Contexts of violent, intractable conflict such as those present in Israel, Nigeria, or Iraq represent times of severe crisis. Reducing the high indices of violence is very urgent, but the attempts of establishing peaceful arrangements in the short- or medium-term usually fail. Peace education, by contrast, is a long-term endeavor to resolve violent, intractable conflicts that aims at affecting moral stances that the conflicting parties take vis-à-vis each other. Unfortunately, however, peace education in times of severe crisis also faces many impediments. These impediments concern the agential, cultural, financial, and legal aspects of educative institutions within context of violent and intractable conflicts. Although these impediments strongly put into question the practice of peace education, this article shows that four reasons nevertheless strongly support this practice. These reasons refer to (1) humanity’s natural goodness, (2) the symbolic importance of peace education, (3) the peace-promoting experiences facilitated through peace education, and (4) peace education’s contribution to overcoming prejudices.  相似文献

Objective:We aimed to determine overlaps and optimal combination of multiple database retrieval and citation tracking for evidence synthesis, based on a previously conducted scoping review on facilitators and barriers to implementing nurse-led interventions in dementia care.Methods:In our 2019 scoping review, we performed a comprehensive literature search in eight databases (CENTRAL, CINAHL, Embase, Emcare, MEDLINE, Ovid Nursing Database, PsycINFO, and Web of Science Core Collection) and used citation tracking. We retrospectively analyzed the coverage and overlap of 10,527 retrieved studies published between 2015 and 2019. To analyze database overlap, we used cross tables and multiple correspondence analysis (MCA).Results:Of the retrieved studies, 6,944 were duplicates and 3,583 were unique references. Using our search strategies, considerable overlaps can be found in some databases, such as between MEDLINE and Web of Science Core Collection or between CINAHL, Emcare, and PsycINFO. Searching MEDLINE, CINAHL, and Web of Science Core Collection and using citation tracking were necessary to retrieve all included studies of our scoping review.Conclusions:Our results can contribute to enhancing future search practice related to database selection in dementia care research. However, due to limited generalizability, researchers and librarians should carefully choose databases based on the research question. More research on optimal database retrieval in dementia care research is required for the development of methodological standards.  相似文献

The UK Parliament passed the Freedom of Information Act (FOIA) in November 2000 after 3 years of government White Papers, consultation papers, and various Bills. The author served as special adviser to the House of Commons Select Committee on Public Administration which oversaw the Government proposals for legislation and the progress of the Bill into the House of Commons. The FOIA introduced pro-active publication of information via Publication Schemes, which were introduced on a staggered basis across the public sector and on January 1, 2005, rights of individual access were granted to individuals. The Act covers well over 100,000 public authorities in the UK and includes both Houses of Parliament. There is a power to add private bodies to the Act's coverage. The Act covers UK, English, Welsh, and Northern Irish public authorities. Scotland has its own FOIA which was enacted by the Scottish Parliament in 2002. The paper will examine the operation of the UK legislation and the role of the Information Commissioner and the Information Tribunal which deal with complaints of refusal and appeals respectively. The jurisprudence has been voluminous and now the English courts are beginning to hear appeals from the tribunal. The article will examine the major trends of the legislation and the problems presented by the legislation. The Government has already issued vetoes under the Act overriding the Commissioner's decision to grant access to the Cabinet papers relating to the Cabinet discussion on entering into war with Iraq and then on devolution of power to Scotland, Northern Ireland, and Wales. The decisions to open up the files on MPs expenses have caused one of the major constitutional crises in the UK in the last 75 years. As well as examining the way the Act has been interpreted, the author will essay some preliminary analyses of the impact of the Act on the realization of government objectives in passing the Act. The FOIA does sit alongside other legislation allowing access to personal files and access to environmental information and the whole information debate is set in the context of heightened sensitivity and secrecy in time of the war on terror and the state's increasing capacity to demand, store, and share information. The UK experience of the information debate will be examined.  相似文献
