Improved Detection of the First-Order Region for Direction-Finding HF Radars Using Image Processing Techniques
Authors: Kirincich Anthony 
Published: April 2017

AbstractFor direction-finding high-frequency (HF) radar systems, the correct separation of backscattered spectral energy due to Bragg resonant waves from that due to more complex double-scattering represents a critical first step toward attaining accurate estimates of surface currents from the range-dependent radar backscatter. Existing methods to identify this “first order” region of the spectra, generally sufficient for lower-frequency radars and low-velocity or low-surface gravity wave conditions, are more likely to fail in higher-frequency systems or locations with more variable current, wave, or noise regimes, leading to elevated velocity errors. An alternative methodology is presented that uses a single and globally relevant smoothing length scale, careful pretreatment of the spectra, and marker-controlled watershed segmentation, an image processing technique, to separate areas of spectral energy due to surface currents from areas of spectral energy due to more complex scattering by the wave field or background noise present. Applied to a number of HF radar datasets with a range of operating frequencies and characteristic issues, the new methodology attains a higher percentage of successful first-order identification, particularly during complex current and wave conditions. As operational radar systems continue to expand to more systematically cover areas of high marine traffic, close approaches to ports and harbors, or offshore energy installations, use of this type of updated methodology will become increasingly important to attain accurate current estimates that serve both research and operational interests.

Published: April 2017

Abstract
The variability of the North Atlantic Oscillation (NAO) is a key aspect of Northern Hemisphere atmospheric circulation and has a profound impact upon the weather of the surrounding landmasses. Recent success with dynamical forecasts predicting the winter NAO at lead times of a few months has the potential to deliver great socioeconomic impacts. Here, a linear regression model is found to provide skillful predictions of the winter NAO based on a limited number of statistical predictors. Identified predictors include El Niño, Arctic sea ice, Atlantic SSTs, and tropical rainfall. These statistical models can show significant skill when used to make out-of-sample forecasts, and the method is extended to produce probabilistic predictions of the winter NAO. The statistical hindcasts can achieve similar levels of skill to state-of-the-art dynamical forecast models, although out-of-sample predictions are less skillful, albeit over a small period. Forecasts over a longer out-of-sample period suggest there is true skill in the statistical models, comparable with that of dynamical forecasting models. They can be used both to help evaluate and to offer insight into the sources of predictability and limitations of dynamical models.
Feline urine metabolomic signature: characterization of low-molecular-weight substances in urine from domestic cats
Authors: Rivera-Vélez Sol-Maiam , Villarino Nicolas F 
Published: April 2017

Objectives This aim of this study was to characterize the composition and content of the feline urine metabolome. Methods Eight healthy domestic cats were acclimated at least 10 days before starting the study. Urine samples (~2 ml) were collected by ultrasound-guided cystocentesis. Samples were centrifuged at 1000 × g for 8 mins, and the supernatant was analyzed by gas chromatography/time-of-flight mass spectrometery. The urine metabolome was characterized using an untargeted metabolomics approach. Results Three hundred and eighteen metabolites were detected in the urine of the eight cats. These molecules are key components of at least 100 metabolic pathways. Feline urine appears to be dominated by carbohydrates, carbohydrate conjugates, organic acid and derivatives, and amino acids and analogs. The five most abundant molecules were phenaceturic acid, hippuric acid, pseudouridine phosphate and 3-(4-hydroxyphenyl) propionic acid. Conclusions and relevance This study is the first to characterize the feline urine metabolome. The results of this study revealed the presence of multiple low-molecular-weight substances that were not known to be present in feline urine. As expected, the origin of the metabolites detected in urine was diverse, including endogenous compounds and molecules biosynthesized by microbes. Also, the diet seemed to have had a relevant role on the urine metabolome. Further exploration of the urine metabolic phenotype will open a window for discovering unknown, or poorly understood, metabolic pathways. In turn, this will advance our understanding of feline biology and lead to new insights in feline physiology, nutrition and medicine.

Published: April 2017

The emplacement of igneous intrusions into sedimentary basins mechanically deforms the host rocks and causes hydrocarbon maturation. Existing models of host-rock deformation are investigated using high-quality 3D seismic and industry well data in the western Møre Basin offshore mid-Norway. The models include synemplacement (e.g., elastic bending-related active uplift and volume reduction of metamorphic aureoles) and postemplacement (e.g., differential compaction) mechanisms. We use the seismic interpretations of five horizons in the Cretaceous-Paleogene sequence (Springar, Tang, and Tare Formations) to analyze the host rock deformation induced by the emplacement of the underlying saucer-shaped Tulipan sill. The results show that the sill, emplaced between 55.8 and 54.9 Ma, is responsible for the overlying dome structure observed in the seismic data. Isochron maps of the deformed sediments, as well as deformation of the younger postemplacement sediments, document a good match between the spatial distribution of the dome and the periphery of the sill. The thickness [Formula: see text] of the Tulipan is less than 100 m, whereas the amplitude [Formula: see text] of the overlying dome ranges between 30 and 70 m. Spectral decomposition maps highlight the distribution of fractures in the upper part of the dome. These fractures are observed in between hydrothermal vent complexes in the outer parts of the dome structure. The 3D seismic horizon interpretation and volume rendering visualization of the Tulipan sill reveal fingers and an overall saucer-shaped geometry. We conclude that a combination of different mechanisms of overburden deformation, including (1) elastic bending, (2) shear failure, and (3) differential compaction, is responsible for the synemplacement formation and the postemplacement modification of the observed dome structure in the Tulipan area.
The virtues of virtual reality in exposure therapy
Authors: Gega Lina 
Published: April 2017

SummaryVirtual reality can be more effective and less burdensome than real-life exposure. Optimal virtual reality delivery should incorporate in situ direct dialogues with a therapist, discourage safety behaviours, allow for a mismatch between virtual and real exposure tasks, and encourage self-directed real-life practice between and beyond virtual reality sessions.

Published: April 2017

Silk sericin is a family of water-soluble proteins extracted from the silkworm cocoon. Studies have been attempted to recycle the sericin waste sericulture to develop value-added products in biomedical, pharmaceutical, cosmetic and food industries. Thus, increased production of sericin-containing wastewater from sericulture is predicted soon.Â In this study, some of the separation methods of sericin from silk waste water solution also extracted sericin characteristics have been investigated by FTIR. This study has determined antibacterial action of sericin in E. coli and Micrococcus luteus samples and illustrated sericin capacity as an antibacterial factor by confirming sericin on bacterial growth. Results of this study indicated discretion possibility of sericin from silk wastewater. Extracted sericin value depends on temperature and time. Characteristics of nonwoven textile coated by sericin had represented increasing of tensile and bending length and also showed that sericin with high concentration had preventive capacity of Micrococcus luteus bacterial on nonwoven textile.

<div class="page" title="Page 1"><div class="layoutArea"><div class="column">Attractive work has been defined as a job position which an individual wants, where the employee experiences job stability and where employee identification and dedication are fostered. The present study is aimed at increasing knowledge about attitude changes to work during young people’s transition from school to work-life. A closed cohort, consisting of 225 pupils from graduating classes in 10 upper secondary schools in Sweden, was studied. The most significant result was found in the pupils’ expectations regarding work attractiveness while they were still attending school and in the subsequent year, after they had finished school. During school attendance, there were no differences between the groups, while those who did not find employment after school greatly reduced their demands regarding attractive work.Those who managed to get a job maintained the same level of expectation as during their school years, in terms of requirements for an attractive job. </div></div></div>
Hospital Mergers in Norway: Employee Health and Turnover to Three Destinations

<div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p><span>This article investigates the probability of turnover to three destinations following hospital merg- ers: within the hospital sector, out of the hospital sector, and out of work. It is hypothesized that mergers increase turnover to nonemployment among employees with poor health and increase turnover to employment outside of the hospital sector among healthy employees. Discrete-time survival analyses show that mergers increase turnover within the hospital sector for all employ- ees, regardless of health. Turnover to other sectors and out of work does not increase. Possible explanations for the limited turnover out of the sector associated with mergers are aspects of the Norwegian labor market such as the institution of employee participation, low unemployment, and labor shortages within hospitals. </span></p></div></div></div>

Motive Factors of B.Ed Student Teachers for Choosing Teaching as their Calling
Authors: Sheeba K. 
Published: April 2017

<div><p><em>It is obvious that quality of teaching force is not governed only by the qualification, pedagogical knowledge and teaching skill of teachers, but also their enthusiasm, motivation, dedication and commitment in teaching. Student teachers have a substantial impact on the education of future generations. In order for a system of teacher education to be effective, it needs to recognize and build on the characteristics and motivations that student teachers bring with them when they enter teacher education program after their completion of graduation or post graduation. Holistic teacher building is necessary and therefore teacher education needed more emphasis than mere training by high positive motivation of the student teachers for choosing the teaching as their calling. The data for the present study were collected from a population of student teachers. In the present study, Survey Method is employed to describe and interpret. The sample size chosen for B.Ed., student teachers are 500 (250 Male and 250 Female) of the Pudukkottai District, Tamil Nadu, India. The findings revealed that female student teachers have manifested significantly higher level in all the selected variables when compared to their counter parts. The independent variables such as positive and negative emotion, altruism, moral value, teacher's attitude and personal and social influence correlate significantly with motivation positively. The coefficient of determination R square measures the goodness-of-fit with the value of 0.249 and this means that the independent variables contributes to the extent of 24.9% to motivation and it is significant at 1% level. </em></p></div>
Intractable hiccup cured by anaesthesia
Authors: Palte Howard D , Bahr Albert , Srur Lana 
Published: April 2017

SummaryHiccups (singultus) are paroxysmal involuntary contractions of the diaphragm and external intercostal muscles that are terminated by abrupt closure of the glottis, and result in the production of a characteristic sound. Aside from physical and psychological distress, prolonged hiccups produce sleep and alimentary disorders. During ophthalmic surgery, hiccup‐induced head movements are troublesome for the surgeon, and expose the patient to risk of unexpected eye injury and poor surgical outcome. We describe anaesthesia in a patient with intractable, therapy‐resistant hiccup of protracted duration (18 yr) scheduled for cataract extraction. In this case, general anaesthesia (without neuromuscular blocking agents) successfully inhibited the hiccup reflex arc and induced a sustained relief of symptoms. It is a reminder that not all hiccups derive from diaphragmatic stimulation, and that general anaesthesia may offer relief in hiccup mediated via central mechanisms.

Published: April 2017

Background: The increasing prevalence of adolescents obesity in the last decade have an impact on the increased prevalence of adolescents metabolic syndrome (MetS). Diet quality is one of the determining factors in the incidence of adolescents obesity, so it can also be a factor for MetS.Objective: To analyze the relationship between diet quality and MetS risk factors in obese adolescents.Method: A cross-sectional study was conducted on the 57 obese students in 7th and 8th grades of Nasima and Kesatrian Junior High School in Semarang. Blood pressure (BP) and waist circumference (WC) measurements, as well as blood samples for measurement of fasting blood glucose (FBG), triglyceride (TG) and HDL cholesterol (HDL-C), were conducted to determine the number of risk factors experienced by the subject. Diet quality was measured through assessment of food consumption using a food frequency questionnaire (FFQ). Pearson and Spearman's test was used to determine the correlation between diet quality and MetS risk factors.Results: The majority of obese adolescents (96.5%) had a low-quality of diet. There were 31.6% subjects experienced pre-metabolic syndrome and 68.4% had MetS, with the prevalence of MetS, was higher in male subjects. The diet quality, variety, adequacy scores and fiber intake of the pre-metabolic syndrome group were higher than MetS group. Variety and adequacy scores had significant negative correlation with TG (r = -0.374, p=0.004; r = -0.357, p=0.006, respectively). There was no significant relationship between diet quality score and the number of MetS risk factors (p=0.538), although they had a negative correlation (r = -0.083).Conclusion: Prevalence of pre-metabolic syndrome and MetS was 31.6% and 68.4%. Though there was no significant relationship, diet quality had a negative correlation with the number of MetS risk factors. Variety and adequacy scores had a significant relationship with triglyceride levels.

Background: Recently, obesity has become health problem which was frequently associated with an increased occurrence of non-communicable diseases. The prevalence of obesity has been increasing in both developed and developing countries. The increasing prevalence of obesity was marked by a shift in eating pattern composition containing high fat, cholesterol, but low in fiber such as consumption of fast food and soft drinks. The imbalance of nutrient intake was one of the risk factors for the emergence of obesity in adolescents. Obesity in adolescents at risk of becoming obese in adulthood and potentially can lead to cardiovascular and metabolic diseasesObjective: This study aimed to find out the prevalence of obesity and to investigate risk factors for energy intake and frequency of consumption of fast food and soft drinks on the incidence of obesity in high school students in Pontianak.Method: This research was an observational study which involves case-control design. The samples in this study are 160 students consisting of 80 obese high school teenagers and 80 non-obese high school teenagers. The choice for a subject of research used proportional stratified random sampling. Measurement of obesity status subject was taken by the measurement of weight and height based on the reference standard WHO / NCHS. It also involves data intake of fast food and soft drinks based on interviews with SQFFQ. Data were analyzed by chi-square test, t-test, and logistic regression.Results: The prevalence of obesity in high school teenagers in Pontianak was 9.29%. The bivariate test result showed no association between total energy intake of fast food and obesity (p<0.05; OR=2.27; 95% CI: 1.12-4.64). The relationship between the consumption of modern energy intake of fast food, fast food and soft drink with the local obesity was not statistically significant (p>0.05). There was a relationship between the frequency of total fast food and of the local fast food consumption with obesity (p<0.05; OR=2.03; 95% CI: 1.03-4.00), (p<0.05; OR=2.63; 95% CI: 1.33-5.25). The relationship between the frequency of fast food consumption in total modern fast food and soft drinks and obesity was not statistically significant (p>0.05). Multivariable analysis showed that the total energy intake was the most dominant factor to the onset of obesity (p<0.05; OR=5.27; 95% CI: 1.64-16.97).Conclusion: Consumption of fast food was a risk factor for obesity in high school teenagers in Pontianak. On the other hand, soft drink consumption did not become the risk factor for obesity in teens high school in Pontianak.
Política Organizacional Percebida e Incidência de Turnover dos Funcionários: Um Estudo Longitudinal na Nigéria

Published: April 2017

Although prior research has demonstrated that perceived organizational politics were positively related to employee turnover intention, however, little is known about possible causal explanations for the relationship between the two variables. To address this gap, a longitudinal design was employed to examine the relationship between perceived organizational politics and employee turnover intention with data collected over a two-year time period. Specifically, one hundred and seventy five Registered Nurses from government hospitals in Nigeria completed measures of perceived organizational politics and employee turnover intention at 2 times 16 months apart. There was empirical evidence, based on results of longitudinal regression analyses to support either the hypothesis that perceived organizational politics increases employee turnover intention or the hypothesis that employee turnover intention lead to organizational politics. However, employee turn over intention. and perceived organizational politics were found to change instantaneously. Implications of the results are discussed
POLA PEMANFAATAN DAERAH PENANGKAPAN IKAN UNTUK MEREDUKSI KONFLIK PERIKANAN TANGKAP DI PERAIRAN UTARA ACEH

Published: April 2017

Konflik perikanan tangkap di perairan Utara Aceh merupakan persoalan konflik yang sedang terjadi sejak tahun 2005 sampai 2015. Konflik perikanan tangkap secara umum terjadi akibat sumberdaya ikan yang semakin berkurang sehingga terjadi persaingan yang tidak sehat dalam memperebutkan sumberdaya pada daerah penangkapan ikan yang sama. Tujuan dari penelitian ini adalah menganalisis faktor-faktor penyebab dan dampak konflik perikanan tangkap serta menentukan pola pemanfaatan daerah penangkapan ikan untuk mereduksi konflik. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dan AHP (Analitycal Hierarchy Process). Hasil analisis menunjukan bahwa faktor-faktor penyebab konflik perikanan tangkapan di perairan Utara Aceh adalah penggunaan cahaya lampu pada purse seine, perebutan daerah penangkapan ikan, penggunaan bom ikan, penggunaan trawl, pemutusan rumpon, dan illegal fishing. Dampak yang dihasilkan dari konflik perikanan tangkap adalah tergganggunya habitat sumberdaya ikan, menurunnyan hasil tangkapan dan pendapatan nelayan tradisional serta pertikaian antar nelayan di daerah penangkapan ikan yang diperebutkan. Pola pemanfaatan yang dapat dikembangkan adalah (1) memberi perhatian dominan terhadap aspek biologi/SDI dalam setiap tindakan pemanfaatan, (2) meminimalisir terjadinya pemutusan rumpon (konflik utama), (3) menerapkan strategi penggelolaan dengan urutan prioritas: mediasi, arbitrase, negosiasi dan ganti rugi.
