A brief Acceptance and Commitment Therapy intervention for depression : A randomized controlled trial with 3-year follow-up for the intervention group
2018
Abstract Objective This study examined the outcomes of a brief Acceptance and Commitment Therapy (ACT) intervention for depression delivered by novice therapists. Method Participants (N = 115) were randomized either to the brief (six sessions) ACT or to a waitlist control condition (WLC). Outcomes were assessed with diagnoses of depressive episodes (ICD-10) and questionnaires. Results After the 6-week intervention, diagnostic remission rates were 60% in the ACT and 22% in the control group. Further, 70% of the ACT participants were classified as either recovered or improved. The post-measurement between-group effect size for depression symptoms was large and favored the ACT group (BDI-II, d…
What happens after five years?: The long-term effects of a four-session Acceptance and Commitment Therapy delivered by student therapists for depress…
2017
Brief interventions can be viable treatment options worth consideration in addressing the growing need for treatments of subclinical and clinical depressive symptoms. However, there is uncertainty regarding the long-term benefits of these interventions. The aim was to examine the long-term (5-year) effects of a 4-session Acceptance and Commitment Therapy (ACT) intervention for low mood delivered by novice therapists in order to see whether lasting effects could be achieved cost-effectively with four intervention sessions. Originally, 57 self-referred clients were randomized into two groups: an intervention group and a waiting-list control group which received treatment later. The groups wer…
Long-term stability of early sudden gains in an acceptance and values-based intervention
2019
Though previous research has extensively reported that sudden gains are associated with superior treatment results, research on the long-term effects and stability of sudden gains is not as consistent. The current study explored the long-term stability of early sudden gains (ESGs) observed in a brief acceptance and values-based intervention for depression provided by novice therapists. The participants were 56 volunteers diagnosed with major depressive disorder. Among the participants, 23% experienced ESGs, i.e. they reached the status of improved or recovered in the Reliable Change Index (RCI; Jacobson & Truax, 1991) classification after only two sessions. The current study examined the le…
REVISION JAPANISCHER SPINNEN I.
1981
Nach der Untersuchung der in europaischen Museen aufbewahrten Typus-Sammlungen japanischer Spinnen wurden die folgenden Synonymien festgestellt: Theridion ferrumequinum BOSENBERG et STRAND, 1906 (Theridium meum BOSENBERG et STRAND, 1906, n. Syn.), Hypsosinga sanguinea (C.L. KOCH, 1845) (Theridium hilgendorfi KARSCH, 1879, n. Syn.) und Tetragnatha praedonia L. KOCH, 1878 (Tetragnatha nigrita niccensis STRAND, 1906, n. Syn.). Auserdem wurde erkannt, das die von LEHTINEN (1967) als Synonym des chinesischen Coelotes modestus SIMON, 1880, bezeichnete japanische Art Coelotes corasides (BOSENBERG et STRAND, 1906) eine selbstandige Art und von der chinesischen verschiedene Art ist.
Influence of aquatic microbiota on the survival in water of the human and eel pathogen Vibrio vulnificus serovar E
2004
Summary The eel and human pathogen Vibrio vulnificus serovar E (biotype 2) is seldom isolated from natural waters, although it can survive in sterilized artificial seawater microcosms for years. The main objective of the present study was to investigate whether aquatic microbiota can limit its survival and recovery from water samples. A set of preliminary experiments of survival in microcosms containing natural seawater and water from eel farms showed that the persistence of this pathogen was mainly controlled by grazing, and secondarily by bacterial competition. The bacte- rial competition was further analysed in artificial seawater microcosms co-inoculated with selected virulent serovar E…
Chemical Ecology of Egg Parasitoids Associated with True Bugs
2012
Parasitoids representing some 15 families of Hymenoptera develop in insect eggs; three of these families, Platygastridae (= Scelionidae), Mymaridae, and Encyrtidae, are associated with Heteroptera. Several species of heteropteran egg parasitoids are or may be important for biological pest control. Successful parasitism of insect herbivores by insect parasitoids arises through several phases of host searching, which lead female wasps to the vicinity of, or in contact with, their hosts. During the host location process, females encounter and explore a variety of stimuli, among which chemical cues (i.e., semiochemicals or infochemicals) play a pivotal role. Female parasitoids are under selecti…
Personality predicts social dominance in female zebra finches, Taeniopygia guttata, in a feeding context.
2011
6 pages; International audience; Although personality has been defined as a suite of correlated behaviours, most studies of animal personality actually consider correlations between a few traits. We examined the repeatability and correlational structure of five potential personality traits (activity, neophobia, exploratory tendencies, risk-taking behaviour and obstinacy), in female zebra finches. In addition, we assessed to what extent personality influenced social dominance in a feeding context in this gregarious species. All personality traits were found to be highly repeatable within individuals. In addition, except for obstinacy, all of them were related to each other, thus defining a b…

Sex-specific selection on energy metabolism - selection coefficients for winter survival
2010
Selection for different fitness optima between sexes is supposed to operate on several traits. As fitness-related traits are often energetically costly, selection should also act directly on the energetics of individuals. However, efforts to examine the relationship between fitness and components of the energy budget are surprisingly scarce. We investigated the effects of basal metabolic rate (BMR, the minimum energy required for basic life functions) and body condition on long-term survival (8 winter months) with manipulated densities in enclosed populations of bank voles (Myodes glareolus). Here, we show that survival selection on BMR was clearly sex-specific but density-independent. Both…
Preprinting is positively associated with early career researcher status in ecology and evolution.
2021
Abstract The usage of preprint servers in ecology and evolution is increasing, allowing research to be rapidly disseminated and available through open access at no cost. Early Career Researchers (ECRs) often have limited experience with the peer review process, which can be challenging when trying to build publication records and demonstrate research ability for funding opportunities, scholarships, grants, or faculty positions. ECRs face different challenges relative to researchers with permanent positions and established research programs. These challenges might also vary according to institution size and country, which are factors associated with the availability of funding for open acces…
