The Luminosity Function of Early-Type Field Galaxies at z ≈ 0.75

We measure the luminosity function of morphologically selected E/S0 galaxies from z = 0.5 to 1.0 using deep high-resolution Advanced Camera for Surveys (ACS) imaging data. Our analysis covers an area of 48 arcmin2 (8 times the area of the Hubble Deep Field North) and extends 2 mag deeper (I ∼ 24 mag) than was possible in the Deep Groth Strip Survey (DGSS). Our fields were observed as part of the ACS Guaranteed Time Observations. At 0.5 < z < 0.75, we find M - 5 log h0.7 = -21.1 ± 0.3 and α = -0.53 ± 0.2, and at 0.75 < z < 1.0, we find M - 5 log h0.7 = -21.4 ± 0.2, consistent with 0.3 mag of luminosity evolution (across our two redshift intervals). These luminosity functions are similar in both shape and number density to the luminosity function using morphological selection (e.g., DGSS), but are much steeper than the luminosity functions of samples selected using morphological proxies such as the color or spectral energy distribution (e.g., CFRS, CADIS, or COMBO-17). The difference is due to the "blue," (U - V)0 < 1.7, E/S0 galaxies, which make up to ∼30% of the sample at all magnitudes and an increasing proportion of faint galaxies. We thereby demonstrate the need for both morphological and structural information to constrain the evolution of galaxies. We find that the blue E/S0 galaxies have the same average sizes and Sersic parameters as the "red," (U - V)0 > 1.7, E/S0 galaxies at brighter luminosities (MB < -20.1), but are increasingly different at fainter magnitudes, where blue galaxies are both smaller and have lower Sersic parameters. We find differences in both the size-magnitude relation and the photometric plane offset for red and blue E/S0s, although neither red nor blue galaxies give a good fit to the size-magnitude relation. Fits of the colors to stellar population models suggest that most E/S0 galaxies have short star formation timescales (τ < 1 Gyr), and that galaxies have formed at an increasing rate from z ∼ 8 until z ∼ 2, after which there has been a gradual decline.
Experimental probe of minority carrier velocity profile

We experimentally investigate the details of the minority electron transport across the base of a GaAs heterojunction bipolar transistor (HBT). A stepwise doping change in the base layer is employed to locally accelerate the electrons and enhance the dc current gain. The position of the step change is varied to probe the electron velocity across the base layer in multiple sample sets with different base thicknesses. Positioning the doping change within 200 /spl Aring/ of the collector provides the largest velocity increase (/spl sim/15%), independent of base thickness. This indicates that the electrons are moving slower as they approach the collector, an observation which sharply contrasts with the conventional quasi-ballistic drift-diffusion models of base transport that predict the highest electron velocities are reached near the collector.
Cost‐penalized estimation and prediction evaluation for split‐plot designs

Comparisons between different designs have traditionally focused on balancing the quality of estimation or prediction relative to the overall size of the design. For split‐plot designs with two levels of randomization, the total number of observations may not accurately summarize the true cost of the experiment, because different costs are likely associated with setting up the whole and subplot levels. In this paper, we present several flexible measures for design assessment based on D‐, G‐ and V‐optimality criteria that take into account potentially different cost structures for the split‐plot designs. The new measures are illustrated with two examples: a 23 factorial experiment for first‐order models, where all possible designs are considered, and selective designs for a three‐factor second‐order model.

Performance management fairness and burnout: implications for organizational citizenship behaviors

ABSTRACT Drawing upon organizational justice theory, we examine how perceptions of performance management fairness affect burnout and organizational citizenship behaviors among academic employees. Data from 532 academic employees from a university in Flanders (Belgium) were analyzed using structural equation modeling. Academic employees experience less burnout when performance management fairness is perceived as high. Performance management distributive and interactional fairness increase organizational citizenship behaviors by reducing burnout and supporting partial mediation. Higher education institutions should carefully design and implement performance management systems with fair outcomes, procedures and treatment of employees. Our findings stress the importance of fair performance management systems and offer new insights on how these systems affect employee outcomes.
Students in Faith-Based Doctoral Psychology Programs: Religious/Spiritual Struggles Moderate the Effect of Distress from Clinical Work on Negative Affect

Objective: The present study assessed 96 doctoral psychology students at APA-accredited faith-based institutions to further understand the relationships between distress from clinical work, religious and spiritual (r/s) struggles, and negative affect. Based on past research it was hypothesized that distress from clinical work would predict heightened r/s struggles and negative affect. Furthermore, we hypothesized r/s struggles would moderate the effect between distress from clinical work and negative affect. Findings were significant, and demonstrated that our population experienced heightened levels of distress from clinical work, r/s struggles, and negative affect compared to the normed populations. The relationships between distress from clinical work and r/s struggles as well as distress from clinical work and negative affect were significant. Religious and spiritual struggles further moderated the relationship in that those experiencing r/s struggles alongside distress from clinical work demonstrated a stronger relationship between distress from clinical work and negative affect. A more comprehensive discussion regarding these findings as well as the limitations, areas of future research, and implications for training are included in the following.
Optimal Security Design and Dynamic Capital Structure in a Continuous‐Time Agency Model

We derive the optimal dynamic contract in a continuous‐time principal‐agent setting, and implement it with a capital structure (credit line, long‐term debt, and equity) over which the agent controls the payout policy. While the project's volatility and liquidation cost have little impact on the firm's total debt capacity, they increase the use of credit versus debt. Leverage is nonstationary, and declines with past profitability. The firm may hold a compensating cash balance while borrowing (at a higher rate) through the credit line. Surprisingly, the usual conflicts between debt and equity (asset substitution, strategic default) need not arise.
The opportunity for sexual selection: not mismeasured, just misunderstood

Evolutionary biologists have developed several indices, such as selection gradients (β) and the opportunity for sexual selection (Is), to quantify the actual and/or potential strength of sexual selection acting in natural or experimental populations. In a recent paper, Klug et al. (J. Evol. Biol.23, 2010, 447) contend that selection gradients are the only legitimate metric for quantifying sexual selection. They argue that Is and similar mating‐system‐based metrics provide unpredictable results, which may be uncorrelated with selection acting on a trait, and should therefore be abandoned. We find this view short‐sighted and argue that the choice of metric should be governed by the research question at hand. We describe insights that measures such as the opportunity for selection can provide and also argue that Klug et al. have overstated the problems with this approach while glossing over similar issues with the interpretation of selection gradients. While no metric perfectly characterizes sexual selection in all circumstances, thoughtful application of existing measures has been and continues to be informative in evolutionary studies.
Gaze vs. Mouse: A Fast and Accurate Gaze-Only Click Alternative

Eye gaze tracking is a promising input method which is gradually finding its way into the mainstream. An obvious question to arise is whether it can be used for point-and-click tasks, as an alternative for mouse or touch. Pointing with gaze is both fast and natural, although its accuracy is limited. There are still technical challenges with gaze tracking, as well as inherent physiological limitations. Furthermore, providing an alternative to clicking is challenging. We are considering use cases where input based purely on gaze is desired, and the click targets are discrete user interface (UI) elements which are too small to be reliably resolved by gaze alone, e.g., links in hypertext. We present Actigaze, a new gaze-only click alternative which is fast and accurate for this scenario. A clickable user interface element is selected by dwelling on one of a set of confirm buttons, based on two main design contributions: First, the confirm buttons stay on fixed positions with easily distinguishable visual identifiers such as colors, enabling procedural learning of the confirm button position. Secondly, UI elements are associated with confirm buttons through the visual identifiers in a way which minimizes the likelihood of inadvertent clicks. We evaluate two variants of the proposed click alternative, comparing them against the mouse and another gaze-only click alternative.
Temporal reflexivity in journalism studies: Making sense of change in a more timely fashion

Journalism studies is a relatively young field trying to make sense of a relatively fast-moving scholarly object – news. The matter of time is emerging as a particularly vexing challenge: When so much seems to be changing, and so quickly, how are journalism studies researchers to discern meaningful developments as opposed to short-term ephemera? This essay argues for ‘temporal reflexivity’, a way of fostering critical judgment about whether some phenomenon is indeed a break from what came before, a continuation of what has existed, or some middle-ground mutation. Such thinking reveals how temporality is embedded within journalism studies, driving assumptions and incentives about how and what to research – as well as what not to research. In particular, we apply the lens of temporal reflexivity to discuss issues of time and attention across three key areas of concern for journalism studies’ development as a field: first, the need for an analytical approach that balances change and stasis; second, the need to address issues of scale in which it is difficult to discern passing fads from deeper shifts that may lead to new institutional forms; and third, the need to understand the complicated and circular role of journalism education, both in reinforcing discourses of ‘crisis’ and ‘innovation’ and in lending stability to the boundaries of journalism as professionalized practice. In all, this essay opens up ways of considering the taken-for-granted temporal implications of research questions and pedagogical practices in journalism studies.
BLAME ATTRIBUTION IN RAPE CRIMES: THE EFFECTS OF WILLING SUBSTANCE USE, RACE, AND RAPE MYTH ACCEPTANCE

Rape is a highly prevalent crime, and it is one of the most severe traumatic events experienced by women. Previous researchers have found that, unlike other crimes, blame attribution in rape cases is inconsistent and influenced by many external elements (Bieneck & Krahe, 2011; Grubb & Turner, 2012; Masser, Lee, & McKimmie, 2010; Stewart & Jacquin, 2010). In this study, the influence of willing substance use and race on attribution of blame from a sample of 316 undergraduate students attending a large, Southeastern, public, urban university was examined. More specifically, results from this investigation described how the type of substance (alcohol, marijuana, and heroin) consumed by female survivors and survivors’ race/ethnicity (Black, Hispanic, and White) influenced the level of blame assigned to them. Additionally, the researcher explored the interactive effect of the drug type and survivors’ race. The results of the analysis of variance (ANOVA) revealed that both survivors’ substance use and race significantly influenced blame attribution. Survivors who consumed alcohol prior to the assault were blamed more than survivors who used heroin or marijuana and survivors who did not consume any substances. Regarding the influence of survivors’ race/ethnicity, White female survivors were attributed significantly higher levels of blame than Black and Hispanic female survivors. In addition to the examined conditions of substance use and race/ethnicity, the results of this study indicated that observers’ demographic characteristics influenced blame attribution as well. Observers’ gender, race, and knowledge of a person who has survived rape were all significant factors effecting attribution of blame.

Oral Chinese Herbal Medicine Combined with Pharmacotherapy for Stable COPD: A Systematic Review of Effect on BODE Index and Six Minute Walk Test

This systematic review evaluated the effects of Chinese herbal medicine (CHM) plus routine pharmacotherapy (RP) on the objective outcome measures BODE index, 6-minute walk test (6MWT), and 6-minute walk distance (6MWD) in individuals with stable chronic obstructive pulmonary disease (COPD). Searches were conducted of six English and Chinese databases (PubMed, EMBASE, CENTRAL, CINAHL, CNKI and CQVIP) from their inceptions until 18th November 2013 for randomized controlled trials involving oral administration of CHM plus RP compared to the same RP, with BODE Index and/or 6MWT/D as outcomes. Twenty-five studies were identified. BODE Index was used in nine studies and 6MWT/D was used in 22 studies. Methodological quality was assessed using the Cochrane Risk of Bias tool. Weaknesses were identified in most studies. Six studies were judged as ‘low’ risk of bias for randomisation sequence generation. Twenty-two studies involving 1,834 participants were included in the meta-analyses. The main meta-analysis results showed relative benefits for BODE Index in nine studies (mean difference [MD] −0.71, 95% confidence interval [CI] −0.94, −0.47) and 6MWT/D in 17 studies (MD 54.61 meters, 95%CI 33.30, 75.92) in favour of the CHM plus RP groups. The principal plants used were Astragalus membranaceus, Panax ginseng and Cordyceps sinensis. A. membranaceus was used in combination with other herbs in 18 formulae in 16 studies. Detailed sub-group and sensitivity analyses were conducted. Clinically meaningful benefits for BODE Index and 6MWT were found in multiple studies. These therapeutic effects were promising but need to be interpreted with caution due to variations in the CHMs and RPs used and methodological weakness in the studies. These issues should be addressed in future trials.
Mapping adolescent brain change reveals dynamic wave of accelerated gray matter loss in very early-onset schizophrenia

Neurodevelopmental models for the pathology of schizophrenia propose both polygenetic and environmental risks, as well as early (pre/perinatal) and late (usually adolescent) developmental brain abnormalities. With the use of brain mapping algorithms, we detected striking anatomical profiles of accelerated gray matter loss in very early-onset schizophrenia; surprisingly, deficits moved in a dynamic pattern, enveloping increasing amounts of cortex throughout adolescence. Early-onset patients were rescanned prospectively with MRI, at 2-year intervals at three time points, to uncover the dynamics and timing of disease progression during adolescence. The earliest deficits were found in parietal brain regions, supporting visuospatial and associative thinking, where adult deficits are known to be mediated by environmental (nongenetic) factors. Over 5 years, these deficits progressed anteriorly into temporal lobes, engulfing sensorimotor and dorsolateral prefrontal cortices, and frontal eye fields. These emerging patterns correlated with psychotic symptom severity and mirrored the neuromotor, auditory, visual search, and frontal executive impairments in the disease. In temporal regions, gray matter loss was completely absent early in the disease but became pervasive later. Only the latest changes included dorsolateral prefrontal cortex and superior temporal gyri, deficit regions found consistently in adult studies. These emerging dynamic patterns were (i) controlled for medication and IQ effects, (ii) replicated in independent groups of males and females, and (iii) charted in individuals and groups. The resulting mapping strategy reveals a shifting pattern of tissue loss in schizophrenia. Aspects of the anatomy and dynamics of disease are uncovered, in a changing profile that implicates genetic and nongenetic patterns of deficits.
IFNs Modify the Proteome of Legionella-Containing Vacuoles and Restrict Infection Via IRG1-Derived Itaconic Acid

Macrophages can be niches for bacterial pathogens or antibacterial effector cells depending on the pathogen and signals from the immune system. Here we show that type I and II IFNs are master regulators of gene expression during Legionella pneumophila infection, and activators of an alveolar macrophage-intrinsic immune response that restricts bacterial growth during pneumonia. Quantitative mass spectrometry revealed that both IFNs substantially modify Legionella-containing vacuoles, and comparative analyses reveal distinct subsets of transcriptionally and spatially IFN-regulated proteins. Immune-responsive gene (IRG)1 is induced by IFNs in mitochondria that closely associate with Legionella-containing vacuoles, and mediates production of itaconic acid. This metabolite is bactericidal against intravacuolar L. pneumophila as well as extracellular multidrug-resistant Gram-positive and -negative bacteria. Our study explores the overall role IFNs play in inducing substantial remodeling of bacterial vacuoles and in stimulating production of IRG1-derived itaconic acid which targets intravacuolar pathogens. IRG1 or its product itaconic acid might be therapeutically targetable to fight intracellular and drug-resistant bacteria.
THE EFFECT OF MULTIMEDIA ANNOTATION MODES ON L2 VOCABULARY ACQUISITION: A COMPARATIVE STUDY

One aspect of second language teaching via multimedia to have received attention over the past few years is the impact of glossing individual vocabulary words through different modalities. This study examines which of the image modalities--dynamic video or still picture--is more effective in aiding vocabulary acquisition. The participants, 30 ESL students, were introduced to a hypermedia-learning program, designed by the researcher for reading comprehension. The program provides users reading a narrative English text with a variety of glosses or annotations for words in the form of printed text, graphics, video, and sound, all of which are intended to aid in the understanding and learning of unknown words. A within-subject design was used in this study with 30 participants being measured under three conditions: printed text definition alone, printed text definition coupled with still pictures, and printed text definition coupled with video clips. In order to assess the efficacy of each mode, a vocabulary test was designed and administered to participants after they had read the English narrative. Two types of tests were administered: recognition and production. In addition, a face-to-face interview was conducted, and questionnaires were distributed. Results of the both tests were analyzed using analysis of variance procedures. The investigation has yielded the conclusion that a video clip is more effective in teaching unknown vocabulary words than a still picture. Among the suggested factors that explain such a result are that video better builds a mental image, better creates curiosity leading to increased concentration, and embodies an advantageous combination of modalities (vivid or dynamic image, sound, and printed text).
ENDOGLIN Is Dispensable for Vasculogenesis, but Required for Vascular Endothelial Growth Factor-Induced Angiogenesis

ENDOGLIN (ENG) is a co-receptor for transforming growth factor-β (TGF-β) family members that is highly expressed in endothelial cells and has a critical function in the development of the vascular system. Mutations in Eng are associated with the vascular disease known as hereditary hemorrhagic telangiectasia type l. Using mouse embryonic stem cells we observed that angiogenic factors, including vascular endothelial growth factor (VEGF), induce vasculogenesis in embryoid bodies even when Eng deficient cells or cells depleted of Eng using shRNA are used. However, ENG is required for the stem cell-derived endothelial cells to organize effectively into tubular structures. Consistent with this finding, fetal metatarsals isolated from E17.5 Eng heterozygous mouse embryos showed reduced VEGF-induced vascular network formation. Moreover, shRNA-mediated depletion and pharmacological inhibition of ENG in human umbilical vein cells mitigated VEGF-induced angiogenesis. In summary, we demonstrate that ENG is required for efficient VEGF-induced angiogenesis.
The spectral norm error of the naive Nystrom extension

The naive Nystrom extension forms a low-rank approximation to a positive-semidefinite matrix by uniformly randomly sampling from its columns. This paper provides the first relative-error bound on the spectral norm error incurred in this process. This bound follows from a natural connection between the Nystrom extension and the column subset selection problem. The main tool is a matrix Chernoff bound for sampling without replacement.
