The belief that being high is a natural part of your personality predicts an increase in manic symptoms over time in bipolar disorder
No full textBackground: several psychological models of bipolar disorder propose that certain types of appraisals can lead to increases in manic symptoms.Aims: We tested whether the belief that being ‘high’ is a natural part of one’s personality correlates with manic symptoms four months later when controlling for manic symptoms at baseline. Method: a prospective four-month follow-up design using self-report measures. Forty people with a diagnosis of bipolar disorder completed a measure of manic symptoms, a measure of appraisals associated with bipolar disorder, and a single-item measure, “To what extent do you feel like being ‘high’ is a natural part of your personality”, at baseline and follow up.Results: the single-item measure showed modest stability over time and construct validity in its correlation with a standardised measure of appraisals in bipolar disorder. As predicted, the single-item measure correlated with manic symptoms at follow up when controlling for manic symptoms at baseline.Conclusions: the belief that being ‘high’ is a natural part of one’s personality is a potential predictor of manic symptoms. Further research needs to study the potential mediating mechanisms such as activating behaviours, and control for indicators of the bipolar endophenotype
Preface
No full textOn Friday 24th May 2013, William T. Powers, the founder of perceptual control theory (PCT), sadly passed away. This book is dedicated to him. I owe him a debt of gratitude. Without his scientific discoveries - my work, my world, and my life, would not make quite as much sense as they do today. Many of my colleagues have had a similar loss. And because Bill continued to be so generous with his time, patient in the face of persistent questions, and crystal clear in his reasoning, the loss was that much greater for all of us. There will no doubt be a story of Bill Powers' incredible life as an engineer, inventor, scientist, mentor, friend, father, brother, and son, but this book is not that book. This is the book that he wanted written by the many people with whom he had shared his vision. Each of them had gone on to share, test, or use his ideas in very different ways, in diverse academic fields, all with Bill's support and of course, feedback. I must particularly thank Alice Powers McElhone, Bill's sister, who through her business, Benchmark Publications, ensured the continued publication of Behavior: The Control of Perception, Bill's first book, as well as the publication of his subsequent works, Making Sense of Behavior and Living Control Systems I, II, and III. From 2013 to 2018, Alice nearly brought the publication of this final book in the Living Control Systems series to completion. We are extremely grateful to Elsevier for taking her good work to the finish line in time for her to witness the fruit of her labors
Ten vital elements of perceptual control theory, tracing the pathway from implicit influence to scientific advance.
No full textThe central tenet of Perceptual Control Theory (PCT) is that ‘behavior is the control of perception’. From this tenet, a series of further elements are utiized to provide the necessary conceptual and mathematical detail for building and testing functional models of the behavior of humans, animals and purposeful machines. This chapter traces the elements of PCT, and their empirical scrutiny and critique, across multiple scientific disciplines to converge on a contemporary evaluation of the scientific status of PCT as an interdisciplinary theory of behavior. The chapter concludes with key recommendations for future research and the development of the theory
Method of Levels Therapy
No full textMethod of Levels (MOL) is a psychological therapy based on perceptual control theory. MOL involves the therapist asking curious questions to help the client talk freely and openly about a problem to explore their own solutions. MOL helps a client to shift and sustain attention on the source of conflict between important life goals. MOL has unique features that make it particularly flexible, accessible and efficient. It is transdiagnostic and can be applied unchanged across a range of presenting problems and psychiatric diagnoses. Clients are in control of MOL. They can schedule appointments to suit them or their institution (e.g. schools, wards, prisons), they can choose their own problem to focus on for each session, and they can continue the intervention until they perceive that they no longer need it. We explain the theory and practice of MOL, its history, and its current empirical status

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
