Nameless in Cyberspace: Anonymity on the Internet

Proposals to limit anonymous communications on the Internet would violate free speech rights long recognized by the Supreme Court. Anonymous and pseudonymous speech played a vital role in the founding of this country. Thomas Paine's Common Sense was first released signed, "An Englishman." Alexander Hamilton, John Jay, James Madison, Samuel Adams, and others carried out the debate between Federalists and Anti-Federalists using pseudonyms. Today, human rights workers in China and many other countries have reforged the link between anonymity and free speech. Given the importance of anonymity as a component of free speech, the cost of banning anonymous Internet speech would be enormous. It makes no sense to treat Internet speech differently from printed leaflets or books

The Specter of Pervasiveness: Pacifica, New Media, and Freedom of Speech

Under the legal doctrine of pervasiveness, media such as television and radio get much less protection from censorship than do print media. The Supreme Court should reject the pervasiveness doctrine as a dangerously broad and vague excuse for speech regulation. If the doctrine applies to any medium, it could arguably apply to all media. The pervasiveness doctrine thus threatens to curtail the First Amendment's protection of freedom of speech. The pervasiveness doctrine relies on a crabbed view of individual responsibility and property rights. We invite the broadcast media into our homes and alone bear the responsibility for controlling our children's access. The pervasiveness doctrine wrongly puts such choices in the hands of politicians and bureaucrats. Technological advances threaten to lead to wider applications of the pervasiveness doctrine. As the Internet expands into one-to-many voice or video communications, courts might decide to treat it as the legal equivalent of pervasive radio or TV broadcasts

Compelling Project Management

Successfully delivering a project, task, or even a group decision requires effective collaboration skills, and the great thing about skills is that they can be learned. With collaboration, you can effectively lead a team toward decision making and deliver results. In this session, we will analyze different methods of collaboration to help you build this skill and make you a more persuasive and compelling project manager

Comparison of Post-injection Site Pain Between Technetium Sulfur Colloid and Technetium Tilmanocept in Breast Cancer Patients Undergoing Sentinel Lymph Node Biopsy.

BackgroundNo prior studies have examined injection pain associated with Technetium-99m Tilmanocept (TcTM).MethodsThis was a randomized, double-blinded study comparing postinjection site pain between filtered Technetium Sulfur Colloid (fTcSC) and TcTM in breast cancer lymphoscintigraphy. Pain was evaluated with a visual analogue scale (VAS) (0-100 mm) and the short-form McGill Pain Questionnaire (SF-MPQ). The primary endpoint was mean difference in VAS scores at 1-min postinjection between fTcSC and TcTM. Secondary endpoints included a comparison of SF-MPQ scores between the groups at 5 min postinjection and construction of a linear mixed effects model to evaluate the changes in pain during the 5-min postinjection period.ResultsFifty-two patients underwent injection (27-fTcSC, 25-TcTM). At 1-min postinjection, patients who received fTcSC experienced a mean change in pain of 16.8 mm (standard deviation (SD) 19.5) compared with 0.2 mm (SD 7.3) in TcTM (p = 0.0002). At 5 min postinjection, the mean total score on the SF-MPQ was 2.8 (SD 3.0) for fTcSC versus 2.1 (SD 2.5) for TcTM (p = 0.36). In the mixed effects model, injection agent (p < 0.001), time (p < 0.001) and their interaction (p < 0.001) were associated with change in pain during the 5-min postinjection period. The model found fTcSC resulted in significantly more pain of 15.2 mm (p < 0.001), 11.3 mm (p = 0.001), and 7.5 mm (p = 0.013) at 1, 2, and 3 min postinjection, respectively.ConclusionsInjection with fTcSC causes significantly more pain during the first 3 min postinjection compared with TcTM in women undergoing lymphoscintigraphy for breast cancer

Professional golf coaches’ perceptions of the key technical parameters in the golf swing

AbstractAssessing a coach's technical knowledge of a sporting technique can reveal measureable biomechanical parameters associated with successful performance. This assessment can provide new insights into technique, enhance a coach's technical knowledge or assist in optimising performance. Despite numerous golf instructional books, no scientific study has assessed a golf coach's technical knowledge of the golf swing. Therefore, the purpose of this study was to identify the key technical parameters that professional golf coaches associate with a top level golf swing; with the intention of using the results to guide future golf biomechanics research and coaching technologies. Initially, sixteen professional golf coaches were individually observed coaching a highly skilled golfer after which they participated in a semi-structured interview regarding their technical analysis of the golf swing. QSR-NVivo analysis software was used to inductively analyse the data using the grounded theory approach. Line-by-line coding was followed by comparison of ‘meaning units’ to form a coding hierarchy with several key technical parameters identified. A successful golf swing was defined through three elements, with “body motion” affecting “club motion” and resulting “ball flight”. Several terms described these parameters including “consistent”, “powerful”, “accurate”, “simple” and “controlled” with the most prevalent being “repeatable”. “Body motion” was influenced by five intrinsically linked key technical parameters: “posture”, “body rotation”, “sequential movement”, “hand and arm action” and “club parameters” which were further sub categorised. To conclude, the key technical parameters have been identified which will be used to support future biomechanical research in this area and to be used to direct new technologies to aid golf coaching
