    Ways to Be Worse Off

    Does disability make a person worse off? I argue that the best answer is yes and no, because we can be worse off in two conceptually distinct ways. Disabilities usually make us worse off in one way (typified by facing hassles) but not in the other (typified by facing loneliness). Acknowledging two conceptually distinct ways to be worse off has fundamental implications for philosophical theories of well-being.

    The Status of Queen Conch, Strombus gigas, Research in the Caribbean

    Today there are approximately 230 published scientific papers on queen conch, Strombus gigas. Publication on this species began in the 1960's and increased rapidly during the 1980's and 1990's (Fig. 1). The increase in publication after 1980 was associated with three particular areas ofendeavor. First, many articles were published to document the rapid depletion of conch stocks throughout the Caribbean Sea. Second, substantial progress was made in understanding processes related to growth, mortality, and reproduction in queen conch. Third, because of the apparent and widespread decline in conch, several research laboratories, especially in Florida, Puerto Rico, Venezuela, and the Turks and Caicos Islands began experiments related to hatchery production of juvenile conch. The primary intent was to replenish wild stocks by releasing hatchery-reared animals. Today, hatchery production has been relatively well perfected, and the increase in numbers of scientific papers related specifically to culture has slowed. A thorough review of the history of conch mariculture was provided by Creswell (1994), and Davis (1994) summarized the details of larval culture technique

    Prediction of discard mortality for Alaskan crabs after exposure to freezing temperatures, based on a reflex impairment index

    Millions of crabs are sorted and discarded in freezing conditions each year in Alaskan fisheries for Tanner crab (Chionoecetes bairdi) and snow crab (C. opilio). However, cold exposures vary widely over the fishing season and among different vessels, and mortalities are difficult to estimate. A shipboard experiment was conducted to determine whether simple behavioral observations can be used to evaluate crab condition after low-temperature exposures. Crabs were systematically subjected to cold in seven different exposure treatments. They were then tested for righting behavior and six different ref lex actions and held to monitor mortality. Crabs lost limbs, showed ref lex impairment, and died in direct proportion to increases in cold exposure. Righting behavior was a poor predictor of mortality, whereas reflex impairment (scored as the sum of reflex actions that were lost) was an excellent predictor. This composite index could be measured quickly and easily in hand, and logistic regression revealed that the relationship between reflex impairment and mortality correctly predicted 80.0% of the mortality and survival for C. bairdi, and 79.4% for C. opilio. These relationships provide substantial improvements over earlier approaches to mortality estimation and were independent of crab size and exposure temperature

    Paying to Play: Social Media in Advancement 2016

    To cut through the growing chatter across social media channels, many educational institutions are paying to increase the visibility of their content on Facebook, Twitter and other digital platforms, according to a new white paper by CASE, Huron and mStoner, Inc."Paying to Play: Social Media in Advancement 2016" reports that 83 percent of surveyed respondents are boosting or promoting posts or advertising on Facebook; 16 percent are advertising or promoting tweets on Twitter and 9 percent report advertising on LinkedIn.Schools, colleges and universities worldwide are paying to boost and promote content as the organic reach across all social channels declines, write "Paying to Play" co-authors Jennifer Mack of Huron and Michael Stoner of mStoner Inc."Paying to improve exposure is the single best way to ensure that a particular piece of content reaches as many fans and followers as possible, allowing them the opportunity to engage with it in some way," according to Mack and Stoner.Surveyed institutions boosted, promoted or advertised posts to increase attendance at events, encourage more engagement with an important campaign and grow awareness of giving days, among other reasons. These institutions, however, were selective about which posts to boost as most don't yet have much, if any, budget for amplifying social content.Beyond this growing pay-to-play trend among educational institutions, the white paper reveals common practices of institutions that are most successful with social media. According to the white paper, these institutions are:More likely to boost, promote and advertise their postsMore likely to share content generated by their constituents on social channelsLikely to use social media for prospect researchAdept at turning their expertise in using social media into dollars for their institutionsOther findings include:Nearly 90 percent of respondents agreed that social media is a much more important part of their communications and marketing efforts than three years ago.When convincing senior leadership of the value of social media, 45 percent of respondents point to the opportunity to connect with new audiences while 42 percent name the ability to engage young alumni.Use of Instagram rose from 54 percent in 2015 to 65 percent in 2016.Use of Snapchat grew from 5 percent in 2015 to 15 percent in 2016."Paying to Play: Social Media in Advancement 2016" reports on findings from the seventh survey of social media in advancement, which was conducted earlier this year by Huron and mStoner in partnership with CASE. Nearly 1,200 respondents at educational institutions worldwide provided feedback on their use of social media

    Social Media Enters the Mainstream: Report on the Use of Social Media in Advancement, 2014

    Social media use is becoming increasingly engrained in the work of alumni relations, communications, fundraising and marketing professionals at educational institutions, according to results cited in a new white paper. This white paper reports on findings from the fifth survey of social media in advancement, conducted earlier this year by Huron Education and mStoner in partnership with the Council for Advancement and Support of Education. Nearly 2,000 respondents provided feedback on the tools they are using, how they use them, which are most successful and how to measure return on investment. Among the notable findings is growing recognition by advancement practitioners of the importance of social media to advancement. The white paper includes three profiles of institutional executives who successfully use social media

    Itinerant Ferromagnetism in ultracold Fermi gases

    Get PDF
    Itinerant ferromagnetism in cold Fermi gases with repulsive interactions is studied applying the Jastrow-Slater approximation generalized to finite polarization and temperature. For two components at zero temperature a second order transition is found at akF≃0.90ak_F\simeq0.90 compatible with QMC. Thermodynamic functions and observables such as the compressibility and spin susceptibility and the resulting fluctuations in number and spin are calculated. For trapped gases the resulting cloud radii and kinetic energies are calculated and compared to recent experiments. Spin polarized systems are recommended for effective separation of large ferromagnetic domains. Collective modes are predicted and tri-critical points are calculated for multi-component systems.Comment: 8 pages, 6 figure
