Fisher transformation based confidence intervals of correlations in fixed- and random-effects meta-analysis

Meta-analyses of correlation coefficients are an important technique to integrate results from many cross-sectional and longitudinal research designs. Uncertainty in pooled estimates is typically assessed with the help of confidence intervals, which can double as hypothesis tests for two-sided hypotheses about the underlying correlation. A standard approach to construct confidence intervals for the main effect is the Hedges-Olkin-Vevea Fisher-z (HOVz) approach, which is based on the Fisher-z transformation. Results from previous studies (Field, 2005, Psychol. Meth., 10, 444; Hafdahl and Williams, 2009, Psychol. Meth., 14, 24), however, indicate that in random-effects models the performance of the HOVz confidence interval can be unsatisfactory. To this end, we propose improvements of the HOVz approach, which are based on enhanced variance estimators for the main effect estimate. In order to study the coverage of the new confidence intervals in both fixed- and random-effects meta-analysis models, we perform an extensive simulation study, comparing them to established approaches. Data were generated via a truncated normal and beta distribution model. The results show that our newly proposed confidence intervals based on a Knapp-Hartung-type variance estimator or robust heteroscedasticity consistent sandwich estimators in combination with the integral z-to-r transformation (Hafdahl, 2009, Br. J. Math. Stat. Psychol., 62, 233) provide more accurate coverage than existing approaches in most scenarios, especially in the more appropriate beta distribution simulation model.     

The Transformative Effects of Stigma: Coping Strategies as Meaning‐Making Efforts for Immigrants Living in Greece

The present article examines the strategies that immigrants living in Greece use to cope with stigma that arises in their interaction with both Greek society and their communities of origin. Drawing on interviews and focus groups conducted with immigrants from a variety of countries, a dialogical analysis illuminates the ways in which immigrants actively negotiate stigmatizing perspectives and transform themselves. Strategies include the deployment of social categories such as those of ‘human being’ and ‘crazy’ person, and concepts such as those of ‘lawfulness’ and ‘fate’. These were used to construct meanings of equality and inclusion into society, to deny responsibility for stigma and to discredit stigma as absurd. They enabled participants to see themselves as proud, equal, self‐dependent individuals who plan actions for social change. The article suggests that coping with stigma should not only be understood in terms of stress regulation, leading to positive or negative outcomes, as suggested by current literature, but as a meaning‐making effort, through which individuals transform the way they see themselves and act within their world. A meaning‐making approach moves away from individualistic, outcome‐oriented explanations to a socially situated perspective on stigma that studies the processes through which social meanings are subjectively perceived as stigmatizing and are used to challenge stigma.

Working Experientially and Somatically with Couples

SUMMARY

Working experientially and somatically with couples is a powerful method of accessing, exploring, and transforming both intra-psychic issues and interactional patterns. In this article, a number of methods of working experientially will be described, along with their underlying rationale. Basic assumptions about the nature of couple's difficulties and the role of the therapist also will be explored along with an integrated approach to assessment that provides a solid basis for these dramatic interventions.     

Relational dynamics of charismatic organization: The complementarity of love and power

Abstract: This paper outlines a new theory of structural transformation in charismatic systems by postulating a complementary relationship between love and power. Radical reorganization of social organization, the function of charismatic systems, requires mobilizing and realigning enormous amounts of social energy. The source of this social energy is love. When patterned as communion, love fuses the group into an undifferentiated whole and releases the social energy previously locked up as institutionalized structure.

Released from structure or form, however, social energy is highly volatile and produces immense pressures towards instability. Counterbalancing the pressure from communion, a strong, collective order of power functions to harness and align the energy, thereby promoting group stability and enhancing the prospects for structural transformation. Data from a national study of sixty urban communal organizations are used to ground key aspects of the theory.     

Synergic inquiry and evolution of consciousness

Challenged by overwhelming social and ecological problems and crises, a new alternative that re‐explains the world is called for to transform human consciousness. The author argues that an alternative should meet the following criteria: (1) corresponding to the total reality, (2) contributing evolution of consciousness, and (3) coming with an adequate action methodology. Based on an understanding of the coherent patterns—the processes of differentiation and integration—through which the universe evolves, the Synergy Principle of the universe is established. Dimensionality of consciousness—the visible, logical, and mythical—is also presented. Further, the Synergic Inquiry methodology designed to guide human action work for consciousness transformation at various levels of human systems is developed. Finally a few levels of synergy are also discussed.     

The Akashic Field and Archetypal Occupations: Transforming Human Potential Through Doing and Being

The global crisis is heralding change within collective consciousness and humanity will be challenged to transform behaviors to co-create a sustainable future. Ervin Laszlo's Akashic Field could inspire such an archetypal shift, as exemplified in C.G. Jung's individuation process. Jung's encounters with the archetypes from the collective unconscious led him to connect deeply with Akashic experiences, which resulted in him expressing his human potential through renewed ways of doing and being. Humanity has an opportunity to develop and integrate transpersonal consciousness through engaging archetypal and Akashic experiences, which could inspire collective action for the co-creation of an improved future.     

Technology,gender, and history: Toward a nonlinear model of social evolution

This paper presents a new nonlinear cognitive map of social evolution— sharply departing from the conventional 19th century‐based theories of linear stages from barbarism to civilization. It draws from a data base that includes the whole of humanity (both its female and male halves). And it takes into account new data from archaeology indicating that civilization is not only thousands of years older than previously thought, but originally oriented more closely to what the author calls a Partnership rather than a Dominator model of social organization. Covering over 25,000 years of social history, this article charts major technological phase changes—from the agricultural revolution circa 10,000 years ago to the industrial and more recently electronic revolutions or modern times—from the perspective of the tension between the Dominator and Partnership models. Most critically, it shows how the present period of social disequilibrium leads us to either an evolutionary breakdown or breakthrough, with the determining factor not technology per se, but rather how effectively and quickly we shift to a social organization orienting primarily to partnership rather than domination.     

Electron spin resonance of hydrogenated amorphous silicon-carbon alloy films prepared by magnetron sputtering

Abstract

New electron spin resonance (ESR) lines with g¹ = 2·0017 and g₂ and g₃ = 2·0006 have been found in the ESR spectra of as-deposited a-Si_1–x C_x:H films prepared by magnetron sputtering of silicon in the gas mixtures of methane and argon. Similarities between the observed spectra and those for the E′ centre in glassy SiO₂ are discussed.     

Shape deformation by moving a glissile interface with one set of misfit dislocations

Transformation and misfit dislocations are used to describe the motion of glissile interfaces with one set of misfit dislocations in the framework of the Frank?Bilby equation. The sweep of these glissile interfaces brings about an invariant-plane-strain type shape deformation. Our approach explains the glissile motion of martensitic interfaces and small-angle symmetrical tilt grain boundaries. It is consistent with the phenomenological theory of martensite crystallography but more flexible.
