first- and second-order response derivatives to predict the important reactor performance characteristics (power peaking, reactivity coefficients, etc.) for any number of possible material configurations (assembly shuffling and burnable poison loadings). The response derivatives are computed using generalized perturbation theory (GPT) techniques. This report describes in detail an idealized GPT-based design system. The idealized system would contain individual modules to generate the required first-order and higher-order sensitivity data. It would also contain at least two major application codes; one for core design optimization and the other for evaluation of several safety parameters of interest in off-normal situations. This ideal system would be fully automated, user-friendly, and quite flexible in its ability to provide a variety of design and analysis capabilities. Information gained form these three studies gives a good foundation for the development of a complete integrated design package

  4. The role of behavioral science theory in development and implementation of public health interventions. (United States)

    Glanz, Karen; Bishop, Donald B


    Increasing evidence suggests that public health and health-promotion interventions that are based on social and behavioral science theories are more effective than those lacking a theoretical base. This article provides an overview of the state of the science of theory use for designing and conducting health-promotion interventions. Influential contemporary perspectives stress the multiple determinants and multiple levels of determinants of health and health behavior. We describe key types of theory and selected often-used theories and their key concepts, including the health belief model, the transtheoretical model, social cognitive theory, and the ecological model. This summary is followed by a review of the evidence about patterns and effects of theory use in health behavior intervention research. Examples of applied theories in three large public health programs illustrate the feasibility, utility, and challenges of using theory-based interventions. This review concludes by identifying cross-cutting themes and important future directions for bridging the divides between theory, practice, and research.

  5. How theory is used and articulated in qualitative research: development of a new typology. (United States)

    Bradbury-Jones, Caroline; Taylor, Julie; Herber, Oliver


    There is a long tradition within qualitative research of theory being central and of critical importance. Qualitative research theory often equates with the methodologies used but this is a complex relationship, plagued by lack of consensus among scholars regarding how theory and methodology are related. This article furthers the debates on how theories are used in qualitative research, how they might influence a study and how they are articulated in publications. The aim is to provide a framework through which the relationship between theory and qualitative research can be understood. We propose a five-point typology on the levels of theoretical visibility, testing this against a range of published research from five key international health, medicine and social science journals. The typology captures a range of visibility--from seemingly absent through to highly visible and applied throughout. There was a clear gradient in this assessment--only a minority appeared to use theory consistently throughout a study. We outline several challenges to consistently applying theory in qualitative research and suggest potential solutions. This article is based on the argument that lack of theory in qualitative research undermines its quality. The typology is offered to assist researchers in applying theory in their own research and critiquing its use in the work of others. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Understanding links between behaviour change techniques (BCTs) and mechanisms of action (the processes through which they affect behaviour) helps inform the systematic development of behaviour change interventions. This research aims to develop and test a methodology for linking BCTs to their mechanisms of action. Study 1 (published explicit links): Hypothesised links between 93 BCTs (from the 93-item BCT taxonomy, BCTTv1) and mechanisms of action will be identified from published interventions and their frequency, explicitness and precision documented. Study 2 (expert-agreed explicit links): Behaviour change experts will identify links between 61 BCTs and 26 mechanisms of action in a formal consensus study. Study 3 (integrated matrix of explicit links): Agreement between studies 1 and 2 will be evaluated and a new group of experts will discuss discrepancies. An integrated matrix of BCT-mechanism of action links, annotated to indicate strength of evidence, will be generated. Study 4 (published implicit links): To determine whether groups of co-occurring BCTs can be linked to theories, we will identify groups of BCTs that are used together from the study 1 literature. A consensus exercise will be used to rate strength of links between groups of BCT and theories. A formal methodology for linking BCTs to their hypothesised mechanisms of action can contribute to the development and evaluation of behaviour change interventions. This research is a step towards developing a behaviour change 'ontology', specifying relations between BCTs, mechanisms of action, modes of delivery, populations, settings and types of behaviour.

  7. Womens' opinions on intrapartal care: development of a theory-based questionnaire. (United States)

    Wilde-Larsson, Bodil; Larsson, Gerry; Kvist, Linda J; Sandin-Bojö, Ann-Kristin


    To develop a patient questionnaire specific to intrapartal care, based on the theoretical foundation of the general instrument Quality from the Patient's Perspective (QPP). Existing general patient questionnaires do not take intrapartal care aspects fully into account, and available intrapartal-specific patient questionnaires tend to have a weak theoretical foundation. A cross-sectional, nationwide study carried out during a two-week period in 2007 at Swedish maternity units. An intrapartal-specific QPP-questionnaire (QPP-I) was developed by combining a selection of 22 items from the short and long versions of the QPP with 10 newly constructed items. Responses were obtained from 739 women (63% response rate). The dimensionality of the QPP-I was assessed using structural equation modelling (a nested factor model). Non-parametric statistics were used for subgroup comparisons. A nested model with a general factor including all 32 items and 10 subordinate factors was developed. Most scales had acceptable reliability coefficients (0.73-0.93), and a meaningful pattern of subgroup differences was obtained. The QPP-I is theory based and has its roots in a patient perspective. It was developed using a nationwide sample of Swedish women receiving intrapartal care, and an advanced statistical method was used. The outcome of this initial empirical trial was promising but needs to be tested in different countries and cultures. By combining womens' responses on perceived reality and subjective importance ascribed to the various aspects of care measured, the QPP-I offers the care provider better guidelines on which elements to focus quality improvement work on, than would be the case if only a rank order of perceived reality ratings was available.

  8. The Role of Percolation Theory in Developing Next Generation Smart Nanomaterials (United States)

    Simien, Daneesh


    The incorporation of small volume fractions of nanoscale graphitic particles into varied base materials has been explored across fields ranging from automotive to aerospace to commercial plastics, with the goal of utilizing their enhanced thermal conductivity, electrical conductivity or mechanical strength. Percolation theory has emerged as a useful tool to aid in mapping and predicting the enhancement of properties based on the size and conductivity of incorporated single-walled carbon nanotubes relative to their less conductive base materials. These tools can aid researchers in the development of next generation smart nanomaterials. In this paper, we discuss the use of homogeneous fractions of length- or chirality-sorted single-walled carbon nanotubes (SWNTs) which are incorporated into thin film networks, and cement composites, and are evaluated in terms of their conductivity, mechanical properties and noise spectrum at critical percolation. We demonstrate that, near the percolation threshold, the conductivity of these highly characterized SWNT films exhibits a power law dependence on the network geometrical parameters. We also present our findings on the development of incorporated thin film SWNTs for the development of sensing technology for novel non-destructive failure diagnostic applications. SWNTs are able to be used as benign inclusions, capable of active sensing, when incorporated into cement-based composites for the purpose of detecting crack initiation. As such, we investigate the use of homogeneous length-sorted SWNTs that are randomly distributed in percolated networks capable of being an internal responsive net mechanism. Our findings demonstrate increased microstructure sensitivity of our networks for our shorter length nanotubes near their critical percolation threshold. This shows promise for the development of even more sensitive, embedded piezo-resistive SWNT-based sensors for preemptive failure detection technology.

  9. Maize sugary enhancer1 (se1) is a presence-absence variant of a previously uncharacterized gene and development of educational videos to raise the profile of plant breeding and improve curricula (United States)

    Haro von Mogel, Karl J.

    Carbohydrate metabolism is a biologically, economically, and culturally important process in crop plants. Humans have selected many crop species such as maize (Zea mays L.) in ways that have resulted in changes to carbohydrate metabolic pathways, and understanding the underlying genetics of this pathway is therefore exceedingly important. A previously uncharacterized starch metabolic pathway mutant, sugary enhancer1 (se1), is a recessive modifier of sugary1 (su1) sweet corn that increases the sugar content while maintaining an appealing creamy texture. This allele has been incorporated into many sweet corn varieties since its discovery in the 1970s, however, testing for the presence of this allele has been difficult. A genetic stock was developed that allowed the presence of se1 to be visually scored in segregating ears, which were used to genetically map se1 to the deletion of a single gene model located on the distal end of the long arm of chromosome 2. An analysis of homology found that this gene is specific to monocots, and the gene is expressed in the endosperm and developing leaf. The se1 allele increased water soluble polysaccharide (WSP) and decreased amylopectin in maize endosperm, but there was no overall effect on starch content in mature leaves due to se1. This discovery will lead to a greater understanding of starch metabolism, and the marker developed will assist in breeding. There is a present need for increased training for plant breeders to meet the growing needs of the human population. To raise the profile of plant breeding among young students, a series of videos called Fields of Study was developed. These feature interviews with plant breeders who talk about what they do as plant breeders and what they enjoy about their chosen profession. To help broaden the education of students in college biology courses, and assist with the training of plant breeders, a second video series, Pollination Methods was developed. Each video focuses on one or two

  10. The Father Friendly Initiative within Families: Using a logic model to develop program theory for a father support program. (United States)

    Gervais, Christine; de Montigny, Francine; Lacharité, Carl; Dubeau, Diane


    The transition to fatherhood, with its numerous challenges, has been well documented. Likewise, fathers' relationships with health and social services have also begun to be explored. Yet despite the problems fathers experience in interactions with healthcare services, few programs have been developed for them. To explain this, some authors point to the difficulty practitioners encounter in developing and structuring the theory of programs they are trying to create to promote and support father involvement (Savaya, R., & Waysman, M. (2005). Administration in Social Work, 29(2), 85), even when such theory is key to a program's effectiveness (Chen, H.-T. (2005). Practical program evaluation. Thousand Oaks, CA: Sage Publications). The objective of the present paper is to present a tool, the logic model, to bridge this gap and to equip practitioners for structuring program theory. This paper addresses two questions: (1) What would be a useful instrument for structuring the development of program theory in interventions for fathers? (2) How would the concepts of a father involvement program best be organized? The case of the Father Friendly Initiative within Families (FFIF) program is used to present and illustrate six simple steps for developing a logic model that are based on program theory and demonstrate its relevance.

    Scaling up mental healthcare through integration into primary care remains the main strategy to address the extensive unmet mental health need in low-income countries. For integrated care to achieve its goal, a clear understanding of the organisational processes that can promote and hinder the integration and delivery of mental health care is essential. Theory of Change (ToC), a method employed in the planning, implementation and evaluation of complex community initiatives, is an innovative approach that has the potential to assist in the development of a comprehensive mental health care plan (MHCP), which can inform the delivery of integrated care. We used the ToC approach to develop a MHCP in a rural district in Ethiopia. The work was part of a cross-country study, the Programme for Improving Mental Health Care (PRIME) which focuses on developing evidence on the integration of mental health in to primary care. An iterative ToC development process was undertaken involving multiple workshops with stakeholders from diverse backgrounds that included representatives from the community, faith and traditional healers, community associations, non-governmental organisations, Zonal, Regional and Federal level government offices, higher education institutions, social work and mental health specialists (psychiatrists and psychiatric nurses). The objective of this study is to report the process of implementing the ToC approach in developing mental health care plan. A total of 46 persons participated in four ToC workshops. Four critical path dimensions were identified: community, health facility, administrative and higher level care organisation. The ToC participants were actively engaged in the process and the ToC encouraged strong commitment among participants. Key opportunities and barriers to implementation and how to overcome these were suggested. During the workshops, a map incorporating the key agreed outcomes and outcome indicators was developed and finalized later

  14. Using complexity theory to develop a student-directed interprofessional learning activity for 1220 healthcare students. (United States)

    Jorm, Christine; Nisbet, Gillian; Roberts, Chris; Gordon, Christopher; Gentilcore, Stacey; Chen, Timothy F


    More and better interprofessional practice is predicated to be necessary to deliver good care to the patients of the future. However, universities struggle to create authentic learning activities that enable students to experience the dynamic interprofessional interactions common in healthcare and that can accommodate large interprofessional student cohorts. We investigated a large-scale mandatory interprofessional learning (IPL) activity for health professional students designed to promote social learning. A mixed methods research approach determined feasibility, acceptability and the extent to which student IPL outcomes were met. We developed an IPL activity founded in complexity theory to prepare students for future practice by engaging them in a self-directed (self-organised) learning activity with a diverse team, whose assessable products would be emergent creations. Complicated but authentic clinical cases (n = 12) were developed to challenge student teams (n = 5 or 6). Assessment consisted of a written management plan (academically marked) and a five-minute video (peer marked) designed to assess creative collaboration as well as provide evidence of integrated collective knowledge; the cohesive patient-centred management plan. All students (including the disciplines of diagnostic radiology, exercise physiology, medicine, nursing, occupational therapy, pharmacy, physiotherapy and speech pathology), completed all tasks successfully. Of the 26 % of students who completed the evaluation survey, 70 % agreed or strongly agreed that the IPL activity was worthwhile, and 87 % agreed or strongly agreed that their case study was relevant. Thematic analysis found overarching themes of engagement and collaboration-in-action suggesting that the IPL activity enabled students to achieve the intended learning objectives. Students recognised the contribution of others and described negotiation, collaboration and creation of new collective knowledge after working

  15. String theory or field theory?

    International Nuclear Information System (INIS)

    Marshakov, Andrei V


    The status of string theory is reviewed, and major recent developments - especially those in going beyond perturbation theory in the string theory and quantum field theory frameworks - are analyzed. This analysis helps better understand the role and place of string theory in the modern picture of the physical world. Even though quantum field theory describes a wide range of experimental phenomena, it is emphasized that there are some insurmountable problems inherent in it - notably the impossibility to formulate the quantum theory of gravity on its basis - which prevent it from being a fundamental physical theory of the world of microscopic distances. It is this task, the creation of such a theory, which string theory, currently far from completion, is expected to solve. In spite of its somewhat vague current form, string theory has already led to a number of serious results and greatly contributed to progress in the understanding of quantum field theory. It is these developments which are our concern in this review. (reviews of topical problems)

  18. Scale development with small samples: a new application of longitudinal item response theory. (United States)

    Houts, Carrie R; Morlock, Robert; Blum, Steven I; Edwards, Michael C; Wirth, R J


    Measurement development in hard-to-reach populations can pose methodological challenges. Item response theory (IRT) is a useful statistical tool, but often requires large samples. We describe the use of longitudinal IRT models as a pragmatic approach to instrument development when large samples are not feasible. The statistical foundations and practical benefits of longitudinal IRT models are briefly described. Results from a simulation study are reported to demonstrate the model's ability to recover the generating measurement structure and parameters using a range of sample sizes, number of items, and number of time points. An example using early-phase clinical trial data in a rare condition demonstrates these methods in practice. Simulation study results demonstrate that the longitudinal IRT model's ability to recover the generating parameters rests largely on the interaction between sample size and the number of time points. Overall, the model performs well even in small samples provided a sufficient number of time points are available. The clinical trial data example demonstrates that by using conditional, longitudinal IRT models researchers can obtain stable estimates of psychometric characteristics from samples typically considered too small for rigorous psychometric modeling. Capitalizing on repeated measurements, it is possible to estimate psychometric characteristics for an assessment even when sample size is small. This allows researchers to optimize study designs and have increased confidence in subsequent comparisons using scores obtained from such models. While there are limitations and caveats to consider when using these models, longitudinal IRT modeling may be especially beneficial when developing measures for rare conditions and diseases in difficult-to-reach populations.

  19. F.F. Bosworth: A historical analysis of his ministry development using social cognitive career theory

    Directory of Open Access Journals (Sweden)

    Roscoe Barnes


    Full Text Available The purpose of this article was to discuss the findings related to research on the life history of Fred Francis Bosworth (1877�1958. This article explored his life story and critically analysed the influential factors that may have contributed to his success in the ministry. It seeks to answer the question: �How did Bosworth develop into a famous healing evangelist?� The historical case study method was used as the research design. It also employed a variant of Social Cognitive Career Theory (SCCT, which suggests that a person�s career choice can be determined by his or her self-efficacy beliefs, goals and expected outcomes. This article is the first to offer a critical analysis of Bosworth�s entire life and ministry and is also the first to use the concepts of SCCT to show how his adulthood success may have been influenced by the experiences of his childhood and youth. This article argued that several factors played a critical role in Bosworth�s development. Although Bosworth and others have attributed his success primarily to his Pentecostal experience, this study contends that his childhood, as well as secular and business experiences played a more important role than has been reported in the literature. Furthermore, this article showed that Bosworth�s path to success can be understood through the elements of SCCT. Through SCCT, one can see how Bosworth developed an interest in the healing ministry, how he chose to pursue the ministry as a career, and how he performed and set goals as an evangelist.

  20. Executive Function in Previously Institutionalized Children. (United States)

    Merz, Emily C; Harlé, Katia M; Noble, Kimberly G; McCall, Robert B


    In studies of children adopted from institutions, being raised in an institution has been associated consistently with an increased risk of persistent cognitive, academic, and social-emotional problems. These findings raise questions about the neurocognitive mechanisms that contribute to these negative outcomes. Theory and models based on studies of animals indicate that development of the prefrontal cortex (PFC) and executive function (EF) may be particularly susceptible to environmental influences during early childhood. In this article, we review recent studies of postinstitutionalized children that examined EF components such as inhibitory control, working memory, shifting, and planning. We then describe emerging research on the structure and function of the PFC. Converging evidence suggests both EF difficulties and alterations in development of the PFC following early institutionalization. We conclude by discussing possible explanations for these findings and implications for prevention and intervention, and by offering suggestions for ongoing research.
