Solar prominences

Engvold, Oddbjørn

2015-01-01

This volume presents the latest research results on solar prominences, including new developments on e.g. chirality, fine structure, magnetism, diagnostic tools and relevant solar plasma physics. In 1875 solar prominences, as seen out of the solar limb, were described by P.A. Secchi in his book Le Soleil as "gigantic pink or peach-flower coloured flames". The development of spectroscopy, coronagraphy and polarimetry brought tremendous observational advances in the twentieth century. The authors present and discuss exciting new challenges (resulting from observations made by space and ground-based telescopes in the 1990s and the first decade of the 21st century) concerning the diagnostics of prominences, their formation, their life time and their eruption along with their impact in the heliosphere (including the Earth). The book starts with a general introduction of the prominence “object” with some historical background on observations and instrumentation. In the next chapter, the various forms of promine...

The Manhattan Project and its Effects on American Women Scientists

Fletcher, Samuel

2008-04-01

There have been many detailed historical accounts of the Manhattan Project, but few have recognized the technical role women scientists and engineers crucially played in the Project's success. Despite their absence from these prominent accounts, recent studies have revealed that, in fact, women participated in every non-combat operation associated with the Manhattan Project. With such extensive participation of women and such a former lack of historical attention upon them, little analysis has been done on how the Manhattan Project might have influenced the prospectus of women scientists after the war. This talk has two aims: 1) to recount some of the technical and scientific contributions of women to the Manhattan Project, and 2) to examine what effects these contributions had on the women's careers as scientists. In other words, I intend offer a preliminary explanation of the extent to which the Manhattan Project acted both as a boon and as a detriment to American women scientists. And finally, I will address what this historical analysis could imply about the effects of current efforts to recruit women into science.

The work of Daphne Hampson: The God talk of one feminist theologian

Directory of Open Access Journals (Sweden)

Maretha M. Jacobs

2007-05-01

Full Text Available For almost all of human history both in ancient times and in modern contexts, talk about God has been mainly a male preserve. So closely has male God talk been associated by many with God’s own voice, that it is still not commonly realized and acknowledged. With the rise of feminism, especially during recent decades, it has changed. In this article the work of Daphne Hampson, a British feminist theologian, is considered: Her definition and critique of Christianity, her view of the relation between the present and our Christian past, specifically with regard to God talk, her dealing with prominent aspects of the Christian belief system and her emphasis on taking seriously all available knowledge and our contemporary context in doing theology. In line with some current trends in God talk, such as a movement away from anthropomorphism, and in dialogue with Friedrich Schleiermacher, she formulates what she calls a “future theism”.

Formation and support of prominence

International Nuclear Information System (INIS)

Forbes, T.G.

1986-01-01

A short introduction is given to the concepts discussed by the group on the formation and support of prominences. Only quiescent and long-lived active region prominences were considered, since transient prominence phenomena, such as sprays, surges, H alpha flare-loops, and coronal rain, are dynamically distinct from long-lived, prominences. Stable prominences (which are often referred to as filaments when seen against the disk) can be subdivided into three categories, namely active region prominences, quiescent prominences and polar crown prominences. The third category is closely related to the second since a quiescent prominence will eventually evolve into a polar crown prominence if it lasts long enough. The distinction between the first and second categories is not sharp either since intermediates exist here as well (Martin, 1973)

Apparent Solar Tornado-Like Prominences

Panasenco, Olga; Martin, Sara F.; Velli, Marco

2014-02-01

Recent high-resolution observations from the Solar Dynamics Observatory (SDO) have reawakened interest in the old and fascinating phenomenon of solar tornado-like prominences. This class of prominences was first introduced by Pettit ( Astrophys. J. 76, 9, 1932), who studied them over many years. Observations of tornado prominences similar to the ones seen by SDO had already been documented by Secchi ( Le Soleil, 1877). High-resolution and high-cadence multiwavelength data obtained by SDO reveal that the tornado-like appearance of these prominences is mainly an illusion due to projection effects. We discuss two different cases where prominences on the limb might appear to have a tornado-like behavior. One case of apparent vortical motions in prominence spines and barbs arises from the (mostly) 2D counterstreaming plasma motion along the prominence spine and barbs together with oscillations along individual threads. The other case of apparent rotational motion is observed in a prominence cavity and results from the 3D plasma motion along the writhed magnetic fields inside and along the prominence cavity as seen projected on the limb. Thus, the "tornado" impression results either from counterstreaming and oscillations or from the projection on the plane of the sky of plasma motion along magnetic-field lines, rather than from a true vortical motion around an (apparent) vertical or horizontal axis. We discuss the link between tornado-like prominences, filament barbs, and photospheric vortices at their base.

Re-interpreting Prominences Classified as Tornadoes

Martin, Sara F.; Venkataramanasastry, Aparna

Some papers in the recent literature identify tornado prominences with barbs of quiescent prominences while papers in the much older historic literature include a second category of tornado prominence that does not correspond to a barb of a quiescent prominence. The latter are described as prominence mass rotating around a nearly vertical axis prior to its eruption and the rotation was verified by spectral measurements. From H alpha Doppler-shifted mass motions recorded at Helio Research or the Dutch Open Telescope, we illustrate how the apparent tornado-like motions, identified with barbs, are illusions in our mind’s eye resulting from poorly resolved counterstreaming threads of mass in the barbs of quiescent prominences. In contrast, we confirm the second category of rotational motion in prominences shortly before and during eruption. In addition, we identify this second category as part of the late phase of a phenomenon called the roll effect in erupting prominences. In these cases, the eruption begins with the sideways rolling of the top of a prominence. As the eruption proceeds the rolling motion propagates down one leg or both legs of the prominence depending on whether the eruption is asymmetric or symmetric respectively. As an asymmetric eruption continues, the longer lasting leg becomes nearly vertical and its rotational motion also continues. If only this phase of the eruption was observed, as in some historic cases, it was called a tornado prominence. However, when we now observe entire eruptions in time-lapse sequences, the similarity to terrestrial tornadoes is lost. We conclude that neither prominence barbs, that give the illusion of rotation, nor the cases of true rotational motion, in the legs of erupting prominences, are usefully described as tornado prominences when the complete prominence structure or complete erupting event is observed.

A prevalent but untested paradigm is often used to describe the prominence-cavity system: the cavity is under-dense because it is evacuated by supplying mass to the condensed prominence. The thermal non-equilibrium (TNE) model of prominence formation offers a theoretical framework to predict the thermodynamic evolution of the prominence and the surrounding corona. We examine the evidence for a prominence-cavity connection by comparing the TNE model with diagnostics of dynamic extreme ultraviolet (EUV) emission surrounding the prominence, specifically prominence horns. Horns are correlated extensions of prominence plasma and coronal plasma which appear to connect the prominence and cavity. The TNE model predicts that large-scale brightenings will occur in the Solar Dynamics Observatory Atmospheric Imaging Assembly 171 Å bandpass near the prominence that are associated with the cooling phase of condensation formation. In our simulations, variations in the magnitude of footpoint heating lead to variations in the duration, spatial scale, and temporal offset between emission enhancements in the other EUV bandpasses. While these predictions match well a subset of the horn observations, the range of variations in the observed structures is not captured by the model. We discuss the implications of our one-dimensional loop simulations for the three-dimensional time-averaged equilibrium in the prominence and the cavity. Evidence suggests that horns are likely caused by condensing prominence plasma, but the larger question of whether this process produces a density-depleted cavity requires a more tightly constrained model of heating and better knowledge of the associated magnetic structure.

Talking about the job: The influence of management on leadership discourses Over the past decades, much research has been carried out to detail and analyse the uneven distribution of men and women in management positions (Acker 1990; Billing and Alvesson 2000; Österlind and Haake 2010). In Denmark......, this has been visible in banks and building societies where men would occupy the vast majority of senior positions, and women would be predominant in lower-ranking jobs, making it extremely difficult to climb the career ladder (Ellehave and Søndergaard 2006; Holmgreen 2009; Strunck 2013). One...... of the reasons for this is that gender inequalities continue to exist because they are deeply embedded in social structures and organisational processes, and not least upheld by the male managers whose positions are challenged by women’s entry into management (Schein 2007). In studies, this is referred...

I am a primary health care (PHC) coordinator working with the May Day Rural project, a local NGO involved in integrated approaches and programs with rural communities in the Ga District of the Greater-Accra region in Ghana. When we talk about the community development approach we must first and foremost recognize that we are talking about women, because in the developing world frequent childbirths mean that her burden of mortality is higher than a man's; her workload is extremely heavy--whether in gardening, farming, other household duties, caring for the sick, or the rearing of children; she has a key role in PHC and community development, because men are always looking for greener pastures elsewhere, leaving the women behind. Women's concerns are critical in most health care projects and women and children are their main beneficiaries. Why not include women in the management team, project design, implementation and evaluation processes? That is what the May Day Rural project is practicing, encouraging women's participation and creating a relationship of trust. full text

A three-dimensional model for solar prominences

International Nuclear Information System (INIS)

Demoulin, P.; Priest, E.R.; Anzer, U.

1989-01-01

Prominences have been modelled largely as one-or two-dimensional structures, and yet observations show them to possess important variations in the third dimension along the prominence axis with great arches with feet reaching down towards the solar surface. As an initial attempt to understand this structure we consider a three-dimensional linear force-free field model for the global magnetic field around a quiescent prominence. It consists of a fundamental together with a harmonic that is periodic along the prominence. At the solar surface there is a series of flux concentrations spaced out periodically on both sides of the prominence. Between a pair of oppositely directed flux concentration, the magnetic field in the prominence is stronger and tends to be less highly sheared than elsewhere. This modulation of the field strength and shear angle along the prominence decreases with height and almost disappears above 10 Mm. Prominence fields that increase with height occur when the shear is large and the length-scale for field variations perpendicular to the prominence exceeds that along it. The variation of the prominence height along the prominence is calculated and it is suggested that feet occur where the prominence sags down to low heights. For prominences of Normal polarity this tends to occur near supergranule centres where the transverse field is least, whereas for those of Inverse polarity it usually takes place near the chromospheric network where the transverse field is greatest. The effect of concentrating the base flux by including extra harmonics is also included. For Normal polarity prominences it tends to make the foot wider, and for Inverse polarity configurations, it usually creates deeper and narrower feet

We use the detailed 3D whole-prominence fine structure model to produce the first simulated high-resolution ALMA observations of a modeled quiescent solar prominence. The maps of synthetic brightness temperature and optical thickness shown in the present paper are produced using a visualization method for synthesis of the submillimeter/millimeter radio continua. We have obtained the simulated observations of both the prominence at the limb and the filament on the disk at wavelengths covering a broad range that encompasses the full potential of ALMA. We demonstrate here extent to which the small-scale and large-scale prominence and filament structures will be visible in the ALMA observations spanning both the optically thin and thick regimes. We analyze the relationship between the brightness and kinetic temperature of the prominence plasma. We also illustrate the opportunities ALMA will provide for studying the thermal structure of the prominence plasma from the cores of the cool prominence fine structure to the prominence–corona transition region. In addition, we show that detailed 3D modeling of entire prominences with their numerous fine structures will be important for the correct interpretation of future ALMA observations of prominences.

Talking About Antismoking Campaigns: What Do Smokers Talk About, and How Does Talk Influence Campaign Effectiveness?

Campaign-stimulated conversations have been shown to increase the effectiveness of antismoking campaigns. In order to explore why such effects occur, in the current study we coded the content of naturally occurring conversations. We also examined whether the short-term effects of talking, and of different types of talk, on quitting intentions were mediated through intrapersonal message responses. Using the Natural Exposure(SM) methodology, we exposed 411 smokers to 1 of 6 antismoking advertisements while they were watching television at home. Responses to the advertisement-conversation participation and content, emotional responses, personalized perceived effectiveness, and changes in intentions to quit-were measured within 3 days of exposure. Conversations were coded for appraisal of the advertisement (favorable, neutral, or unfavorable) and the presence of quitting talk and emotion talk. Mediation analyses indicated that the positive effects of talking on intention change were mediated through personalized perceived effectiveness and that the positive effects were driven by conversations that contained a favorable appraisal and/or quitting talk. Conversely, conversations that contained an unfavorable appraisal of the advertisement were negatively associated with campaign effectiveness. These findings highlight the importance of measuring interpersonal communication when evaluating campaigns and the need for further research to identify the message characteristics that predict when smokers talk and when they talk only in desirable ways.

Recent observations of prominences obtained with high spatial and temporal resolution instruments, on board satellites (Hinode, SDO) as well as on the ground (SST) have provided very intriguing movies and open a new area for understanding the nature of prominences. The main topics are still debate: formation, dynamics, and characteristics of the plasma in the core and in the transition zone between the prominence and corona. We will review briefly the recent advances made in these topics, observationally as well as theoretically.

Then and Now: Women Respond to the Manhattan Project - an illustrated talk

Fermi, M. A., Olivia

I am very much looking forward to visiting you, the family of physicists gathering for your annual APS conference. In different ways, my grandfather Enrico Fermi is a member of both our families. In this sense we are connected and share a common legacy, which I want to explore from the angle of two women inextricably involved with and affected by the Manhattan Project. One from the past and one alive now. These two women, despite a significant temporal and cultural gap share a remarkable number of traits and values. My talk will not offer a particular thesis or finding. Rather it will be about ways of seeing, including questioning unnoticed assumptions and belief systems. My grandmother Laura Fermi, modeled this for me as a youngster. She was at Enrico's side during the Manhattan Project years, yet in the dark about his work. What was it like to live in a climate of intellectually and patriotically charged enthusiasm, with an undercurrent of unspoken dread? Laura, just like most everyone else, discovered the true nature of the effort on the day the atomic bomb was dropped on Hiroshima. After the war and after Enrico's untimely death in 1954, in response to all she had experienced, Laura re-invented herself as an author and visionary, pioneering in both the environmental and handgun control movements. Marian Naranjo lives on the Santa Clara Pueblo near Los Alamos. Her ancestors dwelled on the Pajarito Plateau which encompasses the space where Los Alamos National Labs (LANL) is today. Her people, the Pueblo People have used the area's natural resources for ceremonial and survival for uncountable generations. They say, ``We are this place.'' What is it like to live on land one's families have safely occupied for thousands of years, with an undercurrent of dread at the prospect of toxic waste stream products from LANL? Like my grandmother did in her place and time, Marian builds community as an integral part of her environmental and social justice activism. She is

Head turning as a prominent motor symptom in status epilepticus.

Head and eye turning is frequently observed during seizures. Versions with tonic and/or clonic symptoms can be differentiated from smooth head deviations. Head turning as a prominent symptom of status epilepticus has not previously been reported. We present eight case reports, (7 women/1 man, mean age 41 years, median 41.5, range 10 to 74), of status epilepticus (SE), with head turning as a prominent motor symptom. Six were accompanied by continuous frontal, occipital and temporal ictal epileptiform discharges. Furthermore, two patients had absence status with rhythmic and clonic head versions. While the localizing significance of head turnings in SE is low, in our cases, the direction was away from the discharging hemisphere in all cases of focal SE regardless of whether the turning was classified as version (three cases) or deviation (three cases). In this small series of SE, the classical observation of a patient looking away from the discharging hemisphere is still valid.

TANGLED MAGNETIC FIELDS IN SOLAR PROMINENCES

International Nuclear Information System (INIS)

Van Ballegooijen, A. A.; Cranmer, S. R.

2010-01-01

Solar prominences are an important tool for studying the structure and evolution of the coronal magnetic field. Here we consider so-called hedgerow prominences, which consist of thin vertical threads. We explore the possibility that such prominences are supported by tangled magnetic fields. A variety of different approaches are used. First, the dynamics of plasma within a tangled field is considered. We find that the contorted shape of the flux tubes significantly reduces the flow velocity compared to the supersonic free fall that would occur in a straight vertical tube. Second, linear force-free models of tangled fields are developed, and the elastic response of such fields to gravitational forces is considered. We demonstrate that the prominence plasma can be supported by the magnetic pressure of a tangled field that pervades not only the observed dense threads but also their local surroundings. Tangled fields with field strengths of about 10 G are able to support prominence threads with observed hydrogen density of the order of 10 11 cm -3 . Finally, we suggest that the observed vertical threads are the result of Rayleigh-Taylor instability. Simulations of the density distribution within a prominence thread indicate that the peak density is much larger than the average density. We conclude that tangled fields provide a viable mechanism for magnetic support of hedgerow prominences.

SisterTalk: final results of a culturally tailored cable television delivered weight control program for Black women.

Obesity among Black women continues to exceed that of other women. Most weight loss programs created without reference to specific cultural contexts are less effective for Black than White women. Weight control approaches accessible to Black women and adapted to relevant cultural contexts are important for addressing this problem. This paper reports the final results of SisterTalk, the randomized controlled trial of a cable TV weight control program oriented toward Black women. A five group design included a comparison group and a 2 × 2 factorial comparison of a) interactive vs. passive programming and b) telephone social support vs no telephone support, with 12 weekly initial cable TV programs followed by 4 monthly booster videos. At baseline, 3, 8, and 12 months post randomization, telephone and in person surveys were administered on diet, physical activity, and physical measurements of height and weight were taken to calculate body mass index (BMI). Analysis of variance (ANOVA) was used to examine differences over time, and between treatment and comparison groups. Dose variables reflecting use of the TV/video and written materials were also assessed. At 3 months, BMI, weight, and dietary fat were significantly lower and physical activity significantly higher among women exposed to the Cable TV intervention compared to the wait-list comparison group. Significant dietary fat differences were still observed at 8 and 12 month evaluations, but not BMI or physical activity differences. Main effects were not observed for interactive programming or enhanced social support at any time point. Within the intervention group, higher watching of the TV series and higher reading of educational materials were both (separately) associated with significantly lower dietary fat. Cable TV was an effective delivery channel to assist Black women with weight control, increasing physical activity and decreasing dietary fat during an initial intervention period, but only dietary

Fat talk is a form of self-degrading, thin-ideal endorsing communication that occurs within female friendship groups. Previous studies have suggested negative associations with wellbeing, but have been predominantly correlational and based on self-report. This study aimed to assess the causal relationship between fat talk and the correlates of disordered eating (thin-ideal internalization, body dissatisfaction, negative affect, and dieting intentions) by experimentally manipulating fat talk in existing friendship groups and measuring naturalistic expression of fat talk and its effects. Participants were 85 women aged 17-25 who completed the experiment in friendship pairs. They were randomly assigned to a condition in which their friend expressed fat talk, positive body talk, or neutral talk. This study found evidence of a causal link between listening to friends fat talk and increased correlates of disordered eating. The negative effects of listening to fat talk were fully mediated by fat talk expression. This study also revealed a social function of fat talk, whereby participants rated their friends more positively when they were perceived to behave consistently with group norms, either pro- or anti-fat talk. Positive body talk showed none of the negative effects of fat talk, and was considered socially acceptable regardless of existing friendship group norms. These findings indicate that fat talk is a mechanism through which the thin ideal is transmitted between individuals. Interventions at the level of the friendship group to challenge norms and communication styles may break the link between societal risk factors and individual risk of eating disorders. © 2015 Wiley Periodicals, Inc.

Magnetohydrodynamic (MHD) simulation of solar prominence formation

International Nuclear Information System (INIS)

Bao, J.

1987-01-01

Formation of Kippenhahn-Schluter type solar prominences by chromospheric mass injection is studied via numerical simulation. The numerical model is based on a two-dimensional, time-dependent magnetohydrodynamic (MHD) theory. In addition, an analysis of gravitational thermal MHD instabilities related to condensation is performed by using the small-perturbation method. The conclusions are: (1) Both quiescent and active-region prominences can be formed by chromospheric mass injection, provided certain optimum conditions are satisfied. (2) Quiescent prominences cannot be formed without condensation, though enough mass is supplied from chromosphere. The mass of a quiescent prominence is composed of both the mass injected from the chromosphere and the mass condensed from the corona. On the other hand, condensation is not important to active region prominence formation. (3) In addition to channeling and supporting effects, the magnetic field plays another important role, i.e. containing the prominence material. (4) In the model cases, prominences are supported by the Lorentz force, the gas-pressure gradient and the mass-injection momentum. (5) Due to gravity, more MHD condensation instability modes appear in addition to the basic condensation mode

This research examines young unmarried women's ways of talking about AIDS, AIDS prevention, and its relationship to mass media AIDS messages in Thailand. Data were derived from a survey conducted in four districts of Kanchanaburi province. Three hundred ninety-seven unmarried women were extracted from the approximately 1,800 original subjects for this analysis. Respondents were asked about the subjects and extent of their conversations about AIDS, the choice of discussion partners, considerations of social appropriateness in talking about the disease, as well as their risk perception. Important findings were that (a) women tend to talk about AIDS primarily with friends and siblings, (b) their reception level of mass media messages is related to the number of topics discussed and frequency of talks by the subjects, and (c) socioeconomic status and age are related to the variety and frequency of talking about AIDS. Implications for AIDS education are discussed.

Nonlinear MHD Waves in a Prominence Foot

Science.gov (United States)

Ofman, L.; Knizhnik, K.; Kucera, T.; Schmieder, B.

2015-11-01

We study nonlinear waves in a prominence foot using a 2.5D MHD model motivated by recent high-resolution observations with Hinode/Solar Optical Telescope in Ca ii emission of a prominence on 2012 October 10 showing highly dynamic small-scale motions in the prominence material. Observations of Hα intensities and of Doppler shifts show similar propagating fluctuations. However, the optically thick nature of the emission lines inhibits a unique quantitative interpretation in terms of density. Nevertheless, we find evidence of nonlinear wave activity in the prominence foot by examining the relative magnitude of the fluctuation intensity (δI/I ˜ δn/n). The waves are evident as significant density fluctuations that vary with height and apparently travel upward from the chromosphere into the prominence material with quasi-periodic fluctuations with a typical period in the range of 5-11 minutes and wavelengths <2000 km. Recent Doppler shift observations show the transverse displacement of the propagating waves. The magnetic field was measured with the THEMIS instrument and was found to be 5-14 G. For the typical prominence density the corresponding fast magnetosonic speed is ˜20 km s-1, in qualitative agreement with the propagation speed of the detected waves. The 2.5D MHD numerical model is constrained with the typical parameters of the prominence waves seen in observations. Our numerical results reproduce the nonlinear fast magnetosonic waves and provide strong support for the presence of these waves in the prominence foot. We also explore gravitational MHD oscillations of the heavy prominence foot material supported by dipped magnetic field structure.

We study nonlinear waves in a prominence foot using a 2.5D MHD model motivated by recent high-resolution observations with Hinode/Solar Optical Telescope in Ca ii emission of a prominence on 2012 October 10 showing highly dynamic small-scale motions in the prominence material. Observations of Hα intensities and of Doppler shifts show similar propagating fluctuations. However, the optically thick nature of the emission lines inhibits a unique quantitative interpretation in terms of density. Nevertheless, we find evidence of nonlinear wave activity in the prominence foot by examining the relative magnitude of the fluctuation intensity (δI/I ∼ δn/n). The waves are evident as significant density fluctuations that vary with height and apparently travel upward from the chromosphere into the prominence material with quasi-periodic fluctuations with a typical period in the range of 5–11 minutes and wavelengths <2000 km. Recent Doppler shift observations show the transverse displacement of the propagating waves. The magnetic field was measured with the THEMIS instrument and was found to be 5–14 G. For the typical prominence density the corresponding fast magnetosonic speed is ∼20 km s{sup −1}, in qualitative agreement with the propagation speed of the detected waves. The 2.5D MHD numerical model is constrained with the typical parameters of the prominence waves seen in observations. Our numerical results reproduce the nonlinear fast magnetosonic waves and provide strong support for the presence of these waves in the prominence foot. We also explore gravitational MHD oscillations of the heavy prominence foot material supported by dipped magnetic field structure.

Full Text Available Background Premenstrual syndrome (PMS is characterized by recurrent, moderate-to-severe affective, physical, and behavioral symptoms that develop during the luteal menstrual cycle and disappear within a few days of menstruation. Objectives This article aims to identify the effects of relaxation, positive self-talk, and a combination of relaxation and positive self-talk on premenstrual syndrome. Methods In this quasi-experimental study, 80 women with PMS disorder were selected using a simple random sampling method, in Hamadan, west of Iran. They were randomly divided into four groups. The first and second groups underwent positive self-talk and relaxation, respectively. The third group experienced positive self-talk and relaxation at the same time. The fourth group did not receive any treatment. The duration of treatment was 8 one-hour sessions. Data were collected using a PMS symptom severity questionnaire. All groups were followed up for six months after the intervention. Finally, data analysis was performed using SPSS version 18 for ANCOVA and Bonferroni tests. Results The results showed that compared to the control group, relaxation (23.2 and positive self-talk (21.25 treatment methods alone can reduce PMS (P < 0.001. On the other hand, a combined (relaxation + positive self-talk treatment method (13.75 was more effective in reducing PMS compared to relaxation or positive self-talk alone. Conclusions It seems that psychological therapy based on relaxation and positive self-talk can be significantly effective in reducing PMS.

Two Categories of Apparent Tornado-like Prominences

Martin, Sara F.; Venkataramanasastry, Aparna

2014-06-01

Two categories of solar prominences have been described in the literature as having a pattern of mass motions and/or a shape similar to terrestrial tornados. We first identify the two categories associated with prominences in the historic literature and then show that counterparts do exist for both in recent literature but one has not been called a tornado prominence. One category described as being similar to tornados is associated with the barbs of quiescent filaments but barbs appear to have rotational motion only under special conditions. H alpha Doppler observations from Helio Research confirm that this category is an illusion in our mind’s eye resulting from counterstreaming in the large barbs of quiescent filaments. The second category is a special case of rotational motion occurring during the early stages of some erupting prominences, in recent years called the roll effect in erupting prominences. In these cases, the eruption begins with the sideways rolling of the top of a prominence. As the eruption proceeds the rolling motion propagates down one leg or both legs of an erupting prominence depending on whether the eruption is asymmetric or symmetric respectively. As an asymmetric eruption proceeds, the longer lasting leg becomes nearly vertical and has true rotational motion. If only this phase of the eruption was observed, as in the historic cases, it was called a tornado prominence and spectra recorded in these cases provide proof of the rotational motion. When one observes an entire eruption which exhibits the rolling motion, as accomplished at Helio Research, the similarity to a tornado is lost because the event as a whole has quite a different nature and the analogy to a terrestrial tornado not longer appears suitable or helpful in understanding the observed and deduced physical processes. Our conclusion is that there are no solar prominences with motions that are usefully described as tornado or tornado-like events aside from the fun of observing

To identify individual therapist behaviors which elicit client change talk or sustain talk in motivational interviewing sessions. Motivational interviewing sessions from a single-session alcohol intervention delivered to college students were audio-taped, transcribed, and coded using the Motivational Interviewing Skill Code (MISC), a therapy process coding system. Participants included 92 college students and eight therapists who provided their treatment. The MISC was used to code 17 therapist behaviors related to the use of motivational interviewing, and client language reflecting movement toward behavior change (change talk), away from behavior change (sustain talk), or unrelated to the target behavior (follow/neutral). Client change talk was significantly more likely to immediately follow individual therapist behaviors [affirm (p=.013), open question (pmotivational interviewing can either elicit both client change talk and sustain talk or suppress both types of client language. Affirm was the only therapist behavior that both increased change talk and also reduced sustain talk. Copyright © 2015 Elsevier Inc. All rights reserved.

The award of the George E. Pake Prize honors not just me, but the many men and women who have devoted themselves to ``helping our nation secure a peaceful and free world through technology." These words comprise the core purpose of Sandia National Laboratories, and are also an apt description of Los Alamos, where I spent my early career, and of the US delegation to the Nuclear Testing Talks, where I served as the Ambassador and Chief Negotiator. In this talk, I will reflect on the opportunities to benefit the nation's and mankind's future through service in such endeavors.

Signs of helicity in solar prominences and related features

Science.gov (United States)

Martin, S.

This review illustrates several ways to identify the chirality (handedness) of solar prominences (filaments) from their structure and the structure of their surrounding magnetic fields in the chromosphere and corona. For prominences, these structural elements include the axial magnetic field direction, orientation of barbs, and direction of the prominence fine structure. The surrounding structures include the pattern of fibrils beneath the prominences and the pattern of coronal loops above the prominences. These ways of identifying chirality are then interpreted in terms of the formal definitions of helicity to yield a consistent set of one-to-one helicity relationships for all features. The helicity of some prominences can also be independently determined during their eruption by their fine structure, apparent crossings in the line-of-sight of different parts of the same prominence, and by large- scale twist of the prominence structure. Unlike observations of prominences (filaments) observed prior to eruption, in some cases evidence of both signs of helicity are found within the same erupting prominence. This indicates the continued application of forces on the prominences during the eruption process or the possible introduction of force(s) not present during earlier stages of their evolution.

Full Text Available Objectives were to gather information from Talking Circles of Aboriginal women who participated in a maternal Nutrition and Exercise Lifestyle Intervention Program (NELIP to identify strategies to bring NELIP into the community. Twelve First Nations women participated. Several main themes were identified regarding health: balance, knowledge/education and time management. Benefits of the NELIP were improvement in health, stamina, stress, and a healthy baby, no gestational diabetes and a successful home birth, with social support as an important contributing factor for success. Suggestions for improvement for the NELIP included group walking, and incorporating more traditional foods into the meal plan. The information gathered is the first step in determining strategies using participatory research and capacity-building to develop a community-based NELIP for pregnant Aboriginal women.

Challenging social myths and stereotypes of women and aging: heterosexual women talk about sex.

Science.gov (United States)

Hinchliff, Sharron; Gott, Merryn

2008-01-01

Cultural representations of aging and sexuality combine to paint a particular picture of mid and later life for women: menopause is constructed as a time when women either lose or renew their interest in sex, and later life a time when sexual activity no longer assumes importance yet remains vital to healthy aging. This article examines the importance of sexual activity to "older" women, paying particular attention to how they negotiate such representations. In-depth interviews were conducted with 19 women aged 50 and older recruited from Sheffield, UK. A material-discursive analysis revealed that whilst participants rejected the asexual discourse of aging they accepted it for women older than themselves. They constructed women per se as sexually complex, in comparison to men, making sexual activity "risky business" for women, and positioned their own sexual desire as responsive, either to a man's sexual desire or to their own hormones. Finally, sexual activity was constructed as having psychological and physiological benefits for couples within committed relationships. The findings are discussed in terms of their implications for research, theory and clinical practice.

Talking points for 8. meeting of Points of Contact for Recruitment of Women, 11 March 2010, Vienna, Austria

Full text: Ladies and Gentlemen, Dear Colleagues, This is my first opportunity as Director General to share with you my views on the representation of women in the Secretariat. For many years, the proportion of Professional women at the Agency was among the lowest in the UN system - about 18%. This partially reflected the traditionally low number of women in the nuclear sciences. We can take some pride in the progress that we have made in recent years. Women now account for around 23% of Professional staff. But this is still too low. The progress seen to date is a result of joint efforts by you, the Member States, and the Secretariat. The creation of this group - the Member States Points of Contact - has been key. Sixty Member States have designated Points of Contact. This means, however, that a surprisingly large number of countries, including some Board members, have not yet joined. I encourage them to sign up today. As Director General, I would like to see more women in senior positions and I want Agency staff to be recruited from as broad a geographical distribution as possible. In my first few months in office, I have already made special efforts to recruit women to Professional positions, with some success. My first concern is naturally to recruit the best qualified person. However, in selection processes I will always give prominent consideration to the need to proactively increase the number of women working in the Secretariat. More and more women are now working in the nuclear industry as engineers, managers, inspectors, chemists, physicists and environmentalists. But I must tell you honestly: while it is difficult to find well-qualified women for P-positions in the Agency, it is particularly difficult to find suitable female candidates for more senior posts. We very much need your help in getting the message out to highly-qualified women with long experience of the nuclear sector that the Agency is a great place to work. Change will not happen overnight

Nucleolar changes in cancer cells are one of the cytologic features important to the tumor pathologist in cancer assessments of tissue biopsies. However, inter-observer variability and the manual approach to this work hamper the accuracy of the assessment by pathologists. In this paper, we propose a computational method for prominent nucleoli pattern detection. Thirty-five hematoxylin and eosin stained images were acquired from prostate cancer, breast cancer, renal clear cell cancer and renal papillary cell cancer tissues. Prostate cancer images were used for the development of a computer-based automated prominent nucleoli pattern detector built on a cascade farm. An ensemble of approximately 1000 cascades was constructed by permuting different combinations of classifiers such as support vector machines, eXclusive component analysis, boosting, and logistic regression. The output of cascades was then combined using the RankBoost algorithm. The output of our prominent nucleoli pattern detector is a ranked set of detected image patches of patterns of prominent nucleoli. The mean number of detected prominent nucleoli patterns in the top 100 ranked detected objects was 58 in the prostate cancer dataset, 68 in the breast cancer dataset, 86 in the renal clear cell cancer dataset, and 76 in the renal papillary cell cancer dataset. The proposed cascade farm performs twice as good as the use of a single cascade proposed in the seminal paper by Viola and Jones. For comparison, a naive algorithm that randomly chooses a pixel as a nucleoli pattern would detect five correct patterns in the first 100 ranked objects. Detection of sparse nucleoli patterns in a large background of highly variable tissue patterns is a difficult challenge our method has overcome. This study developed an accurate prominent nucleoli pattern detector with the potential to be used in the clinical settings.

Disordered eating behavior-dieting, laxative use, fasting, binge eating-is common in college-aged women (11%-20%). A documented increase in the number of young women experiencing eating psychopathology has been blamed on the rise of engagement with social media sites such as Facebook. We predicted that college-aged women's Facebook intensity (e.g., the amount of time spent on Facebook, number of Facebook friends, and integration of Facebook into daily life), online physical appearance comparison (i.e., comparing one's appearance to others' on social media), and online "fat talk" (i.e., talking negatively about one's body) would be positively associated with their disordered eating behavior. In an online survey, 128 college-aged women (81.3% Caucasian, 6.7% Asian, 9.0% African-American, and 3.0% Other) completed items, which measured their disordered eating, Facebook intensity, online physical appearance comparison, online fat talk, body mass index, depression, anxiety, perfectionism, impulsivity, and self-efficacy. In regression analyses, Facebook intensity, online physical appearance comparison, and online fat talk were significantly and uniquely associated with disordered eating and explained a large percentage of the variance in disordered eating (60%) in conjunction with covariates. However, greater Facebook intensity was associated with decreased disordered eating behavior, whereas both online physical appearance comparison and online fat talk were associated with greater disordered eating. College-aged women who endorsed greater Facebook intensity were less likely to struggle with disordered eating when online physical appearance comparison was accounted for statistically. Facebook intensity may carry both risks and benefits for disordered eating. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Methods work better when couples talk.

Science.gov (United States)

Keller, S

1996-01-01

Sexual partners who communicate about reproductive health issues reduce their risk of acquiring a sexually transmitted disease (STD) or of unintended pregnancy, but few couples feel comfortable talking openly about sex. AIDS prevention programs have focused on improving couple communication, but family planning programs have emphasized women-controlled contraception as more reliable than barrier methods. The effectiveness of barrier methods would likely improve, however, if clients are counseled in couple communication. Effective communication about sexual issues requires self-confidence, and strengthening a woman's self-confidence may also improve her ability to negotiate condom use. Small discussion groups held among female factory workers in Thailand in 1993-94 led to an increase from 60% to 90% in the number of women who felt confident in discussing STD risk with a partner and to an increase from 36% to 82% in those who said they would not be embarrassed to give a partner a condom. A Nigerian study also suggested that more education may also improve prospects for couple communication and contraceptive usage. A US study showed that adolescent women who communicated openly with their partners reduced their risks of unintended pregnancy and STDs, and a Kenyan study indicated that communication increases contraceptive usage among married couples. Various projects around the world are attempting to counsel women on communication and condom negotiation, and counselors are beginning the difficult task of teaching women how to convince men to use condoms.

Topic prominence in Chinese EFL learners’ interlanguage

Directory of Open Access Journals (Sweden)

Shaopeng Li

2014-01-01

Full Text Available The present study aims to investigate the general characteristics of topicprominent typological interlanguage development of Chinese learners of English in terms of acquiring subject-prominent English structures from a discourse perspective. Topic structures mainly appear in Chinese discourse in the form of topic chains (Wang, 2002; 2004. The research target are the topic chain, which is the main topic-prominent structure in Chinese discourse, and zero anaphora, which is the most common topic anaphora in the topic chain. Two important findings emerged from the present study. First, the characteristics of Chinese topic chains are transferrable to the interlanguage of Chinese EFL learners, thus resulting in overgeneralization of the zero anaphora. Second, the interlanguage discourse of Chinese EFL learners reflects a change of the second language acquisition process from topic-prominence to subject-prominence, thus lending support to the discourse transfer hypothesis.

EUV observations of quiescent prominences from Skylab

International Nuclear Information System (INIS)

Moe, O.K.

1979-01-01

The authors report measurements of line intensities and line widths for three quiescent prominences observed with the Naval Research Laboratory slit spectrograph on ATM/Skylab. The wavelengths of the observed lines cover the range 1175 A to 1960 A. The measured intensities have been calibrated to within approximately a factor 2 and are average intensities over a 2 arc sec by 60 arc set slit. Nonthermal velocities are derived from the measured line widths. The nonthermal velocity is found to increase with temperature in the prominence transition zone. Electron densities and pressures are derived from density sensitive line ratios. Electron pressures for two of the prominences are found to lie in the range 0.04-0.08 dyn cm -2 , while values for the third and most intense and active of the three prominences are in the range 0.07-0.22 dyn cm -2 .

Multispacecraft observations of a prominence eruption

Directory of Open Access Journals (Sweden)

A. Bemporad

Full Text Available On 9 May 2007 a prominence eruption occurred at the West limb. Remarkably, the event was observed by the STEREO/EUVI telescopes and by the HINODE/EIS and SOHO/UVCS spectrometers. We present results from all these instruments. High-cadence (~37 s data from STEREO/EUVI A and B in the He II λ304 line were used to study the 3-D shape and expansion of the prominence. The high spatial resolution EUVI images (~1.5"/pixel have been used to infer via triangulation the 3-D shape and orientation of the prominence 12 min after the eruption onset. At this time the prominence has mainly the shape of a "hook" highly inclined southward, has an average thickness of 0.068 R⊙, a length of 0.43 R⊙ and lies, in first approximation, on a plane. Hence, the prominence is mainly a 2-D structure and there is no evidence for a twisted flux rope configuration. HINODE/EIS was scanning with the 2" slit the region where the filament erupted. The EIS spectra show during the eruption remarkable non-thermal broadening (up to ~100 km s−1 in the region crossed by the filament in spectral lines emitted at different temperatures, possibly with differences among lines from higher Fe ionization stages. The CME was also observed by the SOHO/UVCS instrument: the spectrograph slit was centered at 1.7 R⊙, at a latitude of 5° SW and recorded a sudden increase in the O VI λλ1032–1037 and Si XII λ520 spectral line intensities, representative of the CME front transit.

More than 2200 scientists coming from 37 countries participate in the ATLAS experiment. Only 17% of these are women. Why is this so? In Turkey, like elsewhere in the Balkans, there is a higher proportion of women physicists than in other European and North American countries. I will address this difference as well as examine the role of women in the ATLAS collaboration. I will also talk about the activities of the ATLAS Women's Network, of which Prof. Engin Arik was a founding member. Since Prof. Arik also worked hard to bring talented young Turkish students to CERN, I will also talk about the Engin Arik Fellowship which was created in memory of Engin and her colleagues, to continue her work offering research opportunities to young Turkish physicists.

Static current-sheet models of quiescent prominences

Science.gov (United States)

Wu, F.; Low, B. C.

1986-12-01

A particular class of theoretical models idealize the prominence to be a discrete flat electric-current sheet suspended vertically in a potential magnetic field. The weight of the prominence is supported by the Lorentz force in the current sheet. These models can be extended to have curved electric-current sheets and to vary three-dimensionally. The equation for force balance is 1 over 4 pi (del times B) times Bdel p- p9 z=zero. Using Cartesian coordinates we take, for simplicity, a uniform gravity with constant acceleration g in the direction -z. If we are interested not in the detailed internal structure of the prominence, but in the global magnetic configuration around the prominence, we may take prominence plasma to be cold. Consideration is given to how such equilibrium states can be constructed. To simplify the mathematical problem, suppose there is no electric current in the atmosphere except for the discrete currents in the cold prominence sheet. Let us take the plane z =0 to be the base of the atmosphere and restrict our attention to the domain z greater than 0. The task we have is to solve for a magnetic field which is everywhere potential except on some free surface S, subject to suit able to boundary conditions. The surface S is determined by requiring that it possesses a discrete electric current density such that the Lorentz force on it is everywhere vertically upward to balance the weight of the material m(S). Since the magnetic field is potential in the external atmosphere, the latter is decoupled from the magnetic field and its plane parallel hydrostatic pressure and density can be prescribed.

Black women talk about workplace stress and how they cope.

2012-01-01

Black women face the same struggles as White women; however, they have to face issues of diversity on top of inequality. The purpose of this study was to explore work-related stressors that affect the lives of Black women and how they cope with them. Using an exploratory design with grounded-theory methods, five basic themes emerged that identify when racism and sexism are experienced as stressors for African American women in the workplace. The themes are: (1) being hired or promoted in the workplace, (2) defending one’s race and lack of mentorship, (3) shifting or code switching to overcome barriers to employment, (4) coping with racism and discrimination, and (5) being isolated and/or excluded. The results from this study indicate African American women use emotion- and problem-focused coping responses to manage stress (e.g., racism and sexism) in the workplace. The article concludes with a discussion of practice implications of these findings.

Neutral Atom Diffusion in a Partially Ionized Prominence Plasma

Science.gov (United States)

Gilbert, Holly

2010-01-01

The support of solar prominences is normally described in terms of a magnetic force on the prominence plasma that balances the solar gravitational force. Because the prominence plasma is only partially ionized. it is necessary to consider in addition the support of the neutral component of the prominence plasma. This support is accomplished through a frictional interaction between the neutral and ionized components of the plasma, and its efficacy depends strongly on the degree of ionization of the plasma. More specifically, the frictional force is proportional to the relative flow of neutral and ion species, and for a sufficiently weakly ionized plasma, this flow must be relatively large to produce a frictional force that balances gravity. A large relative flow, of course, implies significant draining of neutral particles from the prominence. We evaluate the importance of this draining effect for a hydrogen-helium plasma, and consider the observational evidence for cross-field diffusion of neutral prominence material,

Our purpose in conducting this qualitative study was to examine how a multiethnic sample of women living in Hilo, Hawai'i, describe menopause. Interviews were conducted with 185 pre-, peri-, and post-menopausal women aged 45 to 55. We found that pre-menopausal women felt anxious compared with peri- and post-menopausal women's more affirmative attitudes of increasing confidence and freedom in this new cycle of life. A dominant theme was the construction of a post-menstrual identity. Peri-and post-menopausal women's attitudes were not biomedically oriented. Local culture and the island lifestyle may provide a positive atmosphere for women going through menopause.

The objectification of women in mainstream pornographic videos in Australia.

2005-11-01

Using twelve measures of objectification, I measured the degree to which women are objectified in mainstream pornographic videos in Australia. Seven of the measures allowed for direct comparison of female and male objectification. Of these, one shows women being more objectified than men (presence of orgasms, where women have fewer orgasms). Three show men being more objectified than women (in time spent looking at camera, where men return the gaze significantly less; in time spent talking to the camera, where they are also less engaged; and in initiating sex, where men are more sexual objects than active sexual subjects in seeking their sexual pleasure in the sample). Three measures showed no difference in objectification between men and women (naming, central characters, and time spent talking to other characters).

Most women in Canada confront a combination of bio-psychosocial factors that put them at risk for cardiovascular disease. The challenge for health planners is to address these factors while contextualizing interventions that meet the specific needs of particular social and cultural groupings. The article will discuss a women-centered, group-based heart health pilot initiative designed to engage with indigenous approaches to healing. The nurse practitioners co-led the group with a representative from the indigenous community to balance women-centered practices with more traditional and culturally appropriate ones. In particular, indigenous processes, such as a Talking Circle, combined with indigenous knowledge/content were integrated into the pilot program. The project was evaluated to investigate its outcomes (how the intervention impacted the participants) and processes (how participants perceived the intervention). Evaluation involved analysis of the Talking Circle's content, a focus group, field observations, and self-completed surveys. Most women made changes regarding their diet, some began physical activities, and others focused on better managing their emotional health. Women viewed the group as successful because it embraced both women-centered and culturally appropriate health promotion practices. The intervention created a culturally safe space for learning and transformation. The findings confirm the need for employing culturally relevant, gender-specific approaches to heart health promotion that are situated in and responsive to community needs. © 2016 Society for Public Health Education.

Coping with stress and by stress: Russian men and women talking about transition, stress and health.

Science.gov (United States)

Pietilä, Ilkka; Rytkönen, Marja

2008-01-01

Several studies have claimed stress to be a major reason for poor public health in Russia and referred to significant social changes as a reason for the high level of perceived stress among Russians. This article aims to examine how stress and its relation to health are interpreted in the context of everyday life in Russian men's and women's interview talk with a focus on descriptions of recent social changes. The research material consists of 29 thematic interviews of men and women from St. Petersburg aged 15-81. In the analysis of contextual constructions of stress, we found that stress was used not only within a context of an individual's own life as an expression of a strained psycho-physiological state but also denoted larger societal processes and changes. In addition to individual experiences, the whole of Russian society was described as suffering from stress. Throughout the material, most interviewees, whilst outspokenly blaming stress for deteriorating physical health, met difficulties in making concrete these negative influences. Based on analysis, we interpret our interviewees' accounts of stress as a part of the cultural discourse wherein 'stress' serves as a conceptual tool in making interpretations about both the people and their social environment. Stress, as a concept, has emerged in a wide range of different institutional sites, such as the media and public health policy and has become a discursive entity of contemporary social life in Russia. We claim that it has simultaneously become an intermediary concept articulating a shared, cultural experience of the changes in Russian society and their effects on individuals' everyday life and health. Thus, the concept of stress helps people to articulate, make sensible, and cope with the impacts of transition on their individual lives.

TORNADO-LIKE EVOLUTION OF A KINK-UNSTABLE SOLAR PROMINENCE

We report on the tornado-like evolution of a quiescent prominence on 2014 November 1. The eastern section of the prominence first rose slowly, transforming into an arch-shaped structure as high as ∼150 Mm above the limb; the arch then writhed moderately in a left-handed sense, while the original dark prominence material emitted in the Fe ix 171 Å passband, and a braided structure appeared at the eastern edge of the warped arch. The unraveling of the braided structure was associated with a transient brightening in the EUV and apparently contributed to the formation of a curtain-like structure (CLS). The CLS consisted of myriad thread-like loops rotating counterclockwise about the vertical if viewed from above. Heated prominence material was observed to slide along these loops and land outside the filament channel. The tornado eventually disintegrated and the remaining material flew along a left-handed helical path constituting approximately a full turn, as corroborated through stereoscopic reconstruction, into the cavity of the stable, western section of the prominence. We suggest that the tornado-like evolution of the prominence was governed by the helical kink instability, and that the CLS formed through magnetic reconnections between the prominence field and the overlying coronal field.

Solar Tornado Prominences: Plasma Motions Along Filament Barbs

Science.gov (United States)

Panasenco, Olga; Velli, Marco; Martin, Sara F.; Rappazzo, Franco

2013-03-01

Recent high-resolution observations from the Solar Dynamic Observatory (SDO) have reawakened interest in the old and fascinating phenomenon of solar tornado prominences. This class of prominences was first introduced by E. Pettit in 1932, who studied them over many years up to 1950. High resolution and high cadence multi-wavelength data obtained by SDO reveal that the tornado-like properties of these prominences are mainly an illusion due to projection effects. We show that counterstreaming plasma motions with projected velocities up to +/- 45 km/sec along the prominence spine and barbs create a tornado-like impression when viewed at the limb. We demonstrate that barbs are often rooted at the intersection between 4-5 supergranular cells. We discuss the observed oscillations along the vertical parts of barbs and whether they may be related to vortex flows coming from the convection downdrafts at the intersection of supergranules (and possibly smaller convective cells) in the photosphere and their entrained magnetic field. The unwinding of magnetic threads near the photosphere via reconnection might be a source of the waves which are observed as oscillations in prominence barbs.

Spectropolarimetric observations of prominences have been obtained with the THEMIS telescope during four years of coordinated campaigns. Our aim is now to understand the conditions of the cool plasma and magnetism in “atypical” prominences, namely when the measured inclination of the magnetic field departs, to some extent, from the predominantly horizontal field found in “typical” prominences. What is the role of the magnetic field in these prominence types? Are plasma dynamics more important in these cases than the magnetic support? We focus our study on three types of “atypical” prominences (tornadoes, bubbles, and jet-like prominence eruptions) that have all been observed by THEMIS in the He i D{sub 3} line, from which the Stokes parameters can be derived. The magnetic field strength, inclination, and azimuth in each pixel are obtained by using the inversion method of principal component analysis on a model of single scattering in the presence of the Hanle effect. The magnetic field in tornadoes is found to be more or less horizontal, whereas for the eruptive prominence it is mostly vertical. We estimate a tendency toward higher values of magnetic field strength inside the bubbles than outside in the surrounding prominence. In all of the models in our database, only one magnetic field orientation is considered for each pixel. While sufficient for most of the main prominence body, this assumption appears to be oversimplified in atypical prominence structures. We should consider these observations as the result of superposition of multiple magnetic fields, possibly even with a turbulent field component.

The Computational Processing of Intonational Prominence: A Functional Prosody Perspective

OpenAIRE

Nakatani, Christine Hisayo

1997-01-01

Intonational prominence, or accent, is a fundamental prosodic feature that is said to contribute to discourse meaning. This thesis outlines a new, computational theory of the discourse interpretation of prominence, from a FUNCTIONAL PROSODY perspective. Functional prosody makes the following two important assumptions: first, there is an aspect of prominence interpretation that centrally concerns discourse processes, namely the discourse focusing nature of prominence; and second, the role of p...

An International Perspective on Women in Physics

Michelman-Ribeiro, Ariel

2006-03-01

The 1^st International Union of Pure and Applied Physics (IUPAP) Conference on Women in Physics, held in 2002 in Paris, France, highlighted a number of issues facing women physicists around the world. A second conference was held in May 2005 in Rio de Janeiro, Brazil, with the goal of examining the progress made since the last conference and also to provide an opportunity for the delegates to present their research, both physics research and gender-related research, and to make contacts for future collaborations. The conference was attended by 145 delegates from 42 countries, including a very diverse delegation of 22 women and men from the U.S. The conference was organized by the Working Group on Women in Physics of IUPAP, which is charged with making recommendations to IUPAP on how to attract, retain, and increase the participation of women in physics at all levels. The conference included a round table discussion on ``Research Funding and Women in Physics,'' several plenary talks, a poster session on women in physics in each country, a poster session on research by individual delegates, and discussion groups on six topics including attracting girls into physics, launching a successful career, getting women into leadership, improving the institutional climate, learning from regional differences, and balancing family and career. Conference proceedings have been published that include research abstracts, summaries from the discussion groups, articles on the plenary talks, and papers from each country on the status of women in physics in their country (proceedings can be found at http://proceedings.aip.org/proceedings/confproceed/795.jsp). This talk will discuss the U. S. delegation and their country paper on the situation for women in physics in the U.S. as well as highlights from the information presented by the delegates from other nations. The outcomes of the 2002 conference will be described briefly and then the signs of progress noted in 2005 will be summarized.

2017-01-01

Conversational robots and agents are being designed for educational and/or persuasive tasks, e.g., health or fitness coaching. To pursue such tasks over a long time, they will need a complex model of the strategic goal, a variety of strategies to implement it in interaction, and the capability of strategic talk. Strategic talk is incipient ongoing conversation in which at least one participant has the objective of changing the other participant's attitudes or goals. The paper is based on the observation that strategic talk can stretch over considerable periods of time and a number of conversational segments. Film dialogues are taken as a source to develop a model of the strategic talk of mentor characters. A corpus of film mentor utterances is annotated on the basis of the model, and the data are interpreted to arrive at insights into mentor behavior, especially into the realization and sequencing of strategies.

Magnetic Field-Vector Measurements in Quiescent Prominences via the Hanle Effect: Analysis of Prominences Observed at Pic-Du-Midi and at Sacramento Peak

Science.gov (United States)

Bommier, V.; Leroy, J. L.; Sahal-Brechot, S.

1985-01-01

The Hanle effect method for magnetic field vector diagnostics has now provided results on the magnetic field strength and direction in quiescent prominences, from linear polarization measurements in the He I E sub 3 line, performed at the Pic-du-Midi and at Sacramento Peak. However, there is an inescapable ambiguity in the field vector determination: each polarization measurement provides two field vector solutions symmetrical with respect to the line-of-sight. A statistical analysis capable of solving this ambiguity was applied to the large sample of prominences observed at the Pic-du-Midi (Leroy, et al., 1984); the same method of analysis applied to the prominences observed at Sacramento Peak (Athay, et al., 1983) provides results in agreement on the most probable magnetic structure of prominences; these results are detailed. The statistical results were confirmed on favorable individual cases: for 15 prominences observed at Pic-du-Midi, the two-field vectors are pointing on the same side of the prominence, and the alpha angles are large enough with respect to the measurements and interpretation inaccuracies, so that the field polarity is derived without any ambiguity.

PROMINENCE ACTIVATION BY CORONAL FAST MODE SHOCK

An X5.4 class flare occurred in active region NOAA11429 on 2012 March 7. The flare was associated with a very fast coronal mass ejection (CME) with a velocity of over 2500 km s{sup −1}. In the images taken with the Solar Terrestrial Relations Observatory-B/COR1, a dome-like disturbance was seen to detach from an expanding CME bubble and propagated further. A Type-II radio burst was also observed at the same time. On the other hand, in extreme ultraviolet images obtained by the Solar Dynamic Observatory/Atmospheric Imaging Assembly (AIA), the expanding dome-like structure and its footprint propagating to the north were observed. The footprint propagated with an average speed of about 670 km s{sup −1} and hit a prominence located at the north pole and activated it. During the activation, the prominence was strongly brightened. On the basis of some observational evidence, we concluded that the footprint in AIA images and the ones in COR1 images are the same, that is, the MHD fast mode shock front. With the help of a linear theory, the fast mode Mach number of the coronal shock is estimated to be between 1.11 and 1.29 using the initial velocity of the activated prominence. Also, the plasma compression ratio of the shock is enhanced to be between 1.18 and 2.11 in the prominence material, which we consider to be the reason for the strong brightening of the activated prominence. The applicability of linear theory to the shock problem is tested with a nonlinear MHD simulation.

Magnetohydrodynamic interpretation of the motion of prominences

International Nuclear Information System (INIS)

Sakurai, Takashi

1976-01-01

We study three types of prominence eruptions, which we will call the arch type, the loop type, and the gigantic arch type, respectively, from their shapes. If we regard the prominence as a magnetic flux tube, the onset of its ascending motion can be interpreted as the motion due to the screw-mode instability, which is the most unstable mode of instabilities of a magnetofluid column (pinch). The growth rate of this mode is evaluated and is shown to be consistent with the time scale of the initial stage of the eruption. In order to study the nonlinear stage of the instability, we propose a method of numerical calculation based on a variational technique known as Ritz's method. The result shows that the characteristic motion of the arch-, loop-, and gigantic arch-type eruptions may be reproduced by perturbing a model sequence with decreasing pitch angles of the unperturbed helical magnetic field lines. This conclusion seems to be supported by the pitch angles of observed threads in each type of prominence and also by the fact that the observed time profiles of the rising velocity of the prominences of each type agree well with those predicted from model calculations.

Solar Magnetized Tornadoes: Rotational Motion in a Tornado-like Prominence

Su, Yang; Gömöry, Peter; Veronig, Astrid; Temmer, Manuela; Wang, Tongjiang; Vanninathan, Kamalam; Gan, Weiqun; Li, YouPing

2014-04-01

Su et al. proposed a new explanation for filament formation and eruption, where filament barbs are rotating magnetic structures driven by underlying vortices on the surface. Such structures have been noticed as tornado-like prominences when they appear above the limb. They may play a key role as the source of plasma and twist in filaments. However, no observations have successfully distinguished rotational motion of the magnetic structures in tornado-like prominences from other motions such as oscillation and counter-streaming plasma flows. Here we report evidence of rotational motions in a tornado-like prominence. The spectroscopic observations in two coronal lines were obtained from a specifically designed Hinode/EIS observing program. The data revealed the existence of both cold and million-degree-hot plasma in the prominence leg, supporting the so-called prominence-corona transition region. The opposite velocities at the two sides of the prominence and their persistent time evolution, together with the periodic motions evident in SDO/AIA dark structures, indicate a rotational motion of both cold and hot plasma with a speed of ~5 km s-1.

Morphology and Dynamics of Solar Prominences from 3D MHD Simulations

Terradas, J.; Soler, R.; Luna, M.; Oliver, R.; Ballester, J. L.

2015-01-01

In this paper we present a numerical study of the time evolution of solar prominences embedded in sheared magnetic arcades. The prominence is represented by a density enhancement in a background-stratified atmosphere and is connected to the photosphere through the magnetic field. By solving the ideal magnetohydrodynamic equations in three dimensions, we study the dynamics for a range of parameters representative of real prominences. Depending on the parameters considered, we find prominences that are suspended above the photosphere, i.e., detached prominences, but also configurations resembling curtain or hedgerow prominences whose material continuously connects to the photosphere. The plasma-β is an important parameter that determines the shape of the structure. In many cases magnetic Rayleigh-Taylor instabilities and oscillatory phenomena develop. Fingers and plumes are generated, affecting the whole prominence body and producing vertical structures in an essentially horizontal magnetic field. However, magnetic shear is able to reduce or even to suppress this instability.

Assessing the Accuracy of Self-Reported Self-Talk

2015-05-01

Full Text Available Self-Talk Scale (STS; Brinthaupt, Hein, & Kramer, 2009 is a self-report measure of self-talk frequency that has been shown to possess acceptable reliability and validity. However, no research using the STS has examined the accuracy of respondents’ self-reports. In the present paper, we report a series of studies directly examining the measurement of self-talk frequency and functions using the STS. The studies examine ways to validate self-reported self-talk by (1 comparing STS responses from 6 weeks earlier to recent experiences that might precipitate self-talk, (2 using experience sampling methods to determine whether STS scores are related to recent reports of self-talk over a period of a week, and (3 comparing self-reported STS scores to those provided by a significant other who rated the target on the STS. Results showed that (1 overall self-talk scores, particularly self-critical and self-reinforcing self-talk, were significantly related to reports of context-specific self-talk; (2 high STS scorers reported talking to themselves significantly more often during recent events compared to low STS scorers, and, contrary to expectations, (3 friends reported less agreement than strangers in their self-other self-talk ratings. Implications of the results for the validity of the STS and for measuring self-talk are presented.

Reconnection–Condensation Model for Solar Prominence Formation

2017-08-10

We propose a reconnection–condensation model in which topological change in a coronal magnetic field via reconnection triggers radiative condensation, thereby resulting in prominence formation. Previous observational studies have suggested that reconnection at a polarity inversion line of a coronal arcade field creates a flux rope that can sustain a prominence; however, they did not explain the origin of cool dense plasmas of prominences. Using three-dimensional magnetohydrodynamic simulations, including anisotropic nonlinear thermal conduction and optically thin radiative cooling, we demonstrate that reconnection can lead not only to flux rope formation but also to radiative condensation under a certain condition. In our model, this condition is described by the Field length, which is defined as the scale length for thermal balance between radiative cooling and thermal conduction. This critical condition depends weakly on the artificial background heating. The extreme ultraviolet emissions synthesized with our simulation results have good agreement with observational signatures reported in previous studies.

These papers deal with recent theoretical and observational studies of the physics of solar prominences. Specific topics include reviews of prominence spectra and their interpretation, polarimetric observations and magnetic-field determination in prominences, observations of the prominence-corona interface, theories on the formation and stability of quiescent prominences, prominence classifications, observations of active prominences, observations and interpretations of coronal manifestations of eruptive prominences, and models of prominence structure and dynamics. Other contributions discuss simultaneous observations of Ca II and hydrogen Balmer lines in quiescent prominences, recent results in quiescent-prominence spectroscopy, the solar helium abundance obtained from optical spectra of quiescent prominences, and Stokes polarimetry of quiescent prominences in the He I D3 line. Magnetic-field determination based on the Hanle effect is also examined, along with the orientation of prominence microstructure relative to magnetic-field direction, radio observations of quiescent-prominence filaments at centimeter and millimeter wavelengths, EUV observations of filaments, and a magnetic-field reconnection model of quiescent prominences.

Su et al. proposed a new explanation for filament formation and eruption, where filament barbs are rotating magnetic structures driven by underlying vortices on the surface. Such structures have been noticed as tornado-like prominences when they appear above the limb. They may play a key role as the source of plasma and twist in filaments. However, no observations have successfully distinguished rotational motion of the magnetic structures in tornado-like prominences from other motions such as oscillation and counter-streaming plasma flows. Here we report evidence of rotational motions in a tornado-like prominence. The spectroscopic observations in two coronal lines were obtained from a specifically designed Hinode/EIS observing program. The data revealed the existence of both cold and million-degree-hot plasma in the prominence leg, supporting the so-called prominence-corona transition region. The opposite velocities at the two sides of the prominence and their persistent time evolution, together with the periodic motions evident in SDO/AIA dark structures, indicate a rotational motion of both cold and hot plasma with a speed of ∼5 km s{sup –1}.

Prominence-corona interface compared with the chromosphere-corona transition region

Energy Technology Data Exchange (ETDEWEB)

Orrall, F Q; Schmahl, E J [Harvard Coll. Observatory, Cambridge, Mass. (USA)

1976-11-01

The intensities of 52 EUV emission lines from each of 9 hedgerow prominences observed at the limb with the Harvard experiment on ATM-Skylab have been compared with intensities from the interior of network cells at the center of the disk, in order to compare the prominence-corona (P-C) interface with the chromosphere-corona (C-C) transition region. The intensity ratio Isub(cell)/Isub(prominence) for each line varies systematically (in all of the prominences observed), with the temperature of formation of the line as approximately Tsup(-0.6). The density sensitive C III (formed at T approximately 9x10/sup 4/ K) line ratio Isub(lambda1175)/Isub(lambda977) implies an average density 1.3x10/sup 9/ electrons cm/sup -3/ in the P-C interface and approximately 4 times this value in the C-C transition of the cells. The total optical thickness at the head of the Lyman continuum is < approximately 10 in most of the prominences studied; in two of the prominences, however, the possibility that tau/sub 0/ is large cannot be rejected. Methods of analysis of these EUV data are developed assuming both a resolved and an unresolved internal prominence structure. Although the systematic differences between the P-C interface and the C-C transition are stressed, the similarities are probably more remarkable and may be a result of fine structure in the C-C transition.

MULTI-LINE STOKES INVERSION FOR PROMINENCE MAGNETIC-FIELD DIAGNOSTICS

International Nuclear Information System (INIS)

Casini, R.; Lopez Ariste, A.; Paletou, F.; Leger, L.

2009-01-01

We present test results on the simultaneous inversion of the Stokes profiles of the He I lines at 587.6 nm (D 3 ) and 1083.0 nm in prominences (90 deg. scattering). We created data sets of synthetic Stokes profiles for the case of quiescent prominences (B -3 of the peak intensity for the polarimetric sensitivity of the simulated observations. In this work, we focus on the error analysis for the inference of the magnetic field vector, under the usual assumption that the prominence can be assimilated to a slab of finite optical thickness with uniform magnetic and thermodynamic properties. We find that the simultaneous inversion of the two lines significantly reduces the errors on the inference of the magnetic field vector, with respect to the case of single-line inversion. These results provide a solid justification for current and future instrumental efforts with multi-line capabilities for the observations of solar prominences and filaments.

This review paper outlines background information and covers recent advances made via the analysis of spectra and images of prominence plasma and the increased sophistication of non-LTE (i.e. when there is a departure from Local Thermodynamic Equilibrium) radiative transfer models. We first describe the spectral inversion techniques that have been used to infer the plasma parameters important for the general properties of the prominence plasma in both its cool core and the hotter prominence-corona transition region. We also review studies devoted to the observation of bulk motions of the prominence plasma and to the determination of prominence mass. However, a simple inversion of spectroscopic data usually fails when the lines become optically thick at certain wavelengths. Therefore, complex

Rodger, Andrew; Labrosse, Nicolas

2017-09-01

Our aim is to test potential solar prominence plasma diagnostics as obtained with the new solar capability of the Atacama Large Millimeter/submillimeter Array (ALMA). We investigate the thermal and plasma diagnostic potential of ALMA for solar prominences through the computation of brightness temperatures at ALMA wavelengths. The brightness temperature, for a chosen line of sight, is calculated using the densities of electrons, hydrogen, and helium obtained from a radiative transfer code under non-local thermodynamic equilibrium (non-LTE) conditions, as well as the input internal parameters of the prominence model in consideration. Two distinct sets of prominence models were used: isothermal-isobaric fine-structure threads, and large-scale structures with radially increasing temperature distributions representing the prominence-to-corona transition region. We compute brightness temperatures over the range of wavelengths in which ALMA is capable of observing (0.32 - 9.6 mm), however, we particularly focus on the bands available to solar observers in ALMA cycles 4 and 5, namely 2.6 - 3.6 mm (Band 3) and 1.1 - 1.4 mm (Band 6). We show how the computed brightness temperatures and optical thicknesses in our models vary with the plasma parameters (temperature and pressure) and the wavelength of observation. We then study how ALMA observables such as the ratio of brightness temperatures at two frequencies can be used to estimate the optical thickness and the emission measure for isothermal and non-isothermal prominences. From this study we conclude that for both sets of models, ALMA presents a strong thermal diagnostic capability, provided that the interpretation of observations is supported by the use of non-LTE simulation results.

Solar tornadoes are dark vertical filamentary structures observed in the extreme ultraviolet associated with prominence legs and filament barbs. Their true nature and relationship to prominences requires an understanding of their magnetic structure and dynamic properties. Recently, a controversy has arisen: is the magnetic field organized forming vertical, helical structures or is it dominantly horizontal? And concerning their dynamics, are tornadoes really rotating or is it just a visual illusion? Here we analyze four consecutive spectro-polarimetric scans of a prominence hosting tornadoes on its legs, which helps us shed some light on their magnetic and dynamical properties. We show that the magnetic field is very smooth in all the prominence, which is probably an intrinsic property of the coronal field. The prominence legs have vertical helical fields that show slow temporal variation that is probably related to the motion of the fibrils. Concerning the dynamics, we argue that (1) if rotation exists, it is intermittent, lasting no more than one hour, and (2) the observed velocity pattern is also consistent with an oscillatory velocity pattern (waves).

Fat Talk Free Week (FTFW), a social marketing campaign designed to decrease self-disparaging talk about body and weight, has not yet been evaluated. We conducted a theory-informed pilot evaluation of FTFW with two college samples using a pre- and posttest design. Aligned with the central tenets of the Elaboration Likelihood Model (ELM), we investigated the importance of FTFW saliency as a predictor of fat talk behavior change. Our analytic sample consisted of 118 female participants (83% of original sample). Approximately 76% of the sample was non-Hispanic White, 14% Asian, and 8% Hispanic. At baseline, more than 50% of respondents reported engaging in frequent self fat talk; at posttest, this number dropped to 34% of respondents. Multivariable regression models supported campaign saliency as the single strongest predictor of a decrease in self fat talk. Our results support the social diffusion of campaign messages among shared communities, as we found significant decreases in fat talk among campaign attenders and nonattenders. FTFW may be a promising short-term health communication campaign to reduce fat talk, as campaign messages are salient among university women and may encourage interpersonal communication.

Talk Shows in Pakistan TV Culture: Engaging Women as Cultural Citizens

Full Text Available Gendered content that travels through popular TV in Pakistan highlights gender-based crimes and allows women access to the mediated public sphere. This is an unprecedented form of access in a society that defines public/private through Shariah. The boundaries between the two spheres have thus far been immutable. Recent changes in the media landscape have made these boundaries porous. Drawing on theoretical debates on popular culture, cultural citizenship and counter public sphere, the study argues that these popular cultural spaces can be read in terms of an emerging feminist public sphere where women can engage as members of the public and as cultural citizens. To determine engagement patterns of young viewers, focus groups turned out to be effective method. In the sample of university students, there were 42 participants in 10 groups with 4 to 6 members in each group. The study finds that gendered content allows women to act in pro-civic ways. Their engagement with this content allows viewers to revisit their intersecting identities as Muslims, women and Pakistanis.

Aesthetic Refinements in Patients with Prominent Eyes.

The treatment of prominent eyes is still a challenging task. As well as the surgery, proper preoperative diagnosis differentiating between patients with and without Graves ophthalmopathy plays an important role. In functionally asymptomatic patients with Graves disease suffering from the aesthetic impairment of prominent eyes, the transpalpebral decompression by intraorbital fat removal technique has been proved to be reliable, effective, safe, and easily performed by a trained and experienced oculoplastic surgeon. This technique provides long-lasting results, leading to improvement not only in visual function but also in personal well-being and in the patient's social life, with a high benefit-to-risk ratio. The most powerful tool to treat the lower lid deformity and malar bags in patients without Graves disease is the subperiosteal midface lift. It shortens the lid-cheek junction and blends the retaining periorbital ligaments. Furthermore, it adds volume to the lower lid and gives a stable support. By the nature of the procedure, it also turns a negative into a positive vector. In experienced hands, Olivari's orbital decompression and Hester's midface lift are ideal options for the treatment of prominent eyes.

The launch of the Hinode satellite has allowed for seeing-free observations at high-resolution and high-cadence making it well suited to study the dynamics of quiescent prominences. In recent years it has become clear that quiescent prominences support small-amplitude transverse oscillations, however, sample sizes are usually too small for general conclusions to be drawn. We remedy this by providing a statistical study of transverse oscillations in vertical prominence threads. Over a 4 hr period of observations it was possible to measure the properties of 3436 waves, finding periods from 50 to 6000 s with typical velocity amplitudes ranging between 0.2 and 23 km s{sup –1}. The large number of observed waves allows the determination of the frequency dependence of the wave properties and derivation of the velocity power spectrum for the transverse waves. For frequencies less than 7 mHz, the frequency dependence of the velocity power is consistent with the velocity power spectra generated from observations of the horizontal motions of magnetic elements in the photosphere, suggesting that the prominence transverse waves are driven by photospheric motions. However, at higher frequencies the two distributions significantly diverge, with relatively more power found at higher frequencies in the prominence oscillations. These results highlight that waves over a large frequency range are ubiquitous in prominences, and that a significant amount of the wave energy is found at higher frequency.

Quiescent Prominences in the Era of ALMA. II. Kinetic Temperature Diagnostics

Gunár, Stanislav; Heinzel, Petr; Anzer, Ulrich; Mackay, Duncan H.

2018-01-01

We provide the theoretical background for diagnostics of the thermal properties of solar prominences observed by the Atacama Large Millimeter/submillimeter Array (ALMA). To do this, we employ the 3D Whole-Prominence Fine Structure (WPFS) model that produces synthetic ALMA-like observations of a complex simulated prominence. We use synthetic observations derived at two different submillimeter/millimeter (SMM) wavelengths—one at a wavelength at which the simulated prominence is completely optically thin and another at a wavelength at which a significant portion of the simulated prominence is optically thick—as if these were the actual ALMA observations. This allows us to develop a technique for an analysis of the prominence plasma thermal properties from such a pair of simultaneous high-resolution ALMA observations. The 3D WPFS model also provides detailed information about the distribution of the kinetic temperature and the optical thickness along any line of sight. We can thus assess whether the measure of the kinetic temperature derived from observations accurately represents the actual kinetic temperature properties of the observed plasma. We demonstrate here that in a given pixel the optical thickness at the wavelength at which the prominence plasma is optically thick needs to be above unity or even larger to achieve a sufficient accuracy of the derived information about the kinetic temperature of the analyzed plasma. Information about the optical thickness cannot be directly discerned from observations at the SMM wavelengths alone. However, we show that a criterion that can identify those pixels in which the derived kinetic temperature values correspond well to the actual thermal properties in which the observed prominence can be established.

Polytetrafluoroethylene (PTFE) is a typical fluoropolymer and it has several desirable technological properties such as electrical insulation, solid lubrication etc. However, the conventional microstructuring methods have not been well applied to PTFE due to its chemical inertness. Some effective micromachining using synchrotron radiation or ion beam irradiation has been reported. In this study, we create micro-prominences by raising the original surface using proton beam writing (PBW) without chemical etching. A conical prominence was formed by spiral drawing from the center with a 3 MeV proton beam. The body was porous, and the bulk PTFE below the prominence changed to fragmented structures. With decreasing writing speed, the prominence became taller but the height peaked. The prominence gradually reduced in size after the speed reached the optimum value. We expect that these porous projections with high aspect ratio will be versatile in medical fields and microelectromechanical systems (MEMS) technology.

Women at Work and Men at Home: A Transition for Sustainable Development

2017-08-01

Full Text Available The issue of women empowerment has picked up a great attention and pace in the recent years. Women stepped out of the homes and started working although they continue to juggle between paid work and unpaid work at workplace and home respectively. Even as workplaces for women have increasingly become promotive of their professional and personal development through provision of policies such as work from home, flexible shifts, maternity entitlements among others there is still time when inclusion of all women in the workforce and inclusion of all men in the “home-force” is achieved. Families have started placing value to women’s education and employment, instead of limiting them to only home-boundaries. However, it is essential to understand the ground reality. Are we in a position to say that employment is synonymous to empowerment? As women have stepped out of home in large numbers, have men stepped inside the home in an appreciable manner? This paper attempts to talk about such pressing issues, which even though not talked about seriously, confront women today.

Recent high-resolution and high-cadence observations have surprisingly suggested that prominence barbs exhibit apparent rotating motions suggestive of a tornado-like structure. Additional evidence has been provided by Doppler measurements. The observations reveal opposite velocities for both hot and cool plasma on the two sides of a prominence barb. This motion is persistent for several hours and has been interpreted in terms of rotational motion of prominence feet. Several authors suggest that such barb motions are rotating helical structures around a vertical axis similar to tornadoes on Earth. One of the difficulties of such a proposal is how to support cool prominence plasma in almost-vertical structures against gravity. In this work we model analytically a tornado-like structure and try to determine possible mechanisms to support the prominence plasma. We have found that the Lorentz force can indeed support the barb plasma provided the magnetic structure is sufficiently twisted and/or significant poloidal flows are present.

Unintended exposure in radiotherapy: Identification of prominent causes

International Nuclear Information System (INIS)

Boadu, Mary; Rehani, Madan Mohan

2009-01-01

Background and purpose: Unintended exposures in radiotherapy are likely to occur when certain conditions that favour such exposures exist. Based on the frequency of occurrence of various causes of 100 events of unintended exposures in radiotherapy as derived from the analysis of published reports, a checklist for assessing the vulnerability of radiotherapy facilities for potential accidents has been prepared. The list presents items to be considered for safety critical assessments of a radiotherapy department for the improvement of patient safety and the entire radiotherapy processes. Materials and methods: The resources used for this paper consist of 100 unintended radiotherapy exposures and were derived from existing published reports. The analysis was performed by forming two templates: one consisting of 10 initiating events and another of 35 contributing factors. Results: Four most prominent initiating events were identified and together accounted for about 70% of all the unintended exposure events. Ten most prominent contributing factors were also identified and together accounted for about 70% of all the radiotherapy unintended exposure events covered under this study. Conclusion: With this knowledge of high frequency of occurrences, the identified four prominent initiating events and the 10 most prominent contributing factors must be checked and dealt with as a matter of priority when assessing the safety of a radiotherapy facility. A simple checklist for checking the quality assurance programmes of a radiotherapy department for every aspect of the design and delivery of radiation have been provided.

"Womanhood does not reside in documentation": Queer and feminist student activism for transgender women's inclusion at women's colleges.

Science.gov (United States)

Weber, Shannon

2016-01-01

This article considers queer-driven student activism at Smith College, as well as admissions policy shifts at a number of prominent U.S. women's colleges for transgender women's inclusion. The author illustrates how student attempts to dismantle the transmisogyny at Smith as a purportedly feminist "women's" space, as well as some women's colleges' shifts in admissions policy, challenge divisions between transgender and cisgender women. This paradigmatic shift reflects the campuses as comparative havens for gender and sexual exploration, the influence of postmodern gender theory in understanding identity, and the growth of "queer" as an all-encompassing signifier for sexual and gender transgression.

Piecewise mass flows within a solar prominence observed by the New Vacuum Solar Telescope

Science.gov (United States)

Li, Hongbo; Liu, Yu; Tam, Kuan Vai; Zhao, Mingyu; Zhang, Xuefei

2018-06-01

The material of solar prominences is often observed in a state of flowing. These mass flows (MF) are important and useful for us to understand the internal structure and dynamics of prominences. In this paper, we present a high resolution Hα observation of MFs within a quiescent solar prominence. From the observation, we find that the plasma primarily has a circular motion and a downward motion separately in the middle section and legs of the prominence, which creates a piecewise mass flow along the observed prominence. Moreover, the observation also shows a clear displacement of MF's velocity peaks in the middle section of the prominence. All of these provide us with a detailed record of MFs within a solar prominence and show a new approach to detecting the physical properties of prominence.

Cylindrical prominences and the magnetic influence of the photospheric boundary

International Nuclear Information System (INIS)

Lerche, I.; Chicago Univ., IL; Low, B.C.

1980-01-01

We construct exact, non-linear, solutions for an horizontal, cylindrical, current-carrying, prominence supported against solar gravity by the action of a Lorentz force. The solutions incorporate the photosphere boundary condition, proposed by van Tend and Kuperus (1978), and analyzed by them for line filaments. Our solutions have finite radius for the prominence material and, as well as satisfying the equations of magnetostatic equilibrium, they allow for the continuity of gas pressure, and of the normal and tangential components of magnetic field across the circular prominence boundary. We show that an infinity of solutions is possible and we illustrate the basic behavior by investigation of a special case. We also give a prescription for constructing equilibrium fields for any horizontal prominence with arbitrary cross-section and with an arbitrary external magnetic field. The prescription is ideally suited for numerical codes and we suggest that both the equilibrium of such shapes can easily be accomplished numerically together with their evolutionary history.

"Eugenics talk" and the language of bioethics.

Science.gov (United States)

Wilkinson, S

2008-06-01

In bioethical discussions of preimplantation genetic diagnosis and prenatal screening, accusations of eugenics are commonplace, as are counter-claims that talk of eugenics is misleading and unhelpful. This paper asks whether "eugenics talk", in this context, is legitimate and useful or something to be avoided. It also looks at the extent to which this linguistic question can be answered without first answering relevant substantive moral questions. Its main conclusion is that the best and most non-partisan argument for avoiding eugenics talk is the Autonomy Argument. According to this, eugenics talk per se is not wrong, but there is something wrong with using its emotive power as a means of circumventing people's critical-rational faculties. The Autonomy Argument does not, however, tell against eugenics talk when such language is used to shock people into critical-rational thought. These conclusions do not depend on unique features of eugenics: similar considerations apply to emotive language throughout bioethics.

Is talking to yourself thinking?

Science.gov (United States)

Rachlin, Howard

2018-01-01

The question whether talking to yourself is thinking is considered from two viewpoints: radical behaviorism and teleological behaviorism. For radical behaviorism, following Skinner (1945), mental events such as 'thinking' may be explained in terms of private behavior occurring within the body, ordinarily unobservable by other people; thus, radical behaviorism may identify talking to yourself with thinking. However, to be consistent with its basic principles, radical behaviorism must hold that private behavior, hence thinking, is identical with covert muscular, speech movements (rather than proprioception of those movements). For teleological behaviorism, following Skinner (1938), all mental terms, including 'thinking,' stand for abstract, temporally extended patterns of overt behavior. Thus, for teleological behaviorism, talking to yourself, covert by definition, cannot be thinking. © 2017 Society for the Experimental Analysis of Behavior.

A Discourse Perspective of Topic-prominence in Chinese EFL Learners’ Interlanguage

Directory of Open Access Journals (Sweden)

Shaopeng Li

2014-07-01

Full Text Available The present study aims to investigate the general characteristics of topic-prominent typological interlanguage development of Chinese learners of English in terms of acquiring subject-prominent English structures from the discourse perspective. We have selected as the research target “topic chain” which is the main topic-prominent structure in Chinese discourse and “zero anaphora” which is the most common topic anaphor of topic chain. Topic structures mainly appear in Chinese discourse in the form of “topic chain” (Wang, 2002; 2004. Actually, in the event of a topic chain, research on topic structures should go into the typical range of discourse. Two important findings were yielded by the present study. First, the characteristics of Chinese topic chain are transferrable to the interlanguage of Chinese EFL learners, thus resulting in overgeneralization of zero anaphora; second, interlanguage discourse of Chinese EFL learners reflects the characteristics of a second language acquisition process from topic-prominence to subject-prominence, thus lending support to the discourse transfer hypothesis.

Prominence Bubbles and Plumes: Thermo-magnetic Buoyancy in Coronal Cavity Systems

Science.gov (United States)

Berger, Thomas; Hurlburt, N.

2009-05-01

The Hinode/Solar Optical Telescope continues to produce high spatial and temporal resolution images of solar prominences in both the Ca II 396.8 nm H-line and the H-alpha 656.3 nm line. Time series of these images show that many quiescent prominences produce large scale (50 Mm) dark "bubbles" that "inflate" into, and sometimes burst through, the prominence material. In addition, small-scale (2--5 Mm) dark plumes are seen rising into many quiescent prominences. We show typical examples of both phenomena and argue that they originate from the same mechanism: concentrated and heated magnetic flux that rises due to thermal and magnetic buoyancy to equilibrium heights in the prominence/coronal-cavity system. More generally, these bubbles and upflows offer a source of both magnetic flux and mass to the overlying coronal cavity, supporting B.C. Low's theory of CME initiation via steadily increasing magnetic buoyancy breaking through the overlying helmut streamer tension forces. Quiescent prominences are thus seen as the lowermost parts of the larger coronal cavity system, revealing through thermal effects both the cooled downflowing "drainage" from the cavity and the heated upflowing magnetic "plasmoids" supplying the cavity. We compare SOT movies to new 3D compressible MHD simulations that reproduce the dark turbulent plume dynamics to establish the magnetic and thermal character of these buoyancy-driven flows into the corona.

Modeling of prominence threads in magnetic fields: Levitation by incompressible MHD waves

Science.gov (United States)

Pécseli, Hans; Engvold, OddbjØrn

2000-05-01

The nature of thin, highly inclined threads observed in quiescent prominences has puzzled solar physicists for a long time. When assuming that the threads represent truly inclined magnetic fields, the supporting mechanism of prominence plasma against gravity has remained an open issue. This paper examines the levitation of prominence plasma exerted by weakly damped MHD waves in nearly vertical magnetic flux tubes. It is shown that the wave damping, and resulting `radiation pressure', caused predominantly by ion-neutral collisions in the `cold' prominence plasma, may balance the acceleration of gravity provided the oscillation frequency is ω~ 2 rad s^-1 (f~0.5 Hz). Such short wave periods may be the result of small-scale magnetic reconnections in the highly fragmentary magnetic field of quiescent prominences. In the proposed model, the wave induced levitation acts predominantly on plasma - neutral gas mixtures.

In the book Their Day in the Sun, Ruth Howes and Caroline Herzenberg documented more than 1000 women who worked on the Manhattan Project, preserving their legacy for generations to come. At the 2009 Chicago meeting, the AAPT Committee on Women in Physics celebrated the accomplishments of these women and the men who worked beside them. Howes presented an overview of the contributions of women to the development of the first nuclear weapon, and the session was honored with talks from two Manhattan project veterans, Ellen Cleminshaw Weaver, who worked at Oak Ridge, and Dorothy Marcus Gans, who worked as a technician in the Metallurgical Laboratory in Chicago. I will present a summary of the session, analyzing the effect of working on the project on the career trajectories of the women involved, and point listeners toward additional documentation of this history.

2017-11-01

Speech is a complex function in humans, but the linguistic characteristics of sleep talking are unknown. We analyzed sleep-associated speech in adults, mostly (92%) during parasomnias. The utterances recorded during night-time video-polysomnography were analyzed for number of words, propositions and speech episodes, frequency, gaps and pauses (denoting turn-taking in the conversation), lemmatization, verbosity, negative/imperative/interrogative tone, first/second person, politeness, and abuse. Two hundred thirty-two subjects (aged 49.5 ± 20 years old; 41% women; 129 with rapid eye movement [REM] sleep behavior disorder and 87 with sleepwalking/sleep terrors, 15 healthy subjects, and 1 patient with sleep apnea speaking in non-REM sleep) uttered 883 speech episodes, containing 59% nonverbal utterance (mumbles, shouts, whispers, and laughs) and 3349 understandable words. The most frequent word was "No": negations represented 21.4% of clauses (more in non-REM sleep). Interrogations were found in 26% of speech episodes (more in non-REM sleep), and subordinate clauses were found in 12.9% of speech episodes. As many as 9.7% of clauses contained profanities (more in non-REM sleep). Verbal abuse lasted longer in REM sleep and was mostly directed toward insulting or condemning someone, whereas swearing predominated in non-REM sleep. Men sleep-talked more than women and used a higher proportion of profanities. Apparent turn-taking in the conversation respected the usual language gaps. Sleep talking parallels awake talking for syntax, semantics, and turn-taking in conversation, suggesting that the sleeping brain can function at a high level. Language during sleep is mostly a familiar, tensed conversation with inaudible others, suggestive of conflicts. © Sleep Research Society 2017.

Jonason, Peter K; Betteridge, Gabrielle L; Kneebone, Ian I

2016-01-01

Using a mixed-methods study, we provided the first systematic documentation and exploration of erotic talk. In Study 1 (N = 95), participants provided 569 erotic talk statements in an anonymous online survey, which we classified, using a modified thematic analysis, as being representative of eight themes. In Study 2 (N = 238), we quantified individual differences in these themes, subjected them to factor analysis, and examined the nomological network surrounding them with measures of relationship and sexual satisfaction, sociosexuality, and personality. The eight initial categories represented two higher order factors, which we call individualist talk and mutualistic talk. These factors were orthogonal in factor analysis and distinct in their nomological network. While the majority of people reported using erotic talk, we found few sex differences in its use.

Talking the Talk: The Construction of Activist Capital in Argentinian Popular Social Movements

Directory of Open Access Journals (Sweden)

María Mercedes Palumbo

2018-05-01

Full Text Available This article analyzes the socialization and construction of social and political capital in popular movements in the Metropolitan Area of Buenos Aires, Argentina. To analyze this case, we employ a theoretical framework which draws on the concepts of activist social capital and political socialization. These concepts serve to illuminate the native Argentinian concept of “talking the talk”, which is a key skill that contributes to the construction of one’s social capital as an activist. We argue that this know how is particularly important in determining one’s trajectory as an activist. However, understanding how to employ political discourse requires the adoption of a gender lens given that the mastery of “talking the talk” represents a greater challenge for female activists who have to overcome the impossibility of speaking. The reflections developed in this article problematize the everyday politics and practices of popular social movements given that the know-how of “talking the talk” contributes to the crystallization of the gendered social division of labor in social movements.

Scientifically speaking: Identifying, analyzing, and promoting science talk in small groups

Science.gov (United States)

Holthuis, Nicole Inamine

In this dissertation I define, document, and analyze the nature of students' science talk as they work in cooperative learning groups. Three questions form the basis of this research. First, what is science talk? Second, how much and what kind of science talk did students do? And, third, what conditions help promote or inhibit students' science talk? This study was conducted in a total of six classrooms in three high schools. I videotaped and audiotaped students as they worked in small groups during the course of an ecology unit. I analyzed this videotape data and field notes using both quantitative and qualitative methods. I define science talk as talk that serves to move students along in terms of the science (both content and process) required or suggested by the activity. More specifically, I identified five epistemological characteristics that delineate what counts as scientific knowledge and, subsequently, science talk. From this definition, I developed an analytic framework and science talk observation instrument to document the quantity and level of student and teacher talk during groupwork. Analysis of the data from this instrument indicates that the overall level of students' science talk is considerable and students do significantly more science talk than school talk. I also found that while the overall level and type of science talk does not vary by class or by school, it does vary by activity type. Finally, my analysis suggests that science talk does not vary by gender composition of the group. I explored the classroom conditions that promote or inhibit science talk during groupwork. My findings suggest that, among other things, teachers can promote science talk by delegating authority to students, by emphasizing content and the big idea, by implementing open-ended tasks, and by modeling science talk. In conclusion, the findings described in this dissertation point teachers and researchers toward ways in which they may improve practice in order to

Women and Ultramodern Buddhism in Australia

Directory of Open Access Journals (Sweden)

Anna Halafoff

2018-05-01

Full Text Available Buddhists started arriving in Australia in large numbers during the mid-1800s, and the first Buddhist societies and centres began to be formed in the mid-late 1900s. This paper examines the role of women in bringing Buddhism to and establishing it in Australia. Women have featured prominently in a small amount of scholarship, including Paul Croucher’s (1989 Buddhism in Australia: 1848–1988 and Cristina Rocha and Michelle Barker’s (eds. 2011 edited volume on Buddhism in Australia: Traditions in Change. This paper draws on these sources, but primarily on more recent digital oral histories of prominent Buddhist women and men in Australia, recorded as part of the first stage of the Buddhist Life Stories of Australia project in 2014–2015. These first-hand accounts bring the early female pioneers of Buddhism in Australia to life and provide a rich re-telling of this history with emphasis on women’s contributions to it. We also argue that these women’s experiences can best be understood through a framework of ‘ultramodern Buddhism,’ built upon theories of modern and post-modern Buddhism, as many of these women were trailblazers bridging dualisms of tradition and modernity, Asia and the West, and adhering to both feminist and Buddhist principles.

Family food talk, child eating behavior, and maternal feeding practices.

2017-10-01

Families discuss food and eating in many ways that may shape child eating habits. Researchers studying how families talk about food have examined this process during meals. Little work has examined parent-child food-related interactions outside of mealtime. We assessed family food talk at home outside of mealtime and tested whether food talk was associated with obesogenic child eating behaviors, maternal feeding practices, or child weight. Preschool and school-aged mother-child dyads (n = 61) participated in naturalistic voice recording using a LENA (Language ENvironment Analysis) recorder. A coding scheme was developed to reliably characterize different types of food talk from LENA transcripts. Mothers completed the Children's Eating Behavior Questionnaire (CEBQ) and Child Feeding Questionnaire (CFQ) to assess child eating behaviors and maternal feeding practices. Child weight and height were measured and body mass index z-score (BMIz) calculated. Bivariate associations among food talk types, as a proportion of total speech, were examined and multivariate regression models used to test associations between food talk and child eating behaviors, maternal feeding practices, and child BMIz. Proportion of child Overall Food Talk and Food Explanations were positively associated with CEBQ Food Responsiveness and Enjoyment of Food (p's < 0.05). Child food Desire/Need and child Prep/Planning talk were positively associated with CEBQ Enjoyment of Food (p < 0.05). Child Food Enjoyment talk and mother Overt Restriction talk were positively associated with CEBQ Emotional Over-Eating (p < 0.05). Mother Monitoring talk was positively associated with CFQ Restriction (p < 0.05). Mother Prep/Planning talk was negatively associated with child BMIz. Food talk outside of mealtimes related to child obesogenic eating behaviors and feeding practices in expected ways; examining food talk outside of meals is a novel way to consider feeding practices and child eating behavior

Gender parity trends for invited speakers at four prominent virology conference series.

Science.gov (United States)

Kalejta, Robert F; Palmenberg, Ann C

2017-06-07

Scientific conferences are most beneficial to participants when they showcase significant new experimental developments, accurately summarize the current state of the field, and provide strong opportunities for collaborative networking. A top-notch slate of invited speakers, assembled by conference organizers or committees, is key to achieving these goals. The perceived underrepresentation of female speakers at prominent scientific meetings is currently a popular topic for discussion, but one that often lacks supportive data. We compiled the full rosters of invited speakers over the last 35 years for four prominent international virology conferences, the American Society for Virology Annual Meeting (ASV), the International Herpesvirus Workshop (IHW), the Positive-Strand RNA Virus Symposium (PSR), and the Gordon Research Conference on Viruses & Cells (GRC). The rosters were cross-indexed by unique names, gender, year, and repeat invitations. When plotted as gender-dependent trends over time, all four conferences showed a clear proclivity for male-dominated invited speaker lists. Encouragingly, shifts toward parity are emerging within all units, but at different rates. Not surprisingly, both selection of a larger percentage of first time participants and the presence of a woman on the speaker selection committee correlated with improved parity. Session chair information was also collected for the IHW and GRC. These visible positions also displayed a strong male dominance over time that is eroding slowly. We offer our personal interpretation of these data to aid future organizers achieve improved equity among the limited number of available positions for session moderators and invited speakers. IMPORTANCE Politicians and media members have a tendency to cite anecdotes as conclusions without any supporting data. This happens so frequently now, that a name for it has emerged: fake news. Good science proceeds otherwise. The under representation of women as invited

Motions in Prominence Barbs as observed by Hinode/SOT and IRIS

Science.gov (United States)

Kucera, Therese A.; Ofman, Leon; Tarbell, Theodore D.

2016-05-01

We discuss observations of prominence barb dynamics as observed by Hinode/SOT and IRIS. Prominence barbs extend outwards to the side of the main prominence spine and downwards towards the chromosphere. Their properties, including the structure of their magnetic field and the nature of the motions observed in them are a subject of current debate. We use a combination of high cadence, high resolution imaging, H-alpha Doppler, and Mg II line profile data to analyze and understand waves and flows in barbs and discuss their ramifications in terms of a model of the barb magnetic field as collection of dipped field lines.

At which height is a prominence inclined to be unstable, or where is the most probable critical height for the prominence destabilization? This question was statistically studied based on 362 solar limb prominences well recognized by Solar Limb Prominence Catcher and Tracker from 2007 April to the end of 2009. We found that there are about 71% disrupted prominences (DPs), among which about 42% of them did not erupt successfully and about 89% of them experienced a sudden destabilization process. After a comprehensive analysis of the DPs, we discovered the following: (1) Most DPs become unstable at a height of 0.06-0.14 R{sub Sun} from the solar surface, and there are two most probable critical heights at which a prominence is very likely to become unstable, the first one is 0.13 R{sub Sun} and the second one is 0.19 R{sub Sun }. (2) An upper limit for the erupting velocity of eruptive prominences (EPs) exists, which decreases following a power law with increasing height and mass; accordingly, the kinetic energy of EPs has an upper limit too, which decreases as the critical height increases. (3) Stable prominences are generally longer and heavier than DPs, and not higher than 0.4 R{sub Sun }. (4) About 62% of the EPs were associated with coronal mass ejections (CMEs); but there is no difference in apparent properties between EPs associated with CMEs and those that are not.

We investigate the properties of a “solar tornado” observed on 2014 July 15, and aim to link the behavior of the plasma to the internal magnetic field structure of the associated prominence. We made multi-wavelength observations with high spatial resolution and high cadence using SDO/AIA, the Interface Region Imaging Spectrograph (IRIS) spectrograph, and the Hinode/Solar Optical Telescope (SOT) instrument. Along with spectropolarimetry provided by the Télescope Héliographique pour l’Etude du Magnétisme et des Instabilités Solaires telescope we have coverage of both optically thick emission lines and magnetic field information. AIA reveals that the two legs of the prominence are strongly absorbing structures which look like they are rotating, or oscillating in the plane of the sky. The two prominence legs, which are both very bright in Ca ii (SOT), are not visible in the IRIS Mg ii slit-jaw images. This is explained by the large optical thickness of the structures in Mg ii, which leads to reversed profiles, and hence to lower integrated intensities at these locations than in the surroundings. Using lines formed at temperatures lower than 1 MK, we measure relatively low Doppler shifts on the order of ±10 km s{sup −1} in the tornado-like structure. Between the two legs we see loops in Mg ii, with material flowing from one leg to the other, as well as counterstreaming. It is difficult to interpret our data as showing two rotating, vertical structures that are unrelated to the loops. This kind of “tornado” scenario does not fit with our observations. The magnetic field in the two legs of the prominence is found to be preferentially horizontal.

American Association of Physical Anthropologists (AAPA) membership surveys from 1996 and 1998 revealed significant gender disparities in academic status. A 2014 follow-up survey showed that gender equality had improved, particularly with respect to the number of women in tenure-stream positions. However, although women comprised 70% of AAPA membership at that time, the percentage of women full professors remained low. Here, we continue to consider the status of women in biological anthropology by examining the representation of women through a quantitative analysis of their participation in annual meetings of the AAPA during the past 20 years. We also review the programmatic goals of the AAPA Committee on Diversity Women's Initiative (COD-WIN) and provide survey results of women who participated in COD-WIN professional development workshops. Finally, we examine the diversity of women's career paths through the personal narratives of 14 women biological anthropologists spanning all ranks from graduate student to Professor Emeritus. We find that over the past 20 years, the percentage of women first authors of invited symposia talks has increased, particularly in the sub-disciplines of bioarchaeology, genetics, and paleoanthropology. The percentage of women first authors on contributed talks and posters has also increased. However, these observed increases are still lower than expected given the percentage of graduate student women and women at the rank of assistant and associate professor. The personal narratives highlight first-hand the impact of mentoring on career trajectory, the challenges of achieving work-life satisfaction, and resilience in the face of the unexpected. We end with some suggestions for how to continue to improve equality and equity for women in biological anthropology. © 2018 American Association of Physical Anthropologists.

Non-LTE hydrogen-line formation in moving prominences

Science.gov (United States)

Heinzel, P.; Rompolt, B.

1986-01-01

The behavior of hydrogen-line brightness variations, depending on the prominence-velocity changes were investigated. By solving the NON-Local thermodynamic equilibrium (LTE) problem for hydrogen researchers determine quantitatively the effect of Doppler brightening and/or Doppler dimming (DBE, DDE) in the lines of Lyman and Balmer series. It is demonstrated that in low-density prominence plasmas, DBE in H alpha and H beta lines can reach a factor of three for velocities around 160 km/sec, while the L alpha line exhibits typical DDE. L beta brightness variations follow from a combined DBE in the H alpha and DDE in L alpha and L beta itself, providing that all relevant multilevel interlocking processes are taken into account.

How Ad-talk and Word-of-Mouth Influence Consumers’ Responses

DEFF Research Database (Denmark)

Martensen, Anne; Mouritsen, Jan

2014-01-01

This study investigates: (a) if consumers talk about advertizing messages – ad-talk – is a new, distinct concept that differs from word-of-mouth (WOM) communication in definition and impact; (b) how ad-talk mobilizes WOM; (c) how WOM mediates the relationship between ad-talk and consumer responses....... A new model is developed that adapts the classic Theory of Reasoned Action (TRA) framework by replacing the social norm with consumers’ ad-talk and WOM. Two large scale internet surveys are conducted to test and validate the model. Findings show that ad-talk and WOM are two different social processes....... Ad-talk only mobilizes PWOM. PWOM mediates and leverages ad-talk’s influence on consumer responses, because PWOM adds personal experiences, preferences and social acceptance to the brand promise seen in the firm’s advertizing. This changes the value of the brand and makes the firm’s offer better than...

Girls Talk Math - Engaging Girls Through Math Media

``Girls Talk Math: Engaging Girls through Math Media'' is a free two-week long summer day camp for high-school girls in the Triangle area of NC. This past June the camp had its second run thanks to renewed funding from the Mathematical Association of America Tensor Women and Mathematics Grant. The camp involved 35 local high-school students who identify as female. Campers complete challenging problem sets and research the life of a female scientist who worked on similar problems. They report their work in a blog post and record a podcast about the scientist they researched. The curriculum has been developed by Mathematics graduate students at UNC from an inquiry based learning perspective; problem sets topics include some theoretical mathematics, but also more applied physics-based material. Campers worked on fluid dynamics, special relativity, and quantum mechanics problem sets which included experiments. The camp has received positive feedback from the local community and the second run saw a large increase in the number of participants. The program is evaluated using pre and post surveys, which measure campers' confidence and interest in pursuing higher level courses in STEM. The results from the past two summers have been encouraging. Mathematical Association of America Tensor Women and Mathematics Grant.

Mental state talk by Danish preschool children

Directory of Open Access Journals (Sweden)

Ane Knüppel

2008-02-01

Full Text Available Sixteen 4 to 6-year-old Danish children were video-recorded, while interacting spontaneously with their family in their homes. The mental state talk of the children was identified and analysed with respect to three mental domains: desire, feeling and cognition, and was compared to data from a similar study carried out with Canadian families (Jenkins et al., 2003. Our results suggest some cross-cultural differences in children’s mental state talk. First, Danish children produce a larger variation of mental state talk words than Canadian children do, and second, the distribution of mental state talk across the three domains differed for the two language groups. Semantic variation between Danish and English was identified in the study, which may partly explain the findings. Furthermore we present a usage-based approach to the investigation of children’s development of psychological categories in language as well as cross-linguistically.

The systematic rape of women in Bosnia-Herzegovina, direct attacks upon women as part of the genocide in Rwanda, and the recently revealed stories of Korean and Filipino “comfort women” during the Second World War assaulted us with the vulnerability and dangers which women face in war-generated violence. However, such violence, although often in the news, is sadly only a fraction of the vio...

Reasons Why Some Women Quit Science

Science.gov (United States)

Tabazadeh, A.

2002-12-01

Nearly half of all graduate students majoring in various disciplines of science today are women, yet men still predominate the faculty makeup at most universities and research institutions. This issue was discussed at length last year in the journal Science and also in the Chemical Engineering News (the ACS weekly publication magazine). The question is: why do so many women decide to major in science but not to pursue a career in science? Over the years I have seen highly capable women quit science for two main reasons. First, intimidation that can be very difficult to deal with when someone is just starting a career in science. Thus, I encourage young women to make a sincere effort to surround themselves with colleagues who are both knowledgeable and considerate. Keep in my mind that you have a choice to choose your future collaborators, so make some smart choices early on and throughout your career. Second, is the need to balance the demands of work with those of family life. Personally, I don't believe a tenure system is fair to young women who wish to have children during this appointment. The level of stress can be very high, which prevents women from applying to a position where they are given only a few short years to prove themselves. Also, try not to make a radical decision (i.e. quit science) if you are too stressed. Talk to more senior women in the field to learn how to better deal with your stress. After all a career in science has many ups and downs, and to survive, one needs to balance the good and bad days. In this talk I will address the questions outlined in the announcement as they relate to me. Overall, my advice to young women who are just starting their scientific careers is to celebrate your accomplishments and learn from your mistakes.

Marshak Lectureship Talk: Women in Physics in the Baltic States Region: Problems and Solutions

Science.gov (United States)

Satkovskiene, Dalia

2008-03-01

In this contribution the gender equality problem in physics will be discussed on the basis of the results obtained implementing the project ``Baltic States Network: Women in Sciences and High Technology'' (BASNET) initiated by Lithuanian women physicists and financed by European Commission. The main goal of BASNET project was creation of the regional Strategy how to deal with women in sciences problem in the Baltic States. It has some stages and the contribution follows them. The first one was in depth sociological study aiming to find out disincentives and barriers women scientists face in their career and work at science and higher education institutions. Analysis of results revealed wide range of problems concerned with science organization, management and financing common for both counterparts. However it also proved the existence of women discrimination in sciences. As main factors influencing women under-representation in Physics was found: the stereotypes existing in the society where physics is assigned to the masculine area of activity; failings of the science management system, where highest positions are distributed not using the institutionalized objective criteria but by voting, where the correctness of majority solutions is anticipated implicitly. In physics where male scientists are the majority (they also usually compose executive boards, committees etc.) results of such a procedures often are unfavorable for women. The same reasons also influence women ``visibility'' in physicist's community and as the consequence possibility to receive needed recourses for their research as well as appropriate presentation of results obtained. The study revealed also the conservatism of scientific community- reluctance to face existing in the scientific society problems and to start solving them. On the basis of the results obtained as well practice of other countries the common strategy of solving women in physics (sciences) in the Baltic States region was

PATTERNS OF FLOWS IN AN INTERMEDIATE PROMINENCE OBSERVED BY HINODE

International Nuclear Information System (INIS)

Ahn, Kwangsu; Chae, Jongchul; Cao Wenda; Goode, Philip R.

2010-01-01

The investigation of plasma flows in filaments/prominences gives us clues to understanding their magnetic structures. We studied the patterns of flows in an intermediate prominence observed by Hinode/SOT. By examining a time series of Hα images and Ca II H images, we have found horizontal flows in the spine and vertical flows in the barb. Both of these flows have a characteristic speed of 10-20 km s -1 . The horizontal flows displayed counterstreaming. Our detailed investigation revealed that most of the moving fragments in fact reversed direction at the end point of the spine near a footpoint close to the associated active region. These returning flows may be one possible explanation of the well-known counterstreaming flows in prominences. In contrast, we have found vertical flows-downward and upward-in the barb. Most of the horizontal flows in the spine seem to switch into vertical flows when they approach the barb, and vice versa. We propose that the net force resulting from a small deviation from magnetohydrostatic equilibrium, where magnetic fields are predominantly horizontal, may drive these patterns of flow. In the prominence studied here, the supposed magnetohydrostatic configuration is characterized by magnetic field lines sagging with angles of 13 0 and 39 0 in the spine and the barb, respectively.

Extreme-ultraviolet limb spectra of a prominence observed from SKYLAB

International Nuclear Information System (INIS)

Mariska, J.T.; Doschek, G.A.; Feldman, U.

1979-01-01

Line profiles of extreme ultraviolet emission lines observed in a solar prominence at positions above the white-light limb with the NRL slit spectrograph on Skylab are discussed. Absolute line intensities and full widths at half-maximum are presented for lines formed over the temperature range approx.1 x 10 4 to 2.2 x 10 5 K. The volume emission measures calculated using resonance line intensities are greater than quiet-Sun emission measures at the same height above the limb and indicate a somewhat different distribution of material with temperature in the prominence compared to the quiet-Sun emission measure at +8''. Electron densities in the prominence determined using the calculated emission measures and the intensities of density-sensitive intersystem lines are between the quiet-Sun electron density and half the quiet-Sun electron density. Random mass-motion velocities calculated from the measured full widths at half-maximum show a range of velocities. For T/sub e/> or approx. =4 x 10 4 K, the nonthermal velocity decreases with increasing height in the prominence. For T/sub e/ 4 K, the calculated mass motions are near zero. From the He II 1640 A line profile we derive an average temperature of 27,000 K for the region in which He II is emitted

Frequency and Efficacy of Talk-Related Tasks in Primary Science

Science.gov (United States)

Braund, Martin; Leigh, Joanne

2013-04-01

Pupil talk and discussion are seen as having important social and cognitive outcomes. In science classes, pupils' collaborative talk supports the construction of meaning and helps examine the status of evidence, theory and knowledge. However, pupil interactive talk in groups is rare in science lessons. The research reported is part of a project to increase the amount of pupil-pupil talk in primary schools through a programme of teaching and professional development. Pupils' self-reports of the frequency and learning efficacies of talk related activities in science lessons were collected before and after a programme of teaching in 24 schools in one of the most socially and educationally deprived areas of England. Findings showed pupils valued talking about their ideas over listening to those of other pupils. Science talk frequency (STF) was closely correlated with science talk efficacy (STE) and both were positively correlated with pupils' attitudes to school science. Analysis of covariance (ANCOVA) of the correlation of STF with STE showed values were independent of gender and ability but that school experience was a significant factor. After the teaching programme and, contrary to expectations, the frequency of talk activities in science lessons appeared to have decreased but varied according to class grades. The degree of correlation between STF and STE was stronger after the teaching in over half of the schools. Schools where STF/STE strengthened most as a result of teaching were those involved in an additional initiative to use modelled talk related to industrial contexts.

Talk of time

Directory of Open Access Journals (Sweden)

Johann-Albrecht Meylahn

2015-06-01

Full Text Available Maybe, before we speak of time, or maybe whilst we are speaking of time, or maybe after we have spoken of time, in the various modes of time’s insistence to exist, one should give time to the talk of time. There are various different modes of time’s insistence to exist, such as quantum physics in conversation with relativity theory where time is constructed as a fourth dimension of space. Or there are the modes of time in history, religion, psychology and philosophy, and each of these modes is composed, and composes its own specific object called time, and a particular subject who understands and interprets time in that particular mode. Yet, before, whilst or after these modes of time’s insistence to exist, one should maybe give time to time’s time. Give time for the various times to articulate themselves in the various modes of existence, thereby creating both a whole plurality of differing subjects, as well as plurality of differing objects, all called ‘time’. Once time has been given time to talk its talk, to articulate itself within the various modes, it will be interrupted by the articulations of time in various modes of time still to come. These disruptions of time by time always still to come opens the door for a theological narrative – a narrative on time, but created by the coming of messianic times, interpreted in the mode of hope but also in the mode of a promise from the past.

Modelling and Analysis of Biochemical Signalling Pathway Cross-talk

Directory of Open Access Journals (Sweden)

Robin Donaldson

2010-02-01

Full Text Available Signalling pathways are abstractions that help life scientists structure the coordination of cellular activity. Cross-talk between pathways accounts for many of the complex behaviours exhibited by signalling pathways and is often critical in producing the correct signal-response relationship. Formal models of signalling pathways and cross-talk in particular can aid understanding and drive experimentation. We define an approach to modelling based on the concept that a pathway is the (synchronising parallel composition of instances of generic modules (with internal and external labels. Pathways are then composed by (synchronising parallel composition and renaming; different types of cross-talk result from different combinations of synchronisation and renaming. We define a number of generic modules in PRISM and five types of cross-talk: signal flow, substrate availability, receptor function, gene expression and intracellular communication. We show that Continuous Stochastic Logic properties can both detect and distinguish the types of cross-talk. The approach is illustrated with small examples and an analysis of the cross-talk between the TGF-b/BMP, WNT and MAPK pathways.

EVIDENCE FOR ROTATIONAL MOTIONS IN THE FEET OF A QUIESCENT SOLAR PROMINENCE

International Nuclear Information System (INIS)

Orozco Suárez, D.; Asensio Ramos, A.; Trujillo Bueno, J.

2012-01-01

We present observational evidence of apparent plasma rotational motions in the feet of a solar prominence. Our study is based on spectroscopic observations taken in the He I 1083.0 nm multiplet with the Tenerife Infrared Polarimeter attached to the German Vacuum Tower Telescope. We recorded a time sequence of spectra with 34 s cadence placing the slit of the spectrograph almost parallel to the solar limb and crossing two feet of an intermediate size, quiescent hedgerow prominence. The data show opposite Doppler shifts, ±6 km s –1 , at the edges of the prominence feet. We argue that these shifts may be interpreted as prominence plasma rotating counterclockwise around the vertical axis to the solar surface as viewed from above. The evolution of the prominence seen in EUV images taken with the Solar Dynamics Observatory provided us with clues to interpret the results as swirling motions. Moreover, time-distance images taken far from the central wavelength show plasma structures moving parallel to the solar limb with velocities of about 10-15 km s –1 . Finally, the shapes of the observed intensity profiles suggest the presence of, at least, two components at some locations at the edges of the prominence feet. One of them is typically Doppler shifted (up to ∼20 km s –1 ) with respect to the other, thus suggesting the existence of supersonic counter-streaming flows along the line of sight.

Full Text Available In this analysis we have chosen a recent French talk show to illustrate how communication is turned into some new kind of "ideology"nowadays: in other words, you have to communicate if you consider yourself a citizen of today's world. The main characteristic of issue-centered talk shows being the destabilization of the implicit rules and participation framework, we observe how the so-called democratic right to express ourselves is (misused by the talk show host to secure the dynamics of the show. In order to reveal the host's manipulations, we have examined the verbal interactions between host and guests on the following issues: topic choice, turn-taking mechanisms and identity construction of the talk show's guests. In the perspective that this kind of talk show presents itself as a public space where direct democracy can be exercised, the analysis of the discursive strategies of the talk show host reveals the impact of a mediatic participation framework.Para a presente análise escolhemos um "talk show" francês recente para ilustrar como a comunicação se transforma em um novo tipo de ideologia: em outras palavras, você deve se comunicar se você se considera um cidadão do mundo de hoje. Sendo a principal característica do talk show a desestabilização das regras implícitas e o framework de participação, observamos como o tal direito democrático de expressão é interpretado pelo apresentador para manter a dinâmica do programa. Para revelar suas manipulações, examinamos as interações verbais entre apresentador e convidados nos seguintes temas: escolha do tópico, mecanismos de tomada de turno e construção de identidade dos convidados. É nessa perspectiva que este tipo de programa se apresenta como um espaço público onde a democracia direta pode ser exercitada; a análise das estratégias discursivas do apresentador do talk show revela o impacto de um framework de participação mediada.

Kreinin, Anatoly; Krishtul, Vladimir; Kirsh, Zvi; Menuchin, Michael

2015-01-01

Though hallucinations and delusions are prominent basic impairments in schizophrenia, reports of the relationship between hallucinatory and delusional symptoms among schizophrenia patients are scant. To examine the epidemiological and clinical differences between mainly hallucinatory and mainly delusional subgroups of paranoid schizophrenia patients. One hundred schizophrenia patients, paranoid type, were recruited. In a cross-sectional study, participants were divided into Mainly Hallucinatory (H) and Mainly Delusional (D) subgroups. Demographic variables were compared and clinical characteristics were evaluated using the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, and the Clinical Global Impression Scale. The Quality-of-Life Enjoyment and Satisfaction Questionnaire-18 was used to assess quality of life. Clinically, the H group was more heterogeneous as expressed by the broader range of scores that described the clinical picture of patients in that subgroup (in 43 of 78 variables, 55.13%) and similar ranges of scores (31 of 78 variables, 39.74%) for patients in the D group. Duration of hospitalization was significantly longer in group H than in group D (p=0.047). There was no statistically significant difference between the H and D subgroups in demographic characteristics. There are distinct epidemiological and clinical differences between the H and D subgroups, with more severe positive and negative symptoms and greater functional impairment in the H group. Paranoid schizophrenia patients with prominent hallucinations have poorer prognosis and need intensive therapeutic rehabilitation beginning with onset-of-illness. Further genetic studies and comparisons of fMRI and/or PET findings are warranted to investigate additional distinctive characteristics of these subgroups.

Characterization of Thermal Cross-talk in a γ-ray Microcalorimeter Array

2009-01-01

We present experimental data describing cross-talk within an array of gamma-ray microcalorimeters during gamma-ray irradiation. The microcalorimeters consist of Mo/Cu transition-edge sensors (TESs) with attached Sn absorbers. We observe both thermal and electrical cross-talk with peak cross-talk amplitudes as large as 0.4%. We have developed an analytical model for thermal cross-talk and make a preliminary comparison to data. Cross-talk must be understood and minimized for high resolution spectroscopy at high input count rates.

The intention is to give a talk on some of the recent BSM results of ATLAS, with occasional reference to CMS. Since no LHC experiment has yet found any BSM physics, the focus on the talk is NOT on listing all the (null) searches that have been conducted. Instead it intends/aims to draw the audience's attention to (1) common features of the searches which have already taken place, (2) common "holes" in those searches (i.e. places where BSM physics can still easily be hiding) and (3) some ideas of where things will go next.

Quiescent Prominence Dynamics Observed with the Hinode Solar Optical Telescope. I. Turbulent Upflow Plumes

Hinode/Solar Optical Telescope (SOT) observations reveal two new dynamic modes in quiescent solar prominences: large-scale (20-50 Mm) "arches" or "bubbles" that "inflate" from below into prominences, and smaller-scale (2-6 Mm) dark turbulent upflows. These novel dynamics are related in that they are always dark in visible-light spectral bands, they rise through the bright prominence emission with approximately constant speeds, and the small-scale upflows are sometimes observed to emanate from the top of the larger bubbles. Here we present detailed kinematic measurements of the small-scale turbulent upflows seen in several prominences in the SOT database. The dark upflows typically initiate vertically from 5 to 10 Mm wide dark cavities between the bottom of the prominence and the top of the chromospheric spicule layer. Small perturbations on the order of 1 Mm or less in size grow on the upper boundaries of cavities to generate plumes up to 4-6 Mm across at their largest widths. All plumes develop highly turbulent profiles, including occasional Kelvin-Helmholtz vortex "roll-up" of the leading edge. The flows typically rise 10-15 Mm before decelerating to equilibrium. We measure the flowfield characteristics with a manual tracing method and with the Nonlinear Affine Velocity Estimator (NAVE) "optical flow" code to derive velocity, acceleration, lifetime, and height data for several representative plumes. Maximum initial speeds are in the range of 20-30 km s-1, which is supersonic for a ~10,000 K plasma. The plumes decelerate in the final few Mm of their trajectories resulting in mean ascent speeds of 13-17 km s-1. Typical lifetimes range from 300 to 1000 s (~5-15 minutes). The area growth rate of the plumes (observed as two-dimensional objects in the plane of the sky) is initially linear and ranges from 20,000 to 30,000 km2 s-1 reaching maximum projected areas from 2 to 15 Mm2.

Osteopontin activates the diabetes-associated potassium channel TALK-1 in pancreatic β-cells.

Directory of Open Access Journals (Sweden)

Matthew T Dickerson

Full Text Available Glucose-stimulated insulin secretion (GSIS relies on β-cell Ca2+ influx, which is modulated by the two-pore-domain K+ (K2P channel, TALK-1. A gain-of-function polymorphism in KCNK16, the gene encoding TALK-1, increases risk for developing type-2 diabetes. While TALK-1 serves an important role in modulating GSIS, the regulatory mechanism(s that control β-cell TALK-1 channels are unknown. Therefore, we employed a membrane-specific yeast two-hybrid (MYTH assay to identify TALK-1-interacting proteins in human islets, which will assist in determining signaling modalities that modulate TALK-1 function. Twenty-one proteins from a human islet cDNA library interacted with TALK-1. Some of these interactions increased TALK-1 activity, including intracellular osteopontin (iOPN. Intracellular OPN is highly expressed in β-cells and is upregulated under pre-diabetic conditions to help maintain normal β-cell function; however, the functional role of iOPN in β-cells is poorly understood. We found that iOPN colocalized with TALK-1 in pancreatic sections and coimmunoprecipitated with human islet TALK-1 channels. As human β-cells express two K+ channel-forming variants of TALK-1, regulation of these TALK-1 variants by iOPN was assessed. At physiological voltages iOPN activated TALK-1 transcript variant 3 channels but not TALK-1 transcript variant 2 channels. Activation of TALK-1 channels by iOPN also hyperpolarized resting membrane potential (Vm in HEK293 cells and in primary mouse β-cells. Intracellular OPN was also knocked down in β-cells to test its effect on β-cell TALK-1 channel activity. Reducing β-cell iOPN significantly decreased TALK-1 K+ currents and increased glucose-stimulated Ca2+ influx. Importantly, iOPN did not affect the function of other K2P channels or alter Ca2+ influx into TALK-1 deficient β-cells. These results reveal the first protein interactions with the TALK-1 channel and found that an interaction with iOPN increased �

Prominence Bubble Shear Flows and the Coupled Kelvin-Helmholtz — Rayleigh-Taylor Instability

Science.gov (United States)

Berger, Thomas; Hillier, Andrew

2017-08-01

Prominence bubbles are large arched structures that rise from below into quiescent prominences, often growing to heights on the order of 10 Mm before going unstable and generating plume upflows. While there is general agreement that emerging flux below pre-existing prominences causes the structures, there is lack of agreement on the nature of the bubbles and the cause of the instability flows. One hypothesis is that the bubbles contain coronal temperature plasma and rise into the prominence above due to both magnetic and thermal buoyancy, eventually breaking down via a magnetic Rayleigh-Taylor (RT) instability to release hot plasma and magnetic flux and helicity into the overlying coronal flux rope. Another posits that the bubbles are actually just “arcades” in the prominence indicating a magnetic separator line between the bipole and the prominence fields with the observed upflows and downflows caused by reconnection along the separator. We analyze Hinode/SOT, SDO/AIA, and IRIS observations of prominence bubbles, focusing on characteristics of the bubble boundary layers that may discriminate between the two hypotheses. We find speeds on the order of 10 km/s in prominence plasma downflows and lateral shear flows along the bubble boundary. Inflows to the boundary gradually increase the thickness and brightness of the layer until plasma drains from there, apparently around the dome-like bubble domain. In one case, shear flow across the bubble boundary develops Kelvin-Helmholtz (KH) vortices that we use to infer flow speeds in the low-density bubble on the order of 100 km/sec. IRIS spectra indicate that plasma flows on the bubble boundary at transition region temperatures achieve Doppler speeds on the order of 50 km/s, consistent with this inference. Combined magnetic KH-RT instability analysis leads to flux density estimates of 10 G with a field angle of 30° to the prominence, consistent with vector magnetic field measurements. In contrast, we find no evidence

Relationship between social interaction bids and language in late talking children.

Science.gov (United States)

Vuksanovic, Jasmina R

2015-03-28

The aim of this paper is to explore the relationship between language development and the frequency of social interaction (SI) behaviours during language acquisition in late-talking (LT) children who exhibit delays in expressive vocabulary development but have age-appropriate cognitive skills. The research consists of a longitudinal study with a first test followed by two re-tests 5 months apart, in which LT children were compared to 5-months-younger typically-developing (TD) children. Data showed that LT children performed significantly fewer initiation of SI behaviours, but no differences between groups in responding to SI behaviours were observed. Furthermore, LT children who have lower language comprehension scores initiate social interaction more frequently. The results showed that LT children seem to be less active in starting social interaction and participation, but, once they get involved, they respond similarly to TD children of comparable expressive language competence. Additionally, the correlation pattern between the frequency of SI behaviours and language functions showed that LT toddlers with more prominent receptive language delay are more interested in initiating interaction with their partner, thus suggesting that they need a partner's "scaffolding" to overcome this lack.

Future talk in later life.

Paoletti, Isabella; Gomes, Sandra

2014-04-01

This article focuses on the relevance that the dimension of the future has for promoting healthy and active aging. Older people generally have difficulties in talking about the future and when they do they generally express very negative perspectives on it. The data analyzed in this paper are part of an on-going interdisciplinary research project: "Aging, poverty and social exclusion: an interdisciplinary study on innovative support services" (https://apseclunl.wordpress.com/). The project aims at documenting good practices in social intervention with older people who are at risk of exclusion. This study describes and critically discusses an activity carried out in Portugal among older women in a poor area in the suburb of Lisbon entitled "self-awareness workshop on the future". Through a detailed discourse analysis within an ethnomethodological framework the study shows age membership categorizations in use and categorization processes, examining the workshop interaction. In particular, the article describes how the psychologist works at deconstructing and problematizing the negative connotations related to age membership categories. Taking into consideration the interactionally constructed nature of aging and the material consequences that different attitudes towards aging can imply is very important in particular in relation to the provision of services to older people.

"We will not rest." Filipino women want a fertility management program that respects women's dignity, women's bodies and women's choices.

Science.gov (United States)

Alvarez, R O

1993-03-01

The program officer for the Institute for Social Studies and Action presents 1) her views on women's fertility management under different political administrations in the Philippines, 2) the political postures of influential groups, 3) the goals of women's and health groups, and 4) the actions taken by Filipino women. Under Ferdinand Marcos, the official family planning (FP) program emphasized reduction of population growth and established a quota system and incentives for the number of new acceptors. Women, as a result, became victims; e.g. IUDs were inserted without prior knowledge, and inadequate information and follow-up were provided on oral contraceptive use. Efforts were criticized for treating women as program targets and not as individuals capable of making choices. Under Corazon Aquino, the Roman Catholic hierarchy dominated and would have banned all forms of artificial contraception had women's and health groups not blocked the effort. Only in 1989 did President Aquino finally announce that multiple methods of family planning (FP) would be promoted. There was a transition in program services during the transfer to the Department of Health. Currently the government promotes FP within the safe motherhood and child survival context, but adolescents and unmarried women and couples are excluded from FP services. Population control advocates believe FP is a health issue. The Roman Catholic Church accepts only natural methods and believes artificial methods interfere with the natural processes of procreation. Anti-FP groups promote only natural FP methods and wage campaigns to discredit contraceptive methods. Women's and FP groups contend that it is a woman's right to regulate her own fertility. Safe abortion should be made available to those who need it. Women's networks are mobilizing to talk about the issues, to hold public activities to change laws and policies and to encourage women's involvement in decision making affecting their lives, and to conduct

EUV lines observed with EIS/Hinode in a solar prominence

Science.gov (United States)

Labrosse, N.; Schmieder, B.; Heinzel, P.; Watanabe, T.

2011-07-01

Context. During a multi-wavelength observation campaign with Hinode and ground-based instruments, a solar prominence was observed for three consecutive days as it crossed the western limb of the Sun in April 2007. Aims: We report on observations obtained on 26 April 2007 using EIS (Extreme ultraviolet Imaging Spectrometer) on Hinode. They are analysed to provide a qualitative diagnostic of the plasma in different parts of the prominence. Methods: After correcting for instrumental effects, the rasters at different wavelengths are presented. Several regions within the same prominence are identified for further analysis. Selected profiles for lines with formation temperatures between log (T) = 4.7 and log (T) = 6.3, as well as their integrated intensities, are given. The profiles of coronal, transition region, and He ii lines are discussed. We pay special attention to the He ii line, which is blended with coronal lines. Results: Some quantitative results are obtained by analysing the line profiles. They confirm that depression in EUV lines can be interpreted in terms of two mechanisms: absorption of coronal radiation by the hydrogen and neutral helium resonance continua, and emissivity blocking. We present estimates of the He ii line integrated intensity in different parts of the prominence according to different scenarios for the relative contribution of absorption and emissivity blocking to the coronal lines blended with the He ii line. We estimate the contribution of the He ii 256.32 Å line to the He ii raster image to vary between ~44% and 70% of the raster's total intensity in the prominence according to the different models used to take into account the blending coronal lines. The inferred integrated intensities of the He ii 256 Å line are consistent with the theoretical intensities obtained with previous 1D non-LTE radiative transfer calculations, yielding a preliminary estimate of the central temperature of 8700 K, a central pressure of 0.33 dyn cm-2, and a

Many solar prominences end their lives in eruptions or abrupt disappearances that are associated with dynamical or thermal instabilities. Such instabilities are important because they may be responsible for energy transport and conversion. We present a clear observation of a streaming kink-mode Kelvin–Helmholtz Instability (KHI) taking place in a solar prominence using the Hα Lyot filter installed at the New Vacuum Solar Telescope, Fuxian-lake Solar Observatory in Yunnan, China. On one side of the prominence, a series of plasma blobs floated up from the chromosphere and streamed parallel to the limb. The plasma stream was accelerated to about 20–60 km s‑1 and then undulated. We found that 2″- and 5″-size vortices formed, floated along the stream, and then broke up. After the 5″-size vortex, a plasma ejection out of the stream was detected in the Solar Dynamics Observatory/Atmospheric Imaging Assembly images. Just before the formation of the 5″-size vortex, the stream displayed an oscillatory transverse motion with a period of 255 s with the amplitude growing at the rate of 0.001 s‑1. We attribute this oscillation of the stream and the subsequent formation of the vortex to the KHI triggered by velocity shear between the stream, guided by the magnetic field and the surrounding media. The plasma ejection suggests the transport of prominence material into the upper layer by the KHI in its nonlinear stage.

Educational pathways of Black women physicists: Stories of experiencing and overcoming obstacles in life

Science.gov (United States)

Rosa, Katemari

2017-01-01

This talk presents an empirical study on the underrepresentation of people of color in scientific careers. Grounded in Critical Race Theory, the presentation examines the lived experiences of six Black women physicists in the United States, addresses obstacles faced in their career paths, and strategies used to overcome these obstacles. Data for this study were collected through semi-structured interviews and coded for emergent themes, which are invitation to engage in science, communities of science practices, and isolation in the academy. The findings reveal that college recruitment and funding were fundamental for these women to choose Physics over other STEM fields. The analysis shows Physics can be a hostile environment for these women. In addition, Black women experience unique challenges of socialization in Physics, particularly by exclusion of study groups. In this talk, suggestions will be presented to make Physics departments a more inclusive space to support Black women in science. This presentation is based on work supported by the Brazilian government through CAPES (BEX1907-07-7), the Fulbright Program, Comissño Fulbright Brasil, and the Office of Diversity at Teachers College, Columbia University.

To describe the experience of menopausal symptoms of midlife Black women in the United States. Qualitative online forum using a feminist perspective. Internet communities for midlife women and Blacks. Twenty midlife Black women recruited using a quota sampling method. A 6-month online forum was conducted with seven discussion topics on menopausal symptoms. The discussion topics were posted sequentially on the forum site, and the women posted messages at their convenience over 6 months. The data were analyzed using thematic analysis. The identified themes were raised to be strong, accepting a natural aging process, silent and without knowledge, and our own experience. The women tried to be strong during their menopausal transitions while dealing with other important family matters. The women did not report their menopausal symptoms and were silent about or downplayed their symptoms, but many emphasized the importance of education about menopausal symptoms and highlighted their own lack of knowledge. These women generally did not talk about their symptoms because they believed that nobody except other Black midlife women could understand their menopausal experience. Health care providers need to develop a mechanism to deliver the necessary knowledge about menopausal symptoms and management strategies to Black midlife women in their health care practices.

In India, a 2003 law ("COPTA") banned tobacco advertising with the exception of "point of sale" and "on-pack" advertising. Given substantial evidence regarding the impact of point of sale advertising (PoS), we analyzed the prevalence of encountering such advertising in Mumbai, India. A survey was conducted of 199 current and recent former tobacco users recruited at the Tata Memorial Hospital (Mumbai). Enrollees were queried regarding their exposure to tobacco advertising in the last 30 days through multiple media sources. Descriptive epidemiologic techniques were used to characterize the data. Overall, 95% of participants were men and 5% were women (mean age=49 years). All were current tobacco users or quit using all forms of tobacco in the last 60 days. Participants' responses revealed that PoS tobacco advertising had been encountered in the last 30 days for cigarettes (61%), bidis (54%), and smokeless tobacco (59%). Other forms of tobacco advertising were virtually non-existent. PoS tobacco advertising remains prominent and highly visible to consumers in Mumbai, India, indicating corporate exploitation of a loophole in the COPTA legislation. Given the observed compliance with the currently imposed bans, revisions of COPTA to include all forms of tobacco promotion and advertising would be impactful.

Prominence and tornado dynamics observed with IRIS and THEMIS

Science.gov (United States)

Schmieder, Brigitte; Levens, Peter; Labrosse, Nicolas; Mein, Pierre; Lopez Ariste, Arturo; Zapior, Maciek

2017-08-01

Several prominences were observed during campaigns in September 2013 and July 2014 with the IRIS spectrometer and the vector magnetograph THEMIS (Tenerife). SDO/AIA and IRIS provided images and spectra of prominences and tornadoes corresponding to different physical conditions of the transition region between the cool plasma and the corona. The vector magnetic field was derived from THEMIS observations by using the He D3 depolarisation due to the magnetic field. The inversion code (PCA) takes into account the Hanle and Zeeman effects and allows us to compute the strength and the inclination of the magnetic field which is shown to be mostly horizontal in prominences as well as in tornadoes. Movies from SDO/AIA in 304 A and Hinode/SOT in Ca II show the highly dynamic nature of the fine structures. From spectra in Mg II and Si IV lines provided by IRIS and H-alpha observed by the Multi-channel Subtractive Double Pass (MSDP) spectrograph in the Meudon Solar Tower we derived the Doppler shifts of the fine structures and reconstructed the 3D structure of tornadoes. We conclude that the apparent rotation of AIA tornadoes is due to large-scale quasi-periodic oscillations of the plasma along more or less horizontal magnetic structures.

New trends in knowledge dissemination: TED Talks

2014-05-01

Full Text Available This paper investigates the key elements of ethos, pathos and logos linguistic strategies as some main features of TED (Technology, Entertainment, Design Talks, popularizing speeches aiming at Knowledge Dissemination. Through a comparison between the TED Talk ‘HIV - How to fight an epidemic of bad laws’, by Shereen El-Feki (2012a, and another speech held by the same author at the  2012 Symposia The Global Commission on HIV and the Law, addressed to specialists, the paper analyses TED Talks as an innovative tool of popularization, which breaches the typical triangularisation ‘scientist-mediator-audience’, bringing scientists directly into contact with their audiences. Drawing upon Aristotle’s three pillars of rhetoric, the paper analyses the strategies used to establish the ethos of the speech, by proposing a topic as morally worth of spreading; pathos, by creating a direct contact with the public; and logos, investigated through an analysis of the elements used to recontextualise scientific discourses into popularized speeches. The analysis suggests that TED Talks are a recodification, not a mere translation of texts; they are a means to disseminate knowledge reducing the asymmetry between audiences and scientists.

We report an unusual set of observations of waves in a large prominence pillar that consist of pulses propagating perpendicular to the prominence magnetic field. We observe a huge quiescent prominence with the Solar Dynamics Observatory Atmospheric Imaging Assembly in EUV on 2012 October 10 and only a part of it, the pillar, which is a foot or barb of the prominence, with the Hinode Solar Optical Telescope (SOT; in Ca II and Hα lines), Sac Peak (in Hα, Hβ, and Na-D lines), and THEMIS ({sup T}élescope Héliographique pour l' Etude du Magnétisme et des Instabilités Solaires{sup )} with the MTR (MulTi-Raies) spectropolarimeter (in He D{sub 3} line). The THEMIS/MTR data indicates that the magnetic field in the pillar is essentially horizontal and the observations in the optical domain show a large number of horizontally aligned features on a much smaller scale than the pillar as a whole. The data are consistent with a model of cool prominence plasma trapped in the dips of horizontal field lines. The SOT and Sac Peak data over the four hour observing period show vertical oscillations appearing as wave pulses. These pulses, which include a Doppler signature, move vertically, perpendicular to the field direction, along thin quasi-vertical columns in the much broader pillar. The pulses have a velocity of propagation of about 10 km s{sup –1}, a period of about 300 s, and a wavelength around 2000 km. We interpret these waves in terms of fast magnetosonic waves and discuss possible wave drivers.

A twisted flux-tube model for solar prominences. I. General properties

International Nuclear Information System (INIS)

Priest, E.R.; Hood, A.W.; Anzer, U.

1989-01-01

It is proposed that a solar prominence consists of cool plasma supported in a large-scale curved and twisted magnetic flux tube. As long as the flux tube is untwisted, its curvature is concave toward the solar surface, and so it cannot support dense plasma against gravity. However, when it is twisted sufficiently, individual field lines may acquire a convex curvature near their summits and so provide support. Cool plasma then naturally tends to accumulate in such field line dips either by injection from below or by thermal condensation. As the tube is twisted up further or reconnection takes place below the prominence, one finds a transition from normal to inverse polarity. When the flux tube becomes too long or is twisted too much, it loses stability and its true magnetic geometry as an erupting prominence is revealed more clearly. 56 refs

Exploring men's and women's experiences of depression and engagement with health professionals: more similarities than differences? A qualitative interview study

Directory of Open Access Journals (Sweden)

Ziebland Sue

2007-07-01

Full Text Available Abstract Background It is argued that the ways in which women express emotional distress mean that they are more likely to be diagnosed with depression, while men's relative lack of articulacy means their depression is hidden. This may have consequences for communicating with health professionals. The purpose of this analysis was to explore how men and women with depression articulate their emotional distress, and examine whether there are gender differences or similarities in the strategies that respondents found useful when engaging with health professionals. Methods In-depth qualitative interviews with 22 women and 16 men in the UK who identified themselves as having had depression, recruited through general practitioners, psychiatrists and support groups. Results We found gender similarities and gender differences in our sample. Both men and women found it difficult to recognise and articulate mental health problems and this had consequences for their ability to communicate with health professionals. Key gender differences noted were that men tended to value skills which helped them to talk while women valued listening skills in health professionals, and that men emphasised the importance of getting practical results from talking therapies in their narratives, as opposed to other forms of therapy which they conceptualised as 'just talking'. We also found diversity among women and among men; some respondents valued a close personal relationship with health professionals, while others felt that this personal relationship was a barrier to communication and preferred 'talking to a stranger'. Conclusion Our findings suggest that there is not a straightforward relationship between gender and engagement with health professionals for people with depression. Health professionals need to be sensitive to patients who have difficulties in expressing emotional distress and critical of gender stereotypes which suggest that women invariably find it easy to

The physical connections among and formation mechanisms of various components of the prominence-horn cavity system remain elusive. Here we present observations of such a system, focusing on a section of the prominence that rises and separates gradually from the main body. This forms a configuration sufficiently simple to yield clues regarding the above issues. It is characterized by embedding horns, oscillations, and a gradual disappearance of the separated material. The prominence-horn structure exhibits a large-amplitude longitudinal oscillation with a period of ∼150 minutes and an amplitude of ∼30 Mm along the trajectory defined by the concave horn structure. The horns also experience a simultaneous transverse oscillation with a much smaller amplitude (∼3 Mm) and a shorter period (∼10–15 minutes), likely representative of a global mode of the large-scale magnetic structure. The gradual disappearance of the structure indicates that the horn, an observational manifestation of the field-aligned transition region separating the cool and dense prominence from the hot and tenuous corona, is formed due to the heating and diluting process of the central prominence mass; most previous studies suggested that it is the opposite process, i.e., the cooling and condensation of coronal plasmas, that formed the horn. This study also demonstrates how the prominence transports magnetic flux to the upper corona, a process essential for the gradual build-up of pre-eruption magnetic energy.

Mental State Talk Structure in Children’s Narratives: A Cluster Analysis

Directory of Open Access Journals (Sweden)

Giuliana Pinto

2017-01-01

Full Text Available This study analysed children’s Theory of Mind (ToM as assessed by mental state talk in oral narratives. We hypothesized that the children’s mental state talk in narratives has an underlying structure, with specific terms organized in clusters. Ninety-eight children attending the last year of kindergarten were asked to tell a story twice, at the beginning and at the end of the school year. Mental state talk was analysed by identifying terms and expressions referring to perceptual, physiological, emotional, willingness, cognitive, moral, and sociorelational states. The cluster analysis showed that children’s mental state talk is organized in two main clusters: perceptual states and affective states. Results from the study confirm the feasibility of narratives as an outlet to inquire mental state talk and offer a more fine-grained analysis of mental state talk structure.

Observations in the 171 A channel of the Atmospheric Imaging Assembly of the space-borne Solar Dynamics Observatory show tornado-like features in the atmosphere of the Sun. These giant tornadoes appear as dark, elongated, and apparently rotating structures in front of a brighter background. This phenomenon is thought to be produced by rotating magnetic field structures that extend throughout the atmosphere. We characterize giant tornadoes through a statistical analysis of properties such as spatial distribution, lifetimes, and sizes. A total number of 201 giant tornadoes are detected in a period of 25 days, suggesting that, on average, about 30 events are present across the whole Sun at a time close to solar maximum. Most tornadoes appear in groups and seem to form the legs of prominences, thus serving as plasma sources/sinks. Additional H{alpha} observations with the Swedish 1 m Solar Telescope imply that giant tornadoes rotate as a structure, although they clearly exhibit a thread-like structure. We observe tornado groups that grow prior to the eruption of the connected prominence. The rotation of the tornadoes may progressively twist the magnetic structure of the prominence until it becomes unstable and erupts. Finally, we investigate the potential relation of giant tornadoes to other phenomena, which may also be produced by rotating magnetic field structures. A comparison to cyclones, magnetic tornadoes, and spicules implies that such events are more abundant and short-lived the smaller they are. This comparison might help to construct a power law for the effective atmospheric heating contribution as a function of spatial scale.

Morphology Of A Hot Prominence Cavity Observed with Hinode/XRT and SDO/AIA

Science.gov (United States)

Weber, Mark A.; Reeves, K. K.; Gibson, S. E.; Kucera, T. A.

2012-01-01

Prominence cavities appear as circularly shaped voids in coronal emission over polarity inversion lines where a prominence channel is straddling the solar limb. The presence of chromospheric material suspended at coronal altitudes is a common but not necessary feature within these cavities. These voids are observed to change shape as a prominence feature rotates around the limb. We use a morphological model projected in cross-sections to fit the cavity emission in Hinode/XRT passbands, and then apply temperature diagnostics to XRT and SDO/AIA data to investigate the thermal structure. We find significant evidence that the prominence cavity is hotter than the corona immediately outside the cavity boundary. This investigation follows upon "Thermal Properties of A Solar Coronal Cavity Observed with the X-ray Telescope on Hinode" by Reeves et al., 2012, ApJ, in press.

Indian politics encourages durgas, snubs women.

Science.gov (United States)

Kishwar, M

1999-01-01

This article talks about four Indian women--Sonia Gandhi, Jayalitha, Mayawati, and Mamta Banerjee--in contrast with India's stereotypes in the political realm. India is a land of mind-boggling diversity. Yet stereotypes about India, which reduce the Indian reality to a unidimensional monolith, hold powerful sway. One such powerful stereotype is that Indian women are brutally oppressed, denied a voice in their family and community, and marginalized in politics as in other power structures. Without doubt, there is much truth in this stereotype; but how can the current political scene be explained? A few women are holding the entire political establishment of India at ransom. The machinations of Sonia Gandhi, Jayalalitha, Mayawati, and Mamta Banerjee have caused enormous upheavals in the polity and recently brought about the fall of the BJP government. Powerful politicians dance to the erratic tunes of these women and are shamefully submissive to them.

It is first suggested that two social mechanisms leading to self-awareness could be reproduced by self-talk: engaging in dialogues with ourselves, in which we talk to fictive persons, would permit an internalization of others' perspectives; and addressing comments to ourselves about ourselves, as others do toward us, would allow an acquisition of self-in...

HELICAL MOTIONS OF FINE-STRUCTURE PROMINENCE THREADS OBSERVED BY HINODE AND IRIS

Fine-structure dynamics in solar prominences holds critical clues to understanding their physical nature of significant space-weather implications. We report evidence of rotational motions of horizontal helical threads in two active-region prominences observed by the Hinode and/or Interface Region Imaging Spectrograph satellites at high resolution. In the first event, we found transverse motions of brightening threads at speeds up to 55 km s{sup -1} seen in the plane of the sky. Such motions appeared as sinusoidal space–time trajectories with a typical period of ∼390 s, which is consistent with plane-of-sky projections of rotational motions. Phase delays at different locations suggest the propagation of twists along the threads at phase speeds of 90–270 km s{sup -1}. At least 15 episodes of such motions occurred in two days, none associated with an eruption. For these episodes, the plane-of-sky speed is linearly correlated with the vertical travel distance, suggestive of a constant angular speed. In the second event, we found Doppler velocities of 30–40 km s{sup -1} in opposite directions in the top and bottom portions of the prominence, comparable to the plane-of-sky speed. The moving threads have about twice broader line widths than stationary threads. These observations, when taken together, provide strong evidence for rotations of helical prominence threads, which were likely driven by unwinding twists triggered by magnetic reconnection between twisted prominence magnetic fields and ambient coronal fields.

Pathway cross-talk network analysis identifies critical pathways in neonatal sepsis.

Meng, Yu-Xiu; Liu, Quan-Hong; Chen, Deng-Hong; Meng, Ying

2017-06-01

Despite advances in neonatal care, sepsis remains a major cause of morbidity and mortality in neonates worldwide. Pathway cross-talk analysis might contribute to the inference of the driving forces in bacterial sepsis and facilitate a better understanding of underlying pathogenesis of neonatal sepsis. This study aimed to explore the critical pathways associated with the progression of neonatal sepsis by the pathway cross-talk analysis. By integrating neonatal transcriptome data with known pathway data and protein-protein interaction data, we systematically uncovered the disease pathway cross-talks and constructed a disease pathway cross-talk network for neonatal sepsis. Then, attract method was employed to explore the dysregulated pathways associated with neonatal sepsis. To determine the critical pathways in neonatal sepsis, rank product (RP) algorithm, centrality analysis and impact factor (IF) were introduced sequentially, which synthetically considered the differential expression of genes and pathways, pathways cross-talks and pathway parameters in the network. The dysregulated pathways with the highest IF values as well as RPpathways in neonatal sepsis. By integrating three kinds of data, only 6919 common genes were included to perform the pathway cross-talk analysis. By statistic analysis, a total of 1249 significant pathway cross-talks were selected to construct the pathway cross-talk network. Moreover, 47 dys-regulated pathways were identified via attract method, 20 pathways were identified under RPpathways with the highest IF were also screened from the pathway cross-talk network. Among them, we selected 8 common pathways, i.e. critical pathways. In this study, we systematically tracked 8 critical pathways involved in neonatal sepsis by integrating attract method and pathway cross-talk network. These pathways might be responsible for the host response in infection, and of great value for advancing diagnosis and therapy of neonatal sepsis. Copyright © 2017

Liking goes with liking: An intuitive congruence between preference and prominence.

Science.gov (United States)

Morvinski, Coby; Amir, On

2018-03-26

In a series of 8 experiments, we demonstrate the existence of a "labeling effect" wherein people intuitively relate preferred choices to prominently labeled cues (such as heads as opposed to tails in a coin toss) and vice versa. Importantly, the observed congruence is asymmetric-it does not manifest for nonprominent cues and nonpreferred choices. This is because the congruence is driven by a process of evaluative matching: prominent cues are liked, but nonprominent cues are neutral or at most slightly negative in contrast. When we test prominent, yet truly negatively labeled cues, we indeed find a matching with less liked products. We discuss the theoretical contributions to the study of preferences and decision making, as well as demonstrate the practical implications to researchers and practitioners by using this process to assess intuitive preferences and reduce the compromise effect.

Full Text Available Recent years have seen an increase in visible and sometimes even prominent roles for women in terrorist organisations. Both academics and organisations involved in counter-terrorism have paid increasing attention to he role of women not only as supporters of, but also as opponents to political violence. This Policy Brief examines the position of women in Afghanistan vis-à-vis the Taliban. Research Fellow Seran de Leede explores if Afghan women have been involved in the armed struggle of the Taliban as either active or passive supporters. She also considers the resilience women have shown towards political violence in Afghanistan and the possible role women can play in countering violent extremism in the country. Ultimately, this Policy Brief aims to contribute to a better understanding of the role of women in (countering political violence in Afghanistan.

The Fifth DOE Review of Laboratory Programs for Women was held at Brookhaven National Laboratory, May 6--8, 1996, and was co-sponsored by Princeton Plasma Physics Laboratory. The 1996 Review was organized as a Professional Workshop, that is, there were Invited Talks, plus Oral and Poster Presentations from the participants. These sessions were organized around the Focus Topics selected for the Review. The Focus Topics were: school-lab programs, college programs, positive image of women, cultural audits, employee development, employee mentoring, networking, dependent care, and alternate work schedules. On Monday evening, Toni Joseph gave an informal talk to the participants. She stressed the importance of submitting the Action Items for the respective facilities, and assured them that they would be looked at by the Office of Energy Research. On Tuesday morning, the DOE Points-of-Contact (POC) presented an overview of the past Reviews to give some background on the present DOE Review, and discussed plans for the future. The Review concluded with Focus Sessions, one for each Focus Topic. Each of these sessions was charged with producing a report on the session topic. The Focus Group Reports are included in the Proceedings, along with abstracts to the invited talks, oral presentations and poster presentations.

Negotiating constructions of success and failure: women in mid-life and formations of subject, subjectivity and identity

OpenAIRE

McAvoy, Jean

2009-01-01

This thesis explores constructions of success and failure for women in mid-life in Britain in the early 21st century. It takes a discursive approach to social psychology, understanding language as social action constituting subjects and subjectivity. Data from 20 interviews, including 4 conducted with women in pairs, supported by loosely structured questionnaires and a collection of photographs of women including celebrities and unknown women, were used to generate talk of selves and others. ...

Multiuser Communication Through Power Talk in DC MicroGrids

DEFF Research Database (Denmark)

Angjelichinoski, Marko; Stefanovic, Cedomir; Popovski, Petar

2016-01-01

Power talk is a novel ultra narrow-band powerline communication (UNB-PLC) technique for communication among control units in MicroGrids (MGs). Unlike the existing UNB-PLC solutions, power talk does not require installation of additional dedicated communication hardware and, instead, uses only...... transmits at a time, and full duplex, where all units transmit and receive simultaneously. We apply the concepts of signaling space, where the power talk symbol constellations are constructed, and detection space, where the demodulation of the symbols is performed. The proposed communication technique...

Discourse of women on Unesa’s magazine

Science.gov (United States)

Jatiningsih, O.; Habibah, S. M.

2018-01-01

This research aims to reveal the discourse of women in Unesa as mentioned in Unesa’s magazine that is Media of Information and Communication. The data are collected by using documentation technique. The objects of the study are archives, some articles of women published in the Unesa’s magazine. Since 2009, there are three editions of the magazines talked about women. The research used discourse analyses of Foucault. The results reveal that women have been holding large chance to work and having their success, but they must commit themselves to do their role as a wife and a mother. The dominant savoir is domestication of career women. Moreover, the savoir are (1) Women as the first and principal educators of their children; (2) the sacrifice of a wife is an expression of her devotion to her husband. The women’s main sphere is domestics and public is only as an additional sphere. This reflects that patriarchy gender ideology as dominant discourse placing women on their traditional role has been strongly running.

British-Pakistani women's perspectives of diabetes self-management: the role of identity.

Science.gov (United States)

Majeed-Ariss, Rabiya; Jackson, Cath; Knapp, Peter; Cheater, Francine M

2015-09-01

To explore the effects of type 2 diabetes on British-Pakistani women's identity and its relationship with self-management. Type 2 diabetes is more prevalent and has worse outcomes among some ethnic minority groups. This may be due to poorer self-management and an inadequate match of health services to patient needs. The influence that type 2 diabetes has on British-Pakistani women's identity and subsequent self-management has received limited attention. An explorative qualitative study. Face-to-face semi-structured English and Urdu language interviews were conducted with a purposively selected heterogeneous sample of 15 British-Pakistani women with type 2 diabetes. Transcripts were analysed thematically. Four themes emerged: Perceived change in self emphasised how British-Pakistani women underwent a conscious adaptation of identity following diagnosis; Familiarity with ill health reflected women's adjustment to their changed identity over time; Diagnosis improves social support enabled women to accept changes within themselves and Supporting family is a barrier to self-management demonstrated how family roles were an aspect of women's identities that was resilient to change. The over-arching theme Role re-alignment enables successful self-management encapsulated how self-management was a continuous process where achievements needed to be sustained. Inter-generational differences were also noted: first generation women talked about challenges associated with ageing and co-morbidities; second generation women talked about familial and work roles competing with self-management. The complex nature of British-Pakistani women's self-identification requires consideration when planning and delivering healthcare. Culturally competent practice should recognise how generational status influences self-identity and diabetes self-management in ethnically diverse women. Health professionals should remain mindful of effective self-management occurring alongside, and being

Class of analytic solutions for the thermally balanced magnetostatic prominence sheet

International Nuclear Information System (INIS)

Low, B.C.; Wu, S.T.

1981-01-01

This is a theoretical study of the nonlinear interplay between magnetostatic equilibrium and energy balance in a Kippenhahn-Schlueter type prominence sheet. The basic effects are illustrated explicitly with an analytic model in which a radiative loss proportional to rho 2 T balances against wave heating proportional to rho, with thermal conduction confined along magnetic field lines, where rho and T denote the plasma density and temperature, respectively. The particular choices of heat sink and source enable us to integrate the governing equations exactly while they are of the basic mathematical forms to simulate radiative loss in an optically thin plasma which is heated by wave dissipation. The steady solutions exhibit three different basic behaviors, characterized by the total wave heating in the prominence sheet being more than, equal to, or less than the total radiative loss. It is the compaction of the plasma along the field lines under its own weight combined with the effects of energy transport that determines which of the three basic behaviors obtains in a particular situation. The implications of the steady solutions for the formation of prominences are discussed. The exact solutions presented do not support the conclusion of Milne, Priest, and Roberts that there is an upper bound on the plasma beta for an equilibrium of the Kippenhahn-Schlueter prominence

Drawing Women In: Engaging in Science and Engineering Disciplines

Science.gov (United States)

Greene, Senta

2013-03-01

Recent data on the participation of women in the scientific, technological, engineering, and mathematical (STEM) disciplines shows a landscape that is somewhat different from our expectations in the past. For example, women who earn bachelors' degrees in physics go on to earn PhDs, be hired to faculty positions, and achieve promotions at the same rate as their male counterparts. However, such gains do not foretell equal participation of women in physics since, although girls make up about half of high school physics classes, the fraction of bachelor's degrees earned by women has been flat at around 20% for about a decade. This remains true even with significantly increased awareness of the need to attract more women to STEM fields and despite various interventions to attract and retain talented women. This talk will present an overview of data on women's participation in STEM disciplines, provide possible explanations for the continued failure to attract women to some STEM fields, and give a brief description of some current interventions.

Quiescent and Eruptive Prominences at Solar Minimum: A Statistical Study via an Automated Tracking System

Loboda, I. P.; Bogachev, S. A.

2015-07-01

We employ an automated detection algorithm to perform a global study of solar prominence characteristics. We process four months of TESIS observations in the He II 304Å line taken close to the solar minimum of 2008-2009 and mainly focus on quiescent and quiescent-eruptive prominences. We detect a total of 389 individual features ranging from 25×25 to 150×500 Mm2 in size and obtain distributions of many of their spatial characteristics, such as latitudinal position, height, size, and shape. To study their dynamics, we classify prominences as either stable or eruptive and calculate their average centroid velocities, which are found to rarely exceed 3 km/s. In addition, we give rough estimates of mass and gravitational energy for every detected prominence and use these values to estimate the total mass and gravitational energy of all simultaneously existing prominences (1012 - 1014 kg and 1029 - 1031 erg). Finally, we investigate the form of the gravitational energy spectrum of prominences and derive it to be a power-law of index -1.1 ± 0.2.

Associations of parents' self, child, and other "fat talk" with child eating behaviors and weight.

Science.gov (United States)

Lydecker, Janet A; Riley, Kristen E; Grilo, Carlos M

2018-03-15

Fat talk, negative communication about weight, is common in the media, peer groups, and families. Little is known about parental fat talk directed at oneself or others. This study examined associations between different forms of parental fat talk and child disordered eating behaviors and weight, and differences by child sex and age. Parents of preadolescents or adolescents (n = 581) reported fat talk about themselves (self-fat talk), others (obesity-fat talk), and their child (child-fat talk). 76.0% of parents reported regular self-fat talk in front of children, 51.5% reported obesity-fat talk, and 43.6% reported child-fat talk. Fat talk did not differ significantly between parents of preadolescents and adolescents but was more common with sons than daughters. Of the three forms of fat talk, only child-fat talk was associated with all child eating and weight variables (binge eating, overeating, secretive eating, and overweight/obesity); associations were strongest for adolescent girls. Child sex was associated with secretive eating and overweight/obesity. Parents reported using different forms of fat talk frequently. Parent self- and obesity-fat talk were reported more frequently, but child-fat talk was the most strongly associated with children's eating and weight. Because of associations with disordered eating behaviors, intervening to reduce fat talk might contribute to improving pediatric disordered eating and weight-related interventions. © 2018 Wiley Periodicals, Inc.

Heating of an Erupting Prominence Associated with a Solar Coronal Mass Ejection on 2012 January 27

We investigate the heating of an erupting prominence and loops associated with a coronal mass ejection and X-class flare. The prominence is seen as absorption in EUV at the beginning of its eruption. Later, the prominence changes to emission, which indicates heating of the erupting plasma. We find the densities of the erupting prominence using the absorption properties of hydrogen and helium in different passbands. We estimate the temperatures and densities of the erupting prominence and loops seen as emission features using the differential emission measure method, which uses both EUV and X-ray observations from the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory and the X-ray Telescope on board Hinode . We consider synthetic spectra using both photospheric and coronal abundances in these calculations. We verify the methods for the estimation of temperatures and densities for the erupting plasmas. Then, we estimate the thermal, kinetic, radiative loss, thermal conduction, and heating energies of the erupting prominence and loops. We find that the heating of the erupting prominence and loop occurs strongly at early times in the eruption. This event shows a writhing motion of the erupting prominence, which may indicate a hot flux rope heated by thermal energy release during magnetic reconnection.

Observations of apparent superslow wave propagation in solar prominences

Science.gov (United States)

Raes, J. O.; Van Doorsselaere, T.; Baes, M.; Wright, A. N.

2017-06-01

Context. Phase mixing of standing continuum Alfvén waves and/or continuum slow waves in atmospheric magnetic structures such as coronal arcades can create the apparent effect of a wave propagating across the magnetic field. Aims: We observe a prominence with SDO/AIA on 2015 March 15 and find the presence of oscillatory motion. We aim to demonstrate that interpreting this motion as a magneto hydrodynamic (MHD) wave is faulty. We also connect the decrease of the apparent velocity over time with the phase mixing process, which depends on the curvature of the magnetic field lines. Methods: By measuring the displacement of the prominence at different heights to calculate the apparent velocity, we show that the propagation slows down over time, in accordance with the theoretical work of Kaneko et al. We also show that this propagation speed drops below what is to be expected for even slow MHD waves for those circumstances. We use a modified Kippenhahn-Schlüter prominence model to calculate the curvature of the magnetic field and fit our observations accordingly. Results: Measuring three of the apparent waves, we get apparent velocities of 14, 8, and 4 km s-1. Fitting a simple model for the magnetic field configuration, we obtain that the filament is located 103 Mm below the magnetic centre. We also obtain that the scale of the magnetic field strength in the vertical direction plays no role in the concept of apparent superslow waves and that the moment of excitation of the waves happened roughly one oscillation period before the end of the eruption that excited the oscillation. Conclusions: Some of the observed phase velocities are lower than expected for slow modes for the circumstances, showing that they rather fit with the concept of apparent superslow propagation. A fit with our magnetic field model allows for inferring the magnetic geometry of the prominence. The movie attached to Fig. 1 is available at http://www.aanda.org

Gender and age differences in parent-child emotion talk.

Science.gov (United States)

Aznar, Ana; Tenenbaum, Harriet R

2015-03-01

This study examined gender differences in emotion word use during mother-child and father-child conversations. Sixty-five Spanish mothers and fathers and their 4- (M = 53.50, SD = 3.54) and 6-year-old (M = 77.07, SD = 3.94) children participated in this study. Emotion talk was examined during a play-related storytelling task and a reminiscence task (conversation about past experiences). Mothers mentioned a higher proportion of emotion words than did fathers. During the play-related storytelling task, mothers of 4-year-old daughters mentioned a higher proportion of emotion words than did mothers of 4-year-old sons, whereas fathers of 4-year-old daughters directed a higher proportion of emotion words than did fathers of 4-year-old sons during the reminiscence task. No gender differences were found with parents of 6-year-old children. During the reminiscence task daughters mentioned more emotion words with their fathers than with their mothers. Finally, mothers' use of emotion talk was related to whether children used emotion talk in both tasks. Fathers' use of emotion talk was only related to children's emotion talk during the reminiscence task. © 2014 The British Psychological Society.

Love and Family: Discussions Between Swedish Men and Women Concerning the Transition to Parenthood

Directory of Open Access Journals (Sweden)

Disa Bergnéhr

2007-01-01

Full Text Available This study is an exploration of how young Swedish adults talk about intimate relationships and the transition to parenthood. It is suggested that people carefully reflect over their relationship with their partner before deciding to embark on parenthood, and it is shown that reproductive decision making is imbued with contradictory ideals that may cause stress and anxiety. To have and to raise a child in a nuclear family arrangement is one prominent ideal that is illuminated by this study, but parallel with this is the notion of intimate relationships breaking down, dwindling. These two discourses are contradictory and create dilemmas in the process of family formation. Some individuals find the risk of relationship dissolution especially stressful, drawing on their own childhood experiences of growing up with separated parents. This is a study based on focus group interviews containing men and women, ranging from 24 to 39 years old, with different educational, occupational and geographical backgrounds; some are parents and some are not. The data are analysed using a discourse analytical approach, and much of the discussion is based on Anthony GIDDENS', Zygmunt BAUMAN's and Ulrich BECK and Elisabeth BECK-GERNSHEIM's reasoning about love and intimacy in the contemporary Western world.

Regions of rarefied density often form cavities above quiescent prominences. We observed two different cavities with the Coronal Multichannel Polarimeter on 2005 April 21 and with Hinode/EIS on 2008 November 8. Inside both of these cavities, we find coherent velocity structures based on spectral Doppler shifts. These flows have speeds of 5-10 km s -1 , occur over length scales of tens of megameters, and persist for at least 1 hr. Flows in cavities are an example of the nonstatic nature of quiescent structures in the solar atmosphere.

Prominent crista terminalis mimicking a right atrial mass: case report

Directory of Open Access Journals (Sweden)

Lange Peter

2010-10-01

Full Text Available Abstract The crista terminalis is a normal anatomical structure within the right atrium that is not normally visualised in the standard views obtained while performing a transthoracic echocardiogram. In this case report, transthoracic echocardiography suggested the presence of a right atrial mass in a patient with end stage renal disease. However, subsequent transesophageal echocardiography revealed that the right atrial mass was actually a thick muscular bridge in the right atrium consistent with a prominent crista terminalis. An understanding of the anatomy and the echocardiographic appearance of a prominent crista terminalis will minimize the misdiagnosis of this structure avoiding unnecessary expensive additional tests.

ERRATUM: Propagating Waves Transverse to the Magnetic Field in a Solar Prominence

Schmieder, B.; Kucera, T. A.; Knizhnik, K.; Luna, M.; Lopez-Ariste, A.; Toot, D.

2014-01-01

We report an unusual set of observations of waves in a large prominence pillar that consist of pulses propagating perpendicular to the prominence magnetic field. We observe a huge quiescent prominence with the Solar Dynamics Observatory Atmospheric Imaging Assembly in EUV on 2012 October 10 and only a part of it, the pillar, which is a foot or barb of the prominence, with the Hinode Solar Optical Telescope (SOT; in Ca II and Halpha lines), Sac Peak (in Ha, Hß, and Na-D lines), and THEMIS ("Télescope Héliographique pour l' Etude du Magnétisme et des Instabilités Solaires") with the MTR (MulTi-Raies) spectropolarimeter (in He D3 line). The THEMIS/MTR data indicates that the magnetic field in the pillar is essentially horizontal and the observations in the optical domain show a large number of horizontally aligned features on a much smaller scale than the pillar as a whole. The data are consistent with a model of cool prominence plasma trapped in the dips of horizontal field lines. The SOT and Sac Peak data over the four hour observing period show vertical oscillations appearing as wave pulses. These pulses, which include a Doppler signature, move vertically, perpendicular to the field direction, along thin quasi-vertical columns in the much broader pillar. The pulses have a velocity of propagation of about 10 km/s, a period of about 300 s, and a wavelength around 2000 km. We interpret these waves in terms of fast magnetosonic waves and discuss possible wave drivers.

The Fate of Cool Material in the Hot Corona: Solar Prominences and Coronal Rain

Science.gov (United States)

Liu, Wei; Antolin, Patrick; Sun, Xudong; Vial, Jean-Claude; Berger, Thomas

2017-08-01

As an important chain of the chromosphere-corona mass cycle, some of the million-degree hot coronal mass undergoes a radiative cooling instability and condenses into material at chromospheric or transition-region temperatures in two distinct forms - prominences and coronal rain (some of which eventually falls back to the chromosphere). A quiescent prominence usually consists of numerous long-lasting, filamentary downflow threads, while coronal rain consists of transient mass blobs falling at comparably higher speeds along well-defined paths. It remains puzzling why such material of similar temperatures exhibit contrasting morphologies and behaviors. We report recent SDO/AIA and IRIS observations that suggest different magnetic environments being responsible for such distinctions. Specifically, in a hybrid prominence-coronal rain complex structure, we found that the prominence material is formed and resides near magnetic null points that favor the radiative cooling process and provide possibly a high plasma-beta environment suitable for the existence of meandering prominence threads. As the cool material descends, it turns into coronal rain tied onto low-lying coronal loops in a likely low-beta environment. Such structures resemble to certain extent the so-called coronal spiders or cloud prominences, but the observations reported here provide critical new insights. We will discuss the broad physical implications of these observations for fundamental questions, such as coronal heating and beyond (e.g., in astrophysical and/or laboratory plasma environments).

Talking Cure Models: A Framework of Analysis

Directory of Open Access Journals (Sweden)

Christopher Marx

2017-09-01

Full Text Available Psychotherapy is commonly described as a “talking cure,” a treatment method that operates through linguistic action and interaction. The operative specifics of therapeutic language use, however, are insufficiently understood, mainly due to a multitude of disparate approaches that advance different notions of what “talking” means and what “cure” implies in the respective context. Accordingly, a clarification of the basic theoretical structure of “talking cure models,” i.e., models that describe therapeutic processes with a focus on language use, is a desideratum of language-oriented psychotherapy research. Against this background the present paper suggests a theoretical framework of analysis which distinguishes four basic components of “talking cure models”: (1 a foundational theory (which suggests how linguistic activity can affect and transform human experience, (2 an experiential problem state (which defines the problem or pathology of the patient, (3 a curative linguistic activity (which defines linguistic activities that are supposed to effectuate a curative transformation of the experiential problem state, and (4 a change mechanism (which defines the processes and effects involved in such transformations. The purpose of the framework is to establish a terminological foundation that allows for systematically reconstructing basic properties and operative mechanisms of “talking cure models.” To demonstrate the applicability and utility of the framework, five distinct “talking cure models” which spell out the details of curative “talking” processes in terms of (1 catharsis, (2 symbolization, (3 narrative, (4 metaphor, and (5 neurocognitive inhibition are introduced and discussed in terms of the framework components. In summary, we hope that our framework will prove useful for the objective of clarifying the theoretical underpinnings of language-oriented psychotherapy research and help to establish a more

SOLAR LIMB PROMINENCE CATCHER AND TRACKER (SLIPCAT): AN AUTOMATED SYSTEM AND ITS PRELIMINARY STATISTICAL RESULTS

International Nuclear Information System (INIS)

Wang Yuming; Cao Hao; Chen Junhong; Zhang Tengfei; Yu Sijie; Zheng Huinan; Shen Chenglong; Wang, S.; Zhang Jie

2010-01-01

In this paper, we present an automated system, which has the capability to catch and track solar limb prominences based on observations from the extreme-ultraviolet (EUV) 304 A passband. The characteristic parameters and their evolution, including height, position angle, area, length, and brightness, are obtained without manual interventions. By applying the system to the STEREO-B/SECCHI/EUVI 304 A data during 2007 April-2009 October, we obtain a total of 9477 well-tracked prominences and a catalog of these events available online. A detailed analysis of these prominences suggests that the system has a rather good performance. We have obtained several interesting statistical results based on the catalog. Most prominences appear below the latitude of 60 0 and at the height of about 26 Mm above the solar surface. Most of them are quite stable during the period they are tracked. Nevertheless, some prominences have an upward speed of more than 100 km s -1 , and some others show significant downward and/or azimuthal speeds. There are strong correlations among the brightness, area, and height. The expansion of a prominence is probably one major cause of its fading during the rising or erupting process.

Self-talk influences vertical jump performance and kinematics in male rugby union players.

Edwards, Christian; Tod, David; McGuigan, Michael

2008-11-01

We examined the effects of instructional and motivational self-talk on centre of mass displacement and hip kinematics during the vertical jump. Twenty-four male rugby union players (age 21.1 years, s = 3.5; body mass 81.0 kg, s = 8.9; height 1.80 m, s = 0.06) performed three vertical jump tests, with a 2 min rest between jumps. Before each jump, participants engaged in one of three counterbalanced interventions (motivational self-talk, instructional self-talk or no-intervention). Motivational self-talk led to greater centre of mass displacement (0.602 m, s = 0.076; P = 0.012) than the no-intervention control (0.583 m, s = 0.085). Centre of mass displacement did not differ between instructional self-talk and the control condition or between motivational and instructional self-talk. Motivational (100.75 degrees , s = 16.05; P = 0.001) and instructional self-talk (106.14 degrees , s = 17.04; P = 0.001) led to greater hip displacement than the no-intervention control (94.11 degrees , s = 17.14). There was also a significant difference in hip displacement between motivational and instructional self-talk (P = 0.014), although there was no difference between instructional self-talk and the control condition. Motivational (451.69 degrees /s, s = 74.34; P = 0.008) and instructional self-talk (462.01 degrees /s, s = 74.37; P = 0.001) led to greater hip rotation velocity than the no-intervention control (434.37 degrees /s, s = 75.37), although there was no difference between the two self-talk interventions. These results indicate that self-talk may influence performance and technique during the vertical jump in male rugby players.

Hydrogen line formation in the quescent prominences

International Nuclear Information System (INIS)

Tsovookhuu, Ch.

1980-01-01

Equations of transfer and statistical equilibrium for hydronen atom with eight bound levels and continuum are solved simultaneously. A plane-parallel layer located perpendicular to the Sun surface is taken as a geometrical model. Input parameters of the physical model are optical thickness in the center of Hsub(α) line, electron temperature and concentration in the layer center are well as temperature and density gradients. Functions of sources, line profiles, total energies and the Balmer decrements, which are compared with observations and theoretical calculations made by other authors, have been calculated. The comparison shows that the results are quite acceptable and can be used when analyzing the spectrum and determining physical parameters of solar prominences. Dependence of different performances of the line (equivalent width, central intensity, halfwidth, depth of central depression etc.) on values of initial model parameters is investigated. Line halfwidth is more sensitive to the temperatuu value in the layer center, while central intensity - to the value of temperature gradient and a depth of central depression - to electron concentration. Calculated were shares of primary sources responsible for different excitation mechanism depending on total optical thickness as well as mean probabilities of quantum yield out of a medium which can be used during parametric accountancy of radiation diffusion in solar prominences [ru

Exploring Seven- to Eight-Year-Olds' Use of Self-Talk Strategies

Lee, Scott Weng Fai

2011-01-01

Self-talk has been recognised as a tool used by children to regulate their thinking and behaviour. To support children's use of self-regulatory verbal strategies, educators need to understand the context, content and dynamics of children's self-talk. While a significant amount of empirical research had been carried out on self-talk, most was…

SYNTHETIC HYDROGEN SPECTRA OF OSCILLATING PROMINENCE SLABS IMMERSED IN THE SOLAR CORONA

2016-01-01

We study the behavior of H α and H β spectral lines and their spectral indicators in an oscillating solar prominence slab surrounded by the solar corona, using an MHD model combined with a 1D radiative transfer code taken in the line of sight perpendicular to the slab. We calculate the time variation of the Doppler shift, half-width, and maximum intensity of the H α and H β spectral lines for different modes of oscillation. We find a non-sinusoidal time dependence of some spectral parameters with time. Because H α and H β spectral indicators have different behavior for different modes, caused by differing optical depths of formation and different plasma parameter variations in time and along the slab, they may be used for prominence seismology, especially to derive the internal velocity field in prominences.

HIDDEN WAR AGAINST WOMEN

Directory of Open Access Journals (Sweden)

Şehriban Şahin Kaya

2011-01-01

Full Text Available For the last couple of decades, there has been a dramatic regress in the women’seconomic, social and political positions in Turkey.The number of womenparticipating in job market decreased from 34.1 percent in 1990 to 23.5 percent in2009. Almost 85 percent of the working women are still stuck in traditionalfemale jobs. A diminishing representation of womenin politics and increasingviolence against women have been other features ofthis regression. At the sametime period, a transformation of Turkish media camewith the boom of the numberof commercial TV channels, radio stations, magazines and newspapers. Thisnewly transformed media did manage traditional gender roles to infiltrate thethoughts of women, majority of whom stayed out of job market. The images ofwomen created through the advertisements, TV serials, TV talk shows, andmagazines have been more altruistic family orientedtype than women questingfor equal rights. Today, more and more women watchTV programs, supportcosmetic industry, spend lots of money on clothing, and are very interested intheir body, value traditional gender roles and do not ask for equality. Recently,the scholars began to discuss the rise of conservatism in Turkey withoutaddressing the backward shift in women position invarious spheres of life. Allthese problematical issues mentioned above need tobe considered within asociological framework that should be able to showus the current situation ofwomen in Turkey. This presentation attempts to dothis.

Women's Role in the Agricultural Household: Bargaining and Human Capital

This paper reviews the methods and empirical findings from economic analyses of women's contribution to social welfare and the determinants of their human capital. To understand better women's roles in agricultural households, three themes have gained prominence in the economics literature. First is the conceptualization of the unified family as coordinator of production and consumption over the lifecycle. Second is the role of separability of production and consumption decisions in the agric...

[Behaviour concerning smoking among the patients making use of advice in women health centres].

Kowalska, Alina; Szymański, Przemysław; Rzeźnicki, Adam; Stelmach, Włodzimierz

2007-01-01

The level of knowledge in the society about the harmful influence of smoking is increasing systematically. But there are still many people ignoring the warnings and prohibitions concerning smoking. The results of the research show that it is highly worrying that there are people for whom smoking is incredibly dangerous, e.g. children, youth, women, especially pregnant women. The aim of the work was to establish the percentage of smoking women among the patients of the women health centre, with the special focus on pregnant women. There were 120 women encompassed in this study in the health centre in Opoczno and 120 women using a similar health centre in Lodz between the 1st and the 15th March 2007, using a auditoria survey questionnaire. The collected data was worked out statistically. In the group of 240 tested people, 87 admitted to smoking, which is 36.3% of the respondents. Among the 185 women who were not pregnant, but were smoking, there were 75 (40.5%) and in the group of 55 pregnant women, there were 12 who smoked (f=0.22). Over 22% of the smoking women smoked over 10 cigarettes a day. From among 87 of the surveyed, 35.6% claimed they smoked everywhere they wanted. Majority of the respondents that is 52.9% lived with at least one other smoking person. Over 70% of them would like to quit smoking. Almost 48% stated their doctor has never talked with them about the influence of smoking on their health and almost 42% stated that no nurse or midwife has ever talked to them about this subject. Frequency of smoking among the tested people who were using the women health centre was high. Especially worrying was the percentage of the smoking pregnant women--every fifth of them smoked.

To determine the clinical significance of prominent extra-axial CSF space (EACSFS) in infants, as seen on cranial ultrasound. Between March 1996 and November 1997, all infants who had undergone head ultrasound at our institution and were found to have prominent EACSFS were evaluated. The width of the interhemispheric fissure was measured at three locations at the level of the frontal horn, body and atrium of the lateral ventricles. The depth of the CSF space over the convexity was also measured. The average of these measurements was calculated and each patient was assigned to one of three groups: mild, moderate, or marked. Ultrasound findings were evaluated for other associated abnormalities. Clinical neurodevelopment was evaluated by a pediatric neurologist, and ultrasound and neurodevelopmental findings were correlated. Prominent EACSFS was found in 153 patients, and neurodevelopmental evaluation up to a corrected age of 9 months was available in 133. One hundred and eight of 117 infants with normal neurodevelopment had no other associated abnormality(n=81), or abnormality associated only with grade I subependymal hemorrhage or cyst(n=27). Twelve of 16 infants with an abnormal neurodevelopmental outcome had major abnormalities including PVL, grade IV hemorrhage, and marked ventriculomegaly. Prominent EACSFS alone does not appear to be clinically significant. An abnormal neurodevelopmental outcome is associated with major abnormalities seen on ultrasound. Follow-up examination for prominent EACSFS is not indicated unless the associated abnormality requires further evaluations.

Coordinating talk and practical action

DEFF Research Database (Denmark)

Oshima, Sae; Streeck, Jürgen

2015-01-01

This paper investigates how talk and practical action are coordinated during one type of activity involving professional communication: the service-assessment sequence in hair salons. During this activity, a practical inspection of the haircut must be coupled with sequentially produced verbal acts....... Our analysis of four examples reveals that there is no fixed relationship between the organization of talk and practical action. Instead, people manipulate this relationship on a moment-by-moment basis, often coordinating the two into a single, integral package, or relying on one stream of action...... to achieve progress in the other. These findings imply that some multimodal activities that are brought into alignment may have their own, separate and independent procedural logic and sequencing patterns and that these can be brought into play to create or deal with constraints in each other....

Making weapons, talking peace

International Nuclear Information System (INIS)

York, H.F.

1987-01-01

The memoirs of the author traces his life from his first-year graduate studies in physics at the University of Rochester in 1942 to his present position as Director of the University of California's Institute on Global Conflict and Cooperation. The part of his life involved in making weapons extends from 1942 to 1961. During this period, he worked with E.O. Lawrence on the Manhattan Project and served as director of Livermore after it became the Atomic Energy Commission's second nuclear weapons laboratory. He also served on many government advisory boards and commissions dealing with nuclear and other weapons. In 1961, the combination of a heart attack and changes in administration in Washington led York too return to the University of California for the talking peace portion of his life. He has since become a public exponent of arms control and disarmament and the futility of seeking increased security through more and better nuclear weapons. York's explanation of his move from making weapons to talking peace leaves the reader with a puzzle

Personal factors that contribute to or impair women's ability to achieve orgasm.

This work aims to identify factors that contribute and those that impair the ability to experience orgasm during sexual activity. It compared women (n=96) aged 18-61 (M=38.5 years) in a stable relationship that, after a normal arousal phase, do not have an orgasm (OD) with those that do (OA) regarding sociodemographic data, sexual frequency, talking about sex with their physician, talking about sex with their partner, sexual education, masturbation, sexual desire, sexual satisfaction, depression and anxiety. We found differences between the OD and OA groups with regard to level of education (P=0.022), sex education during childhood and/or adolescence (Porgasm problems included the variables 'masturbation', 'high school', 'sexual desire' and 'anxiety'. Orgasm difficulties are influenced by personal factors, such as anxiety and low sexual desire. Increased levels of anxiety also increase orgasmic difficulties. Women who masturbate and/or have completed high school are considerably more likely to reach orgasm during sexual activity.

Solar Prominences Embedded in Flux Ropes: Morphological Features and Dynamics from 3D MHD Simulations

Science.gov (United States)

Terradas, J.; Soler, R.; Luna, M.; Oliver, R.; Ballester, J. L.; Wright, A. N.

2016-04-01

The temporal evolution of a solar prominence inserted in a three-dimensional magnetic flux rope is investigated numerically. Using the model of Titov & Démoulin under the regime of weak twist, the cold and dense prominence counteracts gravity by modifying the initially force-free magnetic configuration. In some cases a quasi-stationary situation is achieved after the relaxation phase, characterized by the excitation of standing vertical oscillations. These oscillations show a strong attenuation with time produced by the mechanism of continuum damping due to the inhomogeneous transition between the prominence and solar corona. The characteristic period of the vertical oscillations does not depend strongly on the twist of the flux rope. Nonlinearity is responsible for triggering the Kelvin-Helmholtz instability associated with the vertical oscillations and that eventually produces horizontal structures. Contrary to other configurations in which the longitudinal axis of the prominence is permeated by a perpendicular magnetic field, like in unsheared arcades, the orientation of the prominence along the flux rope axis prevents the development of Rayleigh-Taylor instabilities and therefore the appearance of vertical structuring along this axis.

Measuring motivation: change talk and counter-change talk in cognitive behavioral therapy for generalized anxiety.

Science.gov (United States)

Lombardi, Diana R; Button, Melissa L; Westra, Henny A

2014-01-01

How clients talk about change early in treatment has been found to be a potent predictor of their subsequent treatment success. Studies examining such client motivational language (arguments for and against change) have typically been conducted in the context of motivational interviewing for addictions. This study examined the capacity of client motivational language to predict treatment outcomes in the context of cognitive behavioral therapy (CBT) for generalized anxiety. Client early in-session statements against change (counter-change talk) were found to be robust predictors of post-treatment worry scores and differentiated treatment responders from nonresponders. Moreover, client motivational language predicted outcomes beyond initial symptom severity and self-report measures of motivation. These results strongly support the relevance of client motivational language outcomes in CBT and provide a foundation for advancing research on motivation for change in a CBT context.

Cross-talk studies between FCC-hh Experimental Interaction Regions

CERN Document Server

AUTHOR|(CDS)2081283; Seryi, Andrei; Appleby, Robert Barrie; Rafique, Haroon; Besana, Maria Ilaria

2017-01-01

Debris from 50 TeV proton-proton collisions at the main interaction point in the FCC-hh may contribute to the background in the subsequent detector. This cross-talk is of possible concern for the FCC-hh due to the high luminosity and energy of the collider. DPMJET-III is used as a collision debris generator in order to assess the muon cross-talk contribution. An analytical calculation of muon range in rock is performed. This is followed by a full Monte Carlo simulation using FLUKA, where the accelerator tunnel has been modelled. The muon cross talk between the adjacent interaction points is assessed and its implications for FCC-hh design are discussed.

Word-level prominence in Persian: An Experimental Study.

Science.gov (United States)

Sadeghi, Vahid

2017-12-01

Previous literature on the phonetics of stress in Persian has reported that fundamental frequency is the only reliable acoustic correlate of stress, and that stressed and unstressed syllables are not differentiated from each other in the absence of accentuation. In this study, the effects of lexical stress on duration, overall intensity and spectral tilt were examined in Persian both in the accented and unaccented conditions. Results showed that syllable duration is consistently affected by stress in Persian in both the accented and unaccented conditions across all vowel types. Unlike duration, the results for overall intensity and spectral tilt were significant only in the accented condition, suggesting that measures of intensity are not a correlate of stress in Persian but they are mainly caused by the presence of a pitch movement. The findings are phonologically interpreted as suggesting that word-level prominence in Persian is typologically similar to 'stress accent' languages, in which multiple phonetic cues are used to signal the prominence contrast in the accented condition, and stressed and unstressed syllables are different from each other even when the word is not pitch-accented.

"Sex is sweet": women from low-income contexts in Uganda talk about sexual desire and pleasure.

Science.gov (United States)

Muhanguzi, Florence Kyoheirwe

2015-11-01

In many patriarchal societies in Africa, heterosexuality is privileged as the single legitimate form of sexual interaction; other sexualities are marginalised because they are perceived as un-African, abnormal, sinful and are repressed. Female sexuality too is subordinated and controlled with it being reduced to women's conventional mothering roles that are conflated with their reproductive capacities. However, there is evidence that women in heterosexual relations have the opportunity to assert themselves and to define pleasurable sex. Drawing on in-depth interviews and focus group discussions with married women in heterosexual unions the article examines the extent to which women from low-income contexts in Uganda express their sexual agency. The findings show that within heterosexual relations, these women are able to express their sexual desires freely and negotiate diverse options for pleasurable sexual experiences. The evidence indicates the need for acknowledging variations within heterosexual experiences and the possibility of positive heterosexual relationships that resist hegemonic masculinity and subordinated femininity.

Gender, self and pleasure: young women's discourse on masturbation in contemporary Shanghai.

Science.gov (United States)

Yuxin, Pei; Ho Sik Ying, Petula

2009-06-01

This study examines views and experiences of young Shanghai women with respect to masturbation. Through in-depth interviews with forty young women in Shanghai aged 22 to 39 from May 2004 to July 2007, the study explores women's understandings of masturbation, their desires and their lives as modern Chinese women. The focus of the analysis is on how women talk about their masturbation experiences and make sense of their experiences in the context of their sexual relationships and lifestyle choices. By analysing women's narratives about masturbation, the paper suggests that women's self-articulation is actually an engagement in self-image construction. The strategies they use to position themselves in relation to different social discourses on masturbation, how they describe and perform the acts and how they articulate their experiences of masturbation are examined to illustrate how young women in Shanghai perform gender and sexual intimacies in a fast changing city.

Tic Tac TOE: Effects of Predictability and Importance on Acoustic Prominence in Language Production

A standard way to realize communication in microgrid control is to use an external communication network, such as modems for wireless or power-line communication, whose implementation may be inefficient in terms of deployment cost, complexity, and system stability. In this chapter we present......, while its reliability and availability draw on the reliability and availability of the microgrid power transmission system....... a communication solution, denoted as power talk, which is solely based on the use of the existing microgrid power equipment (i.e., power electronics and buses). The pivotal idea is to modulate information in the power-related parameters of the microgrid buses by use of the flexibility of power electronic...

The temporal evolution of a solar prominence inserted in a three-dimensional magnetic flux rope is investigated numerically. Using the model of Titov and Démoulin under the regime of weak twist, the cold and dense prominence counteracts gravity by modifying the initially force-free magnetic configuration. In some cases a quasi-stationary situation is achieved after the relaxation phase, characterized by the excitation of standing vertical oscillations. These oscillations show a strong attenuation with time produced by the mechanism of continuum damping due to the inhomogeneous transition between the prominence and solar corona. The characteristic period of the vertical oscillations does not depend strongly on the twist of the flux rope. Nonlinearity is responsible for triggering the Kelvin–Helmholtz instability associated with the vertical oscillations and that eventually produces horizontal structures. Contrary to other configurations in which the longitudinal axis of the prominence is permeated by a perpendicular magnetic field, like in unsheared arcades, the orientation of the prominence along the flux rope axis prevents the development of Rayleigh–Taylor instabilities and therefore the appearance of vertical structuring along this axis.

To assess the health status of Afghan women and attitudes of these women and their male relatives during the period of Taliban rule toward women's rights and community development needs in Afghanistan. In household residences in two regions in Afghanistan (one Taliban controlled and the other not under the Taliban) and a refugee camp and repatriation center in Pakistan, structured interviews were conducted among a random sample of women and men exposed to Taliban policy and women living in a non-Taliban controlled area (724 Afghan women and 553 male relatives). Major depression was far more prevalent among women exposed to Taliban policies (73%-78%) than among women living in a non-Taliban controlled area (28%). Sixty-five percent of women living in a Taliban-controlled area and 73% of women in Pakistan exposed to Taliban policies expressed suicidal ideation at the time of the study, compared with 18% of those in a non-Taliban controlled area. More than 90% of both women and men expressed support for equal work and educational opportunities, free expression, protection of women's rights, participation of women in government, and the inclusion of women's human rights concerns in peace talks. A majority of both women and men believed that guaranteeing civil and political rights (69%) and meeting basic needs (90%) were important for the health and development of their communities. In Afghanistan under the Taliban, policies restricting women's rights were not the product of years of tradition or of social and economic deprivation. Instead, they were man-made policies as easily and swiftly revoked as they were instituted. Depression rates among women in Afghanistan, especially in Taliban-controlled areas, were extraordinarily high. Current efforts to rebuild Afghanistan must address these high rates of depression and other mental health problems to ensure women's full participation in development.

The intrapersonal component of human communication, self-talk, influences what we say and how we respond to another in interpersonal dialogues. A model of communication that incorporates the notion of self-talk, both that of the speaker and that of the listener, is useful in assisting nurses in making more realistic appraisals of communication interactions and addressing problems in communication failures.

Magnetic field re-arrangement after prominence eruption

International Nuclear Information System (INIS)

Kopp, R.A.; Poletto, G.

1986-01-01

It has long been known that magnetic reconnection plays a fundamental role in a variety of solar events. Although mainly invoked in flare problems, large-scale loops interconnecting active regions, evolving coronal hole boundaries, the solar magnetic cycle itself, provide different evidence of phenomena which involve magnetic reconnection. A further example might be given by the magnetic field rearrangement which occurs after the eruption of a prominence. Since most often a prominence reforms after its disappearance and may be observed at about the same position it occupied before erupting, the magnetic field has to undergo a temporary disruption to relax back, via reconnection, to a configuration similar to the previous one. The above sequence of events is best observable in the case of two-ribbon (2-R) flares but most probably is associated with all filament eruptions. Even if the explanation of the magnetic field rearrangement after 2-R flares in terms of reconnection is generally accepted, the lack of a three-dimensional model capable of describing the field reconfiguration, has prevented, up to now, a thorough analysis of its topology as traced by Hα/x-ray loops. The purpose of the present work is to present a numerical technique which enables one to predict and visualize the reconnected configuration, at any time t, and therefore allows one to make a significant comparison of observations and model predictions throughout the whole process. 5 refs., 3 figs

Successful ADVANCE Initiatives for Junior Women Faculty in STEM

Science.gov (United States)

Riskin, Eve

2015-01-01

The NSF ADVANCE program was designed to transform university policies, procedures, and practices so that women faculty could advance in STEM faculty careers, obtain tenure, and ultimately become academic leaders. The results have been impressive. The most recent data from the American Society of Engineering Education (Fall 2013) show that the average percentage of women faculty in U.S. Colleges of Engineering is now 14.5%; it was just 9% when ADVANCE started in 2001.This talk will describe programs to support and promote junior women faculty that have been successful in recruiting and retaining women in STEM. These programs include mentoring, professional development, and work/life balance initiatives. Suggestions will be made for ways to disseminate low-cost successful ADVANCE programs to other institutions so that they can successfully support their own women faculty in STEM. One effort is the University of Washington's LEAD-it-Yourself! online toolkit that will enable other universities to run their own leadership workshops for department chairs and deans.

"We Hardly Ever Talk about It": Emotional Responsive Attunement in Couples after a Child's Death.

Science.gov (United States)

Hooghe, An; Rosenblatt, Paul C; Rober, Peter

2018-03-01

Within Western cultural traditions, the idea that parents should talk about the death of their child with each other is deeply rooted. However, across bereaved parent couples there are wide variations in communication about their grief with each other. In this study, we explored the experiences of bereaved couples related to the process of talking and not talking. We used a thematic coding approach to analyze 20 interviews with 26 bereaved parents (11 interviewed as couples, four as individuals). Four main meanings emerged out of our analysis: not talking because of the inadequacy and pointlessness of words in grief, not talking as a way to regulate emotions in daily life, not talking as an expression of a personal, intimate process, and not talking because the partner has the same loss but a different grief process. In addition, we found that the process of talking and not talking can partly be understood as an emotional responsive process on an intrapersonal and interpersonal level. In this process partners search for a bearable distance from their own grief and their partner's, and attune with their relational context. A better understanding of this process is sought in a dialectical approach, emphasizing the value of both talking and not talking in a tense relationship with each other. Implications for clinical work are described. © 2017 Family Process Institute.

Suprasegmental information affects processing of talking faces at birth.

Science.gov (United States)

Guellai, Bahia; Mersad, Karima; Streri, Arlette

2015-02-01

From birth, newborns show a preference for faces talking a native language compared to silent faces. The present study addresses two questions that remained unanswered by previous research: (a) Does the familiarity with the language play a role in this process and (b) Are all the linguistic and paralinguistic cues necessary in this case? Experiment 1 extended newborns' preference for native speakers to non-native ones. Given that fetuses and newborns are sensitive to the prosodic characteristics of speech, Experiments 2 and 3 presented faces talking native and nonnative languages with the speech stream being low-pass filtered. Results showed that newborns preferred looking at a person who talked to them even when only the prosodic cues were provided for both languages. Nonetheless, a familiarity preference for the previously talking face is observed in the "normal speech" condition (i.e., Experiment 1) and a novelty preference in the "filtered speech" condition (Experiments 2 and 3). This asymmetry reveals that newborns process these two types of stimuli differently and that they may already be sensitive to a mismatch between the articulatory movements of the face and the corresponding speech sounds.

An International Look at Women in Open Source

Directory of Open Access Journals (Sweden)

Cathy Malmrose

2009-05-01

Full Text Available When attending conferences, working with various open source teams, and generally interacting with people in the open source world, we see women as a small representative minority. The disparity leaves us wondering: "How to activate the other 50% of the population?". The question, "How do we include more women?" has been asked many times and answered in many ways. Cathy Malmrose, CEO of ZaReason, a Linux hardware company, stated, "possibly the most immediately effective solution is to showcase women internationally and their contributions. By simply talking about what women are doing all over the world, it creates an atmosphere of acceptance, encouraging more women to try contributing, no matter where they are located or what their situation is. Our goal is to normalize the experience of having women on open source projects". This issue of OSBR is a powerful effort to do just that. This article provides a glance at women in open source internationally. It is by no means comprehensive and is based solely on a random sampling of women who are currently contributing. The goal of this article is to give you a sense of the breadth and depth of women contributing to open source.

Nuclear wastes: lets talk about

International Nuclear Information System (INIS)

1995-01-01

This colloquium is entirely devoted to the problem of nuclear wastes management and to the anxiety of the French public opinion with respect to radioactive wastes in general. Nuclear wastes, generally are perceived as the unique problem of nuclear industry and as a new and unknown problem for which no solutions have been proposed so far. The aim of this colloquium is to demonstrate that such solutions exist and that, probably, they have been more thoroughly examined than in other industrial sectors. The two first talks give the inventory of possible solutions and the policy followed by nuclear operators for the conditioning and packaging of radioactive wastes. The other talks give the point of view of the producers and of the managers of nuclear wastes and the legal aspects of the management and storage of nuclear wastes, in particular the December 30, 1991 law. A particular attention is given to the importance of communication and public information in the successful management of nuclear wastes. (J.S.)

Let's talk about smear tests: social marketing for the National Cervical Screening Programme.

Science.gov (United States)

Bethune, G R; Lewis, H J

2009-09-01

The overall aim of the work was to increase participation by Māori and Pacific women in the National Cervical Screening Programme (NCSP) in New Zealand using a social marketing informed approach. Key objectives for this target group included: increasing awareness, understanding and discussion of cervical cancer and cervical screening; increasing telephone calls to the NCSP's 0800 number; and increasing uptake of cervical screening. A social marketing intervention with mixed qualitative and quantitative evaluation. Focus groups with priority women and key stakeholder interviews were used to identify a set of key messages from which television, radio and print media advertisements were developed. The advertising campaign was one element of a broader programme of activity, which involved changes to service delivery and improvement to access to services, particularly for the target groups. The campaign was evaluated in three ways: quantitative surveys conducted before, during and after the intervention; monitoring the number of calls to the NCSP's 0800 number; and monitoring NCSP monthly coverage statistics. The social marketing intervention achieved measurable behavioural impacts with its primary target audiences, delivering significant increases in screening uptake by Māori (6.8%) and Pacific women (12.7%) after 12 months. In addition, there was a secondary positive impact on other women (not the immediate target audience) whose rate of update also increased (2.7%). Overall, the intervention helped to reduce inequalities and delivered substantial increases in awareness, understanding and discussion of cervical cancer and cervical screening amongst the target groups. The results demonstrate that social marketing can be effective in targeting marginalized or under-represented groups. The intervention has not only changed the way in which women in New Zealand talk about a previously 'taboo' subject, but it has also provided a platform for significant behaviour change

Is There a War on Women in Psychoanalysis? The Disappearance of a Group of Women Leaders.

Science.gov (United States)

Notman, Malkah T

2015-01-01

Some older members of the Boston Psychoanalytic Society remarked that in the 1950s and 1960s there was a group of prominent women analytic leaders at BPSI. They were training analysts, writers, and teachers active in the society and in the community. They were succeeded primarily by men. The question arose Was that an expression of "the war on women"? This paper explores and discusses this question. Although there were some expressions of resentment at being "dominated" by women, the answer appears to be more complex. For various reasons there was not a group of younger women available to move into this role at that time. The reasons for this are described--including the need for a medical degree for psychoanalytic training, the cultural postwar pressures in the United States for women not to work, and the institutional structural problems making it difficult for women candidates, such as ambivalence about pregnancy and the delays in changes in theory to enter the curriculum. This made for discrepancies between theory and the experience of candidates. The earlier group of women were mostly trained in Europe and the implications of this are described. In the years when the leadership was primarily male, decisions subtly reflected this.

There are several women pioneers in prosthodontics, and each deserves recognition and admiration for all she has achieved in helping bridge the gender gap in dentistry. Women have come a long way from being first depicted as a thieving woman assistant in early 1523 to becoming award-winning, Board-certified clinicians, program directors, department chairs, and deans of dental schools. However, current female resident membership in the American College of Prosthodontists is less than 40%. Women in leadership roles are still scarce, and advancement is still needed. This article provides a brief summary of the history of prosthodontics, highlighting prominent women prosthodontists and their stories, while providing inspiration for future prosthodontists, men as well as women. © 2017 by the American College of Prosthodontists.

As posited in multiple health communication theories, it is vital to understand modern health communication preferences among communities in order to develop tailored interventions to reduce Infant Mortality (IM). Literature suggests that health communication inequalities play an important role in infant health knowledge gaps, thus contributing to the disparate IM rates. We sought to understand preferred methods of communication among expectant or mothers of young children of varying sociodemographics. We hypothesized that methods of communication would vary by sociodemographics. A bilingual questionnaire, developed using community based participatory research principles was offered at pre-selected women's health agencies in the Shenandoah Valley of Virginia. Participants chose from a researched list of 22 methods of communication and also designated their "top three choices." Communication methods were compared across sociodemographics using chi-squared statistical tests. A total of 292 participants completed the questionnaire at the various sites. Participants were predominantly White (60%) or Hispanic/Latina (30%), and lived in Frederick county/Winchester city (77%). Of the 22 communication methods, the five most prevalent were: talking with a healthcare provider (91%), family or friends (85-87%), using internet (84%), and handouts/booklets (80%). Communication methods most frequently chosen as a "top three choice" were: internet (46%), talking with healthcare providers (33%), and talking with family (32%). A higher preference for talking with a healthcare provider was noted among higher income individuals (100%) compared to lower income (82%; p-value=0.0062), a higher preference for call-in hotlines among Hispanic (49%) vs. non-Hispanic women (15%; p-valuefast-food restaurants among older women (42%) compared to younger (16%, p-value=0.0361).

Prominent cerebral veins on susceptibility-weighted imaging (SWI) in pulmonary embolism

Energy Technology Data Exchange (ETDEWEB)

Oeztoprak, Bilge [Cumhuriyet University School of Medicine, Department of Radiology, Sivas (Turkey)

2017-07-15

Clinical applications of susceptibility-weighted imaging (SWI) are increasing steadily. The aim of this study is to investigate the appearance of cerebral veins on SWI, which is very sensitive to the deoxyhaemoglobin level in vessels, in pulmonary embolism (PE). The cranial SWI images of 19 patients with PE and 22 controls from September 2013 through March 2016 were retrospectively examined for the presence of prominent cerebral veins. MRI findings were correlated with blood oxygen levels. 12 of 19 patients with PE had hypoxemia and SWI images of 11 of these hypoxemic patients depicted prominent cerebral veins in the form of increased number, diameter, and elongation. The mean PaO{sub 2} and SaO{sub 2} in these patients were 48.5 ± 9.1 mmHg and 75.2 ± 8.0 %, respectively. There was a significant correlation between the presence of prominent veins on SWI and hypoxemia (p < 0.05). Of the 7 patients with normal blood oxygen pressure and saturation, 1 also showed an augmented appearance of cerebral veins on SWI. In the presence of neurological symptoms suggestive of an intracranial pathology in patients with PE, a SWI added to the conventional MRI sequences may predict hypoxemia and exclude other intracranial pathologies.

Optimizing the orchestration of resemiotization with teacher "talk moves": A model of guided-inquiry instruction in middle school science

Science.gov (United States)

Millstone, Rachel Diana

The current conceptualization of science set forth by the National Research Council (2008) is one of science as a social activity, rather than a view of science as a fixed body of knowledge. This requires teachers to consider how communication, processing, and meaning-making contribute to science learning. It also requires teachers to think deeply about what constitutes knowledge and understanding in science, and what types of instruction are most conducive to preparing students to participate meaningfully in the society of tomorrow. Because argumentation is the prominent form of productive talk leading to the building of new scientific knowledge, one indicator of successful inquiry lies in students' abilities to communicate their scientific understandings in scientific argumentation structures. The overarching goal of this study is to identify factors that promote effective inquiry-based instruction in middle school science classrooms, as evidenced in students' abilities to engage in quality argumentation with their peers. Three specific research questions were investigated: (1) What factors do teachers identify in their practice as significant to the teaching and learning of science? (2) What factors do students identify as significant to their learning of science? and (3) What factors affect students' opportunities and abilities to achieve sophisticated levels of argumentation in the classroom? Two teachers and forty students participated in this study. Four principle sources of data were collected over a three-month period of time. These included individual teacher interviews, student focus group interviews, fieldnotes, and approximately 85 hours of classroom videotape. From this sample, four pathways for guided-inquiry instruction are identified. Opportunities for student talk were influenced by a combination of factors located in the domains of "teacher practice," "classroom systems," and "physical structures." Combinations of elements from these three

Perceptions of Social Responsibility of Prominent Animal Welfare Groups.

Science.gov (United States)

Widmar, Nicole J Olynk; Morgan, Carissa J; Croney, Candace C

2018-01-01

Nonhuman animal welfare is an increasingly important component of consumer expectations of corporate social responsibility (CSR). The extent to which prominent animal welfare or protection organizations may influence people's perceptions of food industry CSR may be related to an organization's perceived social responsibility. Data from an online survey of 300 U.S. residents were used to explore relationships between demographics/lifestyle choices and perceptions of prominent animal welfare organizations (using best-worst scaling methodology). Overall, the American Society for the Prevention of Cruelty to Animals was perceived to be the most socially responsible organization analyzed, followed by the Humane Society of the United States and the American Humane Association (AHA). Results suggest that the perceived social responsibility of animal protection organizations in this study was not strongly linked to personally (financially) supporting them, with 2 exceptions: the perceptions of People for the Ethical Treatment of Animals and AHA. Improved understanding of the perception of animal welfare or protection organizations can inform decision making by organizations interested in furthering animal welfare causes.

Talking Points: Women's Information Needs for Informed Decision-Making About Noninvasive Prenatal Testing for Down Syndrome.

Dane, Aimée C; Peterson, Madelyn; Miller, Yvette D

2018-03-17

Adequate knowledge is a vital component of informed decision-making; however, we do not know what information women value when making decisions about noninvasive prenatal testing (NIPT). The current study aimed to identify women's information needs for decision-making about NIPT as a first-tier, non-contingent test with out-of-pocket expense and, in turn, inform best practice by specifying the information that should be prioritized when providing pre-test counseling to women in a time-limited scenario or space-limited decision support tool. We asked women (N = 242) in Australia to indicate the importance of knowing 24 information items when making a decision about NIPT and to choose two information items they would most value. Our findings suggest that women value having complete information when making decisions about NIPT. Information about the accuracy of NIPT and the pros and cons of NIPT compared to other screening and invasive tests were perceived to be most important. The findings of this study can be used to maximize the usefulness of time-limited discussions or space-limited decision support tools, but should not be routinely relied upon as a replacement for provision of full and tailored information when feasible.

Mother-daughter communication and college women's confidence to communicate with family members and doctors about the human papillomavirus and sexual health.

Science.gov (United States)

Romo, Laura F; Cruz, Maria Elena; Neilands, Torsten B

2011-10-01

In this study, we examined whether mother-daughter sexuality communication in midadolescence contributes to young women's self-efficacy to consult with family members about sexual health problems, and to talk with physicians about the human papillomavirus (HPV). Young European American, Latina, and Asian Pacific Islander college women reported on how confident they felt talking to their family members and doctors about HPV and sexual health issues. We gathered retrospective data regarding the nature of mother-daughter communication, including sexuality communication, in midadolescence. Other variables included physician trust, knowledge about HPV, and reports of current sexual activity. More openness in past general communication with their mothers, more perceived comfort in past sexuality communication, and a greater number of reproductive health topics discussed was linked to greater confidence in communicating with family members about sexual health problems. In addition, higher levels of sexual activity, more knowledge about HPV, and the number of reproductive health topics discussed with mothers in midadolescence, were associated with increased confidence talking to doctors about HPV and sexual health. Positive communication experiences with mothers in the early years may reduce the shame, embarrassment, and anxiety associated with talking to physicians about sensitive sexuality issues.

The EU and Climate Change Policy: Law, Politics and Prominence at Different Levels

Directory of Open Access Journals (Sweden)

Chad David Damro

2008-11-01

Full Text Available The European Union (EU is a prominent player in the politics of climate change, operating as an authoritative regional actor that influences policy-making at the national and international levels. The EU’s climate change policies are thus subjected to multiple pressures that arise from the domestic politics of its twenty-seven individual member states and the international politics of non-EU states with which it negotiates. Facing these multiple pressures, how and why could such a non-traditional actor develop into a prominent player at different levels of climate change policy-making? This article argues that the EU’s rise to prominence can be understood by tracking a number of historical-legal institutional developments at the domestic and international levels. The article also provides a preliminary investigation of the EU emissions trading scheme, a new institutional mechanism that illustrates the policy pressures arising from different levels.

Women in rural Romania face significant health disadvantages. This qualitative pilot study describes the structural disadvantage experienced during pregnancy by women in rural Romania, focusing on the lived experiences of Roma women. We explore how women in rural communities experience pregnancy, their interactions with the healthcare system, and the role that ethnic and social factors play in pregnancy and childbearing. We conducted 42 semi-structured interviews with health and other professionals, seven narrative interviews with Roma and non-Roma women and a focus group with Roma women. Data were analysed using thematic analysis. We identified intersectional factors associated with women's pregnancy experiences: women perceiving pregnancy as both unplanned and wanted, joyful, and normal; women's and professionals' differing prenatal care perceptions; transport and cost related barriers to care; socioeconomic and ethnic discrimination; and facilitators to care such as social support, having a health mediator and having a doctor. Talking directly with professionals and Roma and non-Roma women helped us understand these many factors, how they are interconnected, and how we can work towards improving the pregnancy experiences of Roma women in rural Romania.

MolTalk--a programming library for protein structures and structure analysis.

Science.gov (United States)

Diemand, Alexander V; Scheib, Holger

2004-04-19

Two of the mostly unsolved but increasingly urgent problems for modern biologists are a) to quickly and easily analyse protein structures and b) to comprehensively mine the wealth of information, which is distributed along with the 3D co-ordinates by the Protein Data Bank (PDB). Tools which address this issue need to be highly flexible and powerful but at the same time must be freely available and easy to learn. We present MolTalk, an elaborate programming language, which consists of the programming library libmoltalk implemented in Objective-C and the Smalltalk-based interpreter MolTalk. MolTalk combines the advantages of an easy to learn and programmable procedural scripting with the flexibility and power of a full programming language. An overview of currently available applications of MolTalk is given and with PDBChainSaw one such application is described in more detail. PDBChainSaw is a MolTalk-based parser and information extraction utility of PDB files. Weekly updates of the PDB are synchronised with PDBChainSaw and are available for free download from the MolTalk project page http://www.moltalk.org following the link to PDBChainSaw. For each chain in a protein structure, PDBChainSaw extracts the sequence from its co-ordinates and provides additional information from the PDB-file header section, such as scientific organism, compound name, and EC code. MolTalk provides a rich set of methods to analyse and even modify experimentally determined or modelled protein structures. These methods vary in complexity and are thus suitable for beginners and advanced programmers alike. We envision MolTalk to be most valuable in the following applications:1) To analyse protein structures repetitively in large-scale, i.e. to benchmark protein structure prediction methods or to evaluate structural models. The quality of the resulting 3D-models can be assessed by e.g. calculating a Ramachandran-Sasisekharan plot.2) To quickly retrieve information for (a limited number of

2014-07-01

Converging evidence indicates that brain abnormalities in autism spectrum disorder (ASD) involve atypical network connectivity, but it is unclear whether altered connectivity is especially prominent in brain networks that participate in social cognition. To investigate whether adolescents with ASD show altered functional connectivity in 2 brain networks putatively impaired in ASD and involved in social processing, theory of mind (ToM) and mirror neuron system (MNS). Cross-sectional study using resting-state functional magnetic resonance imaging involving 25 adolescents with ASD between the ages of 11 and 18 years and 25 typically developing adolescents matched for age, handedness, and nonverbal IQ. Statistical parametric maps testing the degree of whole-brain functional connectivity and social functioning measures. Relative to typically developing controls, participants with ASD showed a mixed pattern of both over- and underconnectivity in the ToM network, which was associated with greater social impairment. Increased connectivity in the ASD group was detected primarily between the regions of the MNS and ToM, and was correlated with sociocommunicative measures, suggesting that excessive ToM-MNS cross talk might be associated with social impairment. In a secondary analysis comparing a subset of the 15 participants with ASD with the most severe symptomology and a tightly matched subset of 15 typically developing controls, participants with ASD showed exclusive overconnectivity effects in both ToM and MNS networks, which were also associated with greater social dysfunction. Adolescents with ASD showed atypically increased functional connectivity involving the mentalizing and mirror neuron systems, largely reflecting greater cross talk between the 2. This finding is consistent with emerging evidence of reduced network segregation in ASD and challenges the prevailing theory of general long-distance underconnectivity in ASD. This excess ToM-MNS connectivity may reflect

Cultura Obscura: Race, Power, and "Culture Talk" in the Health Sciences.

Science.gov (United States)

Benjamin, Ruha

2017-05-01

"The price of culture is a Lie." 1 This Article advances a critical race approach to the health sciences by examining "culture talk" as a discursive repertoire that attributes distinct beliefs, behaviors, and dispositions to ethno-racialized groups. Culture talk entails a twofold process of obfuscation - concealing the social reality of the people it describes and hiding the positionality of those who employ cultural generalizations. After tracing how culture talk circulates and reproduces racist narratives in and beyond the health sciences, I examine how cultural competency training in medical schools and diversity initiatives in stem cell research use the idiom of culture to manage and manufacture group differences. From culturing cells in the lab to enculturing people in the clinic, I apply the concept of coproduction to argue that culture talk is a precondition and product of scientific knowledge construction.

DeepTalk: A complete conference in a picture

International Nuclear Information System (INIS)

Watts, Gordon

2010-01-01

Particle physics conferences lasting a week (like CHEP) can have 100's of talks and posters presented. Current conference web interfaces (like Indico) are well suited to finding a talk by author or by time-slot. However, browsing the complete material in a modern large conference is not user friendly. Browsing involves continually making the expensive transition between HTML viewing and talk-slides (which are either PDF files or some other format). Further the web interfaces aren't designed for undirected browsing. The advent of multi-core computing and advanced video cards means that we have more processor power available for visualization than any time in the past. This poster describes a technique of rendering a complete conference's slides and posters as a single very large picture. Standard plug-in software for a browser allows a user to zoom in on a portion of the conference that looks interesting. As the user zooms further more and more details become visible, allowing the user to make a quick and chep decision on whether to spend more time on a particular talk. The project, DeepConference, has been implemented as a public web site and can render any conference whose agenda is powered by Indico. The rendering technology is powered by the free download, Silverlight. The poster discusses the implementation and use as well as cross platform performance and possible future directions. A demo will be shown.

Talking Circles for Adolescent Girls in an Urban High School

Directory of Open Access Journals (Sweden)

Ann Schumacher

2014-10-01

Full Text Available Restorative Practices (RP in schools is a new and emerging field. Meeting in Circles to build friendships, develop emotional literacy skills, resolve conflict, or learn interactively are some of the core components of these programs. This article describes a 2-year study of 12 weekly Talking Circles organized under the auspices of a RP program in an urban high school with 60 adolescent girls. Primary data sources included 257 hr of participant observations in Talking Circles and individual, semi-structured interviews with 31 students. The Relational Cultural model, rooted in the work of Jean Baker Miller, served as the conceptual framework for understanding teens’ interactions within the Circle’s unique set of social conditions in a school environment. Findings demonstrated that Talking Circles provided a safe space for peers helping peers, and that the girls improved their listening, anger management, and empathic skills, which led to greater self-efficacy. It appears that Talking Circles could provide another venue for developing social-emotional literacy skills and growth-fostering relationships in schools.

2017-06-01

Increasingly over the past decade, faculty in medical and graduate schools have received requests from digital millennial learners for concise faculty-made educational videos. At our institution, over the past couple of years alone, several hundred educational videos have been created by faculty who teach in a flipped-classroom setting of the pre-clinical medical school curriculum. Despite the appeal and potential learning benefits of digital chalk-talk videos first popularized by Khan Academy, we have observed that the conceptual and technological barriers for creating chalk-talk videos can be high for faculty. To this end, this tips article offers an easy-to-follow 12-step conceptual framework to guide at-home production of chalk-talk educational videos.

Comparing UV/EUV line parameters and magnetic field in a quiescent prominence with tornadoes

Levens, P. J.; Labrosse, N.; Schmieder, B.; López Ariste, A.; Fletcher, L.

2017-10-01

Context. Understanding the relationship between plasma and the magnetic field is important for describing and explaining the observed dynamics of solar prominences. Aims: We determine if a close relationship can be found between plasma and magnetic field parameters, measured at high resolution in a well-observed prominence. Methods: A prominence observed on 15 July 2014 by the Interface Region Imaging Spectrograph (IRIS), Hinode, the Solar Dynamics Observatory (SDO), and the Télescope Héliographique pour l'Étude du Magnétisme et des Instabilités Solaires (THEMIS) is selected. We perform a robust co-alignment of data sets using a 2D cross-correlation technique. Magnetic field parameters are derived from spectropolarimetric measurements of the He I D3 line from THEMIS. Line ratios and line-of-sight velocities from the Mg II h and k lines observed by IRIS are compared with magnetic field strength, inclination, and azimuth. Electron densities are calculated using Fe xii line ratios from the Hinode Extreme-ultraviolet Imaging Spectrometer, which are compared to THEMIS and IRIS data. Results: We find Mg II k/h ratios of around 1.4 everywhere, similar to values found previously in prominences. Also, the magnetic field is strongest ( 30 G) and predominantly horizontal in the tornado-like legs of the prominence. The k3 Doppler shift is found to be between ±10 km s-1 everywhere. Electron densities at a temperature of 1.5 × 106 K are found to be around 109 cm-3. No significant correlations are found between the magnetic field parameters and any of the other plasma parameters inferred from spectroscopy, which may be explained by the large differences in the temperatures of the lines used in this study. Conclusions: This is the first time that a detailed statistical study of plasma and magnetic field parameters has been performed at high spatial resolution in a prominence. Our results provide important constraints on future models of the plasma and magnetic field in

Cain, Jeff

2016-12-25

Objective. To implement and assess an elective course designed to enhance student creative thinking and presentation skills. Design. A two-credit elective course was developed that incorporated creative-thinking exercises, article discussions pertaining to creativity, TED Talk (TED Conferences, New York, NY) analyses, and presentation design and delivery exercises. Assessment. Assessment instruments included pre- and post-course Torrance Tests of Creative Thinking (TTCT). A scoring rubric was developed and used to evaluate a final mock TED Talk presented to faculty and students. Course evaluations were also used to assess student experiences in the course. Students' TTCT verbal creativity scores increased significantly ( p <0.05) during the course and their mock TED Talk mean scores (135±6.4) out of 150 were rated highly. Conclusion. The outcomes from this elective course confirmed that pharmacy students could develop and present an original "idea worth sharing" using the TED Talk format.

Patients' willingness to talk to others about living kidney donation.

2008-03-01

Living donor kidney transplantation has several advantages for patients with end-stage renal disease. However, many patients are reluctant to pursue this treatment option, preferring instead to wait for a deceased donor organ. To examine predictors of patients' willingness to talk to others about living kidney donation. One hundred thirty-two adult patients awaiting kidney transplantation who were enrolled in a randomized trial examining the effectiveness of education on rates of live donor kidney transplantation completed a baseline rating of their willingness to talk to others about living kidney donation. Also, patients completed measures of knowledge and concerns about living donation and a rating of perceived health. Slightly more than half the patients (56.1%) had low willingness to talk to others about living donation. The following variables were associated with higher willingness to talk to others: white race (odds ratio, 3.31; confidence interval, 1.7-7.4), college education (odds ratio, 3.43, confidence interval, 2.0-5.6), fewer concerns about living donor kidney transplantation (odds ratio, 0.31; confidence interval, 0.2-0.6), and less favorable perceptions of their current health status (odds ratio, 4.31; confidence interval, 2.6-7.6). White race, more education, less concern about living donor kidney transplantation, and poorer perceived health are associated with greater willingness to talk to others about living kidney donation. These findings have important implications for educating patients about living donor kidney transplantation.

Puncturing the pipeline: Do technology companies alienate women in recruiting sessions?

Science.gov (United States)

Wynn, Alison T; Correll, Shelley J

2018-02-01

A 'chilly' environment limits women's advancement through the educational pipeline leading to jobs in science and technology. However, we know relatively little about the environment women encounter after making it through the educational pipeline. Do technology companies create environments that may dampen women's interest at the juncture when they are launching their careers? Using original observational data from 84 recruiting sessions hosted by technology companies at a prominent university on the US West Coast, we find that company representatives often engage in behaviors that are known to create a chilly environment for women. Through gender-imbalanced presenter roles, geek culture references, overt use of gender stereotypes, and other gendered speech and actions, representatives may puncture the pipeline, lessening the interest of women at the point of recruitment into technology careers.

Kok, Jin Kuan; Li, Ming-Chin

2017-08-01

This study investigates and presents the narratives of Taiwanese women who have reached the young-old stage. The narrative interview method was used for data collection from 12 Taiwanese women. After analysing the recurring themes emerging from the women's life histories, it is found that the meanings of these Taiwanese women's narratives could not be finalised according to traditional Confucian norms. These women rebelled, resisted, and resumed authorship to make changes to their lives in a patriarchal society. The women were reflexive, and had constant struggles. The findings also reveal a prominent characteristic of Taiwanese culture that emphasises relationships. The women were able to pursue their dreams to involve themselves in self-care, leisure, aesthetic activities, and classes for their personal growth and pleasure. Copyright © 2017 Elsevier Inc.

Small talk

Directory of Open Access Journals (Sweden)

Ryszard Przybylski

2016-12-01

Full Text Available The poem Small talk conjures up a communicative situation in which the main character, a newcomer from Poland, answers conventional questions related to their country. Bearing in mind the fact that this poem is set during a military dictatorship, superficial interest in his homeland may trigger a feeling of impatience. This is at least the impression formed if we adopt the perspective defined within the romantic tradition, and when taking into account the conventional poetry of martial law in Poland. Nevertheless, Barańczak retains an ironic distance towards such communicative situations and, as a consequence, does not create poetry that meets most readersʼ expectations. His poetic imperative for verbal art to be the expression of mistrust remains valid.

2015-07-01

Full Text Available This study focuses on the thematic structure of the Sindhi verbs to find theta roles in the Sindhi language. The study tries to answer the research questions; “What are the thematic structures of Sindhi verbs?” and “What are the prominent theta roles in the Sindhi language?” It examines the argument/thematic structure of Sindhi verbs and also finds the theta roles assigned by the Sindhi verbs to their arguments along with the most prominent theta roles used in the Sindhi language. The data come from the two interviews taken from two young native Sindhi speakers, which consist of 2 hours conversation having 1,669 sentences in natural spoken version of the Sindhi language. Towards the end, it has been found that the Sindhi language has certain theta roles which are assigned by the verbs to their arguments in sentences. Each verb phrase in our data is thus examined and studied in detail in terms of Argument/Thematic structure in order to find theta roles in Sindhi language. Thus, in this regard, each verb phrase (in a sentence has been examined with the help of Carnie’s theoretical framework (Thematic Relation and Theta Roles: 2006 in order to find the prominent theta roles in the Sindhi language. The data have been examined and analysed on the basis of the Carnie’s theoretical framework. The study finds that the Sindhi language has all (09 theta roles which have been proposed by Carnie (2006. It has been found that six prominent theta roles out of nine are used prominently in Sindhi. The six prominent theta roles in Sindhi language are: agent, theme, beneficiary, recipient, locative and goal.

Disease awareness advertising - women's intentions following exposure.

Hall, Danika; Jones, Sandra; Iverson, Don

2011-03-01

In Australia, where direct to consumer advertising of prescription medicines is prohibited, pharmaceutical companies can sponsor disease awareness advertising targeting consumers. This study examined the impact of disease awareness advertising exposure on older women's reported behavioural intentions. Women were approached in a shopping centre and randomly assigned mock advertisements for two health conditions. Disease information and sponsors were manipulated. Two hundred and forty-one women responded to 466 advertisements. Almost half reported an intention to ask their doctor for a prescription or referral as a result of seeing the advertisement, but more reported they would talk to their doctor and ask about treatments and tests. Participants were more likely to report an intention to ask for prescriptions if they perceived the health condition to be severe and themselves susceptible or if they had viewed advertisements containing limited information on the disease. Disease awareness advertising may stimulate demand for prescription medicine products. This has serious implications for general practitioners and regulators.

Women's attitudes toward practicing cytomegalovirus prevention behaviors

Rosemary Thackeray

2016-12-01

Full Text Available Congenital cytomegalovirus (CMV infection causes severe disabilities and developmental delays. Women's awareness of CMV is low. Only about half of healthcare providers report counseling women about behaviors to reduce CMV risk and public health education is limited. Routine CMV counseling is not recommend. Providers may lack time to counsel women; other conditions may take priority for counseling; there may be a perception that women are reluctant to follow advice. This cross-sectional descriptive study examined women's attitudes toward CMV prevention behaviors. Data were collected from an online panel of 840 U.S. women 18–40 years of age, who had a child <5 years of age, and were pregnant or planning a pregnancy in the next 12 months. Questions assessed CMV awareness, frequency of past behaviors that transmit CMV, and attitudes toward eight CMV prevention behaviors. Only 15.5% of women were somewhat or very familiar with CMV. Very few women (6.1% reported hearing from their provider about CMV. Women held positive attitudes toward the CMV prevention behaviors and perceived them as feasible. Least positive attitudes were toward not kissing a child on the lips and not sharing foods. Predictors of positive attitudes were CMV awareness, past behavior, talking to a healthcare provider, and perceived risk reduction. Healthcare providers and public health practitioners should collaborate to increase CMV awareness. Encouraging behaviors to reduce saliva sharing may result in greater gains in reducing CMV infection.

In recent years high-resolution and high-cadence EUV imaging has revealed a new phenomenon, impacting prominence debris, where prominence material from failed or partial eruptions can impact the lower atmosphere and release energy. We present a clear example of this phenomenon occurring on 2011 September 7-8. The initial eruption of prominence material was associated with an X1.8-class flare from AR11283, occurring at 22:30 UT on 2011 September 7, resulting in a semi-continuous stream of this material returning to the solar surface between 00:20 - 00:40 UT on 2011 September 8. A substantial area remote from the original active region experienced brightening in multiple EUV channels observed by SDO/AIA. Using the differential emission measure, we estimated the energetic properties of this event. We found that the radiated energy of the impacted plasma was of order 10^27 ergs, while the upper limit on the thermal energy peaked at 10^28 ergs. Based on these estimates we were able to determine the mass content of the debris to be in the range 2x10^14 energy release takes place during these events, and that such impacts may be used as a novel diagnostic tool for investigating prominence material properties.

A Pharmacy Elective Course on Creative Thinking, Innovation, and TED Talks

Science.gov (United States)

2016-01-01

Objective. To implement and assess an elective course designed to enhance student creative thinking and presentation skills. Design. A two-credit elective course was developed that incorporated creative-thinking exercises, article discussions pertaining to creativity, TED Talk (TED Conferences, New York, NY) analyses, and presentation design and delivery exercises. Assessment. Assessment instruments included pre- and post-course Torrance Tests of Creative Thinking (TTCT). A scoring rubric was developed and used to evaluate a final mock TED Talk presented to faculty and students. Course evaluations were also used to assess student experiences in the course. Students’ TTCT verbal creativity scores increased significantly (p<0.05) during the course and their mock TED Talk mean scores (135±6.4) out of 150 were rated highly. Conclusion. The outcomes from this elective course confirmed that pharmacy students could develop and present an original “idea worth sharing” using the TED Talk format. PMID:28179719

Genetic factors may play a prominent role in the developmentofcoronary heart diseasedependenton important environmental factors. J InternMed2014; 275: 631–639. Objective The aim of the study was to examine whether various lifestyle factors modify genetic influences on coronary heart disease (CHD). Design The effect of lifestyle factors [including smoking, sedentary lifestyle, alcohol intake and body mass index (BMI)] on risk of CHD was evaluated via Cox regression models in a twin study of gene–environment interaction. Using structure equation modelling, we estimated genetic variance of CHD dependent on lifestyle factors. Subjects In total, 51 065 same-sex twins from 25 715 twin pairs born before 1958 and registered in the Swedish Twin Registry were eligible for this study. During the 40-year follow-up, 7264 incident CHD events were recorded. Results Smoking, sedentary lifestyle and above average BMI were significantly associated with increased CHD incidence. The heritability of CHD decreased with increasing age, as well as with increasing levels of BMI, in both men and women. Conclusions The difference in the genetic component of CHD as a function of BMI suggests that genetic factors may play a more prominent role for disease development in the absence of important environmental factors. Increased knowledge of gene–environment interactions will be important for a full understanding of the aetiology of CHD. PMID:24330166

Perng, Shiang-Wuu; Wu, Horng-Wen

2010-01-01

The cell performance enhancement of a proton exchange membrane fuel cell (PEMFC) has been numerically investigated with the prominence-like form catalyst layer surface of the same composition at the cathodic half-cell of a PEMFC. The geometries of the prominence-like form catalyst layer surface are assigned as one prominence, three prominences, and five prominences catalyst layer surfaces with constant distance between two prominences in the same gas diffusion layer (GDL) for the purpose of investigating the cell performance. To confine the current investigation to two-dimensional incompressible flows, we assume that the fluid flow is laminar with a low Reynolds number 15. The results indicate that the prominence-like form catalyst layer surface can effectively enhance the local cell performance of a PEMFC.

Scatter and cross-talk correction for one-day acquisition of 123I-BMIPP and 99mtc-tetrofosmin myocardial SPECT.

123I-15-(p-iodophenyl)-3-(R,S)-methylpentadecanoic acid (BMIPP) and 99mTc-tetrofosmin (TET) are widely used for evaluation of myocardial fatty acid metabolism and perfusion, respectively. ECG-gated TET SPECT is also used for evaluation of myocardial wall motion. These tests are often performed on the same day to minimize both the time required and inconvenience to patients and medical staff. However, as 123I and 99mTc have similar emission energies (159 keV and 140 keV, respectively), it is necessary to consider not only scattered photons, but also primary photons of each radionuclide detected in the wrong window (cross-talk). In this study, we developed and evaluated the effectiveness of a new scatter and cross-talk correction imaging protocol. Fourteen patients with ischemic heart disease or heart failure (8 men and 6 women with a mean age of 69.4 yr, ranging from 45 to 94 yr) were enrolled in this study. In the routine one-day acquisition protocol, BMIPP SPECT was performed in the morning, with TET SPECT performed 4 h later. An additional SPECT was performed just before injection of TET with the energy window for 99mTc. These data correspond to the scatter and cross-talk factor of the next TET SPECT. The correction was performed by subtraction of the scatter and cross-talk factor from TET SPECT. Data are presented as means +/- S.E. Statistical analyses were performed using Wilcoxon's matched-pairs signed-ranks test, and p corrected total count was 26.0 +/- 5.3%. EDV and ESV after correction were significantly greater than those before correction (p = 0.019 and 0.016, respectively). After correction, EF was smaller than that before correction, but the difference was not significant. Perfusion scores (17 segments per heart) were significantly lower after as compared with those before correction (p correction revealed significant differences in EDV, ESV, and perfusion scores. These observations indicate that scatter and cross-talk correction is required for one

1985-08-01

The case histories of 72 women admitted to prison for contempt of court in 1979-83 were reviewed. The sample included 45% of all women imprisoned for contempt in England and Wales over the 5-year period. The contemnors were significantly older than other sentenced prisoners, one third were foreign born and 37.5% were suffering from psychiatric disorder. Two thirds of the mentally disordered group had a paranoid disorder, litigiousness was a prominent feature of their illness, and 52% committed contempt in the context of a matrimonial dispute or a dispute with neighbours. Recent legislation may help to prevent the imprisonment of mentally ill contemnors.

Maternal obesity support services: a qualitative study of the perspectives of women and midwives

Dearden Andy M

2011-10-01

Full Text Available Abstract Background Twenty percent of pregnant women in the UK are obese (BMI ≥ 30 kg/m2, reflecting the growing public health challenge of obesity in the 21st century. Obesity increases the risk of adverse outcomes during pregnancy and birth and has significant cost implications for maternity services. Gestational weight management strategies are a high priority; however the evidence for effective, feasible and acceptable weight control interventions is limited and inconclusive. This qualitative study explored the experiences and perceptions of pregnant women and midwives regarding existing support for weight management in pregnancy and their ideas for service development. Methods A purposive sample of 6 women and 7 midwives from Doncaster, UK, participated in two separate focus groups. Transcripts were analysed thematically. Results Two overarching themes were identified, 'Explanations for obesity and weight management' and 'Best care for pregnant women'. 'Explanations' included a lack of knowledge about weight, diet and exercise during pregnancy; self-talk messages which excused overeating; difficulties maintaining motivation for a healthy lifestyle; the importance of social support; stigmatisation; and sensitivity surrounding communication about obesity between midwives and their clients. 'Best care' suggested that weight management required care which was consistent and continuous, supportive and non-judgemental, and which created opportunities for interaction and mutual support between obese pregnant women. Conclusions Women need unambiguous advice regarding healthy lifestyles, diet and exercise in pregnancy to address a lack of knowledge and a tendency towards unhelpful self-talk messages. Midwives expressed difficulties in communicating with their clients about their weight, given awareness that obesity is a sensitive and potentially stigmatising issue. This indicates more could be done to educate and support them in their work with

Cross-talk and information transfer in mammalian and bacterial signaling.

Directory of Open Access Journals (Sweden)

Samanthe M Lyons

Full Text Available In mammalian and bacterial cells simple phosphorylation circuits play an important role in signaling. Bacteria have hundreds of two-component signaling systems that involve phosphotransfer between a receptor and a response regulator. In mammalian cells a similar pathway is the TGF-beta pathway, where extracellular TGF-beta ligands activate cell surface receptors that phosphorylate Smad proteins, which in turn activate many genes. In TGF-beta signaling the multiplicity of ligands begs the question as to whether cells can distinguish signals coming from different ligands, but transduced through a small set of Smads. Here we use information theory with stochastic simulations of networks to address this question. We find that when signals are transduced through only one Smad, the cell cannot distinguish between different levels of the external ligands. Increasing the number of Smads from one to two significantly improves information transmission as well as the ability to discriminate between ligands. Surprisingly, both total information transmitted and the capacity to discriminate between ligands are quite insensitive to high levels of cross-talk between the two Smads. Robustness against cross-talk requires that the average amplitude of the signals are large. We find that smaller systems, as exemplified by some two-component systems in bacteria, are significantly much less robust against cross-talk. For such system sizes phosphotransfer is also less robust against cross-talk than phosphorylation. This suggests that mammalian signal transduction can tolerate a high amount of cross-talk without degrading information content. This may have played a role in the evolution of new functionalities from small mutations in signaling pathways, allowed for the development of cross-regulation and led to increased overall robustness due to redundancy in signaling pathways. On the other hand the lack of cross-regulation observed in many bacterial two

The aim of this study was to develop a Self-Talk Inventory for young adults. This inventory consisted of two scales. The Negative Self-Talk Scale included three categories of self-talk (depressive, anxious, and angry thoughts) and the Positive Self-Talk Scale, three categories (minimization, positive orientation, and coping self-instructions). Participants were 982 undergraduate students (Mean age = 20.35 years, SD = 2.16). They completed the self-talk scales together with the following scales to measure symptoms of affective disorders: the Center for Epidemiological Studies Depression Scale (CES-D), the State-Trait Anxiety Inventory (STAI), and the State-Trait Anger Expression Inventory (STAXI-T). Factor analyses confirmed the hypothesized structure for the Self-Talk Inventory. The relations between self-talk and symptoms of affective disorders (depression, anxiety, and anger) were also evaluated. In general, states-of-mind -SOM- ratios and negative cognitions showed a greater association with psychological symptoms than did positive cognitions. Results concerning the cognitive characteristics of depression, anxiety, and anger were mixed and partially supported the cognitive content specificity theory.

Effects of temperature on heat pain adaptation and habituation in men and women.

Science.gov (United States)

Hashmi, Javeria A; Davis, Karen D

2010-12-01

We recently reported that women report greater pain adaptation and habituation to moderately painful heat stimuli than men (Hashmi and Davis [16]); but slightly lower temperatures were needed to evoke moderate pain in the women. Hardy et al (1962) and LaMotte (1979) suggested that pain adaptation is most prominent at modest noxious heat temperatures and may occur at temperatures close to pain thresholds. Thus, as a follow-up to our previous study, we examined the role of absolute temperature in pain adaptation and habituation in men and women and assessed whether pain threshold impacts these findings. We hypothesised that pain adaptation and habituation would be more prominent at low and moderate temperatures, and that higher temperatures would induce pain adaptation and habituation in women but not in men. We further hypothesized that pain adaptation would not be correlated with pain thresholds. To test this, we obtained continuous ratings of pain evoked by 44.5-47.5°C stimuli applied to the dorsal foot of men and women. Each run consisted of three 30s stimuli at the same temperature with a 60s inter-stimulus interval. Women showed within-stimulus adaptation of total pain at all temperatures, but men showed significant adaptation to temperatures less than 47°C. There were no sex differences in inter-stimulus habituation and both men and women reported habituation to temperatures less than 46°C. Pain thresholds did not correlate with pain adaptation. These data highlight the temperature-sensitivity and sex differences of pain adaptation and habituation. Copyright © 2010 International Association for the Study of Pain. Published by Elsevier B.V.

2004-01-01

Background Two of the mostly unsolved but increasingly urgent problems for modern biologists are a) to quickly and easily analyse protein structures and b) to comprehensively mine the wealth of information, which is distributed along with the 3D co-ordinates by the Protein Data Bank (PDB). Tools which address this issue need to be highly flexible and powerful but at the same time must be freely available and easy to learn. Results We present MolTalk, an elaborate programming language, which consists of the programming library libmoltalk implemented in Objective-C and the Smalltalk-based interpreter MolTalk. MolTalk combines the advantages of an easy to learn and programmable procedural scripting with the flexibility and power of a full programming language. An overview of currently available applications of MolTalk is given and with PDBChainSaw one such application is described in more detail. PDBChainSaw is a MolTalk-based parser and information extraction utility of PDB files. Weekly updates of the PDB are synchronised with PDBChainSaw and are available for free download from the MolTalk project page following the link to PDBChainSaw. For each chain in a protein structure, PDBChainSaw extracts the sequence from its co-ordinates and provides additional information from the PDB-file header section, such as scientific organism, compound name, and EC code. Conclusion MolTalk provides a rich set of methods to analyse and even modify experimentally determined or modelled protein structures. These methods vary in complexity and are thus suitable for beginners and advanced programmers alike. We envision MolTalk to be most valuable in the following applications: 1) To analyse protein structures repetitively in large-scale, i.e. to benchmark protein structure prediction methods or to evaluate structural models.

2010-03-01

The purpose of this study was to describe women's perceptions of their violent behavior in a heterosexual partnership. The study followed the traditions of Husserlian descriptive phenomenology and the philosophy of existential phenomenology. Twenty-four volunteer Finnish women, aged 19 to 58 years, with a history of different manifestations of intimate partner violence (IPV) participated in open-ended interviews. The data were analyzed by the method developed by Colaizzi. The findings revealed that some of the women who opposed all violence on ethical grounds did not label their behavior as violent; some others minimized or justified their violent behavior. The findings offer professional insight into women's violent behavior and call for a readjustment in approaches to work in the area. Prevention and early identification of IPV require knowledge of the various manifestations and individual meanings of violence. Helping methods should provide women with the opportunity to talk about their abusive behavior and to confront and address their feelings of guilt, disappointment, and shame.

Full Text Available The study entitled. “Language and Interactional Discourse: Deconstructing the Talk - Generating Machinery in Natural Conversation,” is an analysis of spontaneous and informal conversation. The study, carried out in the theoretical and methodological tradition of Ethnomethodology, was aimed at explicating how ordinary talk is organized and produced, how people coordinate their talk –in- interaction, how meanings are determined, and the role of talk in the wider social processes. The study followed the basic assumption of conversation analysis which is, that talk is not just a product of two ‘speakers - hearers’ who attempt to exchange information or convey messages to each other. Rather, participants in conversation are seen to be mutually orienting to, and collaborating in order to achieve orderly and meaningful communication. The analytic objective is therefore to make clear these procedures on which speakers rely to produce utterances and by which they make sense of other speakers’ talk. The datum used for this study was a recorded informal conversation between two (and later three middle- class civil servants who are friends. The recording was done in such a way that the participants were not aware that they were being recorded. The recording was later transcribed in a way that we believe is faithful to the spontaneity and informality of the talk. Our finding showed that conversation has its own features and is an ordered and structured social day by- day event. Specifically, utterances are designed and informed by organized procedures, methods and resources which are tied to the contexts in which they are produced, and which participants are privy to by virtue of their membership of a culture or a natural language community.  Keywords: Language, Discourse and Conversation

'Stratified Contraception': Emergency Contraceptive Pills and Women's Differential Experiences in Contemporary India.

Science.gov (United States)

Sheoran, Nayantara

2015-01-01

Available without prescriptions in India since 2005, emergency contraceptive pills (ECPs) and their advertisements have provided women with increased contraceptive options and a vocabulary to talk about their reproductive lives. I draw on long-term fieldwork with women in urban India about ECPs, demonstrating a new form of 'stratified contraception' enabled by these pills and their advertisements. I posit that there are within India spaces that replicate the luxuries and privileges of the global North. These material conditions, I suggest, are replicated when it comes to contraception as there are hubs of women consumers of contraception and contraceptive advertising that participate in an 'imagined cosmopolitanism' within the global South in close proximity to 'contraceptive ghettos.' Moving beyond simplistic binaries, I outline three major stratifications along which women experience this medical technology and outline the implications for women and their contraceptive choices when notions of northern privilege exist in the 'South.'

2010-01-01

The purpose of this focused ethnographic inquiry was to examine South Asian immigrant women's experiences and perceptions of respect within health professional-client relationships in the context of a Canadian outpatient treatment clinic. Characteristics of respect described by 11 women interviewed were the meaning of respect, health professional's way of being, their way of attending to the person, and their way of talking. Language, cultural values and beliefs, along with underlying societal, individual and institutional factors that coexist with health professionals' ability to create respect were some of the dimensions that influenced how immigrant women experienced respect. Health professionals' capacity to acknowledge South Asian immigrant women as individuals helped to formulate/construct respect for their individual identities. The need to be respected for 'my social identity' as an immigrant woman with cancer was woven throughout women's stories, illustrated by their personal experiences and perspectives.

Subcision Using a Spinal Needle Cannula and a Thread for Prominent Nasolabial Fold Correction

Full Text Available Deepening of the nasolabial crease is an esthetically unpleasing aging phenomenon occurring in the midface. Various treatment modalities have been introduced to improve the appearance of prominent nasolabial folds, all of which have pros and cons. Currently, a minimally invasive technique using synthetic dermal fillers is most commonly used. A simple and easy subcision procedure using a wire scalpel has also been used and reported to be effective for prominent nasolabial fold correction, with minimal complications. As an alternative to the wire scalpel, we used a 20-gauge metal type spinal needle cannula (Hakko Co. and 4-0 Vicryl suture (Ethicon Inc. for subcision of nasolabial folds. This technique is less expensive than the use of a wire scalpel and easily available when needed. Therefore, on the basis of favorable results, our modified subcision technique may be considered effective for prominent nasolabial fold correction.

The role of prominence in determining the scope of boundary-related lengthening in Greek.

Science.gov (United States)

Katsika, Argyro

2016-03-01

This study aims at examining and accounting for the scope of the temporal effect of phrase boundaries. Previous research has indicated that there is an interaction between boundary-related lengthening and prominence such that the former extends towards the nearby prominent syllable. However, it is unclear whether this interaction is due to lexical stress and/or phrasal prominence (marked by pitch accent) and how far towards the prominent syllable the effect extends. Here, we use an electromagnetic articulography (EMA) study of Greek to examine the scope of boundary-related lengthening as a function of lexical stress and pitch accent separately. Boundaries are elicited by the means of a variety of syntactic constructions.. The results show an effect of lexical stress. Phrase-final lengthening affects the articulatory gestures of the phrase-final syllable that are immediately adjacent to the boundary in words with final stress, but is initiated earlier within phrase-final words with non-final stress. Similarly, the articulatory configurations during inter-phrasal pauses reach their point of achievement later in words with final stress than in words with non-final stress. These effects of stress hold regardless of whether the phrase-final word is accented or de-accented. Phrase-initial lengthening, on the other hand, is consistently detected on the phrase-initial constriction, independently of where the stress is within the preceding, phrase-final, word. These results indicate that the lexical aspect of prominence plays a role in determining the scope of boundary-related lengthening in Greek. Based on these results, a gestural account of prosodic boundaries in Greek is proposed in which lexical and phrasal prosody interact in a systematic and coordinated fashion. The cross-linguistic dimensions of this account and its implications for prosodic structure are discussed.

Though parental modeling is thought to play a critical role in promoting children's healthy eating, little research has examined maternal food intake and maternal food talk as independent predictors of children's food intake. The present study examines maternal food talk during a structured eating protocol, in which mothers and their children had the opportunity to eat a series of familiar and unfamiliar vegetables and desserts. Several aspects of maternal talk during the protocol were coded, including overall food talk, directives, pronoun use, and questions. This study analyzed the predictors of maternal food talk and whether maternal food talk and maternal food intake predicted children's food intake during the protocol. Higher maternal body mass index (BMI) predicted lower amounts of food talk, pronoun use, and questions. Higher child BMI z-scores predicted more first person pronouns and more wh-questions within maternal food talk. Mothers of older children used fewer directives, fewer second person pronouns, and fewer yes/no questions. However, maternal food talk (overall and specific types of food talk) did not predict children's food intake. Instead, the most robust predictor of children's food intake during this protocol was the amount of food that mothers ate while sitting with their children. These findings emphasize the importance of modeling healthy eating through action and have implications for designing interventions to provide parents with more effective tools to promote their children's healthy eating.

Study Objective Produce Girl Talk, a free smartphone application containing comprehensive sexual health information, and determine the application’s desirability and appeal among teenage girls. Design, Setting and Participants 39 girls ages 12–17 from Rhode Island participated in a two-phase prospective study. In Phase I, 22 girls assessed a sexual health questionnaire in focus groups. In Phase 2, 17 girls with iPhones® used Girl Talk for two weeks and answered the revised sexual health questionnaire and interview questions before and after use. Main Outcome Measures Participants’ responses to the sexual health questionnaire, interviews and time viewing the application were used to determine feasibility and desirability of Girl Talk. Results Girl Talk was used on average for 48 minutes during participants’ free time on weekends for 10–15 minute intervals. Reported usefulness of Girl Talk as a sexual health application increased significantly from baseline to follow-up (35.3% vs. 94.1%; p < .001). Knowledge improved most in topics related to Anatomy and Physiology (4.2%), Sexuality and Relationships (3.5%) and STI Prevention (3.4%). Most participants (76.5%) were exposed to sexual health education prior to using Girl Talk, but 94.1% of participants stated that the application provided new and/or more detailed information than health classes. Conclusion Girl Talk can potentially connect teenage girls to more information about sexual health versus traditional methods, and participants recommended the application as a valuable resource to learn about comprehensive sexual health.

OZ Minerals' Prominent Hill copper- gold concentrator is located 130 km south east of the town of Coober Pedy in the Gawler Craton of South Australia. The concentrator was built in 2008 and commenced commercial production in early 2009. The Prominent Hill concentrator is comprised of a conventional grinding and flotation processing plant with a 9.6 Mtpa ore throughput capacity. The flotation circuit includes six rougher cells, an IseMill for regrinding the rougher concentrate and a Jameson cell heading up the three stage conventional cell cleaner circuit. In total there are four level controllers in the rougher train and ten level controllers in the cleaning circuit for 18 cells. Generic proportional — integral and derivative (PID) control used on the level controllers alone propagated any disturbances downstream in the circuit that were generated from the grinding circuit, hoppers, between cells and interconnected banks of cells, having a negative impact on plant performance. To better control such disturbances, FloatStar level stabiliser was selected for installation on the flotation circuit to account for the interaction between the cells. Multivariable control was also installed on the five concentrate hoppers to maintain consistent feed to the cells and to the IsaMill. An additional area identified for optimisation in the flotation circuit was the mass pull rate from the rougher cells. FloatStar flow optimiser was selected to be installed subsequent to the FloatStar level stabiliser. This allowed for a unified, consistent and optimal approach to running the rougher circuit. This paper describes the improvement in the stabilisation of the circuit achieved by the FloatStar level stabiliser by using the interaction matrix between cell level controllers and the results and benefits of implementing the FloatStar flow optimiser on the rougher train.

Solar prominence models used so far in the analysis of MHD waves in two-dimensional structures are quite elementary. In this work, we calculate numerically magnetohydrostatic models in two-dimensional configurations under the presence of gravity. Our interest is in models that connect the magnetic field to the photosphere and include an overlying arcade. The method used here is based on a relaxation process and requires solving the time-dependent nonlinear ideal MHD equations. Once a prominence model is obtained, we investigate the properties of MHD waves superimposed on the structure. We concentrate on motions purely two-dimensional, neglecting propagation in the ignorable direction. We demonstrate how, by using different numerical tools, we can determine the period of oscillation of stable waves. We find that vertical oscillations, linked to fast MHD waves, are always stable and have periods in the 4-10 minute range. Longitudinal oscillations, related to slow magnetoacoustic-gravity waves, have longer periods in the range of 28-40 minutes. These longitudinal oscillations are strongly influenced by the gravity force and become unstable for short magnetic arcades.

Time Well Spent in a Kindergarten Class:A Teacher’s Reflection on Using Talk to Learn

Directory of Open Access Journals (Sweden)

Laura Hope-Southcott

2010-06-01

Full Text Available Recent changes in the Ontario curricular expectations for teaching and learning have led the author to re-examine some of her teaching practices, particularly in oral language learning. In this article, the author explores what learning through talk looks like, sounds like and feels like from the kindergarten teacher’s perspective. By inquiring into her own practice, drawing from the literature on classroom talk in the early years, and critically reflecting on vignettes of classroom talk as well as a teaching journal, the author as kindergarten teacher challenges her own assumptions about talk to gain a deeper understanding of its role in a kindergarten classroom. The vignettes, reflective writing and teaching journal act as signposts that map a growing understanding of talk as a tool for learning. These stories help to ground the discussion about talk in practice as well as theory, and provide insights into the challenges and opportunities of using talk for learning in kindergarten.

From rhetoric to reality? Putting HIV and AIDS rights talk into practice in a South African rural community.

Whilst international rhetoric on HIV and AIDS frequently invokes discourses of human rights to inspire and guide action, translating universal rights talk into practice in specific settings remains a challenge. Community mobilisation is often strategy of choice. We present a case study of the Entabeni Project in South Africa--in which a foreign-funded NGO sought to work with female health volunteers in a deep rural community to increase their access to two HIV-relevant rights: women's rights (especially gender equality) and rights to health (especially access to HIV- and AIDS-related services). Whilst the project had short-term health-related successes, it was less successful in implementing a gender empowerment agenda. The concept of women's rights had no purchase with women who had little interest in directly challenging male power, foregrounding the fight against poverty as their main preoccupation. The area's traditional chief and gatekeeper insisted the project should remain 'apolitical'. Project funders prioritised 'numbers reached' over a gender empowerment orientation. In the absence of (1) a marginalised group who are willing to assert their rights; and (2) a context where powerful people are willing to support these claims, 'rights' may be a blunt tool for HIV-related work with women in deeply oppressive and remote rural communities beyond the reach of international treaties and urban-based activist movements.

A model of 'disparitions brusques' (sudden disappearance of eruptive prominences) as an instability driven by MHD waves

A mode of 'disparitions brusques' (sudden disappearance of eruptive prominences) is discussed based on the Kippenhahn and Schluter configuration. It is shown that Kippenhahn and Schluter's current sheet is very weakly unstable against magnetic reconnecting modes during the lifetime of quiescent prominences. Disturbances in the form of fast magnetosonic waves originating from nearby active regions or the changes of whole magnetic configuration due to newly emerged magnetic flux may trigger a rapid growing instability associated with magnetic field reconnection. This instability gives rise to disruptions of quiescent prominences and also generates high energy particles. (author)

Mi'kmaq women are reported to have lower rates of Papanicolaou (Pap) screening and higher rates of cervical cancer than non-Aboriginal women. This qualitative participatory study used postcolonial feminist perspectives and Indigenous principles to explore Mi'kmaq women's experiences with Pap screening within the contexts that shaped their experiences. Community facilitators assisted with the research process. Talking circles and individual in-depth interviews were conducted with 16 Mi'kmaq women. Also, health-care providers were interviewed in 2 Mi'kmaq communities. The findings indicate that historical and social contexts are shaping Mi'kmaq women's screening experiences and that these experiences are diverse, as are their understandings about screening. Some women were accessing regular screening despite challenging personal circumstances. The results highlight the need for nurses and other health-care providers to understand the uniqueness of each woman's experiences with Pap screening. Improvements in screening rates depend on multifaceted nursing approaches developed in partnership with Mi'kmaq women. Copyright© by Ingram School of Nursing, McGill University.

The present paper attempts to frame the description of the hypothetical market so as to induce more “true market behaviour” in the respondents by including a short Cheap Talk script. The script informs respondents that in similar studies using stated preference methods, people have...... to be a preference mover, but does not affect preferences significantly. Significant effects are found when relating the effect of the Cheap Talk script to the cost levels of the alternatives, in that female respondents are found to choose higher cost alternatives less frequently when presented with the Cheap Talk...

Prospects for 6-party talks: Nuclear weapons are a means of survival for Kim Jong Un

International Nuclear Information System (INIS)

Miyake, Kunihiko

2012-04-01

The author considers the impact of leader Kim Jong Il's death on 6-party talks surrounding the nuclear issue. Firstly, the history of these 6-party talks has to be reexamined to ensure an accurate understanding of their 'objectives and limitations' because the author believes that there are 3 'unpleasant truths' behind these talks, held 6 times since the summer of 2003, that no one wants to talk about. 1. North Korea has no interest in abandoning nuclear weapons; 2. Japan, the U.S., China, and South Korea do not want war; 3. The nuclear issue will not be resolved by 6-party talks. In fact, there is little potential that 6-party talks which aim to resolve the North Korean nuclear issue will move towards a new substantive agreement

Full Text Available This article presents the findings from a narrative study that examined the leadership development and pathways of nine prominent Hmong American women leaders from Minnesota and California. Each of these women was able to break through the cultural and gender glass ceiling to become positional and influential leaders in mainstream American society. The study focused on the factors that contributed to the participants leadership development; strategies used in attaining and maintaining leadership roles; and barriers each participant encountered on her path to becoming a leader. Important findings included the impact of poverty, the prominent role of education, inner strength the women possessed, importance of networking and support systems, and strong role models. Other factors included familial responsibilities, gender disparities, racism and ageism. The conceptual frameworks of Belenky, Clinchy, Goldberger and Tarule (1986, and Alon and Higgins (2005, were utilized to guide the analysis and presentation of each participants life journey, and show the intersections between culture and feminist epistemology. The narrative case study approach included in-depth interviews, collective story mapping and re-narration techniques to explore the lives of these women leaders. One overarching goal of the study and this article is to create a greater understanding of complex issues and impediments associated with leadership development, with the hope of beginning a dialog that will help facilitate policy changes regarding developing and supporting minority women in leadership roles.
