    María Victoria Flores Trujillo

    2016-07-01

    Full Text Available Globalization is defined as a process that integrates knowledge worldwide, has its historical reference on changes in the ways processes, methods and information are addressed; documented its inception in the late twentieth century, Castells, M. (2001 beyond the discrepancy about whether it is a product of technological development or an inevitable evolution of capitalism, research arises from the formulation of the following questions: How important is the study of globalization ?, What has produced important contributions in the scientific community about globalization? And What are the perspectives or approaches addressed? . This work aims to show how the scientific community has produced knowledge about this phenomenon addressing the political, economic and social approaches: From the economic point of view reconfigures how to address the processes of production, distribution and consumption of goods and services in the world, permeating this way all international economic events. From the political point of view, besides the redistribution of emerging geopolitical blocs, it establishes a new category of state, transnational state. From the social point of view, it shows evidence of the negative effects of globalization on resizing the category personal, local or regional or even in global risk-Global group. The research is documentary literature, their contribution to social science evidence to characterize globalization as political, economic and social phenomenon of the century that permeates all areas of study applied.

  3. Economic Globalization - a Phenomenon of Global Business Integration

    Full Text Available Tumultuous economic life led scientists to seek explanations to the negative economic events,events that take many forms, and to whom it is a must to find a solution or even a mitigating factor. Thefoundation of the economy has undergone many changes. The recent events manifested in the world economyshow that the underlying fundamentals of this science must be revised because they proved to be wrong. Itnotes several times, mainly due to present economic crisis, that currently the economics have no theoreticaland practical means and no tools of analysis and intervention in the economy, proving that the existing onesare exceeded and insufficient, so that the creation of an unifying principle and of some generalizing conceptsthat could systematize and forecast the current economic phenomena in the microeconomics andmacroeconomics, especially in the transnational companies field, those which are the base of the foreigndirect investment flows, should become the main objective of the new economic science. Through this paper,we tried to illustrate the important aspects of economic globalization, the challenges that this phenomenonposes to economies and the way in which an economy can become globally competitive, under massiveconstraints of the global competition, how a national company can become globally integrated, study basedon representative references.

  4. Global Media, Biopolitics and Affect

    Knudsen, Britta Timm; Stage, Carsten

    Global Media, Biopolitics and Affect shows how mediations of bodily vulnerability have become a strong political force in contemporary societies. In discussions and struggles concerning war involvement, healthcare issues, charity, democracy movements, contested national pasts, and climate change...... culture. Likewise, it presents a range of close empirical case studies in the areas of illness blogging, global protests after the killing of Neda Agda Soltan in Iran, charity communication, green media activism, online war commemoration and digital witnessing related to conflicts in Sarajevo and Ukraine......., performances of bodily vulnerability is increasingly used by citizens to raise awareness, create sympathy, encourage political action, and to circulate information in global media networks. The book thus argues that bodily vulnerability can serve as a catalyst for affectively charging and disseminating...

  6. Bollywood Dreams? The Rise of the Asian Mela as a Global Cultural Phenomenon

    Melanie Smith

    2006-03-01

    Full Text Available This article will examine some of the complexities inherent in the development of Asian Mela festivals from small-scale community-based events in India, to national celebrations of Diasporic culture in Western countries. Like Caribbean Carnivals, Melas are becoming more popular as a global cultural tourism phenomenon and are increasingly being promoted to white and tourist audiences. This similarly engenders fears of cultural dilution, distortion, and ‘Othering’. The programming of Melas is apparently keeping pace with the exporting, re-packaging and hybridisation of other forms of Asian culture, such as cuisine, music, fashion, and cinema. But does this symbolise a Bollywood dream or just another post-colonial appropriation of indigenous or Disaporic cultures? Cultural protectionism is certainly a contentious issue within Diasporic communities, where inter-generational differences of opinion can lead to conflict and confusion. Identity construction is complex and worthy of further examination in the context of Melas, which traditionally served to celebrate ethnic community and folk cultures and identities, but are increasingly becoming a showcase for global and hybridised cultural forms. The article will examine these issues, as well as providing an analysis of the factors and mechanisms that are driving the development of Melas forward. This will include the role and vision of artistic directors of Melas, the contribution of ethnic communities to cultural continuity, and issues relating to audience and tourism development. A case study of the Edinburgh Mela will be presented, which exemplifies a number of the aforementioned issues, focusing in particular on national and Diasporic identity construction, and the tensions between popular and traditional cultural forms.

  9. Problems posed by the development of the Oklo phenomenon: tentative global interpretation

    Naudet, R.

    This paper discusses the basic problems posed by the development of the Oklo phenomenon: the conditions in which the reactions are triggered and propagated and how they have been controlled. The reactions were maintained by the destruction of neutron poisons in the ore and were controlled by temperature. Oklo is made up of a large number of contiguous reactors. Geological problems of the origin of the clays, desilification, and uranium concentration are discussed. Oklo is shown to be a very complex phenomenon which developed in space and time. Besides the thermal, neutron, and geochemical coupling, there is also a tectonic coupling

  10. INVESTIGATING THE COLLECTIVE ONLINE purchase PHENOMENON: FACTORS AFFECTING THE SHOPPING INTENSITY

    Everton Roberto Comin

    2014-04-01

    Full Text Available The collective online shopping is a recent phenomenon in Brazil whose objective is to sell products and services for a minimum number of consumers. This study aims to investigate whether the intensity of collective online shopping is influenced by the aspects consumer interest in online collective shopping, impulse buying and insecurity. The data collection was based on a questionnaire with closed questions with multiple choices and a 5-point Likert scale.The final sample is composed of 143 respondents. Data was analyzed through the following statistic techniques: exploratory data analysis, exploratory factor analysis, reliability analysis, and logistic regression. The results suggest that people more interest in collective shopping are more likely to make collective shopping. People who feel greater insecurity in navigating the website is less likely to make collective shopping. It was observed that there is no a positive relationship between impulse shopping and collective purchasing. Some limitations include the number of constructs and sample characteristics.

  11. How the mach phenomenon and shape affect the radiographic appearance of skeletal structures

    Papageorges, M.

    1991-01-01

    The shape of skeletal structures and their position relative to the x-ray beam have a considerable effect on their radiographic appearance. Depending on the thickness of the cortical or subchondral bone, skeletal structures display the characteristics of either homogeneous or compound lamellar structures. Convex homogeneous structures are associated with a negative Mach line, and concave homogeneous structures are associated with a positive Mach line. Convex compound lamellar structures are associated with a negative Mach band and visualization of the lamina (subchondral or cortical bone) is reduced. Concave compound lamellar structures are associated with a positive Mach band and visualization of the lamina is enhanced. The combined effect of Mach phenomenon, shape, and thickness enhances visualization of some skeletal surfaces and make others imperceptible. These principles are very useful to correctly identify complex skeletal structures and avoid misinterpretations

  13. The Phenomenon of Financial Economics: Russia and the World Are in Current Global Turbulence

    Valentine P. Akinina

    2009-12-01

    Full Text Available The article deals with the analysis of the current situation on the global financial arena, analyzing the chain of cause and effect of the origins of the economic crisis and providing its possible logical outcomes. We are trying to prove here that the way the world economic situation develops will lead to either further growth or stagnation of national economies and define their position in the global business, financial, and social spheres.

    We provide an analysis of the serious transformations financial economics have been undergoing at the end of the 20th and beginning of the 21st centuries. All these changes, such as the development of international fusions on financial markets, the creation of new financial instruments, products and services, and others, have been caused largely by (and also have led to significant events in the global political arena. However, regardless of the transformations, world leadership remains in the hands of US government and business and that of their closest partners, while those societies that are not willing to support the “Americanized” world order end up on the blacklist of the World Bank, the IMF, and other international financial institutions.

    Finally, the article provides our views of the possible ways of dealing with the global economic stagnation. We highlight the importance of the strong and careful supervision of any global as well as national financial activities, the education of the public on the issues of wise investments, and the dangers of living on credit.

  15. Editorial Perspective: Pathological social withdrawal during in adolescence: a culture-specific or a global phenomenon?

    Li, Tim M H; Wong, Paul W C

    2015-10-01

    Impairing patterns of long-term adolescent social withdrawal and self-exclusion, including nonattendance at school or work, and minimal social contact, have been identified as a significant clinical and social problem in Japan since the late 1990s, where it is termed hikikomori. As well clinical impairment for the withdrawn youths and burden for the families, hikikomori has brought societal and health service costs in Japan. Since its first identification, similar cases have been reported in other countries. Socially withdrawn youths, unfortunately, are difficult to identify and their risks can be 'invisible' because of their withdrawn nature and the traditional perspective of what is perceived as at-risk youth. Understanding of the issue including its causes, risks, and outcomes is very limited. In this editorial perspective, we highlight how youth social withdrawal is becoming a clinical and social concern in some parts of the world and respond to the lack of research on this issue by synthesizing some of the basic research findings, and suggesting future directions for research and practice relating to this emerging youth phenomenon in middle-and-high-income countries in the hope of bringing more attention to this issue. © 2015 Association for Child and Adolescent Mental Health.

  16. Herding: a new phenomenon affecting medical decision-making in multiple sclerosis care? Lessons learned from DIScUTIR MS.

    Saposnik, Gustavo; Maurino, Jorge; Sempere, Angel P; Ruff, Christian C; Tobler, Philippe N

    2017-01-01

    Herding is a phenomenon by which individuals follow the behavior of others rather than deciding independently on the basis of their own private information. A herding-like phenomenon can occur in multiple sclerosis (MS) when a neurologist follows a therapeutic recommendation by a colleague even though it is not supported by best practice clinical guidelines. Limited information is currently available on the role of herding in medical care. The objective of this study was to determine the prevalence (and its associated factors) of herding in the management of MS. We conducted a study among neurologists with expertise in MS care throughout Spain. Participants answered questions regarding the management of 20 case scenarios commonly encountered in clinical practice and completed 3 surveys and 4 experimental paradigms based on behavioral economics. The herding experiment consisted of a case scenario of a 40-year-old woman who has been stable for 3 years on subcutaneous interferon and developed a self-limited neurological event. There were no new magnetic resonance imaging (MRI) lesions. Her neurological examination and disability scores were unchanged. She was advised by an MS neurologist to switch from interferon to fingolimod against best practice guidelines. Multivariable logistic regression analysis was conducted to evaluate factors associated with herding. Out of 161 neurologists who were invited to participate, 96 completed the study (response rate: 60%). Herding was present in 75 (78.1%), having a similar prevalence in MS experts and general neurologists (68.8% vs 82.8%; P =0.12). In multivariate analyses, the number of MS patients seen per week was positively associated with herding (odds ratio [OR] 1.08, 95% CI 1.01-1.14). Conversely, physician's age, gender, years of practice, setting of practice, or risk preferences were not associated with herding. Herding was a common phenomenon affecting nearly 8 out of 10 neurologists caring for MS patients. Herding may

  18. INSTITUTIONAL GLOBALIZATION AS A SYSTEM OF INTEGRATION THE PHENOMENON OF THE POSTMODERN DEVELOPMENT

    V. V. Zinchenko

    2015-12-01

    Full Text Available Purpose. Institutionalism is gaining strength as a dominant point of view on the world. Its philosophical basis is the postulate of the uncertainty of the development, which comes to replace the neoclassical certainty characteristic of industrial society. The postulate of uncertainty is closely connected with the idea of subjectivization and individualization of post-industrial society. All these were very important components of the new paradigm, although they do not exhaust the problem. In the heart of postmodernism is a mass identity as a spiritual substance, while the more recently mass of people to realize themselves as natural and social beings. Person has absolute freedom in the acceptance and rejection of culture and civilization; it is pluralistic in their actions and in their consciousness. It is the subject of history and it should be creative, fluent mastering all the achievements of culture. Methodology. The dialogue system of the Postmodern, which is the basis of human communication with another person, human with society is a model of convergent formation of the world community and world economy. The same model of rationalism and adequate industrial society is a monologue, which is easily builds a bridge to violence, even if it is carried out in the name of the man behind him and the pathos of the exaltation of man as the bearer of unlimited creation possibilities. However, it is very important not just to modify rationalism, and to understand the origins of civilization. Scientific novelty. The postmodern era begins is not easy. Modern defending, using all their reserves: public thirst for justice, the priority of rationality (at least in the economy, monologist public agencies and politicians in contrast to the dialogic postmodern imperative modality in the spiritual existence of man instead the freedom. Finally, the world of the story is set a trap – the anthropological paradigm of the globalization ideology formation. In

    The coronary slow flow phenomenon (CSFP) is defined as a delayed distal vessel contrast opacification in the absence of obstructive epicardial coronary artery disease during coronary angiography. There is conflicting data in medical literature regarding the effects of CSFP on the left ventricular functions assessed by conventional echocardiography or tissue Doppler imaging. Therefore, we aimed to evaluate whether there is any abnormality in the myocardial deformation parameters (strain, strain rate (SR), rotation, twist) of the left ventricle obtained by speckle tracking echocardiography (STE) in patients with CSFP. Twenty patients with CSFP were included prospectively in the study. Another 20 patients with similar demographics and cardiovascular risk factors as well as normal coronary angiography were used as the control group. Two-dimensional echocardiographic images of the left ventricle from the apical long-axis, two-chamber, four-chamber, and parasternal short-axis views were used for STE analysis. The analysis of left ventricular circumferential deformation parameters showed that the averaged peak systolic strain, systolic SR, and early diastolic SR values were significantly lower in patients with CSFP (P = 0.009, P = 0.02, and P = 0.02, respectively). Among the left ventricular rotation and twist values, apical rotation was significantly lower in patients with CSFP (P = 0.02). Further, the mean thrombolysis in myocardial infarction frame count value was found to be negatively correlated with the averaged peak circumferential early diastolic SR (r = -0.35, P = 0.03). It was positively correlated with the averaged peak circumferential systolic strain (r = 0.47, P = 0.003) and circumferential systolic SR (r = 0.46, P = 0.005). Coronary slow flow phenomenon leads to significant alterations in the myocardial deformation parameters of the left ventricle as assessed by STE. Specifically, circumferential deformation parameters are affected in CSFP patients. © 2015

  1. The Emerging Amphibian Fungal Disease, Chytridiomycosis: A Key Example of the Global Phenomenon of Wildlife Emerging Infectious Diseases.

    Kolby, Jonathan E; Daszak, Peter

    2016-06-01

    The spread of amphibian chytrid fungus, Batrachochytrium dendrobatidis, is associated with the emerging infectious wildlife disease chytridiomycosis. This fungus poses an overwhelming threat to global amphibian biodiversity and is contributing toward population declines and extinctions worldwide. Extremely low host-species specificity potentially threatens thousands of the 7,000+ amphibian species with infection, and hosts in additional classes of organisms have now also been identified, including crayfish and nematode worms.Soon after the discovery of B. dendrobatidis in 1999, it became apparent that this pathogen was already pandemic; dozens of countries and hundreds of amphibian species had already been exposed. The timeline of B. dendrobatidis's global emergence still remains a mystery, as does its point of origin. The reason why B. dendrobatidis seems to have only recently increased in virulence to catalyze this global disease event remains unknown, and despite 15 years of investigation, this wildlife pandemic continues primarily uncontrolled. Some disease treatments are effective on animals held in captivity, but there is currently no proven method to eradicate B. dendrobatidis from an affected habitat, nor have we been able to protect new regions from exposure despite knowledge of an approaching "wave" of B. dendrobatidis and ensuing disease.International spread of B. dendrobatidis is largely facilitated by the commercial trade in live amphibians. Chytridiomycosis was recently listed as a globally notifiable disease by the World Organization for Animal Health, but few countries, if any, have formally adopted recommended measures to control its spread. Wildlife diseases continue to emerge as a consequence of globalization, and greater effort is urgently needed to protect global health.

  3. A Correlational Study of How Airline Customer Service and Consumer Perception of Airline Customer Service Affect the Air Rage Phenomenon

    Hunter, Joyce A.

    2007-01-01

    Between 1995 and 2000, customer service declined throughout the airline industry, as reported in February 2001 by the U.S. Department of Transportation (2001). One of the biggest problems today within the airline industry is the constant complaining from customers regarding the deterioraton of service (McCollough, Berry, & Yadav, 2000). Since 1995, unfortunately no airline has been immune from service deterioration, as reported by the Airline Quality Rating, an annual report by two airline industry experts who analyzed Department of Transportation statistics (Harrison & Kleinsasser, 1999). The airline' refusal to recognize the issue of customer service has perpetuated an environment that has become dangerous and detrimental to the traveling public as well as to airline employees, which in turn has fueled a new phenomenon, now referred to as "air rage".

  6. Is physical water scarcity a new phenomenon? Global assessment of water shortage over the last two millennia

    Kummu, Matti; Varis, Olli; Ward, Philip J; De Moel, Hans

    2010-01-01

    In this letter we analyse the temporal development of physical population-driven water scarcity, i.e. water shortage, over the period 0 AD to 2005 AD. This was done using population data derived from the HYDE dataset, and water resource availability based on the WaterGAP model results for the period 1961-90. Changes in historical water resources availability were simulated with the STREAM model, forced by climate output data of the ECBilt-CLIO-VECODE climate model. The water crowding index, i.e. Falkenmark water stress indicator, was used to identify water shortage in 284 sub-basins. Although our results show a few areas with moderate water shortage (1000-1700 m 3 /capita/yr) around the year 1800, water shortage began in earnest at around 1900, when 2% of the world population was under chronic water shortage ( 3 /capita/yr). By 1960, this percentage had risen to 9%. From then on, the number of people under water shortage increased rapidly to the year 2005, by which time 35% of the world population lived in areas with chronic water shortage. In this study, the effects of changes in population on water shortage are roughly four times more important than changes in water availability as a result of long-term climatic change. Global trends in adaptation measures to cope with reduced water resources per capita, such as irrigated area, reservoir storage, groundwater abstraction, and global trade of agricultural products, closely follow the recent increase in global water shortage.

  7. Fifty Shades of African Lightness: A Bio-psychosocial Review of the Global Phenomenon of Skin Lightening Practices.

    Jacobs, Meagan; Levine, Susan; Abney, Kate; Davids, Lester

    2016-12-31

    Skin-lightening is an aesthetic practice of global concern. By adopting a biopsycho-social approach, we consider the interplay between the biological, psychological and social factors that underpin the circulation and consumption of skin lighteners in South Africa. This paper reflects on biological aspects of skin lightening, interpersonal relationships, individual beliefs and expectations about the maintenance of health and well being that informs cosmetic practices. The paper seeks to examine claims made by historians (Thomas) and political philosophers and activists (Biko) that colonialism and apartheid in South Africa historically reinforced the use of skin lightening products in the country. The paper also investigates the role of media in staking out the boundaries of beauty. We argue that men and women practice skin-lightening not only as a complex result of the internalization of global standards of beauty, but meshed with a national politics of race and colorism. Banning skin lightening products without understanding the biological effects but also the social forces that underlie their increased popularity will prove futile. Moreover, we must consider the immeasurable pleasures associated with lightening, and the feelings with achieving visibility in South Africa, a country that continues to wrestle with blackness.

    由于计算机网络等通讯媒体的广泛使用以及经济的全球化,人们的社会交往模式发生了革命性的变化,即突破国家的界限,形成了以个体为核心的全球性的社会交往模式。“微全球化”研究是一种基于微观视野的全球化研究.其一般模式和共同特点是把个人层面上涉及跨国界和跨文化的行为、交往、关系等方面的变化作为其研究的切入点,并进而把握某种跨国界和跨文化的行为、交往、关系。“微全球化”现象泛见于与青年群体相关的各种活动和事件中,对青年的发展具有积极的推动作用。%Due to the widespread use of the computer networks and other high tech communications, as well as economic globalization, people's social interaction model has undergone a revolutionary change, that is, to break through the boundaries of the countries and generate the individual-based global social interaction mode. With consideration of the impact on the youth in China with such social phenomenon, this article puts forward the concept of "micro-globalization". The study of "micro-globalization" is a study of globalization based on microscopic vision, with its focus on the personal level involving cross-border and cross-cultural behavior, to put changes of contacts and relationships as the entry point of its research and then grasp a general pattern and a common feature of certain behavior of cross-border as well as cross-cultural exchanges. From the sociological perspective with the individual as the unit of analysis, the study, stressing on the global system and highlighting the diversity of social interactions as well as worldwide multidimensional activities, may establish a new paradigm and observe a new perspective.

    Do you think the LHC is super duper fly? Does it make you want to compose some slick rhymes and bust out some killer beats? It did for one CERN rapper, and the results have become a YouTube smash hit! Katie McAlpine will sing for the CMS party on 24 September, and for the ATLAS Fest on 4 October.The Large Hadron Rap, to give it its full name, is the brainchild of AlpineKat, AKA Katie McAlpine, who is currently working for ATLAS e-News and outreach. To date, the YouTube video rap has been viewed more than 2.5 million times, to say nothing of the media coverage. Featured in newspapers around the world, including the New York Times in the US, The Telegraph in the UK and Geneva’s very own Matin Bleu, the rap is officially a sensation! Katie wrote the inspired (and pretty accurate) physics lyrics during her commute on the number 56 bus between Geneva and CERN.

    2003-01-01

    This paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries. The results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles. The evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries. One striking resu...

  13. Will EU Biofuel Policies affect Global Agricultural Markets?

    Banse, M.; Vvan Meijl, H.; Tabeau, A.; Woltjer, G.

    2008-04-01

    This paper assesses the global and sectoral implications of the European Union Biofuels Directive (BFD) in a multi-region computable general equilibrium framework with endogenous determination of land supply. The results show that, without mandatory blending policies or subsidies to stimulate the use of biofuel crops in the petroleum sector, the targets of the BFD will not be met in 2010 and 2020. With a mandatory blending policy, the enhanced demand for biofuel crops has a strong impact on agriculture at the global and European levels. The additional demand from the energy sector leads to an increase in global land use and, ultimately, a decrease in biodiversity. The development, on the other hand, might slow or reverse the long-term process of declining real agricultural prices. Moreover, assuming a further liberalization of the European agricultural market imports of biofuels are expected to increase to more than 50% of the total biofuel demand in Europe

    Full Text Available Moral harassment at the workplace has become in the last period a very often met phenomenon that severely affects the work relations and represents a significant health and safety danger. This problem has become in the last period an important issue for the European Union which has initiated a series of studie for analyzing the consequences of this pehenomenon on the normal process of the work relations, that has lead, in its turn to an awareness of this new dimenion of harassment between the employees at the internal level.

  17. The rise of global warming skepticism: exploring affective image associations in the United States over time.

    Smith, Nicholas; Leiserowitz, Anthony

    2012-06-01

    This article explores how affective image associations to global warming have changed over time. Four nationally representative surveys of the American public were conducted between 2002 and 2010 to assess public global warming risk perceptions, policy preferences, and behavior. Affective images (positive or negative feelings and cognitive representations) were collected and content analyzed. The results demonstrate a large increase in "naysayer" associations, indicating extreme skepticism about the issue of climate change. Multiple regression analyses found that holistic affect and "naysayer" associations were more significant predictors of global warming risk perceptions than cultural worldviews or sociodemographic variables, including political party and ideology. The results demonstrate the important role affective imagery plays in judgment and decision-making processes, how these variables change over time, and how global warming is currently perceived by the American public. © 2012 Society for Risk Analysis.

  18. Modeling of conductive particle motion in viscous medium affected by an electric field considering particle-electrode interactions and microdischarge phenomenon

    Eslami, Ghiyam; Esmaeilzadeh, Esmaeil; Pérez, Alberto T.

    2016-10-01

    Up and down motion of a spherical conductive particle in dielectric viscous fluid driven by a DC electric field between two parallel electrodes was investigated. A nonlinear differential equation, governing the particle dynamics, was derived, based on Newton's second law of mechanics, and solved numerically. All the pertaining dimensionless groups were extracted. In contrast to similar previous works, hydrodynamic interaction between the particle and the electrodes, as well as image electric forces, has been taken into account. Furthermore, the influence of the microdischarge produced between the electrodes and the approaching particle on the particle dynamics has been included in the model. The model results were compared with experimental data available in the literature, as well as with some additional experimental data obtained through the present study showing very good agreement. The results indicate that the wall hydrodynamic effect and the dielectric liquid ionic conductivity are very dominant factors determining the particle trajectory. A lower bound is derived for the charge transferred to the particle while rebounding from an electrode. It is found that the time and length scales of the post-microdischarge motion of the particle can be as small as microsecond and micrometer, respectively. The model is able to predict the so called settling/dwelling time phenomenon for the first time.

  19. Global life satisfaction predicts ambulatory affect, stress, and cortisol in daily life in working adults.

    Smyth, Joshua M; Zawadzki, Matthew J; Juth, Vanessa; Sciamanna, Christopher N

    2017-04-01

    Global life satisfaction has been linked with long-term health advantages, yet how life satisfaction impacts the trajectory of long-term health is unclear. This paper examines one such possible mechanism-that greater life satisfaction confers momentary benefits in daily life that accumulate over time. A community sample of working adults (n = 115) completed a measure of life satisfaction and then three subsequent days of ecological momentary assessment surveys (6 times/day) measuring affect (i.e., emotional valence, arousal), and perceived stress, and also provided salivary cortisol samples. Multilevel models indicated that people with higher (vs. lower) levels of life satisfaction reported better momentary affect, less stress, marginally lower momentary levels and significantly altered diurnal slopes of cortisol. Findings suggest individuals with high global life satisfaction have advantageous daily experiences, providing initial evidence for potential mechanisms through which global life satisfaction may help explain long-term health benefits.

    2017-04-01

    Jealousy is a heterogenous emotion on a spectrum from normality to psychopathology. The relationship between different jealousy subtypes/dimensions and affective temperaments remain unknown. In addition, few large surveys have investigated the associations between jealousy subtypes and psychopathological dimensions. A Brazilian Portuguese version of the "Questionario della Gelosia" (QUEGE) was developed. We obtained data from an anonymous web-based research platform. Socio-demographic data was obtained and participants answered the QUEGE, the TEMPS-Rio de Janeiro, and the Symptom Checklist-90-Revised (SCL-90-R). 2042 participants (29% men, 71% female, mean age+SD: 28.9±8.8 years), took part in this survey. Confirmatory factor analysis provided a five-factor model for the QUEGE with self-esteem, paranoia, interpersonal sensitivity, fear of being abandoned, and obsessive dimensions. The anxious, irritable, cyclothymic, and depressive temperaments were independently associated with jealousy dimensions, whereas the hyperthymic temperament was associated with lower scores on the self-esteem jealousy dimension (N=2042, PJealousy subtypes were dissimilarly associated with SCL-90R psychopathological dimensions, whereas the 'obsessive' jealousy dimension was not significantly associated with SCL-90R dimension scores. We found no independent influence of gender across any jealousy dimension. A convenience web-based sample was employed. Cross-sectional design precludes the establishment of causal inferences. Our data indicate that a five-factor solution may provide the best-fit model for the QUEGE. Different jealousy subtypes were independently associated with affective temperaments and psychopathological dimensions. These associations reported herein should be confirmed in prospective studies.

  5. Raynaud’s phenomenon

    F. Ingegnoli

    2011-09-01

    Full Text Available Raynaud’s phenomenon (RP is a vasospastic disorder characterized by episodic color changes of blanching, cyanosis, and hyperemia in response to cold and/or emotional stress. Although most typically noted in the fingers, the circulation of the toes, ears, nose and tongue is also frequently affected. Population studies have shown that RP in adults is more common in women than men, with prevalence estimates ranging from 4% to 30%. Geographic variations in the prevalence reflect differences in climate. RP may be a primary or a secondary process. LeRoy and Medsger suggested criteria for primary RP: symmetric attacks, the absence of tissue necrosis, ulceration or gangrene, the absence of a secondary cause, negative antinuclear antibodies, normal nailfold capillaroscopy and a normal erythrocyte sedimentation rate. Secondary RP is characterized by an age of onset of more than 30 years, painful and asymmetric attacks, ischemic skin lesions, positive autoautoantibodies, capillaroscopic abnormalities and/or clinical features suggestive of connective tissue diseases (CTDs. Among the CTDs, systemic sclerosis has the highest frequency of RP. Finding a cause for RP requires a knowledge of the patient’s occupational, smoking, drug history, physical examination, nailfold capillaroscopy, routine laboratory tests and autoantibodies. Furthermore, RP should be distinguished from acrocyanosis, a condition characterized by continuous cyanosis of the hands or feet that is aggravated by cold temperature. The most important instruction to the patient is abstinence from any smoking, offending drugs should be discontinued, and abrupt changes in temperature. If these measures are inadequate, calcium-channel blockers are the most widely used (nifedipine 30 mg up to 90 mg daily. Alternatively, sympatholytic agent (prazosin, angiotensin II -receptor type I antagonist (losartan, selective sertonin-reuptake inhibitor (fluoxetine may be useful. In the severe cases the role of

  7. Attention to local and global levels of hierarchical Navon figures affects rapid scene categorization.

    Brand, John; Johnson, Aaron P

    2014-01-01

    In four experiments, we investigated how attention to local and global levels of hierarchical Navon figures affected the selection of diagnostic spatial scale information used in scene categorization. We explored this issue by asking observers to classify hybrid images (i.e., images that contain low spatial frequency (LSF) content of one image, and high spatial frequency (HSF) content from a second image) immediately following global and local Navon tasks. Hybrid images can be classified according to either their LSF, or HSF content; thus, making them ideal for investigating diagnostic spatial scale preference. Although observers were sensitive to both spatial scales (Experiment 1), they overwhelmingly preferred to classify hybrids based on LSF content (Experiment 2). In Experiment 3, we demonstrated that LSF based hybrid categorization was faster following global Navon tasks, suggesting that LSF processing associated with global Navon tasks primed the selection of LSFs in hybrid images. In Experiment 4, replicating Experiment 3 but suppressing the LSF information in Navon letters by contrast balancing the stimuli examined this hypothesis. Similar to Experiment 3, observers preferred to classify hybrids based on LSF content; however and in contrast, LSF based hybrid categorization was slower following global than local Navon tasks.

A wide array of pharmacologic agents has been used for this therapy. None of them have clear proven therapeutic value in a trial setting. Most of the practice involved with pharmacotherapy for no reflow is based on operator experience and thus anecdote.      Pharmacologic agents are administered into the affected vascular bed through a distal catheter. When drugs are given through a guiding catheter, they will preferentially flow to areas that have preserved run off. For example, when there is slow flow in the distal circumflex artery injection into a left system guide catheter will result in the injected agent going to the contralateral vessel and never reaching the target vascular bed. Thus an infusion catheter or an over the wire balloon catheter must be delivered distal to the target lesion in the distal vasculature and injections given through this catheter.1      Intracoronary nitroglycerin has been the traditional first line agent for this therapy. However the response of the no reflow phenomenon to nitroglycerin has been poor and it is not realistic to recommend this as a first line

  10. Global temperature definition affects achievement of long-term climate goals

    Richardson, Mark; Cowtan, Kevin; Millar, Richard J.

    2018-05-01

    The Paris Agreement on climate change aims to limit ‘global average temperature’ rise to ‘well below 2 °C’ but reported temperature depends on choices about how to blend air and water temperature data, handle changes in sea ice and account for regions with missing data. Here we use CMIP5 climate model simulations to estimate how these choices affect reported warming and carbon budgets consistent with the Paris Agreement. By the 2090s, under a low-emissions scenario, modelled global near-surface air temperature rise is 15% higher (5%–95% range 6%–21%) than that estimated by an approach similar to the HadCRUT4 observational record. The difference reduces to 8% with global data coverage, or 4% with additional removal of a bias associated with changing sea-ice cover. Comparison of observational datasets with different data sources or infilling techniques supports our model results regarding incomplete coverage. From high-emission simulations, we find that a HadCRUT4 like definition means higher carbon budgets and later exceedance of temperature thresholds, relative to global near-surface air temperature. 2 °C warming is delayed by seven years on average, to 2048 (2035–2060), and CO2 emissions budget for a >50% chance of <2 °C warming increases by 67 GtC (246 GtCO2).

  12. Phenomenon detection device

    Suzuki, Yasuo.

    1994-01-01

    Detection signals for a specific phenomenon outputted from any of detectors are distributed by way of half mirrors and inputted to a logic discrimination circuit by way of a photoelectric convertor. The photoelectric convertor detects the quantity of light corresponding to the optical signals from more than two detectors which detected the phenomenon, and outputs detection signals to the logic discrimination circuit. If the phenomenon is detected, since both inputs turn ON in the logic discrimination circuit in accordance with the predetermined logical sum, the occurrence of a specific phenomenon is detected. Thus, an optical system substantially comprises half mirrors, reflection mirrors and photoelectric convertor in combination provides a logic circuit. Since the circuit which transmits signals of the detectors is constituted with an optical system using the half mirrors, the number of parts constituting the logic circuit can greatly be saved. In addition, since the optical system comprises mirrors or half mirrors which have been used so far, they can be used, once assembled, quasipermanently, and the reliability can be enhanced greatly.

    Biological communities populating the Mediterranean Sea, which is situated at the northern boundary of the subtropics, are often claimed to be particularly affected by global warming. This is indicated, for instance, by the introduction of (sub)tropical species of fish or invertebrates that can displace local species. This raises the question of whether microbial communities are similarly affected, especially in the Levantine basin where sea surface temperatures have significantly risen over the last 25 years (0.50 ± 0.11 °C in average per decade, P Lions and by clade III and groups genetically related to clades WPC1 and VI in the rest of the Mediterranean Sea. In contrast, only a few sequences of clade II, a group typical of warm waters, were observed. These data indicate that local cyanobacterial populations have not yet been displaced by their (sub)tropical counterparts.

  15. Affective, parochial or innovative? Aleppo traders on the margin of global capitalism

    Annika Rabo

    2012-02-01

    Full Text Available This article scrutinizes three different, and possible, ways to depict traders in contemporary Aleppo. They can be seen as sharing a distinct culture, as representatives of the petite bourgeoisie, or as examples of entrepreneurs. While all these approaches tell us something about the Aleppo traders, these approaches have great limitations, not least since the latter two – each in its own way – are utility-oriented. It is, I will rather argue, important to analyze Aleppo traders as affective, parochial and innovative, at the same time. Although Aleppo traders find themselves on the margins of global capitalism, they can, in fact, be studied in order to understand salient features of the contemporary world. We have a new affective economy where personalities, emotions and sensibilities are put on the market. The article is based on material collected during social anthropological fieldwork in Aleppo between 1997 and 2003, but mainly carried out in 1998-1999.

  16. Global warming may disproportionately affect larger adults in a predatory coral reef fish

    Messmer, Vanessa

    2016-11-03

    Global warming is expected to reduce body sizes of ectothermic animals. Although the underlying mechanisms of size reductions remain poorly understood, effects appear stronger at latitudinal extremes (poles and tropics) and in aquatic rather than terrestrial systems. To shed light on this phenomenon, we examined the size dependence of critical thermal maxima (CTmax) and aerobic metabolism in a commercially important tropical reef fish, the leopard coral grouper (Plectropomus leopardus) following acclimation to current-day (28.5 °C) vs. projected end-of-century (33 °C) summer temperatures for the northern Great Barrier Reef (GBR). CTmax declined from 38.3 to 37.5 °C with increasing body mass in adult fish (0.45-2.82 kg), indicating that larger individuals are more thermally sensitive than smaller conspecifics. This may be explained by a restricted capacity for large fish to increase mass-specific maximum metabolic rate (MMR) at 33 °C compared with 28.5 °C. Indeed, temperature influenced the relationship between metabolism and body mass (0.02-2.38 kg), whereby the scaling exponent for MMR increased from 0.74 ± 0.02 at 28.5 °C to 0.79 ± 0.01 at 33 °C, and the corresponding exponents for standard metabolic rate (SMR) were 0.75 ± 0.04 and 0.80 ± 0.03. The increase in metabolic scaling exponents at higher temperatures suggests that energy budgets may be disproportionately impacted in larger fish and contribute to reduced maximum adult size. Such climate-induced reductions in body size would have important ramifications for fisheries productivity, but are also likely to have knock-on effects for trophodynamics and functioning of ecosystems.

    massive means of communication. It is necessary to wonder if this globalization phenomenon is something originated in this concrete historical moment or it is a tendency that has antecedents in the past. Then the purpose of this work is to analize How in the course of the humanity has existed an expansion of certain languages related with political and economical factors of the world supremacy. It is carried out a historical review that compaises since the Greek world until the XX century. Besides it is offered a panorama of the development of the linguistic, philosophical and pedagogical theories in the different stages of the history. It is showed that since Hellenic civilization until the present time processes of universalization of the language of the dominant powers have been developed in some atages in a total way an in others, partially according to the well-known world in those periods. It is concluded that the globalization of the language is not a current phenomenon, but historical, that the two philosophical positions (materialism and idealism have impacted in the linguistic and pedagogical theories present in all studied historiacal period and It is remarkable the postmodernist position of the communicative focus of the teaching English and its first world tendency

    This monograph investigates violations of statistical stability of physical events, variables, and processes and develops a new physical-mathematical theory taking into consideration such violations – the theory of hyper-random phenomena. There are five parts. The first describes the phenomenon of statistical stability and its features, and develops methods for detecting violations of statistical stability, in particular when data is limited. The second part presents several examples of real processes of different physical nature and demonstrates the violation of statistical stability over broad observation intervals. The third part outlines the mathematical foundations of the theory of hyper-random phenomena, while the fourth develops the foundations of the mathematical analysis of divergent and many-valued functions. The fifth part contains theoretical and experimental studies of statistical laws where there is violation of statistical stability. The monograph should be of particular interest to engineers...

  2. Exploring the influence of the Global Fund and the GAVI Alliance on health systems in conflict-affected countries.

    Patel, Preeti; Cummings, Rachael; Roberts, Bayard

    2015-01-01

    Global Health Initiatives (GHIs) respond to high-impact communicable diseases in resource-poor countries, including health systems support, and are major actors in global health. GHIs could play an important role in countries affected by armed conflict given these countries commonly have weak health systems and a high burden of communicable disease. The aim of this study is to explore the influence of two leading GHIs, the Global Fund and the GAVI Alliance, on the health systems of conflict-affected countries. This study used an analytical review approach to identify evidence on the role of the Global Fund and the GAVI Alliance with regards to health systems support to 19 conflict-affected countries. Primary and secondary published and grey literature were used, including country evaluations from the Global Fund and the GAVI Alliance. The WHO heath systems building blocks framework was used for the analysis. There is a limited evidence-base on the influence of GHIs on health systems of conflict-affected countries. The findings suggest that GHIs are increasingly investing in conflict-affected countries which has helped to rapidly scale up health services, strengthen human resources, improve procurement, and develop guidelines and protocols. Negative influences include distorting priorities within the health system, inequitable financing of disease-specific services over other health services, diverting staff away from more essential health care services, inadequate attention to capacity building, burdensome reporting requirements, and limited flexibility and responsiveness to the contextual challenges of conflict-affected countries. There is some evidence of increasing engagement of the Global Fund and the GAVI Alliance with health systems in conflict-affected countries, but this engagement should be supported by more context-specific policies and approaches.

  3. The Phenomenon of Dental Fear

    Moore, Rod

    Odontophobia is a rather unique phobia with special psychosomatic components that impact on the dental health of odontophobic persons. It also has psychosocial components largely as a result of destruction of the teeth and subsequent embarrassment that can affect a person and cause a vicious cycle...... of dental fear (see fig. 1). The phenomenon is facilitated by misunderstandings and myths generated by both patients and dentists (see table 1 for examples). The most common reasons given in the literature for such strong fears of dental treatment are: 1) bad experiences in childhood for 85% of cases, 2......) feeling of powerlessness and lack of control over personal emotional reactions and over the social situation in the dental chair, 3) social learning processes in which the image of the dentist is cast in a negative light by the mass media or by the person's relatives or friends and 4) that the person has...

    Biological communities populating the Mediterranean Sea, which is situated at the northern boundary of the subtropics, are often claimed to be particularly affected by global warming. This is indicated, for instance, by the introduction of (sub)tropical species of fish or invertebrates that can displace local species. This raises the question of whether microbial communities are similarly affected, especially in the Levantine basin where sea surface temperatures have risen in recent years. In this paper, the genetic diversity of the two most abundant members of the phytoplankton community, the picocyanobacteria Prochlorococcus and Synechococcus, was examined on a transect from the South coast of France to Cyprus in the summer of 2008 (BOUM cruise). Diversity was studied using dot blot hybridization with clade-specific 16S rRNA oligonucleotide probes and clone libraries of the 16S-23S ribosomal DNA Internal Transcribed Spacer (ITS) region. Data were compared with those obtained during the PROSOPE cruise held almost a decade earlier, with a focus on the abundance of clades that may constitute bioindicators of warm waters. During both cruises, the dominant Prochlorococcus clade in the upper mixed layer at all stations was HLI, a clade typical of temperate waters, whereas the HLII clade, the dominant group in (sub)tropical waters, was only present at very low concentrations.

In contrast, only a few sequences of clade II, a group typical of warm waters, were observed. These data indicate that local cyanobacterial populations have not yet been displaced by their (sub)tropical counterparts. This is discussed in the context of the low phosphorus concentrations found in surface waters in the eastern Mediterranean basin, as this may constitute a barrier to

  6. The crossed phrenic phenomenon.

    Ghali, Michael George Zaki

    2017-06-01

    The cervical spine is the most common site of traumatic vertebral column injuries. Respiratory insufficiency constitutes a significant proportion of the morbidity burden and is the most common cause of mortality in these patients. In seeking to enhance our capacity to treat specifically the respiratory dysfunction following spinal cord injury, investigators have studied the "crossed phrenic phenomenon", wherein contraction of a hemidiaphragm paralyzed by a complete hemisection of the ipsilateral cervical spinal cord above the phrenic nucleus can be induced by respiratory stressors and recovers spontaneously over time. Strengthening of latent contralateral projections to the phrenic nucleus and sprouting of new descending axons have been proposed as mechanisms contributing to the observed recovery. We have recently demonstrated recovery of spontaneous crossed phrenic activity occurring over minutes to hours in C 1 -hemisected unanesthetized decerebrate rats. The specific neurochemical and molecular pathways underlying crossed phrenic activity following injury require further clarification. A thorough understanding of these is necessary in order to develop targeted therapies for respiratory neurorehabilitation following spinal trauma. Animal studies provide preliminary evidence for the utility of neuropharmacological manipulation of serotonergic and adenosinergic pathways, nerve grafts, olfactory ensheathing cells, intraspinal microstimulation and a possible role for dorsal rhizotomy in recovering phrenic activity following spinal cord injury.

  8. The tsunami phenomenon

    Röbke, B. R.; Vött, A.

    2017-12-01

    With human activity increasingly concentrating on coasts, tsunamis (from Japanese tsu = harbour, nami = wave) are a major natural hazard to today's society. Stimulated by disastrous tsunami impacts in recent years, for instance in south-east Asia (2004) or in Japan (2011), tsunami science has significantly flourished, which has brought great advances in hazard assessment and mitigation plans. Based on tsunami research of the last decades, this paper provides a thorough treatise on the tsunami phenomenon from a geoscientific point of view. Starting with the wave features, tsunamis are introduced as long shallow water waves or wave trains crossing entire oceans without major energy loss. At the coast, tsunamis typically show wave shoaling, funnelling and resonance effects as well as a significant run-up and backflow. Tsunami waves are caused by a sudden displacement of the water column due to a number of various trigger mechanisms. Such are earthquakes as the main trigger, submarine and subaerial mass wastings, volcanic activity, atmospheric disturbances (meteotsunamis) and cosmic impacts, as is demonstrated by giving corresponding examples from the past. Tsunamis are known to have a significant sedimentary and geomorphological off- and onshore response. So-called tsunamites form allochthonous high-energy deposits that are left at the coast during tsunami landfall. Tsunami deposits show typical sedimentary features, as basal erosional unconformities, fining-upward and -landward, a high content of marine fossils, rip-up clasts from underlying units and mud caps, all reflecting the hydrodynamic processes during inundation. The on- and offshore behaviour of tsunamis and related sedimentary processes can be simulated using hydro- and morphodynamic numerical models. The paper provides an overview of the basic tsunami modelling techniques, including discretisation, guidelines for appropriate temporal and spatial resolution as well as the nesting method. Furthermore, the

  13. Globalization challenges in a globalized world

    Dr.Sc. Gjon Boriçi

    2016-01-01

    Full Text Available Globalization is an ongoing phenomenon trying to redefine the economic, social, cultural and political dynamics of contemporary societies. The communication among countries and not only them, has been increased expanding political ties, making possible greater economic integration and wider cultural relations combined with augmented global wealth across the world. But, the process of globalization is in wider terms considered a beneficial one, but also viewed by some countries as a menace to national sovereignty and national culture. This paper tries to explain the obstacles to the process of globalization and its attendant benefits. Although globalization has arisen as a result of a more stable world, the factors that had contributed to its rise also help the factions interested to bring destabilization. In an academic approach in this article, between the research and comparative methods, I have been trying to get the maxims between economy, politics and diplomacy in their efforts of affecting the global era.

  17. Disciplinary reporting affects the interpretation of climate change impacts in global oceans.

    Hauser, Donna D W; Tobin, Elizabeth D; Feifel, Kirsten M; Shah, Vega; Pietri, Diana M

    2016-01-01

    Climate change is affecting marine ecosystems, but different investigative approaches in physical, chemical, and biological disciplines may influence interpretations of climate-driven changes in the ocean. Here, we review the ocean change literature from 2007 to 2012 based on 461 of the most highly cited studies in physical and chemical oceanography and three biological subdisciplines. Using highly cited studies, we focus on research that has shaped recent discourse on climate-driven ocean change. Our review identified significant differences in spatial and temporal scales of investigation among disciplines. Physical/chemical studies had a median duration of 29 years (n = 150) and covered the greatest study areas (median 1.41 × 10(7) km(2) , n = 148). Few biological studies were conducted over similar spatial and temporal scales (median 8 years, n = 215; median 302 km(2) , n = 196), suggesting a more limited ability to separate climate-related responses from natural variability. We linked physical/chemical and biological disciplines by tracking studies examining biological responses to changing ocean conditions. Of the 545 biological responses recorded, a single physical or chemical stressor was usually implicated as the cause (59%), with temperature as the most common primary stressor (44%). The most frequently studied biological responses were changes in physiology (31%) and population abundance (30%). Differences in disciplinary studies, as identified in this review, can ultimately influence how researchers interpret climate-related impacts in marine systems. We identified research gaps and the need for more discourse in (1) the Indian and other Southern Hemisphere ocean basins; (2) research themes such as archaea, bacteria, viruses, mangroves, turtles, and ocean acidification; (3) physical and chemical stressors such as dissolved oxygen, salinity, and upwelling; and (4) adaptive responses of marine organisms to climate-driven ocean change. Our findings reveal

  19. How Will Global Environmental Changes Affect the Growth of Alien Plants?

    Jujie Jia

    2016-11-01

    Full Text Available Global environmental changes can create novel habitats, promoting the growth of alien plants that often exhibit broad environmental tolerance and high phenotypic plasticity. However, the mechanisms underlying these growth promotory effects are unknown at present. Here, we conducted a phylogenetically controlled meta-analysis using data from 111 published studies encompassing the responses of 129 alien plants to global warming, increased precipitation, N deposition, and CO2 enrichment. We compared the differences in the responses of alien plants to the four global environmental change factors across six categories of functional traits between woody and non-woody life forms as well as C3 and C4 photosynthetic pathways. Our results showed that all four global change factors promote alien plant growth. Warming had a more positive effect on C4 than C3 plants. Although the effects of the four factors on the functional traits of alien plants were variable, plant growth was mainly promoted via an increase in growth rate and size. Our data suggest that potential future global environmental changes could further facilitate alien plant growth.

  1. Distancing from experienced self: how global-versus-local perception affects estimation of psychological distance.

    Liberman, Nira; Förster, Jens

    2009-08-01

    In 4 studies, the authors examined the prediction derived from construal level theory (CLT) that higher level of perceptual construal would enhance estimated egocentric psychological distance. The authors primed participants with global perception, local perception, or both (the control condition). Relative to the control condition, global processing made participants estimate larger psychological distances in time (Study 1), space (Study 2), social distance (Study 3), and hypotheticality (Study 4). Local processing had the opposite effect. Consistent with CLT, all studies show that the effect of global-versus-local processing did emerge when participants estimated egocentric distances, which are distances from the experienced self in the here and now, but did not emerge with temporal distances not from now (Study 1), spatial distances not from here (Study 2), social distances not from the self (Study 3), or hypothetical events that did not involve altering an experienced reality (Study 4).

  3. Susceptibility of South Korea to Extremes Affecting the Global Food System

    Chon, So Young; Puma, Michael J.

    2015-01-01

    Food security in South Korea is tightly linked to the global food system. The country's production of major grains declined from 5.8 million metric tons (mmt) in 1998 to 4.8 mmt in 2014, which caused the country's grain self suciency to decline from 31.4% to 24%. This decline is a consequence of several factors including reductions in domestic agricultural land, governmental policies supporting industry over agriculture, and a push towards trade liberalization. South Korea's self suciency is now one of the lowest among Organisation for Economic Co-operation and Development (OECD) countries, leaving it vulnerable to disruptions in the global food system.

    2018-05-15

    Globally, latent heating associated with a change in precipitation is balanced by changes to atmospheric radiative cooling and sensible heat fluxes. Both components can be altered by climate forcing mechanisms and through climate feedbacks, but the impacts of climate forcing and feedbacks on sensible heat fluxes have received much less attention. Here we show, using a range of climate modelling results, that changes in sensible heat are the dominant contributor to the present global-mean precipitation change since preindustrial time, because the radiative impact of forcings and feedbacks approximately compensate. The model results show a dissimilar influence on sensible heat and precipitation from various drivers of climate change. Due to its strong atmospheric absorption, black carbon is found to influence the sensible heat very differently compared to other aerosols and greenhouse gases. Our results indicate that this is likely caused by differences in the impact on the lower tropospheric stability.

Based on the World Economic Forum (WEF report on global risks 2015-2017, the impact of global risks on the social and economic development of countries is examined. Economic, social, environmental, geopolitical, technological risks are analyzed in a coordinated fashion. The article notes that the main risks are in the field of environment and ecology. Anthropogenic pressure amplification, scientific and technological advance have an influence on the natural environment. The risks of infrastructure and environmental damage in danger zone are increased because of the growth of the frequency of extreme weather events. The measures for the protection of the environment are examined. The unilateral approach to solving international issues, instead of the collective efforts of the international community; the deployment of weapons of mass destruction (nuclear, chemical, biological and technologies for the production of radioactive materials; escalation of economic and resource nationalization (the desire of States to expropriate or restrict the export of important for the world economy of resources, etc. promote the increasing geopolitical risks.Economic risks include the risk in terms of their likelihood their impact on the macroeconomic, as from the financial systems and infrastructure to price volatility and regulatory issues. Social risks are the risks relating to instability of population dynamics, social crises and human survival.Technological risks include such problems as software defects, failure of important information systems, upon which today industrial production is depended, the services and communications sector; the escalation of large-scale cyber-attacks; theft of electronic information and the illegal usage of personal data. The trends that can intensify the global risks or to change the correlation between them are analyzed in this article.

  11. Simulative Global Warming Negatively Affects Cotton Fiber Length through Shortening Fiber Rapid Elongation Duration.

    Global warming could possibly increase the air temperature by 1.8-4.0 °C in the coming decade. Cotton fiber is an essential raw material for the textile industry. Fiber length, which was found negatively related to the excessively high temperature, determines yarn quality to a great extent. To investigate the effects of global warming on cotton fiber length and its mechaism, cottons grown in artificially elevated temperature (34.6/30.5 °C, T day /T night ) and ambient temperature (31.6/27.3 °C) regions have been investigated. Becaused of the high sensitivities of enzymes V-ATPase, PEPC, and genes GhXTH1 and GhXTH2 during fiber elongation when responding to high temperature stress, the fiber rapid elongation duration (FRED) has been shortened, which led to a significant suppression on final fiber length. Through comprehensive analysis, T night had a great influence on fiber elongation, which means T n could be deemed as an ideal index for forecasting the degree of high temperature stress would happen to cotton fiber property in future. Therefore, we speculate the global warming would bring unfavorable effects on cotton fiber length, which needs to take actions in advance for minimizing the loss in cotton production.

    The aim of this review was to evaluate the balling phenomenon which occurs typically in Selective Laser Sintering (SLS). The balling phenomenon is a typical SLS defect, and observed in laser sintered powder, significantly reduces the quality of SLS, and hinders the further development of SLS Technology. Electronic database searches were performed using Google Scholar. The keywords "laser sintering, selective laser sintering, direct metal laser melting, and balling phenomenon" were searched in title/abstract of publications, limited to December 31, 2016. The inclusion criteria were SLS, balling phenomenon, some alloys (such as Cr-Co, iron, stainless steel, and Cu-based alloys) mechanical properties, microstructure and bond strength between metal-ceramic crown, laboratory studies, full text, and in English language. A total of 100 articles were found the initial search and yielded a total of 50 studies, 30 of which did not fulfill the inclusion criteria and were therefore excluded. In addition, 20 studies were found by screening the reference list of all included publications. Finally, 40 studies were selected for this review. The method in question is regulated by powder material characteristics and the conditions of laser processing. The procedure of formation, affecting factors, and the mechanism of the balling effect are very complex.

  13. Global drought and severe drought-affected populations in 1.5 and 2 °C warmer worlds

    Liu, Wenbin; Sun, Fubao; Lim, Wee Ho; Zhang, Jie; Wang, Hong; Shiogama, Hideo; Zhang, Yuqing

    2018-03-01

    The 2015 Paris Agreement proposed a more ambitious climate change mitigation target on limiting global warming to 1.5 °C instead of 2 °C above preindustrial levels. Scientific investigations on environmental risks associated with these warming targets are necessary to inform climate policymaking. Based on the Coupled Model Intercomparison Project phase 5 (CMIP5) climate models, we present the first risk-based assessment of changes in global drought and the impact of severe drought on populations from additional 1.5 and 2 °C warming conditions. Our results highlight the risk of drought on a global scale and in several hotspot regions such as the Amazon, northeastern Brazil, southern Africa and Central Europe at both 1.5 and 2 °C global warming relative to the historical period, showing increases in drought durations from 2.9 to 3.2 months. Correspondingly, more total and urban populations would be exposed to severe droughts globally (+132.5 ± 216.2 million and +194.5 ± 276.5 million total population and +350.2 ± 158.8 million and +410.7 ± 213.5 million urban populations in 1.5 and 2 °C warmer worlds) and regionally (e.g., East Africa, West Africa and South Asia). Less rural populations (-217.7 ± 79.2 million and -216.2 ± 82.4 million rural populations in 1.5 and 2 °C warmer worlds) would be exposed to severe drought globally under climate warming, population growth and especially the urbanization-induced population migration. By keeping global warming at 1.5 °C above the preindustrial levels instead of 2 °C, there is a decrease in drought risks (i.e., less drought duration, less drought intensity and severity but relatively more frequent drought) and the affected total, urban and rural populations would decrease globally and in most regions. While challenging for both East Africa and South Asia, the benefits of limiting warming to below 1.5 °C in terms of global drought risk and impact reduction are significant.

  16. Surgical Care Required for Populations Affected by Climate-related Natural Disasters: A Global Estimation.

    Lee, Eugenia E; Stewart, Barclay; Zha, Yuanting A; Groen, Thomas A; Burkle, Frederick M; Kushner, Adam L

    2016-08-10

    Climate extremes will increase the frequency and severity of natural disasters worldwide.  Climate-related natural disasters were anticipated to affect 375 million people in 2015, more than 50% greater than the yearly average in the previous decade. To inform surgical assistance preparedness, we estimated the number of surgical procedures needed.   The numbers of people affected by climate-related disasters from 2004 to 2014 were obtained from the Centre for Research of the Epidemiology of Disasters database. Using 5,000 procedures per 100,000 persons as the minimum, baseline estimates were calculated. A linear regression of the number of surgical procedures performed annually and the estimated number of surgical procedures required for climate-related natural disasters was performed. Approximately 140 million people were affected by climate-related natural disasters annually requiring 7.0 million surgical procedures. The greatest need for surgical care was in the People's Republic of China, India, and the Philippines. Linear regression demonstrated a poor relationship between national surgical capacity and estimated need for surgical care resulting from natural disaster, but countries with the least surgical capacity will have the greatest need for surgical care for persons affected by climate-related natural disasters. As climate extremes increase the frequency and severity of natural disasters, millions will need surgical care beyond baseline needs. Countries with insufficient surgical capacity will have the most need for surgical care for persons affected by climate-related natural disasters. Estimates of surgical are particularly important for countries least equipped to meet surgical care demands given critical human and physical resource deficiencies.

  17. Will global warming affect soil-to-plant transfer of radionuclides?

    Dowdall, M.; Standring, W.; Shaw, G.; Strand, P.

    2008-01-01

    Recent assessments of global climate/environmental change are reaching a consensus that global climate change is occurring but there is significant uncertainty over the likely magnitude of this change and its impacts. There is little doubt that all aspects of the natural environment will be impacted to some degree. Soil-to-plant transfer of radionuclides has long been a significant topic in radioecology, both for the protection of humans and the environment from the effects of ionising radiation. Even after five decades of research considerable uncertainty exists as to the interplay of key environmental processes in controlling soil-plant transfer. As many of these processes are, to a lesser or greater extent, climate-dependent, it can be argued that climate/environmental change will impact soil-to-plant transfer of radionuclides and subsequent transfers in specific environments. This discussion attempts to highlight the possible role of climatic and climate-dependent variables in soil-to-plant transfer processes within the overall predictions of climate/environmental change. The work is speculative, and intended to stimulate debate on a theme that radioecology has either ignored or avoided in recent years

  18. Historic and future increase in the global land area affected by monthly heat extremes

    Coumou, Dim; Robinson, Alexander

    2013-01-01

    Climatic warming of about 0.5 ° C in the global mean since the 1970s has strongly increased the occurrence-probability of heat extremes on monthly to seasonal time scales. For the 21st century, climate models predict more substantial warming. Here we show that the multi-model mean of the CMIP5 (Coupled Model Intercomparison Project) climate models accurately reproduces the evolution over time and spatial patterns of the historically observed increase in monthly heat extremes. For the near-term (i.e., by 2040), the models predict a robust, several-fold increase in the frequency of such heat extremes, irrespective of the emission scenario. However, mitigation can strongly reduce the number of heat extremes by the second half of the 21st century. Unmitigated climate change causes most (>50%) continental regions to move to a new climatic regime with the coldest summer months by the end of the century substantially hotter than the hottest experienced today. We show that the land fraction experiencing extreme heat as a function of global mean temperature follows a simple cumulative distribution function, which depends only on natural variability and the level of spatial heterogeneity in the warming.

  19. A global analysis of fine root production as affected by soil nitrogen and phosphorus.

    Yuan, Z Y; Chen, Han Y H

    2012-09-22

    Fine root production is the largest component of belowground production and plays substantial roles in the biogeochemical cycles of terrestrial ecosystems. The increasing availability of nitrogen (N) and phosphorus (P) due to human activities is expected to increase aboveground net primary production (ANNP), but the response of fine root production to N and P remains unclear. If roots respond to nutrients as ANNP, fine root production is anticipated to increase with increasing soil N and P. Here, by synthesizing data along the nutrient gradient from 410 natural habitats and from 469 N and/or P addition experiments, we showed that fine root production increased in terrestrial ecosystems with an average increase along the natural N gradient of up to 0.5 per cent with increasing soil N. Fine root production also increased with soil P in natural conditions, particularly at P production increased by a global average of 27, 21 and 40 per cent, respectively. However, its responses differed among ecosystems and soil types. The global average increases in fine root production are lower than those of ANNP, indicating that above- and belowground counterparts are coupled, but production allocation shifts more to aboveground with higher soil nutrients. Our results suggest that the increasing fertilizer use and combined N deposition at present and in the future will stimulate fine root production, together with ANPP, probably providing a significant influence on atmospheric CO(2) emissions.

    Globalization is often referred to as external to education - a state of affair facing the modern curriculum with numerous challenges. In this paper it is examined as internal to curriculum; analysed as a problematization in a Foucaultian sense. That is, as a complex of attentions, worries, ways...... of reasoning, producing curricular variables. The analysis is made through an example of early childhood curriculum in Danish Pre-school, and the way the curricular variable of the pre-school child comes into being through globalization as a problematization, carried forth by the comparative practices of PISA...

Some economists have argued that globalization has arrived and that the world is “flat†. While the geographic scope of markets has increased, the author argues that new patterns of trade and finance are a result of the discrepancies between “old†countries and “new†. As the differences are gradually wiped out, particularly if knowledge and technology spread worldwide, the t...

  2. Koebner Phenomenon and Mycosis Fungoides

    Eve Lebas

    2015-10-01

    Full Text Available Mycosis fungoides (MF is the most frequent type of primary cutaneous T-cell/NK-cell lymphoma. The Koebner phenomenon is defined as the appearance of cutaneous lesions on previously noninvolved skin following trauma and is observed in a series of cutaneous diseases including psoriasis, lichen planus, viral warts, molluscum contagiosum, etc. In this case report, 3 patients with longstanding MF are presented, the 1st with the appearance of a circumscribed early-stage type MF lesion rapidly following a surgical excision of an infundibular cyst, the 2nd with the appearance of a unique unilateral palmar tumoral MF lesion at the pressure site of a crutch, and the 3rd presented localized MF early stage lesions at the friction site of a belt. This report suggests that some MF patients may experience Koebner phenomenon-induced MF lesions and that MF should be added to the long list of skin diseases potentially exhibiting the Koebner phenomenon.

  3. The factors affecting Nigeria's success toward implementation of global public health priorities.

    Echebiri, Vitalis C

    2015-06-01

    This paper examines the challenges facing the Nigerian government toward the implementation of global public health priories. The Nigerian government recognizes the need to implement these priorities by putting in place the necessary policy framework, but political instability, poor infrastructural development and inadequate funding have remained barriers toward the achievement of success in implementing these priorities. The rest of the paper elucidates the fact that despite leadership and influence from the World Health Organization and other United Nations agencies, and some responses from the Nigerian government, tackling these public health problems requires much more fundamental reform to primary health services and a reduction in poverty. Although the government has shown enough political will to tackle these problems, it is expected that a better result will be achieved through injecting more funds into the Nigerian health sector, and deploying astute health administrators to manage the sector rather than pure health professionals without managerial acumen. © The Author(s) 2014.

  4. Black Carbon Absorption at the Global Scale Is Affected by Particle-Scale Diversity in Composition

    Fierce, Laura; Bond, Tami C.; Bauer, Susanne E.; Mena, Francisco; Riemer, Nicole

    2016-01-01

    Atmospheric black carbon (BC) exerts a strong, but uncertain, warming effect on the climate. BC that is coated with non-absorbing material absorbs more strongly than the same amount of BC in an uncoated particle, but the magnitude of this absorption enhancement (E(sub abs)) is not well constrained. Modelling studies and laboratory measurements have found stronger absorption enhancement than has been observed in the atmosphere. Here, using a particle-resolved aerosol model to simulate diverse BC populations, we show that absorption is overestimated by as much as a factor of two if diversity is neglected and population-averaged composition is assumed across all BC-containing particles. If, instead, composition diversity is resolved, we find E(sub abs) = 1 - 1.5 at low relative humidity, consistent with ambient observations. This study offers not only an explanation for the discrepancy between modelled and observed absorption enhancement, but also demonstrates how particle-scale simulations can be used to develop relationships for global-scale models.

  5. Effect of Temperature Rising on the Stygobitic Crustacean Species Diacyclops belgicus: Does Global Warming Affect Groundwater Populations?

    Tiziana Di Lorenzo

    2017-12-01

    Full Text Available The average global temperature is predicted to increase by 3 °C by the end of this century due to human-induced climate change. The overall metabolism of the aquatic biota will be directly affected by rising temperatures and associated changes. Since thermal stability is a characteristic of groundwater ecosystems, global warming is expected to have a profound effect on the groundwater fauna. The prediction that stygobitic (obligate groundwater dweller species are vulnerable to climate change includes assumptions about metabolic effects that can only be tested by comparisons across a thermal gradient. To this end, we investigated the effects of two different thermal regimes on the metabolism of the stygobitic copepod species Diacyclops belgicus (Kiefer, 1936. We measured the individual-based oxygen consumption of this species as a proxy of possible metabolic reactions to temperature rising from 14 to 17 °C. We used a sealed glass microplate equipped with planar oxygen sensor spots with optical isolation glued onto the bottom of 80-μL wells integrated with a 24-channel fluorescence-based respirometry system. The tests have provided controversial results according to which the D. belgicus populations should be prudently considered at risk under a global warming scenario.

  6. Coal lumps vs. electrons: How do Chinese bulk energy transport decisions affect the global steam coal market?

    Paulus, Moritz; Trüby, Johannes

    2011-01-01

    This paper demonstrates the ways in which different Chinese bulk energy transport strategies affect the future steam coal market in China and in the rest of the world. An increase in Chinese demand for steam coal will lead to a growing need for additional domestic infrastructure as production hubs and demand centers are spatially separated, and domestic transport costs could influence the future Chinese steam coal supply mix. If domestic transport capacity is available only at elevated costs, Chinese power generators could turn to the global trade markets and further increase steam coal imports. Increased Chinese imports could then yield significant changes in steam coal market economics on a global scale. This effect is analyzed in China, where coal is mainly transported by railway, and in another setting where coal energy is transported as electricity. For this purpose, a spatial equilibrium model for the global steam coal market has been developed. One major finding is that if coal is converted into electricity early in the supply chain, worldwide marginal costs of supply are lower than if coal is transported via railway. Furthermore, China's dependence on international imports is significantly reduced in this context. Allocation of welfare changes particularly in favor of Chinese consumers while rents of international producers decrease.

  7. Global Epidemiology of HIV Infection and Related Syndemics Affecting Transgender People

    Scheim, Ayden; Xavier, Jessica; Reisner, Sari; Baral, Stefan

    2016-01-01

    Introduction: Transgender populations have been underrepresented in HIV epidemiologic studies and consequently in HIV prevention, care, and treatment programs. Since 2012, there has been a dramatic increase in research focused on transgender people. Studies highlight the burden of HIV and risk determinants, including intersecting stigmas, as drivers of syndemics among transgender populations. This review synthesizes the most recent global epidemiology of HIV infection and describes current gaps in research and interventions to inform prioritization of HIV research for transgender populations. Methods: A systematic review was conducted of the medical literature published between January 1, 2012 and November 30, 2015. The data focused on HIV prevalence, determinants of risk, and syndemics among transgender populations. Results: Estimates varied dramatically by location and subpopulation. Transfeminine individuals have some of the highest concentrated HIV epidemics in the world with laboratory-confirmed prevalence up to 40%. Data were sparse among trans masculine individuals; however, they suggest potential increased risk for trans masculine men who have sex with men (MSM). No prevalence data were available for transgender people across Sub-Saharan Africa or Eastern Europe/Central Asia. Emerging data consistently support the association of syndemic conditions with HIV risk in transgender populations. Discussion: Addressing syndemic conditions and gender-specific challenges is critical to ensure engagement and retention in HIV prevention by transgender populations. Future research should prioritize: filling knowledge gaps in HIV epidemiology; elucidating how stigma shapes syndemic factors to produce HIV and other deleterious effects on transgender health; and understanding how to effectively implement HIV interventions for transgender people.

  8. Factors affecting sustainable iodine deficiency elimination in Pakistan: A global perspective

    Rehman Mehmood Khattak

    2017-06-01

    Full Text Available Iodine deficiency remains a considerable challenge worldwide, even after decades of efforts to address the problem. The aim of this review is to present the current situation in historically iodine-deficient Pakistan regarding iodine nutritional status and place it in a global perspective. We collected relevant articles from online bibliographic databases and websites of concerned organizations that addressed prevalence of goiter/iodine deficiency and barriers to sustainable control. We divided the studies into pre- and post-1994, a landmark year when Pakistan formally adopted the universal salt iodization (USI programme. Overall, 56 studies reported goiter/iodine deficiency prevalence in Pakistan. Before 1994, six studies (30% reported a goiter prevalence ≥70%, while nine studies (45% reported a goiter prevalence between 30% and 70%. Only five studies (25% found a goiter prevalence less than 30%, of which only two studies reported prevalence <10%. From 1994 onwards, 15 studies (41.7% reported a goiter/iodine deficiency (ID prevalence ≥50%, of which seven studies reported prevalence ≥70%, while three studies (8.3% found a goiter prevalence of 30%–49%, nine studies (25% found a goiter prevalence of 10%–29%, and five studies (13.9% reported prevalence of <10%. Four studies (11.1% reported lower goiter prevalence but higher prevalence of iodine deficiency. The efforts in the past two decades resulted in up to a 50% decline in iodine deficiency disorders (IDD. Variable remaining factors and the recent results, however, indicate that this decline may be non-uniform and even over-estimated. Coordinated and regionally adopted efforts for eradication of IDD from all stakeholders should be pursued. Policy makers should take steps to protect future generations and alert concerned organizations about the importance of careful assessments and estimates of iodine nutritional status.

    The phenomenon of globalization has become increasingly well recognized, documented, and analyzed in the last several years. Globalization, the integration of markets and intra-firm competition on a worldwide basis, involves complex behavioral and mindset changes within a firm that facilitate global competition. The changes revolve around efficient information flow and rapid deployment of technology. The objective of this report is to examine the probable characteristics of a global nuclear renaissance and its broad implications for industry structure and export control relative to nuclear technology. The question of how a modern renaissance would affect the trend toward globalization of the nuclear industry is addressed.

    2010-01-01

    Full Text Available Abstract Background Access to HIV and malaria control programmes for refugees and internally displaced persons (IDPs is not only a human rights issue but a public health priority for affected populations and host populations. The primary source of funding for malaria and HIV programmes for many countries is the Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund. This article analyses the current HIV and malaria National Strategic Plans (NSPs and Global Fund approved proposals from rounds 1-8 for countries in Africa hosting populations with refugees and/or IDPs to document their inclusion. Methods The review was limited to countries in Africa as they constitute the highest caseload of refugees and IDPs affected by HIV and malaria. Only countries with a refugee and/or IDP population of ≥ 10,000 persons were included. NSPs were retrieved from primary and secondary sources while approved Global Fund proposals were obtained from the organisation's website. Refugee figures were obtained from the United Nations High Commissioner for Refugees' database and IDP figures from the Internal Displacement Monitoring Centre. The inclusion of refugees and IDPs was classified into three categories: 1 no reference; 2 referenced; and 3 referenced with specific activities. Findings A majority of countries did not mention IDPs (57% compared with 48% for refugees in their HIV NSPs. For malaria, refugees were not included in 47% of NSPs compared with 44% for IDPs. A minority (21-29% of HIV and malaria NSPs referenced and included activities for refugees and IDPs. There were more approved Global Fund proposals for HIV than malaria for countries with both refugees and IDPs, respectively. The majority of countries with ≥10,000 refugees and IDPs did not include these groups in their approved proposals (61%-83% with malaria having a higher rate of exclusion than HIV. Interpretation Countries that have signed the 1951 refugee convention have an obligation

  15. Can people with Raynaud's phenomenon travel to high altitude?

    Luks, Andrew M; Grissom, Colin K; Jean, Dominique; Swenson, Erik R

    2009-01-01

    To determine whether high altitude travel adversely affects mountain enthusiasts with Raynaud's phenomenon. Volunteers with Raynaud's phenomenon were recruited using announcements disseminated by organizations dedicated to climbing or wilderness travel and Internet discussion boards dedicated to mountain activities to complete an online, anonymous survey. Survey questions addressed demographic variables, aspects of their Raynaud's phenomenon, and features of their mountain activities. Respondents compared experiences with Raynaud's phenomenon between high (>2440 m; 8000 feet) and low elevations and rated agreement with statements concerning their disease and the effects of high altitude. One hundred forty-two people, 98% of whom had primary Raynaud's phenomenon, completed the questionnaire. Respondents spent 5 to 7 days per month at elevations above 2440 m and engaged in 5.4 +/- 2.0 different activities. Eighty-nine percent of respondents engaged in winter sports and only 22% reported changing their mountain activities because of Raynaud's phenomenon. Respondents reported a variety of tactics to prevent and treat Raynaud's attacks, but only 12% used prophylactic medications. Fifteen percent of respondents reported an episode of frostbite following a Raynaud's phenomenon attack at high altitude. There was considerable heterogeneity in participants' perceptions of the frequency, duration, and severity of attacks at high altitude compared to their home elevation. Motivated individuals with primary Raynaud's phenomenon, employing various prevention and treatment strategies, can engage in different activities, including winter sports, at altitudes above 2440 m. Frostbite may be common in this population at high altitude, and care must be taken to prevent its occurrence.

  16. Rock’n’Roll as a Local Musical Phenomenon

    2016-02-01

    Full Text Available The paper considers the process of localization of a pop cultural and musical phenomenon – rock ’n’ roll. My basic premise is that rock ’n’ roll as a global music genre can be perceived as local, and hence represents a recognizable identification element for the local population. In this case the label r ’n’ r pertain to the phenomenon of Belgrade "new wave" music, which was popular during the 1980’s. Based on the analysis of narratives from relevant documentary films, it is my intention to find out whether "new wave" was initially perceived as a local phenomenon, and what the means of constructing this image are, as well as what it is that gives this phenomenon local legitimacy and credibility.

  17. Resonance phenomenon in classical cepheids

    Takeuti, Mine; Aikawa, Toshiki

    1981-01-01

    To investigate resonance phenomenon in classical cepheids, the non-linear radial oscillation of stars is studied based on the assumption that the non-adiabatic perturbation is expressed in terms of van der Pol's type damping. Two- and three-wave resonance in this system is applied to classical cepheids to describe their bump and double-mode behavior. The phase of bump and the depression of amplitude are explained for bump cepheids. The double-periodicity is shown by the enhancement of the third overtone in three-wave resonance. Non-linear effect on resonant period is also discussed briefly. (author)

    Allen, Craig D.; Breshears, David D.

    2007-01-01

    An organized oral session at the annual meeting of the Ecological Society of America in San Jose, Calif., posed this question: Is climate-induced drought stress triggering increasing rates and unusual patterns of forest die-off at a global scale? Twenty-nine researchers representing five continents reported on patterns, mechanisms, and projections of forest mortality.Observations include widespread forest dieback or reductions in tree cover and biodiversity in response to drought and warmer temperatures in the African Sahel (Patrick Gonzalez, The Nature Conservancy), Mediterranean and alpine Europe (Jorge Castro, Universidad de Granada), and Argentinean Patagonia (Thomas Kitzberger, Universidad Nacional del Comahue). In contrast, although much Eucalyptus mortality has resulted from recent droughts in Australia, warming trends have been less pronounced in the Southern Hemisphere and it is unclear if contemporary climate-induced tree mortality differs from previous historical drought impacts (Rod Fensham, Queensland Herbarium).

    Florin-Alexandru LUCA

    2018-06-01

    Full Text Available Hybrid war is a reality; war does not depend only on conventional means, but includes communication and propaganda strategies whose role is increasingly important. In the last few years, terrorist cells have spent and keep spending many energies in a global propaganda business. This activity is a fundamental aspect of the conflict. This promotion campaign serves several purposes: legitimating its authority, recruiting militants and motivating sympathizers, and intimidating and conditioning those whose cells they consider enemies. What draws our attention is the sophisticated level of professionalism they demonstrate in managing propaganda and terror. This paper seeks to provide a broader view of the European Foreign Fighters (FF phenomenon by analyzing this target group from a marketing point of view in order to lay the foundations for a strategy to counteract them.

  20. Affective and cognitive effects of global deletion of alpha3-containing gamma-aminobutyric acid-A receptors.

    Fiorelli, Roberto; Rudolph, Uwe; Straub, Carolin J; Feldon, Joram; Yee, Benjamin K

    2008-09-01

    Gamma-aminobutyric acid (GABA)A receptors characterized by the presence of the alpha3 subunit are the major GABAA receptor subtype expressed in brain stem monoaminergic nuclei. These alpha3-GABAA receptors are therefore in a unique position to regulate monoaminergic functions. To characterize the functional properties of alpha3-GABAA receptors, we present a preliminary assessment of the expression of affective and cognitive behaviour in male mice with a targeted deletion of the Gabra3 gene encoding the alpha3 subunit [alpha3 knockout (KO) mice] on a C57BL/6Jx129X1/SvJ F1 hybrid genetic background. The alpha3 KO mice did not exhibit any gross change of anxiety-like behaviour or spontaneous locomotor behaviour. In the Porsolt forced swim test for potential antidepressant activity, alpha3 KO mice exhibited reduced floating and enhanced swimming behaviour relative to wild-type controls. Performance on a two-choice sucrose preference test, however, revealed no evidence for an increase in sucrose preference in the alpha3 KO mice that would have substantiated a potential phenotype for depression-related behaviour. In contrast, a suggestion of an enhanced negative contrast effect was revealed in a one-bottle sucrose consumption test across different sucrose concentrations. These affective phenotypes were accompanied by alterations in the balance between conditioned responding to the discrete conditioned stimulus and to the context, and a suggestion of faster extinction, in the Pavlovian conditioned freezing paradigm. Spatial learning in the water maze reference memory test, however, was largely unchanged in the alpha3 KO mice, except for a trend of preservation during reversal learning. The novel phenotypes following global deletion of the GABAA receptor alpha3 subunit identified here provided relevant insights, in addition to our earlier study, into the potential behavioural relevance of this specific receptor subtypes in the modulation of both affective and cognitive

  1. A review of CCFL phenomenon

    Al Issa, S.; Macian, R.

    2011-01-01

    Highlights: → CCFL mechanisms, correlations, parameters and related variables were reviewed extensively. → Consideration of geometrical effects is crucial for meaningful comparison and review. → Differentiation between 'onset of CCFL' and 'deflooding/partial delivery' data is required. → Following 2+3, new correlations for onset of CCFL according to liquid velocity ranges were suggested. → Large number of correlations was compared against large data bank that considers points 2+3. - Abstract: Counter current flow limitation CCFL is an important phenomenon for numerous engineering applications and safety of light water reactors. In particular, the possible occurrence of CCFL in the hot-leg of a PWR during SBLOCA or LOCA accidents is of special interest for nuclear safety research. A review of the related literature has made in order to present the most important studies about the phenomenon and to reach common general understanding of the different factors that govern CCFL. Eventually this will allow explaining contradictions among different explanations provided by different authors. Most important factors were geometrical characteristics, liquid superficial velocity, and physical properties. The review shows that despite numerous experimental works, many scaling and geometrical effects are still not fully understood. For Instance there exist no consistent explanation of the channel diameter and inclined riser length effect upon results. The same can be stated-though to a minimum extent - for the inclination angle while channel length (or channel to diameter ratio) effect was clear and consistent. Since most experimental work was done in down-scaled hot-leg simulators, it becomes interesting to build a coherent knowledge about these effects and to explain arising contradictions in order to safely extrapolate results to full-scale hot-leg. The review has shown that many differences were simply due to geometrical effects, this leads to the need to

  2. Multilingualism and Hip Hop Consumption in Nigeria: Accounting for the Local Acceptance of a Global Phenomenon Hip-Hop und Mehrsprachigkeit in Nigeria: Zur Erklärung der lokalen Akzeptanz eines globalen Phänomens

    Olusegun Fariudeen Liadi

    2012-01-01

    Full Text Available Hip hop music has enjoyed global popularity and patronage on a level that has transcended that of most other music genres. It is perhaps due to the genre’s worldwide popularity that many forms of hip hop have sprung up across the globe. The Nigerian version of the music has been overwhelmingly accepted by a good number of youths in the country irrespective of class, religion and social status. However, there is some speculation as to what factors are responsible for the recent sudden boom in the popular consumption of this genre among the youth, since hip hop has been a feature of the Nigerian musical landscape since the 1980s. With the aid of qualitative data collection instruments – thirty in-depth interviews and six key informant interviews among hip hop fans and club DJs, respectively – the study establishes the centrality of multilingualism as a primary reason for the acceptance of hip hop among Nigerian youth.Hip-Hop-Musik ist weltweit in einem Maße populär, das die meisten anderen Musikrichtungen übertrifft. Vielleicht hat diese weltweite Beliebtheit dazu geführt, dass rund um den Globus unterschiedliche Formen des Hip-Hop aus dem Boden geschossen sind. Die nigerianische Version dieser Musikrichtung wird von einer überwältigenden Zahl Jugendlicher im Land angenommen, unabhängig von sozialem Status und Religionszugehörigkeit. Es wird jedoch darüber spekuliert, welche Faktoren den jüngsten plötzlichen Boom in dieser Musikrichtung erklären, denn Hip-Hop ist schon seit den 1980er Jahren Teil der nigerianischen Musiklandschaft. Mit Hilfe einer qualitativen Datenerhebung – 30 detaillierte Interviews sowie sechs Interviews mit Schlüsselpersonen unter Hip-Hop-Fans und Club-DJs – kann der Autor die Mehrsprachigkeit als wichtigsten Grund für die Akzeptanz des Hip-Hop unter nigerianischen Jugendlichen ermitteln.

    Full Text Available This article is about increase corruption in private sector as commercial corruption. This establishes a wide understanding of that phenomenon in social science and law. Corruption and bribery are types of fraud and are linked with the private sector too. Although certain types of corruption will decline as the private sector grows and consolidates, other new types involving private sector firms may increase. The commercial corruption can be described as relation inside of an organization and as relation between firms. Corruption in private sector in Poland is connected with social distrust and specific organizational culture, too. Commercial corruption is a familiar feature of their societies and has been the focus of law enforcement and institutional reform. Many others problems do not change the fact that such corruption is a new important problem and causes lost of competitiveness and creates a substitute for fair market and competition in Polish economy and abroad.

    Full Text Available Graham Dinsdale, Ariane L Herrick Centre for Musculoskeletal Research, Institute of Inflammation and Repair, Salford Royal NHS Foundation Trust, University of Manchester, Manchester Academic Health Science Centre, Manchester, UK Abstract: Raynaud's phenomenon (RP is common, and in most patients is primary (idiopathic when due to reversible vasospasm and does not progress to irreversible tissue injury. However, in those patients for whom RP is secondary to an underlying disease (eg, systemic sclerosis or atherosclerosis, progression to digital ulceration or critical ischemia can occur. Therefore, the key question for the clinician is “Why does this patient have RP?” Vascular diagnostics play a key role in answering this. In this review, we firstly discuss the different vascular investigations relevant to clinical practice: nail fold capillaroscopy (including the different methodologies for examining the nail fold capillaries, and the role of capillaroscopy in helping to differentiate between primary and systemic sclerosis-related RP, thermography (available in specialist centers, and evaluation of large vessel disease (for example, due to atherosclerosis. We then discuss research tools, mainly laser Doppler methods, including laser Doppler imaging and laser speckle contrast imaging. These are commercially available as complete imaging systems and are (relatively easy to use. The main current goal in vascular imaging research is to validate these novel state-of-the-art techniques as outcome measures of digital vascular disease, and then apply them in early and later phase studies of new treatment approaches, thus facilitating drug development programs. Keywords: Raynaud's phenomenon, systemic sclerosis, nail fold capillaroscopy, thermography, laser Doppler, angiography

  5. Phenomenon of Uncertainty as a Subjective Experience

    Lifintseva A.A.

    2018-04-01

    Full Text Available The phenomenon of uncertainty in illness of patients is discussed and analyzed in this article. Uncertainty in illness is a condition that accompanies the patient from the moment of appearance of the first somatic symptoms of the disease and could be strengthened or weakened thanks to many psychosocial factors. The level of uncertainty is related to the level of stress, emotional disadaptation, affective states, coping strategies, mechanisms of psychological defense, etc. Uncertainty can perform destructive functions, acting as a trigger for stressful conditions and launching negative emotional experiences. As a positive function of uncertainty, one can note a possible positive interpretation of the patient's disease. In addition, the state of uncertainty allows the patient to activate the resources of coping with the disease, among which the leading role belongs to social support.

  6. Leidenfrost phenomenon on conical surfaces

    Hidalgo-Caballero, S.; Escobar-Ortega, Y.; Pacheco-Vázquez, F.

    2016-09-01

    The Leidenfrost state is typically studied by placing droplets on flat or slightly curved surfaces. Here this phenomenon is investigated by depositing water in hot conical bowls. We found that this phase exists even for large amounts of liquid in very narrow cones without considerable effect of the confinement on the Leidenfrost transition temperature TL. At a fixed temperature, T >TL , the total evaporation time τ has a nonmonotonic dependence on the angle of confinement θ : for large volumes (˜20 ml) on flat surfaces (θ ˜0∘ ), vapor chimneys appear and accelerate the evaporation rate, their frequency diminishes as θ augments and becomes zero at a certain angle θc, at which τ reaches its maximum value; then, τ decreases again at larger angles because the vapor layer holding up the water becomes thinner due to the increase of hydrostatic pressure and because the geometry facilitates the vapor expulsion along the conical wall. For small volumes (˜1 ml), surface tension mainly determines the drop curvature and the lifetime is practically independent of θ . Different chimney regimes and oscillation patterns were observed and summarized in a phase diagram. Finally, we developed a simple model to decipher the shape adopted by the liquid volume and its evolution as a function of time, and the predictions are in good agreement with the experimental results.

  7. [Globalization and infectious diseases].

    Mirski, Tomasz; Bartoszcze, Michał; Bielawska-Drózd, Agata

    2011-01-01

    Globalization is a phenomenon characteristic of present times. It can be considered in various aspects: economic, environmental changes, demographic changes, as well as the development of new technologies. All these aspects of globalization have a definite influence on the emergence and spread of infectious diseases. Economic aspects ofglobalization are mainly the trade development, including food trade, which has an impact on the spread of food-borne diseases. The environmental changes caused by intensive development of industry, as a result of globalization, which in turn affects human health. The demographic changes are mainly people migration between countries and rural and urban areas, which essentially favors the global spread of many infectious diseases. While technological advances prevents the spread of infections, for example through better access to information, it may also increase the risk, for example through to create opportunities to travel into more world regions, including the endemic regions for various diseases. The phenomenon ofglobalization is also closely associated with the threat of terrorism, including bioterrorism. It forces the governments of many countries to develop effective programs to protect and fight against this threat.

  8. Statistical Agent Based Modelization of the Phenomenon of Drug Abuse

    di Clemente, Riccardo; Pietronero, Luciano

    2012-07-01

    We introduce a statistical agent based model to describe the phenomenon of drug abuse and its dynamical evolution at the individual and global level. The agents are heterogeneous with respect to their intrinsic inclination to drugs, to their budget attitude and social environment. The various levels of drug use were inspired by the professional description of the phenomenon and this permits a direct comparison with all available data. We show that certain elements have a great importance to start the use of drugs, for example the rare events in the personal experiences which permit to overcame the barrier of drug use occasionally. The analysis of how the system reacts to perturbations is very important to understand its key elements and it provides strategies for effective policy making. The present model represents the first step of a realistic description of this phenomenon and can be easily generalized in various directions.

  9. The phenomenon of retarded potentials

    Noskov, N.K.

    2003-01-01

    The logic simulation of process of time delay of potential on a moved body - recipient resulted in the deduction about cyclic irregularity of time delay, that means, that the moved body makes longitudinal vibrations. A conclusion is drawn that length of longitudinal vibrations depending from three variable: the law of interaction, spacing interval between bodies of interaction and phase velocity looks like: λ=Hv ph /R·F(R) (1), where λ- length of oscillations; H- factor of proportionality; v ph - phase velocity of a body; R - distance between test and central bodies R(t); F(R) - law of interaction. So far as λ=v ph /v, and R·F(R)=∫ ∞ R F(R)dR=E move , then formula (1) will be transformed into: E move =Hv pv /λ=Hv. Thus, the energy of radiating having the similar law is only reflex of motion of a matter. The energy of oscillating motion can be expressed through linear maximal velocity. It is established, that different expressions of the same energy, result in the law of a view of a proportion for lengths of de Broglie's waves: It shows that de Broglie's waves - the actual oscillating motions of bodies, as demonstrate interference and diffraction pictures at a dissipation of the accelerated particles on crystalline gratings. This deduction has far-reaching consequences for finding - out of the cause bases of the laws of a nature. So, the quantum mechanics becomes partition of mechanics of solids and is comprises all interactions. The nuclear energy is not 'defect of mass', but is 'defect' of energy of oscillating motion: ΔE=H v1 -H v2 . Definition of real cause of nuclear energy is very important for construction of model of nuclei and for development of physics as the whole. The interconnection of the phenomenon of longitudinal vibrations of moved bodies, as result of irregularity of time delay of potential, with many other natural phenomena is looked through. By such, as: motion of planets and electrons on elliptical orbits, oscillating of dipping drips

  10. Risk as a social phenomenon.

    Jamison, Wesley V

    2003-01-01

    What do nuclear power, smoking, and eating beef have in common? The answer is multifaceted. They all share aspects of mass production and consumption, and therefore consumer confidence comes into play in evaluating each of the products' merits. They all produce some level of anxiety--be it in response to adverse media coverage, or the successes of adversarial interest groups in publicizing those products' weaknesses--among consumers who wonder what if any level of the product should be consumed. Finally, nuclear power, smoking, and eating beef all share risk; that is, the perceived and real detriments of producing and consuming those products. Whether or not the associated risks--from increased cancer to increased heart disease--are real is beside the point. When talking about risk, scientific education must deal with the perception of risk as much as its reality. Risk is a socially defined phenomenon, and as such, the successful scientists/communicator must understand the social evaluations of it. While many scientists take a rational view of risk evaluation and consumers often make rational decisions about technological and scientific risk based upon the costs and benefits of that technology, this approach is problematic for three reasons. First, the nature of modern risks has changed in that risk is complex, incomprehensible and uncontrollable to the average person. Second, the rational approach assumes that all costs and benefits of a technology, both real and potential, both current and future, can be known and therefore rationally evaluated. This is not the case. Third, evidence from Europe indicates that trust in information sources about risk has fallen, and thus classic scientific education campaigns that rely upon increasing public knowledge and acceptance of technological and scientific risk are problematic. Because of these factors we argue that effective scientific response must begin to understand the social components of risk if campaigns to shape

    Full Text Available The present study aims to analyze the accounting professionals’ point of view as opposed to the students and master students’ one, regarding the creative accounting phenomenon existence and manifestation forms. In order to accomplish this objective, there has been used the poll/investigation, as a research method and the questionnaire, as a research instrument. Within the study, there is suggested the testing of more hypotheses that contribute to the clarifying of the aspects wished to be analyzed through the research. These hypotheses’ acceptance or rejection is based on the „chi-square“ (Karl Pearson statistical test and rank ordering method. Trying to elaborate a global conclusion of the questionnaire, there could be noticed the fact that over 50% from the questioned accounting students are not tempted to use the creative accounting practices and techniques in order to optimize the taxation without breaking the actual law regulations. At the opposite side, more than a half from the questioned accounting professionals would use these practices without breaking the law regulations that lead to the taxation’s optimization. The creative accounting has a negative connotation if the accurate image of the financial position and of the performance is not targeted because it represents the essential factor for elaborating and grounding the accounting policies. However, the positive side of the creative accounting is not excluded, given that one appeals to the „fair“ professional judgment of the accounting professionals and to the good faith of managers.

    2004-12-01

    Raynaud's phenomenon is a currently vascular syndrome (8 to 10% of women and 3 to 5% of men). It was defined as episodic ischaemia of the fingers, toes, nose, ears and nipples, which presents clinically as pallor, cyanosis, and often rubor of the skins, in response to cold, emotional stimuli and vasoconstriction agents. The phenomenon is caused by a vasoconstriction of arterials skin. In severe forms of the phenomenon, we can see ulcerations and necrosis. We report here two cases of rhytidectomy flap necrosis in Raynaud's Phenomenon. After review of literature, we explain the elements of physiopathology whose can explain these complications and we try to establish recommendations to these complications.

    The informal workers phenomenon on housing construction projects in Indonesia is different from workers in other sectors who would always request as permanent employees. Substantively, the informal workers are disinclined to be bound as permanent employees which different from the general labor paradigm. Hence, the objective of this study is to find out how the labour selection process, the factors that affected their performance, and the suitable wage system to achieve the target completion of housing construction project. The qualitative method is used to uncover and understand the meaning behind the phenomena (numina) of informal workers action and their influence on housing construction project which called phenomenological approach. Five informal workers and two project managers were selected as informants based on predetermined criteria with in-depth interviews. The results showed that the informal worker were more satisfied with the wage based on unit price while working in the housing construction project for the flexibility in working hours. In addition, the developer was also relieved because they only control the quality and the achievement of the project completion time which supported by informal worker leader. Therefore, these findings are beneficial for both of developer and government as policy maker to succeed the housing program in Indonesia.

    ROMANESCU MARCEL LAURENTIU

    2017-02-01

    Full Text Available This article focuses on exemplifying the features of discrimination phenomenon in the workplace, a phenomenon that has appeared in the Romanian social studies only in the last 4 years. Mobbing phenomenon has been analyzed by several countries in Europe such as England, France, Germany; after these analyzes it has been found that this phenomenon refers only to actions of intense psychological pressure. Actions are geared to a single employee, in order to cause it to leave its job. Without these measures, dismissal of the employee would lead to numerous legal problems on the employer. In conclusion, employee who is the subject of mobbing phenomenon must endure a long period of time a series of injustices focused on himself, but also extremely high humiliation, which determines him to mentally give up and take the decision to resign.

    2017-06-20

    The Paris Agreement signed by 195 countries in 2015 sets out a global action plan to avoid dangerous climate change by limiting global warming to remain below 2 °C. Under that premise, in situ experiments were run to test the effects of 2 °C temperature increase on the benthic communities in a seagrass bed and adjacent bare sediment, from a temperate European estuary. Temperature was artificially increased in situ and diversity and ecosystem functioning components measured after 10 and 30 days. Despite some warmness effects on the analysed components, significant impacts were not verified on macro and microfauna structure, bioturbation or in the fluxes of nutrients. The effect of site/habitat seemed more important than the effects of the warmness, with the seagrass habitat providing more homogenous results and being less impacted by warmness than the adjacent bare sediment. The results reinforce that most ecological responses to global changes are context dependent and that ecosystem stability depends not only on biological diversity but also on the availability of different habitats and niches, highlighting the role of coastal wetlands. In the context of the Paris Agreement it seems that estuarine benthic ecosystems will be able to cope if global warming remains below 2 °C.

    Full Text Available The paper problematizes the understanding of the concept of tradition in the context of the world music phenomenon. Marketed as a hybrid music genre, from the perspective of anthropological theory, the world music genre is a complex cultural phenomenon, the result of mixing global and local influences which are reflected not only in the creation of a specific sound, but through different perceptions of music itself (the audience, musicians, producers, creators of cultural policies etc. By analyzing the Serbian world music scene as exemplified by the work of the World Music association of Serbia, as well as the Serbia World Music Festival in Takovo, I will attempt to determine the way in which the concept of world music is perceived in local narratives, whether it is experienced as a form of musical tradition and if so, what is signified and represented as tradition in this context.

  5. Global drought and severe drought-affected populations in 1.5 and 2 °C warmer worlds

    W. Liu

    2018-03-01

    Full Text Available The 2015 Paris Agreement proposed a more ambitious climate change mitigation target on limiting global warming to 1.5 °C instead of 2 °C above preindustrial levels. Scientific investigations on environmental risks associated with these warming targets are necessary to inform climate policymaking. Based on the Coupled Model Intercomparison Project phase 5 (CMIP5 climate models, we present the first risk-based assessment of changes in global drought and the impact of severe drought on populations from additional 1.5 and 2 °C warming conditions. Our results highlight the risk of drought on a global scale and in several hotspot regions such as the Amazon, northeastern Brazil, southern Africa and Central Europe at both 1.5 and 2 °C global warming relative to the historical period, showing increases in drought durations from 2.9 to 3.2 months. Correspondingly, more total and urban populations would be exposed to severe droughts globally (+132.5 ± 216.2 million and +194.5 ± 276.5 million total population and +350.2 ± 158.8 million and +410.7 ± 213.5 million urban populations in 1.5 and 2 °C warmer worlds and regionally (e.g., East Africa, West Africa and South Asia. Less rural populations (−217.7 ± 79.2 million and −216.2 ± 82.4 million rural populations in 1.5 and 2 °C warmer worlds would be exposed to severe drought globally under climate warming, population growth and especially the urbanization-induced population migration. By keeping global warming at 1.5 °C above the preindustrial levels instead of 2 °C, there is a decrease in drought risks (i.e., less drought duration, less drought intensity and severity but relatively more frequent drought and the affected total, urban and rural populations would decrease globally and in most regions. While challenging for both East Africa and South Asia, the benefits of limiting warming to below 1.5 °C in terms of global drought risk

  10. Validation of the Impostor Phenomenon among Managers.

    Rohrmann, Sonja; Bechtoldt, Myriam N; Leonhardt, Mona

    2016-01-01

    Following up on earlier investigations, the present research aims at validating the construct impostor phenomenon by taking other personality correlates into account and to examine whether the impostor phenomenon is a construct in its own right. In addition, gender effects as well as associations with dispositional working styles and strain are examined. In an online study we surveyed a sample of N = 242 individuals occupying leadership positions in different sectors. Confirmatory factor analyses provide empirical evidence for the discriminant validity of the impostor phenomenon. In accord with earlier studies we show that the impostor phenomenon is accompanied by higher levels of anxiety, dysphoric moods, emotional instability, a generally negative self-evaluation, and perfectionism. The study does not reveal any gender differences concerning the impostor phenomenon. With respect to working styles, persons with an impostor self-concept tend to show perfectionist as well as procrastinating behaviors. Moreover, they report being more stressed and strained by their work. In sum, the findings show that the impostor phenomenon constitutes a dysfunctional personality style. Practical implications are discussed.

  11. PP composites with Hybrid Nanofillers: NTC phenomenon

    Sarlin, Juha; Immonen, Kirsi

    2010-01-01

    Electric conductive plastic composites have a wide potential for commercial applications, some examples are EMI shielding housings and components in automotive industry and in consumer electronics, equipments in health care sector and fuel cell components. A phenomenon in conductive composites, especially in composites with carbon based fillers, is change of thermal induced change in conductivity as a result of morphological transitions. Usually the observed changes are practically irreversible. The phenomenon may cause increasing resistivity, usually called as 'positive temperature coefficient' (PTC) or decreasing resistivity, called 'negative temperature coefficient' (NTC), where the new morphology created by heat treatment is more favorable for electric conductivity compared to the original state. The existence of NTC is a sing of the lost potential in material design and processing. Therefore detailed information about the phenomenon gives us tools to develop high performance conductive materials. It this paper we discuss about NTC phenomenon observed in PP composites with CNT or in-situ synthesized CNT-PANi hybrid nanofiller with an amphiphilic dispersing agent. The goal of the paper is not to present a comprehensive model of this phenomenon; we present some experimental results which may be related to polymer-filler interactions. These details are a part of this complicated phenomenon.

    Canada's Green Plan strategy for dealing with global warming is being implemented as a multidepartmental partnership involving all Canadians and the international community. Many of the elements of this strategy are built on an existing base of activities predating the Green Plan. Elements of the strategy include programs to limit emissions of greenhouse gases, such as initiatives to encourage more energy-efficient practices and development of alternate fuel sources; studies and policy developments to help Canadians prepare and adapt to climate change; research on the global warming phenomenon; and stimulation of international action on global warming, including obligations arising out of the Framework Convention on Climate Change. All the program elements have been approved, funded, and announced. Major achievements to date are summarized, including improvements in the Energy Efficiency Act, studies on the socioeconomic impacts of global warming, and participation in monitoring networks. Milestones associated with the remaining global warming initiatives are listed

    This paper applies a nonlinear analysis method to show that hysteresis phenomenon, due to the Saddle-node bifurcation, may occur in the nuclear reactor. This phenomenon may have significant effects on nuclear reactor dynamics and can even be the beginning of a nuclear reactor accident. A system of four dimensional nonlinear ordinary differential equations was considered to study the hysteresis phenomenon in a typical nuclear reactor. It should be noted that the reactivity was considered as a nonlinear function of state variables. The condition for emerging hysteresis was investigated using Routh-Hurwitz criterion and Sotomayor's theorem for saddle node bifurcation. A numerical analysis is also provided to illustrate the analytical results.

    The effect of aerosol particles on ice nucleation and, in turn, the formation of ice and mixed phase clouds is recognized as one of the largest sources of uncertainty in climate prediction. We apply an improved dust mineral specific aerosol module in the NASA GISS Earth System ModelE, which takes into account soil aggregates and their fragmentation at emission as well as the emission of large particles. We calculate ice nucleating particle concentrations from K-feldspar abundance for an active site parameterization for a range of activation temperatures and external and internal mixing assumption. We find that the globally averaged INP concentration is reduced by a factor of two to three, compared to a simple assumption on the size distribution of emitted dust minerals. The decrease can amount to a factor of five in some geographical regions. The results vary little between external and internal mixing and different activation temperatures, except for the coldest temperatures. In the sectional size distribution, the size range 2-4 μm contributes the largest INP number.

We calculate ice nucleating particle concentrations from K-feldspar abundance for an active site parameterization for a range of activation temperatures and external and internal mixing assumption. We find that the globally averaged INP concentration is reduced by a factor of two to three, compared to a simple assumption on the size distribution of emitted dust minerals. The decrease can amount to a factor of five in some geographical regions. The results vary little between external and internal mixing and different activation temperatures, except for the coldest temperatures. In the sectional size distribution, the size range 24 micrometer contributes the largest INP number.

  18. Tullio phenomenon in superior semicircular canal dehiscence syndrome.

    Basura, Gregory J; Cronin, Scott J; Heidenreich, Katherine D

    2014-03-18

    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

  19. Peripheral Sympathectomy for Raynaud's Phenomenon: A Salvage Procedure

    Wen-Her Wang

    2006-10-01

    Full Text Available We retrospectively reviewed the effectiveness of peripheral sympathectomy for severe Raynaud's phenomenon. In this study, a total of 14 digits from six patients with chronic digital ischemic change were included. All patients had pain, ulcer, or gangrenous change in the affected digits and were unresponsive to pharmacologic or other nonsurgical therapies. In all cases, angiography showed multifocal arterial lesions, so microvascular reconstruction was unfeasible. Peripheral sympathectomy was performed as a salvage procedure to prevent digit amputation. The results were analyzed according to reduction of pain, healing of ulcers, and prevention of amputation. In 12 of the 14 digits, the ulcers healed and amputation was avoided. In the other two digits, the ulcers improved and progressive gangrene was limited. As a salvage procedure for Raynaud's phenomenon recalcitrant to conservative treatment, peripheral sympathectomy improves perfusion to ischemic digits and enables amputation to be avoided.

  20. Social Media: A Phenomenon to be Analyzed

    danah boyd

    2015-04-01

    Full Text Available The phenomenon of “social media” has more to do with its cultural positioning than its technological affordances. Rooted in the broader “Web 2.0” landscape, social media helped engineers, entrepreneurs, and everyday people reimagine the role that technology could play in information dissemination, community development, and communication. While the technologies invoked by the phrase social media have a long history, what unfolded in the 2000s reconfigured socio-technical practices in significant ways. Reflecting on the brief history of social media, this essay argues for the need to better understand this phenomenon.

  1. Identification and preliminary characterization of global water resource issues which may be affected by CO/sub 2/-induced climate change

    Callaway, J.M.; Cohen, M.L.; Currie, J.W.

    1984-04-01

    The objectives were to: (1) identify, characterize, and define existing or projected regional and global water resource management issues which may be affected by CO/sub 2/-induced climate changes; and (2) develop research priorities for acquiring additional information about the potential effects of a CO/sub 2/-induced climate change on the availability and allocation of freshwater supplies. The research was broken into four work elements: (1) identification of water resource management issues on a global and regional basis; (2) identification of a subset of generic CO/sub 2/-related water resource management issues believed to have the highest probability of being affected, beneficially or adversely, by a CO/sub 2/-induced climate change; (3) selection of specific sites for examining the potential effect of a CO/sub 2/-induced climate change on these issues; and (4) conducting detailed case studies at these sites, the results from which will be used to identify future research and data needs in the area of water resources. This report summarizes the research related to the first three work elements. 6 figures, 9 tables.

  2. Obesity-metabolic derangement exacerbates cardiomyocyte loss distal to moderate coronary artery stenosis in pigs without affecting global cardiac function.

    2014-04-01

    Obesity associated with metabolic derangements (ObM) worsens the prognosis of patients with coronary artery stenosis (CAS), but the underlying cardiac pathophysiologic mechanisms remain elusive. We tested the hypothesis that ObM exacerbates cardiomyocyte loss distal to moderate CAS. Obesity-prone pigs were randomized to four groups (n = 6 each): lean-sham, ObM-sham, lean-CAS, and ObM-CAS. Lean and ObM pigs were maintained on a 12-wk standard or atherogenic diet, respectively, and left circumflex CAS was then induced by placing local-irritant coils. Cardiac structure, function, and myocardial oxygenation were assessed 4 wk later by computed-tomography and blood oxygenation level dependent (BOLD) MRI, the microcirculation with micro-computed-tomography, and injury mechanisms by immunoblotting and histology. ObM pigs showed obesity, dyslipidemia, and insulin resistance. The degree of CAS (range, 50-70%) was similar in lean and ObM pigs, and resting myocardial perfusion and global cardiac function remained unchanged. Increased angiogenesis distal to the moderate CAS observed in lean was attenuated in ObM pigs, which also showed microvascular dysfunction and increased inflammation (M1-macrophages, TNF-α expression), oxidative stress (gp91), hypoxia (BOLD-MRI), and fibrosis (Sirius-red and trichrome). Furthermore, lean-CAS showed increased myocardial autophagy, which was blunted in ObM pigs (downregulated expression of unc-51-like kinase-1 and autophagy-related gene-12; P < 0.05 vs. lean CAS) and associated with marked apoptosis. The interaction diet xstenosis synergistically inhibited angiogenic, autophagic, and fibrogenic activities. ObM exacerbates structural and functional myocardial injury distal to moderate CAS with preserved myocardial perfusion, possibly due to impaired cardiomyocyte turnover.

  3. SVD identifies transcript length distribution functions from DNA microarray data and reveals evolutionary forces globally affecting GBM metabolism.

    Nicolas M Bertagnolli

    Full Text Available To search for evolutionary forces that might act upon transcript length, we use the singular value decomposition (SVD to identify the length distribution functions of sets and subsets of human and yeast transcripts from profiles of mRNA abundance levels across gel electrophoresis migration distances that were previously measured by DNA microarrays. We show that the SVD identifies the transcript length distribution functions as "asymmetric generalized coherent states" from the DNA microarray data and with no a-priori assumptions. Comparing subsets of human and yeast transcripts of the same gene ontology annotations, we find that in both disparate eukaryotes, transcripts involved in protein synthesis or mitochondrial metabolism are significantly shorter than typical, and in particular, significantly shorter than those involved in glucose metabolism. Comparing the subsets of human transcripts that are overexpressed in glioblastoma multiforme (GBM or normal brain tissue samples from The Cancer Genome Atlas, we find that GBM maintains normal brain overexpression of significantly short transcripts, enriched in transcripts that are involved in protein synthesis or mitochondrial metabolism, but suppresses normal overexpression of significantly longer transcripts, enriched in transcripts that are involved in glucose metabolism and brain activity. These global relations among transcript length, cellular metabolism and tumor development suggest a previously unrecognized physical mode for tumor and normal cells to differentially regulate metabolism in a transcript length-dependent manner. The identified distribution functions support a previous hypothesis from mathematical modeling of evolutionary forces that act upon transcript length in the manner of the restoring force of the harmonic oscillator.

  4. "Developing culturally sensitive affect scales for global mental health research and practice: Emotional balance, not named syndromes, in Indian Adivasi subjective well-being".

    Snodgrass, Jeffrey G; Lacy, Michael G; Upadhyay, Chakrapani

    2017-08-01

    We present a perspective to analyze mental health without either a) imposing Western illness categories or b) adopting local or "native" categories of mental distress. Our approach takes as axiomatic only that locals within any culture share a cognitive and verbal lexicon of salient positive and negative emotional experiences, which an appropriate and repeatable set of ethnographic procedures can elicit. Our approach is provisionally agnostic with respect to either Western or native nosological categories, and instead focuses on persons' relative frequency of experiencing emotions. Putting this perspective into practice in India, our ethnographic fieldwork (2006-2014) and survey analysis (N = 219) resulted in a 40-item Positive and Negative Affect Scale (PANAS), which we used to assess the mental well-being of Indigenous persons (the tribal Sahariya) in the Indian states of Rajasthan and Madhya Pradesh. Generated via standard cognitive anthropological procedures that can be replicated elsewhere, measures such as this possess features of psychiatric scales favored by leaders in global mental health initiatives. Though not capturing locally named distress syndromes, our scale is nonetheless sensitive to local emotional experiences, frames of meaning, and "idioms of distress." By sharing traits of both global and also locally-derived diagnoses, approaches like ours can help identify synergies between them. For example, employing data reduction techniques such as factor analysis-where diagnostic and screening categories emerge inductively ex post facto from emotional symptom clusters, rather than being deduced or assigned a priori by either global mental health experts or locals themselves-reveals hidden overlaps between local wellness idioms and global ones. Practically speaking, our perspective, which assesses both emotional frailty and also potential sources of emotional resilience and balance, while eschewing all named illness categories, can be deployed in

  7. Key-Phenomenon and Religious Meaning

    Lomuscio Vincenzo

    2017-09-01

    Full Text Available In this paper I develop a phenomenology of religious experience through the notion of keyphenomenon. My analysis moves from a general phenomenology of situation, in which we have to relate different phenomena according to a sense. What does “according to a sense” mean? My suggestion is that we should look for a relationship among these data when we find a key-phenomenon (among a series of phenomena that would enlighten all the others. This key-phenomenon would show a non-phenomenal meaning which would make all the others understandable. Each other datum, therefore, becomes the witness of invisible meaning through a key-witness. The key-phenomenon we choose determines the role (i.e., the truth of each datum within its situation. This phenomenological relationship belongs to both the sense of day-life situations, and that one of possible religious situations. If the religious interpretation of a situation depends on our choice of key-phenomenon, or key-witness, we have to define what kind of keyphenomenon constitutes a religious intuition.

  10. Analysis of factors that affect shoulder balance after correction surgery in scoliosis: a global analysis of all the curvature types.

    Hong, Jae-Young; Suh, Seung-Woo; Modi, Hitesh N; Yang, Jae-Hyuk; Park, Si-Young

    2013-06-01

    To identify factors that can affect postoperative shoulder balance in AIS. 89 adolescent idiopathic scoliosis patients with six types of curvatures who underwent surgery were included in this study. Whole spine antero-posterior and lateral radiographs were obtained pre- and postoperatively. In radiograms, shape and changes in curvatures were analyzed. In addition, four shoulder parameters and coronal balance were analyzed in an effort to identify factors significantly related to postoperative shoulder balance. In general, all the four shoulder parameters (CHD, CA, CRID, RSH) were slightly increased at final follow up (t test, P shoulder parameters were not significantly different between each curvature types (ANOVA, P > 0.05). Moreover, no significant differences of pre- and postoperative shoulder level between different level of proximal fusion groups (ANOVA, P > 0.05) existed. In the analysis of coronal curvature changes, no difference was observed in every individual coronal curvatures between improved shoulder balance and aggravated groups (P > 0.05). However, the middle to distal curve change ratio was significantly lower in patients with aggravated shoulder balance (P shoulder imbalance showed the higher chance of aggravation after surgery with similar postoperative changes (P shoulder balance. In addition, preoperative shoulder level difference can be a determinant of postoperative shoulder balance.

  11. Facial dysmorphopsia: a notable variant of the "thin man" phenomenon?

    Ganssauge, Martin; Papageorgiou, Eleni; Schiefer, Ulrich

    2012-10-01

    The aim of this work is to investigate the facial distortion (dysmorphopsia) experienced by patients with homonymous paracentral scotomas and to analyze the interrelationship with the previously described "thin man" phenomenon. Routine neuro-ophthalmological examination and brain MRI in three patients who suffered from small homonymous paracentral scotomas due to infarction or arteriovenous malformations of the occipital lobe. They all complained of distortion and shrinkage of their interlocutor's face contralateral to the brain lesion. The phenomenon appeared some seconds after steady fixation on the interlocutor's nose and was evident with both left and right homonymous scotomas. The patients did not notice a gap in the area corresponding to the scotoma and objects other than faces were perceived normally. Homonymous paracentral scotomas can lead to focal displacement of facial features towards the center of the field defect with resulting distortion of the face on the affected side. This so-called "dysmorphopsia" makes faces appear regionally narrower than they are in reality and may be induced even by visual field defects that remain undetected by conventional perimetry using 6° × 6° grids. Predilection for faces is probably associated with the superior location of scotomas or specific impairment of face processing abilities related to the lesion site. Facial dysmorphopsia is most probably associated with cortical "filling-in" and spatial distortion, and can hence be regarded as a special entity of the "thin man" phenomenon.

    This volume contains a contemporary, integrated description of the processes of language. These range from fast scales (fractions of a second) to slow ones (over a million years). The contributors, all experts in their fields, address language in the brain, production of sentences and dialogues, language learning, transmission and evolutionary processes that happen over centuries or millenia, the relation between language and genes, the origins of language, self-organization, and language competition and death. The book as a whole will help to show how processes at different scales affect each other, thus presenting language as a dynamic, complex and profoundly human phenomenon.

  13. Security Components of Globalization

    Florin Iftode

    2015-05-01

    Full Text Available The objective of this paper is our intention to present what are the main connections between globalization and international security. In terms of global security we can perceive the globalization as a process by which global state is represented by the UN, with a single world system, represented by major security organizations and with global effects. We will present from the beginning the main theoretical aspects that define the phenomenon of globalization, and then our contribution in assessing the implications of this phenomenon on the regional and global security. The results of our research are materialized in the last part of the paper. They emphasize the personal assessments on how the phenomenon of globalization has direct effect on global security. When talking about government, we think of norms, rules and decisionmaking procedures in the management of international life. The value that we add to the new scientific interpretation of the definition of globalization is represented, primarily, by the valuable bibliographic used resources and the original approach on the concept that refers to the links between globalization and security. This article may be, at any time, a starting point in an interesting research direction in the field of global security.

  14. Phase transition phenomenon: A compound measure analysis

    Kang, Bo Soo; Park, Chanhi; Ryu, Doojin; Song, Wonho

    2015-06-01

    This study investigates the well-documented phenomenon of phase transition in financial markets using combined information from both return and volume changes within short time intervals. We suggest a new measure for the phase transition behaviour of markets, calculated as a return distribution conditional on local variance in volume imbalance, and show that this measure successfully captures phase transition behaviour under various conditions. We analyse the intraday trade and quote dataset from the KOSPI 200 index futures, which includes detailed information on the original order size and the type of each initiating investor. We find that among these two competing factors, the submitted order size yields more explanatory power on the phenomenon of market phase transition than the investor type.

  15. The veining phenomenon in unalloyed plutonium

    White, J.S.

    1976-01-01

    An investigation has been made of the veining phenomenon in unalloyed plutonium. The surface markings, or veins, which are sometimes seen on α-phase plutonium samples, arise as a result of the β→α transformation. As far as is known, this veining is unrivalled in its scale and form as compared with the solid state surface transformation effects shown by any other metal. The phenomenon has been explained by the application of the Le Chatelier principle to the phase change. In this instance, the large (10%) volume contraction associated with the β→α reaction and the anisotropy of the nonoclinic α-phase structure, account for the fact that the veins are so prominent in plutonium. On the basis of the proposed model, the veins can only form at temperatures where the transformation mechanism is non-martensitic. (Auth.)

  16. Diffusion phenomenon for linear dissipative wave equations

    Said-Houari, Belkacem

    2012-01-01

    In this paper we prove the diffusion phenomenon for the linear wave equation. To derive the diffusion phenomenon, a new method is used. In fact, for initial data in some weighted spaces, we prove that for {equation presented} decays with the rate {equation presented} [0,1] faster than that of either u or v, where u is the solution of the linear wave equation with initial data {equation presented} [0,1], and v is the solution of the related heat equation with initial data v 0 = u 0 + u 1. This result improves the result in H. Yang and A. Milani [Bull. Sci. Math. 124 (2000), 415-433] in the sense that, under the above restriction on the initial data, the decay rate given in that paper can be improved by t -γ/2. © European Mathematical Society.

  17. Phenomenon of displacement in Arabic language

    2015-09-01

    Full Text Available Displacement is one of the characteristics of language and common phenomena in the Arabic language. Not only is this phenomenon limited to Arabic poetry and prose, but it is also broadened, so we can see examples of this in the Qur'an. Because of this phenomenon extensively in Arabic literature and also because of its essence that leads to the transmission of the elements for the first visibility to the other visibility in the sentence and sometimes had to change the grammatical role of the words, its identify helps us in a better understanding of text and the correct translation of it and protects the reader from mistakes. This paper in the descriptive analytical approach tries studying of the phenomenon of the displacement in the Arabic language and bringing its instances in Arabic poetry and prose as well as verses contained in the Holy Quran, to show that through the types and characteristics in the Arabic language and to response to several questions, including: how important is the displacement and what is its types in rhetoric, and the reasons of the displacement, and etc... Of the most important results of this study may refer to the undeniable role of the displacement as a rhetorical method to better understanding of the texts including: one of the most important reasons of the displacement in the use of language is to improve speech verbally and morally, and violation of the standard language and create a poetic atmosphere, and the recognition of the occurrence of the phenomenon of displacement in the Arabic language that uphold different interpretations remote and estimates when faced with the displacement in the text and help us to understand it and etc...

  19. THE PHENOMENON OF MIGRATION. OPPORTUNITIES AND CHALLENGES

    Carmen BOGHEAN

    2016-07-01

    Full Text Available Migration is not a new phenomenon, neither for Europe, nor for the entire world and it exists since the beginning of mankind. Over time, this kind of international mobility generated many opportunities, but many challenges as well. Being an extremely important and complex phenomenon, both in economic terms and mostly from the social perspective, mass emigration has never been more intense as nowadays. Together with this particular complexity, the intensity of the migration phenomenon reveals each individual’s profound freedom desire, but also the acute need to ensure a better future for himself and especially for his family. Currently, an ever increasing number of individuals migrate in search of a better place, changing regions, countries or even continents. Witnessing the events that transcend the people all around the world, we consider that migration generates economic, social and cultural, but also political profound changes. These major changes require the involvement of the political actors, namely the governments, in creating a favorable and reliable framework so as the society and decision makers to understand that immigrants represent an opportunity for the emerging economies and not a phenomenon that should be criticized. In this paper we aim to follow the theories regarding the migration process, as well as the changes it generates, taking into consideration that of the 507 million current inhabitants of the EU, approximately 20 million are from countries outside the EU. We consider this research to be underlain, taking into consideration that regardless of the form it takes, in Europe immigration is and will remain a difficult to manage reality.

  20. Phenomenon of political actionism in modern society

    V. M. Bavykina

    2016-08-01

    Full Text Available Political actionism is the fenomen in social and art space, that appeared in middle of XX century as the practice of critic and protest with using different artistic methods and techniques. Political actionism as art and political tradition exist in postsoviet space, especially in Russia where actionism appeared in 1990 years and develops for actually days. In other countries this phenomenon not such systematic.  But analyze and compare actions in different countries appears the possibility to understand social and cultural context, their difference and similarity. Actionism is a reaction to external public, social and political situation, but its appearance more like the symptom of some problem than its critic or display – traditional approaches in art.  Appearance of actionism also connected with inability of manifestation of personal and civil liberty, that’s why in actions liberty affairs in such radical and hyperbolized forms. First volume of Russian political actionism began in 1990 years (Oleg Kulik, Alexander Brener, Anatoly Osmolovsky etc. and Second volume in 2010 (art-group Voina, Pussy Riot, Pyotr Pavlensky. This process not only a transformation of artistic and traditional space, but also modification of reaction on social and political situation. Actionism becomes a source of new type of knowledge, that give a possibility to see the habitual reality from another side and find in it new pointes and concepts. Political actionism contracting own interpretation of already well-established phenomenon. Usual concepts of liberty, authority, social control are deconstructed in actions. Those destructions of reality and cultural reorientation destroys traditional imposed patterns of interaction and social structure. But new views, that appeared in daily life from actions, often has mistaken interpretations. Exist a problem about identification of actions, its correct interpretations and understanding of its causes. In article was

    This article pays critical attention to the ways in which academic feminism has regarded religion. Issues related to religion and gender have by and large either been ignored or treated quite stereotypically. I have called this phenomenon a simultaneous under- and overestimation of religion. The phenomenon is not global. Feminists of the global south tend to pay much more and more multi-faceted attention to religion than scholars from the global north.

  2. The Overshoot Phenomenon in Geodynamics Codes

    Kommu, R. K.; Heien, E. M.; Kellogg, L. H.; Bangerth, W.; Heister, T.; Studley, E. H.

    2013-12-01

    The overshoot phenomenon is a common occurrence in numerical software when a continuous function on a finite dimensional discretized space is used to approximate a discontinuous jump, in temperature and material concentration, for example. The resulting solution overshoots, and undershoots, the discontinuous jump. Numerical simulations play an extremely important role in mantle convection research. This is both due to the strong temperature and stress dependence of viscosity and also due to the inaccessibility of deep earth. Under these circumstances, it is essential that mantle convection simulations be extremely accurate and reliable. CitcomS and ASPECT are two finite element based mantle convection simulations developed and maintained by the Computational Infrastructure for Geodynamics. CitcomS is a finite element based mantle convection code that is designed to run on multiple high-performance computing platforms. ASPECT, an adaptive mesh refinement (AMR) code built on the Deal.II library, is also a finite element based mantle convection code that scales well on various HPC platforms. CitcomS and ASPECT both exhibit the overshoot phenomenon. One attempt at controlling the overshoot uses the Entropy Viscosity method, which introduces an artificial diffusion term in the energy equation of mantle convection. This artificial diffusion term is small where the temperature field is smooth. We present results from CitcomS and ASPECT that quantify the effect of the Entropy Viscosity method in reducing the overshoot phenomenon. In the discontinuous Galerkin (DG) finite element method, the test functions used in the method are continuous within each element but are discontinuous across inter-element boundaries. The solution space in the DG method is discontinuous. FEniCS is a collection of free software tools that automate the solution of differential equations using finite element methods. In this work we also present results from a finite element mantle convection

  3. Nothingness and the placebo effect phenomenon

    Jensen, Tine

    The placebo effect is a pharmacological conundrum, since it is a medical effect that is produced by “nothing” because no pharmacologically active substance is present in placebo. Placebo has, among other things, been defined as an inert substance, often a calcium pill. Simultaneously it presents...... a posthuman angle, applying Karen Barad’s concept of agential realism to tackle the issue of nothingness. I argue that the placebo effect produces specific agencies in the placebo effect phenomenon – that is, both the subject under treatment and the placebo emerge in the placebo effect in the act of measuring it...

  6. Magnetic poles and a still unexplained phenomenon

    Trower, W.P.

    1981-01-01

    A review is given of ideas about magnetic monopoles. Attention is drawn to the still unexplained observations of Schein, Haskin and Glasser (1954), in which electron-positron pairs were produced in large numbers by a cosmic-ray interaction. Their experiment has been simulated in 300 GeV pN interactions at Fermilab, giving a production limit of 10 -7 per proton interaction. The explanation for this phenomenon may lie in magnetic monopoles, or it may be similar to that invoked to explain the so-called Centauro events. (A.W.)

  7. Exploration of transnationalism as a concept and phenomenon in Public Administration

    Barry Hanyane

    2015-12-01

    Full Text Available Transnationalism as both a phenomenon and a concept has received negligible attention in modern times in relation to the practice of public administration and its corresponding field of study. This article provides an account of the meaning and the relevance of both the concept and phenomenon as received and applied by practitioners and scholars in the said practice and field of study. From the latter, a deliberate approach towards policy matters is undertaken in relation to the concept and phenomenon of transnationalism. In this article policies used by the national Department of Home Affairs in South Africa form the basis from which a case is made relevant to this topic in p(Public a(Administration. Additionally, case studies in the SADC region are considered. This article therefore argues that transnationalism is as much local as global issues such as immigration, citizenship, global economy, service delivery, government (inefficiency and (ineffectiveness and such other matters of public interest.

  8. Global warming

    Hulme, M

    1998-01-01

    Global warming-like deforestation, the ozone hole and the loss of species- has become one of the late 20the century icons of global environmental damage. The threat, is not the reality, of such a global climate change has motivated governments. businesses and environmental organisations, to take serious action ot try and achieve serious control of the future climate. This culminated last December in Kyoto in the agreement for legally-binding climate protocol. In this series of three lectures I will provide a perspective on the phenomenon of global warming that accepts the scientific basis for our concern, but one that also recognises the dynamic interaction between climate and society that has always exited The future will be no different. The challenge of global warning is not to pretend it is not happening (as with some pressure groups), nor to pretend it threatens global civilisation (as with other pressure groups), and it is not even a challenge to try and stop it from happening-we are too far down the ro...

    1988-12-01

    A 75 years old white male, for 3 years on treatment for virchowian hanseniasis, was admitted with active HD lesions, infiltration on the base of right lung, leg ulcer and malaise. After two days he developed purpura and hemorrhagic blisters in the limbs. The biopsy of these lesions revealed Lucio phenomenon. The patient worsened with mental confusion, psychomotor agitation and anisocoric pupils. In the 18th day of internation the patient died. Necropsy revealed virchowian infiltration plenty of bacilli in the skin and viscera as well as tuberculoid granuloma with acid-fast bacilli in the liver, spleen and bone marrow. These findings lead us to review the patient's classification from virchowian to borderline. In the lungs, leptomeninge, renal papile, prostate and thyroid it was found loose tuberculoid granuloma with a great amount of fungi surrounded by a gelly halo resembling Criptococcus neoformans. These findings and the onset of Lucio phenomenon are discussed in a patient that has been treated for 3 years and still having several virchowian lesions and a great amount of acid-fast bacilli.

    To evaluate the characteristic color doppler imaging of vertebral artery flow in the subclavian steal phenomenon. The study group consisted of eight patients with reversed vertebral artery flow proved by color Doppler imaging. We classified this flow into two groups:(1) complete reversal;(2) partial reversal, as shown by Doppler velocity waveform. Vertebral angiography was performed in six of eight patients;color Doppler imaging and angiographic findings were compared. On color Doppler imaging, all eight cases with reversed vertebral artery flow showed no signal at the proximal subclavian or brachiocephalic artery. We confirmed shunting of six cases by performing angiography from the contralateral vertebral and basilar artery to the ipsilateral vertebral artery. On the Doppler spectrum, six cases showed complete reversal and two partial reversal. On angiography, one partial reversal case showed complete occlusion of the subclavian artery with abundant collateral circulation of muscular branches of the vertebral artery. On color Doppler imaging, a reversed vertebral artery suggests the subclavian steal phenomenon. In particular, partial reversal waveform may reflect collateral circulation

    Full Text Available Children’s attribution of emotions to a moral transgressor is an important research topic in the psychology of moral and emotional development. This is especially because of the so-called Happy Victimizer Phenomenon (HVP where younger children attribute positive emotions to a moral transgressor described in a story. In the two studies that we have conducted (children aged 5, 7 and 9, 20 of each age; 10 of each age in the second study we have tested the possible influence of the fear of sanctions and the type of transgression (stealing and inflicting body injuries on the attribution of emotions. Children were presented with stories that described transgressions and they were asked to answer how the transgressor felt. The fear of sanctions did not make a significant difference in attribution but the type of transgression did - more negative emotions were attributed for inflicting body injuries than for stealing. Positive emotions were explained with situational-instrumental explanations in 84% of cases while negative emotions were explained with moral explanations in 63,5%. Girls attributed more positive emotions (61% than boys (39%. However, our main finding was that, for the aforementioned age groups, we did not find the HVP effect although it has regularly been registered in foreign studies. This finding denies the generalizability of the phenomenon and points to the significance of disciplining styles and, even more so, culture for children’s attribution of emotions to moral transgressors.

    2006-08-01

    After the broad industrialization of the US pork industry, there has been a development of niche markets for export and domestic pork; that is, there is a pork niche market phenomenon. The US pork niche market phenomenon is characterized, and 2 of the major markets are explained in detail. With the Midwest's tradition of a diversified family-based agriculture and record low hog prices of the late 1990s, the conditions were conducive for this phenomenon to develop. Pork niche markets utilize various sales methods including Internet sales, local abattoir sales, direct marketing, farmer networks, and targeting to organized groups. In 2003, there were approximately 35 to 40 active pork niche marketing efforts in Iowa. The Berkshire breed is an example of a swine breed that has had a recent resurgence because of niche markets. Berkshire pork is known for tenderness and excellent quality. Berkshire registrations have increased 4-fold in the last 10 yr. One of the larger niche marketers of "natural pork" is Niman Ranch Pork, which has more than 400 farmer-producers and processes about 2,500 pigs weekly. Many US consumers of pork are interested in issues concerning the environment, food safety, pig welfare, and pig farm ownership and structure. These consumers may be willing to pay more for pork from farmers who are also concerned about these issues. Small- and medium-sized swine farmers are active in pork niche markets. Niche markets claim product differentiation by superior or unique product quality and social attributes. Quality attributes include certain swine breeds, and meat quality, freshness, taste or flavor, and tenderness. Social or credence attributes often are claimed and include freedom from antibiotics and growth promotants; local family farm production; natural, organic, outdoor, or bedded rearing; humane rearing; known origin; environmentally friendly production; and the absence of animal by-products in the feed. Niche pork markets and alternative swine

  14. Melting phenomenon and laser annealing in semiconductors

    Narayan, J.

    1981-03-01

    The work on annealing of displacement damage, dissolution of boron precipitates, and the broadening of dopant profiles in semiconductors after treating with ruby and dye laser pulses is reviewed in order to provide convincing evidence for the melting phenomenon and illustrate the mechanism associated with laser annealing. The nature of the solid-liquid interface and the interface instability during rapid solidification is considered in detail. It is shown that solute concentrations after pulsed laser annealing can far exceed retrograde maxima values. However, there is a critical solute concentration above which a planar solid-liquid interface becomes unstable and breaks into a cellular structure. The solute concentrations and cell sizes associated with this instability are calculated using a perturbation theory, and compared with experimental results

  15. [Electroencephalographic characteristics of the deja vu phenomenon].

    Vlasov, P N; Cherviakov, A V; Gnezdinsiĭ, V V

    2013-01-01

    Déjà vu (DV, from French "already seen") is an aberration of psychic activity associated with transitory erroneous perception of novel circumstances, objects, or people as already known. An aim of the study was to investigate EEG characteristics of DV in patients with epilepsy. We studied 166 people (63.2% women, mean age 25.17±9.19 years). The DV phenomenon was studied in patients (27 people) and in a control group (139 healthy people). Patients were interviewed for DV characteristics and underwent a long (12-16 h) ambulatory EEG-monitoring study. In EEG, DV episodes in patients began with polyspike activity in the right temporal lobe and, in some cases, ended with the slow-wave theta-delta activity in the right hemisphere.

  18. Environmental logistics performance indicators affecting per capita income and sectoral growth: evidence from a panel of selected global ranked logistics countries.

    Khan, Syed Abdul Rehman; Qianli, Dong; SongBo, Wei; Zaman, Khalid; Zhang, Yu

    2017-01-01

    The objective of the study is to examine the long-run and causal relationship between environmental logistics performance indicators (ELPI) and growth-specific factors in a panel of 15 selected global ranked logistics countries over a period of 2007-2015. This study is exclusive as we utilized a number of LPI factors including logistics performance, logistics competence, and logistics infrastructure with mediation of sustainable factors, i.e., carbon dioxide (CO 2 ), fossil fuel, and greenhouse gas (GHG) emissions in a region. The results show that the per capita income, industry, manufacturing, and service share to GDP is affected by CO 2 emissions and GHG emissions. Logistics competence and infrastructure promote economic growth and sectoral value added, while energy demand and FDI inflows both are prerequisite for sustainable agriculture in a region. The causal relationships confirm that more energy demand results in an increase in economic growth, industry value added, and the service sector (i.e., feedback hypothesis), while the sustainable supply chain system improves energy demand, FDI inflows, economic growth, and sectoral growth (i.e., conservation hypothesis) in a panel of countries.

  19. Prussian phenomenon and its historical distortion

    Oleg Y. Plenkov

    2016-03-01

    Full Text Available The article deals with the phenomenon of Prussia. Once, Prussia had been the largest continental Protestant state in Europe. The main issue of this phenomenon is that upon the tragic events of the World War II Prussian history and heritage had been considerably distorted, in order to compensate somehow for the dreadful casualties suffered by the victorious powers. The common European misconception implied that Prussia had been the bulwark of militarism, and therefore had to bear all the responsibility for the atrocities of war. Unfortunately, the majority of modern German historians share such misinterpretation of Prussian heritage in order to please false political correctness, perhaps, as an act of contrition for National Socialism and its crimes. However, the Prussian tradition and history go far beyond this militarism, and this article explains what ways. The authors believe that there should not be any prejudices and biases, that any subject should be examined sine ira et studio. Moreover, given that it is possible to characterize the Great French Revolution as a juristic one, and the Great October revolution – as a social one, the Prussian revolution “from above”, led by the first representatives of the Hohenzollern family, may be well considered as a pedagogical revolution. This revolution did bring definitely positive changes; they are surveyed in the article. The French Revolution has not eliminated the covetousness of the bourgeoisie after 1789; despotism of the authorities and people’s passiveness similarly have remained unaltered in Russia after 1917. On the contrary, Federal Republic of Germany of nowadays, distinctive for its law, order and effective responsible government is unthinkable without Prussian heritage.

  2. Discrete numerical investigation of the ratcheting phenomenon in granular materials

    Calvetti, Francesco; di Prisco, Claudio

    2010-10-01

    Several relevant geotechnical works, such as railway and road embankments, offshore foundations and vibrating machine foundations, are affected by the progressive accumulation of irreversible settlements. These latter represent the macroscopic evidence of the progressive rearrangement of particles under cycling loading, which is commonly referred to, in the literature, as ratcheting. This phenomenon is well known, but it is quite difficult to describe it by means of an appropriate constitutive model. As a consequence, the evaluation of durability of the aforementioned structures remains an open problem. In this article, the phenomenon will be approached by employing a Distinct Element model capable of describing the evolution of the microstructure induced by cyclic mechanical perturbations. Several analyses are performed in order to stress the influence of both the stress level and loading history on the mechanical response of a numerical model of a sand specimen. The numerical analyses are intended to provide an experimental background for conceiving a simplified macro approach based on generalised plasticity theory. In particular by means of probe test the plastic potential and the hardening parameters will be defined as a function of the current stress state and loading history.

  3. Transit of Venus Culture: A Celestial Phenomenon Intrigues the Public

    Bueter, Chuck

    2012-01-01

    When Jeremiah Horrocks first observed it in 1639, the transit of Venus was a desirable telescopic target because of its scientific value. By the next transit of Venus in 1761, though, the enlightened public also embraced it as a popular celestial phenomenon. Its stature elevated over the centuries, the transit of Venus has been featured in music, poetry, stamps, plays, books, and art. The June 2004 transit emerged as a surprising global sensation, as suggested by the search queries it generated. Google's Zeitgeist deemed Venus Transit to be the #1 Most Popular Event in the world for that month. New priorities, technologies, and media have brought new audiences to the rare alignment. As the 2012 transit of Venus approaches, the trend continues with publicly accessible capabilities that did not exist only eight years prior. For example, sites from which historic observations have been made are plotted and readily available on Google Earth. A transit of Venus phone app in development will, if fully funded, facilitate a global effort to recreate historic expeditions by allowing smartphone users to submit their observed transit timings to a database for quantifying the Astronomical Unit. While maintaining relevance in modern scientific applications, the transit of Venus has emerged as a cultural attraction that briefly intrigues the mainstream public and inspires their active participation in the spectacle.

    2014-01-01

    Thermal stratification phenomenon of pressurizer surge line can lead potential threaten to plant safety. Base on the mechanism of thermal stratification occurrence, Fr number is used to judge whether the stratification occurs or not. Also the method of calculating heat transfer coefficient is investigated. Theoretically the 3-dimension thermal stress induced by thermal stratification is decoupled to 1-dimension global stress and 2-dimension local stress, and the complex 3-dimension problem is simplified into a combination of 1-dimension and 2-dimension to compute the stress. Comply with criterion RCC-M, the complete structure integrity evaluation is accomplished after combining the stress produced by thermal stratification and the stresses produced by the other loadings. In order to match the above combined analysis method, Code SYSTUS and ROCOCO are developed. By means of aforesaid evaluation method and corresponding analysis program, surge line thermal stratification of Qinshan Phase II Extension project is investigated in this paper. And the results show that structural integrity of the pressurizer surge line affected by thermal stratification still satisfies criterion RCC-M. (authors)

  5. European Integration and Globalization

    Diana Bobica

    2010-06-01

    Full Text Available According to many, the term globalization is able to explain any phenomenon whatsoever, be it positive or negative, that takes place within the global social system. It seems like a sort of magical formula, which is to be found in the speeches of all sorts of people, be they economists, politicians, businessmen or sociologists. However this magical formula of globalization has its limitations, since it encompasses a certain amount of quibbling, beyond which not many can pass. In the context of globalization there appears the question on its role in the process of European integration. Is European integration a part of this global process or, quite on the contrary, does it present certain distinctive features, as it moulds itself differently from the globalization phenomenon? A clear-cut answer seems difficult because of the various aspects involved. Not only the general phenomenon of globalization, but also the economic integration on European level is based on the liberalization of markets and on the opening of national economies towards the exterior,having as direct consequence the intensification of trade exchanges. If from a global point of view one may talk of a market fundamentalism in that the market principles know no boundary, European integration on the other hand implies not only market economy, but also a guided and monitored action of Member Statesaccording to the needs of the whole entity, also taking into consideration - as far as possible – all aspects and consequences on social level.

  8. Priming intelligent behavior: an elusive phenomenon.

    David R Shanks

    Full Text Available Can behavior be unconsciously primed via the activation of attitudes, stereotypes, or other concepts? A number of studies have suggested that such priming effects can occur, and a prominent illustration is the claim that individuals' accuracy in answering general knowledge questions can be influenced by activating intelligence-related concepts such as professor or soccer hooligan. In 9 experiments with 475 participants we employed the procedures used in these studies, as well as a number of variants of those procedures, in an attempt to obtain this intelligence priming effect. None of the experiments obtained the effect, although financial incentives did boost performance. A Bayesian analysis reveals considerable evidential support for the null hypothesis. The results conform to the pattern typically obtained in word priming experiments in which priming is very narrow in its generalization and unconscious (subliminal influences, if they occur at all, are extremely short-lived. We encourage others to explore the circumstances in which this phenomenon might be obtained.

    Full Text Available the article is devoted to the study of virtual reality as a social phenomenon. Through an appeal to the past, its genesis is analyzed, as well as its significance in modern realities. The latter is viewed from both a social and a personal point of view. Comparing the number of supporters of virtual communication with the number of people of conservative views, conclusions are drawn about the tendency to depart from the usual communication. It allows to assert that the problem of the termination of live communication is relevant to this day. Inferences allow us to assert that the problem of replacing real communication is different. After looking at the positive consequences, the introduction of the mind into virtual reality, it is affirmed that there are good sides to this action. Through analysis, the causes of entering the World Wide Web are generated. In conclusion, the question is raised about the need for virtual reality in everyday life, its problems, as well as the prospects for development.

  10. The keloid phenomenon: progress toward a solution.

    Louw, Louise

    2007-01-01

    For centuries, keloids have been an enigma and despite considerable research to unravel this phenomenon no universally accepted treatment protocol currently exists. Historically, the etiology of keloids has been hypothesized by multiple different theories; however, a more contemporary view postulates a multifactoral basis for this disorder involving nutritional, biochemical, immunological, and genetic factors that play a role in this abnormal wound healing. Critical to the process of preventing or managing keloids is the need to locally control fibroblasts and their activities at the wound site. In recent years, considerable evidence has accumulated demonstrating the importance of fatty acids and bioactive lipids in health and disease, especially those involving inflammatory disorders or immune dysfunction. If hypertrophic scarring and keloid formation can be argued to have significant inflammatory histories, then it is possible to postulate a role for lipids in their etiology and potentially in their treatment. This report briefly visits past views and theories on keloid formation and treatment, and offers a theoretical rationale for considering adjuvant fatty acid therapy for keloid management. Sufficient scientific evidence in support of fatty acid strategies for the prevention and treatment of keloids currently exists, which offer opportunities to bridge the gap between the laboratory and the clinic. The intent of this paper is to serve as a basic guideline for researchers, nutritionists, and clinicians interested in keloids and to propose new directions for keloid management.

  11. Klein tunneling phenomenon with pair creation process

    Wu, G. Z.; Zhou, C. T.; Fu, L. B.

    2018-01-01

    In this paper, we study the Klein tunneling phenomenon with electron-positron pair creation process. Pairs can be created from the vacuum by a supercritical single-well potential (for electrons). In the time region, the time-dependent growth pattern of the created pairs can be characterized by four distinct regimes which can be considered as four different statuses of the single well. We find that if positrons penetrate the single well by Klein tunneling in different statuses, the total number of the tunneling positrons will be different. If Klein tunneling begins at the initial stage of the first status i.e. when the sing well is empty, the tunneling process and the total number of tunneling positrons are similar to the traditional Klein tunneling case without considering the pair creation process. As the tunneling begins later, the total tunneling positron number increases. The number will finally settle to an asymptotic value when the tunneling begins later than the settling-down time t s of the single well which has been defined in this paper.

    2017-08-01

    One of the adverse effects arising among young people who engage in various social practices is the phenomenon of sexting. Sexting involves the production and delivery of sexual content voluntarily and freely and, in many cases, without the consent of the recipient. The aim of this study was to describe the presence of sexting in undergraduate students at the College of Nursing of the University of Almeria in Spain. It is a descriptive cross-sectional quantitative study. A total of 105 undergraduate nursing students completed the sexuality and technology questionnaire. The questionnaire consists of seven dimensions with 59 items. Depending on size, statistically significant differences between the use of social networks and the dimension "sexting actions completed" and the dimension "position on statements about sexting" were found. No statistically significant differences between gender and the practice of sexting were found. The three main reasons for sexting match in both genders, these being "to draw attention," "as a sexy gift," and "to feel sexy." Nursing students associated behaviors to show sexting, being a standard practice, common in both genders. Future research should consider the possible influence of this behavior on future professionals and on the field of nursing.

    Full Text Available The article is devoted to the problem of outsidership in groups of younger and older adolescents. We assumed that there are personal qualities that distinguish outsiders from other students, which allows us to speak of outsidership as a separate group and personal phenomenon. The study involved 246 students of Moscow schools of younger and older adolescents, 60 of whom took an outsider position in the group. To test the hypothesis were used: a personal questionnaire for adolescents HSPQ (R. Cattell, questionnaire Emin to determine the level of emotional intelligence (D.V. Lyusin, the technique of " Suggestibility " (O.E. Rybakov. To identify statistical differences, the Student's t-test and the Mann-Whitney U-test were used, p ≤ 0.05. The results of the study showed that outsiders of adolescence are indeed characterized by a number of personal characteristics that distinguish them from their peers. Differences in personal characteristics of outsiders at different stages of adolescence have their own characteristics.

  14. Lung tissue mechanics as an emergent phenomenon.

    Suki, Béla; Bates, Jason H T

    2011-04-01

    The mechanical properties of lung parenchymal tissue are both elastic and dissipative, as well as being highly nonlinear. These properties cannot be fully understood, however, in terms of the individual constituents of the tissue. Rather, the mechanical behavior of lung tissue emerges as a macroscopic phenomenon from the interactions of its microscopic components in a way that is neither intuitive nor easily understood. In this review, we first consider the quasi-static mechanical behavior of lung tissue and discuss computational models that show how smooth nonlinear stress-strain behavior can arise through a percolation-like process in which the sequential recruitment of collagen fibers with increasing strain causes them to progressively take over the load-bearing role from elastin. We also show how the concept of percolation can be used to link the pathologic progression of parenchymal disease at the micro scale to physiological symptoms at the macro scale. We then examine the dynamic mechanical behavior of lung tissue, which invokes the notion of tissue resistance. Although usually modeled phenomenologically in terms of collections of springs and dashpots, lung tissue viscoelasticity again can be seen to reflect various types of complex dynamic interactions at the molecular level. Finally, we discuss the inevitability of why lung tissue mechanics need to be complex.

    Full Text Available This research mapped the phenomena that occured in students who are taking classes entrepreneurship that was limited by entrepreneurial knowledge, personal attitude, social norms and self-efficacy. Using descriptive statistics on the answers of 794 respondents, who were students of Bina Nusantara University, produced a variety of results. Based on entrepreneurial knowledge, students still felt hesitant to be able to start and run the entrepreneurial process. On the other hand, self-efficacy and personal attitude reflect a positive thing associated, while the support of family and the environment around where they livevalued invariety. Although this research discovered phenomenon using all the attributes having impacts on entrepreneurship intention, potential students who are properly trained have a probability of playing a leading role in this regard. The benefits that can be expected from this research are useful in identifying suitable students for any entrepreneurial activity in the future with the support of educational institutions, families, and the government as a whole to form the atmosphere of an entrepreneurial culture.

  16. Evolution as a molecular cooperative phenomenon

    Chela-Flores, J.

    1991-06-01

    We discuss an hypothesis according to which microscopic mechanisms due to cooperation, at the molecular level, may have been key factors in the evolution of life on Earth. We view our hypothesis as a natural extension to the molecular level of viewing cooperation (symbiosis) as an evolutionary driving force; this does not restrict the interpretation of the evolutionary process to be the result of slow accumulation of mutations in the DNA. Some evidence supporting this hypothesis is discussed: (a) The Salam enhancement factor. This molecular phenomenon was recently introduced in order to understand the bases of the first unifying principle of biochemistry, namely that transcription of all known genes in prokaryotes, protists, metazoan, and metaphytes are translated into L-amino acids, except for some bacterial membrane proteins. (b) The role that cooperative phenomena may have played in the origin of evolution itself, i.e., in the resolution of Sagan's ultraviolet paradox. (c) The relationship between evolution and the constraints imposed by embryonic development. This is considered from the point of view of molecular cooperative phenomena. (author). Refs

    Vacuum phenomenon was induced inadvertently during radiographic examination of a metatarsophalangeal joint of a lame horse. The phenomenon was recreated in a sound horse when a metacarpophalangeal joint was radiographed in a stress-flexed position. Distraction of apposing articular surfaces may induce the vacuum phenomenon, which could result in misdiagnosis of an osteochondral defect or fracture

    2015-06-01

    Primary Raynaud's phenomenon may be insistent in patients under medical therapy, and intrauterine devices may be an unnoticed reason in these patients. Fluctuations in female sex hormone status were reported to be associated with the emergence of primary Raynaud's phenomenon symptoms. The use of intrauterine devices was not reported to be associated with Raynaud's phenomenon previously. Intrauterine device may stimulate vascular hyperactivity regarding hormonal or unknown mechanisms that result in Raynaud's phenomenon. We present a postmenopausal patient who complained of primary Raynaud's phenomenon symptoms and had recovery after the removal of her copper intrauterine device. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  3. Cognitive approach in studying of entrepreneur phenomenon

    Kulakovsky T.Yu.

    2017-06-01

    Full Text Available The research indicates that there is no prospect of searching specific entrepreneurial traits that are necessary for conducting successful entrepreneurial activity. It is pointed on the impossibility to fully explain the negative state of domestic business exclusively by the influence of environmental factors. The paper points on the necessity of concentrating the scientific search on the cognitive features of personality, as factors that contribute to success of entrepreneurial activities. It is revealed that the decision-making process directed on problem-solving in entrepreneurial activity, from an entrepreneurial idea to obtaining an appropriate result, cannot be algorithmized. The author points out on the insufficiency of attempts to model cognitive processes of entrepreneurs, in which their cognitive activity is regarded as an information processing system that resembles a computer. The results obtained in the framework of the cognitive approach in studying the phenomenon of the entrepreneur are analyzed. Particular emphasis is placed on the features of heuristics and cognitive biases. It is stated that the high levels of uncertainty, novelty, time deficit, information overload and emotional tension facilitate influence of cognitive biases on the cognitive processes of the entrepreneur. The role of «availability heuristic», «anchoring and adjustment heuristic», «confirmation bias», «hindsight bias» and self-efficacy in making decisions about starting an entrepreneurial activity are considered. The article points to the role of «belief in the law of small numbers» and the illusion of control in establishing optimistic bias (overly positive self-esteem, excessive optimism about future plans and events that lead to reducing the subjective perception of entrepreneurial risk.

  4. Electron string phenomenon: physics and use

    Donets, Evgeny D.

    2004-01-01

    Electron string phenomenon arises as a result of phase transition of a state of multiply reflected electron beam to this new discovered state of one component electron plasma and can be easily observed in the reflex mode of EBIS operation. The transition goes via a strong instability, which causes considerable electron energy spread, which in its turn suppresses the instability. Electron string state is a stationary state of hot pure electron plasma, which is heated by injected electron beam and cooled because of electron loses. Electron string is quiet in broad regions of experimental parameters, so that it is used for confinement and ionization of positive ions by electron impact to highly charge states similar to electron beams in EBIS. Application of electron strings instead of electron beams for ion production allows to save about 99% of electric power of electron beam and simultaneously to improve reliability of an ion source considerably. The JINR EBIS `Krion-2' in the string mode of operation is used for production of N7+, Ar16+ and Fe24+ ion beams and their acceleration to relativistic energies on the facility of the JINR super conducting one turn injection synchrotron `Nuklotron'. The tubular electron string possibly can exist and it is under study now theoretically and experiments are prepared now. Estimations show that a Tubular Electron String Ion Source (TESIS) could have up to three orders of magnitude higher ion output then a Linear one (LESIS). In frames of nuclear astrophysics electron strings can be used for research of fusion nuclear reactions at low energies in conditions when both beam and target nuclei do not carry orbital electrons. The project NARITA — Nuclear Astrophysics Researches in an Ion Trap Apparatus is proposed. Polarization effects also can be studied.

    The levels in 162 Gd were identified in spontaneous fission studies. Its transition energies are remarkably similar to those in 160 Gd. From that work, an analysis of yrast bands in even-even proton to neutron-rich Ba to Pb nuclei led to the discovery of a new phenomenon, shifted identical bands (SIB). SIBs are yrast bands in neighboring nuclei (a, b) with moments of inertia which are identical when shifted by a constant amount κ, so J 1a (1 + κ) = J 1b , from 2 + to 8 + and higher to 16 + . Out of over 700 comparisons, 55 SIBs were found from stable to the most neutron-rich Ce-W nuclei with |κ-bar| between 1.5% and 13%, where the spread in κ is less than ± 1%, and only four identical bands (κ-bar congruent with 0). As examples, we found for 158 Sm- 160 Gd, κ-bar (-3.2 +0.1 -0.2 )% (where the ± is the total spread in κ from -3.1 to -3.4); 156 Nd- 160 Gd, (-10.6 +0.4 -0.2 )%; 158 Sm- 160 Sm, (3.4 +0.5 -0.3 )%. The J 1 values were fitted to a variable moment of inertia model with parameters J 0 and C whose values correlate with the SIB J 1 values. The SIBs are not correlated either with deformation or with the N p N n product of the IBA model

    2016-02-01

    Despite strong indications of a high prevalence of weight-related stigmatization in individuals with obesity, limited attention has been given to the role of weight discrimination in examining the stigma obesity. Studies, up to date, rely on a limited basis of data sets and additional studies are needed to confirm the findings of previous studies. In particular, data for Europe are lacking, and are needed in light of a recent ruling of the European Court of Justice that addressed weight-based discrimination. The data were derived from a large representative telephone survey in Germany (n=3003). The dependent variable, weight-based discrimination, was assessed with a one-item question. The lifetime prevalence of weight discrimination across different sociodemographic variables was determined. Logistic regression models were used to assess the association of independent and dependent variables. A sub-group analysis was conducted analyzing all participants with a body mass index ⩾25 kg m(-)(2). The overall prevalence of weight-based discrimination was 7.3%. Large differences, however, were observed regarding weight status. In normal weight and overweight participants the prevalence was 5.6%, but this number doubled in participants with obesity class I (10.2%), and quadrupled in participants with obesity class II (18.7%) and underweight (19.7%). In participants with obesity class III, every third participant reported accounts of weight-based discrimination (38%). In regression models, after adjustment, the associations of weight status and female gender (odds ratio: 2.59, PDiscrimination seems to be an ubiquitary phenomenon at least for some groups that are at special risk, such as heavier individuals and women. Our findings therefore emphasize the need for research and intervention on weight discrimination among adults with obesity, including anti-discrimination legislation.

  8. The Trump phenomenon: An explanation from sociophysics

    Galam, Serge

    2017-04-01

    The Trump phenomenon is argued to depart from current populist rise in Europe. According to a model of opinion dynamics from sociophysics the machinery of Trump’s amazing success obeys well-defined counter-intuitive rules. Therefore, his success was in principle predictable from the start. The model uses local majority rule arguments and obeys a threshold dynamics. The associated tipping points are found to depend on the leading collective beliefs, cognitive biases and prejudices of the social group which undertakes the public debate. And here comes the open sesame of the Trump campaign, which develops along two successive steps. During a first moment, Trump’s statement produces a majority of voters against him. But at the same time, according to the model the shocking character of the statement modifies the prejudice balance. In case the prejudice is present even being frozen among voters, the tipping point is lowered at Trump’s benefit. Nevertheless, although the tipping point has been lowered by the activation of frozen prejudices it is instrumental to preserve enough support from openly prejudiced people to be above the threshold. Then, as infuriated voters launch intense debate, occurrence of ties will drive progressively hostile people to shift their voting intention without needing to endorse the statement which has infuriated them. The ongoing debate does drive towards a majority for Trump. The possible Trump victory at November Presidential election is discussed. In particular, the model shows that to eventually win the Presidential election, Trump must not modify his past shocking attitude but to appeal to a different spectrum of frozen prejudices, which are common to both Democrats and Republicans.

  10. Greenhouse Gases Emission and Global Warming Potential as Affected by Chemical Inputs for Main Cultivated Crops in Kerman Province: - Horticultural Crops

    Nasibe Pourghasemian

    2017-12-01

    Full Text Available Introduction The latest report of the IPCC states that future emissions of greenhouse gases (GHGs will continue to increase and will be the main cause of global climatic changes, as well as Iran. The three greenhouse gases associated with agriculture are CO2, CH4, and N2O. Chemical inputs consumption in agriculture has increased annually, while more intensive use of energy led to some important human health and environmental problems such as greenhouse gas emissions and global warming. Therefore, it is necessary to reduce the application of chemical inputs in agricultural systems. Agriculture contributes significantly to atmospheric GHG emissions, with 14% of the global net CO2 emissions coming from this sector. Chemical inputs have a major role in this hazards. There is even less data on CO2, N2O, and CH4 gas emission analysis as affected by cultivating various crops in Kerman province. Therefore, this study was conducted to assess the GHGs emission and Global warming Potential GWP caused by chemical inputs (various chemical fertilizers and pesticides for cultivating potato, onion and watermelon in some regions of Kerman province at 2011-2012 growth season. Material and Methods The study was conducted in Kerman province of Iran. Data of planting area, application rates of the chemical inputs and other different parameter were collected from potato, onion and watermelon growers by using a face to face questionnaire in 2014 for different regions of Kerman(Bardsir, Bam, Jiroft, Kerman, Ravar, Rafsanjan and Sirjan. In addition to the data obtained by surveys, previous studies of related organization (Agricultural Ministry of Kerman were also utilized during the study. Farm random sampling was done within whole population and the sample size was determined by proper equations. The amounts of GHG emissions from chemical inputs in the studied crops were calculated by using CO2, N2O and CH4 emissions coefficient of chemical inputs. Then the amount of

  14. The Electrophysiological Phenomenon of Alzheimer's Disease: A Psychopathology Theory.

    Holston, Ezra C

    2015-08-01

    The current understanding of Alzheimer's disease (AD) is based on the Aβ and tau pathology and the resulting neuropathological changes, which are associated with manifested clinical symptoms. However, electrophysiological brain changes may provide a more expansive understanding of AD. Hence, the objective of this systematic review is to propose a theory about the electrophysiological phenomenon of Alzheimer's disease (EPAD). The review of literature resulted from an extensive search of PubMed and MEDLINE databases. One-hundred articles were purposively selected. They provided an understanding of the concepts establishing the theory of EPAD (neuropathological changes, neurochemical changes, metabolic changes, and electrophysiological brain changes). Changes in the electrophysiology of the brain are foundational to the association or interaction of the concepts. Building on Berger's Psychophysical Model, it is evident that electrophysiological brain changes occur and affect cortical areas to generate or manifest symptoms from onset and across the stages of AD, which may be prior to pathological changes. Therefore, the interaction of the concepts demonstrates how the psychopathology results from affected electrophysiology of the brain. The theory of the EPAD provides a theoretical foundation for appropriate measurements of AD without dependence on neuropathological changes. Future research is warranted to further test this theory. Ultimately, this theory contributes to existing knowledge because it shows how electrophysiological changes are useful in understanding the risk and progression of AD across the stages.

  15. Powerful Radio Burst Indicates New Astronomical Phenomenon

    2007-09-01

    Astronomers studying archival data from an Australian radio telescope have discovered a powerful, short-lived burst of radio waves that they say indicates an entirely new type of astronomical phenomenon. Region of Strong Radio Burst Visible-light (negative greyscale) and radio (contours) image of Small Magellanic Cloud and area where burst originated. CREDIT: Lorimer et al., NRAO/AUI/NSF Click on image for high-resolution file ( 114 KB) "This burst appears to have originated from the distant Universe and may have been produced by an exotic event such as the collision of two neutron stars or the death throes of an evaporating black hole," said Duncan Lorimer, Assistant Professor of Physics at West Virginia University (WVU) and the National Radio Astronomy Observatory (NRAO). The research team led by Lorimer consists of Matthew Bailes of Swinburne University in Australia, Maura McLaughlin of WVU and NRAO, David Narkevic of WVU, and Fronefield Crawford of Franklin and Marshall College in Lancaster, Pennsylvania. The astronomers announced their findings in the September 27 issue of the online journal Science Express. The startling discovery came as WVU undergraduate student David Narkevic re-analyzed data from observations of the Small Magellanic Cloud made by the 210-foot Parkes radio telescope in Australia. The data came from a survey of the Magellanic Clouds that included 480 hours of observations. "This survey had sought to discover new pulsars, and the data already had been searched for the type of pulsating signals they produce," Lorimer said. "We re-examined the data, looking for bursts that, unlike the usual ones from pulsars, are not periodic," he added. The survey had covered the Magellanic Clouds, a pair of small galaxies in orbit around our own Milky Way Galaxy. Some 200,000 light-years from Earth, the Magellanic Clouds are prominent features in the Southern sky. Ironically, the new discovery is not part of these galaxies, but rather is much more distant

  18. How much might additional half a degree from a global warming of 1.5°C affects the extreme precipitation change in China?

    Li, W.; Jiang, Z.

    2017-12-01

    In order to strengthen the global respond to the dangerous of global warming, Paris Agreement sets out two long-term warming goals: limiting global warming to well below 2˚C and purse effort to below 1.5˚C above pre-industrial levels. However, future climate change risks in those two warming targets show significant regional differences. This article aims to study the intensity and frequency of extreme precipitation change over China under those two global warming targets by using CMIP5 models under RCP4.5 and RCP8.5 scenario. Focus is put on the effects of the additional half degree in changing the extreme precipitation. Results show that the changes of extreme precipitation are independent of the RCP scenarios when global warming reaches the same threshold. Intensity of extreme precipitation averaged over China increase by around 6% and 11% when global warming reaches 1.5˚C and 2˚C, respectively. The additional half a degree increase makes the intensity of extreme precipitation averaged over China to increase by 4.5%, which translates to an increase close to the Clausius-Clapeyron scaling. Return period decreases by 5 years for the extra half degree warming when the 20-year return values are considered at the reference level.

    1987-01-01

    The paramedian diencephalic syndrome is characterized by a clinical triad: hypersomnolent apathy, amnesic syndrome, and impaired vertical gaze. We studied 4 cases with computed tomography evidence of bilateral diencephalic infarctions. Each case began abruptly with hypersomnolent apathy followed by fluctuations from appropriate affect, full orientation, and alertness to labile mood, confabulation, and apathy. Speech varied from hypophonia to normal; handwriting varied from legible script to gross scrawl. Psychological testing revealed poor learning and recall, with low performance scores. In 3 patients the predominant abnormality was in downward gaze.

  2. Forced Migration and Global Responsibility for Health

    Bozorgmehr, Kayvan; Razum, Oliver

    2017-01-01

    Forced migration has become a world-wide phenomenon in the past century, affecting increasing numbers of countries and people. It entails important challenges from a global health perspective. Leppold et al have critically discussed the Japanese interpretation of global responsibility for health in the context of forced migration. This commentary complements their analysis by outlining three priority areas of global health responsibility for European Union (EU) countries. We highlight important stages of the migration phases related to forced migration and propose three arguments. First, the chronic neglect of the large number of internally displaced persons (IDPs) in the discourses on the "refugee crisis" needs to be corrected in order to develop sustainable solutions with a framework of the Sustainable Development Goals (SDGs). Second, protection gaps in the global system of protection need to be effectively closed to resolve conflicts with border management and normative global health frameworks. Third, effective policies need to be developed and implemented to meet the health and humanitarian needs of forced migrants; at the same time, the solidarity crisis within the EU needs to be overcome. These stakes are high. EU countries, being committed to global health, should urgently address these areas. PMID:28812838

  3. MOVIE INDUCED TOURISM: A NEW TOURISM PHENOMENON

    Mijalce Gjorgievski

    2012-06-01

    Full Text Available At the turn of the century, the tourism industry underwent a transformation triggered by the sweeping processes of globalization. The traditional forms of tourism were supplemented and expanded by the introduction of new postmodern tourist forms, bringing new and different tourist offers to the marketplace. One of these new forms is the film tourism, a rapidly growing and important new tourism trend, in which the choice of the tourist destination is directly motivated and inspired by the movies. Film tourism establishes a link between the movie characters, locations and stories, and the film-tourists, who are inspired to immerse themselves and relive again the movie-generated and movie-driven emotions at the location of the movie. The film tourism increases the overall economic effects of tourism and establishes a new link between the film and the tourism industry, both of which provide not only pleasure and satisfaction for the film tourist, but also spiritual enrichment and novel learning experience.

  4. Firm Size, a Self-Organized Critical Phenomenon: Evidence from the Dynamical Systems Theory

    Chandra, Akhilesh

    This research draws upon a recent innovation in the dynamical systems literature called the theory of self -organized criticality (SOC) (Bak, Tang, and Wiesenfeld 1988) to develop a computational model of a firm's size by relating its internal and the external sub-systems. As a holistic paradigm, the theory of SOC implies that a firm as a composite system of many degrees of freedom naturally evolves to a critical state in which a minor event starts a chain reaction that can affect either a part or the system as a whole. Thus, the global features of a firm cannot be understood by analyzing its individual parts separately. The causal framework builds upon a constant capital resource to support a volume of production at the existing level of efficiency. The critical size is defined as the production level at which the average product of a firm's factors of production attains its maximum value. The non -linearity is inferred by a change in the nature of relations at the border of criticality, between size and the two performance variables, viz., the operating efficiency and the financial efficiency. The effect of breaching the critical size is examined on the stock price reactions. Consistent with the theory of SOC, it is hypothesized that the temporal response of a firm breaching the level of critical size should behave as a flicker noise (1/f) process. The flicker noise is characterized by correlations extended over a wide range of time scales, indicating some sort of cooperative effect among a firm's degrees of freedom. It is further hypothesized that a firm's size evolves to a spatial structure with scale-invariant, self-similar (fractal) properties. The system is said to be self-organized inasmuch as it naturally evolves to the state of criticality without any detailed specifications of the initial conditions. In this respect, the critical state is an attractor of the firm's dynamics. Another set of hypotheses examines the relations between the size and the

  5. Moe fenomen. The Phenomenon of Fashion

    Ines Piibeleht

    2012-06-01

    Full Text Available Since the last quarter of the 20th century, particularly after the “cultural turn”, the interest in fashion has been increasing in a variety of different disciplines. Fashion has begun to be investigated in many different contexts, using new theoretical approaches. Fashion can be regarded as a social phenomenon, a sign system, as art, myth, or the product of the fashion industry. The purpose of this article is not to provide a definition of fashion, but rather to raise the question of how to approach the experience of fashion analytically. The methodological issues discussed here emerged in the course of preparing for empirical research on fashion. The observations and comparisons that constitute the core of this article are the result of efforts to juxtapose different methods. The traditional history of fashion used a historical-epistemological strategy but, depending on how one defines culture, the meaning of fashion can also be analysed using methods based on different epistemological strategies. The phenomenological method elaborated by Edmund Husserl, which I have chosen for my analysis of the experience of fashion, defines culture through the experiential acts of individuals. Simply stated, phenomenology considers the world as it is given to us in our consciousness. What is most important for empirical research is that the phenomenological method makes it possible to study the structure of a concrete experience and to focus on the mechanisms of the subjective creation of meaning. Thus this article has two main foci: a theoretical analysis of how the experience of fashion can be analytically revealed using the phenomenological method, and a comparison of the phenomenological approach with methods based on other strategies.

    2017-10-01

    Full Text Available Introduction Agriculture is a major consumer of chemical resources. Increasing use of the inputs in agriculture has led to numerous environmental problems such as high consumption of nonrenewable energy resources, loss of biodiversity and pollution of the aquatic environment (Moradi et al., 2014. This environmental change will have the serious impacts on different growth and development processes of crops. The latest report of the Intergovernmental Panel on Climate Change (IPCC states that future emissions of greenhouse gases (GHGs will continue to increase and cause to climatic change (IPCC, 2007. This condition is also true for Iran. The three greenhouse gases associated with agriculture are carbon dioxide (CO2, methane (CH4, and nitrous oxide (N2O. Consistent with the development of agricultural production systems and move towards modernization in this sector increased dependence of the chemical resource (Salinger, 2005. There is even less data on CO2, N2O, and CH4 gas emission analysis as affected by cultivating various crops in Kerman province. Therefore, this study was conducted to assess the greenhouse gases (GHGs emission and global warming potential (GWP caused by chemical inputs (various chemical fertilizers and pesticides for cultivating wheat, barley and maize in some regions of Kerman province at 2011-2012 growth season. Materials and methods The study was conducted in Kerman province of Iran. Information about planting area of potato, onion and watermelon in various regions of Kerman was collected. Data were collected from potato, onion and watermelon growers by using a face to face questionnaire in 2014 for different regions of Kerman. In addition to the data obtained by surveys, previous studies of related organization (Agricultural Ministry of Kerman were also utilized during the study. The application rates of the chemical inputs were collected by using a face-to-face questionnaire in various regions (Bardsir, Bam, Jiroft

    Full Text Available We describe a 59-year-old female who presented with ischaemic digits, preceded by a 6-month history of Raynaud’s phenomenon affecting her fingers and toes. There were no clinical or laboratory features of primary vasculitis or connective tissue disease, Doppler imaging was normal, and bloods were unremarkable aside from a platelet count of 786 × 109/L (150–400 and white cells of 16 × 109/L (4–11. In view of the thrombocytosis a JAK2 mutation assay was requested which confirmed a JAK2 V617F mutation, suggesting essential thrombocytosis (ET as the cause. She received treatment with hydroxycarbamide which normalised her platelet count and led to a complete resolution of her Raynaud’s symptoms. Raynaud’s phenomenon is a rare manifestation of ET. Myeloproliferative disorders such as ET should be considered in the differential diagnosis of Raynaud’s phenomenon and vasculitis.

    2016-12-01

    Full Text Available This sociolinguistics study investigates a new phenomenon that has recently surfaced in the field of code-switching among Saudi females residing in the Western region of Saudi Arabia. This phenomenon basically combines bound Arabic pronouns, tense markers or definite article to English free morphemes or the combination of bound English affixes to Arabic morphemes. Moreover, the study examines the factors that affect this type of code-switching. The results of the study indicate that this phenomenon provides data that invalidates Poplack’s (1980 universality of the ‘Free Morpheme Constraint’. It is also concluded that the main factors that influence this type of code-switching is solidarity and group identity among other factors.

  10. Does eye tremor provide the hyperacuity phenomenon?

    Zozor, Steeve; Amblard, Pierre-Olivier; Duchêne, Cédric

    2009-01-01

    This paper is devoted to a study of the role of the fluctuations that the eye is subject to, from the point of view of noise-enhanced processing. To this end, a basic model of the retina is considered, namely a regular sampler subject to space and time fluctuations that model the random sampling and the involuntary eye tremor respectively. The filtering that can be done by the photoreceptor is also taken into account and the study focuses on a stochastic model of a natural scene. To quantify the effect of the noise, a coefficient of correlation between the signal acquired by a given photoreceptor and a given point of the scene that the eye is looking at is considered. It is shown both for academic examples and for a more realistic case that the fluctuations which affect the retina can induce noise-enhanced processing effects. The observed effect is then interpreted as a stochastic control of the retina via the random tremor

  15. The Female Athlete Triad: A Metabolic Phenomenon

    Anne B. Loucks

    2014-06-01

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE The Female Athlete Triad (Triad is a syndrome in which low energy availability triggers a broad range of endocrine mechanisms that conserve energy expenditure, and thereby impairs reproductive and skeletal health.  Energy availability is the amount of dietary energy remaining after exercise training for all other physiological functions each day.  The specific kind of reproductive dysfunctions caused by low energy availability are functional hypothalamic menstrual disorders.  To ensure that affected athletes receive appropriate care, endocrine tests are required to diagnose these disorders by the exclusion of other types of menstrual disorders unrelated to the Triad.  In addition, low energy availability impairs skeletal health by uncoupling bone turnover, in which the rate of bone resorption increases while the rate of bone formation declines.  The result is a progressive loss or failure to accrue bone mass, which increases the risks of stress fractures and osteoporosis.  Low energy availability originates in one or more of three sources:  restrictive eating disorders, especially anorexia nervosa; intentional efforts to lose body weight or body fat to improve athletic performance or appearance; and the inadvertent suppression of appetite by exercise and diets containing a high percentage of carbohydrates.  It is necessary to know the origin of low energy availability in a particular athlete in order to intervene effectively with her.  The key behavior modification for preventing and treating the Triad is to increase energy availability, either by increasing dietary energy intake, reducing exercise energy expenditure, or both.  Guidelines for doing so are provided. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5

  17. Sidoarjo mudflow phenomenon and its mitigation efforts

    Wibowo, H. T.; Williams, V.

    2009-12-01

    Hot mud first erupted in Siring village, Porong, Sidoarjo May 29th 2006. The mud first appeared approximately 200 meters from Banjarpanji-1 gas-drilling well. The mud volume increased day by day, from 5000 cubic meters per day on June 2006 to 50,000 cubic meters per day during the last of 2006, and then increased to 100,000-120,000 cubic meters per day during 2007. Flow still continues at a high rate. Moreover, as the water content has gone down, the clast content has gone up. Consequently, there is now the threat of large amounts of solid material being erupted throughout the area. Also, there is the issue of subsurface collapse and ground surface subsidence. The Indonesian government has set up a permanent team to support communities affected by the mudflow that has swamped a number of villages near LUSI. Toll roads, railway tracks and factories also have been submerged and over 35,000 people have been displaced to date. The Sidoarjo Mudflow Mitigation Agency [SMMA, BPLS (Indonesia)] replaces a temporary team called National Team PSLS which was installed for seven months and ended their work on 7 April 2007. BPLS was set up by Presidential Regulation No. 14 / 2007, and it will have to cover the costs related to the social impact of the disaster, especially outside the swamped area. BPLS is the central government institution designated to handle the disaster by coordination with both the drilling company and local (provincial and district) governments. It takes a comprehensive, integrated and holistic approach for its mission and challenges. Those are: 1) How to stop the mudflow, 2) How to mitigate the impacts of the mudflow, and 3) How to minimize the social, economic, environmental impacts, and infrastructure impacts. The mudflow mitigation efforts were constrained by dynamic geology conditions, as well as resistance to certain measures by residents of impacted areas. Giant dykes were built to retain the spreading mud, and the mudflow from the main vent was

  19. An investigation for identification of factors governing F and P phenomenon

    Ray, M.K.S.; Saini, R.D.; Kutty, K.K.; Das, D.

    1992-01-01

    A series of experiments were carried out in divided electrolytic cells in an attempt to identify factors governing the occurence of Fleischmann and Pons (F and P) phenomenon. Despite wide variation in operating parameters (cathode characteristics, type and concentration of electrolyte) and perturbation of deuterated cathodes and sharp change in their temperatures, experiments yielded no evidence of the phenomenon even though high loading (sometimes upto D/Pd ∼2) could be achieved repeatedely. However, large excess heat liberation, not accountable by probable physicochemical processes, was observed following perturbation of the state of equilibrium of a deuterated cathode (having a portion of it free of scale and bright in appearance) by air. Instances of anomalies in tritium distribution between gas and liquid phase resulting from such perturbation were also noticed. These observations, when analysed in global perspective, clearly indicate the essentiality of oxygen and scale free surface for occurrence of the phenomenon. Study of desorption dynamics and related parameters revealed that the overall effect of oxygen is to enhance the escaping tendency of deuterium from Pd lattice and that the phenomenon is in someway related to desorption. Significant increase in tritium activity in gas phase observed following repeated perturbation of deuterated cathode by induced pulsed magnetic field is suggestive of a possible mechanism in which strong electron affinity of oxygen is of paramount importance.

  20. Even at the uttermost ends of the Earth: how seabirds telecouple the Beagle Channel with regional and global processes that affect environmental conservation and social-ecological sustainability

    Andrea N. Raya Rey

    2017-12-01

    Full Text Available Human-wildlife dynamics exhibit novel characteristics in the Anthropocene, given the unprecedented degree of globalization that has increased the linkages between habitats and people across space and time. This is largely caused by transnational mobility and migration, international labor, resource markets, and trade. Understanding the relationship between humans and wildlife, and their associated telecoupling processes, helps to promote better management practices and governance for reconciling socioeconomic and conservation interests. Even remote places on the globe exhibit these features. For example, in southern Patagonia's coastal and marine ecosystems, seabirds are not only very abundant and charismatic members of the wildlife community, nowadays, their colonies are a main tourism attraction of global significance, and in the past they were used for consumptive and scientific purposes that also linked the "uttermost ends of the Earth" with distant places. Thus, in this study, we review human-seabird interactions in the iconic Beagle Channel (BC in the Argentine portion of the Tierra del Fuego Archipelago. We adapted and employed the coupled human and natural systems (CHANS approach and telecoupling framework to integrate disparate social and biological information and obtain a more holistic understanding of current human-seabird dynamics and trends in the BC. Although our assessment includes the temporal scale of human-seabird relationships, we centered the CHANS and telecoupling analysis on the modern seabird-tourism interaction, focused on the channel's Argentine sector, in which tourism is most intensively developed. Our synthesis of the BC's telecoupled CHANS allowed us to recognize the strong historical local-to-global interactions between both human and natural subsystems and the sharp increase in distance telecoupling during the 20th century. Despite this globalizing trend in seabirds connecting the BC's local ecosystems to distant

  3. Global scene layout modulates contextual learning in change detection.

    Conci, Markus; Müller, Hermann J

    2014-01-01

    Change in the visual scene often goes unnoticed - a phenomenon referred to as "change blindness." This study examined whether the hierarchical structure, i.e., the global-local layout of a scene can influence performance in a one-shot change detection paradigm. To this end, natural scenes of a laid breakfast table were presented, and observers were asked to locate the onset of a new local object. Importantly, the global structure of the scene was manipulated by varying the relations among objects in the scene layouts. The very same items were either presented as global-congruent (typical) layouts or as global-incongruent (random) arrangements. Change blindness was less severe for congruent than for incongruent displays, and this congruency benefit increased with the duration of the experiment. These findings show that global layouts are learned, supporting detection of local changes with enhanced efficiency. However, performance was not affected by scene congruency in a subsequent control experiment that required observers to localize a static discontinuity (i.e., an object that was missing from the repeated layouts). Our results thus show that learning of the global layout is particularly linked to the local objects. Taken together, our results reveal an effect of "global precedence" in natural scenes. We suggest that relational properties within the hierarchy of a natural scene are governed, in particular, by global image analysis, reducing change blindness for local objects through scene learning.

    2013-04-15

    There has been a theoretical debate as to which retrospective record review method is the most valid, reliable, cost efficient and feasible for detecting adverse events. The aim of the present study was to evaluate the feasibility and capability of two common retrospective record review methods, the "Harvard Medical Practice Study" method and the "Global Trigger Tool" in detecting adverse events in adult orthopaedic inpatients. We performed a three-stage structured retrospective record review process in a random sample of 350 orthopaedic admissions during 2009 at a Swedish university hospital. Two teams comprised each of a registered nurse and two physicians were assigned, one to each method. All records were primarily reviewed by registered nurses. Records containing a potential adverse event were forwarded to physicians for review in stage 2. Physicians made an independent review regarding, for example, healthcare causation, preventability and severity. In the third review stage all adverse events that were found with the two methods together were compared and all discrepancies after review stage 2 were analysed. Events that had not been identified by one of the methods in the first two review stages were reviewed by the respective physicians. Altogether, 160 different adverse events were identified in 105 (30.0%) of the 350 records with both methods combined. The "Harvard Medical Practice Study" method identified 155 of the 160 (96.9%, 95% CI: 92.9-99.0) adverse events in 104 (29.7%) records compared with 137 (85.6%, 95% CI: 79.2-90.7) adverse events in 98 (28.0%) records using the "Global Trigger Tool". Adverse events "causing harm without permanent disability" accounted for most of the observed difference. The overall positive predictive value for criteria and triggers using the "Harvard Medical Practice Study" method and the "Global Trigger Tool" was 40.3% and 30.4%, respectively. More adverse events were identified using the "Harvard Medical Practice Study

  11. Repressing the Foreign Fighters Phenomenon in Western Europe: Towards an Effective Response Based on Human Rights

    Christophe Paulussen

    2016-11-01

    Full Text Available This Research Paper explores how the foreign fighters phenomenon and terrorism more generally is repressed in Western Europe. It looks at a few specific repressive measures announced or adopted by France and the Netherlands, as well as criticism expressed against these proposals and measures. In addition to these two detailed analyses, references will also be made to other developments in Western Europe which appear to be indicative of a more general trend in which human rights increasingly seem to be put on the back seat when countering the phenomenon of foreign fighters and terrorism more generally. In the final section, a number of concluding thoughts and recommendations will be offered which explain why only a response based on human rights will be effective in countering this global problem in the long run.

  12. Less approach, more avoidance: Response inhibition has motivational consequences for sexual stimuli that reflect changes in affective value not a lingering global brake on behavior.

    Driscoll, Rachel L; de Launay, Keelia Quinn; Fenske, Mark J

    2018-02-01

    Response inhibition negatively impacts subsequent hedonic evaluations of motivationally relevant stimuli and reduces the behavioral incentive to seek and obtain such items. Here we expand the investigation of the motivational consequences of inhibition by presenting sexually appealing and nonappealing images in a go/no-go task and a subsequent image-viewing task. Each initially obscured image in the viewing task could either be made more visible or less visible by repeatedly pressing different keys. Fewer key presses were made to obtain better views of preferred-sex images when such images had previously been inhibited as no-go items than when previously encountered as noninhibited go items. This finding replicates prior results and is consistent with the possibility that motor-response suppression has lingering effects that include global reductions in all behavioral expression. However, for nonpreferred images, prior inhibition resulted in more key presses to obscure their visibility than when such images had not been inhibited. This novel finding suggests that the motivational consequences of response inhibition are not due to a global brake on action but are instead linked to negative changes in stimulus value that induce corresponding increases in avoidance and decreases in approach.

The stage of gallbladder opacification in the recumbent position has been classified as (I) mottled, (II) dendritic, (III) ring-like, and (IV) homogeneous. 'Dendritic' type of stratification phenomenon has never been reported in the literature to our knowledge. At 20 min following infusion of contrast material homogeneous opacification of the gallbladder was noticed in only 14% of patients. The others fell into types I, II or III of stratification phenomenon. In contrast, 87% of the opacified gallbladders were homogeneous on the after fatty meal film. It is therefore mandatory for diagnosis that either a 24 h film or a fatty meal film be taken to avoid the stratification phenomenon.

This represents, probably, the main reason why the research on migration is interdisciplinary, having strong connections with sociology, political sciences, history, economics, geography, demography, psychology, or low, among others. All these disciplines target different aspects of population migration, and a proper comprehension of the phenomenon implies a contribution from the part of all of them. Although migration represents a phenomenon manifested since ancient times, it has never been such an universal or significant phenomenon from the socio-economical or political perspective, as it is in present times. International migration has both a negative and positive impact on both provider and receiving countries, in general playing a very important role in the structure and dimension of the population of a country. Romania is not an exception to the previously expressed statement; furthermore, after the fall of the communist regime, migration became for Romania one of the most important socio-economical phenomena. The present paper aims at analyzing in a descriptive manner the international migration phenomenon in Romania between 1991 and 2008, from quantitative perspective. Based on data identified in the "Statistical Yearbook of Romania - 2008 and 2009 editions - the analysis revealed the fact that both immigration and emigration flows registered oscillatory evolutions in the analysed period, but the general trend of immigration was of increasing, while the one of emigration was of decreasing. Immigration was dominated by the presence of males, of persons aged between 26 and 40 and of persons coming from the Republic of Moldova. On the other side, in the case of emigration the significant

    The diagnostic value of the vacuum phenomenon between the femoral head and the acetabulum, and time frame of its occurrence after application of traction is an important clinical question. The resulting arthrogram may outline the shape, location, and extent of cartilage lesions prior to arthroscopy of the hip joint. The presence, duration, and diagnostic information of the vacuum phenomenon were evaluated in 24 hips that underwent arthroscopy. The operative diagnosis was compared to the results of imaging studies and to findings obtained during a traction trial prior to arthroscopy. Indications for arthroscopy included avascular necrosis, labral tears, loose bodies, osteoarthrosis, and intractable hip pain. In 22 hips the vacuum phenomenon developed within 30 seconds after application of traction. The most important data obtained from the vacuum phenomenon was the location and extent of femoral head articular cartilage detachment and the presence of nonossified loose bodies. The vacuum phenomenon did not reveal labral or acetabular cartilage pathology in any of these patients. The vacuum phenomenon obtained during the trial of traction can add valuable information prior to hip arthroscopy. Femoral head articular cartilage detachment was best documented by this method. The hip arthroscopist should utilize this diagnostic window routinely prior to hip arthroscopy. PMID:24977068

    Full Text Available The purpose of the investigation was to study the clinical value of the deja vu phenomenon in healthy examinees as it may occur in healthy individuals, on the one hand, and is a symptom of a number of psychoneurological diseases, on the other. One hundred and twenty-nine subjects, mean age 25,2±4,4 years, were examined. All the examinees were questioned by the original questionnaire developed by the authors, which was to reveal the characteristics of the phenomenon, and the Cambridge depersonalization questionnaire; standard electroencephalography was also performed. The deja vu phenomenon was detected in 97% of the respondents. In healthy individuals, the phenomenon was most common at the age of 21-25 years; 52,2% experienced deja vu several times a year; 64,5% of the respondents reported the 10-sec state; 85% did not associate the occurrence of the phenomenon with any provoking factor; 66% perceived deja vu with a positive emotional tinge, and only 4% of the respondents were afraid of the onset of this phenomenon. These criteria may be used to rule out pathological deja vu

  6. Distinct mutations in yeast TAF(II)25 differentially affect the composition of TFIID and SAGA complexes as well as global gene expression patterns.

    The RNA polymerase II transcription factor TFIID, composed of the TATA-binding protein (TBP) and TBP-associated factors (TAF(II)s), nucleates preinitiation complex formation at protein-coding gene promoters. SAGA, a second TAF(II)-containing multiprotein complex, is involved in transcription regulation in Saccharomyces cerevisiae. One of the essential protein components common to SAGA and TFIID is yTAF(II)25. We define a minimal evolutionarily conserved 91-amino-acid region of TAF(II)25 containing a histone fold domain that is necessary and sufficient for growth in vivo. Different temperature-sensitive mutations of yTAF(II)25 or chimeras with the human homologue TAF(II)30 arrested cell growth at either the G(1) or G(2)/M cell cycle phase and displayed distinct phenotypic changes and gene expression patterns. Immunoprecipitation studies revealed that TAF(II)25 mutation-dependent gene expression and phenotypic changes correlated at least partially with the integrity of SAGA and TFIID. Genome-wide expression analysis revealed that the five TAF(II)25 temperature-sensitive mutant alleles individually affect the expression of between 18 and 33% of genes, whereas taken together they affect 64% of all class II genes. Thus, different yTAF(II)25 mutations induce distinct phenotypes and affect the regulation of different subsets of genes, demonstrating that no individual TAF(II) mutant allele reflects the full range of its normal functions.

    LIVIU RADU

    2011-04-01

    Full Text Available Globalization represents a myriad of processes of undeniable complexity and variable dynamics, which cover various society areas. It can depict various aspects of phenomenon, ideology, strategy, or all in one place. Globalization is with no doubt a complex concept that bears diverse significations which refer to many sides: the economical, the political, the cultural one etc. Most authors view as particularly important the economic side of globalization, while they seem to be looking over the political, social or cultural aspects of this phenomenon. Thus the optimists view contemporary globalization as a new phase in which all the world’s states are subjected to sanctions from the global market, while skeptics argue that the globalization phenomenon determines chain reactions, incontrollable here and there, in conditions of a present crisis, precisely through the interdependency between states.

  10. Phenomenon of transforming love in the works of F.М. Dostoyevsky

    A. M. Shatalovich

    2013-12-01

    Full Text Available The article revealed contents of the phenomenon of transforming love in the work of Dostoevsky on the materials of the novel «The Idiot». Many philosophic studies were devoted to the problem of analysis of the phenomenon of love in the works of F.M. Dostoyevsky. Most researchers emphasize the sacrificial (agapic love, or focuses on erotic nature of love. This approach significantly constricts the phenomenon of love described by the writer in the form of Prince Myshkin. The study of love of Prince was carried out using four concepts covering the four key aspects of love: eros, agape, philia and storge. Thus, there are main features of love­eros of Prince Myshkin, such as: drive for beauty and its admiration, ardor and impetuosity, recklessness and frenzy, which are positive, i.e. they are the evidence that his love­eros was hierarchically focused on more exalted goods. Love­agape is in the center of the phenomenon of transforming love with its pity, compassion, sacrifice, care and forgiveness. Love­philia is demonstrated in Prince Myshkin by similarity of views, common ground, mutual understanding, trust and love­storge – by affection causing peace of mind or depression. Thus, the study proved that Prince Myshkin is an ideologist of transforming love, combining all four aspects of it. Creativity, the ability to change spiritually not only the love medium but also the people around is the evidence of his transforming love.

    Zonal disintegration phenomenon was found in deep mining roadway surrounding rock. It seriously affects the safety of mining and underground engineering and it may lead to the occurrence of natural disasters. in deep mining roadway surrounding rock, tectonic stress in deep mining roadway rock mass, horizontal stress is much greater than the vertical stress, When the direction of maximum principal stress is parallel to the axis of the roadway in deep mining, this is the main reasons for Zonal disintegration phenomenon. Using ABAQUS software to numerical simulation of the three-dimensional model of roadway rupture formation process systematically, and the study shows that when The Direction of maximum main stress in deep underground mining is along the roadway axial direction, Zonal disintegration phenomenon in deep underground mining is successfully reproduced by our numerical simulation..numerical simulation shows that using ABAQUA simulation can reproduce Zonal disintegration phenomenon and the formation process of damage of surrounding rock can be reproduced. which have important engineering practical significance.

  12. The Phenomenon of Touch in Architectural Design and a Field Study on Haptic Mapping

    Pınar ÖKTEM ERKARTAL

    2015-02-01

    Full Text Available Ocular-centrism is the utilitarian-aesthetic perspective which dominates the perception of spatial quality and architectural success in the West. In locating vision as the dominant discourse in architectural design, this perspective has been criticized for ignoring the physical and psychological relation created between subject and space during the spatial experience, sensual memory, movement and time. The phenomenon of touch, which may be defined as the interaction between architecture and subject dependent on physical and cognitive perception, offers another way of thinking and interpreting architecture, and constitutes an alternative starting point for design. The aim of this study was three-fold: to research and describe the phenomenon of touch in design concepts, to present the effects of hapticity in spatial experience on the user, and to present a visualization study for this phenomenon which is quite challenging to express. For the fieldwork, five buildings designed by Peter Zumthor were chosen. Zumthor stresses the importance of sensation, materiality and atmosphere in the architectural design process. Zumthor’s abstract design elements, their use in architectural space and the effect were determined using physical measurement. The findings were represented in “haptic mapping”. This visualization study consisted of a “haptic scatter chart”, “materiality- affect analysis” and “sensation analysis” and revealed that the phenomenon of touch and concepts identified it such as sensations, influence, materiality and mental associations are not abstract and inaccessible assumptions, but tools which can be included in the architectural design process.

  13. Affects and Affect Consciousness

    MONSEN, JON T.; EILERTSEN, DAG ERIK; MELGÅRD, TROND; ØDEGÅRD, PÅL

    1996-01-01

    Affect consciousness (AC) was operationalized as degrees of awareness, tolerance, nonverbal expression, and conceptual expression of nine specific affects. A semistructured interview (ACI) and separate scales were developed to assess these aspects of affect integration. Their psychometric properties were preliminarily explored by having 20 former psychiatric outpatients complete the interview. Concurrent validity was assessed by using DSM-III-R Axis I and II diagnoses, the Health-Sickness Rating Scale, SCL-90-R, and several indexes from the Minnesota Multiphasic Personality Inventory. Satisfactory interrater reliability and high levels of internal consistency supported the construct validity of the measure. Results suggest the most meaningful use of this instrument is in measuring specific affect and overall AC. Clinically, the ACI has provided highly specific and relevant qualitative data for use in planning psychotherapeutic interventions. PMID:22700292

    Proshyn Denys

    2015-12-01

    Full Text Available David Rapoport’s Wave theory of terrorism is one of the most oftencited theories in the literature on terrorist violence. Rapoport is praised for having provided researchers with a universal instrument which allows them to explain the origin and transformation of various historical types of terrorism by applying to them the concept of global waves of terrorist violence driven by universal political impulses. This article, testing the Wave theory against the recent phenomenon of homegrown jihadism in Europe, uncovers this theory’s fundamental weaknesses and questions its real academic and practical value.

  15. Global regulator SoxR is a negative regulator of efflux pump gene expression and affects antibiotic resistance and fitness in Acinetobacter baumannii.

    Li, Henan; Wang, Qi; Wang, Ruobing; Zhang, Yawei; Wang, Xiaojuan; Wang, Hui

    2017-06-01

    SoxR is a global regulator contributing to multidrug resistance in Enterobacteriaceae. However, the contribution of SoxR to antibiotic resistance and fitness in Acinetobacter baumannii has not yet been studied. Comparisons of molecular characteristics were performed between 32 multidrug-resistant A. baumannii isolates and 11 susceptible isolates. A soxR overexpression mutant was constructed, and its resistance phenotype was analyzed. The impact of SoxR on efflux pump gene expression was measured at the transcription level. The effect of SoxR on the growth and fitness of A. baumannii was analyzed using a growth rate assay and an in vitro competition assay. The frequency of the Gly39Ser mutation in soxR was higher in multidrug-resistant A. baumannii, whereas the soxS gene was absent in all strains analyzed. SoxR overexpression led to increased susceptibility to chloramphenicol (4-fold), tetracycline (2-fold), tigecycline (2-fold), ciprofloxacin (2-fold), amikacin (2-fold), and trimethoprim (2-fold), but it did not influence imipenem susceptibility. Decreased expression of abeS (3.8-fold), abeM (1.3-fold), adeJ (2.4-fold), and adeG (2.5-fold) were correlated with soxR overexpression (P baumannii.

  16. Net global warming potential and greenhouse gas intensity as affected by different water management strategies in Chinese double rice-cropping systems.

    Wu, Xiaohong; Wang, Wei; Xie, Xiaoli; Yin, Chunmei; Hou, Haijun; Yan, Wende; Wang, Guangjun

    2018-01-15

    This study provides a complete account of global warming potential (GWP) and greenhouse gas intensity (GHGI) in relation to a long-term water management experiment in Chinese double-rice cropping systems. The three strategies of water management comprised continuous (year-round) flooding (CF), flooding during the rice season but with drainage during the midseason and harvest time (F-D-F), and irrigation only for flooding during transplanting and the tillering stage (F-RF). The CH 4 and N 2 O fluxes were measured with the static chamber method. Soil organic carbon (SOC) sequestration rates were estimated based on the changes in the carbon stocks during 1998-2014. Longer periods of soil flooding led to increased CH 4 emissions, reduced N 2 O emissions, and enhanced SOC sequestration. The net GWPs were 22,497, 8,895, and 1,646 kg CO 2 -equivalent ha -1 yr -1 for the CF, F-D-F, and F-RF, respectively. The annual rice grain yields were comparable between the F-D-F and CF, but were reduced significantly (by 13%) in the F-RF. The GHGIs were 2.07, 0.87, and 0.18 kg CO 2 -equivalent kg -1 grain yr -1 for the CF, F-D-F, and F-RF, respectively. These results suggest that F-D-F could be used to maintain the grain yields and simultaneously mitigate the climatic impact of double rice-cropping systems.

  17. How Global is Global Civil Society?

    Neera Chandhoke

    2015-08-01

    Full Text Available In recent times the concept of global civil society has made its appearance on national and international intellectual, as well as political agendas, in a major way. It is of some interest that two other concepts, both of which call for transcendence of national boundaries in precisely the same way as global civil society does, have also made their appearance on the scene of intellectual debates at roughly the same time: the concept of cosmopolitanism and that of transnational justice. All three concepts have dramatically expanded the notion of commitment to one’s fellow beings beyond the nation state. And all three concepts have extended critiques of policies that violate the dignity of human beings from national governments to the practices of inter-national institutions such as the World Bank, the International Monetary Fund, and the World Trade Forum. In sum the inter-related concepts of global civil society, cosmopolitanism, and transnational justice have greatly enlarged the traditional domain of political theory. And yet for any political theorist who is acutely conscious of the phenomenon of power, these concepts are not unproblematic. For the practices of global civil society may just reinforce the intellectual and the moral power of the West over the postcolonial world. This is particularly true of say global human rights organizations. This paper will attempt to raise some questions of the concept and the practices of global civil society from the perspective of the countries of the South.

  19. Raynaud's phenomenon: peripheral catecholamine concentration and effect of sympathectomy.

    Nielsen, S L; Christensen, N J; Olsen, N; Lassen, N A

    1980-01-01

    The reaction to body and finger cooling was recorded in seven patients with relapse of primary Raynaud's phenomenon after sufficiently performed bilateral upper thoracic sympathectomy and for comparison in eight young women with primary Raynaud's phenomenon as well as in seven normal women. The forearm venous concentration of noradrenaline was lower and adrenaline concentration higher in the sympathectomized patients than in the other groups (p less than 0,05). Noradrenaline showed a significant increase during body cooling in normals and primary Raynaud's (p less than 0,05). There was no significant correlation between the vasoconstrictor response to cooling of a finger and the noradrenaline concentration probably due to the fact that skin vasoconstriction impeded release of noradrenaline from the skin. The relapse of Raynaud's phenomenon after surgically sufficient sympathectomy could not be treated by reserpine or alfa-adrenergic receptor blockers in two patients in whom this was tried.

  20. The role of ocean phenomenon in music compositions

    Liu, Chi-Min

    2016-04-01

    This is a preliminarily interdisciplinary study for exploring the elements of ocean phenomenon appearing in some compositions of classical music. The so-called ocean phenomenon contain wave conditions, climate change, coastal landform, and other natural events around or over the sea. In some music compositions, it is apparent that natural phenomenon over the sea influence the composers' moods and the music pieces they composed. In this poster, some music compositions in the 19th and the early 20th centuries will be introduced to demonstrate the relation between ocean and music works. These works include Meeresstille by Schubert, Étude Op.25 No.12 by Chopin, Fingal's Cave Overture by Mendelssohn, Der Fliegende Holländer by Wagner and La Mer by Debussy. In addition, present idea may give a novel way for music teachers to elucidate the knowledge of ocean science in classes.

    There are for and against arguments as regards the process of globalization. But what is globalization: a concept, a reality or a state as such? We can consider that globalization reflects the natural continuity of a process that appeared a long time ago and that has evolved ever since or a new phenomenon that was generated by the speed with which new technology and information flow. Milton Friedman, a fervent supporter of globalization, gives an answer to the question “what is globalization”...

    Full Text Available The Romanian language today faces a real offensive of the English language. There are fears that this intense process of influence endangers the identity of the Romanian language and its speakers’ linguistic consciousness. The complex influence exerted by English on Romanian is therefore seen as a threat. But English is the language of globalization, ICT, science and research, knowledge, international organizations and relations. The communication skills in English of the Romanian native speakers are a must in the Knowledge Society and the Age of Globalization. It is natural that English influence Romanian, through information and communication. The English language loans enrich Romanian and increase its capacity of covering the reality, continuously changing, its force to name and express aspects of the surrounding world. The contact with English, which places Romanian at the forefront of communication, by increasing its capacity to express a fast progressing civilization, also favours a process of acculturation, necessary in the world of the unity in diversity and of the New Humanism. "Anglicization" should not be seen in a negative sense, but as a positive phenomenon in the dialectic becoming of the language, a continuous process that ensures the adaptation, the actuality, the expressive force and vitality of Romanian

    2016-01-01

    To assess changes from 2007 to 2011 in the prevalence of tobacco use and tobacco-related indicators in Uganda by examining results from the Global Youth Tobacco Survey (GYTS). Both the 2007 (n=2,251) and 2011 (n=2,026) Uganda GYTS were conducted among students in primary seven, secondary one, two, and three. A two-stage cluster sample design was used to generate a representative sample of students for the surveys. Stata 12 software was used to provide weighted prevalence estimates and logistic regression models were developed to examine the relationship between factors that influence tobacco use and current tobacco use. The percentage of students who had ever smoked a cigarette, even just one or two puffs, declined from 15.6% in 2007 to 10.9% in 2011 (p=0.03). From 2007 to 2011, neither the percentage of current use of any tobacco (16.6% to 17.3%, p=0.75), nor the percentage of current (past 30 day) cigarette smoking (5.5% to 4.8%,p=0.59) changed significantly. Following adjustment, having parents [Adjusted Odds Ratio (AOR):1.9, 95% Confidence Interval (CI):1.3-2.8] and friends [AOR 2.5, 95% CI: 1.5-4.0)] who smoke, and having seen tobacco advertisements in print media [AOR 1.8(1.3-2.4)], were associated with greater odds of current tobacco use among students in 2007.Having parents who smoke [AOR;1.8, 95% CI: 1.1-3.0] was associated with greater odds of current tobacco use among students in 2011. From 2007 to 2011, no significant change occurred in the prevalence of current tobacco use or cigarette smoking among youth in Uganda. These findings underscore the importance of implementing effective population-level public health interventions, as outlined in the articles of the World Health Organization's Framework Convention on Tobacco Control, to prevent and reduce the use of tobacco among youth in Uganda.

    Full Text Available Multidisciplinary approaches involving daily phenomena are valuable teaching tools to stimulate reflections in order to comprehend that scientific knowledge is developed in a collective process, as well as to understand the importance that scientific research cannot be done in a unique area of knowledge for the full understanding of any phenomenon. We suggest the fluorescence phenomenon observation in some materials, objects and living organisms so that students realize the interaction between Physics, Chemistry and Biology, generally regarded as not correlated disciplines.

  5. The ferro-resonance, a phenomenon sometimes chaotic

    Grison, P; Kieny, J C; Riouai, M [Electricite de France (EDF), 92 - Clamart (France)

    1996-04-01

    The ferro-resonance is a resonance phenomenon involving the saturation of the magnetic core in transformers; in particular, it is generated by the energization of that equipment during a power system restoration. It exhibits classical periodic regimes, but also more complex ones, as harmonic, pseudo-periodic, even chaotic, which have been measured on site or during laboratory tests. The mathematical analysis of this phenomenon belongs to the theory of bifurcations; the use of a program solving non linear systems may lead to a better understanding of the observed overvoltages.

  6. What types of investors generate the two-phase phenomenon?

    Ryu, Doojin

    2013-12-01

    We examine the two-phase phenomenon described by Plerou, Gopikrishnan, and Stanley (2003) [1] in the KOSPI 200 options market, one of the most liquid options markets in the world. By analysing a unique intraday dataset that contains information about investor type for each trade and quote, we find that the two-phase phenomenon is generated primarily by domestic individual investors, who are generally considered to be uninformed and noisy traders. In contrast, our empirical results indicate that trades by foreign institutions, who are generally considered informed and sophisticated investors, do not exhibit two-phase behaviour.

    2009-01-01

    The Stokes phenomenon refers to the emergence of jump discontinuities in asymptotic expansions at specific rays in the complex plane. This book presents a radical theory for the phenomenon by introducing the concept of regularization. Two methods of regularization, Borel summation and Mellin-Barnes regularization, are used to derive general expressions for the regularized values of asymptotic expansions throughout the complex plane. Though different, both yield identical values, which, where possible, agree with the original functions. Consequently, asymptotics has been elevated to a true disc

  12. N2O emission from plant surfaces - light stimulated and a global phenomenon.

    Mikkelsen, Teis; Bruhn, Dan; Ambus, Per

    2017-04-01

    Nitrous oxide (N2O) is an important long-lived greenhouse gas and precursor of stratospheric ozone depleting mono-nitrogen oxides. The atmospheric concentration of N2O is persistently increasing; however, large uncertainties are associated with the distinct source strengths. Here we investigate for the first time N2O emission from terrestrial vegetation in response to natural solar ultra violet radiation. We conducted field site measurements to investigate N2O atmosphere exchange from grass vegetation exposed to solar irradiance with and without UV-screening. Further laboratory tests were conducted with a range of species to study the controls and possible loci of UV-induced N2O emission from plants. Plants released N2O in response to natural sunlight at rates of c. 20-50 nmol m-2 h-1, mostly due to the UV component. The emission rate is temperature dependent with a rather high activation energy indicative for an abiotic process. The prevailing zone for the N2O formation appears to be at the very surface of leaves. However, only c. 26% of the UV-induced N2O appears to originate from plant-N. Further, the process is dependent on atmospheric oxygen concentration. Our work demonstrates that ecosystem emission of the important greenhouse gas, N2O, may be up to c. 30% higher than hitherto assumed. Literature: Mikkelsen TN, Bruhn D & Ambus P. (2016).

    Highlights: • A low computational tool for heat transfer prediction on slug flows is presented. • The scooping phenomenon is modeled on a stationary approach. • The scooping phenomenon improved in 8% the heat transfer results. - Abstract: The heat transfer between the deep sea waters and the oil and gas mixtures flowing through production lines is a common situation in the petroleum industry. The optimum prediction of the liquid–gas flow parameters along those lines, when the intermittent flow pattern known as slug flow is dominant, has extreme importance in facilities' design. The mixture temperature drop caused by the colder sea waters, which can be regarded as an infinite medium with constant temperature, directly affects physical properties of the fluids such as the viscosity and specific mass. Gas expansion may also occur due to pressure and temperature gradients, thus changing the flow hydrodynamics. Finally, the temperature gradient affects the thermodynamic equilibrium between the phases, favoring wax deposition and thus increasing pressure drops or even blocking the production line. With those issues in mind, the present work proposes a stationary model to predict the mixture temperature distribution and the two-phase flow heat transfer coefficient based on the mass, momentum and energy conservation equations applied to different unit cell regions. The main contribution of the present work is the modeling of the thermal scooping phenomenon, i.e., the heat transfer between two adjacent unit cells due to the mass flux known as scooping. The model was implemented as a structured Fortran95 code with an upwind difference scheme. The results were compared to experimental data and presented good agreement. The analysis showed that the inclusion of the scooping phenomenon into the model resulted in an averaged 8% improvement in the temperature gradient calculation and heat transfer coefficient prediction for the flowing mixture.

    Thâmara Manoela Marinho Bezerra

    Full Text Available ABSTRACT INTRODUCTION: Mucoceles are common benign pseudocystic lesions of the oral cavity; their main etiological factors are trauma and ductal obstruction. Two histological patterns are found: mucus retention phenomenon (MRP and mucus extravasation phenomenon (MEP. Mucus extravasation phenomenon is the more common histological subtype and it mainly affects the lower lip. The knowledge of its main clinical features and management is important to assist health professionals in clinical practice. OBJECTIVE: This study aimed to determine the relative frequency and distribution of oral mucoceles in an oral pathology reference center. METHODS: Cross-sectional historical study that analyzed all cases pathologically diagnosed as mucus extravasation phenomenon by the department of anatomic pathology of an oral pathology referral center from June of 1970 to May of 2014, considering the clinical characteristics of the lesion and those relating to the patient. SPSS v. 20.0 software for Windows was used for descriptive analysis. RESULTS: During 43 years, 719 cases of mucus extravasation phenomenon (54.7% men and 45.3% women were registered, with the lower lip as the most commonly affected site (n = 484; 67.3%. The average age of patients was 20.8 years (SD ± 14.4 with a peak occurrence in the second decade of life. Most professionals had oral mucocele/ranula (n = 606; 84.3% as the initial clinical impression. CONCLUSION: Mucus extravasation phenomenon is a lesion that primarily affects young patients, affecting mainly the lower lip, and is commonly found in oral diagnostic services.

  16. The evolutionary approach to understand human low fertility phenomenon

    Cernak, Jozef

    2017-05-01

    Is it possible to reverse the low total fertility rate (TFR) in the developed world? Using a hypothetical model of population we have analysed the decline of the TFR which have took place in the background of ongoing global economic changes, and a liberalization process after the end of the Cold War. These phenomena have affected more that 110 millions of inhabitants of Central Europe and the Baltics and approximately 80 millions of inhabitants in Germany. The model has features of complex and evolving system of interacting individuals, and it enables to investigate a broad spectrum of input factors on individual decisions to limit the offspring. In the case of the TFR 2.1. The changes should stimulate more uniform spatial distribution of wealth, capital and usage. They will increase a number of self-sufficient and cooperative territories, to decrease the income inequality, to decrease labour and social mobilities. Societies should investigate the impacts of economic regulations and actions on the TFR trends in advance and take into account a biological nature of women more responsible.

  20. Presenteeism – (Not new phenomenon in the occupational environment

    Agata Wężyk

    2013-12-01

    Full Text Available Presenteeism, understood as being at work while ill, is not a new phenomenon. However, not long ago it has become an object of researchers' interest. Formerly, they focused mainly on absenteeism. In general, presenteesim is perceived as negative and very costly for employers. The majority of scientific studies refer to the problem of employees' productivity reduced due to their attending work despite being ill, but the knowledge about presenteeism's causes and effects (other than decreased productivity for both, the employee and the organisation, is still very limited. Especially in Poland there are very few scientific reports on this issue. However, the paper on presenteeism published recently (the 3/2013 issue of this Journal defined this phenomenon as a noneffective presence at work. The authors postulate to avoid pejorative connotation of this term by equating presenteeism with loss of productivity, and to separate this phenomenon from its possible negative and positive consequences. Thus, this paper aims at presenting current state of the art on this phenomenon, including such issues as definitional problems, measures and frequency of presenteeism, as well as its causes and consequences. In this paper presenteeism is presented in a wider perspective of its individual and contextual determinants. Med Pr 2013;64(6:847–861

  10. A Theoretical Model for the Prediction of Siphon Breaking Phenomenon

    Bae, Youngmin; Kim, Young-In; Seo, Jae-Kwang; Kim, Keung Koo; Yoon, Juhyeon

    2014-01-01

    A siphon phenomenon or siphoning often refers to the movement of liquid from a higher elevation to a lower one through a tube in an inverted U shape (whose top is typically located above the liquid surface) under the action of gravity, and has been used in a variety of reallife applications such as a toilet bowl and a Greedy cup. However, liquid drainage due to siphoning sometimes needs to be prevented. For example, a siphon breaker, which is designed to limit the siphon effect by allowing the gas entrainment into a siphon line, is installed in order to maintain the pool water level above the reactor core when a loss of coolant accident (LOCA) occurs in an open-pool type research reactor. In this paper, we develop a theoretical model to predict the siphon breaking phenomenon. In this paper, a theoretical model to predict the siphon breaking phenomenon is developed. It is shown that the present model predicts well the fundamental features of the siphon breaking phenomenon and undershooting height

  19. OLD AND NEW ECONOMIC GLOBALIZATION

    Elena MĂRGULESCU

    2015-07-01

    Full Text Available The retrospective of the theoretical approaches of the phenomenon of economic globalization in the last three decades emphasizes the movement of attention from the globalization of markets, from the'80s, to the globalization of production and services in the current decade. This trend is essentially the result of implementing new strategies by multinational and transnational companies. We try in this context to draw a line between the "globalization of markets" and the "globalization of production and services”. A feature of the globalization of production and services is the implementation of the arbitrage strategy in respect of one or more production factors. But the "globalization of production and services’ gains a new content due to the new possibilities offered by the “modularization” of production. Following, the arbitrage strategies began to address new factors, as for example the "functions" of production resulting from the restructuring of the product value chain.

  1. The Influence of Globalization on the Change and Convergence of Social Security Transfer: An Empirical Analysis for OECD Counties

    Jinyoung Hwang

    2007-12-01

    Full Text Available Using a cross-section of OECD countries, this paper examines the relationship between globalization and the change and convergence of social security transfer. Globalization has arguably had a profound impact on the use of social protection in states, since it is normally accompanied with increases in income inequality, polarization, and unemployment. In addition, globalization may lead to socio- economic policy harmonization across countries. The empirical results show that there exists a significant and positive relationship between social security transfer in GDP and the globalization index based on political, economic, and social integrations. Also, we found the convergence phenomenon of social security transfer in OECD countries, applying the traditional methodology of convergence and convergence. Therefore, there is evidence in OECD countries that globalization indirectly affects the convergence of social security transfer in addition to direct relation to social security transfer in GDP.

  2. Dip Phenomenon in High-Curved Turbulent Flows and Application of Entropy Theory

    Donatella Termini

    2018-03-01

    Full Text Available The estimation of velocity profile in turbulent open channels is a difficult task due to the significant effects of the secondary flow. The present paper investigates the mechanism of the velocity-dip phenomenon, whereby the location of the maximum velocity appears to be below the free surface. Previous studies conducted in straight channels relate the mechanism of the velocity-dip phenomenon to secondary flow induced by anisotropy of turbulence. This work focuses on high-curved channels where the secondary motion, which is also induced by the channel’s curvature, evolves along the bend. The width-to-depth ratio, B/h, is one of the most important parameters that are affecting the secondary motion entity. In particular, the present study aims to investigate the evolution of the velocity-dip along the bend for two values of the width-to-depth ratio and the applicability of the entropic model for the dip-phenomenon estimation. The results show that the velocity-dip is more accentuated for low values of the width-to-depth ratio, where the secondary motion plays a fundamental role in the distribution of the downstream flow velocity, although the velocity-dip is also present when the aspect ratio is higher than 10. Furthermore, the velocity profiles that were estimated by applying the entropic model are in good agreement with the measured ones, especially for B/h < 10.

  6. The novel phenomenon of noise-catalyzed chaos-order transitions

    Gassmann, F. [Paul Scherrer Inst. (PSI), Villigen (Switzerland)

    1997-06-01

    Numerical simulations of the Lorenzian water wheel have been used to investigate the influence of stochastic noise on the lifetime of chaotic transients. Whereas in one region of parameter space no noise dependency could be detected, a shortening of the lifetimes by more than four decades was found in another region. This large effect was produced by a significant modification of the attraction basin of a quasistable stationary state rather than by affecting the chaotic orbits before the chaos-order transition occurred. This novel phenomenon of noise-induced chaos-order transitions is not related to stochastic resonance or other noise-induced effects. (author) 2 figs., 5 refs.

So, the link between globalization and democracy, and its impact on the most important social and economic matters. We also surprise the impact of the internet revolution and its corolar e-commerce, and its consequences, sometimes unpredictible ones. Another annalysed problem is that of the governments trying, and sometimes succeeding to controll the money, products, peole and their ideas that freely move inside the national frontiers, thus going to slower or to stop the progress. Nevertheless, this global interraction between people also create phenomena of insecurity on different ways: terrorism, traffic of arms, drugs, economical aggresions causing the environment, and other inconvenient facts and situations.

  13. Study on Boiling Heat Transfer Phenomenon in Micro-channels

    Jeong, Namgyun [Inha Technical College, Incheon (Korea, Republic of)

    2017-09-15

    Recently, efficient heat dissipation has become necessary because of the miniaturization of devices, and research on boiling on micro-channels has attracted attention. However, in the case of micro-channels, the friction coefficient and heat transfer characteristics are different from those in macro-channels. This leads to large errors in the micro scale results, when compared to correlations derived from the macro scale. In addition, due to the complexity of the mechanism, the boiling phenomenon in micro-channels cannot be approached only by experimental and theoretical methods. Therefore, numerical methods should be utilized as well, to supplement these methods. However, most numerical studies have been conducted on macro-channels. In this study, we applied the lattice Boltzmann method, proposed as an alternative numerical tool to simulate the boiling phenomenon in the micro-channel, and predicted the bubble growth process in the channel.

    2015-01-01

    Cupping therapy is a traditional Chinese medicine used to heal psoriasis. The Koebner phenomenon is the occurrence of psoriatic lesions at the site of cutaneous injury. To describe the first case of biopsy-proven cupping-induced localized psoriasis, an example of the Koebner phenomenon. The histopathology of the lesions is described. A brief review of the literature regarding cupping therapy and its efficacy are discussed. A 45-year-old Asian male presented himself to the dermatology clinic for further treatment of his psoriasis. Four unusually circular plaques on the lower back were discovered. Pathologic diagnosis revealed an early lesion of psoriasis. on further inquiry, the patient admitted to undergoing a recent "cupping" procedure in an attempt to cure his condition. The efficacy of cupping therapy is controversial, and psoriatic patients may develop localized psoriasis through koebnerization as a result of cupping therapy rather than achieve desirable therapeutic benefits. © 2014 Canadian Dermatology Association.

  16. “Love” Phenomenon and Neurobiology of Love Relations

    Ali Evren Tufan

    2010-01-01

    Full Text Available The biology; especially the neurobiological features of the “love” phenomenon has recently started to attract attention. Love relations and attachment, which is closely related with them, are known to be important in health and disease. Love and love relations are found to be complex neurobiological phenomena based on activation of the limbic system of the brain. Those processes involve oxytocin, vasopressin, dopamine and serotonergic functions. Additionally, endorphine and endogenous opiate systems as well as nitrous oxide play role in those processes. The stages of love and love relations may demonstrate different neurochemical and neurophysiological features and may partially overlap with m aternal, romantic and sexual love and attachments. The aim of this article is to evaluate the common neurobiological pathways underlying the “love” phenomenon as well as their importance in medicine and health.

  17. Study on the Temperature Separation Phenomenon in a Vortex Chamber

    Ye, A Ran; Guang, Zhang; Kim, Heuy Dong [Andong National University, Andong (Korea, Republic of)

    2014-09-15

    A vortex chamber is a simple device that separates compressed gas into a high-temperature stream and a low-temperature stream. It is increasing in popularity as a next-generation heat exchanger, but the flow physics associated with it is not yet well understood. In the present study, both experimental and numerical analyses were performed to investigate the temperature separation phenomenon inside the vortex chamber. Static pressures and temperatures were measured using high-sensitivity pressure transducers and thermocouples, respectively. Computational fluid dynamics was applied to simulate 3D unsteady compressible flows. The simulation results showed that the temperature separation is strongly dependent on the diameter of the vortex chamber and the supply pressure at the inlet ports, where the latter is closely related to the viscous work. The previous concept of a pressure gradient wave may not be a reasoning for temperature separation phenomenon inside the vortex chamber.

    Peripheral vascular abnormalities caused by a dysregulation between peripheral vasoconstriction and vasodilatation, clinically appearing with Raynaud's phenomenon, have been described in anorexia nervosa but specific characteristics of microcirculation in anorexic patients have not yet been studied. We performed nailfold videocapillaroscopy to assess microcirculatory alteration in anorexic patients and found three different patterns: normal, aspecific and early scleroderma pattern. We also evaluated several laboratory and clinical parameters to better assess our capillaroscopic findings. None of the clinical parameters examined correlated with specific capillaroscopic findings. An increased risk of autoimmune diseases in eating disorder patients has been described. Our results evidenced an association between early scleroderma capillaroscopic pattern and Raynaud's phenomenon that occurs in anorexia nervosa patients, whereas no significant association was found between all three capillaroscopic patterns and the presence of autoantibodies, as well as ESR and CRP values. Our study reveals that patients with AN suffering from RP exhibit NVC findings typical of connective tissue diseases.

  19. A system view of the No Fault Found (NFF) phenomenon

    Soederholm, Peter

    2007-01-01

    When a unit is tested outside a technical system, it has normally been removed due to a fault. However, in some cases the external test may not discover any fault and a No Fault Found (NFF) event may occur. The NFF phenomenon is a major problem when dealing with complex technical systems, and its consequences may be manifested in decreased safety and dependability and increased life cycle costs. There are multiple interacting causes of NFF, demanding tough requirements for successful solutions. The purpose of this paper is to describe the phenomenon of NFF and to highlight possible improvements for the prevention of causes of NFF and the reduction of its consequences. The study was performed as an explorative literature study, and the analysis was based on a holistic system view. The identified causes and solutions are related to life cycle stages, availability performance factors, and system stakeholders

  7. Perspectives for research of the procrastination phenomenon in professional work

    Valentina V. Barabanshchikova

    2015-12-01

    Full Text Available The paper describes the current state of the procrastination phenomenon in professional work, reviews the basic unexplored aspects in this area, and highlights the promising areas of scientific analysis. The survey of the existing literature periodization shows that the quantity of researches devoted to procrastination is growing exponentially every year. In spite of a pronounced research interest in this construct, in native and foreign psychological science procrastination phenomenon in the professional work is represented insufficiently. Firstly, there is no common and generally accepted definition of procrastination (Corkin, Yu, Lindt, 2011; Steel, 2010; Krause, Freund, 2014, that suggests that there is a deep terminological crisis in this area. Secondly, the characteristic of delaying the implementation of the elements of workload is represented only by the example of a fairly narrow range of professional activities, which makes it relevant to study the specificity of the differentiated functioning of the phenomenon on the material of a wide range of professions. Thirdly, in psychology there are no information about the peculiarities of the so-called “active” procrastination manifestations in professional activity, which is the tendency of conscious assignments delaying to achieve the optimum final result (Chu, Choi, 2005; Choi, Moran, 2009. Fourthly, there is an acute shortage of standardized psychodiagnostic tools to evaluate this phenomenon in work (most of the existing methods have been tested on samples of students and are aimed at identifying academic procrastination. In the fifth place, there are no science-based allocation of methods of coping with destructive manifestations of the psychological strategy of the job functions postponement in a professional work.

    1993-01-01

    The use of unlabeled samples in improving the performance of classifiers is studied. When the number of training samples is fixed and small, additional feature measurements may reduce the performance of a statistical classifier. It is shown that by using unlabeled samples, estimates of the parameters can be improved and therefore this phenomenon may be mitigated. Various methods for using unlabeled samples are reviewed and experimental results are provided.

  9. ACTIVITY-BASED ANOREXIA AS A THERMOREGULATION PHENOMENON

    Carlos Javier Flores Aguirre

    2012-12-01

    Full Text Available Activity Based Anorexia (ABA is a phenomenon that results from exposing rats to a feeding program of about 1 to 1.5 h per day, giving them free access to an activity wheel the rest of the time. The reported effects are high levels of activity without a visible compensation in food intake, and in consequence a low body weight. There is a variety of interpretations about the causes of this phenomenon. However, there are two main theories: one of them says that ABA is a product of adaptive failure to the new feeding regime and that the activity in the wheel interferes with such adaptation. The second theoretical position says that the activity acquires reinforcing properties due to feeding restrictions which causes body weight loss and, in turn, more activity. At present, both theories have been interpreted as contradictory. Nevertheless, a series of studies have revealed that the temperature of the environment and in consequence the subjects’ body tem-perature play an essential role in the findings of the field, giving sense to both theories and evidencing their complementariness. The aim of this paper is to re-view the empirical evidence that supports the hypothesis of ABA as a thermoregu-lation phenomenon.

  10. The emerging magnetic flux and the elementary eruptive phenomenon

    Mouradian, Z.; Martres, M.J.; Soru-Escaut, I.

    1983-01-01

    Observational studies before and during the flare start were made in Hα(3-lambda heliograph at Meudon Observatory) on a large sample of ''elementary'' flares, both on the disk and along the limb of the Sun. The concept of elementary eruptive phenomenon (EEP) is proposed to describe these observational data. The EEP may be considered as the basic element of complex flares which, then, are built up by the juxtaposition of several EEP. In the inferred scenario, the chromospheric eruptive phenomenon consists of two systems of loops: one cold - the surging arch - Tapprox.=10 4 K, the other hot - the flaring arch -, covering a temperature range up to 10 7 K. The footpoints of the two systems remain differentiated until extinction of the phenomenon; their behaviour over time differs also. The surging arch (the magnetic flux emergence) rises first progressively in the solar atmosphere and the upper part of the loop is heated to coronal temperatures. The classical surge which is observed in the center of the Hα line, after the flash phase of the flare, is only the late development of the surging arch. The flaring arch originates from a pre-existing low loop, which is also to rise in the solar atmosphere. These two systems coexist and may combine to form such physical characteristics as mass motion, expansion and post-flash phase. (orig.)

    Development of the phenomenon of cavitation in cavitation behavior requires knowledge of both plant and equipment working in the facility. This paper presents a diagram of cavitational behavior for a butterfly valve with a diameter of 100 mm at various openings, which was experimentally built. We proposed seven stages of evolution of the phenomenon of cavitation in the case of a butterfly valve. All these phases are characterized by pressure drop, noise and vibration at various flow rates and flow sections through the valve. The level of noise and vibration for the seven stages of development of the phenomenon of cavitation were measured simultaneously. The experimental measurements were comprised in a knowledge database used in training of a neural network of a neural flow controller that maintains flow rate constantly in the facility by changing the opening butterfly valve. A fuzzy position controller is used to access the valve open. This is the method proposed to provide operational supervision outside the cavitation for a butterfly valve.

  14. ABOUT POTENTIALLY ACCEPTABLE TRACTION OF THE UNEXPECTED PHENOMENON

    BOL’SHAKOV V. I.

    2017-05-01

    Full Text Available Summary. Raising of problem. The article notes that constructive denial of traditional beliefs is often a powerful source of scientific discoveries. However, the absence of a constructive negation of the diva phenomenon can not be perceived as a lack of an adequate interpretation of it. It is assumed that the interpretation of Diva phenomena can be based on the definition of the area of their existence, which is computationally irreducible within the boundaries of existing methods of identification. The definition of such an area initiates. The formation of hypotheses that interpret the assumptions about its existence. An example of the origin of one of the hypotheses is considered in this essay. Drawing on relativistic physics and cosmology, the authors put forward a hypothesis about the possibility of the existence of a parallel space-time continuum to the existing one. This allows us to assume the existence of fragments of diva-type phenomena shifted in time to the main such continuum. The presence of such a phenomenon allows one to assume a mental connection of the percipient to a parallel space-time continuum and to implement time-shifted predictions. As an example, the existence of a computationally irreducible region of a concrete psychophysical phenomenon (sculptural portraying is given.

  16. Life as a planetary phenomenon: the colonization of Mars

    Margulis, L.; Guerrero, R.

    1995-01-01

    Life is a planet-wide phenomenon in which its components incessantly move and interact. Life imperatively recycles its parts at the surface of the Earth in a chemical transformation and physical transport that depends utterly on the energy from a recent star, the Sun. Humanity, entirely dependent on other beings, plays a recent and relatively small part in the great phenomenon of life that transports and transforms the surface of the Earth. Our species accelerates but does not dominate the metabolism of the Earth system. Ironically, during the Apollo days of the sixties, fears were rampant that Martian or other extraterrestrial "germs" might "contaminate" our planet. After Viking, such fears are seen as the manifestation of cultural paranoia. The Viking missions complemented ground-based astronomical observation and yielded definitive evidence for the lack of life on the red planet. The Gaia hypothesis states that the surface temperature, composition of the reactive gases, oxidation state, alkalinity-acidity on today's Earth are kept homeorrhetically at values set by the sum of the activities of the current biota. Life, in other words, not only produces and maintains its immediate environment, but appears on Earth only as a planetary phenomenon. Since the natural tendency of all life is to grow exponentially to fill proximal volume, the question now "can life ecopoietically expand to Mars?" is entirely equivalent to the query of "can Gaia reproduce?".

  17. Simulation of the AC corona phenomenon with experimental validation

    Villa, Andrea; Barbieri, Luca; Marco, Gondola; Malgesini, Roberto; Leon-Garzon, Andres R

    2017-01-01

    The corona effect, and in particular the Trichel phenomenon, is an important aspect of plasma physics with many technical applications, such as pollution reduction, surface and medical treatments. This phenomenon is also associated with components used in the power industry where it is, in many cases, the source of electro-magnetic disturbance, noise and production of undesired chemically active species. Despite the power industry to date using mainly alternating current (AC) transmission, most of the studies related to the corona effect have been carried out with direct current (DC) sources. Therefore, there is technical interest in validating numerical codes capable of simulating the AC phenomenon. In this work we describe a set of partial differential equations that are comprehensive enough to reproduce the distinctive features of the corona in an AC regime. The model embeds some selectable chemical databases, comprising tens of chemical species and hundreds of reactions, the thermal dynamics of neutral species and photoionization. A large set of parameters—deduced from experiments and numerical estimations—are compared, to assess the effectiveness of the proposed approach. (paper)

  18. Loss and damage affecting the public health sector and society resulting from flooding and flash floods in Brazil between 2010 and 2014 - based on data from national and global information systems.

    Minervino, Aline Costa; Duarte, Elisabeth Carmen

    2016-03-01

    This article outlines the results of a descriptive study that analyses loss and damage caused by hydrometeorological disasters in Brazil between 2010 and 2014 using the EM DAT (global) and S2iD (national) databases. The analysis shows major differences in the total number of disaster events included in the databases (EM-DAT = 36; S2iD = 4,070) and estimated costs of loss and damage (EM-DAT - R$ 9.2 billion; S2iD - R$331.4 billion). The analysis also shows that the five states most affected by these events are Santa Catarina, Rio Grande do Sul, Minas Gerais, São Paulo and Paraná in Brazil's South and Southeast regions and that these results are consistent with the findings of other studies. The costs of disasters were highest for housing, public infrastructure works, collectively used public facilities, other public service facilities, and state health and education facilities. The costs associated with public health facilities were also high. Despite their limitations, both databases demonstrated their usefulness for determining seasonal and long-term trends and patterns, and risk areas, and thus assist decision makers in identifying areas that are most affected by and vulnerable to natural disasters.

  3. Phenomenon of primary and secondary extinction in textured material

    Kryshtab, T.G.; Palacios G, J.; Mazin, M.O.

    2002-01-01

    A new X-ray diffraction method is proposed for a more exact calculation of pole figures to determine the crystallite orientation distribution function (CODF) in textured materials, by the introduction of a correction of the integrated intensity of the diffracted beam due to the phenomenon of extinction. Besides, for the case of a symmetrical Bragg reflection from an ''infinitely thick'' flat parallel plate textured sample a simple solution is developed for the problem of separation and determination of primary and secondary extinction parameters, which can be present simultaneously. The determination of these parameters gives additional information about crystallite structure and allows us to evaluate the average subgrains size and their disorientation, respectively. In this work according to the dynamic diffraction theory, it is shown that the extinction length, which is directly connected with the phenomenon of primary extinction, in the Bragg geometry for σ polarization (perpendicular) is independent on the wavelength used for a given reflection. On the other hand, the additional contribution from secondary extinction depends on X-ray wavelength due to the change of effective absorption coefficient. Considering this fact, the calculations of pole density and the parameters of primary and secondary extinction are performed using the same strong reflection for two different wavelengths and, for one of these wavelengths, a second order of reflection. For confirmation of the proposed method a partially cold rolled aluminium sample and an aluminium powder standard sample were measured. The corrected pole densities, the values of primary and secondary extinction and the average sizes of perfect coherent areas and average angle of disorientation of subgrains in the selected directions were obtained. The obtained results show that the precise X-ray diffraction characterization of textured materials requires the consideration, in general, of primary as well as secondary

  4. The Hurst Phenomenon in Error Estimates Related to Atmospheric Turbulence

    Dias, Nelson Luís; Crivellaro, Bianca Luhm; Chamecki, Marcelo

    2018-05-01

    The Hurst phenomenon is a well-known feature of long-range persistence first observed in hydrological and geophysical time series by E. Hurst in the 1950s. It has also been found in several cases in turbulence time series measured in the wind tunnel, the atmosphere, and in rivers. Here, we conduct a systematic investigation of the value of the Hurst coefficient H in atmospheric surface-layer data, and its impact on the estimation of random errors. We show that usually H > 0.5 , which implies the non-existence (in the statistical sense) of the integral time scale. Since the integral time scale is present in the Lumley-Panofsky equation for the estimation of random errors, this has important practical consequences. We estimated H in two principal ways: (1) with an extension of the recently proposed filtering method to estimate the random error (H_p ), and (2) with the classical rescaled range introduced by Hurst (H_R ). Other estimators were tried but were found less able to capture the statistical behaviour of the large scales of turbulence. Using data from three micrometeorological campaigns we found that both first- and second-order turbulence statistics display the Hurst phenomenon. Usually, H_R is larger than H_p for the same dataset, raising the question that one, or even both, of these estimators, may be biased. For the relative error, we found that the errors estimated with the approach adopted by us, that we call the relaxed filtering method, and that takes into account the occurrence of the Hurst phenomenon, are larger than both the filtering method and the classical Lumley-Panofsky estimates. Finally, we found that there is no apparent relationship between H and the Obukhov stability parameter. The relative errors, however, do show stability dependence, particularly in the case of the error of the kinematic momentum flux in unstable conditions, and that of the kinematic sensible heat flux in stable conditions.

  5. Modeling the Pineapple Express phenomenon via Multivariate Extreme Value Theory

    Weller, G.; Cooley, D. S.

    2011-12-01

    The pineapple express (PE) phenomenon is responsible for producing extreme winter precipitation events in the coastal and mountainous regions of the western United States. Because the PE phenomenon is also associated with warm temperatures, the heavy precipitation and associated snowmelt can cause destructive flooding. In order to study impacts, it is important that regional climate models from NARCCAP are able to reproduce extreme precipitation events produced by PE. We define a daily precipitation quantity which captures the spatial extent and intensity of precipitation events produced by the PE phenomenon. We then use statistical extreme value theory to model the tail dependence of this quantity as seen in an observational data set and each of the six NARCCAP regional models driven by NCEP reanalysis. We find that most NCEP-driven NARCCAP models do exhibit tail dependence between daily model output and observations. Furthermore, we find that not all extreme precipitation events are pineapple express events, as identified by Dettinger et al. (2011). The synoptic-scale atmospheric processes that drive extreme precipitation events produced by PE have only recently begun to be examined. Much of the current work has focused on pattern recognition, rather than quantitative analysis. We use daily mean sea-level pressure (MSLP) fields from NCEP to develop a "pineapple express index" for extreme precipitation, which exhibits tail dependence with our observed precipitation quantity for pineapple express events. We build a statistical model that connects daily precipitation output from the WRFG model, daily MSLP fields from NCEP, and daily observed precipitation in the western US. Finally, we use this model to simulate future observed precipitation based on WRFG output driven by the CCSM model, and our pineapple express index derived from future CCSM output. Our aim is to use this model to develop a better understanding of the frequency and intensity of extreme

    Zhang, Runfa; Bilige, Sudao; Bai, Yuexing; Lü, Jianqing; Gao, Xiaoqing

    2018-02-01

    Based on searching the combining of quadratic function and exponential (or hyperbolic cosine) function from the Hirota bilinear form of the dimensionally reduced p-gBKP equation, eight class of interaction solutions are derived via symbolic computation with Mathematica. The submergence phenomenon, presented to illustrate the dynamical features concerning these obtained solutions, is observed by three-dimensional plots and density plots with particular choices of the involved parameters between the exponential (or hyperbolic cosine) function and the quadratic function. It is proved that the interference between the two solitary waves is inelastic.

  12. On the phenomenon of mixed dynamics in Pikovsky-Topaj system of coupled rotators

    Gonchenko, A. S.; Gonchenko, S. V.; Kazakov, A. O.; Turaev, D. V.

    2017-07-01

    A one-parameter family of time-reversible systems on three-dimensional torus is considered. It is shown that the dynamics is not conservative, namely the attractor and repeller intersect but not coincide. We explain this as the manifestation of the so-called mixed dynamics phenomenon which corresponds to a persistent intersection of the closure of the stable periodic orbits and the closure of the completely unstable periodic orbits. We search for the stable and unstable periodic orbits indirectly, by finding non-conservative saddle periodic orbits and heteroclinic connections between them. In this way, we are able to claim the existence of mixed dynamics for a large range of parameter values. We investigate local and global bifurcations that can be used for the detection of mixed dynamics.

  15. Preventing Instability Phenomenon in Gas-lift Optimization

    Mohammad Reza Mahdiani

    2015-01-01

    Full Text Available One of the problems that sometimes occur in gas allocation optimization is instability phenomenon. This phenomenon reduces the oil production and damages downhole and surface facilities. Different works have studied the stability and suggested some solutions to override it, but most of them (such as making the well intelligent are very expensive and thus they are not applicable to many cases. In this paper, as a new approach, the stability has been studied in gas allocation optimization problems. To prevent the instability, instability has been assumed as a constraint for the optimizer and then the optimizer has been run. For the optimization, first a genetic algorithm and then a hybrid of genetic algorithm and Newton-Quasi have been used, and their results are compared to ensure the good performance of the optimizer; afterwards, the effect of adding the instability constraint to the problem on production reduction have been discussed. The results show that the production loss with adding this constraint to the system is very small and this method does not need any additional and expensive facilities for preventing the instability. Therefore, the new method is applicable to different problems.

  16. Raynaud’s phenomenon in the rheumatologist’s practice

    R.T. Alekperov

    2014-05-01

    Full Text Available Raynaud’s phenomenon (RP is a common condition that predominantly occurs among women. The onset age in most cases is under 30 years. The phenomenon was first described by M. Raynaud over 150 years ago. Primary (Raynaud’s disease and secondary RP were subsequently distinguished. Pathophysiology of RP has not been fully elucidated yet; RP seems to be a multifactor disease. A pronounced vasospasm in response to stimuli is believed to be caused by disruption in the central and local mechanisms of regulation of vascular tonus. Vascular endothe- lial, intravascular, and neuronal disorders are the key ones among these factors. Structural changes in vessels that can be observed by nailfold capillaroscopy play a significant role in pathophysiology of secondary RP. The key step in the diagnosis of RP is identifying its clinical variant, since secondary RP may be a sign or a premonitory symptom of certain autoimmune, hematologic, endocrine, neoplastic, and other disorders. Secondary RP is most frequently observed in patients with systemic rheumatoid diseases. Therapy of secondary RP provides no satisfactory out- comes, since there is no complete conception about the pathophysiological mechanisms of its development. Different groups of drugs are cur- rently used to treat RP, including calcium channels blockers, phosphodiesterase type 5 inhibitors, endothelin receptor antagonists, etc. This review focuses on pathogenesis, the algorithm of early and differential diagnosis of RP, and current approaches to therapy based on the analysis of the published and our own data.

  18. The phenomenon of mobbing in Serbia and Europe

    Trišić Marko

    2017-01-01

    Full Text Available As the phenomenon of abuse in the workplace came to a closer public eye of a broader audience through media coverage, there is not a more fertile ground for a fully detailed problem explanation and search for its short or long-term solution. The dose of seriousness concerning the issue of mobbing isn’t only given for its negative effect on a business organization, but also for the mutation of a society’s culture, as well. The research paper outlines the mobbing phenomenon by presenting the theoretical and practical (statistical diagnosis through which, for a better understanding of the situation, there are added testimonies of mobbing victims, as well as legal and extra-judicial solutions for the issue. The observation of the phenomena is focused on the research and data presentation, using examples from Serbia and Europe. Putting aside the obvious differences in approach, a great space for implementation of European developed countries’ principles can be seen. The same principles could be introduced on the domestic scene, with the introduction of mandatory work conditions that are considered decent.

  19. Elephant's foot phenomenon in liquid storage tanks

    Chen, C.Q.

    1983-01-01

    This paper presents a method for analyzing the seismic response of a flat bottomed cylindrical liquid storage tank to vertical earthquake excitation. Here, vertical earthquake acceleration is considered to correspond to an increase in the density of a stored liquid. Taking into account the vertical and horizontal earthquake loads, hydrostatic pressure, and considering restrictive moment and shear forces at shell-bottom welded joint, the author has calculated circumferential and longitudinal stresses. These are combined to more accurately approximate the stresses at the base shell course. The calculated result closely conforms to the actual damage, termed ''elephant's foot,'' observed in the fuel storage tanks damaged in the Tangshan earthquake. This result shows that the ''elephant's foot'' phenomenon is not caused by buckling of the tank shell due to longitudinal compressive stresses resulting from horizontal earthquake acceleration, but rather by the combined stresses in the base shell course of the storage tank exceeding the yield strength of the shell course material. The effect due to vertical earthquake load is more than the effect from the horizontal load. Finally, some earthquake resistant methods to prevent the ''elephant's foot'' phenomenon are suggested by the author.

  20. All Impostors Aren't Alike - Differentiating the Impostor Phenomenon.

    Leonhardt, Mona; Bechtoldt, Myriam N; Rohrmann, Sonja

    2017-01-01

    Following up on earlier investigations, the present paper analyzes construct validity of the impostor phenomenon. It examines the question whether the impostor phenomenon is a homogeneous construct or whether different types of persons with impostor self-concept can be distinguished on the basis of related characteristics. The study was conducted with professionals in leadership positions exhibiting a pronounced impostor self-concept ( n = 183). Cluster-analytic procedures indicated the existence of two different types: one group which, in line with the literature (e.g., Clance, 1985), possessed traits classified as fairly unfavorable ("true impostors") and another group which can be described as largely unencumbered ("strategic impostors"). The present study suggests two types of impostorism: "True" impostors characterized by the negative self-views associated with the construct definition, and more "strategic" impostors who seem to be less encumbered by self-doubt. It is assumed that "strategic impostors" are characterized by a form of deliberate self-presentation. Therefore, the impostor self-concept cannot principally be viewed as a dysfunctional personality style. This distinction should be more carefully considered in further research and in therapeutic interventions.

  1. Tyrosine isomers mediate the classical phenomenon of concomitant tumor resistance.

    Ruggiero, Raúl A; Bruzzo, Juan; Chiarella, Paula; di Gianni, Pedro; Isturiz, Martín A; Linskens, Susana; Speziale, Norma; Meiss, Roberto P; Bustuoabad, Oscar D; Pasqualini, Christiane D

    Concomitant tumor resistance (CR) is a phenomenon originally described in 1906 in which a tumor-bearing host is resistant to the growth of secondary tumor implants and metastasis. Although recent studies have indicated that T-cell-dependent processes mediate CR in hosts bearing immunogenic small tumors, manifestations of CR induced by immunogenic and nonimmunogenic large tumors have been associated with an elusive serum factor. In this study, we identify this serum factor as tyrosine in its meta and ortho isoforms. In three different murine models of cancer that generate CR, both meta-tyrosine and ortho-tyrosine inhibited tumor growth. In addition, we showed that both isoforms of tyrosine blocked metastasis in a fourth model that does not generate CR but is sensitive to CR induced by other tumors. Mechanistic studies showed that the antitumor effects of the tyrosine isoforms were mediated, in part, by early inhibition of mitogen-activated protein/extracellular signal-regulated kinase pathway and inactivation of STAT3, potentially driving tumor cells into a state of dormancy. By revealing a molecular basis for the classical phenomenon of CR, our findings may stimulate new generalized approaches to limit the development of metastases that arise after resection of primary tumors, an issue of pivotal importance to oncologists and their patients. ©2011 AACR

  2. [The knowledge of animal respiration as a combustion phenomenon].

    de Micheli, Alfredo

    2014-01-01

    The different stages leading to knowledge of the phenomenon of animal breathing are going from some writings in Corpus Hippocraticum to Aristoteles' and Galen's works, who considered the heart as the source of the animal heat. Later, Miguel Servet suggested that the inspired air can achieve other functions besides cooling the blood. After that, different explications of the animal heat were raised. About 1770, due to progress of knowledge in the chemistry field, first Mayow and later Black began to consider the animal respiration as a combustion. The important treatise Méthode de nomenclature chimique, published by Guyton de Morveau et al. in 1787 and soon after the Traité élémentaire de chimie de Lavoisier (1789) provided a solid support to Lavoisier's thought. This way on arrived to consider analogous the respiration and combustion phenomena. Studies on the animal respiration phenomenon continued in xix century and in the following century it was possible to apply thermodynamic principles to biology: "generalized thermodynamics".

  3. Effects of Forgetting Phenomenon on Surveillance Test Interval

    Lee, Ho-Joong; Jang, Seung-Cheol

    2007-01-01

    Technical Specifications (TS) requirements for nuclear power plants (NPPs) define Surveillance Requirements (SRs) to assure safety during operation. SRs include surveillance test intervals (STIs) and the optimization of the STIs is one of the main issues in risk-informed applications. Surveillance tests are required in NPPs to detect failures in standby equipment to assure their availability in an accident. However, operating experience of the plants suggests that, in addition to the beneficial effects of detecting latent faults, the tests also may have adverse effects on plant operation or equipment; e.g., plant transient caused by the test and wear-out of safety system equipment due to repeated testing. Recent studies have quantitatively evaluated both the beneficial and adverse effects of testing to decide on an acceptable test interval. The purpose of this research is to investigate the effects of forgetting phenomenon on STI. It is a fundamental human characteristic that a person engaged in a repetitive task will improve his performance over time. The learning phenomenon is observed by the decrease in operation time per unit as operators gain experience by performing additional tasks. However, once there is a break of sufficient length, forgetting starts to take place. In surveillance tests, the most common factor to determine the amount of forgetting is the length of STI, where the longer the STI, the greater the amount of forgetting

    Surface Plasmon Resonance (SPR) phenomenon of the insulating polyaniline (PANI) is has been observed. Surface Plasmon (SP) is the traveled electromagnetic wave that passes through the interface of dielectric metal and excited by attenuated total reflection (ATR) method in Kretschmannn configuration (Au-PANI prism). The resonance condition is observed through the angle of SPR in such condition that SP wave is coupled by the evanescent constant of laser beam. In this research, the laser beam was generated by He–Ne and its wavelength (λ) was 632,8 nm. SPR curve is obtained through observation of incidence angles of the laser beam in prism. SPR phenomenon at the boundary between Au – PANI layer has showed by reflection dip when the laser beam passes through the prism. In this early study, the observation was carried out through simulation Winspall 3.02 software and preliminary compared with some experimental data reported in other referred literatures. The results shows that the optimum layer of Au and polyaniline are 50 and 1,5 nm thick respectively. Our own near future experimental work would be further performed and reported elsewhere.

  5. The God effect quantum entanglement, science’s strangest phenomenon

    Clegg, Brian

    2006-01-01

    The phenomenon that Einstein thought too spooky and strange to be true What is entanglement? It's a connection between quantum particles, the building blocks of the universe. Once two particles are entangled, a change to one of them is reflected---instantly---in the other, be they in the same lab or light-years apart. So counterintuitive is this phenomenon and its implications that Einstein himself called it "spooky" and thought that it would lead to the downfall of quantum theory. Yet scientists have since discovered that quantum entanglement, the "God Effect," was one of Einstein's few---and perhaps one of his greatest---mistakes. What does it mean? The possibilities offered by a fuller understanding of the nature of entanglement read like something out of science fiction: communications devices that could span the stars, codes that cannot be broken, computers that dwarf today's machines in speed and power, teleportation, and more. In The God Effect, veteran science writer Brian Clegg has written an ex...

  6. THE GENERATING AND COMPLEMENTARY EFFECTS OF THE UNDERGROUND ECONOMY PHENOMENON

    Corneliu Sorin BAICU

    2016-12-01

    Full Text Available For a comprehensive understanding of the informal sector, an analysis addressing the relationships and links between the morphology and etiology of the underground economy, on the one hand, and its effects on the economic, social or legal, on the other hand is required. The double identity, that of cause phenomenon and effect phenomenon, that the underground economy has, gives it a special status in explaining certain phenomena which vitiates the economic and social life. The generating and complementary effects of the underground area covered in this study are analyzed in terms of the following vectors of analysis: tax evasion, illegal work and money laundering. Tax evasion represents the central core of the underground economy and faithfully expresses the fiscal monetary policies ,the fiscal mortality and the degree of compliance of the taxpayer. Undeclared work is an indicator of the labor market in the informal economy and is a good barometer for analyzing the demand and supply of labor in the visible economy. Money laundering defines the level of economic and financial crime and reflects the level of illegal use of capital on the black market. Tax evasion, money laundering and illegal work can only develop on a framework provided by illicit markets for goods, services and labor. Beyond the, unidirectional or bidirectional relationships between phenomena, the paper consists in a plea for an interdependent, multi-causal analysis of the phenomena and operating mechanisms of the relationships within and outside the underground economy.

  7. The clinicide phenomenon: an exploration of medical murder.

    Kaplan, Robert

    2007-08-01

    The aim of this paper is to explore the phenomenon of clinicide. The study of medical killers is barely in its infancy. Clinicide is the unnatural death of multiple patients in the course of treatment by a doctor. Serial medical killing is a relatively new phenomenon. The role model is Dr Marcel Petiot, the worst serial killer in French history. More recently, Dr Harold Shipman was Britain's worst serial killer and in the United States and Zimbabwe, Dr Michael Swango killed 60 patients. A number of doctors have such high patient death rates that it cannot be ignored. At some level, these doctors have an awareness of what they are doing, countered by an overweening refusal to acknowledge the implications or desist from further treatment. Treatment killer offences usually occur on the basis of serial mental illness, but may include the contentious area of euthanasia killing. Doctors have frequently been accomplices in state repression, brutality and genocide in direct contravention to their sanctioned role to relieve suffering and save life. They have become mass murderers on an exponential scale, making any comparison with a doctor killing his own patients almost risible. Many clinicidal doctors have extreme narcissistic personalities, a grandiose view of their own capability and inability to accept that they could be criticized or need assistance from other doctors. Such doctors develop a God-complex, getting a vicarious thrill out of ending suffering and by determining when a person dies.

  12. Globalization and Technology

    Traian-Alexandru Miu

    2016-01-01

    Full Text Available Globalization, very complex phenomenon, involves overcoming the barriers between different states, which allowed the rapid transfer of capital, technology, information, and the "toxins" from one country to another. First, the technology formed the basis of rapid expansion of great ideas promoted by globalization. Undeniable progress in the field of technology and science, has conferred to the man extraordinary powers that have been used most often to the detriment of his spiritual progress. We must not deny that science and technology have brought many benefits to human, and he could expand the knowledge horizon upon the world in which he lives, exploiting information acquired and share them with others. Science and technology must become for postmodern man ways of talk and communion between human and divinity, all to the praise of God and the perfection of the creature.

  13. Vegetation anomalies associated with the ENSO phenomenon in the Cauca river valley, Colombia

    J. M. Valencia

    2017-12-01

    Full Text Available The main factors affecting the production and yield of sugarcane are variety, agronomic management, soil type and climate, of which the first three there is some control, while the climate is one factor of which you cannot have any control, therefore, it should be monitored. Colombia, being located in the equatorial pacific, is affected by two atmospheric oceanic phenomena known as “El Niño” and “La Niña”, which make up the climatic phenomenon of ENSO (El Niño-Southern Oscillation and affect the quantity and the number of days with rainfall and influences the production of sugarcane. The objective of this work is to identify spatially and temporally the zones with greater and lower impact of the ENSO phenomenon in the cultivation of sugarcane in Colombia through the use of the Standard Vegetation Index (SVI and the Rainfall Anomally Index (RAI using EVI/MODIS images and precipitation data from meteorological stations on a quarterly basis for the period 2000-2015. A similar trend was found between both indices in the “El Niño” and “Neutral” seasons, while in the “La Niña” season the RAI tended to rise while the SVI decreased when the RAI was very high, this tendency being much more marked in areas with floods caused by the overflow of the main rivers. In addition, a comparison was made between the SVI index and a productivity anomaly index (IAP, finding a direct correlation between both (R2 = 0.4, p<0.001. This work showed that through the use of vegetation indexes, a temporal analysis of the impact of climate on an agricultural crop can be carried out, especially with ENSO conditions.

  14. Global warming

    Houghton, John

    2005-01-01

    'Global warming' is a phrase that refers to the effect on the climate of human activities, in particular the burning of fossil fuels (coal, oil and gas) and large-scale deforestation, which cause emissions to the atmosphere of large amounts of 'greenhouse gases', of which the most important is carbon dioxide. Such gases absorb infrared radiation emitted by the Earth's surface and act as blankets over the surface keeping it warmer than it would otherwise be. Associated with this warming are changes of climate. The basic science of the 'greenhouse effect' that leads to the warming is well understood. More detailed understanding relies on numerical models of the climate that integrate the basic dynamical and physical equations describing the complete climate system. Many of the likely characteristics of the resulting changes in climate (such as more frequent heat waves, increases in rainfall, increase in frequency and intensity of many extreme climate events) can be identified. Substantial uncertainties remain in knowledge of some of the feedbacks within the climate system (that affect the overall magnitude of change) and in much of the detail of likely regional change. Because of its negative impacts on human communities (including for instance substantial sea-level rise) and on ecosystems, global warming is the most important environmental problem the world faces. Adaptation to the inevitable impacts and mitigation to reduce their magnitude are both necessary. International action is being taken by the world's scientific and political communities. Because of the need for urgent action, the greatest challenge is to move rapidly to much increased energy efficiency and to non-fossil-fuel energy sources

  15. The Takete-Maluma phenomenon in autism spectrum disorders.

    Occelli, Valeria; Esposito, Gianluca; Venuti, Paola; Arduino, Giuseppe Maurizio; Zampini, Massimiliano

    2013-01-01

    It has been reported that people tend to preferentially associate phonemes like /m/, /l/, /n/ to curvilinear shapes and phonemes like /t/, /z/, /r/, /k/ to rectilinear shapes. Here we evaluated the performance of children/adolescents with autism spectrum disorders (ASD) and neurotypical controls in this audiovisual congruency phenomenon. Pairs of visual patterns (curvilinear vs rectilinear) were presented to a group of ASD participants (low- or high-functioning) and a group of age-matched neurotypical controls. Participants were asked to associate each item to non-meaningful phoneme clusters. ASD participants showed a lower proportion of expected association responses than the controls. Within the ASD group the performance varied as a function of the severity of the symptomatology. These data suggest that children/adolescents with ASD show, although at different degrees as a function of the severity of the ASD, lower phonetic-iconic congruency response patterns than neurotypical controls, pointing to poorer multisensory integration capabilities.

    2012-01-01

    In this paper, we visualize plasma collision phenomenon based on XYT-space (space and time) volume data for supporting research in plasma physics. We create 3D volume data in the XYT-space by piling up a time series of XY-plane photo images taken in experiment. As a result, we can visualize as one still image all the time behavior of the plasma plume. Besides, we adopt 'fused' visualization based on particle based rendering technique. Using that technique, we can easily fuse volume rendering different materials, and compare physics of different elements in flexible ways. In addition, we propose the method to generate pseudo-3D images from pictures shoot by ICCD of two perspectives on the upper and side. (author)

  18. Violence against women: the phenomenon of workplace violence against nurses.

    Child, R J Howerton; Mentes, Janet C

    2010-02-01

    Registered nurses have been the recipients of an alarming increase in workplace violence (WPV). Emergency and psychiatric nurses have been found to be the most vulnerable and yet few solid reporting procedures exist to fully account for a true number of incidents. Further compounding the problem is the lack of a standard definition of violence to guide reporting procedures, interventions, legislation, and research. While there are certain risk factors that not only predispose the nurse and the patient to WPV, research continues to attempt to parse out which risk factors are the key determinants of WPV and also which interventions prove to be significant in reducing WPV. The nursing shortage is expected only to increase; recruitment and retention of qualified staff members may be deterred by WPV. This necessitates focused research on the phenomenon of workplace violence in health care.

  19. Phenomenon in the Evolution of Voles (Mammalia, Rodentia, Arvicolidae

    Rekovets L. I.

    2017-04-01

    Full Text Available This paper presents analytical results of the study of adaptatiogenesis within the family Arvicolidae (Mammalia, Rodentia based of morphological changes of the most functional characters of their masticatory apparatus — dental system — through time. The main directions of the morphological differentiation in parallel evolution of the arvicolid tooth type within the Cricetidae and Arvicolidae during late Miocene and Pliocene were identified and substantiated. It is shown that such unique morphological structure as the arvicolid tooth type has provided a relatively high rate of evolution of voles and a wide range of their adaptive radiation, as well as has determined their taxonomic and ecological diversity. The optimality of the current state of this group and evaluation of evolutionary prospects of Arvicolidae were presented and substantiated here as a phenomenon in their evolution.

  20. Rational use of calcium-channel antagonists in Raynaud's phenomenon.

    Sturgill, M G; Seibold, J R

    1998-11-01

    Raynaud's phenomenon (RP) is a peripheral circulatory disorder characterized by sudden episodes of digital artery spasm, often precipitated by cold temperature or emotional stress. Although the cause of RP is not fully known, it appears to involve inappropriate adrenergic response to cold stimuli. Treatment of RP is conservative in most patients, but in patients with severe disease includes the use of agents that promote digital vasodilation. The calcium-channel antagonists, particularly the dihydropyridine derivative nifedipine, are the most thoroughly studied drug class for the treatment of RP. Approximately two thirds of patients respond favorably, with significant reductions in the frequency and severity of vasospastic attacks. Nifedipine use is often limited by the appearance of adverse vasodilatory effects such as headache or peripheral edema. The newer second-generation dihydropyridines such as amlodipine, isradipine, nicardipine, and felodipine also appear to be effective in patients with RP and may be associated with fewer adverse effects.

    A 57-year-old right-handed woman with a history of left frontal lobe stroke had experienced episodes of language-expression difficulty followed by paraphasia lasting for approximately 30 seconds two years earlier. She was diagnosed with left frontal lobe epilepsy, and a lamotrigine regimen was initiated. This treatment had to be stopped five weeks after initiation because she developed a rash, and her drug lymphocyte stimulation test result was positive. Interestingly, she has since remained seizure free without requiring any antiepileptic medications. This adult case with a peculiar clinical course provides support for the hypothesis of immunomodulation process involvement in epilepsy, a phenomenon that was previously mainly seen in pediatric patients.

    Controlled depolymerization of cellulose is essential for the production of valuable cellooligosaccharides and cellobiose from lignocellulosic biomass. However, enzymatic cellulose hydrolysis involves multiple synergistically acting enzymes, making difficult to control the depolymerization process and generate desired product. This work exploits the varying adsorption properties of the cellulase components to the cellulosic substrate and aims to control the enzyme activity. Cellulase adsorption was favored on pretreated cellulosic biomass as compared to synthetic cellulose. Preferential adsorption of exocellulases was observed over endocellulase, while β-glucosidases remained unadsorbed. Adsorbed enzyme fraction with bound exocellulases when used for hydrolysis generated cellobiose predominantly, while the unadsorbed enzymes in the liquid fraction produced cellooligosaccharides majorly, owing to its high endocellulases activity. Thus, the differential adsorption phenomenon of the cellulase components can be used for the controlling cellulose hydrolysis for the production of an array of sugars.

  3. Same-sex marriage: a new social phenomenon.

    Chamie, Joseph; Mirkin, Barry

    2011-01-01

    Same-sex marriage (SSM) is a new social phenomenon. In modern times SSM did not exist until the 21st century when an increasing number of countries began permitting same-sex couples to marry legally. This study presents statistical and related evidence concerning SSM worldwide, with special attention to the United States, where SSM has evolved into a major political and legal issue. In addition to examining data on levels and trends, differentials between men and women are investigated. The study also considers common arguments for and against SSM and likely changes in laws and policies that may occur. Although same-sex marriage now exists in a small number of countries and US states, its consequences and implications are being felt far beyond the borders of those countries and areas. In coming years same-sex marriage will remain a controversial and salient part of the legal, political, and cultural landscape, locally, nationally, and internationally.

    The numerical simulation of the discharge inception is an active field of applied physics with many industrial applications. In this work we focus on the drift-reaction equation that describes the electron avalanche. This phenomenon is one of the basic building blocks of the streamer model. The main difficulty of the electron avalanche equation lies in the fact that the reaction term is positive when a high electric field is applied. It leads to exponentially growing solutions and this has a major impact on the behavior of numerical schemes. We analyze the stability of a reference finite volume scheme applied to this latter problem. The stability of the method may impose a strict mesh spacing, therefore a proper stabilized scheme, which is stable whatever spacing is used, has been developed. The convergence of the scheme is treated as well as some numerical experiments.

  5. Retrospective Revaluation: The Phenomenon and Its Theoretical Implications

    Miller, Ralph R.; Witnauer, James E.

    2015-01-01

    Retrospective revaluation refers to an increase (or decrease) in responding to conditioned stimulus (CS X) as a result of decreasing (or increasing) the associative strength of another CS (A) with respect to the unconditioned stimulus (i.e., A-US) that was previously trained in compound with the target CS (e.g., AX−US or just AX). We discuss the conditions under which retrospective revaluation phenomena are most apt to be observed and their implications for various models of learning that are able to account for retrospective revaluation (e.g., Dickinson and Burke, 1996; Miller and Matzel, 1988; Van Hamme and Wasserman, 1994). Although retroactive revaluation is relatively parameter specific, it is seen to be a reliable phenomenon observed across many tasks and species. As it is not anticipated by many conventional models of learning (e.g., Rescorla and Wagner, 1972), it serves as a critical benchmark for evaluating traditional and newer models. PMID:26342855

  6. Molecular bases of cellular senescence: Hayflick phenomenon 50 years later

    Patrycja Sosińska

    2016-03-01

    Full Text Available Normal human somatic cells have strictly limited proliferative capacity and reach a state of senescence when it becomes exhausted. It is believed that senescence is a response to extensive and irreparable DNA injury, localized in telomeric and/or non-telomeric regions of the genome. Main cause of this damage is oxidative stress, increasing due to deteriorated function of mitochondria. Senescent cells accumulate in tissues during aging, which is causatively linked with the development of various pathologies in elderly individuals, including cancer. This paper, prepared exactly 50 years after Leonard Hayflick’s discovery of the relationship between cellular senescence and organismal aging is aimed at presenting the current knowledge about molecular determinants of senescence, with particular emphasis paid to the role of oxidative stress, effectors of senescence at the level of cell cycle, markers of this phenomenon, and the effect of senescent cells on the development of certain age-related diseases.

  7. Condensation in a capped capillary is a continuous critical phenomenon.

    Parry, A O; Rascón, C; Wilding, N B; Evans, R

    2007-06-01

    We show that condensation in a capped capillary slit is a continuous interfacial critical phenomenon, related intimately to several other surface phase transitions. In three dimensions, the adsorption and desorption branches correspond to the unbinding of the meniscus from the cap and opening, respectively, and are equivalent to 2D-like complete-wetting transitions. For dispersion forces, the singularities on the two branches are distinct, owing to the different interplay of geometry and intermolecular forces. In two dimensions we establish precise connection, or covariance, with 2D critical-wetting and wedge-filling transitions: i.e., we establish that certain interfacial properties in very different geometries are identical. Our predictions of universal scaling and covariance in finite capillaries are supported by extensive Ising model simulation studies in two and three dimensions.

  8. Cell Competition: Roles and Importance as a Central Phenomenon.

    Patel, Manish; Antala, Bhavesh; Shrivastava, Neeta

    2015-01-01

    Cell competition is a type of short-range cell-cell interaction first observed in Drosophila melanogaster. In two heterogeneous cell populations, cells that have a higher fitness level would have a competitive advantage and grow at the cost of neighbor cells that have comparatively lower fitness. This interaction is due to differences in expression levels of a specific protein in the two cell populations, and it is known as cell competition. In this review, we have studied recent findings of cell competition in different biological processes in Drosophila as well as mammalian systems. The purpose of this review is to collate important studies of competitive cell interactions, and to understand its roles and importance as a central phenomenon. This review provides evidence of the relevance of cell competition in various physiological and pathological conditions, such as size control in organ development, stem cell maintenance, tissue repair, organ regeneration, aging, formation of memory, and cancer.

  9. Aggregation-induced emission: phenomenon, mechanism and applications.

    Hong, Yuning; Lam, Jacky W Y; Tang, Ben Zhong

    2009-08-07

    It is textbook knowledge that chromophore aggregation generally quenches light emission. In this feature article, we give an account on how we observed an opposite phenomenon termed aggregation-induced emission (AIE) and identified the restriction of intramolecular rotation as a main cause for the AIE effect. Based on the mechanistic understanding, we developed a series of new fluorescent and phosphorescent AIE systems with emission colours covering the entire visible spectral region and luminescence quantum yields up to unity. We explored high-tech applications of the AIE luminogens as, for example, fluorescence sensors (for explosive, ion, pH, temperature, viscosity, pressure, etc.), biological probes (for protein, DNA, RNA, sugar, phospholipid, etc.), immunoassay markers, PAGE visualization agents, polarized light emitters, monitors for layer-by-layer assembly, reporters for micelle formation, multistimuli-responsive nanomaterials, and active layers in the fabrication of organic light-emitting diodes.

  11. Coupling Phenomenon in Diode with Dielectric Gridded Cathode

    Lahav, A.; Berezovsky, V.; Schachter, L.

    1999-01-01

    We investigated the current characteristic in a vacuum diode with a Gridded cathode. The grid is located on a top of a Ferro - Electric disk with a uniform cathode on its back side. We found experimental evidence that the current in such a system exceeds Child - Langmuir limit, in agreement with results reported in [1]. Explanations to this phenomenon were given in term of the non-linear characteristic of the ferro - electric ceramic or by plasma-assisted emission and gap closure. Recently [2] it has been shown theoretically that electrostatic coupling between the dielectric disk and the vacuum gap is directly responsible to the excess of current. We shall report experimental results that may support this possibility

  12. The phenomenon of voltage controlled switching in disordered superconductors

    Ghosh, Sanjib; De Munshi, D

    2014-01-01

    The superconductor-to-insulator transition (SIT) is a phenomenon occurring in highly disordered superconductors and may be useful in the development of superconducting switches. The SIT has been demonstrated to be induced by different external parameters: temperature, magnetic field, electric field, etc. However, the electric field induced SIT (ESIT), which has been experimentally demonstrated for some specific materials, holds particular promise for practical device development. Here, we demonstrate, from theoretical considerations, the occurrence of the ESIT. We also propose a general switching device architecture using the ESIT and study some of its universal behavior, such as the effects of sample size, disorder strength and temperature on the switching action. This work provides a general framework for the development of such a device. (paper)

  13. Phenomenon of adaptive response of cells in radiobiology

    Fillipovich, I.V.

    1991-01-01

    Consideration is given to various adaptive reactions to low-level radiation, their association with an absorbed dose, dose rate, radiation quality and time-interval between exposures, as well as with a cell cycle phase. Possible mechanisms of the adaptive response and the character and role of DNA damages, that can induce gene expression of the adaptive response, are discussed. The data on the influence of a preliminary long-term exposure to low-level radiation on the radiosensitivity of biological objects are analyzed with due regard for the adaptive cell response. It is concluded that the adaptive response of cells to ionizing radiation is a particular case of the phenomenon of cell adaptation of the effect of genotoxic factors of the environment

  14. Parallels in Communication and Navigation Technology and Natural Phenomenon

    Romanofsky, Robert

    2017-01-01

    The premise is more than art imitates life, or technology imitates nature it is a nascent step to see how we might be unwittingly inspired and influenced. An example that might immediately come to mind is a starling murmuration (a phenomenon called scale-free correlation) and Intels recent Coachella music festival drone performance. Superconductivity is a macroscopic manifestation of a quantum phenomenon - choreographed electrons (i.e. an electron murmuration) that enable astonishing devices. There is indeed an intimate connectedness between biology and electromagnetism. Our brains are complex neural circuits generating magnetic fields with a magnitude around 100 femtoTesla (roughly one billion times weaker than a typical magnet used to tack notes to a refrigerator door). Migratory birds navigate by orienteering with respect to the Earth's magnetic field. Electromagnetic field therapy is used in orthopedics to aid in bone repair. The electric eel generates a large electric field for self-defense. Sharks apparently detect extremely weak electric fields for finding prey. And so on. There are similarities between the way a field of wheat responds to a breeze and the natural restoring forces of a semiconductor crystal. And waves in a slowly moving river can lap backwards against a peninsular shoreline mimicking a diffraction effect. Getting back to the introductory sentence and mysterious links over cosmic distances, in August 2016, China launched the Quantum Experiments at Space Scale (QUESS) satellite. The technology is based on a non-linear crystal that produces pairs of entangled photons whose attributes apparently remain entwined regardless of how far apart they are separated. This paper will, no doubt superficially, attempt to enumerate and examine these types of connections and parallelisms.

  15. Suicide tourism: a pilot study on the Swiss phenomenon.

    Gauthier, Saskia; Mausbach, Julian; Reisch, Thomas; Bartsch, Christine

    2015-08-01

    While assisted suicide (AS) is strictly restricted in many countries, it is not clearly regulated by law in Switzerland. This imbalance leads to an influx of people-'suicide tourists'-coming to Switzerland, mainly to the Canton of Zurich, for the sole purpose of committing suicide. Political debate regarding 'suicide tourism' is taking place in many countries. Swiss medicolegal experts are confronted with these cases almost daily, which prompted our scientific investigation of the phenomenon. The present study has three aims: (1) to determine selected details about AS in the study group (age, gender and country of residence of the suicide tourists, the organisation involved, the ingested substance leading to death and any diseases that were the main reason for AS); (2) to find out the countries from which suicide tourists come and to review existing laws in the top three in order to test the hypothesis that suicide tourism leads to the amendment of existing regulations in foreign countries; and (3) to compare our results with those of earlier studies in Zurich. We did a retrospective data analysis of the Zurich Institute of Legal Medicine database on AS of non-Swiss residents in the last 5 years (2008-2012), and internet research for current legislation and political debate in the three foreign countries most concerned. We analysed 611 cases from 31 countries all over the world. Non-terminal conditions such as neurological and rheumatic diseases are increasing among suicide tourists. The unique phenomenon of suicide tourism in Switzerland may indeed result in the amendment or supplementary guidelines to existing regulations in foreign countries.

  16. Phenomenon of quantum low temperature limit of chemical reaction rates

    Gol'danskij, V.I.

    1975-01-01

    The influence of quantum-mechanical effects on one of the fundamental laws of chemical kinetics - the Arrhenius law - is considered. Criteria characterising the limits of the low-temperature region where the extent of quantum-mechanical tunnelling transitions exceeds exponentially the transitions over the barrier are quoted. Studies of the low-temperature tunnelling of electrons and hydrogen atoms are briefly mentioned and the history of research on low-temperature radiation-induced solid-phase polymerisation, the development of which led to the discovery of the phenomenon of the low-temperature quantum-mechanical limit for the rates of chemical reactions in relation to the formaldehyde polymerisation reaction, is briefly considered. The results of experiments using low-inertia calorimeters, whereby it is possible to determine directly the average time (tau 0 ) required to add one new link to the polymer chain of formaldehyde during its polymerisation by radiation and during postpolymerisation and to establish that below 80K the increase of tau 0 slows down and that at T approximately equal to 10-4K the time tau 0 reaches a plateau (tau 0 approximately equals 0.01s), are described. Possible explanations of the observed low-temperature limit for the rate of a chemical reaction are critically examined and a semiquantitative explanation is given for this phenomenon, which may be particularly common in combined electronic-confirmational transitions in complex biological molecules and may play a definite role in chemical and biological evolution (cold prehistory of life)

    2015-04-01

    Full Text Available Labor market activity may have an effect on global economy competitiveness. This issue has been described as "labor market efficiency" (LME, which is a constituent of The Global Competitiveness Index published by The World Economic Forum (WEF. The article's purpose is to clarify the phenomenon of LME and explain the mechanisms which help the constituents affect economy competitiveness. The structure of LME points at the meaning of labor market regime, especially after considering the fact that European Union countries operate within various models of regime. The analysis of the LME diversity may help determine what type of labor market regimes are most efficient in enhancing economy competitiveness

  19. On the Force Drop Off Phenomenon in Shaker Testing in Experimental Modal Analysis

    Paulo Sergio Varoto

    2002-01-01

    Full Text Available The Electrodynamic Vibration Exciter (shakers has been one of the most employed excitation sources in modal tests. The shaker is an electromechanical device that provides a mechanical motion due to the input signal sent to its coil. Despite being widely used, it is well known that the shaker interacts with the structure under test. In particular, when the structure passes through a given resonance, the force delivered by the shaker abruptly decreases, causing the so called drop off phenomenon. This paper aims to study this force drop off phenomenon in the single shaker modal testing. Analytical models are developed to help in understanding the physical principles involved in the interaction between the shaker and the structure under test. Experimental analyses are performed using different shakers as well as excitation signals, in order to evaluate the effects of the input signal, as well as the power amplifier operational modes, on the structure dynamics. Preliminary tests revealed that significant distortions might occur during vibration tests using shakers and these distortions significantly affect the determination of the structure response.

  20. The Labor Market from Romania from the Perspective of Migration Phenomenon

    Constantin Georgescu

    2017-12-01

    Full Text Available Population migration is a real phenomenon that has amplified over the last two decades and will continue to grow as major disparities between regions develop. There are many reasons that generate the trend of population movement. The reasons/ motive that are frequently invoked are the conflictual situation related issues that primarily affect individual security, political and social fragility, economic instability with effects in all areas of activity, degradation of living conditions, and the high risk of terrorism in certain areas. The population migration is not necessarily a bad thing if we are looking through the perspective of chances it offers to both people and the economy as a whole, being also an important factor for the growth of national and international trade. But, the lack of some decisions to control this phenomenon creates long-term imbalances. These imbalances are already extremely visible in the Romanian labor market. Numerous work field have a major staff lack and are need of solutions for doing business under normal conditions. Therefore, the present paper aims at highlighting the main features of the labor market, the country's risks, as well as identifying viable solutions for reducing economic and social imbalances.

  1. Designing a Qualitative Model of Doping Phenomenon Effect on Sport Marketing in Iran

    Jasem Manouchehri

    2016-10-01

    Full Text Available There a number of factors effecting consumers' purchase behavior. It is believed that celebrities can effect selling positively by transferring their popular image to the endorsed product. But, it is heard lots about excommunicate behaviors in the sport world today. Disclosure of the recent doping affairs relating to Lance Armstrong's seven wins in Tour De France is just one among many spectacular and also negative cases. The main aim of the present paper was to explore the effect of doping phenomenon on sport marketing. Depth interviews data were analyzed in three phases: open coding, axial coding, and selective coding. 297 open codes were achieved by 18 interviews. Grouping axial codes in each case and comparing, all gained codes can be divided in five groups: brand image (athlete and endorsed product brands images, moral reasoning (moral coupling, moral decoupling, and moral rationalization, consumer behavioral consequences (word of mouth, purchasing intention, and brand loyalty, attitude change (attitudes change toward athlete and brand, and moral emotions (moral evaluation, contempt, anger, disgust, and sympathy. The proposed qualitative model for the effect of doping phenomenon on sport marketing in Iran illustrated that moral emotions and product brand image affected by the doped athlete brand image and it resulted in attitudes change toward endorser athlete and endorsed brand and negative consumer behavioral consequences, however, moral reasoning strategies emerged by cognitive dissonance might protect consumers behavior from negative effects.

  2. [Contributions to the psychodynamic approach to understanding the phenomenon of music].

    Giglio, J S; Giglio, Z G

    1980-12-01

    Based on different writings from different periods, this article gives us some of the psychodinamic view of musical phenomenon. It is divided in three parts. 1. The initial one is about general aspects of musical phenomenon. Music has a hihg power of symbolization, due to its ambiguity and simultaneity of elements. It can make a change on the common state of consciousness. Music also can influence on the Ego's cognitive style. Music has relationship with both the Ego's dissociative function and Ego's integrative function. 2. The secon part refers to the affective nature of music. Music release libidinal energy mainly through rhythm; for exemple we see the link between and dance in primitive societies. It also gives expression for emotional life, and arouses emotions too. 3. The third part refers to structural and functional aspects of music. This last part talks about the role of music to the listener and to the creative musician; it presents an analogy between the structure of the music and structure of the dreams. The joy of music involves the whole personality and music may be used to expand the Self.

    2012-03-01

    'Tooth worm' is a traditional belief about the pathogen of dental caries (tooth decay). Nevertheless, in our previous study, parental 'tooth worm' belief was linked to a reduced caries risk of their children. This study aimed to further characterize the impact of parental 'tooth worm' belief on their children's caries experience and its psychobehavioural mechanisms. analytic observational study. Thirteen randomly selected kindergartens in Singapore. 1,782 preschoolers aged 3-6 years. Each child received an oral examination and microbiological tests. Parents completed a self-administered questionnaire on their socio-demographic background, oral health knowledge/attitude and child's oral health habits. Multivariate analysis confirmed a reduced chance of 'high caries rate' (number of affected teeth > 2) among children whose parents held the 'tooth worm' belief (Odds Ratio = 0.41; 95% Confidence Interval = 0.19-0.89). With such perception among parents, children brushed their teeth more frequently (p = 0.042). Since no difference in oral hygiene was observed, the health benefit of the "tooth worm" perception may be acquired through the delivery of fluoride (an agent with proven anti-caries effect) during frequent toothbrushing episodes. This study revealed a 'tooth worm' phenomenon, indicating that parental 'tooth worm' belief is associated with early establishment of regular toothbrushing habit and reduction of dental caries in children. This phenomenon and its psychobehavioural mechanisms, enriching our understanding of oral health behaviours, have implications for effective health education.

The content of global strategy can contain five key elements, while the process of global strategy can have six major stages. These are expounded below. Global strategy is influenced...... by rich and complementary local contexts with diverse resource pools and game rules at the national level to form a broad ecosystem at the global level. Further, global strategy dictates the interaction or balance between different entry strategies at the levels of internal and external networks....

  5. Effects of linear and nonlinear time-delayed feedback on the noise-enhanced stability phenomenon in a periodically driven bistable system

    Jia, Zheng-Lin; Mei, Dong-Cheng

    2011-01-01

    We investigate numerically the effects of time delay on the phenomenon of noise-enhanced stability (NES) in a periodically modulated bistable system. Three types of time-delayed feedback, including linear delayed feedback, nonlinear delayed feedback and global delayed feedback, are considered. We find a non-monotonic behaviour of the mean first-passage time (MFPT) as a function of the delay time τ, with a maximum in the case of linear delayed feedback and with a minimum in the case of nonlinear delayed feedback. There are two peculiar values of τ around which the NES phenomenon is enhanced or weakened. For the case of global delayed feedback, the increase of τ always weakens the NES phenomenon. Moreover, we also show that the amplitude A and the frequency Ω of the periodic forcing play an opposite role in the NES phenomenon, i.e. the increase of A weakens the NES effect while the increase of Ω enhances it. These observations demonstrate that the time-delayed feedback can be used as a feasible control scheme for the NES phenomenon

  7. Reaktualisasi Strategi Pendidikan Islam: Ikhtiar Mengimbangi Pendidikan Global

    M. Sobry

    2014-06-01

    Full Text Available Abstract: Globalization is inevitable phenomenon that may cause anxiety amongst countries, such as Indonesia, that still preserve their culture, ethics and religious values because it always introduces new things that are not easily adjusted to regional or local contexts. Globalization as it is reflected in rapid change and transformation in technology has affected most of human’s life, including education. Globalized education is the one that is characterized by global and transnational elements in its basic structure, for example, the use of information technologies and digital media that have both positive and negative impacts. However, for Indonesia, whose majority population is Islam, globalization is not a threat, which should be evaded. What needs to do is to integrate Islamic concepts and values in it. Globalization and its type of education that looks contrary to religious norms will no longer become a menace if it is strengthened with religious values.    Abstrak: Globalisasi merupakan fenomena kekinian yang terkadang dipandang sebagai momok dalam konteks bangsa, seperti Indonesia, yang berhasrat kuat melestarikan nilai adat, budaya, moral, dan nilai agama. Tulisan ini mencermati globalisasi yang memengaruhi dunia pendidikan sebagaimana terlihat pada semakin luasnya penggunaan media digital dengan semua manfaat dan mudarat yang menyertainya. Penulis berpendapat bahwa fenomena itu semestinya dipandang wajar dan dihadapi dengan lapang dada. Namun ia harus diimbangi dengan konsep-konsep islami dan diperkuat dengan strategi islami pula. Islam memiliki konsep moralitas dan etika yang komprehensif untuk diaktualisasikan dalam konteks arus globalisasi. Oleh karena itu, tidak ada jalan lain untuk mengimbangi pendidikan global saat ini kecuali dengan kembali kepangkuan konsep-konsep pendidikan Islam. 

  8. Gemfibrozil pretreatment affecting antioxidant defense system and inflammatory, but not Nrf-2 signaling pathways resulted in female neuroprotection and male neurotoxicity in the rat models of global cerebral ischemia-reperfusion.

    Mohagheghi, Fatemeh; Khalaj, Leila; Ahmadiani, Abolhassan; Rahmani, Behrouz

    2013-04-01

    Two important pathophysiological mechanisms involved during cerebral ischemia are oxidative stress and inflammation. In pathological conditions such as brain ischemia the ability of free radicals production is greater than that of elimination by endogenous antioxidative systems, so brain is highly injured due to oxidation and neuroinflammation. Fibrates as peroxisome proliferator-activated receptor (PPAR)-α ligands, are reported to have antioxidant and anti-inflammatory actions. In this study, gemfibrozil, a fibrate is investigated for its therapeutic potential against global cerebral ischemia-reperfusion (I/R) injury of male and female rats. This study particularly has focused on inflammatory and antioxidant signaling pathways, such as nuclear factor erythroid-related factor (Nrf)-2, as well as the activity of some endogenous antioxidant agents. It was found that pretreatment of animals with gemfibrozil prior to I/R resulted in a sexually dimorphic outcome. Within females it proved to be protective, modulating inflammatory factors and inducing antioxidant defense system including superoxide dismutase (SOD), catalase, as well as glutathione level. However, Nrf-2 signaling pathway was not affected. It also decreased malondialdehyde level as an index of lipid peroxidation. In contrast, gemfibrozil pretreatment was toxic to males, enhancing the expression of inflammatory factors such as tumor necrosis factor-α, nuclear factor-κB, and cyclooxygenase-2, and decreasing Nrf-2 expression and SOD activity, leading to hippocampal neurodegeneration. Considering that gemfibrozil is a commonly used anti-hyperlipidemic agent in clinic, undoubtedly more investigations are crucial to exactly unravel its sex-dependent neuroprotective/neurodegenerative potential.

  9. Global Operations Networks in Motion

    Slepniov, Dmitrij; Jørgensen, Claus; Wæhrens, Brian Vejrum

    2009-01-01

    This paper addresses the phenomenon of global operations networks and how they change over time. The paper is based on the cases of three Danish companies and their global operations networks. It finds a number of common patterns highlighting some organisational effects and managerial challenges...... the companies face regarding rapid changes in their networks configurations and capabilities. The paper details the variables determining these changes and suggests how the on-going interplay between the focal organisation, its network partners, and their various contextual conditions can be approached....

  10. Globalization of healthcare.

    2012-05-01

    Globalization-the increasing transnational circulation of money, goods, people, ideas, and information worldwide-is generally recognized as one of the most powerful forces shaping our current and future history. How is it affecting healthcare, and in that context, what is the purpose and significance of Global Advances in Health and Medicine (GAHM), publisher of this journal? Our goal is not homogenization but rather to provide an opportunity for integration, convergence, and collaboration across cultures. By respecting and conserving the richness and diversity of each new medicine, we embrace globalization. Globalization is of course not new; it began in the Renaissance and particularly with the 15th- and 16th-century voyages of exploration by Columbus, Magellan, and others. Since the beginning of time, there have been interactions and exchanges among different peoples and cultures. However, the current magnitude of globalization is unprecedented and yet still expanding rapidly.

    Relationships between viruses and autoimmune diseases such as systemic lupus erythematosus (SLE) are still elusive. Recent reports demonstrated the association of some viral infections with peculiar clinical events in the general population, such as cytomegalovirus (CMV) with arterial damage and Parvovirus B19 (PV-B19) with hematologic abnormalities. We planned to look for this kind of viral imprinting in SLE, hypothesizing that traces of specific features of some viral infections might be found in some subsets of seropositive SLE patients. In 60 SLE patients recruited at our nephrologic center, serology for CMV, PV-B19, Epstein-Barr virus viral capsid antigen (EBV-VCA), Epstein-Barr nuclear antigen (EBNA) and Epstein-Barr virus early antigen (EBV-EA) was performed. chi2 and ANOVA were employed to compare the frequency and titers of antiviral antibodies in SLE patients with groups of transplant, hemodialysis and blood donor subjects. chi2, Fisher's test, Bonferroni and Scheffe's test were employed to compare the different biochemical/clinical features between seropositive and seronegative SLE patients. Univariate and multivariate analysis (logistic regression models) were employed to evaluate the odds ratio (OR) of different risk factors for vascular events (including Raynaud's phenomenon, deep venous thrombosis) and hematologic abnormalities (including severe anemia, leukopenia and thrombocytopenia). Anti-CMV (82%), anti-PV-B19 (60%), anti-EBV-VCA (92%) and EBV-EA (45%) IgG antibodies were frequent in SLE, with higher prevalence in comparison with the blood donor group and higher titers in comparison with transplant and hemodialysis groups. CMV seropositivity was a highly significant risk factor for Raynaud's phenomenon (OR +alpha in univariate and multivariate analysis = 13.51 using a correction of 0.5 in case of a zero event), but not for venous vascular events (OR = 1.31). An increased though not significant risk factor was found for antiphospholipid antibodies

  14. Forced Migration and Global Responsibility for Health Comment on "Defining and Acting on Global Health: The Case of Japan and the Refugee Crisis".

    Bozorgmehr, Kayvan; Razum, Oliver

    2016-11-05

    Forced migration has become a world-wide phenomenon in the past century, affecting increasing numbers of countries and people. It entails important challenges from a global health perspective. Leppold et al have critically discussed the Japanese interpretation of global responsibility for health in the context of forced migration. This commentary complements their analysis by outlining three priority areas of global health responsibility for European Union (EU) countries. We highlight important stages of the migration phases related to forced migration and propose three arguments. First, the chronic neglect of the large number of internally displaced persons (IDPs) in the discourses on the "refugee crisis" needs to be corrected in order to develop sustainable solutions with a framework of the Sustainable Development Goals (SDGs). Second, protection gaps in the global system of protection need to be effectively closed to resolve conflicts with border management and normative global health frameworks. Third, effective policies need to be developed and implemented to meet the health and humanitarian needs of forced migrants; at the same time, the solidarity crisis within the EU needs to be overcome. These stakes are high. EU countries, being committed to global health, should urgently address these areas. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

  16. Dynamics of the spirit possession phenomenon in Eastern Tanzania

    Marja-Liisa Swantz

    1976-01-01

    Full Text Available The discussion on the spirit possession phenomenon is related in this study to the more general question of the role of religious institutions as part in the development process of a people living in a limited geographical area of a wider national society. It is assumed that religion, like culture in general, has its specific institutional forms as result of the historical development of a society, but at the same time religion is a force shaping that history. People's cultural resources influence their social and economic development and form a potential creative element in it'. Some of the questions to be asked are: "How are specific religious practices related to the dynamics of change in the societies in question? What is the social and religious context in which the spirit possession phenomenon occurs in them? What social and economic relations get their expression in them? To what extent is spirit possession in this case a means of exerting values and creatively overcoming a crisis or conflict which the changing social and economic relations impose on the people? The established spirit possession cults are here seen as the institutional forms of religious experience. At the same time it becomes evident that there is institutionalization in process as well as deinstitutionalization of spirit possession where it occurs outside established institutional forms. Institution is taken as a socially shared form of behaviour the significance of which is commonly recognized by those who share it. By the term spirit possession cult is meant a ritual form of spirit possession of a group which is loosely organized and without strict membership. The context of the study is four ethnic groups in Eastern Tanzania, near the coast of the Indian Ocean. The general theme of the project is The Role of Culture in the Restructuring of Tanzanian Rural Areas. The restructuring refers to a villagisation programme carried out in the whole country.

  17. The e-book phenomenon: a disruptive technology

    Tom D. Wilson

    2014-03-01

    Full Text Available The emergence of the e-book as a major phenomenon in the publishing industry is of interest, world-wide. The English language market, with Amazon.com as the major player in the market may have dominated attention, but the e-book has implications for many other languages and book markets. The pre-e-book publishing world can be seen as a system in which authors delivered texts to publishers, who evaluated, edited, printed and distributed the published text to bookshops and thence to libraries and individual readers. This process has been going on since Gutenberg’s re-invention of movable type in about 1439 (following its original invention in China in the 9th century, and the use of metallic type in Korea in 1234, in other words, for about the past 550 years. The invention of movable type was an instance of a disruptive technology: eventually putting monastic scribes out of business altogether. Similarly, the e-book has the potential to disrupt the processes for the production, distribution and use of authorial texts, and is already in the process of doing so. First, the phenomenon of self-publishing has emerged as a serious contender to the more formal process; secondly, publishers may derive significant economic benefit from the reduction in printing and distribution costs, as well as the ability to sell directly to the consumer through their own Websites; thirdly, the impact on booksellers may result in a further reduction in the number of independent stores – a decline already in process as a result of online bookselling; fourthly, user demand is resulting in libraries wrestling with the problems of how to manage e-books within their collection development and management processes; and, finally, the behaviour of readers is changing as the devices available for using e-books become more numerous and cheaper. Only someone blessed with absolute certainty in forecasting the future can know exactly how things will change, but there is little

  18. Aquatic Organic Matter Fluorescence - from phenomenon to application

    Reynolds, Darren

    2014-05-01

    The use of fluorescence to quantify and characterise aquatic organic matter in river, ocean, ground water and drinking and waste waters has come along way since its discovery as a phenomenon in the early 20th century. For example, there are over 100 papers published each year in international peer reviewed journals, an order of magnitude increase since a decade ago (see Figure taken from ISI database from 1989 to 2007 for publications in the fields of river water and waste water). Since then it has been extensively used as a research tool since the 1990's by scientists and is currently used for a wide variety of applications within a number of sectors. Universities, organisations and companies that research into aquatic organic matter have either recently readily use appropriate fluorescence based techniques and instrumentation. In industry and government, the technology is being taken up by environmental regulators and water and wastewater companies. This keynote presentation will give an overview of aquatic organic matter fluorescence from its conception as a phenomenon through to its current use in a variety of emerging applications within the sectors concerned with understanding, managing and monitoring the aquatic environment. About the Speaker Darren Reynolds pioneered the use of fluorescence spectroscopy for the analysis of wastewaters in the 1990's. He currently leads a research group within the Centre for Research in Biosciences and sits on the Scientific Advisory Board for the Institute of Bio-Sensing Technology at the University of the West of England, Bristol. He is a multidisciplinary scientist concerned with the development of technology platforms for applications in the fields of environment/agri-food and health. His current research interests include the development of optical technologies and techniques for environmental and biological sensing and bio-prospecting applications. He is currently involved in the development and use of synthetic biology

  19. Twinning in Zircon: Not a High-Pressure Phenomenon

    Jones, G. A.; Moser, D.; Shieh, S. R.; Barker, I.

    2017-12-01

    Microtwins in zircon are commonly found in shocked terrestrial and extraterrestrial samples and are potentially important for shock history and crater reconstruction. Twinning is easily observed with both the optical microscope and variety of electron beam techniques. Twinning as a deformation mechanism is consistent with the high strain rates generated during impact. No constitutive relationships, or even general limits on the physical conditions required for twinning in zircon are known, however. Present speculation on the critical quantity for twin formation, i.e. 10s of GPa of shock pressure (Moser et al. 2011, Timms et al., 2012), has no basis in the underlying mechanisms of twin nucleation, which are related to the motion of dislocations. This erroneous value is due to conflation of twinning sensu stricto with a phase transformation to reidite. Reidite occurs as twin-like lamellae occupying the {112} planes which are thought to be a mirror plane for twinning. We review the crystallographic theory of twinning in zircon. We then evaulate several theories on the nucleation of twins along with their necessary stresses involved. Our aim is to show that shock microtwins in zircon can be a `low pressure' shock phenomenon. This 'low pressure' hypothesis is supported by natural samples. These zircons are from the lower crust nearly 80 km from the centre of the Vredefort impact structure—the most distal zircon shock microstructures yet found in the lithosphere. Twins are present in 10% of the zircon grains greater than 50 µm in diameter. As an extensive, 'low pressure' phenomenon, twins are an easily recognized and potentially widespread record of Earth's impact history.Moser, D.E., Cupelli, C. L., Barker, I., Flowers, R.

    2011-01-01

    The concept of usability has become an increasingly important consideration in the design of all kinds of technology. As more products are aimed at global markets and developed through internationally distributed teams, usability design needs to be addressed in global terms. Interest in usability as a design issue and specialist area of research and education has developed steadily in North America and Europe since the 1980's. However, it is only over the last ten years that it has emerged as a global concern. Global Usability provides an introduction to the important issues in globalizing des

    2012-01-01

    The aim of this study was to explore smoking among adolescents and to examine the attitudes of parents to this patology. MATEIAL AND METHODS: the study included 180 adolescents of promary school and 40 parents.Research was conducted by questionnaire containing questions on smoking among youths., the avalibaility of and reasons for reaching for a cigarette. Parents also answered questions concerning knowledge about this pathology and how to deal with it. The study shows that 20% of sixth grade students of primary school has had a first initiation nicotine. The surveyed parents/carers feel that the biggest threat in the school environment is not smoking (12.5%), but drug abuse (80%). 31% of respondents believe that these phenomena are inherent. Parents/guardians are aware of the risks which are inherent to smoking, but do not know how to figh him. Pupils from Year 6 of primary school are exposed in school to smoke. There is a need for education of young people and parents of the dangers of smoking and prevention of this pathology. Parents do not know how to prevent smoking among adolescents and to turn to for help. Common activities at school, parents and local communities seem to be an alternative to this phenomenon.

  2. The dialectic in becoming a mother: experiencing a postpartum phenomenon.

    Sethi, S

    1995-01-01

    In this study of the phenomenon of the postpartum period grounded theory methodology was used to investigate the experiences of first-time mothers during the first three months following their deliveries. The sample consisted of 12 primipara women and 3 multipara women. The data were generated by using unstructured interviews and field notes. Each woman was interviewed twice, the first time between 2 and 3 weeks postpartum, and the second time between 10 and 12 weeks postpartum. The final data for analysis consisted of: data generated through interviews, field notes, and the narratives of four mothers found in the non-fiction literature. Constant comparative analysis resulted in the generation of four categories and corresponding subcategories. These were: (1) Giving of Self; (2) Redefining Self; (3) Redefining Relationships; and (4) Redefining Professional Goals. The categories were not mutually exclusive. All the categories converged to provide support for the core variable 'Dialectic in Becoming a Mother'. The dialectic perspective demonstrated that, in becoming mothers, the women experienced transition, contradictions, tensions and transformations. A theoretical model was developed to show relationships among these major concepts. The findings of this study will be useful in effecting change in the provision of care to postpartum women and their families.

  3. Cyberbullying: a 21st Century Health Care Phenomenon.

    Carter, Jemica M; Wilson, Feleta L

    2015-01-01

    This study examined bullying and cyberbullying prevalence among 367 adolescents 10 to 18 years of age who were attending schools and community organizations in suburban and urban neighborhoods in the Midwest United States. The correlational design investigated adolescents' daily use of technology that could be used to cyberbully peers, such as cell phones, computers, email, and the Internet. Results showed that 30% of participants had been bullied during school, and 17% had been cyberbullied, with online social networking sites the most common media employed (68%). The majority of participants owned or had access to computers (92%), email accounts (88%), social networking accounts (e.g., Facebook or MySpace) (82%), and cell phones (79%). Daily technology use included an average of two hours on a computer and a median of 71 text messages per day. Logistic regression analysis revealed no significant differences in bullying or cyberbullying prevalence based on location (urban or suburban) or demographic characteristics. Given the substantial presence of cyberbullying and the increase in technology use among adolescents in the 21st century, nurses need knowledge of the phenomenon to plan assessments in clinical practice. Early identification and assessment of cyberbullying victims and perpetrators, and development and implementation of effective interventions are needed to reduce this form of bullying among adolescents.

  4. Deadline rush: a time management phenomenon and its mathematical description.

    König, Cornelius J; Kleinmann, Martin

    2005-01-01

    A typical time management phenomenon is the rush before a deadline. Behavioral decision making research can be used to predict how behavior changes before a deadline. People are likely not to work on a project with a deadline in the far future because they generally discount future outcomes. Only when the deadline is close are people likely to work. On the basis of recent intertemporal choice experiments, the authors argue that a hyperbolic function should provide a more accurate description of the deadline rush than an exponential function predicted by an economic model of discounted utility. To show this, the fit of the hyperbolic and the exponential function were compared with data sets that describe when students study for exams. As predicted, the hyperbolic function fit the data significantly better than the exponential function. The implication for time management decisions is that they are most likely to be inconsistent over time (i.e., people make a plan how to use their time but do not follow it).

  5. Stress ratio determination from the core-disking phenomenon

    Lehnhoff, T.F.; Stefansson, B.; Thirumalai, K.

    1982-08-01

    The ability to predict in situ stress conditions from standard core samples offers planning and site-selection advantages for most underground facilities. This paper presents an empirical relation for estimating the horizontal to vertical stress ratio in basalt. The resulting estimates can then be used to help assess the extent to which measurement of in situ stress is required. The core disking phenomenon has long been used as an indicator of high in situ stress. It is concluded that disks form as the result of tensile failure initiation rather than shear failure initiation of the core. It is deduced that the tensile failure begins at the edge of the core and propagates toward the center in shear rather than beginning at the center and propagating outward. An empirical relation for horizontal to vertical stress ratio variation with depth has been developed and is shown to agree substantially with previous measured horizontal to vertical stress ratios for locations in several areas of the world. The stress-ratio predictions are justified based on finite-element studies using linear elastic analysis and also nonlinear (tension cut-off) analysis. Indications of fracture propagation paths were determined from the analyses. The shape of the predicted propagation path agrees well with physical observations

    Full Text Available The bullying phenomenon is characterized by aggression always unequal power and involves violence. This study aimed to identify the types of bullying (physical, verbal, psychological, material, virtual or sexual more prevalent in this population and compare bullying among adolescent males and females. We used a questionnaire prepared by the researcher. Participants were 309 students, 142 males and 167 females, from 6th to 8th grade from two schools, one state and one municipal. These results show 27% of participants were involved in episodes of bullying and that the most prevalent type of bullying was verbal, being appointed for 92% of girls and 84% boys; followed by psychological, indicated by 70% of girls and 53% boys. Physical bullying, had 46% of female and 44% male reports, the material was mentioned by 27% of girls and 16% boys. On sexual bullying type was greatest difference between the sexes, suffered by 38% of girls and 16% boys. Only 13% of girls and 12% boys, mentioned suffer the virtual bullying. Corroborating research area, in this study the highest percentage of victims were female and different from the literature girls reported being verbally abused more for boys than for girls.

    Branch occlusion of the anterior cerebral artery (ACA) is regarded as a part of Moyamoya disease. The purpose of this study is to define the ACA steal phenomenon (SP) in Moyamoya disease and to evaluate temporal changes according to the disease progression. From 139 Moyamoya patients we defined ACASP as narrowing of the ipsilateral A1-2 junction while preserving the anterior communicating artery and supplying the contralateral ACA cortical branches with the development of leptomeningeal collaterals by the ipsilateral middle cerebral artery into the hypoperfused ipsilateral ACA territory. Direction of the steal related to the stage in both hemispheres by Suzuki classification was statistically analyzed using the binomial test based on binomial distribution. Follow-ups of ACASP were evaluated in five patients. We identified ACASP in 13 (9%) patients (male:female=7:6, mean age 18 years, range: 2-58 years) of the 139 study patients. The presenting pattern was ischemic in 12 and hemorrhagic in one. The direction of SP occurred from the hemisphere in the lower to the higher stage of Suzuki classification (two-tail P value=0.0002). After revascularization surgery, ACASP disappeared or diminished. ACASP may occur in bilaterally different stages of Moyamoya disease as a transient self-adaptive process. It regresses after revascularization surgery. (orig.)

  8. Reconsolidation revisited: a review and commentary on the phenomenon.

    Moore, Jennifer L; Roche, Richard A P

    2007-01-01

    Consolidation and reconsolidation constitute a large proportion of current research into memory formation. The evidence in favour of the Consolidation Theory is widespread, on both the cellular and systems level. Research has indicated that consolidation and reconsolidation employ similar mechanisms; both consolidation and reconsolidation of memory require protein synthesis and glutaminergic input, and both seem to be associated with the hippocampal formation. Despite this, other data seem to argue that the two concepts are entirely separate processes. The great interest in this topic is shown in the proliferation of studies. The current literature has been subject to extensive and continual review. The current manuscript attempts to address the inconsistency in the consolidation-reconsolidation literature by providing a selective review of some of the most pertinent experimental work in both areas. The core question underpinning this review paper is whether reconsolidation is an entity distinct from consolidation, or merely an extension of the consolidation process. It is concluded that consolidation and reconsolidation may be distinct, albeit similar, processes, and that only a subset of the brain areas involved in consolidation are implicated in reconsolidation. In addition, with advances in our understanding of, and approach to these processes (i.e., incorporation of boundary conditions of reconsolidation into the design of contemporary studies and the increased awareness of the need to temper the interpretation of data emerging from studies employing divergent methodologies), it is suggested that future reconsolidation research may yield significant progress into the vast potential underpinning the reconsolidation phenomenon.

    Under some author's opinion the wind is not a periodical phenomenon and therefore it is more reasonable to invest in renewable periodical energies as tides. In this paper we have developed a computer application based in MatLab {sup copyright}, that through the FFT (Fast Fourier Transform) analyzes the variations of wind speed amplitude in the time and frequency domain. The data were sampled every 10 min in the period 2000-2008. The data come from 31 Automatic Meteorological Stations (EMAs), the country of Mexico and correspond one per state. The survey shows the representation of spectral-temporal surfaces to long time intervals, as one year or more and denotes seasonal envelopes that alter the pattern at certain times everyday. As a conclusion, the wind has an important periodical component for the country of Mexico, since the fundamental component of the wind speed represents a frequency of 1/24 h{sup -1} in a very accurate form throughout the time studied. To harness the wind potential of the country of Mexico it should be kept in mind that there is a minimum wind speed between 8 and 16 h and a maximum close to 24 h. (author)

  10. Raynaud's Phenomenon: a Brief Review of the Underlying Mechanisms

    Manal Fardoun

    2016-11-01

    Full Text Available Raynaud's phenomenon (RP is characterized by exaggerated cold-induced vasoconstriction. This augmented vasoconstriction occurs by virtue of a reflex response to cooling via the sympathetic nervous system as well as by local activation of α2C adrenoceptors (α2C-AR. In a cold-initiated, mitochondrion-mediated mechanism involving reactive oxygen species and the Rho/ROCK pathway, cytoskeletal rearrangement in vascular smooth muscle cells (VSMCs orchestrates the translocation of α2C-AR to the cell membrane, where this receptor readily interacts with its ligand. Different parameters are involved in this spatial and functional rescue of α2C-AR. Of notable relevance is the female hormone, 17β-estradiol, or estrogen. This is consistent with the high prevalence of RP in pre-menopausal women compared to age-matched males. In addition to dissecting the role of these various players, the contribution of pollution as well as genetic background to the onset and prevalence of RP are also discussed. Different therapeutic approaches employed as treatment modalities for this disease are also highlighted and analyzed. The lack of an appropriate animal model for RP mandates that more efforts be undertaken in order to better understand and eventually treat this disease. Although several lines of treatment are utilized, it is important to note that precaution is often effective in reducing severity or frequency of RP attacks.

  11. Pre-glow phenomenon origin and its scaling for ECRIS

    Izotov, I.; Sidorov, A.; Skalyga, V.; Zorin, V.

    2012-01-01

    Pre-glow is the multi-charged ion current burst that may occur at the beginning of the beam pulse. Pre-glow effect investigation is one of topical directions of ECR ion sources development at present. Pre-glow is of interest for efficient short-pulsed multicharged ion source creation. Particularly, such source of intense beams of short living radioactive isotopes multi-charged ions is one of key elements in 'Beta-Beam' European project. The use of Pre-glow-generating regime of an ECRIS operation is a promising way of pulsed high-intense multi-charged ion beams production with much shorter edges in comparison with usual operation regime. Numerical simulations made with the updated theoretical model allow authors to propose more physical and intuitive explanations of Pre-glow phenomenon origins. The obtained dependences of Pre-glow characteristics on experimental conditions offer a scaling for a wide range of ECRIS. The propose scaling demonstrates that an ECR source with plasma heating by radiation at frequency of 37 GHz and higher seems to be the most effective in terms of currents, pre-glow intensity and mean ion charge. The paper is followed by the slides of the presentation

  12. LONG-DISTANCE RUNNING AS A SOCIAL PHENOMENON

    Stankiewicz Blazej

    2012-04-01

    Full Text Available In recent years the leisure activities that do not require any special qualifications, equipment or talents have gained the greatest popularity. People living in a civilized, urbanized world full of growing problems need a form of escape from the daily routine, and running provides an excellent opportunity for this. Objective. The objective of the present paper was to characterize a small social group going in for recreational long-distance running. Detailed information gained this way might prove helpful when organizing leisure activities for people seeking new forms of recreation. Also, they might be a precious source of information for those who already practice and are looking for new solutions when developing their training loads. Materials and methods. A survey that was carried out included 68 competitors enrolled in the Metropolis marathon Bydgoszcz-Torun and running at the distances of 21,1km and 42,2km. The competitors in the 20 to 60 age bracket were examined. The research method applied was a survey questionnaire. Conclusions. Long-distance running is undoubtedly a developing social phenomenon that attracts more and more followers. The results presented might provide a valuable source of information for those who already practice and are looking for new solutions when developing their training loads.

  14. Ayn Rand phenomenon in contemporary social and ethical problems

    M. I. Korobko

    2014-03-01

    Full Text Available This paper attempts to give a general outline of the phenomenon of well­known American writer and philosopher Ayn Rand in contemporary social and ethical space. Application to the research of life, literary and philosophical heritage of the writer makes it possible to assess its impact on the current situation in politics and philosophy. Review of Ayn Rand’s artistic positions confirms her role as a landmark figure, who represented at that time the actual socio­cultural request of active man in contemporary philosophy and politics, “putting down” in literary form complex of philosophical questions to the level of the ordinary man. Ayn Rand is the focus of the social practices in which she was formed, lived and worked. The ideas of almost all philosophical subjects are presented in her works in a simple way, but they are fundamentally different from conventional notions of ethics, politics and philosophy in general, even the ideas of philosophers, whom she honored, such as Aristotle. That’s why modern philosophers are interested in studying her works now. After all, still there has no comprehensive academic analysis of her philosophical and scientific works of art.

  15. Cascade phenomenon against subsequent failures in complex networks

    Jiang, Zhong-Yuan; Liu, Zhi-Quan; He, Xuan; Ma, Jian-Feng

    2018-06-01

    Cascade phenomenon may lead to catastrophic disasters which extremely imperil the network safety or security in various complex systems such as communication networks, power grids, social networks and so on. In some flow-based networks, the load of failed nodes can be redistributed locally to their neighboring nodes to maximally preserve the traffic oscillations or large-scale cascading failures. However, in such local flow redistribution model, a small set of key nodes attacked subsequently can result in network collapse. Then it is a critical problem to effectively find the set of key nodes in the network. To our best knowledge, this work is the first to study this problem comprehensively. We first introduce the extra capacity for every node to put up with flow fluctuations from neighbors, and two extra capacity distributions including degree based distribution and average distribution are employed. Four heuristic key nodes discovering methods including High-Degree-First (HDF), Low-Degree-First (LDF), Random and Greedy Algorithms (GA) are presented. Extensive simulations are realized in both scale-free networks and random networks. The results show that the greedy algorithm can efficiently find the set of key nodes in both scale-free and random networks. Our work studies network robustness against cascading failures from a very novel perspective, and methods and results are very useful for network robustness evaluations and protections.

  16. A Plant's Response to Gravity as a Wave Guide Phenomenon

    Wagner, Orvin

    1997-11-01

    Plant experimental data provides a unifying wave theory (W-wave theory) for the growth and development of plants. A plant's response to gravity is an important aspect of this theory. It appears that a plant part is tuned to the angle with which it initially grew with respect to the gravitational field and changes produce correction responses. This is true because the velocity of W-waves (whose standing waves determine plant structure) within plant tissue is found to be different in different directions (angle a) with respect to the gravitational field. I found that there are preferred values of a, namely integral multiples of near 5 degrees for some plants. Conifers apparently are more sensitive to the gravitational field than deciduous trees, in the cases studied, so their structure is determined in more detail by the gravitational field. A plant's response to gravity appears to be a fundamental phenomenon and may provide a new model for gravity that can be experimentally verified in the laboratory. Along these same lines accelerometers placed in plant tissue indicate that plants produce gravity related forces that facilitate sap flow. See the

  17. Eating disorders: a hidden phenomenon in outpatient mental health?

    Fursland, Anthea; Watson, Hunna J

    2014-05-01

    Eating disorders are common but underdiagnosed illnesses. Help-seeking for co-occurring issues, such as anxiety and depression, are common. To identify the prevalence of eating problems, using the SCOFF, and eating disorders when screening positive on the SCOFF (i.e., ≥2), among patients seeking help for anxiety and depression at a community-based mental health service. Patients (N = 260) consecutively referred and assessed for anxiety and depression treatment were administered the SCOFF screening questionnaire and a semi-structured standardized diagnostic interview during routine intake. 18.5% (48/260) scored ≥2 on the SCOFF, indicating eating problems. Of these, 41% (19/48) met criteria for an eating disorder. Thus, overall, 7.3% (19/260) of the sample met criteria for a DSM-IV eating disorder. Those scoring ≥2 on the SCOFF were more likely to: be female (p = 0.001), younger (p = 0.003), and have a history of self-harm (p eating disorders are a hidden phenomenon in general outpatient mental health. By using a standardized diagnostic interview to establish diagnosis rather than self- or staff-report, the study builds on limited previous findings. The naturalistic study setting shows that screening for eating disorders can be easily built into routine intake practice, and successfully identifies treatment need.

  18. Magnetoresistance and magnetic breakdown phenomenon in amorphous magnetic alloys

    Chen Hui-yu; Gong Xiao-yu

    1988-01-01

    Transverse magnetoresistance in amorphous magnetic alloys (Fe/sub 1-//sub x/CO/sub x/) 82 Cu/sub 0.4/Si/sub 4.4/B/sub 13.2/ were measured at room temperature and in the magnetic field range 0--15 kOe. For large magnetic field, three different functional dependences of magnetoresistance on magnetic field strength have been found as follows: (1) Δrho/rho approaches saturation. (2) Δrho/rho increases proportionally to H 2 . (3) For x = 0.15, a sharp Δrho/rho peak appears at a certain magnetic field strength in spatial angular orientation of both magnetic field and electric currents. Case (3) is a magnetic breakdown phenomenon. Magnetic breakdown occurs at the gap between the spin-up and spin-down sheets of the Fermi surface. This gap is the spin-orbit gap and its magnitude is a sensitive function of magnetization. Hence the magnitude and width of the magnetoresistance peak and the magnetic field strength at the peak point are functions of angular orientation of both magnetic field and electric current

  19. CONSIDERATIONS ON THE DROUGHT PHENOMENON IN CLUJ COUNTY

    CORNEL BLAGA

    2011-03-01

    Full Text Available Considerations on the drought phenomenon in Cluj County. Cluj county area is 6674 km², and is located in the northwestern part of Romania. The climate is temperate continental with oceanic influences, relatively humid, but there are also periods of drought and even years with deficient rainfall, as there are periods of excess rainfall. Dryness and drought phenomena are caused by cosmic, climatic, hydrological (groundwater depth, the existence of surface water sources factors, features of the underlying surface, vegetation coverage, soil texture and structure. The relief determines a climate elevation with differences in terms of precipitation and temperatures quantities. To calculate the dryness degree of the climate at weather stations in the Cluj county, the Emmanuel de Martonne aridity index was used. Drought do not induce into the substrate the geomorphologic processes per se, however, they pave the way for starting the deflation process, surface erosion and ravine, by reducing the cohesion between the particles and the formation of deep cracks in the soil and even rock. In these climatic conditions, droughts are less frequent in the county of Cluj, in relation to the extra-Carpathian regions and are distributed unevenly across the county. The number of periods of drought decreases with the increase of the altitude, from an average of 2.6 drought periods a year at Dej (altitude of 232 m to an annual average of 0.3 draught periods at Vlădeasa Peak (altitude of 1836 m.

  20. The phenomenon of adolescents placing pressure on their parents.

    Bester, Garfield; Marais, Amanda C

    2014-01-01

    Parents are under pressure from their adolescent children if they, contrary to their own convictions, are compelled to bend rules or adapt decisions to submit to the demands of their children. The objective of this investigation was to determine which factors contribute to this phenomenon. The sample comprised 177 adolescents and their parents in the Mpumalanga province. Variables taken into account were individual factors (gender, age and personality of parents and adolescents); factors related to the family (family structure, working circumstances of parents, family relationships and birth order position of adolescents); developmental factors (identity formation of adolescents); and wider contextual factors (peer pressure during adolescence). From the parents' side factors such as self-concept, personality and parent-adolescent relationship explained almost 62% of the variance in the pressure that parents experience. Only one prominent adolescent factor could be identified, namely adolescent-parent relationship (seen from the adolescents' side). The results indicate that the pressure which parents encounter from their adolescent children is associated with parental variables rather than adolescent variables. Adolescents do not deliberately plan to place their parents under pressure, but factors on the parents' side create such a situation.

  1. CD3-positive B cells: a storage-dependent phenomenon.

    Angela Nagel

    Full Text Available The majority of clinical studies requires extensive management of human specimen including e.g. overnight shipping of blood samples in order to convey the samples in a central laboratory or to simultaneously analyze large numbers of patients. Storage of blood samples for periods of time before in vitro/ex vivo testing is known to influence the antigen expression on the surface of lymphocytes. In this context, the present results show for the first time that the T cell antigen CD3 can be substantially detected on the surface of human B cells after ex vivo storage and that the degree of this phenomenon critically depends on temperature and duration after blood withdrawal. The appearance of CD3 on the B cell surface seems to be a result of contact-dependent antigen exchange between T and B lymphocytes and is not attributed to endogenous production by B cells. Since cellular subsets are often classified by phenotypic analyses, our results indicate that ex vivo cellular classification in peripheral blood might result in misleading interpretations. Therefore, in order to obtain results reflecting the in vivo situation, it is suggested to minimize times of ex vivo blood storage after isolation of PBMC. Moreover, to enable reproducibility of results between different research groups and multicenter studies, we would emphasize the necessity to specify and standardize the storage conditions, which might be the basis of particular findings.

  3. Possible influence of the ENSO phenomenon on the pathoecology of diphyllobothriasis and anisakiasis in ancient Chinchorro populations

    Bernardo T Arriaza

    2010-02-01

    Full Text Available Current clinical data show a clear relationship between the zoonosis rates of Diphyllobothrium pacificum and Anisakis caused by the El Niño Southern Oscillations (ENSO phenomenon along the Chilean coast. These parasites are endemic to the region and have a specific habitat distribution. D. pacificum prefers the warmer waters in the northern coast, while Anisakis prefers the colder waters of Southern Chile. The ENSO phenomenon causes a drastic inversion in the seawater temperatures in this region, modifying both the cool nutrient-rich seawater and the local ecology. This causes a latitudinal shift in marine parasite distribution and prevalence, as well as drastic environmental changes. The abundance of human mummies and archaeological coastal sites in the Atacama Desert provides an excellent model to test the ENSO impact on antiquity. We review the clinical and archaeological literature debating to what extent these parasites affected the health of the Chinchorros, the earliest settlers of this region. We hypothesise the Chinchorro and their descendants were affected by this natural and cyclical ENSO phenomenon and should therefore present fluctuating rates of D. pacificum and Anisakis infestations.

  4. Studies on so-called redistribution phenomenon of cerebral blood flow imaging

    Oba, Hiroshi

    1989-01-01

    To elucidate the relationship between so-called redistribution phenomenon and metabolism or viability of the brain tissue, a new quantitative triple-radionuclide autoradiography was developed, whereby making it possible to compare both late images and reditribution of IMP with cerebral metabolism in experimentally induced unilateral ischemic brain tissue of rats. Iodine-123 IMP and I-125 IMP were used as tracers for early and late imaging, and H-3 amino acid mixture or H-3 H-2 deoxyglucose as a tracer for protein synthesis or glucose metabolism imaging. There was no significant relationship between redistribution index and protein synthesis or glucose metabolism. Protein synthesis was remarkably decreased in the affected hemisphere regardless of redistribution index values. Although the redistribution indices showed a gentle peak at approximately 34 μ mol/100 g/ min of glucose metabolism, there was no obvious relationship between either late images or redistribution index images and glucose metabolism images. Redistribution indices showed a maximum value at approximately 40 to 50 ml/100 g/min of cerebral blood flow. Reverse redistribution was observed with 160 ml/100 g/min or more of flow. Thin layer chromatographic findings were similar in the affected and non-affected resions, suggesting redistribution of a lipophilic IMP metabolite of p-iodoamphetamine in the affected region. In vitro autoradiography revealed no significant reduction in binding ability of IMP to the affected ischemic cortex. In a computer simulation study for brain activity curve, brain activity at 150 min was found to be almost constant at more than 25 ml/100 g/min of flow. IMP redistribution was unlikely to reflect directly either brain metabolism or function, and both blood flow partition coefficient and blood flow values were independently responsible for cerebral kinetics of IMP.

    The complex direct contact condensation phenomenon is investigated in horizontal flow channels both experimentally and numerically with special emphasis on its implications on safety assessment studies. Under certain conditions direct contact condensation can act as the driving force for the water hammer phenomenon with potentially local devastating results, thus posing a threat to the integrity of the affected NPP components. New experimental results of in-depth analysis of the direct contact condensation phenomena obtained in Kaunas at the Lithuanian Energy Institute will be presented. The German system code ATHLET employing for the calculation of the heat transfer coefficient a mechanistic model accounting for two different eddy length scales, combined with the interfacial area transport equation will be assessed against condensation induced water hammer experimental data from the integral thermal-hydraulic experimental facility PMK-2, located at the KFKI Atomic Energy Research Institute in Budapest Hungary.

  8. PHENOMENON OF TAX LOSSES OF STATE BUDGETARY RESOURCES

    Larysa Sidelnykova

    2015-11-01

    Full Text Available The aim of this work is structuring categorical-conceptual apparatus of the of the tax losses phenomenon in the state budgetary resources, namely clarification of the concepts of “tax gap”, “tax expenditures”, “tax losses”, as well as the quantification of tax losses of the Consolidated budget of Ukraine. Methodology. Most modern scholars interpret the tax gaps as the amount of taxes that were not received with the budget as a result of shadow economy, tax evasion and the existence of tax debt. However, considerable asymmetry of the tax component of the state budgetary resources also arises due to budget losses of all levels as a result of providing tax exemptions. In modern economic literature such losses are considered as tax expenditures. We consider tax losses a generalizing concept including potential amounts of tax revenues that the state and local budgets have not received as a result of the existence of the phenomenon of “tax gaps” and “tax expenditures”, and the amount of losses of the state budgetary resources in terms of their tax component is equal to the sum total of tax exemptions provided, unsettled tax debt of economic agents and the loss of tax revenue due to the operation of shadow economy. The study is based on the analysis of tax losses of budgetary resources of Ukraine during the period of time from 2004 to 2014. The results of the study showed enormous losses of budgetary resources in Ukraine due to the imperfection of the tax system, spread of undisclosed operations, tax evasion, and inefficient fiscal policy implementation. The Consolidated budget loses the amounts of monetary funds, equal to an average of 53.30% of actual revenue over the period studied. Total tax losses of the state budgetary resources in 2014 are equivalent to the total actual expenditures of the Consolidated budget of Ukraine on social protection and social security, defense, public order, security and judicial authorities.

    Meli, Madeleine; Gitzelmann, Gabriela; Koppensteiner, Renate; Amann-Vesti, Beatrice R

    2006-03-01

    The objective of this study was to evaluate the long-term follow-up of patients with Raynaud's phenomenon (RP) and pathological nailfold capillaroscopy (NC) in order to analyse the predictive value of specific features of capillaroscopy for the development of a connective tissue disease (CTD). From 1992 to 2002, NC alone or combined with fluorescence videomicroscopy with sodium fluorescein (NaF) was performed in 1024 consecutive patients because of RP. We analysed the follow-up and pathological features of NC in all patients who had neither clinical nor serological signs of a CTD at the time of NC. Of 308 patients with neither serological findings nor clinical signs of CTD but with RP and pathological features in NC suspicious for CTD, follow-up data were available for 133 patients. An additional NaF test had been performed in 51 (38.4%) patients. After a mean follow-up of 6.5 years (range: 1-15 years), 109 patients had developed a CTD and 24 patients did not show any clinical signs or serological markers for a CTD after a mean follow-up of 8.5 years (range: 2-15 years). There were no differences in age, duration of RP or of follow-up in patients who developed a CTD compared to patients who did not. Significantly more giant capillaries (p=0.0001), avascular fields (p=0.02) and irregular architecture (p=0.0001) had been observed in patients who had developed a CTD during the follow-up of 6.5 years. The presence of giant capillaries, avascular fields and irregular architecture of nailfold capillaries is predictive for the development of a CTD in patients with RP.

    Vernon LF

    2018-04-01

    Full Text Available Leonard F Vernon Sherman College of Chiropractic, Spartanburg, SC, USA Abstract: The standard definition of spontaneous regression (SR of cancer is as follows, “…when a malignant tumor partially or completely disappears without treatment or in the presence of therapy which is considered inadequate to exert a significant influence on neoplastic disease.” SR is also known as Saint Peregrine tumor, the name taken from a young priest, Peregrine Laziosi (1260 [5]–1345, exact date is unknown, who had been diagnosed with a tumor of the tibia. The mass eventually grew so large that it broke through the skin and became severely infected. The available treatment for this condition was limited to amputation. Historical records report that on the day of surgery, physicians found that the tumor had disappeared and reportedly never returned. To date, the medical literature consists only of individual case studies and overviews of this phenomenon. The most cited work on the subject was done by surgeons Tilden Everson and Warren Cole who reviewed 176 published cases of SR from 1900 to 1960. While a percentage of these were found not to be cases of SR, there remained a number of unexplained cases. A frequent theme in many cases of SR is the co-occurrence of infection. Given the current interest in immunotherapy in the treatment of cancer, this article discusses one of the very early pioneers of this theory, William Bradley Coley, MD, a surgeon who was clearly ahead of his time. Ostracized by colleagues for his belief that stimulation of the immune system could in fact produce a regression of cancer, Coley remained convinced that his theory was right and, while he was not familiar with cytokines such as tumor necrosis factor (TNF, interferons, and streptokinase, he knew instinctively that an innate immune response was taking place.

  11. Load and speed effects on the cervical flexion relaxation phenomenon

    Descarreaux Martin

    2010-03-01

    Full Text Available Abstract Background The flexion relaxation phenomenon (FRP represents a well-studied neuromuscular response that occurs in the lumbar and cervical spine. However, the cervical spine FRP has not been investigated extensively, and the speed of movement and loading effects remains to be characterized. The objectives of the present study were to evaluate the influence of load and speed on cervical FRP electromyographic (EMG and kinematic parameters and to assess the measurement of cervical FRP kinematic and EMG parameter repeatability. Methods Eighteen healthy adults (6 women and 12 men, aged 20 to 39 years, participated in this study. They undertook 2 sessions in which they had to perform a standardized cervical flexion/extension movement in 3 phases: complete cervical flexion; the static period in complete cervical flexion; and extension with return to the initial position. Two different rhythm conditions and 3 different loading conditions were applied to assess load and speed effects. Kinematic and EMG data were collected, and dependent variables included angles corresponding to the onset and cessation of myoelectric silence as well as the root mean square (RMS values of EMG signals. Repeatability was examined in the first session and between the 2 sessions. Results Statistical analyses revealed a significant load effect (P Conclusions The load increase evoked augmented FRP onset and cessation angles as well as heightened muscle activation. Such increments may reflect the need to enhance spinal stability under loading conditions. The kinematic and EMG parameters showed promising repeatability. Further studies are needed to assess kinematic and EMG differences between healthy subjects and patients with neck pain.

  12. Kasabach-Merritt phenomenon: a single centre experience.

    Ryan, Clodagh

    2012-01-31

    OBJECTIVE: Kasabach-Merritt phenomenon (KMP) can lead to life-threatening bleeding, and its optimum treatment has not been established. We review the experience of managing KMP in a single institution. METHODS: A retrospective chart review on all children with KMP treated at the Hospital for Sick Children, Toronto, over an 18 yr period was carried out. RESULTS: All 15 patients had profound thrombocytopenia and hypofibrinogenemia at presentation, half had bleeding symptoms, and three had cardiac failure. All patients received corticosteroids. Five responded to steroids alone, given for an average of 13 wk, increasing platelets to >20 x 10(9)\\/L at a mean of 6.2 d and fibrinogen >1 g\\/dL at 25.6 d. Ten patients received at least one other therapeutic modality in addition to steroids, including vincristine, interferon, anti-platelet agents and pentoxifylline. Five patients received vincristine, for a mean of 6 wk, with two patients responding. Eight patients received interferon, for a mean of 4 months, with two patients responding. Overall, the mean time to increasing platelets >20 x 10(9)\\/L was 56 d, to >150 x 10(9)\\/L was 88 d and fibrinogen >1 g\\/dL 49 d. Ten patients showed a partial response to embolisation, with a mean of 2.8 procedures performed. Thrombotic complications occurred in 7%. Twelve patients remain alive, with relapse in six patients, all treated successfully. One patient died, and two patients have been lost to follow-up. CONCLUSION: KMP is a rare condition, with significant morbidity and mortality. The therapeutic approach should include a multidisciplinary team and consensus on guidelines.

  13. Economy As A Phenomenon Of Culture: Theoretical And Methodological Analysis

    S. N. Ivaskovsky

    2017-01-01

    Full Text Available The article redefines economy as a phenomenon of culture, a product of a historically and socially grounded set of values shared by members of a given society. The research shows that culture is not always identical to social utility, because there are multiple examples when archaic, traditionalist, irrational cultural norms hinder social and economic progress and trap nations into poverty and underdevelopment. One of the reasons for the lack of scholarly attention to cultural dimension of economy is the triumph of positivism in economics. Mathematics has become the dominant language of economic analysis. It leads to the transformation of the economics into a sort of «social physics», accompanied by the loss of its original humanitarian nature shared in the works of all the great economists of the past. The author emphasizes the importance of the interdisciplinary approach to the economic research and the incorporation of the achievements of the other social disciplines – history, philosophy, sociology and cultural studies - into the subject matter of economic theory. Substantiating the main thesis of the article, the author shows that there is a profound ontological bond between economy and culture, which primarily consists in the fact that these spheres of human relations are aimed at the solution of the same problem – the competitive selection of the best ways for survival of people, of satisfying the relevant living needs. In order to overcome the difficulties related to the inclusion of culture in the set of analytical tools used in the economic theory, the author suggests using a category of «cultural capital», which reestablishes the earlier and more familiar for the economists meaning of capital.

  14. Current pathophysiological views on vibration-induced Raynaud's phenomenon.

    Stoyneva, Z; Lyapina, M; Tzvetkov, D; Vodenicharov, E

    2003-03-01

    This review attempts to summarize and discuss contemporary pathogenetic views on vibration-induced Raynaud's phenomenon assuming its multifactorial etiology. An increase in central and peripheral sympathetic nervous activity is discussed based on different physiological indicators of autonomic dysfunction and sympathetic hyperactivity. Local acral vasodysregulation is considered. Receptor and nerve endings dysfunction presented with predominance of alpha(2)-receptor function in the digital arteries and neuronal loss in those digital cutaneous perivascular nerves containing calcitonin gene-related peptide result in deficiency of endogenous release of this powerful vasodilator. Endothelial damage and dysregulation induced by vibration and increased shear stresses are demonstrated by the elevated plasma level of thrombomodulin and of von Willebrand factor and reduced endothelium-dependent vasodilator responses. The concentrations of endothelin-1 are high, the highest being in most advanced stages. Decreased plasma thiol level, indicating increased production and activity of free radicals, contribute to vasospastic paroxysms in vibration white finger patients. Dysbalance of local vasoactive factors with opposing effects on vascular smooth muscle like endothelin and nitric oxide, endothelin and calcitonin gene-related peptide, nitric oxide and superoxide anion are discussed. Disturbed smooth muscle response is supposed. Changes in hemostasis, fibrinolysis and hemorrheology, activation of blood cells with erythrocyte hyperaggregation and red cell hypodeformability, platelet aggregation with increased release of vasoconstricting thromboxane A(2) and serotonin as well as leukocyte activation, entrapment within capillaries and post-capillary venules and increased reactive oxygen species and lysosomal lytic enzymes release might also contribute to digital vasospasms and tissue damage. Elevated soluble intercellular adhesion molecule-1 levels involved in the adherence of

Many factors in the interesting interaction between genotype and phenotype (eg, high cardiorespiratory fitness, higher hemoglobin concentration, good metabolic efficiency, muscle fiber composition, enzyme profile, diet, altitude training, and psychological aspects have been proposed in the attempt to explain the extraordinary success of these runners. Increasing evidence shows that genetics may be a determining factor in physical and athletic performance. But, could this also be true for African long-distance runners? Based on this question, this brief review proposed the role of genetic factors (mitochondrial deoxyribonucleic acid, the Y chromosome, and the angiotensin-converting enzyme and the alpha-actinin-3 genes in the amazing athletic performance observed in African runners, especially the Kenyans and Ethiopians, despite their environmental constraints.Keywords: genes, genotype, physical exercise, endurance runners

    Full Text Available The subject of the research in this paper is the emergence of big data phenomenon and application of big data technologies for business' needs with the specific emphasis on marketing and trade. The purpose of the research is to make a comprehensive overview of different discussions about the characteristics, application possibilities, achievements, constraints and the future of big data development. Based on the relevant literature, the concept of big data is presented and the potential of large impact of big data on business activities is discussed. One of the key findings indicates that the most prominent change that big data brings to the business arena is the appearance of new business models, as well as revisions of the existing ones. Substantial part of the paper is devoted to the marketing and marketing research which are under the strong impact of big data. The most exciting outcomes of the research in this domain concerns the new abilities in profiling the customers. In addition to the vast amount of structured data which are used in marketing for a long period, big data initiatives suggest the inclusion of semi-structured and unstructured data, opening up the room for substantial improvements in customer profile analysis. Considering the usage of information communication technologies (ICT as a prerequisite for big data project success, the concept of Networked Readiness Index (NRI is presented and the position of Serbia and regional countries in NRI framework is analyzed. The main outcome of the analysis points out that Serbia, with its NRI score took the lowest position in the region, excluding Albania. Also, Serbia is lagging behind the appropriate EU mean values regarding all observed composite indicators - pillars. Further on, this analysis reveals the domains of ICT usage in Serbia, which could be focused for an improvement and where incentives can be made.

    Konstantinov, Pavel; Akhmetova, Alina

    2015-04-01

    Urban Heat Island (UHI) phenomenon is well known in scientific literature since first half of the 19th century [1]. By now a wide number of world capitals is described from climatological point of view, especially in mid-latitudes. In beginning of XXI century new studies focus on heat island of tropical cities. However dynamics UHI in extreme continental climates is insufficiently investigated, due to the fact that there isn't large cities in Europe and Northern America within that climate type. In this paper we investigate seasonal and diurnal dynamics UHI intensity for Astana, capital city of Kazakhstan (population larger than 835 000 within the city) including UHI intensity changes on different time scales. Now (since 1998) Astana is the second coldest capital city in the world after Ulaanbaatar, Mongolia [3] For this study we use the UHI investigation technology, described in [2]. According to this paper, we selected three stations: one located into city in high and midrise buildings area (including extensive lowrise and high-energy industrial - LCZ classification) and two others located in rural site (sparsely built or open-set and lightweight lowrise according LCZ classification). Also these stations must be close by distance (less than 100 km) and altitude. Therefore, first for Astana city were obtained numerical evaluations for UHI climate dynamics, UHI dependence of synoptic situations and total UHI climatology on monthly and daily averages.

    Full Text Available Globalization represents a controversial phenomenon both because of its complexity and because of the various implications it has on the global economy. Globalization will act simultaneously on many levels, its effects being correlated with the diversity of the angles from which this phenomenon can be approached from – economic, social, politic, cultural, philosophic etc. The article represents an incursion into the issue regarding the implications and effects of globalization grouped in several areas of analysis such as the disappearance of borders, the effects on culture, the effects on the education, the impact on labour market impact and the phenomenon of immigration, the effects of globalization in the context of the food crisis underdevelopment and poverty. To complete the analysis that points out enough elements considered to be negative, at the end of the article, there are also approached the development opportunities that globalization can offer in terms of boosting the economic exchanges, the exchange of genuine cultural values and ensuring a transfer of information at a global scale, so necessary for the scientific and technological progress.  The conclusions of the article weighs the many aspects highlighted, both negative and positive, and suggests a series of useful research directions in order to fathom the complex features of this concept so controversial – globalization.
