Zusammenhänge zwischen spektralen Eigenschaften der Böden und ihren Gehalten an organischem Kohlenstoff (Corg) wurden mit vier Methoden untersucht. Messungen im Labor (Chromameter von Konica-Minolta, 400-700 nm) und im Feld (HandySpec Field, Tec5 AG, 360–1.000 nm) ergaben Korrelationen mit R = 0,63*** bzw. 0,52*** (n = 133). Aus Grauwerten eines hochaufgelösten Luftbildes wurde eine engere Korr...

A common objection to hierarchical approaches to truth is that they fragment the concept of truth. This paper defends hierarchical approaches in general against the objection of fragmentation. It argues that the fragmentation required is familiar and unproblematic, via a comparison with mathematical proof. Furthermore, it offers an explanation of the source and nature of the fragmentation of tr...

OBJECTIVE Theories of ethics and ethical reflection may be applied to both theory and practice in psychotherapy. There is a natural affinity between ethics and psychotherapy. Psychotherapy practice is concerned with human problems, dilemmas and emotions related to both one's own and other people's values. Ethics is also concerned with dilemmas in human thinking and with how these dilemmas refle...

• implementation techniques to assure such non-functional properties. In our opinion, there are at least three issues related to reflection: • what system aspects (such as structure or behaviour) are to be represented and operated upon, • how a system can reflect upon its own aspects, and • when a system reflects upon itself (e.g., design time, compile time, installation time, start-up time, or...

We study the relationship between the semistationary reflection principle and stationary reflection principles. We show that for all regular cardinals λ ≥ ω2 the semistationary reflection principle in the space [λ] implies that every stationary subset of E ω := {α ∈ λ | cf(α) = ω} reflects. We also show that for all cardinals λ ≥ ω3 the semistationary reflection principle in [λ] does not imply ...

(where an a f f i r m a t i v e sentential operator is informally characterized as one for which a p r i n c i p l e of d i s t r i b u t i o n over conjunction is not o b v i o u s l y implausible). Examples of such operators include the familiar modal operators ~ and 0, and also various epistemic and doxastic operators. I want to consider certain principles that may be held to govern certain ...

Background: Neuroimaging studies have demonstrated associations between delusions in psychotic disorders and abnormalities of brain areas involved in social cognition, including medial prefrontal cortex (MPFC), posterior cingulate cortex, and lateral temporal cortex (LTC)). General population studies have linked subclinical delusional thinking to impaired social cognition, raising the question ...

We define a reflection in a tree as an involutive automorphism whose set of fixed points is a geodesic and prove that, for the case of a homogeneous tree of degree 4k, the topological closure of the group generated by reflections has index 2 in the group of automorphisms of the tree.

We review the state-of-the-art of reflection and metaprogramming, prior to our work on partial behavioral reflection and Reflex, and open implementations. The first four sections are dedicated to reflection. Section 1 introduces the concept of reflection and its application to programming languages. Section 2 discusses reflection in the particular context of object-oriented programming language...

We prove general reflection positivity results for both scalar fields and Dirac fields on a Riemannian manifold, and comment on applications to quantum field theory. As another application, we prove the inequality CD ≤ CN between Dirichlet and Neumann covariance operators on a manifold with a reflection.
