Divine Infinity in Thomas Aquinas: I. Philosophico-Theological Background

A reassessment of Aquinas's doctrine of divine infinity, particularly in the light of the previous history of the concept within Western philosophy and theology. From the critical perspective provided by this history the central place which has been claimed for it in Aquinas's thinking is questioned, as are also its originality and coherence. The notion that the doctrine of divine infinity was introduced to Western thought by Judaeo-Christianity is rejected; from Anaximander onwards it had been a central concept in Greek philosophy. Aristotle however had rejected it so effectively that, for several centuries afterwards, it seems to have led an 'underground' existence until it finally surfaces again in 'Gnostic' and related currents of thought. It is from these circles that it finally, and after some resistance, patchily entered orthodox Christian thinking. Likewise Plotinus was not the source of the doctrine, as some have claimed; historical precedence must be given to the Gnostics. Neoplatonism never, despite the prestige of Plotinus, fully accepted the doctrine; in Proclus it is a subordinate emanation from the One, which is beyond Infinity and Infinitude. Nor, because of the influence of Aristotle, does Islamic Neoplatonized Aristotelianism endorse the doctrine. Aquinas's commitment to it seems to stem from the impact of John of Damascus's stress upon the doctrine, the translation of whose work greatly influenced Western theology from the late twelfth century onward, together with his need to distance himself from the restrictions of the divine power and freedom found in the Arabic Aristotelian philosophers, whom, in general, he regarded as philosophical authorities. But his position on the doctrine is flawed by equivocation and self-contradiction, flowing from his attempt to reconcile Christian personalist theism with Neoplatonized Aristotleain necessitarian monism.     

MULTICOMPONENT INTERVENTION FOR AGITATED BEHAVIOR IN A PERSON WITH ALZHEIMER'S DISEASE

We evaluated a multicomponent intervention for agitated behavior in a man with probable Alzheimer's disease. Hypotheses about variables controlling his agitated behavior guided intervention design. Based on staff interviews, direct observations, and brief experimental probes, intervention components were chosen to increase rate of reinforcement and decrease aversive aspects of his job. Intervention reduced agitated behavior without disrupting his work rate.     

Effects of temperature and prior residence on territorial aggression in the convict cichlid Cichlasoma nigrofasciatum

Aggression in the convict cichlid Cichlasoma nigrofasciatum was measured under two different environmental parameters after introduction of a conspecific intruder. Measurements were made after 24-hr and 48-hr teritorial residence times at both 26°C and 30°C. Eight fish established territories in individual tanks each containing one terra cotta pot. Intruders contained in a glass cylinder were introduced into the territories. An opaque divider separating the resident from the intruder was removed after a 15-min acclimation period. At 26°C, we observed a significant difference in the mean number of bites of the cichlids of 24-hr and 48-hr residency durations, whereas, at 30°C, such a difference did not exist. Statistical analysis showed that cichlids exhibited more aggression at 30°C than at 26°C. Increased aggression levels at the higher temperature may be related to the fact that cichlids establish territories and spawn at about 30°C.     

No evidence of other-race effect for Chinese faces in Malaysian non-Chinese population

The other-race effect (ORE) reflects poor recognition of faces of a different race to one's own. According to the expertise-individuation hypothesis, this phenomenon is a consequence of limited experience with other-race faces. Thus, similar experience with own and other-race faces should abolish the ORE. This study explores the ORE in a multi-racial country (i.e., Malaysia) by comparing Malaysian observers' face recognition for faces of a predominant racial group in Malaysia (i.e., Chinese) with faces from an uncommon group (i.e., Caucasian). Malaysian Chinese, Malays, and Malaysian Indians completed the Cambridge Face Memory Test (CFMT) and the CFMT-Chinese. Compared with the normative scores, Malaysian observers showed poor performance in the CFMT-Caucasian. Interestingly, Malays and Malaysian Indians observers' performance was identical to that of Malaysian Chinese in the CFMT-Chinese and to the normative scores of the test. These results demonstrate the relevance of experience in shaping the ORE.     

Expressed emotion and attributions in the carers of patients with Alzheimer's disease: the effect on carer burden

Burden of care, expressed emotion (EE), causal attributions, and salivary cortisol were assessed in 100 carers of patients with Alzheimer's disease. Forty-one carers were rated high EE, which was associated with higher scores of carer distress and strain, and greater reports of noncognitive features in the patient, but not with cortisol levels. High EE carers made more attributions personal to, and controllable by, the patient for negative events. Critical carers made more attributions of the patient's behavior that was idiosyncratic. Warmth toward the patient was associated with the opposite of this pattern. Overinvolved carers made attributions of the patient's behavior to causes external to the patient and internal to themselves. Cortisol levels were associated with self-reports of strain and distress.     

Differences in postural control and movement performance during goal directed reaching in children with developmental coordination disorder

Poor upper-limb coordination is a common difficulty for children with developmental coordination disorder (DCD). One hypothesis is that deviant muscle timing in proximal muscle groups results in poor postural and movement control. The relationship between muscle timing, arm motion and children's upper-limb coordination deficits has not previously been studied. The aim of this study was to investigate the relationship between functional difficulties with upper-limb motor skills and neuromuscular components of postural stability and coordination. Sixty-four children aged 8-10 years, 32 with DCD and 32 without DCD, participated in the study. The study investigated timing of muscle activity and resultant arm movement during a rapid, voluntary, goal-directed arm movement. Results showed that compared to children without DCD, children with DCD took significantly longer to respond to visual signals and longer to complete the goal-directed movement. Children with DCD also demonstrated altered activity in postural muscles. In particular, shoulder muscles, except for serratus anterior, and posterior trunk muscles demonstrated early activation. Further, anterior trunk muscles demonstrated delayed activation. In children with DCD, anticipatory function was not present in three of the four anterior trunk muscles. These differences support the hypothesis that in children with DCD, altered postural muscle activity may contribute to poor proximal stability and consequently poor arm movement control when performing goal-directed movement. These results have educational and functional implications for children at school and during activities of daily living and leisure activities and for clinicians assessing and treating children with DCD.     

A confirmatory factor analysis on the DSM-IV ADHD and ODD symptoms: what is the best model for the organization of these symptoms?

Confirmatory factor analysis (CFA) was used to evaluate five different models for the organization of the DSM-IV ADHD and oppositional defiant disorder (ODD) symptoms (Model 1: a single factor model; Model 2: an ADHD and ODD two factor model; Model 3a: an inattention (INA), hyperactivity/impulsivity (HYP/IMP), and ODD three factor model; Model 3b: an INA, HYP/IMP, and ODD three factor model where the three IMP symptoms cross-load on the ODD factor; Model 4: an INA, HYP, IMP, and ODD four factor model). To evaluate these models, maternal ratings of ADHD and ODD symptoms were obtained at outpatient pediatric clinics on 742 children not in treatment and 91 children in treatment for ADHD. Model 3a resulted in a good fit as well as a significantly better fit than Model 2. Model 3a was also equivalent across treatment status, gender, and age groupings for the most part. Though Models 3b and 4 provided a statistically better fit than Model 3a, the improvement in fit was small and other model selection criteria argued against these more complex models.
