Comments on: Games with a permission structure - A survey on generalizations and applications 2

In the field of cooperative games with restricted cooperation, various restrictions on coalition formation are studied. The most studied restrictions are those that arise from restricted communication and hierarchies. This survey discusses several models of hierarchy restrictions and their relation with communication restrictions. In the literature, there are results on game properties, Harsanyi dividends, core stability, and various solutions that generalize existing solutions for TU-games. In this survey, we mainly focus on axiomatizations of the Shapley value in different models of games with a hierarchically structured player set, and their applications. Not only do these axiomatizations provide insight in the Shapley value for these models, but also by considering the types of axioms that characterize the Shapley value, we learn more about different network structures. A central model of games with hierarchies is that of games with a permission structure where players in a cooperative transferable utility game are part of a permission structure in the sense that there are players that need permission from other players before they are allowed to cooperate. This permission structure is represented by a directed graph. Generalizations of this model are, for example, games on antimatroids, and games with a local permission structure. Besides discussing these generalizations, we briefly discuss some applications, in particular auction games and hierarchically structured firms

Social Environment and Genetics as Determinants of Depression Occurrence and Its Chronicity: A Longitudinal Survey

Depressive disorders are a set of heterogeneous disorders who se common characteristics are sadness and lack of interest, but varying regarding other symptoms, response to treatment and probability of recurrence and chronicity. They are a serious public health problem due to high prevalence and disability burden . Dep ression has a multifactorial causality with several genetic, behavioral and environmental factors playing a putative causal role . Thus, the aim of this thesis wa s to elucidate the interwoven effects of some environmental stressors, individual’s characteristics and some genetic factors on the occurrence and the course of depressive disorders. T he subjects were drawn from the PART study (In Swedish: Psykisk hälsa, A rbete och RelaTioner), a longitudinal study with three waves between 1998 and 2010, focused on mental health, work and relations among adult people residing in the Stockholm County, Sweden . In S tudies I and III, the relationship between polymorphisms in C OMT and serotonin transporter genes and depressive disorders were explored using a case - control approach. Ge ne x environment interaction effect s on depression risk were addressed focusing on COMT gene, childhood adversit ies and stressful life event s in Stu dy I ; and focusing on serotonin transporter gene and objective life events (i.e. loss/separation ) in Study III. Significant interactions were found between COMT and family problems during childhood and between serotonin transporter and partner’s loss/ separ ation. In Study II, the association between the psychosocial work environment and depression was scrutinized in a follow - up design of people employed in the same job over three - years . T he results showed a strong relationship between inadequate social climate and major depression among women three - years later , while there were no certain effects for the remaining exposure variables. Among men, the findings were controversial : high job demands and inadequate skill discretion appeared as protective factor s against depression ; thus, more studies using a similar approach are warranted. In Study IV, the complex inter - relationships among personal characteristics and circumstances over different life periods , and their effects on the chronicity of depression , were explored in a follow - up study of depressed subjects over ten years . It was analyzed using structural equation modeling (SEM). The resulting model revealed two main mechanisms anchored on personality traits: an internalizing pathway and an externalized /adversity pathway ; which are in line with studies about the onset of depression. The effort in this doctoral thesis consisted in putting together some pieces of a big puzzle. It is necessary to develop integrative models from different disciplines (e.g. genetics, neurosciences and epidemiology) in order to elucidate the complex mechanisms behind the depressive disorders

Comment on "A new approach of cooperative interval games: The interval core and Shapley value revisited"

The interval Shapley-like value for cooperative interval games was introduced by Han et al. (2012).A theorem of characterization of the interval Shapley-like value was provided in that paper. We show that there is an error in the proof of that theorem. We indicate how to avoid this error and complete the proof.Ministerio de Economía, Industria y Competitividad MTM2017-83455-

On the charged particle drag acting on LAGEOS

A recent study by the authors points to Charged Particle Drag (CPD) as a contributor to revisit in the LAGEOS non-gravitational perturbations problem. Such perturbations must account for dynamical contributions in the order of pms−2 . The simulated effect takes into account: (i) spatial and temporal variations of the plasmatic parameters (temperature and concentration of the species), (ii) spacecraft potential variations caused by both the eclipse passages and variations in the parameters mentioned above, and (iii) solar and geomagnetic conditions. Furthermore, recent theoretical improvements concerning scattering drag overcome previous limitations allowing for a complete formulation of this effect. For each satellite the lifetime CPD instantaneous acceleration is computed. The plasmatic parameters have been obtained fromthe Sheffield Coupled Thermosphere-Ionosphere-Plasmasphere (SCTIP) semi-empirical model (up to the polar region), as well as alytical/empirical approximations based on spacecraft measurements for the auroral and polar regions. Results show that maximum amplitudes for LAGEOSI are larger than those for LAGEOS-II: −85 pms−2 and −70 pms−2 respectively. This is due to the almost (magnetically) polar orbit configuration of the first, producing larger combinations of plasmatic parameter values. High solar activity has a huge impact in the resulting LAGEOS accelerations: it yields a perfect modulation of the resulting acceleration with maximum amplitudes up to a factor of 10 when comparing low and high activity periods. On the other hand, the impact of the geomagnetic activity results into a reduction of the effect itself, probably due to a decrease in the hydrogen concentration for high energy input periods. The acceleration results will be used in a refined orbit computation in a subsequent investigation

Vivero flotante solar de mejillón

En este proyecto elaboro el diseño de un prototipo de vivero flotante de mejillón que implementa paneles solares fotovoltaicos para generar energía eléctrica. El vivero o batea tendrá la misma operatividad que cualquier otra batea actualmente en funcionamiento para cultivar mejillón en las rías gallegas pero además dispondrá de una segunda función. Podrá producir energía eléctrica a través de una fuente renovable como es la solar que incide en gran medida en el lugar donde se encuentran ubicadas las bateas. Fue prioridad en el diseño que la ubicación de los paneles solares no dificulten en ningún caso el laboreo de los trabajadores en la batea, todo lo contrario, sino que podrán facilitar el movimiento de éstos sobre la misma. Los paneles instalados en el prototipo de batea solar que se presenta en este proyecto constan de una potencia de 270 Wp (vatios pico) sumando juntos una potencia instalada por batea de 12,96 kWp. También se estudiará la implantación de paneles solares fotovoltaicos a viveros flotantes ya existentes y en uso. Se determinará la producción energética del vivero y el potencial energético si se aplicase a más viveros flotantes en las rías gallegas. Se propondrá aplicación a la energía producida, tal como abastecer a núcleos urbanos cercanos. Por último, se realizará un análisis de rentabilidad económica.Traballo fin de grao (UDC.ETSNEM).

Cancer evolution and individual susceptibility

El pdf del artículo es la versión de autor.Cancer susceptibility is due to interactions between inherited genetic factors and exposure to environmental carcinogens. The genetic component is constituted mainly by weakly acting low-penetrance genetic variants that interact among themselves, as well as with the environment. These low susceptibility genes can be categorized into two main groups: one includes those that control intrinsic tumor cell activities (i.e. apoptosis, proliferation or DNA repair), and the other contains those that modulate the function of extrinsic tumor cell compartments (i.e. stroma, angiogenesis, or endocrine and immune systems). Genome-Wide Association Studies (GWAS) of human populations have identified numerous genetic loci linked with cancer risk and behavior, but nevertheless the major component of cancer heritability remains to be explained. One reason may be that GWAS cannot readily capture gene–gene or gene–environment interactions. Mouse model approaches offer an alternative or complementary strategy, because of our ability to control both the genetic and environmental components of risk. Recently developed genetic tools, including high-throughput technologies such as SNP, CGH and gene expression microarrays, have led to more powerful strategies for refining quantitative trait loci (QTL) and identifying the critical genes. In particular, the cross-species approaches will help to refine locations of QTLs, and reveal their genetic and environmental interactions. The identification of human tumor susceptibility genes and discovery of their roles in carcinogenesis will ultimately be important for the development of methods for prediction of risk, diagnosis, prevention and therapy for human cancers.J.

Neophobia and Seaweed Consumption: Effects on Consumer Attitude and Willingness to Consume Seaweed

[Abstract] Neophobia has become an increasingly researched phenomenon given its importance on the evaluation and acceptance of new products such as seaweeds, especially in a country where these products are not a part of the culinary tradition, for example, Spain. Seaweed is a form of algae, a nutritional and healthy product. Studies have investigated not only the influence of neophobia on the satisfaction and intention to consume seaweed, but also on its impact on the evaluation of the seaweed’s credence attributes such as health benefits. Previous research has concluded that consumers who are willing to consume novel products, like cooking and also demand elements of modernity and naturalness in their food. Considering this finding, a convenience sample comprising attendees of cooking workshops and young consumers was selected. Participants were evaluated about their opinion and attitude toward seaweed as food item, credibility of chefs, and the Food Neophobia Scale (FNS) prior to the tests. After the seaweed tasting, consumers were asked about their feedback and willingness to consume seaweed again. The results confirm that neophobia affects the intention to consume algae. However, consumer assessments of the credence attributes and confidence in the cues sent out by chefs regarding seaweed-based dishes are not influenced by neophobia. Hence, promotion of credence attributes such as health and natural properties of algae should be used to engage consumers potentially interested in new experiences. Simultaneously, the use of credible cues from chefs also represents an excellent way to increase consumer confidence and surpass the barrier created by neophobia

An Application of Cooperative Game Theory to Distributed Control

18th World CongressThe International Federation of Automatic ControlMilano (Italy) August 28 - September 2, 2011In this paper we propose to study the underlying properties of a given distributed control scheme in which a set of agents switch between different communication strategies that define which network links are used in order to regulate to the origin a set of unconstrained linear systems. The problems of how to decide the time-varying communication strategy, share the benefits/costs and detect which are the most critical links in the network are solved using tools from game theory. The proposed scheme is demonstrated through a simulation example
