After World War 2, rickets had disappeared from the U.K. Then in 1960, 19 consecutive cases were reported from Guy's Hospital. A little later, Gavin Arneil discovered cases of rickets in Glasgow. Half of these cases were among non‐British children, but although many of these were coloured, they also included Irish and Spanish children. This showed that lack of skin pigment does not necessarily protect children against rickets.

As conviviality can nurture community social capital, this paper aims to investigate how such capital can give rise to economic behaviour in terms of developing business relationships.

The empirical analysis was based on case studies of Italian businesses recognised as active communities that periodically organise convivial activities to fuel reciprocal collaboration. The case studies were constructed by combining a collection of secondary data, in-depth interviews and participant observations.

This paper shows how: community social capital in convivium emerges from self-narrative stimulated by ritual practices; social trust mobilising a convivial social capital is fuelled by knowledge generated through sharing and empathic relationships; community-based social relations embed business relations and if mediated, community-based business relations can also embed a community business.

The originality of the paper is twofold as it contributes: to understanding how conviviality can be used as a strategic tool for entrepreneurs to develop business relationships from convivial relations; and to finding intersection points between studies on business relationships from social capital and studies on entrepreneurship from community social capital.

The purpose of this paper is to introduce an approach for m‐valued classical and non‐classical (reversible and quantum) optical computing. The developed approach utilizes new multiplexer‐based optical devices and circuits within switch logic to perform the required optical computing. The implementation of the new optical devices and circuits in the optical regular logic synthesis using new lattice and systolic architectures is introduced, and the extensions to quantum optical computing are also presented.

The new linear optical circuits and systems utilize coherent light beams to perform the functionality of the basic logic multiplexer. The 2‐to‐1 multiplexer is a basic building block in switch logic, where in switch logic a logic circuit is implemented as a combination of switches rather than a combination of logic gates as in the gate logic, which proves to be less‐costly in synthesizing wide variety of logic circuits and systems. The extensions to quantum optical computing using photon spins and the collision of Manakov solitons are also presented.

New circuits for the optical realizations of m‐valued classical and reversible logic functions are introduced. Optical computing extensions to linear quantum computing using photon spins and nonlinear quantum computing using Manakov solitons are also presented. Three new multiplexer‐based linear optical devices are introduced that utilize the properties of frequency, polarization and incident angle that are associated with any light‐matter interaction. The hierarchical implementation of the new optical primitives is used to synthesize regular optical reversible circuits such as the m‐valued regular optical reversible lattice and systolic circuits. The concept of parallel optical processing of an array of input laser beams using the new multiplexer‐based optical devices is also introduced. The design of regular quantum optical systems using regular quantum lattice and systolic circuits is introduced. New graph‐based quantum optical representations using various types of quantum decision trees are also presented to efficiently represent quantum optical circuits and systems.

The introduced methods for classical and non‐classical (reversible and quantum) optical regular circuits and systems are new and interesting for the design of several future technologies that require optimal design specifications such as super‐high speed, minimum power consumption and minimum size such as in quantum computing and nanotechnology.

The purpose of this paper is to introduce new non‐classical implementations of neural networks (NNs). The developed implementations are performed in the quantum, nano, and optical domains to perform the required neural computing. The various implementations of the new NNs utilizing the introduced architectures are presented, and their extensions for the utilization in the non‐classical neural‐systolic networks are also introduced.

The introduced neural circuits utilize recent findings in the quantum, nano, and optical fields to implement the functionality of the basic NN. This includes the techniques of many‐valued quantum computing (MVQC), carbon nanotubes (CNT), and linear optics. The extensions of implementations to non‐classical neural‐systolic networks using the introduced neural‐systolic architectures are also presented.

Novel NN implementations are introduced in this paper. NN implementation using the general scheme of MVQC is presented. The proposed method uses the many‐valued quantum orthonormal computational basis states to implement such computations. Physical implementation of quantum computing (QC) is performed by controlling the potential to yield specific wavefunction as a result of solving the Schrödinger equation that governs the dynamics in the quantum domain. The CNT‐based implementation of logic NNs is also introduced. New implementations of logic NNs are also introduced that utilize new linear optical circuits which use coherent light beams to perform the functionality of the basic logic multiplexer by utilizing the properties of frequency, polarization, and incident angle. The implementations of non‐classical neural‐systolic networks using the introduced quantum, nano, and optical neural architectures are also presented.

The introduced NN implementations form new important directions in the NN realizations using the newly emerging technologies. Since the new quantum and optical implementations have the advantages of very high‐speed and low‐power consumption, and the nano implementation exists in very compact space where CNT‐based field effect transistor switches reliably using much less power than a silicon‐based device, the introduced implementations for non‐classical neural computation are new and interesting for the design in future technologies that require the optimal design specifications of super‐high speed, minimum power consumption, and minimum size, such as in low‐power control of autonomous robots, adiabatic low‐power very‐large‐scale integration circuit design for signal processing applications, QC, and nanotechnology.

In this project, we propose and test a new device – wearable sociometric badges containing small microphones – as a low-cost and relatively unobtrusive tool for measuring stress response to group processes. Specifically, we investigate whether voice pitch, measured using the microphone of the sociometric badge, is associated with physiological stress response to group processes.

We collect data in a laboratory setting using participants engaged in two types of small-group interactions: a social interaction and a problem-solving task. We examine the association between voice pitch (measured by fundamental frequency of the participant’s speech) and physiological stress response (measured using salivary cortisol) in these two types of small-group interactions.

We find that in the social task, participants who exhibit a stress response have a statistically significant greater deviation in voice pitch (from their overall average voice pitch) than those who do not exhibit a stress response. In the problem-solving task, participants who exhibit a stress response also have a greater deviation in voice pitch than those who do not exhibit a stress response, however, in this case, the results are only marginally significant. In both tasks, among participants who exhibited a stress response, we find a statistically significant correlation between physiological stress response and deviation in voice pitch.

We conclude that wearable microphones have the potential to serve as cheap and unobtrusive tools for measuring stress response to group processes.

The internationalization of education introduces notable cross-cultural challenges and benefits for consideration by scholars of comparative and international education. When teachers move overseas to work, they become sojourners, “between-society culture travelers” (Ward et al., 2005, p. 6). Living and working between cultures offers a substantial set of both challenges and opportunities. Acculturation theory (Sam & Berry, 2006) was initially understood as culture shock (Oberg, 1960), an occupational malady. Acculturation theory seeks to explain adaptation processes and has mostly examined sojourners whose intent is to permanently adapt to a new culture. Educators who are sojourners require temporary states of adaptation. This chapter narrates a subset of a qualitative study examining educator acculturation from an asset orientation to explore what benefits acculturation offers to sojourning educators who work in international schools overseas. Findings include that even highly stressful episodes of culture shock can manifest in long-term benefits, such as the development of personal and professional resilience and self-leadership strategies, as well as the reflective curating of one’s personal and professional identity, which may include the development of an interstitial identity. These benefits serve to increase educators’ cultural competencies, to prepare educators for supporting sojourning students who are acculturating, and to prepare educators for smoother acculturation experiences afterwards.

Noting the recent wave of books on business and spirituality, the editor of a business journal recently sardonically observed that there must be more Zen in American boardrooms than in Buddhist monasteries. While the spirituality of business may be withering, the business of spirituality appears only too alive. Elmer Gantry has left the revivalist tents and entered the convention hall circuit of motivational speakers and corporate awards banquets.
