In this article the authors report the results of a year-long investigation into the state of the low-power FM (LPFM) industry on its 10th anniversary. They question whether LPFM stations give voice to the previously voiceless as envisioned or, as some research has indicated, benefit religious communities' efforts to expand their cultural reach. Using a 2-phase study, the authors first mapped the LPFM industry using Federal Communications Commission data and public information provided by LPFM stations and their owners and operators over the Internet. The authors then conducted interviews with dozens of LPFM operators across the United States. Results indicate that large interests, in particular religious organizations, have created de facto networks that rely on outside entities for the majority of programming, thus circumventing the spirit of the original policy. 相似文献

An assessment of the extent of public involvement in the FCC's media ownership hearings in 2006–07 was conducted through an analysis of the hearings' structure, the 732 public comments made in them, and the FCC's ensuing Report & Order (R&O). In light of the rising call for pluralism, direct democracy and public involvement in policy deliberations, the results reveal that the FCC consistently hindered public participation in the hearing process it initiated and managed through limited advance notice, inconvenient timing, a hearing structure that subordinated the public to experts and stakeholders, and scarce mention of public comment in the final report. 相似文献

Mass spectrometry provides a convenient platform for the study of different protein post translational modifications from
clinical specimen. Analysis of different post translational modifications of hemoglobin like glycation and glutathionylation
can provide useful information on the disease progression and the possible outcome of therapies. In the present study, we
have addressed post translational modifications of hemoglobin like glutathionylation and glycation in relation to diabetes
and chronic renal failure. We found that both alpha and beta chains of human hemoglobin are glycated irrespective of the extent
of glycemia as evidenced by a mass increment of 162 Da. The phenomenon of glutathionylation was observed with only the beta
globin chain of hemoglobin probably due to the presence of an accessible cysteine residue indicated by a mass increment of
305 Da. Also, the extent of gltuathionylation observed in the CRF patients could correlate with the severity of the oxidative
stress owing to renal replacement therapies like dialysis and transplantation. 相似文献

To investigate reversibility of ethanol induced testicular injuries on treatment with L-ornithine-L-aspartate, male Wistar
rats were treated with ethanol (1.6g/kg b.wt/day) and L-ornithine- L-aspartate (200mg/kg b.wt/ day) for 4 weeks. L-ornithine-L-aspartate
effectively prevented the ethanol induced body and testes weight reduction; changes in testicular weight well correlated with
body weight. Drug exhibited an ability to counteract ethanol induced oxidative challenge as it effectively reduced testicular
TBARS and increased tissue ascorbic acid, GSH and activities of superoxide dismutase, catalase, GSH-Red and Se-GSH-Px. However
the drug didn’t show promising effect on inhibitory effect of ethanol on testicular D5, 3-beta and 17-beta HSD (hydroxy steroid
dehydrogenase). 相似文献

The present study deals with the evaluation of glycemic profile of aqueous extract of Cajanus cajan leaves in streptozotocin induced type 2 diabetic rats. Single oral administration of graded doses of aqueous extract of Cajanus
cajan leaves showed significant increment of 14.3 % in fasting blood glucose levels of normal rats. The sub diabetic and mild diabetic
models have also shown hyperglycemic effect from the same variable doses of the extract. The dose of 1000 mg/kg showed the
maximum rise of 17.1, 71.2 and 50.7 % in Blood glucose levels of normal, sub and mild diabetic rats respectively during glucose
tolerance test. The study of leaves was taken into consideration on the basis of earlier reported hypoglycemic activity of
Cajanus cajan seeds. However the results observed were found just opposite and therefore it may be useful in controlling hypoglycemia,
occasionally caused due to excess of insulin and other hypoglycemic drugs. 相似文献

The emergence of numerous learning style models over the past 25 years has brought increasing attention to the idea that students learn in diverse ways and that one approach to teaching does not work for every student or even most students. We have reviewed five learning style instruments (the Kolb Learning Style Indicator, the Gregorc Style Delineator, the Felder–Silverman Index of Learning Styles, the VARK Questionnaire, and the Dunn and Dunn Productivity Environmental Preference Survey) in this article in order to describe the learning style modes or dimensions measured in the instruments; find the common measures and the differences; report on research on instrument validity, reliability, and possible improvement in student performance; suggest classroom activities that work with the different student learning styles; and recommend selection of models under several conditions. We also review one additional learning style instrument, the Revised Approaches to Studying Inventory, as a complementary approach to using one or more of the first five learning style instruments. 相似文献

In view of association of diabetes mellitus and male infertility, present study was designed to investigate the functional
status of hypothalamic pituitary gonadal (HPG) axis in diabetic men. Thirty-five diabetic men (BMI 22.24±0.21) in the age
group 20–40 (30.6±4.7) years were selected. Twenty-five healthy men (BMI 23.85±0.25), in the same age group (29.5±4.8) served
as control. Blood samples were collected for hormonal and biochemical estimations. Diabetic men had significantly low serum
testosterone with low LH and FSH, hypercholesterolemia, hypertriglyceridemia, hypoalbuminemia and increased oxidative stress.
Low serum testosterone in diabetic men was accompanied by low LH and FSH; the inability of the pituitary gland to respond
appropriately to a decline in testosterone implying central effect of high serum glucose on the interaction between the nervous
and endocrine system. Nutritional deficiency, increased oxidative stress and increased aromatase activity due to excessive
body fat might have also contributed to low serum testosterone. 相似文献

ABSTRACTSeldom have comparative studies of educational assessment systems been undertaken, especially regarding their standard setting procedures. This study examines the effects of governance structures on the power relations in standard setting in the dominant school-leaving or university-entrance examinations. We present acritical analysis of the published research and policy documents, including sense-checking with senior assessment practitioners from 22 jurisdictions. The nature of standard setting systems in three cases of Ireland, the USA and India are described in detail to showcase the differences between the following three models of governance systems: nationalised, commercial market and quasi-market. The contribution of this article, then, is to describe the three models of governance systems, to classify the 22 jurisdictions using the three models, and to generate propositions inductively. Thus, the article provides aconceptual basis for extension of this work to other cases to advance the literature cumulatively by theory-building. 相似文献

The “drug novelty hypothesis” was tested directly by giving rats experience with intraperitoneal injections of ethanol on days prior to avoidance training. This preavoidance experience with ethanol was found to eliminate the prolonged extinction of avoidance responding observed after a single exposure to ethanol. It is suggested that these findings confirm the novelty hypothesis in an active avoidance situation. Possible mechanisms of the drug novelty effect were discussed. 相似文献
