Semantic Overlaps Between Chinese Two-Character Words and Constituent Characters: A Normative Study

In written Chinese, the graphic units are Chinese characters (CCs). Most of the commonly used characters often join with others to form two-character words (2C-words) or words of more than two characters. Indeed, over 70% of the commonly used words are 2C-words. Since almost all characters are meaningful in their own right, there are semantic overlaps between 2C-words and their constituent characters. The present study investigated how normative semantic overlap of 2C-words and their constituent characters (SWC) might be influenced by whether the constituent characters are word or word-not characters (Wording) and by whether they are left or right characters (Positioning) and might be predicted by ordinary features of the constituent characters. The results confirmed earlier work that word-not characters are more strongly associated than word characters with 2C-words, and that right characters are more strongly than left characters associated with the 2C-words in semantics. The present study is also the first to provide evidence concerning the prediction of SWC by the norm features of the constituent characters. Skilled readers’ perception of the semantic features, frequency features and number-of-word features of the constituent characters may be mediated by Wording and Positioning in 2C-word semantic processing. However, they are not likely to perceive the visual features of the constituent characters. Rather, they seem to take the constituent characters of m-CCs as individual units, which should be highly familiar to them. In a semantic task on 2C-words, skilled readers may process the constituent characters in number of meanings, concreteness, imageability and emotion arousal, but not in sensory experience arousal. There appears to be a close association in valence between the 2C-words and the word characters, but not between the 2C-words and the word-not characters. These findings strongly support the theoretical argument that both words and characters should be taken as language units in Chinese. However, Wording and Positioning should be considered carefully when considering a CC as a language unit. These findings may be of more general significance for semantic understanding of compound words.

“…The activities carried out by NASA in the US also are on the same page, as indicated in the results of the projects AGATE [4] and SATS [5]- [6]. In order to make viable, also economically, the exploitation on a wider scale of SAT vehicles, nevertheless, the implementation of Single Pilot Operations (SPOs) is needed for such business domain, which in turn requires dedicated technological automation improvements on-board, such as the availability of advanced self-separation and advanced collision avoidance on-board equipment, making use of ADS-B (Automatic Dependent Surveillance -Broadcast) and GNSS (Global Navigation Satellite System) data, and the availability of automatic pilot incapacitation management systems on-board, in order to manage also not-nominal operational conditions in a safe way [7]- [8]. For instance, in [9] it is clearly emphasized that additional advanced automation tools are required to recover from pilot incapacitation in general, a data-link outage or breakup, as well as a coincidence of both events together.…”

The paper describes research and development activities under Clean Sky 2 Cost optimized Avionic System (COAST) program. The main goal of this development was to deliver technology enablers at TRL 5 for affordable cockpit and avionics. The target segment for the technology enablers is aircraft with 1 to 19 passengers and small cargo aircraft belonging to CS-23 category. The main aim is to provide overall summer during the whole COAST program development per individual technology. Sections are divided per each technology with their results and overall contribution to the program. The Clean Sky 2 COAST program covered the development of following technologies: Cockpit Architecture SAT avionic system architecture, Flight Management Tactical Separation System (TSS), Advanced Weather Awareness System (AWAS), Flight Reconfiguration System (FRS), Navigation and Surveillance Dual Frequency Multi-Constellation GNSS Receiver (GNSS), Low-cost Integrated Navigation System (NAV), Affordable Integrated Surveillance System (SURV), Platform technologies Compact Computing Platform (CCP), High Integrity Electronics for health monitoring (HIE), Integrated Mission Management System Integrated Mission Management System (IMMS). These technologies were part of several flight test campaigns which took place in the Czech Republic with Evektor company using EV-55 aircraft.

Advanced avionics and automation technologies have significantly transformed cockpit operations, resulting in a gradual reduction of the crew members on-board. Single-pilot operations (SPO) concept is gaining significant attention in the aviation industry due to its potential for cost savings and to cope with the anticipated pilot shortage and the increasing air traffic demand. This paper conducts a scoping literature review on SPOs, serving as an initial step to map the scientific peer-reviewed content on the subject. The survey focuses on three thematic domains, which are, respectively, operations, automation, and the emerging field of digital and cognitive flight assistants. The methodology involved the use of Google Scholar and IEEE Xplore databases. Sources were selected adapting the search criteria to the proposed sub-topics and prioritizing either the most cited and recent contributions. The analysis of the literature reveals a growing body of work in the recent years. This review also highlights interest in the human-centered design for automation solutions which are responsive to cognitive and behavioral states of the pilot. While acknowledging the potential safety and operational challenges associated with SPOs and the pilot-automation cooperation, this work suggests that great research efforts should be made on the human factor and regulatory subjects to pave the way for a feasible and safe implementation of the single-pilot paradigm in commercial aviation.
