    Not many studies have so far quantitatively investigated the role of Multiple Intelligences (MI) in language teaching and almost no research has explored the role of MI in listening proficiency. In this study, the role of MI was investigated by giving one hundred and fifty-one junior and senior English language students an actual TOEFL listening comprehension test and a Multiple Intelligences Development Assessment Scales (MIDAS) questionnaire. The results suggest that, although all the intelligences positively correlate with performance on TOEFL listening comprehension, only linguistic intelligence has a statistically significant but low correlation with TOEFL listening. Furthermore, the results of regression analysis indicate that linguistic intelligence is included as a predictor of listening proficiency while other intelligences are excluded. The results provide quantitative data that, except for linguistic intelligence that has a small role, other intelligences do not make any contribution to performance in listening proficiency and learners with different intelligences have equal chances and only those with low linguistic intelligence need more help

    The fluidic thrust-vectoring modulation on a Bypass Dual-Throat Nozzle (BDTN) is studied numerically. The thrust vectoring modulation is obtained by varying the secondary mass flow, introducing different area contraction ratios of the bypass duct. The scope of present study is twofold: (i) to set up a model for the control of the secondary mass flow that is consistent with the resolution of the nozzle main flow and (ii) to derive a simplified representation of a valve system embedded in the bypass channel. The simulations of the turbulent airflow inside the BDTN and its efflux in the external ambient have been simulated by using RANS approach with RNG k-eps turbulence modeling. The numerical results have been validated with experimental and numerical data available in the open literature. The nozzle performance and thrust vector angle are computed for different values of the bypass area contraction ratio. The effects of different secondary mass flow rates on the system resultant thrust ratio and discharge coefficient of the bypass dual-throat nozzle have been investigated. By using the proposed approach to the secondary mass flow modulation, the thrust pitch angle has been controlled up to 27

    Abstract. Context and objectives: murder as a social phenomenon could be a potential danger for society and families, so studying its roots and causing factors would help to prevent the prevalence of this destructive phenomenon. Therefore, the present study was conducted to compare emotional character and Alexithymia in people committing first degree murder and ordinary people. Methods: the method used for this study was causal-comparative. The research population consists of all the prisoners in Yasuj prison committing murder in 2015 and 2016. 40 individuals committing murder were sampled directly and 40 ordinary people were matched and participated in the study. To collect data, emotional nature and Alexithymia questionnaires were used. The collected data were analyzed using multivariatevariance analysis tests. Findings: Multivariate variance analysis showed significant statistical difference between the scores of emotional nature and Alexithymia in both groups of people committing murder and ordinary people. Results: The results of the study show that people committing murder have a tendency towards novel and dangerous acts, and also have trouble expressing emotions and Alexithymia.Keywords: Emotional character, Alexithymia, Murde

    Experimental Study of Plasma Actuator Effects on Flow Field Separation Bubble around Blunt Flat Plate

    In this paper, the air flow around a blunt flat plate with a rounded leading edge has been experimentally examined with and without the presence of a plasma actuator. Tests have been conducted with Reynolds numbers ranging from 104 to 105. Significant phenomena in this flow field is the flow separation at the leading edge of the body, which called separation bubble. There are two considerably dimensionless parameters in this experiment. One of them is the leading edge radius ratio to body thickness and other one is the ratio of maximum velocity induced by plasma actuator to free stream velocity. Geometries with the values of R/D=0, 1/16, 2/16, 4/16 were tested. For each geometry, the effectiveness of plasma actuator on the separation bubble is studied in different values of velocity ratio. The results show that, the effect of plasma actuator for the geometry with sharp edge (R/D=0), is negligible, while in geometry with rounded edge, the plasma actuator has significant effect on the separation bubble domain. This effectiveness is enhanced, by increasing of leading edge radius and velocity ratio, so that in rounded edge geometry (R/D=4/16) length of separation bubble is reduced about 75%

    Subconjuntos de países por niveles de dependencia petrolera: propuesta para el análisis sociopolítico

    Get PDF
    The present work tries to make an exploratory analysis that allows to build analytical subsets within the general set of countries with oil dependence, useful for comparative sociopolitical studies. The methodological strategy was the typological analysis, which seeks to satisfy the need to classify by summarizing in a reduced and significant set of categories or types of units of analysis that come to be the object of study. The adjustment of the criteria established by the literature (Nankani, 1979; Ross, 2004; Haglund, 2011; Perry, Olivera, Ogunkola y Fowowe, 2012) was applied to general set of countries taking as key variables income as a percentage of GDP and fuel exports as a percentage of total exports. Thus, were established four subsets of countries by level of oil dependence that were tested with exploratory data analysis using diverse sociopolitical variablesEl presente trabajo tiene como objetivo hacer un análisis que permita construir subconjuntos analíticos dentro del conjunto de países con dependencia petrolera, útil para estudios sociopolíticos comparados. La estrategia metodológica es el análisis tipológico, que busca satisfacer la necesidad de clasificar, resumiendo unidades de análisis, en un conjunto reducido y significativo de categorías que vienen a ser el objeto de estudio. Se aplicó al conjunto de países un ajuste de los criterios establecidos por la literatura, tomando como variables clave renta (como porcentaje del PIB) y exportaciones de combustibles (como porcentaje de exportaciones totales). Así, se establecieron cuatro subconjuntos de países por nivel de dependencia petrolera que fueron probadas con análisis exploratorio utilizando variables sociopolíticas diversa

    Bad governance:How privatization increases corruption in the developing world

    Get PDF
    International organizations have become key actors in the fight against corruption. Among these organizations, the International Monetary Fund (IMF) maintains a powerful position over borrowing countries in its ability to mandate far‐ranging policy reforms – so‐called “conditionalities” – in exchange for access to financial assistance. While IMF pressure can force the implementation of anti‐corruption policies, potentially reducing corruption, other IMF policy measures, such as the privatization of state‐owned enterprises, can create rent‐extraction opportunities and limit the capacity of state institutions to limit corrupt behavior. To test these mechanisms, we conduct instrumental‐variable regression analysis using an original dataset on IMF conditionality for up to 141 developing countries from 1982 to 2014. We find that conditions to privatize state‐owned enterprises exert significant detrimental effects on corruption control. Conversely, other areas of IMF intervention are not consistently related to corruption abatement. These findings offer policy lessons regarding the design of conditionality, which should avoid large‐scale privatization, especially under conditions of weak accountability

    New Petro‐aggression in the Middle East: Saudi Arabia in the Spotlight

    Get PDF
    That hydrocarbon abundance may lead to more violence is an established truism in the literature on the resource curse. Looking at the Middle East, however, the literature relates bellicose state behaviour entirely to oil-producing revolutionary republics. Instead, dynastic monarchies are claimed to be the more peacefully behaving actors. Current developments turn this conclusion upside down, however. Since 2015 at the latest, the foreign policy of Saudi Arabia, the leading monarchy in the Middle East, has transformed from multi-dependence to petro-aggression. By discussing this striking transformation, the paper puts forward a framework looking at the interaction of three crucial dimensions: first, the decreasing power projection towards the Middle East by the United States, the decade-long hegemon, due to gradual changes in world energy markets and war fatigue at home; second, the lasting fiscal potency of the Saudi regime; and, third, the personalization of the Saudi monarchy under King Salman as a historically contingent result of transferring power to the generation of Ibn Saud's grandsons

    Rentier Statebuilding in a Post-Conflict Economy: The Case of Kosovo

    Get PDF
    Kosovo has been under various forms of international administration since 1999. Although the political dimension of this international experience has been widely studied by scholars — especially those associated with the critical theory of liberal peacebuilding — the economic dimension of international rule has received less attention. This article explores the economic dimension by linking insights from rentier theory with critical approaches to liberal peacebuilding and statebuilding. The postulate informing this article is that the sources of a state's income have an impact on its institutional development. The article discusses liberal peacebuilding through the lens of rentier theory, it analyses the economic management in the early years of the international administration of Kosovo, and describes and explores some of the unintended consequences of this massive international presence in Kosovo for the local economy
