The Given

We study the structure of genetic coalgebras and prove the existence of a decomposition as the direct sum of indecomposable subcoalgebras with genetic realization. To obtain such a decomposition, we first define a new multiplication for their related cubic stochastic matrices of type (1,2) and then, considering these matrices as cubic non-negative, we show how this new multiplication induces an index classification which can be used to study the genetic coalgebra structure. Genetically, the given coalgebra decomposition can be understood as a genetic clustering of the different types for the genetic trait defining the genetic coalgebra, which allows us to identify isolated ancestral populations.

The Given

This paper is concerned with embodied processes of joint imagination in young children’s narrative interactions. Based on Karl Bühler’s notion of ‘deixis in the imagination’, it examines in detail how a 19-month-old German-speaking child, engaged in picture book reading with his mother, brings about different subtypes of deixis in the imagination by either ‘displacing’ what is absent into the given order of perception (e.g. by using the hand as a token for an object) or displacing his origo to an imagined space (e.g. by kinaesthetically aligning his body with an imagined body and animating his movements). Drawing on multimodal analysis and the concept of layering in interaction, the study analyses the ways in which the picture book as well as deictic, depictive, vocal and lexical resources are coordinated to evoke a narrative space, co-enact the storybook character’s experiences and produce reciprocal affect displays. Findings demonstrate that different types of displacement are in play quite early in childhood; displacements in the dimension of space and person are produced through layerings of spaces, voices and bodies.

Bacterial transformation and gene transfection can be understood as being the results of introducing specific genetic material into cells, resulting in gene expression, and adding a new genetic trait to the host cell. Many studies have been carried out to investigate different types of lipids and cationic polymers as promising nonviral vectors for DNA transfer. The present study aimed to carry out a systematic review on the use of biopolymeric materials as nonviral vectors. The methodology was carried out based on searches of scientific articles and applications for patents published or deposited from 2006 to 2020 in different databases for patents (EPO, USPTO, and INPI) and articles (Scopus, Web of Science, and Scielo). The results showed that there are some deposits of patents regarding the use of chitosan as a gene carrier. The 16 analyzed articles allowed us to infer that the use of biopolymers as nonviral vectors is limited due to the low diversity of biopolymers used for these purposes. It was also observed that the use of different materials as nonviral vectors is based on chemical structure modifications of the material, mainly by the addition of cationic groups. Thus, the use of biopolymers as nonviral vectors is still limited to only a few polysaccharide types, emphasizing the need for further studies involving the use of different biopolymers in processes of gene transfer.

Puzzling Problem ◽  
The Given

Abstract The telicity behavior of degree achievements has been a puzzling problem to many linguists. The most successful and currently standard theory (Kennedy & Levin 2008) treats them as degree expressions lexicalizing different types of scales, which in turn influence the resulting evaluative or non-evaluative interpretation. While it may account for English, this theory does not hold up cross-linguistically. We challenge the scalar theory with new Slavic data and show that verbal prefixes influence the (non-)evaluative interpretation of degree achievements more than their underlying scales do. This proposal is formalised as an addition of two type shifters, morphosyntactically realised as prefixes, which, in result, have an evaluative/non-evaluative effect on the given degree achievement.

Abstract The management of given and new information is one of the key components of accomplishing coherence in oral discourse, which is claimed to be a problematic area for language learners (Celce-Murcia, Dörnyei, and Thurrell 1995: 14). Research on discourse intonation proposes that instead of the given/new dichotomy, givenness should be viewed as a continuum, with different types of accessibility (Baumann & Grice 2006). Moreover, Prince (1992) previously categorized information structure into Hearer-old/Hearer-new and Discourse-old/Discourse-new information. There is consensus on the fact that focus or prominence associated with new information is marked with nuclear pitch accent, and its main acoustic cue, fundamental frequency (f0) (Ward & Birner 2001: 120). Non-native intonation has been reported to display numerous differences in f0 range and patterns compared to native speech (Wennerstrom 1994; Baker 2010). This study is an attempt to address the issue of marking information structure in existential there sentences by means of f0 in non-native spontaneous speech. Data originates from task-based interactions in the Wildcat Corpus of Native- and Foreign-Accented English (Van Engen et al. 2010). This paper examines two issues: (1) information structure in relation to the notions of givenness and different types of accessibility (Baumann & Grice 2006) and to Prince’s (1992) multidimensional taxonomy and (2) the use of f0 peaks to mark the prominence of new information. Several differences were measured among native speakers regarding the use of f0, sentence type, and complexity.

Pectin Substances

Viscosity is one of the characteristic properties of pectin substances, as well as other lyophilic colloids. Pectin molecules are easily associated with each other or with large molecules of related substances. This article contains the results of the study of dynamic viscosity, internal friction, thixotropic index of aqueous solutions (1 % and 4%) of various types of pectin substances and their combinations. The article presents the results of the study of the influence of different types of pectin substances and their combinations on the dynamic viscosity of pectin solutions and their internal friction. The analysis of values of dynamic viscosity and friction force depending on the type of pectin substances and their combinations is given. It is established that in cases where information on dissipative processes in pectin structures at low speeds and shear loads is required, it is necessary to rely on data on internal friction, in others - on the given information on their viscosity. The thixotropic index is calculated. It is established that the internal friction in pectin solutions and their dynamic viscosity depend on the type of pectin substances and their combinations. In pectin solutions, the internal friction is maximum for Apple pectin, and the dynamic viscosity – for a combination of citrus pectins with beet. When combining pectins, both indicators are most important for the combination of citrus with beet. The obtained data on the viscosity, internal friction and thixotropic index of solutions of different types and combinations of pectins make it possible to regulate the rheological properties of food systems with the addition of pectin substances.

The Euclidean plane and Euclidean space themselves do not contain imaginary elements by definition, but are inextricably linked with them through special cases, and this leads to the need to propagate geometry into the area of imaginary values. Such propagation, that is adding a plane or space, a field of imaginary coordinates to the field of real coordinates leads to various variants of spaces of different dimensions, depending on the given axiomatics. Earlier, in a number of papers, were shown examples for solving some urgent problems of geometry using imaginary geometric images [2, 9, 11, 13, 15]. In this paper are considered constructions of orthogonal and diametrical positions of circles on a complex plane. A generalization has been made of the proposition about a circle on the complex plane orthogonally intersecting three given spheres on the proposition about a sphere in the complex space orthogonally intersecting four given spheres. Studies have shown that the diametrical position of circles on the Euclidean E-plane is an attribute of the orthogonal position of the circles’ imaginary components on the pseudo-Euclidean M-plane. Real, imaginary and degenerated to a point circles have been involved in structures and considered, have been demonstrated these circles’ forms, properties and attributes of their orthogonal position. Has been presented the construction of radical axes and a radical center for circles of the same and different types. A propagation of 2D mutual orthogonal position of circles on 3D spheres has been made. In figures, dashed lines indicate imaginary elements.

If in an interval-valued intuitionistic fuzzy matrix each element is again a smaller interval-valued intuitionistic fuzzy matrix then the interval-valued intuitionistic fuzzy matrix is called interval-valued intuitionistic fuzzy partion matrix (IVIFPMs). In this paper, the concept of interval-valued intuitionistic fuzzy partion matrices (IVIFPMs) are introduced and defined different types of interval-valued intuitionistic fuzzy partion matrices (IVIFPMs). The operations like direct sum, Kronecker sum, Kronecker product of interval-valued intuitionistic fuzzy matrices are presented and shown that their resultant matrices are also interval-valued intuitionistic fuzzy partion matrices (IVIFPMs).

Workplace stress has always been considered as a potential source of job dissatisfaction and many psychosomatic disorders in employees the world over. The IT sector has emerged as a major contributor to work stress in India over the last 2 decades. Still there is lack of sector-specific studies, and most of the existing studies treat work stress as an umbrella term. Against this background, the objective of this article is twofold: one, to identify different types of stressors, and the other, to rate them according to their severity. The outcome should be helpful in devising proper mitigation strategies. On the basis of findings from the two field studies, the article identifies major stressors among junior level Indian IT professionals ( n1 = 38), and then furnishes a risk profile of these stressors on the basis of their frequency and impact ( n2 = 234). At the end, 21 stressors are identified in the given context, and their ‘riskiness’ is presented in a descending order in terms of risk scores. Implications of findings are discussed at the end. All the stressors were assigned a score in terms of their frequency, impact and risk. At the end, techno-stress emerged as the most serious stressor in both in terms of its frequency of occurrence and impact. The results serve as a guide to the management in the IT firms in addressing the prevalent high levels of stress at workplace. The risk scores will help them in allocating resources and, setting and prioritizing their HR strategies to this end. Amid few studies conducted in the context of stress in the Indian IT sector, this article offers useful and practical insights while deploying a novel approach of risk profiling.
