Feminist Therapy Pioneer: E. Kitch Childs

ABSTRACT

This article will focus on the life of the late Dr. E. Kitch Childs and her impact on Feminist Therapy. It seeks to celebrate and pay homage to her as one of the pioneers who helped pave the way for women in therapy. Dr. Childs was an African American lesbian woman who stood in the gap for social justice with her intellect, tenacity, and bravery and took the lead as a radical visionary.     

Shedding Dialectical Tiers: A Social-Epistemic View

Is there a duty to respond to objections in order to present a good argument? Ralph Johnson argues that there is such a duty, which he refers to as the “dialectical tier“ of an argument. I deny the (alleged) duty primarily on grounds that it would exert too great a demand on arguers, harming argumentation practices. The valuable aim of responding to objections, which Johnson 's dialectical tier is meant to satisfy, can be achieved in better ways, as argumentation is a social-epistemic activity.

THOMAS MERTON AND LEO SZILARD: THE PARALLEL PATHS OF A MONK AND A NUCLEAR PHYSICIST

Abstract Thomas Merton and Leo Szilard, two of the seminal religious and scientific figures of the twentieth century, briefly connected on the issue of the danger of atomic weaponry. This meeting resulted from paths that guided them to an “orbiting” or distancing from human society through a phase of intellectual (Szilard) or spiritual (Merton) abstraction followed by a return to the concerns of human society. These parallel trajectories and their eventual intersection reflect both the similarities and differences in their respective backgrounds. The briefness of their contacts and the unfulfilled possibilities from such contacts also suggest the importance of a continuing dialogue between major figures in religion and science.     

Preserving integrity against colonization

Genuine reconciliation between first- and third-person methodologies and knowledge requires respect for both phenomenological and scientific epistemologies. Recent pragmatic, theoretical, and verbal attempts at reconciliation by cognitive scientists compromise phenomenological method and knowledge. The basic question is thus: how do we begin reconciling first- and third-person epistemologies? Because life is the unifying concept across phenomenological and cognitive disciplines, a concept consistently if differentially exemplified in and by the phenomenon of movement, conceptual complementarities anchored in the animate properly provide the foundation for reconciliation. Research by people in neuroscience and in dynamic systems theory substantiate this thesis, providing fundamental examples of conceptual complementarity between phenomenology and science.     

中小学生阅读寓言过程的眼动研究

研究用眼动记录仪对小五、初二和高二年级各20名视力正常学生阅读难、易两种寓言材料的眼动过程进行了记录。结果发现：1．无论是对同一难度寓言阅读理解成绩的差异还是眼动模式的差异,在小五与初二之间显著,在初二与高二之间不显著,这说明对寓言真正理解的年龄在初中,高中只是进一步完善阶段;2材料难度对不同年级学生的眼动模式有一定影响．分别影响小学生的眼跳距离、初中生的注视次数和高中生的注视点持续时间。     

Proof theory and mathematical meaning of paraconsistent C-systems

A proof-theoretic analysis and new arithmetical semantics are proposed for some paraconsistent C-systems, which are a relevant sub-class of Logics of Formal Inconsistency (LFIs) introduced by W.A. Carnielli et al. (2002, 2005) [8] and [9]. The sequent versions BC, CI, CIL of the systems bC, Ci, Cil presented in Carnielli et al. (2002, 2005) [8] and [9] are introduced and examined. BC, CI, CIL admit the cut-elimination property and, in general, a weakened sub-formula property. Moreover, a formal notion of constructive paraconsistent system is given, and the constructivity of CI is proven. Further possible developments of proof theory and provability logic of CI-based arithmetical systems are sketched, and a possible weakened Hilbert?s program is discussed. As to the semantical aspects, arithmetical semantics interprets C-system formulas into Provability Logic sentences of classical Arithmetic PA (Artemov and Beklemishev (2004) [2], Japaridze and de Jongh (1998) [19], Gentilini (1999) [15], Smorynski (1991) [22]): thus, it links the notion of truth to the notion of provability inside a classical environment. It makes true infinitely many contradictions B∧¬B and falsifies many arbitrarily complex instances of non-contradiction principle ¬(A∧¬A). Moreover, arithmetical models falsify both classical logic LK and intuitionistic logic LJ, so that a kind of metalogical completeness property of LFI-paraconsistent logic w.r.t. arithmetical semantics is proven. As a work in progress, the possibility to interpret CI-based paraconsistent Arithmetic PACI into Provability Logic of classical Arithmetic PA is discussed, showing the role that PACIarithmetical models could have in establishing new meta-mathematical properties, e.g. in breaking classical equivalences between consistency statements and reflection principles.     

Impaired awareness of movement disorders in Parkinson’s disease

Background

This study analyzed the presence of awareness of movement disorders (dyskinesias and hypokinesias) in 25 patients with Parkinson’s disease (PD) and motor fluctuations (dyskinesias, wearing off, on–off fluctuations). Of the few studies that have dealt with this topic, none have analyzed the differences in the awareness of motor deficits by comparing the on and off states using motor scales and an extensive battery of tests to assess cognitive and behavioral functioning.

Methods

PD patients were compared on three different scales that we have devised to measure awareness of movement disorders: Global Awareness of Movement (GAM) Disorders, dyskinesia/hypo-bradykinesia rating scales.

Results

Data showed that PD patients had greater awareness and psychological suffering in the off state than in the on state. In particular, they were troubled by motor disabilities related to hypokinesias and had mood-related symptoms and a perception of disability in activities of daily living. Interestingly, patients only showed a selective reduction of awareness of movement disorders associated with executive functions and related to dyskinesias in the on state, compared to a preserved awareness of hypokinesias in the off state. On the contrary, no association with executive functions was found in the off state.

Conclusion

Our findings suggest that the dopaminergic overstimulation of mesocorticolimbic pathways may cause a dysfunction of prefrontal–subcortical connections related to the impaired insight.     

Fitts’ law holds for pointing movements under conditions of restricted visual feedback

Fitts’ law robustly predicts the time required to move rapidly to a target. However, it is unclear whether Fitts’ law holds for visually guided actions under visually restricted conditions. We tested whether Fitts’ law applies under various conditions of visual restriction and compared pointing movements in each condition. Ten healthy participants performed four pointing movement tasks under different visual feedback conditions, including full-vision (FV), no-hand-movement (NM), no-target-location (NT), and no-vision (NV) feedback conditions. The movement times (MTs) for each task exhibited highly linear relationships with the index of difficulty (r² > .96). These findings suggest that pointing movements follow Fitts’ law even when visual feedback is restricted or absent. However, the MTs and accuracy of pointing movements decreased for difficult tasks involving visual restriction.     

词汇获得年龄效应的眼动研究

采用两个实验考察了获得年龄因素在汉语词汇识别中的作用。实验一采用经典的词汇判断任务考察了获得年龄和词频因素在词汇判断中的作用,结果发现获得年龄和词频两个因素均影响词汇识别。实验二采用阅读句子任务,通过实时记录的眼动追踪技术进一步考察了在有语境的情况下,获得年龄和词频因素在词汇加工中的作用。结果发现,在阅读句子任务中,词汇获得年龄和词频因素都在词汇加工中起作用,二者存在交互作用,晚获得词存在词频效应。两个实验的结果均支持了在汉语词汇识别中,存在获得年龄效应。
