Multi-objective DSE algorithms' evaluations on processor optimization

2013

Very complex micro-architectures, like complex superscalar/SMT or multicore systems, have lots of configurations. Exploring this huge design space and trying to optimize multiple objectives, like performance, power consumption and hardware complexity is a real challenge. In this paper, using the multi-objective design space exploration tool FADSE, we tried to optimize the hardware parameters of the complex superscalar Grid ALU Processor. We compared how different heuristic algorithms handle the DSE optimization. Three of these algorithms are taken from the jMetal library (NSGAII, SPEA2 and SMPSO) while the other two, CNSGAII and MOHC were implemented by us. We show that in this huge design …

Mating strategies and resulting patterns in mate guarding crustaceans : an empirical and theoretical approach

2012

Because of strong costs associated with each mating event, females are usually not as available for reproduction as males at any given time. Males are therefore in competition with each other for access to receptive females, hence leading to strong sexual selection. One textbook case of such a mating system occurs in moulting crustaceans where females can only be fertilized during a short period following their moult. This has favoured the evolution male strategies to monopolize females before their period of receptivity. Such a precopulatory mate guarding is widespread among many taxa and represents one of the most striking example of males’ competitive traits favoured by sexual selection.…

Personality Types and Applicant Reactions in Real-life Selection

2013

The study aimed to determine if an applicant's personality type is associated with his/her reactions (fairness perceptions, face validity perceptions, and predictive validity perceptions) to the selection process. The participants (N = 258) were real-life applicants for admission to a vocational school. A person-centered approach was applied to find subgroups with similar personality profiles. Latent profile analysis found four personality types: Resilient (45%), Overcontrolled (13%), Undercontrolled (10%), and Bohemian (32%). The Resilient and Bohemian personality types had more favorable perceptions of test fairness than the Overcontrolled type. Personality type did not affect face validi…

The Selection and Deselection of Technocratic Ministers in Democratic Spain

2017

This chapter analyses the presence of non-political ministers in the Spanish cabinet in the democratic period since 1977, where one out of five ministers did not belong to the ruling party at the time of her appointment and one out of three can be considered as a non-political minister. By observing the selection and deselection of these individuals, it shows the cabinet dynamic behind the ministerial appointments and the differences between the more political type of ministers and those coming from outside political pathways. Despite some outstanding exceptions, non-political ministers are often recruited from outside the parliament and have fewer chances to develop a relevant ministerial …

Proces selekcji kandydatów partii politycznych w wyborach Prezydenta RP – motywacje, dylematy, strategie

2022

Wybory prezydenckie pomimo dużego stopnia spersonalizowania, stanowią ważną przestrzeń rywalizacji międzypartyjnej. Doświadczenia polskich elekcji prezydenckich pokazują, że są one zdominowane przez kandydatów partyjnych. Podstawowym celem niniejszego artykułu, jest ukazanie procesu selekcji kandydatów partii politycznych na urząd Prezydenta RP, jako jednego z kontekstów wyborów prezydenckich w Polsce. Istotnym punktem rozważań jest odniesienie wskazanego procesu do aktywności przywódców partyjnych w tym zakresie, a dokładnie zauważalnej tendencji do rezygnacji z kandydowania. Trend ten wiąże się z wykorzystywaniem przez partie polityczne tzw. surogatów, czyli kandydatów zastępczych. Porusz…

Effects of a French remedial program on pupils’ educational outcomes

2018

International audience; Few studies have examined the French “Networks for Specialized Assistance to Pupils in Difficulty” (Rased). In this article, we evaluate the impact of receiving Rased services in the first year of primary schooling on academic success. Using data from a national panel study, we find inconsistency in student selection within Rased. Using matching methods, our results reveal that pupils who benefited from the program school have a higher probability of grade repetition and obtain significantly lower scores on the third grade national assessment, particularly in mathematics, compared to pupils with similar characteristics who did not take part in the program. This impac…

Sequence evolution, processing, and posttranslational modification of zonadhesin D domains in primates, as inferred from cDNA data

2005

Zonadhesin is a mammalian transmembrane sperm ligand. Precursor zonadhesin essentially consists of MAM (meprin/A5 antigen/mu receptor tyrosine phosphatase) domains, a mucin-like repeat, and D domains (homologous to von Willebrand D). Recent immunovisualization and binding assays indicate that zonadhesin D domains 1–3 bind postacrosomally to the zona pellucida. This feature has attracted considerable interest in the evolution of zonadhesin and its possible biological and biomedical implications. Previous molecular evolutionary analyses, however, were confined to cDNA sequences of only few distantly related species. Moreover, except for rabbit and pig, little is known about zonadhesin’s proce…

Interspecific attraction between ground-nesting songbirds and ants: the role of nest-site selection

2021

Abstract Background Interspecific interactions within ecological networks can influence animal fitness and behaviour, including nest-site selection of birds and ants. Previous studies revealed that nesting birds and ants may benefit from cohabitation, with interspecific attraction through their nest-site choice, but mutual interactions have not yet been tested. We explored a previously undescribed ecological link between ground-nesting birds and ants raising their own broods (larvae and pupae) within the birds’ nests in a temperate primeval forest of lowland Europe. We tested whether the occurrence of ant broods within bird nests resulted from a mutual or one-sided interspecific attraction …
