文风会风改革的要害在于修党性、正学风、转作风

文风会风背后是一个学风、作风、党性问题。文风是学风的体现,是作风的折射。文风会风不正,假、大、空盛行,不仅官员本人失信于民,也影响党和政府的形象。我们的官员和政府以什么样的文风会风面对公众,既反映官员能力素质和对公众的态度问题,而且也是严肃的政治问题,它关系到群众对官员和政府作风的整体评价。     

我国非政府组织研究述评

随着党的十八届三中全会将"推进国家治理体系和治理能力现代化"确立为全面深化改革的总目标,学界对非政府组织掀起了新一轮的研究热潮。目前学界对国内非政府组织的宏观研究并不缺乏,但对其本土化理论思考与实证研究显见不足,仍然存在一定的局限性,在今后的研究中要注意对其加强角色定位、本土化研究和实证研究。     

Visualization of latent fingerprints using fluorescence lifetime imaging on paper emitting strong fluorescence

Latent fingerprints were successfully visualized using fluorescence lifetime imaging (FLIM) on paper which emits strong fluorescence with a lifetime close to that of fingerprints and thus from which it is difficult for time-resolved spectroscopy to visualize fingerprints. Latent fingerprint samples on paper were excited using a 450 nm or 532 nm nanosecond pulsed-laser, and time-resolved fluorescence images were obtained at a delay time of 6–16 ns in intervals of 1 ns, to the excitation pulse. The excitation beam was expanded using a lens, and the fluorescence from the fingerprints was captured using an intensified CCD camera. Because of the large fluorescence intensity of the background paper of approximately two to four orders of magnitude larger than that of the fingerprint, the fingerprint was not visualized on each fluorescence image by time-resolved spectroscopy. However, the fingerprint was visualized in a FLIM image constructed using a series of the fluorescence images for the case with the fluorescence intensity of the background paper being four orders of magnitude larger than that of the fingerprint. The difference in fluorescence lifetime in the FLIM image of the visualized fingerprint and background paper was in the order of 0.1 ns, which was an order of magnitude smaller than the inherent fluorescence lifetime of a few nanoseconds for the fingerprints and paper. It was demonstrated that, at a background fluorescence intensity with a certain order of magnitude larger than that of fingerprints, FLIM has the potential to visualize latent fingerprints which cannot be visualized by time-resolved spectroscopy.     

Cancer,HIV, and terrorism: translating public health models for prevention and control to counter-terrorism

What can cancer and HIV tell us about terrorism? How would we proceed if terrorism were a disease? A comparison of cancer and HIV can suggest alternative ways of conceptualizing terrorism and counter-terrorism using contrasting disease models that emphasize differing connections between etiology and prevention and control. A public health model also can help us think about terrorism as a basic research problem to be translated into therapeutic and preventive applications rather than primarily as a policy or political problem that makes only selective use of research studies. Through this re-conceptualization of terrorism as a basic and translational research challenge, we can draw upon the examples of the U.S. ‘War on Cancer’ and response to the ‘Aids Epidemic’ to help identify gaps in organizing academic and other resources to wage the ‘War on Terrorism.’ Recognizing and addressing these gaps could ultimately pave the way for more effective strategies in understanding and responding to the significant threats posed by terrorism, from the identification of factors that produce terrorist acts to the implementation of informed measures for the prevention and control of terrorist, and even proto-terrorist, activity.     

Beyond elections: perceptions of democracy in four Arab countries

This article draws on public opinion survey data from Morocco, Tunisia, Egypt, and Jordan to investigate first, whether a “demand for democracy” in the region exists; second, how to measure it; and third, how respondents understand it. The picture emerging from this analysis is complex, eluding the simple dichotomy between prima facie support and second order incongruence with democracy, which characterises current debates. Respondents have a more holistic understanding of democracy than is found in current scholarship or indeed pursued by Western or regional policymakers, valuing civil-political rights but prioritizing socio-economic rights. There is broad consensus behind principles of gender equality, but indirect questions reveal the continuing influence of conservative and patriarchal attitudes. Respondents value religion, but do not trust religious leaders or want them to meddle in elections or government. Moreover, while there is broad support for conventionally-understood pillars of liberal democracy (free elections, a parliamentary system), there is also a significant gap between those who support democracy as the best political system in principle and those who also believe it is actually suitable for their country.     

Development of Latent Fingerprints on Thermal Paper by the Controlled Application of Heat

Apparatus to produce a spatially and temporally uniform heat source is described and this is used to visualize latent fingerprints deposited onto thermal paper by raising the temperature of the paper. Results show an improvement over previous research when fingerprint deposits are aged or the developed fingerprints faint; visualization being enhanced by the use of a blue LED light source of 465 nm peak wavelength. An investigation of the components in fingerprint sweat likely to affect the solubility and hence color change of the dye present in the thermal paper has shown that polar protic solvents able to donate a proton are favored and a polar amino acid found commonly in eccrine fingerprint sweat (lysine) has been shown able to produce the desired color change. Aged fingerprint deposits on thermal paper from a variety of sources up to 4 years old have been visualized with this technique.

Women’s activism in a drug user union in the Downtown Eastside

Marginalized women in Canada who use criminalized drugs are often defined through institutional discourses of addiction, disease, poverty, sex work, and violence. Framed by many researchers as an at risk population, the fullness of these women’s lives is often rendered invisible, and the complexity, diversity, and range of experiences of their political and community work and their movement through the city are less often a topic of interest. This gap is addressed through an exploration of how some marginalized women come to know and experience themselves politically and physically, as part of a reflection upon their movement in and through the Downtown Eastside (DTES) of Vancouver, British Columbia, Canada. Drawing from community-based research in the DTES over a four-month period with women in leadership roles at the Vancouver Area Network of Drug Users, a drug user union, this paper highlights the results from focus groups and brainstorming sessions. The participants disrupt conventional notions of addiction and criminalization through their political and community activities and their ongoing resistance to systemic discrimination.     

Support and Opposition for Invading Iraq: Did the President's Speech Make a Difference?

Utilizing data from the annual San Antonio Survey, this research addresses the issue of support and opposition to invading Iraq among respondents randomly selected from Bexar County, Texas. Data were collected prior to and after President Bush addressed the nation on October 7, 2002, seeking broad citizen support for his plan, allowing us to ascertain whether or not his speech impacted the attitudes of potential voters. Our results indicate that the President's speech, along with the extensive media coverage about it, was effective in gaining support for his proposal to invade Iraq. A multivariate logistic regression analysis also displayed that the speech still had a significant impact even after controlling for confidence in the president, political orientation, race, ethnicity, nativity, and socio-demographic context. The findings suggest support for earlier research indicating that the impact of presidential speeches could boost the approval of a policy, in particular, if the speech occurred during his first term of office, was considered a “major” speech, was devoted to one important topic, and its primary focus was on foreign policy. Under these conditions, such a speech portrays the president as a strong leader.
