Two measures of effect size are described for the Mantel-Haenszel test. Both measures belong to the r-family of effect size measures. One measure is based on a maximum-corrected model, and the second measure is based on a chance-corrected model. 相似文献

Our purpose in the following was to investigate the start-up rhetoric employed by U.S. President Barack Obama in his speeches.
The initial 5 min from eight of his speeches from May to September of 2009 were selected for their variety of setting, audience,
theme, and purpose. It was generally hypothesized that Barack Obama, widely recognized for the excellence of his rhetorical
performance, would pursue both constant and variable strategies in his effort to establish contact with his audience. More
specifically, it was hypothesized that the make-up of the audience—primarily native or non-native speakers of English—would
be a prominent independent variable. A number of temporal and verbal measures were used as dependent variables. Variations
were evident in mean length in syllables and duration in seconds of utterances (articulatory phrases), articulation rate in
syllables per second of ontime, mean duration of silent pauses in seconds, and frequency of fillers, hesitations, colloquial
words and phrases, introductory phrases, and 1st person singular pronominals. Results indicated that formality versus informality
of the setting and presence or absence of a teleprompter were more prominent than native versus non-native audiences. Our
analyses confirm Obama’s skillfulness in challenging and variable settings and clearly detect orderliness and scientific generalizability
in language use. The concept of orality/literacy provides a theoretical background and emphasizes dialogical interaction of
audience and speaker. 相似文献

This paper introduces the special section by presenting a historical and conceptual review of theory and research on the psychology of men and masculinity and then introducing the section’s papers. Men have power because of their gender, but differ in access to power based on other individual characteristics such as social class, income, education, ethnicity, sexual orientation, or physical strength. Men typically have been studied as generic rather than gendered beings in psychology. In contrast, a gendered analysis of men highlights the ways in which men’s experience, masculinity, and behavior contribute to health and social problems and to resources commonly addressed by community psychologists. Our gendered analysis suggests ways of working with men in group, organizational, and community settings to create positive individual and social change. Crucial to this analysis is the paradox that enacting masculinity both privileges and damages men. A second paradox stems from men having power as a group over women while individual men feel powerless or victimized by women as a group. The papers in this volume illustrate key themes of our historical and conceptual review through studies of adolescent and adult men as fathers, patients, partner abusers, support group participants and community members, and through examination of the impact of their gendered identities and behavior on health, well being, and justice. 相似文献

An alternative models framework was used to test three confirmatory factor analytic models for the Short Leyton Obsessional
Inventory-Children’s Version (Short LOI-CV) in a general population sample of 517 young adolescent twins (11–16 years). A
one-factor model as implicit in current classification systems of Obsessive–Compulsive Disorder (OCD), a two-factor obsessions
and compulsions model, and a multidimensional model corresponding to the three proposed subscales of the Short LOI-CV (labelled
Obsessions/Incompleteness, Numbers/Luck and Cleanliness) were considered. The three-factor model was the only model to provide
an adequate explanation of the data. Twin analyses suggested significant quantitative sex differences in heritability for
both the Obsessions/Incompleteness and Numbers/Luck dimensions with these being significantly heritable in males only (heritability
of 60% and 65% respectively). The correlation between the additive genetic effects for these two dimensions in males was 0.95
suggesting they largely share the same genetic risk factors. 相似文献

The metallic glass Pd40Cu30Ni10P20 in as-cast or pre-annealed states was shot-peened successively at room temperature or at 77 K. The structural state of the glass was characterized by the relaxation spectrum measured in a differential scanning calorimeter. Mechanically induced relaxation of the as-cast glass and mechanically induced rejuvenation of pre-annealed samples are both more evident at 77 K than at 298 K, enabling deductions about the underlying mechanisms. The relaxation spectrum of the glass as a function of temperature displays two broad maxima, which occurring at the higher temperature is attributed to the part of the free-volume distribution associated with flow defects. In samples shot-peened at 77 K, the stored energy after deformation can be as high as 20% of the cold work. Shot-peening simultaneously generates flow defects within shear bands and destroys them in the matrix between bands: whose effect dominates is principally dependent on the initial state of relaxation of the glass. Shot-peening of partially crystallized samples appears capable of breaking up and dispersing crystallites without inducing any further significant crystallization. 相似文献

Introduction A great volume of popular literature produced by Islamists strives to demonstrate the universal validity of the Islamic political principles and their applicability in any time and place. Although there is an agreement on certain characteristics of a government in a Muslim society, the debate reflects quite varied interpretations and some essential theoretical differences. The controversy stems largely from the conditions that scholars live in. Regarding the revived interest in creating a state based on Islamic political and moral guidelines, it is possible to encounter various interpretations and different standpoints. For instance, one point of view asserts that ‘the undemocratic nature of Islamic political ideology, popularised in the present times by fundamentalist ideologues, commends it to regimes which have no popular support and need to find some measure of legitimacy’ (Tibi, 1998). With the failure of man-made ideologies and withdrawal of imperialist western powers, according to another standpoint, the inhabitants of the Third World countries were led to revitalise their own sociopolitical values and institute their own political systems. In the case of the Islamic world, the idea of a state based on Islamic political principles, envisaged in the latter perspective, is ’the rekindling of the typical Islamic political ethos‘; in that Islam unifies the spiritual and social realms, it is therefore impossible to divorce politics from religion (Sulaiman, 1987). There is a wide range of contributions and critiques on the issue of Islamic principles guiding the constitutional aspects of a state, particularly since the Iranian Revolution in 1979. The interest in this matter has increased since the terrorist attacks in the USA on 11 September 2001, coinciding with a rising interest in such issues as Islamic social order and so-called Islamic terrorism. Nevertheless, most of these writings are popular and sensational; analytical studies are few. This article aims to fill the gap in scholarly inquiry into such an important matter by exploring the political ideas of major contemporary Muslim thinkers, and by identifying some essential characteristics for a state based on Islamic political principles in the light of the views of these scholars. 相似文献

We assessed the role of parental behaviors on sport performance anxiety. Measures of trait anxiety, parental pressure, and parent-initiated motivational climate were administered to youth swimmers throughout the season. High parental pressure within either a low mastery or a high ego motivational climate was associated with the highest levels of anxiety at all time points. An early-season, high-pressure/low-mastery combination was also associated with relative increases in anxiety over the season, whereas high pressure within a high mastery climate was associated with relative decreases. Results indicate that parental pressure can have differential effects depending upon motivational climate. 相似文献

Though empathy remains a central concept in psychoanalysis, attempts to explain the operations and functions in the empathic process have been as divergent as the various meanings associated with the term itself. Any explanation of the mechanism of empathy must include how we have access to the inner experience of others or account for the link between the empathizer and the inner state of the object. In this paper, the authors review different models (Freud, 1921; Kohut, 1959; Basch, 1983, 1988; Buie, 1981; Schafer, 1968; Klein, 1946, 1963) of empathic understanding and note that while these models rely on imitation, identification, merger, projection, or inference as the basis of empathic understanding, each implies only an indirect understanding of the states of others. The authors propose a two‐phase model of empathy that differs from those models reviewed in that their position assumes that the perception of emotion in the other is immediately accessible through isomorphic psychological and physical processes that often result in an experience of resonance of the same emotion inthe self (Beebe, 1990). According to this view, the empathic process consists of an initial perceptual phase that generates affective resonance and a second phase in which complex cognitive‐affective operations contribute to the construction of meaning. We posit that empathic understanding affords the observer direct access to certain qualities of the other's experience. The model borrows from Wolfgang Köhler's (1947) concept of isomorphism and Rudolph Arnheim's (1949) theory of the perception of expression. Evidence for this model is presented from experimental psychology. A discussion of a case from an earlier paper on empathy by Beres and Arlow (1974) illustrates how the operations underlying empathy contribute to understanding a patient in a clinical setting. Finally, we conclude the paper with a brief discussion of some of the clinical implications of this model. 相似文献
