Developing reflection through an ePortfolio-based learning environment: design principles for further implementation

ABSTRACT This article discusses the implementation of an ePortfolio-based learning environment with Bachelor of Education students. The intention was for the platform to be an agency for the development of reflection. The environment scaffolded reflection through (1) exemplars of good practice, (2) the opportunity for discussions and (3) activities to support the development of reflection. There were issues within the research around the introduction of the platform at the particular stage of the students’ degrees but the environment was successful in the provision of a teaching and learning platform. The findings provided design principles for a model to guide the development of similar learning environments including (1) the need for the ePortfolio platform to be embedded across the degree programme with (2) regular tasks for the students to complete that (3) have a clear purpose that the students are aware of and (4) utilise interaction patterns that mimic the structures of social media.
Maternal mortality by direct obstetric causes in an urban referral hospital: case of Boulmiougou District Hospital in Ouagadougou, Burkina Faso

Background: Complications during pregnancy and childbirth are the leading causes of death and disability for women of childbearing age. Objective of this study was to study maternal mortality of direct obstetric origin at the Boulmiougou district hospital from 2010 to 2014.Methods: This was a retrospective cross-sectional descriptive and analytical study of maternal deaths by direct obstetric cause at the maternity ward of Boulmiougou District Hospital during the period from January 1st 2010 to December 31st, 2014, i.e. 5 years.Results: The maternal mortality rate by direct obstetric cause of 147.68 maternal deaths per 100,000 live births. The average age of the patients was 27.09 years old. The direct causes of maternal death were hemorrhage (47.06%), hypertensive disorders (20.59%), infections (14.71%) and unsafe abortion (11.76%). Contributing factors to maternal deaths were delay in evacuation (47.06%) and delay in care (38.23%). Conclusions: Maternal mortality remains high in the Boulmiougou District Hospital. To effectively combat maternal mortality, it is important to focus on the continuous training of staff and the strengthening of the technical platform.
IDENTIFICATION OF F 2 AND F 3 SEGREGANTS OF FIFTEEN RICE CROSSES SUITABLE FOR CULTIVATION UNDER AEROBIC SITUATION

Genetic variability studies provide basic information on genetic parameters of the population based on which selection of genotypes and breeding strategy could be formulated for crop improvement. The estimates of heritability, coefficients of variability and genetic advance were computed in F2 segregating populations of the 15 crosses for 14 characters. The selected F2 plants were forwarded to generate F3 families during dry season under aerobic conditions. The estimates of phenotypic coefficients of variation (PCV) were high and moderate for days between flowering and maturity (11.3%), number of tillers (20.0%), number of panicles (23.4%), 100 grain weight (18.7%), panicle exertion (13.5%), panicle length (20.1%), leaf width (12.2%), straw weight (23.5%) and grain yield (36.2%) in different crosses. High estimates of heritability coupled with high and moderate genetic advance was observed for all the plant traits. Correlation analysis indicated that flowering time, plant height, number of tillers, number of panicles, grain length, grain width, panicle length and straw weight had exhibited significant positive association with grain yield plant. The correlation and regression coefficient between F2 and F3 generation for crosses MAS26 × IM88, OYC145 × MAS946-1 and IR64 × IM192 were significant for 50% flowering time, maturity time, plant height, productive tiller per plant, 100 grain weight, panicle length and grain yield. This indicated the effectiveness of selection for these characters.
Effect of Food Processing on Flavanols

The strong correlation between dietary habits and some chronic diseases have been reported in numerous studies. In recent years, compounds with functional properties that provide specific health benefits to human have become popular. Flavanols, a subgroup of phenolic compounds, are generally found in green tea, cocoa, coffee, red grapes and apples. These monomeric bioactives are known as potent antioxidants. During various food processes these compounds expose to certain thermal or mechanical treatments and biochemical reactions. All of these applications lead to reversible/irreversible alterations in the structure of flavanols. Mainly the conversions affect appearance and sensorial characteristics of foods. On the other hand, bioavailability of flavanols is also influenced depending on structural changes of monomeric units. In this review, the effect of prominent processing techniques on flavanol contents of several foods is discussed.
Autonomic nervous system function accessed by conventional and spectral analysis might be useful in terms of predicting retinal deterioration in persons with type 1 diabetes mellitus

Aims: To determine whether cardiac autonomic dysfunction represents a risk factor for diabetic retinopathy (DR) development and progression in persons with type 1 diabetes mellitus (T1DM). Methods: The study comprised 154 normoalbuminuric persons with T1DM divided into two groups according to the DR presence: one with and another without DR. Cardiovascular autonomic functioning was accessed by conventional and spectral data analysis. Student’s t-test and Fischer’s exact test were used to access between group differences. Cox’s proportional hazards regression analysis was used to examine the baseline variables predictive for development or progression of NPR 18 months after. Results: The group with DR had longer disease duration compared to the group witout DR (20 vrs 11.5 years, p<0.001), heart rate coefficient of variation (HRV-CV) at rest and during deep breathing, as well as its vagal nerve mediated modulation, were lower in participants with DR (p=0.001; 0.004 and <0.001, respectively). No difference in glycaemic control, lipid status or hypertension rate was observed. Twenty-one (13.36%) participants developed non proliferative DR or progressed to proliferative DR. For each increase in the HRV-CV of 1%, the 18 months risk from retinal deterioration was reduced by 33.4% and by 12.7% for the same HRV-CV increase during deep breathing while the increase of parasympathetic nerve activity output of 1 ms 2 results in 8.6% DR risk reduction. Conclusions: This study provides evidence that DR should not be considered merely a metabolic control manifestation and that HRV-CV might be the top predictor of retinal deterioration in normoabuminuric persons with T1DM.
5-1-2018 Models of Other-Regarding Preferences and Redistribution

In spite of the increasing popularity of comparative work on other-regarding preferences, the theoretical implications of different models of altruism are not always fully understood. This paper explores different theoretical approaches to altruism and elucidates their implications, paying particular attention to models of redistribution preferences where inequality explicitly triggers altruistic other-regarding motives for redistribution. While the main contribution of the paper is to clarify these theoretical models, we also illustrate the importance of having these distinct implications by analyzing some Western European data to compare among them. We draw on individual-level data from the European Social Survey (ESS) fielded between September 2002 and December 2013. ∗University at Buffalo School of Law, mdimick@buffalo.edu †Department of Politics & IR and Nuffield College, University of Oxford david.rueda@politics.ox. ac.uk ‡Department of Political Science, Duke University, mail@daniel-stegmueller.com
UNDERSTANDING THE INNOVATIVE BEHAVIOR OF FIRMS : THE EFFECT OF PERSISTENCE DECISIONS ON INNOVATION PERFORMANCE

The study of the dynamic patterns of behavior has recently attracted the attention of scholars studying the investments in R&D of firms and the establishment of collaborative agreements. Surprisingly, although extant research has acknowledged that investments in R&D could potentiate the establishment of collaborative agreements, the literature has no analyzed the impact on innovation performance that persistence in these two activities have, both individually and jointly. In this paper, we analyze the effect that persistence in R&D and persistence in collaboration have on innovation performance, and the moderating effect that persistence in R&D has on the relationship between persistence in collaboration and innovation performance. We argue that both activities have a positive impact on innovation performance and that persistence in R&D potentiates the relationship between persistence in collaboration and innovation performance. To test empirically these hypotheses, we will use a large panel of Spanish innovating firms for the period 2005-2013.
Synthesis of Ag-TiO 2 nanomaterial for treatment of organic pollutants under visible light

In this study, the sol-gel synthesis method was employed for the preparation of silver-doped TiO2 nanomaterial from potassium fluorotitanate and silver nitrate. The silver can be incorporated by direct calcination of the sol-gel material decomposing silver nitrate to silver. The visible light absorption ability of AgTiO2 nanoparticles was investigated by means of UV-Vis measurement. Based on the UV-Vis spectra, the absorption in the visible light of the Ag-TiO2 was found to be improved and was shifted to longer wavelength. The XPS spectra indicated that the elements detected were titanium, oxygen, and silver. Titanium and oxygen presented as Ti 4+ and O 2− and silver Ag existed in Ag (0) form. It is attributed to the fact that the silver is homogeneously dispersed throughout the material. The experimental results showed that the photocatalytic efficiency of Ag-TiO2 was better than prepared TiO2 under the same conditions for the photodegradation of methylene blue.
A Comparative Study of Red Cell Histogram along with CBC parameters and Peripheral Blood Smear in Various Anemias

Background: Visual scanning of histogram gives a good sense of range, size, shape and other salient features of red cell morphology. Automated haematology analyzers are already an integral part of routine purpose diagnostic laboratory setup. So, we planned a study to evaluate utility of automated RBC parameter in evaluation and diagnosis of anaemia. Objectives: (1) to interpret the RBC histogram in anemic patients (2) To compare automated histogram patterns and CBC parameters with morphological feature seen on peripheral smear examination with special reference to RDW. Methodology: It was a cross sectional study and conducted at Central Diagnostic Laboratory at RNT medical College, Udaipur. Blood sample of 600 anemic patients were selected using systematic random sampling and data were analysed using Epi-info 7.0 software by proportion, mean and Pearson’s correlation. ResultsOut of 600 cases, 402 cases showed concordant typing of anemia with automated analyzer and using peripheral smear examination. 198 cases showed discordant typing, which typed correctly with peripheral smear examination. MCV and RDW were positively moderately correlated with each other in the whole sample and also in Iron deficiency as well as in megaloblastic anemia. MCV and RDW were positively and mildly correlated in mixed deficiency and in anemia of chronic disease. In a similar way MCH and RDW were positively and mildly correlated in all the etiological groups of anemia. Other haematological parameters like Hb, HCT, RBC count and Platelet counts were negatively correlated with RDW. All these correlations were statistically significant. ConclusionThough automated analyzer reduces overall workload by its advances of graphical representation, it should be confirmed by microscopy.
Clinical aspects and the origin of sepsis patients treated at a university hospital

Universidade Estadual de Londrina, Londrina, PR, Brazil. Confl icts of interest: none. Abstract Objective: To characterize the clinical aspects, severity and mortality of sepsis patients treated in the urgency and emergency departments of a tertiary hospital, relating them to the health services of origin, where initial care was performed. Methods: Cross-sectional, quantitative study with sepsis patients, treated in the urgency and emergency departments of a tertiary university hospital. Results: Of the 225 eligible patients, 115 (51.1%) were hospitalized with sepsis; of these, 63.5% were referred from other services. Among patients from other services, the development of septic shock and the need for mechanical ventilation was signifi cantly more frequent. Patients admitted to the sepsis study hospital had greater adherence to the 3-hour package of the Surviving Sepsis Campaining-2016. There was no difference between the mortality of those admitted for having sepsis and those who developed sepsis in the study hospital. However, 60.4% of the patients died, 63.2% of whom came from other services. Conclusion: More than half of the patients hospitalized with sepsis come from other health services. they presented a greater degree of severity and required more therapeutic interventions. However, there was no difference in mortality rates.
Gblur JPEG Large ranking dataset Siamese Network RankingShared weights Small IQA dataset Scores : 36

We propose a no-reference image quality assessment (NR-IQA) approach that learns from rankings (RankIQA). To address the problem of limited IQA dataset size, we train a Siamese Network to rank images in terms of image quality by using synthetically generated distortions for which relative image quality is known. These ranked image sets can be automatically generated without laborious human labeling. We then use fine-tuning to transfer the knowledge represented in the trained Siamese Network to a traditional CNN that estimates absolute image quality from single images. We demonstrate how our approach can be made significantly more efficient than traditional Siamese Networks by forward propagating a batch of images through a single network and backpropagating gradients derived from all pairs of images in the batch. Experiments on the TID2013 benchmark show that we improve the state-of-theart by over 5%. Furthermore, on the LIVE benchmark we show that our approach is superior to existing NR-IQA techniques and that we even outperform the state-of-the-art in full-reference IQA (FR-IQA) methods without having to resort to high-quality reference images to infer IQA.
Sains Humanika The Mediating Impact of Occupational Stress on Leadership Style and Job Performance

The aim of this study is to evaluate the intervening effect of occupational stress on leadership style and job performance. Using a proportionate stratified random sampling, questionnaire survey was employed and distributed to the employees of utility industries in Malaysia and a total of 175 employees participated. The regression results showed that: (1) it is partially supported for a significant association between leadership style and job performance, (2) it is partially supported for a significant association between leadership style and occupational stress. Contrary to expectation, there have no intervening effect of occupational stress on the association between leadership style and job performance. One probable explanation could be that the occupational stress level itself was found low among respondents. Respondents highlighted they have the work-related stress but perhaps due to most of them are healthy, educated, lack in working experience, or due to they are yuppies, (that is indicating they are in young age, ambitious, and hunger for challenging tasks), they did not perceive the stress as the actual stress as felt by the other group of age. Thus, the result suggested that occupational stress as an intervening role among the yuppies group is not a relevant issue in discussing job performance. In future study, other factors should be considered to increase about the explanation on job performance.

EFFECT OF WEED MANAGEMENT PRACTICES ON GROWTH AND YIELD OF PIGEONPEA [ CAJANUS CAJAN ( L . ) MILLSP . ]

Pigeonpea [Cajanus cajan (L.) Millsp. ] is one of the important pulse crops in the world and widely grown throughout the tropics in Africa, America, Australia, Hawaii, West Indies, Srilanka and China. Pigeonpea is commonly known as red gram, tur or arhar and it is the fifth prominent legume crop in the world and second in India after chickpea occupying 14.5 per cent of area and 15.5 per cent of total pulse production (Mishra et al., 2011). In India, it occupies an area of 3.90 m ha with a production of 3.38 m t and average productivity of 871 kg per ha which is far below the world’s average productivity (1049 kg ha-1). In Karnataka, it occupies an area of 0.66 m ha with a production of 0.63 m t and average productivity is 950 kg per ha (Anon., 2013).
Impact of pesticides on Trichoderma harzianum and on its possible antagonistic activity against Fusarium oxysporum under In vitro conditions

In vitro study was conducted to evaluate the effect of fourteen selected pesticides including six fungicides, four insecticides and four herbicides on the growth of a local strain of Trichoderma harzianum and on possible antagonistic activity of the treated fungus against Fusarium oxysporum. For compatibility study, each pesticide was tested at seven concentrations using poisoned food technique. While for the antagonistic activity study, treated T. harzianum was tested against F. oxysporium using dual culture technique under laboratory conditions. Significant differences were observed between the pesticides and the concentration used in the inhibition of mycelial growth and the inhibition increased with concentration increase. None of the concentrations tested of wettable sulphur, copper oxychloride, diazinon, cypermethrin, oxamyl, tribenuron-methyl and metribuzin suppressed the mycelial growth and the antagonistic potential of T. harzianum against F. oxysporium indicating the possibility of the integration between these pesticides and T. harzianum without any fear. However, the use of incompatible pesticides at all tested concentrations such as penconazole, iprodione, fenarimol and mancozeb and high concentrations of oxyfluorfen, glyphosate and imidacloprid may lead to inhibition of the growth and the antagonistic activity of T. harzianum as well as caution must be taken when using these pesticides in the disease management program. The obtained results will enable choice of combining T. harzianum with the selected pesticides within integrated disease management strategy.
VARIETAL RESPONSES TO STORAGE TREATMENT WITH NANOBIOTECHNOLOGY FOR REDUCTION OF POSTHARVEST LOSSES OF FRESH YAM ( DIOSCOREA SPP ) TUBER

Post-harvest food losses of yam constitute a huge source of food insecurity in Africa. A storage experiment was conducted in the Department of Crop Science, University of Nigeria, Nsukka to investigate the responses of three varieties of yam to application of silver nitrate and neem leaf extract (silvermeem) for reduction of postharvest losses of yam tubers in storage. It was a 3 x 4 x 3 factorial laid out in completely randomized design (CRD) experiment. The treatments comprised 3 varieties of yam; Dioscorea rotundata, Dioscorea alata and D. cayenensis with 4 levels of silverneem prepared as 0 mg/ml, 100 mg/ml, 200 mg/ml and 300 mg/ml solutions replicated three times. The apical sections of the yam tubers were soaked into 6 cm depth of each level of the prepared silverneem and allowed to stay for 3 min, air dried and placed on the wooden shelf in the barn. Temperature and relative humidity were monitored both inside and outside barn. Data were also collected on dormancy period, weight loss, rot incidence and sprout length. The improved yam barn reduced the temperature with (1.5 – 4.5 ± 1 0 C) and provided cooler environment for the yams compared to the outside barn temperature. The dormancy period of D. rotundata and D. alata were significantly (P ≤ 0.05) extended at the concentrations of 100 mg/ml and 200 mg/ml of the silverneem. Generally, the interaction effects of silverneem with variety significantly reduced dormancy period of D. cayenensis at 100 mg/ml but at 200 mg/ml the dormancy significantly increased. In the same vein, weight loss, rot incidence and sprout lengths were significantly reduced in D. alata, and D. cayenensis compared to D. rotundata. Linear correlation analysis result showed high positive and significant relationship between sprout length and tuber weight loss (r = 0.92). Interestingly, the green metallic nanoparticle of silverneem has no toxic chemicals and no adverse effect on food.

Proceedings of the 11 th ICEENG Conference , 3-5 April , 2018 13-CST

This paper considered a state of art as it employs a brand new technique to estimate the missing values in the dataset helping the classifiers to classify the data with better accuracy. also determining the effect of each attribute on the accuracy that enables researchers to get better or same accuracy with less number of attributes saving processing time, RAM, and memory needed. The aim of this paper is to improve accuracy of expecting Hepatitis mortality using worldwide dataset from Ljubljana University. We present an implementation of two brand new classification techniques. Using confusion matrix and K-fold cross validation technique to calculate classification accuracy. Two experiments have been done and the experimental results show that using the correlation in frequency domain after computing the weight factor for each attribute achieved better accuracy than using the subtraction method in time domain.
Quantum mechanics in terms of realism

We expound an alternative to the Copenhagen interpretation of the formalism of nonrelativistic quantum mechanics. The basic difference is that the new interpretation is formulated in the language of epistemological realism. It involves a change in some basic physical concepts. The ψ function is no longer interpreted as a probability amplitude of the observed behaviour of elementary particles but as an objective physical field representing the particles themselves. The particles are thus extended objects whose extension varies in time according to the variation of ψ. They are considered as fundamental regions of space with some kind of nonlocality. Special consideration is given to the Heisenberg relations, the Einstein-PodolskyRosen correlations, the reduction process, the problem of measurement, and the quantum-statistical distributions.
