The problem of construction of self-adjoint Hamiltonian for quantum system consisting of three pointlike interacting particles (two fermions with mass 1 plus a particle of another nature with mass m>0) was studied in many works. In most of these works, a family of one-parametric symmetrical operators {Hε,ε∈ℝ1} is considered as such Hamiltonians. In addition, the question about the self-adjointness of Hε is equivalent to the one concerning the self-adjointness of some auxiliary operators {𝒯l,l=0,1,…} acting in the space L2(ℝ+1,r2dr). In this work, we establish a simple general criterion of self-adjointness for operators 𝒯l and apply it to the cases l=0 and l=1. It turns out that the operator 𝒯l=0 is self-adjoint for any m, while the operator 𝒯l=1 is self-adjoint for m>m0, where the value of m0 is given explicitly in the paper.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.

This concluding chapter charts the continuing significance of the early postwar moment in Olson’s later work, particularly The Maximus Poems. The philosophical and political concerns of the American avant-garde between 1946 and 1951 play out across The Maximus Poems just as they inform later American art practices. The search of the early postwar American independent left for a source of political action rooted in the embodied individual is seen, on the one hand, to have been personified in the figure of Maximus. At the same time, Maximus’s radical ‘practice of the self’ charts a sophisticated alternative to the Enlightenment humanist subject widely critiqued in the United States in the immediate postwar period.

This chapter examines the eight female characters inCompany, what they do in the musical, and how they function in the show’s dramaturgy, and argues that they elicit the quintessential challenge of analyzing musical theater from a feminist perspective. On the one hand, the women tend to be stereotypically, even msogynistically portrayed. On the other hand, each character offers the actor a tremendous performance opportunity in portraying a complicated psychology, primarily communicated through richly expressive music and sophisticated lyrics. In this groundbreaking 1970 ensemble musical about a bachelor’s encounters with five married couples and three girlfriends, Sondheim’s female characters occupy a striking range of types within one show. From the bitter, acerbic, thrice-married Joanne to the reluctant bride-to-be Amy, and from the self-described “dumb” “stewardess” April to the free-spirited Marta,Company’s eight women are distillations of femininity, precisely sketched in the short, singular scenes in which they appear.

The phenomenon of quantum erasure exposed a remarkable ambiguity in the interpretation of quantum entanglement. On the one hand, the data is compatible with the possibility of arrow-of-time violations. On the other hand, it is also possible that temporal non-locality is an artifact of post-selection. Twenty years later, this problem can be solved with a quantum monogamy experiment, in which four entangled quanta are measured in a delayed-choice arrangement. If Bell violations can be recovered from a “monogamous” quantum system, then the arrow of time is obeyed at the quantum level.

Confucian mysticism is a subfield in academic areas of study including Chinese thought, Chinese religions, Confucian studies, and comparative mysticism. Important topics examined in this subfield include, first, a view of the human self that is fundamentally relational, both in an interpersonal sense and because Confucians presuppose various correlations and an integration between, on the one hand, the matter–energy, capacities, processes, and activities comprising the self and, on the other, the elements, forces, patterns, and processes of the world it inhabits. One paradigmatic way Confucians conceptualize the interrelation between the self and the cosmos is their idea and ideal of the “unity of Heaven and humanity.” The Confucian mystical self, provided failings such as unbalanced emotions, selfish desires, and self-centeredness are effectively curtailed, contributes vitally to, because of its profound reverence for life, the generative and life-sustaining process of change that pervades and animates the cosmos. Second, practitioners use various techniques of religious praxis in combination to form multifaceted training regimens aimed at self-cultivation and self-transformation. Examples include a form of meditation called “quiet-sitting,” rituals, textual study, “investigating things,” self-examination and self-monitoring, filial piety, and “reverent attentiveness.” Third, training in these practices can achieve the different mystical aims, experiences, and transformations they seek, all of which relate to the overarching ideal of the unity of Heaven and humanity. These objectives, broadly speaking, include self-understanding, accurately grasping the “principles” of things and affairs, effortless moral virtuosity, “forming one body with all things” (and other types of Confucian mystical union), and exemplifying “sincerity.” Accomplishing them collapses the conventional divide separating several specious dichotomies, such as thought and action, self and other, humankind and nature, internal and external, the subjective and the objective, and moral ought and is. Fourth, the influence that precedent and tradition exert in Confucianism has prompted scholars to devote attention both to notable continuities and to intriguing innovations in comparing ancient mystical ideas, practices, experiences, and aims to later expressions and elaborations of them. At present, much of the scholarship on Confucian mysticism contributes to efforts attempting to provide rich and nuanced analyses of the tradition’s core doctrines, practices, experiences, and ethical and religious aims, by viewing these subjects through the lens of Confucianism’s mystical and spiritual dimensions. Less scholarly attention has been devoted to identifying and explicating the possible contributions that studying Confucian mysticism can make to the scholarship on theories of mysticism and comparative mysticism. Scholars of mysticism have not yet availed themselves of the wealth of data, the possible additional perspectives on contested issues, and the new trajectories for future research that Confucianism offers to these fields. Also, few studies employ the definitions, categories, and theories that have been developed in the contemporary study of mysticism as a methodology for studying Confucian mysticism.

Effects of both the phase and the amplitude inhomogeneities of different dimensionalities on the Greens function and on the one-dimensional density of states of spin waves in the sinusoidal superlattice have been studied. Processes of multiple scattering of waves from inhomogeneities have been taken into account in the self-consistent approximation.

The paper aims to present a reading of the question of Testimony rising in Derrida's later works (from Faith and Knowledge to Poetics and Politics of Witnessing): the experience of Testimony as the irreducible condition of the relation to the Other, of every possible link among living human singularities and, thus, of the thinking of a community to come. This thinking is able to divert the community from the economy grounding and structuring it within our political tradition governed by the metaphysics of presence, which demands the sacrifice of the Other in its multiple theoretical and practical forms. We intend to read this proposal and to point out its rich perspectives by bringing it into the articulation of an ethical-political archi-writing. So we suggest going back to Derrida's early analyses of phenomenology and to De la grammatologie in order to present a reading of archi-writing as the irreducible condition of the relation to otherness and, thus, of the experience through which a living human singularity constitutes itself, a singularity different from the one our tradition compels us to think of within the pattern of the absolute presence to the self, free from the relation to the other.

Abstract. With their donation appeals aid organisations procure a polarised worldview of the self and other into our everyday lives and feed on discourses of “development” and “neediness”. This study investigates how the discourse of “development” is embedded in the subjectivities of “development” professionals. By approaching the topic from a governmentality perspective, the paper illustrates how “development” is (re-)produced through internalised Western values and powerful mechanisms of self-conduct. Meanwhile, this form of self-conduct, which is related to a “good cause”, also gives rise to doubts regarding the work, as well as fragmentations and shifts of identity. On the one hand, the paper outlines various coping strategies used by development professionals to maintain a coherent narrative about the self. On the other hand, it also shows how doubts and fragmentations of identity can generate a critical distance to “development” practice, providing a space for resistant and transformative practice in the sense of Foucauldian counter-conduct.

Dois objetivos nortearam o presente estudo: a) mostrar como os diplomados com um curso superior se sentem influenciados por quatro comportamentos de cidadania (comportamento participativo, orientação prática, conscienciosidade e cortesia) de antigos professores, no que concerne a duas variáveis de impacto (motivação profissional e autoconfiança); b) estudar as concepções desses indivíduos acerca do significado da excelência docente universitária. Foram inquiridos 209 diplomados com curso superior, que foram convidados a descrever os comportamentos de um antigo professor à sua escolha. Os resultados mostram que: a) as quatro categorias comportamentais explicam 79%, 70% e 40% da variância, respectivamente, numa cotação global de desempenho docente atribuída pelos diplomados aos seus antigos professores, na motivação profissional dos mesmos, e na sua autoconfiança; b) os inquiridos consideram que os excelentes professores são os que se orientam fortemente para essas quatro categorias comportamentais. Palavras-chave: cidadania; professores universitários; motivação profissional; autoconfiança; qualidade no ensino superior. Abstract This study aims to show how the citizenship behaviors of university teachers (CBUT) relate with: a) the professional motivation and self-confidence of their students; b) a global performance score given by their students. Four CBUT dimensions were investigated: participatory behavior, practical orientation, conscientiousness and courtesy. A sample of 209 graduates, from several organizations and occupations, was collected. The main results are: a) the four CBUT dimensions explain 79% of the global performance score variance, 70% of the professional motivation variance, and 40% of the self-confidence variance; b) according to the graduates, the excellent teacher is the one who scores well on the four CBUT dimensions. Keywords: citizenship behaviors; university teachers; professional motivation; selfconfidence; quality in higher education.
