Systematic review and synthesis methods have gained wide acceptance within the social sciences and, as a result, many postgraduate students now consider using them for their thesis or dissertation research. However, students are rarely aware of all the concrete implications that their decision entails. This reflective narrative reports the experience of a political science student who began to conduct a systematic review as part of his Ph.D. dissertation but who did not complete it. The aim of this article is to identify challenges and lessons learned from this experience and to formulate recommendations for postgraduate students who wish to make an informed choice with respect to the use of these methods. 相似文献
The rural landscapes surrounding large cities are rapidly becoming incorporated into the urban environment. The most conspicuous changes involve green spaces, such as former agro-forestry systems like fruit orchards. In this paper, we assess the influence on biodiversity of restoring a large urban traditional fruit orchard as reflected by six selected taxa: plants, lichens, butterflies, beetles, orthopteroids and birds. The study was performed in Prague, which is the capital city of the Czech Republic and has more than a million inhabitants. We studied the effect of orchard renewal in 45 patches (15 for birds and 30 for other taxa). The majority of taxa responded positively to the restoration. The restoration had a significant positive effect on the species richness of lichens, butterflies and beetles. All taxa showed significantly altered species compositions, and the number of red-listed species increased. Orchards have a high potential for multi-functional use. Orchards are productive agro-forestry systems and host numerous possible human activities. Therefore, orchard restoration also has a social aspect. Moreover, our research in this artificial ecosystem revealed that its restoration increased the biodiversity and conservation potential of the associated areas.
Ought we to take seriously large risks predicted by “exotic” or improbable theories? We routinely assess risks on the basis or either common sense, or some developed theoretical framework based on the best available scientific explanations. Recently, there has been a substantial increase of interest in the low‐probability “failure modes” of well‐established theories, which can involve global catastrophic risks. However, here I wish to discuss a partially antithetical situation: alternative, low‐probability (“small”) scientific theories predicting catastrophic outcomes with large probability. I argue that there is an important methodological issue (determining what counts as the best available explanation in cases where the theories involved describe possibilities of extremely destructive global catastrophes), which has been neglected thus far. There is no simple answer to the correct method for dealing with high‐probability high‐stakes risks following from low‐probability theories that still cannot be rejected outright, and much further work is required in this area. I further argue that cases like these are more numerous than usually assumed, for reasons including cognitive biases, sociological issues in science and the media image of science. If that is indeed so, it might lead to a greater weight of these cases in areas such as moral deliberation and policy making. 相似文献
AbstractDenial is considered to be the eighth and the final stage of genocide. Facing this issue, many European Union countries have opted to incriminate genocide denial. Furthermore, with the aim of harmonising national legislations, Framework Decision No. 2008/913/JHA was adopted in 2008, obliging the Member States to incriminate “publicly condoning, denying or grossly trivialising crimes of genocide, crimes against humanity and war crimes”. Genocide and other crimes denial is still present in Bosnia and Herzegovina, even though the rulings of the International Court of Justice, the International Criminal Tribunal for the former Yugoslavia, and the Court of Bosnia and Herzegovina, have shown that genocide was committed over Bosnian Muslims, in July 1995 in Srebrenica and its surrounding areas, as well as other numerous crimes against humanity and war crimes across entire Bosnia and Herzegovina. From 2007 there have been a number of attempts to incriminate genocide denial at the state level in Bosnia, but all of them were unsuccessful due to the opposition by representatives of Republika Srpska. Finally, in 2014, the genocide denial was incriminated in the Criminal Code of Federation of Bosnia and Herzegovina as an act of encouraging “national, racial and religious hatred, rift and intolerance”. 相似文献
ABSTRACTEducation is acknowledged as a component of transitional justice processes, yet details about how to implement education reform in postconflict societies are underexplored and politicized [King, Elisabeth. 2014. From Classrooms to Conflict in Rwanda. New York: Cambridge University Press]. Local and international actors often neglect the complicated nature of education reform in postconflict societies undergoing transitional justice processes [Jones, Briony. 2015. "Educating Citizens in Bosnia-Herzegovina: Experiences and Contradictions in Post-war Education Reform." In Transitional Justice and Reconciliation: Lessons from the Balkans, edited by Martina Fischer, and Olivera Simic, 193–208. New York: Routledge. Transitional Justice]. The role of the diaspora in transitional justice has been increasingly explored as a participatory transnational actor with influence and knowledge about local dynamics [Roht-Arriaza, Naomi. 2006. The Pinochet Effect: Transnational Justice in the Age of Human Rights. Philadelphia: University of Pennsylvania Press; Haider, Huma. 2008. “(Re)Imagining Coexistence: Striving for Sustainable Return, Reintegration and Reconciliation in Bosnia and Herzegovina. ”International Journal of Transitional Justice 3 (1): 91–113; Young, Laura, and Rosalyn Park. 2009.“ Engaging Diasporas in Truth Commissions: Lessons from the Liberia Truth and Reconciliation Commission Diaspora Project.” International Journal of Transitional Justice 3 (3): 341–361; Koinova, Maria, and D?eneta Karabegovi?. 2017.“ Diasporas and Transitional Justice: Transnational Activism from Local to Global Levels of Engagement.” Global Networks 17 (2): 212–233]. This article bridges academic literature about diaspora engagement and transitional justice, and education and transitional justice by incorporating the role of diaspora actors in post-conflict processes. Using empirical data from multi-sited field work in Bosnia and Herzegovina, Switzerland, Sweden, the United Kingdom, and France, it examines diaspora initiatives which aim to influence local transitional justice processes through translocal community involvement in education and youth policy. It argues that diaspora initiatives can provide alternative and intermediate solutions to the status quo in their homeland, with some potential for contributing to transitional justice and reconciliation processes. Ultimately, diaspora initiatives need support from homeland institutions in order to forward transitional justice agendas in post-conflict societies. 相似文献
ABSTRACTNew generalized binomial thinning operator with dependent counting series is introduced. An integer valued time series model with geometric marginals based on this thinning operator is constructed. Main features of the process are analyzed and determined. Estimation of the parameters are presented and some asymptotic properties of the obtained estimators are discussed. Behavior of the estimators is described through the numerical results. Also, model is applied on the real data set and compared to some relevant INAR(1) models. 相似文献
