Governance structures constrain and enable the actions of public managers. Principal–agent theory has played a dominant role in our understanding of governance structures. This theory suggests that politicians create relatively static governance structures in a top–down fashion and hold managers accountable for mandated results. In other words, public managers are influenced by governance structures but do not affect governance structures. However, we argue that public managers do affect governance structures, and, in order to understand how this influence takes place, we need a new way of thinking about governance structures. We propose thinking about governance structures as relationships created through the interactions of people in different and reciprocal roles that are relatively dynamic. Public managers are an important source of the multiple, reciprocal, and dynamic interactions that produce governance (relationship) structures. As such, managers are accountable not only for policy outcomes, but also for the appropriateness of the relationships they create and support.  相似文献

The Festival of the Holy Spirit was considered the most important religious celebration in nineteenth‐century Rio de Janeiro. I discuss the popular practices of music, dance and theatre during the festival. By merging European waltz and the African batuque, the heterogeneous public re‐created and re‐invented a number of new genres that are at the roots of twentieth‐century Brazilian popular music. The festival of the Holy Spirit allows an examination of elite strategies and municipal policies regarding popular culture. In this respect, it is remarkable how much political use the Brazilian Empire made of the festival of the Holy Spirit and how its revellers fought for their celebration.  相似文献

Coding statements of criminal suspects facilitated tests of four hypotheses about differences between behavioral cues to deception and the incriminating potential (IP) of the topic. Information from criminal investigations corroborated the veracity of 337 brief utterances from 28 videotaped confessions. A four-point rating of topic IP measured the degree of potential threat per utterance. Cues discriminating true vs. false comprised word/phrase repeats, speech disfluency spikes, nonverbal overdone, and protracted headshaking. Non-lexical sounds discriminated true vs. false inthe reverse direction. Cues that distinguished IP only comprised speech speed, gesticulation amount, nonverbal animation level, soft weak vocal and “I (or we) just” qualifier. Adding “I don't know” to an answer discriminated both IP and true vs. false. The results supported hypothesis about differentiating deception cues from incriminating potential cues in high-stakes interviews, and suggested that extensive research on distinctions between stress-related cues and cues to deception would improve deception detection.  相似文献

This article reports initial findings from a study of middle grades educational reforms in Philadelphia. We use multilevel change models to analyze the impact on student mathematics achievement of privatization through the use of educational management organizations (EMOs), taking account of the structural reforms (creation of new K‐8 schools to replace selected middle schools) occurring simultaneously within the district. Overall, the longitudinal mathematics achievement gains for students in EMO‐managed schools were not larger than those for students in schools managed by the district. Non‐Edison EMO schools actually performed worse than district‐managed schools. With the exception of one older K‐8 school in one cohort, Edison schools did not significantly outperform district‐managed counterparts. Students in long‐established K‐8 schools generally outgained students in middle schools, but gains were not as large in newly‐established K‐8 schools. Across all types of schools, the second cohort of students obtained greater gains than did the first.  相似文献

This article presents the methods, findings, and implications of a participatory action research project that attempted to shed additional light on the debate over death with dignity (DWD) or physician-assisted suicide (PAS) legislation. In-depth, qualitative interviews with forty-five physically disabled residents of the San Francisco Bay Area, conducted by others with disabilities, revealed a wide breadth of opinions about and attitudes toward such legislation. For close to half of the participants, the desire for autonomy in making end-of-life decisions was a primary concern, yet fear that PAS legislation could violate this autonomy in various ways was a deep concern as well. Also reported were widespread accounts of disability-based discrimination and frequent expressions of fear about openly discussing positions that diverge from the official, publicly held opinions of disability leaders who oppose such legislation. The findings support those of a recent Harris poll demonstrating considerable diversity of opinion about PAS legislation among people with disabilities. The findings further suggest the need for additional research on the apparent disjunction between the diversity of attitudes held by those interviewed and the more unified position taken by many disability activists. Use of the study findings to promote greater dialogue within the community and to better position people with disabilities to take their place at the policy table also is discussed. In addition, the findings are seen as reinforcing the need for the public health community to become more engaged in this central ethical debate.  相似文献
