Tobacco use is projected to kill 1 billion people in the 21st century. Tobacco Use Disorder (TUD) is one of the most common substance use disorders in the world. Evidence-based treatment of TUD is effective, but treatment accessibility remains very low. A dearth of specially trained clinicians is a significant barrier to treatment accessibility, even within systems of care that implement brief intervention models. The treatment of TUD is becoming more complex and tailoring treatment to address new and traditional tobacco products is needed. The Council for Tobacco Treatment Training Programs (Council) is the accrediting body for Tobacco Treatment Specialist (TTS) training programs. Between 2016 and 2019, n = 7761 trainees completed Council-accredited TTS training programs. Trainees were primarily from North America (92.6%) and the Eastern Mediterranean (6.1%) and were trained via in-person group workshops in medical and academic settings. From 2016 to 2019, the number of Council-accredited training programs increased from 14 to 22 and annual number of trainees increased by 28.5%. Trainees have diverse professional backgrounds and work in diverse settings but were primarily White (69.1%) and female (78.7%) located in North America. Nearly two-thirds intended to implement tobacco treatment services in their setting; two-thirds had been providing tobacco treatment for 1 year or less; and 20% were sent to training by their employers. These findings suggest that the training programs are contributing to the development of a new workforce of TTSs as well as the development of new programmatic tobacco treatment services in diverse settings. Developing strategies to support attendance from demographically and geographically diverse professionals might increase the proportion of trainees from marginalized groups and regions of the world with significant tobacco-related inequities.

A Study of the air routes of the world brings out almost at once the fact that some of the most difficult route are also the most attractive. For instance, the North Atlantic route which couples North America with Europe is certainly one of the most difficult in the world, but also by the fact that it couples two of the most densely populated, as well as the most wealthy groups of people in the world, one of the most attractive.

AbstractMany glaciers in Svalbard and in other glacierized areas of the world are known to surge. However, the time series of observations required to assess the duration of fast motion is very restricted. Data on active-phase duration in Svalbard come from aerial photographs, satellite imagery, field surveys and airborne reconnaissance. Evidence on surge duration is available for eight Svalbard ice masses varying from 3 to 1250 km2. Worldwide, active-phase duration is recorded for less than 50 glaciers. Few observations are available on high polar ice masses. The duration of the active phase is significantly longer for Svalbard glaciers than for surge-type glaciers in other areas from which data are available. In Svalbard, the active phase may last from 3 to 10 years. By contrast, a surge duration of 1–2 years is more typical of ice masses in northwest North America, Iceland and the Pamirs. Ice velocities during the protracted active phase on Svalbard glaciers are considerably lower than those for many surge-type glaciers in these other regions. Mass is transferred down-glacier more slowly but over a considerably longer period. Svalbard surge-type glaciers do not exhibit the very abrupt termination of the active phase, over periods of a few days, observed for several Alaskan glaciers. The duration of the active phase in Svalbard is not dependent on parameters related to glacier size. The quiescent phase is also relatively long (50–500 years) for Svalbard ice masses. Detailed field monitoring of changing basal conditions through the surge cycle is required from surge-type glaciers in Svalbard in order to explain the significantly longer length of the active phase for glaciers in the archipelago, which may also typify other high polar ice masses. The finding that surge behaviour, in the form of active-phase duration, shows systematic differences between different regions and their environments has important implications for understanding the processes responsible for glacier surges.

AbstractThe phenomenon of mass surveillance has confronted legal systems throughout the world with significant challenges to their fundamental norms and values. These dilemmas have been most extensively studied and discussed in relation to the kind of privacy cultures that exist in Europe and North America. Although mass surveillance creates the same kinds of challenges in Muslim countries, the phenomenon has rarely been discussed from the perspective of Shari’a. This article seeks to demonstrate that this neglect of mass surveillance and other similar phenomena by Shari’a scholars is unjustified. Firstly, the article will address objections that Shari’a does not contain legal norms that are relevant to the modern practice of state surveillance and that, if these exist, they are not binding on rulers and will also seek to show that, whatever terminology is employed, significant aspects of the protection of privacy and personal data that exists in other legal systems is also be found deeply-rooted in Shari’a. Secondly, it will assess the specific requirements that it makes in relation to such intrusion on private spaces and private conduct and how far it can benefit from an exception to the general prohibition on spying. Finally, it is concluded that mass surveillance is unlikely to meet these Shari’a requirements and that only targeted surveillance can generally do so.

HIV infections are prevalent among adolescents and young adults, of whom 44% remain unaware of their diagnosis. HIV screening presents numerous challenges including stigma, fear, and concerns about confidentiality, which may influence young people’s acceptance of HIV screening and linkage to care differently from individuals in other age groups. It is imperative to understand which care delivery models are most effective in facilitating these services for youth. This systematic review analyzes the rates of HIV test acceptance and linkage to care by care delivery model for adolescents and young adults. Studies were classified into emergency department (ED), primary care/inpatient setting, community-based program, or sexually transmitted infection clinic models of care. From 6395 studies initially identified, 59 met criteria for inclusion in the final analyses. Rate of test acceptance and linkage to care were stratified by model of care delivery, gender, race, age ranges (13–17, 18–24 years) as well as site (North America vs rest of the world). A significant difference in acceptance of HIV testing was found between care models, with high rates of test acceptance in the ED setting in North America and primary care/hospital setting in the rest of the world. Similarly, linkage to care differed by model of care, with EDs having high rates of linkages to HIV care in North America. Future studies are needed to test mechanisms for optimizing outcomes for each care delivery model in addressing the unique challenges faced by adolescents and young adults.

Edward FitzGerald (b. 1809–d. 1883) was an English poet and translator, best remembered today for a single work, his Rubáiyát of Omar Khayyám (1859). FitzGerald was born into an extremely wealthy family in Suffolk. After graduating from Cambridge, where he had spent perhaps the happiest years of his life and formed a number of lifelong friendships, FitzGerald returned to Suffolk. There he lived very modestly, either in a cottage on the outskirts of his family’s estate or in rented lodgings in a nearby town, occupying himself with reading and writing. In the early 1850s he began to translate from Spanish, publishing Six Dramas of Calderon in 1853. The very free and unliteral method of translation he used in this work would mark all of his later translations as well, which included works by Aeschylus, Sophocles, and the Persian poet Jámí. But it was his translation, or adaptation, of certain rubáiyát (quatrains) attributed to the 12th-century Persian polymath Omar Khayyám that caused a worldwide sensation. The first edition of Rubáiyát of Omar Khayyám, which FitzGerald published anonymously (like his other works), in 1859, consisted of seventy-five quatrains. At first no one noticed or purchased the small, pamphlet-like book, but a few years later it was discovered by chance by members of the Pre-Raphaelite circle, who became passionately devoted to it. A second edition of 110 quatrains was published in 1868 and began to draw attention in North America as well as in Britain. Two more editions followed, each varying fairly significantly from the others, before FitzGerald’s death in 1883, by which time the poem was known throughout the world. It was translated into numerous languages, and Omar Khayyám clubs were founded in many cities. Critics have attributed this popularity to the poem’s frank embrace of a skeptical, resigned, epicurean view of life, which caught the spirit of a doubting, world-weary age. Its very success—by 1900 the Rubáiyát was the most popular and most frequently reprinted poem in English—led to its being dismissed and ignored by literary critics for much of the 20th century. But a critical revival began in the late 1990s, as scholars started to reappraise the poem’s cultural significance as well as its literary achievement.
