Radiation hydrodynamic simulations of line-driven disk winds for ultra-fast outflows
Authors: Nomura Mariko , Ohsuga Ken , Takahashi Hiroyuki R. , Wada Keiichi , Yoshida Tessei 
Published: January 2016

Abstract
Using two-dimensional radiation hydrodynamic simulations, we investigate the origin of the ultra-fast outflows (UFOs) that are often observed in luminous active galactic nuclei (AGNs). We found that the radiation force due to the spectral lines generates strong winds (line-driven disk winds) that are launched from the inner region of accretion disks (∼30 Schwarzschild radii). A wide range of black hole masses (MBH) and Eddington ratios (ε) was investigated to study the conditions causing the line-driven winds. For MBH = 106–109 M⊙ and ε = 0.1–0.7, funnel-shaped disk winds appear, in which dense matter is accelerated outward with an opening angle of 70°–80° and with 10% of the speed of light. If we observe the wind along its direction, the velocity, the column density, and the ionization state are consistent with those of the observed UFOs. As long as obscuration by the torus does not affect the observation of X-ray bands, the UFOs could be statistically observed in about 13%–28% of the luminous AGNs, which is not inconsistent with the observed ratio (∼40%). We also found that the results are insensitive to the X-ray luminosity and the density of the disk surface. Thus, we can conclude that UFOs could exist in any luminous AGNs, such as narrow-line Seyfert 1s and quasars with ε &gt; 0.1, with which fast line-driven winds are associated.
A systematic study of evolved supernova remnants in the large and small Magellanic Clouds with Suzaku

Abstract
Identifying the origin type (i.e., Type Ia or core-collapse) of supernova remnants (SNRs) is crucial to determining the rates of supernova (SN) explosions in a galaxy, which is a key to understanding its recent chemical evolution. However, evolved SNRs in the so-called Sedov phase are dominated by the swept-up interstellar medium (ISM), making it difficult to determine their ejecta composition and thus SN type. Here we present a systematic X-ray study of nine evolved SNRs in the Magellanic Clouds, DEM L238, DEM L249, 0534−69.9, 0548−70.4, B0532−71.0, B0532−67.5, 0103−72.6, 0049−73.6, and 0104−72.3, using archival data of the Suzaku satellite. Although Suzaku does not spatially resolve the SN ejecta from the swept-up ISM due to the limited angular resolution, its excellent energy resolution has enabled clear separation of emission lines in the soft X-ray band. This leads to the finding that the “spatially integrated” spectra of the evolved (∼104 yr) SNRs are still significantly contributed by emission from the ejecta at energies around 1 keV. The Fe/Ne mass ratios, determined mainly from the well-resolved Fe L-shell and Ne K-shell lines, clearly divide the observed SNRs into the Type Ia and core-collapse groups, confirming some previous typing made by Chandra observations that had utilized its extremely high angular resolution. This demonstrates that spatially integrated X-ray spectra of old SNRs can also be used to discriminate their progenitor type, which would be helpful for future systematic studies of extragalactic SNRs with ASTRO-H and beyond.

Authors: Kucherov Dmitry , Samokish Violetta 
Published: January 2016

Purpose
– This paper aims to assess the value of the employer brand through employer brand equity.

Design/methodology/approach
– Based on the model of employer brand equity by B. Minchington, the core employer brand assets (employer brand awareness, associations, loyalty, perceived employment experience) for three large companies are measured and the total employer brand equity strength is evaluated.

Findings
– The paper demonstrates a quantitative approach to employer brand evaluation. It takes into account the core target groups of the employer brand and could be the integrated tool for the assessment of the employer brand equity strength and its separate assets.

Practical implications
– In the paper, the universal formula for total employer brand strength evaluation is proposed. It provides evidence that employer brand needs to be measured systematically and depending on the value of its particular assets different employer brand activities should be intervened.

Originality/value
– The value of this paper is to provide the human resource team with a holistic set of tools for employer brand measurement to comprehend the competitive position of the company as an employer on the labor market.

Four important purpose areas represent opportunities for HR leaders to add value: create an innovative organization; create a technology leader; support the environment; and confront globalization.

Design/methodology/approach
– The paper represents the typical HR strategy and then provides an update to address 12 forces that are significantly influencing the success of organizations. Next, the paper focuses on four areas for human capital strategy that represents non-traditional areas.

Originality/value
– Expanding the typical human capital strategy to non-traditional areas provides a great opportunity to add value to the organization.
Professional attributes of the emerging academic dietetic educator workforce in Australia
Authors: Morgan Kate , Hughes Roger 
Published: January 2016

AbstractAimTo describe the size and demographic, education, experience and practice attributes of the core academic dietetic educator (ADEd) workforce in Australia.MethodsA self‐administered, cross‐sectional survey was electronically distributed to ADEds at 18 Australian universities offering dietetic programs. Data from survey responses were collated and descriptively analysed.ResultsFrom a total sample frame of 147 ADEds identified by websites, responses were received from 91 eligible ADEds (response rate = 62%), with at least one participant from each university offering a dietetics program in Australia. The sample was not representative of more senior ADEds, and therefore the core ADEd workforce. Rather, the sample was typically female aged 30–39 years with a Lecturer level, full‐time appointment who cited clinical dietetics as their main area of practice specialisation. Around half of the sample had yet to complete a PhD and had five years or less of experience working as a dietetic educator or a dietetic researcher.ConclusionsThe findings were limited to emerging ADEds due to the non‐participation and underrepresentation of more credentialed ADEds. The sample was relatively young and inexperienced in dietetic education and research. This may reflect the rapid expansion of dietetic education programs in Australia over the past decade and limited workforce surge capacity. Nevertheless the data reflect a small workforce group with the capacity to significantly influence future dietetic practitioners. Ongoing research and workforce development strategies are required to support the dietetic educator workforce and further enhance dietetic workforce preparation in Australia.

AbstractThe research studies the ultrastructure effect on texture of crisp grass carp (CGC) and grass carp (GC) fillets inducing heating for 15, 25, and 40 min with boiling water. After heating, the hardness, fracturability, springiness, chewiness, resilience, and cohesiveness of CGC were higher than that of raw CGC, whereas the all textural characteristics of heating GC were lower obviously than that of raw GC. The hardness, fracturability, springiness, chewiness, resilience, and cohesiveness of CGC for heating 15 min were higher by 6.3%, 9.0%, 27.0%, 71.8%, 9.4%, and 23.9%, respectively, than that of raw CGC (RCGC). The hardness increasing of CGC flesh with the extension of heating time related closely to more coagulating connective tissue in interstitial spaces, especially relating to smaller muscle fiber diameter and denser muscle fiber density. The more and larger spaces between fiber and fiber with the extension of heating time results in the decrease of cohesiveness and resilience of CGC flesh. For chewiness, the stronger chewiness of cooked CGC associated with more detachment of myofiber–myocommata and fiber–fiber. Overall, the results show that the changes of texture characteristics of CGC fillet with extension of heating time correlates positively with the ultrastructure.
Sperm chromatin structure assay in prediction of in vitro fertilization outcome
Authors: Oleszczuk K. , Giwercman A. , Bungum M. 
Published: January 2016

SummarySperm DNA fragmentation index (DFI) assessed by sperm chromatin structure assay is a valuable tool for prediction of fertility in vivo. Previous studies on DFI as predictor of in vitro fertilization (IVF) outcome, based on relatively small materials, gave contradictory results. The present study examines, in a large cohort, the association between sperm DFI and the outcome of IVF/ICSI procedure. The study is based on 1633 IVF or ICSI cycles performed at the Reproductive Medicine Centre, Skåne University Hospital, Malmö, Sweden, between May 2007 and March 2013. DFI values were categorized into four intervals: DFI ≤ 10% (reference group), 10% < DFI ≤ 20%, 20% < DFI ≤ 30%, DFI > 30%. For the three latter intervals, the following outcomes of IVF/ICSI procedures were analyzed in relation to the reference group: fertilization, good quality embryo, pregnancy, miscarriage, and live births. In the standard IVF group, a significant negative association between DFI and fertilization rate was found. When calculated per ovum pick‐up (OPU) Odds Ratios (ORs) for at least one good quality embryo (GQE) were significantly lower in the standard IVF group if DFI > 20%. OR for live birth calculated per OPU was significantly lower in standard IVF group if DFI > 20% (OR 0.61; 95% CI: 0.38–0.97; p = 0.04). No such associations were seen in the ICSI group. OR for live birth by ICSI compared to IVF were statistically significantly higher for DFI > 20% (OR 1.7; 95% CI: 1.0–2.9; p = 0.05). OR for miscarriage was significantly increased for DFI > 40% (OR 3.8; 95% CI: 1.2–12; p = 0.02). The results suggest that ICSI might be a preferred method of in vitro treatment in cases with high DFI. Efforts should be made to find options for pharmacologically induced reduction of DFI. The study was based on retrospectively collected data and prospective studies confirming the superiority of ICSI in cases with high DFI are warranted.

SummaryCryptorchidism, a common anomaly of the male genitalia, affects 2–4% of male infants. The post‐fertilization effects of unilateral cryptorchidism model in the rat and the effects of antioxidant treatment were investigated. Six‐week‐old male Wistar rats were randomly separated into four groups. Unilateral cryptorchidism was induced in the right testis of three groups. One group was treated with saline intraperitoneally (i.p.) (Crypto), one group was treated with taurine (500 mg/kg, i.p.; Tau), and another group was treated with sivelestat (15 mg/kg i.p.; Siv). The control group was treated with saline i.p. The treatment was daily for 8 weeks. Five days before sacrifice, mating studies were performed. Body, testicular, and epididymal weights were recorded. Malondialdehyde (MDA) levels in the seminal vesicular fluid (SVF) were measured. Testicular levels of MDA and 8‐hydroxy‐2′‐deoxyguanosine (8‐OHdG) were determined bilaterally. TUNEL assay was used to examine DNA fragmentation bilaterally. Histological examination and the Johnsen score were used to evaluate morphological testicular alterations. The Crypto group demonstrated significantly lower right testicular and epididymal weights, significantly increased SVF‐MDA levels, testicular MDA and 8‐OHdG levels, and the apoptotic score bilaterally compared to the controls. Furthermore, histological evaluation revealed significantly reduced spermatogenesis and mild injury to the cryptorchid testes compared to the control. Treatment with both taurine and sivelestat significantly reduced SVF‐MDA levels, testicular MDA, 8‐OHdG, and apoptosis bilaterally compared to the Crypto group. Antioxidant treatment was unable to ameliorate spermatogenesis. Newborns delivered by females that mated with Crypto‐males had significantly lower body weight compared with the respective animals from the control, Tau and Siv groups. The present study demonstrated that unilateral cryptorchidism‐induced testicular damage can significantly affect the contralateral testis as well having further deleterious post‐fertilization effect on the development of newborns. Treatment with antioxidants can partially improve the testicular damage bilaterally with beneficial effects for the newborns.
Generalised Smooth Tests of Goodness of Fit Utilising L‐moments
Authors: Thas O. , Rayner J.C.W. , De Neve J. 
Published: January 2016

SummaryIn this paper we present a semiparametric test of goodness of fit which is based on the method of L‐moments for the estimation of the nuisance parameters. This test is particularly useful for any distribution that has a convenient expression for its quantile function. The test proceeds by investigating equality of the first few L‐moments of the true and the hypothesised distributions. We provide details and undertake simulation studies for the logistic and the generalised Pareto distributions. Although for some distributions the method of L‐moments estimator is less efficient than the maximum likelihood estimator, the former method has the advantage that it may be used in semiparametric settings and that it requires weaker existence conditions. The new test is often more powerful than competitor tests for goodness of fit of the logistic and generalised Pareto distributions.
Model Assessment in Dynamic Treatment Regimen Estimation via Double Robustness
Authors: Wallace Michael P. , Moodie Erica E. M. , Stephens David A. 
Published: January 2016

Summary
Dynamic treatment regimens (DTRs) recommend treatments based on evolving subject-level data. The optimal DTR is that which maximizes expected patient outcome and as such its identification is of primary interest in the personalized medicine setting. When analyzing data from observational studies using semi-parametric approaches, there are two primary components which can be modeled: the expected level of treatment and the expected outcome for a patient given their other covariates. In an effort to offer greater flexibility, the so-called doubly robust methods have been developed which offer consistent parameter estimators as long as at least one of these two models is correctly specified. However, in practice it can be difficult to be confident if this is the case. Using G-estimation as our example method, we demonstrate how the property of double robustness itself can be used to provide evidence that a specified model is or is not correct. This approach is illustrated through simulation studies as well as data from the Multicenter AIDS Cohort Study.
Addressing Issues Associated with Evaluating Prediction Models for Survival Endpoints Based on the Concordance Statistic
Authors: Wang Ming , Long Qi 
Published: January 2016

SummaryPrediction models for disease risk and prognosis play an important role in biomedical research, and evaluating their predictive accuracy in the presence of censored data is of substantial interest. The standard concordance (c) statistic has been extended to provide a summary measure of predictive accuracy for survival models. Motivated by a prostate cancer study, we address several issues associated with evaluating survival prediction models based on statistic with a focus on estimators using the technique of inverse probability of censoring weighting (IPCW). Compared to the existing work, we provide complete results on the asymptotic properties of the IPCW estimators under the assumption of coarsening at random (CAR), and propose a sensitivity analysis under the mechanism of noncoarsening at random (NCAR). In addition, we extend the IPCW approach as well as the sensitivity analysis to high-dimensional settings. The predictive accuracy of prediction models for cancer recurrence after prostatectomy is assessed by applying the proposed approaches. We find that the estimated predictive accuracy for the models in consideration is sensitive to NCAR assumption, and thus identify the best predictive model. Finally, we further evaluate the performance of the proposed methods in both settings of low-dimensional and high-dimensional data under CAR and NCAR through simulations.

SummaryThis book examines the role of course management systems (cmss) in higher education. Some chapters consider broader issues such as trends, cms governance, and evaluation; others examine the implementation of pedagogical initiatives using cmss. The case studies in this second group feature initiatives by educators who show more or less familiarity with their cmss. A recurring theme is the “eco‐systemic” quality of cms systems, their institutions, and institutional stakeholders. This book would be of interest to university administrators, information systems professionals, and academics. If the content of this book is likely to be relevant to you, I advise that you will probably find only parts of it of interest or use.Sara Hammer
