Does ink age inside of a pen cartridge? 总被引:2,自引:0,他引:2
In questioned document examination and ink dating, it has been assumed that the ink inside of a pen cartridge does not begin aging until the ink is dispensed onto paper. Positive ion laser desorption (LD) mass spectra were obtained of ink-on-paper samples containing methyl violet, from new and old pens. Mass spectral studies with methyl violet have established the mechanism for how the dye degrades over time, and have provided structural information concerning the dye's degradation products. This information was used as an indication of the relative age of ink on paper. The LD mass spectrum of the ink from a new pen was indicative of "new" ink, whereas the spectra of the ink found in some older pens may appear to be either new or old. The ink from most of the old pens studied appears not to have aged, supporting the common assumption, whereas other ink samples produced "aged" ink spectra, suggesting otherwise. 相似文献

Despite its widespread use since the concept was introduced by David Truman (1951. The Governmental Process. New York: Alfred A. Knopf), counter-mobilization by organized interests has remained theoretically ambiguous and rarely studied empirically. We more fully develop the concept of short-term counter-mobilization, distinguish it from long-term counter-mobilization, specify the conditions under which we might observe short-term counter-mobilization, and test the resulting hypotheses with data on health care lobby registrations in the American states during the late 1990s. We find little evidence of short-term counter-mobilization among health interest organizations, which leads us to more fully consider several null hypotheses about the limits of strategic behavior on the part of organized interests.An earlier version of this paper was prepared for presentation at the Annual Meeting of the Midwest Political Science Association, Chicago, April 2004. This research was supported by a Robert Wood Johnson Foundation Investigator Award in Health Policy Research (ID#047727). 相似文献

Although a growing literature documents the benefits of industry–university research centers, most centers experience a significant amount of turnover among their industrial members. In order to gain a better understanding of this phenomenon, the current study attempts to identify factors that predict member renewal (DV). Questionnaire data were collected from industrial respondents (N=249) participating in 39 centers funded by the NSF IUCRC program. Structural, member benefits and administrative process variables were used to predict the dependent variable. Logistic regression analyses identified three significant predictors: professional networking benefits, research relevance and administrative operations. Implications of these findings for public policy, cooperative research management and future research are discussed. 相似文献

Battered women's reasons for staying with or leaving their male partners are varied and complex. Using data from the Domestic Violence Experience in Omaha, Nebraska, a discrete-time hazard model was employed to examine a woman's decision based on four factors: financial independence, witness of parental violence, psychological factors, and the police response to the domestic violence call. Findings regarding the first three factors are consistent with previous findings. However, a negative police response did not deter a woman from leaving, which is a different finding from previous studies. 相似文献

Regulatory studies assume that citizens can act as regulators to complement or correct failing state and market forms of regulation. Yet, there is a growing literature that shows that in reality citizens may fail to be effective regulators. This paper systematically analyses how power inequalities obstruct citizens in their regulatory roles. It compares four case studies with highly different social and political contexts but with similar outcomes of citizens failing to regulate risk. The case studies are analyzed by operationalizing sociological and political science ideas about manifestations of enabling and controlling forms of power in order to understand the way power inequalities obstruct citizens in their regulatory roles across diverse contexts. The article shows how citizens, from farmers and manual workers in both authoritarian developing and democratic developed contexts to even highly trained medical professionals from the US, have limited agency and are disempowered to act as regulators. Our analysis reveals that five patterns of disempowerment play a crucial role in obstructing successful society-based regulation: (i) dependency, (ii) capacity, (iii) social hierarchy, (iv) discursive framing, and (v) perverse effects of legal rights. 相似文献

AbstractHow can support organisations build the capacity of volunteer-driven non-governmental organisations (NGOs)? Citizen aid for relief and development has expanded rapidly in the twenty-first century, and the number of American aid organisations operating in the Global South has grown to nearly 10,000. These grassroots international NGOs – GINGOs – are small-budget, volunteer-driven organisations typically launched by Americans without professional experience in international development or nonprofit management. These groups prize the expressive and voluntaristic dimensions of development work, yet face challenges of amateurism, material scarcity, fragmentation, paternalism and restricted focus. We investigate whether support organisations, whose primary goals are to build the capacity of organisations and strengthen the organisational field, offer solutions to GINGOs’ inherent weaknesses. We draw on 15 semi-structured interviews with a stratified selection of support organisations, including associations tailored towards international development and towards nonprofit work at large. We find that support organisations offer resources to help GINGOs in managerial and administrative domains. Fewer support organisations help GINGOs build technical development skills, and fewer still push GINGOs to critically reflect on their role in development. We find that peer learning and online platforms could help engage GINGOs volunteers in networking spaces, even as their geographic dispersal in the US encourages their fragmentation and isolation. 相似文献
