Purpose The purpose of the paper is to present a theory of organisational change within the setting of a governmental bureaucracy. Design/methodology/approach Orthodox grounded theory is employed in the setting of a change programme in 12 Audit departments of the Dutch Ministries (public-sector). Findings The examined organisational change has specific characteristics. The Dutch ‘ministerial autonomy’ and the clearly recognizable role types of the key figures involved have a strong impact on the change programme and the realisation of its goals. Research limitations/implications Findings are derived on the basis of a substantive case study of the change programme of the Dutch Departmental Audit function. The research sheds new light on characteristics related to the occupational group of Chartered Accountants and characteristics of a governmental bureaucracy and it helps to understand change programmes within this bureaucracy. Practical implications The grounded theoretical model draws attention to the impact of key figures and circumstances on a change programme within the central government. Originality/value The paper builds on theories of organisational change but applies them in the typical context of the Dutch civil service where ministerial autonomy, on the one hand, and a move in the direction of more centrally organised activities (concern idea), on the other, require a difficult balancing act of all players in the change arena.  相似文献

This article summarizes a quantitative microbial risk assessment designed to characterize the public health impact of consumption of shell eggs and egg products contaminated with Salmonella Enteritidis (SE). This risk assessment's objectives were to: (1) establish the baseline risk of foodborne illness from SE, (2) identify and evaluate potential risk mitigation strategies, and (3) identify data gaps related to future research efforts. The risk assessment model has five modules. The Egg Production module estimates the number of eggs produced that are SE-contaminated. Shell Egg Processing, Egg Products Processing, and Preparation & Consumption modules estimate the increase or decrease in the numbers of SE organisms in eggs or egg products as they pass through storage, transportation, processing, and preparation. A Public Health Outcomes module then calculates the incidence of illnesses and four clinical outcomes, as well as the cases of reactive arthritis associated with SE infection following consumption. The baseline model estimates an average production of 2.3 million SE-contaminated shell eggs/year of the estimated 69 billion produced annually and predicts an average of 661,633, human illnesses per year from consumption of these eggs. The model estimates approximately 94% of these cases recover without medical care, 5% visit a physician, an additional 0.5% are hospitalized, and 0.05% result in death. The contribution of SE from commercially pasteurized egg products was estimated to be negligible. Five mitigation scenarios were selected for comparison of their individual and combined effects on the number of human illnesses. Results suggest that mitigation in only one segment of the farm-to-table continuum will be less effective than several applied in different segments. Key data gaps and areas for future research include the epidemiology of SE on farms, the bacteriology of SE in eggs, human behavior in food handling and preparation, and human responses to SE exposure.  相似文献

A Monte Carlo method is presented to study the effect of systematic and random errors on computer models mainly dealing with experimental data. It is a common assumption in this type of models (linear and nonlinear regression, and nonregression computer models) involving experimental measurements that the error sources are mainly random and independent with no constant background errors (systematic errors). However, from comparisons of different experimental data sources evidence is often found of significant bias or calibration errors. The uncertainty analysis approach presented in this work is based on the analysis of cumulative probability distributions for output variables of the models involved taking into account the effect of both types of errors. The probability distributions are obtained by performing Monte Carlo simulation coupled with appropriate definitions for the random and systematic errors. The main objectives are to detect the error source with stochastic dominance on the uncertainty propagation and the combined effect on output variables of the models. The results from the case studies analyzed show that the approach is able to distinguish which error type has a more significant effect on the performance of the model. Also, it was found that systematic or calibration errors, if present, cannot be neglected in uncertainty analysis of models dependent on experimental measurements such as chemical and physical properties. The approach can be used to facilitate decision making in fields related to safety factors selection, modeling, experimental data measurement, and experimental design.  相似文献

The purpose of this study was to develop a grounded theory of earning secure attachment. This study included 15 women and 5 men who met the criteria of having a self-reported history of attachment insecurity and demonstrated evidence of earned security. The grand tour research question, How do adults with a history of insecure attachment earn security?, was explored using constructivist grounded theory and semi-structured interviews emphasizing processes of positive attachment change. The results describe a process model of change hinging on three interrelated categories: meta-conditions of positive attachment change, making intrapsychic changes, and making interpersonal changes. Clinical implications include the importance of clients committing to the process, clients working with a clinician trained in trauma-focused therapy, and clinicians being surrogate attachment figures for clients.  相似文献

Managed care is changing the provision of services to clients and the availability of field placements for students. This exploratory study, reporting on an October 1996 survey of social work field directors nationwide, confirms that placements have been lost because of managed care. Yet, it also notes that schools and agencies are reassessing their relationship and can collaborate to create different learning opportunities in the new environment. The findings have implications for deans, program directors, field directors, and regional and national organizations (such as the Council on Social Work Education) in the areas of revising the curriculum, confronting student expectations, and establishing new relationships with agencies.  相似文献

Secondary analysis of Early Head Start Research and Evaluation Study longitudinal data explored family, parent, and child factors that contribute to the use of physical discipline with infants and toddlers. The sample included mothers (N = 1,580) who self reported the use of spanking at 14, 24, and 36 months. Eighteen percent of the mothers (n = 287) indicated that their children experienced consistent physical discipline. Data were analyzed using binary logistic regression. Participation in parenting classes resulted in a 30% reduction in the use of physical discipline. For every year older the mother was at the birth of the child, there was a 7% decrease in physical discipline. Increased knowledge of child development reduced spanking by 35%. Implications for social work practice with families of young children are discussed.  相似文献

Natural disasters are harmful worldwide events that inflict multiple psychosocial impacts on disaster-exposed individuals. A significant proportion of affected individuals are teenagers (13–18 years old) who, compared with adults, have been historically overlooked in disaster research. The literature is particularly sparse concerning teenagers’ recovery from natural disasters, specifically what recovery means to them and the contributing factors towards their positive recovery. Therefore, the aim of the current study was to gain deeper insight into this largely unexplored area by conducting five focus groups with teenagers (16–18 years) who experienced at least one of the Canterbury, New Zealand, earthquakes since and including the initial September 2010 earthquake. This study directly asked teenagers about their recovery over the three years after the initial earthquakes, with data being analysed using thematic analysis. Two main themes were identified: (1) perceptions of recovery, with three sub-themes (i) knowledge and being less frightened, (ii) talking about the earthquakes and (iii) shift in perspectives; and (2) contributing factors to recovery, with three sub-themes (i) participation in the community response, (ii) returning to school and (iii) the rebuild of Christchurch. These factors provide insight into how we can better support the recovery process for disaster-exposed teenagers to reduce long-term distress.  相似文献

This study aims to understand the associations between adult attachment security and different types of intimate partner violence victimization including that of emotional abuse, physical violence, and sexual coercion among heterosexual couples. Participants included 87 couples with the mean age 22.3 years. An actor–partner interdependence model was fit to the data. Findings indicated that adult attachment security accounted for 15% of the variance in the emotional abuse victimization of females, 9% of the variance in the sexual coercion victimization of females, and 7% of the variance in minor physical victimization of males. This may significantly impact risk factor assessment, and contribute to improved therapeutic intervention and increased understanding of the development and progression of relationship violence.  相似文献
