The appropriateness of measuring femininity in homosexual males by means of the usual masculinity-femininity tests is questioned. It is felt that what was called by earlier observers femininity or effeminacy in males was mainly or solely feminine gender identity (F.G.I.), whereas the masculinity-femininity tests currently used in measuring femininity with males embrace a wider area of differences between males and females than that of gender identity proper. An attempt was made to arrive at a more appropriate scale by first assembling a nucleus of F.G.I. items of high clinical face validity which later could be extended by adding items strongly correlated with this nucleus. The degree of F.G.I. was assessed by means of this scale in transsexual and nontranssexual androphiles (homosexual males who erotically prefer mature partners) and heterosexual control subjects. Results showed that transsexual and heterosexual males were discriminated by F.G.I. scores without any overlap, while nontranssexual androphiles' scores overlapped heavily with those of the controls and only slightly with those of the transsexual males.This study was supported by a grant from the Clarke Institute of Psychiatry Research Fund.  相似文献

Emergency room (ER) utilization and hospitalization were studied as indicators of the impact of improvements in pediatric primary care services in an Israeli development town, Ofakim, population 12,000. One of the two pediatric services was upgraded in 1976 through the introduction of pediatric faculty, integration of preventive and curative services and conversion of the medical records to a problem-oriented format ( experimental clinic B ). The primary care system remained unchanged in the second clinic ( traditional clinic A ). During 1980, ER utilization by the B clinic population was 9.3/100 compared with 17.6/100 for the A clinic population. Fifty two percent of the B clinic population patients reaching the ER were hospitalized compared with 25% of A clinic patients.The lower ER utilization rate represents a significant saving for the health services, and educational interventions are suggested from the study. Analysis of ER utilization data seems to offer useful information for overall planning and monitoring of ambulatory services for a community.Corresponding author.  相似文献

Herbicide 2,4-D formulated as a urea-type polymer was readily destroyed by long-wave uv (356-nm) irradiation, whereas conventional 2,4-D was more resistant. The opposite relationship was noted for polymeric and conventional formulations of dicamba. Polymerized 2,4-D was more resistant to thermal degradation (60°C) than non-polymerized formulations. Ultraviolet degradation of polymerized 2,4-D was eliminated by the incorporation of RYLEX-H and UVINUL D-50, industrial uv absorbers. Exposure of polymeric dicamba to 60°C heat, followed by trapping of the volatile component, indicated that 21 percent was lost by thermal degradation and 46.6 percent by volatilization. Comparable values for non-polymerized dicamba were 37.9 and 60.1 percent.  相似文献

The levels of the health-related quality of life (HR-QoL) were analyzed in hereditary hemorrhagic telangiectasia (HHT) patients. The Short Form-36 Health Survey (SF-36) was administered to 50 HHT patients and scores were compared to a cohort of 2301 normal subjects. Clinical variables were patient age, illness duration, number of epistaxis episodes in the previous year and hemoglobin levels. Physical functioning, physical role limitations, bodily pain, social functioning, emotional role limitations and the physical component scores were lower among females. In multivariable analyses increasing age was related to lower physical functioning (P<0.04), physical role limitations (P<0.008), bodily pain (P<0.05) and emotional role limitations (P<0.01), while higher hemoglobin levels improved physical functioning(€P<0.03). The number of epistaxis episodes was negatively associated with physical role limitations (€P<0.009), vitality (P<0.002), social functioning (P<0.001), physical component summary (€P<0.001) and bodily pain (P<0.01). Illness duration was negatively related to the mental component summary (P<0.004). HHT patients had a lower HR-QoL with respect to normal controls in all domains except for bodily pain. Females had lower scores for several domains. Epistaxis was the most important clinical variable.  相似文献

The Clinical Pastoral Education (CPE) model forthe provision of spiritual care represents theemergence of a secularized professionalpractice from a religiously-based theologicalpractice of chaplaincy. The transformation ofhospital chaplaincy into spiritual careservices is one means by which religioushealthcare ministry negotiates modernity, inthe particular forms of the secular realm ofbiomedicine and the pluralism of thecontemporary United States healthcaremarketplace. Spiritual is a labelstrategically deployed to extend the realm ofrelevance to any patient's belief system,regardless of his or her religious affiliation.Theological language is recast as a tool forconceptualizing the spiritual lens. Suchmoves transform chaplaincy from a peripheralservice, applicable only to the few religiouspatients, into an integral element of patientcare for all. Such a secularized professionalpractice is necessary to demonstrate therelevance and utility of spiritual care for allhospital patients in an era of cost-containmentpriorities and managed care economics.  相似文献

Summary A new specific and sensitive method for the urinary determination of 4,4-methylene-bis-(2-chloroaniline) (MOCA), a known carcinogen in rats, mice and dogs, has been developed. After a brief study on rats to determine some peculiarities in MOCA urinary excretion, this method was used to assess occupational exposure in French industrial firms. Both the manufacture of MOCA and its use as a curing agent in the production of polyurethane elastomers were surveyed. MOCA excretion levels were distributed from non-detectable (<0.5 g/l) up to 1600 g/l. Concentrations of N-acetyl metabolites, when present, were largely lower than MOCA levels. The results seemed to reflect workers' overall exposure fairly. Preventive measures following analytical determinations often led to an obvious lowering of excretion levels.  相似文献

Summary 4,4-methylene-bis-(2-chloroaniline) (MOCA) and two identified urinary N-acetyl and N,N-diacetyl derivatives were tested in a Salmonella/mammalian microsome assay. No mutagenic activity was observed without rat liver S9 mix activation. In the presence of rat liver S9 mix, the chemicals were mutagens, but the mutagenicity of N-acetyl derivatives to strain TA 100 was reduced when compared to that of MOCA, and a greater amount of S9 was required to exhibit the mutagenicity of the N,N-diacetyl-MOCA. These data suggest that N-acetylation does not account for the mutagenic effectiveness of MOCA.  相似文献

Much of child care in volves quick reactions based on one's automatic pilot derived from how we were parented. This paper is about two seemingly universal automatic pilot systems—the hard hats and the soft hearts. Hard hats are behavior management and modification oriented, while soft hearts are psychodynamically and counselling oriented. Typically, the hard hats tend to have the upper hand due to the nature of our culture, and they therefore have the effect of preventing the contributions of the soft hearts from being realized. That all too frequently sets up a dominant culture and a resentful minority situation. To correct this imbalance, a value orientation from the top which emphasizes mutual respect and utilization is suggested.Grateful acknowledgement is made to Ray Peterson for his helpful suggestions in the preparation of this paper.  相似文献

Summary Air-borne dust was collected on stationary and portable filters in two factories producing biological detergents. In one factory (Factory A) the detergent base was mixed with enzyme (subtilisin) powder, and the handling of the enzyme was done without effective protection. In the other factory (Factory B) the enzyme was encapsulated in granules before mixing the with detergent base, and the production line was shielded to prevent the spread of dust.Both the amount of air-borne dust and the relative enzyme activity of the dust were greater in Factory A than in Factory B in spite of the considerably larger production of enzyme detergents in the latter factory. The workers studied in Factory A were, on the average, exposed to 5.4 GU (glycine units) per cubic millimetre in their breathing zones, and those studied in Factory B were exposed to enzyme activities about and below 1 GU/m3.Based on exposure measurements and medical examination of the exposed workers, a time-weighted hygienic limit value for subtilisins of 1 GU/m3 is proposed.  相似文献

Percutaneous absorption of N,N-dimethylformamide in humans   总被引:3,自引:0,他引:3  
Summary Skin penetration fo N,N-dimethylformamide (DMF) liquid or vapour was studied in volunteers. Exposure to liquid DMF was performed in two ways: in a dipping experiment, one hand was dipped up to the wrist in DMF for 2–20 min, while in a patch experiment, 2 mmol DMF was applied to the skin and allowed to be absorbed completely. The period of exposure to DMF vapour (50 mg · m–3) was 4 h. The DMF metabolites N-hydroxymethyl-N-methylformamide (MF), N-hydroxymethylformamide (F), and N-acetyl-S-(N-methylcarbamoyl)cysteine (AMCC) were monitored in the urine. Liquid DMF was absorbed through the skin at a rate of 9.4 mg · cm–2 · h–1. Percutaneous absorption of DMF vapour depended strongly on ambient temperature and humidity and accounted for 13%–36% of totally excreted MF. The results suggest that skin absorption of liquid DMF is likely to contribute to occupational exposure substantially more than penetration of DMF vapour. The yield of metabolites after transdermal DMF absorption was only half of that seen after pulmonary absorption. Elimination of MF and F but not that of AMCC was delayed, which supports the contention that AMCC should be used instead of MF as the most suitable biomarker of DMF in cases where percutaneous intake can occur.  相似文献

This article presents a comprehensive model for enabling connections to be made between theory and practice in the field of child and youth care, based on an analysis of current training and education in the field and a multi-step concept of theory-to-practice and practice-to-theory. The model presents a logical sequence of activities that generate and convey knowledge from two sources. One is formal empirical and research information; the other is the conceptualization of practitioners' direct experience. Both are reinforced by trainers and educators with dual connections with practice and training and education settings. The paper stresses that academic programs are a significant component of any profession, in that they are responsible for collecting and codifying emergent knowledge gathered from multiple sources.There is nothing so practical as a good theory. —Kurt Lewin (quoted in Hunt, 1987, p. 4) There is nothing so theoretical as good practice. —David Hunt (1987, p. 11)An earlier version of this paper was the winner of the 1989 Albert E. Trieschman Prize Competition, published author category, for the best original contribution to the literature of child care.  相似文献

Clinical data from two cases of male transsexualism, a child and an adult, illustrate the nature of the bisexuality typical of such patients. The first, an 8-year-old boy whose desire to be a girl is seen in his constant dressing and acting like a girl, confirms in play therapy, story telling, and drawings his fantasies of being a female. However, these fantasies are never free of the knowledge that he has a penis and a male identity as well. That this bisexuality persists into the transsexual's adulthood is exemplified in the fantasy life of the second case, a 30-year-old operated male transsexual. The memory, I was once a boy never quite fades away; no matter how successfully the passing as a woman is managed, she cannot rid herself of the secret maleness. The belief in such patients that they are fundamentally female though possessed of an anatomically normal male body will persist through adulthood, unaltered by sex change, by hormonal or surgical procedures, or by living successfully for years as a woman. This bisexuality is conscious, painful, and not assuaged by symptom formation, forgetting, or other defenses that would remove the conscious sense of having two sexes. In the child the unwanted sense of belonging to the male sex, which causes a disquieting undercurrent, can be used as the base upon which a more solid sense of masculinity can be built. Unfortunately, for the adult transsexual the balance of the two-sexed awareness cannot be tipped to a willingness to live as a man; despite treatment aimed at making them more manly, adult transsexuals retain their wish to be female—and their secret knowledge that, after all the operations and female hormones, a male part remains untouched within.Read at the Fall Meeting of the American Psychoanalytic Association, New York, December 1969.  相似文献

Summary A rapid determination of erythrocyte pyrimidine 5-nucleotidase (P5N) activity in lead workers was carried out using a high-performance liquid chromatograph (HPLC). The P5N activity had a good negative correlation with the concentration of lead in blood (PbB) ranging from 16 to 96 g/dl (r = -0.82, n = 77). Further, the P5N was compared with other biological parameters: erythrocyte -aminolevulinic acid dehydratase (ALAD) activity, erythrocyte protoporphyrin (PROTO), urinary -aminolevulinic acid (ALA) and urinary coproporphyrin (COPRO).The correlation coefficients between P5N and ALAD, log PROTO, log ALA, and log COPRO were 0.59, –0.72, –0.65, and –0.61, respectively. On the other hand, the normal value of P5N obtained from 72 healthy subjects was 11.9 ± 2.1 units; ol uridine/h/g Hb (mean ± SD), indicating that the lower limit of 95% confidence interval for normal P5N was about 8 units. When P5N was cut off at 8 units in 77 lead workers, the validity (sensitivity + specificity) for PbB 40 g/dl, PbB 60 gg/dl, erythrocyte PROTO 150 g/dl RBC, urinary ALA 6 mg/l, and urinary COPRO 150 g/l was 1.66, 1.76, 1.57, 1.68, and 1.60, respectively. From these results, it was confirmed that the erythrocyte P5N test is suitable for the biological monitoring of exposure to lead in a wide range, and its activity is useful in predicting the disturbance of porphyrin metabolism induced by lead.  相似文献

Much U.S. research in aging and the social sciences of health compares beliefs, conditions, or behaviors of racial groups. In immigration studies, social identity is most often delineated by virtue of foreign origin with respect to a host country. Thus, nationality is often the marker of difference. The present article joins two generally separate streams of research, gerontologic and immigration research in the United States. The paper considers data from several studies of seniors in Cleveland, Ohio in the 1990s; the Black and White Caregivers and the Use of Services of Black and White Elderly. These are considered not in terms of their original research goals, but rather in terms of a reflective examination of assumptions regarding the identity of the elders and caregivers that framed the two studies. The results show that racial terms conceal, not reveal, the actual ethnic and therefore, cultural, affiliations of the seniors. We suggest that because racial classification is an impediment to, rather than a facilitator of, cultural comparisons, such terms should not be used to compare, predict or explain beliefs or behaviors. The revelation of distinct, highly varied ethnic groups within asserted homogeneous racial groups has implications for immigration studies. These are discussed in the final section as relates to psychiatric and social issues.  相似文献

A series of programs to teach sex education and related skills to severely handicapped students is presented. The programs were implemented over a seven year period. Training was conducted in public school, home and community settings. The programs encompass skills in the areas of Bodily Distinctions, Reproduction and Birth Control Information, Family Life, Self Care and Social Manners and Interactions. The programs were data based and continuously have been revised and extended in response to student performance. The cooperation and support of the students' parents was considered crucial to program development and to facilitate the transfer of skills from the school to the home setting. Students who have received training in these sex education and related skill programs currently are using the skills in a variety of school, home and community settings.  相似文献

The toxicity of mercury (HgCl2), copper (CuCl2: 5 H2O), nickel (NiSO4: 6 H2O), lead (Pb(CH3COO)2: 3 H2O) and cobalt (CoCl2: 6 H2O) was studied under standardized conditions in embryos and larvae of the zebrafish,Brachydanio rerio. Exposures were started at the blastula stage (2–4 h after spawning) and the effects on hatching and survival were monitored daily for 16 days. Copper and nickel were more specific inhibitors of hatching than cobalt, lead, and mercury. Nominal no effect concentrations determined from the dose-response relationships (ZEPs, Zero Equivalent Points) for effect on hatching time were 0.05 g Cu/L, 10 g Hg/L, 20 g Pb/L, 40 g Ni/L and 3,840 g Co/L, and those for effect on survival time were 0.25 g Cu/L, 1.2 g Hg/L, 30 g Pb/L, 80 g Ni/L, and 60 g Co/L. The no effect concentrations for Ni, Hg and Pb are consistent with previously reported MATC values for sensitive species of fish. The no effect concentrations for copper are 1–2 orders of magnitude lower than previously reported values. The major reason for the latter discrepancy was considered to be the absence of organics that can complex copper ions in the reconstituted water that we used, which had a hardness of 100 mg/L (as CaCO3) and a pH of 7.5–7.7. Unexposed controls were started with embryos from different parental zebrafishes and the parental-caused variability in early embryo mortality, median hatching time and median survival time were estimated.  相似文献

Contemporary realities demand that child and youth care managers cast off their traditional avoidance of all things financial. This article offers a jargon-free list of twelve financial rules for thriving in turbulent times. Grounded in a concept of client-centered, results-based agency performance, rules include promoting an entrepreneurial spirit throughout the organization, destroying the taboo on open discussion of financial matters, slashing program development time, and spending lavishly on recruitment and universal staff training.  相似文献

Language not only reflects, but shapes our perception of the world. In child care, the perception has been shaped by imagery borrowed from the medical and behavioral-learning models. But these fail to illuminate the key feature of child care, the relationship between child and worker. The metaphors of competence and professionalism attempt to make up for the inadequacies of the other models, yet neither of these ground the abstract care in everyday experience. Developmental science provides the base for a child care perspective, and the metaphors of care need to be sensitive to this base.  相似文献

Conclusion The in vitro recording of spontaneous contractions was selected as a neuromuscular screening method for in vivo exposure to pollutants. The rate of contraction was determined by interval histogram measurements. The method was assessed for effects of age, sex, pH, Ca++ concentration, temperature, and circadian rhythm. Male rats were shown to develop a slower rate of contraction with age. The rate of contraction was temperature and pH dependent. An effect was demonstrated for in vivo exposure to Baygon and Carbaryl at a level which did not produce overt symptoms.  相似文献

Large sex differences in children's toy preferences are attributed to gender group identification and social learning. The proposal outlined in this paper is that contemporary conceptual categories of masculine or feminine toys are also influenced by evolved perceptual categories of male-preferred and female-preferred objects. Research on children exposed prenatally to atypical levels of androgens and research on typically developing infants suggest sex-dimorphic preferences exist for object features, such as movement or color/form. The evolution and neurobiology of mammalian visual processing—and recent findings on sex-dimorphic toy preferences in nonhuman primates—suggest further that an innate bias for processing object movement or color/form may contribute to behaviors with differential adaptive significance for males and females. In this way, preferences for objects such as toys may indicate a biological preparedness for a masculine or feminine gender role—one that develops more fully as early perceptual preferences are coupled with object experiences imposed by contemporary gender socialization.  相似文献
