All societies have to face the problem no one can financially support her- or himself during all periods of life. Low earnings capacity may be caused by, for example, sickness, disability, unemployment, child rearing, widowhood and old age. Thus, all societies have to organize support for those without earnings capacity. Three broad ways can be distinguished: the family, the market and the state.

Reflektionen i denna artikel påbörjade jag i ett anförande hållet i april 2019 vid tjugofemårsjubiléet av Teologiska Högskolan i Stockholm – min arbetsplats under många formativa år. Under hösten fick jag skäl att utveckla tankarna vidare då jag blev inbjuden att skriva i den bok som nu sett dagens ljus och vars syfte är att högtidlighålla hundraårsjubiléet av Vetenskapssocieteten i Lund – hemvist

Measurements of single neurone activity in the peripheral pheromone receptors of male Agrotis segetum (Denis and Schiffermuller) (Lepidoptera: Noctuidae) were performed in a wind tunnel using a portable electrophysiological recording unit. Filter paper and rubber septa loaded with synthetic sex pheromone, as well as individual conspecific female glands, were used as pheromone sources. Recordings,

Among the sex pheromone components of the turnip moth, Agrotis segetum, (Z)-5-decenyl acetate, (Z)-7-dodecenyl acetate and (Z)-9-tetradecenyl acetate are biosynthetically derived from palmitic acid by Δ11-desaturation, chain- shortening, reduction and acetylation. Females of a Zimbabwean population produce the three components in a 78:20:2 ratio, while Swedish females produce the three components

Species specificity of moth sex pheromones is in many cases achieved by means of specific blends rather than by specific components. Two pheromone strains of the European corn borer, Ostrinia nubilalis, use (E)- and (Z)-11-tetradecenyl acetate in different ratios as their pheromone, but show the same ratio of the pheromone precursors (70:30 E/Z-11-tetradecenoic acid). The hypothesis that the ratio

The major difference in pheromone production between the so-called E and Z strains of the European corn borer Ostrinia nubilalis is controlled by two alleles at a single autosomal locus. E-strain females produce an (E)-11- tetradecenyl acetate pheromone with 1-3% of the Z isomer, whereas Z-strain females produce the opposite blend. In laboratory-reared insects we found that F1 females produced, on

Extracts from different body parts of adult female Eriocrania cicatricella (Zett.) were tested for electrophysiological activity on conspecific male antennae. Extracts from the Vth abdominal segment, containing a pair of exocrine glands, elicited the largest electroantennographic response when compared to extracts of other body parts. Female extracts were analyzed by gas chromatography with simult

The noctuid sibling taxa Diachrysia chrysitis s. str. and D. tutti, of yet uncertain taxonomic status, have previously been shown to possess differences in morphology and to be attracted to different mixtures of the two presumed pheromone components (Z)-5-decenyl acetate and (Z)-7-decenyl acetate. Typical D. tutti males (clearly broken forewing marking) are known to respond to a 2: 100 mixture of

Extracts of different body parts of adult Trichoptera were tested for electrophysiological activity. Extracts of the IVth and Vth abdominal sternites of female Hydropsyche angustipennis, Rhyacophila nubila, and R. fasciata, containing a paired exocrine gland, elicited significant electroan-tennographic responses when tested on conspecific male antennae. The paired gland occurs also in males of all

Argues that there is no reason to dismiss species recognition as a possible cause of evolutionary change in moth sex pheromones. Selection for species recognition cannot explain all of the diversity in sex pheromones and the data supporting this contention are weak, but the alternative causes suggested, invoking mate choice between conspecifics as the mechanism of sexual selection, has no empirica

Sex pheromone communication in the nine European species of small ermine moths (Yponomeuta) is reviewed in regard to the potential role of pheromones in the speciation process. Six of the nine species studied (viz., Y. evonymellus, Y. cagnagellus, Y. padellus, Y. irrorellus, Y. plumbellus, and Y. vigintipunctatus) use a mixture of (E)-11-and (Z)-11-tetradecenyl acetate in different ratios as prima

Sex pheromone biosynthesis in the Asian corn borer Ostrinia furnacalis was studied by topical application of deuterium labelled fatty acids to the pheromone gland. The incorporation of the labelled acids into pheromone components and precursors was determined by gas chromatography with flame ionization detection and mass spectrometry in the selected ion monitoring mode. The labelling experiments s

(Z,Z,Z)-3,6,9-nonadecatriene (Z3, Z6, Z9-19Hy) and (Z,Z)-3,9-cis-6,7-epoxy-nonadecadiene (Z3, Z9-cis-6,7-epo-19Hy) were identified in pheromone gland extracts from female Erannis defoliaria. The two components were found in a 1:3 ratio, with the main component, Z3, Z9-cis-6,7-epo-19Hy present at an amount of about 1.5 ng per female. The components were identified by means of gas chromatography-mas

The paper focuses on analysis of macro‐ and micromorphological characteristics of relict slope deposits in Serra da Estrela (Portugal) to understand the significance of different slope processes and paleoenvironmental settings. Micromorphology is a useful sedimentology technique allowing significant advances compared to macroscopic techniques. Results show that different processes are involved in

Big Science is costly and complex, and historical evidence seems to suggest that projects often get delayed and more expensive than planned. On the basis of several studies of large infrastructures such as railroads and bridges, the Danish geographer Bent Flyvbjerg has proposed that there is an “iron law” of megaprojects, meaning that they almost without exception turn out more expensive and more

Patients with chronic pancreatitis have an impaired quality of life and are at risk for several long-term complications. It is important to diagnose and treat these patients to minimize the effects of the disease. Clinical manifestations of chronic pancreatitis include a wide range of symptoms and patients are managed differenth between medical centers. In recent years, there have been improvement
