Honeybees prefer novel insect-pollinated flower shapes over bird-pollinated flower shapes
2019
AbstractPlant–pollinator interactions have a fundamental influence on flower evolution. Flower color signals are frequently tuned to the visual capabilities of important pollinators such as either bees or birds, but far less is known about whether flower shape influences the choices of pollinators. We tested European honeybee Apis mellifera preferences using novel achromatic (gray-scale) images of 12 insect-pollinated and 12 bird-pollinated native Australian flowers in Germany; thus, avoiding influences of color, odor, or prior experience. Independent bees were tested with a number of parameterized images specifically designed to assess preferences for size, shape, brightness, or the number…
Estrés y drogadicción: una perspectiva actualizada para 2020
2020
The role of stress in addiction is complex. In this editorial we highlight the main issues of interest in the ongoing research in relation to drug addiction and stress from an up-to-date perspective. Thus, taking into account that several bibliographic reviews have been published recently on the subject, the aim of this editorial has been to gather updated information in order to point out future directions of research that could make a valuable contribution to the knowledge about addictions and the role that stress plays in them. Finally, we stress the need for interdisciplinary research that addresses stress and addictions by incorporating and integrating physical and psychosocial facto…
Increased survival of honeybees in the laboratory after simultaneous exposure to low doses of pesticides and bacteria
2018
Recent studies of honeybees and bumblebees have examined combinatory effects of different stressors, as insect pollinators are naturally exposed to multiple stressors. At the same time the potential influences of simultaneously occurring agricultural agents on insect pollinator health remain largely unknown. Due to different farming methods, and the drift of applied agents and manure, pollinators are most probably exposed to insecticides but also bacteria from organic fertilizers at the same time. We orally exposed honeybee workers to sub-lethal doses of the insecticide thiacloprid and two strains of the bacterium Enterococcus faecalis, which can occur in manure from farming animals. Our re…
Ethnopharmacology of Love
2018
Background: Elixirs conferring eternal youth or inducing amatory and erotic attraction have been searched for without success. Lovesickness is a widespread affliction resulting from unrequited love and/or the impossibility for physical and emotional union. The symptoms are reflections of altered dopamine, serotonin, noradrenaline, testosterone and cortisol levels and range from frenzy and intrusive thinking to despair and depression, sharing traits with the neurochemistry of addiction and compulsive behavior disorder. Although it can seriously impact the quality of life, lovesickness is currently not considered in official disease classification systems. Consequently, no official therapeuti…
Functional Gustatory Role of Chemoreceptors in Drosophila Wings
2016
Summary: Neuroanatomical evidence argues for the presence of taste sensilla in Drosophila wings; however, the taste physiology of insect wings remains hypothetical, and a comprehensive link to mechanical functions, such as flight, wing flapping, and grooming, is lacking. Our data show that the sensilla of the Drosophila anterior wing margin respond to both sweet and bitter molecules through an increase in cytosolic Ca2+ levels. Conversely, genetically modified flies presenting a wing-specific reduction in chemosensory cells show severe defects in both wing taste signaling and the exploratory guidance associated with chemodetection. In Drosophila, the chemodetection machinery includes mechan…
The psychological, psychotherapeutic and medical dimensions of the activities of social services in Poland
2018
Abstract The article is an attempt to look at the issue of functioning of social services in Poland from an interdisciplinary perspective, presenting common areas of activity of professionals with socio-pedagogical affiliation with representatives of psychological, psychotherapeutic and medical environments. The considerations relate not only to the literature of the subject, but also to the research of the authors in this regard. The purpose of the presented reflection is also to indicate the areas of interdisciplinary scientific cooperation, including research. Its effect could be generating new research problems and solving them in the course of the work of interdisciplinary teams.

Physiotherapists’ conceptions of movement awareness– A phenomenographic study
2021
The phenomenon of movement awareness requires more attention to make it explicit in physiotherapy. The aim of this study was to explore the variation in physiotherapists’ conceptions of movement quality, focusing on movement awareness. The informants were 15 physiotherapists from a variety of physiotherapy fields. We collected data through two group interviews and used the phenomenographic method to analyze them. Four themes emerged from the data: 1) Being in contact with one’s own moving body; 2) Increased awareness of movement experiences; 3) Interrelationship between physiotherapist and patient; and 4) Better understanding of movement awareness. These themes varied by four descriptive ca…
Erfolgreiche Supervision in der Psychotherapieausbildung
2019
Zusammenfassung. Theoretischer Hintergrund: Supervision fand als Forschungsgegenstand in der Kognitiven Verhaltenstherapie vergleichsweise wenig Beachtung. Fragestellung: Ziel der explorativen Studie war es, Voraussetzungen und Auswirkungen erfolgreicher Supervision zu erheben. Methode: Elf Supervisor_innen und zehn Supervisand_innen des Weiterbildungsstudiengangs Psychologische Psychotherapie (Verhaltenstherapie) wurden mittels halbstrukturierter Leitfadeninterviews befragt. Die Auswertung erfolgte anhand der qualitativen Inhaltsanalyse nach Mayring. Ergebnisse: Es wurden Personenmerkmale (z. B. Kritikfähigkeit, Offenheit, Strukturiertheit), eine tragfähige Supervisionsbeziehung (z. B. ve…
Which Facets of Mindfulness Protect Individuals from the Negative Experiences of Obsessive Intrusive Thoughts?
2018
Obsessive intrusive thoughts (OITs) are experienced by the majority of the general population, and in their more extreme forms are characteristic of obsessive–compulsive disorder (OCD). These cognitions are said to exist on a continuum that includes differences in their frequency and associated distress. The key factors that contribute to an increased frequency and distress are how the individual appraises and responds to the OIT. Facets of mindfulness, such as nonjudgment and nonreactivity, offer an alternative approach to OITs than the negative appraisals and commonly utilised control strategies that often contribute to distress. Clarifying the role of facets of mindfulness in relation to…
