Performance-based university funding and the drive towards ‘institutional meritocracy’ in Italy

Many countries, including Italy, are increasingly managing their public higher education systems in accordance with the New Public Management principle that private-sector management practices improve efficiency and quality. A key mechanism has been the introduction of performance-based funding systems designed to reward ‘high-performing’ institutions and incentivise ‘lesser-performing’ institutions to improve. Instead of improving efficiency and quality across the board, however, we argue that performance-based funding systems naturalise longstanding structurally determined inequalities between institutions by recasting national higher education systems as competitive institutional meritocracies in which institutional inequalities are redefined as objective indicators of intrinsic ‘merit’ or worth. We illustrate how performance-based university funding systems naturalise pre-existing inequalities between universities drawing on the case of Italy, a country characterised by longstanding inequalities between its northern and southern regions which demonstrably impact on the apparent ‘performance’ of universities. The concept of institutional meritocracy captures the illusory nature of this performance game

Efecto del porcentaje de inclusión de lisina sobre la productividad en cerdos de cebo

Las necesidades en lisina (Lys) de cerdos de altos crecimientos sacrificados para venta en fresco han sido estudiadas en detalle (NRC, 1998; BSAS, 2003; Fedna, 2006). Sin embargo, las necesidades de cerdos destinados a la obtención de productos curados, en los que se precisa obtener canales con porcentajes de grasa óptimos, han sido poco estudiadas (Beaulie et al., 2009). A ello hay que sumarle que en los últimos años la genética se ha centrado en mejorar la eficiencia alimenticia, lo que en muchos casos penaliza el contenido graso de las partes nobles (Blanchard et al., 1999; Latorre et al., 2003). Conocer las necesidades en Lys de cerdos de alta producción es clave; un déficit de Lys conlleva un menor crecimiento mientras que el exceso es caro. Por ello, el objetivo de este estudio fue estudiar el efecto del nivel de inclusión de Lys sobre los rendimientos productivos en cerdos de alta selección sacrificados a 113 kg destinados a la producción de productos curados

Modeling the Searching Behavior of Social Monkeys

We discuss various features of the trajectories of spider monkeys looking for food in a tropical forest, as observed recently in an extensive {\it in situ} study. Some of the features observed can be interpreted as the result of social interactions. In addition, a simple model of deterministic walk in a random environment reproduces the observed angular correlations between successive steps, and in some cases, the emergence of L\'evy distributions for the length of the steps.Comment: 7 pages, 3 figure

Symmetry broken motion of a periodically driven Brownian particle: nonadiabatic regime

We report a theoretical study of an overdamped Brownian particle dynamics in the presence of both a spatially modulated one-dimensional periodic potential and a periodic alternating force (AF). As the periodic potential has a low symmetry (a ratchet potential) the Brownian particle displays a broken symmetry motion with a nonzero time average velocity. By making use of the Green function method and a mapping to the theory of Brillouin bands the probability distribution of the particle coordinate is derived and the nonlinear dependence of the macroscopic velocity on the frequency and the amplitude of AF is found. In particular, our theory allows to go beyond the adiabatic limit and to explain the peculiar reversal of the velocity sign found previously in the numerical analysis.Comment: 4 pages, 2 figure

Current reversal with type-I intermittency in deterministic inertia ratchets

The intermittency is investigated when the current reversal occurs in a deterministic inertia ratchet system. To determine which type the intermittency belongs to, we obtain the return map of velocities of particle using stroboscopic recording, and numerically calculate the distribution of average laminar length ${}$. The distribution follows the scaling law of ${} \propto {\epsilon}^{-1/2}$, the characteristic relation of type-I intermittency.Comment: 4 pages, 7 figure

Apoyo a la autonomía, creencias implícitas de habilidad y metas de logro en jugadoras de baloncesto en formación

El objetivo principal del estudio fue analizar las relaciones entre el apoyo a la autonomía de entrenadores, compañeras, padres y madres, las creencias implícitas de habilidad y las metas de logro 2 x 2 de un grupo de jugadoras de baloncesto. La muestra estuvo compuesta por 57 jugadoras de baloncesto de la cantera de un equipo de baloncesto de Huelva. Estas jugadoras tenían entre los 10 y los 17 años (M = 13.02; DT = 1.90). Se midió el clima de apoyo a la autonomía del entrenador, de las compañeras, de padres y madres percibido por las jugadoras, las creencias implícitas de habilidad y las metas de logro 2x2. Los resultados del análisis de regresión lineal muestran que el clima de apoyo a la autonomía generado por el entrenador predice la meta de aproximación al rendimiento y la habilidad incremental. A su vez, la habilidad incremental predice las metas de aproximación y evitación a la maestría. Esto pone de manifiesto la importancia de generar climas de soporte a la autonomía de las jugadoras de baloncesto durante su formación, ya que adoptarán metas de logro más adaptativas.

Notes on Properties of Holographic Matter

Probe branes with finite worldvolume electric flux in the background created by a stack of Dp branes describe holographically strongly interacting fundamental matter at finite density. We identify two quantities whose leading low temperature behavior is independent of the dimensionality of the probe branes: specific heat and DC conductivity. This behavior can be inferred from the dynamics of the fundamental strings which provide a good description of the probe branes in the regime of low temperatures and finite densities. We also comment on the speed of sound on the branes and the temperature dependence of DC conductivity at vanishing charge density.Comment: 18 pages, 2 figures; v2: corrected error in Section 6, conclusions unchanged; v3: improved figures and added clarifying comment

Factors related to social support in neurological and mental disorders

Despite the huge body of research on social support, literature has been primarily focused on its beneficial role for both physical and mental health. It is still unclear why people with mental and neurological disorders experience low levels of social support. The main objective of this study was to explore what are the strongest factors related to social support and how do they interact with each other in neuropsychiatric disorders. The study used cross-sectional data from 722 persons suffering from dementia, depression, epilepsy, migraine, multiple sclerosis, Parkinson's disease, schizophrenia, stroke, and substance use disorders. Multiple linear regressions showed that disability was the strongest factor for social support. Extraversion and agreeableness were significant personality variables, but when the interaction terms between personality traits and disability were included, disability remained the only significant variable. Moreover, level of disability mediated the relationship between personality (extraversion and agreeableness) and level of social support. Moderation analysis revealed that people that had mental disorders experienced lower levels of support when being highly disabled compared to people with neurological disorders. Unlike previous literature, focused on increasing social support as the origin of improving disability, this study suggested that interventions improving day-to-day functioning or maladaptive personality styles might also have an effect on the way people perceive social support. Future longitudinal research, however, is warranted to explore causality

Holographic Thermodynamics at Finite Baryon Density: Some Exact Results

We use the AdS/CFT correspondence to study the thermodynamics of massive N=2 supersymmetric hypermultiplets coupled to N=4 supersymmetric SU(Nc) Yang-Mills theory in the limits of large Nc and large 't Hooft coupling. In particular, we study the theory at finite baryon number density. At zero temperature, we present an exact expression for the hypermultiplets' leading-order contribution to the free energy, and in the supergravity description we clarify which D-brane configuration is appropriate for any given value of the chemical potential. We find a second-order phase transition when the chemical potential equals the mass. At finite temperature, we present an exact expression for the hypermultiplets' leading-order contribution to the free energy at zero mass.Comment: 21 pages, 1 figure; v2 corrected typos, added comments to sections 2.2 and 2.

Working definitions, subjective and objective assessments and experimental paradigms in a study exploring social withdrawal in schizophrenia and Alzheimer's disease

Social withdrawal is one of the first and common signs of early social dysfunction in a number of important neuropsychiatric disorders, likely because of the enormous amount and complexity of brain processes required to initiate and maintain social relationships (Adolphs, 2009). The Psychiatric Ratings using Intermediate Stratified Markers (PRISM) project focusses on the shared and unique neurobiological basis of social withdrawal in schizophrenia, Alzheimer and depression. In this paper, we discuss the working definition of social withdrawal for this study and the selection of objective and subjective rating scales to assess social withdrawal chosen or adapted for this project. We also discuss the MRI and EEG paradigms selected to study the systems and neural circuitry thought to underlie social functioning and more particularly to be involved in social withdrawal in humans, such as the social perception and the social affiliation networks. A number of behavioral paradigms were selected to assess complementary aspects of social cognition. Also, a digital phenotyping method (a smartphone application) was chosen to obtain real-life data
