Ultraviolet and volatility loss of herbicides

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.     

Identification of obstacles for chronic pain patients to return to work: evaluation of a questionnaire

The Obstacles to Return-to-Work Questionnaire (ORQ) was developed and evaluated. A total of 154 patients with chronic musculoskeletal pain and prolonged work disability participated in the study. Factor analyses reduced the ORQ to 55 items grouped into 9 subscales. The subscales were named Depression, Pain intensity, Difficulties at work return, Physical workload and harmfulness, Social support at work, Worry due to sick leave, Work satisfaction, Family situation and support, and Perceived prognosis of work return. The subscales showed satisfactory reliability. In order to determine predictive validity a discriminant analysis was conducted with sick leave 9 months after assessment as the outcome. This analysis indicated that the scales Perceived prognosis of work return, Social support at work, Physical workload and harmfulness, Depression, and Pain intensity could significantly predict sick leave and correctly classified 79% of the patients. The Multidimensional Pain Inventory and the Disability Rating Index could also significantly predict sick leave in this sample and correctly classified as many patients as the ORQ. However, these questionnaires do not include any work-oriented items and they had a lower specificity than the ORQ. This study suggests that patients' perceptions and beliefs about work and returning to work may be a significant hindrance for actual recovery.     

What is a normal family? Common assumptions and current evidence

The social and applied human sciences have been built upon the assumption that the normal family consists of a first-marriage conjugal couple cohabiting with biological children. It is taken for granted that the wife should be responsible for child and domestic work, and that the husband should be the family's economic provider and ultimate authority. In the professional literature such traditional family structure is often described as normal in the sense of most common, as well as normal in the sense of well-functioning. Current psychological, sociological, anthropological and historical studies, however, do not support the assumption that the traditional nuclear family is the most natural, common, and/or healthy form of family arrangement. The idealization of the traditional nuclear family has had implications for theory, research, mental health practice, and social policy. Scientists and practitioners have been slow to recognize pathology in traditional nuclear families. Families other than traditional nuclear ones have been rendered invisible or pathologized. It is time for contemporary social and applied human sciences to recognize that the traditional nuclear family is a culturally- and historically-specific construct. It is also time for contemporary social and applied human sciences to develop an account of, and a research agenda about, families that take into consideration their variations across time, place, social class, ethnicity, and culture.

Air-borne B. subtilis enzymes in the detergent industry

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.     

In a Secular Spirit: Strategies of Clinical Pastoral Education

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.     

Hard hats vs. soft hearts: The conflict between principles and reality in child and adolescent care and treatment programs

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.     

Advancing child and youth care: A model for integrating theory and practice through connecting education,training, and the service system

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.     

The Cultural Dimension in Childhood

This article emphasizes the fact that culture surrounds and influences the young people in child and youth care programs all the time, and that child and youth care workers must become cultural mediators for the culturally undernourished when assisting youth in care. This work must add to psychological pedagogics and social pedagogics a third new dimension, cultural pedagogics. Through raising and answering a series of six questions concerning culture, the author hopes to stimulate better practice and educational training in the cultural preparation of young people receiving child care services.     

Correlation between vibration-induced white finger and symptoms of upper and lower extremities in vibration syndrome

Summary The correlation was investigated between the frequency of attacks of vibration-induced white finger (VWF) and numbness or coldness of the fingers and legs in patients with vibration syndrome. Some 1687 patients with vibration syndrome were examined and of these 342 chain-saw operators and 277 rock-drill operators had no disease other than vibration snydrome. Then subjects were matched by age and period of treatment within three years. In the last analysis, 20 in the VWF almost everyday group or in the never group, and 40 in the occasionally group were selected from the chain-saw operators, and from the rock-drill operators 32 in the VWF everyday or the never group and 64 in the occasionally group. The present study showed that, with the frequency of VWF attacks, patients had a higher prevalence of coldness not only in the fingers but also in the legs. These findings suggest a correlation between the severity of circulatory disturbances of the upper extremities and that of the lower ones in patients with vibration syndrome. Further studies on circulatory disturbances in the leg are required.     

Percutaneous absorption of N,N-dimethylformamide in humans

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.     

Assessment of occupational exposure to 4,4′-methylene-bis-(2-chloroaniline) “MOCA” by a new sensitive method for biological monitoring

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.     

Transsexual healing: Medicaid funding of sex reassignment surgery

Federal requirements for state Medicaid programs are surveyed, and case law regarding Medicaid funding of sex reassignment surgery is reviewed. States have attempted to exclude sex reassignment surgery (SRS) from Medicaid coverage on various bases, concluding, for example, that the procedure constituted cosmetic surgery. Judicial scrutiny of such exclusions has usually resulted in the state action being found violative of the federal Medicaid statute and accompanying regulations. In those cases upholding the state exclusion, the primary judicial obstacle to funding has been a determination that SRS is not medically necessary or is experimental. The author explores the recent scientific literature concerning long-term outcomes following SRS and concludes that the procedure, for purposes of Medicaid funding, is neither unnecessary nor experimental, and that the categorical exclusion of SRS from Medicaid coverage is therefore inappropriate. The author recommends case-specific determinations of eligibility for Medicaid funding, utilizing the standards of care promulgated by The Harry Benjamin International Gender Dysphoria Association.     

Mutagenicity of 4,4′-methylene-bis-(2-chloroaniline) “MOCA” and its N-acetyl derivatives in S. typhimurium

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.     

Media reviews

Of the three films reviewed in this issue, only the first, All Women Have Periods, deals with both areas of sexuality and disability. The second film, A Masturbatory Story, deals with sexuality but not disability. The third film, A Different Approach, deals with disability but not sexuality. The reason I have included the last two films are that A Masturbatory Story is one of the best, most permission giving films I have seen on the subject of masturbation and A Different Approach while focusing on employment of the disabled, is one of the most entertaining and effective films I have seen dealing with attitudes.     

Assertive/leveling communication and empathy in adolescent drug abuse prevention

This paper presents the feelings reported by 5th, 6th, 7th and 8th graders when role playing situations in which they wanted to say no to alcohol/drugs or to talk to a friend who was using. These role plays were part of SAY IT STRAIGHT (SIS) training, which was described in the preceding paper. Youngsters described themselves as feeling good and having high self-respect/esteem only when they said no in an assertive/leveling way. Only youngsters toward whom an assertive/leveling no was addressed described themselves as surprised/shocked and respectful of the person who was saying no. Finally, youngsters reported that the most effective way to convince a friend to quit using and/or get help was to express caring and friendship, and to touch the friend rather than being aggressive/blaming, irrelevant or super-reasonable. This feedback from youngsters opens conceptual issues relevant to some assertiveness training and drug abuse prevention programs.The authors thank Kevin Miller and Antoinette Bradley for their help on the project.This research was supported in part by the Oklahoma Department of Mental Health, Contract # N200073.     

“In vitro” measurements of spontaneous smooth muscle contractions: A screening method for “invivo” exposure

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.     

Financial “Rules” for Child and Youth Care Managers

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.     

Aging and immigration: Who are the elderly?

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.     

Mother,father, sister,friend: Metaphor and the craft of child care

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.
