Speech disturbances in presenile dementia related to local cerebral blood flow abnormalities in the dominant hemisphere

Ten female patients, age 50–70 years, suffering from presenile dementia and showing signs of defective speech function were analyzed. All patients underwent measurements of regional cerebral blood flow (rCBF) by the xenon clearance technique using a 32-detector piece of equipment, and all showed a marked reduction of the hemisphere mean blood flow level. In addition, regional decreases of blood flow of the gray matter was demonstrated. Patients with a marked reduction in the temporo-parieto-occipital regions showed signs of receptive aphasia including alexia and agraphia. Patients with a marked frontal reduction showed signs of expressive aphasia of various types including stereotyped language, voluble speech, echolalia, and mutism in later stages. The results give further support to our previous conclusion that subsymptoms of presenile dementia, apparently also speech disturbances, can be related to local degenerative changes in the brain, which in their turn are accompanied by local reductions of the blood flow of the gray matter. There is pathoanatomical evidence to support this conclusion.     

Impairment of auditory perception and language comprehension in dysphasia

Men with chronic focal brain wounds were examined for their ability to discriminate complex tones, synthesized steady-state vowels, and synthesized consonant—vowel syllables. Subjects with left hemisphere damage, but not right hemisphere damage, were impaired in their ability to respond correctly to rapidly changing acoustic stimuli, regardless of whether stimuli were verbal or nonverbal. The degree of impairment in auditory processing correlated highly with the degree of language comprehension impairment. The pattern of impairment of the group with left hemisphere damage on these perceptual tests was similar to that found in children with developmental language disorders.     

Center median "alerting" and verbal learning dysfunction

Previous data have shown that stereotaxic center median lesions alone or lesions in the amygdala, unilateral left and right and bilateral, do not impair verbal paired-word associates learning. However, “interactional” combined lesions in the amygdala and center median nucleus on the left side result in a significant decrease in test scores. Analysis of the types of errors made postoperatively by the six patients with this lesion combination indicates the persistence over trials of misnaming errors vs errors of omission. These findings are compatible with hypotheses of an alerting function performed by medial thalamic structures which, for effective learning, cosponsor attention to stimulus cues. Defective alerting is held to result in faulty labeling and subsequent mismatching (see Ojemann, 1975, Brain and Language, 2, 101–120, and Fedio &; Van Buren, 1975, Brain and Language, 2, 78–100).     

TAKING SCIENCE SERIOUSLY WITHOUT SCIENTISM: A RESPONSE TO TAEDE SMEDES

In responding to Taede Smedes, I first examine his thesis that the recent dialogue between science and religion has been dominated by scientism and does not take theology seriously. I then consider his views on divine action, free will and determinism, and process philosophy. Finally I use the fourfold typology of Conflict, Independence, Dialogue, and Integration to discuss his proposal for the future of science and religion.     

REMEMBERING ARTHUR PEACOCKE: A PERSONAL REFLECTION

I join others who have expressed profound gratitude for the life and thought of Arthur Peacocke. I recall some high points in my interaction with him during a period of forty years as an intellectual companion and personal friend. Some similarities in our thinking about evolution, emergence, top‐down causality, and continuing creation are indicated. Four points of difference are then discussed: (1) Emergent monism or two‐aspect process events? (2) Panentheism or process theism? (3) Creation ex nihilo and/or continuing creation? (4) Voluntary or necessary limitation of God's power? Even when we differed I have benefited immensely from our ongoing interaction.     

Émotions et stratégies d’adaptation de prestataires de soins suite à des décès maternels dans le Nord-Kivu

This qualitative study describes the emotional structure and coping strategies associated with maternal death in North Kivu. Based on a heuristic approach, the methodology is based on an iterative process of explicating the experience of maternal death as experienced by the care teams. In conjunction with the transactional model of Lazarus and Folkman, the results focus on four themes: openness to spiritual values, telescoping age identification, use of hygiene strategies and rationalization. The study suggests the establishment of psychological support mechanisms for providers after a maternal death.     

A job-seeking competency model for North Korean defectors who are college students in South Korea

The purpose of this study was to develop a job-seeking competency model for North Korean defectors (NKDs) who are college students in South Korea. This study adopted the Delphi method with a panel of 17 experts, comprising of NKDs who secured their jobs successfully and South Korean field experts who have hired NKDs or assisted them with their employment. Through three Delphi rounds, 18 job-seeking competencies were identified with the definition, behavioural indicators, and competency significance. In addition, the preliminary utility of the competency model was examined. Implications of the study results and future directions for enhancing the validity and utility of the competency model are discussed.     

Rival Methodologies in Emergence Theory: A Non-Dual Approach

Jason Roberts proposes that Karl Rahner's theology of nature serves as an appropriate dialogue partner for natural scientists like Terrence Deacon in his naturalistic approach to the emergence of higher-order levels of existence and activity within the natural sciences. Yet Rahner and Deacon employ different understandings of formal causality in their respective approaches to evolutionary theory: for Rahner, causal agency vis-à-vis constituents; for Deacon, objective constraint on the agency of constituents. Yet a compromise position may be available based on a modest revision of the relationship between societies and their constituent actual entities in A.N. Whitehead's cosmology.     

Beyond androgyny: The emergence of sex-role transcendence as a theoretical construct

Recent trends in sex-role research are reviewed with the purpose of showing a paradigm shift in the kinds of issues and questions thought to be important for an understanding of sex-role development. Two recent advances, conceptualizations of androgyny and sex-role transcendence are described with particular emphasis on the emergence of sex-role transcendence as a new theoretical construct. It is argued that while personality, social-learning, and structural-developmental theories account for sex-role identity and androgyny, only structural-developmental theory provides an adequate conceptual framework for the construct of sex-role transcendence. Questions are raised concerning the empirical demonstration of the concept.
