  • Garbage Collection for Prolog Based on WAM (Revised version)
  • 1986. - 1
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Warren Abstract Machine (WAM) has become a generally accepted standard Prolog implementation technique. Garbage collection is an important aspect in the implementation of any Prolog system. We first present a synopsis of the WAM and then show marking and compaction algorithms that take advantage of WAM's unique use of the data areas. Marking and compaction are performed on both the heap and the trail. The marking and compaction algorithms use pointer reversal techniques, which obviate the need for extra stack space. However, two bits for every pointer on the heap are reserved for the garbage collection algorithm. The algorithm can work on segments of the heap, which may lead to a significant reduction of the total garbage collection time. The time of the algorithms are linear in the size of the areas.

  • Suicide numbers during the first 9-15 months of the COVID-19 pandemic compared with pre-existing trends : An interrupted time series analysis in 33 countries
  • 2022
  • Ingår i: eClinicalMedicine. - : Elsevier. - 2589-5370. ; 51
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Predicted increases in suicide were not generally observed in the early months of the COVID-19 pandemic. However, the picture may be changing and patterns might vary across demographic groups. We aimed to provide a timely, granular picture of the pandemic's impact on suicides globally. Methods We identified suicide data from official public-sector sources for countries/areas-within-countries, searching websites and academic literature and contacting data custodians and authors as necessary. We sent our first data request on 22nd June 2021 and stopped collecting data on 31st October 2021. We used interrupted time series (ITS) analyses to model the association between the pandemic's emergence and total suicides and suicides by sex-, age-and sex-by-age in each country/area-within-country. We compared the observed and expected numbers of suicides in the pandemic's first nine and first 10-15 months and used meta-regression to explore sources of variation. Findings We sourced data from 33 countries (24 high-income, six upper-middle-income, three lower-middle-income; 25 with whole-country data, 12 with data for area(s)-within-the-country, four with both). There was no evidence of greater-than-expected numbers of suicides in the majority of countries/areas-within-countries in any analysis; more commonly, there was evidence of lower-than-expected numbers. Certain sex, age and sex-by-age groups stood out as potentially concerning, but these were not consistent across countries/areas-within-countries. In the meta-regression, different patterns were not explained by countries' COVID-19 mortality rate, stringency of public health response, economic support level, or presence of a national suicide prevention strategy. Nor were they explained by countries' income level, although the meta-regression only included data from high-income and upper-middle-income countries, and there were suggestions from the ITS analyses that lower-middle-income countries fared less well. Interpretation Although there are some countries/areas-within-countries where overall suicide numbers and numbers for certain sex- and age-based groups are greater-than-expected, these countries/areas-within-countries are in the minority. Any upward movement in suicide numbers in any place or group is concerning, and we need to remain alert to and respond to changes as the pandemic and its mental health and economic consequences continue.

  • God Rests in Rwanda : The Role of Religion in the 1994 Genocide in Rwanda
  • 2019
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This study analyses the role of religion in the Rwandan genocide, providing new explanations to the complex dynamics of devaluation and victimisation processes in genocidal violence. The thesis explains how religion was used in different contexts prior to, during, and after the 1994 genocide. The following questions guide this study: What kinds of religious concepts and arguments were used in the context of the Rwandan genocide, and how? Why were they used and what did these concepts and arguments mean? Finally, did the meanings of the religious arguments change over time and between different contexts, and if so why?Texts from three sources were analysed: the Hutu extremist propaganda in Kangura magazine and in RTLM broadcasts, and testimonies from the ICTR trials. The analysis was guided by Roger Dale Petersen’s theory on Fear, Hatred, and Resentment, as well as theories on devaluation, social identity, self-victimisation, and competitive victimhood. This thesis utilises the computer software MAXQDA to search for concepts and arguments, which are analysed through the contextual approach developed by Quentin Skinner.   This thesis demonstrates that the Hutu propagandists used religious mythology to argue that the Tutsis were not of Rwandan origin and therefore had no rights in Rwanda. The devaluation of the Tutsi was not only or even primarily done through downgrading animalistic epithets, but through the elevation of Tutsis with emphasis on the historical, and allegedly divine, superiority of the Tutsi. This devaluation allowed the Hutu extremists to claim victimhood, a necessary conviction to argue that violence committed by the Hutus were acts of self-defence. In the deeply Christian context of Rwanda, the extremist Hutu propagandists constructed a Hutu God, while claiming that the Tutsis were non-Christian, irreligious, or atheists, in order to create different religious identities for the two groups.This study also assesses the judicial aftermath, and argues that religious concepts were used in similar ways in ICTR testimonies to claim innocence, credibility, and victimhood. This thesis thus sheds new light on the importance of religious belief systems in genocidal violence, highlighting the crucial role of religion prior to, during, and after the genocide in Rwanda.
