Normally there is a one-time relationship between stakeholders in the construction projects. Thus, project participants are easily exposed to opportunistic behavior. According to the theory of transaction costs, a contract effectively influence the behavior of counter-party. The important role of contracts in limiting opponent opportunistic behavior has been academically acknowledged and studied in inter-firm relationships. The purpose of this study is to reveal the mediating effect of the contract on the power of the contractor in the contractor's behavior. Power is divided into mediated and non-mediated power. We surveyed construction companies' employees who have conducted construction projects. Based on the questionnaire response, we examined the influence of the Employer's power on the behavior of the contractor. Both non-mediated power and mediated power were significant for in-role and out-role behaviors. Both non-mediated power and mediated power were found to have a significant effect on the control and coordination function of contracts. The results show that the control function of the contract is significant for the in-role behavior and the extra-role behavior. Finally, the mediating effect of the contract function was significant only in the control function.

This research investigates the effect of the antecedents (i.e. specific investment, opportunistic behavior, communications, uncertainty, interdependence, power imbalance, shared value, and flexibility) that influence the trust and commitment of domestic apparel manufacturers toward contractors as well as the effect of trust and commitment on firm performance and relationship satisfaction. A total of 128 apparel manufactures participated in this study. Factor analysis, Cronbach's alpha coefficient, and path analysis were conducted for the statistical analysis. Specific investment, communication, shared value, and flexibility had a positive effect on trust; however, opportunistic behavior had a negative effect. Interdependence, shared value, and flexibility had a positive effect on commitment; however, power imbalance and uncertainty had a negative effect. Trust did not exert an effect on commitment in this research; however, trust and commitment had a positive effect on firm performance; in addition, trust and commitment had a positive effect on relationship satisfaction. The findings offer insight on how to better manage apparel manufacturer-contractor relationships to ensure success.

This study identifies the antecedents of trust in the examination of the effects of the antecedents of trust on trust in apparel manufacturer-contractor relationships. A total of 92 apparel manufactures participated in this study. A factor analysis, Cronbach's alpha coefficient, and multiple regression analysis were conducted for the statistical analysis. Five antecedents of trust were classified: flexibility, opportunistic behavior, communication, specific investment, reputation. Two factors of trust were identified: credibility and benevolence. Flexibility, communication, and reputation of a contractor positively influenced the credibility of an apparel manufacture in a contractor. Flexibility, communication, and specific investment of a contractor positively relate to the benevolence of an apparel manufacture in a contractor. However, the opportunistic behavior of a contractor did not relate to either the credibility of an apparel manufacture or the benevolence in a contractor. The results of this study provide empirical evidence of the impact of flexibility, communication, specific investment, reputation on trust in apparel manufacturer-contractor relationships, and additional insight for selecting contractors that seek to improve trust in apparel manufacturer-contractor relationships.

Delay tolerant networks (DTNs) characterized by the lack of guaranteed end-to-end paths exploit opportunistic data forwarding mechanism, which depends on the hypothesis that nodes are willing to store, carry, and forward the in-transit messages in an opportunistic way. However, this hypothesis might easily be violated by the presence of selfish nodes constrained with energy, bandwidth, and processing power. To address this problem, we propose a practical reputation-based incentive scheme, named PRI, to stimulate honest forwarding and discipline selfish behavior. A novel concept of successful forwarding credential and an observation protocol are presented to cope with the detection of nodes' behavior, and a reputation model is proposed to determine egoistic individuals. The simulation results demonstrate the effectiveness and practicality of our proposal.

In opportunistic network, the behavior of a node is autonomous and has social attributes such as selfishness.If a node wants to forward information to another node, it is bound to be limited by the node's own resources such as cache, power, and energy.Therefore, in the process of communication, some nodes do not help to forward information of other nodes because of their selfish behavior. This will lead to the inability to complete cooperation, greatly reduce the success rate of message transmission, increase network delay, and affect the overall network performance. This article proposes a hybrid incentive mechanism (Mim) based on the Reputation mechanism and the Credit mechanism.The selfishness model, energy model (The energy in the article exists in the form of electricity) and transaction model constitute our Mim mechanism. The Mim classifies the selfishness of nodes and constantly pay attention to changes in node energy, and manage the wealth of both sides of the node by introducing the Central Money Management Center. By calculating the selfishness of the node, the currency trading model is used to differentiate pricing of the node's services. Simulation results show that by using the Mim, the information delivery rate in the network and the fairness of node transactions are improved. At the same time, it also greatly increases the average life of the network.

This paper proposes a bandwidth-aware localized-routing algorithm that is capable of sensing the available spectrum bands within a two-hop neighboring for choosing the highly opportunistic routes. A mixed-integer linear programming (MILP) is utilized to formulate the optimization problem. Then, the proposed algorithm is used to determine the maximum bandwidth possible of link pairs via a bandwidth approximation process of relaxed variables. Thereby, the proposed algorithm can allow selected routes corresponding to maximum bandwidth possible between cognitive radio (CR) users through link pairs in cognitive radio networks. By comparing the solution values to previous works, simulation results demonstrate that the proposed algorithm can offer a closed-optimal solution for routing performance in cognitive radio networks. The contribution of this paper is achieved through approximately 50% throughput utilized in the network.

While strategic alliance of multinational corporation has boost, opportunistic behavior is also increased recently. This study examines the cause of opportunism in strategic alliance by focusing on the development of opportunistic behavior, a process in which resource complementarity and risk perception decides attitudinal direction, ultimately leading to opportunism. Empirical test based on 257 alliance participants shows that risk perception had a greater influence on firms' attitudinal and behavioral directions compared to benefit perception. Notably, relational risk heavily influenced firms' competitive attitude and opportunistic behavior. Finally, the study concludes that firms' competitive and independent attitude caused by risk perception negatively influence alliance outcome. Based on the results, it is drawn that alongside the external tools such as surveillance, control, monitoring or legalistic pleas, management of risk perception during the alliance process has significance influence on the achievement of alliance goals.

The purposes of this study are following. First, we want to review the relationship between trust and precedent variables including shared value, communication and opportunistic behavior in the on-line and off-line channel. Second, building the relationship among variables from previous research, we develop the research model. Third, based on the empirical analysis, we want to build the relationship among variables. Fourth, based on results of analysis, we want to elicit implications for marketing management from the trust in on-line channel in order to enhance the relationship commitment and customer loyalty. Theoretical implications of this study are following. First, under the multiple channel retailing environment, trust in on-line channel is influenced by the trust in off-line channel that the company is operating. Previous researches couldn't found this result because these researches divided on-line and off-line channel separatedly, Second, under the multiple channel retailing environment, on-line or off-line relational attributes including shared value, opportunistic behavior and communication have a effect on trust or relationship commitment So, shared value, opportunistic behavior and communication are very important variables having a effect on trust and relationship commitment in not only off-line channel but also on-line channel. Third, trust and relationship commitment were important mediate variables in multiple channel environment. This result goes with previous researches in single channel.

This study aims to obtain empirical evidence about the cognitive effect of Islamic religiosity and budget control in reducing budgetary slack behavior. This study involved 176 managers as respondents in 10 local companies in Eastern Indonesia. Managers who are respondents in thus study work and are spread across 14 provinces in Indonesia. Probability sampling method has been used for this study from the total population with certain criteria. Data analysis has been done using Warp PLS-SEM technique. The results showed that Islamic religiosity cognitive and budget control had a direct negative effect on budgetary slack behavior. The two variables also fully mediate the relationship between participatory budgeting and budget-based compensation schemes on the behavior of budgetary slack in a negative and significant way. These results mean that the two variables are proven to reduce budgetary slack behavior. This empirical evidence at the same time corrects the agency theory's assumptions about opportunistic human nature and always maximizes every potential economic profit. In addition, the results also show that Islamic religiosity cognitive is stronger in reducing budgetary slack behavior. These results can be used to improve the company's budget control system by incorporating elements that motivate religious goals so that it is more effective in reducing budgetary slack behavior.

This article investigates the problem of distributed channel selection in opportunistic spectrum access networks from a perspective of interference minimization. The traditional physical (PHY)-layer interference model is for information theoretic analysis. When practical multiple access mechanisms are considered, the recently developed binary medium access control (MAC)-layer interference model in the previous work is more useful, in which the experienced interference of a user is defined as the number of competing users. However, the binary model is not accurate in mathematics analysis with poor achievable performance. Therefore, we propose a real-valued one called stochastic MAC-layer interference model, where the utility of a player is defined as a function of the aggregate weight of the stochastic interference of competing neighbors. Then, the distributed channel selection problem in the stochastic MAC-layer interference model is formulated as a weighted stochastic MAC-layer interference minimization game and we proved that the game is an exact potential game which exists one pure strategy Nash equilibrium point at least. By using the proposed stochastic learning-automata based uncoupled algorithm with heterogeneous learning parameter (SLA-H), we can achieve suboptimal convergence averagely and this result can be verified in the simulation. Moreover, the simulated results also prove that the proposed stochastic model can achieve higher throughput performance and faster convergence behavior than the binary one.
