The Museum Experience Revisited
The first book to take a \"visitor's eye view\" of the museum visit when it was first published in 1992, The Museum Experience revolutionized the way museum professionals understand their constituents. Falk and Dierking have updated this essential reference, incorporating advances in research, theory, and practice in the museum field over the last twenty years. Written in clear, non-technical style, The Museum Experience Revisited paints a thorough picture of why people go to museums, what they do there, how they learn, and what museum practitioners can do to enhance these experiences.

The Cambridge companion to Rudyard Kipling
\"Rudyard Kipling (1865-1936) is among the most popular, acclaimed and controversial of writers in English. His books have sold in great numbers, and he remains the youngest writer to have won the Nobel Prize in Literature. Many associate Kipling with poems such as 'If-', his novel Kim, his pioneering use of the short story form and such works for children as the Just So Stories. For others, though, Kipling is the very symbol of the British Empire and a belligerent approach to other peoples and races. This Companion explores Kipling's main themes and texts, the different genres in which he worked and the various phases of his career. It also examines the 'afterlives' of his texts in postcolonial writing and through adaptations of his work. With a chronology and guide to further reading, this book serves as a useful introduction for students of literature and of Empire and its after effects\"-- Provided by publisher.

Human-algorithm teaming in face recognition: How algorithm outcomes cognitively bias human decision-making
In face recognition applications, humans often team with algorithms, reviewing algorithm results to make an identity decision. However, few studies have explicitly measured how algorithms influence human face matching performance. One study that did examine this interaction found a concerning deterioration of human accuracy in the presence of algorithm errors. We conducted an experiment to examine how prior face identity decisions influence subsequent human judgements about face similarity. 376 volunteers were asked to rate the similarity of face pairs along a scale. Volunteers performing the task were told that they were reviewing identity decisions made by different sources, either a computer or human, or were told to make their own judgement without prior information. Replicating past results, we found that prior identity decisions, presented as labels, influenced volunteers' own identity judgements. We extend these results as follows. First, we show that the influence of identity decision labels was independent of indicated decision source (human or computer) despite volunteers' greater distrust of human identification ability. Second, applying a signal detection theory framework, we show that prior identity decision labels did not reduce volunteers' attention to the face pair. Discrimination performance was the same with and without the labels. Instead, prior identity decision labels altered volunteers' internal criterion used to judge a face pair as \"matching\" or \"non-matching\". This shifted volunteers' face pair similarity judgements by a full step along the response scale. Our work shows how human face matching is affected by prior identity decision labels and we discuss how this may limit the total accuracy of human-algorithm teams performing face matching tasks.

COVID-19 masks increase the influence of face recognition algorithm decisions on human decisions in unfamiliar face matching
Face masks, recently adopted to reduce the spread of COVID-19, have had the unintended consequence of increasing the difficulty of face recognition. In security applications, face recognition algorithms are used to identify individuals and present results for human review. This combination of human and algorithm capabilities, known as human-algorithm teaming, is intended to improve total system performance. However, prior work has shown that human judgments of face pair similarity-confidence can be biased by an algorithm’s decision even in the case of an error by that algorithm. This can reduce team effectiveness, particularly for difficult face pairs. We conducted two studies to examine whether face masks, now routinely present in security applications, impact the degree to which this cognitive bias is experienced by humans. We first compared the influence of algorithm’s decisions on human similarity-confidence ratings in the presence and absence of face masks and found that face masks more than doubled the influence of algorithm decisions on human similarity-confidence ratings. We then investigated if this increase in cognitive bias was dependent on perceived algorithm accuracy by also presenting algorithm accuracy rates in the presence of face masks. We found that making humans aware of the potential for algorithm errors mitigated the increase in cognitive bias due to face masks. Our findings suggest that humans reviewing face recognition algorithm decisions should be made aware of the potential for algorithm errors to improve human-algorithm team performance.

Strategies for the production of dsRNA biocontrols as alternatives to chemical pesticides
Current crop pest control strategies rely on insecticidal and fungicidal sprays, plant genetic resistance, transgenes and agricultural practices. However, many insects, plant viruses, and fungi have no current means of control or have developed resistance against traditional pesticides. dsRNA is emerging as a novel sustainable method of plant protection as an alternative to traditional chemical pesticides. The successful commercialisation of dsRNA based biocontrols for effective pest management strategies requires the economical production of large quantities of dsRNA combined with suitable delivery methods to ensure RNAi efficacy against the target pest. A number of methods exist for the production and delivery of dsRNA based biocontrols and here we review alternative methods currently employed and emerging new approaches for their production. Additionally, we highlight potential challenges that will need to be addressed prior to widespread adoption of dsRNA biocontrols as novel sustainable alternatives to traditional chemical pesticides.

A crude look at the whole : the science of complex systems in business, life, and society
\"Imagine trying to understand a stained glass window by breaking it into pieces and examining it one shard at a time. While you could probably learn a lot about each piece, you would have no idea about what the entire picture looks like. This is reductionism--the idea that to understand the world we only need to study its pieces--and it is how most social scientists approach their work. In [this book], social scientist and economist John H. Miller shows why we need to start looking at whole pictures. For one thing, whether we are talking about stock markets, computer networks, or biological organisms, individual parts only make sense when we remember that they are part of larger wholes. And perhaps more importantly, those wholes can take on behaviors that are strikingly different from that of their pieces\"--Amazon.com.

Gastrointestinal conditions related to tooth wear
Gastro-oesophageal reflux disease (GORD) is a relatively common condition that occurs in adults and less commonly in children. It develops when the reflux of stomach contents into the oesophagus causes troublesome symptoms and/or complications. Signs and symptoms include heartburn, retrosternal discomfort, epigastric pain and hoarseness, dental erosion, chronic cough, burning mouth syndrome, halitosis and laryngitis. A proportion of patients will, however, have silent reflux. Strongly associated risk factors include family history, age, hiatus hernia, obesity and neurological conditions, such as cerebral palsy. There are different treatment options which may be considered for GORD, consisting of conservative, medical and surgical therapy. Dentists should be aware of the symptoms of GORD and dental signs of intrinsic erosion indicative of possible GORD so that they can question patients about this and, if appropriate, initiate a referral to a general medical practitioner.Key pointsDetails the common signs and symptoms of gastro-oesophageal reflux disease (GORD) that dentists should be aware of.The principle causes of GORD are sphincter incompetence, increased gastric pressure and increased gastric volume. There are a number of medical, diet and lifestyle risk factors which contribute to these causes.Management options of GORD consist of conservative, medical and surgical therapy. Dentists should refer patients to their general medical practitioner if undiagnosed GORD is suspected.
