Growth rate for the expected value of a generalized random Fibonacci sequence

A random Fibonacci sequence is defined by the relation g_n = | g_{n-1} +/- g_{n-2} |, where the +/- sign is chosen by tossing a balanced coin for each n. We generalize these sequences to the case when the coin is unbalanced (denoting by p the probability of a +), and the recurrence relation is of the form g_n = |\lambda g_{n-1} +/- g_{n-2} |. When \lambda >=2 and 0 < p <= 1, we prove that the expected value of g_n grows exponentially fast. When \lambda = \lambda_k = 2 cos(\pi/k) for some fixed integer k>2, we show that the expected value of g_n grows exponentially fast for p>(2-\lambda_k)/4 and give an algebraic expression for the growth rate. The involved methods extend (and correct) those introduced in a previous paper by the second author

Developing an Identity of Responsible Lawyering through Experiential Learning

Professor La Rue explores the use of student lawyering experiences in the development of a responsible professional identity. He shows how it is possible, through the selection of practice settings that situate students side-by-side with subordinated people, for students to understand law as a multidimensional enterprise. His goal is to help us understand law as a translation of human stories and to recognize how this translation involves value laden choices that have the effect of silencing certain voices

Governing Asylum without ''Being There": Ghost Bureaucracy, Outsourcing, and the Unreachability of the State

When, where, and how do asylum seekers encounter the state? Anyone seeking asylum in the Global North might meet state authorities of the country where they want to apply for international protection long before arriving at its borders. However, if the state often becomes “very present” by transcending its geopolitical margins in border control, once asylum seekers have managed to cross into national territory, the state frequently vanishes. Insufficient information, opaque proceedings, and difficulties in reaching state agencies, which dramatically increased with the COVID pandemic, often translate into a denial of asylum seekers’ rights and their exclusion from welfare programs. Moreover, following a widespread tendency to outsource public services, access to asylum and related welfare programmes are being increasingly mediated by a range of nonstate actors (such as NGOs, activist groups, companies, and individuals) acting as state agents. Drawing on the analysis of ethnographic results from Spain and Italy, this article proposes the concept of “ghost bureaucracy” to theorise the street-level bureaucrats from their absence and explore asylum seekers’ encounters with a seemingly powerful and omnipresent but unreachable state through closed offices, digital bureaucracy and third-party actors

Transmission of PhC coupled-resonator waveguide (PhCCRW) structure enhanced via mode matching

A method for increasing the coupling efficiency between ridge optical waveguides and PhCCRWs is described. This increase is achieved via W1 channel waveguide sections, formed within a two-dimensional triangular lattice photonic crystal using mode-matching. The mode-matching is achieved by low quality-factor modified cavities added to both the input and output ports of the PhCCRW. A three dimensional finite-difference time-domain method has been used to simulate light propagation through the modified PhCCRW. We have fabricated PhCCRWs working at 1.5µm in silicon-on-insulator material. Measurements and simulations show that the overall transmission is improved by a factor of two

Increasing optical metamaterials functionality

Gold Split Ring Resonators (SRRs) were fabricated on silicon substrates by electron beam lithography and lift-off, with overall dimensions of approximately 200 nm. Reflectance spectra from the SRRs are similar to those published elsewhere. New devices are proposed based on the additional functionality afforded by the use of a silicon substrate

Private & public good research and extension (R&E) roles in precision farming

Background: Precision dairy technologies are principally developed by private companies. Research has shown these companies can lack farm systems expertise to support on-farm use and adaptation, leading to uncertainty about how to best use technologies on-farm. Support structures are required to facilitate learning and reduce uncertainty for farmers, however this currently represents an area of market failure. Methods: A timeline analysis methodology was used to explore roles of public and private organisations in the development of precision dairy farming in New Zealand. This timeline method facilitates documentation and understanding of the important stages of an innovation processes. We used a meta-analysis and expert knowledge to identify and describe these important stages. These were then analysed using the seven-stage Hekkert framework for innovation systems functions. Results: There were several key events in the development of PD in New Zealand. These included the Greenfields Robotic Milking project, instigation of the livestock traceability scheme (NAIT), evolution of dairy technology start-ups, and the influence of multi-national dairy technology companies. Discussion: PD technologies are complex in nature and require a collaborative approach for successful innovation and adoption. Commercial organisations vary in their ability to support the technologies on farm. Historically, physical technologies (such as sensors) were the main focus, however in recent years there has been significant activity in development on online platforms for collating and analysing data for farm management decision support. Successful uptake of these products by farmers will require enhanced data integration and transfer to minimise ‘computer time’ for farmers and maximise useability. Conclusion: The PD innovation system in New Zealand remains relatively immature and requires greater industry-level leadership to improve performance across the various innovation system functions. In the rapidly evolving agri-tech sector, a focus is required on more open innovation structures and building farmer skills and knowledge about technology options
