Cultural evolutionary theory is an interdisciplinary field in which human culture is viewed as a Darwinian process of variation, competition, and inheritance, and the tools, methods, and theories developed by evolutionary biologists to study genetic evolution are adapted to study cultural change. It is argued here that an integration of the theories and findings of mainstream social psychology and of cultural evolutionary theory can be mutually beneficial. Social psychology provides cultural evolution with a set of empirically verified microevolutionary cultural processes, such as conformity, model-based biases, and content biases, that are responsible for specific patterns of cultural change. Cultural evolutionary theory provides social psychology with ultimate explanations for, and an understanding of the population-level consequences of, many social psychological phenomena, such as social learning, conformity, social comparison, and intergroup processes, as well as linking social psychology with other social science disciplines such as cultural anthropology, archaeology, and sociology.

CULTURAL GLOBALISATION AND CHALLENGES TO TRADITIONAL COMMUNICATION THEORIES

Directory of Open Access Journals (Sweden)

Lauren Movius

2010-01-01

Full Text Available This article reviews existing traditional media theories, and analyses the challenges that the current developments of globalisation present to them. The article provides a short history of the concept of globalisation, and reviews the primary theoretical approaches to globalisation that are critical to communication scholars. The article also examines how globalisation challenges the ways in which media and communication have traditionally been theorised. Specifically, the cultural imperialism theory is discussed, as well as the main challenges to the theory. Audience reception studies, which focus on how audiences negotiate meaning differently in specific cultural contexts, are highlighted as the key critique of cultural imperialism

The Culture Care theory and the Old Order Amish.

Science.gov (United States)

Wenger, A F

1991-11-01

This chapter discussed knowledge about culture care and culture context in relation to Old Order Amish culture. Leininger's theory of Cultural Care Diversity and Universality and Hall's concept of high-context culture were used to study culture care of the Old Order Amish. This study provided new findings about the culture, especially as related to culture care and high context. These findings also are important to guide nurses and other health care professionals in providing culture-specific care to the Old Order Amish. Leininger's Cultural Care theory has provided a comprehensive theoretical framework to explicate embedded care constructs and patterns of daily living within this culture. Hall's concepts helped to value and discover the importance of high context within the Old Order Amish culture and its relation to the phenomenon of care.

Occupation, well-being, and culture: Theory and cultural humility.

Science.gov (United States)

Hammell, Karen R Whalley

2013-10-01

The Canadian Model of Occupational Performance and Engagement depicts individuals embedded within cultural environments that afford occupational possibilities. Culture pertains not solely to ethnicity or race but to any dimension of diversity, including class, gender, sexual orientation, and ability. This paper highlights specific dimensions of cultural diversity and their relationships to occupational engagement and well-being. Cultural variations constitute the basis for a socially constructed hierarchy of traits that significantly determine occupational opportunities and impact mental health and well-being. Cultural humility is an approach to redressing power imbalances in client-therapist relationships by incorporating critical self-evaluation and recognizing that cultural differences lie not within clients but within client-therapist relationships. It is proposed that theoretical relevance would be enhanced if culturally diverse perspectives were incorporated into theories of occupation. Cultural humility is advocated as an approach to theoretical development and in efforts to counter professional Eurocentrism, ethnocentrism, and intellectual colonialism.

Working With Cultural-Historical Activity Theory

Directory of Open Access Journals (Sweden)

Wolff-Michael Roth

2012-05-01

Full Text Available This article focuses on the experiences of two researchers, Wolff-Michael ROTH and Luis RADFORD, using cultural-historical activity theory in mathematics education. The aim is to provide insights into the ways these researchers see and engage with activity theory, how they have come to adopt and expand it, and some of the challenges and concerns that they have had using it. These questions are not usually addressed within typical scientific papers. Yet, they are important for understanding both the dynamics of research and the practical use of cultural-historical activity theory. Since the format of research report papers is not necessarily well suited to convey personal experiences and thinking, the present article takes the form of a conversation, which provides an effective vehicle for exploring and articulating these matters. This provides a basis for understanding more deeply the underlying assumptions of this theory; its dynamics and how it is applied in research of mathematics practice, thinking, and learning; and insights into the manner in which experienced researchers grapple with the theoretical dimensions of their research.

Type II pp-wave matrix models from point-like gravitons

International Nuclear Information System (INIS)

Lozano, Yolanda; RodrIguez-Gomez, Diego

2006-01-01

The BMN Matrix model can be regarded as a theory of coincident M-theory gravitons, which expand by Myers dielectric effect into the 2-sphere and 5-sphere giant graviton vacua of the theory. In this note we show that, in the same fashion, Matrix String theory in Type IIA pp-wave backgrounds arises from the action for coincident Type IIA gravitons. In Type IIB, we show that the action for coincident gravitons in the maximally supersymmetric pp-wave background gives rise to a Matrix model which supports fuzzy 3-sphere giant graviton vacua with the right behavior in the classical limit. We discuss the relation between our Matrix model and the Tiny Graviton Matrix theory

Literature on the periphery of capitalism: Brazilian theory, Canadian culture Literature on the periphery of capitalism: Brazilian theory, Canadian culture

Full Text Available In order to get past the blind spots that have developed in contemporary postcolonial theory, it is essential to seek out complementarities and solidarities in different national situations and in different modernities. This essay undertakes this task by exploring the homologous situations faced in Brazil and Canada in their respective attempts to create genuine national cultures. As in many postcolonial situations, the problem of creating an authentic culture is directly related to the sense that postcolonial culture is necessarily imitative and belated. In Misplaced Ideas, Roberto Schwarz exposes the hidden class character of the problem of cultural authenticity in Brazil, and in so doing, shows that the trauma of national-cultural identity merely reflects the contradictory structural position of Brazil’s postcolonial elite. Using Schwarz’s insights to explore the Canadian situation, the author shows that the same forces are at work in Canada. Though the crisis of a lack of an authentic Canadian culture has recently been surmounted as a result of the apparent international success of Canadian culture (especially literary fiction, that author cautions that this “success” story hides the class basis of Canadian culture in both its belated and isochronic phases (the latter being the moment when cultural belatedness is overcome. Making use of Brazilian theory to examine problems in Canadian culture allows us to see that Canadian modernity, long thought to be simply a derivative of the UK and USA, has similarities with Brazilian modernity that are essential to understanding the space and place Canada occupies in globalization. In order to get past the blind spots that have developed in contemporary postcolonial theory, it is essential to seek out complementarities and solidarities in different national situations and in different modernities.

Use of the Culture Care Theory and ethnonursing method to discover how nursing faculty teach culture care.

Science.gov (United States)

Mixer, Sandra J

2008-04-01

As the world becomes increasingly multicultural, transcultural nursing education is critical to ensuring a culturally competent workforce. This paper presents a comprehensive review of literature and results of an ethnonursing pilot study using the Culture Care Theory (CCT) to discover how nursing faculty teach culture care. The literature revealed that despite 50 years of transcultural nursing knowledge development through theory, research and practice, there remains a lack of formal, integrated culture education in nursing. The importance of faculty providing generic and professional care to nursing students and using an organising framework to teach culture care was discovered. Additionally, care was essential for faculty health and well-being to enable faculty to teach culture care. This unique use of the theory and method demonstrates its usefulness in discovering and describing the complex nature of teaching culture care. Larger scale studies are predicted to further substantiate the CCT, building the discipline of nursing.

Penrose limits, pp waves, and deformed M2-branes

International Nuclear Information System (INIS)

Cvetic, M.; Lue, H.; Pope, C.N.

2004-01-01

Motivated by the recent discussions of the Penrose limit of AdS 5 xS 5 , we examine a more general class of supersymmetric pp-wave solutions of the type IIB theory, with a larger number of nonvanishing structures in the self-dual 5-form. One of the pp-wave solutions can be obtained as a Penrose limit of a D3-D3 intersection. In addition to 16 standard supersymmetries these backgrounds always allow for supernumerary supersymmetries. The latter are in one-to-one correspondence with the linearly realized world-sheet supersymmetries of the corresponding exactly solvable type IIB string action. The pp-waves provide new examples where supersymmetries will survive in a T-duality transformation on the x + coordinate. The T-dual solutions can be lifted to give supersymmetric deformed M2-branes in D=11. The deformed M2-brane is dual to a three-dimensional field theory whose renormalization group flow runs from the conformal fixed point in the infrared regime to a nonconformal theory as the energy increases. At a certain intermediate energy scale there is a phase transition associated with a naked singularity of the M2-brane. In the ultraviolet limit the theory is related by T duality to an exactly solvable massive type IIB string theory

Keeping patients safe in healthcare organizations: a structuration theory of safety culture.

Science.gov (United States)

Groves, Patricia S; Meisenbach, Rebecca J; Scott-Cawiezell, Jill

2011-08-01

This paper presents a discussion of the use of structuration theory to facilitate understanding and improvement of safety culture in healthcare organizations. Patient safety in healthcare organizations is an important problem worldwide. Safety culture has been proposed as a means to keep patients safe. However, lack of appropriate theory limits understanding and improvement of safety culture. The proposed structuration theory of safety culture was based on a critique of available English-language literature, resulting in literature published from 1983 to mid-2009. CINAHL, Communication and Mass Media Complete, ABI/Inform and Google Scholar databases were searched using the following terms: nursing, safety, organizational culture and safety culture. When viewed through the lens of structuration theory, safety culture is a system involving both individual actions and organizational structures. Healthcare organization members, particularly nurses, share these values through communication and enact them in practice, (re)producing an organizational safety culture system that reciprocally constrains and enables the actions of the members in terms of patient safety. This structurational viewpoint illuminates multiple opportunities for safety culture improvement. Nurse leaders should be cognizant of competing value-based culture systems in the organization and attend to nursing agency and all forms of communication when attempting to create or strengthen a safety culture. Applying structuration theory to the concept of safety culture reveals a dynamic system of individual action and organizational structure constraining and enabling safety practice. Nurses are central to the (re)production of this safety culture system. © 2011 Blackwell Publishing Ltd.

Lay theory of race affects and moderates Asian Americans' responses toward American culture.

People may hold different understandings of race that might affect how they respond to the culture of groups deemed to be racially distinct. The present research tests how this process is moderated by the minority individual's lay theory of race. An essentialist lay theory of race (i.e., that race reflects deep-seated, inalterable essence and is indicative of traits and ability) would orient racial minorities to rigidly adhere to their ethnic culture, whereas a social constructionist lay theory of race (i.e., that race is socially constructed, malleable, and arbitrary) would orient racial minorities to identify and cognitively assimilate toward the majority culture. To test these predictions, the authors conducted 4 studies with Asian American participants. The first 2 studies examine the effect of one's lay theory of race on perceived racial differences and identification with American culture. The last 2 studies tested the moderating effect of lay theory of race on identification and assimilation toward the majority American culture after this culture had been primed. The results generally supported the prediction that the social constructionist theory was associated with more perceived similarity between Asians and Americans and more consistent identification and assimilation toward American culture, compared with the essentialist theory.

pp wave big bangs: Matrix strings and shrinking fuzzy spheres

International Nuclear Information System (INIS)

Das, Sumit R.; Michelson, Jeremy

2005-01-01

We find pp wave solutions in string theory with null-like linear dilatons. These provide toy models of big bang cosmologies. We formulate matrix string theory in these backgrounds. Near the big bang 'singularity', the string theory becomes strongly coupled but the Yang-Mills description of the matrix string is weakly coupled. The presence of a second length scale allows us to focus on a specific class of non-Abelian configurations, viz. fuzzy cylinders, for a suitable regime of parameters. We show that, for a class of pp waves, fuzzy cylinders which start out big at early times dynamically shrink into usual strings at sufficiently late times

Evolution, Psychology, and a Conflict Theory of Culture

Directory of Open Access Journals (Sweden)

Kevin MacDonald

2009-04-01

Full Text Available This article develops an evolutionary theory of conflict over the construction of culture that is informed by current knowledge of psychological mechanisms. Psychological mechanisms important for the production of culture include (1 general intelligence (including the ability to engender hypothetical scenarios and means-end reasoning necessary for constructing tools and other exemplars of technology; (2 explicit processing mechanisms (e.g., symbolic representations of the world. Explicit processing allows humans to regulate modular mechanisms in accordance with culturally constructed norms and culturally constructed cost/benefit payoff schedules. It also enables active attempts to construct culture in accordance with explicit perceptions of possible costs and benefits. Because people have different construals of the costs and benefits of particular forms of culture, there is conflict over the construction of culture. Social controls and ideologies are introduced as general cultural categories that are enabled by explicit processing and which are able to regulate and motivate behavior within particular historical contexts, at times in ways that conflict with evolved predispositions. Ideologies are often intimately intertwined with various social controls but are logically and psychologically independent from social controls. Ideologies typically rationalize extant social controls but they also benefit from the power of social controls to enforce ideological conformity in schools or in religious institutions. Because of the control of explicit processing over behavior, this theory predicts that conflicts over culture will often be intense. Discussion deals with the implications of this model for group selection, cultural transmission, gene-culture co-evolution, and the various types of conflicts of interest apparent in conflicts over the construction of culture.

Beyond Authoritarian Personality: The Culture-Inclusive Theory of Chinese Authoritarian Orientation.

Science.gov (United States)

Chien, Chin-Lung

2016-01-01

In a dyad interaction, respecting and obeying those with high status (authority) is highly valued in Chinese societies. Regarding explicit behaviors, Chinese people usually show respect to and obey authority, which we call authoritarian orientation. Previous literature has indicated that Chinese people have a high degree of authoritarian personality, which was considered a national character. However, under Confucian relationalism (Hwang, 2012a), authoritarian orientation is basically an ethical issue, and thus, should not be reduced to the contention of authoritarian personality. Based on Yang's (1993) indigenous conceptualization, Chien (2013) took an emic bottom-up approach to construct an indigenous model of Chinese authoritarian orientation; it represents a "culture-inclusive theory." However, Chien's model lacks the role of agency or intentionality. To resolve this issue and to achieve the epistemological goal of indigenous psychology (that is, "one mind, many mentalities"), this paper took the "cultural system approach" (Hwang, 2015b) to construct a culture-inclusive theory of authoritarian orientation in order to represent the universal mind of human beings as well as the mentalities of people in a particular culture. Two theories that reflect the universal mind, the "Face and Favor model" (Hwang, 1987) and the "Mandala Model of Self" (Hwang, 2011a,c), were used as analytical frameworks for interpreting Chien's original model. The process of constructing the culture-inclusive theory of authoritarian orientation may represent a paradigm for the construction of indigenous culture-inclusive theories while inspiring further development. Some future research directions are proposed herein.

pp and ̄pp elastic scattering

Directory of Open Access Journals (Sweden)

A. Donnachie

1984-01-01

Full Text Available We present an analysis of pp and ̄pp elastic scattering in terms of various exchanges. Three-gluon exchange dominates at large t, and single-pomeron exchange at small t. The dip seen in high-energy pp scattering is provided by the interference of both of these with double-pomeron exchange. We predict that this dip will not be found in high-energy ̄pp scattering. The dip that is seen in low-energy ̄pp scattering is the result of the additional presence of reggeon-pomeron exchange.

In this paper, we introduce Gilles Fauconnier & Mark Turner's blending theory as a new conceptual framework for explaining ‘cultural frame shifting' in interaction design. Cultural frame shifting is when people, through their explorative use of technology, are required imaginatively to reorganize...... their cultural background knowledge and expectations. In current HCI research it has occasionally been pointed out that a proper understanding of this phenomenon hinges on addressing the relationship between embodied interaction and cultural meaning construction as part of a larger interactive system. However...... the network model of mental spaces from Fauconnier & Turner's blending theory onto video material and interviews from initial qualitative use studies of a design case.

Affordances and Landscapes: Overcoming the Nature-Culture Dichotomy through Niche Construction Theory.

Science.gov (United States)

Heras-Escribano, Manuel; De Pinedo-García, Manuel

2017-01-01

In this paper we reject the nature-culture dichotomy by means of the idea of affordance or possibility for action, which has important implications for landscape theory. Our hypothesis is that, just as the idea of affordance can serve to overcome the subjective-objective dichotomy, the ideas of landscape and ecological niche, properly defined, would allow us to also transcend the nature-culture dichotomy. First, we introduce an overview of landscape theory, emphasizing processual landscape theory as the most suitable approach for satisfying both cultural and naturalist approaches. After that, we introduce the idea of affordance and we analyze a tension between sociocultural and transcultural affordances (affordances that depend on cultural conventions and affordances that depend on lawful information and bodily aspects of agents). This tension has various implications for landscape theory and ecological niches. Our proposal is that sociocultural and transcultural aspects of affordances could be systematically accommodated if we apply niche construction theory (the theory that explains the process by which organisms modify their selective environments) as a methodological framework for explaining the emergence of ecological niches. This approach will lead us to an integrative account of landscapes as the products of the interaction between human and environmental elements, making it a clear example of a concept that transcends the nature-culture dichotomy.

Cultural diversity, democracy and the prospects of cosmopolitanism: a theory of cultural encounters.

Science.gov (United States)

Delanty, Gerard

2011-12-01

The most appropriate way of theorizing cultural diversity is to situate it in the context of a broader relational theory of culture in which the key dynamic is cultural encounters. The relational conception of culture places the emphasis on the relations between social actors and the processes by which some of these relations generate enduring cultural regularities and forms. This has important implications for political community and in particular for cosmopolitanism. It is in relationships that cultural phenomena are generated and become the basis of different kinds of political community. The paper outlines a typology of six kinds of cultural encounters and discusses four major cultural trends that variously emerge from these encounters. This approach with its emphasis on cultural encounters is the broad sociological context in which questions about cultural change and the prospects of cosmopolitanism should be discussed. © London School of Economics and Political Science 2011.

Biomechanical stimuli play important roles in the formation of articular cartilage during early foetal life, and optimal mechanical load is a crucial regulatory factor of adult chondrocyte metabolism and function. In this study, we undertook to analyse mechanotransduction pathways during in vitro chondrogenesis. Chondroprogenitor cells isolated from limb buds of 4-day-old chicken embryos were cultivated as high density cell cultures for 6 days. Mechanical stimulation was carried out by a self-designed bioreactor that exerted uniaxial intermittent cyclic load transmitted by the culture medium as hydrostatic pressure and fluid shear to differentiating cells. The loading scheme (0.05 Hz, 600 Pa; for 30 min) was applied on culturing days 2 and 3, when final commitment and differentiation of chondroprogenitor cells occurred in this model. The applied mechanical load significantly augmented cartilage matrix production and elevated mRNA expression of several cartilage matrix constituents, including collagen type II and aggrecan core protein, as well as matrix-producing hyaluronan synthases through enhanced expression, phosphorylation and nuclear signals of the main chondrogenic transcription factor Sox9. Along with increased cAMP levels, a significantly enhanced protein kinase A (PKA) activity was also detected and CREB, the archetypal downstream transcription factor of PKA signalling, exhibited elevated phosphorylation levels and stronger nuclear signals in response to mechanical stimuli. All the above effects were diminished by the PKA-inhibitor H89. Inhibition of the PKA-independent cAMP-mediators Epac1 and Epac2 with HJC0197 resulted in enhanced cartilage formation, which was additive to that of the mechanical stimulation, implying that the chondrogenesis-promoting effect of mechanical load was independent of Epac. At the same time, PP2A activity was reduced following mechanical load and treatments with the PP2A-inhibitor okadaic acid were able to mimic the effects of

A renormalization group theory of cultural evolution

Fáth, Gábor; Sarvary, Miklos

2005-03-01

We present a theory of cultural evolution based upon a renormalization group scheme. We consider rational but cognitively limited agents who optimize their decision-making process by iteratively updating and refining the mental representation of their natural and social environment. These representations are built around the most important degrees of freedom of their world. Cultural coherence among agents is defined as the overlap of mental representations and is characterized using an adequate order parameter. As the importance of social interactions increases or agents become more intelligent, we observe and quantify a series of dynamic phase transitions by which cultural coherence advances in the society. A similar phase transition may explain the so-called “cultural explosion’’ in human evolution some 50,000 years ago.

Sexuality and psychoanalytic aggrandisement: Freud's 1908 theory of cultural history.

Science.gov (United States)

Cotti, Patricia

2011-03-01

In 1908, in his article "'Civilized" sexual morality and modern nervous illness', Freud presented neuroses as the consequence of a restrictive state of cultural development and its 'civilized morality'. He found the inspiration for this idea by expanding upon previous formulations in this area by his predecessors (notably Christian von Ehrenfels) that focused on a cultural process earlier introduced by Kant, while also integrating in his analysis the principles of Haeckel's evolutionism (history of development, recapitulation) which eventually re-defined the psychoanalytic theory of neuroses. These new theoretical elements became the basis of psychoanalytic theory and thereby influenced subsequent thinking in the cultural process itself and in human sciences. This transformation of underlying theory provided a unique historical and analytical framework for psychoanalysis which allowed Freud to claim for it a pre-eminent position among the human sciences.

Moving Beyond Conventional Wisdom: Advancements in Cross-Cultural Theories of Leadership, Conflict, and Teams.

Gibson, Cristina B; McDaniel, Dana M

2010-07-01

In this article, we discuss the importance of a cross-cultural approach to organizational behavior. To do so, we illustrate how cross-cultural research in the past two decades has enabled us to reconceptualize constructs, revise models, and extend boundary conditions in traditional organizational behavior theories. We focus on three domains-teams, leadership, and conflict-and review cross-cultural empirical evidence that has extended several theories in each of these domains. We support the claim that even well-established organizational behavior theories vary in the extent to which they may be applied unilaterally across cultures, thus identifying the critical need to advance these theories via a cross-cultural research agenda. © The Author(s) 2010.

Study of pp{yields}pp{eta} reaction at threshold; Etude de la reaction pp{yields}pp{eta} au seuil

Energy Technology Data Exchange (ETDEWEB)

Taleb, A

1994-11-01

The {eta} production has been studied through the pp {yields} pp{eta} reaction at threshold. Data were taken at the Synchrotron of the ``Laboratoire National Saturne``. The detection in coincidence of the two protons scattered near 0 deg and analysed with the magnetic spectrometer SPES3 allows the reconstruction of missing mass spectra for the {eta} signature. A simulation program which takes into account all the experimental set up characteristics has been realized and tested through the pp {yields} d{pi}{sup +} reaction detected simultaneously with pp {yields} pp{eta}. The generated proton momentum spectra for pp {yields} pp{eta} show a pronounced {eta} mass dependence. This characteristic, connected to the kinematical properties of pp {yields} pp{eta} at threshold, is used to extract the mass of the meson {eta}. The obtained value, m{sub {eta}} = 547.65 {+-} 0.18 MeV, is in good agreement with measurement done recently through the pd {yields} {sup H}e{eta} reaction. The total cross section {sigma}{sub t} of pp {yields} pp{eta} measured at 1260, 1265 and 1300 MeV presents a strong energy dependence. This cross section increases less with energy than the phase-space. The influence of p-p and {eta}-p final state interactions in our measurements is studied. Our results are compared with theoretical predictions and assess the dominant character of the baryonic resonance N{sup *}(1535) in the {eta} mechanism production at threshold. These experimental results give an energy dependence which is not well reproduced by the theoretical predictions. This discrepancy could be an incorrect description of the {eta}-p interaction in the models. (author). 48 refs., 60 figs., 15 tabs.

Personality maturation around the world: a cross-cultural examination of social-investment theory.

Science.gov (United States)

Bleidorn, Wiebke; Klimstra, Theo A; Denissen, Jaap J A; Rentfrow, Peter J; Potter, Jeff; Gosling, Samuel D

During early adulthood, individuals from different cultures across the world tend to become more agreeable, more conscientious, and less neurotic. Two leading theories offer different explanations for these pervasive age trends: Five-factor theory proposes that personality maturation is largely determined by genetic factors, whereas social-investment theory proposes that personality maturation in early adulthood is largely the result of normative life transitions to adult roles. In the research reported here, we conducted the first systematic cross-cultural test of these theories using data from a large Internet-based sample of young adults from 62 nations (N = 884,328). We found strong evidence for universal personality maturation from early to middle adulthood, yet there were significant cultural differences in age effects on personality traits. Consistent with social-investment theory, results showed that cultures with an earlier onset of adult-role responsibilities were marked by earlier personality maturation.

Culture care theory: a framework for expanding awareness of diversity and racism in nursing education.

Science.gov (United States)

Lancellotti, Katherine

2008-01-01

As American society becomes increasingly diverse, and the nursing profession does not, there has been a focus on promoting both cultural competence and diversity within the profession. Although culture and diversity are widely discussed in nursing education, the issue of racism may be avoided or suppressed. Institutionalized racism within nursing education must be acknowledged and discussed before nursing education may be transformed. Madeleine Leininger's Culture Care Theory is an established nursing theory that emphasizes culture and care as essential concepts in nursing. Theoretical frameworks abound in nursing, and Culture Care Theory may be underutilized and misunderstood within nursing education. This article examines the issue of racism in nursing education and recommends Culture Care Theory as a relevant framework for enhancing both cultural competence and diversity.

Penrose limit, spontaneous symmetry breaking, and holography in a pp-wave background

International Nuclear Information System (INIS)

Das, Sumit R.; Gomez, Cesar; Rey, Soo-Jong

2002-01-01

We argue that the gauge theory dual to the type IIB string theory in a ten-dimensional pp-wave background resides on a Euclidean subspace spanning four of the eight transverse coordinates. We then show that the evolution of the string along one of the light cone directions in the bulk is identifiable as the RG flow of the gauge theory, a relation facilitating the 'holography' of the pp-wave background. The 'holography' reorganizes the dual gauge theory into theories defined over Hilbert subspaces of fixed R charge. The reorganization breaks the SO(4,2)xSO(6) symmetry to a maximal subgroup SO(4)xSO(4) spontaneously. We argue that the low-energy string modes may be regarded as Goldstone modes resulting from such a symmetry breaking pattern

Culture care theory: a major contribution to advance transcultural nursing knowledge and practices.

Science.gov (United States)

Leininger, Madeleine

2002-07-01

This article is focused on the major features of the Culture Care Diversity and Universality theory as a central contributing theory to advance transcultural nursing knowledge and to use the findings in teaching, research, practice, and consultation. It remains one of the oldest, most holistic, and most comprehensive theories to generate knowledge of diverse and similar cultures worldwide. The theory has been a powerful means to discover largely unknown knowledge in nursing and the health fields. It provides a new mode to assure culturally competent, safe, and congruent transcultural nursing care. The purpose, goal, assumptive premises, ethnonursing research method, criteria, and some findings are highlighted.

Culture Care Theory: a proposed practice theory guide for nurse practitioners in primary care settings.

Science.gov (United States)

McFarland, Marilyn M; Eipperle, Marilyn K

2008-04-01

Leininger's Theory of Culture Care Diversity and Universality is presented as a foundational basis for the educational preparation, primary care contextual practice, and outcomes-focused research endeavours of advanced practice nursing. Discussion emphasises the value of care and caring as the essence of advanced practice nursing through the use of three modes of care, use of the Sunrise and other enablers, and the ethnonursing method. Education, research, practice, and key concepts of the theory are connected as essential components toward the provision of culturally congruent care to meet the healthcare needs of diverse individuals, families, groups, and communities by family nurse practitioners.

The effects of PMMA and PP-g-PMMA on the oxidation of polypropylene (PP) have been studied. The mixing was done in Laboplastomill at the temperature of 200 o C, and screw speed of 20 rpm, for 5 minutes. The PMMA concentrations were 1, 2, 5, and 10% by weight, and PP-g-PMMA (12% grafting) 5, 10, and 20% by weight. Mechanical properties (tensile strength (Tb) and elongation at break (Eb)( of the mixture decreased with the increase of PMMA content over 5%. The addition of PMMA over 3% produced non-transparent film. Electron beam irradiation at the dose of 5, 10, 30, and 50 kGy was carried out to accelerate the matrix oxidation is accelerated. The optimum properties of PP/PMMA blends can be achieved by addition of maximum 2% PMMA either direct as PMMA or as compatibilizer (PP-g-PMMA). (authors)

New Institutional Theory and a Culture of Safety in Agriculture.

Science.gov (United States)

Janssen, Brandi; Nonnenmann, Matthew W

2017-01-01

Health and safety professionals often call for an improved safety culture in agriculture. Such a shift would result in agricultural practices that prioritize safe work habits and see safety as both an effective means to improve production and a goal worth pursuing in its own right. This article takes an anthropological approach and demonstrates the potential for new institutional theory to conceptualize broader cultural change in agriculture. New institutional theory examines the roles of organizations and the ways that they inform and support broad social institutions. Using preliminary data from the agricultural lending industry in Iowa and integrated poultry production in Texas, this article considers the ability of these organizations to contribute to systemic change and an improved culture of safety in agriculture.

Surface/state correspondence and bulk local operators in pp-wave holography

Directory of Open Access Journals (Sweden)

Nakwoo Kim

2015-12-01

Full Text Available We apply the surface/state correspondence proposal of Miyaji et al. to IIB pp-waves and propose that the bulk local operators should be instantonic D-branes. In line with ordinary AdS/CFT correspondence, the bulk local operators in pp-waves also create a hole, or a boundary, in the dual gauge theory as pointed out by H. Verlinde, and by Y. Nakayama and H. Ooguri. We also present simple calculations which illustrate how to extract the spacetime metric of pp-waves from instantonic D-branes in boundary state formalism.

Cultural theory and risk perception: validity and utility explored in the French context

International Nuclear Information System (INIS)

Brenot, J.; Bonnefous, S.; Mays, C.

1996-01-01

Explaining perceived risk can draw upon factors related to the person (e.g. demographics, personality, social/professional status, political orientation), or to the risk source (e.g. health impacts, economic effects). According to Cultural Theory risk perceptions are culturally biased. Wildavsky and Dake operationalised the Cultural Theory with questionnaire scales and found that resulting 'cultural profiles' best predict individual differences in risk perception. A French version of their questionnaire was inserted into a representative national risk opinion survey of May 1993; 1022 adults (age 18 and over) were interviewed. Major results are presented. The four cultural scales (hierarchy, egalitarianism, fatalism and individualism) show high correlations with political orientation as expected, but also with, for example, age, gender, income and education level. However, scale relationships to perception of risk situations (twenty, mainly technological) are not as strong as expected. Sjoeberg found similar results in Sweden. The utility of the existing operationalisation of Cultural Theory for risk perception analysis is discussed. (author)

Studies using in vitro cultured oocytes have indicated that the protein phosphatase 2A (PP2A), a major serine/threonine protein phosphatase, participates in multiple steps of meiosis. Details of oocyte maturation regulation by PP2A remain unclear and an in vivo model can provide more convincing information. Here, we inactivated PP2A by mutating genes encoding for its catalytic subunits (PP2Acs) in mouse oocytes. We found that eliminating both PP2Acs caused female infertility. Oocytes lacking PP2Acs failed to complete 1(st) meiotic division due to chromosome misalignment and abnormal spindle assembly. In mitosis, PP2A counteracts Aurora kinase B/C (AurkB/C) to facilitate correct kinetochore-microtubule (KT-MT) attachment. In meiosis I in oocyte, we found that PP2Ac deficiency destabilized KT-MT attachments. Chemical inhibition of AurkB/C in PP2Ac-null oocytes partly restored the formation of lateral/merotelic KT-MT attachments but not correct KT-MT attachments. Taken together, our findings demonstrate that PP2Acs are essential for chromosome alignments and regulate the formation of correct KT-MT attachments in meiosis I in oocytes.

Does Parental Mind-Mindedness Account for Cross-Cultural Differences in Preschoolers' Theory of Mind?

This study of 241 parent-child dyads from the United Kingdom (N = 120, M age  = 3.92, SD = 0.53) and Hong Kong (N = 121, M age  = 3.99, SD = 0.50) breaks new ground by adopting a cross-cultural approach to investigate children's theory of mind and parental mind-mindedness. Relative to the Hong Kong sample, U.K. children showed superior theory-of-mind performance and U.K. parents showed greater levels of mind-mindedness. Within both cultures parental mind-mindedness was correlated with theory of mind. Mind-mindedness also accounted for cultural differences in preschoolers' theory of mind. We argue that children's family environments might shed light on how culture shapes children's theory of mind. © 2017 The Authors.

Homelessness as culture: How transcultural nursing theory can assist caring for the homeless.

Science.gov (United States)

Law, Kate; John, William

2012-11-01

The concepts of culture and homelessness are both complex and contested. This paper examines homelessness through the lens of transcultural nursing theory, increasing understanding of both homelessness and transcultural theory. We argue that homelessness can be usefully conceptualised as a culture and that the application of transcultural theory to caring for homeless people will add further to the utility of these theories. The application of transcultural theory can add to the repertoire of skills the nurse needs to care for not only homeless clients, but, for a diverse range of client groups.

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

Directory of Open Access Journals (Sweden)

Chi-Ming Hsieh

2017-05-01

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

Superstring interactions in a pp-wave background II

International Nuclear Information System (INIS)

Spradlin, Marcus; Volovich, Anastasia

2003-01-01

In type-IIB light-cone superstring field theory, the cubic interaction has two pieces: a delta-functional overlap and an operator inserted at the interaction point. In this paper we extend our earlier work by computing the matrix elements of this operator in the oscillator basis of pp-wave string theory for all μ p +α '. By evaluating these matrix elements for large μ p +α ', we check a recent conjecture relating matrix elements of the light-cone string field theory hamiltonian (with prefactor) to certain three-point functions of BMN operators in the gauge theory. We also make several predictions for gauge theory. (author)

Dialogue, Eurocentrism, and Comparative Political Theory: A View from Cross-Cultural Intellectual History.

Science.gov (United States)

Shogimen, Takashi

2016-01-01

Comparative political theory is an emerging sub-field of political theory; it is a response to the dissatisfaction with the prevalent Eurocentric mode of political theorizing in the age of globalization. A methodological characteristic of comparative political theory is cross-cultural engagement through dialogue with foreign political ideas. The present paper argues that the dialogical mode of cross-cultural engagement is distinctively European. While the dialogical engagement with foreign worldviews constitutes a mainstream of the European literary tradition, it is largely absent, for example, from the Japanese counterpart. Despite its anti-Eurocentric motivations, comparative political theory is methodologically rooted in the European tradition.

High energy elastic pp differential cross section at LHC at the c.m. energy 14 TeV is predicted using the asymptotic behavior of sigma-tot(s) and rho(s), and the measured pbar-p differential cross section at sqrt{s}=546 GeV. The phenomenological investigation has progressively led to an effective field theory model that describes the nucleon as a chiral bag embedded in a quark-antiquark condensed ground state. The measurement of pp elastic scattering at LHC up to large |t| >~ 10 GeV^2 by the TOTEM group will be crucial to test this structure of the nucleon.

Full Text Available  ABSTRACTThis article presents a theoretical analysis and discussion of the theory of gerotranscendence, formulatedby Lars Tornstam (University of Uppsala, Sweden. The theory is presented as a meta-theory ofageing, as a theory of universal and general ageing processes. Ageing is seen as an urge (a drivetowards a less engaged posititon in the wordly life, moving towards a higher degree of transcendence,with a more cosmic outlook and another definition of reality. In this article the theory is discussed fromanother theoretical position; Ageing seen in a cultural gerontological perspective, as a varied culturallyand historically situated phenomenon – differing in different times and different cultures. The theoreticalperspective underlines that ageing is complex dialectical processes, an intertwined interplay betweenindividual development and cultural change. The varied individual ageing processes are not seenas the result of «drives». In Western post-modern cultures the ageing processes are becoming manifold,often contradictory.

Supersymmetric backgrounds in string and M-theory of the Gödel Universe type are studied. We find several new Gödel Universes that preserve up to 20 supersymmetries. In particular, we obtain an interesting Gödel Universe in M-theory with 18 supersymmetries which does not seem to be dual to a pp......-wave. We show that not only T-duality but also the type-IIA/M-theory S-duality can give supersymmetric Gödel Universes from pp-waves. We find solutions that can interpolate between Gödel Universes and pp-waves. We also compute the string spectrum on two type IIA Gödel Universes. Furthermore, we obtain...

Similarities and differences between antipp and pp scattering at TeV energies and beyond

International Nuclear Information System (INIS)

Gauron, P.; Nicolescu, B.

1986-12-01

The significant difference between the pp and antipp elastic dσ/dt discovered at the CERN ISR, and the behaviour of the antipp dσ/dt at the CERN collider, which have profound implications for the asymptotic behaviour of hadron scattering amplitudes, are explained in terms of a model theory based upon general S-matrix principles and a dynamical assumption of ''maximal strength'' for the strong interactions. Our model theory provides an excellent description of the pp and antipp data in the huge range 10 ≤ √s ≤ 630 GeV for /t/ ≤2.5 (GeV) 2 . Several striking consequences of the theory will be testable at Tevatron energies and beyond

Community transformation through culturally competent nursing leadership: application of theory of culture care diversity and universality and tri-dimensional leader effectiveness model.

Science.gov (United States)

Shapiro, Mina L; Miller, June; White, Kathleen

2006-04-01

Transcultural knowledge and competency have become a critical need for nurses to accommodate the global trends in cultural diversity and health care disparities. Today, nurses are increasingly taking on leadership roles in community settings. This article addresses the application of Leininger's culture care theory with the sunrise model and Hersey and Blanchard's tri-dimensional leader effectiveness model as potential collaborating theories for capacity building and community transformation from a global, transcultural nursing perspective. The two theories, used in collaboration, view the provision of competent leadership as the delivery of effective, culturally congruent nursing care in promoting health and health equity at the community level.

Full Text Available The work aims to study the theory of translation of Boaventura de Sousa Santos and its application in crop protection. As well as examining the case of Community biocultural protocols in Colombia in search for alternative protection for traditional knowledge. The questions in this study were performed: A Theory of Translation Boaventura de Sousa Santos could be a condition of possibility for the protection of culture and traditional knowledge? And the biocultural community protocols could be an example of the theory of translation? To answer these research questions we used the combination of two methods: deductive and monographic. The first was used to guide the documentary and doctrinal research as it relates to globalization and culture. The monographic method was used for the second part, to address the translation theory of Boaventura de Sousa Santos and the case of bio-cultural Community Protocols in Colombia.

Cultural care of older Greek Canadian widows within Leininger's theory of culture care.

Science.gov (United States)

Rosenbaum, J N

1990-01-01

Cultural care themes were abstracted from a large scale study of older Greek Canadian widows conceptualized within Leininger's theory of Cultural Care Diversity and Universality. Ethnonursing, ethnographic, and life health-care history methods were used. Data were collected using observation-participation and interviews in three Greek Canadian communities with 12 widowed key informants and 30 general informants. Enabling tools used were interview inquiry guides, Leininger's Life History Health Care Protocol, Leininger's Acculturation Rating and Profile Scale of Traditional and Non-Traditional Lifeways, and field journal recordings. Data were analyzed using Leininger's phases of analysis for qualitative data. The two major cultural care themes which were abstracted from the raw data and patterns were: (1) Cultural care for Greek Canadian widows meant responsibility for, reciprocation, concern, love, companionship, family protection, hospitality, and helping, primarily derived from their kinship, religious, and cultural beliefs, and values, and (2) Cultural care continuity diminished the spousal care void and contributed to the health of Greek Canadian widows. These findings will stimulate future nursing research related to cultural care of diverse populations and guide nursing practice to provide culturally congruent care which will assist widows to reduce their spousal care void. The author thanks Dr. Madeleine Leininger, Dr. Judith Floyd, Dr. Marjorie Isenberg, and Dr. Bernice Kaplan for their guidance in completing the large scale study on which this article is based.

High theory/mass markets: Newsweek magazine and the circuits of medical culture.

Science.gov (United States)

Lewis, Bradley

2007-01-01

Medicine is driven by much more than science and reason (ethics); it is also driven by the circuits of culture within which it operates. This article examines how postmodern theory deconstructs standard ideals of science and reason and allows medical humanities scholars to better contextualize the world of medicine. As such, postmodern theory provides an invaluable tool for understanding the circuits of popular culture and medicine's place within these circuits. Using a recent issue of Newsweek magazine devoted to health and technology to illustrate the main points, this essay argues that contemporary popular influences on medicine are deeply problematic, and that through an appreciation of the dynamics of culture, medical humanities scholars can join the struggle over medical culture. This perspective allows medical humanities to make important contributions toward alternative circuits of medical representation, consumption, and identification.

First-person perspective effects on theory of mind without self-reference.

Directory of Open Access Journals (Sweden)

Yuki Otsuka

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

Children’s Self-Regulation in Cultural Contexts: The Role of Parental Socialization Theories, Goals, and Practices

Science.gov (United States)

Jaramillo, Jorge M.; Rendón, María I.; Muñoz, Lorena; Weis, Mirjam; Trommsdorff, Gisela

2017-01-01

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

Mustafa Akın Güngör

2011-06-01

Full Text Available Since it is quite difficult in traditional learning atmospheres for the learners to be exposed to the target language adequately in foreign language acquisition, CALL in which virtual environment is designed in more appropriate way has given rise. Two main paradigms, cognitive model and socio-cultural theory, have also been adopted in CALL. Moreover, rather than applying one theory, combination of these paradigms is unavoidable. However, application of this combination is challenging in practice, as these two theories have different principles. Furthermore, when it comes to online education, it turns into more challenging process. In this poster this combination is presented with the help of sample applications from Gazi University.

Testing the cultural theory of risk in France

International Nuclear Information System (INIS)

Brenot, J.; Bonnefous, S.; Marris, C.

1998-01-01

Cultural Theory, as developed by Mary Douglas, argues that differing risk perceptions can be explained by reference to four distinct cultural biases: hierarchy, egalitarianism, individualism, and fatalism. This paper presents empirical results from a quantitative survey based on a questionnaire devised by Karl Dake to measure these cultural biases. A large representative sample was used to test this instrument in the French social context. Correlations between cultural biases and perceptions of 20 social and environmental risks were examined. These correlations were very weak, but were statistically significant: cultural biases explained 6%, at most, of the variance in risk perceptions. Standard socio-demographic variables were also weakly related to risk perceptions (especially gender, social class, and education), and cultural biases and socio-demographic variables were themselves intercorrelated (especially with age, social class, and political outlook). The authors compare these results with surveys conducted in other countries using the same instrument and conclude that new methods, more qualitative and contextual, still need to be developed to investigate the cultural dimensions of risk perceptions. The paper also discusses relationships between perceptions of personal and residual risk, and between perceived risk and demand for additional safety measures. These three dimensions were generally closely related, but interesting differences were observed for some risk issues. Included in the list of risk perceptions were pollution, hazardous materials, and radioactive wastes

Predictions for PP-wave string amplitudes from perturbative SYM

Gursoy, Umut

2003-01-01

The role of general two-impurity multi-trace operators in the BMN correspondence is explored. Surprisingly, the anomalous dimensions of all two-impurity multi-trace BMN operators to order g 2 2 λ' are completely determined in terms of single-trace anomalous dimensions. This is due to suppression of connected field theory diagrams in the BMN limit and this fact has important implications for some string theory processes on the PP-wave background. We also make gauge theory predictions for the matrix elements of the light-cone string field theory Hamiltonian in the two string-two string and one string-three string sectors. (author)

In Search of a Theory: The Interpretative Challenge of Empirical Findings on Cultural Variance in Mindreading

Directory of Open Access Journals (Sweden)

Gut Arkadiusz

2016-12-01

Full Text Available In this paper, we present a battery of empirical findings on the relationship between cultural context and theory of mind that show great variance in the onset and character of mindreading in different cultures; discuss problems that those findings cause for the largely-nativistic outlook on mindreading dominating in the literature; and point to an alternative framework that appears to better accommodate the evident cross-cultural variance in mindreading. We first outline the theoretical frameworks that dominate in mindreading research, then present the relevant empirical findings, and finally we come back to the theoretical approaches in a discussion of their explanatory potential in the face of the data presented. The theoretical frameworks discussed are the two-systems approach; performance-based approach also known as modularity-nativist approach; and the social-communicative theory also known as the systems, relational-systems, dynamic systems and developmental systems theory. The former two, which both fall within the wider modular-computational paradigm, run into a challenge with the cross-cultural data presented, and the latter - the systemic framework - seems to offer an explanatorily potent alternative. The empirical data cited in this paper comes from research on cross-cultural differences in folk psychology and theory-of-mind development; the influence of parenting practices on the development of theory of mind; the development and character of theory of mind in deaf populations; and neuroimaging research of cultural differences in mindreading.

Innovative practice: exploring acculturation theory to advance rehabilitation from pediatric to adult "cultures" of care.

Science.gov (United States)

Nguyen, Tram; Baptiste, Sue

2015-01-01

This perspective paper explores the application of acculturation and the inherent concepts and ideas associated with this theory in rehabilitation to provide a framework for interpreting patient circumstances, responses and behaviours as they move from one culture to the next. Traditionally acculturation theory has been use to examine changes in culture in an ethnic or country sense, however, this paper is among the first to apply acculturation theory to the rehabilitation service cultures from pediatric to adult care for youth with chronic health conditions. The objectives of this paper are threefold: (1) to critically appraise key literature in the development of acculturation theory, (2) to discuss how acculturation theory can be applied in rehabilitation practice through a clinical vignette, and finally (3) to discuss how acculturation theory can advance rehabilitation by enhancing client-centered practice. Acculturation theory can provide insight into how patients are experiencing a change in health care "cultures", in the context of their overarching life circumstances. This, coming from a broader societal perspective can in turn inform an optimal approach to client-centered practice, and the application of rehabilitation-specific team inputs. This theoretical framework can heighten practitioners' awareness of patients' unique worldviews related to their expectations for care and treatment thus reducing fear of diversity to establish positive partnerships between patients and clinicians. An understanding of patients' acculturation processes will add new insight into how we can best deliver services and supports to optimise health, opportunities and experiences for youth with chronic conditions.

Synthesis strategy: building a culturally sensitive mid-range theory of risk perception using literary, quantitative, and qualitative methods.

Science.gov (United States)

Siaki, Leilani A; Loescher, Lois J; Trego, Lori L

2013-03-01

This article presents a discussion of development of a mid-range theory of risk perception. Unhealthy behaviours contribute to the development of health inequalities worldwide. The link between perceived risk and successful health behaviour change is inconclusive, particularly in vulnerable populations. This may be attributed to inattention to culture. The synthesis strategy of theory building guided the process using three methods: (1) a systematic review of literature published between 2000-2011 targeting perceived risk in vulnerable populations; (2) qualitative and (3) quantitative data from a study of Samoan Pacific Islanders at high risk of cardiovascular disease and diabetes. Main concepts of this theory include risk attention, appraisal processes, cognition, and affect. Overarching these concepts is health-world view: cultural ways of knowing, beliefs, values, images, and ideas. This theory proposes the following: (1) risk attention varies based on knowledge of the health risk in the context of health-world views; (2) risk appraisals are influenced by affect, health-world views, cultural customs, and protocols that intersect with the health risk; (3) strength of cultural beliefs, values, and images (cultural identity) mediate risk attention and risk appraisal influencing the likelihood that persons will engage in health-promoting behaviours that may contradict cultural customs/protocols. Interventions guided by a culturally sensitive mid-range theory may improve behaviour-related health inequalities in vulnerable populations. The synthesis strategy is an intensive process for developing a culturally sensitive mid-range theory. Testing of the theory will ascertain its usefulness for reducing health inequalities in vulnerable groups. © 2012 Blackwell Publishing Ltd.

Progesterone-associated proteins PP12 and PP14 in the human endometrium.

Science.gov (United States)

Rutanen, E M; Koistinen, R; Seppälä, M; Julkunen, M; Suikkari, A M; Huhtala, M L

1987-01-01

Two proteins, designated as PP12 and PP14 were originally isolated from soluble extracts of the human placenta and its adjacent membranes. We have shown that they are synthesized by decidualized/secretory endometrium and not by placenta. Both proteins occur at high concentrations in human amniotic fluid, which is therefore an excellent source for purification. PP12 is a 34-kDa glycoprotein, which has an N-terminal amino acid sequence of Ala-Pro-Trp-Gln-Cys-Ala-Pro-Cys-Ser-Ala. This is identical with that of somatomedin-binding protein purified from the amniotic fluid. PP12 too binds somatomedin-C, or IGF-I (insulin-like growth factor-I). Human secretory endometrium synthesizes and secretes PP12, and progesterone stimulates its secretion. PP14 is a 28-kDa glycoprotein. Its N-terminal sequence shows homology to that of beta-lactoglobulins from various species. We have found PP14 in the human endometrium, serum and milk. Immunologically, PP14 is related to progestagen-associated endometrial protein (PEP), alpha-2 pregnancy-associated endometrial protein (alpha-2, PEG), endometrial protein 15 (EP15), alpha-uterine protein (AUP) and chorionic alpha-2 microglobulin (CAG-2). In ovulatory menstrual cycles, the concentration of PP14 increases in endometrial tissue as the secretory changes advance. In serum, the PP14 concentration begins to rise later than the progesterone levels, and high serum PP14 levels are maintained for the first days of the next cycle. By contrast, no elevation of serum PP14 level is seen in anovulatory cycles. Our results show that progesterone-associated proteins are synthesized by the human endometrium and appear in the peripheral circulation, where they can be quantitatively measured using immunochemical techniques.

Distributed communication: Implications of cultural-historical activity theory (CHAT) for communication disorders.

Science.gov (United States)

Hengst, Julie A

2015-01-01

This article proposes distributed communication as a promising theoretical framework for building supportive environments for child language development. Distributed communication is grounded in an emerging intersection of cultural-historical activity theory (CHAT) and theories of communicative practices that argue for integrating accounts of language, cognition and culture. The article first defines and illustrates through selected research articles, three key principles of distributed communication: (a) language and all communicative resources are inextricably embedded in activity; (b) successful communication depends on common ground built up through short- and long-term histories of participation in activities; and (c) language cannot act alone, but is always orchestrated with other communicative resources. It then illustrates how these principles are fully integrated in everyday interactions by drawing from my research on Cindy Magic, a verbal make-believe game played by a father and his two daughters. Overall, the research presented here points to the remarkably complex communicative environments and sophisticated forms of distributed communication children routinely engage in as they interact with peer and adult communication partners in everyday settings. The article concludes by considering implications of these theories for, and examples of, distributed communication relevant to clinical intervention. Readers will learn about (1) distributed communication as a conceptual tool grounded in an emerging intersection of cultural-historical activity theory and theories of communicative practices and (2) how to apply distributed communication to the study of child language development and to interventions for children with communication disorders.

General definition of the concept of "sport" as one of the basic constructs of the general theory of physical culture and sports theory

Directory of Open Access Journals (Sweden)

Vasil Sutula

2018-02-01

Full Text Available Purpose: to reveal modern ideas about the essence of the concept of "sport" and determine its role in the development of the general theory of physical culture and sports theory. Material & Methods: analysis of specialized literature, which highlights various aspects of the development of the field of people's activities related to the use of physical exercises. Results: in today's society there is an objective sphere of human activity related to the use of physical exercises, for which the name in domestic and foreign scientific and social practice is most often used the term "physical culture". Conclusion: the constitutive conditions of the process of developing a general theory of physical culture are singled out, it is shown that sport, as a special socio-cultural phenomenon, is a historically conditioned activity of people associated with the use of physical exercises, aimed at preparing and participating in competitions, as well as individual and socially significant results of such activity.

Charm baryon production in pp and p-Pb collisions with ALICE

CERN Multimedia

CERN. Geneva

2018-01-01

The measurement of inclusive open heavy-flavour production in pp collisions is an important test of perturbative QCD calculations, and also offers a direct way to study non-perturbative QCD processes. Charmed baryon production measurements, in particular, are useful to address the hadronisation of charm quarks. Measurements in pp and p-Pb collisions also provide a baseline for Pb-Pb collisions, where the baryon-to-meson ratios will offer a unique probe of charm thermalisation and hadronisation mechanisms in the Quark-Gluon Plasma. The production of D0, D+, D*+ and Ds mesons has been measured with ALICE in pp collisions at the LHC at several collision energies, and was found to be compatible with expectations from theory. In this talk, recent measurements of Λc+ and Ξc0 baryon production in pp collisions at a centre-of-mass energy of 7 TeV and Λc+ baryon production in p-Pb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV will be presented.

PP2A contributes to endothelial death in high glucose: inhibition by benfotiamine.

Science.gov (United States)

Du, Y; Kowluru, A; Kern, T S

2010-12-01

Endothelial death is critical in diabetic vascular diseases, but regulating factors have been only partially elucidated. Phosphatases play important regulatory roles in cell metabolism, but have not previously been implicated in hyperglycemia-induced cell death. We investigated the role of the phosphatase, type 2A protein phosphatase (PP2A), in hyperglycemia-induced changes in signaling and death in bovine aortic endothelial cells (BAEC). We explored also the influence of benfotiamine on this phosphatase. Activation of PP2A was assessed in BAEC by the extent of methylation and measurement of activity, and the enzyme was inhibited using selective pharmacological (okadaic acid, sodium fostriecin) and molecular (small interfering RNA) approaches. BAECs cultured in 30 mM glucose significantly increased PP2A methylation and activity, and PP2A inhibitors blocked these abnormalities. PP2A activity was increased also in aorta and retina from diabetic rats. NF-κB activity and cell death in BAEC were significantly increased in 30 mM glucose and inhibited by PP2A inhibition. NF-κB played a role in the hyperglycemia-induced death of BAEC, since blocking its translocation with SN50 also inhibited cell death. Inhibition of PP2A blocked the hyperglycemia-induced dephosphorylation of NF-κB and Bad, thus favoring cell survival. Incubation of benfotiamine with BAEC inhibited the high glucose-induced activation of PP2A and NF-κB and cell death, as well as several other metabolic defects, which likewise were inhibited by inhibitors of PP2A. Activation of PP2A contributes to endothelial cell death in high glucose, and beneficial actions of benfotiamine are due, at least in part, to inhibition of PP2A activation.

Priming patient safety: A middle-range theory of safety goal priming via safety culture communication.

Science.gov (United States)

Groves, Patricia S; Bunch, Jacinda L

2018-05-18

The aim of this paper is discussion of a new middle-range theory of patient safety goal priming via safety culture communication. Bedside nurses are key to safe care, but there is little theory about how organizations can influence nursing behavior through safety culture to improve patient safety outcomes. We theorize patient safety goal priming via safety culture communication may support organizations in this endeavor. According to this theory, hospital safety culture communication activates a previously held patient safety goal and increases the perceived value of actions nurses can take to achieve that goal. Nurses subsequently prioritize and are motivated to perform tasks and risk assessment related to achieving patient safety. These efforts continue until nurses mitigate or ameliorate identified risks and hazards during the patient care encounter. Critically, this process requires nurses to have a previously held safety goal associated with a repertoire of appropriate actions. This theory suggests undergraduate educators should foster an outcomes focus emphasizing the connections between nursing interventions and safety outcomes, hospitals should strategically structure patient safety primes into communicative activities, and organizations should support professional development including new skills and the latest evidence supporting nursing practice for patient safety. © 2018 John Wiley & Sons Ltd.

Cultural Consensus Theory: Aggregating Continuous Responses in a Finite Interval

Science.gov (United States)

Batchelder, William H.; Strashny, Alex; Romney, A. Kimball

Cultural consensus theory (CCT) consists of cognitive models for aggregating responses of "informants" to test items about some domain of their shared cultural knowledge. This paper develops a CCT model for items requiring bounded numerical responses, e.g. probability estimates, confidence judgments, or similarity judgments. The model assumes that each item generates a latent random representation in each informant, with mean equal to the consensus answer and variance depending jointly on the informant and the location of the consensus answer. The manifest responses may reflect biases of the informants. Markov Chain Monte Carlo (MCMC) methods were used to estimate the model, and simulation studies validated the approach. The model was applied to an existing cross-cultural dataset involving native Japanese and English speakers judging the similarity of emotion terms. The results sharpened earlier studies that showed that both cultures appear to have very similar cognitive representations of emotion terms.

Theory of mind and executive function during middle childhood across cultures.

Wang, Zhenlin; Devine, Rory T; Wong, Keri K; Hughes, Claire

2016-09-01

Previous studies with preschoolers have reported "East-West" contrasts in children's executive function (East>West) and theory of mind (Easttheory of mind. With respect to theory of mind, therefore, pedagogical experiences appear to be more salient than factors related to the broad contrast between individualist and collectivist cultures. Our findings also contribute to the debate surrounding the relationship between theory of mind and executive function; although scores on these two sets of tasks were robustly correlated within each country, the double dissociation between delayed theory of mind but superior executive function for children in local schools in Hong Kong compared with their U.K. peers suggests that variation in executive function may be necessary but is not sufficient to explain variation in theory of mind.

2011-01-01

This article examines theoretical thoughts of social learning theory and behavioral therapy and their influences on human behavior within a social and cultural context. The article utilizes two case illustrations with applications for consumers. It points out the abundance of research studies concerning the effectiveness of social learning theory, and the paucity of research studies regarding effectiveness and evidence-based practices with diverse groups. Providing a social and cultural context in working with diverse groups with reference to social learning theory adds to the literature for more cultural considerations in adapting the theory to women, African Americans, and diverse groups.

A study of low momentum antiproton-proton interactions in the momentum range 0.7 to 2.4 GeV/c has yielded differential cross sections for the elastic channel. An observation of one property of the data when compared with pp elastic scattering within the framework of quark- parton models is presented. The pp and pp systems, related by crossing symmetry, provided significant constraints on any particular model. (13 refs).

More than culture: structural racism, intersectionality theory, and immigrant health.

Viruell-Fuentes, Edna A; Miranda, Patricia Y; Abdulrahim, Sawsan

Explanations for immigrant health outcomes often invoke culture through the use of the concept of acculturation. The over reliance on cultural explanations for immigrant health outcomes has been the topic of growing debate, with the critics' main concern being that such explanations obscure the impact of structural factors on immigrant health disparities. In this paper, we highlight the shortcomings of cultural explanations as currently employed in the health literature, and argue for a shift from individual culture-based frameworks, to perspectives that address how multiple dimensions of inequality intersect to impact health outcomes. Based on our review of the literature, we suggest specific lines of inquiry regarding immigrants' experiences with day-to-day discrimination, as well as on the roles that place and immigration policies play in shaping immigrant health outcomes. The paper concludes with suggestions for integrating intersectionality theory in future research on immigrant health. Copyright © 2012 Elsevier Ltd. All rights reserved.

2013-01-01

Conspiracy theories are ubiquitous when it comes to explaining political events and societal phenomena. Individuals differ not only in the degree to which they believe in specific conspiracy theories, but also in their general susceptibility to explanations based on such theories, that is, their conspiracy mentality. We present the Conspiracy Mentality Questionnaire (CMQ), an instrument designed to efficiently assess differences in the generic tendency to engage in conspiracist ideation within and across cultures. The CMQ is available in English, German, and Turkish. In four studies, we examined the CMQ’s factorial structure, reliability, measurement equivalence across cultures, and its convergent, discriminant, and predictive validity. Analyses based on a cross-cultural sample (Study 1a; N = 7,766) supported the conceptualization of conspiracy mentality as a one-dimensional construct across the three language versions of the CMQ that is stable across time (Study 1b; N = 141). Multi-group confirmatory factor analysis demonstrated cross-cultural measurement equivalence of the CMQ items. The instrument could therefore be used to examine differences in conspiracy mentality between European, North American, and Middle Eastern cultures. In Studies 2–4 (total N = 476), we report (re-)analyses of three datasets demonstrating the validity of the CMQ in student and working population samples in the UK and Germany. First, attesting to its convergent validity, the CMQ was highly correlated with another measure of generic conspiracy belief. Second, the CMQ showed patterns of meaningful associations with personality measures (e.g., Big Five dimensions, schizotypy), other generalized political attitudes (e.g., social dominance orientation and right-wing authoritarianism), and further individual differences (e.g., paranormal belief, lack of socio-political control). Finally, the CMQ predicted beliefs in specific conspiracy theories over and above other individual

Penicillium purpurogenum is the fungus that produces an azaphilone pigment. However, details about the pigment biosynthesis pathway are unknown. The violet pigment PP-V is the one of the main pigments biosynthesized by this fungus. This pigment contains an amino group in a pyran ring as its core structure. We focused on this pigment and examined the relationship between intracellular ammonium concentration and pigment production using glutamine as a nitrogen source. The intracellular ammonium level decreased about 1.5-fold in conditions favoring PP-V production. Moreover, P. purpurogenum was transferred to medium in which it commonly produces the related pigment PP-O after cultivating it in the presence or absence of glutamine to investigate whether this fungus biosynthesizes PP-V using surplus ammonium in cells. Only mycelia cultured in medium containing 10 mM glutamine produced the violet pigment, and simultaneously intracellular ammonium levels decreased under this condition. From comparisons of the amount of PP-V that was secreted with quantity of surplus intracellular ammonium, it is suggested that P. purpurogenum maintains ammonium homeostasis by excreting waste ammonium as PP-V.

Carr, J M

1998-01-01

Vigilance, or the close, protective involvement of families caring for hospitalized relatives, was explored in this study using holistic ethnography. Leininger's theory of cultural care diversity and universality provided direction for the researcher to generate substantive data about the meanings, patterns, and day-to-day experience of vigilance. Five categories of meaning were derived from the data: commitment to care, emotional upheaval, dynamic nexus, transition, and resilience. The research findings expand understanding of vigilance as a caring expression, suggest direction for nursing practice, and contribute to Leininger's theory of cultural care diversity and universality and the development of nursing science.

Bioencapsulation of microbial cells in silica-based matrices has proved to be a good strategy to enhance the biosynthetic capabilities and viability of bioproducers. In the present study, mycelium and pellet cultures of strain Aspergillus oryzae PP were successfully immobilized in sol-gel hybrid matrices composed of tetraethylorthosilicate as an inorganic precursor, 5% (w/v) starch and 10 or 15% (w/v) polyethylene oxide, or 10% (w/v) calcium alginate as organic compounds. Biosynthetic activity of immobilized cultures was investigated by batch and fed-batch cultivation and the obtained results of 3042.04 IU cm -3 were comparable with the enzyme activity of the free cell culture. Immobilized cultures retained their viability and biosynthetic capabilities up to the 744th h during fed-batch fermentation processes. Consequently, sol-gel encapsulation in hybrid matrices could be considered as a promising technique for immobilization of Aspergillus oryzae PP in order to increase the α-amylase production.

2008-01-01

People can live longer and healthier lives by engaging in physical activity (PA). The purpose of this article is to assess the social cognitive theory (SCT) in relation to its relevance to produce cultural-specific directions for gerontological nursing practice in order to guide the design of PA interventions for Korean-American elders. SCT is compared to the Korean cultural, social, and health belief system and is analyzed and evaluated based on 3 criteria: assumptions of the theory, completeness and consistency, and essence of nursing. Within the Korean culture, as presumed in the SCT and the nursing paradigm, health-promoting behavior, such as PA, is conceptualized as the desire for a higher level of health rather than a fear of disease as is proposed by other health behavior theories. SCT with the integration of Korean culture recognizes cultural, developmental, societal, and other external constraints that may help in formulating interventions and better understanding of the limits faced by older Korean-Americans (OKAs) in their pursuit of routine PA.

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

2011-09-01

To examine cultural contrasts in the ordered sequence of conceptual developments leading to theory of mind (ToM), we compared 135 3- to 6-year-olds (77 Australians; 58 Iranians) on an established 5-step ToM scale (Wellman & Liu, 2004). There was a cross-cultural difference in the sequencing of ToM steps but not in overall rates of ToM mastery. In line with our predictions, the children from Iran conformed to a distinctive sequence previously observed only in children in China. In contrast to the case with children from Australia (and the United States), knowledge access was understood earlier than opinion diversity in children from Iran, consistent with this collectivist culture's emphasis on filial respect, dispute avoidance, and acquiring knowledge. Having a sibling was linked with faster overall ToM progress in Australia only and was not related to scale sequences in either culture.

The measurements described in this report are part of the infiltration experiment carried out at Olkiluoto. The emphasis of these measurements is on obtaining more detailed data on hydraulically significant fractures in the infiltration experiment area. The selected fractures or sections were pumped in turn and flow responses were observed in the other holes by the PFL DIFF-tool. The flow measurements were carried out in drillholes OL-KR14, OL-KR30, OL-PP66, OL-PP67, OL-PP68 and OL-PP69 on the Olkiluoto investigation site between January 2013 and July 2013. Two different flowmeters were used for the measurements. Posiva Flow Log, Difference flow method (PFL DIFF) was used for the determination of hydraulic conductivity and hydraulic head in fractures/fractured zones in the drillholes. PFL DIFF flow logging was conducted in all the drillholes mentioned above. Posiva Flow Log, Transverse flow method (PFL TRANS) was used to determine groundwater flow direction and flow rate across a drillhole. The transverse flow method was used in drillholes OL-KR14 and OL-PP69. PFL DIFF and PFL TRANS measurements had been carried out earlier in drillholes OL-PP66, OL-PP67, OL-PP68 and OL-PP69. The most recent measurements were conducted in 2011. Those measurements were carried out when drillhole OL-KR14 was pumped at packed-off section 13 m - 18 m. Both PFL DIFF and PFL TRANS flowmeters include an electrode for measuring single point resistance (SPR). The device has a high depth resolution and the results were used for depth synchronisation between consecutive DIFF and TRANS measurements. (orig.)

Designing to Partner/Partnering to Design: Exploring Synergies between Cultural Transformation and Design toward a Partnership Society

2015-07-01

Full Text Available What is Cultural Transformation Theory? What is design, and design thinking? How do these topics connect with concepts of culture and material culture? How are domination and partnership as paradigms of cultural transformation expressed in design? How can design and partnership work together to achieve a partnership society, and what actions does this suggest for the future? This article addresses these questions, identifies key elements of Cultural Transformation Theory, and introduces the concepts of design and design thinking and the aspects of design as product and process. Definitions of culture and material culture that reveal a disconnect with design are discussed. This article makes the case that design and culture are reciprocally connected, and uses specific cross-cultural examples of domination and partnership as manifested in design disciplines of architecture. Current ways in which the emerging field of design thinking incorporates a partnership approach are also discussed. Finally, the article suggests ways in which cultural transformation and design can work synergistically, evolving cultures toward a partnership future while creating design expressions of such a culture.

Race, Class, and Cultural Reproduction: Critical Theories in Urban Education

Directory of Open Access Journals (Sweden)

Elaine M. Walker

2003-11-01

Full Text Available In spite of decades of reform attempts urban education remains an intractable policy issue for educators. National and state level data continue to show disparities in educational achievement and attainment between students from affluent and poor urban communities. If past policies have not proven to be effective in substantially improving urban educational systems the question is why? In this paper the argument is raised that urban educational policies lack sound epistemological grounding. Policies are divorced from an understanding of the “urban problematic”. Functionalist in orientation these policies have for the most part sought to “fix” urban schools by focusing on micro-ecological issues. In this paper three theoretical perspectives are explored for their potential contribution to inform research and policy on urban educational issues. The three perspectives are: 1 class theories 2 critical race theory and 3 cultural reproduction theories.

Birefringence induced by pp-wave modes in an electromagnetically active dynamic aether

Alpin, Timur Yu.; Balakin, Alexander B.

2017-01-01

In the framework of the Einstein-Maxwell-aether theory we study the birefringence effect, which can occur in the pp-wave symmetric dynamic aether. The dynamic aether is considered to be a latently birefringent quasi-medium, which displays this hidden property if and only if the aether motion is non-uniform, i.e., when the aether flow is characterized by the non-vanishing expansion, shear, vorticity or acceleration. In accordance with the dynamo-optical scheme of description of the interaction between electromagnetic waves and the dynamic aether, we shall model the susceptibility tensors by the terms linear in the covariant derivative of the aether velocity four-vector. When the pp-wave modes appear in the dynamic aether, we deal with a gravitationally induced degeneracy removal with respect to hidden susceptibility parameters. As a consequence, the phase velocities of electromagnetic waves possessing orthogonal polarizations do not coincide, thus displaying the birefringence effect. Two electromagnetic field configurations are studied in detail: longitudinal and transversal with respect to the aether pp-wave front. For both cases the solutions are found, which reveal anomalies in the electromagnetic response on the action of the pp-wave aether mode. (orig.)

Weibo Chen

2013-01-01

Full Text Available PP2A is a family of mammalian serine/threonine phosphatases that is involved in the control of many cellular functions including protein synthesis, cellular signaling, cell cycle determination, apoptosis, metabolism, and stress responses through the negative regulation of signaling pathways initiated by protein kinases. Rapid progress is being made in the understanding of PP2A complex and its functions. Emerging studies have correlated changes in PP2A with human diseases, especially cancer. PP2A is comprised of 3 subunits: a catalytic subunit, a scaffolding subunit, and a regulatory subunit. The alternations of the subunits have been shown to be in association with many human malignancies. Therapeutic agents targeting PP2A inhibitors or activating PP2A directly have shed light on the therapy of cancers. This review focuses on PP2A structure, cancer-associated mutations, and the targeting of PP2A-related molecules to restore or reactivate PP2A in anticancer therapy, especially in digestive system cancer therapy.

Polypropylene (PP)'s low impact strength limits its usages. Adding some a rare earth polymer can enhance PP's tensile strength and impact strength. Acrylic lanthanum was prepared by the reaction between lanthanum oxide and acrylic acid. The IR spectrum prove that and optimum reacting conditions are that the bulk ratio of La(AA) 3 and MMA is not less than one and temperature is about 80 ℃. Lanthanum containing Polymer were added into PP. When percent of addition only was 3%, strength were enhanced 10% , and impact strength 40%. SEM shows the compatibility of rare earth polymer and PP; lanthanum containing polymer can form physical crosslinking between PP's molecules, then every particle's surface connect with several PP molecules and the PP mechanical property were enhanced.

Primary trauma injury was achieved by rolling a stainless steel cylinder (0.9 g) on the organotypic slices. Secondary injury was followed after dropping a weight (0.137 g) on a localised area of the organotypic slice, from a height of 2 mm. The time course and extent of cell death were determined by measuring the fluorescence of the viability indicator propidium iodide (PI) at several time points after the injury. The initial localised impact damage spread 24 and 67 h after injury, cell death being 25% and 54%, respectively, when slices were kept at 37 degrees C. To validate these methods as models to assess neuroprotective strategies, similar insults were applied to slices at relatively low temperatures (30

Korea has the highest suicide rate amongst the OECD countries. Yet, its research on suicidal behaviors has been primitive. While the Interpersonal Psychological Theory of Suicide has gained global attention, there has only been a few researches, which examined its applicability in Korea. In this article, we review the previous studies on suicide and examine the association between the Interpersonal Psychological Theory of Suicide and traditional Korean culture, with an emphasis on Collectivism and Confucianism. We propose that pathways to suicide might vary depending on cultural influences. Clinical implications and suggestions for future research will be discussed.

Full Text Available Article discussed how native speakers of Indonesian observed Grice’s maxims. One hundred conversations contributed in live talk show from varied Indonesia television channels were analysed. The results show that Grice’s maxims are fulfilled in many conversations. Nevertheless, in other situations, two kinds of non-fulfilment of the maxims are observed. First, the speaker deliberately exploits a maxim, which is suitable to Grice’s theory. Second, the speaker fails to observe but does not exploit a maxim, which leads to some interpretations of the cultural patterns of the Indonesian language: communicative politeness, high context culture and the needs of harmony in communication that are considered as the manifesting of Indonesian culture.

The human cytomegalovirus tegument protein pp71 localizes to the nucleus immediately upon infection, and functions to initiate viral gene expression. Analysis of a series of random insertion mutations revealed that sequences within the mid region (MR) of pp71 are important for localization to the nucleus. Fusion of MR sequences with eGFP revealed that amino acids 94 to 300 were sufficient to target proteins to the nucleus. Random substitution mutagenesis within this domain resulted in two double substitution mutants, pp71P203T/T223M and pp71T228M/L275Q, with a predominantly cytoplasmic localization. Disruption of nuclear targeting resulted in relocalization of the fusion proteins to a distinct perinuclear region. Using tandem mass spectrometry, we determined that threonine 223 can be phosphorylated. Mutation of this residue to a phosphomimetic amino acid resulted in abrogation of nuclear targeting. These results strongly suggest that the intracellular trafficking of pp71 is regulated by phosphorylation

In spite of its popularity, the notion of culture within the macrosystem, as a separate entity of everyday practices and therefore microsystems, is problematic. Using the theoretical and empirical work of Rogoff and Weisner, and influenced as they are by Vygotsky's sociocultural perspective, we reconceptualize Bronfenbrenner's model by placing culture as an intricate part of proximal development processes. In our model, culture has the role of defining and organizing microsystems and therefore becomes part of the central processes of human development. Culture is an ever changing system composed of the daily practices of social communities (families, schools, neighborhoods, etc.) and the interpretation of those practices through language and communication. It also comprises tools and signs that are part of the historical legacy of those communities, and thus diversity is an integral part of the child's microsystems, leading to culturally defined acceptable developmental processes and outcomes.

Analysis of pp and pp-bar elastic scattering amplitudes at high energies

Energy Technology Data Exchange (ETDEWEB)

Ferreira, E.; Kodama, T.; Kohara, A.K. [Universidade Federal do Rio de Janeiro (IF/UFRJ), RJ (Brazil). Inst. de Fisica

Full text: A careful analysis of high energies elastic scattering data at 7 TeV for pp, 1800 - 1950 GeV for pp-bar and 540 -541 GeV for pp-bar in terms of its amplitudes has been performed as natural extension of previous analysis for lower energies. The disentanglement of the real and imaginary parts is written consistently with constraints from dispersion relations for amplitudes and for slopes, and also satisfying the universal asymptotic behavior for large |t| values due to the three gluon Exchange process. Values for the imaginary and real slopes and for the total cross section at 7 TeV, 1800-1950 GeV and 540-541 GeV are presented, and the shape of the differential cross section at 14 TeV, with a dip/bump structure more marked and at a smaller values of |t| is predicted. It is predicted that future measurements at large |t| will be connected smoothly with the perturbative tail observed in the interval 5.5 to 14.2 GeV{sup 2} at lower energies and that a marked dip would be observed in pp-bar scattering near this tail range. It is stressed for the consistent description of elastic pp and pp-bar data and pointed out the importance of the future measurements in the Coulomb interference range and in the transition range to the perturbative tail where the perturbative and non-perturbative effects appears together.

Marcincin, A.; Hricova, M.; Ujhelyiova, A.

2014-08-01

In this paper, the effect of the compatibilisers-dispersants and other nanofillers on melt spinning of the polypropylene (PP) composites, containing carbon nanotubes (CNTs), and carbon black pigment (CBP) has been investigated. Further, the structure and selected properties of composite fibers, such as mechanical and electrical have been studied. The results revealed, that percolation threshold for PP/CBP composite fibres was situated within the concentration of 15 - 20 wt%, what is several times higher than for PP/CNTs fibers.

Cultural Consensus Theory for the ordinal data case.

Science.gov (United States)

Anders, Royce; Batchelder, William H

2015-03-01

A Cultural Consensus Theory approach for ordinal data is developed, leading to a new model for ordered polytomous data. The model introduces a novel way of measuring response biases and also measures consensus item values, a consensus response scale, item difficulty, and informant knowledge. The model is extended as a finite mixture model to fit both simulated and real multicultural data, in which subgroups of informants have different sets of consensus item values. The extension is thus a form of model-based clustering for ordinal data. The hierarchical Bayesian framework is utilized for inference, and two posterior predictive checks are developed to verify the central assumptions of the model.

Properties of PP/MWCNT-COOH /PP composites made by melt mixing versus solution cast /melt mixing methods

International Nuclear Information System (INIS)

Reinholds, I; Roja, Z; Zicans, J; Meri, R Merijs; Bitenieks, J

2015-01-01

An approach on improvement of the properties of polypropylene / carbon nanotube (PP/CNT) composites is reported. PP blend compositions with carboxylic acid functionalized multi-walled carbon nanotubes (MWCNT-COOH) at filler content 1.0 wt.% were researched. One part of the composites was manufactured by direct thermoplastic mixing PP with the filler, but the other one was made from solution casted masterbatch with the following thermoplastic mixing. An increase of mechanical properties (Young's modulus, storage modulus and tensile strength), compared to an increase of glass transition temperature indicated a reinforcement effect of CNTs on PP matrix, determined from the tensile tests and differential mechanical analysis (DMA), while the elongation was reduced, compared to PP matrix. By differential scanning calorimetry (DSC) analysis, the effect of nanofiller on the reorganization of PP crystallites was observed. A noticeable enhanced effect on increase of the crystallization temperature was indicated for masterbatch manufactured composite. An increase of thermal stability was also observed, compared to pristine PP and the composite made by direct thermoplastic mixing PP with the filler

This study tested key tenets of objectification theory with South Korean women and explored the roles of sexually objectifying media and culture-specific standards of beauty in body image and eating disorder symptoms. Two pilot studies with South Korean college women (n = 40, n = 30) revealed that facial characteristics such as size and shape represent a discrete variable among culture-specific standards of beauty for South Korean women. Results with a sample of 562 South Korean college women indicated that media exposure had significant positive indirect relations with body shame and eating disorder symptoms through the mediating roles of internalization, body surveillance, and face surveillance. Internalization of cultural standards of beauty had significant positive direct relations with body surveillance and face surveillance and had both direct and indirect relations with body shame and eating disorder symptoms. Body and face surveillances had significant positive direct relations with body shame and had indirect relations with eating disorder symptoms. Finally, body shame mediated the links from internalization and surveillance variables to eating disorder symptoms. The results support the applicability of objectification theory as it relates to South Korean women and point to the significance of culture-specific standards of beauty within that framework. These findings could contribute to the broader field of multicultural body image research, with potential implications for therapist practices and training.

Care and cultural context of Lebanese Muslim immigrants: using Leininger's theory.

Science.gov (United States)

Luna, L

1994-01-01

The purpose of this ethnonursing study was to describe and analyze the meanings and experiences of care for Lebanese Muslims as influenced by cultural context in selected natural and community settings. Leininger's theory of Cultural Care Diversity and Universality served as the conceptualizing frame-work for the study. Research questions focused on discovering the meanings and experiences of care as influenced by world view, social structure, and cultural context in the hospital, clinic, and home. Ethno-nursing research methods were used with key and general informants in an urban US community. The majority of informants were new immigrants living less than 10 years in the US. Universal themes of care that were similar in the three contexts reflected care as a religious obligation in Islam, care as equal but different gender role responsibilities, and care as individual and collective meanings of honor. This article also presents findings related to gender role responsibilities. Nursing decisions and actions using Leininger's three modes were identified to achieve culturally congruent nursing care.

Measuring Individual Differences in Generic Beliefs in Conspiracy Theories Across Cultures: The Conspiracy Mentality Questionnaire (CMQ

Directory of Open Access Journals (Sweden)

Martin eBruder

2013-04-01

Full Text Available Conspiracy theories are ubiquitous when it comes to explaining political events and societal phenomena. Individuals differ not only in the degree to which they believe in specific conspiracy theories, but also in their general susceptibility to explanations based on such theories, that is, their conspiracy mentality. We present the Conspiracy Mentality Questionnaire (CMQ, an instrument designed to efficiently assess differences in the generic tendency to engage in conspiracist ideation within and across cultures. The CMQ is available in English, German, and Turkish. In four studies, we examined the CMQ’s factorial structure, reliability, measurement equivalence across cultures, and its convergent, discriminant, and predictive validity. Analyses based on a cross-cultural sample (Study 1a; N = 7,766 supported the conceptualization of conspiracy mentality as a one-dimensional construct across the three language versions of the CMQ that is stable across time (Study 1b; N = 141. Multigroup confirmatory factor analysis demonstrated cross-cultural measurement equivalence of the CMQ items. The instrument could therefore be used to examine differences in conspiracy mentality between European, North American, and Middle Eastern cultures. In Studies 2-4 (total N = 476, we report (re-analyses of 3 datasets demonstrating the validity of the CMQ in student and working population samples in the UK and Germany. First, attesting to its convergent validity, the CMQ was highly correlated with another measure of generic conspiracy belief. Second, the CMQ showed patterns of meaningful associations with personality measures (e.g., Big Five dimensions, schizotypy, other generalized political attitudes (e.g., social dominance orientation and right-wing authoritarianism, and further individual differences (e.g., paranormal belief, lack of socio-political control. Finally, the CMQ predicted beliefs in specific conspiracy theories over and above other individual

Cultural-Ecological Theory of Academic Disengagement Used to Explain a Story of Race, Culture and Education.

Science.gov (United States)

Ogunyemi, Boluwaji

2017-01-01

Students of African ancestry often share an experience of being a racialized minority in the context of the educational institution. Late Professor of Anthropology John Ogbu's Cultural-ecological Theory of Academic Disengagement is employed to describe the negative responses encountered by peers in the name of academic achievement. The late Nigerian-American anthropologist John Ogbu described that it is often socially disadvantageous for black youth to prosper academically in formal education. Black students are often seen as betraying their cultural identities by aspiring to academic success and scholastic achievement and are met with repugnance by black peers. The notion of "acting white" is unnecessary, impertinent should be abandoned outright as achievement should have no color. Copyright © 2017 National Medical Association. Published by Elsevier Inc.

Briggs, Harold Eugene; Sharkey, Caroline; Briggs, Adam Christopher

2016-01-01

In this article the authors tie the emergence of an empirical practice research culture, which enabled the rise in evidence-based practice in social work to the introduction of applied behavior analysis and behavioral theory to social work practice and research. The authors chronicle the: (1) scientific foundations of social work, (2) influence and push by corporatized university cultures for higher scholarship productivity among faculty, (3) significance of theory in general, (4) importance of behavioral theory in particular as a major trigger of the growth in research on effective social work practice approaches, and (5) commonalities between applied behavior analysis and evidence-based practice. The authors conclude with implications for addressing the dual challenges of building an enhanced research culture in schools of social work and the scholarship of transferring practice research to adoption in real world practice settings.

AIDS and the question of culture: focus on social cognitive theory.

Kim, Suk-hee

2010-01-01

Each of us has a variety of personal theories we use to explain physical, biological, and interpersonal phenomena. Also, our personal theories are our guides as we move toward greater meaning and belief in our lives. This writing shows the reason to utilize the new/recent theory approach in social work practice concerning the issue of AIDS in a cultural-based study on a micro level, though it may compete with macro-level values equally. The social work practice setting needs to open up for engaging dialogue with individuals and large groups within a safe environment and a positive attitude. Not only does this gate allow us to understand clients' and social workers' ways of doing, being, and saying but also ways in which our audience/player (client/we) can perform their/our power of talking about AIDS without fear, guilt, shame, and feelings of despair.

The Psychological Aspect of Safety Culture: Application of the Theory of Generations for the Formation of Safety Culture Among Personnel

International Nuclear Information System (INIS)

Melnitckaia, T.B.

2016-01-01

The formation of safety culture is an attempt of constructive influence on the socio psychological atmosphere of the team and the behavior of employees. By way of creating specific settings, the value system for the organization staff as part of the organizational culture, it is possible to forecast, plan and promote the desired behavior. However, it is necessary to take into account the corporate culture spontaneously established in the organization. The leaders often try to establish a safety culture, where the progressive values, norms are declared, and the results obtained are not those expected. This is partly because the organizational norms and values implemented come into conflict with reality and, therefore, are actively rejected by many members of the organization. The theory of generations developed by the American scientists (N. Howe, W. Strauss) helps in the analysis and consideration of the staff values formed under the influence of many factors, depending on the age of employees, in the course of safety culture formation.

Guiding the Process of Culturally Competent Care With Hispanic Patients: A Grounded Theory Study.

Science.gov (United States)

Sobel, Linda L; Metzler Sawin, Erika

2016-05-01

To explore nursing care actions that lead to culturally competent care for Hispanic patients. Nurses report apprehension when delivering nursing care because of language barriers and a lack of Hispanic cultural understanding. Research is needed to inform culturally aware nursing practice actions for Hispanic patients. The study used a qualitative, grounded theory design to address the questions: (a) What cultural knowledge should nurses have when caring for Hispanic patients and families and (b) What nursing actions should nurses take to provide culturally competent care? Hispanic lay health promoters and Hispanic community members were interviewed to make recommendations for care. A model was identified that informs culturally competent nursing care. "Connectedness," the central phenomenon, describes nursing actions and contains subthemes explaining influences on nursing care. "Up to You" and "At the Mercy of the System" are descriptive themes influencing connectedness. Connectedness is central to culturally well-informed nurse-patient interactions. © The Author(s) 2014.

2014-01-01

Full Text Available The HADES collaboration has searched for the anti-kaonic nuclear cluster “ppK−” in p+p collisions by its decay into pΛ. In the course of this analysis several cross checks had to be performed. This report discusses two examples thereof. In one test it was checked whether the presence of background events could introduce a bias on the applied partial wave analysis. The second item discussed here is the extraction of the total pK+Λ production cross section necessary to derive the absolute upper limit on the “ppK−” production cross section.

anti pp and pp elastic scattering from 10 GeV to 1000 GeV centre-of-mass energy

1984-06-21

Antiproton-proton and proton-proton elastic scattering are studied simultaneously over the energy range ..sqrt..anti s approx.= (10/1000) GeV in a nucleon valence core model proposed earlier. The scattering is described as primarily due to two processes: diffraction and hard scattering. The latter originates from the scattering of a nucleon core off another core. Destructive interference between the two processes produces dips in anti pp and pp differential cross-sections. As energy increases beyond the ISR range (..sqrt..anti s = (23/62) GeV), the dips get filled up, and eventually transform into shoulders or breaks at collider energies. Differences between anti pp and pp differential cross-sections persist even at collider energies. Comparison with ISR data shows that the model provides a quantitative description of pp elastic scattering in this energy range. Predictions of anti pp and pp differential cross-sections at future collider energies ..sqrt..s = 800 and 2000 GeV are given. In order to distinguish between competing models, need for measuring the anti pp differential cross-section at the ISR and SPS collider in the vertical stroketvertical stroke-range (0.5/2.0) (GeV)/sup 2/ is stressed.

Culture and the Trajectories of Developmental Pathology: Insights from Control and Information Theories.

Science.gov (United States)

Wallace, Rodrick

2018-06-01

Cognition in living entities-and their social groupings or institutional artifacts-is necessarily as complicated as their embedding environments, which, for humans, includes a particularly rich cultural milieu. The asymptotic limit theorems of information and control theories permit construction of a new class of empirical 'regression-like' statistical models for cognitive developmental processes, their dynamics, and modes of dysfunction. Such models may, as have their simpler analogs, prove useful in the study and re-mediation of cognitive failure at and across the scales and levels of organization that constitute and drive the phenomena of life. These new models particularly focus on the roles of sociocultural environment and stress, in a large sense, as both trigger for the failure of the regulation of bio-cognition and as 'riverbanks' determining the channels of pathology, with implications across life-course developmental trajectories. We examine the effects of an embedding cultural milieu and its socioeconomic implementations using the 'lenses' of metabolic optimization, control system theory, and an extension of symmetry-breaking appropriate to information systems. A central implication is that most, if not all, human developmental disorders are fundamentally culture-bound syndromes. This has deep implications for both individual treatment and public health policy.

Narrated Political Theory: Theorizing Pop Culture in Dietmar Dath’s Novel Für immer in Honig

Directory of Open Access Journals (Sweden)

Georg Spitaler

2013-12-01

Full Text Available In recent decades, debates on the relationship between pop culture and the political have transgressed academia and have even been prominent in pop (media discourses and texts, including pop literature. Amongst the contributions at the inter-section of art, theory and entertainment are the novels and essays by the German author Dietmar Dath. Taking the example of his novel Für immer in Honig (Berlin 2005/2008, it will be discussed how the book reloads and theorizes pop culture, and how a common cultural-theoretical narrative of de-politicized pop is challenged by the imaginative narratives of the novel. It will be argued that Dath’s references to affective ‘mattering maps’ of pop culture, that on the one hand tend to fall into the pitfalls of exclusive ‘pop sophis-tication’, nevertheless play a key role for his aesthetical/theoretical project of political emancipation, and that these references can be viewed as examples of why popular passions matter for the formation of political identities/subjectivities as well as for the production and reading of political theory.

Deconstructing dementia and delirium hospital practice: using cultural historical activity theory to inform education approaches.

Science.gov (United States)

Teodorczuk, Andrew; Mukaetova-Ladinska, Elizabeta; Corbett, Sally; Welfare, Mark

2015-08-01

Older patients with dementia and delirium receive suboptimal hospital care. Policy calls for more effective education to address this though there is little consensus on what this entails. The purpose of this clarification study is to explore how practice gaps are constructed in relation to managing the confused hospitalised older patient. The intent is to inform educational processes in the work-place beyond traditional approaches such as training. Adopting grounded theory as a research method and working within a social constructionist paradigm we explored the practice gaps of 15 healthcare professionals by interview and conducted five focus groups with patients, carers and Liaison mental health professionals. Data were thematically analysed by constant comparison and theoretical sampling was undertaken until saturation reached. Categories were identified and pragmatic concepts developed grounded within the data. Findings were then further analysed using cultural historical activity theory as a deductive lens. Practice gaps in relation to managing the confused older patient are determined by factors operating at individual (knowledge and skill gaps, personal philosophy, task based practice), team (leadership, time and ward environmental factors) and organisational (power relationships, dominance of medical model, fragmentation of care services) levels. Conceptually, practice appeared to be influenced by socio-cultural ward factors and compounded by a failure to join up existing "patient" knowledge amongst professionals. Applying cultural historical activity theory to further illuminate the findings, the central object is defined as learning about the patient and the mediating artifacts are the care relationships. The overarching medical dominance emerges as an important cultural historical factor at play and staff rules and divisions of labour are exposed. Lastly key contradictions and tensions in the system that work against learning about the patient are

The purpose of this study was to discover the care expressions, practices, and patterns of elderly Anglo- and African American elders. The domain of inquiry was the cultural care of elderly residents within the environmental context of a long-term care institution. The ethnonursing qualitative research method was used to conduct the study which was conceptualized within Leininger's theory of culture care diversity and universality. Four major themes were discovered: (a) Residents expressed and lived generic care to maintain their preadmission lifeways; (b) The nursing staff provided aspects of professional care to support satisfying lifeways for residents; (c) Institutional care patterns and expressions were viewed as a continuing life experience but with major differences between the apartment section and nursing home units; and (d) An institutional culture of the retirement home was discovered which reflected unique lifeways and shared care and health expressions and practices. These themes substantiated the culture care theory and revealed new modes of care for the elderly in an institutional setting.

This forum constitutes a cogenerative inquiry using postcolonial theory drawn from the review paper by Zembylas and Avraamidou. Three teacher educators from African, Asian and Caribbean countries reflect on problems confronting their professional practices and consider the prospects of creating culturally inclusive science education. We learn that in Mozambique, Nepal and the Caribbean scientism patrols the borders of science education serving to exclude local epistemological beliefs and discourses and negating culturally contextualized teaching and learning. Despite the diverse cultural hybridities of these countries, science education is disconnected from the daily lives of the majority of their populations, serving inequitably the academic Western-oriented aspirations of an elite group who are "living hybridity but talking scientism." The discussants explore their autobiographies to reveal core cultural values and beliefs grounded in their non-Western traditions and worldviews but which are in conflict with the Western Modern Worldview (WMW) and thus have no legitimate role in the standard school/college science classroom. They reflect on their hybrid cultural identities and reveal the interplay of multiple selves grounded in both the WMW and non-WMWs and existing in a dialectical tension of managed contradiction in a Third Space. They argue for dialectical logic to illuminate a Third Space wherein students of science education may be empowered to challenge hegemonies of cultural reproduction and examine reflexively their own identities, coming to recognize and reconcile their core cultural beliefs with those of Western modern science, thereby dissipating otherwise strongly delineated cultural borders.

The linearity of the chains confers to iPP, low melt strength, which means a low strength to stretching during elongation. The increase of melt strength and the extensibility is due to the increase of the entanglement of the macromolecules chains. The HMS-PP (high melt strength polypropylene) was synthesized (based on the grains iPP) through gamma irradiation in the iPP under acetylene atmosphere followed by heat treatment for recombination and subsequent annihilation of the other free radicals. Samples of HMS-PP and iPP were subjected to environmental aging in IPEN - Sao Paulo and in the QUV chamber. The results show fractured surfaces of iPP and HMS-PP that are intensified with exposure time. The iPP degradation process has the predominance of chain scissions, with carbonyl and hydroperoxides formation which act as initiators of photo degradation mechanisms. (author)

Toxocariasis is one of the most important, but neglected, zoonoses, which is mainly caused by Toxocara canis. To better understand the role of serine/threonine protein phosphatase 1 (PP1) in reproductive processes of male adult T. canis, differential expression analysis was used to reveal the profiles of PP1 catalytic subunit α (PP1cα) gene Tc-stp-1 and PP1 regulatory subunit 7 (PP1r7) gene TcM-1309. Indirect fluorescence immunocytochemistry was carried out to determine the subcellular distribution of PP1cα. Double-stranded RNA interference (RNAi) assays were employed to illustrate the function and mechanism of PP1cα in male adult reproduction. Real-time quantitative PCR (qPCR) showed transcriptional consistency of Tc-stp-1 and TcM-1309 in sperm-producing germline tissues and localization research showed cytoplasmic distribution of PP1cα in sf9 cells, which indicated relevant involvements of PP1cα and PP1r7 in spermatogenesis. Moreover, spatiotemporal transcriptional differences of Tc-stp-1 were determined by gene knockdown analysis, which revealed abnormal morphologies and blocked meiotic divisions of spermatocytes by phenotypic aberration scanning, thereby highlighting the crucial involvement of PP1cα in spermatogenesis. These results revealed a PP1cα-PP1r7 mechanism by which PP1 regulates kinetochore-microtubule interactions in spermatogenesis and provided important clues to identify novel drug or vaccine targets for toxocariasis control.

The Cloning and Functional Characterization of Peach CONSTANS and FLOWERING LOCUS T Homologous Genes PpCO and PpFT.

Directory of Open Access Journals (Sweden)

Full Text Available Flowering is an essential stage of plant growth and development. The successful transition to flowering not only ensures the completion of plant life cycles, it also serves as the basis for the production of economically important seeds and fruits. CONSTANS (CO and FLOWERING LOCUS T (FT are two genes playing critical roles in flowering time control in Arabidopsis. Through homology-based cloning and rapid-amplifications of cDNA ends (RACE, we obtained full-lengths cDNA sequences of Prunus persica CO (PpCO and Prunus persica FT (PpFT from peach (Prunus persica (L. Batsch and investigated their functions in flowering time regulation. PpCO and PpFT showed high homologies to Arabidopsis CO and FT at DNA, mRNA and protein levels. We showed that PpCO and PpFT were nucleus-localized and both showed transcriptional activation activities in yeast cells, consistent with their potential roles as transcription activators. Moreover, we established that the over-expression of PpCO could restore the late flowering phenotype of the Arabidopsis co-2 mutant, and the late flowering defect of the Arabidopsis ft-1 mutant can be rescued by the over-expression of PpFT, suggesting functional conservations of CO and FT genes in peach and Arabidopsis. Our results suggest that PpCO and PpFT are homologous genes of CO and FT in peach and they may function in regulating plant flowering time.

Building a Cultural Heritage Corridor Based on Geodesign Theory and Methodology

Directory of Open Access Journals (Sweden)

Yang Chen

Full Text Available ABSTRACT: Geodesign is a type of methodology that integrates dynamic environment modeling based on GIS with planning and design in order to support relevant decision making. It has substantially changed the dominant ways of thinking in planning and design, and has solved spatial issues relating to cultural and natural resources from a new perspective. Taking the Qionglai section of the Southern Silk Road as an example, the present study implemented geodesign theory and methods to investigate the technical approach to building a cultural heritage corridor based on GIS spatial analysis and overlay analysis.Firstly, we analyzed the various data layers of the cultural and natural features in the planning region. We organized all the data based on the principle of classification, organizing it into categories such as natural, cultural, and recreational data. Therefore, we defined the theme of the Southern Silk Road as a historical cultural heritage corridor. Secondly, based on the background, the heritage corridor boundary was defined according to its natural, cultural, and administrative spatial characteristics, with the three thematic boundaries overlaid in order to define a boundary location area covering about 852 square kilometers. Next, we divided all of the resources into three categories: natural heritage resources, cultural heritage resources, and intangible heritage resources and recreational spaces. The elements which could be used to build up the cultural heritage corridor were selected by evaluation and spatial analysis. In this way, we obtained some conclusive spatial information, such as element structures, the heritage density distribution, and the heritage number distribution. Finally, within the heritage boundary, we connected the tangible and intangible heritage resources to form various kinds of linear spaces, with the aim of obtaining the spatial pattern of the heritage corridor.

The thermal drillhole device TERO76 (for diameter 76 mm drillholes) used in this study for determining thermal properties of rocks in situ was developed at the Geological Survey of Finland for Posiva in the early 2000's. The measurement method is based on monitoring the temperature variation of a cylindrical heating source in a drillhole. The measured data can be interpreted with full numerical 3D codes as well as with an analytical infinite line source method, a 'rapid interpretation tool', which makes it possible to calculate the first estimates of thermal properties already in the field. Both methods were applied in this study. Because of the unique measurement geometry, only the thermal conductivities can accurately be estimated using the late times of heating periods (accuracy ± 2%). The cylindrical source method cannot directly give the thermal diffusivity or volumetric heat capacity at a sufficient accuracy. Thermal diffusivities are estimated by using the average specific heat capacities and densities of the rock type at the measurement point, or the laboratory results on the general diffusivity-conductivity relationship for different Olkiluoto rock types. The latter technique was applied in this study. Thermal properties were determined in four shallow drillholes (ONK-PP398, ONK-PP399, ONK-PP405, ONK-PP411) located in the ONKALO investigation niche 3 (ONK-TKU-3620) at the access tunnel chainage of 3620 m. The measurement positions (17) were strictly selected on the grounds that approximately an equal number of in situ results would be available in both veined gneiss (VGN) and pegmatitic granite (PGR). The results from the drillholes ONK-PP340 and ONK-PP346 measured in a previous project are also presented in this report. In veined gneiss, the average conductivity determined with numerical model of the present measurements is 3.49 (2.83) Wm -1 K -1 and diffusivity 1.89 x 10 -6 (1.3 10 -6 ) m 2 s -1 .

NN wave function at small distances and hard bremsstrahlung in the process pp→ppγ

Neudatchin, V. G.; Khokhlov, N. A.; Shirokov, A. M.; Knyr, V. A.

1997-01-01

Various possibilities of studying the NN wave function at small distances--and in particular, quark degrees of freedom in the NN system--are discussed. It is shown that there is such a possibility at moderate energies--namely, hard bremsstrahlung in the process pp→ppγ at proton-beam energies in the range 350-450 MeV permits distinguishing between the pp wave function with nodes in S and P waves that corresponds to the Moscow potential of NN interaction from functions obtained with repulsive-core mesonic potentials. In the regions where photon energies in the c.m.s. are maximal (forward and backward photon emission angles in the laboratory frame), the pp→ppγ cross section calculated with the Moscow potential has maxima at which it is approximately five times larger than the analogous cross section calculated with repulsive-core mesonic potentials. The coordinate-representation formalism of the theory of bremsstrahlung is expounded

Understanding the nuclear controversy: An application of cultural theory

International Nuclear Information System (INIS)

Graaff, Shashi van de

2016-01-01

The need for a secure and sustainable energy future has become firmly entrenched on the global political agenda. Governments worldwide are seeking solutions that will ensure security of their energy supplies, while reducing carbon emissions in the fight against climate change. Advocates of nuclear power have reframed the technology as the most reliable, cost-effective and immediate solution to both of these policy problems, and predicted the emergence of a 'nuclear renaissance’. However, there is little evidence to date that suggests a nuclear renaissance has actually taken place. Public opinion polling demonstrates that many remain unconvinced of the need for nuclear power. This paper uses Cultural Theory as a heuristic to understand why the arguments for a nuclear renaissance have been largely unsuccessful. It argues that the failure of nuclear advocates to engage with a wider cross-section of world-views has prevented the controversy surrounding nuclear power from being resolved, and the nuclear renaissance from becoming a reality. In doing so, this paper builds upon a growing recognition of the contribution that social science research can make to understanding public acceptance of energy policy choices. - Highlights: • There is little evidence of a nuclear renaissance taking place in Western Europe or North America. • Public opinion on nuclear power continues to be deeply divided. • Pro-nuclear arguments are dominated by a particular cultural rationality. • A broader range of cultural perspectives needs to be recognised for the nuclear debate to progress.

Study of pp→ppη reaction at threshold

International Nuclear Information System (INIS)

Taleb, A.

1994-11-01

The η production has been studied through the pp → ppη reaction at threshold. Data were taken at the Synchrotron of the ''Laboratoire National Saturne''. The detection in coincidence of the two protons scattered near 0 deg and analysed with the magnetic spectrometer SPES3 allows the reconstruction of missing mass spectra for the η signature. A simulation program which takes into account all the experimental set up characteristics has been realized and tested through the pp → dπ + reaction detected simultaneously with pp → ppη. The generated proton momentum spectra for pp → ppη show a pronounced η mass dependence. This characteristic, connected to the kinematical properties of pp → ppη at threshold, is used to extract the mass of the meson η. The obtained value, m η = 547.65 ± 0.18 MeV, is in good agreement with measurement done recently through the pd → H eη reaction. The total cross section σ t of pp → ppη measured at 1260, 1265 and 1300 MeV presents a strong energy dependence. This cross section increases less with energy than the phase-space. The influence of p-p and η-p final state interactions in our measurements is studied. Our results are compared with theoretical predictions and assess the dominant character of the baryonic resonance N * (1535) in the η mechanism production at threshold. These experimental results give an energy dependence which is not well reproduced by the theoretical predictions. This discrepancy could be an incorrect description of the η-p interaction in the models. (author). 48 refs., 60 figs., 15 tabs

CULTURAL-ECOLOGICAL THEORY AND THE LANGUAGE EDUCATION OF ROMA CHILDREN

2017-12-01

Full Text Available The paper presents results from language testing of 70 Roma children from Bulgaria - pupils of grade 1, studying in one of the biggest Roma settlement’s schools in Sofia, “Fakulteta” district. The children were tested using the Peabody Picture Vocabulary Test. The test measures language comprehension and language production of the children at the beginning and end of the school year. Between the first and second testing, the teaching methodology in instruction for the children was changed - a Roma assistant teacher whose task was to use the mother tongue of the children as a communicative tool was introduced to the classes. The results of the children during the second testing were substantially better and they are discussed in the light of the theory of the American anthropologist J. Ogbu, who developed his cultural-ecological theory (CE in the 1980s. The results of the children are analyzed via dispersion analysis using ANOVA. According to Ogbu’s CE theory, the school success of minority children depends on the attitudes of the society at large and the level of community support. The paper also briefly discusses the reason why the de-segregation of the Roma children and their integration into mainstream schools in Bulgaria has largely proved to be a failure.

Full Text Available Abstract Background Leadership style and specific organizational climates have emerged as critical mechanisms to implement targeted practices in organizations. Drawing from relevant theories, we propose that climate for implementation of cultural competence reflects how transformational leadership may enhance the organizational implementation of culturally responsive practices in health care organizations. Methods Using multilevel data from 427 employees embedded in 112 addiction treatment programs collected in 2013, confirmatory factor analysis showed adequate fit statistics for our measure of climate for implementation of cultural competence (Cronbach’s alpha = .88 and three outcomes: knowledge (Cronbach’s alpha = .88, services (Cronbach’s alpha = .86, and personnel (Cronbach’s alpha = .86 practices. Results Results from multilevel path analyses indicate a positive relationship between employee perceptions of transformational leadership and climate for implementation of cultural competence (standardized indirect effect = .057, bootstrap p < .001. We also found a positive indirect effect between transformational leadership and each of the culturally competent practices: knowledge (standardized indirect effect = .006, bootstrap p = .004, services (standardized indirect effect = .019, bootstrap p < .001, and personnel (standardized indirect effect = .014, bootstrap p = .005. Conclusions Findings contribute to implementation science. They build on leadership theory and offer evidence of the mediating role of climate in the implementation of cultural competence in addiction health service organizations.

In the 1960’s she coined the term culturally congruent care, which is the primary goal of Transcultural nursing practice. Recently, there is a noticeable increase in the usage of the advanced hospitals’ health services by the Bedouin; as their awareness developed in term of health issues, and this put the health care providers (especially nurses in a great chance to face this Bedouin’s culture in clinical areas. So we have to enrich our understanding of the Bedouin’s culture to deliver a culturally congruent and satisfying care. A personal experience of two oncology nurses in working with a female patient with breast cancer and her Bedouin family described, with application of Madeleine Leininger’s theory of culture care diversity and universality. Concluding that understanding, considering and valuing cultural differences when delivering nursing care are vital to ensure providing a culturally congruent nursing care as well as avoid conflicts.

Lignin, a natural macromolecular compound, plays an important role in the texture and taste of fruit. Hard end is a physiological disorder of pear fruit, in which the level of lignification in fruit tissues is dramatically elevated. Cinnamyl alcohol dehydrogenase and expansin genes (PpCAD2 and PpEXP2, respectively) exhibit higher levels of expression in 'Whangkeumbae' (Pyrus pyrifolia) pear fruit exhibiting this physiological disorder, relative to control fruit without symptoms. These genes were isolated from pear fruit and subsequently expressed in tobacco (Nicotiana tabacum) to investigate their function. Histochemical staining for lignin revealed that the degree of lignification in leaf veins and stem tissues increased in plants transformed with sense constructs and decreased in plants transformed with antisense constructs of PpCAD2. The expression of native NtCADs was also inhibited in the antisense PpCAD2 transgenic tobacco. Sense and antisense PpCAD2 transgenic tobacco exhibited an 86.7% increase and a 60% decrease in CAD activity, respectively, accompanied by a complementary response in lignin content in root tissues. The basal portion of the stem in PpEXP2 transgenic tobacco was bent and highly lignified. Additionally, the level of cellulose also increased in the stem of PpEXP2 transgenic tobacco. Collectively, these results suggested that PpCAD2 and PpEXP2 genes play a significant role in lignin accumulation in transgenic tobacco plants, and it is inferred that these two genes may also participate in the increased lignification observed in hard end pear fruit.

Interculturality may be something normal which everyone possesses to a degree. However, dominant neo-essentialist theories of culture give the impression that we are too different to easily cross-cultural boundaries. These theories support the development of academic disciplines and the need for professional certainty in intercultural training.…

IMPLICITE THEORIES OF CREATIVITY: CROSS-CULTURAL STUDY

Milos Kankaras

Full Text Available In this work we analyzed laypersons’ implicit theories of creativity in twodifferent national cultures: Serbia (N=257 and the United States of America(N=255. Relying on previous works in this field, we have constructed aquestionnaire comprised of 52 indicative and 36 contra-indicative personalcharacteristic which were rated by respondents on a 5-point scale on criteria of theircreativity and desirability. Results show that both groups have similar conceptionsof a creative person, which they see as an energetic, self-confident individual, giftedwith creative talents and exceptional intellectual abilities, with profoundemotionality and brightness. The main difference between the two groups is thatrespondents from Serbia, contrary to their American counterparts, do not perceivecharacteristics which reflect obedience to social norms as a contra-indication tocreativity. Respondents have mostly seen creative attributes as desirable, althoughthere is a number of characteristics that are rated differently in terms of theircreativity and desirability. These results confirm that creativity and desirability aretwo distinct concepts and indicate positive view of creativity as a phenomenon andcreative person as such.

Exploring Formative Assessment Using Cultural Historical Activity Theory

Full Text Available Formative assessment is a pedagogic practice that has been the subject of much research and debate, as to how it can be used most effectively to deliver enhanced student learning in the higher education setting. Often described as a complex concept it embraces activities that range from facilitating students understanding of assessment standards, to providing formative feedback on their work; from very informal opportunities of engaging in conversations, to the very formal process of submitting drafts of work. This study aims to show how cultural historical activity theory can be used as a qualitative analysis framework to explore the complexities of formative assessment as it is used in higher education. The original data for the research was collected in 2008 by semi structured interviews and analysed using a hermeneutic phenomenological approach. For this present paper three selected transcripts were re-examined, using a case study approach that sought to understand and compare the perceptions of five academic staff, from three distinct subject areas taught within a UK university. It is proposed that using activity theory can provide insight into the complexity of such experiences, about what teachers do and why, and the influence of the community in which they are situated. Individually the cases from each subject area were analysed using activity theory exploring how the mediating artefacts of formative assessment were used; the often implicit rules that governed their use and the roles of teachers and students within the local subject community. The analysis also considered the influence each aspect of the unit of activity had on the other in understanding formative assessment practice. Subsequently the three subject cases were compared and contrasted. The findings illuminate a variety of practices, including how students and staff engage together in formative assessment activities and for some, how dialogue is used as one of the key tools

The linearity of the chains confers to iPP, low melt strength, which means a low strength to stretching during elongation. The increase of melt strength and the extensibility is due to the increase of the entanglement of the macromolecules chains. The HMS-PP (high melt strength polypropylene) was synthesized (based on the grains iPP) through gamma irradiation in the iPP under acetylene atmosphere followed by heat treatment for recombination and subsequent annihilation of the other free radicals. Samples of HMS-PP and iPP were subjected to environmental aging in IPEN - Sao Paulo and in the QUV chamber. The results show fractured surfaces of iPP and HMS-PP that are intensified with exposure time. The iPP degradation process has the predominance of chain scissions, with carbonyl and hydroperoxides formation which act as initiators of photo degradation mechanisms. (author)

Drought is a major abiotic stress that causes the yearly yield loss of maize, a crop cultured worldwide. Breeding drought-tolerant maize cultivars is a priority requirement of world agriculture. Clade A PP2C phosphatases (PP2C-A), which are conserved in most plant species, play important roles in abscisic acid (ABA) signaling and plant drought response. However, natural variations of PP2C-A genes that are directly associated with drought tolerance remain to be elucidated. Here, we conducted a candidate gene association analysis of the ZmPP2C-A gene family in a maize panel consisting of 368 varieties collected worldwide, and identified a drought responsive gene ZmPP2C-A10 that is tightly associated with drought tolerance. We found that the degree of drought tolerance of maize cultivars negatively correlates with the expression levels of ZmPP2C-A10. ZmPP2C-A10, like its Arabidopsis orthologs, interacts with ZmPYL ABA receptors and ZmSnRK2 kinases, suggesting that ZmPP2C-A10 is involved in mediating ABA signaling in maize. Transgenic studies in maize and Arabidopsis confirmed that ZmPP2C-A10 functions as a negative regulator of drought tolerance. Further, a causal natural variation, deletion allele-338, which bears a deletion of ERSE (endoplasmic reticulum stress response element) in the 5'-UTR region of ZmPP2C-A10, was detected. This deletion causes the loss of endoplasmic reticulum (ER) stress-induced expression of ZmPP2C-A10, leading to increased plant drought tolerance. Our study provides direct evidence linking ER stress signaling with drought tolerance and genetic resources that can be used directly in breeding drought-tolerant maize cultivars.

Suomen Malmi Oy (Smoy) core drilled eighteen drillholes to survey the ground and bedrock conditions in the encapsulation plant building site at Olkiluoto, Eurajoki 2011. Soil quality, bedrock depth and quality of near surface bedrock were investigated in this project. The drillholes were drilled between 19th of October and 8th of November 2011. The lengths of the drillholes are mostly between 7 to 9 metres, except for the drillhole OL-PP79, which is 15 metres by length. The drillholes are 76 mm by diameter, and the core diameter is 60.2 mm. The lightweight GM75 drilling rig with rubber tracks was used. The drilling water was taken from the ONKALO area research building freshwater pipeline and sodium fluorescein was added as a label agent in the drilling water. The drillholes were not left open. In addition to drilling the drillcores were logged and reported by geologist. Geological logging included the following parameters: lithology, foliation, fracture parameters, fractured zones, core loss, weathering, fracture frequency, RQD and rock quality. The average natural fracture frequencies of the drillcores range from 2.5 pc/m (OL-PP77) to 11.8 pc/m (OL-PP86). The average RQD ranges from 55.1 % (OL-PP86) to 96.4 % (OL-PP77). The penetrated soils are mostly ground fill (blast rock), but some clays and sands are lying below the fill layer. (orig.)

Measurements of the differential cross sections of the pp -> pp pi sup 0 reaction at 310, 320, 340, 360, 400 and 425 MeV have been carried out at the CELSIUS storage ring in Uppsala. An attempt has been made to describe the distributions obtained in terms of the five partial waves Ss, Ps, Pp, Sd and Ds. The relative contributions from the different states depend significantly upon the energy. For instance, that of the Ss state drops from about 80% at 310 MeV to around 10% at 425 MeV.

The aim of this research is to study the relationship between compatibilizer and yield strength of polylactic acid (PLA) and polypropylene (PP) blend. The PLA is blended with PP (PLA/PP) at the ratios of 70/30, 50/50 and 30/70. In addition, (1) polypropylene grafted maleic anhydride (PP-g-MAH) as a compatibilizer at 0.3 and 0.7 part per hundred of PLA/PP resin (phr) and (2) dicumyl peroxide (DCP) being an initiator at 0.03 and 0.07 phr are added in each composition. Yield strength is characterized to study the interaction between compatibilizer, initiator and yield strength by using experimental design of multilevel full factorial. The results show that (1) the yield strength of PLA/PP blend are increased after addition of compatibilizer. Because the adding of PP-g-MAH and DCP resulted in improving compatibility between PLA and PP. (2) there are interaction between PP-g-MAH and DCP that have affected the final properties of PLA/PP blend. The highest yield strength of 27.68 MPa is provided at the ratio of 70/30 blend by using the 0.3 phr of PP-g-MAH and 0.03 phr of DCP. Linear regression model is fitted and follow the assumptions of normal distribution.

Geertz versus Levi-Strauss: latent structural dispositions in Geertz "theory of culture"?

Directory of Open Access Journals (Sweden)

Gordana Gorunović

2016-02-01

Full Text Available These are two authors, in Foucauldian terms that certainly belong to the most influential individuals in socio-cultural anthropology, as well as in the social sciences and interdisciplinary research more broadly. Claude Levi- Strauss became some kind of an "intellectual hero" during the domination of structuralism in the mid-twentieth century and during the 1960s, while Clifford Geertz was an ‘icon and ambassador’ of anthropology in the second half of the twentieth century. They are both one of the founders of the discourse theory. They not only established a distinct theoretical approaches and methods – structural (Levi-Strauss and interpretative anthropology (Clifford Geertz, but through their intellectual authority they also inspired paradigms and intellectual movements making structuralism and "interpretation of culture" more than some passing episodes in the history of social though (in terms of "trendy ideas". My aim is to make some parallels between these two authors, who despite all the differences that are evident in their epistemological discourses, theoretical approaches and methods (as well as in their ethnographic and anthropological writings itself still have some similarities in their theorisation and interpretation of culture, which I would like to stress in this paper.

A fungal strain, Penicillium sp. AZ, produced the azaphilone Monascus pigment homolog when cultured in a medium composed of soluble starch, ammonium nitrate, yeast extract, and citrate buffer, pH 5.0. One of the typical features of violet pigment PP-V [(10Z)-12-carboxyl-monascorubramine] is that pyranoid oxygen is replaced with nitrogen. In this study, we found that ammonia and nitrate nitrogen are available for PP-V biosynthesis, and that ammonia nitrogen was much more effective than nitrate nitrogen. Further, we isolated nitrate assimilation gene cluster, niaD, niiA, and crnA, and analyzed the expression of these genes. The expression levels of all these genes increased with sodium nitrate addition to the culture medium. The results obtained here strongly suggest that Penicillium sp. AZ produced PP-V using nitrate in the form of ammonium reduced from nitrate through a bioprocess assimilatory reaction.

Franz Serafin Exner's Indeterminist Theory of Culture

Science.gov (United States)

Stöltzner, Michael

By combining Ernst Mach's empiricism, Ludwig Boltzmann's atomism, and the relative frequency interpretation of probability, the Viennese physicist Franz Serafin Exner argued long before quantum mechanics that the basic laws of nature were of indeterministic nature and that the strict deterministic laws found on the macroscopic scale obtained in the limit of very many random events. The number of single events studied in humanistic disciplines was at best sufficient to ascertain weak regularities. But both science and the humanities were grounded in the law of large numbers, such that the world as a whole was governed by a global tendency towards the most probable state. Exner's unified outlook was not reductionist; rather it resembled the unification intended by Alexander von Humboldt's physical description of the world. Moreover, to Exner's lights, even culture was a natural product supervening on the various rising and declining peoples that exhibited a continuous ethical progress and the development of an objective scientific world view. By separating the individual microscopic and the ideal macroscopic levels, Exner's indeterminist theory simultaneously opposed the Spenglerian challenge against science and embraced his criticism of civilization and the death of the arts.

Displacement affinity chromatography of protein phosphatase one (PP1 complexes

Directory of Open Access Journals (Sweden)

Gourlay Robert

2008-11-01

Full Text Available Abstract Background Protein phosphatase one (PP1 is a ubiquitously expressed, highly conserved protein phosphatase that dephosphorylates target protein serine and threonine residues. PP1 is localized to its site of action by interacting with targeting or regulatory proteins, a majority of which contains a primary docking site referred to as the RVXF/W motif. Results We demonstrate that a peptide based on the RVXF/W motif can effectively displace PP1 bound proteins from PP1 retained on the phosphatase affinity matrix microcystin-Sepharose. Subsequent co-immunoprecipitation experiments confirmed that each identified binding protein was either a direct PP1 interactor or was in a complex that contains PP1. Our results have linked PP1 to numerous new nuclear functions and proteins, including Ki-67, Rif-1, topoisomerase IIα, several nuclear helicases, NUP153 and the TRRAP complex. Conclusion This modification of the microcystin-Sepharose technique offers an effective means of purifying novel PP1 regulatory subunits and associated proteins and provides a simple method to uncover a link between PP1 and additional cellular processes.

Studies on the properties of rice-husk-filled-PP composites: effect of maleated PP

Full Text Available Rice husk is a by-product of rice milling process that usually finds inadequate final disposal (burning, land filling. Thermoplastics composites filled with rice husk flour are materials that offer an alternative for using this agricultural resource viewing the production of low dense materials with some specific properties. In this work composites of polypropylene (PP and rice husk flour (RHF were prepared by melt extrusion. Maleic anhydride-modified PP (MAPP was added as a coupling agent. It was verified that tensile strength decreased with filler loading. The presence of MAPP improved this property showing a strong dependence on the MAPP/RHF ratio (MAPP/RHF = 0.03 produced the best results. The density of the composites slightly increased with filler and coupling agent in comparison to pure PP. The presence of MAPP diminished more than 20% water uptake in highly-loaded composites.

Electron Spin Resonance studies on PS, PP and PS/PP blends under gamma irradiation

Complete text of publication follows. Electron Spin Resonance (ESR) studies on Polystyrene (PS), Polypropylene (PP) and their mixtures at compositions of 80/20 with and without a compatibilizer (SBS in block), 7.5 wt.%, irradiated with gamma rays from a Cobalt-60 source with a dose rate of 4.8 KGy/h at integral doses of radiation of 10, 25, 50, 60, 70, 400, 800 and 1300 KGy in the presence of air and at room temperature (RT) are reported. The dependence of resonance line width, Hpp; resonance line shapes K, and radical concentration, S, with the integral dose of irradiation is investigated. The nature of the free radicals after ten days of air storage is discussed. The free radical concentration, the double integral of the resonance line, S, has been estimated at room temperature, RT, for a group of single lines, characterized by the same giromagnetic, g, value by direct numerical double integration. In the samples studied no spectrum of 0 kGy of integral dose was observed. The concentration of radicals, S, observed when the integral radiation doses was increased, presents a maximum value in the PP samples at high doses (70-1300 kGy) and minimum values in the PS samples with the same doses. This shows that the PP degrades at a faster rate than the PS, owing to the presence of the bencenic ring in the latter. In the PS/PP mixtures studied with and without compatibilizer, the values of the radical concentration is found between the observed values in the homopolymers, being closer to the PS, which might imply that the presence of PS decays the degradation process of the PP in the mixture

Theory of Queer Identities: Representation in Contemporary East-European Art and Culture

Saša Kesić

2017-10-01

Full Text Available Starting from the general theory of identity, gender theory, queer theory and theory of bio/necropolitics, as theoretical platforms, in a few case studies I will analyze the Pride Parade as a form of manifestation of gender body and queer body representations in visual arts, and gender and queer body representations in mass media. My hypothesis is that the key for understanding the chosen case studies is in understanding the relation between their aesthetics, political and social interventions. This will consider political involvement, social injustice, alienation, stereotypes on which ideological manipulations are based etc., as well as the creative strategies used for moving the borders of visual art in searching for authentically-performed creative expressions and engagements. In the time we live it is necessary for the politicization of art to use queer tactics, which work as political strategies of subversion of every stable structure of power. Queer tactics, in my opinion, are weapons in disturbance of the stable social mechanisms, which every power tries to establish and perform over any ‘mass’, in order to transform it to race, gender, tribe, nation or class.   Article received: June 6, 2017; Article accepted: June 20, 2017; Published online: October 15, 2017; Original scholarly paper How to cite this article: Kesić, Saša.

Study on GIF PR/PP evaluation methodology

Energy Technology Data Exchange (ETDEWEB)

Lee, B. H.; Kwon, E. H.; Kim, H. D. [KAERI, Daejeon (Korea, Republic of)

2012-10-15

Proliferation resistance (PR) and physical protection (PP) is one of the four technology goals of generation IV nuclear energy systems (NESs). The PR component of the goal focuses on providing strong assurance that generation IV NESs are the least desirable sources for the diversion or undeclared production of nuclear materials, whereas the PP portion of the goal ensures that generation IV NESs are robust against theft and sabotage. In 2002, the road map of the Generation IV International Forum (GIF) envisioned that the R and D program for PR and PP would have three areas: 1) safeguards and physical protection technology R and D for each GIF system; 2) formulation of PR and PP criteria and metrics; and 3) evaluation of the criteria and metrics. To cover these R and D items, the PR and PP Working Group (PRPPWG) was formed in late 2002 and has since developed a methodology for PR and PP evaluation. In a succession of revisions beginning in 2004, consensus was achieved amongst all participating GIF countries and related organizations (i.e., IAEA and EU), and Revision 6 of the methodology report was approved by GIF for open distribution in 2011. The paper describes in detail the methodology developed by the PRPPWG and discusses its applicability to the sodium-cooled fast reactor (SFR) fuel cycle with pyro processing currently under development in Korea.

The description and interpretation of material culture may be regarded as the essence of archaeology, a discipline that seeks to recover, describe, document, and interpret past human culture. More recently, understanding that actions occur in a material world that is constituted symbolically, archaeological explanations are often framed in sociocultural meanings, the analysis of agencies, practices and behaviors. I shall subsequently return to this issue. Because of their longevity in the archaeological record, lithic and ceramic artifacts are crucial to the endeavor to interpret human culture. Objects fashioned from clay and subjected to intentional artificial sources of heat made their initial appearance in the archaeological record more than 26.000 years ago. Ceramic objects have been created in a seemingly endless variety of shapes and forms, varying from fertility figurines. to cooking and food storage vessels. lamps, smoking pipes, medicinal pastilles, tokens, beehives, and coffins to modern whitewares and pyroceramics.

We study the sensitivity of pion interferometry in pp and anti pp collisions at ISR energies to the resonance abundance. We show that those data are not compatible with the full resonance fractions predicted by the Lund model. The preliminary S+S and O+Au data at 200 A GeV are, however, not incompatible with the Lund predictions, although their sensitivity to resonances is significantly weaker than in the pp/anti pp case.

Seawater has occupied an ambiguous place in anthropological categories of "nature" and "culture." Seawater as nature appears as potentiality of form and uncontainable flux; it moves faster than culture - with culture frequently figured through land-based metaphors - even as culture seeks to channel water's (nature's) flow. Seawater as culture manifests as a medium of pleasure, sustenance, travel, disaster. I argue that, although seawater's qualities in early anthropology were portrayed impressionistically, today technical, scientific descriptions of water's form prevail. For example, processes of globalization - which may also be called "oceanization" - are often described as "currents," "flows," and "circulations." Examining sea-set ethnography, maritime anthropologies, and contemporary social theory, I propose that seawater has operated as a “theory machine” for generating insights about human cultural organization. I develop this argument with ethnography from the Sargasso Sea and in the Sea Islands. I conclude with a critique of appeals to water's form in social theory.

Effects of thermal ageing on HMS-PP crystallinity

Oliani, Washington L.; Parra, Duclerc F.; Lima, Luis F.C.P.; Lugao, Ademar B.

The isotactic polypropylene is a linear polymer which exhibits low melt strength. Irradiation of PP under inert atmosphere causes a combination of chain scissioning and long-chain branching, and results in a material with significant enhanced melt strength. This process, which is sometimes termed visbreaking, thus provides improvement of rheological properties. HMS-PP (High Melt Strength Polypropylene) was obtained by the irradiation in atmosphere of acetylene as crosslinker agent. It was employed doses of 12.5 and 20 kGy of gamma radiation. The objective of this study is to investigate the effects of thermal ageing on the crystallinity level and chemical structure of HMS-PP. The thermal stability of the HMS-PP was evaluated after thermal ageing of samples using a stove at temperature of 90 deg C, in presence of air at different periods of time. The samples submitted to the thermal ageing were characterized by: thermogravimetry (TGA), differential scanning calorimetry (DSC), infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Since the long-term engineering properties of HMS-PP are intrinsically linked with the polymer microstructure, there is significant interest in understanding the effects of ageing, particularly due to prolonged exposure at service temperatures. In thermo-oxidative conditions, the formation of the oxidation products essentially involves a hydrogen abstraction by the peroxyl radicals, leading to hydroperoxides as primary products and chemical degradation in the immediate crack tips. Oxidative degradation on the network of HMS-PP, created by radiation process of PP, was revealed by the analytical results showing the susceptibility of HMS-PP to thermal oxidative degradation. Yellowing of the samples surface and oxidative products of degradation among other evidences were observed. (author)

Leadership style and specific organizational climates have emerged as critical mechanisms to implement targeted practices in organizations. Drawing from relevant theories, we propose that climate for implementation of cultural competence reflects how transformational leadership may enhance the organizational implementation of culturally responsive practices in health care organizations. Using multilevel data from 427 employees embedded in 112 addiction treatment programs collected in 2013, confirmatory factor analysis showed adequate fit statistics for our measure of climate for implementation of cultural competence (Cronbach's alpha = .88) and three outcomes: knowledge (Cronbach's alpha = .88), services (Cronbach's alpha = .86), and personnel (Cronbach's alpha = .86) practices. Results from multilevel path analyses indicate a positive relationship between employee perceptions of transformational leadership and climate for implementation of cultural competence (standardized indirect effect = .057, bootstrap p climate in the implementation of cultural competence in addiction health service organizations.

On the Connection between Kinetic Monte Carlo and the Burton-Cabrera-Frank Theory

Patrone, Paul; Margetis, Dionisios; Einstein, T. L.

2013-03-01

In the many years since it was first proposed, the Burton- Cabrera-Frank (BCF) model of step-flow has been experimentally established as one of the cornerstones of surface physics. However, many questions remain regarding the underlying physical processes and theoretical assumptions that give rise to the BCF theory. In this work, we formally derive the BCF theory from an atomistic, kinetic Monte Carlo model of the surface in 1 +1 dimensions with one step. Our analysis (i) shows how the BCF theory describes a surface with a low density of adsorbed atoms, and (ii) establishes a set of near-equilibrium conditions ensuring that the theory remains valid for all times.

Advancing institutional anomie theory: a microlevel examination connecting culture, institutions, and deviance.

Muftić, Lisa R

2006-12-01

Institutional anomie theory (IAT) contends that crime can be explained by an examination of American society, particularly the exaggerated emphasis on economic success inherent in American culture, which has created a "cheating orientation" that permeates structural institutions, including academia. Consistent with its macrosocial perspective, previous tests of IAT have examined IAT variables at the structural level only. The current study tests the robustness of IAT by operationalizing IAT variables at the individual level and looking at a minor form of deviance, student cheating. The author also examines the role statistical modeling has in testing the theory at the microlevel. Undergraduates, 122 American born and 48 international, were surveyed about their cheating behaviors and adherence to economic goal orientations. Results related to the hypothesis that American students, relative to foreign-born students, will have an increased adherence to economic goal orientations that increase cheating behaviors are presented, as are suggestions for future studies.

This article describes the development of a dynamic culturally constructed clinical practice model for HIV/STI prevention, the Narrative Intervention Model (NIM), and illustrates its application in practice, within the context of a 6-year transdisciplinary research program in Mumbai, India. Theory and research from anthropology, psychology, and public health, and mixed-method ethnographic research with practitioners, patients, and community members, contributed to the articulation of the NIM for HIV/STI risk reduction and prevention among married men living in low-income communities. The NIM involves a process of negotiation of patient narratives regarding their sexual health problems and related risk factors to facilitate risk reduction. The goal of the NIM is to facilitate cognitive-behavioral change through a three-stage process of co-construction (eliciting patient narrative), deconstruction (articulating discrepancies between current and desired narrative), and reconstruction (proposing alternative narratives that facilitate risk reduction). The NIM process extends the traditional clinical approach through the integration of biological, psychological, interpersonal, and cultural factors as depicted in the patient narrative. Our work demonstrates the use of a recursive integration of research and practice to address limitations of current evidence-based intervention approaches that fail to address the diversity of cultural constructions across populations and contexts.

On the basis of self-determination theory (R. M. Ryan & E. L. Deci, 2000) and cultural descriptions drawn from H. C. Triandis (1995), the authors hypothesized that (a) individuals from different cultures internalize different cultural practices; (b) despite these differences, the relative autonomy of individuals' motivation for those practices predicts well-being in all 4 cultures examined; and (c) horizontal practices are more readily internalized than vertical practices across all samples. Five hundred fifty-nine persons from South Korea, Russia, Turkey and the United States participated. Results supported the hypothesized relations between autonomy and well-being across cultures and gender. Results also suggested greater internalization of horizontal relative to vertical practices. Discussion focuses on the distinction between autonomy and individualism and the relative fit of cultural forms with basic psychological needs.

Long-Term Culture of Self-renewing Pancreatic Progenitors Derived from Human Pluripotent Stem Cells

2017-06-01

Full Text Available Pluripotent stem cells have been proposed as an unlimited source of pancreatic β cells for studying and treating diabetes. However, the long, multi-step differentiation protocols used to generate functional β cells inevitably exhibit considerable variability, particularly when applied to pluripotent cells from diverse genetic backgrounds. We have developed culture conditions that support long-term self-renewal of human multipotent pancreatic progenitors, which are developmentally more proximal to the specialized cells of the adult pancreas. These cultured pancreatic progenitor (cPP cells express key pancreatic transcription factors, including PDX1 and SOX9, and exhibit transcriptomes closely related to their in vivo counterparts. Upon exposure to differentiation cues, cPP cells give rise to pancreatic endocrine, acinar, and ductal lineages, indicating multilineage potency. Furthermore, cPP cells generate insulin+ β-like cells in vitro and in vivo, suggesting that they offer a convenient alternative to pluripotent cells as a source of adult cell types for modeling pancreatic development and diabetes.

Yet a common seductive vision of planning is mirrored by utopian claims for cyberculture, which often fall short of the hoped-for reality. We suggest that one problem is the linear thinking common to mainstream planning and digital thinking, which leads to a cumulative lack of fit with the non-linear (chaotic world of social action. We draw on chaos and complexity theory to reframe planning problems and develop more creative digital strategies in a specific location, Western Sydney, using and adapting Geographic Information Systems.

Perigee: Zero, a Unified Theory of Cultural Heritage and Geological History

Science.gov (United States)

Davias, M. E.

2006-05-01

Perigee: Zero proposes a unified theory to solve enigmas haunting our cultural heritage and the Earth's geological history. We maintain the theory is simple and provable. We document the terraforming of the Earth by the cratering and accretive action of impacting comets and resulting ejecta, during events occurring at regular intervals over the past 15,000 years. Visual evidence of geomorphed landscape is presented using the perspective of high-resolution satellite imaging and DEM data. Correlation of these images with physical and historic evidence has proven supportive. Sections of the lithosphere have been lofted thousands of kilometers. Excised trenches have filled with water, or left as barren desert. Blankets of ejecta have overlain the continents and their inhabitants. The atmosphere was disrupted by the influx of dust and energy. Composed of hydrated silica, the comets have added a significant percentage of the water and unusually pure silicate (as sand and clay) now present on earth. Human history is immersed in these events. Oral and written works comprising much of the world's cultural heritage provide us with accounts of catastrophic damage visited upon Earth and its inhabitants. Those accounts describe mountains being moved, large expanses of the earth being swept clean - or replaced with open ocean, civilizations buried, years of darkness, the world flooded. Our forefathers invoked deities from the heavens, or perhaps giant kangaroos. We invoke impactors from the Taurid Complex, a simple and natural process, as most of its progenitor's mass may be missing. The damage to the earth is interpreted as the result of hundreds of grazing and nearly tangential impacts, suggesting decaying orbits of earth-captured cosmic bodies as a plausible solution. The events are seen occurring when the low point of the orbit -the perigee- reaches the earth's surface; in effect Perigee: Zero.

Using cultural-historical activity theory to analyze social service practices evolving from the Norwegian HUSK projects.

Science.gov (United States)

Foot, Kirsten

2015-01-01

The HUSK projects catalyzed innovation in the practices of providing social services that could yield useful insights both within and outside of Norway if analyzed in these two ways: (a) retrospective analysis of the development of individual HUSK projects in light of their cultural-historical contexts, and (b) comparative analysis of the efforts to advance multi-sector collaboration in some of the HUSK projects. Such analyses require a practice-based research approach that takes into account culture and history. In this article the author explains how cultural-historical activity theory provides such an approach, illustrated via several HUSK cases. The author suggests five questions for future analyses of the HUSK projects and argues that insights gleaned from such analyses could contribute significantly to research on-and the provision of-social services.

Bringing culture to basic psychological theory--beyond individualism and collectivism: comment on Oyserman et al. (2002).

Science.gov (United States)

Miller, Joan G

2002-01-01

D. Oyserman, H. M. Coon, and M. Kemmelmeir (2002) offered a comprehensive literature review on individualism and collectivism that forwards valuable suggestions for ways to enhance future research conducted within this framework. The author argues that although their criticisms of much contemporary social psychological research on individualism and collectivism are valid, even more fundamental problems need to be recognized as characterizing work within this tradition, such as the insufficiently subtle nature of the views held of culture, the limited attention given to meanings, and the downplaying of contextual variation. The author suggests adopting more nuanced and process-oriented conceptions of culture and more contextually grounded views of its impact on psychological functioning as a way of realizing the promise of cultural psychology to broaden and provide insight into basic psychological theory.

[Colors and their meaning in culture and psychology--a historical outline and contemporary status of color vision theories].

Grzybowski, Andrzej; Lewicka, Romana; Torlińska, Teresa; Stelcer, Bogusław

2008-01-01

The mechanism of color perception has intrigued scholars from antiquity. However, the understanding of this phenomena only came with the recognition of the nature of light and visual perception. Ancient concepts, present in science until the Renaissance, were based more on philosophical considerations and theoretical speculations than on anatomical studies and a matter-of-fact assessment of physiological functions of the visual system. From antiquity to 17th century scientific approach to the concept of vision was dominated by two theories: intromission and extramission (emanation). Intromission theory, propagated by Alhazen (lbn al.-Haythama), Vitello, John Peckham, Roger Bacon and Leonardo da Vinci, assumed that the light was transmitted from the observed object perpendicularly to the transparent eye structures. Johannes Kepler was the first scholar to propose that the retina was the receptive part of the eye. In the first half of the 17th century, Kepler's groundbreaking optical achievements and anatomical discoveries of many other scientists cast new light on the understanding of the role of different eye structures, finally wiping out the intromission theory. A further major achievement contributing to the recognition of the true nature of colors was a theory presented by Newton in 1688. He argued that they were colored rays, and not white light, that were composed of homogenous and pure light. It was, however, not until the 19th century when two modern theories of color appeared, i.e. a trichromatic theory mostly associated with the names of Young and Hemlholtz, and an opponent colors theory of Hering. In the 20th century, the two theories--previously assumed as contradictory--were joined into the zone theories of color vision. Colors have their cultural and social meanings, as far as a very individual and personal interpretation. In the former function they are used to illustrate some cultural and sociological phenomena; in the latter, they are helpful in

Phase separation of DMDBS from iPP, and controlled crystalline orientation

Science.gov (United States)

Sreenivas, K.; Kumaraswamy, Guruswamy; Basargekar, R. S.

2012-02-01

We report an unexpected dependence of DMDBS phase separation temperature on the molecular weight of the matrix isotactic polypropylene (iPP). DMDBS crystallizes out at lower temperatures for iPP with decreasing molecular weight (and correspondingly lower tacticity). This molecular weight dependence is unique to iPP, and is not observed for either syndiotactic PP or for random ethylene-PP copolymers. We show that thermodynamic Flory-type arguments are unable to rationalize the observed results. We also results on extrusion film casting of iPP containing DMDBS and show that flow-alignment of DMDBS networks template the orientation of PP crystals. The modulus and yield strength increase on addition of DMDBS, relative to the neat iPP. Tensile modulus and yield stress of drawn films increase with the degree of orientation, and we are able to achieve a substantial increase even at relatively low draw ratios.

Abaca fibre reinforced PP composites and comparison with jute and flax fibre PP composites

Directory of Open Access Journals (Sweden)

2007-11-01

Full Text Available Abaca fibre reinforced PP composites were fabricated with different fibre loadings (20, 30, 40, 50wt% and in some cases 35 and 45 wt%. Flax and jute fibre reinforced PP composites were also fabricated with 30 wt% fibre loading. The mechanical properties, odour emission and structure properties were investigated for those composites. Tensile, flexural and Charpy impact strengths were found to increase for fibre loadings up to 40 wt% and then decreased. Falling weight impact tests were also carried out and the same tendency was observed. Owing to the addition of coupling agent (maleated polypropylene -MAH-PP, the tensile, flexural and falling weight impact properties were found to increase in between 30 to 80% for different fibre loadings. When comparing jute and flax fibre composites with abaca fibre composites, jute fibre composites provided best tensile properties but abaca fibre polypropylene composites were shown to provide best notch Charpy and falling weight impact properties. Odours released by flax fibre composites were smaller than jute and abaca fibre composites.

The PP1 binding code: a molecular-lego strategy that governs specificity.

Science.gov (United States)

Heroes, Ewald; Lesage, Bart; Görnemann, Janina; Beullens, Monique; Van Meervelt, Luc; Bollen, Mathieu

2013-01-01

Ser/Thr protein phosphatase 1 (PP1) is a single-domain hub protein with nearly 200 validated interactors in vertebrates. PP1-interacting proteins (PIPs) are ubiquitously expressed but show an exceptional diversity in brain, testis and white blood cells. The binding of PIPs is mainly mediated by short motifs that dock to surface grooves of PP1. Although PIPs often contain variants of the same PP1 binding motifs, they differ in the number and combination of docking sites. This molecular-lego strategy for binding to PP1 creates holoenzymes with unique properties. The PP1 binding code can be described as specific, universal, degenerate, nonexclusive and dynamic. PIPs control associated PP1 by interference with substrate recruitment or access to the active site. In addition, some PIPs have a subcellular targeting domain that promotes dephosphorylation by increasing the local concentration of PP1. The diversity of the PP1 interactome and the properties of the PP1 binding code account for the exquisite specificity of PP1 in vivo. © 2012 The Authors Journal compilation © 2012 FEBS.

Here we describe an HPLC-based method to quantify bacterial housekeeping nucleotides and the signaling messengers ppGpp and pppGpp. We have replicated and tested several previously reported HPLC-based approaches and assembled a method that can process 50 samples in three days, thus making kinetically resolved experiments feasible. The method combines cell harvesting by rapid filtration, followed by acid extraction, freeze-drying with chromatographic separation. We use a combination of C18 IPRP-HPLC (GMP unresolved and co-migrating with IMP; GDP and GTP; AMP, ADP and ATP; CTP; UTP) and SAX-HPLC in isocratic mode (ppGpp and pppGpp) with UV detection. The approach is applicable to bacteria without the requirement of metabolic labelling with 32P-labelled radioactive precursors. We applied our method to quantify nucleotide pools in Escherichia coli BW25113 K12-strain both throughout the growth curve and during acute stringent response induced by mupirocin. While ppGpp and pppGpp levels vary drastically (40- and ≥8-fold, respectively) these changes are decoupled from the quotients of the housekeeping pool and guanosine and adenosine housekeeping nucleotides: NTP/NDP/NMP ratio remains stable at 6/1/0.3 during both normal batch culture growth and upon acute amino acid starvation.

Psychosis-proneness and neural correlates of self-inhibition in theory of mind.

Directory of Open Access Journals (Sweden)

Lisette van der Meer

Full Text Available Impaired Theory of Mind (ToM has been repeatedly reported as a feature of psychotic disorders. ToM is crucial in social interactions and for the development of social behavior. It has been suggested that reasoning about the belief of others, requires inhibition of the self-perspective. We investigated the neural correlates of self-inhibition in nineteen low psychosis prone (PP and eighteen high PP subjects presenting with subclinical features. High PP subjects have a more than tenfold increased risk of developing a schizophrenia-spectrum disorder. Brain activation was measured with functional Magnetic Resonance Imaging during a ToM task differentiating between self-perspective inhibition and belief reasoning. Furthermore, to test underlying inhibitory mechanisms, we included a stop-signal task. We predicted worse behavioral performance for high compared to low PP subjects on both tasks. Moreover, based on previous neuroimaging results, different activation patterns were expected in the inferior frontal gyrus (IFG in high versus low PP subjects in self-perspective inhibition and simple response inhibition. Results showed increased activation in left IFG during self-perspective inhibition, but not during simple response inhibition, for high PP subjects as compared to low PP subjects. High and low PP subjects showed equal behavioral performance. The results suggest that at a neural level, high PP subjects need more resources for inhibiting the self-perspective, but not for simple motor response inhibition, to equal the performance of low PP subjects. This may reflect a compensatory mechanism, which may no longer be available for patients with schizophrenia-spectrum disorders resulting in ToM impairments.

Impaired Theory of Mind (ToM) has been repeatedly reported as a feature of psychotic disorders. ToM is crucial in social interactions and for the development of social behavior. It has been suggested that reasoning about the belief of others, requires inhibition of the self-perspective. We investigated the neural correlates of self-inhibition in nineteen low psychosis prone (PP) and eighteen high PP subjects presenting with subclinical features. High PP subjects have a more than tenfold increased risk of developing a schizophrenia-spectrum disorder. Brain activation was measured with functional Magnetic Resonance Imaging during a ToM task differentiating between self-perspective inhibition and belief reasoning. Furthermore, to test underlying inhibitory mechanisms, we included a stop-signal task. We predicted worse behavioral performance for high compared to low PP subjects on both tasks. Moreover, based on previous neuroimaging results, different activation patterns were expected in the inferior frontal gyrus (IFG) in high versus low PP subjects in self-perspective inhibition and simple response inhibition. Results showed increased activation in left IFG during self-perspective inhibition, but not during simple response inhibition, for high PP subjects as compared to low PP subjects. High and low PP subjects showed equal behavioral performance. The results suggest that at a neural level, high PP subjects need more resources for inhibiting the self-perspective, but not for simple motor response inhibition, to equal the performance of low PP subjects. This may reflect a compensatory mechanism, which may no longer be available for patients with schizophrenia-spectrum disorders resulting in ToM impairments.

Full Text Available Hypertensive disorders affect about one third of all people aged 20 and above, and are treated with anti-hypertensive drugs. Preeclampsia (PE is one form of such disorders that only develops during pregnancy. It affects ten million pregnant women globally and additionally causes fetal loss and major newborn disabilities. The syndrome's origin is multifactorial, and anti-hypertensive drugs are ineffective in treating it. Biomarkers are helpful for predict its development. Generic drugs, such as low dose aspirin, were proven effective in preventing preterm PE. However, it does not cure the majority of cases and many studies are underway for fighting PE with extended use of additional generic drugs, or through new drug development programs.This review focuses on placental protein 13 (PP13. This protein is only expressed in the placenta. Impaired PP13 DNA structure and/or its reduced mRNA expression leads to lower blood PP13 level that predict a higher risk of developing PE. Two polymorphic PP13 variants have been identified: (1 The promoter PP13 variant with an “A/A” genotype in the -98 position (versus “A/C” or “C/C”. Having the “A/A” genotype is coupled to lower PP13 expression, mainly during placental syncytiotrophoblast differentiation and, if associated with obesity and history of previous preeclampsia, it accurately predicts higher risk for developing the disorder. (2 A thymidine deletion at position 221 causes a frame shift in the open reading frame, and the formation of an early stop codon resulting in the formation of DelT221, a truncated variant of PP13. In pregnant rodents, both short- and long- term replenishment of PP13 causes reversible hypotension and vasodilation of uterine vessels. Long-term exposure is also accompanied by the development of larger placentas and newborns. Also, only w/t PP13 is capable of inducing leukocyte apoptosis, providing maternal immune tolerance to pregnancy.Based on published data, we

The purpose of this study was to generate a substantive model that accounts for the explanatory social processes of communication in which nurses were engaged in clinical settings in Korea. Grounded theory methodology was used in this study. A total of 15 clinical nurses participated in the in-depth interviews. "Assimilating to the hierarchical culture" emerged as the basic social process of communication in which the participants engaged in their work environments. To adapt to the cultures of their assigned wards, the nurses learned to be silent and engaged in their assimilation into the established hierarchy. The process of assimilation consisted of three phases based on the major goals that nurses worked to achieve: getting to know about unspoken rules, persevering within the culture, and acting as senior nurse. Seven strategies and actions utilized to achieve the major tasks emerged as subcategories, including receiving strong disapproval, learning by observing, going silent, finding out what is acceptable, minimizing distress, taking advantages as senior nurse, and taking responsibilities as senior nurse. The findings identified how the pattern of communication in nursing organizations affected the way in which nurses were assimilated into organizational culture, from individual nurses' perspectives. In order to improve the rigid working atmosphere and culture in nursing organizations and increase members' satisfaction with work and quality of life, managers and staff nurses need training that focuses on effective communication and encouraging peer opinion-sharing within horizontal relationships. Moreover, organization-level support should be provided to create an environment that encourages free expression.

Exclusive channels in bar pp annihilation at rest provide a powerful tool for studying the meson spectrum below the bar pp threshold. The mesons can be classified in SU(3) multiplets according to their quantum numbers. The states which do not fit into this classification are candidates for new forms of hadronic matter like glueballs, hybrids, and multi-quark states. Recent results on the search for exotic states in exclusive channels of bar pp annihilation at rest are discussed. No less important is the study of the annihilation mechanism. In particular, high-statistic measurements of bar pp annihilation at rest into two-meson final states are an excellent tool for studying quark dynamics. Examples of two-body reactions are presented. 24 refs., 9 figs., 3 tabs

Polypropylene (PP) is a biocompatible and biostable polymer, showing good mechanical properties that has been recently introduced in the biomedical field for bone repairing applications; however, its poor surface properties due to its low surface energy limit their use in biomedical applications. In this work, we have studied the topographical modification of polypropylene (PP) laser textured with Nd:YVO4 nanosecond lasers emitting at λ = 1064 nm, 532 nm, and 355 nm. First, optical response of this material under these laser wavelengths was determined. The application of an absorbing coating was also studied. The influence of the laser processing parameters on the surface modification of PP was investigated by means of statistically designed experiments. Processing maps to tailor the roughness, and wettability, the main parameters affecting cell adhesion characteristics of implants, were also determined. Microhardness measurements were performed to discern the impact of laser treatment on the final mechanical properties of PP.

ONE OF THE MOST ESSENTIAL BUT THEORETICALLY VEXING ISSUES REGARDING THE NOTION OF CULTURE IS THAT OF CULTURAL EVOLUTION AND TRANSMISSION: how a group's accumulated solutions to invariant challenges develop and persevere over time. But at the moment, the notion of applying evolutionary theory to culture remains little more than a suggestive trope. Whereas the modern synthesis of evolutionary theory has provided an encompassing scientific framework for the selection and transmission of biological adaptations, a convincing theory of cultural evolution has yet to emerge. One of the greatest challenges for theorists is identifying the appropriate time scales and units of analysis in order to reduce the intractably large and complex phenomenon of "culture" into its component "building blocks." In this paper, we present a model for scientifically investigating cultural processes by analyzing the ways people develop conventions in a series of LEGO construction tasks. The data revealed a surprising pattern in the selection of building bricks as well as features of car design across consecutive building sessions. Our findings support a novel methodology for studying the development and transmission of culture through the microcosm of interactive LEGO design and assembly.

We investigate the gauge/gravity duality in the interaction between two spherical membranes in the 11-dimensional pp-wave background. On the supergravity side, we find the solution to the field equations at locations close to a spherical source membrane, and use it to obtain the light-cone Lagrangian of a spherical probe membrane very close to the source, i.e., with their separation much smaller than their radii. On the gauge theory side, using the BMN matrix model, we compute the one-loop effective potential between two membrane fuzzy spheres. Perfect agreement is found between the two sides. Moreover, the one-loop effective potential we obtain on the gauge theory side is valid beyond the small-separation approximation, giving the full interpolation between interactions of membrane-like objects and that of graviton-like objects

Exploring the Relationship of Organizational Culture and Implicit Leadership Theory to Performance Differences in the Nuclear and Fossil Energy Industry

Science.gov (United States)

Cravey, Kristopher J.

Notable performance differences exist between nuclear and fossil power generation plants in areas such as safety, outage duration efficiency, and capacity factor. This study explored the relationship of organizational culture and implicit leadership theory to these performance differences. A mixed methods approach consisting of quantitative instruments, namely the Organizational Culture Assessment Instrument and the GLOBE Leadership Scales, and qualitative interviews were used in this study. Subjects were operations middle managers in a U.S. energy company that serves nuclear or fossil power plants. Results from the quantitative instruments revealed no differences between nuclear and fossil groups in regards to organizational culture types and implicit leadership theories. However, the qualitative results did reveal divergence between the two groups in regards to what is valued in the organization and how that drives behaviors and decision making. These organizational phenomenological differences seem to explain why performance differences exist between nuclear and fossil plants because, ultimately, they affect how the organization functions.

Three-body B+ → ppK+ and B(+) → ppπ(+) decays are studied using a data sample corresponding to an integrated luminosity of 3.0 fb(-1) collected by the LHCb experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV. Evidence of CP violation in the B(+) → ppK(+) decay is found in regions of the phase space, representing the first measurement of this kind for a final state containing baryons. Measurements of the forward-backward asymmetry of the light meson in the pp rest frame yield A(FB)(ppK(+),m(pp)m(pp) <2.85 GeV/c(2)) = -0.409 ± 0.033 (stat) ± 0.006 (syst). In addition, the branching fraction of the decay B(+) → Λ(1520)p is measured to be B(B(+) → Λ(1520)p) = (3.15 ± 0.48 (stat) ± 0.07 (syst) ± 0.26 (BF)) × 10(-7), where BF denotes the uncertainty on secondary branching fractions.

Full Text Available The Theory of Social Control (TSC is grounded in satisfaction and happiness research. The study investigated the reasons behind relatively low levels of civil and personal satisfaction, subjective social well-being and experienced happiness in the post-communist Hungarian social context. The basic social process uncovered in the research is self-situating, which involves a continuous assessment of social control, which occurs on three psychological dimensions: activity, fairness and connectedness, operated via social flow. The culturally salient outcome of self-situating in Hungary is self-victimizing, meaning a subjective loss of control on all three dimensions. Some of the most important emotional-motivational consequences of self-victimizing are inhibition, regression and isolation, which contribute to various socio-cultural phenomenon such as distrust, bystander strategies, pessimism or anomie across a number of social situations. Based on the emerging theory, the concept of subjective social control is introduced and an expanded three-dimensional model of civil satisfaction, comfort and contribution, along with psychological and cultural implications, are discussed.Key words: social control, self-situating, self-victimizing, activity, fairness, connectedness, inhibition, fury, isolation

More comments on superstring interactions in the pp-wave background

International Nuclear Information System (INIS)

Pankiewicz, Ari

2002-01-01

We reconsider light-cone superstring field theory on the maximally supersymmetric pp-wave background. We find that the results for the fermionic Neumann matrices given so far in the literature are incomplete and verify our expressions by relating them to the bosonic Neumann matrices and proving several non-trivial consistency conditions among them, as for example the generalization of a flat space factorization theorem for the bosonic Neumann matrices. We also study the bosonic and fermionic constituents of the prefactor and point out a subtlety in the relation between continuum and oscillator basis expressions. We give a proof that a recent proposal to use a different fermionic zero-mode vertex, leads to inconsistencies not visible in supergravity. (author)

Effective-gluon model description of inclusive meson production in π+- p and pp collisions

International Nuclear Information System (INIS)

Look, G.W.; Fischbach, E.

1977-01-01

The recently introduced effective-gluon (EG) model is applied to inclusive meson production at large transverse momentum (p/sub t)/from π +- p and pp interactions. In the EG model the dependence of the inclusive differential cross section on p/ sub t/ and center-of-momentum energy √s is characterized by a single universal constant B = 18 GeV 2 ; this constant is obtained by fitting to the inclusive data for pp → cX with c = π +- π 0 , K +- p, and p-bar. Since the EG model requires that the inclusive differential cross sections for π +- p → X/should be characterized by the same constant B, the dependence of these cross sections on p/sub t/and √s should follow from the previous analysis of pp → cX without the introduction of any additional parameters. The only new information required is the form of the momentum distribution function for partons in the incident pion. Several models for this function are considered and it it shown that all of the alternatives lead to approximately the same predictions. Comparison of theory and experiment indicates that the EG model description of the recent Fermilab data of Donaldson et al. is good to approximately 15--20 % per data point over a range of more than 10 5 in the magnitude of the inclusive cross section

Proton-proton and proton-{eta} invariant-mass distributions and the total cross-section for the pp{yields}pp{eta} reaction have been determined near the threshold at an excess energy of Q=10 MeV. The experiment has been conducted using the COSY-11 detector setup and the cooler synchrotron COSY. The determined invariant-mass spectra reveal significant enhancements in the region of low proton-proton relative momenta, similarly as observed previously at higher excess energies of Q=15.5 MeV and Q=40 MeV.

Mit einigen Jahren Verzug folgten die Urogynäkologen den Chirurgen und begannen, Polypropylen-Netze zur Behebung von Beckenbodenvorfällen einzusetzen. PP910-Netze (Vypro II®, Ethicon und PP25-Netze (Ultrapro®, Ethicon werden seit Langem mit gutem Erfolg bei Hernien-Operationen eingesetzt. Das Ziel dieser Studie war herauszufinden, inwieweit sich diese beiden Netze auch für den Einsatz beim Beckenbodenprolaps eignen. Hierzu wurden Fragebögen an Patientinnen versandt, denen in den Jahren 2003 und 2004 diese Netze im Beckenboden implantiert wurden. Die Hauptfragestellungen waren hierbei, inwiefern sich die Symptome des Vorfalles nach der Behandlung verändert hatten und welche Komplikationen nach der Operation aufgetreten waren. Beide Gruppen zeigten nach dem Netzeinsatz deutliche Verbesserungen der Symptomatik bei einer geringen Komplikationsquote. Beim Einsatz von PP910 zeigten sich in 6 % der Fälle Komplikationen, die auf die Implantation des Netzes zurückgeführt werden konnten. Beim Einsatz von PP25 zeigten sogar nur 1,5 % der operierten Frauen netzbedingte Komplikationen. Somit hat sich gezeigt, dass beide Netze gut für die Verwendung im Beckenboden geeignet sind. Vergleicht man die beiden Netze mit anderen Produkten, die derzeit als Implantate im Beckenboden genutzt werden, so zeigt sich ein sehr positives Ergebnis mit signifikant weniger postoperativen Komplikationen unter der Verwendung von PP25-Netzen. Im Rahmen dieser Analyse konnte festgestellt werden, dass PP25 ein sehr sicheres Netz mit ausgesprochen guten Ergebnissen für die Therapie des Beckenbodenprolaps ist.

A theory of modern cultural shifts and meltdowns.

Hochberg, Michael E

2004-08-07

Many cultural attributes such as adornment, language slang, mannerisms and rituals are thought to have little or no influence on individual survival and reproduction, functioning rather as markers of cultural identity that promote group cohesion. Here, I show that if cultural markers are under weak selection and subject to loss or substitution, then the breakdown of cultural cohesiveness may proceed without stabilizing reactions until many or most of a culture's identifiers are forever lost. This may culminate in a 'cultural meltdown', whereby the culture is caught in a vortex of ever-decreasing membership and insufficient selection against the accumulation of unfamiliar markers. In progressively altering the topology of communication from diffusion to broadcasting, globalization may be both accelerating the erosion of cultural identities and amplifying dominance behaviours above their normal adaptive levels.

Pectobacterium carotovorum subsp. carotovorum (formerly Erwinia carotovora subsp. carotovora) is a plant pathogen that causes soft rot and stem rot diseases in several crops, including Chinese cabbage, potato, and tomato. To control this bacterium, we isolated a bacteriophage, PP1, with lytic activity against P. carotovorum subsp. carotovorum. Transmission electron microscopy revealed that the PP1 phage belongs to the Podoviridae family of the order Caudovirales, which exhibit icosahedral heads and short non-contractile tails. PP1 phage showed high specificity for P. carotovorum subsp. carotovorum, and several bacteria belonging to different species and phyla were resistant to PP1. This phage showed rapid and strong lytic activity against its host bacteria in liquid medium and was stable over a broad range of pH values. Disease caused by P. carotovorum subsp. carotovorum was significantly reduced by PP1 treatment. Overall, PP1 bacteriophage effectively controls P. carotovorum subsp. carotovorum.

Datasets of maternal serum PP13 in Caucasian (n = 1078 and Hispanic (n = 242 women were analyzed according to blood groups. In vivo, in vitro and in silico PP13-binding to ABO blood-group antigens and erythrocytes were studied by PP13-immunostainings of placental tissue-microarrays, flow-cytometry of erythrocyte-bound PP13, and model-building of PP13--blood-group H antigen complex, respectively. Women with blood group AB had the lowest serum PP13 in the first trimester, while those with blood group B had the highest PP13 throughout pregnancy. In accordance, PP13-binding was the strongest to blood-group AB erythrocytes and weakest to blood-group B erythrocytes. PP13-staining of maternal and fetal erythrocytes was revealed, and a plausible molecular model of PP13 complexed with blood-group H antigen was built. Adjustment of PP13 MoMs to maternal ABO blood group improved the prediction accuracy of first trimester maternal serum PP13 MoMs for preeclampsia and IUGR.ABO blood group can alter PP13-bioavailability in blood, and it may also be a key determinant for other lectins' bioavailability in the circulation.

Spurred by the recent complete determination of the weak currents in two-nucleon systems up to Ο(Q 3 ) in heavy-baryon chiral perturbation theory, we carry out a parameter-free calculation of the threshold S-factors for the solar pp (proton-fusion) and hep processes in an effective field theory that combines the merits of the standard nuclear physics method and systematic chiral expansion. The power of the EFT adopted here is that one can correlate in a unified formalism the weak-current matrix elements of two-, three- and four-nucleon systems. Using the tritium β-decay rate as an input to fix the only unknown parameter in the theory, we can evaluate the threshold S factors with drastically improved precision; the results are S pp (0) = 3.94 x (1 ± 0.004) x 10 -25 MeV-b and S hep (0) = (8.6 ± 1.3) x 10 -20 keV-b. The dependence of the calculated S-factors on the momentum cutoff parameter Λ has been examined for a physically reasonable range of Λ. This dependence is found to be extremely small for the pp process, and to be within acceptable levels for the hep process, substantiating the consistency of our calculational scheme

Measuring nucleon-nucleon short range correlations (SRCs) has been a goal of the nuclear physics community for many years. They are an important part of the nuclear wave function, accounting for almost all of the high-momentum strength. They are closely related to the EMC effect. While their overall probability has been measured, measuring their momentum distributions is more difficult. In order to determine the best configuration for studying SRC momentum distributions, we measured the 3He(e,e'pp)n reaction, looking at events with high-momentum protons (pp>0.35 GeV/c) and a low-momentum neutron (pn<0.2 GeV/c). We examined two angular configurations: either both protons emitted forward or one proton emitted forward and one backward (with respect to the momentum transfer, q⃗). The measured relative momentum distribution of the events with one forward and one backward proton was much closer to the calculated initial-state pp relative momentum distribution, indicating that this is the preferred configuration for measuring SRC.

Assessing the Implicit Theory of Willpower for Strenuous Mental Activities Scale: Multigroup, across-gender, and cross-cultural measurement invariance and convergent and divergent validity.

Science.gov (United States)

Napolitano, Christopher M; Job, Veronika

2018-05-21

Why do some people struggle with self-control (colloquially called willpower) whereas others are able to sustain it during challenging circumstances? Recent research showed that a person's implicit theories of willpower-whether they think self-control capacity is a limited or nonlimited resource-predict sustained self-control on laboratory tasks and on goal-related outcomes in everyday life. The present research tests the Implicit Theory of Willpower for Strenuous Mental Activities Scale (or ITW-M) Scale for measurement invariance across samples and gender within each culture, and two cultural contexts (the U.S. and Switzerland/Germany). Across a series of multigroup confirmatory factor analyses, we found support for the measurement invariance of the ITW-M scale across samples within and across two cultures, as well as across men and women. Further, the analyses showed expected patterns of convergent (with life-satisfaction and trait-self-control) and discriminant validity (with implicit theory of intelligence). These results provide guidelines for future research and clinical practice using the ITW-M scale for the investigation of latent group differences, for example, between gender or cultures.

The development of efficacious theory-based, culturally relevant interventions to promote cervical cancer prevention among underserved populations is crucial to the elimination of cancer disparities. The purpose of this article is to describe the development of a theory-based, culturally relevant intervention focusing on primary (sexual risk reduction) and secondary (Pap smear) prevention of cervical cancer among Latina immigrants using intervention mapping (IM). The PEN-3 and Health Belief Model provided theoretical guidance for the intervention development and implementation. IM provides a logical five-step framework in intervention development: delineating proximal program objectives, selecting theory-based intervention methods and strategies, developing a program plan, planning for adoption in implementation, and creating evaluation plans and instruments. We first conducted an extensive literature review and qualitatively examined the sociocultural factors associated with primary and secondary prevention of cervical cancer. We then proceeded to quantitatively validate the qualitative findings, which led to development matrices linking the theoretical constructs with intervention objectives and strategies as well as evaluation. IM was a helpful tool in the development of a theory-based, culturally relevant intervention addressing primary and secondary prevention among Latina immigrants.

Dynamic assembly/disassembly of signaling complexes are crucial for cellular functions. Specialized latency and activation chaperones control the biogenesis of protein phosphatase 2A (PP2A) holoenzymes that contain a common scaffold and catalytic subunits and a variable regulatory subunit. Here we show that the butterfly-shaped TIPRL (TOR signaling pathway regulator) makes highly integrative multibranching contacts with the PP2A catalytic subunit, selective for the unmethylated tail and perturbing/inactivating the phosphatase active site. TIPRL also makes unusual wobble contacts with the scaffold subunit, allowing TIPRL, but not the overlapping regulatory subunits, to tolerate disease-associated PP2A mutations, resulting in reduced holoenzyme assembly and enhanced inactivation of mutant PP2A. Strikingly, TIPRL and the latency chaperone, α4, coordinate to disassemble active holoenzymes into latent PP2A, strictly controlled by methylation. Our study reveals a mechanism for methylation-responsive inactivation and holoenzyme disassembly, illustrating the complexity of regulation/signaling, dynamic complex disassembly, and disease mutations in cancer and intellectual disability.

Cultural Learning Redux.

Tomasello, Michael

2016-05-01

M. Tomasello, A. Kruger, and H. Ratner (1993) proposed a theory of cultural learning comprising imitative learning, instructed learning, and collaborative learning. Empirical and theoretical advances in the past 20 years suggest modifications to the theory; for example, children do not just imitate but overimitate in order to identify and affiliate with others in their cultural group, children learn from pedagogy not just episodic facts but the generic structure of their cultural worlds, and children collaboratively co-construct with those in their culture normative rules for doing things. In all, human children do not just culturally learn useful instrumental activities and information, they conform to the normative expectations of the cultural group and even contribute themselves to the creation of such normative expectations. © 2016 The Author.

By using (pp) interactions at three different CM energies, ( \\sqrt{s})/sub pp/=30, 44, 62 GeV, it is shown that the average charged- particle multiplicity (n/sub ch/) vs. the invariant mass of the hadronic system m/sub 1,2/ has the same behaviour as it has vs. 2E/sup had/. Moreover, in both cases (n/sub ch/) is shown to be nearly independent of ( \\sqrt{s})/sub pp/ and in good agreement with the average charged-particle multiplicity measured in the (e^{+}e/sup - /) annihilation.

Cruickshank, Andrew; Collins, Dave; Minten, Sue

2014-02-01

Stimulated by growing interest in the organizational and performance leadership components of Olympic success, sport psychology researchers have identified performance director-led culture change as a process of particular theoretical and applied significance. To build on initial work in this area and develop practically meaningful understanding, a pragmatic research philosophy and grounded theory methodology were engaged to uncover culture change best practice from the perspective of newly appointed performance directors. Delivered in complex and contested settings, results revealed that the optimal change process consisted of an initial evaluation, planning, and impact phase adjoined to the immediate and enduring management of a multidirectional perception- and power-based social system. As the first inquiry of its kind, these findings provide a foundation for the continued theoretical development of culture change in Olympic sport performance teams and a first model on which applied practice can be based.

The Importance of the Cultural-Historical Theory for Education. Some Meditations on Learning, Development, Activity, and Creativity

Full Text Available “What are the main items showing the importance of cultural-historical psychology for education?” It is much easier to put such a question than to give an appropriate answer. Different experts in this area definitely propose different answers to it. In this article I would try to present my answer from my perspective. It seems that our understanding of Vygotsky’s theory is so deep and complete that any question of missed links or hidden messages does not make any sense. What essentially new could be found in this area after more than 40 years of discovering of the cultural-historical theory by generations of researchers? However, I will try to show that there are missed links in our understanding of Vygotsky’s theoretical approach. Even more, I will try to show that there is a hidden message from Vygotsky which remains unclaimed. I will try to show then that both items (the missed link and the hidden message are connected with the idea of development in terms of drama.

Study of PP/Polybutene Blends Modified by Gamma Irradiation and HMS-PP/Polybutene Blends

International Nuclear Information System (INIS)

2006-01-01

The polypropylene (PP) has been applied to a wide range of production due to its various excellent properties such as cheapness, high stiffness, chemical resistance, no environmental pollution when incinerated, low specific density and good mechanical properties. However, PP is a linear polymer which exhibits low melt strength. One of the effective approaches to achieve high melt strength (HMS) is to add chain branches onto backbone polymers. High melt strength polypropylene (HMS-PP) has been recently developed and introduced in the market by the major international polypropylene producers. As a consequence different methods have been applied to modify polypropylenes by chain branches. The technology obtained by IPEN together with EMBRARAD and BRASKEM comprises chain branches added onto backbone species using gamma radiation, which is generated from a Co 6 0 source. Such radiation is very convenient in order to improve polymer materials by grafting, crosslinking and degradation. Another important approach to the development of polymer materials is based on the combination of different polymers into a new product having some of the desired properties of each component. In this work, gamma irradiation technique was used to induce chemical changes in commercial polypropylene (HMS-PP) that was after blended with polybutene and in polypropylene/polybutene blends. The samples were irradiated with a 60 C o source at doses of 12,5 and 20kGy in the presence of acetylene. It was investigated how the two different routes of blends processing can modify their properties. Indeed the results from melt flow, gel fraction and rheology reveal the influence of the process route in the blends properties. Effects on the elongation at break and break strength were observed by the results of mechanical tests. The results from rheology demonstrated an increase in melt strength and drawability of the blends

Culture in the mind's mirror: how anthropology and neuroscience can inform a model of the neural substrate for cultural imitative learning.

Science.gov (United States)

Losin, Elizabeth A Reynolds; Dapretto, Mirella; Iacoboni, Marco

2009-01-01

Cultural neuroscience, the study of how cultural experience shapes the brain, is an emerging subdiscipline in the neurosciences. Yet, a foundational question to the study of culture and the brain remains neglected by neuroscientific inquiry: "How does cultural information get into the brain in the first place?" Fortunately, the tools needed to explore the neural architecture of cultural learning - anthropological theories and cognitive neuroscience methodologies - already exist; they are merely separated by disciplinary boundaries. Here we review anthropological theories of cultural learning derived from fieldwork and modeling; since cultural learning theory suggests that sophisticated imitation abilities are at the core of human cultural learning, we focus our review on cultural imitative learning. Accordingly we proceed to discuss the neural underpinnings of imitation and other mechanisms important for cultural learning: learning biases, mental state attribution, and reinforcement learning. Using cultural neuroscience theory and cognitive neuroscience research as our guides, we then propose a preliminary model of the neural architecture of cultural learning. Finally, we discuss future studies needed to test this model and fully explore and explain the neural underpinnings of cultural imitative learning.

Characteristics of the groups of charged particles in bar pp,pp and K-p interactions at 32 GeV/c

In the clan model, a method is developed for determining the following characteristics of the groups of charged particles: group multiplicity in an interval, particle multiplicity in a group, and width distribution of groups. Distribution densities are obtained for particles originating from clans produced at a given rapidity point with given width in bar pp, K - p, and pp interactions at 32 GeV/c. It is shown that the differences in the rate of growth of factorial moments in bar pp and K - p interactions are due to a difference in the relative contributions of small-width clans. 12 refs., 13 figs., 2 tabs

2009-01-01

The radiation process has played an important role to produce polymers with controlled rheological properties. The main scope of the study is to evaluate the stability of High melt strength polypropylene (HMS-PP) prepared by gamma irradiation of PP (spheres) under acetylene atmosphere followed by a heating step to terminate reactions, in different doses of 12.5 kGy and 20 kGy. The samples submitted to the natural ageing for a period of one year were characterized by: thermogravimetry (TG), differential scanning calorimetry (DSC), infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The fundamental process that is believed to be the most significant in the mechanism of photooxidative degradation is the formation of hydroperoxides. The high energy UV light is capable of initiating bond scission within the polymer backbone, which leads to further chemical modification of the bonds via scissions and chain reactions through formation of radical species. The results showed that in pristine and HMS-PP samples exposed to UV radiation, oxidation reactions occur, resulting in chain scissions. The reactions occur preferentially in the amorphous phase owing to the higher permeability of oxygen. (author)

A detailed investigation of proton-antiproton interactions at low energy has become feasible with the commissioning of the LEAR facility in 1983. We shall shortly review the status of bar pp annihilation at rest and the physics motivations for second generation experiments with the Crystal Barrel detector. This type of detector would be adequate for the study of both Kp and bar pp interactions on an extracted beam of the KAON Factory. We shall conclude with a few remarks on the physics opportunities with bar p's at the KAON Factory which, in our opinion, will not be covered by the present LEAR facility. 11 refs., 10 figs., 2 tabs

Characterisation and expression of a PP1 serine/threonine protein phosphatase (PfPP1 from the malaria parasite, Plasmodium falciparum: demonstration of its essential role using RNA interference

Directory of Open Access Journals (Sweden)

Musiyenko Alla

2002-04-01

Full Text Available Abstract Background Reversible protein phosphorylation is relatively unexplored in the intracellular protozoa of the Apicomplexa family that includes the genus Plasmodium, to which belong the causative agents of malaria. Members of the PP1 family represent the most highly conserved protein phosphatase sequences in phylogeny and play essential regulatory roles in various cellular pathways. Previous evidence suggested a PP1-like activity in Plasmodium falciparum, not yet identified at the molecular level. Results We have identified a PP1 catalytic subunit from P. falciparum and named it PfPP1. The predicted primary structure of the 304-amino acid long protein was highly similar to PP1 sequences of other species, and showed conservation of all the signature motifs. The purified recombinant protein exhibited potent phosphatase activity in vitro. Its sensitivity to specific phosphatase inhibitors was characteristic of the PP1 class. The authenticity of the PfPP1 cDNA was further confirmed by mutational analysis of strategic amino acid residues important in catalysis. The protein was expressed in all erythrocytic stages of the parasite. Abrogation of PP1 expression by synthetic short interfering RNA (siRNA led to inhibition of parasite DNA synthesis. Conclusions The high sequence similarity of PfPP1 with other PP1 members suggests conservation of function. Phenotypic gene knockdown studies using siRNA confirmed its essential role in the parasite. Detailed studies of PfPP1 and its regulation may unravel the role of reversible protein phosphorylation in the signalling pathways of the parasite, including glucose metabolism and parasitic cell division. The use of siRNA could be an important tool in the functional analysis of Apicomplexan genes.

Assimilating to Hierarchical Culture: A Grounded Theory Study on Communication among Clinical Nurses

Science.gov (United States)

2016-01-01

The purpose of this study was to generate a substantive model that accounts for the explanatory social processes of communication in which nurses were engaged in clinical settings in Korea. Grounded theory methodology was used in this study. A total of 15 clinical nurses participated in the in-depth interviews. “Assimilating to the hierarchical culture” emerged as the basic social process of communication in which the participants engaged in their work environments. To adapt to the cultures of their assigned wards, the nurses learned to be silent and engaged in their assimilation into the established hierarchy. The process of assimilation consisted of three phases based on the major goals that nurses worked to achieve: getting to know about unspoken rules, persevering within the culture, and acting as senior nurse. Seven strategies and actions utilized to achieve the major tasks emerged as subcategories, including receiving strong disapproval, learning by observing, going silent, finding out what is acceptable, minimizing distress, taking advantages as senior nurse, and taking responsibilities as senior nurse. The findings identified how the pattern of communication in nursing organizations affected the way in which nurses were assimilated into organizational culture, from individual nurses’ perspectives. In order to improve the rigid working atmosphere and culture in nursing organizations and increase members’ satisfaction with work and quality of life, managers and staff nurses need training that focuses on effective communication and encouraging peer opinion-sharing within horizontal relationships. Moreover, organization-level support should be provided to create an environment that encourages free expression. PMID:27253389

Towards a Theory of Urban Fragmentation: A Cross-Cultural Analysis of Fear, Privatization, and the State

Setha Low

2006-10-01

Full Text Available This paper employs a cross-cultural analysis to explore regional and national variations in residential gating and enclosure as a first step in developing an integrated theory of urban fragmentation. Utilizing data from the urban and suburban United States, Latin America and China, a series of dimensions are compared: 1 domestic architecture, 2 urban/suburban settlement pattern, 3 the role of the state, 4 governance, 5 citizenship, 6 cultural meaning, 7 identity, 8 provision of goods and services, 9 taxation, 10 degree of privatization, 11 cultural pattern of social sanction, and 12 fear of crime and others. This comparative analysis locates culturally meaningful and theoretically significant distinctions among the regions and provides data for the development of explanatory models in which each region varies along a dimensional continuum.  At the macro-level of analysis, the impact of globalization and flexible accumulation with increased local heterogeneity, increases in inequality and changes in perceived crime rate emerge as the major underlying factors in the fear of crime and others found in all three regions.  At a micro-level, differences in cultural meanings are explained by local social and political contexts, while provision of goods and services and governance depend on club realm economic explanations.

Surface treatments on a polypropylene (PP) fibre have contributed to the improvement of fibre/concrete adhesion in fibre-reinforced concrete. The treatments to the PP fibre were characterized by contact angle measurements, ATR-IR and XPS to analyse chemical alterations. The surface topography and fibre/concrete interaction were analysed by several microscopic techniques, namely optical petrographic, and scanning electron microscopy. Treatment modified the surface chemistry and topography of the fibre by introducing sodium moieties and created additional fibre surface roughness. Modifications in the fibre surface led to an increase in the adhesion properties between the treated fibres and concrete and an improvement in the mechanical properties of the fibre-reinforced concrete composite as compared to the concrete containing untreated PP fibres. Compatibility with the concrete and increased roughness and mineral surface was also improved by nucleated portlandite and ettringite mineral association anchored on the alkaline PP fibre surface, which is induced during treatment.

2009-01-01

The phosphorylated protein pp65 of human Cytomegalovirus (HCMV) is the predominant virion protein and the major tegument constituent. It plays important roles in HCMV infection and virion assembly. Live cell imaging and fluorescence recovery after photobleaching (FRAP) analysis showed that HCMV pp65 accumulated dynamically in punctuate nuclear foci when transiently expressed in mammalian cells. Fluorescence resonance energy transfer (FRET) imaging disclosed that pp65 can self-interact in its localization foci. Yeast two-hybrid assay verified that pp65 is a self-associating protein, and the N-terminal amino acids 14-22 were determined to be essential for pp65 self-association. However, these amino acids were not related to pp65 localization in the specific nuclear foci. The interaction of pp65 and ppUL97 was also studied by FRET microscopy, and the result suggested that there is another signal sequence in pp65, being the ppUL97 phosphorylation site, that is responsible for localization of pp65 in nuclear foci. These results help to understand the function of pp65 in HCMV infection and virion morphogenesis.

Personality disorders and culture: contemporary clinical views (Part B).

Alarcón, R D; Foulks, E F

1995-01-01

This article reviews the basic concepts surrounding the clinical relationships between culture and personality disorders (PDs). Part A of this article, which appeared in Cultural Diversity and Mental Health, Vol. 1, No. 1, pp 3-17 (1995), examined the interpretive/explanatory and pathogenic/ pathoplastic roles of culture. Herein, culture's role as a diagnostic/nosological factor is discussed through the use of measurement instruments and the cultural formulation included in DSM-IV (American Psychiatric Association, 1994). In addition to these three roles, some authors would also consider a therapeutic/protective function for cultured in PDs. Following a critique of the biological perspective, a research model based on the definition of the cultural profile and the estimation of the cultural distance between clinical examiners and populations is proposed. It is important to reject both biological reductionism and the extremes of cultural determinism, in order to better assess the intraethnic distribution of psychopathology, and interethnic variations represented by the notion of cultural relativism.

J/psi production in pp collisions from ALICE

CERN Multimedia

CERN. Geneva

2012-01-01

The ALICE experiment studied J/psi production in the mu+mu- and e+e- decay channels. Inclusive cross sections were measured at both forward and central rapidity down to zero transverse momentum. The results are compared with NRQCD calculations and, for the pp sample collected at sqrt(s)=2.76 TeV, are used as a reference for the determination of nuclear effects on J/psi production in Pb-Pb. At central rapidity, the fraction of J/psi coming from B-decays has been evaluated down to p_T=1.3 GeV/c. In addition, the J/psi yield has been found to linearly increase as a function of the charged hadron multiplicity produced in the collision. Finally, the first LHC results on J/psi polarization, an essential observable for the understanding of the production mechanisms and for theory comparisons, will be presented.

Evaluation of the effect of the incorporation of rubber tire waste particles on the properties of PP, HIPS and PP/HIPS matrices

2013-01-01

Full Text Available In recent years, the consumption of plastics has been increasing and as consequence, the waste generated has also increased. Rubber tire (RT waste is another residue which causes significant problems to society. In view of the considerable amounts of RT waste generated, this study aimed to evaluate the influence of the incorporation of RT particles into post-consumer thermoplastic matrices such as polypropylene (PP, high impact polystyrene (HIPS and PP/HIPS blends and the modification of the physical, morphological, rheological and mechanical properties. The particle sizes of the RT used were <500 and 500-1000 μm. The RT content was 10% w/w and the weight ratio for the PP/HIPS blend was 4/1, with processing by injection molding. The results showed that the smaller (500 μm particle size led to a decrease in the melt flow rate (MFR of the PP/RT composites (increased viscosity and an increase for the HIPS/RT composites. On the other hand, the larger particles (1000 μm led to a decrease in the mechanical performance of the PP/RT and HIPS/RT blends when compared with the neat polymers (PP and HIPS post-consumer. The observed decrease in the mechanical properties of these composites was due to weak filler/matrix interactions, which can be visualized in images by scanning electron microscopy (SEM of the fracture surface after tensile testing.

Miller, J

1997-01-01

The domain of inquiry for this study was the influence of the American political environmental context on professional and generic care patterns, expressions, and meanings of Czech American immigrants. The purpose of the research was to document, describe, interpret, and analyze the diversities and universalities of professional and generic care for this cultural group, to provide culturally congruent care to Czech Americans, and to explicate the role of politics as an influence on care patterns, health, and well being. The researcher's former transcultural ethnonursing study in Prague, Czechoslovakia in 1991 served as a stimulus for this in-depth study on politics and care. Twelve key and twenty general informants were interviewed. Five major themes were identified. The researcher discovered that the capitalist economic market structure of the United States influenced informant lifeways in all dimensions of Leininger's Theory of Culture Care Diversity and Universality, as depicted in the Sunrise Model. Specific care patterns discovered included care as choice, care as responsibility, and care as helping each other. Findings related to professional and generic care supported researcher predictions that generic culture care patterns would be important to immigrants. Provisions for culturally congruent nursing care were articulated based on research findings.

D. Oyserman, H. M. Coon, and M. Kemmelmeier (2002) provide a most comprehensive review of empirical studies that used attitudinal surveys to capture cultural variations in individualism and collectivism. In the present article, the author suggests that the cross-cultural validity of attitudinal surveys can no longer be taken for granted. Moreover, the meta-theory underlying this literature (called the entity view of culture) is called into question. The author presents an alternative meta-theory (called the system view of culture) and discusses its implications for future work in cultural and cross-cultural psychology.

Intermittency patterns in pp collisions at 360 GeV/c

International Nuclear Information System (INIS)

Singh, J.B.; Kohli, J.M.

1991-01-01

The intermittency effect has been observed in pp collisions at 360 GeV/c and the strength decreases with the increase in multiplicity. The low multiplicity events in pp data (n ch ≤ 8), anti pp collisions (n ch ≤ 15) at Collider energy and elementary interaction (e + e - , μp) samples have almost the same strength. Most likely, few sources seem to contribute at lower multiplications. The intermittency effect is less in pp data compared to e + e - data, however it is fairly strong as compared to nucleus data. The presently used hadronization models DPM, LUND and FRITIOF do not reproduce the results fully. (orig.)

Theory of mind is claimed to develop universally among humans across cultures with vastly different folk psychologies. However, in the attempt to test and confirm a claim of universality, individual studies have been limited by small sample sizes, sample specificities, and an overwhelming focus on Anglo-European children.

Full Text Available Students from around the world are increasingly interested in learning new languages and be inserted in different cultures, increasing the numbers of international mobility. However, when traveling to another country, cultural differences are strongly perceived, even if in different ways, influencing the adaptation process. Given the importance and growth of the international academic mobility, this study analyzes the process of cultural adaptation of students in mobility, considering the assumptions of the theory of curves "U" and "W". As for the methodology, it is a descriptive research with quantitative approach. Data collection was conducted through closed questionnaires sent to international students from different countries who have studied or are still studying in a Brazilian Institution of Higher Education. The results showed that after the stage of culture shock, students feel more connected to local culture, make more friends and feel more confident. It was confirmed also that almost all international students managed to adapt well to local customs.

Symmetry of Uniaxial Global Landau--de Gennes Minimizers in the Theory of Nematic Liquid Crystals

KAUST Repository

Henao, Duvan; Majumdar, Apala

2012-01-01

We extend the recent radial symmetry results by Pisante [J. Funct. Anal., 260 (2011), pp. 892-905] and Millot and Pisante [J. Eur. Math. Soc. (JEMS), 12 (2010), pp. 1069- 1096] (who show that the equivariant solutions are the only entire solutions of the three-dimensional Ginzburg-Landau equations in superconductivity theory) to the Landau-de Gennes framework in the theory of nematic liquid crystals. In the low temperature limit, we obtain a characterization of global Landau-de Gennes minimizers, in the restricted class of uniaxial tensors, in terms of the well-known radial-hedgehog solution. We use this characterization to prove that global Landau-de Gennes minimizers cannot be purely uniaxial for sufficiently low temperatures. Copyright © by SIAM.

Somatic embryogenesis in cell cultures of Glycine species.

Gamborg, O L; Davis, B P; Stahlhut, R W

1983-08-01

This report describes the development of procedures for the production of somatic embryos in cell cultures of Glycine species including soybean. The conditions for callus induction and initiation of rapidly growing cell suspension cultures were defined. Methods for inducing embryogenesis were tested on 16 lines of several Glycine species and cultivars of soybean. The SB-26 Culture of a G. soja gave the best results and was used in the experiments. Embryogenesis required the presence of picloram or 2,4-D. AMO 1618, CCC, PP-333 and Ancymidol enhanced the embryogenesis frequency. Plants of the G. soja (SB-26) were grown to maturity from seed-derived shoot tips. Characteristics of the plants are discussed.

Critical Race Theory and the Limits of Relational Theory in Social Work with Women.

Science.gov (United States)

Quinn, Camille R; Grumbach, Giesela

2015-01-01

The authors present a conceptual framework for expanding the use of relational theory with African-American women. Relational theory (RT) informs practice with women but is inadequate in addressing all aspects of culture and identity. RT presumes that all women desire or are able to make therapeutic connections, yet race, gender, and cultural experiences influence their ability to do so. Successful practice with minority women must address racism and its impact. Critical race theory (CRT) that incorporates a solution-focused (SF) approach is well-suited to address the limits of RT. This overview of a CRT/SF approach describes treatment for diverse women that extends RT and enhances effective social work practice to provide culturally sensitive treatment to women.

2008-10-01

A combined analysis of the published data on the pp → dK +¯0 reaction at excess energies of 47.4MeV and 104.7MeV is presented that takes into account final-state interactions in both the K +¯0 and ¯0 d channels. The strong attraction of the antikaons with nucleons, already noted for the pp → ppK + K - reaction, leads here to very different ¯0 d and K+d distributions, with the former being dominantly in an s -wave and the latter in a p -wave. Evidence is also found from the K +¯0 distributions for the production of the a 0 +(980) scalar resonance. The inclusion of both final-state interactions improves the description of the energy dependence of the pp → dK +¯0 total cross-section.

Pressure, flow and hydraulic interference measurements in ONKALO at Olkiluoto, drillholes ONK-PP262 and ONK-PP274

Hurmerinta, E.; Pekkanen, J.; Komulainen, J.; Rouhiainen, P.

2012-01-01

The general purpose of these studies is to characterize the fracture network and groundwater flow properties in a volume of rock, which is representative of the rock close to deposition holes. As a part of the studies hydraulic tests and flow measurements were applied in two drillholes in hydraulically poorly conductive bedrock. This report presents the principles of the methods as well as the results of the measurements carried out in the underground facilities of ONKALO. The measurements were conducted in drillholes ONK-PP262 and ONK-PP274 between May 9, 2010 and June 9, 2011. The aim of the measurements was to obtain pressure in the closed drillholes, to detect water yielding fractures by flow measurements, to obtain transmissivity with overpressure and drawdown tests and to study hydraulic interference between the drillholes by cross-hole hydraulic tests. The PFL DIFF probe was used to detect flow within single fractures in the drillhole. Transmissive water yielding fractures were found at depths 17.9 m, 16.9 m and 16.4 m in ONK-PP262 and at depths 19.8 m and 19.5 m in ONK-PP274. The cross-hole hydraulic tests included three basic phases. Flow was measured in one drillhole when the other drillhole was open, closed or overpressurized. The cross-hole hydraulic tests were carried out to both directions in the two drillholes. (orig.)

Gibbs-Strauss, Summer L.; Davis, Scott C.; O'Hara, Julia A.; Hoopes, P. Jack; Hasan, Tayyaba; Pogue, Brian W.

2008-02-01

Aminolevulinic Acid (ALA) is a prodrug which can be administered to cells, animals or patients after which it is transformed via the Heme synthesis pathway into the fluorescent molecule Protoporphyrin IX (PpIX). PpIX has been shown to be useful as both a photosensitizer for photodynamic therapy (PDT) and as a fluorescence imaging contrast agent. The ALA-PpIX system not only provides contrast for fluorescence imaging but also gives information about the metabolic activity of the imaged tissue and thus could be useful for monitoring cancer therapy. In the current study skin photobleaching was examined to determine if PpIX fluorescence contrast in malignant brain tumors could be better visualized noninvasively. Red light photobleaching decreased skin PpIX fluorescence and increased the ability to noninvasively quantify PpIX fluorescence in murine gliomas, as in vivo measurements of mean PpIX fluorescence more closely matched ex vivo quantification following skin photobleaching. Three doses of blue light photobleaching (4 J/cm2, 8 J/cm2 and 12 J/cm2) were tested and determined to give similar levels of skin photobleaching as well as a similar window of decreased skin PpIX fluorescence for noninvasive fluorescence imaging following the photobleaching dose administration.

2009-04-01

Suomen Malmi Oy (Smoy) core drilled four 24.88 - 25.39 m long investigation drillholes at Olkiluoto in June 2008. The identification numbers of the holes are OL-PP66, OL-PP67, OL-PP68 and OL-PP69. The drillholes are 75.7 mm by diameter. Drillholes were core drilled with the diamond drill rig Diamec 1000. The drilling water was taken from the ONKALO drilling water pipeline and premixed sodium fluorescein was used as a label agent in the drilling water. The labelled drilling water was driven to the drilling places in a tank. In addition to drilling the drill cores were logged and reported by geologist. During geological investigation the following parameters were logged: lithology, foliation, fracture parameters, fractured zones, core loss, weathering, fracture frequency, RQD and rock quality. The main rock types in the drillholes are diatexitic and veined gneisses and pegmatitic granite. The average fracture frequency in holes varied from 3.9 pcs/m to 5.8 pcs/m. The average RQD values varied from 84 % to 93 %. In the drillhole OL-PP66 two fractured zones were penetrated and in OL-PP69 one fractured zone. The drill cores OL-PP67 and OL-PP68 showed no fractured zones. Smoy also carried out optical imaging of the drillholes. The assignment included the field work and the data processing. This report describes the field operation, the equipment as well as the processing procedures and shows the obtained results and their quality. The raw and processed data are delivered digitally in WellCAD and PDF format. (orig.)

Damage of guinea pig heart and arteries by a trioleate-enriched diet and of cultured cardiomyocytes by oleic acid.

Directory of Open Access Journals (Sweden)

Josef Krieglstein

2010-03-01

Full Text Available Mono-unsaturated fatty acids (MUFAs like oleic acid have been shown to cause apoptosis of cultured endothelial cells by activating protein phosphatase type 2C alpha and beta (PP2C. The question arises whether damage of endothelial or other cells could be observed in intact animals fed with a trioleate-enriched diet.Dunkin-Hartley guinea pigs were fed with a trioleate-enriched diet for 5 months. Advanced atherosclerotic changes of the aorta and the coronary arteries could not be seen but the arteries appeared in a pre-atherosclerotic stage of vascular remodelling. However, the weight and size of the hearts were lower than in controls and the number of apoptotic myocytes increased in the hearts of trioleate-fed animals. To confirm the idea that oleic acid may have caused this apoptosis by activation of PP2C, cultured cardiomyocytes from guinea pigs and mice were treated with various lipids. It was demonstrable that oleic acid dose-dependently caused apoptosis of cardiomyocytes from both species, yet, similar to previous experiments with cultured neurons and endothelial cells, stearic acid, elaidic acid and oleic acid methylester did not. The apoptotic effect caused by oleic acid was diminished when PP2C alpha and beta were downregulated by siRNA showing that PP2C was causally involved in apoptosis caused by oleic acid.The glycerol trioleate diet given to guinea pigs for 5 months did not cause marked atherosclerosis but clearly damaged the hearts by activating PP2C alpha and beta. The diet used with 24% (wt/wt glycerol trioleate is not comparable to human diets. The detrimental role of MUFAs for guinea pig heart tissue in vivo is shown for the first time. Whether it is true for humans remains to be shown.

EXPLORATORY STUDY OF OBSTACLES IN SAFETY CULTURE DEVELOPMENT IN THE CONSTRUCTION INDUSTRY: A GROUNDED THEORY APPROACH

Directory of Open Access Journals (Sweden)

Bonaventure H.W. Hadikusumo

2010-06-01

Full Text Available The aim of this paper is to analyse the obstacles that prevent the development of a safety culture in Thailand’s large construction industry from various managerial points of view. Qualitative research methods were used by performing a series of semi-structured interviews of eight case studies selected from six prominent construction firms to investigate the obstacles they face. Glaser’s keyword coding from Grounded Theory was used to reduce the information load after the interviews. Our findings revealed that the factors influencing the successful development of a safety culture in the construction industry are the workers, the characteristics of construction, the subcontractors, the supervisors, and external factors. Based on the frequency analysis, the main obstacles in developing a safety culture result from problems related to the workers themselves. The three most frequently discussed problems are unskilled workers, unsafe worker habits, and high worker turnover. Our results also suggest that managers should encourage engagement from their workers to optimise the successful implementation of safety programs and their long-term improvement.

The Conditions under which Growth-Fostering Relationships Promote Resilience and Alleviate Psychological Distress among Sexual Minorities: Applications of Relational Cultural Theory

Science.gov (United States)

Mereish, Ethan H.; Poteat, V. Paul

2015-01-01

Relational cultural theory posits that resilience and psychological growth are rooted in relational connections and are facilitated through growth-fostering relationships. Framed within this theory, the current study examined the associations between growth-fostering relationships (i.e., relationships characterized by authenticity and mutuality) with a close friend and psychological distress among sexual minorities. More specifically, we tested the moderating effects of individuals’ internalized homophobia and their friend’s sexual orientation on the associations between growth-fostering relationship with their close friend and level of psychological distress. A sample of sexual minorities (N = 661) were recruited online and completed a questionnaire. The 3-way interaction between (a) growth-fostering relationship with a close friend, (b) the close friend’s sexual orientation, and (c) internalized homophobia was significant in predicting psychological distress. Among participants with low levels of internalized homophobia, a stronger growth-fostering relationship with a close heterosexual or LGBT friend was associated with less psychological distress. Among participants with high levels of internalized homophobia, a stronger growth-fostering relationship with a close LGBT friend was associated with less psychological distress but not with a heterosexual friend. Our results demonstrate that growth-fostering relationships may be associated with less psychological distress but under specific conditions. These findings illuminate a potential mechanism for sexual minorities’ resilience and provide support for relational cultural theory. Understanding resilience factors among sexual minorities is critical for culturally sensitive and affirmative clinical practice and future research. PMID:26380836

With the development of globalization and the intimate touch between China and western countries, it is the information exchange between countries that makes the rapid development of English culture and the inheritance of Chinese culture. And as the important tools and two modern cultural medias for cultural exchange, TV and film are essential in our life, and subtitle translation appeared in people's sights. As one of the most important theories in translation, U. S. Bureau was who first use the cultural adaptation theory. He defined it as' a psychological change from an alien culture to a new cultural.'(1883)It was the basic theory in translation so it must abide by every translator. In this thesis, we will take Western magical fantasy series of movies-Harry Potter as an example, analyzing the importance of the cultural adaptability. Firstly, I will briefly introduce the book and movie about Harry Potter, then explain the content and application of this function, finaly this paper will combine cultural difference and custom difference with religion difference to illustrate that cultural adaptability is main theory in translation. Combining with Harry Potter, I hope this research will help people to have a better understanding of cross-cultural communication and make this film more colorful and shining.

2015-07-01

The ''ppK{sup -}'' is a well established state in theory and is a candidate for a new kind of hadronic matter formed by antikaons and nucleons. The HADES spectrometer at GSI has probed the existence of such a state by measuring its possible decay products p and Λ. These decay products have been studied specifically in the reaction p+p → p+K{sup +}+Λ at a beam kinetic energy of 3.5 GeV. A partial wave analysis, performed on this final state, helped in describing the event distributions, which is a necessary condition to search for an additional small signal in the statistic. We have found no indication for the production of a kaonic nuclear bound state in our data and have, thus, set an upper limit for its production cross section. Furthermore, did we repeat the analysis of the DISTO collaboration in which a signal like distribution appeared in so-called deviation spectra. We can show that this method is error-prone in terms of the applied selection cuts and is, thus, not reliable in order to make statements about the ''ppK{sup -}''.

Beyond the 'new cross-cultural psychiatry': cultural biology, discursive psychology and the ironies of globalization.

Science.gov (United States)

Kirmayer, Laurence J

2006-03-01

The 'new cross-cultural psychiatry' heralded by Kleinman in 1977 promised a revitalized tradition that gave due respect to cultural difference and did not export psychiatric theories that were themselves culture bound. In the ensuing years, the view of culture within anthropology has continued to change, along with our understanding of the relationship of biological processes to cultural diversity, and the global political economic contexts in which mental health care is delivered. This article considers the implications of these new notions of culture, biology and the context of practice for theory in cultural psychiatry. The future of cultural psychiatry lies in advancing a broad perspective that: (a) is inherently multidisciplinary (involving psychiatric epidemiology, medical anthropology and sociology, cognitive science and social psychology), breaking down the nature/culture dichotomy with an integrative view of culture as a core feature of human biology, while remaining alert to cultural constructions of biological theory; (b) attends to psychological processes but understands these as not exclusively located within the individual but as including discursive processes that are fundamentally social; and (c) critically examines the interaction of both local and global systems of knowledge and power. Globalization has brought with it many ironies for cultural psychiatry: Transnational migrations have resulted in cultural hybridization at the same time as ethnicity has become more salient; the call for evidence-based medicine has been used to limit the impact of cultural research; and cultural psychiatry itself has been co-opted by pharmaceutical companies to inform marketing campaigns to promote conventional treatments for new populations. Cultural psychiatry must address these ironies to develop the self-critical awareness and flexibility needed to deliver humane care in shifting contexts.

Difference flow and electrical conductivity measurements at the Olkiluoto site in Eurajoki, drillholes OL-PP66 - OL-PP69

International Nuclear Information System (INIS)

Poellaenen, J.

2009-04-01

The Posiva Flow Log, Difference Flow Method (PFL DIFF) uses a flowmeter that incorporates a flow guide and can be used for relatively quick determinations of hydraulic conductivity and hydraulic head in fractures/fractured zones in cored drillholes. This report presents the principles of the method and the results of measurements carried out in drillholes OL-PP66, OL-PP67, OL-PP68 and OL-PP69 at the Olkiluoto investigation site in August 2008. All the drillholes discussed in this report are ground holes. The same measuring programme was employed in all four drillholes. The section length of the flow guide was either 2 m or 0.5 m. Flow into the drillhole or from the drillhole to the bedrock was measured within the section lengths and carried out in both pumped and natural (i.e. un-pumped) conditions. Calculations of the transmissivity (T) and the hydraulic head (h) of the zones are shown in the results. The device used includes a sensor for single point resistance (SPR). SPR was measured in connection with flow measurements. The electrical conductivity (EC) of fracture-specific water was measured in chosen fractures in some of the drillholes. Fractures were selected on the basis of the measured flow from fracture to drillhole. The EC of the drillhole water was also measured. (orig.)

In a certain kinematic limit, where the effects of spacetime curvature (and other background fields) greatly simplify, the light-cone gauge world-sheet action for a type IIB superstring on AdS_5 x S^5 reduces to that of a free field theory.

Scalar fields nonminimally coupled to pp waves

International Nuclear Information System (INIS)

Ayon-Beato, Eloy; Hassaiene, Mokhtar

2005-01-01

Here, we report pp waves configurations of three-dimensional gravity for which a scalar field nonminimally coupled to them acts as a source. In absence of self-interaction the solutions are gravitational plane waves with a profile fixed in terms of the scalar wave. In the self-interacting case, only power-law potentials parameterized by the nonminimal coupling constant are allowed by the field equations. In contrast with the free case the self-interacting scalar field does not behave like a wave since it depends only on the wave-front coordinate. We address the same problem when gravitation is governed by topologically massive gravity and the source is a free scalar field. From the pp waves derived in this case, we obtain at the zero topological mass limit, new pp waves solutions of conformal gravity for any arbitrary value of the nonminimal coupling parameter. Finally, we extend these solutions to the self-interacting case of conformal gravity

Most sociological research assumes that social network composition shapes individual beliefs. Network theory and research has not adequately considered that internalized cultural worldviews might affect network composition. Drawing on a synthetic, dual-process theory of culture and two waves of nationally-representative panel data, this article…

Partial wave analysis of anti pp → anti ΛΛ

2004-01-01

A partial wave analysis of PS185 data for anti pp → anti ΛΛ is presented. A 3 S 1 cusp is identified in the inverse process anti ΛΛ→ anti p p at threshold, using detailed balance to deduce cross sections from anti pp → anti ΛΛ. Partial wave amplitudes for anti pp 3 P 0 , 3 F 3 , 3 D 3 and 3 G 3 exhibit a behaviour very similar to resonances observed in Crystal Barrel data. With this identification, the anti pp → anti ΛΛ data then provide evidence for a new I=0, J PC =1 - resonance with mass M = 2290 ±20 MeV, Γ= 275 ±35 MeV, coupling to both 3 S 1 and 3 D 1 . (orig.)

Full Text Available Cross-linked polyethylene (XLPE is a thermosetting material that cannot be recycled at the end of its lifetime. This study investigated the potential of syndiotactic polypropylene (sPP/silica as an ecofriendly extruded insulation system for HVDC cables. We investigated the morphology, Fourier transform infrared, and thermal, thermomechanical, and electrical behaviors of sPP modified with 0.5–3% nanosilica. We found that the silica/sPP nanocomposite without cross-linking offered a suitable mechanical modulus at room temperature and sufficient intensity at high temperatures, and adding nanosilica modified by a silane coupling agent to the sPP resulted in significant DC resistivity and space charge improvement. The optimal nanosilica content in the sPP was determined by balancing the mechanical and thermomechanical characteristics and the DC resistivity. The sPP/silica nanocomposite reported here shows great potential as a candidate insulation material for future ecofriendly extruded HVDC cables.

The morphology of i-PP with different isotacticity under high absorbed dose were studied with the measurements of crystallinity, crystallite size, melting heat and melting point by x-ray diffraction and DSC methods respectively. The results indicate that the changes are not only related to the heat history but also related to the isotacticity of i-PP. In generally, the higher the isotacticity of i-PP, the less morphology changes, and the morphology of annealing samples change less than the virgin powder samples. It means that the annealed i-PP with higher isotacticity is more stable to radiation both in air and vacuum conditions. (author)

Creativity, innovation, and entrepreneurship across cultures theory and practices

Carayannis, Elias

2016-01-01

The aim of this volume is to further develop the relationship between culture and manifold phenomena of creativity, innovation and entrepreneurship in order to promote further and better understanding how, why, and when these phenomena are manifested themselves across different cultures.   Currently, cross-cultural research is one of the most dynamically and rapidly growing areas. At the same time, creativity, inventiveness, innovation, and entrepreneurship are championed in the literature as the critical element that is vital not just for companies, but also for the development of societies. A sizable body of research demonstrates that cultural differences may foster or inhibit creative, inventive, innovative and entrepreneurial activities; and each culture has its own strengths and weaknesses in these regards.  Better understanding of cultural diversity in these phenomena can help to build on strengths and overcome weaknesses.   Cross-cultural studies in this field represent a comparatively new class of ...

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

Also, according to the theory of life style and intergenerational transmission of cultural capital, some insights are presented on the Future of the consumption of caltural products in Iranian society.

The Basic Social Process in the Culture of the Self-Sufficient Organization. An Application of Grounded Theory

Full Text Available The hereby research encompasses the results of an analysis conducted based on the grounded theory methodology over the qualitative data that were gathered through a national project regarding the organizational development of the mental health institutions. After the finalization of the project, the interest for the grounded theory methodology and the reconsideration of the organizational development notion and of the role of the consultant in this process have all lead to a re-analysis of the qualitative data procured in one of the hospitals included in the project. Our approach resulted in an explanatory model of how the organization works and the factors that can affect various changes during its development. This explanatory model holds at its center a basic psychological and social process that represents the perception of the organizational system as closed on certain coordinates, although structurally open. This very perception and the behavior of maintaining the system within closed coordinates allow only for a dual functioning and so the natural result is the emergence of a self-sufficient culture. The central feature of this particular culture is the replacement of the formal organization and its goal of caring for the mentally challenged with an organization reduced to its sole goal of survival.

Causal beliefs about depression in different cultural groups – What do cognitive psychological theories of causal learning and reasoning predict?

2014-11-01

Full Text Available Cognitive psychological research focusses on causal learning and reasoning while cognitive anthropological and social science research tend to focus on systems of beliefs. Our aim was to explore how these two types of research can inform each other. Cognitive psychological theories (causal model theory and causal Bayes nets were used to derive predictions for systems of causal beliefs. These predictions were then applied to lay theories of depression as a specific test case. A systematic literature review on causal beliefs about depression was conducted, including original, quantitative research. Thirty-six studies investigating 13 non-Western and 32 Western cultural groups were analysed by classifying assumed causes and preferred forms of treatment into common categories. Relations between beliefs and treatment preferences were assessed. Substantial agreement between cultural groups was found with respect to the impact of observable causes. Stress was generally rated as most important. Less agreement resulted for hidden, especially supernatural causes. Causal beliefs were clearly related to treatment preferences in Western groups, while evidence was mostly lacking for non-Western groups. Overall predictions were supported, but there were considerable methodological limitations. Pointers to future research, which may combine studies on causal beliefs with experimental paradigms on causal reasoning, are given.

Full Text Available Different genres of underground music are important issues in Iranian youth culture. The purpose of this research was to study masculinity in Iranian- Persian rap music. Therefore, Persian rap music as a part of Iranian popular culture, between 2001 and 2011 was analyzed. We used qualitative research approach. The main method used in this study, was "Constructive Grounded Theory ". So instead of using existing theories as a theoretical framework, the researcher sought to generate local theory from research field. Thus, using theoretical sampling, data compiled from various sources. The multiple data collection techniques such as interviews, observation, online observation, collecting documents and texts were used. Then all the data was coded with using open, axial and selective coding methods. Finally, 62 concepts and 16 categories derived from data and "plural form of masculinity in Iranian-Persian rap music" was defined as the core category. Then according to paradigmatic model, "Substantive Theory" emerged from the data, was presented as "story" and "visual model". Finally seven questions of Strauss and Corbin about the experience in research has been assessed to evaluating research.

Sociocultural Theory and its Role in the Development of Language Pedagogy

Abdul Hameed Panhwar

2016-12-01

Full Text Available This paper reviews the literature on Vygotskian theory of Socio-cultural learning and constructivist approach to teaching and learning and attempts to relate the socio-cultural theory to constructivism. The purpose of the paper is to investigate the ways socio-cultural theory helps to develop language pedagogies. Critical analysis of the literature on the socio-cultural theory suggests that the theory has potential for forming new context-oriented language teaching-learning pedagogies which can help teachers in maximising the effectiveness of their teaching and their student’s learning. The review further suggests that the language pedagogies and activities developed from the sociocultural theory of Vygotsky may not only improve students’ language skills, but it also has potential to develop students’ cognition. Since theory promotes more and more communication of students with each other through scaffolding, that is, the Zone of Proximal development (ZPD in Vygotsky’s language. Thus, the theory directly points towards the promotion of student-centred learning by establishing learner autonomy. Keywords: socio-cultural theory, language, constructivism, pedagogies, students
