Träume im Coaching Ein Beispiel und ein Leitfaden für kollegiale Traumdialoge

Dreams in Coaching. A case study and a guide for dialogues on dreamsAn approach to dreams is offered, that invites consultant into working with dreams even if they are not trained as psychologists. Through an intuitive and creative dialogue with images the consultant as well as the client come into a dialogue with their unconscious perceptions of the development. While discussing the process of a specific case it will be shown how working with dreams helps to understand, to shape, and to control. Hereby it will be illustrated how the consultant can do it and how things relate to each other. Finally an guide for dialogues on dreams describes useful attitudes, questions and experiments in working with dreams.     

Charting small sample characteristics of asymptotic confidence intervals for the binomial parameterp

Small sample properties of seven confidence intervals for the binomial parameterp (based on various normal approximations) and of the Clopper-Pearson interval are compared. Coverage probabilities and expected lower and upper limits of the intervals are graphically displayed as functions of the binomial parameterp for various sample sizes.     

On the existence of unbiased estimators for the portfolio weights obtained by maximizing the Sharpe ratio

We consider the problem of estimating the portfolio weights obtained by maximizing the Sharpe ratio. Assuming that the underlying asset returns are independent and multivariate normally distributed, Okhrin and Schmid (J. Econom. 134:235–256, 2006) showed that the frequently used sample estimators of these weights do not have a first moment. This paper proves that an unbiased estimator of the Sharpe ratio portfolio weights does not exist at all. Moreover, we show that there is no asymptotically unbiased estimator of these weights within the family of estimators which are bounded by cylinder functions.     

Spatio-temporal statistical analysis of the carbon budget of the terrestrial ecosystem

The Net Ecosystem Exchange describes the net carbon dioxide flux between an ecosystem and the atmosphere and is a key quantity in climate change studies and in political negotiations. This paper provides a spatio-temporal statistical framework, which is able to infer the Net Ecosystem Exchange from remotely-sensed carbon dioxide ground concentrations together with data on the Normalized Difference Vegetation Index, the Gross Primary Production and the land cover classification. The model is based on spatial and temporal latent random effects, that act as space–time varying coefficients, which allows for a flexible modeling of the spatio-temporal auto- and cross-correlation structure. The intra- and inter-annual variations of the Net Ecosystem Exchange are evaluated and dynamic maps are provided on a nearly global grid and in intervals of 16 days.     

Sequential monitoring of high-dimensional time series

In the paper we derive new types of multivariate exponentially weighted moving average (EWMA) control charts which are based on the Euclidean distance and on the distance defined by using the inverse of the diagonal matrix consisting of the variances. The design of the proposed control schemes does not involve the computation of the inverse covariance matrix and, thus, it can be used in the high-dimensional setting. The distributional properties of the control statistics are obtained and are used in the determination of the new control procedures. Within an extensive simulation study, the new approaches are compared with the multivariate EWMA control charts which are based on the Mahalanobis distance.     

The Critical Role of the Initial Stages of Cross-Sector Partnerships and Their Implications for Partnerships’ Outcomes

The paper presents research findings on the initial stages of the life cycle of cross-sector partnerships in the social services. The findings clearly show the importance and impact of the initial stages on the establishment and institutionalization of the partnerships over time. These stages are mainly characterized by clarifying the common goals of the partnership, mobilizing support to achieve the goals, overcoming resistance and relieving fears while convincing opponents to change their attitudes toward the partnership, and formalizing and constructing administrative processes and procedures. Special attention is given to the emotional energy that the management and workers invest in the initial stages in order to overcome barriers as well as ideological, cultural, and procedural gaps between the partner organizations. The relationships between selected organizational properties that typify the initial stages of cross-sector partnerships and the achievement of goals and outcomes are presented, analyzed, and discussed.

     

The Multiple Outlier Problem in Time Series Analysis

In this paper we consider the multiple outlier problem in time series analysis. The underlying undisturbed time series is assumed to be an autoregressive process. The location of the suspicious values is supposed to be known. We introduce conditional least squares estimators for the parameters. The estimates are shown to be strongly consistent. Using similar arguments as in the theory of linear models, we get a test statistic for the general linear hypothesis. Its asymptotic distribution is derived.     

Public attitudes toward the identification and reporting of alleged maltreatment cases among social groups in Israel

Objectives

To identify what types of behaviors are defined as child maltreatment by the Israeli public, and which types of incidences are seen as justifying reporting to the authorities. The study examines to what extent these views are different among social groups in the Israeli society (e.g., Arabs and ultra-Orthodox).

Methods

A telephone survey was conducted among a representative sample of 812 adults in Israel, with an oversampling of additional 50 ultra-Orthodox Jews. A series of 12 scenarios was presented to respondents who indicated whether each of them was a case of maltreatment and whether it justified reporting to authorities.

Results

There was strong consensus among the participants that some scenarios indicate maltreatment. These scenarios related to all types of maltreatment and were associated with potentially severe harm. The tendency to justify reporting is weaker than the tendency to see them as cases of maltreatment. Further, there is a correspondence (although not a perfect one) between to what extent scenarios are judged as more indicative of maltreatment and the extent to which they are seen as justifying reporting. Both Arabs and ultra-Orthodox Jews tend to see more maltreatment than Jews in general and non ultra-Orthodox Jews in particular, except for using corporal punishment to “educate” an insolent child. No consistent differences were found between these groups in their justification for reporting.

Conclusions

There are indications that the underlying dimension which determines the identification of cases as maltreatment and justifies reporting is the severity of the potential harm to child, rather than the type of maltreatment (i.e., physical, sexual, neglect or emotional). The authors suggest that public campaigns should be tailored to address the different attitudes and perspectives of different social-cultural groups.
