CO2-laser optical lattice with cold rubidium atoms
No full textLaser-cooled rubidium atoms have been trapped in a nondissipative optical lattice with a large lattice constant. The lattice potential is generated by the ac Stark shift in an infrared standing wave near 10.6 mu m. The atoms are confined in steep potential wells with a periodicity of several micrometers. By modulating the potential depth we parametrically excite the atoms and measure their vibrational frequencie

Generative Transcriptions: An Opera of the Self
No full textThe techniques which I developed for my work between 2009-12 are a consequence of my own unique mix of synaesthetic sensibilities. I have sought to investigate these innate impulses in order to formulate a deeper understanding of my compositional process and define technical strategies that I have termed generative transcriptions.
In this thesis I focus on CANTO MORPH, ‘an opera of the self’, a project in multiple parts exploring processes of embodiment, association and dissociation. It is realised through the media of recorded improvisation, a 45-minute scored composition, a virtual architecture, a media installation, a video installation and a sculptural libretto.
This project as ‘an opera of the self’ is located in an experiential process comprising several stages:
1/ I perform a series of improvisations in a trance-like state using various instruments and my own voice to create multi-layered recordings – trance improvisation mix.
2/ These recordings are subjected to analytical transcription which I understand as a process of reverse engineering akin to the process that architects employ whereby complex 3-dimensional structures of buildings are analysed and explored diagrammatically in order to discover what kind of essence might be contained in the blueprint of its built form. I cite Xenakis’ Philips Pavilion and the dual nature of composition/architecture that is embodied within this design. This process inspires my own methodology, where mimetic scripts are created from the trance improvised mix and then refined and further manipulated into a score that can be performed.
3/ The improvisation-analysis-composition process which can broadly be conceived as an ‘embodiment of self’ is subjected to another stage in which I create a new body – a re-embodiment in which to site the work architecturally.
In exploring the multi-modal approach that is represented by the CANTO MORPH, I have underpinned a novel and multi-facetted way to approach a compositional practice, where through synaesthetic empowerment, a myriad of forces enable an emergent compositional method of generative transcriptions
Team Governance: Empowerment or Hierarchical Control
No full textWe investigate a team setting in which workers have different degrees of commitment to the outcome of their work. We show that if there are complementarities in production and if the team manager has some information about team members, interventions that the manager undertakes in order to assure certain efforts may have destructive effects: they can distort the way workers perceive their fellow workers and they may also lead to a reduction of effort by those workers that care most about output. Moreover, interventions may hinder the development of a cooperative organizational culture in which workers trust each other. Thus, our framework provides some first insights into the costs and benefits of interventions in teams. It identifies that team governance is driven by the importance of tasks that cannot be monitored. The more important these tasks, the more likely it is that teams are empowered.team work, incentives, informed principal, intrinsic motivation
Human Smuggling
No full textDespite its importance in global illegal migration, there is little, and mostly theoretical research on human smuggling. We suggest an analytical framework to understand the micro structure of the human smuggling market. Migrants interact with smuggling and financing intermediaries; these may or may not be integrated with each other, and with the migrants' employers. Policies of receiving countries (border controls, employer sanctions, deportation policies, sales of visa) affect the interactions in the smuggling market, and, hence, migration flows. We review the theoretical work, point to the scarce empirical evidence, and identify challenges for future theoretical, empirical work and policy advice.illegal migration, trafficking
Golden Rule Series #2 (The Modern McGuffey Readers)
No full textSix fables, each ending a section of this early grade-school reader. See 40, 76, 108, 144, 179, and 216. Simple colored pictures in a mass-produced book. TH on 216 presents a good graphic illustration of what dawdling means. GA is curiously softened: the ant says nothing in winter, and the grasshopper learns he was wrong to laugh at her.This is a hardbound book (hard cover)Ullin W. Leavell and Mary Louise Friebel
