Three approaches to peace : a framework for describing and exploring varieties of peace
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- For decades, peace and conflict studies have devoted more attention to conflict than to peace, and despiteits centrality, peace itself has been under-conceptualized. In this paper, we propose a theoretical frameworkand methodologies to make peace beyond the absence of war researchable. The framework is designed to capture varieties of peace between and beyond dichotomous conceptions of positive versus negative peace, or successful versus failed peace processes. To capture the complexity of peace in its empirical diversity, our framework approaches peace in three different ways: as a situation or condition in a particular locality; as a web of relationships; and as ideas or discourses about what peace is or should be. These approaches provide different avenues for researching peace, and taken together they provide a fuller picture of what peace is, how it is manifested, experienced, and understood. We argue that this framework provides a way forward in advancing conceptual understandings and empirical analyses of peace that can facilitate systematic, comparative, qualitative analyses while at the same time accounting for the complex, multifaceted nature of peace.

Varieties of peace : presentation of a research program
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Varieties of Peace research program aims to analyze long-term effects of peace processes in conflicts that ended in the 1990s. The central research questions are: What characterizes peace after the peace processes initiated in the 1990s and how does it vary? How can this variation be described and explained? Peace processes have been studied using short time perspectives, usually in "lessons-learned" evaluations five years after conflict termination, and usually with theories of conflict as a starting point. The Varieties of Peace research program is an ambitious initiative, which starts from a theoretical understanding of peace, its quality and character, and views peace and peace processes as dynamic and transformative. It will investigate and evaluate different types of peace processes from a comparative perspective and 25–30 years after they started, with the ambition of producing generalizable knowledge about peace, what it is and how it can be achieved. As a starting point, the program studies explanatory factors in five areas: 1) the actions, capacity and resilience of civil society, 2) the interests and strategies of the elites, 3) the aims and character of the agreements, 4) the societies' institutions and resilience, and 5) international involvement. These issues will be studies in at least ten projects, with the ambition to capture and explain variation, internal dynamics and ultimately the results and effects of peace processes, studied over a longer period of time. The Varieties of Peace program is funded by Riksbankens Jubileumsfond: the Swedish Foundation for Humanities and Social Sciences, 2017-2024.

Tidskriftsartikel (refereegranskat)abstract
- Ethnopharmacological relevance: The emergence of multidrug-resistant strains of Mycobacterium tuberculosis underscores the need for continuous development of new and efficient methods to determine the susceptibility of isolates of Mycobacterium tuberculosis in the search for novel antimycobacterial agents. Natural products constitute an important source of new drugs, and design and implementation of antimycobacterial susceptibility testing methods are necessary to evaluate the different extracts and compounds. In this study we have explored the antimycobacterial properties of 50 ethanolic extracts from different parts of 46 selected medicinal plants traditionally used in Sudan to treat infectious diseases. Materials and methods: Plants were harvested and ethanolic extracts were prepared. For selected extracts, fractionation with hydrophilic and hydrophobic solvents was undertaken. A luminometry-based assay was used for determination of mycobacterial growth in broth cultures and inside primary human macrophages in the presence or absence of plant extracts and fractions of extracts. Cytotoxicity was also assessed for active fractions of plant extracts. Results: Of the tested extracts, three exhibited a significant inhibitory effect on an avirulent strain of Mycobacterium tubercluosis (H37Ra) at the initial screening doses (125 and 6.25 mu g/ml). These were bark and leaf extracts of Khaya senegalensis and the leaf extract of Rosmarinus officinalis L. Further fractions of these plant extracts were prepared with n-hexane, chloroform, ethyl acetate, n-butanol, ethanol and water, and the activity of these extracts was retained in hydrophobic fractions. Cytotoxicity assays revealed that the chloroform fraction of Khaya senegalensis bark was non-toxic to human monocyte-derived macrophages and other cell types at the concentrations used and hence, further analysis, including assessment of IC50 and intracellular activity was done with this fraction. Conclusion: These results encourage further investigations to identify the active compound(s) within the chloroform fraction of Khaya senegalensis bark. (C) 2014 Elsevier Ireland Ltd.

Balancing formal and informal success factors perceived by supply chain stakeholders : A study of woody biomass energy systems in Japan
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Small-scale woody biomass energy systems have an inherent ability to aid in emissions reduction while stimulating local economies and, as collective energy systems, are strongly connected to supply chain design based on local conditions and stakeholder integration. Despite an abundance of forest area alongside the promotion of biomass in energy policies, however, woody biomass utilization still remains low in Japan. The woody biomass supply chain, considered as a socio-technical system, involves a complex, cross-sectoral stakeholder network in which inter-organizational dynamics necessitates well-organized management based on an understanding of formal factors such as technology, as well as informal factors such as social relations and culture. In this paper, success factor perceptions from across the woody biomass supply chain are investigated based on semi-structured interviews with four stakeholders in the Kyushu region of Japan. Identified success factors here are: 1) respect of values & traditions, 2) transportation infrastructure, 3) business model integration, 4) relationship & trust, 5) local vitalization and 6) biomass quality control. A convergence as well as divergence of perceptions are observed, involving both formal and informal dimensions. Aiming to balance perceptions and to enable long-term success of woody biomass in Japan, a series of policy implications are drawn, including cross-ministerial integration, knowledge building on wood logistics, forest certification, local coordinators, biomass quality control standards and a feed-in-tariff for heat. This paper suggests a new arena of policy-making based on the importance of considering both informal and formal dimensions in energy policy.

The interbank market risk premium, central bank interventions, and measures of market liquidity
- 2014

Ingår i: Journal of International Money and Finance. - : Elsevier BV. - 0261-5606 .- 1873-0639. ; 48, s. 202-217

Tidskriftsartikel (refereegranskat)abstract
- When the interbank market risk premium soared during the financial crisis, it created a wedge between interest rates actually paid by private agents and the rapidly falling policy rates. Many central banks attempted to improve the situation by supplying liquidity to the domestic interbank market. This paper studies the Swedish interbank market risk premium using a unique data set on traded volume between banks and between banks and the Riksbank. We find that the main determinants of the Swedish interbank premium are international variables, such as US and EURO area risk premia. International exchange rate volatility and the EURO/USD deviations from CIP also matters, while standard measures of domestic market liquidity and domestic credit risk have insignificant effects. Nonlinear smooth transition (STR) models show that U.S. financial variables are more important in times of a rising U.S. risk premium. Our measure of actual turnover in the interbank market is associated with a significant reduction of the interbank market risk premium, as are credit provisions by the central bank.

Experimental and theoretical characterization of ordered MAX phases Mo2TiAlC2 and Mo2Ti2AlC3

Tidskriftsartikel (refereegranskat)abstract
- Herein, we report on the phase stabilities and crystal structures of two newly discovered ordered, quaternary MAX phases-Mo2TiAlC2 and Mo2Ti2AlC3-synthesized by mixing and heating different elemental powder mixtures of mMo:(3-m) Ti:1.1Al:2C with 1.5 less than= m less than= 2.2 and 2Mo: 2Ti:1.1Al:2.7C to 1600 degrees C for 4 h under Ar flow. In general, for m greater than= 2 an ordered 312 phase, (Mo2Ti) AlC2, was the majority phase; for mless than 2, an ordered 413 phase (Mo2Ti2)AlC3, was the major product. The actual chemistries determined from X-ray photoelectron spectroscopy (XPS) are Mo2TiAlC1.7 and Mo2Ti1.9Al0.9C2.5, respectively. High resolution scanning transmission microscopy, XPS and Rietveld analysis of powder X-ray diffraction confirmed the general ordered stacking sequence to be Mo-Ti-Mo-Al-Mo-Ti-Mo for Mo2TiAlC2 and Mo-Ti-Ti-Mo-Al-Mo-Ti-Ti-Mo for Mo2Ti2AlC3, with the carbon atoms occupying the octahedral sites between the transition metal layers. Consistent with the experimental results, the theoretical calculations clearly show that M layer ordering is mostly driven by the high penalty paid in energy by having the Mo atoms surrounded by C in a face-centered configuration, i.e., in the center of the Mn+1Xn blocks. At 331 GPa and 367 GPa, respectively, the Youngs moduli of the ordered Mo2TiAlC2 and Mo2Ti2AlC3 are predicted to be higher than those calculated for their ternary end members. Like most other MAX phases, because of the high density of states at the Fermi level, the resistivity measurement over 300 to 10K for both phases showed metallic behavior.

Deposition of MAX phase-containing thin films from a (Ti,Zr)(2)AlC compound target
- 2021
-
Ingår i: Applied Surface Science. - : Elsevier. - 0169-4332 .- 1873-5584. ; 551
-
Tidskriftsartikel (refereegranskat)abstract
- This work reports on sputter depositions carried out from a compound (Ti,Zr)(2)AlC target on Al2O3(0 0 0 1) substrates at temperatures ranging between 500 and 900 degrees C. Short deposition times yielded 30-40 nm-thick Al-containing (Ti,Zr)C films, whereas longer depositions yielded thicker films up to 90 nm which contained (Ti,Zr)C and intermetallics. At 900 degrees C, the longer depositions led to films that also consisted of solid solution MAX phases. Detailed transmission electron microscopy showed that both (Ti,Zr)(2)AlC and (Ti,Zr)(3)AlC2 solid solution MAX phases were formed. Moreover, this work discusses the growth mechanism of the thicker films, which started with the formation of the mixed (Ti,Zr)C carbide, followed by the nucleation and growth of aluminides, eventually leading to solid state diffusion of Al within the carbide, at the highest temperature (900 degrees C) to form the MAX phases.
