Reallocation gains in a specific factors model with firm heterogeneity

We study firm heterogeneity in a specific factors model to address the effect of factor mobility on reallocation gains from trade. A model is proposed with Melitz type firm heterogeneity with two sectors, two countries and two fixed factors and one factor mobile across sectors. Equilibrium in each sector can be concisely represented by a demand and supply equation and a FE and ZCP condition. Varying the substitution elasticity between the fixed and mobile factor we show that the welfare gains from trade liberalization are larger in countries with a lower substitution elasticity. Furthermore, it is shown that the immobile production factor in the comparative disadvantage sector can still gain from trade liberalization due to the reallocation effect.
Ability, Motivation and Opportunity as Determinants of Green Human Resources Management Innovation

The buzzing world of sustainability has led to soaring growth of literature on green marketing, green accounting, green retailing, green supply chain management and green general management. Green Human Resource Management (GHRM) studies on how this field contributes to preserving the environment is hardly found. The polarization between "Best fit" and best practice in HRM make difficult to measure human resource management output. Drawing on the classical Ability Motivation Opportunity (AMO) framework emphasizing the necessity of employees to possess abilities, motivation and be given opportunity to perform, Structural Equation Modelling (SEM) is used to spot the terrain for further study on green human resources management as an innovation in Malaysian setting. As most innovations are related to product development, this study highlights GHRM practices as a process innovation in responding to the current trend shifting from pro-economic to pro-social then pro-environment. This way, under the AMO concept, this study scrutinizes the necessity to initiate GHRM practices in manufacturing companies of Malaysia as a process innovation by integrating people, process, technology and the organization. Finally, the model is expected to support the recent National Green Policy.

In this study, the model introduced by Deng (2009) in a sample of 113 manufacturing-business companies units at industrial city of abbas abbad of tehran was reviewd using structural equation modeling through partial least squares method. The findings suggest Packaging and its factors affect willingness to buy the product. (β=0.290). Packaging Factors and its dimensions is effective on cognitive - perceptual Approach. (β=0.346). Cognitive - perceptual approach affect the desire to buy the product. (β=0.327). The desire to buy a product on product affects selection. (β=0.330). The results also show that willingness to buy the product is not effective based on word of mouth advertising.
On the internal vorticity and density structures of miscible thermals

Abstract Miscible thermals are formed by instantaneously releasing a finite volume of buoyant fluid into stagnant ambient. Their subsequent motion is then driven by the buoyancy convection. The gross characteristics (e.g. overall size and velocity) of a thermal have been well studied and reported to be self-similar. However, there have been few studies concerning the internal structure. Here, turbulent miscible thermals (with initial density excess of 5 % and Reynolds number around 2100) have been investigated experimentally through a large number of realizations. The vorticity and density fields were quantified separately by particle image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) techniques. Ensemble-averaged data of the transient development of the miscible thermals are presented. Major outcomes include: (i) validating Turner’s assumption of constant circulation within a buoyant vortex ring; (ii) measuring the vorticity and density distributions within the miscible thermal; (iii) quantifying the effect of baroclinicity on the generation and destruction of vorticity within the thermal; and (iv) identifying the significantly slower decay rate of the peak density as compared to the mean.

The Processes by Which Perceived Autonomy Support in Physical Education Promotes Leisure-Time Physical Activity Intentions and Behavior: A Trans-Contextual Model

The trans-contextual model proposes that young people's perceived autonomy support in physical education will affect their perceived locus of causality, intentions, and physical activity behavior in leisure time. High school students completed measures of perceived autonomy support and perceived locus of causality in physical education. One week later, participants' perceived locus of causality and constructs from the theory of planned behavior were assessed in leisure time. Leisure-time physical activity behavior was measured 5 weeks later. Perceived autonomy support in physical education affected leisure-time physical activity directly and indirectly through a motivational sequence involving internal perceived locus of causality, attitudes, perceived behavioral control, and intentions. Results support the trans-contextual model indicating that perceived autonomy support in an educational context influences motivation in a leisure-time context.

Earnings Per Share Versus Cash Flow Per Share as Predictor of Dividend; Evidence from Non Financial Sector of Pakistan

This research study has compared the relative predictive power of earnings and cash flow in order to find out the best predictor of dividend. This study has used panel data techniques and the data has been collected from the balance sheet analysis of 104 KSE-100 index non-financial companies. This study has employed a linear mixed effect model approach to investigate the main problem. The two models (earnings based model and cash flow based model) have been compared by using log likelihood estimator and Akaiki information criteria (AIC). The results have shown that cash flow per share is a better predictor of dividend than earnings per share in term of log likelihood estimator and Akaiki information criteria (AIC). The results have also concluded that both earnings per share and cash flow per share have a significant relationship with dividend. The study also finds out that all the control variables including firm’s size (SIZE), leverage ratio (LR), market to book value (MBV) and liquidity ratio (LIQ) have a significant relationship with dividend. Keywords: Earning per share (EPS), Cash flow per share (CFPS), Dividend, Linear mixed effect model, Log likelihood estimator, Akaiki information Criteria (AIC) and KSE-100 index
The Effects of Cosmopolitanism on Consumer Ethnocentrism, Product Quality, Purchase Intentions and Foreign Product Purchase Behavior

The purpose of this study is to investigate the effects of consumer cosmopolitanism on domestic vs. foreign product purchase behavior in three categories of consumer products (alcohol products, clothes, furniture). We develop a conceptual model and identify three additional constructs for foreign purchase behavior, i.e., consumer ethnocentrism, product quality and purchase intentions. The measurement model is examined using a data set of 271 and 261 consumers in Estonia and Slovenia, and tested via structural equation modeling. Study confirms the direct effect of consumer cosmopolitanism in foreign purchase behavior, but rejects the direct relationship between cosmopolitanism and product quality.
A Novel Approach for Earthing System Design Using Finite Element Method

Protection of equipment, safety of persons and continuity of power supply are main objectives of the grounding system. For its accurate design, it is essential to determine the potential distribution on the earth surface and the equivalent resistance of the system. Knowledge of such parameters allows checking the security offered by the grounding system when there is a failure in the power systems. A new method to design an earthing system using Finite Element Method (FEM) is presented in this article. In this approach, the influence of moisture and temperature on the behavior of soil resistivity are considered in earthing system design. The earthing system is considered to be a rod electrode and a plate type electrode buried vertically in the ground. The resistance of the system which is a very important factor in the design process is calculated using FEM. FEM is used to estimate the solution of the partial differential equation that governs the system behavior. COMSOL Multiphysics 4.4 which is one of the packages that work with the FEM is used as a tool in this design. Finally the values of the resistance obtained by COMSOL Multiphysics are compared with the proven analytical formula values for the ground resistance in order to prove the work done with COMSOL Multiphysics.
Jurassic Volcanism in the Eastern Pontides: Is it Rift Related or Subduction Related?

The Jurassic volcanic rocks in the centre of the northern zone (south of Trabzon City) provide important constraints on the evolution of Pontides. The investigated volcanic rocks form a transitional series between tholeiitic and calc-alkaline, and is dominated by basalt, basaltic andesite and andesite. Geochemically, they are enriched in LILE and LREE contents and depleted in HFSE [(La/Yb)N= 2.2 - 8.5; (Nb/La)N= 0.1 - 0.77)] compared to mid-ocean ridge basalts and have radiogenic Nd isotope ratios of eNd(210 Ma)= -0.72 to 3.24. These trace element and isotope data suggest that these rocks were derived from low degrees of partial melting of spinel lherzolite that was metasomatized by subduction-related fluids and further underwent a degree of fractional crystallization in magma chambers before being extruded at the surface.
A three-parameter study of external cavity modes in semiconductor lasers with optical feedback

: An analytical study is presented of the so-called external cavity modes in the Lang-Kobayashi equations, which are a system of delay differential equations that model a semiconductor laser subject to conventional optical feedback. Speciﬁcally, the bifurcation set in the space of feedback phase, feedback strength and pump current of the laser is determined. It divides this three-dimensional parameter space into regions with different numbers of physically relevant external cavity modes.
Pairwise Interaction Point Processes for Modelling Bivariate Spatial Point Patterns in the Presence of Interaction Uncertainty

Current ecological research seeks to understand the mechanisms that sustain biodiver- sity and allow a large number of species to coexist. Coexistence concerns inter-individual interactions. Consequently, there is an interest in identifying and quantifying interactions within and between species as reflected in the spatial pattern formed by the individuals. This study analyses the spatial pattern formed by the locations of plants in a commu- nity with high biodiversity from Western Australia. We fit a pairwise interaction Gibbs marked point process to the data using a Bayesian approach and quantify the inhibitory interactions within and between the two species. We quantitatively discriminate between competing models corresponding to different inter-specific and intraspecific interactions via posterior model probabilities. The analysis provides evidence that the intraspecific interactions for the two species of the genus Banksia are generally similar to those between the two species providing some evidence for mechanisms that sustain biodiversity.
The isotopic composition of precipitation from a winter storm – a case study with the limited-area model COSMO iso

Abstract. Stable water isotopes are valuable tracers of the atmospheric water cycle, and potentially provide useful information also on weather-related processes. In order to further explore this potential, the water isotopes H218O and HDO are incorporated into the limited-area model COSMO. In a first case study, the new COSMOiso model is used for simulating a winter storm event in January 1986 over the eastern United States associated with intense frontal precipitation. The modelled isotope ratios in precipitation and water vapour are compared to spatially distributed δ18O observations. COSMOiso very accurately reproduces the statistical distribution of δ18O in precipitation, and also the synoptic-scale spatial pattern and temporal evolution agree well with the measurements. Perpendicular to the front that triggers most of the rainfall during the event, the model simulates a gradient in the isotopic composition of the precipitation, with high δ18O values in the warm air and lower values in the cold sector behind the front. This spatial pattern is created through an interplay of large scale air mass advection, removal of heavy isotopes by precipitation at the front and microphysical interactions between rain drops and water vapour beneath the cloud base. This investigation illustrates the usefulness of high resolution, event-based model simulations for understanding the complex processes that cause synoptic-scale variability of the isotopic composition of atmospheric waters. In future research, this will be particularly beneficial in combination with laser spectrometric isotope observations with high temporal resolution.
Pathogenic Variability and Differential Interaction of Blast Fungus (Pyricularia grisea SACC.) Isolates with Finger Millet Lines in Nepal

To understand the pathogenic variability of Nepalese isolates of Pyricularia grisea pathogenic to finger millet and their differential interaction with this millet exotic lines and landraces, an experiment was conducted at Institute of Agriculture and Animal Sciences (IAAS), Rampur, Chitwan during August to October, 2008. Five Pyricularia isolates collected from Lumle, Pokhara, Gulmi, Kabre and Rampur were tested with five landraces Acc#4337, Acc#6202, Acc#456, KLB#184, Kabre and four exotic lines, PR#202, HR#911, SPFM#K2, and GPU#48 which have been used in national finger millet research programme by Hill Crop Research Programme (HCRP), Kabre, Dolakha. The experiment was laid out in 5x 9 factorial completely randomized designs with 4 replications in screen house. Eighteen-day-old seedlings grown in earthen pots were inoculated with a Pyricularia spore suspension (105ml-1) with the hand sprayer. Disease assessment was done in five days after inoculation. The aggressiveness of the isolates was noticed maximum in Pokhara and minimum in Gulmi isolates. Considerable pathogenic variations among the tested isolates were observed, however, no clear cut differential interactions were noticed in the interaction. The exotic lines showed comparatively resistant against the fungus reaction than the landraces. Among the tested lines Gpu#48, showed resistant reaction and Acc#4337 showed susceptible reaction in artificial inoculation.

Measurement Quality in Indicators of Compositions. A Compositional Multitrait-Multimethod Approach

Compositional data, also called multiplicative ipsative data, are common in survey research instruments in areas such as time use, budget expenditure and social networks. Compositional data are usually expressed as proportions of a total, whose sum can only be 1. Owing to their constrained nature, statistical analysis in general, and estimation of measurement quality with a confirmatory factor analysis model for multitrait-multimethod (MTMM) designs in particular are challenging tasks. Compositional data are highly non-normal, as they range within the 0-1 interval. One component can only increase if some other(s) decrease, which results in spurious negative correlations among components which cannot be accounted for by the MTMM model parameters. In this article we show how researchers can use the correlated uniqueness model for MTMM designs in order to evaluate measurement quality of compositional indicators. We suggest using the additive log ratio transformation of the data, discuss several approaches to deal with zero components and explain how the interpretation of MTMM designs differs from the application to standard unconstrained data. We show an illustration of the method on data of social network composition expressed in percentages of partner, family, friends and other members in which we conclude that the face-to-face collection mode is generally superior to the telephone mode, although primacy effects are higher in the face-to-face mode. Compositions of strong ties (such as partner) are measured with higher quality than those of weaker ties (such as other network members).
A Spectrophotometric Evaluation of Color Change in Dental Composites due to Various Beverages by Cielab Technique: An In Vitro Study

Two hundred disc samples (50 disk of each material of 10 mm diameter and a thickness of 2.5 mm) of shade A3 were fabricated by condensing the composite materials into ring shaped Teflon moulds by using Teflon coated instrument. No polishing technique was used to avoid modification of the surfaces,which may have influenced the results. They were divided into 4 groups: Nanocomposite resin -- NC, Nano hybrid composite resin—NH,Nano Ceramic composite – NCC ,Hybrid composite resin— HC The prepared composite disks were placed in distilled water and the specimens were incubated in 100% humidity at 37°C for 24 hours in an incubator. The base line color values [L, A, B] of each specimen were measured with a spectrophotometer according to Commission Internationale d’Eclairage [CIELAB]. The spectrophotometer was calibrated with a standard white card before each group of specimen was measured,and the card was used as a background when measuring all specimens. After baseline color measurements, discs were immersed in staining solutions of tea, coffee, wine, artificial saliva and in distilled water [control] and measurements were made after 1week, 2 week and after 3 weeks. Using the values of L*, A*, B*, differences between the first measurement and the time-dependent measurements were calculated as the color difference values ΔL*, ΔA* and ΔB*. For example, the formula for ΔL* was as follows: ΔL*(t) = L*(t) – L*(0) To derive an overall color change, ΔE(t) at time t was calculated as follows according to CIE : ΔE= [(ΔL*)2+ (ΔA*)2+ (ΔB*2)]1/2 Mean values of the different groups were compared using three way analysis of variance and multiple comparisons of the mean values were done using Tukey– Kramer Post Hoc Tests. In the present study, p < 0.05 was considered as the level of significance. CONCLUSION: Under the conditions of the present in vitro study, following conclusions can be drawn: 1. Tea, coffee, wine used in the present study affect the color stability of tested resin composites and the color changes produced are visually perceptible and not clinically acceptable (∆E > 3.3). 2. Following immersion period of 1 ,2 and 3 weeks it was found to be that the highest value of ∆E was observed in Nano ceramic composite on immersion in tea followed by Hybrid composite in tea. 3. Highest discoloration of Nano hybrid composite was found in coffee after immersion after 3 week. 4. Nano composite showed minium discoloration of all tested composite materials but showed highest discoloration after immersion in tea. It is difficult to entirely correlate laboratory findings with the clinical behavior of any restoration, since a number of factors are at play in oral environment and therefore to find a correlation between clinical studies and lab measurements, further in-vivo clinical assessment will be ideal to conclude.
