Ministering at the Margins in a Time of Pandemic

COVID-19 is having a devastating effect globally, especially among those who live at the margins of societies. Health and economic crises are impacting communities and countries, with particularly adverse effects on vulnerable populations. COVID-19’s impact is increased when we factor in racism, land displacement, and gender injustice. The marginalization and oppression experienced from racial injustice, displacement, and gender injustice increase vulnerability and intensify trauma from COVID-19 globally. Churches can respond effectively to the COVID-19 pandemic with particular focus on communities at the margins. Churches that respond to COVID-19 through ministries of evangelism, compassion, empowerment, and advocacy can demonstrate Christ’s love in the midst of the pandemic and contribute to reconciliation and solidarity with vulnerable communities forced to the margins. This article offers insights related to four themes identified by the reference group for the Pilgrimage of Justice and Peace that was initiated at the 10th Assembly of the World Council of Churches in Busan in 2013.     

The Integrated Acculturation Model: Expanding Acculturation to Cultural Identities in Addition to Race and Ethnicity

This article is an attempt to integrate existing conceptual knowledge on acculturation as well as to expand the use of the construct, which has traditionally had race and ethnicity as its focus, to also include cultural identities such as sexual orientation, gender identity, nationality, and disability. The article begins with a review of existing theoretical contributions from both the United States and Europe. We then propose a model to update and expand the use of acculturation. Finally, we provide an assessment framework. Este artículo es un intento de integrar los conocimientos conceptuales existentes sobre la aculturación además de expandir el uso de este constructo, que tradicionalmente se ha enfocado hacia la raza y la etnicidad, para incluir también identidades culturales tales como la orientación sexual, la identidad de sexo, la nacionalidad y la discapacidad. El artículo comienza con una revisión de las contribuciones teóricas existentes tanto de Estados Unidos como de Europa. A continuación, proponemos un modelo para actualizar y expandir el uso de la aculturación. Por último, proporcionamos un marco de evaluación.     

Holographic string encoding

In this article, we apply a special case of holographic representations to letter position coding. We translate different well-known schemes into this format, which uses distributed representations and supports constituent structure. We show that in addition to these brain-like characteristics, performances on a standard benchmark of behavioral effects are improved in the holographic format relative to the standard localist one. This notably occurs because of emerging properties in holographic codes, like transposition and edge effects, for which we give formal demonstrations. Finally, we outline the limits of the approach as well as its possible future extensions.     

On the adequacy of current empirical evaluations of formal models of categorization

Categorization is one of the fundamental building blocks of cognition, and the study of categorization is notable for the extent to which formal modeling has been a central and influential component of research. However, the field has seen a proliferation of noncomplementary models with little consensus on the relative adequacy of these accounts. Progress in assessing the relative adequacy of formal categorization models has, to date, been limited because (a) formal model comparisons are narrow in the number of models and phenomena considered and (b) models do not often clearly define their explanatory scope. Progress is further hampered by the practice of fitting models with arbitrarily variable parameters to each data set independently. Reviewing examples of good practice in the literature, we conclude that model comparisons are most fruitful when relative adequacy is assessed by comparing well-defined models on the basis of the number and proportion of irreversible, ordinal, penetrable successes (principles of minimal flexibility, breadth, good-enough precision, maximal simplicity, and psychological focus).     

Impact of high-performance work systems on individual- and branch-level performance: test of a multilevel model of intermediate linkages

We proposed and tested a multilevel model, underpinned by empowerment theory, that examines the processes linking high-performance work systems (HPWS) and performance outcomes at the individual and organizational levels of analyses. Data were obtained from 37 branches of 2 banking institutions in Ghana. Results of hierarchical regression analysis revealed that branch-level HPWS relates to empowerment climate. Additionally, results of hierarchical linear modeling that examined the hypothesized cross-level relationships revealed 3 salient findings. First, experienced HPWS and empowerment climate partially mediate the influence of branch-level HPWS on psychological empowerment. Second, psychological empowerment partially mediates the influence of empowerment climate and experienced HPWS on service performance. Third, service orientation moderates the psychological empowerment-service performance relationship such that the relationship is stronger for those high rather than low in service orientation. Last, ordinary least squares regression results revealed that branch-level HPWS influences branch-level market performance through cross-level and individual-level influences on service performance that emerges at the branch level as aggregated service performance.     

Exemplar similarity and rule application

We report four experiments examining effects of instance similarity on the application of simple explicit rules. We found effects of similarity to illustrative exemplars in error patterns and reaction times. These effects arose even though participants were given perfectly predictive rules, the similarity manipulation depended entirely on rule-irrelevant features, and attention to exemplar similarity was detrimental to task performance. Comparison of results across studies suggests that the effects are mandatory, non-strategic and not subject to conscious control, and as a result, should be pervasive throughout categorization.     

Interaction in the psychoanalytic situation

In psychoanalytic psychotherapy we are primarily interested in psychic change and how to facilitate it for the better. Change is a universal property of matter, living or inanimate: everything in nature is influenced by everything else; interaction is ubiquitous. In the early years of psychoanalysis, the prevailing view was that therapeusis was essentially informational—insight and awareness would bring about changes in the ways one would experience events and respond to them. Over time, there has been a subtle shift from the informational perspective to the transformational, where insight is often retrospective rather than the active agent. The growing awareness of the need to be deeply recognized and responded to by another human being is reflective of this shift and has loomed ever larger in the interactive arena known as psychoanalysis. This paper focuses on a single facet of the need for recognition by another—the role of enacted response in effecting psychic change. It also addresses another level of the meaning of interaction: Whereas the internal interaction between perception and response has tended to be looked upon, in psychoanalysis, as unidirectional, the present discussion draws attention to the complexity of the bidirectional interaction between perception and response.     

Feast your eyes: hunger and trait reward drive predict attentional bias for food cues

Appraisal theories of emotion predict that the relevance of a stimulus to a person's needs and goals influences attentional allocation. We used a modified visual probe task to examine the influence of hunger and trait reward drive on food-related attentional bias. Both hunger and trait reward drive predicted degree of attentional "disengagement" from food images at short (100 ms), but not long (500, 2,000 ms) stimulus durations. Effects of hunger were found for both bland and appetizing foods, while effects of reward drive were restricted to appetizing foods. Our findings extend previous research showing delayed "disengagement" from threat-related stimuli, suggesting that both organismic- and goal-relevance are key biasing factors in attentional competition.     

Identifying lesions on structural brain images--validation of the method and application to neuropsychological patients

The study of neuropsychological disorders has been greatly facilitated by the localization of brain lesions on MRI scans. Current popular approaches for the assessment of MRI brain scans mostly depend on the successful segmentation of the brain into grey and white matter. These methods cannot be used effectively with large lesions because lesions usually impair segmentation. We propose a novel, fully automated approach for the delineation of brain lesions on MR scans. This method involves comparing a skull stripped, smoothed, unsegmented T1 images to a control group using the general linear model. We tested this method by using images with simulated lesions of different sizes and images containing real lesions from patients with language deficits. We also tested how varying the size of the Gaussian smoothing kernel affects detection. The simulation was informed by findings of a lesion morphological study also presented here. The proposed method detected simulated lesions effectively in the range of 30--90%相似文献
