Class Activist Lens for Teaching about Poverty
The mission of social work is to serve the poor and oppressed and engage in social reform. This article proposes a conceptual framework, and teaching and practice strategies to equip students to understand poverty from a class perspective. The action component is to politicize practice and become allies with the poor in resisting injustice and promoting their social and economic development

Swine embryo culture and transfer for export to England
A major threat to swine enterprises is the possible introduction of disease when new breeding animals are purchased and introduced. So, methods of introducing new genetic material while minimizing the potential for introducing disease are needed. Transfer of embryos from a donor sow in another herd or country would minimize disease risks. Already used to introduce new breeding stock into Specific Pathogen Free herds and other closed herds, embryos now are placed in the recipient gilt’s or sow1s uterus within a few hours after their recovery from the donor. That method prevents export and limits application of swine embryo transfer in this country, so we evaluated the feasibility of using an in vitro culture system to store embryos between donor sows and recipient females.; Swine Day, Manhattan, KS, November 8, 197
Environmental aspects of tensile membrane enclosed spaces
Buildings enclosed by fabric membranes are very sensitive to changes in environmental conditions as a result of their low mass and low thermal insulation values. Development in material technology and the understanding of the structural behaviour of tensile membrane structures along with the vast progress in computer formfinding software, has made it possible for structural design of tensile membrane structures to be approached with almost total confidence. On the contrary, understanding of the environmental behaviour in the spaces enclosed by fabric membrane and their thermal performance is still in its infancy, which to some extent has hindered their wide acceptance by the building industry. The environmental behaviour of tensile membrane structures is outlined and the possible use of the fabric’s topology and geometry particularly to enhance ventilation rates and airflow velocities within the enclosed space is discussed. A need for further research in this area is identified in order to fully realise the potential benefits offered by these structures
Does the Risk of Childhood Diabetes Mellitus Require Revision of the Guideline Values for Nitrate in Drinking Water?
Does the risk of childhood diabetes mellitus require revision of the guideline values for nitrate in drinking water?
In recent years, several studies have addressed a possible relationship between nitrate exposure and childhood type 1 insulin-dependent diabetes mellitus. The present ecologic study describes a possible relation between the incidence of type 1 diabetes and nitrate levels in drinking water in The Netherlands, and evaluates whether the World Health Organization and the European Commission standard for nitrate in drinking water (50 mg/L) is adequate to prevent risk of this disease. During 1993-1995 in The Netherlands, 1,104 cases of type 1 diabetes were diagnosed in children 0-14 years of age. We were able to use 1,064 of these cases in a total of 2,829,020 children in this analysis. We classified mean nitrate levels in drinking water in 3,932 postal code areas in The Netherlands in 1991-1995 into two exposure categories. One category was based on equal numbers of children exposed to different nitrate levels (0.25-2.08, 2.10-6.42, and 6.44-41.19 mg/L nitrate); the other was based on cut-off values of 10 and 25 mg/L nitrate. We determined standardized incidence ratios (SIRs) for type 1 diabetes in subgroups of the 2,829,020 children with respect to both nitrate exposure categories, sex, and age and as compared in univariate analysis using the chi-square test for trend. We compared the incidence rate ratios (IRRs) by multivariate analysis in a Poisson regression model. We found an effect of increasing age of the children on incidence of type 1 diabetes, but we did not find an effect of sex or of nitrate concentration in drinking water using the two exposure categories. For nitrate levels > 25 mg/L, an increased SIR and an increased IRR of 1.46 were observed; however, this increase was not statistically significant, probably because of the small number of cases (15 of 1,064). We concluded that there is no convincing evidence that nitrate in drinking water at current exposure levels is a risk factor for childhood type 1 diabetes mellitus in The Netherlands, although a threshold value > 25 mg/L for the occurrence of this disease can not be excluded
Final height in girls with turner syndrome after long-term growth hormone treatment in three dosages and low dose estrogens
Although GH treatment for short stature in Turner syndrome is an accepted
treatment in many countries, which GH dosage to use and which age to start
puberty induction are issues of debate. This study shows final height (FH)
in 60 girls with Turner syndrome treated in a randomized dose-response
trial, combining GH treatment with low dose estrogens at a relatively
young age. Girls were randomly assigned to group A (4 IU/m(2).d;
approximately 0.045 mg/kg/d), group B (first year, 4 IU/m(2).d; thereafter
6 IU/m(2).d), or group C (first year, 4 IU/m(2).d; second year, 6
IU/m(2).d; thereafter, 8 IU/m(2).d). After a minimum of 4 yr of GH
treatment, at a mean age of 12.7 +/- 0.7 yr, low dose micronized
17beta-estradiol was given orally. After a mean duration of GH treatment
of 8.6 +/- 1.9 yr, FH was reached at a mean age of 15.8 +/- 0.9 yr. FH,
expressed in centimeters or SD score, was 157.6 +/- 6.5 or -1.6 +/- 1.0 in
group A, 162.9 +/- 6.1 or -0.7 +/- 1.0 in group B, and 163.6 +/- 6.0 or
-0.6 +/- 1.0 in group C. The difference in FH in centimeters, corrected
for height SD score and age at start of treatment, was significant between
groups A and B [regression coefficient, 4.1; 95% confidence interval (CI),
1.4, 6.9; P < 0.01], and groups A and C (coefficient, 5.0; 95% CI, 2.3,
7.7; P < 0.001), but not between groups B and C (coefficient, 0.9; 95% CI,
-1.8, 3.6). Fifty of the 60 girls (83%) had reached a normal FH (FH SD
score, more than -2). After starting estrogen treatment, the decrease in
height velocity (HV) changed significantly to a stable HV, without
affecting bone maturation (change in bone age/change in chronological
age). The following variables contributed significantly to predicting FH
SD score: GH dose, height SD score (ref. normal girls), chronological age
at start of treatment, and HV in the first year of GH treatment. GH
treatment was well tolerated. In conclusion, GH treatment leads to a
normalization of FH in most girls, even when puberty is induced at a
normal pubertal age. The optimal GH dosage depends on height and age at
the start of treatment and first year HV
Collective Power to Create Political Change: Increasing the Political Efficacy and Engagement of Social Workers
Because social workers are called to challenge social injustices and create systemic change to support the well-being of individuals and communities, it is essential that social workers develop political efficacy: belief that the political system can work and they can influence the system. This study explored the impact of an intensive political social work curriculum on political efficacy and planned political engagement among social work students and practitioners. The findings suggest this model of delivering a political social work curriculum effectively increases internal, external, and overall political efficacy, and that increasing political efficacy has promise for increasing future political engagement
Static Magnetic Field Therapy: A Critical Review of Treatment Parameters
Static magnetic field (SMF) therapy, applied via a permanent magnet attached to the skin, is used by people worldwide for self-care. Despite a lack of established SMF dosage and treatment regimens, multiple studies are conducted to evaluate SMF therapy effectiveness. Our objectives in conducting this review are to:(i) summarize SMF research conducted in humans; (ii) critically evaluate reporting quality of SMF dosages and treatment parameters and (iii) propose a set of criteria for reporting SMF treatment parameters in future clinical trials. We searched 27 electronic databases and reference lists. Only English language human studies were included. Excluded were studies of electromagnetic fields, transcranial magnetic stimulation, magnets placed on acupuncture points, animal studies, abstracts, posters and editorials. Data were extracted on clinical indication, study design and 10 essential SMF parameters. Three reviewers assessed quality of reporting and calculated a quality assessment score for each of the 10 treatment parameters. Fifty-six studies were reviewed, 42 conducted in patient populations and 14 in healthy volunteers. The SMF treatment parameters most often and most completely described were site of application, magnet support device and frequency and duration of application. Least often and least completely described were characteristics of the SMF: magnet dimensions, measured field strength and estimated distance of the magnet from the target tissue. Thirty-four (61%) of studies failed to provide enough detail about SMF dosage to permit protocol replication by other investigators. Our findings highlight the need to optimize SMF dosing parameters for individual clinical conditions before proceeding to a full-scale clinical trial
