Life cycle management (LCM) is a concept that goes beyond traditional corporate environmental management, due to its focus on a product’s entire life cycle. The spread of such concepts is usually understood in terms of processes of “diffusion,” whereby ideas spread over time by some inexplicable force. However, diffusion has proven less adequate to describe how ideas spreads in practice. Here, we address this oversight by studying the emergence and performance of what we refer to as life cycle practices. Drawing on an analysis of the development of a sustainability portfolio within a globally operating manufacturing company, we illustrate the kinds of life cycle work involved in dealing with local activities and interests, connecting activities and interests into action nets, performing life cycle practices, and spreading the life cycle idea. Finally, we discuss implications of life cycle work for research in the field of organization and management studies and for LCM research.

Over Time

Basing drug reimbursement on cost-effectiveness provides too little incentives for R&D. The reason for this is that cost-effectiveness is concerned with immediate value for money. But since the price of a drug usually declines over time, the drug might well provide value for money as seen over its entire life cycle, even though its price during patent protection is too high to warrant reimbursement according to the cost-effectiveness decision rule. We show in a theoretical model that welfare could be improved if decision-makers took a longer perspective and initially allowed higher prices than immediate value for money can motivate. We also discuss the real world relevance of applying dynamic cost-effectiveness.

Household Life Cycle

Abstract Poland is characterized by a relatively high level of homeowners (84% of population in 2018). The preference for ownership, as well as financial possibilities, are not balanced throughout the entire life cycle of a household. The scale of these differences, as well as the tendency to change over time, remains unknown. The subject of conducted research is to indicate how the structure of the tenure status of Poles changes over the life cycle of a household. This publication proposes the division of the household life cycle into the stages of formation, stabilization and reduction. The research on the structure of the tenure status of Poles was conducted for the period of 2006-2018. The analysis showed that, while the share of owner-occupiers increased significantly in Poland in the years 2006-2018, at the stage of forming a household rent begins to prevail. What is more, young people are more likely to choose market rent, and relocation to private housing is associated with having children or getting married. At the same time, there is no tendency to relocate to rented flats at the stage of household reduction in Poland.

Key Innovation

Methyl farnesoate (MF) plays hormonal regulatory roles in crustaceans. An epoxidated form of MF, known as juvenile hormone (JH), controls metamorphosis and stimulates reproduction in insects. To address the evolutionary significance of MF epoxidation, we generated mosquitoes completely lacking either of the two enzymes that catalyze the last steps of MF/JH biosynthesis and epoxidation, respectively: the JH acid methyltransferase (JHAMT) and the P450 epoxidase CYP15 (EPOX). jhamt−/− larvae lacking both MF and JH died at the onset of metamorphosis. Strikingly, epox−/− mutants, which synthesized MF but no JH, completed the entire life cycle. While epox−/− adults were fertile, the reproductive performance of both sexes was dramatically reduced. Our results suggest that although MF can substitute for the absence of JH in mosquitoes, it is with a significant fitness cost. We propose that MF can fulfill most roles of JH, but its epoxidation to JH was a key innovation providing insects with a reproductive advantage.

AbstractThis paper presents the logistic system of fuel life cycle, covering diesel oil and the mixture of rapeseed oil and butanol (2:3 ratio), using the Life-Cycle Assessment (LCA) method. This method is a technique in the field of management processes with a view to assessing the potential environmental hazards. Our intention was to compare the energy consumption needed to produce each of the test fuels and emissions of selected substances generated during ithe production process. The study involved 10,000 liters of diesel and the same amount of rapeseed oil and butanol mixture (2:3 ratio). On the basis of measurements the following results were obtained. To produce a functional unit of diesel oil (i.e. 10,000 liters) it is necessary to extract 58.8 m3 of crude oil. The entire life cycle covering the consumption of 10,000 liters of diesel consumes 475.668 GJ of energy and causes the emission to air of the following substances: 235.376 kg of COx, 944.921 kg of NOx, 83.287 kg of SOx. In the ease of a functional unit, to produce a mixture of rapeseed oil and butanol (2:3 ratio) 10,000 kg of rapeseed and 20,350 kg of straw should be used. The entire life cycle of 10,000 liters of a mixture of rapeseed oil and butyl alcohol (2:3 ratio) absorbs 370.616 GJ of energy, while emitting the following air pollutants: 105.14832 kg of COx, 920.03124 kg of NOx, 0.162 kg of SOx. Analysis of the results leads to the conclusion that it is oil refining which is the most energy-intensive and polluting process in the life cycle of diesel. The process consumes 41.4 GJ of energy, and causes a significant emission of sulfur oxides (50 kg). In the production of fuel that is a mixture of rapeseed oil and butyl alcohol (2:3 ratio), rape production is the most energy-intensive manufacturing process is (absorbs 53.856 GJ of energy). This is due to the long operation time of the farm tractor and combine harvester. The operation of these machines leads also to the emission of a significant amount of pollution in the form of COx (2.664 kg) and NOx (23.31 kg).

The induction of reproductive diapause of Nysius huttoni was studied in the laboratory at 20 1C and 60 10 RH under a series of photoperiod regimes 168 h 1410 h 1212 h and 1014 h lightdark Reproductive diapause was considered to have occurred if females failed to lay eggs for 50 days after emergence The sensitivity of different life stages to diapauseinducing photoperiods varied When newly emerged females whose immature stages had been reared at 168 h were transferred to 1014 h and 1212 h 467 and 793 of them entered reproductive diapause respectively However when fifth instar nymphs were transferred from 168 h to 1014 h and 1212 h 100 of adult females entered reproductive diapause If the entire life cycle was maintained at 1014 h and 1212 h 667 and 400 of females entered reproductive diapause respectively The critical photoperiod for reproductive diapause was estimated to lie between 1311 h and 135105 h
