The risk management business evolves rapidly, so actuaries are faced with the need for new analysis methodologies. However, the use of incorrect methodologies for actuarial modeling can have serious implications for strategic decision making. This study aims to introduce the simplex regression model as a suitable methodology for actuarial modeling of data whose values belong to the unit interval. Using a risk management data set, the linear model with normal distribution and the proposed regression model were compared. The evaluation of the models presented concluded by the quality of the modeling through simplex regression, indicating the quality of this method as a new analysis tool for the actuarial context.

The article proposes an analysis of the guitar piece Kurze Schatten II by Brian Ferneyhough. The analysis aims to understand the compositional procedures and aesthetic principles of the composer, revealing an approximation with concepts from the thought of Gilles Deleuze, Felix Guattari and T. Adorno. By understanding the elements that manage the internal logic of the work, it is evident that the composer's serialist heritage, developed in the light of the Adornian concept of informal music, is present in the structural components of Kurze Schatten II and in the processuality of the creative gesture. The rupture with the traditional concept of unity perceived in the analysis originates a music of transformations, passages, approximations and contrasts, realized in a rhizomatic space operated by differences and impermanences. The technical analysis of the work brings to the forefront issues that are better understood in the light of these considerations of aesthetic order.

Our paper conducts a contrastive analysis between Albanian and English lexical units in the language of laws using corpora analysis. It fills a literature gap related to Corpus linguistics in order to better comprehend patterns of legal lexicon. We use KWIC Concordance to extract the top frequently words and concordance lines in order to analyse differences and similarities among lexical units in Albanian (Source Language) and English (Target Language) laws, compared to those identified in respective corpora. Additionally, we identify types of errors in translation, difficulties in translating legal texts, and factors that influence translators’ errors in translating certain laws of the Republic of Kosovo from Albanian into English. According to our analysis, both languages have in common the use of the same grammatical patterns such as: conjunctions, prepositions, and the use of the common noun forms. The rest have significant differences in their usage, especially with regards to particles and determiners. Our contrastive approach demonstrates that some of these laws were not originally written in Albanian and then translated into English language, as many articles within these laws lack the appropriate word structure and word order and in some cases are semantically ill-formed in the Source Language. Key words: analysis, corpus, language, legal, translation, KWIC Concordance.

This study investigates the composition and corrosion of a lead ossuary excavated from the archaeological cemetery located on the site of the Queen Alia International Airport, Jordan. It also presents its conservation treatment using the potentiostatic reduction method. X-ray fluorescence (XRF) and scanning electron microscopy/ energy dispersive X–ray spectroscopy (SEM/EDX) analyses showed that the ossuary was made from a relatively pure lead metal. Examination of the corrosion products using X–ray diffraction (XRD) and SEM/EDX analyses indicated the presence oxides, carbonates and chlorides of lead as the main corrosion products on the ossuary. The metallographic examination showed a cast α-Pb dendritic microstructure. A linear sweep voltammetry (LSV) scan for a small fragment from the ossuary in a sodium sulfate solution allowed identifying the working conditions to reduce the corrosion products to lead metal. Chronoamperometry (CA) techniques helped to monitor the reduction process and determine its completion. The potentiostatic methods showed an excellent effectiveness in determining treatment parameters and monitoring the reduction process of the corrosion products on the ossuary and to prevent over-treatment. The reduced ossuary was finally coated with Paraloid B72 to prevent corrosion reoccurrence in the poor environmental conditions of the storage area.

Through a selection of essays, the volume provides an overview on forms of symmetry in music, analysed from a mathematical and physical perspective. The idea of translating nine essays on this topic from English to Italian can be interpreted as a laudable attempt at making them immediately usable outside the scientific domain. The first section, ‘Musicological Perspectives’, has a ‘literary’ approach and proposes different readings of music history through the filter of as many meanings of the concept of symmetry. The second, ‘Mathematical and Physical Perspectives’, has a specifically scientific approach and essentially elaborates models for the representation and visualization of the principles that are implict in musical structures, or analyzes the physical-acoustic properties of the sound object, highlighting symmetry factors in a more or less explicit way.

THE STATE OF THE ART OF VOLATILE CARBONYL COMPOUNDS IN INTERNAL ENVIRONMENTS: IMPACTS TO HEALTH AND SAMPLING METHODOLOGIES AND ANALYSIS. The primary sources of emission of volatile carbonyl compounds (CCs) in indoor environments are chipboard panels, laminate floors, plywood, paints and solvents, household products, fiberglass, gas stoves, heaters and heating systems. Several studies have already confirmed an indoor/outdoor (I/O) ratio greater than 1 (one) for several CCs, indicating that these compounds are emitted mainly from internal sources. CCs (especially aldehydes and ketones) are easily absorbed into the airways, presenting a considerable mutagenic, teratogenic and carcinogenic risk to humans. Therefore, this study aimed to review the CCs found in different indoor environments, the effects and impacts of these compounds on human health and the national and international guidelines that establish their maximum exposure limits. The methodologies most used in the literature to analyze CCs in the air were reviewed directly (in real-time) or indirectly (using pre-treatment steps). A detailed review of the sampling techniques: with and without adsorption, with and without derivatization, with adsorption and derivatization simultaneously; using various methodologies employed during the last decades (cartridges, filters, tubes or liquid absorbent-impinger) was carried out. Finally, this work describes the instrumental methods and the advantages and disadvantages of determining CCs individually and simultaneously in the atmosphere.

Most assessment instruments in Music Therapy need to have their effectiveness proven, directing interventions in a manner consistent with the needs of individuals. Based on the relations inferred between musical language and written language, and studies on musical intervention in dyslexia, it could be hypothesized that children identified at risk of dyslexia could present some impairment in the “Cognition” domain of IMTAP, which evaluates the largest number of constructs similar to the items evaluated in psychological instruments. Therefore, this paper investigated whether a series of activities created to assess the “Cognition” domain of the IMTAP protocol was related to a battery encompassed by psychological instruments normally used in cognitive assessment of reading. The expectations of the study were not confirmed. Pearson's correlations, although significant, were very low, suggesting that the constructs evaluated by IMTAP are different from the constructs of the other tests used.

Objective: To analyze the response to retreatment in patients with chronic/episodic migraine who discontinued therapy with erenumab/fremanezumab after one year of treatment., Methods: Observational, retrospective, single-center, multidisciplinary study in patients with chronic/episodic migraine who received therapy with erenumab/fremanezumab for at least one year and discontinued it after achieving an adequate response (optimization). The evaluation of the response after retreatment included the following variables: migraine days per month, MIDAS and HIT-6 scales at the beginning of retreatment and 3 months later. The response was evaluated in different subgroups (episodic/chronic, erenumab/fremanezumab and time until retreatment)., Results: 48 patients were included. 70.8% (n=34) required retreatment with mAb, with a median of 3.9 (2.9-6.4) months until reintroduction. Clinical response after retreatment was achieved in 67.6% (n=23) of patients. No statistically significant differences were found in the analyzed subgroups., Conclusion: Interruption of treatment with erenumab/fremanezumab for chronic/episodic migraine produces a clinical worsening of the disease requiring retreatment in most cases, approximately after 4 months. Two out of three patients respond positively after restarting monoclonal therapy. This response does not appear to be related to the type of migraine, the specific monoclonal antibody prescribed, or the time to retreatment., (Copyright © 2024.

The purpose of this research is to identify, from the application of analytical strands, how Franz Liszt (1811-1886) materializes the mermaid myth in his Lied Der Fischerknabe, about the writer's text Friedrich Schiller (1759-1805). The bibliographic survey reveals that Liszt is historically remembered for his exacerbated virtuosity and his contribution to the evolutionary path that harmony would follow in later decades; However, he is neglected as a songwriter by his contemporaries, such as Schubert, Schumann, Wolf and Brahms. In Der Fischerknabe, Liszt traces an intimate relationship between text and music, linking the subjective images of poetry to its harmonic language, melodic conduction, modulatory character, accompanying figuration, and constant tonal contrasts, thus presenting literary-musical images linked to the myth of the mermaid. It was concluded that the lyricism and the symbiosis between text and music reached by Liszt in this Lied approach the consecrated procedures of other geniuses related to the genre.

The objective was to evaluate some physical properties of the soil in four suburban farms in Santiago de Cuba. Soil samples were taken and the volumetric weight, apparent density, real density, porosity and humidity were determined. Among the farms, a similar statistical behavior of the evaluated properties was obtained. The volumetric weight varied from 1.18 to 1.32 g cm-3, the apparent density between 1.04 and 1.24 g cm-3, the real density from 2.27 to 2.59 g cm-3, the porosity ranged from 51 to 53 % and the humidity from 6.1 to 11.4 %.

There are multiple communicative strategies in architecture depending on the target audience. The mechanisms of representation may radically vary when the recipient is the client, the constructor, the curator, a colleague or even an instructor (1). As an example, the approach may be mainly visual when the target is the client. However, it may be strictly structural to start a conversation with a peer ad mostly conceptual when pointing to the jury members in a competition. In certain cases, the adaptation of the graphic language to the different scenarios leads to such a distortion on the message that the original project is hardly recognizable. To illustrate this point, the article will focus on the project of the Public Seattle Library, designed by the architect Rem Koolhaas. The analysis of five different communicative strategies of the project show peculiar and unequal graphic narrations: from the concept book of the competition, the website of LMN (the American partners of Rem Koolhaas- OMA in this particular project), the website of OMA, the coverage on the Seattle press, the Library Brochure for teenagers and the approach developed on the "Content" book. Rem Koolhaas coined the concept of "design of information" to express the fundamental relationship between the message and media in architecture. In his practice, the communicative strategy is present from the beginning of the design process till the final stages. In this article, the thoughtful comparison of these examples will enable to extract conclusions on the use of communication in architectural design and reflect on the iconic and communicative dimension of architecture in general.
