Rus v Comcare: The Rules of Evidence in the AAT

The Rus v Comcare cases arise from a claim for compensation by the widowed Ms Rus. The cases saw a highly contentious piece of evidence tendered. This evidence was hearsay of a lay opinion that answered the ultimate issue. The evidence was considered by the Administrative Appeals Tribunal (‘AAT’) and the Federal Court of Australia (‘Court’). These considerations demonstrate the uncertainty of how the rules of evidence are applicable in tribunals. Specifically, the cases raise applicability of the rules against opinion and hearsay evidence. Further, the relevance of delay and the parol evidence rule to these cases is raised. The principles and policies governing these issues are analysed, which warranted minimal if any discussion in the cases, to assist practitioners in similar cases

Searches for new physics using dijet events at the LHC

We present a concise review of the plans of the ATLAS and CMS collaborations to search for new physics using dijet events. The inclusive cross section as a function of jet p$_{T}$, the dijet mass distribution and the dijet ratio's CMS techniques are presented together with their potential of discovery with a focus on the integrated luminosities of 10, 100 and 1000 pb$^{-1}$. Analogously, the inclusive jet and angular distribution searches in the dijet channel from ATLAS are presented together with the potential of discovery given in terms of needed integrated luminosity.Comment: Talk given at the "Rencontres de Moriond" QCD 200

Development and Maintenance of Self-Disclosure on Facebook: The Role of Personality Traits

This study explored the relationships between Facebook self-disclosure and personality traits in a sample of Italian users. The aim was to analyze the predictive role of Big Five personality traits on different parameters of breadth and depth of selfdisclosed behaviors online. Facebook users, aged between 18 and 64 years of age (Mage = 25.3 years, SD = 6.8; N = 958), of which 51% were female, voluntarily completed an online survey assessing personality traits and Facebook self-disclosure. Results at a series of hierarchical regression analyses significantly corroborated the hypotheses that high extroverted and openness people tend to disclose on Facebook a significant amount of personal information, whereas high consciousness and agreeableness users are less inclined to do it. Furthermore, more extroverts and agreeableness people develop less intimacy on Facebook, differently from those with high levels of openness. Results also corroborated the hypothesis of a full mediation of time usage in the relationship between personality factors such as extroversion and conscientiousness with breadth of Facebook self-disclosure. Overall, according to the findings of the current study, personality traits and Facebook self-disclosure become central both as predictive variables for depicting the different profiles of potential addicted and as variables to help educators, teachers, and clinicians to develop training or therapeutic programs aimed at preventing the risk of Internet addiction. Limitations of the study are discussed, and directions for future research are suggested

Flux tubes in the SU(3) vacuum

We analyze the distribution of the chromoelectric field generated by a static quark-antiquark pair in the SU(3) vacuum. We find that the transverse profile of the flux tube resembles the dual version of the Abrikosov vortex field distribution and give an estimate of the London penetration length in the confined vacuum.Comment: 7 pages, 3 figures, poster contribution to the XXIX International Symposium on Lattice Field Theory, LATTICE 201

Integrated Methodologies for the Analysis and Conservation of the Old Bar (Montenegro): the Case Study of Doge’s Palace

The old town of Bar in Montenegro, a Byzantine settlement rebuilt on the remains of a more ancient town destroyed in the 3rd century during the Roman invasion of Dalmatia, ruled between 1443 and 1571 from the city of Venice and then by the Turks until 1878 is, today, a little over an abandoned village but, at the same time, an extraordinary monument from the past to protect and enhance. Traces of its most glorious past are still recognizable in the ruins and artifacts of daily life become known following recent archaeological excavations. Stari Bar is a site unique, a sort of miracle that fortunately survived the ravages of time and negligence of the men. However, it now runs the risk of being overwhelmed by a frenzy of "intervention" that leaves little room for reflection and that can produce errors, which cannot be remedied in the future. Rather than rebuild a fake medieval city or give way to immobility, risking that the culture of ruin prevail, it is necessary to pursue activities of knowledge, study and promotion allowing local communities (as well as those further afield) to re-appropriate the memory of those architectural and urban spaces, triggering new ideas for their possible regeneration. In this framework, this paper presents the case study of the "Doge's Palace", analyzing this important monument in depth knowledge, in order to formulate a proposal for its conservation and valorisation. The experience here reported responds to the initial phase of a more ambitious project aiming at producing a three dimensional “picture” of the site in its current state: a representation made both through the documentation of the town’s most relevant parts and the use of virtual tours and 3D modelling. This activity intends to support the nomination proposal submitted by Montenegro in 2010 to include Stari Bar in UNESCO’s World Heritage List

A study for the conservation of the architectural Islamic complex of Xhemal in Delvina (Albania)

Water is a fundamental element for Islamic culture and the need to purify themselves before the prayer and religious celebrations is made in special baths - near mosques - called hammam. The hammam is usually a large public service building, but there are particular types of small dimensions and for the exclusive use of a wealthy family or, as in the case study here presented - related to the Islamic complex of Xhemal in Delvina (Albania) - an integral part of a religious centre. Characterised by a singular complexity, the monumental site of Xhemal is composed of some aboveground tombs, a mosque, a tekke, two türbe, a fountain and a hammam indeed, as well as of ancient tall plants (cypresses and plane trees). The building, already listed by the national Institute for Cultural Monuments of Albania, has been the subject of a study carried out by prof. Valter Shtylla at the end of the 70s and classed as a hammam from the medieval period. Provisionally measured only in its plan, it is today in a state of serious deterioration, while an example of great interest. For this reason and, along with the entire complex, since 2008 it has been an object of study by the University of Bergamo and Enna Kore, within the research group formed by the Milan Polytechnic and the University Ca' Foscari, in the framework of the program “Albania tomorrow” co-funded by the Cariplo Foundation, in collaboration with the municipality of Delvina. The complex has recently been subjected to a complete laser scanning survey in order to develop a well-planned preservation and valorisation programme

Metallicity evolution of AGNs from UV emission-lines based on a new index

We analyzed the evolution of the metallicity of the gas with the redshift for a sample of AGNs in a very wide redshift range (0<z<4) using ultraviolet emission-lines from the narrow-line regions (NLRs) and photoionization models. The new index C43=log(CIV+CIII])/HeII is suggested as a metallicity indicator for AGNs. Based on this indicator, we confirmed the no metallicity evolution of NLRs with the redshift pointed out by previous works. We found that metallicity of AGNs shows similar evolution than the one predicted by cosmic semi-analytic models of galaxy formation set within the Cold Dark Matter merging hierarchy (for z < 3). Our results predict a mean metallicity for local objects in agreement with the solar value (12+log(O/H)=8.69). This value is about the same that the maximum oxygen abundance value derived for the central parts of local spiral galaxies. Very low metallicity log(Z/Z_{\odot})~ -0.8 for some objects in the range 1.5 < z <3 is derived.Comment: 25 pages, 10 figures, accepted MNRA

High velocity blue-shifted FeII absorption in the dwarf star-forming galaxy PHL293B: Evidence for a wind driven supershell?

X-shooter and ISIS WHT spectra of the starforming galaxy PHL 293B also known as A2228-00 and SDSS J223036.79-000636.9 are presented in this paper. We find broad (FWHM = 1000km/s) and very broad (FWZI = 4000km/s) components in the Balmer lines, narrow absorption components in the Balmer series blueshifted by 800km/s, previously undetected FeII multiplet (42) absorptions also blueshifted by 800km/s, IR CaII triplet stellar absorptions consistent with [Fe/H] < -2.0 and no broad components or blushifted absorptions in the HeI lines. Based on historical records, we found no optical variability at the 5 sigma level of 0.02 mag between 2005 and 2013 and no optical variability at the level of 0.1mag for the past 24 years. The lack of variability rules out transient phenomena like luminous blue variables or SN IIn as the origin of the blue shifted absorptions of HI and FeII. The evidence points to either a young and dense expanding supershell or a stationary cooling wind, in both cases driven by the young cluster wind.Comment: Accepted for publication in MNRAS; 15 pages, 10 figure

Sulphur abundance determinations in star-forming regions-I: Ionization Correction Factor

In the present work we used a grid of photoionization models combined with stellar population synthesis models to derive reliable Ionization Correction Factors (ICFs) for the sulphur in star-forming regions. These models cover a large range of nebular parameters and yielding ionic abundances in consonance with those derived through optical and infrared observational data of star-forming regions. From our theoretical ICFs, we suggested an {\alpha} value of 3.27 in the classical Stasinska formulae. We compared the total sulphur abundance in the gas phase of a large sample of objects by using our Theoretical ICF and other approaches. In average, the differences between the determinations via the use of the different ICFs considered are similar to the uncertainties in the S/H estimations. Nevertheless, we noted that for some objects it could reach up to about 0.3 dex for the low metallicity regime. Despite of the large scatter of the points, we found a trend of S/O ratio to decrease with the metallicity, independently of the ICF used to compute the sulphur total abundance.Comment: Accepted for publication in MNRAS, 21 pages, 8 figures, 5 table

The Italian version of the Thinking About Life Experiences Questionnaire and its relationship with gender, age, and life events on Facebook

The present study provided a cross-cultural validation of the Thinking About Life Experiences Scale-revised (TALE-R) in an Italian sample of Facebook users (n = 492; female = 378; male = 114; mean age 26.1) to test for replication and universality of the TALE-R three-factor model. Furthermore, it explored the interrelations among gender, age, the scores at the TALE-R and the frequency of posting textual/visual information about individuals' life events on Facebook. Results at exploratory and confirmatory factor analysis gave empirical support to both of a tripartite model for the functions of autobiographical memory (i.e., directive-behavior, social-bonding, and self-continuity) and measurement invariance of this three-factor model across gender and age. Further results at linear correlation and regression analyses showed that directive-behavior and self-continuity functions of autobiographical memory are significantly related to the ways people use Facebook for personal documentation. Age differences more than gender influence this association. Discussion and conclusion reported both theoretical and empirical implications of the findings of the study
