What neuropsychology tells us about human tool use? The four constraints theory (4CT): mechanics, space, time, and effort.

PubMed

Osiurak, François

2014-06-01

Our understanding of human tool use comes mainly from neuropsychology, particularly from patients with apraxia or action disorganization syndrome. However, there is no integrative, theoretical framework explaining what these neuropsychological syndromes tell us about the cognitive/neural bases of human tool use. The goal of the present article is to fill this gap, by providing a theoretical framework for the study of human tool use: The Four Constraints Theory (4CT). This theory rests on two basic assumptions. First, everyday tool use activities can be formalized as multiple problem situations consisted of four distinct constraints (mechanics, space, time, and effort). Second, each of these constraints can be solved by the means of a specific process (technical reasoning, semantic reasoning, working memory, and simulation-based decision-making, respectively). Besides presenting neuropsychological evidence for 4CT, this article shall address epistemological, theoretical and methodological issues I will attempt to resolve. This article will discuss how 4CT diverges from current cognitive models about several widespread hypotheses (e.g., notion of routine, direct and automatic activation of tool knowledge, simulation-based tool knowledge).

[Theoretical and methodological uses of research in Social and Human Sciences in Health].

PubMed

Deslandes, Suely Ferreira; Iriart, Jorge Alberto Bernstein

2012-12-01

The current article aims to map and critically reflect on the current theoretical and methodological uses of research in the subfield of social and human sciences in health. A convenience sample was used to select three Brazilian public health journals. Based on a reading of 1,128 abstracts published from 2009 to 2010, 266 articles were selected that presented the empirical base of research stemming from social and human sciences in health. The sample was classified thematically as "theoretical/ methodological reference", "study type/ methodological design", "analytical categories", "data production techniques", and "analytical procedures". We analyze the sample's emic categories, drawing on the authors' literal statements. All the classifications and respective variables were tabulated in Excel. Most of the articles were self-described as qualitative and used more than one data production technique. There was a wide variety of theoretical references, in contrast with the almost total predominance of a single type of data analysis (content analysis). In several cases, important gaps were identified in expounding the study methodology and instrumental use of the qualitative research techniques and methods. However, the review did highlight some new objects of study and innovations in theoretical and methodological approaches.

Nurses' tending instinct as a conduit for men's access to mental health counseling.

PubMed

Smith, Jeffrey M; Robertson, Steve

2006-06-01

No article has been found melding the phenomenon of nurses' tending instinct and men's mental health counseling access. This theoretical article presents nurses' tending instinct as a viable rationale to support men in utilizing mental health counseling services. Nurses can be the conduit that assists men in accessing mental health counseling when the need arises. An amalgamation of related topics, including nurses' tending instinct, men's illness/injury/disease profile, psychological medicine, and counselor skills, were forged together to unify this innovative theoretical consideration. Implications for nursing practice also were explored.

An information-theoretical perspective on weighted ensemble forecasts

NASA Astrophysics Data System (ADS)

Weijs, Steven V.; van de Giesen, Nick

2013-08-01

This paper presents an information-theoretical method for weighting ensemble forecasts with new information. Weighted ensemble forecasts can be used to adjust the distribution that an existing ensemble of time series represents, without modifying the values in the ensemble itself. The weighting can, for example, add new seasonal forecast information in an existing ensemble of historically measured time series that represents climatic uncertainty. A recent article in this journal compared several methods to determine the weights for the ensemble members and introduced the pdf-ratio method. In this article, a new method, the minimum relative entropy update (MRE-update), is presented. Based on the principle of minimum discrimination information, an extension of the principle of maximum entropy (POME), the method ensures that no more information is added to the ensemble than is present in the forecast. This is achieved by minimizing relative entropy, with the forecast information imposed as constraints. From this same perspective, an information-theoretical view on the various weighting methods is presented. The MRE-update is compared with the existing methods and the parallels with the pdf-ratio method are analysed. The paper provides a new, information-theoretical justification for one version of the pdf-ratio method that turns out to be equivalent to the MRE-update. All other methods result in sets of ensemble weights that, seen from the information-theoretical perspective, add either too little or too much (i.e. fictitious) information to the ensemble.

I-DECIDE: An Online Intervention Drawing on the Psychosocial Readiness Model for Women Experiencing Domestic Violence.

PubMed

Tarzia, Laura; Murray, Elizabeth; Humphreys, Cathy; Glass, Nancy; Taft, Angela; Valpied, Jodie; Hegarty, Kelsey

2016-01-01

Domestic violence (DV) perpetrated by men against women is a pervasive global problem with significant physical and emotional consequences. Although some face-to-face interventions in health care settings have shown promise, there are barriers to disclosure to health care practitioners and women may not be ready to access or accept help, reducing uptake. Similar to the mental health field, interventions from clinical practice can be adapted to be delivered by technology. This article outlines the theoretical and conceptual development of I-DECIDE, an online healthy relationship tool and safety decision aid for women experiencing DV. The article explores the use of the Psychosocial Readiness Model (PRM) as a theoretical framework for the intervention and evaluation. This is a theoretical article drawing on current theory and literature around health care and online interventions for DV. The article argues that the Internet as a method of intervention delivery for DV might overcome many of the barriers present in health care settings. Using the PRM as a framework for an online DV intervention may help women on a pathway to safety and well-being for themselves and their children. This hypothesis will be tested in a randomized, controlled trial in 2015/2016. This article highlights the importance of using a theoretical model in intervention development and evaluation.

The status of the concept of 'phoneme' in psycholinguistics.

PubMed

Uppstad, Per Henning; Tønnessen, Finn Egil

2010-10-01

The notion of the phoneme counts as a break-through of modern theoretical linguistics in the early twentieth century. It paved the way for descriptions of distinctive features at different levels in linguistics. Although it has since then had a turbulent existence across altering theoretical positions, it remains a powerful concept of a fundamental unit in spoken language. At the same time, its conceptual status remains highly unclear. The present article aims to clarify the status of the concept of 'phoneme' in psycholinguistics, based on the scientific concepts of description, understanding and explanation. Theoretical linguistics has provided mainly descriptions. The ideas underlying this article are, first, that these descriptions may not be directly relevant to psycholinguistics and, second, that psycholinguistics in this sense is not a sub-discipline of theoretical linguistics. Rather, these two disciplines operate with different sets of features and with different orientations when it comes to the scientific concepts of description, understanding and explanation.

Advancing further the history of Soviet psychology: moving forward from dominant representations in Western and Soviet psychology.

PubMed

González Rey, Fernando L

2014-02-01

This article discusses the works of some Soviet scholars of psychology, their theoretical positions, and the times within which their works were developed. Dominant representations of Soviet psychology and some of the main Soviet authors are revisited in the light of a blending of facts actively associated with their emergence in both Soviet and Western psychology. From the beginning, Soviet psychology was founded upon Marxism. However, the ways by which that psychology pretended to become Marxist in its philosophical basis were diverse and often contradictory. Other philosophical and theoretical positions also influenced Soviet psychologists. Different moments of that contradictory process are discussed in this article, and through this, I bring to light their interrelations and the consequences for the development of Soviet psychology. This article reinterprets several myths found within Soviet psychology, in which different theoretical representations have become institutionalized for long periods in both Soviet and Western psychology. Particular attention is given to identifying the conditions that presented Vygotsky, Luria, and Leontiev as part of the same paradigm, and which paved the way for a perception of Leontiev and his group as paralleling Vygotsky's importance among American psychologists. Many of the sources that are used in this article were published in Soviet psychology only after the 1970s. Unlike the different and interesting works that began to appear on diverse trends in Soviet psychology, this article details in depth the articulation of topics and questions that still now are presented as different chapters in the analysis of Soviet psychology.

Theoretical integration and the psychology of sport injury prevention.

PubMed

Chan, Derwin King-Chung; Hagger, Martin S

2012-09-01

Integrating different theories of motivation to facilitate or predict behaviour change has received an increasing amount of attention within the health, sport and exercise science literature. A recent review article in Sports Medicine, by Keats, Emery and Finch presented an integrated model using two prominent theories in social psychology, self-determination theory (SDT) and the theory of planned behaviour (TPB), aimed at explaining and enhancing athletes' adherence to sport injury prevention. While echoing their optimistic views about the utility of these two theories to explain adherence in this area and the virtues of theoretical integration, we would like to seize this opportunity to clarify several conceptual principles arising from the authors' integration of the theories. Clarifying the theoretical assumptions and explaining precisely how theoretical integration works is crucial not only for improving the comprehensiveness of the integrated framework for predicting injury prevention behaviour, but also to aid the design of effective intervention strategies targeting behavioural adherence. In this article, we use the integration of SDT and TPB as an example to demonstrate how theoretical integration can advance the understanding of injury prevention behaviour in sport.

Compressive deformation of a single microcapsule

NASA Astrophysics Data System (ADS)

Liu, K. K.; Williams, D. R.; Briscoe, B. J.

1996-12-01

This paper reports an experimental and theoretical study of the compressive behavior of single microcapsules; that is, liquid-filled cellular entities (approximately 65 μm in diameter) with a thin polymeric membrane wall. An experimental technique which allows the simultaneous measurement of both the compressive displacement and the reaction forces of individual microcapsules deformed between two parallel plates up to a dimensionless approach [(compressive displacement)/(initial particle diameter)] of 60% is described. The corresponding major geometric parameters of the deformed microcapsule, such as central lateral extension as well as the failure phenomena, are reported and recorded through a microscopic visualization system. The elastic modulus, the bursting strength of the membrane, and the pressure difference across the membrane are computed by using a theoretical analysis which is also presented in this paper. This theoretical model, which was developed by Feng and Yang [

Family-focused autism spectrum disorder research: a review of the utility of family systems approaches.

PubMed

Cridland, Elizabeth K; Jones, Sandra C; Magee, Christopher A; Caputi, Peter

2014-04-01

A family member with an autism spectrum disorder presents pervasive and bidirectional influences on the entire family system, suggesting a need for family-focused autism spectrum disorder research. While there has been increasing interest in this research area, family-focused autism spectrum disorder research can still be considered relatively recent, and there are limitations to the existing literature. The purpose of this article is to provide theoretical and methodological directions for future family-focused autism spectrum disorder research. In particular, this article proposes Family Systems approaches as a common theoretical framework for future family-focused autism spectrum disorder research by considering theoretical concepts such as Boundaries, Ambiguous Loss, Resilience and Traumatic Growth. We discuss reasons why these concepts are important to researching families living with autism spectrum disorder and provide recommendations for future research. The potential for research grounded in Family Systems approaches to influence clinical support services is also discussed.

History and theoretical-methodological fundaments of Community Psychology in Ceará.

PubMed

Barros, João Paulo Pereira; Ximenes, Verônica Morais

2016-01-01

In this article we discuss the historical and theoretical-methodological aspects of the Community Psychology that has been developed in the state of Ceará, in northeastern Brazil, based on the praxis initiated by Professor Cezar Wagner de Lima Góis and further developed by the Community Psychology Nucleus (NUCOM) at the Federal University of Ceará. Important aspects of the beginning of this Community Psychology are presented, highlighting its academic and social perspectives. NUCOM is a space for the development of teaching, research, and outreach activities, which allows the systematization and deepening of this proposal for a different Community Psychology. Community Psychology is constituted by five theoretical-methodological marks: Popular Education, Biodance, Carl Rogers' Humanistic Approach, Cultural-Historical Psychology, and Liberation Psychology. Finally, the article describes the methods comprising this proposal for working in communities, which are sustained by pillars such as participation and problematizing dialogue.

Incorporation of massage into psychotherapy: an integrative and conjoint approach.

PubMed

Posadzki, Paul; Parekh-Bhurke, Sheetal

2011-02-01

This article presents the potential integration of psychotherapy and massage when considering the essence of their beneficial effects. The essence of this model of practice is multifaceted, combining principles from anatomy, physiology and neuroscience with psychotherapy to benefit patient care. It has been advocated that possessing multidisciplinary knowledge from these areas of science enhances psychotherapists' holistic care of their depressive patients. A narrative review of the literatures and a qualitative, conceptual synthesis has been performed to create a new theoretical-pragmatic construct. This article introduces the concept of massage practice as a part of psychotherapy practice and presents the potential integration of psychotherapeutic knowledge with clinical decision-making and the management of depressive symptoms. The authors emphasize the usefulness of multi- and interdisciplinary knowledge in the psychotherapeutic process and explain how this knowledge might be extrapolated and incorporated into theoretical and practical settings to benefit depressive patients. The justification for this concept is also presented. The principles set out in this article may be a useful source of information for psychotherapists concerned about their patients' holistic well-being in addition to the psychopathology for which they have sought treatment. Researchers and psychotherapists can obtain valuable and additional knowledge through cross-fertilization of ideas across the arguments presented here.

Vagal activity is quadratically related to prosocial traits, prosocial emotions, and observer perceptions of prosociality.

PubMed

Kogan, Aleksandr; Oveis, Christopher; Carr, Evan W; Gruber, June; Mauss, Iris B; Shallcross, Amanda; Impett, Emily A; van der Lowe, Ilmo; Hui, Bryant; Cheng, Cecilia; Keltner, Dacher

2014-12-01

In the present article, we introduce the quadratic vagal activity-prosociality hypothesis, a theoretical framework for understanding the vagus nerve's involvement in prosociality. We argue that vagus nerve activity supports prosocial behavior by regulating physiological systems that enable emotional expression, empathy for others' mental and emotional states, the regulation of one's own distress, and the experience of positive emotions. However, we contend that extremely high levels of vagal activity can be detrimental to prosociality. We present 3 studies providing support for our model, finding consistent evidence of a quadratic relationship between respiratory sinus arrhythmia--the degree to which the vagus nerve modulates the heart rate--and prosociality. Individual differences in vagal activity were quadratically related to prosocial traits (Study 1), prosocial emotions (Study 2), and outside ratings of prosociality by complete strangers (Study 3). Thus, too much or too little vagal activity appears to be detrimental to prosociality. The present article provides the 1st theoretical and empirical account of the nonlinear relationship between vagal activity and prosociality.

Theory and interpretation in qualitative studies from general practice: Why and how?

PubMed

Malterud, Kirsti

2016-03-01

In this article, I want to promote theoretical awareness and commitment among qualitative researchers in general practice and suggest adequate and feasible theoretical approaches. I discuss different theoretical aspects of qualitative research and present the basic foundations of the interpretative paradigm. Associations between paradigms, philosophies, methodologies and methods are examined and different strategies for theoretical commitment presented. Finally, I discuss the impact of theory for interpretation and the development of general practice knowledge. A scientific theory is a consistent and soundly based set of assumptions about a specific aspect of the world, predicting or explaining a phenomenon. Qualitative research is situated in an interpretative paradigm where notions about particular human experiences in context are recognized from different subject positions. Basic theoretical features from the philosophy of science explain why and how this is different from positivism. Reflexivity, including theoretical awareness and consistency, demonstrates interpretative assumptions, accounting for situated knowledge. Different types of theoretical commitment in qualitative analysis are presented, emphasizing substantive theories to sharpen the interpretative focus. Such approaches are clearly within reach for a general practice researcher contributing to clinical practice by doing more than summarizing what the participants talked about, without trying to become a philosopher. Qualitative studies from general practice deserve stronger theoretical awareness and commitment than what is currently established. Persistent attention to and respect for the distinctive domain of knowledge and practice where the research deliveries are targeted is necessary to choose adequate theoretical endeavours. © 2015 the Nordic Societies of Public Health.

Psychodynamic Emotional Regulation in View of Wolpe's Desensitization Model.

PubMed

Rabinovich, Merav

2016-01-01

The current research belongs to the stream of theoretical integration and establishes a theoretical platform for integrative psychotherapy in anxiety disorders. Qualitative metasynthesis procedures were applied to 40 peer-reviewed psychoanalytic articles involving emotional regulation. The concept of psychodynamic emotional regulation was found to be connected with the categories of desensitization, gradual exposure, containment, and transference. This article presents a model according to which psychoanalytic psychotherapy allows anxiety to be tolerated while following the core principles of systematic desensitization. It is shown that despite the antiresearch image of psychoanalytic psychotherapy, its foundations obey evidence-based principles. The findings imply that anxiety tolerance might be a key goal in which the cumulative wisdom of the different therapies can be used to optimize psychotherapy outcomes.

Ti:sapphire - A theoretical assessment for its spectroscopy

Da Silva, A.; Boschetto, D.; Rax, J. M.; Chériaux, G.

2017-03-01

This article tries to theoretically compute the stimulated emission cross-sections when we know the oscillator strength of a broad material class (dielectric crystals hosting metal-transition impurity atoms). We apply the present approach to Ti:sapphire and check it by computing some emission cross-section curves for both π and σ polarizations. We also set a relationship between oscillator strength and radiative lifetime. Such an approach will allow future parametric studies for Ti:sapphire spectroscopic properties.

DNA in the material world: electrical properties and nano-applications.

PubMed

Triberis, Georgios P; Dimakogianni, Margarita

2009-01-01

Contradictory experimental findings and theoretical interpretations have spurred intense debate over the electrical properties of the DNA double helix. In the present review article the various factors responsible for these divergences are discussed. The enlightenment of this issue could improve long range chemistry of oxidative DNA damage and repair processes, monitoring protein-DNA interactions and possible applications in nano-electronic circuit technology. The update experimental situation concerning measurements of the electrical conductivity is given. The character of the carriers responsible for the electrical conductivity measured in DNA is investigated. A theoretical model for the temperature dependence of the electrical conductivity of DNA is presented, based on microscopic models and percolation theoretical arguments. The theoretical results, excluding or including correlation effects, are applied to recent experimental findings for DNA, considering it as a one dimensional molecular wire. The results indicate that correlation effects are probably responsible for large hopping distances in DNA samples. Other theoretical conductivity models proposed for the interpretation of the responsible transport mechanism are also reviewed. Some of the most known and pioneering works on DNA's nano-applications, future developments and perspectives along with current technological limitations and patents are presented and discussed.

Fifty Years of Mountain Passes: A Perspective on Dan Janzen's Classic Article.

In 1967, Dan Janzen published "Why Mountain Passes Are Higher in the Tropics" in The American Naturalist. Janzen's seminal article has captured the attention of generations of biologists and continues to inspire theoretical and empirical work. The underlying assumptions and derived predictions are broadly synthetic and widely applicable. Consequently, Janzen's "seasonality hypothesis" has proven relevant to physiology, climate change, ecology, and evolution. To celebrate the fiftieth anniversary of this highly influential article, we highlight the past, present, and future of this work and include a unique historical perspective from Janzen himself.

(The following abstract of the original article appeared in record 2018-06787-002.) In 2014 in the Journal of Experimental Psychology: General , we reported 2 studies demonstrating that the diversity of emotions that people experience-as measured by the Shannon-Wiener entropy index-was an independent predictor of mental and physical health, over and above the effect of mean levels of emotion. Brown and Coyne (2017) questioned both our use of Shannon's entropy and our analytic approach. We thank Brown and Coyne for their interest in our research; however, both their theoretical and empirical critiques do not undermine the central theoretical tenets and empirical findings of our research. We present an in-depth examination that reveals that our findings are statistically robust, replicable, and reflect a theoretically grounded phenomenon with real-world implications.

[Acceptance and Commitment Therapy: Theoretical background and practice].

PubMed

Eisenbeck, Nikolett; Schlosser, Károly Kornél; Szondy, Máté; Szabó-Bartha, Anett

The Acceptance and Commitment Therapy (ACT) is one of the modern, so-called third-wave behavioural therapies. Among them the most successful is ACT, both in the number of therapists and respective scientific research. ACT's theoretical and philosophical background is described explicitly and its therapeutic interventions were developed according to this philosophy. Its psychopathological model is based on the idea that mainly the person's regulatory efforts of their own thoughts and feelings lead to psychological problems. That is, the source of human suffering and various psychological problems is the so called psychological inflexibility: control attempts of private events instead of living a life based on personal values and long-term goals. Therefore, clinical work in ACT focuses on the acceptance and defusion of the unwanted inner experiences and on the development of a meaningful life. The present article aims to provide a comprehensive description of ACT in Hungarian: its theoretical background, clinical techniques, and efficacy. At the end of the article, the state of ACT in Hungary will also be briefly discussed.

In a recent article, Hamby advocates the replacement of the "old" Conflict Tactic Scales used to measure physical partner violence (PV) with a new measurement instrument that represents and supports a thesis that gender use of physical PV is asymmetrical rather than symmetrical. This article takes a critical look at the logic, assumptions, arguments, examples, interpretations, and conclusions, presented in Hamby's article, and in some cases disagrees with them. Furthermore, this article uses Hamby's proposals as an opportunity to review and examine core issues in the study of perpetration of physical PV, including gender-related theoretical and methodological issues. © The Author(s) 2015.

Using a theoretical-reflexive approach, this article connects the results of various qualitative studies in social conflict and medical anthropology, in order to investigate how food can be a tool for social transformation in terms of health but also in terms of the dialogue, respect and coexistence among people, groups and communities. In this sense the article presents a first approximation to a new theoretical and methodological approach to food education. In this approach, food adopts a political, sociocultural and participatory perspective that brings us closer to an innovative understanding of the phenomenon of food: not only as an analytic and diagnostic tool, but also as an instrument for health education interventions toward conflict resolution and the promotion of healthier societies overall - nutritionally, but also in terms of equality and social cohesion.

The French connection: some contributions of French-language research in the post-Piagetian era.

PubMed

Larivée, S; Normandeau, S; Parent, S

2000-01-01

This article presents French-speaking researchers' contribution to the field of differential developmental psychology. Following a brief review of key Piagetian ideas pertaining to his conceptualization of individual differences, the core of the article traces methodological and theoretical transformations that were necessary for understanding individual differences within a general theory of cognitive development. On a methodological level, French-speaking researchers went from standardizing Piaget's clinical method to constructing developmental scales and operational tests. On a theoretical level, Reuchlin's writings guided Longeot, and several other French (Lautrey and Bideaud) and Genevan (de Ribaupierre and Rieben) researchers into a scientific quest for a genuine integration of differential and developmental psychology. We present an overview of the pluralistic and multidimensional model of cognitive functioning and development that emerged from the work of the French-Swiss team of researchers. Concluding remarks focus on the actual research agendas of researchers interested in resolving the challenging issue of understanding relationships between inter- and intraindividual differences and general tendencies in cognitive development.

A micro-level model of employment relations and health inequalities.

PubMed

Benach, Joan; Solar, Orielle; Santana, Vilma; Castedo, Antía; Chung, Haejoo; Muntaner, Carles

2010-01-01

Theoretical models are a way of visualizing, in context, the many factors that contribute to inequalities in health. This article presents a model showing the micro-level pathways relating employment and working conditions to health inequalities. A first important (indirect) pathway runs through the unequal distribution of harmful working conditions. Both employment and working conditions tend to be unequally distributed along the same social axes: social class, gender, ethnicity/race, immigration/migration status, territory, and so forth. Underlying mechanisms are exploitation, domination, and discrimination. Material deprivation and economic inequalities constitute a second direct pathway linking (nonstandard) employment conditions to health inequalities. In a third pathway, employment conditions may have an important effect on health inequalities via several psychosocial, behavioral, and physiopathological pathways. Although these several pathways are separated for analytical purposes, they are largely intertwined and, ideally, should be studied in an integrated way. The theoretical model presented in this article serves three main purposes: providing analytical clarity for organizing scientific data, encouraging further observation and causal testing, and identifying policy entry points.

The effect of physical height on workplace success and income: preliminary test of a theoretical model.

PubMed

Judge, Timothy A; Cable, Daniel M

2004-06-01

In this article, the authors propose a theoretical model of the relationship between physical height and career success. We then test several linkages in the model based on a meta-analysis of the literature, with results indicating that physical height is significantly related to measures of social esteem (rho =.41), leader emergence (rho =.24), and performance (rho =.18). Height was somewhat more strongly related to success for men (rho =.29) than for women (rho =.21), although this difference was not significant. Finally, given that almost no research has examined the relationship between individuals' physical height and their incomes, we present four large-sample studies (total N = 8,590) showing that height is positively related to income (beta =.26) after controlling for sex, age, and weight. Overall, this article presents the most comprehensive analysis of the relationship of height to workplace success to date, and the results suggest that tall individuals have advantages in several important aspects of their careers and organizational lives.

Subgroup conflicts? Try the psychodramatic "double triad method".

PubMed

Verhofstadt-Denève, Leni M F

2012-04-01

The present article suggests the application of a psychodramatic action method for tackling subgroup conflicts in which the direct dialogue between representatives of two opposing subgroups is prepared step by step through an indirect dialogue strategy within two triads, a strategy known as the Double Triad Method (DTM). In order to achieve integration in the group as a whole, it is important that all the members of both subgroups participate actively during the entire process. The first part of the article briefly explores the theoretical background, with a special emphasis on the Phenomenological-Dialectical Personality Model (Phe-Di PModel). In the second part, the DTM procedure is systematically described through its five action stages, each accompanied with 1) a spatial representation of the consecutive actions, 2) some illustrative statements for each stage, and 3) a theoretical interpretation of the dialectically involved personality dimensions in both protagonists. The article concludes with a discussion and suggestions for more extensive applications of the DTM method, including the question of its relationships to Agazarian's functional subgrouping, psychodrama, and sociodrama.

A Theoretical Framework for a Virtual Diabetes Self-Management Community Intervention

PubMed Central

Vorderstrasse, Allison; Shaw, Ryan J.; Blascovich, Jim; Johnson, Constance M.

2015-01-01

Due to its high prevalence, chronic nature, potential complications, and self-management challenges for patients, diabetes presents significant health education and support issues. We developed and pilot-tested a virtual community for adults with type 2 diabetes to promote self-management education and provide social support. Although digital-based programs such as virtual environments can address significant barriers to reaching patients (i.e., child care, transportation, location), they must be strongly grounded in a theoretical basis to be well-developed and effective. In this article, we discuss how we synthesized behavioral and virtual environment theoretical frameworks to guide the development of SLIDES (Second Life Impacts Diabetes Education and Support).

Developing a theoretical framework for complex community-based interventions.

PubMed

Angeles, Ricardo N; Dolovich, Lisa; Kaczorowski, Janusz; Thabane, Lehana

2014-01-01

Applying existing theories to research, in the form of a theoretical framework, is necessary to advance knowledge from what is already known toward the next steps to be taken. This article proposes a guide on how to develop a theoretical framework for complex community-based interventions using the Cardiovascular Health Awareness Program as an example. Developing a theoretical framework starts with identifying the intervention's essential elements. Subsequent steps include the following: (a) identifying and defining the different variables (independent, dependent, mediating/intervening, moderating, and control); (b) postulating mechanisms how the independent variables will lead to the dependent variables; (c) identifying existing theoretical models supporting the theoretical framework under development; (d) scripting the theoretical framework into a figure or sets of statements as a series of hypotheses, if/then logic statements, or a visual model; (e) content and face validation of the theoretical framework; and (f) revising the theoretical framework. In our example, we combined the "diffusion of innovation theory" and the "health belief model" to develop our framework. Using the Cardiovascular Health Awareness Program as the model, we demonstrated a stepwise process of developing a theoretical framework. The challenges encountered are described, and an overview of the strategies employed to overcome these challenges is presented.

New robust statistical procedures for the polytomous logistic regression models.

PubMed

Castilla, Elena; Ghosh, Abhik; Martin, Nirian; Pardo, Leandro

2018-05-17

This article derives a new family of estimators, namely the minimum density power divergence estimators, as a robust generalization of the maximum likelihood estimator for the polytomous logistic regression model. Based on these estimators, a family of Wald-type test statistics for linear hypotheses is introduced. Robustness properties of both the proposed estimators and the test statistics are theoretically studied through the classical influence function analysis. Appropriate real life examples are presented to justify the requirement of suitable robust statistical procedures in place of the likelihood based inference for the polytomous logistic regression model. The validity of the theoretical results established in the article are further confirmed empirically through suitable simulation studies. Finally, an approach for the data-driven selection of the robustness tuning parameter is proposed with empirical justifications. © 2018, The International Biometric Society.

Health lifestyle theory and the convergence of agency and structure.

PubMed

Cockerham, William C

2005-03-01

This article utilizes the agency-structure debate as a framework for constructing a health lifestyle theory. No such theory currently exists, yet the need for one is underscored by the fact that many daily lifestyle practices involve considerations of health outcomes. An individualist paradigm has influenced concepts of health lifestyles in several disciplines, but this approach neglects the structural dimensions of such lifestyles and has limited applicability to the empirical world. The direction of this article is to present a theory of health lifestyles that includes considerations of both agency and structure, with an emphasis upon restoring structure to its appropriate position. The article begins by defining agency and structure, followed by presentation of a health lifestyle model and the theoretical and empirical studies that support it.

The Role of Trait Emotional Intelligence in Academic Performance: Theoretical Overview and Empirical Update.

PubMed

Perera, Harsha N

2016-01-01

Considerable debate still exists among scholars over the role of trait emotional intelligence (TEI) in academic performance. The dominant theoretical position is that TEI should be orthogonal or only weakly related to achievement; yet, there are strong theoretical reasons to believe that TEI plays a key role in performance. The purpose of the current article is to provide (a) an overview of the possible theoretical mechanisms linking TEI with achievement and (b) an update on empirical research examining this relationship. To elucidate these theoretical mechanisms, the overview draws on multiple theories of emotion and regulation, including TEI theory, social-functional accounts of emotion, and expectancy-value and psychobiological model of emotion and regulation. Although these theoretical accounts variously emphasize different variables as focal constructs, when taken together, they provide a comprehensive picture of the possible mechanisms linking TEI with achievement. In this regard, the article redresses the problem of vaguely specified theoretical links currently hampering progress in the field. The article closes with a consideration of directions for future research.

Physical-chemical processes of diamond grinding

NASA Astrophysics Data System (ADS)

Lobanov, D. V.; Arhipov, P. V.; Yanyushkin, A. S.; Skeeba, V. Yu

2017-10-01

The article focuses on the relevance of the research into the problem of diamond abrasive metal-bonded tool performance loss with a view to enhancing the effectiveness of high-strength materials finishing processing. The article presents the results of theoretical and empirical studies of loading layer formation on the surface of diamond wheels during processing high-strength materials. The theoretical part deals with the physical and chemical processes at the contact area of the diamond wheel and work surface with the viewpoint of the electrochemical potentials equilibrium state. We defined dependencies for calculating the loading layer dimensions. The practical part of work centers on various electron-microscopic, spectral and X-ray diffraction studies of the metal-bonded wheel samples during diamond grinding. The analysis of the research results revealed the composition and structure of the loading layer. The validity of the theoretical data is confirmed by sufficient convergence of the calculated values with the results of empirical research. In order to reduce the intensity of loading and improve the cutting properties of metal-bonded diamond abrasive tools, it is recommended to use combined methods for more efficient processing of high-strength materials.

Coping, acculturation, and psychological adaptation among migrants: a theoretical and empirical review and synthesis of the literature

PubMed Central

Kuo, Ben C.H.

2014-01-01

Given the continuous, dynamic demographic changes internationally due to intensive worldwide migration and globalization, the need to more fully understand how migrants adapt and cope with acculturation experiences in their new host cultural environment is imperative and timely. However, a comprehensive review of what we currently know about the relationship between coping behavior and acculturation experience for individuals undergoing cultural changes has not yet been undertaken. Hence, the current article aims to compile, review, and examine cumulative cross-cultural psychological research that sheds light on the relationships among coping, acculturation, and psychological and mental health outcomes for migrants. To this end, this present article reviews prevailing literature pertaining to: (a) the stress and coping conceptual perspective of acculturation; (b) four theoretical models of coping, acculturation and cultural adaptation; (c) differential coping pattern among diverse acculturating migrant groups; and (d) the relationship between coping variabilities and acculturation levels among migrants. In terms of theoretical understanding, this review points to the relative strengths and limitations associated with each of the four theoretical models on coping-acculturation-adaptation. These theories and the empirical studies reviewed in this article further highlight the central role of coping behaviors/strategies in the acculturation process and outcome for migrants and ethnic populations, both conceptually and functionally. Moreover, the review shows that across studies culturally preferred coping patterns exist among acculturating migrants and migrant groups and vary with migrants' acculturation levels. Implications and limitations of the existing literature for coping, acculturation, and psychological adaptation research are discussed and recommendations for future research are put forth.

The article concludes with a discussion of the advantages and implications of a holistic theoretical approach to ID.

Reviews of theoretical frameworks: Challenges and judging the quality of theory application.

PubMed

Hean, Sarah; Anderson, Liz; Green, Chris; John, Carol; Pitt, Richard; O'Halloran, Cath

2016-06-01

Rigorous reviews of available information, from a range of resources, are required to support medical and health educators in their decision making. The aim of this article is to highlight the importance of a review of theoretical frameworks specifically as a supplement to reviews that focus on a synthesis of the empirical evidence alone. Establishing a shared understanding of theory as a concept is highlighted as a challenge and some practical strategies to achieving this are presented. This article also introduces the concept of theoretical quality, arguing that a critique of how theory is applied should complement the methodological appraisal of the literature in a review. We illustrate the challenge of establishing a shared meaning of theory through reference to experiences of an on-going review of this kind conducted in the field of interprofessional education (IPE) and use a high scoring paper selected in this review to illustrate how theoretical quality can be assessed. In reaching a shared understanding of theory as a concept, practical strategies that promote experiential and practical ways of knowing are required in addition to more propositional ways of sharing knowledge. Concepts of parsimony, testability, operational adequacy and empirical adequacy are explored as concepts that establish theoretical quality. Reviews of theoretical frameworks used in medical education are required to inform educational practice. Review teams should make time and effort to reach a shared understanding of the term theory. Theory reviews, and reviews more widely, should add an assessment of theory application to the protocol of their review method.

BOOK REVIEW: Quantum Squeezing

NASA Astrophysics Data System (ADS)

Zubairy, Suhail

2005-05-01

Quantum squeezed states are a consequence of uncertainty relations; a state is squeezed when the noise in one variable is reduced below the symmetric limit at the expense of the increased noise in the conjugate variable such that the Heisenberg uncertainty relation is not violated. Such states have been known since the earliest days of quantum mechanics. The realization in the early 80's that quantum squeezed states of the radiation field can have important applications in high precision Michelson interferometry for detecting gravitational waves led to a tremendous amount of activity, both in theoretical and experimental quantum optics. The present volume, edited by two eminent scientists, is a collection of papers by leading experts in the field of squeezed states on different aspects of the field as it stands today. The book is divided into three parts. In the first part, there are three articles that review the fundamentals. The first paper by Knight and Buzek presents an introductory account of squeezed states and their properties. The chapter, which opens with the quantization of the radiation field, goes on to discuss the quantum optical properties of single mode and multimode squeezed states. The second article by Hillery provides a detailed description of field quantization in the presence of a nonlinear dielectric medium, thus providing a rigorous treatment of squeezing in nonlinear media. The third article by Yurke presents a comprehensive discussion of the input-output theory of the squeezed radiation at the dielectric boundaries. The second part of the book, comprising of three articles, deals with the generation of squeezed states. In the first article, Drummond reviews the squeezing properties of light in nonlinear systems such as parametric oscillators. He also discusses squeezed light propagation through waveguides and optical fibers. In the second article, Ralph concentrates on active laser sources of squeezing and presents an analysis based on the Langevin formalism for squeezing in lasing systems. In the last article of this part, Wiseman deals with squeezing systems when the system's environment can be deliberately engineered so that the feedback is important. The third part of the book includes four articles dealing with the applications of quantum squeezing. In the first article, Yuen presents a discussion of communications and measurement using squeezed states and discusses the advantages of using nonclassical light over classical light in communications and measurement. In the second article, Swain deals with the interaction of squeezed light with the atomic systems and presents a review of novel phenomena in spectroscopy. This chapter on two-level atomic system is followed by Ficek's article on squeezed-light based spectroscopy in three-level atomic systems. In the last article, Reid again addresses the advantages of squeezed light in communications, but her emphasis is different from that of Yuen's article. Here she discusses EPR correlations for squeezed light and presents squeezed-light based methods for quantum cryptography. All the authors are leading figures in the field of squeezed states who have made pioneering contributions to various aspects of the field over the years. This is reflected in the authoritative style with which all the articles are written. These articles are rich in content, easy to read and cover a broad base. The emphasis is however on the theoretical aspects with occasional references to experimental work. This book is an excellent collection of articles on quantum squeezing that are highly useful both for beginners who would like to learn about squeezing and its applications, as well as for experts who would like to learn about the frontiers.

Commonalities between Disaster and Climate Change Risks for Health: A Theoretical Framework.

PubMed

Banwell, Nicola; Rutherford, Shannon; Mackey, Brendan; Street, Roger; Chu, Cordia

2018-03-16

Disasters and climate change have significant implications for human health worldwide. Both climate change and the climate-sensitive hazards that result in disasters, are discussed in terms of direct and indirect impacts on health. A growing body of literature has argued for the need to link disaster risk reduction and climate change adaptation. However, there is limited articulation of the commonalities between these health impacts. Understanding the shared risk pathways is an important starting point for developing joint strategies for adapting to, and reducing, health risks. Therefore, this article discusses the common aspects of direct and indirect health risks of climate change and climate-sensitive disasters. Based on this discussion a theoretical framework is presented for understanding these commonalities. As such, this article hopes to extend the current health impact frameworks and provide a platform for further research exploring opportunities for linked adaptation and risk reduction strategies.

Framing new research in science literacy and language use: Authenticity, multiple discourses, and the Third Space

NASA Astrophysics Data System (ADS)

Wallace, Carolyn S.

2004-11-01

This article presents a theoretical framework in the form of a model on which to base research in scientific literacy and language use. The assumption guiding the framework is that scientific literacy is comprised of the abilities to think metacognitively, to read and write scientific texts, and to apply the elements of a scientific argument. The framework is composed of three theoretical constructs: authenticity, multiple discourses, and Bhabha's Third Space. Some of the implications of the framework are that students need opportunities to (a) use scientific language in everyday situations; (b) negotiate readily among the many discourse genres of science; and (c) collaborate with teachers and peers on the meaning of scientific language. These ideas are illustrated with data excerpts from contemporary research studies. A set of potential research issues for the future is posed at the end of the article.

Oral contraceptives and mood in women with and without premenstrual dysphoria: a theoretical model.

PubMed

Kurshan, N; Neill Epperson, C

2006-01-01

Despite numerous studies on the topic, there is no consensus to date on the effects of oral contraceptives on mood or the mechanism(s) by which they exert these effects. This review article presents a theoretical model to explain the way in which oral contraceptives may affect mood. Specifically, it is argued that progestins exert differential effects on endogenous levels of neurosteroids, thereby altering mood. After providing an overview of the effects of estrogen, progesterone, and progesterone's metabolites on cortical excitability and the role of neurosteroids in depression and premenstrual dysphoria, this article reviews the research that has been conducted on the relationship between oral contraceptives and neurosteroids. Finally, suggestions for future research are made with the dual aim of improving existing studies on the relationship between oral contraceptives and mood and further investigating the possibility that fluctuations in neurosteroid levels are responsible for the effects of oral contraceptives on mood.

A theoretical physicist's journey into biology: from quarks and strings to cells and whales.

PubMed

West, Geoffrey B

2014-10-08

Biology will almost certainly be the predominant science of the twenty-first century but, for it to become successfully so, it will need to embrace some of the quantitative, analytic, predictive culture that has made physics so successful. This includes the search for underlying principles, systemic thinking at all scales, the development of coarse-grained models, and closer ongoing collaboration between theorists and experimentalists. This article presents a personal, slightly provocative, perspective of a theoretical physicist working in close collaboration with biologists at the interface between the physical and biological sciences.

PubMed

Meng, Jingbo; Martinez, Lourdes; Holmstrom, Amanda; Chung, Minwoong; Cox, Jeff

2017-01-01

The article presents a narrative review of scholarship on social support through social networking sites (SNSs) published from 2004 to 2015. By searching keywords related to social support and SNSs in major databases for social sciences, we identified and content analyzed directly relevant articles (N = 88). The article summarizes the prevalence of theory usage; the function of theory usage (e.g., testing a theory, developing a theory); major theories referenced; and methodologies, including research designs, measurement, and the roles of social support and SNS examined in this literature. It also reports four themes identified across the studies, indicating the trends in the current research. Based on the review, the article presents a discussion about study sites, conceptualization of social support, theoretical coherence, the role of social networks, and the dynamic relationships between SNS use and social support, which points out potential avenues for shaping a future research agenda.

Clinical reasoning-embodied meaning-making in physiotherapy.

PubMed

Chowdhury, Anoop; Bjorbækmo, Wenche Schrøder

2017-07-01

This article examines physiotherapists' lived experience of practicing physiotherapy in primary care, focusing on clinical reasoning and decision-making in the case of a patient we call Eva. The material presented derives from a larger study involving two women participants, both with a protracted history of neck and shoulder pain. A total of eight sessions, all of them conducted by the first author, a professional physiotherapist, in his own practice room, were videotaped, after which the first author transcribed the sessions and added reflective notes. One session emerged as particularly stressful for both parties and is explored in detail in this article. In our analysis, we seek to be attentive to the experiences of physiotherapy displayed and to explore their meaning, significance and uniqueness from a phenomenological perspective. Our research reveals the complexity of integrating multiple theoretical perspectives of practice in clinical decision-making and suggests that a phenomenological perspective can provide insights into clinical encounters through its recognition of embodied knowledge. We argue that good physiotherapy practice demands tactfulness, sensitivity, and the desire to build a cooperative patient-therapist relationship. Informed by theoretical and practical knowledge from multiple disciplines, patient management can evolve and unfold beyond rehearsed routines and theoretical principles.

Human Rights and the Excess of Identity: A Legal and Theoretical Inquiry into the Notion of Identity in Strasbourg Case Law.

PubMed

Al Tamimi, Yussef

2018-06-01

Identity is a central theme in contemporary politics, but legal academia lacks a rigorous analysis of this concept. The aim of this article is twofold: (i) firstly, it aims to reveal presumptions on identity in human rights law by mapping how the European Court of Human Rights approaches identity and (ii) secondly, it seeks to analyse these presumptions using theoretical insights on identity. By merging legal and theoretical analysis, this article contributes a reading of the Court's case law which suggests that the tension between the political and apolitical is visible as a common thread in the Court's use of identity. In case law concerning paternity, the Court appears to hold a specific view of what is presented as an unquestionable part of identity. This ostensibly pre-political notion of identity becomes untenable in cases where the nature of an identity feature, such as the headscarf, is contended or a minority has adopted a national identity that conflicts with the majoritarian national identity. The Court's approach to identity in such cases reflects a paradox that is inherent to identity; identity is personal while simultaneously constituted and shaped by overarching power mechanisms.

When the “I” Looks at the “Me”: Autobiographical Memory, Visual Perspective, and the Self

PubMed Central

Sutin, Angelina R.; Robins, Richard W.

2009-01-01

This article presents a theoretical model of the self processes involved in autobiographical memories and proposes competing hypotheses for the role of visual perspective in autobiographical memory retrieval. Autobiographical memories can be retrieved from either the 1st person perspective, in which individuals see the event through their own eyes, or from the 3rd person perspective, in which individuals see themselves and the event from the perspective of an external observer. A growing body of research suggests that the visual perspective from which a memory is retrieved has important implications for a person's thoughts, feelings, and goals, and is integrally related to a host of self-evaluative processes. We review the relevant research literature, present our theoretical model, and outline directions for future research. PMID:18848783

Theoretical domains: a heuristic for teaching behavioral theory in HIV/STD prevention courses.

Dolcini, M Margaret; Canin, Lisa; Gandelman, Alice; Skolnik, Heidi

2004-10-01

The HIV/STD epidemics have broadened the need for better behavioral intervention programs and highlighted the importance of providing training in behavioral theory to frontline program practitioners. However, there is a lack of effective methods for teaching theoretical concepts to people who may not have a background in behavioral science. This article presents a solution to this challenge by introducing a new heuristic for teaching theory and for placing individual theories/models in a broader context. Using a broad framework, we identify five domains that influence behavior: risk appraisal, self-perceptions, emotions and arousal, relationships and social influence, and environmental and structural factors. Each domain is described, and a brief overview of supporting literature is provided. Following the presentation of domains, we discuss course structure and activities.

Supervisory process from a supportive-expressive relational psychodynamic approach.

Diener, Marc J; Mesrie, Vicky

2015-06-01

Substantial theoretical and empirical focus has been placed on detailing the processes that therapists use in psychotherapy. Relatively limited investigation, however, has been conducted into the utility of the various techniques and processes that supervisors use in facilitating the development of trainee competence to conduct psychotherapy. The present article explores 2 sets of supervisory techniques/processes that can be used to assist novice therapists in the development of clinical skills from a supportive-expressive (Luborsky, 1984) relational (Greenberg & Mitchell, 1983) psychodynamic approach: (a) providing systematic and structured training in interpretation, and (b) facilitating trainee use of countertransference. We detail the theoretical underpinnings and research findings for each supervisory process, followed by presentation of vignettes illustrating supervisor-supervisee interactions that demonstrate the use of these processes.

Bodies Matter: Professional Bodies and Embodiment in Institutional Sport Contexts

PubMed Central

van Amsterdam, Noortje; Claringbould, Inge; Knoppers, Annelies

2017-01-01

Bodies are always present in organizations, yet they frequently remain unacknowledged or invisible including in sport organizations and sport management research. We therefore argue for an embodied turn in sport management research. The purpose of this article is to present possible reasons why scholars have rarely paid attention to bodies in sport organizations; to offer arguments why they should do so; and to give suggestions for what scholarship on bodies and embodiment might look like using various theoretical frameworks. Using the topic of diversity as an example, we explore what insights into embodiment and bodily practices the theoretical frameworks of Foucault, Bourdieu, Merleau-Ponty and Butler have to offer researchers and how these insights may lead to better understandings of organizational processes in sport.

Counteracting moment device for reduction of earthquake-induced excursions of multi-level buildings.

PubMed

Nagaya, K; Fukushima, T; Kosugi, Y

1999-05-01

A vibration-control mechanism for beams and columns was presented in our previous report in which the earthquake force was transformed into a vibration-control force by using a gear train mechanism. In our previous report, however, only the principle of transforming the earthquake force into the control force was presented; the discussion for real structures and the design method were not presented. The present article provides a theoretical analysis of the column which is used in multi-layered buildings. Experimental tests were carried out for a model of multi-layered buildings in the frequency range of a principal earthquake wave. Theoretical results are compared to the experimental data. The optimal design of the control mechanism, which is of importance in the column design, is presented. Numerical calculations are carried out for the optimal design. It is shown that vibrations of the column involving the mechanism are suppressed remarkably. The optimal design method and the analytical results are applicable to the design of the column.

2017-01-01

This article aims to identify and critically assess qualitative intervention studies of rehabilitation processes that target young adults. By applying a meta-epistemological approach inspired by the works of Michel Foucault and Julia Kristeva, we examine how the included studies present qualitative knowledge and whether they adhere to their own stated principles of qualitative knowledge. Through their stated aims and theoretical framing, the articles draw attention to individual processes of meaning making. Nonetheless, we find that the articles to a great extent emphasize frequencies of the qualitative data they present. Individual processes and experiences are subject to subdivisions and categorization and transformed into manageable objects of knowledge. In conclusion, these studies, with one important exception, contribute to self-marginalization of the knowledge they themselves promote: They undermine the uniqueness of the qualitative knowledge they proclaim by focusing on frequency and the general patterns and categories encompassing the unique. © The Author(s) 2016.

The 2002 Sydney Gay Games: re-presenting "lesbian" identities through sporting space.

PubMed

Lambert, Karen

2009-01-01

In this article poetic representation in qualitative research is explored in relation to researching "lesbian" lives. Set within the context of The 2002 Sydney Gay Games the article considers how poetry can bring to light experiences at the intersection of sexuality, sport, and place. The article details three aspects to this process. First, by asking what queer theory could do for particular research subjects, a robust, malleable, and transportable theoretical concept of "queer" is proposed that is responsive to the participants' lives and experiences. Second, this concept is applied methodologically in order to unsettle more traditional academic modes of representing interview data through the use of poetic forms of representation. Finally, a poem constructed from the Opening Ceremony of The Gay Games is presented and analyzed. Poetic representation is thus offered as a distinct methodology that permits a particular kind of "queer" analysis when researching "lesbian" lives.

Sato, Priscila de Morais; Gittelsohn, Joel; Unsain, Ramiro Fernandez; Roble, Odilon José; Scagliusi, Fernanda Baeza

2016-01-01

This article reviews and discusses scientific papers on eating practices that have used Pierre Bourdieu's concepts presented in Distinction: A Social Critique of the Judgement of Taste. It aims to synthesize and analyze theoretical and empirical studies on the theme in order to present Bourdieu's contributions to the field, advances in his theories, and directions for future research. Exclusion criteria were: not written in Portuguese, English, Spanish, or French; not published in a peer-reviewed journal; not analyzing food or eating; and not using Bourdieu's concepts as presented in Distinction as the main theoretical framework. In this narrative review, we found 38 articles, which were categorized main themes: food choice and provisioning, taste, social class, food symbolism, the body, and the scientific field of food and eating. The taste of luxury and the taste of necessity were broadly applied on the works found in this review and were observed among the lower and upper classes, manifesting differently in each class. These studies show that while Bourdieu's theories are still highly relevant to understanding contemporary social groups, they may be improved when combined with other frameworks and theorists. We highlight as directions for future research manners in which gender and the environment interact with the habitus and food choices. Finally, this review points to new areas of investigation that may help improve the use of Bourdieu's concepts in exploring health inequalities, such as differences in eating practices and habitus within populations with low socioeconomic status.

McDowell, M. W.; Bouwer, H. K.

In a recent article, several configurations were described whereby a Rowland mount spectrometer could be modified to cover a wavelength range of 120-950 nm. In one of these configurations, large additional image aberration is introduced which severely limits the spectral resolving power. In the present article, the theoretical imaging properties of this configuration are considered and a simple method is proposed to reduce this aberration. The optimized system possesses an image quality similar to the conventional Rowland mount with the image surface slightly displaced from the Rowland circle but concentric to it.

Factors to consider when reviewing and reconciling research findings: Methodological, statistical and theoretical.

PubMed

Robinson, Sally J

2017-11-07

Neuroscience is a rapidly evolving interdisciplinary field that is changing the way research is conducted and theories are developed. However, variability between studies and apparently discrepant findings may contribute to difficulties identifying commonalities that can help inform and enhance clinical practice. This article presents a framework to consider when reviewing neuropsychological studies, such that apparent discrepancies in findings may be considered in unison to provide informed theoretical understanding. For illustrative purposes, the article considers the studies of Vargha-Khadem, Salmond, Friston, Gadian, and Mishkin ( 2003 ) and Beauchamp et al. ( 2008 ), which report contrasting memory deficits during development in association with apparently similar bilateral hippocampal damage. The importance of reflecting on participant characteristics, methodological approaches, statistical analysis, and the interpretative value placed on selective test findings are discussed. Factors such as functional brain development, relationships between apparently "typical" functioning and underlying neural structures and networks, the limits of plasticity on the developing cognitive system and clinical implications are also considered. Thus, this article provides a structure that can be applied when reviewing neuropsychological studies and evaluating research inconsistencies, with consideration of the need for greater collaboration between neuroscientists and clinicians to support the development of translational research with real life implications.

MHD-waves in the geomagnetic tail: A review

NASA Astrophysics Data System (ADS)

Leonovich, Anatoliy; Mazur, Vitaliy; Kozlov, Daniil

2015-03-01

This article presents the review of experimental and theoretical studies on ultra-lowfrequency MHD oscillations of the geomagnetic tail. We consider the Kelvin-Helmholtz instability at the magnetopause, oscillations with a discrete spectrum in the "magic frequencies"range, the ballooning instability of coupled Alfvén and slow magnetosonic waves, and "flapping" oscillations of the current sheet of the geomagnetic tail. Over the last decade, observations from THEMIS, CLUSTER and Double Star satellites have been of great importance for experimental studies. The use of several spacecraft allows us to study the structure of MHD oscillations with high spatial resolution. Due to this, we can make a detailed comparison between theoretical results and those obtained from multi-spacecraft studies. To make such comparisons in theoretical studies, in turn, we have to use the numerical models closest to the real magnetosphere.

Beyond the hypothesis: Theory's role in the genesis, opposition, and pursuit of the Higgs boson

NASA Astrophysics Data System (ADS)

Wells, James D.

2018-05-01

The centrally recognized theoretical achievement that enabled the Higgs boson discovery in 2012 was the hypothesis of its existence, made by Peter Higgs in 1964. Nevertheless, there is a significant body of comparably important theoretical work prior to and after the Higgs boson hypothesis. In this article we present an additional perspective of how crucial theory work was to the genesis of the Higgs boson hypothesis, especially emphasizing its roots in Landau's theory of phase transitions and subsequent theoretical work on superconductivity. A detailed description is then given of the opposition to the Higgs boson hypothesis by many researchers, giving evidence to its speculative nature. And finally, it is discussed the importance of theory work in the decades after the hypothesis in order to make possible the experimental discovery of the Higgs boson.

Generalized Constitutive-Based Theoretical and Empirical Models for Hot Working Behavior of Functionally Graded Steels

Vanini, Seyed Ali Sadough; Abolghasemzadeh, Mohammad; Assadi, Abbas

2013-07-01

Functionally graded steels with graded ferritic and austenitic regions including bainite and martensite intermediate layers produced by electroslag remelting have attracted much attention in recent years. In this article, an empirical model based on the Zener-Hollomon (Z-H) constitutive equation with generalized material constants is presented to investigate the effects of temperature and strain rate on the hot working behavior of functionally graded steels. Next, a theoretical model, generalized by strain compensation, is developed for the flow stress estimation of functionally graded steels under hot compression based on the phase mixture rule and boundary layer characteristics. The model is used for different strains and grading configurations. Specifically, the results for αβγMγ steels from empirical and theoretical models showed excellent agreement with those of experiments of other references within acceptable error.

A clinical treatment intervention for dysphoria: externalizing metaphors therapy.

PubMed

McGuinty, Everett; Armstrong, David; Carrière, Anne-Marie

2014-01-01

The purpose of this article is to explore a novel, short-term treatment intervention for internalizing behaviours. This intervention is primarily based upon an externalizing process, transforming of metaphoric imagery, and shifting of underlying maladaptive emotional schemas. This article addresses the clinical population of children and youth, specifically through outlining the protocol, externalizing metaphors therapy. A selective review of significant works regarding the efficacy of short-term therapy was conducted, including the process of change within narrative therapy. It is proposed that two specific processes account for the mental health change experienced by clients who receive this new treatment intervention: (1) externalization of problems and (2) purposeful client-generated metaphor manipulation, impacting upon underlying schemas. From these theoretical constructs, the present article outlines a three-session treatment protocol that manualizes these key clinical processes. A case study is presented to illustrate this intervention for anxiety and depression. Further clinical research is underway to address the testable hypotheses resulting from the current theoretical model. Clinical trials in brief psychotherapy are suggested to empirically evaluate the efficacy of this new treatment intervention for dysphoria. This article outlines a short-term treatment intervention for anxiety and depression (dysphoira) through a novel 3-session model, where the clinician-practitioner can obtain competency through a one-day workshop.Its relevance for the clinical researcher and the mental health community is in its versatility in addressing internalizing behavior for four clinical populations: (1) children and adolescents; (2) children and adolescents on the autism spectrum; (3) adults in general; and, (4) adults with a dual-diagnosis. The treatment protocol described within is based upon the externalizing and deconstructive properties of Narrative Therapy, and the transformation of metaphoric imagery of Metaphor Therapy; both of which have little empirical support with narrative practices gaining international attention and widespread usage - through brief therapy, long-term therapy, and walk-in clinics in North America. For the first time, the theoretical constructs of the 3-session model are described and a case example illustrates the interlinking concepts. Copyright © 2013 John Wiley & Sons, Ltd.

[Phenomenological anthropological social psychiatry--paving the way for a theoretical reanimation].

PubMed

Thoma, Samuel

2012-11-01

This article tries to link the present lack of theoretical discussion within German Social Psychiatry with a loss of phenomenological and anthropological thought. The so-called Phenomenological Psychiatry used to play a very important role in German psychiatry during the 50 ies until the 70 ies and had strong influences on the first reformers of German psychiatry, such as Walter Ritter von Baeyer, Heinz Häfner, Caspar Kulenkampff, Karl Peter Kisker and Erich Wulff. Their reforms were not only founded by a social criticism put forth by theories such as marxism (Basaglia, Wulff) or structuralism (Foucault) but also by a concrete notion of what it is like to suffer from mental illness and what kind of needs are linked to such suffering. This very notion was given by the phenomenological approach. Finally the article tries to give reasons for today's reciprocal loss of connection of the phenomenological and the socio-psychiatric school. © Georg Thieme Verlag KG Stuttgart · New York.

Argumentation in Science Education: A Model-based Framework

NASA Astrophysics Data System (ADS)

Böttcher, Florian; Meisert, Anke

2011-02-01

The goal of this article is threefold: First, the theoretical background for a model-based framework of argumentation to describe and evaluate argumentative processes in science education is presented. Based on the general model-based perspective in cognitive science and the philosophy of science, it is proposed to understand arguments as reasons for the appropriateness of a theoretical model which explains a certain phenomenon. Argumentation is considered to be the process of the critical evaluation of such a model if necessary in relation to alternative models. Secondly, some methodological details are exemplified for the use of a model-based analysis in the concrete classroom context. Third, the application of the approach in comparison with other analytical models will be presented to demonstrate the explicatory power and depth of the model-based perspective. Primarily, the framework of Toulmin to structurally analyse arguments is contrasted with the approach presented here. It will be demonstrated how common methodological and theoretical problems in the context of Toulmin's framework can be overcome through a model-based perspective. Additionally, a second more complex argumentative sequence will also be analysed according to the invented analytical scheme to give a broader impression of its potential in practical use.

Two-agent cooperative search using game models with endurance-time constraints

NASA Astrophysics Data System (ADS)

Sujit, P. B.; Ghose, Debasish

2010-07-01

In this article, the problem of two Unmanned Aerial Vehicles (UAVs) cooperatively searching an unknown region is addressed. The search region is discretized into hexagonal cells and each cell is assumed to possess an uncertainty value. The UAVs have to cooperatively search these cells taking limited endurance, sensor and communication range constraints into account. Due to limited endurance, the UAVs need to return to the base station for refuelling and also need to select a base station when multiple base stations are present. This article proposes a route planning algorithm that takes endurance time constraints into account and uses game theoretical strategies to reduce the uncertainty. The route planning algorithm selects only those cells that ensure the agent will return to any one of the available bases. A set of paths are formed using these cells which the game theoretical strategies use to select a path that yields maximum uncertainty reduction. We explore non-cooperative Nash, cooperative and security strategies from game theory to enhance the search effectiveness. Monte-Carlo simulations are carried out which show the superiority of the game theoretical strategies over greedy strategy for different look ahead step length paths. Within the game theoretical strategies, non-cooperative Nash and cooperative strategy perform similarly in an ideal case, but Nash strategy performs better than the cooperative strategy when the perceived information is different. We also propose a heuristic based on partitioning of the search space into sectors to reduce computational overhead without performance degradation.

A Diagnostic Marker to Discriminate Childhood Apraxia of Speech From Speech Delay: III. Theoretical Coherence of the Pause Marker with Speech Processing Deficits in Childhood Apraxia of Speech.

PubMed

Shriberg, Lawrence D; Strand, Edythe A; Fourakis, Marios; Jakielski, Kathy J; Hall, Sheryl D; Karlsson, Heather B; Mabie, Heather L; McSweeny, Jane L; Tilkens, Christie M; Wilson, David L

2017-04-14

Previous articles in this supplement described rationale for and development of the pause marker (PM), a diagnostic marker of childhood apraxia of speech (CAS), and studies supporting its validity and reliability. The present article assesses the theoretical coherence of the PM with speech processing deficits in CAS. PM and other scores were obtained for 264 participants in 6 groups: CAS in idiopathic, neurogenetic, and complex neurodevelopmental disorders; adult-onset apraxia of speech (AAS) consequent to stroke and primary progressive apraxia of speech; and idiopathic speech delay. Participants with CAS and AAS had significantly lower scores than typically speaking reference participants and speech delay controls on measures posited to assess representational and transcoding processes. Representational deficits differed between CAS and AAS groups, with support for both underspecified linguistic representations and memory/access deficits in CAS, but for only the latter in AAS. CAS-AAS similarities in the age-sex standardized percentages of occurrence of the most frequent type of inappropriate pauses (abrupt) and significant differences in the standardized occurrence of appropriate pauses were consistent with speech processing findings. Results support the hypotheses of core representational and transcoding speech processing deficits in CAS and theoretical coherence of the PM's pause-speech elements with these deficits.

Trajectories on the path to reciprocity-A theoretical framework for collaborating with socioeconomically disadvantaged communities.

PubMed

Minas, Maria; Ribeiro, Maria Teresa; Anglin, James P

2018-01-01

The importance of cultivating connection to enhance individual, relational and collective well-being is gaining attention in the current literature on building community. Although these goals are being increasingly considered, the concept of reciprocity has been less prominent than may be warranted in the field of psychology. This article presents a theoretical framework on the dynamics of reciprocity which resulted from grounded theory (GT) research involving 2 complementary studies. The first study involved 22 participants from different socioeconomic backgrounds engaged in "reflecting-team with appreciative audiences" sessions (Madsen, 2007) in Portugal. The second study involved participant observation of 15 community programs recognized as good-practices in collaboration with socioeconomically disadvantaged participants, at national and international levels, across 9 countries. The theoretical framework emphasizes the centrality of building reciprocity for the development of individuals, families, communities, and programs. It integrates the trajectories of reciprocity; quadrants reflecting the standpoints assumed according to socioeconomic and cultural positions; basic social-psychological processes inherent to the process of building reciprocity; and characterizes different types of programs. The resulting framework is analyzed in relation to prior literature for a broader understanding of synergies and challenges, and the article concludes by suggesting implications for further research and practice.

From atomistic interfaces to dendritic patterns

NASA Astrophysics Data System (ADS)

Galenko, P. K.; Alexandrov, D. V.

2018-01-01

Transport processes around phase interfaces, together with thermodynamic properties and kinetic phenomena, control the formation of dendritic patterns. Using the thermodynamic and kinetic data of phase interfaces obtained on the atomic scale, one can analyse the formation of a single dendrite and the growth of a dendritic ensemble. This is the result of recent progress in theoretical methods and computational algorithms calculated using powerful computer clusters. Great benefits can be attained from the development of micro-, meso- and macro-levels of analysis when investigating the dynamics of interfaces, interpreting experimental data and designing the macrostructure of samples. The review and research articles in this theme issue cover the spectrum of scales (from nano- to macro-length scales) in order to exhibit recently developing trends in the theoretical analysis and computational modelling of dendrite pattern formation. Atomistic modelling, the flow effect on interface dynamics, the transition from diffusion-limited to thermally controlled growth existing at a considerable driving force, two-phase (mushy) layer formation, the growth of eutectic dendrites, the formation of a secondary dendritic network due to coalescence, computational methods, including boundary integral and phase-field methods, and experimental tests for theoretical models-all these themes are highlighted in the present issue. This article is part of the theme issue `From atomistic interfaces to dendritic patterns'.

Heavy use of equations impedes communication among biologists.

PubMed

Fawcett, Tim W; Higginson, Andrew D

2012-07-17

Most research in biology is empirical, yet empirical studies rely fundamentally on theoretical work for generating testable predictions and interpreting observations. Despite this interdependence, many empirical studies build largely on other empirical studies with little direct reference to relevant theory, suggesting a failure of communication that may hinder scientific progress. To investigate the extent of this problem, we analyzed how the use of mathematical equations affects the scientific impact of studies in ecology and evolution. The density of equations in an article has a significant negative impact on citation rates, with papers receiving 28% fewer citations overall for each additional equation per page in the main text. Long, equation-dense papers tend to be more frequently cited by other theoretical papers, but this increase is outweighed by a sharp drop in citations from nontheoretical papers (35% fewer citations for each additional equation per page in the main text). In contrast, equations presented in an accompanying appendix do not lessen a paper's impact. Our analysis suggests possible strategies for enhancing the presentation of mathematical models to facilitate progress in disciplines that rely on the tight integration of theoretical and empirical work.

Creating creativity: reflections from fieldwork.

PubMed

Glăveanu, Vlad Petre

2011-03-01

The present article addresses the question of 'When can we say something is creative?' and, in answering it, takes a critical stand towards past and present scientific definitions of creativity. It challenges an implicit assumption in much psychological theory and research that creativity exists as an 'objective' feature of persons or products, universally recognised and independent of social agreement and cultural systems of norms and beliefs. Focusing on everyday life creative outcomes, the article includes both theoretical accounts and empirical examples from a research exploring creativity evaluations in the context of folk art. In the end, a multi-layered perspective of creativity assessment emerges, integrating dimensions such as newness and originality, value and usefulness, subjective reception and cultural reception of creative products. Implications for how we understand and study creativity are discussed.

This two-part article explores the process of role transition as it pertains to nurses moving from roles of caregivers to roles of case managers. Part 1 of the article presented a theoretical model that demonstrated the interplay of significant factors in the process of role transition and discussed how this model could be used to examine nurses' experience of this transition. Part 2 presents findings from a qualitative study involving interview and focus group data contributed by nurses who have made the transition from caregiver to case manager. Data point to specific tensions experienced by these nurses, which are associated with time-task orientation, interactions and relationships, business culture and objectives, and self-image and professional identity. Recommendations for preparing and supporting nurses through this role are also offered.

An Integrative Perspective on Interpersonal Coordination in Interactive Team Sports

PubMed Central

Steiner, Silvan; Macquet, Anne-Claire; Seiler, Roland

2017-01-01

Interpersonal coordination is a key factor in team performance. In interactive team sports, the limited predictability of a constantly changing context makes coordination challenging. Approaches that highlight the support provided by environmental information and theories of shared mental models provide potential explanations of how interpersonal coordination can nonetheless be established. In this article, we first outline the main assumptions of these approaches and consider criticisms that have been raised with regard to each. The aim of this article is to define a theoretical perspective that integrates the coordination mechanisms of the two approaches. In doing so, we borrow from a theoretical outline of group action. According to this outline, group action based on a priori shared mental models is an example of how interpersonal coordination is established from the top down. Interpersonal coordination in reaction to the perception of affordances represents the bottom-up component of group action. Both components are inextricably involved in the coordination of interactive sports teams. We further elaborate on the theoretical outline to integrate a third, constructivist approach. Integrating this third approach helps to explain interpersonal coordination in game situations for which no shared mental models are established and game situations that remain ambiguous in terms of perceived affordances. The article describes how hierarchical, sequential, and complex dimensions of action organization are important aspects of this constructivist perspective and how mental models may be involved. A basketball example is used to illustrate how top-down, bottom-up and constructivist processes may be simultaneously involved in enabling interpersonal coordination. Finally, we present the implications for research and practice. PMID:28894428

Mediating objects: scientific and public functions of models in nineteenth-century biology.

PubMed

Ludwig, David

2013-01-01

The aim of this article is to examine the scientific and public functions of two- and three-dimensional models in the context of three episodes from nineteenth-century biology. I argue that these models incorporate both data and theory by presenting theoretical assumptions in the light of concrete data or organizing data through theoretical assumptions. Despite their diverse roles in scientific practice, they all can be characterized as mediators between data and theory. Furthermore, I argue that these different mediating functions often reflect their different audiences that included specialized scientists, students, and the general public. In this sense, models in nineteenth-century biology can be understood as mediators between theory, data, and their diverse audiences.

The effects of structural differences in CADs on their spectroscopic properties were studied in detail by both: solid-state NMR and GIAO/GIPAW calculations. Theoretical computations were used in order to perform signal assignment in 13C CP/MAS NMR spectra of the cinnamic, o-coumaric, m-coumaric, p-coumaric, caffeic, ferulic, sinapic and 3,4-dimethoxycinnamic acids, and to evaluate the accuracy of GIPAW and GIAO methodology.

Ludwig von Bertalanffy's organismic view on the theory of evolution.

PubMed

Drack, Manfred

2015-03-01

Ludwig von Bertalanffy was a key figure in the advancement of theoretical biology. His early considerations already led him to recognize the necessity of considering the organism as a system, as an organization of parts and processes. He termed the resulting research program organismic biology, which he extended to all basic questions of biology and almost all areas of biology, hence also to the theory of evolution. This article begins by outlining the rather unknown (because often written in German) research of Bertalanffy in the field of theoretical biology. The basics of the organismic approach are then described. This is followed by Bertalanffy's considerations on the theory of evolution, in which he used methods from theoretical biology and then introduced his own, organismic, view on evolution, leading to the demand for finding laws of evolution. Finally, his view on the concept of homology is presented. © 2015 Wiley Periodicals, Inc.

Structural studies of homoisoflavonoids: NMR spectroscopy, X-ray diffraction, and theoretical calculations

In this article we present a detailed structural investigation for five homoisoflavonoids, molecules important from the pharmacological point of view. For studying the electron distribution as well as its influence on the physicochemical properties, NMR spectroscopy, X-ray diffraction, and theoretical calculations have been used. Nuclear magnetic shieldings obtained by using DFT calculations for optimized molecular geometries are correlated with the experimentally determined chemical shifts. The theoretical data are well in agreement with the experimental values. The single crystal X-ray structures of homoisoflavonoid derivatives 1, 3, and 4 have been solved. The molecular geometries and crystal packing determined by X-ray diffraction are used for characterizing the intermolecular interactions. Electron distribution is crucial for the stability of radicals and hence the antioxidant efficiency of flavonoid structures. The hydrogen bonding governs the formation of complexes of homoisoflavonoids with biological targets.

2014-04-01

Theoretical analysis for an online measurement of the stack gas flow velocity based on the optical scintillation method with a structure of two parallel optical paths is performed. The causes of optical scintillation in a stack are first introduced. Then, the principle of flow velocity measurement and its mathematical expression based on cross correlation of the optical scintillation are presented. The field test results show that the flow velocity measured by the proposed technique in this article is consistent with the value tested by the Pitot tube. It verifies the effectiveness of this method. Finally, by use of the structure function of logarithmic light intensity fluctuations, the theoretical explanation of optical scintillation spectral characteristic in low frequency is given. The analysis of the optical scintillation spectrum provides the basis for the measurement of the stack gas flow velocity and particle concentration simultaneously.

Application of the Consumer Decision-Making Model to Hearing Aid Adoption in First-Time Users

PubMed Central

Amlani, Amyn M.

2016-01-01

Since 1980, hearing aid adoption rates have remained essentially the same, increasing at a rate equal to the organic growth of the population. Researchers have used theoretical models from psychology and sociology to determine those factors or constructs that lead to the adoption of hearing aids by first-time impaired listeners entering the market. In this article, a theoretical model, the Consumer Decision-Making Model (CDM), premised on the neobehavioral approach that considers an individual's psychological and cognitive emphasis toward a product or service, is described. Three theoretical models (i.e., transtheoretical, social model of disability, Health Belief Model), and their relevant findings to the hearing aid market, are initially described. The CDM is then presented, along with supporting evidence of the model's various factors from the hearing aid literature. Future applications of the CDM to hearing health care also are discussed.

This article examines the doctrine of cultural relativism in nursing practice. To introduce the issue, an overview of the intellectual history of cultural relativism is presented. The academic themes of the debate surrounding cultural relativism are illustrated with an example of the social controversy in France involving cultural relativism as used to defend the practice of female genital excision among immigrant communities. The dilemma faced by nursing in making cross-cultural judgments is then examined in the light of the academic and social debates. The article concludes with a theoretical resolution of the issue of cultural relativism for nursing practice that is based on hermeneutic philosophy.

Antimatter and 20th century science

NASA Astrophysics Data System (ADS)

Williams, Gary

2005-03-01

This article gives an outline of the history of antimatter from the concept first introduced in 1898 up to the present day and is intended to complement the article 'Antihydrogen on Tap’ on page 229. It is hoped that it will provide enough historical background material along with interesting snippets of information for teachers to feel informed about the topic when in the classroom. Antimatter is the perfect example of 20th century science incorporating quantum mechanics and relativity, and showing progression from a theoretical idea to mass production within the space of 100 years. The final section is about using the idea of antihydrogen in the classroom.

Nordmann, J.; Aßmus, M.; Altenbach, H.

2018-02-01

In this article, we present the technical realisation for visualisations of characteristic parameters of the fourth-order elasticity tensor, which is classified by three-dimensional symmetry groups. Hereby, expressions for spatial representations of uc(Young)'s modulus and bulk modulus as well as plane representations of shear modulus and uc(Poisson)'s ratio are derived and transferred into a comprehensible form to computer algebra systems. Additionally, we present approaches for spatial representations of both latter parameters. These three- and two-dimensional representations are implemented into the software MATrix LABoratory. Exemplary representations of characteristic materials complete the present treatise.

The Competencies Conference: Future Directions in Education and Credentialing in Professional Psychology was held in Arizona in November 2002. One of the workshops, Individual and Cultural Differences (ICD), focused on racism, homophobia, and ageism. The consensus was that self-awareness and knowledge about the three "isms" are critical components in the education and training of psychologists. This article, authored by four of the workshop attendees, is a review of the current research and theoretical literature. Implications that address both content and context in graduate programs and training sites are presented. This is one of a series of articles published in this issue of the Journal of Clinical Psychology. Several other articles that resulted from the Competencies Conference will appear in Professional Psychology: Research and Practice and The Counseling Psychologist.

Excess success for three related papers on racial bias.

PubMed

Francis, Gregory

2015-01-01

Three related articles reported that racial bias altered perceptual experience and influenced decision-making. These findings have been applied to training programs for law enforcement, and elsewhere, to mitigate racial bias. However, a statistical analysis of each of the three articles finds that the reported experimental results should be rare, even if the theoretical ideas were correct. The analysis estimates that the probability of the reported experimental success for the articles is 0.003, 0.048, and 0.070, respectively. These low probabilities suggest that similar future work is unlikely to produce as successful outcomes and indicates that readers should be skeptical about the validity of the reported findings and their theoretical implications. The reported findings should not be used to guide policies related to racial bias, and new experimental work is needed to judge the merit of the theoretical ideas.

This article presents a review of our present understanding of the spin structure of the unpolarized hadron. Particular attention is paid to the quark sector at leading twist, namely, the quark Boer-Mulders function, which describes the transverse polarization of the quark inside an unpolarized hadron. After introducing the operator definition of the Boer-Mulders function, a detailed treatment of different non-perturbative calculations of the Boer-Mulders functions is provided. The phenomenology in Drell-Yan processes and semi-inclusive leptoproduction, including the extraction of the quark and antiquark Boer-Mulders functions from experimental data, is presented comprehensively. Finally, prospects for future theoretical studies and experimental measurements are presented in brief.

Blade resonance parameter identification based on tip-timing method without the once-per revolution sensor

NASA Astrophysics Data System (ADS)

Guo, Haotian; Duan, Fajie; Zhang, Jilong

2016-01-01

Blade tip-timing is the most effective method for blade vibration online measurement of turbomachinery. In this article a synchronous resonance vibration measurement method of blade based on tip-timing is presented. This method requires no once-per revolution sensor which makes it more generally applicable in the condition where this sensor is difficult to install, especially for the high-pressure rotors of dual-rotor engines. Only three casing mounted probes are required to identify the engine order, amplitude, natural frequency and the damping coefficient of the blade. A method is developed to identify the blade which a tip-timing data belongs to without once-per revolution sensor. Theoretical analyses of resonance parameter measurement are presented. Theoretic error of the method is investigated and corrected. Experiments are conducted and the results indicate that blade resonance parameter identification is achieved without once-per revolution sensor.

A Chinese view of the Western nursing metaparadigm.

Kao, Hsueh-Fen Sabrina; Reeder, Francelyn M; Hsu, Min-Tao; Cheng, Su-Fen

2006-06-01

The purpose of this article is to reveal Chinese-rooted meanings present within the Western nursing metaparadigm and to illustrate some similarities with Rogers's Science of Unitary Human Beings. Confucian and Taoist beliefs have the potential to illuminate the basic constructs inherent in holistic nursing. The Western nursing metaparadigm of four concepts--person, nursing, health, and environment--was explored through the lens of a Chinese worldview and led to the presentation of a broadened view for an integrated model of nursing. Asian and Western worldviews of human beings and health are not mutually exclusive. The Chinese holistic worldview of Taoism and Confucianism resonates theoretically and cosmically with the dynamic nature of the human-environment mutual relationship basic to Rogers' unitary view. This strong, theoretical link, when elaborated for its similarities and implications, can broaden the knowledge base to guide contemporary nursing practice, education, and research, particularly relevant for holistic nursing.

Mobile Devices: A Distraction, or a Useful Tool to Engage Nursing Students?

Gallegos, Cara; Nakashima, Hannah

2018-03-01

Engaging nursing students in theoretical courses, such as research, can be challenging. Innovative instructional strategies are essential to engage nursing students in theoretical nursing courses. This article describes an educational innovation using technology as a tool in an undergraduate nursing research class. All students in the course received iPads for the semester. Lecture material was presented in class using Nearpod, an interactive presentation embedded with slides, multimedia components, and learning activities. Students reported that using the mobile technology helped them minimize off-task activities, interact more with each other and the instructor, solve problems in the class, and develop skills and confidence related to their career. Allowing device use in the classroom, such as iPads and interactive mobile applications, can be a useful learning tool. Intentional use of technology and pedagogy can increase engagement and interaction with students. [J Nurs Educ. 2018;57(3):170-173.]. Copyright 2018, SLACK Incorporated.

Treatment technique training needs theoretical and practical knowledge allowing proposing the right treatment for the right patient, but also allowing performing the technical gesture in the best conditions for an optimal result with a maximal security. The evolution of the brachytherapy techniques needs the set up of specific theoretical and practical training sessions. The present article focuses on the importance of the brachytherapy training as well as the different means currently available for the young radiation oncologist community for perfecting their education. National and international trainings are presented. The role of the simulation principle in the frame of brachytherapy is also discussed. Even if brachytherapy is not always an easy technique, its efficacy and its medico-economical impact need to be passed down to motivated students with the implementation of relevant educational means.

On the societal nature of praxis and organic research

Roth, Wolff-Michael

2016-03-01

In its focus on social practices, the feature article presents an interesting theoretical framework for rethinking not only where and how knowing and learning in science education exhibit themselves but also we might change our own research practice. The framework is not new to me, as I have advocated it explicitly for more than 15 years. But over time it became apparent to me that some particularities of participation in practice may be grounded more strongly in an orientation towards the societal nature of any human praxis. In this forum contribution, I present a theoretical approach built on societal-historical activity theory that also takes activism as a major category for theorizing participation. This approach not only covers the extent of the social practice framework but also allows us to make thematic the production of inequity and restrictions to access science and engineering that are characteristic of many societies.

The studies selected using the methodology indicate research in ergonomics focused on the production of milk in rural areas, specifically in the milking sector, are generally related to the health and safety of the workers.

A theoretical and empirical review of the death-thought accessibility concept in terror management research.

PubMed

Hayes, Joseph; Schimel, Jeff; Arndt, Jamie; Faucher, Erik H

2010-09-01

Terror management theory (TMT) highlights the motivational impact of thoughts of death in various aspects of everyday life. Since its inception in 1986, research on TMT has undergone a slight but significant shift from an almost exclusive focus on the manipulation of thoughts of death to a marked increase in studies that measure the accessibility of death-related cognition. Indeed, the number of death-thought accessibility (DTA) studies in the published literature has grown substantially in recent years. In light of this increasing reliance on the DTA concept, the present article is meant to provide a comprehensive theoretical and empirical review of the literature employing this concept. After discussing the roots of DTA, the authors outline the theoretical refinements to TMT that have accompanied significant research findings associated with the DTA concept. Four distinct categories (mortality salience, death association, anxiety-buffer threat, and dispositional) are derived to organize the reviewed DTA studies, and the theoretical implications of each category are discussed. Finally, a number of lingering empirical and theoretical issues in the DTA literature are discussed with the aim of stimulating and focusing future research on DTA specifically and TMT in general.

Analysis of whisker-toughened CMC structural components using an interactive reliability model

1992-01-01

Realizing wider utilization of ceramic matrix composites (CMC) requires the development of advanced structural analysis technologies. This article focuses on the use of interactive reliability models to predict component probability of failure. The deterministic William-Warnke failure criterion serves as theoretical basis for the reliability model presented here. The model has been implemented into a test-bed software program. This computer program has been coupled to a general-purpose finite element program. A simple structural problem is presented to illustrate the reliability model and the computer algorithm.

This article focuses on social representations of alternative medicines by a group of professors from the School of Medicine and health professionals from the public health system in the city of Campinas, São Paulo, basically physicians and nurses. The article also emphasizes personal trajectories by which these health professionals opted for a dissident theoretical and practical perspective vis-à-vis the hegemonic positivist scientific medical paradigm. The research methods were mainly ethnographic, from a phenomenological perspective. The article concludes by sustaining (in theoretical terms) the importance of these dissident perspectives for scientific development.

Health care simulation is a powerful educational tool to help facilitate learning for clinicians and change their practice to improve patient outcomes and safety. To promote effective life-long learning through simulation, the educator needs to consider individuals, their experiences, and their environments. Effective education of adults through simulation requires a sound understanding of both adult learning theory and experiential learning. This review article provides a framework for developing and facilitating simulation courses, founded upon empiric and theoretic research in adult and experiential learning. Specifically, this article provides a theoretic foundation for using simulation to change practice to improve patient outcomes and safety. Copyright © 2011 Elsevier Inc. All rights reserved.

Identification of source velocities on 3D structures in non-anechoic environments: Theoretical background and experimental validation of the inverse patch transfer functions method

NASA Astrophysics Data System (ADS)

Aucejo, M.; Totaro, N.; Guyader, J.-L.

2010-08-01

In noise control, identification of the source velocity field remains a major problem open to investigation. Consequently, methods such as nearfield acoustical holography (NAH), principal source projection, the inverse frequency response function and hybrid NAH have been developed. However, these methods require free field conditions that are often difficult to achieve in practice. This article presents an alternative method known as inverse patch transfer functions, designed to identify source velocities and developed in the framework of the European SILENCE project. This method is based on the definition of a virtual cavity, the double measurement of the pressure and particle velocity fields on the aperture surfaces of this volume, divided into elementary areas called patches and the inversion of impedances matrices, numerically computed from a modal basis obtained by FEM. Theoretically, the method is applicable to sources with complex 3D geometries and measurements can be carried out in a non-anechoic environment even in the presence of other stationary sources outside the virtual cavity. In the present paper, the theoretical background of the iPTF method is described and the results (numerical and experimental) for a source with simple geometry (two baffled pistons driven in antiphase) are presented and discussed.

2004-09-01

Most of the critique in the A. Bandura and K. Bussey (see record 2004-18097-001) commentary is a misunderstanding or misrepresentation of the points made by C. L. Martin, D. N. Ruble, and J. Szkrybalo in their 2002 Psychological Bulletin article (see record 2002-18663-003). First, Martin et al. never intended to present a comprehensive theory; instead, it was a review of 2 different cognitive approaches to gender development. Second, there is no time line test that has been failed; instead, gender cognitions may occur earlier than initially believed. Third, Bandura and Bussey dismissed central gender cognitions-gender identity and gender stereotype knowledge-despite considerable evidence in their support. Fourth, Bandura and Bussey never addressed the gaps and ambiguities inherent in their theory that Martin et al. questioned in their earlier article. Finally, Bandura and Bussey's misunderstandings of cognitive theorists' views on socialization agents, sociocultural influences, agency, and motivation created theoretical rifts where none exist.

Practical sliced configuration spaces for curved planar pairs

Sacks, E.

1999-01-01

In this article, the author presents a practical configuration-space computation algorithm for pairs of curved planar parts, based on the general algorithm developed by Bajaj and the author. The general algorithm advances the theoretical understanding of configuration-space computation, but is too slow and fragile for some applications. The new algorithm solves these problems by restricting the analysis to parts bounded by line segments and circular arcs, whereas the general algorithm handles rational parametric curves. The trade-off is worthwhile, because the restricted class handles most robotics and mechanical engineering applications. The algorithm reduces run time by a factor of 60 onmore » nine representative engineering pairs, and by a factor of 9 on two human-knee pairs. It also handles common special pairs by specialized methods. A survey of 2,500 mechanisms shows that these methods cover 90% of pairs and yield an additional factor of 10 reduction in average run time. The theme of this article is that application requirements, as well as intrinsic theoretical interest, should drive configuration-space research.« less

A cultural accommodation model for cross-cultural psychotherapy: Illustrated with the case of Asian Americans.

Leong, Frederick T; Lee, Szu-Hui

2006-01-01

As an extension of F. T. L. Leong's (1996) integrative model, this article presents the cultural accommodation model (CAM), an enhanced theoretical guide to effective cross-cultural clinical practice and research. Whereas F. T. L. Leong's model identifies the importance of integrating the universal, group, and individual dimensions, the CAM takes the next step by providing a theoretical guide to effective psychotherapy with culturally different clients by means of a cultural accommodation process. This model argues for the importance of selecting and applying culture-specific constructs when working with culturally diverse groups. The first step of the CAM is to identify cultural disparities that are often ignored and then accommodate them by using current culturally specific concepts. In this article, several different cultural "gaps" or culture-specific constructs of relevance to Asian Americans with strong scientific foundations are selected and discussed as they pertain to providing effective psychotherapy to this ethnic minority group. Finally, a case study is incorporated to illustrate application of the CAM. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

2015-12-21

Although eye tracking has been used for decades, it has gained popularity in the area of sex research only recently. The aim of this article is to examine the potential merits of eye tracking for this field. We present a systematic review of the current use of video-based eye-tracking technology in this area, evaluate the findings, and identify future research opportunities. A total of 34 relevant studies published between 2006 and 2014 were identified for inclusion by means of online databases and other methods. We grouped them into three main areas of research: body perception and attractiveness, forensic research, and sexual orientation. Despite the methodological and theoretical differences across the studies, eye tracking has been shown to be a promising tool for sex research. The article suggests there is much potential for further studies to employ this technique because it is noninvasive and yet still allows for the assessment of both conscious and unconscious perceptional processes. Furthermore, eye tracking can be implemented in investigations of various theoretical backgrounds, ranging from biology to the social sciences.

An analytical study of the endoreversible Curzon-Ahlborn cycle for a non-linear heat transfer law

NASA Astrophysics Data System (ADS)

Páez-Hernández, Ricardo T.; Portillo-Díaz, Pedro; Ladino-Luna, Delfino; Ramírez-Rojas, Alejandro; Pacheco-Paez, Juan C.

2016-01-01

In the present article, an endoreversible Curzon-Ahlborn engine is studied by considering a non-linear heat transfer law, particularly the Dulong-Petit heat transfer law, using the `componendo and dividendo' rule as well as a simple differentiation to obtain the Curzon-Ahlborn efficiency as proposed by Agrawal in 2009. This rule is actually a change of variable that simplifies a two-variable problem to a one-variable problem. From elemental calculus, we obtain an analytical expression of efficiency and the power output. The efficiency is given only in terms of the temperatures of the reservoirs, such as both Carnot and Curzon-Ahlborn cycles. We make a comparison between efficiencies measured in real power plants and theoretical values from analytical expressions obtained in this article and others found in literature from several other authors. This comparison shows that the theoretical values of efficiency are close to real efficiency, and in some cases, they are exactly the same. Therefore, we can say that the Agrawal method is good in calculating thermal engine efficiencies approximately.

Violence is the main public health problem in Colombia. Many theoretical and methodological approaches to solving this problem have been attempted from different disciplines. My past work has focused on homicide violence from the perspective of social medicine. In this article I present the main conceptual and methodological aspects and the chief findings of my research over the past 15 years. Findings include a quantitative description of the current situation and the introduction of the category of explanatory contexts as a contribution to the study of Colombian violence. The complexity and severity of this problem demand greater theoretical discussion, more plans for action and a faster transition between the two. Social medicine may make a growing contribution to this field. PMID:14652328

Critical thinking as a self-regulatory process component in teaching and learning.

PubMed

Phan, Huy P

2010-05-01

This article presents a theoretically grounded model of critical thinking and self-regulation in the context of teaching and learning. Critical thinking, deriving from an educational psychology perspective is a complex process of reflection that helps individuals become more analytical in their thinking and professional development. My conceptualisation in this discussion paper argues that both theoretical orientations (critical thinking and self-regulation) operate in a dynamic interactive system of teaching and learning. My argument, based on existing research evidence, suggests two important points: (i) critical thinking acts as another cognitive strategy of self-regulation that learners use in their learning, and (ii) critical thinking may be a product of various antecedents such as different self-regulatory strategies.

Hamiltonian flow over saddles for exploring molecular phase space structures

NASA Astrophysics Data System (ADS)

Farantos, Stavros C.

2018-03-01

Despite using potential energy surfaces, multivariable functions on molecular configuration space, to comprehend chemical dynamics for decades, the real happenings in molecules occur in phase space, in which the states of a classical dynamical system are completely determined by the coordinates and their conjugate momenta. Theoretical and numerical results are presented, employing alanine dipeptide as a model system, to support the view that geometrical structures in phase space dictate the dynamics of molecules, the fingerprints of which are traced by following the Hamiltonian flow above saddles. By properly selecting initial conditions in alanine dipeptide, we have found internally free rotor trajectories the existence of which can only be justified in a phase space perspective. This article is part of the theme issue `Modern theoretical chemistry'.

Purpose Previous articles in this supplement described rationale for and development of the pause marker (PM), a diagnostic marker of childhood apraxia of speech (CAS), and studies supporting its validity and reliability. The present article assesses the theoretical coherence of the PM with speech processing deficits in CAS. Method PM and other scores were obtained for 264 participants in 6 groups: CAS in idiopathic, neurogenetic, and complex neurodevelopmental disorders; adult-onset apraxia of speech (AAS) consequent to stroke and primary progressive apraxia of speech; and idiopathic speech delay. Results Participants with CAS and AAS had significantly lower scores than typically speaking reference participants and speech delay controls on measures posited to assess representational and transcoding processes. Representational deficits differed between CAS and AAS groups, with support for both underspecified linguistic representations and memory/access deficits in CAS, but for only the latter in AAS. CAS–AAS similarities in the age–sex standardized percentages of occurrence of the most frequent type of inappropriate pauses (abrupt) and significant differences in the standardized occurrence of appropriate pauses were consistent with speech processing findings. Conclusions Results support the hypotheses of core representational and transcoding speech processing deficits in CAS and theoretical coherence of the PM's pause-speech elements with these deficits.

The Strategic Management of Store Brand Perceived Quality

NASA Astrophysics Data System (ADS)

Yang, Defeng

Store brand plays a vital role in the success of retailers. Perceived quality is one of important factors influencing consumers' store brand purchase intention. Store brand perceived quality is lower compared with objective quality or national brand. For this end, the purpose of this article is to examine how to manage store brand perceived quality in strategic level. This article firstly discusses how consumers evaluate product quality, and the theoretical background of the reason that store brand perceived quality is lower from the view of cue related theories. Then, consumers' store brand quality evaluation is explored. Finally, this article presents several strategic tactics to increase store brand perceived quality. These tactics include choosing store's name as store brand name, making large advertising investment, improving store brand product package, and strengthening the relationship with store brand product suppliers.

Symbol signal-to-noise ratio loss in square-wave subcarrier downconversion

NASA Technical Reports Server (NTRS)

Feria, Y.; Statman, J.

1993-01-01

This article presents the simulated results of the signal-to-noise ratio (SNR) loss in the process of a square-wave subcarrier down conversion. In a previous article, the SNR degradation was evaluated at the output of the down converter based on the signal and noise power change. Unlike in the previous article, the SNR loss is defined here as the difference between the actual and theoretical symbol SNR's for the same symbol-error rate at the output of the symbol matched filter. The results show that an average SNR loss of 0.3 dB can be achieved with tenth-order infinite impulse response (IIR) filters. This loss is a 0.2-dB increase over the SNR degradation in the previous analysis where neither the signal distortion nor the symbol detector was considered.

Following article presents LIDAR for stand off detection of aerosols which was constructed in Institute of Optoelectronics in Military University of Technology. LIDAR is a DISC type system (DIfferential SCattering) and is based on analysis of backscattering signal for two wavelengths (λ1 = 1064 nm and λ2 = 532 nm) - the first and the second harmonic of Nd:YAG laser. Optical receiving system is consisted of aspherical mirror lens, two additional mirrors and a system of interference filters. In detection system of LIDAR a silicon avalanche photodiode and two different amplifiers were used. Whole system is mounted on a specialized platform designed for possibility of LIDAR scanning movements. LIDAR is computer controlled. The compiled software enables regulation of the scanning platform work, gain control, and control of data processing and acquisition system. In the article main functional elements of LIDAR are shown and typical parameters of system work and construction are presented. One presented also first results of research with use of LIDAR. The aim of research was to detect and characterize scattering aerosol, both natural and anthropogenic one. For analyses of natural aerosols, cumulus cloud was used. For analyses of anthropogenic aerosols one used three various pyrotechnic mixtures (DM11, M2, M16) which generate smoke of different parameters. All scattering centers were firstly well described and theoretical analyses were conducted. Results of LIDAR research were compared with theoretical analyses and general conclusions concerning correctness of LIDAR work and its application were drawn.

Upscaling the number of learners, fragmenting the role of teachers: How do massive open online courses (MOOCs) form new conditions for learning design?

NASA Astrophysics Data System (ADS)

Buhl, Mie; Andreasen, Lars Birch; Pushpanadham, Karanam

2018-03-01

The proliferation and expansion of massive open online courses (MOOCs) prompts a need to revisit classical pedagogical questions. In what ways will MOOCs facilitate and promote new e-learning pedagogies? Is current learning design adequate for the "massiveness" and "openness" of MOOCs? This article discusses the ways in which MOOCs create new conditions for designing learning processes. The authors present various theoretical approaches to learning design and discuss a combination of theoretical perspectives. They discern a fragmentation of the teacher role; where the teacher was once the main person responsible for planning, practice and reflection, those activities may now be performed by different actors with different areas of responsibility. The theoretical discussion is complemented by a review of recent studies of new practices and design formats aiming to overcome the upscaling issues of MOOCs. The authors present a multifaceted picture of MOOC methodologies, including a typology of hybrid approaches to MOOC design. Through the example of MOOC implementation in India, they address the integration of MOOCs into formal higher education systems. They conclude their article with the contention that, through upscaling, important facets of students' intellectual development and critical thinking might be left to the students themselves. This may cause problems. Adequate scaffolding from a teacher, such as adapting activities to the specific situation, might be needed to develop the skills required to be a self-directed learner. Furthermore, upscaling seems to promote a separation of the formerly unified teacher functions of planning, teaching and assessing, which necessitates increased collaboration among the many new actors in the field of pedagogy.

2017-01-01

A possibility of quality improvement of stabilization of rotation frequency of the gas-diesels used as prime mover of generator set in the multigenerator units working for abruptly variable load of large power is considered. An evaluation is made on condition of fuzzy controller use developed and described by the authors in a number of articles. An evaluation has shown that theoretically, the revolution range of gas-diesel engine may be reduced at 25-30 times at optimal settings of the controller in all the power range. The results of modeling showing a considerable quality improvement of transient processes in the investigated system at a sharp change of loading are presented in this article.

Little-known truths, quirky anecdotes, seething scandals, and even some science in the history of (primarily achievement) motivation.

Weiner, Bernard

2013-08-01

This article presents a history of the study of motivation from approximately 1900-1975, focusing on achievement strivings and containing little-known and often surprising facts about the main contributors to this field. Four theorists are highlighted: David McClelland, Kurt Lewin, John Atkinson, and Fritz Heider, each associated with a different theoretical approach (respectively and in order of historical emergence: trait, Gestalt, expectancy/value, and attribution theory). A fifth conception, drive theory, is also represented. In addition, a number of individuals who influenced these theorists and others who followed them are discussed. The article emphasizes the interrelations between the theorists and the interaction between personal and scientific life.

Theoretical verification of nonthermal microwave effects on intramolecular reactions.

PubMed

Kanno, Manabu; Nakamura, Kosuke; Kanai, Eri; Hoki, Kunihito; Kono, Hirohiko; Tanaka, Motohiko

2012-03-08

There have been a growing number of articles that report dramatic improvements in the experimental performance of chemical reactions by microwave irradiation compared to that under conventional heating conditions. We theoretically examined whether nonthermal microwave effects on intramolecular reactions exist or not, in particular, on Newman-Kwart rearrangements and intramolecular Diels-Alder reactions. The reaction rates of the former calculated by the transition state theory, which consider only the thermal effects of microwaves, agree quantitatively with experimental data, and thus, the increases in reaction rates can be ascribed to dielectric heating of the solvent by microwaves. In contrast, for the latter, the temperature dependence of reaction rates can be explained qualitatively by thermal effects but the possibility of nonthermal effects still remains regardless of whether competitive processes are present or not. The effective intramolecular potential energy surface in the presence of a microwave field suggests that nonthermal effects arising from potential distortion are vanishingly small in intramolecular reactions. It is useful in the elucidation of the reaction mechanisms of microwave synthesis to apply the present theoretical approach with reference to the experiments where thermal and nonthermal effects are separated by screening microwave fields.

Theoretical and Empirical Analysis of a Spatial EA Parallel Boosting Algorithm.

PubMed

Kamath, Uday; Domeniconi, Carlotta; De Jong, Kenneth

2018-01-01

Many real-world problems involve massive amounts of data. Under these circumstances learning algorithms often become prohibitively expensive, making scalability a pressing issue to be addressed. A common approach is to perform sampling to reduce the size of the dataset and enable efficient learning. Alternatively, one customizes learning algorithms to achieve scalability. In either case, the key challenge is to obtain algorithmic efficiency without compromising the quality of the results. In this article we discuss a meta-learning algorithm (PSBML) that combines concepts from spatially structured evolutionary algorithms (SSEAs) with concepts from ensemble and boosting methodologies to achieve the desired scalability property. We present both theoretical and empirical analyses which show that PSBML preserves a critical property of boosting, specifically, convergence to a distribution centered around the margin. We then present additional empirical analyses showing that this meta-level algorithm provides a general and effective framework that can be used in combination with a variety of learning classifiers. We perform extensive experiments to investigate the trade-off achieved between scalability and accuracy, and robustness to noise, on both synthetic and real-world data. These empirical results corroborate our theoretical analysis, and demonstrate the potential of PSBML in achieving scalability without sacrificing accuracy.

Historic perspectives from anthropology. Reflections proposed to Transcultural Nursing.

PubMed

Rohrbach Viadas, Cecilia

2015-01-01

History brings together meanings related to earlier periods, being aware of the past as a panorama to reread the present. Madeleine Leininger presented in 1970 an implicit and respectful message to the Nursing Profession when introducing Nursing and Anthropology. Two Worlds to Blend. Implicitly: Nursing you disregard culture. This article shows the absence of the history of anthropology and of nursing within Transcultural Nursing and it includes how education has influenced theoretic, methodological, and comparative approaches giving researchers the responsibility to decide their fundamentals. Berthoud (2001) has inspired the anthropological and historic perspectives of the author, thus universalism, relativism, and comparison are presented.

The effects of list-method directed forgetting on recognition memory.

PubMed

Benjamin, Aaron S

2006-10-01

It is an almost universally accepted claim that the list-method procedure of inducing directed forgetting does not affect recognition. However, previous studies have omitted a critical comparison in reaching this conclusion. This article reports evidence that recognition of material learned after cue presentation is superior for conditions in which the material that preceded cue presentation was designated as to-be-forgotten. Because the absence of an effect of directed-forgetting instructions on recognition is the linchpin of the theoretical claim that retrieval inhibition and not selective rehearsal underlies that effect, the present results call into question the need to postulate a role for inhibition in directed forgetting.

We conducted a study designed to evaluate the efficacy and feasibility of a multilevel self-management intervention to improve nutritional intake in a group of older adults receiving Medicare home health services who were at especially high risk for experiencing undernutrition. The Behavioral Nutrition Intervention for Community Elders (B-NICE) trial used a prospective randomized controlled design to determine whether individually tailored counseling focused on social and behavioral aspects of eating resulted in increased caloric intake and improved nutrition-related health outcomes in a high-risk population of older adults. The study was guided by the theoretical approaches of the Ecological Model and Social Cognitive Theory. The development and implementation of the B-NICE protocol, including the theoretical framework, methodology, specific elements of the behavioral intervention, and assurances of the treatment fidelity, as well as the health policy implications of the trial results, are presented in this article.

Kinetics and dynamics of near-resonant vibrational energy transfer in gas ensembles of atmospheric interest

NASA Astrophysics Data System (ADS)

McCaffery, Anthony J.

2018-03-01

This study of near-resonant, vibration-vibration (V-V) gas-phase energy transfer in diatomic molecules uses the theoretical/computational method, of Marsh & McCaffery (Marsh & McCaffery 2002 J. Chem. Phys. 117, 503 (doi:10.1063/1.1489998)) The method uses the angular momentum (AM) theoretical formalism to compute quantum-state populations within the component molecules of large, non-equilibrium, gas mixtures as the component species proceed to equilibration. Computed quantum-state populations are displayed in a number of formats that reveal the detailed mechanism of the near-resonant V-V process. Further, the evolution of quantum-state populations, for each species present, may be followed as the number of collision cycles increases, displaying the kinetics of evolution for each quantum state of the ensemble's molecules. These features are illustrated for ensembles containing vibrationally excited N2 in H2, O2 and N2 initially in their ground states.

Affectionate Touch to Promote Relational, Psychological, and Physical Well-Being in Adulthood: A Theoretical Model and Review of the Research.

PubMed

Jakubiak, Brittany K; Feeney, Brooke C

2017-08-01

Throughout the life span, individuals engage in affectionate touch with close others. Touch receipt promotes well-being in infancy, but the impacts of touch in adult close relationships have been largely unexplored. In this article, we propose that affectionate touch receipt promotes relational, psychological, and physical well-being in adulthood, and we present a theoretical mechanistic model to explain why affectionate touch may promote these outcomes. The model includes pathways through which touch could affect well-being by reducing stress and by promoting well-being independent of stress. Specifically, two immediate outcomes of affectionate touch receipt-relational-cognitive changes and neurobiological changes-are described as important mechanisms underlying the effects of affectionate touch on well-being. We also review and evaluate the existing research linking affectionate touch to well-being in adulthood and propose an agenda to advance research in this area. This theoretical perspective provides a foundation for future work on touch in adult close relationships.

Roth, Wolff-Michael

2012-09-01

The feature article discussed in this forum presents an interesting description of how students work in the context of a virtual world, where they design phenomena that they subsequently investigate by analyzing graphical representations. The study is aligned with the current canon of science education interested in understanding the inter-psychological and intra-psychological determinants of learning. Its main focus is on "meaning making." In this contribution to the forum, I articulate some shortcomings inherent in this theoretical notion, which, in essence, hides rather than reveals the real issues in and of learning. I offer some alternative avenues, both theoretical and methodological, for framing pertinent issues; in so doing, I (endeavor to) open up new avenues for research in science education. In essence, therefore, I offer possible avenues in response to the question, "What more can there be done by science education research?" that would allow us to eschew what I perceive to be hidden contradictions that interfere with making theoretical and practical advances in our field.

Intellect: a theoretical framework for personality traits related to intellectual achievements.

PubMed

Mussel, Patrick

2013-05-01

The present article develops a theoretical framework for the structure of personality traits related to intellectual achievements. We postulate a 2-dimensional model, differentiating between 2 processes (Seek and Conquer) and 3 operations (Think, Learn, and Create). The framework was operationalized by a newly developed measure, which was validated based on 2 samples. Subsequently, in 3 studies (overall N = 1,478), the 2-dimensional structure of the Intellect framework was generally supported. Additionally, subdimensions of the Intellect framework specifically predicted conceptually related criteria, including scholastic performance, vocational interest, and leisure activities. Furthermore, results from multidimensional scaling and higher order confirmatory factor analyses show that the framework allows for the incorporation of several constructs that have been proposed on different theoretical backgrounds, such as need for cognition, typical intellectual engagement, curiosity, intrinsic motivation, goal orientation, and openness to ideas. It is concluded that based on the Intellect framework, these constructs, which have been researched separately in the literature, can be meaningfully integrated.

There are known only few ballistic object tracking algorithms. To develop such algorithms and to its further testing, it is necessary to implement possibly simple and reliable objects' dynamics model. The article presents the dynamics' model of a tactical ballistic missile (TBM) including the three stages of flight: the boost stage and two passive stages - the ascending one and the descending one. Additionally, the procedure of transformation from the local coordinate system to the polar-radar oriented and the global is presented. The prepared theoretical data may be used to determine the tracking algorithm parameters and to its further verification.

Antireflective coatings for multijunction solar cells under wide-angle ray bundles.

PubMed

Victoria, Marta; Domínguez, César; Antón, Ignacio; Sala, Gabriel

2012-03-26

Two important aspects must be considered when optimizing antireflection coatings (ARCs) for multijunction solar cells to be used in concentrators: the angular light distribution over the cell created by the particular concentration system and the wide spectral bandwidth the solar cell is sensitive to. In this article, a numerical optimization procedure and its results are presented. The potential efficiency enhancement by means of ARC optimization is calculated for several concentrating PV systems. In addition, two methods for ARCs direct characterization are presented. The results of these show that real ARCs slightly underperform theoretical predictions.

General framework for constraints in molecular dynamics simulations

NASA Astrophysics Data System (ADS)

Kneller, Gerald R.

2017-06-01

The article presents a theoretical framework for molecular dynamics simulations of complex systems subject to any combination of holonomic and non-holonomic constraints. Using the concept of constrained inverse matrices both the particle accelerations and the associated constraint forces can be determined from given external forces and kinematical conditions. The formalism enables in particular the construction of explicit kinematical conditions which lead to the well-known Nosé-Hoover type equations of motion for the simulation of non-standard molecular dynamics ensembles. Illustrations are given for a few examples and an outline is presented for a numerical implementation of the method.

Parallel Distractor Rejection as a Binding Mechanism in Search

PubMed Central

Dent, Kevin; Allen, Harriet A.; Braithwaite, Jason J.; Humphreys, Glyn W.

2012-01-01

The relatively common experimental visual search task of finding a red X amongst red O’s and green X’s (conjunction search) presents the visual system with a binding problem. Illusory conjunctions (ICs) of features across objects must be avoided and only features present in the same object bound together. Correct binding into unique objects by the visual system may be promoted, and ICs minimized, by inhibiting the locations of distractors possessing non-target features (e.g., Treisman and Sato, 1990). Such parallel rejection of interfering distractors leaves the target as the only item competing for selection; thus solving the binding problem. In the present article we explore the theoretical and empirical basis of this process of active distractor inhibition in search. Specific experiments that provide strong evidence for a process of active distractor inhibition in search are highlighted. In the final part of the article we consider how distractor inhibition, as defined here, may be realized at a neurophysiological level (Treisman and Sato, 1990). PMID:22908002

This is the first of a series of reflections on a trip a group of nurses made to China in June 1994. John Douglas, a science writer who accompanied the group, wrote the first article in this series. He shares his reflections on the Chinese health care system and interviews conducted with several Chinese nurses. Dr. Grayce Roessler, an internationally known transcultural nursing leader, directed the tour. She has traveled extensively in China (some 30 trips over twenty years) and has worked with Chinese nurses to establish transcultural educational exchange programs between the United States and China. In a future issue of this journal, Dr. Roessler will present her reflections on nursing in China from a transcultural nursing leader's perspective. In the final article in this series Dr. Julianna Finn, a transcultural nurse educator who also made this trip, will present some reflections on nursing in China from a transcultural nursing theoretical perspective using Leininger's Culture Care Theory.

Efforts are made to identify methods of decreasing magnetic interpretation ambiguity by combined gravity and magnetic analysis, to evaluate these techniques in a preliminary manner, to consider the geologic and geophysical implications of correlation, and to recommend a course of action to evaluate methods of correlating gravity and magnetic anomalies. The major thrust of the study was a search and review of the literature. The literature of geophysics, geology, geography, and statistics was searched for articles dealing with spatial correlation of independent variables. An annotated bibliography referencing the Germane articles and books is presented. The methods of combined gravity and magnetic analysis techniques are identified and reviewed. A more comprehensive evaluation of two types of techniques is presented. Internal correspondence of anomaly amplitudes is examined and a combined analysis is done utilizing Poisson's theorem. The geologic and geophysical implications of gravity and magnetic correlation based on both theoretical and empirical relationships are discussed.

Extreme violence events are consequence of current world-wide economic, political and social conditions. Injury patterns found among victims of extreme violence events are very complex, obeying several high-energy injury mechanisms. In this article, we present the basic concepts of trauma kinematics that regulate the clinical approach to victims of extreme violence events, in the hope that clinicians increase their theoretical armamentarium, and reflecting on obtaining better outcomes.

Utility of pedometers for assessing physical activity: construct validity.

Tudor-Locke, Catrine; Williams, Joel E; Reis, Jared P; Pluto, Delores

2004-01-01

Valid assessment of physical activity is necessary to fully understand this important health-related behaviour for research, surveillance, intervention and evaluation purposes. This article is the second in a companion set exploring the validity of pedometer-assessed physical activity. The previous article published in Sports Medicine dealt with convergent validity (i.e. the extent to which an instrument's output is associated with that of other instruments intended to measure the same exposure of interest). The present focus is on construct validity. Construct validity is the extent to which the measurement corresponds with other measures of theoretically-related parameters. Construct validity is typically evaluated by correlational analysis, that is, the magnitude of concordance between two measures (e.g. pedometer-determined steps/day and a theoretically-related parameter such as age, anthropometric measures and fitness). A systematic literature review produced 29 articles published since > or =1980 directly relevant to construct validity of pedometers in relation to age, anthropometric measures and fitness. Reported correlations were combined and a median r-value was computed. Overall, there was a weak inverse relationship (median r = -0.21) between age and pedometer-determined physical activity. A weak inverse relationship was also apparent with both body mass index and percentage overweight (median r = -0.27 and r = -0.22, respectively). Positive relationships regarding indicators of fitness ranged from weak to moderate depending on the fitness measure utilised: 6-minute walk test (median r = 0.69), timed treadmill test (median r = 0.41) and estimated maximum oxygen uptake (median r = 0.22). Studies are warranted to assess the relationship of pedometer-determined physical activity with other important health-related outcomes including blood pressure and physiological parameters such as blood glucose and lipid profiles. The aggregated evidence of convergent validity (presented in the previous companion article) and construct validity herein provides support for considering simple and inexpensive pedometers in both research and practice.

[A unit for emergency psychiatry and crisis intervention--concepts, structure and initial experiences].

Feuerlein, W; Bronisch, T; Fürmaier, A

1983-03-01

The article reports on a ward with 12 beds which has been set up for emergency cases in psychiatry or for immediate intervention in case of a crisis experienced by a patient. In the theoretical part of this article, it is explained that crisis situations are present in most of the psychiatric emergency patients. The article then goes briefly into the fundamentals of therapeutic strategy in such patients: A therapy which helps to uncover hidden conflicts, the pros and cons of therapy focussed on conflict and on supportive measures; as well as a therapy which supports and promotes the ego. This is followed by a comparison of the ward with corresponding facilities in Germany and abroad and a description of their structure, their patients and their function within a psychiatric care system. The concluding part of the article is devoted to a description of the authors' initial experiences and impressions gained during their work with the ward patients, quoting several examples.

Heightened fiscal constraints, increases in the chronic disease burden and in consumer expectations are among several factors contributing to the global interest in evidence-informed health policy. The present article builds on previous work that explored how the Australian Federal Government applied five instruments of policy, or policy levers, to implement a series of reforms under the Australian National Mental Health Strategy (NMHS). The present article draws on theoretical insights from political science to analyse the relative successes and failures of these levers, as portrayed in formal government evaluations of the NMHS. Documentary analysis of six evaluation documents corresponding to three National Mental Health Plans was undertaken. Both the content and approach of these government-funded, independently conducted evaluations were appraised. An overall improvement was apparent in the development and application of policy levers over time. However, this finding should be interpreted with caution due to variations in evaluation approach according to Plan and policy lever. Tabulated summaries of the success and failure of each policy initiative, ordered by lever type, are provided to establish a resource that could be consulted for future policy-making. This analysis highlights the complexities of health service reform and underscores the limitations of narrowly focused empirical approaches. A theoretical framework is provided that could inform the evaluation and targeted selection of appropriate policy levers in mental health.

Patient Autonomy in a High-Tech Care Context - A Theoretical Framework.

PubMed

Lindberg, Catharina; Fagerström, Cecilia; Willman, Ania

2018-06-12

To synthesise and interpret previous findings with the aim of developing a theoretical framework for patient autonomy in a high-tech care context. Putting the somewhat abstract concept of patient autonomy into practice can prove difficult since when it is highlighted in healthcare literature the patient perspective is often invisible. Autonomy presumes that a person has experience, education, self-discipline and decision-making capacity. Reference to autonomy in relation to patients in high-tech care environments could therefore be considered paradoxical, as in most cases these persons are vulnerable, with impaired physical and/or metacognitive capacity, thus making extended knowledge of patient autonomy for these persons even more important. Theory development. The basic approaches in theory development by Walker and Avant were used to create a theoretical framework through an amalgamation of the results from three qualitative studies conducted previously by the same research group. A theoretical framework - the control-partnership-transition framework - was delineated disclosing different parts co-creating the prerequisites for patient autonomy in high-tech care environments. Assumptions and propositional statements that guide theory development were also outlined, as were guiding principles for use in day-to-day nursing care. Four strategies used by patients were revealed: the strategy of control, the strategy of partnership, the strategy of trust, and the strategy of transition. An extended knowledge base, founded on theoretical reasoning about patient autonomy, could facilitate nursing care that would allow people to remain/become autonomous in the role of patient in high-tech care environments. The control-partnership-transition framework would be of help in supporting and defending patient autonomy when caring for individual patients, as it provides an understanding of the strategies employed by patients to achieve autonomy in high-tech care contexts. The guiding principles for patient autonomy presented could be used in nursing guidelines. This article is protected by copyright. All rights reserved. This article is protected by copyright.

2010-10-01

Recently published articles have described criteria to assess qualitative research in the health field in general, but very few articles have delineated qualitative methods to be used in the development of Patient-Reported Outcomes (PROs). In fact, how PROs are developed with subject input through focus groups and interviews has been given relatively short shrift in the PRO literature when compared to the plethora of quantitative articles on the psychometric properties of PROs. If documented at all, most PRO validation articles give little for the reader to evaluate the content validity of the measures and the credibility and trustworthiness of the methods used to develop them. Increasingly, however, scientists and authorities want to be assured that PRO items and scales have meaning and relevance to subjects. This article was developed by an international, interdisciplinary group of psychologists, psychometricians, regulatory experts, a physician, and a sociologist. It presents rigorous and appropriate qualitative research methods for developing PROs with content validity. The approach described combines an overarching phenomenological theoretical framework with grounded theory data collection and analysis methods to yield PRO items and scales that have content validity.

Non-extensitivity vs. informative moments for financial models —A unifying framework and empirical results

Herrmann, K.

2009-11-01

Information-theoretic approaches still play a minor role in financial market analysis. Nonetheless, there have been two very similar approaches evolving during the last years, one in the so-called econophysics and the other in econometrics. Both generalize the notion of GARCH processes in an information-theoretic sense and are able to capture kurtosis better than traditional models. In this article we present both approaches in a more general framework. The latter allows the derivation of a wide range of new models. We choose a third model using an entropy measure suggested by Kapur. In an application to financial market data, we find that all considered models - with similar flexibility in terms of skewness and kurtosis - lead to very similar results.

The interrogation decision-making model: A general theoretical framework for confessions.

PubMed

Yang, Yueran; Guyll, Max; Madon, Stephanie

2017-02-01

This article presents a new model of confessions referred to as the interrogation decision-making model . This model provides a theoretical umbrella with which to understand and analyze suspects' decisions to deny or confess guilt in the context of a custodial interrogation. The model draws upon expected utility theory to propose a mathematical account of the psychological mechanisms that not only underlie suspects' decisions to deny or confess guilt at any specific point during an interrogation, but also how confession decisions can change over time. Findings from the extant literature pertaining to confessions are considered to demonstrate how the model offers a comprehensive and integrative framework for organizing a range of effects within a limited set of model parameters.

Theoretical and behavioral features to be considered when planning and implementing a pbl curriculum.

D' Ottavio, Alberto Enrique

2016-01-01

This work complements former articles about an Argentinean PBL curriculum after twelve years of development. In this context, it points out determined inflexible features linked to its theoretical-pedagogical basis and certain counter-productive behaviors detected in some planners, teachers and students during its design and/or enduring implementation. Hence, reflections are made on learning and adult learning (andragogy) theories. Furthermore, related questions and some aspects to be overcome are presented and analyzed. In this way, it also intends to honestly and responsibly warn well-trained curriculum planners and executors to be cautious when choosing and managing learning theories. Likewise, it complementarily highlights the need of refocusing teachers that, pretending to be forward-looking ones, end up harming what at first proclaimed to benefit: the students.

Finding and defining the natural automata acting in living plants: Toward the synthetic biology for robotics and informatics in vivo.

The automata theory is the mathematical study of abstract machines commonly studied in the theoretical computer science and highly interdisciplinary fields that combine the natural sciences and the theoretical computer science. In the present review article, as the chemical and biological basis for natural computing or informatics, some plants, plant cells or plant-derived molecules involved in signaling are listed and classified as natural sequential machines (namely, the Mealy machines or Moore machines) or finite state automata. By defining the actions (states and transition functions) of these natural automata, the similarity between the computational data processing and plant decision-making processes became obvious. Finally, their putative roles as the parts for plant-based computing or robotic systems are discussed.

Theoretical and experimental examination of near-field acoustic levitation.

PubMed

Nomura, Hideyuki; Kamakura, Tomoo; Matsuda, Kazuhisa

2002-04-01

A planar object can be levitated stably close to a piston sound source by making use of acoustic radiation pressure. This phenomenon is called near-field acoustic levitation [Y. Hashimoto et al., J. Acoust. Soc. Am. 100, 2057-2061 (1996)]. In the present article, the levitation distance is predicted theoretically by numerically solving basic equations in a compressible viscous fluid subject to the appropriate initial and boundary conditions. Additionally, experiments are carried out using a 19.5-kHz piston source with a 40-mm aperture and various aluminum disks of different sizes. The measured levitation distance agrees well with the theory, which is different from a conventional theory, and the levitation distance is not inversely proportional to the square root of the surface density of the levitated disk in a strict sense.

Culture, personal experience and agency.

PubMed

McCarthy, John; Sullivan, Paul; Wright, Peter

2006-06-01

In this article, we explore what we perceive to be a gap between agency as articulated in practice theories and agency as personally experienced. The gap is not created by a turn to practice in theorizing, but by the tendency to produce theoretical representations that silence the particularity of experience and the diversity of voices in experience. In exploring the gap, we identify aspects of practice theories that explicitly commit to theoretical representation over personal experience and describe Bakhtin's commitment to action and personal experience as an alternative. In order to exemplify Bakhtin's approach in practice, we then present an analysis of one artist-teacher's experience of her own agency in making art and in teaching. Finally, we comment on what a commitment to representational theorizing does to accounts of an artist's activities and personal experience.

The no conclusion intervention for couples in conflict.

PubMed

Migerode, Lieven

2014-07-01

Dealing with difference is central to all couple therapy. This article presents an intervention designed to assist couples in handling conflict. Central to this approach is the acceptance that most conflicts cannot be solved. Couples are in need of a different understanding of couples conflict. This understanding is found in the analysis of love in context and in relational dialectics. Couples are guided through different steps: deciding on the valence of the issue as individuals, helping them decide which differences can be resolved and which issues demand new ways of living with the inevitable, and the introduction in the suggested no conclusion dialogue. This article briefly describes the five day intensive couple therapy program, in which the no intervention is embedded. The theoretical foundation of the intervention, followed by the step by step description of the intervention forms the major part of the article. A case vignette illustrates this approach. © 2012 American Association for Marriage and Family Therapy.

2006-09-01

Selected studies with specific relevance to substance abuse prevention interventions with Hispanic youth and families were examined to identify prior findings and emerging issues that may guide the design of future substance abuse prevention intervention research and its implementation with Hispanic populations. The origins of prevention research and role of risk and protective factors are examined, including culturally-specific risk and protective factors for Hispanic populations. Correlational studies, non-experimental interventions, and randomized controlled trials were examined for the period of 1974-2003. The literature search yielded 15 articles selected for this review that exhibited adequate methodological rigor. An added search for more recent studies identified three additional articles, for a total of 18 prevention intervention articles that were reviewed. Theoretical and methodological issues and recommendations are presented for future research aimed at improving the efficacy and effectiveness of future prevention intervention studies and their cultural relevance for Hispanic populations.
