The immunodominant CD8 T cell response to the human cytomegalovirus tegument phosphoprotein pp65(495-503) epitope critically depends on CD4 T cell he…
2011
Abstract Immunodominance hierarchies operating in immune responses to viral Ags limit the diversity of the elicited CD8 T cell responses. We evaluated in I-Ab+/A2-HHD-II and HLA-DR1+/A2-DR1 mice the HLA-A*0201–restricted, multispecific CD8 T cell responses to the human CMV tegument phosphoprotein pp65 (pp65) Ag. Vaccination of mice with pp65-encoding DNA elicited high IFN-γ+ CD8 T cell frequencies to the pp65495–503/(e6) epitope and low responses to the pp65320–328/(e3) and pp65522–530/(e8) epitopes. Abrogation of the e6-specific immunity efficiently enhanced e3- and e8-specific T cell responses by a pp65Δ501–503 DNA vaccine. The immunodominant e6-specific (but not the e3- and e8-specific) …
The subplate and early cortical circuits.
2010
The developing mammalian cerebral cortex contains a distinct class of cells, subplate neurons (SPns), that play an important role during early development. SPns are the first neurons to be generated in the cerebral cortex, they reside in the cortical white matter, and they are the first to mature physiologically. SPns receive thalamic and neuromodulatory inputs and project into the developing cortical plate, mostly to layer 4. Thus SPns form one of the first functional cortical circuits and are required to relay early oscillatory activity into the developing cortical plate. Pathophysiological impairment or removal of SPns profoundly affects functional cortical development. SPn removal in v…
Dominance and leadership in research activities: Collaboration between countries of differing human development is reflected through authorship order…
2017
Introduction Scientific collaboration is an important mechanism that enables the integration of the least developed countries into research activities. In the present study, we use the order of author signatures and addresses for correspondence in scientific publications as variables to analyze the interactions between countries of very high (VHHD), high (HHD), medium (MHD), and low human development (LHD). Methodology We identified all documents published between 2011 and 2015 in journals included in the Science Citation Index-Expanded categories’ of Tropical Medicine, Infectious Diseases, Parasitology, and Pediatrics. We then classified the countries participating in the publications acco…

State and Religion in Ethiopia
2016
In this chapter, Steen-Johnsen presents a study of religious peacebuilding in Ethiopia to depict how religious peacebuilders are affected by the political strategies of state authorities related to civil society. She outlines how Ethiopian politics have been historically dominated by an Amhara-Orthodox elite. This dominance persists in contemporary political life in Ethiopia. Steen-Johnsen also presents the current political strategies of the Ethiopian authoritarian regime aimed at controlling political mobilization in the civil and religious spheres. She outlines how religious and civil actors in the country have historically been submissive to state authorities and suggests that this form…
Beyond ‘nasty neighbours’ and ‘dear enemies’? Individual recognition by scent marks in a lizard (Podarcis hispanica)
2008
True individual recognition (TIR), the ability to recognize conspecific individuals on the basis of identity cues, is required for the evolution of several social traits (e.g. the maintenance of dominance hierarchies). However, knowledge about the distribution and functional significance of TIR is scant in some vertebrate groups, such as reptiles. In this study we used a functional modification of a habituation-dishabituation paradigm to investigate the existence and adaptive significance of TIR in a territorial lizard (Podarcis hispanica, Lacertidae). Males discriminated between individual rivals of similar characteristics (e.g. size, weight, familiarity) solely on the basis of their scent…
Should I use touchscreen tablets rather than computers and mice in TDS trials?
2016
International audience; Internet technologies are increasingly used as tools in sensory analysis. Thus, it would be a natural step forward for sensory science to move beyond the laboratory, into people's homes. Therefore, working with consumer IT devices like touchscreen tablets in sensory science should be taken into consideration. Working with the intuitive concept of dominance, Temporal Dominance of Sensations (TDS) requires a non-analytical answer from the subject. Using a touchscreen tablet instead of a classic mouse could reduce the cognitive load and favor a more instinctive answer. Indeed, it was proven that touch interaction is natural and efficient, and that finger pointing is fas…

Law of Finance: Evidence from Finland
2003
Although it is widely acknowledged that the benefits of corporate governance reform could be substantial, systematic evidence on such reforms is scant. We both document and evaluate a contemporary corporate governance reform by constructing 18 measures of shareholder and creditor protection for Finland for the period 1980-2000. The measures reveal that shareholder protection has been strengthened whereas creditor protection has been weakened. We also demonstrate how the reform is consistent with a reorganisation of the Finnish financial market in which a bank-centred financial system shifted from relationship-based debt finance towards increasing dominance by the stock market. We find evide…
Gender differences in the jealousy-evoking effect of rival characteristics
2011
This study examines gender differences in the jealousy-evoking nature of rival characteristics in two Spanish-speaking countries (Argentina and Spain). A total of 388 Spanish students and 444 Argentinean students participated in the study. First, the cross-cultural validity of a Dutch scale containing 56 rival characteristics was examined. A factor analysis distinguished four dimensions (i.e., social power and dominance, physical attractiveness, physical dominance, and social-communal attributes). After the analysis, the final scale contained in total 24 items. Results showed that in Argentina and Spain combined, men experienced more jealousy than women when their rival was more physically …
