Temperamentally inhibited children are at risk for poorer maths performance : self-concept as mediator
2020
AbstractIt has repeatedly been found that temperamental inhibition and low academic achievement are associated with each other: children with cautious and wary or shy behaviour are at risk for low academic achievement. Several suggestions about the mechanism behind this association have been made, these highlighting for example, the fewer learning opportunities of cautious and wary children and more negative interaction between teachers and inhibited children. However, the empirical studies about these mechanisms are rare and, thus, they have remained unclear. This study examined whether children’s maths-related self-concept of ability acts as a mediator between their temperamental inhibiti…
Direct C-H metalation with chromium(ii) and iron(ii): transition- metal host/benzenediide guest magnetic inverse-crown complexes
2009
Check M(etal)ate: The chessboard and the figures represent a special reaction in which different low-polarity metals can metalate arenes directly when they are brought into the right position. In a combination of queen (sodium) and knight (chromium or iron), it is possible for the knight (usually the weaker piece) to make a direct deadly hit on the king (benzene) in this game of elemental chess.

Intraspecific variation in mating behaviour does not cause sexual isolation between Drosophila virilis strains
2005
There is increasing evidence that mate recognition systems vary within species. We studied the courtship rituals of five Drosophila virilis strains to investigate this intraspecific variation. Males that actively and persistently courted the female without paying much attention to the female's behaviour were the most successful at copulating. Intraspecific variation in mating rituals was high, but not as high as at the species level and it was not high enough to cause sexual isolation between the strains. The differences in courtship interactions of the strains reflected their geographical origin. Males from one of the strains did not produce audible song during their courtship, but still m…
Courtship song and immune function in the field cricket Gryllus bimaculatus
2003
It has been assumed that sexual ornaments have evolved to reveal males’ health and vigour for females. Choosy females may indirectly use ornaments as an indicator of the presence and effectiveness of genes for resistance against parasites. In this study we tested whether females of the Mediterranean field cricket, Gryllus bimaculatus, can use courtship song as a cue for choosing males with high immunocompetence, measured as encapsulation rate of nylon implants and lytic activity of haemolymph. We found that female crickets preferred courtship songs from males with a high encapsulation rate. Female crickets also had a tendency to prefer courtship songs with high tick rate and long high-frequ…
Increasing intensity of deimatic behaviour in response to repeated simulated attacks: a case study on the mountain katydid (Acripeza reticulata)
2022
Abstract How and when deimatic behaviours are performed can change during encounters between predators and prey. Some predators attack repeatedly, investigating and manipulating prey, and in response, an individual’s deimatic behaviour may intensify or may diminish in favour of escaping. The presence of a resource can further force a trade-off between displaying and escaping. Here, we examined the intensity of the katydid’s deimatic behaviour, a visual display, the propensity of their escape response under repeated simulated attacks, and how these responses change in the presence of foraging resources. We found that display intensity increased with repeated simulated attacks and that femal…
Home Oral Care Domiciliary Protocol for the Management of Dental Erosion in Rugby Players: A Randomized Clinical Trial
2022
People performing regular physical activity are at high risk of dental erosion especially in cases of high sport drinks intake. Biomimetic hydroxyapatite-based oral hygiene products, like toothpastes and mouthwashes, have been investigated in recent years for their remineralizing activity on the teeth. The aim of the present study was to evaluate the efficacy of two different oral hygiene protocols, respectively consisting of the combination of a hydroxyapatite-based toothpaste plus mouthwash (Trial group) or toothpaste alone (Control Group). At baseline (T0), as well as at 15 days (T1), 30 days (T2) and 90 days (T3), the following clinical indexes were assessed: Basic Erosive Wear Examinat…
Les auteures absentes dans les manuels de clase: des propositions pour leur inclusion
2014
El presente trabajo es consecuencia de la investigación de la Universitat de València que analizó la presencia de las mujeres en los contenidos de todas las asignaturas de la ESO en tres editoriales distintas. Se revisaron 109 manuales y los resultados que se obtuvieron fueron desastrosos: solo un 7,6 % de los personajes citados eran mujeres (López-Navajas, 2014). En el presente trabajo se ejemplifica con dos relevantes dramaturgas, las propuestas didácticas que se están desarrollando en el marco del proyecto Las mujeres en la ESO. Estas podrían convertirse, además, en un vehículo adecuado para dar a conocer en las aulas un mayor número de voces femeninas. The purpose of this paper is to ca…
Towards therapeutic gene delivery to human cancer cells : targeting and entry of baculovirus
2008
Geeniterapia on yksi tulevaisuuden hoitomuodoista taistelussa syöpää vastaan. Virukset ovat evoluution myötä kehittyneet tehokkaiksi geeninsiirtäjiksi ja ovat nykyään käytetyimpiä geeninsiirtovektoreita. Yksi geenihoitojen yleistymisen esteistä on kuitenkin ollut virusvektoreiden puutteellinen kohdennus haluttuun kudokseen. Kohdentaminen on erityisen tärkeää syövän hoidossa, jotta hoito vaikuttaisi pääasiassa pahanlaatuisiin soluihin.Mäkelä kehitti tutkimuksessaan syöpäsoluihin kohdentuvia bakulovirusperäisiä geeninsiirtovektoreita. Hän tutki myös viruksen sisäänmenomekanismeja ja kulkeutumista kohdesoluissa.- Hyönteisiä infektoiva bakulovirus on luontaisesti vaaraton ihmisille. Se on helpo…
Network Capacity Estimators Predicting QoE in HTTP Adaptive Streaming
2022
The aim of adaptive HTTP streaming technology is preserving the best possible video streaming quality for viewers in heterogeneous network conditions. This can be achieved by making multiple quality versions of the video available. Switching between versions during playback should be imperceptible and fluent. The decision about quality-level switching is typically based on network capacity estimation and buffer occupancy, which predict the risk of stalling. Since quality-level switching and stalling are directly evident to the user, they are often classified as influence factors of quality of experience (QoE). In this paper, we observe different network capacity estimators and buffer behavi…
