Abstract During long-term research (almost forty years) of tailings containment in Chvaletice (Eastern Bohemia) were also carried out studies on the role of each plant dominants in succession. This review presents the most interesting results of these studies.

This report from the field describes some of the author’s methods of audience engagement as a means of social engagement, discussing the implications for practice. The report invites dialogue with the reader about the usefulness of audience engagement and ways it can be manifested before, during and after performance. Theatre is a vibrant and valuable tool for sparking dialogue and inspiring action around challenging social topics. Audiences who are engaged in the process of the performance beyond the standard role of passive spectator are more likely to be motivated to deliverable endeavors post performance. This report from the field offers four brief case studies as examples of audience engagement and includes pragmatic techniques for using theatre as a vehicle for personal and social change through audience engagement. It explores how artists can galvanize and empower audiences by creating experiential communities pre, during, and post-show. Drawing upon examples from high-quality international theatre projects written and directed by the author, the essay investigates and describes the work of The H.E.A.T. Collective including My Heart is in the East (U.S., U.K. and Europe), The FEAR Project (produced in the US, India and Czech Republic), Emma Goldman Day (U.S.).

Complexity is both a buzzword and a paradigm in the biophysical sciences and, increasingly, the social sciences. We define “social complexity” as the nonlinear escalation of costs and emergent infrastructure with rising energy use and concentrated power as societies develop. Two paths to social complexity are technotasking, which relies on technological break-throughs and is often politically hierarchical, and labortasking, which relies on skilled labor pools and is often heterarchical. We suggest several pathways to greater degrees of complexity and present two case studies emphasizing the role of labor-tasking; an in-depth review of the ancient Maya and a shorter introduction to the recent Balinese. Both of these complex societies used labortasking to adapt to local ecological limitations in semitropical settings. These societies used heterarchical organizations to accretionally engineer and manage their environments, strategies that promoted long-term resilience. Case studies such as these provide a nuanced picture of different paths to social complexity and highlight their relative costs, benefits, and potential for long-term sustainability.

ABSTRACTThis paper revises current understandings of the rôle of land in the economy of the Italian diaspora in the Greek East in the second and first centuriesb.c., arguing that these Italians owned more land than has previously been assumed and that many of these Italian landowners practised a highly commercialized form of agriculture that focused on high-end products. This strategy shaped what empire meant both locally and in Italy and Rome, where the products they marketed fed into the ongoing consumer revolutions of the time. After discussing the evidence for the extent of Italian landholdings and examining their exploitation in three case studies, we conclude by reflecting on the long-term history of such landholdings in the provinces and the implications for our understanding of Roman imperialism more generally.

ABSTRACTThe paper discusses the role of actuaries within the NHS. Actuaries have applied the concept of Geographic Information Systems to health data on patient traffic flows, transportation studies and specialty specific information on NHS providers (such as hospitals, ambulance stations and GP practices). Actuaries have been working with NHS Trusts to generate private patient income. Actuarial modelling developments, as part of a multi-disciplinary approach, have been used to interpret health data and to assist with the reconfiguration of NHS services. Actuaries have also been involved in long-term health services planning and in the financial planning of services for chronically ill patients.The paper outlines a series of case studies involving actuaries working in the NHS, highlighting their unique contributions. The case studies include advising on emergency health services planning, acute hospital service planning, NHS Trust private patient unit income generation, comparative peer group ranking studies, long-term population projections, health needs assessment and a feasibility study for a provider unit to care for the chronically ill. Finally, we discuss the role of the actuary in the NHS and his or her ability to build a communication bridge between NHS purchasers and providers, in the public interest.

This paper examines the internationalization process in three knowledge-based ventures in the biotechnology and IT sectors in the Czech Republic and Hungary. The findings from the case studies illustrate the motivations and outcomes of internationalization, along with some of the challenges faced by knowledge-based ventures when embarking on an internationalization strategy within the specific environment of a post-transition economy. Furthermore, the importance of relationships in both the internationalization process and the entrepreneurial process in general is discussed.

AbstractThe exceptional vulnerability of the fish species orange roughy has been amply demonstrated by the collapse of various relatively new fisheries where management and conservation measures were absent, inadequate or simply too late. Each of the three case studies of orange roughy fisheries discussed in this article has an inherent international dimension as they concern discrete high seas stocks, straddling stocks or stocks on whose categorisation states disagree. The case studies illustrate the more general shortcomings of the international legal framework for the management and conservation of marine living resources, but also specifically for vulnerable species like orange roughy. Crucial to long-term sustainable management are the issues of participation in regional fisheries management mechanisms or negotiation processes to establish them, as well as the allocation of fishing opportunities thereunder. Possibly, the role of marine scientific research can be further enhanced in relation to the categorisation of stocks and the concept of zonal attachment.

AbstractThis paper examines the conditions under which annual hours (AH) are likely to succeed or fail and the role of workplace partnership in delivering mutual gains. We explore two case studies, in one company with a positive experience and in a second where AH were regarded as a failed initiative. The case studies are constructed from interviews with trade union and management representatives in the companies involved; from secondary sources and from a worker survey. The findings echo previous research that AH can deliver mutual gains in both the presence and absence of workplace partnership (Author and Author, 2016) and that delivery of real mutual gains is the key driver of the long term viability of AH. However, the balance of mutual gains is subject to change and is strongly influenced by structural factors determining the suitability of AH to the particular enterprise.
