This paper is a response to articles in the literature regarding symbols in dreams. While some neurology-based dream studies reject dream symbols altogether, the preponderance of material available for review accepts that dreams are frequently populated by symbols that require interpretation to be understood. In this study of my own extensive dream journals, the presence of veridical psi dreams makes it possible to rule out symbolic content in some cases. The results of this study show that-at least from the 11,850 dream scenes reviewed here-unambiguous symbolic content is extremely rare. For this paper, it was assumed that no dreams contained any symbolically presented information unless the dreams contained unambiguous indications that symbols were present. Following this method, a distinction may be made between dream content that clearly contains symbols and dreams that are assumed to be symbolic by default. Symbols that met the criteria used here can be shown to be di?erent from conventionally accepted symbols in that they clarify-rather than obfuscate-the communication of complex ideas.

For delayed and long-term students, the education process is often a lonely journey. The main conclusion of this research is that learning should not be an individual process of the student connected to one lecturer, but rather a community where learning is a collective journey. The social interaction between lecturers, groups of delayed students and other actors is an important engine for arriving at the new knowledge, insights and expertise that are important to reach their final level. This calls for the design of social structures and the collaboration mechanism that enable the bonding of all members in the community. By making use of this added value, new opportunities for the individual are created that can lead to study success. Another important conclusion is that in the design and development of learning communities, sufficient attention must be paid to cultural characteristics. Students who delay are faced with a loss of self-efficacy and feelings of shame and guilt. A learning community for delayed students requires a culture in which students can turn this experience into an experience of self-confidence, hope and optimism. This requires that the education system pays attention to language use, symbols and rituals to realise this turn. The model ‘Building blocks of a learning environment for long-term students’ contains elements that contribute to the study success of delayed and long-term students. It is the challenge for every education programme to use it in an appropriate way within its own educational context. Each department will have to explore for themselves how these elements can be translated into the actions, language, symbols and rituals that are suitable for their own target group.

Reading and writing is modelled in CSP using actions containing the sym- bols ? and !. These reading and writing actions are synchronous and there is a one- to-one relationship between occurrences of pairs of these actions. It is cumbersome to ease the restriction of synchronous execution of the read and write actions. For this reason we introduce the half-asynchronous parallel operator that acts on actions con- taining the symbols ¿ and ¡ and study the impact on a Vertex Removing Synchronised Product.

Reading and writing is modelled in CSP using actions containing the symbols ? and !. These reading actions and writing actions are synchronous, and there is a one-to-one relationship between occurrences of pairs of these actions. In the CPA conference 2016, we introduced the half-synchronous alphabetised parallel operator X ⇓ Y , which disconnects the writing to and reading from a channel in time. We introduce in this paper an extension of X ⇓ Y , where the definition of X ⇓ Y is relaxed; the reading processes are divided into sets which are set-wise asynchronous, but intra-set-wise synchronous, giving full flexibility to the asynchronous writes and reads. Furthermore, we allow multiple writers to the same channel and we study the impact on a Vertex Removing Synchronised Product. The advantages we accomplish are that the extension of X ⇓ Y gives more flexibility by indexing the reading actions and allowing multiple write actions to the same channel. Furthermore, the extension of X ⇓Y reduces the end-to-end processing time of the processor or coprocessor in a distributed computing system. We show the effects of these advantages in a case study describing a Controlled Emergency Stop for a processor-coprocessor combination.

In this paper, we experimentally compare orthogonal frequency-division multiplexing (OFDM) and on-off keying (OOK) modulation in the context of the IEEE 802.15.13-2023 standard at bandwidths up to 50 MHz across a Li-Fi link with distances up to 5 m and a lateral offset up to 51°. Error vector magnitude (EVM) and bit error rate (BER) evaluations confirm that the high peak-to-average power ratio (PAPR) of OFDM limits the achievable transmission distance, but it offers higher data rates due to its higher spectral efficiency. Due to the lower PAPR, OOK-based Pulsed Modulation PHY (PM-PHY) shows a significantly higher link range. As the structure of the PM-PHY is based on OFDM symbols, the two solutions may also be combined to open a wider range of use cases for optical wireless communications.

Reading and writing is modelled in CSP using actions containing the symbols ? and !. These reading actions and writing actions are synchronous, and there is a one-to-one relationship between occurrences of pairs of these actions. In the CPA conference 2017, we introduced the extended half-synchronous al- phabetised parallel operator X ⇕ Y , which disconnects the writing to and reading from a channel in time; the reading processes are divided into sets which are set-wise asynchronous, but intra-set-wise synchronous, giving full flexibility to the reads. In this paper, we allow multiple writers to write to the same channel set-wise asynchronously, but intra-set-wise synchronously and we study the impact on our (Extended) Vertex Removing Synchronised Product. The advantages we accomplish are that the extension of X ⇕ Y gives more flexibility by indexing the writing actions and the reading actions, leading to a straightforward majority vote design. Furthermore, the extension of X ⇕ Y preserves the advantages of the X ⇕ Y operator.

In Amsterdam and Beirut, Abdallah has ethnographically researched interactional dynamics between disadvantaged young people, regarding experiences of success, in settings of education, work, sports, and music. He analyzed how focus, mood, and bodily deployment produced shared symbols, emotional contagions, and situated solidarities and moralities.He came to characterize constructive interactions as a main context for young people to experience three components of success: boosts, elevation, and grounding. Combinations of these experiences have important restorative effects for young people who suffer from an abundance of adversity and discouragement. Tensions arise for young people between, on the one hand, their loyalties toward old settings of belonging with their short-term, at times destructive, tendencies and, on the other hand, their success in new settings which demanded of them new types of discipline and commitments. Continued success depends partly on young people’s abilities, but more so on the availability of constructive interaction rituals helping them manage such tensions, without necessarily committing to one loyalty over the other. Next to young people’ s dynamics and processes, Abdallah has focused on the input of NGO professionals and volunteers in such constructive interactions to learn how their involvement can help young people in their struggles for success.The analysis employs concepts of sociological studies of emotions, such as interaction rituals, emotion management, and embodied dispositions to clarify how emotion, experience and energy act as driving forces in young people’s activities and development.

Conceptual metaphors play a vital role in our ability to think in abstract terms like knowledge. Metaphors structure and give meaning to the concept of knowledge. They hide and highlight certain characteristics. The choice of metaphor when reasoning about knowledge is therefore of vital importance for knowledge management (KM). This paper explores the possibility of introducing new knowledge metaphors to the field of KM. Based on a ‘wish list’ of characteristics of knowledge they want to highlight, the authors choose to explore the Knowledge as a Journey metaphor as a new metaphor for knowledge. This results in new insights regarding knowledge sharing, acquisition, retention, and innovation.
