The Power of Unentanglement

The class QMA(k). introduced by Kobayashi et al., consists of all languages that can be verified using k unentangled quantum proofs. Many of the simplest questions about this class have remained embarrassingly open: for example, can we give any evidence that k quantum proofs are more powerful than one? Does QMA(k) = QMA(2) for k ≥ 2? Can QMA(k) protocols be amplified to exponentially small error? In this paper, we make progress on all of the above questions. * We give a protocol by which a verifier can be convinced that a 3SAT formula of size m is satisfiable, with constant soundness, given Õ (√m) unentangled quantum witnesses with O(log m) qubits each. Our protocol relies on the existence of very short PCPs. * We show that assuming a weak version of the Additivity Conjecture from quantum information theory, any QMA(2) protocol can be amplified to exponentially small error, and QMA(k) = QMA(2) for all k ≥ 2. * We prove the nonexistence of "perfect disentanglers" for simulating multiple Merlins with one

The Management of Technology Transfer Plenary Paper

The future world economic development as well as the improvement of other aspects of the quality of life depends to a very large extent on technological development, which again depends essentially on the successful application of the process of technological innovation. This process with its various stages of research, development, engineering, and marketing cannot function without effective communication for the purpose of technology transfer, i.e., transferring knowledge between the stages.It is important not only to understand the process of technological innovation and to realize that technology transfer is an essential part of it, but also to understand that technology transfer is the transferring of knowledge rather than of goods and services, and is dependent on successful communication. Further, technology transfer should be managed as part of the package of managing technological innovation, which should be purposeful and continuous rather than a response to haphazard demands.One of the aims of the National Timber Research Institute is to promote the more efficient use of the South African wood resource as a reliable and economical structural material. Research results in this field have been successfully transferred to the South African forest products industry where 90 low cost stress-grading machines are now in use, and where stress-graded timber is selectively used in glulam products and 20% of all roof trusses.The low cost grading machine, the grading system, the design data, the roof truss design method and computer program, as well as the glulam manufacturing systems, were developed by the National Timber Research Institute and transferred to industry by way of research steering committees, symposia, publications, industry-sponsored development contracts, and direct assistance in factories

What Happens After Going Live With ERP Systems? Competence Centers Can Support Effective Institutionalization

The process of initiating, implementing and institutionalizing an enterprise resource planning (ERP) software package in an organization is non-trivial. Competence centers (CC) have been proposed as a means to support organizational performance during the ongoing operations and maintenance phase of the life cycle. CC can be designed to support only the technical aspects of ERP software maintenance (e.g., updating tables as the business changes), but they can also be a resource for end user education, training, and support. In addition, they can be a focus of ongoing improvements in business processes and can enable retention of organizational knowledge about the rationale for software configuration decisions, which is critical for future upgrades, migrations, and conversions. This paper describes the role a CC can play by examining the problems that one firm experienced after it “went live” with ERP. We conclude with some suggestions for future research

‘The longest suicide vote in history’: the Labour Party leadership election of 2015

The Labour leadership contest of 2015 resulted in the election of the veteran Left-wing backbencher, Jeremy Corbyn, who clearly defeated the early favourite, Andy Burnham. Yet Corbyn enjoyed very little support among Labour MPs, and his victory plunged the PLP into turmoil, particularly as he was widely viewed as incapable of leading the Party to victory in the 2020 general election. Given that, much of the established academic literature on Party leadership contests emphasises the ability to foster unity, and thereby render a party electable, as two of the key criteria for electing a new leader, coupled with overall competence, important questions are raised about how and why the Labour Party chose someone to lead them who clearly does not meet these criteria. We will argue that whilst these are the natural priorities of MPs when electing a new leader, in Corbyn’s case, much of the extra-parliamentary Labour Party was more concerned about ideological conviction and purity of principles, regardless of how far these diverged from public opinion. This was especially true of those who signed-up to the Labour Party following the 2015 general election defeat. Indeed, many of these only did so after Corbyn had become a candidate. This clearly suggests a serious tension between maximising intra-party democracy and ensuring the electability of the parliamentary party itself

Family Planning Targets and Quality of Services: Workers' Perspectives and Dilemmas

This paper uses data from in-depth group interviews with family planning workers in Bangladesh to demonstrate both the dysfunctional influence of family planning targets on quality of care as well as the strong connection between targets and the manage ment system. The findings show that the presence of targets influenced the advice and information workers provided, pushing them towards long-term methods such as steril isation and the IUD rather than helping clients select methods most suited to their needs. The paper then shows the connection between the target system and the struc ture of official and unofficial incentives, the pattern of supervision, the system of accountability and a hierarchically organised and gender-biased organisational cul ture. The authors argue that unless these underlying managerial determinants of qual ity of care are addressed, the hope for reaching the goals of the International Conference on Population and Development (ICPD) will remain illusory.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69103/2/10.1177_097206349900100206.pd

Understanding Digital Humanities

2012 In the first decade of the 21 st century, the researchers in the humanities and humanistic social sciences have gradually started to adopt computational and visualization tools. The majority of this work often referred as "digital humanities" has focused on textual data (e.g., literature, historical records, or social media) and spatial data (e.g., locations of people, places, or events visualization and computational analysis of large collections of images and video suitable for researchers in media studies, the humanities, and the social sciences who do not have technical background, and to apply these techniques to progressively large media data sets. Our second goal was theoretical -to examine existing practices and assumptions of visualization and computational data analysis (thus the name "Software Studies"), and articulate new research questions enabled by humanistic computational work with "big cultural data" in general, and visual media specifically. 3 This chapter draws on the number of my articles written since we started the lab where I discuss history of visualization, the techniques that we developed for visualizing large sets of visual media, and their applications to various types of media. 4 The reader is advised to consult these 1 For recent discussions of digital humanities, see David M
