AbstractWhile motile bacteria display rich dynamics in dense colonies, the phoretic nature of artificial micro-swimmers restricts their activity when crowded. Here we introduce a new class of synthetic micro-swimmers that are driven solely by light. By coupling a light absorbing particle to a fluid droplet we produce a colloidal chimera that transforms optical power into propulsive thermo-capillary action. The swimmers’ internal drive allows them to operate for a long duration (days) and remain active when crowded, forming a high density fluid phase. We find that above a critical concentration, swimmers form a long lived crowded state that displays internal dynamics. When passive particles are introduced, the dense swimmer phase can re-arrange to spontaneously corral the passive particles. We derive a geometrical, depletion-like condition for corralling by identifying the role the passive particles play in controlling the effective concentration of the micro-swimmers.

The current challenge for the survival and growth of companies is the appropriation of innovation in all its senses, the generation of propitiate resilient environments, the innovation philosophy acquisition into action, and improve internal dynamics and cohesion through a comparison of leadership styles oriented by the motivation to serve as a servant leadership. This chapter analyses the relevance of the culturally intelligent organizations to carry out innovation. Likewise, the styles of servant leadership and administration that generate a collective consciousness tend to create innovation and more resilient environments.

This chapter builds on the assertion that spirituality is best understood as one dimension of the larger phenomenon of lived religious practice, rather than as a phenomenon separate from or opposed to religion. Spirituality is situated in a multidimensional analysis that also includes embodiment, materiality, emotion, aesthetics, morality, and narrative. By analyzing spirituality as a distinct dimension of religious practice, we can see the internal dynamics among all the dimensions. Understanding spirituality and religion at this micro level is incomplete, however, without attention to the distinct legal and cultural contexts around the world. This chapter elaborates on four ideal-typical macrosocial contexts that each shape quite differently the practice of religion and its spiritual dimensions: entangled, established, institutionalized, and interstitial contexts. These contexts identify differences in modal expectations for the fields within which religious practices will be found and the modes of regulation that will constrain religious action.

The juvenile nature of the criminal offence perpetrator, due to its psychophysical characteristics, makes the phase of execution of criminal sanctions additionally delicate and very important and implies a system of execution based on special principles and special organization. The aim of this paper is to analyze the activities of the competent guardianship authorities, both in the phase of issuing educational orders and educational measures, and in the phase of their execution. The paper emphasizes that the realization of the "internal dynamics" of the system of educational measures, from the choice of a concrete measure to its suppression, with all intermediate modalities of cumulation, replacement and adjustment to changed execution conditions or achieved success, is made possible to the competent court through the cooperation with guardianship authorities. It is precisely in the field of application of educational measures, as the basic type of criminal sanctions for juvenile offenders, that the exceptional connection of the juvenile criminal justice system with the social protection system is most clearly seen.

This paper examines how a systems sensing—or felt-sense—approach and orientation to inquiry and systemic constellation practice might help social change organizations cultivate capacities to better navigate complexity, both in their outer-facing work and internal dynamics as teams and as individuals. We present a pilot study of systemic constellation practice, sharing the experience of participants during and after the practice, as well as our own reflexive process. Currently an undertheorized and underutilized approach within systems thinking work, systems sensing and systemic constellation, can reveal less visible but nevertheless foundational dynamics at play in an organizational body, and can help create more awareness through widening ways of knowing in the organizational playground. We explore how the facilitated collective sense-making process of systemic constellation engages subtle ways of knowing specifically energetic, relational, and embodied knowing, building on what Heron and Reason (2008) have called an “extended epistemology.” As we suggest, these more subtle ways of knowing warrant further study, particularly as they may contribute to action research methods and foster a more participatory culture of transformation at both an organizational and societal level.

Abstract. Fragmented aurora-like emissions (FAEs) are small (few kilometres) optical structures which have been observed close to the poleward boundary of the aurora from the high-latitude location of Svalbard (magnetic latitude 75.3 ∘N). The FAEs are only visible in certain emissions, and their shape has no magnetic-field-aligned component, suggesting that they are not caused by energetic particle precipitation and are, therefore, not aurora in the normal sense of the word. The FAEs sometimes form wave-like structures parallel to an auroral arc, with regular spacing between each FAE. They drift at a constant speed and exhibit internal dynamics moving at a faster speed than the envelope structure. The formation mechanism of FAEs is currently unknown. We present an analysis of high-resolution optical observations of FAEs made during two separate events. Based on their appearance and dynamics, we make the assumption that the FAEs are a signature of a dispersive wave in the lower E-region ionosphere, co-located with enhanced electron and ion temperatures detected by incoherent scatter radar. Their drift speed (group speed) is found to be 580–700 m s−1, and the speed of their internal dynamics (phase speed) is found to be 2200–2500 m s−1, both for an assumed altitude of 100 km. The speeds are similar for both events which are observed during different auroral conditions. We consider two possible waves which could produce the FAEs, i.e. electrostatic ion cyclotron waves (EIC) and Farley–Buneman waves, and find that the observations could be consistent with either wave under certain assumptions. In the case of EIC waves, the FAEs must be located at an altitude above about 140 km, and our measured speeds scaled accordingly. In the case of Farley–Buneman waves a very strong electric field of about 365 mV m−1 is required to produce the observed speeds of the FAEs; such a strong electric field may be a requirement for FAEs to occur.
