HSI may be advantageous over near infrared spectroscopy (NIRS) as it scans entire samples, which enables compositional gradients and sample heterogenicity to be visualised and analysed. This study was a preliminary investigation to compare the performance of HSI with that of NIRS for quality measurements of ground samples of Australian wheat and to identify the most important spectral regions for predicting carbon (C) and nitrogen (N) concentrations. In total, 69 samples were scanned using an NIRS (400–2500 nm), and two HSI cameras operated in Citation: Tahmasbian, I.; Morgan, 400–1000 nm (VNIR) and 1000–2500 nm (SWIR) spectral regions. Partial least square regression N.K; Hosseini Bai, S.; Dunlop, M.W; (PLSR) models were used to correlate C and N concentrations of 63 calibration samples with their Moss, A.F Comparison of spectral reflectance, with 6 additional samples used for testing the models. -

These constructs provide insight on the phenome of schizophrenia and show how pathway-phenotypes mediate the effects of genome X environmentome interactions on the symptomatology/phenomenology of schizophrenia. -

Among the surveys conducted by the NCES, several pertain to postsecondary schooling and outcomes and are of interest to higher education researchers. These include Beginning Postsecondary Students (BPS), Baccalaureate and Beyond (B&B), National Postsecondary Student Aid Study (NPSAS), the National Study of Postsecondary Faculty (NSOPF), and the Integrated Postsecondary Education Data Set (IPEDS). With the exception of IPEDS, these surveys are conducted using complex survey designs, involving stratification, clustering, and unequal probabilities of case selection. Researchers analyzing these data must take the complex sampling designs into account in order to estimate variances accurately. Novice researchers and doctoral students, particularly those in colleges of education, will likely encounter issues surrounding the use of complex survey data for the first time if they undertake to analyze NCES data. Doctoral programs in education typically have minimal requirements for the study of statistics, and statistical theories are usually learned based on the assumption of a simple random sample. -

BAIDEN Signature: ........................................................... Date: ................................................................... i ABSTRACT Mining activities are undertaken in many parts of the world where mineral deposits are found. In developing nations such as Ghana, the activity is done both legally and illegally, often with very little or no supervision, hence much damage is done to the water bodies where the activities are carried out. This study sought to assess the social impacts of illegal gold mining activities at Dunkwa-On-Offin, the capital town of Upper Denkyira East Municipality in the Central Region of Ghana. The main objectives of the research are to identify factors that trigger illegal mining; to identify social effects of illegal gold mining activities on inhabitants of Dunkwa-on-Offin; and to suggest effective ways in curbing illegal mining activities. Based on the approach to data collection, this study adopts both the quantitative and qualitative approach. -

O. Box 249, Holeta, Ethiopia. 2Department of Plant Sciences, College of Agriculture and Veterinary Science, Ambo University. P. O. Box 19, Ambo, Ethiopia. Received 13 February, 2019; Accepted 11 April, 2019 The objectives of this study were to evaluate released Ethiopian bread wheat varieties for yield stability using the GGE biplot method and identify well adapted and high-yielding genotypes for the highland environments of South-western Ethiopia. Twenty five varieties were evaluated in a randomized complete block design with three replications at Dedo and Gomma during the main cropping season of 2016 and at Dedo, Bedelle, Gomma and Manna during the main cropping season of 2017, generating a total of six environments in location-by-year combinations. Combined analyses of variance for grain yield indicated highly significant (p<0.001) mean squares due to environments, genotypes and genotype-by- environment interaction. Yield data were also analyzed using the GGE (that is, G, genotype + GEI, genotype-by-environment interaction) biplot method. Environment explained 73.2% of the total sum of squares, and genotype and genotype X environment interaction explained 7.16 and 15.8%, correspondingly. -
The Association Between Four Scoring Systems and 30-Day Mortality Among Intensive Care Patients with Sepsis
www.nature.com/scientificreports OPEN The association between four scoring systems and 30‑day mortality among intensive care patients with sepsis: a cohort study Tianyang Hu 1,4, Huajie Lv2,4 & Youfan Jiang3* Several commonly used scoring systems (SOFA, SAPS II, LODS, and SIRS) are currently lacking large sample data to confrm the predictive value of 30‑day mortality from sepsis, and their clinical net benefts of predicting mortality are still inconclusive. The baseline data, LODS score, SAPS II score, SIRS score, SOFA score, and 30‑day prognosis of patients who met the diagnostic criteria of sepsis were retrieved from the Medical Information Mart for Intensive Care III (MIMIC‑III) intensive care unit (ICU) database. Receiver operating characteristic (ROC) curves and comparisons between the areas under the ROC curves (AUC) were conducted. Decision curve analysis (DCA) was performed to determine the net benefts between the four scoring systems and 30‑day mortality of sepsis. For all cases in the cohort study, the AUC of LODS, SAPS II, SIRS, SOFA were 0.733, 0.787, 0.597, and 0.688, respectively. The diferences between the scoring systems were statistically signifcant (all P‑values < 0.0001), and stratifed analyses (the elderly and non‑elderly) also showed the superiority of SAPS II among the four systems. According to the DCA, the net beneft ranges in descending order were SAPS II, LODS, SOFA, and SIRS. For stratifed analyses of the elderly or non‑elderly groups, the results also showed that SAPS II had the most net beneft. Among the four commonly used scoring systems, the SAPS II score has the highest predictive value for 30‑day mortality from sepsis, which is better than LODS, SIRS, and SOFA. -
