Music as emotional self-regulation throughout adulthood
2010
Emotional self-regulation is acknowledged as one of the most important reasons for musical engagement at all ages. Yet there is little knowledge on how this self-regulatory use of music develops across the life span. A qualitative study was conducted to initially explore central processes and strategies of the emotional self-regulation during adulthood. The data were collected through group interviews and analyzed through qualitative content analysis. Participants were 21 interviewees with an age range of 21—70 years. The results clarified conceptual features of music-related emotional self-regulation in adulthood and revealed two main trends. First, the basic nature of regulation, includi…
Arbitraje para conflictos ambientales: una aproximación desde los Derechos Humanos
2020
En la confrontación entre la actividad empresarial y la protección del medio ambiente, pueden producirse daños sobre los derechos fundamentales. Desde una perspectiva de derechos humanos, el arbitraje puede desempeñar un rol importante como mecanismo que puede reducir las barreras de acceso a la justicia para las víctimas de estos conflictos y conseguir una reparación justa para ellas. El objetivo de este artículo es examinar cuáles deben ser los elementos para establecer un adecuado sistema de arbitrabilidad para la reparación del daño derivado de disputas medioambientales. Para ello, la autora se centra en las recientemente aprobadas Reglas de La Haya en Materia de Empresas y Derechos Hum…
Plant-herbivorous beetle networks : molecular characterization of trophic ecology within a threatened steppic environment
2015
DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…
Otto Neugebauer and the Göttingen Approach to History of the Exact Sciences
2018
Otto Neugebauer (1899–1990) was, for many, an enigmatic personality. Trained as a mathematician in Graz, Munich, and Gottingen, he had not yet completed his doctoral research when in 1924 Harald Bohr, brother of the famous physicist, invited him to Copenhagen to work together on Bohr’s new theory of almost periodic functions. Quite by chance, Bohr asked Neugebauer to write a review of T. Eric Peet’s recently published edition of the Rhind Papyrus (Neugebauer 1925). In the course of doing so, Neugebauer became utterly intrigued by Egyptian methods for calculating fractions as sums of unit fractions (e.g. 3/5 = 1/3 + 1/5 + 1/15). When he returned to Gottingen, he wrote his dissertation on thi…
Egg parasitoid attraction toward induced plant volatiles is disrupted by a non-host herbivore attacking above or belowground plant organs.
2014
Plants respond to insect oviposition by emission of oviposition-induced plant volatiles (OIPVs) which can recruit egg parasitoids of the attacking herbivore. To date, studies demonstrating egg parasitoid attraction to OIPVs have been carried out in tritrophic systems consisting of one species each of plant, herbivore host, and the associated egg parasitoid. Less attention has been given to plants experiencing multiple attacks by host and non-host herbivores that potentially could interfere with the recruitment of egg parasitoids as a result of modifications to the OIPV blend. Egg parasitoid attraction could also be influenced by the temporal dynamics of multiple infestations, when the same …
Binding analysis of Bacillus thuringiensis Cry1 proteins in the sugarcane borer, Diatraea saccharalis (Lepidoptera: Crambidae).
2015
Sugarcane borer (Diatraea saccharalis, F.) is an important corn pest in South America and United States. The aim of the present study was to analyze the susceptibility and binding interactions of three Cry1A proteins and Cry1Fa in a Brazilian D. saccharalis population. The results showed that Cry1Ab was the most active, followed by Cry1Ac, Cry1Fa and Cry1Aa. All Cry1-biotinylated proteins tested bound specifically to the D. saccharalis brush border membrane vesicles (BBMV). Heterologous competition assays showed shared binding sites for all Cry1A proteins and another one shared by Cry1Fa and Cry1Ab. Thus, pyramiding Cry1Aa/Cry1Ac and Cry1F proteins would be a recommended strategy for managi…
Exclusion of Saccharomyces kudriavzevii from a wine model system mediated by Saccharomyces cerevisiae.
2010
This study investigated the competition and potential hybrid generation between the species Saccharomyces cerevisiae and S. kudriavzevii in a wine-model environment. Our main goal was to understand why S. kudriavzevii has not been found in wine fermentations whilst their hybrids are present. Auxotrophic mutants (Ura(-) and Lys(-)) were used to favour the selection of hybrids and to specifically differentiate the two species in mixed fermentations carried out at different temperatures (17 °C, 24 °C and 31 °C). Both yeasts showed a reduction in their maximum specific growth rates in mixed fermentations, indicating a clear antagonistic effect between the two microorganisms. Temperature played …
How do novice teachers in Finland perceive their professional agency?
2015
This study investigated novice teachers’ perceptions of their professional agency during the initial years of their work in schools. The research questions were: (i) How do novice teachers perceive their professional agency within their work, and what do they see as the main restrictions and resources affecting that agency? (ii) How do novice teachers perceive their professional agency in the construction and renegotiation of their professional identities, and what do they see as the main restrictions and resources affecting their sense of agency? In theoretical terms, we adhere to a subject-centered sociocultural approach. This implies understanding subjects as active agents from a develop…
Psychology of Gender
2013
Throughout the history of philosophy authors have used claims about women’s deficient psychological capacities in order to justify their inferior position in society. Likewise, male and female defenders of women have most often based their arguments on claims about psychological equality, if not similarity, between the sexes. This chapter traces the major developments and shifts in philosophical discussions about gendered aspects of the soul from Antiquity until the Enlightenment.
Dioecious species and arbuscular mycorrhizal symbioses: the case of Antennaria dioica.
2013
Sex-specific interactions with herbivores and pollinators have been observed in female and male plants of dioecious species. However, only a limited number of studies have revised sex-specific patterns in mycorrhizal symbiosis. To test whether female and male plants of Antennaria dioica differ in their relationship with arbuscular mycorrhizal (AM) fungi, we examined the temporal and spatial variation in AM fungi in female, male and non-reproductive A. dioica plants in three natural populations in Finland during flowering and after seed production. Our results are consistent with previous studies both under greenhouse and field conditions with the same species showing differences in AM colon…
