Metalmark moth larvae in the genus Brenthia (Lepidoptera: Choreutidae) live beneath gauzy web shelters spun over a leaf surface and chew an escape hole into the floor of their nests through which they dart when alarmed. We provide a video and data showing that these larvae, when their webs are disturbed, shoot through their wormhole to the opposite side of the leaf at extremely high speeds: the fa
Cases of mimicry provide many of the nature's most convincing examples of natural selection. Here we report evidence for a case of predator mimicry in which metalmark moths in the genus Brenthia mimic jumping spiders, one of their predators. In controlled trials, Brenthia had higher survival rates than other similarly sized moths in the presence of jumping spiders and jumping spiders responded to
Larvae and pupae of two Neotropical choreutids, Rhobonda gaurisana Walker and Zodia scintillana (walker) (Lepidoptera: Choreutidae), are described. Photographs, drawings, and scanning electron micrographs are provided for both species, and observations on larval behavior and biology are reported. The larval head in both genera is reinterpreted as being semiprognathous. The D2 setae on A9 arise fro
This article examines socioeconomic mobility across three generations in Sweden from 1815 and until 2011. Using longitudinal micro-level data from the Scanian Economic-Demographic Database (SEDD), we examine the transmission of socio-economic status along three different dimensions; social class (HISCLASS), occupational status (HISCAM), and earnings. We demonstrate an association between grandfath
Introduction: An impact of maternal obesity on ultrasound dating of pregnancy at 11–14 gestational weeks is possible and was investigated. Material and methods: A prospective cohort study based on the Danish national population during a 4-year period in which we entered all mothers with singleton pregnancies who had a known last menstrual period (LMP), a recorded booking of body mass index (BMI),
Purpose: To study the occurrence of severe visual impairment (SVI) and treatment outcome at 12 months in patients treated for wet age-related macular degeneration (AMD) by use of data from the Swedish Macula Register (SMR) and referrals to the regional low vision clinics in five northern counties. Methods: Referrals to low vision clinics during 2005, 2009 and 2013 and treatment outcome at 12 month
Background: The role of environmental exposures in the pathogenesis of ankylosing spondylitis (AS) remains unclear. In particular, two types of exposures have been suspected to play a role: mechanical stress and infections. The objective of this case-control study was to determine if childhood infections are associated with later development of AS. Methods: The cases with AS were identified throug
This study addresses the presence of religious difference in the Muslim-dominated cultural setting of Zanzibar, a context in which, in 2012, Christian minorities became targets in violent events directed against representations of the politically contested Union with Mainland Tanzania. As the attacked churches are primarily attended by people of non-island origins and the incidents were blamed on
Background: Shared decision-making is increasingly advocated in many countries. The aims of this study were to investigate whether patients receiving breast-conserving surgery at Skåne University Hospital Malmö, Sweden, perceived an offered possibility to join in the decision-making process regarding the surgical method; to identify potential determinants for not having perceived such an offer; an
This article deals with the Pentecostal Christianity and the relation to the other by looking at theological and practical responses on how Pentecostals deal with the world that generally is seen to be infused by evil. By first looking into some broad theological themes on how negotiate the social world in which Pentecostals reside, the theological base will be discussed against empirical material
Gunnar Ekelöf var en återkommande medarbetare i Grönköpings Veckoblad under slutet av 1940-talet och det tidiga 1950-talet. I sina alster i tidningen – flertalet publicerade under signaturen A:lfr-d V:stl-nd – ger han uttryck åt en hittills okänd sida av författarskapet. I inledningen diskuterar Daniel Möller, bokens redaktör, Ekelöfs motiv och avsikter med sina bidrag i veckobladet. Möller uppmär
Objective In patients with traumatic knee distorsion and hemarthrosis, to investigate the panorama of structural injury, as visualized on magnetic resonance imaging (MRI). Design Cohort study of 1145 consecutive patients with traumatic knee distorsion who underwent MRI within median 8 days after injury. We present structural injury as visualized on MRI in relation to age, sex and activity at injur
We respond to comments by Marsman, Ly, and Wagenmakers (2016) on Witte and Zenker (2016b).
The report presents the results of a review of the study methods related to vulnerable road user safety that are used today and aims to link accident causation factors to VRU accident risk. The review covered the following categories of study methods: epidemiological studies based on accident and injury data; in-depth accident investigations; naturalistic driving studies; behavioural observations;The report presents the results of a review of the study methods related to vulnerable road user safety that are used today and aims to link accident causation factors to VRU accident risk.
