The Airy Transit Circle of the Royal Observatory, Greenwich is one of the most important instruments in the history of astronomy, navigation and time distribution. However, there has been very little research done on the history of the instrument. This article examines how the purchase of the object glass for the Airy Transit Circle involved active negotiations between George Biddell Airy and three different opticians: Georg Merz, Noel Paymal Lerebours, and William Simms. The article also shows the involvement of John Herschel and Richard Sheepshanks in Airy’s decision making process. By highlighting the presence of these individuals, the article shows how Airy’s trust and distrust in different instrument makers influenced his choice of supplier for the object glass of the Airy Transit Circle.

This article examines the role and place of British think tanks in the design and development of the country’s foreign policy towards the Central Asian region. This issue is studied in combination with an analysis of the history of the formation of British think tanks, the positions of these centers in relation to Central Asia in the early 90s of the twentieth century after the collapse of the USSR and the state of modern think tanks that study Central Asia and their influence on the decision-making process in Great Britain.

We present a clinical reasoning case of 42-year-old male with a history of type 1 diabetes who presented to hospital with decreased level of consciousness. We review the approach to coma including initial approach to differential diagnosis and investigations. After refining the diagnostic options based on initial investigations, we review the clinical decision-making process with a focus on narrowing the differential diagnosis, further investigations, and treatment.

AbstractThe South African Astronomical Observatory (SAAO), formerly known as the Royal Observatory, Cape of Good Hope, will be 200 years old in 2020. Also, South Africa (SA), formerly a British colony known as the Cape of Good Hope, will celebrate her 100-year anniversary as an International Astronomical Union (IAU) member in 2020, following the IAU centenary in 2019 that this IAU Symposium 349 celebrates. In light of all this, particularly in anticipation of the 200-year anniversary of SAAO in 2020, the SA National Research Foundation (NRF) has developed a Roadmap for the History of Astronomy in South Africa. As part of this we are conducting an oral history of astronomers to complement the historical celebrations of the institutions and science relating to astronomy in SA, supported by the SA NRF. Primarily drawing on literature and setting the scene for this work, here we present a snippet of the on-going oral histories, to glean the role of the IAU in astronomy in South Africa and show the potential of the oral histories to inform and complement written history.

ABSTRACT OBJECTIVE To review the concepts involved in the decision-making process for management of pediatric patients with spinal deformity. METHODS The literature was reviewed in reference to pediatric deformity evaluation and management. RESULTS Pediatric spinal deformity includes a broad range of disorders with differing causes, natural histories, and treatments. Appropriate categorization of pediatric deformities is an important first step in the clinical decision-making process. An understanding of both nonoperative and operative treatment modalities and their indications is requisite to providing treatment for pediatric patients with spinal deformity. The primary nonoperative treatment modalities include bracing and casting, and the primary operative treatments include nonfusion instrumentation and fusion with or without instrumentation. In this article, we provide a review of pediatric spinal deformity classification and an overview of general treatment principles. CONCLUSION The decision-making process in pediatric deformity begins with appropriate diagnosis and classification of the deformity. Treatment decisions, both nonoperative and operative, are often predicated on the basis of the age of the patient and the natural history of the disorder.

188 Background: The AUA and American Cancer Society both recommend a shared decision-making process between clinicians and patients for prostate cancer screening with PSA testing. Data are limited data regarding patient preferences for PSA evaluation in the United States. We assessed the sociodemographic and clinical characteristics of men who proceeded with or opted out of PSA testing in a nationally representative population-based cohort. Methods: We analyzed male participants from the 2001 to 2008 cycles of the National Health and Nutrition Examination Survey (NHANES) who were 40 years old or older without a history of prostate cancer, recent prostate manipulation, or hormone therapy use (n = 6,032). All men underwent or refused PSA testing after a standardized explanation about prostate cancer screening by a physician. A multivariate logistic regression was conducted after adjusting for survey weights to identify independent sociodemographic and clinical predictors for opting out of PSA testing. Results: Overall, 5% of the study cohort refused PSA testing. The analysis revealed predictors for refusing PSA testing (Table). PSA testing preference was not influenced by a family history of prostate cancer, previous prostate cancer screening, education level, socioeconomic status, insurance status, or tobacco history. There were no significant time trends for PSA testing. Conclusions: Despite equal access to PSA testing in our study, there was unequal utilization. We found that Black men were more likely to refuse PSA testing. Our analysis also suggests that a perception of suboptimal health or uncertain future outlook may discourage men from undergoing PSA evaluation. These patient preferences for PSA evaluation should be factored into the shared decision-making process for prostate cancer screening.

Opinion differs about the role of syndicated columnists in the forming of national opinion and in the decision-making process in the United States. Our columnists have been the subject of pioneering studies, but we have a long way to go before the picture can be called historically complete, scientifically precise, or fully satisfactory for policy-making purposes. What the columnists say is an important chapter in the history of the American public, and history is most useful for critical purposes when written close to the event. The general theory of communication and politics can be refined as the details of the opinion process are more fully known.

The evolution of the referendum institutionalization in the constitutions of the EU states is considered. The peculiarities of its initiation, realization and implementation of results in the "old" and "new" members of the Union are highlighted and analyzed. It is concluded that young democracies are pioneering in using this tool of direct democracy both to legitimize government decisions and to involve citizens in the decision-making process. The history of the introduction of plebiscites into the practice of political processes in European countries shows, that they are closely linked to democratic transit: the later the constitution is adopted, the more opportunities for citizens to use referendums not only to control the legislative process in parliament (support or veto certain decisions, draft laws), but also to formulate an agenda - to propose their own initiatives for consideration by public authorities. Accordingly, there are obvious differences between the referendum practices of the "old" and "new" members of the European Union, since the latter are much more active in using them and give citizens real leverage on public policy by holding plebiscites on popular initiatives.

During foraging, animals decide how long to stay and harvest reward, and then abandon that site and travel with a certain speed to the next reward opportunity. One aspect of this behavior involves decision-making, while the other involves motor-control. A recent theory posits that control of decision-making and movements may be linked via a desire to maximize a single normative utility: the sum of all rewards acquired, minus all efforts expended, divided by time. If this is the case, then the history of rewards, and not just its immediate availability, should dictate how long one decides to stay and harvest reward, and how slowly one travels to the next opportunity. We tested this theory in a series of experiments in which humans used their hand to harvest tokens at a reward patch, and then used their arm to reach toward a subsequent opportunity. Following a history of poor rewards, people not only foraged for a longer period, but also moved slower to the next reward site. Thus, reward history had a consistent effect on both the decision-making process regarding when to abandon a reward site, and the motor control process regarding how fast to move to the next opportunity.
