Application of value analysis for integral and objective evaluation of university lecturers

La feina dels professors a la universitat s'avalua en àmbits molt diversos: docència, investigació, compromís amb la universitat, etc. La majoria de vegades aquesta avaluació es fa de forma segregada, malgrat que forma part integrada de l'activitat del professor amb evidents interaccions entre les seves parts. És per això que és molt útil tenir una metodologia d'avaluació que consideri els múltiples criteris de forma conjunta. L'objectiu d'aquest article és aplicar la metodologia del model integrat de valor per a avaluacions sostenibles (MIVES) per a la selecció de candidats en una habilitació a càtedra. Mitjançant MIVES, es pretén tenir en compte de forma integrada els diferents aspectes que conformen l'activitat ordinària d'un professor, tant en l'entorn intern de la mateixa universitat, com en l'extern, tant si és professional, acadèmic com social. El sistema MIVES planteja una estructura integral per a l'avaluació, utilitza funcions de valor per a l'homogeneïtzació de les unitats de cada un dels criteris definits i aplica un procés d'anàlisi jeràrquica de comparació entre iguals per a l'obtenció dels pesos relatius. MIVES es va aplicar en una primera habilitació a càtedra amb unes deduccions concordants amb els resultats de les proves. En l'article s'exposa aquesta metodologia aplicada en un segon procés d'habilitació l'objectiu del qual era verificar si el model funcionava en una altra àrea de coneixement. Els resultats obtinguts van tornar a ser consistents amb els resultats reals de les proves.El trabajo de los profesores en la universidad se evalúa en ámbitos muy diversos: docencia, investigación, compromiso con la universidad, etc. En la mayoría de las ocasiones esta evaluación se hace de forma segregada, a pesar de formar parte integrada de la actividad del profesor con evidentes interacciones entre sus partes.

For this reason, it is very useful to have an evaluation methodology which takes into consideration all the criteria as a whole. The aim of this article is to apply the MIVES model (integrated methodology of value for sustainable evaluation) for the selection of candidates for professorship. The aim of MIVES is to take into account all the different aspects involved in the normal activity of a lecturer, within the environment of the university itself as well as externally, in professional, academic and social areas. The MIVES system puts forward an integral structure for evaluation, using value functions to standardise the units of each of the defined criteria, and applying a system of peer comparison to assign a relative weight to each criterium. MIVES has been applied to qualify a lectureship with conclusions in agreement with the results of the aforementioned evaluated areas. This article discusses this methodology applied to a second process of qualification whose aim was to verify whether the model functions in another area of knowledge. The results obtained were consistent with those of the aforementioned evaluations

Fatigue behavior of polymer-modified porous concretes

Highly permeable materials provide drainage and noise absorption properties that are useful in pavement top-layers. In such porous concretes, the voids reduce the mechanical integrity, which may have to be compensated by the incorporation of non-conventional components, such as polymers. A basic property needed for the design of pavements is the fatigue behavior of the material, which has not been studied thoroughly for polymer modified porous concretes. The paper presents experimental results of fatigue tests in compression in terms of Wöhler curves for four porous concretes (two of them with polymer). It is seen that the polymer modified porous concretes exhibit better fatigue behavior than those without polymer. However, the improvement decreases for low values of the stress level, S, and appears to be negligible for the case of traffic loads in main roads or highways (number of load cycles, N >106). Additionally, the deformation and internal temperature evolutions have been monitored, and it is concluded that their trends are similar to those of conventional concrete, with temperature increases significantly higher than in conventional concretes.Peer Reviewe

Intraaortic balloon counterpulsation as a temporary support measure in decompensated critical aortic stenosis

Intraaortic balloon counterpulsation was instituted in two adult patients whose condition was rapidly deteriorating because of critical decompensated valvular aortic stenosis. The acute hemodynamic effect of counterpulsation in these patients was compared with the effect of counterpulsation in three control patients with unstable angina and no aortic valve disease. Augmentation of aortic diastolic pressure was similar in both groups; however, in contrast to the patients with unstable angina, the patients with aortic stenosis had no decrease in left ventricular systolic pressure. Counterpulsation resulted in an increase in the transvalvular pressure gradient, which was associated with a slight increase in stroke volume. In both patients with aortic stenosis, the institution of counterpulsation resulted in marked clinical improvement, which facilitated successful valve replacement surgery.The benefit from counterpulsation in critically decompensated aortic stenosis appears to be derived almost entirely from augmentation of the diastolic coronary filling gradient. The improvement that results from counterpulsation suggests that ischemia is the major cause of decompensation

Evaluation of two highly porous microcrystalline biphasic calcium phosphate-based bone grafts for bone regeneration: An experimental study in rabbits

A biphasic bone grafting biomaterial based on a mixture of calcium phosphates and beta-tricalcium phosphate (β-TCP) phases with high nanoporosity was synthesized. The synthesis route was based on calcium phosphate composition and the incorporation of glycolic acid as a pore former, giving a material composed of 97% β-TCP and 3% calcium orthophosphates (CaPO4). An in vitro study of the purity, microstructure, crystalline domain, and pores size for the material obtained was performed by SEM analysis as well as full structural characterization. The region of interest related to the surface was determined by the specific surface area measured with the BET method. In vivo evaluation of bone response was performed by implanting the new low-cost biphasic manufacturing material synthesized in this work, which was compared with a biphasic material of similar chemical and microstructural composition existing in the commercial market and with higher cost called Synergy Odontit® β-TCP. The materials were implanted separately into 5 mm diameter defects in the tibias of New Zealand White rabbits at 30, 60, and 90 days. The results obtained showed that the host tissue well accepted the new biphasic material; the presence of new bone formation was observed. A more complete resorption was observed for the new microcrystalline biphasic material compared to for a commercial β-TCP material.Fil: Garcés-Villalá, Miguel Ángel. Fundación Corazón de Jesús.

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
