Case studies on smallholder farmer voice: an introduction to a special symposium     

Harvey S. James Jr.  Iddisah Sulemana 《Agriculture and Human Values》2014,31(4):637-641

In the spring of 2013, project leaders who received funding from the John Templeton Foundation’s program “Can GM Crops Help to Feed the World?” met in England to discuss progress on funded projects and to identify common objectives and research interests. The collection of essays in this special symposium is one outcome of that meeting. This introduction provides background on the symposium’s theme of understanding the challenges to smallholder farmers having a voice. Farmer voice is important not only in debates about genetically modified crops but also for policies, technologies and other efforts designed by interests seeking ostensibly to improve the livelihoods of smallholder farmers.  相似文献

Effect of active immunization against growth hormone-releasing factor on growth and onset of puberty in beef heifers.   总被引：1，自引：0，他引：1

Angus and Charolais heifers (195 +/- 7 kg) were actively immunized against growth hormone-releasing factor (GRF) to evaluate the effect on concentrations of somatotropin (ST), insulin-like growth factor I (IGF-I), insulin (INS), growth, and onset of puberty. Primary immunizations were given at 184 +/- 7 d of age (d 0 of experiment) by injecting (s.c.) 1.5 mg of GRF-(1-29)-Gly-Gly-Cys-NH2 conjugated to 1.5 mg of human serum albumin (GRFi, n = 22) or 1.5 mg of human serum albumin (HSAi, n = 21). Booster immunizations of .5 mg of antigen were given on d 62, 92, 153, and 251. Antibody binding (percentage at 1:2,000 dilution) to [125I]GRF on d 69 was greater (P less than .01) in GRFi (53.7 +/- 4.5) than in HSAi (10.1 +/- .6) heifers. Serum concentration (ng/ml) and frequency (peaks/5 h) of ST release, respectively, on d 78 were lower (P less than .01) in GRFi than in HSAi heifers (3.3 +/- .1 vs 5.6 +/- .2 and .9 +/- .3 vs 2.3 +/- .2). Serum IGF-I (ng/ml) was lower (P less than .01) in GRFi than in HSAi heifers on d 69 (41 +/- 5 vs 112 +/- 4). Serum INS (microU/ml) on d 78 was lower (P less than .05) in GRFi (2.2 +/- .1) than in HSAi (3.8 +/- .2) heifers. Feed intake, ADG, and feed efficiency were lower (P less than .05) in GRFi than in HSAi heifers. Hip height was lower (P less than .01) and fat thickness was greater (P less than .05) in GRFi than in HSAi heifers by d 132 and 167, respectively. Percentage of heifers attaining puberty (progesterone greater than 1 ng/ml for two consecutive weeks) by d 209 and 379 (12.9 and 18.5 mo of age), respectively, was lower (P less than .05) in GRFi (40.9 and 45.5) than in HSAi (81.0 and 100). In conclusion, growing heifers were successively immunized against GRF. Active immunization against GRF resulted in decreased serum concentration of ST, IGF-I, and INS. In addition, GRF immunization led to lowered feed intake, ADG, and feed efficiency, increased fat depth, and delayed onset of puberty in heifers. We propose that ST and IGF-I are important metabolic mediators involved in the initiation of puberty in heifers.  相似文献   

Endocrine changes in the fowl during infection with Eimeria maxima     

T F Davison  H D Chapman  S Harvey 《Research in veterinary science》1985,38(3):296-300

Plasma concentrations of thyroxine (T4), triiodothyronine (T3), prolactin, growth hormone and corticosterone were measured in immature domestic fowl which were infected with Eimeria maxima, uninfected but given the same amount of food as those infected (pair-fed) or fed ad libitum. Infection with E maxima caused a decrease in plasma T4 concentration whereas pair feeding caused an increase when food intake was minimal. Plasma T3 concentrations were decreased similarly in both infected and pair-fed birds. Infection caused an increase in plasma prolactin concentration, whereas pair-feeding did not. The plasma concentration of growth hormone was not affected by any of the treatments. Plasma corticosterone concentration was markedly increased on days 5 and 6 in pair-fed birds but was not affected by infection with E maxima.  相似文献

Use of PCR-based methodologies for the determination of DNA diversity between Saccharum varieties   总被引：3，自引：0，他引：3  

M. Harvey  F. C. Botha 《Euphytica》1996,89(2):257-265

Summary In this study, two PCR-based methodologies were evaluated for potential use in the determination of DNA diversity between 20 commercial sugarcane hybrids and 6 outgroup varieties of S. spontaneum, S. officinarum and hybrids from early in the genealogy. The first method involved PCR amplification of sugarcane DNA in the presence of random, decamer primers (RAPDs), while the second protocol utilized specific microsatellite and telomere sequences as primers. A total of 41 RAPD primers (356 loci) were screened across the varieties of which 15 (160 loci) were used in the calculation of DNA diversity (expressed% similarity). This varied from 61 to 95%, with most of the commercial varieties showing more than 80% similarity in their DNA. The RAPD data indicated that there had been a gradual decline in DNA diversity (84% reduction) from the early inter-specific crosses to the commercial hybrids, probably as a result of backcrossing and in-breeding strategies used in the previous 5 to 6 generations of sugarcane breeding. The microsatellite and telomere data produced a much greater range in DNA similarity values (25–91%), probably due to the fact that these primers detect highly variable regions of the genome. It is suggested that these specific primers would not be suitable for determination of DNA diversity, but could be used more effectively in the development of a methodology for routine, rapid identification of sugarcane varieties.  相似文献   

Challenging the developmental state: Nature conservation in Singapore     

Harvey Neo 《Asia Pacific viewpoint》2007,48(2):186-199

Abstract: Nature conservation efforts are often reactive to encroaching development plans and systematic conservation planning that is integral with development is not only uncommon, but is often fraught with difficulties even where it is actually attempted. Such obstacles to conservation are especially apparent in developmental states where state legitimacy is largely derived from the state's ability to develop the country. Among other things, developmental states place a premium on physical and economic development. This paper critiques, through the standpoint of nature conservation, the inadequate conceptualisation of ‘development’ in the developmental state thesis. Specifically, this paper argues that the seemingly value‐free (but ultimately economically based) underpinnings of development goals pushed by the developmental state needs to be tempered with a broader concern for the ethics of development. To that end, I draw on two case studies of nature conservation tussles in Singapore to show how alternative extra‐economic visions of development have been articulated, notwithstanding the developmental state's monopoly on the discourse (and practice) of progress and development. The case studies, set in the heady economic growth of the early 1990s, will critique two related aspects of the developmental state: its ‘amoral’ economistic conception of development and its use of growth and materialism as legitimacy.  相似文献
