Approximate and exact distributions of rank tests for balanced incomplete block designs

Judges rank k out of t objects according to m replic ations of abasic balanced incomplete block design with bblocks. In Alvo and Cabilio(1991),it is shown that the Durbin test, which is the usual test in this situation, can be written in terms of Spearman correlations between the blocks, and using a Kendall correlation, they generated a new statistic for this situation.This Kendall tau based statistic has a richer support than the Durbin statistic, and is at least as efficient.In the present paper,exact and simulation based tables are generated for both statistics, and various approximations to these null distributions are considered and compared.     

Dialog als kreativer Denkraum in lernenden Organisationen

Dialogue — a space for creative thinking in learning organisationsToday almost every enterprise or institution has to face growing pressure, has to deal with unexpected unusual problems which cannot be solved by conventional standard strategies. New creative ways to diagnose and solve expected problems are to be found and integrated. Thus can dialogue be a useful instrument? And if this is the case, how can this unusual form of discussion be integrated into the daily fully-organized life? Can dialogue essentially change culture and communication in an enterprise? An empirical study carried out at two international companies allows us the gain an insight into the companies and shows us possible ways.     

Wissen managen in Wirtschaftsunternehmen

Since our society has developed to a so called knowledge society, businesses are increasingly recommended to use their knowledge resources in an effective and goal-oriented way in order to ensure their competitiveness and survivability. For this purpose, the choice of instruments should be based on the specific areas and requirements that knowledge management should find answers to.Taking into consideration the success prerequisites and avoiding failure traps can make knowledge management provide valuable and often fallow richness.     

A Cautionary Note on the Use of the Grønnesby and Borgan Goodness-of-Fit Test for the Cox Proportional Hazards Model

Grønnesby and Borgan (1996, Lifetime Data Analysis 2, 315–328) propose an omnibus goodness-of-fit test for the Cox proportional hazards model. The test is based on grouping the subjects by their estimated risk score and comparing the number of observed and a model based estimated number of expected events within each group. We show, using extensive simulations, that even for moderate sample sizes the choice of number of groups is critical for the test to attain the specified size. In light of these results we suggest a grouping strategy under which the test attains the correct size even for small samples. The power of the test statistic seems to be acceptable when compared to other goodness-of-fit tests.     

Zur Bedeutung der Supervision bei stationärer Psychotherapie am Beispiel von psychosomatischen Kliniken

The importance of supervision in inpatient psychotherapy settings such as hospitals for behavioral medicineThis article deals with the organization of supervision in hospitals that offer intensive inpatient psychotherapy (hospitals for behavioral medicine). The ?integrative model“ for supervision proposed by A. Schreyögg (1991) constitutes the theoretical basis. The author discusses the qualification of supervisors as well as aspects of different approaches to supervision, such as the psychoanalytical and the cognitive-behavioral approach. In doing so, she puts primary importance on the reflection of issues on the systemic, i.e. organizational level. At the end, a model for the organization of qualified internal supervision is proposed.     

Evaluation of the Neurodegenerative Conditions Coordinated Care Program (NCCCP) in Western Australia: barriers to better service provision

This paper details a 2009-2010 evaluation of the Neurodegenerative Conditions Coordinated Care Program (NCCCP) commissioned by the Disability Services Commission (DSC) in Western Australia (WA). The program, run by the Multiple Sclerosis Society of WA (Inc.) provides in-home care and supports and respite for people who are under the age of sixty-five and diagnosed with a rapidly degenerative neurological condition. In 2009, the identified barriers to the better provision of services included: shortage of quality out-of-home respite providers, and convoluted paperwork requirements to qualify for the program. Some service providers were unaware of the program and so were not referring them into the NCCCP, a number of service providers were unwilling to refer their clients into the program, neurologists were unwilling to give a final diagnosis for a client, that would enable them to qualify for the service, there was a general lack of knowledge about what services were available in the general community, and existing equipment pools were under-resourced. In 2010, the study found that most of the issues had been addressed however, out-of-home respite services were still very limited especially in rural areas, and the eligibility criteria for entry to the program is confined to those 65 years and under. This paper discusses the issues that still remain with the program as examples of barriers to better provision of services.     

Evaluation of the mandatory construction induction training program in Western Australia: unanticipated consequences

Since January 1, 2007, Government legislation in Western Australia required all workers in construction to complete mandatory safety awareness training before they began work on site. During the implementation of this new legislation there was considerable resistance from the construction sector due to the mandatory nature of the training. The construction industry viewed this as an unnecessary impost as they considered that there was already sufficient safety training delivered through individual company and site inductions. In 2010, we evaluated the new Construction Induction Training (CIT) in the commercial construction sector in Western Australia to find that since 2007 there has been an unanticipated change in support for the mandatory training. The 2010 study shows a shift in the values of the safety culture for the commercial sector of the construction industry. In 2010, the industry not only supports the mandatory CIT, but is very vocal in its request to re-institute the refresher courses that were withdrawn in 2009. Indeed, 79% of respondents claimed there were measurable benefits to their business having their employees complete the CIT, while 96% claimed the CIT assisted in reducing accidents/incidents on their worksites. This 2010 study indicates that in this case, mandatory training has had a positive effect on safety culture change and gradually reduced work-related injury in the industry since 2007 to the present. The paper uses data from two studies conducted in 2006 and 2010 to highlight the unanticipated change in perception of the value of mandatory safety training in the WA construction industry to one which is positive and supportive.     

„Nem Kind nun vorzumachen, du kriegst’ ne Lehrstelle, ist für mich unrealistisch.“

Subject of this contribution are the strategies of action and the practices of social binding under the condition of precarious employment relations. In the case of a young retail saleswoman I want to explore the question if and how situations of insecurity and uncertainty produce specific habitual changes and acquisitions. Which significance do discontinuous life courses have on biographical self-construction? How do the practices of everyday life and the relation to an uncertain future differ between the younger generation and their parents? And finally: which consequences do the pragmatic use of chance and contingency have on lived gender arrangements?     

Bespoke program design for school-aged therapy disability service delivery

This article uses the evaluation of a school-aged therapy service for children with disabilities in Western Australia to investigate models of service delivery. The current literature on family-centered practice, multidisciplinary and transdisciplinary approaches, and 4 models of service are reviewed. The models include the life needs model, the relational goal-orientated model of optimal service delivery to children and families, the quality of life model, and the collaborative model of service delivery. Analysis of the data is presented together with a bespoke model of service delivery for children with disabilities, arguing that local contexts benefit from custom-made service design.
