Abstract
We consider a commodity trader that invests in the transportation capacity in order to sell high under the domestic spot market price uncertainty. Hence, the trader faces profit uncertainty that drives the financial distress cost. In our model, the expected financial distress cost is used for the objective in the cases of a value-maximizer firm and a risk-averse agent. Since buying too much transportation capacity affects the market price, we analyze the uncapacitated trading problem and show comparative statics. We discuss how the value maximizer and risk-averse commodity trader’s optimal decisions change in four different cases depending on the pricing of the unit transportation capacity cost: Only risk-neutral, low-mispriced or high-mispriced capacity, and the case with two-measures. Similar to results in literature, only risk-neutral and high-mispriced cases are trivial. However, in low-mispriced and two-measures cases, in which arbitrage opportunities exist, we show that the trader does not invest infinitely due to the financial distress cost.

Abstract
In this research, we examine the relationship between person-organization fit and organizational citizenship behavior via a study conducted at the University of Isfahan, Iran. The study was conducted using the field-descriptive method. Some research hypotheses about the relationship between each of the dimensions of person-organization fit and organization citizenship behaviour were developed and tested. These dimensions include workplace convergence, KSA (knowledge/skills/abilities) congruence, goals congruence, values congruence, and personality congruence, as dimensions of person-organization fit. Statistical population of the research included senior and junior non-academic staff and managers at various levels in the University of Isfahan. A sample size of 132 employees was randomly selected from a total of 184 employees at the different levels using stratified random sampling method. The results revealed that there is a significant relationship between dimensions of person-organization fit and organizational citizenship behavior.
Keywords: Dimensions of person-organization fit, Hypotheses, normality test, factor analysis, structural equation modeling.

Abstract
In this paper, new process capability ratios based on Gini mean difference (GMD) are proposed for both one-sided and two-sided specifications under the assumption that the quality characteristic is normally distributed. The asymptotic sampling distribution for the new proposed PCR is derived along with its plot of probability density function (pdf) for different values of subgroup size and the numerical example is also given. The 100(1 − )% confidence interval for the proposed PCR is computed along with some illustrations.
Keywords: Process capability ratios, natural tolerance limits, specification limits, robustness, efficiency.

Abstract
In this paper, we investigate the possible presence of the behavioural phenomenon in the stock markets of some members of the European Union who are historically known as PIGS (Portugal, Italy, Greece and Spain). We used technical analyses methods and rules to explain behavioural phenomenon in the examined stoch markets. We use different types of moving average technical rules. We perform some further analyses and tests. In our further analyses, we apply standard t-tests in combination with bootstrap methodology under the GARCH (1,1) null model. Overall, the results obtained in the paper show that our technical strategies (buy and hold) “win” the market and that there is a presence of European phenomenon in the PIGS stock markets. In addition, we document significant excess returns for moving average trading strategies and reject the weak-form efficient market hypothesis of Fama (1965).

Abstract
In this research, we examine the impacts of e-service quality, e-satisfaction and e-trust on e-loyalty in online banking. The target population for the research is the population of experienced online banking services users. We took a random sample from this population to collect relevant information or data. Based on the analysis of the data, we found that e-satisfaction and e-trust play major roles in building e-loyalty in the online banking. We also found that e-service quality is not a predictor of e-loyalty in online banking. What these results imply is that e-service quality cannot ensure e-loyalty in online banking. E-loyalty can only be ensured when there is e-satisfaction and e-trust. The limitations of the research were discussed. We also suggested directions for future studies.
Keywords: E-service quality, e-satisfaction, e-trust, e-loyalty, hypotheses, regression analyses.
