Cost efficiency and UK building societies. An econometric panel-data study employing a flexible fourier functional form

The paper empirically quantifies firm specific 'distribution free' cost efficiency, economies of scale and economies of scope in the UK building society sector between 1990-1995. Both a flexible Fourier and a translog functional form are employed with an intermediation representation of depository institution production. Differences in the performance of these two functional forms are found. A broad distribution of cost efficiency over the sample period is observed, with a mean efficiency of 76 per cent estimated using the flexible Fourier form and a mean efficiency of 72.52 per cent estimated employing the translog form. Distinct results for economies of scale are produced with the two models

Design Process and Organisational Strategy: A Storytelling Perspective

This paper explores the relationship between design process and organisational strategy through a storytelling perspective by providing a literature review; firstly, in relation to society in general; establishing a contextual background to the research. Secondly, by relating this to a) how designers and design researchers examine storytelling within design process, and b) how organisational strategists theorise storytelling. Then finally, through comparing and contrasting the literature, unearth the relevancies of using a storytelling perspective and uncover opportunities for understanding how design process impacts organisational strategy. It is apparent that certain underlying principles in adopting a storytelling perspective when employing organisational strategy and design process coexist. Foremost are the human centred focuses; in particular building relationships and constructing identities. Concerning the approaches to storytelling, a shared desire to elicit emotional resonance with audiences exists in the use of characterisation. During collaboration between designers and organisations, stories resulting from the design process will incontrovertibly have the potential to impact that company’s peoples. Examining collaborations between designers and organisations from the perspective of storytelling could lead to a deeper understanding of the impact design can have in an organisation, particularly along the themes of a sense of community, constructing meaning and affecting change within organisations

Rethinking Disability in the Private Sector: Report from the Panel on Labour Market Opportunities for Persons with Disabilities

In July 2012, the Government of Canada appointed a panel to consult with private sector employers, as well as other organizations and individuals, on the labour market participation of people with disabilities. The panel members were asked to identify successes and best practices in the employment of people with disabilities, as well as the barriers faced by employers, and to report on their findings. In-person and telephone consultations were conducted with almost 70 employers, and feedback was received from approximately 130 online submissions. Responses came from organizations of all sizes across the country and in a broad range of industry sectors. Findings were shared anonymously with a number of national non-profit organizations and business associations to determine if they resonated with other stakeholders. While the consultations were the main focus of the panel’s efforts, research was also conducted into the business case associated with hiring people with disabilities in Canada and other jurisdictions. This report is directed at Canadian private sector employers, and offers the following findings: Many companies are doing great things, but more education and training are needed (see “Employers speak”). While most of the companies we heard from showed a genuine desire to hire people with disabilities, education and training are required to overcome barriers, dispel myths and put theory into practice. As the examples of forward-thinking Canadian companies and their best practices testify, there is significant experience available on which to build. Hiring people with disabilities is good for business. (see “Understanding the business case”). We heard this from senior and experienced business leaders who recognize the value of an inclusive work environment. Although mainly intuitive, their beliefs are supported by the performance of corporate diversity leaders on the capital markets, as well as data on employee retention and productivity. It is noteworthy that in 57 percent of cases, no workplace accommodation is required for people with disabilities. In the 37 percent of cases reporting a one-time cost to accommodate an employee with a disability, the average amount spent is $500. The keys to success are leadership and effective community partnerships (see “Making it work for you”). To increase employment among people with disabilities and access the related benefits, tone from the top and the actions of leaders are imperative. Also critical is identifying community partners who fully understand the business’s talent needs and are committed to customer service. To help organizations begin the process of engaging and employing talented people with disabilities, this section also includes a list of initiatives called “Getting started.

MetaSpace II: Object and full-body tracking for interaction and navigation in social VR

MetaSpace II (MS2) is a social Virtual Reality (VR) system where multiple users can not only see and hear but also interact with each other, grasp and manipulate objects, walk around in space, and get tactile feedback. MS2 allows walking in physical space by tracking each user's skeleton in real-time and allows users to feel by employing passive haptics i.e., when users touch or manipulate an object in the virtual world, they simultaneously also touch or manipulate a corresponding object in the physical world. To enable these elements in VR, MS2 creates a correspondence in spatial layout and object placement by building the virtual world on top of a 3D scan of the real world. Through the association between the real and virtual world, users are able to walk freely while wearing a head-mounted device, avoid obstacles like walls and furniture, and interact with people and objects. Most current virtual reality (VR) environments are designed for a single user experience where interactions with virtual objects are mediated by hand-held input devices or hand gestures. Additionally, users are only shown a representation of their hands in VR floating in front of the camera as seen from a first person perspective. We believe, representing each user as a full-body avatar that is controlled by natural movements of the person in the real world (see Figure 1d), can greatly enhance believability and a user's sense immersion in VR.Comment: 10 pages, 9 figures.

Solving constraints within a graph based dependency model by digitising a new process of incrementally casting concrete structures

The mechanisation of incrementally casting concrete structures can reduce the economic and environmental cost of the formwork which produces them. Low-tech versions of these forms have been designed to produce structures with cross-sectional continuity, but the design and implementation of complex adaptable formworks remains untenable for smaller projects. Addressing these feasibility issues by digitally modelling these systems is problematic because constraint solvers are the obvious method of modelling the adaptable formwork, but cannot acknowledge the hierarchical relationships created by assembling multiple instances of the system. This thesis hypothesises that these opposing relationships may not be completely disparate and that simple dependency relationships can be used to solve constraints if the real procedure of constructing the system is replicated digitally. The behaviour of the digital model was correlated with the behaviour of physical prototypes of the system which were refined based on digital explorations of its possibilities. The generated output is assessed physically on the basis of its efficiency and ease of assembly and digitally on the basis that permutations can be simply described and potentially built in reality. One of the columns generated by the thesis will be cast by the redesigned system in Lyon at the first F2F (file to factory) continuum workshop

Fast tunable lasers in radio-over-fiber access networks

The authors present a novel concept of employing optical wavelength packet switching (WPS) in radio-over-fiber (RoF) access networks. The Central Station is equipped with a fast tunable laser (TL), which is externally modulated with a data signal upconverted to a radio frequency. The information transmitted over the network is encoded onto different wavelengths depending on the destination base station (determined by an optical band-pass filter at that BS). Routing of traffic could be performed on a packet-by-packet basis. In such a system dynamic bandwidth allocation could be realised by varying the time the TL transmits on a particular wavelength, depending on the amount of data that needs to be sent from/to the BS. The feasibility of employing TLs in the realisation of such a system is verified by building a basic WPS RoF system. The measurements of the cross-channel interference due to the TL wavelength instability and drift are also presented. No power penalty was observed due to switching of the laser, suggesting that RoF systems based on TLs are a feasible solution to the last mile proble
