The empirical relationships between standardized measures of religiosity and personality/mental health.

The aim of this study was to investigate the relationships between standardized, factor-based measures of religiosity and personality/mental health. In a sample of 471 self-identified Christian subjects, 303 females and 168 males, 79 non-psychotic psychiatric in-patients and 392 non-patients, personal extrinsicness was partially positively correlated with the BCI Obsessive score. In multiple regression analyses some of the factor-based religious orientation indices related differently to the BCI Oral, Obsessive and Hysterical Scales and the SCL-90 Global Symptom Index as dependent variables. The religious orientations explained 8.8% of the variance of the BCI Oral Score, 4.2% of the BCI Obsessive score, 3.3% of the BCI Hysterical score, and 12.3% of the SCL-90 Global Symptom Index score. Of the doctrinal belief and morality indices only with Moral conservatism was significantly related to the BCI Hysterical score, and then negatively.

Evidence for an independent syndrome of hyperactivity.

It has recently been suggested that hyperactivity and an aggressive conduct disorder cannot exist independently in children. The results of a factor analysis of the Conners Teacher Rating Scales of over 9000 children provided preliminary evidence to the contrary; a hyperactivity factor emerged as explaining the greatest proportion of the variance. Because of the large size of our data-set, it was deemed necessary to investigate the heuristic value of this finding. Using norms calculated on composite factor scores, a contingency analysis was performed to determine the proportions of children who were above a two-standard deviation criterion of deviance on all factors and combinations of factors. The use of different degrees of statistical control produced prevalence estimates comparable to those reported in the literature. These findings raise the possibility that studies reporting different prevalences of hyperactivity may, in fact, be exercising different degrees of conservatism in classification. Also, when the extent of overlap along each of our factor dimensions was examined, a group of children who appeared to be hyperactive but not conduct-disordered emerged. These findings provide evidence for an independent syndrome of hyperactivity in a sample of Canadian children.

Urostomy appliances and stoma care routines. The relation to peristomal skin complications.

The aim of the study was to describe types of appliances and stoma care routines and evaluate their relation to peristomal skin complications. Sixty-six patients with a cutaneous uretero-ileostomy were interviewed and the peristomal skin was assessed according to Classification of Peristomal Skin (CPS). The results show a conservatism regarding the types of appliance and the stoma care routines. More than half of the patients used the same product at follow-up as they were initially fitted with three to 14 years earlier. The routines adopted by the patients were often inadequate, resulting in skin complications. Continuous exposure of the skin to urine by creation of a too wide opening in the face-plate and infrequent changing of the appliance resulted in development of pseudoverrucose skin lesions.

Trend in breech delivery in Saudi Arabia.

An analysis of 2,168 consecutive singleton breech deliveries showed significant improvement in neonatal mortality and morbidity rates for babies delivered by Caesarean section (CS) compared with vaginal delivery (p less than 0.001). The CS rate was 19%. The uncorrected perinatal mortality (PNM) rate was 90.4/1,000 which was 2.5 times higher than the overall hospital PNM rate. In the vaginal delivery group the neonatal death (NND) rate of 206/1,000 among low birth-weight infants (less than 2,500 g) was significantly higher than that of 18/1,000 among babies of greater than 2,500 g (p greater than 0.001). There was no significant difference in the NND rate between these 2 birth-weight groups delivered by CS (p greater than 0.3). Social conservatism, large family size and limited neonatal care facilities were deterrents to an increase in the Caesarean section rate.

Risk communication in the real world.

Rigorous health risk assessments of site-specific projects are generally little understood by nontechnical decision makers and the public and often appear to them to obfuscate a straightforward answer to their fundamental question: "Is the project safe?" The focus on risk, usually out of context of benefits, deprives the reader of the opportunity to make a fully informed decision on the proposal. While the risk assessment tools may need to be refashioned, confidence in the analytical process can be improved, partly through more citizen involvement, as well as through more effective communication of the conservatism of the assumptions, the thoroughness of the process, and the significance of the results in comparison to other commonly accepted involuntary exposures and risks.

Risk assessment for aflatoxin: II. Implications of human epidemiology data.

A review of epidemiology literature revealed that only studies conducted in Africa and Asia included data adequate to permit quantitative assessment of the dose-response relationship between aflatoxin exposure levels and liver cancer rates. Although these studies were judged adequate, their direct use to predict risks in U.S. populations may be questioned since hepatitis B virus (HBV) infections are far more common in the studied areas than in the U.S. Recent research indicates that, if aflatoxin contributes to the development of liver cancer, it almost always does so in the presence of HBV infection. The African/Asian data do not permit us to estimate the potency of aflatoxin in the absence of HBV. Recognizing this, these data can only be used to establish upper limits for the predicted excess lifetime risk for liver cancer in the U.S. When used in conjunction with aflatoxin exposure estimates for the Southeast U.S., these data predict a liver cancer rate, due to aflatoxin alone, far above that actually observed due to all causes; this provides an indication of the conservatism of this approach. Data from the Southeast U.S. may be used to estimate an excess lifetime risk for liver cancer of 2.17 x 10(-6) x (aflatoxin intake, ng/kg/day).

Value patterns and content among families of Soviet immigrants: SYMLOG analysis.

The purpose of this qualitative study is to understand and compare two immigrant families whose children perceived their families to be well-functioning, and two families whose children perceived them to be poor-functioning. The method of analysis used for studying the values of the families is based on SYMLOG. Four families, who immigrated to Israel during the early seventies from the former USSR, and whose adolescents were born in Israel, were interviewed. The results show that in the two "well-functioning" families, there is a high degree of consensus on their values-those that they accept, as well as, those that they reject. The two "poor-functioning" families did not exhibit identical value patterns--neither in the values that they favor, nor in those that they reject. In terms of content, in the well-functioning families, there was a strong expression of two values: friendliness and the desirability of self-sacrifice in order to reach family goals. In contrast, in the poor-functioning families, the value of conservatism was salient. Finally, all four families expressed strong opposition to the values of strong individualism and nonconformity. Suggestions for family intervention are offered.

Ultrastructural variability in the locomotor cortex of the ciliated protozoa, Mytilophilus pacificae.

Mytilophilus pacificae is an endocommensal ciliate found in the mantle cavity of the Pacific Coast mussel Mytilus californianus. In this paper we report our findings on pellicular organization of this species. Transmission and scanning electron microscope examination of the somatic cortex revealed that a number of different types of kinetids, i.e. monokinetids, dikinetids, and polykinetids are found in the locomotor cortex. The type and distribution of the kinetids are described. Surprisingly, the locomotor region was found to be highly variable among individuals with respect to its kinetid distribution; each cell appears to have its own characteristic kinetid pattern. Some cells have mostly monokinetids and dikinetids in their locomotor cortex, while others may have dikinetids and polykinetids but very few monokinetids. In contrast to the locomotor region, the thigmotactic field (a region specialized for attachment) is exclusively composed of dikinetids and shows no heterogeneity. The finding of ultrastructural variability in the locomotor cortex was unexpected since, in the view of the structural conservatism hypothesis, the somatic cortex is seen as a "stable" element. These observations raise new questions with regard to cortical pattern formation in this organism.

Comparison of sequence differences in a variable 23S rRNA domain among sets of cryptic species of ciliated protozoa.

Studies were undertaken to discover the relative molecular distances separating some familiar forms of ciliated protozoa, and the genetic species they include. Sequences of 190 bases of the D2 domain of the large ribosomal nucleic acid molecule were obtained by polymerase chain reaction from protists of three distinctive groups of ciliated protozoa-Colpoda, Paramecium and Tetrahymena. Evolutionary trees were constructed for each set of sequences using the PHYLOGEN 1.0 string programs. All three groups of ciliates manifested large molecular diversity among strains difficult or impossible to distinguish morphologically. The largest single evolutionary distance within a group was the 75 differences separating Tetrahymena paravorax from the other tetrahymenids. The largest mean distance for a group was the 21.2 for the colpodids. In all the protist groups the large molecular diversity is obscured by morphological conservatism associated with constraints of ancient designs. The molecular diversity within morphotypes argues for long evolutionary coexistence of species differentiated from each other in significant physiological, ecological, or nutritional ways.

Boom or bust: future of health profession education.

The future of allied health education depends greatly on the nature of economic, social, political and health trends. It behooves educators and administrators to consider such trends as dramatic cutbacks in educational funding, revision of Medicare and Medicaid hospital reimbursement policies, establishment of diagnosis related groups (DRG), increasing technology, the wave of conservatism and the aging population. The effect of the health profession is speculative, however, knowing these trends and properly preparing, revising and reorganizing for them will keep allied health educational programs viable. This paper addresses the trends and their impact on education.

Politics and the success of school-based health centers.

School-based health centers (SBHCs) provide access to health services by bringing providers to children (and sometimes parents) and furnishing low cost services in an atmosphere of trust. While the number of SBHCs has continued to grow and some clinics have continued to expand their services, others have barely survived and some have even closed. This study investigated factors, particularly political forces, that affected the success of SBHCs. Using a national survey of clinic directors, this study assessed clinic success in terms both of longevity and service delivery. Findings indicate the factors most consistently and significantly associated with success include not only measures of "need" (school size and percent African-American enrollment or population) but of "politics" (citizen political ideology and Southern conservatism). Thus, politics matters more than previous studies suggested.

Post-insertion sensitivity with a bonded etched cast metal prosthesis. Case report.

An interesting case of post-insertion sensitivity in a patient who had an etched cast metal prosthesis (Maryland Bridge) cemented with a recently marketed resin luting agent is discussed. This case report draws attention to the fact that despite the relative conservatism and simplicity commonly associated with abutment tooth preparation for resin bonded prostheses, dentine exposure should be avoided if possible to reduce the potential for chemical irritation of the pulp by components of the resin luting system.

A sociological perspective on public support for capital punishment.

Conceptualizations of public support for the death penalty that suggest that punitiveness, desire for vengenance, authoritarianism, polital conservatism, or other characteristics generally held in low esteem by many in the academic and research communities are the primary or most significant predictors of citizen responses to this issue are challenged. It is proposed instead that fear of crime, perceptions of increasing crime rates, a belief in the efficacy of punishment as a means of deterrence, and a willingness to employ punishment as a response to criminality have a far more important causal role than has previously been recognized.

The determinants of attitudes towards social security recipients.

This study aimed to investigate the relationship between demographic variables (age, sex, education, vote and income), psychological beliefs (alienation, Protestant work ethic and Conservatism) and social security attitudes. Over 250 people from a variety of different backgrounds completed a number of standardized questionnaires. A factor analysis of the attitudes to social security scale revealed four clearly interpretable factors, which were later computed in four subscale scores. Analysis of variance showed that vote, Protestant work ethic, and Conservative beliefs most differentiated subjects' attitudes to social welfare. A canonical correlational analysis revealed three significant variates which showed age, alienation and the Protestant work ethic most closely related to social security attitudes. These results were discussed in terms of previous literature in this area and various social policy implications are considered.

The linear no-threshold debate: where do we go from here?

For the past several years, the LNT (linear no-threshold) theory has come under attack within the scientific community. Analysis of a number of epidemiological studies of the Japanese survivors of the atomic bombings and workers exposed to low level radiation suggest that the LNT philosophy is overly conservative, and low-level radiation may be less dangerous than commonly believed. Proponents of current standards argue that risk conservatism is justified because low level risks remain uncertain and it is prudent public health policy; LNT opponents maintain that regulatory compliance costs are excessive, and there is now substantial scientific information arguing against the LNT model. Regulators use the LNT theory in the standards setting process to predict numbers of cancers due to exposure to low level radiation because direct observations of radiation-induced cancers in populations exposed to low level radiation are difficult. The LNT model is simplistic and provides a conservative estimate of risk. Abandoning the LNT philosophy and relaxing regulations would have enormous economic implications. However, alternative models to predict risk at low dose are as difficult to justify as the LNT model. Perhaps exposure limits should be based on model-independent approaches. There is no requirement that exposure limits be based on any predictive model. It is prudent to base exposure limits on what is known directly about health effects of radiation exposure of human populations.

Evolution of the nucleoprotein gene of influenza A virus.

Nucleotide sequences of 24 nucleoprotein (NP) genes isolated from a wide range of hosts, geographic regions, and influenza A virus serotypes and 18 published NP gene sequences were analyzed to determine evolutionary relationships. The phylogeny of NP genes was determined by a maximum-parsimony analysis of nucleotide sequences. Phylogenetic analysis showed that NP genes have evolved into five host-specific lineages, including (i) Equine/Prague/56 (EQPR56), (ii) recent equine strains, (iii) classic swine (H1N1 swine, e.g., A/Swine/Iowa/15/30) and human strains, (iv) gull H13 viruses, and (v) avian strains (including North American, Australian, and Old World subgroups). These NP lineages match the five RNA hybridization groups identified by W. J. Bean (Virology 133:438-442, 1984). Maximum nucleotide differences among the NPs was 18.5%, but maximum amino acid differences reached only 10.8%, reflecting the conservative nature of the NP protein. Evolutionary rates varied among lineages; the human lineage showed the highest rate (2.54 nucleotide changes per year), followed by the Old World avian lineage (2.17 changes per year) and the recent equine lineage (1.22 changes per year). The per-nucleotide rates of human and avian NP gene evolution (1.62 x 10(-3) to 1.39 x 10(-3) changes per year) are lower than that reported for human NS genes (2.0 x 10(-3) changes per year; D. A. Buonagurio, S. Nakada, J. D. Parvin, M. Krystal, P. Palese, and W. M. Fitch, Science 232:980-982, 1986). Of the five NP lineages, the human lineage showed the greatest evolution at the amino acid level; over a period of 50 years, human NPs have accumulated 39 amino acid changes. In contrast, the avian lineage showed remarkable conservatism; over the same period, avian NP proteins changed by 0 to 10 amino acids. The specificity of the H13 NP in gulls and its distinct evolutionary separation from the classic avian lineage suggests that H13 NPs may have a large degree of adaptation to gulls. The presence of avian and human NPs in some swine isolates demonstrates the susceptibility of swine to different virus strains and supports the hypothesis that swine may serve as intermediates for the introduction of avian influenza virus genes into the human virus gene pool. EQPR56 is relatively distantly related to all other NP lineages, which suggests that this NP is rooted closest to the ancestor of all contemporary NPs. On the basis of estimation of evolutionary rates from nucleotide branch distances, current NP lineages are at least 100 years old, and the EQPR56 NP is much older.(ABSTRACT TRUNCATED AT 400 WORDS)

Management of foreskin problems.

One hundred consecutive cases of boys with foreskin problems referred to local paediatric surgeons in the Edinburgh area were studied. Fifty five underwent circumcision and the remainder were managed more conservatively with or without the use of local or general anaesthetic. Although sometimes avoiding general anaesthetic, the more conservative methods involved more frequent visits to the clinic, a larger number of complications, and a longer follow up period. Despite the vogue for conservatism, circumcision still has an important part to play in the management of troublesome foreskins in children.
