The purpose of this paper is to enhance trust in e-commerce multi-agent systems by presenting a model, called RUU, to select the most trustworthy provider agent based on learning from previous interactions and computing reliability, unreliability and uncertainty.

The methodology comprises analyzing the most representative existing trust models, while a new concept was proposed and measured as unreliability. To make decision about the agents, RUU integrated reliability, unreliability and uncertainty components and used the TOPSIS multi-criteria decision method to select the most trustworthy provider agent. To evaluate the RUU model, the experimentation was carried out in two stages. First, the average accuracy of the model was investigated by simulating RUU in a multi-agent environment. Second, the performance of the model was compared with other related trust models.

The experimental results revealed that RUU model outperforms current models in providing accurate credibility measurements and computing an accurate trust mechanism for agents, also presenting a decision-making process to choose the most trustworthy provider agent.

The model presented based on different mathematical computations that take time to be calculated, which is a big limitation of computational models.

RUU enables an agent to make effective and sound decisions in light of the uncertainty that exists in e-commerce multi-agent environments.

This paper is beneficial to enhance the fulfilment of purchasing between provider and requester agents. In fact, the proposed model can ensure critical transactions performed securely in e-commerce multi-agent environments.

Inspectors visiting districts in connection with the Foreign Meat and Unsound Food Regulations have made detailed inquiries in certain instances in regard to local methods of administration of the Sale of Food and Drugs Acts. Special visits for this purpose have also been made to other districts where inquiry appeared to be specially called for. In the course of these inquiries it was found that in some instances the public analyst had made a report to his local authority on some special investigation which had been undertaken in the district respecting a particular article of food, but that copies of such report had not always reached the Board. During an inquiry in the county of Cheshire Dr. Coutts ascertained that the county analyst had made valuable reports in regard to butter and Cheshire cheese of which the Board were unaware. Reports of this nature are of much interest to this sub‐department, and it would be of advantage if local authorities would send to the Board copies of all special reports made by the public analyst.

This article traces the history of a continuous tradition of Marxian stage theory from the beginning of the twentieth century until the present day. The resolution of the first crisis of Marxism was found in the work of Hilferding on finance capital, Bukharin on the world economy and Lenin on imperialism as a new stage of capitalism. Hilferding's, Bukarin's and Lenin's analysis was carried into the post–World War II era through the work of Sweezy and Mandel. A second wave of Marxian stage theorizing emerged with the end of the post–World War II expansion. Mandel's long wave theory (LWT), the Social Structure of Accumulation Framework (SSAF), and the Regulation Approach (RA) analyzed the stagflationary crises as the end of a long wave of growth. This long wave was underpinned by the emergence of a postwar stage of capitalism, which was analogous to the reorganization brought about by monopoly capital at the turn of the century. These new schools were reluctant to predict the non-resolution of the current crisis, thus opening up the possibility of further stages of capitalism in the future. This elevated Lenin's theory of the highest stage to a general theory of capitalist stages. The last decade has seen a substantial convergence in the three perspectives. In general, this convergence has reaffirmed the importance of Hilferding's, Bukarin's and Lenin's (HBL's) initial contributions to the stage theoretic tradition. The article concludes with some thoughts on the necessity of stage theory for understanding of the current period of globalization.

This chapter explores the origins of the theme of competitive advantage in 19th and early 20th century economics. This theme, which forms the core of modern Strategic Management, was a battleground for debates about the value of abstract theory versus observations about real-life events. Intellectual genealogies, citations, and other sources show the central roles played by the University of Vienna and Harvard University. These two institutions strongly influenced the theory of monopolistic competition as well as all three modern views of competitive advantage – the industrial as expressed by Porter, the resource-based as expressed by Penrose, and the evolutionary as expressed by Schumpeter.

This chapter offers an original conceptualization of co-mentoring – situated in the wider literature – together with evidence of its impact and factors facilitating impact across applications of co-mentoring in transnational schooling contexts. Co-mentoring is an alternative to more traditional, hierarchical, and unidirectional approaches to mentoring in education. Extending the extant literature on collaborative mentoring (or “comentoring”), co-mentoring is a collaborative, compassionate, and developmental relationship – informed by specific approaches to mentoring and coaching – that is intended to support participants' professional learning, development, effectiveness, and well-being, and potentially improve their workplace cultures. Detailing three different applications of co-mentoring across the United Kingdom and United States, the chapter evidences the realization of these intended outcomes (professional learning, etc.), and highlights factors found to be instrumental in facilitating the positive impacts of co-mentoring. We end with recommendations for undertaking research and practice that build human and organizational capacity through co-mentoring. A takeaway is that intentional approaches to co-mentoring can have value for participating parties and broader impact, as well as wide applicability.

Ethnoracial categories and classifications can change over time, sometimes leading to increased social mobility for marginalized groups or nonelites. These ethnoracial changes are often attributed to emulation, where nonelites adopt the elite's social, cultural, and political characteristics and values. In some cases, however, nonelites experience ethnoracial shifts and upward mobility without emulating elites, which events can help explain. I argue that the type of event, whether endogenous or exogenous, affects the ability of elites to enforce their preferred ethnoracial hierarchy because it will determine the strategy – either insulation or absorption – they can pursue to maintain their power. I examine this phenomenon by comparing the cases of Irish social mobility in 17th-century Barbados and Montserrat. Findings suggest that endogenous events allow elites to reinforce their preferred ethnoracial hierarchy through insulation, whereas exogenous events constrain elites to employ absorption, which maintains their power but results in hierarchical shifts. Events are thus critical factors in ethnoracial shifts.

Social economics[l] is a small but growing school of thought in the United States. At first sight it appears as if “social economists” are a rather heterogeneous group defying satisfactory description. Yet we believe that there is a unity of focus: a deep concern with human needs rather than just a description of human preferences being co‐ordinated. We define “needs” as “necessary” wants and immediately the question imposes itself: necessary for what? Our answer is human life with its higher or lower qualities. Social economics seeks not only to enable and maintain life, but also to “enlarge” it and fulfil it. As a direct result values are hierarchical, from the lower (survival) values to the highest (ethical, aesthetic) values. Such is implicit in the generally acknowledged human‐values‐orientation of the field, since values can be seen as need satisfiers.

This conceptual paper explores the complex, and neglected, area of mentor development in initial teacher education (ITE) in Australia. It focuses on the emotionality of mentoring, drawing on concepts of emotional labour and emotional intelligence to develop a framework of effective mentoring that helps explain the essence of a mentor’s role in supporting preservice teachers.

This conceptual paper draws together mentor-support practice wisdom and research literature from several relevant areas. It draws on constructive developmental theories and complex stage theory to reaffirm the intricate nature of mentor learning and development. This paper critiques the current utilitarian emphasis on mentoring as a way to improve student outcomes without first having clarity on how to improve mentoring itself.

We introduce the mentoring as emotional labour framework as a way to better understand the nature of mentoring within ITE and as a tool for developing more effective mentor supports. We present “exemplar cases”, which are amalgamations of field observations to illustrate aspects of the framework – however, we do not claim they provide evidence of the utility or accuracy of the framework.

Previous research and policy have tended to gloss over the skills required for effective mentoring, whereas this paper places the emotional labour of mentoring front and centre, explicitly conceptualising and describing the personal and interpersonal skills required in a way that aims to support and empower mentors to recognise existing strengths and areas of potential growth.

We have reprinted the powerful letter addressed to the Daily Mail by MR. H. W. WILSON, the author of “Ironclads in Action,” advocating the immediate adoption of a policy of reprisals for the Zeppelin murder raids. In our view it is the duty of every journal, whatever may be its raison d'être, to assist in keeping the attention of the public fixed upon this matter, to aid in preventing the general feeling of disgust and indignation from cooling down, and to support those who have the brains to understand the nature of the Hun in their efforts to compel the Government to adopt the most effective means at present available to put an end to the murderous excursions of the German vermin into this country. As MR. WILSON points out, the deliberate Hun policy of slaying women, children and non‐combatants is either permitted by the laws of war recognised by civilised nations or it is not permitted by those laws. If it is permitted, “then clearly the Power which refrains from making similar attacks on the enemy's towns, villages, and residential districts, loses greatly from the military standpoint.” If it is not permitted then the only course— “the force behind the laws of War”—is a policy of drastic reprisals. Moreover, it is the only course that the Hun can understand. The methods of “frightfulness” are definitely laid down in the German military system as methods to be ruthlessly followed whenever this can be done with impunity and the fear of reprisals is also definitely laid down as the only consideration which is to be allowed to operate as a check upn “frightfulness.” “The Power which fails to take reprisals when a great offence is committed is as the negligent judge or the faithless jury that acquits a murderer. It sins against humanity … it encourages the criminal in his crime.”
