Shrinkage or ‘no growth’ is expected to condition the long-term perspective of many Western cities and regions. Planning for shrinkage differs substantively from planning for growth and therefore calls for a change of thought in spatial planning. In our paper, we analyse how planning professionals responded to a ‘planning for shrinkage’ challenge in a regional design competition. We found that they fully adapted to the shrinking perspective, took a strategic approach, and promoted a leading role for local inhabitants. Collaboration with local inhabitants and entrepreneurs, creating new alliances, and timing emerge as key themes for planning professionals in planning for shrinkage. 相似文献

Dominance plays an important part in police-civilian interactions. However, burnout is associated with a reduction in dominance, and this might, paradoxically, lead to more effective outcomes in conflict situations. There is a lack of knowledge about the effects of burnout in professional practice, and this multi-method study was conducted to better understand these dynamics. It is unique in that it combined self-reported burnout with observed behaviour in interactions with civilians. In this study, the relationships between the imbalance between demands and rewards, occupational burnout and police officers’ behaviour in conflict situations (in terms of dominance and effectiveness) were examined. A questionnaire was used to assess job demands, rewards and burnout among 358 Dutch police officers. In addition, police officers’ interactions with civilians were observed over 122 days. The results of structural equation modelling analyses showed that the imbalance between job demands and rewards was predictive of burnout (emotional exhaustion and depersonalization). Burnout, in its turn, predicted a decrease in dominant behaviour in conflict situations and, consequently, more effective conflict outcomes. These findings show that reduced dominance associated with burnout could in fact have positive consequences for professional behaviour in conflict situations. The benefits of reduced dominance in these situations should be taken into account in the training of professionals. 相似文献

This paper considers the problem of using control charts to simultaneously monitor more than one parameter with emphasis on simultaneously monitoring the mean and variance. Fixed sampling interval control charts are modified to use variable sampling intervals depending on what is being observed from the data. Two basic strategies are investigated. One strategy uses separate control charts for each parameter, A second strategy uses a proposed single combined statistic which is sensitive to shifts in both the mean and variance. Each procedure is compared to corresponding fixed interval procedures. It is seen that for both strategies the variable sampling interval approach is substantially more efficient than fixed interval procedures. 相似文献

We examine the orthogonality assumption of seasonal and nonseasonal components for official quarterly unemployment figures in Germany and the United States. Although nonperiodic correlations do not seem to reject the orthogonality assumption, a periodic analysis based on correlation functions that vary with the seasons indicates the violation of orthogonality. We find that the unadjusted data can be described by periodic autoregressive models with a unit root. In simulations we replicate the empirical findings for the German data, where we use these simple models to generate artificial samples. Multiplicative seasonal adjustment leads to large periodic correlations. Additive adjustment leads to smaller ones. 相似文献

Among persons at the end of life, it is important to understand whether the needs of patients are being adequately addressed. In particular, in hospice settings where the emphasis is on comfort care and quality of life, we know little about the presence of unmet needs. The purpose of this study was to examine the experiences of hospice social workers in working with hospice patients who had unmet needs at the end of life. Surveys were mailed to hospice social workers (N = 212) in two Southeastern states with a response rate of 36%. Results revealed that hospice social workers perceived patients to experience a wide variety of unmet needs-more commonly at the time of admission than during subsequent patient interactions. The most common unmet need reported at both times was a decreased ability to participate in activities that make life enjoyable. In situations where unmet needs exist, social workers reported that the most common perceived reasons were patient- related psychosocial issues and family conflict/issues. Additionally, a variety of interventions were used to address unmet needs, but a large number of barriers appear to impact outcomes in the cases. Results suggest that hospice patients experience a number of unmet needs, many of which are potentially treatable problems and concerns. Hospice professionals must continue to seek ways to assess and intervene effectively with patients who have unmet needs. 相似文献

Mixtures of skewed distributions (univariate and bivariate) provide flexible models. An alternative modeling approach involves distributions with skewed conditional distributions and mixtures of such distributions. We consider the interrelationships between such models. Examples are provided to show that several skewed distributions already considered in the literature can be viewed as having been constructed via a combination of mixing and skewing. 相似文献

AbstractThis article considers linear models with a spatial autoregressive error structure. Extending Arnold and Wied (2010), who develop an improved generalized method of moment (GMM) estimator for the parameters of the disturbance process to reduce the bias of existing estimation approaches, we establish the asymptotic normality of a new weighted version of this improved estimator and derive the efficient weighting matrix. We also show that this efficiently weighted GMM estimator is feasible as long as the regression matrix of the underlying linear model is non stochastic and illustrate the performance of the new estimator by a Monte Carlo simulation and an application to real data. 相似文献

Consider Motzkin paths which are lattice paths in the plane starting at the origin, running weakly above the x-axis and after n unit steps returning at the point (n,0). The allowed steps are the up and down steps (1,1) and (1,−1) respectively and certain horizontal steps. We consider two types of horizontal steps that have attracted recent attention in the literature. First, we consider unit horizontal steps (1,0) coloured with k colours, secondly, we look at paths where the horizontal steps are of length k, for a non-negative integer k. Using generating functions, we study the sum of heights of such paths of size n. With the use of the Mellin transform, we find asymptotic expressions for the mean heights as n tends to infinity. 相似文献

A recently developed statistical model, called Bayesian vector autoregression, has proven to be a useful tool for economic forecasting. Such a model today forecasts a strong resurgence of growth in the second half of 1985 and in 1986. 相似文献
