When should we treat galaxies as isolated

Traditionally, secular evolution is defined as evolution of systems where the internal growth of structure and instabilities dominates the growth via external drivers (e.g. accretion and mergers). Most study has focused on “isolated” galaxies, where seed asymmetries may represent realistic cosmological substructure, but su bsequent evolution ignores galaxy growth and interactions. Large-scale modes in the disk then grow on a timescale of order a disk rotation period (� 0: 1 1 Gyr). If, however, galaxies evolve cosmologically on a shorter timescale, then it may not be appropriate to consider them “isolated. ” We outline simple scalings to ask whether, under realistic conditions, the timesc ale for secular evolution is shorter than the timescale for cosmological accretion and mergers. We show that this is the case in a relatively narrow, but important range of perturbation amp litudes corresponding to substructure or mode/bar fractional amplitudes � � 0: 01 0: 1, the range of most interest for observed strong bars and most pseudobulges. At smaller amplitudes � � 0: 1, systems are not isolated: typical disks will grow by accretion at a comparable level over even a single dynamical time. At larger amplitudes � � 0: 1, the evolution is no longer secular; the direct gravitatio nal evolution of the seed substructure swamps the internal disk res ponse. We derive criteria for when disks can be well-approximated as “isolated” as a function of mass, redshift, and disk stability. The relevant parameter space shrinks at higher mass, hi gher disk stability, and higher- z as accretion rates increase. The cosmological rate of galaxy e volution also defines a maximum bar/mode lifetime of practical interest, of � 0: 1t Hubble(z). Longer-lived modes will encounter cosmological effects and will de-couple from their drivers (if they are driven).
Towards Afrocentric Counternarratives of Race and Racism in Australia

This article looks at the everyday life and realities of some of Australia’s most recent immigrant communities, by shedding light on the experiences of black Africans in Queensland. Particularly, this article examines the experiences of black African migrants and refugees living in South East Queensland, to better understand how race, skin colour and immigration status interact to shape their everyday lives and social location in Australia. Data were collected from 30 participants using qualitative research methods. The theoretical approach employed synthesises concepts from identity, blackness, race and racism, whiteness and critical race theory. The subjective experiences of the participants interviewed indicate that skin colour still matters in determining life chances for black Africans in Australia. While the empirical focus is specific to Australia, this article contributes to the research literature in valuable ways, both from a theoretical perspective and in terms of a comparative contextualisation of racism. Introduction Queensland, the third most populous state in Australia, is home to many migrants and refugees. In more recent years, Queensland has accepted many black African migrants and refugees. Many of these Africans have come to build new lives, change their families’ circumstances and give new hope to their dreams (Jakubowicz, 2010; Udah, 2018). These African settler arrivals, though a very diverse group, add an important chapter to the history of immigration in Australia broadly and Queensland specifically. This article
Environmental effects on forage and longline fishery performance for albacore (Thunnus alalunga) in the American Samoa Exclusive Economic Zone

The South Equatorial Counter Current (SECC) strongly influences the American Samoa Exclusive Economic Zone (EEZ) and changes strength on a seasonal and ENSO cycle. A strong SECC is associated with a predominantly anticyclonic eddy field as well as increased micronekton biomass and catchper-unit-effort (CPUE) for albacore tuna, the economically important target species of the local longline fishery. A strong SECC carries chlorophyll arich waters from upwelling regions at the north coast of New Guinea towards the EEZ, most likely resulting in the observed increase in micronekton biomass, forage for albacore. Relatively stable anticyclonic eddies show a further increase in micronekton biomass, apparently advected from neighboring SECC waters. The presence of forage presumably concentrates albacore, thus resulting in the observed increase in CPUE. High shear regions of neither anticyclonic nor cyclonic eddies correlate with increased micronekton biomass. Areas characterized by South Equatorial Current (SEC) waters correspond to areas with the lowest micronekton biomass and the highest number of aggregative structures, which are most likely small pelagic fish shoals. Micronekton composition in SEC waters differs from that in the SECC.
Iron and zinc retention in common beans (Phaseolus vulgaris L.) after home cooking

Background According to the World Health Organization (WHO), iron, iodine, and Vitamin A deficiencies are the most common forms of malnutrition, leading to severe public health consequences. The importance of iron and zinc in human nutrition and the number of children found to be deficient in these nutrients make further studies on retention in cooked grains and cooked bean broth important. Objectives This work aimed to evaluate iron and zinc retention in six common bean (Phaseolus vulgaris L.) cultivars under the following conditions: raw beans, regular pot cooking, pressure cooking, with and without previous water soaking, and broth. Design Determination of iron and zinc content in the raw, cooked bean grains and broth samples was carried out by Inductively Coupled Plasma (ICP) Optical Emission Spectrometry (Spectro Analytical Instrument – Spectroflame P). All experiments and analyses were carried out in triplicate. Results Overall, regardless of the cooking method, with or without previous water soaking, the highest zinc concentration was found in the cooked bean grains. However, pressure cooking and previous water soaking diminished iron retention in the cooked grains, while increasing it in the bean broth. Conclusion The common bean was confirmed to be an excellent source of iron and zinc for human consumption, and it was suggested that beans should be consumed in a combined form, i.e. grain with bean broth.
Platelet-based coding of depth maps for the transmission of multiview images

Emerging 3-D displays show several views of the scene simultaneously. A direct transmission of a selection of these views is impractical, because various types of displays support a different number of views and the decoder has to interpolate the intermediate views. The transmission of multiview image information can be simplified by only transmitting the texture data for the central view and a corresponding depth map. Additional to the coding of the texture data, this technique requires the efficient coding of depth maps. Since the depth map represents the scene geometry and thereby covers the 3-D perception of the scene, sharp edges corresponding to object boundaries, should be preserved. We propose an algorithm that models depth maps using piecewise-linear functions (platelets). To adapt to varying scene detail, we employ a quadtree decomposition that divides the image into blocks of variable size, each block being approximated by one platelet. In order to preserve sharp object boundaries, the support area of each platelet is adapted to the object boundary. The subdivision of the quadtree and the selection of the platelet type are optimized such that a global rate-distortion trade-off is realized. Experimental results show that the described method can improve the resulting picture quality after compression of depth maps by 1-3 dB when compared to a JPEG-2000 encoder.
Sensitivity of Dryline Convection Forecasts to Upstream Forecast Errors for Two Weakly Forced MPEX Cases

AbstractThe sensitivity of convective forecasts along the Texas dryline to upstream forecast fields at earlier lead times is evaluated for two consecutive days (27–28 May) characterized by no clear synoptic forcing for convection initiation (CI) during the 2013 Mesoscale Predictability Experiment (MPEX) by applying the ensemble-based sensitivity technique to convection-allowing WRF ensemble forecasts. For both cases, the members with stronger convection are characterized by higher water vapor just above the top of the boundary layer, which is associated with lower convective inhibition (CIN) at the time of CI. Forecast convection is sensitive to the lower-tropospheric water vapor and zonal wind at earlier lead times farther south along the dryline, such that increasing the water vapor and/or making the wind more easterly is associated with more convection. For 28 May, the water vapor along the dryline is also sensitive to the convection that occurs around 0600 UTC, which leads to cold pool–induced surface.
Survival and Physiologic Response of Common Amakihi and Japanese White-Eyes During Simulated Translocation

We evaluated the effects of three translocation trials on Common Amakihi (Hemignathus virens) and Japanese White-eyes (Zosterops japonicus). Trial 1 involved capturing birds, transporting them on rough roads for 4 hr followed by holding in an aviary for 48 hr without overnight thermal support prior to release, Trial 2 involved capture, then holding in an aviary for 48 hr with overnight thermal support followed by transport for 4 hr prior to release. Trial 3 and I were identical except that overnight thermal support was provided during trial 3. We monitored survival, food consumption, weight change, and fecal production during captivity as well as changes in hematocrit, estimated total solids, heterophil to lymphocyte ratios, plasma uric acid, and creatinine phosphokinase (CPK) at capture and release. Survival was significantly lower for Amakihi during trial 1 (no thermal support). Birds that died lost significantly more weight than those that survived. Regardless of trial, birds responded to translocation by a combination of weight loss, anemia, hypoproteinemia, and elevated heterophil to lymphocyte ratio, uric acid, and CPK levels. The first 24 hr of captivity posed the greatest risk to birds regardless of whether transport or holding occurred first. Food consumption, fecal production, and weight all decreased at night, and overnight thermal support during holding was critical if ambient temperatures dipped to freezing. We recommend that if small passerines are to be held for > 12 hr, they be monitored individually for weight loss, food consumption, and fecal production.
The impact of person-organization fit and leader-member exchange on withdrawal behaviors in Thailand

Purpose The purpose of this paper is to examine the impact of person-organization fit and leader-member exchange (LMX) on the withdrawal behaviors of Thai employees. Design/methodology/approach Self-report questionnaires were received from 300 employees working in one of the largest Thai public universities. Exploratory factor analysis was conducted, followed by confirmatory factor analysis. Structural equation model was then implemented to test the relationships among all variables. Findings The results showed negative relationships between person-organization fit and withdrawal behaviors, between LMX and withdrawal behaviors, and between person-organization fit and LMX and an intention to leave. However, only person-organization fit was statistically significant with withdrawal behaviors and an intention to leave. The progression model of withdrawal behaviors was also supported. Research limitations/implications The self-report questionnaires were the limitations of the study. Practical implications This study highlighted the importance of withdrawal behaviors and an intention to leave an organization which are costly behaviors. Person-organization fit should be emphasized at the recruitment and selection process, and coherent human resource practices should be used in an organization to possibly lessen these costly behaviors. Originality/value This study contributed to the knowledge of withdrawal behaviors, covering both least severe and more extreme behaviors. This study suggested that an organization should pay attention to these least severe withdrawal behaviors among employees, since these can lead to an extreme withdrawal behavior – i.e. an intention to leave an organization.
FDI And Economic Growth Relationship In Sub-Saharan Africa: Is The Domestic Financial System A Significant Intermediator?

This paper contributes to the literature on the effect of Foreign Direct Investment (FDI) on economic growth by examining the role of financial development as a source of absorptive capacity in the FDI-economic growth relationship in Sub-Saharan Africa (SSA). Using panel data econometric techniques and an unbalanced dataset of 1989-2013, we examine the independent effect of FDI on economic growth, as well as the impact of an interactive relationship between FDI and financial development on economic growth in SSA. We find that FDI does not directly lead to economic growth in SSA. However, the financial system through banking sector development enhances the effect of FDI on economic growth in the region. This finding is linked to the existence of a causal relationship between banking sector development and FDI, which is stronger in the low-income subsample relative to the middle-income subsample and the full SSA sample. We also estimate the threshold financial development levels essential for the expected FDI-economic growth effect to occur. Finally, the study recommends that strategies toward the attraction of foreign capital in SSA must be complemented by measures to develop the domestic financial system.
IMAGE RECOVERY USING FUNCTIONS OF BOUNDED VARIATION AND SOBOLEV SPACES OF NEGATIVE DIFFERENTIABILITY

In this work we wish to recover an unknown image from a blurry, or noisy-blurry version. We solve this inverse problem by energy minimization and regularization. We seek a solution of the form $u + v$, where $u$ is a function of bounded variation (cartoon component), while $v$ is an oscillatory component (texture), modeled by a Sobolev function with negative degree of differentiability. We give several results of existence and characterization of minimizers of the proposed optimization problem. Experimental results show that this cartoon + texture model better recovers textured details in natural images, by comparison with the more standard models where the unknown is restricted only to the space of functions of bounded variation.
Meta-Analysis to Assess the Quality of Warfarin Control in Atrial Fibrillation Patients in the United States

BACKGROUND: Atrial fibrillation (AF) affects a significant proportion of the American population and increases ischemic stroke risk by 4- to 5-fold. Oral vitamin K antagonists, such as warfarin, can significantly reduce this stroke risk but can be difficult to dose and monitor. Previous research on the effects of setting (e.g., randomized controlled trials, anticoagulation management by specialty clinics, and usual care by community physicians) on the proportion of time spent within therapeutic range for the international normalized ratio (INR) has not specifically examined anticoagulation in AF patients. OBJECTIVES: Use traditional meta-analytic and meta-regressive techniques to evaluate the effect of specialty clinic versus usual care by community physicians on anticoagulation control, measured as the proportion of time spent in therapeutic INR range, for AF patients that received warfarin anticoagulation in the United States. METHODS: Studies included in a previously published meta-analysis (van Walraven et al., 2006), which systematically searched reports between 1987 and 2005, were also screened for inclusion in our analysis. A subsequent systematic literature search of MEDLINE, EMBASE, and the Cochrane Central Register of Clinical Trials from January 2005 through February 2008 was conducted. Studies were included if they (a) contained at least 1 warfarin-treated group including more than 25 patients for whom INR control was monitored for at least 3 weeks; (b) included patients treated for AF in the United States; (c) used a patient-time approach (patient-year) to report outcomes; and (d) reported data on the proportion of time spent in traditional therapeutic INR ranges (i.e., a lower limit INR between 1.8 and 2.0 and an upper limit INR between 3.0 and 3.5. Studies with INR goals outside this range were excluded). The proportion of time spent within the therapeutic INR range for each study group was expressed as an incidence density using a person-time approach (in years). All studies were pooled using a random effects model and were weighted by the inverse of the variance of proportion of time spent in the therapeutic range. In order to determine how study setting influenced the proportion of time spent within a therapeutic INR range, both subgroup and meta-regression analyses were conducted. RESULTS: This analysis included 8 studies and a total of 14 unique warfarin-treated groups; 3 of the 8 studies and 4 of the warfarin groups were not included in the previous meta-analysis (van Walraven et al., 2006). Overall, patients spent a mean 55% (95% CI = 51%-58%) of their time in the therapeutic INR range. Meta-regression suggested that AF patients treated in a community usual care setting compared with an anticoagulation clinic spent 11% (95% CI = 2%-20%, n = 6 studies with 9 study groups) less time in range. CONCLUSIONS: In the United States, AF patients spend only about one-half the time within therapeutic INR. Anticoagulation clinic services are associated with somewhat better INR control compared with standard community care.
Ultrasound detection of knee patellar enthesitis.

We read with interest the report by Kamel et al who highlighted the use of ultrasound (US) and magnetic resonance imaging (MRI) for the detection of patellar tendon enthesitis in patients with seronegative arthropathies without typical radiographic evidence.1 Their work adds to the growing body of evidence supporting the clinical use of US in rheumatological practice. US has previously been shown to be better than clinical examination for the detection of enthesitis,2,3 but data on MRI are more limited. The authors make interesting observations about the position of the abnormalities in the patellar tendon, when compared with the Achilles tendon, possibly relating to joint biomechanics and lines of force. However, we would like to raise a few points on what we regard as important omissions from the paper. Firstly, the authors do not include the frequencies of the described US or the technical details of the MRI findings and do not state how the modalities correlated with each other. The authors also do not comment on the presence of bone marrow oedema adjacent to the enthesis on MRI. With regard to the plantar fascia, …

The effect of basic personality traits on service orientation and tendency to work in the hospitality and tourism industry

ABSTRACT This study examines the effects of basic personality traits on service orientation and tendency to work in the hospitality and tourism industry utilizing data collected from undergraduate students majoring in hospitality and tourism management in all regions of Turkey. Positive and significant relationships were found between all dimensions of basic personality traits and service orientation. Agreeableness dimension was found to have the largest effect size followed by extroversion, openness to experience, conscientiousness, and emotional stability. Furthermore, positive and significant relationships were found between all dimensions of the basic personality traits and the tendency to work in the hospitality and tourism industry. Openness was found to have the largest effect size followed by experience, extroversion, emotional stability, agreeableness, and conscientiousness on the tendency to work in the hospitality and tourism industry.
A study of a new misclassification measure for minimum classification error training of prototype-based pattern classifiers

In this paper, we revisit the formulation of minimum classification error (MCE) training and propose a sample separation margin (SSM) based misclassification measure for MCE training of multiple-prototype-based pattern classifiers. Comparative experiments are conducted on the task of the recognition of isolated online handwritten Japanese Kanji characters using Nakayosi and Kuchibue databases. Experimental results demonstrate that MCE training with the new misclassification measure achieves significant character recognition error rate reduction compared with MCE training using two traditional misclassification measures.
Dream Content in Pregnancy and Postpartum: Refined Exploration of Continuity Between Waking and Dreaming

The present study is an extension of previous work on the dreams of pregnant women, with a large sample from pregnancy and postpartum. In total, 143 pregnant women completed dream diaries during 3 distinct periods. Also, 125 nonpregnant women completed a dream diary on 1 occasion. Pregnancy- and motherhood-related oneiric characteristics, as well as negative versus positive dream elements, were coded by 2 independent judges. Results revealed that pregnant women experienced more direct in-dream representations of pregnancy and motherhood than the comparison group. However, no differences in oneiric emotional content were observed between the 2 groups. Results support the continuity hypothesis with respect to thematic representations of pregnancy but are inconclusive regarding emotional content.
The Möbius–Wall congruences for p-adic L-functions of CM elliptic curves

Abstract In this paper we prove, under a technical assumption, the so-called “Möbius–Wall” congruences between abelian p-adic L-functions of CM elliptic curves. These congruences are the analogue of those shown by Ritter and Weiss for the Tate motive, and offer strong evidences in favor of the existence of non-abelian p-adic L-functions for CM elliptic curves.
Investigating the use of digital legacies with people affected by Motor Neurone Disease (Poster Presentation- Second Place Prize)

Motor Neurone Disease (MND) is a progressive, terminal, neurological disease meaning palliative care is crucial. To date, little research has investigated how children/young people are affected when a family member has the disease and subsequently dies. As such, there is a dearth of literature on how to best support these young people. This study, using Interpretative Phenomenological Analysis (IPA), will investigate the use of digital legacies. People diagnosed with MND will record a series of video-messages about their life, accomplishments and memories specifically for a child/young person in their family. Access to the digital legacy will be given to the child/young person to use as a means of reconnecting/providing emotional support. Multiple methods have been adopted to raise awareness of the study and aid recruitment. Social media, blogs, forums, traditional newsletters and a viral campaign have been utilised to raise awareness of the study, yet, the recruitment process has still proven to be challenging. Firstly, people living with MND will be informed about the possibility of creating a digital legacy for a child/young person in their family. Once a digital legacy is recorded, or used, the person can be interviewed for the study about their experience of creating, or using, a digital legacy. Identifying and recruiting eligible participants is proving to be a significant practical issue and any suggestions or guidance are welcomed.
