The future of salmon aquaculture depends on the adoption of alternative feed resources in order to reduce the need for fish meal and fish oil. This may include resources such as species from lower trophic levels, by-products and by-catch from fisheries and aquaculture, animal by-products, plants, genetically modified (GM) plants, nutritionally enhanced GM plants and products from microorganisms and GM microorganisms. Here, we report on a deliberative assessment of these alternative feed resources, involving 18 participants from different interest groups within (...) Norwegian salmon aquaculture. The participants defined a broad range of appraisal criteria concerning health and welfare issues, economical issues, environmental issues, and knowledge and social issues. A number of uncertainties, in the form of incomplete knowledge, diverging opinions, and context specific factors were identified when the participants evaluated the alternatives. Our findings support the need for more research on the suitability of alternative feed resources for farmed salmon. Additionally, the study underlines the importance of facilitating deliberative assessments in order to map the plurality of perspectives and explore qualitative aspects of uncertainty. Such initiatives improve the information base upon which decisions on future feed resources for farmed salmon are made. (shrink)

The idea of the genetic unity of all mankind is an integral part of Christian teaching. The purpose of this brief survey is to illustrate its role within the Greek patristic tradition, and then to point to a few examples from modern science which lend support to this ancient idea.

As variants of the Christian tradition have emerged through the centuries they have given rise to distinct versions of Christian metaphysics with divergent cosmological commitments. In the early Church, the Cappodocian fathers constructed a theological framework which focuses on the “personal” nature of reality. The personal nature of reality is central not only to understanding key theological doctrines, such as the Trinity, but also the cosmos itself. This essay explores the Cappodocian conception of the cosmos as personal both in its (...) origin and as a medium for an interpersonal relationship between God and creatures. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:156 BOOK REVIEWS of theological method in Aquinas (p. 193; see also pp. 57 and 173). But this is not sufficient. Farthing should have acknowledged that Biel's recurrent critique of the supposed ' positive ' use of reason in Aquinas is beside the point and that, by thinking that Thomas is trying to ' demonstrate ' the faith, Biel has carelessly dismissed much that is interesting and valuable in (...) Aquinas. By bringing Biel's error to the fore, Farthing would have made clear to the reader that in this crucial respect, the dialogue between these two thinkers has completely broken down. University of Notre Dame Notre Dame, Indiana JOSEPH WAWRYKOW The Reshaping of Catholicism: Current Challenges in the Theology of Church. By AVERY DULLES. San Francisco: Harper & Row, 1988. Pp. 276. $19.95 (doth). Each of Dulles's twelve articles commends itself no less as a chapter in this collection than when it first appeared separately between 1984 and the end of 1987. In ensemble, " they give," Dulles remarks in his Preface, " a fair sampling of the issues the Catholic Church has had to face in the two decades since the Council." Whatever the leading Catholic ecclesiologist in America has to say about specific problems in Church renewal deserves careful attention. A positive general evaluation of the book is all hut a foregone conclusion. Still, a review can perform that opening survey of contents that will lend precision to a reader's anticipation of what the author has singled out as the current challenges. Four chapters take up the task of interpreting the texts of Vatican II, not as a species of source-criticism but in light of post-conciliar difficulties. Chapters 2 ("The Basic Teaching of Vatican II "), 5 ("Vatican II and the Recovery of Tradition"), and 8 ("Vatican II and the Purpose of the Church") emerge from a situation of divided opinion. They also apply the Council's teaching as a solution. Chapter 7 ("The Church and Communications") likewise engages conciliar texts, along a more speculative line. Chapter 1 ("American Impressions of the Council") joins with 2 in opening the book at a somewhat more popular level. The other chapters employ conciliar teaching to formulate theological answers to some important questions. These are questions which trouble not only the hierarchy and the theologians but also ordinary BOOK REVIEWS 157 members of the Church, as they come to terms with the Church's renewed self-understanding. Chapter 3 (" The Emerging World Church and the Pluralism of Cultures") picks up where Karl Rahner's wellknown address at the Weston School of Theology in 1979 left off. Dulles accepts Rahner's argument that Vatican II achieved the first official self-actualization of Catholicism as a world church. Taking the resulting problem of inculturation as the current phase in the relation between Christianity and culture, Dulles specifies the relation between two cultures as "cultural reciprocity." He leaves behind the simple, familiar contrast between classicism and a non-normative concept of culture. His ecumenical research enters into Chapter 4 ("The Meaning of Catholicism: Adventures of an Idea "), which places Vatican II in the context of two centuries of Protestant-Catholic discussion on the essence or basic idea of Catholicism. Intra-Catholic pluralism turning into opposition underlies most of the hook, hut Chapters 5 and 6 ("Authority and Conscience: Two Needed Voices") treat two such polarizations thematically. In 5 Dulles finds Dei Verbum open to an understanding of tradition as the handing on from generation to generation of the " tacit knowledge " whose content is the lived awareness of the God of Jesus Christ. Chapter 6 does not admit a second, alternative magisterium, hut it does situate hier· archical teaching amid the several sources of authority accepted by Catholicism-Scripture, tradition, the whole People of God, and theologians along with the hierarchy. And, in the formation of personal judgments and decisions, conscience has its own authority. A theology of communication follows from each of five models of the Church. Chapter 7 shows how this, in turn, implies a distinct approach to evangelization, use of mass media, and episcopal and papal teaching. Chapters 8 and 9 {"The Church, Society, and Politics") discuss the tensions inherent in the Church's mission... (shrink)

En stor del av dagens forskningsaktivitet er knyttet til utvikling av ny teknologi. Teknologiutvikling anses gjerne som et gode, fordi den bidrar til økt eller ny bruk av naturlige ressurser til beste for menneskers generelle levekår og helse, samt miljøet og samfunnet som helhet. Bruk av ny teknologi innebærer imidlertid også risiko for uønskede effekter. Risikovurderinger er ofte preget av vitenskapelig usikkerhet, spesielt med hensyn til effekter som oppstår over tid. Denne usikkerheten reiser nye etiske dilemmaer og gjør det nødvendig (...) med en kritisk vurdering av kunnskapsgrunnlaget. I denne artikkelen fokuserer vi på hvilke etiske utfordringer vitenskapelig usikkerhet har for forskning og forvaltning, og vi vil se nærmere på bruk av DNA-vaksiner i oppdrettsnæring. Vi argumenterer for at det er viktig å anerkjenne kvalitative former for vitenskapelig usikkerhet, som går utover det som uttrykkes i statistiske termer. Walker & Harremoeës usikkerhetsanalyse presenteres som en metode for å identifisere og systematisere vitenskapelig usikkerhet av kvalitativ karakter. En slik analyse kan øke forskeres evne til å reflektere over og kommunisere usikkerhet knyttet til eget arbeid. Vi argumenterer videre for at kommunikasjon av vitenskapelig usikkerhet bør være en del av forskerens etiske ansvar, blant annet for å stimulere føre-var-basert forskning og forvaltning. En helhetsvurdering av nytte, risikomomenter og usikkerhet kan best oppnås gjennom en tverrfaglig tilnærming. Det vil bidra til at de implisitte verdiene som er assosiert til bruk av ny teknologi blir bedre belyst. (shrink)
