Analysis of covariance in mixed models with unequal subclass numbers

Blue of estimable linear functions and exact tests of hypotheses concerning such functions usually do not exist in the covariance model with random factors having unknown variances. This is true even in the equal subclass numbers case. This paper suggests alternative methods for finding linear unbiased estimators and presents methods for computing sampling variances which are linear functions of the unknown parameter variances. Also, higher level covariates are defined and nonestimability problems resulting from association of such covariates with fixed factors are discussed.     

Academy of Human Resource Development

Abstract

This non-refereed contribution to Human Resource Development International represents the reflections of three US delegates who attended the 6th International Conference on HRD Research and Practice across Europe in Leeds, England, in May 2005. We begin by providing an overview of the conference programme, examine the conference theme as reflected in the scholarship presented at the conference and share our impressions of the conference atmosphere. We conclude with some final thoughts.     

Tracing the legacy of Anita Hill: The Thomas/Hill hearings and media coverage of sexual harassment

Many anecdotal accounts suggest that the Clarence Thomas/Anita Hill hearings had an important effect on the politics of sexual harassment allegations. This research examines one part of this phenomenon, reporting the results of content analysis of articles published in major newspapers the month after reports of allegations against Bob packwood and Bill Clinton. Our data analysis provides a preliminary look at the continued significance of the Hill/Thomas case today and how it affects public discourse about sexual harassment, providing strong evidence that Anita Hill has indeed found a place in modern American political history as a symbol for the sexual harassment issue. Clearly, the hearings have significantly impacted the ways in which the media and the public view allegations of sexual harassment brought against political figures. She is currently serving as a 2000–2001 APSA Congressional Fellow.     

Rasch Analysis of the Metacognitive Awareness Listening Questionnaire (MALQ)

A valid metacognitive awareness second language (L2) listening questionnaire is important for both researchers and teachers to facilitate the measurement of language learners’ ability to reflect on and direct their L2 learning. However, very few metacognitive awareness questionnaires have been validated, particularly in the area of L2 listening (cf., Vandergrift, Goh, Mareschal, & Tafaghodtari, 2006). The Metacognitive Awareness Listening Questionnaire (MALQ) (Vandergrift et al.) is one exception. However, very little information has been collected on the MALQ’s psychometric properties. To address this paucity, we administered the MALQ to a sample of 299 male Korean adolescent speakers of English. Using a modern measurement approach to scale validation (Rasch modeling), we found that with the exception of one subscale (Person knowledge) the subscales had good psychometric properties in that it was reliable and unidimensional.     

A Year Then Forever: Personal Resolution Making and the Temporal Bridge of the Near Future

Based on in-depth interviews and drawing exercises with 25 resolution makers, this paper explores the use of time in structuring and enacting improvement projects of the self. Resolutions are intentional, identity-laden moments when people bring the future into the present. They provide a window into the identity work of the “near future”—an underresearched but fascinating site where individuals transition between what they see as an immediate, controllable future to a more distant one that is less certain. In attempt to mitigate the emotionally and cognitively daunting prospects of the distant future, resolution makers enlist time as a form of capital, constructing the “temporal bridge” of the near future by engaging in three interrelated processes: structuring and remembering, being flexible, and maintaining optimism.     

Institutions and Policies for Pro‐poor Agricultural Growth

Global experience with pro‐poor growth and empirical work spanning India, Malawi and Zimbabwe demonstrates the importance of agricultural growth for poverty reduction in poor rural areas, while also pointing to the need for complementary non‐farm sector growth. Theoretical arguments, historical evidence and livelihoods modelling in poor medium‐potential rural economies suggest that, contrary to thinking dominating much of current development policy, subsidies to relieve critical seasonal credit and cash restraints and reduce market and input supply uncertainties need to help in ‘kick‐starting’ agricultural markets if increased smallholder productivity in food‐grains is to drive rural non‐farm growth. Establishing the base conditions for these to work, designing and implementing them to be effective, and then phasing them out are major challenges facing policymakers.     

Analysis of longitudinal data with drop-out: objectives, assumptions and a proposal

Summary. The problem of analysing longitudinal data that are complicated by possibly informative drop-out has received considerable attention in the statistical literature. Most researchers have concentrated on either methodology or application, but we begin this paper by arguing that more attention could be given to study objectives and to the relevant targets for inference. Next we summarize a variety of approaches that have been suggested for dealing with drop-out. A long-standing concern in this subject area is that all methods require untestable assumptions. We discuss circumstances in which we are willing to make such assumptions and we propose a new and computationally efficient modelling and analysis procedure for these situations. We assume a dynamic linear model for the expected increments of a constructed variable, under which subject-specific random effects follow a martingale process in the absence of drop-out. Informal diagnostic procedures to assess the tenability of the assumption are proposed. The paper is completed by simulations and a comparison of our method and several alternatives in the analysis of data from a trial into the treatment of schizophrenia, in which approximately 50% of recruited subjects dropped out before the final scheduled measurement time.     

The impact of welfare reform on the parenting role of women in rural communities

Current family policy suggests that in order to restore family values we, as a society, need to focus on reviving a child-centered household. Full-time mothering is lauded as an honorable choice that will advance this goal and ultimately strengthen traditional family values. However, current welfare policy is contrary to this notion in that mandatory welfare-to-work programs deny women receiving public assistance the choice to be full-time mothers. Based on in-depth interviews with female welfare recipients in four rural Appalachian counties, this paper evaluates the problems women face as they confront the difficult choices of being either a “good mother” or a “good recipient.” From a feminist perspective, findings suggest that welfare reform programs in rural communities have put poor women in a proverbial “catch-22” with regard to effective parenting. Although many of the women strive to be ideal mothers as defined by societal standards, they often find that they cannot carry out the role effectively because of welfare reform regulations.     

NGOS AND THE DEVELOPMENT OF CIVIL SOCIETY IN BULGARIA AND THE USA

This study examines the development of civil society and its ability to facilitate stronger democratic practices in Bulgaria using the USA as a comparison. Using data gathered from surveys of NGOs in 2006, we examine three sets of questions. First, what is the level of NGO organizational capacity? Second, to what degree are NGOs performing their mediating roles? Third, how do NGOs perceive their effectiveness in working with the state and its citizens. Our findings suggest that Bulgarian NGOs face a number of challenges when compared with US NGOs, which affect their ability to engage in civil society activities such as establishing horizontal ties with citizens and other groups.
