Split decomposition A technique to analyze viral evolution
1993
A clustering technique allowing a restricted amount of overlapping and based on an abstract theory of coherent decompositions of finite metrics is used to analyze the evolution of foot-and-mouth disease viruses. The emerging picture is compatible with the existence of viral populations with a quasispecies structure and illustrates various forms of evolution of this virus family. In addition, it allows the correlation of these forms with geographic occurrence.
LIFE CARE ANNUITIES (LCA) EMBEDDED IN A NOTIONAL DEFINED CONTRIBUTION (NDC) FRAMEWORK
2016
AbstractThis paper examines the possibility of embedding public long-term care (LTC) insurance within the retirement pension system, i.e. introducing life care annuities into a notional defined contribution framework. To do this, we develop a multistate overlapping generations model that includes the so-called survivor dividend and give special attention to the assumptions made about mortality rates for dependent persons and LTC incidence rates, which largely determine the contribution rate assigned to LTC. The proposed model could be of interest to policymakers because it could be implemented without too much difficulty, it would universalize LTC coverage with a “fixed” cost, and it would …
Integrating retirement and permanent disability in NDC pension schemes
2015
ABSTRACTIn this article, we develop a theoretical basis for integrating retirement and permanent disability using a generic nonfinancial defined contribution framework. The methodology we use relies on a multistate overlapping generations model that includes the so-called survivor dividend. Currently, this feature can only be found in the Swedish defined contribution (DC) scheme. The results achieved in the numerical example we present endorse the fact that the model works well. Special attention is given to the assumptions made about mortality rates for disabled people and disability incidence rates, which largely determine the contribution rate assigned to disability. The model could be o…
Sequential design of multioverlapping controllers for structural vibration control of tall buildings under seismic excitation
2012
In this article, a computationally effective strategy to obtain multioverlapping controllers via the inclusion principle is applied to design a state-feedback multioverlapping linear-quadratic regulator controller for a 20-story building. The proposed semidecentralized controller only requires state information of neighboring stories to compute the corresponding control actions. This particular information exchange configuration allows introducing a dramatic reduction in the transmission range required for a wireless implementation of the communications system. More specifically, just a one-story transmission range is required by the proposed multioverlapping controller, while a full-buildi…
Immunization Strategies Based on the Overlapping Nodes in Networks with Community Structure
2016
International audience; Understanding how the network topology affects the spread of an epidemic is a main concern in order to develop efficient immunization strategies. While there is a great deal of work dealing with the macroscopic topological properties of the networks, few studies have been devoted to the influence of the community structure. Furthermore, while in many real-world networks communities may overlap, in these studies non-overlapping community structures are considered. In order to gain insight about the influence of the overlapping nodes in the epidemic process we conduct an empirical evaluation of basic deterministic immunization strategies based on the overlapping nodes.…
De Finnis cornutis
2014
<p><em>Horned Finns</em>. The ‘cornuti Finni’ mentioned in the <em>Historia Norwegiae</em> have not found their explanation, because the Latin word <em>cornu</em>, from which the adjective is derived, has been understood in the strict sense of ‘horn on the head’. The Latin word, however, also means ‘hoof’ of horses or ‘cloven hoof’ of cows and goats, even of the mythologic Faunus and Pan. In December 1913 Kai Donner saw in Dudinka Avam-Samojeds, who because of their cylindrically shaped reindeer winter boots, the front of which was hoof-shaped, were called ‘hoofed men’ (in Finnish ‘kaviolliset miehet’). In the extracts of Aristeas of Proconnesus, wh…
Transcriptional and Structural Study of a Region of Two Convergent Overlapping Yeast Genes
1999
The exceptionally close packing of many yeast genes and other chromosomal elements raises the question of how those elements are functionally insulated. All published work shows that natural insulators are very effective, but transcriptional interference (TI) occurs if they are mutated or if their natural context is altered. Mechanisms to avoid TI are poorly understood, but are thought to involve an interplay of cis sequences and trans factors in a chromatin context. We have studied the case of two convergent closely packed ORFs (56 bp of separation) in chromosome IX of Saccharomyces cerevisiae. mRNAs from POT1 and YIL161w overlap by up to 115 nt. Convergent transcription causes a small but…
Persistence of Occupational Segregation: The Role of the Intergenerational Transmission of Preferences
2007
This article provides an explanation of the evolution and persistence of the women's segregation in jobs with less on-the-job training opportunities within the framework of an overlapping generations model with intergenerational transmission of preferences. ‘Job-priority’ and ‘family-priority’ preferences are considered. Firms’ policy and the distribution of women's preferences are endogenously and simultaneously determined in the long run. The results show though the gender gap in training will diminish, it will also persist over time. This is because both types of women's preferences coexist at the steady state due to the socialisation effort of parents to preserve their own cultural valu…
Pension Schemes and Falling Birth-Rates: Change in Customs or Microeconomic Optimization?
2004
In this paper, we develop an overlapping generations model where fertility is endogenous. The utility of the parents is a function of the number of their children, and each child implies two types of fixed costs: the financial cost and the cost in terms of time. A "pay-as-you-go" pension scheme introduces an externality in that the number of children will be fewer than optimal because their favorable impact on the level of pension income is not taken into account. First, we define the competitive equilibrium dynamics and the steady state. This allows comparisons with the optimal stationary state, a notion which generalizes the golden rule. Two instruments, pensions and child benefits, are n…
