Early life of fathers affects offspring fitness in a wild rodent

2019

Intergenerational fitness effects on offspring due to the early life of the parent are well studied from the standpoint of the maternal environment, but intergenerational effects owing to the paternal early life environment are often overlooked. Nonetheless, recent laboratory studies in mammals and ecologically relevant studies in invertebrates predict that paternal effects can have a major impact on the offspring's phenotype. These non‐genetic, environment‐dependent paternal effects provide a mechanism for fathers to transmit environmental information to their offspring, and could allow rapid adaptation. We used the bank vole Myodes glareolus, a wild rodent species with no paternal care, t…

Role ambiguity among school principals in China and Finland

2012

This study explores the role-ambiguity phenomenon among public secondary school principals in China and Finland. Organizational dysfunction caused by role ambiguity in professional organizations has been studied since the 1960s (Kahn et al, 1964). Although role ambiguity occurs most frequently in educational organizations, few studies on role ambiguity are found on school leaders. This study contributes to this topic by building a multidimensional knowledge structure of role ambiguity among school principals. It applies a qualitative design with case study as its approach. The data was collected through ten individual interviews with upper secondary school principals in Shanghai and the Cen…

Who am i : reconstructing cultural identity upon reentry

2012

The topic of this thesis is reentry adaptation and its effects on an individual’s cultural identity. The purpose of the study is to find out what kinds of problems may arrive during reentry adaptation, how identity is changed as a result of intercultural experiences, as well as what kinds of communication strategies help the entire adaptation process. The aim of the study is to examine what kinds of factors should be taken into account during reentry in order to make it easier on the returnees. In addition the aim is to investigate how individuals are able to comprehend their new cultural identity and in which ways they are able to communicate the possible changes to friends and family at h…

The effect of spatial and temporal scale on camouflage in North African rodents

2022

Abstract Background matching, a common form of camouflage, is a widespread anti-predator adaptation that hinders detection or recognition by increasing the resemblance of prey to its environment. However, the natural environment is complex and both spatially and temporally variable, which constrains effective background matching as an anti-predator strategy. Here, using remote sensing data (publicly available satellite imagery), we investigated how variation of habitat parameters predicts background matching in 16 Sahara–Sahel rodent species across spatial and temporal scales. All fur colour parameters (hue, saturation and brightness) strongly matched the respective habitats of the differen…

Putative sorting signals involved in PIN1 trafficking

2013

Las auxinas son hormonas vegetales involucradas en muchos procesos fisiológicos, tales como el crecimiento y diferenciación celular, la maduración de los frutos, la floración o los tropismos. Su transporte a través de la planta es polar, jugando un papel esencial en la regulación del crecimiento y el desarrollo y contribuyendo al mantenimiento de la polaridad global de la planta. La polaridad en el flujo de auxinas es debida, al menos en parte, a la distribución polar de los transportadores de salida de auxina de la familia PIN. En Arabidopsis thaliana se han identificado 8 transportadores PIN diferentes. Todos ellos presentan una estructura similar, con un dominio citosólico central que se…

Effect of Cycloplegia on Blur Perception Thresholds as Measured by Source Method

2017

Abstract One of the advantages of a source method over observer method in blur perception measurements is better control of a stimulus blur level, which is achieved with computerised image processing unlike the observer method that requires optical defocusing of the observer. The aim of this study was to determine if paralysation of accommodation has effect on blur perception thresholds, thereby evaluating its necessity in such experiments. Blur perception thresholds (just noticeable blur, clear image, recognition, and non-resolvable blur thresholds) were evaluated with (using cycloplegia) and without paralysed accommodation to determine effect on blur perception. A computerised low-pass sp…
