Klein, Renate The practice of surrogacy in Australia has been controversial since its beginning in the late 1980s. In 1988, the famous 'Kirkman case' in the state of Victoria put surrogacy on the national map. This was a two-sisters surrogacy - Linda and Maggie Kirkman and the resulting baby Alice - in which power differences between the two women were extraordinarily stark: Maggie was the glamorous and well spoken woman of the world; Linda who carried the baby, was the (...) demure school teacher in child-like frocks and pig tails. Their IVF doctor applauded altruistic surrogacy. He called it 'gestational surrogacy' and proclaimed that if the so-called surrogate mother didn't use her own eggs, thus wasn't the baby's 'genetic' mother, no attachment would ensue! This statement is haunting us to this day. It is patently absurd: as a baby grows in a woman's body over the nine months of the pregnancy, it is hard to see why the 24/7 presence of the baby inside her body, its growth, its interaction with her (movements, the baby's kicking) would be any different whether s/he has the mother's genes!

In this paper I shall compare two models of concept formation, both inspired by basic convictions of philosophical empiricism. The first, the connectionist model, will be exemplified by Kohonen maps, and the second will be my own dynamic theory of concept formation. Both can be understood in probabilistic terms, both use a notion of convergence or stabilization in modelling how concepts are built up. Both admit destabilization of concepts and conceptual change. Both do not use a notion of representation in (...) some pregiven language, such as a language of thought or some logical language. Representation in a formal language only plays a role on the meta-level, namely within the theory about concept formation. (shrink)
mechanism" is frequently encountered in the social science literature, but there is considerable confusion about the exact meaning of the term. The article begins by addressing the main conceptual issues. Use of this term is the hallmark of an approach that is critical of the explanatory deficits of correlational analysis and of the covering-law model, advocating instead the causal reconstruction of the processes that account for given macro-phenomena. The term "social mechanisms" should be used to refer to recurrent processes generating (...) a specific kind of outcome. Explanation of social macro-phenomena by mechanisms typically involves causal regression to lower-level elements, as stipulated by methodological individualism. While there exist a good many mechanism models to explain emergent effects of collective behavior, we lack a similarly systematic treatment of generative mechanisms in which institutions and specific kinds of structural configurations play the decisive role. Key Words: causal regression • correlational analysis • emergent effects • micro-macro processes • social mechanisms • structural determinants. (shrink)
A key challenge faced by organizations is to provide project teams with workspaces, information, and collaboration technologies that fosters creativity and high-performance team productivity. This requires understanding the relation between and impacts of (1) workspace, (2) activity and content that is created, and (3) social, behavioral, and cognitive aspects of work. This paper describes an exploratory study of everyday activities in the context of knowledge work in a shared workspace used by a high-tech global design team that explores future products. (...) The study formalizes key elements for productive knowledge work as a function of tasks, context, and team. It identifies enablers, hindrances, and requirements for physical, virtual, and social work environments. The study identified, through semi-structured interviews, surveys, and on-site shadowing, a key workspace component that facilitates dynamic participation of all team members. This workspace component is a wall used as a large, public, physical display surface for project content (the WALL). The WALL acts as a mediator for individual reflection-in-action and team reflection-in-interaction. It serves as “social glue” both between individuals and between geographically distributed subgroups. (shrink)

We explore in this paper the relation between activities, communication channels and media, and common ground building in global teams. We define re-representation as a sequence of representations of the same concept using different communication channels and media. We identified the re - representation technique to build common ground that is used by team members during multimodal and multimedia communicative events in cross-disciplinary, geographically distributed settings. Our hypotheses are as follows: (1) Significant sources of information behind decisions and request for (...) actions are embedded within the fabric of communicative events in which participants use both informal and formal media to express their ideas. Capturing these information sources can facilitate common ground building and accelerate the execution of action requests. (2) Re-representations of concepts, i.e., sequences of representations using diverse media and communication channels, mediate and accelerate common ground building. (3) The use of intra- or interdisciplinary re-representations correlates with high team performance, i.e., effective team process and high product quality. We used AEC Global Teamwork course offered in 2008–2009 as the testbed for our study to validate our hypothesis. (shrink)
Using a generalized conception of experience, from which all features characteristic for higher animals (such as consciousness and thought) have been removed, allowed relating experience to adaptive processes in lower organisms. The temporal vector character of every current experience, containing as well memories of past experiences as intentions for future activities, can then be found in the adaptive response of cyanobacteria to alterations in phosphate supply, particularly in energetic manifestations of this phenomenon. A possible analogy between adaptive events as the (...) “atomic units” of physiological adaptation and Whitehead's actual occasion of experience is discussed. (shrink)
We prove completeness and decidability results for a family of combinations of propositional dynamic logic and unimodal doxastic logics in which the modalities may interact. The kind of interactions we consider include three forms of commuting axioms, namely, axioms similar to the axiom of perfect recall and the axiom of no learning from temporal logic, and a Church–Rosser axiom. We investigate the influence of the substitution rule on the properties of these logics and propose a new semantics for the test (...) operator to avoid unwanted side effects caused by the interaction of the classic test operator with the extra interaction axioms.

This paper discusses ethics in the context of Aboriginal Studies. Taking the example of a late-nineteenth century missionary work, a collection of out-of-print Mi’kmaq stories, it examines the ethical implications of the potential re-publication of such a text. It is argued that the Baptist missionary Silas T. Rand, who translated and transcribed the narratives, did his work from a Eurocentric perspective. The biases of a colonial ideology built into his translations/interpretations which are often quoted as authoritative would be further perpetuated (...) if his work is republished without critical commentary. As Aboriginal oral traditions generally form the basis of Aboriginal cultures and contemporary Aboriginal literatures but have been demeaned for centuries thereby further colonizing the peoples, an edition of Rand’s work informed by a postcolonial ethics is crucial. The paper therefore concludes with the suggestion that the stories collected by the missionary should be repatriated in the respective Mi’kmaq communities in a way that the people can decide how to go about their publication (if they want them published at all). A non-Aboriginal scholar may facilitate the process but should follow the directions of the communities. (shrink)
The properties of the phosphate uptake system of the cyanobacterium Anacystis nidulans have been studied during the transition from a phosphate-deficient non-growing state to a non-deficient growing state. In the phosphate-deficient state the high affinity phosphate transport system in the cell membrane is extremely adaptive. As a result of these adaptive features the phosphate transport system cannot be described by determinate, fixed parameters, because the transport system is influenced by the measurement of the uptake process itself. When the growing state (...) has been initiated by a persisting phosphate pulse, the transport system rapidly loses its adaptive features and can then be characterized by determinate parameters that remain unchanged for a long period of time, even if no uptake occurs in that time. Depending on the amount of phosphate stored during a pulse the cell makes a choice between slow or fast growth. In the latter case the light harvesting and energy converting machinery is completely reorganized before growth commences. Thereby the components of this machinery conform to each other and to the stable properties of the phosphate transport system. It is suggested that the mutual adjustment of these adaptive energy converting subunits is guided by attractors that function as the final cause for the development of the whole system.An application of this model to an analysis of the selforganization of aquatic ecosystems is discussed.

This paper considers a new class of agent dynamic logics which provide a formal means of specifying and reasoning about the agents activities and informational, motivational and practical aspects of the behaviour of the agents. We present a Hilbert-style deductive system for a basic agent dynamic logic and consider a number of extensions of this logic with axiom schemata formalising interactions between knowledge and commitment (expressing an agent s awareness of her commitments), and interactions between knowledge and actions (expressing no (...) learning and persistence of knowledge after actions). The deductive systems are proved sound and complete with respect to a Kripke-style semantics. Each of the considered logics is shown to have the small model property and therefore decidable. (shrink)
The author's experiences in an ethics seminar for business school faculty are described. Conclusions from the dynamics of the participants' interactions are drawn and recommendations are made for teaching business school students about ethics.
Patients' wishes regarding health care and dying must be taken into consideration by their physicians. Competent patients need to record directives about their care in advance of a crisis situation. The primary care physician, seeing the patient at the time of a routine office visit, is in a favorable position to explore and record attitudes. A patient's value system should be part of a medical history before hospital admission. Details in a Value History Questionnaire facilitate guiding an incompetent patient through (...) a terminal illness in accordance with wishes previously expressed.An instrument in the form of a questionnaire was designed to record the attitudes of 200 patients regarding health care and dying. Respondents ranged in age from 17 to 84 years, and all were members of one family practice. They reacted positively to the opportunity to record their values, opinions, and wishes about their health care and process of dying. They clearly indicated that, in the absence of prior directives, they would want their families consulted about crucial decisions. (shrink)
The organization, processing and representation of knowledge becomes increasingly important in all scientific and business contexts. This book focuses on qualitative methods for knowledge organization and their contributions to knowledge-based issues of marketing management research. Besides theoretical discussions of different approaches to and definitions of knowledge, as well as methods for knowledge organization, several case studies in the field of marketing management are presented. Questions of research design, adequate choice of methodologies and practical relevance of the results are addressed.
Contemporary cost containment measures ignore patients' need for privacy, destroy long-term doctor-patient relationships, and demand ethical and standard of care compromises.Economic considerations have distracted the physician and he/she no longer focuses primarily on the patient's welfare. The superficiality of the doctor-patient relationship and the cost-cutting efforts have jointly contributed to the deterioration of the quality of medical care.
This paper presents a new perspective of the impact of collaboration technology on the degrees of engagement and specific interaction zones in interactive workspaces. The study is at the intersection of the design of physical work spaces, i.e., bricks, rich electronic content such as video, audio, sketching, CAD, i.e., bits, and new ways people behave in communicative events, i.e., interaction. The study presents: (1) an innovative multi-modal collaboration technology, called RECALL (patented by Stanford University), that supports the seamless, real-time capture (...) of concept generation during project brainstorming and project review sessions, (2) the deployment of RECALL in an interactive workspace that supports real project review sessions, called FISHBOWL, and (3) the observations of the impact of RECALL and the interactive workspace on degrees of engagement and interaction zones as it is deployed in the specific FISHBOWL sessions.

INTERNATIONAL STUDIES IN THE PHILOSOPHY OF SCIENCE Vol. 5, number 1, Autumn 1991, pp. 79-87. R.M. Nugayev. -/- The fundamental laws of physics can tell the truth. -/- Abstract. Nancy Cartwright’s arguments in favour of phenomenological laws and against fundamental ones are discussed. Her criticisms of the standard cjvering-law account are extended using Vyacheslav Stepin’s analysis of the structure of fundamental theories. It is argued that Cartwright’s thesis 9that the laws of physics lie) is too radical to accept. A model (...) of theory change is proposed which demonstrates how the fundamental laws of physics can, in fact, be confronted with experience. -/- . (shrink)
When Renat and I were preparing for this session we noticed the following irony: Although each of us is dubious about the fruitfulness of trying to explain the development of science in terms of the local sociopolitical scene, we each agreed that when it comes to understanding the development of philosophy of science in the last few decades, then the sorts of factors focused on by “new age” approaches to science studies actually play a major role!
The epistemological problems of unification of two distinct theories are discussed. An approach related to the work of Soviet authors (Stepin, Podgoretzky and Smorodinsky) is used and developed. The notion of ‘crossbred objects’—theoretical objects with contradictory properties which are part of the domain of application of two independent theories—is introduced which helps to describe the dynamics of revolutionary theory change. The occurrence of the cross-contradiction of two theories is reconstructed and the reductionistic and the synthetic means of its elimination are (...) proposed. The results of the methodological analysis are applied to the paradox of equivalence. (shrink)
