This paper aims to examine the effect of circular economy’s ending of waste on marginal property practices.

This paper utilises doctrinal and theoretical legal analysis, along with theoretical perspectives and qualitative empirical evidence drawn from non-legal academic disciplines.

The current legalistic conception of waste depends on control and value. The indeterminate status of waste as goods at the margins of consumption attracts attention from legal regimes. This process is evidenced by a commercialised treatment of goods at the margins of consumption, limiting the scope of radical marginal property practices such as freeganism (taking goods abandoned by others, to use such goods).

The circular economy aims to end waste. Restriction, and ultimately elimination, of marginal property practices is necessary for circular economy. Freegans will be limited to acting in a “challenge” role, identifying breaches of commercial commodification processes. Control over the use (including disposal) of goods reduces the spaces available for marginal property practices, which in turn raises problematic normative implications for “normal” consumption practices involving waste.

This is the first examination of the impact of circular economy on freeganism. It is also the first sustained application of marginal property theory (van der Walt, 2009) in a legal analysis of circular economy and waste.

The purpose of this paper is to present an approach where a novel user modeling wizard for people with motor impairments is used to gain a deeper understanding of very specific (touch-based and touchless) interaction patterns. The findings are used to set up and fill a user model which allows to automatically derive an application- and user-specific configuration for natural user interfaces.

Based on expert knowledge in the domain of software/user interfaces for people with special needs, a test-case –based user modeling tool was developed. Task-based user tests were conducted with seven users for the touch-based interaction scenario and with five users for the touchless interaction scenario. The participants are all people with different motor and/or cognitive impairments.

The paper describes the results of different test cases that were designed to model users’ touch-based and touchless interaction capabilities. To evaluate the tool’s findings, experts additionally judged the participants’ performance (their opinions were compared to the tool’s findings). The results suggest that the user modeling tool could quite well capture users’ capabilities.

The paper presents a tool that can be used to model users’ interaction capabilities. The approach aims at taking over some of the (very time-consuming) configuration tasks consultants have to do to configure software according to the needs of people with disabilities. This can lead to a wider accessibility of software, especially in the area of gesture-based user interaction.

Part of the approach has been published in the proceedings of the Interactional Conference on Advances in Mobile Computing and Multimedia 2014. Significant additions have been made since (e.g. all of the touchless interaction part of the approach and the related user study).

Discusses diversity in the South African library and information work environment recognising major theories of diversity, and describing diversity provisions in the Constitution, policies and legislation of South Africa. Observes that diversity is not a focus issue in the library and information work environment and speculates that such insignificant attention to diversity could arise from the assumption that existing policies and legislation are sufficient to manage diversity interests. There is also a fear that making an issue on diversity can divide people rather than unite. Recommends that a major research project be conducted on diversity in the library and information workplace to provide insight into the true situation and help in strategizing, planning and intervention.

Suggests that, contrary to his neo‐Kantian methodological intentions, there is much textual evidence that Weber was not consistent in following through the non‐realist epistemology involved. In his search for the methodological bona fides of the empirical social sciences, he focused on the distinctive ontological nature of phenomena that originate in human action. Weber rejected the Homo oeconomicus concept of the agent required by exact theoretical economics. He espoused instead a deeper subjectivist understanding of individual human agents whose actions are shaped by the social complex that confronts them. It was this ontological emphasis that led him to devise the concepts of agent rationality and ideal types as foundations for his empirical inquiries. In these seminal endeavours, though, he understated the contingency of human agency that must be contended with and he fell short in understanding the full extent and influence of the situations within which agents must operate. Nonetheless, it is this focus on the fundamental role of subjective but situated human agency that could still find more of a place in the foundations of social economics.

Approaches to the sociology of culture have largely been constituted around the long tradition of functionalism in sociology. This has hampered the field greatly. Among other shortcomings, this intellectual foundation has led to a limited understanding of ideology and civil society, a conservative political orientation and an overdeterministic view of social action and the actor. In this paper, I explore and then apply a new approach to the sociology of culture, one that attempts to conceptualize more robustly the dynamics of ideology, ideological conflict and civil society. As part of this project, I endeavor to map out a critical cultural perspective that establishes a multidimensional understanding of the contingency of social action.

The prospect that technological and social innovation in the use of communication and information technologies are bringing about an end to sovereignty has been a source of optimism, pessimism and ambivalence. It has captured the popular imagination and it can be found in the anxieties of national leaders about the mingling and collision of cultures and cultural products within and across their borders, and about growing awareness that environmental threats bow to no flag. According to much of this discourse, national governments are becoming increasingly powerless in their battles against real or imagined plights of cultural imperialism (and sub‐imperialism, that is, cultural imperialism within states) and capital mobility, as well as in their efforts to effectively exercise political control through surveillance and censorship. The end of sovereignty is a theme in political discussions about new pressures brought on by global regimes of trade and investment, and by unprecedented levels of global criminal networks for drug trafficking, money laundering and trade in human flesh. Social movements and non‐governmental organizations (NGOs) have reflected this by recognizing the need to match the scale of the problems they confront with appropriately scaled collective action. This article examines the discourse about the end of sovereignty and therise of new institutions of global governance. Particular emphasis is given to how advancements in the means of communication have produced the ambivalent outcomes of threatening the democratic governance of sovereign states, and serving as foundations for the assertion of democratic rights and popular sovereignty on a global scale.

In this chapter, we review the historical development of elite theory, and then we propose a way forward beyond it. Elite theory emerged as a critique of democracy in the late 19th century. Although it used historical materials illustratively, it tended to be ahistorical theoretically because its primary aim was to demonstrate the perdurance of elites even in conditions of mass suffrage. Lachmann was the first scholar to develop elite theory as a truly historical and explanatory framework by combining it with elements of Marxism. Even Lachmann's theory, however, remained inadequate because it did not rest on a fully articulated theory of power. In this introduction, we suggest a “relational power theory” as a remedy to this situation, and we use it to formulate a general heuristic for the study of elites, nonelites, and their interrelationships. To illustrate its utility, we show how it can illuminate the chapters in this volume (though they were not necessarily written for these purposes).
