Janzen-Connell patterns are not the result of Janzen-Connell process: Oak recruitment in temperate forests
International audienceAccording to the Janzen-Connell hypothesis, seedling mortality is greater close to conspecific (or closely related) adult trees because of higher enemy pressure, ultimately increasing local tree-species diversity. However, this pattern (i.e. a decline of seedling performance close to conspecific or closely related adults) could also result from other processes: (1) heterospecific adults might positively affect seedlings; (2) conspecific (or closely related) adults might negatively affect seedlings by causing a deterioration of the microenvironment. We tested these hypotheses, accounting also for sizes of adults. We planted oak-seedlings in a temperate forest, characterized their adult neighbourhoods, measured 26 microenvironmental conditions, seedling mortality during one year, budburst and leaf herbivory. We detected Janzen-Connell-like patterns (frequent lack of budburst close to conspecific adults; high seedling mortality close to closely related adults) that were consistent with the Janzen-Connell process. However, these patterns were either counteracted by non-Janzen-Connell processes such as a favourable microenvironment or were weak with little explained variance. We detected Janzen-Connell-like patterns that were not consistent with the Janzen-Connell process: proximity to heterospecific adults per se decreased leaf herbivory partly due to microenvironmental effects, such that a lower leaf herbivory decreased seedling mortality. Overall, the spatial pattern of tree recruitment may resemble that predicted by Janzen-Connell but result from different processes: notably heterospecific adults creating refuges from enemies, facilitating the establishment of oaks below non-oaks without hindering their establishment below oaks

Evaluating healthcare information systems through an "enterprise" perspective
Here we reflect upon the design and implementation of large-scale healthcare IS, noting the tendency of such systems to gravitate from a delivery (clinical) to a control (managerial) emphasis. Drawing on the concept of the 'enterprise model', we examined how adopting different perspectives of the enterprise might inform both design and evaluative criteria. Three areas of tension were identified; these prompted us to consider some elements that contribute to a framework that can guide the implementation and evaluation of healthcare applications. We proposed an illustrative conceptual model which, while not claiming to identify causal factors for success or failure, nevertheless gives indications of the interplay between the areas of tension. <br/

A counterexample to a conjecture of Bass, Connell and Wright
Let F=X-H: → be a polynomial map with H homogeneous of degree 3 and nilpotent Jacobian matrix J(H). Let G=(G_1,...,G_n) be the formal inverse of F. Bass, Connell and Wright proved in [1] that the homogeneous component of of degree 2d+1 can be expressed as , where T varies over rooted trees with d vertices, α(T)=CardAut(T) and is a polynomial defined by (1) below. The Jacobian Conjecture states that, in our situation, is an automorphism or, equivalently, is zero for sufficiently large d. Bass, Connell and Wright conjecture that not only but also the polynomials are zero for large d. The aim of the paper is to show that for the polynomial automorphism (4) and rooted trees (3), the polynomial is non-zero for any index (Proposition 4), yielding a counterexample to the above conjecture (see Theorem 5)
