The use of protection measures in dento-maxillofacial radiology in Europe: a survey among experts.

Patient contact shielding to reduce radiation exposure to radiosensitive organs of patients is known to be used inconsistently in the field of dento-maxillofacial radiology (DMFR). There is an ongoing discussion if its use is still justified with regard to recent technical enhancements in the field. Thus, the aim of this study was to investigate the recommended and applied safety standards regarding dose protection measures in dental radiology within European countries.

Transient dynamics in a nonequilibrium superdiffusive reaction-diffusion process: Nonequilibrium random search as a case study.

Transient regimes, often difficult to characterize, can be fundamental in establishing final steady states features of reaction-diffusion phenomena. This is particularly true in ecological problems. Here, through both numerical simulations and an analytic approximation, we analyze the transient of a nonequilibrium superdiffusive random search when the targets are created at a certain rate and annihilated upon encounters (a key dynamics, e.

A visible light photocatalytic cross-dehydrogenative coupling/dehydrogenation/6π-cyclization/oxidation cascade: synthesis of 12-nitroindoloisoquinolines from 2-aryltetrahydroisoquinolines.

A visible light-induced photocatalytic dehydrogenation/6π-cyclization/oxidation cascade converts 1-(nitromethyl)-2-aryl-1,2,3,4-tetrahydroisoquinolines into novel 12-nitro-substituted tetracyclic indolo[2,1-a]isoquinoline derivatives. Various photocatalysts promote the reaction in the presence of air and a base, the most efficient being 1-aminoanthraquinone in combination with K3 PO4 . Further, the 12-nitroindoloisoquinoline products can be accessed directly from C1-unfunctionalized 2-aryl-1,2,3,4-tetrahydroisoquinolines by extending the one-pot protocol with a foregoing photocatalytic cross-dehydrogenative coupling reaction, resulting in a quadruple cascade transformation.

Employment and self-management: a meta-evaluation of seven literature reviews.

Efforts focused on teaching individuals with intellectual disabilities to manage their own affairs have evolved over the past 30 years. Self-management strategies, in particular, hold much promise when the goal is to promote self-determination. In this article, the authors describe trends in the evolution of self-management strategies by analyzing seven literature reviews.

Predicting quality of life of students who have left special education high school programs.

A subsample (N = 505) was selected from a nationwide, stratified, probability sample of students with disabilities attending high school in 1985. In-school and out-of-school information about these students was obtained in 1987 and 1990 from school records, school personnel, and parents. Conventional item analysis procedures were used to construct a priori quality-of-life composites (social relationships, employment, and independence) from 17 questionnaire variables.

Residential independence of former special education high school students: a second look.

The residential independence of postsecondary students was assessed in 5,462 parents or surrogate parents of students with disabilities from the National Longitudinal Transition Study who had left United States high schools between 1985 and the time of the questionnaire in 1990. An index of residential placement independence served as the dependent variable in a hierarchical regression analysis that featured 43 community, family, student, and school program characteristics entered as block-wise predictors (i.e.

Predicting the earnings of supported employees with mental retardation: a longitudinal study.

A random sample (N = 197) of supported employees with mental retardation was examined in a longitudinal study. Results indicate that intelligence, prior earnings, and federal job subsidy predicted future earnings. Statistical controls applied to the stratified sample show that job placement, job type, subsidy, and means of transportation had little influence on earnings.

Interaction of persons with severe mental retardation and their nondisabled co-workers in integrated work settings.

This investigation matched 23 workers with severe mental retardation to 23 workers without disabilities by job type and minimal duration of employment (at least 6 months) to determine if co-worker relations differed between the two groups of employees. Results indicated that, compared to workers with severe mental retardation, nondisabled workers were more likely to receive information, to receive training, and to interact as friends outside the workplace.

Prediction of residential independence of special education high school students.

The residential independence of post-secondary students was assessed for the 2,686 interviewees of the National Longitudinal Transition Study who had left United States high schools between 1985 and the time of the questionnaire in 1987. An index of residential placement independence was the dependent variable in a regression analysis that featured 37 community, family, student, and school program characteristics entered as block-wise predictors (i.e.

Matched-pairs analysis of co-worker interactions in relation to opportunity, type of job, and placement approach.

Workers with and without disabilities (n = 85) were studied in an effort to determine whether co-worker relations differed between these employees. Few differences were found. Interactions of co-workers without disabilities with their supported co-workers who had disabilities were remarkably similar to their interactions with other co-workers without disabilities in eight of the nine interaction categories investigated.

Cost-effectiveness of supported employment.

Monetary costs and benefits of supported employment to individuals, taxpayers, and society were assessed as was the cost-effectiveness of the nonmonetary benefit, namely, quality of life of employees, as a result of supported employment. Participants were 20 individuals from two Central Illinois agencies serving clients with developmental disabilities. Costs and effects were evaluated using benefit-cost and cost-effectiveness analyses.

Strategies to increase exercise-report correspondence by boys with moderate mental retardation: collateral changes in intention-exercise correspondence.

Correspondence between verbal and nonverbal behavior in an exercise room was taught to 4 13-year-old boys diagnosed with moderate mental retardation. Participants were asked prior to each exercise session which exercise machine(s) they intended to use. No contingencies on stating intentions (promising) were applied.

Analysis of minority-status supported employees in relation to placement approach and selected outcomes.

The employment outcomes of nonminority and minority-status supported employees in the state of Illinois were examined. Results indicated that minority-status supported employees were younger, had higher IQs, and earned more wages per month than did nonminority supported employees. Few differences between minority subgroups were identified.

Descriptive analysis of interactions between co-workers and supported employees.

Varying types of interactions between workers without handicaps and supported employees were described. Results indicated that co-workers interacted extensively with persons who had mental retardation. Surprising findings included high levels of advocacy between co-workers and persons with severe or profound mental retardation and a relatively high percentage of co-workers assuming evaluation and training roles.

Parent involvement in transition programs.

Parent involvement in programs facilitating the transition of persons with handicaps from school to adult life (work, independent living) was examined. The survey found that a significant number of parents were unaware of any transition program for their offspring, although virtually all parents desired involvement of some kind. Parents also indicated preferences relating to their child not living at home upon graduation from school, working in the community, and earning a wage greater than or equal to the minimum.

Benefit-cost analysis of supported employment in Illinois: a statewide evaluation.

A benefit-cost analysis of supported employment in Illinois during Fiscal Year 1987 was presented. Benefits and costs were identified and valued from three perspectives. Society received a $.

Analysis of hours of direct training provided by employment specialists to supported employees.

A repeated measures analysis of the hours of direct training and the ratio of the hours of direct training to the hours worked by supported employees was conducted for two cohorts of supported employees with mental retardation employed for 6 and 12 consecutive months. Results indicated little change in the amount of direct training over time. Type of supported employment significantly affected the amount of direct training provided for both cohorts.

Supported employment program evaluation: evaluating degree of implementation and selected outcomes.

The relation between the degree to which adult service agencies implemented supported employment and selected program outcomes was examined. Supported employment programs developed by adult vocational service agencies in Illinois served as the subject pool for data collection. Results indicated that clients with higher IQs received less complete support services but earned higher wages.

Overview of supported employment.

This article traces the emergence of supported employment as a result of philosophical changes in expectations for persons with disabilities, based on scientific developments that challenged traditional service-delivery models. Supported employment program characteristics also are reviewed, and the influence of applied behavior analysis is outlined. Finally, areas for future research in supported employment are discussed.

Teaching supported employees with severe mental retardation to solve problems.

Two individuals with severe mental retardation, employed by a janitorial supply company, were taught to use self-instruction in combination with multiple exemplar training to solve work-related problems. Use of the combined strategy resulted in generalization of the effects of independent variables, as well as generalization to nontrained problems. Use of the strategy is discussed in terms of promoting independent performance among supported employees.

Benefits and costs of supported employment: an analysis of the Illinois Supported Employment Project.

This investigation presents a cost-benefit analysis completed for one of 27 states implementing supported employment as a result of federal funding. Based upon the benefits and costs detailed, society realized a $0.75 return for every $1.

Reliability and validity of the vocational assessment and curriculum guide.

Test-retest reliability, internal consistency, and validity of the Vocational Assessment and Curriculum Guide (VACG) with subjects having different employment characteristics was investigated. The VACG, a behavior rating scale comprised of eight vocational and social skill domains, was designed to assist in the development of employment training programs for persons with mental retardation and other disabilities. Test-retest coefficients ranged from - .

Identification of co-worker involvement in supported employment: a review and analysis.

This article identifies the roles that co-workers have assumed in providing support to employees with handicaps. These roles included validating instructional strategies, collecting subjective evaluations, implementing training procedures, collecting social comparison information, and maintaining behavior in the context of actual employment. This review is based upon an existing research literature that has focused upon providing "support" to individuals with handicaps after they become employed.
