The Role of Religious Orientation, Psychological Well-Being, and Self-Esteem in Iranian EFL Learners’ Language Achievement

The present study aimed at finding the relationship of religious orientation (RO), psychological well-being (PWB), and self-esteem (SE) with language achievement (LA) among Iranian EFL learners. Furthermore, it investigated the predictability of dependent variable (LA) using all independent and predictor variables (RO, PWB, and SE). 126 senior and junior students majoring in English Translation and English Literature at Shahid Bahonar University of Kerman participated in the study. To obtain the required data, three questionnaires were utilized: Allport and Ross’s (1967) Intrinsic-Extrinsic Religious Orientation Scale (IEROS) to measure extrinsic and intrinsic religious orientations, Short Measurement of Psychological Well-Being by Clarke, Marshall, Ryff, and Wheaton (2001) to measure psychological well-being, and finally, The Rosenberg Self-Esteem Scale by Rosenberg (1965) to assess self-esteem. Moreover, participants’ GPAs in major courses were used as indicators of their language achievement. For analysis of data, Pearson Product Moment Correlation and Regression analysis were used. The results revealed that there was a significant positive relationship between IRO, PWB, and SE with LA and a significant negative relationship between ERO and LA. Additionally, all the independent variables together could predict LA and accounted for 95 percent of variability of students’ GPA.
Intersectionality of acculturation and friendships in Asian youths: A review of the literature

In 2010, approximately 17.3 million people in the United States identified as being full or part Asian, representing the fastest growing race group in the United States from 2000 to 2010. The growing number of Asians living in the United States elicits questions about the daily experiences of these individuals as they navigate the journey of acculturating to a new life in a new country. Thus, acculturation—the process of cultural change resulting from adapting and adjusting to a new culture—earns a spotlight in the literature of cross-cultural psychology. However, much of the acculturation literature lacks depth and breadth of information regarding how acculturation and acculturative stress can impact not just the psychological, but also the social adjustment for many Asian youths. In Westernized societies, adolescence is viewed as a time marked by increasingly important peer relationships. Drawing from the significance of acculturation and social relationships for Asian youths, this paper examines how the nature of peer relationships plays against the backdrop of acculturation. Specifically, it examines the extant literature on acculturation and peer relationships in Asian youths in order to promote meaningful dialogue about the intersectionality between the two domains. Further, gaps in the current landscape of acculturation research are addressed, and future directions to propel research in cross-cultural psychology are proposed.
Post Stall Behavior of a Lifting Line Algorithm

A modified lifting line algorithm is considered as a low-cost approach for calculating lift characteristics of wings above stall. The model employs a numerical lifting-line method utilizing the 3D vortex lifting law along with known 2D airfoil data to predict the lift distribution across a wing. This method is expected to be of significant importance in the design of tailsitter vertical take-off and landing (VTOL) aircraft where the aircraft experiences stall conditions during important flight maneuvers. The algorithm is presented, and results compared with published experimental data.
Seasonal Changes on Termite Foraging Behaviour under Different Habitats in Rufiji District Tanzania

The effect of wet and dry season on termites foraging was examined in cropland, forest and grassland in Rufiji district for a period of one year. Termites species richness as well as abundance were sampled using standardized transect lines. Sampling was carried out on monthly basis. Termite species abundance was significantly different between the three locations, but species richness was not significantly different. These results reveal that termite abundance was higher in disturbed habitat due to the removal of vegetation which denies termites food and areas for nesting. Furthermore movement of termites from lower horizons during the wet season was higher than in the dry season. Key words: Termites activity, abundance, species richness, Rufiji district.
An Alternative System GMM Estimation in Dynamic Panel Models

The system GMM estimator in dynamic panel data models which combines two moment conditions, i.e., for the differenced equation and for the model in levels, is known to be more efficient than the first-difference GMM estimator. However, an initial optimal weight matrix is not known for the system estimation procedure. Therefore, we suggest the use of 'a suboptimal weight matrix' which may reduce the finite sample bias whilst increasing its efficiency. Using the Kantorovich inequality, we find that the potential efficiency gain becomes large when the variance of individual effects increases compared to the variance of the idiosyncratic errors. (Our Monte Carlo experiments show that the small sample properties of the suboptimal system estimator are shown to be much more reliable than any other conventional system GMM estimator in terms of bias and efficiency.

Shareholder Lockup Agreements in the European New Markets

We analyse the characteristics of lockup agreements of IPOs on the Neuer Markt and the Nouveau Marche from 1996 to 2000.Even though both markets were part of the same EuroNM network, the characteristics of their lockup agreements are substantially different.Firm characteristics have a major influence on lockup contracts.In addition, shareholder characteristics explain the diversity of contracts within the same firm.Although the French regulator offers two types of minimum lockup contracts, the market perceives a difference between the two contracts as the choice is influenced by the type of the firm and the type of shareholders.
Differential allelopathic activity of Parthenium hysterophorus L. against canary grass and wild oat.

Allelopathic effects of invasive weed parthenium (Parthenium hysterophorusL.) were studied by using whole plant, leaf and root aqueous extracts at 0, 2.5, 5.0, 7.5 and 10% (w/v) concentrations against germination and early seedling growth of wild oat (Avena fatua L.) and canary grass (Phalaris minor Retz.). Studies were carried out in Petri plates using filter paper as substratum placed in controlled conditions and soil -filled plastic pots placed in open environments. Both the experiments were laid out in a completely randomized design using four replicates. Pronounced variation was noticed for allelopathic activity of different plant parts of parthenium, extract concent rations, test species, and bioassay techniques. Parthenium extracts either inhibited or delayed the germination and suppressed seedling growth of test species. Various germination and seedling growth attributes were diminished to a much greater extent in P etri plates than in soil. Soil application of these extracts failed to reproduce results identical to those achieved in Petri plates , suggesting variable allelopathic response under different bioassay techniques. Leaf extracts were more suppressive to germination of test species than whole plant and root extracts in both Petri plates and pot studies at all concentrations. Highest chlorophyll inhibition coupled with enhanced tissue phenolic contents w as recorded by aqueous extracts of parthenium in both the test species. Canary grass appeared to be more susceptible than wild oat at all concentrations of aqueous extracts. It is concluded that bioassays conducted under controlled condition using filter paper as substratum may be misleading due to over estimation of allelopathic response and variation in potential of receiver and donor species . Hence, allelopathic bioassays must consider the components of natural settings in order to generate ecologically rel iable information.
Controlling DNA translocation speed through graphene nanopore via plasmonic fields

We propose a novel plasmonic-based method for controlling translocation speed of DNA molecule through graphene nanopore. Dynamic properties of a double-stranded DNA molecule passage through a graphene nanopore are investigated by employing molecular dynamics simulation. Also, the effect of plasmonic fields parallel to the graphene plane on the translocation speed of the DNA molecule is studied. The DNA translocation speed is calculated for different values of confinement, spectral width, and power of the plasmonic field. Results show the potential of the method for controlling translocation speed of DNA via surface plasmons in graphene nanopore. The plasmon field power, confinement depth, and spectral width can increase translocation time of DNA up to 107, 62 and 15 %. Also, strong plasmon field can trap the DNA molecule in the nanopore. The suggested method can be utilized to solve the fast-translocation challenge of the nanopore DNA sequencers.
Preparation and characterization of highly efficient and stable visible-light-responsive photocatalyst AgBr/Ag 3 PO 4

AgBr/Ag3PO4 photocatalyst was synthesized using a facile coprecipitation method. The photocatalyst was characterized by Xray powder diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) surface areas, and photoluminescence (PL) technique. The activity of the photocatalyst was evaluated by the degradation of methyl orange (MO) and rhodamine B (RhB). The results showed that the prepared AgBr/Ag3PO4 exhibited excellent performance and much higher photocatalytic activity than the single one under visible-light irradiation. The optimum mole ratio of Br/P in AgBr/Ag3PO4 samples is 0.3. The prepared AgBr/Ag3PO4 photocatalyst was transformed to Ag/AgBr/Ag3PO4 system with excellent property and good stability in the photocatalytic process. The possible mechanisms of the enhanced photocatalytic activity for the AgBr/Ag3PO4 were also discussed in detail.
Flame Leading Edge and Flow Dynamics in a Swirling, Lifted Flame

Flames in high swirl flow fields with vortex breakdown often stabilize aerodynamically in front of interior flow stagnation points. In contrast to shear layer stabilized flames with a nearly fixed, well-defined flame attachment point, the leading edge of aerodynamically stabilized flames can move around substantially as a result of both the inherent dynamics of the vortex breakdown region and externally imposed oscillations. Motion of this flame stabilization point relative to the flow field may have an important dynamical role during combustion instabilities, as it creates flame front wrinkles and heat release fluctuations. For example, a prior study has shown that nonlinear dynamics of the flame response at high forcing amplitudes were related to these leading edge dynamics. This heat release mechanism exists alongside other flame wrinkling processes, arising from such processes as shear layer rollup and swirl fluctuations. This article describes an experimental investigation of flow forcing effects on the dynamics of the leading edge of a swirl stabilized flame. Flame and flow dynamics were characterized using high-speed particle image velocimetry (PIV) and CH* chemiluminescence imaging. A range of forcing conditions was achieved by varying the forcing frequency, amplitude, and acoustic field symmetry. These results show that the flame leading edge motion is dominated by the natural flow instabilities, particularly the precession of the recirculation zone around the centerline. The fluctuations in leading edge motion at the excitation frequency are much smaller than these natural motions, but are still on the order of the fluid particle displacement associated with the external excitation, indicating that they exhibit an important influence on local flame wrinkling and heat release. Flame response modeling shows that the global, spatially integrated heat release response is controlled by three factors—vortical disturbances, acoustic flow disturbances, and flame leading edge motion. The vortical flow motions dominate the flame response, and the flame leading edge motion is a minor contributor to the overall heat release response. This is an important result, as it shows that the significant motions of the flame leading edge actually have little dynamical significance for understanding the spatially integrated, forced response of the flame.
Efficiency of Cobalt Ferrite and Modified Cobalt Ferrite Magnetic Nanoparticles in Removal of Direct Red 23 from Aqueous Solutions: Isotherm and Adsorption Study

Background & objectives: Discharge of dye containing effluent into water resources can pose hazardous effects to the environment and human health because of their carcinogenic, mutagenic, and toxic nature. The present research was performed to study the efficiency of cobalt ferrite magnetic nanoparticles and its modified type in removing Direct Red 23 from aqueous solutions. Methods: In this applicable study magnetic nanoparticle of cobalt ferrite and modified cobalt ferrite were synthesized. Direct Red 23 dye was selected as a model to evaluate decolorization potential of the adsorbent. The effects of parameters such as initial dye concentrations (50-200 mg/L), adsorbent dose (0.1-0.4 g/L), pH (2-10) and the effect of inorganic salts (NaCl, Na2SO4, NaHCO3 and Na2CO3) on the adsorption process were also studied. Longmuir, Freundlich, and Tempkin isotherm models were applied for data evaluation. Results: Maximum efficiencies of cobalt ferrite magnetic nanoparticles and modified cobalt ferrite magnetic nanoparticles for dye removal were 14.45 and 81%, respectively. The maximum adsorption capacity of modified cobalt ferrite magnetic nanoparticles for Direct Red 23 was 188.6792 mg/g of adsorbent. Adsorption of dye on modified adsorbent followed Langmuir isotherm. Conclusion: Based on the obtained results, it is concluded that modified cobalt ferrite magnetic nanoparticles can be used as an effective adsorbent for removal of Direct Red 23 form colored effluents.
Foreign Direct Investment Inflows And Economic Performance In A Developing Economy: Nigerian Evidence

Motivated by the need for a classified and comparative analysis of the effects of oil related and non-oil related foreign direct investments on Nigeria’s economic growth, this study evaluates secondary data obtained from Central Bank of Nigeria's Statistical Bulletin over the period 1981 to 2016 (36 years). Statistical techniques, which include Stationarity, Multiple Regression, Johansen's Co-integration, Error Correction Estimations and Granger Causality tests, were employed to evaluate the prevailing inter-relationships as well as the extent to which these classified foreign direct investment inflows do promote, and/or support Nigeria's economic growth. On the whole, the results of this study show that irrespective of the prevalence of significant long run relationship among the study variables, both the short and long run estimations as indicated by the multiple regression and error correction estimates, provide compelling evidences of significant sensitivities of Nigeria’s economy to only variations in non-oil related FDI inflows. However, the Granger Causality test results indicate significant prevalence of two unidirectional causalities between Nigeria’s GDP and both oil and non-oil related FDI inflows with Causality flowing from oil and non-oil related FDI to the GDP in both cases. Because of the greater sensitivity of Nigeria’s GDP to non-oil related FDI inflows compared to oil related FDI inflows, the study concludes that non-oil related FDI inflows are more beneficial to Nigeria's economy compared to oil related FDI inflows. Consequently, it is recommended that both Nigeria's private sector entrepreneurs and the government should make further efforts to market and attract more foreign direct investors in the non-oil related sector of the Nigerian economy in order to maximize business opportunities in the non-oil sector of Nigeria’s economy as well as aid diversification in Nigeria’s economy.

Analysis of Price Transmission of Fresh Tomato and Pineapple in the Rural and Urban Markets of Akwa Ibom Sate, Nigeria

The study investigated the dynamics of price transmission and market integration of fresh tomato and pineapple in the rural and urban markets of Akwa Ibom State, Nigeria. Average monthly prices (measured in naira per kilogram) of fresh tomato and pineapple in the rural and urban markets were used in the analysis. The data was obtained from the quarterly publications of the Akwa Ibom State Agricultural Development Programme (AKADEP). The data covered the period from January 2005 to September 2013. The trend analysis showed that, prices of fresh tomato and pineapple in the rural and urban markets have positive significant relationships with time and positive exponential growth rate. The Pearson correlation coefficient of each of the respective pair of rural and urban price of fresh tomato and pineapple revealed significant positive and symmetric relationships. The bivariate Granger causality test revealed bi-directional relationships between the rural and urban price of fresh tomato and pineapple in the State. The co-integration test revealed the presence of co-integration between the rural and urban price of fresh tomato and pineapple. The coefficients of market integration in the rural and urban price equation display varied degrees of long run market integration. The results of the error correction model (ECM) confirmed the existence of the short run market integration between the rural and urban prices of fresh tomato and pineapple in the study area. The urban price of fresh tomato adjusted faster to the stable state in the long run than its respective rural price. Also the rural price of pineapple adjusted faster to a stable state in the long run than its respective urban price. The index of market connection for fresh tomato and pineapple supported the existence of the short run market integration between the rural and urban markets. Based on the findings, it is recommended that, the Akwa Ibom State government should continue to provide marketing infrastructures in the rural areas to improve the symmetric nature of information among fresh tomato and pineapple markets in the state. Effort should also be channeled by all stake holders such as governments, trade unions and other organizations to reduce excessive externality costs associated with the marketing of fresh tomato and pineapple in the state. The government of Akwa Ibom State should established market information centers and awareness programmes on mass media to facilitate efficient information flow among fresh tomato and pineapple producers and consumers in the state.
A search for radio emission from exoplanets around evolved stars

The majority of searches for radio emission from exoplanets have to date focused on short period planets, i.e., the so-called hot Jupiter type planets. However, these planets are likely to be tidally locked to their host stars and may not generate sufficiently strong magnetic fields to emit electron cyclotron maser emission at the low frequencies used in observations (typically >= 150 MHz). In comparison, the large mass-loss rates of evolved stars could enable exoplanets at larger orbital distances to emit detectable radio emission. Here, we first show that the large ionized mass-loss rates of certain evolved stars relative to the solar value could make them detectable with the LOw Frequency ARray (LOFAR) at 150 MHz (lambda = 2 m), provided they have surface magnetic field strengths >50 G. We then report radio observations of three long period (>1 au) planets that orbit the evolved stars beta Gem, iota Dra, and beta UMi using LOFAR at 150 MHz. We do not detect radio emission from any system but place tight 3 sigma upper limits of 0.98, 0.87, and 0.57 mJy on the flux density at 150 MHz for beta Gem, iota Dra, and beta UMi, respectively. Despite our non-detections these stringent upper limits highlight the potential of LOFAR as a tool to search for exoplanetary radio emission at meter wavelengths.
