Room Temperature Instability of E′γ Centers Induced by γ Irradiation in Amorphous SiO2
2008
We study by optical absorption measurements the stability of E'(gamma) centers induced in amorphous silica at room temperature by gamma irradiation up to 79 kGy. A significant portion of the defects spontaneously decay after the end of irradiation, thus allowing the partial recovery of the transparency loss initially induced by irradiation. The decay kinetics observed after gamma irradiation with a 0.6 kGy dose closely resembles that measured after exposure to 2000 pulses of pulsed ultraviolet (4.7 eV) laser light of 40 mJ/cm(2) energy density per pulse. In this regime, annealing is ascribed to the reaction of the induced E'(gamma) centers with diffusing H(2) of radiolytic origin. At higher…
Innovative techniques for survey and communication of cultural heritage
2008
This paper deals with the survey and communications of Cultural Heritage through the development of innovative methodologies. The case of study is the polychrome wooden ceiling in the “Magna” Hall of “Palazzo Steri”. The “Steri”, built in the XIVth century by the noble family Chiaromonte, is at the present the headquarter of the Rector’s Office of Palermo University. A 3D model of the wooden ceiling has initially been carried out with laser-scanning and digital photogrammetric techniques; successively a multimodal interactive guide has been realized. The guide is integrated to the 3D model, so that visitors can navigate the virtual representation of the ancient wood ceiling and achieve, int…

Epistemic governance in local policy debates : The case of entitlement to early childhood education and care in Finland
2019
In Finland, children below school age have enjoyed the right to attend subsidised full-time early childhood education and care (ECEC). However, the attendance rate in Finland is low in comparison to other Nordic countries. Furthermore, the entitlement was restricted to 20 h per week in 2016 unless the child’s parents work or study full-time or unless it is believed that the child will benefit from full-time ECEC. The debates concerning restrictions in ECEC entitlement in three municipal councils serve as the data for this study. By using the framework of epistemic governance, we identify three differing constructions of the ECEC’s societal functions in the municipal policy debates. The simi…
On Conditions Instantiating Tip Effects of Epistemic and Evidential Meanings in Bulgarian
2012
Статья посвящена условиям, при которых происходит попеременная актуализация то эвиденциального, то эпистемического компонента в семантическом потенциале эвиденциальных показателей болгарского языка. Сосредоточиваясь на сентенциальных наречиях с инферентивными функциями, мы опираемся на следующие предпосылки: (i) для каждой единицы следует отличать её устойчивое семантическое значение от прагматического потенциала, выявлению которого способствуют (или препятствуют) те или иные коммуникативные условия; (ii) эвиденциальные и эпистемические компоненты значения довольно легко вытесняют друг друга из позиции доминанты, причём процесс подавления то одного, то другого компонента обусловлен действие…

Towards a lexicogrammatical pattern in Swedish crime novels
2013
The success of Swedish crime novels has been noted and discussed at length. Much of this commentary refers to a salient characteristic atmosphere which seems to be a common feature of most if not all Scandinavian crime novels. In this paper the potential of some recurring lexicogrammatical features to construct this characteristically gloomy and sombre atmosphere is presented and discussed. It will be shown that the vague feeling of unease which is perceived while reading these fictional texts is linguistically attestable. The analysis is conducted within the framework of M.A.K. Halliday’s systemic-functional grammar (SFG) which will be applied to three contemporary Swedish crime novels by …
Theresa May’s Representation of Reality in her Brexit Speeches
2020
This study analyses Theresa May’s three seminal Brexit speeches. These describe the kind of desirable post-Brexit EU-UK relationship that she envisioned, and together constitute a corpus of 18,532 words. The speeches can be considered as landmarks on a timeline that was initially meant to lead to the delivery of Brexit. It is hypothesized that there may be meaningful differences between the speeches, and that these affect the representation of reality. These in turn would have a bearing on May’s discursive self-representation as either an individualized or a collectivized social actor. To account for such representational values, the study draws on Halliday’s Transitivity System (1994), sta…
