Quantum criticality of CeLaRuSi : the magnetically ordered phase
We report specific heat and neutron scattering experiments performed on the
system CeLaRuSi on the magnetic side of its quantum
critical phase diagram. The Kondo temperature does not vanish at the quantum
phase transition and elastic scattering indicates a gradual localisation of the
magnetism when increases in the ordered phase.Comment: To be published in the proceedings of QCNP0
Artificial scaling laws of the dynamical magnetic susceptibility in heavy-fermion systems
We report here how artificial, thus erroneous, scaling laws of the dynamical
magnetic susceptibility can be obtained when data are not treated carefully. We
consider the example of the heavy-fermion system
CeLaRuSi and we explain how different kinds of
artificial scaling laws in can be plotted in a low temperature
regime where the dynamical susceptibility is nearly temperature independent.Comment: 4 pages, 4 figure
Y a-t-il une voie au-delà du positivisme ? Les approches critiques et le débat épistémologique en relations internationales
Cet article examine le dĂ©bat Ă©pistĂ©mologique en relations internationales (ri) et les critiques Ă lâendroit du positivisme. Il avance que les approches critiques ne parviennent pas Ă prĂ©ciser suffisamment quel est le problĂšme du positivisme. On ne sait jamais Ă quoi pourrait ressembler une Ă©pistĂ©mologie postpositiviste. Ce texte met lâemphase sur la contribution des poststructuralistes en montrant comment le rĂŽle central de la diffĂ©rence dans la construction du sens explique pourquoi nos thĂ©ories sont toujours indĂ©pendantes du monde quâelles analysent, sans toutefois ĂȘtre arbitraires. Il sâĂ©loigne cependant de la stratĂ©gie de la dĂ©construction, en affirmant que reconnaĂźtre le rĂŽle que joue la diffĂ©rence au niveau Ă©pistĂ©mologique offre un terrain sur lequel peut sâĂ©riger une nouvelle forme de rigueur analytique que nous qualifions ici de critique.This paper surveys the epistemological debate in International Relations and reassesses criticisms of positivism. Critical approaches have often failed to specify the problem of positivism. It thus remains unclear whether there is a path beyond it. This article focuses on the poststructuralist contribution to this debate, which comes closer to correctly identifying why positivism reifies international relations. Indeed, poststructuralists have correctly identified how the role of difference in the construction of meaning illustrates why our theories are always independant from the world they supposedly describe, although not arbitrary. The article moves away from deconstruction and argues that recognizing the centrality of difference can instead offer a field on which to conceptualize a new form of analytical and critical rigour
Macro-finance and the financialisation of economic policy
Reflecting on the broad ambitions of macro-finance, I argue that the commitment to placing finance at the centre of our economic conceptions comes with significant risks that speak directly to the politics of financialisation. By redirecting the focus of economic governance towards finance, macro-finance may consolidate rather than challenge the problematic trends of global finance. More specifically, I argue that the focus of the money view on liquidity has contributed to depoliticising financial governance and aligning it further with the demands of financialisation
Explaining enhanced logical consistency during decision making in autism
The emotional responses elicited by the way options are framed often results in lack of logical consistency in human decision making. In this study, we investigated subjects with autism spectrum disorder (ASD) using a financial task in which the monetary prospects were presented as either loss or gain. We report both behavioral evidence that ASD subjects show a reduced susceptibility to the framing effect and psycho-physiological evidence that they fail to incorporate emotional context into the decision-making process. On this basis, we suggest that this insensitivity to contextual frame, although enhancing choice consistency in ASD, may also underpin core deficits in this disorder. These data highlight both benefits and costs arising from multiple decision processes in human cognition
Patient capital in the age of financialized managerialism
This article focuses on the history of financialized management and its connections to shareholder value, which is often viewed as undermining patient strategies of investments. We argue that the rise of financialized management has in fact a long history that goes back to the conglomerate movement in 1960s America. As we show, the conglomerates pioneered the use of financial markets as a baseline for strategy, and the emphasis on financial transactions as an engine for growth. They developed key techniquesâhigh leverage, share-price maximization and accounting manipulationâthat later came to be associated with managerial strategies of the shareholder value era. This legacy has important implications for how we think about patient capital. It challenges the idea that patient capital consists foremost in shielding non-financial companies from capital markets and highlights the central role of management too often neglected in these debates
Values in middle childhood: Social and genetic contributions
Theories of value development often identify adolescence as the period for value formation, and cultural and familial factors as the sources for value priorities. However, recent research suggests that value priorities can be observed as early as in middle childhood, and several studies, including one on preadolescents (Knafo & Spinath, 2011), have suggested a genetic contribution to individual differences in values. In the current study, 174 pairs of monozygotic and dizygotic 7-year old Israeli twins completed the Picture-Based Value Survey for Children (PBVSâC; Döring et al., 2010). We replicated basic patterns of relations between value priorities and variables of socialisation â gender, religiosity, and socioeconomic statusâ that have been found in studies with adults. Most important, values of Self-transcendence, Self-enhancement, and Conservation, were found to be significantly affected by genetic factors (29%, 47% and 31% respectively), as well as non-shared environment (71%, 53% and 69% respectively). Openness to change values, in contrast, were found to be unaffected by genetic factors at this age and were influenced by shared (19%) and non-shared (81%) environment. These findings support the recent view that values are formed at earlier ages than had been assumed previously, and they further our understanding of the genetic and environmental factors involved in value formation at young ages
