No going back: A review of the literature on sustaining organizational change

Why do some organizational changes persist, while others decay? The sustainability of change can be defined broadly as the process through which new working methods, performance goals and improvement trajectories are maintained for a period appropriate to a given context. However, sustainability has received limited attention, although the concept reflects Lewin's concern with ‘refreezing’ ( Lewin. K. 1951 . Field Theory in Social Science: Selected Theoretical Papers by Kurt Lewin, UK edition published 1952, ed. D. Cartwright, London: Tavistock). In an uncertain environment, working practices that fail to adapt are targets for change, and stability has been regarded not as a condition to be achieved, but as a symptom of inertia, a problem to be solved. This paper reviews the emerging literature, seeking to develop a provisional model of the processes influencing change sustainability and decay, as a platform for further research. This review suggests that sustainability is dependent on multiple factors, at different levels of analysis: substantial, individual, managerial, financial, leadership, organizational, cultural, political, processual, contextual and temporal. The relative significance of those factors cannot be determined a priori, raising questions concerning the properties of the sustainability process with regard to different types of change in different contexts.     

Social Engagement and Immigration Attitudes: Panel Survey Evidence from Germany

This article asks how social engagement influences individuals' immigration concerns. Rates of volunteering, churchgoing, socializing, and helping others are used to predict anti‐immigration sentiments. Panel survey data from Germany makes a dynamic “conditional change” modeling strategy possible; lagged immigration views are included in models to reveal the predictors of over time developments. The most robust findings signal that frequent church attendance reduces immigration concerns; routinely helping others enhances them. And in both instances, these relationships are conditioned by the presence of immigrants in the residential area. Overall, the results position social participation in certain activities as important factors that shape people's views on immigration.     

How a Navigation Channel Contributed to Most of the Flooding of New Orleans During Hurricane Katrina

Levee failures during Hurricane Katrina left 85% of New Orleans flooded, 1,500 dead, and about 400,000 homeless. Three separate investigations into the levee failures have been concluded, yet none of these studies conclusively determined why the St Bernard polder flooded so deeply, despite Team Louisiana’s conclusion regarding early failure of the Mississippi River Gulf Outlet (MRGO) levees. Detailed wave and hydrodynamic modeling reported here reveals the cause of extensive breaching of the MRGO levees and how that created a very efficient conduit of surge water into the heart of the city.     

The Intrusiveness of Home-Based Work on Family Life

This research is intended to ascertain factors related to intrusion of home-based work into the life of the family, and identify the relative impact of characteristics of the home-based worker, his or her family, and the business on intrusions. Logistic regression was used to examine three types of intrusions. Seeing clients at home more than once a week is almost exclusively a function of the characteristics of the work; receiving telephone calls daily and frequently sharing space are functions of the characteristics of the work and of the worker. Understanding the nature of intrusions can help advise families contemplating home-based work and help home-working families find a balance between family demands and work.     

Quantitative alternatives to narrative reviews for understanding existing research literature

This article is the second in a series that examine the role of literature reviews in rehabilitation research. Methods of generating new knowledge from existing literature are categorized into three approaches: synthetic literature reviews which interpret previous findings in narrative fashion, quantitative literature reviews which summarize findings from primary research studies using a variety "counting" approaches, and meta-analyses which aggregate effect sizes from primary research studies and allow for a more complex analysis of trends in the empirical research literature. This articles examines the role that quantitative literature reviews can play in better understanding the status of knowledge in rehabilitation research, thereby shaping field practices as well as future scientific investigations. Examples of quantitative reviews from contemporary rehabilitation and related health sciences literature are provided throughout the article.     

Job design and levels of physical and mental strain among Australian prison officers

Over the past 15 years much has been made of the moderating influence of job discretion and support in occupations that are perceived to be high in demands. Such an effect seems to be most prevalent when subject populations are large and heterogeneous. One aim of this study was to examine the influence of subjective perceptions of these variables on strain reactions among a group of relatively homogeneous workers such as, in the present study, prison officers (n = 274). A second aim was to extend previous research and examine the joint influence of negative affectivity and perceptions of demands, discretion, and support on mental and physical well-being. It was hypothesized that those high in negative affect would be particularly strained by jobs perceived as being demanding. The hypothesized relationship between job demands, discretion and support were found to be weak and at times inconsistent. Social support, in particular, was found to have both positive and negative consequences for different aspects of well-being. Those high in negative affect were in general found to suffer lower mental well-being. More importantly, the interactive effect of negative affectivity and job demands was found to significantly predict the majority of the dependent variables used in this study. The valences of these relationships were inconsistent and are interpreted in light of Warr's (1987) vitamin model of stress.

There are several conclusions that can be drawn from the present study. Negative affectivity appears to have a truly interactive effect with job components, job demands in particular, to influence a range of variables relating to physical and mental health as well a job-related attitudes. The nature of these effects, however, suggests a dissociation in the ways that different independent variables influence a range of indices of well-being and affect. This result requires further investigation since there are important theoretical implications which will follow if the data are replicable.

In order to examine such complex effects, in addition to the need for more longitudinal studies, it is also important that standardized measures of job components are developed so that levels of stress exposure can be equated and their impact assessed across organizational settings.

Finally, the data reported in this study suggest that some effective stress management may be undertaken by adopting selection strategies which take into consideration individual characteristics. In view of the fact that individual stress management programmes are of unproven benefit (Murphy 1986, 1988) such an approach is recommended especially for those organizations which are highly constrained in the services that must be performed.     

Welfare reform and female headship

While much of the focus of recent welfare reforms has been on moving recipients from welfare to work, many reforms were also directed at decisions regarding living arrangements, pregnancy, marriage, and cohabitation. This article assesses the impact of welfare reform waivers and Temporary Assistance for Needy Families (TANF) programs on women's decisions to become unmarried heads of families, controlling for confounding influences from local economic and social conditions. We pooled data from the 1990, 1992, 1993, and 1996 panels of the Survey of Income and Program Participation, which span the period when many states began to adopt welfare waivers and to implement TANF, and estimated logit models of the incidence of female headship and state-stratified, Cox proportional hazard models of the rates of entry into and exit from headship. We found little consistent evidence that waivers affected female headship of families.

This paper illustrates how multivariate spectral analysis can be used to analyze complex, dynamic, business systems. Important temporal aspects of multiple time series are captured in the frequency domain by the coherence, phase, and gain statistics. A computer simulation of a time domain model produces sample results which demonstrate how the timing relations between two series can be reversed when the effects common to both series are partialled out. Finally, an empirical multivariate analysis of beef prices is used to determine the timing relations among prices at different levels of the production-distribution system.
