  • Miljöintegrering i praktisk tillämpning : En policystudie av två lokala stadsutvecklingsprocesser

    • Dealing with environmental problems has become one of the most challenging political issues of our time. Since the Brundtland report in 1987, environmental policy integration (EPI) that is, the mainstreaming of environmental issues in all policy sectors has emerged as a viable policy solution. This has meant that responsibility for implementing environmental policy rests to a large extent on local authorities where environmental problems with both local and global consequences are expected to be handled. However, there is still a disagreement on what EPI means in day-to-day decision making. With a theoretical framework drawing from theory on policy change, policy entrepreneurship and the neoinstitutional “logic of appropriateness” the aim of this dissertation is to analyze how the integration of environmental considerations manifests itself in local policy processes, highlighting what factors foster or hinder EPI. To reach this aim, I have followed two urban development processes in Kristianstad. This research offers insights on how EPI varies through the policy process and how focus is placed mainly on certain environmental issues and chiefly defined as of local importance. My study suggest that arenas for coordination are critical to overcoming the perceived “gap” between EPI on a strategic level and its implementation. This can help to clarify responsibility allocation among bureaucrats and their leeway for interpretation when new issues comes up continuously during the processes and affect the conditions for EPI. Furthermore, the dissertation gives insights on how acting “entrepreneurially” can enable an environmental issue to be included and given priority. This can also be a barrier if the ones acting entrepreneurially are not part of the entire process because the issue might receive less attention. In addition, if too much attention is given to one issue it might overshadow other environmental issues. Conversely, acting according to “the logic of appropriateness” can enable EPI by enhancing a more all-encompassing perspective on environmental considerations and also function as a cautious approach to radical change by preventing measures taken in absence of democratic legitimacy. By using the two theoretical perspectives, “entrepreneurial” and “appropriate” agency, this dissertation offers important insights into how different ways of acting interact and affect EPI and its outcome.

  • Silver-Triggered Activity of a Heterogeneous Palladium Catalyst in Oxidative Carbonylation Reactions
  • 2020
  • Ingår i: Angewandte Chemie International Edition. - : Wiley. - 1433-7851 .- 1521-3773. ; 59:26, s. 10391-10395
  • Tidskriftsartikel (refereegranskat)abstract
    • A silver-triggered heterogeneous Pd-catalyzed oxidative carbonylation has been developed. This heterogeneous process exhibits high efficiency and good recyclability, and was utilized for the one-pot construction of polycyclic compounds with multiple chiral centers. AgOTf was used to remove chloride ions in the heterogeneous catalyst Pd-AmP-CNC, thereby generating highly active Pd-II, which results in high efficiency of the heterogeneous catalytic system.

  • Highly Diastereoselective Palladium-Catalyzed Oxidative Cascade Carbonylative Carbocyclization of Enallenols
  • 2020
  • Ingår i: Organic Letters. - : American Chemical Society (ACS). - 1523-7060 .- 1523-7052. ; 22:2, s. 417-421
  • Tidskriftsartikel (refereegranskat)abstract
    • A palladium-catalyzed oxidative cascade carbonylative carbocyclization of enallenols was developed. Under mild reaction conditions, a range of cis-fused [5,5] bicyclic gamma-lactones and gamma-lactams with a 1,3-diene motif were obtained in good yields with high diastereoselectivity. The obtained lactone/lactam products are viable substrates for a stereoselective Diels-Alder reaction with N-phenylmaleimide, providing polycyclic compounds with increased molecular complexity.

  • Identification and synthesis of putative pheromone components of the threatened salt marsh bagworm moth, Whittleia retiella (Lepidoptera: Psychidae)
  • 2020
  • Ingår i: Journal of Chemical Ecology. - : Springer Science and Business Media LLC. - 0098-0331 .- 1573-1561. ; 46, s. 115-127
  • Tidskriftsartikel (refereegranskat)abstract
    • Whittleia retiella (Newman, 1847) is a threatened salt marsh species of the bagworm moth family Psychidae. For its preservation it is necessary to develop efficient tools to survey its distribution and habitat requirements in order to use appropriate conservation methods. Such tools may be pheromone-based monitoring systems, which have documented efficacy in establishing the occurrence of cryptic insect species in nature. By using gas chromatography combined with electroantennographic detection (GC-EAD), we found two compounds in female W. retiella headspace samples and whole-body extracts that elicited electrophysiological activity in male antennae. Gas chromatograpy coupled with mass spectrometry (GC-MS) operating in electron impact (EI) mode and comparison of the analytical data with those of synthetic reference compounds showed the chemical structures of these putative pheromone components to be (1S)-1-methylpropyl (5Z)-dec-5-enoate and 1-methylethyl (5Z)-dec-5-enoate. Field assays using baits loaded with synthetic compounds revealed that conspecific males were attracted to (1S)-1-methylpropyl (5Z)-dec-5-enoate alone or in combination with 1-methylethyl (5Z)-dec-5-enoate, whereas 1-methylethyl (5Z)-dec-5-enoate neither attracted nor repelled males in the field assays when tested alone. This study shows the potential of using (1S)-1-methylpropyl (5Z)-dec-5-enoate for monitoring W. retiella to gather more detailed information about the geographic distribution and habitat needs of this rare moth.
