Self-mention and uncertain communication in the British Medical Journal (1840\u20132007): The decrease of subjectivity uncertainty markers

The communication of a scientific finding as certain or uncertain largely determines whether that information will be translated into practice. In this study, a corpus of 80 articles published in the British Medical Journal for over 167 years (1840\u20132007) is analysed by focusing on three categories of uncertainty markers, which explicitly reveal a writer\u2019s subjectivity: (1) I/we epistemic verbs; (2) I/we modal verbs; and (3) epistemic non-verbs conveying personal opinions. The quantitative analysis shows their progressive decrease over time, which can be due to several variables, including the evolution of medical knowledge and practice, changes in medical research and within the scientific community, and more stringent guidelines for the scientific writing (regarding types of articles, their structure and rhetorical style)

Duality Symmetries and G^{+++} Theories

We show that the non-linear realisations of all the very extended algebras G^{+++}, except the B and C series which we do not consider, contain fields corresponding to all possible duality symmetries of the on-shell degrees of freedom of these theories. This result also holds for G_2^{+++} and we argue that the non-linear realisation of this algebra accounts precisely for the form fields present in the corresponding supersymmetric theory. We also find a simple necessary condition for the roots to belong to a G^{+++} algebra.Comment: 35 pages. v2: 2 appendices added, other minor corrections. v3: tables corrected, other minor changes, one appendix added, refs. added.

Generalised geometry, eleven dimensions and E11

We construct the non-linear realisation of E11 and its first fundamental representation in eleven dimensions at low levels. The fields depend on the usual coordinates of space-time as well as two form and five form coordinates. We derive the terms in the dynamics that contain the three form and six form fields and show that when we restricted their field dependence to be only on the usual space-time we recover the correct self-duality relation. Should this result generalise to the gravity fields then the non-linear realisation is an extension of the maximal supergravity theory, as previously conjectured. We also comment on the connections between the different approaches to generalised geometry.Comment: 17 pages, Trivial typos corrected in version one and a substantial note added which gives the equation of motion relating the gravity field to its dua

The third transitional Identity of migrant adolescents. The case of Hotel House an Italian multi-ethnic skyscraper-ghetto

The adolescent\u2019s identity achievement is a complex task, even more so if they are migrants living in a particular context of ethnic ghettoization. Hotel House is an enormous, isolated condominium situated on the outskirts of Porto Recanati, a small Italian town. It is a unique reality poorly studied from a social psychological perspective. The present paper aims to measure the perceived levels of self-concept clarity, self-determination, ethnic group identification, relationship with parents, depression and life satisfaction in a group of 91 adolescents (11\u201319 years; 30% females; 1.5 immigrant\u2019s generation) living in this context. The analysis shows low levels of self-concept clarity and self-determination, especially in female adolescents, quite satisfactory relationships with their parents and medium levels of group identification and life satisfaction. The identification with their ethnic subgroups seems to provide a third transitional identity which works as a temporary link between native country values and host country values. The regression analysis shows significant associations: self-determination is negatively associated with depression and positively associated with the perception of life satisfaction; the father\u2019s closeness is a negative predictor for depression and a positive predictor for life satisfaction; mother\u2019s closeness is negatively associated with depression

D-Brane Wess-Zumino Terms and U-Duality

We construct gauge-invariant and U-duality covariant expressions for Wess-Zumino terms corresponding to general Dp-branes (for any p<D) in arbitrary 2<D<11 dimensions. A distinguishing feature of these Wess-Zumino terms is that they contain twice as many scalars as the 10-D compactified dimensions, in line with doubled geometry. We find that for D<10 the charges of the higher-dimensional branes can all be expressed as products of the 0-brane charges, which include the D0-brane and the NS-NS 0-brane charges. We give the general expressions for these charges and show how they determine the non-trivial conjugacy class to which some of the higher-dimensional D-branes belong.Comment: 42 pages.

\u201cOld Wine in a New Bottle\u201d. Depression and Romantic Relationships in Italian Emerging Adulthood: The Moderating Effect of Gender

Intimate partner violence is an important social issue all over the world, and human sciences, in particular, are working to reduce it. Despite this, the topic is a little recognized phenomenon. Understanding the origins and the variables that have an impact on manic-style romantic relationships, as defined by John Alan Lee, is of primary importance, in particular in Italy where the data reveal alarming statistics. Most studies have not controlled for earlier depressive symptoms as a cause of successive depression or as an antecedent of romantic styles. In our study, we investigate the association between depression and romantic style, trying to test the moderating role of the gender variable in 283 Italian emerging adults (139 women and 144 men). In order to achieve this aim, we performed a multigroup structural equation model analysis. The hypothesis that gender moderates the relationship between depression and romantic styles is still yet to be confirmed. Men with high levels of depression do not seem to be able to establish relationships based on commitment, as required by the eros style. Women with high levels of depression are more frequently involved in possessive and demanding relationships or in pragmatic ones, confirming their need for dependence

E11, generalised space-time and equations of motion in four dimensions

We construct the non-linear realisation of the semi-direct product of E11 and its first fundamental representation at low levels in four dimensions. We include the fields for gravity, the scalars and the gauge fields as well as the duals of these fields. The generalised space-time, upon which the fields depend, consists of the usual coordinates of four dimensional space-time and Lorentz scalar coordinates which belong to the 56-dimensional representation of E7. We demand that the equations of motion are first order in derivatives of the generalised space-time and then show that they are essentially uniquely determined by the properties of the E11 Kac-Moody algebra and its first fundamental representation. The two lowest equations correctly describe the equations of motion of the scalars and the gauge fields once one takes the fields to depend only on the usual four dimensional space-time
