Early Detection and Intervention in Audiology

Implementation of early hearing detection and intervention (EHDI) is a significant challenge in the South African context, despite its documented benefits. South Africa, like other low and middle-income (LAMI) countries, is confronted with specific contextual realities. These include the lack of a government mandate for universal newborn hearing screening (UNHS), major resource constraints, a high burden of disease with which EHDI has to compete, and significantly poor social determinants of health. This chapter delib-erates on the various issues plaguing early detection in South Africa. It begins by describing the South African health care context and its challenges. This is followed by a more detailed and focused review of literature on the challenges around demand versus capacity and resources, the burden of disease, as well as research evidence on newborn hearing screening (NHS) in South Africa. A call for a ‘doing better with less’ approach is presented. Lastly, possible solutions and recommendations for hearing detection initiatives in the South African context are offered
The Validity and Reliability of the Turkish Version of MacArthur Competence Assessment Tool for Treatment Decision: Correlates of Competence in Schizophrenia Patients

Introduction: Informed consent is an indispensable condition of the clinical practice for the provision of health care. The main objective of this study is to translate the MacArthur competence assessment tool for treatment (MacCAT-T) into Turkish and evaluate the validity and reliability of the Turkish version in schizophrenia patients and healthy control subjects. Methods: In this cross-sectional study, 30 hospitalized schizophrenia patients and 25 healthy subjects were assessed with MacCAT-T, Mental Competence Evaluation Form for Assessment of Competency (MCEF), Positive and Negative Syndrome Scale, Beck Depression Inventory, Mini Mental State Examination, Wechsler Adult Intelligence Scale (WAIS) – Similarities subtest and the Schedule for Assessing the Three Components of Insight. Psychometric properties of MacCAT-T were examined by intra-class correlation coefficients and Cronbach’s alpha values. Results: Intra-class correlations ranged between 0.83 and 0.99 for four subscales of the tool. Cronbach alpha value of MacCAT-T was found 0.89. Severity of psychopathology and indices of insight were found to be negatively correlated with the subscales of the tool. WAIS-Similarities subtest scores were found to be positively correlated with understanding and reasoning subscales of MacCAT-T. Conclusion: The Turkish version of MacCAT-T is a valid and reliable instrument for Turkish patients. The severity of psychopathology, insight and executive functions were shown to be significantly related to the decision making capacity in patients with schizophrenia.
Impacts of phosphorus loads on the water quality and the proliferation of harmful cyanobacteria in Foum-Gleita Reservoir (Mauritania)

Excess phosphorus and nitrogen inputs into freshwater ecosystems is one of the main causes of expansion of harmful cyanobacterial blooms worldwide. This work was conducted to study the impacts of phosphorus leaching from the exploitation of phosphate mines present in the watershed of Foum-Gleita Reservoir (Mauritania) on the water quality and its major contribution to the proliferation of harmful cyanobacteria throughout the year. The physicochemical parameters, the occurrence and abundance of phytoplankton (including cyanobacteria), and the microcystins concentration were monitored monthly from September 2017 to August 2018. The relationships between limnological and biological variables were explored by using Pearson's correlation and forward stepwise multiple linear regression (MLR) analysis. Microcystins were detected by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Our results showed that this reservoir can be classified as hypereutrophic throughout the year and that Microcystis aeruginosa (M. aeruginosa) and Dolichospermum flos-aquae (D. flos-aquae) were dominant species during the rainy season (July-September), and only the congener microcystin-LR (MC-LR) was detected with a peak at 3.55 µg L−1. Pearson's correlation and MLR analysis showed that water temperature pH, phosphorus, nitrogen, and iron concentrations were the most important variables accounting for M. aeruginosa and D. flos-aquae abundance and MC-LR concentration. Our study provides new insight into the effects of moderate nitrogen concentrations on phytoplankton community composition with dominance of the cyanobacteria phylum in phosphorus-rich freshwater ecosystems.
Change point estimation in regression model with response missing at random

Abstract Based on the approach of left and right kernel smoothing with unilateral kernel function, we, in this paper, define estimators of change point and jump size in nonparametric regression model with response missing at random. It is shown that the change point estimator is n-consistent and converges to the smallest maximizer of one-dimensional bilateral compound Poisson process, the jump size estimator is asymptotically normal. A simulation study is conducted to investigate the finite sample behavior for the proposed methods.
Plume‐Induced Sinking of Intracontinental Lithospheric Mantle: An Overlooked Mechanism of Subduction Initiation?

Although many different mechanisms for subduction initiation have been proposed, only few of them are viable in terms of consistency with observations and reproducibility in numerical experiments. In particular, it has recently been demonstrated that intra‐oceanic subduction triggered by an upwelling mantle plume could greatly contribute to the onset and operation of plate tectonics in the early and, to a lesser degree, modern Earth. On the contrary, the initiation of intra‐continental subduction still remains underappreciated. Here we provide an overview of 1) observational evidence for upwelling of hot mantle material flanked by downgoing proto‐slabs of sinking continental mantle lithosphere, and 2) previously published and new numerical models of plume‐induced subduction initiation. Numerical modeling shows that under the condition of a sufficiently thick (>100 km) continental plate, incipient downthrusting at the level of the lowermost lithospheric mantle can be triggered by plume anomalies of moderate temperatures and without significant strain‐ and/or melt‐related weakening of overlying rocks. This finding is in contrast with the requirements for plume‐induced subduction initiation within oceanic or thinner continental lithosphere. As a result, plume‐lithosphere interactions within continental interiors of Paleozoic‐Proterozoic‐(Archean) platforms are the least demanding (and thus potentially very common) mechanism for initiation of subduction‐like foundering in the Phanerozoic Earth. Our findings are supported by a growing body of new geophysical data collected in various intra‐continental areas. A better understanding of the role of intra‐continental mantle downthrusting and foundering in global plate tectonics and, particularly, in the initiation of “classic” ocean‐continent subduction will benefit from more detailed follow‐up investigations.
Raman spectral analysis of the brainstem and responses of neuroglia and cytokines in whole-body gamma-irradiated rats after administration of aminothiol-based radioprotector GL2011

The search for an effective and non-toxic radioprotector is ongoing. We tested a novel, natural aminothiol-based radioprotector, GL2011, that was applied 30 min, 3 h or 6 h after the exposure of male albino Wistar rats to a 6.7 Gy mild dose of gamma radiation. The molecular signatures of radioprotection were investigated with Raman microspectroscopy of brainstem tissue samples. Morphological changes and activation of astrocytes and microglia were assessed by immunohistochemistry. Global markers of neuroinflammation were followed by ELISA to monitor blood plasma levels of proinflammatory (IL-6 and TNF-? ) and anti-inflammatory (IL-10) cytokines. A thirty-day follow-up determined survival of unprotected animals 37.5%. A survival increase was observed after radioprotection (75%, irrespective of the time of application). Raman spectra revealed a slightly deleterious effect of radiation on nucleic acids in surviving animals that was mitigated with the radioprotector, as GL2011 preserved the morphology of both astrocytes and microglia, with reduced microglial infiltration. Cytokine assessment revealed an immunomodulatory effect of the novel radioprotector. The overall results point out the positive effects of a single dose of GL2011 applied at different times. The molecular and cellular changes in the brainstem indicate that the radioprotector applied after radiation conferred better protection, which underlines its translation to cure radiation accidents.
Histopathological Characterization of Soft Palate in Brachycephalic Syndrome in Pugs: A Review of 12 Cases

Brachycephalic air way syndrome is defined as partial obstruction of upper airway of dogs and cats having shortened head due to selective breeding. Obstruction is due to anatomical abnormalities of stenoticnares, elongated soft palate, everted laryngeal saccules and hypoplastic trachea (Poncet et al., 2005). Surgical correction of the elongated soft palate has been reported since 1942 (Farquharson1942). Clinical signs include dyspnea, snoring, stridor, exercise intolerance, regurgitation, vomiting, cyanosis, syncope and collapse (Gruenheid et al., 2018) 80% of dogs with elongated soft palate were brachycephalic and was considered as one of the most common abnormality found in brachycephalic airway syndrome.

Sizing and Cost Minimization of Standalone Hybrid WT/PV/Biomass/Pump-Hydro Storage-Based Energy Systems

In this study, a standalone hybrid wind turbine (WT)/photovoltaic (PV)/biomass/pump-hydro-storage energy system was designed and optimized based on technical, economic, and environmental parameters to provide the load demand with an objective function of minimum cost of energy (COE). The constraints of the proposed approach are the loss of power supply probability, and the excess energy fraction. The proposed approach allows the combination of different sources of energy to provide the best configuration of the hybrid system. Therefore, the proposed system was optimized and compared with a WT/PV/biomass/battery storage-based hybrid energy system. This study proposes three different optimization algorithms for sizing and minimizing the COE, including the whale optimization algorithm (WOA), firefly algorithm (FF) and particle swarm optimization (PSO) and the optimization procedure was executed using MATLAB software. The outcomes of these algorithms are contrasted to select the most effective, and the one providing the minimum COE is chosen based on statistical analysis. The results indicate that the proposed hybrid WT/PV/biomass/pump-hydro storage energy system is environmentally and economically practical. Meanwhile, the outcomes demonstrated the technical feasibility of a pump-hydro energy storage system in expanding the penetration of renewable energy sources compared to other existing systems. The COE of the pumped-hydro storage hybrid system was found to be lower (0.215 $/kWh) than that with batteries storage hybrid system (0.254 $/kWh) which was determined using WOA at the same load demand.
Interacting in Japanese and English in the English as a Foreign Language Classroom

Due to recent directives from the Japanese government, high school English teachers in Japan are under increasing pressure to conduct their classes mostly in English. This study explored the attitudes of Japanese high school students toward the use of English in language classes to better determine when and how teachers may integrate English and Japanese into their lessons. The researcher conducted quantitative and qualitative research, including action research, with 12 participants to devise pedagogy that high school teachers in Japan could adopt and implement to make better and more authentic use of English in the classroom. The results suggest that most of the student participants favour more classroom English use for the purposes of improving their speaking and listening skills. Pedagogy implemented following the research comprised specific tasks that teachers can adopt in their English classes to increase L2 use. 日本政府の近年の方針により、日本の高校英語教員は授業をほぼ英語で行わなければならないという、増大するプレッシャーの下に置かれている。 本研究では、教師が授業で、いつ・どのようにして英語と日本語を使い分けるのが良いかをよりよく判断するために、英語使用に対する日本人高校生の態度を探究した。 本研究者は、12人の被験者を使って、日本の高校教師が、授業で英語をより適切かつ本格的に使用する目的で、適用および実行可能な教授法を考案するため、アクション・リサーチを含む定量的および定性的研究実施した。 研究結果は、参加した生徒たちの大半がスピーキングやリスニングスキル向上のために、教室内でより多くの英語の使用を好んだことを示している。 研究結果を反映し、第二言語使用を増やすため、英語の授業において教員が採用できる特定のタスクを含む教授法がアクション・リサーチとして用いられた。
209Bi NMR in Topologically Trivial and Nontrivial Half-Heusler Bismuthides

209Bi NMR experiments were performed for half-Heusler compounds ScPtBi, LaPdBi, and LaPtBi. The resonance shifts in these materials as well as in a few isostructural RTBi (R = Sc, Y, Lu; T = Pd, Pt) phases were revealed to correlate linearly with the calculated band inversion strength that characterizes topological character of the systems. On the contrary, commonly accepted relationship between the NMR shifts and the average nuclear charge was found to be violated.
Erosion Performance of Atmospheric Plasma Sprayed Thermal Barrier Coatings with Diverse Porosity Levels

Thermal barrier coatings (TBCs) prolong the durability of gas turbine engine components and enable them to operate at high temperature. Several degradation mechanisms limit the durability of TBCs during their service. Since the atmospheric plasma spray (APS) processed 7–8 wt. % yttria stabilized zirconia (YSZ) TBCs widely utilized for gas turbine applications are susceptible to erosion damage, this work aims to evaluate the influence of their porosity levels on erosion behavior. Eight different APS TBCs were produced from 3 different spray powders with porosity ranging from 14% to 24%. The as-deposited TBCs were examined by SEM analysis. A licensed software was used to quantify the different microstructural features. Mechanical properties of the as-deposited TBCs were evaluated using micro-indentation technique. The as-deposited TBCs were subjected to erosion tests at different angles of erodent impact and their erosion performance was evaluated. Based on the results, microstructure-mechanical property-erosion performance was correlated. Findings from this work provide new insights into the microstructural features desired for improved erosion performance of APS deposited YSZ TBCs.

Temporary turbine and reservoir level management to improve downstream migration of juvenile salmon through a hydropower complex

Developing management rules to improve downstream migration of salmon smolts in large hydropower plants is essential to limit mortality and migration delay. A 2-year telemetry study was conducted to assess the efficiency of temporary measures to enhance the safety and speed of juvenile salmon passage through the Poutès dam (Allier River, France). 124 smolts were tracked through the reservoir and downstream of the dam, during implementation of turbine modulation and/or shutdown during night and reservoir level lowering. Level lowering significantly reduced median residence time from 3.4 days to 4.4 hours. However, even with high spill during turbine modulation, the risk of smolt being drawn toward the turbines was increased at low reservoir level due to the site's configuration, greater proximity to the surface and weak repulsive effect of the rack. Moreover, results revealed that a substantial proportion of smolts can migrate during daytime and twilight during floods, even at the beginning of the migration period. Thus targeted turbine shutdown has a good potential to protect smolts, but implementation requires studies taking account of site specificities and a flexible approach.
Dyadic empathy in Polish samples: validation of the Interpersonal Reactivity Index for Couples

BACKGROUND Empathy as a multidimensional construct is considered a basis of satisfying intimate relationships. The role of other-oriented focus in empathizing with a partner has been highlighted. The Interpersonal Reactivity Index for Couples (IRIC) measures emotional and cognitive empathy displayed in the context of a romantic relationship and expressed towards the partner. PARTICIPANTS AND PROCEDURE A total sample of 2339 individuals in intimate relationships (including 1006 couples) participated in the research. Three studies are presented on adaptation of the IRIC to Polish in the context of participants’ emotional and relational functioning. RESULTS The two-factor structure of the measure was confirmed. However, the specific content of two factors was modified to better fit the data. A reliable and valid measure of empathic tendencies in couples has been obtained. Emotional dyadic empathic concern and cognitive dyadic perspective taking were associated with general emotional and cognitive empathy as well as with relationship satisfaction. Correlations with emotional contagion, stress and attachment were also explored. CONCLUSIONS The IRIC is a short, reliable and valid measure of empathic tendencies in couples to be easily implemented in research and practice. Personal traits of both partners should be seen as predictors or correlates of dyadic empathy. The presented research results might be applied to the design of interventions and programs increasing quality of romantic relationships.
In situ observation of the motion of ferroelectric domain walls in Bi4Ti3O12 single crystals

Five types of ferroelectric domain walls (DWs) are present in Bi4Ti3O12 single crystals (Ye et al., 2015). Here their motion was investigated in situ using transmission electron microscopy and optical microscopy. The motion of P(a)-90° DWs, P(a)-180° DWs and P(c)-180° DWs was observed through electron beam poling in a transmission electron microscope. The growth of new Ps(a)-180° nanodomains was frequently seen and they tended to nucleate at preexisting Ps(a)-90° DWs. Irregularly curved P(c)-180° DWs exhibit the highest mobility, while migration over a short range occurs occasionally for faceted Ps(a)-90° DWs. In addition, the motion of Ps(a)-90° DWs and the growth/annihilation of new needle-like Ps(a)-90° domains in a 20 µm-thick crystal were observed under an external electric field on an optical microscope. Most of the new needle-like Ps(a)-90° domains nucleate at preexisting Ps(a)-90° DWs and the former are much smaller than the latter. This is very similar to the situation for Ps(a)-180° domain switching induced by electron beam poling in a transmission electron microscope. Our observations suggest the energy hierarchy for different domains of Ps(c)-180° ≤ Ps(a)-180° ≤ Ps(a)-90° ≤ new needle-like Ps(a)-90° in ferroelectric Bi4Ti3O12.
A Novel Misalignment Tolerant Magnetic Coupler for Electric Vehicle Wireless Charging

The lateral misalignment for static electric vehicle (EV) wireless charging could be much larger than 100 mm if the parking assistance systems are unavailable. This article proposes a split flat solenoid coupler (SFSC) to significantly extend the lateral misalignment and reduce the copper and ferrite usage. To obtain a good balance among coupling, misalignment tolerance, and cost, an optimization method for SFSC is proposed where the size limitations and ferrite tile specifications are considered. The optimized SFSC is compared with two magnetic couplers recommended in SAE J2954 in terms of coupling coefficient and misalignment tolerance. To eliminate the impact of coil size and make the comparison fair, the quantified misalignment tolerance is introduced. The proposed SFSC provides much better misalignment tolerance than the recommended couplers. A 1000-W prototype is built to show the advantages of the proposed coupler. The output current keeps unchanged when the lateral misalignment is as high as 400 mm. A highest power transfer efficiency, from dc input to dc output, of 89.12% is achieved when the output power is 1000 W.
Diurnal rhythm of blood biochemical profile of sun exposed Martina Franca jacks in semitropical desert climate

Diurnal rhythm of blood biochemical profile was studied in adult and apparently healthy, male Martina Franca (Poitou) jacks (n=6). The jacks weighing between 270 to 350 kg were fed with standard ration for maintenance as per NRC (2007) from 10:00h to 14:00hr. The donkeys remained exposed to solar radiation. Blood was collected for biochemical parameters at 07:00h, 10:00h, 14:00h and 16:00h on 1st, 4th and 7th day in a seven day experimental period during October 2016 (heat stress period (HS), Thermal heat index (THI)=69.90 at7.00h and 80.14 at 14.00h) and on a single day in peak winter in December 2016 (control ‘C’, THI: 63.93 at 7.00h and 80.14 at 14.00h). Plasma albumin and globulin (g/dl) increased significantly on day 1 of HS from 07.00h to 14.00h & 16.00h. Plasma Lactate (mM/l) increased significantly at 14.00h & 16.00h as compared to 07:00h in both ‘HS’ and ‘C’. The lactate levels were significantly lower at the respective diurnal time points in period ‘C’. Urea (mg/dl) increased significantly (p< 0.05) at 14.00h & 16.00h when compared to its values at 07.00h & 10.00h on in ‘HS’. Maximum urea level was observed at 16.00h on day 1 of ‘HS’. During winter, although urea levels increased significantly at 10.00h, 14.00h & 16.00h from the values observed at 07.00h, the levels remained lower when compared to ‘HS’ at 14:00h and 16:00h. Similar trends were observed for plasma creatinine (mg/dl) which remained significantly higher in ‘HS’ than in ‘C’. The cholesterol decreased at 10.00h & 14.00h and again increased significantly (p
