An analysis of Bayesian estimates for missing higher orders in perturbative calculations

With current high precision collider data, the reliable estimation of theoretical uncertainties due to missing higher orders (MHOs) in perturbation theory has become a pressing issue for collider phenomenology. Traditionally, the size of the MHOs is estimated through scale variation, a simple but ad hoc method without probabilistic interpretation. Bayesian approaches provide a compelling alternative to estimate the size of the MHOs, but it is not clear how to interpret the perturbative scales, like the factorisation and renormalisation scales, in a Bayesian framework. Recently, it was proposed that the scales can be incorporated as hidden parameters into a Bayesian model. In this paper, we thoroughly scrutinise Bayesian approaches to MHO estimation and systematically study the performance of different models on an extensive set of high-order calculations. We extend the framework in two significant ways. First, we define a new model that allows for asymmetric probability distributions. Second, we introduce a prescription to incorporate information on perturbative scales without interpreting them as hidden model parameters. We clarify how the two scale prescriptions bias the result towards specific scale choice, and we discuss and compare different Bayesian MHO estimates among themselves and to the traditional scale variation approach. Finally, we provide a practical prescription of how existing perturbative results at the standard scale variation points can be converted to 68%/95% credibility intervals in the Bayesian approach using the new public code MiHO.

Variation of word-forming means in modern Russian: traditions and innovations

The author considers the conditions necessary to discern variable means of forming lexical units. The aim of the paper is to identify the rising trends which characterise variation in the sphere of word formation in the modern Russian language. These trends are described analysing the traditional criteria which determine the potentiality of varied morphemic division and identifying the means of word formation. The employed research methods included observation and description, morphemic and word-formation analysis, classification and systematisation. The material of the study is the derived lexemes obtained from contemporary media and advertising texts. The author describes the factors determining the possibility of employing the variation approach to identify ways of word formation. Additionally, new trends which broaden the sphere of derivational phenomena and undermine the entire derivational system of the Russian language are examined.

‘Ou ni right-la pou remain silans’

Although in recent years researchers have intensified focus on the communication of the pre-trial right to silence or police caution to native and non-native speakers of English, most of this research has been concerned with linguistic complexity, comprehension, and comprehensibility issues. Relatively few studies have focused attention on the role played by the deliverer of the caution in the communicative equation (Cotterill 2000), particularly in situations where the caution has to be interpreted or translated by its deliverer. Drawing on a sociolinguistic variation approach, this study investigates the communication of the police caution to creole speakers, who remain nearly invisible in the research to date. It uses the categories of literal and free translation as tools to analyze spontaneous translations of the caution from English to French lexicon Creole (Kwéyòl) produced by (n = 25) police officers in St. Lucia. The results show considerable variability in these translations, which may have negative consequences for the accused. This study seeks to draw attention to these consequences, by underscoring some of the inaccuracies that may occur in translating or interpreting a caution written in English to Kwéyòl, and make a case for policy that would use the language of the accused in situations of language variation. The study argues that such a policy, which standardizes the Kwéyòl version of the caution, would not only obviate the potential for variability, but would also minimize misunderstandings, which could compromise the legal rights of the suspect.

Receptive Arts Engagement for Health: A Holistic and Trans-Disciplinary Approach to Creating a Multisensory Environment

Multisensory environments are increasingly being used in health care settings with reported benefits including relaxation, supporting self-regulation, enhancing mood, and reducing chronic pain. However, limited research exists that explores the impact of multisensory environment design on engagement. In response, this article presents a qualitative study exploring the creative design attributes that cultivated participant engagement and shaped their overall experience of spending time in an artistically created multisensory environment: the Sensory-Art Space (SAS). A maximum variation approach to sampling was used to select 18 participants. Data were gathered via semi-structured interviews and were audio-recorded and transcribed verbatim before being analyzed thematically. Our findings produced three key themes. The first two themes were: the ambience of everything and variation: it’s always my choice, which identified aspects of the artistic design that fostered engagement and the sense of connection and ownership of the SAS captured in the third theme, a space that’s yours. Based on analysis of participant responses, creative design considerations were identified that could assist the development of future multisensory spaces and highlighted the importance of a holistic and curatorial approach to enhance engagement value.
