Sample records for directional cultural change

  1. Directional cultural change by modification and replacement of memes.

    Cardoso, Gonçalo C; Atwell, Jonathan W

    2011-01-01

    Evolutionary approaches to culture remain contentious. A source of contention is that cultural mutation may be substantial and, if it drives cultural change, then current evolutionary models are not adequate. But we lack studies quantifying the contribution of mutations to directional cultural change. We estimated the contribution of one type of cultural mutations--modification of memes--to directional cultural change using an amenable study system: learned birdsongs in a species that recently entered an urban habitat. Many songbirds have higher minimum song frequency in cities, to alleviate masking by low-frequency noise. We estimated that the input of meme modifications in an urban songbird population explains about half the extent of the population divergence in song frequency. This contribution of cultural mutations is large, but insufficient to explain the entire population divergence. The remaining divergence is due to selection of memes or creation of new memes. We conclude that the input of cultural mutations can be quantitatively important, unlike in genetic evolution, and that it operates together with other mechanisms of cultural evolution. For this and other traits, in which the input of cultural mutations might be important, quantitative studies of cultural mutation are necessary to calibrate realistic models of cultural evolution. © 2010 The Author(s).

  3. Accelerating the culture change!

    Klunk, S W; Panetta, J; Wooten, J

    1996-11-01

    Exide Electronics, a major supplier of uninterruptible power system equipment, embarked on a journey of changing a culture to improve quality, enhance customer responsiveness, and reduce costs. This case study examines the evolution of change over a period of seven years, with particular emphasis on the most recent years, 1992 through 1995. The article focuses on the Raleigh plant operations and describes how each succeeding year built on the successes and fixed the shortcomings of the prior years to accelerate the culture change, including corrective action and continuous improvement processes, organizational structures, expectations, goals, achievements, and pitfalls. The real challenge to changing the culture was structuring a dynamic approach to accelerate change! The presentation also examines how the evolutionary process itself can be created and accelerated through ongoing communication, regular feedback of progress and goals, constant evaluation and direction of the process, and measuring and paying for performance.

  4. Family support for the elderly in Korea: continuity, change, future directions, and cross-cultural concerns.

    Sung, K T

    2001-01-01

    This article discusses major issues and concerns regarding family support for parents and elderly people in industrialized and urbanized Korea. It summarizes new trends in family support for elderly members, continuing influences of the traditional value of family support (filial piety), growing needs for public services for elderly people and their families, urgent calls for the state to assume greater responsibilities for providing social security and services for the elderly, needs for cross-cultural studies of family support, and certain cultural similarities and differences to be considered. The article concludes with some suggestions for future research.

  5. Darwinism and cultural change.

    Godfrey-Smith, Peter

    2012-08-05

    Evolutionary models of cultural change have acquired an important role in attempts to explain the course of human evolution, especially our specialization in knowledge-gathering and intelligent control of environments. In both biological and cultural change, different patterns of explanation become relevant at different 'grains' of analysis and in contexts associated with different explanatory targets. Existing treatments of the evolutionary approach to culture, both positive and negative, underestimate the importance of these distinctions. Close attention to grain of analysis motivates distinctions between three possible modes of cultural evolution, each associated with different empirical assumptions and explanatory roles.

  6. Culture and change blindness.

    Masuda, Takahiko; Nisbett, Richard E

    2006-03-04

    Research on perception and cognition suggests that whereas East Asians view the world holistically, attending to the entire field and relations among objects, Westerners view the world analytically, focusing on the attributes of salient objects. These propositions were examined in the change-blindness paradigm. Research in that paradigm finds American participants to be more sensitive to changes in focal objects than to changes in the periphery or context. We anticipated that this would be less true for East Asians and that they would be more sensitive to context changes than would Americans. We presented participants with still photos and with animated vignettes having changes in focal object information and contextual information. Compared to Americans, East Asians were more sensitive to contextual changes than to focal object changes. These results suggest that there can be cultural variation in what may seem to be basic perceptual processes. 2006 Lawrence Erlbaum Associates, Inc.

  8. Cultural Change: The How and the Why.

    Varnum, Michael E W; Grossmann, Igor

    2017-11-01

    More than half a century of cross-cultural research has demonstrated group-level differences in psychological and behavioral phenomena, from values to attention to neural responses. However, cultures are not static, with several specific changes documented for cultural products, practices, and values. How and why do societies change? Here we juxtapose theory and insights from cultural evolution and social ecology. Evolutionary approaches enable an understanding of the how of cultural change, suggesting transmission mechanisms by which the contents of culture may change. Ecological approaches provide insights into the why of cultural change: They identify specific environmental pressures, which evoke shifts in psychology and thereby enable greater precision in predictions of specific cultural changes based on changes in ecological conditions. Complementary insights from the ecological and cultural evolutionary approaches can jointly clarify the process by which cultures change. We end by discussing the relevance of cultural change research for the contemporary societal shifts and by highlighting several critical challenges and future directions for the emerging field of cross-temporal research on culture and psychology.

    The paper presents a novel concept that analyzes and visualizes worldwide fashion trends. Our goal is to reveal cutting-edge fashion trends without displaying an ordinary fashion style. To achieve the fashion-based analysis, we created a new fashion culture database (FCDB), which consists of 76 million geo-tagged images in 16 cosmopolitan cities. By grasping a fashion trend of mixed fashion styles,the paper also proposes an unsupervised fashion trend descriptor (FTD) using a fashion descripto...

  12. Culture, mind, and the brain: current evidence and future directions.

    Kitayama, Shinobu; Uskul, Ayse K

    2011-01-01

    Current research on culture focuses on independence and interdependence and documents numerous East-West psychological differences, with an increasing emphasis placed on cognitive mediating mechanisms. Lost in this literature is a time-honored idea of culture as a collective process composed of cross-generationally transmitted values and associated behavioral patterns (i.e., practices). A new model of neuro-culture interaction proposed here addresses this conceptual gap by hypothesizing that the brain serves as a crucial site that accumulates effects of cultural experience, insofar as neural connectivity is likely modified through sustained engagement in cultural practices. Thus, culture is "embrained," and moreover, this process requires no cognitive mediation. The model is supported in a review of empirical evidence regarding (a) collective-level factors involved in both production and adoption of cultural values and practices and (b) neural changes that result from engagement in cultural practices. Future directions of research on culture, mind, and the brain are discussed.

  13. Leadership, Culture and Organizational Change

    Vladimir-Codrin Ionescu

    2014-12-01

    Full Text Available An effective leadership, an evolutionary organizational culture and permanent connection to change may ensure a company’s success within an ever more dynamic competitive environment. The scientific approach of this paper is in line with theoretical and applied research in the field by the presentation of the connections existing among leadership, organizational culture and organizational change. The paper highlights the triad “vision – motivation – momentum”, the mission and the defining coordinates of leadership, the complementarity “new – tradition” in organizational culture, the stages of the change management process and the role of managers and leaders in the preparation and implementation of change projects. Leadership is essential in building and developing an appropriate cultural model, which, in its turn, is an important vector of organizational change processes in modern companies.

  17. Culture and cognition in health systems change.

    Evans, Jenna M; Baker, G Ross; Berta, Whitney; Barnsley, Jan

    2015-01-01

    Large-scale change involves modifying not only the structures and functions of multiple organizations, but also the mindsets and behaviours of diverse stakeholders. This paper focuses on the latter: the informal, less visible, and often neglected psychological and social factors implicated in change efforts. The purpose of this paper is to differentiate between the concepts of organizational culture and mental models, to argue for the value of applying a shared mental models (SMM) framework to large-scale change, and to suggest directions for future research. The authors provide an overview of SMM theory and use it to explore the dynamic relationship between culture and cognition. The contributions and limitations of the theory to change efforts are also discussed. Culture and cognition are complementary perspectives, providing insight into two different levels of the change process. SMM theory draws attention to important questions that add value to existing perspectives on large-scale change. The authors outline these questions for future research and argue that research and practice in this domain may be best served by focusing less on the potentially narrow goal of "achieving consensus" and more on identifying, understanding, and managing cognitive convergences and divergences as part of broader research and change management programmes. Drawing from both cultural and cognitive paradigms can provide researchers with a more complete picture of the processes by which coordinated action are achieved in complex change initiatives in the healthcare domain.

  18. How directional change in reading/writing habits relates to directional change in displayed pictures.

    Lee, Hachoung; Oh, Songjoo

    2016-01-01

    It has been suggested that reading/writing habits may influence the appreciation of pictures. For example, people who read and write in a rightward direction have an aesthetic preference for pictures that face rightward over pictures that face leftward, and vice versa. However, correlations for this phenomenon have only been found in cross-cultural studies. Will a directional change in reading/writing habits within a culture relate to changes in picture preference? Korea is a good place to research this question because the country underwent gradual changes in reading/writing direction habits, from leftward to rightward, during the 20th century. In this study, we analyzed the direction of drawings and photos published in the two oldest newspapers in Korea from 1920-2013. The results show that the direction of the drawings underwent a clear shift from the left to the right, but the direction of the photos did not change. This finding suggests a close psychological link between the habits of reading/writing and drawing that cannot be accounted for simply by an accidental correspondence across different cultures.

  20. Cultural Synergy and Organizational Change

    Strøbæk, Pernille Solveig; Vogt, Joachim

    2013-01-01

    This paper explores informal codes and rhythms of social behavior at work and their relation to organizational change and wellbeing. After a merger within a public service organization we organized 8 focus groups of 2-3 clerical or academic employees within a head office and a division office (N...... = 21). Word counts of ‘I’ and ‘we’ revealed that people sharing pre-merger organizational background (homogeneous groups) used ‘we’ more often than heterogeneous groups. Head office employees were concerned with workload and social code, whereas division office employees mainly discussed meetings......, commitment, and office space. Organizational background rather than office cultures guided these differences. We found that in a merged organization cultural synergies are possible to create if practical and social values for employees are offered. Thus, interesting new ways to transform problems...

  1. Direct short-term effects of EBP teaching: change in knowledge, not in attitude; a cross-cultural comparison among students from European and Asian medical schools

    Indah S. Widyahening

    2012-10-01

    Full Text Available Introduction: We report about the direct short-term effects of a Clinical Epidemiology and Evidence-based Medicine (CE-EBM module on the knowledge, attitude, and behavior of students in the University Medical Center Utrecht (UMCU, Universitas Indonesia (UI, and University of Malaya (UM. Methods: We used an adapted version of a 26-item validated questionnaire, including four subscales: knowledge, attitude, behavior, and future use of evidence-based practice (EBP. The four components were compared among the students in the three medical schools before the module using one-way ANOVA. At the end of the module, we measured only knowledge and attitudes. We computed Cronbach's α to assess the reliability of the responses in our population. To assess the change in knowledge and attitudes, we used the paired t-test in the comparison of scores before and after the module. Results: In total, 526 students (224 UI, 202 UM, and 100 UMCU completed the questionnaires. In the three medical schools, Cronbach's α for the pre-module total score and the four subscale scores always exceeded 0.62. UMCU students achieved the highest pre-module scores in all subscales compared to UI and UM with the comparison of average (SD score as the following: knowledge 5.04 (0.4 vs. 4.73 (0.69 and 4.24 (0.74, p<0.001; attitude 4.52 (0.64 vs. 3.85 (0.68 and 3.55 (0.63, p<0.001; behavior 2.62 (0.55 vs. 2.35 (0.71 and 2.39 (0.92, p=0.016; and future use of EBP 4.32 (0.59 vs. 4.08 (0.62 and 3.7 (0.71, p<0.01. The CE-EBM module increased the knowledge of the UMCU (from average 5.04±0.4 to 5.35±0.51; p<0.001 and UM students (from average 4.24±0.74 to 4.53±0.72; p<0.001 but not UI. The post-module scores for attitude did not change in the three medical schools. Conclusion: EBP teaching had direct short-term effects on knowledge, not on attitude. Differences in pre-module scores are most likely related to differences in the system and infrastructure of both medical schools and their

  4. Cultural innovations and demographic change.

    Richerson, Peter J; Boyd, Robert; Bettinger, Robert L

    2009-04-01

    Demography plays a large role in cultural evolution through its effects on the effective rate of innovation. If we assume that useful inventions are rare, then small isolated societies will have low rates of invention. In small populations, complex technology will tend to be lost as a result of random loss or incomplete transmission (the Tasmanian effect). Large populations have more inventors and are more resistant to loss by chance. If human populations can grow freely, then a population-technology-population positive feedback should occur such that human societies reach a stable growth path on which the rate of growth of technology is limited by the rate of invention. This scenario fits the Holocene to a first approximation, but the late Pleistocene is a great puzzle. Large-brained hominins existed in Africa and west Eurasia for perhaps 150,000 years with, at best, slow rates of technical innovation. The most sophisticated societies of the last glacial period appear after 50,000 years ago and were apparently restricted to west and north-central Eurasia and North Africa. These patterns have no simple, commonly accepted explanation. We argue that increased high-frequency climate change around 70,000-50,000 years ago may have tipped the balance between humans and their competitor-predators, such as lions and wolves, in favor of humans. At the same time, technically sophisticated hunters would tend to overharvest their prey. Perhaps the ephemeral appearance of complex tools and symbolic artifacts in Africa after 100,000 years ago resulted from hunting inventions that allowed human populations to expand temporarily before prey overexploitation led to human population and technology collapse. Sustained human populations of moderate size using distinctively advanced Upper Paleolithic artifacts may have existed in west Eurasia because cold, continental northeastern Eurasia-Beringia acted as a protected reserve for prey populations.

  5. Vulnerable populations: cultural and spiritual direction.

    Quest, Tammie E; Franks, Nicole M

    2006-08-01

    Cultural, spiritual, and religious diversity of emergency department patients is increasing while that of emergency physicians in particular remains predominantly homogeneous. With a discordance of cultural, race, and ethnicity exist, in the case of ethical conflict -resolution becomes that much more difficult. Patients may feel vulnerable when their emergency care provider does not understand his or her cultural, spiritual, and religious uniqueness as it relates to the patient-doctor interaction and health care decision making. This review will examine (1) language differences; (2) cultural, religious, and spiritual differences between patient and provider; (3) differing explanatory models of disease between patient and provider; and (4) diverse bioethical models of decision making of differing cultures in an effort to reduce vulnerabilities.

  6. Culture and hallucinations: overview and future directions.

    Larøi, Frank; Luhrmann, Tanya Marie; Bell, Vaughan; Christian, William A; Deshpande, Smita; Fernyhough, Charles; Jenkins, Janis; Woods, Angela

    2014-07-01

    A number of studies have explored hallucinations as complex experiences involving interactions between psychological, biological, and environmental factors and mechanisms. Nevertheless, relatively little attention has focused on the role of culture in shaping hallucinations. This article reviews the published research, drawing on the expertise of both anthropologists and psychologists. We argue that the extant body of work suggests that culture does indeed have a significant impact on the experience, understanding, and labeling of hallucinations and that there may be important theoretical and clinical consequences of that observation. We find that culture can affect what is identified as a hallucination, that there are different patterns of hallucination among the clinical and nonclinical populations, that hallucinations are often culturally meaningful, that hallucinations occur at different rates in different settings; that culture affects the meaning and characteristics of hallucinations associated with psychosis, and that the cultural variations of psychotic hallucinations may have implications for the clinical outcome of those who struggle with psychosis. We conclude that a clinician should never assume that the mere report of what seems to be a hallucination is necessarily a symptom of pathology and that the patient's cultural background needs to be taken into account when assessing and treating hallucinations. © The Author 2014.

  8. CHANGING ORGANIZATIONAL CULTURE IN A ROMANIAN COMPANY

    CRIVEANU Maria Magdalena

    2016-08-01

    Full Text Available The focus on studying the issue of change, migrated from the attention towards western countries, struggling with the growing spread of globalization, which affects all the changes in the environment, to the former socialist countries of Central and Eastern Europe, which have undergone dramatic changes since 1989. The most disturbing event was the transition from the centralized economy system to the market economy system, which led to a series of mutations at both psychological and organizational level. In this context, this article aims to identify both the dominant type of culture in the largest retail company in Romania and the dominant type of culture in other similar companies. This research project aims at studying the culture and its specificity within the company, but also its impact on society and on the organization. The issue at stake is a retail company in Romania, in which we tried to identify the dominant culture within the company and culture desired by its employees. We also conducted a parallel between the culture type identified in the Romanian company and the type of culture identified in other companies. The research results can be a starting point for the manager charged with change, as he can easily identify discrepancies between the dominant culture and culture desired by employees

    The Islamic Revolution of 1979, the 8-year war with Iraq (1980-88), and the collapse of oil prices in 1986 dealt huge blows to Iran's economy. In this article, we use a pseudopanel constructed from annual multiple surveys during 1984-2004 to analyze changes in cohort earnings and consumption through these tumultuous times. Using well-known techniques, we decompose the changes in median cohort earnings of men into cohort, age, and year effects. Our results show that cohorts born before 1950, w...

  11. Parent socialization effects in different cultures: significance of directive parenting.

    Sorkhabi, Nadia

    2012-06-01

    In this article, the controversy of divergent findings in research on parental socialization effects in different cultures is addressed. Three explanations intended to address divergent findings of socialization effects in different cultures, as advanced by researchers who emphasize cultural differences, are discussed. These include cultural differences in socialization values and goals of parents, parental emotional and cognitive characteristics associated with parenting styles, and adolescents' interpretations or evaluations of their parents' parenting styles. The empirical evidence for and against each of these arguments is examined and an alternative paradigm for understanding and empirical study of developmental outcomes associated with parenting styles in different cultures is suggested. Baumrind's directive parenting style is presented as an alternative to the authoritarian parenting style in understanding the positive developmental effects associated with "strict" parenting in cultures said to have a collectivist orientation. Directions for research on the three explanations are mentioned.

  12. Processes and driving forces in changing cultural landscapes across Europe

    2017-01-01

    Context: Cultural landscapes evolve over time. However, the rate and direction of change might not be in line with societal needs and more information on the forces driving these changes are therefore needed. Objectives: Filling the gap between single case studies and meta-analyses, we present...... perceived landscape changes, and remembered driving forces. Land cover and landscape changes were analysed regarding change, conversions and processes. For all case study areas, narratives on mapped land cover change, perceived landscape changes and driving forces were compiled. Results: Despite a very high...... diversity in extent, direction and rates of change, a few dominant processes and widespread factors driving the changes could be identified in the six case study areas, i.e. access and infrastructure, political shifts, labor market, technological innovations, and for the more recent period climate change...

  13. Implementing Culture Change in Nursing Homes: An Adaptive Leadership Framework.

    Corazzini, Kirsten; Twersky, Jack; White, Heidi K; Buhr, Gwendolen T; McConnell, Eleanor S; Weiner, Madeline; Colón-Emeric, Cathleen S

    2015-08-01

    To describe key adaptive challenges and leadership behaviors to implement culture change for person-directed care. The study design was a qualitative, observational study of nursing home staff perceptions of the implementation of culture change in each of 3 nursing homes. We conducted 7 focus groups of licensed and unlicensed nursing staff, medical care providers, and administrators. Questions explored perceptions of facilitators and barriers to culture change. Using a template organizing style of analysis with immersion/crystallization, themes of barriers and facilitators were coded for adaptive challenges and leadership. Six key themes emerged, including relationships, standards and expectations, motivation and vision, workload, respect of personhood, and physical environment. Within each theme, participants identified barriers that were adaptive challenges and facilitators that were examples of adaptive leadership. Commonly identified challenges were how to provide person-directed care in the context of extant rules or policies or how to develop staff motivated to provide person-directed care. Implementing culture change requires the recognition of adaptive challenges for which there are no technical solutions, but which require reframing of norms and expectations, and the development of novel and flexible solutions. Managers and administrators seeking to implement person-directed care will need to consider the role of adaptive leadership to address these adaptive challenges. © The Author 2014.

  15. Culture, Urbanism and Changing Human Biology.

    Schell, L M

    2014-04-03

    Anthropologists have long known that human activity driven by culture changes the environment. This is apparent in the archaeological record and through the study of the modern environment. Perhaps the largest change since the paleolithic era is the organization of human populations in cities. New environments can reshape human biology through evolution as shown by the evolution of the hominid lineage. Evolution is not the only process capable of reshaping our biology. Some changes in our human biology are adaptive and evolutionary while others are pathological. What changes in human biology may be wrought by the modern urban environment? One significant new change in the environment is the introduction of pollutants largely through urbanization. Pollutants can affect human biology in myriad ways. Evidence shows that human growth, reproduction, and cognitive functioning can be altered by some pollutants, and altered in different ways depending on the pollutant. Thus, pollutants have significance for human biologists and anthropologists generally. Further, they illustrate the bio-cultural interaction characterizing human change. Humans adapt by changing the environment, a cultural process, and then change biologically to adjust to that new environment. This ongoing, interactive process is a fundamental characteristic of human change over the millennia.

    2016-01-01

    The questions addressed by this review are: first, what are the guiding principles underlying efforts to stimulate sustained cultural change; second, what are the mechanisms by which these principles operate; and, finally, what are the contextual factors that influence the likelihood of these principles being effective? The paper aims to discuss these issues. The authors conducted a literature review informed by rapid realist review methodology that examined how interventions interact with contexts and mechanisms to influence the sustainability of cultural change. Reference and expert panelists assisted in refining the research questions, systematically searching published and grey literature, and helping to identify interactions between interventions, mechanisms and contexts. Six guiding principles were identified: align vision and action; make incremental changes within a comprehensive transformation strategy; foster distributed leadership; promote staff engagement; create collaborative relationships; and continuously assess and learn from change. These principles interact with contextual elements such as local power distributions, pre-existing values and beliefs and readiness to engage. Mechanisms influencing how these principles sustain cultural change include activation of a shared sense of urgency and fostering flexible levels of engagement. The principles identified in this review, along with the contexts and mechanisms that influence their effectiveness, are useful domains for policy and practice leaders to explore when grappling with cultural change. These principles are sufficiently broad to allow local flexibilities in adoption and application. This is the first study to adopt a realist approach for understanding how changes in organizational culture may be sustained. Through doing so, this review highlights the broad principles by which organizational action may be organized within enabling contextual settings.

  17. A "recipe" for culture change? Findings from the THRIVE survey of culture change adopters.

    Elliot, Amy; Cohen, Lauren W; Reed, David; Nolet, Kimberly; Zimmerman, Sheryl

    2014-02-01

    Descriptions of culture change adoption are often complex and varied, creating a challenge for those seeking guidance about which of the many components of culture change to adopt and in what order and combination. To begin to address this question, members of The Research Initiative Valuing Eldercare (THRIVE) developed and distributed an online survey to 327 known culture change adopters. Of these, 164 (50%) completed the survey. Data were analyzed to identify adopted components, co-occurrence of adopted components, and differences in these across various types of nursing home models (i.e., traditional unit, household, and small house). Our findings support unique co-occurrence of components across nursing home models. Results also show that homes with more traditional environments have been able to implement certain culture change components without large capital investments required by renovations. The adoption patterns suggest that the co-occurrence of components should be considered when pursuing organizational transformations to support culture change.

  18. Climate change, values, and the cultural cognition thesis

    Persson, Johannes; Sahlin, Nils-Eric; Wallin, Annika

    2015-01-01

    Recently the importance of addressing values in discussions of risk perception and adaptation to climate change has become manifest. Values-based approaches to climate change adaptation and the cultural cognition thesis both illustrate this trend. We argue that in the wake of this development it is necessary to take the dynamic relationship between values and beliefs seriously, to acknowledge the possibility of bi-directional relationships between values and beliefs, and to address the variet...

  19. Ultraviolet radiation directly induces pigment production by cultured human melanocytes

    Friedmann, P.S.; Gilchrest, B.A.

    1987-01-01

    In humans the major stimulus for cutaneous pigmentation is ultraviolet radiation (UVR). Little is known about the mechanism underlying this response, in part because of the complexity of interactions in whole epidermis. Using a recently developed culture system, human melanocytes were exposed daily to a physiologic range of UVR doses from a solar simulator. Responses were determined 24 hours after the last exposure. There was a dose-related increase in melanin content per cell and uptake of 14 C-DOPA, accompanied by growth inhibition. Cells from donors of different racial origin gave proportionately similar increases in melanin, although there were approximately tenfold differences in basal values. Light and electron microscopy revealed UVR-stimulated increases in dendricity as well as melanosome number and degree of melanization, analogous to the well-recognized melanocyte changes following sun exposure of intact skin. Similar responses were seen with Cloudman S91 melanoma cells, although this murine cell line required lower UVR dosages and fewer exposures for maximal stimulation. These data establish that UVR is capable of directly stimulating melanogenesis. Because cyclic AMP elevation has been associated in some settings with increased pigment production by cultured melanocytes, preliminary experiments were conducted to see if the effects of UVR were mediated by cAMP. Both alpha-MSH and isobutylmethylxanthine (IBMX), as positive controls, caused a fourfold increase in cAMP level in human melanocytes and/or S91 cells, but following a dose of UVR sufficient to stimulate pigment production there was no change in cAMP level up to 4 hours after exposure. Thus, it appears that the UVR-induced melanogenesis is mediated by cAMP-independent mechanisms

    Full Text Available Permanently unsolved world food insecurity problem makes the international community search for solutions. One of the used methods is international food aid directed to developing countries. Long term analyses of the food aid flows allow to identify some tendencies that show: increase of emergency food aid and decrease of direct transfer. These tendencies also apply to the two biggest food donors i.e. the USA and the EU. The noticeable directions of changes are based on the international community initiatives, on which the national regulation are formed later.

  3. Culture Negative Infective Endocarditits: a Changing Paradigm

    Daly, A

    2016-05-01

    Traditionally, the modified Duke\\'s criteria, based primarily on positive blood cultures, is used to diagnose Infective Endocarditis (IE). However, reports demonstrate that 31% of cases are diagnosed as Culture Negative Infective Endocarditis (CNIE)1. Consequently, empiric broad-spectrum antibiotics are prescribed to cover unidentified organisms and, as a result, antibiotic therapy may be compromised. Molecular diagnostic techniques aid with identifying causative organisms in cases of CNIE and we question if the increasing use of such technologies will change the local epidemiology of CNIE. We present the first case of Tropheryma whipplei Infective Endocarditis (TWIE) reported in Ireland.

  4. Folk Beliefs of Cultural Changes in China

    Yi eXu

    2014-09-01

    Full Text Available For the last several decades, Chinese society has experienced transformative changes. How are these changes understood among Chinese people? To examine this question, Part 1 in this research solicited folk beliefs of cultural change from a group of Chinese participants in an open-ended format, and the generated folk beliefs were rated by another group of participants in Part 2 to gauge each belief’s level of agreement. Part 3 plotted the folk beliefs retained in Part 2 using the Google Ngram Viewer in order to infer the amount of intellectual interests that each belief has received cross-temporarily. These analyses suggested a few themes in Chinese folk beliefs of cultural change (1 rising perceived importance of materialism and individualism in understanding contemporary Chinese culture and Chinese psychology relative to those of the past (2 rising perceived importance of freedom, democracy and human rights and (3 enduring perceived importance of family relations and friendship as well as patriotism. Interestingly, findings from Parts 2 and 3 diverged somewhat, illuminating possible divergence between folk beliefs and intellectual interests especially for issues related to heritage of Confucianism.

  5. Direct broadcast of a sporting event as televisual cultural form

    Full Text Available Direct TV broadcasting of sport events is undoubtedly the focal point of interest of sport fans in sports media as well as of sponsors and investors responsible for the global mediatisation of popular sports. In this article, the centrality of direct TV broadcasts in the televisual coverage of sports, as well as in the presence of sports in new media in general is explained in the context of the impact of the mediatisation of sports upon cultural forms of TV coverage of sports. The complexity of these forms and its main features (the role of the commentator, the rules of editing, dramatisation and narrativisation in direct broadcasts are analysed.

    This special issue addresses a topic of journalism studies that has previously been somewhat neglected but which has gained increasing scholarly attention since the mid-2000s: the coverage and evaluation of art and culture, or what we term “cultural journalism and cultural critique.......” In this introduction, we highlight three issues that serve to frame the study of cultural journalism and cultural critique more generally and the eight articles of this special issue more specifically: (1) the constant challenge of demarcating cultural journalism and cultural critique, including the interrelations...... of “journalism” and “critique”; (2) the dialectic of globalisation’s cultural homogenisation, on the one hand, and the specificity of local/national cultures, on the other; and (3) the digital media landscape seen in terms of the need to rethink, perhaps even redefine cultural journalism and cultural critique...

  7. Cultural influence on directional tendencies in children's drawing.

    Portex, Marine; Foulin, Jean-Noël; Troadec, Bertrand

    2017-09-01

    The present study was aimed at investigating how print experience as a cultural factor influences directional tendencies in children's drawing in the interplay with biomechanical (hand), syntactic (shape orientation) and semantic (shape meaning) factors. Eighty-eight right-handed children from three literacy/age groups (preliterate, first graders and third graders) had to copy a geometrical shape adapted from the Rey-Osterrieth complex figure. The shape was presented alternatively leftward and rightward, while using both dominant (right) and non-dominant (left) hands. Directional tendencies were assessed regarding directionality of drawing movements at global, intermediate and local levels and deviation error in centre line bisection. Results show a global improvement of drawing quality and strategies across groups and an advantage for the dominant right hand from 6 years onward. Regarding directional tendencies, a reinforcement of a congruency effect between conditions and writing direction was found from preliterates to third graders. These results are discussed as a cultural embodiment process and have implications for psychological testing.

  11. Population growth, demographic change, and cultural landscapes.

    Woodgate, G; Sage, C

    1994-01-01

    The inclusion of both ecological and socioeconomic components within landscapes makes possible the perception of the hierarchical character of landscape organization. A research approach is needed to conceptualize cultural landscapes as the product of interaction between society and nature. Richard Norgaard's 1984 paper on coevolutionary agricultural development attempts to meet this challenge. Coevolution is the interactive synthesis of natural and social mechanisms of change that characterize the relationship between social systems and ecosystems. The relationship between population, consumption, and environmental changes is complex. Currently industrialized countries present the biggest threat to global environmental resources. The issue of carrying capacity is the corollary of population and the environment. It is primarily the technological factor rather than population that needs to be controlled. The relationship between rich and poor countries is determined by superior economic power. An analysis of landscape change is made, tracing the coevolution of society and environment from the end of the feudal era and making comparisons with continental Europe. Over the years since 1945 the need to realize potential economies of scale has resulted in a wholesale loss of woodlands, hedgerows, and small ponds in the UK. In a global context the likely impacts of population growth and demographic change on landscapes will be influenced by such socioeconomic factors as technology and affluence; policies that ignore cause and effect; and the traditional tendency to treat the environment as a waste repository and a supply depot.

  12. Liquid modern journalism with a difference : The changing professional ethos of cultural journalism

    Jaakkola, Maarit; Hellman, Heikki; Koljonen, Kari; Väliverronen, Jari

    2015-01-01

    Reflecting a change from high to liquid modern culture, journalism is said to be encountering a transformation from high toward liquid modernity. Cultural journalism, however, has been found to be "journalism with a difference". Due to this distinctive character, the principles of general journalism do not directly apply to cultural journalism. Consequently, the manifestations and consequences of the high and liquid modern ethos appear differently in cultural journalism. Proposing a theoretic...

  13. Reliability of direct sensitivity determination of blood cultures

    Noman, F.; Ahmed, A.

    2008-01-01

    The aim of this study was to evaluate the error in interpreting antimicrobial sensitivity by direct method when compared to standard method and find out if specific antibiotic-organism combination had more discrepancies. All blood culture samples received at Microbiology Laboratory from 1st July 2006 to 31st August 2006 were ncluded in the study. All samples were inoculated in automated blood culture system BACTEC 9240 which contained enriched Soybean-Casein Digest broth with CO/sub 2/. Once positive, bottles were removed from system; gram staining of the positive broths was done. Susceptibility test was performed from positive broth, on MHA (Mueller-Hinton Agar), with antibiotics panel according to gram stain result. All positive broths were also sub-cultured on blood agar, chocolate agar and McConkey agar for only gram-negative rods. Next day, the zone sizes of all antibiotics were recorded using measuring scale and at the same time susceptibility test was repeated from isolated colonies from subcultures, with inoculums prepared of McFarland 0.5 standard 0.2 Staphylococcus aureus (ATCC 29213); E.coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 27853) were included as quality control strain. Zone sizes were interpreted as sensitive (S), resistant (R) and intermediate (I) according to CLSI recommendation. Two results were compared and recorded. Out of a total 1083 combinations, zone diameters by standard method were either equal or greater than direct zone diameter (never smaller). Most of the discrepancies were in b-lactam/b-lactamase combinations and aminoglycosides. While reporting these groups of antibiotics with direct sensitivity test, one should be cautious. These are the major antibiotic used for life-threatening infections. In case of being heavy/lighter standard inoculums or marginal zones, repeating with standard method should be preferred to minimize the chances of error. (author)

    2011-01-01

    The built cultural heritage would face important risks in the frame of climate change. They are well identified by the major international organizations, but only in a qualitative manner, and mainly refer on the action of water or on its absence. The most active research is supported by the European Commission. The results obtained by the European project 'Noah's Ark' are the most important at the day. Dose-Response Functions with predictive climate models are used to produce vulnerability maps at a European scale of which one example is presented. The recommendations of the Council of Europe for policy makers and researchers are developed as a conclusion. Three case studies are synthesized in annex of this article: Venice, London and Paris.

  16. The changing psychology of culture from 1800 through 2000.

    Greenfield, Patricia M

    2013-09-01

    The Google Books Ngram Viewer allows researchers to quantify culture across centuries by searching millions of books. This tool was used to test theory-based predictions about implications of an urbanizing population for the psychology of culture. Adaptation to rural environments prioritizes social obligation and duty, giving to other people, social belonging, religion in everyday life, authority relations, and physical activity. Adaptation to urban environments requires more individualistic and materialistic values; such adaptation prioritizes choice, personal possessions, and child-centered socialization in order to foster the development of psychological mindedness and the unique self. The Google Ngram Viewer generated relative frequencies of words indexing these values from the years 1800 to 2000 in American English books. As urban populations increased and rural populations declined, word frequencies moved in the predicted directions. Books published in the United Kingdom replicated this pattern. The analysis established long-term relationships between ecological change and cultural change, as predicted by the theory of social change and human development (Greenfield, 2009).

  18. 'Good culture, bad culture': polygyny, cultural change and structural drivers of HIV in Papua New Guinea.

    Shih, Patti; Worth, Heather; Travaglia, Joanne; Kelly-Hanku, Angela

    2017-09-01

    Culture is often problematised as a key structural driver of HIV transmission in Papua New Guinea. Official HIV programmes, as well as church teachings, tend to focus on customary marital practices of polygyny and bride price payments as 'harmful traditions'. This focus can oversimplify the effects of current and historical nuances of cultural, political and economic change on sexual concurrency and gender inequality. Community-based healthcare workers in Southern Highlands Province explain that customary marital practices are now highly reconfigured from their traditional forms. A recent mining boom has financially advantaged local and travelling men, who are driving an increase of sexual concurrency, transactional sex and inflation of bride price payments. Healthcare workers suggest that the erosion of important social relationships and kinship obligations by the expanding cash economy has caused an intensification of individual male power while enhancing the vulnerability of women. Yet without the means to challenge the effects of uneven economic development, healthcare workers are left to target 'culture' as the central influence on individual behaviours. A commitment to address structural inequality by political leadership and in HIV prevention programmes and a careful contextualisation of cultural change is needed.

  20. Game-Changing Innovations: How Culture Can Change the Parameters of Its Own Evolution and Induce Abrupt Cultural Shifts

    2016-01-01

    One of the most puzzling features of the prehistoric record of hominid stone tools is its apparent punctuation: it consists of abrupt bursts of dramatic change that separate long periods of largely unchanging technology. Within each such period, small punctuated cultural modifications take place. Punctuation on multiple timescales and magnitudes is also found in cultural trajectories from historical times. To explain these sharp cultural bursts, researchers invoke such external factors as sudden environmental change, rapid cognitive or morphological change in the hominids that created the tools, or replacement of one species or population by another. Here we propose a dynamic model of cultural evolution that accommodates empirical observations: without invoking external factors, it gives rise to a pattern of rare, dramatic cultural bursts, interspersed by more frequent, smaller, punctuated cultural modifications. Our model includes interdependent innovation processes that occur at different rates. It also incorporates a realistic aspect of cultural evolution: cultural innovations, such as those that increase food availability or that affect cultural transmission, can change the parameters that affect cultural evolution, thereby altering the population’s cultural dynamics and steady state. This steady state can be regarded as a cultural carrying capacity. These parameter-changing cultural innovations occur very rarely, but whenever one occurs, it triggers a dramatic shift towards a new cultural steady state. The smaller and more frequent punctuated cultural changes, on the other hand, are brought about by innovations that spur the invention of further, related, technology, and which occur regardless of whether the population is near its cultural steady state. Our model suggests that common interpretations of cultural shifts as evidence of biological change, for example the appearance of behaviorally modern humans, may be unwarranted. PMID:28036346

  1. Faith in the 'cultural fix': limits to a planned cultural change program in a rural health service.

    Mahony, K

    2000-01-01

    This paper, by way of a narrative on the author's participation, explains the limits to a planned cultural change program in a large rural health service. Cultural change was identified by the CEO as crucial to the success of a major restructuring of the service, and the attitudes and beliefs of the 'old guard' were considered to be constraining progress. Advocates of cultural integration contend that shared core values across an organisation can overcome such obstacles. This is a matter of faith. An application of Habermasian theory suggests that organisational leaders are drawing on traditional/religious beliefs and practices to bolster their visions and missions at a time of motivational crisis. Though a need for cultural change in some sectors of the health services is acknowledged, the particular challenges in attempting to manipulate the traditionally embedded culture and sub-cultures of the health services is highlighted. An analysis of some of the ideas and beliefs surrounding authority, deference and discipline is undertaken. It is argued that the ritualistic reinforcement of these beliefs and the reproduction of sub-cultures along material and ideal interests militate against the implementation of objectives delineated by the CEO. While cultural analysis has revealed the irrational face of organisations and can bring to conscious awareness the taken-for-granted beliefs which inform behaviour, the cultural integrationists have a further agenda. They aim to manipulate organisational culture to subtly control employees' beliefs and hence behaviour. Cultural control is a covert form of top down authority that can be just as directive and centralizing as bureaucratic control. The author also maintains that cultural change programs alone cannot fix a problem that arose in the macro-economic sphere: a chronic lack of resources ever since the state responded to the economic crisis by cutting funds to health and welfare services.

  3. Gender, culture and changing attitudes: experiences of HIV in Zimbabwe.

    O'Brien, Stephen; Broom, Alex

    2013-01-01

    This paper draws on a series of qualitative interviews with 60 people living in economically poor communities of Harare, the capital of Zimbabwe, to provide new insight into the cultural landscape of HIV. While there has been extensive exploration of gender, sexuality, culture and HIV in Zimbabwe, there is a need to revisit these issues given the country's recent political and economic history. These questions have shaped the meanings that have been created around HIV (i.e., notions of HIV-as-death and as being produced by promiscuity) and the gendered mediation of cultural practices (i.e., forms of sexual expression and treatment uptake). Drawing on the accounts from a group directly affected by HIV, we illustrate the persistence of gendered and spiritualised ideas about 'blame', 'transmission' and 'treatment' and the disproportionate burden that still falls on Zimbabwean women. We conclude with an exploration of how everyday understandings of HIV may be shifting and the ways in which marginality, discrimination and stigma may be being challenged by openness, dialogue and attitude change.

  4. New Directions in the History of Written Culture

    Lyons, Martyn

    2012-12-01

    Full Text Available This article reviews some new directions in the history of writing practices, concentrating on Western Europe and the Americas in the nineteenth and early twentieth centuries. I identify some major intellectual influences on the field, deriving from historiography, anthropology and literary studies. I indicate some important archives specialising in popular writings which sustain the study of the writings of ordinary and semi-literate people. A few selected topics in which the history of writing practices makes a contribution are then briefly reviewed. These are, firstly, the history of correspondence and letter-writing instruction manuals, which introduces two important concepts: the ‘epistolary pact’ and ‘epistolary literacy’. Secondly, I introduce three new works on the development of postal services, stressing their role in forging national cohesion. Thirdly, I indicate how the study of emigrants’ writings has contributed to a shift of focus in the study of emigration in general. I conclude that the history of scribal culture can make a significant contribution to socio-cultural history, provided that writing is analysed in its material form, and as a text, not simply as a source of information. Writing practices deserve serious study as a social and cultural phenomenon in their own right.

  5. Descriptor revision belief change through direct choice

    Hansson, Sven Ove

    2017-01-01

    This book provides a critical examination of how the choice of what to believe is represented in the standard model of belief change. In particular the use of possible worlds and infinite remainders as objects of choice is critically examined. Descriptors are introduced as a versatile tool for expressing the success conditions of belief change, addressing both local and global descriptor revision. The book presents dynamic descriptors such as Ramsey descriptors that convey how an agent’s beliefs tend to be changed in response to different inputs. It also explores sentential revision and demonstrates how local and global operations of revision by a sentence can be derived as a special case of descriptor revision. Lastly, the book examines revocation, a generalization of contraction in which a specified sentence is removed in a process that may possibly also involve the addition of some new information to the belief set.

  11. Future directions of multiple behavior change research.

    Geller, Karly; Lippke, Sonia; Nigg, Claudio R

    2017-02-01

    Non-communicable diseases (i.e., chronic diseases including cardiovascular disease, cancer, chronic respiratory disease, diabetes and obesity) result in 36 million deaths each year. Individuals' habitual participation in a single health-risk behaviors substantially contribute to morbidity and mortality (e.g., tobacco use, daily fast food intake, etc.); however, more concerning is the impact of typically co-occurring or clustering of multiple health-risk behaviors. This burden can be minimized through successful cessation of health-risk behaviors and adoption of healthy behaviors; namely healthy lifestyle adoption or multiple health behavior change (MHBC). MHBC is a developing field and future research recommendations are provided to advance MHBC research. A valid measure of MHBC (i.e., lifestyle) is warranted to provide the needed basis for MHBC investigations and evaluations. MHBC is thought to occur through shared co-variation of underlying motivating mechanisms, but how these relationships influence behavior remains unclear. A better understanding of the relationship between behaviors and the related motivating mechanisms (and potential cross-relationship of influences) is needed. Future research should also aim to improve lifestyles through understanding how to change multiple health behaviors. Finally, MHBC research should target the development of sustainable interventions which result in lasting effects (e.g., capacity, systems, policy and environmental changes), with dissemination considered during development. Focusing MHBC research in these areas will increase our understanding and maximize the impact on the health of populations.

  12. Research on culture-bound syndromes: new directions.

    Guarnaccia, P J; Rogler, L H

    1999-09-01

    The unprecedented inclusion of culture-bound syndromes in DSM-IV provides the opportunity for highlighting the need to study such syndromes and the occasion for developing a research agenda to study them. The growing ethnic and cultural diversity of the U.S. population presents a challenge to the mental health field to develop truly cross-cultural approaches to mental health research and services. In this article, the authors provide a critique of previous analyses of the relationship between culture-bound syndromes and psychiatric diagnoses. They highlight the problems in previous classificatory exercises, which tend to focus on subsuming the culture-bound syndromes into psychiatric categories and fail to fully investigate these syndromes on their own terms. A detailed research program based on four key questions is presented both to understand culture-bound syndromes within their cultural context and to analyze the relationship between these syndromes and psychiatric disorders. Results of over a decade of research on ataques de nervios, a Latino-Caribbean cultural syndrome, are used to illustrate this research program. The four questions focus on the nature of the phenomenon, the social-cultural location of sufferers, the relationship of culture-bound syndromes to psychiatric disorders, and the social and psychiatric history of the syndrome in the life course of the sufferer.

  13. The environment and directed technical change: comment

    Hourcade, Jean-Charles; Pottier, Antonin; Espagne, Etienne

    2011-11-01

    This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield numerical results that do not support the conclusion that ambitious climate policies can be conducted 'without sacrificing (much or any) long-run growth'. Second, they select unrealistic key parameters for carbon sinks and elasticity of substitution. We find that more realistic parameters lead to very different results. Third, the model leads to an unrealistic conclusion when used to analyse endogenous growth, suggesting specification problems. (authors)

  14. Leading change in diversity and cultural competence.

    de Leon Siantz, Mary Lou

    2008-01-01

    This article describes an expanded leadership role needed in schools of nursing as the nurse of the 21st century is prepared to assume expanded roles in a diverse society. With schools of nursing becoming more global, and the diverse population of the United States rapidly growing, a critical need exists for nurses who are ready to partner in the health care that multicultural communities need locally, nationally, and globally. Diversity and cultural competence have now become central issues in nursing education, research, practice, and health policy. Diversity leadership in a school of nursing can no longer concentrate only on issues of affirmative action, recruitment, and retention. The purpose of this article is to discuss how diversity leadership must increasingly focus on building a corporate environment in schools of nursing that integrates diversity and cultural competence with the strategic plan of the School's Chief Nursing Officer, across academic programs, research, practice, and public policy to eliminate health disparities in partnership with faculty, students, staff, the University infrastructure, and the community at large. The theoretical framework that guided the strategic planning is based on the model used by the Robert Wood Johnson Executive Nurse Fellowship Program. Examples of program initiatives designed to implement the strategic plan to strengthen the diversity and cultural competence of one school of nursing environment are described.

  15. Not all cultural values are created equal: Cultural change in China reexamined through Google books.

    Zhang, Rui; Weng, Liping

    2017-06-20

    Given its major transformations in recent decades, China has figured prominently in research on cultural change. Previous research converges in showing a general trend towards individualism in contemporary China while noting that rising individualism tends to coexist with enduring collectivism. To further understand this, we tested whether perceived traditional importance of cultural values would modulate the trajectory of cultural change reflected in word usage frequencies in published books. We re-analysed Google's Chinese corpus since 1980 based on a broad sample of words associated with individualism-collectivism. We replicated the pattern of rising individualism and declining collectivism among words of modest and low perceived traditional importance. Most important, however, collectivistic words of high perceived traditional importance increased in usage frequencies with time, thus departing from the general trend towards individualism. Overall, our research underscores the role of core culture in cultural maintenance during times of rapid cultural change. © 2017 International Union of Psychological Science.

  16. Organisational culture and change: implementing person-centred care.

    Carlström, Eric D; Ekman, Inger

    2012-01-01

    The purpose of this paper is to explore the connection between organisational cultures and the employee's resistance to change at five hospital wards in Western Sweden. Staff had experienced extensive change during a research project implementing person-centred care (PCC) for patients with chronic heart failure. Surveys were sent out to 170 nurses. The survey included two instruments--the Organisational Values Questionnaire (OVQ) and the Resistance to Change Scale (RTC). The results indicate that a culture with a dominating focus on social competence decreases "routine seeking behaviour", i.e. tendencies to uphold stable routines and a reluctance to give up old habits. The results indicate that a culture of flexibility, cohesion and trust negatively covariate with the overall need for a stable and well-defined framework. An instrument that pinpoints the conditions of a particular healthcare setting can improve the results of a change project. Managers can use instruments such as the ones used in this study to investigate and plan for change processes. Earlier studies of organisational culture and its impact on the performance of healthcare organisations have often investigated culture at the highest level of the organisation. In this study, the culture of the production units--i.e. the health workers in different hospital wards--was described. Hospital wards develop their own culture and the cultures of different wards are mirrored in the hospital.

  17. DESCRIPTIVE ANALYSIS OF CORPORATE CULTURE FOLLOWING THE CHANGES

    Elenko Zahariev

    2016-09-01

    Full Text Available Corporate culture more sensibly makes additions to the economic knowledge, accompanies the strategy and tactics in management. It feels in manners and overall activity of the organization - it is empathy and tolerance, respect and responsibility. The new corporate culture transforms each participant, changes his/her mind in the general collaborations and working habits. The new corporate culture requires improving the management style. It is no longer necessary the leader only to rule, to administer and control, but to lead and inspire. The leader sets challenging targets, optimizes the performance of the teams, fuels an optimistic mood and faith, gains agreement between workers, monitors and evaluate the work in a fair way. Current study raises the problem of interpreting cultural profiles in modern organizations and analyzes corporate culture after the changes during the transition period in Bulgaria. The descriptive analysis of corporate culture allows the relatively precise identification of its various types based on the accepted classification signs.

  18. Current and future directions in culture and happiness research.

    Oishi, Shigehiro; Gilbert, Elizabeth A

    2016-04-01

    Once believed to be universal, a growing body of research shows that both the conception and predictors of happiness vary cross-culturally. First, the meaning and importance of happiness varies both across time and between nations. Americans, for instance, tend to define happiness in terms of pleasure or enjoyment and view happiness as universally positive, whereas East Asian and Middle Eastern cultures may highlight the transient and socially disruptive nature of happiness and be ambivalent about whether it is good. Second, predictors of happiness vary between cultures. Recent work highlights new mediators (e.g., relational mobility), individual predictors (e.g., person-culture fit), societal factors (e.g., good governance and wealth), within-culture variations (e.g., at the state or city level), and interventions (e.g., practicing gratitude) that differ cross-culturally or help explain cultural differences in happiness. Though many questions remain, this review highlights how these recent advances broaden and revise our understanding of culture and happiness. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2001-04-27

    Modern complex societies exhibit marked resilience to interannual-to- decadal droughts, but cultural responses to multidecadal-to-multicentury droughts can only be addressed by integrating detailed archaeological and paleoclimatic records. Four case studies drawn from New and Old World civilizations document societal responses to prolonged drought, including population dislocations, urban abandonment, and state collapse. Further study of past cultural adaptations to persistent climate change may provide valuable perspective on possible responses of modern societies to future climate change.

    The relative change of the beam pointing direction for a misaligned Porro prism resonator has been analyzed, using an oscillation axis concept for the Porro prism resonator to find the beam direction. Expressions for the beam tilting angles are presented which show that the angular misalignment in the horizontal direction will result in beam tilting in both the horizontal and vertical directions. Good agreement between experimental and theoretical results is found.

    Culture of a society reflects its social values. So, through Chinese experience, we want to show that institutional change is not only an economic or a political process but fundamentally a cultural one. It is therefore based on a change in values and mentalities. Like in a chemical reaction, we discern initial conditions, factors which triggered the reaction, catalysts and elements of synthesis. Chinese institutional change per se derived from a cultural shock induced by the Chinese economic...

  10. Tissue Engineered Skeletal Myofibers can Directly "Sense" Gravitational Force Changes

    Vandenburgh, Herman H.; Shansky, J.; DelTatto, M.; Lee, Peter; Meir, J.

    1999-01-01

    Long-term manned space flight requires a better understanding of skeletal muscle atrophy resulting from microgravity. Atrophy most likely results from changes at both the systemic level (e.g. decreased circulating growth hormone, increased circulating glucocorticoids) and locally (e.g. decreased myofiber resting tension). Differentiated skeletal myofibers in tissue culture have provided a model system over the last decade for gaining a better understanding of the interactions of exogenous growth factors, endogenous growth factors, and muscle fiber tension in regulating protein turnover rates and muscle cell growth. Tissue engineering these cells into three dimensional bioartificial muscle (BAM) constructs has allowed us to extend their use to Space flight studies for the potential future development of countermeasures. Embryonic avian muscle cells were isolated and BAMs tissue engineered as described previously. The myoblasts proliferate and fuse into aligned postmitotic myofibers after ten to fourteen days in vitro. A cylindrical muscle-like structure containing several thousand myofibers is formed which is approximately 30 mm in length, 2-3 mm in diameter, and attached at each end. For the Space Shuttle experiments, the BAMs were transferred to 55 mL bioreactor cartridges (6 BAMs/cartridge). At Kennedy Space Center, the cartridges were mounted in two Space Tissue Loss (STL) Modules (three to four cartridges per Module) and either maintained as ground controls or loaded in a Mid-Deck locker of the Space Shuttle. The BAM cartridges were continuously perfused during the experiment at 1.5 mL/ min with tissue culture medium. Eighteen BAMs were flown for nine days on Mission STS66 while eighteen BAMs served as ground controls. The complete experiment was repeated on Mission STS77 with twenty four BAMs in each group. BAMs could be maintained in a healthy state for at least 30 days in the perfusion bioreactor cartridges. The BAM muscle fibers directly detected both the

  11. Impact of cell culture process changes on endogenous retrovirus expression.

    Brorson, Kurt; De Wit, Christina; Hamilton, Elizabeth; Mustafa, Mehnaz; Swann, Patrick G; Kiss, Robert; Taticek, Ron; Polastri, Gian; Stein, Kathryn E; Xu, Yuan

    2002-11-05

    Cell culture process changes (e.g., changes in scale, medium formulation, operational conditions) and cell line changes are common during the development life cycle of a therapeutic protein. To ensure that the impact of such process changes on product quality and safety is minimal, it is standard practice to compare critical product quality and safety attributes before and after the changes. One potential concern introduced by cell culture process improvements is the possibility of increased endogenous retrovirus expression to a level above the clearance capability of the subsequent purification process. To address this, retrovirus expression was measured in scaled down and full production scaled Chinese hamster ovary (CHO) cell cultures of four monoclonal antibodies and one recombinant protein before and after process changes. Two highly sensitive, quantitative (Q)-PCR-based assays were used to measure endogenous retroviruses. It is shown that cell culture process changes that primarily alter media components, nutrient feed volume, seed density, cell bank source (i.e., master cell bank vs. working cell bank), and vial size, or culture scale, singly or in combination, do not impact the rate of retrovirus expression to an extent greater than the variability of the Q-PCR assays (0.2-0.5 log(10)). Cell culture changes that significantly alter the metabolic state of the cells and/or rates of protein expression (e.g., pH and temperature shifts, NaButyrate addition) measurably impact the rate of retrovirus synthesis (up to 2 log(10)). The greatest degree of variation in endogenous retrovirus expression was observed between individual cell lines (up to 3 log(10)). These data support the practice of measuring endogenous retrovirus output for each new cell line introduced into manufacturing or after process changes that significantly increase product-specific productivity or alter the metabolic state, but suggest that reassessment of retrovirus expression after other

  12. Advance directives: the clinical nurse specialist as a change agent.

    Meehan, Karen Anne

    2009-01-01

    The purpose of this article is to describe the impact the clinical nurse specialist (CNS) has on the advance directive process within the cardiac surgery patient population. As a change agent, the CNS needs to be able to increase the number of advance directives obtained and increase the provision of dignified, self-directed, quality patient care. With requirements from The Joint Commission and the Patient Self-determination Act, the change in process must take place to ensure that healthcare professionals are doing all they can do to carry out a patient's wishes. The 6-Source Influencer Model is applied to a case study to illustrate the role of the CNS as a change agent. Following this model, the CNS can facilitate lasting institutional change in the advance directive process. Based on the example, it is possible that a CNS can act as a change agent for other patient populations within the healthcare setting.

    2011-07-01

    Full Text Available This article puts forward a feminist analysis of the dynamics of cultural change in indigenous contexts. We intend to document the processes of cultural change that are concomitant to overcoming exclusion or marginalization of women, and to analyze the factors that cause such transformations. In this study we look for signs that can prove whether these changes are a consequence of a transformation in the gender relations — and an increase in the empowerment of women—or if they are the result of other factors and interests which have the secondary effect of reducing the marginalization of women. The specific case presented here is the participation of women in the "danza de los voladores", a recent phenomenon that suggests a cultural change in relation to gender.

  16. Organizational Culture and Scale Development: Methodological Challenges and Future Directions

    Bavik Ali

    2014-12-01

    Full Text Available Defining and measuring organizational culture (OC is of paramount importance to organizations because a strong culture could potentially increase service quality and yield sustainable competitive advantages. However, such process could be challenging to managers because the scope of OC has been defined differently across disciplines and industries, which has led to the development of various scales for measuring OC. In addition, previously developed OC scales may also not be fully applicable in the hospitality and tourism context. Therefore, by highlighting the key factors affecting the business environment and the unique characteristics of hospitality industry, this paper aims to align the scope of OC closely with the industry and to put forth the need for a new OC scale that accurately responds to the context of the hospitality industry.

    Reiman, T.; Oedewald, P.; Kettunen, J.; Rollenhagen, C.; Kahlbom, U.

    2005-04-01

    Change management has emerged as an important topic in safety-critical organisations. A lot of knowledge on change management exists, but still lot of projects fail and the safety consequences of various changes are unclear. It seems that the problems of change management are interdisciplinary, but still solutions tend to only from one perspective (e.g. technical or personnel management). There also exists empirical evidence that change has been experienced as stressful in the nuclear power plants. The cultural perspective taken in this paper strives to combine technical approaches to human resources approaches. It raises new questions that are not usually explicitly taken into account in change management. Financial pressures, change of generation and other changes in the environment have forced many organisations to reorganise their practices (e.g. downsize, outsource, and develop team-based organisations). These changes have had an impact on the culture of the organisation (and the organisational culture has mediated these changes in the first phase). (au)

  20. An assessment of cultural values and resident-centered culture change in U.S. nursing facilities.

    Banaszak-Holl, Jane; Castle, Nicholas G; Lin, Michael; Spreitzer, Gretchen

    2013-01-01

    Culture change initiatives propose to improve care by addressing the lack of managerial supports and prevalent stressful work environments in the industry; however, little is known about how culture change facilities differ from facilities in the industry that have not chosen to affiliate with the resident-centered care movements. The aim of this study was to evaluate representation of organizational culture values within a random sample of U.S. nursing home facilities using the competing values framework and to determine whether organizational values are related to membership in resident-centered culture change initiatives. We collected reports of cultural values using a well-established competing values framework instrument in a random survey of facility administrators and directors of nursing within all states. We received responses from 57% of the facilities that were mailed the survey. Directors of nursing and administrators did not differ significantly in their reports of culture and facility measures combined their responses. Nursing facilities favored market-focused cultural values on average, and developmental values, key to innovation, were the least common across all nursing homes. Approximately 17% of the facilities reported that all cultural values were strong within their facilities. Only high developmental cultural values were linked to participation in culture change initiatives. Culture change facilities were not different from non-culture change facilities in the promotion of employee focus as organizational culture, as emphasized in group culture values. Likewise, culture change facilities were also not more likely to have hierarchical or market foci than non-culture change facilities. Our results counter the argument that culture change facilities have a stronger internal employee focus than facilities more generally but do show that culture change facilities report stronger developmental cultures than non-culture change facilities, which

  5. Culture change, leadership and the grass-roots workforce.

    Edwards, Mark; Penlington, Clare; Kalidasan, Varadarajan; Kelly, Tony

    2014-08-01

    The NHS is arguably entering its most challenging era. It is being asked to do more for less and, in parallel, a cultural shift in response to its described weaknesses has been prescribed. The definition of culture, the form this change should take and the mechanism to achieve it are not well understood. The complexity of modern healthcare requires that we evolve our approach to the workforce and enhance our understanding of the styles of leadership that are required in order to bring about this cultural change. Identification of leaders within the workforce and dissemination of a purposeful and strategic quality improvement agenda, in part defined by the general workforce, are important components in establishing the change that the organisation currently requires. We are implementing this approach locally by identifying and developing grassroots networks linked to a portfolio of safety and quality projects. © 2014 Royal College of Physicians.

    Full Text Available This work aims to propose a model for the conduct of cultural change in the IT department of a company in the telecommunications industry. To achieve the goal proposed exploratory, technical procedures used were the case study and literature review. The techniques of data collection in the case study were: participant observation, unstructured interview and document analysis. The proposed model consists of five steps: analysis of the company's strategic planning, cultural diagnosis of the IT department, brainstorming with the staff and managers, compared to the case studies surveyed and proposed actions for the conduct of cultural change. We conclude that a receptive environment, employees not only understand why the changes are necessary, but engage with the process and faithfully executes the steps required, favoring the strategic positioning of the company.

  7. Invasive candidiasis: future directions in non-culture based diagnosis.

    Posch, Wilfried; Heimdörfer, David; Wilflingseder, Doris; Lass-Flörl, Cornelia

    2017-09-01

    Delayed initial antifungal therapy is associated with high mortality rates caused by invasive candida infections, since accurate detection of the opportunistic pathogenic yeast and its identification display a diagnostic challenge. diagnosis of candida infections relies on time-consuming methods such as blood cultures, serologic and histopathologic examination. to allow for fast detection and characterization of invasive candidiasis, there is a need to improve diagnostic tools. trends in diagnostics switch to non-culture-based methods, which allow specified diagnosis within significantly shorter periods of time in order to provide early and appropriate antifungal treatment. Areas covered: within this review comprise novel pathogen- and host-related testing methods, e.g. multiplex-PCR analyses, T2 magnetic resonance, fungus-specific DNA microarrays, microRNA characterization or analyses of IL-17 as biomarker for early detection of invasive candidiasis. Expert commentary: Early recognition and diagnosis of fungal infections is a key issue for improved patient management. As shown in this review, a broad range of novel molecular based tests for the detection and identification of Candida species is available. However, several assays are in-house assays and lack standardization, clinical validation as well as data on sensitivity and specificity. This underscores the need for the development of faster and more accurate diagnostic tests.

  8. Relationship between staff-reported culture change and occupancy rate and organizational commitment among nursing homes in South Korea.

    Lee, Minhong; Choi, Jae-Sung; Lim, Jinseop; Kim, Young Sun

    2013-04-01

    This study aims to examine culture change in nursing homes in South Korea and to identify the outcomes of culture change implementation. Data were taken from survey responses from 223 top- or mid-level staff among nursing homes in South Korea that were selected through a proportionate random-stratified sampling method from four regions nationwide. Culture change in nursing homes was operationalized by five person-directed care (PDC) constructs and three organizational environment constructs, and outcome quality was indicated by changes to occupancy rate and organizational commitment. After controlling for facility characteristics, the effect of staff-reported culture change on occupancy rate and organizational commitment was analyzed through the multiple-regression method. Consistent with previous research, this study revealed positive effects of culture change for nursing homes in South Korea. The study found that staff-reported culture change correlated with occupancy rate and organizational commitment. Given that culture change variables were significantly related to occupancy rate and organizational commitment, the findings of the study provide a persuasive argument that policies and/or programs to support culture change in nursing homes should be enhanced. Management-level workers in these facilities should have the skills and knowledge to foster more PDC and a more person-directed environment.

  9. The culture of excellence. Challenges and opportunities during changing times

    Suciu Marta-Christina

    2017-07-01

    Full Text Available The main goal of the paper is to highlight the importance of supporting the promotion of the culture of excellence among people involved in a way or another in contemporary business. In order to support business excellence, the culture of excellence have to empower and engage all the people within an organization to think out of the box in a modern vision suitable to the challenging and changing times we are facing now. All over the world, in the most competitive countries, regions and sectors of activities there is a paradigmatic change of business strategies and policies oriented more and more towards performance and excellence. The paper highlights the importance of promoting the culture of excellence in the contemporary changing business environment. It suggests an important shift from a perspective that focuses on the so called ‘hero of excellence’ towards promoting the culture of excellence among the whole organization. Within modern business, in order to face challenges of the changing times and to explore their opportunities all the people from an organization are considered to manifest as ‘heroes of excellence’ by co-creating and co-working together within creative and innovative teams. They have to contribute and to participate actively to assure, preserve and develop the competitiveness and well being of the whole organization. The paper supports a holistic, cross disciplinary and integrated vision. It is structured into three parts including: a brief literature review based on an overview of the current state of the literature dedicated to the topic of culture of excellence (part 1; presentation of the main steps of the process of building a sustainable high performance organization (part 2; a brief presentation of examples of best practice and case studied identified internationally (part 3; conclusions that highlight the importance of culture of excellence in changing and challenging times.

  10. Up or down? Reading direction influences vertical counting direction in the horizontal plane - a cross-cultural comparison.

    Göbel, Silke M

    2015-01-01

    Most adults and children in cultures where reading text progresses from left to right also count objects from the left to the right side of space. The reverse is found in cultures with a right-to-left reading direction. The current set of experiments investigated whether vertical counting in the horizontal plane is also influenced by reading direction. Participants were either from a left-to-right reading culture (UK) or from a mixed (left-to-right and top-to-bottom) reading culture (Hong Kong). In Experiment 1, native English-speaking children and adults and native Cantonese-speaking children and adults performed three object counting tasks. Objects were presented flat on a table in a horizontal, vertical, and square display. Independent of culture, the horizontal array was mostly counted from left to right. While the majority of English-speaking children counted the vertical display from bottom to top, the majority of the Cantonese-speaking children as well as both Cantonese- and English-speaking adults counted the vertical display from top to bottom. This pattern was replicated in the counting pattern for squares: all groups except the English-speaking children started counting with the top left coin. In Experiment 2, Cantonese-speaking adults counted a square array of objects after they read a text presented to them either in left-to-right or in top-to-bottom reading direction. Most Cantonese-speaking adults started counting the array by moving horizontally from left to right. However, significantly more Cantonese-speaking adults started counting with a top-to-bottom movement after reading the text presented in a top-to-bottom reading direction than in a left-to-right reading direction. Our results show clearly that vertical counting in the horizontal plane is influenced by longstanding as well as more recent experience of reading direction.

  11. Mergers and acquisitions: some implications of cultural change.

    Cavanaugh, S J

    1996-01-01

    A result of recent National Health Service reforms is the need to investigate, and possibly change, the culture of the professional working relationship between members of staff and their employer. This is particularly the case in situations of mergers and acquisitions where staff working from different cultural environments must work together. Mergers are becoming a feature of health service provision, perhaps this becomes most obvious with the recent moves by colleges of nursing and midwifery into the higher education sector and amalgamations of some purchasing authorities. Mergers highlight the practical issues of bringing together different organizational and work cultures to deliver a high quality service. This article discusses some aspects of the nature of organizational culture, the human impact of mergers and acquisitions and offers strategies for managing these events.

  12. Population size does not explain past changes in cultural complexity.

    Vaesen, Krist; Collard, Mark; Cosgrove, Richard; Roebroeks, Wil

    2016-04-19

    Demography is increasingly being invoked to account for features of the archaeological record, such as the technological conservatism of the Lower and Middle Pleistocene, the Middle to Upper Paleolithic transition, and cultural loss in Holocene Tasmania. Such explanations are commonly justified in relation to population dynamic models developed by Henrich [Henrich J (2004)Am Antiq69:197-214] and Powell et al. [Powell A, et al. (2009)Science324(5932):1298-1301], which appear to demonstrate that population size is the crucial determinant of cultural complexity. Here, we show that these models fail in two important respects. First, they only support a relationship between demography and culture in implausible conditions. Second, their predictions conflict with the available archaeological and ethnographic evidence. We conclude that new theoretical and empirical research is required to identify the factors that drove the changes in cultural complexity that are documented by the archaeological record.

    The molecular mechanisms of prion-induced cytotoxicity remain largely obscure. Currently, only a few cell culture models have exhibited the cytopathic changes associated with prion infection. In this study, we introduced a cell culture model based on differentiated neurosphere cultures isolated from the brains of neonatal prion protein (PrP)-null mice and transgenic mice expressing murine PrP (dNP0 and dNP20 cultures). Upon exposure to mouse Chandler prions, dNP20 cultures supported the de novo formation of abnormal PrP and the resulting infectivity, as assessed by bioassays. Furthermore, this culture was susceptible to various prion strains, including mouse-adapted scrapie, bovine spongiform encephalopathy, and Gerstmann-Sträussler-Scheinker syndrome prions. Importantly, a subset of the cells in the infected culture that was mainly composed of astrocyte lineage cells consistently displayed late-occurring, progressive signs of cytotoxicity as evidenced by morphological alterations, decreased cell viability, and increased lactate dehydrogenase release. These signs of cytotoxicity were not observed in infected dNP0 cultures, suggesting the requirement of endogenous PrP expression for prion-induced cytotoxicity. Degenerated cells positive for glial fibrillary acidic protein accumulated abnormal PrP and exhibited features of apoptotic death as assessed by active caspase-3 and terminal deoxynucleotidyltransferase nick-end staining. Furthermore, caspase inhibition provided partial protection from prion-mediated cell death. These results suggest that differentiated neurosphere cultures can provide an in vitro bioassay for mouse prions and permit the study of the molecular basis for prion-induced cytotoxicity at the cellular level.

  15. An evolutionary framework for cultural change: Selectionism versus communal exchange

    Gabora, Liane

    2013-06-01

    Dawkins' replicator-based conception of evolution has led to widespread mis-application of selectionism across the social sciences because it does not address the paradox that necessitated the theory of natural selection in the first place: how do organisms accumulate change when traits acquired over their lifetime are obliterated? This is addressed by von Neumann's concept of a self-replicating automaton (SRA). A SRA consists of a self-assembly code that is used in two distinct ways: (1) actively deciphered during development to construct a self-similar replicant, and (2) passively copied to the replicant to ensure that it can reproduce. Information that is acquired over a lifetime is not transmitted to offspring, whereas information that is inherited during copying is transmitted. In cultural evolution there is no mechanism for discarding acquired change. Acquired change can accumulate orders of magnitude faster than, and quickly overwhelm, inherited change due to differential replication of variants in response to selection. This prohibits a selectionist but not an evolutionary framework for culture and the creative processes that fuel it. The importance non-Darwinian processes in biological evolution is increasingly recognized. Recent work on the origin of life suggests that early life evolved through a non-Darwinian process referred to as communal exchange that does not involve a self-assembly code, and that natural selection emerged from this more haphazard, ancestral evolutionary process. It is proposed that communal exchange provides an evolutionary framework for culture that enables specification of cognitive features necessary for a (real or artificial) societies to evolve culture. This is supported by a computational model of cultural evolution and a conceptual network based program for documenting material cultural history, and it is consistent with high levels of human cooperation.

  16. Managing strategic change--strategy, culture and action.

    Johnson, G

    1992-02-01

    One of the major problems facing senior executives is that of effecting significant strategic change in their organizations. This paper develops a number of explanatory frameworks which address the links between the development of strategy in organizations, dimensions of corporate culture and managerial action. In considering such linkages, and by illustrating them with examples from work undertaken in companies, the paper also seeks to advance our understanding of the problems and means of managing strategic change.

  2. A non-equilibrium neutral model for analysing cultural change.

    Kandler, Anne; Shennan, Stephen

    2013-08-07

    Neutral evolution is a frequently used model to analyse changes in frequencies of cultural variants over time. Variants are chosen to be copied according to their relative frequency and new variants are introduced by a process of random mutation. Here we present a non-equilibrium neutral model which accounts for temporally varying population sizes and mutation rates and makes it possible to analyse the cultural system under consideration at any point in time. This framework gives an indication whether observed changes in the frequency distributions of a set of cultural variants between two time points are consistent with the random copying hypothesis. We find that the likelihood of the existence of the observed assemblage at the end of the considered time period (expressed by the probability of the observed number of cultural variants present in the population during the whole period under neutral evolution) is a powerful indicator of departures from neutrality. Further, we study the effects of frequency-dependent selection on the evolutionary trajectories and present a case study of change in the decoration of pottery in early Neolithic Central Europe. Based on the framework developed we show that neutral evolution is not an adequate description of the observed changes in frequency. Copyright © 2013 Elsevier Ltd. All rights reserved.

  8. Carbon leakage revisited. Unilateral climate policy under directed technical change

    Maria, Corrado Di; Van derWerf, E.

    2005-01-01

    This paper analyzes the consequences of unilateral climate policy in the presence of directed technical change. We develop a dynamic two-country model in which two otherwise identical countries differ in their environmental policy: one of the countries enforces a (binding) cap on emissions while the other does not. Focusing on carbon leakage, we show how, compared with a 'traditional' endogenous growth model, directed technical change will always lead to lower emissions in the unconstrained country. When clean and dirty goods are good substitutes, it may even be induced to reduce its emissions below the optimum level when both countries are unconstrained, so leakage is negative

  9. An ethnographic study of nursing home culture to define organizational realities of culture change.

    Deutschman, Marian T

    2005-01-01

    The current system of delivery of nursing home care is costly both in dollars and in human terms. Culture change may provide solutions to both issues. Culture change has a different meaning for different organizations depending on where they are in the continuum of change. Detailed observation of staff members "in action" in three long-term care facilities over a period of several months was supplemented by formal and informal interviews of organization members to gain an understanding of the culture of the nursing home organization. Four three-hour observations in each of three facilities, representing privately-held and not-for-profit organizations in urban, suburban, and rural locations yielded insights into the routine, recruitment, training, teamwork, activities, leadership, role-modeling, mentoring, staff and resident satisfaction, weekend staffing and activities, bureaucratic structure, and sharing of best practices. Discussion of each of these issues may provide a starting point for all those facilities that are contemplating significant culture change. If the objective is to have facilities truly embrace a new set of values, then the change begins with the owners and administrators of nursing homes who need to focus on building new relationships with all the stakeholders. In-depth interviews of organization members and six chief executive officers in long-term care in the Western New York area culminated the study with the development of a fifty-question survey for decision makers.

    2010-02-01

    Full Text Available As part of an overall decline in biodiversity, populations of many organisms are declining and species are being lost at unprecedented rates around the world. This includes many populations and species of amphibians. Although numerous factors are affecting amphibian populations, we show potential direct and indirect effects of climate change on amphibians at the individual, population and community level. Shifts in amphibian ranges are predicted. Changes in climate may affect survival, growth, reproduction and dispersal capabilities. Moreover, climate change can alter amphibian habitats including vegetation, soil, and hydrology. Climate change can influence food availability, predator-prey relationships and competitive interactions which can alter community structure. Climate change can also alter pathogen-host dynamics and greatly influence how diseases are manifested. Changes in climate can interact with other stressors such as UV-B radiation and contaminants. The interactions among all these factors are complex and are probably driving some amphibian population declines and extinctions.

  13. Political Culture and Covalent Bonding. A Conceptual Model of Political Culture Change

    Camelia Florela Voinea

    2015-01-01

    Full Text Available Our class of models aims at explaining the dynamics of political attitude change by means of the dynamic changes in values, beliefs, norms and knowledge with which it is associated. The model constructs a political culture perspective over the relationship between macro and micro levels of a society and polity. The model defines the bonding mechanism as a basic mechanism of the political culture change by taking inspiration from the valence bonding theory in Chemistry, which has inspired the elaboration of the mechanisms and processes underlying the political culture emergence and the political culture control over the relationship between macro-level political entities and the micro-level individual agents. The model introduces operational definitions of the individual agent in political culture terms. The simulation model is used for the study of emergent political culture change phenomena based on individual interactions (emergent or upward causation as well as the ways in which the macro entities and emergent phenomena influence in turn the behaviors of individual agents (downward causation. The model is used in the ongoing research concerning the quality of democracy and political participation of the citizens in the Eastern European societies after the Fall of Berlin Wall. It is particularly aimed at explaining the long-term effect of the communist legacy and of the communist polity concept and organization onto the political mentalities and behaviors of the citizens with respect to democratic institutions and political power. The model has major implications in political socialization, political involvement, political behavior, corruption and polity modeling.

  14. A call to improve practice concerning cultural sensitivity in advance directives: a review of the literature.

    Zager, B Sue; Yancy, Margaret

    2011-12-01

    The Patient Self Determination Act of 1990 mandates healthcare providers (HCP) to speak with patients about end-of-life preferences and advance directives (AD). HCP work with patients of varying cultures, and standard ADs do not address cultural differences. In order to understand various cultural beliefs, cultural sensitivity is important especially when discussing advance care planning (ACP). Individuals from differing ethnic backgrounds are likely to turn to their traditional norms of practice when ill or treatment choices must be made. An AD that addresses varying cultural values and beliefs was sought. A comprehensive review of the literature was conducted. Articles selected for review included qualitative and quantitative studies. The evidence was evaluated and synthesized for information related to cultural sensitivity and ADs. Three common themes emerged related to ACP discussions and culture. Healthcare provider awareness, communication, and education concerning cultural differences and ACP assisted in meeting the needs for end-of-life planning in the current era of increased globalization. Education for HCP on cultural differences and how to lead discussions promoted ACP. ADs are an essential part of health care and promote patient-centered care. (HCP) should be able to recognize differing cultural values and beliefs in order to initiate conversations about end of life. Initiating conversations about ACP can be facilitated by using open-ended questions that respect the values and beliefs of various cultures. Copyright ©2011 Sigma Theta Tau International.

    Beatriz Plaza

    2016-12-01

    Full Text Available Symbolic knowledge-driven innovations can play an important role in the economic development of cities and regions. Cultural events and infrastructures can act as powerful connectivity engines, generating new connections, rewiring links, and repositioning institutions/cities/regions on the Internet map. Within this framework, this paper aims to contribute to the analytical understanding of culture-led repositioning. For this purpose we perform regression analysis with cultural networks (observational cross-sectional network data from digital media for a specific cultural case study: the Basque Culinary Center (BCC, a higher education faculty of haute cuisine promoted by the University of Mondragon along with a group of Michelin-starred chefs. Results show that a cultural sector, such as haute cuisine, can contribute to structural changes in connectivity patterns, putting an institution/city/region on the media map. It is the connection (in the online press of the BCC to the influential Michelin-starred chefs that can fuel the accumulation of press articles (media items on the BCC; and it is precisely this accumulation of press articles that can impact BCC revenues. Put differently, the co-branding between the influential Michelin chefs and the BCC may have put the BCC on the press map, promoting new student registrations and fostering Basque haute cuisine. The main contribution of this article is a prototype of regression analysis to test repositioning with network data.

  19. Cultural and structural changes in radioactive waste management organisations

    2007-01-01

    In recent years the socio-political environment of radioactive waste management (RWM) has been changing in a significant way. Stakeholder dialogue has become a leading principle. How have RWM organisations adapted to this societal transition? How do they balance the requirement of openness and the increasing concerns over the security of facilities? Are there organisations that have successfully changed from a technical- to a customer-focused culture? What resistance was met? Which tools and instruments helped organisations evolve? This report documents the changes observed by RWM managers and sets those changes in an organisational sciences framework. All those who are intent on learning about the changes that have taken place in the field of radioactive waste management, or whose own organisations in any sector must adapt to societal demand, will be interested by the experience and insight reported here.

  2. Motion direction estimation based on active RFID with changing environment

    Jie, Wu; Minghua, Zhu; Wei, He

    2018-05-01

    The gate system is used to estimate the direction of RFID tags carriers when they are going through the gate. Normally, it is difficult to achieve and keep a high accuracy in estimating motion direction of RFID tags because the received signal strength of tag changes sharply according to the changing electromagnetic environment. In this paper, a method of motion direction estimation for RFID tags is presented. To improve estimation accuracy, the machine leaning algorithm is used to get the fitting function of the received data by readers which are deployed inside and outside gate respectively. Then the fitted data are sampled to get the standard vector. We compare the stand vector with template vectors to get the motion direction estimation result. Then the corresponding template vector is updated according to the surrounding environment. We conducted the simulation and implement of the proposed method and the result shows that the proposed method in this work can improve and keep a high accuracy under the condition of the constantly changing environment.

    2014-07-01

    Several archaeological studies in the Central Andes have pointed at the temporal coincidence of climatic fluctuations (both long- and short-term) and episodes of cultural transition and changes of socioeconomic structures throughout the pre-Columbian period. Although most scholars explain the connection between environmental and cultural changes by the impact of climatic alterations on the capacities of the ecosystems inhabited by pre-Columbian cultures, direct evidence for assumed demographic consequences is missing so far. In this study, we address directly the impact of climatic changes on the spatial population dynamics of the Central Andes. We use a large dataset of pre-Columbian mitochondrial DNA sequences from the northern Rio Grande de Nasca drainage (RGND) in southern Peru, dating from ∼840 BC to 1450 AD. Alternative demographic scenarios are tested using Bayesian serial coalescent simulations in an approximate Bayesian computational framework. Our results indicate migrations from the lower coastal valleys of southern Peru into the Andean highlands coincident with increasing climate variability at the end of the Nasca culture at ∼640 AD. We also find support for a back-migration from the highlands to the coast coincident with droughts in the southeastern Andean highlands and improvement of climatic conditions on the coast after the decline of the Wari and Tiwanaku empires (∼1200 AD), leading to a genetic homogenization in the RGND and probably southern Peru as a whole.

  5. The Effect of Translations on Cultural Change from The Ottomans to The Turkish Republic

    Fatih ŞİMŞEK

    2017-12-01

    Full Text Available The innovation movement in the Ottoman Empire, which lasted more than a hundred years, involved an intense translation activity in nearly every field. These translation activities eventually led to the creation of cultural, literary and political works in the Western model. The ideas and thoughts which changed the Ottoman Empire into a democratic republic arose from these westernization movements. During the early years of the Turkish Republic, culture, literature, politics and law were all guided by translations from the Western world. This paper seeks to examine how government-led innovation movements took place in fields such as the military, law, literature and culture during the transition period between the Ottoman Empire and the Turkish Republic, and describe the translation methods which were at the centre of these movements. It will discuss how these translation-oriented innovations shaped the target society in the defined period, the way the target culture was directed and how the government-led cultural change, which did not take into account the cultural norms of the target society and traditions, affected the society.

    The extent to which an organization's culture exhibits support for its employees' efforts to balance work and personal responsibilities has been shown to influence a number of work- and home-related outcomes. This study tests a model with a mix of mediated and moderated relationships to investigate direct and indirect routes by which work-home culture may affect employee well-being. Sex differences in these relationships are also explored. Data collected from public sector employees in the UK...

    To evaluate the effectiveness of direct identification of pathogens of bacteremia by direct matrix assisted laser desorption ionization time-flight mass spectrometry (mALDI-TOF) compared to routine method. A prospective study included 211 positive blood cultures obtained from 116 patients (106 adults and 10 children, aged from 2 weeks to 77 years old in the ICU after open heart surgery. Incubation was carried out under aerobic vials with a sorbent for antibiotics Analyzer BacT/ALERT 3D 120 (bioMerieux, France) in parallel with the primary sieving blood cultures on solid nutrient media with subsequent identification of pure cultures using MALDI-TOF mass spectrometry analyzer Vitek MS, bioMerieux, France routine method), after appropriate sample preparation we carried out a direct (without screening) MALDI-TOF mass spectrometric study of monocomponental blood cultures (n = 201). using a routine method in 211 positive blood cultures we identified 23 types of microorganisms (Staphylococcus (n = 87), Enterobacteria- ceae (n = 71), Enterococci (n = 20), non-fermentative Gram-negative bacteria (n = 18), others (n = 5). The average time of incubation of samples to obtain a signal of a blood culture growth was 16.2 ± 7.4 h (from 3.75 to 51 hours.) During the first 12 hours of incubation, growth was obtained in 32.4% of the samples, and on the first day in 92.2%. In the direct mass spectrometric analysis mnonocomponental blood cultures (n = 201) is well defined up to 153 species of the sample (76.1%), while the share of successful identification of Gram-negative bacteria was higher than that of Gram-positive (85.4 and 69, 1%, respectively p = 0.01). The high degree of consistency in the results of standard and direct method of identifying blood cultures using MALDI-TOF mass spectrometry (κ = 0.96, p direct mass spectrometric analysis, including sample preparation, was no longer than 1 hour: The method of direct MALDI-TOF mass spectrometry allows to significantly speed up

  8. Interventions for confusion and dementia. 5: Changing cultures.

    Woodrow, P

    Previous articles in this series (Vol 7(15): 891-94; Vol 7(17): 1018-20; Vol 7(19): 1145-49; Vol 7(20): 1247-50) have explored the promotion of quality of life for people with dementia and how this can be achieved through existing interventions. This final article moves from discussing specific interventions to cover wider issues around healthcare beliefs and values. A brief historical overview of dementia care is given, outlining the inherited structures and values. Much valuable work has been carried out by the Bradford Dementia Group, who has described changes in dementia care as moving from an 'old' to a 'new' culture. This 'new culture', offering a comprehensive person-centred approach to holistic care, is explored with reference to the work of Kitwood, who has done much to promote quality of life for people suffering from dementia.

  9. Implementing culture change in long-term dementia care settings.

    McGreevy, Jessica

    2016-01-06

    The approach to nursing in long-term care settings for people living with dementia continues to evolve from a traditional, task-oriented culture to one that is person-centred. Such change can be difficult to manage and may encounter considerable opposition; having an understanding of change management and leadership styles may help to make this transition easier. This article discusses the differences between task-oriented and person-centred care, theories of management, motivation and leadership styles, and focuses on those that are most appropriate for this type of change. An improved understanding of these theories will enable nurses to support others in the delivery of person-centred care.

  11. The CARE model of social accountability: promoting cultural change.

    Meili, Ryan; Ganem-Cuenca, Alejandra; Leung, Jannie Wing-sea; Zaleschuk, Donna

    2011-09-01

    On the 10th anniversary of Health Canada and the Association of Faculties of Medicine of Canada's publication in 2001 of Social Accountability: A Vision for Canadian Medical Schools, the authors review the progress at one Canadian medical school, the College of Medicine at the University of Saskatchewan, in developing a culture of social accountability. They review the changes that have made the medical school more socially accountable and the steps taken to make those changes possible. In response to calls for socially accountable medical schools, the College of Medicine created a Social Accountability Committee to oversee the integration of these principles into the college. The committee developed the CARE model (Clinical activity, Advocacy, Research, Education and training) as a guiding tool for social accountability initiatives toward priority health concerns and as a means of evaluation. Diverse faculty and student committees have emerged as a result and have had far-reaching impacts on the college and communities: from changes in curricula and admissions to community programming and international educational experiences. Although a systematic assessment of the CARE model is needed, early evidence shows that the most significant effects can be found in the cultural shift in the college, most notably among students. The CARE model may serve as an important example for other educational institutions in the development of health practitioners and research that is responsive to the needs of their communities.

  12. Performance measurement of workplace change: in two different cultural contexts

    change in different contexts. Two organisations in Thailand and one organisation in The Netherlands were selected to serve as case studies. The impact of culture was explored as a contextual background. Research methods Based on literature review an overview of performance measurement systems and measures has been developed. The list of corporate real estate performance measures has been classified in six categories according to Bradley (2002 and subsequently compared with the findings from the case studies. The six categories include: 1 stakeholder perception, 2 financial health, 3 organisational development, 4 productivity, 5 environmental responsibility and 6 cost efficiency. The impact of workplace change was examined using the work environment diagnosis instrument (WODI questionnaire which evaluates employees’ responses to the changed work environment in three areas: employee satisfaction, perceived productivity support and prioritised aspects (Maarleveld, et al., 2009. The Organisational Culture Assessment Instrument (OCAI; Cameron and Quinn, 2006 was used to assess organisational culture. National culture was measured by using the Value Survey Module 94 (VSM94; Hofstede, 1997. Research findings The conceptual framework that came to the fore from the literature review showed to be useful for both theoretical understanding of performance measurement and practical applications. Proposed performance measures have been applied in all three case studies but in different ways. The three case studies showed that performance measurement of an organisation is multi-dimensional. It includes several performance criteria and performance measures beyond cost efficiency. All seven performance criteria mentioned by Sink and Tuttle (1989 have been applied in all three cases including effectiveness, efficiency, quality, productivity, quality of worklife, innovation and profitability.

  14. Lack of direct mitogenic activity of dichloroacetate and trichloroacetate in cultured rat hepatocytes

    Walgren, Jennie L.; Kurtz, David T.; McMillan, JoEllyn M.

    2005-01-01

    Dichloroacetate (DCA) and trichloroacetate (TCA) are hepatocarcinogenic metabolites of the common groundwater contaminant, 1,1,2-trichloroethylene. DCA and TCA have been shown to induce hepatocyte proliferation in vivo, but it is not known if this response is the result of direct mitogenic activity or whether cell replication occurs indirectly in response to tissue injury or inflammation. In this study we used primary cultures of rat hepatocytes, a species susceptible to DCA- but not TCA-induced hepatocarcinogenesis, to determine whether DCA and TCA are direct hepatocyte mitogens. Rat hepatocytes, cultured in growth factor-free medium, were treated with 0.01-1.0 mM DCA or TCA for 10-40 h; cell replication was then assessed by measuring incorporation of 3 H-thymidine into DNA and by cell counts. DCA or TCA treatment did not alter 3 H-thymidine incorporation in the cultured hepatocytes. Although an increase in cell number was not observed, DCA treatment significantly abrogated the normal background cell loss, suggesting an ability to inhibit apoptotic cell death in primary hepatocyte cultures. Furthermore, treatment with DCA synergistically enhanced the mitogenic response to epidermal growth factor. The data indicate that DCA and TCA are not direct mitogens in hepatocyte cultures, which is of interest in view of their ability to stimulate hepatocyte replication in vivo. Nevertheless, the synergistic enhancement of epidermal growth factor-induced hepatocyte replication by DCA is of particular interest and warrants further study

  15. Between Flexibility and Reliability. Changing Planning Culture in China

    Chiu-Yuan Wang

    2014-10-01

    Full Text Available The aim of this research is to provide an outline to address questions with regard to the transformation of planning in China that has occurred after the 1980s. The research is using “planning evolution” as the main research skeleton. The starting point is to investigate to what extent Chinese urban planning has developed after the opening up and other reforms under the state-led and market-driven modes of Chinese reformation, and to investigate how the different modes and various actors have influenced urban planning, based on the investigation of the respective political and economic changes within the initial reformation in general, and planning in particular. In recent years, China has undeniably undergone a dramatic process of urban growth and transformation. Apart from its speed and scope, it is less recognized that these processes are confronting the Chinese planning institutions with new and unexpected demands almost on a daily basis. In reference to the increasing importance of private investments and developments within the Chinese urbanization process, a new balance between public planning and private developments, and between top-down and bottom-up approaches is required to be able to generate both a reliable and responsible framework for long-term urban development and a flexible system of implementation that meets the needs of changing conditions and new demands. Flexibility and reliability become the new demands for planning practice. Based on the theory of planning culture, planning traditions, concepts, systems and decision-making processes are always related to the cultural context and cultural background of the people and societies involved. Investigating the contemporary urban transformation and urban development processes in China can allow us to outline the new planning culture of contemporary China in relation to its historical roots and traditional characteristics in a long term framework. I argue that the changing

  16. Phenotypic Changes Exhibited by E. coli Cultured in Space

    Luis Zea

    2017-08-01

    Full Text Available Bacteria will accompany humans in our exploration of space, making it of importance to study their adaptation to the microgravity environment. To investigate potential phenotypic changes for bacteria grown in space, Escherichia coli was cultured onboard the International Space Station with matched controls on Earth. Samples were challenged with different concentrations of gentamicin sulfate to study the role of drug concentration on the dependent variables in the space environment. Analyses included assessments of final cell count, cell size, cell envelope thickness, cell ultrastructure, and culture morphology. A 13-fold increase in final cell count was observed in space with respect to the ground controls and the space flight cells were able to grow in the presence of normally inhibitory levels of gentamicin sulfate. Contrast light microscopy and focused ion beam/scanning electron microscopy showed that, on average, cells in space were 37% of the volume of their matched controls, which may alter the rate of molecule–cell interactions in a diffusion-limited mass transport regime as is expected to occur in microgravity. TEM imagery showed an increase in cell envelope thickness of between 25 and 43% in space with respect to the Earth control group. Outer membrane vesicles were observed on the spaceflight samples, but not on the Earth cultures. While E. coli suspension cultures on Earth were homogenously distributed throughout the liquid medium, in space they tended to form a cluster, leaving the surrounding medium visibly clear of cells. This cell aggregation behavior may be associated with enhanced biofilm formation observed in other spaceflight experiments.

  17. Rethinking the globalisation of problem-based learning: how culture challenges self-directed learning.

    Frambach, Janneke M; Driessen, Erik W; Chan, Li-Chong; van der Vleuten, Cees P M

    2012-08-01

    Medical schools worldwide are increasingly switching to student-centred methods such as problem-based learning (PBL) to foster lifelong self-directed learning (SDL). The cross-cultural applicability of these methods has been questioned because of their Western origins and because education contexts and learning approaches differ across cultures. This study evaluated PBL's cross-cultural applicability by investigating how it is applied in three medical schools in regions with different cultures in, respectively, East Asia, the Middle East and Western Europe. Specifically, it investigated how students' cultural backgrounds impact on SDL in PBL and how this impact affects students. A qualitative, cross-cultural, comparative case study was conducted in three medical schools. Data were collected through 88 semi-structured, in-depth interviews with Year 1 and 3 students, tutors and key persons involved in PBL, 32 observations of Year 1 and 3 PBL tutorials, document analysis, and contextual information. The data were thematically analysed using the template analysis method. Comparisons were made among the three medical schools and between Year 1 and 3 students across and within the schools. The cultural factors of uncertainty and tradition posed a challenge to Middle Eastern students' SDL. Hierarchy posed a challenge to Asian students and achievement impacted on both sets of non-Western students. These factors were less applicable to European students, although the latter did experience some challenges. Several contextual factors inhibited or enhanced SDL across the cases. As students grew used to PBL, SDL skills increased across the cases, albeit to different degrees. Although cultural factors can pose a challenge to the application of PBL in non-Western settings, it appears that PBL can be applied in different cultural contexts. However, its globalisation does not postulate uniform processes and outcomes, and culturally sensitive alternatives might be developed.

  19. In Brief: Report details climate change effects on cultural sites

    Zielinski, Sarah

    2007-04-01

    A new report from UNESCO (United Nations Educational, Scientific, and Cultural Organization) details how 26 World Heritage sites could be affected by coming climate changes. The 26 examples, which are meant to be representative of the range of threats to the 830 sites inscribed in the World Heritage List, are divided into five types: archaeological sites, glaciers, historic cities and settlements, marine biodiversity, and terrestrial biodiversity. Some of the examples include the Great Barrier Reef, which is expected to experience more frequent episodes of coral bleaching; Timbuktu in Mali, threatened by desertification; and the Chavín Archaeological Site in the Peruvian Central Andes, one of the earliest and best-known pre-Columbian sites, which could be affected by glacier melting and flooding.

    Professional development training courses, and a unique promoting appraisal system have been combined in the form of a training matrix and are being used as a culture change agent. This training and system modification is currently being implemented within the Nuclear Materials Processing Division of the Savannah River Site. It is designed to help solve the systems problems of managers and supervisors while enabling subordinates to develop themselves professionally, and starts with a promoting appraisal between a manager and a subordinate. These easy to apply appraisals are becoming an integral part of the business system, and result in giving a manager greater control over business change and greater influence over the work each employee accomplishes

  1. Taking action on overuse: Creating the culture for change.

    2017-12-01

    Unnecessary care contributes to high costs and places patients at risk of harm. While most providers support reducing low-value care, changing established practice patterns is difficult and requires active engagement in sustained behavioral, organizational, and cultural change. Here we describe an action-planning framework to engage providers in reducing overused services. The framework is informed by a comprehensive review of social science theory and literature, published reports of successful and unsuccessful efforts to reduce low-value care, and interviews with innovators of value-based care initiatives in twenty-three health care organizations across the United States. A multi-stakeholder advisory committee provided feedback on the framework and guidance on optimizing it for use in practice. The framework describes four conditions necessary for change: prioritize addressing low-value care; build a culture of trust, innovation and improvement; establish shared language and purpose; and commit resources to measurements. These conditions foster productive sense-making conversations between providers, between providers and patients, and among members of the health care team about the potential for harm from overuse and reflection on current frequency of use. Through these conversations providers, patients and team members think together as a group, learn how to coordinate individual behaviors, and jointly develop possibilities for coordinated action around specific areas of overuse. Organizational efforts to engage providers in value-based care focused on creating conditions for productive sense-making conversations that lead to change. Organizations can use this framework to enhance and strengthen provider engagement efforts to do less of what potentially harms and more of what truly helps patients. Copyright © 2016 The Authors.

  2. Cultural change, hybridity and male homosexuality in Mexico.

    Carrillo, H

    1999-01-01

    This paper analyzes how contemporary perceptions of male homosexuality are being shaped in Mexico. Ethnographic analysis included four short case studies from 64 mostly middle class individuals for two years in Guadalajara City. Mexican sexual culture is often portrayed traditionally as grounded in values inherent in machismo and influenced by Catholicism. There is a contrast between these traditional interpretations of roles and sexual identities in Mexico and the identities that are being adopted by many contemporary Mexican homosexual men. The homosexual men were categorizable in terms of 1) those who dominated in the sexual relationship and who were capable of maintaining a nonstigmatized identity as regular men, 2) those who assumed a feminine role and were penetrated and who were stigmatized for their effeminate demeanor, and 3) a minority of men who assumed both roles and who were termed "anally active and passive". The study revealed that middle-class homosexuals established networks in which individuals, supported by their friends, acquired the strength to effect personal changes along with other larger cultural changes. Thus, individual actions are beginning to have a collective effect on the society at large.

  5. Innovation policy for directing technical change in the power sector

    Aalbers, Rob; Shestalova, Victoria; Kocsis, Viktória

    2013-01-01

    This paper discusses policy instruments for redirecting technical change within the electricity sector to mitigate climate change. First, we unravel the mechanism behind directed technical change, explaining why markets may underprovide innovations in expensive renewable technologies in comparison to innovations in energy-efficient fossil-fuel generators. Subsequently, we characterize technical change in electricity generation technologies, stressing the heterogeneity of knowledge spillovers both within and between clean electricity generation technologies. We argue that there exists a rationale for a portfolio approach to innovation in the electricity sector, i.e., optimal innovation policies are neither fully generic nor fully specific; and they need to be adapted, in response to new information learned by the government. The existing innovation literature does not, however, provide a clear-cut answer for designing such a policy. We compare policy instruments and argue that public R and D support to clean technologies, either in the form of subsidies or prizes, seems to be the prime candidate for implementing non-generic innovation policy. - Highlights: • We analyze policies for spurring innovations in renewable electricity technologies. • The analysis unravels why research markets underprovide such innovations. • We conclude that non-generic R and D subsidies and prizes are the most suitable policies

    Full Text Available The article is aimed at building a cognitive map using the method of gradually formalizing the decision making tasks – cognitive modeling to forecast the impact of organizational changes on the emergence of staff resistance to these changes and the use of an appropriate set of incentives to overcome the resistance. The theoretical generalization of existing research on cognitive modeling has led to the development of scenarios reflecting the impact of relevant organizational changes on the respective types of staff resistance and the impact of a particular set of incentives to overcome this resistance. The concepts in the system of «organizational changes – incentives – resistance» have been chosen the types of organizational change, the types of resistance that arise depending on the type of change in enterprise and the incentives to implement organizational changes. In general, 17 development scenarios for development of the system of «organizational changes – incentives – resistance» have been developed, of which 2-3 scenarios are envisaged for each of the organizational changes introduced in spheres such as organizational structure, equipment, technology, organizational culture, enterprise strategy, system of qualifying, hierarchy, standards and norms. Prospect for further research in this direction is the determination of staff readiness to implement organizational changes at the individual and organizational levels, and its evaluation.

    Full Text Available Rapid identification and determination of the antibiotic susceptibility profiles of the infectious agents in patients with bloodstream infections are critical steps in choosing an effective targeted antibiotic for treatment. However, there has been minimal effort focused on developing combined methods for the simultaneous direct identification and antibiotic susceptibility determination of bacteria in positive blood cultures. In this study, we constructed a lysis-centrifugation-wash procedure to prepare a bacterial pellet from positive blood cultures, which can be used directly for identification by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS and antibiotic susceptibility testing by the Vitek 2 system. The method was evaluated using a total of 129 clinical bacteria-positive blood cultures. The whole sample preparation process could be completed in <15 min. The correct rate of direct MALDI-TOF MS identification was 96.49% for gram-negative bacteria and 97.22% for gram-positive bacteria. Vitek 2 antimicrobial susceptibility testing of gram-negative bacteria showed an agreement rate of antimicrobial categories of 96.89% with a minor error, major error, and very major error rate of 2.63, 0.24, and 0.24%, respectively. Category agreement of antimicrobials against gram-positive bacteria was 92.81%, with a minor error, major error, and very major error rate of 4.51, 1.22, and 1.46%, respectively. These results indicated that our direct antibiotic susceptibility analysis method worked well compared to the conventional culture-dependent laboratory method. Overall, this fast, easy, and accurate method can facilitate the direct identification and antibiotic susceptibility testing of bacteria in positive blood cultures.

  9. A change of direction in the Dutch health care system?

    Lapré, R M

    1988-08-01

    The Dutch health care system seems to be undergoing a clear change of direction. The publication of the Report of the Committee of the Structure and Financing of the Health Care System is a prominent document which marks the emergence of a new trend. After an analysis of the characteristics of the Dutch health care system in the periods 1960-1975 and 1975-1985, an account is given of the most important proposals of the committee. The proposals clearly alter the trend towards more governmental involvement. They envisage a more market-oriented approach and freedom of operation while at the same time paying attention to aspects such as solidarity and social justice. The Committee's suggestions include the introduction of a basic insurance scheme for every citizen with a coverage determined by law, and in addition a voluntary supplementary insurance scheme in which the insured can decide what coverage he requires and that the insurer is obliged to accept him. The fact that there is a certain amount of agreement, at least over the direction that the strategy for change should take, justifies the expectation that many of the committee's proposals will be implemented.

    Methanol and ethanol have recently received much attention as liquid fuels particularly as alternative 'energy-vectors' for the future. In this sense, to find a direct alcohol fuel cell that able to interchange the fuel without losing performances in an appreciable way would represent an evident advantage in the field of portable applications. In this work, the response of a in-house direct methanol fuel cell (DMFC) to the change of fuel from methanol to ethanol and its behaviour at different ambient temperature values have been investigated. A corrosion study on materials suitable to fabricate the bipolar plates has been carried out and either 316- or 2205-duplex stainless steels have proved to be adequate for using in direct alcohol fuel cells. Polarization curves have been measured at different ambient temperature values, controlled by an experimental setup devised for this purpose. Data have been fitted to a model taking into account the temperature effect. For both fuels, methanol and ethanol, a linear dependence of adjustable parameters with temperature is obtained. Fuel cell performance comparison in terms of open circuit voltage, kinetic and resistance is established. (author)

    Crystalline Mg-Zinc (Zn)-Strontium (Sr) ternary alloys consist of elements naturally present in the human body and provide attractive mechanical and biodegradable properties for a variety of biomedical applications. The first objective of this study was to investigate the degradation and cytocompatibility of four Mg-4Zn-xSr alloys (x = 0.15, 0.5, 1.0, 1.5 wt%; designated as ZSr41A, B, C, and D respectively) in the direct culture with human umbilical vein endothelial cells (HUVEC) in vitro. The second objective was to investigate, for the first time, the early-stage inflammatory response in cultured HUVECs as indicated by the induction of vascular cellular adhesion molecule-1 (VCAM-1). The results showed that the 24-h in vitro degradation of the ZSr41 alloys containing a β-phase with a Zn/Sr at% ratio ~1.5 was significantly faster than the ZSr41 alloys with Zn/Sr at% ~1. Additionally, the adhesion density of HUVECs in the direct culture but not in direct contact with the ZSr41 alloys for up to 24 h was not adversely affected by the degradation of the alloys. Importantly, neither culture media supplemented with up to 27.6 mM Mg2+ ions nor media intentionally adjusted up to alkaline pH 9 induced any detectable adverse effects on HUVEC responses. In contrast, the significantly higher, yet non-cytotoxic, Zn2+ ion concentration from the degradation of ZSr41D alloy was likely the cause for the initially higher VCAM-1 expression on cultured HUVECs. Lastly, analysis of the HUVEC-ZSr41 interface showed near-complete absence of cell adhesion directly on the sample surface, most likely caused by either a high local alkalinity, change in surface topography, and/or surface composition. The direct culture method used in this study was proposed as a valuable tool for studying the design aspects of Zn-containing Mg-based biomaterials in vitro, in order to engineer solutions to address current shortcomings of Mg alloys for vascular device applications.

    Rapid identification and determination of the antibiotic susceptibility profiles of the infectious agents in patients with bloodstream infections are critical steps in choosing an effective targeted antibiotic for treatment. However, there has been minimal effort focused on developing combined methods for the simultaneous direct identification and antibiotic susceptibility determination of bacteria in positive blood cultures. In this study, we constructed a lysis-centrifugation-wash procedure to prepare a bacterial pellet from positive blood cultures, which can be used directly for identification by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS) and antibiotic susceptibility testing by the Vitek 2 system. The method was evaluated using a total of 129 clinical bacteria-positive blood cultures. The whole sample preparation process could be completed in identification was 96.49% for gram-negative bacteria and 97.22% for gram-positive bacteria. Vitek 2 antimicrobial susceptibility testing of gram-negative bacteria showed an agreement rate of antimicrobial categories of 96.89% with a minor error, major error, and very major error rate of 2.63, 0.24, and 0.24%, respectively. Category agreement of antimicrobials against gram-positive bacteria was 92.81%, with a minor error, major error, and very major error rate of 4.51, 1.22, and 1.46%, respectively. These results indicated that our direct antibiotic susceptibility analysis method worked well compared to the conventional culture-dependent laboratory method. Overall, this fast, easy, and accurate method can facilitate the direct identification and antibiotic susceptibility testing of bacteria in positive blood cultures.

  15. Healthcare organizational performance: why changing the culture really matters. Commentary.

    Azzolini, Elena; Ricciardi, Walter; Gray, Muir

    2018-01-01

    An organization may be considered as having three components: a structure, systems and culture. Culture is the most difficult part of the organization to affect. After all, culture has the key role in impacting and improving organizational performance. The leadership of an organization and its key operations are paramount in shaping the culture. Leadership and organizational culture are inextricably intertwined. They are two sides of the same coin. Culture is a medium through which leadership travels and impacts organizational performance. If leaders are to fulfil the challenges of the 21st century, they must first understand the dynamics of culture and their role as sculptors through behavioural and cognitive ways.

  17. Changing the Culture of Science Communication Training for Junior Scientists

    Bankston, Adriana; McDowell, Gary S.

    2018-01-01

    Being successful in an academic environment places many demands on junior scientists. Science communication currently may not be adequately valued and rewarded, and yet communication to multiple audiences is critical for ensuring that it remains a priority in today’s society. Due to the potential for science communication to produce better scientists, facilitate scientific progress, and influence decision-making at multiple levels, training junior scientists in both effective and ethical science communication practices is imperative, and can benefit scientists regardless of their chosen career path. However, many challenges exist in addressing specific aspects of this training. Principally, science communication training and resources should be made readily available to junior scientists at institutions, and there is a need to scale up existing science communication training programs and standardize core aspects of these programs across universities, while also allowing for experimentation with training. We propose a comprehensive core training program be adopted by universities, utilizing a centralized online resource with science communication information from multiple stakeholders. In addition, the culture of science must shift toward greater acceptance of science communication as an essential part of training. For this purpose, the science communication field itself needs to be developed, researched and better understood at multiple levels. Ultimately, this may result in a larger cultural change toward acceptance of professional development activities as valuable for training scientists. PMID:29904538

  19. African Cultural Concept of Death and the Idea of Advance Care Directives.

    Ekore, Rabi Ilemona; Lanre-Abass, Bolatito

    2016-01-01

    An advance care directive is a person's oral or written instructions about his or her future medical care, if he or she becomes unable to communicate. It may be in written or oral form. Africans ordinarily do not encourage the contemplation of death or any discussion about their own or their loved ones' death. According to the African belief system, life does not end with death, but continues in another realm. Becoming an ancestor after death is a desirable goal of every individual, a feat which cannot be achieved if an individual asks for an unnatural death by attempting to utilize advance care directives. Advance care directives are considered to be too individualistic for communitarian societies such as Africa. Coupled with the communitarian nature of African societies are issues such as lack of awareness of advance directives, fear of death and grief, and the African cultural belief system, which are potential barriers to the utilization of advance care directives in the African setting. Hence, the need for culture sensitivity which makes it imperative that patient's family and loved ones are carried along as far as possible, without compromising the autonomy of the patient in question when utilizing advance care directives.

    2010-04-01

    Full Text Available Trichomonas vaginalis is a flagellate protozoan that lives in the genital tract and causes trichomoniasis in women. About 200 million people all over the world are infected with T. vaginalis. There are various methods with different sensitivity and specificity for detection of this parasite, that one of them is direct smear of vaginal secretions which is simpler, rapid and cheaper than other diagnostic methods. Materials and Methods: Demographic data was gathered by a questionnaire which contained different variables. Vaginal secretions samples were taken by spicolum and two swaps that maintained in glucose solution in separate tubes from 160 women referred to health centers of Khorramabad. One of the vaginal samples was examined by direct smear in saline solution and the other was cultured in Dorse medium. Results: Of 160 women suspected of trichomoniasis, 11.8% and 18.75% were positive by direct smear and culture respectively. The sensitivity of the direct method was 63.3%. Our findings indicated that 30% of the infected women belonged to the 31 – 35 age group, which had the most relative frequency of positive cases. Most of the patients (43% were illiterate or had elementary educational level. Conclussion: The sensivity of direct method is 63% in compare to culture ( as a Gold standard , which is ralatively low . Although the efficacy of this test could be imporved by shortening the elapsed time between sampling and examination , use of skilled microscopists , and different samples , but we recommend that more sensitive methods such as culture and PCR should be used .

  1. Postmodern messiahs: the changing saviours of contemporary popular culture

    Sofia Sjö

    2009-01-01

    Full Text Available The messiah myth is alive and well in the modern world. Contemporary science fiction film has taken the myth to heart and given us an endless stream of larger than life heroes. The heroes of the present are, however, not exactly the same as the heroes of the past. A changing world demands new things of its saviours. Using a textual and narrative analysis based on insights gained from feminist film theory and cultural studies, this article looks closely at the messiah theme in science fiction films and TV series from the last three decades. The study explores the changes that have occurred in relation to images of the body, the attitudes and personalities of modern heroes, gender, questions of power and ideas of the transcendent. The article then discusses what these changes both between newer and older heroes and between contemporary heroes and the traditional messiah story might say about religion and spirituality in the modern world. Finally the article explores the question of why the messiah myth still finds an audience today.

  5. Direct identification from Bact/Alert™ blood culture bottles by MALDI-TOF

    Vesselina Kroumova

    2011-12-01

    Full Text Available Bacterial identification from blood culture using traditional methods needs about 48 hours, since positivization, to be performed. Rapid bacterial identification can result in clinical and economic benefits. To provide rapid pathogen identification for targeted antibiotic treatment, in this study we tested an our previously described homemade method for bacterial identification using MALDI-TOF directly from positive BACTEC blood culture, on positive BacT/ALERT blood culture. A total of 108 bacteria were identified by MALDI-TOF with a positive identification obtained for 98% of Gram negative and 84,3% of Gram positive bacteria.The average of identification score obtained using the protocol described in this study was 2,047 for Gram positive and 2,204 for Gram negative microorganisms. Data here described show that this method is also useful when BacT/ALERT bottles are used and even if these bottles have activated charcoal as inhibitor of antibiotics.

  6. Developing a mesophilic co-culture for direct conversion of cellulose to butanol in consolidated bioprocess.

    Wang, Zhenyu; Cao, Guangli; Zheng, Ju; Fu, Defeng; Song, Jinzhu; Zhang, Junzheng; Zhao, Lei; Yang, Qian

    2015-01-01

    Consolidated bioprocessing (CBP) of butanol production from cellulosic biomass is a promising strategy for cost saving compared to other processes featuring dedicated cellulase production. CBP requires microbial strains capable of hydrolyzing biomass with enzymes produced on its own with high rate and high conversion and simultaneously produce a desired product at high yield. However, current reported butanol-producing candidates are unable to utilize cellulose as a sole carbon source and energy source. Consequently, developing a co-culture system using different microorganisms by taking advantage of their specific metabolic capacities to produce butanol directly from cellulose in consolidated bioprocess is of great interest. This study was mainly undertaken to find complementary organisms to the butanol producer that allow simultaneous saccharification and fermentation of cellulose to butanol in their co-culture under mesophilic condition. Accordingly, a highly efficient and stable consortium N3 on cellulose degradation was first developed by multiple subcultures. Subsequently, the functional microorganisms with 16S rRNA sequences identical to the denaturing gradient gel electrophoresis (DGGE) profile were isolated from consortium N3. The isolate Clostridium celevecrescens N3-2 exhibited higher cellulose-degrading capability was thus chosen as the partner strain for butanol production with Clostridium acetobutylicum ATCC824. Meanwhile, the established stable consortium N3 was also investigated to produce butanol by co-culturing with C. acetobutylicum ATCC824. Butanol was produced from cellulose when C. acetobutylicum ATCC824 was co-cultured with either consortium N3 or C. celevecrescens N3-2. Co-culturing C. acetobutylicum ATCC824 with the stable consortium N3 resulted in a relatively higher butanol concentration, 3.73 g/L, and higher production yield, 0.145 g/g of glucose equivalent. The newly isolated microbial consortium N3 and strain C. celevecrescens N3

    The carbohydrates of sweet sorghum were directly converted to ethanol by a mixed culture of Fusarium oxysporum F3 and Saccharomyces cerevisiae 2541. A number of factors affecting this bioconversion was studied. Optimum ethanol yields of 33.2 g/100 g of total sorghum carbohydrates, corresponding to 10.3 g/100 g of fresh stalks, were obtained. These values represented 68.6% of the theoretical yield based on total polysaccharides and exceeded that based on oligosaccharides of sorghum by 53.7%. The results demonstrated that more than half of the sorghum polysaccharides were directly fermented to ethanol, thus making the process worthy of further investigation. (author)

  13. Age related changes in steroid receptors on cultured lung fibroblasts

    Barile, F.A.; Bienkowski, R.S.

    1986-01-01

    The number of high affinity glucocorticoid receptors (Ro) on human fetal lung fibroblasts decreases as the cells age in vitro, and it has been suggested that these cell systems may be useful models of age-related changes in vivo. They examined the relation between change in Ro with in vitro aging and donor age. Confluent monolayers of lung fibroblasts at various population doubling levels (PDL), were incubated with ( 3 H)-dexamethasone (( 3 H)Dex) either alone or with excess (.01 mM) Dex. Specific binding was calculated as the difference between radioactivity in cells incubated with and without unlabeled Dex; Scatchard plots were used to analyze the data. Ro, measured as fmol ( 3 H)Dex/10 6 cells, for two lines of human fetal cells (HFL-1 and MRC-5) decreased with increasing age in vitro. However, human newborn (CRL-1485) and adult (CCL-201) cells and fetal rabbit cells (FAB-290), showed increases in Ro with continuous passage. For each cell line, the affinity constant (K/sub d/) did not change significantly with passage. They conclude that the direction of changes in steroid receptor levels on cells aging in vitro is influenced by donor age and species. Caution should be used in applying results obtained from model systems to aging organisms

  15. Bi-directional exchange of membrane components occurs during co-culture of mesenchymal stem cells and nucleus pulposus cells.

    Strassburg, Sandra; Hodson, Nigel W; Hill, Patrick I; Richardson, Stephen M; Hoyland, Judith A

    2012-01-01

    Mesenchymal stem cell (MSC)-based therapies have been proposed as novel treatments for intervertebral disc (IVD) degeneration. We have previously demonstrated that when MSCs are co-cultured with nucleus pulposus (NP) cells with direct cell-cell contact, they differentiate along the NP lineage and simultaneously stimulate the degenerate NP cell population to regain a normal (non-degenerate) phenotype, an effect which requires cell-cell communication. However, the mechanisms by which NP cells and MSCs interact in this system are currently unclear. Thus, in this study we investigated a range of potential mechanisms for exchange of cellular components or information that may direct these changes, including cell fusion, gap-junctional communication and exchange of membrane components by direct transfer or via microvesicle formation. Flow cytometry of fluorescently labeled MSCs and NP cells revealed evidence of some cell fusion and formation of gapjunctions, although at the three timepoints studied these phenomena were detectable only in a small proportion of cells. While these mechanisms may play a role in cell-cell communication, the data suggests they are not the predominant mechanism of interaction. However, flow cytometry of fluorescently dual-labeled cells showed that extensive bi-directional transfer of membrane components is operational during direct co-culture of MSCs and NP cells. Furthermore, there was also evidence for secretion and internalization of membrane-bound microvesicles by both cell types. Thus, this study highlights bi-directional intercellular transfer of membrane components as a possible mechanism of cellular communication between MSC and NP cells.

  16. Culturally compelling strategies for behaviour change: a social ecology model and case study in malaria prevention.

    Panter-Brick, Catherine; Clarke, Sian E; Lomas, Heather; Pinder, Margaret; Lindsay, Steve W

    2006-06-01

    Behaviour change is notoriously difficult to initiate and sustain, and the reasons why efforts to promote healthy behaviours fail are coming under increasing scrutiny. To be successful, health interventions should build on existing practices, skills and priorities, recognise the constraints on human behaviour, and either feature community mobilisation or target those most receptive to change. Furthermore, interventions should strive to be culturally compelling, not merely culturally appropriate: they must engage local communities and nestle within social and ecological landscapes. In this paper, we propose a social ecology perspective to make explicit the links between intention to change, actual behaviour change, and subsequent health impact, as relating to both theory-based models and practical strategies for triggering behaviour change. A social ecology model focuses attention on the contexts of behaviour when designing, implementing or critically evaluating interventions. As a case study, we reflect on a community-directed intervention in rural Gambia designed to reduce malaria by promoting a relatively simple and low-cost behaviour: repairing holes in mosquito bednets. In phase 1, contextual information on bednet usage, transactions and repairs (the 'social lives' of nets) was documented. In phase 2 (intervention), songs were composed and posters displayed by community members to encourage repairs, creating a sense of ownership and a compelling medium for the transmission of health messages. In phase 3 (evaluation), qualitative and quantitative data showed that household responses were particularly rapid and extensive, with significant increase in bednet repairs (psocial ecology-of behaviour practices that are the bedrock of health interventions.

  17. Conceptualizing the Research Culture in Postgraduate Medical Education: Implications for Leading Culture Change.

    O'Brien, Jennifer M

    2015-12-01

    By recognizing symbols of research culture in postgraduate medical education, educators and trainees can gain a deeper understanding of the existing culture and mechanisms for its transformation. First, I identify symbolic manifestations of the research culture through a case narrative of a single anesthesia residency program, and I offer a visual conceptualization of the research culture. In the second part, I theorize the application of Senge's (1994) disciplines of a learning organization and discuss leverage for enhancing research culture. This narrative account is offered to inform the work of enhancing the broader research culture in postgraduate medical education.

  19. TOURISM POLICY IN ROMANIA: A NECESSARY CHANGE OF DIRECTION

    Vasile DINU

    2009-06-01

    Full Text Available In modern economies services are dominant. As the role of services is increasing, the difference between goods and services is vanishing, but most of our economics and business knowledge is developed from a manufacturing perspective which is no more satisfactory in the new service economy conditions. One important aspect is that the ability of a country to participate effectively to the growing international trade in services depends more and more on its attractiveness as a visitors' destination. Although there is a well developed understanding of the role of tourism to the general economic and social development, it is less understood the effect of economic and social living conditions as visitor attractiveness factors.Reviewing recent studies, assessments and reports regarding the travel & tourism economy of Romania, authors found out that achieving the economic potential of tourism faces serious challenges due, primarily, to the discrepancy between the conditions visitors are increasingly looking for and the conditions provided by Romanian destinations. In order to accept the challenges with chances of success the tourism policy making should radically change direction. The authors identify three main priorities: focus on general development, put policy in the service of visitors first, improve communication and branding.

  20. Directed technical change and differentiation of climate policy

    Otto, Vincent M.; Loeschel, Andreas; Reilly, John

    2008-01-01

    This paper studies the cost effectiveness of climate policy if there are technology externalities. For this purpose, we develop a forward looking model that captures empirical links between CO 2 emissions associated with energy use, directed technical change and the economy. We find our most cost effective climate policy to include a combination of R and D subsidies and CO 2 emission constraints, although R and D subsidies raise the shadow value of the CO 2 constraint (i.e. CO 2 price) because of a strong rebound effect from stimulating innovation. Furthermore, we find that cost effectiveness of climate policy improves if it is differentiated between technologies. Even our rudimentary distinction between CO 2 intensive technologies and non-CO 2 intensive technologies lead to this result. Such differentiated climate policy encourages growth in the non-CO 2 intensive sectors and discourages growth in CO 2 intensive sectors by harnessing positive effects of technology externalities on total factor productivity in the former and letting the latter bear relatively more of the abatement burden. This result is robust to whether emission constraints, R and D subsidies or combinations of both are used as climate policy instruments. (author)

  1. A generative inference framework for analysing patterns of cultural change in sparse population data with evidence for fashion trends in LBK culture.

    Kandler, Anne; Shennan, Stephen

    2015-12-06

    Cultural change can be quantified by temporal changes in frequency of different cultural artefacts and it is a central question to identify what underlying cultural transmission processes could have caused the observed frequency changes. Observed changes, however, often describe the dynamics in samples of the population of artefacts, whereas transmission processes act on the whole population. Here we develop a modelling framework aimed at addressing this inference problem. To do so, we firstly generate population structures from which the observed sample could have been drawn randomly and then determine theoretical samples at a later time t2 produced under the assumption that changes in frequencies are caused by a specific transmission process. Thereby we also account for the potential effect of time-averaging processes in the generation of the observed sample. Subsequent statistical comparisons (e.g. using Bayesian inference) of the theoretical and observed samples at t2 can establish which processes could have produced the observed frequency data. In this way, we infer underlying transmission processes directly from available data without any equilibrium assumption. We apply this framework to a dataset describing pottery from settlements of some of the first farmers in Europe (the LBK culture) and conclude that the observed frequency dynamic of different types of decorated pottery is consistent with age-dependent selection, a preference for 'young' pottery types which is potentially indicative of fashion trends. © 2015 The Author(s).

  2. Should varicella-zoster virus culture be eliminated? A comparison of direct immunofluorescence antigen detection, culture, and PCR, with a historical review.

    A comparison of direct fluorescent-antibody assay (DFA), culture, and two PCR assays disclosed sensitivities of 87.8%, 46.3%, and 97.6% and 100%, respectively. We reviewed 1,150 results for clinical specimens submitted for DFA and culture and found that only 17 were culture positive/DFA negative. The incremental cost to detect these 17 positives was $3,078/specimen.

  4. Cross-Cultural Register Differences in Infant-Directed Speech: An Initial Study.

    Lama K Farran

    Full Text Available Infant-directed speech (IDS provides an environment that appears to play a significant role in the origins of language in the human infant. Differences have been reported in the use of IDS across cultures, suggesting different styles of infant language-learning. Importantly, both cross-cultural and intra-cultural research suggest there may be a positive relationship between the use of IDS and rates of language development, underscoring the need to investigate cultural differences more deeply. The majority of studies, however, have conceptualized IDS monolithically, granting little attention to a potentially key distinction in how IDS manifests across cultures during the first two years. This study examines and quantifies for the first time differences within IDS in the use of baby register (IDS/BR, an acoustically identifiable type of IDS that includes features such as high pitch, long duration, and smooth intonation (the register that is usually assumed to occur in IDS, and adult register (IDS/AR, the type of IDS that does not include such features and thus sounds as if it could have been addressed to an adult. We studied IDS across 19 American and 19 Lebanese mother-infant dyads, with particular focus on the differential use of registers within IDS as mothers interacted with their infants ages 0-24 months. Our results showed considerable usage of IDS/AR (>30% of utterances and a tendency for Lebanese mothers to use more IDS than American mothers. Implications for future research on IDS and its role in elucidating how language evolves across cultures are explored.

    Antarctic and Southern Ocean (ASO) marine ecosystems have been changing for at least the last 30 years, including in response to increasing ocean temperatures and changes in the extent and seasonality of sea ice; the magnitude and direction of these changes differ between regions around Antarctica that could see populations of the same species changing differently in different regions. This article reviews current and expected changes in ASO physical habitats in response to climate change. It then reviews how these changes may impact the autecology of marine biota of this polar region: microbes, zooplankton, salps, Antarctic krill, fish, cephalopods, marine mammals, seabirds, and benthos. The general prognosis for ASO marine habitats is for an overall warming and freshening, strengthening of westerly winds, with a potential pole-ward movement of those winds and the frontal systems, and an increase in ocean eddy activity. Many habitat parameters will have regionally specific changes, particularly relating to sea ice characteristics and seasonal dynamics. Lower trophic levels are expected to move south as the ocean conditions in which they are currently found move pole-ward. For Antarctic krill and finfish, the latitudinal breadth of their range will depend on their tolerance of warming oceans and changes to productivity. Ocean acidification is a concern not only for calcifying organisms but also for crustaceans such as Antarctic krill; it is also likely to be the most important change in benthic habitats over the coming century. For marine mammals and birds, the expected changes primarily relate to their flexibility in moving to alternative locations for food and the energetic cost of longer or more complex foraging trips for those that are bound to breeding colonies. Few species are sufficiently well studied to make comprehensive species-specific vulnerability assessments possible. Priorities for future work are discussed. © 2014 John Wiley & Sons Ltd.

  7. A continuous culture system of direct somatic embryogenesis in microspore-derived embryos of Brassica juncea.

    Prabhudesai, V; Bhaskaran, S

    1993-03-01

    An efficient culture system has been developed for repeated cycles of somatic embryogenesis in microspore-derived embryos of Brassica juncea without a callus phase. Haploid embryos produced through anther culture showed a high propensity for direct production of somatic embryos in response to 2 mgL(-1) BA and 0.1 mgL(-1) NAA. The embryogenic cultures which comprised the elongated embryonal axis of microspore-derived embryos when explanted and grown on the medium of same composition produced a large number of secondary embryos. These somatic embryos in turn underwent axis elongation and produced more somatic embryos when explanted and cultured. This cycle of repetitive somatic embryogenesis continued with undiminished vigour passage after passage and was monitored for more than a year. Somatic embryos from any passage when isolated at cotyledonary stage and grown on auxin-free medium for 5 days and then on a medium containing NAA (0.1 mgL(-1)), developed into complete plants with a profuse root system and were easily established in the soil. The cytology of the root tips of these plants confirmed their haploid nature. The total absence of callus phase makes the system ideal for continuous cloning of androgenic lines, Agrobacterium-mediated transformation and mutation induction studies.

  8. Changing gender relations in Thailand: a historical and cultural analysis.

    Tantiwiramanond, D

    1997-01-01

    In response to the stereotyping of Thai women in the media as either modern businesswomen or victims of male oppression, this article studies the changing gender roles and status of women in Thailand to identify the various roles played by Thai women and the ways these roles are linked to key cultural, economic, and political mechanisms in Thai society. After an introduction, the first section of the paper analyzes pre-modern Thai history from the mid-13th century with a look at the traditional social, political, and economic structure of feudal society to determine how women's status was affected by Thai Buddhism, absolute monarchy (the affect of the legal system on upper-class women), and matrifocal kinship (the effect of subsistence agriculture on lower-class women). This section also compares the historic status of upper- and lower-class Thai women. The second section of the article considers the effects of 1) the encroachment of Western colonialism in Southeast Asia during the period 1850-1925 and attendant criticisms of polygamy, 2) the post-1932 revolution that resulted in a constitutional monarchy, and 3) the post 1950s period of economic nationalism that has resulted in globalization. The article concludes that lower-class women have certain rights under the feudal system (before 1932) but were forced into certain roles by economic necessity and motherhood. Upper-class women enjoyed high status, but all women were victims of the Buddhist patriarchy and hierarchical systems. Western modernization caused a decline in polygamy and new opportunities for educated women but the status of Thai women has not changed substantially, and class-specific forms of female oppression continues unabated making lower-class women vulnerable to sexual exploitation.

  9. THE ROLE OF CULTURAL CHANGES IN INTERGENERATIONAL CONFLICTS IN ORGANIZATIONAL PROCESSES: A SURVEY AIMED AT ACADEMICIANS

    Full Text Available The phenomenon of change in the cultural structure brought about differences in values, beliefs and behavior in the social structure. The fact that the phenomenon of change is not acknowledged by adult generations, the inability to understand the behaviors of new generations brings about the possibility of conflicts between new and adult generations. The conflicts that individuals primarily experience in the family environment also manifest themselves when they are beginning to work within an institution. Many theoretical-based studies in the literature show that conflicts that occur during generations may be related to cultural changes. In the study, it was tried to determine whether the X generation academicians working at the universities had experienced conflict with the Y generation of the younger generation. In addition, the Y generation academics were investigated whether they lived in conflict with the elderly generations, named  X generation,, Baby Boomers generation and silent generation. In addition in the survey; the relation between the avoidance of variables measuring the cultural dimensions and uncertainty, power distance, collectivism I, collectivism II, assertiveness, gender segregation, being orientation for future and performance, differentiations in humanistic approach and intergenerational conflicts are searched. Data are collected over the web sites by survey method, face to face meeting and via fax and 428 applicable interview results have been provided.  In the analysis of the data, the structural equality model was utilized. As a result of the analyzes made; It has been determined that the X generation is rarely conflict with Y generation, the Y generation is rarely conflict with X generation, Baby Boomers generation and silent generation. Collectivism II and performance orientation and relation of intergenerational conflicts has been found in reverse direction where the relation of intergenerational conflicts with

    Tuberculosis culture usually requires sputum decontamination and centrifugation to prevent cultures from being overgrown by contaminating bacteria and fungi. However, decontamination destroys many tuberculous bacilli, and centrifugation often is not possible in resource-poor settings. We therefore assessed the performance of Mycobacterium tuberculosis culture with unprocessed samples plated directly by using tuberculosis-selective media and compared this procedure to conventional culture using centrifuge decontamination. Quadruplicate aliquots of strain H37RV were cultured in 7H9 broth with and without selective antimicrobials and after centrifuge decontamination. The subsequent comparison was made with 715 sputum samples. Split paired sputum samples were cultured conventionally with centrifuge decontamination and by direct culture in tuberculosis-selective media containing antibiotics. Centrifuge decontamination reduced tuberculosis H37RV colonies by 78% (P laboratories this deficit may be outweighed by the ease of use.

  12. Direct induction of chondrogenic cells from human dermal fibroblast culture by defined factors.

    Hidetatsu Outani

    Full Text Available The repair of large cartilage defects with hyaline cartilage continues to be a challenging clinical issue. We recently reported that the forced expression of two reprogramming factors (c-Myc and Klf4 and one chondrogenic factor (SOX9 can induce chondrogenic cells from mouse dermal fibroblast culture without going through a pluripotent state. We here generated induced chondrogenic (iChon cells from human dermal fibroblast (HDF culture with the same factors. We developed a chondrocyte-specific COL11A2 promoter/enhancer lentiviral reporter vector to select iChon cells. The human iChon cells expressed marker genes for chondrocytes but not fibroblasts, and were derived from non-chondrogenic COL11A2-negative cells. The human iChon cells formed cartilage but not tumors in nude mice. This approach could lead to the preparation of cartilage directly from skin in human, without going through pluripotent stem cells.

  13. Theoretical foundations guiding culture change: The work of the Partnerships in Dementia Care Alliance.

    Dupuis, Sherry; McAiney, Carrie A; Fortune, Darla; Ploeg, Jenny; Witt, Lorna de

    2016-01-01

    Longstanding concerns about quality care provision, specifically in the area of long-term care, have prompted calls for changing the culture of care to reflect more client-driven and relationship-centred models. Despite an increase in culture change initiatives in both Canada and the United States, there is insufficient information about the theories and approaches that guide culture change. The purpose of this paper is to describe a culture change initiative currently underway in Canada, the Partnerships in Dementia Care Alliance, and the theoretical foundations informing our work. More specifically, we describe how the theoretical and philosophical underpinnings of the Alzheimer Disease and Related Dementias framework, the authentic partnership approach, participatory action research and Appreciative Inquiry have been integrated to guide a culture change process that encourages working collaboratively, thinking and doing differently and re-imagining new possibilities for changing the culture of dementia care. © The Author(s) 2014.

  14. The influence of structural and institutional change on teaching and culture in clinical settings: an exploratory study.

    Goldie, J; Dowie, A; Goldie, Anne; Cotton, Phil; Morrison, Jill

    2015-02-01

    Learning in clinical settings is a function of activity, context and culture. Glasgow University's Medical School has undergone significant curricular change in recent years. This has coincided with change to National Health Service consultants' contracts, the introduction of the European Working Time Directive and the Modernising Medical Careers training initiative. We wished to explore teachers' and students' perspectives on the effects of change on our clinical teachers' capacity for teaching and on medical culture. A qualitative approach using individual interviews with educational supervisors and focus groups with senior clinical students was used. Data were analysed using a "framework" technique. Curricular change has led to shorter clinical attachments in the senior clinical rotation, which combined with more centralised teaching have had adverse effects on both formal and informal teaching during attachments. Consultants' NHS contract changes the implementation of the European Working Time Directive and changes to postgraduate training have adversely affected consultants' teaching capacity, which has had a detrimental effect on their relationships with students. Medical culture has also changed as a result of these and other societal influences. The apprenticeship model was still felt to be relevant in clinical settings. This has to be balanced against the need for systematic teaching. Structural and institutional change affects learning. Faculty needs to be aware of the socio-historical context of their institutions.

    Services to families have traditionally been delivered in a medical model. This presents challenges including workforce shortages, lack of cultural diversity, lack of training in strength-based work, and difficulty in successfully engaging and retaining families in the therapy process. The system of care (SOC) effort has worked to establish formal roles for caregivers in SOC to improve services. This paper provides an example of one community's efforts to change the SOC by expanding the roles available to caregivers in creating systems change. It describes the model developed by Communities of Care (CoC), a SOC in Central Massachusetts, and its evolution over a 10 year period. First person accounts by system partners, caregivers hired into professional roles as well as a family receiving services, demonstrate how hiring caregivers at all levels can change systems and change lives, not only for those being served but for the caregiver/professionals doing the work. It also demonstrates, however, that change at the system level is incremental, takes time, and can be fleeting unless an ongoing effort is made to support and sustain those changes.

  18. A new rapid method for direct antimicrobial susceptibility testing of bacteria from positive blood cultures.

    2016-08-12

    Rapid identification and antimicrobial susceptibility testing (AST) of the causative agent(s) of bloodstream infections can lead to prompt appropriate antimicrobial therapy. To shorten species identification, in this study bacteria were recovered from monomicrobial blood cultures by serum separator tubes and spotted onto the target plate for direct MALDI-TOF MS identification. Proper antibiotics were selected for direct AST based on species identification. In order to obtain rapid AST results, bacteria were recovered from positive blood cultures by two different protocols: by serum separator tubes (further referred to as PR1), or after a short-term subculture in liquid medium (further referred to as PR2). The results were compared with those obtained by the method currently used in our laboratory consisting in identification by MALDI-TOF and AST by Vitek 2 or Sensititre on isolated colonies. The direct MALDI-TOF method concordantly identified with the current method 97.5 % of the Gram-negative bacteria and 96.1 % of the Gram-positive cocci contained in monomicrobial blood cultures. The direct AST by PR1 and PR2 for all isolate/antimicrobial agent combinations was concordant/correct with the current method for 87.8 and 90.5 % of Gram-negative bacteria and for 93.1 and 93.8 % of Gram-positive cocci, respectively. In particular, 100 % categorical agreement was found with levofloxacin for Enterobacteriaceae by both PR1 and PR2, and 99.0 and 100 % categorical agreement was observed with linezolid for Gram-positive cocci by PR1 and PR2, respectively. There was no significant difference in accuracy between PR1 and PR2 for Gram-negative bacteria and Gram-positive cocci. This newly described method seems promising for providing accurate AST results. Most importantly, these results would be available in a few hours from blood culture positivity, which would help clinicians to promptly confirm or streamline an effective antibiotic therapy in patients with bloodstream

  19. Regulation of adipose-tissue-derived stromal cell orientation and motility in 2D- and 3D-cultures by direct-current electrical field.

    Cell alignment and motility play a critical role in a variety of cell behaviors, including cytoskeleton reorganization, membrane-protein relocation, nuclear gene expression, and extracellular matrix remodeling. Direct current electric field (EF) in vitro can direct many types of cells to align vertically to EF vector. In this work, we investigated the effects of EF stimulation on rat adipose-tissue-derived stromal cells (ADSCs) in 2D-culture on plastic culture dishes and in 3D-culture on various scaffold materials, including collagen hydrogels, chitosan hydrogels and poly(L-lactic acid)/gelatin electrospinning fibers. Rat ADSCs were exposed to various physiological-strength EFs in a homemade EF-bioreactor. Changes of morphology and movements of cells affected by applied EFs were evaluated by time-lapse microphotography, and cell survival rates and intracellular calcium oscillations were also detected. Results showed that EF facilitated ADSC morphological changes, under 6 V/cm EF strength, and that ADSCs in 2D-culture aligned vertically to EF vector and kept a good cell survival rate. In 3D-culture, cell galvanotaxis responses were subject to the synergistic effect of applied EF and scaffold materials. Fast cell movement and intracellular calcium activities were observed in the cells of 3D-culture. We believe our research will provide some experimental references for the future study in cell galvanotaxis behaviors. © 2017 Japanese Society of Developmental Biologists.

    Many refugee people and others entering Australia under the Humanitarian Program, have experienced extremely stressful and disrupted lives prior to arrival. A major difficulty experienced by a significant number of refugee young people is their lack of formal education before arrival. It directly affects their ability to start connecting to their new society and constructing a new life. The level of ease with which young people can move into the education and training system and begin to establish a meaningful career pathway has a huge impact on their successful settlement and stable mental health. This paper describes the Changing Cultures Project, a three-year project, which explored models of appropriate and accessible education and training for refugee and newly arrived young people that would enhance their mental health. The Changing Cultures Project was a partnership between the education, health and settlement sectors. This paper describes the program and system response to the health, settlement, education and vocational issues facing refugee young people using a mental health promotion framework and reflective practice. We discuss how the refugee youth programs met a broad range of needs as well as providing language, literacy and basic education to newly arrived young people. While working in an environment of changing policy and public opinion regarding refugee issues, the Project delivered successful outcomes at the program and organisational levels for refugee young people by addressing issues of program development and delivery, organisational development and capacity building and community development and evaluation.

    Climate change will have significant effects on the health of wildlife, domestic animals, and humans, according to scientists. The Intergovernmental Panel on Climate Change projects that unprecedented rates of climate change will result in increasing average global temperatures; rising sea levels; changing global precipitation patterns, including increasing amounts and variability; and increasing midcontinental summer drought (Intergovernmental Panel on Climate Change, 2007). Increasing temperatures, combined with changes in rainfall and humidity, may have significant impacts on wildlife, domestic animal, and human health and diseases. When combined with expanding human populations, these changes could increase demand on limited water resources, lead to more habitat destruction, and provide yet more opportunities for infectious diseases to cross from one species to another.

  5. Using transformational change to improve organizational culture and climate in a school of nursing.

    Springer, Pamela J; Clark, Cynthia M; Strohfus, Pamela; Belcheir, Marcia

    2012-02-01

    A positive organizational culture and climate is closely associated with an affirming workplace and job satisfaction. Especially during a time of faculty shortages, academic leaders need to be cognizant of the culture and climate in schools of nursing. The culture of an organization affects employees, systems, and processes, and if the culture becomes problematic, transformational leadership is essential to create change. The purpose of this article is to describe an 8-year journey to change the culture and climate of a school of nursing from one of dissatisfaction and distrust to one of high employee satisfaction and trust. Kotter's model for transformational change was used to frame a longitudinal study using the Cultural and Climate Assessment Scale to transform the organizational culture and climate of a school of nursing.

  6. The oldest anatomically modern humans from far southeast Europe: direct dating, culture and behavior.

    Sandrine Prat

    Full Text Available BACKGROUND: Anatomically Modern Humans (AMHs are known to have spread across Europe during the period coinciding with the Middle to Upper Paleolithic transition. Whereas their dispersal into Western Europe is relatively well established, evidence of an early settlement of Eastern Europe by modern humans are comparatively scarce. METHODOLOGY/PRINCIPAL FINDING: Based on a multidisciplinary approach for the study of human and faunal remains, we describe here the oldest AMH remains from the extreme southeast Europe, in conjunction with their associated cultural and paleoecological background. We applied taxonomy, paleoecology, and taphonomy combined with geomorphology, stratigraphy, archeology and radiocarbon dating. More than 160 human bone remains have been discovered. They originate from a well documented Upper Paleolithic archeological layer (Gravettian cultural tradition from the site of Buran-Kaya III located in Crimea (Ukraine. The combination of non-metric dental traits and the morphology of the occipital bones allow us to attribute the human remains to Anatomically Modern Humans. A set of human and faunal remains from this layer has been radiocarbon dated by Accelerator Mass Spectrometry. The direct-dating results of human bone establish a secure presence of AMHs at 31,900+240/-220 BP in this region. They are the oldest direct evidence of the presence of AMHs in a well documented archeological context. Based on taphonomical observations (cut marks and distribution of skeletal elements, they represent the oldest Upper Paleolithic modern humans from Eastern Europe, showing post-mortem treatment of the dead as well. CONCLUSION/SIGNIFICANCE: These findings are essential for the debate on the spread of modern humans in Europe during the Upper Paleolithic, as well as their cultural behaviors.

Based on taphonomical observations (cut marks and distribution of skeletal elements), they represent the oldest Upper Paleolithic modern humans from Eastern Europe, showing post-mortem treatment of the dead as well. These findings are essential for the debate on the spread of modern humans in Europe during the Upper Paleolithic, as well as their cultural behaviors.

  11. Cultural or Ecological Sustainability? The Effect of Cultural Change on Sabal Palm Management Among the Lowland Maya of Mexico

    Andrea Martínez-Ballesté

    2006-12-01

    Full Text Available Sabal palm has been used for thatching the traditional Maya house for over 3000 yr. The great importance of this resource has promoted its management within home gardens. Although traditionally managed populations in home gardens are capable of ecological long-term persistence, the impact of cultural change on sustainable resource management is poorly understood. By means of interviews in 108 households, we obtained information about Sabal management practices, leaf demand, and sociocultural data. Density and size structure of the palm populations in the respective home gardens were also measured. By means of principal components analysis, the sociocultural data were summarized into a cultural change index, which was then statistically related to palm density, size structure, leaf demand, and management practices. Leaf demand along the cultural change gradient was estimated. Sabal populations were affected by the cultural change index. Palm density and the proportion of harvestable individuals were higher in the more traditional households. The number of management practices decreased, and the probability of felling adult palms increased with cultural change. As a result, the percentage of the total leaf demand satisfied by home garden production diminished from 118.2-69.4% as cultural change increased. Traditional practices seem oriented to increasing the palm availability. Seed sowing and the protection of seedlings and adults affect the life stages with the largest impact on the population growth rate, as measured through sensitivity analysis. This means that abandoning traditional practices and felling adults more frequently should reduce rapidly, which is consistent with the low palm density observed in less traditional households. The application of demographic models to Sabal tells us that traditional management warrants the persistence of the resource as long as the current conditions remain unchanged. In contrast, our data show that

  12. Yersinia enterocolitica in slaughter pig tonsils: enumeration and detection by enrichment versus direct plating culture.

    Van Damme, Inge; Habib, Ihab; De Zutter, Lieven

    2010-02-01

    Tonsil samples from 139 slaughter pigs were examined for the presence of pathogenic Yersinia enterocolitica by enrichment procedures based on the standard method ISO 10273:2003. In addition, samples were tested by direct plating method to evaluate its efficiency compared to the enrichment culture methods and to quantify the level of contamination in porcine tonsils. In total, 52 samples (37.4%) were positive for pathogenic Y. enterocolitica, all belonging to bioserotype 4/O:3. Fifty out of the 52 positive samples (96.2%) were detected by direct plating. Enumeration showed an average concentration of 4.5 log(10) CFU g(-1) and 4.4 log(10) CFU g(-1) tonsil on Salmonella-Shigella-desoxycholate-calcium chloride (SSDC) and cefsulodin-irgasan-novobiocin (CIN) agar plates, respectively. The enrichment procedures recommended by the ISO 10273:2003 method were not optimal for the isolation of pathogenic Y. enterocolitica from pig tonsils: two days enrichment in irgasan-ticarcillin-potassium chlorate (ITC) broth resulted in an isolation rate of 84.6%, while 5 days enrichment in peptone-sorbitol-bile (PSB) broth recovered only 59.6% of positive samples. Reducing the enrichment time in PSB from 5 to 2 days resulted in a significantly higher recovery rate (94.2%) and might serve as an appropriate enrichment protocol for the isolation of pathogenic Y. enterocolitica from pig tonsils. Compared to enrichment culture methods, results based on direct plating can be obtained in a shorter time course and provide quantitative data that might be needed for further risk assessment studies.

  14. "It was like reading a detective novel": Using PAR to work together for culture change.

    Fortune, Darla; McKeown, Janet; Dupuis, Sherry; de Witt, Lorna

    2015-08-01

    Participatory action research (PAR), with its focus on engagement and collaboration, is uniquely suited to enhancing culture change initiatives in dementia care. Yet, there is limited literature of its application to culture change approaches in care settings, and even less in dementia specific care contexts. To address these gaps in the literature, the purpose of this paper is to examine the complexities of a PAR project aimed at changing the culture of dementia care in two diverse dementia care settings, including a long term care (LTC) and community care setting. Drawing from data gathered throughout the PAR process, we unpack the challenges experienced by participants working together to guide culture change within their respective care settings. These challenges include: overextending selves through culture change participation; fluctuating group membership; feeling uncertainty, confusion and apprehension about the process; frustratingly slow process; and seeking diverse group representation in decision making. We also highlight the potential for appreciative inquiry (AI) to be integrated with PAR to guide a process whereby participants involved in culture change initiatives can develop strategies to mitigate challenges they experience. We view the challenges and strategies shared here as being constructive to would-be culture change agents and hope this paper will move others to consider the use of PAR when engaging in culture change initiatives.

  17. Organizational transformation: a model for joint optimization of culture change and evidence-based design.

    Hamilton, D Kirk; Orr, Robin Diane; Raboin, W Ellen

    2008-01-01

    Healthcare organizations face continuous and accelerating external change and thus must be prepared to manage their own change initiatives proactively. Given that many believe that the U.S. healthcare system is broken and most healthcare organizations are dealing with pervasive problems, some organizations may choose to seek transformational change to achieve the six aims identified by the Institute of Medicine: healthcare that is safe, effective, patient-centered, timely, efficient, and equitable. Transformational change will almost certainly involve organizational culture. Culture change may be most effective when linked to other organizational change initiatives such as organizational strategy, structure, policies, procedures, and recruiting. Significant organizational change often requires accompanying facility change. There is an interdependent relationship between facility design and organizational culture. They affect each other and both impact organizational performance. Sociotechnical theory promotes joint optimization of the social (culture) and technical (facilities) aspects of an organization to achieve sustained positive change. To achieve organizational transformation and to sustain positive change, organizations must be prepared to adopt collaborative efforts in culture change and facility design. The authors propose a model for accomplishing joint optimization of culture change and evidence-based facility design.

  1. A 1.5 hour procedure for identification of Enterococcus Species directly from blood cultures.

    Morgan, Margie A; Marlowe, Elizabeth; Novak-Weekly, Susan; Miller, J M; Painter, T M; Salimnia, Hossein; Crystal, Benjamin

    2011-02-10

    Enterococci are a common cause of bacteremia with E. faecalis being the predominant species followed by E. faecium. Because resistance to ampicillin and vancomycin in E. faecalis is still uncommon compared to resistance in E. faecium, the development of rapid tests allowing differentiation between enterococcal species is important for appropriate therapy and resistance surveillance. The E. faecalis OE PNA FISH assay (AdvanDx, Woburn, MA) uses species-specific peptide nucleic acid (PNA) probes in a fluorescence in situ hybridization format and offers a time to results of 1.5 hours and the potential of providing important information for species-specific treatment. Multicenter studies were performed to assess the performance of the 1.5 hour E. faecalis/OE PNA FISH procedure compared to the original 2.5 hour assay procedure and to standard bacteriology methods for the identification of enterococci directly from a positive blood culture bottle.

  2. Direct Signaling from Astrocytes to Neurons in Cultures of Mammalian Brain Cells

    Nedergaard, Maiken

    1994-03-01

    Although astrocytes have been considered to be supportive, rather than transmissive, in the adult nervous system, recent studies have challenged this assumption by demonstrating that astrocytes possess functional neurotransmitter receptors. Astrocytes are now shown to directly modulate the free cytosolic calcium, and hence transmission characteristics, of neighboring neurons. When a focal electric field potential was applied to single astrocytes in mixed cultures of rat forebrain astrocytes and neurons, a prompt elevation of calcium occurred in the target cell. This in turn triggered a wave of calcium increase, which propagated from astrocyte to astrocyte. Neurons resting on these astrocytes responded with large increases in their concentration of cytosolic calcium. The gap junction blocker octanol attenuated the neuronal response, which suggests that the astrocytic-neuronal signaling is mediated through intercellular connections rather than synaptically. This neuronal response to local astrocytic stimulation may mediate local intercellular communication within the brain.

  4. AGRICULTURAL TAX SYSTEM IN POLAND AND DIRECTIONS OF THE CHANGES

    Marzena Malewska

    2014-03-01

    Full Text Available A research problem taken in the article is a question, whether legal solutions applied in the Polish system of the taxation of agriculture have an appropriate shape and whether this system is optimal? If not, what are possible options of changes and whether the in-come tax is good for agricultural activities. A method of analysis of secondary sources was used in order to solve the research problem. Required data was taken from the base of the Główny Urząd Statystyczny and scientific publications of the publishing universi-ty. In the article were formulated the following hypotheses: 1.\tThe system of the taxation of agriculture is different than other existing Polish law and it is regarded as unfair in relation to other social groups. 2.\tChanging the tax system in agriculture is necessary and would lead to positive chang-es in the structure of agriculture. 3.\tThe reform of the taxation system of agricultural production is in many aspects neces-sary and beneficial, but it should nevertheless take into account the specificities of the agricultural activity. 4.\tThe introduction of the income tax has its bad side and carries the disadvantages for both farmers and municipalities.

    Full Text Available Globalization of business has created a worldwide market where companies from around the world make interactions. National cultures have a significant influence on the way companies do business, as well as on company's market position. National culture influences the way managers interpret their environment, the types of organizational changes and employee motivation. Companies must perform more rigorous selection of workers, so as to employ a worker whose individual cultural values (that are formed under the influence of national culture correspond to organizational culture of a company, improving the competitiveness of companies in the process.

  10. Direct Measurements of Oxygen Gradients in Spheroid Culture System Using Electron Parametric Resonance Oximetry.

    Laura M Langan

    Full Text Available Advanced in vitro culture from tissues of different origin includes three-dimensional (3D organoid micro structures that may mimic conditions in vivo. One example of simple 3D culture is spheroids; ball shaped structures typically used as liver and tumour models. Oxygen is critically important in physiological processes, but is difficult to quantify in 3D culture: and the question arises, how small does a spheroid have to be to have minimal micro-environment formation? This question is of particular importance in the growing field of 3D based models for toxicological assessment. Here, we describe a simple non-invasive approach modified for the quantitative measurement and subsequent evaluation of oxygen gradients in spheroids developed from a non-malignant fish cell line (i.e. RTG-2 cells using Electron Paramagnetic Resonance (EPR oximetry. Sonication of the paramagnetic probe Lithium phthalocyanine (LiPc allows for incorporation of probe particulates into spheroid during its formation. Spectra signal strength after incorporation of probe into spheroid indicated that a volume of 20 μl of probe (stock solution: 0.10 mg/mL is sufficient to provide a strong spectra across a range of spheroid sizes. The addition of non-toxic probes (that do not produce or consume oxygen report on oxygen diffusion throughout the spheroid as a function of size. We provide evidence supporting the use of this model over a range of initial cell seeding densities and spheroid sizes with the production of oxygen distribution as a function of these parameters. In our spheroid model, lower cell seeding densities (∼2,500 cells/spheroid and absolute size (118±32 μm allow control of factors such as pre-existing stresses (e.g. ∼ 2% normoxic/hypoxic interface for more accurate measurement of treatment response. The applied methodology provides an elegant, widely applicable approach to directly characterize spheroid (and other organoid cultures in biomedical and

  12. Effects of changing canopy directional reflectance on feature selection

    Smith, J. A.; Oliver, R. E.; Kilpela, O. E.

    1973-01-01

    The use of a Monte Carlo model for generating sample directional reflectance data for two simplified target canopies at two different solar positions is reported. Successive iterations through the model permit the calculation of a mean vector and covariance matrix for canopy reflectance for varied sensor view angles. These data may then be used to calculate the divergence between the target distributions for various wavelength combinations and for these view angles. Results of a feature selection analysis indicate that different sets of wavelengths are optimum for target discrimination depending on sensor view angle and that the targets may be more easily discriminated for some scan angles than others. The time-varying behavior of these results is also pointed out.

    The material in this volume reflects the burgeoning interest in sea ducks, both as study species with compelling and unique ecological attributes and as taxa of conservation concern. In this review, we provide perspective on the current state of sea duck knowledge by highlighting key findings in the preceding chapters that are of particular value for understanding or influencing population change. We also introduce a conceptual model that characterizes links among topics covered by individual chapters and places them in the context of demographic responses. Finally, we offer recommendations for areas of future research that we suggest will have importance for understanding and managing sea duck population dynamics.

  14. A Comment on the environment and directed technical change

    Greaker, Mads; Heggedal, Tom-Reiel

    2012-07-01

    The major claim in Acemoglu, Aghion, Bursztyn and Hemous (2012) (AABH) is that subsidies for research and development of clean technologies are more important than carbon taxes when dealing with climate change. However, they – unconventionally – assume that a patent only lasts for one period. In this note we introduce long-lived patents into the AABH model. This makes the role of a research subsidy for clean technologies in AABH far less crucial and reestablishes the role of the carbon tax. This is good news as it is far easier to tax emissions than to pick the right technologies to subsidize.(Author)

  15. Lipofection of cultured mouse muscle cells: a direct comparison of Lipofectamine and DOSPER.

    Dodds, E; Dunckley, M G; Naujoks, K; Michaelis, U; Dickson, G

    1998-04-01

    Cationic lipid-DNA complexes (lipoplexes) have been widely used as gene transfer vectors which avoid the adverse immunogenicity and potential for viraemia of viral vectors. With the long-term aim of gene transfer into skeletal muscle in vivo, we describe a direct in vitro comparison of two commercially available cationic lipid formulations, Lipofectamine and DOSPER. Optimisation of transfection was performed in the C2C12 mouse muscle cell line, before further studies in primary mouse myoblasts and C2C12 myotubes. Reporter gene constructs expressing either E. coli beta-galactosidase or green fluorescent protein (GFP) were used in order to evaluate transfection efficiency by histochemical staining or FACS analysis, respectively. Both lipid formulations were able to promote efficient, reproducible gene transfer in C2C12 cells, and to transfect primary mouse myoblast cultures successfully. However, DOSPER exhibited the important advantage of being able to transfect cells in the presence of serum of both bovine and murine origin. This feature allowed increased cell survival during in vitro transfections, and may be advantageous for direct in vivo gene transfer efficacy.

    2017-01-18

    Patient mortality is significantly reduced by rapid identification of bacteria from sterile sites. MALDI-TOF can identify bacteria directly from positive blood cultures and multiple sample preparation methods are available. We evaluated three sample preparation methods and two MALDI-TOF score cut-off values. Positive blood culture bottles with organisms present in Gram stains were prospectively analysed by MALDI-TOF. Three lysis reagents (Saponin, SDS, and SepsiTyper lysis bufer) were applied to each positive culture followed by centrifugation, washing and protein extraction steps. Methods were compared using the McNemar test and 16S rDNA sequencing was used to assess discordant results. In 144 monomicrobial cultures, using ≥2.000 as the cut-off value, species level identifications were obtained from 69/144 (48%) samples using Saponin, 86/144 (60%) using SDS, and 91/144 (63%) using SepsiTyper. The difference between SDS and SepsiTyper was not statistically significant (P = 0.228). Differences between Saponin and the other two reagents were significant (P direct MALDI-TOF identification were observed in monomicrobial cultures. In 32 polymicrobial cultures, MALDI-TOF identified one organism in 34-75% of samples depending on the method. This study demonstrates two inexpensive in-house detergent lysis methods are non-inferior to a commercial kit for analysis of positive blood cultures by direct MALDI-TOF in a clinical diagnostic microbiology laboratory.

  19. Preparing culture change agents for academic medicine in a multi-institutional consortium: the C - change learning action network.

    Pololi, Linda H; Krupat, Edward; Schnell, Eugene R; Kern, David E

    2013-01-01

    Research suggests an ongoing need for change in the culture of academic medicine. This article describes the structure, activities and evaluation of a culture change project: the C - Change Learning Action Network (LAN) and its impact on participants. The LAN was developed to create the experience of a culture that would prepare participants to facilitate a culture in academic medicine that would be more collaborative, inclusive, relational, and that supports the humanity and vitality of faculty. Purposefully diverse faculty, leaders, and deans from 5 US medical schools convened in 2 1/2-day meetings biannually over 4 years. LAN meetings employed experiential, cognitive, and affective learning modes; innovative dialogue strategies; and reflective practice aimed at facilitating deep dialogue, relationship formation, collaboration, authenticity, and transformative learning to help members experience the desired culture. Robust aggregated qualitative and quantitative data collected from the 5 schools were used to inform and stimulate culture-change plans. Quantitative and qualitative evaluation methods were used. Participants indicated that a safe, supportive, inclusive, collaborative culture was established in LAN and highly valued. LAN members reported a deepened understanding of organizational change, new and valued interpersonal connections, increased motivation and resilience, new skills and approaches, increased self-awareness and personal growth, emotional connection to the issues of diversity and inclusion, and application of new learnings in their work. A carefully designed multi-institutional learning community can transform the way participants experience and view institutional culture. It can motivate and prepare them to be change agents in their own institutions.

  20. Antitumor Activity of Rat Mesenchymal Stem Cells during Direct or Indirect Co-Culturing with C6 Glioma Cells.

    Gabashvili, A N; Baklaushev, V P; Grinenko, N F; Mel'nikov, P A; Cherepanov, S A; Levinsky, A B; Chehonin, V P

    2016-02-01

    The tumor-suppressive effect of rat mesenchymal stem cells against low-differentiated rat C6 glioma cells during their direct and indirect co-culturing and during culturing of C6 glioma cells in the medium conditioned by mesenchymal stem cells was studied in an in vitro experiment. The most pronounced antitumor activity of mesenchymal stem cells was observed during direct co-culturing with C6 glioma cells. The number of live C6 glioma cells during indirect co-culturing and during culturing in conditioned medium was slightly higher than during direct co-culturing, but significantly differed from the control (C6 glioma cells cultured in medium conditioned by C6 glioma cells). The cytotoxic effect of medium conditioned by mesenchymal stem cells was not related to medium depletion by glioma cells during their growth. The medium conditioned by other "non-stem" cells (rat astrocytes and fibroblasts) produced no tumor-suppressive effect. Rat mesenchymal stem cells, similar to rat C6 glioma cells express connexin 43, the main astroglial gap junction protein. During co-culturing, mesenchymal stem cells and glioma C6 cells formed functionally active gap junctions. Gap junction blockade with connexon inhibitor carbenoxolone attenuated the antitumor effect observed during direct co-culturing of C6 glioma cells and mesenchymal stem cells to the level produced by conditioned medium. Cell-cell signaling mediated by gap junctions can be a mechanism of the tumor-suppressive effect of mesenchymal stem cells against C6 glioma cells. This phenomenon can be used for the development of new methods of cell therapy for high-grade malignant gliomas.

  1. Climate change - New directions for the Northeast: background paper

    2001-01-01

    This background paper was developed in preparation for a workshop to bring forward action options to be used for developing an action plan for the consideration of the next meeting of New England Governors/ Eastern Canadian Premiers Conference in September 2001. The background paper is the product of the cooperative effort of all eleven jurisdictions. The paper examines climate science in its global and regional aspects; climate changes impacts, identifying environmental, natural resources and infrastructure issues; monitoring of emission levels and progress in reductions; policy processes, such as leadership, cooperation, emission trading and Kyoto mechanisms; mitigation action options to reduce emissions in the Northeast context, adaptation options and their effects on the natural environment, such a coastal and forestry concerns; infrastructure development; and common Northeast issues and opportunities. A series of options in each of these areas have been identified, including gaps in options. Attention is drawn to the need to consider social and ecological objectives which will become more acute as more climate change policies and programs are implemented. 45 refs

  2. Direct numerical simulation of incompressible multiphase flow with phase change

    Lee, Moon Soo; Riaz, Amir; Aute, Vikrant

    2017-09-01

    Simulation of multiphase flow with phase change is challenging because of the potential for unphysical pressure oscillations, spurious velocity fields and mass flux errors across the interface. The resulting numerical errors may become critical when large density contrasts are present. To address these issues, we present a new approach for multiphase flow with phase change that features, (i) a smooth distribution of sharp velocity jumps and mass flux within a narrow region surrounding the interface, (ii) improved mass flux projection from the implicit interface onto the uniform Cartesian grid and (iii) post-advection velocity correction step to ensure accurate velocity divergence in interfacial cells. These new features are implemented in combination with a sharp treatment of the jumps in pressure and temperature gradient. A series of 1-D, 2-D, axisymmetric and 3-D problems are solved to verify the improvements afforded by the new approach. Axisymmetric film boiling results are also presented, which show good qualitative agreement with heat transfer correlations as well as experimental observations of bubble shapes.

    Faster identification of bacterial isolates from blood cultures can enable earlier clinical intervention for patients with sepsis. We evaluated the clinical impact of direct identification of micro-organisms from positive blood cultures using MALDI-ToF. Positive blood cultures with organisms seen on Gram stain were included over a four week period. For each patient case, comparison was made between the clinical advice given on day one with only a Gram stain result, and the follow up advice given on day two with the benefit of organism identification. Culture results were then compared with direct MALDI-ToF identification. For 73 of 115 cases (63.5%), direct organism identification was obtained by MALDI-ToF. Of those 73, 70 (95.5%) had a result concordant with that of the plate culture. In 28 of the 115 cases (24.3%) direct MALDI-ToF identification on day one would have had a clear clinical benefit. In 11 cases it would have helped to identify the potential source of bacteraemia. In 11 cases it would have indicated a different antibiotic regimen on day one, with five patients receiving appropriate antibiotics 24 hours earlier. For 14 cases the blood culture isolate could have been designated as unlikely to be clinically significant. We have demonstrated that organism identification on day one of blood culture positivity can have a direct clinical impact. Faster identification using MALDI-ToF assists the clinician in assessing the significance of a blood culture isolate on day one. It can allow earlier appropriate choice of antimicrobial agent, even in the absence of susceptibility testing, and help narrow down the potential source of infection providing a focus for further investigation in a more timely way than conventional techniques alone.

  6. Resilience and Adaptation of Cultural Heritage to Climate Change; International Workshop in Ravello (Italy) 18-19 May 2017

    Lefèvre, Roger-Alexandre

    2017-04-01

    Cultural Heritage is the core of civilization and mankind and contributes substantially to quality of life. Its preservation for its historical value and aesthetics, for its conservation and transmission, must be one of the paramount preoccupations of each citizen and institution. It is therefore fundamental to guard against a major evolution of our planet that is increasing and harmful for all the materials: climate imbalance. The tangible Cultural Heritage, often in an urban environment, is threatened both by extreme climate events, relatively short but recurrent, and by slow, insidious and continuous ones, often in relationship with pollution. The main climate factor at global scale - a general increase of mean temperatures leading to sea level rise - will have direct and indirect consequences on Cultural Heritage. The other climate threats (rain, relative humidity, solar radiation, drought, wind, floods…) and pollution (by gases and particles) will have specific effects on materials of Cultural Heritage, both outdoors (façades of monuments, historical centres of cities, open-air statues, cultural landscapes…) and indoors (museums, libraries, reserves, collections…). Since the 1st International Workshop on « Climate Change and Cultural Heritage » held at the European University Centre for Cultural Heritage in Ravello in May 2009, three important events appeared: • The publication in 2014 of the 5th IPCC Assessment Report. For the first time the Cultural Heritage was cited in an IPCC Report. • The holding in 2015 in Paris of the COP21. Some round-tables were organised during this conference concerning the Cultural Heritage. • The holding the same year in Paris of the International Scientific Conference "Our Common Future under Climate Change" in the frame and ahead of the COP21. Cultural Heritage was the topic of a special session at this important conference. During the last decade, the European scientific community was focused on the Threats and

  7. Overcoming resistance to culture change: nursing home administrators' use of education, training, and communication.

    Tyler, Denise A; Lepore, Michael; Shield, Renee R; Looze, Jessica; Miller, Susan C

    2014-01-01

    Nursing home culture change is becoming more prevalent, and research has demonstrated its benefits for nursing home residents and staff-but little is known about the role of nursing home administrators in culture change implementation. The purpose of this study was to determine what barriers nursing home administrators face in implementing culture change practices, and to identify the strategies used to overcome them. The authors conducted in-depth individual interviews with 64 administrators identified through a nationally representative survey. Results showed that a key barrier to culture change implementation reported by administrators was staff, resident, and family member resistance to change. Most nursing home administrators stressed the importance of using communication, education and training to overcome this resistance. Themes emerging around the concepts of communication and education indicate that these efforts should be ongoing, communication should be reciprocal, and that all stakeholders should be included.

    2002-01-01

    The Safety Culture Change Process Performed in research reactor MARIA is described in this paper. The essential issues fulfilled in realization of the Safety Culture Enhancement Programme are related to the attitude and behaviour of top management, co-operating groups, operational personnel, relations between the operating organization and the supervising and advising organizations. Realization of this programme is based on changing the employees understanding of safety, changing their attitudes and behaviours by means of adequate training, requalification process and performing the broad self-assessment programme. Also a high level Quality Assurance Programme helps in development of the Safety Culture. (author)

  9. Changing the Direction of Suicide Prevention in the United States.

    Reidenberg, Dan; Berman, Alan L

    2017-08-01

    It is axiomatic that the goal of suicide prevention is the prevention of suicide. Yet in spite of significant efforts to this end since the middle of the last century, and most notably in the last decade, the rate of suicide in the U.S. has not declined; rather, it has increased. To address this issue, Suicide Awareness Voices of Education (SAVE) brought together leading prevention specialists from other public health problems where successes have been achieved, representatives from countries where suicide rates have declined, and U.S. based suicide prevention researchers and program directors, to "think outside the box" and propose innovative, scalable approaches that might better drive success in achieving desired results from U.S. suicide prevention efforts. The recommendations should challenge our preconceptions and force us outside our own mental constraints to broaden our perspectives and suggest catalysts for real change in suicide prevention. © 2016 The American Association of Suicidology.

    Full Text Available Personality traits can predict how well sojourners and expatriates adjust to new cultures, but the adjustment process remains largely unexamined. Based on recent findings that reveal personality traits predict as well as respond to life events and experiences, this research focuses on within-person change in contextualized extraversion and its predictive validity for cross-cultural adjustment in international students who newly arrived in U.S. colleges. We proposed that the initial level as well as the rate of change in school extraversion (i.e., contextualized extraversion that reflects behavioral tendency in school settings will predict cross-cultural adjustment, withdrawal cognitions, and school satisfaction. Latent growth modeling of three-wave longitudinal surveys of 215 new international students (54% female, Mage = 24 years revealed that the initial level of school extraversion significantly predicted cross-cultural adjustment, (lower withdrawal cognitions, and satisfaction, while the rate of change (increase in school extraversion predicted cross-cultural adjustment and (lower withdrawal cognitions. We further modeled global extraversion and cross-cultural motivation as antecedents and explored within-person change in school extraversion as a proximal factor that affects adjustment outcomes. The findings highlight the malleability of contextualized personality, and more importantly, the importance of understanding within-person change in contextualized personality in a cross-cultural adjustment context. The study points to more research that explicate the process of personality change in other contexts.

  16. Cultural and climatic changes shape the evolutionary history of the Uralic languages.

    Honkola, T; Vesakoski, O; Korhonen, K; Lehtinen, J; Syrjänen, K; Wahlberg, N

    2013-06-01

    Quantitative phylogenetic methods have been used to study the evolutionary relationships and divergence times of biological species, and recently, these have also been applied to linguistic data to elucidate the evolutionary history of language families. In biology, the factors driving macroevolutionary processes are assumed to be either mainly biotic (the Red Queen model) or mainly abiotic (the Court Jester model) or a combination of both. The applicability of these models is assumed to depend on the temporal and spatial scale observed as biotic factors act on species divergence faster and in smaller spatial scale than the abiotic factors. Here, we used the Uralic language family to investigate whether both 'biotic' interactions (i.e. cultural interactions) and abiotic changes (i.e. climatic fluctuations) are also connected to language diversification. We estimated the times of divergence using Bayesian phylogenetics with a relaxed-clock method and related our results to climatic, historical and archaeological information. Our timing results paralleled the previous linguistic studies but suggested a later divergence of Finno-Ugric, Finnic and Saami languages. Some of the divergences co-occurred with climatic fluctuation and some with cultural interaction and migrations of populations. Thus, we suggest that both 'biotic' and abiotic factors contribute either directly or indirectly to the diversification of languages and that both models can be applied when studying language evolution. © 2013 The Authors.

  17. How to change organisational culture: Action research in a South African public sector primary care facility.

    Mash, Robert; De Sa, Angela; Christodoulou, Maria

    2016-08-31

    Organisational culture is a key factor in both patient and staff experience of the healthcare services. Patient satisfaction, staff engagement and performance are related to this experience. The department of health in the Western Cape espouses a values-based culture characterised by caring, competence, accountability, integrity, responsiveness and respect. However, transformation of the existing culture is required to achieve this vision. To explore how to transform the organisational culture in line with the desired values. Retreat Community Health Centre, Cape Town, South Africa. Participatory action research with the leadership engaged with action and reflection over a period of 18 months. Change in the organisational culture was measured at baseline and after 18 months by means of a cultural values assessment (CVA) survey. The three key leaders at the health centre also completed a 360-degree leadership values assessment (LVA) and had 6 months of coaching. Cultural entropy was reduced from 33 to 13% indicating significant transformation of organisational culture. The key driver of this transformation was change in the leadership style and functioning. Retreat health centre shifted from a culture that emphasised hierarchy, authority, command and control to one that established a greater sense of cohesion, shared vision, open communication, appreciation, respect, fairness and accountability. Transformation of organisational culture was possible through a participatory process that focused on the leadership style, communication and building relationships by means of CVA and feedback, 360-degree LVA, feedback and coaching and action learning in a co-operative inquiry group.

  19. Public Perception of Climate Change: The Importance of Knowledge and Cultural Worldviews.

    Shi, Jing; Visschers, Vivianne H M; Siegrist, Michael

    2015-12-01

    The importance of knowledge for lay people's climate change concerns has been questioned in recent years, as it had been suggested that cultural values are stronger predictors of concern about climate change than knowledge. Studies that simultaneously measured knowledge related to climate change and cultural values have, however, been missing. We conducted a mail survey in the German-speaking part of Switzerland (N = 1,065). Results suggested that cultural worldviews and climate-related knowledge were significantly related with people's concern about climate change. Also, cultural worldviews and climate-relevant knowledge appeared important for people's willingness to change behaviors and to accept climate change policies. In addition, different types of knowledge were found to have different impacts on people's concern about climate change, their willingness to change behaviors, and their acceptance of policies about climate change. Specifically, causal knowledge significantly increased concern about climate change and willingness to support climate-friendly policies. We therefore concluded that risk communication should focus on causal knowledge, provided this knowledge does not threaten cultural values. © 2015 Society for Risk Analysis.

  20. Rapid identification and susceptibility testing of Candida spp. from positive blood cultures by combination of direct MALDI-TOF mass spectrometry and direct inoculation of Vitek 2.

    2014-01-01

    Fungaemia is associated with high mortality rates and early appropriate antifungal therapy is essential for patient management. However, classical diagnostic workflow takes up to several days due to the slow growth of yeasts. Therefore, an approach for direct species identification and direct antifungal susceptibility testing (AFST) without prior time-consuming sub-culturing of yeasts from positive blood cultures (BCs) is urgently needed. Yeast cell pellets prepared using Sepsityper kit were used for direct identification by MALDI-TOF mass spectrometry (MS) and for direct inoculation of Vitek 2 AST-YS07 card for AFST. For comparison, MALDI-TOF MS and Vitek 2 testing were performed from yeast subculture. A total of twenty four positive BCs including twelve C. glabrata, nine C. albicans, two C. dubliniensis and one C. krusei isolate were processed. Applying modified thresholds for species identification (score ≥ 1.5 with two identical consecutive propositions), 62.5% of BCs were identified by direct MALDI-TOF MS. AFST results were generated for 72.7% of BCs directly tested by Vitek 2 and for 100% of standardized suspensions from 24 h cultures. Thus, AFST comparison was possible for 70 isolate-antifungal combinations. Essential agreement (minimum inhibitory concentration difference ≤ 1 double dilution step) was 88.6%. Very major errors (VMEs) (false-susceptibility), major errors (false-resistance) and minor errors (false categorization involving intermediate result) amounted to 33.3% (of resistant isolates), 1.9% (of susceptible isolates) and 1.4% providing 90.0% categorical agreement. All VMEs were due to fluconazole or voriconazole. This direct method saved on average 23.5 h for identification and 15.1 h for AFST, compared to routine procedures. However, performance for azole susceptibility testing was suboptimal and testing from subculture remains indispensable to validate the direct finding.

  2. Privatization and culture change: British Nuclear Fuels case study

    Salama, A.

    1997-01-01

    This paper describes and explains the process of organizational change experienced by British Nuclear Fuels (BNFL) during the late 1980s. BNFL went through a major transformation in management values and practices to survive in the new business environment characterized by government deregulation and fiercer global market competition. The paper describes both the historical and the prevailing management behaviour as well as the strategy utilized by BNFL's top management in their change process. The key factor in the process of change seems to lie in top management commitment and a fully integrated set of actions involving different sub-systems of the organization. (author)

    2017-01-01

    Strategies to implement evidence-based practice have highlighted the bidirectional relationship of organisational change on organisational culture. The present study examined changes in perceptions of organisational culture in two community mental health services implementing cognitive therapies into routine psychosis care over 3 years. During the time of the study there were a number of shared planned and unplanned changes that the mental health services had to accommodate. One service, Metro South, had the additional challenge of embarking on a major organisational restructure. A survey of organisational culture was administered to clinical staff of each service at yearly intervals over the 3 years. At baseline assessment there was no significant difference between the two services in organisational culture. At the midpoint assessment, which was conducted at the time the Metro South restructure was operationalized, there were less positive ratings of organisational culture recorded in Metro South compared to the other service. Organisational culture returned to near-baseline levels at endpoint assessment. These findings are consistent with the literature that organisational culture is relatively robust and resilient. It is also consistent with the literature that, at any one time, a service or organisation may have a finite capacity to absorb change. Consequently this limitation needs to be taken into account in the timing and planning of major service reform where possible. The results also extend the literature, insofar as external factors with a high impact on the operation of an organisation may impact upon organisational culture albeit temporarily.

  10. Shifting the balance of power? Culture change and identity in an English health-care setting.

    McDonald, Ruth

    2005-01-01

    A recurring theme in Government policy documents has been the need to change the culture of the NHS in order to deliver a service "fit for the twenty-first century". However, very little is said about what constitutes "culture" or how this culture change is to be brought about. This paper seeks to focus on an initiative aimed ostensibly at "empowering" staff in an English Primary Care Trust as a means of changing organisational culture. It presents findings from an ethnographic study which suggests that this attempt at "culture change" is aimed at manipulating the behaviour and values of individual employees and may be interpreted as a process of changing employee identity. Employees reacted in different ways to the empowerment initiative, with some resisting attempts to shape their identity and others actively engaging in projects to bring their unruly self into line with the ideal self to which they were encouraged to aspire. The challenges presented by the need to respond to conflicting Government policies created tensions between individuals and conflicts of allegiance and identity within individual members of staff. Alternative forms of self-hood did not merely replace existing identities, but interacted with them, often uncomfortably. The irony is that, whilst Government seeks to promote culture change, the frustrations created by its top-down target-driven regime acted to mitigate the transformational and reconstitutive effects of a discourse of empowerment aimed at achieving this change.

  11. The tragedy of Haiti: A reason for major cultural change.

    Brown, Geraldine

    2010-01-01

    With the recent earthquake in Haiti, it is most befitting to discuss my travel to this poor country more than a decade ago. The travel was a mission that examined the health status and the education of residents in the capital city of Port- au-Prince. After close observation, it seems that the health and educational status then, today and since the tragedy, is basically the same with less, if any, possible improvement. This article examines the present state of health and education of the Haitian people, in the wake of its recent tragedy. Although, the people were very poor in economics, they were rich in culture and exhibited polite mannerisms that made me feel overly welcomed in their homes and to the few resources they had to offer It appears that in past years, this country was and still is noted as the poorest country in the Americas, however, it is not the poorest country in the Western Hemisphere. On many occasions, it has been publicly and widely reported that Haiti experienced political violence throughout its history. The government of Haiti is known for corruption. It also appears that an earthquake the magnitude of 7.0 would not have easily destroyed so many of its infrastructure and people, if in the past, the surrounding countries, including the United States, would have assisted in providing this country with safer and stronger foundations for buildings and especially shelter for the residents and the many visitors who were the true victims. Despite the repressive regime, Haiti's location, history and culture were very attractive to tourists in the 1960s and 1970s. Visitors returned home with memorable artifacts that included cave paintings, wood statues (figurines) and hand made jewelry.

  17. Changing the culture of clinical education in massage therapy.

    Baskwill, Amanda

    2011-01-01

    Much within the profession of massage therapy is done according to tradition. From an epistemological viewpoint, tradition is a way of knowing or, by extension, being, that is based upon both tenacity and authority and not always in best practices. As the profession of massage therapy moves in the direction of evidence-based medicine, or evidence-informed practice, the opportunity to re-evaluate massage therapy education presents itself.

  18. Effect of changing temperature on anaerobic hydrogen production and microbial community composition in an open-mixed culture bioreactor

    Karadag, Dogan; Puhakka, Jaakko A. [Department of Chemistry and Bioengineering, Tampere University of Technology, Tampere (Finland)

    2010-10-15

    The temperature effect (37-65 C) on H{sub 2} production from glucose in an open-mixed culture bioreactor using an enrichment culture from a hot spring was studied. The dynamics of microbial communities was investigated by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). At 45 and 60 C the H{sub 2} production was the highest i.e. 1.71 and 0.85 mol H{sub 2}/mol glucose, respectively. No H{sub 2} was produced at temperatures 50 and 55 C. At 37-45 C, H{sub 2} production was produced by butyrate type fermentation while fermentation mechanism changed to ethanol type at 60 C. Clostridium species were dominant at 37-45 C while at 50-55 C and 60 C the culture was dominated by Bacillus coagulans and Thermoanaerobacterium, respectively. In the presence of B. Coagulans the metabolism was directed to lactate production. The results show that the mixed culture had two optima for H{sub 2} production and that the microbial communities and metabolic patterns promptly changed according to changing temperatures. (author)

  19. Affecting culture change and performance improvement in Medicaid nursing homes: the Promote Understanding, Leadership, and Learning (PULL) Program.

    Eliopoulos, Charlotte

    2013-01-01

    A growing number of nursing homes are implementing culture change programming to create a more homelike environment in which residents and direct care staff are empowered with greater participation in care activities. Although nursing homes that have adopted culture change practices have brought about positive transformation in their settings that have improved quality of care and life, as well as increased resident and staff satisfaction, they represent a minority of all nursing homes. Nursing homes that serve primarily a Medicaid population without supplemental sources of funding have been limited in the resources to support such change processes. The purpose of this project was to gain insight into effective strategies to provide culture change and quality improvement programming to low-performing, under-resourced nursing homes that represent the population of nursing homes least likely to have implemented this programming. Factors that interfered with transformation were identified and insights were gained into factors that need to be considered before transformational processes can be initiated. Effective educational strategies and processes that facilitate change in these types of nursing homes were identified. Despite limitations to the study, there was evidence that the experiences and findings can be of value to other low-performing, under-resourced nursing homes. Ongoing clinical work and research are needed to refine the implementation process and increase the ability to help these settings utilize resources and implement high quality cost effective care to nursing home residents.

  20. Direct identification of bacteria in positive blood culture bottles by matrix-assisted laser desorption ionisation time-of-flight mass spectrometry.

    Bernard La Scola

    Full Text Available BACKGROUND: With long delays observed between sampling and availability of results, the usefulness of blood cultures in the context of emergency infectious diseases has recently been questioned. Among methods that allow quicker bacterial identification from growing colonies, matrix-assisted laser desorption ionisation time-of-flight (MALDI-TOF mass spectrometry was demonstrated to accurately identify bacteria routinely isolated in a clinical biology laboratory. In order to speed up the identification process, in the present work we attempted bacterial identification directly from blood culture bottles detected positive by the automate. METHODOLOGY/PRINCIPAL FINDINGS: We prospectively analysed routine MALDI-TOF identification of bacteria detected in blood culture by two different protocols involving successive centrifugations and then lysis by trifluoroacetic acid or formic acid. Of the 562 blood culture broths detected as positive by the automate and containing one bacterial species, 370 (66% were correctly identified. Changing the protocol from trifluoroacetic acid to formic acid improved identification of Staphylococci, and overall correct identification increased from 59% to 76%. Lack of identification was observed mostly with viridans streptococci, and only one false positive was observed. In the 22 positive blood culture broths that contained two or more different species, only one of the species was identified in 18 samples, no species were identified in two samples and false species identifications were obtained in two cases. The positive predictive value of bacterial identification using this procedure was 99.2%. CONCLUSIONS/SIGNIFICANCE: MALDI-TOF MS is an efficient method for direct routine identification of bacterial isolates in blood culture, with the exception of polymicrobial samples and viridans streptococci. It may replace routine identification performed on colonies, provided improvement for the specificity of blood culture

  2. Metagenomic approaches for direct and cell culture evaluation of the virological quality of wastewater

    Aw, Tiong Gim; Howe, Adina; Rose, Joan B.

    2014-12-01

    Genomic-based molecular techniques are emerging as powerful tools that allow a comprehensive characterization of water and wastewater microbiomes. Most recently, next generation sequencing (NGS) technologies which produce large amounts of sequence data are beginning to impact the field of environmental virology. In this study, NGS and bioinformatics have been employed for the direct detection and characterization of viruses in wastewater and of viruses isolated after cell culture. Viral particles were concentrated and purified from sewage samples by polyethylene glycol precipitation. Viral nucleic acid was extracted and randomly amplified prior to sequencing using Illumina technology, yielding a total of 18 million sequence reads. Most of the viral sequences detected could not be characterized, indicating the great viral diversity that is yet to be discovered. This sewage virome was dominated by bacteriophages and contained sequences related to known human pathogenic viruses such as adenoviruses (species B, C and F), polyomaviruses JC and BK and enteroviruses (type B). An array of other animal viruses was also found, suggesting unknown zoonotic viruses. This study demonstrated the feasibility of metagenomic approaches to characterize viruses in complex environmental water samples.

  9. Actualizing culture change: The Promoting Excellent Alternatives in Kansas Nursing Homes (PEAK 2.0) program.

    Doll, Gayle A; Cornelison, Laci J; Rath, Heath; Syme, Maggie L

    2017-08-01

    Nursing homes have been challenged in their attempts to achieve deep, organizational change (i.e., culture change) aimed at providing quality of care and quality of life for nursing home residents through person-centered care. To attain deep change, 2 well-defined components must be in place: a shared understanding of (a) the what, or content goals, and (b) the how, or process of change. However, there are few examples of this at a macro or micro level in long-term care. In an effort to enact true culture change in nursing homes statewide, the Kansas Department for Aging and Disability Services implemented the Promoting Excellent Alternatives in Kansas Nursing Homes program. This program is a Medicaid, pay-for-performance program that formalizes the content and process of achieving culture change through person-centered care principles. This article aims to detail the content (what) and process (how) of a model macro-level program of culture change throughout the State of Kansas. Applications to the micro level (individual homes) are presented, and implications for psychologists' roles in facilitating culture change are discussed.

  12. The meaning of work and cultural psychology: Ideas for new directions

    Bendassolli, Pedro; Tateo, Luca

    2018-01-01

    Work is one arena in which human beings constitute their identities and participate in collective-cultural enterprises. But research on factors affecting the meaning of work and its outcomes focuses mostly on individual-level variables related to workers’ experience. However, scholars have recently...... proposed a shift towards a more collective dimension of meaningfulness, in particular, the cultural level. This article discusses and expands on this recent trend, demonstrating how growing attention to cultural factors of work’s meaning raises some problematic, crucial issues about the very definition...... of culture and its role in meaning-making. A particular issue is the assumption that culture is transmitted to people, that it is primarily a collective endeavour based on shared values and that culture can endow work with meaning. Based on a cultural psychology perspective, we revisit both the relationship...

  13. Is cultural change associated with eating disorders? A systematic review of the literature.

    Doris, Eli; Shekriladze, Ia; Javakhishvili, Nino; Jones, Roshan; Treasure, Janet; Tchanturia, Kate

    2015-06-01

    There is debate as to whether the development of an eating disorder (ED) may be triggered by acculturation to Western culture. While there is evidence to suggest that acculturation to Western culture is associated with risk of having an ED, these findings are limited, vary significantly, and are sometimes conflicting. To review the literature and empirical data on the association between ED symptoms and acculturation in the context of Western culture. A systematic search of peer-reviewed publications using a combination of the keywords "Culture", "Acculturation" and "Eating disorders" was first performed in August 2014 and updated in February 2015 with the following databases: PubMed and SCOPUS. Reference lists were also hand searched. In total, the search provided more than 50 studies. Following screening (as stated in the PRISMA guidelines) of the titles and abstracts by inclusion and exclusion criteria and quality assessment of the full text, 25 studies were identified to be appropriate for the review. Articles were examined in relation to the findings, as well as the ED and acculturation measures used. Eleven studies suggested considerable association between ED and culture change/acculturation. Six studies suggested little or no association between ED and culture change/acculturation. Eight studies did not primarily examine association, yet generated valuable insight. While there was relative consistency across studies in terms of the ED measures selected, measures of acculturation varied significantly. The majority of the evidence reviewed here suggests that there is a substantial association between culture change and ED psychopathology. However, both greater and lesser acculturation have been identified as risk factors for the development of an ED, and this varies depending on the group studied as well as how acculturation and culture change are conceptualized and measured. Further research is warranted to form cross-culturally acceptable definitions and

  15. Culture, science and the changing nature of fibromyalgia.

    Wolfe, Frederick; Walitt, Brian

    2013-12-01

    Fibromyalgia is a common but contested illness. Its definition and content have changed repeatedly in the 110 years of its existence. The most important change was the requirement for multiple tender points and extensive pain that arose in the 1980s, features that were not required previously. By 2010, a second shift occurred that excluded tender points, allowed less extensive pain, and placed reliance on patient-reported somatic symptoms and cognitive difficulties ('fibro fog') that had never been part of past definitions or content. Fibromyalgia is closely allied with and often indistinguishable from neurasthenia, a disorder of the late 19th and early 20th centuries that lost favour when it was perceived as being a psychological illness. Fibromyalgia's status as a 'real disease', rather than a psychocultural illness, is buttressed by social forces that include support from official criteria, patient and professional organizations, pharmaceutical companies, disability access, and the legal and academic communities.

  16. Changing the nursing culture in a special hospital.

    Dale, C; Rae, M; Tarbuck, P

    In August 1992 a damning report was published on the mental health services provided at Ashworth Special Hospital in Merseyside. It described a brutalising and damaging regime in which nurses were singled out for the strongest criticism. In November 1994 the Health Advisory Service (HAS), which has a watchdog role, spent three weeks at Ashworth reviewing developments in the wake of the inquiry report. The HAS report, published last March, praised the hospital for undergoing tremendous change and recovery. Areas of exemplary practice were evident and major dehumanising practices had been eliminated. This paper attempts to analyse some of the difficulties confronting nurses at the hospital during the years of change between the public inquiry and the HAS visit, and identifies recent major achievements and areas for further work.

    Full Text Available El presente artículo examina la relación entre los patrones de fertilidad en Estados Unidos y la inmigración hispana a dicho país considerando el impacto de la globalización económica, política y cultural en la transformación de las relaciones de pareja, la intimidad y la reproducción. Se argumenta que los patrones de fecundidad en Estados Unidos deben analizarse desde una perspectiva relacional bajo la cual se toma en cuenta la interacción entre la transformación de la fertilidad a nivel nacional en Estados Unidos y procesos globales. Para ejemplificar dicho argumento, se presenta investigación cualitativa sobre la transformación de la vida íntima de la población mexicana y de los mexicanos que residen en Estados Unidos. Dicha investigación ilustra la relación compleja que existe entre las pautas sociales y los cambios en la intimidad y la fertilidad en ambos países. Concluimos que los patrones reproductivos de la población hispana en Estados Unidos dependerán de la interacción dinámica entre los patrones de intimidad, los esquemas prevalentes sobre la familia y el tamaño familiar, y los prospectos económicos tanto en Estados Unidos como en los países latinoamericanos de origen de los diferentes grupos hispanos en Estados Unidos.

  18. Culture Matters in Successful Curriculum Change: An International Study of the Influence of National and Organizational Culture Tested With Multilevel Structural Equation Modeling.

    Jippes, Mariëlle; Driessen, Erik W; Broers, Nick J; Majoor, Gerard D; Gijselaers, Wim H; van der Vleuten, Cees P M

    2015-07-01

    National culture has been shown to play a role in curriculum change in medical schools, and business literature has described a similar influence of organizational culture on change processes in organizations. This study investigated the impact of both national and organizational culture on successful curriculum change in medical schools internationally. The authors tested a literature-based conceptual model using multilevel structural equation modeling. For the operationalization of national and organizational culture, the authors used Hofstede's dimensions of culture and Quinn and Spreitzer's competing values framework, respectively. To operationalize successful curriculum change, the authors used two derivates: medical schools' organizational readiness for curriculum change developed by Jippes and colleagues, and change-related behavior developed by Herscovitch and Meyer. The authors administered a questionnaire in 2012 measuring the described operationalizations to medical schools in the process of changing their curriculum. Nine hundred ninety-one of 1,073 invited staff members from 131 of 345 medical schools in 56 of 80 countries completed the questionnaire. An initial poor fit of the model improved to a reasonable fit by two suggested modifications which seemed theoretically plausible. In sum, characteristics of national culture and organizational culture, such as a certain level of risk taking, flexible policies and procedures, and strong leadership, affected successful curriculum change. National and organizational culture influence readiness for change in medical schools. Therefore, medical schools considering curriculum reform should anticipate the potential impact of national and organizational culture.

  19. Microbial identification and automated antibiotic susceptibility testing directly from positive blood cultures using MALDI-TOF MS and VITEK 2.

    Wattal, C; Oberoi, J K

    2016-01-01

    The study addresses the utility of Matrix Assisted Laser Desorption/Ionisation Time-Of-Flight mass spectrometry (MALDI-TOF MS) using VITEK MS and the VITEK 2 antimicrobial susceptibility testing (AST) system for direct identification (ID) and timely AST from positive blood culture bottles using a lysis-filtration method (LFM). Between July and December 2014, a total of 140 non-duplicate mono-microbial blood cultures were processed. An aliquot of positive blood culture broth was incubated with lysis buffer before the bacteria were filtered and washed. Micro-organisms recovered from the filter were first identified using VITEK MS and its suspension was used for direct AST by VITEK 2 once the ID was known. Direct ID and AST results were compared with classical methods using solid growth. Out of the 140 bottles tested, VITEK MS resulted in 70.7 % correct identification to the genus and/ or species level. For the 103 bottles where identification was possible, there was agreement in 97 samples (94.17 %) with classical culture. Compared to the routine method, the direct AST resulted in category agreement in 860 (96.5 %) of 891 bacteria-antimicrobial agent combinations tested. The results of direct ID and AST were available 16.1 hours before those of the standard approach on average. The combined use of VITEK MS and VITEK 2 directly on samples from positive blood culture bottles using a LFM technique can result in rapid and reliable ID and AST results in blood stream infections to result in early institution of targeted treatment. The combination of LFM and AST using VITEK 2 was found to expedite AST more reliably.

  20. Fluorescence In Situ Hybridization with Peptide Nucleic Acid Probes for Rapid Identification of Candida albicans Directly from Blood Culture Bottles

    Rigby, Susan; Procop, Gary W.; Haase, Gerhard; Wilson, Deborah; Hall, Geraldine; Kurtzman, Cletus; Oliveira, Kenneth; Von Oy, Sabina; Hyldig-Nielsen, Jens J.; Coull, James; Stender, Henrik

    2002-01-01

    A new fluorescence in situ hybridization (FISH) method that uses peptide nucleic acid (PNA) probes for identification of Candida albicans directly from positive-blood-culture bottles in which yeast was observed by Gram staining (herein referred to as yeast-positive blood culture bottles) is described. The test (the C. albicans PNA FISH method) is based on a fluorescein-labeled PNA probe that targets C. albicans 26S rRNA. The PNA probe is added to smears made directly from the contents of the blood culture bottle and hybridized for 90 min at 55°C. Unhybridized PNA probe is removed by washing of the mixture (30 min), and the smears are examined by fluorescence microscopy. The specificity of the method was confirmed with 23 reference strains representing phylogenetically related yeast species and 148 clinical isolates covering the clinically most significant yeast species, including C. albicans (n = 72), C. dubliniensis (n = 58), C. glabrata (n = 5), C. krusei (n = 2), C. parapsilosis (n = 4), and C. tropicalis (n = 3). The performance of the C. albicans PNA FISH method as a diagnostic test was evaluated with 33 routine and 25 simulated yeast-positive blood culture bottles and showed 100% sensitivity and 100% specificity. It is concluded that this 2.5-h method for the definitive identification of C. albicans directly from yeast-positive blood culture bottles provides important information for optimal antifungal therapy and patient management.

    Full Text Available After the introduction of the pottery tradition of La Hoguette and contemporaneous research on Earliest LBK about 10 to 15 years ago, research onthe spread of farming in Central Europe had somewhat stagnated; there were hardly any major advances in factual knowledge, nor could theoretical models be refined. In the last few years, however, an abundance of new data has appeared, partly deriving from botanical and anthropological analyses. Furthermore, newly available results from excavations in European Russia widenour understanding of the manifold and complex changes occurring during the latter 7th and 6th millennium cal BC.

  2. Selection of dairy culture and changes of Podravec cheese acidity during production

    Slavko Kirin

    2002-06-01

    Full Text Available The selection and characteristics of dairy culture play a basic role in all types of cheese production process. The most important characteristic is acidification ability i.e. lactic acid formation, which regulates manufacturing and maturing conditions of cheese, thus affecting its organoleptic characteristics as well. In this work the results on control of acidity increase in Podravec cheeseproduction are presented. In the production process, a technical culture as well as identical frozen and concentrated culture, with and without auxiliary Streptococcus thermophilus for direct milk inoculation, were used. It was established that the acidity, expressed as pH value, is more intensively developed in cheeses produced with culture for direct inoculation. This was especially evident in the first phases of production i.e. before cheese salting. During salting the acidity of cheeses, in both cases, was almoust identical. Cheeses produced with identical frozen culture and auxiliary Streptococcus thermophilus culture had more pronounced acidity before salting and lower after salting in comparison with cheeses with the mentioned two cultures. Organoleptic and other characteristics of mature cheeses were identical.

    Field sport coaches must use reliable and valid tests to assess change-of-direction speed in their athletes. Few tests feature linear sprinting with acute change- of-direction maneuvers. The Change-of-Direction and Acceleration Test (CODAT) was designed to assess field sport change-of-direction speed, and includes a linear 5-meter (m) sprint, 45° and 90° cuts, 3- m sprints to the left and right, and a linear 10-m sprint. This study analyzed the reliability and validity of this test, through comparisons to 20-m sprint (0-5, 0-10, 0-20 m intervals) and Illinois agility run (IAR) performance. Eighteen Australian footballers (age = 23.83 ± 7.04 yrs; height = 1.79 ± 0.06 m; mass = 85.36 ± 13.21 kg) were recruited. Following familiarization, subjects completed the 20-m sprint, CODAT, and IAR in 2 sessions, 48 hours apart. Intra-class correlation coefficients (ICC) assessed relative reliability. Absolute reliability was analyzed through paired samples t-tests (p ≤ 0.05) determining between-session differences. Typical error (TE), coefficient of variation (CV), and differences between the TE and smallest worthwhile change (SWC), also assessed absolute reliability and test usefulness. For the validity analysis, Pearson's correlations (p ≤ 0.05) analyzed between-test relationships. Results showed no between-session differences for any test (p = 0.19-0.86). CODAT time averaged ~6 s, and the ICC and CV equaled 0.84 and 3.0%, respectively. The homogeneous sample of Australian footballers meant that the CODAT's TE (0.19 s) exceeded the usual 0.2 x standard deviation (SD) SWC (0.10 s). However, the CODAT is capable of detecting moderate performance changes (SWC calculated as 0.5 x SD = 0.25 s). There was a near perfect correlation between the CODAT and IAR (r = 0.92), and very large correlations with the 20-m sprint (r = 0.75-0.76), suggesting that the CODAT was a valid change-of-direction speed test. Due to movement specificity, the CODAT has value for field sport

  4. Changing the culture of academic medicine: the C-Change learning action network and its impact at participating medical schools.

    Krupat, Edward; Pololi, Linda; Schnell, Eugene R; Kern, David E

    2013-09-01

    The culture of academic medicine has been described as hierarchical, competitive, and not highly supportive of female or minority faculty. In response to this, the authors designed the Learning Action Network (LAN), which was part of the National Initiative on Gender, Culture and Leadership in Medicine (C-Change). The LAN is a five-school consortium aimed at changing the organizational culture of its constituent institutions. The authors selected LAN schools to be geographically diverse and representative of U.S. medical schools. Institutional leaders and faculty representatives from constituent schools met twice yearly for four years (2006-2010), forming a cross-institutional learning community. Through their quarterly listing of institutional activities, schools reported a wide array of actions. Most common were increased faculty development and/or mentoring, new approaches to communication, and adoption of new policies and procedures. Other categories included data collection/management, engagement of key stakeholders, education regarding gender/diversity, and new/expanded leadership positions. Through exit interviews, most participants reported feeling optimistic about maintaining the momentum of change. However, some, especially in schools with leadership changes, expressed uncertainty. Participants reported that they felt that the LAN enabled, empowered, facilitated, and/or caused the reported actions.For others who might want to work toward changing the culture of academic medicine, the authors offer several lessons learned from their experiences with C-Change. Most notably, people, structures, policies, and reward systems must be put into place to support cultural values, and broad-based support should be created in order for changes to persist when inevitable transitions in leadership occur.

    In Italy family is characterized by strong ties and is based on mutual aid of all its members. In the last 20 years, the structure of families has been significantly influenced by demographic, economic and professional changes, determining a transition from a patriarchal to a nuclear family model, with a higher number of single-parent families, single-person households, childless couples, same-sex couples. However, this transition has been slower than that occurring in other countries, probably as an ongoing impact of prevalent Catholic ideology. Major demographic changes in Italian families include, 1) a decrease in the number of marriages, delays in getting married and an high number of civil ceremonies, 2) a reduced birth rate; Italy is becoming one of the European countries with lowest growth rate, and with an increasing number of births out of wedlock, 3) an increased marital instability, with a constantly growing number of legal separations. Like many countries, relatives in Italy are highly involved in the care of patients with physical and mental disorders. There are a number of psychosocial interventions used in Italy including the 'Milan Systemic Approach' and family psycho-educational interventions. However, there are difficulties in implementing these interventions which are highlighted in this paper. We recommend research strategies to identify the best options to involve families in the care of mentally ill patients and to adequately support them.

  6. The tectonic plates are shifting: cultural change vs. mural dyslexia.

    Cohn, Kenneth; Friedman, Leonard H; Allyn, Thomas R

    2007-01-01

    In response to a rapidly changing healthcare marketplace, a variety of new business models have arisen, including new specialties (hospitalists), selective care (concierge medicine), and joint ventures (ambulatory surgical centers, specialty hospitals), some with hospitals and others with independent vendors. Since both hospitals and physicians are feeling the squeeze of rising expenses, burdensome regulations, heightened consumer expectations, and stagnant or decreasing reimbursement, the response to global economic competition and the need to improve clinical and financial outcomes can bring physicians and hospitals together rather than drive them farther apart. In response to perceived threats, physicians and hospital executives can engage in defensive reasoning that may feel protective but can also lead to mural dyslexia, the inability or unwillingness to see the handwriting on the wall. The strategies of positive deviance (finding solutions that already exist in the community rather than importing best practices), appreciative inquiry (building on success rather than relying solely on root-cause analyses of problems), and structured dialogue (allowing practicing physicians to articulate clinical priorities rather than assuming they lack the maturity and will to come to consensus) are field-tested approaches that allow hospital leaders to engage practicing physicians and that can help both parties work more interdependently to improve patient care in a dynamically changing environment. Physician-hospital collaboration based on transparency, active listening, and prompt implementation can offer sustainable competitive advantage to those willing to embark on a lifetime learning journey.

  7. Social structure, infectious diseases, disasters, secularism, and cultural change in America.

    Grossmann, Igor; Varnum, Michael E W

    2015-03-01

    Why do cultures change? The present work examined cultural change in eight cultural-level markers, or correlates, of individualism in the United States, all of which increased over the course of the 20th century: frequency of individualist themes in books, preference for uniqueness in baby naming, frequency of single-child relative to multichild families, frequency of single-generation relative to multigeneration households, percentage of adults and percentage of older adults living alone, small family size, and divorce rates (relative to marriage rates). We tested five key hypotheses regarding cultural change in individualism-collectivism. As predicted by previous theories, changes in socioeconomic structure, pathogen prevalence, and secularism accompanied changes in individualism averaged across all measures. The relationship with changes in individualism was less robust for urbanization. Contrary to previous theories, changes in individualism were positively (as opposed to negatively) related to the frequency of disasters. Time-lagged analyses suggested that only socioeconomic structure had a robust effect on individualism; changes in socioeconomic structure preceded changes in individualism. Implications for anthropology, psychology, and sociology are discussed. © The Author(s) 2015.

  8. Direct delignification of untreated bark chips with mixed cultures of bacteria. [Bacillus and Cellulomonas strains

    Deschamps, A M; Gillie, J P; Lebeault, J M

    1981-01-01

    Delignification of pine bark chips was observed after about 35 days when they were the sole carbon source in mixed liquid cultures of cellulolytic and lignin degrading strains of Bacillus and Cellulomonas. No delignification was observed in pure cultures. Free tannins liberated from the chips were also degraded in most of the cultures. The necessity of combining a cellulolytic and lignin degrading bacterial strain to obtain delignification is discussed. (Refs. 25).

  9. How a more detailed understanding of culture is needed before successful educational change can be made.

    Rosenthal, Meagen; Desselle, Shane; Holmes, Erin

    2017-09-01

    The profession of pharmacy is being afforded many important opportunities, and continues to face many challenges. To successfully address these issues schools and colleges of pharmacy must have a complete understanding of their current context, which includes culture. However, little of the work on culture in pharmacy education specifically defines what these cultures are, and equally importantly how this understanding of culture can be used to make changes, improve student learning, and ultimately develop pharmacists better prepared to improve patient outcomes. Organizational culture has been defined in a multitude of ways in the literature. Martin's three-perspectives approach, which combines integrated, differentiated, and fragmented understandings, offers one way to approach defining culture and leveraging that definition of change. Furthermore, the organizational culture profile (OCP), is one tool that can be used to identify and differentiate between Martin's three perspectives. Culture plays an important role in academic pharmacy, but before it can reach its highest potential in improving student outcomes, and faculty experience, it must be completely understood. Martin's approach and the OCP offer one way to achieve this objective. Copyright © 2017 Elsevier Inc. All rights reserved.

    Compare changes in registered nurses' perception of the patient safety culture in restructured and not restructured intensive care units during a four-year period. Two cross-sectional surveys were performed, in 2008/2009 (time 1) and 2012/2013 (time 2). During a period of 0-3 years after time 1, three of six hospitals merged their general and medical intensive care units (restructured). The other hospitals maintained their structure of the intensive care units (not restructured). Intensive care units in hospitals at one Norwegian hospital trust. The safety culture was measured with Hospital Survey on Patient Safety Culture. At times 1 and 2, 217/302 (72%) and 145/289 (50%) registered nurses participated. Restructuring was negatively associated with change in the safety culture, in particular, the dimensions of the safety culture within the unit level. The dimensions most vulnerable for restructuring were manager expectations and actions promoting safety, teamwork within hospital units and staffing. In this study, the restructuring of intensive care units was associated with a negative impact on the safety culture. When restructuring, the management should be particularly aware of changes in the safety culture dimensions manager expectations and actions promoting safety, teamwork within hospital units and staffing.

  12. European Master-Doctorate Course on "Vulnerability of Cultural Heritage to Climate Change"

    Lefèvre, R.-A.

    2009-04-01

    « Vulnerability of Cultural Heritage to Climate Change », European Master-Doctorate Course, Council of Europe, Strasbourg 7-11 September 2009 The character of Cultural Heritage is closely related to the climate, and the urban landscape and the built heritage have been designed with the local climate in mind. The stability of Cultural Heritage is, therefore, closely tied to its interactions with the ground and the atmosphere. Climate Change is thus expected to have either catastrophic or subtle effects on Cultural Heritage materials and Cultural Landscapes. The major aim of the 2009 Strasbourg Course is to ensure that young European students are informed on these important problems and will be able in the future to undertake rigorous ongoing scientific monitoring of changes in conditions of Cultural Heritage. The Programme of the Course will cover the following topics: • Heritage Climatology • Principles of Mitigation and Adaptation of Cultural Heritage to Climate Change • Impact of Climate Change on building structures • Dose-Response and Damage Functions for materials in a Changing Climate • Modelling sea salts transport and deposition • Modelling wetting and drying of historic buildings • Impact of Climate Change on building materials: stone, mortar, modern glass, stained glass windows • Impact of Climate Change on organic materials • Biological impact of Climate Change on Cultural Heritage • Sea level rise models and possible application to Cultural Heritage • Past, present and future for Venice • The policies and action plans of International Organisations (Council of Europe, UNESCO, ICCROM) The Course is addressed to young people with scientific background: physicists, chemists, geologists, biologists, engineers, because of the high scientific level of the background required to follow the lectures. Teaching will be delivered in English without any simultaneous translation. The teachers belong to European Universities, National

  13. The effects of land use change and precipitation change on direct runoff in Wei River watershed, China.

    Dong, Leihua; Xiong, Lihua; Lall, Upmanu; Wang, Jiwu

    2015-01-01

    The principles and degrees to which land use change and climate change affect direct runoff generation are distinctive. In this paper, based on the MODIS data of land use in 1992 and 2003, the impacts of land use and climate change are explored using the Soil Conservation Service Curve Number (SCS-CN) method under two defined scenarios. In the first scenario, the precipitation is assumed to be constant, and thus the consequence of land use change could be evaluated. In the second scenario, the condition of land use is assumed to be constant, so the influence only induced by climate change could be assessed. Combining the conclusions of two scenarios, the effects of land use and climate change on direct runoff volume can be separated. At last, it is concluded: for the study basin, the land use types which have the greatest effect on direct runoff generation are agricultural land and water body. For the big sub basins, the effect of land use change is generally larger than that of climate change; for middle and small sub basins, most of them suffer more from land use change than from climate change.

  14. Direct effects of music in non-auditory cells in culture

    Nathalia dos Reis Lestard

    2013-01-01

    Full Text Available The biological effects of electromagnetic waves are widely studied, especially due to their harmful effects, such as radiation-induced cancer and to their application in diagnosis and therapy. However, the biological effects of sound, another physical agent to which we are frequently exposed have been considerably disregarded by the scientific community. Although a number of studies suggest that emotions evoked by music may be useful in medical care, alleviating stress and nociception in patients undergoing surgical procedures as well as in cancer and burned patients, little is known about the mechanisms by which these effects occur. It is generally accepted that the mechanosensory hair cells in the ear transduce the sound-induced mechanical vibrations into neural impulses, which are interpreted by the brain and evoke the emotional effects. In the last decade; however, several studies suggest that the response to music is even more complex. Moreover, recent evidence comes out that cell types other than auditory hair cells could response to audible sound. However, what is actually sensed by the hair cells, and possible by other cells in our organism, are physical differences in fluid pressure induced by the sound waves. Therefore, there is no reasonable impediment for any cell type of our body to respond to a pure sound or to music. Hence, the aim of the present study was to evaluate the response of a human breast cancer cell line, MCF7, to music. The results′ obtained suggest that music can alter cellular morpho-functional parameters, such as cell size and granularity in cultured cells. Moreover, our results suggest for the 1 st time that music can directly interfere with hormone binding to their targets, suggesting that music or audible sounds could modulate physiological and pathophysiological processes.

  15. Shared Cultural History as a Predictor of Political and Economic Changes among Nation States.

    Luke J Matthews

    Full Text Available Political and economic risks arise from social phenomena that spread within and across countries. Regime changes, protest movements, and stock market and default shocks can have ramifications across the globe. Quantitative models have made great strides at predicting these events in recent decades but incorporate few explicitly measured cultural variables. However, in recent years cultural evolutionary theory has emerged as a major paradigm to understand the inheritance and diffusion of human cultural variation. Here, we combine these two strands of research by proposing that measures of socio-linguistic affiliation derived from language phylogenies track variation in cultural norms that influence how political and economic changes diffuse across the globe. First, we show that changes over time in a country's democratic or autocratic character correlate with simultaneous changes among their socio-linguistic affiliations more than with changes of spatially proximate countries. Second, we find that models of changes in sovereign default status favor including socio-linguistic affiliations in addition to spatial data. These findings suggest that better measurement of cultural networks could be profoundly useful to policy makers who wish to diversify commercial, social, and other forms of investment across political and economic risks on an international scale.

  2. Culture.

    Smith, Timothy B; Rodríguez, Melanie Domenech; Bernal, Guillermo

    2011-02-01

    This article summarizes the definitions, means, and research of adapting psychotherapy to clients' cultural backgrounds. We begin by reviewing the prevailing definitions of cultural adaptation and providing a clinical example. We present an original meta-analysis of 65 experimental and quasi-experimental studies involving 8,620 participants. The omnibus effect size of d = .46 indicates that treatments specifically adapted for clients of color were moderately more effective with that clientele than traditional treatments. The most effective treatments tended to be those with greater numbers of cultural adaptations. Mental health services targeted to a specific cultural group were several times more effective than those provided to clients from a variety of cultural backgrounds. We recommend a series of research-supported therapeutic practices that account for clients' culture, with culture-specific treatments being more effective than generally culture-sensitive treatments. © 2010 Wiley Periodicals, Inc.

  3. Canadian Punjabi Sikh men's experiences of lifestyle changes following myocardial infarction: cultural connections.

    Galdas, Paul M; Oliffe, John L; Wong, Sabrina T; Ratner, Pamela A; Johnson, Joy L; Kelly, Mary T

    2012-01-01

    To describe how culture underlies Canadian Punjabi Sikh men's experiences of adopting lifestyle changes following myocardial infarction (MI). Qualitative, interpretive design. In-depth, individual interviews were conducted with 27 Canadian Punjabi Sikh men post-MI. Data were analysed using constant comparative methods. Cultural influences were identified in Punjabi Sikh men's descriptions of their experience of adopting lifestyle changes. Actions related to self-care, rehabilitation and lifestyle change post-MI were embedded in collectivist family and community contexts. Three themes, derived from the data, were found to intertwine with these contexts; they related to food consumption, physical exercise and faith and religion. These findings highlight how collectivist ideals influence Canadian Punjabi Sikh men's adoption of lifestyle changes post-MI. The content and processes by which healthcare providers deliver heart health and rehabilitation to Canadian Punjabi Sikh men might be guided, at least in part, by the collectivist cultural practices underpinning our findings.

  4. Driving and sustaining culture change in Olympic sport performance teams: a first exploration and grounded theory.

    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.

    Updegraff, Kimberly A.; Umaña-Taylor, Adriana J.; McHale, Susan M.; Wheeler, Lorey A.; Perez-Brena, Norma

    2013-01-01

    Drawing from developmental and cultural adaptation perspectives and using a longitudinal design, this study examined: (a) mean-level changes in Mexican-origin adolescents’ cultural orientations and adjustment from early to late adolescence; and (b) bidirectional associations between cultural orientations and adjustment using a cross-lag panel model. Participants included 246 Mexican-origin, predominantly immigrant families that participated in home interviews and a series of nightly phone calls when target adolescents were 12 years and 18 years of age. Girls exhibited more pronounced declines in traditional gender role attitudes than did boys, and all youth declined in familism values, time spent with family, and involvement in Mexican culture. Bidirectional relations between cultural orientations and adjustment emerged, and some associations were moderated by adolescent nativity and gender. PMID:22966929

  9. Fabrication of hydrogels with elasticity changed by alkaline phosphatase for stem cell culture.

    Toda, Hiroyuki; Yamamoto, Masaya; Uyama, Hiroshi; Tabata, Yasuhiko

    2016-01-01

    The objective of this study is to design hydrogels whose elasticity can be changed by alkaline phosphatase (ALP) in cell culture and evaluate the effect of hydrogel elasticity on an osteogenic gene expression of cells. Hydrogels were prepared by the radical polymerization of acrylamide (AAm), N,N'-methylenebisacrylamide (BIS), and Phosmer™M containing phosphate groups (PE-PAAm hydrogels). The storage modulus of PE-PAAm hydrogels prepared was changed by the preparation conditions. When human mesenchymal stem cells (hMSC) were cultured on the ALP-responsive PE-PAAm hydrogels in the presence or absence of ALP, the morphology of hMSC was observed and one of the osteogenic differentiation markers, Runx2, was evaluated. By ALP addition into the culture medium, the morphology of hMSC was changed into an elongated shape without cell damage. ALP addition modified the level of Runx2 gene expression, which was influenced by the modulus of PE-PAAm hydrogels. It is concluded that the elasticity change of hydrogel substrates in cell culture had an influence on the Runx2 gene expression of hMSC. Stem cells sense the surface elasticity of culture substrates, and their differentiation fate is biologically modified by substrate properties. Most of experiments have been performed in static conditions during cell culture, while the in vivo microenvironment is dynamically changed. In this study, we established to design an enzyme-responsive hydrogel whose elasticity can be changed by alkaline phosphatase (ALP) in cell culture to mimic in vivo conditions. As a result, the cells were deformed and the gene expression level of an osteogenic maker, Runx2, was modified by ALP treatment. This is the novel report describing to demonstrate that the dynamic alteration of hydrogel substrate elasticity could modulate the osteoblastic gene expression of human MSC in vitro.

  10. When do gamblers help themselves? Self-discontinuity increases self-directed change over time.

    Kim, Hyoun S; Wohl, Michael J A; Salmon, Melissa; Santesso, Diane

    2017-01-01

    Most disordered gamblers fail to take the necessary action to change their behavior. When action is taken, it is typically done under self-direction. Yet, little is known about what motivates gamblers to engage in self-directed change as researchers have focused almost exclusively on barriers to treatment seeking. Herein, we tested whether self-discontinuity (i.e., the notion that the self has undergone fundamental changes as a result of one's gambling) predicts self-directed change among gamblers experiencing sub-clinical levels of disordered gambling. Further, we tested whether this relationship would hold when controlling for feelings of shame and guilt about one's gambling as well as self-stigma as a disordered gambler (i.e., known barriers to change). To this end, 195 gamblers from the community completed a questionnaire battery that contained the variables of interest. Six months later, participants were re-contacted to assess whether they engaged in self-directed change. As hypothesized, the likelihood that self-directed change was attempted increased to the extent participants reported feeling self-discontinuous - an effect that remained significant when controlling for shame, guilt, and self-stigma. Results suggest that heightening the awareness that the gambling has fundamentally changed the self increases the likelihood of gamblers taking action to change their disordered gambling behaviors.

  11. Simulating the Effects of Cross-Generational Cultural Transmission on Language Change

    Gong, Tao; Shuai, Lan

    Language evolves in a socio-cultural environment. Apart from biological evolution and individual learning, cultural transmission also casts important influence on many aspects of language evolution. In this paper, based on the lexicon-syntax coevolution model, we extend the acquisition framework in our previous work to examine the roles of three forms of cultural transmission spanning the offspring, parent, and grandparent generations in language change. These transmissions are: those between the parent and offspring generations (PO), those within the offspring generation (OO), and those between the grandparent and offspring generations (GO). The simulation results of the considered model and relevant analyses illustrate not only the necessity of PO and OO transmissions for language change, thus echoing our previous findings, but also the importance of GO transmission, a form of cross-generational cultural transmission, on preserving the mutual understandability of the communal language across generations of individuals.

  12. Translucency changes of direct esthetic restorative materials after curing, aging and treatment

    Full Text Available The purpose of this article was to review the changes in translucency of direct esthetic restorative materials after curing, aging and treatment. As a criterion for the evaluation of clinical translucency changes, visual perceptibility threshold in translucency parameter difference (ΔTP of 2 was used. Translucency changes after curing were perceivable depending on experimental methods and products (largest ΔTP in resin composites = 15.9. Translucency changes after aging were reported as either relatively stable or showed perceivable changes by aging protocols (largest ΔTP in resin composites = -3.8. Translucency changes after curing, aging and treatment were perceivable in several products and experimental methods. Therefore, shade matching of direct esthetic materials should be performed considering these instabilities of translucency in direct esthetic materials.

  13. How to change organisational culture: Action research in a South African public sector primary care facility

    2016-08-01

    Full Text Available Background: Organisational culture is a key factor in both patient and staff experience of the healthcare services. Patient satisfaction, staff engagement and performance are related to this experience. The department of health in the Western Cape espouses a values-based culture characterised by caring, competence, accountability, integrity, responsiveness and respect. However, transformation of the existing culture is required to achieve this vision. Aim: To explore how to transform the organisational culture in line with the desired values. Setting: Retreat Community Health Centre, Cape Town, South Africa. Methods: Participatory action research with the leadership engaged with action and reflection over a period of 18 months. Change in the organisational culture was measured at baseline and after 18 months by means of a cultural values assessment (CVA survey. The three key leaders at the health centre also completed a 360-degree leadership values assessment (LVA and had 6 months of coaching. Results: Cultural entropy was reduced from 33 to 13% indicating significant transformation of organisational culture. The key driver of this transformation was change in the leadership style and functioning. Retreat health centre shifted from a culture that emphasised hierarchy, authority, command and control to one that established a greater sense of cohesion, shared vision, open communication, appreciation, respect, fairness and accountability. Conclusion: Transformation of organisational culture was possible through a participatory process that focused on the leadership style, communication and building relationships by means of CVA and feedback, 360-degree LVA, feedback and coaching and action learning in a co-operative inquiry group.

  14. Organizational models as configurations of structure, culture, leadership, control, and change strategy

    Janićijević Nebojša

    2017-01-01

    Full Text Available Starting from the axioms of consistency, stability, contingency, and configuration, research on organizational structure, culture, control, leadership, and change management strategy has shown that their typical configurations, or models, can be differentiated according to the same two criteria: distribution of power and dominant organizational dimension. On the one hand there are models of structure, culture, control, leadership, and change management strategy that are based on an unequal, or authoritarian, distribution of power within organizations, while on the other hand there are models that are based on democratic, or equal, distribution of power. Also, on the one hand there are models of structure, culture, control, leadership, and change strategy that are based on work structure and tasks, while on the other hand there are models of these organizational components that are based on social structure, people, and their relationships. Harmonization of typical configurations of organizational structure, culture, control, leadership, and change strategy occurs due to the harmonization of the differentiation criteria. Based on this harmonization, four organizational models have been identified as typical configurations of structure, culture, control, leadership, and change strategy: the autocratic, bureaucratic, innovative, and task models. Each of these models is effective in a different environmental contingency.

  15. CHANGING THE SAFETY CULTURE IN HANFORD TANK FARMS

    BERRIOCHOA MV; ALCALA LJ

    2009-01-06

    In 2000 the Hanford Tank Farms had one of the worst safety records in the Department of Energy Complex. By the end of FY08 the safety performance of the workforce had turned completely around, resulting in one of the best safety records in the DOE complex for operations of its kind. This paper describes the variety of programs and changes that were put in place to accomplish such a dramatic turn-around. The U.S. Department of Energy's 586-square-mile Hanford Site in Washington State was established during World War II as part of the Manhattan Project to develop nuclear materials to end the war. For the next several decades it continued to produce plutonium for the nation's defense, leaving behind vast quantities of radioactive and chemical waste. Much of this waste, 53,000,000 gallons, remains stored in 149 aging single-shell tanks and 28 newer double-shell tanks. One of the primary objectives at Hanford is to safely manage this waste until it can be prepared for disposal, but this has not always been easy. These giant underground tanks, many of which date back to the beginning of the Manhattan Project, range in size from 55,000 gallons up to 1.1 million gallons, and are buried beneath 10 feet of soil near the center of the site. Up to 67 of the older single-shell tanks have leaked as much as one million gallons into the surrounding soil. Liquids from the single-shell tanks were removed by 2003 but solids remain in the form of saltcake, sludges and a hardened heel at the bottom of some tanks. The Department of Energy's Office of River Protection was established to safely manage this waste until it could be prepared for disposal. For most of the last seven years the focus has been on safely retrieving waste from the 149 aging single-shell and moving it to the newer double-shell tanks. Removing waste from the tanks is a difficult and complex task. The tanks were made to put waste in, not take it out. Because of the toxic nature of the waste, both

    2015-06-01

    The influence of drying the culture substrate during solid-state fermentation on enzyme production was investigated using a non-airflow box. The drying caused a significant increase in enzyme production, while the mycelium content decreased slightly. This suggests that changes in the water content in the substrate during culture affect enzyme production in fungi. Copyright © 2014 The Society for Biotechnology, Japan. Published by Elsevier B.V.

  19. What characterizes the work culture at a hospital unit that successfully implements change - a correlation study.

    André, Beate; Sjøvold, Endre

    2017-07-14

    To successfully achieve change in healthcare, a balance between technology and "people ware", the human recourses, is necessary. However, the human aspect of the change implementation process has received less attention than the technological issues. The aim was to explore the factors that characterize the work culture in a hospital unit that successfully implemented change compared with the factors that characterize the work culture of a hospital unit with unsuccessful implementation. The Systematizing Person-Group Relations method was used for gathering and analyzing data to explore what dominate the behavior in a particular work environment identifying challenges, limitations and opportunities. This method applied six different dimensions, each representing different behavior in a work culture: Synergy, Withdrawal, Opposition, Dependence, Control and Nurture. We compared two different units at the same hospital, one that successfully implemented change and one that was unsuccessful. There were significant statistical differences between healthcare personnel working at a unit that successfully implemented change contrasted with the unit with unsuccessful implementation. These significant differences were found in both the synergy and control dimensions, which are important positive qualities in a work culture. The results of this study show that healthcare personnel at a unit with a successful implementation of change have a working environment with many positive qualities. This indicates that a work environment with a high focus on goal achievement and task orientation can handle the challenges of implementing changes.

  20. Change, organisational culture and the development of the South African Military Academy to 2009

    G E (Deon Visser

    2011-12-01

    Full Text Available This article investigates the impact of change and organisational culture on the growth and development of the South African Military Academy. It explores the impact of Nationalist Party rule since 1948 and black majority rule since 1994 on the institutional culture of the South African military and how that influenced the development of the Military Academy. This is intertwined with an investigation of the nature and impact of the diverging military and academic subcultures at the Academy. The article contends that, together with the historical exclusion of blacks and women from the military, the marginalisation of white English-speaking citizens by Nationalist Party rule denied the Academy the exploitation of a significant portion of the country’s human resource potential in the interest of institutional development. The same happened with the introduction of racial quotas and the marginalisation of whites since 1994. The Military Academy has, furthermore, historically been too reflective of the organisational culture of the South African National Defence Force and its predecessors instead of informing that culture to meet the challenges of military professionalism. The Academy has a potentially vital educational role to play in the South African and Sub-Saharan African militaries, but requires some changes in its organisational culture to fulfil that mission.

  1. Cultural complexity, post-colonialism and educational change: Challenges for comparative educators

    Hickling-Hudson, Anne

    2007-01-01

    This study explores various elements in the struggle for a post-colonial refashioning of cultural identity through education. Drawing on experiences in Australia and the Caribbean, the author illustrates how educational systems undergoing decolonisation reflect socio-cultural tensions of race and power. The author discusses the complexities for comparative educators in engaging with suppressed knowledge, recognising the yearnings of the marginalised, challenging the conditions that lead to poverty, and refashioning education for social justice in an era when the achievement of justice seems increasingly difficult. She argues that comparative educators can benefit from using post-colonial thinking to understand cultural complexity and promote lifeaffirming practices in educational change.

  2. Direct identification of microorganisms from positive blood cultures by MALDI-TOF MS using an in-house saponin method.

    2016-11-01

    Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a fast and reliable method for the identification of bacteria. A MALDI Sepsityper kit is generally used to prepare samples obtained directly from culture bottles. However, the relatively high cost of this kit is a major obstacle to introducing this method into routine clinical use. In this study, the accuracies of three different preparation methods for rapid direct identification of bacteria from positive blood culture bottles by MALDI-TOF MS analysis were compared. In total, 195 positive bottles were included in this study. Overall, 78.5%, 68.7%, and 76.4% of bacteria were correctly identified to the genus level (score ≥1.7) directly from positive blood cultures using the Sepsityper, centrifugation, and saponin methods, respectively. The identification rates using the Sepsityper and saponin methods were significantly higher than that using the centrifugation method (Sepsityper vs. centrifugation, pdirectly from blood culture bottles, and could be a less expensive alternative to the Sepsityper method.

  3. Volatility measurement with directional change in Chinese stock market: Statistical property and investment strategy

    Ma, Junjun; Xiong, Xiong; He, Feng; Zhang, Wei

    2017-04-01

    The stock price fluctuation is studied in this paper with intrinsic time perspective. The event, directional change (DC) or overshoot, are considered as time scale of price time series. With this directional change law, its corresponding statistical properties and parameter estimation is tested in Chinese stock market. Furthermore, a directional change trading strategy is proposed for invest in the market portfolio in Chinese stock market, and both in-sample and out-of-sample performance are compared among the different method of model parameter estimation. We conclude that DC method can capture important fluctuations in Chinese stock market and gain profit due to the statistical property that average upturn overshoot size is bigger than average downturn directional change size. The optimal parameter of DC method is not fixed and we obtained 1.8% annual excess return with this DC-based trading strategy.

  5. Changing the culture of assessment: the dominance of the summative assessment paradigm.

    2017-04-28

    Despite growing evidence of the benefits of including assessment for learning strategies within programmes of assessment, practical implementation of these approaches is often problematical. Organisational culture change is often hindered by personal and collective beliefs which encourage adherence to the existing organisational paradigm. We aimed to explore how these beliefs influenced proposals to redesign a summative assessment culture in order to improve students' use of assessment-related feedback. Using the principles of participatory design, a mixed group comprising medical students, clinical teachers and senior faculty members was challenged to develop radical solutions to improve the use of post-assessment feedback. Follow-up interviews were conducted with individual members of the group to explore their personal beliefs about the proposed redesign. Data were analysed using a socio-cultural lens. Proposed changes were dominated by a shared belief in the primacy of the summative assessment paradigm, which prevented radical redesign solutions from being accepted by group members. Participants' prior assessment experiences strongly influenced proposals for change. As participants had largely only experienced a summative assessment culture, they found it difficult to conceptualise radical change in the assessment culture. Although all group members participated, students were less successful at persuading the group to adopt their ideas. Faculty members and clinical teachers often used indirect techniques to close down discussions. The strength of individual beliefs became more apparent in the follow-up interviews. Naïve epistemologies and prior personal experiences were influential in the assessment redesign but were usually not expressed explicitly in a group setting, perhaps because of cultural conventions of politeness. In order to successfully implement a change in assessment culture, firmly-held intuitive beliefs about summative assessment will need to

    Socio-ecological systems maintain reciprocal interactions between biophysical and socioeconomic structures. As a result of these interactions key essential services for society emerge. Urban expansion is a direct driver of land change and cause serious shifts in socio-ecological relationships and the associated lifestyles. The framework of rural-urban gradients has proved to be a powerful tool for ecological research about urban influences on ecosystems and on sociological issues related to social welfare. However, to date there has not been an attempt to achieve a classification of municipalities in rural-urban gradients based on socio-ecological interactions. In this paper, we developed a methodological approach that allows identifying and classifying a set of socio-ecological network configurations in the Region of Madrid, a highly dynamic cultural landscape considered one of the European hotspots in urban development. According to their socio-ecological links, the integrated model detects four groups of municipalities, ordered along a rural-urban gradient, characterized by their degree of biophysical and socioeconomic coupling and different indicators of landscape structure and social welfare. We propose the developed model as a useful tool to improve environmental management schemes and land planning from a socio-ecological perspective, especially in territories subject to intense urban transformations and loss of rurality.

  7. The cultural evolution of democracy: saltational changes in a political regime landscape.

    Lindenfors, Patrik; Jansson, Fredrik; Sandberg, Mikael

    2011-01-01

    Transitions to democracy are most often considered the outcome of historical modernization processes. Socio-economic changes, such as increases in per capita GNP, education levels, urbanization and communication, have traditionally been found to be correlates or 'requisites' of democratic reform. However, transition times and the number of reform steps have not been studied comprehensively. Here we show that historically, transitions to democracy have mainly occurred through rapid leaps rather than slow and incremental transition steps, with a median time from autocracy to democracy of 2.4 years, and overnight in the reverse direction. Our results show that autocracy and democracy have acted as peaks in an evolutionary landscape of possible modes of institutional arrangements. Only scarcely have there been slow incremental transitions. We discuss our results in relation to the application of phylogenetic comparative methods in cultural evolution and point out that the evolving unit in this system is the institutional arrangement, not the individual country which is instead better regarded as the 'host' for the political system.

  8. Synchronous environmental and cultural change in the prehistory of the northeastern United States.

    Munoz, Samuel E; Gajewski, Konrad; Peros, Matthew C

    2010-12-21

    Climatic changes during the late Quaternary have resulted in substantial, often abrupt, rearrangements of terrestrial ecosystems, but the relationship between these environmental changes and prehistoric human culture and population size remains unclear. Using a database of archaeological radiocarbon dates alongside a network of paleoecological records (sedimentary pollen and charcoal) and paleoclimatic reconstructions, we show that periods of cultural and demographic change in the northeastern United States occurred at the same times as the major environmental-climatic transitions of that region. At 11.6, 8.2, 5.4, and 3.0 kyr BP (10(3) calendar years before present), changes in forest composition altered the distribution, availability, and predictability of food resources which triggered technological adjustments manifested in the archaeological record. Human population level has varied in response to these external changes in ecosystems, but the adoption of maize agriculture during the late Holocene also resulted in a substantial population increase. This study demonstrates the long-term interconnectedness of prehistoric human cultures and the ecosystems they inhabited, and provides a consolidated environmental-cultural framework from which more interdisciplinary research and discussion can develop. Moreover, it emphasizes the complex nature of human responses to environmental change in a temperate region.

  9. An Australian Feeling for Snow: Towards Understanding Cultural and Emotional Dimensions of Climate Change

    Andrew Gorman-Murray

    2010-03-01

    Full Text Available In Australia, snow is associated with alpine and subalpine regions in rural areas; snow is a component of ‘natural’ rather than urban environments. But the range, depth and duration of Australia’s regional snow cover is imperilled by climate change. While researchers have considered the impacts of snow retreat on the natural environment and responses from the mainland ski industry, this paper explores associated cultural and emotional dimensions of climate change. This responds to calls to account for local meanings of climate, and thus localised perceptions of and responses to climate change. Accordingly, this paper presents a case study of reactions to the affect of climate change on Tasmania’s snow country. Data is drawn from a nationwide survey of responses to the impact of climate change on Australia’s snow country, and a Tasmanian focus group. Survey respondents suggested the uneven distribution of Australia’s snow country means snow cover loss may matter more in certain areas: Tasmania was a key example cited by residents of both that state and others. Focus group respondents affirmed a connection between snow and Tasmanian cultural identity, displaying sensitivity to recent changing snow patterns. Moreover, they expressed concerns about the changes using emotive descriptions of local examples: the loss of snow cover mattered culturally and emotionally, compromising local cultural activities and meanings, and invoking affective responses. Simultaneously, respondents were ‘realistic’ about how important snow loss was, especially juxtaposed with sea level rise. Nevertheless, the impact of climate change on cultural and emotional attachments can contribute to urgent ethical, practical and political arguments about arresting global warming.

  10. Cultural change and loss of ethnoecological knowledge among the Isthmus Zapotecs of Mexico.

    Saynes-Vásquez, Alfredo; Caballero, Javier; Meave, Jorge A; Chiang, Fernando

    2013-06-11

    Global changes that affect local societies may cause the loss of ecological knowledge. The process of cultural change in Zapotec communities of the Oaxacan Isthmus intensified during the first years of the 20th century due to industrial and agro-industrial modernization projects and an increase in the level of formal schooling. Based on the case of the Oaxacan Isthmus, this study assesses the relationship between cultural change and the loss of traditional ecological knowledge (TEK). Three hundred male heads of family were interviewed from three municipalities in the Isthmus of Tehuantepec, Oaxaca, Mexico selected to span a wide range of cultural change. Each participant was shown herbarium specimens and photographs of a sample of 30 species drawn from a pool of 94 representing local plant diversity. Visual recognition of each species, knowledge of plant form, generic name, specific name, and local uses were scored. The sum of the five scores provided an index of global knowledge which we used as a proxy for TEK. Analysis of variance revealed differences between groups of economic activities. We collected socio-demographic data from the interviewees such as age, level of schooling, and competency in the local language. With these data we ran a principal component analysis and took the first axis as an index of cultural change, and correlated it with the scores obtained each respondent. We found statistically significant differences between groups of people with different economic activities, as well as a highly significant negative relationship between the Index of cultural change and ecological knowledge at all levels, with regression coefficients between 81.2% and 88.3%, indicating that cultural change is affecting traditional botanical knowledge. Our results shown that cultural change, as indicated by occupational activity, level of formal schooling, and competence in the indigenous language, is negatively associated with the loss of Zapotec ethnobotanical

    Earlier studies suggested national culture to be a potential barrier to curriculum reform in medical schools. In particular, Hofstede's cultural dimension 'uncertainty avoidance' had a significant negative relationship with the implementation rate of integrated curricula. However, some schools succeeded to adopt curriculum changes despite their country's strong uncertainty avoidance. This raised the question: 'How did those schools overcome the barrier of uncertainty avoidance?' Austria offered the combination of a high uncertainty avoidance score and integrated curricula in all its medical schools. Twenty-seven key change agents in four medical universities were interviewed and transcripts analysed using thematic cross-case analysis. Initially, strict national laws and limited autonomy of schools inhibited innovation and fostered an 'excuse culture': 'It's not our fault. It is the ministry's'. A new law increasing university autonomy stimulated reforms. However, just this law would have been insufficient as many faculty still sought to avoid change. A strong need for change, supportive and continuous leadership, and visionary change agents were also deemed essential. In societies with strong uncertainty avoidance strict legislation may enforce resistance to curriculum change. In those countries opposition by faculty can be overcome if national legislation encourages change, provided additional internal factors support the change process.

    Organisational culture is an anthropological metaphor used to inform research and consultancy and to explain organisational environments. Great emphasis has been placed during the last years on the need to change organisational culture in order to pursue effective improvement of healthcare performance. However, the precise nature of organisational culture in healthcare policy often remains underspecified and the desirability and feasibility of strategies to be adopted has been called into question. To determine the effectiveness of strategies to change organisational culture in order to improve healthcare performance.To examine the effectiveness of these strategies according to different patterns of organisational culture. We searched the following electronic databases for primary studies: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, Sociological Abstracts, Web of Knowledge, PsycINFO, Business and Management, EThOS, Index to Theses, Intute, HMIC, SIGLE, and Scopus until October 2009. The Database of Abstracts of Reviews of Effectiveness (DARE) was searched for related reviews. We also searched the reference lists of all papers and relevant reviews identified, and we contacted experts in the field for advice on further potential studies. We considered randomised controlled trials (RCTs) or well designed quasi-experimental studies, controlled clinical trials (CCTs), controlled before and after studies (CBAs) and interrupted time series analyses (ITS) meeting the quality criteria used by the Cochrane Effective Practice and Organisation of Care Group (EPOC). Studies should be set in any type of healthcare organisation in which strategies to change organisational culture in order to improve healthcare performance were applied. Our main outcomes were objective measures of professional performance and patient outcome. At least two review authors independently applied the criteria for inclusion and exclusion criteria to scan titles and

    2008-06-01

    The applicability of a new mass spectrometric technique, DART (direct analysis in real time) has been studied in the analysis of the hairy root culture of Rauvolfia serpentina. The intact hairy roots were analyzed by holding them in the gap between the DART source and the mass spectrometer for measurements. Two nitrogen-containing compounds, vomilenine and reserpine, were characterized from the analysis of the hairy roots almost instantaneously. The confirmation of the structures of the identified compounds was made through their accurate molecular formula determinations. This is the first report of the application of DART technique for the characterization of compounds that are expressed in the hairy root cultures of Rauvolfia serpentina. Moreover, this also constitutes the first report of expression of reserpine in the hairy root culture of Rauvolfia serpentina. Copyright (c) 2008 John Wiley & Sons, Ltd.

  15. Creating Innovative Frameworks to Spur Cultural Change at NASA Armstrong Flight Research Center

    2018-01-01

    Changing the culture of an organization is a monumental task that often takes years and has no set formula. Steps can be taken, however, to spur cultural change by creating spaces and infrastructure to serve as the initial driving force. An innovation space and a bicycle sharing (bike share) program were implemented at the National Aeronautics and Space Administration (NASA) Armstrong Flight Research Center (AFRC) (Edwards, California) with a vision toward connecting Center personnel, fostering collaboration and innovation, retaining newer employees, promoting flexibility, and improving the culture and workplace atmosphere. This paper discusses the steps taken, challenges faced, novel culture-change-focused design elements, lessons learned, acquired metrics, and how these initiated cultural change at AFRC. For both the innovation space and the bike share program, funding was negotiated and provided through the NASA Convergent Aeronautics Solutions (CAS) project, which was seeking to improve the innovation and collaboration capabilities at each of the four NASA aeronautics Centers. Key stakeholders across AFRC from upper management, facilities, safety, engineering, and procurement were identified early in the process and were consulted and included throughout execution to ensure that any encountered roadblocks could be easily navigated. Research was then conducted by attending conferences and visiting culture-changing organizations both inside and outside United States Government agencies. Distilling the research, identifying available space, and deciding on specific design elements for the space was conducted by a subset of individuals of diverse backgrounds to enable quick, effective decision-making. Decisions were made with the intent to increase usage and diversity of users of the space; care was taken to ensure a well-crafted atmosphere that would foster the desired culture change. The allocated physical space required major structural modifications, new

The author discusses various important and inter-related issues in the Polish societal sphere: shock therapy accompanied by the changes since the 1990's, unemployment, uncontrolled privatization, cultural trauma and cultural plaint. Theoretically, the paper belongs to anthropology of transformation, and it is based on sociological literature for the most part. The paper also discusses 'societal diagnosis', its creators, crisis in confidence as a consequence of social and cultural traumas, the weakness of political elite and criteria used to measure poverty levels. Lately, there has been a change in mythical representation about easy life in Poland related to the state' affiliation with EU. The change includes a lack of global crisis influence, resistance of the Polish society toward media influence, a rise in optimism and decrease of cultural plaint. Is this change in attitude due to cyclical alteration between phases of depression and euphoria? What will happen if depression returns? Did the Polish handle the trauma of transformation exceptionally well? Possible answers to these and other relevant questions are sought by the author in this paper, who uses, as additional sources for research, a world of local communities and individual accounts.

    Europe's cultural heritage is among the richest in the world, and draws millions of visitors to archeological sites, museums, monuments, castles, and other sites each year. The protection and conservation of European heritage is of utmost importance for our society, not only in order to preserve the European cultural identity, but also because cultural heritage is a wealth creator bringing tourism-related business opportunities on which many communities depend. However, Europe's heritage assets are extremely exposed to climate change and natural hazards, which threatens their integrity and may compromise their value. The goal of the STORM (Safeguarding Cultural Heritage through Technical and Organisational Management) project is to provide critical decision-making tools to European cultural heritage stakeholders affected by climate change and natural hazards. Here, the STORM project will be presented with a focus on climate change and natural hazard risk communication to the involved stakeholders. However, climate change communication is not a one-way process, and discussions with stakeholders are necessary to identify their specific needs. Hence, the STORM concept is tested through pilot site studies in five different countries: the Diocletian Baths in Rome, Italy; the Mellor Heritage site, Manchester, UK; the Roman Ruins of Tróia, Portugal; the Historical Centre of Rethymno on Crete, Greece and Ephesus, Izmir, Turkey. Furthermore, the past and future climatic conditions at the project's pilot sites are analysed in terms of mean state and extreme events (for example temperature and precipitation changes evident from observations and climate scenarios), which will be discussed with regard to their relevance for the local cultural heritage protection based on discussions with the stakeholders.

  1. Yeast G-proteins mediate directional sensing and polarization behaviors in response to changes in pheromone gradient direction

    Moore, Travis I.; Tanaka, Hiromasa; Kim, Hyung Joon; Jeon, Noo Li; Yi, Tau-Mu

    Yeast cells polarize by projecting up mating pheromone gradients, a classic cell polarity behavior. However, these chemical gradients may shift direction. We examine how yeast cells sense and respond to a 180o switch in the direction of microfluidically generated pheromone gradients. We identify two behaviors: at low concentrations of α-factor, the initial projection grows by bending, whereas at high concentrations, cells form a second projection toward the new source. Mutations that increase heterotrimeric G-protein activity expand the bending-growth morphology to high concentrations; mutations that increase Cdc42 activity result in second projections at low concentrations. Gradient-sensing projection bending requires interaction between Gβγ and Cdc24, whereas gradient-nonsensing projection extension is stimulated by Bem1 and hyperactivated Cdc42. Of interest, a mutation in Gα affects both bending and extension. Finally, we find a genetic perturbation that exhibits both behaviors. Overexpression of the formin Bni1, a component of the polarisome, makes both bending-growth projections and second projections at low and high α-factor concentrations, suggesting a role for Bni1 downstream of the heterotrimeric G-protein and Cdc42 during gradient sensing and response. Thus we demonstrate that G-proteins modulate in a ligand-dependent manner two fundamental cell-polarity behaviors in response to gradient directional change. PMID:23242998

  2. Rapid Identification of Staphylococcus aureus Directly from Blood Cultures by Fluorescence In Situ Hybridization with Peptide Nucleic Acid Probes

    Oliveira, Kenneth; Procop, Gary W.; Wilson, Deborah; Coull, James; Stender, Henrik

    2002-01-01

    A new fluorescence in situ hybridization (FISH) method with peptide nucleic acid (PNA) probes for identification of Staphylococcus aureus directly from positive blood culture bottles that contain gram-positive cocci in clusters (GPCC) is described. The test (the S. aureus PNA FISH assay) is based on a fluorescein-labeled PNA probe that targets a species-specific sequence of the 16S rRNA of S. aureus. Evaluations with 17 reference strains and 48 clinical isolates, including methicillin-resistant and methicillin-susceptible S. aureus species, coagulase-negative Staphylococcus species, and other clinically relevant and phylogenetically related bacteria and yeast species, showed that the assay had 100% sensitivity and 96% specificity. Clinical trials with 87 blood cultures positive for GPCC correctly identified 36 of 37 (97%) of the S. aureus-positive cultures identified by standard microbiological methods. The positive and negative predictive values were 100 and 98%, respectively. It is concluded that this rapid method (2.5 h) for identification of S. aureus directly from blood culture bottles that contain GPCC offers important information for optimal antibiotic therapy.

    2017-06-01

    Natural landscape in developing countries is facing a challenge due to economic growth, a cultural shift, and population dynamics. Farm land where is close to urban areas tending to be converted into more economically valuable spaces. Watershed Pakerisan listed as World Heritage of UNESCO, rich of cultural value on its landscape, especially the Subak, a traditional irrigation system, has a close relationship to the philosophy of Hindu-Bali culture. Nyuh Kuning, a village (local terms is Banjar) located adjacent to the Pakerisan Watershed, and has a spatial pattern in synergic ally connected with tradition, culture, and their religion. Rice field not only for economical but also its place to worship the Goddess (Dewi Sri). Rice Field in Nyuh Kuning declined significantly along past 10 years. The changing landscape of Nyuh Kuning traced through serial of aerial photographs from 2005 until 2015. Along with the broad decline of rice field, villager’s attachment on their cultural space is also changing. An economic motive pronounces a winner in the bargaining between the motives of economic value and cultural value in the Nyuh Kuning. Villagers revealed arguments that necessities nowadays prosecute high consumption, both for household and for education. Therefore conversion of rice fields to become more economical is understandable among communities. Villagers rent the rice fields to foreigners (migrants), and then foreigners take rice-fields as personal assets, not for the villagers (ritual activities and the cultural traditions) any longer. In theoritical term, villager’s emotional bond to the cultural landscape in post—productivism of rice field, is weakened. Wawedangan Desa and its complex cultural values are not part of their identity anymore. However, place dependence become the reason why the shifting place attachment is happening. Functional economic bond is mentioned as place dependence dominats in villager’s attachment. Certainly it’s not a

  4. Convergence between parent report and direct assessment of language and attention in culturally and linguistically diverse children.

    Ebert, Kerry Danahy

    2017-01-01

    Parent report is commonly used to assess language and attention in children for research and clinical purposes. It is therefore important to understand the convergent validity of parent-report tools in comparison to direct assessments of language and attention. In particular, cultural and linguistic background may influence this convergence. In this study a group of six- to eight-year old children (N = 110) completed direct assessments of language and attention and their parents reported on the same areas. Convergence between assessment types was explored using correlations. Possible influences of ethnicity (Hispanic or non-Hispanic) and of parent report language (English or Spanish) were explored using hierarchical linear regression. Correlations between parent report and direct child assessments were significant for both language and attention, suggesting convergence between assessment types. Ethnicity and parent report language did not moderate the relationships between direct child assessments and parent report tools for either attention or language.

    Ancient Silk Road played an important role in culture communication between west and east parts of the Eurasia during Bronze Age and historical period. Tens of archaic civilizations rise and fall in east parts of the Ancient Silk Road, climate change is attributed as one of the most important driving forces, while the process and mechanism for the impact of environmental change on culture evolution in the area has not been well-understood. Here we report new paleoclimate data based on multi-proxy analysis from two well-dated aeolian deposit sequences in the Hexi Corridor and Qaidam basin, where locate at the throat position of the Ancient Silk Road. Comparing with high-resolution tree rings from Qilian Mountain nearby, and archaeological evidence and historical documents, we proposed that two desertification events occurred in west Hexi Corridor between 3400-3100 BP and post 1450 AD, which induced two cultural discontinuity in that area. Climate was dry between 3400-2900 BP and wet between 2900-2000 BP in lowlands of east Qaidam basin, mismatching with the development of Nuomuhong Bronze culture in the area during 3400-2450 BP. We propose culture evolution in east Ancient Silk Road was mainly influenced by precipitation change of highlands in mountain areas,which was further influenced by large-scale vapor transport.

    Chinese tradition and culture developed from Taoism, Confucianism, and Buddhism and have influenced ethnic Chinese for thousands of years, particularly thoughts on death. Many ethnic Chinese, particularly older people, refrain from discussing death-related concerns, making it difficult to obtain advance directives, including do-not-resuscitate (DNR) directives, signed independently by older people. This study explored the attitudes of older nursing home residents in Taiwan toward signing their own DNR directives. This study adopted purposive sampling and collected data through in-depth interviews. The data were analysed using qualitative inductive content analysis, and the study location was a nursing home in Eastern Taiwan. A total of 11participants were recruited from a sample of 12 eligible participants. Most of the older residents in this study refused to make decisions independently regarding DNR directives. Content analysis of the interviews revealed four themes concerning refusing to sign DNR directives independently: not going against nature, accepting the results of cause and effect, viewing the family as a decision-making system, and practising self-effacement. Chinese cultural aspects, including Taoist, Buddhist, and Confucian philosophy, affected the autonomy of the older residents, and they relied on others to make decisions for them. Professionals must respect this family-oriented decision-making thinking of older residents because it reflects personal choice. Otherwise, healthcare providers may play a mediating role in coordinating and communicating between older residents and their families regarding EOL-care-related concerns, replacing the traditional practice of holding a family meeting.

  8. Direct identification and susceptibility testing of positive blood cultures using high speed cold centrifugation and Vitek II system.

    Bazzi, Ali M; Rabaan, Ali A; Fawarah, Mahmoud M; Al-Tawfiq, Jaffar A

    Compared to routine isolated colony-based methods, direct testing of bacterial pellets from positive blood cultures reduces turnaround time for reporting of antibiotic susceptibility. The aim of this study was to compare the accuracy, and precision, of a rapid method for direct identification and susceptibility testing of blood cultures with the routine method used in our laboratory, using Vitek 2. A total of 60 isolates were evaluated using the candidate and the routine method. The candidate method had 100% accuracy for the identification of Gram negative bacteria, Staphylococcus and Enterococcus, 50% for Streptococcus and 33.3% for Corynebacterium species. Susceptibility testing of Gram negative isolates yielded 98-100% essential agreement. For Staphylococcus and Enterococcus isolates, essential agreement was 100% for 17 antibiotics except for moxifloxacin. Direct testing of blood culture samples with Vitek 2 produced reliable identification and susceptibility results 18-24h sooner for aerobic/anaerobic facultative Gram-negative bacteria and Gram-positive Staphylococcus and Enterococcus strains.

  9. Formative assessment as a vehicle for changing classroom practice in a specific cultural context

    Chen, Jingping

    2015-09-01

    In this commentary, I interpret Xinying Yin and Gayle Ann Buck's collaborative action research from a social-cultural perspective. Classroom implementation of formative assessment is viewed as interaction between this assessment method and the local learning culture. I first identify Yin and Buck's definition of the formative assessment, and then analyze the role of formative assessment in the change of local learning culture. Based on the practice of Yin and Buck I emphasize the significance of their "bottom up" strategy to the teachers' epistemological change. I believe that this strategy may provide practicable solutions to current Chinese educational problems as well as a means for science educators to shift toward systematic professional development.

  10. The effectiveness of strategies to change organisational culture to improve healthcare performance: a systematic review.

    2011-04-03

    Organisational culture is an anthropological metaphor used to inform research and consultancy and to explain organisational environments. In recent years, increasing emphasis has been placed on the need to change organisational culture in order to improve healthcare performance. However, the precise function of organisational culture in healthcare policy often remains underspecified and the desirability and feasibility of strategies to be adopted have been called into question. The objective of this review was to determine the effectiveness of strategies to change organisational culture in order to improve healthcare performance. We searched the following electronic databases: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, Sociological Abstracts, Web of Knowledge, PsycINFO, Business and Management, EThOS, Index to Theses, Intute, HMIC, SIGLE, and Scopus until October 2009. The Database of Abstracts of Reviews of Effectiveness (DARE) was searched for related reviews. We also searched the reference lists of all papers and relevant reviews identified, and we contacted experts in the field for advice on further potential studies. We considered randomised controlled trials (RCTs) or well designed quasi-experimental studies (controlled clinical trials (CCTs), controlled before and after studies (CBAs), and interrupted time series (ITS) analyses). Studies could be set in any type of healthcare organisation in which strategies to change organisational culture in order to improve healthcare performance were applied. Our main outcomes were objective measures of professional performance and patient outcome. The search strategy yielded 4,239 records. After the full text assessment, two CBA studies were included in the review. They both assessed the impact of interventions aimed at changing organisational culture, but one evaluated the impact on work-related and personal outcomes while the other measured clinical outcomes. Both were at high risk of

  13. Minimizing cross-cultural maladaptation: How minority status facilitates change in international acculturation.

    Volpone, Sabrina D; Marquardt, Dennis J; Casper, Wendy J; Avery, Derek R

    2018-03-01

    Culturally savvy organizations recognize that selecting and developing people who can be effective in a global workforce is important in today's business environment. Nevertheless, many companies struggle to identify and develop talent who are happy and successful working and living outside their home country. We examine 1 factor that may foster success in a host country-minority status in 1's home country-as a predictor of change in acculturation over time. Specifically, we draw on the conservation of resources model to suggest that international students who have been a member of more minority groups in their home country have unique experiences working with dissimilar others that offer advantages when acculturating to new cultures and novel situations. Then, change in host country acculturation is explored as a mechanism to explain how minority status in the home country relates to intentions to leave the host country and psychological well-being 6 months after entry. Two moderators (cultural intelligence, perceived diversity climate of the host institution) of these relationships are also examined. Results revealed that the relationship between minority status in the home country and change in host country acculturation was positive and stronger for those with higher cultural intelligence. Further, the relationship between change in host country acculturation and psychological well-being was positive when perceived diversity climate of the host institution was high, but was not significant when perceived diversity climate was low.

  14. Effect of Changing Governance System: Result of Western Style Management Adoption to Japanese Culture of Ambiguity

    Kohichiro Hotta

    2009-02-01

    Full Text Available This paper considers the difficulty of management style change through observation of the management style of Company-A, one of the biggest Japanese IT companies. Japanese economy grew after World War II until the early 1990's. During that era, Ba or SECI process worked in Japanese organizations very well. Further, there was an ambiguous culture in the background of such characteristics. Some kinds of ambiguity or adhocracy made positive effects for Japanese organizational activity, or ambiguity played an important role for Ba activity. There were nested Ba's in each organization with ambiguity. Ambiguous descriptions of roles for each organizational unit activated nested Ba's and generated hot groups. After the economic crisis, Company-A changed its governance and gave clear targets for each organizational unit and for each employee. This change gave new difficulty and diminishes its competence. The change denied the ambiguity in the organization but it was the basis of the competence. Adopting a new system of governance is not a simple activity. Systems must be adjusted to the culture of the organization. Company-A should study competitors in different cultures and adjust the methodology for its culture.

  15. Culture, climate change and farm-level groundwater management: An Australian case study

    Sanderson, Matthew R.; Curtis, Allen L.

    2016-05-01

    Cultural factors - values, beliefs, and norms - provide important insights into the environmental attitudes, risk perceptions, and behaviors of the general population. Little is known, however, about the ostensibly complex relationships linking those elements of culture to climate change risk perceptions, especially in the context of farm level decision in the ground water context. This paper addresses that gap through an analysis of survey data provided by irrigators in the Namoi catchment of Australia's Murray-Darling Basin. We use Values-Beliefs-Norms theory to construct multivariate models of the relationship between ground water irrigators' interpretations of climate change risks and their implementation of adaptive water conservation practices. Results indicate that these cultural factors are important explanations of irrigators' climate change risk perceptions, and these risk perceptions are related to adaptive ground water management strategies at the farm level. The implications of the findings are discussed for research on the culture-environment nexus and for outreach designed to encourage agricultural adaptations to climate change.

  17. Reforming the Norwegian Police - Cultural Change as a Restoration of Organizational Ideologies, Myths and Practices

    Stig O. Johannessen

    2015-09-01

    Full Text Available The paper lays out the origins of the organizational culture myth and how ideas from populist movements of cultural change together with organizational control ideologies have come to be adopted as the panacea for the ills of the Norwegian Police. The paper then draws attention to how the above trends can be explored from a process theoretical perspective with a view towards organizational culture as practices emerging from patterns of communication, power, identity and moral ethics. The discussion further deconstructs changes in the mythology of official statements to demonstrate how the changes in the official values are solidifying a fantasy of sectarian unity, which at the same time threatens to collapse the functionality of the police organization. A recent example of whistleblowing demonstrates the antithesis of this development: the importance of breaking the unity in order to avoid organizational collapse and regain constructive functionality by a different understanding of leadership and moral ethics. The paper is a contribution to a broader discussion and a call for deeper knowledge of what organizational and cultural change and reform means both in the Norwegian police and other police organizations undergoing similar processes.

  7. Clonogenic growth of human breast cancer cells co-cultured in direct contact with serum-activated fibroblasts

    Samoszuk, Michael; Tan, Jenny; Chorn, Guillaume

    2005-01-01

    Accumulating evidence suggests that fibroblasts play a pivotal role in promoting the growth of breast cancer cells. The objective of the present study was to characterize and validate an in vitro model of the interaction between small numbers of human breast cancer cells and human fibroblasts. We measured the clonogenic growth of small numbers of human breast cancer cells co-cultured in direct contact with serum-activated, normal human fibroblasts. Using DNA microarrays, we also characterized the gene expression profile of the serum-activated fibroblasts. In order to validate the in vivo relevance of our experiments, we then analyzed clinical samples of metastatic breast cancer for the presence of myofibroblasts expressing α-smooth muscle actin. Clonogenic growth of human breast cancer cells obtained directly from in situ and invasive tumors was dramatically and consistently enhanced when the tumor cells were co-cultured in direct contact with serum-activated fibroblasts. This effect was abolished when the cells were co-cultured in transwells separated by permeable inserts. The fibroblasts in our experimental model exhibited a gene expression signature characteristic of 'serum response' (i.e. myofibroblasts). Immunostaining of human samples of metastatic breast cancer tissue confirmed that myofibroblasts are in direct contact with breast cancer cells. Serum-activated fibroblasts promote the clonogenic growth of human breast cancer cells in vitro through a mechanism that involves direct physical contact between the cells. This model shares many important molecular and phenotypic similarities with the fibroblasts that are naturally found in breast cancers

  9. The changing psychology of culture in German-speaking countries: A Google Ngram study.

    Younes, Nadja; Reips, Ulf-Dietrich

    2017-05-05

    This article provides evidence for the long-term affiliation between ecological and cultural changes in German-speaking countries, based on the assumptions derived from social change and human development theory. Based on this theory, the increase in urbanisation, as a measure of ecological change, is associated with significant cultural changes of psychology. Whereas urbanisation is linked to greater individualistic values and materialistic attitudes, rural environments are strongly associated with collectivistic values like allegiance, prevalence of religion, and feelings of belonging and benevolence. Due to an increase in the German urbanisation rate over time, our study investigates whether Germany and the German-speaking countries around show the presumed changes in psychology. By using Google Books Ngram Viewer, we find that word frequencies, signifying individualistic (collectivistic) values, are positively (negatively) related to the urbanisation rate of Germany. Our results indicate that predictions about implications of an urbanising population for the psychology of culture hold true, supporting international universality of the social change and human development theory. Furthermore, we provide evidence for a predicted reversal for the time during and after World War II, reflecting Nazi propaganda and influence. © 2017 International Union of Psychological Science.

  10. Natural and anthropogenic drivers of cultural change on Easter Island: Review and new insights

    Rull, Valentí

    2016-10-01

    Easter Island (Rapa Nui) is a remote Pacific island known for its megalithic statues, the moai, built by an ancient culture which disappearance is still debated. Theories claiming for either self-destruction (ecocide) of this ancient culture or an eventual genocide after the European contact have been the most popular. Anthropogenic drivers have been traditionally preferred as causes of this major cultural shift, whereas climatic changes have been dismissed or underrated. However, the latest findings suggest that the topic is more complex than formerly thought and demand a more holistic perspective. This paper reviews the main paleoclimatic, paleoecological, archaeological and historical evidence of the major Rapanui cultural shift leading to the end of the moai-building civilization and uses an integrated approach to analyze its timing and potential causes. The disappearance of the ancient Eastern Island culture that erected the moai was a dramatic cultural shift with significant changes in lifestyle, socio-political organization, religious performance, art and also in the geographical settlement of the cultural core of the Rapanui society. The ancient society, represented by the so called Ancient Cult (or moai cult) was centered on the Rano Raraku crater, to the east of the island, whose soft volcanic rocks (tuff) where suitable for moai carving. This society was replaced by the Birdman-Cult society, based on Rano Kao, to the westernmost end of the island. The assumed date for such shift is uncertain ranging between mid-16th and late-18th centuries. It is suggested that such geographical change, as well as the associated societal transformations, may have been the result of a combination of climatic, ecological and cultural drivers and events. The latest paleoecological reconstructions show that the Rano Raraku catchment was deforested by AD 1450 and the lake inside dried out by AD 1550 owing to an intense climatic drought. This would have caused a landscape

    Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) allows a fast and reliable bacterial identification from culture plates. Direct analysis of clinical samples may increase its usefulness in samples in which a fast identification of microorganisms can guide empirical treatment, such as blood cultures (BC). Three hundred and thirty BC, reported as positive by the automated BC incubation device, were processed by conventional methods for BC processing, and by a fast method based on direct MALDI-TOF MS. Three hundred and eighteen of them yield growth on culture plates, and 12 were false positive. The MALDI-TOF MS-based method reported that no peaks were found, or the absence of a reliable identification profile, in all these false positive BC. No mixed cultures were found. Among these 318 BC, we isolated 61 Gram-negatives (GN), 239 Gram-positives (GP) and 18 fungi. Microorganism identifications in GN were coincident with conventional identification, at the species level, in 83.3% of BC and, at the genus level, in 96.6%. In GP, identifications were coincident with conventional identification in 31.8% of BC at the species level, and in 64.8% at the genus level. Fungaemia was not reliably detected by MALDI-TOF. In 18 BC positive for Candida species (eight C. albicans, nine C. parapsilosis and one C. tropicalis), no microorganisms were identified at the species level, and only one (5.6%) was detected at the genus level. The results of the present study show that this fast, MALDI-TOF MS-based method allows bacterial identification directly from presumptively positive BC in a short time (<30 min), with a high accuracy, especially when GN bacteria are involved. © 2010 The Authors.

    Full Text Available The aim of the present study was to examine the reliability of a novel multi-direction repeated sprint ability test (RSM; 10×(6×5-m compared with a repeated sprint ability test (RSA with one change of direction (10×(2×15-m, and the relationship of the RSM and RSA with Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1 and jump performances [squat jump (SJ and counter-movement-jump (CMJ]. Thirty-six (male, n=14, female n=22 young basketball players (age 16.0±0.9 yrs performed the RSM, RSA, Yo-Yo IR1, SJ and CMJ, and were re-tested only for RSM and RSA after one week. The absolute error of reliability (standard error of the measurement was lower than 0.212-s and 0.617-s for the time variables of the RSA and RSM test, respectively. Performance in the RSA and RSM test significantly correlated with CMJ and SJ. The best time, worst time and total time of the RSA and RSM test were negatively correlated with Yo-Yo IR1 distance. Based on these findings, consistent with previously published studies, it was concluded that the novel RSM test was valid and reliable.

    2001-01-01

    Enrichment cultures of microbial consortia enable the diverse metabolic and catabolic activities of these populations to be studied on a molecular level and to be explored as potential sources for biotechnology processes. We have used a combined approach of enrichment culture and direct cloning to construct cosmid libraries with large (>30-kb) inserts from microbial consortia. Enrichment cultures were inoculated with samples from five environments, and high amounts of avidin were added to the cultures to favor growth of biotin-producing microbes. DNA was extracted from three of these enrichment cultures and used to construct cosmid libraries; each library consisted of between 6,000 and 35,000 clones, with an average insert size of 30 to 40 kb. The inserts contained a diverse population of genomic DNA fragments isolated from the consortia organisms. These three libraries were used to complement the Escherichia coli biotin auxotrophic strain ATCC 33767 Delta(bio-uvrB). Initial screens resulted in the isolation of seven different complementing cosmid clones, carrying biotin biosynthesis operons. Biotin biosynthesis capabilities and growth under defined conditions of four of these clones were studied. Biotin measured in the different culture supernatants ranged from 42 to 3,800 pg/ml/optical density unit. Sequencing the identified biotin synthesis genes revealed high similarities to bio operons from gram-negative bacteria. In addition, random sequencing identified other interesting open reading frames, as well as two operons, the histidine utilization operon (hut), and the cluster of genes involved in biosynthesis of molybdopterin cofactors in bacteria (moaABCDE).

    1985-09-01

    Of the many aspects of aesthetic surgery, the double-eyelid operation generates the most interest for Japanese surgeons, as there has been an enormous demand for it by patients who are fashion-conscious. It has been possible to locate 32 operative procedures that have been published in the Japanese literature over the past ninety years. Some of these procedures have been reviewed here in relation to the cultural and social changes which are important factors determining the extent of the demand for the operation and which correlate with various changes in surgical technique. This study chronologically describes each of the principal methods related to these social changes and also considers the influence of cultural fads and fashions.

    Liu Qianfeng; Bo Hanliang; Qin Benke

    2009-01-01

    Control rod hydraulic drive mechanism(CRHDM) is a newly invented patent of Institute of Nuclear and New Energy Technology of Tsinghua University. The direct action solenoid valve is the key part of this technology, so the performance of the solenoid valve directly affects the function of the CRHDM. With the current and the air gap changing,the electromagnetic field of the direct action solenoid valve was analyzed using the ANSYS software,which was validated by the experiment. The result shows that the electromagnetic force of the solenoid valve increases with the current increasing or the gap between the two armatures decreasing. Further more, the working current was confirmed. (authors)

    Climate change is one of the main factors with a significant impact on changes of cultural heritage and landscapes. Exposed and buried archaeological remains are particularly endangered by effects of climate change processes hence it is of great importance to understand the type of risks and the degree of their impact on such assets. Some of the potential risks for cultural heritage and landscape include flooding, intense rainfall, increase in time of wetness, extreme events in temperature change, coastal flooding, drought, wind driven/transported agents (sand, rain or salt) and so forth. From the geo-science perspective, the topic of climate change and the risks it causes is of crucial importance for environmental monitoring in general and it is one of the main applications of the European program on Earth Observation Copernicus. The activities performed in CLIMA project - "Cultural Landscape risk Identification, Management and Assessment" have as one of the main tasks to combining the fields of remote sensing technologies, including the Sentinel data, and cultural heritage monitoring. Such interdisciplinary approach was undertaken in order to identify major climate change risks affecting archaeological heritage in rural areas in Cyprus and to identify the most suitable Earth Observation (EO) and ground-based methods that might be effective in the mapping, diagnostics and monitoring of such risks. This thorough analysis will support the overall design of the CLIMA platform based in EO data analysis, risk models and ground-based methods to provide integrated information for specialists in remote sensing but also to archeologists and policy makers engaged in heritage preservation and management. The case study selected for Cyprus is the awarded Nea Paphos archeological site and historical center of Paphos that is surrounding this UNSECO World Heritage site.

  17. Direct Succinic Acid Production from Minimally Pretreated Biomass Using Sequential Solid-State and Slurry Fermentation with Mixed Fungal Cultures

    Jerico Alcantara

    2017-06-01

    Full Text Available Conventional bio-based succinic acid production involves anaerobic bacterial fermentation of pure sugars. This study explored a new route for directly producing succinic acid from minimally-pretreated lignocellulosic biomass via a consolidated bioprocessing technology employing a mixed lignocellulolytic and acidogenic fungal co-culture. The process involved a solid-state pre-fermentation stage followed by a two-phase slurry fermentation stage. During the solid-state pre-fermentation stage, Aspergillus niger and Trichoderma reesei were co-cultured in a nitrogen-rich substrate (e.g., soybean hull to induce cellulolytic enzyme activity. The ligninolytic fungus Phanerochaete chrysosporium was grown separately on carbon-rich birch wood chips to induce ligninolytic enzymes, rendering the biomass more susceptible to cellulase attack. The solid-state pre-cultures were then combined in a slurry fermentation culture to achieve simultaneous enzymatic cellulolysis and succinic acid production. This approach generated succinic acid at maximum titers of 32.43 g/L after 72 h of batch slurry fermentation (~10 g/L production, and 61.12 g/L after 36 h of addition of fresh birch wood chips at the onset of the slurry fermentation stage (~26 g/L production. Based on this result, this approach is a promising alternative to current bacterial succinic acid production due to its minimal substrate pretreatment requirements, which could reduce production costs.

    Bebbington, P; Ghubash, R; Hamdi, E

    1993-04-01

    The Dubai Community Psychiatric Survey was carried out to assess the effect of very rapid social change on the mental health of women in Dubai, one of the United Arab Emirates. In order to measure social change at an individual level, we developed a questionnaire covering behaviour and attitudes in a wide range of situations, the Socio-cultural Change Questionnaire (ScCQ). In this paper we give an account of the considerations that determined the form of the ScCQ, its structural characteristics, and its validity.

  1. Changes in direct and indirect taxation in the process of the EU tax system reform

    Miletić Vesna

    2015-01-01

    Full Text Available Proceeding from the changes in direct and indirect taxation in the process of the EU tax system reform and the fact that new trends bring about vital social changes, the research in this area could add to the understanding of economic development of these countries. In the EU with its decentralized tax policy, changes in direct and indirect taxation are permanently implemented in the process of tax system reform. Harmonization of direct and indirect taxation in the EU is conducted by means of the adopted community law regulations. In the harmonization of direct taxation there is a tendency towards an increase of the level of fiscal coordination and elimination of barriers to the common market. Thus direct taxation reforms are limited to achieving higher level of coordination and preventing evasion and double taxation. The current policy is the result of the principle according to which fiscal competition has positive effects on reducing consumption and on the EU economic development. In the harmonization process the systems of indirect taxation are aligned particularly with excise duty and value added tax. Fiscal strategies in the reform process are mostly aimed at fiscal coordination, modernization, informative cooperation, evasion reduction and elimination of malpractices in fulfilling a VAT payment liability. Within the excise tax system minimal excise rates are determined and an environmentally-friendly policy is pursued. The main priorities of taxation changes within the harmonization process are in respect of evasion reduction and irrational fiscal competition on the EU market. A study of direct and indirect taxation changes in the process of the tax system reform is highly significant both from the aspect of efficient tax-system functioning, which results in achieving EU macroeconomic goals, and from the aspect of single states' interests in the process of transition and accession.

  2. Embedding security messages in existing processes: a pragmatic and effective approach to information security culture change

    Lopienski, Sebastian

    Companies and organizations world-wide depend more and more on IT infrastructure and operations. Computer systems store vital information and sensitive data; computing services are essential for main business processes. This high dependency comes with a number of security risks, which have to be managed correctly on technological, organizational and human levels. Addressing the human aspects of information security often boils down just to procedures, training and awareness raising. On the other hand, employees and collaborators do not adopt security attitude and habits simply when told to do so – a real change in behaviour requires an established security culture. But how to introduce a security culture? This thesis outlines the need of developing or improving security culture, and discusses how this can be done. The proposed approach is to gradually build security knowledge and awareness, and influence behaviours. The way to achieve this is to make security communication pervasive by embedding security me...

  3. National Culture and Business Model Change - A Framework for Successful Expansions

    Stenskov, Lea Houmark; Lueg, Rainer

    2014-01-01

    This paper proposes a conceptual framework to analyse how a company’s business model needs to be adjusted if it is expanded into another cultural context. For this, we use the example of changes in the business model of a Danish ITcompany opening a new office in the U.S. Using a single case study......, we integrate the concepts of business models (Osterwalder and Pigneur, 2005) and national culture (Hofstede, 1980). Our findings explain why and how adjustments in the business model are necessary regarding the company’s communication, team composition, and customer involvement in projects....... As to implications, we construct a matrix combining business models and national culture that other multinational companies can use to achieve better understanding of their business model in different national contexts....

  4. Managing culture change in the commercial nuclear industry and the DOE weapons complex

    Buhl, A.R.

    1992-01-01

    Culture is the basic pattern of shared beliefs, behaviors, and assumptions acquired over time by the people in the organization. Culture is learned and can be modified over time. Many failures in managing change in recent years in the commercial nuclear industry and in the DOE weapons complex can be attributed to not accepting the central axiom of safety, health, and environmental matters. This paper presents specific lessons learned from experiences in commercial nuclear power and US Department of Energy weapons facilities restarts: (1) the attributes of problem plants and symptoms that predict impending regulatory doom; (2) the root causes of plant shutdown by regulators; (3) management infrastructure problems; and (4) actions required by management to effect the culture shift necessary to resume operations

  5. Cultural Differences in Spatial Composition and Visual Directionality: A Comparative study of English and Chinese Newspaper Advertisements

    Yanli MENG

    2013-07-01

    Full Text Available This paper aims to demonstrate the notion that visual communication is not an unbiased, universally perceived means of communication. Instead, it is even more culturally loaded than verbal language in that it operates very often at the unconscious level of mind and thus often escapes from critical analysis. This paper draws on Kress and van Leeuwen’s (1996 framework of visual grammar, especially the two descriptive categories under visual composition -- spatial arrangement and visual directionality, to analyze several subscription advertisements of several Chinese and English newspapers. It is found that these advertisements display very different features in visual communication which can only be satisfactorily explained with consideration of a complex array of underlying factors including traditions of visual culture, writing system, philosophy, etc.

  6. Relationship between strength, power, speed, and change of direction performance of female softball players.

    2010-04-01

    The purpose of this study was to investigate (a) the cross-sectional relationship of strength, power, and performance variables in trained female athletes and (b) determine if the relationship between these variables changes over the course of a season. Ten female softball players (age = 18.1 +/- 1.6 years, height = 166.5 +/- 8.9 cm, and weight = 72.4 +/- 10.8 kg) from a state Australian Institute of Sport softball team were tested for maximal lower body strength (one repetition maximum [1RM]), peak force (PF), peak velocity (PV), and peak power (PP) during jump squats unloaded and loaded, unloaded countermovement vertical jump height (VJH) 1 base and 2 base sprint performance and change of direction performance on dominant and nondominant sides. The testing sessions occurred pre, mid, and post a 20-week training period. Relationship between body weight (BW), relative strength (1RM/BW), VJH, relative PP, relative PF, PV, speed, and change of direction variables were assessed by Pearson product-moment correlation coefficient at each testing session. Significant relationships were found across all time points with BW, speed, and change of direction measures (r = 0.70-0.93) and relative strength and measures of speed and change of direction ability (r = -0.73-0.85). There were no significant relationships between VJH and any measure of performance at any time point. In conclusion, BW and relative strength have strong to very strong correlations with speed and change of direction ability, and these correlations remain consistent over the course of the season. However, it seems as if many relationships vary with time, and their relationships should therefore be investigated longitudinally to better determine if these cross-sectional relationships truly reflect a deterministic relationship.

  7. Directionality of recent bird distribution shifts and climate change in Great Britain.

    Gillings, Simon; Balmer, Dawn E; Fuller, Robert J

    2015-06-01

    There is good evidence that species' distributions are shifting poleward in response to climate change and wide interest in the magnitude of such responses for scientific and conservation purposes. It has been suggested from the directions of climatic changes that species' distribution shifts may not be simply poleward, but this has been rarely tested with observed data. Here, we apply a novel approach to measuring range shifts on axes ranging through 360°, to recent data on the distributions of 122 species of British breeding birds during 1988-1991 and 2008-2011. Although previously documented poleward range shifts have continued, with an average 13.5 km shift northward, our analysis indicates this is an underestimate because it ignores common and larger shifts that occurred along axes oriented to the north-west and north-east. Trailing edges contracted from a broad range of southerly directions. Importantly, these results are derived from systematically collected data so confounding observer-effort biases can be discounted. Analyses of climate for the same period show that whilst temperature trends should drive species along a north-north-westerly trajectory, directional responses to precipitation will depend on both the time of year that is important for determining a species' distribution, and the location of the range margin. Directions of species' range centroid shift were not correlated with spatial trends in any single climate variable. We conclude that range shifts of British birds are multidirectional, individualistic and probably determined by species-specific interactions of multiple climate factors. Climate change is predicted to lead to changes in community composition through variation in the rates that species' ranges shift; our results suggest communities could change further owing to constituent species shifting along different trajectories. We recommend more studies consider directionality in climate and range dynamics to produce more

    2010-06-01

    Clinical error in acute care hospitals can only be addressed by developing a culture of safety. We sought to develop a cultural assessment survey (CAS) to assess patient safety culture change in obstetrical units. Interview prompts and a preliminary questionnaire were developed through a literature review of patient safety and "high reliability organizations," followed by interviews with members of the Managing Obstetrical Risk Efficiently (MOREOB) Program of the Society of Obstetricians and Gynaecologists of Canada. Three hundred preliminary questionnaires were mailed, and 21 interviews and 9 focus groups were conducted with the staff of 11 hospital sites participating in the program. To pilot test the CAS, 350 surveys were mailed to staff in participating hospitals, and interviews were conducted with seven nurses and five physicians who had completed the survey. Reliability analysis was conducted on four units that completed the CAS prior to and following the implementation of the first MOREOB module. Nineteen values and 105 behaviours, practices, and perceptions relating to patient safety were identified and included in the preliminary questionnaire, of which 143 of 300 (47.4%) were returned. Among the 220 cultural assessment surveys returned (62.9%), six cultural scales emerged: (1) patient safety as everyone's priority; (2) teamwork; (3) valuing individuals; (4) open communication; (5) learning; and (6) empowering individuals. The reliability analysis found all six scales to have internal reliability (Cronbach alpha), ranging from 0.72 (open communication) to 0.84 (valuing individuals). The CAS developed for this study may enable obstetrical units to assess change in patient safety culture.

  9. Climate change and protection: Recent experiences within planning of the area of cultural and natural heritage

    Crnčević Tijana

    2015-01-01

    Full Text Available The aim of the paper is to provide an insight into the current legal and other regulatory frameworks that introduces problems of climate change into planning practice of natural and cultural heritage, with special emphasis on the situation in the Republic of Serbia. Further, an overview of the selected case studies of natural and cultural heritage from the UNESCO World Heritage List for which were done studies of the impacts of climate change is included. The results indicate that the legal frameworks as well as actual practice are promoting the development of the ecological networks (the network of areas NATURA 2000 and landscape protection. This applies also to the planning practice in Serbia, where the planning of ecological corridors, habitat networking and other measures, provide responses to climate change. One of the conclusions of this paper is pointing out the necessity of increasing the level of protection of natural and cultural heritage within preserving the authenticity and improving flexibility or adaptability to climate change.

    The application of low-intensity direct current electric fields has been experimentally used in the clinic to treat a number of brain disorders, predominantly using transcranial direct current stimulation approaches. However, the cellular and molecular changes induced by such treatment remain largely unknown. Here, we tested various intensities of direct current electric fields (0, 25, 50, and 100V/m) in a well-controlled in vitro environment in order to investigate the responses of neurons, microglia, and astrocytes to this type of stimulation. This included morphological assessments of the cells, viability, as well as shape and fiber outgrowth relative to the orientation of the direct current electric field. We also undertook enzyme-linked immunosorbent assays and western immunoblotting to identify which molecular pathways were affected by direct current electric fields. In response to direct current electric field, neurons developed an elongated cell body shape with neurite outgrowth that was associated with a significant increase in growth associated protein-43. Fetal midbrain dopaminergic explants grown in a collagen gel matrix also showed a reorientation of their neurites towards the cathode. BV2 microglial cells adopted distinct morphological changes with an increase in cyclooxygenase-2 expression, but these were dependent on whether they had already been activated with lipopolysaccharide. Finally, astrocytes displayed elongated cell bodies with cellular filopodia that were oriented perpendicularly to the direct current electric field. We show that cells of the central nervous system can respond to direct current electric fields both in terms of their morphological shape and molecular expression of certain proteins, and this in turn can help us to begin understand the mechanisms underlying the clinical benefits of direct current electric field. © The Author 2015.

  11. Ultrastructural changes in biofilm forms of staphylococci cultivated in a mixed culture with lactobacilli

    G. Lavryk

    2017-02-01

    Full Text Available The capacity of opportunistic bacteria for biofilm formation plays an important role in the development of chronic inflammatory processes, which are difficult to treat. To improve antimicrobial therapy methods, the influence of lactobacilli on the ultrastructure of biofilm-forming clinical strains of staphylococci when co-cultured was investigated. 5 biofilm-forming clinical strains of S. aureus from the skin of acne vulgaris patients (n = 24 were isolated. Using transmission electron microscopy (TEM the morphological changes of S. aureus cells in the mixed culture with standard strains of Lactobacillus plantarum 8P-A3 and clinical strains of L. fermentum (n = 4 were studied. It was found that in 48 hours after the inoculation on the medium of samples of mixed cultures of L. plantarum 8P-A3 and S. aureus growth of staphylococci was not revealed. Only in some cases of mixed cultures of L. fermentum and biofilm-forming staphylococci was growth of S. aureus obtained. In electron diffraction patterns of control samples of 24-hour staphylococcal monocultures and 48-hour lactobacilli monocultures, natural development of the population at the cellular level was observed. Destructive changes under the influence of lactobacilli (probiotic and clinical strains were detected in all ultrathin sections of the cells of biofilm-forming and planktonic staphylococci. Significant destructive changes in the cell wall of the staphylococci were observed: thickening, obtaining of irregular form, detachment of the cytoplasmic membrane, the complete destruction of the peptidoglycan layer and the emergence of "shadow cells". On all electron diffraction patterns fibrillar-threadlike structures of DNA could not be observed, but in some cases mesosome-like formations were poorly contrasted. It was established that the surface S-layer of lactobacilli was expressed on a significantly larger scale in the mixed culture with staphylococci. In mixed culture of clinical strains

  12. North by north-west: climate change and directions of density shifts in birds.

    Lehikoinen, Aleksi; Virkkala, Raimo

    2016-03-01

    There is increasing evidence that climate change shifts species distributions towards poles and mountain tops. However, most studies are based on presence-absence data, and either abundance or the observation effort has rarely been measured. In addition, hardly any studies have investigated the direction of shifts and factors affecting them. Here, we show using count data on a 1000 km south-north gradient in Finland, that between 1970-1989 and 2000-2012, 128 bird species shifted their densities, on average, 37 km towards the north north-east. The species-specific directions of the shifts in density were significantly explained by migration behaviour and habitat type. Although the temperatures have also moved on average towards the north north-east (186 km), the species-specific directions of the shifts in density and temperature did not correlate due to high variation in density shifts. Findings highlight that climate change is unlikely the only driver of the direction of species density shifts, but species-specific characteristics and human land-use practices are also influencing the direction. Furthermore, the alarming results show that former climatic conditions in the north-west corner of Finland have already moved out of the country. This highlights the need for an international approach in research and conservation actions to mitigate the impacts of climate change. © 2015 John Wiley & Sons Ltd.

  13. Skating mechanics of change-of-direction manoeuvres in ice hockey players.

    Fortier, Antoine; Turcotte, René A; Pearsall, David J

    2014-11-01

    Ice hockey requires rapid transitions between skating trajectories to effectively navigate about the ice surface. Player performance relates in large part to effective change-of-direction manoeuvres, but little is known about how those skills are performed mechanically and the effect of equipment design on them. The purpose of this study was to observe the kinetics involved in those manoeuvres as well as to compare whether kinetic differences may result between two skate models of varying ankle mobility. Eight subjects with competitive ice hockey playing experience performed rapid lateral (90°) left and right change-of-direction manoeuvres. Kinetic data were collected using force strain gauge transducers on the blade holders of the skates. Significantly greater forces were applied by the outside skate (50-70% body weight, %BW) in comparison to the inside skate (12-24%BW, p Skate model and turn direction had no main effect, though significant mixed interactions between leg side (inside/outside) with skate model or turn direction (p skating change-of-direction tasks.

  14. Altered Ca fluxes and contractile state during pH changes in cultured heart cells

    Kim, D.; Smith, T.W.

    1987-01-01

    The authors studied mechanisms underlying changes in myocardial contractile state produced by intracellular (pH/sub i/) or extracellular (pH 0 ) changes in pH using cultured chick embryo ventricular cells. A change in pH 0 of HEPES-buffered medium from 7.4 to 6.0 or to 8.8 changed the amplitude of cell motion by -85 or +60%, and 45 Ca uptake at 10 s by -29 or +22%, respectively. The pH 0 induced change in Ca uptake was not sensitive to nifedipine but was Na gradient dependent. Changes in pH/sub i/ produced by NH 4 Cl or preincubation in media at pH values ranging from 6.0 to 8.8 failed to alter significantly 45 Ca uptake or efflux. However, larger changes in pH/sub i/ were associated with altered Ca uptake. Changes in pH 0 from 7.5 to 6.0 or to 8.8 were associated with initial changes in 45 Ca efflux by +17 or -18%, respectively, and these effects were not Na dependent. Exposure of cells to 20 mM NH 4 Cl produced intracellular alkalinization and a positive inotropic effect, whereas subsequent removal of NH 4 Cl caused intracellular acidification and a negative inotropic effect. There was, however, a lack of close temporal relationships between pH/sub i/ and contractile state. These results indicated that pH 0 -induced changes in contractile state in cultured heart cells are closely correlated with altered transarcolemmal Ca movements and presumably are due to these Ca flux changes

  15. Cross-Cultural Perspectives on Parent-Adolescent Discrepancies: Existing Findings and Future Directions.

    Rescorla, Leslie A

    2016-10-01

    As summarized in this commentary, the first generation of cross-informant agreement research focused on perceptions of child and adolescent mental health. Contributions of this research include demonstrating that modest cross-informant agreement is a very robust phenomenon, utilizing numerous statistical approaches to measure degree of agreement, and identifying many factors that moderate agreement. An important focus of this work has been using multi-society international comparisons to examine cross-cultural similarities and differences in cross-informant agreement. The articles in this Special Issue represent a significant paradigm shift in which cross-informant agreement is examined as an independent variable predicting a wide variety of outcomes. Furthermore, moving beyond perceptions of adolescent mental health, these articles compare parent and adolescent perceptions of diverse aspects of family functioning (e.g., family conflict, parent-adolescent communication, family relationships, parental authority). Additionally, the research presented in this Special Issue employs innovative and sophisticated statistical techniques. Although the Special Issue represents some first steps toward considering cross-cultural aspects of perceptions of family functioning, much work still needs to be done in this area. Some suggestions for future research strategies to accomplish this goal conclude this commentary.

    2017-10-25

    Most cell sheet engineering systems require a support or carrier to handle the harvested cell sheets. In this study, polyethylene terephthalate-based overhead projection transparency sheets (OHPS) were subjected to surface hydrolysis by alkali treatment to increase pliability and hydrophilicity and enable poly(N-isopropylacrylamide-co-glycidylmethacrylate) copolymer (NGMA) coating to impart thermoresponsiveness. NGMA was applied on the modified OHPS by the technique of spin coating using an indigenously designed spin coater. The spin coating had the advantage of using low volumes of the polymer and a reduced coating time. The surface chemistry and thermoresponsive coating was analyzed by Fourier transform infrared spectroscopy and water contact angle. Human keratinocyte cells were cultured on the spin coated surface and scaffold-free cell sheets were successfully harvested by simple variation of temperature. These cell sheets were found to be viable, exhibited epithelial characteristic and cell-cell contact as confirmed by positive immunostaining for ZO-1. The integrity and morphology of the cell sheet was confirmed by stereomicroscopy and E-SEM. These results highlight the potential of the NGMA spin coated modified OHPS to serve as a thermoresponsive culture surface-cum-flexible transfer tool.

    Quality collaboratives are widely endorsed as a potentially effective method for translating and spreading best practices for acute myocardial infarction (AMI) care. Nevertheless, hospital success in improving performance through participation in collaboratives varies markedly. We sought to understand what distinguished hospitals that succeeded in shifting culture and reducing 30-day risk-standardised mortality rate (RSMR) after AMI through their participation in the Leadership Saves Lives (LSL) collaborative. We conducted a longitudinal, mixed methods intervention study of 10 hospitals over a 2-year period; data included surveys of 223 individuals (response rates 83%-94% depending on wave) and 393 in-depth interviews with clinical and management staff most engaged with the LSL intervention in the 10 hospitals. We measured change in culture and RSMR, and key aspects of working related to team membership, turnover, level of participation and approaches to conflict management. The six hospitals that experienced substantial culture change and greater reductions in RSMR demonstrated distinctions in: (1) effective inclusion of staff from different disciplines and levels in the organisational hierarchy in the team guiding improvement efforts (referred to as the 'guiding coalition' in each hospital); (2) authentic participation in the work of the guiding coalition; and (3) distinct patterns of managing conflict. Guiding coalition size and turnover were not associated with success (p values>0.05). In the six hospitals that experienced substantial positive culture change, staff indicated that the LSL learnings were already being applied to other improvement efforts. Hospitals that were most successful in a national quality collaborative to shift hospital culture and reduce RSMR showed distinct patterns in membership diversity, authentic participation and capacity for conflict management. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

    2018-04-01

    Full Text Available The purpose of this study was to investigate the influence that different frequencies of deceleration and acceleration actions had on the physiological demands in professional soccer players. Thirteen players were monitored via microelectromechanical devices during shuttle running protocols which involved one, three, or seven 180 degree directional changes. Heart rate exertion (HRE (1.1 ± 0.7 and rating of perceived exertion (RPE (5 ± 1 were significantly higher for the protocol which included seven directional changes when compared to the protocols which included one (HRE 0.5 ± 0.3, ES = 1.1, RPE 3 ± 0, ES = 2.7 or three (HRE 0.5 ± 0.2, ES = 1.1, RPE 3 ± 1, ES = 1.9 directional changes (p < 0.05. The gravitational force (g-force as measured through accelerometry (ACC also showed a similar trend when comparing the seven (8628.2 ± 1630.4 g to the one (5888.6 ± 1159.1 g, ES = 1.9 or three (6526.9 ± 1257.6 g, ES = 1.4 directional change protocols (p < 0.05. The results of this study suggest that increasing the frequency of decelerations and accelerations at a high intensity running (HIR speed alters the movement demands and elevates the physiological responses in professional players. This data has implications for the monitoring of physical performance and implementation of training drills.

  1. Changing effects of direct-to-consumer broadcast drug advertising information sources on prescription drug requests.

    Lee, Annisa Lai

    2009-06-01

    This study tracks the changes of the effects of 4 information sources for direct-to-consumer drug advertising on patients' requests for prescription drugs from physicians since the inception of the "Guidance for Industry about Consumer-directed Broadcast Advertisements." The Guidance advises pharmaceuticals to use four information sources for consumers to seek further information to supplement broadcast drug advertisements: small-print information, the Internet, a toll-free number, and health-care providers (nurses, doctors, and pharmacists). Logistic models were created by using survey data collected by the Food and Drug Administration in 1999 and 2002. Results show that throughout the years, health-care providers remain the most used and strongest means associated with patients' direct requests for nonspecific and specific prescription drugs from doctors. The small-print information source gains power and changes from an indirect means associated with patients' discussing drugs with health-care providers to a direct means associated with patients' asking about nonspecific and specific drugs from their doctors. The Internet is not directly related to drug requests, but the effect of its association with patients seeking information from health-care providers grew 11-fold over the course of the study. The toll-free number lost its power altogether for both direct request for a prescription drug and further discussion with health-care providers. Patient demographics will be considered for specific policy implications.

  2. Climate knowledge cultures: Stakeholder perspectives on change and adaptation in Nusa Tenggara Barat, Indonesia

    E.L. Bohensky

    2016-01-01

    Full Text Available Effective climate adaptation requires engagement (awareness, motivation, and capacity to act at relevant scales, from individuals to global institutions. In many parts of the world, research attention has focused on the engagement of the general public. We suggest that studies also need to focus on key stakeholders in the government and non-governmental sectors who participate in adaptation planning processes, so that a better understanding may be achieved of the distinct knowledge cultures that influence their engagement with climate change. Indonesia is a key actor in climate adaptation because of the potentially dire consequences for its population’s livelihoods and well-being. In this paper we consider whether ‘climate knowledge cultures’ exist amongst stakeholders at multiple organisational levels in Nusa Tenggara Barat (NTB Province, Eastern Indonesia. Surveys were conducted with 124 stakeholders from differing levels at the beginning of four multi-stakeholder climate adaptation workshops. Questions elicited perceptions of their region’s challenges, observation and awareness of climate change, feelings they associated with climate change, beliefs regarding causes, risks and preparedness for climate change, and timeframes they associated with the future. Across all levels, climate change ranked highest as the first challenge participants identified, followed by food security, but well-being ranked highest when the top three challenges were combined. Most participants believed climate change was happening, but those working at higher organisational levels were more likely to attribute climate change to human factors whereas those at lower levels were more likely to think it was a natural phenomenon. Women were in greater agreement and more optimistic than men about current government policies to cope with climate change. Perceptions differed between sub-districts, reflecting NTB’s climatic diversity. We note that although climate

  3. ‘Inheriting’ our Cultural Heritage: Changes of paradigm of conservation

    Stefano Francesco Musso

    2015-02-01

    Full Text Available The world is quickly and deeply changing, facing new challenges in the built environment. Conservation can play a crucial role for preserving the future of the planet, not wasting but rather continuing to use (or reuse the depot of physical traces that the previous ages left us, as provisional responsible for them, in cultural ways and respectful. A crucial question rises apropos: are we really ready and able to inherit this impressive mine of knowledge, “identity” and cultural richness? We cannot in fact go on along the paths that have been traced, within the western world and culture, since more than two centuries about conservation/restoration (with all their contradictions and suggestions. We cannot behave as if nothing has changed and ignoring the problems of the contemporary societies, or like they were external to our commitments, interests and responsibilities. The key-lecture will deal with some of the main challenges that the culture of conservation (or “movement”, as someone could call it will have to face in the near future in order to survive and not to reduce itself to an ancillary role and to an un-influencing condition within the contemporary world. A particular focus will be put for this reason on the crucial role that ICT play also in this field.

  5. Popular culture and the "new human condition": Catastrophe narratives and climate change

    Bulfin, Ailise

    2017-09-01

    Striking popular culture images of burnt landscapes, tidal waves and ice-bound cities have the potential to dramatically and emotively convey the dangers of climate change. Given that a significant number of people derive a substantial proportion of their information on the threat of climate change, or the ;new human condition;, from popular culture works such as catastrophe movies, it is important that an investigation into the nature of the representations produced be embedded in the attempt to address the issue. What climate change-related messages may be encoded in popular films, television and novels, how are they being received, and what effects may they have? This article adopts the cultural studies perspective that popular culture gives us an important means by which to access the ;structures of feeling; that characterise a society at a particular historic juncture: the views held and emotional states experienced by significant amounts of people as evident in disparate forms of cultural production. It further adopts the related viewpoint that popular culture has an effect upon the society in which it is consumed, as well as reflecting that society's desires and concerns - although the nature of the effect may be difficult to quantify. From this position, the article puts forward a theory on the role of ecological catastrophe narratives in current popular culture, before going on to review existing critical work on ecologically-charged popular films and novels which attempts to assess their effects on their audiences. It also suggests areas for future research, such as the prevalent but little studied theme of natural and environmental disaster in late-Victorian science fiction writing. This latter area is of interest because it reveals the emergence of an ecological awareness or structure of feeling as early as the late-nineteenth century, and allows the relationship of this development to environmental policy making to be investigated because of the

    Mauseth, Kira B; Skalisky, Jordan; Clark, Noël E; Kaffer, Ray

    2016-08-01

    Through narrative analysis, this paper explores the changes in acceptance of and response to substance use in Muslim culture by evaluating data collected in qualitative interviews in Jordan in 2013. What is known and unknown about substance use in Muslim culture throughout the Arab world from previous research findings provides a foundation from which to explore new perspectives and compare themes between younger and older generations in Jordan. Trends of social change and behavioral expression influenced by dramatic political and social upheaval in the Arab world in the last 5 years will also be evaluated for the way in which they may be influencing both substance use and its acceptance among young adults in this population. Recommendations for future research and work in this area are also provided based on these findings.

Two policies can be adopted in such a situation: (a) consumers can be actively informed regarding the risks and benefits and (b) consumers can be given the opportunity to evaluate products on the basis of direct experience. The effectiveness of both policies was tested in two experiments....... In experiment 1, attitude change experiments were conducted with consumers from Denmark, Germany, Italy and the UK (N=1650). Different information strategies were tested against a control group for their ability to change consumers' attitudes and their influence on product choice. Results indicate...... that no attitude change occured. Instead, all stategies seemed to bolster pre-existing attitudes, thereby significantly decreasing consumers' preferences for GM products. The effect did not occur when consumers only saw a labeled product example. In experiment 2, we tested the effects of direct experience...

  8. National institute for Food and Agriculture: novel and changing funding strategies and mechanisms in response to changes in budgets, legislative authorities and scientific culture

    Cavallaro, N.; Melnick, R.

    2017-12-01

    Farm Bill legislation establishes different funding mechanisms managed by the National Institute of Food and Agriculture (NIFA), which have changed over the years through reauthorization. Other legislation and executive initiatives, as well as recognition by both funders, funding recipients, private organizations, and non-government organizations have stressed the need for multi-, inter-, and trans-disciplinary research and outreach. This presentation will discuss how changes to NIFA legislative authority as well as changing needs and culture in the government and the scientific research community have led to new mechanisms and strategies for types of funded projects, eligibility for NIFA funding, interagency funding, and iterative changes in direction in research solicitations. For example, limited funding for important topics has prompted a need for interagency collaborations in research funding solicitations and jointly funded projects. New legislative authorities and requirements have led to new modes of collaboration with private industry, NGOs and commodity boards along with international alliances. Unlike most funding agencies, NIFA funds education and extension or outreach projects in addition to research projects. New authorities together with increased recognition of scientific research needed to inform societal challenges has led to new thinking and greater flexibility in funding for long-term research projects and larger regional, multi-institutional and multi-national projects. This, in addition to a shifting culture among researchers and research institutions, has aided in new policies, requirements and initiatives among research institutions and government agencies involving information, data sharing and public access. Examples of new mechanisms and programs and their successes along with their drawbacks will be presented.

  9. Towards culture change in the operating theatre: embedding a complex educational intervention to improve teamwork climate.

    Bleakley, Alan; Allard, Jon; Hobbs, Adrian

    2012-01-01

    Changing teamwork climate in healthcare through a collective shift in attitudes and values may be a necessary precursor to establishing a positive teamwork culture, where innovations can be more readily embedded and sustained. A complex educational intervention was initiated across an entire UK Trust's surgical provision, and then sustained. Attitudes towards teamwork were measured longitudinally to examine if the intervention produced sustainable results. The research aimed to test whether sustaining a complex education intervention to improve teamwork would result in an incremental, longitudinal improvement in attitudes and values towards teamwork. The intervention's larger aim is to progress the historical default position of multi-professional work to authentic inter-professional teamwork, as a positive values climate translates in time into behavioural change defining a safety culture. Attitudes were measured at three points across all surgical team personnel over a period of 4 years, using a validated Safety Attitudes Questionnaire with a focus on the 'teamwork climate' domain. Pre- and post-intervention 'teamwork climate' scores were compared to give a longitudinal measure as a test of sustainability. Mean 'teamwork climate' scores improved incrementally and significantly following the series of educational interventions, showing that practitioners' valuing of teamwork activity can be improved and sustained. Longitudinal positive change in attitudes and values towards teamwork can be sustained, suggesting that a deliberate, designed complex intervention can shape a safety climate as a necessary prerequisite for the establishment of a sustainable safety culture.

  10. Saccharomyces cerevisiae gene expression changes during rotating wall vessel suspension culture

    Johanson, Kelly; Allen, Patricia L.; Lewis, Fawn; Cubano, Luis A.; Hyman, Linda E.; Hammond, Timothy G.

    2002-01-01

    This study utilizes Saccharomyces cerevisiae to study genetic responses to suspension culture. The suspension culture system used in this study is the high-aspect-ratio vessel, one type of the rotating wall vessel, that provides a high rate of gas exchange necessary for rapidly dividing cells. Cells were grown in the high-aspect-ratio vessel, and DNA microarray and metabolic analyses were used to determine the resulting changes in yeast gene expression. A significant number of genes were found to be up- or downregulated by at least twofold as a result of rotational growth. By using Gibbs promoter alignment, clusters of genes were examined for promoter elements mediating these genetic changes. Candidate binding motifs similar to the Rap1p binding site and the stress-responsive element were identified in the promoter regions of differentially regulated genes. This study shows that, as in higher order organisms, S. cerevisiae changes gene expression in response to rotational culture and also provides clues for investigations into the signaling pathways involved in gravitational response.

    Direct immunofluorescence assay (DFA) is commonly used for the rapid identification of herpes simplex virus (HSV) infection in mucocutaneous lesions, yet little is known about its diagnostic accuracy. To determine the diagnostic yield and accuracy of HSV DFA for the diagnosis of mucocutaneous HSV infection in pediatric patients. Retrospective cross-sectional study of all patients who underwent HSV DFA testing by the Texas Children's Hospital Diagnostic Virology between January 1, 1995 and December 31, 2005. HSV DFA sensitivity, specificity, positive likelihood ratio (LRs), and negative LRs were estimated using viral culture as the reference standard. 659 specimens were submitted for HSV DFA with concurrent viral cultures. Viral cultures were positive for HSV type 1 in 158 (24%) and HSV type 2 in 2 (0.3%). There were 433 different patients with a median age of 8.6 years. Types of lesions were as follows: 50% ulcerative, 26% vesicular, 8% erythema or purpura, 5% pustular, and 11% missing. Of the 659 specimens submitted for HSV DFA, 160 (24%) were inconclusive due to inadequate cells. Of the 499 adequate specimens, overall HSV DFA test accuracy was: sensitivity 61%, specificity 99%, LR positive 40, and LR negative 0.39. A quarter of specimens submitted for HSV DFA testing are not adequate for DFA testing. When HSV DFA can be performed, it is specific, but not sensitive, for the identification of mucocutaneous HSV infection in children. Copyright (c) 2010 Elsevier B.V. All rights reserved.

  13. Shifting to Value-Based Principles in Sickness Insurance: Challenges in Changing Roles and Culture.

    Ståhl, Christian; Andersson, Frieda

    2018-02-12

    Purpose Management principles in insurance agencies influence how benefits are administered, and how return to work processes for clients are managed and supported. This study analyses a change in managerial principles within the Swedish Sickness Insurance Agency, and how this has influenced the role of insurance officials in relation to discretion and accountability, and their relationship to clients. Methods The study is based on a qualitative approach comprising 57 interviews with officials and managers in four insurance offices. Results The reforms have led to a change in how public and professional accountability is defined, where the focus is shifted from routines and performance measurements toward professional discretion and the quality of encounters. However, the results show how these changes are interpreted differently across different layers of the organization, where New Public Management principles prevail in how line managers give feedback on and reward the work of officials. Conclusions The study illustrates how the introduction of new principles to promote officials' discretion does not easily bypass longstanding management strategies, in this case managing accountability through top-down performance measures. The study points out the importance for public organizations to reconcile new organizational principles with the current organizational culture and how this is manifested through managerial styles, which may be resistant to change. Promoting client-oriented and value-driven approaches in client work hence needs to acknowledge the importance of organizational culture, and to secure that changes are reflected in organizational procedures and routines.

    2016-01-01

    Full Text Available Today the long-term conservation of cultural heritage is a big challenge: often the artworks were subjected to unknown interventions, which eventually were found to be harmful. The noninvasive investigation of the conservation treatments to which they were subjected to is a crucial step in order to undertake the best conservation strategies. We describe here the preliminary results on a quick and direct method for the nondestructive identification of the various interventions of parchment by means of direct analysis in real time (DART ionization and high-resolution time-of-flight mass spectrometry and chemometrics. The method has been developed for the noninvasive analysis of the Dead Sea Scrolls, one of the most important archaeological discoveries of the 20th century. In this study castor oil and glycerol parchment treatments, prepared on new parchment specimens, were investigated in order to evaluate two different types of operations. The method was able to identify both treatments. In order to investigate the effect of the ion source temperature on the mass spectra, the DART-MS analysis was also carried out at several temperatures. Due to the high sensitivity, simplicity, and no sample preparation requirement, the proposed analytical methodology could help conservators in the challenging analysis of unknown treatments in cultural heritage.

    2015-01-01

    The aim of this study was to compare the training effects based on repeated sprint ability (RSA) (with one change of direction) with an intensive repeated sprint ability (IRSA) (with two changes of direction) on jump performance and aerobic fitness. Eighteen male basketball players were assigned to repeated sprint ability and intensive repeated sprint ability training groups (RSAG and IRSAG). RSA, IRSA, squat jump (SJ), countermovement jump (CMJ) and Yo-Yo intermittent recovery level 1 test were assessed before and after four training weeks. The RSA and IRSA trainings consisted of three sets of six sprints (first two weeks) and eight sprints (second two weeks) with 4-min sets recovery and 20-s of sprints recovery. Four weeks of training led to an overall improvement in most of the measures of RSA, but little evidence of any differences between the two training modes. Jump performance was enhanced: CMJ of 7.5% (P training with one/two changes of direction promotes improvements in both RSA and IRSA respectively but the better increase on jump performance shown a few changes on sprint and endurance performances.

  19. Investigating the effects of behavioral change, social support, and self-efficacy in physical activity in a collectivistic culture: Application of Stages of Motivational Readiness for Change in Korean young adults.

    Lee, Dohyun; Young, Sarah J

    2018-06-01

    The study investigated the roles of social support, self-efficacy, and behavioral change in physical activity (PA) in the Korean culture. The subjects were 164 Korean college students. In November 2016, the study participants completed an online survey asking about PA behavior, PA Self-Efficacy, PA Stages of Change (stages of behavioral change in PA), and Social Support for PA. The collected data were statistically analyzed through structural equation modeling. In the results, PA Stages of Change had a direct effect ( β  = 0.57, p  Change as PA Self-Efficacy had a direct effect ( β  = 0.50, p  Change. However, Social Support for PA did not show an effect on other factors. Additionally, Social Support for PA had a correlation of r  = 0.45 ( p  Change is a significant PA predictor. Moreover, high PA Self-Efficacy indirectly helps Korean young adults to be more physically active by fostering advancement on the stages of behavioral change in PA. In contrast, Social Support for PA does not have a significant association with PA or PA Stages of Change. This non-significance of Social Support for PA can be explained with Korea's collectivistic culture. Furthermore, there is a possibility that Social Support for PA can positively affect PA by interacting with PA Self-Efficacy.

In this study, we assessed the accuracy in identification of both Gram-negative and Gram-positive bacteria, except for Streptococcus viridans, using four rapid blood culture methods with Vitek MALDI-TOF-MS. We compared our proposed lysis centrifugation followed by washing and 30% acetic acid treatment method (method 2) with two other lysis centrifugation methods (washing and 30% formic acid treatment (method 1); 100% ethanol treatment (method 3)), and picking colonies from 90 to 180min subculture plates (method 4). Methods 1 and 2 identified all organisms down to species level with 100% accuracy, except for Streptococcus viridans, Streptococcus pyogenes, Enterobacter cloacae and Proteus vulgaris. The latter two were identified to genus level with 100% accuracy. Each method exhibited excellent accuracy and precision in terms of identification to genus level with certain limitations.

    2015-03-07

    Improving outcomes for patients with acute myocardial infarction (AMI) is a priority for hospital leadership, clinicians, and policymakers. Evidence suggests links between hospital organizational culture and hospital performance; however, few studies have attempted to shift organizational culture in order to improve performance, fewer have focused on patient outcomes, and none have addressed mortality for patients with AMI. We sought to address this gap through a novel longitudinal intervention study, Leadership Saves Lives (LSL). This manuscript describes the methodology of LSL, a 2-year intervention study using a concurrent mixed methods design, guided by open systems theory and the Assess, Innovate, Develop, Engage, Devolve (AIDED) model of diffusion, implemented in 10 U.S. hospitals and their peer hospital networks. The intervention has three primary components: 1) annual convenings of the ten intervention hospitals; 2) semiannual workshops with guiding coalitions at each hospital; and 3) continuous remote support across all intervention hospitals through a web-based platform. Primary outcomes include 1) shifts in key dimensions of hospital organizational culture associated with lower mortality rates for patients with AMI; 2) use of targeted evidence-based practices associated with lower mortality rates for patients with AMI; and 3) in-hospital AMI mortality. Quantitative data include annual surveys of guiding coalition members in the intervention hospitals and peer network hospitals. Qualitative data include in-person, in-depth interviews with all guiding coalition members and selective observations of key interactions in care for patients with AMI, collected at three time points. Data integration will identify patterns and major themes in change processes across all intervention hospitals over time. LSL is novel in its use of a longitudinal mixed methods approach in a diverse sample of hospitals, its focus on objective outcome measures of mortality, and its

    Recent archaeomagnetic intensity data from the Levant revealed short-term sub-centennial changes in the geomagnetic field such as `archaeomagnetic jerks' and `geomagnetic spikes'. To fully understand the nature of these fast variations a complementary high-precision time-series of geomagnetic field direction is required. To this end we investigated 35 heat impacted archaeological objects from Israel, including cooking ovens, furnaces, and burnt walls. We combine the new dataset with previously unpublished data and construct the first archaeomagnetic compilation of Israel which, at the moment, consists of a total of 57 directions. Screening out poor quality data leaves 30 acceptable archaeomagnetic directions, 25 of which spanning the period between 1700 BCE to 400 BCE. The most striking result of this dataset is a large directional anomaly with deviation of 20°-25° from geocentric axial dipole direction during the 9th century BCE. This anomaly in field direction is contemporaneous with the Levantine Iron Age Anomaly (LIAA) - a local geomagnetic anomaly over the Levant that was characterized by a high averaged geomagnetic field (nearly twice of today's field) and short decadal-scale geomagnetic spikes.

    Abstract Purpose: By 2006, women constituted 34% of academic medical faculty, reaching a critical mass. Theoretically, with critical mass, culture and policy supportive of gender equity should be evident. We explore whether having a critical mass of women transforms institutional culture and organizational change. Methods: Career development program participants were interviewed to elucidate their experiences in academic health centers (AHCs). Focus group discussions were held with institutional leaders to explore their perceptions about contemporary challenges related to gender and leadership. Content analysis of both data sources revealed points of convergence. Findings were interpreted using the theory of critical mass. Results: Two nested domains emerged: the individual domain included the rewards and personal satisfaction of meaningful work, personal agency, tensions between cultural expectations of family and academic roles, and women's efforts to work for gender equity. The institutional domain depicted the sociocultural environment of AHCs that shaped women's experience, both personally and professionally, lack of institutional strategies to engage women in organizational initiatives, and the influence of one leader on women's ascent to leadership. Conclusions: The predominant evidence from this research demonstrates that the institutional barriers and sociocultural environment continue to be formidable obstacles confronting women, stalling the transformational effects expected from achieving a critical mass of women faculty. We conclude that the promise of critical mass as a turning point for women should be abandoned in favor of “critical actor” leaders, both women and men, who individually and collectively have the commitment and power to create gender-equitable cultures in AHCs.

  5. Changes in chromatin structure during the aging of cell cultures as revealed by differential scanning calorimetry

    Almagor, M.; Cole, R.D.

    1989-01-01

    Nuclei from cultured human cells were examined by differential scanning calorimetry. Their melting profiles revealed four structural transitions at 60, 76, 88, and 105 degrees C (transitions I-IV, respectively). In immortalized (i.e., tumor) cell cultures and in normal cell cultures of low passage number, melting profiles were dominated by the 105 degrees C transition (transition IV), but in vitro aging of normal and Werner syndrome cells was associated with a marked decrease in transition IV followed by an increase in transition III at the expense of transition IV. At intermediate times in the aging process, much DNA melted at a temperature range (95-102 degrees C) intermediate between transitions III and IV, and this is consistent with the notion that aging of cell cultures is accompanied by an increase in single-strand character of the DNA. Calorimetric changes were observed in the melting profile of nuclei from UV-irradiated tumor cells that resembled the age-induced intermediate melting of chromatin. It is suggested that aging is accompanied by an increase in single-stranded character of the DNA in chromatin, which lowers its melting temperature, followed by strand breaks in the DNA that destroy its supercoiling potential

  7. Reconsidering Parenting in Chinese Culture: Subtypes, Stability, and Change of Maternal Parenting Style During Early Adolescence.

    Zhang, Wenxin; Wei, Xing; Ji, Linqin; Chen, Liang; Deater-Deckard, Kirby

    2017-05-01

    Parenting in Chinese culture has been a central topic and there have been debate on whether western-derived parenting style is applicable to Chinese cultures in terms of both behavioral profiles and their relationships with child and adolescent adjustment. This study identified the subtypes of Chinese maternal parenting style and examined their stability and changes over the transition to early adolescence. In an urban Chinese sample (N = 2173, 48% girls), four waves of longitudinal data were collected when the adolescents were in the fifth (M = 11.27 years), sixth, seventh, and eighth grades. Latent profile analysis identified four subtypes of parenting style: authoritative, authoritarian, average-level undifferentiated, and strict-affectionate. Adolescents of authoritative mothers exhibited the best overall adjustment, while adolescents of authoritarian mothers showed the worst adjustment. Adolescents of strict-affectionate mothers generally adjusted as well as those of authoritative mothers, except they showed lower academic achievement. The strict-affectionate parenting represented a culture-specific subtype of parenting style in Chinese culture. Latent transition analysis revealed high stability of parenting styles during early adolescence, but transitions between subtypes were also evident. These findings highlight the importance of revisiting Chinese parenting and examining the developmental course of parenting style.

  8. Social care going market : Institutional and cultural change regarding services for the elderly

    2015-03-01

    Full Text Available Over the last two decades or so, major Western societies have remoulded the institutional set-up by which they are deailing with social risks related to frailty during old age. While the 20th century had brought a transnational tendency towards the establishment of elderly care ‘going public’, the proliferation of more market-based services brings confusion into the societal norm-set underlying the aforementioned tendency. Marketisation has placed the emphasis on economic values engrained in liberal worldviews, leading into a new welfare culture that devaluates universalism and reemphasises the sovereignty of the individual. However, the new cult of the individual produces contradictory signals. Drawing on an encompassing study on the ‘culture of welfare markets’ in elderly care provision, covering two (post-liberal and two (post-corporatist welfare regimes (Canada, Britain; France, Germany, the paper looks at these fuzzy developments in order to assess the cultural embeddedness of what can be referred to as the mixed economy of elderly care. The analysis, charting major patterns of both institutional change and public communication around it, elucidates that we currently are facing a permanent struggle between liberal values and (renewed elements of the ‘going-public-agenda’ proliferating over the 1970s and 1980s, that is, a hybrid and ‘nervous’ cultural configuration in which senior social citizenship remains an issue, albeit on precarious foundations.

  9. An exploration of potential directions for climate change policy in Northern Canada

    Newton, J.

    2001-01-01

    The challenges facing decision and policy makers for climate change actions in the Canadian North were described. While Northern Canada contributes only a small fraction of the world's greenhouse gas (GHG) emissions, the impacts are already being felt there, and scientists forecast changes in average annual temperatures to be among the highest in the world. Canada is well positioned to take a lead role in addressing climate change in northern regions. This paper examined the policy choices in the North and outlined the policy directions worthy of further consideration and development. The objective of the paper is to provide a catalyst for on-going discussion and deliberation on climate change actions and policy options in Northern Canada. The paper also addressed the global context that influences national framework and local initiatives. Some tentative policy choices were proposed and described within the general context of the global challenge that climate change presents for the design of coherent regional public policy. It was suggested that integration and mitigation measures should not be approached in isolation from other environmental and socio-economic changes, such as pollution abatement and economic and social development. It was emphasized that building on the sound foundation of current policy frameworks in these areas is essential to the integration of climate change initiatives within established and complementary processes. It was concluded that the evolution of policy options for climate change in the North will be driven by a political willingness to take deliberate actions. 13 refs., 2 tabs., 1 fig

  10. Local Fitness Landscapes Predict Yeast Evolutionary Dynamics in Directionally Changing Environments.

    Gorter, Florien A; Aarts, Mark G M; Zwaan, Bas J; de Visser, J Arjan G M

    2018-01-01

    The fitness landscape is a concept that is widely used for understanding and predicting evolutionary adaptation. The topography of the fitness landscape depends critically on the environment, with potentially far-reaching consequences for evolution under changing conditions. However, few studies have assessed directly how empirical fitness landscapes change across conditions, or validated the predicted consequences of such change. We previously evolved replicate yeast populations in the presence of either gradually increasing, or constant high, concentrations of the heavy metals cadmium (Cd), nickel (Ni), and zinc (Zn), and analyzed their phenotypic and genomic changes. Here, we reconstructed the local fitness landscapes underlying adaptation to each metal by deleting all repeatedly mutated genes both by themselves and in combination. Fitness assays revealed that the height, and/or shape, of each local fitness landscape changed considerably across metal concentrations, with distinct qualitative differences between unconditionally (Cd) and conditionally toxic metals (Ni and Zn). This change in topography had particularly crucial consequences in the case of Ni, where a substantial part of the individual mutational fitness effects changed in sign across concentrations. Based on the Ni landscape analyses, we made several predictions about which mutations had been selected when during the evolution experiment. Deep sequencing of population samples from different time points generally confirmed these predictions, demonstrating the power of landscape reconstruction analyses for understanding and ultimately predicting evolutionary dynamics, even under complex scenarios of environmental change.

  11. Flexibility to contingency changes distinguishes habitual and goal-directed strategies in humans.

    Lee, Julie J; Keramati, Mehdi

    2017-09-01

    Decision-making in the real world presents the challenge of requiring flexible yet prompt behavior, a balance that has been characterized in terms of a trade-off between a slower, prospective goal-directed model-based (MB) strategy and a fast, retrospective habitual model-free (MF) strategy. Theory predicts that flexibility to changes in both reward values and transition contingencies can determine the relative influence of the two systems in reinforcement learning, but few studies have manipulated the latter. Therefore, we developed a novel two-level contingency change task in which transition contingencies between states change every few trials; MB and MF control predict different responses following these contingency changes, allowing their relative influence to be inferred. Additionally, we manipulated the rate of contingency changes in order to determine whether contingency change volatility would play a role in shifting subjects between a MB and MF strategy. We found that human subjects employed a hybrid MB/MF strategy on the task, corroborating the parallel contribution of MB and MF systems in reinforcement learning. Further, subjects did not remain at one level of MB/MF behaviour but rather displayed a shift towards more MB behavior over the first two blocks that was not attributable to the rate of contingency changes but rather to the extent of training. We demonstrate that flexibility to contingency changes can distinguish MB and MF strategies, with human subjects utilizing a hybrid strategy that shifts towards more MB behavior over blocks, consequently corresponding to a higher payoff.

  12. Changes in motor unit recruitment strategy during pain alters force direction.

    Tucker, Kylie J; Hodges, Paul W

    2010-10-01

    Motor unit (MU) recruitment is altered (decreased discharge rate and cessation of discharge in some units, and recruitment of new units) in force-matched contractions during pain compared to contractions performed before pain. As MU's within a motoneurone pool have different force direction properties we hypothesised that altered MU recruitment during experimental knee pain would change the force vector (total force (F(T)): amplitude and angle) generated by the quadriceps. Force was produced at two levels during 1 × 60-s and 3 × 10-s isometric contractions of knee extensors, and recorded by two force transducers at right angles. This enabled calculation of both F(E) (extension force) and F(T). MU recruitment was recorded from the medial and lateral vastii with four fine-wire electrodes. Pain was induced by hypertonic saline injection in the infra-patella fat pad. Nine subjects matched F(E) and six subjects also matched both medial and lateral forces (F(T)) before and during pain. Changes in MU discharge pattern (decreased discharge rate (Precruitment of new units) during pain were associated with a ∼5° change in absolute force angle. As force angle changed in both directions (left/right) for individual subjects with pain there was no change in average F(T) amplitude between conditions. When both medial and lateral forces were matched MU discharge rate decreased (Punits ceased firing or were newly recruited during pain. Change in motoneurone recruitment during pain alters direction of muscle force. This may be a strategy to avoid pain or protect the painful part.

  13. Rectal culture-directed antibiotic prophylaxis before transrectal prostate biopsy: Reduced infectious complications and healthcare costs.

    Baldissera-Aradas, J V; Rodríguez-Villamil, L; Blanco-Fernández, R; Pérez-García, C; Viejo de la Guerra, G; González-Rodríguez, I; Mosquera-Madera, J

    2018-01-10

    Transrectal ultrasound-guided prostate biopsy (TUPB) is associated with infectious complications (ICs), which are related to a greater prevalence of ciprofloxacin-resistant bacteria (CRB) in rectal flora. We examined the ICs that occurred in 2 groups: A guided antibiotic prophylaxis (GP) group and an empiric prophylaxis (EP) group. We assessed the financial impact of GP. The GP group was studied prospectively (June 2013 to July 2014). We collected rectal cultures (RCs) before the TUPB, which were seeded on selective media with ciprofloxacin to determine the presence of CRB. The patients with sensitive bacteria were administered ciprofloxacin. Patients with resistant bacteria were administered GP according to the RC antibiogram. The EP group was studied retrospectively (January 2011 to June 2009). RCs were not performed, and all patients were treated with ciprofloxacin as prophylaxis. The ICs in both groups were recorded during a period no longer than 30 days following TUPB (electronic medical history). Three hundred patients underwent TUPB, 145 underwent GP, and 155 underwent EP. In the GP group, 23 patients (15.86%) presented CRB in the RCs. Only one patient (0.7%) experienced a UTI. In the EP group, 26 patients (16.8%) experienced multiple ICs (including 2 cases of sepsis) (P<.005). The estimated total cost, including the management of the ICs, was €57,076 with EP versus €4802.33 with GP. The average cost per patient with EP was €368.23 versus €33.11 with GP. GP achieved an estimated total savings of €52,273.67. Six patients had to undergo GP to prevent an IC. GP is associated with a marked decrease in the incidence of ICs caused by CRB and reduced healthcare costs. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

  14. The work and recovery project: changing organizational culture and practice in New York City outpatient services.

    Pascaris, Alysia; Shields, Leslie Reed; Wolf, Jessica

    2008-01-01

    Complex and multiple barriers confront out-patient programs in promoting recovery and addressing mental health recipients' work-related goals. This article describes a focused organizational change project utilizing intensive consultation and technical assistance within five New York City outpatient psychiatric services. The project aimed to increase staff exposure to, understanding and use of work-related and recovery-based concepts to promote consumers' recovery and attainment of employment goals. Tailored assessment, curriculum delivery, and identification and implementation of change objectives were useful strategies in promoting change. This change model can serve to assist programs in their efforts to integrate new approaches and to better understand changes among leadership, staff and consumers, and changes in organizational culture and practice required to support a work and recovery-oriented service paradigm. The project experience suggests that adopting and embracing new practices takes time. Varied and incremental steps toward programmatic and operational changes can be significant and can reap authentic sustainable change occurring in the process of learning, experiencing, internalizing and adjusting to new methods of practice.

  15. Measuring perceptions of climate change in northern Alaska: pairing ethnography with cultural consensus analysis

    Courtney Carothers

    2014-12-01

    Full Text Available Given current and projected warming trends in the Arctic and the important role played by subsistence hunting and fishing in the life of northern rural communities, it is increasingly important to document local observations of climate change and its impacts on livelihood practices. We describe ethnographic research exploring local observations of climate changes and related impacts on subsistence fisheries in three Iñupiat communities in northwest Alaska and six Athabascan communities in the Yukon River drainage. We found consistent agreement among perceptions concerning a broad range of environmental changes affecting subsistence practices in these communities. These observations of environmental changes are not experienced in isolation but within the context of accompanying social changes that are continually reshaping rural Alaskan communities and subsistence economies. In this paper we reflect on our research approach combining multiple methods of inquiry. Participant observation and semidirected interviews provided the conceptual framework for broadening our focus from climate and environmental change to community residents' understanding of climate change in the context of their holistic human-environment worldview. Cultural consensus analysis allowed us to assess the extent to which perceptions of change are shared among hunters and fishers within and between villages and regions and to identify those phenomena occurring or experienced at smaller scales. Reflecting on this multimethods approach, we highlight important questions that have emerged about how we understand, synthesize, and represent local knowledge, especially as it is used in regulatory or management arenas.

    2017-08-01

    Enhanced interpersonal relationships and meaningful resident engagement in daily life are central to nursing home cultural transformation, yet these critical components of person-centered care may be difficult for frontline staff to measure using traditional research instruments. To address the need for easy-to-use instruments to help nursing home staff members evaluate and improve person-centered care, the psychometric method of cognitive-based interviewing was used to adapt a structured observation instrument originally developed for researchers and nursing home surveyors. Twenty-eight staff members from 2 Veterans Health Administration (VHA) nursing homes participated in 1 of 3 rounds of cognitive-based interviews, using the instrument in real-life situations. Modifications to the original instrument were guided by a cognitive processing model of instrument refinement. Following 2 rounds of cognitive interviews, pretesting of the revised instrument, and another round of cognitive interviews, the resulting set of 3 short instruments mirrored the concepts of the original longer instrument but were significantly easier for frontline staff to understand and use. Final results indicated frontline staff found the revised instruments feasible to use and clinically relevant in measuring and improving the lived experience of a changing culture. This article provides a framework for developing or adapting other measurement tools for frontline culture change efforts in nursing homes, in addition to reporting on a practical set of instruments to measure aspects of person-centered care.

  17. Role of the Enterprise Corporate Culture in Concepts of Organisational Changes

    Otenko Irina Pavlovna

    2013-11-01

    Full Text Available The article analyses the “corporate culture” notion, which is an efficient instrument in the sphere of management of human resources, which influences enterprise competitiveness and factually is a must for high-quality and effective conduct of business. Corporate culture is “reduction” of the most important provisions of activity of the organisation, which identify its mission and development strategy, find their expression in a combination of social norms and values shared by majority of the employees. Corporate culture, as an indicator, characterises the level of development and operation of the organisation, since it influences, first of all, the socio-psychological climate, which sets the emotional background for activity of the whole personnel. Study of the role of corporate culture in concepts of organisational changes would allow using it as a factor of overcoming resistance of the personnel when realising changes and carrying out socio-psychological provision of managerial processes. In this event the organisation functions as an integral body and acts harmoniously to achieve the set goals.

    2017-01-01

    This study was done to analyze the relationship between the various effects of five different doses of gamma ray treatments (control, 0, 100, 200, 300 and 400 rad) on cell suspension culture of Nerium oleander belonging to the family Apocynaceae, Plant samples were collected from Egyptian flora. The five treatments of the plants were characterized by analyzing variability in frozen biomass cell suspension culture of N. oleander through SDS PAGE and peroxidase is ozymes. The electrophorogram showed a total of 36 bands of proteins with molecular weight ranging from 10 to 225 KDa. The protein diversity analysis was done based on the presence or the absence of bands trhus interpreting their relevance. The his togram analysis clearly showed a high degree of diversity a long these five treatments of the plant. The results of electrophoretic patterns of peroxidase is ozymes that was extracted from frozen biomass cell suspension cultures after receiving the different gamma doses revealed remarkable molecular changes in all treatments. These changes in peroxidase isozymes and protein bands indicate the effect of the different irradiation treatments on the gene expiration

  19. An electrochemical approach to monitor pH change in agar media during plant tissue culture.

    Wang, Min; Ha, Yang

    2007-05-15

    In this work, metal oxide microelectrodes were developed to monitor pH change in agar media during plant tissue culture. An antimony wire was produced by a new approach "capillary melt method". The surface of the obtained antimony wire was oxidized in a potassium nitrate melt to fabricate an antimony oxide film for pH sensing. Characterization results show that the oxide layer grown on the wire surface consists of Sb(2)O(3) crystal phase. The sensing response, open-circuit potential, of the electrode has a good linear relationship (R(2)=1.00) with pH value of the test solution. Adding organic compounds into the test media would not affect the linear relationship, although the slope of the lines varied with different ingredients added. The antimony oxide electrodes were employed to continuously monitor pH change of agar culture media during a 2-week plant tissue culture of Dendrobium candidum. The antimony oxide electrode fabricated this way has the advantages of low cost, easy fabrication, fast response, and almost no contamination introduced into the system. It would be suitable for in situ and continuous pH measurement in many bio applications.

  20. Direct versus indirect effects of tropospheric humidity changes on the hydrologic cycle

    Sherwood, S C

    2010-01-01

    Abundant evidence indicates that tropospheric specific humidity increases in a warmer atmosphere, at rates roughly comparable to those at constant relative humidity. While the implications for the planetary energy budget and global warming are well recognized, it is the net atmospheric cooling (or surface heating) that controls the hydrologic cycle. Relative humidity influences this directly through gas-phase radiative transfer, and indirectly by affecting cloud cover (and its radiative effects) and convective heating. Simple calculations show that the two indirect impacts are larger than the direct impact by roughly one and two orders of magnitude respectively. Global or regional relative humidity changes could therefore have significant indirect impacts on energy and water cycles, especially by altering deep convection, even if they are too small to significantly affect global temperature. Studies of climate change should place greater emphasis on these indirect links, which may not be adequately represented in models.

    The limitations of the current methods of quantifying the surgical movements of facial bones inspired this study. The aim of this study was the assessment of the accuracy and reproducibility of directly landmarking of 3D DICOM images (Digital Imaging and Communications in Medicine) to quantify the changes in the jaw bones following surgery. The study was carried out on plastic skull to simulate the surgical movements of the jaw bones. Cone beam CT scans were taken at 3mm, 6mm, and 9mm maxillary advancement; together with a 2mm, 4mm, 6mm and 8mm "down graft" which in total generated 12 different positions of the maxilla for the analysis. The movements of the maxilla were calculated using two methods, the standard approach where distances between surface landmarks on the jaw bones were measured and the novel approach where measurements were taken directly from the internal structures of the corresponding 3D DICOME slices. A one sample t-test showed that there was no statistically significant difference between the two methods of measurements for the y and z directions, however, the x direction showed a significant difference. The mean difference between the two absolute measurements were 0.34±0.20mm, 0.22±0.16mm, 0.18±0.13mm in the y, z and x directions respectively. In conclusion, the direct landmarking of 3D DICOM image slices is a reliable, reproducible and informative method for assessment of the 3D skeletal changes.

    Anas Almukhtar

    Full Text Available The limitations of the current methods of quantifying the surgical movements of facial bones inspired this study. The aim of this study was the assessment of the accuracy and reproducibility of directly landmarking of 3D DICOM images (Digital Imaging and Communications in Medicine to quantify the changes in the jaw bones following surgery. The study was carried out on plastic skull to simulate the surgical movements of the jaw bones. Cone beam CT scans were taken at 3mm, 6mm, and 9mm maxillary advancement; together with a 2mm, 4mm, 6mm and 8mm "down graft" which in total generated 12 different positions of the maxilla for the analysis. The movements of the maxilla were calculated using two methods, the standard approach where distances between surface landmarks on the jaw bones were measured and the novel approach where measurements were taken directly from the internal structures of the corresponding 3D DICOME slices. A one sample t-test showed that there was no statistically significant difference between the two methods of measurements for the y and z directions, however, the x direction showed a significant difference. The mean difference between the two absolute measurements were 0.34±0.20mm, 0.22±0.16mm, 0.18±0.13mm in the y, z and x directions respectively. In conclusion, the direct landmarking of 3D DICOM image slices is a reliable, reproducible and informative method for assessment of the 3D skeletal changes. The method has a clear clinical application which includes the analysis of the jaw movements "orthognathic surgery" for the correction of facial deformities.

  5. The Impact of Globalisation on Changes in Business Operations and Organisational Culture

    Full Text Available Croatian companies have recently been forced to find and apply new technical and technological solutions as a result of large-scale changes and market globalisation. Furthermore, they have to adapt their organisation to the newly-developed conditions. Therefore, it is of utmost importance to consider the use of the latest theoretical findings in the field of organisation and management to reach the level of competitiveness on a global scale. Development, improvement and standardisation of business processes and changes in organisational culture are important preconditions for reforming the companies to meet the needs of globalisation. The goal of this paper is to show the growing impact of globalisation on the development of the business environment in Croatia, i.e. the need to restructure Croatian companies according to the newly-developed situation. There are companies that have to radically change their ways and methods of leadership and thinking, inherited from the socialist socio-economic system. Recurrent crises in the business practice and bankruptcies of economic entities prove this fact. One of the key preconditions to compete successfully in the newly developed global products, work and capital markets is the improvement of business performance by introducing contemporary methods in organisational planning. On the other hand, privatised companies that are under pressure from their foreign owners have to introduce the rules of behaviour and procedures standardised abroad. To sum up, the changes that have to be made require a radical shift in organisational culture within companies. These aspects are often forgotten by consultants and managers, thus leading to failure. The main objectives of this paper are to underline the importance of two preconditions that have to be met in order to succeed, i.e. survive in the market: to define and standardise business processes and to develop organisational culture in companies.

  6. Collision recognition and direction changes for small scale fish robots by acceleration sensors

    Typical obstacles are walls, rocks, water plants and other nearby robots for a group of small scale fish robots and submersibles that have been constructed in our lab. Sonar sensors are not employed to make the robot structure simple enough. All of circuits, sensors and processor cards are contained in a box of 9 x 7 x 4 cm dimension except motors, fins and external covers. Therefore, image processing results are applied to avoid collisions. However, it is useful only when the obstacles are located far enough to give images processing time for detecting them. Otherwise, acceleration sensors are used to detect collision immediately after it happens. Two of 2-axes acceleration sensors are employed to measure the three components of collision angles, collision magnitudes, and the angles of robot propulsion. These data are integrated to calculate the amount of propulsion direction change. The angle of a collision incident upon an obstacle is the fundamental value to obtain a direction change needed to design a following path. But there is a significant amount of noise due to a caudal fin motor. Because caudal fin provides the main propulsion for a fish robot, there is a periodic swinging noise at the head of a robot. This noise provides a random acceleration effect on the measured acceleration data at the collision. We propose an algorithm which shows that the MEMS-type accelerometers are very effective to provide information for direction changes in spite of the intrinsic noise after the small scale fish robots have made obstacle collision.

    The dynamic changes of muscarinic receptor density and its reactivity during aging process in primary cultured neutrons were studied. Muscarinic receptor density was measured by 3 H-QNB binding assay, and muscarinic receptor reactivity was assessed by carbachol stimulation of cGMP formation, the latter was measured by RIA. After 2 weeks' incubation of neonatal rat brain cells, the nutrients began to rupture and the cell bodies shrank markedly showing senescent feature. The muscarinic receptor density reached peak at the 12th day in vitro (12 DIV), but the muscarinic receptor reactivity reached peak at 9 DIV and declined significantly at 12 DIV. The results demonstrated that during aging process of primary cultured neutrons, the decline of muscarinic receptor reactivity is likely prior to the decrease of receptor density

  8. Why change habits? Early modern medical innovation between medicalisation and medical culture.

    Loetz, Francisca

    2010-01-01

    Based on a discussion of the concept of medicalisation and medical culture in Anglo-American, French-, and German-speaking historiography the paper argues that medical innovation in Europe from the sixteenth to the mid-nineteenth century should be approached in a different way. Instead of asking from the perspective of a too narrow concept of medicalisation why medical innovations were rejected by the population, (medical) historians should analyse medical culture and ask why people should have changed their health and illness behaviour. This conceptual argument is deduced from four empirical examples: the introduction of smallpox vaccination, "medical police," the problem of medical professionalization, and the questions arising around the relations between the healthy/sick and their practitioners.

  9. Direct observations of ice seasonality reveal changes in climate over the past 320–570 years

    Lake and river ice seasonality (dates of ice freeze and breakup) responds sensitively to climatic change and variability. We analyzed climate-related changes using direct human observations of ice freeze dates (1443–2014) for Lake Suwa, Japan, and of ice breakup dates (1693–2013) for Torne River, Finland. We found a rich array of changes in ice seasonality of two inland waters from geographically distant regions: namely a shift towards later ice formation for Suwa and earlier spring melt for Torne, increasing frequencies of years with warm extremes, changing inter-annual variability, waning of dominant inter-decadal quasi-periodic dynamics, and stronger correlations of ice seasonality with atmospheric CO2 concentration and air temperature after the start of the Industrial Revolution. Although local factors, including human population growth, land use change, and water management influence Suwa and Torne, the general patterns of ice seasonality are similar for both systems, suggesting that global processes including climate change and variability are driving the long-term changes in ice seasonality.

    Most problem gamblers do not seek formal treatment, recovering on their own through cognitive re-appraisal or self-help strategies. Although barriers to treatment have been extensively studied, there is a paucity of research on self-directed changes in problem gambling and very few studies have examined these changes prospectively. The aim of this study was to examine the trajectory of gambling severity and behavior change over an 18-month period, among a sample of non-treatment seeking/attending problem gamblers recruited from the community (N = 204) interested in quitting or reducing gambling. Separate mixed effects models revealed that in absence of formal treatment, significant reductions in gambling severity, frequency, and amount gambled could be observed over the course of a 6 to 9-month period and that changes experienced within the first 12 months were maintained for an extended 6 months. Problem gambling severity at baseline was significantly associated with changes in severity over time, such that participants with more severe gambling problems demonstrated greater reductions in their gambling severity over time. A total of 11.1% of participants gambled within a low-risk threshold at 18 months, although 28.7% of the sample reported consecutive gambling severity scores below problem levels for the duration of 1 year or longer. The findings suggest that among problem gamblers motivated to quit or reduce their gambling, significant self-directed changes in gambling severity can occur over a relatively short time. Additional prospective studies are needed to document the role of specific self-help tools or thought processes in exacting gambling changes.

    Oligosaccharides attached to Asn297 in each of the CH2 domains of monoclonal antibodies play an important role in antibody effector functions by modulating the affinity of interaction with Fc receptors displayed on cells of the innate immune system. Rapid, detailed, and quantitative N-glycan analysis is required at all stages of bioprocess development to ensure the safety and efficacy of the therapeutic. The high sample numbers generated during quality by design (QbD) and process analytical technology (PAT) create a demand for high-performance, high-throughput analytical technologies for comprehensive oligosaccharide analysis. We have developed an automated 96-well plate-based sample preparation platform for high-throughput N-glycan analysis using a liquid handling robotic system. Complete process automation includes monoclonal antibody (mAb) purification directly from bioreactor media, glycan release, fluorescent labeling, purification, and subsequent ultra-performance liquid chromatography (UPLC) analysis. The entire sample preparation and commencement of analysis is achieved within a 5-h timeframe. The automated sample preparation platform can easily be interfaced with other downstream analytical technologies, including mass spectrometry (MS) and capillary electrophoresis (CE), for rapid characterization of oligosaccharides present on therapeutic antibodies.

    Full Text Available Kunwoo Lee,1,2 Pengzhi Yu,3 Nithya Lingampalli,1 Hyun Jin Kim,1 Richard Tang,1 Niren Murthy1,2 1Department of Bioengineering, University of California, Berkeley, CA, USA; 2UC Berkeley and UCSF Joint Graduate Program in Bioengineering, Berkeley/San Francisco, CA, USA; 3Gladstone Institute of Cardiovascular Disease, San Francisco, CA, USA Abstract: The treatment of myocardial infarction is a major challenge in medicine due to the inability of heart tissue to regenerate. Direct reprogramming of endogenous cardiac fibroblasts into functional cardiomyocytes via the delivery of transcription factor mRNAs has the potential to regenerate cardiac tissue and to treat heart failure. Even though mRNA delivery to cardiac fibroblasts has the therapeutic potential, mRNA transfection in cardiac fibroblasts has been challenging. Herein, we develop an efficient mRNA transfection in cultured mouse cardiac fibroblasts via a polyarginine-fused heart-targeting peptide and lipofectamine complex, termed C-Lipo and demonstrate the partial direct reprogramming of cardiac fibroblasts towards cardiomyocyte cells. C-Lipo enabled the mRNA-induced direct cardiac reprogramming due to its efficient transfection with low toxicity, which allowed for multiple transfections of Gata4, Mef2c, and Tbx5 (GMT mRNAs for a period of 2 weeks. The induced cardiomyocyte-like cells had α-MHC promoter-driven GFP expression and striated cardiac muscle structure from a-actinin immunohistochemistry. GMT mRNA transfection of cultured mouse cardiac fibroblasts via C-Lipo significantly increased expression of the cardiomyocyte marker genes, Actc1, Actn2, Gja1, Hand2, and Tnnt2, after 2 weeks of transfection. Moreover, this study provides the first direct evidence that the stoichiometry of the GMT reprogramming factors influence the expression of cardiomyocyte marker genes. Our results demonstrate that mRNA delivery is a potential approach for cardiomyocyte generation. Keywords: direct cardiac

  13. Cultural and social change of foreign students in Indonesia: The influence of Javanese Culture in Teaching Indonesian to Speakers of Other Languages (TISOL)

    Saddhono, Kundharu

    2018-03-01

    Teaching Indonesian to Speakers of Other Languages (TISOL) program is increasingly in demand by people in various parts of the world. Foreign students learn a lot of Indonesian language in major cities in Indonesia. The purpose of this study is to explain the cultural and social changes of foreign students in Indonesia, especially in Java, which is following TISOL program. This study focused on the influence of Javanese culture on foreign students studying Indonesian in Java. Research method used is descriptive qualitative with ethnography approach. This research was conducted in TISOL program organized by in Central Java, East Java, and Yogyakarta. Sources of data used are documents and informants. The sampling technique used is purposive sampling. Purposive sampling is considered more capable to obtain complete data in the face of various realities. Data collection techniques are done by reviewing documents or records using content analysis techniques. Other techniques used are interview techniques with some students and lecturers to get data about the factors that affect the cultural and social changes of foreign students in Indonesia. Also, interviews were also conducted with teachers to request a different process in TISOL. The most common way used to improve validity in qualitative research is the triangulation technique. In this study used triangulation theory, triangulation method, and review of informants. The results show that using Javanese culture is very influential in the cultural and social changes of foreign students in Indonesia. Students become more enthusiastic and active in responding to learning in TISOL that is influenced by Javanese culture. The change comes from internal and external students. This change helps foreign students to understand Indonesian language and culture more comprehensively.

  14. Organizational culture

    Schein, Edgar H.

    1988-01-01

    Cultural orientations of an organization can be its greatest strength, providing the basis for problem solving, cooperation, and communication. Culture, however, can also inhibit needed changes. Cultural changes typically happen slowly – but without cultural change, many other organizational changes are doomed to fail. The dominant culture of an organization is a major contributor to its success. But, of course, no organizational culture is purely one type or another. And the existence of sec...

    Cell size and shape affect cellular processes such as cell survival, growth and differentiation1-4, thus establishing cell geometry as a fundamental regulator of cell physiology. The contributions of the cytoskeleton, specifically actomyosin tension, to these effects have been described, but the exact biophysical mechanisms that translate changes in cell geometry to changes in cell behaviour remain mostly unresolved. Using a variety of innovative materials techniques, we demonstrate that the nanostructure and lipid assembly within the cell plasma membrane are regulated by cell geometry in a ligand-independent manner. These biophysical changes trigger signalling events involving the serine/threonine kinase Akt/protein kinase B (PKB) that direct cell-geometry-dependent mesenchymal stem cell differentiation. Our study defines a central regulatory role by plasma membrane ordered lipid raft microdomains in modulating stem cell differentiation with potential translational applications.

  16. Macrosegregation Caused by Convection Associated with Directional Solidification through Cross-Section Change

    Ghods, M.; Lauer, M.; Tewari, S. N.; Poirier, D. R..; Grugel, R. N.

    2015-01-01

    Al-7 wt% Si and Pb-6 wt% Sb alloy samples were directionally solidified (DS), with liquid above and solid below and gravity pointing down, in cylindrical graphite crucibles through an abrupt cross-section change. Fraction eutectic distribution in the microstructure, primary dendrite spacing and primary dendrite trunk diameters have been measured in the DS samples in the vicinity of section change in order to examine the effect of convection associated with the combined influence of thermosolutal factors and solidification shrinkage. It is observed that convection not only produces extensive radial and axial macrosegregation near cross-section change, it also affects the dendritic array morphology. Primary dendrite spacing and primary dendrite trunk diameter, both, are influenced by this convection. In addition to the experimental results, preliminary results from a numerical model which includes solidification shrinkage and thermosolutal convection in the mushy zone in its analysis will also be presented

  17. Direct and indirect effects of climate change on a prairie plant community.

    Peter B Adler

    2009-09-01

    Full Text Available Climate change directly affects species by altering their physical environment and indirectly affects species by altering interspecific interactions such as predation and competition. Recent studies have shown that the indirect effects of climate change may amplify or counteract the direct effects. However, little is known about the the relative strength of direct and indirect effects or their potential to impact population persistence.We studied the effects of altered precipitation and interspecific interactions on the low-density tiller growth rates and biomass production of three perennial grass species in a Kansas, USA mixed prairie. We transplanted plugs of each species into local neighborhoods of heterospecific competitors and then exposed the plugs to a factorial manipulation of growing season precipitation and neighbor removal. Precipitation treatments had significant direct effects on two of the three species. Interspecific competition also had strong effects, reducing low-density tiller growth rates and aboveground biomass production for all three species. In fact, in the presence of competitors, (log tiller growth rates were close to or below zero for all three species. However, we found no convincing evidence that per capita competitive effects changed with precipitation, as shown by a lack of significant precipitation x competition interactions.We found little evidence that altered precipitation will influence per capita competitive effects. However, based on species' very low growth rates in the presence of competitors in some precipitation treatments, interspecific interactions appear strong enough to affect the balance between population persistence and local extinction. Therefore, ecological forecasting models should include the effect of interspecific interactions on population growth, even if such interaction coefficients are treated as constants.

  18. Dynamical response of the magnetotail to changes of the solar wind direction: an MHD modeling perspective

    V. A. Sergeev

    2008-08-01

    Full Text Available We performed global MHD simulations to investigate the magnetotail response to the solar wind directional changes (Vz-variations. These changes, although small, cause significant variations of the neutral sheet shape and location even in the near and middle tail regions. They display a complicated temporal response, in which ~60 to 80% of the final shift of the neutral sheet in Z direction occurs within first 10–15 min (less for faster solar wind, whereas a much longer time (exceeding half hour is required to reach a new equilibrium. The asymptotic equilibrium shape of the simulated neutral sheet is consistent with predictions of Tsyganenko-Fairfield (2004 empirical model. To visualize a physical origin of the north-south tail motion we compared the values of the total pressure in the northern and southern tail lobes and found a considerable difference (10–15% for only 6° change of the solar wind direction used in the simulation. That difference builds up during the passage of the solar wind directional discontinuity and is responsible for the vertical shift of the neutral sheet, although some pressure difference remains in the near tail even near the new equilibrium. Surprisingly, at a given tailward distance, the response was found to be first initiated in the tail center (the "leader effect", rather than near the flanks, which can be explained by the wave propagation in the tail, and which may have interesting implications for the substorm triggering studies. The present results have serious implications for the data-based modeling, as they place constraints on the accuracy of tail magnetic configurations to be derived for specific events using data of multi-spacecraft missions, e.g. such as THEMIS.

    Positron annihilation lifetime spectroscopy (PALS) provides a direct measurement of the free volume void sizes in polymers and biological systems. This free volume is critical in explaining and understanding physical and mechanical properties of polymers. Moreover, PALS has been recently proposed as a potential tool in detecting cancer at early stages, probing the differences in the subnanometer scale free volume voids between cancerous/healthy skin samples of the same patient. Despite several investigations on free volume in complex cancerous tissues, no positron annihilation studies of living cancer cell cultures have been reported. We demonstrate that PALS can be applied to the study in human living 3D cell cultures. The technique is also capable to detect atomic scale changes in the size of the free volume voids due to the biological responses to TGF-β. PALS may be developed to characterize the effect of different culture conditions in the free volume voids of cells grown in vitro.

  20. The cultural context of patient's autonomy and doctor's duty: passive euthanasia and advance directives in Germany and Israel.

    2010-11-01

    The moral discourse surrounding end-of-life (EoL) decisions is highly complex, and a comparison of Germany and Israel can highlight the impact of cultural factors. The comparison shows interesting differences in how patient's autonomy and doctor's duties are morally and legally related to each other with respect to the withholding and withdrawing of medical treatment in EoL situations. Taking the statements of two national expert ethics committees on EoL in Israel and Germany (and their legal outcome) as an example of this discourse, we describe the similarity of their recommendations and then focus on the differences, including the balancing of ethical principles, what is identified as a problem, what social role professionals play, and the influence of history and religion. The comparison seems to show that Israel is more restrictive in relation to Germany, in contrast with previous bioethical studies in the context of the moral and legal discourse regarding the beginning of life, in which Germany was characterized as far more restrictive. We reflect on the ambivalence of the cultural reasons for this difference and its expression in various dissenting views on passive euthanasia and advance directives, and conclude with a comment on the difficulty in classifying either stance as more or less restrictive.
