Finite Element Application in Reservoir Deformation analysis (Part 1)
Authors: Ehigiator-Irughe R.
Published: October 2019

Finite element method (FEM) is a numerical technique for solving engineering problem and mathematical physics, useful problems with complicated geometries, loading, and material properties where analytical solutions may not be obtained. Some of the complicated problems involving load is a cylindrical reservoir structure where crude oil is stored in a tank farm. This paper demonstrates the use of Finite Element Analysis in above surface cylindrical reservoir engineering structure. The reservoir which has sixteen (16) monitoring station was monitored using reflectorless Total station. This paper is a pilot model and it is hoped to be developed further in two more phases to cover the entire reservoir under study. Only two studs in the North East and South East directions were selected to test the FEM forming a triangular shade (Truss) with three elements. The 2-D horizontal displacement was found to be 0.02 mm, while the vertical displacement was found to be -0.03 mm.
Cinema e Deleuze: atravessamentos possíveis no Ensino Superior e na Educação Básica
Authors: Neuscharank Angélica , Oliveira Marilda Oliveira de
Published: October 2019

The present study shares some propositions and experiments with cinema in a postgraduate discipline in Education, and in the school space with elementary students, final years. The framework of readings and moves realized through the experiences with three filmic narratives: “In Time” (2011), “Medianeras” (2011) and “The Giver” (2014) which were related to the notions that the philosopher Gilles Deleuze proposed on cinema. As methodological process, we used the mining as a possibility of producing data and this writing, because we collected and problematized the elements that affected us during the meetings, such as: speeches, readings, fragments of the films and writings, to think the conception of cinema in education. The proposed movement was to look at the films as mobilizers of thought, by situating as problematic the question - how can the filmic images activate the thought and produce writings to think education? As a result we present the meaning productions activated by students and researchers through the three films as a way of thinking, but also of looking at images in their distortions, their incipience, not in the search for truth, essence, but in the extent that seeing is letting go beyond the visible field; seeing is moving thought and also creating.

Authors: Baptaglin Leila Adriana , Borges Ferreira Paulo Fernando de Lucena
Published: October 2019

This study intends to understand the need to create Higher Courses of Indigenous Language at a distance in Institute Insikiran/UFRR. In order to enter into theoretical discussions that make possible a better understanding of this scenario, we seek to work with studies by Baniwa (2010), Bobbio (1992), Canclini (2004), Cavalcanti and César (2007), Fernandes (2008), Freitas 1999), Maher (2007), McLaren (2000). In order to systematize the data we seek to bring, in addition to the theoretical propositions, a field research with narratives of Insikiran/UFRR teachers in which it was possible to identify propositions referring to Higher Multicultural Formation in Roraima; the training needs of the Higher Education Indigenous in Roraima and the Higher Formation of indigenous language at a distance. These proposals point to the importance of the work of Insikiran/UFRR and to the possibilities to be structured for the implementation of proposals for Higher Education in Indigenous Language at a distance.

A metodologia do programa a união faz a vida: o protagonismo na primeira infância
Authors: Da Paixão Sergio Vale , Karpinski Raquel
Published: October 2019

There are countless methodological initiatives in child education to work with children. The term “project”, in the context of early childhood education, has been widely used by educators, but in several ways. The purpose of this article is to present a methodology used in a social responsibility program of a credit cooperative that uses active pedagogy through a project methodology to strengthen the continuing education of educators in brazilian schools. In the program “A União Faz a Vida”, as it is known nationally, the projects developed by children and adolescents, with the other agents of the Program, have in essence the construction and experiences of attitudes and values ??of cooperation and citizenship. Our proposal is to problematize the methodology, which has been carried out over the years with a greater presence in elementary education, approaching it to the context of children’s education, allowing a methodological review.

Health Care Costs attributable to Hospital-diagnosed Back Pain: A Longitudinal Register-based Study of the Danish Population
Authors: Søgaard Rikke , Sørensen Jan
Published: October 2019

Background: Back pain is one of most frequent musculoskeletal conditions with enormous impact to health care systems and society. Analytical studies that guide the management of this disease are strongly needed, but there is a lack of cost estimates for the attributable cost of severe or chronic back pain in particular.

Objective: The objective of this study was to estimate the health care costs attributable to hospitaldiagnosed back pain across strata of age-, gender- and diagnostic entity.

Methods: All adult Danes (N=4.3 million) were included in this longitudinal, controlled register-based study. One-year prevalence was defined according to a previously published and validated algorithm, which was applied to the Danish national patient registry. Data from other relevant health service use registries was appended along with data from the national cause of death registry in order to calculate cost rates per life year (2011 price year). The attributable health care cost was defined as the absolute difference in cost rates between individuals with versus individuals without hospital-diagnosed back pain, whereas the ratio between the two groups was used for the reporting of reference values.

Results: The health care costs attributable to hospital-diagnosed back pain were estimated at Danish Crowns (DKK) 22,700 per year for the youngest age strata (16-24 years) and increased up to DKK 72,700 per year for the oldest age strata of males (>85 years). Hospital admissions and outpatient visits accounted for the majority of these costs. The ratio of health care costs for individuals with versus individuals without the condition ranged from less than 1 to almost 6, depending on the type of service use, age and gender.

Conclusion: At the disease stage where back pain leads to contact with specialised health care, diseased individuals appear to use on average three times more health care than non-diseased individuals. This study provides detailed reference values, which can be used to inform health economic models.
The Effects of Catheter Ablation Therapy on Medication Use and Expenditures in Patients with Atrial Fibrillation
Authors: Reynolds Matthew R. , David Guy , Gunnarsson Candace , March Jamie L. , Hao Steven C.
Published: October 2019

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia encountered in clinical practice. Catheter ablation has become an important treatment option for many AF patients. Catheter ablation has been hypothesized to reduce the need for continued medical therapy for patients with AF, but there are few empirical data which demonstrate this.

Objective: The objective of this study was to estimate the impact of catheter ablation on antiarrhythmic drug (AAD) utilization and total drug expenditures among AF patients.

Methods: A retrospective analysis using the Truven Health Analytics MarketScan® Research Database was performed. Patients with AF and a catheter ablation procedure who had continuous enrollment in the database 6 months prior to their first ablation and a minimum of 1-year follow-up post first ablation were compared to AF patients who were treated with AADs and not ablation. Propensity matching was used to account for baseline differences between groups, and multivariable regression models adjusted for patient characteristics and baseline healthcare resource utilization. Sub-analyses were performed for patients age ≥65.

Results: AF patients treated with catheter ablation had significantly lower AAD utilization and total prescription drug costs than those treated with AADs only. These results persisted for the subset of patients age ≥65. The effects were strongest in the matched sample, where approximately 30% of ablation patients discontinued use of rhythm medication after receiving catheter ablation. Per-patient total medication expenditures were reduced by $800 to $1,200 per year in the matched sample.

Conclusion: Catheter ablation for AF reduced AAD utilization and total prescription drug expenditures in a sustainable fashion up to 3 years post ablation. This reduction was consistent and significant in both the non-Medicare and Medicare populations.

Authors: Patel Pankaj A. , Mallow Peter J. , Vassar Mary , Rizzo John A. , Pandya Bhavik J. , Kruzikas Denise T.
Published: October 2019

Background: Traumatic brain injury (TBI) is an increasingly diagnosed condition, but the trends in TBI visits and the cost of which have not been quantified from the hospital perspective.

Objectives: To quantify the costs of TBI stratified by inpatient and outpatient visits and to examine trends in TBI incidence over time.

Methods: This descriptive study utilized data for 2007-2012 from the Premier hospital database, which includes clinical and utilization information from hospitals across the United States. TBI was identified through International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Descriptive data were obtained to identify the TBI costs, visit costs, patient characteristics, and intertemporal trends in TBI rates.

Results: TBI patients were treated on an outpatient basis 88% of the time. Nearly 45% (44.3%) of TBI patients requiring inpatient admissions were age 65 or over, and 20% of TBI patients treated as an outpatient were age 75 or over. Children aged 4 or younger accounted for nearly 14% of TBI cases treated on an outpatient basis. TBI patients treated in the inpatient setting incurred fairly long hospital visits (mean 4.8 days; median 3.0 days) and substantial hospital costs (mean $12,717; median $8,176). The rate of TBI visits have risen substantially over time, especially among children under age 18 years and patients in the Northeast US Census Region.

Conclusion: TBI is a serious medical condition that appears to be on the rise. Large differences exist between the hospital costs associated with TBIs treated in the inpatient and outpatient settings. Further research to understand factors affecting the costs and clinical outcomes of TBI can help refine treatment strategies to enhance patient outcomes while providing cost effective care.

Suharto’s population policy in contemporary Indonesia : family planning program, marriage act or compulsory education has the greatest impact to fertility decline?
Authors: Widyastari Dyah Anantalia , Isarabhakdi Pimonpan
Published: October 2019

Fertility in Indonesia has been falling significantly, from an average total fertility rate of 5.6 children per women in 1970s to 4.1 in 1980, and 2.6 in 2010. This paper attempts to explore which and how Suharto’s population policies have played role in Indonesia’s fertility decline. Whilst the adoption of modern contraceptive was perceived as the major determinant of fertility decline in Indonesia, changes in Indonesia’s political order and socio-economic development also contribute a considerable effect to Indonesians’ familial norms. The implementation of  9-year compulsory education had placed a strong foundation for the future Indonesian human capital and enabled women to obtain higher opportunities for schooling. Beside facilitates the diffusion of ideas among young people and opened up their perspective toward reproductive rights and self actualization, education also increases women’s opportunities to participate in laborforce. With the increasing roles outside the domestic sector, delaying age of marriage and limiting family size becomes a choice for women in contemporary Indonesia. The marriage act, however, was perceived as an accelerator rather than a predictor in increasing age of first marriage. Regardless the existence of the Marriage Law 1974, age of first marriage is likely to increase with increasing of education, although maybe in a slower rate.

One-Step Direct Amination of Nanodiamond Surface and Facile Separation by Viscosity Gradient Centrifugation
Authors: Yang Nianshun , Mukerabigwi Jean Felix , Huang Xueying , Sun Yuyang , Cai Juanxiao , Cao Yu
Published: October 2019

Abstract: The introduction of terminal amine functional group on nanodiamond (ND) surface has been proposed as the key strategy to enable further synthesis of various ND derivatives for a wide range of application including sensors and biomedicine. Nevertheless, it is still challenging to develop a successful synthesis procedure to achieve monodispersed ND-NH2 mostly due to the undesirable high agglomeration effect of ND particles and complex synthetic steps which dramatically limit their practical use. In this work, we demonstrate a facile approach to obtain the direct amination of the ND surface, through a one pot mechanochemical reaction using ball milling in the presence of NH4Cl. To obtain monodispersed ND-NH2, a straightforward process by virtue of viscosity gradient centrifugation is adopted using aqueous polyvinylpyrrolidone (PVP) and glycerol. The results show a successful synthesis of ND-NH2 as evidenced by FT-IR and ζ–potential analysis. Moreover, the aminated ND particles morphology and size distribution analysis by TEM and DLS, respectively, show that using viscosity gradient built from aqueous PVP can achieve a better separation of NDs by size. Therefore, the findings suggested that the application of mechanochemical reactions and viscosity gradient centrifugation can be used to achieve homogeneous and monodispersed functionalized NDs for further specific technical applications.
Properties of Density and Velocity Gaps Induced by a Planet in a Protoplanetary Disk
Authors: Yun Han Gyeol , Kim Woong-Tae , Bae Jaehan , Han Cheongho
Published: October 2019

Gravitational interactions between a protoplanetary disk and its embedded planet are one of the formation mechanisms of gaps and rings found in recent ALMA observations. To quantify the gap properties measured in not only surface density but also rotational velocity profiles, we run two-dimensional hydrodynamic simulations of protoplanetary disks by varying three parameters: the mass ratio q of a planet to a central star, the ratio of the disk scale height h

p
to the orbital radius r

p
of the planet, and the viscosity parameter α. We find that the gap depth δ
Σ in the gas surface density depends on a single dimensionless parameter

as

, consistent with the previous results of Kanagawa et al. The gap depth δ

V
in the rotational velocity is given by

. The gap width, in both surface density and rotational velocity, has a minimum of about 4.7h

p
when the planet mass M

p
is around the disk thermal mass M
th, while it increases in a power-law fashion as M

p
/M
th increases or decreases from unity. This minimum in the gap width arises because spirals from sub-thermal planets have to propagate before they shock the disk gas and open a gap. We compare our relations for the gap depth and width with the previous results, and discuss their applicability to observations.
Enhanced Habitability on High Obliquity Bodies near the Outer Edge of the Habitable Zone of Sun-like Stars
Authors: Colose Christopher M. , Del Genio Anthony D. , Way M. J.
Published: October 2019

High obliquity planets represent potentially extreme limits of terrestrial climate, as they exhibit large seasonality, a reversed annual-mean pole-to-equator gradient of stellar heating, and novel cryospheres. A suite of 3D global climate model simulations is performed for low and high obliquity planets with various stellar fluxes, CO2 concentrations, and initial conditions to explore the propensity for high obliquity climates to undergo global glaciation. We also simulate planets with thick CO2 or H2 atmospheres, such as those expected to develop near or beyond the outer edge of the habitable zone. We show that high obliquity planets are hotter than their low obliquity counterparts due to ice-albedo feedbacks for cold climates, and water vapor in warm climates. We suggest that the water vapor greenhouse trapping is greater on high obliquity bodies for a given global-mean temperature due to the different dynamical regimes that occur between the two states. While equatorial ice belts are stable at high obliquity in some climate regimes, it is substantially harder to achieve global glaciation than for a low obliquity planet. Temperate polar conditions can be present at high obliquity at forcings for which low obliquity planets would be in a hard snowball state. Furthermore, open ocean can persist even in the winter hemisphere and when global-mean temperatures are well below freezing. However, the influence of obliquity diminishes for dense atmospheres, in agreement with calculations from 1D energy balance models.
Fermi-LAT γ-Ray Study of the Interstellar Medium and Cosmic Rays in the Chamaeleon Molecular Cloud Complex: A Look at the Dark Gas as Optically Thick H i

Published: October 2019

We report a Fermi-LAT γ-ray analysis for the Chamaeleon molecular cloud complex using a total column density (

) model based on the dust optical depth at 353 GHz (

) with the Planck thermal dust emission model. Gamma rays with energy from 250 MeV to 100 GeV are fitted with the

model as a function of

,

(α ≥ 1.0), to explicitly take into account a possible nonlinear

/

ratio. We found that a nonlinear relation, α ∼ 1.4, gives the best fit to the γ-ray data. This nonlinear relation may indicate dust evolution effects across the different gas phases. Using the best-fit

model, we derived the CO-to-

conversion factor (

) and gas mass, taking into account the uncertainties of the

model. The value of

is found to be (0.63–0.76) ×1020 cm−2 K−1 km−1 s, which is consistent with that of a recent γ-ray study of the Chamaeleon region. The total gas mass is estimated to be (6.0–7.3) × 104

, of which the mass of additional gas not traced by standard

or CO line surveys is 20%–40%. The additional gas amounts to 30%–60% of the gas mass estimated in the case of optically thin

and has five to seven times greater mass than the molecular gas traced by CO. Possible origins of the additional gas are discussed based on scenarios of optically thick

and CO-dark

. We also derived the γ-ray emissivity spectrum, which is consistent with the local

emissivity derived from Fermi-LAT data within the systematic uncertainty of ∼20%.

Quasi-periodic pulsations (QPPs) appear to be a common feature observed in the light curves of both solar and stellar flares. However, their quasi-periodic nature, along with the fact that they can be small in amplitude and short-lived, makes QPPs difficult to unequivocally detect. In this paper, we test the strengths and limitations of state-of-the-art methods for detecting QPPs using a series of hare-and-hounds exercises. The hare simulated a set of flares, both with and without QPPs of a variety of forms, while the hounds attempted to detect QPPs in blind tests. We use the results of these exercises to create a blueprint for anyone who wishes to detect QPPs in real solar and stellar data. We present eight clear recommendations to be kept in mind for future QPP detections, with the plethora of solar and stellar flare data from new and future satellites. These recommendations address the key pitfalls in QPP detection, including detrending, trimming data, accounting for colored noise, detecting stationary-period QPPs, detecting QPPs with nonstationary periods, and ensuring that detections are robust and false detections are minimized. We find that QPPs can be detected reliably and robustly by a variety of methods, which are clearly identified and described, if the appropriate care and due diligence are taken.
A Galaxy-targeted Search for the Optical Counterpart of the Candidate NS–BH Merger S190814bv with Magellan

Published: October 2019

On 2019 August 14 the Laser Interferometer Gravitational Wave Observatory (LIGO) and the Virgo gravitational wave interferometer announced the detection of a binary merger, S190814bv, with a low false alarm rate of about 1 in 1.6 × 1025 yr, a distance of 267 ± 52 Mpc, a 90% (50%) localization region of about 23 (5) deg2, and a probability of being a neutron star–black hole (NS–BH) merger of >99%. The LIGO/Virgo Collaboration (LVC) defines NS–BH such that the lighter binary member has a mass of <3 M
⊙ and the more massive one has >5 M
⊙, and this classification is in principle consistent with a BH–BH merger depending on the actual upper mass cutoff for neutron stars. Additionally, the LVC designated a probability that the merger led to matter outside the final BH remnant of <1%, suggesting that an electromagnetic (EM) counterpart is unlikely. Here we report our optical follow-up observations of S190814bv using the Magellan Baade 6.5 m telescope to target all 96 galaxies in the Galaxy List for the Advanced Detector Era catalog within the 50% localization volume (representing about 70% of the integrated luminosity within this region). No counterpart was identified to a median 3σ limiting magnitude of i = 22.2 (M

i
≈ −14.9 mag), comparable to the brightness of the optical counterpart of the binary neutron star merger GW170817 at the distance of S190814bv; similarly, we can rule out an on-axis jet typical of short GRBs. However, we cannot rule out other realistic models, such as a kilonova with only ∼0.01 M
⊙ of lanthanide-rich material, or an off-axis jet with a viewing angle of θ

Low Maternal Vitamin D and Calcium Food Intake during Pregnancy Associated with Place of Residence: A Cross-Sectional Study in West Sumatran Women, Indonesia
Authors: Aji Arif Sabta , Yerizel Eti , Desmawati Desmawati , Lipoeto Nur Indrawaty
Published: October 2019

BACKGROUND: There is a high prevalence of vitamin D deficiency in pregnancy worldwide, and variable availability of vitamin D-rich foods may affect the adequacy of vitamin D food intake in different regions.
AIM: We analysed the relationship between place of residence and maternal food intake of vitamin D and calcium in West Sumatra, Indonesia.
METHODS: This cross-sectional study was conducted in 203 pregnant women. Data collection was carried out in four districts in West Sumatra – two in coastal locations and two in mountainous locations – with subjects divided into groups based on their place of residence. The dietary intakes of pregnant women were assessed through a semi-quantitative food-frequency questionnaire (SQ-FFQ).
RESULTS: The means of maternal vitamin D and calcium food intake were 7.92 ± 5.26 µg/day and 784.88 ± 409.77 mg/day, respectively. There were no reports of vitamin D supplement intake during pregnancy. A total of 86.7% and 89.7% of the study subjects had low vitamin D and calcium food intake status, respectively. There was a significant association between maternal vitamin D intake and place of residence (p = 0.02) and significant different mean levels of vitamin D food intake with the place of residence (9.04 vs 6.55 µg/day; p = 0.01). Mothers who had higher education levels had adequate calcium food intake (p = 0.015; OR: 0.295; 0.116–0.751).
CONCLUSION: Low maternal vitamin D and calcium food intake were found to be common in West Sumatra, Indonesia and their differed between those residents in mountainous and in coastal areas.

Authors: Krishnamurthy Manjunath Nandi , Telles Shirley
Published: October 2019

The effects of yoga and ayurveda on geriatric depression were evaluated in 69 persons older than 60 who were living in a residential home. Participants were stratified by age and gender and randomly allocated to three groups: Yoga, Ayurveda, or Wait-list Control. The 15-item Geriatric Depression Scale was used to assess depressive symptoms prior to the intervention, and after 3 months and 6 months post-intervention. Participation in one of the three groups lasted 24 weeks. The yoga program (7 hours 30 minutes per week) included physical postures, relaxation techniques, regulated breathing, devotional songs, and lectures. The Ayurveda Group received an herbal preparation twice daily for the whole period. The depression symptom scores of the Yoga Group at both 3 and 6 months decreased significantly, from a group average baseline of 10.6 to 8.1 and 6.7, respectively (p < .001, paired t-test). The other groups showed no change. Hence, an integrated approach of yoga including the mental and philosophical aspects in addition to the physical practices was useful for institutionalized older persons.
Rethinking the Meaning and Significance of Journal Impact Factors
Authors: Ironside Pamela M.
Published: October 2019

Each year, nursing faculty across the country document their scholarly activities and achievements as part of the review process. This documentation takes on even greater importance when the review contributes to decisions about tenure and promotion. This review process relies on administrators, faculty colleagues, and promotion/tenure committee members evaluating the degree to which a particular program of research has influenced a specified field or discipline. Conducting a review can be a daunting task, particularly if reviewers are unfamiliar with the discipline, specialty, content area, or methodological, theoretical, or philosophical underpinnings of the methods used in the research. In such cases, reviewers often rely on impact factors (Garfield, 2005) because such calculations provide a perceived objective mechanism to assess how often others in the field are using (citing) a faculty member’s work. How are we to think about the decisions we, as members of the nursing discipline, make regarding the impact of nursing education research on extant knowledge and the practices of schooling, learning, and teaching in the discipline? Are our current practices (processes) in need of rethinking?

Published: October 2019

Measuring oxygen saturation of blood (SpO2) clinically plays a vital role in patient’s health monitoring. In fact, monitoring oxygen level is necessary for people having respiratory problems (pulmonary hypertension) and in other critical conditions. The primary motivation of this work is to develop a low cost computer-based oxygen saturation monitoring system using an embedded system along with lab windows CVI platform. The process of calculating the level of oxygen saturation in the blood using non-invasive method is also called as pulse oximetry, which consists of LED and photo detectors, using MSP430FG4618 microcontroller. The MSP430 employed in designing the microcontroller firmware program for digitization and transmission of the data from sensor to the computer. NI-based Lab windows/CVI Platform was developed as a part of this project to receive, plot, save data and determine the accuracy of SpO2 value. In this proposed system, we have achieved the maximum accuracy of 99.49% which is better than the previously developed methods. The proposed system is also designed with the low cost and low power consuming modules.

Published: October 2019

Context

Previous researchers have identified sport specialization as being associated with various negative outcomes (eg, overuse injuries and adverse psychosocial outcomes). However, little is known regarding how the underlying attitudes, beliefs, and values of sport stakeholders may be shaping this trend.

Objective

To examine the perceptions of coaches in the high school versus club sport setting and compare their attitudes and behaviors toward sport specialization.

Design

Cross-sectional survey.

Patients or Other Participants

A total of 769 coaches (497 high school coaches, 272 club sport coaches).

Main Outcome Measure(s)

Participants completed a novel measure that surveyed their perceptions regarding various aspects of youth sport specialization. Additionally, each coach completed a questionnaire detailing his or her relevant demographic and sport background information.

Results

High school coaches and club sport coaches differed in their perceptions of sport specialization (t767 = 1.41, P < .001); club coaches (2.43 ± 0.25) were more likely than high school coaches (2.31 ± 0.21) to rate specialization as a positive, adaptive practice. The multiple linear regression equations for both the high school and club coaches indicated that no educational, experiential, or demographic factors predicted coaches' perceptions of specialization (P values > .05).

Conclusions

Club sport coaches were more likely to possess attitudes in favor of sport specialization. Additionally, coaches' background characteristics did not predict their perceptions of specialization, suggesting that the competitive context itself (high school versus club) may be the most salient influencer of these perceptions. Athletes and sports medicine practitioners should be aware of the heightened expectation of specialized participation and resulting increased injury risk in these contexts. Pediatric sport researchers and practitioners should continue to explore how these different group perceptions manifest in participation behaviors and may link to overall athlete health, wellbeing, and development.
Performance appraisal as an antecedent to innovation: An analysis of its importance relative to other human resource practices
Authors: Matookchund Navin G. , Steyn Renier
Published: October 2019

Orientation: Innovation is essential to organisational survival, and several studies have shown that performance appraisals (PAs) contribute to innovation.Research purpose: The purpose of this study was to examine the importance of PA as an antecedent to innovation relative to other human resource practices (HRPs).Motivation for the study: The specific HRP drivers of innovation among employees and across organisations are not well specified, hindering appropriate resource allocation.Research approach/design and method: The PA–innovation link was investigated among 3180 employees across 53 South African organisations, utilising a cross-sectional survey design involving quantitative data, and focusing on correlation and regression analyses.Main findings: Human resource practices accounted for approximately 10% of the variance in innovation when considering individual employees. Performance appraisal was neither a common nor a unique predictor of innovation. When focusing on the link across organisations, a significant HRPs–innovation link was established in approximately 60% of organisations, with PA playing a significant role as the predictor of innovation in 10 (out of 53) organisations.Practical/managerial implications: Other HRPs, specifically supervisor support and staffing, played a much bigger role than PA in driving innovation of individuals, also across organisations. This specifies the relative importance of PA amongst other HRPs.Contribution/value-add: General managers, human resource practitioners and researchers can now use data-driven evidence to select specific HRPs which significantly enhance innovation among employees and across organisations.
Takayasu's arteritis in a Libyan female
Authors: El-Shareif Hawa
Published: October 2019

Takayasu's arteritis (TA) is a large-vessel vasculitis that involves the aorta and its major branches. Renal arteries are frequently involved, usually with renovascular hypertension. The prevalence of TA in Arabs is low. A study of the epidemiological and clinical features of TA in Arabs included 197 identified patients between 1995 and 2012 and none of them was Libyan. We report a 61-year-old Libyan woman in whom TA manifested with hypokalemia and arterial hypertension. Previous ultrasound showed renal size asymmetry raised the possibility of renal artery stenosis. The diagnosis of TA was confirmed by magnetic resonance angiography, which showed a thickened abdominal aortic wall, occlusions of the left renal artery and left common iliac artery, stenosis of the right common iliac artery, and stenosis of both subclavian arteries. TA is rarely encountered in Arabs. However, the disease must be considered in patients who present with renovascular hypertension, in a context of other autoimmune disorders.
The operator algebra content of the Ramanujan–Petersson problem
Authors: Rădulescu Florin
Published: October 2019

Let

G

be a discrete countable group, and let

\Gamma

be an almost normal subgroup. In this paper we investigate the classification of (projective, with 2-cocycle

\varepsilon\in H^2(G,\mathbb T)

) unitary representations

\pi

of

G

into the unitary group of the Hilbert space

l^2(\Gamma, \varepsilon)

that extend the (projective, with 2-cocycle

\varepsilon

) unitary left regular representation of

\Gamma

. Representations with this property are obtained by restricting to

G

(projective) unitary square integrable representations of a larger semisimple Lie group

\bar{G}

, containing

G

as dense subgroup and such that

\Gamma

is a lattice in

\bar{G}

. This type of unitary representations of of

G

appear in the study of automorphic forms.

We obtain a classification of such (projective) unitary representations and hence we obtain that the Ramanujan–Petersson problem regarding the action of the Hecke algebra on the Hilbert space of

\Gamma

-invariant vectors for the unitary representation

\pi\otimes \bar{\pi}

is an intrinsic problem on the outer automorphism group of the skewed, crossed product von Neumann algebra

{\mathcal L(G \rtimes_{\varepsilon} L^{\infty}(\mathcal G,\mu))}

, where

\mathcal G

is the Schlichting completion of

G

and

\mu

is the canonical Haar measure on

Use of Filters for Residency Application Review: Results From the Internal Medicine In-Training Examination Program Director Survey
Authors: Garber Adam M. , Kwan Brian , Williams Christopher M. , Angus Steven V. , Vu T. Robert , Hollon Matthew , Muntz Marty , Weissman Arlene , Pereira Anne
Published: October 2019

Background

The increase in applications to residency programs, known as “application inflation,” creates challenges for program directors (PDs). Prior studies have shown that internal medicine (IM) PDs utilize criteria, such as United States Medical Licensing Examination (USMLE) Step examination performance, when reviewing applications. However, little is known about how early these filters are utilized in the application review cycle.

Objective

This study sought to assess the frequency and types of filters utilized by IM PDs during initial residency application screening and prior to more in-depth application review.

Methods

A web-based request for the 2016 Internal Medicine In-Training Examination (IM-ITE) PD Survey was sent to IM PDs. Responses from this survey were analyzed, excluding non-US programs.

Results

With a 50% response rate (214 of 424), IM PDs responded that the most commonly used data points to filter applicants prior to in-depth application review were the USMLE Step 2 Clinical Knowledge score (32%, 67 of 208), USMLE Step 1 score (24%, 50 of 208), and medical school attended (12%, 25 of 208). Over half of US IM PD respondents (55%, 114 of 208) indicated that they list qualifying interview criteria on their program website, and 31% of respondents (50 of 160) indicated that more than half of their applicant pool does not meet the program's specified interview criteria.

Conclusions

Results from the 2016 IM-ITE PD Survey indicate many IM PDs use filters for initial application screening, and that these filters, when available to applicants, do not affect many applicants' decisions to apply.
Zu einigen Aspekten des Deutschen als Kontaktsprache des Slowenischen
Authors: Krevs Birk Uršula
Published: October 2019

Die Mehrdimensionalität des Sprachkontaktes zwischen Deutsch und Slowenisch zeichnet sich in der Vergangenheit und Gegenwart durch eine ausgesprochen hohe Kontaktfrequenz, -vielfalt und -intensität aus, die in der jahrhundertelangen Geschichte beider Kontaktsprachen begründet ist. Im späten Mittelalter kamen außer dem deutschsprachigen Adel und Klerus auch Fachkräfte und Beamte mit ihren Familien als Ansiedler, andererseits auch Kolonisten, die in Zarz/Sorica und Deutschruth/Rut wie auch der Gottschee/Kočevsko ansässig wurden. 1918 wurden die Deutschen im neu gegründeten Staat zur Minderheit, durch die Grenzziehung auch die Abstaller Deutschen. Die Zarzer Sprachinsel wurde assimiliert, die Gottscheer Minderheit, die einst größte Sprachinsel, löste sich infolge der Umsiedlung und Vertreibung auf. Unter den zahlreichen Kontaktsprachen des Deutschen ist das Slowenische sowohl seine autochthone als auch seine allochthone Kontaktsprache. Autochthon ist sie nach wie vor im Süden des zusammenhängenden deutschen Sprachraums, im zweisprachigen Kärnten und Teil der Steiermark, als allochthone Sprache ist es eine von vielen Migrantensprachen auf dem geschlossenen deutschsprachigen Gebiet infolge von verschiedenen Auswanderungswellen seit der zweiten Hälfte des 19. Jahrhunderts.Aus der Sicht des Varietätenkontaktes stand das Slowenische durch die Zeit hindurch in Kontakt mit allen hochdeutschen Chronolekten. Diatopisch steht das Slowenische nach wie vor mit dem Südbairischen in Kontakt. Diastratisch ist als Gebersprache Deutsch mit wienerischer Prägung bedeutsam. Aufgrund von Konvergenzprozessen wurden im Kontaktareal Altösterreich aus dem Deutschen viele Lehnwörter ins Slowenische übernommen und einige wenige auch aus dem Slowenischen ins Deutsche. Zeugnis intensiver interkultureller Einwirkungen sind auch ausgewählte Toponymika beider Sprachen, da viele deutsche Toponyme slowenisches und viele slowenische Toponyme deutsches Sprachmaterial aufweisen. Auch deutsch-slowenische toponymische Namenpaare widerspiegeln die historische und aktuelle Mehrsprachigkeit.
Continuous reducibility: functions versus relations
Authors: Camerlo Riccardo
Published: October 2019

It is proved that the Tang-Pequignot reducibility (or reducibility by relatively continuous relations) on a second countable, T0 space X either coincides with the Wadge reducibility for the given topology, or there is no topology on X that can turn it into Wadge reducibility.
On definable completeness for ordered fields
Authors: Moniri Mojtaba
Published: October 2019

We show that there are 0-definably complete ordered fields which are not real closed. Therefore, the theory of definably with parameters complete ordered fields does not follow from the theory of 0-definably complete ordered fields. The mentioned completeness notions for ordered fields are the definable versions of completeness in the sense of Dedekind cuts. In earlier joint work, we had shown that it would become successively weakened if we just required nonexistence of definable regular gaps and then disallowing parameters. The result in this note shows reducing in the opposite order, at least one side is sharp.
Reductions between certain incidence problems and the continuum hypothesis
Authors: Da Silva Samuel Gomes
Published: October 2019

In this work, we consider two families of incidence problems, C1 and C2,, which are related to real numbers and countable subsets of the real line. Instances of problems of C1 are as follows: given a real number x, pick randomly a countable set of reals A hoping that x ∈ A, whereas instances of problems of C2 are as follows: given a countable set of reals A, pick randomly a real number x hoping that x ∉ A. One could arguably defend that, at least intuitively, problems of C2 are easier to solve than problems of C1. After some suitable formalization, we prove (within ZFC) that, on one hand, problems of C2 are, indeed, at least as easy to solve as problems of C1. On the other hand, the statement “Problems of C1 have the exact same complexity of problems of C2” is shown to be an equivalent of the Continuum Hypothesis.
