Abundant life : holistic soteriology as motivation for socio-political engagement
- 2020
-
In: The Routledge Handbook of African Theology. - 9781138092303 - 9781315107561
-
Book chapter (peer-reviewed)abstract
- In a world plagued by terrorism and global catastrophes, when the news media is often filled with reports of wars and human suffering—where does the Christian Church stand? What does it mean to preach salvation in a world of such widespread tragedy? In what way can Christian theology contribute to an increased involvement for justice, peace, and sustainable living? For me as a Pentecostal theologian, 2 daughter of Swedish Pentecostal missionaries, raised in Rwanda, and deeply affected by the horrors of ethnic cleansing that occurred in the country, the question of salvation and its relation to good and evil, society and justice has become central to my theological thinking. In this chapter, I will propose a holistic model for understanding salvation as “abundant life” (John 10:10) and suggest that such a model would promote our involvement—as Christians and Pentecostals—in societal reform. To reach that conclusion, I will present insights and examples from the Swedish Pentecostal movement, African Pentecostal theology, and Latin American liberation theology from the 1960s. Finally, the argument ends with an effort to portray Jesus, the Savior Himself, the King of Peace, He who is Life and gives life.

Counter-Interrogation Strategies when Anticipating Questions on Intentions
- 2013
-
In: Journal of Investigative Psychology and Offender Profiling. - : Wiley. - 1544-4759. ; 10:1, s. 125-138
-
Journal article (peer-reviewed)abstract
- The present experimental study adds to the emerging line of psycholegal research focusing on true and false intentions. It is the first to examine mock suspects’ (N = 120) counterinterrogation strategies in investigative interviews in which they anticipate questions on their intentions. As planning is an inherent part of many intentions, mock suspects were, in addition to questions on their intentions, asked a set of questions that pertained to the planning phase in which they formed their intentions. Besides ratings of the anticipation and difficulty of the questions, participants were asked to provide their principal strategy for being perceived as truthful. Both truth tellers and liars perceived the questions on the planning phase as significantly more unanticipated than the questions on their intentions. Furthermore, liars perceived the questions on the planning phase as more difficult to answer than did truth tellers. Liars and truth tellers differed with respect to their principal strategy employed for being perceived as truthful. Liars’ most commonly used strategy was to stick to the cover story, whereas truth tellers’ most common strategy was to be honest. The results are discussed in relation to the unanticipated questions approach and psychological concepts such as the illusion of transparency.

Past abrupt changes, tipping points and cascading impacts in the Earth system
- 2021
-
In: Nature Geoscience. - : Springer Science and Business Media LLC. - 1752-0894 .- 1752-0908. ; 14:8, s. 550-558
-
Research review (peer-reviewed)abstract
- A synthesis of intervals of rapid climatic change evident in the geological record reveals some of the Earth system processes and tipping points that could lead to similar events in the future. The geological record shows that abrupt changes in the Earth system can occur on timescales short enough to challenge the capacity of human societies to adapt to environmental pressures. In many cases, abrupt changes arise from slow changes in one component of the Earth system that eventually pass a critical threshold, or tipping point, after which impacts cascade through coupled climate-ecological-social systems. The chance of detecting abrupt changes and tipping points increases with the length of observations. The geological record provides the only long-term information we have on the conditions and processes that can drive physical, ecological and social systems into new states or organizational structures that may be irreversible within human time frames. Here, we use well-documented abrupt changes of the past 30 kyr to illustrate how their impacts cascade through the Earth system. We review useful indicators of upcoming abrupt changes, or early warning signals, and provide a perspective on the contributions of palaeoclimate science to the understanding of abrupt changes in the Earth system.

A Retrospective Analysis of Early and Immediately Loaded Osseotite Implants in Cross-Arch Rehabilitations in Edentulous Maxillas and Mandibles Up to 7 Years
- 2013
-
In: Clinical Implant Dentistry and Related Research. - : John Wiley & Sons. - 1523-0899 .- 1708-8208. ; 15:3, s. 380-389
-
Journal article (peer-reviewed)abstract
- Background: Immediate loading of full-arch restorations yields good results in selected cases, but long-term follow-up and the outcome in compromised bone are scarcely evaluated. Purpose: To evaluate immediately loaded Osseotite implants (Biomet 3i, Palm Beach, FL, USA) installed in healed or grafted bone, with regard to implant survival and peri-implant bone loss up to 7 years in function. Materials and Methods: Information was retrospectively retrieved from 83 patients' records with 749 Osseotite implants supporting immediately loaded semipermanent full-arch acrylic restorations. Five hundred sixty-eight (75.8%) implants were placed in healed bone and 181 (24.2%) in augmented bone, regenerated with sinus lifting and/or onlay/inlay grafts with/without biomaterials and membranes. Implant survival and success based on radiological peri-implant bone loss were registered. Wilcoxon rank sum tests evaluated peri-implant bone loss in compromised versus healed bone or between jaws or time intervals with p < .05 as statistically significant. Results: Sixteen of 749 implants failed (2.1%), 11/343 in maxilla (3.2%) and 5/406 (1.2%) in mandible. After 7 years, the cumulative failure rate was 9%. Mean peri-implant bone loss increased to 1.2 mm (SD 1.0) during the first 2 years but remained unchanged thereafter. Around implants in grafted bone, on average, 0.3 mm more bone loss was found. Conclusion: The Osseotite implants offer a predictable long-term outcome in terms of implant survival and stable peri-implant bone under immediate loading even in grafted bone. However, the high incidence of technical repair because of fractures of the semipermanent provisionals requires attention because it may be negative from a cost-benefit perspective. Implants in grafted bone show a tendency to a more pronounced initial bone remodeling without clinical consequence in the long term.

Antiviral Properties of Oxidized Silicon Nitride Against SARS-CoV-2
-
Other publication (other academic/artistic)abstract
- The spread of SARS-CoV-2 led to a global pandemic that caused several million deaths. The severity of this pandemic created challenges for scientists worldwide regarding the prevention of the spread of COVID-19, the disease the virus causes. While the use of personal protective equipment and social distancing limited the spread of the virus, high transmission rates were noted. A solution to the issue of viral spread can be partially given by the utilization of antiviral materials for long-term protection against pathogens on environmental surfaces. To this end, nitrides are materials of high interest due to their proven efficiency in inactivating bacteria and viruses. Silicon nitride (Si3N4) is a ceramic material that possesses an inactivation mechanism termed ‘catch and kill’. In this study we hypothesized that a surface-modified Si3N4 material whose hydrophilicity has been increased through a heat treatment could lead to high attachment and inactivation of SARS-CoV-2 virions. Si3N4 powders were oxidized, characterized and the inactivation of SARS-CoV-2 by them was tested. The results showed that oxidized Si3N4 was highly effective in binding and inactivating SARS-CoV-2 after as little as one minute of contact and can be used to inhibit the spread of COVID-19 under certain circumstances.

Comparative study on different industrial oxidic by-products as neutralising agent in bioleaching
- 2008
-
Licentiate thesis (other academic/artistic)abstract
- A comparative study on bioleaching of a pyrite concentrate using ten different industrial oxidic by-products as neutralising agent has been performed with a commercial grade slaked lime chemical serving as reference material. The acid produced during oxidation of pyrite was neutralised by regular additions of neutralising agent whenever needed to maintain a pH of 1.5. Bioleaching was conducted as batch experiments in 1-L scale reactors, with a mixed mesophilic culture at a temperature of 35º C. The different industrial oxidic by-products used were steel slag, ashes, dust and lime sludge. The aim of the study was to investigate the possibility to replace normally used lime or limestone with oxidic by-products, considering their neutralising capacities and possible negative impact on the bacterial activity. The bioleaching efficiency was found to be equally good or better, when by-products were used for neutralisation instead of slaked lime, and the bioleaching yields of pyrite were in the range 69-80%, except the Waste ash, which had a leaching yield of 59%. Some of the by-products used contained potentially toxic elements for the bacteria, like fluoride, chromium and vanadium, but no negative effect of these elements could be observed on the bacterial activity. The Waste ash contained a large number potentially toxic elements and a high chloride concentration of 11%, which had a negative effect as observed on the lower redox potential and leaching yield. Slags originating from stainless steel production should be avoided for environmental reasons, due to the presence of chromium. The electric arc furnace (EAF) dust has a good potential to be used as neutralising agent in bioleaching processes for zinc recovery from zinc sulphides, due to the high content of zinc, however the chlorides present should be removed prior to its use. The neutralising capacity, as determined by the amount needed for neutralisation during bioleaching, were rather high for all the steel slags, EAF dust, Bioash and Mesalime with a range of 16-37 g as compared with 22 g needed for slaked lime. However, Waste ash and Coal & Tyres ash had lower neutralising capacities with 81 g and 57 g needed, respectively. Hence, it is concluded that considerable savings in operational costs can be obtained by replacement of lime or limestone with steel slag, ash, dust or sludge without negative impact on bioleaching efficiency. Use of industrial oxidic by-products would provide opportunities to recycle elements present in them as for example zinc rendering an eco-friendly process and a means for sustainable use of natural resources.
