WHERE DO GALAXIES END?

Our current view of galaxies considers them as systems of stars and gas embedded in extended halos of dark matter, much of it formed by the infall of smaller systems at earlier times. The true extent of a galaxy remains poorly determined, with the “virial radius” (Rvir) providing a characteristic separation between collapsed structures in dynamical equilibrium and external infalling matter. Other physical estimates of the extent of gravitational influence include the gravitational radius, gas accretion radius, and “galactopause” arising from outflows that stall at 100–200 kpc over a range of outflow parameters and confining gas pressures. Physical criteria are proposed to define bound structures, including a more realistic definition of Rvir(M*, Mh, za) for stellar mass M* and halo mass Mh, half of which formed at “assembly redshifts” ranging from za ≈ 0.7–1.3. We estimate the extent of bound gas and dark matter around L* galaxies to be ∼200 kpc. The new virial radii, with mean 〈Rvir〉 ≈ 200 kpc, are 40%–50% smaller than values estimated in recent Hubble Space Telescope/Cosmic Origins Spectrograph detections of H i and O vi absorbers around galaxies. In the new formalism, the Milky Way stellar mass, log M* = 10.7 ± 0.1, would correspond to kpc for half-mass halo assembly at za = 1.06 ± 0.03. The frequency per unit redshift of low-redshift O vi absorption lines in QSO spectra suggests absorber sizes ∼150 kpc when related to intervening 0.1L* galaxies. This formalism is intended to clarify semantic differences arising from observations of extended gas in galactic halos, circumgalactic medium (CGM), and filaments of the intergalactic medium (IGM). Astronomers should refer to bound gas in the galactic halo or CGM, and unbound gas at the CGM–IGM interface, on its way into the IGM.
A Social Robot for Improving Interruptions Tolerance and Employability in Adults with ASD

A growing population of adults with Autism Spec-trum Disorders (ASD) chronically struggles to find and maintain employment. Previous work reveals that one barrier to employment for adults with ASD is dealing with workplace interruptions. In this paper, we present our design and evaluations of an in-home autonomous robot system that aims to improve users' tolerance to interruptions. The Interruptions Skills Training and Assessment Robot (ISTAR) allows adults with ASD to practice handling interruptions to improve their employability. ISTAR is evaluated by surveys of employers and adults with ASD, and a week-long study in the homes of adults with ASD. Results show that users enjoy training with ISTAR, improve their ability to handle various work-relevant interruptions, and view the system as a valuable tool for improving their employment prospects.
A framework for the evaluation of winery servicescapes:A New Zealand case

In an increasingly competitive market to attract visitors, wineries are often seeking new means to enhance the visitor experience. However, despite recognition of the importance in the wine tourism literature of the setting in which wine experiences occur there has been little adoption of the servicescape concept from the marketing literature and its adoption as a potential diagnostic tool. The paper utilizes the concept to develop a potential diagnostic tool that may be used by wineries and cellar door venues to evaluate their servicescape attributes. Preliminary results are provided which demonstrate the utility of the servicescape framework but further research is required to test the framework in different culture and design settings. Abstract: En mercados cada vez mas competitivos, donde se intentan captar mayores cuotas de deman- da, las bodegas buscan a menudo nuevas formas de realzar las experiencias de los visitantes. Sin embar- go, a pesar del reconocimiento de la importancia en la literatura del constructo "turismo del vino" y "ex- periencias del visitante", el ajuste entre estas ultimas y el nuevo concepto de interaccion social (services- cape) como herramienta potencial de diagnostico ha tenido poca atencion en la literatura del marketing. El papel que utiliza el concepto comentado para desarrollar un instrumento de diagnostico potencial, deberia ser usado por las bodegas y distribuidoras para evaluar los atributos de esta llamada "interaccion social". Los resultados preliminares proporcionan y demuestran la utilidad del marco conceptual de la "interaccion social", pero se requiere de investigaciones adicionales en diferentes culturas y entornos, asi como ajustes de diseno del mismo.
The fabric of performance: values and social practices of classical music expressed through concert dress choice

Concert dress is a valuable visual cue to an individual's attitudes and through concert dress soloists can confirm or challenge generally accepted roles and statuses in the performance situation. This article discusses the implications of production- and reception-based models of classical performance for soloists. Female classical soloists' choice of concert dress is examined using Interpretative Phenomenological Analysis (IPA) to investigate whether performers' sartorial de- cisions can provide insight into the social practices and underlying values associ- ated with classical music performance. Six female solo instrumentalists of inter- national standing were interviewed regarding factors affecting their choice of concert dress, how they felt their concert dress interacted with their ability to communicate in performance, and the image they intended to portray in perfor- mance. Emerging themes suggest that performers select dress which allows them physical freedom, the ability to signal their views of performance to their audi- ence, and to display individual characteristics. These themes are discussed in re- lation to production- and reception-based theories of classical performance.
Pragmatic and Cultural Considerations of Compliment Responses among Malaysian-Malay Speakers

Janet Holmes defines a compliment as “a speech act which explicitly or implicitly attributes credit to someone other than the speaker, usually the person addressed, for some „good‟ (possession, characteristic, skill, etc.) which is positively valued by the speaker and the hearer” (485). Compliments vary from one culture to another. As suggested by Holmes (1986), compliments are generally paid and appreciated in the Western culture. However, in the Eastern culture, when compliments are paid, they are either rejected or denied (Gu, 1990; Chen, 1993). Malaysia is a multicultural society with a colonial history. English is spoken widely in the country, side by side with several vernacular languages. The study investigates the pragmatics of Malay compliments using Brown and Levinson‟s (1987) “face” framework and Searle‟s (1969) speech act framework among Malay speakers in Malaysia. The results show that compliments when given are more appreciated than denied or rejected by Malay speakers now than before, indicating a shift in the culture of compliments and compliment response in Malaysia. Results also show that compliment responses differ according to the subject of compliment and its relative “distance” to the compliment receiver; closeness causes more compliment rejections, while distance results in compliment acceptance.
The Evolution of the Warm Absorber Reveals a Shocked Outflow in the Narrow Line Seyfert 1 Galaxy IRAS 17020+4544

We present the analysis of grating spectra of the Narrow Line Seyfert 1 Galaxy IRAS 17020+4544 observed by XMM-Newton in 2004 and 2014. In a previous work on these data, we reported the discovery of a multicomponent ultra-fast outflow that is capable of producing feedback in the host galaxy. We also reported the presence of a slow, multiphase warm absorber (WA). In this follow-up paper, we confirm that this low-velocity absorber can be modeled by four layers of ionized gas. When crossing our line of sight, this gas presents peculiar changes along the 10 yr timescale elapsed between the two observations obtained by XMM-Newton. While two of such components are almost stationary, the other two are found inflowing and outflowing with significant variations in velocity and ionization between 2004 and 2014. The luminosity and spectral shape of the central source remain practically unvaried. We propose that the presence of the fast wind and of the variable WA can be interpreted in the framework of a “shocked outflow,” where the peculiar variability pattern of the low-velocity components might arise from instabilities in the shocked gas.
HIGH QUALITY FUNCTIONAL COVERAGE BASED TRACE SIGNAL SELECTION FOR POST-SILICON VALIDATION BY SAI MA THESIS

Due to the drastic growth of design complexity and also shrinkage of the time-to-market window, it is always impossible to capture all bugs during the pre-silicon verification phase; therefore, a small number of bugs escape after a chip is manufactured. Once a chip is manufactured, it is considered as a black box since internal observability is lost. To increase observability for post-silicon validation, an effective silicon debug technique is to use an on-chip trace buffer to monitor and capture the circuit response of certain selected signals during its post-silicon operation. Since this aforementioned debugging trace buffer introduces area overhead, the amount of signals selected to be stored on this trace buffer is very limited. Therefore, a major challenge in this field is to select a powerful subset of internal signals to reconstruct the majority of the remaining signal values. Existing methods use a greedy selection process to converge to a locally optimal selection; this kind of method suffers from severe diminishing restoration ratio effect as more trace signals are selected. In addition, all of the previous publications have been focused on increasing restorability; none of them has ever been able to interpret the trace signals as high level meaningful debugging information. In this thesis, we formulate the trace signal selection problem into a datamining problem and propose two approaches using PageRank and HITS algorithm. Our experimental results demonstrate that our algorithm can effectively alleviate the diminishing restoration ratio effect. Furthermore, we propose a new metric to evaluate the quality of selected trace signals instead of restorability, which is the number of functionalities they cover when debugging; this is an angle previous publications have not addressed. According to our experimental results, the two new algorithms proposed in this thesis select better and more meaningful trace signals in terms of debugging.
Engineers Consequences of Flexibility Stigma Among Academic Scientists and

Flexibility stigma, the devaluation of workers who seek or are presumed to need flexible work arrangements, fosters a mismatch between workplace demands and the needs of professionals. The authors survey “ideal workers”—science, technology, engineering, and math faculty at a top research university—to determine the consequences of working in an environment with flexibility stigma. Those who report this stigma have lower intentions to persist, worse work–life balance, and lower job satisfaction. These consequences are net of gender and parenthood, suggesting that flexibility stigma fosters a problematic environment for many faculty, even those not personally at risk of stigmatization.
Tissue plasminogen activator antigen and coronary heart disease Prospective study and meta-analysis

Aims To determine whether circulating tissue plasminogen activator (t-PA) antigen concentrations are prospectively related to risk of coronary heart disease (CHD) in the general population Methods and results We measured baseline concentrations of t-PA antigen in the stored serum samples of 606 CHD cases and 1227 controls ‘nested’ in a prospective cohort of 5661 men monitored for 16 years, and conducted a meta-analysis of previous relevant studies to place our findings in context. Tissue plasminogen activator antigen values were strongly correlated with several vascular risk factors, including serum lipids, body mass index, alcohol consumption, and markers of systemic inflammation. In a comparison of men in the top third compared with those in the bottom third of baseline t-PA antigen values, the odds ratio for CHD was 2.20 (95% confidence interval (CI) 1.70–2.85) after adjustment for age and town only, but this fell to 1.48 (1.09–2.01) after further adjustment. Analysis of t-PA as a continuous variable gave similar results. Similarly, when published information on all seven available prospective cohort studies in general populations (2119 cases and 8832 controls in total) was synthesized, the combined odds ratio was 2.18 (1.77–2.69) after adjustment for age and sex only, and this fell to 1.47 (1.19–1.81) after further adjustment. Conclusion Although there is a statistically significant association between circulating concentrations of t-PA antigen and subsequent CHD, additional studies are needed to determine to what extent this is independent from more established risk factors. © 2003 Published by Elsevier Ltd on behalf of The European Society of Cardiology.
Unbundling the Degree Effect in a Job Training Program for Disadvantaged Youth

Government-sponsored education and training programs have the goal to enhance participants' skills so as to become more employable, productive and dependable citizens and thus alleviate poverty and decrease public dependence. While most of the literature evaluating training programs concentrates on estimating their total average treatment effect, these programs offer a variety of services to participants. Estimating the effect of these components is of importance for the design and the evaluation of labor market programs. In this paper, we employ a recent nonparametric approach to estimate bounds on the "mechanism average treatment effect" to evaluate the causal effect of attaining a high school diploma, General Education Development or vocational certificate within a training program for disadvantaged youth 16-24 (Job Corps) relative to other services pffered, on two labor outcomes: employment probability and weekly earnings. We provide these estimates for different demographic groups by race, ethnicity, gender, and two age-risk groups (youth and young adults). Our analysis depicts a positive impact of a degree attainment within the training program on employment probability and weekly earnings for the majority of its participants which in general accounts for 55 - 63 percent of the effect of the program. The heterogeneity of the key demographic subgroups is documented in the relative importance of a degree attainment and of the other services provided in Job Corps.
Massive stars exploding in a He-rich circumstellar medium. IV. Transitional Type Ibn Supernovae

We present ultraviolet, optical and near-infrared data of the Type Ibn supernovae (SNe) 2010al and 2011hw. SN 2010al reaches an absolute magnitude at peak of M-R = -18.86 +/- 0.21. Its early light curve shows similarities with normal SNe Ib, with a rise to maximum slower than most SNe Ibn. The spectra are dominated by a blue continuum at early stages, with narrow P-Cygni He I lines indicating the presence of a slow-moving, He-rich circumstellar medium. At later epochs, the spectra well match those of the prototypical SN Ibn 2006jc, although the broader lines suggest that a significant amount of He was still present in the stellar envelope at the time of the explosion. SN 2011hw is somewhat different. It was discovered after the first maximum, but the light curve shows a double peak. The absolute magnitude at discovery is similar to that of the second peak (M-R = -18.59 +/- 0.25), and slightly fainter than the average of SNe Ibn. Though the spectra of SN 2011hw are similar to those of SN 2006jc, coronal lines and narrow Balmer lines are clearly detected. This indicates substantial interaction of the SN ejecta with He-rich, but not H-free, circumstellar material. The spectra of SN 2011hw suggest that it is a transitional SN Ibn/IIn event similar to SN 2005la. While for SN 2010al the spectrophotometric evolution favours a H-deprived Wolf-Rayet progenitor (of WN-type), we agree with the conclusion of Smith et al. that the precursor of SN 2011hw was likely in transition from a luminous blue variable to an early Wolf-Rayet (Ofpe/WN9) stage.
The merging dwarf galaxy UM 448: chemodynamics of the ionized gas from VLT integral field spectroscopy

Using Very Large Telescope/Fibre Large Array Multi Element Spectrograph optical integral field unit observations, we present a detailed study of UM 448, a nearby blue compact galaxy (BCG) previously reported to have an anomalously high N/O abundance ratio. New Technology Telescope/Superb-Seeing Imager images reveal a morphology suggestive of a merger of two systems of contrasting colour, whilst our Hα emission maps resolve UM 448 into three separate regions that do not coincide with the stellar continuum peaks. UM 448 exhibits complex emission line profiles, with most lines consisting of a narrow [full width at half-maximum (FWHM) ≲ 100 km s-1], central component, an underlying broad component (FWHM ∼ 150–300 km s-1) and a third, narrow blueshifted component. Radial velocity maps of all three components show signs of solid body rotation across UM 448, with a projected rotation axis that correlates with the continuum morphology of the galaxy. A spatially resolved, chemodynamical analysis, based on the [O III] λλ4363, 4959, [N II] λ6584, [S II] λλ6716, 6731 and [Ne III] λ3868 line maps, is presented. Whilst the eastern tail of UM 448 has electron temperatures (Te) that are typical of BCGs, we find a region within the main body of the galaxy where the narrow and broad [O III] λ4363 line components trace temperatures differing by 5000 K and oxygen abundances differing by 0.4 dex. We measure spatially resolved and integrated ionic and elemental abundances for O, N, S and Ne throughout UM 448, and find that they do not agree, possibly due the flux weighting of Te from the integrated spectrum. This has significant implications for abundances derived from long-slit and integrated spectra of star-forming galaxies in the nearby and distant universe. A region of enhanced N/O ratio is indeed found, extended over a ∼0.6 kpc2 region within the main body of the galaxy. Contrary to previous studies, however, we do not find evidence for a large Wolf–Rayet (WR) population, and conclude that WR stars alone cannot be responsible for producing the observed N/O excess. Instead, the location and disturbed morphology of the N-enriched region suggest that interaction-induced inflow of metal-poor gas may be responsible.
outputs AUGUR : Forecasting the Emergence of New Research Topics Conference or Workshop Item

Being able to rapidly recognise new research trends is strategic for many stakeholders, including universities, institutional funding bodies, academic publishers and companies. The literature presents several approaches to identifying the emergence of new research topics, which rely on the assumption that the topic is already exhibiting a certain degree of popularity and consistently referred to by a community of researchers. However, detecting the emergence of a new research area at an embryonic stage, i.e., before the topic has been consistently labelled by a community of researchers and associated with a number of publications, is still an open challenge. We address this issue by introducing Augur, a novel approach to the early detection of research topics. Augur analyses the diachronic relationships between research areas and is able to detect clusters of topics that exhibit dynamics correlated with the emergence of new research topics. Here we also present the Advanced Clique Percolation Method (ACPM), a new community detection algorithm developed specifically for supporting this task. Augur was evaluated on a gold standard of 1,408 debutant topics in the 2000-2011 interval and outperformed four alternative approaches in terms of both precision and recall.
Mild solutions for nonlocal fractional semilinear functional differential inclusions involving Caputo derivative

In this paper, we prove various existence results of a mild solution for a fractional nonlocal functional semilinear differential inclusion involving Caputo derivative in Banach spaces. We consider the case when the values of the orient field are convex as well as nonconvex. Moreover, we study the topological structure of solution sets. Our results extend or generalize results proved in recent papers.
Does Auditor Tenure Improve Audit Quality? Moderating Effects of Industry Specialization and Fee Dependence

We investigate whether the relation between auditor tenure and audit quality is conditional on auditor specialization and fee dependence. Although prior studies have investigated the relation between extended auditor-client tenure and audit quality, none has examined how this relation is jointly influenced by both auditor specialization and fee dependence. Our main analyses, using accrual quality as a measure of audit quality, show that firms audited by specialists (vs. non-specialists) have relatively higher audit quality with extended auditor tenure, and that this relation is negatively moderated by auditors’ fee dependence on clients. These results are robust to sensitivity tests, and alternative proxies for audit quality such as the issuance of going concern opinions and the market’s response to quarterly earnings surprises.

Activity of birds in the Western Hutt Hills, New Zealand

This paper describes the activity of garden, bush and riverine birds in the Western Hutt hills, 1981-92. The area is 15 km north of Wellington, 7 ! an north of the Hutt River estuary, and 15 ! an south of Pauatahanui Inlet, Porirua Harbour, on the southwest coast of the North Island. Observation is based on 35 years' residence and >12 500 10-min counts conducted between 1981 and 1992. Species first seen each day are distinguished from those first heard. Whenever possible the birds' food was recorded. The western hills have fewer native passerines than similar habitat on the eastern hills. Several species increased or decreased during the study. Some apparent decline was attributed to the author's hearing loss. Wind reduced bird detection. Nectar of New Zealand flax (Phormium spp.) was eaten by silvereyes (Zosterops lateralis), tui (Prosthemadera novaeseelandiae) and starlings (Sturnus vulgaris) at different times. In the study area there were about 0.9 cats (Felis catus) per household, a potential predator on birds. Gibb, J.A. 2000. Bird activity in the Western Hutt Hills, Wellington, New Zealand.

Estimation of noisy signals using time-invariant wavelet packets

Time-invariance plays a key role in many applications (e.g. signal reconstruction, identification, classification). Orthonormal wavelet and wavelet packet representations are known to be time-variant. We propose an extended wavelet packet decomposition, establish its time-invariance and give an efficient implementation. Some illustrating examples are also provided. <<ETX>>
