In a very general sense, hybrid can be understood to be any organism that is the product of two (or more) organisms where each parent belongs to a different kind. For example; the offspring from two or more parent organisms, each belonging to a separate species (or genera), is called a “hybrid”. “Hybridity” refers to the phenomenal character of being a hybrid. And “hybridization ” refers to both natural and artificial processes of generating hybrids. These processes include mechanisms of selective (...) cross-breeding and cross-fertilization of parents of different species for the purpose of producing hybrid offspring. In addition to these processes, “hybridization ” also refers to natural and artificial processes of whole genome duplication that result in the doubling or trebling of the sets of chromosomes of the organism. This entry provides an overview of the impact of hybridity on agriculture. It begins with an historical sketch that traces the early horticulturalists’ and naturalists’ investigations of hybrids. This starts with the observations of Thomas Fairchild and Georges-Louis Leclerc, Comte de Buffon; and leads to the explanation of its mechanism by Gregor Mendel, James Watson and Francis Crick, and Ernst Mayr; and the eventual manipulation of hybrids and hybridization by Barbara McClintock. Following this, the reader is introduced to a number of key terms and concepts in use within current research as well as highlighting diverse ethical concerns that center on hybridization. Recent research that attempts to ascertain the role of hybridization in adaptive change will be introduced. This will include research on the evolution of crop species, increased biodiversity, and the use of hybrids to manipulate phenotypically desirable traits in agricultural crops. The focus of the discussion is on a particularly significant type of naturally occurring hybridization, polyploidy hybridization. Polyploids are organisms which have more than two complete genomes in each cell. This kind of hybridization is ubiquitous among crop plants. The role of polyploidy in plant evolution and the affects of polyploidy on plants and animals will be reviewed. A critical discussion of its agricultural value in the production of fertile polyploid hybrids highlights key epistemological, ontological, and ethical issues. These are illuminated with reference to the distinct processes of artificial and natural hybridization. A survey of these different kinds of hybridization includes the ethical and economic impacts of hybridity on global nutrition, the environment, and considerations of some practical implications for the agricultural industry. Tracking the role of hybrids, the process of hybridization, and the current impacts of it for agriculture requires knowledge of the history of its early conceptualization, understanding, and use. This is the topic of the following section. (shrink)

Understanding stakeholders’ perceptions and motivations is of significant importance in relation to conservation and protected area projects. The importance of stakeholder analysis is widely recognized as a necessary means for gaining insight into the complex systemic interactions between natural processes, management policies, and local people depending on the resource. Today, community and group-based participatory inquiry approaches are widely used for this purpose. Recently, participatory approaches have been critiqued for not considering power relations and conflict internal to the community. In this (...) article, we suggest that the five-step Rapid Stakeholder and Conflict Assessment (RSCA) methodology addresses this critique. The objective of the methodology is to provide a facilitator with a comprehensive foundation on which to plan and conduct subsequent participatory project development. The RSCA integrates elements of soft systems and critical systems thinking. Qualitative research interviews and cognitive mapping of stakeholders’ mental models are used for collection of empirical material and analysis. The RSCA methodology is demonstrated in a case study concerning buffer zone management in the coastal wetlands of southern Vietnam. The case study shows that the RSCA methodology can provide an efficient way of obtaining a holistic and critical understanding of a complex resource management situation, thus potentially enhancing project performance in an instrumental as well as an ethical sense.

Hospital waiting lists are a feature ofpublicly funded health services that resultswhen demand appears to exceed supply. Whilemuch has been written about hospital waitinglists, little is known about the dynamics ofdiagnostic waiting lists, or more generally whyhospital waiting lists behave in perverse andoften counter-intuitive ways. This paperattempts to address this gap by applying arecent development in critical systems thinkingcalled boundary critique to understand how aparticular ultrasound waiting list was managed.A new waiting list metaphor based on waitinglists as ritual forms is (...) proposed.

Judgements concerning proper or appropriate educational endeavour, methods of investigation and philosophising about education necessarily implicate perspectives, values, assumptions and beliefs. In recent years ideas from the complexity sciences have been utilised in many domains including psychology, economics, architecture, social science and education. This paper addresses questions concerning the appropriateness of utilising complexity science in educational research as well as issues relating to the ways in which complexity might be engaged. I suggest that, just like all human endeavour, approaches to (...) research emerge out of discursive communities and can be understood as self‐organising, dynamic and emergent over time. In this formulation, complexity represents one such newly emergent approach. I argue that it is important that researchers partake in critical and reflective discourse about the nature of education and conceptual frameworks, as well as about impacts and legacies of utilising complexity, so as to participate in and influence the ongoing emergence of educational endeavour. I conclude by suggesting a series of caveats for researchers considering using complexity in educational research. (shrink)

This theoretical paper takes an agency-theoretic approach to questions of corporate social responsibility (CSR). A comparison of various extant frameworks focusses on how CSR agency emerges in complex multi-agent and multi-sector stakeholder networks. The discussion considers the respective capabilities and relevance of these frameworks – culminating in an integrative CSR practice model. A short literature review of the evolution of CSR since the 1950’s provides the backdrop for understanding multi-agent cross-sectoral stakeholder coalitions as a strategic determinant of today’s organizational behavior. (...) The paper turns to Werhane’s coupling of moral imagination and systems thinking and forging stakeholder coalitions in problem contexts that were traditionally deemed intractable by for-profit organizations. However, it identifies the problem that the systems approach treats macro-agents (organizations, stakeholders) as given (“black-boxed”) and shies away from more radically re-imagining the possibilities of reassembling agency from the bottom up. Actor Network Theory (ANT) provides such a method, which strictly commits to treating organizational behavior as a product of technological, human and environmental micro-processes. ANT, however, is lacking a genuine moral deliberative stance in designing complex CSR coalitions. In an attempt to capitalize on the respective strengths of these frameworks (Systems thinking and ANT) the paper tends to a recent iterative series of “situational transactive” models that are rooted in the US pragmatist tradition and seek to capture intelligent planning processes in complex problematic contexts. The contribution proposes a new CSR practice model, which assigns specific roles to the theoretical contributions of ANT, system thinking and pragmatism in complex deliberation processes. This model can be industry-tested in a future study. (shrink)

Review of "The Timeless Way of Building." Book by Christopher Alexander.

The current dominant approach on the assessment of critical thinking takes as a starting point a conception of criticality that does not commit to any substantive view or context of meaning concerning what issues are relevant to be critical about in society or in life. Nevertheless, as a detailed examination of the identification of assumptions shows, when going from the theory of critical thinking to the praxis of producing and evaluating arguments, the critical person will inevitably make such commitments from (...) particular perspectives, using particular contexts of meaning. But then she may fail to take notice of relevant ones and may end up using her critical powers in a mercenary way. It is then proposed, in the context of assessment of critical thinking, to choose and use some privileged contexts of meaning, while making them available for critical scrutiny and allowing for the possibility that new ones be brought up by those being assessed.

The recent drastic development of agriculture, together with the growing societal interest in agricultural practices and their consequences, pose a challenge to agricultural science. There is a need for rethinking the general methodology of agricultural research. This paper takes some steps towards developing a systemic research methodology that can meet this challenge – a general self-reflexive methodology that forms a basis for doing holistic or (with a better term) wholeness-oriented research and provides appropriate criteria of scientific quality.From a philosophy of (...) research perspective,science is seen as an interactive learning process with both a cognitive and a social communicative aspect. This means, first of all,that science plays a role in the world that it studies. A science that influences its own subject area, such as agricultural science, is named a systemic science. From this perspective, there is a need to reconsider the role of values in science. Science is not objective in the sense of being value-free.Values play, and ought to play, an important role in science – not only in form of constitutive values such as the norms of good science, but also in the form of contextual values that enter into the very process of science. This goes against the traditional criterion of objectivity. Therefore, reflexive objectivity is suggested as a new criterion for doing good science, along with the criterion of relevance. Reflexive objectivity implies that the communication of science must include the cognitive context, which comprises the societal,intentional, and observational context. Ina ccordance with this, the learning process of systemic research is shown as a self-reflexive cycle that incorporates both an involved actor stance and a detached observer stance. The observer stance forms the basis for scientific communication.To this point, a unitary view of science as a learning process is employed. A second important perspective for a systemic research methodology is the relation between the actual,different, and often quite separate kinds of science. Cross-disciplinary research is hampered by the idea that reductive science is more objective, and hence more scientific, than the less reductive sciences of complex subject areas – and by the opposite idea that reductive science is necessarily reductionistic. Taking reflexive objectivity as a demarcator of good science, an inclusive framework of science can be established. The framework does not take the established division between natural, social, and human science as a primary distinction of science.The major distinction is made between the empirical and normative aspects of science,corresponding to two key cognitive interests.Two general methodological dimensions, the degree of reduction of the research world and the degree of involvement in the research world, are shown to span this framework. The framework can form a basis for transdisciplinary work by way of showing the relation between more and less reductive kinds of science and between more detached and more involved kinds of science and exposing the abilities and limitations attendant on these methodological differences.

We all know that ships are safest in the harbor; but alas, that is not what ships are built for. They are destined to leave the harbor and to confront the challenges that are waiting beyond the harbor mole. A similar challenge confronts the practice of research. Research at work cannot play it safe and stay in whatever theoretical and methodological harbors in which it may have found shelter in the past. Still less can it examine and maintain its foundations (...) in the dry dock. Research is more like a ship that must be repaired on the open sea. Yet foundationalist ideas persist in the practice of research. Counter to what is often assumed, today’s dominating model for research--the fallibilist model of critical rationalism--has not really overcome the empirical foundationalism of earlier, positivist research practices. This paper analyses two major foundationalist traps that are currently in the upswing and work against reflective research practice. (shrink)

There is continuing interest in action research in health care. This is despite action researchers facing major problems getting support for their projects from mainstream sources of R&D funds partly because its validity is disputed and partly because it is difficult to predict or evaluate and is therefore seen as risky. In contrast traditional health science dominates and relies on compliance with strictly defined scientific method and rules of accountability. Critics of scientific health care have highlighted many problems including a (...) perpetual quality gap between what is publicly expected and what is deliverable in the face of rising costs and the cultural variability of scientific medicine. Political demand to close the quality gap led to what can be seen as an elitist reform of policy on UK health research by concentrating more resources on better fewer centres and this may also have reduced support for action research. However, incompetent, unethical or criminal clinical practice in the UK has shifted policy towards greater patient and public involvement in health care and research. This highlights complementarity between health science and action research because action research can, as UK health policy requires, involve patients and public in priority setting, defining research outcomes, selecting research methodology, patient recruitment, and interpretation of findings and dissemination of results. However action research will remain marginalised unless either scientific research is transformed generally into a more reflective cycle or there is increased representation of action research enthusiasts within the establishment of health R&D or current peer review and public accountability arrangements are modified. None of these seem likely at this time. The case for complementarity is illustrated with two case studies. (shrink)
