The aim of this study was to develop chemical improvements to the original Weber protocol, in order to increase the intensity and time length of light emission and to eliminate false‐positive reactions. The intensity and duration of light were measured on serial blood dilutions using a plate reader chemiluminometer. Blood stains of various concentrations were impregnated in pure cellulose, dried, and luminol solution was added with/without the potential enhancers. An in silico study was also conducted, aiming to demonstrate the enhancing mechanism of hemoglobin denaturation using 8 M urea. The luminol blood detection test revealed important improvements after urea pretreatment or in the presence of monochloro‐triazinyl‐β‐cyclodextrin. This approach also eliminated the false‐positive reaction from sodium hypochlorite. These improvements could provide a higher sensitivity under particular circumstances such as old or washed blood stains, leading to a better localization for further DNA typing and higher quality photographic analysis. 相似文献

The Earth System Science Partnership, which unites all major global change research programmes, declared in 2001 an urgent
need to develop “strategies for Earth System management”. Yet what such strategies might be, how they could be developed,
and how effective, efficient and equitable such strategies would be, remains unspecified. It is apparent that the institutions,
organizations and mechanisms by which humans currently govern their relationship with the natural environment and global biochemical
systems are not only insufficient—they are also poorly understood. This article presents the science programme of the Earth
System Governance Project, a new 10-year global research effort endorsed by the International Human Dimensions Programme on
Global Environmental Change (IHDP). It outlines the concept of earth system governance as a challenge for the social sciences,
and it elaborates on the interlinked analytical problems and research questions of earth system governance as an object of
study. These analytical problems concern the overall architecture of earth system governance, agency beyond the state and
of the state, the adaptiveness of governance mechanisms and processes as well as their accountability and legitimacy, and
modes of allocation and access in earth system governance. The article also outlines four crosscutting research themes that
are crucial for the study of each analytical problem as well as for the integrated understanding of earth system governance:
the role of power, knowledge, norms and scale. 相似文献

Major depression ranges among the most frequently diagnosed psychiatric disorders. Accordingly, diagnoses of depression are often underlying insurance, compensation or disability claims. This report evaluates the validity of clinicians’ diagnoses of major depression in a sample of claimants. In 2015, n = 127 consecutive cases were examined for medicolegal assessment. For all of them, a diagnosis of major depression had been established by clinicians. All testees underwent a psychiatric interview, a physical examination, they answered questionnaires for depressive symptoms according to DSM-5, embitterment disorder, post concussion syndrome (PCS) and unspecific somatic complaints. Performance and symptom validity tests were administered. Only 31% fulfilled the diagnostic criteria for DSM-5 major depression according to self-report, while none did so according to psychiatric assessment. Negative response bias was found in 64% of cases, feigned neurologic symptoms in 22%. Symptom exaggeration was indiscriminate rather than depression-specific. By self-report, 64% of the participants qualified for embitterment disorder and 93% for PCS. In conclusion, clinicians’ diagnoses of depression seem often confounded by improper assessment of the diagnostic criteria, confusion of depression with bereavement or embitterment and also by response bias. 相似文献

This article analyses policy trends in Indonesian irrigation, particularly during the last five decades, from the perspective of dominant narratives, as authored, suggested and pushed by international donors. It argues that international donors' adherence to ‘deferred maintenance’ as the core element of irrigation policy problem framing does not match with farmers' and the irrigation agency staff perceptions and practices. The logic of obscuration and the discursive manoeuvers that maintain it are analysed. The article concludes that there is space for more profound conceptual contestation and for alternative actions pathways even within the ‘dominant paradigm’ to address management problems more effectively. 相似文献

The increased importance of ballot issue campaigns creates a need for communication and political science scholars to study the rhetorical strategies employed in such campaigns. This essay presents a typology of four communication functions employed in successful ballot issue campaigns: education, trust development, development of a positive message, and neutralization of the opposition. The typology is applied to an analysis of the 1986 campaign for liquor‐by‐the‐drink in Kansas. 相似文献

The argument is commonly made that television has changed the character of parliamentary elections. Its ever more central role in election campaigns outside the United States is held to have “presidentialized” parliamentary elections because it is a medium that projects personalities more effectively than ideas or policies. A comparison of the electoral roles of the Australian prime minister and the U.S. president indicates that both leaders are held personally accountable for government performance. However, such “presidentialism” appears to have little to do with television in Australia or in the United States. Television‐dependent citizens in both countries are less susceptible to the campaign appeals of chief executives than the rest of the voting public. Both leaders, but especially the president, do have an electoral impact. Counter to expectations, however, this impact makes itself felt in both cases among those voters who are not dependent on television for their political information and cues. Party identification seems to insulate the television‐dependent more successfully against leader effects. 相似文献
