Discrete Bright-dark Soliton Interaction Dynamic Behaviors for Nonautonomous 2+1-Dimensional Soliton Equation

The non-autonomous discrete bright-dark soliton solutions(NDBDSSs) of the 2+1-dimensional Ablowitz-Ladik(AL) equation are derived. We analyze the dynamic behaviors and interactions of the obtained 2+1-dimensional NDBDSSs. In this paper, we present two kinds of different methods to control the 2+1-dimensional NDBDSSs. In first method, we can only control the wave propagations through the spatial part, since the time function has not effect in the phase part. In second method, we can control the wave propagations through both the spatial and temporal parts. The different propagation phenomena can also be produced through two kinds of managements. We obtain the novel "л"-shape non-autonomous discrete bright soliton solution(NDBSS), the novel "λ"-shape non-autonomous discrete dark soliton solution(NDDSS) and their interaction behaviors. The novel behaviors are considered analytically, which can be applied to the electrical and optical fields.

From engaging publics to engaging knowledges: Enacting “appropriateness” in the Austrian biobank infrastructure

While there is consensus on the essential importance of public engagement in further developments of biobanking, the related investigation of public views predominantly focused on the concerns expressed by the publics, and the concrete formats of public engagement, without delving into the ways these concerns are constituted. In this article, we summarize recent research on public engagement in order to describe the constitution of respective concerns as “engagement of knowledges.” By shifting the focus of analysis from “publics” to “knowledges,” we draw attention to the interaction dynamic through which citizens embed the new knowledge they receive during expert interactions into the stock of knowledge they already possess. Analyzing our recent investigation of public views on biobanking in the form of citizen-expert panels in the Austrian infrastructure of biobanks (BBMRI.at), we trace this dynamic through citizens’ recurrent concerns that the research and consent practices related to biobanking should be “appropriate.”

Temporality of sense-making in narrative interactions

Human experience is inherently temporal and involves placing events, symbols, and actions in a temporal scheme. This article deals with a specific aspect of temporal experience as it relates to reading and experiencing narrative fiction. Within an enactive understanding of human cognition, we propose a view of literary reading as a process of participatory sense-making between a reader and a storyteller. The enactive theory of participatory sense-making maintains that agents, by enacting their own sense-making, directly and partially constitute the sense-making of other agents. Sense-makers in interaction navigate two orders of normativity: their own and that of the interaction itself. Linguistic sense-making (languaging) opens up further possibilities for understanding complex spatially and temporally distributed forms of social interactions such as narrative interactions. Reading a narrative is one such example of mutually constituted navigation between an interaction dynamic and interactors’ sense-making. The reader completes and co-authors emergent textual meaning and a textually emerging storyteller guides and anticipates the multiple temporal displacements, realized linguistically, that a reader has to experience in the process of reading. We explore the participatory structure of a narrative through its temporal unfolding and the specific, non-linear nature of the temporal dynamics of interacting with a storytelling agency. In particular, narrative interactions are seen as modulations in the pacing of a given narrative’s unfolding. It is suggested that the reader’s enactment of such temporally realized pacings constitutes a better description of narrative immersion than its traditional understanding as a simulation of spatial situatedness.

Effect of the age of ganders on reproductive behavior and fertility in a competitive mating structure

This paper presents the study on determination of gander-goose mating activity in relation to age and the position of gander in social hierarchic rank. Moreover, levels of fertility (F) and testosterone (T) in different gander age groups were analyzed. The study was carried out on one-year-old geese (N = 64) and one- or two-year-old ganders (N = 16; 1♂: 4♀). Observations of mating activity (MA) were conducted during the 3-h period of the daylight (10 h), 2-3 times per week (102 h/ group/34 days). The recording was done with a digital recorder connected to cameras. Agonistic behavioral interactions between ganders were noted to determine a social hierarchic rank. The MA was described by frequency of courtship displays, copulation attempts, successful copulation (SCop), and interaction disrupted (DMI) with agonistic behavior. Fertility was evaluated after the artificial incubation (1×/week) in a commercial hatchery. The frequency of SCop, DMI, and T concentration were higher (P<0.05) for two- than one-year-old ganders. Moreover, F was higher by 11.2% for group of geese kept with two-year-old ganders. There was an effect of the gander’s rank in social hierarchy on the frequency of MA. For dominant ganders, frequency of courtship displays (1.0/times/3 h) and copulation attempts (0.8/times/3 h) were lower (P<0.05), but SCop (1.5/times/3 h) was higher (P<0.05) than for subordinate ones. Thus, in domestic goose flocks reproductive success was associated with age of ganders used in competitive mating system. This is probably a multifactor effect of interaction between sexual/social experience, T-dependent mating motivation, and efficiency of MA. It is recommended to keep one-year-old geese with older ganders (after sexual reactivation) for optimal fertility results with sex ratio adjusted to gander-gander antagonistic interaction dynamic.
