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.     

Displacement as trauma and trauma as displacement in the experience of refugees

This paper investigates the relations between displacement, home, trauma and the self in the experience of refugees, which has become an issue of unexpected and far-reaching proportions in recent times. It questions to what extent and under what conditions displacement in the world may be traumatic and how trauma may be considered the effect of an inner displacement. Refugees’ lives are marked by forced migration that is related to a certain suffering due to the changes in their family, relational, social and cultural lives. The paper explores the extent to which these changes can represent a break so significant as to be traumatic. It outlines the way in which traumatic experiences can produce an inner displacement and reorganization of one’s mental life that leads to a focus on traumatic complexes. Under the most severe traumatic conditions, this can be understood as a displacement of the central axis of Self, in which the ego complex yields its position to other complexes, with a deep change in the organization and functioning of self. The experience of refugees highlights the way in which we live in a matrix of conscious and unconscious links between inner and outer worlds that need deeper and simultaneous consideration to understand their implications and mutual resonances for the psyche. Clinical cases of refugees will illustrate some aspects of these interconnections.     

A comparison of displacement and reinforcer potency for typically developing children

Previous researchers found that individuals with intellectual and developmental disabilities tend to prefer edible over leisure stimuli, although leisure stimuli may still function as reinforcers. We replicated and extended previous research in a 2-part experiment with typically developing children. In Experiment 1, we evaluated 15 children's preference for leisure and edible stimuli. Five of 15 participants preferred edible over leisure stimuli, 3 of 15 participants preferred leisure over edible stimuli, and the remaining 7 of 15 participants did not show a preference for a stimulus class. In Experiment 2, we compared the reinforcer potency of the top-ranked stimulus from each class with 7 of the 8 participants who showed displacement of one stimulus class. Four of 7 participants allocated more responding to the task associated with the top-ranked stimulus and 3 of 7 participants showed no differences in responding to the task regardless of the stimulus rank.     

Family therapists as front line mental health providers in war-affected regions: using reflecting teams, scaling questions, and family members in a hospital in Central Africa

This paper will illustrate the utilization of systemic family therapy services inside a hospital in a war-affected region of the Central African Republic. Through an international non-governmental organization (NGO), the author, a family therapist, provided counselling supervision and services to hospital staff and patients in an area of open conflict in the northern region of the country. In circumstances of chronic insecurity fuelled by both government and rebel forces, families displaced in this region are vulnerable to numerous health conditions and social problems. Family therapy techniques and ideas were used to work with individuals, couples and families presenting with health and social problems resulting from HIV-TB, infections, chronic malnutrition, acute poisoning and beliefs about sorcery. Case examples illustrate the systems consultation model used with the mental health team in order to expand and promote the sustainability of patient mental healthcare in this underserved region.     

Auditory stimulation affects apparent motion1

Abstract: In two experiments, we investigated how the number of auditory stimuli affected the apparent motion induced by visual stimuli. The multiple visual stimuli that induced the apparent motion on the front parallel plane, or in the depth dimension in terms of the binocular disparity cue, were accompanied by multiple auditory stimuli. Observers reported the number of visual stimuli (Experiments 1 and 2) and the displacement of the apparent motion that was defined by the distance between the first and last visual stimuli (Experiment 2). When the number of auditory stimuli was more/less than that of the visual stimuli, observers tended to perceive more/less visual stimuli and a larger/smaller displacement than when the numbers of the auditory and visual stimuli were the same, regardless of the dimension of motion. These results suggest that auditory stimulation may modify the visual processing of motion by modulating the spatiotemporal resolution and extent of the displacement.     

Integrated memory for objects, places, and temporal order: evidence for episodic-like memory in mice

Human episodic memory refers to the recollection of an unique past experience in terms of what happened, and where and when it happened. Factoring out the issue of conscious recollection, episodic memory, even at the behavioral level, has been difficult to demonstrate in non-human mammals. Although, it was previously shown that rodents can associate what and when or what and where information given on unique trials, it proved to be difficult to demonstrate memory for what, where, and when simultaneously in mammals, without using extensive training procedures, which might induce semantic rather than episodic memory recall. Towards the goal of an animal model of human episodic memory we designed an three-trial object exploration task in which different versions of the novelty-preference paradigm were combined to subsume (a) object recognition memory, (b) the memory for locations in which objects were explored, and (c) the temporal order memory for object presented at distinct time points. We found that mice spent more time exploring two "old familiar" objects relative to two "recent familiar" objects, reflecting memory for what and when and concomitantly directed more exploration at a spatially displaced "old familiar" object relative to a stationary "old familiar" object, reflecting memory for what and where. These results suggest that during a single test trial the mice were able to (a) recognize previously explored objects, (b) remember the location in which particular objects were previously encountered, and (c) to discriminate the relative recency in which different objects were presented. According to the currently discussed behavioral criteria for episodic-like memory in animals, our results suggest that mice are capable to form such higher order memories.     

The internal environment of knowledge claims: One aspect of the knowledge-society connection

In the sociology of knowledge, the relationship between society and knowledge —or rather what separates them — remains an unsolved problem. A critical analysis of various solutions that we must look for to this problem suggests the plausibility of a passage between social groups, styles of argumentation and objects of knowledge. An empirical model of decision displacements is proposed on the basis of a corpus of texts and of observations derived from concrete analysis of a laboratory situation.     

A methodological review of preference displacement research

The purpose of this review was to identify and compare methodological components of preference displacement research and outcomes. We coded, categorized, and defined patterns of preference displacement for a total of 133 participants across 10 studies. We found that patterns of displacement differed within and across studies, and over 46% of participants did not engage in patterns of displacement. Therefore, the commonly held notion that edible stimuli are more likely to displace tangible stimuli is not as ubiquitous as once thought. However, due to considerable variation in methodology and reporting across reviewed studies, it is difficult to determine what variables may be responsible for obtained study outcomes. We conclude that future researchers consider the importance of each methodological variable coded in our review, and make methodological decisions in the context of the research question they are looking to answer. We also provide additional suggestions for future research and clinical practice.
