1998-01-01

In accordance with the regulations, any factory using ionising radiations is obliged to designate a person having having ability in radiation protection and entrusted with specific missions regarding safety for professional risks. This represents an original measure in comparison with the common rights for work safety. The decree whose became operative on 2 october 1986, about ten years ago and just before the reform of radiation protection standards, it seems important to store in memory the genesis and the goals of this prescription and to present the results.

Agricultural Returns to Labor and the Origins of Work Ethics

OpenAIRE

Fouka, Vasiliki; Schlaepfer, Alain

2017-01-01

We examine the historical determinants of differences in preferences for work across societies today. Our hypothesis is that a society’s work ethic depends on the role that labor has played in it historically, as an input in agricultural production: societies that have for centuries depended on the cultivation of crops with high returns to labor effort will work longer hours and develop a preference for working hard. We formalize this prediction in the context of a model of endogenous prefere...

Working memory benefits creative insight, musical improvisation, and original ideation through maintained task-focused attention.

De Dreu, Carsten K W; Nijstad, Bernard A; Baas, Matthijs; Wolsink, Inge; Roskes, Marieke

2012-05-01

Anecdotes from creative eminences suggest that executive control plays an important role in creativity, but scientific evidence is sparse. Invoking the Dual Pathway to Creativity Model, the authors hypothesize that working memory capacity (WMC) relates to creative performance because it enables persistent, focused, and systematic combining of elements and possibilities (persistence). Study 1 indeed showed that under cognitive load, participants performed worse on a creative insight task. Study 2 revealed positive associations between time-on-task and creativity among individuals high but not low in WMC, even after controlling for general intelligence. Study 3 revealed that across trials, semiprofessional cellists performed increasingly more creative improvisations when they had high rather than low WMC. Study 4 showed that WMC predicts original ideation because it allows persistent (rather than flexible) processing. The authors conclude that WMC benefits creativity because it enables the individual to maintain attention focused on the task and prevents undesirable mind wandering.

Climate History and the Modern World

Science.gov (United States)

Riebsame, William E.

H. H. Lamb's latest book on the earth's changing climate is a carefully crafted work covering four areas: the physical basis of climate and climate change, the methods of climate reconstruction, the history of climate since the height of the last glaciation, and the impact of climate on human affairs. The book will be of particular interest to three groups. Atmospheric scientists interested in the long history of climate behavior (but perhaps overwhelmed by Lamb's all-encompassing work on the topic, Climate: Past, Present and Future, vol. II, Methuen, New York), will find Climate History and the Modern World to be a good titration of the fuller work. Scientists in other fields, including social scientists grappling with issues of climate-society interaction, will find the book a good entree into the field. Finally, Lamb himself suggests that the book will be useful to resource managers and other decision makers trying to avoid negative climate impacts. With this last audience in mind, no doubt, Lamb has chosen a style that eschews extensive footnoting and references (though sufficient citations are included to lead to further information). This works quite well and seems reasonable in view of his carefully documented previous writings.

2014-12-01

To investigate the extent and socioeconomic distribution of incident diabetes among the Danish working-age population. The Danish National Diabetes Register was linked with socioeconomic and population-based registers covering the entire population. We analysed the 12-year diabetes incidence using multivariate Poisson regression for 2,086,682 people, adjusting for gender, 10-year age groups, main population groups defined by country of origin, and seven socioeconomic groups: professionals, managers, technicians, workers skilled at basic level, unskilled workers, unemployed and pensioners. The crude 12-year incidence of diabetes was 5.8%. The saturated multivariate model, adjusted for gender, age, country of origin and socioeconomic status; showed a relative risk (RR) for diabetes incidence of 1.44 for male (reference: female), 3.95 for the age range of 50-59 years (reference: 30-39 years), 2.07 for unskilled workers (reference: professionals) and 2.15 for people from countries of 'non-Western origin' (reference: Danish origin). Diabetes incidence increases with age, male gender and low socioeconomic status; and also among people from countries of 'non-Western origin'. The results indicate that getting a more senior workforce will substantially increase the proportion of workers with diabetes, especially among already vulnerable groups. © 2014 the Nordic Societies of Public Health.

Revisiting the theoretical basis of the endosymbiotic origin of plastids in the original context of Lynn Margulis on the origin of mitosing, eukaryotic cells.

Science.gov (United States)

Sato, Naoki

2017-12-07

Fifty years ago, Lynn Margulis proposed a comprehensive hypothesis on the origin of eukaryotic cells with an emphasis on the origin of mitosis. This hypothesis postulated that the eukaryotic cell is a composite of different parts as a result of the symbiosis of various different bacteria. In this hypothesis, she integrated previously proposed ideas that mitochondria and chloroplasts were descendants of endosymbionts that originated from aerobic bacteria and blue-green algae (now cyanobacteria), respectively. However, the major part of her hypothesis, which she believed to be original, was the origin of mitosis. The core of her postulate involved a chromosome partition mechanism dependent on DNA-microtubule binding, which originated from a hypothetical centriole-DNA complex, with an ability to replicate. Surprisingly, her complete lack of real experimental works in the cytoskeleton, cell motility, or paleontology did not prevent this 29-year-old junior scientist from assembling archival knowledge and constructing a narrative on the evolution of all organisms. Whether the centriole-DNA complex originated from a spirochete or not was a minor anecdote in this initial postulate. Unfortunately, this hypothesis on the origin of mitosis, which she believed to be a holistic unity, testable by experiments, was entirely refuted. Despite falsification of her original narrative as a whole, her success as a founder of endosymbiotic theory on the origin of mitochondria and chloroplasts is undoubted. We will discuss the reasons for her success in terms of the historical situation in the latter half of the 20th century. Copyright © 2017 Elsevier Ltd. All rights reserved.

Categorizing moving objects into film genres: the effect of animacy attribution, emotional response, and the deviation from non-fiction.

Science.gov (United States)

Visch, Valentijn T; Tan, Ed S

2009-02-01

The reported study follows the footsteps of Heider, and Simmel (1944) [Heider, F., & Simmel, M. (1944). An experimental study of apparent behavior. American Journal of Psychology, 57, 243-249] and Michotte (1946/1963) [Michotte, A. (1963). The perception of causality (T.R. Miles & E. Miles, Trans.). London: Methuen (Original work published 1946)] who demonstrated the role of object movement in attributions of life-likeness to figures. It goes one step further in studying the categorization of film scenes as to genre as a function of object movements. In an animated film scene portraying a chase, movements of the chasing object were systematically varied as to parameters: velocity, efficiency, fluency, detail, and deformation. The object movements were categorized by viewers into genres: non-fiction, comedy, drama, and action. Besides this categorization, viewers rated their animacy attribution and emotional response. Results showed that non-expert viewers were consistent in categorizing the genres according to object movement parameters. The size of its deviation from the unmanipulated movement scene determined the assignment of any target scene to one of the fiction genres: small and moderate deviations resulted in categorization as drama and action, and large deviations as comedy. The results suggest that genre classification is achieved by, at least, three distinct cognitive processes: (a) animacy attribution, which influences the fiction versus non-fiction classification; (b) emotional responses, which influences the classification of a specific fiction genre; and (c) the amount of deviation from reality, at least with regard to movements.

Conceptualizing the origin of life in terms of evolution

Science.gov (United States)

Takeuchi, N.; Hogeweg, P.; Kaneko, K.

2017-11-01

In this opinion piece, we discuss how to place evolution in the context of origin-of-life research. Our discussion starts with a popular definition: `life is a self-sustained chemical system capable of undergoing Darwinian evolution'. According to this definition, the origin of life is the same as the origin of evolution: evolution is the `end' of the origin of life. This perspective, however, has a limitation, in that the ability of evolution in and of itself is insufficient to explain the origin of life as we know it, as indicated by Spiegelman's and Lincoln and Joyce's experiments. This limitation provokes a crucial question: What conditions are required for replicating systems to evolve into life? From this perspective, the origin of life includes the emergence of life through evolution: evolution is a `means' of the origin of life. After reviewing Eigen's pioneering work on this question, we mention our ongoing work suggesting that a key condition might be conflicting multi-level evolution. Taken together, there are thus two questions regarding the origin of life: how evolution gets started, and how evolution produces life. Evolution is, therefore, at the centre of the origin of life, where the two lines of enquiry must meet. This article is part of the themed issue 'Reconceptualizing the origins of life'.

Origins of Inner Solar Systems

Science.gov (United States)

Dawson, Rebekah Ilene

2017-06-01

Over the past couple decades, thousands of extra-solar planetshave been discovered orbiting other stars. The exoplanets discovered to date exhibit a wide variety of orbital and compositional properties; most are dramatically different from the planets in our own Solar System. Our classical theories for the origins of planetary systems were crafted to account for the Solar System and fail to account for the diversity of planets now known. We are working to establish a new blueprint for the origin of planetary systems and identify the key parameters of planet formation and evolution that establish the distribution of planetary properties observed today. The new blueprint must account for the properties of planets in inner solar systems, regions of planetary systems closer to their star than Earth’s separation from the Sun and home to most exoplanets detected to data. I present work combining simulations and theory with data analysis and statistics of observed planets to test theories of the origins of inner solars, including hot Jupiters, warm Jupiters, and tightly-packed systems of super-Earths. Ultimately a comprehensive blueprint for planetary systems will allow us to better situate discovered planets in the context of their system’s formation and evolution, important factors in whether the planets may harbor life.

Symbiotic Origin of Aging.

Science.gov (United States)

Greenberg, Edward F; Vatolin, Sergei

2018-06-01

Normally aging cells are characterized by an unbalanced mitochondrial dynamic skewed toward punctate mitochondria. Genetic and pharmacological manipulation of mitochondrial fission/fusion cycles can contribute to both accelerated and decelerated cellular or organismal aging. In this work, we connect these experimental data with the symbiotic theory of mitochondrial origin to generate new insight into the evolutionary origin of aging. Mitochondria originated from autotrophic α-proteobacteria during an ancient endosymbiotic event early in eukaryote evolution. To expand beyond individual host cells, dividing α-proteobacteria initiated host cell lysis; apoptosis is a product of this original symbiont cell lytic exit program. Over the course of evolution, the host eukaryotic cell attenuated the harmful effect of symbiotic proto-mitochondria, and modern mitochondria are now functionally interdependent with eukaryotic cells; they retain their own circular genomes and independent replication timing. In nondividing differentiated or multipotent eukaryotic cells, intracellular mitochondria undergo repeated fission/fusion cycles, favoring fission as organisms age. The discordance between cellular quiescence and mitochondrial proliferation generates intracellular stress, eventually leading to a gradual decline in host cell performance and age-related pathology. Hence, aging evolved from a conflict between maintenance of a quiescent, nonproliferative state and the evolutionarily conserved propagation program driving the life cycle of former symbiotic organisms: mitochondria.

The origins of originality: the neural bases of creative thinking and originality.

Science.gov (United States)

Shamay-Tsoory, S G; Adler, N; Aharon-Peretz, J; Perry, D; Mayseless, N

2011-01-01

Although creativity has been related to prefrontal activity, recent neurological case studies postulate that patients who have left frontal and temporal degeneration involving deterioration of language abilities may actually develop de novo artistic abilities. In this study, we propose a neural and cognitive model according to which a balance between the two hemispheres affects a major aspect of creative cognition, namely, originality. In order to examine the neural basis of originality, that is, the ability to produce statistically infrequent ideas, patients with localized lesions in the medial prefrontal cortex (mPFC), inferior frontal gyrus (IFG), and posterior parietal and temporal cortex (PC), were assessed by two tasks involving divergent thinking and originality. Results indicate that lesions in the mPFC involved the most profound impairment in originality. Furthermore, precise anatomical mapping of lesions indicated that while the extent of lesion in the right mPFC was associated with impaired originality, lesions in the left PC were associated with somewhat elevated levels of originality. A positive correlation between creativity scores and left PC lesions indicated that the larger the lesion is in this area the greater the originality. On the other hand, a negative correlation was observed between originality scores and lesions in the right mPFC. It is concluded that the right mPFC is part of a right fronto-parietal network which is responsible for producing original ideas. It is possible that more linear cognitive processing such as language, mediated by left hemisphere structures interferes with creative cognition. Therefore, lesions in the left hemisphere may be associated with elevated levels of originality. Copyright © 2010 Elsevier Ltd. All rights reserved.

Original article Portfolio working – a psychological analysis of the phenomenon

2014-10-01

Full Text Available Background It turns out from the latest Eurostat data that Poland holds the second place in Europe in terms of the number of so-called portfolio workers, i.e. persons who work for more than one employer. From the psychological point of view, there arises the question regarding the possible determinants of the mentioned phenomenon. Therefore the general purpose of this study is to present the personal and situational indicators of portfolio working. Participants and procedure Two hundred and eighteen portfolio workers and 218 workers employed in one workplace (i.e. monoworkers participated in research using the following set of ‘paper-pencil’ techniques: a self-made survey, the Value Scale by Rokeach, the Formal Characteristics of Behaviour – Temperament Questionnaire by Zawadzki and Strelau, the Masculinity and Femininity Scale by Lipińska-Grobelny and Gorczycka, and the Organizational Climate Questionnaire by Kolb. Results Portfolio working is mainly determined by a number of personal variables (temperamental characteristics, values and spheres of motivation, intensity of masculinity and femininity. A specific role is played by values represented by portfolio workers. The discriminant analysis conducted in groups selected on the basis of working hours indicates that the prediction of participation of the examined persons in the group of portfolio workers with the greatest accuracy appeared in the case of a workload of 48 or more hours, next in the case of a smaller workload up to 47 hours, and finally for the whole group. Conclusions The examination of the phenomenon of portfolio working from the psychological perspective presents an important contribution to the discussion on work and directions of its transformations.

The eukaryotic bell-shaped temporal rate of DNA replication origin firing emanates from a balance between origin activation and passivation.

2018-06-01

The time-dependent rate I(t) of origin firing per length of unreplicated DNA presents a universal bell shape in eukaryotes that has been interpreted as the result of a complex time-evolving interaction between origins and limiting firing factors. Here we show that a normal diffusion of replication fork components towards localized potential replication origins (p-oris) can more simply account for the I(t) universal bell shape, as a consequence of a competition between the origin firing time and the time needed to replicate DNA separating two neighboring p-oris . We predict the I(t) maximal value to be the product of the replication fork speed with the squared p-ori density. We show that this relation is robustly observed in simulations and in experimental data for several eukaryotes. Our work underlines that fork-component recycling and potential origins localization are sufficient spatial ingredients to explain the universality of DNA replication kinetics. © 2018, Arbona et al.

Leonico Tomeo—the First Interpreter and Translater of Aristotle From Original Greek

2010-01-01

In the middle of XV century, in European Renaissance, it was necessary to study the Aristotle in original Greek, because translations from Arab in Latin had caused considerable alterations in the meaning of original texts. This task in the beginning was trusted to Leonico Tomeo, which, not only opened the way for the studying of the Aristotle in original, but himself made important interpretations about philosophic and social problems and gave his arguments about concepts of natural sciences, as for motion, atoms etc. He translated some works of Plato, Aristotle, Ptolemy etc, from the Greek to Latin. The work of Tomeo gave revolutionary results and prepared the way for the scientific method of Galileo, which from Padua, where worked and lived Tomeo and later, Galileo, propagates in all European universities.

Origin of the asteroid belt

International Nuclear Information System (INIS)

Wetherill, G.W.

1989-01-01

Earlier work and concepts relevant to the origin of the asteroid belt are reviewed and considered in the context of the more general question of solar system origin. Several aspects of asteroidal origin by accumulation of smaller bodies have been addressed by new dynamic studies. Numerical and analytical solutions of the dynamical theory of planetesimal accumulation are characterized by a bifurcation into runaway and nonrunaway solutions. The differences in time scales resulting from runaway and nonrunaway growth can be more important than conventional time scale differences determined by heliocentric distances. This introduces new possibilities, e.g., planetary accumulation may be more rapid at the distance of Jupiter than in the asteroid belt, thus permitting Jupiter to control asteroidal growth. Although alternatives must be seriously considered, the most promising approach to asteroidal origin is one in which the initial surface density of the solar nebula varied smoothly between the terrestrial and giant-planet region. In the absence of external perturbations, it is found that runaway growth of excessively large asteroids would then occur on <1 Myr, but fairly modest external perturbations by Jupiter, Saturn or other perturbers, resulting in eccentricities ∼0.01 may quench runaways, truncate asteroidal growth at their present size, and then initiate the necessary loss of asteroidal material by mutual fragmentation

The conditional returns to origin-country human capital among Turkish and Moroccan immigrants in Belgium.

Science.gov (United States)

Kanas, Agnieszka; van Tubergen, Frank

2014-07-01

This study extends the analysis of the economic returns to pre-migration human capital by examining the role of the receiving context, co-ethnic residential concentration, and post-migration investments in human capital. It uses large-scale survey data on Turkish and Moroccan immigrants in Belgium. The analysis demonstrates that regarding employment, Moroccan immigrants, that is, those originating from former French colonies receive larger returns to their origin-country education and work experience in French- vs. Dutch-speaking regions. Other than the positive interaction effect between co-ethnic residential concentration and work experience on employment, there is little evidence that co-ethnic concentration increases the returns to origin-country human capital. Speaking the host-country language facilitates economic returns to origin-country work experience. Conversely, immigrants who acquire host-country credentials and work experience receive lower returns to origin-country education and experience, suggesting that, at least among low-skilled immigrants, pre- and post-migration human capital substitute rather than complement each other.

Symbiosis and the origin of eukaryotic motility

Science.gov (United States)

Margulis, L.; Hinkle, G.

1991-01-01

Ongoing work to test the hypothesis of the origin of eukaryotic cell organelles by microbial symbioses is discussed. Because of the widespread acceptance of the serial endosymbiotic theory (SET) of the origin of plastids and mitochondria, the idea of the symbiotic origin of the centrioles and axonemes for spirochete bacteria motility symbiosis was tested. Intracellular microtubular systems are purported to derive from symbiotic associations between ancestral eukaryotic cells and motile bacteria. Four lines of approach to this problem are being pursued: (1) cloning the gene of a tubulin-like protein discovered in Spirocheata bajacaliforniesis; (2) seeking axoneme proteins in spirochets by antibody cross-reaction; (3) attempting to cultivate larger, free-living spirochetes; and (4) studying in detail spirochetes (e.g., Cristispira) symbiotic with marine animals. Other aspects of the investigation are presented.

2008-01-01

Representation and reconstruction of data obtained by emission tomography scanners are challenging due to high noise levels in the data.

Generating original ideas: The neural underpinning of originality.

Mayseless, Naama; Eran, Ayelet; Shamay-Tsoory, Simone G

One of the key aspects of creativity is the ability to produce original ideas. Originality is defined in terms of the novelty and rarity of an idea and is measured by the infrequency of the idea compared to other ideas. In the current study we focused on divergent thinking (DT) - the ability to produce many alternate ideas - and assessed the neural pathways associated with originality. Considering that generation of original ideas involves both the ability to generate new associations and the ability to overcome automatic common responses, we hypothesized that originality would be associated with activations in regions related to associative thinking, including areas of the default mode network (DMN) such as medial prefrontal areas, as well as with areas involved in cognitive control and inhibition. Thirty participants were scanned while performing a DT task that required the generation of original uses for common objects. The results indicate that the ability to produce original ideas is mediated by activity in several regions that are part of the DMN including the medial prefrontal cortex (mPFC) and the posterior cingulate cortex (PCC). Furthermore, individuals who are more original exhibited enhanced activation in the ventral anterior cingulate cortex (vACC), which was also positively coupled with activity in the left occipital-temporal area. These results are in line with the dual model of creativity, according to which original ideas are a product of the interaction between a system that generates ideas and a control system that evaluates these ideas.

Originality and the PhD: what is it and how can it be demonstrated?

Science.gov (United States)

Gill, Paul; Dolan, Gina

2015-07-01

To explore the concept of originality in doctoral research and outline ways in which doctoral candidates can begin to identify, formulate and articulate their individual contributions to knowledge. Originality is a major feature of doctoral research but considerable confusion exists regarding what can and cannot constitute originality in the PhD and how the contribution to knowledge can be demonstrated clearly. This is a discussion paper. A review of relevant, published literature relating to originality in the PhD. Many doctoral candidates merely outline why they believe their work to be original, instead of demonstrating critically how and in what way their research makes a meaningful contribution to the body of knowledge. The concept of originality in the PhD is complex and multi-faceted. Identifying and conveying originality in doctoral research takes considerable time, contemplation and effort. This process is, however, integral to the PhD itself, and the skills acquired are essential for post-doctoral development. A good doctoral thesis should clearly outline the different ways in which the work is original. A succinct, focused, critical appraisal of the specific contribution to knowledge is preferable to an exhaustive list.

On the Issue of Origin of the Yakut Epic Olonkho

Directory of Open Access Journals (Sweden)

Vasiliy Nikolayevich Ivanov

2018-03-01

Full Text Available The issue on the origin of the Yakut heroic epic Olonkho was covered in works in history and ethnography of the Yakuts back in the 19th century, for instance, in the famous monograph Yakuts. Experience of ethnographic research by a Polish exile V.L. Seroshevskiy (1896. Since that time, this issue was interesting for many, but no special monograph research has been done yet. Currently, the issue of Olonkho origin is gaining special scientific and general cultural significance, as on November 25, 2005 the Yakut heroic epic Olonkho according to the historical decision of UNESCO was granted the high status “Masterpiece of oral and non-material heritage of humanity”. The Yakut epic is a part of the multicomponent epic creative work of the Turkic nations but it was the only one to get such a high international recognition. This paper aims to revive the scientific interest to the issue of the Yakut epic’s genesis. To date, some rich source-related and historiographical material has been accumulated for broader generalizations – the main point is that the Yakut epic is becoming an important object of comparative historical analysis of the origin of all Turkic epics. The thing is that epic researchers admit that almost a thousand years of existence isolated from the whole Turkic world in the North-East of Asia kept many archaic features of the epics of the ancient ancestors – natives of Central Asia and Southern Siberia. It became clear that Olonkho origin is organically linked with the ethnic history of its nation.The paper follows this comprehensive process reflected in works by archeologists, ethnographers, historians and linguists. Their latest achievements are impressive, bringing a lot of novelty into the conventional views of origins and development of the Yakut epic. The paper attempts to specify that novelty and rationalize the idea that time has come to introduce that novelty into science to solve the long-standing issue of origin of

The Really Real, Authentic, Original Shakespeare

Directory of Open Access Journals (Sweden)

Kostihova Marcela

2016-06-01

Full Text Available This essay considers the question of how original/new interpretations help redefine (or reify the original/old perception of Shakespeare and the work its cultural capital performs, demonstrating the inherent impossibility of reconciling an “original” Shakespeare with contemporary performances of his plays through a reading of Twelfth Night, and address some of the ideological implications of trying to conflate the two. It then takes a detour into contemporary marketing and consumer-psychology literature to explore the crucial roles which the concepts of “authenticity” and “originality” have come to play in contemporary consumer culture, circling back to Shakespeare, to ruminate on the implications of the use of his cultural capital as an ultimate positional good in the 21st century.

Question 1: Origin of Life and the Living State

Kauffman, Stuart

2007-10-01

The aim of this article is to discuss four topics: First, the origin of molecular reproduction. Second, the origin of agency the capacity of a system to act on its own behalf. Agency is a stunning feature of human and some wider range of life. Third, to discuss a still poorly articulated feature of life noticed by the philosopher Immanuel Kant over 200 years ago: A self propagating organization of process. We have no theory for this aspect of life, yet it is central to life. Fourth, I will discuss constraints, as in Schroedinger’s aperiodic crystal (Schroedinger E, What is life? The physical aspect of the living cell, 1944), as information, part of the total non-equilibrium union of matter, energy, work, work cycles, constraints, and information that appear to comprise the living state.

The origins of medical physics.

Science.gov (United States)

Duck, Francis A

2014-06-01

The historical origins of medical physics are traced from the first use of weighing as a means of monitoring health by Sanctorius in the early seventeenth century to the emergence of radiology, phototherapy and electrotherapy at the end of the nineteenth century. The origins of biomechanics, due to Borelli, and of medical electricity following Musschenbroek's report of the Leyden Jar, are included. Medical physics emerged as a separate academic discipline in France at the time of the Revolution, with Jean Hallé as its first professor. Physiological physics flowered in Germany during the mid-nineteenth century, led by the work of Adolf Fick. The introduction of the term medical physics into English by Neil Arnott failed to accelerate its acceptance in Britain or the USA. Contributions from Newton, Euler, Bernoulli, Nollet, Matteucci, Pelletan, Gavarret, d'Arsonval, Finsen, Röntgen and others are noted. There are many origins of medical physics, stemming from the many intersections between physics and medicine. Overall, the early nineteenth-century definition of medical physics still holds today: 'Physics applied to the knowledge of the human body, to its preservation and to the cure of its illnesses'.

Widening access to medicine may improve general practitioner recruitment in deprived and rural communities: survey of GP origins and current place of work.

Science.gov (United States)

Dowell, J; Norbury, M; Steven, K; Guthrie, B

2015-10-01

Widening access to medicine in the UK is a recalcitrant problem of increasing political importance, with associated strong social justice arguments but without clear evidence of impact on service delivery. Evidence from the United States suggests that widening access may enhance care to underserved communities. Additionally, rural origin has been demonstrated to be the factor most strongly associated with rural practice. However the evidence regarding socio-economic and rural background and subsequent practice locations in the UK has not been explored. The aim of this study was to investigate the association between general practitioners' (GPs) socio-economic and rural background at application to medical school and demographic characteristics of their current practice. The study design was a cross-sectional email survey of general practitioners practising in Scotland. Socio-economic status of GPs at application to medical school was assessed using the self-coded National Statistics Socio-Economic Classification. UK postcode at application was used to define urban-rural location. Current practice deprivation and remoteness was measured using NHS Scotland defined measures based on registered patients' postcodes. A survey was sent to 2050 Scottish GPs with a valid accessible email address, with 801 (41.5 %) responding. GPs whose parents had semi-routine or routine occupations had 4.3 times the odds of working in a deprived practice compared to those with parents from managerial and professional occupations (95 % CI 1.8-10.2, p = 0.001). GPs from remote and rural Scottish backgrounds were more likely to work in remote Scottish practices, as were GPs originating from other UK countries. This study showed that childhood background is associated with the population GPs subsequently serve, implying that widening access may positively affect service delivery in addition to any social justice rationale. Longitudinal research is needed to explore this association and the

In this work we analyze constrained superfields in supersymmetry and supergravity. We propose a constraint that, in combination with the constrained goldstino multiplet, consistently removes any selected component from a generic superfield. We also describe its origin, providing the operators whose equations of motion lead to the decoupling of such components. We illustrate our proposal by means of various examples and show how known constraints can be reproduced by our method.

Working in rural areas – the experiences of Umthombo Youth Development Foundation graduates

Andrew J. Ross

2014-12-01

Full Text Available Background: Recruiting and retaining healthcare professionals (HCPs for rural areas is challenging throughout the world. Although rural origin HCPs have been identified as being the most likely to work in rural areas, only a small number of rural-origin South African scholars are trained as HCPs each year and many do not return to work in rural areas. Aim: The aim of this article was to present the experiences of rural-origin HCPs who returned to work in a rural area after graduation. Setting: Umthombo Youth Development Foundation has been running an innovating rurally-based scholarship scheme since 1999. By December 2013, 184 students supported by the scheme had graduated and all had returned to work in a rural area for a period of time. Methods: This was a qualitative study using a life history methodology to explore the educational experience of six rural-origin HCPs working in rural areas. Results: The four themes that emerged from the data were: (1 contribution to service delivery; (2 professional development (3 the challenges and frustrations of working in rural hospitals; and (4 the impact of working as an HCP. Conclusion: Rural-origin HCPs are willing to return and work in rural areas. However, context and content factors need to be addressed if a work-back scholarship scheme is to be along-term strategy for the recruitment and retention of HCPs.

Work engagement is a positive work-related state of fulfillment characterized by vigor, dedication, and absorption. Previous studies have operationalized the construct through development of the Utrecht Work Engagement Scale. Apart from the original three-factor 17-item version of the instrument (UWES-17), there exists a nine-item shortened revised version (UWES-9). The current study explored the psychometric properties of the Chinese version of the Utrecht Work Engagement Scale in terms of factorial validity, scale reliability, descriptive statistics, and construct validity. A cross-sectional questionnaire survey was conducted in 2009 among 992 workers from over 30 elderly service units in Hong Kong. Confirmatory factor analyses revealed a better fit for the three-factor model of the UWES-9 than the UWES-17 and the one-factor model of the UWES-9. The three factors showed acceptable internal consistency and strong correlations with factors in the original versions. Engagement was negatively associated with perceived stress and burnout while positively with age and holistic care climate. The UWES-9 demonstrates adequate psychometric properties, supporting its use in future research in the Chinese context.

How and why multiple MCMs are loaded at origins of DNA replication.

Science.gov (United States)

Das, Shankar P; Rhind, Nicholas

2016-07-01

Recent work suggests that DNA replication origins are regulated by the number of multiple mini-chromosome maintenance (MCM) complexes loaded. Origins are defined by the loading of MCM - the replicative helicase which initiates DNA replication and replication kinetics determined by origin's location and firing times. However, activation of MCM is heterogeneous; different origins firing at different times in different cells. Also, more MCMs are loaded in G1 than are used in S phase. These aspects of MCM biology are explained by the observation that multiple MCMs are loaded at origins. Having more MCMs at early origins makes them more likely to fire, effecting differences in origin efficiency that define replication timing. Nonetheless, multiple MCM loading raises new questions, such as how they are loaded, where these MCMs reside at origins, and how their presence affects replication timing. In this review, we address these questions and discuss future avenues of research. © 2016 WILEY Periodicals, Inc.

Chiral Gold Nanoclusters: Atomic Level Origins of Chirality.

Science.gov (United States)

Zeng, Chenjie; Jin, Rongchao

2017-08-04

Chiral nanomaterials have received wide interest in many areas, but the exact origin of chirality at the atomic level remains elusive in many cases. With recent significant progress in atomically precise gold nanoclusters (e.g., thiolate-protected Au n (SR) m ), several origins of chirality have been unveiled based upon atomic structures determined by using single-crystal X-ray crystallography. The reported chiral Au n (SR) m structures explicitly reveal a predominant origin of chirality that arises from the Au-S chiral patterns at the metal-ligand interface, as opposed to the chiral arrangement of metal atoms in the inner core (i.e. kernel). In addition, chirality can also be introduced by a chiral ligand, manifested in the circular dichroism response from metal-based electronic transitions other than the ligand's own transition(s). Lastly, the chiral arrangement of carbon tails of the ligands has also been discovered in a very recent work on chiral Au 133 (SR) 52 and Au 246 (SR) 80 nanoclusters. Overall, the origins of chirality discovered in Au n (SR) m nanoclusters may provide models for the understanding of chirality origins in other types of nanomaterials and also constitute the basis for the development of various applications of chiral nanoparticles. © 2017 Wiley-VCH Verlag GmbH & Co.

Red Assembly: the work remains

Full Text Available This issue of Kronos is dedicated to Terry Flynn, assistant curator at the Ann Bryant Art Gallery, who was instrumental in the successful installing of 'Red Assembly' there in 2015. Friend, colleague, artist and inspiration. Hamba Kahle. The work that emerged from the encounter with Red, an art installation by Simon Gush and his collaborators, in the workshop 'Red Assembly', held in East London in August 2015, is assembled here in Kronos, the journal of southern African histories based at the University of the Western Cape, and previously in parallax, the cultural studies journal based at the University of Leeds published in May 2016. What is presented there and here is not simply more work, work that follows, or even additional works. Rather, it is the work that arises as a response to a question that structured our entire project: does Red, now also installed in these two journals, have the potential to call the discourse of history into question? This article responds to this question through several pairings: theft - gift; copy - rights; time - history; kronos - chronos. Here we identify a reversal in this installation of the gift into the commodity, and another with regard to conventional historical narratives which privilege the search for sources and origins. A difference between (the historian's search for origination and (the artist's originality becomes visible in a conversation between and over the historic and the artistic that does not simply try to rescue History by means of the work of art. It is in this sense that we invite the displacements, detours, and paths made possible through Simon Gush's Red, the 'Red Assembly' workshop and the work/gift of installation and parallaxing. To gesture beyond 'histories' is the provocation to which art is neither cause nor effect. Thinking with the work of art, that is, grasping thought in the working of art, has extended the sense of history's limit and the way the limit of history is

Extractable Work from Correlations

Directory of Open Access Journals (Sweden)

Martí Perarnau-Llobet

2015-10-01

Full Text Available Work and quantum correlations are two fundamental resources in thermodynamics and quantum information theory. In this work, we study how to use correlations among quantum systems to optimally store work. We analyze this question for isolated quantum ensembles, where the work can be naturally divided into two contributions: a local contribution from each system and a global contribution originating from correlations among systems. We focus on the latter and consider quantum systems that are locally thermal, thus from which any extractable work can only come from correlations. We compute the maximum extractable work for general entangled states, separable states, and states with fixed entropy. Our results show that while entanglement gives an advantage for small quantum ensembles, this gain vanishes for a large number of systems.

2010-02-10

The determination of the geographical origin of cocoa used to produce chocolate has been assessed through the analysis of the volatile compounds of chocolate samples. The analysis of the volatile content and their statistical processing by multivariate analyses tended to form independent groups for both Africa and Madagascar, even if some of the chocolate samples analyzed appeared in a mixed zone together with those from America. This analysis also allowed a clear separation between Caribbean chocolates and those from other origins. Height compounds (such as linalool or (E,E)-2,4-decadienal) characteristic of chocolate's different geographical origins were also identified. The method described in this work (hydrodistillation, GC analysis, and statistic treatment) may improve the control of the geographical origin of chocolate during its long production process.

Darwin at Orchis Bank: Selection after the Origin.

Science.gov (United States)

Tabb, Kathryn

2016-02-01

Darwin's first publication after the Origin of Species was a volume on orchids that expanded on the theory of adaptation through natural selection introduced in his opus. Here I argue that On the Various Contrivances by which British and Foreign Orchids are Fertilised by Insects (1862) is not merely an empirical confirmation of his theory. In response to immediate criticisms of his metaphor of natural selection, Darwin uses Orchids to present adaptation as the result of innumerable natural laws, rather than discrete acts analogous to conscious choices. The means of selection among polliniferous plants cannot be neatly classed under the Origin's categories of artificial, natural, or sexual selection. Along with Darwin's exploration of sexual selection in his later works, Orchids serves to undo the restrictive metaphor so firmly established by the Origin and to win over those of Darwin's contemporaries who were committed advocates of natural law but suspicious of evolution by natural selection.

Toward the assessment of the work-family interface: Validation of the Slovenian versions of work-family conflict and work-family enrichment scales

Directory of Open Access Journals (Sweden)

Sara Tement

2010-11-01

Full Text Available Research on the work-family interface has gained importance especially because of the changing composition of the working population and the rapidly changing working environment worldwide. However, there are no appropriate questionnaires available that would address negative and positive experiences of the work-family interface. Therefore, a study has been conducted in order to validate two existing scales measuring work-family conflict and work-family enrichment. The dimensionality, item adequacy, reliability, and construct validity were addressed by means of a sample of 214 employees from Slovenian enterprises and institutions. The results for the Slovenian scales confirmed the multiple dimensions of the original versions. Support was also found for acceptable reliability and construct validity of the two scales. Although some limitations were noticed, the scales represent an important step in examining the work-family interface of the Slovenian workforce.

Shift work, long working hours and preterm birth: a systematic review and meta-analysis.

Specific physical activities or working conditions are suspected for increasing the risk of preterm birth (PTB). The aim of this meta-analysis is to review and summarize the pre-existing evidence on the effect of shift work or long working hours on the risk of PTB. We conducted a systematic search in MEDLINE and EMBASE (1990-2013) for observational and intervention studies with original data. We only included articles that met our specific criteria for language, exposure, outcome, data collection and original data that were of at least of moderate quality. The data of the included studies were pooled. Eight high-quality studies and eight moderate-quality studies were included in the meta-analysis. In these studies, no clear or statistically significant relationship between shift work and PTB was found. The summary estimate OR for performing shift work during pregnancy and the risk of PTB were 1.04 (95% CI 0.90-1.20). For long working hours during pregnancy, the summary estimate OR was 1.25 (95% CI 1.01-1.54), indicating a marginally statistically significant relationship but an only slightly elevated risk. Although in many of the included studies a positive association between long working hours and PTB was seen this did reach only marginal statistical significance. In the studies included in this review, working in shifts or in night shifts during pregnancy was not significantly associated with an increased risk for PTB. For both risk factors, due to the lack of high-quality studies focusing on the risks per trimester, in particular the third trimester, a firm conclusion about an association cannot be stated.

He comments results obtained by another researcher related to the tracing of radionuclide origin in the Rhone river, and reports activity level measurements performed within French waters (and more particularly in the Rhone river, and in irrigation canals). He proposes a focus of the behaviour and coefficients of solid/solution distribution in the case of the Rhone river and of Fukushima water streams. He briefly comments the radiological quality of drinking waters (exposure to radiations and regulation, case of the Rhone river and of neighbouring coastal rivers). He discusses the flow of radionuclides towards the sea environment and proposes some material assessments. Results of various researches performed by the author or made under his supervision are discussed. They relate to extreme events (impact of floods on contaminant transport), to storages and sedimentary archives, and to the use of tritium and carbon 14 to study long cycles. Research perspectives are then discussed on various issues: consequences of typhoons and roles of organic particles in the transport or transfer of radioactivity in the case of Fukushima rivers, estuarine reactions [fr

Cosmic Origins Program Annual Technology Report

Pham, Bruce Thai; Neff, Susan Gale

2015-01-01

What is the Cosmic Origins (COR) Program? From ancient times, humans have looked up at the night sky and wondered: Are we alone? How did the universe come to be? How does the universe work? COR focuses on the second question. Scientists investigating this broad theme seek to understand the origin and evolution of the universe from the Big Bang to the present day, determining how the expanding universe grew into a grand cosmic web of dark matter enmeshed with galaxies and pristine gas, forming, merging, and evolving over time. COR also seeks to understand how stars and planets form from clouds in these galaxies to create the heavy elements that are essential to life starting with the first generation of stars to seed the universe, and continuing through the birth and eventual death of all subsequent generations of stars. The COR Programs purview includes the majority of the field known as astronomy, from antiquity to the present.

Origin,

Directory of Open Access Journals (Sweden)

Artur de Vargas Giorgi

2011-02-01

Full Text Available This essay tightens the “origin” concept, its manifestation through puzzles and their relationship to techniques of reproduction. Contrary to the hegemonic critique of aesthetic and cultural objects – critique that, settled on the appearance and notions of identity, tradition, canon, etc., undervalues the reproductions of "originals" –, the aim is to deliver these objects from formal hierarchization dispositives, that is, release them of what is ideal and positively imposed, so that the reproducibility is potentiated as producer of singularities, of apparitions. The effort is to keep the undecided character of puzzles (bodies, texts, images in which the origin is manifest, so that the logic of the spectacle is reverted into sense opening, instance in which the aesthetic becomes a “performance” before contemporary complexity. With the reproducibility, an origin survives in passage: continually restored, but incomplete, present in trace, in absence.

[Night work, shift work: Breast cancer risk factor?].

Science.gov (United States)

Benabu, J-C; Stoll, F; Gonzalez, M; Mathelin, C

2015-12-01

The aim of this review was to determine the link between night/shift work and breast cancer. The analysed articles were taken from the PUBMED database between 1996 and 2015. The keywords used were "breast cancer risk", "night work" and "shift work". In total, 25 articles were selected. Night/shift workers are more at risk to develop a breast cancer (relative risk (RR) between 1.09; 95% CI: 1.02-1.20 and 1.48; 95% CI: 1.36-1.61 in the meta-analyses). However, this risk is not found by some cohort and case-control studies. The circadian rhythm disruption, responsible of disorderliness of melatonin secretion, could be one of the mechanisms involved in the increase of that risk. Hormonal status of night/shift workers, their geographic origin, their lifestyle and their vitamin D deficiency appear as other mechanisms potentially responsible for increased risk of cancer in this professional population. Moreover, a dose-effect connection may exist, with an increase of the risk with the number of years of night/shift work. Night/shift work is associated with a moderate increased risk of breast cancer, especially among women who worked over 20 years. Recommendations concerning the breast monitoring in this population could be diffused. The benefit of melatonin supplementation remains to be assessed. Copyright © 2015. Published by Elsevier SAS.

2010-11-05

With the globalization of occupational health psychology, more and more researchers are interested in applying employee well-being like work engagement (i.e., a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption) to diverse populations. Accurate measurement contributes to our further understanding and to the generalizability of the concept of work engagement across different cultures. The present study investigated the measurement accuracy of the Japanese and the original Dutch versions of the Utrecht Work Engagement Scale (9-item version, UWES-9) and the comparability of this scale between both countries. Item Response Theory (IRT) was applied to the data from Japan (N = 2,339) and the Netherlands (N = 13,406). Reliability of the scale was evaluated at various levels of the latent trait (i.e., work engagement) based the test information function (TIF) and the standard error of measurement (SEM). The Japanese version had difficulty in differentiating respondents with extremely low work engagement, whereas the original Dutch version had difficulty in differentiating respondents with high work engagement. The measurement accuracy of both versions was not similar. Suppression of positive affect among Japanese people and self-enhancement (the general sensitivity to positive self-relevant information) among Dutch people may have caused decreased measurement accuracy. Hence, we should be cautious when interpreting low engagement scores among Japanese as well as high engagement scores among western employees.

Multiple determinants controlling activation of yeast replication origins late in S phase.

Friedman, K L; Diller, J D; Ferguson, B M; Nyland, S V; Brewer, B J; Fangman, W L

1996-07-01

Analysis of a 131-kb segment of the left arm of yeast chromosome XIV beginning 157 kb from the telomere reveals four highly active origins of replication that initiate replication late in S phase. Previous work has shown that telomeres act as determinants for late origin activation. However, at least two of the chromosome XIV origins maintain their late activation time when located on large circular plasmids, indicating that late replication is independent of telomeres. Analysis of the replication time of plasmid derivatives containing varying amounts of chromosome XIV DNA show that a minimum of three chromosomal elements, distinct from each tested origin, contribute to late activation time. These late determinants are functionally equivalent, because duplication of one set of contributing sequences can compensate for the removal of another set. Furthermore, insertion of an origin that is normally early activated into this domain results in a shift to late activation, suggesting that the chromosome XIV origins are not unique in their ability to respond to the late determinants.

Fungi identify the geographic origin of dust samples.

Directory of Open Access Journals (Sweden)

Neal S Grantham

Full Text Available There is a long history of archaeologists and forensic scientists using pollen found in a dust sample to identify its geographic origin or history. Such palynological approaches have important limitations as they require time-consuming identification of pollen grains, a priori knowledge of plant species distributions, and a sufficient diversity of pollen types to permit spatial or temporal identification. We demonstrate an alternative approach based on DNA sequencing analyses of the fungal diversity found in dust samples. Using nearly 1,000 dust samples collected from across the continental U.S., our analyses identify up to 40,000 fungal taxa from these samples, many of which exhibit a high degree of geographic endemism. We develop a statistical learning algorithm via discriminant analysis that exploits this geographic endemicity in the fungal diversity to correctly identify samples to within a few hundred kilometers of their geographic origin with high probability. In addition, our statistical approach provides a measure of certainty for each prediction, in contrast with current palynology methods that are almost always based on expert opinion and devoid of statistical inference. Fungal taxa found in dust samples can therefore be used to identify the origin of that dust and, more importantly, we can quantify our degree of certainty that a sample originated in a particular place. This work opens up a new approach to forensic biology that could be used by scientists to identify the origin of dust or soil samples found on objects, clothing, or archaeological artifacts.

Navigating between two cultures: Immigrants' gender attitudes toward working women

Directory of Open Access Journals (Sweden)

Léa Pessin

2018-03-01

Full Text Available Background: Gender attitudes toward women's employment are of particular importance because they positively influence gender-equal outcomes in the labor market. Our understanding of the mechanisms that promote egalitarian gender attitudes among immigrants, however, remains limited. Objective: By studying first- and second-generation immigrants from multiple origins and living in different countries, this article seeks to explain under what conditions the prevalent cultural attitudes toward gender roles at the origin and destination influence immigrants' gender attitudes. We address three main research questions. First, does the country-of-origin gender ideology influence immigrants' views toward working women? Second, does the country-of-destination gender ideology influence immigrants' views toward working women? And third, are these relationships moderated by (1 the immigrant generation; (2 the age at arrival in the country of destination; (3 the length of residence at the destination? Methods: Using data from the European Social Survey, we model immigrants' gender attitudes toward working women by using linear cross-classified models to account for clustering into the country of origin and destination. Results: The results highlight the importance of the context of early socialization in shaping immigrants' gender attitudes. First-generation immigrants, and more specifically adult migrants, hold gender attitudes that reflect more strongly the country of origin's gender culture. In contrast, the positive association between gender ideology at destination and immigrants' gender attitudes is stronger among second-generation immigrants and child migrants. Contribution: We add to the literature on gender ideology formation by analyzing the influence of gender ideology at the origin and destination levels on the gender attitudes of immigrants from 96 countries of origin and residing across 32 countries of destination.

A discussion on the origin of quantum probabilities

Holik, Federico; Sáenz, Manuel; Plastino, Angel

2014-01-01

We study the origin of quantum probabilities as arising from non-Boolean propositional-operational structures. We apply the method developed by Cox to non distributive lattices and develop an alternative formulation of non-Kolmogorovian probability measures for quantum mechanics. By generalizing the method presented in previous works, we outline a general framework for the deduction of probabilities in general propositional structures represented by lattices (including the non-distributive case). -- Highlights: •Several recent works use a derivation similar to that of R.T. Cox to obtain quantum probabilities. •We apply Cox’s method to the lattice of subspaces of the Hilbert space. •We obtain a derivation of quantum probabilities which includes mixed states. •The method presented in this work is susceptible to generalization. •It includes quantum mechanics and classical mechanics as particular cases

2016-09-01

Twenty-one almond samples from three different geographical origins (Sicily, Spain and California) were investigated by determining minerals and fatty acids compositions. Data were used to discriminate by chemometry almond origin by linear discriminant analysis. With respect to previous PCA profiling studies, this work provides a simpler analytical protocol for the identification of almonds geographical origin. Classification by using mineral contents data only was correct in 77% of the samples, while, by using fatty acid profiles, the percentages of samples correctly classified reached 82%. The coupling of mineral contents and fatty acid profiles lead to an increased efficiency of the classification with 87% of samples correctly classified.

A Data-origin Authentication Protocol Based on ONOS Cluster

Full Text Available This paper is aim to propose a data-origin authentication protocol based on ONOS cluster. ONOS is a SDN controller which can work under a distributed environment. However, the security of an ONOS cluster is seldom considered, and the communication in an ONOS cluster may suffer from lots of security threats. In this paper, we used a two-tier self-renewable hash chain for identity authentication and data-origin authentication. We analyse the security and overhead of our proposal and made a comparison with current security measure. It showed that with the help of our proposal, communication in an ONOS cluster could be protected from identity forging, replay attacks, data tampering, MITM attacks and repudiation, also the computational overhead would decrease apparently.

We present a case of a 56-year-old male electrician who was admitted to the hospital with atrial fibrillation, atypical chest pain and dyspnea. He gave a history that on the morning he had working for almost 4 hours carrying out various activities with considerable physical effort. After cardioversion, conventional coronary angiography revealed a suspect of single coronary vessel (SCA) arising from the right sinus of Valsalva. The patient underwent multislice computed tomography that showed a SCA arising from the right sinus Valsalva and dividing in Right Coronary Artery (RCA) and Left Main coronary artery (LM). The finding of posterior course of the LM without atherosclerotic has proved crucial for the expression of an opinion of working capacity even with limitation.

Bilateral subclavian origin of the bronchial arteries combined with absence of other origins.

Jie, Bing; Sun, Xi-Wen; Yu, Dong; Jiang, Sen

2014-08-01

There are numerous anatomical variations of the sites of origin of the bronchial arteries (BAs). A subclavian origin of a BA involves an aberrant artery that originates from the subclavian artery (SCA) or its branches. However, the aberrant artery usually originates directly from the SCA, and an SCA-origin BA arising from the branches of the SCA is rare. We herein present an extremely rare case of a right BA arising from the ipsilateral costocervical trunk, and a left BA arising from the ipsilateral thyrocervical trunk, in the absence of other origins of the BA. This anatomical variation was detected during pretherapeutic evaluation by multidetector-row computed tomography and confirmed by selective angiography. Recognition of these anatomic variations is important to surgical, diagnostic, and interventional radiologic procedures in the thorax.

Dark chocolate acceptability: influence of cocoa origin and processing conditions.

Torres-Moreno, Miriam; Tarrega, Amparo; Costell, Elvira; Blanch, Consol

Chocolate properties can vary depending on cocoa origin, composition and manufacturing procedure, which affect consumer acceptability. The aim of this work was to study the effect of two cocoa origins (Ghana and Ecuador) and two processing conditions (roasting time and conching time) on dark chocolate acceptability. Overall acceptability and acceptability for different attributes (colour, flavour, odour and texture) were evaluated by 95 consumers. Differences in acceptability among dark chocolates were mainly related to differences in flavour acceptability. The use of a long roasting time lowered chocolate acceptability in Ghanaian samples while it had no effect on acceptability of Ecuadorian chocolates. This response was observed for most consumers (two subgroups with different frequency consumption of dark chocolate). However, for a third group of consumers identified as distinguishers, the most acceptable dark chocolate samples were those produced with specific combinations of roasting time and conching time for each of the cocoa geographical origin considered. To produce dark chocolates from a single origin it is important to know the target market preferences and to select the appropriate roasting and conching conditions.

Understanding original antigenic sin in influenza with a dynamical system.

Science.gov (United States)

Pan, Keyao

2011-01-01

Original antigenic sin is the phenomenon in which prior exposure to an antigen leads to a subsequent suboptimal immune response to a related antigen. Immune memory normally allows for an improved and rapid response to antigens previously seen and is the mechanism by which vaccination works. I here develop a dynamical system model of the mechanism of original antigenic sin in influenza, clarifying and explaining the detailed spin-glass treatment of original antigenic sin. The dynamical system describes the viral load, the quantities of healthy and infected epithelial cells, the concentrations of naïve and memory antibodies, and the affinities of naïve and memory antibodies. I give explicit correspondences between the microscopic variables of the spin-glass model and those of the present dynamical system model. The dynamical system model reproduces the phenomenon of original antigenic sin and describes how a competition between different types of B cells compromises the overall effect of immune response. I illustrate the competition between the naïve and the memory antibodies as a function of the antigenic distance between the initial and subsequent antigens. The suboptimal immune response caused by original antigenic sin is observed when the host is exposed to an antigen which has intermediate antigenic distance to a second antigen previously recognized by the host's immune system.

Musical emotions: Functions, origins, evolution

Science.gov (United States)

Perlovsky, Leonid

2010-03-01

Theories of music origins and the role of musical emotions in the mind are reviewed. Most existing theories contradict each other, and cannot explain mechanisms or roles of musical emotions in workings of the mind, nor evolutionary reasons for music origins. Music seems to be an enigma. Nevertheless, a synthesis of cognitive science and mathematical models of the mind has been proposed describing a fundamental role of music in the functioning and evolution of the mind, consciousness, and cultures. The review considers ancient theories of music as well as contemporary theories advanced by leading authors in this field. It addresses one hypothesis that promises to unify the field and proposes a theory of musical origin based on a fundamental role of music in cognition and evolution of consciousness and culture. We consider a split in the vocalizations of proto-humans into two types: one less emotional and more concretely-semantic, evolving into language, and the other preserving emotional connections along with semantic ambiguity, evolving into music. The proposed hypothesis departs from other theories in considering specific mechanisms of the mind-brain, which required the evolution of music parallel with the evolution of cultures and languages. Arguments are reviewed that the evolution of language toward becoming the semantically powerful tool of today required emancipation from emotional encumbrances. The opposite, no less powerful mechanisms required a compensatory evolution of music toward more differentiated and refined emotionality. The need for refined music in the process of cultural evolution is grounded in fundamental mechanisms of the mind. This is why today's human mind and cultures cannot exist without today's music. The reviewed hypothesis gives a basis for future analysis of why different evolutionary paths of languages were paralleled by different evolutionary paths of music. Approaches toward experimental verification of this hypothesis in

Jones, Jennifer D

2006-01-01

While researchers have documented the efficacy of clinical songwriting in music therapy, limited research has been conducted on songs composed by music therapists that address clinical goals. The purpose of this research was to examine the original songwriting practices of music therapists. Professional music therapists (N = 1,364) received a 14-question survey via email asking each to identify client populations and clinical goals addressed by original songs, their length of time in clinical practice, and specifics about their acquisition of songwriting skills. The data collected from 302 completed surveys revealed that respondents who used original songs were most likely to work with children and adolescents in schools or the developmental disability field and wrote songs in order to individualize treatment. Music therapists working with persons over 65 years of age in long term care or assisted living programs were the least likely to use original songs in clinical practice, opting for interventions utilizing the client's familiar music. Most music therapists found songwriting generally easy, but only 37% indicated that they acquired this skill during their undergraduate degree. Additional research on the clinical efficacy of original songs and therapist's compositional processes is needed to identify best practices models for strategic songwriting.

Firstly, the copies which of-ten are considered to be typical museum copies, characterize the strategy for the disseminating relation between original and copy, that is, reproductions, magnets, etc. This strategy implies how copy practices are closely integrated into museum practices in general. Secondly, the supplementing relation between original and copy will be introduced. This strategy frames, for example, artists' citations of other works and forgeries. Both show that copy practices often lead to new originals, in principle, ad infinitum. Thirdly, this leads to the strategy for the displacing relation between original and copy which encompasses, for example, artistic reworkings of other artists' originals and conservatorial restorations. This approach partly ex-cludes the copy and partly displaces the original, while still, unavoidably, referring to the latter. In general, this strategy signifies the latent instability of the origi-nal. Fourthly, the strategy for the informational relation between original and copy will be discussed as it has a vital function in terms of talking about museum originals and copies. This is the strategy which grants the original artifacts their status as museum objects. An informational copy is just as unique as an original object of art, and at the same time, it defines the original and is itself defined by this opposition. Lastly, the strategy for the imagined relation between original and copy follows. This strategy is dependent upon several of the previous approaches, and, in addition, handles signs that exist without explicit originals, as the strategy covers copies referring to originals which have disappeared

Dynamical Origin of the Effective Storage Capacity in the Brain's Working Memory

Science.gov (United States)

Bick, Christian; Rabinovich, Mikhail I.

2009-11-01

The capacity of working memory (WM), a short-term buffer for information in the brain, is limited. We suggest a model for sequential WM that is based upon winnerless competition amongst representations of available informational items. Analytical results for the underlying mathematical model relate WM capacity and relative lateral inhibition in the corresponding neural network. This implies an upper bound for WM capacity, which is, under reasonable neurobiological assumptions, close to the “magical number seven.”

Naturally death-resistant precursor cells revealed as the origin of retinoblastoma

DEFF Research Database (Denmark)

Trinh, Emmanuelle; Lazzerini Denchi, Eros; Helin, Kristian

2004-01-01

The molecular mechanisms and the cell-of-origin leading to retinoblastoma are not well defined. In this issue of Cancer Cell, Bremner and colleagues describe the first inheritable model of retinoblastoma, revealing that loss of the pocket proteins pRb and p107 deregulates cell cycle exit in retinal...... precursors. The authors show that a subset of these precursors contain an inherent resistance to apoptosis, and that while most terminally differentiate, some are likely to acquire additional mutations, leading to tumor formation. Thus, this work defines the cell-of-origin of retinoblastoma and suggests...... that mutations giving increased proliferative capacity are required for retinoblastoma development....

Authentication of Botanical Origin in Herbal Teas by Plastid Noncoding DNA Length Polymorphisms.

Science.gov (United States)

Uncu, Ali Tevfik; Uncu, Ayse Ozgur; Frary, Anne; Doganlar, Sami

2015-07-01

The aim of this study was to develop a DNA barcode assay to authenticate the botanical origin of herbal teas. To reach this aim, we tested the efficiency of a PCR-capillary electrophoresis (PCR-CE) approach on commercial herbal tea samples using two noncoding plastid barcodes, the trnL intron and the intergenic spacer between trnL and trnF. Barcode DNA length polymorphisms proved successful in authenticating the species origin of herbal teas. We verified the validity of our approach by sequencing species-specific barcode amplicons from herbal tea samples. Moreover, we displayed the utility of PCR-CE assays coupled with sequencing to identify the origin of undeclared plant material in herbal tea samples. The PCR-CE assays proposed in this work can be applied as routine tests for the verification of botanical origin in herbal teas and can be extended to authenticate all types of herbal foodstuffs.

Millennials and the World of Work: Experiences in Paid Work During Adolescence.

Science.gov (United States)

Staff, Jeremy; Schulenberg, John E

2010-06-01

PURPOSE: This article considers some important questions faced by youth as they enter and adapt to paid work. We focus on two key questions: (1) how many hours should teenagers work during the school year and (2) what available jobs are desirable? DESIGN/METHODOLOGY/APPROACH: To help answer these questions, we review studies that have examined the effects of early work experiences on academic achievement, positive youth development, and health-risk behaviors. We also draw upon nationally representative data from the Monitoring the Future (MTF) study to illustrate some new findings on youth employment. FINDINGS: Moderate work hours, especially in jobs of higher-quality, are associated with a broad range of positive developmental outcomes. IMPLICATIONS: These questions are not only important to teenagers and their parents, they also reflect key debates among scholars in sociology, developmental psychology, and economics regarding the potential short- and long-term consequences of early work experiences for social development and socioeconomic achievement. ORIGINALITY/VALUE: Although work intensity is an important dimension of adolescent work experience, it is clearly not the only one and we argue that it may not even be the most important one. By focusing on types and qualities of jobs, more can be gained in terms of understanding for whom and under what conditions teenage work does provide benefits for and detriments to youth development.

Diagnosis and treatment principle in Sasang medicine: original symptom

Directory of Open Access Journals (Sweden)

Seungwon Shin

2016-06-01

Full Text Available The purpose of this review was to demonstrate the definition of the original symptom (OS and how it works in medical procedures as to the Sasang medicine based on the Jema Lee's Donguisusebowon (Longevity and Life Preservation in Eastern Medicine. OS is defined as the sum of all clinical information featured by an individual's intrinsic characteristics as Sasangin and health state prior to onset. It is the key factor in the clinical application of Sasang medicine including the diagnosis of constitutional type and Sasang symptomatology because the imbalance of metabolic functions of each Sasangin originates from that. The working principles of the OS and Sasang symptomatology can be summarized as follows. First, clinical information regarding cold or heat intolerance determines the cold or heat pattern of Sasang symptomatology. Another is the present worsening of the severity of Sasang symptomatology by one level as compared with that in the past. Symptoms prior to the onset worsen to a higher level of severity after any disorder breaks out. Finally, the treatment strategy and progress of each Sasangin are determined following the characteristics of the OS. Theoretical and clinical studies should be conducted to show the specific criteria for the diagnosis of Sasang symptomatology in the future.

The origin of chirality in protein amino acids

International Nuclear Information System (INIS)

Chela Flores, J.

1994-03-01

We discuss the origin of the chirality of protein amino acids from the point of view of a phase transition from a racemic mixture into an optically pure state. We assume that Bose-Einstein condensation may act as an amplification mechanism. The originals theory is due to Salam. We suggest a new role for the phase transition. Following Quack we distinguish parity violation of two kinds (de facto and de lege symmetry breaking). While the Salam phase transition corresponds to parity violation of the second kind (de lege), the phase transition we discuss in this work corresponds to parity violation of what we may call a third kind. This is suggested by recent experimental phenomena which correlate chiral symmetry breaking and pattern formation (spontaneous symmetry breaking that separates an initial racemic mixture into right- and left-handed space domains by means of a substrate). Tentative comments are given on the eventual design of possible experiments that may test this new hypothesis. (author). Refs

What is the Cosmic Origins (COR) Program? From ancient times, humans have looked up at the night sky and wondered: Are we alone? How did the universe come to be? How does the universe work? COR focuses on the second question. Scientists investigating this broad theme seek to understand the origin and evolution of the universe from the Big Bang to the present day, determining how the expanding universe grew into a grand cosmic web of dark matter enmeshed with galaxies and pristine gas, forming, merging, and evolving over time. COR also seeks to understand how stars and planets form from clouds in these galaxies to create the heavy elements that are essential to life, starting with the first generation of stars to seed the universe, and continuing through the birth and eventual death of all subsequent generations of stars. The COR Programs purview includes the majority of the field known as astronomy.

The Diagnostic Agreement of Original and Faxed Copies of Electrocardiograms

Sadrihe Hajesmaeel-Gohari

2013-02-01

Full Text Available Background: General practitioners working in remote and rural areas sometimes need consultation with cardiologists. One practical and cost-effective way is transmission of patients’ electrocardiographic images via ordinary fax machine to the cardiologists, but there is an important question that how much agreement exists between the diagnoses made by reading an original electrocardiogram and its copy transmitted via fax.Materials and Methods: In this cross-sectional study, 60 original electrocardiographic images were given to cardiologists for diagnosis. In the next step those electrocardiographic images were faxed to the hospital through a simple cheap fax machine, one month later the same cardiologist was asked to put his diagnosis on the copied versions of electrocardiographs, and the results were compared. Results: In 59 studied cases, the two method of diagnoses were exactly the same and only in one case the diagnoses were different. Therefore, Kappa agreement coefficient was calculated as 96%.Conclusion: According to the results of this study, general practitioners working in deprived areas can be certainly recommended to send patients’ electrocardiographic images to the cardiologists via fax in the case of needing consultation.

IL BISOGNO DELL’ORIGINE E L’ORRORE DEL MUTISMO. ALCUNE NOTE SULLA QUESTIONE DELL’ORIGINE DEL LINGUAGGIO VERBALE UMANO MORE PHILOSOPHICO

Directory of Open Access Journals (Sweden)

Salottolo Delio

2013-12-01

Full Text Available In this essay we analyze more philosophico the impact of the research on the origin of human verbal language. Starting from suggestions deriving from the work of Agamben and Lévi-Strauss, two discontinuists, we face a double contradiction. The first relates to the inability to define the birth date of human language and of human world. This consideration makes us suspect that behind the passion for this issue there is a hidden need. The second concerns the mix of fascinans and tremendum linked to human mutism, which suggests, from the dominator point of view, an attitude to human animalization, and, from the dominated point of view, a form of resistance or survival instinct. Under these lenses we will read the enfant sauvage by Itard and the Foe by Coetzee. Finally we will discuss the issue of the need for origin as modern mankind melancholia and as unresolved tension towards the future.

Orientalismi all’origine dell’architettura veneziana

Directory of Open Access Journals (Sweden)

Fontana, Vincenzo

2012-07-01

Full Text Available Between 1964 and 1968 Carlo Scarpa designs the small, precious «patio» of the Fondazione Que- rini Stampalia, in which both Mondrian and Mies van de Rohe, and ancient China and Japan, as well as Venice and the Alhambra, are finally re-read through modern eyes. An orientalist reading of the origins of Venetian architecture is exposed by Leopoldo Cicognara in «Le fabbriche più cospicue di Venezia» (1815-1820 in a posi- tive and appreciative way. The works of Pietro Selvatico similarly show his adherence to both the romantic and the positivist movements: he had been a student of Giuseppe Iappelli, who in the Moorish greenhouse of the gardens of Villa Torlonia in Rome in 1840 translated into architectural form some engravings of Murphy’s Alhambra. The apse of the Murano cathedral in his «Sulla architettura e sulla scultura in Venezia dal Medioevo» (1847 becomes extremely important for John Ruskin. Indeed, through a much deeper analysis of this work, it is seen to become for Ruskin the key of Venetian ornament law until the early Renaissance architecture. Ruskin lays down this law of ornament scientifically and poetically: it is made not only of geometric lines and colors, but of matter and patinas. Thus, Venice offers a pattern to contemporary Victorian architecture and to the future «organic architecture». Camillo Boito traces the Christian character of Murano’s architecture back to its Byzantine and Lombard origins, and compares it with Syrian, Armenian and Coptic churches illustrated by Melchior de Vogüe in «Syrie Central» (1865-1872. These in turn influence the mausoleum erected by Ponti in the center of the cemetery in Gallarate (1865-1869. «Degli stili nell’architettura», ii, 1897, and the «Atlas» of Luigi Archinti (Chirtani borrow from the works of the French diplomat detailed surveys of churches and mon- asteries of Syria indicated by Boito as models for future architects.

Full Text Available Background: It is desirable to have skilled midwives to provide competent care in hospital and community setting. Aims and Objectives: The objectives were to assess curriculum adequacy, preparedness and job preferences of prospective nurses. Materials and Methods: A descriptive survey was used for the study. Thestudy was carried out at nursing institutes in Ahmednagar District, Maharashtra, India. The participants were the 200 prospective Nurses(final year Nursing students of General Nursing and B.Sc Nursing Programme, who had undergone midwifery examination. A semi structured questionnaire with self report technique method was used. Results: 20.57% and 89.1% students respectively felt that, thetheory input and allotted clinical hours were adequate. During the clinical posting, 29.7% felt that they did not get the opportunity to work in midwifery sections. 33.1% students expressed that they did not get cases as per the requirement prescribed by Indian NursingCouncil.13.7% and 33.7% students respectively agreed that they lacked confidence to perform abdominal palpation of antenatal cases & conduct deliveries independently. A few (26.2% expressed their inability to resuscitate the newborn. 89.1% said that they needed more experience to work independently as midwives. Everyone felt the need of in-service education and majority (77.2% felt that its duration should be either three months or more. Conclusion: Present study reveals that only 7% of the prospective nurses are ready to work in midwifery section. Only 13.7% of the prospective nurses are ready to work in rural area. Since there is a shortfall of 70.02% forspeciality of obstetrics and gynecology in rural health (GOI, 1997, and there are only 40 qualified nurse midwives per 100,000 births inIndia or only one midwife for 2500 births in rural areas, it is imperative to strengthen midwifery training to bridge this gap.

Hunger and love: Schiller and the origin of drive dualism in Freud's work.

Science.gov (United States)

Cotti, Patricia

2007-02-01

"The interpretation of dreams" was the first text in which Freud referred to the system of two drives (drive of self-preservation and the sexual drive). In order to understand how this question was at work in Freud's mind, one has to go back to 1898, when Freud began to write the third chapter of "The interpretation of dreams". One can then see, in contrast with Sulloway's assertions, how Freud was inspired by Schiller, whose shadow haunted his dreams between April and December 1898. The analysis of these dreams emphasizes how the references to Schiller's works and to the drive of self-preservation cover sexual impulses, in particular, those connected with the relationship to the father. The food drive or drive of self-preservation also enabled Freud to construct a heroic romance. He was thereby able to bury an internal criticism which was at odds with his persistence in describing the father as a seducer, and to conceal scenes in which he was defeated and sexually subdued by another boy.

Origin of Evolution versus Origin of Life: A Shift of Paradigm

Directory of Open Access Journals (Sweden)

Marc Tessera

2011-06-01

Full Text Available The question of the primordial ancestor must be approached through the search for the origin of evolution, not through the search for the origin of life. There is a major issue with the concept of life because it is impossible to define, thus is not a scientific but a metaphysical concept. On the contrary, evolution may be defined by as few as three conditions. These do not necessarily involve biopolymers. However, such an approach must give clues to explain the emergence of distinct lineages to allow Darwinian natural selection. A plausible solution exists within an autotrophic lipidic vesicle-based model that is presented. The model requires the existence of hydrothermal sites such as the Lost City Hydrothermal Field leading to specific constraints. For this reason Mars and Europa may be questioned as possible cradles of evolution. If we replace the search for the origin of life by the one for the origin of evolution our priority first is to find a consensus on the minimal conditions that would allow evolution to emerge and persist anywhere in the universe.

[Human origin and evolution. A review of advances in paleoanthropology, comparative genetics, and evolutionary psychology].

Markov, A V

2009-01-01

In his main work, "On the origin of species", Darwin has refrained from discusion of the origin of man; be only mentioned that his theory would "throw light" on this problem. This famous Darwin's phrase turned out to be one of the most succesful scientific predictions. In the present paper some of the most important recent adavnces in paleoanthroplogy, comparative genetics and evolutionary psychology are reviewed. These three disciplines currently contribute most to our knowledge of anthropogenesis. The review demonstrates that Darwin's ideas not only "threw light" on human origin and evolution; they provided a comprehensive framework for a great variety of studies concerning different aspects of anthropogenesis.

Organic Minerals in the Origin of Life

Benner, S.; Biondi, E.; Kim, H. J.

2017-12-01

Models for the origin of life are plagued by fundamental problems that, due to their difficulty, are called "paradoxes". One of these, known to anyone who has ever worked in a kitchen, is that organics, when given energy and left to itself, does not generate life. Rather, organics devolve to give tarry mixtures that become increasingly complex and increasingly less likely to support life (like asphalt). However, even if those mixtures escape devolution to create something useful for Darwinism, like building blocks for RNA, the water in which they must work is corrosive, leading to their destruction. Even if RNA is created, it is itself easily degraded. One current trend to manage those paradoxes turns to minerals in environments on early Earth. Inorganic minerals containing borate have now been shown to prevent the destruction of ribose (the R in RNA) and other carbohydrates essential for early Earth. Evaporite desert basins supplied with aqueous runoff from tourmaline-containing basalts are ideal environments for forming borate minerals, especially if they are made alkaline by serpentinizing peridotite. In the evaporite environments, drying cycles mitigate the destructive capability of water. Further, we have shown that phosphate is segregated from calcium (avoiding formation of relatively unreacted apatites) if magnesium and borate are present. Further, a common magnesium borophosphate (luneburgite) not only makes phosphate available for prebiotic synthesis, but selectively phosphorylates RNA building blocks as it releases borate to stabilize them against further degradation. Finally, a variety of minerals bind and stabilize RNA itself. Research in this area has also discovered organic minerals that might have been relevant to the origins of life on Earth. Such minerals are scarce on Earth today, since they are easily consumed by microbial communities. However, on a prebiotic Earth, organic minerals could have stored organic species as intermediates towards our

Teaching Creative Thinking Skills with Laboratory Work

Nur Khoiri

2017-12-01

Full Text Available Research on figuring out the ways to teach creative thinking skills via learning processes has been carried out. One of the methods applied to be efficient to teach creative thinking skills is laboratory work. Laboratory work is an important process in learning physics since students tend to find it hard to understand physical concepts if they are only taught verbally. Students will understand better when they are given real life examples and are allowed to learn the concepts through the laboratory work, whenever possible. The research was conducted at SMAN 1 Bringin by employing the quasi-experiment pre-test - post-test control group design. Creative thinking skills were measured based on four indicators: flexibility, fluency, originality, and detail. Results show that laboratory work was suitable to improve students’ fluent thinking ability with 77% students showing improvement, and it was also a fit to improve students’ original thinking with 84% students showing improvement. The experiment class revealed a gain of 0.51, taken from an average pre-test score of 45.64 compared to the average post-test score of 73.5, which is an increase of 27.86. Meanwhile, the control class resulted in a gain of 0.40, taken from an average pre-test score of 39.11 compared to the average post-test score of 83.44, which is an increase of 24.33.

Associations between psychosocial work environment and excess weight have not been systematically addressed. The aim of this systematic review was to summarize the published evidence for the associations of psychosocial factors at work and long work hours with weight-related outcomes . Methods We conducted a search of Medline and Embase for all original articles published up to September 2012 using predefined keywords. After excluding studies with a definite selection bias, we included 39 articles. About 60% of the studies reported at least one positive association between psychosocial factors at work and a weight-related outcome. However, 76% of the tested associations were found to be non-significant. Furthermore, the associations were rather weak. Studies of higher quality tended to observe associations more often than those of lower quality. Positive associations were found more frequently (i) among women versus men, (ii) in cross-sectional versus longitudinal studies, and (iii) for overweight or obesity versus other outcomes. About 70% of the studies reported positive associations between long work hours and weight-related outcomes. All four studies that evaluated the association between working overtime and weight gain (three longitudinal and one cross-sectional), showed a positive association among men and two of them also observed associations among women. We found evidence for weak associations between psychosocial factors at work and excess weight. Associations were observed between long work hours, working overtime, and weight gain, especially among men. More cohort studies among non-obese baseline participants using appropriate analytical methods based on an elaborated hypothetical model are needed.

Computational logic: its origins and applications.

Science.gov (United States)

Paulson, Lawrence C

2018-02-01

Computational logic is the use of computers to establish facts in a logical formalism. Originating in nineteenth century attempts to understand the nature of mathematical reasoning, the subject now comprises a wide variety of formalisms, techniques and technologies. One strand of work follows the 'logic for computable functions (LCF) approach' pioneered by Robin Milner, where proofs can be constructed interactively or with the help of users' code (which does not compromise correctness). A refinement of LCF, called Isabelle, retains these advantages while providing flexibility in the choice of logical formalism and much stronger automation. The main application of these techniques has been to prove the correctness of hardware and software systems, but increasingly researchers have been applying them to mathematics itself.

Attributional biases about the origins of attitudes: externality, emotionality, and rationality.

Science.gov (United States)

Kenworthy, Jared B; Miller, Norman

2002-05-01

Pilot work and 3 studies investigated the ways people explain the origins of attitudes. Study I examined the use of 3 dimensions (externality, rationality, emotionality) to explain the origin of people's own, in-group, and out-group attitudes. Attributions for own attitudes were the least externally and emotionally based and the most rationally based. By comparison with the out-group, less externality, less emotionality, and more rationality also were attributed to in-group attitudes. Studies 2 and 3 examined the effects of intergroup threat on attributions for in- and out-group attitude positions. Under high threat, more externality and emotionality but less rationality were attributed to out-group attitudes than under low threat. Intergroup differentiation mediated the difference between out-group attributions under high and low threat.

Nowadays, works of art can be enjoyed in both their original and reproduced format. The aim of this study was to investigate whether the format of a work of art could influence physiological and cognitive responses in beholders. Two abstract works of art and their digital reproductions were selected as experimental stimuli and displayed for 2min to 60 participants in a museum. HRV, HR, and RMSSD were recorded, while participants observed the works of art. Subsequently, participants provided behavioral ratings of color intensity, emotional intensity, aesthetic evaluation, perceived movement, and desire to touch the works of art. Results demonstrated that the faithful high-quality digital reproduction of works of art could be as arousing as the original works of art, but at the same time, they cannot replace the experience of standing in front of an authentic work of art in terms of explicit hedonic attributed values. Furthermore, specific interactions between individual inclinations to identify with fictional characters and acquired art competences in the context of aesthetic experience were found. © 2018 Elsevier B.V.

Eastern and western happiness in work behavior

Directory of Open Access Journals (Sweden)

Jaroslava Kubátová

2017-10-01

Full Text Available The purpose of this article is to clarify what motivates East Asian work behavior. The research question is: How can a Western manager better understand work behavior and motivation in East Asian cultures? Knowledge about national culture, motivation and the concept of happiness are connected via deductive and comparative methods, while pointing out their new connections and relations. We argue that work motivation in East Asian cultures can be explained using the self-concept-based motivation meta-theory as it corresponds to the East Asian concept of face and that the East Asian self-concept originates with the Eastern concept of happiness.

Since 1989, many experimenters worked on low-energy nuclear reactions (LENR). They face both an experimental and a theoretical dilemma: how to design simple and convincing experiments in a complex system and if the phenomenon has a nuclear origin, why do they observe no radiation. A rather simple water mass flow calorimeter was designed to study this phenomenon under different experimental conditions. First results indicate that a high-density current induced an exothermic reaction in a hydrogen processed palladium wire. A working hypothesis is presented to solve the theoretical dilemma. This working hypothesis is based on the possible existence of a still hypothetical proton/electron resonance. We underline that a working hypothesis is not a theory presented to explain the phenomenon; this is just a conceptual scheme to drive the authors to build experiments. (author)

[Job demands and work-family conflict in a health care staff. The role of work shifts].

Science.gov (United States)

Zito, Margherita; Colombo, Lara; Mura, Gabriella

2013-01-01

Work-family conflict (wfc), that originates from an incompatibility between the job and the family demands, is a very relevant topic in health care context, as suggested by NEXT study. Work overload and schedule organization are dimensions that can affect wfc, and particularly, studies indicate work shifts as one of its main determinants, as they limit the work-family balance and represent one of the prime risk factors for workers' health. The aim of this study was to detect the role of some job demands (both general and specific) and of schedule organization in determining the wfc experience, with particular attention to work shifts. Respondents to our questionnaire are 207 nurses of a north Italian public health organization. They are mostly women (92.8%) and their average age is 42. Data analysis shows that wfc is mostly influenced by work shifts, but also by work overload, cognitive load and by on-call availability. Staff working on shifts and on-call availability perceive a higher wfc than their colleagues without work shifts and on-call availability. The central role of work shifts in determining wfc suggests the need to act on schedule organization and on training programs for supervisors and workers.

Neural networks applied to discriminate botanical origin of honeys.

Science.gov (United States)

Anjos, Ofélia; Iglesias, Carla; Peres, Fátima; Martínez, Javier; García, Ángela; Taboada, Javier

2015-05-15

The aim of this work is develop a tool based on neural networks to predict the botanical origin of honeys using physical and chemical parameters. The managed database consists of 49 honey samples of 2 different classes: monofloral (almond, holm oak, sweet chestnut, eucalyptus, orange, rosemary, lavender, strawberry trees, thyme, heather, sunflower) and multifloral. The moisture content, electrical conductivity, water activity, ashes content, pH, free acidity, colorimetric coordinates in CIELAB space (L(∗), a(∗), b(∗)) and total phenols content of the honey samples were evaluated. Those properties were considered as input variables of the predictive model. The neural network is optimised through several tests with different numbers of neurons in the hidden layer and also with different input variables. The reduced error rates (5%) allow us to conclude that the botanical origin of honey can be reliably and quickly known from the colorimetric information and the electrical conductivity of honey.

Origin Licensing Requires ATP Binding and Hydrolysis by the MCM Replicative Helicase

Coster, Gideon; Frigola, Jordi; Beuron, Fabienne; Morris, Edward P.; Diffley, John F.X.

2014-01-01

Summary Loading of the six related Minichromosome Maintenance (MCM) proteins as head-to-head double hexamers during DNA replication origin licensing is crucial for ensuring once-per-cell-cycle DNA replication in eukaryotic cells. Assembly of these prereplicative complexes (pre-RCs) requires the Origin Recognition Complex (ORC), Cdc6, and Cdt1. ORC, Cdc6, and MCM are members of the AAA+ family of ATPases, and pre-RC assembly requires ATP hydrolysis. Here we show that ORC and Cdc6 mutants defective in ATP hydrolysis are competent for origin licensing. However, ATP hydrolysis by Cdc6 is required to release nonproductive licensing intermediates. We show that ATP binding stabilizes the wild-type MCM hexamer. Moreover, by analyzing MCM containing mutant subunits, we show that ATP binding and hydrolysis by MCM are required for Cdt1 release and double hexamer formation. This work alters our view of how ATP is used by licensing factors to assemble pre-RCs. PMID:25087873

2013-01-01

The aim of this work was to find palynological markers which permit differentiate honeys from the departments of Boyaca, Cundinamarca, Santander and Magdalena, by its geographical and botanical origin. Melissopalynological analyses were made of 184 honey samples obtained from 131 localities. A discriminant analysis and comparisons between the species composition of honey samples were made to find geo-graphical and botanical origin differences. A total of 297 pollen species distributed in 69 families was found, being Mimosa sp., Cecropia sp., Eucalyptus sp., Piper sp. and Quercus humboldtii the most representatives. The major families were Fabaceae, Asteraceae, Myrtaceae, Rubiaceae, Fagaceae and Melastomataceae. Six honey groups differentiated by its geographical origin were found: Altiplano Cundiboyacense, Medio Chicamocha, Sumapaz, Bajo Chicamocha, Sierra Nevada de Santa Marta and Comunera Province. In a broader scale, honeys from the Andean and sub-Andean regions could be differentiated as well. Between the honey types differentiated by its botanical origin, the most important were monofloral honeys of Trifolium pratense, Coffea arabica, Eucalyptus sp., Inga sp. and Heliocarpus americanus, Asteraceae oligofloral honeys and mixtures of Q. humboldtii honeydew and floral nectar (Eucalyptussp., Brassicaceae Type, Asteraceae). This information in addition to the obtained by physico-chemical and sensorial analysis, may be the basis to acquire honeys' origin denomination.

The embryonic origin of the ampullate silk glands of the spider Cupiennius salei.

Science.gov (United States)

Hilbrant, Maarten; Damen, Wim G M

2015-05-01

Silk production in spiders is considered a key innovation, and to have been vital for the diversification of the clade. The evolutionary origin of the organs involved in spider silk production, however, and in particular of the silk glands, is poorly understood. Homologies have been proposed between these and other glands found in arachnids, but lacking knowledge of the embryonic development of spider silk glands hampers an evaluation of hypotheses. This study focuses on the embryonic origin of the largest silk glands of the spider Cupiennius salei, the major and minor ampullate glands. We show how the ampullate glands originate from ectodermal invaginations on the embryonic spinneret limb buds, in relation to morphogenesis of these buds. Moreover, we visualize the subsequent growth of the ampullate glands in sections of the early postembryonic stages. The invaginations are shown to correlate with expression of the proneural gene CsASH2, which is remarkable since it has been proposed that spider silk glands and their nozzles originate from sensory bristles. Hence, by confirming the ectodermal origin of spider silk glands, and by describing the (post-)embryonic morphogenesis of the ampullate glands, this work provides a starting point for further investigating into the genetic program that underlies their development.

Hopkins, Burt C

2011-01-01

Burt C. Hopkins presents the first in-depth study of the work of Edmund Husserl and Jacob Klein on the philosophical foundations of the logic of modern symbolic mathematics. Accounts of the philosophical origins of formalized concepts-especially mathematical concepts and the process of mathematical abstraction that generates them-have been paramount to the development of phenomenology. Both Husserl and Klein independently concluded that it is impossible to separate the historical origin of the thought that generates the basic concepts of mathematics from their philosophical meanings. Hopkins explores how Husserl and Klein arrived at their conclusion and its philosophical implications for the modern project of formalizing all knowledge.

The origin of the residual conductivity of GaN films on ferroelectric materials

Science.gov (United States)

Lee, Kyoung-Keun; Cai, Zhuhua; Ziemer, Katherine; Doolittle, William Alan

2009-08-01

In this paper, the origin of the conductivity of GaN films grown on ferroelectric materials was investigated using XPS, AES, and XRD analysis tools. Depth profiles confirmed the existence of impurities in the GaN film originating from the substrates. Bonding energy analysis from XPS and AES verified that oxygen impurities from the substrates were the dominant origin of the conductivity of the GaN film. Furthermore, Ga-rich GaN films have a greater chance of enhancing diffusion of lithium oxide from the substrates, resulting in more substrate phase separation and a wider inter-mixed region confirmed by XRD. Therefore, the direct GaN film growth on ferroelectric materials causes impurity diffusion from the substrates, resulting in highly conductive GaN films. Future work needs to develop non-conductive buffer layers for impurity suppression in order to obtain highly resistive GaN films.

Dynamic origins of fermionic D -terms

Science.gov (United States)

Hudson, Jonathan; Schweitzer, Peter

2018-03-01

The D -term is defined through matrix elements of the energy-momentum tensor, similarly to mass and spin, yet this important particle property is experimentally not known any fermion. In this work we show that the D -term of a spin 1/2 fermion is of dynamical origin: it vanishes for a free fermion. This is in pronounced contrast to the bosonic case where already a free spin-0 boson has a non-zero intrinsic D -term. We illustrate in two simple models how interactions generate the D -term of a fermion with an internal structure, the nucleon. All known matter is composed of elementary fermions. This indicates the importance to study this interesting particle property in more detail, which will provide novel insights especially on the structure of the nucleon.

Unraveling the origin of the Appalachian gametophyte, Vittaria appalachiana.

Science.gov (United States)

Pinson, Jerald B; Schuettpelz, Eric

2016-04-01

Ferns and lycophytes are distinct among plants in producing two free-living life stages: a long-lived sporophyte phase and a (usually) short-lived gametophyte phase. Notably, however, some species have perennial, vegetatively reproducing gametophytes. Vittaria appalachiana is one of just three species in which mature sporophytes are unknown. It has a wide range throughout the Appalachian Mountains and Plateau, where it reproduces asexually via gemmae. The origin of V. appalachiana, however, has long been a mystery, with most previous studies suggesting it may have resulted from hybridization of two closely related Vittaria species (V. graminifolia and V. lineata). A four-gene plastid data set including 32 samples of six Vittaria species, plus samples of five outgroup species, was analyzed to uncover phylogenetic relationships. Additional analyses of nuclear DET1 gene sequences allowed for the examination of hypotheses involving a hybrid origin for V. appalachiana. In the plastid phylogeny, V. appalachiana is well supported as monophyletic, but is embedded within V. graminifolia. With the exception of a single aberrant allele, this result is mirrored in the nuclear tree. Through analyses of plastid and nuclear data sets, this study demonstrates that a hybrid origin for V. appalachiana is unlikely. Instead, it appears that this species emerged from within the V. graminifolia lineage. Further work is needed to fully elucidate the genetic structure within this group. © 2016 Botanical Society of America.

Mapping replication origins in yeast chromosomes.

Science.gov (United States)

Brewer, B J; Fangman, W L

1991-07-01

The replicon hypothesis, first proposed in 1963 by Jacob and Brenner, states that DNA replication is controlled at sites called origins. Replication origins have been well studied in prokaryotes. However, the study of eukaryotic chromosomal origins has lagged behind, because until recently there has been no method for reliably determining the identity and location of origins from eukaryotic chromosomes. Here, we review a technique we developed with the yeast Saccharomyces cerevisiae that allows both the mapping of replication origins and an assessment of their activity. Two-dimensional agarose gel electrophoresis and Southern hybridization with total genomic DNA are used to determine whether a particular restriction fragment acquires the branched structure diagnostic of replication initiation. The technique has been used to localize origins in yeast chromosomes and assess their initiation efficiency. In some cases, origin activation is dependent upon the surrounding context. The technique is also being applied to a variety of eukaryotic organisms.

On 'lost' indigenous etymological origins with the specific case of the name Ameiva.

Science.gov (United States)

Angeli, Nicole Frances

2018-01-01

Modern biology builds upon the historic exploration of the natural world. Recognizing the origin of a species' name is one path to honor the historic exploration and description of the natural world and the indigenous peoples that lived closely with organisms prior to their description. While digitization of historic papers catalogued in databases such as the Biodiversity Heritage Library (BHL) allows for searching of the first use and origin of names, the rapid pace of taxonomic publishing can occlude a thorough search for etymologies. The etymological origin of the genus name Ameiva is one such case; while unattributed in multiple recent works, it is of Tupí language origin. The first description was in the Historiae Rerum Naturalium Brasiliae by George Marcgrave (1648). Ameiva was the name used by Marcgrave's Amerindian hosts in 17 th century Dutch Brazil, where local people spoke the now extinct language Tupí. The Tupí origin was not lost, however, until as recently as the 2000s. Herein, the pre- and post-Linnaean use of the name Ameiva is traced and when the name is attributed to the Tupí language and to Marcgrave through time it is noted. The opportunity to discover and/or recover etymological origins, especially names from extinct and indigenous languages, provides insight into the early Western sciences. Careful study of etymology by naturalists is consistent with the idea that science is an evolving process with many predecessors to appreciate.

Professional burnout and work engagement among dentists.

Te Brake, Hans; Bouman, Anne-Marthe; Gorter, Ronald; Hoogstraten, Johan; Eijkman, Michiel

2007-06-01

A recent development within burnout research is the shift to its conceptual opposite: work engagement. This study aimed to unravel the concepts of burnout and work engagement, and to determine their levels among dentists. A representative sample of 497 Dutch general dental practitioners was included (survey response rate of 59%), consisting of 372 men and 121 women (the gender of 4 dentists remained unknown). The hypothesized three-factor structure of work engagement (vigor, dedication, and absorption), as measured by the Utrecht Work Engagement Scale (UWES), was substantiated among dentists. It was also found that work engagement was related negatively to burnout, as measured by the Maslach Burnout Inventory (MBI). However, a model consisting of a reduced ('core') burnout factor and an 'enhanced' engagement factor (composed of the three original factors plus the burnout factor, personal accomplishment) showed the best fit. Overall burnout levels among dentists are low, and the levels of engagement indicate that dentists have a positive working attitude.

Cognitive debiasing 1: origins of bias and theory of debiasing.

Science.gov (United States)

Croskerry, Pat; Singhal, Geeta; Mamede, Sílvia

2013-10-01

Numerous studies have shown that diagnostic failure depends upon a variety of factors. Psychological factors are fundamental in influencing the cognitive performance of the decision maker. In this first of two papers, we discuss the basics of reasoning and the Dual Process Theory (DPT) of decision making. The general properties of the DPT model, as it applies to diagnostic reasoning, are reviewed. A variety of cognitive and affective biases are known to compromise the decision-making process. They mostly appear to originate in the fast intuitive processes of Type 1 that dominate (or drive) decision making. Type 1 processes work well most of the time but they may open the door for biases. Removing or at least mitigating these biases would appear to be an important goal. We will also review the origins of biases. The consensus is that there are two major sources: innate, hard-wired biases that developed in our evolutionary past, and acquired biases established in the course of development and within our working environments. Both are associated with abbreviated decision making in the form of heuristics. Other work suggests that ambient and contextual factors may create high risk situations that dispose decision makers to particular biases. Fatigue, sleep deprivation and cognitive overload appear to be important determinants. The theoretical basis of several approaches towards debiasing is then discussed. All share a common feature that involves a deliberate decoupling from Type 1 intuitive processing and moving to Type 2 analytical processing so that eventually unexamined intuitive judgments can be submitted to verification. This decoupling step appears to be the critical feature of cognitive and affective debiasing.

High pressure membrane foulants of seawater, brackish water and river water: Origin assessed by sugar and bacteriohopanepolyol signatures

KAUST Repository

Mondamert, Leslie

2011-01-01

The present work aimed to study the origin of foulant material recovered on membranes used in water treatment. Firstly, sugar signatures were assessed from the monosaccharide composition. As results were not conclusive, a statistical approach using discriminant analysis was applied to the sugar data set in order to predict the origin of the foulant material. Three groups of various origins (algal, microbial, continental dissolved organic matter) were used as sugar references for the prediction. The results of the computation showed that the origin of reverse osmosis (RO) seawater foulant material is influenced by both the location of the water sources and the season. RO brackish water and nanofiltration river water foulant materials had a terrestrial origin. Secondly, bacteriohopanepolyol signatures indicated that RO seawater foulant material had a marine signature, RO brackish water foulant material had both a marine and a terrestrial origin and the nanofiltration river water foulant material contained only a terrestrial signature. © 2011 Taylor & Francis.

Fast image reconstruction for Compton camera using stochastic origin ensemble approach.

Science.gov (United States)

Andreyev, Andriy; Sitek, Arkadiusz; Celler, Anna

2011-01-01

Compton camera has been proposed as a potential imaging tool in astronomy, industry, homeland security, and medical diagnostics. Due to the inherent geometrical complexity of Compton camera data, image reconstruction of distributed sources can be ineffective and/or time-consuming when using standard techniques such as filtered backprojection or maximum likelihood-expectation maximization (ML-EM). In this article, the authors demonstrate a fast reconstruction of Compton camera data using a novel stochastic origin ensembles (SOE) approach based on Markov chains. During image reconstruction, the origins of the measured events are randomly assigned to locations on conical surfaces, which are the Compton camera analogs of lines-of-responses in PET. Therefore, the image is defined as an ensemble of origin locations of all possible event origins. During the course of reconstruction, the origins of events are stochastically moved and the acceptance of the new event origin is determined by the predefined acceptance probability, which is proportional to the change in event density. For example, if the event density at the new location is higher than in the previous location, the new position is always accepted. After several iterations, the reconstructed distribution of origins converges to a quasistationary state which can be voxelized and displayed. Comparison with the list-mode ML-EM reveals that the postfiltered SOE algorithm has similar performance in terms of image quality while clearly outperforming ML-EM in relation to reconstruction time. In this study, the authors have implemented and tested a new image reconstruction algorithm for the Compton camera based on the stochastic origin ensembles with Markov chains. The algorithm uses list-mode data, is parallelizable, and can be used for any Compton camera geometry. SOE algorithm clearly outperforms list-mode ML-EM for simple Compton camera geometry in terms of reconstruction time. The difference in computational time

Although Malta is historically linked with the zoonosis brucellosis, there had not been a case of the disease in either the human or livestock population for several years. However, in July 2013 a case of human brucellosis was identified on the island. To determine whether this recent case originated in Malta, four isolates from this case were subjected to molecular analysis. Molecular profiles generated using multilocus sequence analysis and multilocus variable number tandem repeat for the recent human case isolates and 11 Brucella melitensis strains of known Maltese origin were compared with others held on in-house and global databases. While the 11 isolates of Maltese origin formed a distinct cluster, the recent human isolation was not associated with these strains but instead clustered with isolates originating from the Horn of Africa. These data was congruent with epidemiological trace-back showed that the individual had travelled to Malta from Eritrea. This work highlights the potential of using molecular typing data to aid in epidemiological trace-back of Brucella isolations and assist in monitoring of the effectiveness of brucellosis control schemes.

Origin of clear cell carcinoma: nature or nurture?

Science.gov (United States)

Kolin, David L; Dinulescu, Daniela M; Crum, Christopher P

2018-02-01

A rare but serious complication of endometriosis is the development of carcinoma, and clear cell and endometrioid carcinomas of the ovary are the two most common malignancies which arise from endometriosis. They are distinct diseases, characterized by unique morphologies, immunohistochemical profiles, and responses to treatment. However, both arise in endometriosis and can share common mutations. The overlapping mutational profiles of clear cell and endometrioid carcinomas suggest that their varied histologies may be due to a different cell of origin which gives rise to each type of cancer. Cochrane and colleagues address this question in a recent article in this journal. They show that a marker of ovarian clear cell carcinoma, cystathionine gamma lyase, is expressed in ciliated cells. Similarly, they show that markers of secretory cells (estrogen receptor and methylenetetrahydrofolate dehydrogenase 1) are expressed in ovarian endometrioid carcinoma. Taken together, they suggest that endometrioid and clear cell carcinomas arise from cells related to secretory and ciliated cells, respectively. We discuss Cochrane et al's work in the context of other efforts to determine the cell of origin of gynecological malignancies, with an emphasis on recent developments and challenges unique to the area. These limitations complicate our interpretation of tumor differentiation; does it reflect nature imposed by a specific cell of origin or nurture, by either mutation(s) or environment?

We provide direct evidence to understand the origin of low thermal conductivity of SnSe using elastic measurements. Compared to state-of-the-art lead chalcogenides Pb Q (Q =Te , Se, S), SnSe exhibits low values of sound velocity (˜1420 m /s ) , Young's modulus (E ˜27.7 GPa ) , and shear modulus (G ˜9.6 GPa ) , which are ascribed to the extremely weak Sn-Se atomic interactions (or bonds between layers); meanwhile, the deduced average Grüneisen parameter γ of SnSe is as large as ˜3.13, originating from the strong anharmonicity of the bonding arrangement. The calculated phonon mean free path (l ˜ 0.84 nm) at 300 K is comparable to the lattice parameters of SnSe, indicating little room is left for further reduction of the thermal conductivity through introducing nanoscale microstructures and microscale grain boundaries. The low elastic properties indicate that the weak chemical bonding stiffness of SnSe generally causes phonon modes softening which eventually slows down phonon propagation. This work provides insightful data to understand the low lattice thermal conductivity of SnSe.

Characterizing the original ejection velocity field of the Koronis family

Science.gov (United States)

Carruba, V.; Nesvorný, D.; Aljbaae, S.

2016-06-01

An asteroid family forms as a result of a collision between an impactor and a parent body. The fragments with ejection speeds higher than the escape velocity from the parent body can escape its gravitational pull. The cloud of escaping debris can be identified by the proximity of orbits in proper element, or frequency, domains. Obtaining estimates of the original ejection speed can provide valuable constraints on the physical processes occurring during collision, and used to calibrate impact simulations. Unfortunately, proper elements of asteroids families are modified by gravitational and non-gravitational effects, such as resonant dynamics, encounters with massive bodies, and the Yarkovsky effect, such that information on the original ejection speeds is often lost, especially for older, more evolved families. It has been recently suggested that the distribution in proper inclination of the Koronis family may have not been significantly perturbed by local dynamics, and that information on the component of the ejection velocity that is perpendicular to the orbital plane (vW), may still be available, at least in part. In this work we estimate the magnitude of the original ejection velocity speeds of Koronis members using the observed distribution in proper eccentricity and inclination, and accounting for the spread caused by dynamical effects. Our results show that (i) the spread in the original ejection speeds is, to within a 15% error, inversely proportional to the fragment size, and (ii) the minimum ejection velocity is of the order of 50 m/s, with larger values possible depending on the orbital configuration at the break-up.

Necrotizing cellulitis of dental origin is a serious disease and requires prompt and effective management to avoid adverse outcomes. The purpose of this work is to describe the diagnostic and therapeutic difficulties encountered in this condition. This was a prospective study in the thoracic surgery department of Mali Hospital from January 2011 to February 2015. We collected consecutively 19 cases of complicating cervico-facial cellulitis of dental origin. The anatomical and clinical aspects, therapeutic modalities and difficulties are described. Dental pain and fever were the predominant symptoms followed by cervical edema. Chest CT-scan was the basis for the diagnosis in all cases. Cervicotomy with debridement was the most performed surgical procedure. Pleural drainage was performed in 6 cases. Three patients (15.8%) died. Necrotizing cellulitis of dental origin is a serious disease with high morbidity and mortality. The key radiological examination is the thoracic CT-scan. Early medico-surgical management by emergency care, tailored antibiotic therapy, removal of necrotizing tissues and drainage of collections are required to deliver a good outcome.

Origin and evolution of Sariñena Lake (central Ebro Basin): A piping-based model

Science.gov (United States)

Castañeda, Carmen; Javier Gracia, F.; Rodríguez-Ochoa, Rafael; Zarroca, Mario; Roqué, Carles; Linares, Rogelio; Desir, Gloria

2017-08-01

The origin and nature of the numerous lakes in the central Ebro Basin have been interpreted according to the prevailing arid or semiarid conditions, the easily-eroded materials and the solubility of the gypsum- and/or carbonate-rich Tertiary/Cenozoic substratum, involving important dissolution (karstic) and/or aeolian deflation. However, the origin of Sariñena Lake, the largest in the central Ebro Basin, remains unknown since the typical lake-generating processes in the region are not applicable. This work provides significant clues to the genesis and evolution of Sariñena Lake in a regional context. The combination of geomorphological mapping and high resolution LiDAR data together with sedimentological observations, the characterisation of soils and sediments around the lake, and the application of high-resolution geophysical techniques suggest that piping is the major genetic process driving the evolution of the Sariñena depression and lake. Field evidence demonstrates that piping is, at present, the most important erosive process in the region, generating significant collapse and surface lowering. Sariñena Lake is located within a deep endorheic depression excavated from Na-rich Tertiary materials. This work hypothesises that once an early, fluvially-originated palustrine area had developed, the progressive lowering of the regional water table linked to regional fluvial incision favoured the establishment of a hydrological gradient high enough to trigger piping processes within the claystones and siltstones underlying the original palustrine area. The Quaternary evolution of the Sariñena lacustrine basin was then controlled by successive water table fluctuations, linked to different phases of incision and alluvial deposition in the surrounding fluvial systems. All the evidence supporting a piping-related origin for this lake, together with examples of lakes generated by similar processes in different contexts, is used to propose a new genetic type of

Biosynthetic origin of acetic acid using SNIF-NMR

The main purpose of this work is to describe the use of the technique Site-Specific Natural Isotopic Fractionation of hydrogen (SNIF-NMR), using 2 H and 1 H NMR spectroscopy, to investigate the biosynthetic origin of acetic acid in commercial samples of Brazilian vinegar. This method is based on the deuterium to hydrogen ratio at a specific position (methyl group) of acetic acid obtained by fermentation, through different biosynthetic mechanisms, which result in different isotopic ratios. We measured the isotopic ratio of vinegars obtained through C 3 , C 4 , and CAM biosynthetic mechanisms, blends of C 3 and C 4 (agrins) and synthetic acetic acid. (author)

Origin of transverse momentum in relativistic heavy-ion collisions: Microscopic study

International Nuclear Information System (INIS)

Blaettel, B.; Koch, V.; Lang, A.; Weber, K.; Cassing, W.; Mosel, U.

1991-01-01

We study the origin of the transverse momentum distribution in heavy-ion collisions within a relativistic transport approach. To achieve a better understanding of the reaction dynamics, we decompose the total p t distribution into a mean-field, N-N collision, and Fermi-momentum part. We find that the origin of the transverse momentum strongly depends on the rapidity region. Our investigation of the impact-parameter and mass dependence suggests that peripheral collisions may be useful to investigate the momentum dependence of the mean-field in the nucleus-nucleus case, whereas the mass dependence could give hints about the N-N-collision part. Only after these two issues are settled it may be possible to extract information about the density dependence in central collisions, which may, however, necessitate reactions at even higher energies than the 800 MeV/nucleon considered in this work

2013-01-01

The aim of this study is to evaluate the reproducibility of working casts of a digital impression system by comparing them with the original, virtual, and rapid prototyping casts. A total of 54 cast sets in clinically stable occlusion were used. They were scanned by an iTero intraoral scanner and converted into STL format virtual casts. Rapid prototyping casts and polyurethane casts were fabricated from the iTero milling system based on the virtual casts. Several horizontal and vertical measurements were performed from the four types of casts, that is, original stone casts, virtual casts, rapid prototyping casts, and polyurethane casts of iTero. Measurement error, intraclass correlation coefficient (ICC), and differences among the casts were calculated and compared. Casts from iTero milling machines exhibited greater dimensional differences and lower ICC values than did other casts. In addition, many of the measurements of the iTero working casts showed statistically significant differences in comparison to the three other types of casts. In contrast, there were no statistically significant differences between the virtual and original casts. Virtual casts made by the iTero intraoral scanner exhibited excellent reproducibility. However, the casts from the iTero milling machine showed greater dimensional differences and lower reproducibility compared to other types of casts.

Electronic viewbox: An integrated image diagnostic working station

International Nuclear Information System (INIS)

Minato, K.; Komori, M.; Hirakawa, A.; Kuwahara, M.; Yonekura, Y.; Torizuka, K.; Brill, A.B.

1985-01-01

Recent development in medical imaging technology have been introducing variety of digital images in clinical medicine, and handling these multi-modality digital images in one place is needed for efficient clinical diagnosis. The authors proposed a concept of an integrated image diagnostic working station, in which a physician can look into all clinical images, can select any key image for diagnosis and can read it in detail. A prototype working station named ''Electronic Viewbox'' has been developed for this purpose. It has three distinctive features. 1. The stored images of a patient are shown at a glance. In order to achieve this function, each original image is attached to a small image, where the data are compressed to reserve the essence of the image, and many of these small images are displayed on a CRT screen. This small image is used as an index for picking up a key image in the archived clinical images. 2. The working station is compact enough to be set on a desk. Only two CRTs and a pointing device are assembled. These two CRT screens are used mutually for retrieving key images and for displaying the original images. 3. All operations can be done interactively using cursor and icons

Depth of origin and angular spectrum of sputtered atoms

International Nuclear Information System (INIS)

Vicanek, M.; Jimenez Rodriguez, J.J.; Sigmund, P.

1989-01-01

A theoretical analysis is presented of the depth of origin of atoms sputtered from a random target. The physical model aims at high energy sputtering under linear cascade conditions and assumes a dilute source of recoil atoms. The initial distribution of the recoils is assumed isotropic, and their energy distribution is E -2 like without an upper or lower cutoff. The scattering medium is either infinite or bounded by a plane surface. Atoms scatter according to the m=0 power cross section. Electronic stopping is ignored. The sputtered flux, differential in depth of origin, ejection energy and ejection angle has been evaluated by Monte Carlo simulation and by five distinct methods of solution of the linear Boltzmann equation reaching from continuous slowing down neglecting angular scattering to the P 3 approximation and a Gram-Charlier expansion going over spatial moments. The continuous slowing down approximation used in previous work leads to results that are identical to those found from a scheme that only ignores angular scattering but allows for energy loss straggling. Moreover, these predictions match more closely with the Monte Carlo results than any of the approximate analytical schemes that take account of angular scattering. The results confirm the common assertion that the depth of origin of sputtered atoms is determined mainly by the stopping of low energy recoil atoms. The effect of angular scattering turns out to be astonishingly small. The distributions in depth of origin, energy, and angle do not depend significantly on whether the scattering medium is a halfspace or an infinite medium with a reference plane. The angular spectrum comes out only very slightly over cosine from the model as it stands, in agreement with previous experience, but comments are made on essential features that are not incorporated in the physical model but might influence the angular spectrum.

Origins and development of the Cauchy problem in general relativity

International Nuclear Information System (INIS)

Ringström, Hans

2015-01-01

The seminal work of Yvonne Choquet-Bruhat published in 1952 demonstrates that it is possible to formulate Einstein's equations as an initial value problem. The purpose of this article is to describe the background to and impact of this achievement, as well as the result itself. In some respects, the idea of viewing the field equations of general relativity as a system of evolution equations goes back to Einstein himself; in an argument justifying that gravitational waves propagate at the speed of light, Einstein used a special choice of coordinates to derive a system of wave equations for the linear perturbations on a Minkowski background. Over the following decades, Hilbert, de Donder, Lanczos, Darmois and many others worked to put Einstein's ideas on a more solid footing. In fact, the issue of local uniqueness (giving a rigorous justification for the statement that the speed of propagation of the gravitational field is bounded by that of light) was already settled in the 1930s by the work of Stellmacher. However, the first person to demonstrate both local existence and uniqueness in a setting in which the notion of finite speed of propagation makes sense was Yvonne Choquet-Bruhat. In this sense, her work lays the foundation for the formulation of Einstein's equations as an initial value problem. Following a description of the results of Choquet-Bruhat, we discuss the development of three research topics that have their origin in her work. The first one is local existence. One reason for addressing it is that it is at the heart of the original paper. Moreover, it is still an active and important research field, connected to the problem of characterizing the asymptotic behaviour of solutions that blow up in finite time. As a second topic, we turn to the questions of global uniqueness and strong cosmic censorship. These questions are of fundamental importance to anyone interested in justifying that the Cauchy problem makes sense globally. They are

More than 40 years ago, Baddeley and Hitch (1974) published an article with a wealth of experimentation and theorization on working memory, the small amount of information held in mind and often used within cognitive processes such as language comprehension and production, reasoning, and problem solving. We honor this seminal accomplishment in the present special issue, and take this opportunity to provide an introduction to our perspectives on the origin of the theory of working memory, how it has affected our work, what may be coming in the near future, and how the research articles in the present issue contribute to several related themes within the clearly thriving field of working memory.

On ‘lost’ indigenous etymological origins with the specific case of the name Ameiva

Abstract Modern biology builds upon the historic exploration of the natural world. Recognizing the origin of a species’ name is one path to honor the historic exploration and description of the natural world and the indigenous peoples that lived closely with organisms prior to their description. While digitization of historic papers catalogued in databases such as the Biodiversity Heritage Library (BHL) allows for searching of the first use and origin of names, the rapid pace of taxonomic publishing can occlude a thorough search for etymologies. The etymological origin of the genus name Ameiva is one such case; while unattributed in multiple recent works, it is of Tupí language origin. The first description was in the Historiae Rerum Naturalium Brasiliae by George Marcgrave (1648). Ameiva was the name used by Marcgrave’s Amerindian hosts in 17th century Dutch Brazil, where local people spoke the now extinct language Tupí. The Tupí origin was not lost, however, until as recently as the 2000s. Herein, the pre- and post-Linnaean use of the name Ameiva is traced and when the name is attributed to the Tupí language and to Marcgrave through time it is noted.

Preparation Femtosecond Laser Prevention for the Cold-Worked Stress Corrosion Crackings on Reactor Grade Low Carbon Stainless Steel

CERN Document Server

John Minehara, Eisuke

2004-01-01

We report here that the femtosecond lasers like low average power Ti:Sapphire lasers, the JAERI high average power free-electron laser and others could peel off and remove two stress corrosion cracking (SCC) origins of the cold-worked and the cracking susceptible material, and residual tensile stress in hardened and stretched surface of low-carbon stainless steel cubic samples for nuclear reactor internals as a proof of principle experiment except for the third origin of corrosive environment. Because a 143 °C and 43% MgCl2 hot solution SCC test was performed for the samples to simulate the cold-worked SCC phenomena of the internals to show no crack at the laser-peered off strip on the cold-worked side and ten-thousands of cracks at the non-peeled off on the same side, it has been successfully demonstrated that the femtosecond lasers could clearly remove the two SCC origins and could resultantly prevent the cold-worked SCC.

Social work is a core health profession with origins deeply connected to the development of contemporary public health in the United States. Today, many of the nation’s 600 000 social workers practice broadly in public health and in other health settings, drawing on a century of experience in combining clinical, intermediate, and population approaches for greater health impact. Yet, the historic significance of this long-standing interdisciplinary collaboration—and its current implications—remains underexplored in the present era. This article builds on primary and contemporary sources to trace the historic arc of social work in public health, providing examples of successful collaborations. The scope and practices of public health social work practice are explored, and we articulate a rationale for an expanded place for social work in the public health enterprise. PMID:29236533

Les origines de l’entrepreneur schumpétérien The Origins of the Schumpeterian Entrepreneur

Directory of Open Access Journals (Sweden)

Jean-Jacques Gislain

2012-11-01

Full Text Available Cet article examine les deux origines, logique dans la théorie économique et historique dans l’histoire de la pensée économique, de l’entrepreneur chez J. A. Schumper. L’origine logique réside dans la nécessité analytique de construire un « type entrepreneur », comme type particulier d’agent économique, pour rendre intelligible le processus de transformation économique. Ce type permet le passage de l’analyse statique, le circuit walrasien, à celle dynamique de l’évolution économique. L’origine historique de ce type entrepreneur ne fait pas de Schumpeter un auteur aussi original que l’on pourrait le penser. Quelques années avant, de nombreux auteurs importants, et bien connus de Schumper, avaient déjà proposé des descriptions de l’entrepreneur très proches de celle de Schumpeter. Parmi ceux-ci, Max Weber, Werner Sombart, Alfred Marshall, Paul Leroy-Beaulieu et Friedrich von Wieser sont ici étudiés.This article examines both origins, logic in the economic theory and historic in the history of the economic thought, of the Schumpeterian entrepreneur. The logical origin lies in the analytical necessity of building a "typify entrepreneur", as particular type of economic agent, to make understandable the process of economic transformation. This type allows the passage of the static analysis, the walrasian circuit, that dynamics of the economic evolution. The historic origin of this type entrepreneur does not make Schumpeter a so original author as we could think of it. Some years before, numerous important authors, and known well by Schumper, had already proposed the descriptions of the entrepreneur very close to that of Schumpeter. Among these, Max Weber, Werner Sombart, Alfred Marshall, Paul Leroy-Beaulieu and Friedrich von Wieser are studied here.

Comparison of acoustic fields produced by the original and upgraded HM-3 lithotripter

Science.gov (United States)

Zhou, Yufeng; Zhu, Songlin; Dreyer, Thomas; Liebler, Marko; Zhong, Pei

2003-10-01

To reduce tissue injury in shock wave lithotripsy (SWL) while maintaining satisfactory stone comminution, an original HM-3 lithotripter was upgraded by a reflector insert to suppress large intraluminal bubble expansion, which is a primary mechanism of vascular injury in SWL. The pressure waveforms produced by the original and upgraded HM-3 lithotripter were measured by using a fiber optical probe hydrophone (FOPH), which was scanned both along and transverse to the lithotripter axis at 1-mm step using a computer-controlled 3-D positioning system. At F2, the pressure waveform produced by the upgraded HM-3 lithotripter at 22 kV has a distinct dual-pulse structure, with a leading shock wave of ~45 MPa from the reflector insert and a 4-μs delayed second pulse of ~15 MPa reflected from the uncovered bottom surface of the original HM-3 reflector. The beam sizes of the original and upgraded HM-3 lithotripter are comparable in both axial and lateral directions. The pressure waveforms measured at the reflector aperture will be used as input to the KZK equation to predict the lithotripter shock wave at F2. Furthermore, bubble dynamics predicted by the Gilmore model will be compared with experimental observation by high-speed imaging. [Work supported by NIH.

Full Text Available Due to digitisation of traditional documents new collections of electronic publications/resources are formed. The article deals with the process of planning of digitisation of library materials on traditional media, accompanying decisions and procedures, as well as methods of storage and preservation of digitised materials, the impact of target public on the decision about what to digitise and the questions of copyright. Acquisition and preservation of new media has an important influence on the work of libraries, especially on collection development. Parallel to these changes new technical terms develop, as for example information resources management.In the introduction, the author actualise the thought of Walter Benjamin on the impact of reproduction techniques on the status of original documents and on the separation of tradition from what was reproduced. The question whether digitisation changes the principles of national libraries underlying the preservation of national cultural heritage is raised.

Ethics of prayer and work in 1 and 2 Thessalonians

Jean-Claude Loba-Mkole

2013-11-01

Full Text Available This article raises the question of the balance between prayer and work. This topic is discussed through an intercultural approach of Paul’s recommendation about praying and working without ceasing (1 Th 1:9; 3:10. The main hypothesis postulates that constant prayer and work are associated with the concepts of thanksgiving (words of the εὐχαριστ-lemma and exemplarity. It is argued that Pauline recommendations about praying and working without ceasing prove to be supported not only by an original biblical culture, but also by a church culture as well as a currently emerging African culture.

Simulation of the energy spectra of original versus recombined H2+ molecular ions transmitted through thin foils

International Nuclear Information System (INIS)

Barriga-Carrasco, Manuel D.; Garcia-Molina, Rafael

2004-01-01

This work presents the results of computer simulations for the energy spectra of original versus recombined H 2 + molecular ions transmitted through thin amorphous carbon foils, for a broad range of incident energies. A detailed description of the projectile motion through the target has been done, including nuclear scattering and Coulomb repulsion as well as electronic self-retarding and wake forces; the two latter are calculated in the dielectric formalism framework. Differences in the energy spectra of recombined and original transmitted H 2 + molecular ions clearly appear in the simulations, in agreement with the available experimental data. Our simulation code also differentiates the contributions due to original and to recombined H 2 + molecular ions when the energy spectra contain both contributions, a feature that could be used for experimental purposes in estimating the ratio between the number of original and recombined H 2 + molecular ions transmitted through thin foils

An Attempt at Reconstruction of the Original Colour Scheme of the Paper Ground of Witkacy’s Portraits

Directory of Open Access Journals (Sweden)

Beata Zgodzińska

2010-01-01

Full Text Available In the years 2005–2006 at a Restoration Workshop of Muzeum Pomorza Środkowego [Museum of Central Pomerania] in Słupsk, Witkacy’s portraits were framed in a new passe partout and glass pane. Based on the photographs taken then of fragments on which the colour of the paper ground was preserved, a computer reconstruction of the original colour of the paper was made. Comparison of the portraits with their probable original versions allows to risk a claim that nowadays we have to do with totally different pictures. The colour of the paper has changed considerably, e.g. from its initial violet it has turned into grey-beige. Equally big changes can be observed between the reverse and the face. When framing the portrait, restorers found an unfinished portrait on the reverse. The examples presented in this work show how important for the knowledge of the artist and his work is drawing attention to a single work of art, which is best to study directly and not through its reproductions or studies on it.

Full Text Available Objective: To outline the origin and evolution of the work of Community Health Agents (ACS in Ceará. Data synthesis: A review of the literature pertaining to the subject and interviews with technicians from Ceará State Health Secretariat (SESA-Ce and from Ceará Public Health School (ESP-Ce were the sources of the data collected. Initially, we discussed the social and political scenario in which primary health care developed in the state, emphasizing the evolution of socioeconomic indicators and infant health. Then, we did a brief exposure of health care model and from then on, we focused on the Community Health Agent Program, since its origin as an emergency program, its integration into the Family Health Strategy, the repercussions of this insertion in the work of the Community Health Agent and the need for training of ACS. Conclusion: A discussion on the process of training of ACS was presented seeking dialogue with the necessary training in face of new health needs of the population, and most of all, strengthening the role of ACS as a mediator between families and health professionals at local level.

Origin of tektites

Science.gov (United States)

O'Keefe, John A.

1994-01-01

The origin of tektites has been obscure because of the following dilemma. The application of physical principles to the data available on tektites points strongly to origin from one or more lunar volcanoes; but few glasses of tektite composition have hitherto been reported from the lunar samples. Instead, the lunar silicic glasses consist chiefly of a material very rich in K2O and poor in MgO. The ratio of K2O/MgO is higher in these glasses than in any tektites reported. The solution of the dilemma seems to come from the study of some recently discovered terrestrial deposits of tektite glass with high values of K2O/MgO at the Cretaceous Tertiary boundary. These glasses are found to be very vulnerable to crystallization into sandine or to alteration to smectite. These end products are known and are more abundant than any terrestrial deposits of tektite glass. It seems possible that, in fact, the moon produces tektite glass, mostly of the high K2O-low MgO type; but on Earth these deposits are destroyed. The much less abundant deposits with lower K and higher Mg are observed because they survive. Other objections to the lunar origin hypothesis appear to be answerable.

2009-01-01

This study estimated the prevalence of chronic back pain among migrant farmworker family members and identified associated work and non-work variables. Migrant farmworkers (n = 390 from 267 families) from Starr County, Texas were interviewed in their home once a year for 2 years. The original survey included items measuring demographics, smoking, sleep, farm work, and chronic back pain. For this cross-sectional analysis, multi-level logistic regression was used to identify associated work and other variables associated with chronic back pain while accounting for intraclass correlations due to repeated measures and multiple family members. The prevalence of chronic back pain during the last migration season ranged from 9.5% among the youngest children to 33.3% among mothers. Variables significantly associated with chronic back pain were age (odds ratio [OR], 1.03, per year increase), depressive symptoms while migrating (OR, 8.72), fewer than 8 hours of sleep at home in Starr County (OR, 2.26), fairly bad/very bad quality of sleep while migrating (OR, 3.25), sorting crops at work (OR, 0.18), and working tree crops (OR, 11.72). The role of work exposures, depressive symptoms, and sleep in chronic back pain among farmworkers warrants further examination. Refinements in outcome and exposure assessments are also needed given the lack of a standardized case definition and the variety of tasks and crops involved in farm work in the United States.

Parental care is a defining feature of animal breeding systems. We now know that both basic life-history characteristics and ecological factors influence the evolution of care. However, relatively little is known about how these factors interact to influence the origin and maintenance of care. Here, we expand upon previous work and explore the relationship between basic life-history characteristics (stage-specific rates of mortality and maturation) and the fitness benefits associated with the origin and the maintenance of parental care for two broad ecological scenarios: the scenario in which egg survival is density dependent and the case in which adult survival is density dependent. Our findings suggest that high offspring need is likely critical in driving the origin, but not the maintenance, of parental care regardless of whether density dependence acts on egg or adult survival. In general, parental care is more likely to result in greater fitness benefits when baseline adult mortality is low if 1) egg survival is density dependent or 2) adult mortality is density dependent and mutant density is relatively high. When density dependence acts on egg mortality, low rates of egg maturation and high egg densities are less likely to lead to strong fitness benefits of care. However, when density dependence acts on adult mortality, high levels of egg maturation and increasing adult densities are less likely to maintain care. Juvenile survival has relatively little, if any, effect on the origin and maintenance of egg-only care. More generally, our results suggest that the evolution of parental care will be influenced by an organism's entire life history characteristics, the stage at which density dependence acts, and whether care is originating or being maintained.

Origin of solar radio waves

International Nuclear Information System (INIS)

Olmr, J.

1977-01-01

Solar radiowave radiation amounts to about 10 -7 of the total solar radiation. The solar atmosphere emits radiation of different wavelengths from a fraction of nanometer to kilometer waves. The solar radiowaves are of thermal origin and except for neutral hydrogen emission and solid body radio emission their emission always results from free electrons. The radiowave radiation active components were classified in several types, such as noise storms, flashes, flares, continuum, and flashes lasting for several minutes. The respective types are discussed and their origins shown. The mechanisms are described permitting the formation of radio waves of nonthermal origin, i.e., plasma oscillations, gyromagnetic emission, synchrotron and Cherenkov radiations. (J.P.)

The life and works of John Napier

CERN Document Server

Rice, Brian; Corrigan, Alexander

2017-01-01

For the first time, all five of John Napier’s works have been brought together in English in a single volume, making them more accessible than ever before. His four mathematical works were originally published in Latin: two in his lifetime (1550–1617), one shortly after he died, and one over 200 years later. The authors have prepared three introductory chapters, one covering Napier himself, one his mathematical works, and one his religious work. The former has been prepared by one of Napier’s descendants and contains many new findings about Napier’s life to provide the most complete biography of this enigmatic character, whose reputation has previously been overshadowed by rumour and speculation. The latter has been written by an academic who was awarded a PhD for his thesis on Napier at the University of Edinburgh, and it provides the most lucid and coherent coverage available of this abstruse and little understood work. The chapter on Napier’s mathematical texts has been authored by an experienced...

Healthcare quality improvement work: a professional employee perspective.

Gadolin, Christian; Andersson, Thomas

2017-06-12

Purpose The purpose of this paper is to describe and analyze conditions that influence how employees engage in healthcare quality improvement (QI) work. Design/methodology/approach Qualitative case study based on interviews ( n=27) and observations ( n=10). Findings The main conditions that influence how employees engage in healthcare QI work are professions, work structures and working relationships. These conditions can both prevent and facilitate healthcare QI. Professions and work structures may cement existing institutional logics and thus prevent employees from engaging in healthcare QI work. However, attempts to align QI with professional logics, together with work structures that empower employees, can make these conditions increase employee engagement, which can be accomplished through positive working relationships that foster institutional work, which bridge different competing institutional logics, making it possible to overcome barriers that professions and work structures may constitute. Practical implications Understanding the conditions that influence how employees engage in healthcare QI work will make initiatives more likely to succeed. Originality/value Healthcare QI has mainly been studied from an implementer perspective, and employees have either been neglected or seen as passive resisters. Weak employee perspectives make healthcare QI research incomplete. In our research, healthcare QI work is studied closely at the actor level to understand healthcare QI from an employee perspective.

DNA replication origins-where do we begin?

Science.gov (United States)

Prioleau, Marie-Noëlle; MacAlpine, David M

2016-08-01

For more than three decades, investigators have sought to identify the precise locations where DNA replication initiates in mammalian genomes. The development of molecular and biochemical approaches to identify start sites of DNA replication (origins) based on the presence of defining and characteristic replication intermediates at specific loci led to the identification of only a handful of mammalian replication origins. The limited number of identified origins prevented a comprehensive and exhaustive search for conserved genomic features that were capable of specifying origins of DNA replication. More recently, the adaptation of origin-mapping assays to genome-wide approaches has led to the identification of tens of thousands of replication origins throughout mammalian genomes, providing an unprecedented opportunity to identify both genetic and epigenetic features that define and regulate their distribution and utilization. Here we summarize recent advances in our understanding of how primary sequence, chromatin environment, and nuclear architecture contribute to the dynamic selection and activation of replication origins across diverse cell types and developmental stages. © 2016 Prioleau and MacAlpine; Published by Cold Spring Harbor Laboratory Press.

Full Text Available Origin of samples of Cannabis sativa through insect fragments associated with compacted hemp drug in South America. Insects associated with a seizure of Cannabis sativa L. may indicate the origin of the illicit drug. Nevertheless, no work regarding this subject has been previously published for South America. In the present investigation, seven kilograms of vegetal material (C. sativa were inspected for insect fragments. Three species were identified and used to test the origin of the seizure of cannabis plant material: Euschistus heros (Fabricius, 1794, Thyanta perditor (Fabricius, 1794 (Heteroptera, Pentatomidae, and Cephalotes pusillus (Klug, 1824 (Hymenoptera, Formicidae. These insect species restricted the geographic origin of the drug to the Neotropical region, and their distribution patterns showed an overlap of the State of Mato Grosso (Brazil, Argentina, and Paraguay. Based on this information, two of the three major C. sativa growing areas in South America were excluded: (1 the Colombian territory and (2 northeastern Brazil.

The Origin of Sequential Chromospheric Brightenings

Science.gov (United States)

Kirk, M. S.; Balasubramaniam, K. S.; Jackiewicz, J.; Gilbert, H. R.

2017-06-01

Sequential chromospheric brightenings (SCBs) are often observed in the immediate vicinity of erupting flares and are associated with coronal mass ejections. Since their initial discovery in 2005, there have been several subsequent investigations of SCBs. These studies have used differing detection and analysis techniques, making it difficult to compare results between studies. This work employs the automated detection algorithm of Kirk et al. (Solar Phys. 283, 97, 2013) to extract the physical characteristics of SCBs in 11 flares of varying size and intensity. We demonstrate that the magnetic substructure within the SCB appears to have a significantly smaller area than the corresponding Hα emission. We conclude that SCBs originate in the lower corona around 0.1 R_{⊙} above the photosphere, propagate away from the flare center at speeds of 35 - 85 km s^{-1}, and have peak photosphere magnetic intensities of 148±2.9 G. In light of these measurements, we infer SCBs to be distinctive chromospheric signatures of erupting coronal mass ejections.

Origins the scientific story of creation

What is the nature of the material world? How does it work? What is the universe and how was it formed? What is life? Where do we come from and how did we evolve? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later. Chapter by chapter, it sets out the current state of scientific knowledge: the origins of space and time; energy, mass, and light; galaxies, stars, and our sun; the habitable earth, and complex life itself. Drawing together the physical and biological sciences, Baggott recounts what we currently know of our history, highlighting the questions science has yet to answer.

The Biblicism of the Korean Protestant churches: Its origin and early development

Full Text Available The purpose of this article is to clarify the origin and early stages of the Biblicism of the Korean Protestant churches in general, and of the Presbyterian Church of Korea (PCK in particular. The Biblicism is very important for Korean Protestant churches, because it is believed to be a main cause of their unusual growth on the one hand, and on the other hand, of their Fundamentalism and many schisms in the post-liberation era. The article, in the beginning part, investigates the four crucial elements of Korean Biblicism and then examines how the four elements worked together to form a resilient Biblicism whose two distinctive theological forms were practical on the one hand, and dogmatic (fundamentalist, on the other. Among the four basic Biblicist elements, the first was the firm Biblicist theology of the early North American missionaries in Korea who tried to follow and flower their original, puritanical and Old Princeton theology in Korea. The second was Korean Protestants’ original, Neo-Confucian biblicism, which facilitated them to readily accept the missionaries’ Biblicist teachings of the Bible. The third element was the so-called Nevius [Mission] Methods, which emphasised simplistic Biblicist Bible studies, and offered both opportunities of learning and ways to become meaningful leaders in their communities. The fourth and last element was the Biblicist creed of PCK, which became the fundamentalist weapon against its modernist or liberalist wing. To sum up, Korean Biblicism has been the result of those four Biblicist elements working together. The Korean Biblicism was developed into two more or less different positions; the one being practical, exemplified by Rev. Samuel A. Moffett; and the other, dogmatic and fundamentalist, represented by Rev. Dr W.D. Reynolds.

2012-01-01

Full Text Available The study presented in this paper deals with the effects of experiences with father in the family of origin on the fathering role in the family of procreation. The results of the studies so far point to great importance of such experiences in parental role modelling, while recent approaches have suggested the concept of introjected notion or an internal working model of the fathering role as the way to operationalise the transgenerational transfer. The study included 247 two-parent couple families whose oldest child attended preschool education. Fathers provided information on self-assessed involvement via the Inventory of father involvement, while both fathers and mothers gave information on introjected experiences from the family of origin via the inventory Presence of the father in the family of origin. It was shown that father’s experiences from the family of origin had significant direct effects on his involvement in child-care. Very important experiences were those of negative emotional exchange, physical closeness and availability of the father, as well as beliefs about the importance of the father as a parent. Although maternal experiences from the family of origin did not contribute significantly to father involvement, shared beliefs about father’s importance as a parent in the parenting alliance had an effect on greater involvement in child-care. The data provide confirmation of the hypotheses on modelling of the fathering role, but also open the issue of the factor of intergenerational maintenance of traditional forms of father involvement in families in Serbia.

2017-06-19

Purpose The purpose of this paper is to explore work motivation among professionals at well-functioning primary healthcare centers subject to a national healthcare reform which include financial incentives. Design/methodology/approach Five primary healthcare centers in Sweden were purposively selected for being well-operated and representing public/private and small/large units. In total, 43 interviews were completed with different medical professions and qualitative deductive content analysis was conducted. Findings Work motivation exists for professionals when their individual goals are aligned with the organizational goals and the design of the reform. The centers' positive management was due to a unique combination of factors, such as clear direction of goals, a culture of non-hierarchical collaboration, and systematic quality improvement work. The financial incentives need to be translated in terms of quality patient care to provide clear direction for the professionals. Social processes where professionals work together as cohesive groups, and provided space for quality improvement work is pivotal in addressing how alignment is created. Practical implications Leaders need to consistently translate and integrate reforms with the professionals' drives and values. This is done by encouraging participation through teamwork, time for structured reflection, and quality improvement work. Social implications The design of the reforms and leadership are essential preconditions for work motivation. Originality/value The study offers a more complete picture of how reforms are managed at primary healthcare centers, as different medical professionals are included. The value also consists of showing how a range of aspects combine for primary healthcare professionals to successfully manage external reforms.

Implications of the Deep Minimum for Slow Solar Wind Origin

Science.gov (United States)

Antiochos, S. K.; Mikic, Z.; Lionello, R.; Titov, V. S.; Linker, J. A.

2009-12-01

The origin of the slow solar wind has long been one of the most important problems in solar/heliospheric physics. Two observational constraints make this problem especially challenging. First, the slow wind has the composition of the closed-field corona, unlike the fast wind that originates on open field lines. Second, the slow wind has substantial angular extent, of order 30 degrees, which is much larger than the widths observed for streamer stalks or the widths expected theoretically for a dynamic heliospheric current sheet. We propose that the slow wind originates from an intricate network of narrow (possibly singular) open-field corridors that emanate from the polar coronal hole regions. Using topological arguments, we show that these corridors must be ubiquitous in the solar corona. The total solar eclipse in August 2008, near the lowest point of the Deep Minimum, affords an ideal opportunity to test this theory by using the ultra-high resolution Predictive Science's (PSI) eclipse model for the corona and wind. Analysis of the PSI eclipse model demonstrates that the extent and scales of the open-field corridors can account for both the angular width of the slow wind and its closed-field composition. We discuss the implications of our slow wind theory for the structure of the corona and heliosphere at the Deep Minimum and describe further observational and theoretical tests. This work has been supported by the NASA HTP, SR&T, and LWS programs.

Near vision correction and work productivity among textile workers

2016-11-01

Full Text Available Purpose: Uncorrected presbyopia (near vision impairment is prevalent in approximately 517 million people worldwide; this prevalence ranges from 30% to 80% in Africa. Good near vision is needed for a range of tasks; therefore, uncorrected presbyopia can negatively affect the quality of life of individuals, impact families and society, and potentially have negative implications on employment and labour work productivity. This study aimed to determine the impact of near vision correction on the work productivity of clothing factory workers. Methods: We conducted a cross-sectional study and sampled all workers who were aged 40 years and older and who performed near vision tasks (e.g. machinist, cutter, zip sewer, clothing pressers and quality controllers in seven clothing factories. We included workers who were employed for at least 3 months and whose uncorrected near visual acuity could be improved and corrected to better than 6/9 with spectacle correction. Workers were provided with near vision spectacles, and changes in their work productivity were evaluated after 6 months, using the factories’ output records as an indicator for measurement. Results: The final sample comprised 268 individuals, with 56% of African origin (n = 151 and 49% (n = 115 Indian origin. There were mainly females (94% in the sample, and the average age was 48 years (± 5.5 years, range 40–62 years. The overall post-correction mean production score (70.5 [SD ± 19.9] was significantly higher than the overall pre-correction mean production score (67.0 [SD ±20.3] (p < 0.001. The average change in production score was 3.5 (95% confidence interval [CI] 2.7–4.3, and the percent difference was 6.4% (95% CI 5.2–7.7. The increase in work productivity was significant for individuals of African (p < 0.001 and Indian origins (p < 0.001 but not for those of mixed race (p = 0.364; n = 2. Post-correction, the production scores of women increased significantly by 6.6% (95% CI 5.3�

Ethnic Identity and Gender as Moderators of the Association between Discrimination and Academic Adjustment among Mexican-origin Adolescents

Umaña-Taylor, Adriana J.; Wong, Jessie J.; Gonzales, Nancy A.; Dumka, Larry E.

2011-01-01

Existing work has identified perceived discrimination as a risk factor that may contribute to the relatively poorer academic outcomes exhibited by Mexican-origin adolescents in the U.S. The current study examined the longitudinal associations among perceived discrimination and three indices of adolescent adjustment in the school setting (i.e., grade point average, teacher reports of externalizing, adolescents’ deviant peer associations) among 178 Mexican-origin adolescents (53% female). Ethnic identity affirmation was examined as a protective factor expected to reduce the negative effects of discrimination on adolescents’ adjustment, and gender was examined as a potential moderator of the associations of interest. Findings indicated that the deleterious effects of discrimination on adolescents’ adjustment in school were particularly salient for Mexican-origin male adolescents. Importantly, ethnic identity affirmation emerged as a protective factor for Mexican-origin male adolescents by buffering the negative effects of discrimination on their externalizing behaviors in school.

In 1964-1974, the German artist Max Ernst created, with the help of two friends, a series of works (books, movie, and paintings) related to the astronomer Wilhelm Tempel. Mixing actual texts by Tempel and artistic features, this series pays homage to the astronomer by recalling his life and discoveries. Moreover, the core of the project, the book Maximiliana or the Illegal Practice of Astronomy, actually depicts the way science works, making this work of art a most original tribute to a scientist.

Working Memory in Written Composition: An Evaluation of the 1996 Model

Directory of Open Access Journals (Sweden)

Ronald T. Kellogg, , , &

2013-10-01

Full Text Available A model of how working memory, as conceived by Baddeley (1986, supports the planning of ideas, translating ideas into written sentences, and reviewing the ideas and text already produced was proposed by Kellogg (1996. A progress report based on research from the past 17 years shows strong support for the core assumption that planning, translating, and reviewing are all dependent on the central executive. Similarly, the translation of ideas into a sentence does in fact require also verbal working memory, but the claim that editing makes no demands on the phonological loop is tenuous. As predicted by the model, planning also engages the visuo-spatial sketchpad. However, it turns out to do so only in planning with concrete concepts that elicit mental imagery. Abstract concepts do not require visuo-spatial resources, a point not anticipated by the original model. Moreover, it is unclear the extent to which planning involves spatial as opposed to visual working memory. Contrary to Baddeley’s original model, these are now known to be independent stores of working memory; the specific role of the spatial store in writing is uncertain based on the existing literature. The implications of this body of research for the instruction of writing are considered in the final section of the paper.

Employment and work-related issues in cancer survivors.

Mehnert, Anja

2011-02-01

Purpose of this systematic literature review was to identify current knowledge about employment in cancer survivors. Sixty-four studies met inclusion criteria that were original papers published between 01/2000 and 11/2009. Overall, 63.5% of cancer survivors (range 24-94%) returned to work. The mean duration of absence from work was 151 days. Factors significantly associated with a greater likelihood of being employed or return to work were perceived employer accommodation, flexible working arrangements, counseling, training and rehabilitation services, younger age and cancer sites of younger individuals, higher levels of education, male gender, less physical symptoms, lower length of sick leave and continuity of care. Cancer survivors had a significantly increased risk for unemployment, early retirement and were less likely to be re-employed. Between 26% and 53% of cancer survivors lost their job or quit working over a 72-month period post diagnosis. Between 23% and 75% of patients who lost their job were re-employed. A high proportion of patients experienced at least temporary changes in work schedules, work hours, wages and a decline in work ability compared to non-cancer groups.

1997-10-01

To determine the best projection angles for imaging the renal artery origins in profile. A mathematical model of the anatomy at the renal artery origins in the transverse plane was used to analyze the amount of aortic lumen that projects over the renal artery origins at various projection angles. Computed tomographic (CT) angiographic data about the location of 400 renal artery origins in 200 patients were statistically analyzed. In patients with an abdominal aortic diameter no larger than 3.0 cm, approximately 0.5 mm of the proximal part of the renal artery and origin may be hidden from view if there is a projection error of +/-10 degrees from the ideal image. A combination of anteroposterior and 20 degrees and 40 degrees left anterior oblique projections resulted in a 92% yield of images that adequately profiled the renal artery origins. Right anterior oblique projections resulted in the least useful images. An error in projection angle of +/-10 degrees is acceptable for angiographic imaging of the renal artery origins. Patients sex, site of interest (left or right artery), and local diameter of the abdominal aorta are important factors to consider.

Brahms was originally conceived as a business process design tool that simulates work practices, including social systems of work. We describe our modeling and simulation method for mission operations work systems design, based on a research case study in which we used Brahms to design mission operations for a proposed discovery mission to the Moon. We then describe the results of an actual method application project-the Brahms Mars Exploration Rover. Space mission operations are similar to operations of traditional organizations; we show that the application of Brahms for space mission operations design is relevant and transferable to other types of business processes in organizations.

Analysis of Change Orders in Geotechnical Engineering Work at INDOT

OpenAIRE

Duvvuru Mohan, Varenya Kumar; Prezzi, Monica; McCullouch, Bob

2011-01-01

Change orders represent a cost to the State and to tax payers that often extremely large because contractors tend to charge very large amounts to any additional work that deviates from the work that was originally planned. Therefore, efforts must be made to reduce the occurrence of change orders in order to provide significant cost savings to the state of Indiana and save taxpayer dollars. The proposed research, in this context, developed a set of guidelines to allow the geotechnical office o...

Francois Garin: Pioneer work in catalysis through synchrotron radiation

International Nuclear Information System (INIS)

Bazin, Dominique

2014-01-01

Starting from the late seventies, the progressively increased availability of beamlines dedicated to X-ray absorption spectroscopy allowed the execution of experiments in chemistry. In this manuscript, I describe the contribution of Francois Garin at the frontier of heterogeneous catalysis and synchrotron radiation. Working at LURE as a scientific in charge of a beamline dedicated to X-ray absorption spectroscopy during almost twenty years and thus, having the opportunity to discuss with research groups working in heterogeneous catalysis in Europe as well as in the United States, it was quite easy to show that his work is clearly at the origin of current research in heterogeneous catalysis, not only in France, but in different synchrotron radiation centres.

Full text: Russian Federation Minister of Atomic Energy Alexander Rumyantsev, United States Secretary of Energy Spencer Abraham and Director General of the International Atomic Energy Agency (IAEA) Mohamed ElBaradei met in Vienna on 16 September 2002 to review the status of the Trilateral Initiative and agree on its future direction. The parties concluded that the task entrusted to the Trilateral Initiative Working Group in 1996 has been fulfilled. The work completed has demonstrated practical approaches for IAEA verification of weapon-origin fissile material designated as released from defence programmes in classified forms or at certain sensitive facilities. The work included the examination of technical, legal and financial issues associated with such verification. The removal of weapon-origin fissile material from defence programmes of the Russian Federation and the United States is in furtherance of the commitment to disarmament steps undertaken by the two States pursuant to Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). IAEA verification of the materials declared excess to nuclear weapons programmes and made subject to this Initiative would build international confidence that this material will never again be used in nuclear weapons. Minister Rumyantsev, Secretary Abraham and Director General ElBaradei recognized the value of the groundbreaking work completed over the last six years. Building on the work completed, they directed the technical experts to begin without delay discussions on future possible cooperation within the trilateral format. Minister Rumyantsev, Secretary Abraham and Director General ElBaradei agreed that the Principals would meet again in September 2003 to review progress within the trilateral format. (IAEA)

2009-01-01

By comprehensive analysis on informations of regional geology and evaluating drillhole works of uranium resources in the southeast of Songliao basin, lithofacies-palaeogeography features, lithologies and sandbody characteristics of target layes in Quantou formation, Yaojia formation and Sifangtai formation have been basically found out. By research on geochemical environment of rocks in target layez, types of original geochemistry and epigenetic alteration have been identified and classified. The types of original geochemistry have been divided into types of original oxidation and original reduction, and the types of epigenetic alteration have been divided into types of reduction by oil-gas and coalbed gas and epigenetic oxidation. By comparative study on mineral and chemical characteristics of original geochemistry and epigenetic oxidation, identification marks for oil-gas and coalbed gas reduced epigenetic oxidation have been proposed. It is proposed that uranium was strongly pre-concentrated in original sandstone that bearing carboniferous matter, and reduction by oil-gas and coalbed gas made uranium superimpose and concentrate in alterated rocks.

Population-Level Density Dependence Influences the Origin and Maintenance of Parental Care.

Directory of Open Access Journals (Sweden)

Elijah Reyes

Full Text Available Parental care is a defining feature of animal breeding systems. We now know that both basic life-history characteristics and ecological factors influence the evolution of care. However, relatively little is known about how these factors interact to influence the origin and maintenance of care. Here, we expand upon previous work and explore the relationship between basic life-history characteristics (stage-specific rates of mortality and maturation and the fitness benefits associated with the origin and the maintenance of parental care for two broad ecological scenarios: the scenario in which egg survival is density dependent and the case in which adult survival is density dependent. Our findings suggest that high offspring need is likely critical in driving the origin, but not the maintenance, of parental care regardless of whether density dependence acts on egg or adult survival. In general, parental care is more likely to result in greater fitness benefits when baseline adult mortality is low if 1 egg survival is density dependent or 2 adult mortality is density dependent and mutant density is relatively high. When density dependence acts on egg mortality, low rates of egg maturation and high egg densities are less likely to lead to strong fitness benefits of care. However, when density dependence acts on adult mortality, high levels of egg maturation and increasing adult densities are less likely to maintain care. Juvenile survival has relatively little, if any, effect on the origin and maintenance of egg-only care. More generally, our results suggest that the evolution of parental care will be influenced by an organism's entire life history characteristics, the stage at which density dependence acts, and whether care is originating or being maintained.

Representation of photon limited data in emission tomography using origin ensembles

Representation and reconstruction of data obtained by emission tomography scanners are challenging due to high noise levels in the data. Typically, images obtained using tomographic measurements are represented using grids. In this work, we define images as sets of origins of events detected during tomographic measurements; we call these origin ensembles (OEs). A state in the ensemble is characterized by a vector of 3N parameters Y, where the parameters are the coordinates of origins of detected events in a three-dimensional space and N is the number of detected events. The 3N-dimensional probability density function (PDF) for that ensemble is derived, and we present an algorithm for OE image estimation from tomographic measurements. A displayable image (e.g. grid based image) is derived from the OE formulation by calculating ensemble expectations based on the PDF using the Markov chain Monte Carlo method. The approach was applied to computer-simulated 3D list-mode positron emission tomography data. The reconstruction errors for a 10 000 000 event acquisition for simulated ranged from 0.1 to 34.8%, depending on object size and sampling density. The method was also applied to experimental data and the results of the OE method were consistent with those obtained by a standard maximum-likelihood approach. The method is a new approach to representation and reconstruction of data obtained by photon-limited emission tomography measurements.

Thrust tectonics in crystalline domains: The origin of a gneiss dome

Science.gov (United States)

Greiling, R. O.

1997-12-01

Structural geological field work, microscopic and magnetic fabric studies have been applied in order to assess the structural origin of a gneiss dome, based on a regional example from the Neoproterozoic Pan-African Belt of NE Africa, the Wadi Hafafit Culmination (WHC). The culmination is dominated by a number of major shear zones, which form both the boundaries between the gneissic core and surrounding low grade successions as well as those of minor structural units within the gneisses. These shear zones form a linked fault system, which, based on shear criteria, fault-bend fold and overall geometric interrelationships, can be classified as an antiformal stack. The relative age sequence of the shear zones/thrusts with the highest thrust oldest and the lowermost youngest points to a forward-propagating thrust system. This, together with the shear criteria, exclude an origin of the WHC as a metamorphic core complex, where the highest shear zone should be youngest. The geometry of the WHC antiformal stack is documented by maps and sections as well as section balancing and restoration. Microscopic work showed brittle deformation in feldspar and dynamic recrystallization in quartz ribbons. The asymmetry of the fabric confirmed the macroscopically determined shear sense. However, there is one example of an earlier, perhaps extensional shear movement. Mylonitic foliation and transport-parallel lineation have also been determined by magnetic fabric studies. The observations suggest that thrusts may cut across both previously folded crystalline rocks as well as homogeneous granitoid plutonic bodies. According to the regional tectonic picture the large-scale structure of the gneiss dome originated after a phase of (late-orogenic) extensional collapse. It is speculated that during late-orogenic cooling the upper part of the lithosphere was sufficiently strong to allow brittle thrusting whilst the lithosphere as a whole was still weak enough to allow large-scale compressional

This report summarizes a conference: “Early Origins of Child Obesity: Bridging Disciplines and Phases of Development”, held in Chicago on September 30–October 1, 2010. The conference was funded in part by the National Institutes of Health and the Williams Heart Foundation, to achieve the conference objective: forging a next-step research agenda related to the early origins of childhood obesity. This research agenda was to include working with an array of factors (from genetic determinants to societal ones) along a continuum from prenatal life to age 7, with an emphasis on how the developing child deals with the challenges presented by his/her environment (prenatal, parental, nutritional, etc.). The conference offered a unique opportunity to facilitate communication and planning of future work among a variety of researchers whose work separately addresses different periods in early life. Over the span of two days, speakers addressed existing, critical research topics within each of the most-studied age ranges. On the final day, workshops fostered the discussion needed to identify the highest priority research topics related to linking varied early factor domains. These are presented for use in planning future research and research funding. PMID:23443002

The divertor particle simulation code named PARASOL simulates open-field plasmas between divertor walls self-consistently by using an electrostatic PIC method and a binary collision Monte Carlo model. The PARASOL parallelized with MPI-1.1 for scalar parallel computer worked on Intel Paragon XP/S system. A system SGI Origin 3800 was newly installed (May, 2001). The parallel programming was improved at this switchover. As a result of the high-performance new hardware and this improvement, the PARASOL is speeded up by about 60 times with the same number of processors. (author)

Origin of the water drained by the tunnel Graton

Plata B, A.

1992-12-01

The research of the origin of the water drained by the Graton tunnel was attempted using isotope techniques. During the period of studies (April 1989-October 1992), four field work was executed to sample waters for chemistry, stable isotope and Tritium analysis, an to inject tracers and verify the possible infiltration from the Rimac and Blanco rivers to the tunnel. The results of the stable isotope analysis show that the water drained by the Graton tunnel comes from a basin around 300 meters above the average altitude of the basin where the Graton is located. The Tritium analysis show that the water is relatively modern. Using the model of total mixing, the residence times of the water drained at the km 0.5 and 2.5 are in the order to 45 years. The conductivities of the water of the tunnel is higher than the Rimac river ones because the influence of mine water. The chemical analysis of the water sampled at the downstream end of the tunnel, show that the conservative ions of the water kept almost constant during more than two years. The results of the work with artificial tracer show that there is no significant leakage from the Rimac and Blanco rivers to the Graton tunnel. So far, it can be concluded as a preliminary approach that the Graton tunnel drains relatively modern water originated in another basin. The hydrodynamics of the area of study seems to include a large storage on underground water in the system. The topography, geology and isotopic composition of the water samples, points to the upper Mantaro river basin as the possible source of part of the water drained by the Graton tunnel.

The origin of turtles: a paleontological perspective.

Science.gov (United States)

Joyce, Walter G

2015-05-01

The origin of turtles and their unusual body plan has fascinated scientists for the last two centuries. Over the course of the last decades, a broad sample of molecular analyses have favored a sister group relationship of turtles with archosaurs, but recent studies reveal that this signal may be the result of systematic biases affecting molecular approaches, in particular sampling, non-randomly distributed rate heterogeneity among taxa, and the use of concatenated data sets. Morphological studies, by contrast, disfavor archosaurian relationships for turtles, but the proposed alternative topologies are poorly supported as well. The recently revived paleontological hypothesis that the Middle Permian Eunotosaurus africanus is an intermediate stem turtle is now robustly supported by numerous characters that were previously thought to be unique to turtles and that are now shown to have originated over the course of tens of millions of years unrelated to the origin of the turtle shell. Although E. africanus does not solve the placement of turtles within Amniota, it successfully extends the stem lineage of turtles to the Permian and helps resolve some questions associated with the origin of turtles, in particular the non-composite origin of the shell, the slow origin of the shell, and the terrestrial setting for the origin of turtles. © 2015 Wiley Periodicals, Inc.

Work-based learning in health care organisations experienced by nursing staff: A systematic review of qualitative studies.

Science.gov (United States)

Nevalainen, Marja; Lunkka, Nina; Suhonen, Marjo

2018-03-01

The aim of this review is to systematically summarise qualitative evidence about work-based learning in health care organisations as experienced by nursing staff. Work-based learning is understood as informal learning that occurs inside the work community in the interaction between employees. Studies for this review were searched for in the CINAHL, PubMed, Scopus and ABI Inform ProQuest databases for the period 2000-2015. Nine original studies met the inclusion criteria. After the critical appraisal by two researchers, all nine studies were selected for the review. The findings of the original studies were aggregated, and four statements were prepared, to be utilised in clinical work and decision-making. The statements concerned the following issues: (1) the culture of the work community; (2) the physical structures, spaces and duties of the work unit; (3) management; and (4) interpersonal relations. Understanding the nurses' experiences of work-based learning and factors behind these experiences provides an opportunity to influence the challenges of learning in the demanding context of health care organisations.

2013-01-01

Based on the author’s own work and results obtained by international teams he coordinated, this SpringerBrief offers a concise discussion of the origin and early evolution of atmospheres of terrestrial planets during the active phase of their host stars, as well as of the environmental conditions which are necessary in order for planets like the Earth to obtain N_2-rich atmospheres. Possible thermal and non-thermal atmospheric escape processes are discussed in a comparative way between the planets in the Solar System and exoplanets. Lastly, a hypothesis for how to test and study the discussed atmosphere evolution theories using future UV transit observations of terrestrial exoplanets within the orbits of dwarf stars is presented.

Contextualising primate origins--an ecomorphological framework.

Science.gov (United States)

Soligo, Christophe; Smaers, Jeroen B

2016-04-01

Ecomorphology - the characterisation of the adaptive relationship between an organism's morphology and its ecological role - has long been central to theories of the origin and early evolution of the primate order. This is exemplified by two of the most influential theories of primate origins: Matt Cartmill's Visual Predation Hypothesis, and Bob Sussman's Angiosperm Co-Evolution Hypothesis. However, the study of primate origins is constrained by the absence of data directly documenting the events under investigation, and has to rely instead on a fragmentary fossil record and the methodological assumptions inherent in phylogenetic comparative analyses of extant species. These constraints introduce particular challenges for inferring the ecomorphology of primate origins, as morphology and environmental context must first be inferred before the relationship between the two can be considered. Fossils can be integrated in comparative analyses and observations of extant model species and laboratory experiments of form-function relationships are critical for the functional interpretation of the morphology of extinct species. Recent developments have led to important advancements, including phylogenetic comparative methods based on more realistic models of evolution, and improved methods for the inference of clade divergence times, as well as an improved fossil record. This contribution will review current perspectives on the origin and early evolution of primates, paying particular attention to their phylogenetic (including cladistic relationships and character evolution) and environmental (including chronology, geography, and physical environments) contextualisation, before attempting an up-to-date ecomorphological synthesis of primate origins. © 2016 Anatomical Society.

Historical Development of Origins Research

Science.gov (United States)

Lazcano, Antonio

2010-01-01

Following the publication of the Origin of Species in 1859, many naturalists adopted the idea that living organisms were the historical outcome of gradual transformation of lifeless matter. These views soon merged with the developments of biochemistry and cell biology and led to proposals in which the origin of protoplasm was equated with the origin of life. The heterotrophic origin of life proposed by Oparin and Haldane in the 1920s was part of this tradition, which Oparin enriched by transforming the discussion of the emergence of the first cells into a workable multidisciplinary research program. On the other hand, the scientific trend toward understanding biological phenomena at the molecular level led authors like Troland, Muller, and others to propose that single molecules or viruses represented primordial living systems. The contrast between these opposing views on the origin of life represents not only contrasting views of the nature of life itself, but also major ideological discussions that reached a surprising intensity in the years following Stanley Miller’s seminal result which showed the ease with which organic compounds of biochemical significance could be synthesized under putative primitive conditions. In fact, during the years following the Miller experiment, attempts to understand the origin of life were strongly influenced by research on DNA replication and protein biosynthesis, and, in socio-political terms, by the atmosphere created by Cold War tensions. The catalytic versatility of RNA molecules clearly merits a critical reappraisal of Muller’s viewpoint. However, the discovery of ribozymes does not imply that autocatalytic nucleic acid molecules ready to be used as primordial genes were floating in the primitive oceans, or that the RNA world emerged completely assembled from simple precursors present in the prebiotic soup. The evidence supporting the presence of a wide range of organic molecules on the primitive Earth, including membrane

Analysis of the relation of copyright and work content in judicial verdicts of USA, UK and Canada

Full Text Available According to copyright system, the normal standard for protecting literary and artistic works is originality hence the international copyright treaties such as Berne convention, while emphasizing on originality are avoiding imposing other mandatory standards for protecting such works. However, these works are different forms of expression of various ideas and accordingly, comprise different contents. In some cases, the works contents are inconsistent with religious and national values and norms or society custom and laws. There are conflicts between protecting copyright as an intellectual property right and other moral, religious and legal priorities in the society. For resolving this conflict and answering the question whether work content will affect copyright protection, countries have adopted different approaches. From the perspective of the work content, this article through a comparative study of approaches and judicial verdicts of the USA, the UK and Canada, infers two general views: the work content does not have any impacts on copyright protection and the work content have impacts on copyright protection. In addition, some supporters of second view believe in content impact on existence of copyright in a work and other supporters believe that content has impacts on some enforcements of copyright.

Ethnic identity and gender as moderators of the association between discrimination and academic adjustment among Mexican-origin adolescents.

Science.gov (United States)

Umaña-Taylor, Adriana J; Wong, Jessie J; Gonzales, Nancy A; Dumka, Larry E

2012-08-01

Existing work has identified perceived discrimination as a risk factor that may contribute to the relatively poorer academic outcomes exhibited by Mexican-origin adolescents in the U.S. The current study examined the longitudinal associations among perceived discrimination and three indices of adolescent adjustment in the school setting (i.e., grade point average, teacher reports of externalizing, adolescents' deviant peer associations) among 178 Mexican-origin adolescents (53% female). Ethnic identity affirmation was examined as a protective factor expected to reduce the negative effects of discrimination on adolescents' adjustment, and gender was examined as a potential moderator of the associations of interest. Findings indicated that the deleterious effects of discrimination on adolescents' adjustment in school were particularly salient for Mexican-origin male adolescents. Importantly, ethnic identity affirmation emerged as a protective factor for Mexican-origin male adolescents by buffering the negative effects of discrimination on their externalizing behaviors in school.

Transdisciplinarity: A Review of Its Origins, Development, and Current Issues

Directory of Open Access Journals (Sweden)

Jay Hillel Bernstein

2015-07-01

Full Text Available Transdisciplinarity originated in a critique of the standard configuration of knowledge in disciplines in the curriculum, including moral and ethical concerns. Pronouncements about it were first voiced between the climax of government-supported science and higher education and the long retrenchment that began in the 1970s. Early work focused on questions of epistemology and the planning of future universities and educational programs. After a lull, transdisciplinarity re-emerged in the 1990s as an urgent issue relating to the solution of new, highly complex, global concerns, beginning with climate change and sustainability and extending into many areas concerning science, technology, social problems and policy, education, and the arts. Transdisciplinarity today is characterized by its focus on “wicked problems” that need creative solutions, its reliance on stakeholder involvement, and engaged, socially responsible science. In simultaneously studying multiple levels of, and angles on, reality, transdisciplinary work provides an intriguing potential to invigorate scholarly and scientific inquiry both in and outside the academy.

General order of the origin of life in the Universe

Kompanichenko, V. N.

covers not only to Earth, but to processes in the vast explored Universe too. The used key notions "free energy" and "entropy" are universal and characterize ability or disability of a natural system to carry out work elsewhere. For instance, outbreak of ash by active volcanoes on Earth and Jupiter's satellite Io is the same kind of work that can be approximately evaluated in terms of the spent free energy. The opposite spontaneous and non-spontaneous processes are universal as well. They are described the transition of a natural system to more or less probable state correspondingly. Cooling of a lava flow on Earth and cooling of the entire Mars planet are similar processes related with the spontaneous process - heat conductivity. All stars, planets and other space bodies in the Universe are composed of about one hundred elements systematized in the Periodic Table. In this context behaviour of chemical systems elsewhere in the explored Universe should comply with the fundamental laws determined on Earth, in particular with the Le Chatelier principle, Onsager theorem and the theory of dissipative structures used in this work. For example, outflow of matter from a star occurs simultaneously with outflow of heat energy (i.e. they are interdependent processes) as it follows of the Onsager theorem. The organic microsystems, which are considered as prebiotic for the early Earth, composed of diverse organic compounds that were detected in the space and meteorites (from simple hydrocarbons up to amino acids). Taking these reasons into account, the distinguished three stages in principle can be considered in the context of a general scenario of the origin of life in the Universe. Some new ways of the experimental research in the origin of life field are suggested. The first of them is laboratory experimental research of diverse prebiotic models at the state of bifurcate transition and under oscillating conditions in the experimental chamber. The goal of the experiments is to

To examine the neurologic cinematographic contributions of Gheorghe Marinescu. Near the end of the 19th century, cinematography developed and was immediately recognized as a new technique applicable to medical documentation. After studying with several prominent European neurologists and deeply influenced by Jean-Martin Charcot, Marinescu returned to Bucharest in 1897 and applied moving picture techniques to the study of neurologic patients. The Romanian State Archives were researched for original Marinescu films, and related publications were translated from Romanian and French. Between 1899 and 1902, Marinescu perfected the use of cinematography as a research method in neurosciences and published five articles based on cinematographic documents. He focused his studies particularly on organic gait disorders, locomotor ataxia, and hysteria. He adapted Charcot's method of lining up several patients with the same disorder and showing them together to permit appreciation of archetypes and formes frustes. He decomposed the moving pictures into sequential tracings for publication. He documented treatment results with cases filmed before and after therapy. Processed and digitized excerpts of these films accompany this manuscript. Marinescu's cinematographic studies led to several original contributions in clinical neurology. Remaining film archives include examples of many neurologic diseases, his examination techniques, and the working medical environment of the young founder of the Romanian school of neurology.

Estimates of impact levels onto environment were made when implementing stabilization works of unstable building structures of Ukryttya object. The impact were evaluated to air water medium, as well to ground cover, social and technogenic environments. It was demonstrated, that impact levels to above environmental components under normal conditions of work implementation are negligible, and radioactive substance amount, which will penetrate into the environment, will make parts of percents to existing contamination of exclusion zone area. Estimates are also made of accident impacts onto environment, whose origination is probable during the stabilization works of Ukryttya object

Schwannoma Originating From the Periphereral Intercostal Nerves

Directory of Open Access Journals (Sweden)

Yunus Aksoy

2017-06-01

Full Text Available Schwannomas are usually solitary, encapsulated, and asymptomatic, benign neurogenic tumors originating from the nerve sheath. Schwannomas rarely show malignant transformation, however, require close monitoring. They are primarily located in the thorax in the costovertebral sulcus, may rarely originate from peripheral intercostal nerves. Less than 10% of primary thoracic neurogenic tumors originate from the peripheral intercostal nerves. The main treatment and diagnosis of schwannomas are complete surgical resection. We report a rare case of a 40-year-old male with asymptomatic schwannoma originating from an intercostal nerve which was found incidentally on his chest X-ray and was treated with surgery.

The Origin and Dynamics of Solar Magnetism

CERN Document Server

Thompson, M. J; Culhane, J. L; Nordlund, Å; Solanki, S. K; Zahn, J.-P

2009-01-01

The articles collected in this volume present all aspects of solar magnetism: from its origin in the solar dynamo to its evolution and dynamics that create the variability of solar phenomena, its well-known 11-year activity cycle that leads to the ever-changing pattern of sunspots and active regions on the Sun. Several contributions deal with the solar dynamo, the driver of many solar phenomena. Other contributions treat the transport and emergence of the magnetic flux through the outer layers of the Sun. The coupling of magnetic fields from the surface to the solar corona and beyond is also described, together with current studies on the predictability of solar activity. This book is aimed at researchers and graduate students working in solar physics and space science. It provides a full review of our current understanding of solar magnetism by the foremost experts in the field.

Creative work. The case of Charles Darwin.

Science.gov (United States)

Gruber, H E; Wallace, D B

2001-04-01

The evolving systems approach (ESA) addresses the need for direct study of the creative process in recognized creators at work, in contrast to indirect methods, such as those used in psychometric studies. The ESA emerged from H. E. Gruber's prolonged study of Charles Darwin's manuscripts, especially the notebooks he kept after the Beagle voyage. Gruber's interviews with J. Piaget about the latter's creative processes, as well as many doctoral dissertations, also helped shape the authors' approach. Using Gruber's (1974/1981) study of Darwin, the authors describe some facets of creative work identified in the course of their work. Among these are networks of enterprise, ensembles of metaphors, insights, and evolving belief systems. Although the ESA emphasizes cognitive processes, social, affective, and esthetic aspects of the case are not neglected. Each creative case is unique, otherwise the individual would not meet the criterion of originality. Uniqueness does not mean isolation; people who differ must and do work together. The integration of all these facets into a plausible system for each creator remains the authors' central task.

Evidence-based medicine and hospital reform: tracing origins back to Florence Nightingale.

Science.gov (United States)

Aravind, Maya; Chung, Kevin C

2010-01-01

The use of reliable evidence to evaluate health care interventions has gained strong support within the medical community and in the field of plastic surgery in particular. Evidence-based medicine aims to improve health care and reduce costs through the use of sound clinical evidence in evaluating treatments, procedures, and outcomes. The field is hardly new, however, and most trace its origins back to the work of Cochrane in the 1970s and Sackett in the 1990s. Though she wouldn't know it, Florence Nightingale was applying the concepts of evidence-based reform to the medical profession more than a century before. She used medical statistics to reveal the nature of infection in hospitals and on the battlefield. Moreover, Nightingale marshaled data and evidence to establish guidelines for health care reform. Tracing the origins of evidence-based medicine back to Nightingale underscores how critical this movement is to improving the quality and effectiveness of patient care today.

Reducing work disability in Ankylosing Spondylitis – development of a work instability scale for AS

Directory of Open Access Journals (Sweden)

Helliwell Philip

2009-06-01

Full Text Available Abstract Background The Work Instability Scale for Rheumatoid Arthritis (RA-WIS is established and is used by physicians to identify patients at risk of job loss for rapid intervention. The study objective was to explore the concept of Work Instability (a mismatch between an individual's abilities and job demands in Ankylosing Spondylitis (AS and develop a Work Instability Scale specific to this population. Methods New items generated from qualitative interviews were combined with items from the RA-WIS to form a draft AS-WIS. Rasch analysis was used to examine the scaling properties of the AS-WIS using data generated through a postal survey. The scale was validated against a gold standard of expert assessment, a test-retest survey examined reliability. Results Fifty-seven participants who were in work returned the postal survey. Of the original 55 items 38 were shown to fit the Rasch model (χ2 37.5; df 38; p 0.494 and free of bias for gender and disease duration. Following analysis for discrimination against the gold standard assessments 20 items remained with good fit to the model (χ2 24.8; df 20; p 0.21. Test-retest reliability was 0.94. Conclusion The AS-WIS is a self-administered scale which meets the stringent requirements of modern measurement. Used as a screening tool it can identify those experiencing a mismatch at work who are at risk of job retention problems and work disability. Work instability is emerging as an important indication for the use of biologics, thus the AS-WIS has the potential to become an important outcome measure.

Initiation preference at a yeast origin of replication.

Science.gov (United States)

Brewer, B J; Fangman, W L

1994-04-12

Replication origins in the yeast Saccharomyces cerevisiae are identified as autonomous replication sequence (ARS) elements. To examine the effect of origin density on replication initiation, we have analyzed the replication of a plasmid that contains two copies of the same origin, ARS1. The activation of origins and the direction that replication forks move through flanking sequences can be physically determined by analyzing replication intermediates on two-dimensional agarose gels. We find that only one of the two identical ARSs on the plasmid initiates replication on any given plasmid molecule; that is, this close spacing of ARSs results in an apparent interference between the potential origins. Moreover, in the particular plasmid that we constructed, one of the two identical copies of ARS1 is used four times more frequently than the other one. These results show that the plasmid context is critical for determining the preferred origin. This origin preference is also exhibited when the tandem copies of ARS1 are introduced into a yeast chromosome. The sequences responsible for establishing the origin preference have been identified by deletion analysis and are found to reside in a portion of the yeast URA3 gene.

1984-01-01

The generally accepted concept has it that the Sun and the planets originated almost simultaneously from nebula (the nebular hypothesis). It is assumed that the temperature of the nebula decreased in the direction from the centre which led to the segregation of elements and to the different chemical composition of the individual planets. The planets formed either from the gravitational collapse of part of the nebula or by gradual accretion. In the scenario of the origin of the solar system there are many blank spots, namely as concerns the initial stages of development and the period when the formation of the planets had ''almost been completed''.

Knowledge, organization, and management building on the work of Max Boisot

CERN Document Server

Ihrig, Martin

2013-01-01

Max Boisot was one of the most original thinkers in management and organization studies. An independent scholar with an independent, enquiring, and innovative mind, his work ranged over a number of different areas from early attempts to understand contemporary developments in China to the role of information in organizations, and later the management of Big Science. Yet, as this book shows, there was a central strand that ran through these apparently diverse areas, which was the attempt to understand the relationship between knowledge and information, and its organization -- in firms, organizations, and societies -- by means of the model Boisot developed, the 'I-Space'. Knowledge, Organization, and Management brings together key examples of Max Boisot's work into a single volume, setting these alongside original, extended commentaries and reflections by his academic collaborators. Structured under five core sections, it covers the main areas in which he forged new understandings: analyses of the Chinese syste...

First steps in eukaryogenesis: Physical phenomena in the origin and evolution of chromosome structure

International Nuclear Information System (INIS)

Chela Flores, J.

1995-01-01

Our present understanding of the origin and evolution of chromosomes differs considerably from current understanding of the origin and evolution of the cell itself. Chromosome origins have been less prominent in research, as the emphasis has not shifted so far appreciably from the phenomenon of primeval nucleic acid encapsulation to that of the origin of gene organization, expression, and regulation. In this work we discuss some reasons why preliminary steps in this direction are being taken. We have been led to examine properties that have contributed to raise the ancestral prokaryotic programmes to a level where we can appreciate in eukaryotes a clear departure from earlier themes in the evolution of the cell from the last common ancestor. We shift our point of view from evolution of cell morphology to the point of view of the genes. In particular, we focus attention on possible physical bases for the way transmission of information has evolved in eukaryotes, namely, the inactivation of whole chromosomes. The special case of inactivation of the X chromosome in mammals is discussed, paying particular attention to the physical process of the spread of X inactivation in monotremes (platypus and echidna.) When experimental data is unavailable some theoretical analysis is possible based on the idea that in certain cases collective phenomena in genetics, rather than chemical detail, are better correlates of complex chemical processes.

Baji, Petra; Gulácsi, László; Lovász, Barbara D; Golovics, Petra A; Brodszky, Valentin; Péntek, Márta; Rencz, Fanni; Lakatos, Péter L

2016-01-01

To explore preferences of gastroenterologists for biosimilar drugs in Crohn's disease. Discrete choice experiment was carried out involving 51 Hungarian gastroenterologists in May 2014. The following attributes were used to describe hypothetical choice sets: 1) type of the treatment (biosimilar/originator), 2) severity of disease, 3) availability of continuous medicine supply, 4) frequency of the efficacy check-ups. Multinomial logit model was used to differentiate between three attitude types: 1) always opting for the originator, 2) willing to consider biosimilar for biological-naïve patients only, 3) willing to consider biosimilar treatment for both types of patients. Conditional logit model was used to estimate the probabilities of choosing a given profile. Men, senior consultants, working in inflammatory bowel disease center and treating more patients were more likely willing to consider biosimilar for biological-naïve patients only. Treatment type (originator/biosimilar) was the most important determinant of choice for patients already treated with biologicals, and the availability of continuous medicine supply in case of biological-naïve patients. The probabilities of choosing the biosimilar with all the benefits offered over the originator under current reimbursement conditions are 89% versus 11% for new patients, and 44% versus 56% for patients already treated with biological. For gastroenterologist, the continuous medical supply would be one of the major benefits of biosimilars. However, benefits offered in the scenarios do not compensate for the change from the originator to the biosimilar treatment of patients already treated with biologicals.

Origin and dispersion of the Tupiguarani: what does cranial morphology say?

Directory of Open Access Journals (Sweden)

Walter Alves Neves

2011-04-01

Full Text Available The origin and dispersion of the Tupiguarani groups have been intensely debated among archaeologists and linguists in the last five decades. In summary it is widely accepted by archeologists that the ethnogenesis of this linguistic stock, who occupied the majority of Brazilian territory and part of Bolivia, Paraguay, Uruguay and Argentina, can be traced to Amazonia and from there migrated eastward and southward around 2,500 years before present, although a dispersion in the opposite direction, i.e., from south to north, with an origin in the basin of the Tietê-Paraná region, has not been completely ruled out. Among the archaeologists who regard Amazonia as the birthplace of these people, some believe that they originated in Central Amazonia. Others believe that the Tupiguarani's ethnogenesis occurred in southwestern Amazonia, where the majority of Tupi linguistic diversity is currently concentrated. In this study, the morphology of 19 human skulls associated with the Tupiguarani archaeological tradition, or ethnographically described as such, were compared with several prehistoric and ethnographic cranial series from Brazil by means of multivariate statistics. Two multivariate techniques were used: Principal Components Analysis applied to the centroid of each series and the Mahalanobis Distance applied to the individual data. Our results suggest an Amazonian connection for the Tupiguarani people, mainly because of the strong association found between Tupi and Guarani skulls from southern and southeastern Brazil and Tupi from northern Brazil with specimens from Marajó Island included in the work.

Quest for the dynamical origin of mass. An LHC perspective from Sakata, Nambu and Maskawa

International Nuclear Information System (INIS)

Yamawaki, Koichi

2009-01-01

I review the dynamical symmetry breaking (DSB) approach to the Origin of Mass, which is traced back to the original (2008 Nobel Prize) work of Nambu based on the BCS analogue of superconductor where mass of nucleon (then elementary particle) arises due to Cooper paring and pions are provided as massless Nambu-Goldstone (NG) bosons, being composite as in Fermi-Yang/Sakata model. In this talk I will focus on the modern version of DSB or composite Higgs models: Walking/Conformal Technicolor, Hidden Local Symmetry (HLS) or Moose, and Top Quark Condensate, with the their extra dimension versions closely related with HLS. Particular emphasis will be placed on the large anomalous dimension and conformal symmetry at the conformal fixed points, developed along the line of the pioneering work of Maskawa and Nakajima. Due to (approximate) conformal symmetry these models do have composite Higgs particle ('Techni-dilaton', 'Top-sigma', etc.). Weakly coupled composite gauge boson is realized at 'Vector Manifestation' formulated at conformal fixed point, which may be applied to the composite W/Z boson models. They will be tested in the upcoming LHC experiments. (author)

We introduce an extension of the Standard Model and General Relativity built upon the principle of local conformal invariance, which represents a generalization of a previous work by Bars, Steinhardt and Turok. This is naturally realized by adopting as a geometric framework a particular class of non-Riemannian geometries, first studied by Weyl. The gravitational sector is enriched by a scalar and a vector field. The latter has a geometric origin and represents the novel feature of our approach. We argue that physical scales could emerge from a theory with no dimensionful parameters, as a result of the spontaneous breakdown of conformal and electroweak symmetries. We study the dynamics of matter fields in this modified gravity theory and show that test particles follow geodesics of the Levi-Civita connection, thus resolving an old criticism raised by Einstein against Weyl's original proposal.

Origins of replication present a paradox to evolutionary biologists. As a collection, they are absolutely essential genomic features, but individually are highly redundant and nonessential. It is therefore difficult to predict to what extent and in what regard origins are conserved over evolutionary time. Here, through a comparative genomic analysis of replication origins and chromosomal replication patterns in the budding yeasts Saccharomyces cerevisiae and Lachancea waltii, we assess to what extent replication origins survived genomic change produced from 150 million years of evolution. We find that L. waltii origins exhibit a core consensus sequence and nucleosome occupancy pattern highly similar to those of S. cerevisiae origins. We further observe that the overall progression of chromosomal replication is similar between L. waltii and S. cerevisiae. Nevertheless, few origins show evidence of being conserved in location between the two species. Among the conserved origins are those surrounding centromeres and adjacent to histone genes, suggesting that proximity to an origin may be important for their regulation. We conclude that, over evolutionary time, origins maintain sequence, structure, and regulation, but are continually being created and destroyed, with the result that their locations are generally not conserved.

This work pinpointed the goatgrass chromosomal segment in the wheat B genome using modern cytogenetic and genomic technologies, and provided novel insights into the origin of the wheat B genome. Wheat is a typical allopolyploid with three homoeologous subgenomes (A, B, and D). The donors of the subgenomes A and D had been identified, but not for the subgenome B. The goatgrass Aegilops speltoides (genome SS) has been controversially considered a possible candidate for the donor of the wheat B genome. However, the relationship of the Ae. speltoides S genome with the wheat B genome remains largely obscure. The present study assessed the homology of the B and S genomes using an integrative cytogenetic and genomic approach, and revealed the contribution of Ae. speltoides to the origin of the wheat B genome. We discovered noticeable homology between wheat chromosome 1B and Ae. speltoides chromosome 1S, but not between other chromosomes in the B and S genomes. An Ae. speltoides-originated segment spanning a genomic region of approximately 10.46 Mb was detected on the long arm of wheat chromosome 1B (1BL). The Ae. speltoides-originated segment on 1BL was found to co-evolve with the rest of the B genome. Evidently, Ae. speltoides had been involved in the origin of the wheat B genome, but should not be considered an exclusive donor of this genome. The wheat B genome might have a polyphyletic origin with multiple ancestors involved, including Ae. speltoides. These novel findings will facilitate genome studies in wheat and other polyploids.

Full Text Available Work engagement is defined as a positive, affective-motivational state of work-related well-being characterized by vigor, dedication and absorption. The Utrecht Work Engagement Scale (UWES is the most frequently used measure of work engagement. The aim of this study was to analyze the psychometric properties of the Serbian versions of the UWES-17 and UWES-9. The sample consisted of 860 employees from a number of organizations and jobs across Serbia. Based on the UWES-17 findings, the data confirm both the three-factor and one-factor solutions by giving a slight advantage to the three-factor solution. As for the UWES-9, based on the PCFA and CFA, the one-factor solution was obtained as the preferred one. Taking into account the UWES-9 reliability and correlation patterns of its subscales with other well-being variables, both one- and three-factor solutions of the UWES-9 are suggested for future research. Serbian versions of both the UWES-17 and UWES-9 have satisfactory psychometric properties with high reliability, factorial structure in line with the theoretical model, and good predictive validity. The study contributes to enhanced understanding of work engagement by offering an insight from the Serbian cultural and economic context, significantly different from the UWES originating setting. There is still a need for exploring how employees from Serbia conceptualize work engagement, as well as for further, more stringent investigating of the cultural invariance of the UWES factorial structure.

A Review of Ideas Concerning Life Origin

Science.gov (United States)

Gindilis, L. M.

2014-10-01

Since the times of Antiquity the and for a long time the idea of self-origination of life was the dominant one. It reappeared again after microorganisms were discovered (XVII century). The possibility of abiogenesis at microbial level was discussed for more than a century. Pateur demonstrated that spontaneous origination of microorganisms in sterile broth was due to those same microorganisms transported by dust particles. Thus proving that every form of life originates from the parental life form. So the question arises: how did the first microorganisms appear on the Earth. There are three possible versions: 1) accidental origination of a viable form; 2) primal organisms were transported to the Earth from outer space; 3) they were formed on the Earth in the process of prebiotic chemical evolution. We discuss the problems of prebiotic evolution from simple monomers up to living cells. An important item of nowadays conceptions of life origination is the hypothesis of the ancient world of RNA as possible precursor of life on Earth. The discovery in carbonaceous chondrites of traces of bacterial life evidences the existence of life in the Solar System even before the formation of the Earth. The idea of life as brought to the Earth out of Cosmos originated under the impression of self-origination hypothesis downfall. It went through several stages (Helmholtz, W. Thompson, XIX century; Arrhenius, early XX century; Hoyle and Wickramasinghe, second half of XX century) and presently evokes constantly growing interest. The panspermia theory does not solve the problem of origination of life, only moves it onto other planets. According to V.A. Mazur, the probability of accidental formation of RNA molecule is negligible not only on the Earth, but in the whole Universe over all the time span of its existence. But it is practically equal to unit in the domain formed at the inflation stage of the evolution of the Universe. A.D.Panov considered panspermia in the Galaxy at the level

CERN. Geneva

1981-01-01

Many labs try to boost existing data acquisition systems by inserting high performance intelligent devices in the important nodes of the system's structure. This strategy finds its limits in the system's architecture. The CHADAC project proposes a simple and efficient solution to this problem, using a multiprocessor modular architecture. CHADAC main features are: parallel acquisition of data; CHADAC is fast, it dedicates one processor per branch and each processor can read and store one 16 bit word in 800 ns; original structure; each processor can work in its own private memory, in its own shared memory (double access) and in the shared memory of any other processor. Simple and fast communications between processors are also provided by local DMAs; flexibility; each processor is autonomous and may be used as an independent acquisition system for a branch, by connecting local peripherals to it. Adjunction of fast trigger logic is possible. By its architecture and performances, CHADAC is designed to provide a g...

Investigations of the origin of cosmic rays are presented. Different methods are discussed: studies of cosmic gamma rays of energy from 30 MeV to about 10{sup 15} eV (since photons point to their places of origin), studies of the mass composition of cosmic rays (because it reflects source morphology), and studies of cosmic rays with energy above 1O{sup 19} eV (for these are the highest energies observed in nature).

On the origins of hierarchy in complex networks

Science.gov (United States)

Corominas-Murtra, Bernat; Goñi, Joaquín; Solé, Ricard V.; Rodríguez-Caso, Carlos

2013-01-01

Hierarchy seems to pervade complexity in both living and artificial systems. Despite its relevance, no general theory that captures all features of hierarchy and its origins has been proposed yet. Here we present a formal approach resulting from the convergence of theoretical morphology and network theory that allows constructing a 3D morphospace of hierarchies and hence comparing the hierarchical organization of ecological, cellular, technological, and social networks. Embedded within large voids in the morphospace of all possible hierarchies, four major groups are identified. Two of them match the expected from random networks with similar connectivity, thus suggesting that nonadaptive factors are at work. Ecological and gene networks define the other two, indicating that their topological order is the result of functional constraints. These results are consistent with an exploration of the morphospace, using in silico evolved networks. PMID:23898177

CIVIL ENGINEERS' ROLES IN PUBLIC WORKS

Science.gov (United States)

Murata, Teruaki

Recently, the public interests are becoming high in the way of executing public works and the future direction of infrastructure development, which raises nation-wide discussion on these issues. How should we make our country's growth strategy for sustainable development? How should we realize the grand design of infrastructure needed for the implementation of such a strategy? It is obvious that further discussions are needed for these challenging questions. With an aim to promote such discussions, this paper reviews the history of public works and the professional practices (or accomplishments) of our great civil engineers, and discusses the future of public works and the roles of civil engineers based on their origin. Further, in this paper, the author, as the chairman of the Public Works Committee of Japan Civil Engineering Contractors Association, introduces the Association's proposal of "realization of an attractive construction industry." However, for its realization, sustainable institutional arrangements under social consensus are indispensable. Also, individual engineer must establish his/her own identity based on sense of social ethics. It is the author's hope that, through these journals, the professional practices of civil engineers will be widely known to the public with objective logics and discussed to achieve social consensus.

Rutherford, Radioactivity and the Origins of Nuclear Physics

International Nuclear Information System (INIS)

Hughes, J

2012-01-01

When Ernest Rutherford became Professor of Physics at Manchester University in 1907, he brought with him the research field in which he had played a leading role over the previous few years: radioactivity. Rutherford turned the Manchester physics lab over to studies of radioactivity and radiation, and through his own work and that of his many collaborators and students, established Manchester as a major international centre in atomic physics. It was out of this powerhouse that the nuclear theory of the atom emerged in 1911. In 1917, Rutherford 'disintegrated' the nitrogen nucleus using α-particles, opening up the possibility of nuclear structure. At Cambridge's Cavendish Laboratory from 1919, Rutherford and his co-workers began to explore the constitution of the nucleus. With Chadwick, Aston and others, Rutherford turned his research school to the emergent field of nuclear physics – a field he dominated (though not without controversy) until his death in 1937. Exploring the intellectual, material and institutional cultures of early twentieth century physics, this paper will outline the background to Rutherford's career and work, the experimental and theoretical origins of nuclear theory of the atom and the early development of nuclear physics.

Rao, Relangi Tulasi; Jayakumar, Kannan; Kumar, Pavitra

2017-10-01

The study aimed to assess the nature of animal origin Staphylococcus aureus strains. The study has zoonotic importance and aimed to compare virulence between two different hosts, i.e., bovine and ovine origin. Conventional polymerase chain reaction-based methods used for the characterization of S. aureus strains and chick embryo model employed for the assessment of virulence capacity of strains. All statistical tests carried on R program, version 3.0.4. After initial screening and molecular characterization of the prevalence of S. aureus found to be 42.62% in bovine origin samples and 28.35% among ovine origin samples. Meanwhile, the methicillin-resistant S. aureus prevalence is found to be meager in both the hosts. Among the samples, only 6.8% isolates tested positive for methicillin resistance. The biofilm formation quantified and the variation compared among the host. A Welch two-sample t -test found to be statistically significant, t=2.3179, df=28.103, and p=0.02795. Chicken embryo model found effective to test the pathogenicity of the strains. The study helped to conclude healthy bovines can act as S. aureus reservoirs. Bovine origin S. aureus strains are more virulent than ovine origin strains. Bovine origin strains have high probability to become zoonotic pathogen. Further, gene knock out studies may be conducted to conclude zoonocity of the bovine origin strains.

A systematic review of prognostic factors for return to work following work-related traumatic hand injury.

2014-01-01

Systematic review. Traumatic hand injuries are frequent cause of work related injuries and can result in prolonged durations of time loss from work. To systematically review available evidence to determine which prognostic factors predict return-to-work (RTW) following work-related traumatic hand injuries. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO from 1980 to September 2013 and reference lists of articles. Studies investigating any prognostic factors of RTW after traumatic hand injury were included. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Identified factors were grouped into conceptual prognostic factor categories. We assessed 8 studies, which addressed 11 potential prognostic factors (i.e., sociodemographic factors, occupation, work compensation status, treatment related factors, impairment severity, location of injury, etc.). The quality of the studies was low to moderate. Across all included studies, RTW (original or modified work) occurred in over 60% of individuals by 6 months. There was consistent low-moderate quality evidence that individuals with more severe impairments and lower pre-injury income were less likely to RTW, and low-moderate quality evidence that age, gender and level of education had no impact on RTW. Evidence on other commonly cited prognostic factors were limited in the literature. Impairment severity and lower pre-injury income showed a consistent association with RTW following occupational hand injury, while other factors demonstrated no or variable effects across studies. Additional high-quality studies are warranted toward improving our understanding of the complex factors that mediate RTW following a traumatic work-related hand injury. 2a.

Professor Rafael Molla Rodrigo is considered by some the author who contributed with his scientific work and solid technique to consolidate Urology as a speciality in Valencia. Such importance is also perceived in a national level, as demonstrated by the fact that he belonged to the first board of the Spanish Association of Urology and contributed to its foundation in the two-year period 1910--1911, from his position of head of the department of Surgical Therapy and Operations at the Central University. Genitourinary tuberculosis is one of the most outstanding chapters of his extensive works. We reviewed all his works, selecting all original articles about genitourinary tuberculosis. Original articles have been obtained from the journals Revista de Higiene y Tuberculosis, La Medicina Valenciana, Revista Valenciana de Ciencias Médicas y Policínica, and from his two most important books, Clinical Lessons In Urology and Clinical Lessons in Urology and Genitourinary Surgery. Throughout his work he analyzes features of relevance about this disease, such as diagnosis, about which he emphasizes the clinical and bacteriological difficulties, and treatment, which was only feasible by precocious nephrectomy. He dedicates a great part of his work to the study of this pathology and defends a precocious diagnosis in order to perform the only treatment that had demonstrated efficacy. He also exposes the symptoms and variety of clinical presentations, as well as diagnosis through separate kidney catheterization with the aim to determine unilateral involvement.

Dynamics of comets: their origin and evolution

International Nuclear Information System (INIS)

Carusi, A.; Valsecchi, G.B.

1985-01-01

Comets can be considered as remnants of the original population of planetesimals and the study of their origin and dynamical histories can provide insight into the accretion phenomena; the original mass, energy and angular momentum distribution across the solar system; the collisional fragmentation of minor bodies; the impact rates on planets and the nature of impacting bodies. The interaction of comets with other solar system bodies certainly provides one of the best possibilities for a deeper understanding of the dynamics of the whole system, and a challenging test for all theories of celestial mechanics dealing with the gravitational behaviour of multiple-body systems. Comets could also be considered as the last footprints left by the interaction of the protosun and its original galactic environment. (orig.)

Recognition in ants: social origin matters.

Directory of Open Access Journals (Sweden)

Joël Meunier

Full Text Available The ability of group members to discriminate against foreigners is a keystone in the evolution of sociality. In social insects, colony social structure (number of queens is generally thought to influence abilities of resident workers to discriminate between nestmates and non-nestmates. However, whether social origin of introduced individuals has an effect on their acceptance in conspecific colonies remains poorly explored. Using egg-acceptance bioassays, we tested the influence of social origin of queen-laid eggs on their acceptance by foreign workers in the ant Formica selysi. We showed that workers from both single- and multiple-queen colonies discriminated against foreign eggs from single-queen colonies, whereas they surprisingly accepted foreign eggs from multiple-queen colonies. Chemical analyses then demonstrated that social origins of eggs and workers could be discriminated on the basis of their chemical profiles, a signal generally involved in nestmate discrimination. These findings provide the first evidence in social insects that social origins of eggs interfere with nestmate discrimination and are encoded by chemical signatures.

Origin and diversification of TRIM ubiquitin ligases.

Directory of Open Access Journals (Sweden)

Ignacio Marín

Full Text Available Most proteins of the TRIM family (also known as RBCC family are ubiquitin ligases that share a peculiar protein structure, characterized by including an N-terminal RING finger domain closely followed by one or two B-boxes. Additional protein domains found at their C termini have been used to classify TRIM proteins into classes. TRIMs are involved in multiple cellular processes and many of them are essential components of the innate immunity system of animal species. In humans, it has been shown that mutations in several TRIM-encoding genes lead to diverse genetic diseases and contribute to several types of cancer. They had been hitherto detected only in animals. In this work, by comprehensively analyzing the available diversity of TRIM and TRIM-like protein sequences and evaluating their evolutionary patterns, an improved classification of the TRIM family is obtained. Members of one of the TRIM subfamilies defined, called Subfamily A, turn to be present not only in animals, but also in many other eukaryotes, such as fungi, apusozoans, alveolates, excavates and plants. The rest of subfamilies are animal-specific and several of them originated only recently. Subfamily A proteins are characterized by containing a MATH domain, suggesting a potential evolutionary connection between TRIM proteins and a different type of ubiquitin ligases, known as TRAFs, which contain quite similar MATH domains. These results indicate that the TRIM family emerged much earlier than so far thought and contribute to our understanding of its origin and diversification. The structural and evolutionary links with the TRAF family of ubiquitin ligases can be experimentally explored to determine whether functional connections also exist.

Work-Related Attitudes of Czech Generation Z: International Comparison

Directory of Open Access Journals (Sweden)

Jaroslava Kubátová,

2016-12-01

Full Text Available The goal of this article is to present work-related attitudes of a sample of Czech Generation Z and their comparison to the results of an international research study. Currently, there are three important trends influencing the labor market: (1 the origin and development of a ubiquitous working environment, (2 the thriving of coworking centers, and (3 Generation Z's entering the labor market. Instead of traditional jobs, the bearers of human capital tend to choose independent work in an online environment, and often work in coworking centers. Using self-determination theory, we substantiate why they thrive better this way. Based on the results of an international research project focused on work attitudes among Generation Z and the results of a replication study we carried out in the Czech Republic, we attest that members of Generation Z may prefer independent virtual work in coworking centers, too. The total amount of available human capital, the lack of which is pointed out by companies, may grow thanks to new ways of working. Companies, which can use human capital of independent workers, gain a competitive advantage.

Monographs in Aerospace History Series No. 11. Together in Orbit: The Origins of International Participation in the Space Station

Science.gov (United States)

Logsdon, John M.

1998-01-01

This essay is a history and analysis of the steps leading to the origins of the space station partnership between the United States and its closest allies. It traces the process that led to the decision to invite other countries to participate in the project and their reasons for accepting that invitation. Not covered in this account are the difficult negotiations during the 1984-1988 period that led first to an initial set of agreements that allowed the prospective partners to work together during the early stages of the space station program and then to the final set of agreements creating the original space station partnership. Also, the 1993 invitation to the Russian Federation to join the original partners is not discussed, nor are the subsequent negotiations to revise the 1988 agreements.

Chemical composition of the thermomineral waters of Josanicka Banja spa as an origin indicator, balneological valorization and geothermal potential

Directory of Open Access Journals (Sweden)

Milenić Dejan R.

2015-01-01

Full Text Available The chemical composition of the groundwater is directly dependent on the geological structure, hydrogeological and hydrochemical characteristics and as such it represents an output result of all the factors and processes which take place in the environment within which they were formed. The chemical composition of thermomineral waters often represents a crucial factor in determining the origin, balneological valorization and geothermal potential of the resources. This work presents the analysis of origin, belneological valorization and geothermal potential of Josanicka Banja spa, on the basis of the results gained through making the analyisis of chemical contents of the thermomineral waters which occur in the area. The ratio of concentrations of specific chemical components in the thermomineral waters of Josanicka Banja has served as the basic tool for ascertaining the origin of these waters. On the basis of the analysis of the main anion-cation and gas compositions as well as the contents of specific micro-components, a balneological valorization of these resources has been carried out. Apart from that this work also presents the calculation of the expected temperatures in the primary geothermal reservoir, which was carried out on the basis of the results of chemical analysis of thermomineral waters that occur in the area. Geothermal potential of about 4 MWt and significant contents of balneologically active components of the chemical composition of these waters, open up a possibility for their multi-purpose use, which is also presented in the work.

Origin of the cosmic x-ray background

International Nuclear Information System (INIS)

Margon, B.

1983-01-01

Since 1962, it has been known that every part of the sky emits a uniform glow of x-rays. After two decades of intense study the origin of this diffuse x-ray background is still a subject of controversy. The near perfect isotropy of the x-ray background is clearly a vital clue to its origin. A second clue to the origin of the x-ray background arises from the fact that it is x-radiation tha is generated, rather than some longer wavelength radiation. Two hypotheses of the origin of this x-ray background are discussed. One hypothesis is that the x-ray background can be attributed to bremsstrahlung from a hot intergalactic medium. The second hypothesis is that the x-ray background originates from a large number of quasars. Because there is no estimate independent of the intensity of the x-ray background of how much hot intergalactic medium exists (if any), there is a real possibility that both sources contribute to the observed x-rays.

Particularities of Expropriation Works for Highways and Regional Planning in Romania

Science.gov (United States)

Moscovici, Anca-Maria; Constantin Musat, Cosmin

2017-10-01

In the actual context of modernization and development of the road and railway infrastructure of Romania, we have to make some expropriation works. These works can assure the legal basis on which a said patch will be transferred from a private owner to the ownership of the Romanian state in order to be used for public interest, while the original owner would receive compensation for the patch of land. In this paper we wish to address the particularities of expropriation for highways and regional planning that provide the legal basis by which an estate passes from private property to state ownership in the public interest needs, none the less compensation being paid. In 2006-2007 began the first works of expropriation of land, on the Arad-Timisoara motorway section, under Government Decision no. 1546/2006. The motorway section we will bring up for discussion in 2016 is situated in the administrative-territorial division Galda de Jos, Alba Iulia County. For patches affected by the highway corridor, if it is to expropriate part of the patch, the cadastral documentation has to be established individually for each resulting lot, respectively for the lot/lots that remain in the ownership of the original owner, but also for the expropriated lot.

Work Engagement among Rescue Workers: Psychometric Properties of the Portuguese UWES.

Science.gov (United States)

Sinval, Jorge; Marques-Pinto, Alexandra; Queirós, Cristina; Marôco, João

2017-01-01

Rescue workers have a stressful and risky occupation where being engaged is crucial to face physical and emotional risks in order to help other persons. This study aims to estimate work engagement levels of rescue workers (namely comparing nurses, firefighters, and police officers) and to assess the validity evidence related to the internal structure of the Portuguese versions of the UWES-17 and UWES-9, namely, dimensionality, measurement invariance between occupational groups, and reliability of the scores. To evaluate the dimensionality, we compared the fit of the three-factor model with the fit of a second-order model. A Portuguese version of the instrument was applied to a convenience sample of 3,887 rescue workers (50% nurses, 39% firefighters, and 11% police officers). Work engagement levels were moderate to high, with firefighters being the highest and nurses being the lowest engaged. Psychometric properties were evaluated in the three-factor original structure revealing acceptable fit to the data in the UWES-17, although the UWES-9 had better psychometric properties. Given the observed statistically significant correlations between the three original factors, we proposed a 2 nd hierarchal structure that we named work engagement. The UWES-9 first-order model obtained full uniqueness measurement invariance, and the second-order model obtained partial (metric) second-order invariance.

Original Thinking

Directory of Open Access Journals (Sweden)

Ashok Natarajan

2012-04-01

Full Text Available History that comes to us as a chronology of events is really a collective existence that is evolving through several stages to develop Individuality in all members of the society. The human community, nation states, linguistic groups, local castes and classes, and families are the intermediate stages in development of the Individual. The social process moves through phases of survival, growth, development and evolution. In the process it organizes the consciousness of its members at successive levels from social external manners, formed behavior, value-based character and personality to culminate in the development of Individuality. Through this process, society evolves from physicality to Mentality. The power of accomplishment in society and its members develops progressively through stages of skill, capacity, talent, and ability. Original thinking is made possible by the prior development of thinking that organizes facts into information. The immediate result of the last world war was a shift in reliance from physical force and action to mental conception and mental activity on a global scale. At such times no problem need defy solution, if only humanity recognizes the occasion for thinking and Original Thinking. The apparently insoluble problems we confront are an opportunity to formulate a comprehensive theory of social evolution. The immediate possibility is to devise complete solutions to all existing problems, if only we use the right method of thought development.

`Sex' - It's not only Women's Work: A Case for Refocusing on the Functional Role that Sex Plays in Work for both Women and Men.

Science.gov (United States)

Uretsky, Elanah

2015-01-01

Mention of the term sex work often invokes images of marginalized women at risk for HIV infection. Such images, however, are counterintuitive to the functional role intended by the movement that spawned use of the terms `sex work' and `sex worker'. This article looks at the sexual practices of men in urban China to argue for a return to a functional definition of `sex work', which was originally meant to legitimize the role sex plays in work. The progenitors of this movement intended to use `sex work' as a means to legitimize sex as an income generating activity for women involved in prostitution. I show that sex can also serve a functional role in the work-related duties of men seeking economic and political success in contemporary urban China. Men in China utilize sex as one way for demonstrating the loyalty necessary to access state-owned and controlled resources in a market economy governed under a Leninist system. Overall the article demonstrates that reclaiming perception of sex work as a functional rather than behavioral category can expand its use for preventing HIV among the broad subset of people who engage in sex as part of their work.

The Panchasiddhhantika : The Astronomical Work of Varaha Mihira

Thibaut, G.; Dvivedi, Mahamahopadhyaya Sudhakara

The lamentable state of the text as appearing in the two original manuscripts (of Varah Mihira) at the disposal of the authors, was a lesser problem then the greater disadvantage under which they laboured with the absence of a commentary. Commentaries can be hardly done without in the case of any Sanskrit astronomical work; much less so, when the text, as that of the Panchasiddhantika, describes many mathematical processes more or less diverging from those commonly employed.

Assessing the geographic origin of the invasive grey squirrel using DNA sequencing: Implications for management strategies

Directory of Open Access Journals (Sweden)

Claire D. Stevenson-Holt

2015-01-01

Full Text Available The invasive grey squirrel Sciurus carolinensis has become a major pest species causing negative effects to forestry and biodiversity. This study aims to assess the origin of grey squirrel within Cumbria using phylogeographic analysis to aid in management and control. The work reported analysed mitochondrial DNA sequences in the D-Loop gene of 73 grey squirrel individuals from multiple locations in the UK. The results indicate that individuals in north Cumbria are derived from individuals from Scotland and North East England. Other individuals in north Cumbria share a unique haplotype with south Cumbria and Lancashire suggesting a southerly origin and movement around or over the Cumbrian Mountain range which is thought of as a barrier to movements. The assessment of invasive species geographical origin and the identification of potential wildlife transit corridors through natural barriers are becoming more important as species shift range in response to environmental and ecological changes. With the grey squirrel population expansion also occurring in Italy, the European red squirrel may become threatened across its entire range. It is crucial to understand the population origins of the invasive grey squirrel and landscape usage to successfully manage the incursion routes and control the population.

Shift work and chronic disease: the epidemiological evidence

Science.gov (United States)

Armstrong, M. E. G.; Cairns, B. J.; Key, T. J.; Travis, R. C.

2011-01-01

Background Shift work, including night work, has been hypothesized to increase the risk of chronic diseases, including cancer, cardiovascular disease (CVD), metabolic syndrome and diabetes. Recent reviews of evidence relating to these hypotheses have focussed on specific diseases or potential mechanisms, but no general summary of the current data on shift work and chronic disease has been published. Methods Systematic and critical reviews and recent original studies indexed in PubMed prior to 31 December 2009 were retrieved, aided by manual searches of reference lists. The main conclusions from reviews and principle results from recent studies are presented in text and tables. Results Published evidence is suggestive but not conclusive for an adverse association between night work and breast cancer but limited and inconsistent for cancers at other sites and all cancers combined. Findings on shift work, in relation to risks of CVD, metabolic syndrome and diabetes are also suggestive but not conclusive for an adverse relationship. Conclusions Heterogeneity of study exposures and outcomes and emphasis on positive but non-significant results make it difficult to draw general conclusions. Further data are needed for additional disease endpoints and study populations. PMID:21355031

The Influence of the Country of Origin Image on Brand Equity: A Study of Spanish Banks

Directory of Open Access Journals (Sweden)

Michel Alves Prado

2015-09-01

Full Text Available As there are few studies on the influence of the country of origin image on brand equity for services companies (as it is the case of financial institutions, the aim of this paper is to analyze the influence of the country of origin image on the brand equity of Spanish banks. A descriptive and quantitative research was employed, using the survey method to verify the hypothesis that the country of origin image (Spain positively influences the brand equity of Spanish banks. The main statistical analyzes were the  factor analysis and the multiple regression analysis. As a result, it was found that the Attitude dimension underlying the variable Brand equity of Spanish banks suffered more influence than the Awareness dimension. Furthermore, it was found that the country of origin image positively influences the brand equity of Spanish banks. The technical aspects, in general, influence more than friendly aspects, thus implying a direction for the Spain brand development strategy focused on these aspects. Limitations of this study include the use of a non-probability sample and the use of Spanish banks as the object of study. We suggest the development of new works in the services area, in different categories and with different countries of origin, in order to provide further discussion and theoretical basis for future studies and strategic actions, aiming to create and improve the image of countries.

Genome rearrangements are mediators of evolution and disease. Such rearrangements are frequently bounded by transfer RNAs (tRNAs), transposable elements, and other repeated elements, suggesting a functional role for these elements in creating or repairing breakpoints. Though not well explored, there is evidence that origins of replication also colocalize with breakpoints. To investigate a potential correlation between breakpoints and origins, we analyzed evolutionary breakpoints defined between Saccharomyces cerevisiae and Kluyveromyces waltii and S. cerevisiae and a hypothetical ancestor of both yeasts, as well as breakpoints reported in the experimental literature. We find that origins correlate strongly with both evolutionary breakpoints and those described in the literature. Specifically, we find that origins firing earlier in S phase are more strongly correlated with breakpoints than are later-firing origins. Despite origins being located in genomic regions also bearing tRNAs and Ty elements, the correlation we observe between origins and breakpoints appears to be independent of these genomic features. This study lays the groundwork for understanding the mechanisms by which origins of replication may impact genome architecture and disease.

Structural properties of replication origins in yeast DNA sequences

2008-01-01

Sequence-dependent DNA flexibility is an important structural property originating from the DNA 3D structure. In this paper, we investigate the DNA flexibility of the budding yeast (S. Cerevisiae) replication origins on a genome-wide scale using flexibility parameters from two different models, the trinucleotide and the tetranucleotide models. Based on analyzing average flexibility profiles of 270 replication origins, we find that yeast replication origins are significantly rigid compared with their surrounding genomic regions. To further understand the highly distinctive property of replication origins, we compare the flexibility patterns between yeast replication origins and promoters, and find that they both contain significantly rigid DNAs. Our results suggest that DNA flexibility is an important factor that helps proteins recognize and bind the target sites in order to initiate DNA replication. Inspired by the role of the rigid region in promoters, we speculate that the rigid replication origins may facilitate binding of proteins, including the origin recognition complex (ORC), Cdc6, Cdt1 and the MCM2-7 complex

The work is dedicated to the determination of the origin of archaeological finds from medieval glass using the method of neutron activation analysis (NAA). Among such objects we can discover things not only produced in ancient Russian glassmaking workshops but also imported from Byzantium. The authors substantiate the ancient Russian origin of the medieval glass bracelets of pre-Mongol period, found on the ancient Dubna settlement. The conclusions are based on data on the glass chemical composition obtained as a result of NAA of 10 fragments of bracelets at the IBR-2 reactor, FLNP, JINR.

Among the main sites of production of ancient Chinese blue and white porcelains can be included Jingdezhen in Jiangxi Province, the Yuxi and Jianshui Kilns of Yunnan Province and the Pinghe Kiln of Fujian Province. The current work focuses on an elemental characterization of ancient porcelains according to the location of manufacture, also incorporating a similar study of the blue and white porcelains of the Qing dynasty from Wun Yiu in Hong Kong, and modern blue and white porcelains from Germany, Japan and Thailand. Non-destructive analysis of samples of porcelain using energy dispersive X-ray fluorescence (EDXRF) has yielded results in terms of 13 chemical elements, namely, Ti, Mn, Fe, Co, Ni, Cu, Zn, Ga, Pb, Rb, Sr, Y and Zr. Principal component analysis has been performed on the data, allowing representation of the first, second and third principal components of the data in 3 D scatter plots; the results reveal data clusterings which correlate to a high degree with the known sites of origin. The conclusion is that the present method is capable of determining differences in elemental concentrations of blue and white porcelains, and that these differences can be used to locate the originating site of manufacture.

Family-school relationship and school success: comparison between families of cape-verdian origin, indian origin and natives

Directory of Open Access Journals (Sweden)

Teresa Seabra

2017-06-01

Full Text Available The explanation for the inequality of school performances given by education professionals is often associated with the amplitude of the family support to the offspring’s education. In order to explore this relationship we analyze the results of part of a survey questionnaire applied to children in the 5th and 6th grade, where it was possible to identify the trajectory school of each student and the representations and practices of their parents in relation with the school. This is a total of 837 students spread over 8 schools in the municipalities of Lisbon and Loures with different national origins. We compared the information to indigenous students, for those who have Cape Verdean origin and those of Indian origin. We conclude that family support for education (index built on the way to school meetings, the control they exert over their homework, the dialogue about school life and the support given by the families to the difficulties contributes to school performance and that the two variables vary in a direct relationship. But this is not, in any way, a sufficient condition for success or failure in school as it is not unreasonable to conclude the decisive effect of the practices of family support for education about the results students get in school. There was also a stronger relationship with the results when it comes to the students of Cape Verdean origin and more fragile with those of Indian origin.

Confounding the origin and function of mirror neurons.

2014-04-01

Cook et al. argue that mirror neurons originate in sensorimotor associative learning and that their function is determined by their origin. Both these claims are hard to accept. It is here suggested that a major role in the origin of the mirror mechanism is played by top-down connections rather than by associative learning.

What is the origin of concentration quenching of Cu"+ luminescence in glass?

International Nuclear Information System (INIS)

Jiménez, José A.

2016-01-01

Monovalent copper-doped luminescent glasses are attractive materials for white light-emitting devices, photonic waveguides, and solar spectral conversion in photovoltaic cells. However, the occurrence of concentration quenching in such is not fully understood at present. In this work, calcium-phosphate glasses with high concentrations of luminescent Cu"+ ions have been prepared by a simple melt-quench method via CuO and SnO co-doping. The aim is to elucidate the origin of concentration quenching of Cu"+ light emission. A spectroscopic characterization was carried out by optical absorption and photoluminescence (PL) spectroscopy including emission decay dynamics. The concentrations of both CuO and SnO dopants were varied as 5, 10 and 15 mol%. Monovalent copper content is estimated in the CuO/SnO-containing glasses following the assessment of the concentration dependence of Cu"2"+ absorption in the visible for CuO singly-doped glasses. Contrary to the conventionally acknowledged direct Cu"+→Cu"2"+ transfer, the data supports a Cu"+–Cu"+ energy migration channel at the origin of the PL quenching.

In a research project about work-related issues and corporate sustainability conducted in Brazil, the goal was to better understand how work-related issues were addressed in the corporate context. Particularly, there are some specific initiatives that serve as guides to organizational decisions, which make their performance indicators for the context of corporate sustainability. 1) To explore the presence of work-related issues and their origins in corporate sustainability approach, analyzing a) corporate disclosures; b) sustainability guidelines that are identified as relevant in corporate disclosures; c) documents that are related to sustainable development and also identified as key-documents for these guidelines and initiatives. 2) To present the activity-centered ergonomics and psychodynamics of work contributions to work-related issues in a corporate sustainability approach. An exploratory study based on multiple sources of evidence that were performed from 2012 to 2013, including interviews with companies that engaged in corporate sustainability and document analysis using the content analysis approach. Work-related issues have been presented since the earliest sustainable development documents. It is feasible to construct an empirical framework for work-related issues and corporate sustainability approaches. 1) Although some authors argue that corporate sustainability has its roots based only on the environmental dimension, there is strong empirical evidence showing that social dimension aspects such as work-related issues have been present since the beginning. 2) Some indicators should be redesigned to more precisely translate the reality of some workplaces, particularly those indicators related to organizational design and mental health.

The Hsk1(Cdc7) replication kinase regulates origin efficiency.

Patel, Prasanta K; Kommajosyula, Naveen; Rosebrock, Adam; Bensimon, Aaron; Leatherwood, Janet; Bechhoefer, John; Rhind, Nicholas

2008-12-01

Origins of DNA replication are generally inefficient, with most firing in fewer than half of cell cycles. However, neither the mechanism nor the importance of the regulation of origin efficiency is clear. In fission yeast, origin firing is stochastic, leading us to hypothesize that origin inefficiency and stochasticity are the result of a diffusible, rate-limiting activator. We show that the Hsk1-Dfp1 replication kinase (the fission yeast Cdc7-Dbf4 homologue) plays such a role. Increasing or decreasing Hsk1-Dfp1 levels correspondingly increases or decreases origin efficiency. Furthermore, tethering Hsk1-Dfp1 near an origin increases the efficiency of that origin, suggesting that the effective local concentration of Hsk1-Dfp1 regulates origin firing. Using photobleaching, we show that Hsk1-Dfp1 is freely diffusible in the nucleus. These results support a model in which the accessibility of replication origins to Hsk1-Dfp1 regulates origin efficiency and provides a potential mechanistic link between chromatin structure and replication timing. By manipulating Hsk1-Dfp1 levels, we show that increasing or decreasing origin firing rates leads to an increase in genomic instability, demonstrating the biological importance of appropriate origin efficiency.

Highlights: ► We study the possible separation of neighouring trajectories in the bouncing ball billiard. ► In a certain interval of frequencies semianalitical evaluations are possible. ► One may find a lower bound for the maximal Lyapunov exponent in case of a resonance. - Abstract: We present a study of the chaotic behaviour of the bouncing ball billiard. The work is realised on the purpose of finding at least certain causes of separation of the neighbouring trajectories. Having in view the geometrical construction of the system, we report a clear origin of chaoticity of the bouncing ball billiard. By this we claim that in case when the floor is made of arc of circles – in a certain interval of frequencies – one can give semi-analytical estimates on chaotic behaviour.

The origin of the eukaryotic cell

Science.gov (United States)

Hartman, H.

1984-01-01

The endosymbiotic hypothesis for the origin of the eukaryotic cell has been applied to the origin of the mitochondria and chloroplasts. However as has been pointed out by Mereschowsky in 1905, it should also be applied to the nucleus as well. If the nucleus, mitochondria and chloroplasts are endosymbionts, then it is likely that the organism that did the engulfing was not a DNA-based organism. In fact, it is useful to postulate that this organism was a primitive RNA-based organism. This hypothesis would explain the preponderance of RNA viruses found in eukaryotic cells. The centriole and basal body do not have a double membrane or DNA. Like all MTOCs (microtubule organising centres), they have a structural or morphic RNA implicated in their formation. This would argue for their origin in the early RNA-based organism rather than in an endosymbiotic event involving bacteria. Finally, the eukaryotic cell uses RNA in ways quite unlike bacteria, thus pointing to a greater emphasis of RNA in both control and structure in the cell. The origin of the eukaryotic cell may tell us why it rather than its prokaryotic relative evolved into the metazoans who are reading this paper.

Extraembryonic origin of circulating endothelial cells.

Directory of Open Access Journals (Sweden)

Luc Pardanaud

Full Text Available Circulating endothelial cells (CEC are contained in the bone marrow and peripheral blood of adult humans and participate to the revascularization of ischemic tissues. These cells represent attractive targets for cell or gene therapy aimed at improving ischemic revascularization or inhibition of tumor angiogenesis. The embryonic origin of CEC has not been addressed previously. Here we use quail-chick chimeras to study CEC origin and participation to the developing vasculature. CEC are traced with different markers, in particular the QH1 antibody recognizing only quail endothelial cells. Using yolk-sac chimeras, where quail embryos are grafted onto chick yolk sacs and vice-versa, we show that CEC are generated in the yolk sac. These cells are mobilized during wound healing, demonstrating their participation to angiogenic repair processes. Furthermore, we found that the allantois is also able to give rise to CEC in situ. In contrast to the yolk sac and allantois, the embryo proper does not produce CEC. Our results show that CEC exclusively originate from extra-embryonic territories made with splanchnopleural mesoderm and endoderm, while definitive hematopoietic stem cells and endothelial cells are of intra-embryonic origin.

Development of the nervus terminalis: origin and migration.

Science.gov (United States)

Whitlock, Kathleen E

2004-09-01

The origin of the nervus terminalis is one of the least well understood developmental events involved in generating the cranial ganglia of the forebrain in vertebrate animals. This cranial nerve forms at the formidable interface of the anteriormost limits of migrating cranial neural crest cells, the terminal end of the neural tube and the differentiating olfactory and adenohypophyseal placodes. The complex cellular interactions that give rise to the various structures associated with the sensory placode (olfactory) and endocrine placode (adenohypophysis) surround and engulf this enigmatic cranial nerve. The tortured history of nervus terminalis development (see von Bartheld, this issue, pages 13-24) reflects the lack of consensus on the origin (or origins), as well as the experimental difficulties in uncovering the origin, of the nervus terminalis. Recent technical advances have allowed us to make headway in understanding the origin(s) of this nerve. The emergence of the externally fertilized zebrafish embryo as a model system for developmental biology and genetics has shed new light on this century-old problem. Coupled with new developmental models are techniques that allow us to trace lineage, visualize gene expression, and genetically ablate cells, adding to our experimental tools with which to follow up on studies provided by our scientific predecessors. Through these techniques, a picture is emerging in which the origin of at least a subset of the nervus terminalis cells lies in the cranial neural crest. In this review, the data surrounding this finding will be discussed in light of recent findings on neural crest and placode origins. Copyright 2004 Wiley-Liss, Inc.

After the diagnosis of the AIDS symptoms, in 1981, and after the discovery of the virus that causes AIDS, in 1983, the virologists have formulated different theories about its origin. Some of them involved natural causes, e.g., HIV origin from SIV strains. Other theories go further to the possibility of a deadly man-made virus escaped from laboratories or voluntary spread by some conspirative organisations. At this moment, the scientists limits themselves to search proofs to sustain the zoonotic origin of HIV from SIV and its accomodation to human body conditions.

Orbital evolution and origin of the Martian satellites

International Nuclear Information System (INIS)

Szeto, A.M.K.

1983-01-01

The orbital evolution of the Martian satellites is considered from a dynamical point of view. Celestial mechanics relevant to the calculation of satellite orbital evolution is introduced and the physical parameters to be incorporated in the modeling of tidal dissipation are discussed. Results of extrapolating the satellite orbits backward and forward in time are presented and compared with those of other published work. Collision probability calculations and results for the Martian satellite system are presented and discussed. The implications of these calculations for the origin scenarios of the satellites are assessed. It is concluded that Deimos in its present form could not have been captured, for if it had been, it would have collided with Phobos at some point. An accretion model is therefore preferred over capture, although such a model consistent with the likely carbonaceous chondritic composition of the satellites has yet to be established. 91 references

Stable isotope values were used to develop a new analytical approach enabling the simultaneous identification of milk samples either processed with different heating regimens or from different geographical origins. The samples consisted of raw, pasteurized (HTST), and ultrapasteurized (UHT) milk from different Italian origins. The approach consisted of the analysis of the isotope ratio of δ¹³C and δ¹⁵N for the milk samples and their fractions (fat, casein, and whey). The main finding of this work is that as the heat processing affects the composition of the milk fractions, changes in δ¹³C and δ¹⁵N were also observed. These changes were used as markers to develop pattern recognition maps based on principal component analysis and supervised classification models, such as linear discriminant analysis (LDA), multivariate regression (MLR), principal component regression (PCR), and partial least-squares (PLS). The results give proof of the concept that isotope ratio mass spectroscopy can discriminate simultaneously between milk samples according to their geographical origin and type of processing.

IS WORK-FAMILY CONFLICT A MULTILEVEL STRESSOR LINKING JOB CONDITIONS TO MENTAL HEALTH? EVIDENCE FROM THE WORK, FAMILY AND HEALTH NETWORK

Purpose Most research on the work conditions and family responsibilities associated with work-family conflict and other measures of mental health uses the individual employee as the unit of analysis. We argue that work conditions are both individual psychosocial assessments and objective characteristics of the proximal work environment, necessitating multilevel analyses of both individual- and team-level work conditions on mental health. Methodology/approach This study uses multilevel data on 748 high-tech professionals in 120 teams to investigate relationships between team- and individual-level job conditions, work-family conflict, and four mental health outcomes (job satisfaction, emotional exhaustion, perceived stress, and psychological distress). Findings We find that work-to-family conflict is socially patterned across teams, as are job satisfaction and emotional exhaustion. Team-level job conditions predict team-level outcomes, while individuals’ perceptions of their job conditions are better predictors of individuals’ work-to-family conflict and mental health. Work-to-family conflict operates as a partial mediator between job demands and mental health outcomes. Practical implications Our findings suggest that organizational leaders concerned about presenteeism, sickness absences, and productivity would do well to focus on changing job conditions in ways that reduce job demands and work-to-family conflict in order to promote employees’ mental health. Originality/value of the chapter We show that both work-to-family conflict and job conditions can be fruitfully framed as team characteristics, shared appraisals held in common by team members. This challenges the framing of work-to-family conflict as a “private trouble” and provides support for work-to-family conflict as a structural mismatch grounded in the social and temporal organization of work.

2009-05-01

Siegrists concept of effort-reward imbalance (ERI) had been shown to be associated with a broad range of health impairments, in particular cardiovascular diseases and depression. The original questionnaire was designed to assess ERI in the field of occupational work. This paper reports on a newly developed questionnaire for the assessment of ERI in household and family work. Analogous to the original version, it is divided into two components: (i) dysbalance of effort and reward (extrinsic component), and (ii) over-commitment (intrinsic components). The questionnaire was tested with data drawn from a clinical sample of mothers (n = 567) in rehabilitation clinics. Factor analyses have reproduced the two main dimensions "effort" and "reward". Relevant aspects of reward at home were (i) meaningfulness, (ii) social gratification, (iii) appreciation from the spouse, and (iv) affection for the child. Finally a 19-item questionnaire for assessing ERI in household and family work (ERI-M) and a four-item measure for measuring parental over-commitment (Over-M) are available. The psychometric properties of both instruments are good to satisfactory.

Power, Ethnic Origin, and Sexual Objectification

Full Text Available In this study, we investigated the effects of primed power on sexual objectification of Caucasian and Asian men and women. As in previous studies, sexual objectification was assessed using an inversion paradigm with face–body compound stimuli. Previous work has shown that participants primed to power do not show the typical drop in recognition performance for inverted face–body compound stimuli, suggesting that they process these stimuli in terms of their individual features, in a manner akin to objects, and quite different from the way in which faces and bodies are normally processed (i.e., configurally. Caucasian male and female participants were primed to high or neutral-power before engaging in an old/new recognition task involving sexualized face–body compound images of Caucasian and Asian men and women. Participants primed to high-power showed a decreased inversion effect for Caucasian models of the opposite gender, but not for Asian models. Thus, power exerts different effects on this specific type of social perception, depending on the ethnic origin of the target. We discuss our results in the context of the extant literature on power and with reference to media stereotyping of Caucasians and Asians.

Full Text Available Pristine Ag3PO4 microspheres were synthesized by a co-precipitation method, followed by being calcined at different temperatures to obtain a series of calcined Ag3PO4 photocatalysts. This work aims to investigate the origin of activity and stability enhancement for Ag3PO4 photocatalyst after calcination based on the systematical analyses of the structures, morphologies, chemical states of elements, oxygen defects, optical absorption properties, separation and transfer of photogenerated electron-hole pairs, and active species. The results indicate that oxygen vacancies (VO˙˙ are created and metallic silver nanoparticles (Ag NPs are formed by the reaction of partial Ag+ in Ag3PO4 semiconductor with the thermally excited electrons from Ag3PO4 and then deposited on the surface of Ag3PO4 microspheres during the calcination process. Among the calcined Ag3PO4 samples, the Ag3PO4-200 sample exhibits the best photocatalytic activity and greatly enhanced photocatalytic stability for photodegradation of methylene blue (MB solution under visible light irradiation. Oxygen vacancies play a significantly positive role in the enhancement of photocatalytic activity, while metallic Ag has a very important effect on improving the photocatalytic stability. Overall, the present work provides some powerful evidences and a deep understanding on the origin of activity and stability enhancement for the Ag3PO4 photocatalyst after calcination.

`Sex' – It's not only Women's Work: A Case for Refocusing on the Functional Role that Sex Plays in Work for both Women and Men

Mention of the term sex work often invokes images of marginalized women at risk for HIV infection. Such images, however, are counterintuitive to the functional role intended by the movement that spawned use of the terms `sex work' and `sex worker'. This article looks at the sexual practices of men in urban China to argue for a return to a functional definition of `sex work', which was originally meant to legitimize the role sex plays in work. The progenitors of this movement intended to use `sex work' as a means to legitimize sex as an income generating activity for women involved in prostitution. I show that sex can also serve a functional role in the work-related duties of men seeking economic and political success in contemporary urban China. Men in China utilize sex as one way for demonstrating the loyalty necessary to access state-owned and controlled resources in a market economy governed under a Leninist system. Overall the article demonstrates that reclaiming perception of sex work as a functional rather than behavioral category can expand its use for preventing HIV among the broad subset of people who engage in sex as part of their work.

X-ray diffraction experiments have shown that sodium exhibits a dramatic pressure-induced drop in melting temperature, which extends from 1000 K at ˜30GPa to as low as room temperature at ˜120GPa. Despite significant theoretical effort to understand the anomalous melting, its origins are still debated. In this work, we reconstruct the sodium phase diagram by using an ab initio quality neural-network potential. Furthermore, we demonstrate that the reentrant behavior results from the screening of interionic interactions by conduction electrons, which at high pressure induces a softening in the short-range repulsion.

Ideas and integrity; how ideas of what is important influence scholarly work

Recent big cases of scientific misconduct have led to an increase in debates about integrity of scientists and their work. These cases do not originate out of nothing but are the extremes of trends in contemporary science. Inspired by the Weberian notion about the functioning of ideas in the conduct

Study of antiproton flux of atmospheric origin in neighbourhood of the earth

Secondary atmospheric antiprotons are studied. A parametrisation of the inclusive cross section for the p-bar production in p + p and p + A collisions is developed, based on the Quark Counting Rule, the Regge Phenomenology and data fitting. This parametrisation is shown to have a good agreement with experimental data for incident nucleon energy at least up to 24 GeV/n in the laboratory frame. By the analysis of the p-bar mean multiplicity distribution, this parametrisation can extend at least up to the centre of mass energy √s ∼ 25 GeV. Based on this well developed parametrisation, the Wounded Nucleon Model is applied to obtain the p-bar production cross section in A + A collisions. By including cosmic protons and α particles, the atmospheric p-bar flux at high balloon and satellite altitudes are calculated. The He-induced collisions are shown to contribute about 30 % in the total secondary atmospheric p-bar flux. It is observed that, for the search of the p-bar exotic origins such as the annihilation of supersymmetric dark matter (neutralino) and the evaporation of primordial black holes, the energy range up to E = 200 GeV/n for cosmic particles generating the secondary atmospheric p-bar production is the most important. It is shown that the secondary atmospheric p-bar flux used to correct the p-bar flux at TOA was underestimated in the previous works. In this work, the p-bar flux at TOA is then modified 10-15 % lower than the originally deduced, for the energy range E k > 1 GeV. A p-bar measurement experiment at the ground level is used to test the accuracy of secondary atmospheric p-bar production calculated by different works. The results of the BESS 1999 experiment at 2.77 km have confirmed the correctness of the present approach. At the AMS altitude, it is shown that the p-bar flux measured by AMS is almost the exact p-bar flux at TOA, with only 2-3 % of the atmospheric p-bar component. It is found that, even at very high altitudes, thousands of

This dissertation examines intermarriage across generations of the Mexican-origin population in order to better understand how this population is incorporating in U.S. society, and looks at parental migration status and parental nativity as factors that may impede or facilitate intermarriage incorporation. Using data from the Immigration and Intergenerational Mobility in Metropolitan Los Angeles (IIMMLA) survey the research shows that: the majority of intermarriages among the Mexican-origin ...

Is supersymmetric origin of monojets viable

Nandi, S.

1985-01-01

The laboratory and cosmological bounds on the masses of the scalar leptons and the photino are used to put constraints on the supersymmetric origin of the CERN monojets. The latest MAC data at PEP exclude the scalar quarks, of masses up to 45 GeV, as the origin of these monojets; the cosmological bounds, for a stable photino, exclude the mass range necessary for the gq production interpretation

Honeydew Honeys: A Review on the Characterization and Authentication of Botanical and Geographical Origins.

The commercial interest in honeydew honeys (from the secretions of plants or the excretions of plant-sucking insects found on plants) is increasing because of their higher therapeutic properties compared with those of most blossom honeys (from nectar). However, honeydew honeys have been less studied than blossom honeys. In this work, studies carried out to characterize and authenticate honeydew honeys by their botanical and geographical origins have been reviewed. The identification of honey origins has been approached by two ways: by the analysis of chemical markers and by the development of analytical methodologies combined with multivariate analyses. Some compounds have been suggested as specific botanical markers of several honeydew honeys, such as quercitol and trans-oak lactone for oak honey, 2-aminoacetophenone and propylanisol for holm oak honey, and 1-chloro-octane and tridecane for pine honey. The presence of 3-carene and an unidentified compound in samples was proposed as a way discriminate between Greek and Turkish pine honeys. Chemometric analyses have been applied on chemical compositions and on physicochemical, microscopic, and spectral parameters and have proved to be valuable methods for authenticating honeydew honeys. Analytical methods based on spectral information are suitable for the routine control of honeydew-honey origins because they are fast and require easy sample preparations.

Planet formation theory is recalled. The different existing hypothesis on the moon's origins are reviewed also to see how much they are compatible with the planet formation theory. Up to now, the giant impact model seems to be the only model to satisfy all the constraints. Computerized simulation results have been presented in colloquiums and their scenarios are recalled [fr
