Robust regression: Testing global hypotheses about the slopes when there is multicollinearity or heteroscedasticity

A well-known concern regarding the usual linear regression model is multicollinearity. As the strength of the association among the independent variables increases, the squared standard error of regression estimators tends to increase, which can seriously impact power. This paper examines heteroscedastic methods for dealing with this issue when testing the hypothesis that all of the slope parameters are equal to zero via a robust ridge estimator that guards against outliers among the dependent variable. Included are results related to leverage points, meaning outliers among the independent variables. In various situations, the proposed method increases power substantially.     

Support of Theological Education in a Cross‐cultural Setting

Based on recent reports on the global status quo of theological education, including a mapping of Danish organizations supporting theological education in a cross‐cultural setting, the paper asks how theological education is best supported. It argues that theological education, while referring to a historical heritage and sacred text, is also exposed to developments in church and society. Stretched between the historical and contemporary perspective, theological education includes a cultural component that we need to consider when discussing development and support. The paper argues further that support of theological education offered in a cross‐cultural setting is susceptible to failure if the cultural aspect is not considered, primarily through engaging in the cultural background of the supporting agencies. As a help to identifying the cultural element, the paper proposes four indicators, challenging agencies of the global North to face latent aspects of culture and secularization, presenting a global and social perspective of theological education. The cultural component visualized in cross‐cultural support reveals that we must complement the classical notion of theological education as Christian leadership training with an understanding of formation, where spiritual and cognitive aspects accompany social and cultural critique of totalitarian regimes both inside and outside churches. Critique in this setting is not a matter of giving in to secularization, but rather expresses an openness to historical and contemporary perspectives and a commitment to the sources of faith.     

Promoting intergroup openness and support for equality in a new cultural context: Replicating the effects of internal criticism

Exposure to an outgroup member voicing criticism of his or her own group fosters greater openness to the outgroup’s perspective. Research suggests that this effect owes its influence to a serial process in which participants’ perception of the risk involved in voicing internal criticism leads to an increase in the perceived credibility of the speaker. The credibility makes it possible for the speaker to be viewed as open-minded, which subsequently inspires greater hope. This process culminates in an increased openness to the outgroup. These findings have been restricted to the Israeli-Palestinian conflict, but here we examine their generalizability to racial conflict in the United States. Results reveal that White Americans exposed to internal criticism expressed by a Black authority figure express greater openness to African-American perspectives on race relations and are more willing to support policies of racial equality. Replicating past research, this effect is serially mediated by risk, credibility, and hope.     

National identification and support for discriminatory policies: The mediating role of beliefs about laïcité in France

In France, laïcité is a legal principle enforcing State secularism. However, research indicates that Modern (vs. traditional) beliefs about laïcité (ML) help legitimate prejudice against minorities. From Social Identity Theory, we hypothesized that ML should be positively linked with national identification, stereotyping, prejudice and support for discrimination. Accordingly, we demonstrate that ML independently predicts support for discriminatory policies (Study 1a, N = 241) and Maghrebi IAT scores (Study 1b, N = 242). ML mediates the link between national identification and Generalized Prejudice (Study 2a, N = 215; Study 2d, N = 114) as well as Support for Discriminatory Policies (Study 2b, N = 250). Experimental corroboration of this mediation was provided (Study 2c, N = 100). An exploratory study showed that priming ML led to more support for discrimination through national identification (Study 3, N = 89). These results reveal the important intergroup regulation feature of ML beliefs in France.     

Rethinking Affective Experience and Popular Emotion: World War I and the Construction of Group Emotion in International Relations

Research in International Relations (IR) frequently confronts claims about the emotions shared by members of a group. While much attention has been devoted to the potential for affective and emotional experience beyond the individual level, IR scholars have said less about the politics of invoking popular emotion. This article addresses that gap. Specifically, we argue that between individual—and even shared—affective experience on the one hand and group‐based “popular emotion” on the other exists not mechanisms of aggregation but rather processes of framing, projection, and propagation that are deeply political. We distinguish between two tropes that commonly structure references to popular emotion: communal emotion, the idealized attribution of an authentic, unifying emotional response of “the people,” and mass emotion, a volatile and potentially dangerous mob‐like reaction, but one also susceptible to manipulation. Using the outbreak of World War I as a showcase, we demonstrate the political significance of popular emotion, including its enduring relevance for understanding contemporary populism.     

Oscillatory gamma activity mediates the pathway from socioeconomic status to language acquisition in infancy

BackgroundThe predictable path to child language acquisition is largely constrained by both brain maturation and environmental experience. The synchronized activity of large numbers of neurons gives rise to macroscopic brain oscillations on an electroencephalogram (EEG). It has been found that neural oscillations at rest in the gamma frequency band (25–45 Hz) are associated with development of different cognitive systems, including language. Although the etiology of language is explained by genetically driven brain maturation factors, environment plays a significant role. Specifically, candidate pathways from environment to language development include sociodemographic factors, primarily socioeconomic status (SES) which is likely to exert its effects on language development through other factors, such as parenting style.Despite these assumptions, no studies have so far examined the interrelation between brain maturation factors such as gamma frequency oscillatory activity, environmental factors such as SES, and language acquisition.Aim and methodIn a longitudinal study of 84 Italian typically developing infants, we measured the power of oscillatory gamma activity as mediator between SES and language acquisition. Baseline EEG and information about SES were collected when infants were aged 6 months. Children were followed-up longitudinally to measure expressive vocabulary and Mean Length of Utterance (MLU) at 24 months.ResultsThe mediation model showed that SES is associated with gamma power which, in turn, is associated with expressive language at age 24 months. A higher SES predicted an increase in left central gamma power which, in turn, predicted better language scores.ConclusionsThese results confirm the predictive role of gamma activity oscillatory activity on later language acquisition, suggesting a specific role for these oscillatory mechanisms in language development milestones such as vocabulary development and early word combination. Furthermore, they suggest that SES differences in brain activity may be apparent at early stages of life and affect later language skills. If replicated, our findings could contribute to identifying highest-risk children and may prompt cost-effective preventive/treatment strategies.     

Trace of pace,place, and space in personal relationships: The chronogeometrics of studying relationships at scale

The study of personal relationships has traditionally relied on self‐reports or observations of face‐to‐face interaction. Digital media increasingly provide the ability to trace communication and relationships at scale. Such methods portend significant theoretical and methodological challenges, as well as potential. As a way of illustrating such potential, big data approaches to the select traditional relational concepts of routine relating, propinquity, homophily, small world, and reciprocity are reviewed. The fields of communication and personal relationships will need to inform such research by developing their own interdisciplinary relationships with geographic information sciences, computational linguistics, and computer sciences or cede a significant frontier of their field to these other disciplines.     

Promoting positive community relations: what can RE learn from social psychology and the shared space project?

In this article we considered the relevance of specific claims that ‘multi-faith’ approaches to Religious Education (RE) play a role in promoting good community relations. In doing so, we adopted a social-psychological perspective where engaging in positive and meaningful interactions with diverse others reduces prejudice. Survey responses from 92 RE teachers across the UK were examined to determine the extent to which strategies for promoting positive community relations were embedded within classroom practice. We next examined whether teachers intuitively used social psychological theory – namely the contact hypothesis – to promote positive communities in their classrooms. Results demonstrated that the majority of surveyed RE practitioners perceived community relations to be a core aim of RE and that contact theory was applicable to their practice. Teachers reported examples of how they embed both contact theory and RE in their classrooms but not all of these aligned with social psychological theory. Findings suggest that successful practice in RE may be further developed by integrating theoretical principles of the contact hypothesis. Implications and future directions will be discussed.     

The structure of trust as a reflection of culture and institutional power structure: Evidence from four East Asian societies

Using the Global Trust Inventory, an integrated measure of trust toward 21 relationships and institutions, the structure of trust was explored in four East Asian societies (Mainland China, Japan, South Korea, and Taiwan). The Western model, in which trust is distributed among seven factors representing different branches of society, did not generalize to these East Asian societies, perhaps due to differences in culture and institutional power structures. Instead, two unique structures of trust were identified. Mainland China had a top‐down structure of trust (the China model), in which trust is hierarchically separated between the central government and subordinate implementing bodies. The other three democratic East Asian societies shared a hybrid structure of trust (the Democratic East Asian model) that has a degree of similarity to both the China model and the Western model. Having established two similar, but still distinct models, a cross‐cultural comparison was made on the proportions of trust profiles generated by latent profile analysis. Mainland China had the largest proportion of people with a high propensity to trust, followed by Japan and South Korea, and Taiwan was the least trusting. Implications of the structure of trust and this alternative approach to conducting cross‐cultural comparisons are discussed.
