Häusliche Heiligkeit
Authors: Weitbrecht Julia
Published: March 2015

This article investigates historical conceptualizations of sanctity in medieval saints’ legends. Sanctity, in its textual representations, emerges from the interaction of traditional legendary narratives, their textual transmission, and varying models of imitability. The legend of St Oswald illustrates the versatility of the saint as persona imitabilis: While historical accounts describe Oswald as a missionary king and martyr, the ›Munich Oswald‹ links the motif of conversion by marriage to the narrative model of the bridal quest. Simultaneously, the feudal aspects of the bridal quest are questioned by references to sanctification by renunciation. This aporetical constitution of sanctity is retold and harmonized in the Berlin manuscript mgq 478. Most of the included narratives have been edited so that they lead to a happy ending. The ›Berlin Oswald‹ thus provides another new model of imitability, the socially acceptable saint, which allows for a better understanding of late medieval conceptualizations of sanctity as well as saints’ legends as a narrative genre.

Dynamical analysis of the avian-human influenza epidemic model using the semi-analytical method
Authors: Jabbari Azizeh , Kheiri Hossein , Bekir Ahmet
Published: March 2015

In this work, we present a dynamic behavior of the avian-human influenza epidemic model by using efficient computational algorithm, namely the multistage differential transform method(MsDTM). The MsDTM is used here as an algorithm for approximating the solutions of the avian-human influenza epidemic model in a sequence of time intervals. In order to show the efficiency of the method, the obtained numerical results are compared with the fourth-order Runge-Kutta method (RK4M) and differential transform method(DTM) solutions. It is shown that the MsDTM has the advantage of giving an analytical form of the solution within each time interval which is not possible in purely numerical techniques like RK4M.
A Novel Smooth Gauss–Semi-Markov Mobility Model for Mobile Wireless Networks
Authors: Zhang Hengyang , Zheng Bo , Zhuo Kun
Published: March 2015

Mobility model serves as the basis of protocol design and simulation in mobile wireless networks. In this paper, we propose a novel mobility model for mobile wireless networks, named smooth Gauss–semi-Markov (SGM) mobility model. Introducing Gauss and semi-Markov processes, the model can characterize the smooth movement of mobile users in accordance with the physical law of motion in order to eliminate sharp turns, abrupt speed change and sudden stops exhibited by existing mobility models. The SGM model consists of five consecutive phases: acceleration phase, stable phase, turn phase, deceleration phase and pause phase, including almost all kinds of movement states in realistic conditions. Through stochastic analysis, we prove mathematically the time stationary average speed and uniform spatial node distribution in the SGM model. The model can be easily and flexibly applied for simulating node mobility in mobile wireless networks. By adjusting parameters, many existing mobility models widely used at present, such as the Random Walk, Random Direction, Modified Random Direction, Gauss–Markov, Semi-Markov Smooth, Smooth Random mobility models, etc., can be derived from the SGM model. We show the unity and generality of the SGM model by NS-2 simulations.
Multi-band Monopole Antennas Loaded with Metamaterial TL
Authors: Song Zhi-jie , Liang Jian-gang
Published: March 2015

A novel metamaterial transmission line (TL) by loading complementary single Archimedean spiral resonator pair (CSASRP) is investigated and used to design a set of multi-frequency monopole antennas. The particularity is that the CSASRP which features dual-shunt branches in the equivalent circuit model is directly etched in the signal strip. By smartly controlling the element parameters, three antennas are designed and one of them covering UMTS and Bluetooth bands is fabricated and measured. The antenna exhibits impedance matching better than –10 dB and normal monopolar radiation patterns at working bands of 1.9–2.22 and 2.38–2.5 GHz. Moreover, the loaded element also contributes to the radiation, which is the major advantage of this prescription over previous lumped-element loadings. The proposed antenna is also more compact over previous designs.
National and post-national discourses and the construction of linguistic identities by students of Albanian origin in Greece
Authors: Archakis Argiris
Published: March 2015

Drawing on Critical Discourse Analysis and, more specifically, on the relationship between the macro-level of dominant discourses and the micro-level of individual positionings, we examine the way linguistic identities are constructed by immigrant students of Albanian origin in Greece. We elaborate on two ‘competitive’ discourses: the national, homogenizing one and the post-national, deconstructing one, and the way they influence the construction of immigrant students’ linguistic identities. Our data come from lyceum immigrant students’ essays which are analyzed in order to trace their positionings towards the two ‘competitive’ discourses, and in particular, towards the linguistic dimension of these discourses. For a systematic investigation of immigrant students’ linguistic identities we employ the membership categorization device
Social Media in Archives and Libraries: A Snapshot of Planning, Evaluation, and Preservation Decisions
Authors: Liew Chern Li , King Vanessa , Oliver Gillian
Published: March 2015

This paper reports the findings from research which explored decision making and practices underpinning the implementation or non-adoption of social media in archives and libraries worldwide. Archives and libraries continue to face demands, whether from senior management, funding agencies, the government, or taxpayers to demonstrate accountability. Evaluation provides evidence to meet such demands and to gain, validate, or sustain support for programs and activities. Being able to show success is a key step for archives and libraries that need to rationalize or win support for the continuance of their social media efforts. Related to this are questions about whether or not there should be a preservation strategy for the content of social media as well as a plan for sustainability of infrastructure to support these activities. Our survey findings suggest that archives and libraries know that they are not necessarily choosing the evaluation methods that can best demonstrate the achievement of their intentions, and furthermore that they lack strategies and policies for preservation and sustainability.
Effect of Fractionation of Reclaimed Asphalt Pavement on Properties of Superpave Mixtures With Reclaimed Asphalt Pavement
Authors: Sabahfer N. , Hossain M.
Published: March 2015

While the necessity for cost effective and sustainable replacements for virgin paving mixtures is becoming more and more evident in recent years, particularly with asphalt binder and aggregate economics and the obligations for using greener alternatives, contradictory performance results of high percentages of reclaimed asphalt pavement (RAP) in Superpave mixtures have made the addition of RAP to hot mix asphalt (HMA) quite challenging. Obtaining RAP involves milling and processing that produces an excessive amount of fine aggregates, making it difficult to control the final HMA volumetric properties, especially when higher amounts of RAP are used. In addition, segregation in RAP stockpiles is a common phenomenon which causes difficulties in air void control of the final mix due to higher asphalt content of fine aggregates. Fractionation is a process in which RAP is separated into at least two sizes, typically one coarse and one fine fraction, in order to ensure consistency of RAP. Fractionation is now being increasingly specified for inclusion of higher volumes of RAP in Superpave mixtures; however, whether any improvements of mechanical properties of HMA can be obtained by fractionation is virtually unknown. In this study, the effect of increasing RAP percentage, source of RAP, and replacing RAP with fractionated RAP on the performance of Superpave HMA mixtures was investigated in terms of rutting, freeze-thaw resistance, and cracking resistance by conducting Hamburg wheel track device (HWTD), moisture susceptibility, and complex modulus tests. HMA mixtures in this study were made with the same virgin aggregates and virgin binder using two different sources of RAP by increasing RAP amount from 20 to 40 %. Results showed that the performance can be different based on the aged binder and quality of aggregates in RAP; moreover, the fractionation effect was found to be insignificant on enhancing the performance of Superpave mixtures with RAP.

Authors: Harvengt Julie , Boizeau Priscilla , Chevenne Didier , Zenaty Delphine , Paulsen Anne , Simon Dominique , Guilmin Crepon Sophie , Alberti Corinne , Carel Jean-Claude , Léger Juliane
Published: March 2015

Objective

To assess in a pediatric population, the clinical characteristics and management of triiodothyronine-predominant Graves' disease (T3-P-GD), a rare condition well known in adults, but not previously described in children.

Design

We conducted a university hospital-based observational study.

Methods

All patients with GD followed for more than 1 year between 2003 and 2013 (n=60) were included. T3-P-GD (group I) was defined as high free T3 (fT3) concentration (>8.0 pmol/l) associated with a normal free thyroxine (fT4) concentration and undetectable TSH more than 1 month after the initiation of antithyroid drug (ATD) treatment. Group II contained patients with classical GD without T3-P-GD.

Results

Eight (13%) of the patients were found to have T3-P-GD, a median of 6.3 (3.0–10.5) months after initial diagnosis (n=4) or 2.8 (2.0–11.9) months after the first relapse after treatment discontinuation (n=4). At GD diagnosis, group I patients were more likely to be younger (6.8 (4.3–11.0) vs 10.7 (7.2–13.7) years) and had more severe disease than group II patients, with higher serum TSH receptor autoantibodies (TRAb) levels: 40 (31–69) vs 17 (8–25) IU/l, P<0.04, and with slightly higher serum fT4 (92 (64–99) vs 63 (44–83) pmol/l) and fT3 (31 (30–46) vs 25 (17–31) pmol/l) concentrations. During the 3 years following T3-P-GD diagnosis, a double dose of ATD was required and median serum fT4:fT3 ratio remained lower in group I than in group II.

Conclusion

Severe hyperthyroidism, with particularly high TRAb concentrations at diagnosis, may facilitate the identification of patients requiring regular serum fT3 determinations and potentially needing higher doses of ATD dosage during follow-up.

Published: March 2015

Objective

Unilateral adrenalectomy is the first-line treatment for aldosterone-producing adenomas (APA). Hyperkalemia after adrenalectomy because of contralateral zona glomerulosa insufficiency has been reported. We investigated clinical risk factors to predict postoperative hyperkalemia in patients with APA undergoing adrenalectomy.

Design and methods

This study was conducted by retrospectively reviewing medical records from 2000 to 2012 at Seoul National University Hospital and two other tertiary centers. Data from 124 patients who underwent adrenalectomy were included. Hyperkalemia was defined as serum potassium >5.5 mmol/l. Clinical preoperative risk factors included age, blood pressure, plasma renin activity (PRA), plasma aldosterone concentration (PAC), serum potassium, serum creatinine, glomerular filtration rate (GFR), the mass size on pathology, and mineralocorticoid receptor (MR) antagonist use.

Results

Out of 124 patients, 13 (10.5%) developed postoperative hyperkalemia. The incidences of transient and persistent hyperkalemia were 3.2 and 7.3% respectively. Preoperative PRA and PAC were not significantly different in postoperative hyperkalemic patients compared with normokalemic patients. Patients with persistent hyperkalemia were older, had a longer duration of hypertension, larger mass size on pathology, and lower GFR (all P<0.05). The incidence of postoperative hyperkalemia was not different between MR antagonist users and non-users.

Conclusion

Older age (≥53 years), longer duration of hypertension (≥9.5 years), larger mass size on pathology (≥1.95 cm), and impaired preoperative renal function (GFR <58.2 ml/min) were associated with prolonged postoperative hyperkalemia in patients with APA. MR antagonist use did not prevent postoperative hyperkalemia.
Molecular aspects of bovine cystic ovarian disease pathogenesis
Authors: Ortega Hugo H , Marelli Belkis E , Rey Florencia , Amweg Ayelen N , Díaz Pablo U , Stangaferro Matías L , Salvetti Natalia R
Published: March 2015

Cystic ovarian disease (COD) is one of the main causes of reproductive failure in cattle and causes severe economic loss to the dairy farm industry because it increases both days open in thepost partumperiod and replacement rates due to infertility. This disease is the consequence of the failure of a mature follicle to ovulate at the time of ovulation in the estrous cycle. This review examines the evidence for the role of altered steroid and gonadotropin signaling systems and the proliferation/apoptosis balance in the ovary with cystic structures. This evidence suggests that changes in the expression of ovarian molecular components associated with these cellular mechanisms could play a fundamental role in the pathogenesis of COD. The evidence also shows that gonadotropin receptor expression in bovine cystic follicles is altered, which suggests that changes in the signaling system of gonadotropins could play a fundamental role in the pathogenesis of conditions characterized by altered ovulation, such as COD. Ovaries from animals with COD exhibit a disrupted steroid receptor pattern with modifications in the expression of coregulatory proteins. These changes in the pathways of endocrine action would trigger the changes in proliferation and apoptosis underlying the aberrant persistence of follicular cysts.

Published: March 2015

Growth of GaN on Si(111) and Ge coated Si(111) using pulsed electron beam deposition (PED) process is reported. GaN was deposited on Si(111) and Ge/Si(111) at 600°C in an N2 environment without any surface pre-treatment such as pre-nitridation. X-ray diffraction confirmed that c-plane oriented GaN was grown. Photoluminescence showed near-band-edge emission, the intensity of which was improved with hydrogen passivation. Electrical characterization showed n-type conductivity with room temperature electron mobilities in the range of 300 cm2/V-sec.

One of the main areas of improvement in capacitive deionization technologies is the materials used for electrodes which have very specific requirements. In the present work, a wide range of material characterization techniques are employed to determine the suitability of a multiwall carbon nanostructure thin film as electrode material. The electrical, mechanical, surface and wetting characteristics are studied proving the membrane highly conductive (σ=7.25 103 S/m), having competitive electro-sorption capacity (11.7 F/g at 10 mV/s) and surface area (149 m2/g), strain rate dependent mechanical properties and hydrophobic wetting behavior.

CKD is increasingly prevalent in pregnancy. In the Torino-Cagliari Observational Study (TOCOS), we assessed whether the risk for adverse pregnancy outcomes is associated with CKD by comparing pregnancy outcomes of 504 pregnancies in women with CKD to outcomes of 836 low-risk pregnancies in women without CKD. The presence of hypertension, proteinuria (>1 g/d), systemic disease, and CKD stage (at referral) were assessed at baseline. The following outcomes were studied: cesarean section, preterm delivery, and early preterm delivery; small for gestational age (SGA); need for neonatal intensive care unit (NICU); new onset of hypertension; new onset/doubling of proteinuria; CKD stage shift; “general” combined outcome (preterm delivery, NICU, SGA); and “severe” combined outcome (early preterm delivery, NICU, SGA). The risk for adverse outcomes increased across stages (for stage 1 versus stages 4–5: “general” combined outcome, 34.1% versus 90.0%; “severe” combined outcome, 21.4% versus 80.0%; P<0.001). In women with stage 1 CKD, preterm delivery was associated with baseline hypertension (odds ratio [OR], 3.42; 95% confidence interval [95% CI], 1.87 to 6.21), systemic disease (OR, 3.13; 95% CI, 1.51 to 6.50), and proteinuria (OR, 3.69; 95% CI, 1.63 to 8.36). However, stage 1 CKD remained associated with adverse pregnancy outcomes (general combined outcome) in women without baseline hypertension, proteinuria, or systemic disease (OR, 1.88; 95% CI, 1.27 to 2.79). The risk of intrauterine death did not differ between patients and controls. Findings from this prospective study suggest a “baseline risk” for adverse pregnancy-related outcomes linked to CKD.
Improving the Role of the Teaching Hospital in the Clinical Clerkship
Authors: Kim Young Chang
Published: March 2015

The mission of the modern medical school includes education, research, and patient care. The clinical clerkship is an important part of the core curriculum, and hospital facilities are needed for the clinical clerkship. However, unfortunately, education has moved to the periphery during the past several decades because of the dominance of research and patient care. This may lead to obstacles in the education of future physicians in the long term. To promote their education mission, teaching hospitals need to recognize and share the importance of this mission. In addition to the certification of teaching hospitals, a new paradigm for teaching hospitals should be introduced to produce a high quality clinical clerkship and postgraduate medical education. The relevant government departments need to allocate and expand financial support to medical schools and teaching hospitals, and to unify supervision of basic and postgraduate medical education.
The Student Internship Experience
Authors: Choi Son-Hwan
Published: March 2015

Recently, the student internship has been introduced in medical schools as a way of preparing students with training experience and medical knowledge by performing clinical practice. This study discusses student internship management and ways to operate the internship effectively. Catholic University of Daegu School of Medicine has set up a 6-week internship program for fourth-year undergraduate students. In most of the sections, students have shown their satisfaction, particularly when they have received appropriate feedback and attention from their professors. The students found that performing the evaluation and treatment of patients and individual chart recording were informative and helpful. However, they felt a lack of basic knowledge and clinical skills and had difficulty in understanding their roles and in time management. The success of an internship depends on the passion and interest that professors show for their students along with active support from the other faculty and thoughtful consideration of patients and all their friends and family members. In addition, with growing awareness of the need for the student internship, it is necessary that the school executive provide financial and administrative support to the faculty and staff, clarify roles and the work needed to perform the tasks, ensure substantiality of the individual program with professors or departments, provide enough preliminary courses, and monitor outcomes and reflection.

Novel High Density Brine-Based Drill-In Fluids Significantly Increased Temperature Limit for HP/HT Applications
Authors: Zhou Hui , Deville Jay P. , Davis Chesnee L.
Published: March 2015

Drill-in fluids, also known as reservoir drilling fluids, are specifically designed to help minimize formation damage and facilitate wellbore cleanup. Typical water-based drill-in fluids use brines to achieve a desired fluid density and rely on acid-soluble solids, such as calcium carbonate, for bridging of pore spaces. Biopolymers, such as xanthan gum and crosslinked starch, are generally used as viscosifiers and fluid-loss additives for the drill-in fluids. Unfortunately, these biopolymers begin to degrade at temperatures greater than 275°F. As a result, conventional water-based drill-in fluids are generally limited to wells with temperatures below 300°F. Clay-free, brine-based drill-in fluids for temperatures greater than 300°F still pose challenges in high-pressure/high-temperature (HP/HT) conditions.

Novel high density brine-based drill-in fluids have been developed using a specifically designed dual-functional polymer as a thermally stable viscosifier and fluid-loss additive. Divalent brines, such as CaBr2 (14.2 lbm/gal) and CaCl2 (11.6 lbm/gal), were used as the base fluids. The drill-in fluids show similar thixotropic behavior to those biopolymer-based, yet exhibit excellent thermal stability up to 450°F, which is at least 150°F higher than typical drill-in fluids. After static aging at 450°F for 16 hours, the fluids exhibited only slight color change, and no stratification or solid settling was observed. Rheological properties of the aged samples increased slightly compared to samples before aging. The samples still provided excellent fluid-loss control, even after aging, with a measured HP/HT fluid loss less than 10 mL after 30 minutes at 350°F. Core flow testing showed that the drill-in fluid is nondamaging after acid breaker treatment, with a return permeability of 100%.
Agronomic Management and Fungicide Effects on Oat Yield and Quality
Authors: Mourtzinis Spyridon , Conley Shawn P. , Gaska John M.
Published: March 2015

Oat (Avena sativa L.) is an important crop in the U.S. The primary uses for oat in Wisconsin are for establishing alfalfa (Medicago sativa L.) underseedings, livestock forage, grain, and straw production, and for human nutrition. Therefore, the quantitative and qualitative characteristics of oat are of great importance. The objective of this study was to detect the effects of variety, seeding rate, seed treatment, and foliar fungicide on total grain yield, groat proportion, test weight, plant height, lodging severity, and β‐glucan content using data from two separate trials which were established from 2011 to 2013 at the University of Wisconsin Arlington Agricultural Research Station. The results from the two 3‐yr studies highlight the importance of selecting an appropriate oat variety with superior yield and quality characteristics. The use of a high seeding rate had no effect on any of the examined characteristics. However, treated seeds with Rancona Crest exhibited increased groat yield compared to untreated seeds by 187 kg ha−1. An important finding of this study is that the use of a foliar fungicide increased total and groat yields, and reduced lodging severity without impacting β‐glucan content. The results of this study indicate that the use of a superior variety such as ‘Badger’ and ‘BetaGene’, use of Rancona Crest seed treatment, and use of Headline foliar fungicide can increase oat yields in Wisconsin without reducing the crops’ quality characteristics.

Published: March 2015

Water shortage is the major constraint for biomass production in semiarid regions. Biomass production of milk thistle [Silybum marianum (L.) Gaertn] and energy balance of this crop under different irrigation regimes (full and deficit irrigation) and soil organic amending treatments (poultry manure [PM] and vermicompost [VC]) was evaluated in a two‐year field experiment. Biomass yield reduced by 10 and 22% under moderate (I75) and severe deficit (I50) irrigation, respectively. Under deficit irrigation, the contribution of leaves and heads to the final biomass reduced in favor of the stalk. Regardless of the irrigation regime, application of soil amendments improved biomass yield. Total energy input used for milk thistle production was 9829 MJ ha−1, in which 68% was related to nonrenewable energy sources. Diesel fuel (51%) had the biggest share of energy used for milk thistle production, followed by irrigation water and machinery. Energy input in I75 and I50 was 7 and 15% less than full irrigation (I100). Net energy obtained from milk thistle was 116,688 MJ ha−1 with energy efficiency (energy output/energy input ratio) of 12.8. Taking into account that milk thistle is an annual crop with low energy input requirements, it seems that milk thistle has a considerable potential for biomass production using I75 in regions with limited irrigation water availability.
Organic Carbon Content in the Soil Master Horizons of South Africa
Authors: Rantoa N. R. , van Huyssteen C. W. , du Preez C. C.
Published: March 2015

The status and spatial variability of organic C levels in soils that were never cultivated but were grazed are a function of environmental and inherent soil properties. The organic C content in South African soils was therefore quantified using existing data with reference to master horizon classification and soil‐forming factors. Data from 7079 soil profiles covering the whole of South Africa, including land type survey modal profiles and profiles from other soil surveys, were used in this study. All profiles were analyzed for physical and chemical properties including organic C. The average organic C content ranged from 16% in the O horizon to 0.3% in the C horizons and decreased in the sequence O > A > G > B > E > C. The organic C content was correlated to the soil‐forming factors climate (rainfall, evaporation, and aridity index), topography (terrain morphological units, slope percentage, slope type, and slope aspect), and soil texture (clay content). There was therefore a circular influence among topography, master horizons, and organic C contents. A regression was further done to correlate organic C per master horizon with rainfall, evaporation, slope aspect, aridity index, and clay content. Unfortunately most of theR2values were too low for the equations to be used to estimate organic C content in the master horizons of South African soils.
Adsorption of polycyclic aromatic hydrocarbons from wastewater by using silica-based organic–inorganic nanohybrid material
Authors: Balati Ali , Shahbazi Afsaneh , Amini Mostafa M. , Hashemi Seyed Hossein
Published: March 2015

Polycyclic aromatic hydrocarbons (PAHs) are a group of priority pollutants, which are classified as persistent hazardous contaminants. Herein, the adsorption of three PAHs, naphthalene (NAP), acenaphthylene (ACN), and phenanthrene (PHN), from wastewater onto NH2-SBA-15 organic–inorganic nanohybrid material as a function of pH of the media (2–10), sorbent dosage (0.5–3.5 g L−1), PAH concentration (1–18 mg g−1), and temperature (25–45 °C) were elucidated. The prepared adsorbents were characterized by scanning electron microscope, transmission electron microscopy, X-ray diffractions, and thermogravimetric analysis. Among Langmuir, Freundlich, and Temkin isotherms models, it was found that the Langmuir model gave an excellent overall fit (R2 > 0.97). The maximum adsorption capacity of 1.92, 1.41, and 0.76 mg g−1 was obtained for NAP, ACN, and PHN, respectively. Adsorption kinetics of PAHs onto NH2-SBA-15 was in accordance with the pseudo-second-order model, providing evidence that pore mass transferring was involved. PAHs' adsorption was strongly dependent on temperature, and confirmed the spontaneous and endothermic nature of the process. The optimized sorption condition was successfully applied to the real petroleum refinery wastewater samples and the adsorption capacity of NH2-SBA-15 was satisfactory for PAHs' studies as 1.67, 1.06, and 0.24 mg g−1 for NAP, ACN and PHN, respectively. Furthermore, reusability was successfully tested by five sequential recoveries.
Cake porosity analysis using 1D–3D fractal dimensions in coagulation–microfiltration of NOM
Authors: Raspati G. S. , Leiknes T. O.
Published: March 2015

Fouling during coagulation–ceramic microfiltration of natural organic matter was investigated. Two process configurations (inline coagulation (IC) and tank coagulation (TC)) and two process conditions (types of coagulants–aluminum-based PAX and iron-based PIX–and G-values) were studied. The rate of irreversible fouling corresponding to the increase of initial transmembrane pressure after backwash of IC-PAX was lowest followed by TC-PAX and TC-PIX, while the performance of IC-PIX was found worst. The 1D and 2D fractal analysis revealed that flocs from IC were morphologically different from those of TC, leading to different filtration characteristics. The 3D fractal analysis revealed two groups of morphologically similar flocs: one led to successful filtration experiments, whereas the other led to unsuccessful ones. Cake porosity was found dependent on the floc morphology. Thus, such an approach was found complementary with fouling analysis by means of a membrane fouling model and minimization of fouling phenomenon was achieved by combining the two approaches.
Regional Patterns in the Otolith Chemistry of Juvenile Spotted Seatrout
(Cynoscion nebulosus) Differ under Contrasting Hydrological Regimes
Authors: Rakocinski Chet F. , Comyns Bruce H. , Peterson Mark S. , Shiller Alan M.
Published: March 2015

The value of using otolith chemistry to characterize recruitment in terms of natal source regions depends on
how consistently spatio-temporal variation can be resolved. The objective of this study was to compare regional classification
patterns in the otolith chemistry of juvenile Spotted Seatrout (Cynoscion nebulosus) between two years experiencing
disparate hydrological regimes, and separated by a five year interlude. Spatial patterns in the whole-otolith chemistry of
juveniles of this estuarine-dependent species were compared between years using five otolith elements and two stable isotopes.
Consistent size-related trends in uptake and deposition were evidenced by parallel ontogenetic relationships for six
otolith variables. Nine natal regions were discerned equally well in both years; and region accounted for similar overall
amounts of variation in the seven otolith variables in both years. However, the otolith variables did not distinguish the
nine regions in the same manner in both years, and natal regions varied in how similar they were in otolith chemistry between
years. Consequently, between-year cross-classification accuracy varied widely among regions, and geographic distance
per se was unimportant for explaining regional patterns in otolith chemistry. Salinity correlated significantly with
regional patterns in otolith chemistry in 2001, but not at all in 2006 when conditions were much drier. Regional patterns in
individual otolith variables reflected either a general trend based on hydrology, a regional-local effect whereby geographically
closer regions exhibited similar otolith chemistry, or a location-specific effect for which there was either no correlation
in otolith concentration among regions between years, or a significant but individualistic relationship. In addition to
elucidating limitations of using otolith chemistry to identify natal source regions or for tracking fish movements, knowing
more about how and why otolith chemistry varies could be used to address specific questions about early recruitment dynamics,
or to aid in the development of more reliable instruments for discerning natal source contributions.
Ontological Security in Nursing Homes for Older Persons – Person-Centred Care is the Power of Balance
Authors: James Inger , Ardeman-Merten Rebecka , Kihlgren Annica
Published: March 2015

Introduction:

The Swedish national guidelines for elderly care describe how older persons should be able to trust that their care is permeated with security. Different theoretical perspectives can be found that describe what creates security. Many studies have been done about security. However, few studies have explicitly asked older persons what security in nursing homes means to them.

Aim:

The aim of the study was to describe how older persons in nursing homes talked and reflected about security in their daily lives.

Method:

Nine older persons were interviewed in, in-depth interviews one to three times and the resulting data was analysed using content analysis.

Results:

The older persons adapted to having their own needs and those of the other older persons met and to the staff routines which created a sense of security. At the same time, they longed for security in which they could trust themselves and create their own daily life. Further to have a sense of belonging and of being liked for created an internal, interpersonal and external security. This can be linked to an ontological security which means having a sense of confidence in the continuity of self-identity and order in events, a being in the world.

Conclusion:

Person-centred instead of institution- centred care can provide the balance of power that allows the older person to obtain ontological security in which the staff's ability to create a relationship with the older persons becomes crucial.
Anaerobic Digestion of Algae Biomass to Produce Energy during Wastewater Treatment
Authors: Peng Shanshan , Colosi Lisa M.
Published: March 2015

Water resource recovery facilities (WRRFs) are asked to improve both energy efficiency and nutrient removal efficacy. Integration of algaculture offers several potential synergies that could address these goals, including an opportunity to leverage anaerobic digestion at WRRFs. In this study, bench‐scale experiments are used to measure methane yield during co‐digestion of Scenedesmus dimorphus or mixed WRRF‐grown algae with WRRF biosolids. The results indicate that normalized methane yield decreases with increasing algae content in a manner than can be reasonably well fit using linear regression (R2 = 67%). It is thus possible to predict methane yield for any mixture of algae and biosolids based on the methane yield of the biosolids alone. Using revised methane yields, the energy return on investment of a typical WRRF increases from 0.53 (without algae) to 0.66 (with algae). Thus, algae‐based wastewater treatment may hold promise for improving WRRF energy efficiency without compromising effluent quality.
The Reduced Opportunity Structure: Senior Faculty Movement in Accounting 1980–2012
Authors: Fogarty Timothy J. , Black William H.
Published: March 2015

The ability to move from one employing institution to another can be very important in an academic career. This study concerns the mid-career opportunities for institutional migration for accounting faculty. Unlike previous studies that focused on the characteristics, motivations, and attainments of mobile faculty, this study examines the relative size of the accounting professoriate that has been in transition at various points in time. When a large component of senior accounting academics have (have not) taken new positions in the last few years, the opportunity structure can be said to be high (low). The findings, using accounting doctoral schools as the empirical setting, document a declining opportunity set. Over time, the fraction of senior accounting academics that have changed schools in the previous five years has dwindled. This conclusion holds true across various divisions of academic accounting. Specifically, a decline is shown for both public schools and private schools, for higher and lower prestige schools, and for most sub-fields of the accounting discipline. The paper offers implications about this long-term trend.
Management Innovation – Designing And Testing A Theoretical Model
Authors: Bezdrob Muamer , Šunje Aziz
Published: March 2015

Management innovation – the introduction of management processes, structures and practices that are new to companies, is crucial to business success. Based on the existing literature on management innovation and a rigorous theoretical approach to model design and development, a theoretical model of management innovation that is applicable to immature and underdeveloped markets was designed. Using this model, the study shows that the context in which companies operate, as well as companies’ management background (proficiency), are directly and positively related to management innovation. The main implication of the research is that the existing management innovation theory is applicable to market conditions in the Federation of Bosnia and Herzegovina with only slight adaptation. Furthermore, this research provides important insights about the factors that affect the companies’ readiness to introduce innovative management structures, processes and practices.
Pre-service Teachers’ Views of Their Training: Key Issues to Sustain Quality Teacher Education
Authors: Flores Maria Assunção , Santos Patrícia , Fernandes Sandra , Pereira Diana
Published: March 2015

This paper draws upon data from a broader piece of research aimed at examining pre-service teachers' views of their initial teacher education within the context of a master’s degree programme in teaching. The data were collected through questionnaires and written narratives at the beginning and at the end of the programme. In this paper, the data arising from 47 narratives at the end of the programme are presented. Five categories emerged from the qualitative data: curriculum content, teaching practice, the role of teacher educators, teaching and learning methods, the organisational aspects and structure of the programme. Although the participants identified positive aspects of the initial teacher education programme, they also stress that there is room for improvement, especially with regard to a greater coherence of the curriculum and a better articulation of its different components. Implications of the findings for enhancing the quality of initial teacher education and the role of teachers’ educators are discussed.
Other-initiated repair in English
Authors: Kendrick Kobin H.
Published: March 2015

The practices of other-initiation of repair provide speakers with a set of solutions to one of the most basic problems in conversation: troubles of speaking, hearing, and understanding. Based on a collection of 227 cases systematically identified in a corpus of English conversation, this article describes the formats and practices of other-initiations of repair attested in the corpus and reports their quantitative distribution. In addition to straight other-initiations of repair, the identification of all possible cases also yielded a substantial proportion in which speakers use other-initiations to perform other actions, including non-serious actions, such as jokes and teases, preliminaries to dispreferred responses, and displays of surprise and disbelief. A distinction is made between otherinitiations that perform additional actions concurrently and those that formally resemble straight other-initiations but analyzably do not initiate repair as an action.

The authors report the case of a 15-year-old girl with a third ventricle colloid cyst. She presented with prolonged headache, nausea, vomiting, and loss of visual acuity with bilateral papilledema. Computed tomography and MRI revealed severe biventricular hydrocephalus with transependymal periventricular fluid and a minimally enhancing cystic mass of the third ventricle. The patient was diagnosed with a colloid cyst and obstructive hydrocephalus, and endoscopic resection with ablation of the cyst remnant was performed. While attempting to extricate the cyst from the patient's head, control of the cyst was lost and the cyst fell into the lateral ventricle beyond the surgeon's view. Postoperative imaging showed that the cyst had settled in the right occipital horn. After 3 years of follow-up, imaging suggests growth of the cyst in its new position without necrosis or displacement on prone imaging.
Apple pomace silage ethanol intake and its effect on sheep
Authors: Islam S , Islam MN , Matsuzaki M
Published: March 2015

Two experiments were undertaken to investigate the feeding effect of alcoholic apple pomace silages (APSs) on performance traits, ruminal pH and blood variables in sheep. In experiment 1, four ewes were fed alfalfa hay cube and either APS (ethanol content was 33.4 g /kg DM) or concentrate (control) at a ratio of 30:70 of TDN requirement for maintenance and daily 100g gain in a 2×2 crossover design over two 35-day periods. Total body weight gain was higher in control treatment. No significant treatment effect was observed for TDN intake and ruminal pH. Plasma concentrations of ethanol, lactate and ?-hydroxybutyrate (BHBA) were increased after feeding APS. Plasma insulin, glucose, glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) were not significantly differ between the treatments. The area upper or under curves (AUCs)of plasma ethanol and BHBA were greater and lactate was tended to greater in APS treatment. In experiment 2, low and high ethanol contained APSs (L-APS, 44.1g and H-APS, 66.9 g of ethanol/kg DM) were compared in the same design (Experiment 1). No significant treatment effect was observed for body weight gain and TDN intake. Pre-feeding ruminal pH was lower in L-APS treatment. Insulin concentration was slightly higher in L-APS treatment. However, no significant treatment effect was detected for other variables. According to the consistent increase in plasma ethanol, lactate and BHBA, and the plasma AUCs response of ethanol, lactate and BHBA after feeding of alcoholic-fermented APSs, it would be concluded that APS ethanol consumption affect the post prandial blood metabolism as well as influenced the plasma lactate and BHBA concentrations in the blood.DOI: http://dx.doi.org/10.3329/bjas.v43i3.21655 Bang.

Published: March 2015

Portal hypertension is pathologic increase in portal venous pressure, with diversion of portal blood to the systemic circulation. The study was directed to measure as well as to compare the diameters of splenic, superior mesenteric and portal veins with their variation with respiration in normal subjects and in patients with portal hypertension. An analytic type of cross-sectional study was conducted at Radiology and Imaging Department of BIRDEM, Shahbag, Dhaka for one year (2011-12) among purposively selected 59 study subjects with chronic liver disease and portal hypertension, and 45 individuals without liver disease. Transabdominal ultrasonograpy of hepatobiliary system was carried out using computed sonography system with multiple probes having multiple frequency depending on physical built of the subjects. The diameters of selected veins were measured in the course of expiration and deep inspiration. In all control subjects, diameter variations of splenic vein and superior mesenteric vein were noted in the phases of respiration, the diameters increased during deep inspiration and decreased during deep expiration mean diameter and standard deviation of splenic vein and superior mesenteric vein were 6.95 ± 1.75 mm and 8.77 ± 2.06 mm respectively and during expiration they were 4.45 ± 1.24 mm and 5.66 ± 1.41 mm respectively. The difference in deep inspiratory and expiratory diameters had high statistical significance (p<0.0001). Patients with portal hypertension diameter variation with breathing at the level of splenic and superior mesenteric veins was observed only in 5 (9.47%) cases. Diminished response of splenic and superior mesenteric veins with respiration in transabdominal ultrasonography is an indicator of portal hypertension.
