A two-stage logistic regression model for analyzing inter-rater agreement

Studies of agreement commonly occur in psychiatric research. For example, researchers are often interested in the agreement among radiologists in their review of brain scans of elderly patients with dementia or in the agreement among multiple informant reports of psychopathology in children. In this paper, we consider the agreement between two raters when rating a dichotomous outcome (e.g., presence or absence of psychopathology). In particular, we consider logistic regression models that allow agreement to depend on both rater- and subject-level covariates. Logistic regression has been proposed as a simple method for identifying covariates that are predictive of agreement (Coughlin et al., 1992). However, this approach is problematic since it does not take account of agreement due to chance alone. As a result, a spurious association between the probability (or odds) of agreement and a covariate could arise due entirely to chance agreement. That is, if the prevalence of the dichotomous outcome varies among subgroups of the population, then covariates that identify the subgroups may appear to be predictive of agreement. In this paper we propose a modification to the standard logistic regression model in order to take proper account of chance agreement. An attractive feature of the proposed method is that it can be easily implemented using existing statistical software for logistic regression. The proposed method is motivated by data from the Connecticut Child Study (Zahner et al., 1992) on the agreement among parent and teacher reports of psychopathology in children. In this study, parents and teachers provide dichotomous assessments of a child's psychopathology and it is of interest to examine whether agreement among the parent and teacher reports is related to the age and gender of the child and to the time elapsed between parent and teacher assessments of the child.The authors thank the Associate Editor and the referees for their helpful comments and suggestions.

Reach and posture hand preferences during arboreal feeding in Sifakas (Propithecus sp.): a test of the postural origins theory of behavioral lateralization

Sixteen sifakas (11 Propithecus verreauxi coquereli, 2 Propithecus verreauxi verreauxi form majori, and 3 Propithecus tattersalli) were videotaped as they fed on leaves in an arboreal context. The hand used to feed and the hand used to maintain postural stability was coded. For each subject, the lateral bias of the hand used to feed was opposite the hand used in postural support. Seven sifakas displayed no bias for feeding or posture-related hand use, 7 sifakas displayed significant feeding-related reach preferences for pulling branches to the mouth (5 left- and 2 right-hand preferences), and 9 sifakas exhibited significant hand preferences for postural support (2 left-, 7 right-hand preferent). Although these data do not strongly support the postural origins theory of behavioral lateralization, the modal preference pattern for sifakas that displayed significant hand preferences for posture and feeding involve a left bias for feeding and a right bias for postural support. s reserved).     

Weal and Woe: Suffering,Sociology, and the Emotions of Julian of Norwich

The power which narratives of mystical experience exert on our thinking derives from the central place of emotions within them. These narratives are crucial to the phenomenon of healing: not as cure, but as a means of accepting, understanding, and minimising suffering. Contemporary religious thought draws heavily on social theory but this paper shows not only that mystical emotions have escaped the attention of sociology, but also that sociology is unable to provide an adequate account of them or of their place in overcoming pain of all kinds. It does so by comparing three very different books about the emotions: Deborah Lupton's The Emotional Self (1998), Jack Barbalet's Emotions, Social Theory and Social Structure (1998), and the fourteenth century Revelations of Divine Love by Julian of Norwich. The last of these illuminates what the other two call the extra-discursive, embodied and unconscious dimensions of emotions. The first part of the paper makes a general comparison and the second turns to a range of specific emotions: shame and guilt, sorrow and depression, anger, fear, and anxiety, and the positive emotions of joy, love, and desire. This comparison helps explain how people live with chronic suffering and transcend it. It also shows that sociology, by making society itself a thing and elevating it to God-like status, cannot provide the critique of theology which was one of its original intentions, nor fully account for the healing influence of mystical phenomena.     

Joseph Heller's Jewish War Novel Catch-22

Joseph Heller's Catch-22 (1961) is considered one of the most important American novels of the twentieth century. It was a massive bestseller that sold over 10 million copies, and it introduced a new phrase into the English language for an unsolvable conundrum or paradox. Catch-22 was groundbreaking because it was the first broadly successful American novel that offered a post-modern, satirical take on the Second World War. Ostensibly the novel had nothing whatsoever Jewish about it beyond the ethnicity of its author. Instead it was about the Assyrian/Armenian protagonist, Yossarian, a USAAF bombardier in the European theatre. As I will argue, while outwardly the novel aims to represent the war and the protagonist, Yossarian, as American rather than Jewish, the work is, in fact, packed with signs that it is about a Jewish airman confronting the Holocaust. Heller's attempt to hide this was part of a tradition established by Jewish authors in the post-war years who sought to distance themselves from their ethnicity in order to speak to “universal” themes of rebellion. However, to overlook the “Jewish” semiotics of Catch-22 is to miss many of its major themes. I am thus offering a reading of the novel that will delineate what it tells us about the post-war Jewish life in America.     

Does the consequence argument beg the question?

The Consequence Argument has elicited various responses, ranging from acceptance as obviously right to rejection as obviously problematic in one way or another. Here we wish to focus on one specific response, according to which the Consequence Argument begs the question. This is a serious accusation that has not yet been adequately rebutted, and we aim to remedy that in what follows. We begin by giving a formulation of the Consequence Argument. We also offer some tentative proposals about the nature of begging the question. Although the charge of begging the question is frequently made in philosophy, it is surprisingly difficult to pin down the precise nature of this dialectical infelicity (or family of such infelicities). Thus we offer some new proposals about the nature of begging the question with an eye to understanding what is going on in central cases in which the charge is legitimately made. We then defend the Consequence Argument against the charge that it begs the question, so construed. We contend that, whatever the other liabilities of the argument may be, it does not beg the question against the compatibilist.     

Relational and item-specific influences on generate–recognize processes in recall

The generate–recognize model and the relational–item-specific distinction are two approaches to explaining recall. In this study, we consider the two approaches in concert. Following Jacoby and Hollingshead (Journal of Memory and Language 29:433–454, 1990), we implemented a production task and a recognition task following production (1) to evaluate whether generation and recognition components were evident in cued recall and (2) to gauge the effects of relational and item-specific processing on these components. An encoding task designed to augment item-specific processing (anagram-transposition) produced a benefit on the recognition component (Experiments 1–3) but no significant benefit on the generation component (Experiments 1–3), in the context of a significant benefit to cued recall. By contrast, an encoding task designed to augment relational processing (category-sorting) did produce a benefit on the generation component (Experiment 3). These results converge on the idea that in recall, item-specific processing impacts a recognition component, whereas relational processing impacts a generation component.     

Military Marriages: The Aftermath of Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) Deployments

An examination of how members of military marriages were affected by and adapted to OIF/OEF deployment found three themes: communicating to stay connected, emotional and marital intimacy, and managing change. The findings demonstrate the nuanced and subtle nature of deployment-related challenges. While open and frequent communication was important in the adaptation process, communication was not synonymous with transparency. Unshared stories created a void that prevented couples from confiding in and supporting their partners. Although wives maintained their marriages by restraining sexual desires and over-extending their responsibilities post-deployment, these behaviors had a negative effect on marital quality. Clinical and research implications are discussed.
