Bilateral incomplete-information negotiations of multiple issues present a difficult yet common negotiation problem that is complicated to solve from a mechanism design perspective. Unlike multilateral situations, where the individual aspirations of multiple agents can potentially be used against one another to achieve socially desirable outcomes, bilateral negotiations only involve two agents; this makes the negotiations appear to be a zero-sum game pitting agent against agent. While this is essentially true, the gain of one agent is the loss of the other, with multiple issues, it is not unusual that issues are valued asymmetrically such that agents can gain on issues important to them but suffer losses on issues of less importance. Being able to make trade-offs amongst the issues to take advantage of this asymmetry allows both agents to experience overall benefit. The major complication is negotiating under the uncertainty of incomplete information, where agents do not know each other's preferences and neither agent wants to be taken advantage of by revealing its private information to the other agent, or by being too generous in its negotiating. This leaves agents stumbling in the dark trying to find appropriate trade-offs amongst issues. In this work, we introduce the Bilateral Automated Mediation (BAM) framework. The BAM framework is aimed at helping agents alleviate the difficulties of negotiating under uncertainty by formulating a negotiation environment that is suitable for creating agreements that benefit both agents jointly. Our mediator is a composition of many different negotiation ideas and methods put together in a novel third-party framework that guides agents through the agreement space of the negotiation, but instead of arbitrating a final agreement, it allows the agents themselves to ratify the final agreement.

The purpose of this study was to examine the mediators' views on their work; mediation by reason of the breach. The starting point was to find out the mediator's approach and attitude in relation to the perpetrator and victim, and the prevailing regulatory framework. After review of the literature, we came to the realization that knowledge of this area was very limited and thus presents an unexplored topic. It emerged from the results that the mediators emphasize the importance of maintaining impartiality and neutrality in the process of mediation and that it is important to create a good relationship with both parties. The methods used by the mediators is not so different much about, but the mediators apply Crime Prevention Council handbook. Since mediation is a rather lonely profession when they are not very many, are the mediators to network with other municipalities to exchange experiences and knowledge and through this develop their professional role and mediation activities.

The production of enantiopure compounds can be achieved by using dehydrogenases as biocatalysts catalyzing reduction reactions of prochiral compounds such as ketones, aldehydes and nitriles. These dehydrogenases are cofactor dependent enzyme where cofactor is Nicotinamide dinucleotite having some restrictions that limits usage of dehydrogenases in organic synthesis including instability of cofactor in water and high cost. Therefore suitable regeneration method is needed and developed which are enzymatic and electrochemical. We will use an electrochemical approach for the regeneration of reduced co-factors which has been shown in principal with mediators like pentamethylcyclopentadienyl rhodium bipyridine complexes or ferrocenes. This project is European Union project, whose name is Development of Electrochemical Reactors Using Dehydrogenases for Enantiopure Synthon Preparations. All active compounds / mediator, cofactor and enzyme, will be immobilized on the electrode surface of the constructed reactor surface. Therefore only educts and v products will exist in the reactor medium. A gas diffusion electrode will be employed as a counter electrode / which delivers clear protons to the system. Mediator will carry electrons to the cofactor for cofactor regeneration. Then enzyme will use the cofactor and convert substrates to the product in high stereoselectivity. Our part in this project is the synthesis of mediator and suitable linkers for enzyme, cofactor and mediator immobilization. In the first part of the study, Linkers which contain thiol group and disulfide linkage were synthesized because working electrode made of by gold nano particles and immobilization carried out by the help of these groups on gold nano surface. In the second part of the study, mediators were synthesized which are pentamethylcyclopentadienyl rhodium bipyridine complexes and ferrocene derivatives. Synthesized mediators were reacted with linkers by using Click Chemistry and by imine formation in order to convert mediator to the thiol functionalized form.

The growth of service industry enhances the importance of emotion issues in organizations. In the light of increasing interest in organizational emotions, previous studies focused on how front line staffs work. However, employees who play mediating role perform more emotional labor. As Arvey, Renz and Watson (1998) suggested, it is valuable to investigate the possible moderating or mediating roles valuable. By interviewing fifteen advertising account people, this article discusses the emotional labor of advertising account people who mostly play mediating role at work. Analyzing transcriptions in a qualitative approach, this research explores the emotional rules of mediating role and how they are socialized.

This PhD work was partially supported by the European LIREC project (Living with robots and interactive companions) a collaboration of 10 EU partners that aims to develop a new generation of interactive and emotionally intelligent companions able of establishing and maintaining long-term relationships with humans. The project takes a multi-disciplinary approach towards investigating methods to allow robotic companions to perceive, remember and react to people in order to enhance the companion’s awareness of sociability in domestic environments. (e.g. remind a user and provide useful information, carry heavy objects etc.). One of the project's scenarios concerns remote human-human communication enhancement utilising autonomous robots as social mediators which is the focus of this PhD thesis. This scenario involves a remote communication situation between two distant users who wish to utilise their robot companions in order to enhance their communication and interaction experience with each other over the internet. The scenario derived from the need of communication between people who are separated from their relatives and friends due to work commitments or other personal obligations. Even for people that live close by, communication mediated by modern technologies has become widespread. However, even with the use of video communication, they are still missing an important medium of interaction that has received much less attention over the past years, which is touch. The purpose of this thesis was to develop autonomous robots as social mediators in a remote human-human communication scenario in order to allow the users to use touch and other modalities on the robots. This thesis addressed the following research questions: Can an autonomous robot be a social mediator in human-human remote communication? How does an autonomous robotic mediator compare to a conventional computer interface in facilitating users’ remote communication? Which methodology should be used for qualitative and quantitative measurements for local user-robot and user-user social remote interactions? In order to answer these questions, three different communications platforms were developed during this research and each one addressed a number of research questions. The first platform (AIBOcom) allowed two distant users to collaborate in a virtual environment by utilising their autonomous robotic companions during their communication. Two pet-like robots, which interact individually with two remotely communicating users, allowed the users to play an interactive game cooperatively. The study tested two experimental conditions, characterised by two different modes of synchronisation between the robots that were located locally with each user. In one mode the robots incrementally affected each other’s behaviour, while in the other mode, the robots mirrored each other’s behaviour. This study aimed to identify users’ preferences for robot mediated human-human interactions in these two modes, as well as investigating users’ overall acceptance of such communication media. Findings indicated that users preferred the mirroring mode and that in this pilot study robot assisted remote communication was considered desirable and acceptable to the users. The second platform (AiBone) explored the effects of an autonomous robot on human-human remote communication and studied participants' preferences in comparison with a communication system not involving robots. We developed a platform for remote human-human communication in the context of a collaborative computer game. The exploratory study involved twenty pairs of participants who communicated using video conference software. Participants expressed more social cues and sharing of their game experiences with each other when using the robot. However, analysis of the interactions of the participants with each other and with the robot show that it is difficult for participants to familiarise themselves quickly with the robot while they can perform the same task more efficiently with conventional devices. Finally, our third platform (AIBOStory) was based on a remote interactive story telling software that allowed users to create and share common stories through an integrated, autonomous robot companion acting as a social mediator between two people. The behaviour of the robot was inspired by dog behaviour and used a simple computational memory model. An initial pilot study evaluated the proposed system's use and acceptance by the users. Five pairs of participants were exposed to the system, with the robot acting as a social mediator, and the results suggested an overall positive acceptance response. The main study involved long-term interactions of 20 participants in order to compare their preferences between two modes: using the game enhanced with an autonomous robot and a non-robot mode. The data was analysed using quantitative and qualitative techniques to measure user preference and Human-Robot Interaction. The statistical analysis suggests user preferences towards the robot mode. Furthermore, results indicate that users utilised the memory feature, which was an integral part of the robot’s control architecture, increasingly more as the sessions progressed. Results derived from the three main studies supported our argument that domestic robots could be used as social mediators in remote human-human communications and offered an enhanced experience during their interactions with both robots and each other. Additionally, it was found that the presence of intelligent robots in the communication can increase the number of exhibited social cues between the users and are more preferable compared to conventional interactive devices such as computer keyboard and mouse.

<p>This study entails a constructive contribution towards a contemporary reinterpretation, within the Akan context, of the classic Christian notion of Christ&rsquo / s person and work as Mediator between God and humanity. Specifically, I endeavour to reinterpret aspects of the Christian confession of faith as formulated by the Council of Chalcedon (451) that, Jesus Christ is &ldquo / truly God&rdquo / (vere Deus) as well as &ldquo / truly human&rdquo / (vere homo). I build on the notion that the relationship between these two claims may also be understood in terms of the one &ldquo / person&rdquo / and the two &ldquo / natures&rdquo / of Jesus Christ. The work of Christ is reinterpreted from this perspective. The thesis is divided into two main parts. The first part, which covers the first four chapters, entail reviews of some of the dominant African Christologies &ndash / with particular reference to divine conqueror and ancestor Christologies. In these chapters, the adequacy of the mentioned Christologies is assessed with reference to the Nicene/Chalcedonian confessional definition concerning the person of Christ. The conclusion reached is that these Christologies do not adequately express the person of Christ as truly divine as well as truly human as defined by the first four ecumenical councils. As a result, these Christologies also express the work of Christ, particularly his atonement in a less adequate way.</p>

<p>Violence is considered to be one of the most critical and threatening global problems plaguing the world today, leaving a trail of devastating consequences to societies, economies, cultures, families and individuals (Desjarlais &amp / Kleinman, 1997). Adolescents who grow up in a context of violence learn distorted ways of thinking, acting, living and interacting. Aggressive tendencies and violent behaviour become internalised and adopted as acceptable ways to resolve conflict situations. Chronic, continuous exposure to violence results in physical, psychological and emotional disturbances, such as depression, anxiety, lowered self-confidence, sleep disturbances, decreased attention and concentration spans. This study addressed the form of violence known as community violence, i.e. violence that children experience within their communities (either as witnesses or as victims). This study investigated the effects of this negative environmental experience and investigated potential mediating and moderating variables that could influence the harmful effects of such experiences. The variables considered as mediating and/or moderating variables were social support and self-esteem. The theoretical framework adopted for this study was Bronfennbrenner&rsquo / s Bioecological Systems theory.</p>

A novel electrode was constructed and tested in a bio-battery. This configuration consisted of a composite electrode with immobilized bacteria (Escherichia coli K-12) in the anode and a composite electrode with immobilized Carbon Nanoparticles (CNP) and algae (Chlorella vulgaris/Scenedesmus sp.) suspended in the cathode. The composite electrode consisted of three parts: a 304L stainless steel mesh base, an electro-polymerized layer of pyrrole, and an electro-polymerized layer of methylene blue. The bacteria were immobilized on the anode electrode using a technique incorporating CNP and a Teflontm emulsion. The anode and cathode electrodes were tested separately in conjunction with chemical cathodes and anodes respectively. The composite electrode with immobilized bacteria was tested in a bioanode setup. The cathode chamber of the cell contained a potassium ferricyanide and buffer solution with a graphite electrode. Factors affecting electrode performance, such as Teflontm and carbon nanoparticle concentration, were investigated to find optimum values. The maximum power density generated by the composite electrode with immobilized bacteria and a chemical cathode was 378 mW/m2. This electrode configuration produced approximately 69% more power density and 53% more current density than composite electrodes with bacteria suspended in solution. Electrochemical Impedance Spectroscopy analysis determined that a significant portion of the bio-battery’s resistance to charge transfer occurred at the surface of the anode and this resistance was significantly lowered when using immobilized bacteria (51% lower than bio-batteries with suspended bacteria). Similarly, biocathodes containing composite electrodes coated with CNP were tested using two algae species, Chlorella vulgaris and Scenedesmus sp., suspended in solution. This electrode configuration was compared with composite electrode without CNP coating. The anode chamber contained potassium ferrocyanide solution with a graphite counter electrode. The composite electrode with CNP produced approximately 23% more current density than composite electrode without CNP. A complete bio-battery was designed using a composite electrode with immobilized bacteria anode and a CNP coated composite electrode with algae suspended in the cathode. EIS analysis showed that the resistance was higher in the biocathode than in the bioanode and a significant portion of the ohmic resistance was contributed by the membrane.
