Complex Dynamic Systems

Accurate assessment of team performance in complex, dynamic systems is difficult, particularly teamwork such as Crew Resource Management (CRM) in aircraft. Seventy pilots from two fleets were evaluated as two-person crews by a Maneuver Validation (MV), which focused on proficiency on separate maneuvers, and by a Line Operational Evaluation (LOE), which focused on the crew flying a simulated line flight. Instructor/Evaluator (I/E) pilots helped design LOE content and a structured evaluation worksheet. I/E reliability training resulted in high evaluator agreement (average rwg = .80) and acceptable inter-rater correlations (average r = .54). Path analysis supported the assessment flow from Observable Behaviors to Technical and CRM performance to Captain (PIC), First Officer (SIC), and Crew evaluations for each event set. Fleet evaluations were different on the LOE assessment, but equivalent on the MV assessment. Detailed analysis of assessments also indicated a different role of the SIC across fleets. One fleet assessed SIC more on CRM performance and weighted SIC performance more in evaluating Crew performance. The other fleet assessed SIC on technical performance and weighted SIC performance less in evaluating Crew performance.

L1 English

The aim of this study is to investigate the effect of familiarity with Brazilian-accented English (L2) in the intelligibility of speech samples when judged by native English listeners. Speech samples were collected from five native Brazilian Portuguese individuals from Southern Brazil, with a pre-intermediate level of proficiency in English. Following a Complex Dynamic Systems account (De Bot et al., 2007), this is a longitudinal study in which a group of four British listeners participated in weekly intelligibility transcription tasks, applied over the course of five weeks. This group was comprised of individuals who had recently arrived in Brazil. Results suggest that familiarity with a speaker’s L1 and accented-L2 has an effect on the intelligibility of what is heard. From the perspective of Complex Dynamic Systems, we argue that there is an alteration of a listener’s perception of his/her own language system due to exposure to it as an L2.

The article is aimed at outlining the functions of the theory of the effectiveness of systems (in particular, enterprises) by essence, as well as substantiating the role of indicators of components of effectiveness therein under modern conditions of system development. The article covers some issues of the theory and philosophy of the effectiveness of the functioning of enterprises as systems on the basis of SEE-management as a means of improving the effectiveness of the processes of functioning of complex systems in the context of definitions of «quantity/quality» based on the measurement and assessment of the components of the above-mentioned effectiveness using the criterion of progressive effectiveness. The results of computations according to the models of indicators of components of effectiveness, taking into account the values of the criterion of progressive effectiveness, can contribute to the choice of the appropriate strategy for the development (behavior) of the enterprise (active, passive, active-passive, etc.). It is emphasized that SEE-management, which is based on the author’s concepts of components of effectiveness, is a means of increasing the effectiveness of the functioning of complex dynamic systems (by which we will understand the set of its subprocesses) taking into account risks in the context of the negative impact of the external environment, in particular local and global crises in the economy. The scientific novelty of the results of author’s content analysis and applied explorations of the author for more than 20 years is the description of the essence of axiological and other functions of the theory of effectiveness, as well as the addition of methodological functions of this theory with indicators of constituent effectiveness, which can facilitate the improvement of the management of systems of different types and hierarchical levels. The above indicated management can be carried out using such a modern approach as author’s SEE-management, for the implementation of which certain indicators are presented and the appropriate managerial SEE actions in cases of different situations with respect to various values of performance indicators is proposed.

Abstract Notion

The 40th anniversary of the Journal of Language and Social Psychology occurs around the corner of another anniversary, the language motivation field reaching 60 years. At this occasion, we pause to reflect on the contribution of language motivation research to language teaching practice. We argue that this contribution has been negligible and put forward two main reasons. The first is related to an identity crisis in the language motivation field, falling at the intersection of applied linguistics, education, and psychology; the second is the marginalization of the role of context. To address these issues, we first present insights from two perspectives—sociocultural theory and complex dynamic systems theory—and then propose three solutions to incorporate these insights: (1) moving from the abstract notion of “motivation” to the more tangible construct of “engagement”, (2) encouraging rigorous transdisciplinary research, and (3) taking advantage of the potential of artificial intelligence to translate research findings into practice.

L2 Development

In this plenary address, I suggest that Complexity Theory has the potential to contribute a transdisciplinary theme to applied linguistics. Transdisciplinary themes supersede disciplines and spur new kinds of creative activity (Halliday 2001 [1990]). Investigating complex systems requires researchers to pay attention to system dynamics. Since applied linguists study language systems that change (for example, as they develop in learners, this is a useful perspective to bring to bear on many of our concerns. To introduce Complexity Theory, I list twelve principles undergirding this perspective and elaborate on three of them: those to do with dynamism, complexity, and the role of context. I then discuss several studies of L2 development that have been informed by the perspective. I conclude by suggesting that the ultimate promise of Complexity Theory is the help it provides in humanizing science.

Composite Properties

The possibility of increasing crack resistance, strength and elastic modulus of polymer-containing compositions due to the directed organization of their structure by internal, external and complex activation is investigated. Filled polymer compositions are presented as open complex dynamic systems. This made it possible to use rational fillers and special matrix-transformer of external electromagnetic influences as factors for controlling the processes of their structure formation and hardening to obtain materials with the required properties.
