Summary:
The magnetic dichroism effect can be obtained from the cross section difference between up and down spins. The calculation needs the results of phase shift, initial and final state wave functions, however when the phase shift is zero the transition matrix elements in atomic and crystal contribution would be singular, therefore we need some means of numerical treatment to handle the problem. In this paper, we describe the way to renormalize the wave function the we recalculate the matrix element of spin-orbit operator , the atomic contribution and the cross section difference between up and down spins. We and that all functions behave regularly on all energy range even though the
phase shift is zero. This result is in accordance with the MXD of FCC iron.

Harga : Rp 0,-
ABSTRAK :
Objective: Compare behavioral and emotional problems of children and adolescents with Prader-Willi Syndrome (PWS) and dients consulting mental health centers (MHC) and related behavioral and emotional problems to the children's personality in the PWS group.
Methods: Participants were 39 children with PWS and 585 matched MHC dients. Child Behavior Checklist (CBCL) syndromes were related to the Big-Five personality factors measured with the California Child Q-sort (CCQ).
Results: Mean CBCL Total Problems scores were not different for the PWS and MHC groups, but differences were found for several of the CBCL subscales. Patterns of correlations among CBCL scales were similar In both groups, although coefficients were generally higher in the PWS group, indicating higher comorbidtty or co-absence of CBCL syndromes in children and adolescents with PWS. Personality profiles were specific for Internalizing and Externalizing problems of children and adolescents with PWS.
Key words: Prader-Willi Syndrome; Child Behavior Checklist (CBCL); California Child Q-sort (CCQ); Big Five personality factors; externalizing; internalizing.

Behavior Problems in Children With Diabetes: Disentangling Possible Scoring Confounds on the Child Behavior Checklist

ABSTRAK :
Objective: The Child Behavior Checklist (CBCL; T. M. Achenbach, 1991), when used to assess the behavior of children with diabetes, may contain confounds because some behavioral items can have a physiologic etiology, and may skew reports of behavioral disturbance.
Methods: Two techniques were used to disentangle possible scoring confounds in the behavioral ratings of children with and without diabetes: (1) the Somatic Complaints scale was deleted, or (2) Diabetes Items, identified a priori with 89% agreement by nine medical personnel, were deleted.
Results: As expected, with traditionally scored protocols, children with diabetes obtained higher Internalizing and Total Behavior Problem scores than controls. This group difference persisted whether the Somatic Complaints scale or the Diabetes Items were deleted.
Conclusions: Compared to controls, children with diabetes obtained mildly elevated scores on six of the eight CBCL scales, regardless of scoring method, suggesting that their mildly elevated behavioral profile is not confounded by physiologic symptomatology.
Key words: diabetes; Child Behavior Checklist; chronic illness.

Behavior Problems Associated with Sleep Disordered Breathing in School-Aged Children—the Tucson Children’s Assessment of Sleep Apnea Study

ABSTRAK :
Objective The purpose of the current study was to examine prevalence of and relations between a commonly used measure of nighttime breathing problems, the Respiratory Disturbance Index (RDI), and a range of problem behaviors in community children. Methods Participants were 403 unreferred children aged 6–12 years. Recruitment was completed through public elementary schools. Overnight unattended in-home polysomnography was used to assess sleep and breathing. The RDI was used as the indicator of respiratory events during sleep. The Child Behavior Checklist and the Conners’ Parent Rating Scales-Revised were used to assess behavior. Results Prevalence rates for Attention, Cognitive Problems, Aggression, Oppositional behavior, and Social Problems were greatest for subjects with high RDIs. Prevalence for Internalizing behaviors was not greater for those subjects with high RDIs. Hyperactivity was not strongly related to higher RDIs. Conclusions Behavioral problems may exist in the presence of nocturnal breathing events in unreferred children. Specific patterns of behavioral morbidity have still not been established. Some behaviors, such as hyperactivity, may show differing sensitivity and specificity in relation to the RDI.
Key words behavior; children; Child Behavior Checklist; Conners’ Parent Rating Scales— Revised; prevalence; Respiratory Disturbance Index; sleep disordered breathing.

Abstract — Aim: Contradictory results have been produced by previous research on the question to what extent do children of alcoholics (COAs) differ in measures of externalizing symptoms from children of non-alcoholic parents. The goal of this study was to determine whether COAs are characterized by more behavioural problems than non-COAs, and also to determine the influence of a paternal antisocial personality disorder (ASPD) in this context. Methods: In this study, 340 children and adolescents between the ages of 11 and 18 years and their parents were included. Of this sample, 76 adolescents showed a positive family history of alcoholism (FHalc) and 47 adolescents a positive history of a paternal ASPD (FHaspd). Externalizing symptoms, which where measured on the basis of maternal ratings and self-assessments, were analysed with a two-factorial MANCOVA with FHalc and FHaspd as independent factors. Results: The results of the MANCOVA revealed that only children with paternal ASPD showed significant higher scores in attentional problems, self-rated aggression/delinquency and disruptive behaviour, while there were no differences for FHalc and the interaction effect. Conclusions: Our findings show that the higher of behavioural problems relates primarily to a higher prevalence in both cases of ASPD among fathers. These results were discussed regarding the mediating role of a paternal ASPD for the differences in behavioural problems in COAs and non-COAs. Furthermore, children with FHalc and/or FHaspd represent high-risk groups and should be the focus of prevention and intervention measures.

EMOTIONAL INTERPLAY AND DOMINANT PERSONALITIES IN THERAPEUTIC GROUPS: OBSERVATIONS ON COMBINED SCHIZOPHRENIC-NEUROTIC GROUPS
Kode Jurnal : JPSIE-0006
Kategori : Psikologi
Jumlah Halaman : 18
Harga : Rp 0,-
SUMMARY :
1 . The response of male schizophrenic patients to a therapeutic group setting is reported. Two groups were observed ; in Group I the schizophrenics equalled, in Group II they outnumbered the other participants.
2. Group II was disrupted by strong feelings of hostility which were directed against one of the attending schizophrenics ; the group eventually broke into two unequal parts when all the other schizophrenic patients insisted on being seen as a separate group.
3. Inter-personal relations in a group can be multilateral. The span of awareness for multilateral contacts seems to be limited, however ; if they are too numerous the idea of a group configuration replaces the awareness of distinct personalities.
4. The emotional response aroused through inter-personal relations in a group appears to be of the same character as in individual psychotherapy.
5. There is, however, the difference that a group setting offers a feeling of greater social security and emotional support than individual interviews to tongue-tied patients, and particularly to schizophrenics.
6. The risk that patients, and especially schizophrenics, may “ act out” emotional difficulties seems to be greater in group than in individual treatment.
7. The emergence of dominant personalities seems to be a general characteristic of groups with a common purpose. Some of the factors which may lead to dominance have been tentatively considered. Dominance in human groups may have a pathological origin.
