The current chapter focuses on basic properties of communication that inform the ways that the study of communication and the study of relationships intersect. These properties include interdependence (the idea that messages simultaneously influence and are influenced by messages that precede and follow them), reflexivity (the notion that communication creates and is constrained by structure), complexity (the concept that communication conveys multiple messages and functions at different levels of analysis), ambiguity (the notion that any given message has various meanings), and indeterminancy (the idea that messages can have multiple and diverse outcomes on relationships). Research on relationship narratives, message features, multiple goals, and message processing, among other topics, is reviewed and challenges for researchers who study communication and relationships are discussed.

A severe earthquake/hurricane has caused devastation to a wide area. Nearly all local infrastructure was damaged, and it will take time to restore function. Several patients arrive days into the deployment to the area. At your medical tent, a pair of patients arrive with complaints of hyperglycemia due to not being able to take their medication and use their insulin, as well as not being able to contact their primary care doctor. One patient is mildly hyperglycemic and can be treated and released. The other patient has developed DKA and must be managed. The patient with DKA is treated with insulin and transferred to a local hospital for ongoing care.

Which of the following is associated with increased risk for primary polydipsia?

Which of the following are NOT associated with myocarditis?

In this scenario a 50-year-old male is brought in from the bus station where he was found sleeping on a covered park bench during a severe winter storm. He arrives obtunded with limited history, severely hypothermic (core temperature of 26°C or 78.8°F) and bradycardic in slow atrial fibrillation. The patient decompensates and suffers a v-fib arrest, requires volume resuscitation, active rewarming in addition to typical ACLS measures. If such measures are taken, then the patient will have return of spontaneous circulation, at which point the team will have the opportunity to contact either their institution’s cardiopulmonary bypass personnel or contact the nearest center with this capability.

The early nineteenth century, approximately 1800–48, is the focus of this chapter. Through consideration of historical sources, it enters the early nineteenth-century Viennese home, finding out what was played, who was playing, with what skill and why. It examines the centrality of the piano and the string quartet and the identity and status of musical dilettantes.

This chapter considers the historical pictures of international systems and international society that Barry Buzan has drawn: International Systems in World History with Richard Little, covering both ancient and modern systems; The Great Transformation with George Lawson, which more closely treats the nineteenth-century system; and Making Global Society, which historicizes the emergence and structure of the contemporary global order. It places them in the tradition of treating international society as a historical subject, a tradition that began with the Gottingen historians in the eighteenth century, and also in the context of historical method, distinguishing between synthetic history and ‘world history’/historical evolutionism as forms of explanatory history. It considers the requirements of each type of history and how closely Buzan’s efforts conform to each. Considering Buzan’s efforts as models of explanatory history, it proposes the requirements of explanatory history with regard to international historical subjects.

Meta-analyses of symptom-focused medication management suggest that impulsive and behavioral dysregulation in borderline personality disorder (BPD) is best treated by which of the following classes of psychotropics?

In this chapter I focus on the nature of theories in the social sciences, some philosophy of science behind the validation of theories (e.g., falsifiability, approaches to deciding the value of evidence for/against a theory), and some issues to consider with respect to the research process and theory development and evaluation. I discuss the value of deconstructing theories to assess their core and auxiliary assumptions and determine aspects of a theory that have yet to be examined. I also discuss modern approaches to assess the evidentiary value of this body of research. I suggest that in our interdisciplinary field, researchers should consider generating hypotheses, as well as research explorations, through carefully evaluating and questioning the assumptions of the theories typically applied in the study of personal relationships. This discussion includes the use of modern approaches such as computational models. The overarching theme of the chapter is that as a field we need to evaluate and develop our theories using some recommendations put forward for decades combined with recently developed techniques in order to advance our theories beyond vague verbal statements that are interesting yet not precise to theories that allow for more consistent deductions of specific hypotheses.

In the aftermath of a tornado, a 35-year-old man with a history of recurrent deep vein thromboses, on Eliquis for anticoagulation, suffers a severe chain saw injury while clearing debris. The chain saw strikes his left midthigh, causing substantial hemorrhage and limb-threatening trauma. Despite prompt EMS intervention, including tourniquet application, IV fluid resuscitation, and pain management, the patient arrives at a rural emergency department in critical condition with hypotension, tachycardia, and significant pain. The nearest surgical facility is an hour away, and helicopter transport is not feasible due to weather conditions. In the emergency department, the trauma team must navigate the complexities of resuscitation, including the challenges of reversing anticoagulation, administering uncrossmatched blood, and managing the time-sensitive issue of tourniquet removal.
