In this paper, we use the distributions of order statistics to define functions with the appropriate properties to represent social preferences regarding income distributions. Following the approach of Yaari (1987, 1988), this allows constructing a set of social welfare functions from which the corresponding inequality indices are derived. The obtained measures incorporate diverse normative criteria, with different degrees of preference for equality. The generalized Gini coefficients and the family of indices proposed by Aaberge (2000) are obtained as particular cases. This approach allows interpreting each inequality measure in terms of the statistics computed from a randomly selected sample and the identification of unbiased estimators of the Social Welfare Functions. It also shows that each of the families of inequality indices are obtained from the moments of the order statistics and, therefore, each of the families characterizes any income distribution with finite mean. This characterization is very useful in the case of distributions with heavy tail and pronounced positive skew that shows only a few potential moments.

Fuzzy preference relations are considered and the concept of “fuzzy acyclity” is defined in order to measure their rationality. Such a concept is applied to study the properties of social welfare function in a fuzzy environment. In particular, the existence of non‐irrational aggregation rules is assured, in such a way that they can be used as a group decision aid.

A conceptual and analytical approach is presented to reconcile weak and strong sustainability. It involves a reconsideration of the conception of total capital from an ecological‐economic system perspective. In particular, natural capital is classified into non‐renewable resources, renewable resources that are harvested, and those that are not used in production. Strong sustainability is defined in terms of constant environmental quality. Weak sustainability is characterised by non‐decreasing value of aggregate income and environmental quality, and formalised in terms of a “preference‐based social value function”. Ecosystem resilience and basic human needs are introduced as minimum sustainability requirements, and a “sustainability‐based social value function” is proposed, which is sensitive to potentially irreversible changes at the boundaries of the restricted opportunity space. It implies higher values associated to the trade‐offs between income and the environment than the preference‐based function, and the fact that sustainable development is only feasible if both minimum criteria are fulfilled.

The purpose of this study is to explain the discipline of political economy in terms of the theory of conflict and conflict resolution on social matters. Such a theory arises substantively from the generalized and unique methodological worldview of unity of knowledge found in the Islamic epistemological case.

This paper simply uses this epistemic background without dwelling in details of the Islamic methodological worldview of unity of knowledge. Among the central social issues examined in this paper is that of preservation of peace in terms of pressing issues that complement with the concept of well-being.

The imminent study of political economy of socioeconomic development and United Nations Declaration of Human Rights is explained as a broader concept of peace as organic relational balance between the good and true pursuits of life in terms of common global well-being. Within this purview, analytical examination is made of various theoretical precepts. Within the same goal of peaceful coexistence and global conflict resolution, the official stand of Malaysia in global peace is enunciated.

The paper conveys a critical conceptual idea to debate the scope and approach of political economy of peace, development and law matters. The results of the approach used in this study constitute a major contribution of this paper to scholarship in general and acts as a critique of developmental thought of political economy of peace and law.

The purpose of this paper is to focus on the characteristics, efficiencies and interaction of many alternative market governance modes, by the approach of comparative institutional experimentation.

First, a highly simplified model of market economy is developed, which is embedded in a three‐layer governance structure. Then the model is transplanted into laboratory experimentation, so the characteristics and efficiencies of different governance modes can be identified by observing the subjects' behaviors under them.

The experimental results show that the market with governance structure based on rule is more efficient than the market with governance only based on long relation and based on preference or belief, and the dynamic improvement of governance based on rule has a destructive effect on the governance based on relation and governance based on preference or belief.

These results have profound implications for the development or enhancement of market institutions in transition or developing countries.

The purpose of this paper is to demonstrate how consumers choose among three different options offered by a firm in a monopolistic setting, namely, to buy a standard product with a non-customizable design, to ask the firm to customize a product using the consumer’s ideal design or to do the entire design task by themselves. The authors also investigate how social preference intensity and the possibility of reselling a product influence a consumer’s decision.

The authors develop an analytical (game theoretical) consumer choice framework and incorporate a psychological factor into the model. The authors also empirically validate the analytical findings using simulations.

The authors find that as social preference intensity increases, the number of co-producers can either decrease or increase. The authors offer a closed-form solution and interval graphs showing that when the setup price is large (small), the proportion of the market that chooses to do-it-yourself (DIY) is large (small) and an increase in social preference intensity leads to a decrease (increase) in co-production.

This is the first paper to incorporate a social factor into an economic model in a consumer behavior setting. It is also the first paper to explain how customers’ preferences among possible options, such as DIY (without the firm’s help), co-production (with the firm’s help) and a standard product might change while considering other people’s preferences, as well as given associated costs.

Capitalism is fundamentally an economics of producers that has always served the cause of producers. Its special concern for economizing the production process in the guise of economic efficiency went always in favor of producers at the cost of interests of workers and consumers thereby creating a strong sense of economic deprivation in the conscience of workers and low‐income consumers who generally constitute the majority of the population in almost all the developed countries including the United States of America. It is this growing sense of economic deprivation that can be easily observed, especially in the big cities of the United States of America, as a catalyst for Marxist reaction. The Marxist fruit of Capitalist international economics appeared in the form of cold war within the global economy between the rich and the poor countries. Keeping in view the historical dynamics of Marxist movement, twentieth century Capitalist economists have consciously started to counter the threat of Marxism by incorporating in economics the extensive analysis of issues such as social welfare function, interdependent utility functions, intertemporal utility functions, equity in distribution, unemployment insurance, economic development, labor unionism, full‐employment of labor, economic rents, consumer protectionism etc. in the form of labor economics, public sector economics and development economics. It was no doubt a Capitalists' cleverish attempt to redress the grievances, mainly resulting from market failures, of the economically depressed classes within the Capitalist system. So far problems of the depressed classes could not be solved and are not at all expected to be fully solved within the original Capitalistic framework due to its inherent exploitative tendencies.

The purpose of this paper is to analyze the role of embodied dimensions and relational possibilities of (serious) play at work. It shows how a phenomenological and processual approach can help in developing an integral understanding of (serious) play and its paradox in relation to work and practical wisdom and professional artistry in organizations.

Based on the literature review and phenomenology, the role of embodied dimension, and the nexus of playful practitioners, practices and playgrounds are discussed. Systematically, then the concept of “inter-playing” is proposed as a specific embodied and processual practice. Subsequently, the in-between is shown to be a medium and transrelational nexus for (serious) play that allows a more comprehensive understanding and implications.

Based on the phenomenological and relational approach, the concept of (inter-)play allows an extended understanding of serious play and its paradox as a form of an inter-practice. The mediating in-(ter-)between is revealed as decisive for playful practices and playgrounds in organizations. Serious play is linked to practical wisdom and professional artistry in organizations.

Specific theoretical and methodological implications for exploring and enacting play are offered. It is suggested to take research itself as a form of inter-practice and to enact a more integral epistemology and methodological pluralism, including body-related and art-based approaches and critical issues.

Some specific practical implications are provided that facilitate and enable embodied play and play-spaces in an ongoing, arts-based learning and development process in organizational and educational contexts.

The corporeality of responsive inter-play is seen as connected to sociality and social interaction as self and others are considered as a nexus. In particular, poetic phrónêsis in professional playful practice is linked to social creativity that includes attention and recognition of others and otherness as well as social inclusivity.

By extending the existing discourse and using an embodied approach, the paper proposes a novel orientation for re-interpreting serious play. Equally, it offers the new processual concepts of inter-play and inter-practice that allow more explorations and connections to discourses and practices of phronesis and art(istry).

This paper examines the recent acquisition by Newcastle Polytechnic Library of a computer aided circulation control system. Using the Cost Benefit Analysis methodology (CBA), the costs and benefits of the new system are compared with the previous manual system, particular attention being given to the valuation of students' time. While the CBA approach has many critics, it is basically just an application of traditional economics, i.e. a study of the allocation of resources modified to take account of non‐marketed costs and benefits. As such, it can be a useful guide to policymakers through the identification and evaluation of ‘external’ costs and benefits of alternative projects. External effects which the organisation's accounting methods might otherwise ignore. The study, though subject to errors of omission and misinterpretation (which are inevitable given the complexity of the project and the limited resources available to the analyst), showed that the resource costs of the new installation exceeded the benefits by £33,000 — discounted over a projected life of five years. The major factors influencing this conclusion were: the high cost of ‘in house’ computer programming, and the relatively small saving of user time. A more sophisticated computer with the capacity to hold ‘online’ information on the current state of the book stock could have had a significant impact on the time taken to borrow an item. This would have increased the benefits to users (and possibly encouraged a rise in demand) which may have been sufficient to offset the additional capital costs.

There is growing evidence examining mindfulness-based interventions (MI) for people with intellectual disabilities (IDs). As discussed in this paper, MI may be particularly suited for people with ID given high rates of difficulties in identifying and regulating emotions and as this approach may rely less on cognitive ability compared to other therapies. This study aims to assess the acceptability and preliminary effectiveness of a six-session MI group [the Coping Well Group (CWG)] delivered within routine clinical practice.

Six separate cohorts (n = 25) of adults with ID attended CWG. Quantitative data were collected from service users, including a pre- and post-quality of life (QoL) measure and qualitative data from group facilitators.

Roughly one-half (53%) of service users invited to the group attended at least one session, with low levels of dropout observed among group attendees. A significant improvement in QoL was reported demonstrating a small effect (d = 0.46, p = 0.022) after attending the group. Most service users (72%) were referred to the CWG for help managing difficult emotions. One-half (44%) of attendees required individual therapy after attending the group. Limitations of the evaluation and potential future research are discussed.

The current evaluation contributes a practice-based service evaluation of an MI group for people with ID and mental health difficulties to the currently limited evidence base. To the best of the authors’ knowledge, this is one of the first studies to investigate the impact of group psychological interventions collecting data across cohorts and assessing QoL, a more general measure of well-being than has been used previously.
