Impact of the COVID-19 pandemic on young adults experiencing dual family life after high-conflict divorce

Objective: This paper describes the impact of the COVID-19 pandemic on the family lives of young adults whose parents had been through a high-conflict divorce and the extent to which these 18-to-30-year-olds believed the COVID-19 measures accommodated for their family situation. Background: Impact of the COVID-19 pandemic on family lives has been described in recent literature but no attention has been paid to young adults experiencing parental conflict due to a divorce transition impasse. Method: Data from 24 in-depth interviews were collected in the Belgian province of Limburg using a semi-structured interview guide with open questions and analysed via Nvivo. Results: Frequency of contact with parents decreased, contact with parents living abroad became nearly impossible. Different interpretations of and approaches to the rules led to frustration and quarrelling in families. The quality of the relationship with parents changed, often in a negative way. Respondents indicated that to their opinion due consideration had not been given to the situation of young adults with divorced parents. Conclusion: In order to adequately develop COVID-19 rules that are tailored to a wide range of families, with attention to the most vulnerable ones, we recommend that policy makers define a family by using a “feeling family paradigm” rather than defining a family in terms of a household and that they include a multi-actor and multi-disciplinary perspective in the decision-making processes

How to weight survey data with a dyadic multi-actor design?

This paper deals with adjustment for nonresponse in dyadic multi-actor survey designs. It presents a multi-dimensional approach to weighting that addresses the various analytical units represented in such data, so that sampling design weights are correctly accounted for and so that consistency between weights is achieved. This approach is demonstrated by using the primary respondents in the Divorce in Flanders study, which is a typical example of a dyadic multi-actor design. Five sets of weighting coefficients are made available whereby different subsets of data, according to different analytical units, are selected: the subset of the dyads, the subset of men and women respectively, and two subsets of marriages. Post-stratification – with the year of marriage, status of the reference marriage at the sampling date and five-year divorce cohort as auxiliary variables – was chosen as the weighting adjustment technique

The chemical ecology of herbivory on willows

Phenolic secondary compounds and trichomes are instrumental in the regulation of herbivory on Salicaceae. The roles of phenolics in willows as toxins or deterrents, as phagostimulants or ovipository signals, and as precursors in insect chemical defence are briefly reviewed. The interactions between salicaceous plants, herbivores and their predators are discussed in the context of theories on the evolution of interactions among three trophic level

Revisions of the afrotropical genera of argidae and species of Pampsilota konow, 1899 (Hymenoptera, Tenthredinoidea)

Open Access JournalThe Afrotropical fauna contains five genera of Argidae. These are keyed. New subjective synonyms, followed by the valid name in brackets, are Calarge Enslin, 1911 [Arge Schrank, 1802], Calarge africana Enslin, 1911 [Arge congrua Konow, 1907], Clyparge Pasteels, 1963 [Scobina Lepeletier & Serville, 1828], Clyparge terminalis Pasteels, 1963 [Scobina poecila (Klug, 1834)], and Sterictophora [sic] afra Pasteels, 1963 [Sphacophilus afer comb. n., species inquirenda near S. monjarasi Smith & Morales-Reyes, 2015]. The type material of both C. terminalis and S. afra was probably collected in the New World, but labelled with the wrong locality “Kamerun”. An introduction of both species to Africa, not followed by long-term establishment, seems less likely. The removal of these taxa from the faunal list of the region is recommended. The nine known Afrotropical species of Pampsilota are revised, and an illustrated dichotomous identification key presented, with distribution maps for all species. Four species are here described as new to science: P. dahomeyanus Goergen, Koch & Liston, sp. n., P. nigeriae Liston & Koch, sp. n., P. tsavoensis Liston & Koch, sp. n., and P. zebra Liston & Koch, sp. n. Lectotypes are designated for Pampsilota afer Konow, 1899, and Cipdele africana Mocsáry, 1909. The immature stages and host plant of only one species are known: P. dahomeyanus on Lannea nigritana (Anacardiaceae). Its larval morphology strongly resembles that of European and North American species of Arge. We provisionally retain Pampsilota as a valid genus, although it could justifiably be treated as comprising merely a species group, or groups, within Arge
