E-Voting in an ubicomp world: trust, privacy, and social implications

The advances made in technology have unchained the user from the desktop into interactions where access is anywhere, anytime. In addition, the introduction of ubiquitous computing (ubicomp) will see further changes in how we interact with technology and also socially. Ubicomp evokes a near future in which humans will be surrounded by “always-on,” unobtrusive, interconnected intelligent objects where information is exchanged seamlessly. This seamless exchange of information has vast social implications, in particular the protection and management of personal information. This research project investigates the concepts of trust and privacy issues specifically related to the exchange of e-voting information when using a ubicomp type system

System of accounts for retail merchants

The Federal Trade Commission has found that the majority of retail merchants do not know accurately the cost of conducting their business and for this reason they are unable to price their goods intelligently. There must he decided improvement in this direction before competition can be placed upon a sound basis and before we can expect a decrease in the heavy business death rate among retail merchants. With the object of aiding retail merchants to improve their accounting methods we have outlined a simple system of accounts which provides for supplying the information necessary to properly direct a retail business. I commend the pamphlet to your attention and feel satisfied that if you will read it carefully you will find many helpful suggestions

Fundamentals of a cost system for manufacturers

The Federal Trade Commission has found that an amazing number of manufacturers, particularly the smaller ones, have no adequate system for determining their costs and price their goods arbitrarily. It is evident that there must be improvement in this direction before competition can be placed upon a sound economic basis. With the object of aiding in the improvement of business generally we have endeavored in this pamphlet to show briefly the importance of accurate manufacturing costs and the fundamental principles underlying them. I commend it to your attention and feel satisfied that if you will read it carefully you will find many helpful suggestions

Three-Dimensional FDTD Simulation of Biomaterial Exposure to Electromagnetic Nanopulses

Ultra-wideband (UWB) electromagnetic pulses of nanosecond duration, or nanopulses, have been recently approved by the Federal Communications Commission for a number of various applications. They are also being explored for applications in biotechnology and medicine. The simulation of the propagation of a nanopulse through biological matter, previously performed using a two-dimensional finite difference-time domain method (FDTD), has been extended here into a full three-dimensional computation. To account for the UWB frequency range, a geometrical resolution of the exposed sample was $0.25 mm$, and the dielectric properties of biological matter were accurately described in terms of the Debye model. The results obtained from three-dimensional computation support the previously obtained results: the electromagnetic field inside a biological tissue depends on the incident pulse rise time and width, with increased importance of the rise time as the conductivity increases; no thermal effects are possible for the low pulse repetition rates, supported by recent experiments. New results show that the dielectric sample exposed to nanopulses behaves as a dielectric resonator. For a sample in a cuvette, we obtained the dominant resonant frequency and the $Q$-factor of the resonator.Comment: 15 pages, 8 figure

Achieving the Potential: The Future of Federal e-Rulemaking: A Report to Congress and the President

Federal regulations are among the most important and widely used tools for implementing the laws of the land – affecting the food we eat, the air we breathe, the safety of consumer products, the quality of the workplace, the soundness of our financial institutions, the smooth operation of our businesses, and much more. Despite the central role of rulemaking in executing public policy, both regulated entities (especially small businesses) and the general public find it extremely difficult to follow the regulatory process; actively participating in it is even harder. E-rulemaking is the use of technology (particularly, computers and the World Wide Web) to: (i) help develop proposed rules; (ii) make rulemaking materials broadly available online, along with tools for searching, analyzing, explaining and managing the information they contain; and (iii) enable more effective and diverse public participation. E-rulemaking has transformative potential to increase the comprehensibility, transparency and accountability of the regulatory process. Specifically, e-rulemaking – effectively implemented – can open the rulemaking process to a broader range of participants, offer easier access to rulemaking and implementation materials, facilitate dialogue among interested parties about policy and enforcement, enhance regulatory coordination, and help produce better decisions that lead to more effective, accepted and enforceable rules. If realized, this vision would greatly strengthen civic participation and our democratic form of government

Contested resources: unions, employers, and the adoption of new work practices in US and UK telecommunications

The pattern of adoption of high-performance work practices has been explained in terms of strategic contingency and in terms of union presence. We compare the post-deregulation/privatization changes in work practice at AT&T, Bell Atlantic and British Telecom. On the basis of these cases, we argue that the choice of new work practices should be understood as a consequence not only of the company's resources or changes in its environment, nor of a simple union presence, but also as a consequence of the practices' effects on union power, the nature of the union's engagement, and the union's strategic choices

A Mixed-Methods Approach to Understanding Funder Trust and Due Diligence Processes in Online Crowdfunding Investment

We report on two studies undertaken to establish the factors that affect funders’ trust and likelihood to invest in crowdfunding campaigns online. Findings from an initial small-scale qualitative study are reported and subsequently triangulated in a larger quantitative survey. Across these studies, we demonstrate the importance of social information within the peer economy, with a strong reliance on other users across the course of the investment decision-making process. Decision making on whether to invest is informed not only by the content of the crowdfunding campaign page but also by social influence factors that are present (e.g., liking of the campaigner, reciprocity). It is further shaped by due diligence checks focused on the progression of the prototype for which funding is sought, and by assurances from outside the campaign page—namely on social media. Such assurances center around the importance of social proof, garnered through opinions of previous customers or other funders. The risk here is that much of this information is content that can be faked, and as such a reliance on this may leave potential funders vulnerable. Meanwhile, a genuine lack of prior experience and customer base means that some legitimate campaigners struggle to gain trust from potential investors who are reliant on such social information. Our findings present an empirical grounding to develop future security solutions that (1) protect existing funders and (2) increase potential funders’ level of trust, to encourage their engagement with legitimate crowdfunding campaigns

How much do we really lose?—Yield losses in the proximity of natural landscape elements in agricultural landscapes

Natural landscape elements (NLEs) in agricultural landscapes contribute to biodiversity and ecosystem services, but are also regarded as an obstacle for large‐scale agricultural production. However, the effects of NLEs on crop yield have rarely been measured. Here, we investigated how different bordering structures, such as agricultural roads, field‐to‐field borders, forests, hedgerows, and kettle holes, influence agricultural yields. We hypothesized that (a) yield values at field borders differ from mid‐field yields and that (b) the extent of this change in yields depends on the bordering structure. We measured winter wheat yields along transects with log‐scaled distances from the border into the agricultural field within two intensively managed agricultural landscapes in Germany (2014 near Göttingen, and 2015–2017 in the Uckermark). We observed a yield loss adjacent to every investigated bordering structure of 11%–38% in comparison with mid‐field yields. However, depending on the bordering structure, this yield loss disappeared at different distances. While the proximity of kettle holes did not affect yields more than neighboring agricultural fields, woody landscape elements had strong effects on winter wheat yields. Notably, 95% of mid‐field yields could already be reached at a distance of 11.3 m from a kettle hole and at a distance of 17.8 m from hedgerows as well as forest borders. Our findings suggest that yield losses are especially relevant directly adjacent to woody landscape elements, but not adjacent to in‐field water bodies. This highlights the potential to simultaneously counteract yield losses close to the field border and enhance biodiversity by combining different NLEs in agricultural landscapes such as creating strips of extensive grassland vegetation between woody landscape elements and agricultural fields. In conclusion, our results can be used to quantify ecocompensations to find optimal solutions for the delivery of productive and regulative ecosystem services in heterogeneous agricultural landscapes
