The shamanic narrative in the postmodern age

Abstract

The current effacement of a deterministic, universal, scientific narrative to explain and control reality has left in its place a play of alternative narratives. The range of these explanations starts in a philosophical discourse we call deconstruction, an epistemology of textual criticism previously restricted to literary analysis. Now the entire infrastructure inherited from classic mechanics is being called into question, including its totalizing positivistic off‐shoots in the social sciences, leaving uncertain what is real, actual, or true. In this competition of narratives, the shamanic explanation provides additional answers to these categories. It distinguishes itself from alternative versions by a drive to bridge and unify the naterial here‐and‐now and the non‐material otherworld.     

Interpersonal Perceptions and Metaperceptions in Dialogic Action Therapy: A Relational Methodological Approach to Theory Construction

Abstract

Two forms of understanding in theories of therapy are identified: empathic understanding rooted in individualism, and reality-based understanding that acknowledges the relational character of human existence. We argue for regarding these two forms of understanding as complementary. This requires a paradigmatic shift from methodological individualism to methodological relationalism, which asserts that the analysis of role relationships precedes that of individuals and situations. Informed by methodological relationalism, dialogic action therapy accords prominence to the creation of a therapeutic relationship between therapist and client, between whom bidirectionality of perceptions is inherent. We develop a formal analytic scheme for theory building. Six major constructs, degrees of perception, directionality, agreement, reciprocity, accuracy, and congruence, are employed to facilitate the analysis of therapist and client perceptions and metaperceptions of trust in depth. The implications for therapy and methodology of measurement are discussed.     

Does Multitasking Impair Studying? Depends on Timing

It is often said that contemporary students frequently study while ‘multitasking’. However, this rather diffuse term encompasses situations that vary as to the whether the learner controls the pace at which educational materials are provided. On the basis of prior cognitive research, we hypothesize that this may well be a critical determinant of interference. Three studies required students to read or listen to several short historical narratives and also to engage in five to eight very short conversations (akin to an instant messaging conversation). In Experiment 1, subjects read the narratives; here, multitasking marginally increased total time spent reading the narratives, especially when it occurred at random times. However, final memory for the narratives was not significantly affected. Similar results were obtained when the narratives were presented in audio format and the learner could pause them while conversing (Experiment 2). By contrast, when audio narratives did not pause, interruptions reduced comprehension performance (Experiment 3). Copyright © 2013 John Wiley & Sons, Ltd.     

The Martyrdom Effect: When Pain and Effort Increase Prosocial Contributions

Most theories of motivation and behavior (and lay intuitions alike) consider pain and effort to be deterrents. In contrast to this widely held view, we provide evidence that the prospect of enduring pain and exerting effort for a prosocial cause can promote contributions to the cause. Specifically, we show that willingness to contribute to a charitable or collective cause increases when the contribution process is expected to be painful and effortful rather than easy and enjoyable. Across five experiments, we document this “martyrdom effect,” show that the observed patterns defy standard economic and psychological accounts, and identify a mediator and moderator of the effect. Experiment 1 showed that people are willing to donate more to charity when they anticipate having to suffer to raise money. Experiment 2 extended these findings to a non‐charity laboratory context that involved real money and actual pain. Experiment 3 demonstrated that the martyrdom effect is not the result of an attribute substitution strategy (whereby people use the amount of pain and effort involved in fundraising to determine donation worthiness). Experiment 4 showed that perceptions of meaningfulness partially mediate the martyrdom effect. Finally, Experiment 5 demonstrated that the nature of the prosocial cause moderates the martyrdom effect: the effect is strongest for causes associated with human suffering. We propose that anticipated pain and effort lead people to ascribe greater meaning to their contributions and to the experience of contributing, thereby motivating higher prosocial contributions. We conclude by considering some implications of this puzzling phenomenon. Copyright © 2011 John Wiley & Sons, Ltd.     

Team Perceived Trustworthiness in a Complex Military Peacekeeping Simulation

Antecedents to trust (propensity to trust, perceived trustworthiness) and trust behaviors were examined in relation to team performance in a complex eight-mission military peacekeeping simulation. Teams were colocated or distributed and stayed in the same or transferred to a different context at task transfer. In Experiment 1, an ability and competence factor accounted for most of the variance in perceived trustworthiness and greater perceptions of teammates' abilities/competences predicted posttransfer performance. One's perception of how others perceived one's ability/competence increased over missions. In Experiment 2, propensity to trust did not predict performance; however, trust in others' and one's own ability/competence and trust behaviors predicted performance. At task and/or context transfer, teams produced more monitoring and less cooperating language in their communication.     

Parenting and the dysregulation profile predict executive functioning in children with acquired brain injury

Background: Children with acquired brain injury (ABI) present with high rates of psychological disorders commonly accompanied by deficits in hot and cold executive functions (EFs). Impairments in EFs have been reported to precede mental health problems. Moreover, children who are vulnerable to developing mental health problems in adulthood frequently present with a dysregulation profile in childhood, characterized by impairments in cognitive, behavioral and emotional regulation. Objective: To identify profiles of behaviors associated with impairment in hot and cold EFs and compare injury factors, environmental stressors and dysregulation profile between them. Methods: A latent profile analysis was conducted with 77 children with ABI aged between 6 and 12. Injury factors, child IQ, environmental stressors and the dysregulation profile were compared between these behavioral profiles. Logistic regressions were conducted to predict profile membership. Results: Two profiles were identified: Profile M, with mild deficits (1–2 SD above the mean) in working memory and social skills, and profile C, presenting clinically significant deficits (2–3 SD above the mean) in shift, initiate, working memory, planning and social skills and mild deficits in inhibit, emotional control and task monitor. Proximal environmental stressors (dysfunctional parenting practices, parental stress, parent’s executive dysfunction, anxiety-trait, and depressive symptoms) and dysregulation symptoms predicted profile membership, whereas injury factors, child IQ and distal environmental stressors did not. Conclusion: Following ABI, children with profile C are at risk of mental health problems and present with more proximal stressors. The dysregulation profile may be useful as a proxy for risk for later mental health problems in children with ABI.     

The fatigue limits of copper single crystals cyclically deformed at constant plastic strain amplitudes

Based on systematic surface observations, experimental measurements on the fatigue limits of differently oriented copper single crystals cyclically deformed at constant plastic strain amplitudes are summarized, and an orientation dependence of the fatigue limit is sketched. It was found that the fatigue limits of crystals depend mainly upon the low-strain-amplitude dislocation structures, which are characteristic of the particular crystal orientations. When multiple-slip deformation is the main mode of deformation and ultimately produces stable lowenergy dislocation structures such as labyrinth and cell structures, the fatigue limit can be improved notably.     

Approximant phases,phason planes and domain-boundary networks in Al−Ni−Rh alloys

Structurally complicated ξ′- and ξ-phases have been found, for the first time, in as-cast Al₇₃Ni₅Rh₂₂ and Al₇₅Ni₁₅Rh₁₀ alloys. The lattice parameters of these two phases were determined by means of electron diffraction and high-resolution transmission electron microscopy (HREM). These two phases have similar orthorhombic structures but with different lattice parameters of a?=?23.2?Å, b?=?16.4?Å, c?=?12.0?Å for the ξ′-phase and a?=?20.3?Å, b?=?16.4?Å, c?=?14.8?Å for the ξ-phase. A new two-dimensional domain-boundary network has also been observed in these two phases. Domain boundaries with normals closely parallel to the [001] direction are actually phason planes represented by a translation vector of r?=(1/2)a?+(1/2τ)c in the ξ′-phase and r=±(1/2τ²) a?+(τ/2)c in the ξ-phase, whereas the newly-found wide and zigzag boundaries perpendicular to the above set were attributed from the step-like boundary structures of domains related by a translation vector of r?=(1/τ)((1/2)a?+(1/2τ)c). The structural difference between the two types of planar faults is discussed.     

Unusual stress behaviour of CeO2-doped diamond-like carbon nanofilms

CeO₂-doped diamond-like carbon (DLC) films with thicknesses of 180–200 nm were deposited by unbalanced magnetron sputtering. When the CeO₂ concentration is in the range 5–8%, the residual compressive stress of the deposited films is reduced by 90%, e.g. from about 4.1 GPa to 0.5 GPa, whereas their adhesion strength increases. These effects are attributed to the dissolution of CeO₂ within the DLC amorphous matrix and a widening interface between the DLC film and the Si substrate, respectively.
