Naming the Beast: Defining and Classifying Service Innovations in Social Policy

Over the last decade, the search for innovationhas become a core component of much social policyformulation and implementation. This search, however,has often been undertaken with little attempt to define the actual nature of innovation or to classifyits different modes. This paper reports recent researchwhich has developed a typologyof organizational changewithin which to situate and analyze innovation in social policy. It argues that thistypologyis an essential tool both for socialpolicymakers and for those concerned with itsanalysis.     

Hook‐Ups and Train Wrecks: Contextual Parameters and the Coordination of Jazz Interactions

This article discusses the importance of several parameters of context integral to jazz musicians' ability to hear musical signs as meaningful, such as performers' individual backgrounds and the various other styles of music available in the aural landscape, and how those parameters influence what the musicians play. Several examples from an ongoing ethnography of jazz jam sessions suggest that context is constituted by several variables, that different variables may become salient at different times, and that different interactants vary in their ability to attend to these variables. This study thus extends and elaborates frame analysis by showing that, while an interaction frame of the sort described by Goffman (1974) may perdure, it is subject to change, and the nature of the context it provides for interactions can change whenever a new interaction is initiated.     

On the trimmed mean and minimax-variance L-estimation in Kolmogorov neighbourhoods

We consider the properties of the trimmed mean, as regards minimax-variance L-estimation of a location parameter in a Kolmogorov neighbourhood K() of the normal distribution: We first review some results on the search for an L-minimax estimator in this neighbourhood, i.e. a linear combination of order statistics whose maximum variance in K_t() is a minimum in the class of L-estimators. The natural candidate – the L-estimate which is efficient for that member of K_t,() with minimum Fisher information – is known not to be a saddlepoint solution to the minimax problem. We show here that it is not a solution at all. We do this by showing that a smaller maximum variance is attained by an appropriately trimmed mean. We argue that this trimmed mean, as well as being computationally simple – much simpler than the efficient L-estimate referred to above, and simpler than the minimax M- and R-estimators – is at least “nearly” minimax.     

Identity Agents: Parents as Active and Reflective Participants in Their Children's Identity Formation

The paper introduces the concept of identity agents. This concept refers to those individuals who actively interact with children and youth with the intention of participating in their identity formation, and who reflectively mediate larger social influences on identity formation. This contrasts with the focus of mainstream research in the identity field that tends to portray adolescents as the sole reflective agents involved in mature identity development. The paper presents a theoretical analysis presenting the importance of the concept for the formulation of a comprehensive contextual theory of identity formation. The particulars of this concept are illustrated through the presentation of a qualitative report of religious parents actively encouraging their children's processes of identification, co‐participating in their children's identity's formation, and reflectively deliberating their parental roles and goals in regards to this process.     

E-optimal designs for three treatments

E-optimality is studied for three treatments in an arbitrary n-way heterogeneity setting. In some cases maximal trace designs cannot be E-optimal. When there is more than one E-optimal design for a given setting, the best with respect to all reasonable criteria is determined.     

Auftragsklärung: Interventionen auf dem Wege zur Konstituierung eines Beratungssystems*

The author demonstrates basing on a case study, that the development of a consultation system is a process that requires time and patience of everyone involved. Not a fast decided definition of a consultation method with the corresponding setting is the first step but a clarification of the request. That is what the author is pleading for a phase of detailed analysis with the potential client.     

On Bayesian D-optimum Design Criteria and the Equivalence Theorem in Non-linear Models

The concavity of some Bayesian D -optimality criteria is investigated and is found in some cases to depend on the prior distribution. In the case of a non-concave criterion, the standard equivalence theorem may fail, but a local version continues to apply.     

Using scenarios to develop strategies

Scenarios were not used for strategic decision-making until some time after their introduction. Structured approaches which fully use scenarios for strategy development have only emerged in the last few years. This paper describes such an approach as practised in Shell Nederland and focuses on the business environment with reference to the norms and values. A second paper dealing with the values in more details will appear in the next issue.
