    Recently, studies using a social ecological perspective have identified important micro- and macro-level risk factors for excessive adiposity in youth. Although considerable research exists examining these relationships, few studies have applied a socioecological approach to simultaneously examine both micro- and macro-level factors in young children while objectively assessing adiposity via dual-energy x-ray absorptiometry (DXA). To examine race and sex differences in adiposity measured by DXA in a large sample of young children and to identify both micro- and macro-level correlates of adiposity. Cross-sectional. Elementary school children (N = 495) from the southeastern United States participated. Anthropometrics, percentage body fat via DXA, and psychosocial variables via questionnaire were assessed in the Fall of 2003. Community-level sociodemographic data and built-environment variables via geographic information system were collected in Spring 2009. Data analyses were completed in the Spring of 2010. Percentage body fat in white children was higher than in nonwhite children. Higher percentage body fat and poorer cardiovascular fitness were found in females compared with males. Percentage body fat was higher in children who had lower athletic competence and lived in neighborhoods with higher percentages of minority residents. This study provides preliminary support for the social-ecological model to explain variance in adiposity in children. Developers of health promotion programs for children living in minority neighborhoods should consider factors at multiple levels of the ecological model when designing and implementing programs.

    Full Text Available This paper presents a macro-level model of a solid oxide fuel cell (SOFC stack implemented in Aspen Plus® for the simulation of SOFC system. The model is 0-dimensional and accepts hydrocarbon fuels such as reformed natural gas, with user inputs of current density, fuel and air composition, flow rates, temperature, pressure, and fuel utilization factor. The model outputs the composition of the exhaust, work produced, heat available for the fuel reformer, and electrochemical properties of SOFC for model validation. It was developed considering the activation, concentration, and ohmic losses to be the main over-potentials within the SOFC, and mathematical expressions for these were chosen based on available studies in the literature. The model also considered the water shift reaction of CO and the methane reforming reaction. The model results were validated using experimental data from Siemens Westinghouse. The results showed that the model could capture the operating pressure and temperature dependency of the SOFC performance successfully in an operating range of 1–15 atm for pressure and 900 °C–1,000 °C for temperature. Furthermore, a sensitivity analysis was performed to identify the model constants and input parameters that impacted the over-potentials.

    Macro-level legal and ethical issues play a significant role in the successful translation of knowledge into practice. The medicolegal milieu, in particular, can promote clinical inertia and stifle innovation. Embracing new clinical practice guidelines and best practice models has not protected physicians from superfluous torts; in some cases, emerging evidence has been used as the dagger of trial lawyers rather than the scalpel of physicians. Beyond the legal challenges are overarching justice issues that frame the broad goals of knowledge translation (KT) and technology diffusion. Optimal implementation of the latest evidence requires attention to be paid to the context of the candidate community and the key opinion leaders therein, characterized by the "8Ps" (public, patients, press, physicians, policy makers, private sector, payers, and public health). Ethical and equitable KT also accounts for the global burdens and benefits of implementing innovation such that disparities and gaps in health experienced by the least advantaged are prioritized. Researchers and thought leaders must attend to questions of fairness, economics, and legal risk when investigating ways to promote equity-oriented KT.

  4. Vividness of visual imagery and incidental recall of verbal cues, when phenomenological availability reflects long-term memory accessibility

    Full Text Available The relationship between vivid visual mental images and unexpected recall (incidental recall was replicated, refined and extended. In Experiment 1, participants were asked to generate mental images from imagery-evoking verbal-cues (controlled on several verbal properties and then, on a trial-by-trial basis, rate the vividness of their images; thirty minutes later, participants were surprised with a task requiring free recall of the cues. Higher vividness ratings predicted better incidental recall of the cues than individual differences (whose effect was modest. Distributional analysis of image latencies through ex-Gaussian modeling showed an inverse relation between vividness and latency. However, recall was unrelated to image latency. The follow-up Experiment 2 showed that the processes underlying trial-by-trial vividness ratings are unrelated to the Vividness of Visual Imagery Questionnaire (VVIQ, as further supported by a meta-analysis of a randomly selected sample of relevant literature. The present findings suggest that vividness may act as an index of availability of long-term sensory traces, playing a non-epiphenomenal role in facilitating the access of those memories.

    Research that links macro-level socioeconomic development variables to health care human resources workforce composition is scarce at best. The purpose of this study was to explore the links between nonnursing factors and nursing workforce composition through a secondary, descriptive analysis of year 2000, publicly available national nursing human resources data from Mexico. Building on previous research, the authors conducted multiple robust regression analysis by federal typing of nursing human resources from 31 Mexican states against macro-level socioeconomic development variables. Average education in a state was significantly associated in predicting all types of formally educated nurses in Mexico. Other results suggest that macro-level indicators have a different association with each type of nurse. Context may play a greater role in determining nursing workforce composition than previously thought. Further studies may help to explain differences both within and between countries.

    Although the effect of time to death (TTD) on health care expenditures (HCE) has been investigated using individual level data, the most profound implications of TTD have been for the forecasting of macro-level HCE. Here we estimate the TTD model using macro-level data from the Netherlands consisting of mortality rates and age- and gender-specific per capita health expenditures for the years 1981-2007. Forecasts for the years 2008-2020 of this macro-level TTD model were compared to forecasts that excluded TTD. Results revealed that the effect of TTD on HCE in our macro model was similar to those found in micro-econometric studies. As the inclusion of TTD pushed growth rate estimates from unidentified causes upwards, however, the two models' forecasts of HCE for the 2008-2020 were similar. We argue that including TTD, if modeled correctly, does not lower forecasts of HCE.

    A recurrent finding in international literature is a greater prevalence of depression in women than in men. While explanations for this gender gap have been studied extensively at the individual level, few researchers have studied macro-level determinants of depression in men and women. In the current study we aim to examine the micro-macro linkage of the relationship between gender equality and depression by gender in Europe, using data from the European Social Survey, 2006-2007 (N=39,891). Using a multilevel framework we find that a high degree of macro-level gender equality is related to lower levels of depression in both women and men. It is also related to a smaller gender difference in depression, but only for certain social subgroups and only for specific dimensions of gender equality. © 2013 The Authors.

    In this monograph we consider the development of Web Science since the launch of this journal and its inaugural publication ‘A Framework for Web Science’. The theme of emergence is discussed as the characteristic phenomenon of Web-scale applications, where many unrelated micro-level actions and decisions, uninformed by knowledge about the macro-level, still produce noticeable and coherent effects at the scale of the Web. A model of emergence is mapped onto the multitheoretical multilevel (MTM...

  10. Changes in Income at Macro Level Predict Sex Ratio at Birth in OECD Countries.

    Kanninen, Ohto; Karhula, Aleksi

    2016-01-01

    The human sex ratio at birth (SRB) is approximately 107 boys for every 100 girls. SRB was rising until the World War II and has been declining slightly after the 1950s in several industrial countries. Recent studies have shown that SRB varies according to exposure to disasters and socioeconomic conditions. However, it remains unknown whether changes in SRB can be explained by observable macro-level socioeconomic variables across multiple years and countries. Here we show that changes in disposable income at the macro level positively predict SRB in OECD countries. A one standard deviation increase in the change of disposable income is associated with an increase of 1.03 male births per 1000 female births. The relationship is possibly nonlinear and driven by extreme changes. The association varies from country to country being particular strong in Estonia. This is the first evidence to show that economic and social conditions are connected to SRB across countries at the macro level. This calls for further research on the effects of societal conditions on general characteristics at birth.

  11. Assessment of Macro-Level Socioeconomic Factors That Impact Waterborne Diseases: The Case of Jordan

    Full Text Available The Hashemite Kingdom of Jordan is an example of a country that suffers from high water scarcity. Additionally, due to the economic drivers in the country, such as phosphate and potash extraction and pharmaceutical production, the little fresh water that remains is generally polluted. The infrastructure, often antiquated in urban areas and non-existent in rural areas, also contributes to poor water conditions and to the spread of waterborne diseases. This paper examines the socioeconomic factors that contribute to diarrhea and hepatitis A on a macro level in Jordan and discusses the public-policies that government officials could use to abate those problems. Ordinary least squares time series models are used to understand the macro-level variables that impact the incidence of these diseases in Jordan. Public health expenditure has a significant impact on reducing their incidence. Furthermore, investment in sanitation facilities in rural regions is likely to reduce the number of cases of hepatitis A. Perhaps the most surprising outcome is that importation of goods and services likely results in a decrease in cases of hepatitis A. However, income has little impact on the incidence of diarrhea and hepatitis A.

    Background: Hurricane Sandy caused extensive physical and economic damage but the long-term health impacts are unknown. Flooding is a central component of hurricane exposure, influencing health through multiple pathways that unfold over months after flooding recedes. This study assesses concordance in Federal Emergency Management (FEMA) and self-reported flood exposure after Hurricane Sandy to elucidate discrepancies in flood exposure assessments. Methods: Three meter resolution New York State flood data was obtained from the FEMA Modeling Task Force Hurricane Sandy Impact Analysis. FEMA data was compared to self-reported flood data obtained through validated questionnaires from New York City and Long Island residents following Sandy. Flooding was defined as both dichotomous and continuous variables and analyses were performed in SAS v9.4 and ArcGIS 10.3.1. Results: There was a moderate agreement between FEMA and self-reported flooding (Kappa statistic 0.46) and continuous (Spearman's correlation coefficient 0.50) measures of flood exposure. Flooding was self-reported and recorded by FEMA in 23.6% of cases, while agreement between the two measures on no flooding was 51.1%. Flooding was self-reported but not recorded by FEMA in 8.5% of cases, while flooding was not self-reported but indicated by FEMA in 16.8% of cases. In this last instance, 84% of people (173/207; 83.6%) resided in an apartment (no flooding reported). Spatially, the most concordance resided in the interior of New York City / Long Island, while the greatest areas of discordance were concentrated in the Rockaway Peninsula and Long Beach, especially among those living in apartments. Conclusions: There were significant discrepancies between FEMA and self-reported flood data. While macro-level FEMA flood data is a relatively less expensive and faster way to provide exposure estimates spanning larger geographic areas affected by Hurricane Sandy than micro-level estimates from cohort studies, macro-level

    Full Text Available The objective of this research is to identify the common direct and indirect (micro and macro level dispute causes in residential building projects in Saudi Arabia. The questionnaire method was used in this research. Randomly distributed questionnaire technique was applied to 120 contractors to evaluate the severity of the identified 29 direct dispute causes and 32 indirect dispute causes. The analysis of the identified causes indicates that the top five severe direct dispute causes are: delay in progress payment by owner, unrealistic contract duration, change orders, poor quality of completed works, and labor inefficiencies respectively. While the top five severe indirect dispute causes are: inadequate contractor’s experience, lack of communication between construction parties, ineffective planning and scheduling of project by contractor, cash problems during construction, and poor estimation practices.

    Full Text Available The aim of this study is to compare country output and citation impact as well as to assess the level of interdisciplinarity in the field of tribology research during the period 1998-2012, based on the SCOPUS database. Macro-level scientometric indicators such as growth rate, share of international collaborative papers, citation per paper, share of un-cited papers, and publication efficiency index were employed. Further, the Simpson Index of Diversity was used to measure the level of interdisciplinarity. The performance of top countries contributing more than 1000 papers during the study period was discussed. Contributions and share of continents and countries by income groups were examined. Further research contributions and citation impact of selected country groups were analyzed. This study reveals that high levels of interdisciplinarity exist in tribology research. Asia outperforms the other world regions and China contributes most of the papers (25%, while the United States receives most of the citations (22%.

  17. Anthropogenic influences on macro-level mammal occupancy in the Appalachian Trail corridor.

    Peter L Erb

    Full Text Available Anthropogenic effects on wildlife are typically assessed at the local level, but it is often difficult to extrapolate to larger spatial extents. Macro-level occupancy studies are one way to assess impacts of multiple disturbance factors that might vary over different geographic extents. Here we assess anthropogenic effects on occupancy and distribution for several mammal species within the Appalachian Trail (AT, a forest corridor that extends across a broad section of the eastern United States. Utilizing camera traps and a large volunteer network of citizen scientists, we were able to sample 447 sites along a 1024 km section of the AT to assess the effects of available habitat, hunting, recreation, and roads on eight mammal species. Occupancy modeling revealed the importance of available forest to all species except opossums (Didelphis virginiana and coyotes (Canis latrans. Hunting on adjoining lands was the second strongest predictor of occupancy for three mammal species, negatively influencing black bears (Ursus americanus and bobcats (Lynx rufus, while positively influencing raccoons (Procyon lotor. Modeling also indicated an avoidance of high trail use areas by bears and proclivity towards high use areas by red fox (Vulpes vulpes. Roads had the lowest predictive power on species occupancy within the corridor and were only significant for deer. The occupancy models stress the importance of compounding direct and indirect anthropogenic influences operating at the regional level. Scientists and managers should consider these human impacts and their potential combined influence on wildlife persistence when assessing optimal habitat or considering management actions.

  18. Macro-level modeling of the response of C. elegans reproduction to chronic heat stress.

    2012-01-01

    Full Text Available A major goal of systems biology is to understand how organism-level behavior arises from a myriad of molecular interactions. Often this involves complex sets of rules describing interactions among a large number of components. As an alternative, we have developed a simple, macro-level model to describe how chronic temperature stress affects reproduction in C. elegans. Our approach uses fundamental engineering principles, together with a limited set of experimentally derived facts, and provides quantitatively accurate predictions of performance under a range of physiologically relevant conditions. We generated detailed time-resolved experimental data to evaluate the ability of our model to describe the dynamics of C. elegans reproduction. We find considerable heterogeneity in responses of individual animals to heat stress, which can be understood as modulation of a few processes and may represent a strategy for coping with the ever-changing environment. Our experimental results and model provide quantitative insight into the breakdown of a robust biological system under stress and suggest, surprisingly, that the behavior of complex biological systems may be determined by a small number of key components.

    2008-01-01

    Preparedness for a possible global pandemic caused by viruses such as the highly pathogenic influenza A subtype H5N1 has become a global priority. In particular, it is critical to monitor the appearance of any new emerging subtypes. Comparative phyloinformatics can be used to monitor, analyze, and possibly predict the evolution of viruses. However, in order to utilize the full functionality of available analysis packages for large-scale phyloinformatics studies, a team of computer scientists, biostatisticians and virologists is needed--a requirement which cannot be fulfilled in many cases. Furthermore, the time complexities of many algorithms involved leads to prohibitive runtimes on sequential computer platforms. This has so far hindered the use of comparative phyloinformatics as a commonly applied tool in this area. In this paper the graphical-oriented workflow design system called Quascade and its efficient usage for comparative phyloinformatics are presented. In particular, we focus on how this task can be effectively performed in a distributed computing environment. As a proof of concept, the designed workflows are used for the phylogenetic analysis of neuraminidase of H5N1 isolates (micro level) and influenza viruses (macro level). The results of this paper are hence twofold. Firstly, this paper demonstrates the usefulness of a graphical user interface system to design and execute complex distributed workflows for large-scale phyloinformatics studies of virus genes. Secondly, the analysis of neuraminidase on different levels of complexity provides valuable insights of this virus's tendency for geographical based clustering in the phylogenetic tree and also shows the importance of glycan sites in its molecular evolution. The current study demonstrates the efficiency and utility of workflow systems providing a biologist friendly approach to complex biological dataset analysis using high performance computing. In particular, the utility of the platform Quascade

  5. What can alcohol researchers learn from research about the relationship between macro-level gender equality and violence against women?

    Roberts, Sarah C M

    2011-01-01

    This systematic review focuses on research about macro-level gender equality and violence against women (VAW) and identifies conceptually and theoretically driven hypotheses as well as lessons relevant for alcohol research. Hypotheses include: amelioration--increased equality decreases VAW; backlash--increased equality increases VAW; and convergence--increased equality reduces the gender gap; and hypotheses that distinguish between relative and absolute status, with relative status comparing men's and women's status and absolute status measuring women's status without regard to men. Systematic review of studies published through June 2009 identified through PubMed and Web of Science, as well as citing and cited articles. A total of 30 studies are included. Of 85 findings examining amelioration/backlash, 25% support amelioration, 22% backlash; and 53% are null. Of 13 findings examining convergence, 31% support and 23% are inconsistent with convergence; 46% are null. Neither the existence nor the direction of the equality and VAW relationship can be assumed. This suggests that the relationship between macro-level gender equality and alcohol should also not be assumed, but rather investigated through research.

    Carretero, Stephanie; Stewart, James; Centeno, Clara

    The aim of this study was to explore the benefits of information and communication technologies (ICT)-based services for informal carers and paid assistants of older people living in the community. We cross-case analysed the effects of twelve initiatives in the EU, the USA and Canada, based on their individual analysis documented through interviews with promoters and a literature review. We carried out the cross-case analysis following a variables-oriented strategy on seven dimensions of impact at micro-, meso- and macro-levels: the quality of life of informal carers and paid assistants, quality of life of care recipients, quality of care, care efficiency and sustainability, acceptability, and infrastructure and accessibility. ICT-based services for informal carers and paid assistants improve the quality of life of older people and their carers and access to qualified care. They also generate savings which contribute to the sustainability of the care systems. These findings constitute a first look at the benefits of the use of ICT-based services for informal carers and paid assistants. Nevertheless, more research using experimental methods is needed to demonstrate the impact of these ICT-based services at meso- and macro-levels. This would help to support policy-makers to deploy these technologies for long-term care delivery.

  7. Using a micro-level model to generate a macro-level model of productive successful aging.

    Johnson, Jessica K M; Sarkisian, Natalia; Williamson, John B

    2015-02-01

    Aging successfully entails good physical and cognitive health, as well as ongoing participation in social and productive activity. This study hones in on participation in productive activity, a factor that makes an important contribution to successful aging. One conceptual model of productive activity in later life specifies the antecedents and consequences of productivity. This study draws on that micro-level model to develop a corresponding macro-level model and assesses its utility for examining the predictors of and explaining the relationships between one form of productivity (labor force participation rates) and one aspect of well-being (average life expectancy) among males and females. Random effects regression models and path analysis were used to analyze cross-national longitudinal data for 24 high-income Organization for Economic Co-operation and Development (OECD) countries at seven time points (1980-2010; 168 observations total). OECD countries with higher labor force participation rates among older workers have higher life expectancies. Labor force participation mediates the effects of gross domestic product per capita on male and female life expectancy, and it mediates the effect of self-employment rate for men, but it acts as a suppressor with regard to the effect of public spending on male and female life expectancy. A well-known micro-level model of productive activity can be fruitfully adapted to account for macro-level cross-national variation in productivity and well-being. © The Author 2014.

    BACKGROUND: This article describes trends and stability over time in health complaints in adolescents from 2002 to 2010 and investigates associations between health complaints, behavioural and social contextual factors at individual level and economic factors at macro-level. METHODS: Comprising N...... at macro-level (e.g. GDP, Gini), as can be seen by the small effect sizes (less than 5% for different trends). Health complaints are fairly stable over time in most countries, and no clear international trend in health complaints can be observed between 2002 and 2010. The most prominent stable determinants...... were being female, being bullied, school pressure and smoking. CONCLUSION: Factors associated with health complaints are more related to the proximal environment than to distal macro-level factors. This points towards intensifying targeted interventions, (e.g. for bullying) and also targeting specific...

    Full Text Available The study search the Rorschach point of view phenomenologycal. The phenomenology explore the psychopathological Erlebnis of subject. Psychic phenomena have the form and content. The phenomenological approach to Rorschach projective technique  begins with the assessment of psychogram, which explores the subject’s cognitive, affective and adaptive processes and then the object of psychopathology. In psychogram that expresses an aspect of the way of life inkblots by the person defining the location, the determinant, the presence of particular phenomena, the content  in relation to the answers of the Protocol. This approach establish structure, levels of psychic functioning of the subject and consent to make a  differential diagnosis.

    Quantum Chromodynamics is the most successful theory in particle physics. The understanding of all different signals at hadron colliders have been achieved due to the correct interpretation of the theory. In this paper we review some basic features of the theory of strong interactions and how it could be used in order to provide phenomenological distributions for the Large Hadron Collider. The main results presented in here can be found in Ref [1].

    Purpose To examine the relationship between country-level age norms for sexual initiation timing and early sexual initiation (ESI) among adolescent boys and girls. Methods Nationally-representative data from 17 countries that participated in the 2006/07 European Social Survey (ESS-3, n=33,092) and the 2005/06 Health Behaviour in School-Aged Children Study (HBSC, n=27,702) were analyzed. Age norms were measured as the average country-level response to an item asking the age at which ESS respondents believed someone is too young to have sexual intercourse. HBSC respondents (aged 14-16) self-reported age at sexual initiation which we defined as early (<15 years) or not (≥15 years or no initiation). Control variables included age, family affluence, perceived socioeconomic status, family living arrangement, substance use, school attachment, and country-level legal age of consent. Multivariable three-level logistic models with random intercepts were run separately by sex. Results In multivariable analyses, higher overall age norms were associated with reduced likelihood of ESI among girls (AOR 0.60, 95% CI 0.45-0.79); associations with ESI were stronger for parent cohort (ages 31-65) norms (AOR 0.37, 95% CI 0.23-0.58) than for peer cohort (ages 15-20) norms (AOR 0.60, 95% CI 0.49-0.74). For boys, overall norms were also significantly negatively associated with ESI (AOR 0.68, 95% CI 0.46-0.99), as were parent cohort norms (AOR 0.66, 95% CI 0.45-0.96). Peer cohort norms were not significantly related to boys’ ESI. Conclusion Macro-level cultural norms may impact adolescents’ sexual initiation timing. Research exploring the sexual health outcomes of early initiators in countries with contrasting age norms is warranted. PMID:24508092

  15. Polarizing cues.

    2012-01-01

    People categorize themselves and others, creating ingroup and outgroup distinctions. In American politics, parties constitute the in- and outgroups, and party leaders hold sway in articulating party positions. A party leader's endorsement of a policy can be persuasive, inducing co-partisans to take the same position. In contrast, a party leader's endorsement may polarize opinion, inducing out-party identifiers to take a contrary position. Using survey experiments from the 2008 presidential election, I examine whether in- and out-party candidate cues—John McCain and Barack Obama—affected partisan opinion. The results indicate that in-party leader cues do not persuade but that out-party leader cues polarize. This finding holds in an experiment featuring President Bush in which his endorsement did not persuade Republicans but it polarized Democrats. Lastly, I compare the effect of party leader cues to party label cues. The results suggest that politicians, not parties, function as polarizing cues.

  16. An empirical tool to evaluate the safety of cyclists: Community based, macro-level collision prediction models using negative binomial regression.

    2013-12-01

    Today, North American governments are more willing to consider compact neighborhoods with increased use of sustainable transportation modes. Bicycling, one of the most effective modes for short trips with distances less than 5km is being encouraged. However, as vulnerable road users (VRUs), cyclists are more likely to be injured when involved in collisions. In order to create a safe road environment for them, evaluating cyclists' road safety at a macro level in a proactive way is necessary. In this paper, different generalized linear regression methods for collision prediction model (CPM) development are reviewed and previous studies on micro-level and macro-level bicycle-related CPMs are summarized. On the basis of insights gained in the exploration stage, this paper also reports on efforts to develop negative binomial models for bicycle-auto collisions at a community-based, macro-level. Data came from the Central Okanagan Regional District (CORD), of British Columbia, Canada. The model results revealed two types of statistical associations between collisions and each explanatory variable: (1) An increase in bicycle-auto collisions is associated with an increase in total lane kilometers (TLKM), bicycle lane kilometers (BLKM), bus stops (BS), traffic signals (SIG), intersection density (INTD), and arterial-local intersection percentage (IALP). (2) A decrease in bicycle collisions was found to be associated with an increase in the number of drive commuters (DRIVE), and in the percentage of drive commuters (DRP). These results support our hypothesis that in North America, with its current low levels of bicycle use (macro-level CPMs. Copyright © 2012. Published by Elsevier Ltd.

  17. How do macro-level contexts and policies affect the employment chances of chronically ill and disabled people? Part I: The impact of recession and deindustrialization.

    Low employment rates of chronically ill and disabled people are of serious concern. Being out of work increases the risk of poverty and social exclusion, which may further damage the health of these groups, exacerbating health inequalities. Macro-level policies have a potentially tremendous impact on their employment chances, and these influences urgently need to be understood as the current economic crisis intensifies. In Part I of this two-part study, the authors examine employment trends for people who report a chronic illness or disability, by gender and educational level, in Canada, Denmark, Norway, Sweden, and the United Kingdom in the context of economic booms and busts and deindustrialization. People with the double burden of chronic illness and low education have become increasingly marginalized from the labor market. Deindustrialization may have played a part in this process. In addition, periods of high unemployment have sparked a downward trend in employment for already marginalized groups who did not feel the benefits when the economy improved. Norway and Sweden have been better able to protect the employment of these groups than the United Kingdom and Canada. These contextual differences suggest that other macro-level factors, such as active and passive labor market polices, may be important, as examined in part II.

    There is a great overlap between the way of seeing the world in clinical homeopathy and in the technical philosophical system known as phenomenology. A knowledge of phenomenologic principles reveals Hahnemann to have been an unwitting phenomenologist. The ideas of phenomenology as applied to medicine show that homeopathy is the ideal medical system to fulfill the goals of coming ever closer to true patient concerns and experience of illness.

  6. Development and application of dynamic hybrid multi-region inventory analysis for macro-level environmental policy analysis: a case study on climate policy in Taiwan.

    2013-03-19

    We develop a novel inventory method called Dynamic Hybrid Multi-Region Inventory analysis (DHMRI), which integrates the EEMRIOA and Integrated Hybrid LCA and applies time-dependent environmental intervention information for inventory analysis. Consequently, DHMRI is able to quantify the change in the environmental footprint caused by a specific policy while taking structural changes and technological dynamics into consideration. DHMRI is applied to assess the change in the total CO2 emissions associated with the total final demand caused by the climate policy in Taiwan to demonstrate the practicality of this novel method. The evaluation reveals that the implementation of mitigation measures included in the existing climate policy, such as an enhancement in energy efficiency, promotion of renewable energy, and limitation of the growth of energy-intensive industries, will lead to a 28% increase in the total CO2 emissions and that the main driver is the export-oriented electronics industry. Moreover, a major increase in the total emissions is predicted to occur in Southeast Asia and China. The observations from the case study reveal that DHMRI is capable of overcoming the limitations of existing assessment tools at macro-level evaluation of environmental policies.

  7. Neighborhood Crime and Perception of Safety as Predictors of Victimization and Offending Among Youth: A Call for Macro-Level Prevention and Intervention Models.

    2012-09-01

    This paper is one of two in a series that reports detailed findings from a larger study that simultaneously explored individual, family and neighborhood level predictors of victimization and offending among youth. The current analysis aims to identify which neighborhood level factors have better predictive power with regard to type of victimization (direct and vicarious measures) and total offending overtime (Wave 1 and Wave 2). METHODS: Path analysis was conducted using data from a multi-wave, panel study (N=625) of youth ages 16-19 at Wave 1. A best fitting model was determined showing causal pathways from neighborhood level factors including crime and perception of safety, to direct and vicarious victimization through exposure to violence, and subsequent offending. FINDINGS: Neighborhood crime significantly predicted property victimization. Neighborhood crime and perception of safety significantly predicted vicarious victimization by exposure to violence in the neighborhood. Neighborhood crime and perception of safety were significantly associated with Wave 1 offending. Findings highlight the need for professionals who work with youth to be cognizant of how their environments influence their lives. Prevention and intervention models seeking to create sustainable change among youth should consider mezzo and macro level components that build and strengthen neighborhood capacity through community partnerships.

  10. "Phenomenology" and qualitative research methods.

    Science.gov (United States)

    Nakayama, Y

    1994-01-01

    Phenomenology is generally based on phenomenological tradition from Husserl to Heidegger and Merleau-Ponty. As philosophical stances provide the assumptions in research methods, different philosophical stances produce different methods. However, the term "phenomenology" is used in various ways without the definition being given, such as phenomenological approach, phenomenological method, phenomenological research, etc. The term "phenomenology" is sometimes used as a paradigm and it is sometimes even viewed as synonymous with qualitative methods. As a result, the term "phenomenology" leads to conceptual confusions in qualitative research methods. The purpose of this paper is to examine the term "phenomenology" and explore philosophical assumptions, and discuss the relationship between philosophical stance and phenomenology as a qualitative research method in nursing.

I describe the space of possible brain states, the space of possible conscious states, and a "supervenience function" linking them. I show how this framework can be used to associate phenomenological structures with neuro-computational structures, and vice-versa. I pay special attention to the relationship between (1) the relatively fast dynamics of consciousness and neural activity, and (2) the slower dynamics of knowledge update and brain development.

    1995-01-01

    We consider the low energy phenomenology of superstrings. In particular we analyse supersymmetry breaking via gaugino condensate and we compare the phenomenology of the two different approaches to stabilize the dilaton field. We study the cosmological constant problem and we show that it is possible to have supersymmetry broken and zero cosmological constant. Finally, we discuss the possibility of having an inflationary potential. Requiring that the potential does not destabilize the dilaton field imposes an upper limit to the density fluctuations which can be consistent with the COBE data.

    We argue that, in many situations, fits to elastic scattering data that were historically, and frequently still are, considered ''good'', are not justifiably so describable. Information about the dynamics of nucleon-nucleus and nucleus-nucleus scattering is lost when elastic scattering phenomenology is insufficiently ambitious. It is argued that in many situations, an alternative approach is appropriate for the phenomenology of nuclear elastic scattering of nucleons and other light nuclei. The approach affords an appropriate means of evaluating folding models, one that fully exploits available empirical data. It is particularly applicable for nucleons and other light ions. (orig.)

  16. Husserl, phenomenology and nursing.

    Science.gov (United States)

    Paley, J

    1997-07-01

    Discussions of phenomenological research in nursing consistently appeal to either Husserl or Heidegger in justifying the technical and conceptual resources they deploy. This paper focuses on Husserl, and examines the relationship between his phenomenology and the accounts of it that are to be found in the nursing literature. Three central ideas are given particular attention: the phenomenological reduction, phenomena, and essence. It is argued that nurse researchers largely misunderstand these concepts and that, as a result, their version of Husserl's philosophy bears little resemblance to the original. A further consequence is that the project of identifying the 'essential structure' of a phenomenon, typically adopted by the nurse researchers who cite Husserl as an authority, comes close to being unintelligible. It is suggested that, while the methods used in 'phenomenological' nursing research may still have some legitimacy, they cannot achieve what they are alleged to achieve, and they should be detached from the framework of Husserlian ideas and terminology which is supposed to justify them.

    The rapid increase in suicide rates in South Korea, particularly in the aftermath of the Asian economic crisis in the late 1990s, compares with the declining suicide rates observed in most other OECD countries over the same period. This study aimed to examine an array of macro-level societal factors that might have contributed to the rising suicide trend in South Korea. We first investigated whether this trend was unique to South Korea, or ubiquitous across five Asian countries/areas that are geographically and culturally similar (South Korea, Hong Kong, Japan, Singapore, and Taiwan), using WHO mortality data and national statistics (1980-2009). Age-standardised suicide rates (per 100,000 population) were calculated for each gender and age group (15-24, 25-44, 45-64, and 65+) for each country. Both panel data and country-specific time-series analyses were employed to investigate the impact of economic change and social integration/regulation on suicide. Despite similarities in geography and culture, the rising trend of suicide rates was unique to South Korea. This atypical trend was most apparent for people aged 65 and over, which was in sharp contrast to the decreasing suicide trends observed in the other four Asian countries. The results of the panel data analyses generally pointed to a negative relationship between economic growth and suicide rates, particularly for working-aged people. The results of the time-series analyses further suggested that low levels of social integration, as indicated by rising divorce rates, may also have a role in rising suicide rates in South Korea, particularly for older people. Furthermore, the association between suicide rates and economic adversity (unemployment and economic downturn) was most salient among middle-aged men in South Korea. Compared to four other East Asian countries/areas (Hong Kong, Japan, Singapore, and Taiwan), South Korea has uniquely experienced a rising trend of suicide rates over the past three decades

  3. Cue-Reactive Altered State of Consciousness Mediates the Relationship Between Problem-Gambling Severity and Cue-Reactive Urge in Poker-Machine Gamblers.

    2016-06-01

    In order to enhance our understanding of the nature of poker-machine problem-gambling, a community sample of 37 poker-machine gamblers (M age = 32 years, M PGSI = 5; PGSI = Problem Gambling Severity Index) were assessed for urge to gamble (responses on a visual analogue scale) and altered state of consciousness (assessed by the Altered State of Awareness dimension of the Phenomenology of Consciousness Inventory) at baseline, after a neutral cue, and after a gambling cue. It was found that (a) problem-gambling severity (PGSI score) predicted increase in urge (from neutral cue to gambling cue, controlling for baseline; sr (2) = .19, p = .006) and increase in altered state of consciousness (from neutral cue to gambling cue, controlling for baseline; sr (2) = .57, p gambling cue) mediated the relationship between problem-gambling severity and increase in urge (from neutral cue to gambling cue; κ(2) = .40, 99 % CI [.08, .71]). These findings suggest that cue-reactive altered state of consciousness is an important component of cue-reactive urge in poker-machine problem-gamblers.

  4. Phenomenological theory of mortality

    Science.gov (United States)

    Azbel, Mark Ya.

    1997-09-01

    Extensive demographic studies relate aging to the increase in mortality, terminated by the species-specific lifespan limit. Meanwhile, recent experiments demonstrate that medfly mortality decreases at older ages, and challenge a limited lifespan paradigm. This paper proves that there exists a genetically programmed probability to die at any given age, and presents its phenomenological theory. The implications of the universal mortality law crucially depend on the cohort heterogeneity. For relatively high heterogeneity the law predicts unitarily vanishing old age mortality; this is verified with medfly data. For relatively low heterogeneity it predicts a precipitous drop in mortality fluctuations in old age. This is verified with demographic data. If comprehensive studies verify a species-specific characteristic age, then that age may be genetically manipulated. If the studies verify a unitary law of mortality, the results may be generalized to all species. A phenomenological model of mortality is presented.

  5. Resonant Diphoton Phenomenology Simplified

    Panico, Giuliano; Wulzer, Andrea

    2016-01-01

    A framework is proposed to describe resonant diphoton phenomenology at hadron colliders in full generality. It can be employed for a comprehensive model-independent interpretation of the experimental data. Within the general framework, few benchmark scenarios are defined as representative of the various phenomenological options and/or of motivated new physics scenarios. Their usage is illustrated by performing a characterization of the 750 GeV excess, based on a recast of available experimental results. We also perform an assessment of which properties of the resonance could be inferred, after discovery, by a careful experimental study of the diphoton distributions. These include the spin J of the new particle and its dominant production mode. Partial information on its CP-parity can also be obtained, but only for J >= 2. The complete determination of the resonance CP properties requires studying the pattern of the initial state radiation that accompanies the resonance production.

  6. Pragmatic phenomenological types.

    Goranson, Ted; Cardier, Beth; Devlin, Keith

    2015-12-01

    We approach a well-known problem: how to relate component physical processes in biological systems to governing imperatives in multiple system levels. The intent is to further practical tools that can be used in the clinical context. An example proposes a formal type system that would support this kind of reasoning, including in machines. Our example is based on a model of the connection between a quality of mind associated with creativity and neuropsychiatric dynamics: constructing narrative as a form of conscious introspection, which allows the manipulation of one's own driving imperatives. In this context, general creativity is indicated by an ability to manage multiple heterogeneous worldviews simultaneously in a developing narrative. 'Narrative' in this context is framed as the organizing concept behind rational linearization that can be applied to metaphysics as well as modeling perceptive dynamics. Introspection is framed as the phenomenological 'tip' that allows a perceiver to be within experience or outside it, reflecting on and modifying it. What distinguishes the approach is the rooting in well founded but disparate disciplines: phenomenology, ontic virtuality, two-sorted geometric logics, functional reactive programming, multi-level ontologies and narrative cognition. This paper advances the work by proposing a type strategy within a two-sorted reasoning system that supports cross-ontology structure. The paper describes influences on this approach, and presents an example that involves phenotype classes and monitored creativity enhanced by both soft methods and transcranial direct-current stimulation. The proposed solution integrates pragmatic phenomenology, situation theory, narratology and functional programming in one framework.

    We study the phenomenological implications of Finite Unified Theories (FUTs). In particular we look at the predictions for the lightest Higgs mass and the s-spectra of two all-loop finite models with SU(5) as gauge group. We also consider a two-loop finite model with gauge group SU(3){sup 3}, which is finite if and only if there are exactly three generations. In this latter model we concetrate here only on the predictions for the third generation of quark masses.

  10. Neutrinos: Theory and Phenomenology

    Energy Technology Data Exchange (ETDEWEB)

    Parke, Stephen

    2013-10-22

    The theory and phenomenology of neutrinos will be addressed, especially that relating to the observation of neutrino flavor transformations. The current status and implications for future experiments will be discussed with special emphasis on the experiments that will determine the neutrino mass ordering, the dominant flavor content of the neutrino mass eigenstate with the smallest electron neutrino content and the size of CP violation in the neutrino sector. Beyond the neutrino Standard Model, the evidence for and a possible definitive experiment to confirm or refute the existence of light sterile neutrinos will be briefly discussed.

  11. Phenomenology and Mathematics

    During Edmund Husserl,s lifetime, modern logic and mathematics rapidly developed toward their current outlook and Husserl,s writings can be fruitfully compared and contrasted with both 19th century figures (Boole, Schroder, Weierstrass) as well as the 20th century characters (Heyting, Zermelo, Godel). Besides the more historical studies, the internal ones on Husserl alone and the external ones attempting to clarify his role in the more general context of the developing mathematics and logic, Husserl,s phenomenology offers also a systematically rich but little researched area of investigation.

    A framework to perform scans in the 19-dimensional phenomenological MSSM is developed and used to re-evaluate the ATLAS experiments' sensitivity to R-parity-conserving supersymmetry with LHC Run 2 data ($\\sqrt{s}=13$ TeV), using results from 14 separate ATLAS searches. We perform a $\\tilde{t}_1$ dedicated scan, only considering models with $m_{\\tilde{t}_1}<1$ TeV, while allowing both a neutralino ($\\tilde{\\chi}_1^0$) and a sneutrino ($\\tilde{\

  13. A method of phenomenological interviewing.

    2014-01-01

    In this article I propose a method of interviewing for descriptive phenomenological research that offers an explicit, theoretically based approach for researchers. My approach enables application of descriptive phenomenology as a total method for research, and not one just focused on data analysis. This structured phenomenological approach to interviewing applies questions based on themes of experience contextualization, apprehending the phenomenon and its clarification. The method of questioning employs descriptive and structural questioning as well as novel use of imaginative variation to explore experience. The approach will help researchers understand how to undertake descriptive phenomenological research interviews.

    2001-01-01

    Experimental results on ternary fission of sup 2 sup 5 sup 2 Cf suggest the existence of a short-lived quasi-molecular state. We present a three-center phenomenological model able to explain such a state by producing a new minimum in the deformation energy at a separation distance very close to the touching point. The shape parametrization chosen by us allows to describe the essential geometry of the systems in terms of one independent coordinate, namely, the distance between the heavy fragment centers. The shell correction (also treated phenomenologically) only produces quantitative effects; qualitatively it is not essential for the new minimum. Half-lives of some quasi-molecular states which could be formed in sup 1 sup 0 B accompanied fission of sup 2 sup 3 sup 6 U, sup 2 sup 3 sup 6 Pu, sup 2 sup 4 sup 6 Cm, sup 2 sup 5 sup 2 Cf, sup 2 sup 5 sup 2 sup , sup 2 sup 5 sup 6 Fm, sup 2 sup 5 sup 6 sup , sup 2 sup 6 sup 0 No, and sup 2 sup 6 sup 2 Rf are roughly estimated.

  17. Phenomenology and Neuroaesthetics

    Directory of Open Access Journals (Sweden)

    Elio Franzini

    2015-05-01

    Full Text Available Phenomenology is not the simple description of a fact, but rather the description of an intentional immanent moment, and it presents itself as a science of essences, and not of matter of facts. The Leib, the lived body of the phenomenological tradition, is not a generic corporeal reality, but rather an intentional subject, a transcendental reference point, on the base of which the connections between physical body and psychic body should be grasped. So, the reduction of empathy to mirror neurons amounts to an “objectivisation”, with the consequent absolutisation of a process that is a function of the Leib as intentional subject, not as a physical reality. The main task of the philosophical research, bracketed by the new “neuro” researches, thus emphasizing their theoretical limits as soon as they depart from experimental enquiries, is then to understand the conditions of possibility of cognitive procedures, that is to say, in other words, the genesis of consciousness, that in aesthetics becomes “the genesis of aesthetic consciousness”. Interdisciplinarity is already an ancient and out of fashion word, now it is the time of “dialogue”, being aware however that the “logoi” not always require synthesis, and that the unity of the corporeal reality implies, as Husserl emphasizes, very different descriptive behaviours.

  18. A Phenomenology of Islands

    Pete Hay

    2006-05-01

    Full Text Available The question is posed: is a coherent theory of islandness – nissology – possible? Faultlines within constructions of islands and islandness are noted. Some of these axes of contestation have remained latent but have the potential to be sharply divisive. Three of the identified faultlines are examined – the nature of the island ‘edge’, the import for questions of island memory and identity of massive inward and outward movements of people, and the appropriation of island ‘realness’ by those for whom ‘island’ best functions as metaphor. A case is made for the excision of the latter from the purview of island studies. Despite apparent irreconcilability within island studies’ emerging faultlines, it is argued that place theory does constitute a theoretical framing that can work for island studies. Following a brief overview of the faultlines that also exist within place studies, it is noted that the difference-respecting and identity focused nature of phenomenology of place is particularly apposite for island studies, and the paper concludes with a consideration of what a phenomenology of islands might look like.

    2009-01-01

    The present study investigated whether reactivity to nicotine-related cues would attenuate across four experimental sessions held one week apart. Participants were nineteen non-treatment seeking, nicotine-dependent males. Cue reactivity sessions were performed in an outpatient research center using in vivo cues consisting of standardized smoking-related paraphernalia (e.g., cigarettes) and neutral comparison paraphernalia (e.g., pencils). Craving ratings were collected before and after both cue presentations while physiological measures (heart rate, skin conductance) were collected before and during the cue presentations. Although craving levels decreased across sessions, smoking-related cues consistently evoked significantly greater increases in craving relative to neutral cues over all four experimental sessions. Skin conductance was higher in response to smoking cues, though this effect was not as robust as that observed for craving. Results suggest that, under the described experimental parameters, craving can be reliably elicited over repeated cue reactivity sessions. PMID:17537583

  3. Solar neutrino oscillation phenomenology

    2004-02-01

    This article summarises the status of the solar neutrino oscillation phenomenology at the end of 2002 in the light of the SNO and KamLAND results. We first present the allowed areas obtained from global solar analysis and demonstrate the preference of the solar data towards the large-mixing-angle (LMA) MSW solution. A clear confirmation in favour of the LMA solution comes from the KamLAND reactor neutrino data. the KamLAND spectral data in conjunction with the global solar data further narrows down the allowed LMA region and splits it into two allowed zones - a low $ m^{2}$ region (low-LMA) and high $ m^{2}$ region (high-LMA). We demonstrate through a projected analysis that with an exposure of 3 kton-year (kTy) KamLAND can remove this ambiguity.

  4. Fitting the Phenomenological MSSM

    AbdusSalam, S S; Quevedo, F; Feroz, F; Hobson, M

    2010-01-01

    We perform a global Bayesian fit of the phenomenological minimal supersymmetric standard model (pMSSM) to current indirect collider and dark matter data. The pMSSM contains the most relevant 25 weak-scale MSSM parameters, which are simultaneously fit using `nested sampling' Monte Carlo techniques in more than 15 years of CPU time. We calculate the Bayesian evidence for the pMSSM and constrain its parameters and observables in the context of two widely different, but reasonable, priors to determine which inferences are robust. We make inferences about sparticle masses, the sign of the $\\mu$ parameter, the amount of fine tuning, dark matter properties and the prospects for direct dark matter detection without assuming a restrictive high-scale supersymmetry breaking model. We find the inferred lightest CP-even Higgs boson mass as an example of an approximately prior independent observable. This analysis constitutes the first statistically convergent pMSSM global fit to all current data.

    These notes summarize a set of lectures on phenomenological quantum gravity which one of us delivered and the other attended with great diligence. They cover an assortment of topics on the border between theoretical quantum gravity and observational anomalies. Specifically, we review non-linear relativity in its relation to loop quantum gravity and high energy cosmic rays. Although we follow a pedagogic approach we include an open section on unsolved problems, presented as exercises for the student. We also review varying constant models: the Brans-Dicke theory, the Bekenstein varying $\\alpha$ model, and several more radical ideas. We show how they make contact with strange high-redshift data, and perhaps other cosmological puzzles. We conclude with a few remaining observational puzzles which have failed to make contact with quantum gravity, but who knows... We would like to thank Mario Novello for organizing an excellent school in Mangaratiba, in direct competition with a very fine beach indeed.

  6. Phenomenology of atmospheric neutrinos

    Directory of Open Access Journals (Sweden)

    Fedynitch Anatoli

    2016-01-01

    Full Text Available The detection of astrophysical neutrinos, certainly a break-through result, introduced new experimental challenges and fundamental questions about acceleration mechanisms of cosmic rays. On one hand IceCube succeeded in finding an unambiguous proof for the existence of a diffuse astrophysical neutrino flux, on the other hand the precise determination of its spectral index and normalization requires a better knowledge about the atmospheric background at hundreds of TeV and PeV energies. Atmospheric neutrinos in this energy range originate mostly from decays of heavy-flavor mesons, which production in the phase space relevant for prompt leptons is uncertain. Current accelerator-based experiments are limited by detector acceptance and not so much by the collision energy. This paper recaps phenomenological aspects of atmospheric leptons and calculation methods, linking recent progress in flux predictions with particle physics at colliders, in particular the Large Hadron Collider.

    Full Text Available This work has the aim of understanding the lived experiences by managers in relation to organizational changes in an enterprise in the food area, located in the State of Rio Grande do Sul, Brazil. The role of managers has been constantly evaluated and their capacity of continuous learning and also the ability of transforming the learning in good organizational results is reacquired every instant. In this work, my intention is to show, using an interpretative analysis, real and practical situations, from lived experiences. The methodological way followed was the hermeneutic phenomenological approach, trying to give a global and a contextual treatment to the theme. The results achieved offer subsides for a new look over the management practice and point out the importance of the study of what is lived, as an inspiration source for the strategic decisions in the enterprises.

  8. Cues and expressions

    2005-02-01

    Full Text Available A number of European languages have undergone a change from object-verb to verb-object order. We focus on the change in English and Icelandic, showing that while the structural change was the same, it took place at different times and different ways in the two languages, triggered by different E-language changes. As seen from the English viewpoint, low-level facts of inflection morphology may express the relevant cue for parameters, and so the loss of inflection may lead to a grammar change. This analysis does not carry over to Icelandic, as the loss of OV there took place despite rich case morphology. We aim to show how this can be explained within a cue-style approach, arguing for a universal set of cues. However, the relevant cue may be expressed differently among languages: While it may have been expressed through morphology in English, it as expressed through information structure in Icelandic. In both cases, external effects led to fewer expressions of the relevant (universal cue and a grammar change took place.

  10. [Phenomenology of dreams].

    Pringuey, Dominique

    2011-10-01

    A phenomenology of dreams searches for meaning, with the aim not only of explaining but also of understanding the experience. What and who is it for? And what about the nearly forgotten dream among the moderns, the banal returning to the nightmare, sleepiness, or dreamlike reverie. Nostalgia for the dream, where we saw a very early state of light, not a ordinaire qu duel. Regret for the dreamlike splendor exceeded by the modeling power of modern aesthetics--film and the explosion of virtual imaging technologies. Disappointment at the discovery of a cognitive permanence throughout sleep and a unique fit with the real upon awaking? An excess of methodological rigor where we validate the logic of the dream, correlating the clinical improvement in psychotherapy and the ability to interpret one's own dreams. The dangerous psychological access when the dream primarily is mine, viewed as a veiled expression of an unspoken desire, or when the dream reveals to me, in an existential conception of man, through time and space, my daily life, my freedom beyond my needs. Might its ultimate sense also mean its abolition? From the story of a famous forgotten dream, based on unexpected scientific data emerges the question: do we dream to forget? The main thing would not be consciousness but confidence, when " the sleeping man, his regard extinguished, dead to himself seizes the light in the night " (Heraclitus).

  11. Phenomenological consequences of supersymmetry

    Hinchliffe, I.; Littenberg, L.

    1982-01-01

    This report deals with the phenomenological consequences of supersymmetric theories, and with the implications of such theories for future high energy machines. It is concerned only with high energy predictions of supersymmetry; low energy consequences (for example in the K/sub o/anti K/sub o/ system) are discussed in the context of future experiments by another group, and will be mentioned briefly only in the context of constraining existing models. However a brief section is included on the implication for proton decay, although detailed experimental questions are not discussed. The report is organized as follows. Section I consists of a brief review of supersymmetry and the salient features of existing supersymmetric models; this section can be ignored by those familiar with such models since it contains nothing new. Section 2 deals with the consequences for nucleon decay of SUSY. The remaining sections then discuss the physics possibilities of various machines; e anti e in Section 3, ep in Section 4, pp (or anti pp) colliders in Section 5 and fixed target hadron machines in Section 6.

  12. Perspectives on string phenomenology

    Kane, Gordon; Kumar, Piyush

    2015-01-01

    The remarkable recent discovery of the Higgs boson at the CERN Large Hadron Collider completed the Standard Model of particle physics and has paved the way for understanding the physics which may lie beyond it. String/M theory has emerged as a broad framework for describing a plethora of diverse physical systems, which includes condensed matter systems, gravitational systems as well as elementary particle physics interactions. If string/M theory is to be considered as a candidate theory of Nature, it must contain an effectively four-dimensional universe among its solutions that is indistinguishable from our own. In these solutions, the extra dimensions of string/M Theory are “compactified” on tiny scales which are often comparable to the Planck length. String phenomenology is the branch of string/M theory that studies such solutions, relates their properties to data, and aims to answer many of the outstanding questions of particle physics beyond the Standard Model. This book contains perspectives on stri...

  15. Narcissism, self-esteem, and the phenomenology of autobiographical memories.

    Science.gov (United States)

    Jones, Lara L; Norville, Gregory A; Wright, A Michelle

    2016-09-16

    Across two studies, we investigated the influence of narcissism and self-esteem along with gender on phenomenological ratings across the four subscales of the Autobiographical Memory Questionnaire (AMQ; impact, recollection, rehearsal, and belief). Memory cues varied in valence (positive vs. negative) and agency (agentic vs. communal). In Study 2, we used different memory cues reflecting these four Valence by Agency conditions and additionally investigated retrieval times for the autobiographical memories (AMs). Results were consistent with the agency model of narcissism [Campbell, W. K., Brunell, A. B., & Finkel, E. J. (2006). Narcissism, interpersonal self-regulation, and romantic relationships: An agency model approach. In E. J. Finkel & K. D. Vohs (Eds.), Self and relationships: Connecting intrapersonal and interpersonal processes. New York, NY: Guilford], which characterises narcissists as being more concerned with agentic (self-focused) rather than communal (other-focused) positive self-relevant information. Narcissism predicted greater phenomenology across the four subscales for the positive-agentic memories (Study 1: clever; Study 2: attractive, talented) as well as faster memory retrieval times. Narcissism also predicted greater recollection and faster retrieval times for the negative-communal AMs (Study 1: rude; Study 2: annoying, dishonest). In contrast, self-esteem predicted greater phenomenology and faster retrieval times for the positive-communal AMs (Study 1: cooperative; Study 2: romantic, sympathetic). In both studies, results of LIWC analyses further differentiated between narcissism and self-esteem in the content (word usage) of the AMs.

  16. The changing face of phenomenological research: traditional and American phenomenology in nursing.

    Science.gov (United States)

    Caelli, K

    2000-05-01

    In recent years, phenomenological researchers in nursing have become concerned about the differences between traditional European phenomenology and the way phenomenology is frequently conducted in nursing. Indeed, Crotty asserts that much of the phenomenology conducted by nurses cannot be phenomenology because it does not espouse the constructionist epistemological position regarded by Husserl as essential to phenomenology. This article explores the differences between traditional European and American phenomenology and argues that the latter approach extends the phenomenological project in valuable and meaningful ways that are particularly appropriate for the health sciences.

  17. Quantum Gravity and Phenomenological Philosophy

    Science.gov (United States)

    Rosen, Steven M.

    2008-06-01

    The central thesis of this paper is that contemporary theoretical physics is grounded in philosophical presuppositions that make it difficult to effectively address the problems of subject-object interaction and discontinuity inherent to quantum gravity. The core objectivist assumption implicit in relativity theory and quantum mechanics is uncovered and we see that, in string theory, this assumption leads into contradiction. To address this challenge, a new philosophical foundation is proposed based on the phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Then, through the application of qualitative topology and hypernumbers, phenomenological ideas about space, time, and dimension are brought into focus so as to provide specific solutions to the problems of force-field generation and unification. The phenomenological string theory that results speaks to the inconclusiveness of conventional string theory and resolves its core contradiction.

    Full Text Available It is becoming apparent in modern cognitive science that the lack of knowledge about human experiential landscape implies the loss of a very important element, perhaps the very essence. Consequently, a rather new area of research has emerged recently: an attempt at a systematic observation and study of experience. This is the so-called phenomenologically inspired research (or just phenomenological research.Part of this article aims to present this new area of research – it describes the common fundaments of the field and some of its characteristic methodological derivates, relating them to the possibility of studying decision making from the first-person point-of-view, i.e. decision making as an experiential phenomenon (and not as a neurological or behavioural process. The article also presents some of the findings phenomenological studies have led to and some theoretical reflexions encouraged by these insights.

    1979-04-01

    Although there is growing openness to tailoring of assessment procedures and reports to the particular client, these efforts typically have been sporadic and incomplete. This article reviews a systematic approach to individualized assessment, one whose practices are referred to as collaborative, contextual, and interventional. Clinical examples of these practices are presented in terms of their grounding in phenomenological psychology. Prior to that, themes such as intentionality, situatedness, dialectics, structuralism, and hermeneutics are introduced briefly. Phenomenological psychology as such is not seen here as necessary for all individualized practices, but it is seen as a critical touchpoint for development of theory and further practices.

  3. Helmets: conventional to cueing

    Sedillo, Michael R.; Dixon, Sharon A.

    2003-09-01

    Aviation helmets have always served as an interface between technology and flyers. The functional evolution of helmets continued with the advent of radio when helmets were modified to accept communication components and later, oxygen masks. As development matured, interest in safety increased as evident in more robust designs. Designing helmets became a balance between adding new capabilities and reducing the helmet's weight. As the research community better defined acceptable limits of weight-tolerances with tools such as the "Knox Box" criteria, system developers added and subtracted technologies while remaining within these limits. With most helmet-mounted technologies being independent of each other, the level of precision in mounting these technologies was not as significant a concern as it is today. The attachment of new components was acceptable as long as the components served their purpose. However this independent concept has become obsolete with the dawn of modern helmet mounted displays. These complex systems are interrelated and demand precision in their attachment to the helmet. The helmets' role now extends beyond serving as a means to mount the technologies to the head, but is now instrumental in critical visual alignment of complex night vision and missile cueing technologies. These new technologies demand a level of helmet fit and component alignment previously not seen in past helmet designs. This paper presents some of the design, integration and logistical issues gleaned during the development of the Joint Helmet Mounted Cueing System (JHMCS) to include the application of head-track technologies in forensic investigations.

Particular emphasis is given to the predictions for rare processes and to the possible signals in present and future machines. (orig.).

    Background and aims It is currently under debate whether pathological buying can be considered as a behavioural addiction. Addictions have often been investigated with cue-reactivity paradigms to assess subjective, physiological and neural craving reactions. The current study aims at testing whether cue reactivity towards shopping cues is related to pathological buying tendencies. Methods A sample of 66 non-clinical female participants rated shopping related pictures concerning valence, arousal, and subjective craving. In a subgroup of 26 participants, electrodermal reactions towards those pictures were additionally assessed. Furthermore, all participants were screened concerning pathological buying tendencies and baseline craving for shopping. Results Results indicate a relationship between the subjective ratings of the shopping cues and pathological buying tendencies, even if baseline craving for shopping was controlled for. Electrodermal reactions were partly related to the subjective ratings of the cues. Conclusions Cue reactivity may be a potential correlate of pathological buying tendencies. Thus, pathological buying may be accompanied by craving reactions towards shopping cues. Results support the assumption that pathological buying can be considered as a behavioural addiction. From a methodological point of view, results support the view that the cue-reactivity paradigm is suited for the investigation of craving reactions in pathological buying and future studies should implement this paradigm in clinical samples.

  15. Naturalizing phenomenology - A philosophical imperative.

    Science.gov (United States)

    Harney, Maurita

    2015-12-01

    Phenomenology since Husserl has always had a problematic relationship with empirical science. In its early articulations, there was Husserl's rejection of 'the scientific attitude', Merleau-Ponty's distancing of the scientifically-objectified self, and Heidegger's critique of modern science. These suggest an antipathy to science and to its methods of explaining the natural world. Recent developments in neuroscience have opened new opportunities for an engagement between phenomenology and cognitive science and through this, a re-thinking of science and its hidden assumptions more generally. This is so partly because of the shortcomings of conventional mechanistically-conceived science in dealing with complex and dynamic phenomena such as climate change, brain plasticity, the behaviour of collectives, the dynamics of various microbiological processes, etc. But it is also due to recent phenomenological scholarship focussed on the 'embodied' phenomenology of Husserl's Ideen II and Merleau Ponty's later ontology of nature which have helped to extend the insights of phenomenology beyond the narrowly 'human' to an understanding of nature (which includes the human) more generally. Thus re-contextualised, phenomenology is well placed to examine some of the assumptions that give rise to the reductionism and associated scientism which has characterised conventional science in its approach to the study of natural processes. In light of this, it might be suggested that the 'anti-science' of early articulations of phenomenology is more a hostility to the underlying assumptions of science as conventionally understood than to science itself - that it is scientism rather than science that is targeted. In this paper, I aim to show how a phenomenological naturalism might be seen as a necessary step towards the development of a non-reductionist and non-scientistic approach to scientific inquiry. A key to this is a reconceptualization of nature as inclusive of meanings and of mind. It

    2005-01-01

    To begin to address the need for new displays, required by a future airspace concept to support new roles that will be assigned to flight crews, a study of potentially informative display cues was undertaken. Two cues were tested on a simple plan display - aircraft trajectory and flight corridor. Of particular interest was the speed and accuracy with which participants could detect an aircraft deviating outside its flight corridor. Presence of the trajectory cue significantly reduced participant reaction time to a deviation while the flight corridor cue did not. Although non-significant, the flight corridor cue seemed to have a relationship with the accuracy of participants judgments rather than their speed. As this is the second of a series of studies, these issues will be addressed further in future studies.

  17. Birth of a science centre. Italian phenomenology

    Directory of Open Access Journals (Sweden)

    2006-06-01

    Full Text Available In May 2004 the Balì Museum, Planetarium and interactive science museum, was opened to the public in Italy: 35 hands-on exhibits designed according to the interactive tradition of the Exploratorium in San Francisco, an astronomic observatory for educational activities, a Planetarium with 70 places. With a total investment of about three million euros, about two thirds of which were spent on restructuring the splendid eighteenth-century villa in which it is housed, the undertaking may be considered a small one in comparison with other European science centres. Three million euros: perhaps enough to cover the cost of only the splendid circular access ramp to the brand-new Cosmocaixa in Barcelona, an investment of one hundred million euros. But the interesting aspect of the story of the Balì Museum (but also of other Italian stories, as we shall see lies in the fact that this lively and advanced science centre stands in the bucolic region of the Marches, next to a small town of only 800 inhabitants (Saltara, in the Province of Pesaro and Urbino, in a municipal territory that has a total of 5000. Whereas in Italy the projects for science centres comparable with the Catalan one, for example projects for Rome and Turin, never get off the ground, smaller ones are opening in small and medium-sized towns: why is this? And what does the unusual location of the centres entail for science communication in Italy? This Focus does not claim to tell the whole truth about Italian interactive museums, but it does offer some phenomenological cues to open a debate on the cultural, economic and political premises that favour their lives.

  18. Phenomenological aspects of mirage mediation

    2009-07-15

    We consider the possibility that string theory vacua with spontaneously broken supersymmetry and a small positive cosmological constant arise due to hidden sector matter interactions, known as F-uplifting/F-downlifting. We analyze this procedure in a model-independent way in the context of type IIB and heterotic string theory. Our investigation shows that the uplifting/downlifting sector has very important consequences for the resulting phenomenology. Not only does it adjust the vacuum energy, but it can also participate in the process of moduli stabilization. In addition, we find that this sector is the dominant source of supersymmetry breaking. It leads to a hybrid mediation scheme and its signature is a relaxed mirage pattern of the soft supersymmetry breaking terms. The low energy spectra exhibit distinct phenomenological properties and di er from conventional schemes considered so far. (orig.)

  19. A phenomenological approach to psychoprosthetics.

    2013-05-01

    The phenomenology of human embodiment can advance the practitioner's understanding of the lived human body and in particular, what it means to incorporate a prosthetic device into one's body. In order for a prosthesis to be incorporated into the lived body of the patient, the prosthesis must arguably be integrated into the body schema. This article uses the phenomenology of Maurice Merleau-Ponty and others to identify three of the necessary conditions of embodiment that determine the body schema: corporeal understanding, transparency and sensorimotor feedback. It then examines the structure of each of these conditions of embodiment and how they impact the lived body's incorporation of prostheses and other artifacts. [Box: see text].

    Experimentally, Langmuir monolayers have applications in molecular optical, electronic, and sensor devices. Traditionally, Langmuir monolayers are described by a rigid rod model where the rods interact via a Leonard-Jones potential. Here, we propose effective phenomenological models and utilize Monte Carlo simulations to analyze the phase behavior and compare with experimental isotherms.

    We study the phenomenological potential of noncommutative QED as obtained from the Seiberg-Witten limit of string theories in the presence of an external B-field. We manage to define the theory free of tachyons by embedding it into {N}=4 noncommutative super Yang-Mills and breaking supersymmetry softly by adding masses to fermions and scalars. However, this requires a fine-tuning of the soft-breaking mass and the resulting theory has massive polarization for the photon.

    In this proceeding, the phenomenology of Universal Extra Dimensions (UED), in which all the Standard Model fields propagate, is explored. We focus on models with one universal extra dimension, compactified on an S{sub 1}/Z{sub 2} orbifold. We revisit calculations of Kaluza-Klein (KK) dark matter without an assumption of the KK mass degeneracy including all possible coannihilations. We then contrast the experimental signatures of low energy supersymmetry and UED.

  4. Phenomenology of stochastic exponential growth

    Science.gov (United States)

    Pirjol, Dan; Jafarpour, Farshid; Iyer-Biswas, Srividya

    2017-06-01

    Stochastic exponential growth is observed in a variety of contexts, including molecular autocatalysis, nuclear fission, population growth, inflation of the universe, viral social media posts, and financial markets. Yet literature on modeling the phenomenology of these stochastic dynamics has predominantly focused on one model, geometric Brownian motion (GBM), which can be described as the solution of a Langevin equation with linear drift and linear multiplicative noise. Using recent experimental results on stochastic exponential growth of individual bacterial cell sizes, we motivate the need for a more general class of phenomenological models of stochastic exponential growth, which are consistent with the observation that the mean-rescaled distributions are approximately stationary at long times. We show that this behavior is not consistent with GBM, instead it is consistent with power-law multiplicative noise with positive fractional powers. Therefore, we consider this general class of phenomenological models for stochastic exponential growth, provide analytical solutions, and identify the important dimensionless combination of model parameters, which determines the shape of the mean-rescaled distribution. We also provide a prescription for robustly inferring model parameters from experimentally observed stochastic growth trajectories.

    Although visual imagery is argued to be an essential component of autobiographical memory, there have been surprisingly few studies on autobiographical memory processes in blind individuals, who have had no or limited visual input. The purpose of the present study was to investigate how blindness affects retrieval and phenomenology of autobiographical memories. We asked 48 congenital/early blind and 48 sighted participants to recall autobiographical memories in response to six cue words, and to fill out the Autobiographical Memory Questionnaire measuring a number of variables including imagery, belief and recollective experience associated with each memory. Blind participants retrieved fewer memories and reported higher auditory imagery at retrieval than sighted participants. Moreover, within the blind group, participants with total blindness reported higher auditory imagery than those with some light perception. Blind participants also assigned higher importance, belief and recollection ratings to their memories than sighted participants. Importantly, these group differences remained the same for recent as well as childhood memories.

  6. Philosophy of phenomenology: how understanding aids research.

    2012-01-01

    To assist the researcher in understanding the similarities and differences between the Husserlian and Heideggerian philosophies of phenomenology, and how that philosophy can inform nursing research as a useful methodology. Nurse researchers using phenomenology as a methodology need to understand the philosophy of phenomenology to produce a research design that is philosophically congruent. However, phenomenology has a long and complex history of development, and may be difficult to understand and apply. The author draws from Heidegger (1962), Gadamer (2004), and nurse scholars and methodologists. To give the reader a sense of the development of the philosophy of phenomenology, the author briefly recounts its historical origins and interpretations, specifically related to Husserl, Heidegger and Gadamer. The author outlines the ontological and epistemological assumptions of Husserlian and Heideggerian phenomenology and guidance for methodology inspired by these philosophers. Difficulties with engaging in phenomenological research are addressed, especially the processes of phenomenological reduction and bracketing, and the lack of clarity about the methods of interpretation. Despite its complexity, phenomenology can provide the nurse researcher with indepth insight into nursing practice. An understanding of phenomenology can guide nurse researchers to produce results that have meaning in nursing patient care.

  7. Phenomenology and neurophysiological correlations: two approaches to perception research.

    Science.gov (United States)

    Spillmann, Lothar

    2009-06-01

    This article argues that phenomenological description and neurophysiological correlation complement each other in perception research. Whilst phenomena constitute the material, neuronal mechanisms are indispensable for their explanation. Numerous examples of neurophysiological correlates show that the correlation of phenomenology and neurophysiology is fruitful. Phenomena for which neuronal mechanism have been found include: (in area V1) filling-in of real and artificial scotomata, contour integration, figure-ground segregation by orientation contrast, amodal completion, and motion transparency; (in V2) modal completion, border ownership, surface transparency, and cyclopean perception; (in V3) alignment in dotted contours, and filling-in with dynamic texture; (in V4) colour constancy; (in MT) shape by accretion/deletion, grouping by coherent motion, apparent motion in motion quartets, motion in apertures, and biological motion. Results suggest that in monkey visual cortex, occlusion cues, including stereo depth, are predominantly processed in lower areas, whereas mechanisms for grouping and motion are primarily represented in higher areas. More correlations are likely to emerge as neuroscientists strive for a better understanding of visual perception. The paper concludes with a review of major achievements in visual neuroscience pertinent to the study of the phenomena under consideration.

    The Arizona Source Phenomenology Experiments (SPE) have resulted in an important dataset for the nuclear monitoring community. The 19 dedicated single-fired explosions and multiple delay-fired mining explosions were recorded by one of the most densely instrumented accelerometer and seismometer arrays ever fielded, and the data have already proven useful in quantifying confinement and excitation effects for the sources. It is very interesting to note that we have observed differences in the phenomenology of these two series of explosions resulting from the differences between the relatively slow (limestone) and fast (granodiorite) media. We observed differences at the two SPE sites in the way the rock failed during the explosions, how the S-waves were generated, and the amplitude behavior as a function of confinement. Our consortium's goal is to use the synergy of the multiple datasets collected during this experiment to unravel the phenomenological differences between the two emplacement media. The data suggest that the main difference between single-fired chemical and delay-fired mining explosion seismograms at regional distances is the increased surface wave energy for the latter source type. The effect of the delay-firing is to decrease the high-frequency P-wave amplitudes while increasing the surface wave energy because of the longer source duration and spall components. The results suggest that the single-fired explosions are surrogates for nuclear explosions in higher frequency bands (e.g., 6-8 Hz Pg/Lg discriminants). We have shown that the SPE shots, together with the mining explosions, are efficient sources of S-wave energy, and our next research stage is to postulate the possible sources contributing to the shear-wave energy.

The method is elaborated through the examples of a knot-tying orangutan in a Paris zoo and chile-eating cats in a New York apartment. We show that, when grounded in the operational framework of the phenomenological approach, the interpretation of animal life acquires a much more robust character than is usually supposed.

    Although the theoretical set-up of TMD evolution appears to be well established, its phenomenological implementations still require special attention, particularly as far as the interplay between perturbative and non-perturbative contributions is concerned. These issues have been extensively studied in Drell-Yan processes, where they seem to be reasonably under control. Instead, applying the same prescriptions and methodologies to Semi-Inclusive Deep Inelastic (SIDIS) processes is, at present, far from obvious. Some of the controversies related to the applications of TMD Evolution to SIDIS processes will be discussed with practical examples, exploring different kinematical configurations of SIDIS experiments.

    The present paper deals with the problematic nature of the phenomenological grasping of the consciousness of the body and its pathological modifications. The reasoning is oriented by the doctrine of Husserl of the so-called sentiments as the fundamentals of the experience of the own body. This basic approach does not only seem to be basically for a psychology of the consciousness of the body, but also to give the theoretical-conceptual structure for a great number of psychopathological modifications. Subsequent to a criticism of the conventional use of the term 'hallucination of the body' we attempt to chart elements of a scheme of the abnormal consciousness of the body.

  19. Phenomenology is not Phenomenalism. Is there such a thing as phenomenology of sport?

    Directory of Open Access Journals (Sweden)

    Jan Halák

    2014-06-01

    Full Text Available Background: The application of the philosophical mode of investigation called "phenomenology" in the context of sport. Objective: The goal is to show how and why the phenomenological method is very often misused in sport-related research. Methods: Interpretation of the key texts, explanation of their meaning. Results: The confrontation of concrete sport-related texts with the original meaning of the key phenomenological notions shows mainly three types of misuse - the confusion of phenomenology with immediacy, with an epistemologically subjectivist stance (phenomenalism, and with empirical research oriented towards objects in the world. Conclusions: Many of the discussed authors try to take over the epistemological validity of phenomenology for their research, which itself is not phenomenological, and it seems that this is because they are lacking such a methodological foundation. We believe that an authentically phenomenological analysis of sport is possible, but it must respect the basic distinctions that differentiate phenomenology from other styles of thinking.

    2015-12-01

    As a broad academic discipline phenomenology may be summarized as the study from a first person point of view of what appears to subjective human conscious experience. As a historical philosophical movement phenomenology was often motivated by the belief that subjective human experience is the proper foundation of all philosophy. I explore phenomena from a broader evolutionary and physical point of view. I consider a phenomenon as the subjective consequence of a physical interaction with an individual organism. In physical terms, a phenomenon requires some form of detection or measurement. What is detected is determined by the organism, and is potentially functional for the organism as a self or subject. The concept of function has meaning only for living organisms. The classical human mind-body problem is an ill-defined complicated case of the more general epistemic subject-object problem, which at the origin of life I reduce to the primitive symbol-matter problem. I argue that the first memory-based self-replicating unit, like a cell, is the most primitive case of a necessary symbol-matter distinction. The first phenomena, which include all forms or sensing, detection, and measurement, require a subject-object distinction, called the epistemic cut. It is only because of such a subject-object distinction that populations of individual subjects can selectively adapt to their environment by heritable variations. This basic evolutionary process requires distinguishing the individual's subjective phenomena from the objective events of inexorable physical laws.

  3. For the Phenomenology of Play

    Directory of Open Access Journals (Sweden)

    Roberto Farné

    2016-10-01

    Full Text Available The success of phenomenology in contemporary culture is due above all to the new approach to knowledge that has been proposed, breaking with the traditional objectivism of scientific knowledge and placing the “phenomenon” at the centre of the relationship between the subject and the world. Everyday reality, the language of concrete things, have become fully-fledged targets of philosophical thought. While Eugen Fink, student of Husserl, elects the phenomenon of play as the “symbol of the world”, the original interpretation of man’s relation to the world, in Italy Piero Bertolini redefines the scientific basis of pedagogy according to phenomenological categories and places play among the fundamental fields of experience of education. On one hand overcoming the traditional educational instrumentalisation of play, on the other its sterile reduction to a consumer experience, Bertolini brings play back to its authentic dimension in which risk, error, adventure are constituent parts, the “active ingredients” of his pedagogy.

    Full Text Available The author calls phenomenological intentionality, into question while taking it, nevertheless, as a starting point. From the analysis of the meaning of phenomena he goes back to a pathic dimension which precedes them. What happens to us or affects us and to what we respond in different ways cannot be reduced to previous horizons. Between pathos and response, there is an irreducible cleft which constitutes a special sort of time-lag. What happens to us comes is always too early; our responses always come too late. Our experience is never completely up to date. In order to explore this pre-semantic and pre-pragmatic depth of experience we need a sort of responsive reduction, which guides all meaning toward something we respond to. In conclusion, the author evokes some areas in which such a revision of phenomenology shows its effects, namely the genesis of life in bioethics, the historical elaboration of memory and the experience of the Other.

    Walters, A J

    1995-10-01

    This paper presents a comparison of the phenomenologies of Edmund Husserl and Martin Heidegger with the aim of highlighting some of the critical distinctions between these two 'schools' of phenomenology concerning the methodological implications of each approach for nursing research. Specifically, the paper examines: the implications of epistemology versus ontology; issues relating to validity; the involvement of the researcher, and aspects relating to interpretation.

    2014-11-01

    Full Text Available A contribution to the history of a formerly hotly discussed, but short-lived scientific project: neurophenomenology , the proposal of weaving together Husserlian phenomenology of consciousness and the neuroscience of brain functioning, this article traces back the opening and closing of an apparent window of opportunity, both in phenomenology and in neuroscience, for the eventually unfulfilled realization of that project.

    Lanigan, Richard L.

    John Searle's book, "Speech Acts," opened with the question, "How do words relate to the world?" This paper suggests a way of answering Searle's question by relying--in spirit if not in method--on Austin's linguistic phenomenology. The existential phenomenology approach is described in Austin's phrase as a "sharpened…

  12. [Analysis phenomenology and application to nursing research].

    Science.gov (United States)

    Huang, Yu-Ping; Kellett, Ursula M; St John, Winsome; Lee, Sheuan

    2006-04-01

    Phenomenology has been divided into three schools of thought arising from different philosophical assumptions and methods. There is descriptive phenomenology, interpretative phenomenology, and a combination of both. Phenomenology has been adopted as a study method to explore experiences in different nursing fields in Taiwan. Husserlian descriptive phenomenology professes to utilize the skills of epoché, bracketing, and phenomenological reduction not only in order to seek the essence of phenomena, but also to allow the researcher to get into the participant's life-world to gain a deeper understanding of their experience; in other words, to let the true phenomenon or essence be revealed. By contrast, Heideggerian interpretative phenomenology rejected the idea that one can completely suspend one's presuppositions, prejudices or preconceived ideas by simply Being-in-the-world. One is immersed in and absorbing from the world, so one will not be able to notice everything that one is gaining from the world. Heidegger also insisted that any interpretation is only valid when background is taken into account. This not only facilitates the researcher's deeper understanding of the other's experience, but also facilitates more accurate interpretation of context and meaning. When researchers seek to follow Husserl's idea of performing bracketing in descriptive phenomenology, in order to truly put the concept into practice, they should understand their prior assumptions and maintain a written journal of reflections throughout the study.

  13. Hadron Mass Scaling in Regge Phenomenology

    We show that Regge phenomenology is consistent with the only universal scaling law for hadron masses, M^\\ast /M=(\\alpha ^{'}/\\alpha ^{'\\ast})^{1/2}, where asterisk indicates a finite-temperature quantity. Phenomenological models further suggest the following expression of the above scaling in terms of the temperature-dependent gluon condensate: M^\\ast /M=

  14. [Reflections on phenomenological research in nursing].

    Science.gov (United States)

    Schoppmann, S; Pohlmann, M

    2000-12-01

    This essay is concerned with the question which philosophical traditions underpin the phenomenological perspective in nursing research. The word phenomenology is often used synonymously on the level of the theory of science as well as on the level of research methods. Besides the similarity in the designation of phenomenology as a philosophical tradition and as a research method, there are to be found a number of terms in the nursing literature, such as hermeneutic, interpretive or interpretative phenomenology. Therefore it is hard to differentiate between the various accounts and to use them for a concrete inquiry in nursing. The differences and the resulting consequences for phenomenological research methods shall be described whereby the ideas of Edmund Husserl and Martin Heidegger are taken into account.

  15. The phenomenology of trapped inflation

    CERN Document Server

    Pearce, Lauren; Sorbo, Lorenzo

    2016-01-01

    Trapped inflation is a mechanism in which particle production from the moving inflaton is the main source of friction in the inflaton equation of motion. The produced fields source inflaton perturbations, which dominate over the vacuum ones. We employ the set of equations for the inflaton zero mode and its perturbations which was developed in the original work on trapped inflation, and which we extend to second order in the perturbations. We build on this study by updating the experimental constraints, and by replacing the existing approximate solutions with more accurate ones. We obtain a different numerical value for the amplitude of the scalar power spectrum, and a parametrically different result for the bispectrum. This has implications for the allowed region of parameter space in models of trapped inflation, and for some of the phenomenological results obtained in this region. The main results in the allowed region are the following: monomial inflaton potentials, such as $V \\propto \\varphi,\\, \\varphi^2$ ...

  16. Phenomenology of the Sterile Neutrinos

    CERN Document Server

    Tabrizi, Zahra

    2016-01-01

    In this thesis we investigate several topics in neutrino physics, with an em- phasis on the phenomenology of the sterile neutrinos. We study the existence of a light sterile neutrino within the so called 3+1 scenario using the data of the medium baseline reactor experiments. We will also probe the parameters of the Large Extra Dimension model with the high energy atmospheric data of the IceCube experiment, and will find an equivalence between the Kaluza Klein modes and the sterile neutrinos. We will study the secret interaction of the ster- ile neutrinos which is proposed to solve the tension between cosmology and the sterile neutrino hypothesis. In addition to these, we will show that a minimal 2-Higgs-Doublet-Model extended with a U(1) or Z_2 symmetry cannot explain the smallness of the neutrino masses.

  17. Phenomenology of magnetospheric radio emissions

    Science.gov (United States)

    Carr, T. D.; Desch, M. D.; Alexander, J. K.

    1983-01-01

    Jupiter has now been observed over 24 octaves of the radio spectrum, from about 0.01 MHz to 300,000 MHz. Its radio emissions fill the entire spectral region where interplanetary electromagnetic propagation is possible at wavelengths longer than infrared. Three distinct types of radiation are responsible for this radio spectrum. Thermal emission from the atmosphere accounts for virtually all the radiation at the high frequency end. Synchrotron emission from the trapped high-energy particle belt deep within the inner magnetosphere is the dominant spectral component from about 4000 to 40 MHz. The third class of radiation consists of several distinct components of sporadic low frequency emission below 40 MHz. The decimeter wavelength emission is considered, taking into account the discovery of synchrotron emission, radiation by high-energy electrons in a magnetic field, and the present status of Jovian synchrotron phenomenology. Attention is also given to the decameter and hectometer wavelength emission, and emissions at kilometric wavelengths.

  18. Phenomenological modeling of Geometric Metasurfaces

    CERN Document Server

    Ye, Weimin; Xiang, Yuanjiang; Fan, Dianyuan; Zhang, Shuang

    2015-01-01

    Metasurfaces, with their superior capability in manipulating the optical wavefront at the subwavelength scale and low manufacturing complexity, have shown great potential for planar photonics and novel optical devices. However, vector field simulation of metasurfaces is so far limited to periodic-structured metasurfaces containing a small number of meta-atoms in the unit cell by using full-wave numerical methods. Here, we propose a general phenomenological method to analytically model metasurfaces made up of arbitrarily distributed meta-atoms based on the assumption that the meta-atoms possess localized resonances with Lorentz-Drude forms, whose exact form can be retrieved from the full wave simulation of a single element. Applied to phase modulated geometric metasurfaces, our analytical results show good agreement with full-wave numerical simulations. The proposed theory provides an efficient method to model and design optical devices based on metasurfaces.

  19. Observation and phenomenology of glueballs

    Energy Technology Data Exchange (ETDEWEB)

    Lindenbaum, S.J.

    1985-01-01

    The experimental evidence and the relevant phenomenology of glueballs are reviewed. The opinion is expressed that the glueball resonance explanation is the only viable one for the data on g/sub T/, g/sub T/sup 1//, and g/sub T/sup 11//. It is shown that alternative explanations are either incorrect, or do not fit the data, or both, leading to the conclusion that these states are probably produced by glueballs. The OZI rule is explained. Glueball masses and width are considered. Some conclusions are drawn regarding an OZI suppressed reaction ..pi../sup -/p ..-->.. phi phi n. Glueball candidates from the J/psi radiative decay are discussed. 44 refs., 16 figs. (LEW)

  20. Extended class of phenomenological universalities

    Science.gov (United States)

    Molski, Marcin

    2017-08-01

    The phenomenological universalities (PU) are extended to include quantum oscillatory phenomena, coherence and supersymmetry. It will be proved that this approach generates minimum uncertainty coherent states of time-dependent oscillators, which in the dissociation (classical) limit reduce to the functions describing growth (regression) of the systems evolving over time. The PU formalism can be applied also to construct the coherent states of space-dependent oscillators, which in the dissociation limit produce cumulative distribution functions widely used in probability theory and statistics. A combination of the PU and supersymmetry provides a convenient tool for generating analytical solutions of the Fokker-Planck equation with the drift term related to the different forms of potential energy function. The results obtained reveal existence of a new class of macroscopic quantum (or quasi-quantum) phenomena, which may play a vital role in coherent formation of the specific growth patterns in complex systems.

  1. Astroparticle physics theory and phenomenology

    CERN Document Server

    Sigl, Günter

    2017-01-01

    This books aims at giving an overview over theoretical and phenomenological aspects of particle astrophysics and particle cosmology. To be of interest for both students and researchers in neighboring fields of physics, it keeps a balance between well established foundations that will not significantly change in the future and a more in-depth treatment of selected subfields in which significant new developments have been taking place recently. These include high energy particle astrophysics, such as cosmic high energy neutrinos, the interplay between detection techniques of dark matter in the laboratory and in high energy cosmic radiation, axion-like particles, and relics of the early Universe such as primordial magnetic fields and gravitational waves. It also contains exercises and thus will be suitable for both introductory and advanced courses in astroparticle physics.

    The results of this study suggest, first, that interpersonal warmth does seem to be a personality dimension which can be reliably judged and, second, that it was possible to define and demonstrate the relevance of a number of behavioral cues for warmth. (Author)

  4. Optimal cue integration in ants.

    Wystrach, Antoine; Mangan, Michael; Webb, Barbara

    2015-10-07

    In situations with redundant or competing sensory information, humans have been shown to perform cue integration, weighting different cues according to their certainty in a quantifiably optimal manner. Ants have been shown to merge the directional information available from their path integration (PI) and visual memory, but as yet it is not clear that they do so in a way that reflects the relative certainty of the cues. In this study, we manipulate the variance of the PI home vector by allowing ants (Cataglyphis velox) to run different distances and testing their directional choice when the PI vector direction is put in competition with visual memory. Ants show progressively stronger weighting of their PI direction as PI length increases. The weighting is quantitatively predicted by modelling the expected directional variance of home vectors of different lengths and assuming optimal cue integration. However, a subsequent experiment suggests ants may not actually compute an internal estimate of the PI certainty, but are using the PI home vector length as a proxy. © 2015 The Author(s).

  5. [Phenomenology and phenomenological method: their usefulness for nursing knowledge and practice].

    Science.gov (United States)

    Vellone, E; Sinapi, N; Rastelli, D

    2000-01-01

    Phenomenology is a thought movement the main aim of which is to study human fenomena as they are experienced and lived. Key concepts of phenomenology are: the study of lived experience and subjectivity of human beings, the intentionality of consciousness, perception and interpretation. Phenomenological research method has nine steps: definition of the research topic; superficial literature searching; sample selection; gathering of lived experiences; analysis of lived experiences; written synthesis of lived experiences; validation of written synthesis; deep literature searching; writing of the scientific document. Phenomenology and phenomenological method are useful for nursing either to develop knowledge or to guide practice. Qualitative-phenomenological and quantitative-positivistic research are complementary: the first one guides clinicians towards a person-centered approach, the second one allows the manipulation of phenomena which can damage health, worsen illness or decrease the quality of life of people who rely on nursing care.

    Hubbard, Timothy L.; Kumar, Anuradha Mohan; Carp, Charlotte L.

    2009-01-01

    Effects of a spatial cue on representational momentum were examined. If a cue was present during or after target motion and indicated the location at which the target would vanish or had vanished, forward displacement of that target decreased. The decrease in forward displacement was larger when cues were present after target motion than when cues…

    This work explores the effect of spatial cueing on number processing. Participants performed a parity judgment task. However, shortly before the target number, a cue (arrow pointing to left, arrow pointing to right or a cross) was centrally presented. In Experiment 1, in which responses were lateralized, the cue direction modulated the interaction…

  8. Toys library: A phenomenological study

    2016-04-01

    Full Text Available In this survey, it is aimed to determine parents’ thoughts of children using a toys library opened within a public library. The concept of a “Toys Library”, which is growing in popularity, combines the perceptions of toys and library, based on the principle of lending toys out to disadvantaged children. This study is a qualitative phenomenological research in which parents’ thoughts and knowledge gathered from the literature are examined. The study group is composed of 306 children, 134 from pre-schools and 172 from primary schools, and their parents. In this research, which is based on proper sampling method, statistical data were obtained from the software prepared for the toys library and qualitative data obtained from semi-structured interviews over a 12 month period. As a result of content analysis of 48 parents interviews recorded via video, it has been concluded that the project contributed to the functioning of the public libraries, has fully met the children’s toys needs, and has positively affected the children’s character and social development. As a result of this project, it is hoped that the survey will be seen as a reference point for toy libraries planned to be opened elsewhere.

    Among three typical energy scales, a neutrino mass scale (m{sub {nu}}{approx}0.1eV), a GUT scale (M{sub GUT}{approx}10{sup 16}GeV), and a TeV-scale (M{sub NP}{approx}1TeV), there is a fascinating relation of M{sub NP} Asymptotically-Equal-To {radical}(m{sub {nu}} Dot-Operator M{sub GUT}) The TeV-scale, M{sub NP}, is a new physics scale beyond the standard model which is regarded as 'supersymmetry' (SUSY) in this letter. We investigate phenomenology of SUSY SU(5) GUT with neutrinophilic Higgs, which realizes the above relation dynamically as well as the suitable magnitude of Dirac mass, m{sub {nu}}, through a tiny vacuum expectation value of neutrinophilic Higgs. As a remarkable feature of this model, accurate gauge coupling unification can be achieved as keeping with a proton stability. We also evaluate flavor changing processes in quark/lepton sectors.

  10. Cue salience influences the use of height cues in reorientation in pigeons (Columba livia).

    Science.gov (United States)

    Du, Yu; Mahdi, Nuha; Paul, Breanne; Spetch, Marcia L

    2016-07-01

    Although orienting ability has been examined with numerous types of cues, most research has focused only on cues from the horizontal plane. The current study investigated pigeons' use of wall height, a vertical cue, in an open-field task and compared it with their use of horizontal cues. Pigeons were trained to locate food in 2 diagonal corners of a rectangular enclosure with 2 opposite high walls as height cues. Before each trial, pigeons were rotated to disorient them. In training, pigeons could use either the horizontal cues from the rectangular enclosure or the height information from the walls to locate the food. In testing, the apparatus was modified to provide (a) horizontal cues only, (b) height cues only, and (c) both height and horizontal cues in conflict. In Experiment 1 the lower and high walls, respectively, were 40 and 80 cm, whereas in Experiment 2 they were made more perceptually salient by shortening them to 20 and 40 cm. Pigeons accurately located the goal corners with horizontal cues alone in both experiments, but they searched accurately with height cues alone only in Experiment 2. When the height cues conflicted with horizontal cues, pigeons preferred the horizontal cues over the height cues in Experiment 1 but not in Experiment 2, suggesting that perceptual salience influences the relative weighting of cues.

  12. Phenomenological gravitational waveforms from spinning coalescing binaries

    CERN Document Server

    Sturani, R; Cadonati, L; Guidi, G M; Healy, J; Shoemaker, D; Vicere', A

    2010-01-01

    An accurate knowledge of the coalescing binary gravitational waveform is crucial for match filtering techniques, which are currently used in the observational searches performed by the LIGO-Virgo collaboration. Following an earlier paper by the same authors we expose the construction of analytical phenomenological waveforms describing the signal sourced by generically spinning binary systems. The gap between the initial inspiral part of the waveform, described by spin-Taylor approximants, and its final ring-down part, described by damped exponentials, is bridged by a phenomenological phase calibrated by comparison with the dominant spherical harmonic mode of a set of waveforms including both numerical and phenomenological waveforms of a different type. All waveforms considered describe equal mass systems with dimension-less spin magnitudes equal to 0.6. The noise-weighted overlap integral between numerical and phenomenological waveforms ranges between 0.93 and 0.98 for a wide span of mass values.

  13. Phenomenology and its application in medicine.

    Science.gov (United States)

    Carel, Havi

    2011-02-01

    Phenomenology is a useful methodology for describing and ordering experience. As such, phenomenology can be specifically applied to the first person experience of illness in order to illuminate this experience and enable health care providers to enhance their understanding of it. However, this approach has been underutilized in the philosophy of medicine as well as in medical training and practice. This paper demonstrates the usefulness of phenomenology to clinical medicine. In order to describe the experience of illness, we need a phenomenological approach that gives the body a central role and acknowledges the primacy of perception. I present such a phenomenological method and show how it could usefully illuminate the experience of illness through a set of concepts taken from Merleau-Ponty. His distinction between the biological body and the body as lived, analysis of the habitual body, and the notions of motor intentionality and intentional arc are used to capture the experience of illness. I then discuss the applications this approach could have in medicine. These include narrowing the gap between objective assessments of well-being in illness and subjective experiences which are varied and diverse; developing a more attuned dialogue between physicians and patients based on a thick understanding of illness; developing research methods that are informed by phenomenology and thus go beyond existing qualitative methods; and providing medical staff with a concrete understanding of the impact of illness on the life-world of patients.

  14. Schizophrenia: from phenomenology to neurobiology.

    Science.gov (United States)

    Wong, Albert Hung Choy; Van Tol, Hubert H M

    2003-05-01

    Schizophrenia is a common and debilitating illness, characterized by chronic psychotic symptoms and psychosocial impairment that exact considerable human and economic costs. The literature in electronic databases as well as citations and major articles are reviewed with respect to the phenomenology, pathology, treatment, genetics and neurobiology of schizophrenia. Although studied extensively from a clinical, psychological, biological and genetic perspective, our expanding knowledge of schizophrenia provides only an incomplete understanding of this complex disorder. Recent advances in neuroscience have allowed the confirmation or refutation of earlier findings in schizophrenia, and permit useful comparisons between the different levels of organization from which the illness has been studied. Schizophrenia is defined as a clinical syndrome that may include a collection of diseases that share a common presentation. Genetic factors are the most important in the etiology of the disease, with unknown environmental factors potentially modulating the expression of symptoms. Schizophrenia is a complex genetic disorder in which many genes may be implicated, with the possibility of gene-gene interactions and a diversity of genetic causes in different families or populations. A neurodevelopmental rather than degenerative process has received more empirical support as a general explanation of the pathophysiology, although simple dichotomies are not particularly helpful in such a complicated disease. Structural brain changes are present in vivo and post-mortem, with both histopathological and imaging studies in overall agreement that the temporal and frontal lobes of the cerebral cortex are the most affected. Functional imaging, neuropsychological testing and clinical observation are also generally consistent in demonstrating deficits in cognitive ability that correlate with abnormalities in the areas of the brain with structural abnormalities.

  15. Phenomenology of Sarks and Dileptons

    Science.gov (United States)

    Chaudhry, Jyoti

    We have studied three extensions of the standard model; the sark model, the vector quark model and the 331 model. The sark model has a gauge group SU(2) _{X}otimes SU(3)_{C} otimes SU(2)_{S}otimes U(1) _{Q}, where all gauge symmetries are unbroken. The vector-quark model contains an extra vector-like quark doublet. Finally, the 331 model has a gauge group SU(3)_{C}otimes SU(3)_{L}otimes U(1)_{X } where SU(3)otimes U(1)_ {X} contains the standard electroweak group SU(2)_{L}otimes U(1) _{Y}. This model contains three extended fermion families with the third family treated differently and additional vector gauge bosons. In the sark model, the number of quark-lepton families is constrained to three by the asymptotic freedom for the SU(2)_{X} group. Further, quantization of the electric charge is achieved by the anomaly cancellation conditions. Neutral sark baryons, called narks, are candidates for the cosmological dark matter having the characteristics designed for WIMPS. Further phenomenological implications of sarks are analyzed including electron-positron annihilation, Z^{0 } decay, flavor-changing neutral currents, baryon-number non-conservation, sarkonium and the neutron electric dipole moment. Next, we have studied the CP violation parameter Re(epsilon^'/epsilon) in the vector-quark model and also in the 331 model. For a given value of m_{t}, the vector quark model tends to reduce Re(epsilon ^'/epsilon) whereas the 331 model tends to increase it. If m_{t } is discovered around 150 GeV and the lower experimental value for Re(epsilon^ '/epsilon) (0.74+/- 0.60times 10^{-3}, Fermilab) is confirmed, the standard model is acceptable. But, if its higher value (2.3+/- 0.65times 10 ^{-3}, CERN) persists, a dynamics like the 331 model seems to be favored. Lastly, we have looked for the signatures of the dileptons in e^-p and e ^-e^+ colliders. At HERA, with the center-of-mass energy 314 GeV, a dilepton mass above 150 GeV is inaccessible but at LEPII-LHC, with a 1790 Ge

    Full Text Available Objective: To evaluate the importance of phenomenological aspects of the cognitive rumination (CR construct in current empirical psychiatric research.Method: We searched SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE, SpringerLink, Cambridge Journals and Web of Science between February and March of 2014 for studies whose title and topic included the following keywords: cognitive rumination; rumination response scale; and self-reflection. The inclusion criteria were: empirical clinical study; CR as the main object of investigation; and study that included a conceptual definition of CR. The studies selected were published in English in biomedical journals in the last 10 years. Our phenomenological analysis was based on Karl Jaspers' General Psychopathology.Results: Most current empirical studies adopt phenomenological cognitive elements in conceptual definitions. However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models.Conclusion: Empirical studies fail when evaluating phenomenological aspects of the cognitive elements of the CR construct. Psychopathology and phenomenology may help define the characteristics of CR elements and may contribute to their understanding and hierarchical organization as a construct. A review of the psychopathology principles established by Jasper may clarify some of these issues.

  17. Phenomenology as a resource for patients.

    Science.gov (United States)

    Carel, Havi

    2012-04-01

    Patient support tools have drawn on a variety of disciplines, including psychotherapy, social psychology, and social care. One discipline that has not so far been used to support patients is philosophy. This paper proposes that a particular philosophical approach, phenomenology, could prove useful for patients, giving them tools to reflect on and expand their understanding of their illness. I present a framework for a resource that could help patients to philosophically examine their illness, its impact on their life, and its meaning. I explain the need for such a resource, provide philosophical grounding for it, and outline the epistemic and existential gains philosophy offers. Illness often begins as an intrusion on one's life but with time becomes a way of being. I argue that this transition impacts on core human features such as the experience of space and time, human abilities, and adaptability. It therefore requires philosophical analysis and response. The paper uses ideas from Husserl and Merleau-Ponty to present such a response in the form of a phenomenological toolkit for patients. The toolkit includes viewing illness as a form of phenomenological reduction, thematizing illness, and examining illness as altering the ill person's being in the world. I suggest that this toolkit could be offered to patients as a workshop, using phenomenological concepts, texts, and film clips to reflect on illness. I conclude by arguing that examining illness as a limit case of embodied existence deepens our understanding of phenomenology.

We searched SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE), SpringerLink, Cambridge Journals and Web of Science between February and March of 2014 for studies whose title and topic included the following keywords: cognitive rumination; rumination response scale; and self-reflection. The inclusion criteria were: empirical clinical study; CR as the main object of investigation; and study that included a conceptual definition of CR. The studies selected were published in English in biomedical journals in the last 10 years. Our phenomenological analysis was based on Karl Jaspers' General Psychopathology. Most current empirical studies adopt phenomenological cognitive elements in conceptual definitions. However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models. Empirical studies fail when evaluating phenomenological aspects of the cognitive elements of the CR construct. Psychopathology and phenomenology may help define the characteristics of CR elements and may contribute to their understanding and hierarchical organization as a construct. A review of the psychopathology principles established by Jasper may clarify some of these issues.

  19. The current dialogue between phenomenology and psychiatry: a problematic misunderstanding.

    2015-11-01

    A revival of the dialogue between phenomenology and psychiatry currently takes place in the best international journals of psychiatry. In this article, we analyse this revival and the role given to phenomenology in this context. Although this dialogue seems at first sight interesting, we show that it is problematic. It leads indeed to use phenomenology in a special way, transforming it into a discipline dealing with empirical facts, so that what is called "phenomenology" has finally nothing to do with phenomenology. This so-called phenomenology tallies however with what we have always called semiology. We try to explain the reasons why phenomenology is misused in that way. In our view, this transformation of phenomenology into an empirical and objectifying discipline is explained by the role attributed to phenomenology by contemporary authors, which is to solve the problems raised by the Diagnostic and Statistical Manual of Mental Disorders.

    2011-01-01

    International audience; In this paper we study the estimation of dense, instantaneous 3D motion fields over a non-rigidly moving surface observed by multi-camera systems. The motivation arises from multi-camera applications that require motion information, for arbitrary subjects, in order to perform tasks such as surface tracking or segmentation. To this aim, we present a novel framework that allows to efficiently compute dense 3D displacement fields using low level visual cues and geometric con...

  1. Heidegger’s phenomenology of the invisible

    Directory of Open Access Journals (Sweden)

    Andrzej SERAFIN

    2016-12-01

    Full Text Available Martin Heidegger has retrospectively characterized his philosophy as “phenomenology of the invisible”. This paradoxical formula suggests that the aim of his thinking was to examine the origin of the phenomena. Furthermore, Heidegger has also stated that his philosophy is ultimately motivated by a theological interest, namely the question of God’s absence. Following the guiding thread of those remarks, this essay analyzes the essential traits of Heidegger’s thought by interpreting them as an attempt to develop a phenomenology of the invisible. Heidegger’s attitude towards physics and metaphysics, his theory of truth, his reading of Aristotle, his concept of Dasein, his understanding of nothingness are all situated within the problematic context of the relation between the invisible and the revealed. Heidegger’s thought is thereby posited at the point of intersection of phenomenology, ontology, and theology.

  2. The Nonlinear World Conceptual Analysis and Phenomenology

    CERN Document Server

    Oono, Yoshitsugu

    2013-01-01

    The most important characteristic of the “world filled with nonlinearity” is the existence of scale interference: disparate space–time scales interfere with each other. Thus, the effects of unknowable scales invade the world that we can observe directly. This leads to various peculiar phenomena such as chaos, critical phenomena, and complex biological phenomena, among others. Conceptual analysis and phenomenology are the keys to describe and understand phenomena that are subject to scale interference, because precise description of unfamiliar phenomena requires precise concepts and their phenomenological description. The book starts with an illustration of conceptual analysis in terms of chaos and randomness, and goes on to explain renormalization group philosophy as an approach to phenomenology. Then, abduction is outlined as a way to express what we have understood about the world. The book concludes with discussions on how we can approach genuinely complex phenomena, including biological phenomena. T...

  3. Phenomenology as research method or substantive metaphysics? An overview of phenomenology's uses in nursing.

    Science.gov (United States)

    Earle, Vicki

    2010-10-01

    In exploring phenomenological literature, it is evident that the term 'phenomenology' holds rather different meanings depending upon the context. Phenomenology has been described as both a philosophical movement and an approach to human science research. The phenomenology of Husserl, Heidegger, Gadamer, and Merleau-Ponty was philosophical in nature and not intended to provide rules or procedures for conducting research. The Canadian social scientist, van Manen, however, introduced specific guidelines for conducting human science research, which is rooted in hermeneutic phenomenology and this particular method has been employed in professional disciplines such as education, nursing, clinical psychology, and law. The purpose of this paper is to explore the difference between the phenomenological method as described by van Manen and that of other philosophers such as Husserl, Heidegger, Gadamer, and Merleau-Ponty. In so doing, the author aims to address the blurred boundaries of phenomenology as a research method and as a philosophical movement and highlight the influence of these blurred boundaries on nursing knowledge development.

    We consider scenarios in the next-to-minimal supersymmetric model (NMSSM) where the CP-odd and charged Higgs bosons are very light. As we demonstrate, these can be obtained as simple deformations of existing phenomenological MSSM benchmarks scenarios with parameters defined at the weak scale. This offers a direct and meaningful comparison to the MSSM case. Applying a wide set of up-to-date constraints from both high-energy collider and flavour physics, the Higgs boson masses and couplings are studied in viable parts of parameter space. The LHC phenomenology of the light Higgs scenario for neutral and charged Higgs boson searches is discussed. (orig.)

  5. Statistical turbulence theory and turbulence phenomenology

    Herring, J. R.

    1973-01-01

    The application of deductive turbulence theory for validity determination of turbulence phenomenology at the level of second-order, single-point moments is considered. Particular emphasis is placed on the phenomenological formula relating the dissipation to the turbulence energy and the Rotta-type formula for the return to isotropy. Methods which deal directly with most or all the scales of motion explicitly are reviewed briefly. The statistical theory of turbulence is presented as an expansion about randomness. Two concepts are involved: (1) a modeling of the turbulence as nearly multipoint Gaussian, and (2) a simultaneous introduction of a generalized eddy viscosity operator.

    Using a global Bayesian analysis, it is shown how the results from 7 and 8 $\\textrm{TeV}$ searches for supersymmetry performed by the CMS experiment constrain the Minimal Supersymmetric StandardModel (MSSM). The study is performed within the framework of the phenomenologicalMSSM (pMSSM), a 19-parameter realization of the R-parity conserving weak scale MSSM, that captures most of the latter's phenomenological features and which,therefore, permits robust conclusions to be drawn about the MSSM.

  8. Phenomenology in pediatric cancer nursing research.

    Science.gov (United States)

    Fochtman, Dianne

    2008-01-01

    What does it mean to have cancer as a child or adolescent? To understand this, researchers must study the illness from the child's point of view and listen to these children's descriptions of their "lived world." Phenomenology is a qualitative research methodology that can be used to discover and interpret meaning. To use phenomenology congruently, the philosophical background must be understood as well as the adaptation of the philosophical basis to research in the caring sciences. Only when clinicians truly understand the meaning of this illness to the child can they design nursing interventions to ease suffering and increase quality of life in children and adolescents with cancer.

  9. [An existential-phenomenological approach to consciousness].

    Science.gov (United States)

    Langle, A

    2014-01-01

    The human beings are characterized as subjects. Their essence is understood as Person. A treatment which does not consider the subjective and the Person would not correspond their essence. For a feeling and autonomous being, consciousness plays a role but cannot fully correspond the being a person. This has a therapeutic impact on the treatment of unconscious patients and gives the treatment a specific access. Some instructions for the therapeutic application of the phenomenological-existential concept and the phenomenological attitude towards unconscious or brain traumatized patients are given. The role of consciousness for being human is briefly reflected from an existential perspective.

    Full Text Available It is my intention to elucidate what are the foundations of the truth of those propositions that express what the phenomenological tradition since Husserl has called a «material a priori». My aim is not to paraphrase Husserl, but to try to specify the evidence we have of such claims. I aim to consider to what extent at the basis of such an evidence lays linguistic meaning and how the traditional phenomenological understanding of that evidence may be improved resorting to ideas that are close in spirit to the latter Wittgenstein.

  14. Cue-switch costs in task-switching: cue priming or control processes?

    Science.gov (United States)

    Grange, James A; Houghton, George

    2010-09-01

    In the explicitly cued task-switching paradigm, two cues per task allow separation of costs associated with switching cues from costs of switching tasks. Whilst task-switch costs have become controversial, cue-switch costs are robust. The processes that contribute to cue-switch costs are under-specified in the literature: they could reflect perceptual priming of cue properties, or priming of control processes that form relevant working memory (WM) representations of task demands. Across two experiments we manipulated cue-transparency in an attention-switching design to test the contrasting hypotheses of cue-switch costs, and show that such costs emerge from control processes of establishing relevant WM representations, rather than perceptual priming of the cue itself. When the cues were maximally transparent, cue-switch costs were eradicated. We discuss the results in terms of recent theories of cue encoding, and provide a formal definition of cue-transparency in switching designs and its relation to WM representations that guide task performance.

  16. The status of Husserlian phenomenology in caring research.

    Science.gov (United States)

    Giorgi, A

    2000-01-01

    In a recent article, Paley criticized nursing research that claimed to be phenomenological and recommended that all reference to Husserl be dropped by nurses following certain qualitative procedures. The purpose of this article is to demonstrate that Paley is wrong in his recommendation by showing that Paley (i) does not distinguish scientific phenomenology from philosophical phenomenology; (ii) is severely limited with respect to scholarly references that legitimate and articulate the scientific phenomenological method; (iii) seems to be unaware of the precedents for attempting scholarly analyses of the experiences and behaviors of others; and (iv) seems to be unaware of the internal history of the development of the scientific phenomenological method, which would show its close relationship to Husserl. Although deficiencies in nursing phenomenological research can be found, the solution is not to drive the researchers away from phenomenology, but to encourage them to apply the scientific phenomenological method in a better way.

  17. Dreaming Consciousness: A Contribution from Phenomenology

    Directory of Open Access Journals (Sweden)

    Nicola Zippel

    2016-08-01

    Full Text Available The central aim of this paper is to offer a historical reconstruction of phenomenological studies on dreaming and to put forward a draft for a phenomenological theory of the dream state. Prominent phenomenologists have offered an extremely valuable interpretation of the dream as an intentional process, stressing its relevance in understanding the complexity of the mental life of subject, the continuous interplay between reality and unreality, and the possibility of building parallel spheres of experience influencing the development of personal identity. Taking into consideration the main characteristics of dream experience emphasized by these scholars, in the final part of the paper I propose to elaborate a new phenomenology of dreaming, which should be able to offer a theoretical description of dream states. My sketched proposal is based on Eugen Fink’s notion of the dream as “presentification”. By combining the past and the present of phenomenological investigation, I aim at suggesting a philosophical framework to explain the intentional features of dreaming as Erlebnis.

  3. Medical phenomenology and stroke rehabilitation: an introduction.

    Science.gov (United States)

    Goldberg, Gary

    2011-01-01

    This issue of Topics in Stroke Rehabilitation explores the theme of medical phenomenology and stroke rehabilitation through open peer commentary format. The theme is introduced by a brief summary and overview of phenomenology as a branch of philosophy whose focus is the development of methodology for describing and ordering human experience. The application of this philosophical approach to medicine in general and stroke rehabilitation in particular is then considered. An approach to patients informed by both phenomenology and science provides a more complete, holistic, and humanistic framework than science alone. Phenomenology helps the clinician to understand the importance of narrative, the process of adaptation at the level of the integrated whole person, and the important role of context in determining how recovery unfolds. Embodiment is presented as an organizing principle that links the nature of conscious experience in the lived body and the basic transformation in experience and function associated with an acquired pathology such as stroke. Finally, the nature of open peer commentary is considered and introduced in terms of how it has been specifically implemented in this issue of Topics in Stroke Rehabilitation.

  8. Why natural science needs phenomenological philosophy.

    Science.gov (United States)

    Rosen, Steven M

    2015-12-01

    Through an exploration of theoretical physics, this paper suggests the need for regrounding natural science in phenomenological philosophy. To begin, the philosophical roots of the prevailing scientific paradigm are traced to the thinking of Plato, Descartes, and Newton. The crisis in modern science is then investigated, tracking developments in physics, science's premier discipline. Einsteinian special relativity is interpreted as a response to the threat of discontinuity implied by the Michelson-Morley experiment, a challenge to classical objectivism that Einstein sought to counteract. We see that Einstein's efforts to banish discontinuity ultimately fall into the "black hole" predicted in his general theory of relativity. The unavoidable discontinuity that haunts Einstein's theory is also central to quantum mechanics. Here too the attempt has been made to manage discontinuity, only to have this strategy thwarted in the end by the intractable problem of quantum gravity. The irrepressible discontinuity manifested in the phenomena of modern physics proves to be linked to a merging of subject and object that flies in the face of Cartesian philosophy. To accommodate these radically non-classical phenomena, a new philosophical foundation is called for: phenomenology. Phenomenological philosophy is elaborated through Merleau-Ponty's concept of depth and is then brought into focus for use in theoretical physics via qualitative work with topology and hypercomplex numbers. In the final part of this paper, a detailed summary is offered of the specific application of topological phenomenology to quantum gravity that was systematically articulated in The Self-Evolving Cosmos (Rosen, 2008a).

  9. Guiding Attention by Cooperative Cues

    Institute of Scientific and Technical Information of China (English)

    KangWoo Lee

    2008-01-01

    A common assumption in visual attention is based on the rationale of "limited capacity of information pro-ceasing". From this view point there is little consideration of how different information channels or modules are cooperating because cells in processing stages are forced to compete for the limited resource. To examine the mechanism behind the cooperative behavior of information channels, a computational model of selective attention is implemented based on two hypotheses. Unlike the traditional view of visual attention, the cooperative behavior is assumed to be a dynamic integration process between the bottom-up and top-down information. Furthermore, top-down information is assumed to provide a contextual cue during selection process and to guide the attentional allocation among many bottom-up candidates. The result from a series of simulation with still and video images showed some interesting properties that could not be explained by the competitive aspect of selective attention alone.

  10. How rats combine temporal cues.

    Guilhardi, Paulo; Keen, Richard; MacInnis, Mika L M; Church, Russell M

    2005-05-31

    The procedures for classical and operant conditioning, and for many timing procedures, involve the delivery of reinforcers that may be related to the time of previous reinforcers and responses, and to the time of onsets and terminations of stimuli. The behavior resulting from such procedures can be described as bouts of responding that occur in some pattern at some rate. A packet theory of timing and conditioning is described that accounts for such behavior under a wide range of procedures. Applications include the food searching by rats in Skinner boxes under conditions of fixed and random reinforcement, brief and sustained stimuli, and several response-food contingencies. The approach is used to describe how multiple cues from reinforcers and stimuli combine to determine the rate and pattern of response bouts.

  18. Putting phenomenology in its place: some limits of a phenomenology of medicine.

    Science.gov (United States)

    Sholl, Jonathan

    2015-12-01

    Several philosophers have recently argued that phenomenology is well-suited to help understand the concepts of health, disease, and illness. The general claim is that by better analysing how illness appears to or is experienced by ill individuals--incorporating the first-person perspective--some limitations of what is seen as the currently dominant third-person or 'naturalistic' approaches to understand health and disease can be overcome. In this article, after discussing some of the main insights and benefits of the phenomenological approach, I develop three general critiques of it. First, I show that what is often referred to as naturalism tends to be misunderstood and/or misrepresented, resulting in straw-man arguments. Second, the concept of normality is often problematically employed such that some aspects of naturalism are actually presupposed by many phenomenologists of medicine. Third, several of the key phenomenological insights and concepts, e.g. having vs. being a body, the alienation of illness, the epistemic role of the first-person perspective, and the idea of health within illness, each bring with them new problems that limit their utility. While acknowledging the possible contributions of phenomenology, these criticisms point to some severe limitations of bringing phenomenological insights to bear on the problems facing philosophy of medicine that should be addressed if phenomenology is to add anything substantially new to its debates.

    2011-01-01

    behaviour is thought to be rare in one of the classic examples of cooperation--social insect colonies--because the colony-level costs of individual selfishness select against cues that would allow workers to recognize their closest relatives. In accord with this, previous studies of wasps and ants have...... found little or no kin information in recognition cues. Here, we test the hypothesis that social insects do not have kin-informative recognition cues by investigating the recognition cues and relatedness of workers from four colonies of the ant Acromyrmex octospinosus. Contrary to the theoretical...... prediction, we show that the cuticular hydrocarbons of ant workers in all four colonies are informative enough to allow full-sisters to be distinguished from half-sisters with a high accuracy. These results contradict the hypothesis of non-heritable recognition cues and suggest that there is more potential...

  20. Gender differences in autobiographical memory for everyday events: Retrieval elicited by SenseCam Images vs. Verbal Cues

    Science.gov (United States)

    St Jacques, Peggy L.; Conway, Martin A.; Cabeza, Roberto

    2011-01-01

    Gender differences are frequently observed in autobiographical memory (AM). Few studies, however, have investigated the neural basis of potential gender differences in AM. In the present functional MRI (fMRI) study we investigated gender differences in AMs elicited using dynamic visual images vs. verbal cues. We used a novel technology called a SenseCam, a wearable device that automatically takes thousands of photographs. SenseCam differs considerably from other prospective methods of generating retrieval cues because it does not disrupt the ongoing experience. This allowed us to control for potential gender differences in emotional processing and elaborative rehearsal, while manipulating how the AMs were elicited. We predicted that males would retrieve more richly experienced AMs elicited by the SenseCam images vs. the verbal cues, whereas females would show equal sensitivity to both cues. The behavioral results indicated that there were no gender differences in subjective ratings of reliving, importance, vividness, emotion and uniqueness, suggesting that gender differences in brain activity were not due to differences in these measures of phenomenological experience. Consistent with our predictions, the fMRI results revealed that males showed a greater difference in functional activity associated with the rich experience of SenseCam vs. Verbal Cues, than did females.

    Several scientific psychologists consider the approach for the study of perceptive problems of the Experimental Phenomenology is problematic, namely that the phenomenological demonstrations are subjectively based and they do not produce quantifiable results. The aim of this study is to show that Experimental Phenomenology can lead to conclusions objective and quantifiable and propose a procedure allowing to obtain objective measuring using the Rasch mathematical model able to describe the experimental data gathered in Experimental Phenomenology procedures. In order to demonstrate this, a Psychophysics simulated study is proposed. It is possible to carry out a fundamental measurement starting from Experimental Phenomenology by way of the Theory of Conjoint Measurement.

  2. Birth of a science centre. Italian phenomenology (Italian original version

    Full Text Available In May 2004 the Balì Museum, Planetarium and interactive science museum, was opened to the public in Italy: 35 hands-on exhibits designed according to the interactive tradition of the Exploratorium in San Francisco, an astronomic observatory for educational activities, a Planetarium with 70 places. With a total investment of about three million euros, about two thirds of which were spent on restructuring the splendid eighteenth-century villa in which it is housed, the undertaking may be considered a small one in comparison with other European science centres. Three million euros: perhaps enough to cover the cost of only the splendid circular access ramp to the brand-new Cosmocaixa in Barcelona, an investment of one hundred million euros. But the interesting aspect of the story of the Balì Museum (but also of other Italian stories, as we shall see lies in the fact that this lively and advanced science centre stands in the bucolic region of the Marches, next to a small town of only 800 inhabitants (Saltara, in the Province of Pesaro and Urbino, in a municipal territory that has a total of 5000. Whereas in Italy the projects for science centres comparable with the Catalan one, for example projects for Rome and Turin, never get off the ground, smaller ones are opening in small and medium-sized towns: why is this? And what does the unusual location of the centres entail for science communication in Italy? This Focus does not claim to tell the whole truth about Italian interactive museums, but it does offer some phenomenological cues to open a debate on the cultural, economic and political premises that favour their lives.

  3. Phenomenology and adapted physical activity: philosophy and professional practice.

    2014-01-01

    Through the increased use of qualitative research methods, the term phenomenology has become a quite familiar notion for researchers in adapted physical activity (APA). In contrast to this increasing interest in phenomenology as methodology, relatively little work has focused on phenomenology as philosophy or as an approach to professional practice. Therefore, the purpose of this article is to examine the relevance of phenomenology as philosophy and as pedagogy to the field of APA. First, phenomenology as philosophy is introduced through three key notions, namely the first-person perspective, embodiment, and life-world. The relevance of these terms to APA is then outlined. Second, the concept of phenomenological pedagogy is introduced, and its application and potential for APA are discussed. In conclusion, it is argued that phenomenology can help theorize ways of understanding human difference in movement contexts and form a basis of action-oriented research aiming at developing professional practice.

    Full Text Available The current study used remote corneal reflection eye-tracking to examine the relationship between motor experience and action anticipation in 13-month-old infants. To measure online anticipation of actions infants watched videos where the actor’s hand provided kinematic information (in its orientation about the type of object that the actor was going to reach for. The actor’s hand orientation either matched the orientation of a rod (congruent cue or did not match the orientation of the rod (incongruent cue. To examine relations between motor experience and action anticipation, we used a 2 (reach first vs. observe first x 2 (congruent kinematic cue vs. incongruent kinematic cue between-subjects design. We show that 13-month-old infants in the observe first condition spontaneously generate rapid online visual predictions to congruent hand orientation cues and do not visually anticipate when presented incongruent cues. We further demonstrate that the speed that these infants generate predictions to congruent motor cues is correlated with their own ability to pre-shape their hands. Finally, we demonstrate that following reaching experience, infants generate rapid predictions to both congruent and incongruent hand shape cues—suggesting that short-term experience changes attention to kinematics.

  5. Cues of maternal condition influence offspring selfishness.

    Directory of Open Access Journals (Sweden)

    Janine W Y Wong

    Full Text Available The evolution of parent-offspring communication was mostly studied from the perspective of parents responding to begging signals conveying information about offspring condition. Parents should respond to begging because of the differential fitness returns obtained from their investment in offspring that differ in condition. For analogous reasons, offspring should adjust their behavior to cues/signals of parental condition: parents that differ in condition pay differential costs of care and, hence, should provide different amounts of food. In this study, we experimentally tested in the European earwig (Forficula auricularia if cues of maternal condition affect offspring behavior in terms of sibling cannibalism. We experimentally manipulated female condition by providing them with different amounts of food, kept nymph condition constant, allowed for nymph exposure to chemical maternal cues over extended time, quantified nymph survival (deaths being due to cannibalism and extracted and analyzed the females' cuticular hydrocarbons (CHC. Nymph survival was significantly affected by chemical cues of maternal condition, and this effect depended on the timing of breeding. Cues of poor maternal condition enhanced nymph survival in early broods, but reduced nymph survival in late broods, and vice versa for cues of good condition. Furthermore, female condition affected the quantitative composition of their CHC profile which in turn predicted nymph survival patterns. Thus, earwig offspring are sensitive to chemical cues of maternal condition and nymphs from early and late broods show opposite reactions to the same chemical cues. Together with former evidence on maternal sensitivities to condition-dependent nymph chemical cues, our study shows context-dependent reciprocal information exchange about condition between earwig mothers and their offspring, potentially mediated by cuticular hydrocarbons.

  7. Towards a Non-Supersymmetric String Phenomenology

    Abel, Steven; Mavroudi, Eirini

    2015-01-01

    Over the past three decades, considerable effort has been devoted to studying the rich and diverse phenomenologies of heterotic strings exhibiting spacetime supersymmetry. Unfortunately, during this same period, there has been relatively little work studying the phenomenologies associated with their non-supersymmetric counterparts. The primary reason for this relative lack of attention is the fact that strings without spacetime supersymmetry are generally unstable, exhibiting large one-loop dilaton tadpoles. In this paper, we demonstrate that this hurdle can be overcome in a class of tachyon-free four-dimensional string models realized through coordinate-dependent compactifications. Moreover, as we shall see, it is possible to construct models in this class whose low-lying states resemble the Standard Model (or even potential unified extensions thereof) --- all without any light superpartners, and indeed without supersymmetry at any energy scale. The existence of such models thus opens the door to general stu...

    Ratcliffe, Philip G

    2014-01-01

    This book deals with the development of particle physics, in particular through the exacting and all-important interplay between theory and experiment, an area that has now become known as phenomenology. Particle physics phenomenology provides the connection between the mathematical models created by theoretical physicists and the experimentalists who explore the building blocks of matter and the forces that operate between them. Assuming no more background knowledge than the basics of quantum mechanics, relativistic mechanics and nuclear physics, the author presents a solid and clear motivation for the developments witnessed by the particle physics community at both high and low energies over that last 50 or 60 years. In particular, the role of symmetries and their violation is central to many of the discussions. Including exercises and many references to original experimental and theoretical papers, as well as other useful sources, it will be essential reading for all students and researchers in ...

  9. Facilitating phenomenological interviewing by means of reflexology

    2005-09-01

    Full Text Available The aim of this article is to show how reflexology could facilitate phenomenological interviewing by probing the lifeworld of individual participants. It presents a hybrid study of phenomenological interviewing and reflexology as a holistic method of health care. In this sense, it is an interparadigmatic study, since it rests on the interface of Western and Oriental thought. This article reports on seven cases which were included in the qualitative, empirical investigation. During the sessions, reflexological readings served as impetus for inquiry into the experiences of the participants, as congestions on reflex points and along meridians were interpreted in terms of physical organs and functions. These readings were related to corresponding emotions as accepted within the reflexology paradigm. It was, however, up to the participants to inform the researcher of events and/or circumstances that caused the emotions. Thus, nonverbal data communicated information that facilitated verbal exchange concerning the life-world of each individual participant.

    2016-09-01

    Techniques for improved characterization of Satellites have been an area of research for several years. Many of these approaches show great promise and have been validated using models and simulations. In this paper, multiple phenomenologies that support satellite characterization will be discussed to include: optical, radar, signals, and Infra-Red. The paper will identify satellite characteristics that could be gleaned from the various data types. Algorithms that support extracting the information will be referenced. Unique collection conditions that enable a phenomenology to yield desired data will be discussed. This paper will discuss the impact of changes to satellite characterization data types over the life of an on-orbit asset. The benefits of such information will be discussed, to include re-acquiring objects after a maneuver.

    1993-01-01

    Reenactment is proposed as an alternative interviewing strategy for phenomenological research. Three techniques borrowed from the psychodramatic method, warming up, scene-setting and soliloquy, are described as they were used in interviews with nurses participating in a study of caregiver/patient relationships. The rationale for and implementation of the techniques are discussed. Indications of successful reenactment during an interview are described and discussed. The data suggest that skillfully directed reenactment can generate intensely vivid recall of memories experiences and emotions, engendering rich descriptions of participants' lived experience and subsequently, produces significant dialogue between interviewer and participant. Parallels are drawn between phenomenological research/philosophy and the philosophy of action upon which psychodramatic techniques are based.

    2012-01-01

    Electroweak and Strong Interaction: Phenomenology, Concepts, Models, begins with relativistic quantum mechanics and some quantum field theory which lay the foundation for the rest of the text. The phenomenology and the physics of the fundamental interactions are emphasized through a detailed discussion of the empirical fundamentals of unified theories of strong, electromagnetic, and weak interactions. The principles of local gauge theories are described both in a heuristic and a geometric framework. The minimal standard model of the fundamental interactions is developed in detail and characteristic applications are worked out. Possible signals of physics beyond that model, notably in the physics of neutrinos are also discussed. Among the applications scattering on nucleons and on nuclei provide salient examples. Numerous exercises with solutions make the text suitable for advanced courses or individual study. This completely updated revised new edition contains an enlarged chapter on quantum chromodynamics an...

  14. Phenomenology of Bilinear Broken R-parity

    CERN Document Server

    Restrepo, D A

    2001-01-01

    The straightforward supersymmetrization of the Standard Model (SM) results in a phenomenologically inconsistent theory in which Baryon number ($B$) and Lepton number ($L$) are violated by dimension 4 operators, inducing fast proton decay. Proton stability allows only for separate $L$ or $B$ violation and, if neutrinos are massive Majorana particles, $L$ violating terms must be present. In this thesis I will study a Supersymmetric Standard Model (SSM) realization with $B$ conservation and minimal $L$ violation. In this framework $L$ is mildly violated only by super-renormalizable terms, allowing for small neutrino Majorana masses. This model is more predictive than the Baryon-Parity SSM. The induced dimension 4 $L$ violating couplings are not arbitrary, and automatically satisfy all experimental constraints. After introducing the theoretical framework for supersymmetric models without Lepton number, I will discuss the phenomenology of the (unstable) lightest neutralino and of the lightest stop. I will show tha...

    2014-01-01

    Searches for multi-Higgs final states allow to constrain parameters of the SM (or extensions thereof) that directly relate to the mechanism of electroweak symmetry breaking. Multi-Higgs production cross sections, however, are small and the phenomenologically accessible final states are challenging to isolate in the busy multi-jet hadron collider environment of the LHC run 2. This makes the necessity to extend the list of potentially observable production mechanisms obvious. Most of the phenomenological analyses in the past have focused on $gg\\to hh+jets$; in this paper we study $pp\\to t\\bar t hh$ at LHC run 2 and find that this channel for $h\\to b\\bar b$ and semi-leptonic and hadronic top decays has the potential to provide an additional handle to constrain the Higgs trilinear coupling in a global fit at the end of run 2.

    The authors define their concept of psychodiagnostic process as inserted within the doctor-patient relationship general context. Five stages are described (a) administering technique, (b) collecting information, (d) writing report, and (e) retrieving information, and termination. Psychodiagnosis is considered under an epistemological criterion. The report is drawn up according to a phenomenological method. This paper ends up with some reflexions about the concepts of health, disease, doctor-patient relationship, and auxiliary means for diagnosis.

    Highlights of recent phenomenological studies of metal failure are given. Failure leading to spallation and fragmentation are typically of interest. The current ‘best model’ includes the following; a full history stress in tension; nucleation initiating dynamic relaxation; toward a tensile yield function; failure dependent on strain, strain rate, and temperature; a mean-preserving ‘macrodefect’ is introduced when failure occurs in tension; and multifield theoretical refinements

    We investigate the minimal theory of massive gravity (MTMG) recently introduced. After reviewing the original construction based on its Hamiltonian in the vielbein formalism, we reformulate it in terms of its Lagrangian in both the vielbein and the metric formalisms. It then becomes obvious that, unlike previous attempts in the literature of Lorentz-violating massive gravity, not only the potential but also the kinetic structure of the action is modified from the de Rham-Gabadadze-Tolley (dRGT) massive gravity theory. We confirm that the number of physical degrees of freedom in MTMG is two at fully nonlinear level. This proves the absence of various possible pathologies such as superluminality, acausality and strong coupling. Afterwards, we discuss the phenomenology of MTMG in the presence of a dust fluid. We find that on a flat homogeneous and isotropic background we have two branches. One of them (self-accelerating branch) naturally leads to acceleration without the genuine cosmological constant or dark energy. For this branch both the scalar and the vector modes behave exactly as in general relativity (GR). The phenomenology of this branch differs from GR in the tensor modes sector, as the tensor modes acquire a non-zero mass. Hence, MTMG serves as a stable nonlinear completion of the self-accelerating cosmological solution found originally in dRGT theory. The other branch (normal branch) has a dynamics which depends on the time-dependent fiducial metric. For the normal branch, the scalar mode sector, even though as in GR only one scalar mode is present (due to the dust fluid), differs from the one in GR, and, in general, structure formation will follow a different phenomenology. The tensor modes will be massive, whereas the vector modes, for both branches, will have the same phenomenology as in GR.

    Supersymmetry (SUSY) stabilizes the hierarchy between the electroweak scale and the scale of grand unified theories (GUT) or the Planck scale. The simplest supersymmetric extension of the SM, the minimal supersymmetric SM (MSSM) solves several phenomenological problems, e. g. the gauge couplings unify and the lightest supersymmetric particle (LSP) is a dark matter candidate. In this thesis, Jarlskog invariants, squark pair production at the LHC and massive neutrinos are discussed in the framework of the MSSM and its extensions. (orig.)

    The "Photochemical Phenomenology Model for the New Millennium" project tackles the issue of reengineering and extension of validated physics-based modeling capabilities ("legacy" computer codes) to application-oriented software for use in science and science-support activities. While the design and architecture layouts are in terms of general particle distributions involved in scattering, impact, and reactive interactions, initial Photochemical Phenomenology Modeling Tool (PPMT) implementations are aimed at construction and evaluation of photochemical transport models with rapid execution for use in remote sensing data analysis activities in distributed systems. Current focus is on the Composite Infrared Spectrometer (CIRS) data acquired during the CASSINI flyby of Jupiter. Overall, the project has stayed on the development track outlined in the Year 1 annual report and most Year 2 goals have been met. The issues that have required the most attention are: implementation of the core photochemistry algorithms; implementation of a functional Java Graphical User Interface; completion of a functional CORBA Component Model framework; and assessment of performance issues. Specific accomplishments and the difficulties encountered are summarized in this report. Work to be carried out in the next year center on: completion of testing of the initial operational implementation; its application to analysis of the CASSINI/CIRS Jovian flyby data; extension of the PPMT to incorporate additional phenomenology algorithms; and delivery of a mature operational implementation.

    Abstract Information received from the visual and chemical senses is qualitatively different. For prey species in aquatic environments, visual cues are spatially and temporally reliable but risky as the prey and predator must often be in close proximity. Chemical cues, by contrast, can be distorted by currents or linger and thus provide less reliable spatial and temporal information, but can be detected from a safe distance. Chemical cues are therefore often the first detected and may provide...

  3. Research approaches related to phenomenology: negotiating a complex landscape.

    Dowling, Maura; Cooney, Adeline

    2012-01-01

    To provide a comprehensive overview of the many research approaches related to phenomenology and their philosophical underpinnings. Phenomenological research approaches are varied and often difficult to apply appropriately. Some researchers persist in labelling their studies as examples of Heideggerian or Husserlian phenomenology without fully understanding the implications of the underpinning philosophical assumptions. Methodological sources related to phenomenology as a philosophy and phenomenology as a research approach are used to illustrate the range of phenomenological methods and their philosophical underpinnings. The origins of phenomenology are the writings of Husserl and the advancement of his thoughts by Merleau-Ponty, Heidegger, Gadamer and Ricoeur. The importance of fully understanding a methodology and its philosophical underpinnings before using it, or claiming to use it, is emphasised. In addition, the variety of phenomenological research approaches that have evolved over the past 50 years are explored and placed in the context of their philosophical underpinnings. There is no single way to conduct a phenomenological study. There are many approaches from which researchers can choose. This has resulted in a range of labels and often in different descriptions for the same approach. It is essential that researchers planning to use phenomenology are familiar with the many approaches available. This knowledge will help researchers choose the approaches that best suit the aims of their studies.

  4. Medicine and the individual: is phenomenology the answer?

    Gergel, Tania L

    2012-10-01

    The issue of how to incorporate the individual's first-hand experience of illness into broader medical understanding is a major question in medical theory and practice. In a philosophical context, phenomenology, with its emphasis on the subject's perception of phenomena as the basis for knowledge and its questioning of naturalism, seems an obvious candidate for addressing these issues. This is a review of current phenomenological approaches to medicine, looking at what has motivated this philosophical approach, the main problems it faces and suggesting how it might become a useful philosophical tool within medicine, with its own individual, but interrelated, contribution to make to current medical debates. After the general background, there is a brief summary of phenomenological ideas and their current usage in a medical context. Next is a critique of four key claims within current phenomenological medical works, concerning both the role phenomenology plays and the supposedly clear divide between phenomenology and other approaches. There are significant problems within these claims, largely because they overlook the complexity of the questions they consider. Finally, there is some more in-depth examination of phenomenology itself and the true complexity of phenomenological debate concerning subjectivity. The aim is to show that it will be both more productive and truer to phenomenology itself, if we use phenomenology as a philosophical method for explicating and gaining deeper understanding of complex and fundamental problems, which are central to medicine, rather than as providing simple, but flawed solutions.

    Relapse is a widely recognized and difficult to treat feature of the addictions. Substantial evidence implicates cue-triggered activation of the mesolimbic dopamine system as an important contributing factor. Even drug cues presented outside of conscious awareness (i.e., subliminally) produce robust activation within this circuitry, indicating the sensitivity and vulnerability of the brain to potentially problematic reward signals. Because pharmacological agents that prevent these early cue-induced responses could play an important role in relapse prevention, we examined whether baclofen-a GABAB receptor agonist that reduces mesolimbic dopamine release and conditioned drug responses in laboratory animals-could inhibit mesolimbic activation elicited by subliminal cocaine cues in cocaine-dependent individuals. Twenty cocaine-dependent participants were randomized to receive baclofen (60 mg/d; 20 mg t.i.d.) or placebo. Event-related BOLD fMRI and a backward-masking paradigm were used to examine the effects of baclofen on subliminal cocaine (vs neutral) cues. Sexual and aversive cues were included to examine specificity. We observed that baclofen-treated participants displayed significantly less activation in response to subliminal cocaine (vs neutral) cues, but not sexual or aversive (vs neutral) cues, than placebo-treated participants in a large interconnected bilateral cluster spanning the ventral striatum, ventral pallidum, amygdala, midbrain, and orbitofrontal cortex (voxel threshold p baclofen may inhibit the earliest type of drug cue-induced motivational processing-that which occurs outside of awareness-before it evolves into a less manageable state.

    There is evidence that women may be less successful when attempting to quit smoking than men. One potential contributory cause of this gender difference is differential craving and stress reactivity to smoking- and negative affect/stress-related cues. The present human laboratory study investigated the effects of gender on reactivity to smoking and negative affect/stress cues by exposing nicotine dependent women (n = 37) and men (n = 53) smokers to two active cue types, each with an associated control cue: (1) in vivo smoking cues and in vivo neutral control cues, and (2) imagery-based negative affect/stress script and a neutral/relaxing control script. Both before and after each cue/script, participants provided subjective reports of smoking-related craving and affective reactions. Heart rate (HR) and skin conductance (SC) responses were also measured. Results indicated that participants reported greater craving and SC in response to smoking versus neutral cues and greater subjective stress in response to the negative affect/stress versus neutral/relaxing script. With respect to gender differences, women evidenced greater craving, stress and arousal ratings and lower valence ratings (greater negative emotion) in response to the negative affect/stressful script. While there were no gender differences in responses to smoking cues, women trended towards higher arousal ratings. Implications of the findings for treatment and tobacco-related morbidity and mortality are discussed.

  7. Perception of health from facial cues

    2016-01-01

    Impressions of health are integral to social interactions, yet poorly understood. A review of the literature reveals multiple facial characteristics that potentially act as cues to health judgements. The cues vary in their stability across time: structural shape cues including symmetry and sexual dimorphism alter slowly across the lifespan and have been found to have weak links to actual health, but show inconsistent effects on perceived health. Facial adiposity changes over a medium time course and is associated with both perceived and actual health. Skin colour alters over a short time and has strong effects on perceived health, yet links to health outcomes have barely been evaluated. Reviewing suggested an additional influence of demeanour as a perceptual cue to health. We, therefore, investigated the association of health judgements with multiple facial cues measured objectively from two-dimensional and three-dimensional facial images. We found evidence for independent contributions of face shape and skin colour cues to perceived health. Our empirical findings: (i) reinforce the role of skin yellowness; (ii) demonstrate the utility of global face shape measures of adiposity; and (iii) emphasize the role of affect in facial images with nominally neutral expression in impressions of health.

    Why is it so difficult to resist the desire to use social media? One possibility is that frequent social media users possess strong and spontaneous hedonic reactions to social media cues, which, in turn, makes it difficult to resist social media temptations. In two studies (total N = 200), we investigated less-frequent and frequent social media users' spontaneous hedonic reactions to social media cues using the Affect Misattribution Procedure-an implicit measure of affective reactions. Results demonstrated that frequent social media users showed more favorable affective reactions in response to social media (vs. control) cues, whereas less-frequent social media users' affective reactions did not differ between social media and control cues (Studies 1 and 2). Moreover, the spontaneous hedonic reactions to social media (vs. control) cues were related to self-reported cravings to use social media and partially accounted for the link between social media use and social media cravings (Study 2). These findings suggest that frequent social media users' spontaneous hedonic reactions in response to social media cues might contribute to their difficulties in resisting desires to use social media.

  12. The effects of macro-level interventions on addictive behavior.

    Science.gov (United States)

    Pacula, R L; Chaloupka, F J

    2001-12-01

    Drug addictions are often viewed as compulsive behaviors, not sensitive to the typical rules of self-discipline or market forces. Nonetheless, many governments try to discourage consumption of addictive substances through macro policy tools, such as taxation, regulation and prohibition, in an effort to reduce the harmful consequences that result from their consumption. The government's ability to discourage this type of behavior through these macro policies depends critically on the responsiveness of addictive consumption to market interventions. This paper reviews the growing literature that applies economic principles to the analysis of "substance abuse." Specifically, we review the impact of prices and public policies on the demands for tobacco, alcohol, and illicit drugs. The findings from these studies clearly demonstrate that even addictive behaviors are sensitive to changes in the price of substances being abused. When the full price of the addictive good rises, consumption of that good falls, even among abusers. Therefore, public policies that raise the full price of a drug to a consumer, particularly youth, are likely to result in long run reductions in rates of addiction.

    Two hundred and seventy patients with schizophrenia (104 patients in Kelantan and 166 patients in Penang) were interviewed using the Present State Examination to elicit the differences in the phenomenology of their hallucinations. The results indicate that there are significant differences in the phenomenology of hallucinations between the Malays of Penang and Kelantan and also among some Chinese patients. These findings indicate that culture does affect the phenomenology of schizophrenia, even among people of the same race but of different regions.

    2016-01-01

    I discuss the role of quantum effects in the phenomenology of effective supergravity theories from compactification of the weakly coupled heterotic string. An accurate incorporation of these effects requires a regularization procedure that respects local supersymmetry and BRST invariance and that retains information associated with the cut-off scale, which has physical meaning in an effective theory. I briefly outline the Pauli-Villars regularization procedure, describe some applications, and comment on what remains to be done to fully define the effective quantum field theory.

    2008-12-01

    Full Text Available In this paper I will examine Husserl’s attempt to establish a ground for science with the so called transcendental reduction. This will entail both an identification of the problems that Husserl was attempting to solve as well as a careful analysis of Husserl’s account of his methodology. I will then examine how Derrida’s reading, which affirms the phenomenological project in many of its essential aspects, begins to signal a subtle yet ultimately radical disagreement. This disagreement will have lasting implications for our understanding of the possibilities designated by the transcendental method in Husserl’s thinking.

    Full Text Available Although manga constitute a massive transcultural flow, they are extremely diverse as far as genre and content are concerned. This article attempts to bridge these differences by highlighting phenomenological patterns within popular manga: by bracketing content, the author focuses on the experience of reading manga, thereby considering the medial aspect of these works. By examining a diverse corpus of contemporary popular series (Bleach, Death Note, Fruits Basket, and Kitchen Princess, the article pays attention to elements such as reading rhythm, contrast, fragmentation, and page tabularity, in order to pave the way for future study of manga’s place in the contemporary medial ethos.

    Finite Unified Theories (FUTs) are N = 1 supersymmetric Grand Unified Theories (GUTs) which can be made finite to all-loop orders, leading to a large reduction in the number of free parameters. We confront the predictions of SU(5) FUTs with the top and bottom quark masses, which allows us to discriminate among different models. We include further low-energy phenomenology constraints, such as B physics observables, the bound on the SM Higgs mass and the cold dark matter density, and then are able to make predictions for the lightest Higgs boson mass and the sparticle spectrum.

  4. Phenomenology of chiral damping in noncentrosymmetric magnets

    KAUST Repository

    Akosa, Collins Ashu

    2016-06-21

    A phenomenology of magnetic chiral damping is proposed in the context of magnetic materials lacking inversion symmetry. We show that the magnetic damping tensor acquires a component linear in magnetization gradient in the form of Lifshitz invariants. We propose different microscopic mechanisms that can produce such a damping in ferromagnetic metals, among which local spin pumping in the presence of an anomalous Hall effect and an effective “s-d” Dzyaloshinskii-Moriya antisymmetric exchange. The implication of this chiral damping in terms of domain-wall motion is investigated in the flow and creep regimes.

  5. Subjectivity and intersubjectivity between semiotics and phenomenology

    Directory of Open Access Journals (Sweden)

    Francesco Marsciani

    2014-12-01

    Full Text Available A semiotic theory of subjectivity cannot prescind from a radical consideration of the intersubjective dimension, which, from the phenomenological perspective, represents the constitutive instance of the meaning of the world. The theory of signification has yet to come to terms with this fundamental option: the theory of enunciation, for example, is still tied to the alternative between an egological perception of the production of meaning and a truly intersubjective conception. A radically intersubjective understanding of the constitution of meaning must, in the theory of enunciation, include an authentic theory of alterity in which the production of communicative intentions can be described based on a more fundamental transcendental intentionality.

    Behavioural addictions are characterized by an inability to resist an urge or drive resulting in actions that are harmful to oneself or others. Behavioural addictions share characteristics with substance and alcohol abuse, and in areas such as natural history, phenomenology, and adverse consequences. Behavioural addictions include pathological gambling, kleptomania, pyromania, compulsive buying, compulsive sexual behaviour, Internet addiction, and binge eating disorder. Few studies have examined the efficacy of pharmacological and psychological treatment for the various behavioural addictions, and therefore, currently, no treatment recommendations can be made.

    Full Text Available Reconsideration of psychopathology arises from a phenomenological perspective focused on the case of third-generation therapies. Basic principles and bases of the therapeutic actions of functional analytic psychotherapy are described. A way of understanding the psychopathology that encompasses both a transverse diagnosis related to dysfunctional avoidance of psychological events as a theory of pathological formation of Self is presented. Both functional formats of psychopathological explanation would account for multiple clinical diagnoses commonly used. Finally we conclude about the differences and conceptual difficulties between different generations of cognitive-behavioral therapies.

    CERN Document Server

    Olmo, Gonzalo J

    2011-01-01

    We show that a quadratic gravitational Lagrangian in the Palatini formulation is able to capture different aspects of quantum gravity phenomenology in a single framework. In particular, we show that in this theory field excitations propagating with different energy-densities perceive different background metrics, which is a fundamental characteristic of the DSR and Rainbow Gravity approaches. Also, the resulting isotropic and anisotropic cosmologies are free from the big bang singularity. This singularity avoidance occurs non-perturbatively and shares some similitudes with the effective dynamics of loop quantum cosmology.

Nevertheless, the blurriness of emotive and physical reactions to the world can be said to be due not to their impreciseness but rather to their richness in nuance...... with the intellect but also with the senses. We propose an approach to both the making and communication of knowledge, which could be called post-hermeneutic –a phenomenology not aiming at fixation of identified significance, but at a knowing that includes and even takes advantage of the fluctuating and manifold...

  14. The semantic representation of event information depends on the cue modality: an instance of meaning-based retrieval.

    Science.gov (United States)

    Karlsson, Kristina; Sikström, Sverker; Willander, Johan

    2013-01-01

    The semantic content, or the meaning, is the essence of autobiographical memories. In comparison to previous research, which has mainly focused on the phenomenological experience and the age distribution of retrieved events, the present study provides a novel view on the retrieval of event information by quantifying the information as semantic representations. We investigated the semantic representation of sensory cued autobiographical events and studied the modality hierarchy within the multimodal retrieval cues. The experiment comprised a cued recall task, where the participants were presented with visual, auditory, olfactory or multimodal retrieval cues and asked to recall autobiographical events. The results indicated that the three different unimodal retrieval cues generate significantly different semantic representations. Further, the auditory and the visual modalities contributed the most to the semantic representation of the multimodally retrieved events. Finally, the semantic representation of the multimodal condition could be described as a combination of the three unimodal conditions. In conclusion, these results suggest that the meaning of the retrieved event information depends on the modality of the retrieval cues.

  15. The problem of psychopathology and phenomenology. What is viable and not viable in phenomenological psychiatry.

    Science.gov (United States)

    Ramos-Gorostiza, Pablo; Adán-Manes, Jaime

    2013-01-01

    The epistemological underpinnings of psychiatric theory and practice have always been unstable. This reflects the essential contradiction existing between the task (the description and individuation of speech and behavior as psychopathological symptoms) and tools (semiotics). As a result of this contradiction, the history of psychiatry is one of permanent crisis in which there are moments of temporary stability as approaches that aim at organizing this mismatch between tasks and tools gain prevalence. However, these approaches can only offer a false sense of unity, consistency and progress. In this sense, a narrow perspective on a particular period may lead us to believe that psychiatry is just another medical specialty with its own specific theoretical framework like others. However, any such perspective overlooks the coexistence of different schools, disagreements, contradictions, global alternatives, etc. For a certain period of time, phenomenology was assumed to be as the solution for psychiatry’s internal contradiction. As we see it, phenomenology was only partially understood. Despite the great influence it exerted upon psychiatry worldwide, it finally fell into disuse as a mere empiricism. Husserl’s phenomenology was more thoroughly understood and better assimilated by other psychiatrists, and its influence has persisted to the present day. If we view phenomenology in its proper (Husserlian) sense, it is possible to understand psychopathology as a means of creating intelligibility and clarifying the uniqueness of psychiatry. On the other hand, if phenomenology is understood as a representational theory, it will eventually lead to an unavoidable relapse into psychologism, which has been the main path of psychiatry until now.

  16. Deciphering faces: quantifiable visual cues to weight.

    Coetzee, Vinet; Chen, Jingying; Perrett, David I; Stephen, Ian D

    2010-01-01

    Body weight plays a crucial role in mate choice, as weight is related to both attractiveness and health. People are quite accurate at judging weight in faces, but the cues used to make these judgments have not been defined. This study consisted of two parts. First, we wanted to identify quantifiable facial cues that are related to body weight, as defined by body mass index (BMI). Second, we wanted to test whether people use these cues to judge weight. In study 1, we recruited two groups of Caucasian and two groups of African participants, determined their BMI and measured their 2-D facial images for: width-to-height ratio, perimeter-to-area ratio, and cheek-to-jaw-width ratio. All three measures were significantly related to BMI in males, while the width-to-height and cheek-to-jaw-width ratios were significantly related to BMI in females. In study 2, these images were rated for perceived weight by Caucasian observers. We showed that these observers use all three cues to judge weight in African and Caucasian faces of both sexes. These three facial cues, width-to-height ratio, perimeter-to-area ratio, and cheek-to-jaw-width ratio, are therefore not only related to actual weight but provide a basis for perceptual attributes as well.

  17. Enhancing Manual Scan Registration Using Audio Cues

    Science.gov (United States)

    Ntsoko, T.; Sithole, G.

    2014-04-01

    Indoor mapping and modelling requires that acquired data be processed by editing, fusing, formatting the data, amongst other operations. Currently the manual interaction the user has with the point cloud (data) while processing it is visual. Visual interaction does have limitations, however. One way of dealing with these limitations is to augment audio in point cloud processing. Audio augmentation entails associating points of interest in the point cloud with audio objects. In coarse scan registration, reverberation, intensity and frequency audio cues were exploited to help the user estimate depth and occupancy of space of points of interest. Depth estimations were made reliably well when intensity and frequency were both used as depth cues. Coarse changes of depth could be estimated in this manner. The depth between surfaces can therefore be estimated with the aid of the audio objects. Sound reflections of an audio object provided reliable information of the object surroundings in some instances. For a point/area of interest in the point cloud, these reflections can be used to determine the unseen events around that point/area of interest. Other processing techniques could benefit from this while other information is estimated using other audio cues like binaural cues and Head Related Transfer Functions. These other cues could be used in position estimations of audio objects to aid in problems such as indoor navigation problems.

  18. Biophysical Cueing and Vascular Endothelial Cell Behavior

    Directory of Open Access Journals (Sweden)

    Joshua A. Wood

    2010-03-01

    Full Text Available Human vascular endothelial cells (VEC line the vessels of the body and are critical for the maintenance of vessel integrity and trafficking of biochemical cues. They are fundamental structural elements and are central to the signaling environment. Alterations in the normal functioning of the VEC population are associated with a number of vascular disorders among which are some of the leading causes of death in both the United States and abroad. VECs attach to their underlying stromal elements through a specialization of the extracellular matrix, the basement membrane. The basement membrane provides signaling cues to the VEC through its chemical constituents, by serving as a reservoir for cytoactive factors and through its intrinsic biophysical properties. This specialized matrix is composed of a topographically rich 3D felt-like network of fibers and pores on the nano (1–100 nm and submicron (100–1,000 nm size scale. The basement membrane provides biophysical cues to the overlying VECs through its intrinsic topography as well as through its local compliance (relative stiffness. These biophysical cues modulate VEC adhesion, migration, proliferation, differentiation, and the cytoskeletal signaling network of the individual cells. This review focuses on the impact of biophysical cues on VEC behaviors and demonstrates the need for their consideration in future vascular studies and the design of improved prosthetics.

  19. Word segmentation with universal prosodic cues.

    Science.gov (United States)

    Endress, Ansgar D; Hauser, Marc D

    2010-09-01

    When listening to speech from one's native language, words seem to be well separated from one another, like beads on a string. When listening to a foreign language, in contrast, words seem almost impossible to extract, as if there was only one bead on the same string. This contrast reveals that there are language-specific cues to segmentation. The puzzle, however, is that infants must be endowed with a language-independent mechanism for segmentation, as they ultimately solve the segmentation problem for any native language. Here, we approach the acquisition problem by asking whether there are language-independent cues to segmentation that might be available to even adult learners who have already acquired a native language. We show that adult learners recognize words in connected speech when only prosodic cues to word-boundaries are given from languages unfamiliar to the participants. In both artificial and natural speech, adult English speakers, with no prior exposure to the test languages, readily recognized words in natural languages with critically different prosodic patterns, including French, Turkish and Hungarian. We suggest that, even though languages differ in their sound structures, they carry universal prosodic characteristics. Further, these language-invariant prosodic cues provide a universally accessible mechanism for finding words in connected speech. These cues may enable infants to start acquiring words in any language even before they are fine-tuned to the sound structure of their native language.

  20. Personality disorders from a phenomenological perspective.

    Science.gov (United States)

    Dörr Zengers, O

    2008-01-01

    Different studies have questioned the capacity of the categorical diagnostics to establish a clear distinction between the existence or not of a determined personality disorder. The dimensional perspective would approach more to reality, in the measure that it tries to measure the different intensity degrees in which these disorders are present in the patients. But its application is very laborious and besides, presupposes that those categories whose nuances it pretends to measure really exist. The foresaid leads us to appeal to phenomenological perspective, which seems to be more adequate for the study of complex realities, as it is the case of the personality and its disorders. The essential features of the phenomenological method in the sense of Husserl are described, as well as his contribution to the study of personality disorders. This can be summarized in three fundamental points: the ideal types, introduced in psychiatry by Karl Jaspers, the existential types, by Ludwig Binswanger, and the dialectic typologies and polarities, by Wolfgang Blankenburg and the undersigned. This author defines and develops each one of these concepts, aiming to show their advantages with respect to the categorical and dimensional systems.

  1. Hermann Weyl's Phenomenological Contribution to Quantum Physics

    Science.gov (United States)

    Mastrobisi, Giorgio J.

    On examining carefully Weyl's writings one realizes that the great mathematician from Göttingen in his researches follows the programmatic scheme of the binomial of "wissenschaftliche Erkenntnis" (scientific Knowledge) and "philosophische Besinnung" (philosophical Reflection). In 1954 in a retrospective writing he affirmed: «The formulation of Einstein's Theory of Relativity and the Laws of Gravitation, valid in this context and corroborated by experimental proofs turning to experience, constitute a method which combines "Wesenanalyse" with "mathematische Konstruktion" of convincing and excellent exemplarity». This conviction has conducted him to a close collaboration with A. Einstein (documented by punctual correspondence) for the decisive formulation of the "General Theory of Relativity", but also of the Theory of unified Field of Gravitation and Electromagnetism and therefore the following formulation of some fundamental principles of Quantum Physics. So Weyl's theoretical formation was marked by the devotion toward a mathematical formalization ("mathematische Konstruktion") of physical phenomena, reporting each of them to the causal structure of the "mathematical thinking" and geometry, contemporarely to a strong inclination toward the phenomenological "Analysis of essence". He brings really a notable quantity of considerations in that 1954 essay by the point of view of the decisive role that the "pure Phenomenology" of Edmund Husserl developed in the determination of his scientific activity.

    2000-09-01

    The authors examined the phenomenology of bibliotherapy and its effects in changing preservice teachers' punitive attitudes toward children. Participants (N = 29) were enrolled in a university course (Introduction to Emotional Disturbance). Five books by Torey Hayden, autobiographical accounts of teaching and building relationships with students with emotional and behavioral disorders, were read and discussed within the framework of group bibliotherapy. Participants completed a self-report rating form measuring their tendency toward punitiveness during the first and last weeks of the 15-week semester. Participants also completed a questionnaire measuring the bibliotherapeutic impact of reading Hayden's texts, and they kept journals about the experience of reading Hayden. Comparison of the group's pre- and post-measures on punitiveness showed a small, albeit significant decrease in punitiveness; decreased punitiveness was associated with the therapeutic impact of reading Hayden. Phenomenological analysis of the participants' journal entries revealed that the structure of the experience of reading Hayden was one of identification with the protagonist, leading to emotional and cognitive learning.

  3. Aspects Of Grand Unified And String Phenomenology

    Walker, J W

    2005-01-01

    Explored in this report is the essential interconnectedness of Grand Unified and String Theoretic Phenomenology. In order to extract a modeled connection to low-energy physics from the context of superstring theory, it is presently necessary to input some preferred region of parameter space in which to search. This need may be well filled by a parallel study of Grand Unification, which is by contrast in immediate proximity to a wealth of experimental data. The favored GUT so isolated may then reasonably transfer this phenomenological correlation to a string embedding, receiving back by way of trade a greater sense of primary motivation, and potentially enhanced predictability for parameters taken as input in a particle physics context. The Flipped SU(5) GUT will be our preferred framework in which to operate and first receives an extended study in a non-string derived setting. Of particularly timely interest are predictions for super-particle mass ranges and the interrelated question of proton decay lifetime....

    In the context of phenomenological models in which the soft supersymmetry-breaking parameters of the MSSM become universal at some unification scale, M_{in}, above the GUT scale, \\mgut, it is possible that all the scalar mass parameters m_0, the trilinear couplings A_0 and the bilinear Higgs coupling B_0 vanish simultaneously, as in no-scale supergravity. Using these no-scale inputs in a renormalization-group analysis of the minimal supersymmetric SU(5) GUT model, we pay careful attention to the matching of parameters at the GUT scale. We delineate the region of M_{in}, m_{1/2} and \\tan \\beta where the resurrection of no-scale supergravity is possible, taking due account of the relevant phenomenological constraints such as electroweak symmetry breaking, m_h, b \\to s \\gamma, the neutralino cold dark matter density \\ohsq and g_\\mu - 2. No-scale supergravity survives in an L-shaped strip of parameter space, with one side having with one side having m_{1/2} \\gappeq 200 {\\rm GeV}, the second (orthogonal) side havi...

  5. Beyond Empathy. Phenomenological Approaches to Intersubjectivity

    Directory of Open Access Journals (Sweden)

    Dan Zahavi

    2011-02-01

    Full Text Available Drawing on the work of Scheler, Heidegger, Merleau-Ponty, Husserl and Sartre, this article presents an overview of some of the diverse approaches to intersubjectivity that can be found in the phenomenological tradition. Starting with a brief description of Scheler’s criticism of the argument from analogy, the article continues by showing that the phenomenological analyses of intersubjectivity involve much more than a ‘solution’ to the ‘traditional’ problem of other minds. Intersubjectivity doesn’t merely concern concrete faceto-face encounters between individuals. It is also something that is at play in simple perception, in tool-use, in emotions, drives and different types of self-awareness. Ultimately, the phenomenologists would argue that a treatment of intersubjectivity requires a simultaneous analysis of the relationship between subjectivity and world. It is not possible simply to insert intersubjectivity somewhere within an already established ontology; rather, the three regions ‘self’, ‘others’, and ‘world’ belong together; they reciprocally illuminate one another, and can only be understood in their interconnection. 

  6. Defocus cue and saliency preserving video compression

    2016-11-01

    There are monocular depth cues present in images or videos that aid in depth perception in two-dimensional images or videos. Our objective is to preserve the defocus depth cue present in the videos along with the salient regions during compression application. A method is provided for opportunistic bit allocation during the video compression using visual saliency information comprising both the image features, such as color and contrast, and the defocus-based depth cue. The method is divided into two steps: saliency computation followed by compression. A nonlinear method is used to combine pure and defocus saliency maps to form the final saliency map. Then quantization values are assigned on the basis of these saliency values over a frame. The experimental results show that the proposed scheme yields good results over standard H.264 compression as well as pure and defocus saliency methods.

  8. Perceptions of Sexual Orientation From Minimal Cues.

    Rule, Nicholas O

    2017-01-01

    People derive considerable amounts of information about each other from minimal nonverbal cues. Apart from characteristics typically regarded as obvious when encountering another person (e.g., age, race, and sex), perceivers can identify many other qualities about a person that are typically rather subtle. One such feature is sexual orientation. Here, I review the literature documenting the accurate perception of sexual orientation from nonverbal cues related to one's adornment, acoustics, actions, and appearance. In addition to chronicling studies that have demonstrated how people express and extract sexual orientation in each of these domains, I discuss some of the basic cognitive and perceptual processes that support these judgments, including how cues to sexual orientation manifest in behavioral (e.g., clothing choices) and structural (e.g., facial morphology) signals. Finally, I attend to boundary conditions in the accurate perception of sexual orientation, such as the states, traits, and group memberships that moderate individuals' ability to reliably decipher others' sexual orientation.

    attention was measured by means of eye-tracking. Task (free viewing, product healthfulness evaluation, and purchase likelihood evaluation) and product (five different yoghurt products) were varied in a mixed within-between subjects design. The free viewing condition served as a baseline against which...... increases or decreases in attention during product healthfulness evaluation and purchase likelihood evaluation were assessed. The analysis revealed that the only element operating as a health cue during product healthfulness evaluation was the nutrition label. The information cues used during purchase...... likelihood evaluation were the name of the product category and the nutrition label. Taken together, the results suggest that the only information element that consumers consistently utilize as a health cue is the nutrition label and that only a limited amount of attention is devoted to read nutrition labels...

  10. Coordinated sensor cueing for chemical plume detection

    Abraham, Nathan J.; Jensenius, Andrea M.; Watkins, Adam S.; Hawthorne, R. Chad; Stepnitz, Brian J.

    2011-05-01

    This paper describes an organic data fusion and sensor cueing approach for Chemical, Biological, Radiological, and Nuclear (CBRN) sensors. The Joint Warning and Reporting Network (JWARN) uses a hardware component referred to as the JWARN Component Interface Device (JCID). The Edgewood Chemical and Biological Center has developed a small footprint and open architecture solution for the JCID capability called JCID-on-a-Chip (JoaC). The JoaC program aims to reduce the cost and complexity of the JCID by shrinking the necessary functionality down to a small single board computer. This effort focused on development of a fusion and cueing algorithm organic to the JoaC hardware. By embedding this capability in the JoaC, sensors have the ability to receive and process cues from other sensors without the use of a complex and costly centralized infrastructure. Additionally, the JoaC software is hardware agnostic, as evidenced by its drop-in inclusion in two different system-on-a-chip platforms including Windows CE and LINUX environments. In this effort, a partnership between JPM-CA, JHU/APL, and the Edgewood Chemical and Biological Center (ECBC), the authors implemented and demonstrated a new algorithm for cooperative detection and localization of a chemical agent plume. This experiment used a pair of mobile Joint Services Lightweight Standoff Chemical Agent Detector (JSLSCAD) units which were controlled by fusion and cueing algorithms hosted on a JoaC. The algorithms embedded in the JoaC enabled the two sensor systems to perform cross cueing and cooperatively form a higher fidelity estimate of chemical releases by combining sensor readings. Additionally, each JSLSCAD had the ability to focus its search on smaller regions than those required by a single sensor system by using the cross cue information from the other sensor.

  19. Cognitive Cues are More Compelling than Facial Cues in Determining Adults' Reactions towards Young Children

    Directory of Open Access Journals (Sweden)

    Carlos Hernández Blasi

    2015-04-01

    Full Text Available Previous research has demonstrated the significant influence that both children's facial features (Lorenz, 1943 and children's cognitive expressions (Bjorklund, Hernández Blasi, and Periss, 2010 have on adults' perception of young children. However, until now, these two types of cues have been studied independently. The present study contrasted these two types of cues simultaneously in a group of college students. To this purpose, we designed five experimental conditions (Consistent, Inconsistent, Mature-Face, Immature-Face, and Faces-Only in which we varied the presentation of a series of mature and immature vignettes (including two previously studied types of thinking: natural thinking and supernatural thinking associated with a series of more mature and less mature children's faces. Performance in these conditions was contrasted with data from a Vignettes-Only condition taken from Bjorklund et al. (2010. Results indicated that cognitive cues were more powerful than facial cues in determining adults' perceptions of young children. From an evolutionary developmental perspective, we suggest that facial cues are more relevant to adults during infancy than during the preschool period, when, with the development of spoken language, the verbalized expressions of children's thoughts become the principal cues influencing adults' perceptions, with facial cues playing a more secondary role.

  20. Vowel identification by cochlear implant users: Contributions of duration cues and dynamic spectral cues.

    Science.gov (United States)

    Donaldson, Gail S; Rogers, Catherine L; Johnson, Lindsay B; Oh, Soo Hee

    2015-07-01

    A recent study from our laboratory assessed vowel identification in cochlear implant (CI) users, using full /dVd/ syllables and partial (center- and edges-only) syllables with duration cues neutralized [Donaldson, Rogers, Cardenas, Russell, and Hanna (2013). J. Acoust. Soc. Am. 134, 3021-3028]. CI users' poorer performance for partial syllables as compared to full syllables, and for edges-only syllables as compared to center-only syllables, led to the hypotheses (1) that CI users may rely strongly on vowel duration cues; and (2) that CI users have more limited access to dynamic spectral cues than steady-state spectral cues. The present study tested those hypotheses. Ten CI users and ten young normal hearing (YNH) listeners heard full /dVd/ syllables and modified (center- and edges-only) syllables in which vowel duration cues were either preserved or eliminated. The presence of duration cues significantly improved vowel identification scores in four CI users, suggesting a strong reliance on duration cues. Duration effects were absent for the other CI users and the YNH listeners. On average, CI users and YNH listeners demonstrated similar performance for center-only stimuli and edges-only stimuli having the same total duration of vowel information. However, three CI users demonstrated significantly poorer performance for the edges-only stimuli, indicating apparent deficits of dynamic spectral processing.

  2. Some reflections on clinical supervision: an existential-phenomenological paradigm.

    Science.gov (United States)

    Jones, A

    1998-03-01

    This paper reviews psychotherapy, counselling, and nursing literature related to ideas of clinical supervision and attempts to illuminate areas important to effective health related practice and specifically palliative care. Included are explorations of existentialism, phenomenology, existential phenomenology and psychoanalytical concepts. The phenomenological idea of lived experience is outlined and the Heideggerian notion of authenticity is explored in context. The paper also examines dynamic forces such as hope, trust and personal values that might influence clinical supervision design and so inform a framework for practice. An existential-phenomenological method of supervision is offered as one basis for professional practice. The central recommendation of this paper is, however, to identify relevant value and belief systems to direct clinical supervision. Nursing models might appropriately instruct approaches to supervision. The writer considers the phenomenological idea of the lived experiences as a means by which to at once capture the essence of palliative care nursing and guide the supervision towards the existential idea of authenticity.

  3. Phenomenological Justification of Theory of Time

    Directory of Open Access Journals (Sweden)

    Perminov V. Ya.

    2013-01-01

    Full Text Available The article exposes Husserl’s theory of time and provides its detailed comparison with theories of time of I. Kant and F. Brentano. The author first examines the general principles of the phenomenological theory of consciousness, and then analyzes the time concept of F. Brentano and Husserl’s criticism of these ideas, and eventually makes a comparison of Husserl’s and Kant’s theories of time. The author is inclined to conclude that progress in the interpretation of the time made by Husserl, is largely external, based on unacceptable epistemological principles. Critique of these principles the author plans to carry out in one of the next issues of the magazine.

    Rattazzi, Riccardo; Wells, J D; Rattazzi, Riccardo; Strumia, Alessandro; Wells, James D.

    2000-01-01

    We explore the phenomenology of a class of models with anomaly-mediated supersymmetry breaking. These models retain the successful flavor properties of the minimal scenario while avoiding the tachyons. The mass spectrum is predicted in terms of a few parameters. However various qualitatively different spectra are possible, often strongly different from the ones usually employed to explore capabilities of new accelerators. One stable feature is the limited spread of the spectrum, so that squarks and gluinos could be conceivably produced at TEVII. The lightest superpartner of standard particles is often a charged slepton or a neutral higgsino. It behaves as a stable particle in collider experiments but it decays at or before nucleosynthesis. We identify the experimental signatures at hadron colliders that can help distinguish this scenario from the usual ones.

  5. The Phenomenology of Small-Scale Turbulence

    Sreenivasan, K. R.; Antonia, R. A.

    I have sometimes thought that what makes a man's work classic is often just this multiplicity [of interpretations], which invites and at the same time resists our craving for a clear understanding. Wright (1982, p. 34), on Wittgenstein's philosophy Small-scale turbulence has been an area of especially active research in the recent past, and several useful research directions have been pursued. Here, we selectively review this work. The emphasis is on scaling phenomenology and kinematics of small-scale structure. After providing a brief introduction to the classical notions of universality due to Kolmogorov and others, we survey the existing work on intermittency, refined similarity hypotheses, anomalous scaling exponents, derivative statistics, intermittency models, and the structure and kinematics of small-scale structure - the latter aspect coming largely from the direct numerical simulation of homogeneous turbulence in a periodic box.

    Svantesson, Patrik; Hall, Jonathan P; King, Stephen F

    2012-01-01

    The E6SSM is a promising model based on the group E6, assumed to be broken at the GUT scale, leading to the group SU(3)\\times SU(2)\\times U(1)\\times U(1)' at the TeV scale. It gives a solution to the MSSM {\\mu}-problem without introducing massless axions, gauge anomalies or cosmological domain walls. The model contains three families of complete 27s of E6, giving a richer phenomenology than the MSSM. The E6SSM generically predicts gluino cascade decay chains which are about 2 steps longer than the MSSM's due to the presence of several light neutralino states. This implies less missing (and more visible) transverse momentum in collider experiments and kinematical distributions such as M_eff are different. Scans of parameter space and MC analysis suggest that current SUSY search strategies and exclusion limits have to be reconsidered.

  7. Phenomenology of muon-induced neutron yield

    Science.gov (United States)

    Malgin, A. S.

    2017-07-01

    The cosmogenic neutron yield Yn characterizes the ability of matter to produce neutrons under the effect of cosmic ray muons with spectrum and average energy corresponding to an observation depth. The yield is the basic characteristic of cosmogenic neutrons. The neutron production rate and neutron flux both are derivatives of the yield. The constancy of the exponents α and β in the known dependencies of the yield on energy Yn∝Eμα and the atomic weight Yn∝Aβ allows one to combine these dependencies in a single formula and to connect the yield with muon energy loss in matter. As a result, the phenomenological formulas for the yields of muon-induced charged pions and neutrons can be obtained. These expressions both are associated with nuclear loss of the ultrarelativistic muons, which provides the main contribution to the total neutron yield. The total yield can be described by a universal formula, which is the best fit of the experimental data.

  8. [Phenomenology of multiculturalism and intercultural pluralism].

    Science.gov (United States)

    2012-01-01

    Multiculturalism is defined as the combination, within a given territory, of a social unit and a cultural plurality by way of exchanges and communications among actors who use different categories of expression, analysis and interpretation. A multiculturalist project should not promote a society that is split up into closed groups; on the contrary, it should set forth policies based on communication and cooperation processes among the cultural communities. To understand this concept, we will present the ontological basis of this phenomenonin the search for a communicational solution, with our startpoint being a phenomenological description of the way in which multiculturalism manifests to us in life; to later deepen into the meaning of the phenomenon,and finally offer a pluralist solution to the problems and challenges cultural differences bring about.

  11. Hypnosis phenomenology and the neurobiology of consciousness.

    Science.gov (United States)

    Rainville, Pierre; Price, Donald D

    2003-04-01

    Recent developments in the philosophical and neurobiological studies of consciousness provide promising frameworks to investigate the neurobiology of hypnosis. A model of consciousness phenomenology is described to demonstrate that the experiential dimensions characterizing hypnosis (relaxation and mental ease, absorption, orientation and monitoring, and self-agency) reflect basic phenomenal properties of consciousness. Changes in relaxation-mental ease and absorption, produced by standard hypnotic procedures, are further associated with changes in brain activity within structures critically involved in the basic representation of the body-self and the regulation of states of consciousness. The combination of experiential and modern brain imaging methods offers a unique perspective on hypnotic phenomena and provides new observations consistent with the proposition that hypnosis is an altered state of consciousness.

  12. Warped Phenomenology of Higher-Derivative Gravity

    Energy Technology Data Exchange (ETDEWEB)

    Rizzo, T.

    2004-12-06

    We examine the phenomenological implications at colliders for the existence of higher-derivative gravity terms as extensions to the Randall-Sundrum model. Such terms are expected to arise on rather general grounds, e.g., from string theory. In 5-d, if we demand that the theory be unitary and ghost free, these new contributions to the bulk action are uniquely of the Gauss-Bonnet form. We demonstrate that the usual expectations for the production cross section and detailed properties of graviton Kaluza-Klein resonances and TeV-scale black holes can be substantially altered by existence of these additional contributions. It is shown that measurements at future colliders will be highly sensitive to the presence of such terms.

    Peckham, D. W.; Uman, M. A.; Wilcox, C. E., Jr.

    1984-01-01

    A commercial lightning-locating system (LLS) was employed in the study of lightning phenomenology in the Tampa Bay area of Florida. The LLS output included the time, location, number of strokes per flash, and initial peak magnetic field value of first strokes for lightning ground flashes lowering negative charge. Attention is given to the design and the operation of the LLS, and the experimental results. Measured properties of each of 111 storms are given in a number of tables. It was observed that the apparent motion associated with the lightning activity in storm systems was not due to the motion of the individual single-peak and multiple-peak storms but rather to the successive growth of new storms near previously active storms.

  14. Extended inertial range phenomenology of magnetohydrodynamic turbulence

    Science.gov (United States)

    Matthaeus, William H.; Zhou, YE

    1989-01-01

    A phenomenological treatment of the inertial range of isotropic statistically steady magnetohydrodynamic turbulence is presented, extending the theory of Kraichnan (1965). The role of Alfven wave propagation is treated on equal footing with nonlinear convection, leading to a simple generalization of the relations between the times characteristic of wave propagation, convection, energy transfer, and decay of triple correlations. The theory leads to a closed-form steady inertial range spectral law that reduces to the Kraichnan and Kolmogorov laws in appropriate limits. The Kraichnan constant is found to be related in a simple way to the Kolmogorov constant; for typical values of the latter constant, the former has values in the range 1.22-1.87. Estimates of the time scale associated with spectral transfer of energy also emerge from the new approach, generalizing previously presented 'golden rules' for relating the spectral transfer time scale to the Alfven and eddy-turnover time scales.

    Directory of Open Access Journals (Sweden)

    Gregory Cameron

    2011-12-01

    Full Text Available “Politics and the Internet” is a critique of the political potential of the internet from the perspective of Husserl’s discussion of intersubjectivity and objectivity in Cartesian Meditations and Origins of Geometry. Unlike other critiques of the internet from a phenomenological perspective, this paper does not consider the limitations of internet communication from the perspective of the body. Here, rather, the prime concern is with the constitution of objectivity and the ways in which the internet limits this constitution. The paper builds towards a consideration of the essential role of objectivity as a condition of possibility for politics and community. Implicit in the argument is a defence of print and broadcast media.

    The classical Hamiltonian of the interacting boson model is defined and expressed in terms of the conventional quadrupole variables. This is used in the analyses of the dynamics in the various limits of the model. The purpose is to determine the range and the features of the collective phenomena which the interacting boson model is capable of describing. In the commonly used version of the interacting boson model with one type of the s and d bosons and quartic interactions, this capability has certain limitations and the model should be used with care. A more sophisticated version of the interacting boson model with neutron and proton bosons is not discussed.

  17. The auditory hallucination: a phenomenological survey.

    Science.gov (United States)

    Nayani, T H; David, A S

    1996-01-01

    A comprehensive semi-structured questionnaire was administered to 100 psychotic patients who had experienced auditory hallucinations. The aim was to extend the phenomenology of the hallucination into areas of both form and content and also to guide future theoretical development. All subjects heard 'voices' talking to or about them. The location of the voice, its characteristics and the nature of address were described. Precipitants and alleviating factors plus the effect of the hallucinations on the sufferer were identified. Other hallucinatory experiences, thought insertion and insight were examined for their inter-relationships. A pattern emerged of increasing complexity of the auditory-verbal hallucination over time by a process of accretion, with the addition of more voices and extended dialogues, and more intimacy between subject and voice. Such evolution seemed to relate to the lessening of distress and improved coping. These findings should inform both neurological and cognitive accounts of the pathogenesis of auditory hallucinations in psychotic disorders.

    Singsuriya, Pagorn

    2015-12-01

    Paul Ricoeur's hermeneutic phenomenology has proved to be very helpful in guiding nursing researchers' qualitative analysis of interview transcripts. Modifying Ricoeur's philosophy, a number of nursing researchers have developed their own interpretive methods and shared them, along with their experience, with research community. Major contributors who published papers directly presenting their modifications of Ricoeur's theory include Rene Geanellos (2000), Lena Wiklund, Lisbet Lindholm and Unni Å. Lindström (2002), Anders Lindseth and Astrid Norberg (2004) and Pia Sander Dreyer and Birthe D Pedersen (2009). The aim of this article was to delineate differences among these methods. Descriptive presentation of each method side by side makes clear the differences among them. In addition, Ricoeur's hermeneutic theory is portrayed and compared with the modifications. It is believed that differences that are found can stimulate further thoughts on how to apply Ricoeur's theory in qualitative research in nursing.

    2010-01-01

    give a brief overview of the phenomenology related to the measurements of the last unknown lepton mixing angle !13, CP violation (CPV) in neutrino os- cillations, and the neutrino mass hierarchy (MH). Sensitivities of upcoming reactor and accelerator experiments to !13 are discussed, showing that within a few years values of sin2 2!13 ! 10−2 will be probed, while CPV andMH mea- surements will be very difÞcult with that generation of experiments. I make some selected remarks on CPV andMH determinations with a subsequent gen- eration of experiment consisting of a high precision/high luminosity oscillation facility. In particular, I emphasize the possibility to explore synergies of such an advanced accelerator facility with a huge multi-purpose detector.

Finally, we introduce the concept of thermalscapes, giving attention to the relatively neglected role of temperatures in tourism experiences.......This paper suggests that phenomenological studies of tourism mobilities can be informed by non-representational approaches. We extend recent developments in sensory tourism research and non-representational works to argue that methods upon which tourism researchers have long relied require ‘pushing......’ or merging in previously underutilised ways that support these emerging areas of study. As a result, this paper embraces embodied methodologies. It integrates audio-visual impressionistic tales and netnographic snippets to shape its multisensory exploration of an under-researched European tourism and train...

  1. Chief Nursing Officer Sustainment: A Phenomenological Inquiry.

    2015-11-01

    The study explored factors leading to chief nursing officer (CNO) sustainment in the professional practice of nurse executive leadership. CNOs are expected to lead adaptations in care delivery in this current era of healthcare reform, requiring a multitude of new leadership skills. Exploration is needed to understand barriers to longevity, which prevent consistency of leadership and execution of vision. Twenty CNOs were interviewed to determine the lived experience related to the phenomena of role sustainment. An interpretative phenomenological analysis approach was used. Six themes emerged describing sustainment. These are as follows: loving the profession, having a broader impact, reflecting on one's own work, learning to manage conflict, maintaining work/life balance, and working with supportive leaders. The desire and passion for nurse executive leadership must be enhanced through education and competencies that emerged in this study and include strategic processing, mindful reflection, and resiliency training.

  2. Toward a phenomenology of inner speaking.

    Inner speaking is a common and widely discussed phenomenon of inner experience. Based on our studies of inner experience using Descriptive Experience Sampling (a qualitative method designed to produce high fidelity descriptions of randomly selected pristine inner experience), we advance an initial phenomenology of inner speaking. Inner speaking does occur in many, though certainly not all, moments of pristine inner experience. Most commonly it is experienced by the person as speaking in his or her own naturally inflected voice but with no sound being produced. In addition to prototypical instances of inner speaking, there are wide-ranging variations that fit the broad category of inner speaking and large individual differences in the frequency with which individuals experience inner speaking. Our observations are discrepant from what many have said about inner speaking, which we attribute to the characteristics of the methods different researchers have used to examine inner speaking.

  3. Effective Lagrangians and Light Gravitino Phenomenology

    Luty, M A; Luty, Markus A.; Ponton, Eduardo

    1998-01-01

    We construct the low-energy effective lagrangian for supersymmetry breaking models with a light gravitino. Our effective lagrangian is written in terms of the spin-1/2 Goldstino (the longitudinal component of the gravitino) transforming under a non-linear realization of supersymmetry. The Goldstino is derivatively coupled. We use this lagrangian to place bounds on the supersymmetry breaking scale \\sqrt{F} from Goldstino phenomenology. The most stringent bounds come from the coupling of a single photon to Goldstino pairs. For gauge-mediated models, this coupling arises at one loop in the effective lagrangian, and supernova cooling allows \\sqrt{F} > 610 GeV or \\sqrt{F} 140 GeV for tan\\beta = 2.

    We show that an invariant an universal length scale can be consistently introduced in a generally covariant theory through the gravitational sector using the Palatini approach. The resulting theory is able to capture different aspects of quantum gravity phenomenology in a single framework. In particular, it is found that in this theory field excitations propagating with different energy-densities perceive different background metrics, which is a fundamental characteristic of the DSR and Rainbow Gravity approaches. We illustrate these properties with a particular gravitational model and explicitly show how the soccer ball problem is avoided in this framework. The isotropic and anisotropic cosmologies of this model also avoid the big bang singularity by means of a big bounce.

  5. Differentiating between descriptive and interpretive phenomenological research approaches.

    To provide insight into how descriptive and interpretive phenomenological research approaches can guide nurse researchers during the generation and application of knowledge. Phenomenology is a discipline that investigates people's experiences to reveal what lies 'hidden' in them. It has become a major philosophy and research method in the humanities, human sciences and arts. Phenomenology has transitioned from descriptive phenomenology, which emphasises the 'pure' description of people's experiences, to the 'interpretation' of such experiences, as in hermeneutic phenomenology. However, nurse researchers are still challenged by the epistemological and methodological tenets of these two methods. The data came from relevant online databases and research books. A review of selected peer-reviewed research and discussion papers published between January 1990 and December 2013 was conducted using CINAHL, Science Direct, PubMed and Google Scholar databases. In addition, selected textbooks that addressed phenomenology as a philosophy and as a research methodology were used. Evidence from the literature indicates that most studies following the 'descriptive approach' to research are used to illuminate poorly understood aspects of experiences. In contrast, the 'interpretive/hermeneutic approach' is used to examine contextual features of an experience in relation to other influences such as culture, gender, employment or wellbeing of people or groups experiencing the phenomenon. This allows investigators to arrive at a deeper understanding of the experience, so that caregivers can derive requisite knowledge needed to address such clients' needs. Novice nurse researchers should endeavour to understand phenomenology both as a philosophy and research method. This is vitally important because in-depth understanding of phenomenology ensures that the most appropriate method is chosen to implement a study and to generate knowledge for nursing practice. This paper adds to the current

    Full Text Available Mika Elo is a postdoctoral researcher and lecturer in visual culture at Aalto University School of Arts, Design and Architecture (Aalto-ARTS, Helsinki. His research interests include theory of photographic media, philosophical media theory, and artistic research. He is participating in discussions in these areas in the capacity of curator, visual artist and researcher. He has published articles in Finnish, German, and English among others on Benjamin, Nancy, artistic research and photography theory. His doctoral thesis Valokuvan medium [The Medium of Photography] was published in Finnish in 2005 (Tutkijaliitto, Helsinki. In 2009–2011 he worked in the Figures of Touch research project (figuresoftouch.com, and since 2011 he is the director of Media Aesthetics research group at Aalto-ARTS, Department of Media.Author Biography The article reflects on digitality and interface design in terms of the multiple senses of touch. Touching is presented as a “pathic” sense of being exposed, which implies that touching exceeds the tactile and even the phenomenal world. A particular focus is set on Aristotle's and Husserl's ways of thematizing the sense of touch. In this way, two extremes of the phenomenological thinking of touching are articulated: touching as an indistinct and heterogeneous constituent of sensitivity and touching as the guarantor of immediacy of the sense experience. Referring to Derrida's critical notes concerning haptocentrism, the article attempts to problematize the hand and the finger as phenomenological figures of touch and as holds of haptic realism. The article concludes that insofar as digital interface design aims at haptic realism it conceives of the sense of touch in terms of narcissistic feedback and thus tends to conceal the pathic moment of touching.

  7. Resurrecting no-scale supergravity phenomenology

    In the context of phenomenological models in which the soft supersymmetry-breaking parameters of the MSSM become universal at some unification scale, M{sub in}, above the GUT scale, M{sub GUT}, it is possible that all the scalar mass parameters m{sub 0}, the trilinear couplings A{sub 0} and the bilinear Higgs coupling B{sub 0} vanish simultaneously, as in no-scale supergravity. Using these no-scale inputs in a renormalisation-group analysis of the minimal supersymmetric SU(5) GUT model, we pay careful attention to the matching of parameters at the GUT scale. We delineate the region of M{sub in}, m{sub 1/2} and tan {beta} where the resurrection of no-scale supergravity is possible, taking due account of the relevant phenomenological constraints such as electroweak symmetry breaking, m{sub h},b {yields}s {gamma}, the neutralino cold dark matter density {omega}{sub {chi}} h {sup 2} and g{sub {mu}} -2. No-scale supergravity survives in an L-shaped strip of parameter space, with one side having m{sub 1/2}>or similar 200 GeV, the second (orthogonal) side having M{sub in}>or similar 5 x 10 {sup 16} GeV. Depending on the relative signs and magnitudes of the GUT superpotential couplings, these may be connected to form a triangle whose third side is a hypotenuse at larger M{sub in}, m{sub 1/2} and tan {beta}, whose presence and location depend on the GUT superpotential parameters. We compare the prospects for detecting sparticles at the LHC in no-scale supergravity with those in the CMSSM and the NUHM. (orig.)

  8. The phenomenology of the intersubjective impairment.

    Hipolito, Ines

    2016-08-01

    Several studies suggest that the disorders of the self include a disturbance of the most elementary component of self - the minimal self. Characterizing these disorders and understanding the mechanisms involved remain a challenge to medical epistemology and health care professionals. In the present work, I bring together concepts of different fields, such as neuroscience, epistemology and phenomenology. The main goal is to show that the second-person perspective can be used to point out particular features of social cognition and its related psychopathology. Taking the hypothesis that the second-person perspective is the congruence point between an objective process and the subjective experience, I will attempt to explain schizophrenia as a self-related deficit, first in the light of the first-person and the third-person perspective and afterward, in the light of the poorly less understood second-person perspective. On the one hand, the first-person experience is correlated both with space and time. In fact, psychiatric patients report subjective experiences that can be understood within research on the bodily self, such as (1) spatially incongruent proprioception and (2) impaired sense of time as the basic mechanism that allows conscious experience. On the other hand, the second-person approach has already begun to prove productive within social cognition research, pointing out the importance of experiencing and interacting with others as our primarily way well-being. I will phenomenological analyse subjective and intersubjective experience in the disorders of the self and derive practical consequences to evidence-based medicine.

  10. Disentangling attention from action in the emotional spatial cueing task.

    Mulckhuyse, Manon; Crombez, Geert

    2014-01-01

    In the emotional spatial cueing task, a peripheral cue--either emotional or non-emotional--is presented before target onset. A stronger cue validity effect with an emotional relative to a non-emotional cue (i.e., more efficient responding to validly cued targets relative to invalidly cued targets) is taken as an indication of emotional modulation of attentional processes. However, results from previous emotional spatial cueing studies are not consistent. Some studies find an effect at the validly cued location (shorter reaction times compared to a non-emotional cue), whereas other studies find an effect at the invalidly cued location (longer reaction times compared to a non-emotional cue). In the current paper, we explore which parameters affect emotional modulation of the cue validity effect in the spatial cueing task. Results from five experiments in healthy volunteers led to the conclusion that a threatening spatial cue did not affect attention processes but rather indicate that motor processes are affected. A possible mechanism might be that a strong aversive cue stimulus decreases reaction times by means of stronger action preparation. Consequently, in case of a spatially congruent response with the peripheral cue, a stronger cue validity effect could be obtained due to stronger response priming. The implications for future research are discussed.

  11. Neural mechanisms of cue-approach training.

    2017-05-01

    Biasing choices may prove a useful way to implement behavior change. Previous work has shown that a simple training task (the cue-approach task), which does not rely on external reinforcement, can robustly influence choice behavior by biasing choice toward items that were targeted during training. In the current study, we replicate previous behavioral findings and explore the neural mechanisms underlying the shift in preferences following cue-approach training. Given recent successes in the development and application of machine learning techniques to task-based fMRI data, which have advanced understanding of the neural substrates of cognition, we sought to leverage the power of these techniques to better understand neural changes during cue-approach training that subsequently led to a shift in choice behavior. Contrary to our expectations, we found that machine learning techniques applied to fMRI data during non-reinforced training were unsuccessful in elucidating the neural mechanism underlying the behavioral effect. However, univariate analyses during training revealed that the relationship between BOLD and choices for Go items increases as training progresses compared to choices of NoGo items primarily in lateral prefrontal cortical areas. This new imaging finding suggests that preferences are shifted via differential engagement of task control networks that interact with value networks during cue-approach training.

  14. Development of cue integration in human navigation.

    Science.gov (United States)

    Nardini, Marko; Jones, Peter; Bedford, Rachael; Braddick, Oliver

    2008-05-06

    Mammalian navigation depends both on visual landmarks and on self-generated (e.g., vestibular and proprioceptive) cues that signal the organism's own movement [1-5]. When these conflict, landmarks can either reset estimates of self-motion or be integrated with them [6-9]. We asked how humans combine these information sources and whether children, who use both from a young age [10-12], combine them as adults do. Participants attempted to return an object to its original place in an arena when given either visual landmarks only, nonvisual self-motion information only, or both. Adults, but not 4- to 5-year-olds or 7- to 8-year-olds, reduced their response variance when both information sources were available. In an additional "conflict" condition that measured relative reliance on landmarks and self-motion, we predicted behavior under two models: integration (weighted averaging) of the cues and alternation between them. Adults' behavior was predicted by integration, in which the cues were weighted nearly optimally to reduce variance, whereas children's behavior was predicted by alternation. These results suggest that development of individual spatial-representational systems precedes development of the capacity to combine these within a common reference frame. Humans can integrate spatial cues nearly optimally to navigate, but this ability depends on an extended developmental process.

  15. Cue-specific reactivity in experienced gamblers.

    Wulfert, Edelgard; Maxson, Julie; Jardin, Bianca

    2009-12-01

    To examine whether gambling cue reactivity is cue-specific, 47 scratch-off lottery players and 47 horse race gamblers were presented with video clips of their preferred and nonpreferred modes of gambling, and two control stimuli including an exciting car race and a mental stressor task while heart rates, excitement, and urge to gamble were being measured. Heart rates for both groups of gamblers were highest to the mental stressor and did not differ in response to the other three cues. Excitement for both groups was highest in response to the action cues (horse race and car chase). Urge to gamble was significantly higher for each group to their preferred mode of gambling. A post hoc exploratory analysis comparing social gamblers (n = 54) and probable pathological gamblers (n = 40) revealed a similar pattern of responses. However, pathological gamblers reported overall significantly higher urges to gamble than social gamblers. As urges have been shown to play a pivotal role in addictive behaviors and relapse, the current findings may have implications for the development of gambling problems and relapse after successful treatment.

  18. The (unclear effects of invalid retro-cues.

    2016-03-01

    Full Text Available Studies with the retro-cue paradigm have shown that validly cueing objects in visual working memory long after encoding can still benefit performance on subsequent change detection tasks. With regard to the effects of invalid cues, the literature is less clear. Some studies reported costs, others did not. We here revisit two recent studies that made interesting suggestions concerning invalid retro-cues: One study suggested that costs only occur for larger set sizes, and another study suggested that inclusion of invalid retro-cues diminishes the retro-cue benefit. New data from one experiment and a reanalysis of published data are provided to address these conclusions. The new data clearly show costs (and benefits that were independent of set size, and the reanalysis suggests no influence of the inclusion of invalid retro-cues on the retro-cue benefit. Thus, previous interpretations may be taken with some caution at present.

  19. Cue-induced craving in patients with cocaine use disorder predicts cognitive control deficits toward cocaine cues.

    2015-08-01

    Cue-induced craving is a clinically important aspect of cocaine addiction influencing ongoing use and sobriety. However, little is known about the relationship between cue-induced craving and cognitive control toward cocaine cues. While studies suggest that cocaine users have an attentional bias toward cocaine cues, the present study extends this research by testing if cocaine use disorder patients (CDPs) can control their eye movements toward cocaine cues and whether their response varied by cue-induced craving intensity. Thirty CDPs underwent a cue exposure procedure to dichotomize them into high and low craving groups followed by a modified antisaccade task in which subjects were asked to control their eye movements toward either a cocaine or neutral drug cue by looking away from the suddenly presented cue. The relationship between breakdowns in cognitive control (as measured by eye errors) and cue-induced craving (changes in self-reported craving following cocaine cue exposure) was investigated. CDPs overall made significantly more errors toward cocaine cues compared to neutral cues, with higher cravers making significantly more errors than lower cravers even though they did not differ significantly in addiction severity, impulsivity, anxiety, or depression levels. Cue-induced craving was the only specific and significant predictor of subsequent errors toward cocaine cues. Cue-induced craving directly and specifically relates to breakdowns of cognitive control toward cocaine cues in CDPs, with higher cravers being more susceptible. Hence, it may be useful identifying high cravers and target treatment toward curbing craving to decrease the likelihood of a subsequent breakdown in control. Copyright © 2015 Elsevier Ltd.

  20. On the phenomenology of empathy in nursing: empathy or sympathy?

    Science.gov (United States)

    Yegdich, T

    1999-07-01

    In her recent phenomenological study Baillie attempted to describe the essential structure of empathy in surgical nursing. The study is important in that it utilizes a qualitative research method to investigate the phenomena of empathy, in contrast to previous quantitative studies. Although the phenomenological approach is clearly identified and ascribed to Husserl as the founder of the phenomenological movement, as well as utilizing the peculiarly Husserlian notion of bracketing, or epoché, in an attempt to describe the essence (another Husserlian objective) of the phenomenon under investigation (empathy), the research method does not reflect Husserl's philosophy. The results reflect nurses' subjective views on empathy, an exercise consistent with the nurse-phenomenologists quoted, who without exception, all believe Husserlian phenomenology concerns itself with subjective experience. However, in seeking the essence of phenomena unclouded by subjective opinion, Husserl stands in contrast to nursing interpretations of phenomenology's famous catch phrase, 'back to the things themselves' (zu den Sachen selbst). Nurse-phenomenologists have misunderstood the intention of Husserlian phenomenology, and despite their opposition to traditional scientific methods, are still mired in the Kantian notion of science as a reality independent of mind. A theme consistent with the 'things-in-themselves', not the things themselves. As such, nursing's use of the phenomenological method is questionable, and therefore the research findings on the phenomenon of empathy need to be reformulated. Interestingly, the phenomenon of empathy challenges us to question such underlying assumptions on how we view the world.

    Full Text Available The aim of present study is to understand the reasons of pre-service teachers for academic cheating. The study used phenomenological design and descriptive phenomenological approach was adapted. The participants were selected by using homogenous sampling strategy and data were collected through in depth interviews from six volunteer pre-service teachers which are a woman and five men. In analysis of the research data, thematic analysis approach was utilized. As a result of the analysis, two themes were constructed to explain the reasons for cheating that are personal factors and environmental factors. The personal factors are comprised of personal characteristics, academic gains and insufficient self-perception. The environmental factors affecting cheating behaviors are instructor’s attitudes and behaviors, exam-based evaluation system, the role of courses, peer effect, institutional features and family expectations.Keywords: Cheating, preservice teachers, qualitative research, phenomenology ÖzBu araştırmanın amacı öğretmen adaylarının kopya çekme davranışlarının nedenlerini incelemektir.

    Miles, Maureen; Francis, Karen; Chapman, Ysanne; Taylor, Beverley

    2013-08-01

    Hermeneutic phenomenology has been used widely by researchers to understand lived experiences. This methodology asserts that individual people are as unique as their life stories. The practice of midwifery is underpinned by a philosophy that values women and the uniqueness of their child-bearing journey. The tenets of hermeneutics phenomenology align with those of contemporary midwifery practice, making it a useful research methodology for providing insights into issues relevant to the profession. The purpose of this paper is to unravel some foundational concepts of hermeneutic phenomenology and recommend it as a methodology of choice for midwives to apply to their application to midwifery-in-action.

Influenced most particularly by the phenomenological movement, our collaborative dialogue over more than four decades has led us to a shared commitment to reflection upon the philosophical underpinnings and constitutive contexts of origin of all our theoretical ideas. The growth of our thinking follows an endlessly recurring phenomenological circle joining theoretical perspectives with the inquirers from whose emotional worlds they arise.

    For a population with any given number of types, we construct a new multivariate Moran process with frequency-dependent selection and establish, analytically, a correspondence to equilibrium Lotka-Volterra phenomenology. This correspondence, on the one hand, allows us to infer the phenomenology of our Moran process based on much simpler Lokta-Volterra phenomenology and, on the other, allows us to study Lotka-Volterra dynamics within the finite populations of a Moran process. Applications to community ecology, population genetics, and evolutionary game theory are discussed.

    We present a new environment for computations in particle physics phenomenology employing recent developments in cloud computing. On this environment users can create and manage ''virtual'' machines on which the phenomenology codes/tools can be deployed easily in an automated way. We analyze the performance of this environment based on ''virtual'' machines versus the utilization of physical hardware.

  13. The phenomenology of maverick dark matter

    Science.gov (United States)

    Krusberg, Zosia Anna Celina

    Astrophysical observations from galactic to cosmological scales point to a substantial non-baryonic component to the universe's total matter density. Although very little is presently known about the physical properties of dark matter, its existence offers some of the most compelling evidence for physics beyond the standard model (BSM). In the weakly interacting massive particle (WIMP) scenario, the dark matter consists of particles that possess weak-scale interactions with the particles of the standard model, offering a compelling theoretical framework that allows us to understand the relic abundance of dark matter as a natural consequence of the thermal history of the early universe. From the perspective of particle physics phenomenology, the WIMP scenario is appealing for two additional reasons. First, many theories of BSM physics contain attractive WIMP candidates. Second, the weak-scale interactions between WIMPs and standard model particles imply the possibility of detecting scatterings between relic WIMPs and detector nuclei in direct detection experiments, products of WIMP annihilations at locations throughout the galaxy in indirect detection programs, and WIMP production signals at high-energy particle colliders. In this work, we use an effective field theory approach to study model-independent dark matter phenomenology in direct detection and collider experiments. The maverick dark matter scenario is defined by an effective field theory in which the WIMP is the only new particle within the energy range accessible to the Large Hadron Collider (LHC). Although certain assumptions are necessary to keep the problem tractable, we describe our WIMP candidate generically by specifying only its spin and dominant interaction form with standard model particles. Constraints are placed on the masses and coupling constants of the maverick WIMPs using the Wilkinson Microwave Anisotropy Probe (WMAP) relic density measurement and direct detection exclusion data from both

  14. The Phenomenology of Flipped SU(5)

    Abel, S. A.

    1990-01-01

    Available from UMI in association with The British Library. In this thesis, I examine the phenomenology of the supersymmetric flipped SU(5) model. Such a model has been derived as a low energy approximation to heterotic string theory, probably with a 'no-scale' supersymmetry breaking mechanism. It is found that a large region of the flipped SU(5) parameter space predicts a satisfactory breaking down to the standard model on renormalization down to low energies. In particular it contains a number of phenomenological advantages over other GUT schemes, such as a natural Higg's doublet-triplet mass splitting, and a neutrino see-saw mechanism. Analysis of the neutrino sector shows that this model may allow rapid decays of the heavy neutrinos into lighter electron-neutrinos. This is due to new flavour changing couplings in the superpotential, which are included in the neutrino mass matrix. Such fast decays may be able to evade certain cosmological bounds, based on the standard inflationary scenarios and the observation of the 3K background radiation. Thus it is possible that neutrinos could form a substantial proportion of the dark matter in the Universe. Rare processes may be significantly enhanced in the flipped SU(5) scenario, due to new couplings whose off diagonal Kobayashi-Maskawa matrix elements need not be small. In particular, the gaugino-fermion-sfermion coupling may give important new flavour changing diagrams, since, after supersymmetry is broken, the fermions and sfermions are no longer simultaneously diagonalizable. This leads to the possibility of decays such as Z to bs and muto egamma being detected in the near future. In addition to this there are significant new contributions to the electric dipole moment of the neutron which may be as high as the present day limit of | d_ n| < 10^{-25}ecm. Support for this model may come from neutralino contributions to the number of 'neutrino species' measured in Z decays. Finally, the anomalous magnetic moment of the

    In the current study, we aimed to extend smoking cue-reactivity research by evaluating delay discounting as an outcome of cigarette cue exposure. We also separated introspection in response to cues (e.g., self-reporting craving and affect) from cue exposure alone, to determine if introspection changes behavioral responses to cigarette cues. Finally, we included measures of quit motivation and resistance to smoking to assess motivational influences on cue exposure. Smokers were invited to participate in an online cue-reactivity study. Participants were randomly assigned to view smoking images or neutral images, and were randomized to respond to cues with either craving and affect questions (e.g., introspection) or filler questions. Following cue exposure, participants completed a delay discounting task and then reported state affect, craving, and resistance to smoking, as well as an assessment of quit motivation. We found that after controlling for trait impulsivity, participants who introspected on craving and affect showed higher delay discounting, irrespective of cue type, but we found no effect of response condition on subsequent craving (e.g., craving reactivity). We also found that motivation to quit interacted with experimental conditions to predict state craving and state resistance to smoking. Although asking about craving during cue exposure did not increase later craving, it resulted in greater delaying of discounted rewards. Overall, our findings suggest the need to further assess the implications of introspection and motivation on behavioral outcomes of cue exposure.

    The dynamics of photoevaporated molecular clouds is determined by the ablative pressure acting on the ionization front. An important step in the understanding of the ensuing motion is to develop the linear stability theory for the initially flat front. Despite the simplifications introduced by the linearization, the problem remains quite complex and still draws a lot of attention. The complexity is related to the large number of effects that have to be included in the analysis: acceleration of the front, possible temporal variation of the intensity of the ionizing radiation, the tilt of the radiation flux with respect to the normal to the surface, and partial absorption of the incident radiation in the ablated material. In this paper, we describe a model where all these effects can be taken into account simultaneously, and a relatively simple and universal dispersion relation can be obtained. The proposed phenomenological model may prove to be a helpful tool in assessing the feasibility of the laboratory experiments directed towards scaled modeling of astrophysical phenomena.

  17. Dante's inferno: phenomenology of a strange passion.

    Science.gov (United States)

    De Monticelli, R

    2000-01-01

    Dante's Inferno presents us with a spiritual adventure where the experience of wrath plays a crucial role. The infernal pilgrim's 'passage through wrath' is their only access to the lower part of Hell. Wrath - and the place where it is punished as a vice - occupy a very central position in the moral topography of Dante's Inferno: the Stygian Marsh, which defends the heart of Hell, its stronghold, and makes it inaccessible. Wrathfulness is situated at the borderline between 'carnal' and 'spiritual' sins, higher and lower Hell, weakness and wickedness of the will. What is the meaning of this situation? How is the sin of wrathfulness related to wrath as an expression of just indignation? How can the same passion have an angelical and an infernal face? What is anger's relation to reason? Does the trial gone through by the two pilgrims teach us something on the nature of this passion? Here are some questions which this paper tries to answer, thereby outlining a phenomenological theory of those passions which might be called 'dynamic'. Copyright 2000 S. Karger AG, Basel

    2017-01-01

    Background: Projectile breakup can make a large contribution to reactions induced by projectiles with mass numbers 2, 3, and 4, yet there is no global model for it and no clear agreement on the details of the reaction mechanism. Purpose: This project aims to develop a phenomenological model for light-projectile breakup that can guide the development of detailed theories and provide a useful tool for applied calculations. Method: An extensive database of double-differential cross sections for the breakup of deuterons, 3He ions, and α particles was assembled from the literature and analyzed in a consistent way. Results: Global systematics for the centroid energies, peak widths, and angular distributions of the breakup peaks have been extracted from the data. The dominant mechanism appears to be absorptive breakup, where the unobserved projectile fragment fuses with the target nucleus during the initial interaction. The global target-mass-number and incident-energy dependencies of the absorptive breakup cross section have also been determined, along with channel-specific normalization constants. Conclusions: Results from the model generally agree with the original data after subtraction of a reasonable underlying continuum. Absorptive breakup can account for as much as 50%-60% of the total reaction cross section.

  19. Phenomenology of Compositeness at the LHC

    CERN Document Server

    Salvioni, Ennio; Zwirner, Fabio

    The hierarchy problem of the weak scale calls for extensions of the Standard Model at the TeV, and thus within the reach of the CERN Large Hadron Collider (LHC). One of the best motivated proposals builds on the idea that the Higgs could be a composite pseudo-Nambu-Goldstone boson. In this thesis we discuss several topics in the phenomenology of composite Higgs models, concentrating mainly on LHC physics. In Chapter 1 we introduce the hierarchy problem and the essential features of viable theories of compositeness at the TeV scale. Chapter 2 is dedicated to a review of concrete constructions realizing the composite Higgs idea, focusing mostly on models with partial compositeness. In Chapter 3 we present the effective Lagrangians suited for describing the Higgs boson and the constraints placed by electroweak precision tests on their parameters. Motivated by hints in the experimental results, we also reconsider the possibility of custodial breaking in the couplings of the Higgs to the W and Z. Chapter 4 is devo...

    2016-01-01

    We present some of the topics covered in two lectures under the same title that was given at the "Summer School on High Energy Physics at the LHC: New trends in HEP" in Natal, Brazil. In this contribution we give a brief review on the application of perturbative QCD to the hard diffractive processes. Such reactions involving a hard scale can be understood in terms of quarks and gluons degrees of freedom and have become an useful tool for investigating the low-$x$ structure of the proton and the behavior of QCD in the high-density regime. We start using the information from the $ep$ collisions at HERA concerned to the inclusive diffraction to introduce the concept of diffractive parton distributions. Their interpretation in the resolved pomeron model is addressed and we discuss the limits of diffractive hard-scattering factorization for hadron-hadron collisions. Some examples of phenomenology for the diffractive production of $W/Z$, heavy $Q\\bar{Q}$ and quarkonium in hadron-hadron reactions are presented. We a...

  1. New Results in Light-Front Phenomenology

    2004-01-01

    The light-front quantization of gauge theories such as QCD in light-cone gauge provides a frame-independent wavefunction representation of relativistic bound states, simple forms for current matrix elements, explicit unitarity, and a trivial vacuum. The freedom to choose the light-like quantization four-vector provides an explicitly covariant formulation of light-front quantization and can be used to determine the analytic structure of light-front wave functions and to define a kinematical definition of angular momentum. The AdS/CFT correspondence of large $N_C$ supergravity theory in higher-dimensional anti-de Sitter space with supersymmetric QCD in 4-dimensional space-time has interesting implications for hadron phenomenology in the conformal limit, including an all-orders demonstration of counting rules for exclusive processes. String/gauge duality also predicts the QCD power-law behavior of light-front Fock-state hadronic wavefunctions with arbitrary orbital angular momentum at high momentum transfer. The...

  2. Phenomenology in minimal theory of massive gravity

    De Felice, Antonio

    2015-01-01

    We investigate the minimal theory of massive gravity (MTMG) recently introduced. After reviewing the original construction based on its Hamiltonian in the vielbein formalism, we reformulate it in terms of its Lagrangian in both the vielbein and the metric formalisms. It then becomes obvious that, unlike previous attempts in the literature, not only the potential but also the kinetic structure of the action is modified from the de Rham-Gabadadze-Tolley (dRGT) massive gravity theory. We confirm that the number of physical degrees of freedom in MTMG is two at fully nonlinear level. This proves the absence of various possible pathologies such as superluminality, acausality and strong coupling. Afterwards, we discuss the phenomenology of MTMG in the presence of a dust fluid. We find that on a flat homogeneous and isotropic background we have two branches. One of them (self-accelerating branch) naturally leads to acceleration without the genuine cosmological constant or dark energy. For this branch both the scalar ...

  3. Conciliating neuroscience and phenomenology via category theory.

    Ehresmann, Andrée C; Gomez-Ramirez, Jaime

    2015-12-01

    The paper discusses how neural and mental processes correlate for developing cognitive abilities like memory or spatial representation and allowing the emergence of higher cognitive processes up to embodied cognition, consciousness and creativity. It is done via the presentation of MENS (for Memory Evolutive Neural System), a mathematical methodology, based on category theory, which encompasses the neural and mental systems and analyzes their dynamics in the process of 'becoming'. Using the categorical notion of a colimit, it describes the generation of mental objects through the iterative binding of distributed synchronous assemblies of neurons, and presents a new rationale of spatial representation in the hippocampus (Gómez-Ramirez and Sanz, 2011). An important result is that the degeneracy of the neural code (Edelman, 1989) is the property allowing for the formation of mental objects and cognitive processes of increasing complexity order, with multiple neuronal realizabilities; it is essential "to explain certain empirical phenomena like productivity and systematicity of thought and thinking (Aydede 2010)". Rather than restricting the discourse to linguistics or philosophy of mind, the formal methods used in MENS lead to precise notions of Compositionality, Productivity and Systematicity, which overcome the dichotomic debate of classicism vs. connectionism and their multiple facets. It also allows developing the naturalized phenomenology approach asked for by Varela (1996) which "seeks articulations by mutual constraints between phenomena present in experience and the correlative field of phenomena established by the cognitive sciences", while avoiding their pitfalls.

    This project tackles the problem of conversion of validated a priori physics-based modeling capabilities, specifically those relevant to the analysis and interpretation of planetary atmosphere observations, to application-oriented software for use in science and science-support activities. The software package under development, named the Photochemical Phenomenology Modeling Tool (PPMT), has particular focus on the atmospheric remote sensing data to be acquired by the CIRS instrument during the CASSINI Jupiter flyby and orbital tour of the Saturnian system. Overall, the project has followed the development outline given in the original proposal, and the Year 1 design and architecture goals have been met. Specific accomplishments and the difficulties encountered are summarized in this report. Most of the effort has gone into complete definition of the PPMT interfaces within the context of today's IT arena: adoption and adherence to the CORBA Component Model (CCM) has yielded a solid architecture basis, and CORBA-related issues (services, specification options, development plans, etc.) have been largely resolved. Implementation goals have been redirected somewhat so as to be more relevant to the upcoming CASSINI flyby of Jupiter, with focus now being more on data analysis and remote sensing retrieval applications.

  5. Phenomenology of Dirac Neutralino Dark Matter

    Energy Technology Data Exchange (ETDEWEB)

    Buckley, Matthew R.; Hooper, Dan; Kumar, Jason

    2013-09-01

    In supersymmetric models with an unbroken R-symmetry (rather than only R-parity), the neutralinos are Dirac fermions rather than Majorana. In this article, we discuss the phenomenology of neutralino dark matter in such models, including the calculation of the thermal relic abundance, and constraints and prospects for direct and indirect searches. Due to the large elastic scattering cross sections with nuclei predicted in R-symmetric models, we are forced to consider a neutralino that is predominantly bino, with very little higgsino mixing. We find a large region of parameter space in which bino-like Dirac neutralinos with masses between 10 and 380 GeV can annihilate through slepton exchange to provide a thermal relic abundance in agreement with the observed cosmological density, without relying on coannihilations or resonant annihilations. The signatures for the indirect detection of Dirac neutralinos are very different than predicted in the Majorana case, with annihilations proceeding dominately to $\\tau^+ \\tau^-$, $\\mu^+ \\mu^-$ and $e^+ e^-$ final states, without the standard chirality suppression. And unlike Majorana dark matter candidates, Dirac neutralinos experience spin-independent scattering with nuclei through vector couplings (via $Z$ and squark exchange), leading to potentially large rates at direct detection experiments. These and other characteristics make Dirac neutralinos potentially interesting within the context of recent direct and indirect detection anomalies. We also discuss the case in which the introduction of a small Majorana mass term breaks the $R$-symmetry, splitting the Dirac neutralino into a pair of nearly degenerate Majorana states.

    2013-01-01

    We review how quark models are able to describe the phenomenology of the charm meson sector. The spectroscopy and decays of charmonium and open charm mesons are described in a particular quark model and compared with the data and the results of other existing models in the literature. A quite reasonable global description of the heavy meson spectra is reached. A new assignment of the $\\psi(4415)$ resonance as a 3D state leaving aside the 4S state to the X(4360) is tested through the analysis of the resonance structure in $e^{+}e^{-}$ exclusive reactions around the $\\psi(4415)$ energy region. We make tentative assignments of some of the $XYZ$ mesons. To elucidate the structure of the $1^{+}$ $c\\bar{s}$ states, i.e. $D_{s1}(2460)$ and $D_{s1}(2536)$, we study the strong decay properties of the $D_{s1}(2536)$ meson. We also perform a calculation of the branching fractions for the semileptonic decays of $B$ and $B_{s}$ mesons into final states containing orbitally excited charmed and charmed-strange mesons, which...

    In the phenomenological relativistic framework of the Dirac equation for spherical nuclei, we use different kinds of single-particle central potentials ({sigma}{sub S}+{sigma}{sub 0}) to investigate certain aspects of the spin and pseudospin (PS) symmetries. Neither the splitting of PS doublets (PSDs) nor the similarity of the radial parts of the small components (F/r) of the corresponding Dirac spinors have been found related with the magnitude of {sigma}{sub S}+{sigma}{sub 0}, in the sense predicted by several authors in the last decade. This conclusion is shown to be valid, in particular, for a potential of Coulomb type. We give a simple explanation for the strong correlation established in the relativistic calculations between the similarity of the radial parts of the big (small) components of the Dirac spinors of two spin (pseudospin) partners and the number of their nodes. The direct effects of the so-called PS symmetry-breaking term (and its singularity point) on the F functions of the PSDs are also analysed. (orig.)

    2014-04-01

    Full Text Available The observation of a scalar resonance at the Large Hadron Collider (LHC, compatible with perturbative electroweak symmetry breaking, reinforces the Standard Model (SM parameterisation of all subatomic data. The logarithmic evolution of the SM gauge and matter parameters suggests that this parameterisation remains viable up to the Planck scale, where gravitational effects are of comparable strength. String theory provides a perturbatively consistent scheme to explore how the parameters of the Standard Model may be determined from a theory of quantum gravity. The free fermionic heterotic string models provide concrete examples of exact string solutions that reproduce the spectrum of the Minimal Supersymmetric Standard Model. Contemporary studies entail the development of methods to classify large classes of models. This led to the discovery of exophobic heterotic-string vacua and the observation of spinor-vector duality, which provides an insight to the global structure of the space of (2,0 heterotic-string vacua. Future directions entail the study of the role of the massive string states in these models and their incorporation in cosmological scenarios. A complementary direction is the formulation of quantum gravity from the principle of manifest phase space duality and the equivalence postulate of quantum mechanics, which suggest that space is compact. The compactness of space, which implies intrinsic regularisation, may be tightly related to the intrinsic finite length scale, implied by string phenomenology.

    One of the most fundamental features of a black hole in general relativity is its event horizon: a boundary from which nothing can escape. There has been a recent surge of interest in the nature of these event horizons and their local neighbourhoods. In an attempt to resolve black hole information paradox(es), and more generally, to better understand the path towards quantum gravity, ‘firewalls’ have been proposed as an alternative to black hole event horizons. In this paper, we explore the phenomenological implications of black holes possessing a surface or ‘firewall’, and predict a potentially detectable signature of these firewalls in the form of a high energy astrophysical neutrino flux. We compute the spectrum of this neutrino flux in different models and show that it is a possible candidate for the source of the PeV neutrinos recently detected by IceCube. This opens up a new area of research, bridging the non-perturbative physics of quantum gravity with the observational black hole and high energy astrophysics.

    2013-07-15

    Using EEG, ECoG, MEG, and microelectrodes to record brain activity is prone to multiple artifacts. The main power line (mains line), video equipment, mechanical vibrations and activities outside the brain are the most common sources of artifacts. MEG amplitudes are low, and even small artifacts distort recordings. In this study, we show how these artifacts can be efficiently removed by recording external cues during MEG recordings. These external cues are subsequently used to register the precise times or spectra of the artifacts. The results indicate that these procedures preserve both the spectra and the time domain wave-shapes of the neuromagnetic signal, while successfully reducing the contribution of the artifacts to the target signals without reducing the rank of the data.

    Full Text Available Neurobehavioral models of personality suggest that the salience assigned to particular classes of stimuli vary as a function of traits that reflect both the activity of neurobiological encoding and relevant social experience. In turn, this joint influence modulates the extent that salience influences attentional processes, and hence learning about and responding to those stimuli. Applying this model to the domain of social valuation, we assessed the differential effects on attentional guidance by affiliative cues of (i a higher-order temperament trait (Social Closeness, and (ii attachment style in a sample of 57 women. Attention to affiliative pictures paired with either incentive or neutral pictures was assessed using camera eye-tracking. Trait social closeness and attachment avoidance interacted to modulate fixation frequency on affiliative but not on incentive pictures, suggesting that both traits influence the salience assigned to affiliative cues specifically.

  14. Cue-Based Feeding in the NICU.

    Science.gov (United States)

    Whetten, Cynthia H

    In NICU settings, caring for neonates born as early as 23 weeks gestation presents unique challenges for caregivers. Traditionally, preterm infants who are learning to orally feed take a predetermined volume of breast milk or formula at scheduled intervals, regardless of their individual ability to coordinate each feeding. Evidence suggests that this volume-driven feeding model should be replaced with a more individualized, developmentally appropriate practice. Evidence from the literature suggests that preterm infants fed via cue-based feeding reach full oral feeding status faster than their volume-feeding counterparts and have shorter lengths of stay in the hospital. Changing practice to infant-driven or cue-based feedings in the hospital setting requires staff education, documentation, and team-based communication.

    Martiny, Kristian Møller Moltke

    2015-01-01

    During recent decades various researchers from health and social sciences have been debating what it means for a person to be disabled. A rather overlooked approach has developed alongside this debate, primarily inspired by the philosophical tradition called phenomenology. This paper develops...... a phenomenological model of disability by arguing for a different methodological and conceptual framework from that used by the existing phenomenological approach. The existing approach is developed from the phenomenology of illness, but the paper illustrates how the case of congenital disabilities, looking...... at the congenital disorder called cerebral palsy (CP), presents a fundamental problem for the approach. In order to understand such congenital cases as CP, the experience of disability is described as being gradually different from, rather than a disruption of, the experience of being abled, and it is argued...

    Introduction: The study examines the effectiveness of antismoking public service announcements (PSAs) among adult smokers as a function of smoking cues and the argument strength of the PSAs. Consistent with the previous cue-reactivity studies, smoking cues are defined as one of the following visual scenes: (a) objects associated with smoking, (b) holding or handling cigarettes, and (c) actual smoking behaviors. Argument strength indicates smoker's judgments of perceived strength and persuasiveness of the arguments extracted from the PSAs. Methods: Data were collected through a web-based experiment of a random sample of general population of smokers (n = 566 adults aged 19 years or older). Each participant was shown 4 PSAs randomly selected from a set of 60. Data were analyzed using multilevel modeling to assess the effects of smoking cues and argument strength. Effectiveness measures include perceived persuasiveness, transportation, valenced thought, negative emotion, and smoking-related thoughts. Results: Argument strength is a significant predictor of outcome variables. Although there were no significant main effects of smoking cues on any outcome variables, smoking cues were found to interact with argument strength such that the association between argument strength and outcome variables became weaker for PSAs in the smoking cue condition compared with those in the no-cue condition. Conclusions: The interaction between smoking cues and argument strength suggests that smoking cues in antismoking PSAs undermine a significant part of what makes PSAs effective—their arguments against smoking. In designing antismoking messages, the inclusion of smoking cues should be weighed carefully. PMID:21330273

    2012-11-01

    The putative role of the lateral parietal lobe in episodic memory has recently become a topic of considerable debate, owing primarily to its consistent activation for studied materials during functional magnetic resonance imaging studies of recognition. Here we examined the performance of patients with parietal lobe lesions using an explicit memory cueing task in which probabilistic cues ("Likely Old" or "Likely New"; 75% validity) preceded the majority of verbal recognition memory probes. Without cues, patients and control participants did not differ in accuracy. However, group differences emerged during the "Likely New" cue condition with controls responding more accurately than parietal patients when these cues were valid (preceding new materials) and trending towards less accuracy when these cues were invalid (preceding old materials). Both effects suggest insufficient integration of external cues into memory judgments on the part of the parietal patients whose cued performance largely resembled performance in the complete absence of cues. Comparison of the parietal patients to a patient group with frontal lobe lesions suggested the pattern was specific to parietal and adjacent area lesions. Overall, the data indicate that parietal lobe patients fail to appropriately incorporate external cues of novelty into recognition attributions. This finding supports a role for the lateral parietal lobe in the adaptive biasing of memory judgments through the integration of external cues and internal memory evidence. We outline the importance of such adaptive biasing through consideration of basic signal detection predictions regarding maximum possible accuracy with and without informative environmental cues.

  8. Viewpoint-independent contextual cueing effect

    Full Text Available We usually perceive things in our surroundings as unchanged despite viewpoint changes caused by self-motion. The visual system therefore must have a function to process objects independently of viewpoint. In this study, we examined whether viewpoint-independent spatial layout can be obtained implicitly. For this purpose, we used a contextual cueing effect, a learning effect of spatial layout in visual search displays known to be an implicit effect. We compared the transfer of the contextual cueing effect between cases with and without self-motion by using visual search displays for 3D objects, which changed according to the participant’s assumed location for viewing the stimuli. The contextual cueing effect was obtained with self-motion but disappeared when the display changed without self-motion. This indicates that there is an implicit learning effect in spatial coordinates and suggests that the spatial representation of object layouts or scenes can be obtained and updated implicitly. We also showed that binocular disparity play an important role in the layout representations.

    Full Text Available Wealth differences between individuals are ubiquitous in modern society, and often serve as the basis for biased social evaluations among adults. The present research probed whether children use cues that are commonly associated with wealth differences in society to guide their consideration of others. In Study 1, 4-5-year-old participants from diverse racial backgrounds expressed preferences for children who were paired with high-wealth cues; White children in Study 1 also matched high-wealth stimuli with White faces. Study 2 conceptually replicated the preference effect from Study 1, and showed that young children (4-6 years also use material wealth indicators to guide their inferences about people's relative standing in other domains (i.e., competence and popularity. Study 3 revealed that children (5-9 years use a broad range of wealth cues to guide their evaluations of, and actions toward, unfamiliar people. Further, biased responses were not attenuated among children whose families were lower in socioeconomic status. Often overlooked by those who study children's attitudes and stereotypes, social class markers appear to influence evaluations, inferences, and behavior early in development.

    1979-03-01

    The effect of both the availability and the quality of visual cues preceding stick-puck contact was investigated for an ice hockey goaltending task. Thirty-four young (15.8 years) goaltenders observed filmed sequences of a hockey player approaching the net and directing a shot to one of the four corners. The film sequences were edited so that 2, 4 or 8 images were occluded prior to the impact of the stick with the puck, reflecting durations of 1/12, 1/6, 1/3 of a second, respectively. The subjects' performances for both the wrist and the slap shot were measured as well as the level of response confidence in both the horizontal and vertical planes. The results indicated that performance precision was aided by the increased availability of pre-shot visual cues. It was also evident that the wrist shot provided more cues for the goaltender than did the slap shot. Performances were found to be superior in the horizontal as compared to the vertical plane. In all dimensions, the subjects' perceptions of their success closely followed the actual performance patterns. It appeared that information that could facilitate anticipation in this goaltending task was both available and useable during the period that precedes the shot.

    2016-05-01

    Encoding multiple cues can improve the accuracy and reliability of navigation and goal localization. Problems may arise, however, if one cue is displaced and provides information which conflicts with other cues. Here we investigated how pigeons cope with cue conflict by training them to locate a goal relative to two landmarks and then varying the amount of conflict between the landmarks. When the amount of conflict was small, pigeons tended to integrate both cues in their search patterns. When the amount of conflict was large, however, pigeons used information from both cues independently. This context-dependent strategy for resolving spatial cue conflict agrees with Bayes optimal calculations for using information from multiple sources.

    The weakly coupled vacuum of E{sub 8} {circle_times} E{sub 8} heterotic string theory remains an attractive scenario for phenomenology and cosmology. The particle spectrum is reviewed and the issues of gauge coupling unification, dilaton stabilization and modular cosmology are discussed. A specific model for condensation and supersymmetry breaking, that respects known constraints from string theory and is phenomenologically viable, is described.

    We present some phenomenology of a new class of intersecting D-brane models. Soft SUSY breaking terms for these models are calculated in the complex structure (u)-moduli dominant SUSY breaking approach (in type IIA). In this case, the dependence of the soft terms on the Yukawas and Wilson lines drops out. These soft terms have a different pattern compared to the usual heterotic string models. Phenomenological implications for dark matter are discussed.

    This paper traces the development of phenomenology as a philosophy originating from the writings of Husserl to its use in phenomenological research and theory development in nursing. The key issues of phenomenological reduction and bracketing are also discussed as they play a pivotal role in the how phenomenological research studies are approached. What has become to be known as "new" phenomenology is also explored and the key differences between it and "traditional" phenomenology are discussed. van Manen's phenomenology is also considered in light of its contemporary popularity among nurse researchers.

    This commentary will apply the notions of constitution and "phenomenological introspection" developed by phenomenology's founder Edmund Husserl to certain themes in Sharon Kaufman's 1988 essay, "Toward a Phenomenology of Boundaries in Medicine: Chronic Illness Experience in the Case of Stroke." The article will discuss how phenomenological analysis can provide important therapeutic insights about the lived experiences of stroke patients and their caregivers, especially as that experience is shaped in the immediate aftermath of a serious stroke. This article will also argue that phenomenology in and by itself is woefully inadequate for producing the kind of self-knowledge and political will needed to produce a socioeconomic environment that reasonably accommodates the needs of stroke patients. The article will end with a brief discussion of how an Eastern, particularly Buddhist, conception of the self is considerably more disability friendly than the one Westerners (phenomenologically) "constitute" and how the former's more realistic understanding of the trajectory of human functioning and its inevitable decline over a lifespan offers a superior platform for developing disability policy and care than its Western counterpart.

  3. Mate choice: from sexual cues to cognitive adaptations.

    Science.gov (United States)

    Miller, G F

    1997-01-01

    Evolutionary psychologists have successfully combined sexual selection theory and empirical research to compile lists of sexual attractiveness cues used in human mate choice. But a list of inputs is not the same as a normative or descriptive model of a psychological adaptation. We need to shift from cataloguing sexual cues to modelling cognitive adaptations for mate choice. This theoretical chapter addresses how to make this transition in three parts. The introduction discusses four general problems with cue cataloguing as an evolutionary psychology research strategy: animals' promiscuous flexibility of cue use; cue use being marginal to cognition; cue use being marginal to the hard game-theoretical aspects of mate choice; and cue use being uninformative about the exact adaptive functions of mate choice. The middle section develops six critiques of current mate choice research: the obsession with sex difference; the over-emphasis on physical rather than behavioural cues; the assumption of weighted linear models of cue integration; the avoidance of game-theoretical problems of mutual choice and assortative mating; the neglect of co-evolution between mate choice heuristics and the cues that they select; and the failure to understand that mate choice is only worth doing if potential mates show significant genetic variance. The conclusion outlines a new normative and descriptive framework for mate choice, centred on the use of brutally efficient search heuristics that exploit the informational structure of human genotypes, phenotypes and populations to make good mate choices.

    Cigarette craving, one hallmark sign of nicotine dependence, is often measured in laboratory settings using cue reactivity methods. How lab measures of cue reactivity relate to real world smoking behavior is unclear, particularly among non-treatment seeking smokers. Within a larger study of hormonal effects on cue reactivity (N=78), we examined the predictive relationship of cue reactivity to smoking, each measured in several ways. Results indicated that cue-evoked craving in response to stressful imagery, and to a lesser extent, in vivo smoking cues, significantly predicted smoking behavior during the week following testing. However, this predictive relationship was absent upon controlling for reactivity to neutral cues. Nicotine dependence may moderate the relationship between cue reactivity and actual smoking, such that this predictive relationship is less robust among highly dependent smokers than among smokers low in nicotine dependence. The question of whether cue-elicited craving predicts smoking among smokers not in treatment is best answered with a qualified yes, depending on how craving is manipulated and measured. Our findings highlight important methodological and theoretical considerations for cue reactivity research.

    Evolutionary psychology suggests that a woman's sexual attractiveness is based on cues of health and reproductive potential. In recent years, research has focused on the ratio of the width of the waist to the width of the hips (the waist-to-hip ratio (WHR). A low WHR (i.e. a curvaceous body) is believed to correspond to the optimal fat distribution for high fertility, and so this shape should be highly attractive.

  8. Human Perception of Ambiguous Inertial Motion Cues

    Science.gov (United States)

    Zhang, Guan-Lu

    2010-01-01

    Human daily activities on Earth involve motions that elicit both tilt and translation components of the head (i.e. gazing and locomotion). With otolith cues alone, tilt and translation can be ambiguous since both motions can potentially displace the otolithic membrane by the same magnitude and direction. Transitions between gravity environments (i.e. Earth, microgravity and lunar) have demonstrated to alter the functions of the vestibular system and exacerbate the ambiguity between tilt and translational motion cues. Symptoms of motion sickness and spatial disorientation can impair human performances during critical mission phases. Specifically, Space Shuttle landing records show that particular cases of tilt-translation illusions have impaired the performance of seasoned commanders. This sensorimotor condition is one of many operational risks that may have dire implications on future human space exploration missions. The neural strategy with which the human central nervous system distinguishes ambiguous inertial motion cues remains the subject of intense research. A prevailing theory in the neuroscience field proposes that the human brain is able to formulate a neural internal model of ambiguous motion cues such that tilt and translation components can be perceptually decomposed in order to elicit the appropriate bodily response. The present work uses this theory, known as the GIF resolution hypothesis, as the framework for experimental hypothesis. Specifically, two novel motion paradigms are employed to validate the neural capacity of ambiguous inertial motion decomposition in ground-based human subjects. The experimental setup involves the Tilt-Translation Sled at Neuroscience Laboratory of NASA JSC. This two degree-of-freedom motion system is able to tilt subjects in the pitch plane and translate the subject along the fore-aft axis. Perception data will be gathered through subject verbal reports. Preliminary analysis of perceptual data does not indicate that

    An experiment is reported in which subjects first heard a list of words and then tried to identify these same words from degraded utterances. Paralleling previous findings in the visual modality, the probability of identifying a given utterance was reduced when the utterance was immediately preceded by other, more degraded, utterances of the same word. A second experiment replicated this "cue-depreciation effect" and in addition found the effect to be weakened, if not eliminated, when the target word was not included in the initial list or when the test was delayed by two days.

  12. Phenomenological sizes of confinement regions in baryons

    Brown, G.E.; Klimt, S.; Weise, W.; Rho, M.

    1988-10-01

    Standard order of magnitude estimates from QCD indicate that the radius of the quark-gluon core in the nucleon is ..lambda../sup -1//sub QCD/ > or approx. 1 fm. However, in work with the chiral bag model, we have found that the effective confinement size for low energy reactions can be as small as approx. = 1/2 fm or smaller. This shrinking of the effective confinement size has been attributed to the pressure of the pion cloud surrounding the quark core. The concept of confinement size is evidently subtle in light-quark systems, due to the chiral vacuum structure. This is indicated by the 'Cheshire Cat' phenomenon, in which physical observables tend to be insensitive to the bag radius R. We suggest that when strange quarks are present, a qualitative change occurs in the Cheshire Cat picture; in particular, we propose that strangeness provides an obstruction to this picture. We present a phenomenological indication that when strange quarks are present, the bag radius R is frozen at a value substantially larger than 0.5 fm by as much as a factor of two. Roughly speaking, the Cheshire Cat picture emerges from a near cancellation between repulsive quark kinetic and attractive pion-cloud energies in the case of the nucleon. In the ..lambda.. and ..sigma.. particles, however, replacement of one up or down quark by a strange quark removes part of the attraction from the coupling of the quarks to the pion cloud. This upsets the balance needed for the Cheshire Cat phenomenon and makes larger strange baryons more favorable energetically than the 0.5 fm ones appropriate for pure u- and d-systems. We find that magnetic moments of strange baryons favor a bag radius R approx. = 1.1 fm. We find that the excited states of the ..lambda..-hyperons favor similarly large bag radii. Somewhat less convincingly, due to perturbative effects - the bag radius appropriate to the ..delta..(1232) lies intermediate between that of the nucleon and of the stran

  14. Reactivity to alcohol cues: isolating the role of perceived availability.

    MacKillop, James; Lisman, Stephen A

    2005-08-01

    Perceived availability of a substance has been proposed to play a role in cue reactivity by both traditional classical conditioning models and S. T. Tiffany's (1990) cognitive processing model (CPM) of substance use. This study investigated the role of availability information on alcohol cue reactivity. Subjects were 134 heavy drinkers in a 2 x 2 between-subjects design, crossing cues (alcohol vs. neutral) and availability information (availability vs. unavailability). The results indicated significant main effects for cue type, with alcohol cues eliciting greater reactivity on multiple measures, and an interaction effect on the Alcohol Urge Questionnaire (M. J. Bohn, D. D. Krahn, & B. B. Staehler, 1995), such that exposure to alcohol cues in conjunction with unavailability information elicited a greater urge. This was largely a result of changes in self-reported craving and was interpreted as consistent with the CPM. Alternative methodologies and limitations are discussed.

  15. Blood cues induce antipredator behavior in Nile tilapia conspecifics.

    Directory of Open Access Journals (Sweden)

    Rodrigo Egydio Barreto

    Full Text Available In this study, we show that the fish Nile tilapia displays an antipredator response to chemical cues present in the blood of conspecifics. This is the first report of alarm response induced by blood-borne chemical cues in fish. There is a body of evidence showing that chemical cues from epidermal 'club' cells elicit an alarm reaction in fish. However, the chemical cues of these 'club' cells are restricted to certain species of fish. Thus, as a parsimonious explanation, we assume that an alarm response to blood cues is a generalized response among animals because it occurs in mammals, birds and protostomian animals. Moreover, our results suggest that researchers must use caution when studying chemically induced alarm reactions because it is difficult to separate club cell cues from traces of blood.

    It has been posited that excessive computer game playing behavior, referred to as computer game addiction, meets criteria that have been internationally established to define drug addiction. Nevertheless, there have been no psychophysiological investigations of the underlying mechanisms available to support the characterization of excessive computer gaming as behavioral addiction. To investigate whether excessive computer gaming parallels learning processes in development and maintenance (which are assumed to underlie drug addiction), the authors obtained a psychophysiological assessment of the (learned) emotional processing of computer game-relevant and -irrelevant cues. For this purpose, electroencephalographic recordings in excessive and casual computer game players were conducted. Significant between-group differences in event-related potentials evoked by computer game related-cues were found at parietal regions and point to an increased emotional processing of these cues in excessive pathological players compared with casual players. These results are in concordance with the suggestion that addiction is characterized and maintained through sensitization of the mesolimbic dopaminergic system along with incentive salience of specific addiction-associated cues.

  17. Phenomenology and the life sciences: Clarifications and complementarities.

    This paper first clarifies phenomenology in ways essential to demonstrating its basic concern with Nature and its recognition of individual and cultural differences as well as commonalities. It furthermore clarifies phenomenological methodology in ways essential to understanding the methodology itself, its purpose, and its consequences. These clarifications show how phenomenology, by hewing to the dynamic realities of life itself and experiences of life itself, counters reductive thinking and "embodiments" of one kind and another. On the basis of these clarifications, the paper then turns to detailing conceptual complementarities between phenomenology and the life sciences, particularly highlighting studies in coordination dynamics. In doing so, it brings to light fundamental relationships such as those between mind and motion and between intrinsic dynamics and primal animation. It furthermore highlights the common concern with origins in both phenomenology and evolutionary biology: the history of how what is present is related to its inception in the past and to its transformations from past to present.

  18. Rigour in phenomenological research: reflections of a novice nurse researcher.

    Pereira, Helder Rocha

    2012-01-01

    This paper is intended to explore conflicts and doubts that novice researchers face when using phenomenological research methods, especially with regard to methodological rigour. There is an increasing interest in different qualitative approaches. The best way to evaluate the quality of qualitative studies has been debated intensively. The great theoretical and methodological diversity of qualitative approaches suggests that a single set of criteria may not be appropriate for all types of research. This is a methodological paper that discusses a personal experience of addressing rigour in a phenomenological study, supported by literature on the topic. Generic qualitative criteria may not be the most adequate to ensure rigour in phenomenological research. The different poles of discussion about the best way to ensure validity of phenomenological research puzzle novice nurse researchers. Focusing on integrative validity that addresses experiential and methodological concerns ensures that researchers will respect the philosophical assumptions underlying a method and allows them to recognise study soundness in the findings and the research process. Phenomenological research must demonstrate methodological congruence and provide meaningful results about lived experiences in a balanced way. Novice researchers need support to understand the articulation between philosophical and methodological foundations that guide the methods they use.

    This paper presents results from an empirical study conducted with a subliminal teaching technique aimed at enhancing learner's performance in Intelligent Systems through the use of physiological sensors. This technique uses carefully designed subliminal cues (positive) and miscues (negative) and projects them under the learner's perceptual visual threshold. A positive cue, called answer cue, is a hint aiming to enhance the learner's inductive reasoning abilities and projected in a way to hel...

  20. Strategy selection in cue-based decision making.

    Science.gov (United States)

    Bryant, David J

    2014-06-01

    People can make use of a range of heuristic and rational, compensatory strategies to perform a multiple-cue judgment task. It has been proposed that people are sensitive to the amount of cognitive effort required to employ decision strategies. Experiment 1 employed a dual-task methodology to investigate whether participants' preference for heuristic versus compensatory decision strategies can be altered by increasing the cognitive demands of the task. As indicated by participants' decision times, a secondary task interfered more with the performance of a heuristic than compensatory decision strategy but did not affect the proportions of participants using either type of strategy. A stimulus set effect suggested that the conjunction of cue salience and cue validity might play a determining role in strategy selection. The results of Experiment 2 indicated that when a perceptually salient cue was also the most valid, the majority of participants preferred a single-cue heuristic strategy. Overall, the results contradict the view that heuristics are more likely to be adopted when a task is made more cognitively demanding. It is argued that people employ 2 learning processes during training, one an associative learning process in which cue-outcome associations are developed by sampling multiple cues, and another that involves the sequential examination of single cues to serve as a basis for a single-cue heuristic.

  1. Cross-language differences in cue use for speech segmentation.

    Two artificial-language learning experiments directly compared English, French, and Dutch listeners' use of suprasegmental cues for continuous-speech segmentation. In both experiments, listeners heard unbroken sequences of consonant-vowel syllables, composed of recurring three- and four-syllable "words." These words were demarcated by (a) no cue other than transitional probabilities induced by their recurrence, (b) a consistent left-edge cue, or (c) a consistent right-edge cue. Experiment 1 examined a vowel lengthening cue. All three listener groups benefited from this cue in right-edge position; none benefited from it in left-edge position. Experiment 2 examined a pitch-movement cue. English listeners used this cue in left-edge position, French listeners used it in right-edge position, and Dutch listeners used it in both positions. These findings are interpreted as evidence of both language-universal and language-specific effects. Final lengthening is a language-universal effect expressing a more general (non-linguistic) mechanism. Pitch movement expresses prominence which has characteristically different placements across languages: typically at right edges in French, but at left edges in English and Dutch. Finally, stress realization in English versus Dutch encourages greater attention to suprasegmental variation by Dutch than by English listeners, allowing Dutch listeners to benefit from an informative pitch-movement cue even in an uncharacteristic position.

    Visual processing is most effective at the location of our attentional focus. It has long been known that various spatial cues can direct visuospatial attention and influence the detection of auditory targets. Cross-modal cueing, however, seems to depend on the type of the visual cue: facilitation...... that the perception of multisensory signals is modulated by a single, supramodal system operating in a top-down manner (Experiment 1). In contrast, bottom-up control of attention, as observed in the exogenous cueing task of Experiment 2, mainly exerts its influence through modality-specific subsystems. Experiment 3...

    In visual working memory (VWM) tasks, participants’ performance can be improved by a retro-object-cue. However, previous studies have not investigated whether participants’ performance can also be improved by a retro-dimension-cue. Three experiments investigated this issue. We used a recall task with a retro-dimension-cue in all experiments. In Experiment 1, we found benefits from retro-dimension-cues compared to neutral cues. This retro-dimension-cue benefit is reflected in an increased probability of reporting the target, but not in the probability of reporting the non-target, as well as increased precision with which this item is remembered. Experiment 2 replicated the retro-dimension-cue benefit and showed that the length of the blank interval after the cue disappeared did not influence recall performance. Experiment 3 replicated the results of Experiment 2 with a lower memory load. Our studies provide evidence that there is a robust retro-dimension-cue benefit in VWM. Participants can use internal attention to flexibly allocate cognitive resources to a particular dimension of memory representations. The results also support the feature-based storing hypothesis.

    Migratory birds use celestial and geomagnetic directional information to orient on their way between breeding and wintering areas. Cue-conflict experiments involving these two orientation cue systems have shown that directional information can be transferred from one system to the other by calibration. We designed experiments with four species of North American songbirds to: (1) examine whether these species calibrate orientation information from one system to the other; and (2) determine whether there are species-specific differences in calibration. Migratory orientation was recorded with two different techniques, cage tests and free-flight release tests, during autumn migration. Cage tests at dusk in the local geomagnetic field revealed species-specific differences: red-eyed vireo, Vireo olivaceus, and northern waterthrush, Seiurus noveboracensis, selected seasonally appropriate southerly directions whereas indigo bunting, Passerina cyanea, and grey catbird, Dumetella carolinensis, oriented towards the sunset direction. When tested in deflected magnetic fields, vireos and waterthrushes responded by shifting their orientation according to the deflection of the magnetic field, but buntings and catbirds failed to show any response to the treatment. In release tests, all four species showed that they had recalibrated their star compass on the basis of the magnetic field they had just experienced in the cage tests. Since release tests were done in the local geomagnetic field it seems clear that once the migratory direction is determined, most likely during the twilight period, the birds use their recalibrated star compass for orientation at departure.

    2014-01-01

    Two visual-world experiments investigated whether and how quickly discourse-based expectations about the prosodic realization of spoken words modulate interpretation of acoustic-prosodic cues. Experiment 1 replicated effects of segmental lengthening on activation of onset-embedded words (e.g. pumpkin) using resynthetic manipulation of duration and fundamental frequency (F0). In Experiment 2, the same materials were preceded by instructions establishing information-structural differences between competing lexical alternatives (i.e. repeated vs. newly-assigned thematic roles) in critical instructions. Eye-movements generated upon hearing the critical target word revealed a significant interaction between information structure and target-word realization: Segmental lengthening and pitch excursion elicited more fixations to the onset-embedded competitor when the target word remained in the same thematic role, but not when its thematic role changed. These results suggest that information structure modulates the interpretation of acoustic-prosodic cues by influencing expectations about fine-grained acoustic-phonetic properties of the unfolding utterance.

  7. Haven't a Cue? Mapping the CUE Space as an Aid to HRA Modeling

    2012-06-01

    Advances in automation present a new modeling environment for the human reliability analysis (HRA) practitioner. Many, if not most, current day HRA methods have their origin in characterizing and quantifying human performance in analog environments where mode awareness and system status indications are potentially less comprehensive, but simpler to comprehend at a glance when compared to advanced presentation systems. The introduction of highly complex automation has the potential to lead to: decreased levels of situation awareness caused by the need for increased monitoring; confusion regarding the often non-obvious causes of automation failures, and emergent system dependencies that formerly may have been uncharacterized. Understanding the relation of incoming cues available to operators during plant upset conditions, in conjunction with operating procedures, yields insight into understanding the nature of the expected operator response in this control room environment. Static systems methods such as fault trees do not contain the appropriate temporal information or necessarily specify the relationship among cues leading to operator response. In this paper, we do not attempt to replace standard performance shaping factors commonly used in HRA nor offer a new HRA method, existing methods may suffice. In this paper we strive to enhance current understanding of the basis for operator response through a technique that can be used during the qualitative portion of the HRA analysis process. The CUE map is a means to visualize the relationship among salient cues in the control room that help influence operator response, show how the cognitive map of the operator changes as information is gained or lost, and is applicable to existing as well as advanced hybrid plants and small modular reactor designs. A brief application involving loss of condensate is presented and advantages and limitations of the modeling approach and use of the CUE map are discussed.

    The vantage perspective from which a memory is retrieved influences the memory's emotional impact, intrusiveness, and phenomenological characteristics. This study tested whether similar effects are observed when participants were instructed to imagine the events from a specific perspective. Fifty student participants listened to a verbal report of car-accidents and visualized the scenery from either a field or observer perspective. There were no between-condition differences in emotionality of memories and the number of intrusions, but imagery experienced from a relative observer perspective was rated as less self-relevant. In contrast to earlier studies on memory retrieval, vantage perspective influenced phenomenological memory characteristics of the memory representation such as sensory details, and ratings of vividness and distancing of the memory. However, vantage perspective is most likely not a stable phenomenological characteristic itself. Implications and suggestions for future research are discussed.

  9. Phenomenology and Sociological Research: The Constitution of “Friendship”

    Directory of Open Access Journals (Sweden)

    Jochen Dreher

    2016-01-01

    Full Text Available This analysis combines phenomenological and sociological research for an investigation of the social relationship of “friendship”. From a phenomenological perspective, it focuses on the epistemological basis, on the subjective constitution of the phenomenon of “friendship”. The social construction of friendship however, is described from a sociological research perspective with reference to concrete empirical expressions of this specific social relationship. The key for the reflections on friendship is the adaptation of Edmund Husserl’s method of phenomenological reduction for the analysis of social phenomena, based on the argumentations of Alfred Schutz and Aron Gurwitsch. This leads to the assumption that friendship is symbolically constituted with reference to everyday transcendent ideas which substantially define the specific expression of this social relationship.

  10. The varieties of ecstasy experience: a phenomenological ethnography.

    Ecstasy (MDMA) has attracted widespread attention with its association as a "recreational substance" that is concentrated in club and rave settings. This paper outlines a phenomenologically grounded ethnographic study of the experiences of ecstasy users in the Sydney, Australia, area. I espouse phenomenology as a framework for describing and understanding these experiences. A number of excerpts are presented from my primary corpus of ethnographic material. For the purposes of this paper I assemble user's reports into nine thematic areas: (1) initial reactions and peaking; (2) the rush; (3) plateau; (4) coming down/scattering; (5) love; (6) peace, love, understanding, and respect; (7) connections on ecstasy; (8) unificatory experiences; (9) returning to baseline. The typical experiences presented in these reports confirm and extend interdisciplinary approaches to understanding ecstasy. I suggest that a context-specific approach that is phenomenologically attuned to user's experiences with ecstasy can contribute to the growing body of literature undertaken in the Australian and international research community.

    Phenomenology was born with the mission to give foundations for science of experience and to open consciousness to scientific study. The influence of phenomenology initiated in the works of Husserl and continued in a wide range of works of others was immense, but mainly within the confines of philosophy and the humanities. The actual attempts to develop a scientific discipline of the study of consciousness and to carry out research on cognition and consciousness were always based on the methods of traditional science in which elimination of the subjective has been always a primary tenet. Thus, focus was mainly on neurological correlates of conscious phenomena. The present paper is an attempt to initiate an extension and revision of phenomenological methodology with the use of philosophical and scientific experience and knowledge accumulated in a century of inquiry and research in relevant disciplines. The question which disciplines are relevant is crucial and our answer is innovative. The range of disciplines involved here is from information science and studies of computation, up to cultural psychology and the studies of philosophical traditions of the East. Concepts related to information and computation studies provide a general conceptual framework free from the limitations of particular languages and of linguistic analysis. This conceptual framework is extending the original perspective of phenomenology to issues of modern technology and science. Cultural psychology gives us tools to root out what in phenomenology was considered universal for humanity, but was a result of European ethnocentrism. Most important here is the contrast between individualistic and collectivistic cultural determinants of consciousness. Finally, philosophical tradition of the East gives alternatives in seeking solutions for fundamental problems. This general outline of the research methodology is illustrated by an example of its use when phenomenology is studied within the conceptual

  12. About the Stimmung. Biranism and phenomenology

    2009-04-01

    Full Text Available M. Richir, in recent works, showed the importance of a phenomenological analysis of the complex relations between “phantasie”, “imagination” and “afectivité” to the deciphering of our too much human nature. The terra incognita that can be seen from that conceptual crossroad is difficult to analyse and poses a challenge: to understand that we can not “measure” our “human condition” without taking into account the imaginative and affective dimensions, the boundaries of reason, the shores of the symbolic institution, the savage non perceptible presence of the Stimmung. In this particular context it is not, in our view, a detail the reference made by Richir to Maine de Biran. The phenomenologist believes Biran to be the philosopher that “better then anyone else, and much before Heidegger”, understood and more rigorously analysed the singular characteristics of that terra incognita (that “lost continent” as Biran puts it of the Stimmung, of the affective tonalities, variations and eruptions. This paper aims to underlain the main points of Richir’s positions on this subject, but also, and most of all, to meditate on that contribution made by Maine de Biran to the understanding of the always bizarre tonality that bathes the world when it appears to us with its Jemeiningkeit.Marc Richir ha mostrado en obras recientes la importancia de un análisis fenomenológico de las relaciones complejas entre fantasía, imaginación y afectividad, a fin de descifrar nuestra “demasiado humana” naturaleza.

    Purpose Febrile status epilepticus (FSE) has been associated with hippocampal injury and subsequent hipppocampal sclerosis (HS) and temporal lobe epilepsy. The FEBSTAT study was designed to prospectively examine the association between prolonged febrile seizures and development of HS and associated temporal lobe epilepsy, one of the most controversial issues in epilepsy. We report on the baseline phenomenology of the final cohorts as well as detailed aims and methodology. Methods The “Consequences of Prolonged Febrile Seizures in Childhood” (FEBSTAT) study is a prospective, multicenter study. Enrolled are children, aged 1 month to 6 years, presenting with a febrile seizure lasting 30 minutes or more based upon ambulance, emergency department, and hospital records, and parental interview. At baseline, procedures included an MRI and EEG done within 72 hours of FSE, and a detailed history and neurological examination. Baseline development and behavior are assessed at one month. The baseline assessment is repeated, with age- appropriate developmental testing at one and five years after enrollment as well as at the development of epilepsy and one year after that. Telephone calls every three months document further seizures. Two other groups of children are included: a ‘control’ group consisting of children with a first febrile seizure ascertained at Columbia University and with almost identical baseline and one year follow-up examinations and a pilot cohort of FSE from Duke University. Key findings The FEBSTAT cohort consists of 199 children with a median age at baseline of 16.0 months (Interquartile range (IQR)=12.0–24.0) and a median duration of FSE of 70.0 minutes (IQR=47.0–110.0). Seizures were continuous in 57.3% and behaviorally intermittent (without recovery in between) in 31.2%; most were partial (4;2.0%) or secondary generalized (65.8%), and almost all (98.0%) culminated in a generalized tonic clonic seizure. Of the 199 children, 86.4% had normal

  14. Preconditioning of Spatial and Auditory Cues: Roles of the Hippocampus, Frontal Cortex, and Cue-Directed Attention

    Directory of Open Access Journals (Sweden)

    Andrew C. Talk

    2016-12-01

    Full Text Available Loss of function of the hippocampus or frontal cortex is associated with reduced performance on memory tasks, in which subjects are incidentally exposed to cues at specific places in the environment and are subsequently asked to recollect the location at which the cue was experienced. Here, we examined the roles of the rodent hippocampus and frontal cortex in cue-directed attention during encoding of memory for the location of a single incidentally experienced cue. During a spatial sensory preconditioning task, rats explored an elevated platform while an auditory cue was incidentally presented at one corner. The opposite corner acted as an unpaired control location. The rats demonstrated recollection of location by avoiding the paired corner after the auditory cue was in turn paired with shock. Damage to either the dorsal hippocampus or the frontal cortex impaired this memory ability. However, we also found that hippocampal lesions enhanced attention directed towards the cue during the encoding phase, while frontal cortical lesions reduced cue-directed attention. These results suggest that the deficit in spatial sensory preconditioning caused by frontal cortical damage may be mediated by inattention to the location of cues during the latent encoding phase, while deficits following hippocampal damage must be related to other mechanisms such as generation of neural plasticity.

    2005-01-01

    Full Text Available Today’s handheld devices are becoming increasingly multifunctional, portable and interactive technospaces which enfold (and unfold an assortment of media forms. This transformation requires a critical approach that considers mobile media as more than telecommunications tools, but also as hybrid new media interfaces. This article presents some initial thoughts pre-empting a larger research project on the phenomenology of mobile media. From a phenomenological perspective, each body-tool relation induces its own technosoma, or specific ways of ‘being-with-equipment’ in a Heideggerian sense; in this conceptual framework, I explore some of the medium specific and intercorporeal effects of the mobile phone.

    Chevin, Luis-Miguel; Lande, Russell

    2015-10-01

    Phenotypically plastic characters may respond to multiple variables in their environment, but the evolutionary consequences of this phenomenon have rarely been addressed theoretically. We model the evolution of linear reaction norms in response to several correlated environmental variables, in a population undergoing stationary environmental fluctuations. At evolutionary equilibrium, the linear combination of environmental variables that acts as a developmental cue for the plastic trait is the multivariate best linear predictor of changes in the optimum. However, the reaction norm with respect to any single environmental variable may exhibit nonintuitive patterns. Apparently maladaptive, or hyperadaptive plasticity can evolve with respect to single environmental variables, and costs of plasticity may increase, rather than reduce, plasticity in response to some variables. We also find conditions for the evolution of an indirect environmental indicator that affects expression of a plastic phenotype, despite not influencing natural selection on it.

    Grasses are traditionally considered as wind pollinated, however, field observations confirmed frequent insect visits to grass flowers, suggesting insect pollination. Fruit and seed predators inflict heavy losses to cereals and millets during their growth, maturation and storage. The actual factors guiding insects and predators to grass flowers, fruits and seeds are not clear. Here, we report attractive blue fluorescence emissions on grass floral parts such as glumes, lemma, palea, lodicules, staminal filaments, pollens and fruits in ultraviolet (UV) 366 nm, whereas the stigmatic portions were not blue, but red fluorescent. We characterized the blue fluorescent constituent in grass reproductive structures as ferulic acid (FA). Fluorescence spectra of blue-emitting grass floral, seed extracts and isolated FA on excitation at 366 nm showed their emissions at 420–460 nm. We propose these FA-based blue fluorescence emissions in grass reproductive structures as visual cues that attract pollinators, predators and even pests towards them. PMID:24061408

    2016-10-07

    The assembly of specialized sub-nuclear microenvironments known as nuclear bodies (NBs) is important for promoting efficient nuclear function. In particular, the Cajal body (CB), a prominent NB that facilitates spliceosomal snRNP biogenesis, assembles in response to genomic cues. Here, we detail the factors that regulate CB assembly and structural maintenance. These include the importance of transcription at nucleating gene loci, the grouping of these genes on human chromosomes 1, 6 and 17, as well as cell cycle and biochemical regulation of CB protein function. We also speculate on the correlation between CB formation and RNA splicing levels in neurons and cancer. The timing and location of these specific molecular events is critical to CB assembly and its contribution to genome function. However, further work is required to explore the emerging biophysical characteristics of CB assembly and the impact upon subsequent genome reorganization.

  4. Boosting Vocabulary Learning by Verbal Cueing During Sleep.

    Schreiner, Thomas; Rasch, Björn

    2015-11-01

    Reactivating memories during sleep by re-exposure to associated memory cues (e.g., odors or sounds) improves memory consolidation. Here, we tested for the first time whether verbal cueing during sleep can improve vocabulary learning. We cued prior learned Dutch words either during non-rapid eye movement sleep (NonREM) or during active or passive waking. Re-exposure to Dutch words during sleep improved later memory for the German translation of the cued words when compared with uncued words. Recall of uncued words was similar to an additional group receiving no verbal cues during sleep. Furthermore, verbal cueing failed to improve memory during active and passive waking. High-density electroencephalographic recordings revealed that successful verbal cueing during NonREM sleep is associated with a pronounced frontal negativity in event-related potentials, a higher frequency of frontal slow waves as well as a cueing-related increase in right frontal and left parietal oscillatory theta power. Our results indicate that verbal cues presented during NonREM sleep reactivate associated memories, and facilitate later recall of foreign vocabulary without impairing ongoing consolidation processes. Likewise, our oscillatory analysis suggests that both sleep-specific slow waves as well as theta oscillations (typically associated with successful memory encoding during wakefulness) might be involved in strengthening memories by cueing during sleep.

    Emerging research suggests potential effects of the menstrual cycle on various aspects of smoking behavior in women, but results to date have been mixed. The present study sought to explore the influence of menstrual cycle phase on reactivity to smoking in vivo and stressful imagery cues in a sample of non-treatment-seeking women smokers. Via a within-subjects design, nicotine-dependent women (N = 37) participated in a series of four cue reactivity sessions, each during a distinct biologically verified phase of the menstrual cycle (early follicular [EF], mid-follicular [MF], mid-luteal [ML], and late luteal [LL]). Subjective (Questionnaire of Smoking Urges-Brief; QSU-B) and physiological (skin conductance and heart rate) measures of craving and reactivity were collected and compared across phases. Subjective reactive craving (QSU-B) to smoking in vivo cues varied significantly across the menstrual cycle (p = .02) and was higher in both EF and MF phases versus ML and LL phases, but this finding was not sustained when controlling for reactivity to neutral cues. Heart rate reactivity to stressful imagery cues (p = .01) and skin conductance reactivity to smoking in vivo cues (p = .05) varied significantly across the menstrual cycle upon controlling for reactivity to neutral cues, with highest reactivity during the MF phase. Menstrual cycle phase may have an effect on reactivity to smoking-related and stressful cues among women smokers. These findings contribute to an expanding literature, suggesting menstrual cycle effects on smoking behaviors in women.

  10. Isolation of Binocular Cues for Motion in Depth

    Full Text Available There are two binocular cues of motion in depth: the interocular velocity difference (IOVD and changing disparity over time (CDOT. Psychophysical evidence for the contribution to perceiving motion in depth has been accumulated for both of the two cues, using techniques to isolate each cue. However, no study estimated seriously how reliably each cue is isolated in the techniques. In this study, we apply a model of motion in depth to estimate how each type of stimuli isolates each of IOVD and CDOT cues. The model consists of the motion energy and the disparity energy detectors as subunits and adds their outputs to built the IOVD and CDOT detectors. Simulations show that some, but not all of stimuli used in the literature are appropriate for isolating cues. The temporally uncorrelated randomdot stereogram isolates CDOT cue and the binocularly uncorrelated randomdot kinematogram isolates IOVD cues. However, temporally anticorreated version of randomdot stereogram has influence of reverse motion components of IOVD and binocularly anticorreated version of randomdot kinematogram has influence of reverse motion components of CDOT. Gratings with opposite orientation between the eyes are also good for isolation of IOVD. We performed psychophysical experiments to examine the plausibility of the model prediction.

    Individuals who play Internet games excessively show elevated brain reactivity to game-related cues. This study attempted to test whether this elevated cue reactivity observed in game players is a result of repeated exposure to Internet games. Healthy young adults without a history of excessively playing Internet games were recruited, and they were instructed to play an online Internet game for 2 hours/day for five consecutive weekdays. Two control groups were used: the drama group, which viewed a fantasy TV drama, and the no-exposure group, which received no systematic exposure. All participants performed a cue reactivity task with game, drama, and neutral cues in the brain scanner, both before and after the exposure sessions. The game group showed an increased reactivity to game cues in the right ventrolateral prefrontal cortex (VLPFC). The degree of VLPFC activation increase was positively correlated with the self-reported increase in desire for the game. The drama group showed an increased cue reactivity in response to the presentation of drama cues in the caudate, posterior cingulate, and precuneus. The results indicate that exposure to either Internet games or TV dramas elevates the reactivity to visual cues associated with the particular exposure. The exact elevation patterns, however, appear to differ depending on the type of media experienced. How changes in each of the regions contribute to the progression to pathological craving warrants a future longitudinal study.

    The development of addiction is marked by a pathological associative learning process that imbues incentive salience to stimuli associated with drug use. Recent efforts to treat addiction have targeted this learning process using cue exposure therapy augmented with d-cycloserine (DCS), a glutamatergic agent hypothesized to enhance extinction learning. To better understand the impact of DCS-facilitated extinction on neural reactivity to drug cues, the present study reports fMRI findings from a randomized, double-blind, placebo-controlled trial of DCS-facilitated cue exposure for cocaine dependence. Twenty-five participants completed two MRI sessions (before and after intervention), with a cocaine-cue reactivity fMRI task. The intervention consisted of 50mg of DCS or placebo, combined with two sessions of cocaine cue exposure and skills training. Participants demonstrated cocaine cue activation in a variety of brain regions at baseline. From the pre- to post-study scan, participants experienced decreased activation to cues in a number of regions (e.g., accumbens, caudate, frontal poles). Unexpectedly, placebo participants experienced decreases in activation to cues in the left angular and middle temporal gyri and the lateral occipital cortex, while DCS participants did not. Three trials of DCS-facilitated cue exposure therapy for cocaine dependence have found that DCS either increases or does not significantly impact response to cocaine cues. The present study adds to this literature by demonstrating that DCS may prevent extinction to cocaine cues in temporal and occipital brain regions. Although consistent with past research, results from the present study should be considered preliminary until replicated in larger samples. Copyright © 2013 Elsevier Ireland Ltd.

  16. Speaker's voice as a memory cue.

    Campeanu, Sandra; Craik, Fergus I M; Alain, Claude

    2015-02-01

    Speaker's voice occupies a central role as the cornerstone of auditory social interaction. Here, we review the evidence suggesting that speaker's voice constitutes an integral context cue in auditory memory. Investigation into the nature of voice representation as a memory cue is essential to understanding auditory memory and the neural correlates which underlie it. Evidence from behavioral and electrophysiological studies suggest that while specific voice reinstatement (i.e., same speaker) often appears to facilitate word memory even without attention to voice at study, the presence of a partial benefit of similar voices between study and test is less clear. In terms of explicit memory experiments utilizing unfamiliar voices, encoding methods appear to play a pivotal role. Voice congruency effects have been found when voice is specifically attended at study (i.e., when relatively shallow, perceptual encoding takes place). These behavioral findings coincide with neural indices of memory performance such as the parietal old/new recollection effect and the late right frontal effect. The former distinguishes between correctly identified old words and correctly identified new words, and reflects voice congruency only when voice is attended at study. Characterization of the latter likely depends upon voice memory, rather than word memory. There is also evidence to suggest that voice effects can be found in implicit memory paradigms. However, the presence of voice effects appears to depend greatly on the task employed. Using a word identification task, perceptual similarity between study and test conditions is, like for explicit memory tests, crucial. In addition, the type of noise employed appears to have a differential effect. While voice effects have been observed when white noise is used at both study and test, using multi-talker babble does not confer the same results. In terms of neuroimaging research modulations, characterization of an implicit memory effect

    Occlusion boundaries and junctions provide important cues for inferring three-dimensional scene organization from two-dimensional images. Although several investigators in machine vision have developed algorithms for detecting occlusions and other edges in natural images, relatively few psychophysics or neurophysiology studies have investigated what features are used by the visual system to detect natural occlusions. In this study, we addressed this question using a psychophysical experiment where subjects discriminated image patches containing occlusions from patches containing surfaces. Image patches were drawn from a novel occlusion database containing labeled occlusion boundaries and textured surfaces in a variety of natural scenes. Consistent with related previous work, we found that relatively large image patches were needed to attain reliable performance, suggesting that human subjects integrate complex information over a large spatial region to detect natural occlusions. By defining machine observers using a set of previously studied features measured from natural occlusions and surfaces, we demonstrate that simple features defined at the spatial scale of the image patch are insufficient to account for human performance in the task. To define machine observers using a more biologically plausible multiscale feature set, we trained standard linear and neural network classifiers on the rectified outputs of a Gabor filter bank applied to the image patches. We found that simple linear classifiers could not match human performance, while a neural network classifier combining filter information across location and spatial scale compared well. These results demonstrate the importance of combining a variety of cues defined at multiple spatial scales for detecting natural occlusions. PMID:23255731

  18. Distinguishing Reconfiguration and Compound-cue Retrieval in Task Switching

    Directory of Open Access Journals (Sweden)

    Gordon D Logan

    2010-10-01

    Full Text Available Many researchers claim that task switching requires reconfiguration of the cognitive system. Others claim that task switching involves cue-based memory retrieval processes and not reconfiguration. We evaluate these competing claims by developing both reconfiguration and cue-based memory models in a common theoretical framework and by fitting the models to' target functions', which show how performance on individual target stimuli varies depending on the task subjects perform on the targets. Our analyses show that the process of compound-cue retrieval – using the task cue and the target as joint retrieval cues to select a response from memory – is sufficient to explain target functions for parity and magnitude judgments of digits and that reconfiguration does not seem to add anything to the explanation. We address the generality of this conclusion and speculate about the conditions under which reconfiguration may be necessary for task switching.

    D-cycloserine (DCS), a partial glutamate N-methyl-D-aspartic acid (NMDA) receptor agonist, enhances extinction of conditioned fear responding in rodents and facilitates exposure-based learning in humans with anxiety disorders. This preliminary study investigates DCS pretreatment on response to cocaine cues in cocaine-dependent subjects. Ten cocaine-dependent subjects were randomly assigned to receive either 50 mg DCS or matching placebo two hours before each of two 1-hour cocaine cue exposure sessions one day apart. HR and craving ratings were obtained before and during cue exposure sessions. There was a trend towards increased craving to cocaine cues in cocaine-dependent individuals after administration of DCS. The administration of DCS prior to cue exposure sessions may facilitate response activation. While facilitation of extinction-based learning by DCS may have therapeutic potential for cocaine dependence, this drug may exhibit a different profile in cocaine-dependent individuals as compared to those with anxiety disorders.

    2011-01-01

    This study examines the identity cues that family caregivers and healthcare personnel use with seniors living with dementia and living in nursing homes. The identity cues represent biographical knowledge used to stimulate the dementia sufferer, trigger signals and incite interaction. Our grounded approach hinges on three objectives: to identify and categorize identity cues; to document their uses; and to gain a better understanding of their effectiveness. We interviewed nine family caregivers and 12 healthcare workers. Qualitative data indicates that the participants use identity cues that evoke seniors' sociological, relational and individual characteristics. These identity cues play a central role in communication and constitute important information that the family caregivers can share with healthcare personnel. They sustain memory, facilitate care and reinforce seniors' self-value. These results help to define identity, foster a greater role for family caregivers, and constitute a sound basis for the implementation of personalized interventions.

    Repeated visual context induces higher search efficiency, revealing a contextual cueing effect, which depends on the association between the target and its visual context. In this study, participants performed a visual search task where search items were presented with depth information defined by binocular disparity. When the 3-dimensional (3D) configurations were repeated over blocks, the contextual cueing effect was obtained (Experiment 1). When depth information was in chaos over repeated configurations, visual search was not facilitated and the contextual cueing effect largely crippled (Experiment 2). However, when we made the search items within a tiny random displacement in the 2-dimentional (2D) plane but maintained the depth information constant, the contextual cueing was preserved (Experiment 3). We concluded that the contextual cueing effect was robust in the context provided by 3D space with stereoscopic information, and more importantly, the visual system prioritized stereoscopic information in learning of spatial information when depth information was available.

    A review of the literature pertinent to cue exposure treatment in alcohol dependence is presented. Psychological models of relapse, based on conditioning and social learning theories, are critically evaluated. In particular, attention is drawn to the potential implications for cue exposure research and treatment of an interaction between Pavlovian and operant conditioning, problems with the application of the concepts of arousal and craving and the importance of a systems model to understand physiological responses. It is concluded that no study has so far demonstrated a link between conditioned responses to alcohol-related cues and relapse, an assumption on which cue exposure treatment is based. Further, the evidence for the effectiveness of cue exposure as a treatment is lacking. Promising research directions are identified.

    Plant-feeding insects use visual and olfactory cues (shape, color, plant volatiles) for host location, but the relative importance of different cues and interactions with non-host-plant volatiles in ecosystems of varying plant biodiversity is unclear for most species. We studied invasive bark beetles and wood borers associated with pine trees to characterize interactions among color, host and non-host volatiles, by employing traps that mimic tree trunks. Cross-vane flight intercept traps (black, green, red, white, yellow, clear) and black funnel traps were used with and without attractants (α-pinene + ethanol), repellents (non-host green leaf volatiles, 'GLV'), and attractant/repellent combinations in four pine forests in New Zealand. We trapped 274,594 Hylurgus ligniperda, 7842 Hylastes ater, and 16,301 Arhopalus ferus. Trap color, attractant, and color × attractant effects were highly significant. Overall, black and red traps had the highest catches, irrespective of the presence of attractants. Alpha-pinene plus ethanol increased trap catch of H. ligniperda 200-fold but only 6-fold for H. ater and 2-fold for A. ferus. Green leaf volatiles had a substantial repellent effect on trap catch of H. ligniperda but less on H. ater and A. ferus. Attack by H. ligniperda was halved when logs were treated with GLV, and a similar effect was observed when logs were placed among broadleaved understory shrubs emitting GLV. Overall, H. ligniperda was most strongly affected by the olfactory cues used, whereas H. ater and A. ferus were more strongly affected by visual cues. Collectively, the results support the semiochemical diversity hypothesis, indicating that non-host plant volatiles from diverse plant communities or artificial dispensers can contribute to resistance against herbivores by partly disrupting host location.

  12. How to develop a phenomenological model of disability.

    Science.gov (United States)

    Martiny, Kristian Moltke

    2015-11-01

    During recent decades various researchers from health and social sciences have been debating what it means for a person to be disabled. A rather overlooked approach has developed alongside this debate, primarily inspired by the philosophical tradition called phenomenology. This paper develops a phenomenological model of disability by arguing for a different methodological and conceptual framework from that used by the existing phenomenological approach. The existing approach is developed from the phenomenology of illness, but the paper illustrates how the case of congenital disabilities, looking at the congenital disorder called cerebral palsy (CP), presents a fundamental problem for the approach. In order to understand such congenital cases as CP, the experience of disability is described as being gradually different from, rather than a disruption of, the experience of being abled, and it is argued that the experience of disability is complex and dynamically influenced by both intrinsic and extrinsic factors. Different experiential aspects of disability- pre-reflective, attuned and reflective aspects-are described, demonstrating that the experience of disability comes in different degrees. Overall, this paper contributes to the debates about disability by further describing the personal aspects and experience of persons living with disabilities.

  20. Perceptual Anomalies in Schizophrenia: Integrating Phenomenology and Cognitive Neuroscience

    Science.gov (United States)

    Uhlhaas, Peter J.; Mishara, Aaron L.

    2007-01-01

    From phenomenological and experimental perspectives, research in schizophrenia has emphasized deficits in “higher” cognitive functions, including attention, executive function, as well as memory. In contrast, general consensus has viewed dysfunctions in basic perceptual processes to be relatively unimportant in the explanation of more complex aspects of the disorder, including changes in self-experience and the development of symptoms such as delusions. We present evidence from phenomenology and cognitive neuroscience that changes in the perceptual field in schizophrenia may represent a core impairment. After introducing the phenomenological approach to perception (Husserl, the Gestalt School), we discuss the views of Paul Matussek, Klaus Conrad, Ludwig Binswanger, and Wolfgang Blankenburg on perception in schizophrenia. These 4 psychiatrists describe changes in perception and automatic processes that are related to the altered experience of self. The altered self-experience, in turn, may be responsible for the emergence of delusions. The phenomenological data are compatible with current research that conceptualizes dysfunctions in perceptual processing as a deficit in the ability to combine stimulus elements into coherent object representations. Relationships of deficits in perceptual organization to cognitive and social dysfunction as well as the possible neurobiological mechanisms are discussed. PMID:17118973

    In the context of flux compactifications, metastable vacua with a small positive cosmological constant are obtained by combining a sector where supersymmetry is broken dynamically with the sector responsible for moduli stabilization, which is known as the F-uplifting. We analyze this procedure in a model-independent way and study phenomenological properties of the resulting vacua.
