In this paper I argue that we have been amiss in diagnosing the role played by government, which has exacerbated the housing problems afflicting low‐income households in Australia. However, I argue further we have placed too much faith in the capacity of managerial interventions to ameliorate what are far more deep‐rooted and systemic challenges. It is suggested that researchers need to adopt a more critical account of the conduct of contemporary government policy making, one that casts aside a view of the State as a benevolent agency whose primary objective is to ameliorate the conditions of the disadvantaged. Instead, the State should be understood as an agency that sustains the conditions necessary for the finance industry, developers and real estate agents, along with well‐off householders and landlords, to reap profits. The political economy of Australian housing, in its current incarnation, performs a form of reverse welfarism that exacerbates social inequality.  相似文献

Strategic technology alliance termination: An empirical investigation   总被引:1,自引:0,他引:1  
There is growing consensus that overall alliance termination rates are high. However, despite this track record of termination and despite unsurpassed growth rates of strategic technology alliances, little is known about the reasons for their termination. Typically strategic alliances have been characterized as inherently instable, i.e. often involving unplanned and premature termination of the alliance by partnering firms indicating alliance failure. The literature on strategic technology alliances, however, proposes that alliance termination does not always indicate failure, but can be intended and can be a sign of strength. We examine these different perceptions by using a sample of 48 strategic technology alliances in different high-technology industries. The findings in the paper confirm that the rates of termination are rather high for strategic technology alliances. Overall, we found that in particular negative prospects about future cooperation, negative perceptions about joint benefits and the lack of a win-win situation had an impact on the decision to terminate a strategic technology alliance. Also, the fact that some companies opt only for short-term (not for long-term and renewed) cooperation seems to introduce a negative factor into the longevity of strategic technology alliances.  相似文献

Missing data methods, maximum likelihood estimation (MLE) and multiple imputation (MI), for longitudinal questionnaire data were investigated via simulation. Predictive mean matching (PMM) was applied at both item and scale levels, logistic regression at item level and multivariate normal imputation at scale level. We investigated a hybrid approach which is combination of MLE and MI, i.e. scales from the imputed data are eliminated if all underlying items were originally missing. Bias and mean square error (MSE) for parameter estimates were examined. ML seemed to provide occasionally the best results in terms of bias, but hardly ever on MSE. All imputation methods at the scale level and logistic regression at item level hardly ever showed the best performance. The hybrid approach is similar or better than its original MI. The PMM-hybrid approach at item level demonstrated the best MSE for most settings and in some cases also the smallest bias.  相似文献

Missing data in clinical trials is a well‐known problem, and the classical statistical methods used can be overly simple. This case study shows how well‐established missing data theory can be applied to efficacy data collected in a long‐term open‐label trial with a discontinuation rate of almost 50%. Satisfaction with treatment in chronically constipated patients was the efficacy measure assessed at baseline and every 3 months postbaseline. The improvement in treatment satisfaction from baseline was originally analyzed with a paired t‐test ignoring missing data and discarding the correlation structure of the longitudinal data. As the original analysis started from missing completely at random assumptions regarding the missing data process, the satisfaction data were re‐examined, and several missing at random (MAR) and missing not at random (MNAR) techniques resulted in adjusted estimate for the improvement in satisfaction over 12 months. Throughout the different sensitivity analyses, the effect sizes remained significant and clinically relevant. Thus, even for an open‐label trial design, sensitivity analysis, with different assumptions for the nature of dropouts (MAR or MNAR) and with different classes of models (selection, pattern‐mixture, or multiple imputation models), has been found useful and provides evidence towards the robustness of the original analyses; additional sensitivity analyses could be undertaken to further qualify robustness.

Educational programs in human service professions such as social work, criminal justice, psychology, and public administration stress the importance of recognizing domestic/intimate partner violence as well as elder abuse. Students' abilities to recognize domestic violence in older couples have not been well-investigated. In this study, three vignettes were developed (Pat and Lee at age 75, Pat and Lee at age 30, Imagine yourself with Lee at age 75) in which intimate partner violence was perpetrated by the character Lee. Twenty-five items followed each vignette. When the variables of educational standing (graduate/undergraduate), ethnicity, and academic major were controlled, there were significant differences between the vignettes in 14 of 25 items (General Linear Model, F = 1.552, df = 50, p = .012). More than three out of four respondents for each vignette identified this as domestic violence and believed there was potential for serious harm. However, respondents were less likely to believe that a 75-year-old partner would know when to terminate a relationship in which there was intimate partner violence. Respondents who were asked to imagine themselves with Lee at 75 were likely to perceive Lee as more dangerous than respondents for the other vignettes. Implications are considered for educators.  相似文献

The transformation of social care in England is taking place though changes affording greater choice and control for people using services. Individual budgets were one key element of these changes and were piloted in 13 local authorities in 2006–2008. This article reports on interviews with training leads in these local authorities that took place in 2008 as part of an independent evaluation of the individual budget pilots. The aims of the interviews were to explore the role of training as part of the processes of transformation, the use of resources and establishment of training strategies within the local authority. Participants revealed that the subject of training was acquiring higher profile within their authorities, although uncertainties remain about the extent of local authority responsibilities for training. Within local authorities, training resources were yet to be determined and models of training were not fully developed. The article concludes that training will remain a central issue when implementing personalised social care services and that models of training for such changes should be shared and evaluated over the long term.  相似文献

This article examines the effect of product development restructuring (PDR) on shareholder value. The results are based on a sample of 165 announcements made during 2002–2011. PDR announcements are associated with an economically and statistically significant positive stock market reaction. Over a two‐day period (the day of the announcement and the day preceding the announcement), the mean (median) market reaction is 1.63% (0.87%). The market reaction is generally positive regardless of the PDR purpose or action. Although the market reaction is more positive for higher R&D intensity firms, it is not directly affected by the firm's prior financial performance or whether the firm's primary PDR objective is to increase revenues or cut costs. However, the interaction between the firm's prior financial performance and its primary PDR objective is significant. For firms that are financial outperformers, the market reaction is more positive if the firm's primary PDR objective is to increase revenues. For financial underperformers, the market reaction is more positive if the firm's primary PDR objective is to cut costs.  相似文献

The current economic and social context calls for a renewed assessment of the consequences of an early transition to parenthood. In interviews with 55 teenage mothers in Colorado, we find that they are experiencing severe economic and social strains. Financially, although most are receiving substantial help from family members and sometimes their children's fathers, basic needs often remain unmet. Macroeconomic and family structure trends have resulted in deprived material circumstances, while welfare reform and other changes have reduced the availability of aid. Socially, families' and communities' disapproval of early childbearing negatively influences the support young mothers receive, their social interactions, and their experiences with social institutions.  相似文献
