The term ‘end-to-end’ process management is now commonplace in the language and practice of operations. Managers are encouraged to migrate from functional process management to end-to-end process management to realise a range of performance improvements. However, these improvements are often elusive; the specific challenges associated with such a migration are under-researched. This paper uses a cross-sector study to identify the challenges of end-to-end process management and to generate practical managerial guidance. Three areas are identified that demand particular managerial attention: the need to move beyond process mapping, the role of IT in process management and maintaining the process infrastructure as a strategic asset. More significantly, the findings highlight the need for greater conceptual clarity regarding the end-to-end concept itself. The existing literature suggests that scope is the primary differentiator of the end-to-end process – the requirement to manage an extended boundary from customer order through to customer fulfilment. However, this research suggests that the end-to-end concept is more complex, comprising of three core constructs with seven dimensions: scope (boundary conditions, sequence/flow and controls); scale (resources and input/output transformation) and complexity (interrelationships and orientation). End-to-end process management involves much more than an extended boundary. It requires a systemic perspective and clarity regarding controls and transforming resources.  相似文献

EEG microstate analysis investigates the collection of distinct temporal blocks that characterize the electrical activity of the brain. Brain activity within each microstate is stable, but activity switches rapidly between different microstates in a nonrandom way. We propose a Bayesian nonparametric model that concurrently estimates the number of microstates and their underlying behaviour. We use a Markov switching vector autoregressive (VAR) framework, where a hidden Markov model (HMM) controls the nonrandom state switching dynamics of the EEG activity and a VAR model defines the behaviour of all time points within a given state. We analyze the resting‐state EEG data from twin pairs collected through the Minnesota Twin Family Study, consisting of 70 epochs per participant, where each epoch corresponds to 2 s of EEG data. We fit our model at the twin pair level, sharing information within epochs from the same participant and within epochs from the same twin pair. We capture within twin‐pair similarity, using an Indian buffet process, to consider an infinite library of microstates, allowing each participant to select a finite number of states from this library. The state spaces of highly similar twins may completely overlap while dissimilar twins could select distinct state spaces. In this way, our Bayesian nonparametric model defines a sparse set of states that describe the EEG data. All epochs from a single participant use the same set of states and are assumed to adhere to the same state switching dynamics in the HMM model, enforcing within‐participant similarity.  相似文献

托马斯·墨子刻(Thomas A.Metzger)指出,中国政治思想的解释者们必须在两个目标之间取得一种平衡:对背景和文化连续性的强调,以及对批判性反思和真理的强调.通过与他的著作和方法论的对话,本文展开了两个主要的论点.首先,笔者认为从罗伯特·布兰登(Robert Brandom)那里借用来的一种理解"话语"(discourse)和"约定"(commitment)的方式比墨子刻自己的方法论更为成功地应对了他所提出的可贵目标.其次,笔者区分了比较研究中的两种策略,也即对"包容性背景"(inclusive context)的强调以及对"分化"(disaggregation)的强调.文章建议,必须谨慎地运用我通过"分化"所标识的方法,人们应当始终清楚地意识到墨子刻所极力向我们表明的主张,进而掌握比较哲学的"分化"这一方法论策略.  相似文献

This article is a follow-up to our article 'Revisiting social work as art' and in part a response to Karen Healy's reply [both published in IJSW 17(2)]. It is, however, also a significant extension of this material since it engages with more general concerns about the critical project that is intrinsic to social work. Social work is not just about self-foundation based on knowledge, values and skills formation, but also about self-assertion. Crucially, it is through this notion of self-assertion that social work can be best understood as an agent of change. This transformative aspect of social work is our central focus. We are not concerned with structural conditions of power and domination but with theorising what a transformative politics would look like for social work using the lens of the French political philosopher Alain Badiou as a conceptual medium for permitting the return of the political for social work.  相似文献

We provide a reason for Bayesian updating, in the Bernoulli case, even when it is assumed that observations are independent and identically distributed with a fixed but unknown parameter θ0θ0. The motivation relies on the use of loss functions and asymptotics. Such a justification is important due to the recent interest and focus on Bayesian consistency which indeed assumes that the observations are independent and identically distributed rather than being conditionally independent with joint distribution depending on the choice of prior.  相似文献

This article explores differences in the self‐reported drug use and exposure to drugs of an ethnically diverse group of 408 seventh‐grade students from a large city in the southwest. We contrast the explanatory power of ethnic labels (African American, non‐Hispanic White, Mexican American, and mixed ethnicity) and two dimensions of ethnic identity in predicting drug use. One dimension focuses on perceived ethnically consistent behavior, speech, and looks, while the other gauges a sense of ethnic pride. Ethnic labels were found to be somewhat useful in identifying differences in drug use, but the two ethnic identity measures, by themselves, did not generally help to explain differences in drug use. In conjunction, however, ethnic labels and ethnic identity measures explained far more of the differences in drug use than either did alone. The findings indicate that the two dimensions of ethnic identity predict drug outcomes in opposite ways, and these relations are different for minority students and non‐Hispanic White students. Generally, African American, Mexican American, and mixed‐ethnicity students with a strong sense of ethnic pride reported less drug use and exposure, while ethnically proud White students reported more. Ethnic minority students who viewed their behavior, speech, and looks as consistent with their ethnic group reported more drug use and exposure, while their White counterparts reported less. These findings are discussed, and recommendations for future research are provided.  相似文献

This study investigates the experiences of lesbian and gay parents seeking health care for their children within the Australian medical system. Previously unavailable demographic data was collected on lesbian and gay families, and qualitative information was sought from parents about positive or problematic health care experiences related to sexual orientation and family constellation. Ninety-two lesbian or gay parents responded to a national postal and Web-based survey. Eighty-nine percent of respondents reported a high level of satisfaction with the health care received by their children. Despite overall satisfaction, however, 49 percent of parents identified fear of disclosure of sexual orientation, and 27 percent reported negative or problematic experiences with their children's health care related to sexual orientation or family constellation. This study indicates that fear of discrimination and homophobic attitudes towards lesbian and gay families remain a factor within the Australian health care system.  相似文献

This research note presents preliminary research into the relationship between the racial composition of public schools in school districts and the percentages of white students in nonpublic schools in those districts. Specifically, we ask two questions: Is the enrollment of whites in non‐public schools associated with minority predominance in public schools? Is there an association between the enrollment of whites outside of the public school system and the academic performance of students in the public school system? Using two‐ and three‐level hierarchical linear models, we find that school districts that have more whites in nonpublic schools tend to contain public schools with larger percentages of minority students. Further, at both the school and individual levels, achievement test scores tend to be lower in districts in which white students tend to be enrolled outside of the public school system. In addition, the achievement gap between white and minority students tends to be greater in districts with relatively more students in nonpublic schools. These findings are consistent with the argument that the withdrawal of white students from the public school system is negatively related to academic achievement because it tends to concentrate minority students in public schools.  相似文献
