Owner's Factor in Value-Based Project Management in Construction

Owner/client is a significant contributing party within the management of a project in construction. In addition to the payment of the bills related to the project, owner/client has duties and responsibilities such as selecting the professionals, making his requirements understood clearly by other parties, making decisions to recommendations and placing orders. Owner/client has to perform these duties and responsibilities at the right times and in correct ways to have the required quality and value for his/her investment. In performing his/her duties and responsibilities owner could introduce positive and negative contributions to the value of the constructed facility. Value-based project management concerns with owner's/client's value system and helps owner/client in performing his/her duties and responsibilities for the optimum positive contributions to the value of the constructed facility in construction. This paper highlights the principles of value-based project management in construction and investigates the impact of owner contributions to the value of a constructed facility in practice.     

An investigation of the role of justice in turnover intentions,job satisfaction,and organizational citizenship behavior in hospitality industry

The relationship of organizational justice perceptions of hotel employees in North Cyprus with various work-related variables was investigated. A total of 208 employees and their managers filled out questionnaires. It was found that distributive justice tended to be a stronger predictor of all of the study variables compared to procedural justice. Findings suggest that the fairness of personal outcomes that employees receive may have more impact on turnover intentions, job satisfaction and organizational citizenship behavior (OCB) than the perceived fairness of a firm's procedures. It was also found that even though improved job satisfaction seems to be related to OCB, organizational justice seems to be the key factor that has a strong effect on both OCB and job satisfaction.     

Optimal replication of contingent claims under portfolio constraints

We determine the minimum cost of super-replicating a nonnegativecontingent claim when there are convex constraints on portfolioweights. We show that the optimal cost with constraints is equalto the price of a related claim without constraints. The relatedclaim is a dominating claim, that is, a claim whose payoffsare increased in an appropriate way relative to the originalclaim. The results hold for a variety of options, includingsome path-dependent options. Constraints on the gamma of thereplicating portfolio, constraints on the portfolio amounts,and constraints on the number of shares are also considered.     

A causal analysis of the impact of information systems and supply chain management practices on operational performance: Evidence from manufacturing SMEs in Turkey

This study has empirically tested a framework identifying the causal links among supply chain management (SCM) and information systems (IS) practices, SCM–IS related inhibiting factors and operational performance based on a sample of 203 manufacturing SMEs operating in the manufacture of fabricated metal products and general purpose machinery within the greater metropolitan area of Istanbul in Turkey. Moderating effect of SCM and IS related enabling factors on the above mentioned relationships is also investigated in this study. Tests of hypotheses indicate that both SCM and IS practices positively and significantly influence the operational performance of sample firms. The results of the structural model also indicate a strong support for negative relationships between SCM–IS related inhibitors and the implementation levels of both SCM and IS practices. Similarly, a strong support was found for the hypothesized negative relationship between SCM–IS inhibitors and operational performance of SMEs. Finally, we verified the moderating impact of SCM–IS enablers on the link between SCM practices and operational performance. A similar moderating impact was also found with regard to the relationship between IS practices and operational performance.     

The day of the week effect on stock market volatility

This study tests the presence of the day of the week effect on stock market volatility by using the S&P 500 market index during the period of January 1973 and October 1997. The findings shown that the day of the week effect is present in both volatility and return equations. While the highest and lowest returns are observed on Wednesday and Monday, the highest and the lowest volatility are observed on Friday and Wednesday, respectively. Further investigation of sub-periods reinforces our findings that the volatility pattern across the days of the week is statistically different.(JEL G10, G12, C22)     

The historical background of tolerance education for blind learners in Cyprus

Tolerance, in its broadest sense, can be understood as accepting all the differences in the society. Some people in society have limitations on certain parts of their bodies or their organs, which can lead to impairment on their physical functioning. Some of these people in society who have disabilities are those who have sight impairments. In order for blind people to be able to function in society in the same manner as other individuals it is possible that they can receive a private education in a similar manner to other people with disabilities. In Cyprus, the first school for the sight impaired was established under the British administration. The institution was opened in Nicosia in 1929 under the initiative of the wife of the Governor Ronald Storss as the St. Barnabas School for Blind Children, where Greek Cypriots and Turkish Cypriots had the opportunity to be educated together. By the end of 1963, the Turkish Cypriot sight impaired children from various regions of the island were educated at St. Barnabas School for the Blind. At the school, English, Greek and Turkish teachers worked together. The main aim of the school was to educate the blind children and reintegrate them into the society. In the present study, information obtained from Blue Book and Cyprus Gazette has been supported by the information compiled from domestic and foreign publications as well as verbal sources. Consequently, it is understood that children in society who became blind for various reasons were educated at the St Barnabas School for Blind Children.

     

Optimal dividend policies with random profitability

We study an optimal dividend problem under a bankruptcy constraint. Firms face a trade‐off between potential bankruptcy and extraction of profits. In contrast to previous works, general cash flow drifts, including Ornstein–Uhlenbeck and CIR processes, are considered. We provide rigorous proofs of continuity of the value function, whence dynamic programming, as well as comparison between discontinuous sub‐ and supersolutions of the Hamilton–Jacobi–Bellman equation, and we provide an efficient and convergent numerical scheme for finding the solution. The value function is given by a nonlinear partial differential equation (PDE) with a gradient constraint from below in one direction. We find that the optimal strategy is both a barrier and a band strategy and that it includes voluntary liquidation in parts of the state space. Finally, we present and numerically study extensions of the model, including equity issuance and gambling for resurrection.     

The effect of firm characteristics in accessing credit for SMEs

Small and medium-sized enterprises (SMEs) play an important role in socio-economic development. Despite their significance, the failure rate for SMEs is considerably high, especially in developing economies. Among the widely pronounced reasons for the high failure rate is non-availability of external financing. This study examines various firm attributes that affect access to credit using a sample of 970 SMEs that operate across nine provinces of Mediterranean and Southeast Anatolia regions in Turkey. The results suggest that asset size, sales volume and stability, export rate, and legal form are important determinants of satisfaction with bank products and services. These results are consistent with the hypothesis that larger firms with high and stable sales revenues are more likely to have better access to and therefore benefit more from credit services offered by their local banks.
