Classroom discussions: Possibilities and limitations for democratic classroom practices

2017

Are students offered possibilities to experience democratic practice in classrooms? Using an analysis of empirical data from classroom discussions in lower secondary school, this article identifies and explores two different types of classroom discussions which give students different positions: a conversation in which students are positioned as ‘poll respondents’, and a more deliberative conversation which positions students as learning debaters. The two forms of classroom discussions are discussed due to the way they give different meaning to democracy, and due to whether the student positions in the classrooms imply contribution to the subject matter and what is considered valuable knowl…

Enabling and constraining family: young women building their educational paths in Tanzania

2015

For an increasing number of African girls and women, upgrading the level of education has become a strategy for life improvement. This paper analyses the role that family plays in enabling women's education and contributes to understanding on the interconnectivity of education, work and family in women's lives in collective societies. The analysis focuses on how young Tanzanian women perceive the role of family and education in their ‘youth task’, of becoming adult. The analysis is based on interviews with seven young Tanzanian women enrolled in non-formal secondary education and nine professional women enrolled in higher education. The results show that the women were determined to pursue …

The hypothetical ancestral animal the Urmetazoa: Telomerase activity in sponges [Porifera]

2003

Sponges (Porifera) represent the lowest metazoan phylum, characterized by a pronounced plasticity in the determination of cell lineages, and they are the closest related taxon to the hypothetical ancestral animal, the Urmetazoa, from which the metazoan lineages diverged. In a first approach to elucidate the molecular mechanisms controlling the switch from the cell lineage with a putative indefinite growth capacity to senescent, somatic cells, the activity of the telomerase as an indicator for immortality has been determined. The studies were performed with the marine demosponges Suberites domuncula and Geodia cydonium, in vivo with tissue but also in vitro using the primmorph system. Primmo…

Chemical composition of the essential oil of Centaurea grinensis Reuter and Centaurea apiculata Ledeb: Growing wild in Croatia and Bulgaria, respecti…

2016

AbstractIn the present study, the chemical composition of the essential oils from aerial parts of Centaurea grinensis Reuter (K) collected at Žuta Lova, near Senj (Croatia), and aerial parts (L1) and flowers (L2) of C. apiculata Ledeb. collected near Rebro village, near Breznik town, Znepole Region (Bulgaria), both belonging to subgenus Lopholoma (Cass.) Dobrocz, was evaluated by GC and GC-MS. The main components of K were 4-vinyl guaiacol (21.5%), hexadecanoic acid (16.2%), acetophenone (12.5%). Caryophyllene oxide (15.8%) together with sphathulenol (14.5%) and humulene epoxide II (9.4%) were recognized as the main constituent of both the aerial part (L1) and flowers (L2) of C. apiculata. …

Miesjohtajien isyysdiskurssit

2019

Tämän tutkimuksen tavoitteena oli avata ja purkaa miesjohtajien isyydelle ja johtajuudelle antamia merkityksiä. Erityisen kiinnostuksen kohteena oli se, rakentavatko miesjohtajat isyyttään ja johtajuuttaan hyödyntäen perinteisiä ja dominoivia, jopa luonnollisiksi uskottuja totuuksia isyydestä ja johtajuudesta, vai ovatko isyyden ja johtajuuden merkitykset mahdollisesti muutoksessa. Miesjohtajien tutkiminen on tärkeää, koska johtajilla on vaikutusvaltaa organisaatioiden käytäntöihin niiden luojina ja hyväksyjinä. Tutkimuksen aineisto tuotettiin haastattelemalla 29 miesjohtajaa. Aineisto analysoitiin diskurssianalyysin keinoin. Tuloksena tulkittiin neljä isyysdiskurssia: ansaitsija-isyys -dis…

Holocene Spatiotemporal Redox Variations in the Southern Baltic Sea

2021

Low oxygen conditions in the modern Baltic Sea are exacerbated by human activities; however, anoxic conditions also prevailed naturally over the Holocene. Few studies have characterized the specific paleoredox conditions (manganous, ferruginous, euxinic) and their frequency in southern Baltic sub-basins during these ancient events. Here, we apply a suite of isotope systems (Fe, Mo, S) and associated elemental proxies (e.g., Fe speciation, Mn) to specifically define water column redox regimes through the Baltic Holocene in a sill-proximal to sill-distal transect (Lille Belt, Bornholm Basin, Landsort Deep) using samples collected during the Integrated Ocean Drilling Program Expedition 347. At…

On arithmetic sums of Ahlfors-regular sets

2021

Let $A,B \subset \mathbb{R}$ be closed Ahlfors-regular sets with dimensions $\dim_{\mathrm{H}} A =: \alpha$ and $\dim_{\mathrm{H}} B =: \beta$. I prove that $$\dim_{\mathrm{H}} [A + \theta B] \geq \alpha + \beta \cdot \tfrac{1 - \alpha}{2 - \alpha}$$ for all $\theta \in \mathbb{R} \, \setminus \, E$, where $\dim_{\mathrm{H}} E = 0$.

Parasite avoidance behaviours in aquatic environments

2018

Parasites, including macroparasites, protists, fungi, bacteria and viruses, can impose a heavy burden upon host animals. However, hosts are not without defences. One aspect of host defence, behavioural avoidance, has been studied in the terrestrial realm for over 50 years, but was first reported from the aquatic environment approximately 20 years ago. Evidence has mounted on the importance of parasite avoidance behaviours and it is increasingly apparent that there are core similarities in the function and benefit of this defence mechanism between terrestrial and aquatic systems. However, there are also stark differences driven by the unique biotic and abiotic characteristics of terrestrial …
