Implications of mainstream classrooms for adolescents with spina bifida.

This study examined the social and academic implications of mainstream, mainstream and special (combined) or special-class education for 31 adolescents with spina bifida, and for their primary caretakers. The Peabody Picture Vocabulary Test and the UCLA Loneliness Scale (adolescents) and the Personality Inventory for Children (caretakers) were administered. Adolescents in mainstream classes had the most normal scores for academic and social skills, those in combined classes had intermediate scores and those in special classes had the lowest scores. Paradoxically, adolescents in combined classes reported the least loneliness. This study suggests that even among students with relatively good social skills, mainstream placement is associated with greater subjective experience of loneliness than is combined placement.

Academic behavior and grades of mainstreamed students with mild disabilities.

This study examined the relationship between the classroom behaviors and final grades of mainstreamed students with mild disabilities in three urban schools in Grades 3-9. Significant correlations were found for all academic behaviors except attendance and homework at the elementary level and written work at the junior high level. In addition, significant differences in reading scores were found between mainstreamed and regular elementary school students. Findings indicate that mainstreamed students with mild disabilities may participate in academic lessons as well or nearly as well as their peers without disabilities.

The work of specialist nurses in the mainstreaming of germline genomic testing in cancer: an investigation.

BACKGROUND: Specialist nurses are increasingly working in the mainstreaming of germline genomic testing in cancer. AIMS: The study aimed to investigate the work of specialist nurses in the mainstreaming of germline genomic testing in cancer, with a focus on Lynch syndrome, and to consider the future of genomics in nursing. METHODS: Semi-structured interviews were conducted with a purposive sample of 12 specialist nurses and three genetic counsellors, and thematic analysis was carried out. FINDINGS: Prominent themes arising from the data were: the capability and capacity of specialty-based clinical nurse specialists, for whom genomics is an added part of their wider role, to deliver genomic testing; and whether these specialty-based nurses or specialist genomic nurses, who work only in genomics, are best placed to deliver genomic testing. CONCLUSION: When planning service provision in the mainstreaming of genetic testing, the capacity and capability of specialty-based clinical nurse specialists should be considered alongside the possible need for specialist genomic nurses.

Social acceptance of mentally retarded children in regular schools in relation to years mainstreamed.

This study examined whether the social status of mainstreamed retarded children among their nonretarded peers improved as a consequence of extended contact. A sociometric questionnaire was administered to the nonretarded classmates of two groups of retarded children mainstreamed for an average of 1.7 yr. and 4 yr., respectively. Social acceptance of retarded children was low relative to their nonretarded peers. However, in contrast with previous research, retarded children did not receive higher social rejection ratings. Acceptance and rejection measures did not indicate any improvement in social status of the retarded children as a result of an extended period of mainstreaming.

Comparative studies on the genotoxic activity of mainstream smoke condensate from cigarettes which burn or only heat tobacco.

The in vitro genotoxic activity of mainstream cigarette smoke condensate (CSC) from cigarettes which heat but do not burn tobacco was compared to that of CSC from cigarettes which burn tobacco. CSCs from five cigarettes were compared. Three of the cigarettes [the Kentucky reference research cigarette (1R4F), a commercially available ultra-low tar brand (ULT) and a commercially available ultra-low tar menthol brand (ULT-menthol]) burn tobacco while two of the cigarettes [a regular (TEST) and a menthol (TEST-menthol]) heat tobacco. CSC from all cigarettes were collected by identical standard techniques, which involved collecting mainstream smoke particulate matter on Cambridge filter pads under FTC smoking conditions. The pads were extracted with DMSO, and the CSCs obtained [10 mg total particulate matter (TPM)/ml DMSO] were evaluated at identical concentrations in an in vitro genetic toxicology test battery. CSCs from 1R4F, ULT, and ULT-menthol cigarettes were mutagenic in Ames bacterial strains TA98, TA100, TA1537, and TA1538 in the presence of metabolic activation (S9 from Aroclor-induced rat liver) but negative in strain TA1535. In the absence of metabolic activation, 1R4F, ULT, and ULT-menthol CSCs were not mutagenic except for a weak response in strain TA1537 for the 1R4F and ULT CSCs. TEST and TEST-menthol CSCs were nonmutagenic in all five bacterial strains, both with and without metabolic activation. CSCs from 1R4F, ULT, and ULT-menthol cigarettes were positive in the CHO-chromosomal aberration assay and in the CHO--sister chromatid exchange assay both with and without metabolic activation while TEST and TEST-menthol CSCs were negative in both assays, either with or without metabolic activation. CSCs from 1R4F, ULT, and ULT-menthol cigarettes were weakly positive in inducing DNA repair in cultured rat hepatocytes while TEST and TEST-menthol CSCs were negative in this assay. All five CSCs were nonmutagenic in the CHO-HGPRT assay both with and without metabolic activation. CSCs from the 1R4F, ULT, and ULT-menthol cigarettes were cytotoxic in the CHO-HGPRT assay, both with and without metabolic activation, while TEST and TEST-menthol CSCs were not cytotoxic under either condition. These results demonstrate that mainstream CSCs from the TEST and TEST-menthol cigarettes are neither genotoxic nor cytotoxic under conditions where CSCs from 1R4F, ULT, and ULT-menthol cigarettes are genotoxic and/or cytotoxic in a concentration-dependent manner.

Quantification of phencyclidine in mainstream smoke and identification of phenylcyclohex-1-ene as pyrolysis product.

Parsley cigarettes containing [3H]phencyclidine were machine smoked, and the mainstream smoke was trapped in glass wool filters. Radioactivity was extracted from these filters with chloroform. The average recoveries of radioactivity were 76, 85, 70, and 69% for cigarettes containing 3, 10, 30, and 50 mg of [3H]phencyclidine hydrochloride, respectively. TLC and GLC-mass spectrometry were employed to identify and quantify compounds in the filter extracts. Approximately one-half of the recovered radioactivity represented a pyrolysis product, phenylcyclohex-1-ene. Formation of this product involved loss of piperidine from phencyclidine. Piperidine, which was not radiolabeled, also may appear in smoke intact. The remainder of the radiolabeled material represented unchanged phencyclidine. Therefore, the percentage of [3H]phencyclidine delivered was approximately 40% of the amount smoked. This result was independent of puff frequency and quantity of phencyclidine hydrochloride smoked over the range tested. The [3H]phencyclidine delivery was compared to the quantities of [3H]-delta 9-tetrahydrocannabinol and [3H]nicotine delivered in mainstream smoke. The recovery of unchanged [3H]-delta 9-tetrahydrocannabinol from placebo marijuana cigarettes injected with a solution containing 3 mg of delta 9-tetrahydrocannabinol was 60%. Tobacco cigarettes injected with [3H]nicotine yielded 70% unchanged nicotine in mainstream smoke.

Mainstreaming psychiatry: some personal commentary.

The psychiatric education establishment is depicted as zealously searching for a set of educational principles that will allow maximum bandwagonry, maximum fundability. "Medical mainstream" is the current catch phrase selected for discussion. The contention of the author is that--instead-sound bio-social principles, easily available from child psychiatry as a field, would provide a dynamic substructure that would not be voguish and evanescent. Far from pursuing the medical mainstream, psychiatry might be more secure as an academic discipline were it to adopt an evangelical, illuminating attitude toward other medical specialties. In short, the proposal is made that general psychiatry and its fellow medical specialities ought to be brought into the child psychiatry mainstream. What child psychiatry could give to medicine and to general psychiatry is considered under these headings: a developmental perspective, a behavioral science sophistication, a medical foundation and lifestyle ("Aesculapian authority"), a humanistic attitude, and a stance of patient advocacy.

Reentry: a study of the movement of young drug users toward mainstream society.

In the middle 1960s hundreds of thousands of young people dramatically left American mainstream society to join the hippie movement. Almost ten years after the height of the hippie phenomenon, there has been little longitudinal investigation of the predictions by social scientists that these young people would be lost from future mainstream involvement. In the late 1960s, through a study of young drug users in the Haight-Ashbury neighborhood of San Francisco, my colleagues and I began to assess the degree of movement taken by hippie drug users toward mainstream society. This research focused on the differential outcome of three groups of young drug users, approximately two and a half years after they were initially studied.

Electron-spin resonance study of mainstream and sidestream cigarette smoke: nature of the free radicals in gas-phase smoke and in cigarette tar.

Radicals in the gas phase of both mainstream and sidestream cigarette smoke have been studied using electron-spin resonance ESR spin-trapping techniques with alpha-phenyl-N-tert-butyl nitrone (PBN) as the spin trap. The principal radicals we trap appear to be alkoxyl radicals. Mainstream and sidestream gas-phase smoke each have about the same concentration of radicals, about 1 X 10(16) radicals per cigarette (or 5 X 10(14) per puff). These radicals are reactive, yet they appear to be remarkably long-lived: they are still spin trapped from gas-phase smoke after more than 5 min. We propose that a steady-state concentration of reactive radicals exists in gas phase cigarette smoke. We suggest that this steady state is produced by the slow oxidation of nitric oxide (present in high concentrations in smoke and relatively unreactive) to the more reactive nitrogen dioxide, followed by the reaction of nitrogen dioxide with reactive organic molecules in smoke (such as olefins and dienes). Preliminary experiments reported here support this hypothesis. Tar from both mainstream and sidestream smoke contains persistent free radicals that exhibit broad, single-line ESR spectra with g values of 2.003. The tar radical can be extracted into tert-butylbenzene and other organic solvents, and we have applied a variety of fractionation procedures to these solutions. Most of the radicals occur in the fractions that contain the phenolic tobacco leaf pigments. Treatment of alcoholic solutions of tar with base generates a new group of radicals that appear to be semiquinone radicals derived from the oxidation of the phenolic and polyphenolic species in tar.

Effect of sidestream and mainstream smoke exposure on in vitro interferon-alpha/beta production by L-929 cells.

A peristaltic pump smoking machine that allows simultaneous generation of mainstream (active) and sidestream (passive) smoke from a cigarette was used to expose cultures of murine L-929 cells, a potent producer of interferon, to smoke. The cigarette used was the University of Kentucky 2R1 reference cigarette. The dosages of smoke used for exposure were the highest doses possible that generated a minimum toxic effect, and they were serially diluted to lower doses. Dosages were determined by the number of smoke puffs generated, the volume of smoke puffs generated, and the total particulate matter deposited on Cambridge filters in the smoke machine. Viability of exposed cells was equivalent to control cell cultures. Interferon-alpha/beta was induced by addition of polyriboinosinic-polyribocytidylic acid to the cells. Interferon production was substantially reduced in viable cells exposed to mainstream or sidestream smoke. Aging of smoke by delaying time of exposure of the cells to the smoke, or filtration of smoke through activated charcoal substantially decreased the alteration of interferon production by smoke exposure. These results suggest that actual exposure of cells to mainstream or sidestream smoke can inhibit in vitro interferon-alpha/beta induction, but the cells can be protected from these effects by smoke manipulation.

Medicaid and the Mainstream: Reassessment in the Context of the Taxpayer Revolt.

California's Medicaid program-Medi-Cal-attempted to implement the ideal of mainstream medical care for the poor by giving program beneficiaries a "credit card" for use in the private health care marketplace. This exposed the program to the perverse economic incentives of the fee-for-service, costplus health care system, and contributed to a high rate of increase in program costs. Attempts to control costs have been equally perverse, resulting in low payment rates, the second-guessing of physician professional judgments, the probing of medical and fiscal records, and the use of computerized surveillance systems. Attempts to shift to the use of more efficient delivery systems have had small success. Attempts to attain cost containment through restructuring the Medi-Cal program have been rejected in the name of the mainstream ideal. Costs have continued to escalate, with annual increases as high as 20 percent in some years. Medi-Cal now costs $4 billion per year, the largest single program in California state government. The taxpayer revolt in California is creating a fiscal crisis that will force rethinking of the premises of publicly funded health care for the poor, and a restructuring of strategies for reaching that objective. In the short run, it appears that the issue may not be whether the indigent will have access to mainstream medical care, but whether they will have access to any medical care. In the longer run, the crisis should represent an opportunity for building a system of health care that can serve the financially disadvantaged at a cost tolerable to our society.

Mainstreaming: fulfilling the promise?

Four assumptions that propelled the movement away from self-contained classes for EMR children and towards mainstreaming were presented. Available data were provided for each assumption that indicated the extent to which the initial assumption has been realized. Overall, the data did not indicate major improvement in the caliber of education provided to EMR children as a consequence of the mainstreaming movement. The limitations of present conceptions of mainstreaming were cited as was the possibility of a need to redefine the concept of least restrictive environment.

Peer preferences of at-risk and normally developing children in a preschool mainstream classroom.

Social interactions and peer preferences in a preschool mainstream classroom containing normally developing and at-risk children were studied using the ethological method of direct observation. Data on social play and on gaze orientation indicated that normally developing children and at-risk children interacted primarily with children from the same group (other normally developing and at-risk children, respectively). Data on selection on game partner and on preference of seat neighbor, however, revealed peer preference by normally developing children only. The findings were discussed as having theoretical implications for using direct observation vs. the more traditional sociometric methods for studying social adaptation in the mainstream classroom and as having practical implications for mainstreaming at risk-preschoolers.

The peer relations of mildly delayed and nonhandicapped preschool children in mainstreamed playgroups.

Previously unacquainted groups of normally developing and mildly developmentally delayed preschool-age boys (N = 64) were brought together to form a series of 8 mainstreamed playgroups. Each playgroup consisted of 3 normally developing 3-year-olds, 3 normally developing 4-year-olds, and 2 mildly developmentally delayed 4-year-olds. The delayed children were matched with the normally developing older group for chronological age and with the normally developing younger group for developmental level. Each playgroup operated 5 days per week for 2 hours per day for a 4-week period. During that time, the peer-related social and play interactions of each child were videotaped, and peer sociometric ratings were obtained at the completion of each playgroup. Analyses of social participation and individual social behavior measures revealed that the analogue playgroup setting was appropriate for evaluating peer interactions, as expected developmental patterns emerged despite the presence of children heterogeneous with respect to chronological age and developmental status. The existence of a deficit in peer-related social interactions for mildly delayed children was supported in this investigation--a deficit that could not be attributed to reputational factors, the unavailability of responsive peers, inadequate matching procedures, unusual sample characteristics, or similar factors. Selected observational measures, peer preference patterns during free play, and peer sociometric ratings also indicated that the delayed children were perceived to be less competent and of lower social status. However, despite their relative isolation, important developmental opportunities were available for mildly delayed children in the mainstreamed playgroups. Possible processes responsible for these outcomes were discussed.

Mainstreaming during the early childhood years.

Issues surrounding the implementation of the integration imperative during infancy and early childhood present formidable challenges to education and community providers. Key among these issues is how professionals provide high-quality services to young children with disabilities in mainstream environments. This article explores current issues related to integration and reexamines the concept of "best practices" as it applies to mainstreaming during the early childhood years. The author recommends an integrated set of indicators for high-quality programs and describes an outcomes-based process for making administrative and pedagogical decisions.

Mainstreaming and postsecondary educational and employment status of a rubella cohort.

The postsecondary education and work status of 46 rubella deaf young adults was described and evaluated as an outcome of ethnicity, socioeconomic status, preschool attendance, early parent involvement, and degree of prior mainstreaming. With regard to postsecondary education attendance, 24 had two or more years, 11 had one year or less, and 11 had none. At time of interview, 19 were still attending school, 22 were working and five were neither working nor attending an educational program. Ethnic minority young adults were underrepresented in the group with two or more years of postsecondary education, and overrepresented in the group neither working nor in school at time of interview. Prior mainstreaming was a determinant of postsecondary education attendance over and above the effects of demographic and background characteristics. Implications of these findings are discussed.

Attitudes toward handicapped peers of mainstreamed and nonmainstreamed children in physical education.

The influence of contact (mainstreamed and nonmainstreamed) and sex on attitudes of fifth- and sixth-grade students toward handicapped children was examined. 143 mainstreamed students attended an integrated school, whereas 86 nonmainstreamed students had no handicapped children in their school. Mean responses to the Children's Attitudes Toward Handicapped Scale were subjected to a 2 x 2 analysis of variance which indicated no significant differences by contact or sex. Chi 2 analysis of individual items indicated some significant differences, favoring contact, on items "are fun" and "are interesting".

Success of children with cochlear implants in mainstream educational settings.

The availability of cochlear implant technology has made mainstreaming a more reachable social and academic goal for profoundly deaf children. Traditionally, the profoundly deaf child has required more self-contained education. It has been the hard-of-hearing child who reached the mainstream education classroom during the elementary years. Cochlear implant recipients, implanted early and receiving appropriate educational services that maximize learning across all domains, have shown a significant trend toward moving from a more self-contained to a less restrictive educational environment. Children with implants are making these transitions earlier than the larger majority of profoundly deaf children using traditional amplification.
