A first order theory T of power λ is called unidimensional if any twoλ+-saturated models of T of the same cardinality are isomorphic. We prove here that such theories are superstable, solving a problem of Shelah. The proof involves an existence theorem and a definability theorem for definable groups in stable theories, and an analysis of their relation to regular types.

We characterize the non-modular models of a unidimensional first-order theory of modules as the elementary submodels of its prime pure-injective model. We show that in case the maximal non-modular submodel of a given model splits off this is true for every such submodel, and we thus obtain a cancellation result for this situation. Although the theories in question always have models whose maximal non-modular submodel do split off, they may as well have others where they don't. We present a (...) corresponding example.

Miller (1956) identified his famous limit of 7 ± 2 items based in part on absolute identification—the ability to identify stimuli that differ on a single physical dimension, such as lines of different length. An important aspect of this limit is its independence from perceptual effects and its application across all stimulus types. Recent research, however, has identified several exceptions. We investigate an explanation for these results that reconciles them with Miller’s work. We find support for the hypothesis that the (...) exceptional stimulus types have more complex psychological representations, which can therefore support better identification. Our investigation uses data sets with thousands of observations for each participant, which allows the application of a new technique for identifying psychological representations: the structural forms algorithm of Kemp and Tenenbaum (2008). This algorithm supports inferences not possible with previous techniques, such as multidimensional scaling. (shrink)

We extend the dichotomy between 1-basedness and supersimplicity proved in Shami :309–332, 2011). The generalization we get is to arbitrary language, with no restrictions on the topology [we do not demand type-definabilty of the open set in the definition of essential 1-basedness from Shami :309–332, 2011)]. We conclude that every hypersimple unidimensional theory that is not s-essentially 1-based by means of the forking topology is supersimple. We also obtain a strong version of the above dichotomy in the case where (...) the language is countable. (shrink)

El influjo de temáticas heideggerianas en la obra tardía de H. Marcuse, todavía implícito en 'Eros y civilización' (1955) ante al peso determinante del psicoanálisis freudiano (1), reaparece de modo explícito en 'El hombre unidimensional' (1964). Ello acontece en dos planos mutuamente interdependientes: el análisis de la reificación en las sociedades unidimensionales de posguerra (2) y la crítica de la racionalidad tecnológica (4). Algunas debilidades conceptuales de ambas obras, derivadas en gran parte de esta recepción de Heidegger, ya fueron (...) subrayadas en su momento por autores pertenecientes a la llamada izquierda husserliana (P. A. Rovatti y P. Piccone, etc.) (3). (shrink)

We prove that any countable simple unidimensional theory T is supersimple, under the additional assumptions that T eliminates hyperimaginaries and that the $D_\phi-ranks$ are finite and definable.

O presente trabalho constrói uma ponte teórica entre Hegel e Marcuse, com intento de demonstrar a possibilidade de transformações históricas concretas, oferecida pela experiência estética. Tendo como paradigma a sociedade administrada, procurou-se estabelecer, a partir de Marcuse e Hegel, um caminho que demonstra como o indivíduo plasma a razão na história, o que pressupõe uma ação libertadora consciente. Todavia, em uma sociedade unidimensional, não há abertura para outras dimensões e, portanto, a razão unidimensional se torna totalitária, paralisando a (...) história. Nesse sentido, buscou-se demonstrar a saída para a dimensão estética, que propicia uma negação da unidimensionalidade da razão moderna. O indivíduo bidimensional, ie, que está aberto para a realidade e para a dimensão estética, pode plasmar a razão na história e, portanto, transformar o mundo. (shrink)

Let A be the category of all reduced compact complex spaces, viewed as a multi-sorted first order structure, in the standard way. Let U be a sub-category of A, which is closed under the taking of products and analytic subsets, and whose morphisms include the projections. Under the assumption that Th(U) is unidimensional, we show that Morley rank is equal to Noetherian dimension, in any elementary extension of U. As a result, we are able to show that Morley degree (...) is definable in Th(U), when Th(U) is unidimensional. (shrink)

A countable unidimensional theory without the omitting types order property (OTOP) has prime models over pairs and is hence classifiable. We show that this is not true for uncountable unidimensional theories.

Razão e liberdade são tidas como os princípios fundadores da sociedade industrial e tecnológica do capitalismo avançado. Para garantir a validação de seu discurso, a tecnologia dispõe de sofisticadas formas de controle, que atuam na consolidação da unidimensionalidade como elemento garantidor da coesão social e da manutenção do status quo. Para isso, o “ordenamento tecnológico” recebe o apoio de uma “coordenação política e intelectual”, que garantem a eficiência processual e a eficácia teleológica das diversas formas de controle da civilização industrial (...) avançada. Este artigo tem como objetivo compreender e expor como para Marcuse, a sociedade do capitalismo afluente, com suas novas formas de controle, protagoniza a formação e consolidação da cultura da unidimensionalidade. Para tanto, a partir do método dialético do filósofo frankfurtiano, debateremos temas como, a contenção do pensamento crítico, condicionamento das necessidades humanas e a racionalidade tecnológica. No intercurso de nossa exposição mostraremos que por trás do discurso da liberdade, a nova sociedade industrial tecnológica, impõe suas formas específicas de controle sobre os indivíduos tendo como resultado a formação de um sistema social unidimensional, onde não há lugar para o pensamento crítico, tido como supérfluo. Pois, não só ameaça a atual compreensão de progresso tecnológico da sociedade unidimensional, como também é capaz de inverter a ordem do discurso estabelecido e desmontar toda e qualquer convivência social do atual status quo.

In a simple theory with elimination of finitary hyperimaginaries if tp(a) is real and analysable over a definable set Q, then there exists a finite sequence ( $a_{i}|i \leq n^{*}$ ) $\subseteq dcl^{eq}$ (a) with $a_{n}*$ = a such that for every $i \leq n*$ , if $p_{i} = tp(a_{i}/{a_{i}|j < i}$ ) then $Aut(p_{i}/Q)$ is type-definable with its action on $p_{i}^{c}$ . A unidimensional simple theory eliminates the quantifier $\exists^{\infty}$ and either interprets (in $C^{eq}$ ) an infinite type-definable (...) group or has the property that ACL(Q) = C for every infinite definable set Q.

Although it is thought that young children focus on the magnitude of the target dimension across ratio sets during binary comparison of ratios, it is unknown whether this is the default approach to ratio reasoning, or if such approach varies across representation formats that naturally afford different opportunities to process the dimensions in each ratio set. In the current study, 132 kindergarteners performed binary comparisons of ratios with discrete and continuous representations. Results from a linear mixed model revealed that children (...) followed an additive strategy to ratio reasoning—i.e., they focused on the magnitude of the target dimension across ratio sets as well as on the absolute magnitude of the ratio set. This approach did not vary substantially across representation formats. Results also showed an association between ratio reasoning and children’s math problem-solving abilities; children with better math abilities performed better on ratio reasoning tasks and processed additional dimensions across ratio sets. Findings are discussed in terms of the processes that underlie ratio reasoning and add to the extant debate on whether true ratio reasoning is observed in young children. (shrink)

O Ensino Médio no Brasil tem enfrentado diversas mudanças sobre seu objetivo principal, sendo fortemente associado ao Exame Nacional do Ensino Médio (ENEM), uma das principais portas de entrada para o Ensino Superior. A redação do ENEM, um dos componentes da prova, segue um formato dissertativo-argumentativo padronizado, exigindo que os candidatos defendam uma opinião sobre temas sociais e proponham uma intervenção, respeitando os direitos humanos. Com base nas teorias de Herbert Marcuse, o artigo discute como a estruturação da redação pode (...) limitar o pensamento crítico dos candidatos, favorecendo uma reprodução de discursos dominantes. Assim, o processo de elaboração da redação, que deveria fomentar o pensamento crítico, acaba se tornando um exercício de conformidade às normas determinadas. A análise da obra de Marcuse, em particular a ideia de "fechamento do discurso", sugere que a redação do ENEM, apesar de sua intenção de avaliar a capacidade de argumentação e escrita dos candidatos, reforça uma padronização discursiva, em que os candidatos são incentivados a seguir fórmulas predefinidas para alcançar uma boa pontuação. Isso leva a refletir que o exame apenas perpetua um discurso unidimensional e operacionalizado. (shrink)

Drawing on the so-called “doctrinal paradox”, List and Pettit (2002) have shown that, given an unrestricted domain condition, there exists no procedure for aggregating individual sets of judgments over multiple interconnected propositions into corresponding collective ones, where the procedure satisfies some minimal conditions similar to the conditions of Arrow’s theorem. I prove that we can avoid the paradox and the associated impossibility result by introducing an appropriate domain restriction: a structure condition, called unidimensional alignment, is shown to open up (...) a possibility result, similar in spirit to Black’s median voter theorem. Specifically, I prove that, given unidimensional alignment, propositionwise majority voting is the unique procedure for aggregating individual sets of judgments into collective ones in accordance with the above mentioned minimal conditions.

Hierarchical complexity's unidimensional measurement can help rectify policy confusion and debates about democratization and terrorism reduction. Stages of political development examined using the method yield task analyses demonstrating why stages cannot be skipped or rushed. Composites of stages and societies' transitions implicate policy change for anti-corruption and nation-building. New indexes for the political domain should be developed using hierarchical complexity to account for and measure a multitude of political tasks regardless of content or context. Measurement offers a reliable, empirical (...) basis to resist attempts to rush development. Hierarchical complexity accounts for why such efforts are doomed in advance to fail. (shrink)

Assume T is unidimensional, 1-based and every minimal type in T is locally finite. If H is an Λ -definable irreducible group, we find an irreducible supergroup G of H in acleq such that any connected subgroup of Gn, n < ω, is the connected component of a subgroup linearly defined over the ring End*. In some cases we can take G = H.

Whether consciousness is unidimensional with states defined along a single scale or it consists of multiple fundamental dimensions has been debated. Clinical assessment of consciousness distinguishes the content of consciousness (awareness) and the level of consciousness (wakefulness or arousal), which conflates firstperson phenomenal properties with third-person observable properties. The state of consciousness is more appropriately defined in terms of subjective level and content which are interdependent. On this account, the state of consciousness is exclusively defined by the experienced mental (...) content, i.e.awareness, whereas behaviour and cognition are overt expressions of the state. Wakefulness and arousal are predisposing factors for specific forms of conscious experience. Nevertheless, a unidimensional representation of consciousness fails to account for the variety of qualitatively different experiences in both normal and altered states of consciousness. To overcome this problem, cognitive and abstract multidimensional models of consciousness have been proposed, but such dimensions are interdependent and lack axiomatic support. A novel multidimensional characterization of consciousness based on the brain's macroscale functional geometry provides an alternative, empirically grounded model whose dimensions are defined by neurofunctional rather than behavioural attributes. The state of consciousness is then represented as a point in this functional multidimensional space. (shrink)

This article challenges the unidimensional view of abusive supervisors and examines how employees respond to abuse when the transgressing boss also has a positive impact on others. Drawing on deonance and fairness theory, we propose competing hypotheses about the influence of prosocial impact. Specifically, we use deonance theory to suggest that prosocial impact might buffer the effects of abusive supervision. Alternatively, we incorporate fairness theory to predict that prosocial impact strengthens injustice perceptions and thereby worsens consequences of abuse. Two (...) field studies show support for fairness theory, demonstrating that employees perceive greater injustice, and show stronger retaliatory behaviors, when the abusive supervisor makes a positive difference in the workplace. A final field study replicates these results, while also testing the underlying cognitive process employees use to assess the interplay between “good” and “bad” supervisory characteristics. This article contributes insights to abusive supervision, prosocial impact, organizational justice, and behavioral ethics literatures. (shrink)

Abstract:This paper investigates whether, in theoretical terms, corporations can be citizens. The argument is based on the observation that the debate on “corporate citizenship” (CC) has only paid limited attention to the actual notion of citizenship. Where it has been discussed, authors have either largely left the concept of CC unquestioned, or applied rather unidimensional and decontextualized notions of citizenship to the corporate sphere. The paper opens with a critical discussion of a major contribution to the CC literature, the (...) work of Logsdon and Wood (Wood and Logsdon 2001; Logsdon and Wood 2002). It continues with a consideration of the nature and role of metaphors for business and of the contestable nature of the political concept of citizenship. It evaluates corporations as citizens through a four-dimensional framework of democratic citizenship offered by Stokes (2002). The analysis suggests that corporations do not easily fit the “liberal minimalist” model of citizenship. It finds, however some possibilities for fit with the three more participatory models. The paper concludes by cautioning against basing corporate citizenship on legal and administrative status or identity, and mapping out specific criteria by which we might determine whether corporations could be considered as citizens by virtue of their participation in processes of governance.

A multidimensional measure of ethical culture was examined for its relationship to person–organization fit, ethical intent and organizational citizenship behavior, using a sample of 525 employees from the financial industry in Spain. As hypothesized, relative to studies using unidimensional assessments, our measure of EC was more strongly related to ethical intent and organizational citizenship. Also, significant differences were found in the degree to which each the EC dimensions related to both ethical intent and OCB. Finally, in a first for (...) the literature, we demonstrated the important role of overall P–O fit in connection with EC, ethical intent, and organizational citizenship. Specifically, as hypothesized, P–O fit moderated positively the association between EC and ethical intent, but mediated the EC–OCB relationship. (shrink)
