Objetivo:Considerando los conceptos de actitud hacia las personas homosexua-les, homofobia y homonegatividad internalizada, este estudio tiene como objetivoscomprobar la hipotética distinción de dos dimensiones dentro del rechazo hacia laspersonas homosexuales, una de rechazo abierto y otra de rechazo sutil.Materialesy métodos:La escala de actitud hacia lesbianas y hombres homosexuales (ATLG),la escala homofobia (HF-8) y la escala de homonegatividad internalizada (HNI-16)fueron aplicadas a una muestra no probabilística de 231 estudiantes mexicanos demedicina y psicología (54% mujeres y 46% hombres). Los datos se analizaron poranálisis factorial confirmatorio.Resultados:Un modelo de dos factores tuvo buenajuste a los datos y su ajuste fue significativamente mejor que el de un modelo deun factor.Conclusiones:La distinción entre manifestaciones sutiles y abiertas en elrechazo hacia personas homosexuales puede ser sostenida empíricamente. Final-mente se hacen sugerencia para la evaluación e intervención en concordancia conesta conceptualización bidimensional. Objective: Taking into account the concepts of attitude toward homosexual persons,homophobia, and internalized homonegativity, the aims of this study were to verify thehypothetical distinction between two dimensions within the rejection toward homosexualpersons, one dimension of open rejection and another dimension of subtle rejection.Materials and methods: The Attitudes Toward Lesbians and Gay men (ATLG) scale,the 8-itemHomophobia (HF-8) scale and the 16-itemInternalized Homonegativity (HNI-16) scale were applied to a non-probability sample of 231 Mexican students of medicineand psychology (54% women and 46% men). Data were analyzed through confirmatoryfactor analysis. Results: A two-factor model had a close fit to the data, and its fitwas significantly better than the fit of a one-factor model. Conclusion: The distinctionbetween subtle and overt manifestations in the rejection toward homosexual personscan be empirically sustained. Finally, suggestions on evaluation and intervention areproposed in accordance with this two-dimensional conceptualization

Abstract Recent developments involving JT gravity in two dimensions indicate that under some conditions, a gravitational path integral is dual to an average over an ensemble of boundary theories, rather than to a specific boundary theory. For an example in one dimension more, one would like to compare a random ensemble of two-dimensional CFT’s to Einstein gravity in three dimensions. But this is difficult. For a simpler problem, here we average over Narain’s family of two-dimensional CFT’s obtained by toroidal compactification. These theories are believed to be the most general ones with their central charges and abelian current algebra symmetries, so averaging over them means picking a random CFT with those properties. The average can be computed using the Siegel-Weil formula of number theory and has some properties suggestive of a bulk dual theory that would be an exotic theory of gravity in three dimensions. The bulk dual theory would be more like U(1)2D Chern-Simons theory than like Einstein gravity.

The adsorption of polyatomics on one- and two-dimensional lattices is studied by combining theoretical modeling, Monte-Carlo (MC), simulations and their correspondence with experimental results. In one dimension, the rigorous statistical thermodynamics of interacting chains has been presented. With respect to two-dimensional adsorption, six different models to study non-interacting adsorbates have been discussed: (i) an extension to two dimensions of the exact thermodynamic functions obtained in one dimension; (ii) the Flory–Huggins's approximation and its modification to address linear adsorbates; (iii) the well-known Guggenheim–DiMarzio approximation; (iv) the fourth one is a new description of adsorption phenomena, based on Haldane's fractional statistics; (v) the so-called Occupation Balance, based on the expansion of the reciprocal of the fugacity; and (vi) a simple semi-empirical model obtained by combining exact one-dimensional calculations and Guggenheim–DiMarzio approach. In addition, the statistical thermodynamics of interacting polyatomics has been developed on a generalization in the spirit of the Bragg–Williams and the quasi-chemical approximations. Comparison with MC simulations and experimental adsorption isotherms are used to test the accuracy and reliability of the proposed models. Finally, applications to heterogeneous systems and multilayer adsorption are discussed.

The objective of this study is to extend the application of the spray-coated tactile sensor, ScoTacS, which is being developed by the authors and can be constructed simply by “coating” with a spray gun, from one dimension to two dimensions, and further to configure it into various shapes such as a ring. This sensor is constructed by coating three layers-conductive, piezoelectric, and resistive films-in sequence. It is based on a unique principle by which the contact position is detected from the delay time, i.e., the time difference between the arrivals of peaks in the output signals. As the delay time varies with the contact position, it can be used to estimate the contact position. In this paper, after analyzing the characteristics of one-dimensional sensors, such as linear and ring sensors, we present the equivalent circuit models and experimental results of a two-dimensional sensor fully coated on a cylinder.

This paper explores the dynamics of attitude change in two dimensions resulting from social interaction. We add a rejection mechanism into the 2D bounded confidence (BC) model proposed by Deffuant et al. (2001). Individuals are characterized by two-dimensional continuous attitudes, each associated with an uncertainty u, supposed constant in this first study. Individuals interact through random pairs. If their attitudes are closer than u on both dimensions, or further than u on both dimensions, or closer than u on one dimension and not further than u + δ u on the other dimension, then the rules of the BC model apply. But if their attitudes are closer than u on one dimension and further than u + δ u on the other dimension, then the individuals are in a dissonant state. They tend to solve this problem by shifting away their close attitudes. The model shows metastable clusters, which maintain themselves through opposite influences of competitor clusters. Our analysis and first experiments support the hypothesis that, for a large range of uncertainty values, the number of clusters grows linearly with the inverse of the uncertainty, whereas this growth is quadratic in the BC model.

Unipolar and bipolar two-dimensional models have been proposed to represent mood. This study showed that a given data set will produce both a unipolar model and a bipolar model when a response-style adjustment is employed. The two models provided mathematically equivalent descriptions of a single-factor space and were equally valid for describing mood differences between successful and unsuccessful military recruits and between recruits in different basic training platoons. Both models discriminated between these groups as well as a six-factor model. The findings confirmed the existence of a reliable two-dimensional representation of self-reported mood but indicated that any choice between unipolar and bipolar models must be based on criteria other than the structure of self-reported mood. Further comparisons to mote complex mood models are needed to determine whether two dimensions adequately represent self-reported mood when a wider range of situational factors and behavioral correlates are considered. If so, a simple, reliable, consensual model for mood would be available to researchers interested in studying mood determinants and effects.

A systematic ħ-expansion of the regulated Witten index Δ(β) in one and two-dimensional SUSY quantum mechanics reveals that the lowest order ħ-term is nonzero, and all terms to at least the next four orders vanish. In one dimension, this lowest order term yields the well-known exact quantum result for an arbitrary superpotential. For the Pauli Hamiltonian with an arbitrary vector potential in two-dimensions, we find the new result that the semiclassical Δ(β) is β-independent and is equal to the number of magnetic flux lines.

The mechanism that locates a shock wave in a transonic flow in one and two dimensions is examined. It is found that in one dimension the shock is located by specifying the downstream pressure whereas in two dimensions the shock is located by the application of an entropy condition at the sonic line.

In decision problems involving two dimensions (like several agents in uncertainty) the properties of expected utility ensure that the result of a two-stepped procedure evaluation does not depend on the order with which the aggregations of local evaluations are performed (e.g., agents first, uncertainty next, or the converse). We say that the aggregations on each dimension commute. In a previous conference paper, Ben Amor, Essghaier and Fargier have shown that this property holds when using pessimistic possibilistic integrals on each dimension, or optimistic ones, while it fails when using a pessimistic possibilistic integral on one dimension and an optimistic one on the other. This paper studies and completely solves this problem when more general Sugeno integrals are used in place of possibilistic integrals, leading to double Sugeno integrals. The results show that there are capacities other than possibility and necessity measures that ensure commutation of Sugeno integrals. Moreover, the relationship between two-dimensional capacities and the commutation property for their projections is investigated.

The present study examined the dimensional structure underlying the Multidimensional Schizotypy Scale (MSS) and its brief version (MSS-B). The MSS and MSS-B were developed to assess current multidimensional conceptualizations of schizotypy. We used Exploratory Graph Analysis (EGA) to evaluate the dimensional structure of the scales in two large, independent samples (n = 6,265 and n = 1,000). We then used Confirmatory Factor Analysis (CFA) to compare the fit of the theoretical dimensions with the EGA dimensions. For the MSS, EGA identified four dimensions: positive schizotypy, two dimensions of negative schizotypy (affective and social anhedonia), and disorganized schizotypy. For the MSS-B, EGA identified three dimensions, which corresponded to the theorized positive, negative, and disorganized dimensions. Based on the MSS’s EGA dimensions, we also estimated a four-factor model for the MSS-B. The CFA comparison found that the four-factor model fit significantly better than the theoretical three-factor model for both the MSS and MSS-B. In short, we propose that the four-factor model supports the theoretical model and offers a more nuanced interpretation of the negative schizotypy dimension. Our findings offer new implications for future research on the MSS and MSS-B dimensions that may provide differential associations with interview and questionnaire measures.

The maximum subarray problem is to find the array portion that maximizes the sum of array elements in it. For K disjoint maximum subarrays, Ruzzo and Tompa gave an O(n) time solution for one-dimension. This solution is, however, difficult to extend to two-dimensions. While a trivial solution of O(Kn3) time is easily obtainable for a two-dimensional array of size n × n, little study has been undertaken to improve the time complexity. We first propose an O(n + K log K) time solution for one-dimension. This is asymptotically equivalent to Ruzzo and Tompa's when sorted order is needed. Based on this, we achieve O(n3 + Kn2 log n) time for two-dimensions. This is cubic time when K ≤ n/ log n. We also show that this upper bound does not exceed O(n3 log n) for K > n, namely O(n3 + min (K,n) · n log n).
