Identification and Syntheses of Semiochemicals Affecting Mnesampela privata and Trioza apicalis
- 2009

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Autumn gum moth, Mnesampela privata (Lepidoptera: Geometridae) is an endemic Australian moth whose larvae feed upon species of Eucalyptus. The moths favorite host plants are E. globulus and E. nitens which are the most important species used in commercial plantations of the Australian pulpwood industry. The autumn gum moth has become one of the most significant outbreak insects of eucalyptus plantations throughout Australia. As a consequence great financial losses to the forest industry occur. Today insecticides such as pyrethroids are used for control of eucalyptus defoliators as M. privata. The carrot psyllid, Trioza apicalis (Homoptera: Psylloidea), is one of the major pests of carrot (Daucus carota) in northern Europe. The psyllid causes curling of the carrot leafs and reduction of plant growth. Today the carrot crops are protected with the pyrethroid insecticide cypermethrin, which is toxic to aquatic organisms and is, from 2010, prohibited for use in Sweden by the Swedish Chemicals Inspectorate. An alternative to insecticides is to protect the seedlings with semiochemicals, a chemical substance or mixture of them that carries a message. This thesis describes the identification and the syntheses of semiochemicals from the above mentioned insect species. From analysis of abdominal tip extracts of M. privata females from Tasmania a blend of (3Z,6Z,9Z)-3,6,9-nonadecatriene and (3Z,6Z,9Z)-3,6,9-heneicosatriene was identified as the sex pheromone of this species. The identification of the C19- and C21-trienes was confirmed by synthesis. In the analysis of carrot leaf extracts we found a compound, α-cis-bergamotene, that induces antennal response in the carrot psyllid. This is just the beginning of the studies of trying to manipulate this psyllid with semiochemicals instead of insecticides.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This aim of this study was to explore how hospital-based physicians in Sweden experienced the challenges in working conditions related to the provision of care during the initial response to the COVID-19 pandemic in 2020 when hospitals transitioned to pandemic care. Design/methodology/approach: The study has a qualitative design. Twenty-five hospital-based physicians were interviewed about their experiences from working in a hospital while healthcare organisations initially responded to COVID-19 pandemic in 2020. A thematic analysis was used to analyse the empirical material. Findings: The analysis resulted in four themes: involuntary self-management, a self-restrictive bureaucracy, passive occupational safety and health (OSH) management, and information overload. These themes reflect how the physicians perceived their work situation during the pandemic and how they tried to maintain quality care for their patients. Practical implications: The study gives valuable insights for formulating preparedness in regard to crisis management plans that can secure the provision of care for future emergencies in the healthcare services. Originality/value: This paper shows that a crisis management plans in the healthcare services should include decision structures and management, measures of risk assessment and OSH management, and the maintenance of personnel wellbeing. A prepared healthcare management can preserve quality care delivery while under crisis.

Bokkapitel (refereegranskat)abstract
- The world of accounting saw a revolutionary change in 2005 when the 2002 EUs decision to adopt International Financial Reporting Standards (IFRS) for quoted companies was implemented. Organisations in the financial sector were especially affected by the new principles-based accounting regime, which saw historical cost accounting downplayed in favour of a market-based valuation philosophy (i.e., fair values). Today, it is evident that IFRS, together with other kinds of regulations, both internationally and nationally, has made both the interpretation and implementation of accounting standards more difficult (for an overview, see Nilsson and Stockenstrand 2015).
