Demand Unconstraining

Demand unconstrainingis one of the key techniques to the success of revenue management systems. This paper surveys the history of research on unconstraining methods and reviews over 130 references including the latest research works in the area. We discuss the relationship betweencensoreddata unconstraining and forecasting and review five alternative unconstraining approaches. These methods consider data unconstraining in various situations such as single-class, multi-class, and multi-flight. The paper also proposes some future research questions to bridge the gap between theory and applications.

“Apocalyptic Literature” and “Wisdom Literature” are broad designations that represent widely recognized categories of inquiry in the fields of ancient Judaism, early Christianity, and beyond. The relationship between the two has been a prominent topic of study over the last five decades. Beyond their familiar connotations, one finds a complicated and contested relationship in recent scholarship on ancient Jewish and Christian literature. This article attempts to disambiguate both the terms and the recent history of research in order to highlight some of the most important progress made and some of the most promising avenues for future research.

Perception Of Time

Time is a fundamental dimension of human perception, cognition and action, as the perception and cognition of temporal information is essential for everyday activities and survival. Innumerable studies have investigated the perception of time over the last 100 years, but the neural and computational bases for the processing of time remains unknown. First, we present a brief history of research and the methods used in time perception and then discuss the psychophysical approach to time, extant models of time perception, and advancing inconsistencies between each account that this review aims to bridge the gap between. Recent work has advocated a Bayesian approach to time perception. This framework has been applied to both duration and perceived timing, where prior expectations about when a stimulus might occur in the future (prior distribution) are combined with current sensory evidence (likelihood function) in order to generate the perception of temporal properties (posterior distribution). In general, these models predict that the brain uses temporal expectations to bias perception in a way that stimuli are ‘regularized’ i.e. stimuli look more like what has been seen before. Evidence for this framework has been found using human psychophysical testing (experimental methods to quantify behaviour in the perceptual system). Finally, an outlook for how these models can advance future research in temporal perception is discussed.

AbstractMusic has been steadily rising up the historical agenda, a product of the emergence of sound studies, the history of the senses, and a mood of interdisciplinary curiosity. This introductory article offers a critical review of how the relationship between music and politics has featured in extant historical writing, from classic works of political history to the most recent scholarship. It begins by evaluating different approaches that historians have taken to music, summarizes the important shifts in method that have recently taken place, and advocates for a performance-centered, contextualized framework that is attentive to the distinctive features of music as a medium. The second half examines avenues for future research into the historical connections between music and politics, focusing on four thematic areas—the body, emotions, space, and memory—and closes with some overarching reflections on music's use as a tool of power, as well as a challenge to it. Although for reasons of cohesion, this short article focuses primarily on scholarship on Britain and Ireland in the eighteenth and nineteenth centuries, its discussion of theory and methods is intended to be applicable to the study of music and political culture across a broad range of periods and geographies.

This chapter reviews the major methodological and theoretical approaches used in Mining Language, at once concluding the book and gesturing toward future research directions in the fields of history of colonial science and technology and Indigenous Studies. Specifically, it reflects on the relationship between history and literary studies within these intersecting fields. By reflecting on what colonial archives say and do not say, the conclusion argues for the importance of research ethics and methods that confront, acknowledge, and respond to historical silences.

Purpose To report a case of isolated daptomycin-induced acute liver injury without elevations in creatine kinase (CK) levels or kidney dysfunction. Summary A 49-year-old female with a history of pancreatitis, lupus, diabetes, congestive heart failure, hypertension, and chronic pain syndrome presented to the emergency department with alteration in mental status and acute liver failure. The patient had been treated with daptomycin for methicillin-resistant Staphylococcus aureus (MRSA) endocarditis for 3 weeks. After ruling out other possible etiologies, daptomycin was suspected as a cause of acute liver failure. Her liver failure resolved gradually following withdrawal of daptomycin. Conclusion Although hepatic abnormalities caused by daptomycin are rare, a handful of cases with daptomycin-induced liver injury have been reported in the literature. Of note, in most cases, patients on daptomycin therapy developed liver damage with elevations in CK levels. Our case report suggests possible severe liver injury associated with high-dose and long-term daptomycin treatment in the absence of rhabdomyolysis. Future research is warranted to further investigate the relationship between daptomycin use and liver injury, yet it is reasonable to monitor liver function tests at baseline and weekly thereafter along with CK levels, especially in patients requiring long-term daptomycin therapy.

AbstractToxicity is widespread among living organisms, and evolves as a multimodal phenotype. Part of this phenotype is the ability to avoid self-intoxication (autoresistance). Evolving toxin resistance can involve fitness tradeoffs, so autoresistance is often expected to evolve gradually and in tandem with toxicity, resulting in a correlation between the degrees of toxicity and autoresistance among toxic populations. We investigate this correlation in Phyllobates poison frogs, notorious for secreting batrachotoxin (BTX), a potent neurotoxin that targets sodium channels, using ancestral sequence reconstructions of BTX–sensing areas of the muscular voltage-gated sodium channel. Reconstructions suggest that BTX resistance arose at the root of Phyllobates, coinciding with the evolution of BTX secretion. After this event little or no further evolution of autoresistance seems to have occurred, despite large increases in toxicity throughout the history of these frogs. Our results therefore provide no evidence in favor of an evolutionary correlation between toxicity and autoresistance, which conflicts with previous work. Future research on the functional costs and benefits of mutations putatively involved in BTX resistance, as well as their prevalence in natural populations should shed light on the evolutionary mechanisms driving the relationship between toxicity and autoresistance in Phyllobates frogs.

Improve Health

AbstractThe need to develop alternatives to improve health assistance access and qualification was emergent and urgent even before the advent of Covid-19. Such demand is necessary in regard to both public and private systems. In this context, the theme of cost and effectiveness is technically adequate and viable to analyze these alternatives. Analyzing the history of research development on the topic and identifying its gaps is thus an essential step in facing this challenge. Therefore, the objective of this study was to modestly contribute to a bibliometric examination of scientific production based on the theme of cost-effectiveness to guide future research, despite the maturity of the theme, and as well as its future challenges. As a result, several essential aspects of the theoretical approach to the theme were observed, such as its conceptualization, purpose, and objective within public and private institutions, identifying its main authors, universities, reference countries, and funding institutions, authors’ relationship networks, and related themes. One of the most important factors identified is the absence of the theme applied to contemporary topics in health, such as telemedicine, telehealth, robotics, artificial intelligence, new drugs and medicines, and new healthcare protocols.

AbstractThe present article seeks to re-present Karl Barth's exegesis of 1 Kings 13 with additional support that Barth neglected to include. Changes in biblical scholarship over the past few decades have resulted in an environment in which Barth's interpretation may not be as readily rejected as it was in the past. Barth's exegesis of 1 Kings 13 was not accepted among biblical scholars for several reasons. He was thought to be an enemy of historical criticism whose exegetical work was not a serious contribution to biblical studies. Furthermore, he interpreted the chapter holistically at a time when scholars were preoccupied with analytical questions concerning sources and composition. Barth related the chapter to the whole history of the divided kingdom by suggesting that the man of God and the old prophet represent the kingdoms from which they come and that the relationship between the two prophetic figures mirrors the relationship between Israel and Judah as told in Kings. This analogy seemed unlikely to scholars convinced of the fragmentary nature of Kings. The present article begins with an overview of Barth's relationship to modern biblical scholarship followed by a summary presentation of his exegesis of 1 Kings 13. Next, the major objections to Barth's interpretation are critically assessed, and recent research on the chapter is evaluated. Finally, the analogy indicated by Barth is elaborated, so that his interpretation may seem more plausible and future research may benefit from his insights.

Validity and validation have been key issues in language testing. During the past seven decades, researchers have aired different views on validity whose development, can be divided into four stages, namely, the stage of criterion-based approach, the stage of tripartite approach, the stage of unified approach and the stage of argument-based approach. In order to have an informed knowledge of validity theory, this article briefly traces the history of research on validity concepts and the corresponding frameworks of validation. By examining the development of validity and validation, some possible topics for future research are uncovered.

This article discusses the history of investigations into British linear earthworks in the twentieth century. The influence of pre-existing beliefs about the environment of Britain, especially the existence of impassable forest cover, deeply influenced the interpretation of linear monuments and had a lasting effect on the study of these monuments. A brief history of the personalities involved is followed by two case studies of monuments that were believed to be post-Roman in date but are now seen as Iron Age monuments. The implications of the change in the relationship to of the dykes to the landscape is discussed along with potential future research, better informed by an awareness of this confusing tradition of field archaeology.
