The Scale Of Being Able to Say “No” For Children: Validity And Reliability Analysis
Authors: Yılmaz Ferat , Sözer M. Akif
Published: March 2018

In this study, it is aimed to develop a scale
for assessing children’s ability to say “no”. The participants included in the study
are the area experts that helped to achieve content validity, and fourth
graders who are asked to score the items in the SN to have an idea about the
construct validity, measurement reliability and item discrimination of the item
in the scale. In this study, four different drafts of the SN which contained 24
items of 3-pointed Likert type, 22 items of 3-pointed Likert type, 12 items of
3-pointed Likert type and 12 items of 5-pointed Likert type were used. In order
to evaluate the content validity of the SN, the experts’ opinions were
received. For the construct validity, exploratory and confirmatory factor
analyses were conducted. Reliability of measurements obtained with the SN was
analyzed by using the methods of Cronbach’s Alpha and Split-half. An opinion
was formed about the distinctiveness of items in the scale setting out from the
corrected item total correlations (CITC) and the results of the independent
samples t-tests. The results of the study showed that the SN can be used as a
data collection tool, and is able to produce valid and reliable interpretations
in studies that aim to explore children’s ability to say “no”.
Political Science in Canada on Post-Independence Ukraine
Authors: Jaworsky Ivan (John)
Published: March 2018

When Ukraine became an independent state, Canada’s political science community, and the country’s Ukrainian studies infrastructure, generally lacked the expertise to effectively analyze the ensuing political changes in Ukraine. Over the years that followed there has been a growing awareness of the importance of studying politics in Ukraine, and a realization that greater efforts should be made to infuse the traditional area studies approach, which dominated studies of Ukraine in the past, with greater methodological rigour, and to situate political developments in Ukraine within a broad comparative context. As a result, Canadian academics are now in a much stronger position to contribute to the study of politics in Ukraine. There is, however, much room for improvement.

Development and validation of modified QuEChERS method coupled with GC-MS/MS for 123 pesticide residues in food
Authors: KIVRAK Şeyda , HARMANDAR Mansur
Published: March 2018

In
this study, a gas chromatography-tandem mass spectrometry (GC-MS/MS)
instrument, which has been widely used in recent years and has high separation
power, selectivity and ability to identify pesticides has been used. It is
aimed that the main criterion of this analytical method, in which the QuEChERS
methodology is used, is applicable to fast, easy, cheap, environmentally
friendly and different matrices. At the same time with this method, 123
pesticide residues and their degradation products were quantitatively assayed
by GC-MS/MS as well as method validations in tomatoe, lemon, lettuce, almonds,
raisins, honey, green pepper, milk and flour. Tomatoe was selected as potential
reference matrixes for the target. The steps of concentration and solvent
exchange were performed in the resultant extracts for the purpose of improving
analytical performance in terms of recovery, precision, linearity, of reducing
the amount of co-extracts. Multiple reaction monitoring (MRM) was used to
identify and quantify the pesticides. The samples were extracted with 1% acetic
acid in acetonitrile, anhydrous magnesium acetate, anhydrous magnesium sulfate
and clearing agent. For all pesticides, good linear calibrations with
coefficients (R2) ≥0.99 for nearly all of the analytes were obtained.  Limit of quantitation of most of the
pesticides were in the range of 5-10 ng/g, and recovery of the method
validation accuracy parameter was done at two different concentrations 10 ng/g
and 50 ng/g were 88.6 - 99.7% and CV 1.60 – 14.0%.
Fair split of profit generated by n parties
Authors: Mualem Elinor , Zaks Abraham
Published: March 2018

The authors studied the process of merging insured groups, and the splitting of the profit that arises in the process due to the fact that the risk for the merged group is essentially reduced. There emerges a profit and there are various ways of splitting this profit between the combined groups. Techniques from game theory, in particular cooperative game theory turn out to be useful in splitting of the profit. The authors proceed in this paper to apply techniques of utility theory to study the possibility of a fair split of that profit. In this research, the authors consider a group of n parties 1,...,n such that each of them has a corresponding utility function u1(x),...,un(x) . Given a positive amount of money C, a fair split of C is a vector (c1,...,cn) in Rn, such that c1 +...cn = C and u1(c1) = u2(c2) = ... = un(cn). The authors presume the utility functions to be normalized, that is ui(c) = 1 for each party i, i = 1, ... ,n. The authors show that a fair split exists and is unique for any given set of utility functions u1(x), ..., un(x), and for any given amount of money C. The existence theorem follows from observing simplexes. The uniqueness follows from the utility functions being strictly increasing. An example is given of normalizing some utility functions, and evaluating the fair split in special cases. In this article, the authors study the case of merging two groups (or more) of insured members, they provide an evaluation of the emerging benefit in the process, and the splitting of the benefit between the groups.

Authors: Mostafa Harby , Sultan Wael
Published: March 2018

Drip irrigation systems have become a major part of developing agriculture in Egypt and the aim of this research was to obtain the best performance from irrigation systems management using locally modified and original emitters. The experiments were carried out at the National Irrigation Laboratory of the Agricultural Engineering Research Institute. The emitters were tested and calibrated under different operating pressures (0.50, 0.75, 1 and 1.25 bar) to determine emitter flow rates and emitter emission uniformity (EU) and manufacturing variation coefficient (CV). The original emitter performance was determined using the relationship between emitter flow rate (2 lh−1) and operating pressure, with data indicating that the EU was 98.5%, at a CV of 2.3% and actual flow rate was 1.8 lh−1 for the original emitter. The EU was 93.8% with a CV of 5.2% and actual flow rate of 2.02 lh−1 for the modified emitter. For original emitter performance at 4 lh−1, data indicated that the EU was 96%, with a CV of 4.8% and actual flow rate of 3.78 lh−1. The EU for the modified emitter was 95% with a CV of 2.7% and actual flow rate of 4.5 lh−1. The emitter exponent values were 0.41 to 0.44 for modified and 0.37 to 0.38 for original emitters.

The non-aligned humanism of Rudolf Bruci: The composer and the society of self-management socialism
Authors: Sovtic Nemanja
Published: March 2018

In 1979 the oratorio We Are All a Single Party was performed, composed by the
Yugoslav composer Rudolf Bruci, who in an interview for the Novi Sad daily
newspaper Dnevnik explained his driving motives in the following way: ?I
wanted to preserve the spirit of our revolutionary songs and to speak in a
modern, familiar way, understandable to everyone, about the decades in which
our revolution was born and grew; about the legendary activities of pre-war
communists, the difficult days of the War of National Liberation, the
liberation and reconstruction of the country, about Tito and his invaluable
contribution to the development of our selfmanagement socialism and
non-aligned humanism? (Dnevnik, 10 April, 1979). In this article I argue
that the syntagm ?non-aligned humanism? is suitable for identifying the
connection between the aesthetic and the political in Rudolf Bruci?s
creative output, observed as a consistent author?s opus. At the core of this
thesis lies the assumption that non-alignment in regard to the West or East
was a major political and aesthetic orientation of Yugoslav self-management
socialism. The intersubjective field of this self-management socialist
pluralism produced creative entities - composers such as Bruci - whose works
were created under the principles of direct political engagement and
modernist aestheticism as different manifestations of the same ideology.
Within the specific rationality of non-aligned humanism, the concrete
poetic-morphological characteristics of Bruci?s compositions become coherent
subjective (Bruci?s personal) and objective (social) achievements.
Reflections on a ‘shop’ melodic model in wedding and St George’s day songs from eastern and Central Serbia
Authors: Jovanovic Jelena
Published: March 2018

This article examines a melodic model that characterizes Serbian ?Shop?
musical idiom both in eastern and central Serbia, where it was disseminated
through migrations from the ?Shop? cultural region to the west and northwest.
In some of the ?Shop? areas and in neighbouring regions in East Serbia, as
well as in more remote central Serbia, examples of this model are consistent
in their main characteristics, while in more remote areas in central Serbia
these characteristics appear in various forms of the model. The goal of this
paper is to contribute to knowledge of the distribution of elements of ?Shop?
musical culture in eastern and central Serbian areas.
Effect of Mold Type and Diameter on the Depth of Cure of Three Resin-Based Composites
Authors: AlShaafi MM , AlQussier A , AlQahtani MQ , Price RB
Published: March 2018

Objective:

To evaluate the effects of different mold materials, their diameters, and light-curing units on the mechanical properties of three resin-based composites (RBC).

Methods and Materials:

A conventional nano-filled resin composite (Filtek Supreme Ultra, 3M Oral Care, St Paul, MN, USA) and two bulk-fill composites materials, Tetric Evoceram Bulk fill (Ivoclar Vivadent, Schaan, Liechtenstein) and Aura Bulk Fill (SDI, Bayswater, VIC, Australia), were tested. A total of 240 specimens were fabricated using metal or white semitransparent Delrin molds that were 4 or 10 mm in diameter. The RBCs were light cured for 40 seconds on the high-power setting of either a monowave (DeepCure-S, 3M Oral Care) or polywave (Bluephase G2, Ivoclar Vivadent) light-emitting diode (LED) curing unit. The depth of cure was determined using a scraping test, according to the 2009 ISO 4049 test method. Data were analyzed using multivariate analysis of variance followed by Tukey multiple comparison test (p<0.05).

Results:

In general, when used for 40 seconds, both LED curing lights achieved the same depth of cure (p=0.157). However, the mold material and its diameter had a significant effect on the depth of cure of all three RBCs (p<0.0001).

Conclusion:

Curing with either the polywave or monowave LED curing light resulted in the same depth of cure in the composites. The greatest depth of cure was always achieved using the 10-mm-diameter Delrin mold. Of the three RBCs tested, both Tetric Bulk Fill and Aura achieved a 4-mm depth of cure when tested in the 10-mm-diameter metal mold. Tetric Bulk Fill was the most transparent and had the greatest depth of cure, and the conventional composite had the least depth of cure. Very little violet (<420 nm) light penetrated through 6 mm of any of the RBCs.

Listin að mennta sumarskáld: Um kenningar Dr. Brodda Jóhannessonar
Authors: Þórlindsson Þórólfur
Published: March 2018

Dr. Broddi Jóhannesson var einn áhrifamesti skólamaður tuttugustu aldar á Íslandi. Hann lét til sín taka á nánast öllum sviðum menntunar- og skólastarfs. Broddi var sjálfstæður hugsuður. Hann fléttaði saman vísindarannsóknir, íslenska bændamenningu, eigin athuganir og reynslu á afar frumlegan og sérstæðan hátt. Reyndar setti hann aldrei fram grundvallarkenningar sínar í samræmdri heild. Hann bauð ekki heldur upp á formúlur eða staðlaðar skyndilausnir í kennslu og skólastarfi. Þess í stað lagði hann áherslu á frelsi nemenda og kennara til þess að velja sér verkefni, ákveða kennsluaðferðir og efnistök, takast á við óvissu og efla kjark efans. Þannig vildi Broddi ná því markmiði skólastarfs að veita öllum nemendum jafnt sem kennurum tækifæri til þess að verða sjálfstæðir, skapandi einstaklingar, tilbúnir til þess að takast á við viðfangsefni daglegs lífs og sækja fram á eigin forsendum. Í þessari grein er fjallað um nokkrar grunnhugmyndir Brodda um uppeldi og skólastarf. Þá er leitast við að sýna fram á hvernig Broddi vann með þaulhugsað greiningarkerfi er setti manngildið ofar skrifræði, frelsi og sköpun ofar stöðluðum vinnubrögðum og gagnrýnin vinnubrögð ofar kennivaldi og kreddutrú.

Nemendum af erlendum uppruna hefur fjölgað mikið í íslenskum skólum. Það kallar á að skólar bregðist við námsþörfum þessa nemendahóps. Markmið þessarar greinar er að fjalla um reynslu kennara og foreldra af menntun nemenda af erlendum uppruna. Í eigindlegri rannsókn voru tekin viðtöl við þrjátíu og átta grunnskólakennara um reynslu þeirra af því að kenna nemendum af erlendum uppruna og helstu áskoranir sem því fylgja. Einnig voru tekin viðtöl við tíu erlenda foreldra um reynslu þeirra af íslenskum skólum. Niðurstöður sýna að kennarar telja sig ekki vera nægilega vel studda til þess að skilja og takast á við námsþarfir nemendanna. Upplifun foreldra litast af hugmyndum þeirra um skólann sem hinn hefðbundna stað fyrir nám og íslenska skólakerfið ögrar þessum skilningi þeirra. Skortur er á samvinnu og samskiptum milli forelda og kennara. Í niðurlagi er lagt til að skólar stuðli að markvissari umræðu um þarfir nemenda og væntingar foreldra svo að efla megi og bæta menntun nemenda af erlendum uppruna.
Characteristics and outcome for heart failure patients with mid-range ejection fraction
Authors: Wang Nelson , Hales Susan , Barin Edward , Tofler Geoffrey
Published: March 2018

Aims

The aim of this study was to compare precipitants, presenting symptoms and outcomes of patients with heart failure and mid-range ejection fraction (HFmrEF), heart failure and preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) in an Australian cohort.

Methods

We divided 5236 patients in the Management of Cardiac Failure program in Northern Sydney Australia, into HFmrEF (n = 780, 14.9%), HFpEF (n = 1956, 37.4%) and HFrEF (n = 2500, 47.8%), using a cutoff left ventricular ejection fraction of 40–49, at least 50 and less than 40%, respectively.

Results

For most characteristics, the HFmrEF patients were intermediate. Hypertension among the HFrEF, HFmrEF and HFpEF groups was present in 50.6, 61.7 and 68.9%, respectively; age more than 85 years was present in 35.1, 37.6 and 42.2%; atrial fibrillation in 35.3, 44.2 and 49.9%; and elevated serum creatinine (>100 μmol/l) in 59.2, 55.6 and 51.0%. For ischemic heart disease and ischemia as a precipitant of admission, HFmrEF patients were similar to the HFrEF group, and more common than in HFpEF. Mortality rates were not significantly different between the three groups. Readmission rates were highest for HFpEF (40.2%), followed by HFmrEF (42.4%) and HFrEF (45.4%), largely due to differences in nonheart failure readmission.

Conclusion

Clinically, HFmrEF represents an intermediate phenotype, with the exception of resembling HFrEF with a higher incidence of ischemic heart disease.
Macroeconomic Dynamics and the Manufacturing Output in Nigeria
Authors: Onakoya Adegbemi Babatunde
Published: March 2018

This paper examined the impact of the changes in the macroeconomic factors on the output of the manufacturing sector in Nigeria from 1981 to 2015. Preliminary evaluation of the data was conducted using both descriptive statistics and stationarity evaluation. The test indicated that not all the variables are normal. The occurrence of order integration at first level difference necessitated the deployment of the Johansen cointegration test. The findings revealed no short run association among manufacturing output and each of GDP, exchange rate, broad money supply and unemployment rate. Negative relationship existed amongst inflation rate, interest rate, exchange rate, broad money supply on one hand, and manufacturing output. The inflation rate and interest rate, were statistically insignificant. However, significant and positive relationship existed between GDP of the previous year and unemployment on the one hand and manufacturing output on the other, at 5 percent level. The results showed that manufacturing was a veritable engine of economic growth. The post estimation tests showed presence of serial correlation but evidence of heteroscedasticity existed which, made the model inefficient, but its estimator is still unbiased. The study recommended the harmonization of both fiscal and monetary policies for the attainment of macroeconomic stability and avoidance of rapid policy summersaults.

Published: March 2018

This paper discusses the issue of the specificities of the relationship of the comparative and the historical methods in the research of political history. We find examples of the relationship of the comparative and the historical methods in the research of political history in works of modern historiography. Contemporary political history studies various forms of political reality, a variety of themes and those subject to fad, like other branches of history. The analysis has shown that all general scientific methods, particularly the historical method, as well as the comparative method, enable the scientific cognition of social, historical and political phenomena and processes, which also applies to the research of political history.
Global Volatility Spillover, Transaction Cost and CNY Exchange Rate Parities
Authors: Ishfaq Muhammad , Qiong Zhang Bi , Abbas Ghulam
Published: March 2018

The present study examines the intertemporal association between CBOE market volatility indices (VIX), foreign exchange rates and respective bid-ask spread for four CNY exchange rate parities. For this purpose, the study utilizes the stylized EGARCH (1, 1) model for the period of 2011 to 2016. Results report that negative slopes of EUVIX, BPVIX, and JYVIX imply a higher level of volatility, hence improves the underlying exchange rate through appreciation, while positive slopes of VXFXI deteriorates exchange rates during the sample period. Similarly, high volatility widens bid-ask spread which, in turn, deteriorates respective exchange rate and vice versa. The market-oriented policies of China increased the forecasting capability of options volatility indexes to anticipate exchange rate dynamics from 2% to 5%. This indicates that flexible exchange rate regimes lead to increase the predicting power of micro structural components. Assessments of Post-reforms in CNY exchange rate evidence the rise in volatility in financial markets of China, which may discourage investor confidence and seeks for ‘flight to safety’ effect. While, low volatility reduces bid-ask spread which improves underlying exchange rate. The level and variance estimates of exchange rates and spreads reveal that there exists a significant relationship with VIX indices which implies that GARCH forecasts outperform in anticipating future volatility. The volatility estimates of variances show the persistence of volatility and absence of leverage effect. Overall, this article suggests that VIX index can act as ‘fear gauge’ indicator and its potential direction may guide investors in anticipating the movements of CNY exchange rate parities. Moreover, outcomes provide imperative implications to monetary and financial institutions for policy framing.

Published: March 2018

The aim of this research is to know the relationship between lemuru fish catch to Sea Surface Temperature (SST), El-Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) phenomenon in Bali Strait. The results showed, that in the period 2007 – 2016. fluctuations of catches lemuru tends to decline. Sea Surface Temperature (SST) distribution with the lowest temperature 25,28oC at 24,53oC - 27,16oC and the highest temperature is 29,31oC in the range of 28,730C – 30,490C. The lowest temperature occurred in July - September while the highest temperature occurred in January - April. Based on the calculation there is a linkage and relationship between catch and SST as shown on the value of determination and correlation reached 50,0% and 70,73%. Most of the catches occurred in the west season and then the transition II, transition I and East Season. The relationship of ENSO phenomenon to the catch during the El-Nino phase of lemuru catch will increase while in the phase of La-Nina the catch of lemuru will decrease, because time of El-Nino phase of the sea surface temperature (SST) relative low which results in the chlorophyll-a mean case which is a food sources of lemuru fish. Based on Trenberth's theory, (1997), the rise and fall of the ENSO Index of less than six months is not stated in ENSO. From the calculation results during the research of 2007 - 2016 happened three times ENSO phenomenon that is in 2009, 2010 and 2015. At the time of the IOD phenomenon, the IOD (+) phase will result in a decrease in catch while the normal IOD phase and (-) will increase the catch. From the results of this study can also be observed, in the year 2007 - 2011 phenomenon ENSO and IOD have a strong influence on the catch while in the year 2012 - 2016 the influence of the phenomenon of ENSO and IOD has no strong influence caused by the quantity of lemuru fish that have been over exploitation that resulted in the current Bali Strait on Over Fishing status.

Authors: Slaheddine Bessadok Abdelhak Rhouma, Naoufel Hamouda,
Published: March 2018

Very few studies of the potential of Hydrogen (pH) of water and sediment wetland at Ramsar site 2076/2012 have been reported in the literature. In this context, a sampling was collected from five sites of Oued El Malah and Tarf El Maa (north of Gabes: south-east of Tunisia). The results showed that the pH complies with national and international regulations (6.5 ?pH ? 8.5). Indeed, the hydrogen potential of water was varied between 7.88 (S2) and 8.24 (S1). It is ranged from 7.76 (S1 and S2) to 8.05 (S4) for sediments. Positive correlation (r = 0.985) and highly significant difference (P <0.01) were recorded for water and sediment pH. To confirm or refute this hypothesis, additional studies (physicochemical, biochemical and bacteriological analysis) are needed to assess the quality of these areas.

Published: March 2018

The present study was carried out to study the genetic parameters for yield, yield contributing, quality and nutritional characters along with reaction of genotypes against iron chlorosis in vertisols. The experiment consisted of 50 promising genotypes along with standard checks viz., Basmati-370, Parag and Avishkar were grown in randomized block design with three replications. The analysis of variance revealed that all the characters under study. Different genotypes showed some degrees of tolerance to iron chlorosis. And, some other characteristics like number of effective tillers per plant, number of filled grains per panicle, number of unfilled grains per panicle, gel consistency, flag leaf area, straw yield, grain yield per plot and grain yield per plant showed high estimates of phenotypic coefficient of variation, high heritability with high genetic advance. All characters which exhibited high estimates of both genotypic and phenotypic variance coupled with high heritability and high genetic advance can be employed for simple selection for crop improvement. Furthermore, variation in such characters are result of additive gene effects and can be explored and studied for potentialities of being used as parents in breeding program for improvement for particular traits.

O uso de antibióticos como aditivo melhorador de desempenho tem sido proibido pela possibilidade de favorecer o desenvolvimento de resistência bacteriana em humanos. Com isso, o objetivo da realização do trabalho foi avaliar o efeito da suplementação do prebiótico mananoligossacarídeo na alimentação de codornas japonesas e europeias em crescimento. Foram usadas 240 codornas de cada linhagem (Coturnix japonica e Coturnix coturnix) distribuídas em delineamento experimental inteiramente casualizado e arranjados em fatorial 2 x 4 (genótipos x níveis de suplementação de prebiótico) e seis repetições de dez aves. As codornas foram alimentadas com ração basal suplementadas com 0,0; 0,05; 0,10 e 0,15% de mananoligossacarídeo em substituição ao inerte. Não houve efeito de interação para nenhuma das variáveis avaliadas (P>0,05). Os níveis de suplementação do prebiótico não afetaram o desempenho e as características de carcaça (P>0,05) das codornas. O consumo de ração não foi alterado entre os genótipos (P>0,05), por outro lado, as codornas europeias apresentaram maior ganho de peso e melhor valor de conversão alimentar (P≤0,05) que as codornas japonesas. Os genótipos comerciais de codornas diferiram nas características de carcaça (P≤0,05). Recomenda-se formular rações sem suplementação do prebiótico mananoligossacarídeo para codornas japonesas e europeias de 21 a 42 dias de idade em ambiente considerando limpo.

O 2,4-D (ácido diclorofenoxiacético) é amplamente utilizado no controle seletivo, pós-emergência, de plantas de folha estreita, como trigo, milho, arroz, entre outras. Contudo seu uso indiscriminado pode ocasionar problemas no desenvolvimento da cultura. O objetivo do trabalho foi avaliar os danos causados pelo uso inadequado do 2,4-D no desenvolvimento inicial da soja (Glycine max). Os tratamentos consistiram na combinação de cinco períodos de carência: um, quatro, oito, 12 e 15 dias antes da semeadura da soja e duas doses de aplicação: a dose recomendada e a dose duplicada (L/ha), consistindo em um esquema fatorial 5x2 com três repetições. As plantas foram cultivadas por 44 dias, e em seguida coletadas e analisadas quanto à taxa de germinação (%), número de rebrota, índice de clorofila, comprimento de raiz e parte aérea (cm), massa seca e fresca (g). A dose duplicada revelou maior efeito sobre todas as variáveis analisadas, reduzindo em 20% a porcentagem de emergência. O índice de clorofila decresceu quando comparados o menor período de carência (um dia) e o maior (15 dias), e na dose duplicada. A massa seca também foi superior na dose recomendada, assim como o comprimento da raiz e da parte aérea. Os períodos de carência de um, quatro e oito dias foram os que mais influenciaram o crescimento da raiz.

Published: March 2018

Lapping is a crucial surface super finishing technology which includes rubbing of flat surfaces by introduction of abrasive slurry between them performed either by hand reciprocating movement or assisted by machine. Graphite, being commonly used material as base for precision measuring instruments is selected for experimentation and hence required high level of accuracy. By making slight modifications in the conventional lapping process, enhanced level of resulting surface finish can be achieved. In the current experiment, static pressure plate is replaced by vibratory mechanism. Analysis of variance has been carried out to identify the most influencing input parameter on the response parameters by performing series of experiments.
