A key role in inference is played by randomization, which has been extensively used in clinical trials designs. Randomization is primarily intended to prevent the source of bias in treatment allocation by producing comparable groups. In the frequentist framework of inference, randomization allows also for the use of probability theory to express the likelihood of chance as a source for the difference of end outcome. In the Bayesian framework, its role is more nuanced. The Bayesian analysis of clinical trials can (...) afford a valid rationale for selective controls, pointing out a more limited role for randomization than it is generally accorded. This paper is aimed to offer a view of randomization from the perspective of both frequentist and Bayesian statistics and discussing the role of randomization also in theoretical decision models.

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 47, no. 1. © 2021 by Feminist Studies, Inc. 201 Ileana Nachescu Censoring Anglogynophobia: Reconsidering the Disappearance of the National Alliance of Black Feminists Black women’s activism in the 1970s has often been located in the fissures between the civil rights movement, women’s liberation movement, and Black nationalism—a form of “interstitial feminism,” in the words of Kimberly Springer.1 Providing crucial interventions to disrupt male supremacy and (...) sexism within Black organizations as well as racism and homophobia within feminist organizations, Black feminist politics modeled a “vanguard center” whose liberation signaled the liberation of all.2 The Combahee River Collective’s “Black Feminist Statement” (1977), which has become a classic in women’s, gender, and sexuality studies curricula, encapsulates the power of this transformative image. The Combahee River Collective was not the only Black feminist group active in the second half of the 1970s, of course. The Third World Women’s Alliance (TWWA), founded in 1969, had a vibrant presence on both the East Coast and the West Coast throughout this decade. The National Black Feminist Organization (NBFO), active between 1973 and 1975, mobilized Black women around the country and gave the impetus for the formation of several local chapters. After NBFO ended, the 1. Kimberly Springer, “The Interstitial Politics of Black Feminist Organizations,” Meridians 1, no. 2 (Spring 2001): 156. 2. Benita Roth, Separate Roads to Feminism: Black, Chicana, and White Feminist Movements in America’s Second Wave (Cambridge, MA: Cambridge University Press, 2003), 91. 202 Ileana Nachescu National Alliance of Black Feminists (NABF) became perhaps the bestknown Black women’s organization at the time due to appearances on national television, articles and essays published in multiple Black and feminist venues, and its attempt to build a national organization. In October 1977, NABF’s national conference, “A Meeting of the Minds,” attracted more than two hundred African American women to Chicago for two days in order to discuss their experiences, listen to speakers, and develop an agenda to address the most pressing issues of the day. To this day, the long list of resolutions passed at this conference constitutes the most comprehensive set of political, economic, and cultural demands collectively devised by African American women. Yet, more than four decades later, NABF has disappeared from public consciousness, remembered only by a small group of feminist historians. The erasure of NABF from women’s history and Black history is a puzzle—in part because the organization excelled at the kinds of activities that leave visible traces. In an interview with Kimberly Springer, Combahee River Collective founder Barbara Smith noted that “People who write get far more visibility than those who don’t.”3 But NABF Executive Director Brenda Eichelberger published many essays in regional and national periodicals documenting diverse initiatives by Black feminists in the 1970s. Furthermore, unlike many feminist organizations that did not record their operations or whose records have been lost, NABF intentionally gathered and preserved rich archival materials.4 Using materials from the National Alliance of Black Feminists archives, I suggest that NABF defies many received views about Black feminist activism, and this defiance makes attention to NABF all the more vital to the history of US feminism. By examining NABF’s original theorization of “Anglogynophobia,” Black women’s distrust of and animosity toward white women, I advance a much darker explanation for the 3.

The Body Image Questionnaire-20 (FKB-20) is one of the most applied self-report measures in the context of body image assessment in German-speaking regions. A version of the FKB-20 capturing an ideal concept of body image is also available. A special property of the scale is its high sensitivity for individuals suffering from anorexia nervosa. The present research provided a short version of this scale (for both variants) and examined its validity in a representative sample (N= 2,347) of the German population. (...) We utilized factor analysis methods to identify the optimal short scale of the measure, finding excellent model fit and reliability for a two-factor model (FKB-6) for both real and ideal body image. Both versions of the FKB-6 can be considered invariant across sex and age groups. Good reliability indices were shown for both versions of the FKB-6. The reliability indices were similar to those mentioned in previous studies. Our study also revealed, that large discrepancies between the real and an ideal body image are correlated with somatic and body dysmorphic symptoms. Finally, we provided norm values for comparisons of individual scores with the general population. The FKB-6 is a valid and a reliable measure that economizes assessments by clinicians and researchers. (shrink)

To foster understanding in the psychopathology of patients with anorexia nervosa at the psychological and physiological level, standardized experimental studies on reliable biomarkers are needed, especially due to the lack of disorder-specific samples. To this end, the autonomic nervous system response to a psychosocial stressor was investigated in n = 19 PAN, age, and gender-matched to n = 19 healthy controls. For this purpose, heart rate and heart rate variability parameters were assessed in a cross-sectional study design under two experimental (...) conditions: rest and stress. In addition, psychological indicators of stress were assessed. An 2 × 2 × 8 ANOVA demonstrated similar HR and HRV patterns between PAN and HC at rest. Under stress, PAN demonstrated a blunted HR [condition*time*group: F = 9.326, p = 0.000, η2 = 0.206] and an attenuated HRV response. Significant effects of stress appraisal and BMI on HRV-reactivity were revealed. SA on SDNN = Condition*time*SA = F = 2.676, p = 0.033, η2 = 0.073. BMI on LF/HF-Ratio = Condition*time*BMI = F = 3.339, p = 0.019, η2 = 0.164. Psychological indices suggested higher levels of chronic and appraised stress in PAN relative to HC. Additional analyses demonstrated that ED-symptoms are highly correlated with the latter constructs, as well as with psychological burden, but not with weight. Further, it was shown that abnormalities in reactivity persisted despite normalized ANS activity. Overall, we suggested that besides weight recovery, improvement in stress appraisal could be beneficial for cardiac health. In this light, a combination of therapy and biofeedback training may improve treatment outcomes and regulate stress reactivity. (shrink)

Background: The Self-Regulation of Eating Behavior Questionnaire is an economical way of assessing an individual's self-regulatory abilities regarding eating behavior. Such scales are needed in the German population; therefore, the purpose of the present study was the translation and validation of a German version of the SREBQ.Method: First, we conducted a pilot study after the translation procedure. Second, we assessed the final scale in a representative sample of the German population and its underlying factor structure. Further, we tested for measurement (...) invariance and evaluated the SREBQ's associations with related scales to explore convergent and discriminant validity. Finally, we considered differences in SREBQ based on sociodemographic variables and provided derived reference scores.Results: Factor analysis revealed deficiencies in the original model. Thus, we shortened the scale based on statistical considerations and the adapted version showed improved fit in Confirmatory Factor Analysis and reliability. We also found evidence for partial strict invariance, which means the measure is equivalent for the tested groups of age and gender. Item and scale psychometric properties of the shortened version were satisfactory. In terms of diagnostic validity, it was shown that individuals with higher body mass index have worse self-regulation of eating behavior than those with lower.Conclusion: In sum, the SREBQ evidenced good validity and reliability and is suitable for application in medical, psychological, and nutritional research.

Summary The anniversary of the death of Pietro Tacchini (1838?1905), one of the pioneers of solar physics in Italy, is commemorared by this account of his major creation, the Società degli Spettroscopisti Italiani (1871). Established to promote cooperation among solar spectroscopists engaged in the study of the solar chromosphere, it was the first scientific Society devoted to spectroscopy and its astronomical applications. Its journal, the Memorie, collected most of the important works on solar physics by Angelo Secchi SJ (1818?1878), Tacchini (...) himself, and many other protagonists of the newly born astrophysics. A brief history of the Society and its development draws on many previously unexploited archival sources, in order to show its role in raising astrophysics to the status of a scientific discipline, in the context of the astronomical research of that time in Italy and abroad, especially in the USA.

The paper studies the containment companion of a logic \. This consists of the consequence relation \ which satisfies all the inferences of \, where the variables of the conclusion are contained into those of the set of premises, in case this is not inconsistent. In accordance with the work started in [10], we show that a different generalization of the Płonka sum construction, adapted from algebras to logical matrices, allows to provide a matrix-based semantics for containment logics. In particular, (...) we provide an appropriate completeness theorem for a wide family of containment logics, and we show how to produce a complete Hilbert style axiomatization. (shrink)

In our daily life we develop habits that, being constantly practiced, become part of who we are. Two areas in which we develop habits are the evaluation of sources of food, and the evaluation of sources of happiness. It is my contention that the habits developed in those areas could affect one another. Thus, acquiring good habits in one area is of utmost importance to develop the other one. Conversely, if we develop the bad habit of picky eating this will (...) have as one of its outcomes the development of a bad habit that restricts our openness to rmding avenues for happiness. In order to show how the two habits affect one another, I will use Aristotle's theory of habit as developed in his Nicomachean Ethics. (shrink)

The story of the binding of Isaac, also known as the akedah, has been the subject of many important philosophical commentaries and discussions. One of these is Kierkegaard’s Fear and Trembling, first published in 1843. Comparing Kierkegaard’s characterization of Abraham as the paradigm of the knight of faith with the character of Iphigenia from Euripides’s Iphigenia at Aulis, it becomes apparent that Iphigenia exhibits characteristics that make her fit the same paradigm. In order to account for the behavior of both (...) Abraham and Iphigenia, I use Aristotle’s notion of ἕξις as it appears in Nicomachean Ethics II.5. (shrink)

The Law Most Beautiful and Best: Medical Argument and Magical Rhetoric in Plato’s Laws. By Randall Baldwin Clark (Lanham, MD: Lexington Books, 2003), xiv + 178 pp. $55.00 cloth.

The many ways in which we interact with food, e.g., eating, cooking, purchasing, farming, legislating, etc., are intersected by ethics and politics. The terms of our interactions with food are dictated in a significant way by how we understand its metaphysical underpinnings; that is to say, by how we define “food.” When food is understood as nothing more than it becomes easier to dismiss our political and ethical obligations since, after all, food is only a thing. This obscures the others (...) who make our interactions with food possible, and who are affected by our choices and those of our communities. In order to revitalize our engagement with the ethical and political responsibilities that we both inherit and produce in our interactions with food, it is helpful to refocus our understanding of what food actually is. I propose that food is better understood as a transformative . Building on metaphysical theories by Aristotle and Emmanuel Levinas, I explain this new understanding of food, and use examples to show how this view of food enhances our political and ethical responsibilities.

The logic DAI of demodalised analytic implication has been introduced by J.M. Dunn as a variation on a time-honoured logical system by C.I. Lewis’ student W.T. Parry. The main tenet underlying this logic is that no implication can be valid unless its consequent is “analytically contained” in its antecedent. DAI has been investigated both proof-theoretically and model-theoretically, but no study so far has focussed on DAI from the viewpoint of abstract algebraic logic. We provide several different algebraic semantics for DAI, (...) showing their equivalence with the known semantics by Dunn and Epstein. We also show that DAI is algebraisable and we identify its equivalent quasivariety semantics. This class turns out to be a linguistic and axiomatic expansion of involutive bisemilattices, a subquasivariety of which forms the algebraic counterpart of Paraconsistent Weak Kleene logic. This fact sheds further light on the relationship between containment logics and logics of nonsense. (shrink)

Paraconsistent Weak Kleene Logic is the 3-valued propositional logic defined on the weak Kleene tables and with two designated values. Most of the existing proof systems for PWK are characterised by the presence of linguistic restrictions on some of their rules. This feature can be seen as a shortcoming. We provide a cut-free calculus for PWK that is devoid of such provisos. Moreover, we introduce a Priest-style tableaux calculus for PWK.

"This paper builds on John Dewey’s views on interactions to suggest pathways for enriching the study of philosophy. Along with the notions of body-mind and organism-environment transactions, interactions are part of a philosophical project with transformative implications for education as well. The first part of the paper will contextualize Dewey’s discussion of interactions with regard to his philosophy of experience and democratic theory. The second one will propose two criteria with regard to enriching philosophical training in ways that engage the (...) mind and the body - increasing sociocultural awareness and generating integrative learning experiences – and will add a few examples of how the study of philosophy could benefit from applying an interactionist perspective. Keywords: education, experience, interaction, philosophy, John Dewey. ". (shrink)

El artículo propone un análisis del tratamiento kantiano de la �Tercera antinomia de la razón pura� (en la que se examina la posibilidad de conciliar la libertad trascendental con el determinismo natural), a fin de mostrar el carácter infundado de aquella interpretación que sostiene que la resolución crítica de dicha antinomia supone un desplazamiento respecto de los términos cosmológicos en los que el conflicto es planteado originariamente. A través de un análisis pormenorizado de las fuentes, procuraremos establecer que el conflicto (...) analizado en la �Tercera antinomia� no es de carácter exclusivamente cosmológico, sino que constituye asimismo �y en igual medida� un conflicto práctico y, en segundo lugar, que la solución crítica no es desarrollada en términos exclusivamente prácticos, sino que involucra asimismo aspectos directamente vinculados con la cuestión cosmológica inicialmente formulada.

Las observaciones que Kant formula en sus obras críticas acerca de la existencia de la cosa en sí han dado lugar a importantes objeciones y agudas discusiones entre los intérpretes. En este trabajo proponemos una reflexión acerca de la posibilidad de establecer el estatus epistemológico correspondiente a dichas observaciones, haciendo uso del concepto kantiano de creencia doctrinal.

The aim of this article is to discuss pure variable inclusion logics, that is, logical systems where valid entailments require that the propositional variables occurring in the conclusion are included among those appearing in the premises, or vice versa. We study the subsystems of Classical Logic satisfying these requirements and assess the extent to which it is possible to characterise them by means of a single logical matrix. In addition, we semantically describe both of these companions to Classical Logic in (...) terms of appropriate matrix bundles and as semilattice-based logics, showing that the notion of consequence in these logics can be interpreted in terms of truth (or non-falsity) and meaningfulness (or meaninglessness) preservation. Finally, we use Płonka sums of matrices to investigate the pure variable inclusion companions of an arbitrary finitary logic. -/- . (shrink)

This article deals mainly with problems of cultural/transcultural translation between the Quechua and Spanish cultures, analysing these on the basis of some ideas by Juri Lotman and Peeter Torop. The process of translation implies considering the Quechua semiosphere’s internal borders as well as the external borders related to the cultures that existed at the time of Tahuantin Suyo, and all changes that have come from the Spanish conquest of Latin America. In the case of the Quechua culture, the problems are (...) numerous and conflicting in several dimensions. First of all, Quechua is an agglutinating language that creates problems for translation into a flexional language such as Spanish. Secondly, and more importantly, there exists a mythopoetical model of the world that has been built in this culture, which does not use concepts of rational logic, but poetic images integrated into mythical thinking: it represents a different cognitive pattern. Thirdly, the presence of the logic of the concrete in Quechua culture, articulated with the mythopoetical model, makes translation from Western abstract formal logic difficult. Reflections on these issues provide new analytical possibilities. (shrink)

The concept of Transcendental Object either refers, in the framework of the Critic of Pure Reason, to the cause or foundation of external phenomena, or, on the contrary, to the concept of an object in general as it is thought by the conscience so as to guarantee the objective validity of its representations.

In this paper we investigate AGM belief contraction operators by using the tools of algebraic logic. We generalize the notion of contraction to arbitrary finitary propositional logics, and we show how to switch from a syntactic-based approach to a semantic one. This allows to build a solid bridge between the validity of AGM postulates in a propositional logic and specific algebraic properties of its intended algebraic counterpart. Such a connection deserves particular attention when we deal with maxichoice contractions, as studied (...) in the final part of the paper. (shrink)
