Tensions and expression in Milos Forman’s American films
2012
Milos Forman’s American films require a plural outlook. The director has always been drawn to stories of conflicts that are essential, according to him, to study human passion. This tension, thematic as well as esthetic, allows him to show the smallest mechanisms that lead to oppression in European and American stories, providing the viewer with a lesson of anatomy that pinpoints the most invisible magnetic forces leading to power. This course is accompanied by a journey to individualism, through forces involved in the identification with attractive though realistic characters, through the rediscovery of individual freedom within primitive or regressive worlds, insisting on the necessity of…
Data from: Odor diversity decreases with inbreeding in the ant Hypoponera opacior
2016
Reduction in heterozygosity can lead to inbreeding depression. This loss of genetic variability especially affects diverse loci, such as immune genes or those encoding recognition cues. In social insects, nestmates are recognized by their odor, i.e. their cuticular hydrocarbon profile. Genes underlying hydrocarbon production are thought to be under balancing selection. If so, inbreeding should result in a loss of chemical diversity. We show here that cuticular hydrocarbon diversity decreases with inbreeding. Studying an ant with a facultative inbreeding lifestyle we found inbred workers to exhibit both a lower number of hydrocarbons and less diverse, that is, less evenly-proportioned profil…
Does risk of predation by mammalian predators affect the spacing behaviour of rodents? Two large-scale experiments.
2000
Predator-prey interactions between small mammals and their avian and mammalian predators have attracted much attention. However, large-scale field experiments examining small-mammal antipredatory responses under the risk of predation by mammals are rare. As recently pointed out, the scale of experiments may cause misleading results in studies of decision-making under predation risk. We studied the effect of small mustelid predators on the spacing behaviour of the gray-tailed vole (Microtus canicaudus) and the bank vole (Clethrionomys glareolus) in two separate field enclosure experiments. The experiments were conducted during the breeding season in North America and northern Europe, where s…
Phenotypic Flexibility in the Social Organization of Clethrionomys
1990
I review the flexibility of social organization and spacing behavior in Clethrionomys. This review is based on a 6-year comparative study and several experimental studies on cyclic populations of the bank vole, C. glareolus, in Central Finland. The social organization of Clethrionomys populations shows great flexibility during both the breeding and nonbreeding season, and is dependent on habitat patchiness, food availability, Predation, kinship, philopatry, and familiarity between individuals. The first three factors are most important in destabilizing a population, whereas the last three stabilize a population without exhausting its resources. Female territoriality can weaken in a producti…
A Comparative Study of Phenotypic Changes in Microtus Social Organization
1990
Monogamy, polygyny, and promiscuity have been found in populations of M. oeconomus and M. agrestis in different environmental situations in northern Finland. Thus the mating systems seem to be more variable both between and within species in Microtus than in Clethrionomys. Spacing behavior in Microtus caused a temporary decline in population density in mid-summer, but in Clethrionomys a decline occurred only in the beginning of the breeding season. Habitat quality affected spacing behavior in similar ways in Microtus and Clethrionomys but did not affect differences in breeding limitation. Despite the differences in population regulation, both Clethrionomys and Microtus populations cycle syn…
Fundamentals and applications of stir bar sorptive dispersive microextraction: A tutorial review
2021
Current trends in sample preparation focus on the miniaturization of the process resulting in what is known as microextraction techniques. Among them stir bar sorptive dispersive microextraction (SBSDME) is one of the most recent techniques. It was presented a few years ago as a hybrid microextraction technique that combines the principles of stir bar sorptive extraction (SBSE) and dispersive solid phase extraction (DSPE). This novel technique introduces, into the sample solution, a bar-shaped magnet coated with a magnetic (nano)material, which is maintained on the surface by magnetism. Once stirring starts, the competitive action between magnetism and rotational force is exploited. At low …
Applicability of Interference Coordination in Highly Loaded HSUPA Network
2010
This paper evaluates the performance of highly loaded High Speed Uplink Packet Access (HSUPA) network with and without network wide static Interference Coordination (IC). IC alternates the priorities for user transmission periods throughout the network to achieve reduced interference levels and higher performance. A large variety of combinations including, e.g., different schedulers, cell center/edge user definitions (user splits) and interference targets are investigated in this paper. Performance is analyzed using a quasi-static system level simulator which is also used to support Third Generation Partnership Project (3GPP) standardization work. The simulator contains detailed and commonl…
Apoyo a la autonomía, satisfacción de las necesidades psicológicas y bienestar : invarianza de un modelo estructural en futbolistas y bailarines
2015
La teoría de las necesidades psicológicas básicas (Deci y Ryan, 2000) defiende que en los contextos sociales en los que se apoya la autonomía se promueve el bienestar a través de la satisfacción de las necesidades psicológicas básicas. En base a este marco teórico, el objetivo del presente trabajo fue triple: primero, poner a prueba un modelo en el que se analizaba la secuencia: percepción del apoyo a la autonomía ofrecido por el profesor/entrenador - satisfacción de las necesidades psicológicas básicas - bienestar; segundo, examinar el papel mediador de las necesidades, y tercero, estudiar la invarianza del modelo entre dos poblaciones. Participaron 197 bailarines (Medad = 18,65 ± 3,73) y …
Medical news aggregation and ranking of taking into account the user needs
2019
The purpose of this work is to develop an intelligent information system that is designed for aggregation and ranking of news taking into account the needs of the user. The online market for mass media and the needs of readers, the purpose of their searches and moments is not enough to find the news is analyzed. A conceptual model of the information aggression system and ranking of news that would enable presentation of the work of the future intellectual information system, to show its structure is constructed. The methods and means for implementation of the intellectual information system are selected. An online resource for aggregation and ranking of news, news feeds and flexible setting…
Genome structure in Sicilian cattle breeds
2014
Genomic technologies provide background information concerning genome structure in domestic animals. The aim of this work was to investigate the genetic structure and the patterns of linkage disequilibrium (LD) in two Sicilian local cattle breeds, Cinisara and Modicana. Genotypes from animals of Italian Holstein breed were also used to investigate the relationship among breeds. Structure software was used to analyze the genetic structure and assign the individuals to each cluster. The genetic relationship between individuals was estimated by Principal Components Analysis (PCA) of genetic distance. A standard descriptive LD parameter (r2) was obtained between adjacent SNPs and for all pairwi…
