The law, imagery and televised campaign advertising: A legal analysis of the constitutionality of restricting external imagery in televised campaign advertising for federal office
The possible effects of external imagery in televised political campaign advertising upon our electoral system, coupled with the current public interest in this area, could lead to a call for legislation restricting televised political advertisements to a talking head format. This study found that a statute regulating televised political campaign advertisements in this manner would violate the first amendment to the United States Constitution. The regulation of external imagery would not be a valid time, place and manner restriction because external imagery is compatible with messages on the television medium and the regulation of external imagery would not be content-neutral. It is unlikely that the courts would find the regulation to be a valid content-based restriction because a compelling government interest does not exist. This study concludes that the best solution to the problems presented by external imagery in televised political advertising is not for government intervention, but for the citizens and the press to be actively involved in political affairs
Use of Expected Progeny Differences for Marbling in Beef: I. Production Traits
Six Angus bulls with HIGH (\u3e.4) and six bulls with LOW (\u3c-.16) expected progeny differences (EPD) for marbling were used to evaluate the impact of marbling on progeny production and carcass traits. Bulls were randomly bred to MARC II (¼ Hereford, ¼ Simmental, ¼ Angus, ¼ Gelbvieh) composite cows in each of 2 yr to calve in the spring. At weaning, steers and heifers were separated and managed in different production systems. Steers (n = 131) were fed a growing diet (1.1 Mcal of NEg/kg) for 48 d followed by adaptation to a 93% concentrate finishing diet. Heifers (n = 125) were fed a growing diet (.79 Mcal of NEg/kg) for 191 d followed by adaptation to the same 93% concentrate diet. Steers and heifers from each treatment were slaughtered at two times spaced about 60 d apart within both years. Marbling EPD class had no effect on fat thickness, USDA yield grade, carcass weight, finishing daily gain, finishing DMI, or finishing efficiency ( P \u3e .18). More ( P \u3c .05) carcasses of calves from sires with HIGH EPD for marbling graded USDA Choice than from LOW EPD sires, 74% vs 47%, respectively. Angus sires can be selected to produce progeny that have increased ability to grade Choice without increasing yield grade or decreasing animal growth or feed efficiency
Electromagnetic Scanning of Beef Quarters to Predict Carcass and Primal Lean Content
To study the use of electromagnetic scanning in prediction of lean content in beef carcasses and cuts, 100 beef cattle (60 steers and 40 heifers), representing a broad range in external fat thickness (. 1 to 2.9 cm) and live weight (414 to 742 kg), were selected. Chilled right sides were divided into streamlined (foreshank, brisket, and ventral plate removed) forequarters (FQ) and full hindquarters (HQ) and scanned. Primal rounds, loins, ribs, and chucks were fabricated from the right side, scanned, and physically separated into lean, fat, and bone. Prediction equations for dissected lean content and percentage of lean included the peak of the electromagnetic scan response curve (obtained from scanning the HQ or FQ), length, temperature and weight of the scanned cut, and fat thickness at the 12th rib. Using the coefficient of determination, root mean square error, and Mallows\u27 Cp statistic, the best model for each dependent variable (weight and percentage of lean) that included up to five independent variables was selected. Prediction equations for the HQ or FQ of steers accounted for 84 to 93% of the variation in lean weight of beef sides and quarters and 71 to 93% of primals. Sixty-one to 75% of the variation in percentage of lean in sides and quarters and 48 to 65% of primals was also explained. Similar results were obtained for heifer carcasses. Predicting percentage of lean in any scanned cut, rather than weight of lean, accounted for less of the variation. Weight and fat thickness contributed significantly when predicting percentage of lean. These data indicate that electromagnetic scanning is capable of objectively measuring lean content in beef quarters and primals
The effect of cimaterol and its withdrawal on carcass composition and meat tenderness of broiler chickens.
To examine the effects of cimaterol (CIM) and its withdrawal on meat tenderness and carcass composition, 214-old broiler chickens (n = 288) were randomly assigned to one of nine treatments. For Treatments 1 through 6, bids were fed a control diet or a diet containing 1 ppm CIM until slaughter at 35, 42, or 49 d of age. Treatments 7 and 8 consisted of birds fed the CIM diet for 14 d and then withdrawn from CIM for either 7 or 14 d before slaughter (42 or 49 d of age). In Treatment 9, birds were fed the CIM diet to 42 d of age, then withdrawn from CIM for 7 d. Breast muscle (BM) weight, leg muscle (LM) weight, whole body weight, and BM and LM cathepsin B and L activities were obtained on 12 birds/treatment. Body, LM and BM composition and BM shear values were obtained on 12 additional birds/treatment. Eight birds/treatment were used to balance the number of birds per pen. Leg muscle weight, as a percentage of whole body weight, was elevated in CIM-fed birds at all ages, and BM percentage was greater at 35 d of age (P M .05). Leg muscle fat percentage was reduced at 35 and 42 d of age (P \u3c .05), and LM protein was elevated at 42 and 49 d of age (P \u3c .05) in CIM-fed birds. Percentage of protein in the BM of CIM-fed birds was elevated at 35 and 42 d of age. Protein content of the whole body was also increased at 35 d of age. Shear values were higher in 42- and 494-old CIM-fed birds. Withdrawal from CIM increased LM and BM fatness beyond that of controls (P \u3c .05), removed the differences in protein percentage, and removed the detrimental effects on shear value. No differences were found in total cathepsin B and L activities. Broiler chickens fed CIM have increased muscle protein percentage, decreased fat percentage, heavier muscle weights, and reduced meat tenderness. Withdrawal from CIM removed these differences
Influences of Institutional Distance and MNEs’ Host Country Experience on the Ownership Strategy in Cross-border M&As in Emerging Economies
Government size, composition of public expenditure, and economic development
This paper analyzes the effects of government size and of the composition of public expenditure on economic development. Using the system-GMM estimator for linear
dynamic panel data models, on a sample covering up to 156 countries and 5-year periods from 1980 to 2010, we find that government size as a percentage of GDP has a quadratic (inverted U-shaped) effect on the growth rate of the Human Development Index (HDI). This effect is especially pronounced in developed and high income countries. We also find that the composition of public expenditure affects development, with the share of five
subcomponents exhibiting non-linear relationships with HDI growth.COMPETE, QREN, FEDER, Fundação para a Ciência e a Tecnologia (FCT
