Algunas condiciones necesarias para la gestión y organización en la universidad

[ES] La crisis del Estado de Bienestar y las Sociedades del Conocimiento generan una crisis en el actual sistema universitario. Este se queda sin respuestas claras y ante un panorama de fines y objetivos difuso y confuso. Frente a estas situaciones, la gestión y la organización devienen en factores estratágicos clave, y esto es así por el potencial competitivo de ambas en el ámbito universitario en particular.

Ongizate estatua kolokan Espainian : pentsioen erreformak

This paper analyzes the pensions reforms and changes that have been in Spain to guarantee Welfare State. In fact, pensions are the most important part that we have to control in order to satisfy the necessities of a country: who and what conditions in we have to receive them, what have to be the financial source or sources etcetera. Because of that, this paper summarizes the reforms have been until nowadays, what are the reasons of these changes and what have been the impacts as much on workers as on pensioners. Apart from that, we are going to analyze the factor to cause gender differences. Finally, it suggests some restraints that the state must to impose in the medium term to remove unfair elements that the last reform causes and to guarantee solvency in the long term.

The impact of economic crises on social inequalities in health: what do we know so far?

Since 2008, Western countries are going through a deep economic crisis whose health impacts seem to be fundamentally counter-cyclical: when economic conditions worsen, so does health, and mortality tends to rise. While a growing number of studies have presented evidence on the effect of crises on the average population health, a largely neglected aspect of research is the impact of crises and the related political responses on social inequalities in health, even if the negative consequences of the crises are primarily borne by the most disadvantaged populations. This commentary will reflect on the results of the studies that have analyzed the effect of economic crises on social inequalities in health up to 2013. With some exceptions, the studies show an increase in health inequalities during crises, especially during the Southeast Asian and Japanese crises and the Soviet Union crisis, although it is not always evident for both sexes or all health or socioeconomic variables. In the Nordic countries during the nineties, a clear worsening of health equity did not occur. Results about the impacts of the current economic recession on health equity are still inconsistent. Some of the factors that could explain this variability in results are the role of welfare state policies, the diversity of time periods used in the analyses, the heterogeneity of socioeconomic and health variables considered, the changes in the socioeconomic profile of the groups under comparison in times of crises, and the type of measures used to analyze the magnitude of social inequalities in health. Social epidemiology should further collaborate with other disciplines to help produce more accurate and useful evidence about the relationship between crises and health equity.

Krisi ekonomikoaren eragina Espainiako Ongizate Estatuan

[EU]Ongizate Estatua demokraziarekin sortu zen, eta hiritarrek bizitza duina lortzeko eratu egin zen. Urteetan zehar Ongizate Estatuak krisiak izan ditu, zeinetan honen biziraupena kolokan jarri den. Oraingoan, 2008ko krisi ekonomikoarekin, hauetako krisi bat bizitzen ari da. Hori dela eta, lan honetan Ongizate Estatuak krisiarekin izandako bilakaera aztertuko da; batez ere, Espainiaren ongizatean izandako kalteak eta murrizketak krisi ekonomikoaren etorreragatik. Horretarako, 2007 eta 2015 urteak konparatu eta aztertuko dira, Estatuaren ongizatean begia jarriz. Horretaz gain, FBBVA-IVIE txosnenaren bitartez, Autonomia Erkidegoek duten gastu sozialen eskumenetan kalteak ere izan diren aztertuko da. Laburbilduz, Espainiako Ongizate Estatuan krisi ekonomikoak zer nolako eraginak izan dituen aztertu egingo da, eragin gehienak murrizketak izanik gastu sozialetan, biztanleriaren bizi-kalitatea zuzenki kaltetuz.

Reference Points and Optimal Management in Stochastic Age-Structured Fisheries Models

The purpose of this article is to characterize dynamic optimal harvesting trajectories that maximize discounted utility assuming an age-structured population model, in the same line as Tahvonen (2009). The main novelty of our study is that uses as an age-structured population model the standard stochastic cohort framework applied in Virtual Population Analysis for fish stock assessment. This allows us to compare optimal harvesting in a discounted economic context with standard reference points used by fisheries agencies for long term management plans (e.g. Fmsy). Our main findings are the following. First, optimal steady state is characterized and sufficient conditions that guarantees its existence and uniqueness for the general case of n cohorts are shown. It is also proved that the optimal steady state coincides with the traditional target Fmsy when the utility function to be maximized is the yield and the discount rate is zero. Second, an algorithm to calculate the optimal path that easily drives the resource to the steady state is developed. And third, the algorithm is applied to the Northern Stock of hake. Results show that management plans based exclusively on traditional reference targets as Fmsy may drive fishery economic results far from the optimal.

Reference Points Based on Dynamic Optimisation: A Versatil Algorithm for Mixed Fishery Management with Bio-economic Agestructured Models

Single-species management objectives may not be consistent within mixed fisheries. They may lead species to unsafe situations, promote discarding of over-quota and/or misreporting of catches. We provide an algorithm for characterising bio-economic reference points for a mixed fishery as the steady-state solution of a dynamic optimal management problem. The optimisation problem takes into account: i) that species are fishing simultaneously in unselective fishing operations and ii)intertemporal discounting and fleet costs to relate reference points to discounted economic profits along optimal trajectories. We illustrate how the algorithm can be implemented by applying it to the European Northern Stock of Hake (Merluccius merluccius), where fleets also capture Northern megrim (Lepidorhombus whiffiagonis) and Northern anglerfish (Lophius piscatorius and Lophius budegassa). We find that optimal mixed management leads to a target reference point that is quite similar to the 2/3 of the Fmsy single-species (hake) target. Mixed management is superior to singlespecies management because it leads the fishery to higher discounted profits with higher long-term SSB for all species. We calculate that the losses due to the use of the Fmsy single-species (hake) target in this mixed fishery account for 11.4% of total discounted profits.

Fault-tolerant almost exact state transmission

We show that a category of one-dimensional XY-type models may enable high-fidelity quantum state transmissions, regardless of details of coupling configurations. This observation leads to a fault-tolerant design of a state transmission setup. The setup is fault-tolerant, with specified thresholds, against engineering failures of coupling configurations, fabrication imperfections or defects, and even time-dependent noises. We propose an experimental implementation of the fault-tolerant scheme using hard-core bosons in one-dimensional optical lattices.

Stability analysis and observer design for discrete-time SEIR epidemic models

This paper applies Micken's discretization method to obtain a discrete-time SEIR epidemic model. The positivity of the model along with the existence and stability of equilibrium points is discussed for the discrete-time case. Afterwards, the design of a state observer for this discrete-time SEIR epidemic model is tackled. The analysis of the model along with the observer design is faced in an implicit way instead of obtaining first an explicit formulation of the system which is the novelty of the presented approach. Moreover, some sufficient conditions to ensure the asymptotic stability of the observer are provided in terms of a matrix inequality that can be cast in the form of a LMI. The feasibility of the matrix inequality is proved, while some simulation examples show the operation and usefulness of the observer.
