An improved magnetic tape recorder

Magnetic tape recorder employs a single capstan for simultaneously driving the supply and take-up reels in such a manner that the tape passing between the reels is kept under a predetermined constant tension. This recorder operates with little power and is sufficiently rugged to withstand the severe stresses encountered in high-altitude balloon flight tests

The regulation of a project of the deregulation: UBER in Brazil and the European Union

Purpose – This paper focuses on the regulation of Uber at regional level (Sao Paulo and Brasilia), national level (European Member States) and supranational level (The European Commission initiative), which are often too restrictive. Methodology/approach/design – This article analyses standards and literature on regulation, as well as the role of competition. Attention was specially drawn to the market failure theory for justifying regulation, advocated by Breyer, Ogus and Baldwin & Cave. Due to the fact that there will be an evaluation of the regulations in place, consequentialism, welfarism and Pareto are briefly mentioned. Findings – None of the current regulatory responses, at the exception to Sao Paulo and the initiative by the European Commission that are not based exclusively on market failure theory, are working. Indeed, Uber is still banned in various cities. In others, the regulatory burden is so high that it takes away any incentives that Uber created. Regulation is not the only exit to market failure, competition must play a role. Uber is based on deregulation of the market and to try to regulate such concept with conventional theories will only lead to failures and restrictions. Practical implications – This article discusses the possible improvements to the already existing regulations. Originality/value – This paper correlates the regulation of Uber in Brazil and in Europe, explaining the difficulties these regulations are creating for Uber

Software system safety

Software itself is not hazardous, but since software and hardware share common interfaces there is an opportunity for software to create hazards. Further, these software systems are complex, and proven methods for the design, analysis, and measurement of software safety are not yet available. Some past software failures, future NASA software trends, software engineering methods, and tools and techniques for various software safety analyses are reviewed. Recommendations to NASA are made based on this review

A Commentary on Litigation Involving Uber Technologies, Inc.

Uber Technologies, Inc. is a peer-to-peer ridesharing, food delivery, and transportation network managed in San Francisco, California. Travis Kalanick and Garrett Camp developed the idea for the ridesharing app in 2008, after experiencing difficulty hailing a cab. They originally designed the app to be used in major metropolitan areas, but the business inevitably took off; it now operates in 633 cities worldwide. In 2017, Uber claimed that the company earned roughly $7.5 billion in revenue, employed more than 12,000 “independent drivers,” and connected over one billion people (“Finding the Way”). Though widely successful and heralded as a major influencer in the “gig economies,”1 or “sharing economies,”2 its role in the vanguard has attracted much criticism and engendered a plethora of lawsuits. According to the Courthouse News database, Uber has been sued at least 433 times in 2017 alone (Kahn, Robert)

On the acylindrical hyperbolicity of the tame automorphism group of SL2(C)\mathrm{SL}_2(\mathbb{C})

We introduce the notion of \"uber-contracting element, a strengthening of the notion of strongly contracting element which yields a particularly tractable criterion to show the acylindrical hyperbolicity, and thus a strong form of non-simplicity, of groups acting on non locally compact spaces of arbitrary dimension. We also give a simple local criterion to construct \"uber-contracting elements for groups acting on complexes with unbounded links of vertices. As an application, we show the acylindrical hyperbolicity of the tame automorphism group of $\mathrm{SL}_2(\mathbb{C})$, a subgroup of the $3$-dimensional Cremona group, through its action on a CAT(0) square complex recently introduced by Bisi-Furter-Lamy.Comment: 16 pages, 1 figur

The need for a new legal framework for VTC licenses to allow competition in the services of city transport -including taxis-. A matter of EC Competition Policy

In the recent years, the phenomenon of the sharing economy has played an important part in the market of the city transport of passengers. The performance of these digital platforms such as Uber, Blablacar or Cabify has been full of controversy. So far, the debate has been focused on the qualification of the service provided by these platforms. Once that –according to the Conclusions of AG Spuznar, to the case Elite Taxi vs. Uber of the ECJ- it seems pretty clear that these companies do provide a service of transportation, it is important to consider the legal framework of this activities.Universidad de Málaga.

A Modern Union for the Modern Economy

Membership in traditional unions has steeply declined over the past two decades. As the White House and Congress are now completely Republican controlled, there promises to be no reversal of this trend in the near future. In the face of this rejection of traditional bargaining efforts, several attempts have been made to create alternative “quasi-union” or “alt-labor” relationships between workers and employers. These arrangements represent a creative approach by workers to have their voices heard in a collective manner, though still falling far short of the traditional protections afforded by employment and labor law statutes. This Article critiques one such high-profile, quasi-union effort in the technology sector—the Uber Guild. While the Guild does not provide any of the traditional bargaining protections found in the National Labor Relations Act (NLRA), it offers Uber drivers some input over the terms and conditions under which they work. Falling somewhere between employment-at-will and unionization protected under the NLRA, the Uber Guild is a creative attempt to help both workers and the company to better understand how they can improve the working relationship. This Article navigates the Uber Guild and other nontraditional efforts that promise a collective voice for workers in the face of a precipitous decline in union membership. This Article further explores how workers in the technology sector face unique challenges under workplace laws. We argue that these workers are particularly well situated to benefit from a nontraditional union model and explain what that model should look like. While a traditional union protected by the NLRA is the optimal bargaining arrangement, we must consider the enormous challenges workers in the technology sector face in obtaining these protections

Uber and airbnb: the legal and policy debate in NSW

Outlines the legal status of Airbnb and Uber operations in NSW, and contains an overview of each platform and current usage in Sydney, and where applicable, more broadly in NSW. Introduction The way in which people consume goods and services has changed dramatically since the birth of web and app-based sharing platforms. By connecting demand and share capacity in real-time, they act like “virtual matchmakers” by lowering transaction costs and facilitating arrangements that might otherwise have been too burdensome. Airbnb and Uber are two platforms that have made their way to NSW in recent years, gathering considerable momentum with consumers. Their expansion has not come without detractors, most notably the long-established taxi and hotel industries.   Their regulation has consequently become an emerging policy concern, coming to the fore at the State level when Opposition Leader Luke Foley advocated the need for regulation of ride- sharing platforms such as Uber
