On the use of partial confounding for the construction of alternative regular two-level blocked fractional factorial designs

In this paper, we consider experimental situations in which a regular fractional factorial design is to be used to study the effects of m two-level factors using n=2^m−k experimental units arranged in 2^p blocks of size 2^m−k−p. In such situations, two-factor interactions are often confounded with blocks and complete information is lost on these two-factor interactions. Here we consider the use of the foldover technique in conjunction with combining designs having different blocking schemes to produce alternative partially confounded blocked fractional factorial designs that have more estimable two-factor interactions or a higher estimation capacity or both than their traditional counterparts.     

From the Third Sector to the Big Society: How Changing UK Government Policies Have Eroded Third Sector Trust

This article draws on concepts of trust to analyse recent policies affecting public/third sector relationships, examining competition, ‘command and control’ mechanisms and the community turn in shaping cultures of relationships. Drawing on examples from empirical studies in two English inner-city areas we explore ways in which power and controls exerted through dominant organisational cultures and arrangements undermine independent approaches, innovation and organisational learning across sectors. State bodies have taken trust in their actions as given while shifting responsibilities for service delivery and risks of failure to others. We argue that increasing market cultures and regulation have damaged cross-sector trust promoting divisive interests and risk-averse behaviours, restricting the local autonomy, innovation and community action presumed in the Big Society agenda. We conclude by highlighting issues that need to be addressed to ensure future collaboration with community-based providers; these include a focus on the processes and relational spaces which enable alternatives.

Planning for the delivery of special services in public schools : A multidimensional needs assessment framework

Public Law 94–142 requires that public school districts provide special service programs to handicapped and potentially handicapped children with diverse psychological, educational, and physical needs. In order for such programs to be developed and implemented in an appropriate and timely manner, procedures for assessment of pupil needs as well as assessment of school district resources that might address those needs, have been considered as important service delivery prerequisites. Toward that end, a Multidimensional Needs Assessment Framework, which has been developed by the authors and used in numerous public schools, is described in this paper. The Framework, which allows needs assessment to be seen as an integral part of the program planning process, requires that needs assessment and program planning activities occur in relation to three distinct, yet interrelated dimensions: Special Service Recipients, Special Service Resources, and Organizational Unit. Considerations necessary for design and implementation of needs assessment using the Framework are discussed, and suggestions for further development of the approach are noted.     

Experiments with incentives in telephone surveys

In an effort to counter the problem of noncooperation, survey organizations are offering incentives to respondents with increasing frequency, some at the outset of the survey, as has traditionally been done in mail surveys, and some only after the person has refused, in an attempt to convert the refusal. This article reports on a series of experiments carried out over a period of about 2 years with a monthly telephone survey, the Survey of Consumer Attitudes, in an effort to increase response rates or reduce interviewer effort. We report on experiments with prepaid versus promised incentives; advance letters; and advance letters with prepaid incentives; and we also report on the effects of incentives on response quality, sample composition, response bias, interviewer and respondent expectations, and costs.     

Family and sociodemographic influences on patterns of leaving home in Postwar Britain

We identify child-level and parent-level characteristics associated with children’s patterns of leaving home. We use a multilevel discrete-time hazards model to examine the impact of family and demographic factors at both levels, and utilize the Alternating Conditional Expectation algorithm optimally to transform the dependent and independent variables. We find that measured variables at both the child and the parent level have important influences, as do period and cohort factors. However, unmeasured parent-level factors have an influence on the departure of children that is broadly similar in magnitude to measured factors.
