Public procurement is seen as a powerful instrument for innovation policy, but meaningful barriers seem to hinder its deployment. This study reviews literature on complexity, time consumption, and risk representing important hindrances for the procurement of innovation from public buyers' perspective. Findings provide evidence on the existence of hindrances for public procurement of innovation across European Union member states through the analysis of data from a large-scale survey. Further, differences in terms of the perception of barriers become evident depending on the availability of monitoring systems for innovation performance. 相似文献

We present a comprehensive framework for Bayesian estimation of structural nonlinear dynamic economic models on sparse grids to overcome the curse of dimensionality for approximations. We apply sparse grids to a global polynomial approximation of the model solution, to the quadrature of integrals arising as rational expectations, and to three new nonlinear state space filters which speed up the sequential importance resampling particle filter. The posterior of the structural parameters is estimated by a new Metropolis–Hastings algorithm with mixing parallel sequences. The parallel extension improves the global maximization property of the algorithm, simplifies the parameterization for an appropriate acceptance ratio, and allows a simple implementation of the estimation on parallel computers. Finally, we provide all algorithms in the open source software JBendge for the solution and estimation of a general class of models. 相似文献

It is shown that permutation tests have optimum properties for interesting classes of continuous distributions as well as
for discrete ones. General conditions sufficient for uniformly maximal power on subclasses are given. Moreover, a variety
of examples is presented.

The philosophy of coaching. Anthropological, hermeneutical and ethical implicationsCounselling and coaching can be understood as modern means to foster human autonomy, following the normative idea of the enlightenment. This anthropology must be completed with the Heideggerian concept of care, which clears misunderstandings of an asymmetry between coach and client. The hermeneutical dimension of coaching is analysed as creative and perspectival understanding on the basis of a fundamental questionability. With this innovative philosophical interpretation of coaching, its ethical values are adequately grounded. 相似文献

Summary:
Based on a nonparametrically estimated model of labor market classifications, this paper makes suggestions for immigration policy using data from West Germany of the 1990s. It is demonstrated that nonparametric regression is feasible in higher dimensions with only a few thousand observations. In sum, labor markets are able to absorb immigrants are characterized by above average age and by professional occupations. On the other hand, labor markets for young workers in service occupations exhibit rising unemployment due to wage rigidities and are therefore not recommended for immigration. This raises a potential conflict between financing Germanys ailing social security system and protecting decreasing or rigid labor markets by immigration control.*We are grateful to Daron Acemoglu, Joshua Angrist, Herbert S.

Coaching — orientation on performance and expectations of managersThe author discusses the up to now controversial question what managers are thinking about coaching. The inquiry, developed in the Free University of Amsterdam, asks also for the expectations on coaching. The author finds out, that issues of leading take priority and that not only crises and conflicts are reasons to ask for a coaching, but also desires to improve the personal performance. 相似文献

Strategic decision‐makers today face complex environments with meta‐problems that cut across multiple industries. Single organizations cannot address these meta‐problems. As a result, organizations collaborate with partners, among them also competitors, and commonly work together in multi‐partner initiatives (MPIs). How these organizations jointly form an interorganizational strategy (IOS), however, is not well understood. In this paper, we extend the current strategy process conceptualizations from an intraorganizational focus of a single firm to an interorganizational process of multiple strategy‐making entities working together. We selected the eMobility sector as our research context to develop such an IOS process model. We first developed 25 cases on MPIs in the German‐speaking area based on interviews and desk research, before we focused on the eMobility ecology in the southern part of Germany. We identified 291 MPIs, conducted interviews with 19 central actors, held several workshops and informal gatherings, and complemented these data with an analysis of publicly accessible documents. Using an inductive research design, we developed a process model that unfolds in three phases: initiation, negotiation and execution. We reveal specific process dynamics in MPIs to be critical in the formation and manifestation of IOS. 相似文献
