The terms sweeping and alignment refer to the same process. Sweeping/alignment is used by data analysts as a technique for describing the effects of a model factor (e.g., treatments in a randomized block design) after the effects of nuisance parameters (e.g., blocks) have been removed from the data. In this paper sweeping/alignment is used as the basis for developing tests of factors in unbalanced experimental design models. Formulas are presented for treatment effects in randomized block designs with missing observations, and for interaction and main effects in unbalanced two-way factorial designs with empty cells. 相似文献

The maximum likelihood (ML) equations calculated from censored normal samples do not admit explicit solutions. A principle of modification is given and modified maximum likelihood (MML) equations, which admit explicit solutions, are defined. This approach makes it possible to tackle the hitherto unresolved problem of estimating and testing hypotheses about group-effects in one-way classification experimental designs based on Type I censored normal samples. The MML estimators of group-effects are obtained as explicit functions of sample observations and shown to be asymptotically identical with the ML estimators and hence BAN (best asymptotic normal) estimators. A statistic t is defined to test a linear contrast of group-effects and shown to be asymptotically normally distributed. A numerical example is presented which illustrates the procedure. 相似文献

ABSTRACTAn enduring challenge for HRD is ensuring academic research achieves impact on professional practice. We have located this research within debates about the research-practice gap. To investigate this challenge, we analyse case studies of academic impact from all disciplines submitted to the United Kingdom’s 2014 research assessment exercise (REF 2014). We found that Learning and Development was a primary focus of significant number of impact case studies submitted across all disciplines compared to other areas of HR and HRD. We also found that Learning and Development was a key path to Impact. These findings reveal that Learning and Development in a work context plays a pivotal role in helping researchers irrespective of discipline achieve impact. Our findings therefore speak to the research-practice gap across academia. We conclude by considering the potential role for HRD in generating impact. 相似文献

This paper explores the role and importance of the relationship in the treatment of a young foster child. Because of parental neglect and loss, the child related in an inauthentic manner in order to engage her parents. Her manner of relating arose from old patterns, which were defensive adaptations to traumatic situations. The authors employ a relational theory of the self to conceptualize the processes from an intrapsychic and interpersonal perspective. The paper emphasizes that all the interactions between child and therapist, both in and out of the traditional therapy office, converged into a multidimensional authentic relationship. The authors define this relationship experience as the life space and believe that the establishment of the life space contributed to progress in the therapy. 相似文献

This paper is based on research carried out at the Institute of Local Government Studies at the University of Birmingham. Policy Planning Systems are ways of dealing with the division of functions between central and local government and they provide a structure for the flow of information by means of specified procedures and processes. As this tends to create an increased flow of work, this area of planning is threatened by central and local government cut-backs in expenditures and manpower, and may well only survive by a positive demostration of its usefulness. 相似文献
