A COMPARISON OF MULTIPLE TESTING METHODS: SPINOSAD AS A TREATMENT FOR LICE ON CATTLE

A common problem in statistics is making multiple tests of hypotheses without controlling for the type I error rate. SAS has identified several different methods to adjust p-values for multiple testing. To compare the effect of these methods, an animal health dataset that deals with the treatment of cattle lice was examined. Clinical trials were conducted in Illinois and Wisconsin to evaluate the efficacy of two formulations of a new product Spinosad, two commercially available positive controls, and an untreated negative control. A baseline lice count was recorded prior to the treatment. After treatment, weekly measurements of lice counts were taken for 8 weeks. Counts of 4 lice species were recorded separately. A linear mixed model analysis was conducted for each species of lice after transforming the counts with a natural logarithm transformation. Simple contrasts between treatment groups at each week were performed. Treatment differences were also compared using 5 multiple testing methods: Bonferroni, Sidak, Holm’s step-down Bonferroni, Hochberg's step-up Bonferroni, and false discovery rate. Seventy-one out of 96 simple tests showed significant differences among the treatment groups. The five multiple testing methods confirmed only 48-67 significances out of the 96 tests. Comparatively, Bonferroni and Sidak methods provided similar and the most conservative multiplicity test results, i.e. fewest significant differences. The Holm’s step-down and Hochberg's step-up Bonferroni methods provided similar but less conservative results. Finally, the false discovery rate method provided the least conservative results.
Fiscal Decentralization and Economic Growth in Nigeria: A Multivariate Co-Integration Approach

This paper examines the long run and causal relationship between fiscal decentralization and economic growth in Nigeria for the period 1970 to 2012 using time series data. Results from a multivariate VAR model provide evidence of long run relationship between fiscal decentralization and economic growth in Nigeria. The three measures of fiscal decentralization have a positive and significant relationship with economic growth, Granger Causality test reveals long run unidirectional link running from fiscal decentralization to economic growth. The study recommends the need for government to urgently address the constitutional issue of fiscal powers among the three tiers of government to further strengthen the fiscal base of the state and local governments and increase further the level of fiscal decentralization.
Air Emission Factors and Emission Rates in Asphalt Roofing Manufacturing

This study was focused on measuring air pollutants emission from factories producing the asphalt related products in Delijan Industrial Estate, which is the main center of asphalt related products in Iran. Emissions of four factories were analyzed for air pollutants using a stack analyzer, Testo 360, Testo Co., and Germany. The average concentration of all measured stacks for PM, THC, CO, NOx, SO2, and CO2 was 698.0, 195.4, 109.3, and 30.7, 15.1 mg/m 3 and 5.17%, respectively. Estimation of the emission rate for the studied factories with total annual production of 46,500 tons of shingles and rolling asphalt revealed the annual emissions of 32.9, 8.9, 5.0, 1.4, 1.1, and 4,423.4 tons/yr for PM, THC, CO, NOx, SO2, and CO2 respectively. It was also shown 435.4, 118.2, 66.7, 189.4, 14.1, and 58,503.1 tons/yr for those pollutants by all factories in Delijan Industrial Estate with annual production of 615,000 tons. The emission factors for the above-mentioned pollutants were 708.1, 192.2, 108.4, 30.8, 22.9, and 95,127 g/ton respectively. Comparing the results with national standard showed that, the PM emission concentration was 2 times greater than Iranian emission standard (250 mg/m 3 ) and its emission factor exceeded the USEPA emission factor. The rest of pollutants concentrations and emission factors were in the range of both standards. In conclusion, all studied factories need to reduce their particle emission using appropriate air cleaners.
Two-Dimensional Structures Composed of Cross-Shaped Molecules Adsorbed on Solid Surfaces – a Computational Model

Abstract The ability of simple molecular building blocks to form extended ordered patterns by adsorption and self-assembly on solid substrates is an advantageous property that has been widely used to create nanostructured surfaces. In this contribution we demonstrate how the lattice Monte Carlo simulation method can be used to predict morphology of adsorbed overlayers comprising simple functional cross-shaped molecules resembling phthalocyanines and porphyrins. In particular, we focus on the influence of the distribution of active interaction centers within a model crossshaped molecule on the structure of the resulting molecular networks. Additionally, we investigate how using racemic mixtures of input prochiral molecules affects the chirality and porosity of the corresponding ordered patters. The obtained results show that suitable manipulation of the chemistry of cross-shaped building block allows for the controlled creation of largely diversified molecular porous networks.
Deberes escolares y rendimiento académico en Educación Primaria

Resumen: En este articulo se analiza la relacion entre la realizacion de deberes escolares y el rendimiento academico en una muestra de estudiantes de los tres ultimos cursos de Educacion Primaria. Las variables vinculadas con la implicacion de los alumnos en los deberes escolares fueron el numero de deberes realizados, el tiempo dedicado a los deberes y el aprovechamiento del tiempo dedicado a los deberes; mientras que el rendimiento academico fue estimado en base a las notas en matematicas y lengua extranjera (ingles). Se ha tenido en cuenta el posible efecto del curso y del genero a la hora de calcular el nivel predictivo de las variables relativas a los deberes sobre el rendimiento academico. Los resultados obtenidos indican que la cantidad de deberes realizados de los prescritos y el aprovechamiento del tiempo predicen positiva y significativamente el rendimiento academico en ambas asignaturas, mientras que la cantidad de tiempo dedicado a la realizacion de los deberes no es relevante. Finalmente, mientras que el genero no resulto significativo en la prediccion del rendimiento academico, el curso si predijo negativamente el rendimiento en matematicas: a medida que se asciende de curso el rendimiento en matematicas tiende a disminuir. Palabras clave: Deberes escolares; implicacion en los deberes escolares; rendimiento academico; educacion primaria. Title: Homework and academic achievement in Primary Education.
Essays on Rural-Urban Migration and Firm Performance Differentials in China

This dissertation focuses on some important features of the Chinese economy, a key player in the global economy. Chapter 2 looks at the rural-urban migration with particular emphasis on the interaction between urban labor and housing markets. The long-held perception of the seemingly unlimited “cheap labor” has started to shift in the past decade with two puzzling observations: rapid growth in migrant wages and substantial migrant labor shortages despite the presence of a still large rural labor reserve. The theoretical and empirical work presented in this chapter is one of the first attempts to quantitatively examine the impact of the rising urban housing cost on migration, migrant labor shortages and migrant wages. Simulation results show that quantitatively the increase in the urban housing cost from 2004 to 2008 accounts for approximately 34 percent of the migrant wage increase observed in that time period and that the migrant labor supply is 11 percent less than it would have been had the housing price been fixed at the 2004 level. Chapter 3 investigates empirically how ownership type affects the performance, as measured by return on assets (ROA), of private (non-SOEs) versus state-owned enterprises (SOEs) before and after the state sector reform. The unconditional quantile regression results show that SOE ownership has a negative association with the ROA measure across the entire distribution in both preand post-reform periods. The effect is especially large at the upper and bottom quantiles. The decomposition iii analysis suggests that at the aggregate level, differences in the return to characteristics are relatively more important in “explaining” the ROA differentials at the bottom and upper quantiles in both preand post-reform periods, indicating that no matter whether before or after the reform the SOE ownership keeps firms in the upper quantiles from achieving top notch performance, and traps firms at the bottom quantiles from moving up the performance distribution. It is worth noting that although the SOE structure effect explains the majority of the ROA differential at the upper quantiles in both time periods, it becomes less of a problem after the reform.

THE EFFECT OF BLANCHING PRETREATMENT ON THE DRYING KINETICS, THERMAL DEGRADATION OF PHENOLIC COMPOUNDS AND HYDROXYMETHYL FURFURAL FORMATION IN POMEGRANATE ARILS

This study examined the effect of blanching pre-treatment on the drying kinetics, thermal degradation of phytonutrients and hydroxymethylfurfural (HMF) formation in pomegranate arils. Pre-treated and untreated arils were dried in a cabinet dryer operated at temperatures of 55, 65 and 75°C. The efficiency of the drying process was assessed according to the effective moisture diffusivity and activation energy values. Effective moisture diffusivities ranged from 0.59 × 10−9 to 5.62 × 10−9 m2 s−1 and activation energies for drying were 31.82 and 76.11 kJ/mol for pre-treated and untreated arils, respectively. Six thin-layer drying models were tested, and Page and Modified Page models were found to be the most suitable. The final quality of pomegranate arils was evaluated according to their total phenolic and total anthocyanin contents, their antioxidant capacities and the rate of HMF formation. The blanching pre-treatment prior to drying produced higher retention of antioxidant compounds with less HMF content and superior sensory properties. Sensory analysis results revealed that pre-treated arils were preferred to untreated arils.
Feasibility Study of Green Wastes Composting with Digested and Dewatering Sludge from Municipal Wastewater Treatment Plant in Iran

Background: Composting as a waste management technology is becoming more widespread. The purpose of this study was to assess the feasibility and to find the most effective composting process for the ratio of green waste, digested and dewatered sludge from Chonibieh wastewater treatment plant in the west region of Ahvaz.Methods: The composting time was 23 days and the evaluated parameters in this period of the study were organic carbon, total nitrogen, phosphorus, carbon to nitrogen ratio (C/N), moisture content and pH. The C/N ratio was maintained at 30 with weight:weight ratio of 1:1, 1:2, 1:3 (digested and dewatered sludge to green waste). Results: It was observed that vessel R3 produced higher quality of compost with final total nitrogen (1.28%), final total phosphorus (0.71%), final total organic carbon (TOC) (25.78%) and C/N (20.65%) within the 23 days of composting. While vessel R1 produced higher final total nitrogen and total phosphorus with lower amount of total coliform indicating suitable quality of composting. Therefore, the results showed that the characteristics of dewatered sludge mixed with green waste proportion of green waste significantly influenced the compost quality and process dynamics. The results also showed that the quality of final products in all the conditions was in agreement with Global Organic Textile Standard (GOTS) and World Health Organization (WHO) guidelines. However, the moisture content ratios were lower than the mentioned guidelines. With regards to microbial quality, all three ratios were in agreement with US Environmental Protection Agency (EPA) and Iranian guidelines.Conclusion: It is suggested that the final product of composting can be safely used in farmland and green space.
The Relation of Parental Emotion Regulation to Child Autism Spectrum Disorder Core Symptoms: The Moderating Role of Child Cardiac Vagal Activity

This study investigated the role of parental emotion regulation (ER) on children’s core symptoms in families of children with autism spectrum disorders (ASD) in middle childhood; the study also explored whether children’s physiological ER functioning served as a risk or protective factor with respect to parental relationships. Thirty-one Chinese children with ASD (age 6–11) and their primary caregivers participated in this study. Parental ER and child ASD symptoms were collected via questionnaires from parents. Child cardiac vagal activity (derived from heart rate variability) was measured at rest and during a parent-child interaction task. Using moderation analyses, the results showed that parental ER was not directly associated with children’s core ASD symptoms; rather, it interacted significantly with children’s resting cardiac vagal activity, but not task-related changes of cardiac vagal activity, to exert an impact on children’s core ASD symptoms. Specifically, our findings suggested that parents’ difficulties with their own ER significantly impacted their children’s core ASD symptoms only for the children who showed blunted resting cardiac vagal activity. Implications for the future measurement of ER in the family context and future directions for intervention are discussed.

Parameters affecting quality in manual assembly of engines

In manufacturing, it is vital that operators and other production personnel have the right information at the right time and right place. But what happens if we overestimate the usability of information for supporting the personnel in their assembly tasks? When does information serve as a quality assurance tool, and when does it become a too large part of the workload, thus reducing the time for core workplace activities, and instead becoming a part of the personnel’s workload? This paper reports on work that has been conducted at a heavy diesel engine assembly plant with the aim of finding information usability parameters that can affect the personnel negatively or positively. The paper presents and describes an evaluation of an existing information system at the plant. The aim of the evaluation was to find out why the assembly personnel, despite the fact that they had “all the information they needed”, did not always assemble the product according to specification and thereby caused an engine reject that had to be re-assembled. The initial hypothesis was that there would be a strong correlation between the production volume and the number of rejects due to “Information Overload”. However, the study revealed that the personnel do not use the IT system in a way that causes information overload. Instead, the degree to which the IT system supports/triggers different forms of information seeking behaviour is thought to be one of the main factors influencing internal reject.
The eJournal of the European Society of Minimally Invasive Neurological Therapy

INTRODUCTION: Telestroke systems as known today used currently recommend imply transfer of patients with acute strokes to Community Hospitals (CommH) that cannot offer endovascular procedures (EVT). The primary benefit of this policy relies on the fact that intravenous ( tissue plasminogen activator (ivtPA) one, may be offered earlier and two, unnecessary transfers to Comprehensive Stroke Centers (CSC) can be avoided. However, this strategy may generate time delays in potential EVT candidates. This study aimed to quantify the potential benefits and disadvantages of this strategy. METHODS: From March 2013 to March 2014, 533 teleconsults were centrally attended by stroke neurologists in the Catalan telestroke system that covers 105 CommH. We defined criteria to identify potential EVT candidates ion the f-field or in the CommH after teleconsultation (clinical and radiological). RESULTS: Eighty-four patients (15.7 %) could have been identified on-in the field before arrival to CommH as potential EVT candidates. Once at the CommH, of these 84 patients, 60 (71 %) were still potential EVT candidates after CT-scan and teleconsultation. Of these 84 patients, only 27 (32 %) received iv-TPA in the CommH; however 68 (80 %) were still emergently transferred to CSC, where only 13(19 %) finally received EVT. The median time from CommH-door to groin puncture was 216 min vVs CSC-door to groin 152 min for primary CSC admissions (p<0.01). CONCLUSIONS: Present telestroke systems offer safe and timely iv-tPA treatment to eligible patients but may induce a considerable time loss in EVT candidates. Only a third1/3 of the on-field potential EVT candidates benefit from admission in a CommH when being treated with iv-tPA, while more than three quarters 3/4 will still be transferred to the CSC.
Self-Enhancement of Scalar and Vector Holographic Gratings in Azobenzene Molecular Glassy Films

Self-enhancement (SE) effect of scalar and vector holographic gratings (HG) recorded in three different azobenzene molecular glassy films is experimentally studied in both transmission and reflection modes at 532 and 633 nm. The maximal SE factor (the ratio of diffraction efficiency to its initial value) SEF = 42 has been achieved. It is shown that the model of complementary HG can be applied also in scalar transmission thin HG case to explain coherent SE. The possibility of vector HG coherent SE in transmission mode is experimentally demonstrated for the first time (SEF = 4.3). The possibility of coherent HG SE in reflection mode is also established for the first time (SEF = 21). HG recording processes as well as coherent SE processes are found to be independent in transmission and reflection modes being determined by volume and surface relief HG, respectively. The permittivity gradient mechanism is proposed to explain the coherent SE of surface relief HG. Both HG recording and coherent SE efficiencies strongly decrease when HG period is decreased from 2 mm to 0.5 mm. No relaxational SE effect is found. Coherent SE effect in molecular glasses is found to be weaker than in inorganic materials.
Empirical comparison of sentiment analysis techniques for social media

Nowadays the excessive use of internet produces a huge amount of data due to the social networks such as Twitter, Facebook, Orkut and Tumbler. These are microblogging sites and are used to share the people opinions and suggestions on daily basis relevant to the certain topic. These are beneficial for decision making or extracting conclusions. Analysis of these feeds aims to assess the thinking and comments of people about some personality or topic. Sentiment analysis is a type of text classification and is performed by various techniques such as Machine Learning Techniques and shows that the text is negative, positive or neutral. In this work, we provide a comparison of most recent sentiment analysis techniques such as Naïve Bayes, Bagging, Random Forest, Decision Tree, Support Vector Machine and Maximum entropy. The purpose of the study is to provide an empirical analysis of existing classification techniques for social media for analyzing the good performance and better information retrieval. A comprehensive comparative framework is designed to compare these techniques. Various benchmark datasets (UCI, KEEL) available in different repositories are used for comparison purpose. We presented an empirical analysis of six classifiers. The analysis results that Support Vector Machine performs much better as compared to other. Efforts are made to provide a conclusion about different algorithms on the basis of numerical and graphical metrics to conclude that which algorithm is optimal.
Multiobjective structural damage identification in uncertain environments

Evolutionary algorithms are suitable to solve damage identification problems in a multiobjective context. However, the performance of these methods can deteriorate quickly with increasing noise intensities originating numerous uncertainties. In this paper, a statistic structural damage detection method formulated in a multiobjective context is proposed. The statistic analysis is implemented to take into account the uncertainties existing in the structural model and measured structural modal parameters. The presented method is verified by a number of simulated damage scenarios. The effects of noise and damage levels on damage detection are investigated.
