Formal Contexts, Formal Concept Analysis, and Galois Connections

Formal concept analysis (FCA) is built on a special type of Galois connections called polarities. We present new results in formal concept analysis and in Galois connections by presenting new Galois connection results and then applying these to formal concept analysis. We also approach FCA from the perspective of collections of formal contexts. Usually, when doing FCA, a formal context is fixed. We are interested in comparing formal contexts and asking what criteria should be used when determining when one formal context is better than another formal context. Interestingly, we address this issue by studying sets of polarities.Comment: In Proceedings Festschrift for Dave Schmidt, arXiv:1309.455

Go-ahead men: Yankee Westerners test masculine bonds in the early American republic

Colonial New England fathers normally launched sons\u27 careers, often aided by other male relatives. However, economic developments in the early American republic rendered sons\u27 expectations less sure even as Americans began celebrating the concept of the self-made man and pressured young men to distinguish themselves. Even worse, they asserted that success or failure signaled more about the man than about his particular circumstances. This study delves into some close male relationships through which were negotiated these tensions between cultural expectations and reality. Scholars describe the rise of a distinctly Northern, middle-class manhood, but this project isolates how the relationships that undergirded it functioned for individual men propelled toward imagined opportunities in the emerging West, where the fabled Yankee go-ahead might achieve its purest expression. It corrects an overemphasis on Eastern urban centers and also challenges a prevailing view that a cultural celebration of individualism reflecting broad changes underway was exemplified by hordes of ambitious, competitive young men eager to try their hands at self-fashioning. If this research is indicative, often a circle of close male associates surrounded and protected aspiring men from suffering the full potential brunt of the competitive marketplace. Three chapters examine case studies involving Northwest Territory Judge John Cleves Symmes, Western Reserve abolitionist Joshua Giddings, and Bleeding Kansas participant Oscar Learnard. All three had New England backgrounds and ideas about what roles close male associates might play in the lives of young men hoping for a launch into adulthood. They also had a boundless supply of ambition and viewed the developing West as the place to unleash it: they were go-ahead men

In Adults with Eating Disorders, Is the Use of Online-based Cognitive Behavioral Therapy Effective in Reducing Eating Disorder Psychopathologies?

OBJECTIVE: The objective of this selective evidence based medicine (EBM) review is to determine whether “In adults with eating disorders, is the use of online-based cognitive behavioral therapy (CBT) effective in reducing eating disorder (ED) psychopathologies?” STUDY DESIGN: Systematic review of three peer-reviewed studies published between 2015 and 2017. DATA SOURCES: Articles included are data from three randomized controlled trials (RCTs) found via PubMed and Cochrane Collaboration database sites in the English language. OUTCOME(S) MEASURED: The outcomes measured were eating disorder psychopathologies using a global score obtained from the Eating Disorders Examination Questionnaire (EDE-Q). The global score is comprised of four categorical subsets relative to the symptoms of eating disorders: restraint, eating concern, weight concern and shape concern. RESULTS: All studies found large within-group effect sizes for experimental groups, indicating symptom reduction after online-CBT. The first study had a large effect size (d = 0.83) with a statistically significant (p \u3c 0.001) reduction in EDE-Q scores. Between-group analysis showed moderate treatment effect (d = 0.54) (Strandskov SW, Ghaderi A, Andersson H, et al. Behav Ther. 2017;48(5):624-637. doi: S0005-7894(17)30023-0 [pii].). The second indicates that both experimental and control groups had lower EDE-Q scores following the 15 week trial (p \u3c0.001); treatment effect was large for the experimental group (d = 0.82) and moderate for the control group (d = 0.43)( ter Huurne ED, de Haan HA, Postel MG, van der Palen J, VanDerNagel JE, DeJong CA. J Med Internet Res. 2015;17(6):e152. doi: 10.2196/jmir.3946 [doi].). The third RCT found within-treatment group effect size was large (d = 1.33), with small effect size (d=0.25) for the waitlisted group. Between-group comparison was also large (d = 1.18) ( Wagner B, Nagl M, Dolemeyer R, et al. Behav Ther. 2016;47(4):500-514. doi: 10.1016/j.beth.2016.01.006 [doi]). CONCLUSIONS: The findings of all three RCTs are supportive of the use of online-based cognitive behavioral therapy (CBT) in efficaciously reducing eating disorder psychopathology

Dual attachment pairs in categorically-algebraic topology

[EN] The paper is a continuation of our study on developing a new approach to (lattice-valued) topological structures, which relies on category theory and universal algebra, and which is called categorically-algebraic (catalg) topology. The new framework is used to build a topological setting, based in a catalg extension of the set-theoretic membership relation "e" called dual attachment, thereby dualizing the notion of attachment introduced by the authors earlier. Following the recent interest of the fuzzy community in topological systems of S. Vickers, we clarify completely relationships between these structures and (dual) attachment, showing that unlike the former, the latter have no inherent topology, but are capable of providing a natural transformation between two topological theories. We also outline a more general setting for developing the attachment theory, motivated by the concept of (L,M)-fuzzy topological space of T. Kubiak and A. Sostak.This research was partially supported by the ESF Project of the University of Latvia No. 2009/0223/1DP/1.1.1.2.0/09/APIA/VIAA/008.Frascella, A.; Guido, C.; Solovyov, SA. (2011).
