This paper aims to study the ability of laccase for decolourisation of reactive dyes in presence and absence of natural and synthetic mediators.

Box–Behnken design was used to optimize the parameters to achieve optimum response value. Preliminary screening using several mediators was performed to evaluate extent of decolourisation for the purpose followed by selection of effective mediators only.

Laccase performs in acidic pH; increase in temperature enhances its activity. Rate of decolourisation depends on laccase and dye concentration, temperature, pH and treatment time. Out of five mediators studied, HBT, BT and VA showed promising results.

Study on decolourisation was conducted for individual dyes. In some cases, dyes are applied in combination which requires further study for authentication of data.

Decolourisation with laccase has been found to be a promising technology in waste water treatment. However, selection of mediator remains a crucial factor.

Reactive dyes are self-hydrolysed over time under natural conditions and extent of decolourisation depends on concentration of dye discharged and time spent. If not decolourised quickly, it imposes restriction on use of river water for irrigation.

In this work, activity of various natural and synthetic mediators alongwith laccase was studied to achieve maximum decolourisation which was not studied earlier.

Symbolical-interaction sociology is useful to mediators and relevant to mediation practice. It explores the elements of everyday social interaction including behavior of disputants during instances of conflict. In particular, Erving Goffman’s frame analysis offers mediators a practical tool useful in assessing and managing both the intellectual and emotional responses of disputants during mediation. Moreover, frame analysis can effectively guide mediators in assisting disputants to reorient their respective responses to each other and to the dispute, thereby enhancing opportunities for meaningful dialogue. In addition, Goffman’s game, drama, and ritual metaphors offer simple but powerful analytic tools guiding mediation clients through terrain which would otherwise be chaotic and overwhelming. Mediators committed to enhancing their practices and researchers in search of a sound theoretical base for effective dispute resolution can benefit substantially by applying these insights to the practice of mediation.

The purpose of this paper is to develop a framework for the manufacturer of a make-to-order company to simultaneously negotiate with multiple customers through mediator to achieve order acceptance decisions (OADs).

The paper developed mathematical models for the manufacturer, as well as customers to revise their offers during negotiations. Moreover, the paper also proposed a method for the mediator to carry out his assigned duties to assist in negotiation. In the decision process, mediator acts as a bridge between the manufacturer and customers to reach an agreement. A numerical example is enumerated to illustrate the working mechanism and superiority of proposed framework as compared to the framework where simultaneous negotiations are carried out without the presence of mediator.

Iterative method of negotiation conducted without mediator leads to delay in reaching agreement as the aspiration level of manufacturer offer and counter-offer of customer will never cross each other. In addition, the party who submits the offer first may suffer as the opponent can take the advantage of his/her offer during negotiation, thereby, derailing the issue of fairness. Introducing mediator between the manufacturer and the customer for their negotiations could overcome these two issues. Numerical analysis clearly illustrates that, in average, the rounds of negotiation to reach an agreement can be reduced by 22 percent using proposed negotiation framework. In addition, the fairness in negotiations can be improved by 33 percent with the incorporation of mediator.

Through continuing research efforts in this domain, certain models and strategies have been developed for negotiation. Iterative method of negotiations without mediator will help neither the manufacturer nor the customer in terms of fairness and negotiations round to reach an agreement. To the best of the author’s knowledge, so far, this is the first instance of research work in the domain of OAD and negotiation framework that attempts to incorporate mediator for simultaneous negotiation between manufacturer and customers on multiple issues simultaneously.

Given limited research about how artisans become integrated into tourism, the purpose of this paper is to investigate the emergence of artisan entrepreneur–mediators who link artisans to tourism in rural areas and small cities in Portugal. Using social embeddedness as a conceptual framework, this paper views artisan entrepreneur–mediators as existing within an entrepreneurial ecosystem. The paper investigates their role within this ecosystem and how social networks influence the artisan entrepreneur–mediators’ roles in connecting artisans to creative tourism.

The paper is based on new (2017 and 2018) empirical evidence developed through two rounds of semi-structured interviews of five artisan entrepreneur–mediators.

This paper finds that artisan entrepreneur–mediators in rural areas or small cities take on multiple roles as networking agents who organize and offer creative tourism experiences, providing the missing link between artisans and tourists. An analysis of the nuances of the operations of these artisan entrepreneur–mediators suggests that high levels of social embeddedness within local rural communities are important in order for these neo-rural entrepreneurs to attain their goals.

Originality lies in the identification of a gap in artisan entrepreneurship literature in a rural context. It is the first time that a critical analysis of artisan entrepreneur–mediators who facilitate the link between artisans and tourism is carried out in terms of social embeddedness, their roles and connections to creative tourism, and types of community engagement.

This study aims to investigate the relationship between perceptions of mediators acting symmetrically (treating parties equally) and transparently (providing an explanation of past or future behavior) with parties’ assessments of the neutrality of their mediator and satisfaction with the mediation process.

This mixed-method study surveyed parties and mediators from 35 naturally occurring mediation sessions at community mediation centers about their perceptions of neutrality, symmetry, transparency and satisfaction.

The results showed that parties overwhelmingly assessed their mediators as acting neutrally. Compared to parties’ assessments of mediator neutrality, mediators rated their own neutrality even higher. Symmetry and transparency were both positively correlated with parties’ assessment of mediator neutrality and also emerged as qualitative themes. Speaking order and talk time did not significantly correlate with perception of symmetry. Overall, symmetry appeared to be a more salient factor in parties’ assessment of mediator neutrality than transparency. Both neutrality and symmetry were positively correlated with party satisfaction with the mediation process, but transparency was not.

The present study provides a foundation for future research in understanding neutrality from both parties and mediators’ perspectives. The primary limitation was a small sample size and possible selection bias in achieving the sample.

The study found that symmetry and transparency are useful strategies for managing party perceptions of mediator neutrality and party satisfaction with the mediation process.

This study is one of only a few empirical research studies that investigated the parties’ perspective of mediator neutrality. The study provides a foundation for future research in understanding neutrality from both parties and mediators’ perspectives.
