A novel approach in risk evaluation for ship-to-ship (STS) transfer of cargo using process failure mode and effects analysis (PFMEA)

The ship-to-ship transfer (STS) of oil and oil products plays currently an important role on a worldwide scale. Usually, it refers to the transfer of cargo between seagoing ships positioned alongside each other. Although the procedure of STS transfer has become a day-to-day practice, it remains a difficult operation, which deserves special consideration. To reduce the adverse effect of a potential accident on humans as well as on the environment, a risk assessment is necessary to be done to evaluate the hazards that derive from such a difficult procedure. To this end, the process failure mode and effect analysis (PFMEA), which is under the umbrella of the traditional failure mode and effect analysis, is properly modified and applied to assess the hazards of a typical STS transfer procedure. PFMEA is based on the risk priority number with regard to each risk related to the procedure of interest by multiplying the numerical values of the severity, occurrence and detection indices. Although PFMEA is currently applied mainly to manufacturing processes, the aim of the paper was to implement this methodology to STS transfer of petroleum products. According to the study of PFMEA implementation, the petroleum cargo is the product similar to the product in a manufacturing procedure; hence, the different phases of the STS procedure are similar to the production line of the manufactured product. Moreover, proposals to eliminate the disadvantages of the implementation of PFMEA by a qualitative manner (using linguistic terms) are proposed. The objective target of this effort is to assess and evaluate the effectiveness of implementing the PFMEA in a maritime activity and therefore to address the advantages and disadvantages of such an approach.     

“Too‐Small‐To‐Survive” versus “Too‐Big‐To‐Fail” banks: The two sides of the same coin

In the recent crisis, the U.S. authorities bailed out numerous banks through TARP, whilst let many others to fail as going concern entities. Even though both interventions fully protect depositors, a bail out represents an implied subsidy to shareholders, which is not yet the case with closures where creditors are not subsidised. We investigate this non‐uniform policy, demonstrating that size and not performance is the decision variable that endogenously determines one threshold below which banks are treated as TSTS by regulators and another one above which are considered to be TBTF. We, hence, provide a pair of economic rather than regulatory cut‐offs for TBTF and TSTS banks. The shareholders and the other uninsured creditors of a distressed bank are not bailed out if the bank is considered to be TSTS. We further document that the less complex a bank is, the less likely is to be bailed out and, hence, to have all of its creditors protected.     

The effect of trust on customer contact personnel strategic behavior and sales performance in a service environment

The involvement of customer contact personnel in the strategy process is a largely unexplored area in both marketing and strategic management. Based on social exchange theory, and in particular, the notion of trust within this context, we examine the nature and extent of strategy participation exhibited by customer contact personnel. Exploring dyadic relationships we found that the extent to which contact personnel trust their supervisors positively influence their willingness to participate in strategic activities. Furthermore, we found that communication and information sharing moderate the relationship between trust and strategic activities. Thus, the more contact personnel are involved in the strategic process, the more likely supervisors are to rate the contact person's selling performance as high.     

Winners and Losers in EU State Aid Policy

Who gains and who loses from the European Union’s state aid policy? Using data published by the Competition Directorate from 1992 to 2007, I employ pooled time series analysis to understand the motives behind state aid allocations and then interpret the findings in light of the political relationship between Member States and the Commission. Demand for aid is shaped by national macroeconomic and institutional characteristics. Governments then bargain with the Commission to allocate aid. As a result, the Commission finds itself in a delicate balancing act as controller of state aids and as an institution subject to the political power of member government.     

Managing mutual funds or managing expense ratios? Evidence from the Greek fund industry

This study examines the expense ratio policy of Greek equity funds operating in a small emerging market with an oligopolistic, bank-dominated financial system. Constructing a unique dataset of non-publicly available expense ratios charged by these funds, we examine the impact these expenses have on funds’ performance and flows. The main conclusion is that funds’ performance is negatively related to their expenses, while investors’ flows are not directly affected by expenses. Furthermore, the funds affiliated with one of the three dominant domestic banking groups achieve higher performance and attract higher net flows in comparison to their competitors.     

Revisiting mutual fund performance evaluation

Mutual fund manager excess performance should be measured relative to their self-reported benchmark rather than the return of a passive portfolio with the same risk characteristics. Ignoring the self-reported benchmark results in different measurement of stock selection and timing components of excess performance. We revisit baseline empirical evidence fund performance evaluation utilizing stock selection and timing measures that incorporate the self-reported benchmark. We introduce a new factor exposure based approach for measuring the – static and dynamic – timing capabilities of mutual fund managers. We overall conclude that current studies are likely to be misstating skill because they ignore the managers’ self-reported benchmark in the performance evaluation process.     

Fishery Products Distribution and Logistics in Greece

Greece has a population of 10.9 million people. The consumption of fish is high (approx. 25kg per capita per year), with many traditional Greek dishes being focused on fish. Fish farming has emerged as one of the fastest growing technologies in Greece and is now the country's third largest export sector and shows great potential for further development. For this reason, fishery products distribution and logistics is an issue of major significance in Greece. This article attempts to analyze the structure of the fishery products distribution and logistics system and identifies major problems within that system. The article is based on the findings of a survey of 186 companies. As one of the first studies in Greece ocusing on fishery products distribution and logistics, it will generate new insights and information for distribution and logistics academics and managers.     

Economic efficiency of Greek retail SMEs in a period of high fluctuations in economic activity: a DEA approach

This study aims to analyse the economic efficiency of Greek small and medium retail enterprises before and after the crisis that started in 2008. Based on the Accounting Equation, we use Data Envelopment Analysis (DEA) to estimate variable returns of scale efficiency scores and to conclude on specific characteristics that efficient companies have, for example, on capital structure. Our results from the DEA application show a high degree of inefficiency. We found that SMEs on the islands are more efficient than those on the mainland and that SMEs in the cities are the least efficient. Size seems to be important, more so on the islands and on the mainland than in the cities. We conclude that companies should act more conservatively in terms of operating cost when the first signs of a recession appear. In addition, during a recession period, companies that have evidences that their operations will continue positively should strengthen their operations by raising more own capital. Finally, our study clarifies four issues: the efficiency of retail companies in a period of growth and a period of recession, focusing on SMEs that operate in different regions, connecting Accounting Equation and DEA and adding acid ratio as an output in our model.     

Particle swarm optimization for optimal product line design

Designing optimal products is one of the most critical activities for a firm to stay competitive. Except for genetic algorithms, previous approaches that solve the optimal product line design problem provide the decision maker with a single best solution. Furthermore, they assume a static market, in which the incumbent firms will not respond to the entrance of a new player. In this paper we apply a new population-based algorithm called particle swarm optimization to the problem and employ a Monte Carlo simulation to compare its performance to that of genetic algorithms. The results indicate that the proposed particle swarm optimization algorithm constitutes an attractive alternative for solving the optimal product line design problem because its performance is comparable to that of genetic algorithms concerning the best solution found while it outperforms genetic algorithms regarding the diversity of the final set of provided solutions. Furthermore, we use concepts from game theory to illustrate how the algorithm can be extended to incorporate retaliatory actions from competitors. The dynamic approach is illustrated through a real-world case in which a firm intends to enter the Greek retail milk market. While employing highly simplifying assumptions, the incorporation of the Nash equilibrium concept provides useful insights, such as the attribute levels that may be resistant to competitive reactions and the incumbent firms that will benefit most in the long term.     

Mandating IFRS in an Unfavorable Environment: The Greek Experience

There is an ongoing debate concerning the efficacy of mandating high-quality accounting standards in unfavorable economies with inadequate institutional infrastructures. Greece provides us with an example of an unfavorable jurisdiction for enforcement of International Financial Reporting Standards (IFRS) due to its code-law tradition, bank orientation, concentrated corporate ownership, poor shareholders' protection, and low regulatory quality. Assuming that these conditions undermine managers' and auditors' incentives for high-quality financial reporting, how likely is it that mandating IFRS in such an environment will be effective? To address this research question, we explore potential effects of IFRS enforcement on two salient properties of accounting income: value relevance and conditional conservatism. Our results indicate only minor improvements in both of them after IFRS implementation.
