This paper discusses free online and Internet tools that can be adapted by librarians for use with library instruction and information literacy training, with a focus on social media and Web 2.0 technologies, including social networking websites Facebook and Twitter, blogs, RSS, wikis, and video sharing. Many students already use these technologies and are readily engaged with the library when the technologies are incorporated into library websites and classes. There are challenges in using these technologies, especially in countries with oppressive governments. This paper is based, in part, on a presentation the authors gave at the UNESCO Training the Trainers in Information Literacy Workshop at the Bibliotheca Alexandrina in Alexandria, Egypt in November 2008. 相似文献

Focusing on an environmental debate that took place in southeastern Louisiana, this study analyzes the experiences of several women who were identified as the debate's domestic, virtuous women: nurturing caretakers who entered public space to speak out as conservators of home and family. While acknowledging how powerful this public stance can be, this study also highlights the limitations of an identity that enables women to access political spheres traditionally closed to them but ultimately dismisses these voices when decisions about the environment must be made. 相似文献

Libraries are offering more services through social media Web sites like Twitter and Facebook, and this presence online is encouraging more conversation between libraries and patrons, including collection development requests. A review of popular Twitter and Facebook library profiles reveals the most successful accounts to be those where the library actively engages its users online. Through these media, libraries can have direct, immediate conversations with patrons that result in patron-initiated material requests. 相似文献

There is strong evidence that petrol-derived lead accumulates in the blood. That high doses of lead are very toxic has long been known, but the physical and mental effects of exposure to very low concentrations over a long period are still controversial. All governments are under strong pressure to restrict the permissible level of lead in petrol, but this poses problems for engine designers and entails penalties in oil conservation. 相似文献

AbstractTo fight homophobia in schools in Québec, many teachers rely on community organizations such as the Groupe de Recherche et d’Intervention Sociale (Research and Social Intervention Group) to address sexual diversity in class. This article documents major outcomes of these workshops as seen by students. Students identified topics related to sexuality and gender inversion as controversial, especially when involving men. The authors present how GRIS leaders decided to adapt intervention practices following such findings. 相似文献

Mineral dust can indirectly affect the climate by supplying bioavailable iron (Fe) to the ocean. Here, we present the records of dissolved Fe (DFe) and total Fe (TDFe) in North Greenland Eemian Ice Drilling (NEEM) ice core over the past 110 kyr BP. The Fe records are significantly negatively correlated with the carbon-dioxide (CO2) concentrations during cold periods. The results suggest that the changes in Fe fluxes over the past 110 kyr BP in the NEEM ice core are consistent with those in Chinese loess records because the mineral-dust distribution is controlled by the East Asian deserts. Furthermore, the variations in the dust input on a global scale are most likely driven by changes in solar radiation during the last glacial–interglacial cycle in response to Earth''s orbital cycles. In the last glacial–interglacial cycle, the DFe/TDFe ratios were higher during the warm periods (following the post-Industrial Revolution and during the Holocene and last interglacial period) than during the main cold period (i.e. the last glacial maximum (LGM)), indicating that the aeolian input of iron and the iron fertilization effect on the oceans have a non-linear relationship during different periods. Although the burning of biomass aerosols has released large amounts of DFe since the Industrial Revolution, no significant responses are observed in the DFe and TDFe variations during this period, indicating that severe anthropogenic contamination has no significant effect on the DFe (TDFe) release in the NEEM ice core. 相似文献
