Understanding consumers' attitude toward practicing green behavior is vital for business as well as environmental reasons. The purpose of present study is to examine the green practicing concept (reducing, recycling and reusing) in an academic context from affective and cognitive perspective. Sample consisting of 315 university students gathered and analyzed using structural equation modeling technique (SEM). Findings indicate that environmental emotion and environmental cognition were significantly related to consumers' attitude, while attitude had significant impact on consumers practicing green behavior elements namely, reducing, recycling and reusing. Findings of the present study can explain the determinants of practicing green behavior. In addition the findings can be used by public and private sector which encourage pro-environmental behaviors.The present study has improved the understanding from pro-environmental behavior (reduce, reuse and recycling) and its antecedents from attitudinal approach. In addition present study confirms suitability of TRA as theoretical grounding in pro-environmental behavior studies by employing (SEM) which is theory-testing laden technique (Urbach and Ahlemann, 2010).

This paper proposes a novel framework for automated software service composition that can significantly support and enhance collaboration among enterprises in service provision industry, such as in tourism insurance and e-commerce collaborative networks (CNs). Sharing/integration of software services in CNs, as well as interoperation among implemented software services in this industry, are quite challenging. There is currently no machine readable standard notation that can unambiguously define the behavior of the software that implements the business processes, however typically enterprises in service industry formalize the definition of their on-line business services using standard business process modeling notation, such as BPMN. Our proposed framework is founded on service oriented architecture (SOA) paradigm. In the proposed framework, software services implementing on-line business services that are provided by different enterprises will be formally defined, using an extended BPMN notation to capture their semantics and behavior, as well as the WSDL notation to capture their syntax. Furthermore, the syntax, semantics and behavior of these software services will be registered in a service repository for the CN, so service discovery in this framework can go far beyond the current practice of service search by name, and can be even based on actual service behavior. The paper addresses enhancement of automated software service integration in CNs, through the application of the Reo coordination language, which is used to formalize the interaction among the composed services. The main reason for using Reo in this context is that it supports separating the computations needed by software components in an integrated system from their interactions. The suggested framework provides more flexibility and adaptability as well as cost-effectiveness in service composition, as to be supported in collaborative networks.

Abstract. Many factors such as weak partner commitment, lack of proper partners' alignment on interest and values, individualism, lack of flexibility, and loss of autonomy may cause partnership's failures in collaborative networks. Most of these serious causes for conflicts in collaborative networks are rooted in partner's behavior, therefore analyzing and modeling the behavioral aspects of collaborative networks are important to enforce their success. This paper first addresses two kinds of behavior related to collaborative networks including Individual Collaborative Behavior and Network Collective Behavior, and then introduces an approach to measure the comparative individual collaborative behavior of partners in networks.
