Lower eyelid hernia repair for palpebral bags: a comparative study

The standard treatment for herniated "bags" of the lower eyelid is surgical removal of excess fat. Sachs and Bosniak in 1986 and de la Plaza and Arroyo in 1988 described a new technique for treatment of palpebral bags that consisted of returning the herniated fat to the orbital cavity and retaining it by continuous sutures of the capsulopalpebral fascia either to the dehiscent portion of the orbital septum or to the periosteum of the lower orbital rim. This article reports a prospective study of 26 patients who underwent standard blepharoplasty in one lower eyelid and capsulopalpebral fascia hernia repair in the other lower eyelid. All were evaluated at 6 weeks and at 6 months after surgery, and the outcomes were compared. The results of the two different techniques in the same patient have shown comparable aesthetic outcomes in the treatment of palpebral bags. However, results indicate that the capsulopalpebral fascia hernia repair technique carries less discomfort and pain during the operation and may be less prone to postoperative bleeding and hematoma formation. In addition, in contrast to standard lower blepharoplasty with fat resection, hollowing of the lower lid or potential sunken appearance of the globe may remain absent with capsulopalpebral fascia hernia repair beyond the 6-month period of this study.     

The effects of observational feedback on treatment integrity in school-based behavioral consultation.

Evaluated the effects of performance feedback on levels of treatment integrity in school-based behavioral consultation. Three teachers employed in a residential treatment community were responsible for treatment implementation. Treatment integrity was defined as the percentage of 2-min intervals during which contingent teacher reinforcement for student on-task behavior was directly observed. Teacher and child behavior were monitored across baseline, traditional consultation, and consultation with performance feedback conditions in a multiple baseline design. Following a Problem Identification Interview and Problem Analysis Interview (J. R. Bergan, 1977), mean levels of treatment integrity for the 3 teachers ranged from 9% to 37%. The addition of a performance feedback package increased treatment integrity for all 3 teachers to levels ranging from 60% to 83%. The findings contribute to a growing literature supporting the need for direct assessment of treatment integrity in school-based consultation research and practice.

Visual conversion disorder: A case analysis of the influence of visual information.

We examined the influence of visual information on a decision task that was administered to an individual with monocular visual conversion disorder. Findings indicated that his performance was influenced by the visual information and by motivation instructions. The findings are discussed in terms of a model of hysterical blindness that recognizes the interplay of cognitive and motivational processes.

Under what conditions are observed intercorrelations greater or smaller than true intercorrelations?

Two possible explanations were examined for finding that observed correlations among dimensions are sometimes greater than and sometimes less than true intercorrelations: It can be explained by (a) variation in true halo or (b) in terms of individual differences in perceived similarities among dimensions. Subjects (N?=?145) viewed videotapes that exhibited either high or low true halo, rated them, and rated similarities among dimensions. True halo level accounted for significant variance in rating intercorrelation, but perceived similarity did not. Results suggest that neither explanation is adequate to account for the finding that observed intercorrelations can either overestimate or underestimate true intercorrelations.

The cost of good fortune: When positive life events produce negative health consequences.

Previous research regarding the effects of positive life events on physical health has been inconclusive. We tested the hypothesis that positive life events have a detrimental effect on health only among people with negative self-views. This prediction derives from an identity disruption model of stress, which holds that an accumulation of life events that are inconsistent with the self-concept leads to physical illness. To test the hypothesis, we conducted 2 prospective studies in which positive life events and self-esteem were used to predict the development of illness over time. In accordance with predictions, both studies showed that desirable life changes were associated with increases in illness only among Ss with low self-esteem; among Ss with high self-esteem, positive life events were linked to better health. Implications for understanding the manner in which life events affect health are considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An illusion of memory: False recognition influenced by unconscious perception.

The results of two experiments showed that an illusion of memory can be produced by unconscious perception. In a first phase of those experiments, a long list of words was presented for study. For the test of recognition memory given in the second phase of each experiment, presentation of a "context" word preceded that of most recognition test words. Ss were to judge whether or not the test words had been presented during the earlier study phase of the experiment. Effects of a context word on this recognition memory decision were opposite when Ss were aware vs. unaware of its presentation. For example, as compared to a condition in which no context word was presented, the probability of false recognition was increased when Ss were unaware but decreased when Ss were aware of the presentation of a context word that matched the recognition test word. Results are discussed in terms of unconscious influences on an attribution process. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Decision Support System for Residential Land Development Site Selection Process

An important phase within the overall residential land development process is preliminary project planning, which is a highly coordinated effort involving a number of decisions that are made by a variety of individuals. One critical decision faced by the project owner and the development team, during the preliminary planning phase, is the initial selection of the most appropriate site for a proposed conceptual development plan. The scope of this paper deals with (1) formulating a model for the preliminary planning phase of residential site selection; and (2) developing an associated decision support system that can assist the decision makers during this phase of the project. The analytical hierarchy process was the decision making theory used in the site selection decision support system. Analytical hierarchy process uses a hierarchical structure comprising both quantitative and qualitative factors that are based on factual data and the knowledge and experience of the decision makers.     

Cognitive factors differentiating attention deficit–hyperactivity disorder with and without a comorbid mood disorder.

Mood disorders and attention deficit–hyperactivity disorder (ADHD) co-occur in 20–30% of children and adolescents diagnosed in both epidemiological and clinical studies, but little information is available regarding cognitive factors that may be relevant to the expression of co-occurring mood disorders and ADHD. This study examined whether ADHD with and without a comorbid mood disorder could be differentiated on the basis of cognitive factors associated with prominent theories of depression. Children meeting diagnostic criteria for ADHD (n?=?14) or ADHD and a comorbid mood disorder (n?=?27) were assessed on a variety of cognitive indices. Children in the comorbid group reported more negative views of themselves and a more depressogenic attributional style. Cognitive disturbances associated with A. T. Beck's (1967) cognitive model and attributional style theories of depression differentiate ADHD children with significant mood pathology.

The transient to steady-state transition during the spray-rolling process

From the geometrical standpoint, this article presents a qualitative theoretical analysis and prediction of the transient to steady-state transition during the spray-rolling process, a novel manufacturing technique for aluminum strips. The analytical results indicate that, when the deposited materials at the specific points on one roll surface overlap their counterparts on the other roll surface, spray rolling transits from the transient state to the steady state. The specific points are the limiting deposition positions of the atomized droplets on the roll surface initially.
