a daughter now man man”: heteroglossic and intersectional constructions of fatherhood in the spontaneous talk of a group of young southeast London men

This paper provides an insight into the heteroglossic and intersectional construction of fatherhood in the self-recorded, spontaneous talk of a group of young men from ethnically and racially mixed working-class backgrounds in southeast London. By adopting an interactional sociolinguistic approach, informed by Bakhtin’s (1981; 1984; 1986) work on dialogicality and Tannen’s (1989; 2004) notion of constructed dialogue, this paper explores the young men’s use of voices for their positioning in a range of fathering discourses which are shaped by and shape intersectional and hegemonic masculinities. Intersections of race, ethnicity and social class inform many of the young men’s positions, especially in their talk about the influences of hip hop on their children. This polyphony of voices allows the group to balance traditional discourses of fathers as providers, protectors and moral guides with contemporary models of intimate and involved fatherhood, but also competing discourses of virile masculinity and bad boy identity. of in the

we argue, be mediated by syntax. Our Experiments 1–4 examined the processing of both implicit (short passive) and explicit (active or long passive) control in both local and remote conﬁgurations. Experiments 3 and 4 added either “3 days ago” or “just in order” to the local conditions, to control for the distance between the passive and inﬁnitival verbs, and for the predictability of the reason clause, respectively. We replicate the ﬁnding that implicit control does not impose an additional processing cost. But critically we show that remote control does not impose a processing cost either. Reading times at the reason clause were never slower when control was remote. In fact they were always faster. Thus, efﬁcient processing of local implicit control cannot show that implicit control is mediated by syntax; nor, in turn, that there is a silent but grammatically active argument in passives.
Visual Orbits of Spectroscopic Binaries with the CHARA Array. I. HD 224355

We present the visual orbit of the double-lined spectroscopic binary HD 224355 from interferometric observations with the CHARA Array, as well as an updated spectroscopic analysis using echelle spectra from the Apache Point Observatory 3.5 m telescope. By combining the visual and spectroscopic orbital solutions, we find the binary components to have masses of M1 = 1.626 ± 0.005M⊙ and M2 = 1.608 ± 0.005M⊙, and a distance of d = 63.98 ± 0.26 pc. Using the distance and the component angular diameters found by fitting spectrophotometry from the literature to spectral energy distribution models, we estimate the stellar radii to be R1 = 2.65 ± 0.21R⊙ and R2 = 2.47 ± 0.23R⊙. We then compare these observed fundamental parameters to the predictions of stellar evolution models, finding that both components are evolved toward the end of the main sequence with an estimated age of 1.9 Gyr.
Abell 2384: the galaxy population of a cluster post-merger

We combine multi-object spectroscopy from the 2dF and EFOSC2 spectrographs with optical imaging of the inner 30'x30' of A2384 taken with the ESO Wide Field Imager. We carry out a kinematical analysis using the EMMIX algorithm and biweight statistics. We address the possible presence of cluster substructures with the Dressler-Shectman test. Cluster galaxies are investigated with respect to [OII] and H{\alpha} equivalent width. Galaxies covered by our optical imaging observations are additionally analysed in terms of colour, star formation rate and morphological descriptors such as Gini coefficient and M20 index. We study cluster galaxy properties as a function of clustercentric distance and investigate the distribution of various galaxy types in colour-magnitude and physical space. The Dressler-Shectman test reveals a substructure in the east of the 2dF field-of-view. We determine the mass ratio between the northern and southern subcluster to be 1.6:1. In accordance with other cluster studies, we find that a large fraction of the disk galaxies close to the cluster core show no detectable star formation. Probably these are systems which are quenched due to ram-pressure stripping. The sample of quenched disks populates the transition area between the blue cloud and the red sequence in colour-magnitude space. We also find a population of morphologically distorted galaxies in the central cluster region. The substructure in the east of A2384 might be a group of galaxies falling onto the main cluster. We speculate that our sample of quenched spirals represents an intermediate phase in the ram-pressure driven transformation of infalling field spirals into cluster S0s. This is motivated by their position in colour-magnitude space. The occurrence of morphologically distorted galaxies in the cluster core complies with the hypothesis of A2384 representing a post merger system.
Spatially resolved kinematic observations of the planetary nebulae Hen 3-1333 and Hen 2-113★

We have performed integral field spectroscopy of the planetary nebulae Hen 3-1333 (PNG332.9-09.9) and Hen 2-113 (PNG321.0+03.9), which are unusual in exhibiting dual-dust chemistry and multipolar lobes but also ionized by late-type [WC 10] central stars. The spatially resolved velocity distributions of the H$\alpha$ emission line were used to determine their primary orientations. The integrated H$\alpha$ emission profiles indicate that Hen 3-1333 and Hen 2-113 expand with velocities of ~ 32 and 23 km/s, respectively. The Hubble Space Telescope observations suggest that these planetary nebulae have two pairs of tenuous lobes extending upwardly from their bright compact cores. From three-dimensional geometric models, the primary lobes of Hen 3-1333 and Hen 2-113 were found to have inclination angles of about -30$^{\circ}$ and 40$^{\circ}$ relative to the line of sight, and position angles of -15$^{\circ}$ and 65$^{\circ}$ measured east of north in the equatorial coordinate system, respectively.
The Caregiver's Conflict: The Toll of Death and Dying on Nurses' Mental Health and Wellbeing

A major responsibility for nurses is caring for patients during the end-of-life process, as well as helping families and patients cope with the death and dying process. It is well known that death and dying greatly impacts families, but little holistic research has been done on how death and dying impacts nurses’ mental and emotional wellbeing. Using databases Google Scholar, Web of Science, and EBSCO, 14 articles were analyzed regarding the impact of death on nurses’ mental health. Results show that the age of a patient plays a bigger role on death impact than nursing specialty does, as younger patients’ deaths cause greater emotional turmoil than older patients. Cultural values around death also affected the emotional impact a patient’s death had on nurses. Nurses from cultures with a more negative attitude towards death experienced greater emotional turmoil when patients died. Religious values were shown to help nurses cope with the dying process. Across studies and specialties, nurses complained of being underprepared to deal with the death and dying process. These common complaints indicate gaps in nursing education that need to be addressed and rectified to preserve the health and mental wellbeing of caregivers.
SPECTRUM AND LIGHT CURVE OF A SUPERNOVA SHOCK BREAKOUT THROUGH A THICK WOLF–RAYET WIND

Wolf–Rayet stars are known to eject winds. Thus, when a Wolf–Rayet star explodes as a supernova, a fast (≳ 40, 000 km s−1) shock is expected to be driven through a wind. We study the signal expected from a fast supernova shock propagating through an optically thick wind and find that the electrons behind the shock driven into the wind are efficiently cooled by inverse Compton over soft photons that were deposited by the radiation-mediated shock that crossed the star. Therefore, the bolometric luminosity is comparable to the kinetic energy flux through the shock, and the spectrum is found to be a power law, whose slope and frequency range depend on the number flux of soft photons available for cooling. Wolf–Rayet supernovae that explode through a thick wind have a high flux of soft photons, producing a flat spectrum, νFν = Const, in the X-ray range of 0.1 ≲ T ≲ 50 keV. As the shock expands into an optically thin wind, the soft photons are no longer able to cool the shock that plows through the wind, and the bulk of the emission takes the form of a standard core–collapse supernova (without a wind). However, a small fraction of the soft photons is upscattered by the shocked wind and produces a transient unique X-ray signature.
BYU ScholarsArchive BYU ScholarsArchive Psychological Sense of Community in Gateway Communities Psychological Sense of Community in Gateway Communities

This paper will expand on community research by analyzing the changes in psychological sense of community in gateway communities. We will look at the rural communities that border the Bears Ears National Monument as a case study, in order to evaluate the impact that land management changes have on gateway communities. Survey data from three rural communities that surround Bears Ears National Monument are used to test the effects a proposed land management change has on community needs fulfillment, community emotional connection, community influence and community membership. We find that when a regression is run, the proposed changes to the land designation significantly affects people’s psychological sense of community. While the literature on gateways communities and psychological sense of community provided a useful framework for the study of rural community’s experience, our conclusion indicates a need to consider rural community experience when proposing land management and designation changes to public lands. Specifically, future research should focus on understanding the community effects of creating a national monument.
Peer review for science funding: a review

Peer review is widely considered the gold standard for evaluating research and indeed it is the most widely means to allocate funds among competing proposals in the sciences. In this chapter we review what we know about the peer review system. We discuss evidence suggesting where the system delivers desired outcomes such as funding the most meriting proposals and where it appears to be prone to shortcomings including biases originating from the gender, status and ethnicity of proposers. We then review alternatives to the traditional peer review such as funding people rather than projects and discuss how these alternatives have performed. We conclude the chapter with suggestions on research avenues that could improve our understanding of what could work in order to improve the allocation of research funds.
Tidal Disruptions of Stars by Black Hole Remnants in Dense Star Clusters

In a dense stellar environment, such as the core of a globular cluster (GC), dynamical interactions with black holes (BHs) are expected to lead to a variety of astrophysical transients. Here we explore tidal disruption events (TDEs) of stars by stellar-mass BHs through collisions and close encounters. Using state-of-the-art cluster simulations, we show that these TDEs occur at significant rates throughout the evolution of typical GCs and we study how their relative rates relate to cluster parameters such as mass and size. By incorporating a realistic cosmological model of GC formation, we predict a BH–main-sequence-star TDE rate of approximately 3 Gpc−3 yr−1 in the local universe (z < 0.1) and a cosmological rate that peaks at roughly 25 Gpc−3 yr−1 for redshift 3. Furthermore, we show that the ejected mass associated with these TDEs could produce optical transients of luminosity ∼1041−1044 erg s−1 with timescales of about a day to a month. These should be readily detectable by optical transient surveys such as the Zwicky Transient Facility. Finally, we comment briefly on BH–giant encounters and discuss how these events may contribute to the formation of BH–white-dwarf binaries.
Critical Care Nurses' Perceptions of End-of-Life Care Obstacles: Critical Care Nurses' Perceptions of End-of-Life Care Obstacles: Comparative 17-Year Data Comparative 17-Year Data

Background: Nurses working in intensive care units (ICUs) frequently care for patients and their families at the end of life (EOL). Providing high-quality EOL care is important for both patients and families, yet ICU nurses face many obstacles that hinder EOL care. Researchers have identified various ICU nurse-perceived obstacles, but no studies have been found addressing the progress that has been made for the last 17 years. Objective: The aims of this study were to determine the most common and current obstacles in EOL care as perceived by ICU nurses and then to evaluate whether meaningful changes have occurred since data were first gathered in 1998. Methods: families, (4) nurses having to deal with angry families, and (5) nurses not knowing their patient " s wishes regarding continuing with tests and treatments. Conclusions: Obstacles in EOL care, as perceived by critical care nurses, still exist. Family-related obstacles have increased over time. Obstacles related to families may not be easily overcome as each family, dealing with a dying family member in an ICU, likely has not previously experienced a similar situation. On the basis of the current top 5 obstacles, recommendations for possible areas of focus include (1) improved health literacy assessment of families followed by earlier directed, appropriate, and specific EOL information; (2) improved physician/team communication; and (3) ensuring patients " wishes are followed as written. In general, patient- and family-centered care using clear and open EOL communication regarding wishes and desires between patients and families, their physicians, and nurses will help decrease common obstacles, thus improving the quality of EOL care provided to dying patients and families.
The tilt of primordial gravitational waves spectra from BICEP2

In this paper we constrain the tilt of the spectrum of primordial gravitational waves from Background Imaging of Cosmic Extragalactic Polarization (BICEP2) data only. We find r = 0.21(-0.10)(+0.04) and n(t) = -0.06(-0.23) (+0.25) (at 68% C.L.) which implies that a scale-invariant primordial gravitational waves spectra is consistent with BICEP2 nicely. Our results provide evidence for supporting inflation model, and the alternative models, for example the ekpyrotic model which predicts n(t) = 2, are ruled out at high significance level.
FINANCIAL INFORMATION WITH THE MODERATION OF FIRM SIZE ON THE STOCK PRICE OF LQ45 ISSUERS

The stock price is an essential factor and must be considered by investors because stock price shows the performance of the company. The stock price also shows the value of a company and is an appropriate index for the effectiveness of the company. Companies that are included in category LQ45 (Liquid 45) are the forty-five dominant listed companies on the Indonesia Stock Exchange. LQ45’s stock price is relatively stable compared to the other companies, even during the current pandemic. This study aims to find empirical evidence regarding the factors that influence and moderate the stock price of LQ45. The independent variables were Price Book Value (PBV), Price Earnings Ratio (PER), profitability proxied by Net Profit Margin (NPM), Debt Equity Ratio (DER), and firm size as moderating variables. This quantitative research uses the purposive sampling technique and EViews 9 for data processing. This study examines the partial influence (t-test), simultaneous influence (f-test), and moderating interaction (Moderated Regression Analysis/ MRA). The partial test results found that PBV, PER, and NPM had some significant influence and DER had an insignificant influence on the stock price. For simultaneous results, all independent variables significantly influence the stock price. Meanwhile, the results of the MRA found that firm size did not moderate (not a moderating variable) the influence of the independent variables on the stock price.
A Study on Evaluation of Custom made Vacuum Assisted Closure in the Management of Non-Healing Ulcers

Introduction: Non-healing ulcers are a major health problem globally and affect the individual personally, professionally and socially. They also pose a burden on the individual and the health care system. Refractory non-healing ulcers are one of the major cause of lower limb amputations attributable to non-traumatic etiology. Wound healing requires frequent and regular dressings which can be done either by conventional method or by Vacuum Assisted Closure (VAC). Aim of the study: To evaluate custom made VAC therapy efficacy as compared to conventional dressings in the treatment of non-healing ulcers. Materials and Methods: A total of 60 patients with non-healing ulcers were put equally into two groups as Group A with 30 patients who received (VAC) dressings and 30 patients in Group B who were given conventional dressings.The cause of the ulcers, the effectiveness of VAC, the cost of treatment, the duration of hospital stay and patient satisfaction were studied and compared. Results: The VAC group had improved wound healing and better patient satisfaction as compared to the conventional dressing group. Conclusion: The application of Vacuum Assisted Closure to non-healing wounds is a good alternative to conventional dressings. It facilitates better wound healing and is cost effective and has overall benefits as compared to conventional dressings.
Evolving images of the proton: Hadron physics over the past 40 years

Once upon a time, the world was simple: the proton contained three quarks, two ups and a down. How these give the proton its mass and its spin seemed obvious. Over the past 40 years the proton has become more complicated, and how even these most obvious of its properties is explained in a universe of quarks, antiquarks and gluons remains a challenge. That this should be so should come as no surprise. Quantum chromodynamics, the theory of the strong interaction, is seemingly simple, and its consequences are straightforward in the domain of hard scattering where perturbation theory applies. However, the beauty of the hadron world is its diversity. The existence of hadrons, their properties, and their binding into nuclei do not appear in the Lagrangian of QCD. They all emerge as a result of its strong coupling. Strong coupling QCD creates complex phenomena, much richer than known 40 years ago: a richness that ensures colour confinement and accounts for more than 95% of the mass of the visible Universe. How strong coupling QCD really works requires a synergy between experiment and theory. A very personal view of these fascinating developments in cold QCD is presented.
Witt groups of abelian categories and perverse sheaves

In this paper we study the Witt groups of symmetric and anti-symmetric forms on perverse sheaves on a finite-dimensional topologically stratified space with even dimensional strata. We show that the Witt group has a canonical decomposition as a direct sum of the Witt groups of shifted local systems on strata. We compare this with another `splitting decomposition' for Witt classes of perverse sheaves obtained inductively from our main new tool, a `splitting relation' which is a generalisation of isotropic reduction. The Witt groups we study are identified with the (non-trivial) Balmer-Witt groups of the constructible derived category of sheaves on the stratified space, and also with the corresponding cobordism groups defined by Youssin. Our methods are primarily algebraic and apply more widely. The general context in which we work is that of a triangulated category with duality, equipped with a self-dual t-structure with noetherian heart, glued from self-dual t-structures on a thick subcategory and its quotient.
STAR FORMATION IN HIGH-REDSHIFT CLUSTER ELLIPTICALS

We measure the star formation rates (SFRs) of massive (M⋆ > 1010.1M☉) early-type galaxies (ETGs) in a sample of 11 high-redshift (1.0 < z < 1.5) galaxy clusters drawn from the IRAC Shallow Cluster Survey (ISCS). We identify ETGs visually from Hubble Space Telescope imaging and select likely cluster members as having either an appropriate spectroscopic redshift or red-sequence color. Mid-infrared SFRs are measured using Spitzer 24 μm data for isolated cluster galaxies for which contamination by neighbors, and active galactic nuclei, can be ruled out. Cluster ETGs show enhanced specific star formation rates (sSFRs) compared to cluster galaxies in the local universe, but have sSFRs more than four times lower than that of field ETGs at 1 < z < 1.5. Relative to the late-type cluster population, isolated ETGs show substantially quenched mean SFRs, yet still contribute 12% of the overall star formation activity measured in 1 < z < 1.5 clusters. We find that new ETGs are likely being formed in ISCS clusters; the fraction of cluster galaxies identified as ETGs increases from 34% to 56% from z ∼ 1.5 → 1.25. While the fraction of cluster ETGs that are highly star-forming (SFR ⩾ 26 M☉ yr−1) drops from 27% to 10% over the same period, their sSFRs are roughly constant. All these factors taken together suggest that, particularly at z ≳ 1.25, the events that created these distant cluster ETGs—likely mergers, at least among the most massive—were both recent and gas-rich.
ScholarWorks @ Georgia State University ScholarWorks @ Georgia State University Paradoxes and Mechanisms for Choice under Risk Paradoxes and Mechanisms for Choice under Risk

: Experiments on choice under risk typically involve multiple decisions by individual subjects. The choice of mechanism for selecting decision(s) for payoff is an essential design feature unless subjects isolate each one of the multiple decisions. We report treatments with different payoff mechanisms but the same decision tasks. The data show large differences across mechanisms in subjects’ revealed risk preferences, a clear violation of isolation. We illustrate the importance of these mechanism effects by identifying their implications for classical tests of theories of decision under risk. We discuss theoretical properties of commonly used mechanisms, and new mechanisms introduced herein, in order to clarify which mechanisms are theoretically incentive compatible for which theories. We identify behavioral properties of some mechanisms that can introduce bias in elicited risk preferences – from cross-task contamination – even when the mechanism used is theoretically incentive compatible. We explain that selection of a payoff mechanism is an important component of experimental design in many topic areas including social preferences, public goods, bargaining, and choice under uncertainty and ambiguity as well as experiments on decisions under risk.
